ITEM 1. BUSINESS AND ITEM 2. PROPERTIES.
 
     Pennzoil Company ("Pennzoil") is an energy company engaged primarily in oil
and gas exploration and production, in processing, refining and marketing of oil
and motor oil and refined products and in fast automotive oil change operations.
Pennzoil's operations are conducted primarily through subsidiaries. Pennzoil
Exploration and Production Company conducts the majority of Pennzoil's oil and
gas exploration and production operations. The refining of oil and the
processing and marketing of motor oil, refined products and industrial
specialties are conducted by Pennzoil Products Company ("PPC"). Jiffy Lube
International, Inc. ("Jiffy Lube") franchises, owns and operates automotive fast
lubrication and fluid maintenance service centers. Richland Development
Corporation ("Richland") manages Pennzoil's real estate holdings and provides
staff support for Pennzoil and its subsidiaries.
 
     In December 1994, Pennzoil merged its Pennzoil Exploration and Production
Company subsidiary into its Pennzoil Petroleum Company ("Pennzoil Petroleum")
subsidiary, and the name of the surviving corporation was subsequently changed
to Pennzoil Exploration and Production Company ("PEPCO").
 
     In October 1994, Pennzoil entered into an agreement with Freeport-McMoRan
Resource Partners, Limited Partnership ("Freeport-McMoRan") providing for the
sale by Pennzoil to Freeport-McMoRan of substantially all the domestic assets of
Pennzoil's sulphur segment. The transaction was completed in January 1995.
Pennzoil continues to own and operate its Antwerp, Belgium sulphur terminal and
the related international sulphur business. Reference is made to "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Sulphur" for additional information.
 
     As of December 31, 1994, Pennzoil beneficially owned 18,071,036 shares of
common stock of Chevron Corporation ("Chevron"), which have been deposited with
exchange agents for possible exchange for $402.5 million and $500.0 million
principal amount of exchangeable debentures of Pennzoil due January 15, 2003 and
October 1, 2003, respectively, at exchange rates equivalent to $42 1/16 and
$58 13/16 per share of Chevron common stock, respectively. At the current
dividend rate, Pennzoil receives $33.4 million annually in dividends on the
18,071,036 Chevron shares. Reference is made to "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Capital Resources
and Liquidity" for additional information.

 (1) For 1994 and 1992, these amounts primarily represent dividend income from
     Pennzoil's investment in Chevron common stock. For 1993, this amount
     primarily represents a pretax gain of $171.6 million from Pennzoil's sale
     of 8,158,582 shares of Chevron common stock for a net price of $88.38 per
     share and dividend income from Pennzoil's investment in Chevron common
     stock.
 
 (2) Substantially all intersegment sales, which are priced at market, are from
     the oil and gas segment to the motor oil and refined products segment.
 
 (3) In October 1994, Pennzoil settled a dispute with the Internal Revenue
     Service ("IRS") relating to a proposed tax deficiency based on an audit of
     Pennzoil's 1988 federal income tax return. In connection with this
     settlement, Pennzoil paid $556.0 million to the IRS in October 1994 from
     cash, cash equivalents and current marketable securities and other
     investments on hand. In addition, as a result of the IRS settlement,
     Pennzoil increased the balance of its investment in Pennzoil Petroleum
     capital stock for financial reporting purposes and, therefore, the carrying
     value of Pennzoil Petroleum's oil and gas properties by $390.3 million, and
     such increased investment resulted in a $93.9 million increase in
     depreciation, depletion and amortization expense recognized in October 1994
     relating to Pennzoil Petroleum's oil and gas properties from the date of
     the acquisition of Pennzoil Petroleum to the date of the IRS settlement.
     These adjustments resulted in a net increase in property, plant and
     equipment of $296.4 million as of September 30, 1994, while interest
     charges and depreciation, depletion and amortization expense adjustments
     related to the IRS settlement reduced Pennzoil's 1994 pretax income by
     $388.2 million. Reference is made to "Management's Discussion and Analysis
     of Financial Condition and Results of Operations -- Oil and Gas" and Notes
     8 and 10 of Notes to Consolidated Financial Statements for additional
     information.
 
 (4) As of September 30, 1994, PPC ceased the processing of crude oil at its
     refinery in Roosevelt, Utah. In connection therewith, PPC recorded a total
     charge of $32.5 million, $24.3 million of which was charged to
     depreciation, depletion and amortization expense. Reference is made to
     "Management's Discussion and Analysis of Financial Condition and Results of
     Operations -- Motor Oil & Refined Products" for additional information.
 
 (5) In October 1994, Pennzoil entered into an agreement with Freeport-McMoRan
     providing for the sale by Pennzoil to Freeport-McMoRan of substantially all
     the domestic assets of Pennzoil's sulphur segment. In connection with this
     transaction, Pennzoil's sulphur segment recorded a charge to depreciation,
     depletion and amortization expense of $50.2 million in September 1994.
     Reference is made to "Management's Discussion and Analysis of Financial
     Condition and Results of Operations -- Sulphur" for additional information.
 
 (6) Includes interest capitalized of $9,027,000, $11,420,000 and $8,731,000 in
     1994, 1993 and 1992, respectively.
 
 (7) For 1994, capital expenditures for the oil and gas segment include
     $230,924,000 allocated to the oil and gas properties added as a result of
     the acquisition of Co-enerco Resources Ltd. ("Co-enerco"). Reference is
     made to Note 10 of Notes to Consolidated Financial Statements for
     additional information. For 1992, capital expenditures for the oil and gas
     segment include $1,009,410,000 allocated to the oil and gas properties
     added as a result of the acquisition of Pennzoil Petroleum. Reference is
     made to "Management's Discussion and Analysis of Financial Condition and
     Results of Operations -- Capital Resources and Liquidity" and Note 10 of
     Notes to Consolidated Financial Statements for additional information.
     Capital expenditures for 1994 do not include any amounts paid with respect
     to the IRS settlement discussed in footnote (3) above.
 
     Narrative descriptions of these business segments follow, with emphasis on
1994 developments. Unless otherwise indicated by the context, references to
Pennzoil include its subsidiaries.

OIL AND GAS
 
     In the oil and gas segment, Pennzoil engages in the acquisition,
exploration, exploitation and development of prospective and proved oil and gas
properties, the production and sale of crude oil, condensate and natural gas
liquids and the production, treatment and sale of natural gas. The bulk of
Pennzoil's production is derived from established fields in Texas, Louisiana,
Utah, Alberta and federal waters offshore Louisiana, Texas and California.
 
     In October 1992, Pennzoil completed a tax-free transaction with Chevron,
pursuant to which Pennzoil exchanged 15,750,000 shares of Chevron common stock
beneficially owned by Pennzoil for all the capital stock of Pennzoil Petroleum,
which owned Gulf of Mexico, Gulf Coast, Permian Basin and other domestic oil and
gas producing properties. In June 1994, Pennzoil Canada, Inc. ("Pennzoil
Canada"), an indirect wholly owned subsidiary of Pennzoil, acquired Co-enerco, a
Canadian oil and gas exploration and production company operating in Alberta,
northeastern British Columbia and southeastern Saskatchewan. The results of
operations of Pennzoil Petroleum and Co-enerco subsequent to October 30, 1992
and June 30, 1994, respectively, have been included in Pennzoil's oil and gas
segment results. Reference is made to "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Oil and Gas" and Note 10 of
Notes to Consolidated Financial Statements for additional information.
 
     OIL AND GAS RESERVES. The following table sets forth information regarding
Pennzoil's net proved reserves and the present value (discounted at 10%) of the
estimated future net cash flows before deduction of income taxes from the
production and sale of those reserves. The reserves are reported by Ryder Scott
Company Petroleum Engineers, Houston, Texas ("Ryder Scott") and Outtrim Szabo
Associates Ltd., Calgary, Canada ("Outtrim Szabo") in accordance with criteria
prescribed by Statement of Financial Accounting Standards ("SFAS") No. 69,
"Disclosures About Oil and Gas Producing Activities." The summary reports of
Ryder Scott and Outtrim Szabo on the reserve estimates as of December 31, 1994,
which include certain definitions and assumptions, are set forth as exhibits to
this Annual Report on Form 10-K. Such information as to reserve estimates
includes reserves of each of PEPCO, Pennzoil Canada, PPC and Pennzoil. The
summary reports of Ryder Scott on the reserve estimates as of December 31, 1993
and 1992 are included in Pennzoil's previously filed Annual Reports on Form 10-K
for the respective years.
 
     Information regarding ownership interests, prices, costs and other factual
data was furnished to Ryder Scott and Outtrim Szabo by Pennzoil. To facilitate
timely issuance of the reserve estimates, estimated production data were used
for the last few months of each year. Pennzoil believes that use of the actual
production data would not have resulted in any material change in the estimates
of reserves or pretax future net cash flows.

(1) Developed acreage represents the spacing units or other acreage assignable
    to productive wells.
(2) Undeveloped acreage is acreage on which wells have not been drilled or
    completed to a point that would permit the production of commercial
    quantities of oil and gas, regardless of whether such acreage contains
    proved reserves.
(3) Acreage in foreign areas other than Canada is operated under production
    sharing arrangements, service contracts or other contractual arrangements
    not involving lease or fee ownership.

 (1) "Gross Wells" includes all wells in which Pennzoil has an interest. "Net
     Wells" reflects Pennzoil's percentage ownership interest in each "Gross
     Well." One or more completions in the same bore hole are counted as one
     well. Any well in which one of multiple completions is an oil completion is
     classified as an oil well.
 
     PRODUCTION AND SALES. The following table summarizes the average daily
production of Pennzoil, net of all royalties, overriding royalties and other
outstanding interests for the periods indicated. Natural gas production refers
only to marketable production of natural gas on an "as sold" basis.

 (1) For purposes of providing common units of measure, natural gas is converted
     to a Btu-equivalent barrel of liquid on the basis of relative energy
     content (6 Mcf per barrel).
 
 (2) Production (lifting) costs are costs incurred to operate and maintain wells
     and related equipment and facilities. They do not include depreciation,
     depletion and amortization of capitalized acquisition, exploration and
     development costs, exploration expenses, general and administrative
     expenses, interest expense or income tax. Differences between sales prices
     and production (lifting) costs do not represent profit.
 
     Pennzoil sells its crude oil and condensate production generally at posted
field prices less any applicable transportation charges, its natural gas liquids
production at negotiated prices and its natural gas production generally under a
combination of 30-day spot, short-term and long-term sales contracts.
 
     Pennzoil has substantial control in marketing its natural gas production.
Pennzoil's natural gas marketing efforts are primarily constrained only by
normal free marketplace competition and by regulatory limitations generally
described below under the caption "Government Regulation." In February 1995,
Pennzoil and Brooklyn Union Gas Co. announced that their subsidiaries, Pennzoil
Gas Marketing Company and BRING Gas Services Corp., would form a 50-50 gas
marketing joint venture. Pennzoil currently expects to contribute approximately
$3 million in cash to the venture and to commit substantially all of its natural
gas production from the continental U.S. to be marketed through the venture.
 
     Since 1986, Pennzoil has restricted spot gas sales from time to time during
periods when prices have fallen below levels considered acceptable. Pennzoil did
not restrict spot gas sales in 1994.
 
     DRILLING ACTIVITY. The following table shows Pennzoil's net productive and
dry exploratory and development wells completed for the periods shown.
Completion occurs upon the installation of permanent equipment for the
production of oil or gas, or, in the case of dry holes, upon reporting
abandonment to the appropriate regulatory agency.

 (1) For purposes of this tabulation, a productive well is an exploratory or a
     development well that is not a dry hole. One or more completions in the
     same bore hole are counted as one well. Any well in which one of multiple
     completions is an oil completion is classified as an oil well.
 
 (2) A dry hole is an exploratory or development well found to be incapable of
     producing either oil or gas in sufficient quantities to justify completion
     as an oil or gas well.
 
     As of December 31, 1994, Pennzoil was participating in the drilling or
awaiting completion of 47 gross (41 net) wells onshore and 14 gross (8 net)
wells offshore the United States.

     EXPLORATION, DEVELOPMENT AND PRODUCTION ACTIVITIES. In North America, oil
and gas production volumes rose substantially in 1994 primarily as a result of
accelerated Gulf of Mexico drilling and the addition of the oil and gas
properties of Co-enerco. During the fourth quarter of 1994, Pennzoil produced an
average of approximately 198,000 barrels of oil equivalent ("BOE") per day
compared to an average of approximately 173,000 BOE per day during the first
quarter of 1994. Total production costs and expenses per barrel, excluding
exploration expense and depreciation, depletion and amortization expense, were
reduced 10% in 1994, to $5.32 per BOE.
 
     Pennzoil disposed of approximately 90 producing oil and gas fields in 1994,
continuing its asset highgrading program begun in 1992, and decreasing the
number of producing fields in which Pennzoil had an interest from approximately
800 in early 1993 to approximately 400 at the end of 1994. Reference is made to
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Capital Resources and Liquidity -- Assessment of Oil and Gas
Properties" for additional information.
 
     In June 1994, Pennzoil Canada acquired Co-enerco, a Canadian oil and gas
exploration and production company operating in Alberta, northeastern British
Columbia and southeastern Saskatchewan. Pennzoil Canada paid $230.9 million in
cash in connection with the acquisition of Co-enerco and the repayment of Co-
enerco's outstanding bank debt, which was financed primarily through two credit
facilities. Reference is made to Notes 3 and 10 of Notes to Consolidated
Financial Statements for additional information. Total net proved reserves of
15.9 million barrels of oil and 160 billion cubic feet of gas were added through
the Co-enerco acquisition.
 
     Internationally, in September 1994, the State Oil Company of the Azerbaijan
Republic ("SOCAR") and a consortium of foreign oil companies, which includes
Pennzoil, signed an oil production sharing contract for development of the
Azeri, Chirag and a deep-water portion of the Guneshli fields in the Caspian
Sea. The contract was ratified by the National Parliament of the Republic of
Azerbaijan in November 1994 and was made effective in December 1994. The
contract covers the basic tenets of the project, including profit splits,
taxation, project management mechanism, legal issues, hiring practices and other
details. The combined fields are located 120 miles offshore in the southern
portion of the Caspian Sea in approximately 400 feet of water. Aggregate capital
investment for all the participants in the consortium is estimated to be between
$7 and $8 billion over the 30-year life of the project to develop an estimated 4
billion barrels of recoverable reserves. Participants in the development and
their respective interests are SOCAR (20.00%), Amoco (17.01%), British Petroleum
(17.127%), Delta-Nimir (1.68%), Lukoil (10.00%), McDermott (2.45%), Pennzoil
(9.82%), Ramco (2.08%), Statoil (8.563%), Turkish Petroleum Company (1.75%) and
Unocal (9.52%). The contract includes a $300 million bonus to be paid by the
consortium to the government of Azerbaijan in a phased manner over the life of
the project. Reference is made to "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Oil and Gas" for additional
information.
 
     Net reserves to the participants in the production sharing contract will
generally be dependent on the fields' reserves as well as on crude oil prices
and capital and operating expenditures. Pennzoil's 9.82% share has the potential
to add net reserves estimated in the range of 300 million barrels once the area
is developed. A study is under way to determine the feasibility of producing
from an existing platform in the Chirag Field; if feasible, production could
begin by late 1996. The consortium is also studying possible routes for a major
export pipeline, which will be a prerequisite for transporting any oil produced
from the fields to international markets.
 
     Also in Azerbaijan, Pennzoil completed work on a comprehensive gas
gathering and compression system during 1994. This project is designed to
capture, compress and transport to shore approximately 150 million cubic feet
per day of gas that was being vented from the Guneshli Field. The gas
utilization project accounted for approximately $48 million in capital
expenditures for the oil and gas segment in 1994. The project will save
Azerbaijan an estimated $100 million annually that otherwise would have been
spent on imported natural gas. Pennzoil's total investment related to its
Azerbaijan activities, including the gas utilization project, was $166 million
as of December 31, 1994. Pennzoil's investment in the gas utilization project is
being recovered through partial credit toward Pennzoil's portion of the first
bonus payment made by members of the consortium of foreign oil companies to the
government of Azerbaijan, direct hard-currency payments by the
 
                                        8
<PAGE>   10
 
Azerbaijan government during 1995 and an interest in another project. Any
remaining balance due from the government of Azerbaijan with respect to the gas
utilization project will be creditable against the remaining bonus payments to
be made to the Azerbaijan government by the consortium. Reference is made to
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Oil and Gas" for additional information.
 
     In July 1994, Pennzoil Qatar, Inc. ("Pennzoil Qatar"), an indirect wholly
owned subsidiary of Pennzoil, was awarded the rights to explore acreage of Block
8 offshore Qatar. The block is located 50 miles from shore in the Arabian Gulf
and is adjacent to three large producing oil fields. Block 8 is approximately
the size of 117 Gulf of Mexico blocks, with water depths ranging from 100-120
feet. The technology and geological drilling risks involved are similar to the
Gulf of Mexico. Under the production sharing agreement, Pennzoil Qatar has
committed to a seismic acquisition and drilling program over the next four
years. Seismic acquisition is planned for the second quarter of 1995; drilling
will begin late this year or early in 1996, with four wells planned over the
next several years.
 
     In November 1994, Pennzoil Egypt, Inc., an indirect wholly owned subsidiary
of Pennzoil, and its Spanish partner, Repsol Exploracion Egypto S.A., were
selected to explore the Southeast Gulf of Suez Block offshore Egypt. The block,
which is approximately the size of 44 Gulf of Mexico blocks, surrounds the Shoab
Ali oil field, which has significant oil reserves in place. The agreement
requires approval by the Egyptian Oil ministry, cabinet and parliament. The
agreement calls for acquisition of 3-D seismic data and the drilling of one well
over the next two years following final approval of the agreement.
 
     Pennzoil's capital budget currently provides that its capital expenditures,
including interest capitalized, for domestic and international petroleum
exploration and development during 1995 are estimated to be $334.2 million
compared to $399.5 million of capital expenditures in 1994, excluding
expenditures related to the acquisition of Co-enerco. Reference is made to
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Capital Resources and Liquidity" for additional information.
 
     Pennzoil conducts or participates in certain offshore oil and gas
operations which are subject to the hazards of marine operations, such as
capsizing, collision and adverse weather and sea conditions, as well as risks of
blowouts and fires, which are generally present in all oil and gas drilling. In
the past, production from offshore blocks has been delayed on several occasions
as a result of pipeline breaks, hurricanes, blowouts and other unforeseen
events. In addition, Pennzoil's foreign oil and gas operations are subject to
certain risks, such as nationalization, confiscation, renegotiation of existing
contracts and currency fluctuations. Pennzoil monitors political, regulatory and
economic developments in any foreign countries in which it operates.
 
MOTOR OIL & REFINED PRODUCTS
 
     Pennzoil's motor oil and refined products operations are conducted by PPC.
These operations include the procurement and refining of crude oil and the
blending, packaging and marketing of motor oil and refined products.
 
     MANUFACTURING. PPC owns and operates two lube oil and specialty refineries,
one located near Oil City, Pennsylvania ("Rouseville") and the other, operated
by PPC's wholly owned subsidiary, Atlas Processing Company ("Atlas"), located in
Shreveport, Louisiana. The paraffinic lube base stocks produced by these
refineries are used primarily in the blending of motor oil and other lubricants
by PPC's marketing division. The lube oil and specialty refineries also produce
waxes, petrolatums, special cut kerosenes, transformer oils, process oils and
other naphthenic base oils for use in producing industrial specialty products or
for sale to industrial customers. Jet fuel is also supplied by the Atlas
refinery to several commercial airlines.
 
     As of September 30, 1994, PPC ceased the processing of crude oil at its
refinery in Roosevelt, Utah. PPC plans to continue purchasing crude oil from the
Bluebell-Altamont field and other nearby fields and will maintain a
transportation terminal at the refinery site.

(1) As of September 30, 1994, Pennzoil ceased the processing of crude oil at its
    refinery in Roosevelt, Utah. Reference is made to "Management's Discussion
    and Analysis of Financial Condition and Results of Operations -- Motor Oil &
    Refined Products" for more information.
 
     PPC purchases from others the requirements of its marketing operations not
produced in its own refineries.
 
     PPC owns and operates two lubricating specialty plants located in Karns
City, Pennsylvania and Dickinson, Texas. These plants manufacture petrolatums,
white oils, ink solvents, sulfonates, waxes and other specialty petroleum
products using feedstocks from PPC's refineries. These products are marketed by
PPC's PENRECO(R) and MAGIE BROS(R) divisions directly to manufacturers and
end-users. Additionally, Pennzoil continues to expand industrial specialty sales
into international markets, particularly in Asia, South America and Central
America.
 
     PPC also owns the Eureka Pipe Line Company, which operates a crude oil
gathering system in West Virginia.
 
     In June 1994, Conoco, Inc. ("Conoco") and Pennzoil agreed to carry out a
joint venture project at Conoco's refinery in Lake Charles, Louisiana. Operating
through a 50-50 joint venture, the companies will construct a new,
state-of-the-art lube oil hydrocracker facility estimated to cost approximately
$500 million, which is expected to be funded with project financing. The
facility will produce more than 16,000 barrels per day of high-quality base
oils, the base ingredient in finished lubricants. Site preparation began in the
third quarter of 1994, and the facility is expected to be completed in early
1997. Conoco is acting as construction manager and operator of the plant with
support positions staffed by both companies. The facility is intended to make
PPC substantially self-sufficient in low-cost, high-quality lube base stocks.
Additionally, engineering design is under way for a residual catalytic cracking
unit at the Atlas refinery, which should substantially lower the effective cost
of base oils produced at the facility.
 
     In September 1994, Pennzoil and the Polymers Division of Petrolite
Corporation ("Petrolite") agreed in principle to form the BARECO(R) Products
Company, a 50-50 partnership aimed at providing a broad line of wax products to
domestic and international purchasers of paraffin, microcrystalline and related
synthetic
 
                                       10
<PAGE>   12
 
waxes. Pennzoil will transport partially refined feedstock from Utah to its
Rouseville refinery, which will produce paraffinic waxes and related products.
The new wax products, along with certain waxes from Petrolite and existing wax
products from Pennzoil's Atlas and Rouseville refineries, will be sold through
the partnership. More than $23 million will be invested by Pennzoil at its
Rouseville refinery and its packaging plant in nearby Reno, Pennsylvania in
connection with this venture. Marketing will begin in April 1995.
 
     MARKETING. PENNZOIL(R) motor oil and lubricants are produced in six
domestic company-owned and operated blending and packaging plants (Alameda,
California; Portland, Oregon; Shreveport, Louisiana; Rouseville, Pennsylvania;
Vernon, California; and St. Louis, Missouri). In addition, two industrial
packaging plants, one located in Mundy's Corner, Pennsylvania and the other in
Marion, Illinois, produce lubricants for the commercial and industrial markets.
 
     PENNZOIL(R) products are sold in all 50 states through 160 independent
distributors and 66 company-owned distribution facilities. Additionally,
PENNZOIL(R) brand gasoline is marketed through approximately 364 retail outlets
located in Pennsylvania, Ohio, New York, Virginia, West Virginia, Tennessee and
Kentucky. Kerosenes, diesel oils, fuel oils and other distillates are marketed
at both the retail and wholesale levels through distributors.
 
     PPC competes with a number of other companies in the sale of motor oil and
refined products. Competition is based on price, service and quality, with
quality being of particular importance in the case of motor oils and other
petroleum specialty products.
 
     Domestically, growth in the motor oil industry is expected to remain low
for the foreseeable future. Changes in consumer buying habits and in
distribution channels used to bring products to market are expected to continue
to affect all motor oil marketers. Large mass merchandisers and auto parts
chains are expected to increasingly be the channel of choice for consumers who
buy and change their own motor oil. Consumers who have oil changes performed for
them are, in greater numbers, turning to "fast lube" outlets for this service.
 
     PPC is continuing its efforts to maintain PENNZOIL(R) as the leading motor
oil used by the installed market segment (fast lubes, service stations, auto
dealers, etc.). The installed market is expected to grow faster than the
industry as a whole. As consumers become increasingly concerned about the
environmental issues associated with changing their own oil, a continuing shift
to installers, who are generally better prepared to handle the disposition of
used oil and filters, is expected. Approximately 40% of all oil changes are done
by installers. Fast lube operations, by making oil changes convenient for the
consumer, are capturing an even larger share of the installed market by
attracting consumers who no longer change their own oil as well as business from
the other installer outlets (service stations, auto dealers, etc.). This shift,
which has been occurring since the early 1980s, is expected to continue. PPC
remains well-positioned within the installed market segment and is continuing
its efforts to satisfy the needs of this customer group to assure that the
benefits associated with this expected growth will be fully realized.
 
     PPC is also one of America's leading marketers of fuel injector and
carburetor cleaners and other car care products under the GUMOUT(R) name. These
products are sold primarily to the consumer trade in the retail channels, but
GUMOUT(R) has an increasing presence in the installed market. WOLF'S HEAD(R)
lubricants are also marketed as a secondary value-priced line throughout the
U.S., alongside the PENNZOIL(R) lubricants brand.
 
     PENNZOIL(R) motor oil and lubricants are marketed in 58 countries through
41 distributors, three licensees, four joint ventures and nine company-owned
marketing distribution centers. PPC has been active in Europe for many years and
in 1994 reorganized its Northern European operation to further capitalize on the
growth opportunities in that region. Part of that expansion has been focused on
emerging Eastern European countries, as well as a targeted marketing effort to
expand its presence in Italy.
 
     In 1994, PPC purchased the company's partner in Spain, now called Pennzoil
Iberica, to further support the opportunity for increasing volume in Southern
Europe. PPC also entered into an equity position in 1994 with Industria de
Lubricantes Bolivianos S.A., its licensee in Bolivia, and PENNZOIL(R) has become
the second largest selling brand in the market in under a year. The continued
expansion in other areas of South America in 1994 will result in a strong
presence for the PENNZOIL(R) brand in Ecuador, Chile, Colombia,
 
                                       11
<PAGE>   13
 
Peru and Argentina in 1995. PPC's position in Australia, where PENNZOIL(R) motor
oil is available in all states, grew steadily in 1994. Construction of a new
refining, blending and packaging plant is scheduled for completion in 1995 by
PPC's licensee in Indonesia, where PPC is the country's only
government-authorized private manufacturer of branded lubricants. PPC's joint
venture operation in India continued to realize substantial growth in sales and
market share during 1994. PPC has also begun the process of expansion into new
markets such as Brazil, Vietnam and China.
 
     PPC considers the above-mentioned trademarks used in its motor oil and
refined products operations to have significant marketing value, primarily in
identifying Pennzoil and its products.
 
     The following table sets forth information with respect to quantities sold
externally by the marketing and manufacturing operations during the years
indicated.

     At December 31, 1994, 1,141 JIFFY LUBE(R) service centers were open
worldwide, including 1,132 in the United States. Domestically, franchisees
operated 706 of the service centers and Jiffy Lube operated the remaining 426.
The service centers generally are clustered in metropolitan areas throughout the
United States.
 
SULPHUR
 
     In October 1994, Pennzoil entered into an agreement with Freeport-McMoRan
providing for the sale by Pennzoil to Freeport-McMoRan of substantially all the
domestic assets of Pennzoil's sulphur segment. The transaction was completed in
January 1995. Included in the sale were the Culberson mine in West Texas, the
sulphur terminals and loading facilities in Galveston, Texas and Tampa, Florida,
the charter of a marine sulphur tanker, two sulphur barges, 503 leased or owned
railcars and associated commercial contracts and obligations. Pennzoil continues
to own and operate its Antwerp, Belgium sulphur terminal and the related
international sulphur business. Reference is made to "Management's Discussion
and Analysis of Financial Condition and Results of Operations -- Sulphur" for
additional information.

</TABLE>
 
     The increase in employees as of December 31, 1994 and 1993, respectively,
is primarily attributable to an increase in the number of company-owned service
centers in the franchise operations segment.
 
     Approximately 9% of Pennzoil's employees are represented by various labor
unions. Collective bargaining agreements are in force with most of the unions.
 
     Pennzoil is subject to various federal and state laws and regulations
governing employment practices and working conditions, including Title VII of
the Civil Rights Act of 1964, as amended, the Equal Pay Act of 1963, the Civil
Rights Act of 1991, the Americans with Disabilities Act of 1990, the Family and
Medical Leave Act of 1993, the Drug Free Workplace Act of 1989, the Age
Discrimination in Employment Act of 1967, as amended, the Rehabilitation Act of
1973, as amended, the Vietnam Era Veterans' Readjustment Assistance Act of 1974,
as amended, the Occupational Safety and Health Act of 1970, the Fair Labor
Standards Act of 1938, as amended, the National Labor Relations Act of 1935, as
amended, and Executive Order 11246.
 
GOVERNMENT REGULATION
 
     Pennzoil's operations are affected from time to time in varying degrees by
political developments and federal and state laws and regulations. In
particular, oil and gas operations and economics are affected by changing price
control, tax and other laws relating to the petroleum industry and by constantly
changing administrative regulations.
 
     NATURAL GAS ACT, NATURAL GAS POLICY ACT AND NATURAL GAS WELLHEAD DECONTROL
ACT. Until recently, Pennzoil and other natural gas producers were subject to
comprehensive sales price and service regulation by the Federal Energy
Regulatory Commission ("FERC") under the Natural Gas Act and the Natural Gas
Policy Act of 1978. However, the Natural Gas Wellhead Decontrol Act of 1989
provided for the phased elimination of all remaining federal natural gas pricing
and sales regulation of "first sales", including all wellhead sales and sales by
nonpipeline marketing entities, by January 1, 1993. As a result, all natural gas
sales by Pennzoil can be made at market prices.
 
     The FERC's jurisdiction over the interstate natural gas transportation
industry was unaffected by the Natural Gas Wellhead Decontrol Act. However, as a
result of "first sale" deregulation and in an effort to increase competition in
the selling and purchasing of natural gas, the FERC has issued a series of
orders that have led to the restructuring of the interstate pipelines' rates and
services and the granting to the pipelines' customers, producers and other
non-pipeline natural gas merchants of open and nondiscriminatory access to the
pipelines' transportation, storage and related services. This restructuring has
occurred over several years, culminating in 1992 with FERC's issuance of Order
No. 636, which caused all interstate pipelines to restructure their services
along open access principles, commencing with the 1993-1994 winter heating
season. In addition to its industry-wide orders such as Order No. 636, numerous
individual pipeline orders were issued in highly contested proceedings. As a
result, numerous appeals of these orders are now pending on appeal, and Pennzoil
cannot predict what action the reviewing courts or FERC may take on these
matters. Under the
 
                                       13
<PAGE>   15
 
current arrangements, however, the marketing flexibility of non-pipeline natural
gas merchants such as Pennzoil has been significantly enhanced.
 
     PETROLEUM PRICE CONTROL AND ALLOCATION LAWS. From time to time, the federal
government has imposed allocation and price controls upon firms engaged in
marketing crude oil and other petroleum products. However, since the 1981
lifting of federal price controls, sales of crude oil and other petroleum
products can be made at market prices.
 
     FEDERAL AND STATE PRODUCTION REGULATIONS.  Pennzoil's oil and gas
exploration and production operations are subject to various types of regulation
at the federal, state and local levels. Federal regulation of Pennzoil's
offshore Gulf of Mexico leases is accomplished by the Minerals Management
Service of the Department of the Interior ("MMS"). The FERC also has
jurisdiction over certain offshore activities pursuant to the Outer Continental
Shelf Lands Act. State regulation typically includes requiring drilling permits
and the maintenance of bonds in order to drill or operate wells; the regulation
of the location of wells, the method of drilling and casing of wells and the
surface use and restoration of properties upon which wells are drilled; and the
plugging and abandoning of wells. Pennzoil's operations are also subject to
various conservation regulations, including regulation of the size of drilling
and spacing units or proration units, the density of wells that may be drilled
in a given area and the unitization or pooling of oil and gas properties. In
this regard, some states allow the forced pooling or integration of lands and
leases. In addition, state conservation laws establish maximum rates of
production from oil and gas wells, generally prohibit the venting or flaring of
gas and impose certain requirements regarding the ratability of production. The
effect of these regulations may be to limit the amounts of crude oil, condensate
and natural gas Pennzoil can produce from its wells and the number of wells or
the locations at which Pennzoil can drill.
 
     ENVIRONMENTAL MATTERS.  Pennzoil's operations in the United States are
subject to numerous federal, state and local laws and regulations controlling
the discharge of materials into the environment or otherwise relating to the
protection of the environment and human health and safety.
 
     The 1990 Amendments to the federal Clean Air Act require, among other
things, more stringent controls on industrial plants in areas of high air
pollution, a tightening of fuel and emission standards for motor vehicles
(including certain requirements to use reformulated gasoline) and the imposition
by the Environmental Protection Agency ("EPA") of restrictions on the emissions
of hazardous air pollutants. While the precise effect of the Clean Air Act
Amendments on Pennzoil and other industrial companies is uncertain because most
of the Act's requirements will be implemented through EPA regulations to be
issued over a period of years, it is likely that the programs governing
hazardous air pollutants and auto fuels and emissions will require changes in
procedures and equipment in certain of Pennzoil's operations that could impose
substantial costs on Pennzoil. For example, in 1993, Pennzoil was required to
incur capital expenditures of $26.6 million for a diesel desulfurization and
dewaxing project at its Atlas refinery in Shreveport, Louisiana.
 
     The U.S. Oil Pollution Act of 1990 ("OPA '90") imposes a variety of
requirements on "responsible parties" (which can include Pennzoil or its
subsidiaries) related to the prevention of oil spills and liability for damages
resulting from such spills. OPA '90 also imposes the obligation on responsible
parties to demonstrate certain levels of financial responsibility. The effect of
OPA '90 on Pennzoil and other offshore oil and gas operators is uncertain
because the MMS has not yet finalized implementing regulations. Pennzoil cannot
predict the final form of the financial responsibility regulations that will be
adopted by the MMS, but such regulations have the potential to result in the
imposition of substantial costs on Pennzoil.
 
     Pennzoil is also subject to certain laws and regulations relating to
environmental remediation activities associated with past operations, such as
the Comprehensive Environmental Response, Compensation, and Liability Act, the
Resource Conservation and Recovery Act and similar state statutes. In response
to liabilities associated with these activities, accruals have been established
when reasonable estimates are possible. Pennzoil adjusts the accruals when new
remediation responsibilities are discovered and probable costs become estimable,
or when current remediation estimates must be adjusted to reflect new
information.
 
     Pennzoil's assessment of the potential impact of these environmental laws
is subject to uncertainty due to the difficult process of estimating and
refining remediation costs that are subject to ongoing and evolving
 
                                       14
<PAGE>   16
 
change. Initial estimates of remediation costs reflect a broad-based analysis of
site conditions and potential environmental and human health impacts derived
from preliminary site investigations (including soil and water analysis,
migration pathways and potential risk). Later changes in these initial estimates
may be based on additional site investigations, completion of feasibility
studies (comparing and selecting from among various remediation methods and
technologies) and risk assessments (determining the degree of current and future
risk to the environment and human health, based on current scientific and
regulatory criteria) and finally the actual implementation of the remediation
plan. This process occurs over relatively long periods of time and is influenced
by regulatory and community approval processes and subject to the ongoing
development of remediation technologies. Pennzoil's assessment analysis takes
into account the state of the process each site is in at the time of estimation,
the degree of uncertainty surrounding the estimates for each phase of
remediation and other site specific factors.
 
     Capital outlays of approximately $87.2 million have been made by Pennzoil
since January 1992 with respect to environmental protection. Capital
expenditures for environmental control facilities are currently expected to be
approximately $33 million in 1995. Reference is made to "Management's Discussion
and Analysis of Financial Condition and Results of Operations -- Capital
Resources and Liquidity -- Environmental Matters" for additional information.
 
     FRANCHISEE MATTERS. Jiffy Lube is subject to, and devotes substantial
efforts to compliance with, a variety of federal and state laws governing
franchise sales and marketing and franchise trade practices. Although the
regulatory environment differs by state, applicable laws and regulations
generally require disclosure of business information in connection with the sale
of franchises. Certain state regulations also affect the ability of the
franchisor to revoke or refuse to renew a franchise. Jiffy Lube seeks to comply
with applicable regulatory requirements. However, given the scope of Jiffy
Lube's business and the nature of franchise regulations, compliance problems can
be encountered from time to time.
 
ITEM 3. LEGAL PROCEEDINGS.
 
     (A) CURTAILMENT DAMAGE ACTIONS. Reference is made to Note 8 of Notes to
Consolidated Financial Statements for information regarding a lawsuit in which
Pennzoil has been joined as a defendant for damages allegedly caused by
curtailment of deliveries of gas by United Gas Pipe Line Company in 1974, a
former Pennzoil subsidiary, to its customers.
 
     (B) ENVIRONMENTAL MATTERS. In June 1994, Pennzoil received an
Administrative Complaint from the EPA alleging violation of the Superfund
Amendments and Reauthorization Act in connection with reporting requirements
under this statute, and the EPA regulations relating thereto, with respect to
Pennzoil's refinery in Roosevelt, Utah. The complaint seeks civil penalties of
$329,000. Pennzoil intends to vigorously contest both the alleged liability and
the amount of the proposed penalty. In July 1994, the West Virginia Division of
Environmental Protection opened negotiations with Pennzoil and Pennzoil's
indirect subsidiary Eureka Pipe Line Company ("Eureka") for a consent order
addressing numerous environmental matters relating to operations of Pennzoil and
Eureka. As currently proposed by the state agency, the consent order would
require Eureka to undertake environmental remediation at several locations and
would impose civil penalties of approximately $1.5 million. Pennzoil and Eureka
are investigating the state's position, but currently intend to vigorously
contest many of the state's claims and the amount of any civil penalty assessed.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.
 
     No matter was submitted during the fourth quarter of 1994 to a vote of
security holders.

     the new requirements of SFAS No. 106, "Employers' Accounting for
     Postretirement Benefits Other Than Pensions," effective as of January 1,
     1991. Pennzoil recorded a charge of $49.0 million ($74.2 million before
     tax), or $1.21 per share, in 1991 to reflect the cumulative effect of the
     change in accounting principle for periods prior to 1991.

RESULTS OF OPERATIONS
 
     A net loss of $288.7 million, or $6.27 per share, was recorded for 1994
compared with net income of $141.9 million, or $3.36 per share, for 1993 and
$128.2 million, or $3.16 per share, for 1992. Results for 1994 include net
charges of $210.4 million ($388.2 million before tax), or $4.57 per share,
associated with the
 
                                       18

settlement of a dispute with the Internal Revenue Service ("IRS") relating to a
proposed tax deficiency based on an audit of Pennzoil's 1988 federal income tax
return. Reference is made to "-- Capital Resources and Liquidity" and Note 8 of
Notes to Consolidated Financial Statements for additional information.
 
     Results of operations for 1994 also include a $21.1 million ($32.5 million
before tax), or $.46 per share, charge associated with the cessation of crude
oil processing at Pennzoil's Roosevelt, Utah refinery, a $32.6 million ($50.2
million before tax), or $.71 per share, charge in connection with the agreement
providing for the sale by Pennzoil to Freeport-McMoRan Resource Partners,
Limited Partnership ("Freeport-McMoRan") of substantially all the domestic
assets of Pennzoil's sulphur segment, and a $9.9 million ($15.2 million before
tax), or $.22 per share, charge to reflect adjustments of recorded values of
certain real estate properties. Reference is made to "-- Motor Oil & Refined
Products", "-- Sulphur" and "-- Other", respectively, for additional
information.
 
     Effective January 1, 1994, Pennzoil changed its method of accounting for
postemployment benefit costs by adopting the new requirements of Statement of
Financial Accounting Standards ("SFAS") No. 112, "Employers' Accounting for
Postemployment Benefits." As a result, Pennzoil recorded a charge of $4.9
million ($7.6 million before tax), or $.11 per share, as of January 1, 1994, to
reflect the cumulative effect of change in accounting principle for the periods
prior to 1994.
 
     In November 1993, Pennzoil sold 8,158,582 shares of Chevron Corporation
("Chevron") common stock in a block trade on the New York Stock Exchange
("NYSE") for a net price of $88.38 per share. The sale resulted in a net
realized gain of $137.0 million ($171.6 million before tax), or $3.25 per share.
Reference is made to "-- Capital Resources and Liquidity" for additional
information.
 
     In September 1993, Pennzoil called for redemption an aggregate of $292.5
million principal amount of indebtedness. The premiums and related unamortized
discount and debt issue costs relating to these redemptions resulted in an
extraordinary charge of $13.7 million ($21.1 million before tax), or $.32 per
share, in 1993. In June 1993, Pennzoil called for redemption $96.1 million
principal amount of indebtedness (which redemption occurred in July 1993). The
premiums and related unamortized discount and debt issue costs relating to these
redemptions resulted in an extraordinary charge of $4.7 million ($7.2 million
before tax), or $.11 per share, in 1993.
 
     In August 1993, the Omnibus Budget Reconciliation Act of 1993 was enacted,
establishing a new 35% corporate income tax rate effective January 1, 1993. As a
result of the increase in the marginal income tax rate and other tax law
changes, Pennzoil recorded a one-time, non-cash charge of $16.0 million, or $.38
per share, in 1993 to adjust its deferred income tax liabilities and assets for
the effect of the change in income tax rates.
 
     In December 1992, Pennzoil announced its decision to change its method of
accounting for income taxes by adopting the new requirements of SFAS No. 109,
"Accounting for Income Taxes," effective as of January 1, 1992. As a result,
Pennzoil recognized an increase to net income of $119.1 million in 1992. Of this
amount, $115.7 million, or $2.85 per share, was reported as the one-time
cumulative effect on prior year results. The remaining $3.4 million, or $.08 per
share, reflected the impact of adoption of this standard on 1992 income from
continuing operations. Reference is made to Note 2 of Notes to Consolidated
Financial Statements for additional information.
 
     In December 1992, Pennzoil sold in initial public offerings all its shares
of capital stock of Purolator Products Company ("Purolator"). Pennzoil recorded
a net gain on the disposition of Purolator of $1.5 million, or $.04 per share,
in 1992. Reference is made to "-- Discontinued Operations" and Note 11 of Notes
to Consolidated Financial Statements for additional information.
 
     In December 1992, Pennzoil called for redemption $272.9 million principal
amount of indebtedness (which redemption occurred in February 1993). As of
December 31, 1992, this indebtedness was defeased by placing funds required for
the redemption with the trustee for the indebtedness. As a result, the funds
deposited with the trustee for the redemption of the debentures and the
principal amount of the indebtedness were not reflected in Pennzoil's
consolidated balance sheet at December 31, 1992. The premiums and related
unamortized discount and debt issue costs relating to this redemption resulted
in an extraordinary charge of $16.6 million ($25.2 million before tax), or $.41
per share, in 1992.

     Investment and other income, net, for 1994 and 1992 primarily represents
dividend income from Pennzoil's investment in Chevron common stock. Investment
and other income, net, for 1993 primarily represents a pretax gain of $171.6
million from Pennzoil's sale of 8,158,582 shares of Chevron common stock and
dividend income from Pennzoil's investment in Chevron common stock. Pennzoil
beneficially owned 18,071,036 shares of Chevron common stock as of December 31,
1994, after giving effect to a "two-for-one" split of Chevron common stock in
June 1994. The shares of Chevron common stock beneficially owned by Pennzoil are
classified as non-current marketable securities and other investments in the
accompanying consolidated balance sheet. Reference is made to "-- Capital
Resources and Liquidity" for additional information.
 
OIL AND GAS
 
     The oil and gas segment recorded an operating loss of $4.9 million in 1994,
compared with operating income of $159.2 million in 1993 and $134.7 million in
1992. The reduction in operating income was attributable to weak oil and gas
prices, increased depreciation, depletion and amortization of $93.9 million
related to the settlement of a tax dispute with the IRS, and other nonrecurring
net charges totaling $36.8 million.
 
     In October 1992, Pennzoil completed a tax-free transaction with Chevron,
pursuant to which Pennzoil exchanged 15,750,000 shares of Chevron common stock
beneficially owned by Pennzoil for all the capital stock of Pennzoil Petroleum
Company ("Pennzoil Petroleum"), which owned Gulf of Mexico, Gulf Coast, Permian
Basin and other domestic oil and gas producing properties. The exchange of stock
was accounted for using the purchase method of accounting, and the results of
operations of Pennzoil Petroleum subsequent to October 30, 1992 have been
included in Pennzoil's oil and gas segment results. Included in the assets of
Pennzoil Petroleum at the time of the transfer to Pennzoil was $57.4 million in
cash contributed by Chevron to Pennzoil Petroleum immediately prior to closing,
representing the net cash flow from Pennzoil Petroleum's operations during the
four-month period between the "effective date" and the closing date of the
transaction, after reduction as a result of nonrecurring closing adjustments of
approximately $11 million. As a result of an audit completed during 1993,
Chevron contributed an additional $9.9 million in cash to Pennzoil Petroleum in
1993, representing an adjustment to the initial $57.4 million cash contribution
made by Chevron to Pennzoil Petroleum prior to closing. This additional
contribution from Chevron was accounted for as an adjustment to the original
purchase price of Pennzoil Petroleum. As a result of an audit conducted during
1994, Chevron contributed an additional $6.8 million in cash to Pennzoil
Petroleum in 1994, representing post-closing adjustments related to the
acquisition. Reference is made to Note 10 of Notes to Consolidated Financial
Statements for additional information.
 
     As a result of the IRS settlement in October 1994, Pennzoil increased the
balance of its investment in Pennzoil Petroleum capital stock for financial
reporting purposes and, therefore, the carrying value of Pennzoil Petroleum's
oil and gas properties by $390.3 million, and such increased investment resulted
in a $93.9 million increase in depreciation, depletion and amortization expense
recognized in October 1994 relating to Pennzoil Petroleum's oil and gas
properties from the date of the acquisition of Pennzoil Petroleum to the date of
the IRS settlement. These adjustments resulted in a net increase in property,
plant and equipment of $296.4 million as of September 30, 1994, while interest
charges and depreciation, depletion and amortization expense adjustments related
to the IRS settlement reduced Pennzoil's 1994 pretax income by $388.2 million.
In addition, oil and gas segment earnings will be reduced in future periods by
comparably higher depreciation, depletion and amortization expense as a result
of the increase in the investment in Pennzoil Petroleum's oil and gas
properties. Reference is made to Note 8 of Notes to Consolidated Financial
Statements for additional information.
 
     Oil and gas production volumes increased approximately 10% for 1994
compared to 1993, despite a reduction in production associated with the 1993
sale of a net 60 Bcf of proved natural gas reserves and a net 3 million barrels
of proved oil reserves. The increase in production volumes was primarily as a
result of accelerated Gulf of Mexico drilling and the addition of the oil and
gas properties of Co-enerco Resources Ltd. ("Co-enerco"). Natural gas produced
for sale in 1994 was 716,962 Mcf per day, compared with 649,399 Mcf per day and
447,561 Mcf per day in 1993 and 1992, respectively. Natural gas prices averaged
$1.79 per Mcf in
 
                                       20
<PAGE>   22
 
1994 compared to $2.04 per Mcf in 1993 and $1.81 per Mcf in 1992. Liquids
volumes in 1994 were 68,709 barrels per day, compared to 64,273 and 39,462
barrels per day in 1993 and 1992, respectively. The average liquids price
received in 1994 dropped to $13.74 per barrel, compared with $14.90 per barrel
in 1993 and $16.95 per barrel in 1992.
 
     The results of operations from Pennzoil's oil and gas segment are subject
to volatility resulting from changes in crude oil and natural gas prices.
Pennzoil has used in the past, and may use in the future, a limited price-risk
management strategy to provide protection against temporary declines in domestic
natural gas prices. To date, these price-risk management activities have
encompassed no more than 3% of Pennzoil's total annual natural gas production.
 
     In February 1995, Pennzoil and Brooklyn Union Gas Co. announced that their
subsidiaries, Pennzoil Gas Marketing Company and BRING Gas Services Corp., would
form a 50-50 gas marketing joint venture. Pennzoil currently expects to
contribute approximately $3 million in cash to the venture and to commit
substantially all of its natural gas production from the continental U.S. to be
marketed through the venture.
 
     Pennzoil disposed of approximately 90 producing oil and gas fields in 1994,
continuing its asset highgrading program begun in 1992, and decreasing the
number of producing fields in which Pennzoil had an interest from approximately
800 in early 1993 to approximately 400 at the end of 1994. Reference is made to
"-- Capital Resources and Liquidity -- Assessment of Oil and Gas Properties" for
additional information.
 
     Expenses associated with exploration activities in 1994 were $61.0 million
compared with $70.7 million in 1993 and $11.7 million in 1992. Exploration
expenses in 1994 included a $9.6 million charge for impairments of unproved
property costs and an increase in geological and geophysical expenses of $7.2
million over 1993 associated with an increase in Pennzoil's domestic exploration
and development activity and the continuing assessment of its domestic oil and
gas properties. In the early stages of this assessment, Pennzoil curtailed
domestic exploration activity and, as a result, reduced its 1992 capital budget
related to both exploration and development activity and geological and
geophysical expenses. As this assessment has progressed, more exploration and
development activity has occurred in and around core areas.
 
     Operating results for 1994 included a charge of $24.3 million for the
write-down of an investment in a Siberian drilling partnership and $13.8 million
in charges associated with the impending disposition of other various non-core
assets.
 
     Depreciation, depletion and amortization expense in 1994 and 1993 include
charges of $29.8 and $17.7 million, respectively, to increase an impairment
reserve originally established in 1988 related to Pennzoil's net investment in
offshore California producing properties. Generally lower offshore California
oil prices, a reassessment of remaining reserves and revisions to other
projected economic parameters led Pennzoil to determine that additional
impairments were necessary.
 
     In June 1994, Pennzoil Canada, Inc. ("Pennzoil Canada"), an indirect wholly
owned subsidiary of Pennzoil, acquired Co-enerco, a Canadian oil and gas
exploration and production company operating in Alberta, northeastern British
Columbia and southeastern Saskatchewan. Pennzoil Canada paid $230.9 million in
cash in connection with the acquisition of Co-enerco and the repayment of
Co-enerco's outstanding bank debt, which was financed primarily through two
credit facilities. The acquisition of Co-enerco was accounted for using the
purchase method of accounting, and the results of operations of Co-enerco
subsequent to June 30, 1994 have been included in Pennzoil's oil and gas segment
results. Reference is made to Notes 3 and 10 of Notes to Consolidated Financial

     In July 1994, Pennzoil Qatar, Inc. ("Pennzoil Qatar"), an indirect wholly
owned subsidiary of Pennzoil, was awarded the rights to explore acreage of Block
8 offshore Qatar. The block is located 50 miles from shore in the Arabian Gulf
and is adjacent to three large producing oil fields. Under the production
sharing agreement, Pennzoil Qatar has committed to a seismic acquisition and
drilling program over the next four years. Seismic acquisition is planned for
the second quarter of 1995; drilling will begin late this year or early in 1996,
with four wells planned over the next several years.

     In September 1994, the State Oil Company of the Azerbaijan Republic
("SOCAR") and a consortium of foreign oil companies, which includes Pennzoil,
signed an oil production sharing contract for development of the Azeri, Chirag
and a deep-water portion of the Guneshli fields in the Caspian Sea. The contract
was ratified by the National Parliament of the Republic of Azerbaijan in
November 1994 and was made effective in December 1994. Aggregate capital
investment for all the participants in the consortium is estimated to be between
$7 and $8 billion over the 30-year life of this project to develop an estimated
4 billion barrels of recoverable reserves. Pennzoil's 9.82% share has the
potential to add net reserves estimated in the range of 300 million barrels once
the area is developed. The contract includes a $300 million bonus to be paid by
the consortium to the government of Azerbaijan in a phased manner over the life
of the project. The bonus payment is payable in three installments. The first
bonus payment made by the consortium was equal to 50% of the total bonus.
Pennzoil's proportionate share was $17.8 million, of which $11.9 million was
paid in cash and $5.9 million was credited toward Pennzoil's prior investment in
a gas utilization project in Azerbaijan. The second bonus payment, equal to 25%
of the total bonus, will be due 30 days from the date when production in the
contract area reaches an average rate of 40,000 barrels of crude oil per day and
is sustained for a period of 60 days. The remaining bonus payment will be due
within 30 days from the date when crude oil has been exported from the main
export pipeline for a sustained period of 60 days.
 
     In November 1994, Pennzoil Egypt, Inc., an indirect wholly owned subsidiary
of Pennzoil, and its Spanish partner, Repsol Exploracion Egypto S.A., were
selected to explore the Southeast Gulf of Suez Block offshore Egypt. The block,
which is approximately the size of 44 Gulf of Mexico blocks, surrounds the Shoab
Ali oil field, which has significant oil reserves in place. The agreement
requires approval by the Egyptian Oil Ministry, cabinet and parliament. The
agreement calls for acquisition of 3-D seismic data and the drilling of one well
over the next two years following final approval of the agreement.
 
     Capital expenditures for the oil and gas segment in 1994 were $399.5
million, excluding expenditures related to Pennzoil's acquisition of Co-enerco,
compared to $360.5 million in 1993, and $93.8 million in 1992, excluding
expenditures related to Pennzoil's acquisition of Pennzoil Petroleum. Total
capital expenditures for this segment in 1995 are estimated to be $334.2
million. Reference is made to "-- Capital Resources and Liquidity" for
additional information.
 
MOTOR OIL & REFINED PRODUCTS
 
     Operating income in 1994 for this segment was $41.8 million, compared with
$90.0 million in 1993 and $77.9 million in 1992. Lower earnings in the
manufacturing division in 1994 resulted primarily from a third quarter charge of
approximately $32.5 million associated with the cessation of crude oil
processing at Pennzoil's Roosevelt, Utah refinery. Total processed volume at the
refineries of 58,703 barrels per day in 1994 was 519 barrels per day lower than
1993 but 248 barrels per day higher than 1992. Also contributing to lower
earnings in the manufacturing division were expenses incurred related to the
start-up of a joint venture project with Conoco, Inc. ("Conoco") described
below. Lower earnings in the domestic marketing division primarily resulted from
lower GUMOUT(R) sales volumes and margins and higher advertising expense,
partially offset by higher revenues from all other products. Domestic motor oil
volumes were about 1% higher than 1993 and 1992. Domestic motor oil margins
increased approximately 2% over 1993 margins and approximately 8% over 1992
margins. These margin increases were primarily the result of lower average crude
oil prices in 1994 versus 1993 and 1992. Higher earnings in the international
marketing division resulted primarily from increased revenues partially offset
by higher advertising and selling expenditures. Total international motor oil
and other lubricating product sales volumes, including those sold through
licensees and joint ventures, increased 36% when compared to 1993 and 70% when
compared to 1992.
 
     In June 1994, Conoco and Pennzoil agreed to carry out a joint venture
project at Conoco's refinery in Lake Charles, Louisiana. Operating through a
50-50 joint venture, the companies will construct a new, state-of-the-art lube
oil hydrocracker facility estimated to cost approximately $500 million, which is
expected to be funded with project financing. The facility will produce more
than 16,000 barrels per day of high-quality base oils, the base ingredient in
finished lubricants. Site preparation began in the third quarter of 1994, and
the facility is expected to be completed in early 1997. Conoco is acting as
construction manager and operator of the plant with support positions staffed by
both companies.

     In September 1994, Pennzoil and the Polymers Division of Petrolite
Corporation ("Petrolite") agreed in principle to form the BARECO(R) Products
Company, a 50-50 partnership aimed at providing a broad line of wax products to
domestic and international purchasers of paraffin, microcrystalline and related
synthetic waxes. Pennzoil will transport partially refined feedstock from Utah
to its Rouseville refinery, which will produce paraffinic waxes and related
products. The new wax products, along with certain waxes from Petrolite and
existing wax products from Pennzoil's Atlas and Rouseville refineries, will be
sold through the partnership. More than $23 million will be invested by Pennzoil
at its Rouseville refinery and its packaging plant in nearby Reno, Pennsylvania
in connection with this venture. Marketing will begin in April 1995.
 
     Capital expenditures for the motor oil and refined products segment were
$40.4 million in 1994, $71.5 million in 1993 and $35.8 million in 1992. The 1993
expenditures included $26.6 million for a diesel desulphurization and dewaxing
project at the Atlas refinery in Shreveport, Louisiana, which was required to
meet requirements promulgated under the 1990 Amendments to the federal Clean Air
Act. Also included were expenditures of $6.3 million for a feasibility study for
the base oil plant joint venture with Conoco and $4.8 million for the
acquisition of property, plant and equipment of a blending plant in Spain
(acquired in the first quarter of 1993). Capital expenditures for 1994 were
primarily at a level to maintain operations. Total capital expenditures for this
segment in 1995 are estimated to be $120.7 million. The 1995 capital budget
includes $41.3 million to begin construction of a refinery complex designed to
convert the Atlas refinery's lube oil by-products into clean burning gasoline
and diesel fuels. This upgrade project will allow Atlas to significantly
diversify its production capabilities and to realize higher profits from
by-products, which are currently sold at low values. The 1995 capital budget
also includes $20.5 million to provide for manufacturing facilities at the
Rouseville refinery and the Reno packaging plant to enable production of
additional waxes in connection with the Petrolite joint venture.
 
FRANCHISE OPERATIONS
 
     The franchise operations segment, operating through Pennzoil's wholly owned
subsidiary Jiffy Lube International, Inc. ("Jiffy Lube"), recorded operating
income of $2.8 million during 1994, compared to operating losses of $17.6
million in 1993 and $13.4 million in 1992. Operating income in 1994 improved
significantly as a result of improvements in company center revenues and reduced
operating costs. Excluding legal settlement charges, selling, general and
administrative costs were down approximately $1.3 million. Operating results for
1994 include charges of $8.2 million for reserves for identified self-insured
claims, estimated environmental remediation costs, various litigation settlement
charges and other miscellaneous items. As of December 31, 1994, Jiffy Lube
operated 426 company-owned service centers.
 
     Operating results for 1993 included a charge of $10.0 million for estimated
costs associated with centers that Jiffy Lube had decided to eliminate. Jiffy
Lube had determined that these centers were not viable as company-operated
centers and had been unsuccessful in subleasing many of these centers for
alternative uses. This provision for estimated costs takes into consideration
the present value of future lease obligations related to operating leases (less
estimated sublease rental revenue of existing subleases) and the estimated fair
value of land, buildings, leaseholds and leasehold improvements. Additionally,
1993 results included approximately $12.7 million for the settlement of certain
litigation, estimated environmental costs and write-downs of other individually
insignificant investments to reflect Jiffy Lube's estimate of the net
realizability of those investments. Operating results in 1992 included increased
selling and administrative expenses of $6.8 million incurred in connection with
the settlement of certain litigation and increased start-up expenses of $2.6
million incurred in association with the development and installation of a new
point-of-sale system.
 
     Systemwide service center sales reported to Jiffy Lube for the year ended
December 31, 1994 increased $68.1 million, or approximately 12.6%, to $607.5
million, compared with the prior year, and increased $106.9 million, or
approximately 21.4%, compared with 1992. Average ticket prices increased to
$34.09 for the year ended December 31, 1994, compared with $33.60 and $33.23 for
the years ended December 31, 1993 and 1992, respectively.
 
     During the year ended December 31, 1994, Jiffy Lube acquired 22 centers
with estimated values of $5.2 million and real estate with estimated values of
$1.1 million, in exchange for cash of $5.2 million,
 
                                       23
<PAGE>   25
 
forgiveness of amounts due Jiffy Lube of $1.1 million, liabilities and debt
assumed of $.6 million and 4 centers with a net book value of $.3 million.
During the year ended December 31, 1993, Jiffy Lube acquired 70 centers with
estimated values of $15.8 million and real estate with estimated values of $.9
million in exchange for cash of $12.2 million, forgiveness of amounts due Jiffy
Lube of $.9 million, liabilities assumed of $.5 million, debt assumed of $.4
million and real estate valued at $1.6 million. During the year ended December
31, 1992, Jiffy Lube acquired 104 service centers with estimated values of $29.7
million in exchange for cash of $16.7 million, forgiveness of amounts due Jiffy
Lube of $2.8 million, liabilities assumed of $8.7 million and debt issued of
$1.5 million.
 
     Capital expenditures for the franchise operations segment were $18.9
million in 1994, compared to $21.7 million and $25.8 million in 1993 and 1992,
respectively. Capital expenditures for 1995 are estimated to be approximately
$48.8 million.
 
SULPHUR
 
     In October 1994, Pennzoil entered into an agreement with Freeport-McMoRan
providing for the sale by Pennzoil to Freeport-McMoRan of substantially all the
domestic assets of Pennzoil's sulphur segment. The transaction was completed in
January 1995. Pennzoil continues to own and operate its Antwerp, Belgium sulphur
terminal and the related international sulphur business. As consideration under
the agreement, Freeport-McMoRan assumed certain liabilities of Pennzoil relating
to or arising out of the business of Pennzoil's sulphur segment, and Pennzoil
will be entitled to receive a series of quarterly installment payments from
Freeport-McMoRan for periods through December 31, 2014, subject to the
prevailing market price of sulphur. The installment payments, recorded at their
estimated fair value of $22.5 million as of September 30, 1994, may be
terminated earlier by Freeport-McMoRan (through the exercise of a call option
providing for a $65 million payment to Pennzoil), or by Pennzoil (through the
exercise of a put option providing for a $10 million payment to Pennzoil).
Neither the call option nor the put option may be exercised prior to January
1999. In connection with this transaction, Pennzoil's sulphur segment recorded a
charge to depreciation, depletion and amortization expense of $50.2 million in
September 1994.
 
     Excluding the $50.2 million pretax charge, the sulphur segment recorded an
operating loss of $7.2 million in 1994 compared to a loss of $20.8 million in
1993 and operating income of $1.0 million in 1992. The average Green Markets
Tampa Recovered Contract Price range for sulphur in 1994 had a mid-point of
$57.00 per long ton in 1994 compared to a 1993 mid-point of $64.00 per long ton
and a 1992 mid-point of $86.50 per long ton. Intense competition in the domestic
market has pushed sulphur prices down, primarily because of aggressive marketing
by U.S. producers. Partially offsetting these lower sulphur prices in 1994 were
lower unit costs due to reduced workforce expenses and reduced gas and water
treatment costs at the Culberson mine.
 
     During 1994, sulphur sales volumes were 1.2 million long tons compared to
1.1 million long tons in 1993 and 1.7 million long tons in 1992. The lower level
of sales volumes in 1994 and 1993 were primarily due to reduced market share
resulting from lower priced imports from Canada and increased recovered
production domestically.
 
OTHER
 
     Other operating income in 1994 was $55.6 million, compared to $253.7
million in 1993 and $88.2 million in 1992. Other operating income for 1994
includes a $15.2 million charge to reflect adjustment of recorded values of
certain real estate properties. The higher level of other income in 1993 was
primarily due to the gains of $171.6 million on the sale of shares of Chevron
common stock and $10.5 million on the sale of shares of Pogo Producing Company
common stock. Dividend income on the Chevron common stock was $33.4 million for
1994, $60.2 million for 1993 and $95.7 million for 1992.

INTEREST CHARGES, NET
 
     Net interest expense for 1994 included interest charges of $294.3 million
associated with the IRS settlement. Reference is made to Note 8 of Notes to
Consolidated Financial Statements for additional information.
 
     Excluding the interest expense associated with the IRS settlement, interest
charges, net of interest capitalized for 1994, increased $2.8 million over 1993
levels and decreased $42.3 million from 1992 levels. The increase in interest
expense for 1994 was primarily due to increased borrowings at higher average
interest rates. The decrease in interest expense from 1992 levels is primarily
due to lower average interest rates.

DISCONTINUED OPERATIONS
 
     In October 1992, as a result of Pennzoil's conclusion that disposal of
Purolator's filtration products operations would enhance Pennzoil's efforts to
focus on its strategic businesses and to reduce indebtedness, Purolator filed a
registration statement pursuant to which Pennzoil offered to the public all
shares of Purolator stock held by Pennzoil. Accordingly, Purolator's net assets
and results of operations for all periods have been reclassified as discontinued
operations for financial reporting purposes. In December 1992, Pennzoil sold in
initial public offerings all its shares of capital stock of Purolator. The total
amount received by Pennzoil, prior to the payment of expenses, from the net
proceeds of the offerings and the repayment of indebtedness by Purolator was
$206.0 million. Pennzoil recorded a net gain on the disposition of Purolator
stock of $1.5 million ($20.0 million before tax loss), or $.04 per share, in
1992.
 
     Reference is made to "-- Capital Resources and Liquidity -- Environmental
Matters" and Note 8 of Notes to Consolidated Financial Statements for
information concerning an environmental indemnification agreement between
Pennzoil and Purolator entered into in connection with Pennzoil's disposition of
Purolator.
 
CAPITAL RESOURCES AND LIQUIDITY
 
     CASH FLOW. Pennzoil had cash and cash equivalents of $24.9 million and
$262.3 million at December 31, 1994 and 1993, respectively. Pennzoil's cash flow
from operating activities, excluding the cash payment made to the IRS for taxes
and interest in settlement of a dispute relating to a proposed tax deficiency
based on an
 
                                       25

audit of Pennzoil's 1988 federal income tax return, was $322.7 million for the
twelve months ended December 31, 1994. Reference is made to Note 8 of Notes to
Consolidated Financial Statements for additional information. Cash flow from
operating activities was $286.9 million for the twelve months ended December 31,
1993. Pennzoil used cash from operating activities, net proceeds from the sales
of marketable securities and proceeds from the sales of assets primarily for
payments relating to the IRS settlement ($556.0 million), capital expenditures
($473.3 million) and the payment of cash dividends ($138.1 million).
 
     INVESTMENT IN CHEVRON CORPORATION. Pennzoil beneficially owned 18,071,036
shares of Chevron common stock as of December 31, 1994, after giving effect to a
"two-for-one" stock split declared by Chevron in June 1994. None of the share or
per-share information related to Pennzoil's investment in Chevron common stock
prior to June 1994 has been adjusted to reflect the "two-for-one" stock split.
The current quarterly dividend rate on Chevron common stock is $.4625 per share.
At the current dividend rate, Pennzoil receives $33.4 million annually in
dividends on the 18,071,036 Chevron shares. All 18,071,036 shares of Chevron
common stock beneficially owned by Pennzoil have been deposited with exchange
agents for possible exchange for Pennzoil exchangeable debentures. See
"-- Exchangeable Debentures."
 
     In November 1993, Pennzoil sold 8,158,582 shares of Chevron common stock in
a block trade on the NYSE for a price of $89.00 per share before commissions
($88.38 per share net of commissions). The sale resulted in a net realized gain
of $137.0 million ($171.6 million before tax), or $3.25 per share. Reference is
made to Note 2 of Notes to Consolidated Financial Statements for additional
information.
 
     In October 1992, Pennzoil completed a tax-free transaction with Chevron,
pursuant to which Pennzoil exchanged 15,750,000 shares of Chevron common stock
beneficially owned by Pennzoil for all the capital stock of Pennzoil Petroleum,
which owned Gulf of Mexico, Gulf Coast, Permian Basin and other domestic oil and
gas producing properties. The exchange of stock was accounted for using the
purchase method of accounting, and the results of operations of Pennzoil
Petroleum subsequent to October 30, 1992 have been included in Pennzoil's oil
and gas segment results.
 
     EXCHANGEABLE DEBENTURES. In 1993, Pennzoil completed public offerings of
$402.5 million principal amount of its 6 1/2% Exchangeable Senior Debentures due
January 15, 2003 (the "6 1/2% Debentures") and $500.0 million principal amount
of its 4 3/4% Exchangeable Senior Debentures due October 1, 2003 (the "4 3/4%
Debentures"). The 6 1/2% Debentures and the 4 3/4% Debentures are exchangeable
at the option of the holders thereof at any time prior to maturity, unless
previously redeemed, for shares of Chevron common stock beneficially owned by
Pennzoil at exchange rates of 23.774 shares and 17.004 shares, respectively, per
$1,000 principal amount of the 6 1/2% Debentures and the 4 3/4% Debentures (the
equivalent of $42 1/16 per share and $58 13/16 per share, respectively), subject
to adjustment in certain events. In lieu of delivering certificates representing
shares of Chevron common stock in exchange for the 6 1/2% Debentures and the
4 3/4% Debentures, Pennzoil may, at its option, pay to any holder surrendering
the 6 1/2% Debentures and the 4 3/4% Debentures an amount in cash equal to the
market price of the shares for which the 6 1/2% Debentures and the 4 3/4%
Debentures are exchangeable. Pennzoil has deposited all 18,071,036 shares of
Chevron common stock beneficially owned by Pennzoil with exchange agents for
possible exchange for the 6 1/2% Debentures and the 4 3/4% Debentures.
 
     Under the instruments governing the 6 1/2% Debentures and the 4 3/4%
Debentures, Pennzoil may not pledge, mortgage, hypothecate or grant a security
interest in, or permit any mortgage, pledge, security interest or other lien
upon, the shares of Chevron common stock deposited with exchange agents and
deliverable in exchange for the 6 1/2% Debentures and the 4 3/4% Debentures.
Pennzoil may at any time obtain from the exchange agents or otherwise authorize
or direct the exchange agents to release all or part of the 18,071,036 shares of
Chevron common stock deposited with the exchange agents. However, in the event
Pennzoil obtains or otherwise releases any shares of Chevron common stock
subject to exchange, each holder of a 6 1/2% Debenture or a 4 3/4% Debenture
will generally have the right, at such holder's option, to require Pennzoil to
repurchase all or a portion of such holder's debentures at a premium.
 
     ASSESSMENT OF OIL AND GAS PROPERTIES. Pennzoil is continuing its assessment
of its domestic oil and gas properties and its related asset highgrading program
commenced in early 1992. The assessment has resulted in, and is expected to
continue to result in, the categorization of Pennzoil's oil and gas properties
into core and
 
                                       26
<PAGE>   28
 
noncore producing areas and core and noncore producing fields within core areas.
In the early stages of the assessment, Pennzoil curtailed domestic exploration
and development activity and, as a result, reduced its 1992 capital expenditures
for domestic exploration and development by approximately one-half, excluding
expenditures related to Pennzoil's acquisition of Pennzoil Petroleum. The
ongoing assessment now includes the properties added in October 1992 as a result
of the acquisition of Pennzoil Petroleum and the properties added in July 1994
as a result of the acquisition of Co-enerco, which have created additional core
areas and enhanced other core areas. As part of its asset highgrading program,
Pennzoil disposed of approximately $35 million of noncore properties and fields
during 1992. No significant gain or loss was realized as a result of these
dispositions. Pennzoil began 1993 with interests in approximately 800 producing
fields, owning small working interests and/or insignificant reserves in the
majority of these fields. In 1993, the asset highgrading program resulted in the
disposal of approximately 300 fields, representing less than 3% of the total
value of Pennzoil's proved oil and gas reserves. Pennzoil realized gains in 1993
of $34.9 million from these asset dispositions on total proceeds of $87.5
million. In addition, four asset exchanges were finalized during 1993 to
increase working interests in core Gulf of Mexico fields.
 
     Pennzoil disposed of approximately 90 producing oil and gas fields in 1994,
continuing its asset highgrading program begun in 1992, and decreasing the
number of producing fields in which Pennzoil had an interest to approximately
400 at the end of 1994. The fields disposed of in 1994 primarily consisted of
noncore properties in the Gulf of Mexico, Permian Basin, Mid-Continent and Gulf
Coast. Pennzoil realized gains in 1994 of $36.0 million from these asset
dispositions on total proceeds of $81.3 million. The 1994 asset dispositions in
the aggregate represented approximately 5% of Pennzoil's total oil and gas
production and approximately 3% of the total value of Pennzoil's proved oil and
gas reserves. If market conditions are favorable, Pennzoil intends to continue
the disposal of noncore properties during 1995 with the goal of retaining about
100 core fields in the United States by late 1995. These 100 core fields are
estimated to generate approximately 90% of Pennzoil's current cash flow and
contain most of Pennzoil's future reserve potential. In addition to dispositions
of producing fields, Pennzoil completed five exchanges of producing fields in
1994, representing approximately $26 million in assets, primarily in the Gulf of
Mexico and Permian Basin. After netting asset dispositions against acquisitions
and including the impact of the acquisition of Co-enerco and exchanges,
Pennzoil's asset highgrading program in 1994 added approximately 32 million
barrels of oil equivalent ("BOE") at a net cost of $149.7 million, for a reserve
replacement cost of $4.68 per BOE.
 
     CREDIT FACILITIES. In August 1994, Pennzoil entered into an amended and
restated credit facility with a group of banks that provides for up to $600
million of unsecured revolving credit borrowings through August 16, 1995, with
any outstanding borrowings on such date being converted into a term credit
facility terminating on September 1, 1996. Pennzoil has the option, subject to
the extension of additional credit by new or existing banks, of increasing the
size of the facility by $100 million. This amended and restated credit facility
replaces and supersedes the previous revolving credit facilities of Pennzoil.
Borrowings under the facility totaled $205.0 million at December 31, 1994.
 
     In June 1994, in connection with its acquisition of Co-enerco, Pennzoil
Canada established a Cdn. $260 million credit facility with a syndicate of
Canadian banks, the borrowings of which are guaranteed by Pennzoil. Also in June
1994, Pennzoil Canada established an additional Cdn. $40 million credit facility
with a Canadian bank, the borrowings of which are guaranteed by Pennzoil. These
facilities provide for borrowings through May 30, 1995, with any outstanding
borrowings on such date being converted into term credit facilities terminating
on May 30, 1996. Borrowings under these facilities can be made in any
combination of U.S. or Canadian dollars and totaled U.S. $185.0 million and U.S.
$10.0 million, respectively, as of December 31, 1994.
 
     In February 1995, Pennzoil's Board of Directors increased the limit on the
aggregate amount of commercial paper that Pennzoil may issue under its domestic
commercial paper program and/or its Euro-commercial paper program from $250.0
million to $500.0 million. Borrowings under Pennzoil's commercial paper
facilities totaled $243.9 million and $249.4 million at December 31, 1994 and
1993, respectively.
 
     Pennzoil has several short-term variable-rate credit arrangements with
certain banks. Pennzoil's Board of Directors has limited borrowings under these
credit arrangements to $200.0 million. Outstanding borrowings
 
                                       27
<PAGE>   29
 
totaled $93.3 million and $183.6 million at December 31, 1994 and 1993,
respectively. None of the banks under these credit arrangements has any
obligation to continue to extend credit after the maturities of outstanding
borrowings or to extend the maturities of any borrowings.
 
     SETTLEMENT OF IRS DISPUTE. Reference is made to Note 8 of Notes to
Consolidated Financial Statements for information concerning Pennzoil's
settlement in October 1994 of a dispute with the IRS relating to a proposed tax
deficiency based on an audit of Pennzoil's 1988 federal income tax return.
 
     CAPITAL EXPENDITURES. Total capital expenditures for 1994, excluding
expenditures related to Pennzoil's acquisition of Co-enerco, were $474.6
million, including $9.0 million of interest capitalized, representing a decrease
of $10.5 million from comparable 1993 capital expenditure levels.
 
     The table below summarizes the current 1995 capital budget by segment
compared with 1994 and 1993 capital expenditures, excluding expenditures related
to Pennzoil's acquisition of Co-enerco in 1994. The capital budget is reassessed
from time to time, and could, for example, be adjusted to reflect changes in oil
and gas prices and other economic factors.

     Pennzoil currently expects to generate funds for its budgeted 1995 capital
expenditures from a combination of some, or all, of the following: cash flows
from operations, the sale of noncore properties, borrowings under its credit
facilities and arrangements, available cash and proceeds from future debt
issuances.
 
     ENVIRONMENTAL MATTERS. Pennzoil continues to make capital and operating
expenditures relating to the environment, including expenditures associated with
its compliance with federal, state and local environmental regulations. As they
continue to evolve, environmental protection laws are expected to have an
increasing impact on Pennzoil's operations. In connection with pollution
abatement efforts related to current operations, Pennzoil made capital
expenditures of approximately $37 million in 1994 and $35 million in 1993. The
1993 expenditures included $26.6 million for a diesel desulphurization and
dewaxing project at the Atlas refinery in Shreveport, Louisiana, which was
required to meet requirements promulgated under the 1990 Amendments to the
federal Clean Air Act. Capital expenditures for environmental control facilities
are currently expected to be approximately $33 million in 1995. Pennzoil's
recurring operating expenditures relating to environmental compliance activities
are not material.
 
     Pennzoil is subject to certain laws and regulations relating to
environmental remediation activities associated with past operations, such as
the Comprehensive Environmental Response, Compensation, and Liability Act
("CERCLA"), the Resource Conservation and Recovery Act and similar state
statutes. In response to liabilities associated with these activities, accruals
have been established when reasonable estimates are possible. Such accruals
primarily include estimated costs associated with remediation. Pennzoil has not
used discounting in determining its accrued liabilities for environmental
remediation, and no claims for possible recovery from third party insurers or
other parties related to environmental costs have been recognized in Pennzoil's
consolidated financial statements. Pennzoil adjusts the accruals when new
remediation responsibilities are discovered and probable costs become estimable,
or when current remediation estimates must be adjusted to reflect new
information.
 
     Pennzoil's assessment of the potential impact of these environmental laws
is subject to uncertainty due to the difficult process of estimating and
refining remediation costs that are subject to ongoing and evolving
 
                                       28
<PAGE>   30
 
change. Initial estimates of remediation costs reflect a broad-based analysis of
site conditions and potential environmental and human health impacts derived
from preliminary site investigations (including soil and water analysis,
migration pathways and potential risk). Later changes in these initial estimates
may be based on additional site investigations, completion of feasibility
studies (comparing and selecting from among various remediation methods and
technologies) and risk assessments (determining the degree of current and future
risk to the environment and human health, based on current scientific and
regulatory criteria) and finally the actual implementation of the remediation
plan. This process occurs over relatively long periods of time and is influenced
by regulatory and community approval processes and subject to the ongoing
development of remediation technologies. Pennzoil's assessment analysis takes
into account the state of the process each site is in at the time of estimation,
the degree of uncertainty surrounding the estimates for each phase of
remediation and other site specific factors.
 
     In connection with Pennzoil's disposition of Purolator, Pennzoil and
Purolator entered into an indemnification agreement, pursuant to which Pennzoil
agreed to reimburse Purolator for the costs and expenses of certain
environmental remediation activities at a plant operated by Purolator in Elmira
Heights, New York, and certain environmental remediation activities, if any,
required at one other site located near the Elmira facility and a landfill site
located in Metamora, Michigan. Pennzoil had a reserve of $16.2 million and $16.3
million recorded with respect to its obligations under its indemnification
agreement with Purolator as of December 31, 1994 and 1993, respectively.
Reference is made to Notes 8 and 11 of Notes to Consolidated Financial
Statements for additional information.
 
     Certain of Pennzoil's subsidiaries are involved in matters in which it has
been alleged that such subsidiaries are potentially responsible parties ("PRPs")
under CERCLA or similar state legislation with respect to various waste disposal
areas owned or operated by third parties. In addition, certain of Pennzoil's
subsidiaries are involved in other environmental remediation activities,
including the removal, inspection and replacement, as necessary, of underground
storage tanks. As of December 31, 1994 and 1993, Pennzoil's consolidated balance
sheet included accrued liabilities for environmental remediation of $44.9
million and $33.1 million, respectively, which amounts include reserves with
respect to Pennzoil's obligations under its indemnification agreement with
Purolator referred to in the previous paragraph. Of these reserves, $8.8 million
and $4.8 million are reflected in the consolidated balance sheet as current
liabilities as of December 31, 1994 and 1993, respectively, and $36.1 million
and $28.3 million are reflected as other liabilities as of December 31, 1994 and
1993, respectively. Pennzoil does not currently believe there is a reasonable
possibility of incurring additional material costs in excess of the current
accruals recognized for such environmental remediation activities. With respect
to the sites in which Pennzoil subsidiaries are PRPs, Pennzoil's conclusion is
based in large part on (i) the availability of defenses to liability, including
the availability of the "petroleum exclusion" under CERCLA and similar state
laws, and/or (ii) Pennzoil's current belief that its share of wastes at a
particular site is or will be viewed by the Environmental Protection Agency or
other PRPs as being de minimis. As a result, Pennzoil's monetary exposure is not
expected to be material.
 
     OTHER MATTERS. Pennzoil does not currently consider the impact of inflation
to be significant in the businesses in which Pennzoil operates.

for a discussion of the impact that a recently issued accounting standard is
expected to have on Pennzoil's consolidated financial statements, when adopted.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Pennzoil Company:
 
     We have audited the accompanying consolidated balance sheet of Pennzoil
Company (a Delaware corporation) and subsidiaries as of December 31, 1994 and
1993, and the related consolidated statements of income, shareholders' equity
and cash flows for each of the three years in the period ended December 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 financial statements referred to above present fairly,
in all material respects, the financial position of Pennzoil Company and
subsidiaries as of December 31, 1994 and 1993, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1994, in conformity with generally accepted accounting principles.
 
     As discussed in Notes 1 and 6 to the Consolidated Financial Statements, the
Company changed its method of accounting for certain investments in debt and
equity securities and postemployment benefits as of January 1, 1994. Also, as
discussed in Note 2 to the Consolidated Financial Statements, as of January 1,
1992, the Company changed its method of accounting for income taxes.

                       PENNZOIL COMPANY AND SUBSIDIARIES
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES --
 
  Principles of Consolidation --
 
     The accompanying consolidated financial statements include all
majority-owned subsidiaries of Pennzoil Company ("Pennzoil"). All significant
intercompany accounts and transactions have been eliminated.
 
  Marketable Securities and Other Investments --
 
     Effective January 1, 1994, Pennzoil changed its method of accounting for
certain investments in debt and equity securities by adopting the requirements
of Statement of Financial Accounting Standards ("SFAS") No. 115, "Accounting for
Certain Investments in Debt and Equity Securities." This standard requires that,
except for debt securities classified as "held-to-maturity," investments in debt
and equity securities must be reported at fair value. As a result, Pennzoil's
investment in Chevron Corporation ("Chevron") common stock, which shares are
classified as "available for sale," is reported at fair value, with the
unrealized gain excluded from earnings and reported as a separate component of
shareholders' equity. As of January 1, 1994, Pennzoil beneficially owned
9,035,518 shares of Chevron common stock that were acquired at an average cost
of $67.36 per share. The fair market value for the shares of Chevron common
stock held by Pennzoil as of January 1, 1994 was $87.125 per share based on the
closing transaction price for Chevron shares reported on the New York Stock
Exchange ("NYSE") on December 31, 1993.
 
     After giving effect to a "two-for-one" split of Chevron common stock in
June 1994, Pennzoil beneficially owned 18,071,036 shares of Chevron common stock
as of December 31, 1994, acquired at an average cost of $33.68 per share.
 
     Realized gains on Pennzoil's remaining investment in Chevron common stock
are subject to the exchange rights of holders of Pennzoil's $402.5 million
outstanding principal amount of 6 1/2% Exchangeable Senior Debentures due
January 15, 2003 (the "6 1/2% Debentures") and $500.0 million outstanding
principal amount of 4 3/4% Exchangeable Senior Debentures due October 1, 2003
(the "4 3/4% Debentures"), all of which are exchangeable at the option of the
holders thereof for shares of Chevron common stock owned by Pennzoil. Reference
is made to Note 3 for additional information. The fair market value of the
shares of Chevron common stock held by Pennzoil as of December 31, 1994 was
$43.27 per share, based on the closing transaction price for Chevron common
stock reported on the NYSE on December 30, 1994 of $44.625 per share, reduced by
a $1.355 per share reserve for exchange rights relating to Pennzoil's
outstanding 6 1/2% Debentures and 4 3/4% Debentures.
 
     Adoption of SFAS No. 115 resulted in an increase in shareholders' equity of
$106.8 million as of January 1, 1994, representing the net unrealized gain
related to Pennzoil's investment in Chevron common stock. Prior year financial
statements have not been restated to reflect the new accounting method. As of
December 31, 1994, the net unrealized after-tax gain included in shareholders'
equity related to Pennzoil's investment in Chevron common stock was $112.7
million.

     In November 1993, Pennzoil sold 8,158,582 shares of Chevron common stock in
a block trade on the NYSE for a price of $89.00 per share before commissions
($88.38 per share net of commissions). The sale resulted in a net realized gain
of $137.0 million ($171.6 million before tax), or $3.25 per share. The cost of
the securities sold is based on the average cost of each security held at the
time of sale.
 
     Pennzoil's investments in debt securities are classified as
"held-to-maturity" based on Pennzoil's ability and intent to hold those
securities to maturity. Such securities are carried at cost, net of unamortized
premium or discount, if any, and consist solely of domestic commercial paper.
All of Pennzoil's "held-to-maturity" securities approximate their fair values
based on the relatively short maturities of those investments and on quoted
market prices, where such prices are available.
 
     Other income effects from marketable securities and other investments are
discussed under the caption "Investment and Other Income, Net" below.
 
  Investment and Other Income, Net --
 
     Other revenues, net of related expenses, are included in "Investment and

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
  Receivables --
 
     Current receivables include trade accounts and notes receivable and are net
of allowances for doubtful accounts of $10.5 million in 1994 and $10.0 million
in 1993. Long-term receivables consist of notes receivable and are net of
allowances for doubtful accounts of $.9 million in 1994 and $4.2 million in
1993.
 
     At December 31, 1994 and 1993, current receivables included notes
receivable of $10.7 million and $12.6 million, respectively. Other assets
included long-term notes receivable of $39.7 million and $44.7 million at
December 31, 1994 and 1993, respectively.
 
     In May 1993, the Financial Accounting Standards Board issued a new standard
on accounting by creditors for impairment of loans. This standard requires
certain impaired loans to be measured based on the present value of expected
future cash flows discounted at the loan's effective interest rate or, as a
practical expedient, at the loan's observable market price or the fair value of
the collateral if the loan is collateral dependent. Adoption of the standard by
Pennzoil is required no later than the first quarter of 1995, although earlier
implementation is permitted. Pennzoil currently expects to adopt the standard
effective January 1, 1995. Based on a preliminary review, Pennzoil does not
expect that adoption of the standard will have a material effect on its
financial condition or results of operations.
 
  Inventories --
 
     A majority of inventories is reported at cost using the last-in, first-out
("LIFO") method, which is lower than market. Substantially all other inventories
are reported at cost using the first-in, first-out method. Inventories valued on
the LIFO method totaled $122.2 million at December 31, 1994 and $131.2 million
at December 31, 1993. The current cost of LIFO inventories was approximately
$182.5 million and $178.8 million at December 31, 1994 and 1993, respectively.
 
  Oil and Gas Producing Activities and Depreciation, Depletion and
Amortization --
 
     Pennzoil follows the successful efforts method of accounting for oil and
gas operations. Under the successful efforts method, lease acquisition costs are
capitalized. Significant unproved properties are reviewed periodically on a
property-by-property basis to determine if there has been impairment of the
carrying value, with any such impairment charged currently to exploration
expense. All other unproved properties are generally aggregated and a portion of
such costs estimated to be nonproductive, based on historical experience, is
amortized on an average holding period basis.
 
     Exploratory drilling costs are capitalized pending determination of proved
reserves. If proved reserves are not discovered, the exploratory drilling costs
are expensed. Other exploration costs are also expensed. All development costs
are capitalized. Provision for depreciation, depletion and amortization is
determined on a field-by-field basis using the unit-of-production method.
Estimated costs of future dismantlement and abandonment of wells and production
platforms, net of salvage values, are accrued as part of depreciation, depletion
and amortization expense using the unit-of-production method; actual costs are
charged to accumulated depreciation, depletion and amortization. The carrying
amounts of proven properties are reviewed periodically and an impairment reserve
is provided as conditions warrant.
 
     Pennzoil follows the sales method of accounting for natural gas imbalances.
Under the sales method, revenue is recognized on all production delivered by
Pennzoil to its purchasers, regardless of Pennzoil's ownership interest in the
respective property. At December 31, 1994, Pennzoil's gas imbalance reflects a
net underproduced position of 14.4 billion cubic feet of gas. The company
expects to recover this imbalance from its co-owners through future production
or alternative arrangements.
 
     Sulphur properties were generally depreciated and depleted on the
unit-of-production method, except assets having an estimated life less than the
estimated life of the mineral deposits, which were depreciated on
 
                                      F-10

the straight-line method. In October 1994, Pennzoil entered into an agreement
with Freeport-McMoRan Resource Partners, Limited Partnership
("Freeport-McMoRan") providing for the sale by Pennzoil to Freeport-McMoRan of
substantially all the domestic assets of Pennzoil's sulphur segment. The
transaction was completed in January 1995. Reference is made to Note 10 for
additional information.
 
     All other properties are depreciated on straight-line or accelerated
methods in amounts calculated to allocate the cost of properties over their
estimated useful lives.
 
  Price Risk Management Activities --
 
     Pennzoil has a formal price risk management program that permits periodic
utilization of financial instruments to hedge a portion of the price risks
associated with fluctuations in crude oil and natural gas prices. Through
December 31, 1994, this program has been limited to the occasional use of swaps
with financial institutions and industry partners, which hedge the sales price
of natural gas. Gains and losses on these instruments are recognized in income
when the associated hedged commodities are sold.
 
     The results of Pennzoil's price risk management activities were not
material to its results of operations during the three-year period ended
December 31, 1994 or to its financial position as of that date.
 
  Environmental Expenditures --
 
     Environmental expenditures are expensed or capitalized in accordance with
generally accepted accounting principles. Liabilities for these expenditures are
recorded when it is probable that obligations have been incurred and the amounts
can be reasonably estimated. Reference is made to Note 8 for a discussion of
amounts recorded for these liabilities.
 
  Intangible Assets --
 
     Substantially all intangible assets, included in other assets in the
accompanying consolidated balance sheet, relate to goodwill recognized in
business combinations accounted for as purchases. Goodwill included in other
assets in the accompanying consolidated balance sheet was $88.2 million at
December 31, 1994 and $86.2 million at December 31, 1993, net of accumulated
amortization of $19.9 million and $17.2 million, respectively. Goodwill is being
amortized on a straight-line basis over periods ranging from 20 to 40 years.
Amortization expense recorded during 1994 and 1993 was $7.1 million and $8.1
million, respectively.
 
  Cash Flow Information --
 
     For purposes of the consolidated statement of cash flows, all highly liquid
investments purchased with a maturity of three months or less are considered to
be cash equivalents. The effect of changes in foreign exchange rates on cash
balances has been immaterial. Cash used in operating activities includes cash
payments for interest (net of amounts capitalized) of $469.3 million, $183.6
million and $228.9 million in 1994, 1993 and 1992, respectively. Interest
capitalized for 1994, 1993 and 1992 was $9.0 million, $11.4 million and $8.7
million, respectively. Income taxes paid, net of refunds, during 1994, 1993 and
1992 were $395.1 million, $5.5 million and $2.2 million, respectively. Cash
payments for interest and income taxes in 1994 include $294.3 million and $261.7
million, respectively, paid to the Internal Revenue Service ("IRS") resulting
from the settlement of a dispute relating to a proposed tax deficiency based on
an audit of Pennzoil's 1988 federal income tax return. Reference is made to Note
8 for additional information.

  Earnings Per Share --
 
     Earnings per share are computed based on the weighted average shares of
common stock outstanding. The average shares used in earnings per share
computations for the years 1994, 1993 and 1992 were 46,013,506, 42,187,739 and
40,582,451, respectively.
 
  Foreign Operations --
 
     Consolidated income (loss) from continuing operations before income tax
includes losses from foreign operations of $53.4 million, $17.3 million and
$21.7 million in 1994, 1993 and 1992, respectively.
 
(2) INCOME TAXES --
 
  Accounting for Income Taxes --
 
     In December 1992, Pennzoil announced its decision to change its method of
accounting for income taxes by adopting the requirements of SFAS No. 109,
"Accounting for Income Taxes," effective as of January 1, 1992. Previous 1992
interim period results were restated as a result of the adoption. Prior year
financial statements were not restated to reflect the new accounting method. As
a result of adopting SFAS No. 109, Pennzoil recognized a cumulative, one-time
benefit from the change in accounting principle for periods prior to 1992 of
$115.7 million, or $2.85 per share, as of the first quarter of 1992. In addition
to the cumulative effect, income from continuing operations for the year ended
December 31, 1992, increased $3.4 million ($4.5 million before tax), or $.08 per
share, associated with adopting the new standard.
 
     SFAS No. 109 requires recognition of deferred tax liabilities and assets
for the expected future tax consequences of events that have been included in
the financial statements or tax returns. Under this method, deferred tax
liabilities and assets are determined based on the difference between the
financial statement and tax bases of assets and liabilities using enacted tax
rates in effect for the year in which the differences are expected to reverse.

     Reference is made to Note 8 for information regarding a settlement
agreement entered into with the IRS in October 1994 relating to a proposed tax
deficiency based on an audit of Pennzoil's 1988 federal income tax return.
 
     As a result of the IRS settlement, Pennzoil reduced its tax basis in the
shares of Chevron common stock beneficially owned by Pennzoil. In January 1995,
Pennzoil filed an amended 1993 federal income tax return to reflect the increase
in taxable income for the 1993 sale of shares of Chevron common stock, which was
substantially offset by the utilization of a net operating loss carryforward.
Reference is made to Note 1 for additional information. Realization of the net
operating loss carryforward resulted in the reversal of a valuation allowance of
approximately $44 million. The valuation allowance had previously been reduced
in 1993 by $25.5 million to reflect the net operating loss utilization resulting
from the 1993 sale of shares of Chevron common stock on a pre-settlement basis.
 
     In August 1993, the Omnibus Budget Reconciliation Act of 1993 was enacted,
establishing a new 35% corporate income tax rate effective January 1, 1993. As a
result of the increase in the marginal income tax rate and other tax law
changes, Pennzoil recorded a one-time, non-cash charge of $16.0 million, or $.38
per share, in 1993 to adjust its deferred income tax liabilities and assets for
the effect of the change in income tax rates.
 
     As of December 31, 1994, Pennzoil had a United States net operating loss
carryforward of approximately $8 million, which is available to reduce future
regular federal income taxes payable. Additionally, for purposes of determining
alternative minimum tax, an approximately $7 million net operating loss is
available to offset future alternative minimum taxable income. Utilization of
these regular and alternative minimum tax net operating losses, to the extent
generated in separate return years, is limited based on the separate taxable
income of the subsidiary, or its successor, generating the loss. If not used,
these carryovers will expire in the years 2000 to 2006. In addition, Pennzoil
has approximately $72 million of alternative minimum tax credits indefinitely
available to reduce future regular tax liability to the extent it exceeds the
related alternative minimum tax otherwise due. All net operating loss and credit
carryover amounts are subject to examination by the tax authorities.
 
     Pennzoil also has state net operating loss carryforwards, the tax effect of
which was approximately $19 million as of December 31, 1994. A valuation
allowance of approximately $13 million has been established to offset the
portion of the deferred tax asset related to loss carryforwards expected to
expire before their utilization.

     In August 1994, Pennzoil entered into an amended and restated revolving
credit facility with a group of banks that provides for up to $600 million of
unsecured revolving credit borrowings through August 16, 1995, with any
outstanding borrowings on such date being converted into a term credit facility
terminating on September 1, 1996. Pennzoil has the option, subject to the
extension of additional credit by new or existing banks, of increasing the size
of the facility by $100 million. This amended and restated credit facility
replaces and supersedes the previous revolving credit facilities of Pennzoil.
Borrowings under the facility totaled $205.0 million at December 31, 1994. The
average interest rate applicable to amounts outstanding under this facility and
the previous revolving credit facilities of Pennzoil was 4.69% and 3.59% during
1994 and 1993, respectively.
 
     In June 1994, in connection with its acquisition of Co-enerco Resources,
Ltd. ("Co-enerco"), Pennzoil Canada, Inc. ("Pennzoil Canada"), an indirect
wholly owned subsidiary of Pennzoil, established a Cdn. $260 million credit
facility with a syndicate of Canadian banks, the borrowings of which are
guaranteed by Pennzoil. Also in June 1994, Pennzoil Canada established an
additional Cdn. $40 million credit facility with a Canadian bank, the borrowings
of which are guaranteed by Pennzoil. These facilities provide for borrowings
through May 30, 1995, with any outstanding borrowings on such date being
converted into term credit facilities terminating on May 30, 1996. Borrowings
under these facilities can be made in any combination of U.S. or Canadian
dollars and totaled U.S. $185.0 million and U.S. $10.0 million, respectively, as
of December 31, 1994. The average interest rate applicable to amounts
outstanding under this facility was 5.27% during 1994.
 
     In February 1995, Pennzoil's Board of Directors increased the limit on the
aggregate amount of commercial paper that Pennzoil may issue under its domestic
commercial paper program and/or its Euro-commercial paper program from $250.0
million to $500.0 million. Borrowings under Pennzoil's commercial

paper facilities totaled $243.9 million and $249.4 million at December 31, 1994
and 1993, respectively, and are included in notes payable in the accompanying
consolidated balance sheet. The average interest rates applicable to outstanding
commercial paper were 4.43% and 3.26% during 1994 and 1993, respectively.
 
     Pennzoil has several short-term variable-rate credit arrangements with
certain banks. Pennzoil's Board of Directors has limited borrowings under these
credit arrangements to $200.0 million. Outstanding borrowings totaled $93.3
million and $183.6 million at December 31, 1994 and 1993, respectively, and are
included in notes payable in the accompanying consolidated balance sheet. The
average interest rates applicable to amounts outstanding under these
arrangements were 4.31% and 3.35% during 1994 and 1993, respectively. None of
the banks under these credit arrangements has any obligation to continue to
extend credit after the maturities of outstanding borrowings or to extend the
maturities of any borrowings.
 
     The 6 1/2% Debentures and the 4 3/4% Debentures are exchangeable at the
option of the holders thereof at any time prior to maturity, unless previously
redeemed, for shares of Chevron common stock beneficially owned by Pennzoil at
exchange rates of 23.774 shares and 17.004 shares, respectively, per $1,000
principal amount of the 6 1/2% Debentures and the 4 3/4% Debentures (the
equivalent of $42 1/16 per share and $58 13/16 per share, respectively), subject
to adjustment in certain events. In lieu of delivering certificates representing
shares of Chevron common stock in exchange for the 6 1/2% Debentures and the
4 3/4% Debentures, Pennzoil may, at its option, pay to any holder surrendering
the 6 1/2% Debentures and the 4 3/4% Debentures an amount in cash equal to the
market price of the shares for which the 6 1/2% Debentures and the 4 3/4%
Debentures are exchangeable. Pennzoil has deposited all 18,071,036 shares of
Chevron common stock beneficially owned by Pennzoil with exchange agents for
possible exchange for the 6 1/2% Debentures and the 4 3/4% Debentures.
 
     Under the instruments governing the 6 1/2% Debentures and the 4 3/4%
Debentures, Pennzoil may not pledge, mortgage, hypothecate or grant a security
interest in, or permit any mortgage, pledge, security interest or other lien
upon, the shares of Chevron common stock deposited with exchange agents and
deliverable in exchange for the 6 1/2% Debentures and the 4 3/4% Debentures.
Pennzoil may at any time obtain from the exchange agents or otherwise authorize
or direct the exchange agents to release all or part of the 18,071,036 shares of
Chevron common stock deposited with the exchange agents. However, in the event
Pennzoil obtains or otherwise releases any shares of Chevron common stock
subject to exchange, each holder of a 6 1/2% Debenture or a 4 3/4% Debenture
will generally have the right, at such holder's option, to require Pennzoil to
repurchase all or a portion of such holder's debentures at a premium.
 
     In 1993 and 1992, Pennzoil redeemed amounts outstanding under several debt
facilities using proceeds from various sources. The premiums and related
unamortized discount and debt issue costs relating to these redemptions resulted
in extraordinary charges of $18.4 million ($28.3 million before tax), or $.44
per share, in 1993 and $16.6 million ($25.2 million before tax), or $.41 share,
in 1992.
 
     At December 31, 1994, maturities of long-term debt for the years ending
December 31, 1995 to 1999 were $1.8 million, $405.8 million, $6.7 million, $2.5
million and $200.4 million, respectively. These maturities include $400 million
in 1996 related to the maturities of Pennzoil's revolving credit facilities.
Such maturities also include $3.9 million and $5.2 million for the years ending
December 31, 1996 and 1997, respectively, related to non-interest bearing
promissory notes of Jiffy Lube International, Inc. ("Jiffy Lube"), a wholly
owned subsidiary of Pennzoil, the payment of which is contingent upon the future
profitability of Jiffy Lube.
 
(4) FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK AND CONCENTRATIONS OF
    CREDIT RISK --
 
  Financial Instruments with Off-Balance-Sheet Risk --
 
     Pennzoil is a party to various financial instruments with off-balance-sheet
risk as part of its normal course of business, including financial guarantees
and contractual commitments to extend financial guarantees, credit and other
assistance to customers, franchisees and other third parties. These financial
instruments involve, to varying degrees, elements of credit risk which are not
recognized in Pennzoil's consolidated balance sheet.

                       PENNZOIL COMPANY AND SUBSIDIARIES
 
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
     The financial guarantees primarily relate to debt and lease obligation
guarantees with expiration dates of up to twenty years issued to third parties
to guarantee the performance of customers and franchisees in the fast lube
industry. Commitments to extend credit are also provided to fast lube industry
participants to finance equipment purchases, working capital needs and, in some
cases, the acquisition of land and construction of improvements. Contractual
commitments to extend credit and other assistance are in effect as long as
certain conditions established in the respective contracts are met. Contractual
commitments to extend financial guarantees are conditioned on the occurrence of
specified events. The largest of these commitments is to provide a guarantee for
letters of credit issued by third parties to meet the reinsurance requirements
of Pennzoil's captive insurance subsidiary. This commitment has no stated
maturity and is expected to vary in amount from year to year to meet the
reinsurance requirements. Reserves established for reported and incurred but not
reported insurance losses in the amount of $35.4 million and $32.3 million have
been recognized in Pennzoil's consolidated balance sheet as of December 31, 1994
and 1993, respectively. The credit risk to Pennzoil is mitigated by the
insurance subsidiary's portfolio of high-quality, short-term investments used to
collateralize the letters of credit. At December 31, 1994, the collateral was
valued at approximately 141% of the credit risk.
 
     In addition, in connection with Pennzoil's disposition of Purolator
Products Company ("Purolator") in 1992, Pennzoil entered into an agreement with
certain banks to provide contingent credit support for a Purolator credit
facility. This obligation was terminated in November 1994 upon the payment in
full of all obligations due under the facility by Purolator and the termination
of the facility.
 
     Also, in connection with Pennzoil's disposition of Purolator in 1992,
Pennzoil entered into an agreement with the Pension Benefit Guaranty Corporation
("PBGC"), pursuant to which Pennzoil agreed that, for up to five years, in the
event of the termination of any or all the employee benefit plans of Purolator
that are subject to Title IV of the Employee Retirement Income Security Act of
1974, as amended ("ERISA"), and the inability of the PBGC in good faith to
collect the amounts of any unfunded benefit liabilities under Purolator's plans
from Purolator or any person controlling Purolator, Pennzoil would guarantee up
to $7.0 million of such unfunded benefit liabilities.
 
     Following are the amounts related to Pennzoil's financial guarantees and
contractual commitments to extend financial guarantees, credit and other
assistance as of December 31, 1994 and 1993.

     Pennzoil's exposure to credit losses in the event of nonperformance by the
other parties to these financial instruments is represented by the contractual
or notional amounts. Decisions to extend financial guarantees and commitments
and the amount of remuneration and collateral required are based on management's
credit evaluation of the counterparties on a case-by-case basis. The collateral
held varies but may include accounts receivable, inventory, equipment, real
property, securities and personal assets. Since many of the commit-

ments are expected to expire without being drawn upon, the total commitment
amounts do not necessarily represent future cash requirements.
 
  Concentrations of Credit Risk --
 
     Pennzoil extends credit to various companies in the oil and gas, motor oil
and refined products, fast lube and sulphur industries in the normal course of
business. Within these industries, certain concentrations of credit risk exist.
These concentrations of credit risk may be similarly affected by changes in
economic or other conditions and may, accordingly, impact Pennzoil's overall
credit risk. However, management believes that consolidated receivables are well
diversified, thereby reducing potential credit risk to Pennzoil, and that
allowances for doubtful accounts are adequate to absorb estimated losses as of
December 31, 1994. Pennzoil's policies concerning collateral requirements and
the types of collateral obtained for on-balance-sheet financial instruments are
the same as those described above under "Financial Instruments with
Off-Balance-Sheet Risk."
 
     At December 31, 1994, receivables related to these group concentrations in
the oil and gas, motor oil and refined products, fast lube and sulphur
industries were $128.1 million, $223.3 million, $31.8 million and $13.4 million,
respectively, compared with $182.8 million, $181.4 million, $36.9 million and
$8.9 million, respectively, at December 31, 1993.
 
(5) FAIR VALUE OF FINANCIAL INSTRUMENTS --
 
     The carrying amounts of Pennzoil's short-term financial instruments,
including cash equivalents, current marketable securities and other investments,
trade accounts receivable, trade accounts payable and notes payable, approximate
their fair values based on the short maturities of those instruments and on
quoted market prices, where such prices are available.
 
     The following table summarizes the carrying amounts and estimated fair
values of Pennzoil's other financial instruments.

     The following methods and assumptions were used to estimate the fair value
of each class of financial instrument included above:
 
  Notes Receivable --
 
     The estimated fair value of notes receivable is based on discounting future
cash flows using estimated year-end interest rates at which similar loans have
been made to borrowers with similar credit ratings for the same remaining
maturities.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
  Long-Term Investments --
 
     The estimated fair value of long-term investments is based on quoted market
prices at year end for those investments, adjusted for any reserves for
debenture exchange rights, where applicable. Reference is made to Note 1 for
additional information.
 
  Long-Term Debt --
 
     The estimated fair value of Pennzoil's long-term debt is based on quoted
market prices or, where such prices are not available, on estimated year-end
interest rates of debt with the same remaining average maturities and credit
quality.
 
  Off-Balance-Sheet Financial Instruments --
 
     The estimated fair value of certain financial guarantees written and
commitments to extend financial guarantees is based on the estimated cost to
Pennzoil to obtain third party letters of credit to relieve Pennzoil of its
obligations under such guarantees or, in the case of certain lease guarantees
related to Jiffy Lube franchisees, the present value of expected future cash
flows using a discount rate commensurate with the risks involved. Reference is
made to Note 4 for further information regarding off-balance-sheet financial
instruments.
 
(6) BENEFIT PLANS --
 
  Retirement Plans --
 
     Substantially all employees are covered by non-contributory retirement
plans which provide benefits based on the participants' years of service and
compensation or stated amounts for each year of service. Annual contributions to
the plans are made in accordance with the minimum funding provisions of ERISA
where applicable, but not in excess of the maximum amount that can be deducted
for federal income tax purposes.

  Postretirement Health Care and Life Insurance Benefits --
 
     Pennzoil sponsors several unfunded defined benefit postretirement plans
covering most salaried and hourly employees. The plans provide medical and life
insurance benefits and are, depending on the type of plan, either contributory
or non-contributory. The accounting for the health care plans anticipates future
cost-sharing changes that are consistent with Pennzoil's expressed intent to
increase, where possible, contributions from future retirees to a minimum of 30%
of the total annual cost. Furthermore, Pennzoil's future contributions for both
current and future retirees have been limited, where possible, to 200% of the
average 1992 benefit cost.

</TABLE>
 
     For measurement purposes, a 10% annual rate of increase in the per capita
cost of covered health care benefits was assumed for 1995; the rate was assumed
to decrease gradually to 6% through the year 2002 and remain at that level
thereafter. The health care cost trend rate assumption has a significant effect
on the amount of the obligation and periodic cost reported. An increase in the
assumed health care cost trend rates by 1% in each year would increase the
accumulated postretirement benefit obligation as of December 31, 1994 by $2.7
million and the aggregate of the service and interest cost components of net
periodic postretirement benefit cost for the year then ended by $.3 million.
 
     The weighted-average discount rates used in determining the accumulated
postretirement benefit obligation as of December 31, 1994 and 1993 were 8.5% and
7.5%, respectively.
 
  Contribution Plans --
 
     Pennzoil has defined contribution plans covering substantially all
employees who have completed one year of service. Employee contributions of not
less than 1% to not more than 6% of each covered employee's compensation are
matched between 50% and 100% by Pennzoil. The cost of such company contributions
totaled $10.0 million in 1994, $9.4 million in 1993 and $9.1 million in 1992.
 
  Postemployment Benefits --
 
     Effective January 1, 1994, Pennzoil changed its method of accounting for
postemployment benefit costs by adopting the new requirements of SFAS No. 112,
"Employers' Accounting for Postemployment Benefits." This standard requires
employers to recognize the obligation to provide postemployment benefits if the
obligation is attributable to employees' services already rendered, employees'
rights to those benefits accumulate or vest, payment of the benefits is probable
and the amounts can be reasonably estimated. If those four conditions are not
met, the employer should recognize the obligation to provide postemployment
benefits

when it is probable that a liability has been incurred and the amount can be
reasonably estimated. Pennzoil recorded a charge of $4.9 million ($7.6 million
before tax), or $.11 per share, as of January 1, 1994 to reflect the cumulative
effect of the change in accounting principle for periods prior to 1994.
 
(7) CAPITAL STOCK AND STOCK OPTIONS --
 
     Pennzoil's Restated Certificate of Incorporation authorizes the issuance of
up to 9,747,720 shares of preferred stock. None of these shares were issued or
outstanding at December 31, 1994. Pursuant to its authority to divide the
preferred stock into a series, the Board of Directors in October 1994 designated
750,000 shares of preferred stock as a series of "Series A Junior Participating
Preferred Stock." The Series A Junior Participating Preferred Stock is issuable
upon the exercise of certain rights to purchase the Series A Junior
Participating Preferred Stock ("Rights"). One Right was distributed with respect
to each share of Pennzoil common stock outstanding at the close of business on
November 11, 1994, and Rights are issuable with all subsequently issued shares
of Pennzoil common stock prior to the date the Rights become exercisable or
expire. The Rights are not currently exercisable or transferable apart from the
Pennzoil common stock. Each Right entitles the holder to purchase from Pennzoil
a unit consisting of one one-hundredth of a share of Series A Junior
Participating Preferred Stock at $140 per share upon the occurrence of certain
specified events.
 
     Pennzoil's Restated Certificate of Incorporation authorizes the issuance of
up to 27,862,924 shares of preference common stock. None of these shares were
issued or outstanding at December 31, 1994. Dividend rights on any preference
common stock are junior to the rights of any Pennzoil preferred stock and senior
to the rights of Pennzoil common stock.
 
     In September 1993, Pennzoil completed the sale, pursuant to underwritten
public offerings, of 5,000,000 shares of its common stock at a price of $62.50
per share. The net proceeds from the sale of the shares of Pennzoil common stock
offered, prior to the payment of expenses, totaled approximately $303.3 million.
Primarily utilizing funds from such offerings, Pennzoil redeemed an aggregate of
$292.5 million principal amount of Pennzoil's debentures. Reference is made to
Note 3 for additional information. Pro forma earnings per share for the year
ended December 31, 1993, assuming the stock offering and redemption of
debentures had occurred at the beginning of 1993, were $3.43 per share.
 
     At December 31, 1994, Pennzoil had 2,774,187 shares of common stock
reserved for issuance upon the grant and exercise of stock options and the grant
and maturity of conditional stock awards. An additional 850,000 shares of
Pennzoil common stock were reserved for issuance upon the grant and exercise of
stock options in February 1995.
 
     At December 31, 1994, Pennzoil had nonqualified and incentive stock option
plans covering a total of 2,601,982 shares of Pennzoil common stock (compared to
2,620,565 shares at December 31, 1993), of which 621,633 shares were available
for granting of options. Options granted under the plans have a maximum term of
ten years and are exercisable under the terms of the respective option
agreements at the market price of the common stock at the date of grant, subject
to antidilution adjustments in certain circumstances. At December 31, 1994,
expiration dates for the outstanding options ranged from December 1997 to August
2004 and the average exercise price per share was $63.75. Payment of the
exercise price may be made in cash or in shares of Pennzoil common stock
previously owned by the optionee, valued at the then-current market value.

     In 1994, there were 20,620 units of common stock granted to selected
employees under Pennzoil's conditional stock award programs. Awards under the
programs are made in the form of units which entitle the recipient to receive,
at the end of a specified period, subject to certain conditions of continued
employment, a number of shares of Pennzoil common stock equal to the number of
units granted. At December 31, 1994, units covering 79,778 shares of Pennzoil
common stock were outstanding (compared to 73,853 shares at December 31, 1993).
In 1994, 14,695 shares of Pennzoil common stock were distributed to selected
employees upon maturity of awards granted under Pennzoil's conditional stock
award programs.
 
(8) COMMITMENTS AND CONTINGENCIES --
 
  Tax Dispute --
 
     In 1988, Pennzoil received $3.0 billion from Texaco Inc. ("Texaco") in
settlement of all litigation between Pennzoil and Texaco arising out of Texaco's
tortious interference with Pennzoil's contractual rights to purchase a minority
interest in Getty Oil Company. From 1989 through 1991, Pennzoil acquired
32,944,100 shares of Chevron common stock with approximately $2.2 billion of the
net Texaco settlement proceeds. For financial reporting purposes, Pennzoil
reported an extraordinary gain of $1.656 billion (after expenses and estimated
current and deferred taxes), or $42.62 per share, associated with the $3.0
billion in cash received from Texaco in April 1988. For federal income tax
purposes, Pennzoil originally reported that it recognized no gain upon receipt
of the $3.0 billion and that $366 million in legal and other costs incurred in
the Texaco litigation was fully deductible. Pennzoil's reporting position was
based on its belief that, under Section 1033 of the Internal Revenue Code, the
$3.0 billion received from Texaco was an amount realized as a result of the
involuntary conversion of property and that the Chevron shares were similar or
related in service or use to the property converted by Texaco. A corollary of
this position is that Pennzoil would have no tax basis in the Chevron shares.
During 1990 and 1991, Pennzoil recalculated its 1988 federal income tax
liability to recognize approximately $800 million of income, representing the
excess of the $3.0 billion received from Texaco over the amount expended to
acquire Chevron shares. As a result of these adjustments, current taxes were
increased, and deferred taxes were decreased, by $120.4 million in 1990 and
$13.2 million in 1991. In addition, Pennzoil paid interest on such taxes of
$17.6 million during 1990 and $3.7 million in 1991.
 
     In January 1994, Pennzoil received a letter and examination report from the
District Director of the IRS that proposed a tax deficiency based on an audit of
Pennzoil's 1988 federal income tax return. The examination report proposed two
principal adjustments with which Pennzoil disagreed.
 
     The first adjustment challenged Pennzoil's position under Section 1033 of
the Internal Revenue Code that (i) at least $2.2 billion of the $3.0 billion
cash payment received from Texaco in 1988 in settlement of litigation was
realized as a result of the involuntary conversion of property and (ii) the
shares of Chevron common stock purchased with $2.2 billion of the net Texaco
settlement proceeds were similar or related in service or use to the property
converted by Texaco. The proposed tax deficiency relating to this proposed

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
adjustment was $550.9 million, net of available offsets. Pennzoil estimated that
the additional after-tax interest on this proposed deficiency was approximately
$234.3 million as of December 31, 1993.
 
     The second adjustment proposed by the IRS would have permanently
capitalized, rather than allow Pennzoil to deduct, approximately $366 million
incurred by Pennzoil in 1988 and earlier years for litigation and related
expenses in connection with the Texaco settlement, even if it were determined
that the entire $3.0 billion was includable in Pennzoil's 1988 taxable income.
The proposed tax deficiency relating to the disallowance of deductions was
$124.6 million, and the estimated additional after-tax interest on this proposed
deficiency was approximately $46.7 million as of December 31, 1993.
 
     In October 1994, Pennzoil entered into a settlement agreement with the IRS
to treat $618 million of the $2.2 billion as proceeds from an involuntary
conversion; to reduce such amount by $72 million of litigation costs; to
recognize the balance of the settlement proceeds as taxable income in 1988; and
to allow the balance of the litigation costs as deductions in 1988. As a result,
Pennzoil sustained a tax deficiency for 1988 of $261.7 million (net of available
offsets), plus interest, and its tax basis in each Chevron share was its cost
less $8.28 (after giving effect to a "two-for-one" stock split of Chevron common
stock which occurred in June 1994). Total interest charges on the tax deficiency
were $294.3 million, resulting in a total cash payment to the IRS of $556.0
million in October 1994.
 
     In October 1992, Pennzoil completed a tax-free transaction with Chevron,
pursuant to which Pennzoil exchanged 15,750,000 shares of Chevron common stock
beneficially owned by Pennzoil for all the capital stock of Pennzoil Petroleum
Company ("Pennzoil Petroleum"), which owned Gulf of Mexico, Gulf Coast, Permian
Basin and other domestic oil and gas producing properties. Reference is made to
Note 10 for additional information. Under the liability method of accounting for
income taxes adopted by Pennzoil in December 1992, the excess of the amount of
Pennzoil's investment in Pennzoil Petroleum capital stock for financial
reporting purposes over the tax basis of such investment was not expected to
result in future income tax liability. Accordingly, deferred income taxes
attributable to the Chevron common stock exchanged in 1992, which taxes were
originally provided when the Texaco settlement proceeds were received in 1988,
were reflected as a reduction of the cost of Pennzoil's investment in Pennzoil
Petroleum. As a result of the IRS settlement, Pennzoil increased the balance of
its investment in Pennzoil Petroleum capital stock for financial reporting
purposes and, therefore, the carrying value of Pennzoil Petroleum's oil and gas
properties by $390.3 million, and such increased investment resulted in a $93.9
million increase in depreciation, depletion and amortization expense recognized
in October 1994 relating to Pennzoil Petroleum's oil and gas properties from the
date of the acquisition of Pennzoil Petroleum to the date of the IRS settlement.
These adjustments resulted in a net increase in property, plant and equipment of
$296.4 million as of September 30, 1994, while interest charges and
depreciation, depletion and amortization expense adjustments related to the IRS
settlement reduced Pennzoil's 1994 pretax income by $388.2 million. After
consideration of available tax offsets, the IRS settlement resulted in a 1994
after-tax charge of $210.4 million, or $4.57 per share.
 
  Curtailment Litigation --
 
     United Gas Pipe Line Company ("United"), a former subsidiary of Pennzoil,
curtailed deliveries of natural gas to its customers in accordance with
priorities contained in its tariffs during the 1970s and early 1980s. Several
lawsuits filed by industrial and power plant "direct sale" customers for damages
allegedly caused by curtailments were brought against United, and Pennzoil was
joined as a defendant in five of these suits. The only remaining suit against
United involving Pennzoil is an action filed in the United States District Court
for the Southern District of Mississippi on November 14, 1974 by Mississippi
Power Co. ("MPCo"), which alleges damages of approximately $44.7 million and
seeks to have such damages trebled pursuant to federal antitrust laws. In
related proceedings before the Federal Energy Regulatory Commission ("FERC"),
MPCo has introduced evidence indicating that its claimed damages (before
trebling) have increased to approximately $88.2 million. In 1977, the judge in
the MPCo case referred certain issues to the FERC and

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
stayed all proceedings pending action by the FERC. No action has been taken
since 1977 to remove the stay. Pennzoil believes that it has no liability for
any action it has taken or omitted to take, that it can successfully defend
itself in the action and that the final outcome of the case will not have a
material adverse effect on its financial condition or results of operations.
 
  Environmental Matters --
 
     Pennzoil is subject to certain laws and regulations relating to
environmental remediation activities associated with past operations, such as
the Comprehensive Environmental Response, Compensation, and Liability Act
("CERCLA"), the Resource Conservation and Recovery Act and similar state
statutes. In response to liabilities associated with these activities, accruals
have been established when reasonable estimates are possible. Such accruals
primarily include estimated costs associated with remediation. Pennzoil has not
used discounting in determining its accrued liabilities for environmental
remediation, and no claims for possible recovery from third party insurers or
other parties related to environmental costs have been recognized in Pennzoil's
consolidated financial statements. Pennzoil adjusts the accruals when new
remediation responsibilities are discovered and probable costs become estimable,
or when current remediation estimates must be adjusted to reflect new
information.
 
     In connection with Pennzoil's disposition of Purolator, Pennzoil and
Purolator entered into an indemnification agreement pursuant to which Pennzoil
agreed to reimburse Purolator for the costs and expenses of certain
environmental remediation activities at a plant operated by Purolator in Elmira
Heights, New York, and certain environmental remediation activities, if any,
required at one other site located near the Elmira facility and a landfill site
located in Metamora, Michigan. Pennzoil had a reserve of $16.2 million and $16.3
million recorded with respect to its obligations under its indemnification
agreement with Purolator as of December 31, 1994 and 1993, respectively.
Reference is made to Note 11 for additional information.
 
     Certain of Pennzoil's subsidiaries are involved in matters in which it has
been alleged that such subsidiaries are potentially responsible parties ("PRPs")
under CERCLA or similar state legislation with respect to various waste disposal
areas owned or operated by third parties. In addition, certain of Pennzoil's
subsidiaries are involved in other environmental remediation activities,
including the removal, inspection and replacement, as necessary, of underground
storage tanks. As of December 31, 1994 and 1993, Pennzoil's consolidated balance
sheet included accrued liabilities for environmental remediation of $44.9
million and $33.1 million, respectively, which amounts include reserves with
respect to Pennzoil's obligations under its indemnification agreement with
Purolator referred to in the previous paragraph. Of these reserves, $8.8 million
and $4.8 million are reflected on the consolidated balance sheet as current
liabilities as of December 31, 1994 and 1993, respectively, and $36.1 million
and $28.3 million are reflected as other liabilities as of December 31, 1994 and
1993, respectively. Pennzoil does not currently believe there is a reasonable
possibility of incurring additional material amounts in excess of the current
accruals recognized for such environmental remediation activities. With respect
to the sites in which Pennzoil subsidiaries are PRPs, Pennzoil's conclusion is
based in large part on (i) the availability of defenses to liability, including
the availability of the "petroleum exclusion" under CERCLA and similar state
laws, and/or (ii) Pennzoil's current belief that its share of wastes at a
particular site is or will be viewed by the Environmental Protection Agency or
other PRPs as being de minimis. As a result, Pennzoil's monetary exposure is not
expected to be material.
 
  Franchisee Litigation --
 
     Certain current and former franchisees of Jiffy Lube have brought suit
against Jiffy Lube to challenge various matters relating to the
franchisor-franchisee relationship. Certain of the suits have included
allegations against Pennzoil and/or Pennzoil Products Company, a wholly owned
subsidiary of Pennzoil, as well. Pennzoil does not believe that the final
outcome of these cases will have a material adverse effect on its financial
condition or results of operations.

(9) LEASES --
 
  As Lessee --
 
     Pennzoil leases various assets and office space with lease periods of 1 to
20 years. Additionally, Jiffy Lube leases sites and equipment which are
subleased to franchisees or used in the operation of automotive fast lubrication
and fluid maintenance service centers operated by Jiffy Lube. The typical lease
period for the service centers is 20 years with escalation clauses generally
increasing the lease payments by 9% every third year, with some leases
containing renewal options generally for periods of five years. These leases,
excluding leases for land that are classified as operating leases, are accounted
for as capital leases and are capitalized using interest rates appropriate at
the inception of each lease.
 
     Certain operating and capital lease payments are contingent upon such
factors as the consumer price index or the prime interest rate with any future
changes reflected in income as accruable. The effects of these changes are not
considered material.
 
     Total operating lease rental expenses for Pennzoil (exclusive of oil and
gas lease rentals) were $63.5 million, $59.6 million and $56.2 million for 1994,
1993 and 1992, respectively. Non-current capital lease obligations are
classified as other liabilities in the accompanying consolidated balance sheet.
 
     Future minimum commitments under noncancellable leasing arrangements as of
December 31, 1994 are as follows:

  As Lessor --
 
     Pennzoil, through Jiffy Lube, owns or leases numerous service center sites
which are leased or subleased to franchisees. Buildings owned or leased that
meet the criteria for direct financing leases are carried at the gross
investment in the lease less unearned income. Unearned income is recognized in
such a manner as to produce a constant periodic rate of return on the net
investment in the direct financing lease. Any buildings leased or subleased that
do not meet the criteria for a direct financing lease and any land leased or
subleased are accounted for as operating leases. The typical lease period is 20
years and some leases contain renewal options. The franchisee is responsible for
the payment of property taxes, insurance and maintenance costs related to the
leased property. The net investment in direct financing leases is classified as
other assets in the accompanying consolidated balance sheet.

(10) ACQUISITIONS AND DIVESTITURES --
 
  Acquisition of Pennzoil Petroleum --
 
     In October 1992, Pennzoil completed a tax-free transaction with Chevron,
pursuant to which Pennzoil exchanged 15,750,000 shares of Chevron common stock
beneficially owned by Pennzoil for all the capital stock of Pennzoil Petroleum,
which owned Gulf of Mexico, Gulf Coast, Permian Basin and other domestic oil and
gas producing properties. The exchange of stock was accounted for using the
purchase method of accounting, and the results of operations of Pennzoil
Petroleum subsequent to October 30, 1992 have been included in Pennzoil's oil
and gas segment results. The fair market value of the 15,750,000 shares of
Chevron common stock exchanged for the capital stock of Pennzoil Petroleum
approximated Pennzoil's historical book value for such shares of $1.06 billion.
Accordingly, Pennzoil used the net book value of the Chevron shares exchanged
for purposes of purchase accounting.
 
     Included in the assets of Pennzoil Petroleum at the time of the transfer to
Pennzoil was $57.4 million in cash contributed by Chevron to Pennzoil Petroleum
immediately prior to closing, representing the net cash flow from Pennzoil
Petroleum's operations during the four-month period between the "effective date"
and the closing date of the transaction, after reduction as a result of
nonrecurring closing adjustments of approximately $11 million. As a result of an
audit completed during 1993, Chevron contributed an additional $9.9 million in
cash to Pennzoil Petroleum in 1993, representing an adjustment to the initial
$57.4 million cash contribution made by Chevron to Pennzoil Petroleum prior to
closing. This additional contribution from Chevron was accounted for as an
adjustment to the original purchase price of Pennzoil Petroleum. As a result of
an audit conducted during 1994, Chevron contributed an additional $6.8 million
in cash to Pennzoil Petroleum in 1994, representing post-closing adjustments
related to the acquisition.

     The following unaudited pro forma information has been prepared assuming
that the acquisition of Pennzoil Petroleum had occurred at the beginning of the
period presented. Permitted pro forma adjustments include only the effects of
events directly attributable to a transaction that are factually supportable and
expected to have a continuing impact. Pro forma adjustments reflecting
anticipated "efficiencies" in operations resulting from a transaction are, under
most circumstances, not permitted. As a result of the limitations imposed with
regard to the types of permitted pro forma adjustments, Pennzoil believes that
this unaudited pro forma information is not indicative of future results of
operations, nor the results of historical operations had the acquisition of
Pennzoil Petroleum been consummated as of the assumed dates.

  Acquisition of Co-enerco Resources Ltd. --
 
     In June 1994, Pennzoil Canada acquired Co-enerco, a Canadian oil and gas
exploration and production company operating in Alberta, northeastern British
Columbia and southeastern Saskatchewan. Pennzoil Canada paid $230.9 million in
cash in connection with the acquisition of Co-enerco and the repayment of Co-
enerco's outstanding bank debt, which was financed primarily through two credit
facilities. Reference is made to Note 3 for additional information. The
acquisition of Co-enerco was accounted for using the purchase method of
accounting, and the results of operations of Co-enerco subsequent to June 30,
1994 have been included in Pennzoil's oil and gas segment results.
 
  Sale of Domestic Sulphur Assets --
 
     In October 1994, Pennzoil entered into an agreement with Freeport-McMoRan
providing for the sale by Pennzoil to Freeport-McMoRan of substantially all the
domestic assets of Pennzoil's sulphur segment. The transaction was completed in
January 1995. Pennzoil continues to own and operate its Antwerp, Belgium sulphur
terminal and the related international sulphur business. As consideration under
the agreement, Freeport-McMoRan assumed certain liabilities of Pennzoil relating
to or arising out of the business of Pennzoil's sulphur segment, and Pennzoil
will be entitled to receive a series of quarterly installment payments from
Freeport-McMoRan for periods through December 31, 2014, subject to the
prevailing market price of sulphur. The installment payments, recorded at their
estimated fair value of $22.5 million as of September 30, 1994, may be
terminated earlier by Freeport-McMoRan (through the exercise of a call option
providing for a $65 million payment to Pennzoil), or by Pennzoil (through the
exercise of a put option providing for a $10 million payment to Pennzoil).
Neither the call option nor the put option may be exercised prior to January
1999. In connection with this transaction, Pennzoil's sulphur segment recorded a
charge to depreciation, depletion and amortization expense of $50.2 million
($32.6 million after tax, or $.71 per share) in September 1994.

(11) DISCONTINUED OPERATIONS --
 
  Filtration Products Segment --
 
     In October 1992, as a result of Pennzoil's conclusion that disposal of
Purolator's filtration products operations would enhance Pennzoil's efforts to
focus on its strategic businesses and to reduce indebtedness, Purolator filed a
registration statement pursuant to which Pennzoil offered to the public all
shares of Purolator stock held by Pennzoil. Accordingly, Purolator's net assets
and results of operations for all periods have been reclassified as discontinued
operations for financial reporting purposes. In December 1992, Pennzoil sold in
initial public offerings all its shares of capital stock of Purolator. The total
amount received by Pennzoil, prior to the payment of expenses, from the net
proceeds of the offerings and the repayment of indebtedness by Purolator was
$206.0 million. Pennzoil recorded a net gain on the disposition of Purolator
stock of $1.5 million ($20.0 million before tax loss), or $.04 per share, in
1992.
 
     In connection with Pennzoil's disposition of Purolator, Pennzoil and
Purolator entered into an indemnification agreement with respect to certain
environmental matters. Reference is made to Note 8 for additional information.
In addition, Pennzoil entered into an agreement with certain banks to provide
contingent credit support for a Purolator credit facility and an agreement with
a government agency with respect to guarantees of benefits under certain of
Purolator's employee benefit plans. Reference is made to Note 4 for additional
information.

 (1) Costs incurred for unproved property acquisition during 1994 and 1993
     include approximately $48 million and $98 million, respectively, related to
     the gas utilization project in Azerbaijan. Total costs incurred during 1994
     and 1993 include $50 million and $114 million, respectively, related to
     Pennzoil's Azerbaijan activities. Pennzoil's investment in the gas
     utilization project is being recovered through partial credit toward
     Pennzoil's portion of the first bonus payment made by members of the
     consortium of foreign oil companies to the government of Azerbaijan, direct
     hard currency payments by the Azerbaijan government during 1995 and an
     interest in another project. Any remaining balance due from the government
     of Azerbaijan with respect to the gas utilization project will be
     creditable against the remaining bonus payments to be made to the
     Azerbaijan government by the consortium. Total costs incurred for North
     America in 1994, including the acquisition of Co-enerco, were $602 million.
 
 (2) Costs incurred for property acquisitions in 1994 include $231 million
     attributable to the acquisition of Co-enerco. Costs incurred for property
     acquisitions in 1992 include $1,009 million attributable to the acquisition
     of Pennzoil Petroleum. Reference is made to Note 10 of Notes to
     Consolidated Financial Statements for additional information.

     This information is similar to the disclosures set forth in the "Industry
Segment Financial Information" set forth on pages 1 and 2 herein but differs in
several respects as to the level of detail, geographic presentation and income
taxes. Income taxes were determined by applying the applicable statutory rates
to pretax income with adjustment for tax credits and other allowances. Income
tax provisions involved certain allocations among geographic areas based on
management's assessment of the principal factors giving rise to the tax
obligation.

(1) Foreign technical support and other during 1994 and 1993 includes
    approximately $9 million and $7 million, respectively, related to Pennzoil's
    Azerbaijan activities.
 
(2) In October 1994, Pennzoil settled a dispute with the IRS relating to a
    proposed tax deficiency based on an audit of Pennzoil's 1988 federal income
    tax return. As a result of the IRS settlement, Pennzoil increased the
    balance of its investment in Pennzoil Petroleum capital stock for financial
    reporting purposes and, therefore, the carrying value of Pennzoil
    Petroleum's oil and gas properties by $390.3 million, and such increased
    investment resulted in a $93.9 million increase in depreciation, depletion
    and amortization expense recognized in October 1994 relating to Pennzoil
    Petroleum's oil and gas properties from the date of the acquisition of
    Pennzoil Petroleum to the date of the IRS settlement. Reference is made to
    Notes 8 and 10 for additional information.

 Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil
 and Gas Reserves (Standardized Measure)
 
     The Standardized Measure is determined on a basis which presumes that
year-end economic and operating conditions will continue over the periods during
which year-end proved reserves would be produced. Neither the effects of future
inflation nor expected future changes in technology and operating practices have
been considered.
 
     The Standardized Measure is determined as the excess of future cash inflows
from proved reserves less future costs of producing and developing the reserves,
future income taxes and a discount factor. Future cash inflows represent the
revenues that would be received from production of year-end proved reserve
quantities assuming the future production would be sold at year-end prices plus
any fixed and determinable future escalations (but not escalations based on
inflation) of natural gas prices provided by existing contracts. As a result of
the continued volatility in oil and natural gas markets, future prices received
from oil, condensate and natural gas sales may be higher or lower than current
levels.
 
     Future production costs include the estimated expenditures related to
production of the proved reserves plus any production taxes without
consideration of inflation. Future development costs include the estimated costs
of drilling development wells and installation of production facilities, plus
the net costs associated with dismantlement and abandonment of wells and
production platforms, assuming year-end costs continue without inflation. Future
income taxes were determined by applying current legislated statutory rates to
the excess of (a) future cash inflows, less future production and development
costs, over (b) the tax basis in the properties involved plus existing net
operating loss carryforwards. Tax credits are considered in the computation of
future income tax expenses. The discount was determined by applying a discount
rate of 10% per year to the annual future net cash flows.

OIL AND GAS INFORMATION (CONTINUED)
 
     The Standardized Measure does not purport to be an estimate of the fair
market value of Pennzoil's proved reserves. An estimate of fair market value
would also take into account, among other things, the expected recovery of
reserves in excess of proved reserves, anticipated changes in future prices and
costs and a discount factor more representative of the time value of money and
the risks inherent in producing oil and gas. In the opinion of Pennzoil's
management, the estimated fair value of Pennzoil's oil and gas properties is in
excess of the amounts set forth below.

Pennzoil Company
Post Office Box 2967
Houston, Texas  77001

Gentlemen:

                 At your request we have prepared an estimate of the reserves,
future production, and income attributable to certain leasehold and royalty
interests of Pennzoil Company including Pennzoil Exploration and Production
Company, Pennzoil Petroleums, Ltd.  (excluding those properties purchased from
Co-enerco Resources Ltd.), Pennzoil Products Company, and Pennzoil Company
(formerly Proven Properties, Inc.) (collectively referred to herein as the
Company) as of December 31, 1994.  In accordance with the requirements of FASB
69, our estimates of the Company's net proved reserves as of December 31, 1991,
1992, 1993, and 1994, as contained in this report and our previous reports, are
presented in attached Table No. 1 together with a tabulation of the components
of the differences in the estimates as of such dates.  The Company's reserves
in the United States are located in all the main producing states (except
Alaska), and in state and federal waters offshore Alabama, California,
Louisiana, and Texas.  The Company's foreign reserves are located in Canada.

                 The estimated reserve volumes and future income amounts
presented in this report are related to hydrocarbon prices.  December 1994
hydrocarbon prices were used in the preparation of this report as required by
Securities and Exchange Commission (SEC) and Financial Accounting Standards
Bulletin No. 69 (FASB 69) guidelines; however, actual future prices may vary
significantly from December 1994 prices.  Therefore, volumes of reserves
actually recovered and amounts of income actually received may differ
significantly from the estimated quantities presented in this report.  Our
estimates of the proved net reserves attributable to the interests of the
Company as of December 31, 1994 are shown below:

                 The "Liquid" reserves shown above are comprised of crude oil,
condensate, and natural gas liquids.  Natural gas liquids comprise 18 percent
of the Company's developed liquid reserves and 16 percent of the Company's
developed and undeveloped liquid reserves.  All hydrocarbon liquid reserves are
expressed in standard 42 gallon barrels.  All gas volumes are hydrocarbon sales
gas

expressed in MMCF at the pressure and temperature bases of the area where the
gas reserves are located.  Our estimates of hydrocarbon sales gas reserves as
of December 31, 1994 do not include 160,678 MMCF of carbon dioxide which is
also sales gas.  Revenues from carbon dioxide sales are included in our
estimates of future cash inflows as of December 31, 1994.  In addition, the
Company owns 83,819 long tons of sulfur reserves as of December 31, 1994 which
are not shown above; however, the revenue from these sulfur reserves is
included in the cash inflow data in this report.

                 The proved reserves presented in this report comply with the
SEC's Regulation S-X Part 210.4-10 Sec. (a) as clarified by subsequent
Commission Staff Accounting Bulletins, and are based on the following
definitions and criteria:

                 Proved reserves of crude oil, condensate, natural gas, and
         natural gas liquids are estimated quantities that geological and
         engineering data demonstrate with reasonable certainty to be
         recoverable in the future from known reservoirs under existing
         conditions.  Reservoirs are considered proved if economic
         producibility is supported by actual production or formation tests.
         In certain instances, proved reserves are assigned on the basis of a
         combination of core analysis and electrical and other type logs which
         indicate the reservoirs are analogous to reservoirs in the same field
         which are producing or have demonstrated the ability to produce on a
         formation test.  The area of a reservoir considered proved includes
         (1) that portion delineated by drilling and defined by fluid contacts,
         if any, and (2) the adjoining portions not yet drilled that can be
         reasonably judged as economically productive on the basis of available
         geological and engineering data.  In the absence of data on fluid
         contacts, the lowest known structural occurrence of hydrocarbons
         controls the lower proved limit of the reservoir.  Proved reserves are
         estimates of hydrocarbons to be recovered from a given date forward.
         They may be revised as hydrocarbons are produced and additional data
         become available.  Proved natural gas reserves are comprised of
         non-associated, associated, and dissolved gas.  An appropriate
         reduction in gas reserves has been made for the expected removal of
         natural gas liquids, for lease and plant fuel, and the exclusion of
         non-hydrocarbon gases if they occur in significant quantities and are
         removed prior to sale.  Reserves that can be produced economically
         through the application of improved recovery techniques are included
         in the proved classification when these qualifications are met: (1)
         successful testing by a pilot project or the operation of an installed
         program in the reservoir provides support for the engineering analysis
         on which the project or program was based, and (2) it is reasonably
         certain the project will proceed.  Improved recovery includes all
         methods for supplementing natural reservoir forces and energy, or
         otherwise increasing ultimate recovery from a reservoir, including (1)
         pressure maintenance, (2) cycling, and (3) secondary recovery in its
         original sense.  Improved recovery also includes the enhanced recovery
         methods of thermal, chemical flooding, and the use of miscible and
         immiscible displacement fluids.  Estimates of proved reserves do not
         include crude oil, natural gas, or natural gas liquids being held in
         underground storage.  Depending on the status of development, these
         proved reserves are further subdivided into:

                 (i)  "developed reserves" which are those proved reserves
                 reasonably expected to be recovered through existing wells
                 with existing equipment and operating methods, including (a)
                 "developed producing reserves" which are those proved
                 developed reserves reasonably expected to be produced from
                 existing completion intervals now open for production in
                 existing wells, and (b) "developed non-producing reserves"
                 which are those proved developed reserves which exist behind
                 the casing of existing wells which are reasonably expected to
                 be produced through these wells in the predictable future
                 where the cost of making such hydrocarbons available for
                 production should be relatively small compared to the cost of
                 a new well; and

                 (ii) "undeveloped reserves" which are those proved reserves
                 reasonably expected to be recovered from new wells on
                 undrilled acreage, from existing wells where a relatively
                 large expenditure is required, and from acreage for which an
                 application of fluid injection or other improved recovery
                 technique is contemplated where the technique has been proved
                 effective by actual tests in the area in the same reservoir.
                 Reserves from undrilled acreage are limited to those drilling
                 units offsetting productive units that are reasonably certain
                 of production when drilled.  Proved reserves for other
                 undrilled units are included only where it can be demonstrated
                 with reasonable certainty that there is continuity of
                 production from the existing productive formation.

                 Because of the direct relationship between volumes of proved
undeveloped reserves and development plans, we include in the proved
undeveloped category only reserves assigned to undeveloped locations that we
have been assured will definitely be drilled and reserves assigned to the
undeveloped portions of secondary or tertiary projects which we have been
assured will definitely be developed.

                 The Company has interests in certain tracts which have
substantial additional hydrocarbon quantities which cannot be classified as
proved and consequently are not included herein.  The Company has active
exploratory and development drilling programs which may result in the
reclassification of significant additional volumes to the proved category.

                 In accordance with the requirements of FASB 69, our estimates
of future cash inflows, future costs, and future net cash inflows before income

        Our estimates as of December 31, 1994 and 1993 of future cash inflows,
future costs, future net cash inflows before income tax, and present value at 10
percent before income tax are

shown individually for total worldwide, total United States (onshore and
offshore), and foreign areas in Table No. 2 which is attached.

                 The future cash inflows are gross revenues before any
deductions and include the British Columbia Cost of Service Allowance for
certain Canadian properties.  The production costs were based on current data
and include production taxes in the United States, certain foreign taxes where
applicable, ad valorem taxes, and certain other items such as transportation
and processing costs, and the Alberta Royalty Tax Credit where applicable, in
addition to the operating costs directly applicable to the individual leases or
wells.  The development costs were based on current data and include
dismantlement and abandonment costs net of salvage for properties where such
costs are relatively significant.

                 The Company furnished us with gas prices in effect at December
31, 1994 and with its forecasts of future gas prices which take into account
SEC guidelines, current market prices, contract prices, and fixed and
determinable price escalations where applicable.  In accordance with SEC
guidelines, the future gas prices used in this report make no allowances for
future gas price increases which may occur as a result of inflation nor do they
account for seasonal variations in gas prices which may cause future yearly
average gas prices to be somewhat different than December gas prices.  For gas
sold under contract, the contract gas price including fixed and determinable
escalations exclusive of inflation adjustments, was used until the contract
expires and then was adjusted to the current market price for the area and held
at this adjusted price to depletion of the reserves.

                 The Company furnished us with liquid prices in effect at
December 31, 1994 and these prices were held constant to depletion of the
properties.  In accordance with SEC guidelines, changes in liquid prices
subsequent to December 31, 1994 were not considered in this report.

                 The Alberta Royalty Tax Credit and the British Columbia Cost
of Service Allowance were applied in our estimates of future net income from
the Company's properties in Canada.

                 Operating costs for the leases and wells in this report were
based on the operating expense reports of the Company and include only those
costs directly applicable to the leases or wells.  When applicable, the
operating costs include a portion of general and administrative costs allocated
directly to the leases and wells under terms of operating agreements.
Development costs were furnished to us by the Company and are based on
authorizations for expenditure for the proposed work or actual costs for
similar projects.  The current operating and development costs were held
constant throughout the life of the properties.  For properties located
onshore, this study did not consider the salvage value of the lease equipment
or the abandonment cost since both are relatively insignificant and tend to
offset each other.  The estimated net cost of abandonment after salvage was
included for offshore properties where abandonment costs net of salvage are
significant.  The estimates of the offshore net abandonment costs furnished by
the Company were accepted without independent verification.  No deduction was
made for indirect costs such as general administration and overhead expenses,
loan repayments, interest expenses, and exploration and development
prepayments.  The Company supplied data on accumulated gas production
imbalances which were taken into account in our estimates of future production
and income.

                 The estimates of reserves presented herein are based upon a
detailed study of the properties in which the Company owns an interest;
however, we have not made any field examination of the properties.  No
consideration was given in this report to potential environmental liabilities
which may exist nor were any costs included for potential liability to restore
and clean up damages, if any, caused by past operating practices.  The Company
has informed us that they have furnished us all of
<PAGE>   5

the accounts, records, geological and engineering data and reports, and other
data required for this investigation.  The ownership interests, prices, and
other factual data furnished by the Company were accepted without independent
verification.  The estimates presented in this report are based on data
available through December 1994.

                 The reserves included in this report are estimates only and
should not be construed as being exact quantities.  They may or may not be
actually recovered, and if recovered, the revenues therefrom and the actual
costs related thereto could be more or less than the estimated amounts.
Moreover, estimates of reserves may increase or decrease as a result of future
operations.

                 In general, we estimate that future gas production rates will
continue to be the same as the average rate for the latest available 12 months
of actual production until such time that the well or wells are incapable of
producing at this rate.  The well or wells were then projected to decline at
their decreasing delivery capacity rate.  Our general policy on estimates of
future gas production rates is adjusted when necessary to reflect actual gas
market conditions in specific cases.  The future production rates from wells
now on production may be more or less than estimated because of changes in
market demand or allowables set by regulatory bodies.  Wells or locations which
are not currently producing may start producing earlier or later than
anticipated in our estimates of their future production rates.

                 While it may reasonably be anticipated that the future prices
received for the sale of production and the operating costs and other costs
relating to such production may also increase or decrease from existing levels,
such changes were, in accordance with rules adopted by the SEC, omitted from
consideration in making this evaluation.

                 Neither we nor any of our employees have any interest in the
subject properties and neither the employment to make this study nor the
compensation is contingent on our estimates of reserves and future cash inflows
for the subject properties.

RE:      EVALUATION OF THE INTERESTS OF PENNZOIL CANADA INC.
         EFFECTIVE DECEMBER 31, 1994


Gentlemen:

                 At your request we have prepared an estimate of the reserves,
future production and income attributable to certain leasehold and royalty
interests of Pennzoil Canada Inc. hereafter referred to as "the Company" with
an effective date of December 31, 1994.  In accordance with the requirements of
FASB 69, our estimates of the Company's net proved reserves as of December 31,
1993 and 1994 as contained in this report and our previous reports are
presented in attached Table No. 1 together with a tabulation of the components
of the differences in the estimates as of such date.  The assets evaluated
herein are attributable to the acquisition of Co-enerco Resources Ltd.

                 The estimated reserve volumes and future income amounts
presented in this report are related to hydrocarbon prices.  December, 1994
hydrocarbon prices were used in the preparation of this report as required by
Securities and Exchange Commission (SEC) and Financial Accounting Standards
Bulletin No. 69 (FASB 69) guidelines; however, actual future prices may vary
significantly from December, 1994 prices.  Therefore, volumes of reserves
actually recovered and amounts of income actually received may differ
significantly from the estimated quantities presented in this report.  Our
estimates of the proved net reserves attributable to the interests of the
Company as of December 31, 1994 are shown below:

         Developed:
             Canada                                         13,713,031               160,825

                 The "Liquid" reserves shown above are comprised of crude oil,
condensate and natural gas liquids.  Natural gas liquids (excluding condensate)
comprise 4.5 percent of the Company's developed liquid reserves and 4.7 percent
of the Company's developed and undeveloped liquid reserves.  All hydrocarbon
liquid reserves are expressed in standard 42 gallon barrels.  All gas volumes
are hydrocarbon sales gas expressed in MMcf at the pressure and temperature
bases of the area where the gas reserves are located.  In addition, the Company
owns 326 long tons of sulphur reserves as of December 31, 1994 which are not
shown above; however, the revenue from these sulphur reserves is included in
the cash inflow data in this report.

                 The proved reserves presented in this report comply with the
SEC's Regulation S-X Part 210.4-10 Sec. (a) as clarified by subsequent
Commission Staff Accounting Bulletins and are based on the following
definitions and criteria:

                 Proved reserves are those reserves estimated as recoverable
under current technology and anticipated economic conditions, from that portion
of a reservoir which can be reasonably evaluated as economically productive on
the basis of analysis of drilling, geological, geophysical and engineering
data, including the reserves to be obtained by enhanced recovery processes
demonstrated to be economically and technically successful in the subject
reservoir.

                 Proved producing reserves are those reserves that are actually
on production or, if not producing, that could be recovered from existing wells
or facilities and where the reasons for the current non-producing status is the
choice of the owner rather than the lack of markets or some other reasons.  An
illustration of such a situation is where a well or zone is capable but is shut
in because its deliverability is not required to meet contract commitments.

                 Proved non-producing reserves are those reserves that are not
currently producing either due to lack of facilities and/or markets.

                 Proved undeveloped reserves are proved reserves which are
expected to be recovered from new wells on undrilled acreage, or from existing
wells where a relatively major expenditure is required for recompletion.
Reserves on undrilled acreages are limited to those drilling units offsetting
productive units, which are reasonably certain of production when drilled.

                 Due to the direct relationship between volumes of proved
undeveloped reserves and development plans, we include in the proved
undeveloped category only reserves assigned to undeveloped locations that we
have been assured will be drilled.

                 The Company has interests in certain tracts which have been
evaluated as having probable additional hydrocarbon quantities which are not
classified as proved and consequently are not included herein.  Future
development activity may result in these reserves being reclassified as proved.

                 In accordance with the requirements of FASB 69, our estimates
of future cash inflows, future costs and future net cash inflows before income
tax as of December 31, 1994 from this report and as of December 31, 1993 are
presented below.

</TABLE>




                 Our estimates as of December 31, 1994 and 1993 of future cash
inflows, future costs, future net cash inflows before income tax, and present
value at 10 percent before income tax are shown individually for Pennzoil
Canada Inc. in Table No. 2, attached hereto.

                 The future cash inflows are gross revenues before any
deductions and include the British Columbia Cost of Service Allowance for
certain Canadian properties.  The production costs were based on current data
and include the operating costs directly applicable to the individual leases or
wells and the Alberta Gas Cost Allowance.  The development costs were based on
current data and include dismantlement and abandonment costs net of salvage for
properties where such costs are relatively significant.

                 In accordance with SEC guidelines, the future gas prices used
in this report make no allowances for future gas price increase which may occur
as a result of inflation nor do they account for seasonal variations in gas
prices which may cause future yearly average gas prices to be somewhat
different than December gas prices.  No gas contract pricing has been used
which would cause future pricing to change from the December, 1994 actual
pricing.

                 The Company has provided liquid prices in effect as at
December 31, 1994 and these prices were held constant to depletion of the
properties.  In accordance with SEC guidelines, changes in liquid prices
subsequent to December 31, 1994 were not considered in this report.

                 Operating costs for the leases and wells in this report were
based on the operating expense reports of the Company and include only those
costs directly applicable to the leases or wells.  When applicable, the
operating costs include a portion of general and administrative costs allocated
directly to the leases and wells under terms of operating agreements.
Development costs were furnished to us by the Company and are based on
authorizations for expenditure for the proposed work or actual costs for
similar projects.  In

certain circumstances, Outtrim Szabo was required to develop the capital cost
forecasts for future developments.  The current operating and development costs
were held constant throughout the life of the properties.  For all properties,
the salvage value of the lease equipment or the abandonment cost are relatively
insignificant and tend to offset each other.  No deduction was made for
indirect costs such as general administration and overhead expenses, loan
repayments, interest expenses and exploration and development prepayments.

                 The estimates of reserves presented herein are based upon a
detailed study of the properties in which the Company owns an interest;
however, we have not made any field examination of the properties.  No
consideration was given in this report to potential environmental liabilities
which may exist nor were any costs included for potential liability to restore
and clean up damages, if any, caused by past operating practices.  The Company
has informed us that they have furnished us all of the accounts, records,
geological and engineering data and reports and other data required for this
investigation.  The ownership interests, prices and other factual data
furnished by the Company were accepted without independent verification.  The
estimates presented in this report are based on data available through
December, 1994.

                 The reserves included in this report are estimates only and
should not be construed as being exact quantities.  They may or may not be
actually recovered and, if recovered, the revenues therefrom and the actual
costs related thereto could be more or less than the estimated amounts.
Moreover, estimates of reserves may increase or decrease as a result of future
operations.

                 Production forecasts were designed based on contract
information for each area, the future productive capability of each well or
evaluation entity was based on the current capability, various test data
available on the wells, adjacent control wells and similar developments in the
area.

                 While it may reasonably be anticipated that the future prices
received for the sale of production and the operating costs and other costs
relating to such production may also increase or decrease from existing levels,
such changes were, in accordance with rules adopted by the SEC, omitted from
consideration in making this evaluation.

                 Neither we nor any of our employees have any interest in the
subject properties and neither the employment to make this study nor the
compensation is contingent on our estimates or reserves and future cash inflows
for the subject properties.

                                        Yours truly,

                                        OUTTRIM SZABO ASSOCIATES LTD.
