PRIME MEDICAL SERVICES, INC.

ANNUAL REPORT ON FORM 10-K

FOR THE YEAR ENDED DECEMBER 31, 1996


PART I

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

Prime Medical Services, Inc., a Delaware corporation ("Prime" or the
"Company"), through its direct and indirect wholly-owned subsidiaries, provides
lithotripsy services to hospitals and provides non-medical management services
to cardiac rehabilitation centers.

The Company's predecessor corporation was organized in April 1972. The
Company maintains its principal executive office at 1301 Capital of Texas
Highway, Austin, Texas 78746, and its telephone number is (512) 328-2892.

Unless the context indicates otherwise, "Prime" or the "Company" includes
Prime and all of the other direct and indirect wholly-owned subsidiaries of
Prime on a consolidated basis.

Lithotripsy Operations
- ----------------------

The Company provides lithotripsy services through seven wholly-owned
subsidiaries: Prime Lithotripsy Services, Inc. ("Prime Lithotripsy"), Prime
Lithotripter Operations, Inc. ("Prime Lithotripter"), Ohio Litho, Inc. ("Ohio"),
R. R. Litho, Inc. ("R. R. Litho"), Texas Litho, Inc. ("Texas"), Sun Medical
Technologies, Inc. ("Sun") and Lithotripters, Inc. 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. Lithotripsy is the only
approved alternative to surgery for kidney stones. For these reasons,
lithotripsy is now the preferred treatment for kidney stones and is suitable for
the treatment of the overwhelming majority of the patients with kidney stones.

As of March 15, 1997, the Company had an economic interest in 49 mobile
lithotripters and 6 fixed site lithotripters, all but two of which are operated
by the Company. The Company's lithotripters serve hospitals and health care
facilities in 32 states. The Company provides non-medical 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, while medical care is rendered by
urologists utilizing the lithotripters.

The Company contracts for its lithotripsy services with hospitals and
surgery centers for utilization by urologists practicing at these facilities.
The Company markets to such facilities by providing well-maintained and
conveniently scheduled equipment for the use of the facility's doctors and
patients and by providing a full range of administrative and support services
that enable the facility to provide higher quality and more efficient care.

1





The Company's service agreements, which generally have terms of one to five
years, provide for the three basic types of billing arrangements described
below. In all instances, urologists who perform lithotripsy procedures bill
separately for their professional fees.

Hospital Billing Contracts - Under a hospital billing contract, the Company
bills and collects from the hospital or surgery center for lithotripsy services
provided by the Company to patients. The rates charged under these arrangements
may vary depending upon the number of procedures performed in a specific period
or category of patient. The hospital or surgery center is responsible for
billing and collecting from the patient or third-party payor directly.

True-up Contracts - Under a true-up contract, the Company bills and
collects a negotiated fee from the hospital or surgery center, which is then
retrospectively reviewed and adjusted based on the payments received by the
hospital or surgery center for the corresponding treatments. The hospital or
surgery center is responsible for billing and collecting from the patient or
third-party payor directly, which forms the basis for any true-up.

Direct Billing Contracts - Under a direct billing contract, the Company
bills the patient or the patient's third-party payor a combined fee, which
includes all aspects of the procedure, excluding the treating urologist's fee.
The Company then pays the hospital or surgery center a percentage of the
collected amount for its services.

Diagnostic Imaging Services
- ---------------------------

As of December 31, 1994, the Company had terminated its involvement in its
diagnostic operations. Prior to that, Prime Diagnostic Services, Inc. and Prime
Diagnostic Corp. of Florida, two wholly-owned subsidiaries of the Company,
provided non-medical management services to diagnostic imaging centers.

Prime Cardiac Rehabilitation Services, Inc.
- -------------------------------------------

Prime Cardiac Rehabilitation Services, Inc. ("Prime Cardiac"), a
wholly-owned subsidiary of the Company, provides non-medical management services
for six cardiac rehabilitation centers, pursuant to agreements with physicians,
clinics and hospitals ("Medical Providers") for initial terms of up to ten
years. The Medical Providers have absolute authority over the medical services
provided at the centers, fees charged to patients and the collection practices
of the facility. Prime Cardiac's fees are generally based on collected revenues
of the centers. The Company has substantially reduced its cardiac rehabilitation
business over the last three years, which accounted for less than 2% of the
Company's total revenues for the year ended December 31, 1996.

Acquisitions/Divestitures
- -------------------------

Effective May 1, 1996, the Company acquired Lithotripters, Inc. which
operates 31 lithotripters in 19 states through a network of 21 affiliated
limited partnerships. Lithotripters, Inc. has an economic interest of 20% to 58%
in each of these partnerships. Due to the significant control maintained by
Lithotripters, Inc. as provided in the partnership agreements, revenues and
expenses for the partnerships are consolidated and a minority interest
equivalent to the limited partners' aggregate ownership interest is recorded.
The purchase price was $86,500,000 consisting of $71,600,000 cash and 1,636,000
shares of the Company's common stock valued at $14,900,000.

2







Effective October 1, 1995, the Company acquired all of the outstanding
stock of Sun Medical Technologies, Inc. which operates 8 lithotripters in
California, Arizona, Montana, New Mexico, Washington and Wyoming. The purchase
price of $16,150,000 consisted of cash paid at closing equal to $9,438,000,
seven notes payable in three years with original principal amounts totaling
$4,025,000, and $2,687,000 cash paid in January, 1996. Additionally, the Company
issued warrants to purchase 200,000 shares of the Company's common stock at an
exercise price of $5.99. The notes included provisions that permit the
noteholders to convert a portion or all of the unpaid principal balance into the
common stock of the Company at $5.99 per share at each payment date. In 1996,
all of the warrants were exercised and the noteholders converted the outstanding
balances of their notes into the Company's stock.

Effective July 1, 1995, the Company acquired a 70% interest in Kidney Stone
of South Florida, L.L.C. which operates a fixed site lithotripter in the Fort
Lauderdale, Florida area. The purchase price for this interest was $3,885,000 in
cash and a promissory note with a principal amount of $1,665,000. The promissory
note included a provision that permits the noteholder to convert all of the
unpaid principal balance into common stock of the Company at the quarterly
payment dates. The noteholder converted the outstanding balance of the note into
the Company's stock in 1996.

Effective June 1, 1995, the Company acquired a 32.5% interest in Southern
California Stone Center, L.L.C., which operates a fixed-site lithotripter and a
mobile lithotripter in the Los Angeles, California area. The Company paid
$1,569,000 in cash for this interest.

Effective December 31, 1994, the Company sold substantially all of its
assets located at an imaging center in Rancho Cucamonga, California for two
promissory notes with principal amounts totaling $1,155,000 and the assumption
of certain contractual obligations.

Effective December 30, 1994, the Company sold all of its assets located at
an imaging center in Hemet, California for $260,000 in cash.

Effective December 1, 1994, the Company purchased all of the common stock
of Texas Litho, Inc., Ohio Litho, Inc. and R. R. Litho, Inc. from Maxum Health
Corp. Texas Litho, Inc. is the sole managing general partner and owns an
approximate 20% interest in Texas ESWL/Laser Lithotripter, Ltd. which operates a
mobile lithotripter in Texas, Arkansas and Oklahoma. Ohio Litho, Inc. is the
sole managing general partner and owns an approximate 21% interest in Ohio
Mobile Lithotripter, Ltd. which operates a mobile lithotripter in Ohio. R. R.
Litho, Inc. is the sole managing general partner of and owns an approximate 20%
interest in Arklatx Mobile Lithotripter Limited Partnership which operates a
mobile lithotripter in Louisiana. The purchase price paid for the common stock
was $5,007,000 in cash.

On August 31, 1994, Shasta Diagnostic Center J.V., in which the Company
owned a 50% interest, sold substantially all of the assets of Shasta Diagnostic
Center located in Redding, California. The sales price for the assets was
$450,000 in cash, a promissory note in the principal amount of $450,000, and the
assumption of certain specified liabilities.



3



Effective August 15, 1994, the Company sold substantially all of the assets
of Tower Diagnostic Center located in Tampa, Florida. The sales price for the
assets was $2,350,000 in cash, a promissory note in the principal amount of
$500,000 and the assumption of certain specified liabilities.

Effective August 1, 1994, the Company acquired substantially all of the
assets of Alabama Lithotripsy Joint Venture, an Alabama general partnership. The
partnership operated a mobile lithotripter in Alabama which it leased from
Baptist Medical Center-Montclair. In a related transaction, the Company
purchased the lithotripter for a promissory note in the principal amount of
$316,000. The purchase price for the assets of the joint venture was $2,863,000
in cash, a promissory note in the principal amount of $2,304,000, a stock
purchase warrant covering 725,000 shares of common stock of the Company
exercisable at $3.18 per share and the assumption of certain liabilities of the
joint venture. In 1996, the warrants were exercised and the note was paid off.

In July 1994, the Company purchased all of the outstanding capital stock
of Alabama Renal Stone Institute, Inc., an Alabama corporation, which operates a
fixed site lithotripter located in Birmingham, Alabama. The Company previously
operated this lithotripter through a license agreement which was canceled
concurrent with the acquisition. The purchase price for this acquisition was
$3,000,000 cash paid in 1994, along with an option issued in 1992 for 210,000
shares of the Company's common stock, and an additional payment of $895,000 in
August, 1995.

Effective April 1, 1994, the Company acquired a 60% interest in Metro
Atlanta Stonebusters, G.P., a Texas general partnership, which operates a mobile
lithotripter operating in the Atlanta, Georgia area. The purchase price for this
acquisition was $2,040,000 in cash and a promissory note issued by the Company
in an original principal amount of $3,700,000 bearing interest at 6% per year.

In January 1994, the Company acquired all of the outstanding capital stock
of Fazio Consulting, Inc. ("FCI"), a New Jersey corporation, which owns 2 mobile
lithotripters operating in Delaware, Illinois, Indiana, Maryland, Pennsylvania,
West Virginia, and Wisconsin. The purchase price for this acquisition was
$950,000 in cash, the repayment of two promissory notes of FCI in the aggregate
amount of $1,100,000 and an earnout for the next five years based on 50% of the
annual net income of FCI. In March, 1995, the Company paid an additional
$560,000 for the 1994 earnout. In January, 1996, the Company terminated the
earnout agreement for $500,000 in cash.

The Company had a 1% ownership interest in American Physicians Service
Group, Inc. ("APS") at December 31, 1995 and 1996 and a 22% interest at December
31, 1994. The Company intends to divest the remaining 1% ownership interest.

Potential Liabilities-Insurance
- -------------------------------

All medical procedures performed in connection with the Company's business
activities are conducted directly by, or under the supervision of, urologists,
cardiologists and other 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.

4



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
$25,000 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.

Governmental Regulation and Associated Risks
- --------------------------------------------

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
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 the corresponding arrangements
between such partnerships and other entities and the treating physicians who own
interests therein and who use the lithotripsy 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.

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 and
Medicaid 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 Medicare and
Medicaid programs, and (ii) the entity may not bill Medicare, Medicaid, any
individual or any third-party payor for designated health services furnished
pursuant to a prohibited referral. Entities and physicians committing an act in
violation of Stark II are subject to civil money penalties and exclusion from
the Medicare and Medicaid programs. Although lithotripsy services are not
specifically identified as a designated health service in Stark II, the
restrictions do apply to inpatient and outpatient hospital services. Lithotripsy
services provided by the Company to Medicare and Medicaid patients are billed by
the contracting hospital in its name and under its Medicare and Medicaid program
provider numbers. Therefore, while the lithotripsy services could be considered

5



inpatient/outpatient hospital services subject to the self-referral
restrictions contained in Stark II, the Company believes that the language and
legislative history of Stark II indicate that Congress did not intend for the
restrictions contained therein to apply to ownership of interests in the
partnerships and other entities through which the Company's lithotripsy services
are provided.

It is unclear whether one of the enumerated exceptions to Stark II would
apply if lithotripsy services are considered inpatient/outpatient hospital
services when billed by a hospital. A complete regulatory interpretation of
Stark II will only be available upon publication of the final Stark II
regulations. Additionally, it is unclear to what extent these regulations may
address issues regarding the Company's relationships with physician investors.
Publication of these regulations could affect the Company's relationships with
physician investors and have a materially adverse effect upon the Company.

In addition, many states have enacted similar legislation.

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 lithotripsy 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
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 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 equipment are subject to safety regulation by the U.S.
Department of Transportation and the states in which the Company conducts its
mobile lithotripsy business. The Company believes that it is in material
compliance with these regulations.


6





While the Company believes it complies in all material respects with the
foregoing laws and regulations, and all other applicable regulatory
requirements, 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 holding minority interests in partnerships and other entities through
which the Company provides most of its lithotripsy services), 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 health care reform have been made in recent
years, some of which have included radical changes in the health care system.
Health care reform could result in material changes in the financing and
regulation of the health care business, and the Company is unable to predict the
effect of such changes on its future operations. It is uncertain what
legislation on health care reform, if any, will ultimately be implemented or
whether other changes in the administration or interpretation of governmental
health care programs will occur. There can be no assurance that future health
care legislation or other changes in the administration or interpretation of
governmental health care programs will not have a material adverse effect on the
results of operations of the Company.

Equipment
- ---------

The Company purchases its lithotripter equipment and maintenance is
generally provided pursuant to service contracts with the manufacturer or local
service companies. The cost of a new lithotripter is approximately $1,200,000.
For mobile lithotripsy, 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.

Employees
- ---------

As of March 15, 1997, the Company employed approximately 250 full-time
employees and approximately 20 part-time employees.

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.

There are numerous physicians, hospitals, clinics, and other groups that
own, operate and manage cardiac rehabilitation centers. The primary competitive
factors in this industry are price, professional services offered, and the
equipment located at the facility.

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

The Company's principal executive office is located in Austin, Texas in an
office building owned by APS. The Company pays APS approximately $4,000 per
month, which includes rental payment for approximately 2,800 square feet of
office space, reception and telephone services, and certain other services and
facilities. The office space lease expires in December, 1997.

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

The Company leases approximately 5,700 square feet of office space in
Campbell, California under a five year lease which expires in 1997. The current
monthly lease amount is approximately $10,000.

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

Year ended December 31, 1996 compared to the year ended December 31, 1995
- --------------------------------------------------------------------------

Revenues
- ---------

Total revenues increased $49,209,000 (212%) as compared to the same period
in 1995. Revenues from lithotripter operations increased by $49,449,000
primarily due to the acquisition of (1) an entity that owned or managed 31
lithotripters effective May 1, 1996 (2) an entity that owned or managed 8
lithotripters effective October 1, 1995, and (3) a 70% interest in an entity
that operated one lithotripter, as of July 1, 1995. In addition, the Company
acquired a 32.5% interest in an entity that operated one lithotripter in June
1995. Revenues from cardiac centers decreased $240,000 primarily due to four
discontinued/sold cardiac centers.

Expenses
- --------

Costs and expenses decreased from 43% to 34% of revenues, but increased
$14,742,000 (147%) in absolute terms, compared to the same period in 1995. Costs
of services associated with lithotripter operations increased $13,943,000 (233%)
in absolute terms and from 27% to 28% of lithotripter revenues primarily due to
the acquisitions discussed above. Cost of services associated with cardiac
centers decreased $873,000 (58%) primarily due to four discontinued/sold cardiac
centers. Corporate expenses decreased from 11% to 6% of revenues as the Company
was able to successfully grow without proportionately adding overhead. Corporate
expenses increased $1,672,000 (65%) primarily due to the additional corporate
expenses associated with the acquisition discussed above and the management
incentive plans tied to the performance of the Company.

Other Income (Deductions)
- -------------------------

Other deductions increased $8,251,000 primarily due to (1) the write-off of
$2,735,000 in fees paid to lenders to obtain financing, and $800,000 in fees
associated with a proposed stock offering that was canceled in August, 1996, and
(2) interest expense increased $4,746,000 due to $74,000,000 in new borrowings
in 1996 primarily for the acquisition of Lithotripters, Inc. effective May 1,
1996.


Minority Interest In Consolidated Income
- ----------------------------------------

Minority interest in consolidated income increased $19,089,000 primarily
due to the minority interest associated with the 21 partnerships in which
Lithotripters, Inc. holds a controlling interest. The Company acquired all of
the stock of Lithotripters, Inc. effective May 1, 1996.



11




Year ended December 31, 1995 compared to the year ended December 31, 1994
- --------------------------------------------------------------------------

Revenues
- --------

Total revenues decreased in 1995 by $1,573,000 (6%) compared to 1994, as an
increase in revenues from lithotripsy operations was more than offset by the
Company's exit from the diagnostic imaging business. Revenues from lithotripsy
operations increased by $7,310,000 (49%) primarily due to the acquisition of 10
additional lithotripter operations in 1995 ($3,499,000) and the recognition of
revenues for a full year of operations from five lithotripter operations
acquired during 1994 ($3,942,000). Revenues from cardiac and imaging centers
declined by $8,883,000 due primarily to the Company's exit from the diagnostic
imaging business at the end of 1994.

Costs and Expenses
- ------------------

Costs and expenses in 1995 declined by $5,220,000 (34%) compared to 1994,
from 62% to 43% of revenues. Costs of services associated with lithotripsy
operations decreased from 29% to 27% of lithotripsy revenues, as the Company
recognized operating efficiencies resulting from the acquisition and
consolidation of additional lithotripsy operations. In absolute terms, these
costs increased by $1,696,000 (40%) primarily due to the acquisition of 10
additional lithotripter operations in 1995 ($1,271,000) and the full year effect
of the five lithotripsy operations acquired during 1994 ($542,000), partially
offset by a decline in costs associated with lithotripsy operations open during
both years ($117,000). Costs of services from cardiac and imaging centers
decreased by $7,075,000 (82%) primarily due to the Company's exit from the
diagnostic imaging business at the end of 1994. Corporate expenses increased by
$159,000 (7%) from 10% to 11% of total revenues primarily due to management
incentive plans tied to the performance of the Company.

Other Income/Deductions
- -----------------------

Other deductions decreased by $342,000. Interest and dividend income
decreased by $67,000 (31%) primarily due to less cash available for investment
due to cash being utilized to acquire lithotripsy operations. Interest expense
increased by $329,000 (36%) as a result of increased debt related to
acquisitions. Other income increased by $738,000 primarily due to the gain
recognized on the sale in the open market of stock of APS ($559,000), which was
being held for investment purposes.

Minority Interest In Consolidated Income
- ----------------------------------------

Minority interest in consolidated income increased $730,000 primarily due
the minority interest in a fixed site lithotripter that operated in the Fort
Lauderdale, Florida area. The Company acquired a 70% interest in this operation
effective July 1, 1995.

Liquidity and Capital Resources
- --------------------------------

The Company's cash was $20,096,000 and $4,692,000 at December 31, 1996 and
1995, respectively. Cash provided by operations for the years ended December 31,
1996 and 1995 was $40,034,000 and $10,898,000, respectively. Cash used in
investing activities for the year ended December 31, 1996 was $70,202,000. This
was primarily due to expenditures of $68,561,000 associated with acquisitions
and $2,526,000 for the purchase of equipment and leasehold improvements to be
used in the Company's operations which expenditures were partially offset by
$1,257,000 in distributions from investments. Cash provided by financing
activities for the year ended December 31, 1996 was $45,572,000 which was
primarily due to $74,000,000 of borrowings under credit facilities, partially
offset by payments in the amount of $15,351,000 on notes payable and payments to
minority interests of $13,440,000. The Company's line of credit has a borrowing
limit of $40,000,000. At December 31, 1996, $29,750,000 was drawn on the line of
credit.

The Company believes that its present cash position, together with funds
generated from operations, will provide sufficient resources to meet its cash
requirements for current operations and repay existing debt. The Company intends
to continue its growth strategy in the future and expects to facilitate
additional acquisitions through the issuance of common stock and debt financing.

The Company anticipates that capital expenditures for new and replacement
equipment in 1997 will be approximately $3,000,000, the majority of which will
be financed through operating cash flow.

Impact of Inflation
- --------------------

The assets of the Company are not significantly affected by inflation
because, having no manufacturing operations, 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.

We conducted our audits in accordance with generally accepted auditing

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, 1996 and 1995, and the results

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 to
lithotripsy and cardiac rehabilitation centers. The Company operates
lithotripters in 32 states. In December 1994, the Company sold its remaining
interest in the diagnostic imaging centers that the Company owned or managed.
(See Note E).

B. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
------------------------------------------
Consolidation
-------------

The consolidated financial statements include the accounts of the Company,
its wholly-owned subsidiaries, entities more than 50% owned and partnerships
where the Company 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 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%. 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.

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 five 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.

Investments
-----------

Effective January 1, 1996, the Company acquired a 27% general partner
interest in a partnership that provides lithotripsy service in Ohio. This
investment is accounted for using the equity method of accounting.

PRIME MEDICAL SERVICES, INC. AND SUBSIDIARIES

B. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued
-----------------------------------------------------
Investments, continued
----------------------

In November 1996, the Company acquired a 4% interest in a partnership that
operates two mobile lithotripters in North Carolina. This investment is
accounted for using the cost method of accounting.

Effective June 1, 1995, the Company acquired a 32.5% interest in a limited
liability company that operates a lithotripter facility in California. (See Note
D). This investment is accounted for using the equity method of accounting.

The Company has approximately a 1% ownership interest in the company that
is its largest stockholder. Two of the Company's eight board members are also on
the board of its largest stockholder. (See Note C). The Company's investment is
accounted for using the cost method of accounting in 1995 and 1996. In 1994, the
Company accounted for its investment using the equity method when the Company's
ownership exceeded 20%.

In December 1994, the Company acquired 100% of the stock of three
corporations, which are the managing general partners and owned an approximate
20% interest in each of three partnerships (See Note C). These investments are
accounted for using the equity method of accounting.

The Company also has an ownership interest of 50% in a joint venture that
had owned a diagnostic imaging center, which was sold in August 1994 (See Note
E). This investment is accounted for using the equity method of accounting.

Through December 31, 1996, the Company had recognized $190,000 in earnings
using the equity method. This amount represents undistributed earnings from
entities, in which the Company owns 50 percent or less, and does not exhibit
substantial control.

Intangible Assets
-----------------

The Company records as goodwill the excess of the purchase price over the
fair value of the net assets of acquired businesses. Goodwill is amortized over
a period not to exceed forty years using the straight-line basis. Accumulated
amortization at December 31, 1996 and 1995 is $5,798,000 and $2,873,000,
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 fair
value and carrying value of the goodwill.

B. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued
-----------------------------------------------------
Revenue Recognition
-------------------

Revenues generated from services are recognized as they are earned and
include, under certain contracts, the reimbursement of contractually defined
operating expenses. For the years ended December 31, 1996, 1995 and 1994, the
amounts included in revenues that were reimbursement of contractually defined
operating expenses were $58,000, $82,000 and $3,483,000, respectively.

The Company's revenues are based upon collectibility of fees for services
charged to hospitals, commercial insurance carriers and state and federal health
care agencies.

At December 31, 1996, approximately 17% of accounts receivable relate to
units operating in Texas, 11% relate to units located in California, 9% relate
to units located in Florida and 9% relate to units located in South Carolina.

Reciprocal Stockholdings
------------------------

The Company had accounted for its investment in its largest shareholder's
common stock on the equity basis prior to 1995 (see Note C). The Company's
investment was reduced for the Company's pro rata interest in the common stock
of the Company owned by such shareholder. This reduction was reflected in an
offsetting charge to reciprocal stockholdings. When the Company's investment
dropped below 5%, reciprocal stockholdings were eliminated.

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.

PRIME MEDICAL SERVICES, INC. AND SUBSIDIARIES

B. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued
------------------------------------------------------
Income Per Share
----------------

Income per share is based on the weighted average number of shares of
common stock and common stock equivalent shares outstanding during each period.
In 1995, the Company issued convertible debt, in conjunction with certain
lithotripsy acquisitions, which resulted in the computation of fully diluted
earnings per share exceeding primary earnings per share by more than 3%.

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, if there is a difference between the
fair value and carrying value of the asset.

Post Retirement/Post Employment Benefits
----------------------------------------

The Company's employee benefits do not extend beyond an employee's active
employment. Consequently, no accrual for future benefits as prescribed in
Statement of Financial Accounting Standards No. 106 and No. 112 has been
recorded.

Derivative Financial Instruments
--------------------------------

The Company has not made use of derivative financial instruments as defined
in the Financial Accounting Standards Board Statement of Financial Accounting
Standards No. 119, Disclosure about Derivative Financial Instruments and Fair
Value of Financial Instruments.

Notes Receivable
----------------

Notes receivable are recorded at cost, less allowances for doubtful
accounts when deemed necessary. The Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 114, Accounting by Creditors for
Impairment of a Loan (Statement 114), in May 1993 and the related Statement of
Financial Accounting Standards No. 118 Accounting by Creditors for Impairment of
a Loan - Income Recognition and Disclosures, in October 1994 for implementation
in fiscal years beginning after December 15, 1994. Management, considering
current information and events regarding the borrowers ability to repay their
obligations, considers a note to be impaired when it is probable that the
Company will be unable to collect all amounts due according to the contractual
terms of the note agreement. When a loan is considered to be impaired, the
amount of the impairment is measured based on the present value of expected
future cash flows discounted at the note's effective interest rate.

A-15




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


B. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, continued
-----------------------------------------------------
Notes Receivable, continued
---------------------------

Impairment losses are included in the allowance for doubtful accounts
through a charge to bad debt expense. Cash receipts on impaired notes receivable
are applied to reduce the principal amount of such notes until the principal has
been recovered and are recognized as interest income, thereafter. The adoption
of Statements 114 and 118 by the Company on January 1, 1995 did not have a
material affect on the financial statements.

Stock-Based Compensation
------------------------

The Financial Accounting Standards Board issued Statement of Financial
Accounting Standards No. 123, Accounting for Stock-Based Compensation
("Statement 123"), in October 1995 for implementation in fiscal years beginning
after December 15, 1995. Statement 123 became effective beginning with the
Company's first quarter of fiscal year 1996 and did not have a material effect
on the Company's financial position or results of operations. Upon adoption of
Statement 123, 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 K).

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 1996 presentation.

Effective July 1, 1995 the Company acquired an undivided 70% interest in a
fixed site lithotripter located in Fort Lauderdale, Florida. The purchase price
was $5,550,000 consisting of cash of $3,885,000 and notes payable of $1,665,000,
which can be converted into 326,000 shares of the Company's common stock. The
noteholder may convert all of the balance outstanding on the note on the
quarterly payment dates. (Note: The noteholder elected to convert the
outstanding balance of their note into the Company's stock in 1996.) The
acquisition was accounted for using the purchase method of accounting.

Unaudited proforma combined statement of earnings for the year ended
December 31, 1995 of the Company and the acquisitions discussed previously
assuming all were effective January 1, 1994 is as follows:

Effective August 1, 1994, the Company acquired a mobile lithotripter
operating in Birmingham, Alabama. The purchase price was cash of $2,863,000,
notes payable of $2,620,000, and a warrant to purchase approximately 725,000
shares of the Company's common stock. The exercise price of the warrant
represented the market price of the Company's common stock at the date the
warrant was issued. (Note: The noteholder exercised its warrants and in
exchange, considered the Company's $2,304,000 note paid in full, in 1996.) This
acquisition was accounted for using the purchase method of accounting.

In July 1994, the Company acquired all of the outstanding stock of Alabama
Renal Stone Institute, Inc. ("ARSI"), which owns a fixed-site lithotripter
located in Birmingham, Alabama and had previously licensed the use of the
lithotripter to a wholly-owned subsidiary of the Company. As a result, ARSI
operates the lithotripter as a wholly-owned subsidiary of the Company, free of
certain options that ARSI and its former owners had to terminate the license.
The purchase price was $3,895,000, and has been accounted for using the purchase
method of accounting.

In April 1994, the Company acquired an undivided 60% interest in certain
assets, subject to 60% of certain liabilities of Metro Atlanta Stonebusters,
Inc. ("MASI"), which operated a mobile lithotripter in the Atlanta, GA area.
Prime paid to MASI $2,040,000 in cash and a promissory note issued in the amount
of $3,700,000, bearing interest at 6%. Prime contributed its interest in the net
assets acquired to Metro Atlanta Stonebusters, G.P. ("MASBGP") in exchange for a
60% general partnership interest in MASBGP, and MASI contributed its 40%
interest to MASBGP for a 40% interest in MASBGP. This transaction was accounted
for using the purchase method of accounting.

In January 1994, the Company acquired all of the outstanding capital stock
of Fazio Consulting, Inc. ("FCI"), which operated two mobile lithotripters in
seven states. The purchase price was cash of $950,000, the repayment of two
promissory notes of FCI in the aggregate amount of $1,100,000 and an earnout for
the next five years based on 50% of the net income of FCI. At December 31, 1994,
the Company calculated the earnout for the first year to be $559,000, and that
amount has been recorded as goodwill and was accounted for using the purchase
method of accounting. At December 31, 1995, the Company reached an agreement to
settle the remaining four years of the earnout, along with a buyout of the
remaining term of two tractor leases. The Company has recorded the $700,000
settlement as follows: $685,000 recorded to goodwill and $15,000 to acquire
title to one tractor.

Accounts payable 4,451 4,451 4,814 4,814


Fair value estimates, methods, and assumptions are set forth below for the
Company's 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.

Notes Receivable
----------------

The fair value of notes has been determined using discounted cash flows
based on management's estimate of current interest rates for notes of similar
credit quality.

Accounts Receivable and Other Receivables
-----------------------------------------

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

Investment in American Physicians Service Group, Inc.
-----------------------------------------------------

The fair value of the stock is based on the last trade value at the end of
the year.

Debt
----

The carrying value of debt approximates fair value since the majority is
primarily floating rate debt based on current market rates.

Accounts Payable
----------------

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

F. 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-and-off 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 the 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.

$544,000.

The Company sponsors two partially, self-insured group medical insurance
plans. One 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, 1996,
the Company had 48 employees enrolled in the plan. The plan provides
non-contributory coverage for employees and contributory coverage for
dependents. The second plan is designed to provide a specified level of
coverage, with stop-loss coverage provided by a commercial insurer. At December
31, 1996, the Company had 150 employees enrolled in the plan. The plan provides
non-contributory coverage for employees and contributory coverage for
dependents. The Company's maximum claim exposure is limited to $20,000 per
person per policy year. The Company's contributions totaled $224,000 in 1996,
$150,000 in 1995, and $431,000 in 1994.


K. 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 because, as
discussed below, the alternative fair value accounting provided for under FASB
Statement No. 123, "Accounting for Stock-Based Compensation," requires use of
option valuation models that were not developed for use in valuing employee
stock options. 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.

Pro forma 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 1995 and 1996 option pricing model with the following
weighted-average assumptions for 1995 and 1996, respectively: risk-free interest
rates of 5.7% and 6.2%; dividend yields of 0% and 0%; volatility factors of the
expected market price of the Company's common stock of .38 and .53; and a
weighted-average expected life of the option of 4 years.

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.

M. INCOME TAXES, continued
-----------------------

The valuation allowance for deferred tax assets as of December 31, 1996 was
$2,399,000 representing a decrease of $3,093,000, primarily due to utilization
of net operating loss carryforwards. The valuation allowance for deferred tax
assets as of January 1, 1995 was $7,583,000 with the change in the total
valuation allowance for the year ended December 31, 1995 being a decrease of
$2,091,000. The Company believes that the valuation allowance at December 31,
1996 is necessary due to uncertainties regarding the Company's use of the net
operating loss carryforwards and tax credit carryforwards which could become
limited in the event that the Company experiences a greater than 50% stock
ownership change in a three-year period (as defined in the Internal Revenue
Service regulations).

At December 31, 1996, net operating loss carryforwards available to reduce
future taxable income amounted to approximately $2,777,000 and expire through
2008. Investment tax credit carryforwards, which expire through 2000, amounted
to $1,200,000 at December 31, 1996.

Based upon the level of historical taxable income and projections for
future taxable income over the periods which the deferred tax assets are
deductible, management believes it is more likely than not the Company will
realize the benefits of these deductible differences, net of the existing
valuation allowances at December 31, 1996. The amount of the deferred tax asset
considered realizable, however, could be reduced in the near term if estimates
of future taxable income during the carryforward period are reduced.

N. RELATED PARTY TRANSACTIONS
--------------------------

See Notes B and C for additional related party transactions involving
investments in affiliates.

O. SUBSEQUENT EVENT
----------------

In January 1997 the Company purchased additional ownership interests in 10
partnerships, which the Company controls. The purchase price for additional
ownership interests was $10,510,000 in cash. These transactions were accounted
for using the purchase method of accounting.
