                                  THE COMPANY
 
     The Company is an independent refiner of petroleum and petroleum
derivatives and produces high value light products such as gasoline, diesel fuel
and jet fuel for sale primarily in the southwestern United States and northern
Mexico. The Company owns a high-conversion petroleum refinery in Artesia, New
Mexico, which it operates in conjunction with crude, vacuum distillation and
other facilities situated 65 miles away in Lovington, New Mexico. The Navajo
Refinery has a crude capacity of 60,000 barrels per day ("BPD") and can process
a variety of high sulfur ("sour") crude oils. For the last three fiscal years,
sour crude oils have represented approximately 85% of the crude oils processed
by the Navajo Refinery. The Navajo Refinery's processing capabilities enable
management to vary its crude supply mix to take advantage of changes in raw
materials prices and to respond to fluctuations in the availability of crude oil
supplies. The Navajo Refinery converts approximately 86% of its raw materials
throughput into high value light products. For fiscal 1994, including barrels
purchased for resale, gasoline, diesel fuel and jet fuel represented 56.5%,
19.7% and 11.1%, respectively, of Navajo's sales volume. For the last three
fiscal years, excluding downtime for scheduled maintenance and turnarounds, the
Navajo Refinery has operated at an average annual crude capacity utilization
rate of approximately 93%.
 
     The Artesia facility is located on a 300-acre site and has fully integrated
crude, fluid catalytic cracking ("FCC"), vacuum distillation, alkylation,
hydrodesulfurization and reforming units, and approximately 1.5 million barrels
of feedstock and product tank storage. The Lovington facility is operated as an
integrated component of the Navajo Refinery and refines crude oil into
intermediate products, which are transported, primarily via a Company-owned
pipeline, to the Artesia facility for further processing. Navajo's assets also
include a 500-mile crude oil gathering pipeline system, 30 crude oil and product
tank trucks, three refined products pipelines and product storage at terminals
in Tucson, Albuquerque, Artesia and El Paso in which the Company has 50% or
greater interests.
 
     The Company also owns a 7,000 BPD petroleum refinery near Great Falls,
Montana, which can process a range of crude oils and which serves primarily the
State of Montana. For fiscal 1994, including barrels purchased for resale,
gasoline, diesel fuel, asphalt and jet fuel represented 38.6%, 24.3%, 18.6% and
15.7% of MRC's sales volume. For the last three fiscal years, excluding downtime
for scheduled maintenance and turnarounds, the Montana Refinery has operated at
an average annual crude capacity utilization rate of approximately 94%.
 
     In addition to its refining operations, the Company also conducts a
small-scale oil and gas exploration and production program.

<PAGE>   6
 
     Despite fluctuating industry conditions, the Company, which was
incorporated in 1947 and acquired the Navajo Refinery in 1969, has generated
positive net income for each of the past 24 years. The Company had net income
and cash from operating activities of $24.0 million and $33.6 million,
respectively, for fiscal 1990, $11.7 million and $27.9 million for fiscal 1991,
$2.8 million and $1.0 million for fiscal 1992, $19.0 million and $38.7 million
for fiscal 1993, and $20.7 million and $27.7 million for fiscal 1994. The
Company believes that it has certain business strengths that have contributed to
its history of profitable operations. Among those strengths are the following:
 
    - Geographic location/attractive markets. The Navajo Refinery serves
      primarily the growing southwestern United States market, including El
      Paso, Albuquerque, Phoenix and Tucson, which generally has favorable
      supply and demand characteristics compared to Gulf Coast markets, and the
      northern Mexico market, which is expected to experience demand growth over
      the next several years. According to data compiled by the United States
      Bureau of the Census, from April 1, 1990 to July 1, 1993, the population
      of the Navajo Refinery's principal market area in the U.S. (Arizona, New
      Mexico and El Paso) grew at a compound annual rate of 2.2%, compared to a
      nationwide compound annual growth rate of 1.1% during that period. From
      April 1, 1980 to July 1, 1993, this area grew at a compound annual rate of
      2.5%, compared to a nationwide rate of 1.0%. The Montana Refinery serves
      primarily the State of Montana, which also historically has had relatively
      favorable supply and demand characteristics.
 
    - High conversion refinery. The Navajo Refinery converts approximately 86%
      of its raw materials throughput into high value light products from a
      variety of sour crude oils and can vary the refined products it produces
      to respond to fluctuations in demand. The Navajo Refinery's processing
      capabilities also enable management to vary its crude supply mix to take
      advantage of changes in raw materials prices and to respond to
      fluctuations in the availability of crude oil supplies. For the last three
      fiscal years, sour crude oils have represented approximately 85% of the
      crude oils processed by the Navajo Refinery.
 
    - Raw material supply. Located on the northwestern shelf of the Permian
      Basin, the Navajo Refinery has direct access to a historically reliable
      crude oil supply, which is transported to the refinery primarily through a
      500-mile, Company-owned crude oil pipeline gathering system and by crude
      oil tank trucks. The Company's crude oil pipelines connect to tankage
      facilities in New Mexico and Texas and are connected to, or are located in
      proximity to, a number of common carrier crude oil pipelines. The Montana
      Refinery obtains most of its crude oil via a 93-mile, Company-owned
      pipeline which runs from near the Canadian border.
 
    - Distribution logistics. The Company distributes refined products from the
      Navajo Refinery to its principal markets primarily through (i) a
      Company-owned pipeline extending from Artesia to El Paso and (ii) a
      Company-owned pipeline extending from Artesia to Orla, Texas, and from
      there west to El Paso. Products can be shipped by pipeline from El Paso to
      Albuquerque via a products pipeline system owned by Chevron Pipeline
      Company, and to Tucson and Phoenix via a products pipeline system owned by
      Santa Fe Pacific Pipeline. The Company also owns a segment of a products
      pipeline running from Orla to Odessa, Texas, which is currently inactive.
      The Company believes that the proximity of the Navajo Refinery to its
      principal markets and the refinery's products distribution network provide
      a transportation cost advantage over Gulf Coast and West Coast refineries
      in supplying its markets.

                               BUSINESS STRATEGY
 
     The Company's strategy has been, and continues to be, to optimize its
refinery operations to increase the proportion of high value products it
produces and to lower operating costs. As part of this strategy, the Company
completed a $63 million expansion of the Navajo Refinery in December 1991,
which, among other things, increased its refining capacity from 40,000 to 60,000
BPD. That expansion consisted principally of the addition of a new continuous
catalytic regeneration unit, the modification of the FCC unit, the expansion of
the naphtha desulfurizer and the installation of new sulphur and alkylation
units. The installation of new equipment and the modification and upgrading of
existing equipment as part of that expansion program increased the proportion of
sour crude oils that the Navajo Refinery can process and increased the
proportion of its throughput that can be converted into higher value products.
 
     The Company continues to evaluate improvements to its operating cost
structure, refineries and crude oil gathering and product distribution systems.
Management believes that certain enhancements and additions to the Navajo
Refinery should better position the Company to respond to competitive pressures
and to meet possible increases in demand for refined products. As part of its
strategy, management intends to spend approximately $15 million over an 18-month
period on identified capital enhancement projects at the Navajo Refinery. Those
projects involve upgrades to the FCC and alkylation units, the construction of
an isomerization unit and the installation of a new selective hydrogenation
process ("SHP") unit. Management expects these projects to increase the Navajo
Refinery's total gasoline production and to improve its ability to produce a
greater proportion of "premium" (high octane) gasoline. In addition, these
enhancements and plant additions are expected to improve management's
flexibility to operate using different types of crude oils and other raw
materials and to provide a platform for further refinery expansion, if
appropriate, in the future. In addition, the Company is evaluating a number of
other possible capital improvement projects, including (i) the redistribution of
process activities between the Lovington and Artesia facilities in order to
realize potential operating and transportation cost savings, (ii) other upgrades
to improve the efficiency of the Navajo Refinery, (iii) modifications to
increase product pipeline distribution capacity and (iv) product pipeline
reconditioning and construction to facilitate entry into new markets. See
"Capital Improvement Projects."

                           INVESTMENT CONSIDERATIONS
 
     Prospective purchasers of the shares of Common Stock offered hereby should
consider carefully the following investment considerations, as well as the other
information set forth or incorporated by reference in this Prospectus.
 
FLUCTUATIONS IN REFINING MARGINS
 
     The Company's operating results depend largely on the spread, or margin,
between prices paid by the market for refined petroleum products and prices paid
by the Company for crude oils and feedstocks. The Company's refining margins and
operating results have fluctuated, and will continue to fluctuate, due to
numerous factors, including changes in operating levels of other refineries in
the Company's marketing areas and in other areas of the United States, changes
in the differentials between sour and sweet crude oil prices on international
and U.S. markets, changes in the level of imported refined products and
variations in levels of demand for its principal products. Although an increase
or decrease in the price of crude oil generally results in a corresponding
increase or decrease in the price of refined products, changes in the prices of
refined products generally lag behind upward and downward changes in crude oil
prices. As a result, a rapid and significant increase in the market price for
crude oil could have an adverse impact on refining margins. The Company's future
results of operations will continue to be affected by these factors. Future
margins, results of operations and earnings per share could also be affected by
other factors beyond the Company's control, such as changes in, or the enactment
of, environmental or other regulations, which could require substantial
expenditures without necessarily increasing capacity or operating efficiency.
See "Management's Discussion and Analysis of Results of Operations and Financial
Condition" and "Business."
 
DEPENDENCE ON NAVAJO REFINERY
 
     The Company's performance depends primarily upon Navajo's results of
operations. Prolonged downtime of the Navajo Refinery for scheduled maintenance
turnarounds, unanticipated repairs or other reasons could materially and
adversely affect the Company's operating results. The Company's operations are
subject to the normal hazards and risks of refinery operations. The Company
maintains insurance, but there is no assurance that the Company will not incur
losses beyond the limits, or outside the coverage, of its insurance. See
"Business -- Insurance."
 
UNCERTAINTIES RELATED TO CAPITAL IMPROVEMENT PROJECTS
 
     The Company's ability to implement the capital improvement projects it has
identified for enhancing the Navajo Refinery will depend on several factors,
some of which will be beyond the Company's control. Among those factors will be
the absence of unanticipated technical difficulties, fabrication delays or other
occurrences, all of which could increase the cost, and delay the completion, of
these projects. In addition, the identified refinery enhancement projects will
require the Company to obtain certain governmental approvals, and there can be
no assurance whether or when the Company will obtain those permits. Because of
these uncertainties, the Company is unable to predict when these projects will
be fully implemented or to provide any assurance that the anticipated benefits
of these projects will be realized or, if realized, will not be offset by other
factors affecting the Company's operations. In addition to the foregoing,
management will have broad discretion in deciding whether to implement any of
the other capital improvement projects it is currently evaluating.
 
COMPETITION; PIPELINE CONSTRAINTS
 
     The petroleum refining business is highly competitive. Among the Company's
competitors are some of the world's largest integrated petroleum companies,
which have their own crude oil supplies, distribution and marketing systems. In
addition, Diamond Shamrock, Inc., an independent refiner and marketer, is
building a 420-mile, ten-inch refined products pipeline from its McKee refinery
near Dumas, Texas to El Paso, the Company's largest market. Diamond Shamrock has
announced that it expects to complete that pipeline, which will have an initial
capacity of 25,000 BPD, in October 1995, and that it intends to use its pipeline
to supply fuel to the El Paso, Arizona and northern Mexico markets. The Diamond
Shamrock pipeline could substantially increase the supply of products in certain
of the Company's principal markets. In addition, there is currently excess
pipeline capacity from the West Coast into the Company's Arizona markets. There
can be no assurance that West Coast refiners will not seek to increase shipments
of refined products into the Company's markets or that other industry
participants will not seek to deliver their products to the Company's
 
                                        9
<PAGE>   11
 
markets through existing pipelines, new pipelines or otherwise. An increased
supply of products in the Company's markets could adversely affect its sales
volume and the prices it can obtain for its products.
 
     At times in the past, the common carrier pipelines used by the Company to
serve the Arizona markets have been operated at or near their capacity. In
addition, the common carrier pipeline used by the Company to serve the
Albuquerque market currently is operating at or near capacity. As a result, the
volume of refined products that the Company and other shippers have been able to
deliver to these markets at times has been limited. In general, no assurances
can be given that the Company will not experience future constraints on its
ability to deliver its products through common carrier pipelines or that any
existing constraints will not worsen. In particular, the flow of additional
products into El Paso for shipment to Arizona, either as a result of the new
Diamond Shamrock pipeline or otherwise, could result in the reoccurrence of such
constraints. See "Business -- Navajo Refining Company -- Markets and
Competition."
 
SALES TO PRINCIPAL CUSTOMERS
 
     For the 1994 fiscal year, approximately 12% of the Company's revenues
resulted from sales of jet fuel to the United States government and 11% were
attributable to sales of gasoline to an affiliate of PEMEX, the government-owned
energy company of Mexico. Sales to the United States government have been made
pursuant to a series of one-year contracts and sales to PEMEX have been made
under a contract that expires in mid-1997. The loss of either or both of these
customers could have a material and adverse effect on the Company's results of
operations. See "Business -- Navajo Refining Company -- Principal Products and
Customers."
 
ENVIRONMENTAL REGULATION
 
     The Company's operations are subject to federal, state and local laws and
regulations governing, among other things, emissions to air, discharges to
water, and transportation, treatment and disposal of waste and other materials.
The Company is and has been the subject of various state, federal and private
proceedings relating to environmental regulations and conditions, including a
currently pending proceeding brought by the United States Department of Justice
(the "DOJ") on behalf of the Environmental Protection Agency (the "EPA")
alleging ongoing violations of the Resource Conservation and Recovery Act
("RCRA") at the Navajo Refinery. The Company believes that it is in the final
stages of negotiating a settlement of this litigation with the DOJ and the EPA,
which, if consummated, could involve expenditures by the Company of
approximately $3 million to $4 million to construct a new wastewater management
system and to close existing wastewater evaporation ponds. Any settlement with
the DOJ also is expected to involve the payment of a civil penalty; however,
based on the negotiations between the Company and the DOJ, the Company does not
expect the amount of the civil penalty to have a material adverse effect on its
results of operations or financial condition. There can be no assurance,
however, that the Company and the government will settle the outstanding
litigation or that, if not settled, the final resolution of that suit would not
have a material adverse effect on the Company and its results of operations or
financial condition.
 
     While the specifics cannot be presently determined, new laws or regulations
or changes in existing laws or regulations could require the Company to make
significant site or operational modifications, which could involve substantial
expenditures or the reduction or suspension of certain operations. See
"Business -- Regulation."
 
LIMITED LIQUIDITY OF COMMON STOCK
 
     Although the Common Stock is listed on the American Stock Exchange, trading
volume has frequently been low over the past several years. Approximately 45% of
the outstanding shares of Common Stock is held by or for the benefit of two
families, which have been significant stockholders of the Company for over 30
years. Approximately 15% of the outstanding shares of Common Stock is held by
the Company's Employee Stock Ownership Plan (the "ESOP"). Immediately after
giving effect to the Offering, the two principal stockholder families, which are
the Selling Stockholders in the Offering, will beneficially own, in the
aggregate, approximately 28% of the outstanding Common Stock and the ESOP will
own approximately 12% of the outstanding Common Stock. There can be no assurance
that the consummation of the Offering will result in greater trading volume in
the Common Stock. See "Price Range of Common Stock and Dividend Policy" and
"Selling Stockholders."

                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of 1,500,000 shares of Common
Stock in the Offering are estimated to be $40.4 million (assuming a sale price
to the public of $28.50 per share of Common Stock). The Company will use
approximately $15 million of the net proceeds to pay for certain identified
projects to enhance the Navajo Refinery. The Company will use its remaining net
proceeds, together with internally generated funds, for other capital
improvement projects currently being evaluated by it and/or for general
corporate purposes. Pending use, the net proceeds to the Company from the
Offering will be invested in short-term, interest-bearing securities. See
"Capital Improvement Projects."
 
     The Company will not receive any portion of the net proceeds from the sale
of the shares of Common Stock by the Selling Stockholders.
 
                          CAPITAL IMPROVEMENT PROJECTS
 
IDENTIFIED REFINERY ENHANCEMENT PROJECTS
 
     As part of its efforts to improve production efficiencies, management
intends to enhance the Navajo Refinery by upgrading the FCC and alkylation
units, constructing an isomerization unit and installing a new SHP unit. These
projects are intended to improve the Navajo Refinery's ability to produce a
greater proportion of higher yielding products, principally "premium" (high
octane) gasolines, and to enhance management's flexibility to choose among
different types of crude oils and other raw materials in response to changing
prices of supplies. The Company currently estimates that the cost of these
projects will be approximately $15 million and expects to implement them over an
18-month period.
 
     The modified FCC unit is expected to permit the refining of heavier
feedstocks than are currently processed, which would enhance the Company's
ability to take advantage of price differentials between sweet and sour crude
oils. Similarly, the isomerization unit is expected to provide the Company with
the ability to upgrade additional quantities of lower priced natural gasoline
into finished gasoline. It is anticipated that the SHP unit and the upgraded
alkylation unit will increase the refinery's production capacity for alkylate, a
high octane gasoline blendstock, which also would contribute to the refinery's
improved ability to produce premium unleaded gasolines and to upgrade natural
gasoline into a refined product. Consequently, the Company expects that the
enhancements to the Navajo Refinery will provide management with additional
flexibility in managing the refinery's crude oil and other raw materials
supplies. Further, based on industry studies concerning new environmental
regulations promulgated by the California Air Resources Board and scheduled to
go into effect in California in 1996, it appears that California refiners may
require increased supplies of alkylates to produce the cleaner burning gasolines
called for by the new regulations. In that event, the Navajo Refinery's
increased production of alkylate could be made available for sale to California
refineries.
 
     The Company expects to commence its indentified refinery enhancement
projects promptly. However, management intends to bring the new and upgraded
equipment on-line in a manner that will minimize disruption to the Navajo
Refinery's operations. Consequently, management does not expect to make the FCC
modifications until the scheduled fall 1996 maintenance turnaround of the
refinery.
 
OTHER PROJECTS UNDER CONSIDERATION
 
     The Company is currently evaluating certain other enhancements and
additions to the Navajo Refinery and the related supply and distribution systems
to better position it to respond to competitive pressures and to meet possible
increases in demand for refined products. Future capital projects that are being
considered include (i) the redistribution of process activities between the
Lovington and Artesia facilities in order to realize potential operating and
transportation cost savings, (ii) other upgrades to improve the efficiency of
the Navajo Refinery, (iii) modifications to increase product pipeline
distribution capacity and (iv) product pipeline reconditioning and construction
to facilitate entry into new markets. Management believes that the proceeds from
the Offering not expended on the currently identified projects, together with
cash flows from operating activities, should be sufficient to fund other
projects under consideration.

     As of April 30, 1995, the Company had approximately 2,100 stockholders of
record.
 
     The Company, which currently pays a quarterly dividend of $.10 per share of
Common Stock outstanding, considers the declaration of dividends on a quarterly
basis. The Company's ability to pay future dividends depends on its future
earnings and capital requirements, and on its financial condition and other
factors. The Company's senior notes (the "Senior Notes") and its revolving
credit agreement (the "Credit Agreement") could limit the Company's ability to
pay dividends under certain circumstances. See Note 6 to the Consolidated
Financial Statements for the year ended July 31, 1994 included elsewhere herein.

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS
                     OF OPERATIONS AND FINANCIAL CONDITION
 
OVERVIEW
 
     The Company's operating results depend largely on the spread, or margin,
between prices paid by the market for refined petroleum products and prices paid
by the Company for crude oils and feedstocks. The Company's refining margins and
operating results have fluctuated, and will continue to fluctuate, due to
numerous factors, including changes in operating levels of other refineries in
the Company's marketing areas and in other areas of the United States, changes
in the differentials between sour and sweet crude oil prices on international
and U.S. markets, changes in the level of imported refined products and
variations in levels of demand for its principal products. Although an increase
or decrease in the price of crude oil generally results in a corresponding
increase or decrease in the price of refined products, changes in the prices of
refined products generally lag behind upward and downward changes in crude oil
prices. As a result, a rapid and significant increase in the market price for
crude oil could have an adverse impact on refining margins. The Company's future
results of operations will continue to be affected by these factors. Future
margins, results of operations and earnings per share could also be affected by
other factors beyond the Company's control, such as changes in, or the enactment
of, environmental or other regulations, which could require substantial
expenditures without necessarily increasing capacity or operating efficiency.
 
     The Company's results of operations experience some seasonal fluctuations,
with demand for gasoline and asphalt products historically being stronger from
March through October, which are the key "driving" and road construction months,
than during the rest of the year. In addition, the Company's refineries are
subject to preventive maintenance turnarounds scheduled at two- or three-year
intervals, during which all or a portion of the facilities are shut down. As a
result, the Company's operating results during the periods and full fiscal years
when turnarounds occur typically will be below the Company's results for the
comparable prior year periods. In addition, in part because the Navajo and
Montana Refineries serve markets with different supply and demand relationships,
the refineries' operating results do not always increase or decrease in tandem.
Consequently, there have been periods (such as fiscal 1994 and 1993) when MRC's
results of operations have contributed more to the Company's overall results of
operations than management ordinarily would expect given the relative size of
the Navajo and Montana Refineries.
 
RESULTS OF OPERATIONS
 
  Six Months ended January 31, 1995 Versus Six Months ended January 31, 1994
 
     For the six months ended January 31, 1995, net income was $13.9 million,
which included a $5.7 million contribution in the first quarter from the
cumulative effect of a change in accounting for turnarounds relating to prior
periods, compared to $12.5 million for the same period of fiscal 1994. Effective
August 1, 1994, the Company changed its method of accounting for turnaround
costs. Turnarounds consist of preventive maintenance on major processing units
as well as the shutdown and restart of all units, and generally are scheduled at
two- to three-year intervals. Previously, the Company estimated the costs of the
next scheduled turnaround and ratably accrued the related expenses prior to the
actual turnaround. To provide for a better matching of turnaround costs with
revenues, the Company changed its accounting method for turnaround costs to one
that results in the amortization of costs incurred over the period until the
next scheduled turnaround. The amortization of turnaround costs is recorded in
depreciation, depletion and amortization expense, whereas previously the
expenses accrued prior to the turnaround were recorded in cost of sales as an
operating expense. The increase in the current year in depreciation expense is
primarily the result of this change in accounting. The cumulative effect of this
accounting change was to increase net income in the current year by $5.7
million. Excluding the cumulative effect of the accounting change, the new
method of accounting for turnaround costs increased net income for the first
half of fiscal 1995 by $1.0 million to $8.2 million. If the accounting change
for turnaround costs had been retroactively applied, pro forma net income for
the six months ended January 31, 1994 would have increased by $1.1 million to
$13.6 million and pro forma net income for the full 1994 fiscal year would have
increased by $1.3 million to $22.0 million.
 
                                       16
<PAGE>   18
 
     Excluding the effects of the change in accounting for turnarounds, the $4.3
million decrease in net income for the first half of 1995 compared to the prior
year period is due primarily to a 22% reduction in gross margins per barrel,
offset partially by a 15% increase in volumes sold. Gross margins for the
current year were less than in the comparable prior year period because crude
oil costs per barrel increased at a 15% rate over the prior year, while product
prices per barrel increased at only a 4% rate. Gross margins per barrel at the
Montana Refinery, particularly in the latter part of the second quarter of 1995,
were 30% below the comparable prior year period because product prices per
barrel increased 1% over the prior year levels while crude oil costs per barrel
increased 23%. Revenues for the six months ended January 31, 1995 were 20%
higher than in the comparable prior year period due to a 15% increase in sales
volumes in the current year period and 4% higher product prices per barrel in
the first half of 1995 compared to the 1994 period. The prior year's sales
volumes were adversely affected by the scheduled maintenance turnaround at the
Navajo Refinery from September to November 1993.
 
  1994 Versus 1993
 
     Net income for the year ended July 31, 1994 was $20.7 million compared to
$19.9 million before an accounting change in the 1993 fiscal year. In the 1993
fiscal year, the Company adopted Statement of Financial Accounting Standards No.
109, "Accounting for Income Taxes" ("SFAS 109"), which amended the accounting
for income taxes from the deferral method to the liability method. The
cumulative effect of this change in accounting was to decrease net income by
$1.0 million to $19.0 million for the year ended July 31, 1993. Other than the
cumulative effect of the adjustment, the effect of the change on income for the
year ended July 31, 1993 was not material.
 
     While gross margins per barrel for the 1994 fiscal year as a whole improved
11% over the levels of the prior year, the 1994 year's margins per barrel were
adversely affected by Navajo's refined product margins per barrel in the fourth
quarter of 1994, which decreased 43% from the same period during 1993 because
product prices per barrel fell 9% in the fourth quarter of 1994 while crude oil
cost per barrel rose 3% in the same period. MRC had a third consecutive record
earnings year in fiscal 1994 because its gross margins were positively affected
by favorable prices for crude oil and other feedstocks. Notwithstanding the
Company's higher gross margins, as a whole, for 1994 compared to 1993, net sales
for the 1994 fiscal year decreased 13% from the prior year's levels as the
result of a 10% decrease in product prices per barrel and a 3% decline in sales
volume for the year caused primarily by a scheduled major maintenance turnaround
of the Navajo Refinery. Under the prior accounting method, a charge of $2.9
million was recorded in the fourth quarter of fiscal 1993 to reflect an increase
in the estimate for the costs to be incurred in the turnaround, and an
additional $1.5 million in excess of the revised accrual at July 31, 1993 was
included as an expense with respect to the scheduled turnaround in the 1994
year's second quarter. Increases in other operating expense and in exploration
expenses, including dry holes, further reduced income in 1994.
 
     Pre-tax income in 1993 was improved by $4 million relating to the
settlement of litigation with a common carrier pipeline and was reduced by a $2
million charge relating to an enforcement action brought by the DOJ alleging
that Navajo, beginning in September 1990 and continuing until the present,
violated and continues to violate the Resource Conservation and Recovery Act
(RCRA) and implementing regulations by treating, storing and disposing of
certain hazardous wastes without required authorization and without compliance
with regulatory requirements. See "Financial Condition" below.
 
  1993 Versus 1992
 
     Net income for the year ended July 31, 1993 was $19.9 million before a $1.0
million accounting change related to the adoption of SFAS 109 as discussed
above, compared to $2.8 million in the prior year.
 
     Net income for the year ended July 31, 1993 improved substantially over the
prior year due to 20% and 22% increases in gross margins per barrel and sales
volumes, respectively. The increase in sales volume over the prior year resulted
from higher throughputs made possible by the refinery expansion completed in
December 1991 and the alleviation of product pipeline distribution constraints
in October 1992. Gross margins and sales volumes for the 1993 fiscal year also
may have been favorably affected by a temporary suspension of
 
                                       17
<PAGE>   19
 
production during most of the year by a refinery in the Company's principal
market area. In addition, MRC experienced a second consecutive record earnings
year in fiscal 1993. Profitability in fiscal 1993 was reduced due to increases
in operating expenses, principally resulting from a charge taken in the fourth
quarter of $2.9 million to increase the estimate for the planned fall 1993 major
maintenance turnaround and increases in general and administrative expense and
depreciation, depletion and amortization expense, primarily attributable to the
refinery expansion. Net income in the fourth quarter of the 1993 fiscal year was
improved by pretax income of $4 million relating to a settlement of litigation
with a common carrier pipeline company and the $2 million pre-tax charge
established in connection with the DOJ litigation.
 
     Net income in the fourth quarter of fiscal 1992 was improved by the
elimination, as a consequence of the Company's acquisition of the remaining
interest in MRC, of a $2.6 million liability for deferred taxes that had been
reflected on the Company's financial statements.
 
FINANCIAL CONDITION
 
     Cash flows from operations during the six months ended January 31, 1995
exceeded capital expenditures and dividends paid, resulting in a net increase in
cash and cash equivalents of $9.7 million. Cash flows from operations for fiscal
1994 were slightly less than capital expenditures, debt payments and dividends
paid, resulting in a net decrease in cash and cash equivalents of $3.3 million.
Working capital increased during the first half of 1995 by $10.2 million to
$28.4 million at January 31, 1995. The Company's long-term debt represented
49.0% of total capitalization at January 31, 1995 compared to 53.5% at July 31,
1994. At January 31, 1995, the Company had $25 million of borrowing capacity
under the Credit Agreement, which is available for short term working capital
needs. The Company believes that these sources of funds, together with future
cash flows from operations and the estimated net proceeds from the sale of
1,500,000 shares of Common Stock offered hereby, should provide sufficient
resources, financial strength and flexibility for the Company to satisfy its
liquidity needs, capital requirements (including requirements related to the
identified refinery enhancement projects for the Navajo Refinery) and debt
service obligations and to permit the payment of dividends for the foreseeable
future.
 
     Net cash provided by operating activities amounted to $18.0 million in the
first six months of fiscal 1995, compared to $13.1 million in the same period of
the prior year. The principal reason for the increase in cash provided from
operations was changes in working capital accounts; this factor was partially
offset by the reduction in income before the accounting change. The change in
the method of accounting for turnaround costs had no effect on cash provided
from operations. Net cash provided by operating activities amounted to $27.7
million in fiscal 1994, compared to $38.7 million in fiscal 1993 and $1.0
million in fiscal 1992. The primary reason for the differences in cash provided
from operations during the three years ended July 31, 1994 was differences in
earnings, which were $20.7 million in fiscal 1994, $19.0 million in fiscal 1993
and $2.8 million in fiscal 1992. Additionally, significant amounts of funds were
required in both fiscal 1994 and fiscal 1992 to maintain working capital
accounts compared to the 1993 fiscal year.
 
     Cash flows used for investing activities (consisting solely of capital
expenditures) were $6.6 million in the first six months of fiscal 1995, compared
to $13.0 million in the same period of the prior year. Cash flows used for
investing activities totalled $65.7 million over the last three full fiscal
years, $22.5 million in 1994, $20.1 million in 1993 and $23.1 million in 1992,
principally for capital expenditures. The expenditures in 1992 were primarily
for the final phases of the expansion of the Navajo Refinery's crude capacity
from 40,000 to 60,000 BPD. This expansion included the installation of a new
continuous catalytic regeneration reformer, the modification of the fluid
catalytic cracker, the expansion of the naphtha desulfurizer and the
installation of a new sulphur plant and alkylation unit. In fiscal 1993 and
1994, most of the funds expended were for refinery projects including diesel
desulfurization units at the Navajo and Montana Refineries in order to meet the
October 1993 requirements for lower sulphur content in diesel fuel. The Navajo
Refinery unit was completed in August 1993 and the Montana Refinery unit was
completed in December 1993.
 
     The Company plans to use approximately $15 million of its net proceeds from
this Offering to pay for the identified capital improvement projects to enhance
the Navajo Refinery described under "Capital Improvements Projects -- Identified
Refinery Enhancement Projects." Management believes that the proceeds from
 
                                       18
<PAGE>   20
 
the Offering not expended on the currently identified projects, together with
cash flows from operating activities, should be sufficient to fund other
projects under consideration. Excluding the capital improvement projects
described under "Capital Improvements Projects," the Company has a $15 million
capital budget for fiscal 1995, of which $11 million is for refinery projects
with the remaining $4 million for oil and gas exploration. Although there can
be no assurances, management considers the planned maintenance expenditures for
1995 of approximately $8 million to be indicative of the level of capital
spending that will be necessary to maintain the Company's operations in the
future. The majority of the oil and gas budget will be used to fund the
anticipated costs of completion of production facilities for two offshore
properties in which the Company has an interest. Although the Company's capital
expenditures budget contemplates capitalizable costs associated with compliance
with environmental regulations, the regulations implementing recent amendments
to the Clean Air Act could have a substantial impact on the Company's future
capital spending requirements. Final regulations implementing these amendments
have not yet been promulgated; therefore the costs of complying with these
regulations are not yet determinable by the Company. In addition, the Company
is unable to predict the impact that new environmental rules and regulations or
changes in interpretations of existing laws and regulations might have on its
capital spending needs.
 
     Cash flows used for financing activities amounted to $1.7 million in the
first six months of fiscal 1995, compared to $1.2 million in the same period of
the prior year; substantially all these amounts were for dividends. The next
principal payment of $5.6 million on the Company's Senior Notes is due in June
1995. Cash flows used for financing activities amounted to $8.5 million and
$13.4 million in fiscal 1994 and 1993, respectively, compared to cash flows
provided by financing activities of $6.3 million in fiscal 1992. Financing
activities over the last three years included the renewal of the Company's
Credit Agreement in July 1993, which provides for a total facility of $100
million, the full amount of which may be used to support letters of credit and
$25 million of which may be used for direct borrowings for short-term working
capital needs. The Company had $10.5 million of borrowings outstanding under its
Credit Agreement as of July 31, 1992, the full amount of which was repaid during
fiscal 1993. The Company's Credit Agreement will expire August 1, 1995; however,
the Company expects to renew the Credit Agreement on substantially the same
terms. The
Company's first principal payment of $5.6 million on the Senior Notes was made
in June 1994. See Note 6 to the Consolidated Financial Statements for the year
ended July 31, 1994 included elsewhere herein for a summary of the terms of the
Senior Notes and the Credit Agreement, which could restrict the Company's
ability to pay dividends under certain circumstances.
 
     Diamond Shamrock, Inc., an independent refiner and marketer, is building a
420-mile, ten-inch refined products pipeline from its McKee refinery near Dumas,
Texas to El Paso, the Company's largest market. Diamond Shamrock has announced
that it expects to complete that pipeline, which will have an initial capacity
of 25,000 BPD, in October 1995, and that it intends to use its pipeline to
supply fuel to the El Paso, Arizona and northern Mexico markets. The Diamond
Shamrock pipeline could substantially increase the supply of products in the
Company's principal markets. At times in the past, the common carrier pipelines
used by the Company to serve the Tucson and Phoenix markets have been operated
at or near their capacity. In addition, the common carrier pipeline used by the
Company to serve the Albuquerque market currently is operating at or near
capacity. As a result, the volume of refined products that the Company and other
shippers have been able to deliver to these markets at times has been limited.
In general, there is no assurance that the Company will not experience future
constraints on its ability to deliver its products through common carrier
pipelines or that any existing constraints will not worsen. In particular, the
flow of additional product into El Paso for shipment to Arizona, either as a
result of the new Diamond Shamrock pipeline or otherwise, could result in the
reoccurrence of such constraints. See "Business -- Navajo Refining
Company -- Markets and Competition."
 
     In July 1993, the DOJ filed suit against Navajo alleging that, beginning in
September 1990 and continuing through the present, Navajo has violated and
continues to violate RCRA and implementing regulations of the EPA by treating,
storing and disposing of certain hazardous wastes without compliance with
regulatory requirements. The Company believes that the parties are in the final
stage of negotiations that should resolve some, if not all, of the litigation.
Based on those negotiations, the Company would close the existing evaporation
ponds of its wastewater management system, at a cost of approximately $1 million
to be expended over a several year period. The negotiations also contemplate
that the Company would implement
 
                                       19
<PAGE>   21
 
one of several alternatives to the existing wastewater treatment system.
Depending upon which approach is utilized, the Company could incur total costs
of approximately $3 million over the next several years. The costs to implement
an alternative wastewater treatment system would be capitalized and amortized
over the future useful life of the resulting asset in accordance with generally
accepted accounting principles. Any settlement with the DOJ also is expected to
involve the payment of a civil penalty, which, based on negotiations among the
Company, the EPA and the DOJ, the Company does not believe will have a material
adverse effect on its financial position or results of operations. In fiscal
1993, the Company recorded a $2 million reserve for the litigation, principally
to provide for the cost of closing the existing ponds. See "Investment
Considerations -- Environmental Regulation."

                                    BUSINESS
OVERVIEW
 
     The Company is an independent refiner of petroleum and petroleum
derivatives and produces high value light products such as gasoline, diesel fuel
and jet fuel for sale primarily in the southwestern United States and northern
Mexico. The Company owns a high-conversion petroleum refinery in Artesia, New
Mexico, which it operates in conjunction with crude, vacuum distillation and
other facilities situated 65 miles away in Lovington, New Mexico. The Navajo
Refinery has a crude capacity of 60,000 BPD and can process a variety of high
sulphur sour crude oils. For the last three fiscal years, sour crude oils have
represented approximately 85% of the crude oils processed by the Navajo
Refinery. The Navajo Refinery's processing capabilities enable management to
vary its crude supply mix to take advantage of changes in raw materials prices
and to respond to fluctuations in the availability of crude oil supplies. The
Navajo Refinery converts approximately 86% of its raw materials throughput into
high value light products. For fiscal 1994, including barrels purchased for
resale, gasoline, diesel fuel and jet fuel represented 56.5%, 19.7% and 11.1%,
respectively, of Navajo's sales volume. For the last three fiscal years,
excluding downtime for scheduled maintenance and turnarounds, the Navajo
Refinery has operated at an average annual crude capacity utilization rate of
approximately 93%.
 
     The Artesia facility is located on a 300-acre site and has fully integrated
crude, FCC, vacuum distillation, alkylation, hydrodesulfurization and reforming
units, and approximately 1.5 million barrels of feedstock and product tank
storage. The Lovington facility is operated as an integrated component of the
Navajo Refinery and refines crude oil into intermediate products, which are
transported, primarily via a Company-owned pipeline, to the Artesia facility for
further processing. Navajo's assets also include a 500-mile crude oil gathering
pipeline system, 30 crude oil and product tank trucks, three refined products
pipelines and product storage at terminals in Tucson, Albuquerque, Artesia and
El Paso in which the Company has 50% or greater interests.
 
     The Company also owns a 7,000 BPD petroleum refinery near Great Falls,
Montana, which can process a range of crude oils and which serves primarily the
State of Montana. For fiscal 1994, including barrels purchased for resale,
gasoline, diesel fuel, asphalt and jet fuels, represented 38.6%, 24.3%, 18.6%
and 15.7% of MRC's sales volume. For the last three fiscal years, excluding
downtime for scheduled maintenance and turnarounds, the Montana Refinery has
operated at an average annual crude capacity utilization rate of approximately
94%.
 
     In addition to its refining operations, the Company also conducts a
small-scale oil and gas exploration and production program.
 
BUSINESS STRENGTHS
 
     Despite fluctuating industry conditions, the Company, which was
incorporated in 1947 and acquired the Navajo Refinery in 1969, has generated
positive net income and cash flow from operations for each of the past 24 years.
The Company had net income and cash from operating activities of $24.0 million
and $33.6 million, respectively, for fiscal 1990, $11.7 million and $27.9
million for fiscal 1991, $2.8 million and $1.0 million for fiscal 1992, $19.0
million and $38.7 million for fiscal 1993, and $20.7 million and $27.7 million
for fiscal 1994. The Company believes that it has certain business strengths
that have contributed to its history of profitable operations. Among those
strengths are the following:
 
     - Geographic location/attractive markets. The Navajo Refinery primarily
      serves the growing southwestern United States market, including El Paso,
      Albuquerque, Phoenix and Tucson, which generally has favorable supply and
      demand characteristics compared to Gulf Coast markets, and the northern
      Mexico market, which is expected to experience demand growth over the next
      several years. According to data compiled by the United States Bureau of
      the Census, from April 1, 1990 to July 1, 1993, the population of the
      Navajo Refinery's principal market area in the U.S. (Arizona, New Mexico
      and El Paso) grew at a compound annual rate of 2.2%, compared to a
      nationwide compound annual growth rate of 1.1% during that period. From
      April 1, 1980 to July 1, 1993, this area grew at a compound annual rate of
      2.5%, compared to a nationwide rate of 1.0%. The Montana Refinery serves
      primarily the
 
                                       21
<PAGE>   23
 
      State of Montana, which also historically has had relatively favorable
      supply and demand characteristics.
 
     - High conversion refinery. The Navajo Refinery converts approximately 86%
      of its raw materials throughput into high value light products from a
      variety of sour crudes and can vary the refined products it produces to
      respond to fluctuations in demand. The Navajo Refinery's processing
      facilities also enable management to vary the refinery's crude supply mix
      to take advantage of changes in raw materials prices and to respond to
      fluctuations in the availability of crude oil supplies. For the last three
      fiscal years, sour crude oils have represented approximately 85% of the
      crude oils processed by the Navajo Refinery.
 
     - Raw material supply. Located on the northwestern shelf of the Permian
      Basin, the Navajo Refinery has direct access to a historically reliable
      crude oil supply, which is transported to the refinery primarily through a
      500-mile, Company-owned crude oil pipeline gathering system and by crude
      oil tank trucks. The Company's crude oil pipelines connect to tankage
      facilities in New Mexico and Texas, and are connected to, or are located
      in proximity to, a number of common carrier crude oil pipelines. The
      Montana Refinery obtains most of its crude oil via a 93-mile,
      Company-owned pipeline which runs from near the Canadian border.
 
     - Distribution logistics. The Company distributes refined products from the
      Navajo Refinery to its principal markets primarily through (i) a
      Company-owned pipeline extending from Artesia to El Paso and (ii) a
      Company-owned pipeline extending from Artesia to Orla, Texas, and from
      there west to El Paso. Products can be shipped by pipeline from El Paso to
      Albuquerque via a products pipeline system owned by Chevron Pipeline
      Company and to Tucson and Phoenix via a products pipeline system owned by
      Santa Fe Pacific Pipeline. The Company also owns a segment of a products
      pipeline running from Orla to Odessa, Texas, which is currently inactive.
      The Company believes that the proximity of the Navajo Refinery to its
      principal markets and the refinery's products distribution network provide
      a transportation cost advantage over Gulf Coast and West Coast refineries
      in supplying its markets.
 
BUSINESS STRATEGY
 
     The Company's strategy has been, and continues to be, to optimize its
refinery operations to increase the proportion of high value products it
produces and to lower operating costs. As part of this strategy, the Company
completed a $63 million expansion of the Navajo Refinery in December 1991,
which, among other things, increased its refining capacity from 40,000 to 60,000
BPD. That expansion consisted principally of the addition of a new continuous
catalytic regeneration unit, the modification of the FCC unit, the expansion of
the naphtha desulfurizer and the installation of new sulphur and alkylation
units. The installation of new equipment and the modification and upgrading of
existing equipment as part of that expansion program increased the proportion of
sour crude oils that the Navajo Refinery can process and increased the
proportion of its throughput that can be converted into higher value products.
 
     The Company continues to evaluate improvements to its operating cost
structure, refineries and crude oil gathering and product distribution systems.
Management believes that certain enhancements and additions to the Navajo
Refinery should better position the Company to respond to competitive pressures
and to meet possible increases in demand for refined products. As part of its
strategy, management intends to spend approximately $15 million over an 18-month
period on identified capital enhancement projects at the Navajo Refinery. Those
projects involve upgrades to the FCC and alkylation units, the construction of
an isomerization unit and the installation of a new SHP unit. Management expects
these projects to increase the Navajo Refinery's total gasoline production and
to improve its ability to produce a greater proportion of "premium" (high
octane) gasoline. In addition, these enhancements and plant additions are
expected to improve management's flexibility to operate using different types of
crude oils and other raw materials and to provide a platform for further
refinery expansion, if appropriate, in the future. In addition, the Company is
evaluating a number of other possible capital improvement projects, including
(i) the redistribution of process activities between the Lovington and Artesia
facilities in order to realize potential operating and transportation cost
savings, (ii) other upgrades to improve the efficiency of the Navajo Refinery,
(iii) modifications to increase
 
                                       22

product pipeline distribution capacity and (iv) product pipeline reconditioning
and construction to facilitate entry into new markets. See "Capital Improvement
Projects -- Other Projects Under Consideration."
 
NAVAJO REFINING COMPANY
 
  Facilities
 
     With the completion of a major expansion in December 1991, Navajo's
refining capacity increased from 40,000 to 60,000 BPD. The Navajo Refinery has
the ability to process a variety of sour crude oils and, as a result of the
expansion, has increased the proportion of throughput that can be converted into
high value light products (such as gasoline, diesel fuel and jet fuel). The
expansion has also increased internal high octane capabilities and has augmented
overall operating flexibility.

     The Company's 500 miles of crude gathering pipelines lead to the Artesia
and Lovington facilities from various points in southeastern New Mexico. The
Company distributes refined products from the Navajo Refinery to its principal
markets primarily through (i) a Company-owned pipeline which extends from
Artesia to El Paso and (ii) a Company owned pipeline extending from Artesia to
Orla, Texas and from there west to El Paso. The Company has product storage at
terminals in Tucson, Albuquerque, Artesia and El Paso in which the Company has
50% or greater interests. The Company also owns a segment of products pipeline
running from Orla to Odessa, Texas, which is currently inactive. The Odessa
pipeline segment could be utilized following certain capital expenditures for
reconditioning.
 
  Markets and Competition
 
     The Navajo Refinery primarily serves the growing southwestern United States
market, including El Paso, Albuquerque, Phoenix and Tucson, and the northern
Mexico market. The Company's products are shipped by pipeline from El Paso to
Albuquerque via a products pipeline system owned by Chevron Pipeline Company and
to Tucson and Phoenix via a products pipeline system owned by Santa Fe Pacific
Pipeline. The map below illustrates the Company's distribution system to its
major markets. Access to the Company's markets by Gulf Coast refiners is limited
primarily by the lack of available products pipelines.

     The petroleum refining business is highly competitive. Among the Company's
competitors are some of the world's largest integrated petroleum companies,
which have their own crude oil supplies, distribution and marketing systems. The
Company competes with independent refiners as well. Competition in particular
geographic markets is affected primarily by the amounts of refined products
produced by refineries located in such markets and by the availability of
refined products and the cost of transportation to such markets from refineries
located outside those markets. Diamond Shamrock, Inc., an independent refiner
and marketer, is building a 420-mile, ten-inch refined products pipeline from
its McKee refinery near Dumas, Texas to El Paso, the Company's largest market.
Diamond Shamrock has announced that it expects to complete that pipeline, which
will have an initial capacity of 25,000 BPD, in October 1995, and that it
intends to use its pipeline to supply fuel to the El Paso, Arizona and northern
Mexico markets. The Diamond Shamrock pipeline could substantially increase the
supply of refined products in the Company's principal markets. In addition,
there is excess pipeline capacity from the West Coast into the Company's Arizona
markets. There can be no assurance that West Coast refiners will not seek to
increase shipments of refined products into the Company's markets or that other
industry participants will not seek to deliver their products to the Company's
markets through existing pipelines, new pipelines or otherwise. An increased
supply of products in the Company's markets could adversely affect its sales
volume and the prices it can obtain for its products.
 
     At times in the past, the common carrier pipelines used by the Company to
serve the Arizona markets have been operated at or near their capacity and have
been subject to periods of proration. In July 1993, the Company entered into a
settlement agreement regarding that pipeline system. Under the agreement, the
occurrence of certain defined events will require increases in the capacity of
the pipeline. It is anticipated that this settlement lessens, at least in the
foreseeable future, the likelihood of prolonged future constraints on the
movement of the Company's products into Arizona. In addition, the common carrier
pipeline used by the Company to serve the Albuquerque market currently is
operating at or near capacity. As a result, the volume of refined products that
the Company and other shippers have been able to deliver to these markets at
times has been limited. In general, no assurances can be given that the Company
will not experience future constraints on its ability to deliver its products
through common carrier pipelines or that any existing constraints will not
worsen. In particular, the flow of additional product into El Paso for shipment
to Arizona, either as a result of the new Diamond Shamrock pipeline or
otherwise, could result in the reoccurrence of such constraints.

  Crude Oil and Feedstock Supplies
 
     The Navajo Refinery is situated near the Permian Basin in an area with
historically abundant crude supplies. The Company purchases crude oil from
producers in nearby southeastern New Mexico and west Texas, from major oil
companies and on the spot market. Crude oil is gathered through the Company's
pipelines and tank trucks and through third party crude oil pipeline systems.
Crude oil acquired in locations distant from the refinery is exchanged for crude
oil that is transportable to the refinery. In 1993, the Company reactivated a
subsidiary, Navajo Crude Oil Marketing Company, to facilitate the purchase of
crude oil from leases in west Texas and New Mexico.
 
  Principal Products and Customers
 
     The Navajo Refinery converts approximately 86% of its raw materials
throughput into high value light products. Set forth below is certain
information regarding the principal products of Navajo during the last five
fiscal years and during the six-month periods ending January 31, 1994 and 1995:

    4.0%, 3.2%, 0.4%, 0.5% and 0.2%, respectively, of total sales volume for the
    periods shown in the table above.
 
     Light products are shipped by product pipelines or are made available at
distant points by exchanges with others. Light products are also available to
customers through truck loading facilities at the refineries and at terminals.
The demand for the Company's gasoline and asphalt products has historically been
stronger from March through October, which are the peak "driving" and road
construction months, than during the rest of the year.
 
     The Company's principal customers for gasoline include other refiners,
convenience store chains, independent marketers, an affiliate of PEMEX (the
government-owned energy company of Mexico) and retailers. Navajo's gasoline is
marketed in the southwestern United States, including the metropolitan areas of
El Paso, Phoenix, Albuquerque, and Tucson, and in portions of northern Mexico.
Diesel fuel is sold to other refiners, wholesalers, independent dealers and
railroads. Jet fuel is sold primarily for military use. Military jet fuel is
sold to the Defense Fuel Supply Center (the "DFSC") of the Defense Logistics
Agency under a series of one-year contracts that can vary significantly from
year to year. Navajo sold approximately 7,000 BPD of jet fuel to the DFSC in its
1994 fiscal year and has a contract to supply 8,100 BPD to the DFSC for the year
ending September 30, 1995. Asphalt is sold to contractors and government
authorities for highway construction and maintenance. Carbon black oil is sold
for further processing, and LPGs are sold to petrochemical plants and are used
as fuel in refinery operations.
 
     Approximately 12% of the Company's revenues for the first half of fiscal
1995 and 12% of revenues for fiscal 1994 resulted from the sale of military jet
fuel to the United States government. Although there can be no assurance that
the Company will be awarded such contracts in the future, the Company has had a
supply contract with the United States government for each of the last 26 years.
Approximately 8% of the Company's revenues for the first half of fiscal 1995 and
11% of revenues for fiscal 1994 resulted from the sale of gasoline to an
affiliate of PEMEX. Those sales were made under a contract that expires in
mid-1997. The loss of the

Company's supply contract with the United States government or with PEMEX could
have a material adverse effect on the Company's results of operations.
 
CAPITAL IMPROVEMENT PROJECTS
 
  Identified Refinery Enhancement Projects
 
     As part of its efforts to improve operating efficiencies, management
intends to enhance the Navajo Refinery by upgrading the alkylation and FCC
units, constructing an isomerization unit and installing a new SHP unit. These
projects are intended to improve the Navajo Refinery's ability to produce a
greater proportion of higher yielding products, principally "premium" (high
octane) gasolines, and to enhance management's flexibility to choose among
different types of crude oils and other raw materials in response to changing
prices of supplies. The Company currently estimates that the cost of these
projects will be approximately $15 million and expects to implement them over an
18-month period.
 
     The modified FCC unit is expected to permit the refining of heavier
feedstocks than are currently processed, which would enhance the Company's
ability to take advantage of price differentials between sweet and sour crude
oils. Similarly, the isomerization unit is expected to provide the Company with
the ability to upgrade additional quantities of lower priced natural gasoline
into finished gasoline. It is anticipated that the SHP unit and the upgraded
alkylation unit will increase the refinery's production capacity for alkylate, a
high octane gasoline blendstock, which also would contribute to the refinery's
improved ability to produce premium unleaded gasolines and to upgrade natural
gasoline into a refined product. Consequently, the Company expects that the
enhancements to the Navajo Refinery will provide management with additional
flexibility in managing the refinery's crude oil and other raw materials
supplies. Further, based on industry studies concerning new environmental
regulations promulgated by the California Air Resources Board and scheduled to
go into effect in California in 1996, it appears that California refiners may
require increased supplies of alkylates to produce the cleaner burning gasolines
called for by the new regulations. In that event, the Navajo Refinery's
increased production of alkylate could be made available for sale to California
refineries.
 
     The Company expects to commence its identified refinery enhancement
projects promptly. However, management intends to bring the new and upgraded
equipment on-line in a manner that will minimize disruption to the Navajo
Refinery's operations. Consequently, management does not expect to make the FCC
modifications until the scheduled fall 1996 maintenance turnaround of the
refinery.
 
  Other Capital Projects
 
     The Company is currently evaluating certain other enhancements and
additions to the Navajo Refinery and the related supply and distribution systems
to better position it to respond to competitive pressures and to meet possible
increases in demand for refined products. Future capital projects that are being
considered include (i) the redistribution of process activities between the
Lovington and Artesia facilities in order to realize potential operating and
transportation cost savings, (ii) other upgrades to improve the efficiency of
the Navajo Refinery, (iii) modifications to increase product pipeline
distribution capacity and (iv) product pipeline reconditioning and construction
to facilitate entry into new markets. Management believes that the proceeds from
the Offerings not expended on the currently identified projects, together with
cash flows from operating activities, should be sufficient to fund the other
projects under consideration.
 
MONTANA REFINING COMPANY
 
     MRC owns a 7,000 BPD petroleum refinery near Great Falls, Montana, which
can process a range of crude oils and which serves primarily the State of
Montana. For the last three fiscal years, excluding downtime for scheduled
maintenance and turnarounds, the Montana Refinery has operated at an average
annual crude capacity utilization rate of approximately 94%.

     The Montana Refinery obtains its supply of crude oils primarily from
suppliers in Canada via a 93-mile, Company-owned pipeline, which runs from near
the Canadian border. The Montana Refinery's principal markets include Great
Falls, Helena, Bozeman and Billings, Montana. MRC competes principally with
three other Montana refineries.
 
JET FUEL TERMINAL
 
     The Company owns and operates a 120,000 barrel capacity jet fuel terminal
near Mountain Home, Idaho, which serves as a terminalling facility for jet fuel
sold by unaffiliated producers to the Mountain Home United States Air Force
Base.
 
NAVAJO WESTERN ASPHALT COMPANY
 
     Navajo Western Asphalt Company, a wholly-owned subsidiary of the Company,
operates an asphalt marketing facility near Phoenix. The Company has recently
completed construction of asphalt processing and storage facilities that should
allow it to expand this operation. In addition to serving as a marketing outlet
for asphalt produced by Navajo at the Lovington facility, Navajo Western markets
asphalt for third parties.
 
EXPLORATION AND PRODUCTION
 
     The Company contracts with two independent oil and gas consulting groups
that identify oil and gas exploration and production projects for the Company.
The scope of this activity is presently modest relative to the Company's
refining operations. For fiscal 1995, the Company has budgeted approximately $4
million for capital expenditures related to oil and gas exploration activities.
The majority of that budget will be used to fund the anticipated costs to
complete production facilities at two offshore properties in which the Company
has an interest.
 
EMPLOYEES AND LABOR RELATIONS
 
     As of April 30, 1995, the Company had approximately 540 employees, of whom
451 were employed by the Navajo Refinery and 73 were employed at the Montana
Refinery. Of its employees, 216 are covered by collective bargaining agreements
("covered employees"). Contracts relating to the covered employees at all
facilities were negotiated during 1993 and will expire in 1996. The Company
considers its employee relations to be good.

REGULATION
 
     Refinery operations are subject to federal, state and local laws regulating
the discharge of matter into the environment or otherwise relating to the
protection of the environment. Over the years, there have been and continue to
be ongoing communications, including notices of violations, and discussions
about environmental matters, between the Company and federal and state
authorities, some of which have resulted in changes in operating procedures and
certain capital expenditures by the Company. Compliance with applicable
environmental laws and regulations will continue to have an impact on the
Company's operations and capital requirements. For example, the final form of
the regulations implementing recent amendments to the Clean Air Act could have a
substantial impact on the future capital spending requirements of the Company
and the refining industry as a whole.
 
     The EPA has promulgated regulations which substantially reduced the
allowable sulfur content of diesel fuel for sales starting in October 1993. In
fiscal 1994, the Company completed projects which allow Navajo and MRC to meet
this new standard.
 
     Effective January 1, 1995, certain cities in the country were required to
use only reformulated gasoline ("RFG"), a cleaner burning fuel. While none of
the Company's principal markets presently require RFG, this requirement could be
implemented over time. Further, other requirements of the Clean Air Act could
cause the Company to be required to expend substantial amounts for compliance at
its refineries. Expenditures in connection with Clean Air Act at the Montana
Refinery could be proportionally larger than similar expenditures anticipated
for the Navajo Refinery. However, the specifics of these requirements and their
attendant costs are not presently determinable.
 
     The Company is and has been the subject of various state, federal and
private proceedings relating to environmental regulations, conditions and
inquiries. The most significant of these is the enforcement action which has
been brought by the DOJ, on behalf of the EPA, and which is discussed in
"Management's Discussion and Analysis of Results of Operations and Financial
Condition -- Financial Condition" and in Note 12 to the Consolidated Financial
Statements for the year ended July 31, 1994 included elsewhere herein. In
addition to the expenditures that will likely be incurred in connection with a
resolution of this matter, current or future environmental regulations likely
will require additional remediation or other expenditures at the Navajo and
Montana Refineries. The extent of any such expenditures cannot be presently
determined.
 
     The Company's operations are also subject to various laws and regulations
relating to occupational health and safety. The Company maintains safety,
training and maintenance programs as part of its ongoing efforts to ensure
compliance with applicable laws and regulations. Moreover, while recently
enacted comprehensive health and safety legislation have required, and will
continue to require, substantial expenditures and modifications of procedures,
the Company believes it is taking the appropriate steps to ensure compliance.
 
     Notwithstanding the Company's efforts, following an eight-month series of
inspections at MRC, the Occupational Safety and Health Administration recently
issued numerous citations alleging a variety of matters of noncompliance. MRC
has contested all citations and it cannot presently determine the extent of any
fines for which it will ultimately be responsible.
 
INSURANCE
 
     The Company's operations are subject to normal hazards of refinery
operations, including fire, explosion and weather-related perils. The Company
maintains various insurance coverages, including business interruption
insurance, subject to certain deductibles. The Company is not fully insured
against those risks that are not fully insurable or for which coverage is
unavailable or premium costs are prohibitive.
 
LEGAL PROCEEDINGS
 
     In July 1993, the DOJ, acting on behalf of the EPA, filed a complaint in
the United States District Court for the District of New Mexico alleging that
Navajo, beginning in September 1990 and continuing until the present, had
violated and continues to violate RCRA and implementing regulations of the EPA
by treating, storing and disposing of certain hazardous wastes without necessary
authorization and without compliance
 
                                       29
<PAGE>   31
 
with regulatory requirements. The complaint seeks a court order directing Navajo
to comply with these regulatory standards and civil penalties for the alleged
non-compliance. The Company believes that the parties are in the final stages of
negotiations that should resolve some, if not all, of the litigation. Based on
these negotiations, the Company would close the existing evaporation ponds of
its wastewater management system and implement an alternative waste water
treatment system. Any settlement with DOJ also is expected to involve payment of
a civil penalty. See "Investment Considerations -- Environmental Regulation,"
"Management's Discussion and Analysis of Results of Operations and Financial
Condition" and the Notes to the Consolidated Financial Statements included
elsewhere herein.
 
     The Company is a party to various other litigation and proceedings which it
believes, based on advice of counsel, will not have a material adverse impact on
its financial condition or results of operations.

     The Representatives have advised the Company and the Selling Stockholders
that the Underwriters propose to offer the shares of Common Stock to the public
initially at the public offering price set forth on the cover page of this
Prospectus, and to certain dealers at such price less a concession not in excess
of $          per share. The Underwriters may allow, and such dealers may
re-allow, a discount not in excess of $          per share on sales to certain
other dealers. After the public offering, the public offering price, concession
and discount may be changed.
 
     The Company and the Selling Stockholders have granted the Underwriters an
option, exercisable by the Representatives, to purchase up to 375,000 additional
shares of Common Stock at the initial public offering price, less the
underwriting discount. Such options, which expire 30 days after the date of this
Prospectus, may be exercised solely to cover over-allotments. To the extent that
the Representatives exercise such options, each of the Underwriters will be
obligated, subject to certain conditions, to purchase approximately the same
percentage of the option shares that the number of shares of Common Stock to be
purchased initially by that Underwriter bears to the total number of shares to
be purchased initially by the Underwriters.
 
     The Company and the Selling Stockholders have agreed to indemnify the
Underwriters against certain liabilities, including liabilities under the
Securities Act, or to contribute to payments the Underwriters may be required to
make in respect thereof.
 
     Each of the Company and the Selling Stockholders has agreed that it will
not, without the prior written consent of the Representatives, directly or
indirectly, sell, offer to sell, grant any option for the sale of or otherwise
dispose of, any shares of Common Stock or any security convertible into or
exchangeable or exercisable for any such shares of Common Stock for a period of
180 days from the date of this Prospectus.

                          REPORT OF ERNST & YOUNG LLP
                              INDEPENDENT AUDITORS
 
The Board of Directors
and Stockholders of Holly Corporation
 
     We have audited the accompanying consolidated balance sheet of Holly
Corporation (the "Company") at July 31, 1994 and 1993, and the related
consolidated statements of income, cash flows and stockholders' equity for each
of the three years in the period ended July 31, 1994. 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, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Holly Corporation at July 31, 1994 and 1993, and the consolidated results of its
operations and its cash flows for each of the three years in the period ended
July 31, 1994, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                          JULY 31, 1994, 1993 AND 1992
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
PRINCIPLES OF CONSOLIDATION
 
     The Company is principally engaged in the refining of petroleum products.
Although the Company is also engaged in certain oil and gas exploration and
production activities, such activities do not represent a significant segment of
the Company's assets or operations.
 
     The consolidated financial statements include the accounts of the Company,
its subsidiaries and Montana Refining Company, a Partnership (MRC).
 
CASH EQUIVALENTS
 
     For purposes of the statement of cash flows, the Company considers all
highly liquid investments with a maturity of three months or less at the time of
purchase to be cash equivalents.
 
INVENTORIES
 
     Inventories are stated at the lower of cost, using the last-in, first-out
(LIFO) method for crude oil and refined products and the average cost method for
materials and supplies, or market.
 
REVENUE RECOGNITION
 
     Sales and related cost of sales are recognized when products are shipped to
customers and title passes. Sales are reported exclusive of excise taxes.
 
DEPRECIATION
 
     Depreciation is provided by the straight-line method over the estimated
useful lives of the assets, primarily 10 to 30 years for refining and pipeline
facilities and 3 to 10 years for corporate and other assets.
 
OIL AND GAS EXPLORATION AND DEVELOPMENT
 
     The Company accounts for the acquisition, exploration, development and
production costs of its oil and gas activities using the successful efforts
method of accounting. Lease acquisition costs are capitalized; undeveloped
leases are written down when determined to be impaired and written off upon
expiration or surrender. Geological and geophysical costs and delay rentals are
expensed as incurred. Exploratory well costs are initially capitalized, but if
the effort is unsuccessful, the costs are charged against earnings. Development
costs, whether or not successful, are capitalized. Productive properties are
stated at the lower of amortized cost or estimated realizable value of
underlying proved oil and gas reserves. Depreciation, depletion and amortization
of such properties is computed by the unit-of-production method.
 
EARNINGS PER SHARE
 
     Earnings per share amounts are based upon the weighted average number of
common shares outstanding during each period.
 
FUTURES CONTRACTS
 
     The Company enters into futures contracts to hedge a portion of the price
risk associated with crude oil and refined products. Gains or losses on
contracts are recognized when the related inventory is sold or the hedged
transaction is consummated.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
                          JULY 31, 1994, 1993 AND 1992
 
2. ACCOUNTING CHANGE
 
     Effective August 1, 1992, the Company adopted Statement of Financial
Accounting Standards (SFAS) No. 109, "Accounting for Income Taxes", which amends
the accounting for income taxes from the deferral method to the liability
method. Under the liability method, deferred taxes are stated at the income tax
rates currently in effect or scheduled to be implemented rather than at the tax
rate in effect when the taxes were provided. The cumulative effect of this
accounting change through the 1992 fiscal year was a $958,000 increase in the
Company's deferred tax liability at August 1, 1992. This additional income tax
expense was reflected as a reduction of $958,000 in net income in the first
quarter of the 1993 fiscal year or $.12 per share. Excluding the provision for
the cumulative effect upon adoption of the new standard, the effect of the
change on net income was not material.

</TABLE>
 
     Crude oil resales accounts receivable principally represent the sell side
of reciprocal crude oil buy/sell exchange arrangements involved in supplying
crude oil to the refineries, with an approximate like amount reflected in
accounts payable. The net differential of these crude oil buy/sell exchanges is
reflected in cost of sales. The exchange differentials result principally from
crude oil type and location differences.
 
     Credit losses are provided for in the financial statements and consistently
have been minimal.

SENIOR NOTES
 
     In June 1991, the Company sold $80 million of Senior Notes to a group of
insurance companies. The Senior Notes were issued in two Series and are
unsecured. The Series A Notes are in the principal amount of $28 million, have a
7-year life, require equal annual principal payments of $5,600,000 beginning
June 15, 1994 and bear interest at 9.72%. The Series B Notes are in the
principal amount of $52 million, have a 10-year life, require equal annual
principal payments of $8,667,000 beginning June 15, 1996 and bear interest at
10.16%. The note agreement imposes certain restrictive covenants, including
limitations on liens, additional indebtedness, sale of assets, investments,
business combinations and dividends, which limitations collectively are less
restrictive than the terms of the bank Credit Agreement.
 
CREDIT AGREEMENT
 
     In July 1993, the Company and certain of its subsidiaries entered into a
new two-year bank Credit Agreement (Credit Agreement), which provides a $100
million facility for letters of credit or for direct borrowings of up to $25
million, with such borrowings being subject to an annual 20-day cleanup period.
Interest on borrowings is based upon, at the Company's option, (i) the agent
bank's prime rate plus  1/2% per annum; (ii) various Eurodollar related rates;
and (iii) various certificate of deposit related rates. A fee of 1% per annum is
payable quarterly on the outstanding balance of all letters of credit, and a
commitment fee of 3/8 of 1% per annum is payable on the unused portion of the
facility. The borrowing base for the facility consists of cash, cash
equivalents, accounts receivable and inventory, all of which secure the
facility. The Credit Agreement imposes certain restrictions, including: (i) a
prohibition of other indebtedness in excess of $3 million with exceptions for,
among other things, indebtedness under the Company's Senior Notes and certain
nonrecourse debt; (ii) maintenance of certain levels of net worth, working
capital and interest coverage; (iii) limitations on investments and dividends;
and (iv) a prohibition of incursions on controlling ownership, material changes
in senior management and business combinations with unaffiliated entities.
 
     At July 31, 1994, the Company had outstanding letters of credit totalling
$51,376,000 and no borrowings. The unused commitment under the Credit Agreement
at July 31, 1994 was $48,624,000, of which up to $25,000,000 may be used for
additional direct borrowings.

     The average and maximum amounts outstanding and the effective average
interest rate for borrowings under the Company's current and prior credit
agreements were as follows:

    Effective average interest rate........................     6.6%        6.6%        7.7%
</TABLE>
 
     The Senior Notes and Credit Agreement restrict investments and
distributions, including dividends, to an amount in the aggregate not to exceed
75% of cumulative consolidated net income (as defined). Under the most
restrictive of these covenants, at July 31, 1994 approximately $20.7 million was
available for the payment of dividends.
 
     Maturities of long-term debt for the next five fiscal years are as follows:
1995 -- $5,608,000; 1996 -- $14,275,000; 1997 -- $14,275,000;
1998 -- $14,275,000 and 1999 -- $8,675,000.
 
     The Company made interest payments of $8,744,000 in 1994, $9,058,000 in
1993 and $9,361,000 in 1992.
 
     Based on the borrowing rates that the Company believes would be available
for replacement loans with similar terms and maturities of the debt of the
Company now outstanding, the fair value of long-term debt including current
maturities would be $79.3 million at July 31, 1994.
 
7. INCOME TAXES
 
     Effective August 1, 1992, the Company adopted SFAS No. 109 to account for
income taxes (see Note 2).
 
     The statutory federal income tax rate applied to pre-tax book income
reconciles to income tax expense as follows:

(1)  Blended rate, as federal income tax rate changed effective January 1, 1993.
 
     Additionally, tax benefit of $56,000, $63,000 and $239,000 for dividends
paid in fiscal 1994, 1993 and 1992, respectively, to the Company's Employee
Stock Ownership Plan was directly credited to retained earnings.
 
     Operations of the corporation that was the sole limited partner of MRC
prior to the acquisition of such corporation by the Company (See Note 10)
resulted in unused net operating loss carryforwards of approximately $7,000,000,
which are expected to be available to the Company to a limited extent each year
through 2006 based on the income of such corporation. As of July 31, 1994,
approximately $6,000,000 of these net operating loss carryforwards remain
available to offset future income. For financial reporting purposes, any benefit
of these net operating loss carryforwards is being offset against any contingent
future payments relating to the acquisition of such corporation.

     Approximately 52% of plan assets is invested in equity securities and 48%
is invested in fixed income securities and other instruments at July 31, 1994.
 
EMPLOYEE STOCK OWNERSHIP PLAN
 
     In December 1985, the Company established an Employee Stock Ownership Plan
(ESOP). The ESOP is non-contributory and includes substantially all employees of
the Company and its subsidiaries who meet certain length of service requirements
and are not covered by a collective bargaining agreement.
 
     In 1985, the ESOP borrowed from the Company the $4,102,000 needed to
purchase 1,500,000 shares of the Company's common stock. The loan is repayable
in ten annual installments of $410,000 (subject to certain adjustments)
commencing August 1, 1986 and bears interest at 12% per annum. The Company is
obligated to make annual contributions sufficient to enable the ESOP to repay
the loan with interest. The unearned compensation of $4,102,000 was recorded as
a reduction of stockholders' equity and is being reduced as payments are made.
Interest income earned on the note due from the ESOP is offset against an equal
amount contributed to the ESOP by the Company.
 
10. MONTANA REFINING COMPANY, A PARTNERSHIP
 
     The Company acquired on July 31, 1992, the corporation that was the limited
partner in MRC in connection with a settlement of litigation. The acquisition
involved among other items contingent future payments of up to $189,000 per year
over the period 1993 through 2005.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
                          JULY 31, 1994, 1993 AND 1992
 
     As a consequence of the acquisition of the limited partner in MRC, certain
deferred taxes have been eliminated, resulting in a decrease for fiscal 1992 of
$2,579,000 in the provision for income taxes, of which $1,483,000 relates to
income taxes provided in prior years.
 
11. OTHER INCOME (EXPENSE)
 
     The amounts in other income (expense) relate principally to settlements.
The 1993 fiscal year included income of $4,000,000 relating to a settlement with
a common carrier pipeline concerning product pipeline distribution constraints.
The 1992 fiscal year included a charge of $700,000 relating to a settlement of a
lawsuit with the limited partner of MRC (see Note 10).
 
12. CONTINGENCIES
 
     In July 1993, the United States Department of Justice, acting on behalf of
the United States Environmental Protection Agency (EPA), filed a complaint in
the United States District Court for the District of New Mexico alleging that
the Company's subsidiary, Navajo Refining Company, beginning in September 1990
and continuing until the present, had violated and continues to violate the
Resource Conservation and Recovery Act (RCRA) and implementing regulations of
the EPA by treating, storing and disposing of certain hazardous wastes without
compliance with regulatory requirements. The complaint seeks a court order
directing Navajo to comply with these regulatory standards and civil penalties
for the alleged non-compliance.
 
     Navajo has answered the complaint, denying all the allegations of legal
liability and asserting affirmative defenses. Only limited discovery has been
conducted. The Company and Navajo have been contesting the Government's case as
necessary and appropriate, while contemporaneously exploring the prospects for
negotiated settlement.
 
     In this regard, a tentative resolution of a substantial portion of the
litigation has been reached. Under this approach, the Company would close the
existing evaporation ponds of its wastewater management system, at an
approximate cost of $1 to $2 million, to be expended over a several year period.
A reserve of $2 million was recorded in fiscal 1993, principally to provide for
the cost of closing existing ponds. In such event, the Company would implement
one of several alternatives to the existing wastewater treatment system.
Depending upon which approach is utilized, the Company could incur capitalizable
costs of an additional $5 to $10 million over the next several years.
 
     Assuming the Company consummates the settlement discussed above, the
remaining aspect of the litigation would be the civil penalty which the
Government seeks. While the amount of any such civil penalty cannot presently be
ascertained, based upon the advice of counsel, it is not believed that any such

position.

on its financial condition of operations.
 
13. SIGNIFICANT CUSTOMERS
 
     Virtually all revenues were domestic revenues (including domestic sales for
export to Mexico). Approximately $67,000,000 (12%) of the Company's revenues for
fiscal 1994, $65,000,000 (10%) of revenues for fiscal 1993 and $67,000,000 (13%)
for fiscal 1992 were from the sale of military jet fuel to the United States
Government. Approximately $58,000,000 (11%) of the Company's revenues for fiscal
1994 were from the sale of gasoline to an affiliate of PEMEX (the
government-owned energy company of Mexico). In addition to the United States
Government and PEMEX, another refiner, which is a purchaser of gasoline and

revenues in fiscal 1993 and $96,000,000 (19%) in fiscal 1992. While a loss of,
or reduction in amounts purchased by, major purchasers that resell to retail
customers could have an adverse effect on the Company, the Company believes that
the impact of such a loss on the Company's results of operations should be
limited because the Company's sales volume with respect to products whose
end-users are retail customers is more dependent on the general retail demand in
the Company's primary markets than on sales to any specific customer.

                               HOLLY CORPORATION
 
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE A -- PRESENTATION OF FINANCIAL STATEMENTS
 
     In the opinion of the Company, the accompanying consolidated financial
statements, which have not been audited by independent accountants (except for
the consolidated balance sheet as of July 31, 1994), reflect all adjustments
(consisting only of normal recurring adjustments, except for the accounting
change as described in Note B below) necessary to present fairly the Company's
consolidated financial position as of January 31, 1995, the consolidated results
of operations for the six months ended January 31, 1995 and 1994, and
consolidated cash flows for the six months ended January 31, 1995 and 1994.
 
     Certain notes and other information have been condensed or omitted.
Therefore, these financial statements should be read in conjunction with the
consolidated financial statements and related notes included in the Company's
Annual Report on Form 10-K for the fiscal year ended July 31, 1994.
 
     References herein to the "Company" are for convenience of presentation and
may include obligations, commitments or contingencies that pertain solely to one
or more affiliates of the Company. Results of operations for the first six
months of fiscal 1995 are not necessarily indicative of the results to be
expected for the full year.
 
NOTE B -- ACCOUNTING CHANGE
 
     Effective August 1, 1994, the Company changed its method of accounting for
turnaround costs. Turnarounds consist of preventive maintenance on major
processing units as well as the shutdown and restart of all units, and generally
are scheduled at two to three year intervals. Previously, the Company estimated
the costs of the next scheduled turnaround and ratably accrued the related
expenses prior to the actual turnaround. To provide for a better matching of
turnaround costs with revenues, the Company changed its accounting method for
turnaround costs to one that results in the amortization of costs incurred over
the period until the next scheduled turnaround. The cumulative effect of this
accounting change through the 1994 fiscal year was an increase in net income in
the current year of $5,703,000, or $.69 per common share. Excluding the
cumulative effect, the change increased net income for the second quarter of
fiscal 1995 by $102,000 or $.01 per common share and increased net income for
the six months ended January 31, 1995 by $1,022,000 or $.12 per common share. If
the accounting change for turnaround costs had been retroactively applied, pro
forma net income for both the quarter and the six months ended January 31, 1994
would have increased by $1,058,000 or $.13 per share over what was originally
reported and net income for the full 1994 fiscal year would have increased by
$1,266,000 or $.15 per share to pro forma net income amounts for the 1994 fiscal
year of $21,983,000 or $2.66 per share.
 
NOTE C -- CONTINGENCIES
 
     In July 1993, the DOJ filed suit against Navajo alleging that, beginning in
September 1990 and continuing through the present, Navajo has violated and
continues to violate RCRA and implementing regulations of the EPA by treating,
storing and disposing of certain hazardous wastes without compliance with
regulatory requirements. The Company believes that the parties are in the final
stage of negotiations that should resolve some, if not all, of the litigation.
Based on those negotiations, the Company would close the existing evaporation
ponds of its wastewater management system, at a cost of approximately $1 million
to be expended over a several year period. The negotiations also contemplate
that the Company would implement one of several alternatives to the existing
wastewater treatment system. Depending upon which approach is utilized, the
Company could incur total costs of approximately $3 million over the next
several years. The costs to implement an alternative wastewater treatment system
would be capitalized and amortized over the future useful life of the resulting
asset in accordance with generally accepted accounting principles. Any
settlement with the DOJ also is expected to involve the payment of a civil
penalty, which, based on negotiations among the Company, the EPA and the DOJ,
the Company does not believe will have a material adverse effect on its
financial position or results of operations. In fiscal 1993, the Company
recorded a $2 million reserve for the litigation, principally to provide for the
cost of closing the existing ponds.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     The law of the State of Delaware authorizes corporations to limit the
personal liability of directors to corporations and their stockholders for
monetary damages for certain breaches of a director's fiduciary duties. The
Registrant's Restated Certificate of Incorporation provides that a director will
not be personally liable for monetary damages for the breach of his or her
fiduciary duties as a director, except for liability imposed by the General
Corporation Law of the State of Delaware or imposed by other law for (i) a
breach of the director's duty of loyalty to the Registrant or its stockholders,
(ii) acts or omissions not in good faith or which involve intentional misconduct
or a knowing violation of law, or (iii) a transaction from which the director
derived an improper personal benefit.
 
     The Bylaws of the Registrant provide that the Registrant shall indemnify
any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding (other than an
action by or in the right of the Registrant) by reason of the fact that he is or
was a director, officer, employee or agent of the Registrant, to the fullest
extent permitted by the General Corporation Law of the State of Delaware
provided such person gives the Registrant appropriate notice and permits the
Registrant, at its option, to participate in or to direct in good faith any
defense of such person. Pursuant to the provisions of Section 145 of the General
Corporation Law of the State of Delaware, the Registrant has the power under
specified circumstances to indemnify such persons against expenses, judgments,
fines and amounts paid in settlement actually and reasonably incurred in
connection with such action, suit or proceeding.
 
     The power to indemnify generally applies only if such person acted in good
faith and in a manner he or she reasonably believed to be in the best interest,
or not opposed to the best interest, of the Registrant and, with respect to any
criminal action or proceeding, had no reasonable cause to believe his conduct
was unlawful. In actions brought by or in the right of the Registrant, however,
the power to indemnify applies only to expenses reasonably incurred in
connection with the defense and settlement of an action or suit and not to the
satisfaction of a judgment or settlement of the claim itself, and with the
further limitation that in such actions no indemnification shall be made in the
event of any adjudication of liability for the Corporation unless the court, in
its discretion, believes that in light of all the circumstances indemnification
should apply. The General Corporation Law of the State of Delaware further
specifically provides that the indemnification authorized thereby shall not be
deemed exclusive of any other rights to which any such officer or director may
be entitled under any bylaws, agreements, vote of stockholders or disinterested
directors, or otherwise.
 
                                      II-1
<PAGE>   58
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended (the "Securities Act") may be permitted to directors,
officers and controlling persons of the Registrant pursuant to the provisions
referred to above in this Item 15, 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 of 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.
