 (1) 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. In connection with this transaction,
     Pennzoil's sulphur segment recorded a charge to depreciation, depletion and
     amortization expense ("DD&A") of $50.2 million in September 1994. The
     transaction was completed in January 1995. Pennzoil continues to operate
     its related international sulphur business. Beginning with January 1995,
     the results of such operations are included in other segment operating
     income. Reference is made to "Management's Discussion and Analysis of
     Financial Condition and Results of Operations -- Sulphur" and Note 10 of
     Notes to Consolidated Financial Statements for additional information.
 
 (2) For 1995 and 1994, 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.
 
 (3) Substantially all intersegment sales, which are priced at market, are
     from the oil and gas segment to the motor oil and refined products segment.
 
 (4) 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 PEPCO (at the time
     named Pennzoil Petroleum Company) capital stock for financial reporting
     purposes and, therefore, the carrying value of PEPCO's oil and gas
     properties by $390.3 million, and such increased investment resulted in a
     $93.9 million increase in DD&A recognized in October 1994 relating to
     PEPCO's oil and gas properties from the date of the acquisition of PEPCO 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 DD&A 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 Note 8 of Notes to
     Consolidated Financial Statements for additional information.
 
 (5) As of September 30, 1994, PPC ceased processing 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 DD&A.
 
 (6) Effective July 1, 1995, Pennzoil adopted the requirements of Statement of
     Financial Accounting Standards ("SFAS") No. 121, "Accounting for the
     Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
     Of." As a result, Pennzoil recorded a pretax charge of $399.8 million as of
     July 1, 1995 to reflect the impairment of long-lived assets. Included in
     the pretax charge of $399.8 million for the impairment of long-lived assets
     were charges related to the oil and gas, motor oil and refined products,
     franchise operations and corporate segments of $378.9 million, $3.5
     million, $3.5 million and $13.9 million, respectively. Charges for the
     impairment of long-lived assets resulting from the adoption of SFAS No. 121
     have not been included in DD&A in the table above. Reference is made to
     "Management's Discussion and Analysis of Financial Condition and Results of
     Operations -- Oil and Gas" and Note 1 of Notes to Consolidated Financial
     Statements for additional information.
 
 (7) Includes interest capitalized of $4,231,000, $9,027,000 and $11,420,000 in
     1995, 1994 and 1993, respectively.
 
 (8) 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. Capital expenditures for 1994 do not include any
     amounts paid with respect to the IRS settlement discussed in footnote (4)
     above.
 
 (9) For 1995, capital expenditures for the motor oil & refined products segment
     include $598,000 allocated to property, plant and equipment added as a
     result of PPC's acquisition of the assets of the Viscosity Oil division
     ("Viscosity Oil") of Case Corporation ("Case"). Reference is made to
     "Management's Discussion and Analysis of Financial Condition and Results of
     Operations -- Motor Oil & Refined Products" and Note 10 of Notes to
     Consolidated Financial Statements for additional information.

     Narrative descriptions of these business segments follow, with emphasis on
1995 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 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 Co-enerco
subsequent to June 30, 1994 have been included in Pennzoil's consolidated

     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 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, 1995, 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 and Outtrim Szabo on the reserve
estimates as of December 31, 1994, and the summary reports of Ryder Scott on the
reserve estimates as of December 31, 1993 are included in Pennzoil's previously
filed Annual Reports on Form 10-K.
 
     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) Included in 1995 reserves are 1 million barrels of crude oil, condensate
     and natural gas liquids and 5 Bcf of natural gas attributable to an
     operating service agreement in Venezuela between Maraven, S.A., a Petroleos
     De Venezuela S.A. affiliate, and a joint venture between Pennzoil Venezuela
     Corporation, S.A., an indirect wholly owned subsidiary of Pennzoil, and
     Vinccler S.A. Under this agreement, all mineral rights are owned by the
     government of Venezuela. Reference is made to "Management's Discussion and
     Analysis of Financial Condition and Results of Operations -- Oil and Gas"
     for additional information.
 
 (2) United States natural gas reserves for 1995, 1994 and 1993 exclude 156 Bcf,
     161 Bcf and 162 Bcf, respectively, of carbon dioxide gas for sale or use in
     Pennzoil's operations.

(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) 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.
 
     In April 1995, Pennzoil Gas Marketing Company, an indirect wholly owned
Pennzoil subsidiary, and BRING Gas Services Corp., a subsidiary of Brooklyn
Union Gas Co., formed PennUnion Energy Services, L.L.C. ("PennUnion"), a 50-50
gas marketing joint venture. Pennzoil contributed $3.7 million in cash to
PennUnion. Pennzoil has committed over 90% of its natural gas production from
the continental United States through March 31, 1998 to be marketed by
PennUnion. PennUnion's natural gas marketing efforts are primarily constrained
only by normal free marketplace competition and by regulatory limitations
described generally below under the caption "Government Regulation."
 
     Pennzoil has a price risk management program that permits utilization of
agreements and financial instruments (such as futures, forward and option
contracts and swaps and collars) to reduce the price risk associated with
fluctuations in crude oil and natural gas prices. Reference is made to
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Capital Resources and Liquidity" for additional information.
 
     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, 1995, Pennzoil was participating in the drilling or
awaiting completion of 23 gross (22.2 net) wells onshore and 11 gross (8.9 net)
wells offshore the United States.

     NORTH AMERICA -- ASSET HIGHGRADING PROGRAM. During 1995, Pennzoil continued
its assessment of its domestic oil and gas properties and its related asset
highgrading program commenced in 1992. This assessment has resulted in the
categorization of Pennzoil's oil and gas properties into core and noncore
producing areas and core and noncore producing fields within core areas, and the
disposition of substantially all properties and fields categorized as noncore
assets.
 
     From the beginning of 1992 through 1995 Pennzoil disposed of approximately
600 producing oil and gas fields, including approximately 150 fields in 1995.
The fields disposed of in 1995 primarily consisted of noncore properties in the
Gulf of Mexico, Permian Basin, Mid-Continent and Gulf Coast. The noncore assets
disposed of over the four-year period would have represented less than 12% of
the reported value of Pennzoil's current proven oil and gas reserves and did not
factor into Pennzoil's future reserve development plans. After completion in the
first quarter of 1996 of currently pending transactions, Pennzoil, through
acquisitions, sales and trades of interests in producing oil and gas fields,
will have approximately 100 core oil and gas properties in the United States and
will have substantially completed its asset highgrading program and the related
disposition of noncore assets. Reference is made to "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Oil and Gas" for
additional information.
 
     NORTH AMERICA -- PRODUCTION COSTS. Oil and gas production volumes decreased
in 1995 primarily as a result of the disposal of noncore assets. During 1995,
Pennzoil produced an average of approximately 178,000 barrels of oil equivalent
("BOE") per day compared to an average of approximately 188,000 BOE per day
during 1994, including almost 15,000 BOE per day of production associated with
properties sold during 1995. Total production costs and expenses per BOE,
excluding exploration expense and DD&A, were reduced from $5.93 in 1993 to $5.32
in 1994 and to $5.09 in 1995.
 
     NORTH AMERICA -- EXPLORATION, DEVELOPMENT AND PRODUCTION ACTIVITIES. In the
Gulf of Mexico, Pennzoil owns a 70% working interest in South Marsh Island Block
35 and completed a well in November 1995 with initial production of
approximately 10 million cubic feet ("MMcf") per day of natural gas. Pennzoil
began projects in 1995 on South Marsh Island Block 23 that are expected to
increase production by approximately 35 MMcf per day of natural gas by mid-1996.
Pennzoil also holds a 100% working interest in a multi-well development program
and facility modification at Ship Shoal Block 154. Pennzoil's current
redevelopment of this field should increase production from less than 100
barrels per day of liquids to approximately 7,000 barrels per day of liquids and
18 MMcf per day of natural gas by mid-1996. Additionally, a discovery well
drilled at West Cameron Block 580, where Pennzoil has a 75% working interest,
encountered a significant gas discovery. Facilities are currently under
construction, and production of approximately 70 MMcf per day of natural gas and
3,000 barrels per day of liquids should commence during the second half of 1996.
In December 1995, Pennzoil began drilling a subsalt test well in South Marsh
Island Block 97. Pennzoil is the operator and has a 50% working interest. In
deepwater, Pennzoil has a 20% working interest in the Shell Oil Company operated
Garden Banks Block 127/128 subsalt natural gas discovery. The field should begin
production in 1997, with peak rates estimated to reach 250 to 300 MMcf per day
of natural gas in 1998.
 
     Onshore, a 3-D seismic program begun in 1994 led to a significant gas
discovery in 1995 in the Tinsley Field in Mississippi. Two wells were drilled,
and a third is planned for the first half of 1996. Initial production in the
second quarter of 1996 is expected to be approximately 15 MMcf per day of
natural gas and 1,000 barrels per day of liquids. Pennzoil has an approximate
92% working interest in the prospective area. In Quarantine Bay, Louisiana,
Pennzoil has a 100% working interest in four wells drilled in 1995 that are
currently producing 5 MMcf per day of natural gas and 1,000 barrels per day of
liquids. Two additional wells are currently planned to be drilled in the first
half of 1996. In addition, during 1995, Pennzoil increased its interest in the
SACROC Unit in West Texas and initiated a major redevelopment program. Gross
production of liquids increased 2,000 barrels per day during the last three
months of 1995.
 
     INTERNATIONAL. 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 deepwater portion of the Gunashli fields in the Caspian Sea.
The contract was ratified by the Azerbaijan Parliament 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
 
                                        8
<PAGE>   10
 
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 members of
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. Current members of the consortium and their respective interests are
SOCAR (10.00%), Amoco (17.01%), British Petroleum (17.127%), Delta-Nimir
(1.68%), Exxon (5.00%), LUKoil (10.00%), McDermott (2.45%), Pennzoil (9.82%),
Ramco (2.08%), Statoil (8.563%), Turkish Petroleum Company (6.75%) 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,
50% of which has already been paid. Reference is made to "Management's
Discussion and Analysis of Financial Condition and Results of Operations -- Oil
and Gas" for additional information.
 
     In September 1995, the consortium elected to pursue dual export routes for
transporting early oil production from the Caspian Sea, one north through an
existing pipeline system to a Russian port on the Black Sea, and the second west
through Azerbaijan and Georgia to the Black Sea. The western route will require
construction of 73 miles of pipeline to interconnect existing lines. All
necessary treaties and commercial agreements between governments and the western
companies for the northern route became effective in February 1996. Spending on
the early oil project will begin to accelerate as a result of these actions.
Pennzoil has recorded 14 million barrels of crude oil reserves relating to early
oil from this project.
 
     In November 1995, Pennzoil announced that its Pennzoil Caspian Development
Corporation subsidiary had entered into a definitive exploration, development
and production sharing contract with SOCAR covering the Karabakh prospect in the
Caspian Sea offshore Azerbaijan. Participating in the project with Pennzoil
(30%) are units of LUKoil of Russia (7.5%), Agip of Italy (5%) and LUKAgip, a
subsidiary of LUKoil and Agip (50%). In addition, a commercial affiliate of
SOCAR has a 7.5% interest as a contractor party. The exploration, development
and production sharing agreement was ratified by the Azerbaijan Parliament on
February 13, 1996. The Karabakh prospect is located north of the
Azeri-Chirag-Gunashli deepwater unit and outside the Apsheron trend
approximately 50 miles offshore in approximately 600 feet of water. The work
commitment will include a seismic program and exploratory drilling over a period
of three years, which period may be extended an additional one-and-a-half years.
Should commercial hydrocarbons be discovered, the agreement will have a
development and production period of 25 years, which may be extended an
additional 5 years under certain conditions.
 
     Also in Azerbaijan, Pennzoil had completed work in 1994 on a comprehensive
gas gathering and compression system to capture, compress and transport to shore
approximately 150 MMcf per day of natural gas previously being vented from the
Gunashli field. As of December 31, 1995, over one-quarter of Pennzoil's
investment in the gas utilization project had been recovered through credit
toward Pennzoil's portion of bonus payments made to the government of Azerbaijan
with respect to the Karabakh prospect and the Azeri-Chirag-Gunashli fields,
direct payments from SOCAR during 1995 and other credits. Pennzoil's remaining
investment in the gas utilization project will be reimbursed through future
payments from SOCAR funded by bonus payments to be made by other participants in
the Karabakh prospect and in the Azeri-Chirag-Gunashli fields and additional
credits toward Pennzoil's future bonus payments with respect to the
Azeri-Chirag-Gunashli fields.
 
     In July 1995, a joint venture between Pennzoil Venezuela Corporation, S.A.,
an indirect wholly owned subsidiary of Pennzoil, and Vinccler S.A. entered into
an operating service agreement with Maraven, S.A., a Petroleos De Venezuela S.A.
affiliate, to operate the East Falcon Unit in northwestern Venezuela. This unit
includes an oil field in which production operations were suspended in 1968, two
undeveloped gas fields and several prospects. Under this service agreement,
Pennzoil is required to incur all costs attributable to exploration, development
and production activities. The service agreement allows for Pennzoil to recover
such costs through a per-barrel fee for operating this unit, which contains
estimated gross proved remaining reserves available through field reactivation
of 12 million BOE. Early production should begin by mid-1996 and is estimated to
reach about 2,000 barrels per day of liquids by the end of 1996.
 
     In September 1995, Pennzoil and Forum Exploration Co. ("Forum
Exploration"), an independent Egyptian oil company, signed a farm-in agreement
giving Pennzoil an 87.5% working interest in Forum Exploration's South-West
Gebel El-Zeit concession in the southern Gulf of Suez, offshore Egypt. Pennzoil
 
                                        9
<PAGE>   11
 
Egypt, Inc. ("Pennzoil Egypt"), an indirect wholly owned subsidiary of Pennzoil,
will be the operator for this farm-in agreement. The Pennzoil/Forum Exploration
group is committed to a minimum of $3 million in exploration expenditures over
the next three years. An additional phase, which is at the option of the
Pennzoil/Forum Exploration group, would consist of three additional years of
exploration with a minimum expenditure of $5 million. Seismic activity is
currently in progress.
 
     Late in 1995, Pennzoil and a subsidiary of Agip of Italy were awarded the
West Feiran Block in the Gulf of Suez. Each company has a 50% interest. The West
Feiran Block, equivalent to 17 Gulf of Mexico blocks, lies in the east central
part of the Gulf of Suez and is surrounded by several giant oil fields.
Ratification by the Egyptian Parliament is expected in the first half of 1996.
 
     CAPITAL BUDGET. Pennzoil's capital budget currently provides that its
capital expenditures, including interest capitalized, for domestic and
international oil and gas exploration and development during 1996 are estimated
to be $232.8 million, compared to $297.6 million of capital expenditures in
1995. Reference is made to "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Capital Resources and Liquidity" for
additional information.
 
     OPERATING RISKS. 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 operations 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 country 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 processing crude oil at its refinery
in Roosevelt, Utah. PPC continues to purchase crude oil from the
Bluebell-Altamont Field and other nearby fields in Utah and maintains a
transportation terminal at the refinery site.

(1) Processed volumes and refinery utilization are lower in 1995 primarily due
    to the Rouseville refinery fire which occurred in the fourth quarter and to
    an extended maintenance turnaround at the Atlas refinery which occurred in
    the fourth quarter.
 
(2) As of September 30, 1994, PPC ceased processing crude oil at its refinery in
    Roosevelt, Utah.
 
     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.
 
     In June 1994, PPC and Conoco, Inc. ("Conoco") commenced work on a joint
venture project at Conoco's refinery in Lake Charles, Louisiana. Operating
through a 50-50 joint venture partnership called Excel Paralubes, the companies
are constructing a new, state-of-the-art lube oil hydrocracker facility
estimated to cost approximately $500 million, which is being funded with project
financing. The facility will produce approximately 18,000 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 late 1996, with operations commencing in early 1997. Conoco is
acting as construction manager and operator of the plant with support positions
staffed by both companies. The facility will be a low cost producer of high-
quality base oils and is intended to make PPC self-sufficient in high-quality
lube base stocks. Additionally, construction 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 April 1995, PPC and the Polymers Division of Petrolite Corporation
("Petrolite") formed a 50-50 partnership called BARECO(R) Products to market a
broad line of wax products to domestic and international purchasers of paraffin,
microcrystalline and related synthetic waxes. Pennzoil transports partially
refined
 
                                       11
<PAGE>   13
 
feedstock from Utah to its Rouseville refinery, which produces 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, are marketed through the partnership. Pennzoil is investing more
than $23 million in its Rouseville refinery and its packaging plant in nearby
Reno, Pennsylvania in connection with this venture.
 
     In July 1995, PPC agreed to purchase a one-third ownership interest in a
manufacturing and marketing company located in Caracas, Venezuela. The company,
Aceites y Solventes Venezolanos Vassa S.A., has constructed and is commissioning
a facility in Cardon, Venezuela to manufacture white oils, solvents, and
transformer oils for sale primarily in South America, Central America and the
Caribbean. Pennzoil's capital investment will be approximately $14.5 million, a
portion of which will be funded through nonrecourse project financing.
 
     In July 1995, PPC and a joint venture partner began work on a project to
build and operate a liquids terminal at the Port of Shreveport, Louisiana. The
opening of the Red River to navigation has provided the opportunity for PPC to
use less expensive waterborne freight for access to new feedstocks and markets
for the Atlas refinery and PPC's Shreveport packaging facility. Completion is
planned for October 1996.
 
     In October 1995, an explosion and fire occurred at PPC's Rouseville
refinery. Two PPC employees and three contractor employees were killed. Several
other injuries were reported. As of the date hereof, results of Occupational
Safety and Health Administration ("OSHA") investigations have not been released.
The major damage identified was to the tanks, piping and electrical lines in the
area of the fire. Some portions of the new wax plant project were damaged, and
project completion has been delayed until August 1996. Reference is made to Note
8 of Notes to Consolidated Financial Statements for additional information.
 
     MARKETING. PENNZOIL(R) motor oil and lubricants are produced in five
domestic company-owned and operated blending and packaging plants (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 152 independent
distributors and 58 company-owned distribution facilities. Additionally,
PENNZOIL(R) brand gasoline is marketed through approximately 393 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.
 
     PPC is 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 through retail channels, but GUMOUT(R) has an
increasing presence in the installed market (fast lubes, service stations, auto
dealers, etc.). WOLF'S HEAD(R) lubricants are also marketed as a secondary
value-priced line throughout the U.S., alongside the PENNZOIL(R) lubricants
brand. In addition, PPC is a master distributor for GOJO(R) hand cleaner
products, PRESTONE(R) antifreeze and FRIGC(R) FR-12[TM] refrigerant.
 
     In September 1995, PPC acquired the assets of the Viscosity Oil division of
Case for $33.6 million. Viscosity Oil is a leading supplier of premium-quality
lubricants to the North American off-road industry, and it supplies lubricants
to substantially all the Case dealer network, with locations in all 50 states
and Canada. In addition, Viscosity Oil supplies virtually all of the
factory-fill lubricants for Case's North American manufacturing plants. As part
of the acquisition, a long-term supply agreement was entered into whereby
Pennzoil will supply the aftermarket lubricant products that Case will continue
to sell to its dealerships. The agreement also calls for Pennzoil to supply
factory-fill lubricants to Case.
 
     PENNZOIL(R) motor oil and lubricants are marketed in 62 countries through
44 distributors, three licensees, four joint ventures and ten company-owned
marketing distribution centers.

     International expansion continued in 1995 with PPC signing joint venture
contracts in Peru, Argentina and China. PPC also reached a tentative agreement
to increase its ownership position in its Indian joint venture, subject to
government approval. PPC's licensee in Indonesia began production at a new
refining, blending and packaging plant during 1995. PPC continued to experience
volume growth in most international markets including Australia, Canada, Mexico
and the Far East region.
 
     In December 1995, PPC formed a 50-50 joint venture with Lithcon Petroleum
Inc. ("Lithcon") in Tianjin, China to form a lubricants manufacturing and
marketing company. Marketing of lubricants imported from the U.S. is set for the
first quarter of 1996 with local production planned for the third quarter.
Earlier in 1995, Pennzoil, Lithcon and SINOPEC Yue Hua (Zhuhai) Petrochemical
Company, a marketing arm of SINOPEC, the Chinese government oil company, formed
a joint venture to produce and market Pennzoil aftermarket fuel additives in
eight southern provinces in China.
 
     In December 1995, PPC purchased a 45% equity share in Isopetrol S.A., a
lubricants marketing and manufacturing company located in Lima, Peru. This
investment will allow PPC to increase its access to Peru and neighboring
markets. In addition, the agreement provides PPC an ownership interest in a
lubricants blending, packaging and grease plant located in Callao, Peru.
 
     In December 1995, PPC announced that it had selected Frankfurt, Germany as
the site for its European headquarters. All European operations will be managed
from the Frankfurt, Germany headquarters. PPC will create a new European
division apart from its existing divisions in the United States. In addition,
Pennzoil will consolidate its production facilities in Europe in its plant in
Barcelona, Spain during 1996. The facility in Barcelona will supply all of PPC's
current requirements in Europe. As a result of the consolidation of production,
Pennzoil plans to sell its plant in Zaandam, Netherlands, which has been
reporting losses for several years.
 
     PPC considers the 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 PPC's marketing and manufacturing operations during the years
indicated.

FRANCHISE OPERATIONS
 
     Jiffy Lube franchises, owns and operates automotive service centers. JIFFY
LUBE(R) service centers offer convenient automotive maintenance services. Jiffy
Lube's standard full service includes an oil change and filter replacement,
chassis lubrication, checking for proper tire inflation, window washing,
interior vacuuming, checking and topping off of transmission, differential,
windshield washer, battery and power steering fluid levels and air filter and
windshield wiper blade examination. JIFFY LUBE(R) service centers also provide
other authorized services and products at additional cost.
 
     In March 1995, Jiffy Lube and the Sears Merchandise Group ("Sears") agreed
to open fast-oil change units in Sears Auto Centers over the next three years.
Under the agreement, Jiffy Lube remodels, equips and operates service areas
within Sears Auto Centers, while Sears continues to utilize the remaining bays
for its operations. As a first step, Sears and Jiffy Lube have agreed to set up
approximately 240 Jiffy Lube-owned and franchised centers and had 28 centers
open at the end of 1995.
 
     At December 31, 1995, 1,207 JIFFY LUBE(R) service centers were open
worldwide, including 1,198 in the United States. Domestically, franchisees
operated 721 of the service centers and Jiffy Lube owned and

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 operate its international sulphur business. Reference is made to

</TABLE>
 
     The decrease in employees between December 31, 1994 and 1995 is primarily
attributable to a workforce reduction program and the disposition of Pennzoil's
domestic sulphur operations. The increase in employees between December 31, 1993
and 1994 is primarily attributable to an increase in the number of company-owned
service centers in the franchise operations segment.
 
     Approximately 8% 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, 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
nonpipeline 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, FERC
issued numerous individual pipeline orders in highly contested proceedings. As a
result, numerous appeals of these orders are now pending, and
 
                                       15
<PAGE>   17
 
Pennzoil cannot predict what action the reviewing courts or FERC may take on
these matters. Under current arrangements, however, the marketing flexibility of
nonpipeline 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

     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 1990 Amendments to
the Clean Air Act 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 obligates 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
("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. 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.
 
                                       16
<PAGE>   18
 
     Pennzoil's assessment of the potential impact of these environmental laws
is subject to uncertainty due to the difficult process of estimating remediation
costs that are subject to ongoing and evolving 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 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 is subject to the ongoing development of
remediation technologies. Pennzoil's assessment analysis takes into account the
condition of each site 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 $101.9 million have been made by Pennzoil
since January 1993 with respect to environmental protection. Capital
expenditures for environmental control facilities are currently expected to be
approximately $27 million in 1996. 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 filed in
1974 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, a
former Pennzoil subsidiary, to its customers.
 
     (B) CLASS ACTION. In April 1994, a lawsuit styled Lazy Oil, Inc. vs. Witco
Corporation; Quaker State Corporation; and Pennzoil Company, was filed in the
United States District Court for the Western District of Pennsylvania. Three
other suits, Andreassi vs. Witco Corporation; Quaker State Corporation; and
Pennzoil Company, and Thomas A. Miller Oil vs. Witco Corporation; Quaker State
Corporation; and Pennzoil Company, and Wynnewood Drilling Associates v. Witco
Corporation; Quaker State Corporation; Quaker State Oil Refining Corporation;
Pennzoil Company; and Pennzoil Products Company, were also filed in 1994,
containing allegations substantially identical to those in the Lazy Oil case.
All four suits have been consolidated for discovery and trial. The consolidated
case, styled Lazy Oil Co., John B. Andreassi and Thomas A. Miller Oil Co. on
behalf of themselves and other similarly situated vs. Witco Corporation; Quaker
State Corporation; Quaker State Oil Refining Corp.; Pennzoil Company and
Pennzoil Products Company is currently pending in the United States District
Court for the Western District of Pennsylvania, Erie Division. This class action
suit brought by purchasers of "Penn Grade crude" alleges that, from 1981 to
1995, the defendants engaged in a combination and conspiracy in unreasonable
restraint of trade in violation of Section 1 of the Sherman Act, by allegedly
acting to fix, lower, maintain and stabilize the purchase price of "Penn Grade
crude" sold by the plaintiffs and the other class members to the defendants. The
plaintiffs also allege that the defendants have fraudulently concealed their
alleged combination and conspiracy. The plaintiffs seek injunctive relief,
alleged damages sustained by the plaintiffs and the class members and recovery
of attorneys' fees and costs. Plaintiffs' motion for class certification was not
opposed by defendants, and the Court has certified a class of plaintiffs
consisting of all persons who sold "Penn Grade crude" to any of the defendants
between 1981 and June 30, 1995. Quaker State and the plaintiffs have agreed on a
proposed settlement of
 
                                       17
<PAGE>   19
 
$4.4 million payable by Quaker State, which is pending before the court for
approval. Pennzoil is contesting the case vigorously.
 
     (c) RAMCO DISPUTE. In October 1995, PEPCO, Pennzoil International, Inc.,
Pennzoil Caspian Corporation and Pennzoil Caspian Development Corporation filed
an action, styled Pennzoil Exploration and Production Company, et al. v. Ramco
Energy Limited and Ramco Hazar Energy Limited, in the United States District
Court for the Southern District of Texas, Houston Division, against Ramco Hazar
Energy Limited, formerly known as Ramco Energy Limited (collectively "Ramco").
The federal suit seeks to compel Ramco to arbitrate certain disputes that have
arisen between it and the Pennzoil plaintiffs pursuant to the Federal
Arbitration Act and the Convention on the Recognition and Enforcement of Foreign
Arbitral Awards. The underlying dispute involves Ramco's asserted claim to an
interest in the Karabakh prospect, an oil and gas field located in the
territorial waters of the Azerbaijan Republic in the Caspian Sea and which
Pennzoil Caspian Development Corporation, SOCAR and other foreign oil companies
have agreed to explore and develop. After the filing of the federal action, the
Pennzoil plaintiffs filed an Original Petition for Declaration Relief in the
281st Judicial District Court of Harris County, Texas. The state suit, styled
Pennzoil Exploration and Production Company, et al. v. Ramco Energy Limited and
Ramco Hazar Energy Limited, which is expressly conditioned upon a determination
in the federal suit that the disputes between the Pennzoil plaintiffs and Ramco
are not subject to arbitration, seeks a declaration that the Pennzoil plaintiffs
have not breached any agreements with Ramco, and do not owe and/or have not
breached any fiduciary or other legal duty to Ramco including, without
limitation, a duty of good faith and fair dealing. In November 1995, Ramco
asserted a counterclaim in the state court action, asserting breach of contract
and breach of fiduciary duties. The counterclaim seeks a declaratory judgment
granting Ramco a participation interest in the Karabakh prospect, compensatory
damages, exemplary damages, attorney's fees, costs of court and other
unspecified relief. In January 1996, the judge in the federal suit granted in
part the Pennzoil plaintiffs' motion to compel arbitration and ordered
arbitration to be held in Stockholm, Sweden. The Pennzoil plaintiffs and the
Ramco defendants have each asked the judge to reconsider portions of his order.
The court has not ruled upon the motions for reconsideration.

 (1) Reference is made to Notes 1 and 8 of Notes to Consolidated Financial
     Statements.
 
 (2) Represents results of Purolator Products Company, which was sold in 1992.
 
 (3) 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 per share, in 1992.
 
 (4) Reference is made to Note 6 of Notes to Consolidated Financial Statements
     for discussion of 1994 events. 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. 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 December 1991, Pennzoil announced its
     decision to change its method of accounting for postretirement benefit
     costs other than pensions by adopting 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.
 
 (5) As of December 31, 1995, borrowings under Pennzoil's commercial paper and
     short-term variable-rate credit arrangements totaled $468.9 million, all of
     which has been classified as long-term debt. Pennzoil does not intend or
     expect to use working capital in 1996 for the settlement of these
     borrowings and Pennzoil has the ability, by using existing revolving credit
     arrangements, to refinance this short-term debt on a long-term basis.
     Similar borrowings were reflected as short-term debt in prior years.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS.
 
     Reference is made to Industry Segment Financial Information included in
Item 1, Business and Item 2, Properties and the Consolidated Financial
Statements beginning on page F-3 for additional information.
 
RESULTS OF OPERATIONS
 
     A net loss of $305.1 million, or $6.60 per share, was recorded for 1995
compared to a net loss of $288.7 million, or $6.27 per share, for 1994 and net
income of $141.9 million, or $3.36 per share, for 1993.
 
     Effective July 1, 1995, Pennzoil adopted the requirements of SFAS No. 121.
As a result, Pennzoil recorded a charge of $265.5 million ($399.8 million before
tax), or $5.74 per share, as of July 1, 1995 to reflect the impairment of
long-lived assets, which included charges of $378.9 million before tax related
to the impairment of certain proved oil and gas properties. Reference is made to
"-- Oil and Gas" and Note 1 of Notes to Consolidated Financial Statements for
additional information.
 
     In October 1995, Pennzoil announced a cost reduction program to reduce
general and administrative expenses. As a result of this program, Pennzoil
recorded a charge of $19.9 million in December 1995 associated with a workforce
reduction.
 
     Results for 1994 include net charges of $210.4 million ($388.2 million
before tax), or $4.57 per share, associated with the settlement of a dispute
with the 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 PPC'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 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 "-- Sulphur" for
additional information related to Pennzoil's sale of its domestic sulphur
assets.
 
     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." 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 a change in
accounting principle for the periods prior to 1994.
 
     In November 1993, Pennzoil sold 8,158,582 shares of 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 1993, Pennzoil redeemed an aggregate of $388.6 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 $18.4
million ($28.3 million before tax), or $.44 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.
 
     Investment and other income, net, for 1995 and 1994 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, 1995 (Chevron
effected a "two-for-one" split of its 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
 
     Results of Operations. The oil and gas segment recorded operating income of
$92.0 million in 1995, excluding $378.9 million associated with the SFAS No. 121
impairment, but including $1.0 million in other nonrecurring net charges. This
compares with an operating loss of $4.9 million in 1994, which included $93.9
million related to the settlement of a tax dispute with the IRS, and other
nonrecurring net charges totaling $36.8 million. Operating income in 1993 was
$159.2 million. After adjustment for nonrecurring items, operating income was
down $34.8 million in 1995 compared to 1994. This was primarily due to a $78.4
million reduction in aggregate natural gas realizations due to lower natural gas
prices, partially offset by a $36.3 million reduction in operating expenses and
a $9.8 million increase in aggregate liquids price realizations. Total
production costs and expenses per BOE, excluding exploration expense and DD&A,
were reduced from $5.93 in 1993 to $5.32 in 1994 and to $5.09 in 1995.
 
     Effective July 1, 1995, Pennzoil adopted the requirements of SFAS No. 121,
which is intended to establish more consistent accounting standards for
measuring the recoverability of long-lived assets. In certain instances, SFAS
No. 121 specifies that the carrying values of assets be written down to fair
values, which, for Pennzoil, resulted in write-downs of proved oil and gas
properties that were not required under its prior impairment policy. In
determining whether an asset is impaired under the new standard, assets are
required to be grouped at the lowest level for which there are identifiable cash
flows that are largely independent of the cash flows of other groups of assets.
On this basis, certain proved oil and gas fields in North America were deemed to
be impaired because they were not expected to individually recover their entire
carrying value. However, SFAS No. 121 does not allow for the write-up of proved
oil and gas fields which are expected to individually recover more than their
carrying value. The pretax charge for the asset impairment of Pennzoil's proved
oil and gas properties was $378.9 million. The fair values used in calculating
the write-down required for such properties were determined by using the present
value of expected future cash flows or estimates of market value based on
transactions for comparable properties, as appropriate. Prior to the adoption of
SFAS No. 121, Pennzoil periodically reviewed the carrying amounts of proven
properties and an impairment reserve was provided as conditions warranted.
Reference is made to "Supplemental Financial and Statistical
Information -- Unaudited -- Oil and Gas Information" for information on the
standardized measure of discounted future net cash flows relating to proved oil
and gas reserves.
 
     As a result of the IRS settlement in October 1994, Pennzoil increased the
balance of its investment in PEPCO (at the time named Pennzoil Petroleum
Company) capital stock for financial reporting purposes and, therefore, the
carrying value of PEPCO's oil and gas properties by $390.3 million, and such
increased investment resulted in a $93.9 million increase in DD&A recognized in
October 1994 relating to PEPCO's oil and gas properties from the date of the
acquisition of PEPCO 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 DD&A adjustments related to
the IRS settlement reduced Pennzoil's 1994 pretax income by $388.2 million.
Reference is made to Note 8 of Notes to Consolidated Financial Statements for
additional information.
 
     DD&A in 1994 and 1993 included 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.
 
     Oil and gas production volumes decreased approximately 6% for 1995 compared
to 1994. The decrease in production volumes was primarily due to the sale of
noncore oil and gas assets. Natural gas produced for sale in 1995 was 662,311
Mcf per day, compared with 716,962 Mcf per day and 649,399 Mcf per day in 1994
and
 
                                       22
<PAGE>   24
 
1993, respectively. Realized natural gas prices averaged $1.46 per Mcf in 1995
compared to $1.79 per Mcf in 1994 and $2.04 per Mcf in 1993. Liquids volumes in
1995 were 67,143 barrels per day, compared to 68,709 and 64,273 barrels per day
in 1994 and 1993, respectively. Liquids prices received in 1995 averaged $14.31
per barrel, compared with $13.74 per barrel in 1994 and $14.90 per barrel in
1993.
 
     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 a price risk management program that permits utilization of
agreements and financial instruments (such as futures, forward and option
contracts and swaps and collars) to reduce the price risk associated with
fluctuations in crude oil and natural gas prices. Reference is made to
"-- Capital Resources and Liquidity" for additional information.
 
     During 1995, Pennzoil continued its assessment of its domestic oil and gas
properties and its related asset highgrading program commenced in 1992. This
assessment has resulted in the categorization of Pennzoil's oil and gas
properties into core and noncore producing areas and core and noncore producing
fields within core areas, and the disposition of substantially all properties
and fields categorized as noncore assets. From the beginning of 1992 through
1995, Pennzoil disposed of approximately 600 producing oil and gas fields,
including approximately 150 fields in 1995. Proceeds from the sales of these
noncore assets in 1995 totaled $164.8 million, resulting in gains of $9.7
million.
 
     Expenses associated with exploration activities in 1995 were $39.8 million
compared with $61.0 million in 1994 and $70.7 million in 1993. Exploration
expenses in 1995 decreased $21.2 million compared to 1994. Dry hole charges were
down $17.1 million and impairments of unproved property costs were down $5.6
million from the prior year. The decrease in dry hole expense for 1995 compared
to 1994 was primarily due to a higher percentage of successful wells drilled.
 
     Operating results for 1995 include charges totaling $9.1 million for
workforce reduction expenses resulting from a general and administrative cost
reduction program announced in October 1995 and workforce reduction expenses
during 1995 that were identified prior to the October program.
 
     Operating results for 1994 include 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 noncore assets.
 
     In April 1995, Pennzoil Gas Marketing Company, an indirect wholly owned
Pennzoil subsidiary, and BRING Gas Services Corp., a subsidiary of Brooklyn
Union Gas Co., formed PennUnion, a 50-50 gas marketing joint venture. Pennzoil
contributed $3.7 million in cash to PennUnion. Pennzoil has committed over 90%
of its natural gas production from the continental United States through March
31, 1998 to be marketed by PennUnion. Pennzoil earned pretax operating income of
approximately $.8 million related to its share of PennUnion's operating earnings
in 1995.
 
     Exploration, Development and Production Activities. In July 1995, a joint
venture between Pennzoil Venezuela Corporation, S.A., an indirect wholly owned
subsidiary of Pennzoil, and Vinccler S.A. entered into an operating service
agreement with Maraven, S.A., a Petroleos De Venezuela S.A. affiliate, to
operate the East Falcon Unit in northwestern Venezuela. This unit includes an
oil field in which production operations were suspended in 1968, two undeveloped
gas fields and several prospects. Under this service agreement, Pennzoil is
required to incur all costs attributable to exploration, development and
production activities. The service agreement allows for Pennzoil to recover such
costs through a per-barrel fee for operating this unit, which contains estimated
gross proved remaining reserves available through field reactivation of 12
million BOE. Early production should begin by mid-1996 and is estimated to reach
about 2,000 barrels per day of liquids by the end of 1996.
 
     In September 1995, Pennzoil and Forum Exploration, an independent Egyptian
oil company, signed a farm-in agreement giving Pennzoil an 87.5% working
interest in Forum Exploration's South-West Gebel El-Zeit concession in the
southern Gulf of Suez, offshore Egypt. Pennzoil Egypt, an indirect wholly owned
subsidiary of Pennzoil, will be the operator for this farm-in agreement. The
Pennzoil/Forum Exploration group is committed to a minimum of $3 million in
exploration expenditures over the next three years. An additional phase, which
is at the option of the Pennzoil/Forum Exploration group, would consist of three
 
                                       23
<PAGE>   25
 
additional years of exploration with a minimum expenditure of $5 million.
Seismic activity is currently in progress.
 
     In November 1995, Pennzoil announced that its Pennzoil Caspian Development
Corporation subsidiary had entered into a definitive exploration, development
and production sharing contract with SOCAR covering the Karabakh prospect in the
Caspian Sea offshore Azerbaijan. Participating in the project with Pennzoil
(30%) are units of LUKoil of Russia (7.5%), Agip of Italy (5%) and LUKAgip, a
subsidiary of LUKoil and Agip (50%). In addition, a commercial affiliate of
SOCAR has a 7.5% interest as a contractor party. The exploration, development
and production sharing agreement was ratified by the Azerbaijan Parliament on
February 13, 1996. The Karabakh prospect is located north of the
Azeri-Chirag-Gunashli deepwater unit and outside the Apsheron trend
approximately 50 miles offshore in approximately 600 feet of water. The work
commitment will include a seismic program and exploratory drilling over a period
of three years, which period may be extended an additional one-and-a-half years.
Should commercial hydrocarbons be discovered, the agreement will have a
development and production period of 25 years, which may be extended an
additional 5 years under certain conditions.
 
     Also in Azerbaijan, Pennzoil had completed work in 1994 on a comprehensive
gas gathering and compression system to capture, compress and transport to shore
approximately 150 MMcf per day of natural gas previously being vented from the
Gunashli field. As of December 31, 1995, over one-quarter of Pennzoil's
investment in the gas utilization project had been recovered through credit
toward Pennzoil's portion of bonus payments made to the government of Azerbaijan
with respect to the Karabakh prospect and the Azeri-Chirag-Gunashli fields,
direct payments from SOCAR during 1995 and other credits. Pennzoil's remaining
investment in the gas utilization project will be reimbursed through future
payments from SOCAR funded by bonus payments to be made by other participants in
the Karabakh prospect and in the Azeri-Chirag-Gunashli fields and additional
credits toward Pennzoil's future bonus payments with respect to the
Azeri-Chirag-Gunashli fields.
 
     Late in 1995, Pennzoil and a subsidiary of Agip of Italy were awarded the
West Feiran Block in the Gulf of Suez. Each company has a 50% interest. The West
Feiran Block, equivalent to 17 Gulf of Mexico blocks, lies in the east central
part of the Gulf of Suez and is surrounded by several giant oil fields.
Ratification by the Egyptian Parliament is expected in the first half of 1996.
 
     In June 1994, 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 consolidated statement of income. Reference is made to
Notes 3 and 10 of Notes to Consolidated Financial Statements 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. Under the production
sharing agreement, Pennzoil Qatar has committed to a seismic acquisition and
drilling program over the next four years. Drilling will begin in late 1996,
with four wells planned over the next several years.
 
     In September 1994, 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 deepwater portion of the Gunashli fields in the Caspian
Sea. The contract was ratified by the Azerbaijan Parliament in November 1994 and
was made effective in December 1994. Aggregate capital investment for all
members of 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. 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
 
                                       24
<PAGE>   26
 
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 September 1995, the consortium elected to pursue dual export routes for
transporting early oil production from the Caspian Sea, one north through an
existing pipeline system to a Russian port on the Black Sea, and the second west
through Azerbaijan and Georgia to the Black Sea. The western route will require
construction of 73 miles of pipeline to interconnect existing lines. All
necessary treaties and commercial agreements between governments and the western
companies for the northern route became effective in February 1996. Spending on
the early oil project will begin to accelerate as a result of these actions.
Pennzoil has recorded 14 million barrels of crude oil reserves relating to early
oil from this project.
 
     In November 1994, Pennzoil Egypt, 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 is
approximately the size of 44 Gulf of Mexico blocks. 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. Capital expenditures for the oil and gas segment in
1995 were $297.6 million compared to $399.5 million in 1994, excluding
expenditures related to Pennzoil's acquisition of Co-enerco, and $360.5 million
in 1993. Total capital expenditures for this segment in 1996 are budgeted at
$232.8 million. Reference is made to "-- Capital Resources and Liquidity" for
additional information.
 
MOTOR OIL & REFINED PRODUCTS
 
     Operating Results. Operating income in 1995 for this segment was $12.0
million compared with operating income of $41.8 million in 1994 and $90.0
million in 1993. Lower earnings in 1995 were primarily the result of charges
related to a fire at the Rouseville refinery, costs associated with the shutdown
of The Eureka Pipe Line Company ("Eureka"), which operated a crude oil gathering
system in West Virginia, costs associated with restructuring European marketing
operations and litigation settlement expenses. In addition, PPC incurred
expenses of $9.0 million in 1995 associated with Excel Paralubes, the 50-50
joint venture partnership between PPC and Conoco.
 
     Excluding nonrecurring charges, lower earnings in the manufacturing
division in 1995 resulted primarily from lower refining and specialty product
margins. Total processed volume at the refineries of 47,966 barrels per day in
1995 was 10,737 barrels per day lower than 1994 and 11,256 barrels per day lower
than 1993. Lower processed volumes resulted from the cessation of crude oil
processing at the refinery in Roosevelt, Utah as of September 30, 1994, coupled
with the effects of the fourth quarter 1995 fire at the Rouseville refinery and
a maintenance turnaround at the Atlas refinery in Shreveport, Louisiana.
 
     Lower earnings in the domestic marketing division, excluding nonrecurring
charges, were the result of lower GUMOUT(R) sales volumes and margins, higher
advertising, freight and other expenses, lower motor oil volumes and lower
revenues from other products. Domestic motor oil volumes were about 1% lower
than 1994 and about even with 1993 levels. Total international motor oil and
other lubricating product sales volumes, including those sold through licenses
and joint ventures, increased 7.6% when compared to 1994 and 46% when compared
to 1993.
 
     In October 1995, an explosion and fire occurred at PPC's Rouseville
refinery. Two PPC employees and three contractor employees were killed. Several
other injuries were reported. As of the date hereof, results of OSHA
investigations have not been released. The major damage identified was to the
tanks, piping and electrical lines in the area of the fire. Some portions of the
new wax plant project were damaged, and project completion has been delayed
until August 1996. A charge of $20.0 million was taken in the fourth quarter of
1995 for losses related to the fire. Reference is made to Note 8 of Notes to
Consolidated Financial Statements for additional information.
 
                                       25
<PAGE>   27
 
     In November 1995, PPC sold the assets of Eureka, a wholly owned subsidiary
that operated a crude oil gathering system in West Virginia. PPC recorded a
charge of $5.7 million for estimated costs associated with the disposal of the
facility.
 
     Business Activities. In June 1994, PPC and Conoco commenced work on a joint
venture project at Conoco's refinery in Lake Charles, Louisiana. Operating
through a 50-50 joint venture partnership called Excel Paralubes, the companies
are constructing a new, state-of-the-art lube oil hydrocracker facility
estimated to cost approximately $500 million, which is being funded with project
financing. The facility will produce approximately 18,000 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 late 1996, with operations commencing in early 1997. Conoco is
acting as construction manager and operator of the plant with support positions
staffed by both companies.
 
     In April 1995, PPC and the Polymers Division of Petrolite formed a 50-50
partnership called BARECO(R) Products to market a broad line of wax products to
domestic and international purchasers of paraffin, microcrystalline and related
synthetic waxes. Pennzoil transports partially refined feedstock from Utah to
its Rouseville refinery, which produces 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, are marketed through
the partnership. Pennzoil is investing more than $23 million in its Rouseville
refinery and its packaging plant in nearby Reno, Pennsylvania in connection with
this venture.
 
     In July 1995, PPC agreed to purchase a one-third ownership interest in a
manufacturing and marketing company located in Caracas, Venezuela. The company,
Aceites y Solventes Venezolanos Vassa S.A., has constructed and is commissioning
a facility in Cardon, Venezuela to manufacture white oils, solvents and
transformer oils for sale primarily in South America, Central America and the
Caribbean. Pennzoil's capital investment will be approximately $14.5 million, a
portion of which will be funded through nonrecourse project financing.
 
     In September 1995, PPC acquired the assets of the Viscosity Oil division of
Case for $33.6 million. Viscosity Oil is a leading supplier of premium-quality
lubricants to the North American off-road industry and it supplies lubricants to
substantially all the Case dealer network, with locations in all 50 states and
Canada. In addition, Viscosity Oil supplies virtually all of the factory-fill
lubricants for Case's North American manufacturing plants. As part of the
acquisition, a long-term supply agreement was entered into whereby Pennzoil will
supply the aftermarket lubricant products that Case will continue to sell to its
dealerships. The agreement also calls for Pennzoil to supply factory-fill
lubricants to Case. The acquisition was financed by a combination of cash on
hand and borrowings under Pennzoil's commercial paper facilities and short-term
variable-rate credit arrangements.
 
     In July 1995, PPC and a joint venture partner began work on a project to
build and operate a liquids terminal at the Port of Shreveport, Louisiana. The
opening of the Red River to navigation has provided the opportunity for PPC to
use less expensive waterborne freight for access to new feedstocks and markets
for the Atlas refinery and PPC's Shreveport packaging facility. Completion is
planned for October 1996.
 
     In December 1995, PPC purchased a 45% equity share in Isopetrol S.A., a
lubricants marketing and manufacturing company located in Lima, Peru. This
investment will allow PPC to increase its access to Peru and neighboring
markets. In addition, the agreement provides PPC an ownership interest in a
lubricants blending, packaging and grease plant located in Callao, Peru.
 
     Capital Expenditures. Capital expenditures for the motor oil and refined
products segments were $134.9 million in 1995, $40.4 million in 1994 and $71.5
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. 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. Capital
expenditures in 1995 included $52.3 million for the construction of a refinery
complex
 
                                       26
<PAGE>   28
 
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. Also included
was $19.2 million in expenditures for facilities at the Rouseville refinery to
enable production of additional waxes in connection with the previously
announced Petrolite joint venture. The 1996 capital budget of $214.3 million
includes funds of $129.2 million for completion of the Atlas upgrade project.
 
FRANCHISE OPERATIONS
 
     Operating Results. The franchise operations segment, operating through
Jiffy Lube, recorded operating income of $13.2 million during 1995, compared to
operating income of $2.8 million in 1994 and an operating loss of $17.6 million
in 1993. Operating income in 1995 continued to improve significantly due to
ongoing improvements in company center revenues and lower operating costs.
Operating results for 1995 include nonrecurring charges of $6.0 million for a
litigation settlement and $.3 million from severance charges associated with a
general and administrative cost reduction program. Operating results for 1994
included 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, 1995, Jiffy Lube
operated 477 company-owned service centers.
 
     Operating results for 1993 included a charge of $10.0 million for estimated
costs associated with centers that Jiffy Lube 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.
 
     Systemwide service center sales reported to Jiffy Lube for the year ended
December 31, 1995 increased $49.1 million, or approximately 8%, to $656.6
million, compared with the prior year, and increased $117.3 million, or
approximately 22%, compared with 1993. Average ticket prices increased to $34.71
for the year ended December 31, 1995, compared with $34.09 and $33.60 for the
years ended December 31, 1994 and 1993, respectively.
 
     Business Activities. In March 1995, Jiffy Lube and Sears agreed to open
fast-oil change units in Sears Auto Centers over the next three years. Under the
agreement, Jiffy Lube remodels, equips and operates service areas within the
Sears Auto Centers, while Sears continues to utilize the remaining bays for its
operations. As a first step, Sears and Jiffy Lube have agreed to set up
approximately 240 Jiffy Lube-owned and franchised centers and had 28 centers
open at the end of 1995.
 
     During the year ended December 31, 1995, Jiffy Lube acquired 52 centers
with estimated values of $30.2 million and real estate with estimated values of
$6.0 million in exchange for cash of $35.3 million, liabilities and debt assumed
of $1.3 million and four centers with a net book value of $.4 million. Also,
during the year ended December 31, 1995, nineteen centers were sold with an
estimated value of $1.9 million for $2.6 million in cash and $.3 million in
forgiveness of debt.
 
     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, 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.

     Capital Expenditures. Capital expenditures for the franchise operations
segment were $40.8 million in 1995, compared to $18.9 million and $21.7 million
in 1994 and 1993, respectively. Capital expenditures for 1996 are estimated to
be approximately $26.2 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 operate its international sulphur business.
Beginning in January 1995, the results of such operations are included in other
segment operating income. 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 DD&A of $50.2 million in
September 1994. As of December 31, 1995, Pennzoil has received $3.7 million in
installment payments.
 
     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. The average Green Markets Tampa Recovered Contract Price range for sulphur
had a mid-point of $57.00 per long ton in 1994 compared to a 1993 mid-point of
$64.00 per long ton. Intense competition in the domestic market 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. The lower level of sales volumes in 1994 and 1993
was primarily due to reduced market share resulting from lower priced imports
from Canada and increased recovered production domestically.
 
OTHER
 
     Other operating income in 1995 was $74.0 million, compared to $55.6 million
in 1994 and $253.7 million in 1993. The increase in other operating income in
1995 was primarily the result of a favorable resolution of a Texas franchise tax
issue, which resulted in Pennzoil's receiving a $23.2 million refund. In
addition, Pennzoil received approximately $1.5 million in interest associated
with the franchise tax refund. This increase in income was partially offset by
lower investment income as the result of having lower investable funds during
the year, primarily due to the October 1994 payment to the IRS associated with a
settlement related to a tax dispute. Reference is made to Note 8 of Notes to
Consolidated Financial Statements for additional information. Other operating
income for 1994 includes a $15.2 million charge to reflect an 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
$34.8 million for 1995, $33.4 million for 1994 and $60.2 million for 1993.

INTEREST CHARGES, NET
 
     During 1995, Pennzoil's interest charges, net of interest capitalized,
increased $12.0 million over 1994 levels, excluding interest charges of $294.3
million associated with the 1994 IRS settlement. Reference is made to Note 8 of
Notes to Consolidated Financial Statements for additional information. The
increase in interest charges net of capitalized interest, is due primarily to
slightly higher average borrowings at higher rates and lower capitalized
interest.

CAPITAL RESOURCES AND LIQUIDITY
 
     CASH FLOW. Pennzoil had cash and cash equivalents of $23.6 million and
$24.9 million at December 31, 1995 and 1994, respectively. Cash flow generated
from operations and proceeds from the sales of assets in 1995 totaled
approximately $639.4 million. These funds were used primarily for capital
expenditures ($473.4 million), for the acquisition of Viscosity Oil ($33.6
million) and for payment of cash dividends ($115.6 million).
 
     In October 1995, Pennzoil announced certain actions intended to increase
capital available for investment and growth opportunities. Pennzoil announced
that it was implementing a new program intended to reduce annual general and
administrative expenses, thereby resulting in future annual cost savings, and it
was reducing its fourth quarter dividend payment to $0.25 per share from the
$0.75 per share quarterly dividend that had been paid since 1988. At the reduced
quarterly dividend level, equivalent to an annualized dividend of $1.00 per
share, Pennzoil will conserve approximately $92 million annually which can be
used for investment and growth opportunities.
 
     PRICE RISK MANAGEMENT. Pennzoil has a price risk management program that
permits utilization of agreements and financial instruments (such as futures,
forward and option contracts and swaps and collars) to reduce the price risks
associated with fluctuations in crude oil and natural gas prices. The primary
purpose of the program, as it relates to 1996 crude oil and natural gas
production, is to help provide Pennzoil with sufficient cash from operations in
1996 to fund its capital spending program without increasing debt. As of
December 31, 1995, Pennzoil had entered into transactions that committed an
average of approximately 313,000 Mcf of natural gas per day for 1996 to be sold
at fixed prices (New York Mercantile Exchange
 
                                       29
<PAGE>   31
 
("NYMEX")-based) ranging from $1.73 to $2.67 per Mcf, with a weighted average
price of $1.86 per Mcf, and Pennzoil had entered into transactions that
committed an average of approximately 37,000 barrels of crude oil per day for
1996 to be sold at fixed prices (NYMEX-based) ranging from $16.75 per barrel to
$19.20 per barrel, with a weighted average price of $17.13 per barrel. As of
February 23, 1996, Pennzoil had entered into transactions that committed an
average of approximately 273,000 Mcf of natural gas per day for the remainder of
1996 to be sold at fixed prices (NYMEX-based) ranging from $1.80 to $2.86 per
Mcf, with the weighted average price of $1.80 per Mcf, and Pennzoil had entered
into transactions that committed an average of approximately 37,000 barrels of
crude oil per day for the remainder of 1996 to be sold at fixed prices
(NYMEX-based) ranging from $16.75 to $18.86 per barrel, with a weighted average
price of $17.07 per barrel. Pennzoil will constantly review and may alter its
hedged positions as conditions change. Pennzoil has not hedged crude oil or
natural gas prices beyond 1996.
 
     INVESTMENT IN CHEVRON CORPORATION. As of December 31, 1995, Pennzoil
beneficially owned 18,071,036 shares of Chevron common stock, 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.
Reference is made to Note 3 of Notes to Consolidated Financial Statements for
additional information. The current quarterly dividend rate on Chevron common
stock is $.50 per share. At the current dividend rate, Pennzoil receives $36.1
million annually in dividends on the 18,071,036 Chevron shares.
 
     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.
 
     CREDIT FACILITIES. In February 1995, Pennzoil's Board of Directors
increased the limit on the aggregate amount of commercial paper that Pennzoil
may issue under its commercial paper programs from $250.0 million to $500.0
million. Borrowings under Pennzoil's commercial paper facilities totaled $343.9
and $243.9 million at December 31, 1995 and December 31, 1994, respectively, and
are included in long-term debt and short-term notes payable, respectively in the
accompanying consolidated balance sheet. The average interest rates applicable
to outstanding commercial paper were 6.13% and 4.43% during 1995 and 1994,
respectively.
 
     Pennzoil's current revolving credit facility with a group of banks provides
for up to $600 million of unsecured revolving credit borrowings through May 28,
1996, with any outstanding borrowings on such date being converted into a term
credit facility terminating on May 30, 1997. 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. Outstanding borrowings under Pennzoil's
revolving credit facilities totaled $50.0 million and $205.0 million at December
31, 1995 and 1994, respectively. The average interest rate applicable to amounts
outstanding under Pennzoil's revolving credit facilities was 6.10% and 4.69%
during 1995 and 1994, respectively.
 
     Pennzoil Canada, an indirect wholly owned subsidiary, has a U.S. $185
million credit facility with a syndicate of banks, the borrowings under which
are guaranteed by Pennzoil. Pennzoil Canada also has an additional working
capital credit facility with a Canadian bank, the borrowings of which are
guaranteed by Pennzoil. These facilities provide for revolving credit borrowings
through May 28, 1996, with any outstanding borrowings on such date being
converted into term credit facilities terminating on May 30, 1997. Combined
borrowings under these facilities totaled U.S. $220.0 million and U.S. $195.0
million as of December 31, 1995 and December 31, 1994, respectively. The average
interest rate applicable to amounts outstanding under these facilities was 6.16%
and 5.27% during 1995 and 1994, respectively.
 
     Pennzoil has several short-term variable-rate credit arrangements with
certain banks. Pennzoil's Board of Directors has limited aggregate borrowings
under these credit arrangements to $200.0 million. Outstanding borrowings
totaled $125.0 million and $93.3 million at December 31, 1995 and 1994,
respectively, and are included in long-term debt and short-term notes payable,
respectively, in the accompanying consolidated balance sheet. The average
interest rates applicable to amounts outstanding under these arrangements were
5.95% and 4.31% during 1995 and 1994, respectively. None of the banks under
these credit arrangements has
 
                                       30
<PAGE>   32
 
any obligation to continue to extend credit after the maturities of outstanding
borrowings or to extend the maturities of any borrowings.
 
     As of December 31, 1995, borrowings under Pennzoil's commercial paper and
short-term variable-rate credit arrangements totaled $468.9 million, all of
which has been classified as long-term debt. Pennzoil does not intend or expect
to use working capital in 1996 for the settlement of these borrowings and
Pennzoil has the ability, by using existing revolving credit arrangements, to
refinance this short-term debt on a long-term basis. Similar borrowings totaling
$337.2 million were reflected as short-term debt as of December 31, 1994.
 
     Reference is made to Note 3 of Notes to Consolidated Financial Statements
for additional information regarding Pennzoil's credit facilities.
 
     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 1995 were $477.8
million, including $4.2 million of interest capitalized, an increase of $3.2
million from comparable 1994 capital expenditure levels. For 1995, capital
expenditures for motor oil and refined products include $0.6 million allocated
to property, plant and equipment related to Pennzoil's acquisition of Viscosity
Oil in September 1995.
 
     The table below summarizes the current 1996 capital budget by segment
compared with 1995 and 1994 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 1996 capital
expenditures from a combination of some, or all, of the following: cash flows
from operations, the sale of noncore assets, borrowings under its credit
facilities and commercial paper program, 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 $29 million in 1995 and $37 million in 1994.
Capital expenditures for environmental control facilities are currently expected
to be approximately $27 million in 1996. 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
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
 
                                       31
<PAGE>   33
 
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 remediation
costs that are subject to ongoing and evolving 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 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 is subject to the ongoing development of
remediation technologies. Pennzoil's assessment analysis takes into account the
condition of each site 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 Products Company
("Purolator") in 1992, 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 $15.7 million and $16.2 million recorded with respect to its
obligations under its indemnification agreement with Purolator as of December
31, 1995 and 1994, respectively. Reference is made to Note 8 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, 1995 and 1994, Pennzoil's consolidated balance
sheet included accrued liabilities for environmental remediation of $38.1
million and $44.9 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, $5.2 million
and $8.8 million are reflected in the consolidated balance sheet as current
liabilities as of December 31, 1995 and 1994, respectively, and $32.9 million
and $36.1 million are reflected as other liabilities as of December 31, 1995 and
1994, 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 EPA 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.

1995. 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, 1995 and 1994, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1995, in conformity with generally accepted accounting principles.
 
     As discussed in Note 1 to the Consolidated Financial Statements, effective
July 1, 1995, the Company changed its method of accounting for the impairment of
long-lived assets. Also, 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.

                       PENNZOIL COMPANY AND SUBSIDIARIES
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES --
 
  General Policies --
 
     The accompanying consolidated financial statements include all
majority-owned subsidiaries of Pennzoil Company ("Pennzoil"). All significant
intercompany accounts and transactions have been eliminated.
 
     Certain prior period items have been reclassified in the consolidated
financial statements in order to conform with the current year presentation.
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities, the
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  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, 1995 and 1994
was $46.914 and $43.270, respectively per share, based on the closing
transaction price for Chevron common stock reported on the NYSE on December 29,
1995 and December 30, 1994 of $52.375 and $44.625 per share, reduced by a $5.461
and $1.355 per share reserve, respectively, 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, 1995 and December 31, 1994, the net unrealized after-tax gain
included in shareholders' equity related to Pennzoil's investment in Chevron
common stock was $155.5 million and $112.7 million, respectively.

     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
Other Income, Net," which consists of the following:

                       PENNZOIL COMPANY AND SUBSIDIARIES
 
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
  Receivables --
 
     Current receivables include trade accounts and notes receivable and are net
of allowances for doubtful accounts of $9.6 million in 1995 and $10.5 million in
1994. Long-term receivables consist of notes receivable and are net of
allowances for doubtful accounts of $1.7 million in 1995 and $.9 million in
1994.
 
     At December 31, 1995 and 1994, current receivables included notes
receivable of $7.5 million and $10.7 million, respectively. Other assets
included long-term notes receivable of $40.5 million and $39.7 million at
December 31, 1995 and 1994, respectively.
 
  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 $111.7 million at December 31, 1995 and $122.2 million
at December 31, 1994. The current cost of LIFO inventories was approximately
$176.4 million and $182.5 million at December 31, 1995 and 1994, respectively.
 
  Oil and Gas Producing Activities --
 
     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 expense
("DD&A") 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 DD&A using
the unit-of-production method; actual costs are charged to accumulated
depreciation, depletion and amortization.
 
     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, 1995, Pennzoil's gas imbalance reflects a
net underproduced position of 2.7 billion cubic feet of gas. The company expects
to recover this imbalance from its co-owners through future production or
alternative arrangements.
 
     In April 1995, Pennzoil Gas Marketing, an indirect wholly owned Pennzoil
subsidiary, and BRING Gas Services Corp., a subsidiary of Brooklyn Union Gas
Co., formed PennUnion Energy Services, L.L.C. ("PennUnion"), a 50-50 gas
marketing joint venture. Pennzoil has committed over 90% of its natural gas
production from the continental United States through March 31, 1998 to be
marketed by PennUnion. During 1995, Pennzoil made natural gas sales to PennUnion
totaling approximately $192.3 million, of which $1.9 million was due Pennzoil at
December 31, 1995.
 
  Property, Plant and Equipment and Depreciation, Depletion and Amortization --
 
     Effective July 1, 1995, Pennzoil adopted the requirements of SFAS No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
Be Disposed Of," which is intended to establish more consistent accounting
standards for measuring the recoverability of long-lived assets. In certain
 
                                      F-10
<PAGE>   48
 
                       PENNZOIL COMPANY AND SUBSIDIARIES
 
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
instances, SFAS No. 121 specifies that the carrying values of assets be written
down to fair values, which, for Pennzoil, resulted in write-downs of proved oil
and gas properties that were not required under its prior impairment policy. In
determining whether an asset is impaired under the new standard, assets are
required to be grouped at the lowest level for which there are identifiable cash
flows that are largely independent of the cash flows of other groups of assets.
On this basis, certain proved oil and gas fields in North America were deemed to
be impaired because they were not expected to individually recover their entire
carrying value. The adoption of SFAS No. 121 resulted in Pennzoil recording a
pretax charge of $399.8 million for asset impairments, of which $378.9 million
was attributable to the impairment of Pennzoil's proved oil and gas properties.
The fair values used in calculating the write-down required for such properties
were determined by using the present value of expected future cash flows or
estimates of market value based on transactions for comparable properties, as
appropriate. Prior to the adoption of SFAS No. 121, Pennzoil periodically
reviewed the carrying amounts of proven properties and an impairment reserve was
provided as conditions warranted.
 
     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 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.
 
     The estimated costs of major maintenance, including turnarounds at
refineries, are accrued. Other expenditures for maintenance and repairs are
charged against income as incurred. Renewals and improvements are treated as
additions to property, plant and equipment, and items replaced are treated as
retirements.
 
  Price Risk Management and Other Hedging Activities --
 
     Pennzoil has a price risk management program that permits utilization of
agreements and financial instruments (such as futures, forward and option
contracts and swaps and collars) to reduce the price risks associated with
fluctuations in crude oil and natural gas prices. Gains and losses on these
instruments are recognized in income when the associated hedged commodities are
sold, and realized gains or losses related to anticipated production are treated
as deferred credits or charges and are included in other current liabilities or
other current assets.
 
     Deferred losses included in other current assets in the accompanying
balance sheet related to these hedging activities totaled $11.7 million at
December 31, 1995. Reference is made to Notes 4 and 5 for additional
information. There were no deferred gains or losses recorded on the company's
balance sheet as of December 31, 1994. Prior to the hedging of its 1996 oil and
natural gas production, Pennzoil's price risk management activities were not
material to its results of operations.
 
     Pennzoil also periodically hedges some of its monetary liabilities and
commitments denominated in foreign currencies. Gains and losses from foreign
currency hedges were recognized in "Other Income" and were not material in 1995
or 1994.
 
  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 $118.4 million at
December 31, 1995 and $88.2 million at December 31, 1994, net of accumulated
amortization of $26.3 million and $19.9 million, respectively. Goodwill is being
amortized on a straight-line basis over periods ranging from 20 to 40 years.
Amortization expense recorded during 1995 and 1994 was $8.5 million and $7.1
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 $188.9 million, $469.3
million and $183.6 million in 1995, 1994 and 1993, respectively. Interest
capitalized for 1995, 1994 and 1993 was $4.2 million, $9.0 million and $11.4
million, respectively. During 1995, Pennzoil received a cash tax refund, net of
payments of $107.2 million. Income taxes paid, net of refunds, during 1994 and
1993 were $395.1 million and $5.5 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.
 
     Changes in operating assets and liabilities, net of effects from the
purchases of equity interests in certain businesses acquired, consist of the
following:

(2) INCOME TAXES --
 
  Accounting for Income Taxes --
 
     Pennzoil accounts for income taxes under the provisions of SFAS No. 109,
"Accounting for Income Taxes." 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.
 
  Federal, State and Foreign --
 
     Federal, state and foreign income tax expense (benefit) for continuing
operations consists of the following:

     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 1994 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.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
     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, 1995, Pennzoil had a United States net operating loss
carryforward of approximately $6 million, which is available to reduce future
regular federal income taxes payable. Additionally, for purposes of determining
alternative minimum tax, an approximately $4 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 $75 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 were approximately $28 million as of December 31, 1995. A valuation
allowance of approximately $17 million has been established to offset the
portion of the deferred tax asset related to loss carryforwards expected to
expire before their utilization.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
     Pennzoil's current revolving credit facility with a group of banks provides
for up to $600 million of unsecured revolving credit borrowings through May 28,
1996, with any outstanding borrowings on such date being converted into a term
credit facility terminating on May 30, 1997. 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. Outstanding borrowings under Pennzoil's
revolving credit facilities totaled $50.0 million and $205.0 million at December
31, 1995 and 1994, respectively. The average interest rate applicable to amounts
outstanding under Pennzoil's revolving credit facilities was 6.10% and 4.69%
during 1995 and 1994, respectively.
 
     Pennzoil Canada, Inc. ("Pennzoil Canada"), an indirect wholly owned
subsidiary of Pennzoil, has a U.S. $185 million credit facility with a syndicate
of banks, the borrowings under which are guaranteed by Pennzoil. Pennzoil Canada
also has an additional working capital credit facility with a Canadian bank, the
borrowings of which are guaranteed by Pennzoil. These facilities provide for
revolving credit borrowings through May 28, 1996, with any outstanding
borrowings on such date being converted into term credit facilities terminating
on May 30, 1997. Combined borrowings under these facilities totaled U.S. $220.0
million and U.S. $195.0 million as of December 31, 1995 and December 31, 1994,
respectively. The average interest rate applicable to amounts outstanding under
these facilities was 6.16% and 5.27% during 1995 and 1994, respectively.
 
     In February 1995, Pennzoil's Board of Directors increased the limit on the
aggregate amount of commercial paper that Pennzoil may issue under its
commercial paper programs from $250.0 million to $500.0 million. Borrowings
under Pennzoil's commercial paper facilities totaled $343.9 million and $243.9
million at December 31, 1995 and 1994, respectively, and are included in
long-term debt and short-term notes payable, respectively, in the accompanying
consolidated balance sheet. The average interest rates applicable to outstanding
commercial paper were 6.13% and 4.43% during 1995 and 1994, respectively.
 
     Pennzoil has several short-term variable-rate credit arrangements with
certain banks. Pennzoil's Board of Directors has limited aggregate borrowings
under these credit arrangements to $200.0 million. Outstanding borrowings
totaled $125.0 million and $93.3 million at December 31, 1995 and 1994,
respectively, and are included in long-term debt and short-term notes payable,
respectively, in the accompanying consolidated balance sheet. The average
interest rates applicable to amounts outstanding under these arrangements were
5.95% and 4.31% during 1995 and 1994, 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.
 
     As of December 31, 1995, borrowings under Pennzoil's commercial paper and
short-term variable-rate credit arrangements totaled $468.9 million, all of
which has been classified as long-term debt. Pennzoil does not intend or expect
to use working capital in 1996 for the settlement of these borrowings and
Pennzoil has the ability, by using existing revolving credit arrangements, to
refinance this short-term debt on a long-term basis. Similar borrowings totaling
$337.2 million were reflected as short-term debt as of December 31, 1994.
 
     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, Pennzoil redeemed an aggregate of $388.6 million principal amount
of indebtedness. 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.
 
     At December 31, 1995, maturities of long-term debt for the years ending
December 31, 1996 to 2000 were $2.3 million, $747.8 million, $2.6 million,
$200.4 million and $.6 million, respectively. These maturities include $270.0
million and $468.9 million in 1997 related to the maturities of Pennzoil's
revolving credit facilities and borrowings under commercial paper and short-term
variable-rate credit arrangements, respectively. Such maturities also include
$5.8 million for the year ending December 31, 1997, 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.
 
     In connection with the issuance of debt by Excel Paralubes ("Excel"), a
partnership between Atlas Processing Company (an indirect wholly owned
subsidiary of Pennzoil) ("Atlas") and Conoco Inc., Pennzoil has guaranteed to
Excel and its lenders Atlas' obligations under Excel's project documents until
completion of the lubricating base oil facility being constructed by Excel in
Westlake, Louisiana. Prior to completion, these obligations include completing
the project or retiring Atlas' portion of Excel's debt in accordance with its
terms. The Pennzoil guarantee will terminate upon completion of the project and
will be replaced by a guarantee by Pennzoil Products Company ("PPC"), a wholly
owned subsidiary of Pennzoil. As of December 31, 1995, Atlas' portion of Excel's
outstanding debt was $126.0 million.
 
     Other 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 $34.6 million and $35.4 million have
been recognized in Pennzoil's consolidated balance sheet as of December 31, 1995
and 1994, 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, 1995,
the market value of the collateral represented approximately 165% of the
estimated credit risk.
 
     In connection with Pennzoil's disposition of Purolator Products Company
("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.
 
     Pennzoil has entered into forward exchange contracts to hedge some of its
foreign currency exposure. Pennzoil has also utilized financial agreements and
instruments (such as futures, forward and option contracts and swaps and
collars) to reduce the price risks associated with fluctuations in crude oil and
natural gas prices. With respect to natural gas, as of December 31, 1995,
Pennzoil had entered into transactions that committed an average of
approximately 313,000 thousand cubic feet ("Mcf") of natural gas per day for
1996 to be sold at fixed prices (New York Mercantile Exchange ("NYMEX")-based)
ranging from $1.73 to $2.67 per Mcf, with a weighted average price of $1.86 per
Mcf. With respect to crude oil, as of December 31, 1995, Pennzoil had entered
into transactions that committed an average of approximately 37,000 barrels of
crude oil per day for 1996 to be sold at fixed prices (NYMEX-based) ranging from
$16.75 per barrel to $19.20 per barrel, with a weighted average price of $17.13
per barrel. Pennzoil conducts its price risk management program with major
financial institutions and industry partners which the company believes present
a minimal credit risk. Pennzoil is exposed to potential market risk if its
physical markets for delivery do not substantially correlate with markets
designated as indices in the financial instruments used for price risk
management. To date, Pennzoil has not experienced significant credit or market
risk losses related to its price risk management program.
 
     Following are the amounts related to Pennzoil's financial guarantees and
contractual commitments to extend financial guarantees, credit and other
assistance and forward foreign currency exchange contracts as of December 31,
1995 and 1994.

     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 commitments 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 and fast lube 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,
1995. 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, 1995, receivables related to these group concentrations in
the oil and gas, motor oil and refined products and fast lube industries were
$86.6 million, $260.6 million, and $26.4 million, respectively, compared with
$128.1 million, $223.3 million and $31.8 million, respectively, at December 31,
1994.
 
(5) FAIR VALUE OF FINANCIAL INSTRUMENTS --
 
  Balance Sheet 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 balance sheet financial instruments.

</TABLE>
 
     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.
 
          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.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
  Off-Balance Sheet Financial Instruments --
 
     The estimated fair value of certain financial guarantees written and
commitments to extend financial guarantees was $7.8 million and $8.5 million as
of December 31, 1995 and December 31, 1994, respectively. 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.
 
     The estimated value of amounts owed by Pennzoil under its open commodity
price hedges was approximately $29.2 million as of December 31, 1995; such
amounts (to the extent realized) are expected to be substantially offset by
increases in the market prices of the underlying commodities. As of December 31,
1994, Pennzoil did not have any significant open commodity price hedges. The
estimated value of Pennzoil's open commodity price hedges is the amount that
Pennzoil would have to pay to terminate its hedge agreements, taking into
account the creditworthiness of the hedge counterparties.
 
     The estimated value of amounts owed by Pennzoil under its foreign currency
exchange contracts was $3.4 million as of December 31, 1995. Pennzoil did not
have any open foreign currency exchange contracts as of December 31, 1994. The
estimated value of Pennzoil's foreign currency exchange contracts represents the
original contract amount adjusted using the year-end closing spot exchange rate.
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.
 
     Net periodic pension cost for 1995, 1994 and 1993 included the following
components:

  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.
 
     Net periodic postretirement benefit cost for 1995, 1994 and 1993 included

     For measurement purposes, a 9% annual rate of increase in the per capita
cost of covered health care benefits was assumed for 1996; the rate was assumed
to decrease gradually to 5% 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, 1995 by $3.0
million and the aggregate of the service and interest cost components of net
periodic postretirement benefit cost for the year then ended by $0.3 million.
 
     The weighted-average discount rates used in determining the accumulated
postretirement benefit obligation as of December 31, 1995 and 1994 were 7.5% and
8.5%, 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 $10.7 million in 1995, $10.0 million in 1994 and $9.4 million in 1993.

  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 a 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, 1995. 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, 1995. 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, 1995, Pennzoil had 3,599,589 shares of common stock
reserved for issuance upon the grant and exercise of stock options and the grant
and maturity of conditional stock awards.
 
     At December 31, 1995, Pennzoil had nonqualified and incentive stock option
plans covering a total of 3,440,017 shares of Pennzoil common stock (compared to
2,601,982 shares at December 31, 1994), of which 852,277 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, 1995,
expiration dates for the outstanding options ranged from December 1997 to
December 2005 and the average exercise price per share was $58.75. 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 1995, there were 26,411 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, 1995, units covering 82,675 shares of Pennzoil
common stock were outstanding (compared to 79,778 shares at December 31, 1994).
In 1995, 12,633 shares of Pennzoil common stock were distributed to selected
employees upon maturity of awards granted under Pennzoil's conditional stock
award programs. During 1995, units covering 10,881 shares of Pennzoil's common
stock lapsed. These units had been granted in previous years under Pennzoil's
conditional stock award programs.
 
     In October 1995, the Financial Accounting Standards Board issued SFAS No.
123, "Accounting for Stock-Based Compensation," which established an elective
new standard on accounting for stock-based compensation. SFAS No. 123
establishes a fair value-based method of accounting for stock-based compensation
plans awarded after December 31, 1995 and encourages companies to adopt the
accounting method set forth in SFAS No. 123 in place of the existing accounting
method, which requires expense recognition only in situations where stock
compensation plans award intrinsic value to employees at the date of grant.
Companies that elect not to follow SFAS No. 123 for accounting purposes must
make annual pro forma disclosure of its effects. Adoption of the standard for
accounting purposes by Pennzoil would be required no later than the first
quarter of 1996, although earlier implementation is permitted. Pennzoil is
currently evaluating what effect, if any, SFAS No. 123 will have on its
financial position and results of operations.
 
(8) COMMITMENTS AND CONTINGENCIES --
 
  Tax Settlement --
 
     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

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
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
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") (subsequently renamed Pennzoil Exploration and
Production Company ("PEPCO")), which owned Gulf of Mexico, Gulf Coast, Permian
Basin and other domestic oil and gas producing properties. 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 DD&A 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 DD&A 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 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 these matters 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 in 1992, 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 $15.7 million and $16.2
million recorded with respect to its obligations under its indemnification
agreement with Purolator as of December 31, 1995 and 1994, respectively.
 
     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, 1995 and 1994, Pennzoil's consolidated balance
sheet included accrued liabilities for environmental remediation of $38.1
million and $44.9 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, $5.2 million
and $8.8 million are reflected on the consolidated balance sheet as current
liabilities as of December 31, 1995 and 1994, respectively, and $32.9 million
and $36.1 million are reflected as other liabilities as of December 31, 1995 and
1994, 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.
 
  Class Action --
 
     In April 1994, a lawsuit styled Lazy Oil, Inc. vs. Witco Corporation;
Quaker State Corporation; and Pennzoil Company, was filed in the United States
District Court for the Western District of Pennsylvania. Three other suits,
Andreassi vs. Witco Corporation; Quaker State Corporation; and Pennzoil Company
and Thomas A. Miller Oil vs. Witco Corporation; Quaker State Corporation; and
Pennzoil Company, and Wynnewood Drilling Associates v. Witco Corporation; Quaker
State Corporation; Quaker State Oil Refining Corporation; Pennzoil Company; and
Pennzoil Products Company were also filed in 1994, containing allegations
substantially identical to those in the Lazy Oil case. All four suits have been
consolidated for discovery and trial. The consolidated case, styled Lazy Oil
Co., John B. Andreassi and Thomas A. Miller Oil Co. on behalf of themselves and
others similarly situated vs. Witco Corporation; Quaker State Corporation;
Quaker State Oil Refining Corp.; Pennzoil Company and Pennzoil Products Company
is currently pending in the United States District Court for the Western
District of Pennsylvania, Erie Division. This class action suit brought by
purchasers of "Penn Grade crude" alleges that, from 1981 to 1995, the defendants
engaged in a combination and conspiracy in unreasonable restraint of trade in
violation of Section 1 of the Sherman Act, by allegedly acting to fix, lower,
maintain and stabilize the purchase price of "Penn Grade crude" sold by the
plaintiffs and the other class members to the defendants. The plaintiffs also
allege that the defendants have fraudulently concealed their alleged combination
and conspiracy. The plaintiffs seek injunctive relief, alleged damages sustained
by the plaintiffs and the class members and recovery of attorneys' fees and
costs. Plaintiffs' motion for class certification was not opposed by defendants,
and the Court has certified a class of plaintiffs consisting of all persons who
sold "Penn Grade crude" to any of the defendants between 1981 and June 30, 1995.
Quaker State and the plaintiffs have agreed on a proposed settlement of $4.4
million payable by Quaker State, which is pending before the court for approval.
Pennzoil is contesting the case vigorously. Pennzoil believes that the final
outcome of these matters will not have a material adverse effect on its
consolidated financial condition or results of operations.
 
  Ramco Dispute --
 
     In October 1995, PEPCO, Pennzoil International, Inc., Pennzoil Caspian
Corporation and Pennzoil Caspian Development Corporation filed an action, styled
Pennzoil Exploration and Production Company, et al. v. Ramco Energy Limited and
Ramco Hazar Energy Limited, in the United States District Court for the Southern
District of Texas, Houston Division, against Ramco Hazar Energy Limited,
formerly known as Ramco Energy Limited (collectively "Ramco"). The federal suit
seeks to compel Ramco to arbitrate certain disputes that have arisen between it
and the Pennzoil plaintiffs pursuant to the Federal Arbitration Act and the
Convention on the Recognition and Enforcement of Foreign Arbitral Awards. The
underlying dispute involves Ramco's asserted claim to an interest in the
Karabakh prospect, an oil and gas field located in the territorial waters of the
Azerbaijan Republic in the Caspian Sea and which Pennzoil Caspian Development
Corporation, the State Oil Company of the Azerbaijan Republic and other foreign
oil companies have agreed to explore and develop. After the filing of the
federal action, the Pennzoil plaintiffs filed an Original Petition for
Declaration Relief in the 281st Judicial District Court of Harris County, Texas.
The state suit, styled Pennzoil Exploration and Production Company, et al. v.
Ramco Energy Limited and Ramco Hazar Energy Limited, which is expressly
conditioned upon a determination in the federal suit that the disputes between
the Pennzoil plaintiffs and Ramco are not subject to arbitration, seeks a
declaration that the Pennzoil plaintiffs have not breached any agreements with
Ramco, and do not owe and/or have not breached any fiduciary or other legal duty
to Ramco including, without limitation, a duty of good faith and fair dealing.
In November 1995, Ramco

asserted a counterclaim in the state court action, asserting breach of contract
and breach of fiduciary duties. The counterclaim seeks a declaratory judgment
granting Ramco a participation interest in the Karabakh prospect, compensatory
damages, exemplary damages, attorneys fees, costs of court and other unspecified
relief. In January 1996, the judge in the federal suit granted in part the
Pennzoil plaintiffs' motion to compel arbitration and ordered arbitration to be
held in Stockholm, Sweden. The Pennzoil plaintiffs and the Ramco defendants have
each asked the judge to reconsider portions of his order. The court has not
ruled upon the motions for reconsideration. Pennzoil believes that the final
outcome of these matters will not have a material adverse effect on its
consolidated financial condition or results of operations.
 
  Rouseville Refinery Fire --
 
     In October 1995, an explosion and fire occurred at PPC's Rouseville
refinery. Two PPC employees and three contractor employees were killed. Several
other injuries were reported. Four lawsuits have been filed against PPC,
alleging that PPC's negligence caused serious injury or death. All suits seek
unspecified damages in excess of $25,000. The suits are pending in Allegheny
County, Pennsylvania state court. Pennzoil believes that the final outcome of
these matters will not have a material adverse effect on its consolidated
financial condition or results of operations.
 
  Other --
 
     Pennzoil and its subsidiaries are involved in various other claims,
lawsuits and other proceedings relating to a wide variety of matters. While
uncertainties are inherent in the final outcome of such matters and it is
presently impossible to determine the actual costs that ultimately may be
incurred, management currently believes that the resolution of such
uncertainties and the incurrence of such costs should not have a material
adverse effect on Pennzoil's consolidated 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 $70.0 million, $63.5 million and $59.6 million for 1995,
1994 and 1993, respectively. Non-current capital lease obligations are
classified as other liabilities in the accompanying consolidated balance sheet.

  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 Viscosity Oil --
 
     In September 1995, PPC acquired the assets of the Viscosity Oil division
("Viscosity Oil") of Case Corporation for $33.6 million. The acquisition was
financed by a combination of cash on hand and borrowings under Pennzoil's
commercial paper facilities and short-term variable-rate credit arrangements.
The acquisition was accounted for using the purchase method of accounting, and
the results of operations of Viscosity Oil subsequent to September 1995 have
been included in Pennzoil's consolidated statement of income.
 
  Acquisition of Co-enerco Resources Ltd. --
 
     In June 1994, Pennzoil Canada, an indirect wholly owned subsidiary of
Pennzoil, acquired Co-enerco Resources Ltd. ("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 consolidated statement of income.
 
  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 operate its 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. As of December
31, 1995, Pennzoil has received $3.7 million in installment payments.

 (1) Total costs incurred during 1995, 1994 and 1993 include $13 million, $50
     million and $114 million, respectively, related to Pennzoil's Azerbaijan
     activities. Costs incurred (reimbursed) for unproved property acquisition
     during 1995, 1994 and 1993 include approximately ($36) million, $48 million
     and $98 million, respectively, related to the gas utilization project in
     Azerbaijan. 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 1995 were $303 million.
 
 (2) Costs incurred for property acquisitions in 1994 include $231 million
     attributable to the acquisition of Co-enerco. Reference is made to Note 10
     of Notes to Consolidated Financial Statements for additional information.

  Results of Operations From Oil and Gas Producing Activities
 
     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 1995, 1994 and 1993 includes
    approximately $4 million, $9 million and $7 million, respectively, related
    to Pennzoil's Azerbaijan activities.
 
(2) Effective July 1, 1995, Pennzoil adopted the requirements of SFAS No. 121,
    "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
    Assets to Be Disposed Of." As a result, Pennzoil recorded a pretax charge of
    $378.9 million as of July 1, 1995, to reflect the impairment of long-lived
    oil and gas assets. Reference is made to "Management's Discussion and
    Analysis of Financial Condition and Results of Operations -- Oil and Gas"
    and Note 1 of Notes to Consolidated Financial Statements for additional
    information. 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 (subsequently
    renamed PEPCO) 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 DD&A 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 Note 8 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.

                                  (As Amended)

                                   ARTICLE I.
                            MEETINGS OF SHAREHOLDERS

        SECTION 1. The annual meeting of the shareholders of this Corporation
shall be held on the second Thursday of May in each year, at ten o'clock
A.M., and on any subsequent day or days to which such meeting may be adjourned,
for the purposes of electing directors and of transacting such other business
as may properly come before the meeting.  The Board of Directors shall
designate the place for the holding of such meeting, and at least ten days'
notice shall be given to the shareholders of the place so fixed.  If the day
designated herein is a legal holiday, the annual meeting shall be held
on the first succeeding day which is not a legal holiday.  If for any reason
the annual meeting shall not be held on the day designated herein, the Board of
Directors shall cause the annual meeting to be held as soon thereafter as may
be convenient.

        SECTION 2.  Special meetings of the shareholders may be called at any
time by the Board of Directors, the Chairman of the Board, the Executive
Committee, the Chairman of the Executive Committee or the President.  Upon
written request of any person or persons who have duly called a special
meeting, it shall be the duty of the Secretary of the Corporation to fix the
date of the meeting to be held not less than ten nor more than sixty days after
the receipt of the request and to give due notice thereof.  If the Secretary
shall neglect or refuse to fix the date of the meeting and give notice thereof,
the person or persons calling the meeting may do so.

        SECTION 3.  Every special meeting of the shareholders shall be held at
such place within or without the State of Delaware as the Board of Directors
may designate, or, in the absence of such designation, at the registered office
of the Corporation in the State of Delaware.

        SECTION 4.  Written notice of every meeting of the shareholders shall
be given by the Secretary of the Corporation to each shareholder of record
entitled to vote at the meeting, by placing such notice in the mail at least
ten days, but not more than sixty days, prior to the day named for the meeting
addressed to each shareholder at his address appearing on the books of the
Corporation or supplied by him to the Corporation for the purpose of notice.

        SECTION 5.  The Board of Directors may fix a date, not less than ten
nor more than sixty days preceding the date of any meeting of shareholders, as
a record date for the determination of shareholders entitled to notice of, or
to vote at, any such meeting.  The Board of Directors shall not close the books
of the Corporation against transfers of shares during the whole or any part of
such period.

        SECTION 6.  The notice of every meeting of the shareholders may be
accompanied by a form of proxy approved by the Board of Directors in favor of
such person or persons as the Board of Directors may select.

        SECTION 7.  A majority of the outstanding shares of stock of the
Corporation entitled to vote, present in person or represented by proxy, shall
constitute a quorum at any meeting of the shareholders, and the shareholders
present at any duly convened meeting may continue to do business until
adjournment notwithstanding any withdrawal from the meeting of holders of
shares counted in determining the existence of a quorum.  Directors shall be
elected by a plurality of the votes cast in the election.  For all matters as
to which no other voting requirement is specified by the General Corporation
Law of the State of Delaware (the "General Corporation Law"), the Restated
Certificate of Incorporation of the Corporation, as amended (the "Certificate
of Incorporation") or these By-laws, the affirmative vote required for
shareholder action shall be that of a majority of the shares present in person
or represented by proxy at the meeting (as counted for purposes of determining
the existence of a quorum at the meeting).  In the case of a matter submitted
for a vote of the shareholders as to which a shareholder approval requirement
is applicable under the shareholder approval policy of the New York Stock
Exchange, the requirements of Rule 16b-3 under the Securities Exchange Act of
1934 or any provision of the Internal Revenue Code, in each case for which no
higher voting requirement is specified by the General Corporation Law, the
Certificate of Incorporation or these By-laws, the vote required for approval
shall be the requisite vote specified in such shareholder approval policy, Rule
16b-3 or Internal Revenue Code provision, as the case may be (or the highest
such requirement if more than one is applicable).  For the approval of the
appointment of independent public accountants (if submitted for a vote of the
shareholders), the vote required for approval shall be a majority of the votes
cast on the matter.

        SECTION 8.  Any meeting of the shareholders may be adjourned from time
to time, without notice other than by announcement at the meeting at which such
adjournment is taken, and at any such adjourned meeting at which a 


<PAGE>   2
quorum shall be present any action may be taken that could have been taken
at the meeting originally called; provided that if the adjournment is for more
than thirty days, or if after the adjournment a new record date is fixed for
the adjourned meeting, a notice of the adjourned meeting shall be given to each
shareholder of record entitled to vote at the adjourned meeting.

        SECTION 9.  Subject to such rights of the holders of Preferred Stock or
Preference Common Stock or any series thereof as shall be prescribed in the
Certificate of Incorporation or in the resolutions of the Board of Directors
providing for the issuance of any such series, only persons who are nominated
in accordance with the procedures set forth in this Section 9 shall be eligible
for election as, and to serve as, directors.  Nominations of persons for
election to the Board of Directors may be made at a meeting of the shareholders
at which Directors are to be elected (a) by or at the direction of the Board of
Directors or (b) by any shareholder of the Corporation entitled to vote at such
meeting in the election of directors who complies with the requirements of this
Section 9.  Such nominations, other than those made by or at the direction of
the Board of Directors, shall be preceded by timely advance notice in writing
to the Secretary of the Corporation.  To be timely, a shareholder's notice
shall be delivered to, or mailed and received at, the principal executive
offices of the Corporation not less than 60 days prior to the scheduled meeting
date, regardless of any postponements, deferrals or adjournments of the meeting
to a later date; provided, however, that if the scheduled meeting date differs
from the annual meeting date prescribed by the By-laws as in effect on the date
of the next preceding annual meeting of shareholders and if less than 70 days'
notice or prior public disclosure of the scheduled meeting date is given or
made, notice by the shareholder, to be timely, must be so delivered or received
not later than the close of business on the tenth day following the earlier of
the day on which the notice of such meeting was mailed to shareholders or the
day on which such public disclosure was made.  A shareholder's notice to the
Secretary shall set forth (x) as to each person whom the shareholder proposes
to nominate for election or re-election as a director, (i) the name, age,
business address and residence address of such person, (ii) the principal
occupation or employment of such person, (iii) the number of shares of each
class of capital stock of the Corporation beneficially owned by such person and
(iv) the written consent of such person to having such person's name placed in
nomination at the meeting and to serve as a director if elected, and (y) as to
the shareholder giving the notice, (i) the name and address, as they appear on
the Corporation's books, of such shareholder and (ii) the number of shares of
each class of voting stock of the Corporation which are then beneficially owned
by such shareholder.  The presiding officer of the meeting of shareholders
shall determine whether the requirements of this Section 9 have been met with
respect to any nomination or intended nomination.  If the presiding officer
determines that any nomination was not made in accordance with the requirements
of this Section 9, he shall so declare at the meeting and the defective
nomination shall be disregarded.

        SECTION 10.  At an annual meeting of shareholders, only such business
shall be conducted, and only such proposals shall be acted upon, as shall have
been brought before the annual meeting (a) by or at the direction of the Board
of Directors or (b) by any shareholder of the Corporation who complies with the
requirements of this Section 10 and as shall otherwise be proper subjects for
shareholder action and shall be properly introduced at the meeting.  For a
proposal to be properly brought before an annual meeting by a shareholder, the
shareholder must have given timely advance notice thereof in writing to the
Secretary of the Corporation.  To be timely, a shareholder's notice must be
delivered to, or mailed and received at, the principal executive offices of the
Corporation not less than 60 days prior to the scheduled meeting date,
regardless of any postponements, deferrals or adjournments of that meeting to a
later date; provided, however, that if the scheduled meeting date differs from
the meeting date prescribed by the By-laws as in effect on the date of the next
preceding annual meeting of shareholders and if less than 70 days' notice or
prior public disclosure of the scheduled meeting date is given or made, notice
by the shareholder, to be timely, must be so delivered or received not later
than the close of business on the tenth day following the earlier of the day on
which the notice of such meeting was mailed to shareholders or the day on which
such public disclosure was made.  A shareholder's notice to the Secretary shall
set forth as to each matter the shareholder proposes to bring before the annual
meeting (a) a description of the proposal desired to be brought before the
annual meeting and the reasons for conducting such business at the annual
meeting, (b) the name and address, as they appear on the Corporation's books,
of the shareholder proposing such business and any other shareholders known by
such shareholder to be supporting such proposal, (c) the class and number of
shares of the Corporation's stock which are beneficially owned by the
shareholder on the date of such notice and (d) any financial interest of the
shareholder in such proposal.

        The presiding officer of the annual meeting shall determine whether the
requirements of this Section 10 have been met with respect to any shareholder
proposal.  If the presiding officer determines that a shareholder proposal was
not made in accordance with the terms of this Section 10, he shall so declare
at the meeting and any such proposal shall not be acted upon at the meeting.

        At a special meeting of shareholders, only such business shall be acted

                             BOARD OF DIRECTORS

        SECTION 1.  The business, affairs and property of the Corporation shall
be managed by a board of ten directors divided into three classes as provided
in the Certificate of Incorporation of the Corporation. Each director shall
hold office for the full term to which he shall have been elected and until his
successor is duly elected and shall qualify, or until his earlier death,
resignation or removal.  A director need not be a resident of the State of
Delaware or a shareholder of the Corporation.

        SECTION 2.  Except as provided in the Certificate of Incorporation of
the Corporation, newly created directorships resulting from any increase in the
number of directors and any vacancies on the Board of Directors resulting from
death, resignation, disqualification, removal or other cause shall be filled by
the affirmative vote of a majority of the remaining directors then in office,
even though less than a quorum of the Board of Directors.  Any director elected
in accordance with the preceding sentence shall hold office for the remainder
of the full term of the class of directors in which the new directorship was
created or the vacancy occurred and until such director's successor shall have
been elected and qualified.  No decrease in the number of directors
constituting the Board of Directors shall shorten the term of any incumbent
director.

        SECTION 3.  No director of the Corporation shall be removed from his
office as a director by vote or other action of shareholders or otherwise
except for cause.

        SECTION 4.  Regular meetings of the Board of Directors shall be held at
such place or places within or without the State of Delaware, at such hour and
on such day as may be fixed by resolution of the Board of Directors, without
further notice of such meetings.  The time or place of holding regular meetings
of the Board of Directors may be changed by the Chairman of the Board or the
President by giving written notice thereof as provided in Section 6 of this
Article II.

        SECTION 5.  Special meetings of the Board of Directors shall be held,
whenever called by the Chairman of the Board, the Chairman of the Executive
Committee, the President, by four directors or by resolution adopted by the
Board of Directors, at such place or places within or without the State of
Delaware as may be stated in the notice of the meeting.

        SECTION 6.  Written notice of the time and place of, and general nature
of the business to be transacted at, all special meetings of the Board of
Directors, and written notice of any change in the time or place of holding the
regular meetings of the Board of Directors, shall be given to each director
personally or by mail or by telegraph, telecopier or similar communication at
least one day before the day of the meeting; provided, however, that notice of
any meeting need not be given to any director if waived by him in writing, or
if he shall be present at such meeting.

        SECTION 7.  A majority of the directors in office shall constitute a
quorum of the Board of Directors for the transaction of business; but a lesser
number may adjourn from day to day until a quorum is present.  Except as
otherwise provided by law or in these By-laws, all questions shall be decided
by the vote of a majority of the directors present.

        SECTION 8.  Any action which may be taken at a meeting of the directors
or members of the Executive Committee may be taken without a meeting if consent
in writing setting forth the action so taken shall be signed by all of the
directors or members of the Executive Committee as the case may be and shall be
filed with the Secretary of the Corporation.

        SECTION 9.  The Board of Directors may designate one or more of its
number to be Vice Chairman of the Board, Chairman of the Executive Committee,
and Chairman of any other committees of the Board and to hold such other
positions on the Board as the Board of Directors may designate.

                                  ARTICLE III.
                              EXECUTIVE COMMITTEE

  The Board of Directors may, by resolution adopted by a majority of the whole
Board, designate two or more of its number to constitute an Executive Committee
which committee, during intervals between meetings of the Board, shall have and
exercise the authority of the Board of Directors in the management of the
business of the Corporation to the extent permitted by law.

                                  OFFICERS

        SECTION 1.  The officers of the Corporation shall consist of a Chairman
of the Board, President, Secretary, Treasurer and such Executive, Group, Senior
or other Vice Presidents, and other officers as may be elected or appointed by
the Board of Directors.  Any number of offices may be held by the same person. 
All officers shall hold office until their successors are elected or appointed,
except that the Board of Directors may remove any officer at any time at its
discretion.

        SECTION 2.  The officers of the Corporation shall have such powers and
duties as generally pertain to their offices, except as modified herein or by
the Board of Directors, as well as such powers and duties as from time to time
may be conferred by the Board of Directors.  The Chairman of the Board shall
have such duties as may be assigned to him by the Board of Directors and shall
preside at meetings of the Board and at meetings of the stockholders.  The
President shall be the chief executive officer of the Corporation and shall
have general supervision over the business, affairs, and property of the
Corporation.

                                 ARTICLE V.
                                    SEAL

        The seal of the Corporation shall be in such form as the Board of
Directors shall prescribe.

                                 ARTICLE VI.
                            CERTIFICATES OF STOCK

        The shares of stock of the Corporation shall be represented by
certificates of stock, signed by the President or such Vice President or other
officer designated by the Board of Directors, countersigned by the Treasurer or
the Secretary; and such signature of the President, Vice President, or other
officer, such countersignature of the Treasurer or Secretary, and such seal, or
any of them, may be executed in facsimile, engraved or printed.  In case any
officer who has signed or whose facsimile signature has been placed upon any
share certificate shall have ceased to be such officer because of death,
resignation or otherwise before the certificate is issued, it may be issued by
the Corporation with the same effect as if the officer had not ceased to be
such at the date of its issue.  Said certificates of stock shall be in such
form as the Board of Directors may from time to time prescribe.

                                ARTICLE VII.
                               INDEMNIFICATION

        SECTION 1.  The Corporation shall indemnify, and advance Expenses (as
this and all other capitalized words are defined in Section 12) to, Indemnitee
to the fullest extent permitted by applicable law in effect on July 24, 1986,
and to such greater extent as applicable law may thereafter permit.  The rights
of Indemnitee provided under the preceding sentence shall include, but not be
limited to, the right to be indemnified to the fullest extent permitted by 
Section 145(b) of the D.G.C.L. in Proceedings by or in the right of the 
Corporation and to the fullest extent permitted by Section 145(a) of the 
D.G.C.L. in all other Proceedings.

        SECTION 2.  If Indemnitee is, by reason of his Corporate Status, a
witness in or a party to and is successful, on the merits or otherwise, in any
Proceeding, he shall be indemnified against all Expenses actually and
reasonably incurred by him or on his behalf in connection therewith.  If
Indemnitee is not wholly successful in such Proceeding but is successful, on
the merits or otherwise, as to any Matter in such Proceeding, the Corporation
shall indemnify Indemnitee against all Expenses actually and reasonably
incurred by him or on his behalf relating to each Matter.  The termination of
any Matter in such a Proceeding by dismissal, with or without prejudice, shall
be deemed to be a successful result as to such Matter.

        SECTION 3.  Indemnitee shall be advanced Expenses within 10 days after
requesting them to the fullest extent permitted by Section 145(e) of 
the D.G.C.L.

        SECTION 4.  To obtain indemnification Indemnitee shall submit to the
Corporation a written request with such information as is reasonably available
to Indemnitee.  The Secretary of the Corporation shall promptly advise the
Board of Directors of such request.

        SECTION 5.  If there has been no Change of Control at the time the
request for indemnification is sent, Indemnitee's entitlement to
indemnification shall be determined in accordance with Section 145(d) of 
the D.G.C.L.  If entitlement to indemnification is to be determined by 
Independent Counsel, the Corporation shall furnish notice to Indemnitee 
within 10 days after receipt of the request for indemnification,
specifying the identity and address of



                                      4
<PAGE>   5
Independent Counsel.  The Indemnitee may, within 14 days after receipt of such
written notice of selection, deliver to the Corporation a written objection to
such selection.  Such objection may be asserted only on the ground that the
Independent Counsel so selected does not meet the requirements of Independent
Counsel and the objection shall set forth with particularity the factual basis
of such assertion.  If there is an objection to the selection of Independent
Counsel, either the Corporation or Indemnitee may petition the Court of
Chancery of the State of Delaware or any other court of competent jurisdiction
for a determination that the objection is without a reasonable basis and/or for
the appointment of Independent Counsel selected by the Court.

        SECTION 6.  If there has been a Change of Control at the time the
request for indemnification is sent, Indemnitee's entitlement to indemnification
shall be determined in a written opinion by Independent Counsel selected by
Indemnitee. Indemnitee shall give the Corporation written notice advising of the
identity and address of the Independent Counsel so selected.  The Corporation
may, within 7 days after receipt of such written notice of selection, deliver to
the Indemnitee a written objection to such selection. Indemnitee may, within 5
days after the receipt of such objection from the Corporation, submit the name
of another Independent Counsel and the Corporation may, within 7 days after
receipt of such written notice of selection, deliver to the Indemnitee a written
objection to such selection.  Any objection is subject to the limitations in
Section 5.  Indemnitee may petition the Court of Chancery of the State of
Delaware or any other Court of competent jurisdiction for a determination that
the Corporation's objection to the first and/or second selection of Independent
Counsel is without a reasonable basis and/or for the appointment as Independent
Counsel of a person selected by the Court.

        SECTION 7.  If a Change of Control shall have occurred before the
request for indemnification is sent by Indemnitee, Indemnitee shall be presumed
(except as otherwise expressly provided in this Article) to be entitled to
indemnification upon submission of a request for indemnification in accordance
with Section 4 of this Article, and thereafter the Corporation shall have the
burden of proof to overcome the presumption in reaching a determination
contrary to the presumption.  The presumption shall be used by Independent
Counsel as a basis for a determination of entitlement to indemnification unless
the Corporation provides information sufficient to overcome such presumption by
clear and convincing evidence or the investigation, review and analysis of
Independent Counsel convinces him by clear and convincing evidence that the
presumption should not apply.

        Except in the event that the determination of entitlement to
indemnification is to be made by Independent Counsel, if the person or persons
empowered under Section 5 or 6 of this Article to determine entitlement to
indemnification shall not have made and furnished to Indemnitee in writing a
determination within 60 days after receipt by the Corporation of the request
therefor, the requisite determination of entitlement to indemnification shall
be deemed to have been made and Indemnitee shall be entitled to such
indemnification unless Indemnitee knowingly misrepresented a material fact in
connection with the request for indemnification or such indemnification is
prohibited by law.  The termination of any Proceeding or of any Matter therein,
by judgment, order, settlement or conviction, or upon a plea of nolo contendere
or its equivalent, shall not (except as otherwise expressly provided in this
Article) of itself adversely affect the right of Indemnitee to indemnification
or create a presumption that Indemnitee did not act in good faith and in a
manner which he reasonably believed to be in or not opposed to the best
interests of the Corporation, or with respect to any criminal Proceeding, that
Indemnitee had reasonable cause to believe that his conduct was unlawful.

        SECTION 8.  The Corporation shall pay any and all reasonable fees and
expenses of Independent Counsel incurred acting pursuant to this Article and in
any proceeding to which it is a party or witness in respect of its
investigation and written report and shall pay all reasonable fees and expenses
incident to the procedures in which such Independent Counsel was selected or
appointed.  No Independent Counsel may serve if a timely objection has been
made to his selection until a Court has determined that such objection is
without a reasonable basis.

        SECTION 9.  In the event that (i) a determination is made pursuant to
Section 5 or 6 that Indemnitee is not entitled to indemnification under this
Article, (ii) advancement of Expenses is not timely made pursuant to Section 3
of this Article, (iii) Independent Counsel has not made and delivered a written
opinion determining the request for indemnification (a) within 90 days after
being appointed by the Court, or (b) within 90 days after objections to his
selection have been overruled by the Court, or (c) within 90 days after the
time for the Corporation or Indemnitee to object to his selection, or (iv)
payment of indemnification is not made within 5 days after a determination of
entitlement to indemnification has been made or deemed to have been made
pursuant to Section 5, 6 or 7 of this Article, Indemnitee shall be entitled to
an adjudication in an appropriate court of the State of Delaware, or in any
other court of competent jurisdiction, of his entitlement to such
indemnification or advancement of Expenses.  In the event that a determination
shall have been made that Indemnitee is not entitled to indemnification, any
judicial proceeding or arbitration commenced pursuant to this Section shall be
conducted in all respects as a de novo trial on the merits and Indemnitee shall
not be prejudiced by reason of that adverse determination.  If a Change of
Control shall have occurred, in any judicial proceeding commenced pursuant to
this Section, the Corporation shall have the burden of proving that Indemnitee
is not entitled to indemnification or advancement of Expenses, as the


                                      5
<PAGE>   6
case may be.  If a determination shall have been made or deemed to have been
made that Indemnitee is entitled to indemnification, the Corporation shall be
bound by such determination in any judicial proceeding commenced pursuant to
this Section 9, or otherwise, unless Indemnitee knowingly misrepresented a
material fact in connection with the request for indemnification, or such
indemnification is prohibited by law.

        The Corporation shall be precluded from asserting in any judicial
proceeding commenced pursuant to this Section 9 that the procedures and
presumptions of this Article are not valid, binding and enforceable and shall
stipulate in any such court that the Corporation is bound by all provisions of
this Article.  In the event that Indemnitee, pursuant to this Section 9, seeks
a judicial adjudication to enforce his rights under, or to recover damages for
breach of, this Article, Indemnitee shall be entitled to recover from the
Corporation, and shall be indemnified by the Corporation against, any and all
Expenses actually and reasonably incurred by him in such judicial adjudication,
but only if he prevails therein.  If it shall be determined in such judicial
adjudication that Indemnitee is entitled to receive part but not all of the
indemnification or advancement of Expenses sought, the Expenses incurred by
Indemnitee in connection with such judicial adjudication or arbitration shall
be appropriately prorated.

        SECTION 10.  The rights of indemnification and to receive advancement
of Expenses as provided by this Article shall not be deemed exclusive of any
other rights to which Indemnitee may at any time be entitled under applicable
law, the Certificate of Incorporation, the By-laws, any agreement, a vote of
stockholders or a resolution of directors, or otherwise.  No amendment,
alteration or repeal of this Article or any provision thereof shall be
effective as to any Indemnitee for acts, events and circumstances that
occurred, in whole or in part, before such amendment, alteration or repeal. The
provisions of this Article shall continue as to an Indemnitee whose Corporate
Status has ceased and shall inure to the benefit of his heirs, executors and
administrators.

        SECTION 11.  If any provision or provisions of this Article shall be
held to be invalid, illegal or unenforceable for any reason whatsoever, the
validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby; and, to the fullest extent possible,
the provisions of this Article shall be construed so as to give effect to the
intent manifested by the provision held invalid, illegal or unenforceable.

        SECTION 12.  For purposes of this Article:

                "Change of Control" means a change in control of the 
Corporation after July 24, 1986 in any one of the following circumstances (1)
there shall have occurred an event required to be reported in response to
Item 6(e) of Schedule 14A of Regulation 14A (or in response to any similar
item on any similar schedule or form) promulgated under the Securities Exchange
Act of 1934 (the "Act"), whether or not the Corporation is then subject to such
reporting requirement; (2) any "person" (as such term is used in Section 13(d)
and 14(d) of the Act) shall have become the "beneficial owner" (as defined in
Rule 13d-3 under the Act), directly or indirectly, of securities of the
Corporation representing 40% or more of the combined voting power of the
Corporation's then outstanding voting securities without prior approval of at
least two-thirds of the members of the Board of Directors in office immediately
prior to such person attaining such percentage interest; (3) the Corporation is
a party to a merger, consolidation, sale of assets or other reorganization, or
a proxy contest, as a consequence of which members of the Board of Directors in
office immediately prior to such transaction or event constitute less than a
majority of the Board of Directors thereafter; (4) during any period of two
consecutive years, individuals who at the beginning of such period constituted
the Board of Directors (including for this purpose any new director whose
election or nomination for election by the Corporation's stockholders was
approved by a vote of at least two-thirds of the directors then still in office
who were directors at the beginning of such period) cease for any reason to
constitute at least a majority of the Board of Directors.

                "Corporate Status" describes the status of a person who (a) is
or was a director, officer or employee of the Corporation, or is or was
serving at the request of the Corporation as a director, officer or employee of
another corporation, partnership, joint venture, trust or other enterprise, in
each case which is controlled by the Corporation, or (b) is or was serving, at
the written request of the Corporation or pursuant to an agreement in writing
with the Corporation which request or agreement provides for indemnification
under these By-laws, as a director, officer or employee of another corporation,
partnership, joint venture, trust or other enterprise not controlled by the
Corporation, provided that if such written request or agreement referred to in
this clause (b) provides for a lesser degree of indemnification by the
Corporation than that provided pursuant to this Article VII, the provisions
contained in or made pursuant to such written request or agreement shall
govern.  References above to "other enterprises" shall include employee benefit
plans and references to "serving at the request of the Corporation" shall
include any service as a director, officer or employee which imposes duties on,
or involves services by, such director, officer or employee with respect to an
employee benefit plan or its participants or beneficiaries.

                "D.G.C.L." means the Delaware General Corporation Law.

2 of this Article by reason of his Corporate Status.

                "Independent Counsel" means a law firm, or member of a law

matter material to either such party, or (ii) any other party to the Proceeding
giving rise to a claim for indemnification hereunder.

                "Matter" is a claim, a material issue, or a substantial request
for relief.

                "Proceeding" includes any action, suit, arbitration, alternate 
dispute resolution mechanism, investigation, administrative hearing or any other
proceeding whether civil, criminal, administrative or investigative, except one
initiated by an Indemnitee pursuant to Section 9 of this Article to enforce his
rights under this Article.

Directors (subject always to the power of the shareholders to change such
action); provided, however, that notice of the general nature of any such
action proposed to be taken shall be included in the notice of the meeting of
shareholders or of the Board of Directors at which such action is taken.

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 Caspian Corporation, Pennzoil Venezuela
Incorporated, Pennzoil Products Company, and Pennzoil Company (formerly Proven
Properties, Inc.) (collectively referred to herein as the Company) as of
December 31, 1995.  In accordance with the requirements of FASB 69, our
estimates of the Company's net proved reserves as of December 31, 1992, 1993,
1994, and 1995, 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 California, Louisiana, and
Texas.  The Company's foreign reserves are located in Canada, Venezuela, and
Azerbaijan.

                 The estimated reserve volumes and future income amounts
presented in this report are related to hydrocarbon prices.  December 1995
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 1995 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, 1995 are shown below:

</TABLE>


                 The "Liquid" reserves shown above are comprised of crude oil,
condensate, and natural gas liquids.  Natural gas liquids comprise 16 percent
of the Company's developed liquid reserves and

14 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, 1995 do not include 156,339
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,
1995.  In addition, the Company owns 83,317 long tons of sulfur reserves as of
December 31, 1995 which are not shown above; however, the revenue from these
sulfur reserves is included in the cash inflow data in this report.  Our
estimates of proved net reserves as of December 31, 1995 include 1,154,321
barrels and 4,702 MMCF for Pennzoil Venezuela, Inc. for which Pennzoil has a
contract to develop and produce but does not have actual ownership of the
hydrocarbons.

                 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 

<PAGE>   3
Pennzoil Company

Page 3

            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
tax as of December 31, 1995 from this report and as of December 31, 1994 from
our previous report are presented below.

(1) The cash inflow data for December 31, 1995 include revenues from 156,339 net
MMCF of carbon dioxide reserves which have a future net cash inflow before
income tax of $45,992,640 and present value at 10 percent before income tax of
$18,647,279.  The cash inflow data for December 31, 1994 include revenues from
160,678 net MMCF of carbon dioxide reserves which have a future net cash inflow
before income tax of $38,780,628 and present value at 10 percent before income
tax of $14,153,613.

(2) The cash inflow data for December 31, 1995 includes net cash inflow before
income tax of $4,665,490 and present value at 10 percent before income tax of
$3,257,189 attributable to Pennzoil Venezuela, Inc.

                 Our estimates as of December 31, 1995 and 1994 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.  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, in addition to the operating costs directly applicable to the individual
leases or wells.  The development costs were based on current data and include
certain 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, 1995 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 31,1995 and these prices were held constant to depletion of the
properties.  In accordance with SEC guidelines, changes in liquid prices
subsequent to December 31,1995 were not considered in this report.

                 The Alberta Royalty Tax Credit and the British Columbia Cost
of Service Allowance were not 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.  At the request of Pennzoil,
their estimate of zero net abandonment costs after salvage value for onshore
properties was used in this report.  Ryder Scott has not performed a detailed
study of the abandonment costs nor the salvage value and makes no warranty for
Pennzoil's estimate.  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 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 1995.

                 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.

                                        Very truly yours,

RE:      EVALUATION OF THE PETROLEUM AND NATURAL GAS PROPERTIES OF
         PENNZOIL CANADA, INC. EFFECTIVE DECEMBER 31, 1995


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, 1995.  In accordance with the requirements of
FASB 69, our estimates of the Company's net proved reserves as of December 31,
1993, 1994 and 1995 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 1995
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 1995 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, 1995 are shown below:

                 The "Liquid" reserves shown above are comprised of crude oil,
condensate and natural gas liquids.  Natural gas liquids (excluding condensate)
comprise 6.3 percent of the Company's developed liquid reserves and 6.4 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 369 long tons of sulphur reserves as of December 31, 1995 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
developed 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 developed 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, 1995 from this report and as of December 31, 1994 are
presented below.

                 Our estimates as of December 31, 1995, 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 1995 actual
pricing.

                 The Company has provided liquid prices in effect as at
November 30, 1995 and these prices were held constant to depletion of the
properties.  In accordance with SEC guidelines, changes in liquid prices
subsequent to November 30, 1995 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
1995.

                 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.
