ITEM 1.  BUSINESS
 
INTRODUCTION
 
     The Company provides "911" emergency and general transport ambulance
services, fire protection services, and other safety and health care related
services to municipal, residential, commercial, and industrial customers. The
Company believes that it is the only multi-state provider of both ambulance and
fire protection services in the United States and that it ranks as one of the
largest private-sector providers of ambulance services and fire protection
services in the world. The Company currently serves over 350 communities in 21
states, Canada, and Latin America. Ambulance services and fire protection
services accounted for approximately 81% and 13%, respectively, of the Company's
revenue for the fiscal year ended June 30, 1997.
 
     Founded in 1948, the Company has been instrumental in the development of
protocols and policies applicable to the emergency services industry. The
Company has grown significantly since the late 1970s both through internal
growth and through acquisitions. To manage this growth, the Company invested in
the development of management and operational systems that have resulted in
productivity gains and increased profitability. The Company believes its current
systems and controls position it to continue its growth internally as well as
through acquisitions and enable it to operate profitably in both large and small
communities. The Company completed eight acquisitions in the fiscal year ended
June 30, 1994, 11 acquisitions in the fiscal year ended June 30, 1995, 18
acquisitions in the fiscal year ended June 30, 1996, and 19 acquisitions in the
fiscal year ended June 30, 1997.
 
     Based on generally available industry data, it is estimated that annual
expenditures for ambulance services in the United States are between $4 billion
and $7 billion. Various factors, including the growth and aging of the
population, and trends towards the use of outpatient services and specialized
treatment facilities in an effort to contain health care costs have increased
the demand for ambulance services. At the same time, industry factors have
increased the standards of pre-hospital emergency care and have required faster
ambulance response times, increasing the capital and technological resources
necessary to provide higher levels of service. These factors, combined with the
historically fragmented nature of the ambulance service industry, are
contributing to consolidation within the industry.
 
     Market-driven forces changing the health care industry are impacting the
ambulance industry as well. The Company believes the trend toward managed care
and away from fee-for-service arrangements is furthering industry consolidation.
The move to managed care benefits larger ambulance services providers, which can
service a larger portion of a managed care provider's needs. This allows the
managed care provider to reduce its number of suppliers, cutting administrative
costs and allowing them to negotiate more favorable rates.
 
     Volunteer fire departments, tax-supported fire districts, and municipal
fire departments constitute the primary providers of fire protection services in
the United States. Because emergency medical response represents a significant
portion of fire response activity within many fire departments, the Company
believes that its ambulance and fire protection services operations are
complementary. The Company believes that its integration of such services can
provide operating economies, optimal coordination of the delivery of services,
efficiencies in the use of personnel and equipment, and enhanced levels of
service, especially in lower-utilization communities. Additionally, a variety of
economic pressures on the public sector may increase opportunities for
privatization and public/private partnerships in fire protection services.
 
     The Company pursues a strategy designed to enable it to expand its business
in existing service areas, establish additional service areas both domestically
and internationally, respond to the needs of the public sector and health care
providers, expand fire protection services, integrate existing services, and
improve productivity. This strategy includes plans to (i) acquire additional
ambulance service providers operating in metropolitan areas and in communities
surrounding the metropolitan areas that the Company currently serves or plans to
serve; (ii) expand its emergency ambulance services through the pursuit of new
contracts with municipalities and fire districts and its general ambulance
services through increased marketing efforts to, and
 
                                        1
<PAGE>   4
 
pursuit of other alliances with, managed care providers and other health care
providers; (iii) expand its fire protection services into selected additional
service areas through the pursuit of opportunities to supplant or enhance
services provided by volunteer fire departments, expand its services to newly
developed communities, and to develop public/private partnerships with tax
supported fire districts and municipal fire departments; (iv) continue the
integration of its fire protection and ambulance services to maximize
operational efficiencies and synergies; and (v) improve its productivity through
the more efficient utilization of equipment and personnel.
 
     The Company was incorporated in Arizona in 1948 and reincorporated in
Delaware in May 1993. Unless the context indicates otherwise, all references to
the "Company" refer to Rural/Metro Corporation and its subsidiaries. The Company
maintains its principal executive offices at 8401 East Indian School Road,
Scottsdale, Arizona 85251, and its telephone number is (602) 994-3886.
 
INDUSTRY CONSIDERATIONS
 
     Public-sector entities, private companies, hospitals, and volunteer
organizations provide ambulance services. Public-sector entities often serve as
the first responder to requests for such emergency ambulance services and often
provide emergency ambulance transport. When the public sector serves as first
responder, private companies often serve as the second responder and support the
first responder as needed. The private sector provides the majority of general
ambulance services. It is estimated that the ambulance service industry includes
more than 10,000 providers of service, 2,000 or more of which are private. Most
commercial providers are small companies serving one or a limited number of
markets. Several multi-state providers, including the Company, have emerged
through the acquisition and consolidation of smaller ambulance service providers
in recent years.
 
     The growth in ambulance service expenditures has resulted from both an
increase in the number of transports and an increase in the average expenditures
per transport. The growth and aging of the population, the greater use of
outpatient care facilities and home care in response to health care cost
containment efforts, and increased patient travel between specialized treatment
health care facilities have increased the demand for emergency medical services
and general ambulance services. The increased availability of "911" emergency
service, the impact of educational programs on its use, and the practice of some
members of the population of utilizing a hospital's emergency room as the source
of their primary medical care also have increased the number of ambulance
transports. Industry considerations require ambulance service providers to
acquire more sophisticated emergency medical, dispatch, and communications
equipment, hire more highly trained personnel, and develop more sophisticated
dispatch and management systems to satisfy the faster response time and higher
quality of medical care assurance criteria required by municipalities and fire
districts for emergency ambulance services. Average expenditures per ambulance
transport have increased as a result of the additional costs to meet these
requirements. These requirements, combined with the fragmented nature of the
industry, are contributing to consolidation within the industry. Service
providers that do not have the financial or management resources to meet the
requirements for higher levels of service are candidates for acquisition.
 
     Market reform continues to reshape the health care delivery system, with a
shift from fee-for-service providers to managed care providers. Managed care
providers are focusing on cost containment measures while seeking to provide the
most appropriate level of service at the most appropriate treatment facility.
While ambulances typically transport patients to the nearest treatment facility,
managed care providers are attempting to manage hospital utilization by working
with ambulance service providers to ensure transport of patients to affiliated
facilities and avoid unnecessary inter-facility transports. For non-life
threatening medical emergencies, managed care providers are beginning to explore
programs where plan members are encouraged to call the provider. Under this
program, a nurse will answer the call, analyze the medical situation, and
determine the best course of action and mode of transport. In an emergency
situation, an advanced life support ambulance will be dispatched. In certain
cases, patients could receive the required treatment level with a less costly
basic life support ambulance. However, to manage such a system, the managed care
provider must contract with an ambulance service provider that has the mix of
vehicles and geographic scope to cover the entire region served by the managed
care provider and can provide call center services.

     Based on the Company's experience, the Company believes that its ambulance
and fire protection services are complementary. Municipal fire departments,
tax-supported fire districts, and volunteer fire departments constitute the
principal providers of fire protection services in the United States. In most of
the communities served by municipal fire departments and tax-supported fire
districts, the fire department is the first to respond to a call for emergency
medical services. Approximately 27,000 volunteer fire departments, covering
approximately 40% of the United States population, operate throughout the United
States. Volunteer fire departments range from departments comprised entirely of
volunteer personnel to departments that utilize one or more paid personnel
located at each station supplemented by volunteers who proceed directly to the
fire scene. In addition to providing fire protection services to municipalities
and tax-supported fire districts, the private sector also provides fire
protection services to industrial complexes, including airports, large
industrial and petrochemical plants, power plants, and other large
self-contained facilities.
 
STRATEGY
 
     The Company's strategy is to enhance its position as a leading provider of
emergency services in the United States and in other countries. Key elements of
this strategy include the acquisition of ambulance service providers, increased
marketing efforts aimed at the needs of the public sector and health care
providers, expansion of fire protection services, integration of ambulance and
fire protection operations, and improved productivity. The Company seeks to
utilize key business competencies in communications and in logistics management
to expand service offerings to customers and to seek new potential customers
through key business alliances, joint ventures, or other strategic business
arrangements.
 
     Acquisition of Ambulance Service Providers
 
     The Company seeks acquisitions that enable it to establish new service
areas both domestically and internationally and acquisitions that enable it to
expand its operations within its existing service areas. The Company believes
that the fragmented nature of the industry, combined with the lack of capital
and limited management systems that characterize many providers, continues to
provide an opportunity for the Company to acquire additional ambulance service
providers, including not-for-profit hospital-owned providers, that would benefit
from its management and operational systems, resulting in productivity gains and
enhanced levels of service.
 
     The Company considers a number of factors in evaluating a proposed
acquisition candidate, including the quality of its management and medical
personnel, its historical operating results and future earnings potential, the
size and anticipated growth of its market, its relative position within that
market, and the competition to be encountered in such market. The Company pays
special attention to those potential service areas in which it can achieve
maximum productivity by achieving market leadership over a regional area, by
utilizing its ambulances to provide both "911" emergency and general ambulance
services, and by integrating ambulance services with fire protection services.
The Company continues to build its regional operations, which better position
the Company to serve the developing managed care customer base.
 
     Increased Marketing Efforts Aimed at the Needs of the Public Sector and
Health Care Providers
 
     In addition to expansion through acquisitions, the Company plans to expand
its general ambulance services through increased marketing efforts to hospitals,
health maintenance organizations, and other health care providers and its
emergency ambulance services through the pursuit of new contracts and alliances
with municipalities and fire districts. These efforts will focus on the
increased demand for emergency ambulance services caused by various factors,
including the growth and aging of the population, as well as on the increased
use of general ambulance services caused in part by increases in home health
care, patient travel between specialized health care facilities, and increased
requirements for transport to specific facilities operated by managed care
providers. The Company intends to respond to the needs of managed care providers
by delivering high quality, efficient, cost-effective services and the ability
to transport patients to the most appropriate treatment facility, particularly
in those geographic areas in which it has been able to achieve market
leadership. The Company intends to develop and offer innovative value-added
services to health care providers, such as access to a medical call center, to
better serve the demand management, telephone triage,
 
                                        3
<PAGE>   6
 
and medical transport needs of the managed care market. The Company believes
that its communications and logistics expertise will enable it to offer services
that will improve the responsiveness and cost-effectiveness of health care
services in a managed care environment. The Company expects to pursue alliances
with health care providers through the pursuit of service contracts, the
development of relationships, and through acquisitions of health care and safety
related providers, which would provide opportunities for the Company to
integrate its services with such other service providers. In addition, the
Company will continue to seek to enter into public/private alliances to compete
for new business.
 
     Expansion of Fire Protection Services
 
     The Company plans to continue its efforts to expand its fire protection
services into areas not currently served. In seeking to expand its fire
protection services, the Company plans to emphasize the benefits of its services
in terms of lower per capita fire service costs, reduced insurance rates, and
lower loss of life and property resulting from its extensive experience, its
fire prevention initiatives, its management and operational systems, and its
system utilizing full-time fire fighters and part-time reservists. The Company's
strategy includes efforts to provide service to businesses and residences in
newly developed communities that have not yet arranged for fire protection
services as well as in areas served by volunteer fire departments and tax-
supported fire districts. The Company plans to respond to the economic pressures
on the public sector to reduce taxes and expenditures for emergency services by
offering the opportunity for the establishment of public/private alliances with
fire districts and municipalities. The Company also intends to pursue
opportunities to provide fire protection services to large industrial complexes,
including airports, large industrial and petrochemical plants, power plants, and
other self-contained facilities.
 
     Integration of Ambulance and Fire Protection Services
 
     Building upon the Company's successful integration of ambulance and fire
services under its contract with the City of Scottsdale, the Company plans to
continue the integration of its fire and ambulance services in certain of its
service areas and to pursue opportunities to provide integrated services in new
service areas. The Company believes that its integration of such services can
provide operating economies, optimal coordination of the delivery of services,
efficiencies in the use of personnel and equipment, and enhanced levels of
service, especially in lower-utilization communities.
 
     Productivity Improvement and Enhancement
 
     The Company intends to utilize its management and operational systems to
achieve enhanced productivity and profitability in its existing operations and
in acquired operations. The centralization of key management and operating
systems permits the Company to achieve economies of scale at both the
operational and corporate levels.
 
     The Company believes that the achievement of its goal of establishing
market leadership in its various service areas (through initial acquisitions,
follow-on acquisitions, alliances, and internal growth) will enable it to
continue to improve its productivity in those areas by enabling it to more
efficiently utilize its equipment and personnel, to better serve large regional
health care providers, and to more effectively market its services. In certain
cases, follow-on acquisitions in existing service areas enable the Company to
enhance its productivity in that service area to an extent greater than the size
of the acquisition itself.

under the names Rural/Metro Ambulance and Rural/Metro Medical Services and under
the name Southwest Ambulance in some areas of Arizona. The Company may operate
under other names depending upon local statutes or contractual agreements. The
Company generally provides its ambulance services pursuant to a contract or
certificate of necessity on an exclusive or nonexclusive basis. It provides
"911" emergency ambulance services primarily pursuant to contracts or as a
result of providing fire protection services. Ambulance service contracts in
some service areas provide for the payment of a subsidy to the Company.
 
     In some service areas, the Company is the only provider of both emergency
and general ambulance services. In other service areas, the Company competes for
general ambulance services. In all service areas, the Company responds to "911"
emergency calls if requested by a municipality or fire district, even in the
absence of a contract.
 
     The Company provides fire protection services under the name Rural/Metro
Fire Department in six states and in Latin America. Fire protection services are
provided pursuant to master contracts or on a subscription basis.
 
AMBULANCE SERVICES
 
Emergency Medical Services
 
     The Company generally provides emergency medical ambulance services
pursuant to contracts with counties, fire districts, and municipalities. These
contracts typically appoint the Company as the exclusive provider of "911"
emergency ambulance services in designated service areas and require the Company
to respond to every "911" emergency medical call in those areas. The Company
responds to virtually all "911" calls with advanced life support ("ALS")
ambulance units. The Company staffs its ALS ambulance units with two paramedics
or one paramedic and an emergency medical technician ("EMT") and equips such
units with ALS equipment (such as cardiac monitors, defibrillators, and oxygen
delivery systems) as well as pharmaceuticals and medical supplies.
 
     Upon arrival at an emergency, the ALS crew members deploy portable life
support equipment, ascertain the patient's medical condition and, if required,
begin life support techniques and procedures that may include airway intubation,
cardiac monitoring, defibrillation of cardiac arrhythmias, and the
administration of medications and intravenous solutions. The crew also may
perform basic life support ("BLS") services which include basic airway
management, hemorrhage control, stabilization of fractures, emergency
childbirth, and basic vehicle extrication. As soon as medically appropriate, the
patient is placed on a portable gurney and carried into the ambulance. While a
paramedic monitors and treats the patient, the other crew member drives the
ambulance to a hospital designated either by the patient or the applicable
medical protocol. En route, the ALS crew alerts the hospital regarding the
patient's medical condition, and if necessary, the attending paramedic seeks
advice from a hospital emergency room physician as to treatment. Upon arrival at
the hospital, the patient generally is taken to the emergency room.
 
                                        5

General Ambulance Services
 
     The Company provides general ambulance services to patients requiring
either advanced or basic levels of medical supervision during transfer to and
from residences and health care facilities. These services may be provided when
a home-bound patient requires examination or treatment at a health care facility
or when a hospital inpatient requires tests or treatments (such as MRI testing,
CAT scans, dialysis, or chemotherapy treatment) available at another facility.
The Company utilizes ALS or BLS ambulance units to provide general ambulance
services depending on the patient's needs and the proximity of available units.
The Company staffs its BLS ambulance units with two EMTs and equips such units
with medical supplies and equipment necessary to administer first aid and basic
medical treatment.
 
     The Company also provides critical care transport services to medically
unstable patients (such as cardiac patients and neonatal patients) who require
critical care while being transported between health care facilities. Critical
care services differ from ALS services in that the ambulance may be equipped
with additional medical equipment and may be staffed by a medical specialist
provided by the Company or by a health care facility to attend to a patient's
special medical needs.
 
     In addition to ambulance services, the Company provides non-medical
transportation for the handicapped and certain non-ambulatory persons in certain
service areas. Such transportation generally takes place between residences or
nursing homes and hospitals or other health care facilities. In providing this
service, the Company utilizes vans that contain hydraulic wheelchair lifts or
ramps operated by drivers who generally are trained in cardiopulmonary
resuscitation ("CPR").
 
     The Company provides general ambulance services, critical care transports,
and nonmedical transportation services pursuant to contracts with governmental
agencies, health care facilities, or at the request of a patient. Such services
may be scheduled in advance or provided on an as needed basis. Contracts with
managed care providers provide for reimbursement on a per transport basis or on
a "capitated" basis under which the Company receives a fixed fee per person per
month. The Company currently has a contract to provide non-emergency ambulance
transportation for Aetna Health Plan of Ohio's 550,000 managed care plan members
on a fee-for-service basis. The contract may evolve into a capitated format
after the service utilization patterns are firmly established.
 
Medical Personnel and Quality Assurance
 
     Paramedics and EMTs must be state certified in order to transport patients
and to perform emergency care services. Certification as an EMT requires
completion of a minimum of 164 hours of training in a program designated by the
United States Department of Transportation and supervised by state authorities.
EMTs also may complete advanced training courses to become certified to provide
certain additional emergency care services, such as administration of
intravenous fluids and advanced airway management. In addition to completion of
the EMT training program, the certification as a paramedic requires the
completion of more than 800 hours of training in advanced patient care
assessment, pharmacology, cardiology, and clinical and field skills. Many of the
paramedics currently employed by the Company served as EMTs for the Company
prior to their certification as paramedics.
 
     Local physician advisory boards develop medical protocols to be followed by
paramedics and EMTs in a service area. In addition, instructions are conveyed on
a case-by-case basis through direct communications between the ambulance crew
and hospital emergency room physicians during the administration of advanced
life support procedures. Both paramedics and EMTs must complete continuing
education programs and, in some cases, state supervised refresher training
examinations to maintain their certifications. Certification and continuing
education requirements for paramedics and EMTs vary among states and counties.
 
     The Company maintains a commitment to provide high quality pre-hospital
emergency medical care. In each location in which the Company provides services,
a medical director, who usually is a physician associated with a hospital the
Company serves, monitors adherence to medical protocol and conducts periodic
audits of the care provided. In addition, the Company holds retrospective care
audits with its employees to evaluate compliance with medical and performance
standards.
 
                                        6
<PAGE>   9
 
     The Company was one of the first ambulance service providers to obtain
accreditation for many of its larger ambulance operations from the Commission on
Accreditation of Ambulance Services, a joint program between the American
Ambulance Association and the American College of Emergency Physicians. The
process is voluntary and evaluates numerous qualitative factors in the delivery
of services. The Company believes municipalities and managed care providers will
consider accreditation as one of the criteria in awarding contracts in the
future.
 
FIRE PROTECTION SERVICES
 
     Fire protection services consist primarily of fire prevention and fire
suppression. Other fire protection related activities include hazardous material
containment, underwater search and recovery, mountain and confined space rescue,
and public education. The Company provides various levels of fire protection
services ranging from fire stations that are fully staffed 24 hours per day to
reserve stations. The Company generally provides its services to municipalities
and other governmental bodies pursuant to master contracts and to residences,
commercial establishments, and industrial complexes pursuant to subscription fee
and other fee-for-service arrangements. Federal and state governments contract
with the Company from time to time to suppress forest fires or wildfires on
government lands.
 
     The Company has placed fire prevention and education in the forefront of
its fire protection services and has developed a comprehensive program to
prevent and minimize fires rather than emphasizing a standing army to respond to
fires that occur. The Company believes that effective fire protection requires
the intensive training of personnel, the effective utilization of fire
equipment, the establishment of effective communication centers for the receipt
of emergency calls and the dispatch of equipment and personnel, the
establishment and enforcement of strict fire codes, and community educational
efforts.
 
     The Company seeks to provide quality fire protection services at reduced
costs. The Company believes that it provides fire protection services at a cost
significantly lower than the national average as a result of its emphasis on
fire prevention, its advanced systems, and its use of a combination of full-time
fire fighters and part-time reservists. Based upon generally available industry
data, the Company believes that fire loss per capita in the areas serviced by
the Company has been substantially less than the national average.
 
Fire Protection Personnel
 
     The Company's ability to provide its fire protection services at relatively
low costs results from its efficient use of personnel in addition to its fire
prevention efforts. Typically, personnel costs represent more than two-thirds of
the cost of providing fire protection services. The Company has been able to
reduce its labor costs through a system that utilizes full-time firefighters
complemented by paid part-time reservists as well as a modified every other day
shift schedule. By using trained reservists on an as needed basis, the Company
has the ability to supplement full-time fire fighters on a cost-effective basis.
Reservists comprise approximately 45% of the Company's operational work force.
 
     All full-time and reservist firefighters undergo extensive training, which
exceed the standards recommended by the National Fire Protection Association
("NFPA"), and must qualify for state certification before being eligible for
full-time employment by the Company. Since approximately 70% to 80% of the
Company's fire response activity consists of emergency medical response, all of
the Company's firefighters are trained EMTs and an increasing number of its
firefighters are paramedics. Ongoing training includes instruction in new fire
service tactics and fire fighting techniques as well as continual physical
conditioning.
 
Fire Response
 
     An alarm typically results in the dispatch of one or more engine companies
(each of which consists of an engine and two to four firefighters, including a
captain), a fire chief, and such other equipment as circumstances warrant. The
amount of equipment and personnel depends upon the type, location, and severity
of the incident. The Company generally responds to emergency medical calls and
small fires (such as grass or dumpster fires not involving the risk of
spreading) with a single engine staffed by two firefighters. The
 
                                        7
<PAGE>   10
 
Company utilizes its dispatch capabilities to reposition equipment and
firefighters to maximize the availability and use of resources in a
cost-effective manner.
 
Fire Prevention
 
     The Company believes that fire prevention programs result in both lower
fire loss and significant overall cost savings. The Company's fire prevention
programs include advice and recommendations for and the encouragement of various
fire prevention methods, including fire code design, building design to inhibit
the spread of fire, the design of automatic fire suppression sprinklers, fire
detector and smoke detector installations, the design of monitoring and alarm
systems, the placement and inspection of fire hydrants, fire code inspection and
enforcement, and the determination of fire cause and origin in arson suspected
fires. In addition, the Company's personnel perform community education programs
designed to reduce the risk of fire and increase the Company's community
profile.
 
     The Company believes that its long standing public/private relationship
with the City of Scottsdale provides an example of an effective, cost-efficient
fire protection program. The Scottsdale program emphasizes the Company's
philosophy of fire prevention. With the cooperation and assistance of the
Company, the City of Scottsdale has designed comprehensive fire prevention
measures, including fire codes, inspections, and sprinkler and smoke detector
ordinances. The Company believes that as a result of strict fire codes, the
enactment of a sprinkler ordinance, and the effectiveness of the services
provided by the Company, Scottsdale's per capita cost for fire protection is 46%
lower than the national average and that its per capita fire loss is more than
200% less than the national average.
 
INDUSTRIAL FIRE PROTECTION SERVICES
 
     The Company continues to seek opportunities to provide fire protection
services to large industrial complexes, such as airports, large industrial and
petrochemical plants, power plants, and other self-contained facilities. During
1996, the Company signed a three-year contract to provide firefighting and
hazardous materials response services to the Heath-Newark-Licking County Airport
Authority, located outside Columbus, Ohio and a four-year contract to provide
crash/rescue firefighting services at the Lafayette Regional Airport in
Lafayette, Louisiana. In 1997, the Company entered into a five-year contract to
provide crash/rescue firefighting services to three airports in Bolivia. The
Company intends to pursue similar contracts domestically and internationally.
 
FIRE TRAINING SERVICES AND PROTECTION SERVICES
 
     The Company has instituted industrial fire training services and protection
services and provides sophisticated training for industrial, professional, and
specialized firefighters using live burn training to simulate realistic
firefighting situations. The training permits fire brigade and emergency
response teams to meet increased federal training requirements, the Occupational
Safety and Health Act ("OSHA"), and other regulatory requirements for work place
safety and on-site response teams.
 
     The Company anticipates that its training services to industrial,
petrochemical, and other large private concerns will enhance its ability to
enter into contractual relationships to provide fire protection, security, and
other safety related services to these concerns and permit the complexes to
replace their fire brigades with professional firefighters and emergency
response teams. These activities have not resulted in significant revenue to
date. The combination of fire protection services with security services in
large industrial complexes has the potential to provide for greater efficiency
and utilization in the delivery of such services and to result in greatly
reduced cost to the industrial complexes for such services.
 
     The Company utilizes its communications centers for home security, home
fire alarm monitoring and personal emergency response systems monitoring to
complement the emergency services it offers. The Company believes protection
services can be integrated with fire protection and ambulance services for
optimal efficiency and maximum cost-effectiveness. In August 1997, the Company
commenced a five-year contract to monitor global positioning satellite tracking
systems in vehicles.
 
                                        8

MANAGEMENT SYSTEMS
 
     The Company utilizes sophisticated management systems, which it believes
enhance the productivity and profitability of the Company's existing operations
and enable it to enhance the productivity and profitability of acquired
operations. These systems permit the Company to achieve economies of scale at
the local operational level through the proper utilization of personnel and
equipment and at the corporate level through centralized systems for billings,
collections, purchasing, accounting, cash management, human resources, risk
management, and third-party reimbursement.
 
     The Company has developed measurement systems that permit management to
monitor the performance level of each operation on a continual basis. The
Company's centralized management and information systems permit managers to
direct their attention primarily to operations. The systems include centralized
billings and collections procedures that provide for more efficient tracking and
collection of accounts receivable. Centralized purchasing permits the Company to
achieve significant discounts in the purchase of equipment and supplies through
a Company-developed catalogue from which managers select items needed for their
operations. Centralized third-party reimbursement allows the Company to maximize
the utilization of its expertise in Medicare, Medicaid, and other third-party
payor reimbursement programs and to ensure the most favorable classification for
all of the Company's operations under such programs.
 
     The Company believes its investment in management systems and its effective
use of such systems represent key components in its success. The Company's
financial reporting system facilitates the Company's successful integration of
acquired companies. The Company is committed to an ongoing enhancement of its
systems to provide productive, timely information, and effective controls and
believes that its management systems have the capability to support sustained
long-term growth.
 
HUMAN RESOURCES
 
     The Company strives to maximize the operational autonomy of its managers.
Managers receive extensive training in the use of management systems, customer
service, and supervisory practices. The Company's centralized human resources
division increases the Company's ability to assign the most appropriate
personnel for a position within any given operation and to reassign personnel as
necessary to meet operational needs. The human resources department participates
in all areas of training, career development, and succession planning of
employees and assesses the Company's personnel needs.
 
DISPATCH AND COMMUNICATIONS
 
     The Company uses system status plans and flexible deployment systems to
position its ambulances within a designated service area because effective fleet
deployment represents a key factor in reducing response time and increasing
efficient use of resources. In certain service areas with a large volume of
calls, the Company analyzes data on traffic patterns, demographics, usage
frequency, and similar factors with the aid of computers to help it determine
optimal ambulance deployment and selection. The center that controls the
deployment and dispatch of ambulances in response to calls for ambulance service
may be owned and operated either by the applicable county or municipality or by
the Company itself. Each control center utilizes computer hardware and software
and sophisticated communications equipment and maintains responsibility for
fleet deployment and utilization 24 hours a day, seven days a week.
 
     Depending on the emergency medical dispatch system used in a designated
service area, the public authority that receives "911" emergency medical calls
either dispatches the Company's ambulances directly from the public control
center or communicates information regarding the location and type of medical
emergency to the Company's control center which in turn dispatches ambulances to
the scene. In most service areas, the Company's control center receives the
calls from the police after the police have determined the call is for emergency
medical services. When the Company receives the "911" call, it dispatches one or
more ambulances directly from its control center while the call taker
communicates with the caller. All call takers and dispatchers are trained EMTs
with additional training that enables them to instruct a caller about applicable
pre-arrival emergency medical procedures, if necessary. In the Company's larger
control centers, a computer assists the dispatcher by analyzing a number of
factors, such as time of day, ambulance location, and
 
                                        9
<PAGE>   12
 
historical traffic patterns, in order to recommend optimal ambulance selection.
In all cases, a dispatcher selects and dispatches the ambulance. While the
ambulance is en route to the scene, the ambulance receives information
concerning the patient's condition prior to the ambulance's arrival at the
scene.
 
     The Company's communication systems allow the ambulance crew to communicate
directly with the destination hospital to alert hospital medical personnel of
the arrival of the patient and the patient's condition and to receive
instructions directly from emergency room personnel on specific pre-hospital
medical treatment. These systems also facilitate close and direct coordination
with other emergency service providers, such as the appropriate police and fire
departments, that also may be responding to a call.
 
     Deployment and dispatch also represent important factors in providing
non-emergency ambulance services. The Company implements system status plans for
these services designed to assure appropriate response times to non-emergency
calls. The Company intends to establish call centers that will enable it to
implement demand management strategies for health care providers. Through its
strategic alliance with National Health Enhancement Systems, Inc., the Company
is working to develop a demand management system that integrates medical
protocols with the Company's logistics and "911" based communications expertise.
By combining telephone triage and medical transport services, the Company can
improve the responsiveness and cost-effectiveness of health care delivery in a
managed care system. Managed care providers could encourage their plan members
to contact a call center in non-life threatening emergencies. The call centers
are staffed by nurses who use medical protocols to analyze and triage the
medical situation and determine the best mode of transport. In non-emergency
situations, the call centers could dispatch a BLS ambulance rather than a more
expensive ALS ambulance. The call center can also direct the ambulance to
transport the patient to an affiliated facility specified by the managed care
center rather than to a non-member facility or a hospital emergency room,
thereby further reducing costs for the provider.
 
     The Company utilizes communication centers in its fire protection
activities for the receipt of fire alarms and the dispatch of equipment and
personnel that are the same as or similar to those maintained for its ambulance
services. Response time represents an important criteria in the effectiveness of
fire suppression. Depending upon the area served, the Company's response time
from the receipt of a call to the arrival on the scene generally varies from 4
to 15 minutes. Response times depend on the level of protection sought by the
Company's customers in terms of fire station spacing, the size of the service
area covered, and the amount of equipment and personnel dedicated to fire
protection.
 
BILLINGS AND COLLECTIONS
 
     The Company currently maintains 13 billing and payment processing centers
and a centralized billing and collection system at its headquarters in Arizona.
Invoices are generated at the regional level, and the account is processed by
the centralized system only if payment is not received in a timely manner.
Customer service is directed from each of the regional centers.
 
     The Company derives a substantial portion of its ambulance fee collections
from reimbursement by third-party payors, including payments under Medicare,
Medicaid, and private insurance programs, typically invoicing and collecting
payments directly to and from those third-party payors. The Company also
collects payments directly from patients, including payments under deductible
and co-insurance provisions and otherwise. During fiscal 1995, 1996, and 1997,
the Company derived approximately 33%, 27%, and 26%, respectively, of its net
ambulance fee collections from Medicare, 12%, 11%, and 10%, respectively, from
Medicaid, 40%, 41%, and 38%, respectively, from private insurers (including
prepaid health plans and other non-government sources), and 15%, 21%, and 26%,
respectively, directly from patients. Companies in the ambulance service
industry maintain high provisions for doubtful accounts relative to companies in
other industries. Collection of complete and accurate patient billing
information during an emergency service call is sometimes difficult, and
incomplete information hinders post-service collection efforts. In addition, it
is not possible for the Company to evaluate the creditworthiness of patients
requiring emergency transport services. The Company's allowance for doubtful
accounts generally is higher with respect to revenue derived directly from
patients than for revenue derived from third-party payors and generally is
higher for transports resulting from "911" emergency calls than for general
transport requests.
 
                                       10
<PAGE>   13
 
     The Company has substantial experience in processing claims to third-party
payors and employs a collection staff specifically trained in third-party
coverage and reimbursement procedures. The Company uses specialized proprietary
software systems to specifically tailor the submission of claims to Medicare,
Medicaid, and certain other third-party payors and has the capability to
electronically submit claims to the extent third-party payors systems permit.
The Company's systems provide for accurate tracking of accounts receivable and
status pending payment, which facilitates the effective utilization of personnel
resources to resolve workload distribution and problem invoices. The Company
uses an automated dialer that preselects and dials accounts based on their
status within the billing and collection cycle, which optimizes the efficiency
of the collection staff. The Company believes that its experience in processing
third-party claims reduces the collection time of its receivables and results in
fewer rejected claims based on incomplete or inaccurate information.
 
     State licensing requirements as well as contracts with counties,
municipalities, and health care facilities typically require the Company to
provide ambulance services without regard to a patient's insurance coverage or
ability to pay. As a result, the Company often does not receive compensation for
services provided to patients who are not covered by Medicare, Medicaid, or
private insurance. The anticipated level of uncompensated care and allowance for
uncollectible accounts may be considered in determining the Company's subsidy
and permitted rates under contracts with a county or municipality.
 
MARKETING AND SALES
 
     Counties, fire districts, and municipalities generally award contracts to
provide "911" emergency services either through requests for competitive
proposals or bidding processes. In some instances in which the Company is the
existing provider, the county or municipality may elect to renegotiate the
Company's existing contract rather than re-bid the contract. The Company
believes that counties, fire districts, and municipalities consider the quality
of care, historical response time performance, and total cost, both to the
municipality or county and to the public, to be the most important factors in
awarding contracts. In addition, the Company will continue to seek to enter into
public/private alliances to compete for new business. The Company's alliance
with San Diego Fire & Life Safety Services allowed the entities to bid for and
win a contract to provide "911" and ambulance services throughout the city of
San Diego.
 
     The Company markets its non-emergency ambulance services to hospitals,
health maintenance organizations, convalescent homes, and other health care
facilities that require a stable and reliable source of medical transportation
for their patients. The Company believes that its status as a "911" provider in
a designated service area increases its visibility and enhances its marketing
efforts for non-emergency services in that area. Contracts for non-emergency
services usually are based on criteria (such as quality of care, customer
service, response time, and cost) similar to those in contracts for emergency
services. The Company further believes that its strategy of building regional
operations will better position it to serve the developing managed care market.
The Company has implemented customer service training for all its personnel in
recognition of the increasing awareness of managed care providers to the
importance of customer service.
 
     The Company markets its fire protection services to subscribers in rural
and suburban areas, volunteer fire departments, tax-supported fire districts and
municipalities, newly developed communities, and industrial complexes, including
airports, large industrial and petrochemical plants, power plants, and other
large self-contained facilities. The Company also provides fire protection
services to newly developed communities where the subscription fee is included
in the homeowner's association assessment.
 
CONTRACTS
 
     The Company enters into contracts with counties, municipalities, and fire
districts to provide "911" emergency ambulance services in designated service
areas. These contracts typically specify maximum fees that the Company may
charge and set forth required criteria, such as response times, staffing levels,
types of vehicles and equipment, quality assurance, and insurance coverage.
Counties, municipalities, and fire districts also may require the Company to
provide a performance bond or other assurances of financial responsibility. The
amount of the subsidy, if any, that the Company receives from a county,
municipality, or fire district, and the rates that the Company may charge for
services under a contract for emergency ambulance services,
 
                                       11
<PAGE>   14
 
depend in large part on the nature of the services rendered and performance
requirements. The four largest ambulance contracts accounted for 24%, 16%, and
13% of total revenue for the fiscal years ended June 30, 1995, 1996, and 1997,
respectively, with the contract with Orange County, Florida accounting for 9%,
7%, and 5%, respectively, of total revenue for the same periods. Rates to be
charged under the Orange County contract are agreed upon between the Company and
the county. The Company does not receive any subsidy from the county under this
contract.
 
     The Company provides fire protection services pursuant to master contracts
or on a subscription basis. Master contracts provide for negotiated rates with
governmental entities. Certain contracts are performance based and require the
Company to meet certain dispatch and response times in a certain percentage of
responses. These contracts also set maximum thresholds for variances from the
performance criteria. These contracts establish the level of service required
and may encompass fire prevention and education activities as well as fire
suppression. Other contracts are level-of-effort based and require the Company
to provide a certain number of personnel for a certain time period for a
particular function, such as fire prevention or fire suppression. The largest of
these contracts accounted for 6%, 4%, and 3% of total revenue for the fiscal
years ended June 30, 1995, 1996, and 1997, respectively.
 
     The Company provides fire protection services on a subscription basis in
areas where no governmental entity has assumed the financial responsibility for
providing fire protection. The Company derived approximately 56% of its fire
protection service revenue from subscriptions for fiscal 1995, 51% for fiscal
1996, and 50% for fiscal 1997. The Company had subscription contracts with
approximately 107,000 and 109,000 subscribing households as of June 30, 1996 and
1997, respectively, and approximately 3,000 commercial subscribers as of June
30, 1996 and 1997, primarily in Arizona, Knox County, Tennessee and Grants Pass,
Oregon. Subscription fees are collected annually in advance. Subscribers also
pay a membership fee upon subscribing for service. In the event that the Company
provides service for a nonsubscriber, the Company directly bills the property
owner for the cost of services rendered. The Company has developed a
computerized fire subscription billing system that allows the Company to monitor
accounts. The Company experienced renewal rates of approximately 88% during the
prior three fiscal years. Fire subscription rates are not currently regulated by
any government agency in the Company's service areas.
 
     The Company's contracts generally extend for terms of three to five years,
with several contracts having terms of up to 10 years. The Company attempts to
renegotiate contracts substantially in advance of the expiration date and
generally has been successful in such renegotiations. The following table sets
forth certain information regarding the Company's five primary contracts at June
30, 1997 with counties, fire districts, and municipalities for ambulance
services and for fire protection services.

(6) The contract was first entered into in 1952 by the Company. The contract has
    two five-year renewal options exercisable by the City of Scottsdale.
 
     The Company also enters into contracts with hospitals, nursing homes, and
other health care facilities to provide non-emergency and critical care
ambulance services. These contracts typically designate the Company as the first
ambulance service provider contacted to provide non-emergency ambulance services
to those facilities and permit the Company to charge a base fee, mileage
reimbursement, and additional fees for the use of particular medical equipment
and supplies. The Company provides a discount in rates charged to facilities
that assume the responsibility for payment of the charges to the persons
receiving services.
 
COMPETITION
 
     The ambulance service industry is highly competitive. The principal
participants include governmental entities (including fire districts), other
national ambulance service providers, large regional ambulance service
providers, hospitals, and numerous local and volunteer private providers. In
addition, there can be no assurance that counties, municipalities, fire
districts, hospitals, or health care facilities that presently contract for
ambulance services will not choose to provide ambulance services directly in the
future. The Company is experiencing increased competition from fire departments
to provide ambulance service. Several of the Company's current and potential
competitors have greater capital and other resources than the Company. Ambulance
service providers compete primarily on the basis of quality of service,
performance, and cost. The Company believes that counties, fire districts, and
municipalities consider quality of care, historical response time performance,
and cost to be the most important factors in awarding a contract, although other
factors, such as customer service, financial stability, and personnel policies
and practices, also may be considered. Although commercial providers often
compete intensely for business within a particular community, it is generally
difficult to displace a provider that has a history of satisfying the quality of
care and response time performance criteria established within the service area.
Moreover, significant start-up costs together with the long-term nature of the
contracts under which services are provided and the relationships many providers
have within their communities create barriers to providers seeking to enter new
markets other than through acquisition.
 
     Fire protection services for residential and commercial properties are
provided primarily by tax-supported fire districts or municipalities, and
volunteer departments. Private providers represent a small portion of the total
fire protection market. The private sector provides fire protection services
primarily where a tax-supported fire district or municipality has decided to
contract for the provision of fire protection services. No assurance can be
given that fire districts or municipalities will continue to contract for fire
protection services. In areas where no governmental entity has assumed financial
responsibility for providing fire protection, the Company provides fire
protection services on a subscription basis. No assurance can be given that a
subscription area will not be annexed by a municipality or be converted to a
fire district that provides service directly rather than through a master
contract.
 
GOVERNMENTAL REGULATION
 
     The Company's business is subject to governmental regulation at the
federal, state, and local levels. At the federal level, the Company is subject
to regulations under OSHA designed to protect employees of the Company. The
federal government also recommends standards for ambulance design and
construction, medical training curriculum, and designation of appropriate trauma
facilities. Various state agencies may modify these standards.
 
     Each state in which the Company operates regulates various aspects of its
ambulance and fire business. State requirements govern the licensing or
certification of ambulance service providers, training and certification of
medical personnel, the scope of services that may be provided by medical
personnel, staffing requirements, medical control, medical procedures,
communication systems, vehicles, and equipment. The Company's contracts in its
current service areas typically prescribe maximum rates that the Company may
charge for services. The process of determining rates includes cost reviews,
analyses of levels of reimbursement from all sources, and determination of
reasonable profits. Rate setting agencies may set rates to compensate
 
                                       13
<PAGE>   16
 
service providers by requiring paying customers to subsidize those who do not or
cannot pay. Regulations applicable to ambulance services may vary widely from
state to state.
 
     Applicable federal, state, and local laws and regulations are subject to
change. The Company believes that it currently is in substantial compliance with
applicable regulatory requirements. These regulatory requirements, however, may
require the Company in the future to increase its capital and operating
expenditures in order to maintain current operations or initiate new operations.
 
REIMBURSEMENT
 
     The Company must comply with various requirements in connection with its
participation in Medicare and Medicaid. Medicare is a federal health insurance
program for the elderly and for chronically disabled individuals, which pays for
ambulance services when medically necessary. Medicare uses a charge-based
reimbursement system for ambulance services and reimburses 80% of charges
determined to be reasonable by Medicare, subject to the limits fixed for the
particular geographic area. The patient is responsible for paying the balance of
the bill, and Medicare requires the Company to expend reasonable efforts to
collect the balance. In determining reasonable charges, Medicare considers and
applies the lowest of various charge factors, including the actual charge, the
customary charge, the prevailing charge in the same locality, the amount of
reimbursement for comparable services, or the inflation-indexed charge limit.
 
     Medicaid is a combined federal-state program for medical assistance to
impoverished individuals who are aged, blind, or disabled or members of families
with dependent children. Medicaid programs or a state equivalent exist in all
states in which the Company operates. Although Medicaid programs differ in
certain respects from state to state, all are subject to federal requirements.
State Medicaid agencies have the authority to set levels of reimbursement within
federal guidelines. The Company receives only the reimbursement permitted by
Medicaid and is not permitted to collect from the patient any difference between
its customary charge and the amount reimbursed.
 
     Like other Medicare and Medicaid providers, the Company is subject to
governmental audits of its Medicare and Medicaid reimbursement claims. The
Company has not experienced significant losses as a result of any such audit.
 
     Government funding for health care programs is subject to statutory and
regulatory changes, administrative rulings, interpretations of policy,
determinations by intermediaries and governmental funding restrictions, all of
which could materially increase or decrease program reimbursements for ambulance
services. In recent years, Congress has consistently attempted to curb federal
spending on such programs. During June 1997, the Health Care Financing
Administration ("HCFA") issued proposed rules that would revise Medicare policy
on the coverage of ambulance services. Reimbursement is currently permitted if,
based on an assessment of the patient's condition, it is determined that ALS
service is medically necessary or if ALS response is required under "911"
contracts or state or local law. The new proposal would reimburse at ALS rates
only if ALS services were medically necessary. The proposed HCFA rules would
also require, among other things, that a physician's certification be obtained
prior to furnishing non-emergency ambulance service to patients, that certain
ambulance staffing requirements be maintained, that certain equipment be present
in each ambulance, and that certain additional information and documentation be
provided in order to qualify for reimbursement under the Medicare program. The
proposed rules have not been finalized. If implemented, such rules could result
in contract renegotiations or other action by the Company to offset any negative
impact of the proposed change in reimbursement policies.
 
     During August 1997, President Clinton signed the "Balanced Budget Act of
1997" (the "Budget Act"). The Budget Act provides for certain changes to the
Medicare reimbursement system, including the development and implementation of a
prospective fee schedule, by January 2000, for ambulance services. The Budget
Act mandates that this fee schedule be developed through a negotiated rulemaking
process between HFCA and ambulance service providers and must consider the
following: (i) data from industry and other organizations involved in the
delivery of ambulance services, (ii) mechanisms to control increases in
expenditures for ambulance services, (iii) appropriate regional and operational
differences, (iv) adjustments to payment rates to account for inflation and
other relevant factors, and (v) the phase-in of payment rates
 
                                       14
<PAGE>   17
 
under the fee schedule in an efficient and fair manner. Charges for ambulance
services provided during calendar years 1998 and 1999 will be increased by the
Consumer Price Index (CPI) less one percentage point.
 
     The Budget Act also stipulates that individual states may now elect to no
longer provide payment for Medicare cost-sharing for coinsurance, or copayments,
for Medicaid beneficiaries. Medicare coverage has been extended for certain
paramedic services provided in rural areas.
 
     Certain actions to partially mitigate any adverse effect of these changes
could be taken by the Company. These actions could include renegotiation of
rates and contract subsidies provided in the Company's "911" ambulance service
contracts and changes in staffing of ambulance crews based upon the negotiation
for longer response times under ambulance service contracts to reduce operating
costs.
 
     There can be no assurance whether the proposed HCFA rules, a prospective
fee schedule, or other proposals involving various aspects of Medicare
reimbursements will be adopted or the effect on the Company of any such
adoption. No assurance can be given that future funding levels for Medicare and
Medicaid programs will be comparable to present levels. Changes in the
reimbursement policies, or other government action, could adversely affect the
Company's business, results of operations, and financial condition.
 
INSURANCE
 
     The Company carries a broad range of automobile and general liability,
comprehensive property damage, malpractice, workers' compensation, and other
insurance coverages that the Company considers adequate for the protection of
its assets and operations. The Company operates in some states that adhere to
legal standards that hold emergency service providers to a gross negligence
standard in the delivery of emergency medical care, thereby subjecting them to
less exposure for tort judgments. The Company is subject to accident claims as a
result of the normal operation of its fleet of ambulances and fire vehicles.
There can be no assurance, however, that the coverage limits of the Company's
policies will be adequate. A successful claim against the Company in excess of
its insurance coverage could have a material adverse effect on the Company and
its financial condition. Claims against the Company, regardless of their merit
or outcome, also may have an adverse effect on the Company's reputation and
business. The Company has undertaken to minimize its exposure through an active
risk management program.
 
EMPLOYEES
 
     At September 26, 1997, the Company employed approximately 5,500 full-time
and 3,700 part-time employees, including approximately 6,500 involved in
ambulance services, 600 in fire protection services, 550 in integrated ambulance
and fire protection services, and 1,550 in management, administrative, clerical,
and billing activities. Of these employees, 2,700 are paramedics and 3,900 are
EMTs. The Company is a party to a collective bargaining agreement relating to
its Rochester, New York operations and to certain of its ambulance services
employees in Arizona. The Company considers its relations with employees to be
good.

SPECIAL CONSIDERATIONS
 
Dependence on Certain Business Relationships
 
     The Company depends to a great extent on certain contracts with
municipalities or fire districts to provide "911" emergency ambulance services
and fire protection services. The Company's five largest contracts accounted for
approximately 22% and 18% of total revenue for the fiscal years ended June 30,
1996 and 1997 respectively, with one contract accounting for approximately 7%
and 5% of total revenue for the same periods. The loss or cancellation of any
one or more of these contracts could have a material adverse effect on the
Company and its operations. No assurance can be given that the Company will be
successful in retaining its existing contracts or in obtaining new contracts for
ambulance services or for fire protection services. The Company also faces the
risk that areas in which it provides fire protection services through
subscription arrangements with residents and businesses will be converted to
tax-supported fire districts or annexed by municipalities. See
"Business -- Marketing and Sales," "Business -- Contracts" and
"Business -- Competition" contained in Item 1 of this Report.
 
Acquisition Strategy
 
     The Company's strategy with respect to ambulance services depends in large
part on its continued ability to acquire and to operate successfully additional
ambulance service providers. The Company completed eight acquisitions in fiscal
1994, 11 acquisitions in fiscal 1995, 16 acquisitions in fiscal 1996, and 18
acquisitions of ambulance service providers in 1997. There can be no assurance
that the Company will be able to identify additional suitable acquisition
candidates, that it will be able to consummate any such acquisitions, or that it
will be able to integrate any such acquisitions successfully into its
operations. The Company expects to use cash and securities, including Common
Stock, as the principal consideration for future acquisitions. The Company's
acquisition program could be adversely affected if the Company does not generate
sufficient cash for future acquisitions from existing operations or through
external financings. There can be no assurance that the Company's operations
will generate sufficient cash for acquisitions, that any additional financings
for acquisitions will be available if and when needed or on terms acceptable to
the Company, or that financing that is obtained will be able to be deployed on a
prompt basis. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations" contained in Item 7 of this Report.
 
Possible Adverse Changes in Reimbursement Rates of Coverage
 
     Payments received from third-party payors (including Medicare, Medicaid,
and private insurers represent a substantial portion of the Company's ambulance
receipts. The Company derived approximately 79% and 74% of its net ambulance fee
collections from such third-party payors during 1996 and 1997; including 27% and
26% from Medicare, respectively. There are continuing efforts of third-party
payors to control expenditures for health care, including proposals to revise
reimbursement policies.
 
     During June 1997 HCFA issued proposed rules that would revise Medicare
policy on the coverage of ambulance services. These proposed rules have been
subject to public comment and, despite the passage of new law addressing changes
to the reimbursement of ambulance services by Medicare (discussed below),
 
                                       18
<PAGE>   21
 
have not yet been withdrawn. The proposed new HCFA rules have not been
finalized. See "Business -- Reimbursement" contained in Item 1 of this Report.
 
     In addition, in August 1997, the Budget Act became law. The Budget Act
provides for the development, negotiation, and implementation of a prospective
fee schedule for ambulance services between HCFA and ambulance service providers
by January 2000. The Budget Act also reduces the annual rate adjustment for
Medicare reimbursements from the Consumer Price Index (CPI) to CPI less one
percentage point.
 
     If the proposed HCFA rules were to be finalized prior to the negotiation of
a prospective fee schedule as stipulated in the Budget Act, and the Company were
unable to mitigate the effect of the new rules, the Company's results of
operations could be adversely effected. The final outcome of the proposed rules
and the effect of the prospective fee schedule is uncertain. However, changes in
reimbursement policies, or other government action, together with the financial
instability of private third-party payors and budget pressures on payor sources
could influence the timing and, potentially, the ultimate receipt of
reimbursements. A reduction in coverage or reimbursement rates by third-party
payors could have a material adverse effect on the Company's results of
operations. See "Business -- Billings and Collections," "Business -- Government
Regulation," and "Business -- Reimbursement" contained in Item 1 of this Report.
 
Impact of Rate Structures and Limitations on Rates of Return
 
     State or local government regulations or administrative policies regulate
rate structures in most states in which the Company conducts ambulance
operations. In certain service areas in which the Company is the exclusive
provider of services, the municipality or fire district sets the rates for
emergency service pursuant to a master contract and establishes the rates for
general ambulance services that the Company is permitted to charge. Rates in
most service areas are set at the same amounts for emergency and general
ambulance services. The State of Arizona establishes a rate of return on sales
the Company is permitted to earn in determining the ambulance service rates the
Company may charge in that state. Ambulance services revenue generated in
Arizona accounted for approximately 11% and 9% of total revenue for the fiscal
years ended June 30, 1996 and 1997, respectively. No assurance can be given that
the Company will be able to receive ambulance service rate increases on a timely
basis where rates are regulated or to establish or maintain satisfactory rate
structures where rates are not regulated. Under present coverage programs with
third-party payors, the Company faces the continuing risk of nonreimbursement to
the extent that uninsured individuals require ambulance service. Changes in
demographics in the Company's markets could increase the Company's risk of
doubtful accounts which, in turn, could have a material adverse effect on the
Company's operating results. See "Business -- Billings and Collections" and
"Business -- Governmental Regulation" contained in item 1 of this Report.
 
     Municipalities and fire districts negotiate the payments to be made to the
Company for fire protection services pursuant to master contracts. These master
contracts are based on a budget and on level of effort or performance criteria
desired by the municipalities and fire districts. No assurance can be given that
the Company will be successful in negotiating or maintaining profitable
contracts with municipalities and fire districts. See "Business -- Contracts"
contained in Item 1 of this Report.
 
Governmental Regulation
 
     Numerous federal, state, and local laws and regulations govern various
aspects of the business of ambulance service providers, covering matters such as
licensing, rates, employee certification, environmental matters, and other
factors. Certificates of necessity may be required from state or local
governments to operate ambulance services in a designated service area. Master
contracts from governmental authorities are subject to risks of cancellation or
unenforceability as a result of budgetary and other factors and may subject the
Company to certain liabilities or restrictions which traditionally have applied
only to governmental bodies or to which they are otherwise immune. There can be
no assurance that federal, state, or local governments will not adopt laws or
regulations that would increase the Company's cost of doing business, lower
reimbursement levels, or otherwise have a material adverse effect on the

Industry Considerations
 
     Numerous legislative proposals have been considered that would result in
major reforms in the United States health care system. The Company cannot
predict which, if any, health care reforms may be proposed or enacted or the
effect that any such legislation would have on the Company's business. In
addition, managed care providers are attempting to contain health care costs
through the use of outpatient services and specialized treatment facilities. No
assurance can be given that changing industry practices will not have an adverse
effect on the Company.
 
Competition
 
     The ambulance service industry is highly competitive. The Company currently
encounters competition in providing ambulance services from governmental
entities (including fire districts), hospitals, other national ambulance service
providers, large regional ambulance service providers, and numerous local and
volunteer private providers. In addition, there can be no assurance that
municipalities, fire districts, or health care organizations that currently
contract for ambulance services will not choose to provide ambulance services
directly in the future. The Company is experiencing increased competition from
fire departments to provide emergency ambulance service. Some of the Company's
current competitors and certain potential competitors have greater capital and
other resources than the Company. Tax-supported fire districts, municipal fire
departments, and volunteer fire departments represent the principal providers of
fire protection services for residential and commercial properties. Private
providers represent only a small portion of the total fire protection market and
generally provide services where a tax-supported municipality or fire district
has decided to contract for the provision of fire protection services or has not
assumed the financial responsibility for fire protection. In these situations,
the Company provides services for a municipality or fire district on a contract
basis or provides fire protection services directly to residences and businesses
on a subscription basis. There can be no assurance that the Company will be able
to obtain additional fire protection businesses on a contractual or subscription
basis, that fire districts or municipalities will not choose to provide fire
protection services directly in the future, or that areas in which the Company
provides services through subscriptions will not be converted to tax-supported
fire districts or annexed by municipalities. See "Business -- Competition"
contained in Item 1 of this Report.
 
Dependence on Management and Other Key Personnel
 
     The Company's success depends upon the retention of principal key personnel
and the recruitment and retention of additional key personnel. The loss of
existing key personnel or the failure to recruit and retain necessary additional
personnel would adversely affect the Company's business prospects. There can be
no assurance that the Company will be able to retain its current personnel or
attract and retain necessary additional personnel. The Company's internal growth
and its expansion into new geographic areas will require additional expertise,
such as marketing and operational management. These growth and expansion
activities will further increase the demand on the Company's resources and
require the addition of new personnel and the development of additional
expertise by existing personnel. The failure of the Company to attract and
retain personnel with the requisite expertise or to develop internally such
expertise could adversely affect the prospects for the Company's success. The
Company entered into three-year employment agreements with its executive
officers in May 1993, which were renewed in December 1995, and has entered into
similar agreements with certain other executive officers as they have joined the
Company. The Company maintains "key person" insurance on several of its key
executive officers. See "Business -- Executive Officers and Key Employees"
contained in Item 1 of this Report.
 
Control by Current Stockholders
 
     The directors, executive officers, and their affiliates currently own
beneficially approximately 10%, and the Company's Employee Stock Ownership Plan
(the "ESOP") currently holds approximately 8%, of the outstanding shares of
Common Stock. Accordingly, these persons, if they act as a group, likely will be
able to significantly influence the election of the Company's directors and the
outcome of matters requiring approval by the stockholders of the Company.
 
                                       20

Change in Control Provisions
 
     The Company's Second Restated Certificate of Incorporation (the "Restated
Certificate") and the Delaware General Corporation Law (the "General Corporation
Law") contain provisions that may have the effect of making more difficult or
delaying attempts by others to obtain control of the Company, even when these
attempts may be in the best interests of stockholders. The Restated Certificate
also authorizes the Board of Directors, without stockholder approval, to issue
one or more series of preferred stock which could have voting and conversion
rights that adversely affect the voting power of the holders of Common Stock and
provides for a classified board of directors. The General Corporation Law also
imposes conditions on certain business combination transactions with "interested
stockholders" (as defined therein).
 
     The Company has also adopted a Rights Plan whereby, if and when the Rights
become exercisable, holders of shares of Common Stock will be entitled to
purchase one one-thousandth of a share of Series A Junior Participating
Preferred Stock at a purchase price of $145 (subject to certain antidilution
adjustments). The Rights will expire 10 years after issuance, and will be
exercisable only if a person or group becomes the beneficial owner of 15% or
more of the Common Stock (such person or group, a "15% holder") or commences a
tender or exchange offer which would result in the offeror beneficially owning
15% or more of the Common Stock. If the Rights become exercisable, each Right,
unless redeemed by the Company, entitles the holder to purchase for $145 an
amount of Common Stock of the Company, or in certain circumstances a combination
of securities and/or assets or the common stock of the acquiror, having a market
value of twice the purchase price.
 
     The Rights have certain anti-takeover effects. The Rights will cause
substantial dilution to a person or group that attempts to acquire the Company
on terms not approved by the Company's Board of Directors, except pursuant to an
offer conditioned on a substantial number of Rights being acquired. The Rights
should not interfere with any merger or other business combination approved by
the Board of Directors since the Rights may be redeemed by the Company at $.01
per Right prior to 10 days (as such period may be extended) after the public
announcement of the existence of a 15% holder.
 
Possible Volatility of Stock
 
     The market price of the Company's Common Stock has increased since the
Company's initial public offering in July 1993. See "Market for the Registrant's
Common Equity and Related Stockholder Matters" contained in Item 5 of this
Report. The period was marked by generally rising stock prices, favorable
industry conditions, and improved operating results by the Company. The trading
price of the Company's Common Stock in the future could be subject to wide
fluctuations in response to quarterly variations in operating results of the
Company and others in its industry, actual or anticipated announcements
concerning the Company or its competitors, including government regulations and
reimbursement changes, the announcement and implementation of health care reform
proposals, changes in analysts' estimates of the Company's financial
performance, general conditions in the health care industry, general economic
and financial conditions, and other events or factors. In addition, the stock
market has experienced extreme price and volume fluctuations which have affected
the market prices for many companies involved in health care and related
industries and which often have been unrelated to the operating performance of
such companies. These broad market fluctuations and other factors may adversely
affect the market price of the Company's Common Stock. See
"Business -- Competition" and "Business -- Governmental Regulation" contained in
Item 1 of this Report.
 
Shares Eligible for Future Sale
 
     Sales of substantial amounts of Common Stock in the public market could
adversely affect prevailing market prices. As of September 26, 1997, there were
13,157,348 shares of Common Stock outstanding, 9,874,095 shares of which were
freely transferable without restriction under the Securities Act of 1933, as
amended (the "Securities Act"), unless held by an "affiliate" of the Company, as
that term is defined under the Securities Act. The Company also has outstanding
136,313 restricted shares, as that term is defined under Rule 144 (the
"Restricted Shares") under the Securities Act, that are eligible for sale in the
public market subject to compliance with the holding period, volume limitations,
and other requirements of Rule 144. In
 
                                       21
<PAGE>   24
 
addition, the Company has registered 3,200,000 shares of Common Stock for
issuance in connection with acquisitions (of which 3,146,940 shares have been
issued), which shares are generally freely tradeable after their issuance under
Rule 145 of the Securities Act, unless held by an affiliate of the acquired
company, in which case such shares will be subject to the volume and manner of
sale restrictions under Rule 144.
 
     The Company has registered for offer and sale up to 3,965,625 shares of
Common Stock that are reserved for issuance pursuant to the Company's stock
option plans. Shares issued after the effective date of such registration
statement upon the exercise of stock options issued under the Company's stock
option plans generally will be eligible for sale in the public market, except
that affiliates of the Company will continue to be subject to volume
limitations. The Company also has the authority to issue additional shares of
Common Stock and shares of one or more series of Preferred Stock. The issuance
of such shares could have a dilutive effect on earnings per share, and the sale
of such shares could depress the market price of the Company's Common Stock.
 
ITEM 2.  PROPERTIES
 
FACILITIES AND EQUIPMENT
 
     The Company leases its principal executive offices in Scottsdale, Arizona.
The Company leases administrative facilities and other facilities used
principally for ambulance and fire apparatus basing, garaging and maintenance in
those areas in which it provides ambulance and fire protection services. The
Company also owns six administrative facilities and 11 other facilities within
its service areas. Aggregate rental expense was approximately $5.3 million and
$6.6 million during fiscal 1996 and 1997, respectively. At September 26, 1997,
the Company's fleet included 1,363 owned and 198 leased ambulances, 120 owned
and 15 leased fire vehicles and 250 owned and 15 leased other vehicles.
 
ITEM 3.  LEGAL PROCEEDINGS
 
     The Company from time to time is subject to litigation arising in the
ordinary course of business. There can be no assurance that the Company's
insurance coverage will be adequate to cover all liabilities occurring out of
such claims. In the opinion of management, the Company is not engaged in any
legal proceedings expected to have a material adverse effect on the financial
condition or results of operations of the Company.
 
ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
     None.

     On September 26, 1997, the closing sale price of the Company's Common Stock
was $30.50 per share. On September 26, 1997, there were approximately 1,005
holders of record of the Company's Common Stock.
 
     Pursuant to a private placement under Section 4(2) of the Securities Act,
in May 1997, the Company issued 11,751 shares at $30.63 per share to the former
shareholder of Response Medical Transport Service, Inc. ("Response") in
connection with the Company's acquisition of Response. In June 1997, pursuant to
Section 4(2), the Company issued 3,414 shares at $29.63 per share to the two
former shareholders of Lindsay and District Ambulance Service Ltd., 3,414 shares
at $29.63 per share to the two former shareholders of Owen Sound Emergency
Services Inc., 3,414 shares at $29.63 per share to the former shareholder of
Port Colborne and District Ambulance Service Ltd., and 3,414 shares at $29.63
per share to the two former shareholders of Noel Ambulance Service Limited in
connection with the Company's acquisition of such companies.
 
DIVIDEND POLICY
 
     The Company has never paid any cash dividends on its Common Stock. The
Company currently plans to retain earnings to finance the growth of the
Company's business rather than to pay cash dividends. Payments of any cash
dividends in the future will depend on the financial condition, results of
operations, and capital requirements of the Company as well as other factors
deemed relevant by the Board of Directors. The Company's term notes and
revolving credit facility contain restrictions on the Company's ability to pay
cash dividends, and future borrowings may contain similar restrictions. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources" contained in Item 7 of this
Report.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS
 
     The following discussion and analysis should be read in conjunction with
the Selected Consolidated Financial Data and the Consolidated Financial
Statements of the Company and related notes appearing elsewhere in this report
on Form 10-K.
 
INTRODUCTION
 
     The Company derives its revenue primarily from fees charged for ambulance
and fire protection services. The Company provides ambulance services in
response to emergency medical calls ("911" emergency ambulance services) and
non-emergency transport services (general transport services) to patients on
both a fee-for-service basis and nonrefundable subscription fee basis. Per
transport revenue depends on various factors, including the mix of rates between
existing markets and new markets and the mix of activity between "911" emergency
ambulance services and general transport services as well as other competitive
factors. Fire protection services are provided either under contracts with
municipalities or fire districts or on a nonrefundable subscription fee basis to
individual homeowners or commercial property owners.
 
     Ambulance service fees are recorded net of Medicare, Medicaid, and other
reimbursement limitations and are recognized when services are provided.
Payments received from third-party payors represent a substantial portion of the
Company's ambulance service fee receipts. Provision for doubtful accounts is
made for the expected difference between ambulance services fees charged and
amounts actually collected. The Company's provision for doubtful accounts
generally is higher with respect to collections to be derived directly from
patients than for collections to be derived from third-party payors and
generally is higher for "911" emergency ambulance services than for general
ambulance transport services.
 
     Because of the nature of the Company's ambulance services, it is necessary
to respond to a number of calls, primarily "911" emergency ambulance service
calls, which may not result in transports. Results of operations are discussed
below on the basis of actual transports since transports are more directly
related to revenue. Expenses associated with calls that do not result in
transports are included in operating expenses. The percentage of calls not
resulting in transports varies substantially depending upon the mix of general
transport and "911" emergency ambulance service calls in the Company's markets
and is generally higher in markets in which the calls are primarily "911"
emergency ambulance service calls. Rates in the Company's markets take into
account the anticipated number of calls that may not result in transports. The
Company does not separately account for expenses associated with calls that do
not result in transports.
 
     Revenue generated under fire protection services contracts is recognized
over the life of the contract. Subscription fees received in advance are
deferred and recognized over the term of the subscription agreement, which
generally is one year.
 
                                       25
<PAGE>   28
 
     Other revenue primarily consists of fees associated with alternative
transportation services and home health care services and are recognized when
the services are provided.
 
     Other operating expenses primarily consist of rent and related occupancy
expenses, maintenance and repairs, insurance, fuel and supplies, travel and
professional fees.
 
     The Company's net income for the year ended June 30, 1997 was $12.7 million
or $1.04 per share. This compares to net income of $11.5 million and $6.9
million, or $1.14 and $0.84 per share for the years ended June 30, 1996 and
1995, respectively. Included in 1995 net income is an extraordinary charge to
earnings of $0.7 million, net of a $0.5 million tax benefit, or $0.08 per share,
to reflect the loss on early extinguishment of debt. During fiscal 1997, the
Company completed the acquisition of eighteen ambulance service providers
operating in Arizona, Arkansas, Georgia, Indiana, Kentucky, New York, Ohio,
Pennsylvania and Ontario, Canada. The following discussion provides greater
detail of the Company's results of operations and liquidity and capital
resources.

YEAR ENDED JUNE 30, 1996 COMPARED TO YEAR ENDED JUNE 30, 1997
 
Revenue
 
     Total revenue increased $69.5 million, or 27.8%, from $250.3 million for
the year ended June 30, 1996 to $319.8 million for the year ended June 30, 1997.
Approximately $43.6 million of this increase resulted from the acquisition of
ambulance service providers during fiscal 1997. Fire protection services revenue
increased by $3.4 million, and other revenue increased by $5.9 million.
 
     Total ambulance transports increased by 205,000, or 28.9%, from 710,000 for
the year ended June 30, 1996 to 915,000 for the year ended June 30, 1997. The
acquisition of eighteen ambulance service companies during fiscal 1997 accounted
for 154,000 of these additional transports.
 
                                       26
<PAGE>   29
 
     Fire protection services revenue increased due to rate increases for fire
protection services and greater utilization of the Company's services under
fee-for-service arrangements. The increase also resulted from the revenue
generated from new fire protection contracts awarded to the Company through
competitive bidding.
 
Operating Expenses
 
     Payroll and employee benefit expenses increased $35.4 million, or 26.1%,
from $135.4 million for the year ended June 30, 1996 to $170.8 million for the
year ended June 30, 1997. This increase was primarily due to the acquisition of
nineteen companies during fiscal 1997. Payroll and employee benefits decreased
from 54.1% of total revenue for the year ended June 30, 1996 to 53.4% of total
revenue for the year ended June 30, 1997 as a result of operational
efficiencies.
 
     Provision for doubtful accounts increased $12.4 million, or 40.0%, from
$31.0 million for the year ended June 30, 1996 to $43.4 million for the year
ended June 30, 1997. Provision for doubtful accounts increased from 12.4% of
total revenue for the year ended June 30, 1996 to 13.6% of total revenue for the
year ended June 30, 1997, reflecting the effect of the acquisition of ambulance
service providers operating in markets with a greater mix of "911" emergency
activity.
 
     Depreciation increased $2.3 million, or 23.5%, from $9.8 million for the
year ended June 30, 1996 to $12.1 million for the year ended June 30, 1997,
primarily due to increased property and equipment from recent acquisition
activity.
 
     Amortization of intangibles increased by $1.1 million, or 30.6%, from $3.6
million for the year ended June 30, 1996 to $4.7 million for the year ended June
30, 1997. This increase was the result of increased intangible assets caused by
recent acquisition activity. Amortization of intangibles increased from 1.4% of
total revenue for the year ended June 30, 1996 to 1.5% for the year ended June
30, 1997.
 
     Other operating expenses increased $9.2 million, or 20.1%, from $45.7
million for the year ended June 30, 1996 to $54.9 million for the year ended
June 30, 1997, primarily as a result of increased expenses associated with the
operation of the nineteen companies acquired during fiscal 1997. Other operating
expenses decreased from 18.3% of total revenue for the year ended June 30, 1996
to 17.1% of total revenue for the year ended June 30, 1997 as a result of
operational efficiencies.
 
     The Company recorded a $6.0 million non-recurring pre-tax charge for the
year ended June 30, 1997. Included in this amount was an allowance of $3.2
million related to an unprofitable ambulance service contract. Also included was
a restructuring charge of $2.8 million relating to the integration of ambulance
company acquisitions. The charge consists primarily of severance costs and other
costs related to the elimination of redundant functions. Management expects the
integration to be completed during fiscal 1998.
 
     Interest expense increased by $0.6 million, or 11.8%, from $5.1 million for
the year ended June 30, 1996 to $5.7 million for the year ended June 30, 1997.
This increase was caused by higher debt balances, reflecting increased
borrowings on the Company's revolving credit facility.
 
     The Company's effective tax rate increased from 41.1% for the year ended
June 30, 1996 to 42.4% for the year ended June 30, 1997, primarily the result of
a higher percentage of the Company's taxable income being generated in higher
tax rate states and the effect of nondeductible goodwill generated in connection
with the acquisition of certain ambulance service providers.
 
YEAR ENDED JUNE 30, 1995 COMPARED TO YEAR ENDED JUNE 30, 1996
 
Revenue
 
     Total revenue increased $78.7 million, or 45.9%, from $171.6 million for
the year ended June 30, 1995 to $250.3 million for the year ended June 30, 1996.
Approximately $56.1 million of this increase resulted from the acquisition of
ambulance service providers during fiscal 1996. Fire protection services revenue
increased by $6.5 million, and other revenue increased by $2.4 million.
 
                                       27
<PAGE>   30
 
     Total ambulance transports increased by 241,000, or 51.4%, from 469,000 for
the year ended June 30, 1995 to 710,000 for the year ended June 30, 1996. The
acquisition of sixteen ambulance service companies during fiscal 1996 accounted
for 227,000 of these additional transports.
 
     Fire protection services revenue increased due to rate increases for fire
protection services and greater utilization of the Company's services under
fee-for-service arrangements. The increase also resulted from the acquisition of
a fire protection service company during the first quarter of fiscal 1996 and
revenue generated from new fire protection contracts awarded to the Company
through competitive bidding.
 
Operating Expenses
 
     Payroll and employee benefit expenses increased $44.6 million, or 49.1%,
from $90.8 million for the year ended June 30, 1995 to $135.4 million for the
year ended June 30, 1996. This increase was primarily due to the acquisition of
eighteen companies during fiscal 1996.
 
     Provision for doubtful accounts increased $8.7 million, or 39.0%, from
$22.3 million for the year ended June 30, 1995 to $31.0 million for the year
ended June 30, 1996. Provision for doubtful accounts decreased from 13.0% of
total revenue for the year ended June 30, 1995 to 12.4% of total revenue for the
year ended June 30, 1996, reflecting the effect of the acquisition of ambulance
service providers operating in markets with higher receivable collections as a
result of a greater mix of general transport activity.
 
     Depreciation increased $3.1 million, or 46.3%, from $6.7 million for the
year ended June 30, 1995 to $9.8 million for the year ended June 30, 1996,
primarily due to increased property and equipment from recent acquisition
activity.
 
     Amortization of intangibles increased by $1.5 million, or 71.4%, from $2.1
million for the year ended June 30, 1995 to $3.6 million for the year ended June
30, 1996. This increase was the result of increased intangible assets caused by
recent acquisition activity. Amortization of intangibles increased from 1.2% of
total revenue for the year ended June 30, 1995 to 1.4% for the year ended June
30, 1996.
 
     Other operating expenses increased $11.9 million, or 35.2%, from $33.8
million for the year ended June 30, 1995 to $45.7 million for the year ended
June 30, 1996, primarily as a result of increased expenses associated with the
operation of the eighteen companies acquired during fiscal 1996. Other operating
expenses decreased from 19.7% of total revenue for the year ended June 30, 1995
to 18.3% of total revenue for the year ended June 30, 1996 as a result of
operational efficiencies.
 
     Interest expense increased by $2.0 million, or 64.5%, from $3.1 million for
the year ended June 30, 1995 to $5.1 million for the year ended June 30, 1996.
This increase was caused by higher debt balances, reflecting increased
borrowings on the Company's revolving credit facility.
 
     The Company's effective tax rate increased from 41.0% for the year ended
June 30, 1995 to 41.1% for the year ended June 30, 1996, primarily the result of
a higher percentage of the Company's taxable income being generated in higher
tax rate states and the effect of nondeductible goodwill generated in connection
with the acquisition of certain ambulance service providers. This increase was
partially offset by tax planning strategies implemented by the Company during
fiscal 1996.

     The Company has historically experienced, and expects to continue to
experience, moderate seasonality in quarterly operating results. This
seasonality has resulted from a number of factors, including relatively higher
second and third fiscal quarter demand for transport services in the Company's
Arizona and Florida regions resulting from the greater winter populations in
those regions. The effect of the acquisition of ambulance service providers in
the northeastern and midwestern regions of the United States has reduced, and
will continue to reduce, the overall seasonality in operating results.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Historically, the Company has financed its cash requirements principally
through cash flow from operating activities, term and revolving indebtedness,
capital equipment lease financing, and the sale of stock through an initial
public offering in July 1993, generating net proceeds of approximately $19.5
million, and subsequent public stock offering in May 1994 and April 1996,
generating net proceeds of approximately $17.4 million and $34.8 million,
respectively.
 
     During the year ended June 30, 1997, the Company used $11.1 million in cash
flow from operations compared with $1.4 million provided by operations in the
preceding year, due primarily to increases in accounts receivable, inventories
and prepaid expenses and decreases in accounts payable and accrued liabilities.
 
     During September 1995, the Company funded a fully underwritten credit
agreement for a $125.0 million revolving credit facility. The Company used the
proceeds from the facility to repay the Company's then existing revolving credit
facility and its notes payable. Costs previously deferred related to certain
indebtedness resulted in an extraordinary charge to earnings of $693,000, net of
a $480,000 tax benefit, or $.08 per share in the year ended June 30, 1995. In
May 1997, the credit agreement was increased from $125.0 million to $175.0
million. Approximately $134.0 million was outstanding on the credit facility at
June 30, 1997. This six-year revolving credit facility is priced at the prime
rate or a LIBOR-based rate. The LIBOR-based rates range from LIBOR plus 0.75% to
LIBOR plus 1.75% depending upon the Company meeting certain financial covenants.
Beginning September 30, 1999, the amount available under the facility begins to
reduce at three-month intervals until the termination date at September 30,
2001. The facility is collateralized by the Company's accounts and notes
receivable, common stock of its subsidiaries and partnership interests. At
September 26, 1997, borrowings on the revolving credit facility were
approximately $150.0 million. At June 30, 1997, the Company had availability of
approximately $37.0 million under the revolving credit facility.
 
     Exclusive of payments on the revolving credit facility, the Company repaid
$21.3 million of notes payable and capital lease obligations during the year
ended June 30, 1997 and $20.3 million during the year ended June 30, 1996.
Capital expenditures were $23.9 million during the year ended June 30, 1997
compared to

$18.2 million during the prior year, of which $2.0 million was financed through
capital lease obligations in the year ended June 30, 1996.
 
     During the year ended June 30, 1997, the Company purchased either all of
the issued and outstanding stock or certain of the assets of nineteen companies
operating in Arizona, Arkansas, Georgia, Indiana, Kentucky, New York, Ohio,
Pennsylvania and Ontario, Canada. The combined purchase price was $82.6 million.
The Company paid cash of $35.5 million, issued notes payable to sellers totaling
$4.5 million, issued 1.2 million shares of common stock to sellers (361,970
shares were related to pooling-of-interests transactions and the remaining
shares were valued at $18.7 million), and assumed $23.9 million of liabilities.
The Company funded the cash portion of the acquisitions through operating cash
flow and from the Company's revolving credit facility.
 
     Subsequent to June 30, 1997 the Company purchased either all the issued and
outstanding stock or certain assets of four ambulance service providers with
operations in Alabama, Georgia, Mississippi, New Jersey, New York and Tennessee.
The combined purchase price was $6.1 million. The Company paid cash of $3.7
million, issued notes payable to sellers of $1.2 million and assumed $1.2
million of liabilities. The Company issued 641,009 shares related to two of the
acquisitions which were recorded as pooling-of-interests transactions.
 
     The Company expects that existing working capital, together with cash flow
from operations and additional borrowing capacity, will be sufficient to meet
its operating and capital needs for existing operations for the twelve months
subsequent to June 30, 1997. The Company is engaged in an active acquisition
program. The Company intends to fund any acquisitions that it consummates
through the use of cash from operations, credit facilities, seller notes payable
and the issuance of common stock. In addition, the Company may seek to raise
additional capital through public or private debt or equity financings. The
availability of these capital sources will depend upon prevailing market
conditions, interest rates and the financial condition of the Company.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Rural/Metro Corporation:
 
     We have audited the accompanying consolidated balance sheets of RURAL/METRO
CORPORATION (a Delaware corporation) and subsidiaries as of June 30, 1997 and
1996, and the related consolidated statements of income, changes in
stockholders' equity and cash flows for each of the three years in the period
ended June 30, 1997. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
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 financial statements referred to above present fairly,
in all material respects, the financial position of Rural/Metro Corporation and
subsidiaries as of June 30, 1997 and 1996, and the results of their operations
and their cash flows for each of the three years in the period ended June 30,
1997, in conformity with generally accepted accounting principles.
 
     Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The schedule listed in the index to
financial statements and supplementary data is presented for purposes of
complying with the Securities and Exchange Commission's rules and is not a
required part of the basic financial statements. This information has been
subjected to the auditing procedures applied in our audits of the basic
financial statements and, in our opinion, fairly state in all material respects
the financial data required to be set forth therein in relation to the basic
financial statements taken as a whole.

                            RURAL/METRO CORPORATION
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(1) THE COMPANY AND ITS SIGNIFICANT ACCOUNTING POLICIES
 
NATURE OF BUSINESS AND OPERATIONS
 
     Rural/Metro Corporation, a Delaware corporation, and its subsidiaries
(collectively, the Company) is a diversified emergency services company
providing ambulance transport services, fire protection and training services,
and home health care services and equipment in 21 states, Canada and Latin
America. The Company provides "911" emergency and general transport ambulance
services to patients on both a fee-for-service basis and a non-refundable
subscription fee basis. Fire protection services are provided either under
contracts with municipalities or fire districts, or on a non-refundable
subscription fee basis to individual homeowners or commercial property owners.
 
     The Company depends on certain contracts with municipalities or fire
districts to provide "911" emergency ambulance services and fire protection
services. The five largest contracts accounted for 18%, 22%, and 30% of total
revenue for the fiscal years ended June 30, 1997, 1996 and 1995, respectively,
with the largest of the five contracts accounting for 5%, 7%, and 9%,
respectively, of total revenue for the same periods. These contracts are subject
to requests for proposals, competitive bid processes or renegotiation upon
expiration and may be subject to termination for failure to meet performance
criteria.
 
PRINCIPLES OF CONSOLIDATION
 
     The financial statements include the accounts of Rural/Metro Corporation
and its subsidiaries. All significant intercompany accounts and transactions
have been eliminated in consolidation.
 
REVENUE RECOGNITION
 
     Ambulance service fees are recorded net of Medicare, Medicaid and other
reimbursement limitations and recognized when services are provided. During the
years ended June 30 1997, 1996 and 1995, the Company derived approximately 26%,
27% and 33%, respectively, of its net ambulance fee collections from Medicare
and 10%, 11% and 12%, respectively, from Medicaid. Provision for doubtful
accounts is recorded for the expected difference between net ambulance service
fees and amounts actually collected. The continuing efforts of third party
payors to control expenditures for health care could affect the revenue, cash
flows and profitability of the Company.
 
     During August 1997, President Clinton signed the "Balanced Budget Act of
1997" (the Act). The Act provides for certain changes to the Medicare
reimbursement system. These changes include, among other things, the creation of
a Medicare Payment Advisory Commission to review payment policies and health
care delivery, and make recommendations to Congress concerning such payment
policies.
 
     In addition, the Act provides for the development and implementation of a
prospective fee schedule, by January 2000, for ambulance services. The Act
mandates that this fee schedule be developed through a negotiated rulemaking
process and must consider the following: (i) data from industry and other
organizations involved in the delivery of ambulance services, (ii) mechanisms to
control increases in expenditures for ambulance services, (iii) appropriate
regional and operational differences, (iv) adjustments to payment rates to
account for inflation and other relevant factors, and (v) the phase-in of
payment rates under the fee schedule in an efficient and fair manner. Medicare
reimbursement for ambulance services provided during calendar years 1998 and
1999 will be increased by the Consumer Price Index (CPI) less one percentage
point.
 
     The Act also stipulates that individual states may now elect to no longer
provide payment for Medicare cost-sharing for coinsurance, or copayments, for
Medicaid beneficiaries. The Act also extended Medicare coverage for certain
paramedic services provided in rural areas.
 
                                       F-7

                            RURAL/METRO CORPORATION
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Due to the uncertainty associated with the negotiation and subsequent
outcome of the prospective fee schedule, the Company is unable to predict the
ultimate impact of the Act. However, future impact of the Act, together with the
financial instability of private third-party payors, budget pressures on payor
sources and cost shifting by government, could influence the timing and,
potentially, the ultimate receipt of reimbursements.
 
     Revenue generated under fire protection service contracts is recognized
over the life of the contract. Subscription fees received in advance are
deferred and recognized over the term of the subscription agreement, generally
one year.
 
     Other revenue is comprised primarily of fees associated with alternative
transportation services and home health care services and is recognized when the
services are provided.
 
EARNINGS PER SHARE
 
     Earnings per share is computed by dividing net income available for common
stock by the weighted average number of shares of common stock and common stock
equivalents assumed outstanding during the period. Primary and fully diluted
earnings per share are considered to be the same in all periods presented.
 
     In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards (SFAS) No. 128, "Earnings Per Share", which
supersedes Accounting Principles Board (APB) Opinion No. 15, the existing
authoritative guidance. SFAS No. 128 is effective for financial statements for
both interim and annual periods ending after December 15, 1997 and requires
restatement of all prior period earnings per share (EPS) data presented. The new
statement modifies the calculation of primary and fully diluted EPS and replaces
them with basic and diluted EPS. Pro forma EPS, assuming implementation of SFAS
No. 128 at the beginning of the years ended June 30, 1997, 1996 and 1995, is as
follows:

INVENTORIES
 
     Inventories, consisting of ambulance, fire and home health care supplies,
are stated at the lower of cost, on a first-in, first-out basis, or market.
 
PROPERTY AND EQUIPMENT
 
     Property and equipment is stated at cost, net of accumulated depreciation,
and is depreciated over the estimated useful lives using the straight-line
method. Equipment and vehicles are depreciated over three to ten years and
buildings are depreciated over fifteen to thirty years. Property and equipment
held under capital leases is stated at the present value of minimum lease
payments, net of accumulated amortization. These assets are amortized over the
lesser of the lease term or the estimated useful life of the underlying assets
using the straight-line method. Major additions and improvements are
capitalized; maintenance and repairs which do not improve or significantly
extend the life of assets are expensed as incurred.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
INTANGIBLE ASSETS
 
     Intangible assets include costs in excess of the fair value of net assets
of businesses acquired of $159,949,000 and $95,827,000 and covenants not to
compete of $333,000 and $546,000 at June 30, 1997 and 1996, respectively. Costs
in excess of the fair value of net assets acquired are amortized over
twenty-five to thirty-five years using the straight-line method. Covenants not
to compete are amortized using the straight-line method over the term of the
related agreements, generally three to five years. Accumulated amortization of
these intangible assets was $10,318,000 and $6,092,000 at June 30, 1997 and
1996, respectively.
 
ACCRUED LIABILITIES
 
     Included in accrued liabilities is $7,556,000 and $6,450,000 for salaries,
wages and related payroll expenses and $1,679,000 and $1,618,000 for accrued
insurance premiums at June 30, 1997 and 1996, respectively.
 
LOSS CONTRACT/RESTRUCTURING CHARGE
 
     During the year ended June 30, 1997 the Company recorded a pre-tax charge
of $6.0 million. Included in this amount was an allowance of $3.2 million
related to an unprofitable ambulance service contract of which $2.0 million of
the allowance remains at June 30, 1997. Also included was a pre-tax
restructuring charge of $2.8 million relating to the integration of ambulance
company acquisitions. The charge consists primarily of severance costs and other
costs related to the elimination of redundant functions. Management expects the
integration to be completed during fiscal 1998. The entire $2.8 million
allowance remains at June 30, 1997. Both allowances are included in accrued
liabilities on the accompanying consolidated balance sheets.
 
CONCENTRATIONS OF CREDIT RISK
 
     Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of cash equivalents and
accounts receivable. The Company places its cash equivalents with
federally-insured institutions and limits the amount of credit exposure to any
one institution. Concentrations of credit risk with respect to accounts
receivable are limited due to the large number of customers comprising the
Company's credit base and the geographical dispersion of the customers.
 
USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities,
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The estimated fair value of financial instruments has been determined by
the Company using available market information and valuation methodologies.
Considerable judgment is required in interpreting market data to develop the
estimates of fair value. Accordingly, the estimates may not be indicative of the

REVOLVING CREDIT FACILITY
 
     During September 1995, the Company funded a fully underwritten credit
agreement for a $125.0 million revolving credit facility. The Company used the
proceeds from the facility to repay the Company's then existing revolving credit
facility and its notes payable. Costs previously deferred related to certain
indebtedness resulted in an extraordinary charge to earnings of $693,000, net of
a $480,000 tax benefit, or $.08 per share in the year ended June 30, 1995. In
May 1997, the credit agreement was increased form $125.0 million to $175.0
million. This six-year revolving credit facility is priced at the prime rate or
a LIBOR-based rate. The LIBOR-based rates range from LIBOR plus 0.75% to LIBOR
plus 1.75% depending upon the Company meeting certain financial covenants.
Beginning September 30, 1999, the amount available under the facility begins to
reduce at three-month intervals until the termination date at September 30,
2001. The facility is collateralized by the Company's accounts and notes
receivable, common stock of its subsidiaries and partnership interests. The
Company is required to meet certain financial covenants as defined in the credit
agreement. At June 30, 1997, the Company had approximately $37.0 million
available under the revolving credit facility.
 
     At June 30, 1997, the revolving credit facility was priced at LIBOR plus
1.125%. The weighted average interest rate on the revolving credit facility was
6.81% and 6.96% at June 30, 1997 and 1996, respectively.
 
     Aggregate debt maturities for each of the years ending June 30 are as

work hours per year and have reached age 21 are eligible for admission to the
ESOP. Each participant's account vests 20% after three years of service and an
additional 20% each year thereafter.
 
EMPLOYEE STOCK PURCHASE PLAN
 
     The Company has an Employee Stock Purchase Plan (ESPP) through which
eligible employees may purchase shares of the Company's common stock, at
semi-annual intervals, through periodic payroll deductions. The ESPP is a
qualified employee benefit plan under Section 423 of the Internal Revenue Code.
The Company has reserved 150,000 shares of stock for issuance under the ESPP.
The purchase price per share will be the lower of 85% of the closing price of
the stock on the first day or the last day of the offering period or on the
nearest prior day on which trading occurred on the NASDAQ National Market
System. As of June 30, 1997, 84,891 shares of common stock have been issued
under the ESPP.

1992 STOCK OPTION PLAN
 
     The Company's 1992 Stock Option Plan was adopted in November 1992 and
provides for the granting of options to acquire common stock of the Company,
direct granting of the common stock of the Company (Stock Awards), the granting
of stock appreciation rights (SARs), or the granting of other cash awards (Cash
Awards) (Stock Awards, SARs and Cash Awards are collectively referred to herein
as Awards). At June 30, 1997, the maximum number of shares of common stock
issuable under the 1992 Plan was 3,390,750. Options may be granted as incentive
stock options or non-qualified stock options.
 
     Options and Awards may be granted only to persons who at the time of grant
are either (i) key personnel (including officers) of the Company or (ii)
consultants and independent contractors who provide valuable services to the
Company. Options that are incentive stock options may be granted only to key
personnel of the Company.
 
     The 1992 Plan, as amended, provides for the automatic grant of options to
acquire the Company's common stock (the Automatic Grant Program), whereby each
non-employee member of the Board of Directors will be granted an option to
acquire 2,500 shares of common stock annually. Each non-employee member of the
Board of Directors also will receive an annual automatic grant of options to
acquire an additional number of shares equal to 1,000 shares for each $0.05
increase in the Company's earnings per share, subject to a maximum of 5,000
additional options. New non-employee members of the Board of Directors will
receive options to acquire 10,000 shares of common stock on the date of their
first appointment or election to the Board of Directors.
 
     The expiration date, maximum number of shares purchasable and the other
provisions of the options will be established at the time of grant. Options may
be granted for terms of up to ten years and become exercisable in whole or in
one or more installments at such time as may be determined by the Plan
Administrator upon grant of the options. Options granted to date vest over
periods not exceeding five years. The exercise price of options will be
determined by the Plan Administrator, but may not be less than 100% (110% if the
option is granted to a stockholder who at the date the option is granted owns
stock possessing more than 10% of the total combined voting power of all classes
of stock of the Company or of its subsidiaries) of the fair market value of the
common stock at the date of the grant.
 
     Awards granted in the form of SARs would entitle the recipient to receive a
payment equal to the appreciation in market value of a stated number of shares
of common stock from the price stated in the award agreement to the market value
of the common stock on the date first exercised or surrendered. The Plan
Administrator may determine such terms, conditions, restrictions and/or
limitations, if any, on any SARs.
 
     The 1992 Plan states that it is not intended to be the exclusive means by
which the Company may issue options or warrants to acquire its common stock,
Awards or any other type of award. To the extent permitted by applicable law,
the Company may issue any other options, warrants or awards other than pursuant
to the 1992 Plan without shareholder approval. The 1992 Plan will remain in
force until November 5, 2002.

STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NO. 123
 
     During 1995, the FASB issued SFAS No. 123, "Accounting for Stock-Based
Compensation", which defines a fair value based method of accounting for an
employee stock option or similar equity instruments and encourages all entities
to adopt that method of accounting for all of their employee stock compensation
plans. However, it also allows an entity to continue to measure compensation
cost related to stock options issued to employees under these plans using the
method of accounting prescribed by APB Opinion No. 25, "Accounting for Stock
Issued to Employees". Entities electing to remain with the accounting in APB
Opinion No. 25 must make pro forma disclosures of net income and earnings per
share, as if the fair value based method of accounting defined in SFAS No. 123
had been applied.
 
     The Company has elected to account for its stock-based compensation plans
under APB Opinion No. 25; therefore, no compensation cost is recognized in the
accompanying financial statements for stock-based employee awards. However, the
Company has computed, for pro forma disclosure purposes, the value of all
options and ESPP shares granted during 1997 and 1996, using the Black-Scholes
option pricing model with the following weighted average assumptions:

     The effects of applying SFAS 123 for providing pro forma disclosures for
1997 and 1996 are not likely to be representative of the effects on reported net
income and earnings per common stock and common stock equivalent for future
years, because options vest over several years and additional awards are made
each year.
 
401(K) PLAN
 
     The Company has a contributory retirement plan (the 401(k) Plan) covering
eligible employees with at least one month of service. The 401(k) Plan is
designed to provide tax-deferred income to the Company's employees in accordance
with the provisions of Section 401(k) of the Internal Revenue Code.
 
     The 401(k) Plan provides that each participant may contribute up to 12% of
their respective salary, not to exceed the statutory limit. The Company may
elect to make a fixed-matching contribution to each participant's account of up
to 2% of total annual cash compensation received by respective participants
and/or a discretionary-matching contribution in an amount equal to a percentage
of the contribution made by participants as determined by the Board of
Directors. Under the terms of the 401(k) Plan, the Company may also make
discretionary profit sharing contributions. Profit sharing contributions are
allocated among participants based on their annual compensation. Each
participant has the right to direct the investment of his or her funds among
certain named plans. The Company made fixed-matching contributions to the 401(k)
Plan aggregating approximately $1,515,000 and $995,000 for the 401(k) Plan years
ended December 31, 1996 and 1995, respectively.
 
(7) STOCKHOLDERS' EQUITY
 
PREFERRED STOCK
 
     In August 1995, the Company's Board of Directors adopted a shareholder
rights plan, which authorized the distribution of one right to purchase one
one-thousandth of a share of $0.01 par value Series A Junior Participating
Preferred Stock (a Right) for each share of common stock of the Company. Rights
will become exercisable following the tenth day (or such later date as may be
determined by the Board of Directors) after a person or group (a) acquires
beneficial ownership of 15% or more of the Company's common stock or (b)
announces a tender or exchange offer, the consummation of which would result in
ownership by a person or group of 15% or more of the Company's common stock.
 
     Upon exercise, each Right will entitle the holder (other than the party
seeking to acquire control of the Company) to acquire shares of the common stock
of the Company or, in certain circumstances, such acquiring person at a 50%
discount from market value. The Rights may be terminated by the Board of
Directors at any time prior to the date they become exercisable at a price of
$0.01 per Right; thereafter, they may be redeemed for a specified period of time
at $0.01 per Right.
