ITEM 1. BUSINESS

GENERAL

Petroleum Helicopters, Inc. (the "Company" or "PHI"), a Louisiana corporation,
was incorporated as a Delaware corporation in 1949. Since its inception, the
Company's primary business has been to transport personnel and, to a lesser
extent, parts and equipment, to, from, and among offshore platforms for
customers engaged in the oil and gas exploration, development, and production
industry. Today, the Company maintains its position as the largest provider of
helicopter transportation services in the Gulf of Mexico ("the Gulf"), providing
approximately 47% of all the contracted aircraft in the Gulf. PHI also provides
helicopter services internationally and to non-oil and gas customers such as
emergency medical service providers and governmental agencies. The Company's
Technical Services Unit provides maintenance and repair services to helicopter
airframes and engines and sells helicopter repair parts. The Company currently
operates 279 aircraft domestically and internationally.

On March 10, 2000, the Company's pilots voted to become organized under the
Office and Professional Employees International Union (OPEIU). On February 21,
2001, the National Mediation Board (NMB) declared that all practical methods for
adjusting the dispute between PHI and the OPEIU have been exhausted without
effecting a settlement. See "Employees" within this "Item 1. Business" and
"Union Job Action" within "Item 7. Management's Decision and Analysis of
Financial Condition and Results of Operations".

Beginning in late 2000, certain actions were taken in an effort to restore the
profitability of the Company. Included in those actions were a reduction in the
work force announced in December 2000, and implemented in February 2001, which
primarily affected Lafayette support operations; and closure of operations in
Thailand and China, as well as fixed wing operations in Lafayette, which
consisted of four fixed wing aircraft. The Company also initiated discussions to
exit its ownership position in Clintondale Aviation, Inc. with operations
primarily in Kazakhstan. Further, the Company is in the process of restructuring
its maintenance operations at its main facility in Lafayette, Louisiana. The
Company anticipates that it will take several months for the cost structure to
reflect these actions. The Company also sold several of its nonessential
aircraft subsequent to year end and has executed contracts for the sale of
certain other aircraft. The Company also has plans for sales of other identified
aircraft over the next several months.

DESCRIPTION OF OPERATIONS

PHI is a leading provider of helicopter services to the offshore oil and gas
industry and to other customers such as emergency medical providers and
governmental agencies. The Company operates under a variety of contractual
arrangements to perform services that include transporting passengers and
equipment, operating customer-owned aircraft, leasing aircraft to certain
customers, consulting, and the repair and maintenance of helicopters.
Domestically, oil and gas aviation revenues are earned in


                                       1
<PAGE>   4

federal and state waters offshore of the States of Louisiana, Texas, Alabama,
Mississippi, and California. The Company's international operations are
currently conducted in Angola, Antarctica, Brazil, China, Kazakhstan, Mexico,
Russia (Sakhalin Island), Saudi Arabia, Taiwan, and Democratic Republic of
Congo. Aeromedical operations are currently conducted in Arizona, Arkansas,
California, Colorado, Florida, Illinois, Kentucky, Louisiana, Michigan,
Mississippi, North Dakota, Ohio, South Carolina, and Wisconsin. For financial
information regarding the Company's operating segments and the geographic areas
in which they operate, see Note 10 of the Notes to Consolidated Financial
Statements included elsewhere in this Annual Report.

DOMESTIC OIL AND GAS AND OTHER. PHI operates approximately 200 aircraft related
to its Domestic Oil and Gas operations from several bases or heliports in the
Gulf of Mexico region and one base in California. Operating revenues from the
Domestic Oil and Gas and Other segment accounted for 64%, 62%, 64%, and 69% of
consolidated operating revenues during the year ended December 31, 2000, the
eight months ended December 31, 1999, and the years ended April 30, 1999 and
April 30, 1998, respectively.

PHI's Oil and Gas operations primarily transport its customers' workers and
equipment to platforms and other offshore locations. Oil and gas exploration and
production companies and other offshore oil service companies use PHI's services
for routine offshore transportation and also to evacuate personnel during
medical and safety emergencies and during the threat of hurricanes and other
adverse weather conditions. Most of the aircraft are available for hire by any
customer. However, some are dedicated to individual customers. The Company
operates helicopters that have flying ranges of up to 450 miles and thus, are
capable of servicing many of the deepwater oil and gas operations that are 50 to
250 miles offshore.

The Domestic Oil and Gas and Other segment also includes certain non-oil and gas
related operations including activities related to forest fire-fighting for
certain government agencies.

While routine and minor maintenance and repairs are performed at the various
Domestic Oil and Gas base locations, certain major overhauls and maintenance and
repairs of a larger scope are performed at PHI's Lafayette, Louisiana facility.
In 2001, the Company will move to a new leased facility in Lafayette enabling
the Company to consolidate its Lafayette operations.

INTERNATIONAL. PHI also provides helicopter services in Latin America, Africa,
Eastern Europe, Asia, and Antarctica. The Company operates approximately 30
aircraft internationally. Each aircraft operating internationally is typically
dedicated to one customer. The Company's international customers are mostly oil
and gas customers, including some that are national oil companies and some that
are based in the U. S. However, some international services are also provided to
certain foreign governmental entities and certain U. S. governmental agencies.
Operating revenues from the Company's International segment accounted for 9% of
consolidated operating revenues during the year ended December 31, 2000, and 10%
during each of the eight months ended December 31, 1999, and the years ended
April 30, 1999 and April 30, 1998.

AEROMEDICAL. The Company also provides air medical transportation services for
hospitals and medical programs in several states and currently operates
approximately 45 aircraft within its Aeromedical segment. The aircraft dedicated
to this segment are specially outfitted to accommodate emergency patients and
related emergency medical equipment. The Aeromedical segment's operating
revenues accounted for 19%, 21%, 19%, and 15% of consolidated operating revenues
during the year ended December 31, 2000, the eight months ended December 31,
1999, and the years ended April 30, 1999 and April 30, 1998, respectively.

The Company's Air Evac Services, Inc. subsidiary operates 10 aircraft in Arizona
and offers its aeromedical services to many hospitals and medical programs. Each
of the other aircraft operated by the Aeromedical segment are typically
dedicated to one hospital or medical program.

TECHNICAL SERVICES. PHI performs maintenance and repair services at its
Lafayette facility for a variety of helicopter owners. The Technical Services
segment's capabilities include the maintenance and overhaul of helicopter
airframes, engines, and components. This segment also sells repair parts. The
Technical Services segment has an experienced staff that performs a range of
maintenance tasks under an FAA-approved repair station license. The license
includes authority to repair airframes, powerplants, accessories, radios, and
instruments and to perform specialized services. PHI Technical Services is also
an authorized service center for Bell Helicopter Textron, Inc., American
Eurocopter Corporation, and Turbomeca Engine Corporation, and has extensive
experience and capabilities in Sikorsky Aircraft Corporation S-76 maintenance
and repair. Operating revenues from the Technical Services segment accounted for
7% of consolidated operating revenues during each of the year ended December 31,
2000, the eight months ended December 31, 1999, and the year ended April 30,
1999 and 6% for the year ended April 30, 1998.


                                       2
<PAGE>   5

WEATHER AND SEASONAL ASPECTS

Poor visibility, high winds, and heavy precipitation can affect the safe use of
helicopters and result in a reduced number of flight hours. A significant
portion of the Company's operating revenues is dependent on actual flight hours
and a substantial portion of the Company's direct costs is fixed. Thus,
prolonged periods of adverse weather can materially and adversely affect the
Company's operating revenues and net earnings. In the Gulf of Mexico, the months
of December through February have more days of adverse weather conditions than
the other months of the year. Also in the Gulf of Mexico, June through November
is tropical storm season. When a tropical storm is about to enter the Gulf of
Mexico or begins developing, flight activity may increase because of evacuations
of offshore workers. However, during tropical storms, PHI is unable to operate
offshore.

Additionally, the fall and winter months have fewer hours of daylight.
Consequently, flight hours are generally lower at these times, which typically
result in a reduction in operating revenues during those months. The Company
currently operates seventy-nine aircraft equipped to fly pursuant to instrument
flight rules ("IFR") in the Gulf, which enables these aircraft, when manned by
IFR rated pilots and co-pilots, to operate at times when poor visibility
prevents flights by aircraft that can fly only by visual flight rules ("VFR").
Poor visibility is the most common of the adverse weather conditions that
affects the Company's operations.

INVENTORY

For aircraft maintenance and repair related to PHI helicopters and those
repaired by the Technical Services segment, the Company carries an inventory of
aircraft parts. Many of these inventory items are parts that have been removed
from an aircraft, reworked to a useable condition, and returned to inventory.
The Company uses systematic valuation procedures to estimate the costs of these
used parts. As a result, the costs and carrying values of inventory reported in
the Company's financial statements are impacted by these estimates.

RISKS AND UNCERTAINTIES OF FOREIGN OPERATIONS

Operations in foreign countries generally are subject to various risks attendant
to doing business outside the United States. This may include risks of war,
general strikes, civil disturbances, currency fluctuations and devaluations and
governmental activities that may limit or disrupt markets, restrict payments or
the movement of funds, or result in the deprivation of contract rights or the
taking of property without fair compensation. No prediction can be made as to
what foreign governmental regulations may be enacted in the future that could be
applicable to helicopter operations.

SAFETY AND INSURANCE

The operation of helicopters inherently involves a degree of risk. Hazards, such
as aircraft accidents, collisions, fire, and adverse weather, are inherent in
the business of providing helicopter services and may result in losses of
equipment and revenues. The Company's safety record is very favorable in
comparison to the record for all United States operators as reflected in
industry publications.

The Company is subject to the federal Occupational Safety and Health Act
("OSHA") and similar state statutes. The Company has an extensive safety and
health program. The primary functions of the safety staff are to develop Company
policies that meet or exceed the safety standards set by OSHA, train Company
personnel, and make daily inspections of safety procedures to ensure their
compliance with Company policies on safety. Personnel are required to attend
safety training meetings at which the importance of full compliance with safety
procedures is emphasized. The Company believes that it meets or exceeds all OSHA
requirements and that its operations do not expose its employees to unusual
health hazards.

The Company maintains hull and liability insurance on its aircraft, which
generally insures the Company against physical loss of, or damage to, its
aircraft and against certain legal liabilities to others. In addition, the
Company carries war risk, expropriation, confiscation, and nationalization
insurance for its aircraft involved in international operations. In some
instances, the Company is covered by indemnity agreements from oil companies,
hospitals, and medical programs in lieu of, or in addition to, its insurance.
The Company's aircraft are not insured for loss of use. While the Company
believes it is adequately covered by insurance and indemnification arrangements,
the loss, expropriation or confiscation of, or severe damage to, a material
number of its helicopters could adversely affect revenues and profits.


                                       3
<PAGE>   6

GOVERNMENT REGULATION

As a commercial operator of helicopters, the Company's flight and maintenance
operations are subject to regulation by the Federal Aviation Administration (the
"FAA") pursuant to the Federal Aviation Act of 1958 (the "Federal Aviation Act",
as amended). The FAA has authority to exercise jurisdiction over personnel,
aircraft, ground facilities, and other aspects of the Company's business.

The Company transports personnel and property in its helicopters pursuant to an
Air Taxi Certificate granted by the FAA under Part 135 of the Federal Aviation
Regulations. This certificate contains operating specifications that allow the
Company to conduct its present operations but is subject to amendment,
suspension, and revocation in accordance with procedures set forth in the
Federal Aviation Act. The Company is not required to file tariffs showing rates,
fares, and other charges with the FAA. The FAA's regulations, as currently in
effect, also require that at least 75% of the Company's voting securities be
owned or controlled by citizens of the United States or one of its possessions,
and that the president and at least two-thirds of the directors of the Company
be United States citizens. The Company's president and all of its directors are
United States citizens, and its organizational documents provide for the
automatic reduction in voting power of each share of voting common stock owned
or controlled by a non-United States citizen if necessary to comply with these
regulations.

The National Transportation Safety Board (the "NTSB") is authorized to
investigate aircraft accidents and to recommend improved safety standards.

The Company is also subject to the Communications Act of 1934 because of its
ownership and operation of a radio communications flight following network
throughout the Gulf of Mexico and off the coast of California.

Numerous federal statutes and rules regulate the offshore operations of the
Company and the Company's customers, pursuant to which the federal government
has the ability to suspend, curtail, or modify certain or all offshore
operations. A suspension or substantial curtailment of offshore oil and gas
operations for any prolonged period would have an immediate and materially
adverse effect on the Company. A substantial modification of current offshore
operations could adversely affect the economics of such operations and result in
reduced demand for helicopter services.

COMPETITION

The Company's business is highly competitive in each of its markets. Many of the
Company's contracts are awarded after competitive bidding. The principal aspects
of competition are safety, price, reliability, availability, and service.

The Company is the largest operator of helicopters in the Gulf of Mexico. There
are two major and several small competitors operating in the Gulf market.
Certain of the Company's customers and potential customers in the oil industry
operate their own helicopter fleets; however, oil companies traditionally
contract for most specialty services associated with offshore operations,
including helicopter services. Competition in the air medical market continues
to increase.

The Technical Services segment competes regionally and nationally against
various small and large repair centers in the United States and Canada.
Competition has intensified with aggressive pricing and acquisition moves by
several service providers and original equipment manufacturers and their
subsidiaries.

EMPLOYEES

As of December 31, 2000, the Company employed a total of 1,939 people. As of
March 14, 2001, the Company reduced the number of its employees to 1,784 as part
of its restructuring as discussed in Item 7 - Management's Discussion and
Analysis of Financial Condition and Results of Operations.

On March 10, 2000, the Company's pilots voted to become represented by the
Office and Professional Employees International Union. On February 21, 2001, the
National Mediation Board declared that all practical methods for adjusting the
dispute between PHI and the OPEIU have been exhausted without affecting a
settlement. The NMB released both parties from the mediation process, thereby
starting a 30-day cooling off period, which ended at 11:01 p.m. CST March 23,
2001. At this point, the union is free to engage in job actions, including work
stoppages, and the Company is free to do whatever is reasonable necessary to
continue safe operations. As of March 29, 2001, the Company is unable to predict
with any certainty what will happen after this cooling-off period.

AIRCRAFT MAINTENANCE & REPAIR

Because of safety concerns and federal regulations, the Company is required to
perform regular inspections and perform maintenance, overhauls, and repairs to
its aircraft in accordance with strict guidelines imposed by FAA, NTSB, and the
Company itself. The Company incurs significant costs to perform these
maintenance, overhauls, and repairs.

CUSTOMERS

The Company's principal customers are major and independent exploration and
production companies. The Company also serves oil and gas service companies,
hospitals and medical programs, government agencies, and other aircraft owners
and operators. The Company's largest customer, a Domestic Oil and Gas customer,
accounted for 12%, 13%, 17%, and 16% of operating revenues for the year ended
December 31, 2000, the eight months ended December 31, 1999, and the years ended
April 30, 1999, and 1998, respectively. The Company's five largest customers
accounted for approximately 35% of operating revenues in each of the last four
fiscal periods.

ENVIRONMENTAL MATTERS

The Company is subject to federal, state and local environmental laws and
regulations that impose limitations on the discharge of pollutants into the
environment and establish standards for the treatment, storage, recycling, and
disposal of toxic and hazardous wastes. The Company has established reserves for
environmental costs, which are described under Item 7. "Management's Discussion
and Analysis of Financial Condition and Results of Operations - Environmental
Matters"; and expects to record additions to such reserves in the future
periods, to the extent appropriate, as environmental reviews and assessments are
conducted during 2001 and estimates of the environmental remediation costs
become available.

ITEM 2. PROPERTIES

AIRCRAFT

As of December 31, 2000, 80% of the Company's aircraft were actively assigned as
compared with 77% and 78% as of December 31, 1999 and April 30, 1999,
respectively. During 2000, demand for flight services began to increase in the
Company's Domestic Oil and Gas and Other segment while demand for flight
services in the Company's International and Aeromedical segments declined.
Certain information regarding the Company's owned and leased fleet as of
December 31, 2000 is set forth in the following table:

(1) Equipped to fly under instrument flight rules ("IFR"). All other types
    listed can only fly under visual flight rules ("VFR"). See Item 1.
    "Business - Weather and Seasonal Aspects."

Of the 261 aircraft listed, the Company owns 142 and leases 119. Additionally,
the Company operates 18 aircraft that are owned or leased by customers that are
not reflected in the foregoing tables. Most of the owned aircraft collateralize
the Company's long-term debt.

The Company sells aircraft whenever they (i) become obsolescent, (ii) do not fit
into future fleet plans, or (iii) are surplus to the Company's needs. The
Company often sells its aircraft for more than their book value. However, the
Company may not be able to realize more than book value if it were to sell a
large number of aircraft in a short period of time.

FACILITIES

The Company currently leases its executive office space in Metairie, Louisiana
(Metropolitan New Orleans). The lease covers approximately 8,107 square feet and
expires on July 31, 2005.

The Company's principal operating facility is located on property leased from
The Lafayette Airport Commission at the Lafayette Regional Airport in Lafayette,
Louisiana. The lease covers approximately twenty-eight acres and seventeen
buildings, with an aggregate of approximately 135,000 square feet, housing the
Company's main operational and administrative offices and the main repair and
maintenance facility. The Company has extended this lease until completion of a
new facility to be leased from The Lafayette Airport Commission at the Lafayette
Regional Airport. The lease term for this new facility is for 20


                                       6
<PAGE>   9

years including three five-year renewal options. The new 253,000 square foot
facility is scheduled for completion in September 2001. This move will not have
a material effect on operating costs. Under the terms of this lease, there is a
commitment by the Company to fund $4 million of construction costs, in which
case the monthly lease payments for the first ten years of the lease will be
reduced by the amortization of $4 million over ten years at 7% per annum. The
Company expects that it will have to fund the $4 million.

The Company owns its Boothville, Louisiana operating facility. The property has
a 23,000 square foot building, a 7,000 square foot hangar, and landing pads for
35 helicopters.

The Company also leases property for 12 additional bases to service the oil and
gas industry throughout the Gulf and one base in California. Those bases that
represent a significant investment by the Company in leasehold improvements or

                  fifty-three acres, is under a lease that expires June 30,

                  Company has built a variety of operational and maintenance
                  facilities on this property, including landing pads for
                  forty-six helicopters. The Company believes that this facility
                  is the largest commercial heliport in the world.

         B.       Intracoastal City Base (Louisiana) - containing approximately
                  twenty-three acres under several leases in Vermilion Parish,

                  has built a variety of operational and maintenance facilities
                  on this property, including landing pads for forty-five
                  helicopters.

         C.       Houma-Terrebonne Airport (Louisiana) - containing
                  approximately fourteen acres and certain buildings leased
                  under four leases from the Houma-Terrebonne Airport
                  Commission, which expire on August 31, 2001. The Company has
                  landing pads for thirty helicopters on this property.

         D.       Galveston (Texas) - containing approximately four acres under
                  a lease that expires May 1, 2001. The Company has operations
                  and maintenance facilities totaling 7,200 square feet and
                  landing pads for 30 helicopters.

         F.       Fourchon (Louisiana) - containing approximately eight acres,
                  is under original lease expiring April 30, 2006. The Company
                  has landing pads for ten helicopters on this property.

The Company's other operations related bases in the United States are located
along the Gulf in Louisiana at New Orleans, Cameron and Lake Charles; in Texas
at Sabine Pass, Port O'Connor, and Rockport; in Alabama at Theodore; and in
California at Santa Barbara.

The Company operates also from offshore platforms that are provided without
charge by the owners of the platforms, although in certain instances the Company
is required to indemnify the owners against loss in connection with the
Company's use thereof.

Bases for the Company's international and air medical operations are generally
furnished by the customer.

The declaration and payment of dividends is at the discretion of the Board of
Directors. Future dividends are dependent upon, among other things, the
Company's results of operations, financial condition, cash requirements, future
prospects and other factors deemed relevant by the Board. On October 29, 1999,
the Board of Directors voted to suspend PHI's quarterly cash dividend payments.
A credit agreement to which the Company is a party generally restricts the
declaration or payment of dividends to 20% of net earnings for the previous four
fiscal quarters. See Item 8. "Financial Statements and Supplementary Data -
Notes to Consolidated Financial Statements, Note 4."

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

Management's Discussion and Analysis of Financial Condition and Results of
Operations ("MD&A") should be read in conjunction with the Company's
Consolidated Financial Statements for the year ended December 31, 2000, the
eight months ended December 31, 1999, and the years ended April 30, 1999, and
1998 and the related Notes to Consolidated Financial Statements.

OVERVIEW

Despite increased oil and gas prices during 2000 when compared to 1999, activity
and revenues of the Company in the Gulf of Mexico, its primary market, although
higher than in 1999, remain below the levels achieved in 1998. Additionally, the
Company's costs have not yet been fully aligned with revenues, and in the
Company's other segments, revenues declined as compared to 1999.

The Company's efforts to effect cost reductions and efficiency measures in
several areas have, for the most part, been offset by increased costs in other
areas, and its efforts to expand its areas of operation have been disappointing.
In late 2000, the Board of Directors approved a plan to restore profitability
that included further cost reductions, rate increases for helicopter services,
reductions in the work force, divestiture or discontinuance of marginal or
unprofitable business efforts, and disposition of redundant aircraft. As a
result of actions implemented to date, the Company recorded significant charges
in its results for 2000. In addition, a review of inventory produced a
significant writedown to record inventory at its estimated net realizable value.

The Company announced an increase in its published rates for helicopter service,
effective May 1, 2001 or upon expiration of existing customer contracts. This
increase followed an earlier increase announced by the Company, which was
effective January 1, 2001. Revenue may decrease as a result of the loss of some
customers unwilling to accept the Company's increased rates, which was
considered in announcing this latest rate increase.

As the management, the Board of Directors, and employees of PHI continue their
efforts to restore profitability, the Company expects that it may have to take
additional charges in 2001, and it will face other challenges to its progress.
It must make further increases in pilot and mechanic compensation necessary for
it to maintain competitive compensation. Also, as discussed

                                       10

below, the Company expects to incur environmental charges in 2001, and must deal
with the uncertainty of possible union job action.

<PAGE>   14
YEAR ENDED DECEMBER 31, 2000 COMPARED WITH YEAR ENDED DECEMBER 31, 1999 (see
Note 1 of the Notes to Consolidated Financial Statements included elsewhere in
this annual report)

For the years ended December 31, 2000 and 1999, the Company recorded significant
and special charges that resulted from a reduction in work force, asset
writedowns, increases in pilot compensation, and decisions to exit certain
operations. Where appropriate, the charges are allocated to the Company's
business segments and are included in the respective discussion of each segment.

Domestic Oil and Gas and Other

The Domestic Oil & Gas and Other segment revenues increased 8.7% to $149.1
million for 2000 compared to $137.1 million for the same period in 1999.
Increased domestic activity that resulted from increased oil and gas exploration
and production activities in the Gulf of Mexico, increased forest fire-fighting
activity, and rate increases implemented in January 2000 contributed to the
increase.

The segment had a $2.2 million operating loss in 2000 compared to a $3.1 million
operating loss for the same period in 1999. The 2000 loss included a $2.4
million charge for the write-down of inventory, $0.9 million for a retroactive
pay adjustment for pilots, and $0.8 million for severance costs that were
included in special charges. The operating loss in 1999 included $1.3 million of
special charges (see Special Charges within this discussion), $1.5 million in
charges for environmental remediation, and $1.7 million for the disposition of
slow-moving inventory. Operating margin of (1.5)% for 2000 compares to (2.2)%
for the same period last year. The decrease in operating loss was primarily due
to increased revenues, lower aircraft depreciation, and rate increases in
January 2000. Increases in pilot compensation, aircraft repairs and maintenance,
fuel, insurance, helicopter rent, and pilot training costs partially offset the
decrease in operating loss. The increased fuel costs were the result of both
increased flight activity and increased fuel prices.

International

The International segment's revenues decreased 2.8% to $21.7 million for 2000
compared to $22.3 million for the same period in 1999. Decreased revenues that
resulted from the closure of certain operations in South America were primarily
responsible for the decrease. Increased revenue of certain other foreign
locations partially offset the decrease.

The International segment had a $0.7 million operating loss for 2000 compared to
a $2.0 million operating loss for the same period in 1999. Operating margin of
(3.3)% for 2000 compares to (9.0)% for the same period last year. The operating
loss in 2000 included a $0.3 million charge for the write-down of inventory,
$0.1 million for a retroactive pay adjustment for pilots, and $0.1 million for
severance costs that were included in special charges. The operating loss in
1999 included $3.5 million of special charges (see Special Charges within this
discussion). In 2000, increased repairs, maintenance, and insurance, and the
decreased revenues also negatively impacted operating profit.

Aeromedical

The Aeromedical segment's revenue decreased 1.8% to $44.3 million for 2000
compared to $45.1 million during the same period in the prior year. The decrease
in revenues is primarily attributable to decreased revenue and activity in the
Company's AirEvac operations in Arizona. In November 1999, the Company
restructured its Arizona operations and reduced the number of its aircraft in
that operation.

The Aeromedical segment had an operating loss of $1.5 million for 2000 compared
to operating income of $0.5 million for the same period in 1999. The operating
loss in 2000 included a $0.7 million charge for the write-down of inventory and
$0.2 million for a retroactive pay adjustment for pilots. Operating margin was
(3.3)% for the year ended December 31, 2000 and compares to 1.1% for the same
period in 1999. In addition to the inventory write-down and the increased pilot
pay, increased repairs and maintenance, fuel, helicopter rental, and pilot
training costs, and the decreased revenues contributed to the lower operating
profit. Lower labor costs that were primarily attributable to AirEvac's
restructuring partially offset the decrease in operating profit.

Technical Services

Technical Services segment operating revenues for 2000 were $17.0 million
compared to $18.6 million in the prior year, a decrease of 8.4%. The decrease in
operating revenues was primarily attributable to work performed on two large
contracts for the refurbishment and overhaul of two helicopters and a large
parts sale, all occurring during the year ended December 31,


                                       12
<PAGE>   15

1999. An ongoing contract to provide maintenance to certain military aircraft
commenced in the second quarter of 2000, which partially offset the decrease.

Technical Services operating profit decreased to a $0.6 million operating loss
for the year compared to $3.0 million operating profit for 1999. The operating
loss in 2000 included a $0.9 million charge for the write-down of inventory and
$0.2 million for severance costs that were recorded in Special Charges. The
operating margin was (3.2)% in the year ended December 31, 2000 and 16.0% in the
year ended December 31, 1999.

OTHER INCOME, NET

Other income, net, was $3.2 million for 2000 as compared to $7.9 million for the
prior year. The other income, net, for 2000 included $4.0 million of net gains
on aircraft sales and other asset dispositions offset by $0.7 million equity in
net losses of investee companies. The net gains on aircraft sales and other
asset dispositions during 1999 were $8.7 million, offset by $0.8 million in
equity in net losses of investee companies.

DIRECT EXPENSES

Direct expenses for 2000 increased by $15.8 million, or 7.5%, to $225.6 million
compared to $209.8 million in the prior year. The direct expenses in 2000
included a $4.3 million charge for the write-down of inventory and $1.2 million
for a retroactive pay adjustment for pilots. In 1999, there were $1.5 million in
charges for environmental remediation and a $1.7 million charge for the
disposition of slow-moving inventory. The increase in 2000 was also due to the
increase in flight activity and higher repairs and maintenance, fuel, insurance,
helicopter rental, and pilot training costs.

Depreciation expense included in direct expenses for 2000 was $12.5 million
compared to $14.1 million in the prior year. Total depreciation expense was
$13.7 million and $15.3 million for the same two periods, respectively. The
decrease was attributable to a reduction in the number of owned aircraft and to
the change in estimated useful lives and residual values implemented in May
1999. (See Note 1 of the Notes to Consolidated Financial Statements included
elsewhere in this annual report).

SELLING, GENERAL, AND ADMINISTRATIVE EXPENSES

Selling, general, and administrative expenses for the year ended December 31,
2000 decreased by 1.6% to $18.2 million compared to $18.5 million in the same
period in the prior year. Selling, general, and administrative expense in 1999
included severance costs totaling $1.1 million. Adjusting for such severance
costs, selling, general, and administrative expense increased $0.8 million in
2000, which was mostly the result of higher bad debt provisions. The Company is
in the process of a thorough review of these expenses to attempt to reduce them
or retard further increases.

SPECIAL CHARGES

In the fourth quarter of 2000, in connection with the plan to restore
profitability, the Company recorded Special Charges of $3.6 million that
included severance costs of $1.1 million, impairment of an investment in and
receivables from a joint venture totaling $1.7 million, and impairment of
property and equipment of $0.8 million.

In April 1999, in connection with expense reduction efforts and management's
decision to recognize the impairment of assets as a result of decreased
activity, the Company recorded Special Charges of $4.8 million. The Special
Charges included impairment of certain foreign based joint ventures amounting to
$2.5 million, severance costs of $1.3 million, impairment of property and
equipment of $0.4 million, and other charges of $0.6 million.

INTEREST EXPENSE

Interest expense was $5.8 million for the year ended December 31, 2000 and $5.9
million for the year ended December 31, 1999. Lower debt levels during 2000,
compared to the debt levels in 1999, offset the effect of increased interest
rates in 2000.

INCOME TAXES

Income tax benefit for the year ended December 31, 2000 increased $2.6 million
to $5.5 million. The effective tax rates were 30.9% and 36.6% for the years
ended December 31, 2000 and 1999, respectively. The lower effective rate for the
year ended December 31, 2000 is the result of permanent differences between book
income and tax income and the effect of state income taxes.

EIGHT MONTHS ENDED DECEMBER 31, 1999 COMPARED WITH EIGHT MONTHS ENDED DECEMBER
31, 1998 (see Note 1 of the Notes to Consolidated Financial Statements included
elsewhere in this annual report)

For the eight months ended December 31, 1999 and 1998, the Company recorded
significant and special charges that resulted from restructuring, changes in
market conditions, and decisions by the Company to exit certain operations.
Where applicable, the charges are appropriately allocated to the Company's
business segments and are included in the respective discussion of each segment.

Domestic Oil and Gas and Other

The Domestic Oil & Gas and Other segment revenues decreased 19.6% to $91.0
million for the eight months ended December 31, 1999 compared to $113.2 million
during the same period in the prior year. The decrease was the result of the
decreased oil and gas exploration activities in the Gulf of Mexico.

The Domestic Oil & Gas and Other segment had a $2.3 million operating loss for
the eight months ended December 31, 1999 compared to $13.2 million operating
profit for the same period in 1998. The operating loss for the eight months
ended December 31, 1999 included $1.5 million in charges for environmental
remediation (see Environmental Matters within the Management's Discussion and
Analysis of Financial Condition and Results of Operations). Operating margin of
(2.5)% for the eight months ended December 31, 1999 compares to 11.6% for the
same period in 1998. The decreased operating profit was primarily due to the
significant decline in operating revenues and activities and to the $1.5 million
environmental costs recorded in the eight months ended December 31, 1999. Also,
as a percent of revenue, repairs and maintenance and labor costs were higher for
the eight months ended December 31, 1999. Lower aircraft depreciation,
insurance, and rent partially offset the decrease in operating profit.

International

The International segment revenues decreased 11.0% to $14.7 million for the
eight months ended December 31, 1999 compared to $16.5 million during the same
period in the prior year. The decreased revenues were primarily the result of
decreased activities for oil and gas customers in South America and Angola.

The International segment had $1.1 million of operating profit for the eight
months ended December 31, 1999 compared to a $0.8 million operating loss for the
same period in 1998. The operating loss for the eight months ended December 31,
1998 included $2.5 million of special charges (see Special Charges within this
discussion). The lower revenues along with increased maintenance and repair
costs negatively impacted operating profit for the eight months ended December
31, 1999.

Aeromedical

The Aeromedical segment revenues decreased 5.4% to $30.2 million for the eight
months ended December 31, 1999 compared to $32.0 million during the same period
in the prior year. The decrease in revenues is primarily attributable to
decreased revenue and activity in the Company's AirEvac operations in Arizona.

The Aeromedical segment had an operating loss of $0.5 million for the eight
months ended December 31, 1999 compared to operating profit of $1.8 million for
the same period in 1998. Operating margin was (1.6)% for the eight months ended
December 31, 1999 and compares to 5.7% for the same period in 1998. Increased
repairs and maintenance and the decreased revenues contributed to the lower
operating income.

Technical Services

Technical Services segment operating revenues for the eight months ended
December 31, 1999 were $10.5 million compared to $8.9 million in the prior year,
an increase of 17.2%. Technical Services operating profit increased to $1.5
million for the eight months ended December 31, 1999 compared to $1.2 million
for 1999. The operating margin was 14.7% in the eight months


                                       14
<PAGE>   17

ended December 31, 1999 and 13.3% in the eight months ended December 31, 1998.
The increase in operating revenues and operating margin was primarily
attributable to work performed on two large contracts for the refurbishment and
overhaul of two helicopters and a large parts sale, all occurring during the
eight months ended December 31, 1999.

OTHER INCOME, NET

Other income, net, was $5.9 million for the eight months ended December 31, 1999
as compared to $1.5 million for the same period in 1998. The other income, net,
for the eight months ended December 31, 1999 included $6.6 million of net gains
on aircraft sales and other asset dispositions. The net gains on aircraft sales
and other asset dispositions during the eight months ended December 31, 1998
were $1.4 million. Also, the eight months ended December 31, 1999 included $0.7
million equity in net losses of investee companies, which compares to $0.1
million equity in net income of investee companies recorded in the eight months
ended December 31, 1998.

DIRECT EXPENSES

Direct expenses for the eight months ended December 31, 1999 decreased by 3.4%
to $139.9 million compared to $144.9 million in the same period in 1998. The
decrease was due to the significant overall decline in operating activities and
lower aircraft depreciation, insurance, and rent expenses. The $1.5 million of
environmental remediation (see Environmental Matters within the MD&A) recorded
in the eight months ended December 31, 1999 and the Technical Services segment's
increase in cost of sales partially offset the decrease in direct expenses.
Also, as a percentage of revenue, repairs and maintenance and labor costs were
higher for the eight months ended December 31, 1999.

Depreciation expense included in direct expenses for the eight months ended
December 31, 1999 was $8.8 million compared to $10.0 million in the prior year.
Total depreciation expense was $9.7 million and $11.4 million for the same two
periods, respectively. The decrease was attributable to a reduction in the
number of owned aircraft and to the change in estimated useful lives and
residual values implemented in May 1999. (See Note 1 of the Notes to
Consolidated Financial Statements included elsewhere in this annual report).

SELLING, GENERAL, AND ADMINISTRATIVE EXPENSES

Selling, general, and administrative expenses for the eight months ended
December 31, 1999 increased by 3.7% to $12.4 million compared to $11.9 million
in the same period in the prior year. The increase was primarily due to an
increase in Y2K compliance and certain other computer programming costs, general
salary increases for administrative employees, and the reassignment of certain
employees to administrative positions. During the eight months ended December
31, 1999, the Company also recorded severance costs totaling $1.1 million in
selling, general, and administrative expenses related to a reduction in its
number of employees.

SPECIAL CHARGES

During the eight months ended December 31, 1998, in connection with management's
decision to recognize the impairment of assets as a result of decreased
activity, the Company recorded Special Charges of $2.5 million. The Special
Charges included impairment of certain foreign based joint ventures amounting to
$1.4 million and impairment of property and equipment of $1.1 million.

INTEREST EXPENSE

Interest expense was $4.0 million for the eight months ended December 31, 1999
and $4.1 million for the eight months ended December 31, 1998. The decrease was
primarily due to slightly lower debt levels during the eight months ended
December 31, 1999, compared to the debt levels in same period in 1998.

INCOME TAXES

Income tax benefit for the eight months ended December 31, 1999 was $1.3 million
and the income tax expense for the eight months ended December 31, 1998 was $3.6
million. The effective tax rates were 31.7% and 41.0% for the two periods,
respectively. The lower effective rate for the eight months ended December 31,
1999 is the result of permanent differences between book income and tax income.

YEAR ENDED APRIL 30, 1999 COMPARED WITH THE YEAR ENDED APRIL 30, 1998

For the year ended April 30, 1999, the Company recorded significant and special
charges that resulted from restructuring, changes in market conditions, and
decisions by the Company to exit certain operations. Where applicable, the
charges are appropriately allocated to the Company's business segments and are
included in the respective discussions of each segment.

Domestic Oil and Gas and Other

The Domestic Oil & Gas and Other segment revenues decreased 2.8% to $159.3
million for the year ended April 30, 1999 compared to $163.9 million during the
same period ended April 30, 1998. The decrease was the result of the decreased
oil and gas exploration activities in the Gulf of Mexico.

The Domestic Oil & Gas and Other segment had $12.7 million operating profit for
the year ended April 30, 1999 compared to $19.3 million operating profit for the
same period ended April 30, 1998. The operating profit for the year ended April
30, 1999 included $1.3 million of special charges (see Special Charges within
this discussion) and $1.7 million for the disposition of slow-moving inventory.
Operating margin of 8.0% for the year ended April 30, 1999 compares to 11.8% for
the same period in 1998. The decreased operating profit was primarily due to the
decline in operating revenues and activities, the inventory provision and
special charges, and higher depreciation expense and labor costs recorded in the
year ended April 30, 1999.

International

The International segment revenues increased 5.7% to $24.1 million for the year
ended April 30, 1999 compared to $22.8 million during the same period ended
April 30, 1998. The increased revenues were primarily the result of increased
activities in Angola.

The International segment had a $4.0 million operating loss for the year ended
April 30, 1999 compared to less than a $0.1 million operating loss for the same
period ended April 30, 1998. The operating loss for the year ended April 30,
1999 included $6.0 million of special charges (see Special Charges within this
discussion).

Aeromedical

The Aeromedical segment revenues increased 30.5% to $46.8 million for the year
ended April 30, 1999 compared to $35.9 million during the same period ended
April 30, 1998. The increase in revenues was attributable to the benefit of a
full year of results of the Company's AirEvac operations in Arizona. The Company
acquired AirEvac in December 1997.

The Aeromedical segment had operating profits of $2.9 million for each of the
years ended April 30, 1999 and 1998. Operating margin was 6.1% for the eight
months ended December 31, 1999 and compares to 8.0% for the same period in 1998.
Increased overhead as a result of the AirEvac acquisition contributed to the
lower operating profit as a percent of revenue.

Technical Services

The Technical Services segment operating revenues for the year ended April 30,
1999 were $17.1 million compared to $14.0 million in the same period ended April
30, 1998, an increase of 21.9%. Technical Services operating profit decreased to
$2.7 million for the year ended April 30, 1999 compared to $2.8 million for the
year ended April 30, 1998. The operating margin was 15.6% in the year ended
April 30, 1999 and 19.9% in the year ended April 30, 1998. The increase in
operating revenues was primarily attributable to work performed on two large
contracts for the refurbishment and overhaul of two helicopters and a large
parts sale, all occurring during the year ended April 30, 1999.

OTHER INCOME, NET

Other income, net, was $3.5 million for the year ended April 30, 1999 as
compared to $2.3 million for the same period ended April 30, 1998. The other
income, net, for the year ended April 30, 1999 included $3.6 million of net
gains on aircraft sales and other asset dispositions. The net gains on aircraft
sales and other asset dispositions during the year ended April 30, 1998 were
$3.2 million. Also, the year ended April 30, 1998 included a $1.0 million charge
related to the discontinuance of a joint venture in South America.


                                       16
<PAGE>   19

DIRECT EXPENSES

Direct expenses for the year ended April 30, 1999 increased by 5.5% to $214.5
million compared to $203.4 million in the same period ended April 30, 1998. The
increase was due to the $1.7 million charge for the disposition of slow-moving
inventory, the Technical Services segment's increase in cost of sales, increased
aircraft depreciation, and the full year of AirEvac's expenses recorded for the
year ended April 30, 1999.

Depreciation expense included in direct expenses for the year ended April 30,
1999 was $15.3 million compared to $11.8 million in the prior year. Total
depreciation expense was $16.2 million and $12.5 million for the same two
periods, respectively. The increase was attributable to the acquisition of
additional aircraft and to the acquired AirEvac assets.

SELLING, GENERAL, AND ADMINISTRATIVE EXPENSES

Selling, general, and administrative expenses for the year ended April 30, 1999
increased by 1.2% to $18.0 million compared to $17.8 million in the same period
ended April 30, 1998. The increase was primarily due to the full year of
AirEvac's expenses recorded for the year ended April 30, 1999. The increase was
partially offset by a decline in computer software costs.

SPECIAL CHARGES

During the year ended April 30, 1999, in connection with expense reduction
efforts and management's decision to recognize the impairment of assets as a
result of decreased activity, the Company recorded Special Charges of $7.3
million. The Special Charges included impairment of certain foreign based joint
ventures amounting to $3.8 million, severance costs of $1.3 million, impairment
of property and equipment of $1.6 million, and other charges of $0.6 million.

INTEREST EXPENSE

Interest expense was $6.0 million for the year ended April 30, 1999 and $5.1
million for the year ended April 30, 1998. The increase was primarily due to
higher debt levels that resulted from the Company's AirEvac acquisition.

INCOME TAXES

Income tax expense for the year ended April 30, 1999 was $2.0 million and the
income tax expense for the year ended April 30, 1998 was $5.1 million resulting
in effective tax rates of 40.6% and 40.7% respectively.

                         LIQUIDITY AND CAPITAL RESOURCES

The Company's cash position as of December 31, 2000 was $0.9 million compared to
$1.7 million at December 31, 1999. Working capital decreased $13.2 million from
$54.7 million at December 31, 1999 to $41.5 million at December 31, 2000. Net
cash provided by operating activities during the year ended December 31, 2000
was $9.4 million. Net cash provided by operating activities and $24.1 million of
aircraft sales funded payments of long-term debt and purchases of property and
equipment.

Total long-term debt including capital lease commitments decreased $2.8 million
from December 31, 1999 to $74.9 million at December 31, 2000. The current
portion of the long-term debt was $9.7 million at December 31, 2000. On January
31, 2001, the revolving credit facility portion of the Company's credit
agreement converted to a term loan, thereby increasing total annual principal
payments on long term debt to approximately $13 million. As a result of its
losses, PHI was not in compliance with certain of its loan covenants in 2000,
but did obtain appropriate waivers from its lenders, as well as amendments to
certain covenant requirements during 2001, in return for additional collateral.
The Company is in discussions with its bank group to restructure its credit
agreement to include an extension of the conversion date of its revolving credit
facility and make other changes to the credit agreement's terms and conditions.

The Company's primary credit facility consists of a $45.0 million revolving
credit facility that converted to a term loan on January 31, 2001 (the "term
loan") and a capital loan facility of $30 million (the "capital loan"). There is
no additional capacity for borrowing under these facilities, nor is other
borrowing permitted. The capital loan is payable in fixed quarterly principal
payments of $1.0 million until maturity on November 10, 2005 and the term loan
is payable in quarterly installments of principal of approximately $2.25
million. The current interest rate on these facilities is LIBOR plus 3%, an
effective rate of 8.61% at March 15, 2001. As a result of its operating losses,
the Company was not in compliance with certain of its debt


                                       17
<PAGE>   20

covenants at December 31, 2000, but did obtain from its lenders appropriate
waivers, as well as amendments to certain covenant requirements during 2001 in
return for additional collateral.

The amount spent for the purchase and completion of aircraft improvements and
engines and other property and equipment was $28.2 million for 2000, compared to
$22.3 million for the twelve months ended December 31, 1999. At December 31,
2000, the Company had purchase commitments to purchase property and equipment
for approximately $11.2 million.

The Company will lease a new principal operating facility for twenty years,
effective September 2001. Under the terms of the new facility lease, the Company
has committed to fund $4.0 million of construction costs. Any such amounts
funded by PHI will amortize over 10 years at 7% per annum and the resulting
monthly amortization amounts will reduce PHI's monthly lease payments for the
first 10 years of the lease.

The Company believes that the combination of cash flow from operations and
aircraft sales will fund required debt principal and interest payments and
necessary capital expenditures during 2001. Capital expenditures, including
expenditures for aircraft fleet upgrade, will be limited and will continue to be
so until the Company is able to reverse its losses and generate an acceptable
cash flow from operations.

                          NEW ACCOUNTING PRONOUNCEMENTS

In June 1998, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards ("SFAS") No. 133, Accounting for Derivative
Instruments and Hedging Activities. SFAS No. 133 was subsequently amended by
SFAS 137 in June 1999 and SFAS 138 in September 2000. SFAS No. 133 as amended,
establishes accounting and reporting standards for derivative instruments and
hedging activities and requires, among other things, that an entity recognize
all derivatives as either assets or liabilities in the balance sheet and measure
those instruments at fair value. The Company will adopt the accounting standard
effective for its fiscal year beginning January 1, 2001, as required. Management
does not expect the adoption of SFAS 133 to have a significant impact on the
financial position, results of operations, or cash flows of the Company.

In December 1999, the Securities and Exchange Commission issued Staff Accounting
Bulletin ("SAB") No. 101, "Revenue Recognition in Financial Statements." SAB No.
101 summarizes certain of the SEC's views in applying generally accepted
accounting principles to revenue recognition in financial statements. SAB No.
101, as amended, was effective beginning in the fourth quarter of fiscal year
2000. Management has concluded that its existing revenue recognition policies
comply in all material respects with the guidance in SAB No. 101.

                              ENVIRONMENTAL MATTERS

Since 1996, the Company has conducted environmental reviews and assessments at
selected domestic bases and currently has recorded an aggregate estimated
liability of $3.0 million for environmental remediation costs that were probable
and estimable at December 31, 2000. The Company recorded no significant
additional provisions for the year ended December 31, 2000. However, the Company
began conducting environmental site surveys at its Lafayette facility in late
2000, and the Company anticipates that it will also conduct environmental site
surveys at certain other facilities during 2001. As a result of information
available to date, it is expected that the results of these surveys will require
additional provisions for environmental remediation costs in 2001, but the
Company is currently unable to estimate the amount of additional provisions that
may be necessary.

                                UNION JOB ACTION

As a result of unsuccessful attempts to negotiate a bargaining agreement with
the union elected to represent its pilots, on March 23, 2001, the union and the
Company were in a position to take so called "self-help" measures to strengthen
their positions. The union has indicated that it plans to conduct a campaign of
selected work stoppages and other disruptive actions. The Company has developed
contingency plans to cope with these actions but is unable at this time to
predict the effect of any union actions on its revenues and earnings.

ITEM 7.A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company is exposed to market risks associated with interest rates. The
Company makes limited use of derivative financial instruments to manage risks
associated with existing or anticipated transactions. All derivatives used for
risk management are closely monitored by the Company's senior management. The
Company does not hold derivatives for trading purposes and it does not use
derivatives with leveraged or complex features. Derivative instruments are
traded either with creditworthy major financial institutions or over national
exchanges.

At December 31, 2000, the Company was a party to interest rate swaps with
notional amounts totaling $40.0 million that were designed to convert a similar
amount of variable-rate debt to fixed rates. The swaps mature in 2003. The swaps
require the Company to pay an average interest rate of 5.78% on the notional
amount and, in turn, receive LIBOR interest rates. The variable interest rate
received by the Company under each swap contract is repriced quarterly. The
Company considers these swaps to be a hedge against potentially higher future
interest rates. As described in Note 8 to the consolidated financial statements,
the estimated fair value of these interest rate swaps was less than $0.1 million
at December 31, 2000.

At December 31, 2000, $72.5 million of the Company's long-term debt had variable
interest rates of which $40.0 million was effectively converted to fixed
interest rates through the interest rate swaps. Based on debt outstanding and
interest rate swap agreements in place at December 31, 2000, a 100 basis point
increase in variable interest rates would increase the Company's interest
expense in the year ending 2001 by $0.7 million.

                  PETROLEUM HELICOPTERS, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1)      SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         Nature of Operations, Basis of Consolidation, and Other General
         Principles

         Since its inception, Petroleum Helicopters, Inc.'s primary business has
         been to transport personnel and, to a lesser extent, parts and
         equipment, to, from and among offshore platforms for customers engaged
         in the oil and gas exploration, development, and production industry.
         The Company also provides aircraft maintenance services to third
         parties and air medical transportation services for hospitals and
         medical programs.

         The consolidated financial statements include the accounts of Petroleum
         Helicopters, Inc. and its majority-owned subsidiaries ("PHI" or the
         "Company") after the elimination of all significant intercompany
         accounts and transactions. For its investments of 20% to 50% in
         affiliates, which are primarily foreign affiliates, the Company uses
         the equity method of accounting.

         Current Developments

         In late 2000, the Board of Directors approved a plan to restore the
         profitability of the Company that included cost reductions, rate
         increases for helicopter services, reductions in the work force,
         divesture or discontinuance of marginal or unprofitable business
         efforts, and disposition of redundant aircraft. Further, the Company is
         in the process of restructuring its maintenance operations at its main
         facility in Lafayette, Louisiana and a review of inventory produced a
         $4.3 million writedown to record inventory at its estimated net
         realizable value. The Company anticipates that it will take several
         months for its operations to reflect the results of these actions.

         The Company's primary credit facility consists of a $45.0 million
         revolving credit facility that converted to a term loan on January 31,
         2001 and a capital loan facility of $30.0 million (see Note 4 to the
         Consolidated Financial Statements). There currently is no additional
         capacity for borrowing under these facilities, nor is other borrowing
         permitted. The capital loan is payable in fixed quarterly payments of
         $1.0 million until maturity on November 10, 2005 and the converted
         revolver is payable in fixed quarterly principal payments of $2.25
         million. The credit facility is subject to certain financial covenants,
         which include maintaining certain levels of working capital, tangible
         net worth, and cash flow coverage; and contains other provisions that
         restrict capital expenditures and payment of dividends. As a result of
         its operating losses, the Company was not in compliance with certain of
         its debt covenants as of December 31, 2000, but did obtain from its
         lenders appropriate waivers as well as amendments to certain covenant
         requirements during 2001 in return for additional collateral. The
         Company is in discussions with its bank group to restructure its credit
         agreement to include a postponement of the conversion of its revolving
         credit facility and make other changes to the credit agreement's terms
         and conditions. The Company believes that the combination of cash flows
         from operations and aircraft sales will fund required debt principal
         and interest payments and necessary capital expenditures during 2001.

         On March 10, 2000, the Company's pilots voted to become organized under
         the Office and Professional Employees International Union ("OPEIU"). As
         a result of unsuccessful attempts to negotiate a bargaining agreement
         with the OPEIU, on March 23, 2001, the union and the Company were in a
         position to take so called "self-help" measures to strengthen their
         positions. The union has indicated that it plans to conduct a campaign
         of selected work stoppages and other disruptive actions. The Company
         has developed contingency plans to cope with these actions, but is
         unable at this time to predict the effect of any union action on its
         revenues and earnings.

         Revenue Recognition

         The Company recognizes revenue related to aviation transportation
         services after the services are preformed or the contractual
         obligations are met. Aircraft maintenance service revenues are
         generally recognized at the time the repair or service work is
         completed. Revenues related to emergency flights generated by the
         Company's subsidiary, Air Evac Services, Inc. ("AirEvac") are recorded
         net of contractual allowances under agreements with third party payors
         when the services are provided.

         Fiscal Year Change

         Effective December 31, 1999, the Company changed its fiscal year-end to
         December 31 of each year. The consolidated statements of operations,
         shareholders' equity and cash flows for the period from May 1, 1999 to
         December 31, 1999 represent a transition period of eight months, which
         is referred to as the eight months ended December 31, 1999.

         The following is a comparative summary of the operating results for
         years ended December 31, 2000 and December 31, 1999 and the eight month
         periods ended December 31, 1999 and December 31, 1998:

         Use of Estimates

         The preparation of financial statements in conformity with accounting
         principles generally accepted in the United States of America requires
         management to make estimates and assumptions that affect the reported
         amounts of assets and liabilities and the disclosure of contingent
         assets and liabilities at the date of the financial statements, as well
         as reported amounts of revenues and expenses during the reporting
         period. Actual results could differ from those estimates.

         Cash Equivalents

         The Company considers cash equivalents to include demand deposits and
         investments with original maturity dates of three months or less.

         Inventories

         The Company's inventories are stated at the lower of average cost or
         market and consist primarily of spare parts and aviation fuel. Portions
         of the Company's inventories are used parts that are often exchanged
         with parts removed from aircraft. The Company uses systematic valuation
         procedures to estimate the cost of the used parts. Valuation reserves
         related to obsolescent and excess inventory were $3.7 million, $2.2
         million and $2.2 million at December 31, 2000 and 1999 and April 30,
         1999, respectively.

         Change in Accounting Estimate

         Effective May 1, 1999, the Company changed the estimated useful lives
         on its aircraft from ten years to fifteen years and also increased the
         residual values from 25% to 30%. The Company believes the revised
         estimated useful lives and residual values more appropriately reflect
         its financial results by better matching costs over the estimated
         useful lives of these assets. The effect of this change on net income
         for the eight months ended December 31, 1999 was an increase of
         approximately $1.1 million ($0.21 per diluted share).

         Property and Equipment

         The Company records its property and equipment at cost less accumulated
         depreciation. For financial reporting purposes, the Company uses the
         straight-line method to compute depreciation based upon estimated
         useful lives of fifteen years for flight equipment and three to ten
         years for other equipment. Generally, the Company uses a 30% residual
         value in the calculation of depreciation for its flight equipment. The
         Company uses accelerated depreciation methods for tax purposes. Upon
         selling or otherwise disposing of property and equipment, the Company
         removes the cost and accumulated depreciation from the accounts and
         reflects any resulting gain or loss in earnings at the time of sale or
         other disposition.

         The Company defers any gains resulting from the sale and leaseback of
         assets and amortizes the gain over the lease term. For the year ended
         December 31, 2000, the eight months ended December 31, 1999, and the
         years ended April 30, 1999 and 1998, the gains deferred on sale and
         leaseback transactions were $2.9 million, $1.2 million, $0.6 million,
         and $1.7 million, respectively.

         The Company reviews its long-lived assets and certain identifiable
         intangibles for impairment whenever events or changes in circumstances
         indicate that the carrying amount of an asset may not be recoverable.
         The Company measures recoverability of assets to be held and used by
         comparing the carrying amount of an asset to future undiscounted net
         cash flows that it expects the asset to generate. When an asset is
         determined to be impaired, the Company recognizes the impairment
         amount, which is measured by the amount that the carrying value of the
         asset exceeds its fair value. Similarly, the Company reports assets
         that it expects to sell at the lower of the carrying amount or fair
         value less costs to sell.

         Self-Insurance

         The Company maintains a self-insurance program for a portion of its
         health care costs. Self-insurance costs are accrued based upon the
         aggregate of the liability for reported claims and the estimated
         liability for claims incurred but not reported.

         The Company does not presently have any significant obligations for
         post employment benefits.

         Concentration of Credit Risk

         Financial instruments that potentially expose the Company to
         concentrations of credit risk consist primarily of cash and cash
         equivalents and trade accounts receivable. The Company places its
         short-term invested cash in overnight repurchase agreements with a
         bank. The Company does not believe significant credit risk exists with
         respect to these securities at December 31, 2000.

         PHI conducts a majority of its business with major and independent oil
         and gas exploration and productions companies with operations in the
         Gulf of Mexico. The Company also provides services to the medical
         centers, ambulance services, and U. S. and foreign governmental
         agencies. The Company continually evaluates the financial strength of
         its customers but generally does not require collateral to support the
         customer receivables. The Company establishes an allowance for doubtful
         accounts based upon factors surrounding the credit risk of specific
         customers, current market conditions, and other information. The
         allowance for doubtful accounts was $2.2 million, $0.8 million and $1.7
         million at December 31, 2000, December 31, 1999, and April 30, 1999,
         respectively. The Company's largest domestic oil and gas customer
         accounted for $27.2 million, $19.7 million, $41.1 million, and $38.4
         million of consolidated operating revenues for year ended December 31,
         2000, the eight months ended December 31, 1999, and years ended April
         30, 1999 and 1998, respectively. The Company also carried accounts
         receivable from this same customer totaling 12%, 13%, and 15% of net
         trade accounts receivable on December 31, 2000, December 31, 1999, and
         April 30, 1999, respectively.

         Stock Compensation

         The Company uses the intrinsic value method of accounting for employee
         stock-based compensation prescribed by Accounting Principles Board
         (APB) Opinion No. 25 and, accordingly, follows the disclosure-only
         provisions of Statement of Financial Accounting Standards No. 123,
         "Accounting for Stock-Based Compensation". See Note 6.

         Accounting for Computer Software

         In March 1998, the American Institute of Certified Public Accountants
         issued Statement of Position (SOP) No. 98-1, "Accounting for the Costs
         of Computer Software Developed or Obtained for Internal Use," which
         establishes criteria for when these types of costs should be expensed
         as incurred or capitalized. The Company has implemented SOP 98-1 on a
         prospective basis as of May 1, 1998 resulting in approximately $1.2
         million of costs being capitalized during the year ended April 30, 1999
         that would have been expensed under the Company's previous accounting
         method for such costs. This increased net earnings by $0.7 million or
         $0.13 per diluted share for the year ended April 30, 1999.
         Post-implementation costs are being expensed in accordance with the SOP
         and capitalized costs are being amortized over their estimated useful
         life.

         Income Taxes

         The Company provides for income taxes using the asset and liability
         method under which deferred tax assets and liabilities are recognized
         for the future tax consequences attributable to differences between the
         financial statement carrying amounts of existing assets and liabilities
         and their respective tax bases. The deferred tax assets and liabilities
         measurement uses enacted tax rates that are expected to apply to
         taxable income in the years in which those temporary differences are
         expected to be recovered or settled. The Company recognizes the effect
         of any tax rate changes in income of the period that included the
         enactment date.

         Earnings per Share

         The Company computes basic earnings (loss) per share by dividing income
         available to common stockholders by the weighted average number of
         common shares outstanding during the period. The diluted earnings
         (loss) per share computation uses the weighted average number of shares
         outstanding adjusted for incremental shares attributed to dilutive
         outstanding options to purchase common stock and non-vested restricted
         stock awards. The diluted share base for the year ended December 31,
         2000 and the eight months ended December 31, 1999 excludes incremental
         shares of 10,488 and 34,972, respectively, related to employee stock
         options and restricted stock awards that are antidilutive as a result
         of the Company's net loss for those periods.

         Derivative Financial Instruments

         The Company uses interest rate swap agreements to manage its interest
         rate exposure. The Company specifically designates these agreements as
         hedges of debt instruments and recognizes interest differentials as
         adjustments to interest expense in the period the differentials occur.
         Under interest rate swap agreements, the Company agrees with other
         parties to exchange, at specific intervals, the difference between
         fixed-rate and variable-rate interest amounts calculated by reference
         to an agreed-upon notional principal amount. The Company has estimated
         the fair value of the interest rate swap agreements using quotes from
         counterparties. The fair value of the agreements represents the cash
         effect if the Company had settled the existing agreements at December
         31, 2000 and 1999 and April 30, 1999. See Note 4 and Note 8 of these
         consolidated financial statements.

         New Accounting Pronouncements

         In June 1998, the Financial Accounting Standards Board ("FASB") issued
         Statement of Financial Accounting Standards ("SFAS") No. 133,
         Accounting for Derivative Instruments and Hedging Activities. SFAS No.
         133 was subsequently amended by SFAS 137 in June 1999 and SFAS 138 in
         September 2000. SFAS No. 133, as amended, establishes accounting and
         reporting standards for derivative instruments and hedging activities
         and requires, among other things, that an entity recognize all
         derivatives as either assets or liabilities in the balance sheet and
         measure those instruments at fair value. The Company will adopt the
         accounting standard effective for its fiscal year beginning January 1,
         2001, as required. Management does not expect the adoption of SFAS 133
         to have a significant impact on the financial position, results of
         operations, or cash flows of the Company.

         In December 1999, the Securities and Exchange Commission issued Staff
         Accounting Bulletin ("SAB") No. 101, "Revenue Recognition in Financial
         Statements." SAB No. 101 summarizes certain of the SEC's views in
         applying generally accepted accounting principles to revenue
         recognition in financial statements. SAB No. 101, as amended, was
         effective beginning in the fourth quarter of fiscal year 2000.
         Management has concluded that its existing revenue recognition policies
         comply in all material respects with the guidance in SAB No. 101.

         During the year ended December 31, 2000, in connection with
         management's decision to reduce costs and to recognize the impairment
         of certain assets, the Company recorded Special Charges of $3.6 million
         ($2.5 million on an after tax basis or $0.48 per diluted share).
         Additionally, the Company recorded a $4.3 million charge for the write
         down of inventory, included in direct expenses, as a result of an
         analysis of its overhaul and maintenance operations including
         requirements for its fleet. At December 31, 2000, the Company carried a
         liability for the $1.1 million of severance and related costs shown
         above, of which substantially all was paid in the first quarter of
         2001.

         During the year ended April 30, 1999, in connection with management's
         decision to reduce costs and to recognize the impairment of assets as a
         result of decreased activity, the Company recorded Special Charges of
         $7.3 million ($4.4 million on an after tax basis or $0.84 per diluted
         share). Additionally, a charge of $1.7 million was recognized during
         the year-ended April 30, 1999 for the disposition of slow moving
         inventories and is included in direct expenses. At April 30, 1999, $0.8
         million of these charges remained in accrued liabilities, which was
         comprised of $0.3 million for employee severance / benefits and $0.5
         million for other charges; substantially all of which was paid by
         December 31, 1999.

         On November 30, 1998, the Company and its principal lending group
         entered into a loan agreement that amended and restated its original
         loan agreement dated January 1, 1986. This amended and restated
         agreement was further amended subsequent to November 30, 1998. The most
         recent amendment occurred on March 29, 2001. The agreement provides a
         $40.0 million revolving credit facility and a $40.0 million term credit
         facility. The loan is secured by substantially all of the Company's
         assets. The secured term and revolving loan agreement permits both
         prime rate based borrowings and "LIBOR" borrowings plus a spread. The
         spread for LIBOR borrowings is 3.0%. The term credit facility is
         payable in fixed quarterly principal payments of $1.0 million until
         maturity on November 10, 2005. At December 31, 2000, December 31, 1999,
         and April 30, 1999, $30.0 million, $36.0 million and $39.0 million,
         respectively, was outstanding on the term credit facility. On January
         31, 2001, the revolving credit facility converted to a term loan. At
         December 31, 2000, December 31, 1999, and April 30, 1999, $37.5
         million, $29.5 million, and $26.5 million, respectively, was
         outstanding on the revolving credit facility. The Company paid a 0.38%
         commitment fee on the unused portion of the revolving credit facility.
         The commitment fee was less than $0.1 million for each of the year
         ended December 31, 2000, the eight months ended December 31, 1999, and
         the years ended April 30, 1999 and 1998. Under the converted term loan,
         quarterly installments of $1.9 million, beginning April 30, 2001, are
         due through its October 31, 2005 maturity.

         On January 29, 1999, the Company's wholly-owned subsidiary, AirEvac and
         the Company's principal lending group amended its original loan
         agreement dated December 31, 1997. This agreement provides $5.0 million
         and $6.25 million revolver and term credit facilities, respectively.
         This loan is secured by certain assets of AirEvac and is guaranteed by
         the Company. The loan agreement permits both prime rate based
         borrowings and LIBOR borrowings plus a spread. The spread is 3.0%.
         During 2000, the Company prepaid all remaining balances on its term
         credit facility. At December 31, 1999 and April 30, 1999, $4.5 million
         and $5.1 million, respectively, was outstanding on the term notes. On
         November 10, 2000, the revolver credit facility converted to a term
         loan. Under the converted term loan, twenty quarterly installments of
         $0.3 million, beginning February 10, 2001, are due until its November
         10, 2005 maturity. At each of December 31, 2000, December 31, 1999 and
         April 30, 1999, $5.0 million was outstanding on the revolving credit
         facility.

         The loan agreement with the principal lending group requires that the
         Company either prepay the term loans with proceeds from the sale of
         collateralized equipment or pledge additional equipment as collateral
         to replace the sold equipment. The credit facility is subject to
         certain financial covenants, which include maintaining certain levels
         of working capital, tangible net worth, and cash flow coverage; and
         contains other provisions that restrict capital expenditures and
         payment of dividends. The declaration or payment of dividends is
         restricted to 20% of net earnings for the previous four fiscal
         quarters. As a result of its operating losses, the Company was not in
         compliance with certain of its debt covenants at December 31, 2000, but
         did obtain from its lenders appropriate waivers as well as amendments
         to certain covenant requirements during 2001 in return for additional
         collateral with a net book value of $11.5 million. Such agreements also
         limit the creation, incurrence, or assumption of Funded Debt (as
         defined, which includes long-term debt) and the acquisition of
         investments in unconsolidated subsidiaries. At April 30, 1999, the
         Company received a waiver allowing the $9.0 million in special charges
         and inventory writedowns (see Notes to Consolidated Financial
         Statements, Note 2) to be excluded from the dividend restriction
         calculation, thus allowing the payment of dividends in May 1999.

         During 2000, the Company entered into a capital lease for two aircraft.
         Under the capital lease, the Company will begin making 72 monthly lease
         payments of less than $0.1 million on January 29, 2001 with a final
         payment of $1.4 million due on January 29, 2007. The implied interest
         rate on the capital lease is 9.36%. As a result of this transaction,
         the Company recorded $2.3 million in property, plant, and equipment and
         a related capital lease obligation for the same amount.

         As discussed in Note 1, the Company uses derivative instruments on a
         limited basis to manage risks related to interest rates. At each of
         December 31, 2000, December 31, 1999, and April 30, 1999, the Company
         had interest rate swap agreements with notional amounts totaling $40.0
         million that serve to convert an equal amount of variable rate
         long-term debt to fixed rates. The swaps mature in 2003 and require the
         Company to pay a weighted-average interest rate of 5.78% over their
         composite lives and to receive a variable rate, which was 6.76% at
         December 31, 2000. Based upon the current spread, the effect of these
         agreements is to limit interest rate exposure to 7.08% on $20.0 million
         of the Company's revolving credit facility, 7.69% on $10.0 million and
         7.27% on $10.0 million of the Company's term loan. Using the
         accrual/settlement method of accounting, the Company records the net
         amount to be received or paid under the swap agreements as part of
         interest expense in the Consolidated Statements of Operations. The
         interest rate


                                       32
<PAGE>   35

         swap agreements had the effect of reducing interest expense by $0.3
         million for the year ended December 31, 2000 and increasing interest
         expense by $0.1 million, $0.2 million and less than $0.1 million for
         the eight months ended December 31, 1999 and for the years ended April
         30, 1999 and 1998, respectively.

         Cash paid for interest, net of amounts paid or received in connection
         with the interest rate swaps was $5.8 million, $3.0 million $5.7
         million and $4.6 million for the year ended December 31, 2000, the
         eight months ended December 31, 1999, and the years ended April 30,
         1999 and 1998, respectively.

         No valuation allowance was recorded against the deferred tax assets
         because management believes that the deferred tax assets will more than
         likely be realized in full through future operating results and the
         reversal of taxable temporary differences. At December 31, 2000, other
         current assets includes $3.7 million of deferred tax assets.

         For Federal income tax purposes, the Company has net operating loss
         carryforwards ("NOLs") of approximately $4.4 million that, if not used
         will expire in 2021. In addition, the Company has foreign tax credits
         of approximately $2.4 million, which expire in 2004 through 2006. The
         Company also has approximately $0.8 million of alternative minimum tax
         credit carryforwards, which are not subject to expiration and are
         available to offset future regular income taxes subject to certain
         limitations. Additionally, for state income tax purposes, the Company
         has NOLs of approximately $8.0 million available to reduce future state
         taxable income. These NOLs expire in varying amounts beginning in 2012
         through 2021.

         Income taxes paid were approximately $0.6 million, $4.9 million, and
         $3.5 million for the eight months ended December 31, 1999 and the years
         ended April 30, 1999 and 1998, respectively. The Company received
         income tax refunds of approximately $2.2 million during the year ended
         December 31, 2000.

(6)      EMPLOYEE BENEFIT PLANS

         Savings and Retirement Plans

         The Company maintains an Employee Savings Plan under Section 401(k) of
         the Internal Revenue Code. Effective July 1999, the plan provides that
         the Company match 200% of up to 3% of employee contributions.
         Previously, the Company matched 100% of the first 3% of their
         contributions. The Company's contribution was $4.1 million, $2.4
         million, $2.1 million, and $1.7 million for the year ended December 31,
         2000, the eight months ended December 31, 1999, and the years ended
         April 30, 1999, and 1998, respectively.

         The Company maintains a Supplemental Executive Retirement Plan
         ("SERP"). The nonqualified and unfunded plan provides certain senior
         management with supplemental retirement and death benefits at age 65.
         The SERP plan provides supplemental retirement benefits that are based
         on each participant's salary at the time of entrance into the plan.
         Occasionally, the Company's board of directors may increase certain
         individuals' benefits. The benefit is one-third of each participant's
         annual salary of $200,000 or less, plus one-half of each participant's
         annual salary that is in excess of $200,000, if applicable. The plan
         does not provide for automatic benefit increases. During 2000, the
         Company's board of directors amended the plan to provide for partial
         vesting. The assumed discount rate was 6.85% for the year ended
         December 31, 2000 and 7.50% for the eight months ended December 31,
         1999 and the years ended April 30, 1999 and 1998. The Company recorded
         plan costs of $0.4 million for the year ended December 31, 2000 and
         $0.3 million for each of the eight months ended December 31, 1999 and
         the years ended April 30, 1999 and 1998.

         The SERP plan is an unfunded plan. However, the Company has purchased
         life insurance contracts in anticipation of using the life insurance's
         cash values and death benefits to help fulfill the obligations of the
         plan. The Company may sell or redeem the contracts at any time without
         any obligation to the plan participants.

         The Company maintains an Officer Deferred Compensation Plan and a
         Director Deferred Compensation Plan. The plans permit key officers and
         all directors to defer a portion of their compensation. The plans are
         nonqualified and unfunded.

         Stock Based Compensation and Other Compensation Plans

         Under PHI's 1992 Non-Qualified Stock Option and Stock Appreciation
         Rights Plan (the "Plan"), the Company may grant non-qualified stock
         options and stock appreciation rights to selected employees for up to
         100,000 shares of the


                                       34

         Company's non-voting common stock. Options issued under the plan may be
         exercisable at a price of not less than 25% of the related stock's fair
         market value at the date of grant. The options may be exercised any
         time after one year from the date of grant until their expiration at
         five years from such date. At December 31, 2000, there were no options
         or stock appreciation rights outstanding under the Plan and grants were
         available for 34,000 shares. The Company does not expect to issue any
         additional options or rights under the Plan.

         Under the PHI 1995 Incentive Plan (the "1995 Plan"), the Company is
         authorized to issue up to 175,000 shares of voting common stock and
         575,000 shares of non-voting common stock. In May 2000, the Company's
         Board of Directors increased the number of non-voting common stock
         available under the plan from 325,000 shares to 575,000 shares. The
         Compensation Committee of the Board of Directors is authorized under
         the 1995 Plan to grant stock options, restricted stock, stock
         appreciation rights, performance shares, stock awards, and cash awards.
         The exercise price of the stock option grants is equal to the fair
         market value of the underlying stock at the date of grant.

         During the years ended December 31, 2000 and April 30, 1998, the
         Company did not issue any shares, options, or rights under the 1995
         Plan. During the eight months ended December 31, 1999, the Company
         granted 30,000 voting stock options and 142,000 non-voting stock
         options under the 1995 Plan. The voting and non-voting stock options
         vest 25% on each of the first, second, third, and fourth anniversary
         date of the issues and expire on July 14, 2009. During the year ended
         April 30, 1999, the Company granted 11,691 non-voting restricted shares
         (net of forfeitures), 4,000 voting stock options, and 15,000 non-voting
         stock options under the 1995 Plan. The restricted shares had a fair
         value of $20.00 per share on the date of issue and will become
         unrestricted on July 31, 2001. The voting stock options are 100% vested
         and expire on July 30, 2007. The non-voting stock options vest 20% on
         each of the first through fifth anniversary date of the issue and
         expire on October 31, 2008.

         At December 31, 2000, there were 116,520 voting shares and 336,016
         non-voting shares available for issuance under the 1995 Plan. The
         Company has recorded $0.1 million of compensation expense related to
         the 1995 Plan in each of the year ended December 31, 2000, the eight
         months ended December 31, 1999, and the year ended April 30, 1999 and
         less than $0.1 million for the year ended April 30, 1998. The balance
         of unearned stock compensation expense to be amortized over future
         periods was less than $0.1 million at December 31, 2000.

         On October 30, 1998, the shareholders of PHI adopted the Directors
         Stock Compensation Plan (the "Directors Plan") to (i) allow all
         non-employee directors ("Directors") to receive his or her annual
         retainer in the form of PHI's non-voting common stock, and (ii) provide
         for the automatic annual grant of options to Directors to purchase
         2,000 shares of non-voting common stock. The Directors Plan also
         provides for the voluntary deferral of all or a portion of the stock
         awards or fees otherwise payable to each Director. All non-employee
         members of the Board of Directors of PHI participate in the Plan. The
         Company may issue up to 150,000 shares under the Directors Plan. The
         Company issued 547 shares and 2,388 deferred stock awards during the
         year ended December 31, 2000. The Company issued 1,277 shares and 4,908
         deferred stock awards during the eight months ended December 31, 1999.
         During the year ended December 31, 2000, the eight months ended
         December 31, 1999, and the year ended April 30, 1999, the Company
         issued 4,165, 10,000 and 6,000 options, respectively, to purchase
         non-voting common stock. At December 31, 2000, 120,715 shares were
         available for issue under the Directors Plan.

         The following table summarizes employee stock option activities for the
         year ended December 31, 2000, the eight months ended December 31, 1999,
         and the years ended April 30, 1999, and 1998. All of the options were
         issued with an exercised price equal to or greater than the market
         price of the stock at the time of issue.

         Statement of Financial Accounting Standards No. 123, "Accounting for
         Stock-Based Compensation," (SFAS No. 123), encourages the use of a fair
         value based method of accounting for compensation expense associated
         with stock option and similar plans. However, SFAS No. 123 permits the
         continued use of the intrinsic value based method prescribed by Opinion
         No. 25 but requires additional disclosures, including pro forma
         calculations of net earnings and earnings per share as if the fair
         value method of accounting prescribed by SFAS No. 123 had been applied.

         aircraft to Clintondale.

         In December 2000, the Company initiated discussions to exit its
         ownership interest in Clintondale. In conjunction with the plan, the
         Company recorded an impairment charge of $1.7 million to its investment
         in and advances to Clintondale.

 (9)     COMMITMENTS AND CONTINGENCIES

         Leases - The Company leases certain aircraft, facilities, and equipment
         used in its operations. The related lease agreements, which include
         both non-cancelable and month-to-month terms, generally provide for
         fixed monthly rentals and, for certain real estate leases, renewal
         options. The Company generally pays all insurance, taxes, and
         maintenance expenses associated with these aircraft and some of these
         leases contain renewal and purchase options. Rental expense incurred
         under these leases consisted of the following:

         The Company will lease a new principal operating facility for twenty
         years, effective September 2001. Under the terms of the new facility
         lease, there is a commitment by the Company, under certain
         circumstances, to fund $4.0 million of construction costs. The Company
         expects that it will have to fund the $4.0 million. Any such amounts
         funded by PHI will amortize over 10 years at 7% per annum and the
         resulting monthly amortization amounts will reduce PHI's monthly lease
         payments for the first 10 years of the lease.

         The following table presents the remaining aggregate lease commitments
         under operating leases having initial non-cancelable terms in excess of
         one year. The table includes projected lease payments for the new
         principal operating facility.

         Environmental Matters - The Company has conducted environmental reviews
         and assessments at certain of its operating bases. In connection with
         the assessments, the Company has recorded aggregated estimated
         liabilities of $3.0 million, $3.0 million, and $1.8 million for
         environmental remediation costs that were probable and estimable at
         December 31, 2000, December 31, 1999, and April 30, 1999. The Company
         recorded no significant additional provisions for the year ended
         December 31, 2000.

         The Company began conducting environmental site surveys in late 2000 at
         its Lafayette, Louisiana facility, which will be vacated in 2001 when
         the Company moves to its new facility. Initial phases of the surveys
         have identified certain contamination. However, until the surveys are
         complete, the Company cannot reasonably estimate the extent of that
         contamination and the associated costs of remediation. The Company
         expects to complete the survey during the second quarter of 2001. The
         Company anticipates that it will also conduct environmental site
         surveys at certain other Gulf Coast facilities during 2001. It is
         expected that the results of the surveys discussed above will require
         additional provisions for environmental remediation costs in 2001, but
         the Company is currently unable to estimate the amount of additional
         provisions that may be necessary.

         The Company expensed environmental costs, including provisions, of $0.3
         million, $1.5 million, $0.4 million, and $0.7 million for year ended
         December 31, 2000, the eight months ended December 31, 1999, and the
         years ended April 30, 1999, and 1998, respectively, related to
         remediation, monitoring, and prevention efforts.

         Legal Matters - The Company is named as a defendant in various legal
         actions which have arisen in the ordinary course of its business and
         have not been finally adjudicated. The amount, if any, of ultimate
         liability with respect to such matters cannot be determined. In the
         opinion of management, the amount of the ultimate liability with
         respect to


                                       38

         these actions will not have a material adverse effect on results of
         operations, cash flow or financial position of the Company.

         Purchase Commitments - At December 31, 2000, the Company had
         commitments to purchase seven aircraft for approximately $11.2 million.

(10)     BUSINESS SEGMENTS AND GEOGRAPHIC AREAS

         PHI is primarily a provider of helicopter services, including
         helicopter maintenance and repair services. The Company has used a
         combination of factors to identify its reportable segments as required
         by Statement of Financial Accounting Standards No. 131, "Disclosures
         about Segments of an Enterprise and Related Information" ("SFAS 131").
         The overriding determination of the Company's segments is based on how
         the chief operating decision-maker of the Company evaluates the
         Company's results of operations. The underlying factors include
         customer bases, types of service, operational management, physical
         locations, and underlying economic characteristics of the types of work
         the Company performs. During 2000, the Company modified its segment
         disclosure by segregating its previously reported Oil and Gas segment
         into three separate segments. The Company now identifies four segments
         that meet the requirements of SFAS 131 for disclosure. The reportable
         segments are Domestic Oil and Gas and Other, International,
         Aeromedical, and Technical Services. The Company also modified its
         methodology for allocating certain of its operating overhead costs.

         The Domestic Oil and Gas and Other segment provides helicopter services
         to oil and gas customers operating in the Gulf of Mexico. The Domestic
         Oil and Gas and Other segment also provides helicopter services to
         certain domestic governmental agencies involved with forest-fire
         fighting activities. The International segment provides helicopters in
         various foreign countries to oil and gas customers, including national
         oil companies, and certain U.S. and foreign governmental agencies. The
         Aeromedical segment provides helicopter services to hospitals and
         medical programs in several U.S. states. The Company's AirEvac
         subsidiary is included in the Aeromedical segment. The Technical
         Services segment provides helicopter repair and overhaul services for a
         variety of helicopter owners and operators.

         The following tables show information about the profit or loss and
         assets of each of the Company's reportable segments for the year ended
         December 31, 2000, the eight months ended December 31, 1999, and the
         years ended April 30, 1999 and 1998. The information contains certain
         allocations, including allocations of depreciation, rents, insurance,
         interest, and overhead expenses that the Company deems reasonable and
         appropriate for the evaluation of results of operations. The Company
         does not allocate other income, net, and corporate selling, general,
         and administrative costs to the segments. Where applicable, the tables
         present the unallocated amounts to reconcile the totals to the
         Company's consolidated financial statements. Prior year information has
         been restated to reflect the Company's current Segments. Segment assets
         are determined by where they are situated at period-end. Corporate
         assets are principally cash and cash equivalents, short term
         investments, other current assets, and certain property, plant, and
         equipment.

(12)     AIREVAC ACQUISITION

         On December 31, 1997, PHI purchased the net assets of Samaritan AirEvac
         for approximately $8.8 million. The purchase involved all of the
         operating assets and business of Samaritan AirEvac, an air medical
         services division of Samaritan Health System based in Arizona and a
         customer of PHI since June 12, 1993.

         The cost of the acquisition was recorded under the purchase method of
         accounting. The results of AirEvac's operations have been consolidated
         with the Company's results effective January 1, 1998.

         The following unaudited pro forma information presents a summary of
         consolidated results of operations as if the acquisition had occurred
         on May 1, 1997 with pro forma adjustments to give effects to

         with related income tax effects (in thousands, except per share
