ULTRAMAR DIAMOND SHAMROCK CORPORATION


                                     PART I

ITEM 1.  BUSINESS

Ultramar Diamond Shamrock Corporation (the "Company" or "UDS", formerly
Ultramar Corporation), was formed in April 1992 to acquire the United States
and Canadian refining and marketing operations of Ultramar PLC from LASMO plc,
a U.K. oil and gas exploration and production company.  On December 3, 1996,
Diamond Shamrock, Inc. ("Diamond Shamrock") merged with and into the Company
(the "Merger").  In connection with the Merger, the Company issued 29,876,507
shares of its Common Stock and 1,725,000 shares of its newly created 5%
Cumulative Convertible Preferred Stock in exchange for all the outstanding
Common Stock and 5% Cumulative Convertible Preferred Stock of Diamond Shamrock.
The shareholders of Diamond Shamrock received 1.02 shares of UDS Common Stock
for each share of Diamond Shamrock Common Stock and one share of UDS 5%
Cumulative Convertible Preferred Stock for each share of Diamond Shamrock 5%
Cumulative Convertible Preferred Stock.  The Company also amended its
certificate of incorporation to change its name from Ultramar Corporation to
Ultramar Diamond Shamrock Corporation.  The Common Stock is listed on the New
York and Montreal stock exchanges under the symbols "UDS" and "ULR,"
respectively.  UDS has approximately 17,200 employees and its principal
executive offices are located at 9830 Colonnade Boulevard, San Antonio, Texas
78230, (210) 641-6800.

The Company is a leading independent refiner and marketer of petroleum products
in the southwest United States (the "Southwest") and the northeast United
States and eastern Canada (collectively, the "Northeast").  In 1996, the
Company sold over 400,000 barrels per day ("BPD") of petroleum products and had
total revenues of $10.2 billion.  The Company is one of the largest independent
refining and marketing companies in the United States and the largest retail
marketer of gasoline in the state of Texas.  The Company owns and operates a
150,000 BPD refinery near Amarillo, Texas (the "McKee Refinery"), a 100,000 BPD
refinery in Los Angeles County, California (the "Wilmington Refinery") and an
90,000 BPD refinery near San Antonio, Texas (the"Three Rivers Refinery").  The
Company markets petroleum products and a broad range of convenience store items
and other merchandise in the Southwest under the Diamond Shamrock(R),
Beacon(R), and Ultramar(R) brand names through a network of 2,972 outlets
located across ten states.  The Company also stores and markets natural gas
liquids, manufactures and markets anhydrous ammonia and polymer-grade propylene
at its facilities at Mont Belvieu, near Houston, and operates certain other
related businesses in the Southwest.

The Company is also one of the largest independent petroleum refining and
marketing companies in the Northeast.  The Company owns and operates a 160,000
BPD refinery in St. Romuald, Quebec (the "Quebec Refinery") and markets
petroleum products through 1,320 retail outlets and 84 cardlocks.  The Company
is also one of the largest retail home heating oil companies in the Northeast,
selling heating oil to approximately 210,000 households.


THE COMPANY'S OPERATIONS

See Note 17 to the financial statements and "Management's Discussion and
Analysis of Financial Condition and Results of Operations" for financial
information regarding the Company and its domestic and foreign operations.
Southwest Refining

The Company owns and operates three modern refineries strategically located
near its key markets.  Two of the refineries are located in Texas, serving
markets in Texas and surrounding states.  The other southwestern refinery is
located in Wilmington, near Los Angeles, serving markets primarily in
California and Arizona.

The McKee Refinery, located near Amarillo, Texas, and the Three Rivers
Refinery, located near San Antonio, Texas, have an aggregate refining capacity
of approximately 225,000 BPD of throughput.  The Three Rivers Refinery relies
primarily on foreign crude oil for feedstock while the McKee Refinery uses a
varying blend of domestically produced





                                       3
   4
crude oils.  In 1996, the crude oil processed at the McKee Refinery had an
average gravity of 39.5degreesAPI, and a 0.25wt% sulfur content.  Crude oil
processed at the Three Rivers Refinery had an average gravity of 37.2 degrees 
API and a 0.25wt% sulfur content.  The Company operated the McKee and Three 
Rivers refineries at levels which averaged 96% of capacity in 1996.
Approximately 94% of the refinery output was light end products, including
gasoline, diesel, jet fuels, and liquefied petroleum gases.  The refineries also
produce sulfur, sulfuric acid, ammonium thiosulfate, refinery grade propylene,
fuel oil, asphalt and carbon black oil.

The Wilmington Refinery is capable of processing over 100,000 BPD of total
throughput, including over 70,000 BPD of crude oil and, because of additional
capacity in its downstream units, over 30,000 BPD of partially refined
feedstocks and blendstocks.  Like other California refineries, the Wilmington
Refinery operates principally on a blend of Californian and Alaskan North Slope
crude oils, supplemented, to a limited extent, by foreign crude oils.  Given
its coking and desulfurizing capabilities, the Wilmington Refinery is
particularly well suited to process heavy, high-sulfur crude oils, which
historically have cost less than other crude oils.  In 1996, the Wilmington
Refinery's processing stream was comprised of approximately 32% heavy sour
crude oil, 40% heavy crude oil and 28% of the more expensive Alaskan North
Slope crude oil (or its equivalent).  In 1996, the crude oil processed at the
Wilmington Refinery had an average gravity of 22 degrees API and a 2.1wt% sulfur
content.

The McKee Refinery supplies conventional gasoline and, since 1994, Federal
specification reformulated gasoline ("RFG") and other oxygenated gasoline, to
markets in Texas and surrounding states.  A portion of the oxygenates used in
manufacturing RFG and other oxygenated gasoline is manufactured at the McKee
Refinery and the balance is obtained from other manufacturers.  The McKee plant
also manufactures low-sulfur diesel meeting governmental specifications for
on-road use.

During 1995 and 1996, the Company completed work on several expansion projects
at its Three Rivers Refinery which allow the refinery to be more flexible in
selecting its crude oil feedstock, to upgrade its product slate and to expand
its throughput capacity to approximately 90,000 BPD.  The projects included a
demetalized oil hydrotreater, a hydrogen plant, a sulphur recovery plant and
expansion of the crude unit.  The final phase of the expansion, the heavy
gasoil hydrotreater, was completed during the third quarter of 1996.

The Three Rivers Refinery began processing natural gas liquids ("NGL") from
local gas processing plants in early 1995.  A 50-mile pipeline and
modifications to existing equipment were completed in March 1996 to enable the
Three Rivers plant to produce and transport a purity ethane product to a
commercial ethylene plant for processing.

The Company is nearing completion of a benzene/toluene/xylene ("BTX")
extraction and fractionation unit at the Three Rivers Refinery, which will
enable the Company to recover these valuable petrochemical feedstocks from the
refinery's gasoline pool.  Completion of the BTX unit is scheduled for the
first quarter of 1997.

The Wilmington Refinery produces unleaded gasolines, diesel fuel, jet fuel,
petroleum coke and other unfinished products.  In 1996, the Wilmington Refinery
had an average throughput of 102,700 BPD with a saleable yield of approximately
101%, including a light products yield of approximately 92%.  In 1996, the
Wilmington Refinery produced 53,400 BPD of unleaded gasoline and 31,100 BPD of
distillate, of which 26,200 BPD was jet and diesel fuel.

The Wilmington Refinery is the newest refinery in California and one of the
most modern, technologically-advanced and energy-efficient refineries in North
America.  The majority of its facilities were constructed in the early 1980s
and were built to comply with environmental regulations and permitting
requirements applicable to newly constructed facilities in California which
were in many respects more stringent than those applicable to then existing
facilities.  In September 1994, the Company completed the construction of a
naphtha hydrotreating unit, enabling the Wilmington Refinery to produce 100%
Federal specification RFG.  In the first quarter of 1996, the Company completed
a capital program which enabled the refinery to produce 100% California Air
Resources Board ("CARB") specification reformulated gasoline.  The Company also
completed the construction of a high-pressure gasoil hydrotreating unit (the
"GOH") in 1996, which increased the capacity of the Wilmington Refinery to
produce finished product and enabled the refinery to run a lower cost, higher
sulfur gasoil and additional lower cost, heavy, higher sulfur crude oils.
Completion of these two projects





                                       4

increased throughput capacity at the Wilmington Refinery by 10,000 BPD to
100,000 BPD.

Operations - Capital Expenditures".

Southwest Supply and Distribution

The ability to supply the Company's refineries from a variety of sources is
essential to remain competitive. The Company's network of crude oil pipelines
gives the Company the ability to acquire crude oil from producing leases, major
domestic oil trading centers and Gulf and West Coast ports and to transport
crude oil to the Company's southwestern refineries at a competitive cost.

The McKee Refinery has access to crude oil from the Texas Panhandle, Oklahoma,
southwestern Kansas and eastern Colorado through approximately 1,223 miles of
crude oil pipeline owned or leased by the Company. This refinery is also
connected by common carrier pipelines to major crude oil centers in Cushing,
Oklahoma and Midland, Texas.  The McKee Refinery also has access at Wichita
Falls, Texas to major pipelines which transport crude oil from the Texas Gulf
Coast and major West Texas oil fields into the Mid-Continent region.  The
Company has tankage to store approximately 520,000 barrels of crude oil at the
McKee Refinery and tankage to store an additional 928,000 barrels throughout
the system supplying crude oil to the refinery.

The Three Rivers Refinery has access to crude oil from foreign sources
delivered to the Texas Gulf Coast at Corpus Christi, Texas, as well as crude
oil from domestic sources.   A new crude oil terminal in Corpus Christi, which
has a total storage capacity of 1.6 million barrels, was added in 1995 to
enhance its access to foreign crude oil.  The addition of a fourth 400,000
barrel tank to the terminal in the first half of 1996 enables the Company to be
more flexible in taking delivery of and in blending crude oil feedstock for the
Three Rivers Refinery.  The addition of the new tank should also reduce the
Company's demurrage expense (the charge assessed by a ship for the time it is
delayed in port to unload cargo) by allowing the Company to accept delivery of
larger crude oil cargos at the terminal, thereby decreasing the number of such
deliveries and reduce transportation expense by eliminating the need to
terminal a portion of the Company's crude oil receipts through facilities
located near Corpus Christi which are owned by other parties. The Corpus
Christi crude oil terminal is connected to the Three Rivers Refinery by a 92
mile pipeline which has the capacity to deliver 120,000 barrels of crude oil
per day to the refinery.  The Three Rivers Refinery also has access to West
Texas Intermediate crude oil through common carrier pipelines and to crude oil
production in South Texas.

The Wilmington Refinery has 2.8 million barrels of storage capacity and is
connected by pipeline to marine terminals and associated dock facilities, which
can be utilized for movement and storage of crude oil, feedstocks, gasoline
blending components and fuel oil blendstocks.  The Company operates a product
marine terminal and a dock facility which are leased from the Port of Los
Angeles and the Company owns tanks at the marine terminal with a storage
capacity of 980,000 barrels.

The Company acquires a  portion of its crude oil requirements through the
purchase of futures contracts on the New York Mercantile Exchange.  The Company
also uses the futures market to manage the price risk inherent in purchasing
crude oil in advance of the delivery date and in maintaining its inventories.

The Company has access to a large supply of crude oil from both domestic and
foreign sources, most of which is obtained under short-term supply agreements.
Although the Company has no crude oil reserves and therefore its operations
could be adversely affected by fluctuations in availability of crude oil and
other supplies, the Company believes that it is currently advantageous to
maintain short-term supply agreements to enable the Company to purchase crude
oil at attractive prices.  Feedstocks are also obtained from a variety of
refineries under short-term supply agreements.  The Company believes that the
current sources of crude oil and feedstocks will be sufficient to meet
substantially all the Company's requirements for the foreseeable future.

The Company has a long-term contract for the supply of hydrogen to the
Wilmington Refinery which is sufficient to meet its increased need as a result
of the operation of the GOH and new environmental regulations which became
effective





                                       5
   6
in 1996 and a long-term contract for the supply of hydrogen to the Three Rivers
Refinery hydrocracker which is sufficient to supply hydrogen to the
hydrocracker in quantities required beyond those produced at the Three Rivers
Refinery.

Refined products produced at the McKee and Three Rivers refineries are
distributed primarily through approximately 3,357 miles of refined products
pipelines and 14 terminals.  The Company's refined products terminal at
Southlake,  near Dallas, also receives products from the Explorer Pipeline, a
major common carrier of refined products from the Houston area.

Over the last several years, the Company has added significantly to its product
distribution system, in part by the construction of new product pipelines to
connect the Company's refineries to expanding markets and, in part, by adding
to or purchasing additional capacity in existing product pipelines.

In November 1995, the Company commenced operation of a newly-constructed,
408-mile, 10-inch pipeline from the McKee Refinery to El Paso, Texas, along
with a terminal in El Paso from which the Company distributes product delivered
via the pipeline.  The pipeline can currently deliver 30,000 BPD of refined
products, including gasoline, diesel, jet fuels and propane, and the new
terminal provides storage capacity for approximately 500,000 barrels of
product.  The pipeline gives the Company the ability to deliver refined
products from the McKee Refinery directly to the El Paso market, in which the
Company has established a significant market presence, and to deliver refined
products to markets in Arizona through a common carrier pipeline originating in
El Paso.  The Company has announced plans to expand the delivery capacity of
the El Paso pipeline to 40,000 barrels per day in 1997.

Available capacity in the Amarillo-Tucumcari-Albuquerque products pipeline,
which carries products from the McKee Refinery, has been expanded both by the
purchase of the one-half interest of a pipeline partner and by construction
projects that expanded the capacity of that line by an additional 2,000 BPD,
giving the line a total product delivery capacity from the McKee Refinery of
12,600 BPD.  The Company has announced plans to cooperate with the other joint
owner of the pipeline to expand its total carrying capacity from 23,000 BPD to
32,000 BPD in 1997.

In 1994, the Company completed construction of a products pipeline from the
McKee Refinery to the Colorado Springs, Colorado area.  The project included a
10-inch pipeline to Colorado Springs, Colorado with an initial capacity of
32,000 BPD, covering approximately 258 miles, which connects to a new terminal
facility with a total product storage capacity of 320,000 barrels.  In 1996,
the Company extended the pipeline to its Denver terminal.

Refined petroleum products are distributed from the Wilmington Refinery by
pipeline to a network of product terminals owned by third parties in Southern
California, Nevada and Arizona, and then on to the Company's retail stations
and wholesale customers.

In addition to its product pipelines and terminals, the Company has
historically entered into product exchange and purchase agreements which enable
it to minimize transportation costs, balance product availability, broaden
geographical distribution capabilities and supply markets not connected to its
refined products pipeline system.  Exchange agreements provide for the delivery
of refined products to unaffiliated companies at the Company's terminals in
exchange for delivery of a similar amount of refined products to the Company by
such unaffiliated companies at agreed locations.  Purchase agreements involve
the purchase by the Company of refined products from unaffiliated companies
with delivery occurring at agreed locations.  Products are currently received
on exchange or by purchase through 69 terminals and distribution points
throughout the Company's principal marketing areas.  Most of the Company's
exchanges and purchase arrangements are long-standing arrangements, but
generally can be terminated on 30 to 90 days notice.  The Company believes it
is unlikely that there will be an interruption in its ability to exchange
refined product in the foreseeable future.

Southwest Marketing

The Company is one of the largest independent retail marketers of petroleum
products in the Southwest.  The Company has a strong brand identification in
much of its ten-state marketing area, including Texas, California, Colorado,
Louisiana, New Mexico and Oklahoma.  Gasoline and diesel fuel are sold under
the Diamond Shamrock(R), Beacon(R) and Ultramar(R) brand names through a
network of 2,972 company and dealer operated retail outlets.  In 1996, the
Company's total marketing sales (wholesale and retail) of refined product in
its southwest market averaged 416,600 BPD.  The Company has one of the highest
average sales volumes per service station in the southwest, with sales per
company-operated station averaging 74,500 gallons per month during 1996.  The
volume of gasoline sold through the company-operated network of 1,600
southwestern retail outlets during 1996 equaled approximately 54% of the
gasoline the Company produced at its three southwestern refineries.  The volume
of gasoline the Company sold to independent branded and unbranded dealers and
jobbers, commercial and end user accounts and other resellers exceeded the
remainder of the Company's gasoline production.  To the extent the Company's
requirements exceed the production at its refineries, the Company purchases
product for resale.

Total retail outlets at the dates indicated below were as follows:

During the three-year period ended December 31, 1996, the Company acquired or
constructed 957 retail outlets in  the Southwest.  The Company plans to acquire
or construct approximately 22 sites in 1997, most of which will be located in
Arizona.  See "Management's Discussion and Analysis of Financial Condition and
Results of Operations - Capital Expenditures."

In December 1995, the Company acquired National Convenience Stores Incorporated
("NCS"), which became a wholly owned subsidiary of the Company.  At the time of
its acquisition, NCS operated 661 specialty convenience stores, over 90% of
which sold gasoline in four cities in the state of Texas under the name Stop N
Go.  During 1996, the Company began integrating the NCS stores with the rest of
the Company's retail operations and began selling Diamond Shamrock branded
gasoline through most of its Stop N Go outlets.  The Company continues to use
the Stop N Go name for most of the NCS convenience stores.

As of December 31, 1996, company-operated retail outlets in the southwestern
market were located in Texas (1,203), California (170), Colorado (129), New
Mexico (45), Louisiana (35) and Arizona (18).  Most of the Company's company-
operated retail outlets are modern, attractive, high-volume gasoline outlets.
In addition, these outlets sell a wide variety of products such as groceries,
health and beauty aids, fast foods and beverages.

The Company has an ongoing program to modernize and upgrade the retail outlets
it operates.  These efforts are designed to improve appearances and to create a
uniform look easily recognizable by customers.  Exterior improvements generally
include the installation of new price signs, lighting and canopies over the
gasoline pumping areas.  The program also includes the installation of
computer-controlled pumping equipment and the renovation of interiors.

The Company is continuing its program of closing and selling retail outlets
which have marginal profitability or which are situated outside its principal
marketing areas.  During 1996, the Company closed or sold 102 such outlets.

   8
As of December 31, 1996, independent dealers and jobbers operated 1,372 Diamond
Shamrock(R), Beacon(R) or Ultramar(R) branded retail outlets.  The Company
enjoys long-term relationships with many of its independent dealers.

The Company's competitive position is supported by its own proprietary credit
card programs, which had approximately 965,000 active accounts at the end of
1996.  The Company currently utilizes electronic point-of-sale credit card
processing ("POS") at most of its Company and dealer operated stores.  POS
reduces transaction time at the sales counter and lowers the Company's credit
card program costs by reducing float, reducing charges paid by the Company  to
accept other companies' credit cards for purchases, eliminating postage and
insurance costs and reducing bad debts. The Company has instituted a program of
installing dispenser-mounted credit card readers at high volume company
operated retail locations.

In June 1994, the Company completed the installation of a computer based,
intelligent retail information system ("IRIS") at its company-operated Diamond
Shamrock(R) stores. IRIS incorporates an enhanced POS system and will automate
inventory control, pricing and sales tracking.  IRIS interfaces with the
Company's new dispenser-mounted credit card readers and the continuous
underground storage tank monitoring system now being installed  by the Company.
During 1996, the Company integrated its NCS stores into the electronic data
processing system and, during 1997, plans to begin integrating its Beacon(R)
and Ultramar(R) company-operated sites.

Southwest Petrochemical and Allied Businesses

In addition to its core refining and marketing businesses, the Company is
engaged in several related businesses.  The most significant are described
below.

The Company owns and operates large underground natural gas liquids and
petrochemical storage and distribution facilities located at the Mont Belvieu
salt dome, northeast of Houston.  The facilities have total permitted storage
capacity of approximately 77 million barrels and consist of 30 wells.  The
facilities are used for storing and distributing ethane, ethane/propane mix,
ethylene, propane, natural gasoline, butane and isobutane, as well as refinery,
chemical-grade and polymer-grade propylene.  The Mont Belvieu facilities
receive products from the McKee Refinery through the Skelly-Belvieu pipeline
(which the Company operates and in which it owns a 50% interest), as well as
from local fractionators and through major pipelines coming from the
Mid-Continent region, West Texas and New Mexico.  In 1996, an average of
approximately 261,700 BPD of natural gas liquids and petrochemicals moved
through the facilities and were distributed via an extensive network of
pipeline connections to various refineries and petrochemical complexes on the
Texas and Louisiana Gulf Coasts, earning various storage and distribution fees
for the Company.

During the third quarter of 1996, the Company completed construction of a
second propane/propylene splitter at its Mont Belvieu hydrocarbon storage
facility.  A subsidiary of American PetroFina, Inc. ("Fina") has a one-third
interest in the two splitters.  The Company and Fina each pay their
proportionate share of the costs and receive in kind their proportionate share
of the products produced at the plant.

The two splitters are capable of producing approximately 1.6 billion pounds of
polymer-grade propylene per year.  Polymer-grade propylene is a feedstock used
in the manufacture of plastics.  The plant utilizes refinery-grade propylene
produced by the McKee and Three Rivers Refineries and other refineries for
feedstock.  The Company's storage facilities at Mont Belvieu are used to store
feedstock for the splitters and polymer-grade propylene after it is produced.
The product is distributed by pipeline to purchasers in the Houston Ship
Channel area and to export facilities.  In 1996, the Company's share of
production from the splitters totaled over 736 million pounds of polymer-grade
propylene and the Company was successful in marketing product in excess of that
amount.

A petrochemical export terminal located on the Houston Ship Channel in which
the Company has a joint venture interest was completed and commenced operation
in August 1992.  The terminal is connected by pipeline to the Company's
splitters and petrochemical storage facilities at Mont Belvieu.  The terminal
provides the Company with access to international petrochemical markets.





                                       8
   9
The Company indirectly owns approximately 34% of the outstanding shares of Sol
Petroleo, S.A. ("Sol"), an Argentine company headquartered in Buenos Aires,
whose shares are publicly traded on the Argentine stock exchange.  Sol
currently markets gasoline under the Sol brand through 102 retail gasoline
outlets and convenience stores in Argentina, 12 of which are Sol-operated and
90 of which are operated by independent dealers.  In May 1996, Sol purchased
Carboclor Industrias Quimicas S.A., an Argentine corporation in the business of
manufacturing petrochemicals.

In January 1997, the Company sold its 75% interest in a Bolivian oil and gas
exploration and production operation.  The Bolivian operations were owned
jointly by a wholly-owned subsidiary of the Company and Phoebus Energy, Ltd., a
Bermuda corporation in which the Company owns a 50% interest.

The Company also sold a substantial portion of its wholly-owned subsidiary,
North American InTeleCom, Inc. ("NAI"), during 1996 and sold its remaining
interest in early 1997.  NAI operates telephone systems for use by inmates in
correctional facilities, provides pay telephone services, manages the pay
telephone accounts of several regional retailers and provides prepaid calling
card services.

Northeast Refining

The Quebec Refinery has a capacity of 160,000 BPD and is one of the most modern
and efficient refineries in Canada.  The refinery's capacity has been expanded
by 40,000 BPD over the last four years as the result of a relatively low cost
debottlenecking and reconfiguration of the crude and fluid catalytic cracking
units.  In 1996, the Quebec Refinery's processing stream was comprised of
approximately 56.2% light, sweet crude oil (including Heidrun crude oil), 41.5%
medium crude oil, 1.3% heavy, asphaltic crude oil and 1.0% condensate.  The
crude oil processed at the refinery had an average gravity of 33.5 degrees API
and a 0.29wt% sulfur content.

In 1996, the Quebec Refinery had an average throughput of 143,900 BPD with a
saleable yield of approximately 99.6%, including a light products yield of
approximately 87.0%.  In 1996, the refinery manufactured 142,300 BPD of product
of which 61,100 BPD was gasoline, 60,100 BPD was distillate, including diesel
fuel and home heating oil and 21,100 BPD was other products, principally heavy
fuel oil and asphalt. In 1996, the total sales of refined products for the
Northeast averaged 159,000 BPD.

Northeast Supply and Distribution

The Quebec Refinery receives crude oil by ship at its deep-water dock.  The
location of the refinery and the water depth of the St. Lawrence River at the
dock allow the refinery to receive year-round shipments of crude oil on large
crude oil tankers.  The Company's ability to receive one million barrel cargoes
offers a significant advantage over the two other Quebec Province refiners,
which are located in Montreal and typically receive crude oil by pipeline from
Portland, Maine, following ocean shipment in smaller cargo sizes.  The Company
has time charters on three large crude oil carrying vessels which are
double-bottomed and double-hulled and are capable of navigating the St.
Lawrence River in the winter.  They provide the base shipping requirements for
transportation to the Quebec Refinery and are supplemented by short-term and
single voyage charters.  The Quebec Refinery has storage capacity for more than
eight million barrels of crude oil, intermediate and refined products as well
as pressurized storage for liquefied petroleum gas.

The Company has supply contracts with major international oil companies which
supply the Quebec Refinery's requirements for light, sweet crude oils from the
North Sea and West Africa, principally on a spot market price basis.  The
Company obtains the majority of its heavy asphaltic crude oils from Venezuela.
In addition, the Company purchases crude oils and feedstocks on the spot market
when it is economically advantageous to do so.  The Company believes that there
are extensive supplies of light, sweet crude oils available to it in the
foreseeable future. While the Company has no crude oil reserves and therefore
its operations could be adversely affected by fluctuations in availability of
crude oil and other supplies, the Company believes that, given the wide
availability of North Sea and West African crude oils in the international
market, its operations would not be materially adversely affected if its
existing supply contracts were canceled.





                                       9
   10
Refined product is transported from the Quebec Refinery by coastal ship, truck
and railroad tank car.  The Company operates a distribution network of
approximately 71 bulk storage facilities throughout the Northeast, including 23
terminals.  Reciprocal product exchange arrangements with other refiners are
used to minimize transportation costs, optimize refinery utilization and
balance product availability in particular locations with marketing demands.
About 40% of the Quebec Refinery's light products yield is exchanged with major
Canadian refining and marketing companies, with the Company supplying product
at the Quebec Refinery and, to a lesser extent, in Montreal, and receiving
product at multiple locations in the Provinces of Quebec, Ontario, the
Maritimes and Newfoundland.

Northeast Marketing

The Company is a major supplier of refined petroleum products in eastern
Canada, serving Quebec, Ontario and the Atlantic Provinces of Newfoundland,
Nova Scotia, New Brunswick and Prince Edward Island.  In addition, during 1996,
the Company expanded its home heating oil business into the northeastern United
States by acquiring several  home heating oil operations in Massachusetts, New
York and Vermont.  In 1996, the Company's total marketing sales (wholesale and
retail) of refined product averaged 159,000 BPD.  Motorist sales volume at
company and dealer operated sites averaged 39,500 gallons per month per station
in 1996.

The Company sold gasoline and diesel fuel through a network of 1,320 branded
service stations and 84 cardlocks located throughout eastern Canada in 1996.
Approximately 78.0% of these facilities are branded Ultramar(R), with the
Sergaz(R), XL(R) and Pipeline(R) brands also used.  During 1995, the Company
initiated a program to convert a major portion of its retail network from
lessee and agent-operated to company-operated sites and to add approximately
450 convenience stores to its network over the next several years.  At December
31, 1996, Ultramar operated 139 of the 617 service stations it owned or
controlled under long-term lease.  In addition, the Company distributed
gasoline through another 703 branded dealer locations throughout this market
which are owned or controlled by independent business people.  The remaining
service station sites in the Canadian network are owned or leased by station
operators and are supplied under independent dealership agreements.  See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations - Capital Expenditures."

The Company has one of the largest home heating oil operations in North
America.  In 1996, Ultramar sold home heating oil to approximately 210,000
households in eastern Canada and the United States.  The development of the
Company's Northeast heating oil business is progressing slightly ahead of the
plan adopted in the Fall of 1995.  During 1996 acquisitions added approximately
35,000 heating oil customers.  The Company has one of the largest cardlock
operations in the Northeast, servicing approximately 6,400 accounts through
eighty-four cardlocks.  A cardlock is a card or key- activated, self-service,
unattended pump installation that allows commercial fleets, trucking companies
and government fleets to buy transportation fuels on account twenty-four hours
per day.  In addition, the Company supplies more than 2,160 commercial and
industrial accounts and approximately 260 branded and unbranded wholesale
customers.


COMPETITIVE CONSIDERATIONS

The Company's refineries and supply and distribution networks are strategically
found to serve its markets.  The Company consistently sells more a refined
product than its refineries produce, purchasing its additional requirements in
the spot market.  This strategy has enabled the Company to operate its
refineries at high rates while allowing for incremental refinery capacity
expansions to be quickly utilized upon completion.

Quality products and strong brand identification have positioned the Company as
the largest marketer of motor fuels in Texas, with a market share of
approximately 15%, and the second largest independent marketer in California,
with a market share of approximately 7%.  The Company also has significant
branded gasoline market shares in Colorado, New Mexico and Louisiana.  In
Quebec, the Company is the largest independent marketer of motor fuels with a
market share in excess of 23%.  The Company also has a substantial share of the
motor fuels market in the Atlantic Provinces.

The retail markets have historically been highly competitive.  Competitors
include a number of well capitalized and fully-integrated major oil companies
and both large and small independent operators.  Industry studies indicate that
over the past several years, the retail markets have been characterized by
several significant trends including (i) increased store rationalization by
retailers to fewer geographic regions and (ii) increased consumer emphasis on
convenience.  Additionally, operators have closed marginal and unprofitable
locations as a result of increasing environmental regulations requiring
replacement of underground storage tanks.  Industry studies indicate that
consumer buying behavior continues to reflect the effect of increasing demands
on consumer time.  Convenience and the time required to make a purchase are
increasingly important considerations in buying decisions.  The Company
believes these two trends may result in opportunities to increase market share
in the Company's core markets.

The Company's earnings and cash flow from operations are primarily dependent
upon processing crude oil and selling quantities of refined products at
refining and retail marketing margins sufficient to cover fixed and variable
expenses.  Crude oil and refined products are commodities.  Crude oil costs and
refined product prices depend on numerous factors beyond the Company's control,
including the supply of and demand for crude oil, gasoline and other refined
products which in turn depend on, among other factors, changes in domestic and
foreign economies and production levels, the availability of imports, the
marketing of competitive fuels, political affairs and the extent of government
regulation.  The prices received by the Company for its refined products are
affected by regional factors, such as product pipeline capacity, local market
conditions and the level of operations of competing refineries.  A large, rapid
increase in crude oil prices would adversely affect the Company's operating
margins if the increased cost of raw materials could not be passed on to the
Company's customers.  In recent years, crude oil costs and prices of refined
products have fluctuated substantially.  The industry also tends to be seasonal
with increased demand for gasoline during the summer driving season and, in the
Northeast, for home heating oil during the winter.


REGULATORY MATTERS

Environmental

The Company's refining and marketing operations are subject to a variety of
laws and regulations in the U.S. and Canada governing the discharge of
contaminants into, or otherwise relating to, the environment.  The Company
believes that its operations are in substantial compliance with all applicable
environmental laws.

The principal environmental risks associated with the Company's operations are
emissions into the air and releases to soil or groundwater.  The unintended
release of emissions at refineries, terminals and service stations and from
ships, trains, pipelines and trucks may occur despite stringent operational
controls and the best management practices.  Such releases may give rise to
liability under environmental laws and regulations in the U.S. and Canada
relating to contamination of air, soil, groundwater and surface waters.  The
Company employs personnel specifically trained to prevent occurrences and to
address and remediate these problems in the event they arise.  In addition, the
Company has adopted policies, practices and procedures in the areas of
pollution control, product safety and occupational health; the production,
handling, storage, use and transportation of refined petroleum products; and
the storage, use and disposal of hazardous materials, designed to prevent
material environmental or other damage and the material financial liability
which could result from such events.

The total cost for environmental assessment and remediation depends on a
variety of regulatory standards, some of which cannot be anticipated.  The
Company establishes environmental accruals when site restoration and
environmental remediation and clean up obligations are either known or
considered probable and can be reasonably estimated.  Accruals for
environmental matters amounted to approximately $151.4 million at December 31,
1996.  These accruals include Southwest Operations - $129.6 million and
Northeast Operations - $21.8 million.

The Company believes that its environmental risks will not, individually or in
the aggregate, have a material adverse effect on its financial or competitive
position.  See "Legal Proceedings--Environmental" for a discussion of legal





                                       11
   12
proceedings involving the Company relating to environmental matters.

Southwest Operations

During 1996, two Agreed Orders were entered into with the Texas Natural
Resource Conservation Commission for the McKee and Three Rivers refineries.
The McKee Order resolved alleged violations concerning the injection of treated
refinery wastewater.  The Three Rivers Order dealt with alleged solid and
hazardous waste violations.  The Company has met the terms and conditions of
and is in compliance with both Orders.  The estimated ongoing costs associated
with these items have been accrued.

In December 1996, the United States Environmental Protection Agency filed
Requests for Information from the McKee and Three Rivers Refineries.  The
Requests for Information, relating to hazardous waste and Clean Air Act
compliance issues, substantially reflected the Company's disclosures to the
Texas Natural Resource Conversation Commission upon completion of audits at
those facilities conducted pursuant to the Texas Environmental, Health and
Safety Audit Privilege Act (the "Audit Act").

Regulations issued by the EPA require underground storage tanks to be upgraded
by December 1998.  The Company has met all interim deadlines and has upgraded
approximately 90% of its systems to the 1998 standards and plans to complete it
upgrade program by December 1998.  The anticipated assessment and remediation
costs associated with the program are included in the liability reserve
previously mentioned.

The Company has accrued liabilities for environmental remediation obligations
at various sites, including four multiparty sites where the Company has been
identified as a potentially responsible party ("PRP").  The involvement of
other  financially responsible parties mitigates the Company's exposure at
these sites.

In 1990, Ultramar Inc., a wholly owned subsidiary of the Company ("UI"), was
notified that it had been named as one of approximately 90 Potentially
Responsible Parties ("PRP") by the U.S. Environmental Protection Agency in
connection with the Purity Oil Superfund site in Fresno, California.  The site
was allegedly used by the PRPs, including branches of the U.S. military, as a
waste disposal site and waste oil recycling facility.  Preliminary
investigations of the site indicate that off-site groundwater contamination has
occurred.  The EPA served an administrative order requiring certain of the PRPs
to undertake remediation of the site.  No such order has been served on UI, nor
is the Company aware of any current intention on the part of the EPA to serve
such an order on UI, nor any intent on the part of any other PRP to assert
liability against the Company.  The Company's review of the information on
which the EPA bases its claim of PRP status has revealed no facts to support
the claim that the Company disposed of waste at the site.  At this point, the
remediation is in the second of three stages and the current estimate for
clean-up for the entire site is approximately $40.0 million.  The Company is
participating in an alternative dispute resolution process with the EPA's
Department of Toxic Substances Control and many of the other PRPs as a means to
resolve each PRP's proportionate share of the liability.  The Company's
expenditures to date have been minimal as the Company has not been one of the
parties against which the EPA has established liability.

In 1985, UI was named as one of four responsible parties at the Kings County
Dump site, a former municipal landfill.  The primary responsible party is the
Kings County Waste Management Authority, which owns the site and whose
predecessor operated the site.  The Company believes that UI's involvement with
this site stems from its predecessor's authorized disposal of spent refinery
caustic between 1954 and 1964.  The Company is cooperating with the Kings
County Waste Management Authority to assess the contamination at the site.
Preliminary findings indicate that this site was used for municipal solid waste
disposal and for disposal of industrial and agricultural waste which are
unrelated to the Company's operations.  To date, the Company has spent
approximately $1.0 million in its collaborative efforts with the Kings County
Waste Management Authority to assess and partially remediate the site.
However, there is no current estimate of the total cost of remediation.





                                       12
   13
In February 1994, UI received notification from the California Environmental
Protection Agency, Department of Toxic Substances Control ("DTSC") that UI may
be a PRP with respect to a state Superfund site involving a former waste
management company known as TCL Industries (the "TCL Site").  During the 1950s
and 1960s, TCL Industries operated sumps that accepted oil field production and
other potentially hazardous wastes.  The entire TCL Site is approximately 200
acres.  UI owns approximately 24 acres that were acquired from the former owner
of the Wilmington Refinery that may be within the TCL Site.  TCL Industries did
not operate on any portion of the 24-acre parcel, although the former owner
maintained sumps on that parcel in which oil field production wastes were
disposed.  The acquisition agreement with the former owner provides that they
will be the PRP with respect to the TCL Site and that any liability UI incurs
in connection with the TCL Site will be covered by indemnification provisions
that limit UI's aggregate exposure through 2008 to $15.0 million for all costs
for contamination resulting from activities prior to the Company's acquisition
of the Wilmington Refinery to the extent the costs result from a study or
remediation that is required by a governmental directive.  At this time, the
Company is unable to determine the extent of its liability, if any, on the TCL
Site or evaluate the extent or cost of clean up on its portion of the TCL Site.
Due to the indemnification arrangement with the former owner of the Wilmington
Refinery, the Company does not believe that liability arising out of the TCL
Site, if any, would have a material adverse effect on its operations or
financial position.

In Texas, the Freddie Harris State Superfund Site involves the cleanup of
acidic asphalt sludges which were disposed of at a sand and gravel operation by
an acquired company in the late 1960's.  The Company is the lone remaining
viable party to handle this remediation.

The Waste Oil Tank Services State Superfund Site located in Houston, Texas, is
the site of a used oil recycling business which was sold by the Company in
1979.  The Company, along with approximately 12 other parties, is responsible
for remediation of this site.  Removal activities took place at the site in
1996.

In 1991, the Company, along with one other party, entered into a
Non-Interference Order with the EPA concerning alleged hydrocarbon
contamination from a 1968 pipeline release in Albuquerque.  The Company is
working closely with the EPA and State of New Mexico and has installed a soil
venting system.

Northeast Operations

The Company has spent over $10.7 million during the past three years on capital
expenditures required to comply with various Canadian, Provincial and other
environmental rules and regulations and has budgeted approximately $19.4
million for environmental capital expenditures in 1997.  As with its Southwest
operations, much of the capital spent by the Company in the Northeast for
environmental compliance is integrally related to projects that increase
refinery capacity or improve product mix and the Company does not specifically
identify capital expenditures related to such projects on the basis of
environmental as opposed to economic purpose.

The Company has ongoing projects to assess and remediate certain contamination
at its Northeast facilities, including contamination from the on-site disposal
of sludges, residues and tank bottoms at its Quebec Refinery and Halifax
terminal (the site of the Company's former Halifax Refinery).  Based on
findings to date, the Company believes that the reserve previously mentioned is
appropriate in light of anticipated environmental assessment and remediation
costs for these facilities.

The Company voluntarily implemented an ongoing, comprehensive underground
storage tank upgrade program, which includes soil and groundwater remediation
where necessary.  To date, the program has resulted in upgrading the
underground tanks at approximately 95% of the 617 company-owned and leased
service stations.  The Company believes that the reserve previously mentioned
is sufficient to cover the costs of soil and groundwater remediation at the
remaining service stations.  The Company anticipates that this program will
greatly reduce the likelihood of unanticipated releases of refined products in
the future.

The Company, together with the Quebec Ministry of Environment and the Montreal
Urban Community, is investigating the presence of free phase hydrocarbons
discovered in an area adjacent to underground pipelines serving the Company's





                                       13
   14
Montreal East terminal.   The Company has yet to determine if it is responsible
for the contamination as the pipelines are located in a corridor shared by
several other terminals and businesses operating in the area.  In addition, the
Company has notified the Ministry of  subsurface contamination in the vicinity
of an oil-water separator at the Quebec Refinery which exceeds the Ministry's
guidelines for oil and grease at commercial industrial sites.  At this time,
the Company is unable to determine the extent of its liability, if any, at the
pipeline site or evaluate the extent or cost of clean up at the pipeline or
refinery sites.  However, the Company does not believe that the resulting
liability, if any, would have a material adverse effect on its operations or
financial position.

The Company believes that the Quebec provincial government will issue new
refinery effluent regulations in 1998 that, if adopted, will require

ITEM 2.  PROPERTIES

The Company owns the McKee, Three Rivers, Quebec and Wilmington Refineries and
related facilities in fee. The Company also owned approximately 1,223 miles of
crude oil pipelines and 3,357 miles of refined product pipelines at the end of
1996.  Forty-one miles of the Company's crude oil pipelines and 1,246 miles of
its refined products pipelines were owned jointly with one or more other
companies.  The Company's interests in such pipelines were between 30% and 54%.
At December 31, 1996, the Company owned 71 bulk storage facilities in the
Northeast.  The Company also owned 14 products terminals in the Southwest.
Thirteen of the terminals were 100% owned by the Company and one terminal was
owned 60% by the Company.  The Company leases the property on which its Corpus
Christi crude oil terminal is situated, under a lease which has 17 years
remaining under its primary term, followed by six consecutive five year renewal
options.

The principal properties used in the Company's marketing operations at the end
of 1996 were 1,737 company-operated retail outlets, 881 of which were owned in
fee and 856 of which were leased.  Of the leased outlets, 199 were leased to
the Company pursuant to a $190.0 million lease facility expiring in December
2003.  At the end of the lease term, the Company may purchase the properties or
renew the lease with the lessor's consent or arrange for a sale of the outlets.
During 1996, the Company entered into a similar $100.0 million lease facility
expiring in July 2003.  At December 31, 1996 only one site was leased under the
new facility.  For a description of the company-operated retail outlets, see
"Southwest Marketing" and "Northeast Marketing" in Item 1. Business above.

Allied Businesses segment are the hydrocarbon storage facility at Mont Belvieu,

Belvieu.  See "Southwest Petrochemical and Allied Businesses" in Item 1.
Business above.


ITEM 3.  LEGAL PROCEEDINGS

The Company is engaged in a number of hydrocarbon remediation projects.  While
such cleanup projects are typically conducted under the supervision of a
governmental authority, they do not involve proceedings seeking material
monetary damages from the Company and are not expected to be material to the
Company's operations or financial position.   See Item 1. Business - Regulatory
Matters.

The Company is involved in various claims and lawsuits arising in the normal
course of business.  In the opinion of the Company's management, based upon the
advice of counsel, the ultimate resolution of these matters will not have a
material adverse effect on the Company's financial or competitive position.

(1)    During 1996, the Company changed its presentation of sales and other
       revenues to include Federal excise and state motor vehicle fuel taxes
       collected on the sale of product which were previously reported as a
       reduction of the corresponding tax expense.  Sales and other revenues
       for the four years ended December 31, 1995 has been adjusted to conform
       to the presentation used in 1996.

(2)    On December 14, 1995, Diamond Shamrock acquired National Convenience
       Stores ("NCS"), which operated 661 speciality convenience stores, for a
       net cost of approximately $280.0 million.  The acquisition (the "NCS
       Acquisition") was accounted for using the purchase method of accounting
       and, accordingly, the results of operations of NCS are included from the
       date of acquisition.

(3)    During the second quarter of 1995,  the Company changed its method of
       accounting for refinery maintenance turnaround costs from an accrual
       method to a deferral method.  The change resulted in a cumulative
       adjustment through December 31, 1994 of $22.0 million (after income
       taxes of $13.4 million) or $.31 per share, which is included in net
       income for the year ended December 31, 1995.  The effect of the change
       on the year ended December 31, 1995 was to increase income before
       cumulative effect of accounting change by approximately $3.5 million
       ($.05 per share) and net income by $25.5 million ($.36 per share).  Had
       the change in accounting for refinery maintenance turnaround costs been
       in effect since the beginning of 1992, net income for the years ended
       December 31, 1994, 1993 and 1992 would have been $143.4 million ($2.03
       per share), $115.0 million ($1.65 per share) and $77.0 million ($1.15
       per share), respectively.

(4)    In 1993, Diamond Shamrock changed its method of accounting for certain
       liabilities resulting from an agreement with its former parent.  The
       change resulted in a cumulative adjustment through December 31, 1992 of
       $14.2 million (after income tax benefit of $9.4 million), or $.14 per
       share, which is reflected in net income for the year ended December 31,
       1993.

  (5)  In 1992, Diamond Shamrock changed its method of accounting for
       post-retirement benefits other than pensions and its method of
       accounting for income taxes.  The aggregate cumulative effect of these
       changes as of January 1, 1992 of $17.7 million (after income tax benefit
       of $10.3 million), or $.15 per share, is included in net income for the
       year ended December 31, 1992.

(6)    Historical data for the year ended December 31, 1992 has been adjusted
       to reflect the Company's initial public offering of Common Stock and
       debt and acquisitions of Ultramar Inc. ("UI) and Canadian Ultramar
       Company ("CUC", formerly Canadian Ultramar Limited) in June 1992 as if
       such transactions had been completed on January 1, 1992.

ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
             AND RESULTS OF OPERATIONS

GENERAL

On December 3, 1996, the Company issued 29,876,507 shares of its Common Stock
and 1,725,000 shares of its newly created 5% Cumulative Convertible Preferred
Stock in exchange for all the outstanding Common and 5% Cumulative Convertible
Preferred Stock of Diamond Shamrock, Inc. ("Diamond Shamrock") pursuant to an
Agreement and Plan of Merger dated September 22, 1996.  Common shareholders of
Diamond Shamrock received 1.02 shares of UDS Common Stock for each share of
Diamond Shamrock Common Stock and one share of UDS 5% Cumulative Convertible
Preferred Stock for each share of Diamond Shamrock 5% Cumulative Convertible
Preferred Stock.  The Company also amended its certificate of incorporation to
change its name to Ultramar Diamond Shamrock Corporation.  The Merger was
accounted for using the pooling of interests method.

The Company's operating results are affected by Company-specific factors, such
as its refinery utilization rates and refinery maintenance turnarounds;
seasonal factors, such as the demand for petroleum products and working capital
requirements in the Northeast, both of which vary significantly during the
year; and industry factors, such as movements in and the general level of crude
oil prices, the demand for and prices of refined products and industry supply
capacity.  The effect of crude oil price changes on the Company's operating
results is determined, in part, by the rate at which refined product prices
adjust to reflect such changes.  As a result, the Company's earnings have been
volatile in the past and may be volatile in the future.

During 1995, the Company changed its method of accounting for refinery
maintenance turnaround costs from an accrual method to a deferral and
amortization method to better match revenues and expenses.  The change resulted
in a cumulative adjustment through December 31, 1994 of $22.0 million (after
income taxes of $13.4 million) or $.31 per share, which is included in net
income  for the year ended December 31, 1995.  To facilitate the comparison to
the results of operations for the years ended December 31, 1996 and 1995,
historical data for the year ended December 31, 1994 has been adjusted to
reflect the change in accounting for refinery maintenance turnaround costs as
if the new method had been applied from the inception of the Company.

(1)   On December 14, 1995, the Company acquired NCS, which operated 661
   specialty convenience stores, in a transaction accounted for under the
   purchase method.  Accordingly, the results of operation of NCS are included
   from the date of acquisition.

(2)   During 1996 the Company changed its presentation of sales and other
   revenues to include Federal excise and state motor vehicle fuel taxes
   collected on the sale of product which were previously reported as a
   reduction of the corresponding tax expense.  Sales and other revenues and
   taxes other than

(1)  Effective January 1, 1996, the Company modified its policy for pricing
     refined products transferred from its Quebec refinery to its Northeast
     marketing operations to more closely reflect the spot market prices for
     such refined products.  To facilitate the comparison to the operating data
     for the year ended December 31, 1996, the amounts reported for the year
     ended December 31, 1995 have been adjusted to reflect the pricing policy
     change as if it had occurred on January 1, 1995.  The refining margin and
     retail marketing fuel margin originally reported for the year ended
     December 31, 1995 were $3.42 and 22.9c., respectively.

(2)  Retail marketing fuel margins reported for the Northeast represent a blend
     of gross margin from company and dealer operated service stations, heating
     oil sales and the cardlock business segment.


Net loss for the year ended December 31, 1996 was $35.9 million.  The loss
includes a pre-tax charge of $77.4 million ($53.0 million after taxes) for
transaction and integration costs associated with the Merger on December 3,
1996.  In the Southwest, the loss before income taxes of $23.4 million was
$106.5 million below the income before income taxes and cumulative effect of
accounting change reported in 1995, principally due to increases in operating,
depreciation and interest expense.  Operating expenses include approximately
$50.4 million of one time non-cash charges recorded in the fourth quarter of
1996, primarily to conform accounting practices between Diamond Shamrock and
Ultramar including the accrual of estimated future environmental and other
obligations.  In the Northeast, income before income taxes of $60.6 million was
$3.4 million lower than income before income taxes and cumulative effect of
accounting change reported in 1995.


SOUTHWEST OPERATIONS

Sales and other revenues in the Southwest of $7.2 billion in 1996 were $1.7
billion or 31.8% higher than in 1995 as average product prices increased by
21.7% and product sales volume increased by approximately 13.6% to 416,600 BPD
in 1996. Product


                                       21
   22
and merchandise sales volume increased substantially over 1995, primarily as a
result of the December 1995 acquisition of NCS.  Cost of products sold in 1996
increased, as a percentage of sales, by 4.8% as compared to 1995.

Refining margin at the McKee and Three Rivers Refineries increased by 9.7% to
$3.83 per barrel in 1996, reflecting crude oil price volatility during the
year.  Refining margin at the Wilmington Refinery increased by 6.4% to $4.66
per barrel in 1996 due to an improvement in the heavy, sour crude oil price
differential.  Refinery throughput at the McKee and Three Rivers Refineries
during 1996 increased  by 6.3% to 224,200 BPD as several upgrade and expansion
projects were completed during the year.  Throughput at the Wilmington Refinery
in 1996 increased by 36.8% to 102,700 BPD, principally due to the operation of
the refinery's new gasoil hydrotreater. In addition, refinery throughput at the
Wilmington Refinery in 1995 was adversely affected as refinery units were down
on several occasions to tie in units required to make California Air Resource
Board specification gasoline and to replace the crude oil heater destroyed by a
1995 explosion and fire.  Retail marketing fuel volume increased by 27.9%, to
102,100 BPD, principally as a result of the previously mentioned acquisition of
NCS.  However, fuel margins decreased by 8.0% to 12.7 cents per gallon in 1996,
due to intense competitive pressures.

Merchandise sales at the Company's convenience stores more than doubled from
$1.1 million per day in 1995 to $2.4 million per day in 1996 as the result of
the NCS acquisition.  Merchandise margins for the years 1996 and 1995 remained
relatively constant at 30.6% and 30.0%, respectively.

Refinery operating expenses, before depreciation, of $250.9 million were $23.9
million higher than in 1995, consistent with the increase in refinery
throughput and the commencement of GOH operations at the Wilmington Refinery.
Marketing and other operating expenses of $551.5 million were $225.1 million
higher than in 1995 principally due to the acquisition of NCS and one time non
cash charges recorded in the fourth quarter of 1996 principally to conform
accounting practices between Diamond Shamrock and Ultramar.  Selling, general
and administrative expenses during 1996 of $128.8 million increased by
approximately $39.2 million or 43.8% from 1995, as a result of the acquisition
of NCS.

NORTHEAST OPERATIONS

Sales and other revenues in the Northeast for 1996 of $3.0 billion were 14.9%
higher than in 1995 as average product prices increased by 11.6% and product
sales volume increased by approximately 6.0% to 159,000 BPD in 1996.  Cost of
products sold increased, as a percentage of sales, by 1.7% as compared to 1995.

Refining margins increased 35.2% to $3.15 per barrel in 1996 from $2.33 per
barrel in 1995, as a result of higher average Atlantic Basin crack spreads and
the ability to process lower cost Heidrun crude oil for all of 1996 as compared
to only one month in 1995.  Throughput at the Quebec Refinery averaged 143,900
BPD in 1996 or 6.6% higher than in 1995 as 1995 throughput was adversely
affected by refinery downtime while work was performed to configure the
refinery to run lower cost acidic crude oils such as Heidrun.  Retail fuel
margins decreased 4.7 cents per gallon, or 17.9%, to 21.6 cents from 1995 to
1996, reflecting continued competitive pressures on motorist margins and the
impact of higher distillate wholesale prices on both heating oil and cardlock
sales throughout the first ten months of the year.  Retail marketing sales
volumes for 1996 increased 8.0% from 1995, to 60,900 BPD, as a result of the
Company expanding home heating oil operations and the implementation of the
"value plus" program in the Company's Canadian retail gasoline operations late
in the second quarter of 1996.

Refinery operating expenses, before depreciation, totaled $50.7 million or 96c.
per barrel in 1996 as compared to $46.1 million or 94c. per barrel in 1995.
Refinery operating expenses in 1996 reflect increased throughput as well as the
additive and chemical costs associated with running Heidrun crude oil.
Selling, general and administrative expenses of $173.2 million during 1996 were
$8.1 million higher than in 1995 principally due to the previously mentioned
acquisition of home heating oil and distribution operations in the Northeast
United States during 1996 and the one-time cost related to the roll out of the
"value plus" program.

COMBINED INTEREST AND TAXES

Net interest expense of $110.1 million in 1996 was $30.4 million higher than in
1995 as average borrowings increased from $1.2 billion in 1995 to $1.6 billion
in 1996, primarily as a result of amounts borrowed to finance the acquisition
of NCS.  The average interest rate on the Company's borrowings approximated
8.2% in 1996 and 8.7% in 1995.

The effective income tax rate for 1996 was a 10.7% benefit as compared to a
35.4% expense for 1995.  The decrease in the effective income tax rate was
principally due to nondeductible Merger and other costs recorded in 1996.

(1)   During 1996, the Company changed its presentation of sales and other
      revenues to include Federal excise and state motor vehicle fuel taxes
      collected on the sale of product which were previously reported as a
      reduction of the corresponding tax expense.  Sales and other revenues and
      taxes other than income taxes for the years ended December 31, 1995 and
      1994 reflect the reclassification of such taxes to conform to the
      presentation used in 1996.

(2)   Results of operations for the year ended December 31, 1994, are reported
      on a pro forma basis as if the change in accounting for refinery
      maintenance turnaround costs adopted in 1995 was in effect from the
      inception of the Company.  Historical net income for the year ended
      December 31, 1994 was $136.8 million.

(3)   Certain marketing related costs, originally reported as a reduction of
      sales revenues, have been reclassified to conform with the presentation 
      adopted in 1995.

(1)  Effective January 1, 1996, the Company modified its policy for pricing
     refined products transferred from its Quebec Refinery to its Northeast
     marketing operations to more closely reflect the spot market prices for
     such refined products.  To facilitate the comparison to the operating data
     for the year ended December 31, 1996, the amounts reported for the years
     ended December 31, 1995 and 1994 have been adjusted to reflect the pricing
     policy change as if it had occurred on January 1, 1994.  The refining
     margin and retail marketing fuel margin originally reported for the years
     ended December 31, 1995 and 1994 were $3.42 and 22.9c. and $2.94 and
     26.9c., respectively.

(2)  Retail marketing fuel margins reported for the Northeast represent a blend
     of gross margin from company and dealer operated service stations, heating
     oil sales and the cardlock business segment

(3)  Certain marketing related costs, originally reported as a reduction of
     fuel margin, have been reclassified as selling expenses to conform with
     the 1995 presentation.

Net income before the cumulative effect of the change in accounting for
refinery maintenance turnaround costs totaled $95.0 million in 1995 as compared
to $143.4 million in 1994.  In the Southwest, income before income taxes and
cumulative effect of accounting change for 1995 was $83.1 million or $90.9
million below 1994, principally due to weak refining margins and reduced
refinery throughput.  In the Northeast, income before income taxes and
cumulative effect of accounting change of $64.0 million was $6.6 million higher
than in 1994.

SOUTHWEST OPERATIONS

Sales and other revenues in the Southwest of $5.4 billion in 1995 were $527.4
million or 10.8% higher than 1994 as average product prices increased by 7.4%
and product sales volume increased by approximately 3.9% to 366,700 BPD in
1995.  Cost of products sold in 1995 increased, as a percentage of sales, by
3.8% as compared to 1994.

Refining margin at the McKee and Three Rivers Refineries and the Wilmington
Refinery decreased by 20.7% and 15.3%, respectively, to $3.49 per barrel and
$4.38 per barrel, respectively, from 1994 to 1995 as a result of a narrowing of
the price differential between light and heavy crude oil, increases in overall
Southwest crude oil costs, an oversupply of gasoline during the first half of
1995 attributable to the introduction of Federal specification reformulated
gasoline and, in the case of the Wilmington Refinery, the need to run higher
cost feedstocks following a June 1995 crude oil heater explosion and fire.
Throughput at the McKee and Three Rivers Refineries for 1995 decreased by 8,800
BPD or 4.4%.  Throughput at the Wilmington Refinery decreased by 9,000 BPD or
10.7% as compared to 1994, as refinery units were down on several occasions
during 1995 in order to tie in units required to make California Air Resource
Board specification gasoline and to replace the crude oil heater destroyed by
the previously mentioned explosion and fire.  Retail marketing sales volume
increased by 5,400 BPD, or 7.3%, from 1994 to 1995 as a result of an increase
in retail sites.  However, retail marketing fuel margins decreased by 8.0% from
1994, to 13.8c. per gallon in 1995, partially due to rising wholesale prices
during the second half of 1995.

Merchandise sales and margins at the Company's convenience stores were
comparable from 1994 to 1995, averaging approximately $1.1 million per day and
30.0%, respectively.

Refinery operating expenses, before depreciation, of $227.0 million in 1995
were 3.0% lower than in 1994 while marketing





                                       25
   26
and other operating expenses increased by 29% to $326.4 million due, in part,
to the addition of NCS in December 1995.  Selling, general and administrative
expenses of $89.6 million in 1995 were comparable to those of 1994.


NORTHEAST OPERATIONS

Sales and other revenues in the Northeast for 1995 of $2.7 billion were 5.5%
higher than in 1994 as product sales volume increased by approximately 1.0% to
150,000 BPD and average product prices increased by 8.7% from 1994.  Cost of
products sold, as a percentage of sales, remained relatively consistent from
1994 to 1995.  Refining margins decreased 7.2% to $2.33 per barrel in 1995 from
$2.51 per barrel in 1994, as narrow price differentials between North Sea crude
oil and Gulf Coast based product prices, which began in 1994, continued
throughout most of 1995.  Throughput at the Quebec Refinery decreased by 3.0%
from 1994 levels, to 135,000 BPD in 1995, due to downtime during the second
half of 1995 as work was performed to allow the refinery to run lower cost,
acidic crude oil such as Heidrun.  Retail marketing fuel margins for 1995
averaged 26.3c. per gallon, a decrease of 2.2% from 1994, reflecting  continued
competitive pressures on motorist margins and weak demand for heating oil
caused by mild weather during the first quarter of 1995.  Retail marketing
sales volumes for 1995 were virtually unchanged from 1994 and averaged 56,400
BPD as increased motorist sales volume attributable to the August 1994
acquisition of the Sergaz service station network was offset by the previously
mentioned weak demand for heating oil during the first quarter of 1995.

Refinery operating expenses, before depreciation, totaled $46.1 million or 94c.
per barrel in 1995 as compared to $56.1 million or 93c. per barrel in 1994.
The marginal increase in refinery operating cost per barrel reflects the
reduction in 1995 refinery throughput previously noted.  Refinery operating
expenses in 1994 included the cost of the brief operation and then closure of
the Company's Halifax, Nova Scotia Refinery following the expiration of the
Company's processing agreement with Statoil North America Inc.  Selling,
general and administrative expenses of $165.1 million during 1995 were $14.8
million lower than in 1994 as a result of reduced transportation and other
marketing related costs during 1995 and one-time non-officer employee bonuses
of $2.4 million recorded in 1994.

COMBINED INTEREST AND TAXES

Net interest expense was $79.7 million in 1995 compared to $78.5 million in
1994.  Average borrowing increased from $1.0 billion in 1994 to $1.2 billion in
1995 and the average interest rate on the Company's borrowings approximated
8.7% in both 1995 and 1994.  The impact of increased borrowings was partially
offset by an increase in capitalized interest to $11.0 million in 1995 from
$5.7 million in 1994 as a result of various major capital projects underway in
1995.

The provision for income taxes in 1995 of $52.1 million decreased, as a
percentage of pre-tax income, from 38.0% in 1994 to 35.4% in 1995, principally
as a result of non-taxable income recognized in 1995 from changes in accounting
estimates and the favorable settlement of previously accrued liabilities as
well as certain state income tax credits in the Southwest.


ENVIRONMENTAL MATTERS

The Company's operations are subject to environmental laws and regulations
adopted by various governmental authorities in the jurisdictions in which the
Company operates.  The Company has accrued liabilities for estimated site
restoration costs to be incurred in the future at certain facilities and
properties.  In addition, the Company has accrued liabilities for environmental
remediation obligations at various sites, including the multiparty sites in the
Southwest where the Company has been identified as a potentially responsible
party.  Under the Company's accounting policy, liabilities are recorded when
site restoration and environmental remediation and cleanup obligations are
either known or considered probable and can reasonably be estimated.  At
December 31, 1996 and 1995, accruals for environmental matters amounted to
$151.4 million and $122.2 million, respectively.  Charges to income during 1996
for environmental matters, principally to conform the accounting of Diamond
Shamrock and Ultramar, totaled $41.7 million.  Environmental charges during the
two years ended December 31, 1995 were not significant.

Total future environmental costs cannot be reasonably estimated due to unknown
factors such as the magnitude of possible contamination, the timing and extent
of remediation, the determination of the Company's liability in proportion to
other parties, improvements in clean-up technologies and the extent to which
environmental laws and regulations may change in the future.  Although
environmental costs may have a significant impact on results of operations for
any single period, the Company believes





                                       26
   27
that such costs will not have a material adverse effect on the Company's
operations or financial position.  See Item 1.  "Business--Regulatory
Matters--Environmental" for further discussion of these matters.

CAPITAL EXPENDITURES

The refining and marketing of petroleum products is a capital intensive
business.  Significant capital requirements include expenditures to upgrade or
enhance operating facilities to meet environmental regulations and maintain the
Company's competitive position as well as to acquire, build and maintain
broad-based retail networks.  The capital requirements of the Company's
operations consist primarily of (i) non-discretionary expenditures, such as
those required to maintain reliability and safety and to address environmental
regulations (including reformulated fuel specifications, stationary source
emission standards and underground storage tank regulations); and (ii)
discretionary opportunity expenditures, such as those planned to expand and
upgrade its retail marketing business and to increase the capacity of certain
refinery processing units and pipelines.

During 1996, capital expenditures totaled $343.1 million and included the
completion of a high-pressure gasoil hydrotreater at the Wilmington Refinery
and a heavy gasoil hydrotreater at the Three Rivers Refinery.  The addition of
the gasoil hydrotreaters increases each refinery's ability to upgrade
unfinished product into finished product and to process lower cost, heavy crude
oil and less expensive feedstocks.  Other capital projects included
modifications to the Quebec Refinery to enhance its ability to process acidic
crude oils and modifications to accommodate a unit train to transport product
from the refinery to Montreal.  Capital expenditures also included construction
of a second 730 million pound per year propylene splitter at Mont Belvieu which
was completed in August 1996.

Marketing related capital expenditures in 1996 included construction of new
retail stores, principally in Arizona, and the acquisition of home heating oil
and wholesale distribution operations in the northeast United States.
Additional capital projects included the rebranding and integration of the
acquired NCS stores into the Company's Southwest system.  The rebranding and
integration program included signage on the street and at the service station
pumps and upgraded security, computerization and store interiors.

Although the Company intends to continue to pursue acquisitions and other
capital investment opportunities, the Company's objective is to reduce capital
expenditures on presently operating assets.  Capital expenditures budgeted for
1997 total $285.0 million, a substantial decrease from the Company's four year
annual average through 1996 of $440.0 million.

Over the next five years the Company plans to invest approximately $430.0
million to expand and upgrade its retail and wholesale marketing operations in
the Southwest and Northeast.  The Company plans to expand its retail marketing
presence through the acquisition and construction of approximately 125
company-owned and operated stations with convenience stores.  The current
estimated cost of the Southwest retail growth program for the next several
years is $250.0 million.  In the Northeast, the Company plans to continue a
program begun in 1994 to operate up to 600 of the sites it owns or controls in
its eastern Canadian retail marketing network.  In connection with the program,
the Company intends to invest approximately $100.0 million over the next five
years by adding approximately 400 convenience stores to existing and new
company-operated locations.  In addition, the Company plans to spend
approximately $80 million over the next five years to expand its retail home
heating oil business, primarily through acquisitions in eastern Canada and the
northeastern United States.

The following table sets forth a summary of the growth capital projects planned
by the Company for the next several years at its refineries.  Many of the
projects contain both a non-discretionary component and a discretionary
component intended to take advantage of opportunities to achieve a high return
on investment.  The estimates of the level of expenditures set forth below, are
based upon the Company's current expectations.  It should be noted that
investment plans are subject to change depending on further detailed
engineering and economic studies and that construction costs, which are
particularly difficult to anticipate, could change substantially if the demand
for construction outstrips supply.  The effect of these uncertainties upon the
estimates set forth below could be material and there can be no assurance that
actual costs will not exceed these estimates.

The Company believes that the Quebec provincial government will issue new
refinery liquid effluent regulations during 1998 that, if adopted, will require
modifications and additions to the Quebec Refinery's waste water treatment
facilities.  The Company has completed a detailed process design and estimates
the cost of potential capital expenditures required to comply with the expected
regulations to be approximately $11.6 million.  It is expected that any
required construction for the modifications and new equipment would begin in
1998 and be completed to meet the anticipated new regulations.  See Item 1.
"Business - Regulatory Matters - Environmental-Canadian Operations."

The Company is continually investigating strategic acquisitions and other
business opportunities, some of which may be material, that will complement its
current business activities.

The Company expects to fund its capital expenditures over the next several
years from cash provided by operations and, to the extent necessary, from the
proceeds of borrowings under its bank credit facilities and its commercial
paper and medium-term note programs discussed below.  In addition, depending
upon its future needs and the cost and availability of various financing
alternatives, the Company may, from time to time, seek additional debt or
equity financing in the public or private markets.


LIQUIDITY AND CAPITAL RESOURCES

The Company had a cash position of $197.9 million at December 31, 1996.
Following the Merger, the Company negotiated new committed, unsecured bank
facilities which provide a maximum of $500.0 million of available credit to the
Company (the "U.S. Facility") and Cdn. $200.0 million of available credit to
Canadian Ultramar Company ("CUC", formerly Canadian Ultramar Limited).  In
addition, the Company has a $200.0 million commercial paper program supported
by the U.S.  Facility.  The bank facilities extend through 2001 and reflect a
reduction in interest rates compared to the facilities they replaced.  The
Company's bank facilities and certain of its other debt instruments require the
maintenance of certain financial ratios and contain covenants that must be
complied with to maintain borrowing privileges.  The Company believes these
covenants will not have a significant impact on the Company's liquidity and
ability to borrow funds as needed.  At December 31, 1996, the Company had
approximately $574.2 million of borrowing capacity under the bank facilities
and commercial paper program and approximately $240.0 million of borrowing
capacity under uncommitted short-term lines of credit with a number of
financial institutions.





                                       28
   29
The Company also has the ability to issue an additional $50.0 million of medium
term notes under a $200.0 million shelf registration filed with the Security
and Exchange Commission in August 1994.

In 1996, the Company entered into a long-term lease agreement (the "Jamestown
Lease") to accommodate its retail outlet construction program.  Pursuant to the
terms of the lease, the lessor has agreed to finance the acquisition and/or
construction  of retail marketing sites up to $100.0 million and to lease these
sit`es to the Company.  After the non-cancelable lease term, which expires in
July 2003, the Jamestown Lease may be extended by agreement of the parties, or
the Company may purchase or arrange for the sale of the retail outlets.
Substantially all of the $100.0 million commitment is presently available to
the Company.

The Company believes its current sources of funds will be sufficient to satisfy
its capital expenditure, working capital, debt service and dividend
requirements for at least the next twelve months.

In February 1997, the Company's Board of Directors declared a Common Stock
dividend of $.275 per share payable on March 7, 1997, to holders of record on
February 20, 1997.  In addition, the Board of Directors declared a quarterly
dividend of $.625 per share on its 5% Cumulative Convertible Preferred Stock,
payable on March 14, 1997, to holders of record on February 20, 1997.


Cash Flow

Net cash provided by operating activities, consisting principally of net (loss)
income adjusted for depreciation and amortization, provisions for losses on
receivables, changes in deferred income taxes and changes in working capital
accounts, amounted to $293.6 million, $245.5 million and $329.2 million in the
years ended December 31, 1996, 1995 and 1994, respectively.

Net cash used in investing activities amounted to $308.2 million, $636.6
million and $356.5 million in the years ended December 31, 1996, 1995 and 1994,
respectively.  Investment activities consist principally of refining and
marketing capital expenditures and acquisitions, net of the proceeds of asset
disposals in the ordinary course of business and, beginning in 1995, deferred
refinery maintenance turnaround costs.

Net cash provided by financing activities in the year ended December 31, 1996
amounted to $37.8 million.  In June 1996, Diamond Shamrock issued $100.0
million of 7.65% debentures due in July 2026.  In addition, the Company had
borrowings under its various bank credit facilities and commercial paper
program aggregating $478.9 million during the year ended December 31, 1996.
During 1996 the Company repaid $490.5 million of long-term debt consisting of
$275.7 million of scheduled debt maturities and $214.8 million under its
various bank credit facilities.  Other financing activity in 1996 included
$14.0 million of proceeds received principally from the exercise of employee
stock options and dividend reinvestment, $5.2 million received from Diamond
Shamrock's ESOPs and from the sale of treasury stock and the payment of $69.8
million in Preferred and Common Stock dividends.  For the year ended December
31, 1995, net cash provided by financing activities totaled $483.6 million
including $128.0 million of proceeds from a secondary offering of the Company's
Common Stock and the exercise of employee stock options and dividend
reinvestment and $790.0 million of proceeds from long-term borrowings including
$224.2 million of medium-term notes, $100.0 million of 7.25% and 8.75%
debentures and $465.8 million of borrowings under its various credit
facilities.  During 1995, the Company repaid $375.9 million of long-term debt
consisting of $33.9 million of scheduled debt maturities and $342.0 million
under its credit facilities.  The Company also received $6.1 million from its
ESOPs and the sale of treasury stock and made Preferred and Common Stock
dividend payments of $64.6 million during 1995.  Financing activities in the
year ended December 31, 1994 did not result in a change in the Company's net
cash position as the proceeds of long-term borrowings and the exercise of
employee stock options and dividend reinvestment were offset by the repayment
of short and other long-term debt and the payment of Preferred and Common Stock
dividends.

The effect of changes in currency exchange rates on the Company's net cash
position during the three year period ended December 31, 1996 was not material.

Income Taxes

At December 31, 1996, the Company had deferred tax assets of $276.4 million and
$27.4 million and deferred tax liabilities of $294.0 million and $66.8 million
from its U.S. and Canadian operations, respectively.

Current accounting standards require, among other things, recognition of future
tax benefits measured by enacted tax rates attributable to deductible temporary
differences between financial statement and income tax bases of assets and
liabilities and net operating loss carryforwards, to the extent that the
realization of such benefits is more likely to occur than not.  The realization
of the deferred tax assets is dependent on the Company's ability to generate
taxable income in both the U.S. and Canada.  Management has determined, based
on the Company's history of operating earnings and its expectations for the
future, that it is more likely than not that the deferred tax assets will be
realized.  See Notes to Consolidated Financial Statements - Note 13: Income
Taxes.


OUTLOOK

The Company's earnings depend largely on refining and retail marketing margins.
The petroleum refining and marketing industry has been and continues to be
volatile and highly competitive.  The cost of crude oil purchased by the
Company as well as the price of refined products sold by the Company have
fluctuated widely in the past.  As a result of the historic volatility of
refining and marketing margins and the fact that they are affected by numerous
diverse factors, it is impossible to predict future margin levels.

In general, industry inventories are lower than they were a year ago. This
should bode well for the industry as we enter the driving season.  In addition,
backwardation has moderated in the crude oil market and crude oil prices have
been declining and are relatively stable at present.  Although, we believe 1997
crude oil spreads will be improved over 1996, we do not expect a secular
improvement in the industry in the near term.

California refining margins have improved in early 1997 due in part to
persistent refinery problems experienced by some competitors and scheduled
turnarounds in the industry.  The retail margins, although improving, remain
weak because of the very competitive West Coast market.

Early in the first quarter, the refining margins in Texas remain weak due to
the fall in product prices.  If product prices stabilize, refining margins
should improve as the refineries run the lower cost crude.  Retail margins in
Texas and surrounding states are weak and remain flat from the fourth quarter.

In eastern Canada, refining spreads have weakened while retail margins have
strengthened because of strong heating oil retail prices.


DERIVATIVE FINANCIAL INSTRUMENTS

The Company uses interest rate swaps and forward contracts, foreign exchange
contracts and commodity futures, forward and option contracts to manage its
exposure to interest rate, exchange rate and commodity price volatility.  The
Company controls its derivative positions based on their underlying principal
values and does not transact derivative positions that exceed the Company's
underlying business exposure.  The Company does not use complex, leveraged
derivative transactions with the intent of producing speculative gains.  See
Notes to Consolidated Financial Statements - Note 16: Financial Instruments.





                                       30
   31
SEASONALITY

In the Northeast, demand for petroleum products varies significantly during the
year.  Distillate demand during the first and fourth quarters can range from
30% to 40% above the average demand during the second and third quarters.  The
substantial increase in demand for heating oil during the winter months results
in the Company having significantly higher accounts receivable and inventory
levels during the first and last quarters of each year.  The Company's
Southwest operations are less affected by seasonal fluctuations in demand than
its operations in the Northeast.  The working capital requirements of the
Southwest operations are limited, due to lower inventory requirements and show
little fluctuation throughout the year.


EXCHANGE RATES

The exchange rate between the Canadian and U.S. dollar has weakened
substantially from the inception of the Company in 1992.  The rate, however,
has remained relatively constant during the three year period ended December
31, 1996 as well as during the first two months of 1997.  The Company expects
the exchange rate to fluctuate during 1997 but cannot reasonably predict its
future movement.

As the Company's Canadian operation is in a net asset position, the weaker
Canadian dollar has reduced, in U.S. dollars, the Company's net equity at
December 31, 1996 by $58.3 million.  With the exception of its crude oil costs,
which are U.S. dollar denominated, the weaker Canadian dollar has also had the
effect of reducing, in U.S. dollars, the revenues and the related costs and
expenses reported by the Company's Canadian operation.  The potential impact on
refining margins of fluctuating exchange rates together with U.S. dollar
denominated crude oil costs is mitigated by the Company's pricing policies in
Canada, which generally pass on any change in the cost of crude oil.  Marketing
margins, on the other hand, have been adversely affected by exchange rate
fluctuation, as competitive pressures have, from time to time, limited the
Company's ability to promptly pass on the increased costs to the ultimate
consumer.

The Company periodically enters into short-term foreign exchange contracts to
manage its exposure to the negative effects of exchange rate fluctuations on
the trade payables of its Canadian operation that are denominated in U.S.
dollars.  The Company generally does not hedge the effects of foreign exchange
rate fluctuations on the translation of its foreign results of operations or
financial position.  However, the Company has considered various hedge
alternatives available to it, along with their attendant costs, and expects to
hedge the translation impact when such hedging is considered economically
appropriate.


IMPACT OF INFLATION

Although inflation has slowed in recent years, it is still a factor in the U.S.
and Canadian  economies, increasing the cost to acquire or replace property,
plant and equipment and increasing the costs of supplies and labor.  As
previously noted, to the extent permitted by competition, the Company passes
along increased costs to its customers.

In addition, the Company is affected by volatility in the cost of crude oils
and refined petroleum products as market conditions continue to be the primary
factor in determining the costs of the Company's products.  The Company uses
the LIFO method of accounting for its inventories.  Under this method, the cost
of products sold reported in the financial statements approximates current cost
and thus reduces distortion in reported income.

                     ULTRAMAR DIAMOND SHAMROCK CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1: ORGANIZATION

Ultramar Diamond Shamrock Corporation (the "Company" or "UDS", formerly
Ultramar Corporation or "Ultramar") is a Delaware  company with crude oil
refining and petroleum product marketing operations in the southwest United
States (the "Southwest") and northeast United States and eastern Canada (the
"Northeast").  The Company markets petroleum products (principally
transportation fuels and heating oil) through both wholesale and retail
distribution facilities and a broad range of convenience items through
company-operated stores in all its market areas.

Under the terms of an Agreement and Plan of Merger dated September 22, 1996
between the Company and Diamond Shamrock, Inc. ("Diamond Shamrock"), Diamond
Shamrock was merged with and into the Company effective December 3, 1996, in a
transaction accounted for as a pooling-of-interests (the "Merger") (see Note
3).  In connection with the Merger, the Company changed its name from Ultramar
Corporation to Ultramar Diamond Shamrock Corporation.


NOTE 2:  SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation.  The consolidated financial statements include the
accounts of the Company and its wholly-owned subsidiaries.  All financial
information includes the results of Diamond Shamrock for all periods presented
prior to the Merger on December 3, 1996 (see Note 3).  Investments in 50% or
less owned companies are accounted for using the equity method of accounting.
Certain 1995 and 1994 amounts have been reclassified to conform to the
presentation used in 1996.


Use of estimates:  The preparation of financial statements in accordance with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the amounts reported in the financial statements
and accompanying notes.  Actual results could differ from those estimates.

Cash and Cash Equivalents.  The Company considers all highly liquid investments
with a maturity of three months or less when purchased to be cash equivalents.

Inventories.  Crude oil and refined and other finished product inventories are
valued at the lower of cost or market (net realizable value).  Cost is
determined primarily on the last-in, first-out ("LIFO") basis.  Materials and
supplies and convenience store items are valued at average cost, not in excess
of market value.

Property, Plant and Equipment.  Property, plant and equipment are recorded at
cost.  Depreciation is provided on the straight-line method over the estimated
useful lives of depreciable assets.

Environmental Costs.  Environmental costs are expensed if they relate to an
existing condition caused by past operations and do not contribute to future
revenue generation.  Liabilities are recorded when site restoration and
environmental remediation and cleanup obligations are either known or
considered probable and can be reasonably estimated.  Recoveries of
environmental costs through insurance, indemnification arrangements or other
sources are reported separately as receivables to the extent such recoveries
are considered probable.

Excise Taxes.  Federal excise and state motor vehicle fuel taxes collected on
the sale of products and remitted to governmental agencies are included in
sales and other revenues and taxes other than income taxes.  Such amounts
totaled $2.0 billion, $1.8 billion and $1.7 billion for the years ended
December 31, 1996, 1995 and 1994, respectively.

Income Taxes.  Income taxes include deferred taxes resulting from temporary
differences in the bases of assets and liabilities for financial and tax
reporting purposes.  The liability method of accounting for income taxes
requires the effect of tax rate changes on current and accumulated deferred
income taxes to be reflected in the period in which the rate change was
enacted.

Functional Currency.  The functional currency of the Company's Canadian
operations is the Canadian dollar.  The translation into U.S. dollars is
performed for balance sheet accounts using exchange rates in effect at the
balance sheet date and for revenue and expense accounts using the weighted
average exchange rate during the year.  Adjustments resulting from such
translation are recorded as a separate component of stockholders' equity.

Earnings per share.  The computation of primary earnings (loss) per common
share is based on the weighted average number of





                                       38
   39
common shares outstanding during the year and, to the extent dilutive, common
stock equivalents consisting of stock options, stock awards subject to
restrictions and stock appreciation rights.  Primary earnings (loss) per common
share have been adjusted for dividend requirements on Preferred Stock.  The
computation of fully diluted earnings per share assumes conversion of the
Preferred Stock during the time that the shares are outstanding if such
conversion is dilutive.


NOTE 3: MERGER OF ULTRAMAR AND DIAMOND SHAMROCK

On December 3, 1996, Diamond Shamrock merged with and into the Company.  In
connection with the Merger, the Company issued 29.876 million shares of its
Common Stock and 1.725 million shares of its newly created 5% Cumulative
Convertible Preferred Stock in exchange for all the outstanding Common Stock
and 5% Cumulative Convertible Preferred Stock of Diamond Shamrock.  The
shareholders of Diamond Shamrock received 1.02 shares of UDS Common Stock for
each share of Diamond Shamrock Common Stock and one share of UDS 5% Cumulative
Convertible Preferred Stock for each share of Diamond Shamrock 5% Cumulative
Convertible Preferred Stock.  The Merger qualified as a tax-free reorganization
and was accounted for as a pooling-of-interests.  Accordingly, the Company's
consolidated financial statements have been restated for all periods prior to
the Merger to include the results of operations, financial position and cash
flows of Ultramar and Diamond Shamrock.

Sales and other revenues, net loss (income) and dividends per share for
Ultramar and Diamond Shamrock for the periods prior to the Merger are presented
below.  Since the Merger was effective December 3, 1996, the table reflects the
sales and other revenues and net loss for the entire year of 1996.  Operations
from December 3, 1996 to year-end would not have a material impact on the data
presented.

In combining the financial information of Ultramar and Diamond Shamrock,
certain reclassifications of historical financial data have been made to
conform the accounting policies of the two companies.  Reclassifications
include the presentation of Ultramar Federal excise and state motor vehicle
fuel taxes collected on the sale of product as sales and other revenues with a
corresponding charge to taxes other than income taxes.  In addition, Diamond
Shamrock interest income has been reclassified from sales and other revenues to
interest income.

In connection with the Merger, the Company recorded merger and integration
costs of $77.4 million ($53.0 million net of income tax benefits) during the
fourth quarter of 1996.  Merger costs of $13.1 million consist principally of
financial and legal fees and registration costs.  Integration costs of $64.3

completed by the end of 1997.  Additional costs, if any, will be recognized in

taken to combine the two companies.


NOTE 4:  ACQUISITION OF NATIONAL CONVENIENCE STORES

On December 14, 1995, Diamond Shamrock completed the acquisition of National
Convenience Stores Incorporated ("NCS").  NCS operated 661 "Stop N Go"
convenience stores located in Texas.  The total value of the transaction,
including transaction costs and the assumption of debt, was approximately
$280.0 million.  The acquisition has been accounted for using the purchase
method of accounting and, accordingly, the operating results of NCS have been
included in the consolidated operating results since the date of acquisition.
The purchase price exceeded the fair value of net assets acquired by
approximately $160.5 million, which is included in the accompanying
consolidated balance sheet as an intangible asset (see Note 9).

The pro forma financial data below, which combines the results of operations of
the Company and NCS prior to the acquisition, are unaudited and reflect
purchase price accounting adjustments assuming the acquisition had occurred at
the beginning of each year presented.

NOTE 5:  CHANGE IN ACCOUNTING FOR REFINERY MAINTENANCE TURNAROUND COSTS

During the second quarter of 1995, Ultramar changed its method of accounting
for refinery maintenance turnaround costs from an accrual method to a deferral
and amortization method to better match revenues and expenses.  The change
resulted in a cumulative adjustment through December 31, 1994 of $22.0 million
(after income taxes of $13.4 million) or $.31 per share, which is included in
net income for the year ended December 31, 1995.  The effect of the change on
the year ended December 31, 1995 was to increase income before cumulative
effect of accounting change by approximately $3.5 million ($.05 per share) and
net income by $25.5 million ($.36 per share).  Pro forma net income for the
year ended December 31, 1994 of $143.4 million ($2.03 per share), reflects the
effect of the retroactive application of the change in accounting for refinery
maintenance turnaround costs  as if the new method had been applied since the
inception of the Company.

Between 1987 and 1989, Diamond Shamrock placed 9% Senior Notes due 1987 - 1997,
8.35% Senior Notes due 1989 - 1997 and 8.77% Senior Notes due 1997 - 2009 with
an institutional investor and loaned the proceeds to two Employee Stock
Ownership Plans (see Note 11).  The 8.77% notes require annual installment
payments of $3.2 million in 1997 and $4.1 million through 2009.  Senior Notes
also include 10.75% notes which require annual installment payments of $30.0
million through April 1999.  Since the Company intends to refinance the
scheduled payments by the use of other credit facilities which would be
classified as long-term, and the Company has the ability to do so, the annual
installments due in 1997 have been classified as long-term.

The Company issued the 8.25% Notes due in 1999 and Ultramar Credit Corporation
("UCC"), a financing subsidiary, issued the 8.625% Guaranteed Notes due in
2002, in public offerings in 1992.  The 8.625% Guaranteed Notes issued by UCC
are guaranteed by the Company.  Both of these notes are unsecured and interest
is payable semi-annually.

Medium term notes at December 31, 1996 consisted of $150.0 million of 8% notes
due in 2005, $75.0 million of 9.375% notes due in 2002 and $70.0 million of
notes with an average interest rate of 7.8% and an average maturity of 12
years.  The medium-term notes are unsecured and interest is payable
semi-annually.

At December 31, 1996, the Company's committed bank facilities consisted of (i)
a U.S. facility under which the Company may borrow and obtain letters of credit
in an aggregate amount of $500.0 million (the "U.S. Bank Facility") and (ii) a
Canadian facility under which the Company's Canadian subsidiary, Canadian
Ultramar Company ("CUC", formerly Canadian Ultramar Limited), may borrow, issue
bankers acceptances and obtain letters of credit in an aggregate amount of Cdn.
$200.0 million (the "Canadian Bank Facility" and together with the U.S. Bank
Facility, the "Bank Facilities").  The Company must pay annual fees of 1/9 of
1% on the total used and unused portion of the Bank Facilities.  The interest
rates under the Bank Facilities are floating, based upon the prime rate, the
London interbank offered rate or other floating interest rates, at the option
of the Company.  At December 31, 1996, there were no borrowings drawn against
the Company's Bank Facilities.  Amounts outstanding under the Bank Facilities
are due in 2001, upon expiration of the facilities.

The Bank Facilities and the indentures governing the various notes contain
restrictive covenants relating to the Company and its financial condition,
operations and properties.  Under these covenants, the Company and certain of
its subsidiaries are required to, among other things, maintain consolidated
interest coverage and debt-to-total capital ratios.  Although these covenants
have the effect of limiting the Company's ability to pay dividends, it is not
anticipated that such limitations will affect the Company's present ability to
pay dividends.  At December 31, 1996, under the most restrictive of these
covenants, $273.2 million was available for the payment of dividends.

Diamond Shamrock issued $100.0 million of 7.65% debentures due in 2026, $25.0
million of non-callable 7.25% debentures due in 2010, $75.0 million of
non-callable 8.75% debentures due in 2015 and $100.0 million of 8.0% debentures
due in 2023.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED


The Company has a $200.0 million commercial paper program supported by the U.S.
Bank Facility.  At December 31, 1996, borrowings under the commercial paper
program of $146.0 million were classified as long-term based on the Company's
ability and intent to refinance these amounts on a long-term basis, using its
Bank Facilities.

At December 31, 1996, the Company had available money market lines of credit
with numerous financial institutions which provided the Company with additional
uncommitted borrowing capacity of $375.0 million and Cdn.$198.7 million.
Borrowings under the money market lines are typically short-term and bear
interest at prevailing market rates as established by the financial
institutions.  At December 31, 1996 and 1995, outstanding borrowings were
$280.0 million at a weighted average interest rate of 6.23% and $163.0 million
at a weighted average interest rate of 6.05%, respectively.  Since the Company
has the ability and intent to refinance the scheduled maturities by the use of
the Bank Facilities, borrowings under the money market lines have been
classified as long-term.

Diamond Shamrock assumed mortgages with a net present value of $59.3 million
(the "Mortgages") as part of the NCS acquisition in December 1995.  The
Mortgages currently carry an annual interest rate of 9.5%, have maturities of 6
years and are recorded at their net present value of $44.6 million.  The
Mortgages are secured by retail properties owned by the Company.

The aggregate maturities of long-term debt at December 31, 1996 were as
follows:


                                                                                                         (in millions)

Outstanding letters of credit totaled $79.4 million and $17.4 million at
December 31, 1996 and 1995, respectively.

The Company has the ability to issue an additional $50.0 million of medium-term
notes under a $200.0 million shelf registration filed with the Securities and
Exchange Commission in August 1994.

Interest payments totaled $114.0 million (net of capitalized interest of $8.8
million), $85.8 million (net of capitalized interest of $11.0 million) and
$80.8 million (net of capitalized interest of $5.7 million) for the years ended
December 31, 1996, 1995 and 1994, respectively.


NOTE 11:     STOCKHOLDERS' EQUITY

At December 31, 1996, the Company had issued and outstanding 1.725 million
shares of 5% Cumulative Convertible Preferred Stock.  The Preferred Stock is
non-voting and holders of Preferred Stock are entitled to receive a quarterly
dividend of $.625 per share which must be paid before a dividend can be paid on
the Company's Common Stock.  The Preferred Stock has a liquidation value of
$50.00 per share (aggregate liquidation value of $86.3 million) and each
Preferred Share can be converted into the number of shares of the Company's
Common Stock obtained by dividing $50.00 by the conversion price then in effect
($25.98 at December 31, 1996), at any time up to and including the redemption
date.  Until June 14, 2000, the Preferred Stock is redeemable at the option of
the Company for Common Stock, subject to certain conditions precedent relating
to the market price of the Common Stock.  After June 15, 2000, it is redeemable
for cash at the option of the Company, at a redemption price of $50 per share
plus any accrued and unpaid dividends.

In October 1995, the Company issued 5.75 million shares of Common Stock in a
public offering at an offering price of $22.875 per share.  Net proceeds to the
Company were approximately $125.5 million.

The Company has adopted several Long-Term Incentive Plans (the "LTIPs"), which
are administered by the Compensation Committee of the Board of Directors.
Under the terms of the LTIPs, the Board may grant restricted stock, stock
options, stock appreciation rights, performance units and securities awards to
officers and key employees of the Company.  The vesting period

for awards under the LTIPs are established by the Board at the time of grant.
Restricted shares awarded under the Company's 1992 and 1996 LTIPs generally
vest on the third anniversary of the date of grant. Restricted shares granted
under the Company's 1987 and 1990 LTIPs vest over a three year period through
1999.  Stock options may not be granted at less than the fair market value of
the Company's Common Stock at the date of grant and may not expire more than
ten years from the date of grant.  Options granted by Diamond Shamrock prior to
the Merger become exercisable 40%, 30% and 30% on the first, second and third
anniversaries of the date of grant.  Under the terms of Ultramar's 1992 LTIP,
upon the occurrence of a change in control, all rights and options become
immediately vested and exercisable, and all restricted shares immediately vest.
As a result, upon consummation of the Merger, 1,152,920 options became
exercisable and 24,898 restricted shares vested.

Grants of restricted shares and performance units under the 1987 and 1990 LTIPs
for 1996, 1995 and 1994, as adjusted to reflect the Merger, are summarized as
follows:

The Company recognized compensation expense during 1996, 1995 and 1994 related
to the performance units of $2.9 million, $1.6 million and $0.5 million,
respectively.

On December 19, 1996 and February 19, 1997, the Compensation Committee granted
2,949,250 and 106,450 stock options, respectively, under the 1996 LTIP.  Under
these grants, 1,100,700 shares vest 30%, 30% and 40% on the first, second and
third anniversaries of the date of grant and 1,955,000 shares vest 100% after 
4 1/2 years, except that accelerated vesting will occur if the market price of
the Company's Common Stock reaches prescribed levels prior to such time.  These
stock options have terms ranging from 5 to 10 years.  A total of 2,945,550
shares are available for future issuance under the 1996 LTIP.

Stock option transactions under the various LTIPs are summarized below.  The
exercise price and number of stock options issued in transactions under the
1987 and 1990 LTIPs occurring prior to December 3, 1996, the effective date of
the Merger, have been adjusted to reflect the exchange of 1.02 shares of UDS
Common Stock for each share of Diamond Shamrock Common Stock.

The Company applies Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees" and related interpretations in accounting for its
stock option plans as allowed under Statement of Financial Accounting Standards
No. 123, "Accounting for Stock-Based Compensation".  Accordingly, the Company
has not recognized compensation expense for its stock options granted.  Had
compensation expense for the Company's stock options granted in 1996 and 1995
been determined based on the fair value at the grant dates consistent with the
methodology of Statement No. 123, pro forma net (loss) income applicable to
common shares and net (loss) income per common share would have been as
follows:



                                                                           Year Ended December 31,

The weighted average fair value of options granted during the years ended
December 31, 1996 and 1995 was $5.83 and $6.54, respectively.  Because
Statement No. 123 is applicable only to options granted in fiscal years
beginning subsequent to December 15, 1994, its pro forma effect will not be
fully reflected until 1997.

For purposes of the pro forma disclosures, the estimated fair value of options
is amortized to expense over the options' vesting period.  The fair value for
these options was estimated at the respective grant dates using a Black-Scholes
option pricing model with the following weighted-average assumptions:

In January 1993, the Board of Directors adopted the Ultramar Corporation Annual
Incentive Plan ("AIP") which provides for cash and restricted Common Stock
awards to officers and certain key employees of the Company.  Annual awards
under the AIP are generally based on attainment of various performance measures
established by the Company's Board of Directors.  Restricted shares awarded
under the terms of the AIP generally vest on the second anniversary of the date
of grant.  A total of 446,363 shares remain available for issuance under the
AIP.

A Performance Incentive Plan has been adopted by Diamond Shamrock under which
the Compensation Committee may grant cash awards to eligible employees.  For
the years 1996, 1995 and 1994, the Company paid $4.3 million, $2.4 million and
$2.7 million, respectively, under this plan.

Prior to the Merger, Diamond Shamrock had established two Employee Stock
Ownership Plans ("ESOP").  ESOP I was formed in





                                       46

                     ULTRAMAR DIAMOND SHAMROCK CORPORATION
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED


June 1987, and ESOP II was formed in April 1989.  All employees of Diamond
Shamrock who have attained a minimum length of service and satisfy other plan
requirements are eligible to participate in the ESOPs except that ESOP II
excludes employees covered by any collective bargaining agreements.

Prior to 1993, Diamond Shamrock loaned the ESOPs $65.8 million to purchase
shares of the Company's Common Stock and contributed 82,400 treasury shares of
its Common Stock to ESOP I as part of special award and success sharing
programs.  In accordance with the success sharing program, the Company accrued
and expensed $1.5 million and $2.8 million for the purchase of 55,523 shares
and 107,681 shares in 1995 and 1994, respectively.  There were no purchases of
shares in 1996 and the success sharing program was terminated prior to the
effective date of the Merger.  A total of 2,776,300 shares are available for
future issuance under the plans.

The Company will make contributions to the ESOPs in sufficient amounts, when
combined with dividends on the Common Stock, to retire the principal and to pay
interest on the loans used to fund the ESOPs.  Common shares will be allocated
to participants and included in the computation of earnings per share as the
payments of principal and interest are made on the loans.  Contributions to the
ESOPs that were charged to expense for 1996, 1995 and 1994 were $5.6 million,
$7.5 million and $7.4 million, respectively.  Dividend and interest income
reduced  the amounts charged to expense in 1996, 1995 and 1994 by $1.7 million,
$1.5 million and $1.8 million, respectively.

At December 31, 1996, there were 1,968,653 allocated shares and 94,824 suspense
shares held by the ESOPs.

Under the terms of the Company's Restricted Share Plan for Directors, directors
who were not officers of the Company received an award of 400 shares of
restricted Common Stock of the Company for each year of their term as director.
In 1996, the annual award level under the plan was increased to 600 shares.
The director's restricted shares vested on the last day of the term for which
such shares were awarded or upon the occurrence of a change in control.  At
December 31, 1996, 19,000 restricted shares were awarded and, as a result of
the Merger, were fully vested.  A total of 31,000 shares are available for
future issuance under the plan.

In December 1993, the Board of Directors adopted the Ultramar Corporation Stock
Purchase and Dividend Reinvestment Plan which allows eligible holders of the
Company's Common Stock to use dividends to purchase Company stock and to make
optional cash payments to buy additional shares of Common Stock.  The Company
has reserved a total of 2,000,000 shares of Common Stock for issuance under
this plan.  At December 31, 1996, a total of 6,722 shares had been issued under
the plan and 1,993,278 shares remain available for future issuance.

On February 5, 1997, the Board of Directors declared a quarterly dividend of
$.275 per common share, payable on March 7, 1997 to holders of record on
February 20, 1997.  In addition, the Board of Directors declared a quarterly
dividend of $.625 per share on the Company's 5% Cumulative Convertible
Preferred Stock, payable on March 14, 1997, to holders of record on February
20, 1997.


NOTE 12:     BENEFIT PLANS

The Company has several qualified, non-contributory defined benefit pension
plans (the "Qualified Pension Plans") covering substantially all of its
salaried employees in the United States, other than those subject to collective
bargaining agreements.  These plans generally provide retirement benefits based
on years of service and compensation during specified periods.  Senior
executives and certain key employees covered by these plans are also entitled
to participate in various unfunded supplemental executive retirement plans
which provide retirement benefits based on years of service and compensation,
including compensation not permitted to be taken into account under the
Qualified Pension Plans (the "Supplemental Pension Plans" and together with the
Qualified Pension Plans, the "Pension Plans").

Under the Qualified Pension Plans, the Company's policy is to fund normal cost
plus the amortization of the unfunded actuarial liability for costs arising
from qualifying service determined under the projected unit credit method.  The
underlying pension plan assets include cash equivalents, fixed income
securities (primarily obligations of the United States government) and equity
securities.

The Company also maintains a retirement plan for Diamond Shamrock's collective
bargaining groups (the "Bargaining Unit Plan").  The Bargaining Unit Plan
generally provides benefits that are based on the union member's monthly base
pay during the five years before retirement.

As a result of the Merger, the Company assumed obligations with respect to a
retirement plan for the former non-employee Directors of Diamond Shamrock (the
"Directors Retirement Plan").  The Directors Retirement Plan provides an annual
retirement benefit for

a period of time equal to the shorter of (a) length of service as a
non-employee Director or (b) life of Director.  Following the Merger, the
Company discontinued future contributions to the Directors Retirement Plan.

Benefit plan expense related to the Company's Pension Plans was as follows:

The assumptions used to measure the projected benefit obligations under the
Company's Pension Plans at December 31, 1996 and 1995 were as follows: assumed
discount rate -- 7.50% for 1996 and 7.25% for 1995 and assumed rate for
compensation increases, including increases for promotions -- 4.0% - 4.75% for
1996 and 4.0% - 4.50% in 1995.  The weighted average expected long-term rate of
return on plan assets used to determine net periodic pension cost for each of
the three years in the period ended December 31, 1996 was 9%.

The Company also maintains several defined contribution retirement plans for
substantially all its eligible employees in the United States and Canada.
Contributions to the plans are generally determined as a percentage of each
eligible employee's salary.  The aggregate costs of these plans amounted to
$8.0 million, $5.6 million and $6.0 million during the years ended December 31,
1996, 1995 and 1994, respectively.

The Company sponsors unfunded defined benefit postretirement plans which
provided health care and life insurance benefits to retirees who satisfy
certain age and service requirements.  In addition, pursuant to the terms of a
distribution agreement between Diamond Shamrock and Maxus, Diamond Shamrock's
parent company prior to its 1987 spin-off, the Company also shares in the cost
of providing similar benefits to former employees of Maxus (see Note 15).

Generally, the health care plans pay a stated percentage of most medical
expenses reduced for any deductibles, payments made by government programs and
other group coverage.  The cost of providing most of these benefits is shared
with retirees.

Net periodic postretirement benefit costs included the following components:



                                                                       Years Ended December 31,

The principal assumptions used in the computation of net periodic
postretirement benefit cost and the accumulated benefit obligation were as
follows: weighted average assumed discount rate -- 7.5% for 1996 and 7.25% for
1995; rate of increase in future compensation levels -- 4.0% - 4.75% for 1996
and 4.0% - 4.5% for 1995.  The health care cost trend rate for the U.S. ranged
from 7.8% to 11.5% in 1996 and was assumed to decrease gradually to 6.0% - 6.5%
by the year 2001 and remain at that level thereafter.  The rate in 1995 ranged
from 9.2% to 12.25%.  In Canada, the rate was 8.0% in 1996 and 8.25% in 1995.
The 8.0% rate was assumed to decrease gradually to 5.25% by 2000 and to remain
at that level thereafter.  Increasing the assumed weighted average health care
cost trend rate by 1% in each year would increase the accumulated
postretirement benefit obligation under the U.S. and Canadian plans as of
December 31, 1996 by $5.4 million and $1.0 million, respectively, and the
aggregate of the service and interest cost components of net periodic
postretirement benefit cost for the year then ended by $0.9 million and $0.1
million, respectively.

Deferred income taxes arise from temporary differences between the tax basis of
assets and liabilities and their reported amounts in the financial statements.
The components of the Company's deferred income tax liabilities and assets

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED


The realization of deferred tax assets recorded at December 31, 1996 is
dependent on the Company's ability to generate future taxable income in both
the U.S. and Canada.  Although realization is not assured, the Company believes
it is more likely than not that the deferred tax assets will be realized.

The difference between the Company's effective income tax rate and the U.S.
Federal statutory rate is reconciled below:

At December 31, 1996, the Company had U.S. Federal and state income tax credit
carryforwards totaling $30.8 million which will expire in the years 2002
through 2010, and Federal and state alternative minimum tax credits totaling
$31.5 million which can be carried forward indefinitely.  In addition, at
December 31, 1996, the Company had U.S. net operating loss carryforwards for
income tax purposes amounting to $194.1 million which will expire in the years
1998 through 2011.

Income taxes paid in the years ended December 31, 1996, 1995 and 1994 amounted
to $9.6 million, $19.0 million and $15.1 million, respectively.


NOTE 14:    ENVIRONMENTAL MATTERS

The Company's operations are subject to environmental laws and regulations
adopted by various governmental authorities in the jurisdictions in which the
Company operates.  Accordingly, the Company has adopted policies, practices and
procedures in the areas of pollution control, product safety, occupational
health and the production, handling, storage, use and disposal of hazardous
materials to prevent material environmental or other damage, and the material
financial liability which could result from such events.  However, some risk of
environmental or other damage is inherent in the business of the Company, as it
is with other companies engaged in similar businesses.

The Company has been designated as a potentially responsible party by the U.S.
Environmental Protection Agency (the "EPA") under the Comprehensive
Environmental Response, Compensation, and Liability Act of 1980, and by certain
states under applicable state laws, with respect to the cleanup of hazardous
substances at several sites.  In each instance, other potentially responsible
parties also have been so designated.  In addition, the Quebec Ministry of
Environment and Montreal Urban Community are investigating possible instances
of contamination at two of the Company's Canadian facilities.  The Company has
agreed to remediate certain of these sites and is currently assessing other
sites.  The Company has accrued liabilities for environmental remediation
obligations at these sites, as well as estimated site restoration costs to be
incurred in the future.

At December 31, 1996 and 1995, accruals for environmental matters amounted to
$151.4 million and $122.2 million, respectively (included principally in "Other
long-term liabilities").  Charges to income during 1996 for environmental
matters, principally to conform the accounting policies of Diamond Shamrock and
Ultramar, totaled $41.7 million.  Charges to income during the two year period
ended December 31, 1995 for environmental matters were not significant.

The accruals noted above represent the Company's best estimate of the costs
which will be incurred over an extended period of

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED


time for restoration and environmental remediation at various sites.  These
liabilities have not been reduced by possible recoveries from third parties and
projected cash expenditures have not been discounted.  Total future
environmental costs cannot be reasonably estimated due to unknown factors such
as the magnitude of possible contamination, the timing and extent of
remediation, the determination of the Company's liability in proportion to
other parties, improvements in cleanup technologies and the extent to which
environmental laws and regulations may change in the future.  Although
environmental costs may have a significant impact on results of operations for
any single period, the Company believes that such costs will not have a
material adverse effect on the Company's financial position.


NOTE 15:   COMMITMENTS AND CONTINGENCIES

The Company leases gasoline stations, office space and other assets under
operating leases with terms expiring at various dates through 2017.  Certain
leases contain renewal options and escalation clauses and require the Company
to pay property taxes, insurance and maintenance costs.  These provisions vary
by lease.  Certain gasoline station leases provide for the payment of rentals
based solely on sales volume while others provide for payments, in addition to
any established minimums, contingent upon the achievement of specified levels
of sales volumes.

Future minimum rental payments applicable to noncancellable operating leases at
December 31, 1996 are as follows:




                                                                                             (in millions)

The Company has two long-term lease arrangements (the "Brazos Lease" and the
"Jamestown Lease") to accommodate its retail outlet construction program. The
Brazos and Jamestown Leases have lease terms which will expire in December and
July 2003, respectively.  At December 31, 1996, substantially all of the $190.0
million Brazos Lease commitment had been used to construct or purchase retail
outlets and substantially all of the $100.0 million Jamestown Lease commitment
remained available to construct or purchase retail outlets.  After their
non-cancelable lease term, the Brazos and Jamestown Leases may be extended by
agreement of the parties, or the Company may purchase or arrange for the sale
of the retail outlets.  If the Company were unable to extend the lease or
arrange for the sale of the properties under the Brazos Lease to a third party
in 2003, the amount necessary to purchase

the properties under lease as of December 31, 1996 would be approximately
$190.0 million.

At December 31, 1996, the Company had several ocean-going tankers and coastal
vessels under various noncancellable time charters which expire on various
dates through 1998.  Certain charters include renewal options and escalation
clauses, which vary by charter.  Certain charters provide for the payment of
chartering fees which vary based on usage.  Aggregate future minimum payments
required under the time charters total $18.9 million for 1997 and $12.9 million
for 1998.  Charges to income for marine freight time charters amounted to $54.4
million, $54.7 million and $64.3 million for the years ended December 31, 1996,
1995 and 1994, respectively.

In conjunction with the construction of a high-pressure gasoil hydrotreater at
the Company's Wilmington Refinery, the Company entered into a long-term
contract for the supply of hydrogen.  The contract commenced in 1996 and will
run for 15 years.  The purchase price for the hydrogen is fixed, based on the
quantity and flow rate of product supplied.  The contract has a take-or-pay
provision of $1.2 million per month.  In November, 1996, the Company also
entered into a contract for the supply of hydrogen to its Three Rivers
Refinery, containing a take-or-pay provision of $0.7 million per month, with an
initial term of 15 years.

Pursuant to the terms of various agreements, the Company has agreed to
indemnify the former owner of Ultramar Inc.  ("UI") and CUC and certain of its
affiliates for any claims or liabilities arising out of, among other things,
refining and marketing activities and litigation related to the operations of
UI and CUC prior to their acquisition.  The Company has also agreed to
indemnify two affiliates of the former owner against liability for
substantially all U.S. Federal, state and local income or franchise taxes in
respect of periods in which any UI company was a member of a consolidated,
combined or unitary return with any other member of the affiliated group.

In connection with the 1987 spin-off of Diamond Shamrock from Maxus, Diamond
Shamrock entered into a distribution agreement which, among other things,
provided for the sharing by the Company and Maxus of certain liabilities
relating to businesses Maxus discontinued or disposed of prior to the spin-off
date.  The Company's total liability for such shared costs was limited to $85.0
million.  The Company has fully performed all of its obligations to Maxus under
the agreement as of December 31, 1996, including $8.3 million paid during 1996.

There are various legal proceedings and claims pending against the Company
which arise in the ordinary course of business.  It is management's opinion,
based upon advice of counsel, that these matters, individually or in the
aggregate, will not have a material adverse effect on the Company's results of
operations or financial condition.

stated at cost, which approximates fair market value.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED


The aggregate carrying amounts of notes receivable approximated fair value as
determined based on the discounted cash flow method.

The fair value of the Company's fixed rate debt at December 31, 1996 and 1995
was $1,288.3 million and $1,305.1 million, respectively (carrying amounts of
$1,219.9 million and $1,180.6 million, respectively) and was estimated based on
the quoted market price of similar debt instruments.  The carrying amounts of
the Company's borrowings under its revolving credit agreements and bank money
market facilities approximate fair value because such obligations generally
bear interest at floating rates.

In 1996, the Company entered into interest rate swap agreements the effect of
which is to modify the interest rate characteristics of a portion of its debt,
from fixed to floating rate.  At December 31, 1996, the Company had two
contracts with notional principal amounts of $100.0 million each that expire in
2002 and 2005.  Under the terms of the contracts, the Company and a major
financial institution agree to pay, on a semi-annual basis, the differential
between using a fixed interest rate and a weighted average of LIBOR rates, as
stipulated in the contracts.  Amounts to be paid or received under the
contracts are recorded as an adjustment to interest expense.  The notional
principal amounts of the contracts represent the extent of the Company's
involvement in these transactions but do not represent its exposure to market
risk.  The Company is subject to market risk as interest rates fluctuate and
impact the interest payments due on the notional principal amounts.  The fair
value of interest rate swap contracts is determined based on the difference
between the contract rate of interest and the rates currently quoted for
contracts of similar terms and maturities.

The Company uses futures, forward and option contracts to reduce its exposure
to crude oil  and petroleum product  price volatility and does not use such
contracts with the intent of producing speculative gains.  These contracts
permit settlement by the delivery or receipt of the related crude oil and
petroleum products.  The contracts are marked to market value and gains and
losses are recognized currently, in the caption cost of products sold, as a
component of the related crude oil and petroleum product purchases.  At
December 31, 1996, the Company had outstanding futures contracts to purchase
$51.4 million and sell $22.9 million of crude oil and petroleum products which
mature on various dates through May 1997.  At December 31, 1995, the Company
had outstanding futures contracts to purchase $30.7 million and to sell $27.6
million  of crude oil and petroleum products, which matured on various dates
through March 1996.  The Company is subject to the risks associated with
changes in the value of the underlying crude oil and petroleum products;
however, such changes in values are generally offset by changes in the sales
price of the Company's petroleum products.  The carrying and fair value of
commodity futures is based on quoted market values.

The Company also periodically enters into short-term foreign exchange contracts
to manage its exposure to exchange rate fluctuations on the trade payables of
its Canadian operation that are denominated in U.S. dollars.  These contracts
involve the exchange of Canadian and U.S. currency at future dates.  Gains and
losses on these contracts generally offset  losses and gains on the U.S. dollar
denominated  trade payables.  At December 31, 1996, the Company had short- term
foreign exchange contracts totaling $10.8 million.  The Company had no foreign
exchange contracts at December 31, 1995.  The notional amount of the contracts
represents the extent of the Company's involvement in these transactions but
does not represent its exposure to market risk.  The fair value of short-term
foreign exchange contracts is determined based on year-end exchange rates. The
Company generally does not hedge for the effects of foreign exchange rate
fluctuations on the translation of its foreign results of operations or
financial position.

The Company is exposed to credit risk in the event of nonperformance by the
counterparties to its interest rate, foreign exchange rate and petroleum
related forward and option contracts but does not anticipate nonperformance by
any of these counterparties.  The amount of such exposure is generally the
unrealized gains on such contracts.  Other financial instruments which
potentially subject the Company to credit risk consist principally of temporary
cash investments and trade receivables.  The Company places its temporary cash
investments with high credit quality financial institutions and, by policy,
limits the amount of credit exposure with any one financial institution.
Concentrations of credit risk with respect to trade receivables are limited due
to the large number of customers comprising the Company's customer base and
their dispersion across different geographic areas.  As of December 31, 1996,
the Company had no significant concentrations of credit risk.

The results for the fourth quarter of 1996 include $77.4 million of Merger and
integration costs and $50.4 million of charges principally to conform the
accounting practices of Diamond Shamrock, Inc. and Ultramar Corporation,
including the accrual of estimated future environmental and other obligations.
In addition, as a result of a decision to increase certain inventory levels
during the fourth quarter of 1996, the Company recorded an additional LIFO
inventory reserve of $60.7 million as a result of higher than expected crude
oil prices.

During the third quarter of 1996, Ultramar Corporation changed its presentation
of sales and other revenues to include Federal excise and state motor vehicle
fuel taxes collected on the sale of product which were previously reported as a
reduction of the corresponding tax expense.  The effect of the change in
presentation was to increase previously reported sales and other revenues for
the first through fourth quarters of 1995 and the first and second quarter of
1996 by $238.2 million, $269.6 million, $283.7 million, $277.0 million, $275.2
million and $287.3 million, respectively.

The results for the first quarter of 1995 have been restated to reflect a
change in the accounting for refinery maintenance turnaround costs from an
accrual method to a deferral method adopted in the second quarter of 1995.  The
effect of the change on the first quarter was to increase income before the
cumulative effect of accounting change by approximately $1.7 million and to
increase net income by approximately $23.7 million.
