PRIME MEDICAL SERVICES, INC.,

ANNUAL REPORT ON FORM 10-K

FOR THE FISCAL YEAR ENDED DECEMBER 31, 1999

PART I

ITEM 1. BUSINESS
- ------- --------

Prime Medical Services, Inc., a Delaware corporation ("Prime" or the
"Company"), is the largest provider of lithotripsy services in the United
States. Lithotripsy is a non-invasive procedure for the treatment of kidney
stones, typically performed on an outpatient basis, that eliminates the need for
lengthy hospital stays and extensive recovery periods associated with surgery.
The Company has 65 lithotripters of which 59 are mobile and six are fixed site.
The Company's lithotripters performed approximately 38,000 procedures in the
United States in 1999 through a network of approximately 450 hospitals and
surgery centers in 34 states.

Lithotripters fragment kidney stones by use of extracorporeal shock
wave lithotripsy. The Company provides services related to the operation of the
lithotripters, including scheduling, staffing, training, quality assurance,
maintenance, regulatory compliance and contracting with payors, hospitals and
surgery centers. Medical care is rendered by the urologists utilizing the
lithotripters. Management believes that the Company has collected the industry's
largest and most comprehensive lithotripsy database, containing detailed
treatment and outcomes data on over 160,000 lithotripsy procedures. The Company
and its associated urologists utilize this database in seeking to provide the
highest quality of lithotripsy services as efficiently as possible.

From 1992 through 1999, the Company completed 13 acquisitions involving
58 lithotripters. Since 1992, the Company has substantially divested its
original non-lithotripsy businesses.

During 1997 the Company acquired a 75% interest in a manufacturing
company which provides manufacturing services, and installation, refurbishment
and repair of major medical equipment for mobile medical services providers. The
primary intention of this acquisition was to provide vertical integration with
the lithotripsy business. However, the non-lithotripsy business of the
manufacturing segment has continued to increase. In addition to manufacturing
services for lithotripsy trailers, the manufacturing segment also provides
manufacturing services for magnetic resonance imaging ("MRI") trailers and
cardiac catheterization lab trailers.

During 1999 the Company completed two acquisitions in the rapidly
growing field of refractive vision correction (RVC). These two acquisitions
included six laser vision correction facilities which performed approximately
19,000 procedures during 1999. These facilities provide laser vision correction
of common refractive vision disorders such as myopia (nearsightedness),
hyperopia (farsightedness) and astigmatism.

There are currently two procedures that use the excimer laser ("laser")
to correct vision disorders: Laser in-situ Keratomileusis ("LASIK") and
Photorefractive Keratectomy ("PRK"). LASIK is an outpatient procedure that
accounts for nearly 90% of laser procedures done today. In LASIK, an ophthalmic
surgeon uses a special knife called a microkeratome to peal back the top layers
of the cornea and ablates the underlying corneal tissue with the laser before
replacing the corneal layer. LASIK has three key advantages over PRK
(photorefractive keratectomy) where the laser is used without creating the
corneal flap: less pain, shorter recovery time, and fewer visual side effects.
Patients' enthusiasm and word-of-mouth referrals for the procedure have been an
important part of LASIK's rapid adoption.

2



The Company has three reportable segments: lithotripsy, manufacturing
and RVC. Other operating segments, which do not meet the qualitative thresholds
for reportable segments, include prostatherapy services. See Note N to the
consolidated financial statements for segment disclosures.

Lithotripsy Segment Overview

- ----------------------------

Kidney stones develop from crystals made up primarily of calcium which
separate from urine and build up on the inner surfaces of the kidney. The exact
cause of kidney stone formation is unclear, and there is no known preventative
cure in the vast majority of cases. Approximately 25% of all kidney stones do
not pass spontaneously and therefore require medical or surgical treatment.
Kidney stone treatments used by urologists include lithotripsy, drug therapy,
endoscopic extraction or open surgery. While the nature and location of a kidney
stone impacts the choice of treatment, the Company believes the majority of all
kidney stones that require treatment are treated with lithotripsy because it is
non-invasive, typically requires no general anesthesia, and rarely requires
hospital stays. After fragmentation by lithotripsy, the resulting kidney stone
fragments pass out of the body naturally. Recovery from the procedure is usually
a matter of hours.

Kidney stone disease is most prevalent in the southern United States.
Men are afflicted with kidney stones more than twice as frequently as women,
with the highest incidence occurring in men 45 to 64 years of age. During 1999
the Company received approximately 79% of its revenues from the lithotripsy
segment.

Kidney Stone Treatment Methods

A number of kidney stone treatments are used by urologists ranging from
non-invasive procedures, such as drug therapy or lithotripsy, to invasive
procedures, such as endoscopic extraction or open surgery. The type of treatment
a urologist chooses depends on a number of factors, such as the size and
chemical make-up of the stone, the stone's location in the urinary system and
whether the stone is contributing to other urinary complications such as
blockage or infection.

Certain types of less common kidney stones may be dissolved by drugs
which allow normal passage from the urinary system. Stones located in certain
areas of the urinary tract may be extracted endoscopically. These procedures
commonly require general or local anesthesia and can injure the involved areas
of the urinary tract. Frequently, kidney stones are located where they are not
accessible by an endoscopic procedure. Prior to the development of lithotripsy,
stones lodged in the upper urinary tract were often treated by open surgery or
percutaneous stone removal, both major operations requiring an incision to gain
access to the stone. After such procedures, the patient typically spends several
days in the hospital followed by a convalescence period of three to six weeks.
As the technology for treating kidney stones has improved, there has been a
shift from more expensive and complicated invasive procedures to safer, more
cost efficient and less painful non-invasive procedures, such as lithotripsy.

Extracorporeal Shock Wave Lithotripsy

General. The lithotripter has dramatically changed the course of kidney
stone disease treatment since lithotripsy is normally performed on an outpatient
basis, often without general anesthesia. Recovery times are generally only a few
hours, and most patients can return to work the next day. There are two basic
types of lithotripsy treatment currently available: electromagnetic and
spark-gap. A decision regarding which type is used in any instance may depend on
several factors, among which are the treating physician's preferences, treatment
times, stone location, and anesthesia considerations. The Company has 51
electromagnetic machines and 14 spark-gap machines.

3



Electromagnetic Technology. Most new lithotripters utilize an
electromagnetic shock wave component that eliminates the need for disposable
electrodes. The use of lithotripters employing electromagnetic technology allows
for more precise focusing of shock wave energy and more predictable energy
delivery than other lithotripsy technologies, which eliminates the need for
anesthesia in most cases. Utilization of systems employing electromagnetic
technology usually results in fragmentation of the kidney stone in between 60
and 90 minutes.

Spark Gap Technology. With these lithotripsy systems, shock waves
generated by a disposable high-voltage spark electrode are focused on a kidney
stone. Utilization of systems employing spark gap technology usually results in
fragmentation of the kidney stone in less than 60 minutes. The use of spark-gap
technology often requires the administration of sedatives or intravenous
anesthesia care and in some cases requires general anesthesia.

Manufacturing Segment Overview

- ------------------------------

In September 1997, the Company, through its acquisition of a 75%
interest in AK Associates, L.L.C. ("AK"), began providing manufacturing services
and installation, upgrade, refurbishment and repair of major medical equipment
for mobile medical services providers. The Company paid $4.8 million for this
interest, plus an earn-out of $1.1 million, which was paid in February 1999.
Certain members of AK management own the remaining 25% of AK. During 1998 AK
became certified by General Electric Company ("GE") to provide trailers for MRI
equipment, and during 1999 AK became certified by two additional companies to
provide trailers for their equipment. These certifications have resulted in
increased revenues in the manufacturing segment. The Company received
approximately 16 % of its revenues from the manufacturing segment in 1999.

RVC Segment Overview

- --------------------

During 1999, the Company entered into the RVC field through two
acquisitions. Effective September 1, 1999, the Company acquired a 60% interest
in two refractive surgery centers, owned and operated by Barnet Dulaney Eye
Center, for approximately $8.8 million in cash, a warrant to purchase 29,000
shares of Company common stock and a contingent earn-out obligation to be paid
at the end of the first year of operations after acquisition. Also effective
September 1, 1999, the Company acquired, through a majority owned subsidiary,
60% of the outstanding stock of Horizon Vision Centers, Inc. ("Horizon") for
approximately $10.9 million in cash. Horizon operates four refractive surgery
centers. The Company received approximately 3% of its revenue from the RVC
segment in 1999.

Refractive Disorders

The primary function of the human eye is to focus light. The eye works
much like a camera; light rays enter the eye through the cornea, which provides
most of the focusing power. Light then travels through the lens where it is
fine-tuned to focus properly on the retina. The retina, located at the back of
the eye, acts like the film in the camera, changing light into electric impulses
that are carried by the optic nerve to the brain. To see clearly, light must be
focused precisely on the retina. The amount of refraction required to properly
focus images depends on the curvature of the cornea and the size of the eye. If
the curvature is not correct, the cornea cannot properly focus the light passing
through it onto the retina, and the viewer will see a blurred image. Refractive
disorders, such as myopia, hyperopia and astigmatism, result from an inability
of the cornea and the lens to focus images on the retina properly.

4



Laser Vision Correction Procedures

In both PRK and LASIK the physician assesses the corneal correction
required and programs the laser. Using a specially developed algorithm, the
laser's software calculates the optimal number of pulses needed to achieve the
corneal correction. Both PRK and LASIK are performed on an outpatient basis
without general anesthesia, using only topical anesthetic eye drops. The eye
drops eliminate the reflex to blink, while an eyelid holder is inserted to
prevent blinking. The patient reclines in a chair, with his or her eye focused
on a target, and the surgeon positions the patient's cornea for the procedure.
The surgeon uses a foot pedal to apply the laser beam, which emits a rapid
succession of laser pulses. The actual laser treatment takes 15 to 90 seconds to
perform and the entire procedure, from set-up to completion, takes 10 to 15
minutes.

Prostatherapy Segment Overview

- ------------------------------

In October 1997, the Company began providing thermotherapy services for
the treatment of benign prostatic hyperplasia ("BPH"). BPH is the non-cancerous
enlargement of the prostate, a condition common in men over age 60.
Thermotherapy uses microwaves to apply heat to the prostate, resulting in relief
of the symptoms of BPH without damaging surrounding tissues. Thermotherapy
relieves the symptoms of BPH without incurring the risks of complications often
associated with surgery and more invasive procedures. The Company operates three
mobile thermotherapy devices servicing hospitals and surgery centers in eastern
North Carolina and southern California. The Company is monitoring the success of
its thermotherapy operations and may expand such operations in the future. The
Company received approximately 2% of its revenues from the prostatherapy segment
in 1999.

Potential Liabilities-Insurance

- -------------------------------

All medical procedures performed in connection with the Company's
business activities are conducted directly by, or under the supervision of
physicians, who are not employees of the Company. The Company does not provide
medical services to any patients. However, patients being treated at health care
facilities at which the Company provides its non-medical services could suffer a
medical emergency resulting in serious injury or death, which could subject the
Company to the risk of lawsuits seeking substantial damages.

The Company currently maintains general and professional liability
insurance with a total limit of $1,000,000 per loss event and $3,000,000 policy
aggregate and an umbrella excess limit of $10,000,000, with a deductible of
$50,000 per occurrence. In addition, the Company requires medical professionals
who utilize its services to maintain professional liability insurance. All of
these insurance policies are subject to annual renewal by the insurer. If these
policies were to be canceled or not renewed, or failed to provide sufficient
coverage for the Company's liabilities, the Company might be forced to
self-insure against the potential liabilities referred to above. In that event,
a single incident might result in an award of damages which might have a
material adverse effect on the operations of the Company.

Government Regulation and Supervision

- -------------------------------------

The Company is subject to extensive regulation by both the federal
government and the states in which the Company conducts its business. The
Company is subject to Section 1128B of the Social Security Act (known as "the
Illegal Remuneration Statute"), which imposes civil and criminal sanctions on
persons who solicit, offer, receive or pay any remuneration, directly or
indirectly, for referring, or arranging for the referral of, a patient for
treatment that is paid for in whole or in part by Medicare, Medicaid or similar
government programs. The federal government has published regulations that
provide exceptions or a "safe harbor" for certain business transactions.
Transactions that are structured within the safe harbors are deemed not to

5



violate the Illegal Remuneration Statute. Transactions that do not satisfy all
elements of a relevant safe harbor do not necessarily violate the Illegal
Remuneration Statute, but may be subject to greater scrutiny by enforcement
agencies. The arrangements between the Company and the partnerships and other
entities in which it owns an indirect interest and through which the Company
provides most of its lithotripsy services and all of its prostatherapy services
(and the corresponding arrangements between such partnerships and other entities
and the treating physicians who own interests therein and who use the
lithotripsy and prostatherapy facilities owned by such partnerships and other
entities) could potentially be questioned under the illegal remuneration
prohibition and may not fall within the protection afforded by these safe
harbors. Many states also have laws similar to the Federal Illegal Remuneration
Statute. While failure to fall within the safe harbors may subject the Company
to scrutiny under the Illegal Remuneration Statute, such failure does not
constitute a violation of the Illegal Remuneration Statute. Nevertheless, these
illegal remuneration laws, as applied to activities and relationships similar to
those of the Company, have been subjected to limited judicial and regulatory
interpretation, and the Company has not obtained or applied for any opinion of
any regulatory or judicial authority that its business operations and
affiliations are in compliance with these laws. Therefore, no assurances can be
given that the Company's activities will be found to be in compliance with these
laws if scrutinized by such authorities.

In addition to the Illegal Remuneration Statute, Section 1877 of the
Social Security Act ("Stark II") imposes certain restrictions upon referring
physicians and providers of certain designated health services under the
Medicare, Medicaid and Champus Programs ("Government Programs"). Subject to
certain exceptions, Stark II provides that if a physician (or a family member of
a physician) has a financial relationship with an entity: (i) the physician may
not make a referral to the entity for the furnishing of designated health
services reimbursable under the Government Programs; and (ii) the entity may not
bill Government Programs, any individual or any third-party payor for designated
health services furnished pursuant to a prohibited referral under the Government
Programs. The prohibitions of Stark II only apply to the treatment of Government
Program patients, and have no application to services performed for
non-government program patients. Entities and physicians committing an act in
violation of Stark II will be required to refund amounts collected in violation
of the statute and also are subject to civil money penalties and exclusion from
the Government Programs. Physicians are investors in 51 of the Company's 65
lithotripsy operations, all of the three Company affiliates engaged in
thermotherapy services and each of the Company's six refractive vision
correction facilities. The Company lithotripsy and thermotherapy affiliates with
physician-investors are referred to herein as the "Company Physician Entities".

Many key terms in Stark II are not adequately defined and the statute
is silent regarding its application to vendors, such as the Company Physician
Entities, contracting "'under arrangements" with hospitals for the provision of
outpatient services. Prior to the publication of the Proposed Stark Regulations
described below, the Company interpreted Stark II consistently with the informal
view of the General Counsel for Health and Human Services, and concluded that
the statute did not apply to its method of conducting business. Based upon a
reasonable interpretation of Stark II, by referring a patient to a hospital
furnishing the outpatient lithotripsy or thermotherapy services "under
arrangements" with the Company Physician Entities, a physician investor in a
Company Physician Entity is not making a referral to an entity (the hospital) in
which they have an ownership interest.

On January 9, 1998, the federal government published proposed
regulations under Stark II (the "Proposed Stark Regulations"). By clarifying
certain ambiguities and defining certain statutory terms, the Proposed Stark
Regulations and accompanying commentary apply the physician referral
prohibitions of Stark II to the Company Physician Entities' practice of
contracting "under arrangements" with hospitals for treatment and billing of
Government Program patients. Only hospitals can bill the Government Programs for
lithotripsy and thermotherapy services; thus contracting under arrangements with
hospitals was the way the Company Physician Entities economically participated
in the treatment of Government Program patients. Absent a restructuring of

6



traditional operations to comply with the government's interpretation of Stark
II, the physician-investors will be prohibited from referring Government Program
patients to the hospitals contracting with the Company Physician Entities. The
Company cannot predict when final Stark II regulations will be issued or the
substance of the final regulations, but the interpretive provisions of the
Proposed Stark Regulations may be viewed as the federal government's interim
enforcement position until final regulations are issued. Restructuring
traditional operations may reduce Company revenues and limit future growth by
(i) reducing or eliminating revenues attributable to the treatment of Government
Program patients by the Company Physician Entities, (ii) reducing revenues from
the treatment of non-government patients by Company Physician Entities due to
physician, hospital and third-party payor anxiety and concern created by Stark
II, (iii) requiring the Company Physician Entities to restructure their
operations to comply with Stark II, (iv) restricting the acquisition or
development of additional lithotripsy or thermotherapy operations that will both
treat Government Program patients and have referring physician-investors, (v)
impairing the Company's relationship with urologists and (vi) otherwise
materially adversely impacting the Company.

Many states currently have laws similar to Stark II that restrict a
physician with a financial relationship with an entity from referring patients
to that entity. Often these laws contain statutory exceptions for circumstances
where the referring physician, or a member of his practice group, treats their
own patients. States also commonly require physicians to disclose to patients
their financial relationship with an entity. The Company believes that it is in
material compliance with these state laws. Nevertheless, these state
self-referral laws, as applied to activities and relationships similar to those
of the Company, have been subjected to limited judicial and regulatory
interpretation, and the Company has not obtained or applied for any opinion of
any regulatory or judicial authority that its business operations and
affiliations are in compliance with these laws. Therefore, no assurances can be
given that the Company's activities will be found to be in compliance with these
laws if scrutinized by such authorities.

In addition, upon the occurrence of changes in the law that may
adversely affect operations, the Company is required to purchase the interests
of physician-investors for certain of the Company Physician Entities. These
mandatory purchase obligations require the payment by the Company of a multiple
of earnings similar to multiples used by the Company in pricing the original
acquisition of such interests. To the extent the Company is required to purchase
such interests, such purchases might cause a default under the terms of the
Company's senior credit facility and senior subordinated notes, impair the
Company's relationship with physicians and otherwise have a material adverse
impact on the Company. Regulatory developments, such as Stark II, might also
dictate that the Company purchase all the interests of its physician-investors,
regardless of any contractual requirements to do so, or substantially alter its
business and operations to remain in compliance with applicable laws.
Accordingly, there can be no assurance that the Company will not be required to
change its business practices or its investment relationships with physicians or
that the Company will not experience a material adverse effect as a result of
any challenge made by a federal or state regulatory agency. In addition, there
can be no assurance that physician-investors who, voluntarily or otherwise,
divest of their interests in Company Physician Entities will continue to refer
patients at the same rate or at all.

Some states require approval, usually in the form of a certificate of
need ("CON"), prior to the purchase of major medical equipment exceeding a
predesignated capital expenditure threshold or for the commencement of certain
clinical health services. Such approval is generally based upon the anticipated
utilization of the service and the projected need for the service in the
relevant geographical area of the state where the service is to be provided. CON
laws differ in many respects, and not every state's CON law applies to the
Company. Most of the Company's operations originated in states which did not
require a CON for the Company's services, and the Company has obtained a CON in
states where one is required. Some states also require registration of
lithotripters with the state agency which administers its CON program. Such

7



registration is not subject to any required approval, but rather is an
administrative matter imposed so that the state will be aware of all existing
clinical health services. The Company registers in those states which require
these filings.

All states in which the Company operates require registration of the
fluoroscopic x-ray tubes which are utilized to locate the kidney stones treated
with the Company's lithotripters. The registration requirements are imposed in
order to facilitate periodic inspection of the fluoroscopic tubes.

Some states have regulations that require facilities such as mobile
lithotripters and thermotherapy facilities to be licensed and to have
appropriate emergency care resources and qualified staff meeting the stated
educational and experience criteria. The Company's lithotripsy equipment is
subject to regulation by the U.S. Food & Drug Administration, and the motor
vehicles utilized to transport the Company's mobile lithotripsy and
thermotherapy equipment are subject to safety regulation by the U.S. Department
of Transportation and the states in which the Company conducts its mobile
lithotripsy and thermotherapy business. The Company believes that it is in
material compliance with these regulations.

Except as provided herein, the Company believes it complies in all
material respects with the foregoing laws and regulations, and all other
applicable regulatory requirements; however, these laws are complex and have
been broadly construed by courts and enforcement agencies. Thus, there can be no
assurance that the Company will not be required to change its practices or its
relationships with treating physicians who are investors in the Company
Physician Entities, or that the Company will not experience material adverse
effects as a result of any investigations or enforcement actions by a federal or
state regulatory agency.

A number of proposals for healthcare reform have been made in recent
years, some of which have included radical changes in the healthcare system.
Healthcare reform could result in material changes in the financing and
regulation of the healthcare business, and the Company is unable to predict the
effect of such changes on its future operations. It is uncertain what
legislation on healthcare reform, if any, will ultimately be implemented or
whether other changes in the administration or interpretation of governmental
healthcare programs will occur. There can be no assurance that future healthcare
legislation or other changes in the administration or interpretation of
governmental healthcare programs will not have a material adverse effect on the
results of operations of the Company.

Equipment

- ---------

The Company purchases its equipment, and maintenance is generally
provided pursuant to service contracts with the manufacturer or other service
companies. The cost of a new lithotripter ranges from $400,000 to $600,000. For
mobile lithotripsy and thermotherapy, the Company either purchases or leases the
tractor, usually for a term up to five years, and purchases the trailer or a
self contained coach. The cost of the laser equipment utilized in RVC ranges
from $300,000 to $500,000. The cost of new prostatherapy equipment ranges from
$200,000 to $400,000.

Employees

- ---------

As of March 15, 2000, the Company employed approximately 301 full-time
employees and approximately 72 part-time employees.

8



Competition

- -----------

The market to provide lithotripsy services is highly fragmented and
competitive. The Company competes with other private facilities and medical
centers that offer lithotripsy services and with hospitals, clinics and
individual medical practitioners that offer conventional medical treatment for
kidney stones. Certain of the Company's current and potential competitors have
substantially greater financial resources than the Company and may compete with
the Company for acquisitions and development of operations in markets targeted
by the Company. A decrease in the purchase price of lithotripters as a result of
the development of less expensive lithotripsy equipment could decrease the
Company's competitive advantage. Most of the Company's lithotripsy services
agreements have matured past their initial terms and are now in annual renewal
terms or are on a month-to-month basis. The Company also competes with three
public companies, all of which are also manufacturers of lithotripsy equipment,
which may create different incentives for such providers in pricing lithotripsy
services. Moreover, while the Company believes that lithotripsy has emerged as
the superior treatment for kidney stone disease, the Company competes with
alternative kidney stone disease treatments.

The Company's manufacturing segment competes with at least three
privately held, national companies. The primary competitive factors are price
and quality, including product manufacturing differences. Additionally, two of
the three largest competitors are certified to provide GE trailers. The Company
believes it manufactures a high quality product at a competitive price.

The RVC market is fragmented and competitive. The Company competes with
several national, public companies as well as individual ophthalmologists,
hospitals and smaller service companies. The principal methods for competition
are pricing and quality issues. The larger competitors are primarily focused on
pricing, while the smaller competitors compete using both pricing and quality
issues. While there are lower cost competitors in the geographic areas where the
Company currently has operations, the Company believes it provides a higher
quality service for a competitive price.

ITEM 2. PROPERTIES
- ------- ----------

The Company's principal executive office is located in Austin, Texas in
an office building owned by American Physicians Service Group, Inc. ("APS"). The
Company pays APS approximately $10,000 per month, which includes rental payment
for approximately 6,700 square feet of office space, reception and telephone
services, and certain other services and facilities. The office space lease
expires in December 2002.

The Company leases approximately 11,000 square feet of office space in
Fayetteville, North Carolina under two leases expiring in 2001. The current
monthly lease amount is approximately $10,000.

The Company's manufacturing subsidiary owns a building containing
approximately 78,000 square feet of manufacturing and office space in Harvey,
Illinois.

ITEM 3. LEGAL PROCEEDINGS
- ------- -----------------

The Company is involved in various claims and legal actions that have
arisen in the ordinary course of business. Management believes that any
liabilities arising from these actions will not have a material adverse effect
on the financial condition, results of operations or cash flows of the Company.

any risks and uncertainties specifically identified in the text surrounding such
forward-looking statements, the reader should consult the Company's reports on

Year ended December 31, 1999 compared to the year ended December 31, 1998
- -------------------------------------------------------------------------

Total revenues increased $7,538,000 (7%) as compared to the same period
in 1998. Revenues from lithotripter operations decreased by $2,873,000 (3%)
primarily due to renegotiation of contracts which resulted in a larger number of
contracts providing for per diem pricing, and contracts lost due to non-renewal
and competition. Despite the lithotripsy revenue declines, lithotripsy procedure
volume was constant from 1998 to 1999, which the Company believes is indicative
of its market share preservation. Manufacturing revenue increased by $6,461,000
(58%) due to increased sales of MRI trailers as well as the Company's expansion
into manufacturing and sales of cardiac catheterization lab trailers. During
1998 the manufacturing facility became certified by GE to provide trailers for
MRI equipment. RVC revenues were $3,414,000 in 1999 and included fee revenue of
$3,004,000 and equity income of $410,000. The refractive operations were
acquired during the third quarter of 1999. Prostatherapy revenues increased
$627,000 (52%) as1999 revenues included a full year of operations for three
entities, while 1998 revenues included a full year of operations for one entity
and a partial year of operations for two entities.

Costs of services and general and administrative expenses (excluding
depreciation and amortization) increased from 38% to 40% of revenues and
increased $5,466,000 (14%) in absolute terms, compared to the same period in
1998. Cost of services associated with lithotripter operations increased
$327,000 (1%) in absolute terms and from 25% to 26% of lithotripter revenues.
Cost of services associated with manufacturing increased $3,676,000 (40%) due to
the increase in sales. Cost of services associated with RVC was $1,954,000,
which represents approximately 4 months of operations. Cost of services
associated with prostatherapy increased $482,000 due to increased operations.
Corporate expenses decreased from 5% to 4% of revenues and increased $101,000
(2%) in absolute terms, as the Company was able to successfully grow without
proportionately adding overhead.

Other deductions decreased $4,318,000 from 1998 to 1999. This decrease
is attributable to a decrease in loan fees and stock offering costs of
$4,412,000 due to costs recognized in 1998 of $4,978,000 associated with the
$100 million senior subordinated notes offering and the $50 million increase in
the senior revolving credit facility, partially offset by 1999 expenses of
$566,000 related to a restructuring of the Company's $100 million senior
revolving credit facility. Also contributing to the decrease in other deductions
was income recognition in 1999 of $1,140,000 due to the release of a contractual
obligation related to a management incentive compensation program accrued at
December 31, 1998. These decreases were partially offset by an increase in
interest expense of $939,000, primarily due to the $100 million debt offering
which closed in March 1998.

12



Minority interest in consolidated income decreased $282,000 in 1999 as
compared to 1998 primarily due to the decline in lithotripsy revenue discussed
above in certain of the Company's subsidiaries. Earnings before interest, taxes,
depreciation, and amortization (EBITDA) attributable to minority interests was
$28,554,000 for the year ended December 31, 1999 compared to $28,077,000 for the
same period in 1998. EBITDA is not intended to represent net income or cash
flows from operating activities in accordance with generally accepted accounting
principles and should not be considered a measure of the Company's profitability
or liquidity.

Income tax expense for 1999 increased $2,055,000 over 1998 primarily
due to the increase in pretax income.

Year ended December 31, 1998 compared to the year ended December 31, 1997
- -------------------------------------------------------------------------

Total revenues increased $8,657,000 (9%) as compared to the same period
in 1997. Revenues from lithotripter operations decreased by $1,060,000 (1%)
primarily due to a decline in average reimbursement per procedure. Manufacturing
revenue increased by $8,708,000 (369%) due to the fact that the 1998 revenues
were for the full year while 1997 revenues were for four months of operations.
The Company acquired the trailer manufacturer in September 1997. Prostatherapy
revenues rose $1,207,000 due to the fact that 1998 revenues were for the full
year for one entity and a partial year for another entity, while 1997 revenues
included one entity which began operations in the fourth quarter. Other revenues
decreased $198,000 primarily due to four discontinued/sold cardiac centers.

Costs of services and general and administrative expenses (excluding
depreciation and amortization) increased from 35% to 38% of revenues and
increased $6,188,000 (19%) in absolute terms, compared to the same period in
1997. Cost of services associated with lithotripter operations decreased
$2,707,000 (11%) in absolute terms and from 27% to 25% of lithotripter revenues.
Cost of services associated with manufacturing increased $7,461,000 (428%) due
to full year of operations in 1998 while 1997 costs represent four months of
operations. Cost of services associated with prostatherapy increased $803,000
due to a full year of operations for the first time in 1998. Other cost of
services decreased $229,000 (48%) primarily due to four discontinued/sold
cardiac centers. Corporate expenses decreased from 6% to 5% of revenues, as the
Company was able to successfully grow without proportionately adding overhead.
Corporate expenses decreased $757,000 (13%) primarily due to a consolidation of
corporate functions.

Other deductions increased $4,635,000 primarily due to (i) the increase
of $4,618,000 for the write-off of fees paid to lenders to obtain financing, and
(ii) an increase in interest expense of $992,000 due to an increase in new
borrowings in March 1998 related to the $100 million senior subordinated notes
offering. The increased deductions were offset partially by an increase in
interest income of $677,000.

Minority interest in consolidated income decreased $251,000 primarily
due to the decline in revenue discussed above in certain of the Company's
subsidiaries. EBITDA attributable to minority interests was $28,077,000 for the
year ended December 31, 1998 compared to $28,591,000 for the same period in
1997.

Income tax expense for 1998 increased $1,582,000 over 1997, despite the
12% reduction in pretax earnings over the same period as the 1997 provision
included the effect of a reduction in the Company's valuation allowance related
to net operating loss carryforwards.

Liquidity and Capital Resources

Cash and cash equivalents were $20,064,000 and $40,146,000 at December
31, 1999 and 1998, respectively. The Company's subsidiaries generally distribute
all of their available cash quarterly, after establishing reserves for estimated
capital expenditures and working capital. For the years ended December 31, 1999
and 1998, the Company's subsidiaries distributed cash of approximately
$27,180,000 and $25,799,000, respectively, to minority interest holders.

13



Cash provided by operations was $35,744,000 for the year ended December
31, 1999 and $45,551,000 for the year ended December 31, 1998. From 1998 to 1999
fee and other revenue collected increased by $9,602,000 and was offset by the
increase in cash paid to employees, suppliers of goods and others of
$12,396,000. These fluctuations are attributable to increased operations as well
as the timing of accounts receivable collections and accounts payable and
accrued expense payments. An increase in interest payments of $2,092,000 was due
to the $100 million of senior subordinated notes issued in March 1998, resulting
in a partial year of interest payments on this debt in 1998 versus a full year
of interest payments on this debt in 1999. Taxes paid increased $790,000 from
1998 to 1999 due to higher income tax expense during 1999. Additionally, the
Company purchased investments in a trading portfolio of $9,222,000 during 1999,
partially offset by proceeds from sales and maturities of $5,003,000.

Cash used by investing activities for the year ended December 31, 1999,
was $26,241,000 primarily due to $23,580,000 used in two refractive acquisitions
and one lithotripter acquisition as well as payments of earnouts related to
prior year acquisitions. Purchases of equipment and leasehold improvements of
$5,790,000 were partially offset by $2,352,000 in distributions from
investments. Cash used by investing activities for the year ended December 31,
1998, was $2,142,000 primarily due to $5,213,000 for the purchase of equipment
and leasehold improvements, partially offset by $2,532,000 in distributions from
investments.

Cash used in financing activities for the year ended December 31, 1999,
was $29,585,000, which was primarily due to distributions to minority interests
of $27,180,000 and purchases of treasury stock of $8,382,000 partially offset by
net borrowings of $3,181,000 and contributions of $2,636,000 received from
holders of minority interests related to expansion of existing partnerships and
new partnership formations. Cash used in financing activities for the year ended
December 31, 1998, was $27,033,000, primarily due to distributions to minority
interests of $25,799,000, purchases of treasury stock of $16,439,000 and debt
issuance costs of $4,417,000, partially offset by net borrowings of $19,541,000.

The Company's credit facility as of December 31, 1999 is comprised of a
revolving line of credit. The revolving line of credit has a borrowing limit of
$100 million, none of which was drawn at December 31, 1999 and March 15, 2000.
Subsequent to December 31, 1999 the Company completed a restructuring of its
revolving line of credit to enable the Company to draw on the revolver for RVC
acquisitions. The restructuring splits the revolver into two facilities of
$14,000,000 for refractive acquisitions by certain subsidiaries and the
remaining $86,000,000 for lithotripsy, manufacturing, refractive and
prostatherapy acquisitions as well as for working capital. On March 27, 1998,
the Company completed an offering of $100 million of senior subordinated notes
due 2008 (the "Notes") to qualified institutional buyers. The net proceeds from
the offering of approximately $96 million was used to repay all outstanding
indebtedness under the Company's bank facility, with the remainder used for
general corporate purposes, including acquisitions. In connection therewith, the
Company recorded a charge to earnings in 1998 of approximately $4.4 million for
debt issuance costs associated with the Notes. The Notes bear interest at 8.75%
and interest is payable semi-annually on April 1st and October 1st. Principal is
due April 2008.

The Company intends to increase the number of its lithotripsy
operations primarily through acquisitions and the number of its RVC operations
through both acquisitions and development. The Company intends to fund the
purchase price for future acquisitions and developments using borrowings under
its senior credit facility and cash flow from operations. In addition, the
Company may use shares of its common stock in such acquisitions where
appropriate.

14



During 1998, the Company announced a stock repurchase program of up to
$25.0 million of common stock. In February 2000 the Company announced an
increase in the authorized repurchase amount from $25.0 million to $35.0
million. From time to time, the Company may purchase additional shares of its
common stock where, in the judgment of management, market valuations of its
stock do not accurately reflect the Company's past and projected results of
operations. The Company intends to fund any such purchases using available cash,
cash flow from operations and borrowings under its senior credit facility. The
Company has purchased 2,968,800 shares of stock for a total of $25,572,000 as of
March 15, 2000.

The Company's ability to make scheduled payments of principal of, or to
pay the interest on, or to refinance, its indebtedness, or to fund planned
capital expenditures will depend on its future performance, which, to a certain
extent, is subject to general economic, financial, competitive, legislative,
regulatory and other factors that are beyond its control. Based upon the current
level of operations and anticipated cost savings and revenue growth, management
believes that cash flow from operations and available cash, together with
available borrowings under its senior credit facility, will be adequate to meet
the Company's future liquidity needs for at least the next several years.
However, there can be no assurance that the Company's business will generate
sufficient cash flow from operations, that anticipated revenue growth and
operating improvements will be realized or that future borrowings will be
available under the senior credit facility in an amount sufficient to enable the
Company to service its indebtedness or to fund its other liquidity needs.

Inflation

- ---------

The operations of the Company are not significantly affected by
inflation because the Company is not required to make large investments in fixed
assets. However, the rate of inflation will affect certain of the Company's
expenses, such as employee compensation and benefits.

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

Interest Rate Risk:
The Company has long-term debt (including current portion) totaling
$105,560,000, of which $100.8 million has a fixed rate of interest of 8.75%,
$126,000 has fixed rates of 6% to 9% and $162,000 does not bear any interest.
The remaining $4,464,000 bears interest at the prime rate. The Company is
exposed to some market risk due to the floating interest rate on the $4,464,000.
The Company makes monthly or quarterly payments of principal and interest on the
$4,464,000. An increase in interest rates of 1.5% would result in a $67,000
annual increase in interest expense on this existing principal balance.

The Board of Directors and Shareholders
Prime Medical Services, Inc.:

We have audited the accompanying consolidated financial statements of Prime
Medical Services, Inc. and subsidiaries ("Company") as listed in the
accompanying index. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Prime Medical
Services, Inc. and subsidiaries at December 31, 1999 and 1998, and the results
of their operations and their cash flows for each of the years in the three-year

PRIME MEDICAL SERVICES, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


A. ORGANIZATION AND OPERATION OF THE COMPANY

Prime Medical Services, Inc. ("Prime"), through its direct and indirect
wholly-owned subsidiaries, provides non-medical management services for
lithotripsy, refractive and prostatherapy operations. The Company
provides its services in 34 states. The Company also manufactures
trailers for major medical equipment manufacturers and mobile medical
service providers. References to the Company are to Prime and its
controlled and affiliated entities.

B. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Consolidation

The consolidated financial statements include the accounts of Prime, its
wholly-owned subsidiaries, entities more than 50% owned and partnerships where
Prime has control, even though its ownership is less than 50%. Investments in
entities in which the Company's investment is less than 50% ownership, and the
Company does not have control, are accounted for by the equity method if
ownership is between 20% - 50%, or by the cost method if ownership is less than
20%. Through December 31, 1999, the Company had recognized approximately
$675,000 in undistributed earnings using the equity method. This amount
represents undistributed earnings from entities, in which the Company owns 50%
or less, and does not exhibit control. All significant intercompany accounts and
transactions have been eliminated.

Cash Equivalents

The Company considers as cash equivalents demand deposits and all short-term
investments with an original maturity of three months or less.

Investments

The Company classifies its investments in debt securities as trading securities
in accordance with Statement of Financial Accounting Standards No. 115,
Accounting for Certain Investments in Debt and Equity Securities. Trading
securities are reported at fair value, with unrealized gains and losses included
in earnings. The change in net unrealized holding gain or loss on trading
securities for the year ended December 31, 1999 was not material.

Property and Equipment

Property and equipment are stated at cost. Major betterments are capitalized
while normal maintenance and repairs are charged to operations. Depreciation is
computed by the straight-line method using estimated useful lives of three to
ten years. Leasehold improvements are generally amortized over ten years or the
term of the lease, whichever is shorter. When assets are sold or retired, the
corresponding cost and accumulated depreciation or amortization are removed from
the related accounts and any gain or loss is credited or charged to operations.

PRIME MEDICAL SERVICES, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


B. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Intangible Assets

The Company records as goodwill the excess of the purchase price over the fair
value of the net assets associated with acquired businesses. Goodwill is
amortized using the straight-line basis over a period not to exceed twenty five
years for the refractive segment and forty years for the lithotripsy segment.
Accumulated amortization at December 31, 1999 and 1998 is $18,155,000 and
$13,807,000, respectively. Goodwill is reviewed for impairment whenever events
or changes in circumstances indicate that the carrying amount may not be
recoverable. If the sum of the expected future undiscounted cash flows is less
than the carrying amount of the goodwill, a loss is recognized for the
difference between the discounted cash flows and carrying value of the goodwill.

Revenue Recognition

Revenues generated from management services and the manufacture of trailers are
recognized as they are earned. The Company's lithotripsy fee revenues are based
upon fees charged for services to hospitals, commercial insurance carriers,
state and federal health care agencies, and individuals, net of contractual fee
reductions.

Major Customers and Credit Concentrations

A significant portion of the Company's manufacturing revenues are from four
customers. For the years ended December 31, 1999 and 1998, sales to these four
customers accounted for 71% of each year's manufacturing revenues.

Concentrations of credit risk with respect to receivables are limited due to the
wide variety of customers, as well as their dispersion across many geographic
areas. Other than as disclosed below, the Company does not consider itself to
have any significant concentrations of credit risk. At December 31, 1999,
approximately 14% of accounts receivable relate to units operating in Texas, 8%
relate to units located in Louisiana, and 12% relate to units located in
California. At December 31, 1998, approximately 17% of accounts receivable
relate to units operating in Texas, 11% relate to units located in Louisiana,
and 10% relate to units located in California.

Income Tax

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 and operating loss and tax credit carryforwards. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


B. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Long-Lived Assets

Long-lived assets are reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount may not be recoverable. If the
sum of the expected future undiscounted cash flows is less than the carrying
amount of the asset, a loss is recognized, for the difference between the fair
value and carrying value of the asset.

Accounts Receivable

Accounts receivable are recorded based on revenues, less allowance for doubtful
accounts and contractual adjustments.

Inventory

Inventory is stated at the lower of cost or market. Cost is determined using the
average cost method. Certain components that meet the Company's manufacturing
requirements are only available from a limited number of suppliers. The
inability to obtain components as required or to develop alternative sources, if
and as required in the future, could result in delays or reduction in product
shipments, which in turn could have a material adverse effect on the Company's
manufacturing business, financial condition and results of operations.

Stock-Based Compensation

Upon adoption of Statement of Financial Accounting Standards No. 123, Accounting
for Stock-Based Compensation ("Statement 123"), in 1996, the Company continued
to measure compensation expense for its stock-based employee compensation plans
using the intrinsic value method prescribed by APB Opinion No. 25, Accounting
for Stock Issued to Employees. The Company provides proforma disclosures of net
income and earnings per share as if the fair value-based method prescribed by
Statement 123 had been applied in measuring compensation expense. (See Note J).

Debt Issuance Costs

The Company expenses debt issuance costs as incurred.

Estimates Used to Prepare Financial Statements

Management uses estimates and assumptions in preparing financial statements in
accordance with generally accepted accounting principles. Those estimates and
assumptions affect the reported amounts of assets and liabilities, the
disclosure of contingent assets and liabilities, and the reported revenues and
expenses. Actual results could vary from the estimates that were assumed in
preparing the financial statements.

Reclassification

Certain reclassifications have been made to amounts presented in previous years
to be consistent with the 1999 presentation.

Earnings Per Share

Basic earnings per share is based on the weighted average shares outstanding
without any dilutive effects considered. Diluted earnings per share reflects
dilution from all contingently issuable shares, including options and warrants.
A reconciliation of such earnings per share data is as follows:

respectively, were not included in the computations of diluted EPS because the
option exercise prices were greater than the average market price of Prime's
common stock during the respective periods.

C. INVESTMENTS

Barnet Dulaney Eye Center

Effective September 1, 1999 the Company purchased a 60% interest in two laser

approximately $8,807,000 in cash and a warrant to purchase 29,000 shares of
Company common stock, plus a contingent earn-out obligation to be paid at the
end of the first year of operations after the acquisition. The contingent
earn-out obligation is based on the operating performance of one of the two
surgery centers during the first year of operations after the acquisition. This
investment is accounted for using the equity method.

Tenn-GA

In May 1997, the Company acquired a 38.25% general partner interest in a

E. FAIR VALUE OF FINANCIAL INSTRUMENTS

Statement of Financial Accounting Standards No. 107, Disclosures About Fair
Value of Financial Instruments (Statement 107), requires that the Company
disclose estimated fair values for its financial instruments as of December 31,
1999 and 1998. The carrying amounts and fair values of the Company's significant
financial instruments are as follows:

1999 1998
------------------ ------------------
Carrying Fair Carrying Fair
($in thousands) Amount Value Amount Value
------- ------- ------- -------
Financial assets:
Cash $20,064 $20,064 $40,146 $40,146

Debt 105,560 97,560 101,877 92,603
Accounts payable 3,290 3,290 5,287 5,287

The following methods and assumptions were used by the Company in estimating its
fair value disclosures for financial instruments.

Cash

The carrying amounts for cash approximate fair value because they mature in less
than 90 days and do not present unanticipated credit concerns.

Investments

The carrying value of investments approximates fair value as they are reported
based on quoted market rates.

Accounts Receivable and Other Receivables

The carrying value of these receivables approximates the fair value due to their
short-term nature and historical collectibility.

Debt

The fair value at December 31, 1999 and 1998 for the $100 million fixed rate
senior subordinated notes was valued using the market rate of 10.2% and 10.456%,
respectively. The carrying value of the debt bearing interest at prime rate
approximates fair value.

Accounts Payable

The carrying value of the payables approximates fair value due to the short-term
nature of the obligation.

PRIME MEDICAL SERVICES, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


E. FAIR VALUE OF FINANCIAL INSTRUMENTS (continued)

Limitations

Fair value estimates are made at a specific point in time, based on relevant
market information and information about the financial instrument. Fair value
estimates are based on existing on balance sheet financial instruments without
attempting to estimate the value of anticipated future business and the value of
assets and liabilities that are not considered financial instruments. Other
significant assets and liabilities that are not considered financial assets or
liabilities include deferred tax assets and liabilities, property and equipment,
equity investment in partnerships, goodwill, other noncurrent assets and accrued
expenses. In addition, the tax ramifications related to the realization of the
unrealized gains and losses can have a significant effect on fair value
estimates and have not been considered in the aforementioned estimates.

In March 1998, the Company completed an offering of an aggregate $100 million of
unsecured senior subordinated notes (the "Notes") due 2008. The issue price of
the notes was 99.50 with an 8.75% coupon. Interest is payable semi-annually on
April 1 and October 1, beginning October 1, 1998. The financing costs associated
with this offering totaling $4,418,000 were expensed during 1998 in the
accompanying consolidated statements of income. A portion of the proceeds from
the offering were used to pay off the Company's $77 million of term loans under
its existing credit facility.

The Note Indenture restricts, among other things, the ability of the Company and
its Restricted Subsidiaries to incur additional indebtedness and issue preferred
stock, enter into sale and leaseback transactions, incur liens, pay dividends or
make certain other restricted payments, apply net proceeds from certain asset
sales, enter into certain transactions with affiliates, merge or consolidate
with any other person, sell stock of subsidiaries and assign, transfer, lease,
convey or otherwise dispose of substantially all of the assets of the Company.

During 1998, the Company amended its syndicated bank facility from $135 million
to $100 million. The facility consists of a $100 million revolving credit
facility bearing interest of LIBOR + 1 to 2%, maturing in April 2003. At
December 31, 1999, the entire $100 million revolving credit facility was
undrawn. At December 31, 1999, interest on the Company's bank facility was
7.385%. The assets of the Company and the stock of its subsidiaries
collateralize the bank facility.

I. COMMITMENTS AND CONTINGENCIES

The Company is involved in various claims and legal actions that have arisen in
the ordinary course of business. Management believes that any liabilities
arising from these actions will not have a material adverse effect on the
financial condition, results of operations or cash flows of the Company.

The Company sponsors a partially, self-insured group medical insurance plan. The
plan is designed to provide a specified level of coverage, with stop-loss
coverage provided by a commercial insurer. The Company's maximum claim exposure
is limited to $35,000 per person per policy year. At December 31, 1999, the
Company had 255 employees enrolled in the plan. The plan provides
non-contributory coverage for employees and contributory coverage for
dependents. The Company's contributions totaled $966,000, $623,000 and $351,000,
in 1999, 1998 and 1997 respectively.

J. COMMON STOCK OPTIONS

1993 Stock Option Plan

The Company has elected to follow Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees" ("APB 25") and related
Interpretations in accounting for its employee stock options. The Company
provides proforma disclosures of net income and earnings per share as if the
fair-value based method prescribed by Statement 123 had been applied in
measuring compensation expense. Under APB 25, because the exercise price of the
Company's employee stock options equals the market price of the underlying stock
on the date of grant, no compensation expense is recognized.

On October 12, 1993, the Company adopted the 1993 Stock Option Plan which
authorizes the grant of up to 2,000,000 shares to certain key employees,
directors, and consultants and advisors to the Company. Options granted under
the 1993 Stock Option Plan shall terminate no later than ten years from the date
the option is granted, unless the option terminates sooner by reason of
termination of employment, disability or death.

Proforma information regarding net income and earnings per share is required by
Statement 123, and has been determined as if the Company had accounted for its
employee stock options under the fair value method of that Statement. The fair
value for these options was estimated at the date of grant using a Black-Scholes
option pricing model with the following weighted-average assumptions for 1999,
1998 and 1997, respectively: risk-free interest rates of 6.5%, 5.2% and 6.2%;
dividend yields of 0%, 0% and 0%; volatility factors of the expected market
price of the Company's common stock of .44, .42 and .46; and a weighted-average
expected life of the option of 4 years.

PRIME MEDICAL SERVICES, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


J. COMMON STOCK OPTIONS (continued)

The Black-Scholes option valuation model was developed for use in estimating the
fair value of traded options which have no vesting restrictions and are fully
transferable. In addition, option valuation models require the input of highly
subjective assumptions including the expected stock price volatility. Because
the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its employee stock options.

For purposes of proforma disclosures, the estimated fair value of the options is
amortized to expense over the options' vesting period. The Company's proforma
information follows (in thousands except for earnings per share information):

1999 1998 1997

remove from service is reported in the financial statements at the lower of
carrying amount or fair value less costs to sell. During 1999 the Company
approved the removal from service of five lithotripter units. Three of these
units were removed from service by the end of 1999 and the remaining two will be
removed from service within the first quarter of 2000. These assets are held by
the lithotripsy segment. The customers of these units are or will be serviced by
other equipment. A loss of approximately $1.1 million was recognized on the
write-down to fair value less costs to sell in the caption "nonrecurring
development, impairment and other costs, net" of the accompanying statement of
income. The minority interest portion of this loss was approximately $600,000.

L. INCOME TAXES

The Company files a consolidated tax return with its wholly owned subsidiaries.
A substantial portion of consolidated income is not taxed at the corporate level
as it represents income from partnerships. Accordingly, only the portion of
income from these partnerships attributable to the Company's ownership interests
is included in taxable income in the consolidated tax return and financial
statements. The minority interest portion of this income is the responsibility
of the individual partners.

There is no valuation allowance for deferred tax assets at December 31, 1999 and
1998. A decrease of $2,399,000 in 1997, primarily due to utilization of net
operating loss carryforwards was recorded in 1997.

In assessing the realizability of deferred tax assets, management considers
whether it is more likely than not that some portion or all of the deferred tax
assets will not be realized. The ultimate realization of deferred tax assets is
dependent upon the generation of future taxable income during the periods in
which those temporary differences become deductible. Management considers the
scheduled reversal of deferred tax liabilities, projected future taxable income,
and tax planning strategies in making this assessment.

Based upon the level of historical taxable income and projections for future
taxable income over the periods which the deductible temporary differences
reverse, management believes it is more likely than not the Company will realize
the benefits of these deductible differences at December 31, 1999.

M. RELATED PARTY TRANSACTIONS

See Note C for related party transactions involving investments in affiliates.

N. SEGMENT REPORTING

The Company has three reportable segments: lithotripsy, manufacturing and
refractive. The lithotripsy segment provides services related to the operation
of the lithotripters, including scheduling, staffing, training, quality
assurance, maintenance, regulatory compliance and contracting with payors,
hospitals and surgery centers. The manufacturing segment provides manufacturing
services and installation, upgrade, refurbishment and repair of major medical
equipment for mobile medical service providers. The refractive segment, which is
new in 1999, provides services related to the operations of refractive vision
correction centers. Other operating segments which do not meet the quantitative
thresholds for reportable segments include prostatherapy services.

A-23

PRIME MEDICAL SERVICES, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


N. SEGMENT REPORTING (continued)

The accounting policies of the segments are the same as those described in Note
B, the summary of significant accounting policies. The Company measures
performance based on the pretax income or loss after consideration of minority
interests from its operating segments, which do not include unallocated
corporate general and administrative expenses and corporate interest income and
expense. Additionally, certain consolidated entities that are reported as
"corporate" own and operate lithotripsy equipment. The revenue and depreciation
expense related to this equipment is included in the lithotripsy segment.
However, the equipment is included in corporate assets.

The Company's segments are divisions that offer different services, and require
different technology and marketing approaches. The majority of the lithotripsy
segment is comprised of acquired entities, as are the manufacturing and
refractive segments. The prostatherapy segment was developed internally. The
presentation of segments for 1998 and 1997, which included two segments for
medical and manufacturing, have been recast to conform to the Company's
operating segments for 1999.

All of the Company's revenues are earned in the United States and long-lived
assets are located in the United States. The Company does not have any major
customers who account for more than 10% of its revenues.
