                                  NEWS RELEASE


         TOREADOR REPORTS SIGNIFICANT IMPROVEMENT IN FIRST-QUARTER 2003
                         RESULTS, IN LINE WITH FORECAST

    EARNINGS PER SHARE INCREASE TO $0.07; REVENUES CLIMB 88% TO $6.4 MILLION

         DALLAS, TEXAS - (MAY 21, 2003) - Toreador Resources Corporation
(NASDAQ: TRGL; TSE: TRX) today reports significantly improved first-quarter 2003
financial results, with income applicable to common shares of $704,000, or $0.07
per diluted share, compared with a loss applicable to common shares of $1.9
million, or $0.21 per diluted share, for the first quarter of 2002. Operating
income for the first quarter of 2003 climbed to $1.6 million, compared with an
operating loss of $1.9 million for the same period last year. First-quarter 2003
revenues rose 88% to $6.4 million from $3.4 million for the year-ago quarter.
First-quarter 2003 results are within the ranges forecasted by Toreador earlier
this year.

         Higher oil and gas prices, lower general and administrative expenses,
and more favorable oil and gas hedging arrangements accounted for the noteworthy
improvement in first-quarter 2003 results compared with the year-ago period. In
addition, the company continued to reduce long-term debt.

         "With the Madison Oil Company acquisition fully and successfully
integrated, we believe first-quarter results more appropriately reflect a normal
operating environment for Toreador," said G. Thomas Graves III, President and
Chief Executive Officer of Toreador. "Our operating environment also has
improved with the advent of higher commodity prices. We plan to continue to
aggressively reduce G&A costs, which were down 20% for the quarter compared with
the year-ago period, while focusing on a near-term exploration program,
primarily in Turkey. We are prepared to move forward with a firm growth strategy
in place."

         The company expects to strengthen its balance sheet by continuing to
reduce debt and increasing stockholders' equity, according to Graves. In
addition, management continues to review alternatives to refinance all or part
of Toreador's capital structure. The company is analyzing financing options that
would increase working capital, which could include the possible sale of its
French properties.

         During the first quarter of 2003, Toreador's oil and gas production was
252,000 barrels of oil equivalent (BOE), a 15% decrease from first-quarter 2002
production of 296,000 BOE. Lower volumes were offset by higher commodity prices
in the quarter. The company's first-quarter 2003 average realized price per BOE
rose 72% to $30.99 from $17.99 per BOE for the first quarter of 2002.

         For the first quarter of 2003, 46% of oil and gas production on a BOE
basis was hedged at an average ceiling price per BOE of approximately $28.00.
Higher first-quarter revenues were partially

offset by a loss related to oil and gas production hedges of $1.3 million.
Revenues for the first quarter of 2002 included a loss related to hedges of $2.1
million.

         In 2003, the company has hedged approximately 75% of its natural-gas
production at about $5.00 per thousand cubic feet (Mcf). In addition, Toreador
has hedged approximately 50% of its international oil production at a $26.00 per
barrel ceiling based on Brent crude pricing. None of its domestic oil is hedged.

         "With more than 50% of our estimated 2003 production free from hedges,
this year we should be able to continue to participate in higher commodity
pricing," said Graves. "Despite the first-quarter hedging loss, we expect
stronger commodity prices to have a positive impact on results. Hedges currently
in place are primarily to satisfy credit-facility requirements."

EARNINGS GUIDANCE

         In an effort to provide investors with more meaningful guidance
regarding future financial results, Toreador's management has established the
following policy: Forecasts of periodic quarterly or full-year results will be
provided, affirmed, updated or rescinded when the company deems it prudent and
feasible to do so.

OPERATIONS BRIEF

TURKEY

         Toreador's exploration focus in 2003 will be the Thrace Basin and Sinop
areas of western and northern Turkey. The low-cost program, which is estimated
to range from $1.0-$1.5 million, is expected to include the drilling of shallow
wells and a well re-entry.

         As previously reported, Toreador plans to complete the Barbaros-1 well
in the Thrace Basin gas play west of Istanbul. Based on well-log evaluation,
Toreador estimates the Barbaros-1 could produce at an initial rate of 2 million
cubic feet of gas per day. Depending on test results of the Barbaros-1, the
company could drill an appraisal well to confirm the discovery and proceed with
project development.

         In addition, Toreador plans to drill three low-cost, high-potential
exploration wells on the Gallipoli Peninsula in the Thrace Basin, 40 miles
southwest of Barbaros-1, to follow up on gas shows encountered by other
operators. Toreador holds working interests in six Thrace Basin licenses ranging
from 25%-100% and operates four of them. Toreador's partner, PEMI, operates the
remaining two licenses.

         In the Sinop area northeast of Ankara, the company plans to re-enter a
well that encountered numerous oil and gas shows when it was drilled by another
operator in the late 1980s. Toreador operates and holds a 100% working interest
in six Sinop permits.

         In the shallow-water western Black Sea, Toreador has identified at
least six gas prospects with per-prospect reserve potential ranging from 200
billion cubic feet to 1 trillion cubic feet. The reserve potential estimate is
the result of a 2D seismic survey completed on four contiguous permits in 2002.
The company anticipates selecting two well locations, with drilling targeted to
begin by early 2004. Toreador

is operator and holds a 49% working interest in eight Black Sea permits. The
Turkish national oil company, TPAO, holds the remaining interest.

         In the Cendere Field in south central Turkey, Toreador's development
program continues. As previously disclosed, it is anticipated that a 3D seismic
survey of the field in mid-2003 will delineate the northeastern portion and help
the company identify additional drilling locations on the structure. The Cendere
Field, in which Toreador holds a 19.6% working interest, is operated by TPAO and
producing at a gross rate of 2,100 barrels of oil per day (BOPD) (about 400 BOPD
net).

         The Zeynel Field, 15 miles to the southwest of Cendere, is producing at
a gross rate of 625 BOPD (50 BOPD net). Upcoming work in the field includes
re-entering the Zeynel-6 development well to test the deeper Derdere formation.
Toreador has an 8.5% royalty interest in the Zeynel Field, which is operated by
Aladdin Middle East.

         In late 2002, the East Hasancik-1 well, a new-field wildcat on the
Zeynel permit, discovered oil on a previously untested structure. The East
Hasancik-1 well is on long-term test and will be deepened to the primary
objectives of the Karababa and Derdere formations. Toreador has a 6.75% royalty
interest in the East Hasancik-1 well, located west-southwest of the Zeynel Field
on the Zeynel permit. The well operator is Aladdin Middle East.

FRANCE

         Current production continues at a rate of about 1,200 BOPD from
Toreador's five 100%-owned and operated oil fields in France.

         The company has expanded its international acreage position in France
with the recent government award of two permits for an initial four-year
exploration period. The Nemours and Aufferville permits cover a total of about
80,000 acres 20 miles northwest of the company's Courtenay exploration permit.
Toreador has identified deeper Jurassic Dogger leads on the Nemours and
Aufferville acreage; the Triassic formation also is prospective in this area.

         In late 2002, the French government awarded Toreador the 183,000-acre
Courtenay permit for an initial four-year exploration period. The company's
analysis to date indicates the Neocomian producing trend could continue in an
east-northeast direction onto this permit. In 2003, Toreador will analyze
previously acquired seismic data and gather geological information.

         As previously announced, if 2003 capital allocation permits, Toreador
plans to implement a development program that will include the drilling of six
development wells and six workover wells in the Neocomian complex to further
exploit this highly productive area.

ROMANIA

         Toreador may expand its Romanian acreage holdings later this year in a
bid round for 37 blocks offered by the government for future development,
including secondary recovery. The company is analyzing the blocks' potential
and, depending on its findings, could participate in the bid round to be held
during the second half of 2003. It is anticipated the Romanian government will
award blocks by year-end.

         As previously announced, in early 2003 the Romanian government awarded
Toreador the 324,000-acre Viperesti Block in exchange for a staged work
commitment. Toreador is 100% owner and operator of the block. During a five-year
exploration period, Toreador plans to acquire and assimilate geological and
geophysical data, analyze seismic information and re-enter one of several
previously drilled wells on the block. Subsequently, Toreador could drill one or
more exploration wells.

TRINIDAD

         Toreador is in the process of trading its 11.28% working interest in
Trinidad's Southwest Peninsula Block for an override in the block. As previously
disclosed, Toreador has determined not to participate in future exploration on
the block, which is operated by Trinidad Exploration and Development, Ltd.

UNITED STATES

         In the first quarter of 2003, Toreador continued to earn significant
revenues from its U.S. oil and gas perpetual-fee mineral and royalty interest
portfolio, representing $2.2 million, or 35% of total revenues.

         Mineral and royalty interest revenues provide a solid financial
foundation on which Toreador continues to build its worldwide exploration and
development program. Less than 5% of the more than 1.4 million net acres in the
company's U.S. mineral portfolio are leased or producing, which provides
potential for additional future revenues from the remaining unleased acreage.
The wells on Toreador's mineral holdings are drilled and completed by various
operators at no cost or risk to the company.

         Toreador continues to participate in the completion, including flow
testing, of the Walton Gas Unit 2-2 well located on the 1,000-acre Walton Gas
Unit prospect. Part of the larger Bethel Dome Project in Anderson County in East
Texas, the exploratory well has been drilled to a total depth of 10,100 feet and
producing casing set to total depth. Toreador has a 5.86% interest in the well
and any subsequent offset development-well locations.

         In West Texas, the company owns a 16.6% working interest in 6,000 gross
acres where one well has been successfully completed in the San Andres formation
and a second well is being completed, also in the San Andres.
