                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by, and should be read
in conjunction with, the more detailed information and financial statements
appearing elsewhere in, or incorporated by reference in, this Prospectus. Except
where otherwise indicated, the information in this Prospectus assumes that the
over-allotment option granted to the Underwriters is not exercised. All
references to the "Company" or "Tesoro" shall mean Tesoro Petroleum Corporation
and its consolidated subsidiaries, unless the context otherwise requires. All
references to the "Bob West Field" shall mean the approximately 90% of the
acreage in such field in which the Company participates.
 
                                  THE COMPANY
 
     Tesoro is an independent energy company engaged in refining and marketing,
primarily in Alaska, and in the exploration for and production of natural gas
and crude oil in South Texas and Bolivia. The Company also markets lubricants,
fuels and specialty petroleum products on a wholesale basis. In 1993, the
Company's new management team initiated a strategic plan focusing on: (i)
enhancing the profitability of the Company's Kenai, Alaska refinery (the
"Refinery") through a market-driven production strategy, (ii) expanding the
Company's exploration and production efforts in South Texas, (iii) resolving a
contractual dispute with the State of Alaska (the "State") and (iv)
strengthening the Company's capitalization to increase its financial and
operating flexibility. The successful implementation of these new strategic
efforts contributed significantly to an increase in segment operating profit
from $9.5 million in 1992 to $52.3 million in 1993 and to a return to overall
profitability with net earnings of $17.0 million in 1993.
 
     Refining and Marketing. The Company conducts its refining operations in
Alaska, where it is one of the two largest producers of refined products.
Strategically located in Kenai, Alaska on the Cook Inlet, with access to
multiple sources of crude oil, the Refinery has a rated throughput capacity of
72,000 barrels per day ("BPD"). In 1993, Refinery production consisted of
approximately 25% jet fuel, 25% gasoline, 14% other distillates, including
diesel fuel, and 36% residual fuel oil. During 1993, all of the jet fuel was
marketed in Alaska to passenger and cargo airlines, and substantially all of the
other distillates, including diesel fuel, was marketed in Alaska for marine and
industrial purposes. During 1993, approximately 89% of the gasoline was marketed
in Alaska, with the remaining 11% being sold into West Coast markets. Tesoro
holds an exclusive license to operate all 7-Eleven convenience stores within
Alaska, and conducts its retail marketing of gasoline through 33 of the
Company's 7-Eleven stores and two other locations in Alaska. In addition, the
Company markets gasoline on a wholesale basis in Alaska through 67 branded and
24 unbranded dealers and jobbers and to two major oil companies. A majority of
the residual fuel oil produced in 1993 was sold as a feedstock to refineries on
the West Coast.
 
     In response to consistently depressed prices in the residual fuel oil
market and Refinery production of gasoline in excess of local demand, the
Company's new management team implemented a strategy in 1993 to align Refinery
product yield more closely to the product demand of the Alaskan marketplace.
This market-driven strategy resulted in significant changes in the operation of
the Refinery, including: (i) a reduction in Refinery throughput from
approximately 61,000 BPD in 1992 to approximately 50,000 BPD in 1993 and (ii) a
reduction in the percentage of Refinery feedstocks represented by heavier
Alaskan North Slope ("ANS") crude oil, which resulted in a reduction in the
percentage of residual fuel oil produced. In addition, beginning in 1993, the
Company focused on the marketing of residual fuel oil primarily as a feedstock
for West Coast refineries. Changes in Tesoro's sales prices to such refineries
can be linked to changes in crude oil prices, unlike the more volatile Far
Eastern bunker fuel markets where the Company had primarily marketed its
residual fuel oil in the past. The implementation of these measures
significantly contributed to an improvement in the Company's refining and
marketing segment operating results from a $14.9 million loss in 1992 to a $15.2
million profit in 1993. The Company is currently installing a vacuum unit at the
Refinery, which is estimated to cost approximately $24 million and is expected
to result in further significant reductions in the production of residual fuel
oil and to improve the Refinery's overall product mix. The vacuum unit is
expected to begin operating in January 1995.

     Exploration and Production. The Company explores for and produces natural
gas from two geographic areas: South Texas and Bolivia. The Company's South
Texas activities are primarily concentrated in the Bob West Field in the
southern part of the Wilcox Trend in Starr and Zapata Counties. The Bob West
Field, which was discovered by the Company in 1990, represents a major gas
discovery with estimated ultimately recoverable gross proved reserves to all
participants of 334 billion cubic feet ("Bcf") of natural gas, of which
approximately 56 Bcf had been produced through March 31, 1994. The Bob West
Field encompasses approximately 4,000 acres, with 23 known productive sands, 17
of which are now producing. Wells in the Bob West Field, the majority of which
are deviated, are typically multiple sand completions on a faulted anticlinal
structure with production from depths of 8,000 to 16,000 feet. Estimated gross
proved developed reserves per well at March 31, 1994 averaged approximately 7.3
Bcf and gross drilling and completion costs per well drilled in 1993 averaged
approximately $2.8 million. The Company owns an average 50% revenue interest in
approximately two-thirds of the Bob West Field and an average 28% revenue
interest in the remaining one-third.
 
   
     Development of the Bob West Field has been highly successful, and the
Company currently has ownership interests in 31 producing wells in this field,
15 of which were drilled in 1993 at a total cost to the Company of approximately
$21.4 million and six of which were drilled in the first quarter of 1994. An
additional 21 wells are scheduled to be drilled during the remainder of 1994.
During December 1993, the Company's net production from this field averaged 58
million cubic feet ("MMcf") of gas per day, compared to net production of 18
MMcf of gas per day during December 1992. The Company's net proved gas reserves
attributable to this field increased approximately 63% from 74 Bcf at year end
1992 to 120 Bcf at year end 1993. During 1993, approximately 73% of the
Company's production from this field was sold at spot market prices, while the
remainder was sold under a gas purchase contract (the "Tennessee Gas Contract")
to Tennessee Gas Pipeline Company ("Tennessee Gas").
    
 
   
     The Company's other exploration and production operations are located in
southern Bolivia near the border of Argentina, where, since 1976, the Company
has discovered four significant natural gas fields. As a result, Tesoro is the
second largest holder of proved natural gas reserves in Bolivia through its
approximately 75% interest in two contract areas, Blocks XVIII and XX. To date,
only Block XVIII has been developed due to current market and transportation
constraints. In Block XVIII, a 93,000-acre area, the Company has drilled five
exploratory wells and 12 development wells within three separate fields. Wells
in this area are multiple sand completions on an anticlinal structure with
production from depths of 7,000 to 9,700 feet. During 1993, the Company's net
production averaged 19 MMcf of gas per day and 660 barrels ("Bbls") of
condensate per day, a production level that has been maintained for more than
three years. Net proved reserves in Bolivia at year end 1993 were approximately
112 billion cubic feet equivalents, based on the assumption that 5.8 Mcf of
natural gas is equal to one barrel of crude oil ("Bcfe"). Production in Bolivia
is currently sold under a contract to the Bolivian state-owned petroleum
company, Yacimientos Petroliferos Fiscales Bolivianos ("YPFB"), which, in turn,
resells the gas to the Republic of Argentina.
    
 
     In 1993, operating profit of the Company's exploration and production
segment increased 40%, from $29.1 million in 1992 to $40.7 million in 1993. At
year end 1993, the present value of estimated future net revenues from proved
reserves discounted at 10% per annum was $217.8 million on a pre-tax basis. Such
estimate is based in part on the terms of the Tennessee Gas Contract, under
which the Company receives prices greatly in excess of spot market prices. This
contract is currently the subject of litigation. See "Investment Considerations"
and "Legal Proceedings -- Tennessee Gas Contract."
 
     The Recapitalization. In February 1994, the stockholders of the Company
approved a plan of recapitalization (the "Recapitalization") for Tesoro. The
Recapitalization included (i) the reclassification of all of the Company's
outstanding $2.16 Cumulative Convertible Preferred Stock ("$2.16 Preferred
Stock"), including accrued and unpaid dividends thereon of approximately $9.5
million, into Common Stock, (ii) the satisfaction of past accrued and unpaid
dividends of approximately $21.2 million on the Company's $2.20 Cumulative
Convertible Preferred Stock ("$2.20 Preferred Stock"), and (iii) certain other
agreements relating to the terms and conditions of the $2.20 Preferred Stock. In
addition, in February 1994 MetLife Security Insurance Company of Louisiana
("MetLife Louisiana"), a wholly-owned subsidiary of Metropolitan Life Insurance
Company ("MetLife") and the sole holder of the $2.20 Preferred Stock, granted
Tesoro a
 
                                        4
<PAGE>   6
 
three-year option (the "MetLife Louisiana Option") to purchase all of MetLife
Louisiana's holdings of $2.20 Preferred Stock and Common Stock. Until June 30,
1994, the aggregate option price is approximately $53.0 million, after giving
effect to a reduction in the option price for the cash dividend paid on the
$2.20 Preferred Stock in May 1994. The unpaid option price will increase by 3%
on the last day of each calendar quarter through December 31, 1995, and by 3.5%
of the unpaid option price on the last day of each quarter thereafter, and will
be reduced by cash dividends paid on the $2.20 Preferred Stock after February 9,
1994. Also, in February 1994, holders of $44.1 million principal amount of the
Company's 12 3/4% Subordinated Debentures due 2001 ("Subordinated Debentures")
tendered their debentures for a like principal amount of new 13% Exchange Notes
due 2000 ("Exchange Notes"). This exchange satisfied all the Company's sinking
fund requirements through 1996 and over 90% of such requirements for 1997. As a
result of the successful completion of the Recapitalization, the Company's
capital structure has been significantly improved, with stockholders' equity
increasing by approximately $80 million and annual preferred dividend
requirements being reduced by approximately $2.9 million.
 
   
     The Offering. The net proceeds from the Offering will be utilized to
exercise the MetLife Louisiana Option and, if such proceeds exceed the amount
required to exercise the MetLife Louisiana Option in full, for general corporate
purposes. See "Use of Proceeds." If the MetLife Louisiana Option is exercised in
full prior to June 30, 1994, the Company will acquire 2,875,000 shares of $2.20
Preferred Stock having a liquidation value of approximately $57.5 million and
4,084,160 shares of Common Stock having an aggregate market value of
approximately $42.9 million (based on a closing price of $10 1/2 per share on
June 21, 1994) in consideration for $53.0 million. The exercise in full of the
MetLife Louisiana Option will further improve the Company's financial
flexibility by eliminating dividend requirements of $6.3 million per year on the
$2.20 Preferred Stock.
    
 
   
     If the net proceeds from the Offering are less than the full exercise
price, the MetLife Louisiana Option will be exercised in part to the extent of
the net proceeds. The MetLife Louisiana Option provides that any partial
exercise will result in the purchase of a pro rata portion of each of the shares
of Common Stock and the shares of $2.20 Preferred Stock held by MetLife
Louisiana. The Company is currently prohibited under the terms of the indenture
governing the Subordinated Debentures from repurchasing its capital stock,
including the shares of $2.20 Preferred Stock and Common Stock subject to the
MetLife Louisiana Option, except from the proceeds of a substantially concurrent
sale of other shares of capital stock. Accordingly, if the proceeds to the
Company from the Offering are not sufficient to exercise the MetLife Louisiana
Option in full, the Company would be able to exercise the MetLife Louisiana
Option only to the extent of the net proceeds of the Offering.
    
 
   
     Business Strategy. The Company's ongoing business strategy is (i) to
continue to enhance its refining and marketing operations in Alaska and (ii) to
expand its exploration and production operations through development drilling in
the Bob West Field. In addition, management of the Company currently intends to
recommend to the Company's Board of Directors that the Company proceed with a
limited exploration program focused primarily on the Wilcox Trend of South Texas
if the Offering is successfully completed and the MetLife Louisiana Option is
exercised in full. In conjunction with its ongoing exploration and production
operations, the Company from time to time reviews possible acquisitions of
producing oil and gas properties. The Company believes that it will in the
future make such acquisitions to enhance its growth; however, the Company does
not currently have any specific acquisition plans.

                          NOTES TO SUMMARY HISTORICAL
                   CONSOLIDATED FINANCIAL AND OPERATING DATA
 
(1) The Company is involved in litigation with Tennessee Gas relating to a
     natural gas sales contract. For additional information concerning this
     dispute, see "Investment Considerations," "Legal Proceedings -- Tennessee
     Gas Contract" and Notes K and P of Notes to Consolidated Financial
     Statements.
 
(2) Segment operating profit represents pretax earnings (loss) before certain
     corporate expenses, interest income and interest expense.
 
(3) Interest expense in 1993 is net of a $5.2 million credit for settlement of
     several state tax issues (see Note H of Notes to Consolidated Financial
     Statements). Excluding this credit, interest expense for 1993 would have
     been $19.7 million.
 
(4) The net loss for the year ended December 31, 1992 included a charge of $20.6
     million for the cumulative effect of the adoption of Statement of Financial
     Accounting Standards ("SFAS") No. 106, "Employers' Accounting for
     Postretirement Benefit Other than Pensions" and SFAS No. 109, "Accounting
     for Income Taxes." The net earnings for the three months ended March 31,
     1994 include a $4.8 million extraordinary loss related to an early
     extinguishment of debt in connection with the Recapitalization, which was
     completed in February 1994.
 
(5) The Refinery has a rated throughput capacity of 72,000 BPD.
 
(6) All sales of residual fuel oil represent sales of residual fuel oil produced
     at the Refinery.
 
(7) Average finding cost per Mcf represents costs incurred in oil and gas
     property acquisition, exploration and development activities for each
     indicated period divided by the changes in proved reserves resulting from
     extensions, discoveries and other additions and revisions of previous
     reserve quantity estimates during such period. See Note P of Notes to
     Consolidated Financial Statements.
 
(8) The present value of estimated future net revenues from proved reserves
     represents the computation of estimated future net revenues, before
     deduction of income taxes, relating to proved reserves at the end of each
     period presented, discounted at a rate of 10% per annum and assuming no
     escalation in prices. The present value of such estimated future net
     revenues is not intended to be representative of the fair market value of
     the Company's proved reserves. The calculations of revenues and costs used
     to determine the present value of estimated future net revenues from proved
     reserves, before deduction of income taxes, do not necessarily represent
     the amounts to be received or expended by the Company.

                   SELECTED SUMMARY PRO FORMA FINANCIAL DATA
                (DOLLARS IN MILLIONS, EXCEPT PER SHARE AMOUNTS)
 
   
     The following sets forth certain financial data on an historical basis and
as adjusted to give effect to the Recapitalization and the Offering, assuming
net proceeds of $52.3 million, after deduction of $3.2 million of underwriting
discounts and estimated expenses, from the issuance of 5,350,000 shares of the
Company's Common Stock (before the Underwriters' over-allotment option) at an
offering price of $10 3/8 per share pursuant to the Offering. The unaudited
summary pro forma financial data have been prepared assuming the
Recapitalization and the Offering occurred as of January 1, 1993 for statements
of operations and other financial data presentation purposes and on March 31,
1994 for balance sheet data presentation purposes. The pro forma financial data
assume that the proceeds from the Offering are used to exercise the MetLife
Louisiana Option to the extent of such proceeds and take into account the
payment of a cash dividend on the $2.20 Preferred Stock in May 1994 from the
Company's available cash. See "Use of Proceeds." The pro forma financial data
are not necessarily indicative of the Company's results of operations or
financial position in the future or of what the Company's results of operations
or financial position would have been had the transactions been consummated
during the periods, or as of the dates, for which pro forma financial
information is presented. The pro forma financial statements are based upon, and
should be read in conjunction with, "Pro Forma Condensed Consolidated Financial
Data," including the notes thereto, and the Consolidated Financial Statements,
including the notes thereto.

<PAGE>   13
 
                           INVESTMENT CONSIDERATIONS
 
     Prospective purchasers of shares of Common Stock offered hereby should
consider carefully, in addition to the other information contained in, or
incorporated by reference in, this Prospectus, the following matters:
 
     Possible Adverse Impact of Pending Litigation. The Company is involved in
certain litigation regarding a gas purchase contract with Tennessee Gas. Two
producing acreage units within the Bob West Field are subject to the Tennessee
Gas Contract, pursuant to which Tennessee Gas pays prices greatly in excess of
spot market prices ($7.84 per Mcf during March 1994, compared to average spot
market prices for natural gas of $2.09 per Mcf during March 1994). During 1993,
the Tennessee Gas Contract price was paid with respect to approximately 27% of
the Company's net production from the Bob West Field. As of March 31, 1994, the
cumulative difference between the amount that Tennessee Gas has paid for gas
purchases under the Tennessee Gas Contract and the price that would have been
paid based on spot market prices totaled approximately $38.9 million, which the
Company anticipates will continue to increase. If Tennessee Gas ultimately
prevails in this litigation, the Company could be required to return to
Tennessee Gas this difference, plus interest, if awarded by the court. In
addition, the present value of estimated future net revenues on a pre-tax basis
from the Company's proved domestic reserves has been calculated based in part on
the price being paid by Tennessee Gas at the date of determination. At March 31,
1994, such present value was $171.0 million. If calculated using March 31, 1994
spot market prices instead of the contract price, such present value would have
been $92.0 million. The trial court judgment in the case in favor of the Company
was affirmed in part and reversed and remanded to the trial court in part by the
Court of Appeals. Both parties are seeking review of the appellate court ruling
in the Supreme Court of Texas. An adverse judgment in this case could have a
material adverse effect on the Company. See "Legal Proceedings -- Tennessee Gas
Contract" and Notes K and P of Notes to Consolidated Financial Statements.
 
   
     Certain Provisions of Tennessee Gas Contract. Tennessee Gas elected not to
take gas under the Tennessee Gas Contract on June 1, 1994. Subsequently,
Tennessee Gas elected to take gas from June 2, 1994, through the end of the
month. Under normal industry practices, elections to take gas are made on a
monthly basis. Under the terms of the Tennessee Gas Contract, Tennessee Gas is
not required to take gas for any period of a contract year; however, Tennessee
Gas has an obligation to pay for gas not taken at the end of each contract year.
Tennessee Gas has the right, upon one day's notice, to change its elections to
take gas. There is no assurance that Tennessee Gas will continue to elect to
take gas. The failure to take gas could adversely affect the Company's income
and cash flows from operating activities within a contract year, but the Company
should recover lost revenues shortly after the end of the contract year under
the take-or-pay provisions of the Tennessee Gas Contract. The contract year ends
on January 31 of each year.
    
 
     Concentration of Operations. The Company's exploration and production
segment contributed 78% of total operating profit in 1993. Oil and gas
production is subject to interruption as a result of a variety of conditions and
events, including natural disasters, reservoir damage, mechanical difficulties,
unavailability of equipment and supplies, transportation problems, title and
contractual controversies, governmental regulation and others. Because the
Company's domestic oil and gas production is confined to South Texas, primarily
to the Bob West Field, and its international oil and gas operations are confined
to two blocks in Bolivia, the effect of any of such conditions or events on the
Company could be more adverse than if the Company were more geographically
diverse. Any interruption of oil and gas production in any one or more of the
Company's areas of operation could have a material adverse effect on the
Company.
 
     All refinery operations are conducted at the Company's facility in Kenai,
Alaska. As a result, the operations of the Company would be subject to
significant interruption if the Refinery or the dock facilities used by the
Company were to experience a major accident or were damaged by severe weather or
other natural disaster. The Company maintains business interruption insurance
with respect to its Refinery operations in amounts that management of the
Company believes to be adequate.
 
     Potential Interruption of Feedstock Availability. The Refinery currently
utilizes crude oil that is transported through the Trans Alaska Pipeline System
("TAPS") to Valdez, Alaska and from there to the Refinery by the Company's
time-chartered American flag vessel. In connection with an ongoing overhaul of
the electrical systems of the TAPS, numerous electrical code violations have
recently been discovered. While
 
                                       12
<PAGE>   14
 
representatives of the TAPS have indicated that they believe the overhaul of the
electrical system and any action required to remedy such violations will not
cause any significant interruptions in the transportation of crude oil through
the TAPS, there is a possibility that such interruptions could occur as a result
of electrical failure, regulatory action or other matters related to the
overhaul or the violations. In 1993, approximately 72% (35,600 BPD) of the
Refinery's feedstock was ANS crude oil, of which approximately 24,300 BPD was
purchased under a royalty crude oil purchase contract with the State, which is
scheduled to expire at the end of 1994. The Company and the State have agreed in
principle to extend the contract through 1995. During 1994, this contract
requires the Company to purchase approximately 27,500 BPD of ANS crude oil,
which equals approximately 55% of the Company's total feedstock requirements
during 1993. The agreement in principle between the Company and the State would
require the Company to purchase approximately 40,000 BPD of ANS crude oil during
1995, which equals approximately 80% of the Company's total 1993 feedstock
requirements. The Company's remaining feedstock requirements are generally met
through short-term contracts and spot market purchases. In the event of any
significant interruption in this supply or transportation system, the Company
has access to other sources of feedstocks. However, the Company cannot predict
the price or terms on which such alternative feedstock supplies could be
secured, and any such interruption could have a material adverse effect on the
Company's operations.
 
     Volatility of Prices, Earnings and Cash Flows. The markets for crude oil
and natural gas and the refined products produced at the Refinery historically
have been volatile and are likely to continue to be volatile in the future. An
increase in crude oil prices could adversely affect the Company's operating
margins. The Company's operating margins are subject to wide fluctuation in
response to relatively minor changes in the supply of and demand for crude oil
and natural gas and refined petroleum products, market uncertainty and a variety
of additional factors that are beyond the control of the Company. These factors
include the level of consumer product demand, weather conditions, domestic and
foreign government regulations, political conditions in other producing
countries, the actions of the Organization of Petroleum Exporting Countries, the
supply of foreign crude oil and natural gas, the proximity of the Company's gas
reserves to pipelines, the capacities of such pipelines, fluctuations in
seasonal demand, governmental regulations, the price of foreign imports, the
price and availability of alternative fuels and overall economic conditions. The
Company cannot predict the future markets and prices for the Company's natural
gas or refined products. Additionally, depressed worldwide residual fuel oil
markets have had a significantly negative effect on the Company's results of
operations. The Company cannot predict whether the market for residual fuel oil
will improve in the foreseeable future, although current projections indicate
that such markets will continue to be weak.
 
   
     Decreases in the prices of natural gas have had, and could have in the
future, an adverse effect on the carrying value of the Company's proved reserves
and the Company's revenues, profitability and cash flow. Currently, spot natural
gas prices (Henry Hub) are more favorable than they have been in the past;
however, such prices have been extremely volatile over the last 30 months,
ranging from a low of $1.03 per million British thermal units ("MMBtu") in
January 1992 to a high of $3.24 per MMBtu in February 1994. The average Henry
Hub price for 1993 was $2.21 per MMBtu versus $1.80 per MMBtu for 1992.
    
 
     Proposed Pipeline Rate Increase. The Company transports its crude oil and a
substantial portion of its refined products utilizing Kenai Pipe Line Company's
("KPL") pipeline and marine terminal facilities in Kenai, Alaska. In March 1994,
KPL filed a revised tariff with the Federal Energy Regulatory Commission
("FERC") for dock loading services, which would have increased the Company's
annual cost of transporting products through KPL's facilities from $1.2 million
to $11.2 million, or an increase of $10 million per year. Following the FERC's
rejection of KPL's tariff and the commencement of negotiations for the purchase
by the Company of the dock facilities, KPL filed a temporary tariff that would
increase the Company's cost on an annual basis by approximately $1.5 million.
The negotiations between the Company and KPL are continuing. The Company
believes that the ultimate resolution of this matter will not have a material
adverse effect upon the financial condition or results of operations of the
Company.
 
     Environmental Regulations and Liabilities. The Company is subject to
extensive federal, state and local laws and regulations governing releases into
the environment and the storage, transportation, disposal and cleanup of
hazardous waste materials. Future environmental regulations could result in
increased capital expenditures and operating costs that may adversely affect the
Company's results of operations and financial
 
                                       13

condition. At present, the Company has been identified by the U.S. Environmental
Protection Agency (the "EPA") as a potentially responsible party ("PRP")
pursuant to the Comprehensive Environmental Response, Compensation, and
Liability Act ("CERCLA") for two Superfund sites. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations -- Environmental,"
"Business -- Government Regulation and Legislation" and "Legal
Proceedings -- Mud and Gulf Coast Superfund Sites." While the Company has from
time to time been, and presently is, the subject of litigation and
investigations relating to environmental and related matters, management of the
Company believes that such proceedings will not have a material adverse effect
on the results of operations or competitive position of the Company. However,
there can be no assurance that the Company will not become involved in further
litigation or other proceedings, or that if the Company were to be held
responsible for damage in any litigation or proceedings (including existing
ones), such costs would not be material. See "Business -- Government Regulation
and Legislation" and "Legal Proceedings."
 
     The Company currently operates service stations in Alaska, and has in the
past operated service stations in other jurisdictions, that have underground
fuel storage tanks. All such storage tanks are subject to governmental
regulation and legislation. See "Business -- Government Regulation and
Legislation." The operation of underground storage tanks poses certain risks
apart from costs associated with regulatory requirements. These risks are
predominately damages associated with underground leaks of petroleum products.
The Company currently has leak detection and tank testing programs in effect in
Alaska to mitigate the threat of such risks. In addition, the majority of the
Company's operating service stations are in nonresidential locations, further
reducing the risks associated with contamination of residential areas. However,
there can be no assurance that the Company will not become liable for damages
from its underground storage tanks at some future date.
 
     Uncertainty in Estimating Oil and Gas Reserves. There are numerous
uncertainties inherent in estimating quantities of proved reserves of oil and
gas and in projecting future rates of production and timing of development
expenditures, including many factors beyond the control of the Company. The
reserve data set forth in this Prospectus represent only estimates. In addition,
the present value of estimated future net revenues from proved reserves of the
Company is based upon certain assumptions about future production levels, prices
and costs that may not prove correct over time. For information concerning the
risk of litigation which, if adversely determined, could affect such estimates,
see " -- Possible Adverse Impact of Pending Litigation" and "Legal
Proceedings -- Tennessee Gas Contract."
 
     The Company periodically reviews the carrying value of its oil and gas
properties under the full-cost accounting rules of the Securities and Exchange
Commission (the "SEC" or the "Commission"). Under the full-cost accounting
rules, capitalized costs of oil and gas properties may not exceed the present
value of estimated future net cash flows from proved reserves on an after-tax
basis, discounted at 10% per annum, plus the lower of cost or fair market value
of unproved properties. Application of this rule generally requires pricing
future revenues at the unescalated prices in effect as of the end of each fiscal
quarter and requires a write-down if the "ceiling" is exceeded, even if prices
declined for only a short period of time. The risk that the Company will be
required to write down the carrying value of its crude oil and natural gas
properties increases when crude oil and natural gas prices are depressed or
unusually volatile.
 
     Depletion of Reserves; Risk of Oil and Gas Operations. The Bob West Field
has a relatively short reserve life of approximately 5.8 years based on December
1993 production levels. The Company expects to increase future production rates,
which may result in more rapid depletion of this field. Without the acquisition
of producing properties or successful drilling of new wells, the Company's
production and reserves will decline. To the extent the Company engages in
drilling activities, such activities carry the risk that no commercially viable
oil and gas production will be obtained. The cost of drilling, completing and
operating wells is often uncertain. Moreover, drilling may be curtailed, delayed
or canceled as a result of many factors, including title problems, regulatory
delays, weather conditions and shortages or delays in delivery of equipment, as
well as the financial instability of well operators, major working interest
owners and well servicing companies.
 
     Possible Limitation on Use of Tax Benefits. Under Sections 382 and 383 of
the Internal Revenue Code of 1986, if the Company has an "ownership change," as
defined therein, the Company's use of its net operating
 
                                       14
<PAGE>   16
 
   
loss carryforwards and general business credits after the ownership change will
be subject to an annual limit (the "382 Limit"). The Company intends to take the
position that an ownership change under existing law has not occurred as a
result of the Recapitalization and will not occur as a result of the Offering
and the exercise in full of the MetLife Louisiana Option. Because there are
substantial interpretive questions concerning the application of Sections 382
and 383 and because changes in ownership of the Company occurring within three
years after the Offering and the exercise of the MetLife Louisiana Option are
taken into account in determining whether an ownership change has occurred,
there can be no assurance that an ownership change will not occur as a result of
the Offering and the exercise of the MetLife Louisiana Option or as a result of
future events. If an ownership change occurs as a result of the Offering and the
exercise of the MetLife Louisiana Option, the 382 Limit, based on the market
value of the Common Stock on June 21, 1994, could be as low as approximately
$12.0 million per year. The Company's net operating loss carryforwards and
general business credits at December 31, 1993 were approximately $71.1 million
and $8.2 million, respectively.
    
 
     Foreign Operations. A portion of the Company's operations are conducted in
foreign countries, where the Company is subject to risks of a political nature
and other risks inherent in foreign operations. The Company's operations outside
the United States have been, and in the future may be, materially affected by
host governments through increases or variations in taxes, royalty payments,
export taxes and export restrictions and adverse economic conditions in the
foreign countries, the future effects of which the Company is unable to predict.
 
     Operating Hazards. The Company's oil and gas and refining operations are
hazardous due to the combination of individuals and machines operating in
restricted work areas and the highly flammable nature of crude oil, natural gas
and refined products. As a result, the Company has experienced personal injury
and property damage incidents in the past and expects such incidents to occur in
the future. The frequency and severity of such incidents affect the Company's
operating costs, insurability and relationships with customers, employees and
regulators. Any significant increase in the frequency or severity of such
incidents, or the general level of compensation awards with respect thereto,
could affect the ability of the Company to obtain insurance and could have a
material adverse effect on the Company.
 
     Competition. The oil and gas industry is highly competitive in all phases,
including the refining and marketing of crude oil and petroleum products and the
search for and development of oil and gas reserves. The industry also competes
with other industries that supply the energy and fuel requirements of
industrial, commercial, individual and other consumers. The Company competes
with a substantial number of major integrated oil companies and other companies
having materially greater financial and other resources. These competitors have
a greater ability to bear the economic risks inherent in all phases of the
industry. In addition, unlike the Company, many competitors also produce large
volumes of crude oil, which may be used in connection with their refining
operations. The North American Free Trade Agreement has further streamlined and
simplified procedures for the importation and exportation of gas among Mexico,
the United States and Canada. These changes are likely to enhance the ability of
Canadian and Mexican producers to export natural gas to the United States,
thereby further increasing competition in the domestic natural gas market.
 
                                  THE COMPANY
 
     Tesoro is an independent energy company engaged in refining and marketing,
primarily in Alaska, and in the exploration for and production of natural gas
and crude oil in South Texas and Bolivia. The Company also markets lubricants,
fuels and specialty petroleum products on a wholesale basis. The Company was
organized under the laws of the State of Delaware in 1968. Its principal
executive offices are located at 8700 Tesoro Drive, San Antonio, Texas 78217,
and its telephone number is (210) 828-8484.
 
                                USE OF PROCEEDS
 
   
     The net proceeds from the Offering are estimated to be approximately $52.3
million ($57.2 million if the over-allotment option is exercised), after
deduction of underwriting discounts and estimated expenses. The
    
 
                                       15
<PAGE>   17
 
   
Company will use such proceeds to exercise the MetLife Louisiana Option. Any net
proceeds in excess of the amount required to exercise the MetLife Louisiana
Option in full will be used for general corporate purposes. The aggregate amount
required to exercise the MetLife Louisiana Option in full prior to June 30,
1994, is approximately $53.0 million, after giving effect to a reduction in the
option price for the cash dividend paid on the $2.20 Preferred Stock in May
1994. If the MetLife Louisiana Option is exercised in full prior to June 30,
1994, the Company will acquire 2,875,000 shares of $2.20 Preferred Stock having
a liquidation value of approximately $57.5 million and 4,084,160 shares of
Common Stock having an aggregate market value of $42.9 million (based on a
closing price of $10 1/2 per share on June 21, 1994) in consideration for
approximately $53.0 million. Upon the exercise in full of the MetLife Louisiana
Option, dividend requirements of $6.3 million per year on the $2.20 Preferred
Stock would be eliminated.
    
 
     If the net proceeds from the Offering are less than the full exercise
price, the MetLife Louisiana Option will be exercised in part to the extent of
the net proceeds. The MetLife Louisiana Option provides that any partial
exercise will result in the purchase of a pro rata portion of each of the shares
of Common Stock and the shares of $2.20 Preferred Stock held by MetLife
Louisiana. The Company is currently prohibited under the terms of the indenture
governing the Subordinated Debentures from repurchasing its capital stock,
including the shares of $2.20 Preferred Stock and Common Stock subject to the
MetLife Louisiana Option, except from the proceeds of a substantially concurrent
sale of other shares of capital stock. Accordingly, if the proceeds to the
Company from the Offering are not sufficient to exercise the MetLife Louisiana
Option in full, the Company would be able to exercise the MetLife Louisiana
Option only to the extent of the net proceeds of the Offering.
 
                PRICE RANGE OF COMMON STOCK AND DIVIDEND POLICY
 
   
     The Common Stock is listed on the New York Stock Exchange and Pacific Stock
Exchange under the symbol "TSO." The following table sets forth, on a per share
basis, the high and low sales prices of the Common Stock on the New York Stock
Exchange - Composite Tape, as reported by the Dow Jones News/Retrieval Service,

     Certain provisions of the Company's Revolving Credit Facility (as
hereinafter defined) and the indenture governing the Subordinated Debentures
effectively prohibit the Company from currently paying cash dividends on Common

and does not anticipate paying cash dividends on Common Stock in the foreseeable
future.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
RESULTS OF OPERATIONS
 
     Effective January 1, 1992, the Company changed its fiscal year end from
September 30 to December 31. Accordingly, the information contained herein
addresses the Company's results of operations for the year ended December 31,
1993 compared to the years ended December 31, 1992 and September 30, 1991. The
results of operations for the three-month period from October 1, 1991 to
December 31, 1991 are discussed separately. Also included herein are the
Company's results of operations for the three months ended March 31, 1994
compared to the three months ended March 31, 1993.
 
     Net earnings of $2.4 million, or $.03 per share, for the three months ended
March 31, 1994 ("1994 quarter") compare to a net loss of $2.9 million, or $.37
per share, for the three months ended March 31, 1993 ("1993 quarter"). The
comparability between these two periods was impacted by certain transactions.
The 1994 quarter included a non-cash extraordinary loss of $4.8 million on the
extinguishment of debt in connection with the Recapitalization. Earnings before
the extraordinary loss were $7.2 million, or $.27 per share, for the 1994
quarter. Also included in the 1994 quarter was a $2.8 million gain on the sale
of the Company's Valdez, Alaska terminal. The 1993 quarter included a gain of
$1.4 million on the repurchase and retirement of $11.25 million principal amount
of Subordinated Debentures at market value. Excluding these transactions from
both periods, the improvement in the 1994 quarter as compared to the 1993
quarter was primarily attributable to higher natural gas prices on increased
natural gas production from the Bob West Field and improved gross margins in the
refining and marketing operations.
 
     Net earnings of $17.0 million ($.54 per share) in 1993 compare to a net
loss of $65.9 million ($5.34 per share) in 1992. Each of the Company's operating
segments, together with reduced corporate expenses, contributed to the
substantial improvement in 1993.
 
     The comparability of 1993 and 1992, however, was impacted by certain
significant transactions. During 1993, the Company's earnings benefited from the
resolution of several state tax issues, resulting in a net reduction of $3.0
million in income tax expense and $5.2 million in interest expense. In addition,
a gain of $1.4 million was recognized in 1993 for the retirement of $11.25
million principal amount of Subordinated Debentures, which were purchased in
January 1993 for $9.7 million cash to satisfy the initial sinking fund
requirement. The 1992 loss included charges of $20.6 million for the cumulative
effect of accounting changes, $10.5 million for settlement of a contractual
dispute with the State and $9.1 million for a cost reduction program and other
employee terminations, partially offset by a gain of $5.8 million from the sale
of the Company's Indonesian operations. Excluding these significant transactions
for both years, the improvement in 1993 as compared to 1992 was attributable to
increased gross margins on sales of refined products, increased natural gas
production from the Bob West Field and reduced general and administrative
expenses.
 
     The net loss of $65.9 million ($5.34 per share) in 1992 compares to net
earnings of $3.9 million (a loss of $.37 per share after preferred dividend
requirements) in 1991. As described above, several significant transactions
contributed to the net loss in 1992. Excluding these transactions, the decrease
in results of operations in 1992 as compared to 1991 was primarily due to lower
operating results from the Company's refining and marketing operations and
reduced revenues from the Company's Bolivian and Indonesian operations,
partially offset by increased production and sales prices of natural gas from
the Bob West Field.

     Three Months Ended March 31, 1994 Compared to Three Months Ended March 31,
1993. Revenues decreased in the 1994 quarter as compared to the 1993 quarter,
primarily due to an 18% reduction in sales volumes of refined products. The
reduction in volumes resulted from the Company's market-driven operating
strategy implemented in 1993, which more closely aligns Refinery production with
market demand in Alaska while minimizing the output of lower value residual fuel
oil. Costs of sales were lower in the 1994 first quarter, due to the reduced
throughput level together with a decrease in crude oil prices. Included in
operating expenses and other above for the 1994 quarter was the $2.8 million
gain from the sale of the Company's Valdez, Alaska terminal. The overall
improvement in gross margin and the gain on sales of assets were partially
offset by a $2.1 million increase in operating expenses which included higher
environmental and transportation costs.

     Second Quarter of 1994 -- Anticipated Results. Decreased production of ANS
crude oil as a result of seasonal maintenance of TAPS coupled with an increased
demand for ANS crude oil for use as a feedstock in West Coast refineries and the
general increase in the world price for crude oil have resulted in an increase
in the cost of ANS crude oil to the Refinery during the second quarter of 1994.
Sales prices of refined products produced at the Refinery have not increased
proportionately and, as a result, refined product margins during the second
quarter of 1994 have been depressed. The Company anticipates that such
conditions will result in the Company experiencing a small net loss for the
second quarter of 1994 and will thereafter adversely affect results for so long
as such conditions exist.
    
 
     1993 Compared to 1992. During 1993, the Company implemented a market-driven
operational strategy, which emphasizes the upgrading of Refinery feedstocks and
more closely matching production of the Refinery with the refined product demand
within Alaska. This strategy has resulted in a reduction in the Company's
overall Refinery production, particularly lower-valued residual fuel oil. The
markets for residual fuel oil have been weak due to the global oversupply of
this product since the Persian Gulf War, and current projections indicate that
such markets will continue to be weak in the future.
 
     In implementing the Company's new refining and marketing operational
strategy, the Company reduced its average daily Refinery throughput during 1993
by 19% from the 1992 level. This reduction in throughput has enabled the Company
to reduce the portion of lower quality ANS crude oil in the feedstock blend. By
utilizing a greater percentage of higher quality feedstocks (which results in
production yields with greater margins than production yields from a higher
percentage of lower quality crude oil), the Company can successfully operate the
Refinery at the reduced throughput levels. Operating the Refinery at lower
throughput levels results in less production of certain products, particularly
residual fuel oil, for which there is no significant market in Alaska and which
therefore must be exported from Alaska and sold into West Coast and Far Eastern
markets. Implementation of this strategy has resulted in an improvement in the
Company's aggregate Refinery gross margin, enabling the Company to operate the
Refinery more profitably at the lower throughput level.
 
     The decrease in volumes was a significant factor in the change in revenues
in 1993 as compared to 1992. Average sales prices were essentially unchanged;
however, average margins increased in 1993, particularly with regard to sales of
Refinery production. Partially offsetting the decrease in revenues from refined
products was a $33.8 million increase in sales of crude oil. Costs of sales in
1993 decreased due to lower volumes and prices and to the $10.5 million charge
in 1992 for settlement of a contractual dispute with the State relating to the
purchase of crude oil. The $30.1 million improvement in overall operating profit
was primarily due to the improved margins on refined product sales, part of
which was attributable to the favorable market conditions during the fourth
quarter of 1993. While the price of crude oil dropped in the 1993 fourth
quarter, the Company's refined product margins held steady or improved.
 
     1992 Compared to 1991. Revenues from the sales of refined products
decreased 15% in 1992 as compared to 1991. Although volumes decreased only 3%,
average sales prices decreased almost 12%. The $34.2 million decrease in
operating results was primarily due to a further deterioration of gross margins
on refined product sales, particularly residual fuel oil. The recovery of crude
oil costs at the Refinery continued to be adversely impacted by weak markets for
the Refinery's output of residual fuel oil, which approximated 40% of the total
output of the Refinery during 1992 and the prior two years. During the latter
months of 1992, the Company also incurred additional costs to produce oxygenated
gasoline in response to certain environmental requirements. The market for
oxygenated gasoline was such that the additional costs to produce the oxygenated
gasoline could not be entirely recovered with increased sales prices. Such
environmental requirements were suspended in December 1992. See "Business --
Government Regulation and Legislation." In addition to increased operating costs
for environmental issues and reductions in workforce, operating results for 1992
also included higher costs of sales resulting from the settlement of the
contractual dispute with the State. These increases in operating costs were
partially offset by a transportation rebate received in 1992.

     Three Months Ended March 31, 1994 Compared to Three Months Ended March 31,
1993. The number of producing wells in South Texas in which the Company has an
interest increased to 33 at the end of the 1994 quarter compared to 11 at the
end of the 1993 quarter. The resulting increase in the Company's production
levels in South Texas, together with higher average sales prices, contributed to
the higher revenues. Total lifting costs and depreciation, depletion and
amortization also increased in the 1994 quarter due to the higher production
levels.
 
     The 1994 quarter production level, which was higher than the 1993
quarter's, was lower than the 58 MMcf per day produced during the three months
ended December 31, 1993. Beginning in February 1994, the common carrier pipeline
facilities transporting gas from the Bob West Field were at capacity and the
Company's production from the field was curtailed. The curtailment affected only
production subject to spot market prices, and the Company continued to produce
and transport all of its gas in the Bob West Field subject to the Tennessee Gas
Contract. Accordingly, the average realized selling price for the Company's
domestic natural gas was $3.92 per Mcf during the 1994 quarter, which compares
to $3.07 per Mcf in the 1993 quarter. A new common carrier pipeline began
transporting the increased gas production from the Bob West Field in May 1994.
The Company believes that there should now be adequate transportation for all of
its gas production from the Bob West Field. See "Investment Considerations,"
"Legal Proceedings -- Tennessee Gas Contract" and Notes K and P of Notes to
Consolidated Financial Statements regarding litigation involving the Tennessee
Gas Contract.
 
   
     Tennessee Gas elected not to take gas under the Tennessee Gas Contract on
June 1, 1994. Subsequently, Tennessee Gas elected to take gas from June 2, 1994,
through the end of the month. Under normal industry practices, elections to take
gas are made on a monthly basis. Under the terms of the Tennessee Gas Contract,
Tennessee Gas is not required to take gas for any period of a contract year;
however, Tennessee Gas has an obligation to pay for gas not taken at the end of
each contract year. Tennessee Gas has the right, upon one day's advance notice,
to change its elections to take gas. There is no assurance that Tennessee Gas
will continue to elect to take gas. The failure to take gas could adversely
affect the Company's income and cash flows from operating activities within a
contract year, but the Company should recover lost revenues shortly after the
end of the contract year under the take-or-pay provisions of the Tennessee Gas
Contract. The contract year ends on January 31 of each year.
    
 
   
     Results from the Company's Bolivian operations improved by $.5 million when
comparing the 1994 quarter to the 1993 quarter. Under a sales contract with
YPFB, the Company's Bolivian natural gas production is sold to YPFB, which in
turn sells the natural gas to the Republic of Argentina. The contract between
YPFB and the Republic of Argentina has recently been extended for an additional
three-year period ending March 31, 1997. The contract extension will maintain
approximately the same volumes, but with a small decrease in price. The
Company's contract with YPFB, including the pricing provision, is presently
subject to renegotiation for up to a three-year period. The Company expects such
renegotiation with YPFB to commence in July 1994. As a result of the terms of
the contract extension between YPFB and the Republic of Argentina, the Company
expects the renegotiation to result in a corresponding small decrease in the
contract price. The renegotiation could also result in a reduction of volumes
purchased from the Company due to new supply sources anticipated to commence
producing near the end of 1994.
    
 
     1993 Compared to 1992. Successful development drilling in the Bob West
Field in South Texas was the primary contributing factor to this segment's
improvement in 1993. The number of producing wells increased to 25 at the end of
1993 compared to 10 at the end of 1992, resulting in a significant increase in
natural gas production. The increase in revenues was primarily caused by these
higher production levels, partially offset by a slight decline in average sales
prices to $3.55 per Mcf in 1993, as compared to $3.68 per Mcf in 1992. Total
lifting costs and depreciation, depletion and amortization increased in 1993 due
to the higher production volumes; however, the depletion rate decreased due to
the 63% increase in proved reserves.
 
     The Company's Bolivian operations experienced a decline in revenues
primarily due to reduced contractual sales prices for the natural gas
production.
 
     The 1992 operating results from the Indonesian operations, which were sold
effective May 1, 1992, included a gain from the sale of $5.8 million.

     1992 Compared to 1991. The operating profit decline in this segment during
1992 as compared to 1991 was primarily due to reduced sales prices and
production levels of crude oil from the Company's former Indonesian operations,
which were sold effective May 1, 1992, and contractually reduced sales prices
for the Company's natural gas production in Bolivia, also effective May 1, 1992.
These decreases in 1992 were partially offset by the $5.8 million gain from the
sales of the Indonesian operations and increased natural gas production and
sales prices from the Bob West Field.

</TABLE>
 
     Three Months Ended March 31, 1994 Compared to Three Months Ended March 31,
1993. Operating expenses and other for the 1994 quarter included a charge of
approximately $.9 million for winding up the Company's environmental products
marketing operations. The Company is continuing its wholesale marketing of fuels
and lubricants.
 
     1993 Compared to 1992. Revenues and costs of sales in this segment during
1993 decreased when compared to 1992 due to the discontinuance, in the 1992
second quarter, of the operation of a wholesale distribution facility in
Oklahoma. In addition, the decrease in crude oil prices during 1993 resulted in
a correlative decrease in refined product prices. Notwithstanding such
decreases, margins on both refined product and merchandise sales improved in
1993, due to the consolidation of certain of the Company's locations and
elimination of marginally profitable locations, including the facility in
Oklahoma. Strong competition in an oversupplied market continues to adversely
impact this segment. Effective at the 1992 year end, the Company acquired the
remaining 50% interest in Tesoro-Leevac Petroleum Company, a joint venture,
which allowed the Company to consolidate certain of its marine terminals;
however, this acquisition did not have a material impact on the revenues or
margins of this segment in 1993.
 
     1992 Compared to 1991. Revenues from the sales of refined products
decreased in 1992 as compared to 1991, primarily as a result of the Company's
discontinuance, in the 1992 second quarter, of the operation of the wholesale
distribution facility in Oklahoma. In addition, refined product sales prices and
margins decreased as a result of a generally weak U.S. economy, continuing
overall depressed drilling activity and an oversupply of refined products
following the Persian Gulf War. The operating loss of $4.7 million in 1992 was a
further deterioration from the operating loss of $.5 million in 1991. This
overall decrease was mainly attributable to lower margins on refined product
sales.
 
  General and Administrative Expenses
 
     There was no significant change in general and administrative expenses in
the 1994 quarter compared to the 1993 quarter. General and administrative
expenses of $16.7 million in 1993 compare to $25.9 million in 1992 and $17.0
million in 1991. The decrease in 1993 was primarily due to the inclusion in 1992
of expenses for a cost reduction program and other employee terminations in 1992
totaling $9.1 million, of which $1.3 million was charged to the operating
segments. There were no significant comparable charges recorded in 1993. The
remaining decrease in 1993 was attributable to the effects of the cost reduction
program. The increase in 1992 as compared to 1991 was mainly due to expenses for
the cost reduction program in 1992.

  Interest and Other Income
 
     Other income in the 1993 quarter included a $1.4 million gain from the
purchase and retirement of $11.25 million principal amount of Subordinated
Debentures in January 1993. Since this retirement satisfied the sinking fund
requirement due in March 1993, the gain was not reported as an extraordinary
item. Interest income of $1.8 million in 1993 compares to $3.2 million in 1992
and $4.2 million in 1991. The decreases in interest income in 1993 and 1992 were
due to lower interest rates on less cash available for investment. During 1993
and 1991, the Company had no major asset sales; 1992 included a $5.8 million
gain from the sale of the Company's Indonesian operations, partially offset by a
$1.8 million loss from the sale of drilling rigs and costs related to the
disposition of the Company's remaining oil field tool rental assets. Other
income increased in 1993 as compared to 1992 due to the $1.4 million gain from
the purchase and retirement of Subordinated Debentures in January 1993.
 
  Interest Expense
 
     There was no significant change in interest expense in the 1994 quarter
compared to the 1993 quarter. Interest expense of $14.5 million in 1993 compares
to $21.1 million in 1992 and $18.8 million in 1991. The decrease in 1993 was
mainly due to a reduction of $5.2 million for resolution of outstanding issues
with several state taxing authorities.
 
  Income Taxes
 
     The increase of $.8 million in the income tax provision during the 1994
quarter as compared to the 1993 quarter was due to federal and state income
taxes on the Company's increased taxable earnings. Income taxes of $1.7 million
in 1993 compare to $5.4 million in 1992 and $15.1 million in 1991. The decrease
in 1993 included a reduction of $3.0 million for resolution of outstanding
issues with several state taxing authorities. In addition, foreign income taxes
continued to decrease in 1993 and 1992 due to reduced revenues from the
Company's Bolivian and former Indonesian operations.
 
  Three Months Ended December 31, 1991 Compared to the Three Months Ended
December 31, 1990
 
     The Statements of Consolidated Operations and Statements of Consolidated
Cash Flows for the three months ended December 31, 1991 are presented in the
Consolidated Financial Statements. For discussion purposes, results for the
three months ended December 31, 1991 are compared to the unaudited three-month
period ended December 31, 1990, as set forth in Note C of Notes to Consolidated
Financial Statements.
 
     The net loss of $.4 million for the three months ended December 31, 1991
(the "1991 quarter") represented a decrease of $5.3 million from the net
earnings of $4.9 million recorded during the three months ended December 31,
1990 (the "1990 quarter"). Total revenues of $243.9 million for the 1991 quarter
decreased $92.3 million from the 1990 quarter, largely due to lower sales prices
for refined products. The 1990 quarter had been impacted by escalating refined
product and crude oil prices during the conflict in the Persian Gulf. During the
1991 quarter, the Company's exploration and production operations in Indonesia
realized lower sales prices on reduced crude oil production as compared to the
1990 quarter. Also contributing to the decrease in total revenues in the 1991
quarter was reduced interest income resulting from lower interest rates on less
cash available for investment. Partially offsetting these decreases in the 1991
quarter were revenues from the Company's convenience store operations in Alaska
and other income resulting from settlement of a matter in litigation. Costs of
sales and operating expenses decreased $83.4 million in the 1991 quarter as
compared to the 1990 quarter, due primarily to the lower prices of crude oil and
refined products, partially offset by costs from the Company's convenience store
operations.
 
     The refining and marketing segment's operating profit of $1.7 million in
the 1991 quarter was a decrease of $.8 million from the $2.5 million operating
profit recorded in the 1990 quarter. The decrease was primarily due to lower
sales prices for residual fuel oil, which continued to be adversely impacted by
the weak markets for this product.

     The exploration and production segment's operating profit of $7.4 million
in the 1991 quarter decreased $8.2 million from the $15.6 million operating
profit recorded in the 1990 quarter. The decrease was mainly due to lower crude
oil sales prices on reduced production volumes from the Company's Indonesian
operations. The Company's Indonesian crude oil production decreased by 1,435
BPD, with an average sales price of $20.57 per Bbl during the 1991 quarter as
compared to $29.39 per Bbl during the 1990 quarter. The Company's operations in
Bolivia also experienced lower natural gas sales prices on reduced production
volumes in the 1991 quarter. Natural gas production from the Company's Bolivian
operations decreased by 487 Mcf per day, with an average sales price of $2.42
per Mcf during the 1991 quarter, as compared to $2.92 per Mcf in the 1990
quarter. The Company's natural gas production in the Bob West Field increased
during the 1991 quarter; however, revenues from this production were
substantially offset by increased depreciation and depletion, insurance costs
and legal fees associated with these operations.
 
     The oil field supply and distribution segment's operating loss of $1.2
million in the 1991 quarter was a decrease of $2.8 million from the $1.6 million
operating profit recorded in the 1990 quarter. This decrease in operating
results was primarily attributable to lower margins on refined product sales
caused by the decline in drilling rig activity in the United States. The 1990
quarter included the effect of increased demand experienced during the Persian
Gulf conflict.
 
     General and administrative expenses of $2.8 million for the 1991 quarter
decreased by $1.2 million from the 1990 quarter, primarily due to an insurance
reimbursement during the 1991 quarter for certain costs incurred in defense of
litigation in prior years. Depreciation, depletion and amortization expense of
$4.2 million in the 1991 quarter increased by $1.2 million from the 1990
quarter, due mainly to exploration and production activities in the Bob West
Field. The income tax provision of $3.0 million in the 1991 quarter decreased by
$3.8 million from the 1990 quarter, primarily due to lower foreign taxes
resulting from reduced revenues from the Company's operations in Indonesia.
 
CAPITAL RESOURCES AND LIQUIDITY
 
     During the first quarter of 1994, the Company continued to achieve
significant improvement in profitability, resulting primarily from (i) strong
gross margins on the sales of refined products, (ii) the Company's recently
implemented market-driven operating strategy to better align Refinery production
with refined product demand in the Alaskan market and minimize the output of
lower value residual fuel oil and (iii) higher natural gas production resulting
from continuing success in developing the Bob West Field. The Company's
liquidity and capital resources have been significantly enhanced as a result of
the Company's improvement in profitability, together with the completion of the
Recapitalization in February 1994 and the finalization of the Company's
Revolving Credit Facility during April 1994.
 
     Significant components of the Recapitalization were as follows:
 
     - Subordinated Debentures in the principal amount of $44.1 million were
       tendered in exchange for a like principal amount of new Exchange Notes,
       which satisfied the 1994 sinking fund requirements and, except for $.9
       million, will satisfy sinking fund requirements for the Subordinated
       Debentures through 1997. The Exchange Notes bear interest at 13% per
       annum, are scheduled to mature on December 1, 2000 and have no sinking
       fund requirements.
 
   
     - The 1,319,563 outstanding shares of $2.16 Preferred Stock, together with
       accrued and unpaid dividends of $9.5 million at February 9, 1994, were
       reclassified into 6,465,859 shares of Common Stock. The Company also
       agreed to issue up to 131,956 shares of Common Stock on behalf of the
       holders of $2.16 Preferred Stock and to pay $500,000 for certain of their
       legal fees and expenses in connection with the settlement of litigation
       related to the reclassification. The court awarded $500,000 and 73,913
       shares of Common Stock for such legal fees and expenses, and 1,127 shares
       to counsel retained by a party objecting to the settlement, with the
       remaining 56,916 shares to be issued to the former holders of $2.16
       Preferred Stock. The shares awarded to counsel for the holders of $2.16
       Preferred Stock have been issued; the shares to be issued to the former
       holders of $2.16 Preferred Stock and to counsel for the objecting party
       will be issued upon the court's orders becoming final and nonappealable.
       See "Legal Proceedings -- Recapitalization Matters."

<PAGE>   29
 
     - The Company and MetLife Louisiana, the holder of all the Company's
       outstanding $2.20 Preferred Stock, entered into an agreement (the
       "Amended MetLife Memorandum") with regard to such preferred shares
       pursuant to which MetLife Louisiana agreed to waive all existing
       mandatory redemption requirements, to consider all accrued and unpaid
       dividends thereon through February 9, 1994 (aggregating approximately
       $21.2 million) to have been paid, to allow the Company to pay future
       dividends in Common Stock in lieu of cash, to waive or refrain from
       exercising certain other rights of the $2.20 Preferred Stock and to grant
       to the Company the MetLife Louisiana Option (pursuant to which the
       Company has the option to purchase, until February 9, 1997, all shares of
       the $2.20 Preferred Stock and Common Stock held by MetLife Louisiana),
       all in consideration for, among other things, the issuance by the Company
       to MetLife Louisiana of 1,900,075 shares of Common Stock. Such additional
       shares are also subject to the MetLife Louisiana Option. Until June 30,
       1994, the option price is approximately $53.0 million, after giving
       effect to a reduction in the option price for the cash dividend paid on
       the $2.20 Preferred Stock in May 1994. The unexercised option price will
       be increased by 3% on the last day of each calendar quarter until
       December 31, 1995, and by 3 1/2% on the last day of each quarter
       thereafter, and will be reduced by cash dividends paid on the $2.20
       Preferred Stock after February 9, 1994. The Company will be required to
       pay dividends (in either cash or Common Stock) when due on the $2.20
       Preferred Stock in order for the MetLife Louisiana Option to remain
       outstanding. In addition, the MetLife Louisiana Option is subject to
       certain minimum exercise requirements to remain outstanding beyond one
       year and two years; however, even if the net proceeds of the Offering are
       not sufficient to exercise the MetLife Louisiana Option in full, such net
       proceeds will be sufficient to satisfy all of the minimum exercise
       requirements.

Recapitalization, see "Capitalization," "Pro Forma Condensed Consolidated
Financial Data" and Note B of Notes to Consolidated Financial Statements.
 
  Proposed Pipeline Rate Increase
 
     The Company transports its crude oil and a substantial portion of its
refined products utilizing KPL's pipeline and marine terminal facilities in
Kenai, Alaska. In March 1994, KPL filed a revised tariff with the FERC for dock
loading services, which would have increased the Company's annual cost of
transporting products through KPL's facilities from $1.2 million to $11.2
million, or an increase of $10 million per year. Following the FERC's rejection
of KPL's tariff and the commencement of negotiations for the purchase by the
Company of the dock facilities, KPL filed a temporary tariff that would increase
the Company's annual cost by approximately $1.5 million. The negotiations
between the Company and KPL are continuing. The Company believes that the
ultimate resolution of this matter will not have a material adverse effect upon
the financial condition or results of operations of the Company.
 
  Credit Arrangements
 
     During April 1994, the Company entered into a new three-year $125 million
corporate revolving credit facility ("Revolving Credit Facility") with a
consortium of ten banks. The Revolving Credit Facility, which is subject to a
borrowing base, provides for (i) the issuance of letters of credit up to the
full amount of the borrowing base as calculated, but not to exceed $125 million
and (ii) cash borrowings up to the amount of the borrowing base attributable to
domestic oil and gas reserves. Outstanding obligations under the Revolving
Credit Facility are secured by liens on substantially all of the Company's trade
accounts receivable and product inventory and mortgages on the Refinery and the
Company's South Texas natural gas reserves.
 
   
     Letters of credit available under the Revolving Credit Facility are limited
to a borrowing base calculation. As of June 10, 1994, the latest date on which a
borrowing base calculation was made, the borrowing base, which is comprised of
eligible accounts receivable, inventory and domestic oil and gas reserves, was
approximately $95 million. As of June 10, 1994, the Company had outstanding
letters of credit under the new facility of $39 million, with a remaining unused
availability of $56 million. Cash borrowings are limited to the amount of the
oil and gas reserve component of the borrowing base, which has initially been
determined to be
    
 
                                       28
<PAGE>   30
 
approximately $32 million. Cash borrowings under the Revolving Credit Facility
will reduce the availability of letters of credit on a dollar-for-dollar basis;
however, letter of credit issuances will not reduce cash borrowing availability
unless the aggregate dollar amount of outstanding letters of credit exceeds the
sum of the accounts receivable and inventory components of the borrowing base.
The terms of the Revolving Credit Facility include standard and customary
restrictions and covenants. For information concerning such restrictions and
covenants, see Note I of Notes to Consolidated Financial Statements.
 
     The Revolving Credit Facility replaced certain interim financing
arrangements that the Company had been using since the termination of its prior
letter of credit facility in October 1993. The interim financing arrangements
that were cancelled in conjunction with the completion of the new Revolving
Credit Facility included a $30 million reducing revolving credit facility and a
waiver and substitution of collateral agreement with the State. In addition, the
completion of the Revolving Credit Facility provides the Company significant
flexibility in the investment of excess cash balances, as the Company is no
longer required to maintain minimum cash balances or to cash secure letters of
credit.
 
     During May 1994, the National Bank of Alaska and the Alaska Industrial
Development & Export Authority agreed to provide a loan to the Company of up to
$15 million of the $24 million cost of the vacuum unit for the Refinery (the
"Vacuum Unit Loan"). The Vacuum Unit Loan will mature on January 1, 2002, will
require 28 equal quarterly payments beginning April 1, 1995 and will bear
interest at the unsecured 90-day commercial paper rate, adjusted quarterly, 
plus 2.6% per annum for two-thirds of the amount borrowed and at the National 
Bank of Alaska floating prime rate plus 1/4 of 1% per annum for the remainder. 
The Vacuum Unit Loan is secured by a first lien on the Refinery.
 
  Debt and Other Obligations
 
     The Company's funded debt obligations as of December 31, 1993 included
approximately $108.8 million principal amount of Subordinated Debentures, which
bear interest at 12 3/4% per annum and require sinking fund payments sufficient
to annually retire $11.25 million principal amount of Subordinated Debentures.
As part of the Recapitalization, $44.1 million principal amount of Subordinated
Debentures was tendered in exchange for a like principal amount of Exchange
Notes. Such exchange satisfied the 1994 sinking fund requirement and, except for
$.9 million, will satisfy sinking fund requirements for the Subordinated
Debentures through 1997. The indenture governing the Subordinated Debentures
contains certain covenants, including a restriction which prevents the current
payment of cash dividends on Common Stock and currently limits the Company's
ability to purchase or redeem any shares of its capital stock. The Exchange
Notes bear interest at 13% per annum, mature on December 1, 2000 and have no
sinking fund requirements. The limitation on dividend payments included in the
indenture governing the Exchange Notes is less restrictive than the limitation
imposed by the Subordinated Debentures. For further information on restrictions
on dividends, see Note I of Notes to Consolidated Financial Statements. The
Subordinated Debentures and Exchange Notes are redeemable at the option of the
Company at 100% of principal amount, plus accrued interest. The Company is
monitoring the feasibility of a debt offering that would reduce fixed charges by
refinancing all or a substantial portion of such indebtedness at lower interest
rates. The Company is not undertaking such a debt offering at this time because
it considers the current interest rate environment unattractive; however, if
interest rate levels decline, the Company may decide to proceed with such an
offering. There can be no assurance whether or when such an offering would
occur.
 
     If the Subordinated Debentures and the Exchange Notes are redeemed prior to
their respective maturities, the Company will be required to recognize a noncash
extraordinary charge to earnings equal to the portion of the original issue
discount on the Subordinated Debentures and the debt issuance costs of both the
Subordinated Debentures and the Exchange Notes that remains unamortized at the
date of redemption (aggregating approximately $8.5 million at March 31, 1994).
 
     Under an agreement reached in 1993 which settled a contractual dispute with
the State, the Company paid the State $10.3 million in January 1993 and is
obligated to make variable monthly payments to the State through December 2001
based on a per barrel charge on the volume of feedstock processed at the
Refinery that is currently 16 cents and increases to 33 cents. In 1993, the
Company's variable payments to the State
 
                                       29
<PAGE>   31
 
totaled $2.6 million. In January 2002, the Company is obligated to pay the State
$60 million; provided, however, that such payment may be deferred indefinitely
by continuing the variable monthly payments to the State beginning at 34 cents
per barrel for 2002 and increasing one cent per barrel annually thereafter.
 
  Capital Expenditures
 
     The Company has under consideration total capital expenditures ranging from
approximately $65 million to $80 million in 1994. Proposed capital expenditures
for 1994 include approximately $29 million for the continued development of the
Bob West Field, which could be increased by $10 million to $15 million based on
additional development drilling proposed by the operators. In addition, the
proposed capital expenditures for 1994 include $32 million for the refining and
marketing operations, of which $24 million is associated with the installation
of a vacuum unit at the Refinery to allow the Company to further upgrade
residual fuel oil production into higher-valued products. The Revolving Credit
Facility and the Vacuum Unit Loan, along with other available funds, are
expected to provide sufficient capital to meet the Company's capital expenditure
requirements during 1994.
 
  Cash Flows From Operating, Investing and Financing Activities
 
     During the three months ended March 31, 1994, cash and cash equivalents
increased by $12.8 million and short-term investments decreased by $6.0 million.
At March 31, 1994, the Company's cash totaled $49.4 million, which included
$26.6 million as collateral for outstanding letters of credit. Subsequent to
March 31, 1994, these interim cash-backed letter of credit arrangements were
replaced by the Revolving Credit Facility (see Note I of Notes to Consolidated
Financial Statements). Working capital amounted to $110.3 million at March 31,
1994. Net cash from operating activities of $30.3 million during the three
months ended March 31, 1994, compared to $14.4 million for the 1993 quarter, was
primarily due to net earnings adjusted for certain noncash charges and reduced
working capital requirements. The 1993 quarter included a payment of $10.8
million to the State in connection with the settlement of a contractual dispute.
Net cash used in investing activities of $10.2 million during the three months
ended March 31, 1994 included capital expenditures of $18.5 million, partially
offset by cash proceeds of $2.0 million from the sale of the Company's Valdez,
Alaska terminal and the sale of $6.0 million in short-term investments. Capital
expenditures for the three months ended March 31, 1994 included $11.7 million
for exploration and production activities in the Bob West Field, where an
additional six natural gas development wells were completed during this period.
The refining and marketing segment's capital expenditures totaled $6.1 million
for the three months ended March 31, 1994, primarily for initial installation
costs for the vacuum unit and completion of the deisobutanizer unit. Net cash
used in financing activities of $7.3 million during the three months ended March
31, 1994 included the repayment of net borrowings of $5.0 million under the
reducing revolving credit facility, which was replaced by the Revolving Credit
Facility (see Note I of Notes to Consolidated Financial Statements).
 
     During 1993, cash and cash equivalents decreased by $10.3 million and
short-term investments decreased by $14.1 million. At December 31, 1993, the
Company's cash and short-term investments totaled $42.5 million, which included
restricted funds of $25.4 million as collateral for outstanding letters of
credit. Working capital amounted to $124.5 million at December 31, 1993. Net
cash from operating activities of $19.5 million in 1993 was primarily due to net
earnings adjusted for certain noncash charges, partially offset by payments
totaling $12.9 million to the State under the settlement agreement entered into
in January 1993 and increased working capital requirements. Net cash used in
investing activities of $23.5 million during 1993 included capital expenditures
of $37.5 million, mainly for exploration and development activities in the Bob
West Field. During 1993, the Company completed the expansion of a gas processing
facility and pipeline and drilled 15 development gas wells in this field. In
addition, the Company participated in drilling four exploratory wells and one
development well outside of the Bob West Field in 1993. These uses of cash in
investing activities were partially offset by the net decrease of $14.1 million
in short-term investments. Net cash used in financing activities of $6.3 million
in 1993 included the repurchase of $11.25 million principal amount of
Subordinated Debentures for $9.7 million in cash, partially offset by borrowings
of $5.0 million under the reducing revolving credit facility, which has since
been replaced. The Company did not pay dividends on preferred stocks in 1993,
 
                                       30
<PAGE>   32
 
which resulted in cumulative dividend arrearages of $28.7 million at December
31, 1993. Such dividend arrearages have since been satisfied by consummation of
the Recapitalization. As a result of the Recapitalization, annual preferred
stock dividend requirements have been reduced to $6.3 million; such dividend
requirements will be eliminated if the MetLife Louisiana Option is exercised in
full.
 
     During 1992, cash and cash equivalents decreased by $14.2 million and
short-term investments increased by $20.0 million. Cash flows from operating
activities of $11.4 million included a net loss, offset by certain significant
noncash charges, including the cumulative effect of accounting changes,
depreciation, depletion and amortization and the settlement with the State, and
by reduced working capital requirements. Net cash used in investing activities
of $21.1 million in 1992 was mainly due to capital expenditures of $15.4
million, primarily for continued exploration and development activities in the
Bob West Field and capital improvements in Alaska, and to the purchase of
short-term investments of $24.0 million. During 1992, the Company began
investing in short-term debt securities with original maturities in excess of 90
days. These investments are classified as short-term investments on the
Consolidated Balance Sheets. Partially offsetting cash used in investing
activities in 1992 were net proceeds of $12.9 million from sales of assets.
During 1992, the Company received, before expenses, $6.8 million for the sale of
the Company's Indonesian operations, $3.3 million for the sale of the corporate
aircraft and related assets and $2.1 million for the sale of certain exploration
and production properties outside of the Bob West Field. Cash flows used in
financing activities of $4.5 million in 1992 included the repayment of $6.5
million of long-term debt, primarily related to borrowings under a secured
financing agreement for development of natural gas reserves in the Bob West
Field. This financing arrangement, under which the Company borrowed $2.0 million
in 1992, was terminated by the Company in December 1992. The Company deferred
payments of dividends on preferred stocks in 1992.
 
     During 1991, cash and cash equivalents decreased $16.1 million. Cash flows
from operating activities of $17.9 million included net earnings of $3.9
million, partially offset by a $5.2 million payment to the Department of Energy.
Net cash used in investing activities of $24.7 million in 1991 was primarily
comprised of capital expenditures for exploration and development activities in
the Bob West Field and capital improvements in Alaska. Cash flows used in
financing activities of $9.3 million in 1991 were primarily for dividend
payments on preferred stocks for three and one-half quarters, which totaled $8.0
million.
 
     For further information concerning actions recently taken by Tennessee Gas
under the Tennessee Gas Contract and the potential effect thereof on the
Company's income and cash flows from operating activities, see "-- Results of
Operations -- Exploration and Production -- Three Months Ended March 31, 1994
Compared to Three Months Ended March 31, 1993."
 
LITIGATION
 
     The Company is subject to certain commitments and contingencies, including
a contingency relating to a natural gas sales contract dispute with Tennessee
Gas. The Company is selling a portion of the gas from its Bob West Field to
Tennessee Gas under a Gas Purchase and Sales Agreement which provides that the
price of gas shall be the maximum price as calculated in accordance with Section
102(b)(2) (the "Contract Price") of the Natural Gas Policy Act of 1978 (the
"NGPA").
 
     Tennessee Gas filed suit against the Company alleging that the gas contract
is not applicable to the Company's properties and that the gas sales price
should be the price calculated under the provisions of Section 101 of the NGPA
rather than the Contract Price. During March 1994, the Contract Price was $7.84
per Mcf, the Section 101 price was $4.58 per Mcf and the average spot market
price was $2.09 per Mcf. Tennessee Gas also claimed that the contract should be
considered an "output contract" under Section 2.306 of the Texas Business and
Commerce Code and that the increases in volumes tendered under the contract
exceeded those allowable for an output contract. The Company continues to
receive payment from Tennessee Gas based on the Contract Price for all volumes
that are subject to the contract under the Company's interpretation.
 
     The District Court trial judge returned a verdict in favor of the Company
on all issues. On appeal by Tennessee Gas, the Court of Appeals affirmed the
validity of the Tennessee Gas Contract as to the Company's properties and held
that the price payable by Tennessee Gas for the gas was the Contract Price. The
Court of
 
                                       31
<PAGE>   33
 
Appeals remanded the case to the trial court based on its determination (i) that
the Tennessee Gas Contract was an output contract and (ii) that a fact issue
existed as to whether the increases in the volumes of gas tendered to Tennessee
Gas under the contract were made in bad faith or were unreasonably
disproportionate to prior tenders. The Company is seeking review of the
appellate court ruling on the output contract issue in the Supreme Court of
Texas. Tennessee Gas is seeking review of the appellate court ruling denying the
remaining Tennessee Gas claims in the Supreme Court of Texas.
 
     Although the outcome of any litigation is uncertain, management, based upon
advice from outside legal counsel, is confident that the decision of the trial
and appellate courts will ultimately be upheld as to the validity of the
Tennessee Gas Contract and the Contract Price. Therefore, if the Supreme Court
of Texas does not grant the Company's petition for writ of error and affirms the
appellate court ruling, the Company believes that the only issue for trial
should be whether the increases in the volumes of gas tendered to Tennessee Gas
from the Company's properties were made in bad faith or were unreasonably
disproportionate. The appellate court decision was the first reported decision
in Texas holding that a take-or-pay contract was an output contract. As a
result, it is not clear what standard the trial court would be required to apply
in determining whether the increases were in bad faith or unreasonably
disproportionate. The appellate court acknowledged in its opinion that the
standards used in evaluating other kinds of output contracts would not be
appropriate in this context. The Company believes that the appropriate standard
would be whether the development of the field was undertaken in a manner that a
prudent operator would have undertaken in the absence of an above-market sales
price. Under that standard, the Company believes that, if this issue is tried,
the development of its gas properties and the resulting increases in volumes
tendered to Tennessee Gas will be found to have been reasonable and in good
faith. Accordingly, the Company has recognized revenues, net of production taxes
and marketing charges, for natural gas sales through March 31, 1994, under the
Tennessee Gas Contract based on the Contract Price, which net revenues
aggregated $21.1 million more than the Section 101 prices and $38.9 million in
excess of the spot market prices. If Tennessee Gas ultimately prevails in this
litigation, the Company could be required to return to Tennessee Gas the
difference between the spot market price for gas and the Contract Price, plus
interest, if awarded by the court. In addition, the present value of estimated
future net revenues on a pre-tax basis from the Company's proved domestic
reserves has been calculated based in part on the price being paid by Tennessee
Gas at the date of determination. At March 31, 1994, such present value was
$171.0 million. If calculated using March 31, 1994 spot market prices instead of
the Contract Price, such present value would have been $92.0 million.
 
   
     On June 7, 1994, Tennessee Gas filed a motion with the court requesting
that the court permit Tennessee Gas to pay the difference between the Contract
Price and the spot market price into the registry of the court on a monthly
basis in lieu of paying the Company the Contract Price or, in the alternative,
that the court require the Company to post a bond to secure any amount which the
Company might owe Tennessee Gas if Tennessee Gas were to ultimately prevail in
the litigation. The Company believes that Tennessee Gas is not entitled to avoid
paying the Contract Price by such monthly payments but that Tennessee Gas may be
able to cease making payments above spot market prices pending the ultimate
outcome of the litigation if it posts a satisfactory bond. The Company does not
believe that the court will require the Company to post a bond. If the court
were to permit Tennessee Gas to reduce its payments to the Company to spot
market prices pending resolution of the litigation, the Company's cash flow
would be substantially reduced. The Company believes that at present spot market
prices the Company would be able to fund its capital expenditure program and
comply with its financial covenants under the Revolving Credit Facility if the
court were to grant the request of Tennessee Gas.
    
 
   
     An adverse judgment in this case could have a material adverse effect on
the Company. See "Legal Proceedings -- Tennessee Gas Contract" and Notes K and P
of Notes to Consolidated Financial Statements.
    
 
ENVIRONMENTAL
 
     The Company is subject to extensive federal, state and local environmental
laws and regulations. These laws, which are constantly changing, regulate the
discharge of materials into the environment and may require the Company to
remove or mitigate the environmental effects of the disposal or release of
petroleum or chemical substances at various sites or install additional controls
or other modifications or changes in use for
 
                                       32
<PAGE>   34
 
certain emission sources. The Company is currently involved in remedial
responses and has incurred cleanup expenditures associated with environmental
matters at a number of sites, including certain of its own properties. Although
the level of future expenditures for environmental purposes, including cleanup
obligations, is impossible to determine with any degree of probability, it is
management's opinion that, based on current knowledge and the extent of such
expenditures to date, the ultimate aggregate cost of environmental remediation
will not have a material adverse effect on the Company's financial condition. At
March 31, 1994, the Company's accrual for environmental liabilities was $6.0

IMPACT OF CHANGING PRICES
 
     The Company's operating results and cash flows are sensitive to the
volatile changes in energy prices. Major shifts in the cost of crude oil and the
price of refined products can result in a change in gross margin from the
refining and marketing operations, as prices received for refined products may
or may not keep pace with changes in crude costs. These energy prices, together
with volume levels, also determine the carrying value of crude oil and refined
product inventory.
 
     Likewise, major changes in natural gas prices impact revenues and the
present value of estimated future net revenues from the Company's exploration
and production operations. The carrying value of oil and gas assets may also be
subject to noncash write-downs based on changes in natural gas prices and other
determining factors. See "Investment Considerations -- Uncertainty in Estimating
Oil and Gas Reserves."

GENERAL
 
     The Company is an independent energy company engaged in refining and
marketing, primarily in Alaska, and in the exploration for and production of
natural gas and crude oil in South Texas and Bolivia. The Company also markets
lubricants, fuels and specialty petroleum products on a wholesale basis. For
financial information relating to industry segments, see "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and

REFINING AND MARKETING
 
  Refining and Marketing Activities
 
     Industry Overview/Competition. The refining and marketing businesses are
highly competitive, with price being the principal factor in competition. In the
refining market, the Company competes primarily with three other refineries in
Alaska and, to a lesser extent, refineries on the West Coast. Given the
Refinery's proximity to the Alaskan market, the Company believes it enjoys a
cost advantage in that market versus refineries on the West Coast. However,
there is no assurance that the Company's cost advantage can be maintained. The
Company's refining competition in Alaska consists of a refinery situated near
Fairbanks owned by MAPCO, Inc. and two refineries situated near Valdez and
Fairbanks, respectively, owned by Petro Star Inc. The Company estimates that
such other refineries have a combined capacity to process approximately 156,000
BPD of crude oil. ANS crude oil is the only feedstock used in these competing
refineries. After processing the crude oil and removing the lighter-end
products, which represent approximately 30% of each barrel processed, these
refiners are permitted, because of their direct connection to the TAPS, to
return the remainder of the residual products back into the pipeline system as
"return oil" in consideration for a fee, thereby eliminating their need to
market residual products. The Refinery is not directly connected to the TAPS,
and the Company, therefore, cannot return its residual products to the TAPS. In
general, the competing refineries in Alaska do not have the same downstream
capabilities that the Company currently possesses. Management of the Company
estimates that the Company has the capacity to produce approximately twice the
volume of light products per barrel of ANS crude oil that any of the competing
refineries is currently able to produce.
 
     The Company's marketing business in Alaska is segmented by product line.
The Company believes it is the largest producer and distributor of gasoline in
Alaska, with the largest network of branded and unbranded dealers and jobbers.
The Company is the principal supplier for two major oil companies through
product exchange agreements, whereby gasoline in Alaska is provided in exchange
for gasoline delivered to the Company on the West Coast. Jet fuel sales are
concentrated in Anchorage, where the Company is one of two principal suppliers
to, and the only supplier with a direct pipeline into, the Anchorage
International Airport, which is a major hub for air cargo traffic to the Far
East. Diesel fuel is sold primarily on a wholesale basis.
 
     The Company's West Coast marketing business is primarily a distribution
business selling to independent dealers and jobbers outside major urban areas.
The Company competes against independent marketing companies and, to a lesser
extent, integrated oil companies when engaging in these marketing operations.
 
     The Kenai Refinery. The Company's Refinery is strategically located in
Kenai, Alaska, approximately 90 miles southwest of Anchorage, Alaska, where it
has access to multiple sources of crude oil. The original crude oil distillation
unit was built by Tesoro in 1969 with a capacity of 17,500 BPD. The crude unit
was originally designed to process Cook Inlet crude oil, as the Alaskan North
Slope had not yet been developed. During the 1970s and 1980s, the crude unit was
updated and expanded to its current capacity of 72,000 BPD. These expansions
enabled the Company to process 100% ANS crude oil. In addition, the Company has,
over time, added numerous downstream processing units, including a hydrocracker,
a deisobutanizer ("DIB") unit, a reformer, a Partial Recycle Isomerization
Process ("PRIP") unit, and during 1994 will add automated process controls. The
Company has received permits and has begun construction on a new vacuum unit,
which is expected to begin operating in January 1995.

     Crude Oil Supply. The Refinery is designed to process crude oil with up to
1.0% sulphur content. As such, the Refinery can process Cook Inlet, ANS and
certain foreign crude oils.
 
          ANS Crude Oil. ANS crude oil is a heavy crude oil which contains an
     average of 1.0% sulphur. In 1993, approximately 72% (35,600 BPD) of the
     Refinery's feedstock was ANS crude oil, of which approximately 24,300 BPD
     was purchased under a royalty crude oil purchase contract with the State,
     which is scheduled to expire at the end of 1994. The Company and the State
     have agreed in principle to extend the contract through 1995. During 1994,
     this contract requires the Company to purchase approximately 27,500 BPD of
     ANS crude oil. The agreement in principle between the Company and the State
     would require the Company to purchase approximately 40,000 BPD during 1995.
     The Company does not currently anticipate increasing the percentage of ANS
     crude oil utilized as feedstock at the Refinery. Under its agreement in
     principle with the State, the Company has the right to sell or to exchange
     up to 20% of the ANS crude oil to be purchased from the State during 1995.
     The Company's additional ANS crude feedstock supply is currently purchased
     pursuant to a short-term contract.
 
          Cook Inlet Crude Oil. Cook Inlet crude oil, a lighter crude oil that
     contains an average of .1% sulphur, accounted for approximately 22% of the
     Refinery's feedstock supply in 1993. The Company obtains Cook Inlet crude
     from several producers on the Kenai Peninsula under short-term contracts.
 
          Other Supply. In 1993, the Refinery obtained approximately 6% of its
     feedstock supply from other sources. This feedstock supply was primarily
     heavy atmospheric gas oil ("HAGO") and was purchased from a local
     competitor's refineries and from a West Coast refinery under short-term
     contracts. HAGO is a refinery byproduct which generates various light
     refined products with no residual fuel oil.
 
   
     Transportation of Crude Oil Supply. The ANS crude oil is transported by the
TAPS from the North Slope to Valdez, Alaska. From Valdez, the Company charters
an American flag vessel, the Overseas Washington, under an agreement expiring in
October 1994, to transport ANS crude oil from the TAPS terminal at Valdez,
Alaska to the Refinery. The Company has recently completed negotiations for a
replacement vessel which will commence transporting ANS crude oil from the TAPS
terminal at Valdez to the Refinery beginning in November 1994. A central
gathering system collects Cook Inlet crude oil for pipeline transport to the
Refinery.
    
 
     Alaskan Refinery Products and Marketing. The Company is a major supplier of
petroleum products within Alaska, the primary marketplace for the Company's
refined products. In 1993, Refinery production was approximately 25% jet fuel,
25% gasoline, 14% other distillates, including diesel fuel, and 36% residual
fuel oil. The Company has implemented a market-driven strategy which has
resulted in significant changes in the operation of the Refinery, including: (i)
a reduction in Refinery throughput from approximately 61,000 BPD in 1992 to
approximately 50,000 BPD in 1993 to better align Refinery production with
refined product demand in the Alaskan market and (ii) a reduction in the
percentage of Refinery feedstocks represented by heavier ANS crude oil, which
resulted in the reduction in the percentage of residual fuel oil produced. In
addition, the Company focused on the marketing of residual fuel oil primarily as
a feedstock for West Coast refineries. Changes in the Company's sales prices to
such refineries can be linked to changes in crude oil prices, unlike the more
volatile Far Eastern bunker fuel markets where the Company had primarily
marketed its residual fuel oil in the past.

</TABLE>
 
     Gasoline. In 1993, the Company distributed approximately 89% of the
gasoline produced at the Refinery to end users in Alaska, by retail sales
through 33 of its 7-Eleven convenience stores and two other locations, by
wholesale sales through 68 branded and 25 unbranded dealers and jobbers and by
deliveries to two major oil companies for their retail operations in Alaska in
exchange for gasoline delivered to the Company in the West Coast market. During
1993, the production of gasoline by all refineries in Alaska, including the
Company's, exceeded the market demand. As a result, the remaining approximately
11% of the Refinery's 1993 gasoline production was transported to West Coast
markets. These export sales are generally made during the winter months when the
demand for gasoline in Alaska is lowest.
 
     Jet Fuel. The Company is a major supplier of commercial jet fuel into the
Alaskan marketplace, with all of its production being marketed in Alaska to
passenger and cargo airlines. The demand for jet fuel in Alaska currently
exceeds the production of the refiners in Alaska, and several marketers,
including the Company, import jet fuel into Alaska to meet excess demand.
 
     Diesel Fuel and Other Distillates. Substantially all of the Company's
diesel fuel and other distillate production is sold on a wholesale basis in
Alaska and resold primarily for marine and industrial purposes. Approximately 5%
of the Company's diesel fuel production in 1993 was sold for on-highway use.
Generally, the production of diesel fuel in Alaska is in balance with demand;
however, because of the high variability of the demand, there are occasions when
diesel fuel is imported into or exported from Alaska.
 
     Residual Fuel Oil. Due to the Refinery's configuration, a product of the
Company's refining process is residual fuel oil. Since there is no significant
demand for residual fuel oil in Alaska, substantially all of the Company's
residual fuel oil production is exported from Alaska. During 1993, pursuant to
its new marketing strategy, the Company commenced selling and transporting a
substantial volume of its residual fuel oil to the
 
                                       36
<PAGE>   38
 
West Coast, where it is generally used as a refinery feedstock. Prior to 1993,
the Company's primary market for the residual fuel oil was the Far Eastern
bunker fuel markets. Marketing the residual fuel oil as a feedstock has, to a
significant degree, reduced the Company's exposure to the pricing volatility
that exists in the Far Eastern bunker fuel markets. In addition, the Refinery's
reduced throughput and reduction of ANS crude oil as a percentage of total
feedstock has caused residual fuel oil output to decrease from approximately
23,400 BPD in 1992 to approximately 17,600 BPD during 1993. The installation of
the vacuum unit is expected to further reduce the production of residual fuel
oil significantly and improve the Company's overall product mix.
 
     West Coast Marketing. In support of the Refinery, the Company conducts
domestic wholesale marketing operations, primarily in California, Oregon and
Washington. During 1993, these operations sold approximately 27,800 BPD of
refined products, of which approximately 30% was received from major oil
companies in exchange for products from the Refinery, approximately 5% was
received directly from the Refinery and the balance was purchased from other
suppliers. The Company sells these refined products in the bulk market and
through 25 terminal locations, of which four are owned by the Company.
 
     Refined Product Transportation. The Company operates a ten-inch diameter
common carrier petroleum pipeline from the Refinery to its terminal in
Anchorage. The pipeline allows the Company to transport light products to the
terminal throughout the year, regardless of weather conditions. During 1993, the
pipeline transported an average of approximately 22,300 BPD of petroleum
products, all of which were transported for the Company. The pipeline has a
capacity of 40,000 BPD. From the Company's Anchorage terminal, light petroleum
products are distributed by contracted jobbers to 33 of the Company's 7-Eleven
stores and two other locations, 68 branded and 25 unbranded dealers and two
major oil companies. The Company also has a charter for an American flag vessel,
the Baltimore Trader, under an agreement expiring in July 1994 with a six-month
renewal option remaining. The Baltimore Trader is used primarily to transport
residual fuel oil to California and occasionally to transport feedstocks to the
Refinery. With the installation of the vacuum unit at the Refinery and the
resultant further decrease in residual fuel oil production, the Company
anticipates that the vessel replacing the Overseas Washington will also be able
to meet the Company's residual fuel oil transportation needs after the Baltimore
Trader charter expires. See "--Transportation of Crude Oil Supply." From time to
time, the Company also charters tankers and ocean-going barges to transport
petroleum products to its customers within Alaska, on the West Coast and in the
Far East.
 
     For further information on transportation in Alaska, see "Government
Regulation and Legislation -- Environmental Controls."
 
     Capital Expenditure Program. The Company has under consideration total
capital expenditures for the refining and marketing operations of $32 million in
1994, of which $24 million is associated with the installation of a vacuum unit
at the Refinery. Under the Vacuum Unit Loan, the Company may borrow up to $15
million of the $24 million cost of the vacuum unit. See "Management's Discussion
and Analysis -- Capital Resources and Liquidity." Approximately $5 million is
planned to be expended in 1994 on 7-Eleven store upgrades, the opening of new
7-Eleven stores and continued upgrading of underground storage tanks in the
Alaskan retail operations. The remainder of the refining and marketing capital
expenditures is primarily related to normal Refinery maintenance.
 
     Refinery Units. The following is a flow chart of the Refinery's major
process units and a summary description of the Refinery's process units and
their respective functions.

<PAGE>   40
 
     Crude Unit. The crude unit was built in 1969 and has been modified twice,
most recently during 1983-1985. After expansion and modification, the Refinery
has a rated capacity of 72,000 BPD. The hydrocarbon compounds that make up crude
oil separate or "fractionate" when subjected to high temperatures. The crude
unit fractionates crude oil into finished products (jet fuel and diesel fuel)
and feedstock for further processing (liquefied petroleum gas ("LPG") and off
gas, light straight run, heavy naphtha, atmospheric gas oil and atmospheric
residuum). The LPG and off gas are further processed in the amine and LPG units.
The light straight run is pumped to the PRIP unit for further processing. The
heavy naphtha is feedstock for the reformer. The atmospheric gas oil is further
processed in the hydrocracker. The remaining atmospheric residuum is currently
sold as feedstock to complex refineries on the West Coast.
 
     Vacuum Unit. A 16,500 BPD vacuum unit is currently being installed and is
scheduled to commence operations in January 1995. Residual fuel oil is used for
feedstock for the vacuum unit. In the vacuum unit, the residual fuel oil is
fractionated into three different products: (i) Light Vacuum Gas Oil ("LVGO"),
(ii) Heavy Vacuum Gas Oil ("HVGO") and (iii) Vacuum Tower Bottom ("VTB").
 
     The LVGO is further processed in the hydrocracker and converted into
gasoline and jet fuel. HVGO is sold to refineries on the West Coast for
catalytic hydrocracker feedstock. VTB's are blended with light cycle oil to
produce bunker fuel, which is sold primarily on the West Coast.
 
     Deisobutanizer Unit. A 5,000 BPD DIB unit came on stream in December 1993.
With the addition of the DIB unit, the Refinery is able to produce high purity
(95%) normal butane for gasoline blending and to also increase the production of
propane (150 BPD). Tesoro previously blended a mixture of isobutane and normal
butane into gasoline. The isobutane/normal butane mixture has a higher vapor
pressure than normal butane. With the production of normal butane from the DIB
unit, Tesoro is able to increase the amount of normal butane used in gasoline
blending, which results in increased gasoline production of approximately 600
BPD.
 
     Hydrocracker Unit. The 9,000 BPD hydrocracker unit was installed in 1981
and upgraded during the Refinery's modification in 1983-1985. The hydrocracker
unit processes atmospheric gas oil from the crude unit, combined with hydrogen
from the reformer and the hydrogen plant, into jet fuel and feedstock (heavy
hydrocrackate, light hydrocrackate and LPG and off gas).
 
     Reformer. The reformer, which has a 12,000 BPD capacity, was constructed in
1975 and upgraded in 1980. The unit is fed naphtha from the crude unit and heavy
hydrocrackate from the hydrocracker unit. These are converted into high octane
reformate for gasoline blending. Other products from the reformer are hydrogen,
which is used in the hydrocracker unit, LPG, which is feedstock for the LPG
unit, and off gas, which is used as fuel for the process heaters at the
Refinery.
 
     Partial Recycle Isomerization Process Unit. The light straight run gasoline
from the crude unit and the light hydrocrackate from the hydrocracker unit are
the feedstocks for this unit. The PRIP unit produces a stream of isomerate which
is used to increase the octane of gasoline. The PRIP unit allows Tesoro to make
100% unleaded and super unleaded gasoline and at the same time reduce the
percentage of aromatic hydrocarbons in the finished gasoline product. This unit
was installed in 1986 and has a capacity of 4,000 BPD.
 
     Amine Unit. The Company's amine unit was constructed in 1981 and reworked
in 1985. It has a capacity of 2,500 BPD. The amine unit removes hydrogen sulfide
from LPGs and off gases produced in other units. The off gases are used as fuel
for the process heaters and the LPG is feedstock for the LPG unit.
 
     Sulphur Plant. The sulphur plant processes the hydrogen sulfide from the
amine unit into sulphur.
 
     LPG Unit. The 2,400 BPD LPG unit was built in 1975. The unit produces
finished product (commercial grade propane) and feedstock (a butane-plus product
that is used for gasoline blending and as refinery fuel).
 
     Operations. Each unit in the Refinery requires regular maintenance and
repair (referred to as "turnarounds") during which it is not in operation.
Turnaround cycles vary for different units and, in general, the Refinery
managers plan product inventories and unit maintenance to permit some operations
to continue even when certain units are inactive. Maintenance turnarounds
involve a number of independent contractors and engineers, as well as the
Refinery's own personnel. Turnarounds are effected on a continuous 24-hour basis
in order to minimize the unproductive time of the units involved. Tesoro
expenses current maintenance charges
 
                                       39

as incurred and estimated amounts related to the future expenses of periodic
process unit turnarounds. At the time such periodic unit turnarounds are
performed, the actual costs incurred are charged against the previously
established liabilities. To the extent actual costs exceed previously
established liabilities, a turnaround may result in reduced income. The Company
completed a turnaround of the crude unit in May 1992 and anticipates another
turnaround in September 1994. The Company is planning a turnaround of the
hydrocracker in 1996, a turnaround of the reformer in 1994 and a turnaround of
the PRIP unit in 1995.
 
EXPLORATION AND PRODUCTION
 
  South Texas
 
     Since 1989, Tesoro's exploration staff has generated numerous exploration
prospects in the Wilcox Trend of South Texas. The Wilcox Trend extends from
Northern Mexico through South Texas into Western Louisiana. Multiple pay sands
exist within the Wilcox Trend, where extensive faulting has trapped hydrocarbons
in numerous producing zones. The Company's South Texas exploration program has
been very successful as a result of the discovery of the Bob West Field, with
the Company having achieved an average finding cost of $.43 per Mcf of gas
during the period beginning October 1, 1990 and ending December 31, 1993. In
April 1992, Tesoro sold its interest in all producing and undeveloped properties
in South Texas outside the Bob West Field in order to concentrate its resources
on the Bob West Field.
 
     The Bob West Field is located in the southern part of the Wilcox Trend in
Starr and Zapata Counties. The field represents a major gas discovery with
estimated ultimately recoverable gross proved reserves of 334 Bcf of natural
gas, of which approximately 56 Bcf had been produced through March 31, 1994.
Tesoro owns an average 50% revenue interest in approximately two-thirds of the
Bob West Field and an average 28% revenue interest in the remaining one-third.
There are 23 known productive sands in the Bob West Field, 17 of which are now
producing. The producing sands are found at depths of approximately 8,000 to
16,000 feet. The Bob West Field encompasses approximately 4,000 acres, and the
thickness of individual productive zones ranges from 20 feet to as much as 220
feet. Continued successful development of the Bob West Field has resulted in an
increase in Tesoro's net proved domestic natural gas reserves from 74 Bcf at
year end 1992 to 120 Bcf at year end 1993, which represents an increase of
approximately 63%. During December 1993, the Company's net production from the
Bob West Field averaged 58 MMcf of gas per day, representing a 222% increase
over the December 1992 production level of 18 MMcf of gas per day. Fifteen
development wells were drilled and completed in the Bob West Field during 1993,
at a cost to the Company of approximately $21.4 million. Through year end 1993,
the Company has successfully completed a total of 25 wells within the Bob West
Field, with no dry holes encountered in the process. The Company's development
program for 1994 and 1995 provides for the drilling of ten and five wells,
respectively, on the two producing acreage units within the Bob West Field that
are subject to the Tennessee Gas Contract and 17 and 10 wells, respectively, on
other acreage within the Bob West Field. In the first quarter of 1994, six wells
were drilled. The net costs associated with the Company's 1994 drilling program
(including the wells drilled during the first quarter) are expected to be
approximately $41.4 million.
 
     The Company has entered into an agreement (the "Co-Operator Agreement")
pursuant to which the Company acts as the geological operator of approximately
two-thirds of the Bob West Field (the "Co-Operator Portion"), while Coastal Oil
& Gas Corporation acts as the production operator. As geological operator,
Tesoro's responsibilities include: (i) proposing and conducting seismic
operations, (ii) soliciting, evaluating and awarding bids for electric and mud
logging and (iii) assimilating subsurface information from each drill site and
applying such information for purposes of continuing development of the
Co-Operator Portion. In addition, the Company has proposed the drilling of all
new wells and the surface and subsurface location of such wells in the
Co-Operator Portion. The Company continues to propose the drilling of all new
wells in the Co-Operator Portion, but as of December 1, 1993 no longer has the
exclusive right to do so. The production operator is responsible for all other
operations associated with the Co-Operator Portion, including the drilling,
completion and production of all wells.
 
     Upon the expiration of the Co-Operator Agreement on December 3, 1994, the
Company has the option of assuming responsibility for the production operator's
duties in the Co-Operator Portion. This option is
 
                                       40
<PAGE>   42
 
contingent upon the Company's demonstrating to the production operator that the
Company has an in-house engineering staff and field operations staff capable of
and experienced in producing and reworking high pressure gas wells. The Company
believes that it will satisfy this requirement when the Co-Operator Agreement
expires, and currently intends to exercise the option to assume the production
operator's responsibilities for the Co-Operator Portion.
 
     During 1993, in addition to the continued development of the Bob West
Field, the Company participated in the drilling of four exploratory wells at a
net cost of approximately $1.7 million in other areas of the Wilcox Trend. One
exploratory well was completed as a gas well and is currently producing, one has
been completed and is awaiting a pipeline connection and two were dry holes. In
1994, a delineation well to the first exploratory discovery was drilled at a net
cost of approximately $.2 million and was evaluated as a dry hole. Another
exploratory well drilled during 1994 has been completed but has not been tested.
Management of the Company currently intends to recommend to the Company's Board
of Directors that the Company proceed with a limited exploration program focused
primarily on the Wilcox Trend of South Texas if the Offering is successfully
completed and the MetLife Louisiana Option is exercised in full.
 
     Tennessee Gas Contract. The Company has interests in two 352-acre producing
units in the Bob West Field that are subject to a gas purchase contract with
Tennessee Gas expiring on January 31, 1999. The Tennessee Gas Contract requires
Tennessee Gas to purchase gas from the two producing units at escalating prices
that are substantially above current spot market prices for natural gas. During
1993, for example, Tennessee Gas purchased approximately 27% of the Company's
net gas production from the Bob West Field under the Tennessee Gas Contract at
an average price of $7.59 per Mcf of gas, which was substantially above the 1993
average spot market rate of $2.03 per Mcf. The Tennessee Gas Contract is
presently the subject of litigation with Tennessee Gas. See "Investment
Considerations," "Legal Proceedings -- Tennessee Gas Contract" and Notes K and P
of Notes to Consolidated Financial Statements.
 
     Gas Processing, Gathering and Transportation. The Company owns a 70%
interest in the central gas processing facility for the Bob West Field, which is
currently capable of processing 120 MMcf per day. The Company also owns a 70%
interest in the Starr County Gathering System's two 10-inch diameter pipelines.
The pipelines transport the Company's gas production eight miles to a 16-inch
diameter pipeline from the Bob West Field. In February 1994, the pipeline
facilities were at capacity and production subject to spot market prices was
being curtailed. However, the Company has continued to produce and transport all
of its gas in the Bob West Field subject to the Tennessee Gas Contract. New
common carrier pipeline facilities have been constructed by Coastal States Gas
Transmission Company. The Company believes the new facilities should provide
adequate transportation for all of the Company's gas production from the Bob
West Field. Tesoro has exercised its option to acquire a 50% interest in the new
pipeline facilities in consideration for payment of 50% of the capitalized costs
attributable to the facilities, plus interest on such costs at the rate of 8%
per annum. In addition, the central gas processing facility and sales line are
currently being expanded to enable processing in excess of 150 MMcf per day.
 
     The Company does not operate the central gas processing facility for the
Bob West Field or the Starr County Gathering System's two 10-inch diameter
pipelines. If the Company is appointed as or becomes the production operator or
sole operator of the Co-Operator Portion under the Co-Operator Agreement, the
Company will be appointed as the operator of the central gas processing facility
for the Bob West Field. See " -- South Texas."

  Bolivia
 
   
     The Company's Bolivian exploration and production operations are located in
southern Bolivia near the border of Argentina, where, since 1976, the Company
has discovered four significant natural gas fields. As of December 31, 1993,
Tesoro was the second largest holder of proved natural gas reserves in Bolivia,
with estimated net proved reserves totaling 112 Bcfe. The Company is the
operator of a joint venture that holds two Contracts of Operation with YPFB, the
Bolivian state-owned oil and gas company. The Company has a 75% interest in a
Contract of Operation, which expires in 2007, covering approximately 93,000
acres in Block XVIII. The Company has drilled five exploratory wells and 12
development wells within three separate fields in Block XVIII. During 1993, the
Company's net production averaged 19 MMcf of gas per day and 660 Bbls of
condensate per day, a production level that has been maintained for more than
three years. The Company and its joint venture participant are entitled to
receive a quantity of hydrocarbons equal to 40% of the total production, net of
Bolivian taxes on production (which are payable in kind), with YPFB receiving
the remainder. Under the sales contract with YPFB covering hydrocarbons produced
from the La Vertiente, Escondido and Taiguati Fields in Block XVIII, the Company
and its joint venture participant have contracted to sell approximately 18 MMcf,
after Bolivian taxes, of natural gas per day to YPFB, which in turn resells the
gas to the Republic of Argentina. At December 31, 1993, the Company was
receiving $1.25 per Mcf for gas sold under this contract. The contract between
YPFB and the Republic of Argentina has recently been extended for an additional
three-year period ending March 31, 1997. The contract extension will maintain
approximately the same volumes, but with a small decrease in price. The
Company's contract with YPFB, including the pricing provision, is presently
subject to renegotiation for up to a three-year period. The Company expects such
renegotiation with YPFB to commence in July 1994. As a result of the terms of
the contract extension between YPFB and the Republic of Argentina, the Company
expects the renegotiation to result in a corresponding small decrease in the
contract price. The renegotiation could also result in a reduction of volumes
purchased from the Company due to new supply sources anticipated to commence
producing near the end of 1994.
    
 
     The Company has a 72.6% interest in a Contract of Operation, which expires
in 2008, covering approximately 1.2 million acres in Block XX. The Company and
its joint venture participant are entitled to receive a quantity of hydrocarbons
equal to 50% of the total production, net of Bolivian taxes on production, with
YPFB receiving the remainder. Prior to 1993, one successful commercial gas
discovery well, the Los Suris No. 1, was drilled on Block XX and is shut in
pending the approval of a commercialization agreement by the Government of
Bolivia. A plan of development for Block XX has been approved by YPFB and the
Government of Bolivia. Under the plan of development, the Company drilled a
well, the Los Suris No. 2, which was completed in February 1994 and tested gross
production potential of approximately 9 MMcf of gas per day and approximately
120 barrels of condensate per day from two intervals. The Los Suris No. 2 is
also shut in pending the approval of the commercialization agreement. The plan
of development provides that, in order to postpone the relinquishment of
inactive acreage until July 15, 1995, the drilling of a second exploratory well
must be completed by September 30, 1994 and the drilling of a third exploratory
well must be commenced no later than the fourth quarter of 1994 and completed by
April 30, 1995. The Company may further postpone the relinquishment of inactive
acreage until July 15, 1996 by submitting, no later than July 1, 1995, an
additional two-well drilling program that is acceptable to YPFB. To guarantee
the drilling of the second and third exploratory wells, the Company has
submitted bank guarantees to YPFB in the aggregate amount of $4.0 million.
 
     In January 1994, three major energy companies announced a project to build
a $2 billion natural gas pipeline from Bolivia to Brazil. The Company
understands that the project is in the early planning stages, and that the
companies are seeking financing. There can be no assurance that these companies
will proceed with the project or, if so, whether or when the pipeline will
ultimately be completed. In any event, however, the Company does not believe
that the pipeline could be completed before 1997.

(1) The Company's natural gas production from Bolivia as presented above
     represents the Company's net production before Bolivian taxes.
 
(2) Average finding cost per Mcf represents costs incurred in oil and gas
     property acquisition, exploration and development activities for each
     indicated period divided by the changes in proved reserves resulting from
     extensions, discoveries and other additions and revisions of previous
     reserve quantity estimates during such period. See Note P of Notes to
     Consolidated Financial Statements.
 
(3) The present value of estimated future net revenues from proved crude oil and
     natural gas reserves at the end of each period presented has been
     calculated in accordance with the rules and regulations of the Commission.
     The calculation was made on a pre-tax basis, assuming no escalation in
     prices and using a 10% discount rate. This present value is not intended to
     be representative of the fair market value of the Company's proved
     reserves. The calculations of revenues and costs used to determine the
     present value of estimated future net revenues do not necessarily represent
     the amounts to be received or expended by the Company. For further
     information, see the discussion below and Note P of Notes to Consolidated
     Financial Statements.
 
(4) See "Investment Considerations," "Legal Proceedings -- Tennessee Gas
     Contract" and Notes K and P of Notes to Consolidated Financial Statements
     regarding litigation concerning the Tennessee Gas Contract.
 
     Proved developed reserves are proved reserves that are expected to be
recovered from existing wells with existing equipment and operating methods.
Proved undeveloped reserves are proved reserves that are expected to be
recovered from new wells drilled to known reservoirs on undrilled acreage for
which the existence and recoverability of such reserves can be estimated with
reasonable certainty, or from existing wells where a relatively major
expenditure is required to establish production.
 
     The present values shown should not be construed as the current market
value of the reserves. The 10% discount factor used to calculate present value,
which is specified by the Commission, is not necessarily the most appropriate
discount rate, and present value, no matter what discount rate is used, is
materially affected by assumptions as to timing of future production, which may
prove to be inaccurate. In addition, the
 
                                       44
<PAGE>   46
 
calculation of estimated future net revenues does not take into account the
effect of various cash outlays, including, among other things, general and
administrative costs and interest expense.
 
     Future prices received for production and future production costs may vary,
perhaps significantly, from the prices and costs assumed for purposes of these
estimates. There can be no assurance that the proved reserves will be developed
within the periods indicated or that prices and costs will remain constant.
There can be no assurance that actual production will equal the estimated
amounts used in the preparation of reserve projections. The reserve estimates
and present values of estimated future net revenues in the preceding table are
based on spot and contract prices in effect at the end of the indicated period,
without escalation. The prices used for the December 31, 1993 estimates were
$1.75 per Mcf for spot market gas in the Bob West Field, $7.73 per Mcf for gas
sold under the Tennessee Gas Contract and $1.13 per Mcf for Bolivian gas. Price
reductions decrease such present values by lowering the future net revenues
attributable to the reserves and will reduce the quantities of reserves that are
economically recoverable. Price increases have the opposite effect. Any
significant decline in prices of oil or gas, or an adverse outcome in the
Tennessee Gas litigation, could have a material adverse effect on the Company's
financial condition and results of operations.
 
     There are numerous uncertainties inherent in estimating quantities of
proved reserves and in projecting future rates of production and timing of
development expenditures. The data in the above tables represent estimates only.
Oil and gas reserve engineering must be recognized as a subjective process of
estimating underground accumulations of oil and gas that cannot be measured in
an exact way, and estimates of other engineers might differ materially from
those shown above. The accuracy of any reserve estimate is a function of the
quality of available data and engineering and geological interpretation and
judgment. Results of drilling, testing and production after the date of the
estimate may justify revisions. Accordingly, reserve estimates are often
materially different from the quantities of oil and gas that are ultimately
recovered.
 
     Netherland, Sewell & Associates, Inc., independent petroleum consultants,
prepared the foregoing estimates of the Company's proved reserves and the
present values of estimated future net revenues therefrom (except for estimates
of future income tax expense related thereto). No estimates of the Company's
reserves comparable to those included herein have been included in reports to
any federal agency other than the Commission.

OIL FIELD SUPPLY AND DISTRIBUTION
 
     The Company sells lubricants, fuels and specialty petroleum products
primarily to onshore and offshore drilling contractors. The Company's products
are sold through five land terminals and 13 marine terminals located in various
cities in Texas and Louisiana. These products are used to power and lubricate
machinery on drilling and production locations. The Company also provides
products for marine, commercial and industrial applications.
 
     Effective March 31, 1994, the Company discontinued its environmental
remediation products and services operations and recorded a charge of $.9
million in connection with such discontinuance.
 
GOVERNMENT REGULATION AND LEGISLATION
 
  United States
 
     Natural Gas Regulations. Historically, all domestic natural gas sold in
so-called "first sales" was subject to federal price regulations under the NGPA,
the Natural Gas Act (the "NGA"), and the regulations and orders issued by the
FERC in implementing such Acts. Under the Natural Gas Wellhead Decontrol Act of
1989, all remaining natural gas wellhead pricing, sales, certificate and
abandonment regulation of first sales by the FERC was terminated on January 1,
1993.
 
     The FERC also regulates interstate natural gas pipeline transportation
rates and service conditions, which affect the marketing of gas produced by the
Company, as well as the revenues received by the Company for sales of such
natural gas. Since the latter part of 1985, through its Order Nos. 436, 500 and
636, the FERC has endeavored to make natural gas transportation more accessible
to gas buyers and sellers on an open and nondiscriminatory basis, and the FERC's
efforts have significantly altered the marketing and pricing of natural gas. A
related effort has been made with respect to intrastate pipeline operations
pursuant to the FERC's authority under Section 311 of the NGPA, under which the
FERC establishes rules by which intrastate pipelines may participate in certain
interstate activities without becoming subject to full NGA jurisdiction. These
Orders have gone through various permutations, but have generally remained
intact as promulgated. The FERC considers these changes necessary to improve the
competitive structure of the interstate natural gas pipeline industry and to
create a regulatory framework that will put gas sellers into more direct
contractual relations with gas buyers than has historically been the case.
 
     The FERC's latest action in this area, Order No. 636, issued April 8, 1992,
reflected the FERC's finding that under the current regulatory structure,
interstate pipelines and other gas merchants, including producers, do not
compete on an equal basis. The FERC asserted that Order No. 636 was designed to
equalize that marketplace. This equalization process is being implemented
through negotiated settlements in individual pipeline service restructuring
proceedings, designed specifically to "unbundle" those services (e.g.,
gathering, transportation, sales and storage) provided by many interstate
pipelines so that producers of natural gas may secure services from the most
economical source, whether interstate pipelines or other parties. In many
instances, the result of the FERC initiatives has been to substantially reduce
or bring to an end the interstate pipelines' traditional role as wholesalers of
natural gas in favor of providing only gathering, transportation and storage
services for others which will buy and sell natural gas. The FERC has issued
final orders in all of the individual pipeline restructuring proceedings and all
of the interstate pipelines are now operating under new open access tariffs.
 
     Although Order No. 636 does not regulate gas producers, such as the
Company, the FERC has stated that Order No. 636 is intended to foster increased
competition within all phases of the natural gas industry. It is unclear what
impact, if any, increased competition within the natural gas industry under
Order No. 636 will have on the Company and its gas sales efforts. In addition,
numerous petitions seeking judicial review of Orders Nos. 636, 636A and 636B and
seeking review of the FERC's orders approving open access tariffs for the
individual pipelines have already been filed. Because the restructuring
requirements that emerge from this lengthy process may be significantly
different from those of Order No. 636 as originally promulgated, it is not
possible to predict what, if any, effect the final rule resulting from Order No.
636 will have on the Company.
 
                                       46
<PAGE>   48
 
The Company does not believe that it will be affected by any action taken with
respect to Order No. 636 any differently than other gas producers and marketers
with which it competes.
 
     In late 1993, the FERC initiated a proceeding seeking industry-wide
comments about its role in regulating natural gas gathering performed by
interstate pipelines or their affiliates. Numerous written and oral comments
have been received by the FERC concerning whether and how it should regulate
gathering activities, but the Company cannot predict what, if any, action the
FERC may take or whether such action will affect access to markets of its gas or
its own gas gathering facilities and activities.
 
     The oil and gas exploration and production operations of the Company are
subject to various types of regulation at the state and local levels. Such
regulation includes requiring drilling permits and the maintenance of bonds in
order to drill or operate wells; the regulation of the location of wells; the
method of drilling and casing of wells and the surface use and restoration of
properties upon which wells are drilled; and the plugging and abandoning of
wells. The operations of the Company are also subject to various conservation
regulations, including regulation of the size of drilling and spacing units or
proration units, the density of wells that may be drilled in a given area and
the unitization or pooling of oil and gas properties. In this regard, some
states allow the forced pooling or integration of lands and leases. In addition,
state conservation laws establish maximum rates of production from oil and gas
wells, generally prohibit the venting or flaring of gas and impose certain
requirements regarding the ratability of production. The effect of these
regulations is to limit the amounts of crude oil, condensate and natural gas the
Company can produce from its wells and the number of wells or the locations at
which the Company can drill.
 
     The North American Free Trade Agreement has further streamlined and
simplified procedures for the importation and exportation of gas among Mexico,
the United States and Canada. These changes could provide additional
opportunities to export gas to Mexico, but will more likely enhance the ability
of Canadian and Mexican producers to export natural gas to the United States,
thereby increasing competition in the domestic natural gas market.
 
     Additional proposals and proceedings that might affect the natural gas
industry are considered from time to time by Congress, the FERC, state
regulatory bodies and the courts. The Company cannot predict when or if any such
proposals might become effective, or their effect, if any, on the Company's
operations. The natural gas industry historically has been very heavily
regulated; therefore, there is no assurance that the less stringent regulatory
approach recently pursued by the FERC and Congress will continue indefinitely
into the future.
 
     Environmental Controls. Federal, state, area and local laws, regulations
and ordinances relating to the protection of the environment affect all
operations of the Company to some degree. One example of a federal environmental
law that would require operational additions and modifications is the Clean Air
Act, which was amended in 1990. While the Company believes that its facilities
generally are in substantial compliance with current regulatory standards for
air emissions, over the next several years the Company's facilities may be
required to comply with new requirements being adopted and to be promulgated by
the EPA and the states in which the Company operates. These regulations may
necessitate the installation of additional controls or other modifications or
changes in use for certain emission sources. At this time, the Company cannot
estimate when new standards will be imposed by the EPA or relevant state
agencies or what technologies or changes in processes the Company may have to
install or undertake to achieve compliance with any applicable new requirements.
 
     The passage of the federal Clean Air Act Amendments of 1990 prompted
adoption of regulations by the State obligating the Company to produce
oxygenated gasoline for delivery to the Anchorage and Fairbanks, Alaska markets
starting on November 1, 1992. Controversies surrounding the potential health
effects in arctic regions of oxygenated gasoline containing methyl tertiary
butyl ether ("MTBE") prompted the early discontinuance of the program in
Fairbanks in December 1992. On October 21, 1993, the United States Congress
granted Alaska one additional year of exemption from requiring the use of
oxygenated gasoline. However, state and local officials may still require the
use of these fuels at their option. In addition, the EPA has been directed to
conduct additional studies of potential health effects of oxygenated fuel in
Alaska. Additional federal regulations promulgated on August 21, 1990, and
scheduled to go into effect on October 1, 1993, set limits on the quantity of
sulphur in on-highway diesel fuels which the Company produces. The State
 
                                       47
<PAGE>   49
 
filed an application with the federal government in February 1993 for a waiver
from this requirement, since only 5% of the diesel fuel sold in Alaska is for
on-highway vehicles. The EPA supported the State's position and the formalities
for obtaining the exemption were completed on September 27, 1993. The EPA, in a
letter to the State dated September 30, 1993, indicated that the EPA was
completing the final documentation regarding the waiver and that Alaska would
have a low priority for enforcement of the diesel fuel regulations, pending the
publication of the final decision. The Company estimates that substantial
capital expenditures would be required to enable the Company to produce
low-sulphur diesel fuel to meet these federal regulations. If the State is
unable to obtain a waiver from the federal regulations, the Company would
discontinue the sales of diesel fuel for on-highway use. The Company estimates
that such sales accounted for approximately 1% of its refined product sales
during 1993. The Company is unable to predict the outcome of these matters;
however, the Company believes that the ultimate resolution of these matters will
not have a material impact on the Company's operations.
 
     Regulations promulgated by the EPA on September 23, 1988, require that all
underground storage tanks used for storing gasoline or diesel fuel either be
closed or upgraded not later than December 22, 1998, in accordance with
standards set forth in the regulations. The Company's service stations subject
to the upgrade requirements are limited to locations within Alaska, the majority
of which are located in nonresidential areas. Although the Company continues to
monitor, test and make physical improvements in its current operations, which
result in a cleaner environment, the Company was not required to make any
material capital expenditures for environmental control purposes during 1993.
The Company may be required to remove or upgrade underground storage tanks at
several of its current and former service station locations; however, the
Company does not expect to make any material capital expenditures for such
purposes. See "Legal Proceedings."
 
     The Company currently charters a vessel to transport crude oil from the
Valdez, Alaska pipeline terminal through Prince William Sound and Cook Inlet to
the Refinery. In addition, the Company routinely charters, on a term or spot
basis, additional tankers and barges for the shipment of crude oil and refined
products through Cook Inlet. The Federal Oil Pollution Act of 1990 requires, as
a condition of operation, that the Company submit an oil spill contingency plan
for the Refinery terminal facility located on Cook Inlet that demonstrates the
capability to respond to the "worst case discharge" to the maximum extent
practicable. Alaska law requires a contingency plan for that terminal providing
for containment or control, and cleanup, within 72 hours, of a spill equal to
the volume of the terminal's largest storage tank (50,000 Bbls). With respect to
the charter vessels employed by the Company to transport crude oil through
Prince William Sound and Cook Inlet to the Refinery, federal and Alaska law both
require contingency plans as a condition of navigation. The Company has obtained
State approval for its Cook Inlet Oil Discharge Contingency Plan and conditional
approval, which allows operations pending final State review, for a Tanker Spill
Prevention and Response Plan for Prince William Sound. To meet the federal and
State standards, the Company has entered into a contract with Alyeska Pipeline
Service Company ("Alyeska") to provide the initial spill response services in
Prince William Sound, with the Company to assume those responsibilities after
mutual agreement with Alyeska and the State and Federal On-Scene Spill Response
Coordinators. The Alaska legislature passed legislation in 1992, providing
limited immunity for spill response contractors, which has facilitated access to
contract extensions that will not be dependent on further legislative action.
The Company has also entered into an agreement with Cook Inlet Spill Prevention
& Response Inc. for oil spill response services in Cook Inlet. The Company
believes these contracts provide the additional services necessary to meet the
spill response requirements established by Alaska and federal law.
 
     For further information regarding environmental matters, see "Legal
Proceedings."
 
  Bolivia
 
     The Company's operations in Bolivia are subject to the Bolivian General Law
of Hydrocarbons and various other laws and regulations. The General Law of
Hydrocarbons imposes certain limitations on the Company's ability to conduct its
operations in Bolivia. In the Company's opinion, neither the General Law of
Hydrocarbons nor other limitations currently imposed by Bolivian laws,
regulations and practices will have a material adverse effect upon its Bolivian
operations.

TAXES
 
  United States
 
     The Revenue Reconciliation Act of 1993 imposed a 4.3 cents per gallon
"transportation fuels tax" effective October 1, 1993, and a tax on commercial
aviation fuel effective October 1, 1995. The Company does not believe such taxes
have had or will have a material adverse effect on the Company's operations.
 
  Bolivia
 
     The Company is subject to Bolivian taxation at the rate of 30% of the gross
production of hydrocarbons at the wellhead, which is retained and paid by YPFB
for the Company's account. In 1987, the Bolivian General Corporate Income Tax
Law was replaced by a tax system, including a value-added tax, which is not
imposed on net income. As a result, it is uncertain whether the Company can
treat the Bolivian hydrocarbons tax as creditable in the United States for
federal income tax purposes. However, due to the Company's net operating loss
carryforwards, the Company does not now, or in the near future, expect to use
these taxes as credits for federal income tax purposes.
 
     In 1990, the Bolivian Government passed a new General Law of Hydrocarbons
containing provisions designed to ensure the creditability, for United States
federal income tax purposes, of these hydrocarbon taxes if the Company makes an
election that may subject it to a higher Bolivian tax rate in the future.
Regulations under this new law have not been issued; however, the Company does
not anticipate that this new law will have a material adverse effect on the
Company's Bolivian operations.

                     POSSIBLE CHANGE IN BOARD OF DIRECTORS
 
     Under the terms of the Amended MetLife Memorandum, MetLife Louisiana has
agreed to request that Messrs. Ray C. Adam, Charles F. Luce, Stewart G. Nagler
and William S. Sneath resign in the event the MetLife Louisiana Option is
exercised in full. The Company believes that if the MetLife Louisiana Option is
exercised in full, those directors will resign. The Nominating Committee of the
Board of Directors and the Board of Directors have not determined whether the
vacancies that would be created by such resignations will be filled or, if so,
who would be nominated. The members of the Board of Directors have reached an
understanding that, if the MetLife Louisiana Option has not been exercised in
full by June 30, 1994, on such date the Board of Directors will appoint one
additional director to be selected from a list, to be proposed by MetLife
Louisiana and Oakville N.V. (another major stockholder of the Company), of
persons associated with or recommended by major stockholders.
 
                               LEGAL PROCEEDINGS
 
     Tennessee Gas Contract. The Company is selling a portion of the gas from
its Bob West Field to Tennessee Gas under a Gas Purchase and Sales Agreement
which provides that the price of gas shall be the maximum price as calculated in
accordance with Section 102(b)(2) of the NGPA (the "Contract Price").
 
     Tennessee Gas filed suit against the Company alleging that the gas contract
is not applicable to the Company's properties and that the gas sales price
should be the price calculated under the provisions of Section 101 of the NGPA
rather than the Contract Price. During March 1994, the Contract Price was $7.84
per Mcf, the Section 101 price was $4.58 per Mcf and the average spot market
price was $2.09 per Mcf. Tennessee Gas also claimed that the contract should be
considered an "output contract" under Section 2.306 of the Texas Business and
Commerce Code and that the increases in volumes tendered under the contract
exceeded those allowable for an output contract. The Company continues to
receive payment from Tennessee Gas based on the Contract Price for all volumes
that are subject to the contract under the Company's interpretation.
 
     The District Court trial judge returned a verdict in favor of the Company
on all issues. On appeal by Tennessee Gas, the Court of Appeals affirmed the
validity of the Tennessee Gas Contract as to the Company's properties and held
that the price payable by Tennessee Gas for the gas was the Contract Price. The
Court of Appeals remanded the case to the trial court based on its determination
(i) that the Tennessee Gas Contract was an output contract and (ii) that a fact
issue existed as to whether the increases in the volumes of gas tendered to
Tennessee Gas under the contract were made in bad faith or were unreasonably
disproportionate to prior tenders. The Company is seeking review of the
appellate court ruling on the output contract issue in the Supreme Court of
Texas. Tennessee Gas is seeking review of the appellate court ruling denying the
remaining Tennessee Gas claims in the Supreme Court of Texas.
 
     Although the outcome of any litigation is uncertain, management, based upon
advice from outside legal counsel, is confident that the decision of the trial
and appellate courts will ultimately be upheld as to the validity of the
Tennessee Gas Contract and the Contract Price. Therefore, if the Supreme Court
of Texas does
 
                                       52
<PAGE>   54
 
not grant the Company's petition for writ of error and affirms the appellate
court ruling, the Company believes that the only issue for trial should be
whether the increases in the volumes of gas tendered to Tennessee Gas from the
Company's properties were made in bad faith or were unreasonably
disproportionate. The appellate court decision was the first reported decision
in Texas holding that a take-or-pay contract was an output contract. As a
result, it is not clear what standard the trial court would be required to apply
in determining whether the increases were in bad faith or unreasonably
disproportionate. The appellate court acknowledged in its opinion that the
standards used in evaluating other kinds of output contracts would not be
appropriate in this context. The Company believes that the appropriate standard
would be whether the development of the field was undertaken in a manner that a
prudent operator would have undertaken in the absence of an above-market sales
price. Under that standard, the Company believes that, if this issue is tried,
the development of its gas properties and the resulting increases in volumes
tendered to Tennessee Gas will be found to have been reasonable and in good
faith. Accordingly, the Company has recognized revenues, net of production taxes
and marketing charges, for natural gas sales through March 31, 1994, under the
Tennessee Gas Contract based on the Contract Price, which net revenues
aggregated $21.1 million more than the Section 101 prices and $38.9 million in
excess of the spot market prices. If Tennessee Gas ultimately prevails in this
litigation, the Company could be required to return to Tennessee Gas the
difference between the spot market price for gas and the Contract Price, plus
interest, if awarded by the court. In addition, the present value of estimated
future net revenues on a pre-tax basis from the Company's proved domestic
reserves has been calculated based in part on the price being paid by Tennessee
Gas at the date of determination. At March 31, 1994, such present value was
$171.0 million. If calculated using March 31, 1994 spot market prices instead of
the Contract Price, such present value would have been $92.0 million.
 
   
     On June 7, 1994, Tennessee Gas filed a motion with the court requesting
that the court permit Tennessee Gas to pay the difference between the Contract
Price and the spot market price into the registry of the court on a monthly
basis in lieu of paying the Company the Contract Price or, in the alternative,
that the court require the Company to post a bond to secure any amount which the
Company might owe Tennessee Gas if Tennessee Gas were to ultimately prevail in
the litigation. The Company believes that Tennessee Gas is not entitled to avoid
paying the Contract Price by such monthly payments but that Tennessee Gas may be
able to cease making payments above spot market prices pending the ultimate
outcome of the litigation if it posts a bond. The Company does not believe that
the court will require the Company to post a bond. If the court were to permit
Tennessee Gas to reduce its payments to the Company to spot market prices
pending resolution of the litigation, the Company's cash flow would be
substantially reduced. The Company believes that at present spot market prices
the Company would be able to fund its capital expenditure program and comply
with its financial covenants under the Revolving Credit Facility if the court
were to grant the request of Tennessee Gas.
    
 
   
     An adverse judgment in this case could have a material adverse effect on
the Company. See Notes K and P of Notes to Consolidated Financial Statements.
    
 
   
     Refund Claim. In May 1994, a former customer threatened to file suit
against the Company for a refund in the amount of approximately $1.2 million,
plus interest of approximately $4.4 million and attorney's fees, related to two
gasoline purchases from the Company in 1979. The customer also alleges
entitlement to treble damages and punitive damages in the aggregate amount of
$16.8 million. The refund claim is based on allegations that the Company
renegotiated the acquisition price of gasoline sold to the customer and failed
to pass on the benefit of the renegotiated price to the customer in violation of
Department of Energy price and allocation controls then in effect. The Company
believes the claim is without merit and anticipates that the ultimate resolution
of this matter will not have a material adverse effect on the Company.
    
 
     ADEC Consent Order. In March 1991, the Company entered into a Consent Order
with the Alaska Department of Environmental Conservation ("ADEC") substantially
similar to Consent Orders reached with the EPA in September 1989. These Consent
Orders provide for the investigation and cleanup of hydrocarbons in the soil and
groundwater at the Refinery, which resulted from sewer hub seepage associated
with the underground oil/water sewer system. The Consent Orders formalized
efforts, which commenced in 1987, to remedy the presence of hydrocarbons in the
soil and groundwater and provide for the performance of additional future work.
The Company has replaced or rebuilt the drainage hubs and has initiated a
subsurface
 
                                       53
<PAGE>   55
 
monitoring and interception system designed to identify the extent of
hydrocarbons present in the groundwater and to remove the hydrocarbons. The
Company estimates that annual expenditures of approximately $1.5 million will be
required in the future to operate such subsurface monitoring and interception
systems. The majority of such expenses will be covered by insurance through
1995.
 
     Clean Air Act Matters. In March 1992, the Company received a notice from
the EPA alleging possible violations by the Company of the New Source
Performance Standards under the Clean Air Act at the Refinery. The EPA has the
statutory authority to assess civil penalties for the alleged violations of up
to $25,000 per day for each violation, but the EPA has not to date assessed a
penalty against the Company for its alleged violations. Although the Company is
continuing in its efforts to resolve these issues with the EPA, no final
resolution has been reached. The Company believes that the ultimate resolution
of this matter will not have a material adverse effect upon the Company's
business or financial condition.
 
     Mud and Gulf Coast Superfund Sites. The Company, along with over 100 other
parties, has been identified by the EPA as a PRP pursuant to CERCLA for the Mud
and Gulf Coast Superfund sites in Abbeville, Louisiana. The Company arranged for
the disposal of a minimal amount of materials at these locations, but CERCLA
imposes joint and several liability on each PRP. The EPA is seeking
reimbursement for its response costs incurred to date at each site, as well as a
commitment from the PRPs either to conduct future remedial activities or to
finance such activities.
 
     The Company has entered into a de minimis settlement with the EPA at the
Gulf Coast site for $2,500. At this time, the Company is unable to determine the
extent of the Company's liability related to the Mud site; however, based on the
Gulf Coast settlement, the Company believes that the aggregate amount of such
liability, if any, would not have a material adverse effect on the Company.
 
   
     Recapitalization Matters. In October 1993, Croyden Associates, a holder of
shares of the Company's $2.16 Preferred Stock, filed a class action suit in
Delaware Chancery Court on behalf of itself and all other holders of the $2.16
Preferred Stock. The suit alleged that the Company and its directors breached
their fiduciary duties to the holders of the $2.16 Preferred Stock in
formulating the originally proposed terms of the Recapitalization, which
provided for the reclassification of each share of $2.16 Preferred Stock into
3.5 shares of Common Stock or, at the holder's option, 2.75 shares of Common
Stock and .25 share of a new issue of preferred stock. The suit sought, among
other things, monetary damages and to enjoin the Recapitalization. On April 13,
1994, the court entered an order that approved a settlement agreement which
provided for (i) the exchange of each share of $2.16 Preferred Stock into 4.9
shares of Common Stock and (ii) the issuance of up to 131,956 shares of Common
Stock and the payment of $500,000 by the Company for plaintiff's attorneys' fees
and expenses awarded by the Delaware Chancery Court. By order dated April 20,
1994, the court awarded plaintiff's counsel $500,000 and 73,913 shares of Common
Stock out of the 131,956 shares of Common Stock applied for by such counsel for
legal fees and expenses, with the remaining shares to be issued to the former
holders of $2.16 Preferred Stock as of the close of business on February 9,
1994. Subsequently, counsel retained by a party objecting to the settlement was
awarded legal fees and expenses totalling approximately $11,500 to be paid in
the form of 1,127 shares of Common Stock out of the 58,043 shares of Common
Stock to be issued to the former holders of $2.16 Preferred Stock. The shares
awarded to counsel for the holders of $2.16 Preferred Stock have been issued;
the shares to be issued to the former holders of $2.16 Preferred Stock and to
counsel for the objecting party will be issued upon the court's orders becoming
final and nonappealable.

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
   
     The authorized capital stock of the Company consists of 50,000,000 shares
of Common Stock and 5,000,000 shares of preferred stock, no par value, of which
2,875,000 shares have been designated as $2.20 Preferred Stock and 250,000
shares have been designated as Series A Participating Preferred Stock. At June
21, 1994, there were outstanding 22,531,093 shares of Common Stock and 2,875,000
shares of $2.20 Preferred Stock. Each share of $2.20 Preferred Stock has a
liquidation value of $20 (plus accrued and unpaid dividends). Chemical Bank,
N.A. is the transfer agent and registrar for the Common Stock and the $2.20
Preferred Stock.
    
 
     Each outstanding share of the Company's capital stock is fully paid and
nonassessable.
 
     The following descriptions summarize the material terms and provisions of
the Company's capital stock, but do not purport to be complete, and are
qualified in their entirety by reference to the Company's Certificate of
Incorporation, as amended, and the Amended MetLife Memorandum, which are filed
as exhibits to the Registration Statement of which this Prospectus is a part.
 
COMMON STOCK
 
  Dividends
 
     Holders of Common Stock are entitled to dividends, when and if declared by
the Board of Directors, but only out of funds legally available therefor,
subject to (i) the rights of the holders of shares ranking prior to Common Stock
as to dividends and distributions, including the $2.20 Preferred Stock, and (ii)
limitations on the payment of dividends on Common Stock contained in certain of
the Company's outstanding debt instruments. Holders of preferred stock,
including the $2.20 Preferred Stock, are entitled to the payment of dividends
for the current and all prior quarterly periods before any dividend may be
declared upon Common Stock or before any other payment on account of, or the
setting aside of money for, the purchase, redemption or other retirement of
Common Stock may be made. The Company is presently effectively prohibited from
paying cash dividends on its Common Stock. See "Price Range of Common Stock and
Dividend Policy" and Note I of Notes to Consolidated Financial Statements.
 
  Liquidation Rights
 
     Upon the liquidation, dissolution or winding up of the affairs of the
Company, whether voluntary or involuntary, each share of each class of preferred
stock, including the $2.20 Preferred Stock, is entitled, before any distribution
is made to holders of Common Stock, to receive the amount of the liquidation
value of such class of preferred stock, together with all accrued and unpaid
dividends to the date fixed for distribution. After the stated amounts payable
upon liquidation on the preferred stock have been paid in full or provision for
the payment has been made, the remaining net assets of the Company will be
distributed pro rata to the holders of Common Stock.
 
  Voting Rights
 
     Each share of Common Stock is entitled to one vote for all purposes, except
as otherwise provided by law or as expressly provided in the Certificate of
Incorporation.
 
$2.20 PREFERRED STOCK
 
     Pursuant to the Amended MetLife Memorandum, MetLife Louisiana, the sole
holder of the $2.20 Preferred Stock, contractually agreed to substantial
modifications in the terms of the $2.20 Preferred Stock. MetLife Louisiana also
agreed not to sell any shares of the $2.20 Preferred Stock unless the buyer
agrees that such shares will remain subject to MetLife Louisiana's agreements
and waivers relating to the $2.20 Preferred Stock. The following description
incorporates the effect of such contractual modifications.
 
                                       55
<PAGE>   57
 
  Dividends
 
     Holders of $2.20 Preferred Stock are entitled to receive, when and as
declared by the Board of Directors, but only out of funds legally available
therefor, cumulative cash dividends presently payable at, but not exceeding, the
rate of $2.20 per share per annum. Dividends are payable quarterly, in cash, on
February 15, May 15, August 15 and November 15, and are cumulative. The Company
is prohibited from declaring and paying dividends on any junior stock and from
redeeming, repurchasing or making a sinking fund payment on any junior stock or
stock on a parity with the $2.20 Preferred Stock in the payment of dividends
unless all prior dividends accumulated on the $2.20 Preferred Stock, including
the current quarterly period, have been paid or declared and set aside for
payment. See " -- Ranking."
 
     Pursuant to the Amended MetLife Memorandum, MetLife Louisiana has agreed to
consider all accrued and unpaid dividends on the $2.20 Preferred Stock as of
February 9, 1994, to have been paid and to allow the Company to pay future
dividends on the $2.20 Preferred Stock in Common Stock in lieu of cash, provided
that the Company continues to pay all quarterly dividends either in Common Stock
or in cash. For purposes of determining the number of shares of Common Stock to
be issued in payment in lieu of a cash dividend, the Common Stock will be valued
at the average closing price for the Common Stock on the New York Stock Exchange
for the ten trading days commencing on the first trading day after the Company
publicly announces its intention to use Common Stock in lieu of cash to pay the
dividend.
 
  Liquidation Rights
 
     The $2.20 Preferred Stock has a liquidation preference of $20 per share,
plus accrued and unpaid dividends, before any distribution of assets is made to
holders of Common Stock or any other junior stock. If assets available for
distribution are insufficient to pay the full liquidation preference, all
classes of capital stock, if any, ranking on a parity as to liquidation rights
with the $2.20 Preferred Stock are entitled to share ratably in any such
distribution.
 
  Redemption
 
     The $2.20 Preferred Stock is redeemable, but only out of funds legally
available therefor, at the option of the Company, in whole or in part, on not
more than 45 and not less than 30 days' notice, at $20 per share plus dividends
accrued to the redemption date. If not sooner redeemed, on each February 15,
beginning on February 15, 1994, the Company is required to set aside funds and
effect the redemption of 6 2/3% (subject to certain credits) of the number of
shares of $2.20 Preferred Stock outstanding on February 15, 1994. If the Company
fails to pay dividends on the $2.20 Preferred Stock in an amount equal to at
least 12 quarterly dividends (whether or not consecutive) or if the Company
fails to make redemptions of $2.20 Preferred Stock when required with respect to
at least the number of shares to be redeemed in any three-year period, and if
all of the outstanding shares of $2.20 Preferred Stock are held by MetLife
Louisiana or by its affiliates, the Company is required to redeem, out of funds
legally available therefor, at the option of MetLife Louisiana or its affiliates
(the "$2.20 Preferred Stock Put Option"), within 60 days of the occurrence
thereof, all of the outstanding shares of $2.20 Preferred Stock at the
applicable redemption price plus dividends accrued to the redemption date. Prior
to any such redemption, the Company shall pay or make provision for payment of
all accrued and unpaid dividends on all shares of the Company's preferred stock.
 
     Pursuant to the Amended MetLife Memorandum, MetLife Louisiana has agreed to
waive the $2.20 Preferred Stock Put Option and the annual mandatory redemption
requirements associated with the $2.20 Preferred Stock. The Company has agreed
not to exercise its right to optionally redeem the $2.20 Preferred Stock at any
time prior to February 9, 1998.
 
  Ranking
 
     The $2.20 Preferred Stock ranks senior to the Common Stock as to
liquidation and dividends.

  Conversion
 
     The shares of $2.20 Preferred Stock are convertible, at the option of the
holder thereof, into shares of Common Stock at a rate of 0.8696 shares of Common
Stock for each share of $2.20 Preferred Stock. The conversion price is subject
to adjustment in certain events, including (i) dividends (and other
distributions) payable to all holders of Common Stock in shares of the Company's
capital stock, including Common Stock, (ii) the issuance to all holders of
Common Stock of rights or warrants which entitle them to subscribe for or
purchase Common Stock at a price per share less than the current market price
(as defined), (iii) subdivisions, combinations and reclassifications of Common
Stock and (iv) distributions to all holders of Common Stock of evidences of
indebtedness of the Company or assets (including securities, but excluding those
rights or warrants referred to above and dividends and distributions paid in
cash out of current or retained earnings). In case of certain consolidations or
mergers to which the Company is a party or the sale or transfer of all or
substantially all of the assets of the Company, each share of $2.20 Preferred
Stock then outstanding is entitled to be converted after such consolidation,
merger, sale or transfer into the kind and amount of securities, cash and other
property receivable upon the consolidation, merger, sale or transfer by a holder
of a number of shares of Common Stock into which such share of $2.20 Preferred
Stock might have been converted immediately prior to such consolidation, merger,
sale or transfer. Fractional shares of Common Stock are not to be issued upon
conversion, but, in lieu thereof, the Company will pay a cash adjustment based
on market price.
 
     Pursuant to the Amended MetLife Memorandum, MetLife Louisiana has agreed to
refrain from exercising the conversion rights of the $2.20 Preferred Stock.
 
  Voting Rights
 
     The holders of $2.20 Preferred Stock are entitled to one vote per share,
voting together as a single class with the holders of Common Stock and any other
class or series which may similarly be entitled to vote with the holders of
Common Stock, on all matters on which the shares of Common Stock may vote,
including the elections of directors.
 
     The affirmative vote of the holders of two-thirds of the outstanding shares
of $2.20 Preferred Stock, voting as a separate class, is required (i) to
authorize or increase the authorized amount of, or authorize any obligation or
security convertible into or evidencing the right to purchase shares of, any
additional class or series of stock ranking prior to the $2.20 Preferred Stock
as to the payment of dividends or the distribution of assets, (ii) to amend,
alter or repeal the voting powers, preferences or rights of the $2.20 Preferred
Stock in any respect adverse to the holders thereof or (iii) to authorize the
merger or consolidation of the Company if such merger or consolidation would
have an effect on the $2.20 Preferred Stock substantially similar to (i) or (ii)
above.
 
     In addition, the affirmative vote of the holders of a majority of the
outstanding shares of $2.20 Preferred Stock, voting together as a single class,
is required in order to authorize any increase in authorized $2.20 Preferred
Stock or authorize or increase the authorized amount of, or authorize any
obligation or security convertible into or evidencing the right to purchase
shares of, any additional class or series of stock ranking on parity with the
$2.20 Preferred Stock as to the payment of dividends or the distribution of
assets.
 
     Pursuant to the Amended MetLife Memorandum, the Board of Directors was
expanded from 13 to 16 members, and three new directors were selected from a
list proposed by MetLife Louisiana to fill the vacancies created thereby. The
three persons proposed by MetLife Louisiana were elected to the Board of
Directors. In addition, the Company amended its By-Laws to allow for the calling
of a special meeting of stockholders to elect one additional director in the
event a majority of the 16-member Board of Directors cannot be obtained on a
consistent basis. One of the three new directors proposed by MetLife Louisiana
has resigned and a second chose not to stand for re-election at the Company's
1994 annual meeting (which was held on May 26, 1994). The members of the Board
of Directors have reached an understanding that, if the MetLife Louisiana Option
has not been exercised in full by June 30, 1994, on such date the Board of
Directors will appoint one additional director to be selected from a list, to be
proposed by MetLife Louisiana and Oakville N.V., of persons associated with or
recommended by major stockholders.

  Failure to Redeem $2.20 Preferred Stock or Pay Dividends
 
     If the Company fails to make redemptions of $2.20 Preferred Stock when
required with respect to at least the number of shares to be redeemed on any two
redemption dates, and if the default in dividends described in the next
paragraph is not then in effect ("Dividend Default"), the number of directors
then constituting the Board of Directors shall be increased by two and the
holders of the $2.20 Preferred Stock, voting separately as a single class, shall
have the right to elect the two additional members of the Board of Directors.
Such right will expire when the arrearage in such redemptions has been cured or
when a Dividend Default has occurred.
 
     If the Company fails to pay dividends on the $2.20 Preferred Stock in an
amount equal to at least six quarterly dividends (whether or not consecutive),
the number of directors then constituting the Board of Directors shall be
increased by two and the holders of the $2.20 Preferred Stock, voting together
as a single class with the holders of any other series of preferred stock having
similar voting rights, shall have the right to elect the two additional members
of the Board of Directors. Such right will expire when all accrued but unpaid
dividends on the preferred stock have been paid and dividends on the preferred
stock for the then current quarterly period have been paid or declared and set
apart.
 
  Future Preferred Stock and Offer to Repurchase
 
     Pursuant to the Amended MetLife Memorandum, the Company has agreed to issue
to MetLife Louisiana, upon MetLife Louisiana's request, a new series of
preferred stock ("Future Preferred Stock") in the event that the MetLife
Louisiana Option is not exercised in full prior to its expiration and has agreed
to offer to repurchase 287,500 shares of the $2.20 Preferred Stock or, if issued
in lieu thereof, the Future Preferred Stock, each year commencing June 30, 1998.
 
RIGHTS AGREEMENT AND PARTICIPATING PREFERRED STOCK
 
     Effective December 16, 1985, the Board of Directors declared a distribution
of one preferred stock purchase right on each outstanding share of Common Stock.
Each right entitles stockholders until December 16, 1995 (or such later date as
the Company may provide) to purchase one one-hundredth of a share of
Participating Preferred Stock, no par value ("Participating Preferred Stock"),
at an initial exercise price of $35 for each one one-hundredth of a share.
Certificates delivered upon transfer or new issuance of Common Stock contain a
notation incorporating by reference the agreement pursuant to which such rights
have been issued.
 
     The rights are not exercisable, or transferable apart from the Common
Stock, until ten days after any person (an "Acquiring Person") acquires shares
of the Company's capital stock having at least 20% of the general voting power
without approval of the Board of Directors. Separate certificates representing
the rights will be mailed to holders of Common Stock as of such date.
 
     If, after an Acquiring Person acquires shares of the Company's capital
stock having 20% of the general voting power in a transaction not approved by
the Board of Directors, the Company were to be acquired in a merger or other
business combination transaction, each right would require that provision be
made for its holder to be allowed to purchase, at the then-current exercise
price of the right, that number of shares of common stock of the surviving
company which at the time of such transaction would have a market value of two
times the exercise price of the right. Thus, for example, if the market value of
the acquiring company's common stock at the time of the transaction were $17.50
per share and the exercise price of the rights were $35 per right, each right
would entitle a holder to receive upon exercise four shares of the acquiring
company's common stock.
 
     If the Company were the surviving corporation in the merger and the Common
Stock was not changed, provision would be made so that each holder of a right
(other than the Acquiring Person) would receive upon its exercise that number of
shares of Participating Preferred Stock having a market value of two times the
exercise price of the right.
 
     In order to allow for flexibility, the rights are subject to redemption at
the election of the Board of Directors at $.05 per right at any time prior to
ten days after someone becomes an Acquiring Person. Once any
 
                                       58
<PAGE>   60
 
party becomes an Acquiring Person and such ten-day period has elapsed, the
rights become nonredeemable. The rights have no voting or dividend rights.
 
     The Participating Preferred Stock is nonredeemable and ranks on a parity
with other series of Preferred Stock. Each share has a minimum preferential
quarterly dividend rate of $1.00 per share, but is entitled to an aggregate
dividend of 100 times any dividend declared on the Common Stock (other than a
dividend payable in shares of Common Stock).
 
     In the event of liquidation, the holders of the Participating Preferred
Stock will be entitled to receive a preferred liquidation payment of $35 per
share, but will be entitled to receive an aggregate liquidation payment equal to
such $35 per share plus 100 times any payment made per share of Common Stock.
Each share of Participating Preferred Stock will be entitled to 100 votes,
voting together with the Common Stock and any other class of the Company's
capital stock having general voting power. Finally, in the event of any merger,
consolidation or other transaction in which shares of Common Stock are exchanged
for or changed into other stock or securities, cash or other property, the
Participating Preferred Stock requires that provision be made so that each share
of Participating Preferred Stock will receive 100 times the amount received per
share of Common Stock. The foregoing rights of the Participating Preferred Stock
are protected against dilution in certain events. Fractional shares of
Participating Preferred Stock in integral multiples of one one-hundredth of a
share will be issuable. Because of the nature of the Participating Preferred
Stock dividend, liquidation and voting rights, the value of a one one-hundredth
interest in a share of Participating Preferred Stock purchasable with each right
should generally approximate the value of one share of Common Stock.
 
     Pursuant to the Amended MetLife Memorandum, the Company has agreed to cause
the preferred stock purchase rights to cease to exist in the event the Company
has not fully exercised the MetLife Louisiana Option before its expiration.

     The Underwriting Agreement provides that the obligations of the
Underwriters are subject to certain conditions precedent and that the
Underwriters will be obligated to purchase all of the Shares offered hereby
(other than those Shares covered by the over-allotment option described below)
if any are purchased. The Underwriting Agreement provides that, in the event of
a default by an Underwriter, in certain circumstances, the purchase commitments
of non-defaulting Underwriters may be increased or the Underwriting Agreement
may be terminated.
 
     The Company has granted to the Underwriters an option, expiring at the
close of business on the 30th day after the date of the initial public offering
of the Common Stock offered hereby, to purchase up to 500,000 additional shares
of Common Stock at the initial public offering price less the underwriting
discount, all as set forth on the cover page of this Prospectus. The
Underwriters may exercise such option only to cover over-allotments in the sale
of the shares of Common Stock. To the extent such option is exercised, each
Underwriter will become obligated, subject to certain conditions, to purchase
approximately the same percentage of such additional shares of Common Stock as
it was obligated to purchase pursuant to the Underwriting Agreement.
 
   
     The Company has been advised by the Representatives that the Underwriters
propose to offer the Shares to the public initially at the public offering price
set forth on the cover page of this Prospectus and, through the Representatives,
to certain dealers at such price less a concession of $0.32 per Share; that the
Underwriters and such dealers may allow a discount of $0.05 per Share on sales
to certain other dealers; and that after the initial public offering the public
offering price and concession and discount to dealers may be changed by the
Representatives.
    
 
     The Company, MetLife Louisiana, Oakville N.V. and each of the Company's
directors and executive officers, have agreed not to offer, sell, contract to
sell or otherwise dispose of any shares of Common Stock or
 
                                       60

the Company's preferred stock (other than, in the case of MetLife Louisiana, to
the Company, pursuant to the MetLife Louisiana Option) or any other securities
convertible into or exchangeable for Common Stock or the Company's preferred
stock other than upon conversion of convertible securities outstanding on the
date hereof or pursuant to employee benefit plans (including, but not limited
to, stock option plans) for a period of 90 days after the date of this
Prospectus in the case of the Company and each of the Company's directors and
executive officers, for a period of 60 days after the date of this Prospectus in
the case of Oakville N.V. (subject to earlier termination upon the occurrence of
certain events), and through July 22, 1994 (subject to earlier termination upon
the occurrence of certain events) in the case of MetLife Louisiana, in each case
without the prior written consent of CS First Boston Corporation.
 
     The Company has agreed to indemnify the Underwriters against certain
liabilities, including civil liabilities under the Securities Act of 1933, as
amended (the "Act"), or contribute to payments which the Underwriters may be
required to make in respect thereof.
 
   
     During the past 12 months, Smith Barney Inc. and Jefferies & Company, Inc.
have provided investment banking and advisory services to the Company, for which
they have received customary compensation.

RESALE RESTRICTIONS
 
   
     The distribution of the Shares in Canada is being made only on a private
placement basis exempt from the requirement that the Company prepare and file a
prospectus with the securities regulatory authorities in each province where
trades of Shares are effected. Accordingly, any resale of the Shares in Canada
must be made in accordance with applicable securities laws which will vary
depending on the relevant jurisdiction, and which may require resales to be made
in accordance with available statutory exemptions or pursuant to a discretionary
exemption granted by the applicable Canadian securities regulatory authority.
Purchasers are advised to seek legal advice prior to any resale of the Shares.
    
 
   
REPRESENTATIONS OF PURCHASERS
    
 
   
     Each purchaser of Shares in Canada who receives a purchase confirmation
will be deemed to represent to the Company and the dealer from whom such
purchase confirmation is received that (i) such purchaser is entitled under
applicable provincial securities laws to purchase such Shares without the
benefit of a prospectus qualified under such securities laws, (ii) where
required by law, that such purchaser is purchasing as principal and not as
agent, and (iii) such purchaser has reviewed the text above under "Resale
Restrictions."
    
 
   
RIGHTS OF ACTION AND ENFORCEMENT
    
 
   
     The securities being offered are those of a foreign issuer and Ontario
purchasers will not receive the contractual right of action prescribed by
section 32 of the Regulation under the Securities Act (Ontario). As a result,
Ontario purchasers must rely on other remedies that may be available, including
common law rights of action for damages or rescission or rights of action under
the civil liability provisions of the U.S. federal securities laws.
    
 
   
     All of the issuer's directors and officers as well as the experts named
herein may be located outside of Canada and, as a result, it may not be possible
for Ontario purchasers to effect service of process within Canada upon the
issuer or such persons. All or a substantial portion of the assets of the issuer
and such persons may be located outside of Canada and, as a result, it may not
be possible to satisfy a judgment against the issuer or such persons in Canada
or to enforce a judgment obtained in Canadian courts against such issuer or
persons outside of Canada.

                PRO FORMA CONDENSED CONSOLIDATED FINANCIAL DATA
 
   
     The unaudited pro forma financial data set forth the Company's historical
financial data adjusted to give effect to the Recapitalization and the Offering,
assuming net proceeds of $52.3 million, after deduction of $3.2 million of
underwriting discounts and estimated expenses, from the issuance of 5,350,000
shares of the Company's Common Stock at an offering price of $10.375 per share
pursuant to the Offering. The pro forma financial data assume that the proceeds
from the Offering are used to exercise the MetLife Louisiana Option to the
extent of such proceeds and take into account the payment of a cash dividend on
the $2.20 Preferred Stock in May 1994 from the Company's available cash. See
"Use of Proceeds."
    
 
     The pro forma financial data have been prepared assuming the

            NOTES TO PRO FORMA CONDENSED CONSOLIDATED FINANCIAL DATA
 
(a)  The Company is currently prohibited under the terms of the indenture
     governing the Subordinated Debentures from repurchasing its capital stock,
     including the shares of $2.20 Preferred Stock and Common Stock subject to
     the MetLife Louisiana Option, except from the proceeds of a substantially
     concurrent sale of other shares of capital stock. If the net proceeds to
     the Company from the Offering are not sufficient to exercise the MetLife
     Louisiana Option in full, the Company would be able to exercise the MetLife
     Louisiana Option only to the extent of the net proceeds from the Offering.
 
(b)  The Company is involved in litigation with Tennessee Gas relating to a
     natural gas sales contract. For additional information concerning this
     dispute, see "Investment Considerations," "Legal Proceedings -- Tennessee
     Gas Contract" and Notes K and P of Notes to Consolidated Financial
     Statements.
 
(c)  Interest expense in 1993 is net of a $5.2 million credit for settlement of
     several state tax issues (see Note H of Notes to Consolidated Financial
     Statements). Excluding this credit, interest expense for 1993 would have
     been $19.7 million.
 
(d)  No tax effect has been reflected in the adjustments to the Pro Forma
     Statements of Condensed Consolidated Operations, as the Company has
     provided a 100% valuation allowance to the extent of its net deferred tax
     assets.
 
(e)  In February 1994, the Company consummated exchange offers and adopted
     amendments to its Restated Certificate of Incorporation pursuant to which
     the Company's outstanding debt and preferred stock were restructured. A
     description of the significant components of this Recapitalization,
     together with the applicable accounting effects, follows:
 
     Subordinated Debentures in the principal amount of $44.1 million were
     tendered in exchange for a like principal amount of new Exchange Notes,
     which satisfied the 1994 sinking fund requirement and, except for $.9
     million, will satisfy sinking fund requirements for the Subordinated
     Debentures through 1997. The Exchange Notes bear interest at 13% per annum,
     are scheduled to mature on December 1, 2000 and have no sinking fund
     requirements. The exchange resulted in an extraordinary loss of $4.8
     million representing the excess of the market value of the Exchange Notes
     over the carrying value of the Subordinated Debentures, increased by the
     applicable unamortized debt issuance costs. Interest and other expense is
     assumed to decrease by $.1 million for the Subordinated Debentures retired
     and increased by $.1 million for the Exchange Notes issued.
 
   
     The 1,319,563 outstanding shares of $2.16 Preferred Stock of the Company,
     together with accrued and unpaid dividends of $9.5 million at February 9,
     1994, were reclassified into 6,465,859 shares of Common Stock of the
     Company. The Company also agreed to issue 131,956 shares of Common Stock on
     behalf of the holders of $2.16 Preferred Stock and to pay $500,000 for
     certain of their legal fees and expenses in connection with the settlement
     of litigation related to the reclassification. The court awarded $500,000
     and 73,913 shares of Common Stock for such legal fees and expenses, 1,127
     shares to counsel retained by a party objecting to the settlement, with the
     remaining 56,916 shares to be issued to the former holders of $2.16
     Preferred Stock. The shares awarded to counsel for the holders of $2.16
     Preferred Stock have been issued; the shares to be issued to the former
     holders of $2.16 Preferred Stock and to counsel for the objecting party
     will be issued upon the court's orders becoming final and nonappealable.
    
 
     The Company and MetLife Louisiana, the holder of all the Company's
     outstanding $2.20 Preferred Stock, entered into the Amended MetLife
     Memorandum pursuant to which MetLife Louisiana agreed to waive all existing
     mandatory redemption requirements of the $2.20 Preferred Stock, to consider
     all accrued and unpaid dividends thereon through February 9, 1994
     (aggregating approximately $21.2 million) to have been paid, to allow the
     Company to pay future dividends in Common Stock in lieu of cash, to waive
     or refrain from exercising other rights of the $2.20 Preferred Stock and to
     grant to the Company the MetLife Louisiana Option, pursuant to which the
     Company has the option to purchase, until February 9, 1997, all shares of
     the $2.20 Preferred Stock and Common Stock held by MetLife Louisiana, all
     in consideration for, among other things, the issuance by the Company to
     MetLife Louisiana of 1,900,075 shares of Common Stock. Such additional
     shares are also subject to the MetLife Louisiana Option. Until June 30,
     1994, the option exercise price is approximately $53.0 million, after
     giving effect to a reduction in the option price for the cash dividend paid
     on the $2.20 Preferred Stock in May 1994. The unexercised option price will
     be increased by 3% on the last day of each calendar quarter until December
     31, 1995, and by 3 1/2% on the last day of each quarter thereafter, and
     will be reduced by cash
 
                                       F-6
<PAGE>   71
 
     dividends paid on the $2.20 Preferred Stock after February 9, 1994. The
     Company will be required to pay dividends (in either cash or Common Stock)
     when due on the $2.20 Preferred Stock in order for the MetLife Louisiana
     Option to remain outstanding. In addition, the MetLife Louisiana Option is
     subject to certain minimum exercise requirements to remain outstanding
     beyond one year and two years; however, even if the net proceeds of the
     Offering are not sufficient to exercise the MetLife Louisiana Option in
     full, such net proceeds will be sufficient to satisfy all of the minimum
     exercise requirements.
 
     Had the Recapitalization occurred on January 1, 1993, the extraordinary
     loss on early extinguishment of debt would have been recognized during 1993
     and preferred stock dividend requirements for the three months ended March
     31, 1994 would have been reduced by approximately $308,000. There would be
     no other significant pro forma adjustments for such period.
 
(f)  Under the Offering, shares of outstanding capital stock of the Company are
     assumed to change as follows:

     The Company's primary shares outstanding on a pro forma basis will increase
     by 1,317,958 shares. Fully diluted shares will be reduced by a net
     1,150,238 shares as a result of the exercise of the MetLife Louisiana
     Option to reacquire 2,838,312 shares of the $2.20 Preferred Stock, each
     share of which is convertible by its terms into .8696 shares of Common
     Stock, or an aggregate of 2,468,196 shares of Common Stock. The
     reacquisition of the $2.20 Preferred Stock under the MetLife Louisiana
     Option would have eliminated preferred dividend requirements aggregating
     $6.2 million for the year ended December 31, 1993 and $1.6 million for the
     three months ended March 31, 1994.
    
 
(g)  Had the Recapitalization occurred on January 1, 1993, the Historical
     weighted average shares of Common Stock issued and outstanding for the
     three months ended March 31, 1994 would have been approximately 23,232,000
     shares, reflecting the pro forma issuance for the entire three month period
     ended March 31, 1994 of the 6,465,859 shares, the 131,956 shares and the
     1,900,075 shares referred to in (e) above.

                          INDEPENDENT AUDITORS' REPORT
 
Board of Directors and Stockholders
Tesoro Petroleum Corporation
 
     We have audited the accompanying consolidated balance sheets of Tesoro
Petroleum Corporation and subsidiaries as of December 31, 1993 and 1992, and the
related consolidated statements of operations, common stock and other
stockholders' equity and cash flows for the years ended December 31, 1993,
December 31, 1992 and September 30, 1991 and for the three-month period ended
December 31, 1991. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of Tesoro Petroleum Corporation
and subsidiaries at December 31, 1993 and 1992, and the results of their
operations and their cash flows for the years ended December 31, 1993, December
31, 1992 and September 30, 1991 and for the three-month period ended December
31, 1991, in conformity with generally accepted accounting principles.
 
     As discussed in Note A of Notes to Consolidated Financial Statements, in
1992 the Company changed its method of accounting for postretirement benefits
other than pensions and accounting for income taxes.

                          TESORO PETROLEUM CORPORATION
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
   (INFORMATION FOR THE THREE-MONTH PERIODS ENDED MARCH 31, 1993 AND 1994 IS
                                   UNAUDITED)
 
NOTE A -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Consolidation and Presentation
 
     The Consolidated Financial Statements include the accounts of Tesoro
Petroleum Corporation and its subsidiaries (collectively the "Company" or
"Tesoro") after elimination of significant intercompany balances and
transactions. Certain prior period amounts have been reclassified to conform
with the 1993 presentation.
 
     Effective January 1, 1992, the Company changed its fiscal year-end from
September 30 to December 31. Unless otherwise indicated, the information
contained herein addresses the Company's results of operations for the year
ended December 31, 1993, compared to the year ended December 31, 1992 and the
year ended September 30, 1991 and its financial condition as of December 31,
1993 and December 31, 1992. The results of operations for the three-month period
ended December 31, 1991 are discussed separately.
 
  Interim Reporting
 
     The interim consolidated financial statements are unaudited but, in the
opinion of management, incorporate all adjustments necessary for a fair
presentation of the Company's financial position and results of operations for
such interim periods. Such adjustments are of a normal recurring nature. The
results of operations for any interim period are not necessarily indicative of
results for the full year.
 
  Cash and Cash Equivalents and Short-Term Investments
 
     The Company considers all highly liquid investments purchased with a
maturity of three months or less to be cash equivalents. During 1992, the
Company began investing in short-term debt securities with original maturities
in excess of 90 days. These investments are classified as short-term investments
in the Company's Consolidated Balance Sheets. Cash equivalents and short-term
investments are stated at cost, which approximates market value. For information
regarding restricted cash, see Note I.
 
  Inventories
 
     The Company follows the lower of cost (last-in, first-out basis -- LIFO) or
market method for valuing inventories of crude oil and wholesale refined
products. All other inventories are valued principally at the lower of cost
(generally on a first-in, first-out or weighted average basis) or market.
 
  Futures and Options Hedge Contracts
 
     The Company uses commodity futures and options contracts primarily to hedge
the impact of price fluctuations on anticipated purchases of crude oil. Gains
and losses on commodity futures and options hedge contracts are deferred until
recognized in income when the related crude oil is charged to costs of sales.
 
  Property, Plant and Equipment
 
     The Company uses the full-cost method of accounting for oil and gas
properties. Under this method, all costs associated with property acquisition
and exploration and development activities are capitalized into cost centers
that are established on a country-by-country basis. For each cost center, the
capitalized costs are subject to a limitation so as not to exceed the present
value of future net revenues from estimated production of proved oil and gas
reserves net of income tax effect plus the lower of cost or estimated fair value
of unproved properties included in the cost center. Capitalized costs within a
cost center, together with estimates of costs for future development,
dismantlement and abandonment, are amortized on a unit-of-production method
using the proved oil and gas reserves for each cost center. The Company's
investment in certain oil and gas properties is excluded from the amortization
base until the properties are evaluated. No gain or loss is
 
                                      F-14
<PAGE>   79
 
recognized on the sale of oil and gas properties except in the case of the sale
of properties involving significant remaining reserves. Proceeds from the sale
of insignificant reserves and undeveloped properties are applied to reduce the
costs in the cost centers.
 
     Assets recorded under capital leases have been capitalized in accordance
with promulgations from the Financial Accounting Standards Board. Amortization
of such assets is recorded over the shorter of lease terms or useful lives under
methods which are consistent with the Company's depreciation policy for owned
assets.
 
     Depreciation of other property is provided using primarily the
straight-line method with rates based on the estimated useful lives of the
properties and with an estimated salvage value of 20% for refinery assets and
generally 10% for other assets. Amortization of leasehold improvements is
provided using the straight-line method over the term of the respective lease or
the useful life of the asset, whichever period is less.
 
  Postretirement Benefits Other Than Pensions
 
     The Company accounts for postretirement benefits other than pensions in
accordance with Statement of Financial Accounting Standards No. 106, "Employers'
Accounting for Postretirement Benefits Other Than Pensions" ("SFAS No. 106").
The projected future cost of providing postretirement benefits other than
pensions, such as health care and life insurance, are expensed as employees
render service instead of when benefits are paid. Prior to the adoption of SFAS
No. 106, the Company had expensed these benefits on a pay-as-you-go basis. The
adoption of SFAS No. 106, effective January 1, 1992, resulted in a net charge of
$21.6 million, or $1.54 per share, for the cumulative effect of the change in
accounting principle for periods prior to 1992, which were not restated. In
addition, the adoption of SFAS No. 106 resulted in an increase of $1.2 million,
or $.09 per share, in the 1992 net loss before cumulative effect of accounting
changes.
 
  Income Taxes
 
     The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS No.
109"). Deferred tax assets and liabilities are recognized for future tax
consequences attributable to differences between financial statement carrying
amounts of existing assets and liabilities and their respective tax bases.
Measurement of deferred tax assets and liabilities is based on enacted tax rates
expected to apply to taxable income in the years in which those temporary
differences are expected to be recovered or settled. Under SFAS No. 109, the
effect on deferred tax assets and liabilities of a change in tax rates is
recognized in income in the period that includes the enactment date. The Company
adopted SFAS No. 109 effective January 1, 1992 by recognizing a net benefit of
$1.0 million, or $.07 per share, for the cumulative effect of the accounting
change. Periods prior to 1992 were not restated. The adoption of SFAS No. 109
did not have a significant effect on 1992 results of operations.
 
  Environmental Expenditures
 
     Environmental expenditures that relate to current operations are expensed
or capitalized as appropriate. Expenditures that relate to an existing condition
caused by past operations, and which do not contribute to current or future
revenue generation, are expensed. Liabilities are recorded when environmental
assessments and/or remedial efforts are probable, and the cost can be reasonably
estimated. Generally, the timing of these accruals coincides with completion of
a feasibility study or the Company's commitment to a formal plan of action.
 
  Deferred Compensation
 
     Deferred compensation represents the excess of market value over the sales
price of restricted common stock awarded to certain employees of the Company.
The deferred compensation is being amortized over the period from the date of
award to the dates the shares become unrestricted (the period for which the
payment for services is being made).

  Earnings (Loss) Per Share
 
     Primary earnings (loss) per share is calculated on net earnings (loss)
after deducting dividend requirements on preferred stocks and is based on the
weighted average number of common and common equivalent shares outstanding
during the period. Fully diluted earnings (loss) per share is the same as
primary earnings (loss) per share since the assumed conversion of preferred
stocks to common shares would be anti-dilutive.
 
NOTE B -- RECAPITALIZATION
 
     In February 1994, the Company consummated exchange offers and adopted
amendments to its Restated Certificate of Incorporation pursuant to which the
Company's outstanding debt and preferred stock were restructured (the
"Recapitalization"). The Recapitalization has significantly improved the
Company's capital structure.
 
     The significant components of the Recapitalization, together with the
applicable accounting effects, were as follows:
 
     - The Company exchanged $44.1 million principal amount of new 13% Exchange
       Notes ("Exchange Notes") due December 1, 2000 for a like principal amount
       of 12 3/4% Subordinated Debentures ("Subordinated Debentures") due March
       15, 2001. This exchange satisfied the 1994 sinking fund requirement and,
       except for $.9 million, will satisfy sinking fund requirements for the
       Subordinated Debentures through 1997.
 
            The exchange of the Subordinated Debentures was accounted for as an
            early extinguishment of debt in the first quarter of 1994, resulting
            in a charge of $4.8 million as an extraordinary loss on this
            transaction, which represented the excess of the estimated market
            value of the Exchange Notes over the carrying value of the
            Subordinated Debentures. The carrying value of the Subordinated
            Debentures exchanged was reduced by applicable unamortized debt
            issue costs. No tax benefit was available to offset the
            extraordinary loss as the Company has provided a 100% valuation
            allowance to the extent of its deferred tax assets.
 
   
     - The 1,319,563 outstanding shares of the Company's $2.16 Cumulative
       Convertible Preferred Stock ("$2.16 Preferred Stock"), which had a $25
       per share liquidation preference, plus accrued and unpaid dividends
       aggregating $9.5 million at February 9, 1994, were reclassified into
       6,465,859 shares of the Common Stock. The Company also agreed to issue up
       to 131,956 shares of Common Stock on behalf of the holders of $2.16
       Preferred Stock and to pay $500,000 for certain of their legal fees and
       expenses in connection with the settlement of litigation related to the
       reclassification. The court awarded $500,000 and 73,913 shares of Common
       Stock for such legal fees and expenses, and 1,127 shares to counsel
       retained by a party objecting to the settlement, with the remaining
       56,916 shares to be issued to the former holders of $2.16 Preferred
       Stock. The shares awarded to counsel for the holders of $2.16 Preferred
       Stock have been issued; the shares to be issued to the former holders of
       $2.16 Preferred Stock and to counsel for the objecting party will be
       issued upon the court's orders becoming final and nonappealable.
    
 
   
            The issuance of the Common Stock in connection with the
            reclassification and settlement of litigation that was recorded in
            1994 resulted in an increase in Common Stock of approximately $1
            million, equal to the aggregate par value of the Common Stock
            issued, and an increase in additional paid-in capital of
            approximately $9 million.
    
 
     - The Company and MetLife Security Insurance Company of Louisiana ("MetLife
       Louisiana"), the holder of all of the Company's outstanding $2.20
       Cumulative Convertible Preferred Stock ("$2.20 Preferred Stock"), entered
       into an agreement (the "Amended MetLife Memorandum") with regard to the
       $2.20 Preferred Stock pursuant to which MetLife Louisiana agreed to waive
       all existing mandatory redemption requirements, to consider all accrued
       and unpaid dividends thereon (aggregating $21.2 million at February 9,
       1994) to have been paid, to allow the Company to pay future dividends on
       the $2.20 Preferred Stock in Common Stock in lieu of cash, to waive or
       refrain from exercising certain other rights of the $2.20 Preferred Stock
       and to grant to the Company a three-year option to purchase all of
       MetLife Louisiana's holdings of $2.20 Preferred Stock and Common Stock
       for approximately
 
                                      F-16
<PAGE>   81
 
       $53 million prior to June 30, 1994 after giving effect to the cash
       dividend paid in May 1994, all in consideration for, among other things,
       the issuance by the Company to MetLife Louisiana of 1,900,075 shares of
       Common Stock. Such additional shares are subject to the option granted by
       MetLife Louisiana. The unexercised option price will be increased by 3%
       on the last day of each calendar quarter until December 31, 1995, and by
       3 1/2% on the last day of each quarter thereafter, and will be reduced by
       cash dividends paid on the $2.20 Preferred Stock after February 9, 1994.
       The Company will be required to pay dividends (in either cash or Common
       Stock) when due on the $2.20 Preferred Stock in order for the option to
       remain outstanding. In addition, the option is subject to certain minimum
       exercise requirements to remain outstanding beyond one year and two
       years.
 
     These actions have resulted in the reclassification of the $2.20 Preferred
Stock into equity capital at its aggregate liquidation preference of $57.5
million and the recording of an increase in additional paid-in capital of
approximately $21 million in February 1994.
 
     The pro forma effects of the Recapitalization on the Company's results of
operations, assuming the Recapitalization had occurred on January 1, 1993, are
as follows (in millions except per share amounts):

NOTE D -- INVENTORIES
 
     Inventories valued by the LIFO method amounted to approximately $65.6
million, $63.0 million and $63.7 million at March 31, 1994, December 31, 1993
and 1992, respectively. At March 31, 1994 and December 31, 1993, inventories
valued using LIFO approximated replacement cost. At December 31, 1992
inventories valued using LIFO were lower than replacement cost by approximately
$9.6 million.
 
NOTE E -- PROPERTY, PLANT AND EQUIPMENT
 
     Effective May 1, 1992, the Company's subsidiaries, Tesoro Indonesia
Petroleum Company and Tesoro Tarakan Petroleum Company (collectively "Tesoro
Indonesia"), sold their 100% interest in two separate contracts of operations
with Pertamina, the state-owned petroleum company of Indonesia. The sales
included all of Tesoro Indonesia's interests in fixtures, wells, pipelines,
tanks, compressors, rigs and other equipment in
 
                                      F-19
<PAGE>   84
 
the contract areas, and inventories of crude oil and materials and supplies. The
consideration received by Tesoro Indonesia totaled $6.6 million in cash and the
assumption by the purchaser of liabilities of approximately $6.3 million and all
remaining expenditure commitments. During 1992, these sales transactions
resulted in pretax net gains to the Company of approximately $5.8 million after
related expenses.
 
     In 1992, the Company sold its corporate airplane and related assets for
$3.3 million in cash with no significant pretax gain to the Company. The Company
also sold certain oil and gas properties in South Texas for $2.1 million in
cash, which proceeds reduced the carrying value of the Company's oil and gas
properties and no gain or loss was recognized. In addition, the Company sold its
remaining drilling rigs for cash proceeds of $1.6 million resulting in a pretax
loss of $1.1 million during 1992.
 
     In January 1994, the Company sold its terminal facilities in Valdez, Alaska
for cash proceeds of $2.0 million and a note receivable of $3.0 million, which
resulted in a pretax gain to the Company of approximately $2.8 million during
the three months ended March 31, 1994.
 
NOTE F -- INVESTMENT IN TESORO BOLIVIA PETROLEUM COMPANY
 
     The Company's subsidiary, Tesoro Bolivia Petroleum Company ("Tesoro
Bolivia"), holds an interest in a joint venture agreement to explore for and
produce hydrocarbons in Bolivia. The joint venture has an agreement with the
Bolivian Government and YPFB, the Bolivian state-owned oil company, for
collection of receivables for sales of natural gas and condensate to YPFB, which
in turn sells the natural gas to the Republic of Argentina. The agreement
provides, among other things, that receipts from natural gas sales subsequent to
December 31, 1987 be placed in a restricted bank account ("Restricted Account")
from which only payments for investments and expenses in Bolivia can be made
until April 1992, or until cumulative deposits to the Restricted Account equal
$90.0 million. Cumulative deposits to the Restricted Account have totaled $90.0
million and receipts for natural gas sales are now free of restrictions to the
joint venture. The increase in the book value of this investment during 1993
represented earnings and cash invested in Tesoro Bolivia reduced by cash
received free of restrictions.

</TABLE>
 
     At December 31, 1993, the Company's net operating loss carryforwards were
approximately $71.1 million for regular tax and approximately $56.1 million for
alternative minimum tax. These tax loss carryforwards are available for future
years and, if not used, will begin to expire in the year 2004. Also at December
31, 1993, the Company had approximately $8.2 million of investment tax credits
and employee stock ownership credits available for carryover to subsequent
years. These credits, if not used, will begin to expire in the year 2001.
 
     If the Company has an "ownership change" as defined by the Internal Revenue
Code of 1986, the Company's use of its net operating loss carryforwards and
general business credits after such ownership change will be subject to an
annual limit. Under certain interpretations of existing Internal Revenue Service
(IRS) regulations, the Recapitalization, as discussed in Note B, resulted in an
ownership change. The Company has taken the position that an ownership change
under existing law did not occur prior to the recapitalization and did not occur
as a result thereof. Because there are substantial interpretive questions
concerning such IRS regulations and there is uncertainty as to events which may
occur after the Recapitalization, there can be no assurance that an ownership
change did not occur as a result of the Recapitalization or will not occur as a
result of future events. If an ownership change is ultimately deemed to have
occurred at the time of the Recapitalization, the Company's use of its net
operating loss carryforwards and general business credits at February 9, 1994
would be limited to approximately $14.5 million per year.

     Based on the closing market price, the fair value of the Subordinated
Debentures, exclusive of accrued interest, was approximately $108.3 million at
December 31, 1993 and approximately $64.6 million at March 31, 1994 and the fair
value of the Exchange Notes, exclusive of accrued interest, was approximately
$44.9 million at March 31, 1994. The carrying value of the other long-term debt
and obligations approximated the Company's estimate of the fair value of such
items.
 
     As discussed in Note B, approximately four years of sinking fund
requirements on the Subordinated Debentures were satisfied by the exchange offer
included in the Recapitalization. After giving effect to the Recapitalization,
sinking fund requirements and aggregate maturities of long-term debt and
obligations for each of the five years following December 31, 1993 are as

  Letter of Credit Requirements
 
   
     On October 29, 1993, the Company elected to terminate its secured Letter of
Credit Facility Agreement ("Credit Facility") dated July 27, 1989, which was
scheduled to expire in March 1994 and which provided for the issuance of up to
$40 million in letters of credit at the date of termination. In the latter half
of 1993, the Company negotiated several interim credit arrangements
collateralized by either cash or inventory to permit the Company to secure the
purchases of crude oil feedstocks and to meet other operating and corporate
credit requirements. With respect to these interim credit arrangements, the
Company entered into several uncommitted letter of credit facilities which
provide for the issuance of letters of credit on a cash-secured basis. Total
availability pursuant to the uncommitted letter of credit arrangements was in
excess of $80 million at March 31, 1994.
    
 
     At December 31, 1993, the Company had arranged for the issuance of $25
million of outstanding letters of credit which were secured by restricted cash
deposits. At 1992 year-end, under the terms of the previous Credit Facility, the
Company was required to maintain a minimum $30 million cash balance and
specified levels of equity and working capital.
 
                                      F-23
<PAGE>   88
 
     In addition, effective September 30, 1993, the Company entered into a
waiver and substitution of collateral agreement ("Substitution Agreement") with
the State of Alaska, the Company's largest supplier of crude oil. Under the
Substitution Agreement, the Company pledged the capital stock of Tesoro Alaska
Petroleum Company ("Tesoro Alaska"), a wholly-owned subsidiary of the Company,
and substantially all of its crude oil and refined product inventory in Alaska
to secure its purchases of royalty crude oil. The Substitution Agreement allowed
the Company to reduce its letter of credit requirements to $25 million as of
December 31, 1993. This agreement extended through January 1, 1995 and contained
various covenants and restrictions customary to inventory financing
transactions.
 
     At March 31, 1994 and December 31, 1993, the Company had restricted cash of
$26.6 million and $25.4 million, respectively, for use as collateral for
outstanding letters of credit under the interim financing arrangements.
 
  Exploration and Production Financing
 
     Effective October 29, 1993, Tesoro Exploration and Production Company
("Tesoro E&P"), a wholly-owned subsidiary of the Company, entered into a $30
million reducing revolving credit facility ("E&P Facility") secured by the
capital stock of Tesoro E&P and its natural gas properties in the Bob West Field
in South Texas. At December 31, 1993, $5.0 million was outstanding under this
facility.
 
     The E&P Facility, which was scheduled to expire December 31, 1996, was
guaranteed by the Company, contained certain financial covenants that were to be
maintained by Tesoro E&P and bore interest at prime plus 1% per annum or, at
Tesoro E&P's option, Libor plus 2.5% per annum. The E&P Facility contains
restrictions that prohibit borrowings under the facility to be used by Tesoro
E&P or the Company for debt service, including interest and principal on the
Company's 12 3/4% Subordinated Debentures, or for payment of common or preferred
dividends.
 
  Revolving Credit Facility
 
     During April 1994, the Company entered into a new three-year $125 million
corporate revolving credit facility ("Revolving Credit Facility") with a
consortium of ten banks. The Revolving Credit Facility, which is subject to a
borrowing base, provides for (i) the issuance of letters of credit up to the
full amount of the borrowing base as calculated, but not to exceed $125 million
and (ii) cash borrowings up to the amount of the borrowing base attributable to
domestic oil and gas reserves. Outstanding obligations under the Revolving
Credit Facility are secured by liens on substantially all of the Company's trade
accounts receivable and product inventory and mortgages on the Refinery and the
Company's South Texas natural gas reserves.
 
   
     Letters of credit available under the Revolving Credit Facility are limited
to a borrowing base calculation. As of June 10, 1994, the borrowing base, which
is comprised of eligible accounts receivable, inventory and domestic oil and gas
reserves, was approximately $95 million. As of June 10, 1994, the Company had
outstanding letters of credit under the new facility of $39 million, with a
remaining unused availability of $56 million. Cash borrowings are limited to the
amount of the oil and gas reserve component of the borrowing base, which has
initially been determined to be approximately $32 million. Cash borrowings under
the Revolving Credit Facility will reduce the availability of letters of credit
on a dollar-for-dollar basis; however, letter of credit issuances will not
reduce cash borrowing availability unless the aggregate dollar amount of
outstanding letters of credit exceeds the sum of the accounts receivable and
inventory components of the borrowing base.
    
 
     Under the terms of the Revolving Credit Facility, the Company is required
to maintain specified levels of working capital, tangible net worth and cash
flow. Among other matters, the Revolving Credit Facility has certain
restrictions with respect to (i) capital expenditures, (ii) incurrence of
additional indebtedness, and (iii) dividends on capital stock. The Revolving
Credit Facility contains other covenants customary in credit arrangements of
this kind.
 
     The Revolving Credit Facility replaced certain interim financing
arrangements that the Company had been using since the termination of its prior
letter of credit facility in October 1993. The interim financing
 
                                      F-24
<PAGE>   89
 
arrangements that were cancelled in conjunction with the completion of the new
Revolving Credit Facility included the E&P Facility and the Substitution
Agreement discussed above. In addition, the completion of the Revolving Credit
Facility provides the Company significant flexibility in the investment of
excess cash balances, as the Company is no longer required to maintain minimum
cash balances or to cash secure letters of credit.
 
     During May 1994, the National Bank of Alaska and the Alaska Industrial
Development & Export Authority agreed to provide a loan to the Company of up to
$15 million of the $24 million cost of the vacuum unit for the Refinery (the
"Vacuum Unit Loan"). The Vacuum Unit Loan will mature on January 1, 2002, will
require 28 equal quarterly payments beginning April 1, 1995 and will bear
interest at the unsecured 90-day commercial paper rate, adjusted quarterly, plus
2.6% per annum for two-thirds of the amount borrowed and at the National Bank of
Alaska floating prime rate plus 1/4 of 1% per annum for the remainder. The
Vacuum Unit Loan is secured by a first lien on the Refinery.
 
  12 3/4% Subordinated Debt and 13% Exchange Notes
 
     In 1983, the Company issued $120 million of 12 3/4% Subordinated Debentures
at a price of 84.559% of the principal amount, due March 15, 2001. The
debentures are redeemable at the option of the Company at 100% of principal
amount plus accrued interest. Sinking fund payments sufficient to retire $11.25
million principal amount of debentures annually commenced on March 15, 1993. The
Company satisfied the initial sinking fund requirement by purchasing $11.25
million principal amount of debentures at market value on January 26, 1993. The
exchange of $44.1 million principal amount of Subordinated Debentures for
Exchange Notes in February 1994 satisfied the 1994 sinking fund requirement and,
except for $.9 million, satisfied sinking fund requirements for the Subordinated
Debentures through 1997 (see Note B). At March 31, 1994, December 31, 1993 and
December 31, 1992, subordinated debt amounted to $58.6 million (net of discount
of $6.0 million), $98.2 million (net of discount of $10.6 million) and $107.5
million (net of discount of $12.5 million), respectively. The indenture contains
restrictions on payment of dividends on the Company's common stock and purchases
or redemptions of common or preferred stocks. Due to losses which have been
incurred, as of December 31, 1993, the Company must generate approximately $131
million of future net earnings applicable to common stock or from the issuance
of capital stock before future dividends can be paid on common stock or before
purchases or redemptions can be made of common or preferred stocks.
 
     As part of the Recapitalization discussed in Note B, in February 1994,
Subordinated Debentures in the principal amount of $44.1 million were exchanged
for a like amount of new 13% Exchange Notes. The Exchange Notes mature on
December 1, 2000, and have no sinking fund requirements. The Exchange Notes are
redeemable at the option of the Company at 100% of principal amount plus accrued
interest except that no optional redemption may be made unless an equal
principal amount of, or all the outstanding, Subordinated Debentures, are
concurrently redeemed. The Exchange Notes rank pari passu with the other senior
debt of the Company and with the Subordinated Debentures, and senior in right of
payment of the obligation to the State of Alaska (discussed below) and all other
subordinated indebtedness of the Company. The indenture governing the Exchange
Notes contains limitations on dividends which are less restrictive than the
limitation under the Subordinated Debentures. For information on the pro forma
effects of the exchange, see Note B.
 
  State of Alaska
 
     In January 1993, the Company and its subsidiary, Tesoro Alaska Petroleum
Company ("Tesoro Alaska"), entered into an agreement ("Agreement") with the
State of Alaska ("State") that settled Tesoro Alaska's contractual dispute with
the State. In addition to $62 million accrued through September 30, 1992, a
charge of $10.5 million for the settlement was included in the Company's
operations during the fourth quarter of 1992.
 
     Under the Agreement, Tesoro Alaska paid the State $10.3 million in January
1993 and is obligated to make variable monthly payments to the State through
December 2001 based on a per barrel charge that is currently 16 cents and
increases to 33 cents on the volume of feedstock processed at the Company's
Alaska refinery. In 1993, the Company's variable payments to the State totaled
$2.6 million. In January 2002, Tesoro
 
                                      F-25
<PAGE>   90
 
Alaska is obligated to pay the State $60 million; provided, however, that such
payment may be deferred indefinitely by continuing the variable monthly payments
to the State beginning at 34 cents per barrel for 2002 and increasing one cent
per barrel annually thereafter. Variable monthly payments made after December
2001 will not reduce the $60 million obligation to the State. The imputed rate
of interest used by the Company on the $60 million obligation was 13%. The $60
million obligation is evidenced by a security bond, and the bond and the
throughput barrel obligations are secured by a second mortgage on the Company's
Alaska refinery. Tesoro Alaska's obligations under the Agreement and the
mortgage are subordinated to current and future senior debt of up to $175
million plus any indebtedness incurred in the future to improve the Company's
Alaska refinery.
 
     The State's claim against Tesoro Alaska arose out of certain provisions in
present and past contracts with the State that required Tesoro Alaska to pay the
State additional retroactive amounts if the State prevailed in litigation
against the producers of North Slope crude oil ("Producers"). As a result of
settlements between the State and the Producers, the State claimed that the
royalty oil it sold Tesoro Alaska and others was undervalued to the extent that
the Producers undervalued their oil.
 
  Department of Energy
 
     A Consent Order entered into by the Company with the Department of Energy
("DOE") in 1989 settled all issues relating to the Company's compliance with
federal petroleum price and allocation regulations from 1973 through decontrol
in 1981. Through March 31, 1994, the Company had paid $41.7 million to the DOE
since 1989. The Company's remaining obligation is to pay $13.2 million,
exclusive of interest at 6%, over the next eight years.
 
  Industrial Revenue Bonds and Other
 
     The industrial revenue bonds mature in 1998 and require semiannual payments
of approximately $365,000. The bonds bear interest at a variable rate (4 1/2% at
December 31, 1993) which is equal to 75% of the National Bank of Alaska's prime
rate. The bonds are collateralized by the Company's Alaska refinery sulphur
recovery unit which had a carrying value of approximately $6.9 million at
December 31, 1993.
 
  Capital Lease Obligations
 
     The Company is the lessee of certain buildings and equipment under capital
leases with remaining lease terms of 4 to 25 years. These buildings and
equipment are used in the Company's convenience store operations in Alaska. The
assets and liabilities under capital leases are recorded at the present value of
the minimum lease payments. Property, plant and equipment at December 31, 1993
included assets held under capital leases of $6.0 million with a net book value
of $2.6 million.

  Postretirement Benefits Other than Pensions
 
     In addition to providing pension benefits, the Company provides health care
and life insurance benefits to retirees and eligible dependents who were
participating in the Company's group insurance program at retirement. These
benefits are provided through unfunded defined benefit plans. The health care
plans are contributory, with retiree contributions adjusted periodically, and
contain other cost-sharing features such as deductibles and coinsurance. The
life insurance plan is noncontributory.
 
     As discussed in Note A, the Company adopted SFAS No. 106 effective January
1, 1992 and incurred a net charge of $21.6 million ($16.1 million for health
care benefits and $5.5 million for life insurance benefits) for the cumulative
effect of the change in accounting principle. The components of net periodic
postretirement benefits expense, other than pensions, for 1992 and 1993 included

     The weighted average annual assumed rate of increase in the per capita cost
of covered health care benefits was assumed to be 12% for 1994, decreasing
gradually to 7% by the year 2010 and remaining at that level thereafter. This
health care cost trend rate assumption has a significant effect on the amount of
the obligation and periodic cost reported. For example, an increase in the
assumed health care cost trend rates by one percentage point in each year would
increase the accumulated postretirement obligation as of December 31, 1993 by
$2.9 million and the aggregate of service cost and interest cost components of
net periodic postretirement benefits for the year then ended by $.4 million.
 
     Actuarial assumptions used to measure the accumulated postretirement
benefit obligation at December 31, 1993 included a discount rate of 7% and a
compensation rate increase of 4 1/2%. At December 31, 1992, the discount rate
was 8 1/2% and the compensation rate increase was 6%.
 
  Thrift Plan
 
     The Company's employee thrift plan provides for contributions by eligible
employees into designated investment funds with a matching contribution by the
Company of 50% of the employee's basic contribution. The Company's contributions
amounted to $482,000, $474,000 and $439,000 during 1993, 1992 and 1991,
respectively. For the three months ended March 31, 1994, March 31, 1993 and
December 31, 1991, the Company's contributions amounted to $113,000, $102,000
and $107,000, respectively.
 
  Cost Reduction Program and Other Employee Terminations
 
     In addition to the ESP settlement losses and other benefits and the
retirement plan curtailment gain discussed above, during 1992 the Company
incurred charges of $6.6 million for expenses to implement a cost reduction
program and other employee terminations.

  Gas Purchase and Sales Contract
 
     The Company is selling a portion of the gas from its Bob West Field to
Tennessee Gas Pipeline Company ("Tennessee Gas") under a Gas Purchase and Sales
Agreement (the "Tennessee Gas Contract") which provides that the price of gas
shall be the maximum price as calculated in accordance with Section 102(b)(2)
(the "Contract Price") of the Natural Gas Policy Act of 1978 (the "NGPA").
 
     Tennessee Gas filed suit against the Company alleging that the Tennessee
Gas Contract is not applicable to the Company's properties and that the gas
sales price should be the price calculated under the provisions of Section 101
of the NGPA rather than the Contract Price. During March 1994, the Contract
Price was $7.84 per Mcf, the Section 101 price was $4.58 per Mcf and the average
spot market price was $2.09 per Mcf. Tennessee Gas also claimed that the
contract should be considered an "output contract" under Section 2.306 of the
Texas Business and Commerce Code and that the increases in volumes tendered
under the contract exceeded those allowable for an output contract. The Company
continues to receive payment from Tennessee Gas based on the Contract Price for
all volumes that are subject to the contract under the Company's interpretation.
 
     The District Court trial judge returned a verdict in favor of the Company
on all issues. On appeal by Tennessee Gas, the Court of Appeals affirmed the
validity of the Tennessee Gas Contract as to the Company's properties and held
that the price payable by Tennessee Gas for the gas was the Contract Price. The
Court of Appeals remanded the case to the trial court based on its determination
(i) that the Tennessee Gas Contract was an output contract and (ii) that a fact
issue existed as to whether the increases in the volumes of gas tendered to
Tennessee Gas under the contract were made in bad faith or were unreasonably
disproportionate to prior tenders. The Company is seeking review of the
appellate court ruling on the output contract issue in the Supreme Court of
Texas. Tennessee Gas is seeking review of the appellate court ruling denying the
remaining Tennessee Gas claims in the Supreme Court of Texas.
 
     Although the outcome of any litigation is uncertain, management, based upon
advice from outside legal counsel, is confident that the decision of the trial
and appellate courts will ultimately be upheld as to the validity of the
Tennessee Gas Contract and the Contract Price. Therefore, if the Supreme Court
of Texas does not grant the Company's petition for writ of error and affirms the
appellate court ruling, the Company believes that the only issue for trial
should be whether the increases in the volumes of gas tendered to Tennessee Gas
from the Company's properties were made in bad faith or were unreasonably
disproportionate. The appellate
 
                                      F-30
<PAGE>   95
 
   
court decision was the first reported decision in Texas holding that a
take-or-pay contract was an output contract. As a result, it is not clear what
standard the trial court would be required to apply in determining whether the
increases were in bad faith or unreasonably disproportionate. The appellate
court acknowledged in its opinion that the standards used in evaluating other
kinds of output contracts would not be appropriate in this context. The Company
believes that the appropriate standard would be whether the development of the
field was undertaken in a manner that a prudent operator would have undertaken
in the absence of an above-market sales price. Under that standard, the Company
believes that, if this issue is tried, the development of its gas properties and
the resulting increases in volumes tendered to Tennessee Gas will be found to
have been reasonable and in good faith. Accordingly, the Company has recognized
revenues, net of production taxes and marketing charges, for natural gas sales
through March 31, 1994, under the Tennessee Gas Contract based on the Contract
Price, which net revenues aggregated $21.1 million more than the Section 101
prices and $38.9 million in excess of the spot market prices. If Tennessee Gas
ultimately prevails in this litigation, the Company could be required to return
to Tennessee Gas the difference between the spot market price for gas and the
Contract Price, plus interest, if awarded by the court.
    
 
   
     On June 7, 1994, Tennessee Gas filed a motion with the court requesting
that the court permit Tennessee Gas to pay the difference between the Contract
Price and the spot market price into the registry of the court on a monthly
basis in lieu of paying the Company the Contract Price or, in the alternative,
that the court require the Company to post a bond to secure any amount which the
Company might owe Tennessee Gas if Tennessee Gas were to ultimately prevail in
the litigation. The Company believes that Tennessee Gas is not entitled to avoid
paying the Contract Price by such monthly payments but that Tennessee Gas may be
able to cease making payments above spot market prices pending the ultimate
outcome of the litigation if it posts a satisfactory bond. The Company does not
believe that the court will require the Company to post a bond. If the court
were to permit Tennessee Gas to reduce its payments to the Company to spot
market prices pending resolution of the litigation, the Company's cash flow
would be substantially reduced. The Company believes that at present spot market
prices the Company would be able to fund its capital expenditure program and
comply with its financial covenants under the Revolving Credit Facility if the
court were to grant the request of Tennessee Gas.
    
 
   
     An adverse judgment in this case could have a material adverse effect on
the Company. For further information concerning the effect of the Tennessee Gas
Contract on certain of the Company's revenues and cash flows, see Note P.
    
 
   
  Other
    
 
     In March 1992, the Company received a Compliance Order and Notice of
Violation from the U.S. Environmental Protection Agency ("EPA") alleging
possible violations by the Company of the New Source Performance Standards under
the Clean Air Act at its Alaska refinery. The Company is continuing in its
efforts to resolve these issues with the EPA; however, no final resolution has
been reached. The Company believes that the ultimate resolution of this matter
will not have a material adverse effect upon the Company's business or financial
condition.
 
     The Company is subject to extensive federal, state and local environmental
laws and regulations. These laws, which are constantly changing, regulate the
discharge of materials into the environment and may require the Company to
remove or mitigate the environmental effects of the disposal or release of
petroleum or chemical substances at various sites. The Company is currently
involved with two waste disposal sites in Louisiana at which it has been named a
potentially responsible party under the Federal Superfund law. Although this law
might impose joint and several liability upon each party at any site, the extent
of the Company's allocated financial contribution to the cleanup of these sites
is expected to be limited based on the number of companies and the volumes of
waste involved. At each site, a number of large companies have also been named
as potentially responsible parties and are expected to cooperate in the cleanup.
The Company is also involved in remedial response and has incurred cleanup
expenditures associated with environmental matters at a number of other sites
including certain of its own properties.
 
                                      F-31
<PAGE>   96
 
     At March 31, 1994, the Company had accrued $6.0 million for environmental
costs. Based on currently available information, including the participation of
other parties or former owners in remediation actions, the Company believes
these accruals are adequate. Conditions which require additional expenditures
may exist for various Company sites, including, but not limited to, the
Company's refinery, service stations (current and closed locations) and
petroleum product terminals, and for compliance with the Clean Air Act. The
amount of such future expenditures cannot presently be determined by the
Company.
 
     The Company transports its crude oil and a substantial portion of its
refined products utilizing Kenai Pipe Line Company's ("KPL") pipeline and marine
terminal facilities in Kenai, Alaska. In March 1994, KPL filed a revised tariff
with the Federal Energy Regulatory Commission ("FERC") for dock loading
services, which would have increased the Company's annual cost of transporting
products through KPL's facilities from $1.2 million to $11.2 million, or an
increase of $10 million per year. Following the FERC's rejection of KPL's tariff
and the commencement of negotiations for the purchase by the Company of the dock
facilities, KPL filed a temporary tariff that would increase the Company's
annual cost by approximately $1.5 million. The negotiations between the Company
and KPL are continuing. The Company believes that the ultimate resolution of
this matter will not have a material adverse effect upon the financial condition
or results of operations of the Company.
 
     In May 1994, a former customer threatened to file suit against the Company
for a refund in the amount of approximately $1.2 million, plus interest of
approximately $4.4 million and attorney's fees, related to two gasoline
purchases from the Company in 1979. The customer also alleges entitlement to
treble damages and punitive damages in the aggregate amount of $16.8 million.
The refund claim is based on allegations that the Company renegotiated the
acquisition price of gasoline sold to the customer and failed to pass on the
benefit of the renegotiated price to the customer in violation of Department of
Energy price and allocation controls then in effect. The Company believes the
claim is without merit and anticipates that the ultimate resolution of this
matter will not have a material adverse effect on the Company.
 
NOTE L -- REDEEMABLE PREFERRED STOCK
 
     In March 1983, the Company sold 2,875,000 shares of a series of redeemable
preferred stock at $20 per share. The stock is held by MetLife Louisiana, which
is a subsidiary of Metropolitan Life Insurance Company. The class of stock, of
which there were 2,875,000 shares authorized, issued and outstanding at December
31, 1993 and 1992, has been designated the $2.20 Cumulative Convertible
Preferred Stock ("$2.20 Preferred Stock"). This series has one vote per share,
is convertible into .8696 shares of Common Stock for each share of Preferred
Stock, has a stated value of $1 per share and a liquidation price of $20 per
share plus accrued dividends. The $2.20 Preferred Stock ranks in parity with the
$2.16 Cumulative Convertible Preferred Stock as to liquidation and dividends.
 
     The redeemable preferred stock was recorded at fair value on the date of
issuance less issue costs. The excess of the redemption value over the carrying
value is being accreted by periodic charges to retained earnings over the life
of the issue. During 1993 and 1992, the carrying value of the redeemable
preferred stock was increased for mandatorily redeemable accumulated dividends,
not declared or paid, by charges to retained earnings. As of December 31, 1993,
dividends in arrears on the $2.20 Preferred Stock amounted to approximately
$19.8 million, or $6.875 per share.
 
     As discussed in Note B, in February 1994, the agreement between the Company
and MetLife Louisiana was amended with regard to such preferred shares to waive
all existing mandatory redemption requirements, to consider all accrued and
unpaid dividends (aggregating $21.2 million at February 9, 1994) to have been
paid, to allow the Company to pay future dividends in Common Stock in lieu of
cash, to waive or refrain from exercising other rights of the $2.20 Preferred
Stock and to grant to the Company an option to purchase, during the next three
years, all shares of the $2.20 Preferred Stock and Common Stock held by MetLife
Louisiana for approximately $53 million (amount at February 9, 1994, increasing
by 12% to 14% annually) subject to certain conditions, in consideration for,
among other things, the issuance by the Company to MetLife Louisiana of
1,900,075 shares of Common Stock. Such additional shares are subject to the
option granted by MetLife Louisiana. After giving effect to the
Recapitalization, MetLife Louisiana's Common and Preferred

     For information regarding the effects of the Recapitalization on the
Company's Common Stock and Other Stockholders' Equity, refer to Note B.
 
  $2.16 Cumulative Convertible Preferred Stock
 
     The Company has designated a class of preferred stock, of which there were
1,319,563 shares outstanding at December 31, 1993 and 1992 and 200,000 shares
reserved for the granting of options under a stock option plan of the Company.
This class, designated the $2.16 Cumulative Convertible Preferred Stock ("$2.16
Preferred Stock"), has voting rights, is convertible into Common Stock at the
rate of 1.7241 shares of Common Stock for each share of Preferred Stock, has a
stated value of $1 per share and a liquidation value of $25 per share, and is
repurchasable at the option of the Company at liquidation value plus accrued
dividends. The $2.16 Preferred Stock ranks in parity with the $2.20 Preferred
Stock as to liquidation and dividends.
 
     During 1993 and 1992, the liability for accumulated dividends, not declared
or paid, on the $2.16 Preferred Stock was accrued by charges to retained
earnings. As of December 31, 1993, dividends in arrears on the $2.16 Preferred
Stock amounted to approximately $8.9 million, or $6.75 per share.
 
     As discussed in Note B, in February 1994, the outstanding shares of the
Company's $2.16 Preferred Stock, plus accrued and unpaid dividends thereon
(aggregating $9.5 million at February 9, 1994), were reclassified into shares of
the Company's Common Stock.
 
  Incentive Stock Plans
 
     The Company's Amended Incentive Stock Plan of 1982 (the "1982 Plan")
provides for the granting of stock incentives in the form of stock options,
stock appreciation rights and stock awards to officers and key employees. The
stock options are exercisable in accordance with the option plans and expire no
later than ten years from the date of grant. Stock appreciation rights are
exercisable in three to five annual installments, normally beginning with the
first anniversary date of the grant, and expire ten years from the date of
grant. The stock appreciation rights entitle the employee to receive, without
payment to the Company, the incremental increase in market value of the related
stock from date of grant to date of exercise, payable in cash. Related
compensation expense is charged to earnings over periods earned. During 1993,
1992 and 1991 and the three months ended March 31, 1993 and December 31, 1991,
no compensation expense was recognized since the market value of the Company's
Common Stock remained below the exercise price. During the three months ended
March 31, 1994, compensation expense related to the stock appreciation rights
was approximately $29,000, as a result of the market price of the related stock
exceeding the exercise price of the stock appreciation rights. Stock awards
totaling 83,015 common shares, 100,000 common shares and 12,000 common shares
were granted at par value to certain employees of the Company in 1993, 1992 and
1991, respectively. Related compensation expense is charged to earnings over the
periods that the shares are earned and amounted to $572,000, $142,000, $135,000
and $28,000 for 1993, 1992 and 1991 and the three months ended December 31,
1991, respectively, and $23,000 and $29,000, respectively, for the three months
ended March 31, 1994 and 1993.
 
     On February 9, 1994, the Company's shareholders approved the Executive
Long-Term Incentive Plan (the "1993 Plan") which permits the issuance of awards
in a variety of forms, including restricted stock, incentive stock options,
nonqualified stock options, stock appreciation rights and performance share and
performance unit awards. The 1993 Plan provides for the grant of up to 1,250,000
shares of the Company's Common Stock and, unless earlier terminated, will expire
as to the issuance of awards on September 15, 2003. No awards have been made
under the 1993 Plan.
 
     At March 31, 1994, December 31, 1993 and 1992 and September 30, 1991, the
Company had 1,250,000, 60,002, 392,566 and 852,381 unoptioned shares,
respectively, available for granting of options, rights and awards under the
1982 Plan and the 1993 Plan and 5,067,117, 6,064,809, 6,084,809 and 6,093,231
shares of unissued Common Stock, respectively, reserved for conversion of
preferred stock and the Plans. During 1988,
 
                                      F-33
<PAGE>   98
 
an amendment to the 1982 Plan was approved which increased the number of shares
of Common Stock which may be granted or transferred from 1,500,000 to 2,000,000.
The additional shares were registered with the Securities and Exchange
Commission during 1994. The 1982 Plan expired on February 24, 1994 as to
issuance of options, rights and awards; however, grants made before such date
that have not been fully exercised will remain outstanding pursuant to their
terms.

  Preferred Stock Purchase Rights
 
   
     In November 1985, the Company's Board of Directors declared a distribution
of one preferred stock purchase right for each share of the Company's Common
Stock. Each right will entitle the holder to buy 1/100 of a share of a newly
authorized Series A Participating Preferred Stock at an exercise price of $35
per right. The rights become exercisable on the tenth day after public
announcement that a person or group has acquired 20% or more of the Company's
Common Stock. The rights may be redeemed by the Company prior to becoming
exercisable by action of the Board of Directors at a redemption price of $.05
per right. If the Company is acquired by any person after the rights become
exercisable, each right will entitle its holder to purchase stock of the
acquiring company having a market value of twice the exercise price of each
right. At December 31, 1993, and March 31, 1994, there were 14,089,236 and
22,456,968, respectively, rights outstanding which will expire in December 1995.

     The 1992 first quarter included charges of $20.6 million for the cumulative
effect of accounting changes, $2.4 million for a cost reduction program and $1.0
million for asset write-downs. The 1992 third quarter included a $5.8 million
gain from the sales of the Company's Indonesian operations. The fourth quarter
of 1992 included revenues and operating profit of $5.4 million ($.38 per share)
resulting from a change in estimate of the Company's revenues from natural gas
production in the South Texas field (see Note K) and additional charges of $10.5
million for the settlement with the State of Alaska and $5.6 million for the
cost reduction program and other employee terminations.
 
     The 1993 second quarter and fourth quarters included benefits of $3.0
million and $5.2 million, respectively, for resolution of several state tax
issues. A $5.0 million charge for an inventory erosion was recorded in the 1993
third quarter. Included in the 1993 fourth quarter, however, was a $5.7 million
offset to the inventory adjustment taken earlier in the year. Inventory levels
at the 1993 year-end were greater than projected earlier in the year due to
changing market conditions. The 1993 fourth quarter benefited from the decline
in crude oil prices, while the Company's refined product margins held steady or
improved.
 
     The 1994 first quarter included an extraordinary loss on early
extinguishment of debt as a result of $44.1 million principal amount of
Subordinated Debentures being exchanged for a like amount of Exchange Notes as
part of the Recapitalization and a gain of $2.8 million from the sale of the
Company's Valdez, Alaska terminal.

     The Company's investment in oil and gas properties included $2.0 million in
unevaluated properties which have been excluded from the amortization base as of
December 31, 1993. The Company anticipates that the majority of these costs,
substantially all of which were incurred in 1993, will be included in the
amortization base during 1994.

 Standardized Measure of Discounted Future Net Cash Flows Relating to Proved
 Reserves (Unaudited)
 
     The following table sets forth the computation of the standardized measure
of discounted future net cash flows relating to proved reserves and the changes
in such cash flows in accordance with Statement of Financial Accounting
Standards No. 69 ("SFAS No. 69"). The standardized measure is the estimated
excess future cash inflows from proved reserves less estimated future production
and development costs, estimated future income taxes and a discount factor.
Future cash inflows represent expected revenues from production of year-end
quantities of proved reserves based on year-end prices and any fixed and
determinable future escalation provided by contractual arrangements in existence
at year-end. Escalation based on inflation, federal regulatory changes and
supply and demand are not considered. Estimated future production costs related
to year-end reserves are based on year-end costs. Such costs include, but are
not limited to, production taxes and direct operating costs. Inflation and other
anticipatory costs are not considered until the actual cost change takes effect.
Estimated future income tax expenses are computed using the appropriate year-end
statutory tax rates. Consideration is given for the effects of permanent
differences, tax credits and allowances. A discount rate of 10% is applied to
the annual future net cash flows after income taxes.
 
     The methodology and assumptions used in calculating the standardized
measure are those required by SFAS No. 69. The standardized measure is not
intended to be representative of the fair market value of the Company's proved
reserves. The calculations of revenues and costs do not necessarily represent
the amounts to be received or expended by the Company.
 
     As indicated in Note K, certain of the Company's South Texas production
activities are involved in litigation pertaining to a natural gas sales contract
with Tennessee Gas. Although the outcome of any litigation is uncertain, based
upon advice from outside legal counsel, management believes that the Company
will ultimately prevail in this dispute. Accordingly, the Company has based its
calculation of the standardized measure of discounted future net cash flows on
the Contract Price which it is currently receiving. However, if Tennessee Gas
were to prevail, the impact on the Company's future revenues and cash flows
would be significant. Based on the Contract Price, the standardized measure of
discounted future net cash flows relating to proved reserves in the United
States at December 31, 1993 was $103 million, compared to $59 million at spot
market prices.

  Reserve Quantity Information (Unaudited)
 
     The following estimates of the Company's proved oil and gas reserves are
based on evaluations prepared by Netherland, Sewell & Associates, Inc. (except
for estimates of reserves at December 31, 1991 for properties in Bolivia and for
all periods for properties in Indonesia, which estimates were prepared by the
Company's in-house engineers). Reserves were estimated in accordance with
guidelines established by the Securities and Exchange Commission and Financial
Accounting Standards Board, which require that reserve estimates be prepared
under existing economic and operating conditions with no provision for price and
cost escalations except by contractual arrangements.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
    
 
     Section 145 of the Delaware General Corporation Law empowers the Company
to, and the bylaws of the Company provide that it shall, to the full extent
authorized or permitted by the laws of the State of Delaware, indemnify any
person who is made, or threatened to be made, a party to an action, suit or
proceeding (whether civil, criminal, administrative or investigative) by reason
of the fact that he, his testator or intestate is or was a director, officer or
employee of the Company, respectively, or serves or served any other enterprise
at the request of the Company.
 
     Article Ninth of the Company's Certificate of Incorporation provides that
no director of the Company will be personally liable to the Company or its
stockholders for monetary damages for breach of fiduciary duty by such directors
as a director; provided, however, that such article will not eliminate or limit
liability of a director to the extent provided by applicable law (i) for any
breach of the director's duty of loyalty to the Company or its stockholders,
(ii) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of the law, (iii) under Section 174 of the
General Corporation Law of the State of Delaware, or (iv) for any transaction
from which the director derived an improper personal benefit. The effect of this
provision is to eliminate the personal liability of a director to the Company
and its stockholders for monetary damages for breach of his fiduciary duty as a
director to the extent allowed under the GCL.
 
     The Underwriting Agreement (Exhibit 1) provides for indemnification by the
Underwriter of the Company and its directors and officers, and by the Company of
the Underwriter for certain liabilities, including liabilities, arising under
the Securities Act of 1933, as amended.
 
     The above discussion of the Company's Certificate of Incorporation and
Bylaws, Section 145 of the Delaware Law and the Underwriting Agreement is not
intended to be exhaustive and is qualified in its entirety by each of such
documents and such statute.
 
     The Company has entered into indemnification agreements with its directors
and certain of its officers.

ITEM 17. UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act that is incorporated by reference in this Registration Statement
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
     The undersigned Registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities
     Act, the information omitted from the form of prospectus filed as part of
     this Registration Statement in reliance upon Rule 430A and contained in a
     form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     Registration Statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus shall
     be deemed to be a new Registration Statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

Dear Sirs:

         1.   Introductory.  Tesoro Petroleum Corporation, a Delaware
corporation ("Company"), proposes to issue and sell 5,350,000 shares ("Firm
Shares") of its Common Stock, par value $.16 2/3 per share ("Common Stock"), and
also proposes to issue and sell to the Underwriters, at your option, an
aggregate of not more than 500,000 additional shares ("Optional Shares") of its
Common Stock as set forth below.  The Firm Shares and the Optional Shares are
hereinafter collectively referred to as the "Securities".  The Company hereby
agrees with the several Underwriters named in Schedule A hereto
("Underwriters") as follows:

         2.   Representations and Warranties of the Company.  The Company
represents and warrants to, and agrees with, the several Underwriters that:

              (a)   The Company meets the requirements for use of Form S-3
   under the Securities Act of 1933, as amended ("Act"), and a registration
   statement (No. 33-53587), including a form of prospectus, relating to the
   Securities has been filed with the Securities and Exchange Commission
   ("Commission") and either (i) has been declared effective under the Act and
   is not proposed to be amended or (ii) is proposed to be amended by amendment
   or post-effective amendment.  If the Company does not propose to amend such
   registration statement and if any post-effective amendment to such
   registration statement has been filed with the Commission prior to the
   execution and delivery of this Agreement, the most recent such amendment has
   been declared effective by the Commission.  For purposes of this





                                      -1-
<PAGE>   2
   Agreement, "Effective Time" means (i) if the Company has advised you that it
   does not propose to amend such registration statement, the date and time as
   of which such registration statement, or the most recent post-effective
   amendment thereto (if any) filed prior to the execution and delivery of this
   Agreement, was declared effective by the Commission, or (ii) if the Company
   has advised you that it proposes to file an amendment or post-effective
   amendment to such registration statement, the date and time as of which such
   registration statement, as amended by such amendment or post-effective
   amendment, as the case may be, is declared effective by the Commission.
   "Effective Date" means the date of the Effective Time.  Such registration
   statement, as amended at the Effective Time, including all material
   incorporated by reference therein and including all information (if any)
   deemed to be a part of such registration statement as of the Effective Time
   pursuant to Rule 430A(b) under the Act, is hereinafter referred to as the
   "Registration Statement", and the form of prospectus relating to the
   Securities, as first filed with the Commission pursuant to and in accordance
   with Rule 424(b) ("Rule 424(b)") under the Act or (if no such filing is
   required) as included in the Registration Statement, including all material
   incorporated by reference in such prospectus, is hereinafter referred to as
   the "Prospectus".

              (b)   If the Effective Time is prior to the execution and
   delivery of this Agreement:  (i) on the Effective Date, the Registration
   Statement conformed in all respects to the requirements of the Act and the
   rules and regulations of the Commission ("Rules and Regulations") and did
   not include any untrue statement of a material fact or omit to state any
   material fact required to be stated therein or necessary to make the
   statements therein not misleading, and (ii) on the date of this Agreement,
   the Registration Statement conforms, and at the time of filing of the
   Prospectus pursuant to Rule 424(b), the Registration Statement and the
   Prospectus will conform, in all respects to the requirements of the Act and
   the Rules and Regulations, and neither of such documents includes, or will
   include, any untrue statement of a material fact or omits, or will omit, to
   state any material fact required to be stated therein or necessary to make
   the statements therein not misleading.  If the Effective Time is subsequent
   to the execution and delivery of this Agreement:  on the Effective Date, the
   Registration Statement and the Prospectus will conform in all respects to
   the requirements of the Act and the Rules and Regulations, and neither of
   such documents will include any untrue statement of a material fact or will
   omit to state any material fact required to be stated therein or necessary
   to make the statements therein not misleading.  The two preceding sentences
   do not apply to statements in or omissions from the Registration Statement
   or Prospectus based upon written information furnished to the Company by any
   Underwriter through you specifically for use therein.

              (c)  The documents which are incorporated by reference in the
   Registration Statement and the Prospectus, and any amendments or supplements
   thereto, when they were filed with the Commission or were or hereafter are
   last amended, complied or will comply in all respects with the requirements
   of the Securities Exchange Act of 1934, as amended ("Exchange Act"), and the
   Rules and Regulations promulgated under the Exchange Act, and when read
   together with the information in the Prospectus, no such document, when it
   was filed with the Commission or was or hereafter is last amended, contained
   or will contain an





                                      -2-

   untrue statement of a material fact or omitted to state a material fact
   required to be stated therein or necessary to make the statements therein
   not misleading.

              (d)   All the outstanding shares of capital stock of the Company
   have been, and the Securities, when issued, delivered and paid for in the
   manner herein discussed, will be, duly authorized, validly issued, fully
   paid and nonassessable and free of any preemptive or similar rights.  The
   capital stock of the Company conforms to the description thereof contained
   in the Registration Statement and the Prospectus.  Except as disclosed in
   the Prospectus, (i) there are no outstanding options, warrants or other
   rights to acquire any shares of the capital stock of the Company or
   securities convertible into or exercisable or exchangeable for any shares of
   the capital stock of the Company, and (ii) there are no restrictions upon
   the voting or transfer of any shares of the capital stock of the Company
   pursuant to the Company's certificate of incorporation or bylaws or any
   agreement or other instrument to which the Company is a party or by which it
   is bound.

              (e)   The Company is a corporation duly organized and validly
   existing in good standing under the laws of the State of Delaware, and is
   duly registered and qualified to conduct its business and is in good
   standing in each jurisdiction where the nature of its properties or the
   conduct of its business requires such registration or qualification, except
   where the failure so to register or qualify will not have a material adverse
   effect on the condition (financial or other), business, properties, net
   worth or results of operations of the Company and the Subsidiaries (as
   hereinafter defined) taken as a whole.

              (f)   All the Company's subsidiaries that are required to be
   listed in an exhibit to the Registration Statement or to any document
   incorporated by reference therein are so listed.  All of such subsidiaries,
   together with Tesoro E&P Company, L.P., a Delaware limited partnership, and
   Tesoro Gas Resources Company, Inc., a Delaware corporation, but excluding
   Tesoro Environmental Resources Company, a Delaware corporation, are referred
   to collectively herein as the "Subsidiaries".  Each Subsidiary is a
   corporation or limited partnership duly organized, validly existing and in
   good standing in the jurisdiction of its organization, and is duly
   registered and qualified to conduct its business and is in good standing in
   each jurisdiction where the nature of its properties or the conduct of its
   business requires such registration or qualification, except where the
   failure to so register or qualify will not have a material adverse effect on
   the condition (financial or other), business, properties, net worth or
   results of operations of the Company and the Subsidiaries, taken as a whole.
   All the outstanding shares of capital stock of, or other equity interests
   in, each of the Subsidiaries have been duly authorized and validly issued,
   are fully paid and nonassessable and are owned by the Company directly, or
   indirectly through one of the other Subsidiaries, free and clear of any
   lien, adverse claim, security interest, equity or other encumbrance, except

   material obligations with respect to such Permits, and no event has occurred
   that allows, or after notice or lapse of time, or both, would allow,
   revocation or termination thereof or result in any other material impairment

   therefor.  The property and business of the Company and the Subsidiaries,
   taken as a whole, conform in all material respects to the descriptions

   Company and the Subsidiaries, taken as a whole, or (iii) results or will
   result in the creation or imposition of any lien, charge or encumbrance upon

   the terms of any agreement or instrument to which any of them is a party or
   by which any of them may be bound or to which any of the property or assets
   of any of them is subject, which creation or imposition would have a

Underwriters, and the Underwriters agree, severally and not jointly, to
purchase from the Company, at a purchase price of $9.855 per share, the
respective numbers of Firm Shares set forth opposite the names of the
Underwriters in Schedule A hereto.

         The Company will deliver the Firm Shares to you for the accounts of
the Underwriters, against payment of the purchase price by certified or
official bank check or checks in federal

Botts, L.L.P., One Shell Plaza, Houston, Texas, at 10:00 A.M., Houston time, on
June 29, 1994 or at such other date and time not later than seven full business
days thereafter as you and the Company determine, such time being herein
referred to as the "First Closing Date".  At the First Closing Date, the
Company will reimburse you by certified or official bank check for the cost of
obtaining federal (same day) funds and for one day of interest, at the federal
(same day) funds interest rate, on the aggregate Firm Shares purchase price.

form, in such denominations and registered in such names as you request two
business days prior to the First Closing Date and will be made available for
checking and packaging at the office of CS First Boston Corporation at least 24

the number of Optional Shares specified in such notice and the Underwriters
agree, severally and not jointly, to purchase such Optional Shares.  Such
Optional Shares shall be purchased from the Company for the account of each
Underwriter in the same proportion as the number of Firm Shares set forth

of Firm Shares (subject to adjustment by you to eliminate fractions) and may be
purchased by the Underwriters only for the purpose of covering over-allotments
made in connection with the sale of the Firm Shares. No Optional Shares shall
be sold or delivered unless the Firm Shares previously have been, or
simultaneously are, sold and delivered.  The right to purchase the Optional
Shares or any portion thereof may be surrendered and terminated at any time
upon notice by you to the Company.

        The time for the delivery of and payment for the Optional Shares, being
herein referred to as an "Optional Shares Closing Date" (which may be the First
Closing Date), shall be determined by you but shall not be later than ten days
after written notice of election to purchase the Optional Shares is given. The
Company will deliver the OptionalShares to you for the accounts of the several
Underwriters, against payment of the purchase price therefor by certified or
official bank check or checks in federal (same day) funds drawn to the order
of the Company, at the office of CS First Boston Corporation.  At the Optional
Shares Closing Date, the Company will reimburse you by certified or official
bank check for the cost of obtaining federal (same day) funds and for one day
of interest, at the federal (same day) funds interest rate, on the Optional
Shares purchase price.  The certificates for the Optional Shares will be in
definitive form, in such denominations and registered in such names as you
request two business days prior to the Optional Shares Closing Date (except in
the event that the Optional Shares Closing Date is the First Closing Date, in
which event such request will be made at least 24 hours prior to the Optional
Shares Closing Date) and will be made available for checking and packaging at
the above office of CS First Boston Corporation at least 24 hours prior to the
Optional Shares Closing Date.

   necessary to make the statements therein, in the light of the circumstances
   under which they were made, not misleading, or if it is necessary at any
   time to amend the Prospectus to comply with the Act, the Company promptly
   will prepare and file with the Commission an amendment or supplement which
   will correct such statement or omission or an amendment which will effect

   related preliminary prospectus, the Prospectus and all amendments and
   supplements to such documents, in each case as soon as available and in such
   quantities as you reasonably request.

   qualification of the Securities for sale under the laws of such
   jurisdictions as you designate and to continue such qualifications in effect
   so long as required for the distribution, except that the Company will

   not be required in connection therewith to qualify as a foreign corporation
   or to execute a general consent to service of process in any jurisdiction.

by the Company of its obligations hereunder and to the following additional
conditions precedent:

              (a)   You shall have received a letter, dated the date of
   delivery thereof (which, if the Effective Time is prior to the execution and
   delivery of this Agreement, shall be on or prior to the date of this
   Agreement or, if the Effective Time is subsequent to the execution and
   delivery of this Agreement, shall be prior to the filing of the amendment or
   post-effective amendment to the registration statement to be filed shortly
   prior to the Effective Time), of Deloitte & Touche confirming that they are
   independent public accountants within the meaning of the Act and the
   applicable published Rules and Regulations thereunder and stating in effect
   that:

                    (i)    in their opinion the financial statements and
         schedules examined by them and included in the Registration Statement
         comply in form in all material respects with the applicable accounting
         requirements of the Act and the related published Rules and
         Regulations;

                    (ii)   they have made a review of the unaudited financial
         statements included in the Registration Statement in accordance with
         standards established by the American Institute of Certified Public
         Accountants, as indicated in their report attached to such letter;

                    (iii)  on the basis of the review referred to in clause
         (ii) above, a reading of the latest available interim financial
         statements of the Company, inquiries of officials of the Company who
         have responsibility for financial and accounting matters and other
         specified procedures, nothing came to their attention that caused them
         to believe that:

                    (A)    the unaudited financial statements included in the
              Registration Statement do not comply in form in all material
              respects with the applicable accounting requirements of the Act
              and the related published Rules and Regulations or are not in
              conformity with generally accepted accounting principles applied
              on a basis substantially consistent with that of the audited
              financial statements in the Registration Statement;

                    (B)    at the date of the latest available balance sheet
              read by such accountants, or at a subsequent specified date not
              more than five days prior to the date of this Agreement, there
              was any change in the capital stock or any increase in short-term
              or long-term debt of the Company and its consolidated
              subsidiaries or, at the date of the latest available balance
              sheet read by such accountants, there was any decrease in
              consolidated total current assets or common stock and other
              stockholders' equity, as compared with amounts shown on the
              latest balance sheet included in the Prospectus; or

                    (C) for the period from the closing date of the latest
              income statement included in the Prospectus to the closing date
              of the latest available income





                                      -13-
<PAGE>   14
              statement read by such accountants, there were any decreases, as
              compared with the corresponding period of the previous year and
              with the period of corresponding length ended the date of the
              latest income statement included in the Prospectus, in total
              consolidated revenues, operating income or in the total or per
              share amounts of net earnings before extraordinary items or of
              net earnings;

         except in all cases set forth in clauses (B) and (C) above for
         changes, increases or decreases which the Prospectus discloses have
         occurred or may occur;

                    (iv)   on the basis of a reading of the unaudited pro forma
         consolidated financial statements included in the Registration
         Statement and the Prospectus (the "pro forma financial statements"),
         inquiries of officials of the Company who have responsibility for
         financial and accounting matters, other specified procedures, and
         proving the arithmetic accuracy of the application of the pro forma
         adjustments to the historical amounts in the pro forma financial
         statements, nothing came to their attention which caused them to
         believe that the pro forma financial statements do not comply in form
         in all material respects with the applicable accounting requirements
         of Rule 11-02 of Regulation S-X or that the pro forma adjustments have
         not been properly applied to the historical amounts in the compilation
         of such statements; and

                    (v)    they have compared specified dollar amounts (or
         percentages derived from such dollar amounts) and other financial
         information contained in the Registration Statement (in each case to
         the extent that such dollar amounts, percentages and other financial
         information are derived from the general accounting records of the
         Company and its subsidiaries subject to the internal controls of the
         Company's accounting system or are derived directly from such records
         by analysis or computation) with the results obtained from inquiries,
         a reading of such general accounting records and other procedures
         specified in such letter and have found such dollar amounts,
         percentages and other financial information to be in agreement with
         such results.

         For purposes of this subsection, if the Effective Time is subsequent
         to the execution and delivery of this Agreement, "Registration
         Statement" shall mean the registration statement as proposed to be
         amended by the amendment or post-effective amendment to be filed
         shortly prior to the Effective Time, and "Prospectus" shall mean the
         prospectus included in the Registration Statement.   All financial
         statements and schedules included in material incorporated by
         reference into the Prospectus shall be deemed included in the
         Registration Statement for purposes of this subsection.

              (b)   You shall have received a letter, dated the date of
   delivery thereof (which, if the Effective Time is prior to the execution and
   delivery of this Agreement, shall be on or prior to the date of this
   Agreement or, if the Effective Time is subsequent to the execution and
   delivery of this Agreement, shall be prior to the filing of the amendment or
   post-effective amendment to the registration statement to be filed shortly
   prior to the Effective Time), of Netherland Sewell confirming that they are
   independent petroleum engineers

   within the meaning of the Act and the applicable published Rules and
   Regulations thereunder and to such further effect as you may reasonably
   request.

              (c)   If the Effective Time is not prior to the execution and
   delivery of this Agreement, the Effective Time shall have occurred not later
   than 10:00 P.M., New York time, on the date of this Agreement or such later
   date as shall have been consented to by you.  If the Effective Time is prior
   to the execution and delivery of this Agreement, the Prospectus shall have
   been filed with the Commission in accordance with the Rules and Regulations
   and Section 5(a) of this Agreement.  Prior to such Closing Date, no stop
   order suspending the effectiveness of the Registration Statement shall have
   been issued and no proceedings for that purpose shall have been instituted
   or, to the knowledge of the Company or you, shall be contemplated by the
   Commission.

              (d)   Subsequent to the execution and delivery of this Agreement,
   there shall not have occurred (i) any change, or any development involving a
   prospective change, in or affecting particularly the business or properties
   of the Company or any Subsidiary which, in the judgment of a majority in
   interest of the Underwriters including you, materially impairs the
   investment quality of the Securities; (ii) any downgrading in the rating of
   any debt securities of the Company by any "nationally recognized statistical
   rating organization" (as defined for purposes of Rule 436(g) under the Act),
   or any public announcement that any such organization has under surveillance
   or review its rating of any debt securities of the Company (other than an
   announcement with positive implications of a possible upgrading, and no
   implication of a possible downgrading, of such rating); (iii) any suspension
   or limitation of trading in securities generally on the New York Stock
   Exchange, or any setting of minimum prices for trading on such exchange, or
   any suspension of trading of any securities of the Company on any exchange
   or in the over-the-counter market; (iv) any banking moratorium declared by
   Federal or New York authorities; or (v) any outbreak or escalation of major
   hostilities in which the United States is involved, any declaration of war
   by Congress or any other substantial national or international calamity or
   emergency if, in the judgment of a majority in interest of the Underwriters
   including you, the effect of any such outbreak, escalation, declaration,
   calamity or emergency makes it impractical or inadvisable to proceed with
   completion of the sale of and payment for the Securities.

              (e)   You shall have received an opinion, dated such Closing
   Date, of Fulbright & Jaworski L.L.P., counsel for the Company, to the effect
   that:

                    (i)    The Company is a corporation duly incorporated and

         effect upon the Company and the Subsidiaries, taken as a whole; and
         all of the outstanding shares of capital stock of, or other equity
         securities in, each of the Subsidiaries have been duly authorized and
         validly issued, are fully paid and nonassessable, and are owned of
         record, and to the best knowledge of such counsel are beneficially

         amendments thereto, if any, have become effective under the Act and,
         to the best knowledge of such counsel, no stop order suspending the
         effectiveness of the Registration Statement has been issued and no

         statistical data contained or incorporated by reference therein and
         the exhibits thereto, as to which such counsel need not express any
         opinion) comply as to form in all material respects with the

         supplement thereto, incorporated by reference into the Registration
         Statement or the Prospectus (except for the financial statements and
         the notes thereto and the schedules and other financial, reserve and
         statistical data contained or incorporated by reference therein and
         the exhibits thereto, as to which such counsel need not express any

         Exchange Act;

                    (xi)   To the best knowledge of such counsel, (A) other
         than as described in the Registration Statement and the Prospectus,
         there are no legal or governmental proceedings pending or threatened
         against the Company or any of the Subsidiaries, or to which the

         properties is subject, that are required to be described in the
         Registration Statement or Prospectus and (B) there are no agreements,
         contracts, indentures, leases or other documents or instruments, that
         are required to be described in the Registration Statement or the

         not described as required;

                    (xiii)  The statements in the Registration Statement and
         Prospectus, insofar as they are descriptions of contracts, agreements
         or other legal documents to which the Company or any of the
         Subsidiaries is a party, are accurate in all material respects and
         present fairly the information required to be shown; and

                     (xiv)  Except as described in the Prospectus, such counsel
         knows of no outstanding option, warrant or other right calling for the

   for the Underwriters, representatives of the independent public accountants
   for the Company and your representatives at which the contents of the
   Registration Statement and the Prospectus and related matters were discussed
   and, although such counsel is not passing upon and does not assume any
   responsibility for the accuracy, completeness or fairness of the statements
   contained in the Registration Statement or the Prospectus (except to the
   extent specified elsewhere in this opinion letter), on the basis of the
   foregoing (relying as to materiality to a large extent upon the opinions of
   officers and other representatives of the Company), no facts have come to
   such counsel's attention that lead it to believe that the Registration
   Statement, at the Effective Time, contained an untrue statement of a
   material fact or omitted to state a material fact required to be stated
   therein or necessary to make the statements therein not misleading or that
   the Prospectus, as of the Effective Date, contained an untrue statement of a
   material fact oromitted to state a material fact necessary to make the
   statements therein, in the light of the circumstances under which they were
   made, not misleading (except as to financial statements, schedules or other
   financial or statistical data or the oil and gas reserve evaluation and
   related data included in the Registration Statement or the Prospectus, as to
   which such counsel express no opinion).

              In rendering such opinions, such counsel may (i) rely in respect
   of factual matters upon certificates of officers of the Company and upon
   information obtained from public officials and other sources believed by
   such counsel to be reliable, (ii) assume that the signatures on all
   documents examined by such counsel (other than the signature of the Company
   on this Agreement) are genuine, which assumption they may state they have
   not independently verified, (iii) state that their opinion is limited to
   federal laws, Texas law, New York law and the Delaware General Corporation
   Law, (iv) state that their opinion is furnished as counsel to the Company to
   you and is solely for your benefit and (v) include other customary
   conditions and exceptions in their opinion acceptable to you and your
   counsel.

              (f)   You shall have received from Baker & Botts, L.L.P., counsel
   for the Underwriters, such opinion or opinions, dated such Closing Date,
   with respect to the incorporation of the Company, the validity of the
   Securities, the Registration Statement, the Prospectus and other related
   matters as you may require, and the Company shall have furnished to such
   counsel such documents as they request for the purpose of enabling them to

              (g)   You shall have received a certificate, dated such Closing
   Date, of the President or any Vice-President and a principal financial or
   accounting officer of the Company in which such officers, to the best of
   their knowledge after reasonable investigation, shall state that the
   representations and warranties of the Company in this Agreement are true and
   correct, that the Company has complied with all agreements and satisfied all
   conditions on its part to be performed or satisfied hereunder at or prior to
   such Closing Date, that no stop order suspending the effectiveness of the
   Registration Statement has been issued and no proceedings for that purpose
   have been instituted or are contemplated by the Commission and that,

   position or results of operation of the Company and the Subsidiaries except
   as set





                                      -19-
<PAGE>   20
   forth in or contemplated by the Prospectus, excluding any material
   incorporated by reference into the Prospectus subsequent to the execution
   and delivery of this Agreement.

              (h)   You shall have received a letter, dated such Closing Date,
   of Deloitte & Touche which meets the requirements of subsection (a) of this
   Section, except that the specified date referred to in such subsection will
   be a date not more than five days prior to such Closing Date for the
   purposes of this subsection.

              (i)   You shall have received a letter, dated such Closing Date,
   of Netherland Sewell to such effect as you may reasonably request.

              (j)   The Securities shall have been duly listed, subject only to
   notice of issuance, on the New York Stock Exchange.

              (k)   You shall have received copies of the agreements between
   the Underwriters and each of the persons and entities listed on Schedule B
   hereto, which agreements (other than the agreement with MetLife Security
   Insurance Company of Louisiana ("MetLife Louisiana")) provide that for a
   period of 90 days (and in the case of Oakville N.V. 60 days) after the
   initial public offering of the Securities, the respective person will not,
   without the prior written consent of CS First Boston Corporation, directly
   or indirectly, sell, agree to sell, contract to sell or otherwise dispose of
   any shares of Common Stock or any shares of preferred stock, no par value
   ("Preferred Stock"), of the Company or any securities convertible into or
   exercisable for any such shares of Common Stock or Preferred Stock and which
   agreement with MetLife Louisiana is dated June 1, 1994 and executed for
   MetLife Louisiana by James S. Russell, Vice President and Treasurer of
   MetLife Louisiana.

The Company will furnish you with such conformed copies of such opinions,
certificates, letters and documents as you reasonably request.

         7.   Indemnification and Contribution.  (a) The Company will indemnify
and hold harmless each Underwriter against any losses, claims, damages or
liabilities, joint or several, to which such Underwriter may become subject,
under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
the Registration Statement, the Prospectus, or any amendment or supplement
thereto, or any related preliminary prospectus, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not
misleading, and will reimburse each Underwriter for any legal or other expenses
reasonably incurred by such Underwriter in connection with investigating or
defending any such loss, claim, damage, liability or action as such expenses
are incurred; provided, however, that the Company will not be liable in any
such case to the extent that any such loss, claim, damage or liability arises
out of or is based upon an untrue statement or alleged untrue statement in or
omission or alleged omission from any of such documents in reliance upon and in
conformity with written information furnished to the Company by any Underwriter
through you specifically for use therein; and provided, further, that with
respect to any untrue statement





                                      -20-
<PAGE>   21
or omission or alleged untrue statement or omission made in any preliminary
prospectus the indemnity agreement contained in this subsection (a) shall not
inure to the benefit of any Underwriter (or any person who controls such
Underwriter) from whom the person asserting any such losses, claims, damages or
liabilities purchased the Securities concerned, to the extent that any such
loss, claim, damage or liability of such Underwriter results from the fact that
there was not sent or given to such person a copy of the Prospectus (exclusive
of material incorporated by reference) or the Prospectus as amended or
supplemented (exclusive of material incorporated by reference), at or prior to
the written confirmation of the sale of such Securities to such person in any
case where such delivery is required by the Act and the untrue statement or
omission or alleged untrue statement or omission of a material fact made in such
preliminary prospectus was corrected in the Prospectus (or the Prospectus as
amended or supplemented) and where the Company had previously furnished copies
thereof to such Underwriter.

         (b)  Each Underwriter, severally and not jointly, will indemnify and
hold harmless the Company against any losses, claims, damages or liabilities to
which the Company may become subject, under the Act or otherwise, insofar as
such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon any untrue statement or alleged untrue statement
of any material fact contained in the Registration Statement, the Prospectus,
or any amendment or supplement thereto, or any related preliminary prospectus,
or arise out of or are based upon the omission or the alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, in each case to the extent, but only to the
extent, that such untrue statement or alleged untrue statement or omission or
alleged omission was made in reliance upon and in conformity with written
information furnished to the Company by such Underwriter through you
specifically for use therein, and will reimburse any legal or other expenses
reasonably incurred by the Company in connection with investigating or
defending any such loss, claim, damage, liability or action as such expenses
are incurred.

         (c)  Promptly after receipt by an indemnified party under this Section
of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under
subsection (a) or (b) above, notify the indemnifying party of the commencement
thereof; but the omission so to notify the indemnifying party will not relieve
it from any liability which it may have to any indemnified party otherwise than
under subsection (a) or (b) above.  In case any such action is brought against
any indemnified party and it notifies the indemnifying party of the
commencement thereof, the indemnifying party will be entitled to participate
therein and, to the extent that it may wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel satisfactory to such indemnified party (who shall not, except with the
consent of the indemnified party, be counsel to the indemnifying party), and
after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party will not be
liable to such indemnified party under this Section for any legal or other
expenses subsequently incurred by such indemnified party in connection with the
defense thereof other than reasonable costs of investigation. No indemnifying
party shall, without the prior written consent of the indemnified party, effect
any settlement of any





                                      -21-
<PAGE>   22
pending or threatened action in respect of which any indemnified party is or
could have been a party and indemnity could have been sought hereunder by such
indemnified party unless such settlement includes an unconditional release of
such indemnified party from all liability on any claims that are the subject
matter of such action.

         (d)  If the indemnification provided for in this Section is
unavailable or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above, then each indemnifying party shall contribute to
the amount paid or payable by such indemnified party as a result of the losses,
claims, damages or liabilities referred to in subsection (a) or (b)above (i) in
such proportion as is appropriate to reflect the relative benefits received by
the Company on the one hand and the Underwriters on the other from the offering
of the Securities or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits referred to in clause (i) above but also the
relative fault of the Company on the one hand and the Underwriters on the other
in connection with the statements or omissions which resulted in such losses,
claims, damages or liabilities as well as any other relevant equitable
considerations.  The relative benefits received by the Company on the one hand
and the Underwriters on the other shall be deemed to be in the same proportion
as the total net proceeds from the offering (before deducting expenses)
received by the Company bear to the total underwriting discounts and
commissions received by the Underwriters.  The relative fault shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to
state a material fact relates to information supplied by the Company or the
Underwriters and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such untrue statement or omission.  The
amount paid by an indemnified party as a result of the losses, claims, damages
or liabilities referred to in the first sentence of this subsection (d) shall
be deemed to include any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any action or
claim which is the subject of this subsection (d).  Notwithstanding the
provisions of this subsection (d), no Underwriter shall be required to
contribute any amount in excess of the amount by which the total price at which
the Securities underwritten by it and distributed to the public were offered to
the public exceeds the amount of any damages which such Underwriter has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission.  No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation.  The Underwriters' obligations in this subsection (d) to
contribute are several in proportion to their respective underwriting
obligations and not joint.

         (e)  The obligations of the Company under this Section shall be in
addition to any liability which the Company may otherwise have and shall
extend, upon the same terms and conditions, to each person, if any, who
controls any Underwriter within the meaning of the Act; and the obligations of
the Underwriters under this Section shall be in addition to any liability which
the respective Underwriters may otherwise have and shall extend, upon the same
terms and conditions, to each director of the Company, to each officer of the
Company who





                                      -22-
<PAGE>   23
has signed the Registration Statement and to each person, if any, who controls
the Company within the meaning of the Act.

         8.   Default of Underwriters.  If any Underwriter or Underwriters
default in their obligations to purchase Securities hereunder on either the
First or Optional Shares Closing Date and the aggregate number of Securities
that such defaulting Underwriter or Underwriters agreed but failed to purchase
does not exceed 10% of the total number of Securities that the Underwriters are
obligated to purchase on such Closing Date, you may make arrangements
satisfactory to the Company for the purchase of such Securities by
otherpersons, including any of the Underwriters, but if no such arrangements
are made by such Closing Date, the non-defaulting Underwriters shall be
obligated severally, in proportion to their respective commitments hereunder,
to purchase the Securities that such defaulting Underwriters agreed but failed
to purchase on such Closing Date.  If any Underwriter or Underwriters so
default and the aggregate number of Securities with respect to which such
default or defaults occur exceeds 10% of the total number of Securities that
the Underwriters are obligated to purchase on such Closing Date, and
arrangements satisfactory to you and the Company for the purchase of such
Securities by other persons are not made within 36 hours after such default,
this Agreement will terminate without liability on the part of any
non-defaulting Underwriter or the Company, except as provided in Section 9
(provided that if such default occurs with respect to Optional Shares after the
First Closing Date, this Agreement will not terminate as to the Firm Shares).
As used in this Agreement, the term "Underwriter" includes any person
substituted for an Underwriter under this Section.  Nothing herein will relieve
a defaulting Underwriter from liability for its default.

         9.   Survival of Certain Representations and Obligations.  The
respective indemnities, agreements, representations, warranties and other
statements of the Company or its officers and of the several Underwriters set
forth in or made pursuant to this Agreement will remain in full force and
effect, regardless of any investigation, or statement as to the results
thereof, made by or on behalf of any Underwriter, the Company or any of their
respective representatives, officers or directors or any controlling person,
and will survive delivery of and payment for the Securities.  If this Agreement
is terminated pursuant to Section 8 or if for any reason the purchase of the
Securities by the Underwriters is not consummated, the Company shall remain
responsible for the expenses to be paid or reimbursed by it pursuant to Section
5 and the respective obligations of the Company and the Underwriters pursuant
to Section 7 shall remain in effect, and if any Securities have been purchased
hereunder the representations and warranties in Section 2 and all obligations
under Section 5 shall also remain in effect.  If the purchase of the Securities
by the Underwriters is not consummated for any reason other than solely because
of the termination of this Agreement pursuant to Section 8 or the occurrence of
any event specified in clause (iii), (iv) or (v) of Section 6(d), the Company
will reimburse the Underwriters for all out-of-pocket expenses (including fees
and disbursements of counsel) reasonably incurred by them in connection with
the offering of the Securities.

         10.  Notices.  All communications hereunder will be in writing and, if
sent to the Underwriters, will be mailed, delivered or telegraphed and
confirmed to you c/o CS First Boston Corporation, Park Avenue Plaza, New York,

Underwriter.

         11.  Successors.  This Agreement will inure to the benefit of and be
binding upon the parties hereto and their respective successors and the
officers and directors and controlling persons referred to in Section 7, and no
other person will have any right or obligation hereunder.

         12.  Representation of Underwriters.  You will act for the several
Underwriters in connection with this financing, and any action under this
Agreement taken by you jointly or by CS First Boston Corporation will be
binding upon all the Underwriters.

         13.  Counterparts.  This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all such
counterparts shall together constitute one and the same Agreement.

         14.  Applicable Law.  This Agreement shall be governed by, and
construed in accordance with, the laws of the State of New York.

agreement, kindly sign and return to us one of the counterparts hereof,

                                        TESORO PETROLEUM CORPORATION

interest thereon to be immediately due and payable.  Upon any such declaration
having been made, the Note and all other amounts owing hereunder and under the
Loan Documents shall become immediately due and payable without presentment,
demand, protest or other notice of any kind, all of which are hereby expressly
waived by the Borrower and the Guarantor.  The obligations, from and after the

taking recourse to its rights under the Security Documents, and either before or
after a judicial foreclosure of the deed of trust encumbering the Real Property
under AS 09.45.170-220.

                               GUARANTY AGREEMENT

        THIS GUARANTY AGREEMENT ("Guaranty") made as of the 26th day of May,
1994 to NATIONAL BANK OF ALASKA, a National Banking Association ("Bank") by
TESORO PETROLEUM CORPORATION ("Guarantor"), under the Loan Agreement dated as
of May 26, 1994 (the "Agreement"), between TESORO ALASKA PETROLEUM COMPANY, a
Delaware corporation ("Borrower"), Guarantor and the Bank.

                              W I T N E S S E T H

        WHEREAS, the Bank intends to make a Loan to the Borrower in the maximum
amount of FIFTEEN MILLION AND NO/100 DOLLARS ($15,000,000), under and pursuant
to the Agreement; and

        WHEREAS, the Guarantor is desirous that the Bank make the Loan and are
willing to enter into this Guaranty as an inducement to the Bank to make the
Loan as evidenced by the Note.

        NOW THEREFORE, for good and valuable consideration as an inducement to
the Bank to make the Loan, the Guarantor does hereby, subject to the terms
hereof, covenant and agree with the Bank as follows:


                                   ARTICLE I
                REPRESENTATIONS AND WARRANTIES OF THE GUARANTOR

        SECTION 1.1.  The Guarantor represents and warrants that execution and
delivery of this Guaranty will not result in a  breach of any material
indenture, commitment, agreement or other instrument to which it is a party or
by which it is bound or violate in any material respect any existing law,
administrative regulation or any court order or consent decree to which it is
subject; and that this Guaranty constitutes a legal, valid and binding
obligation of the Guarantor in accordance with its terms.

        SECTION 1.2.  The Bank makes no representation or warranty, and assumes
no responsibility, with respect to the legality, sufficiency, enforceability,
validity, or collectibility of the Note.  The Guarantor represents and warrants
that the Guarantor has, independently and without reliance upon the Bank, and
based upon such documents and information as the Guarantor has deemed
appropriate, made the Guarantor's own decision to enter into this Guaranty.


                                   ARTICLE II
                            COVENANTS AND AGREEMENT

        SECTION 2.1.  The Guarantor hereby unconditionally guarantees
jointly and severally (with the other guarantors under





                                     -1-
<PAGE>   2
the Agreement, if any) to the Bank at all times: (a) the full and prompt
payment of an amount equal to the  total outstanding amounts due under the Loan
Documents when and as the same shall become due pursuant to the Loan Document
whether at the stated maturity thereof, by acceleration or otherwise; (b) the
full and prompt payment of all interest, costs and expenses due under the Note
or the other Loan Documents when and as the same shall become due and (c) all
indemnities, including, without limitation, environmental indemnities.  (The
foregoing, together with costs Bank may incur in enforcing this Guaranty, all
the "Obligations.") The Guarantor is liable for the full accelerated amount of
the Obligations, not solely to make each payment as and when the payment would
otherwise have become due.  In each and every case, the Guarantor agrees, in
the event of the failure of  Borrower to make payments of such principal or
interest, cost and expenses on the Loan, to make, or cause to be made such
payments to Bank.  All such payments shall be paid to Bank in lawful money of
the United States of America.  Each and every default in payment of the
principal and interest on the Loan shall give rise to a separate cause of
action hereunder, and separate suit may be brought hereunder as each cause of
action arises.  If suit is instituted to enforce this Guaranty, or if Bank
incurs attorneys' fees in its enforcement of the Loan Documents or of this
Guaranty, even if no suit is filed, the Guarantor agrees to pay Bank its costs
and attorneys' fees.

        SECTION 2.2.  The Guarantor's obligations under this Guaranty shall
be continuing, absolute and unconditional, and shall remain in full force and
effect until the  Obligations shall have been paid.   Without limiting the
foregoing, such obligations shall not be affected, modified, released,
discharged or impaired upon the happening from time to time of any of the
following events, whether or not such event shall occur with notice to or
consent of the Guarantor:

                (a)  the failure to give notice to the Guarantor of the
        occurrence of any event of default under the terms and provisions of
        this Guaranty or the other Loan Documents;

                 (b)  the transfer, assignment or mortgaging or the
        purported transfer, assignment or mortgaging of all or any part of the
        interest in the Borrower's collateral for the Loan;

                (c)  the waiver, surrender, compromise, settlement, release or
        termination by the Bank, as applicable, of the payment, performance or
        observance by the Borrower or the Guarantor of any of the obligations,
        covenants or agreements of any of them contained in the Loan Documents,
        this Guaranty, or any other guaranty now existing or hereafter
        obtained;





                                     -2-
<PAGE>   3
                (d)  the making, changing, altering, canceling, renewal,
        decrease, increase, or the extension of the time for payment of any
        principal of or premium, if any, or interest of any other obligation,
        covenant or agreement under or arising out of the Loan Documents or the
        extension or the renewal thereof;

                (e)  the taking or the omission of any of the actions permitted
        by the Loan Documents or this Guaranty;

                (f)  any failure, omission or delay on the part of Bank to
        enforce, assert or exercise any right, power or remedy conferred on
        Bank under the Loan Documents or in this Guaranty;

                (g)  the voluntary or involuntary liquidation, dissolution,
        sale or other disposition of all or substantially all the assets,
        marshalling of assets and liabilities, receivership, insolvency,
        bankruptcy, assignment for the benefit of creditors, reorganizations,
        arrangement, composition with creditors or readjustment of, or other
        similar proceedings affecting the Borrower, or any of its assets, or
        any allegation or contest of the validity or enforceability of the
        Note, or the Loan Documents;

                (h)  the surrender, release, exchange, substitution, dealing
        with or taking any additional collateral;

                (i)  the abstaining from taking advantage of or realizing upon
        any security interest or other guaranty;

                (j)  any impairment of collateral including, but not limited
        to, failure to perfect a security interest in the collateral. The Bank
        shall have no responsibility whatsoever with respect to any such
        collateral and shall not be obligated to insure, protect or preserve
        its value in any manner, or to attempt to realize any recovery from the
        collateral;

                (k)  to the extent permitted by law, any event or action taken
        that would, in the absence of this clause, result in the release or
        discharge of the Guarantor from the performance or observance of any
        obligation, covenant or agreement contained in this Guaranty or by
        operation of law; or

                (l)  the invalidity or unenforceability of the Loan Documents
        or any part thereof.

        SECTION 2.3.  For that portion of the Loan participated to other
lenders, no set off, counterclaim, reduction or diminution of an obligation, or
any defense of any kind or nature (other than by the Guarantor's performance of
its obligations hereunder to the





                                     -3-
<PAGE>   4
extent of such performance) which the Guarantor has or may come to have against
the Bank shall be available hereunder.

        SECTION 2.4.  The Bank shall notify Guarantor of any incipient Event of
Default if it has given Borrower notice of such incipient Event of Default. 
Upon the occurrence of any Event of Default, as such term is defined in the
Agreement, Bank may, in its sole discretion, without prior notice, have the
right to proceed first and directly against the Guarantor under this Guaranty
without proceeding against or exhausting any other remedies which it may have
and without resorting to any other guarantor or security held by Bank.

        SECTION 2.5.  Any financial accommodation granted or continued by the
Bank to the Borrower shall be conclusively deemed to have been induced hereby
and in reliance hereon.  The Guarantor hereby expressly waives notice from the
Bank of its acceptance and reliance on this Guaranty, and expressly waives
notice of all demands, presentments, and notices of every kind or nature,
including those of any action or non-action by the Borrower, Bank, the
Guarantor, any other guarantor, any of Borrower's creditors, or any other
person.  The non-prevailing party agrees to pay all costs, expenses and fees,
including all reasonable attorney's fees, which may be incurred by the
prevailing party in enforcing or attempting to enforce this Guaranty following
any default hereunder, whether the same shall be enforced by suit or otherwise,
or defending against such enforcement or attempted enforcement.

        SECTION 2.6.  This Guaranty is entered into by the Guarantor for the
benefit of the Bank and any successor(s) thereto, each of whom shall be
entitled to enforce performance and observance of this Guaranty to the same
extent as if it/they were parties signatory hereto.

        SECTION 2.7.  This Guaranty shall terminate with respect to the Loan
and the Guarantor shall have no further liability hereunder with respect to the
Loan from and after the time the liability of  Borrower thereon is terminated
and discharged and the Loan are paid.  The Obligations of the Guarantor shall
be reinstated to the extent that Bank is required to return any amounts
received in respect of or for the account of Borrower in any bankruptcy or
otherwise.

provision contained in this Guaranty and such breach is duly waived by the

period for which such interest is payable.  Interest on the principal balance
is due and payable in arrears beginning July 1, 1994, and thereafter as
provided in the Agreement.  Principal plus accrued interest on the Note is due
in full on January 1, 2002.

All payments on this Note shall be paid to the Bank as provided in the
Agreement at Section 2.  The principal balance and interest due hereon shall be
evidenced by Bank's records for the computation of principal and interest
balances owed by Borrower to Bank.

earned fully and will not be subject to refund upon early payment (whether
voluntary or as a result of default), except as otherwise required by law.
Except for the foregoing,

than it is due, except that after conversion, certain prepayment penalties as
set forth in the Agreement apply.

If this Note has not been paid in full when due,  Borrower agrees to pay all
costs and expenses of collection, including the reasonable attorneys' fees
incurred by the Bank.  If the Bank declares an Event of Default under the

without losing them.  Borrower and any other person who signs, guarantees or
endorses this Note, to the extent allowed by law, waive presentment, demand for
payment, protest and notice of dishonor.  Upon any change in the terms of this
Note, and unless otherwise expressly stated in writing by the holder of this
Note, no party who signs this Note, whether as maker, guarantor, accommodation
maker or endorser shall be released from liability.  All such parties agree
that the Bank may renew, extend (repeatedly and for any length of time) or
modify the Loans, or release any party or guarantor, and take any other action
deemed necessary by Bank without the consent of or notice to anyone except as
otherwise provided herein.

        AGREEMENT ("Agreement") made this 26th day of May, 1994, between TESORO
ALASKA PETROLEUM COMPANY, a Delaware corporation ("Borrower"), and NATIONAL
BANK OF ALASKA ("Bank"). Borrower is the owner of the real property described
on Exhibit C to a Loan Agreement between Borrower and the Bank dated this date
("Loan Agreement").


        Borrower proposes to construct upon the Property in accordance with the
plans and specifications more particularly identified in Exhibit "A" attached
hereto and incorporated herein by reference as may be amended from time to time
with the consent of Bank ("Plans"), the construction contract with Litwin
Engineers & Constructors, Inc. ("Contractor"), a copy of which has been
provided to the Bank ("Construction Contract") and a budget prepared by
Borrower attached to the Construction Contract ("Construction Budget").

        Borrower wishes to borrow from the Bank, and the Bank desires to loan
to Borrower, a sum not to exceed $15,000,000 pursuant to the Loan Agreement to
be used by Borrower for the purpose of constructing the Vacuum Unit.

        Terms not defined herein have the same meaning as defined in the Loan
Agreement.

        The Loans are further evidenced by the Note and Security Agreements
including a Deed of Trust ("Deed of Trust"), which Deed of Trust, subject to
liens permitted in the Loan Agreement, is to be a first lien upon the Property.

        As further consideration for making the Loans, Borrower and the Bank
desires to enter into various covenants to assure completion of the Vacuum Unit
in accordance with the Plans.

        NOW, THEREFORE, in consideration of the mutual covenants and promises
of the parties, and in further consideration for the making of the Loan, the
parties hereto




                                    PAGE 1
<PAGE>   5
agree as follows:


                                   ARTICLE I

                  CONSTRUCTION AND COMPLETION OF IMPROVEMENTS

1.1. CONSTRUCTION.

        Borrower shall diligently proceed with construction and completion of
the Vacuum Unit in accordance with the Plans. The Vacuum Unit shall be
completed on or before March 31, 1995, unless Bank consents in writing to
extend such completion date. Borrower shall timely record a Notice of
Completion as contemplated by A.S. 34.35.071, and five (5) days before such
recordation, give notice to all claimants entitled to notice under A.S. 34.
35.071.

1.2. CHANGES IN PLANS.

        There shall be no changes, modifications or field change orders in the
Construction Contract, Construction Budget and Plans without the prior written
consent of Bank, provided, however, changes, modifications or field change
orders that do not (i) increase the cost of the project by more than $500,000
for any one change, modification or field change order, or (ii) result in the
aggregate of such changes, modifications and field change orders costing in
excess of $2,500,000 excluding any amounts designated in the Construction
Budget as a contingency may be effected or made by Borrower without the prior
written consent of Bank. Regardless of the cost involved, Borrower shall
promptly provide a change order log or copies of each change order to Bank upon
request.  A change order must identify all parties involved in the change order
and define the responsibilities of each.

1.3. LISTS OF CONTRACTORS.

        Borrower shall cause the Contractor to furnish to Bank from time to
time, at Bank's request, after the execution of this Agreement, copies of all
unpriced purchase orders for materials, supplies and engineered equipment.  In
addition, Borrower will supply, at Bank's request, names of subcontractors,
including their respective addresses and telephone numbers. Included with the
list of the  subcontractors will be a general statement of the nature of the
work to be done, the labor and materials to be supplied, the names of the
materials vendors if known, the approximate




                                    PAGE 2
<PAGE>   6
dollar value of all such anticipated expenditures.  Bank shall have the right
to make direct contact with each subcontractor and materialmen to verify the
facts disclosed by said contract and correspondence or for any other purpose.
For work completed on the project, Borrower shall obtain lien waivers for
payments made to date (the form of which is attached hereto as Exhibit "B").

1.4. PURCHASE OF MATERIALS UNDER SECURITY AGREEMENTS.

        No materials, fixtures or any other part of the improvements shall be
purchased or installed under security agreements or other arrangements wherein
the seller reserves or purports to reserve the right to remove or to repossess
any such items or to consider them personal property after their incorporation
in the work of construction, unless authorized by Bank in writing.

1.5. COMPLIANCE WITH APPLICABLE LAWS.

        All work in connection with construction of the Vacuum Unit shall be
performed in compliance with all applicable laws, ordinances, rules and
regulations of federal, state, borough or municipal governments or agencies now
in force or that may be enacted hereafter, and in compliance with all
directions, rules and regulations of the fire marshall, health officer,
building inspector or other proper officers of any governmental agency now
having or hereafter acquiring jurisdiction.

1.6. INSPECTION.

        The Bank, through its officers, agents or employees, shall have the
right at all reasonable times:

                (a) to enter upon the Property, and inspect the Vacuum Unit and
        the work of construction to determine that the same is in conformity
        with the Plans and all of the requirements hereof; and

                (b) to examine the books, records, accounting data and other
        documents of Borrower pertaining to construction of the improvements
        and to make extracts therefrom or copies thereof. Said books, records
        and documents shall be made available to the Bank, its officers, agents
        or employees promptly upon written demand therefor.

        It is expressly understood and agreed, however, that the Bank is under
no duty to supervise the work of




                                    PAGE 3
<PAGE>   7

construction or inspect the work in process or Borrower's books and that any
such inspection is for the sole purpose of preserving Bank's rights hereunder.
No such inspection on the part of the Bank shall constitute a representation
that there has been or will be compliance with the Plans or that the
construction is free from defective materials or workmanship.

1.7. PROTECTION AGAINST LIEN CLAIMS.

        Borrower agrees to fully pay and discharge all claims for labor done,
materials and services furnished in connection with the construction of the
Vacuum Unit excepting such as Bank and Borrower may agree should be resisted.

1.8. WORKERS' COMPENSATION INSURANCE: OTHER.

        Borrower shall itself provide the insurance required by the Loan
Agreement and will cause to be provided by the Contractor all builders' risk,
workers' compensation, public liability, hazard, and other insurance coverages
required by (a) applicable law; (b) contemplated under the Construction
Contract  or (c) reasonably required by Bank.


                                  ARTICLE II
                                
                                LOAN ADVANCES

Representation of Borrower



        Borrower represents that the total of the funds to be advanced
hereunder is sufficient to pay the charges and expenses in connection with the
Loans and, together with funds provided by Borrower, all of the costs of
completing the Vacuum Unit in accordance with the Plans.

2.2. ADVANCES

        Advances shall be disbursed in the following manner except as expressly
herein provided:

                (a) Such sums to Bank at such time after execution hereof as
        the Bank may determine are necessary to pay:  Bank fees on each
        Advance, title insurance premiums, recording charges, other customary
        loan closing disbursements and Bank's costs as provided in Section 5.8
        herein.




                                    PAGE 4

<PAGE>   8
                        (b) As construction progresses, but not more frequently
        than monthly, such sums as are due to the Contractor, from Borrower for
        construction of the improvements. The periodic contract sum(s) due
        under the  Construction Contract shall be determined by Borrower as
        evidenced by a certificate(s) furnished to Bank.

                        (c) The balance thereof upon Borrower's Request for
        Advances pursuant to Section 2.4 hereunder for costs of the Vacuum Unit
        incurred by Borrower.


2.3. REVIEW OF DOCUMENTS.

        The only consideration passing from the Bank to Borrower is the Loan
proceeds.  The Bank is not the pay-out agent of Borrower.

        Any review or checking of the Plans, requisitions, invoices,
architects' certificates, lien waivers, and the like, in the course of
disbursing an Advance is solely for Bank's protection and Borrower has no
rights to rely on any procedures required or followed by the Bank.


2.4. REQUESTS FOR ADVANCES.

        To request an Advance, the Borrower shall furnish a statement ("Request
for Advance") setting forth the amount sought in such form and manner as Bank
may request, including, but not limited to, a trade payment breakdown and an
affirmation that all representations herein remain true and correct as of the
date thereof, and unless Bank is notified to the contrary prior to disbursement
of the requested Advance, will be so on the date thereof. The form for
Borrower's Request for Advances is attached hereto as Exhibit C.  All Requests
for Advances shall be filed with the Bank on or before March 31, 1995.

        the Deed of Trust is in a first lien position except as provided in
        subsection (i) herein.

                (q) The Advance is in accord with the Construction Budget.

                (r) Borrower shall have complied with, satisfied and fulfilled
        each and every term and condition of this Agreement and the Loan
        Documents including but not limited to Section 4 of the Loan Agreement
        and all endorsements thereto, to the date any Advance is to be made.

                (s) Each request with respect to each Advance shall constitute
        a representation and warranty by Borrower and the Guarantor that the
        conditions contained in this Section 3.2 have been satisfied.

3.3. APPLICATION OF ADVANCE.

        Bank may require Borrower to take such steps as Bank deems necessary to
require proper application of Advances; however, Bank shall have no obligation
to see to the proper application of such Advances by Borrower.  Advances may be
paid to Borrower or order or, at the option of Bank, to the Contractor,
materialmen, laborers, or subcontractors engaged in the construction project. 
The Bank may, at its option, pay amounts due and secured by existing mortgages,
deeds of trust and other encumbrances, the cost of clearing title to the
Collateral, assessments and taxes but only if delinquent, liens or claims of
liens against the Collateral, judgments entered against the Borrower, and any
other sums, but only if





                                    PAGE 8
<PAGE>   12
such payment is necessary to place and maintain Bank's security in a first lien
position.


3.4.  FINAL ADVANCE.

        In addition to all other conditions to Bank's obligation to make
Advances, Bank shall not be obligated to make the final Advance until Bank, in
its sole and reasonable judgment, is satisfied that the Vacuum Unit has been
completed in a good and workerlike manner in accordance with the Plans approved
by Bank and, without limiting the generality of the foregoing, Borrower has
furnished in form satisfactory to Bank:

                (a) a survey by a registered land surveyor showing the location
        of the improvements on the Property in accordance with the Plans, and
        showing the boundaries of the Property to be free of encroachments;

                (b) such permits of occupancy and operation and final
        inspections as may be required by public authorities having
        jurisdiction;

                (c) a detailed list of the fixtures and furnishings installed
        or to be installed in or used in connection with the Vacuum Unit, which
        shall in all respects be satisfactory to Bank, together with evidence
        satisfactory to Bank that the same have been paid for; and

                (d) all lien releases, canceled checks and evidence of payment
        which are required by this or any other agreement.

                (e) an engineer's certificate that the Vacuum Unit has been
        completed in accordance with the Plans.

                (f) title endorsement showing the Property free and clear of
        all liens and encumbrances except the Deed of Trust to the Bank, as
        satisfactory to Bank and as permitted by the Loan Agreement.

                              DEFAULT AND REMEDIES


4.1. EVENTS OF DEFAULT.

        The following events shall constitute Events of Default hereunder:

                (a) Substantial deviation in the work of construction from the
        Plans without the prior written approval of Bank or the appearance of
        defective workmanship or materials, which said deviation or defects are
        not corrected within thirty (30) days after written notice thereof to
        Borrower.

                (b) Cessation of the work of construction prior to completion
        of the Vacuum Unit for a continuous period of thirty (30) days or more
        unless such cessation is due to causes beyond the control of Borrower;

                (c) The breach of any covenant, warranty, promise, or
        representation constituting an Event of Default herein contained or in
        any other Loan Document, and the continuance of any such breach for a
        period of thirty (30) days after written notice thereof to Borrower,
        provided, however, that if a different period or notice requirement is
        specified for any particular breach under any other subsection of this
        Agreement, the specific provision shall control.


4.2. STOPPAGE OF CONSTRUCTION BY BANK.

        Where substantial deviations from the Plans appear, or defective or
unworkerlike labor or materials are being used in construction of the Vacuum
Unit, based on its judgment, Bank shall have the right, after written notice to
Borrower, to order stoppage of construction and demand that the deviations or
defective work be corrected.  After issuance of such an order in writing, no
further work shall be done on said Vacuum Unit or that portion which is the
subject of the stop order, without the prior written consent of Bank, unless
and until said deviations or defects have been fully corrected.



                                   PAGE 10
<PAGE>   14

4.3. REMEDIES OF BANK CUMULATIVE.

        All remedies of the Bank provided for herein are cumulative and shall
be in addition to any and all other rights and remedies provided by law,
including the Bank's lien and right of offset. The exercise of any right or
remedy by Bank hereunder shall not in any way constitute a cure or waiver of
default hereunder or under the Loan Documents or invalidate any act done
pursuant to any notice of default, or prejudice Bank in the exercise of any of
its rights hereunder or under the Loan Documents unless, in the exercise of
said rights, Bank realizes all amounts owed to it under the Loan Documents and
the provisions of this Agreement.

4.4. RIGHT TO CONTEST

        Notwithstanding anything to the contrary herein contained, Borrower
shall have the right to contest in good faith any claim, demand, levy or
assessment the assertion of which would constitute an Event of Default
hereunder.  Any such contest shall be prosecuted diligently and in a manner
unprejudicial to the Bank or the rights of the Bank hereunder. Upon demand by
Bank, Borrower shall make suitable provision by deposit of funds or by bond
satisfactory to Bank for the possibility that the contest will be unsuccessful.
Such provision shall be made within fifteen (15) days after demand therefor
and, if made by deposit of funds, the amount so deposited shall be disbursed in
accordance with the resolution of the contest either to Borrower or the adverse
claimant. Pending the outcome of the contest, the contested claim shall not
serve to constitute an Event of Default hereunder so long as the effect of such
claim as a lien upon the Property, the Vacuum Unit, or any part thereof, may
be or is being held in abeyance pending the outcome of such contest.



                                   ARTICLE V


                                 MISCELLANEOUS


5.1. NO WAIVER.

        No waiver of any default or breach by Borrower hereunder shall be
implied from any omission by Bank or the Bank to take action on account of such
default, if such default persists or is repeated; and no express waiver shall




                                   PAGE 11
<PAGE>   15
affect any default other than the default in the waiver, and it shall be
operative only for the time and to the extent therein stated. A waiver of any
covenant, term or condition contained herein shall not be construed as a waiver
of any subsequent breach of the same covenant, term or condition. The consent
or approval by the Bank to or of any act by Borrower requiring further consent
or approval shall not be deemed to waive or render unnecessary the consent or
approval to or of any subsequent similar act.

5.2. NO THIRD PARTIES BENEFITTED.

        This Agreement is made and entered into for the sole protection and
benefit of the Bank, its participants and Borrower, their successors and
assigns, and no other Person or Persons shall have any right of action hereon.

5.5. ACTIONS.

        The Bank shall have the right to commence, appear in or defend any

                    ADDITIONAL REQUIREMENTS - DISBURSEMENTS

6.1. CONSTRUCTION CONTRACT.

        Borrower shall assign to the Bank the rights of Borrower under the
Construction Contract.

6.2. CASUALTY: RESTORATION.

        In the event the Property or any of the improvements are damaged by
flood, earthquake, fire, wind or by any other means, including acts of God or
acts of the Borrower or acts of any other person, persons or thing, Borrower
agrees to (i) pay off the Loan; or (ii) restore said Property and Vacuum Unit
to substantially the condition in which it was before such damage or
destruction. Should any of the contingencies set forth in this clause occur,
Bank shall not be obligated to make any further Advances under this Agreement
until after the Property and Vacuum Unit have been restored to the same
condition they were in before the happening of such contingency, which
restoration Borrower agrees to accomplish by the use of funds other than the
hereinabove undisbursed Loan funds. If within sixty (60) days from the
happening of such contingency restoration is not accomplished, or if Borrower
has not within such sixty (60) day period taken such action as may be
appropriate under the circumstances to commence restoration and prosecute such
restoration to completion with diligence and continuity, said failure to
restore or commence restoration shall constitute a default by Borrower under
the terms of this Agreement.

        THIS DEED OF TRUST is made as of May 26, 1994, BETWEEN TESORO ALASKA
PETROLEUM COMPANY, A DELAWARE CORPORATION, whose address is 8700 Tesoro Drive,

        WITNESSETH:  That Trustor GRANTS, BARGAINS, SELLS and CONVEYS TO THE
TRUSTEE IN TRUST WITH POWER OF SALE, all of Trustor's estate, right, title and
interest now owned or hereafter acquired, in and to the following property and

TOGETHER with the buildings, improvements, tenements, hereditaments, and

TO HAVE AND TO HOLD the same, with the appurtenances, unto the Trustee;

(the "Property").

        Trustor shall be entitled to possession of the Property from and after
the execution of this Deed of Trust, and for so long as all payments on the
Note herein referred to are currently paid, and all promises, conditions and
covenants of the Trustor herein are faithfully kept and performed and no Event
of Default under the Loan Agreement between Trustor and the Beneficiary of even
date (the "Loan Agreement") has occurred and is continuing.  Terms defined in
the Loan Agreement are used herein with the same meanings.

        A.  THIS DEED OF TRUST IS MADE FOR THE PURPOSE OF SECURING:

        1.  The payment and performance of each agreement of Trustor contained
herein or in any of the Loan Documents (but specifically excluding Section 8 of
the Loan Agreement to the extent set forth therein), and payment of the
indebtedness evidenced by the Note of even date herewith in the principal
amount of $15,000,000, which amount is expected to be disbursed over a period

Agreement of even date between Trustor and Beneficiary, with interest thereon,
payable to the order of the Beneficiary, evidencing the Loan and all renewals,
extensions, modifications, and replacements thereto (the "Note").

        2.  The repayment of any and all sums and amounts



                                     -1-
<PAGE>   2
                          
that may be advanced or expenditures that may be made by the Beneficiary for
the maintenance or preservation of the Property, or any part thereof,
encumbered by this Deed of Trust, or for the enforcement of Trustor's rights
under this Deed of Trust or the Note secured hereby, as well as any sums and
amounts that may be expended by the Beneficiary pursuant to any provision of
this Deed of Trust or any other Loan Document.

        B.  TO PROTECT THE SECURITY OF THIS DEED OF TRUST, THE TRUSTOR AGREES:

        1.  PRESERVATION OF THE PROPERTY; USE OF THE PROPERTY.  To keep the
Property in good condition and repair; not to remove or demolish any building
thereon; to complete or restore promptly and in good and workerlike manner any
building which may be constructed, damaged or destroyed thereon and to pay when
due all claims for labor performed and materials furnished therefore; to comply
with all laws materially affecting the Property or requiring any alterations or
improvements to be made thereon; not to commit or permit waste thereof; not to
commit, suffer or permit any act upon the Property in material violation of
law; the specific enumerations herein not excluding the general.

        Unless required by applicable law or unless the Beneficiary has
otherwise agreed in writing, Trustor shall not allow material changes in the
use for which all or any part of the Property was intended at the time this
Deed of Trust was executed.  Trustor shall not initiate or acquiesce in a
change in the zoning classification of the Property without the Beneficiary's
prior written consent.

        2.  INSURANCE.  To provide, maintain and deliver to the Beneficiary
policies of fire and other insurance satisfactory to and with loss payable to
the Beneficiary in an amount and with companies satisfactory to the Beneficiary
which are duly authorized to write such insurance in Alaska, in accordance with
Section 5.9 of the Loan Agreement.  At least thirty (30) days prior to the
expiration of any such insurance policy, a policy or policies renewing or
extending such expiring insurance shall be delivered to the Beneficiary
together with a receipt showing payment of the premium therefor.  By executing
this Deed of Trust, the Trustor specifically authorizes the Beneficiary to
obtain the insurance in the event any required insurance policy is not provided
to Beneficiary, and a receipt for payment of the premium therefor be not so
delivered to the Beneficiary by the Trustor after written request by the
Beneficiary therefor; but the Beneficiary shall be under no obligation to do
so, and the obtaining of any insurance and the payment of the premium therefor
by the Beneficiary shall not release Trustor from any obligation hereof, the
sole responsibility for obtaining such insurance remaining at all times that of
Trustor.  Neither the Trustee nor the Beneficiary shall be responsible for 
such insurance or for the collection of any insurance monies, or for any 
insolvency of any insurer or insurance



                                     -2-

underwriter.  Trustor shall give immediate notice to Beneficiary of any 
condemnation proceeding, or loss or damage to the Property or any right 
therein.  After an Event of Default or Incipient Event of Default, Trustor 
authorizes the Beneficiary at the Beneficiary's option, to make a claim for 
and to enter into a compromise or a settlement with respect to any proceeds 
payable as a result of condemnation, loss or damage, and Trustor shall execute
such further documents as the Beneficiary shall require in connection 
therewith.  Except as provided in Section 3 below, all proceeds payable as a 
result of condemnation, loss or damage to the Property shall be paid to the 
Beneficiary and the amount collected under any fire or other insurance policy 
may be applied by Beneficiary upon any indebtedness secured hereby and in such
order as the Beneficiary may determine, or at the option of the Beneficiary 
for the entire amount so collected or any part thereof may be released to the 
Trustor.  Such application or release shall not cure or waive any default or 
notice of default hereunder or invalidate any act done pursuant to such notice.

        3.  RESTORATION.  Provided that no Event of Default or Incipient Event
of Default exists under the Loan Agreement, the Trustor may use condemnation
and insurance proceeds to repair, reconstruct, or restore the Property.


        4.  CHARGES; LIENS.  To comply with the requirements of Section 4.4 of
the Construction Loan Agreement and except when being contested in good faith,
to pay:  before delinquency, all taxes and assessments affecting the Property;
when due, all encumbrances, charges and liens, with interest, on the Property
or any part thereof, which appear to be prior or superior hereto; all costs,
fees and expenses of this Deed of Trust.

        5.  ADDITIONAL INDEBTEDNESS.  To pay immediately and without demand all
sums expended by the Beneficiary, or the Trustee pursuant to the provisions
hereof, with interest from the date of expenditure at the Default Rate called
for in the Note.

        6.  PROTECTION OF THE BENEFICIARY'S SECURITY. Should Trustor fail to
make any payment or to do any act as herein provided, then the Beneficiary or
the Trustee, but without obligation so to do and with three (3) Business Days'
notice to or demand upon Trustor and without releasing Trustor from any
obligation hereof, may:  make or do the same in such manner and to such extent
as either may deem necessary to protect the security hereof, the Beneficiary or
the Trustee being authorized to enter upon the Property for such purposes;
appear in and defend any action or proceeding purporting to affect the security
hereof or the rights or powers of the Beneficiary, or the Trustee; pay,
purchase, contest or compromise any encumbrance, charge or lien which in the
judgment of either appears to be prior or superior hereto; in exercising any
such powers, pay necessary expenses, employ counsel and pay his reasonable
fees; and to pay all costs and expenses, including cost of evidence of title
and attorneys' fees in a reasonable sum, in 




                                     -3-
<PAGE>   4

any such action or proceeding in which the Beneficiary, or the Trustee may 
appear, and in any suit brought by the Beneficiary to foreclose this Deed 
of Trust.

        7.  TITLE.  Trustor covenants that Trustor is lawfully seised of the
Property hereby conveyed and has the right to grant, convey and assign the
Property, that the Property is unencumbered and that Trustor shall warrant and
defend generally the title to the Property against all claims and demands,
subject to any easements and restrictions listed in a schedule of exceptions to
coverage in any title insurance policy insuring the Beneficiary's interest in
the Property.

        C.  IT IS MUTUALLY AGREED THAT:

        1.  CONDEMNATION.  Any award or damages in connection with any
condemnation for public use of or injury to the Property or any part thereof,
is hereby assigned and shall be paid to the Beneficiary who may apply or
release such monies received by the Beneficiary in the same manner and with the
same effect as above provided for disposition of proceeds of fire or other
insurance.

        2.  NO WAIVER.  By accepting payment of any sums secured hereby after
its due date, the Beneficiary does not waive its right either to require prompt
payment when due of all other sums so secured or to declare default for failure
to make future payments in a timely fashion.  Any forbearance by the
Beneficiary in exercising any right or remedy hereunder or by law shall not be
a waiver of or preclude the exercise of any right or remedy for any future
default.

        3.  BORROWER AND LIEN NOT RELEASED.  At any time or from time to time,
without liability therefor and without notice, the Beneficiary, or the Trustee,
upon the Beneficiary's written request and presentation of this Deed of Trust
and the Note for enforcement, and without affecting the personal liability of
any person, whether as primary obligor, surety, or otherwise, for payment of
the indebtedness secured hereby, may: reconvey all or any part of the Property;
consent to the making of any map or plat thereof; join in granting any easement
thereon; or join in any extension agreement or any agreement subordinating the
lien or charge hereof.

        4.  RECONVEYANCE.  Upon Beneficiary's written request stating that all
sums secured hereby have been paid, and upon surrender of this Deed of Trust
and Note secured hereby to the Trustee for cancellation and retention and, upon
payment of its fees, the Trustee shall reconvey, without warranty, the Property
then held hereunder.  The recitals in any reconveyance executed under this Deed
of Trust of any matters or facts shall be conclusive proof of the truthfulness
thereof.  The grantee in such reconveyance may be described as "the person or
persons legally entitled thereto."

        5.  APPOINTMENT OF RECEIVER; BENEFICIARY IN POSSESSION.  Upon the
occurrence and during the continuance of any Event of Default, the Beneficiary
may at any time without notice, either in person, by agent, or by a receiver to
be appointed by a court, and without regard to the adequacy of any security for
the indebtedness hereby secured, enter upon and take possession of the Property
or any part thereof, sue for or otherwise collect rents, issues and profits,
and apply the same, less costs and expenses of operation and collection and in
such order as the Beneficiary may determine. The entering upon and taking
possession of the Property, the collection of such rents, issues and profits
and the application thereof as aforesaid, shall not cure or waive any default
or notice of default hereunder or invalidate any act done pursuant to such
notice.  In addition to all of the other rights and powers provided herein, the
Beneficiary may in its discretion commence legal proceedings to recover
possession of the Property.  In no event shall the Beneficiary be under any
obligation to invoke any of the foregoing remedies.

        6.  DEFAULT; ACCELERATION.  Upon the occurrence and during the
continuance of any Event of Default, as defined in the Loan Agreement, the
Beneficiary may, by written notice to the Borrower, declare all sums secured
hereby to be due and payable.  In the Event of Default, the Beneficiary may
execute or cause the Trustee to execute a written notice of such default and of
its election to cause to be sold the Property to satisfy the obligation hereof,
and may cause such notice to be recorded in the office of the recorder for the
recording district in which the Property or some part thereof is located.

                Notice of sale having been given as then required by law and
not less than the time then required by law having elapsed after recordation of
such notice of default, the Trustee, without demand on Trustor, shall sell the
Property at the place provided by law and at the time fixed by the Trustee in
the notice of sale, either as a whole or in separate parcels and in such order
as it may determine, at public auction to the highest and best bidder for cash
in lawful money of the United States, payable at the time of sale.  If sold in
separate parcels, they may be sold in whichever order the Beneficiary desires;
however, the order need not be specified in notice of sale, nor need the notice
specify that the Property is being sold in separate parcels.  If the Property
is sold in two or more separate parcels, any successful offset bid by the
Beneficiary shall be deducted from the total offset bidding rights of the
Beneficiary and that remaining can be applied toward bidding on each successive
parcel.  The Trustee may postpone the sale of all or any portion of the
Property by public announcement at such time and place of sale, and from time
to time thereafter may postpone such sale by public announcement at the time
fixed by the preceding postponement.  The Trustee shall deliver to the
purchaser its deed conveying the Property sold, but without any covenant or
warranty, express or implied.  The recitals in such deed of any matters or
facts shall be conclusive proof of the truthfulness thereof.  Any person,
including Trustor, the Trustee, or the 





                                     -5-
<PAGE>   6
Beneficiary as hereunder defined, may purchase at such sale.

        After deducting all costs, fees and expenses of the Trustee and of this
Trust, including cost of evidence of title and reasonable counsel fees in
connection with sale, the Trustee shall apply the proceeds of sale to payment
of:  all sums expended under the terms hereof, not then repaid with accrued
interest at the same rate provided for in the Note which this Deed of Trust
secures, and if there be more than one such Note then at the highest rate
called for in any such Note secured hereby; all other obligations then secured
hereby; and the remainder, if any, to the person or persons legally entitled
thereto.

        7.  JUDICIAL ACTION; POWER OF SALE.  Nothing contained herein shall be
construed to limit the right of the Beneficiary to foreclose this Deed of Trust
by judicial action or by exercise of the power of sale.

        8.  BINDING DEED OF TRUST.  This Deed of Trust applies to, inures to
the benefit of, and binds all parties hereto, their successors and assigns. 
The term "Beneficiary" shall mean the holder and owner, including pledgee, of
the Note secured hereby, whether or not named as a beneficiary herein, or, if
the Note had been pledged, the pledgee hereof.  In this Deed of Trust, whenever
the context so requires, the masculine gender includes the feminine or neuter,
and the singular number includes the plural.

        9.  PUBLIC RECORD.  The Trustee accepts this trust when this Deed of
Trust, duly executed and acknowledged, is made a public record as provided by
law.  The Trustee is not obligated to notify any party hereto of pending sale
under any other deed of trust or of any action or proceeding in which Trustor,
the Beneficiary, or the Trustee shall be a party unless such action or
proceeding is brought by the Trustee.

        10.  SUBSTITUTE TRUSTEE.  The Beneficiary may, from time to time, as
provided by statute, appoint another Trustee in place and stead of the Trustee
herein named, and thereupon the Trustee herein named shall be discharged and
the Trustee so appointed shall be substituted as the Trustee hereunder with the
same effect as if originally named Trustee herein.

        11.  MULTIPLE TRUSTEES.  If two or more persons be designated as the
Trustee herein, any, or all, powers granted herein to the Trustee may be
exercised by any of such persons, if the other person or persons is unable, for
any reason, to act, and any recital of such inability in any instrument
executed by any such person shall be conclusive against Trustor, its 
successors and assigns.

        12.  MATURITY DATE.  The maturity of this instrument, for purposes of
A.S. 34.20.150 or any similar statute, shall occur upon the full satisfaction
of all indebtedness and other obligations secured by this instrument, or fifty
(50) years 





                                     -6-
<PAGE>   7
from the execution of this instrument, whichever is earlier.

        13.  INSPECTION.  The Beneficiary may make or cause to be made
reasonable entries upon and inspections of the Property.

        14.  REMEDIES CUMULATIVE.  Each remedy provided in this Deed of Trust
is distinct and cumulative to all other rights or remedies under this Deed of
Trust or afforded by law or equity, and may be exercised concurrently,
independently, or successively, in any order whatsoever.

        15.  ADDRESSES FOR NOTICES.  All communications and notices provided
hereunder shall be in writing and mailed, certified U.S. Mail or delivered to
the Trustor and the Beneficiary at their respective addresses first set forth
above or, as to any party, at such other address as shall be designated by such
party in a written notice to the other parties complying as to delivery with
the terms of this paragraph.  All such communications and notices shall be
effective upon receipt.

        16.  WAIVER OF MARSHALLING.  Notwithstanding the existence of any other
security interests in the Property held by Beneficiary or by any other party,
the Beneficiary shall have the right to determine the order in which any or all
of the Property shall be subjected to the remedies provided herein.  The
Beneficiary shall have the right to determine the order in which any or all
portions of the indebtedness secured hereby are satisfied from the proceeds
realized upon the exercise of the remedies provided herein. Trustor, any party
who consents to this Deed of Trust and any party who now or hereafter acquires
a security interest in the Property and who has actual or constructive notice
hereof hereby waives any and all right to require the marshalling of assets in
connection with the exercise of any of the remedies permitted by applicable law
or provided herein.

        17.  NO SALE, LEASING OR TRANSFER OF THE PROPERTY. Except as provided
in the Loan Agreement, if all or any part of the Property subject to this Deed
of Trust, or any interest therein, is sold, leased or transferred by Trustor
without Beneficiary's prior written consent, Beneficiary may, at Beneficiary's
option, declare all of the sums secured by this Deed of Trust to be immediately
due and payable.  Nothing herein shall be construed as limiting Beneficiary's
right to accelerate regardless of whether or not the person or entity to whom
the Property was sold or transferred has satisfactory credit or is willing to
agree to any particular rate of interest.

        If Beneficiary exercises such option to accelerate, Beneficiary shall
mail Trustor notice of acceleration at Trustor's last known address as
disclosed by the record of the holder of the Note secured by this Deed of
Trust.  Such notice shall provide a period of not less than thirty (30) days
from the date of the notice during which the Trustor may pay the sums declared
due.  If 





                                     -7-
<PAGE>   8
Trustor fails to pay such sums prior to the expiration of such period, 
Beneficiary may, without further notice or demand on Trustor, invoke any 
remedies permitted, this Deed of Trust or the Note, as well as all other 
remedies permitted under the law.

        18.  ESTOPPEL CERTIFICATE.  Trustor shall within ten (10) days of a
written request from Beneficiary, furnish Beneficiary with a written statement,
duly acknowledged, setting forth the sums secured by this Deed of Trust and any
right of set-off, counterclaim or other defense which exists against such sums
and the obligations of this instrument.

        19.  UNIFORM COMMERCIAL CODE SECURITY AGREEMENT. All fixtures to the
Property are also subject to a security interest in favor of the Beneficiary
under a separate Security Agreement of even date.

        DATED as of the date first above written.

                                                               Exhibit 4.35

                               SECURITY AGREEMENT

        THIS SECURITY AGREEMENT ("Agreement") made as of May 26, 1994, by and
between NATIONAL BANK OF ALASKA, a National Banking Association, whose address
is P. O. Box 100600, Anchorage, Alaska 99510, ("Bank"), and TESORO ALASKA
PETROLEUM COMPANY, a Delaware  corporation, whose address is 8700 Tesoro Drive,
San Antonio, Texas 78217 (the "Debtor").

        THE PARTIES AGREE AS FOLLOWS:

        1.  DEFINITIONS.  As used in this Agreement:

                a.  A "Default" means an Event of Default described in Section
        7.1 of the Loan Agreement;

                b.  The "equipment" means goods which are used or bought for
        use primarily in business, including all parts, equipment, machinery
        and furniture, and all accessions and additions thereto;

                c.  The "Loan Agreement" means that loan agreement between the
        Bank, the Debtor, and the Guarantor as amended from time to time of
        even date;

                d.  A "Security Interest" means an interest in personal
        property which secures payment or performance of an obligation;

                e.  Terms defined in the Loan Agreement are used herein with
        the same meanings.

        2.  OBLIGATION.  The obligation ("Obligation(s)") of the Debtor
consists of: the Note executed and delivered by the Debtor to the Bank, in the
principal amount of FIFTEEN MILLION AND NO/100 DOLLARS ($15,000,000) and all
conversions, renewals and extensions thereof,  and all other obligations of
Debtor under the Loan Documents now owed or hereafter owing, including the
Banks's expenses arising hereunder.

        3.  COLLATERAL; HYPOTHECATION; GRANT OF SECURITY INTEREST.  In
consideration of the financial accommodations by the Bank to the Debtor and to
secure full payment and performance by the Debtor including but not limited to 
the Obligations and duties set forth herein, the Debtor hereby pledges,
hypothecates, assigns and grants a continuing lien and security interest to the
Bank in the following as collateral ("Collateral"):

                 All of Debtor's present and after-acquired interests in
                 equipment, fixtures, and licenses for the Refinery (to 
                 the extent allowed by 





                                     -1-
<PAGE>   2
                 law), together with all proceeds, including, without 
                 limitation, proceeds of insurance policies and  
                 substitutions, additions, and replacements for all of
                 such properties, renewals, and extensions thereof, 
                 wherever located. The real estate to which the 
                 Collateral is related is described in Exhibit A hereto.


        4.  TITLE AND TYPE OF COLLATERAL.  The Debtor warrants that it is the
owner of the Collateral free from any adverse lien, security interest or
encumbrance, except for the security interests naming Bank as the secured party
or permitted under the Loan Agreement.  The Debtor will defend the Collateral
against any claims and demands of all persons at any time claiming same or any
interest therein.  The Collateral is used or bought for use primarily for
business purposes and it shall be kept in the State of Alaska.  The Collateral
is not and shall not be used for personal, family, household, or farming uses. 
The Debtor will not remove the Collateral from the State of Alaska without the
Bank's prior written consent.  In the event of any such move, the Bank's
security interest shall remain a perfected lien of first priority.

        5.  NO OTHER NAMES.  The Debtor has not conducted business under any
name except the name in which it has executed this Agreement and Tesoro-Alaskan
Petroleum Corporation.  The Debtor will not change its name or principal place
of business without the written consent of the Bank.  In the event of any such
change, the Bank's lien on the collateral shall continue as a perfected lien of
first priority.

        6.  RECORDS AND REPORTS.  The Debtor will maintain complete and
accurate books and records with respect to the Collateral, and furnish to the
Bank such reports relating to the Collateral as the Bank may from time to time
request.

        7.  INSURANCE AND RISK OF LOSS.  The risk of loss of the Collateral
shall be on the Debtor, who will have and maintain insurance for the benefit of
the Bank, as its interest may appear, as loss payee and as additional insured,
at all times with respect to such Collateral and against such risk, and in such
companies and in such amounts as may be satisfactory to the Bank, all as set
forth in Section 5.9 of the Loan Agreement which is incorporated herein by
reference.  Upon ten (10) days' written notice from the Bank, the Debtor shall
deliver to the Bank certificates or other evidence satisfactory to the Bank of
compliance with the foregoing insurance provisions and pay for the costs of all
such insurance.  The Debtor hereby assigns to the Bank all right to receive
proceeds of all insurance and after an Event of Default or Incipient Event of 
Default adjust and settle all losses thereunder and directs any 



                                     -2-
<PAGE>   3
insurer to pay all such proceeds directly to the Bank and authorizes the Bank 
to endorse any draft for such proceeds.  If no Event of Default or Incipient 
Event of Default exists under the Loan Agreement, the Debtor may use insurance 
proceeds to repair, reconstruct, or restore the Collateral

        8.  POSSESSION AND USE.  Until the occurrence and continuance of a
Default, the Debtor may have possession of the Collateral and use it in any
lawful manner not inconsistent with this Agreement or any policy of insurance
thereon or any law of the State of Alaska or the United States of America.  The
Debtor shall keep the Collateral in good order and repair and will not waste or
destroy it or any part thereof.  The Bank, its representatives and agents, may
examine and inspect the Collateral at any time wherever located, to examine and
make copies of the Debtor's records relating thereto, to discuss with and to be
advised by, the Debtor's officers and employees, the Collateral, and the
Debtor's records with respect thereto, all at such reasonable times and
intervals as the Bank may determine, all at the Debtor's expense.

        9.  TAXES AND ENCUMBRANCES.  The Debtor will pay before delinquent all
taxes, assessments, liens or encumbrances, governmental or private, levied upon
the Collateral or for its use or operations or under this Agreement, unless the
same are being contested in good faith.  So long as any part of the Obligations
are outstanding, the Debtor will not, without the Bank's prior written consent,
(a) permit any liens or security interest (other than the liens arising under
or permitted by this Agreement or any other liens permitted in the Loan
Agreement) to attach to any of the Collateral; (b) permit any of the Collateral
to be levied upon under any legal process; (c) permit anything to be done that
may impair the value of any of the Collateral or the security intended to be
afforded by this Agreement; or (d) permit the Collateral to be a fixture except
to the Refinery, or to become an accession to other goods except goods covered
by this Agreement.

        10.  FILING.  The Debtor warrants that no financing statement covering
any Collateral or any proceeds thereof is on file with any public office,
except for financing statements related to liens permitted by the Loan
Agreement, and agrees, at its expense, to join with the Bank in executing a
financing statement, notice, affidavit, or similar instrument in form
satisfactory to the Bank, and such other instruments, as the Bank may from time
to time request; and further agrees to pay the cost of filing the same in any
public office deemed advisable by the Bank.  A copy of this Agreement may be
filed in lieu of a financing statement.  The Bank hereby agrees to execute a
termination statement upon the payment in full of the Obligations.

        11.  DEFAULT.  Upon the occurrence, and during the continuance of a
Default, the Bank may, in addition to any other



                                     -3-
<PAGE>   4
rights and remedies which it may have, immediately and without demand, 
exercise any and all of the rights and remedies granted to a secured party 
upon default under the Uniform Commercial Code.

        The Bank may require the Debtor to assemble its Collateral and make it
available to the Bank at the Refinery.  The Debtor shall pay to the Bank, upon
demand, any and all costs and expenses, including legal expenses and reasonable
attorneys' fees incurred or paid by the Bank in protecting or enforcing
liabilities and the Bank's rights hereunder, including the Bank's right to take
possession of the Collateral and to hold, prepare for sale, sell and dispose of
such Collateral.  Any notice of sale, disposition, or other intended action by
the Bank sent to the Debtor at the address specified in the preamble, or such
other address of the Debtor as may from time to time be shown on the Bank's
records and received by the Debtor, at least ten (10) days prior to such
action, shall constitute reasonable notice to the Debtor.

        12.  WAIVERS, AMENDMENTS AND REMEDIES.  No delay or omission of the
Bank to exercise any right or remedy granted under this Agreement or under
applicable law shall impair such right or remedy or be construed to be a waiver
of any Default or an acquiescence therein, and any single or partial exercise
of any such right or remedy shall not preclude other or further exercise
thereof or the exercise of any other right or remedy, and no waiver, amendment
or other variation of the terms, conditions or provisions of this Agreement
whatsoever shall be valid unless in writing signed by the Bank, and then only
to the extent in such writing specifically set forth.  All rights and remedies
contained in this Agreement or by law afforded shall be cumulative and all
shall be available to the Bank until the Obligations have been paid in full. 
In the event of any conflict between this Agreement and the Loan Agreement, the
provisions of the Loan Agreement shall apply.

        13.  BANK'S PERFORMANCE OF DEBTOR'S OBLIGATIONS.  Upon Default, or at
any time the Debtor fails to perform as required hereunder or under any other
of the Loan Documents, without having any obligation to do so, the Bank, upon
three (3) Business Days notice, may perform or pay any obligation which the
Debtor has agreed to perform or pay in this Agreement and the Debtor shall
reimburse the Bank for any amounts paid by the Bank, with interest at the
Default Rate, pursuant to this Section.  The Debtor's obligation to reimburse
the Bank pursuant to the preceding sentence shall be an Obligation payable on
demand.

        14.  AUTHORIZATION FOR BANK TO TAKE CERTAIN ACTION.  The Debtor
irrevocably authorizes after an Event of Default or Incipient Event of Default
the Bank at any time and from time to time in the Bank's sole discretion and
appoints the Bank as its attorney in fact to act on behalf of the Debtor: (i)
to execute on 





                                     -4-
<PAGE>   5
behalf of the Debtor as debtor and to file financing statements necessary or 
desirable in the Bank's sole discretion to perfect and to maintain the 
perfection and priority of the Bank's security interest in the Collateral; 
and (ii) to apply the proceeds of any Collateral received by the Bank to the 
Obligations.

        15.  HEADINGS.  The title of and section headings in this Agreement are
for convenience of reference only, and shall not govern the interpretation of
any of the terms and provisions of this Agreement.

        16.  TERM.  This Agreement and the lien arising hereunder (i) shall
become effective as of the date hereof upon the execution hereof, and (ii)
shall continue in force for so long as any Obligations, or commitment to extend
any Obligations, remain outstanding.

        17.  INDEMNITY.  The Debtor hereby agrees to assume liability for, and
does hereby agree to indemnify and keep harmless the Bank, its successors,
assigns, agents and employees, from and against any and all liabilities,
damages, penalties, suits, costs, and expenses of any kind and nature, imposed
on, incurred by or asserted against Bank, or its successors, assigns, agents
and employees, in any way relating to or arising out of this Agreement, any
transactions contemplated by this Agreement including, without limitation, the
realization and sale of the Collateral.

        18.  WAIVERS.  The Debtor waives, to the extent permitted by applicable
law: (i) any right to require the Bank to proceed against any other person, to
exhaust its rights in any other Collateral, or to pursue any other right which
either the Bank may have, (ii) except to the extent expressly otherwise
provided herein or in the Loan Agreement, with respect to the Obligations,
presentment and demand for payment, protest, notice of protest and non-payment,
and notice of the intention to accelerate, and (iii) all rights of marshalling
in respect of any and all of the Collateral.

        19.  DEFICIENCY.  The Debtor shall be liable to pay any deficiency
resulting from disposition of the Collateral by the Bank upon Default. 
However, the Bank may pursue collection of the outstanding indebtedness without
initially seeking satisfaction from the Collateral.

        20.  CHOICE OF LAW.  The parties hereby agree and designate the laws of
the State of Alaska as the applicable law for construction of the validity,
terms or performance of this Agreement.

        21.  SEVERABILITY.  The provisions of this Agreement are severable, and
if a provision is held invalid or unenforceable by 





                                     -5-
<PAGE>   6
a court of competent jurisdiction, such invalidation or unenforceability shall 
not affect or impair any of the remaining provisions.

        22.  SUCCESSORS AND ASSIGNS.  All of the rights of the Bank hereunder
shall inure to the benefit of its successors and assigns; and all obligations
of the Debtor shall bind its successors and assigns.

                      CONSENT AND INTERCREDITOR AGREEMENT

        THIS CONSENT AND INTERCREDITOR AGREEMENT is made as of May 26, 1994 by
and among NATIONAL BANK OF ALASKA ("NBA") and TEXAS COMMERCE BANK NATIONAL
ASSOCIATION as Agent (the "Agent") for the Lenders pursuant to the Credit
Agreement (as defined below) and TESORO PETROLEUM CORPORATION ("Company").

                                R E C I T A L S

        A.  The Company, Texas Commerce Bank National Association,
individually, as an Issuing Bank and as Agent, Banque Paribas, individually, as
an Issuing Bank and as Co-Agent, and the lenders (the "Lenders"), now or
hereafter parties thereof, have entered into that certain Credit Agreement as
of April 20, 1994 (as the same may be amended or restated from time to time,
the "Credit Agreement").  To secure the Company's obligations under the Credit
Agreement and related documents, Tesoro Alaska executed a Security Agreement as
of April 20, 1994 pursuant to which Tesoro Alaska granted to the Lenders a
security interest in the Kenai Refinery and fixtures, equipment and other
personal property related thereto.  Terms not otherwise defined herein shall
have the same meaning as defined in the Credit Agreement.

        B.  The terms of the Credit Agreement limit the Company and Tesoro
Alaska's ability to incur additional indebtedness, to grant additional liens,
and to make certain capital expenditures.

        C.  NBA has agreed to provide a loan to Tesoro Alaska in the principal
amount of Fifteen Million Dollars ($15,000,000) guaranteed by the Company, the
proceeds of which are to be used for construction of a Vacuum Unit at the Kenai
Refinery (the "Loan").  NBA will participate the Loan with the Alaska
Industrial Development & Export Authority.  The Loan is evidenced by a loan
agreement executed by and between NBA, the Company, and Tesoro Alaska dated as
of May 26, 1994 (as the same may be amended or restated from time to time
hereafter pursuant to the terms hereof, the "NBA Loan Agreement").  Tesoro
Alaska's obligations to repay the Loan are secured with (a) a lien in and to
the Kenai Refinery, (b) equipment owned by Tesoro Alaska which is dedicated for
use at or in connection with the Refinery, and (c) the proceeds and products
thereof ("Proceeds"), which proceeds and products do not include accounts or
inventory.  The Kenai Refinery, the Equipment, and the Proceeds are referred to
herein as the "Collateral" and the security interest in the Collateral granted
to NBA to secure the repayment of the Loan is referred to herein as the "NBA
Security Interest."  NBA does not intend to now or hereafter take a security
interest in the Company's, Tesoro Alaska's or any of the Company's other
subsidiaries' accounts or inventory as security for the Loan.

        D.  As a condition to making the Loan, NBA requires that Lenders
subordinate their security interests in the Collateral to the NBA Security
Interest.  The Credit Agreement permits Tesoro Alaska to incur the Loan and to
grant a prior lien in the Collateral to NBA, subject to documentation,
including this Agreement, satisfactory to the Agent.  The Lenders are willing
to subordinate their lien in the Collateral, subject to the terms, conditions
and covenants which follow.

        NOW, THEREFORE, the parties agree as follows:

                               A G R E E M E N T

                                       I.

                          SUBORDINATION AND STANDSTILL

        Section 1.01  Subordination.  Lenders hereby subordinate the lien of
the Lenders in and to the Collateral to the NBA Security Interest.  Subject to
the terms of this Agreement, this subordination will be effective and continue
until the Loan is paid in full.

        Section 1.02  Notice  The Agent agrees that promptly after it sends any
notice of a Default or of an exercise or an intention to exercise remedies to
the Company or Tesoro Alaska, that it shall promptly provide a copy of such
notice to NBA.

        Section 1.03  Subordination and Standstill Not Affected. NBA shall not
be required to continue to lend money or to extend other credit to Tesoro
Alaska; to resort for payment or to proceed directly at any time against any
person, including Tesoro Alaska or any guarantor; to proceed directly or
exhaust any collateral held by NBA from Tesoro Alaska, any guarantor or any
other person; or to take any action to enforce or collect the NBA security
interest in order to maintain the effectiveness of the obligations under this
Article I.

                                      II.

                          LENDERS' CONSENT AND WAIVER

        Section 2.01  Consent to Indebtedness.  Lenders hereby consent to
Tesoro Alaska's incurring the obligations to repay the Loan to NBA.  This
consent is limited to the obligation to repay the maximum principal amount of
Fifteen Million Dollars ($15,000,000).

        Section 2.02  Consent to Liens.  Lenders consent to Tesoro Alaska's
grant to NBA of a lien on the Collateral provided that such lien secures only
the repayment of the Loan and related




                                      2
<PAGE>   3
obligations arising under the NBA Loan Agreement and related documents.

                                      III.

                          ACKNOWLEDGMENT AND AGREEMENT

        Section 3.01  Acknowledgement of Lien.  NBA acknowledges the lien of
the Lenders on the Collateral.  Except as expressly set forth in this Consent
and Intercreditor Agreement, NBA shall have no duties to the Lenders.

        Section 3.02  Exercise of Remedies.  NBA agrees for the benefit of the
Agent and the Lenders that it shall not accelerate the maturity of the Loan or
take any action against the Collateral including, without limitation,
foreclosure or other enforcement of its lien thereon, unless and until one of
the following shall have occurred and continuing:

                (i) An Event of Default pursuant to Section 7.1.1 (which Event
        of Default shall not have been cured within 30 days after written
        notice thereof by NBA to the Agent or 7.1.6 of the NBA Loan Agreement.

                (ii) The indebtedness owing pursuant to the Credit Agreement
        shall have been accelerated.

                (iii) An Event of Default pursuant to Section 7.1 (other than
        Section 7.1.1 and 7.1.6) of the NBA Loan Agreement to the extent, but
        only to the extent such an Event of Default (or the underlying
        representation, warranty, covenant or agreement resulting in such Event
        of Default) has a corresponding provision under the Credit Agreement
        (each a "Credit Agreement Provision"), and such Event of Default under
        the NBA Loan Agreement has continued for 30 days after written notice
        to the Agent by NBA or the Company without being cured; provided if
        during such period the corresponding Credit Agreement Provision shall
        be waived (or the Credit Agreement shall be amended in such a way that
        the Event of Default under the Credit Agreement no longer continues)
        the Event of Default under the NBA Loan Agreement shall, subject to the
        provisions of Section 3.03, be automatically waived to the same extent
        provided further in the event additional collateral is pledged or other
        consideration paid in connection with such waiver or amendment to the
        Agent, the Issuing Banks, or the Lenders under the Credit Agreement,
        NBA shall not be entitled to participate in any such additional
        security or consideration except as provided in Section 3.03.

        Section 3.03  Certain Fees, Prepayments and Covenants.  The Company
agrees that, at the option of NBA, any prepayment made by the Company to the
Lenders (other than a mandatory prepayment made pursuant to Section 2.10(a) or
Section 2.10(b) of the Credit Agreement) in connection with, or any fee paid by
the Company to the Lenders as consideration for, a waiver of an Event of
Default under the Credit Agreement or an amendment of a Credit Agreement
Provision in response to an Event of Default Waiver pursuant to Section
3.02(iii), the Company shall make or cause Tesoro Alaska to make an additional
prepayment, or pay an additional fee (as the case may be), to NBA of the Loan
on prorata basis calculated on the outstanding balance of the Loan from NBA and
the Maximum Available Amount as defined in the Credit Agreement each as of the
date of the Event of Default or, if such date cannot be determined, the date of
the notice of the Event of Default.  If, as a condition of waiver or amendment
of the Credit Agreement as provided herein, the Credit Agreement is amended to
add or amend covenants (except for covenants providing for additional
collateral) which have the effect of increasing the limitations or burdens on
the Company similar additions or amendments shall, at the option of NBA, be
required for the waiver of the Event of Default under the NBA Loan Agreement.

                                      IV.

                            MISCELLANEOUS PROVISIONS

paid in full, NBA shall execute all instruments and documents which Lenders may
reasonably request to evidence the termination of NBA's Security Interest.

         Section 4.02  No Waiver; Remedies Cumulative.  No failure by NBA or
the Lenders to exercise, and no delay in exercising, any right, power or remedy
under this Agreement shall operate as a waiver thereof, nor shall any single or
partial exercise of any right, power or remedy under this Agreement preclude
any other or further exercise thereof or the exercise of any other right, power
or remedy.

        Section 4.03  Governing Law.  This Agreement shall be governed by and
construed in accordance with the internal laws of the State of Alaska.

        Section 4.04  Severability.  Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall as to such jurisdiction
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof or affecting the validity or
enforceability of such provision in any other jurisdiction.  To the extent
permitted by applicable law, the parties waive any provision of law which





                                      4

        Section 4.05  Executed in Counterpart.  This Agreement may be executed
in any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original,
and all of which taken together shall constitute one and the same Agreement.
