APPEARING  ELSEWHERE IN THIS PROSPECTUS AND INCORPORATED INTO THIS PROSPECTUS BY

SUBSIDIARIES  AND  UNDER  AGREEMENTS  WITH  CERTAIN  PROFESSIONAL  ASSOCIATIONS.
REFERENCES IN  THIS  PROSPECTUS TO  "EMCARE"  OR  THE "COMPANY"  ARE  TO  EMCARE
HOLDINGS  INC.,  OR TO  EMCARE  HOLDINGS INC.  ALONG  WITH ITS  SUBSIDIARIES AND

                                  THE COMPANY
 
    EmCare  Holdings Inc. ("EmCare"  or the "Company") is  a leading provider of
physician practice management services in hospital emergency departments ("EDs")
and other  practice  settings.  The  Company  has  managed  emergency  physician
practices  for more than 20 years primarily in hospitals with higher volume EDs.
The Company  recruits  physicians,  evaluates their  credentials,  and  arranges
contracts  and schedules for their services.  EmCare assists in such operational
areas as staff  coordination, quality assurance  and departmental  accreditation
and  provides  billing, recordkeeping,  third-party  payment programs  and other
administrative services. The  Company markets its  services primarily to  larger
hospitals  with  EDs that  have more  than  12,000 patient  visits per  year and
multi-site systems (collectively referred to as "hospitals"). At April 30, 1996,
the Company  had management  contracts relating  to  85 EDs  in 18  states  with
approximately  2.1 million patient visits per year. EmCare also provides billing
and other physician practice management services, as well as temporary  staffing
across a broad range of medical specialties.
 
    Hospitals  have been  greatly affected  by changes  in the  U.S. health care
industry during  the  last  several  years,  including  the  increasing  use  of
capitated  and other fixed payment systems that shift financial risk from payors
to providers. The  evolving managed  care environment requires  hospitals to  be
more   cost-effective  in  all  aspects   of  their  operations,  including  the
recruiting, scheduling, retaining, and managing  of physicians, and the  billing
and  collecting for their  services. As a  result many hospitals  have turned to
outside  management  organizations  like  the  Company  for  physician  practice
management services.
 
    There  are approximately 5,200  hospitals in the  United States that operate
emergency departments.  Approximately  80%  of these  hospitals  use  outsourced
physicians  to staff their EDs.  The groups to which  ED services are outsourced
are either national groups, regional groups, or small local groups. The national
groups serve approximately 20% of the market. Approximately 40% of EDs use local
physician groups that  manage only  one or two  EDs. The  Company believes  that
these  groups are  encountering increasing  difficulty in  controlling costs and
satisfying recordkeeping and  other administrative requirements  as demanded  in
today's  evolving health care  industry. As a result,  the Company believes that
there are significant consolidation opportunities within the emergency physician
practice management industry.
 
                                    STRATEGY
 
    The  Company's  objective  is  to  continue  to  grow  as  a  high  quality,
cost-effective  provider of emergency physician  practice management services in
an increasingly competitive managed  care environment. The Company's  strategies
to achieve this objective are to:
 
    - Pursue  the  growth  of  its  physician  practice  management  business by
      acquiring  local  and  regional  groups.  These  groups  are  faced   with
      increasing   pressure  to  provide  systems  and  services  requiring  the
      resources and management expertise  of a larger organization  specializing
      in ED practice management.
 
    - Obtain  new  ED contracts  through  marketing efforts,  both  by replacing
      existing management companies and by contracting with hospitals that  have
      not previously outsourced ED practice management.
 
    - Expand  the use  of facilities  and systems  of its  higher volume  EDs to
      provide cost-effective care to patients  who require less urgent  services
      and   who   do   not   otherwise  have   access   to   a   physician.  The
 
                                       3
<PAGE>
      Company  also   has  continuing   discussions  with   health   maintenance
      organizations ("HMOs") and other managed care organizations concerning the
      use  of  EDs  to provide  medical  services to  their  participants. These
      efforts are designed  to expand  ED capabilities and  to increase  patient
      volumes.
 
    - Provide  to physicians resources  necessary to compete  in today's managed
      care  environment,  including  access  to  patients,  capital   resources,
      information  systems, and  expertise in  third-party payment  programs and
      practice management.
 
    - Utilize experience in physician practice  management to help its  hospital
      clients  control costs while providing consistent high quality care. These
      efforts include assisting  clients in  developing standardized  procedures
      and  protocols  that reduce  unnecessary  diagnostic testing  and aligning
      economic interests of physicians with the productivity of the ED.
 
                              RECENT ACQUISITIONS
 
    Consistent with  its strategic  objectives, the  Company has  completed  the
following  six significant acquisitions since January  1, 1995, for an aggregate
consideration of approximately $32.0 million and 489,688 shares of Common Stock:
 
    - On  April  30,  1996,  the  Company  acquired  Medical  Emergency  Service
      Associates (MESA), S. C. ("MESA"), a physician practice management company
      providing  ED services  to eight  hospitals and  two occupational medicine
      clinics in Illinois, with approximately  212,000 patient visits per  year.
      The  Company's  acquisition  of  MESA established  a  new  and significant
      presence for the Company in the Chicago market.
 
    - On April 1, 1996, the Company  acquired a physician practice providing  ED
      services  for  a hospital  in  Houston, Texas,  with  approximately 23,000
      patient visits per year. This acquisition expanded the Company's  presence
      in the Houston market.
 
    - On  September 7,  1995, the  Company acquired  Reimbursement Technologies,
      Inc. ("RTI"), a company  which provided billing  services to 18  emergency
      physician groups in eight states, only one of which was an existing EmCare
      group.  The Company's  acquisition of RTI  enables the  Company to perform
      internally the billing functions on  those contracts on which the  Company
      previously  used third-party billing companies. As  of April 30, 1996, the
      Company had  transferred  15  of  the  Company's  49  independent  billing
      contracts  to RTI. In addition, following this transition the Company will
      seek  to  expand  RTI's  business   of  providing  billing  services   for
      third-party clients.
 
    - On  August 1,  1995, the Company  acquired a  physician practice providing
      in-patient  physician  services  to  five  hospitals  in  Maryland,   with
      approximately  $1.9  million in  net  revenue per  year.  This acquisition
      complements the Company's acquisition of CEA in the Mid-Atlantic region of
      the United States discussed below.
 
    - On May 1,  1995, the Company  acquired a physician  practice providing  ED
      services  for a  hospital in  Arkansas, with  approximately 29,000 patient
      visits per year, which established a new presence for the Company in  that
      state.
 
    - On  February 28, 1995, the  Company acquired Capital Emergency Associates,
      P.A.  ("CEA"),  a  physician  practice  management  company  providing  ED
      services  to seven hospital  EDs in Maryland,  Virginia, and Pennsylvania,
      with approximately 208,000 patient visits per year. The acquisition of CEA
      established a significant new presence for the Company in the Mid-Atlantic
      region of the United States.

                                  RISK FACTORS
 
    IN  ADDITION TO  THE OTHER INFORMATION  IN THIS  PROSPECTUS AND INCORPORATED
INTO THIS PROSPECTUS BY  REFERENCE, THE FOLLOWING  FACTORS SHOULD BE  CONSIDERED
CAREFULLY  IN  EVALUATING THE  COMPANY AND  ITS  BUSINESS BEFORE  PURCHASING THE
SHARES OF COMMON STOCK OFFERED HEREBY.
 
ADVERSE TAX OR OTHER CONSEQUENCES IF INDEPENDENT CONTRACTOR PHYSICIANS ARE
RECLASSIFIED AS EMPLOYEES
 
    EmCare contracts  with physicians  generally as  independent contractors  to
fulfill  its contractual obligations to its  hospital clients. Since the Company
considers most  of the  physicians  with whom  it  contracts to  be  independent
contractors,  as opposed to employees, EmCare neither withholds federal or state
income or other employment related taxes nor makes federal or state unemployment
tax  or  Federal  Insurance  Contributions  Act  ("FICA")  payments  (except  as
described  below), nor provides workers'  compensation insurance with respect to
the physicians  engaged  as independent  contractors.  The Company  regards  the
payment of applicable taxes as the responsibility of such physicians. No federal
or   state  governmental  agency  has   challenged  or  accepted  the  Company's
classification of such physicians as  independent contractors except New  York's
State  Department of Labor.  As a result  of a challenge  by this agency, EmCare
pays  unemployment  tax   with  respect  to   New  York-based  physicians.   The
classification  of physicians as independent  contractors depends upon the facts
and circumstances  of the  relationship,  and there  can  be no  assurance  that
federal or state taxing authorities or other parties will not challenge EmCare's
past  or present classification of physicians and determine that such physicians
should be classified  as employees.  In the event  of a  determination that  the
physicians  engaged  as independent  contractors are  employees, EmCare  and its
operations would be  materially and adversely  affected and the  Company may  be
subject  to retroactive  taxes and penalties.  Under current federal  tax law, a
"safe harbor"  from reclassification,  and  consequently retroactive  taxes  and
penalties,  is available if the Company's current treatment is consistent with a
long-standing practice of a significant segment of the Company's industry and if
the Company meets  certain other requirements.  If challenged, there  can be  no
assurance  that the Company would prevail  in demonstrating the applicability of
the safe harbor  to its  operations. Further, proposals  have been  made in  the
recent  past, and could be made in the future, to eliminate the safe harbor. See
"Business -- Contractual Arrangements -- Physician Relationships."
 
STATE LAWS REGARDING PROHIBITION OF CORPORATE PRACTICE OF MEDICINE
 
    Business corporations such as the Company are generally not permitted  under
state  law to practice medicine, exercise  control over the medical judgments or
decisions of physicians, or engage in certain practices, such as fee  splitting,
with  physicians. The Company performs only non-medical administrative services,
does not represent to the public or its clients that it offers medical services,
and does not exercise influence or control over the practice of medicine by  the
physicians  with whom it contracts. Accordingly, the Company believes that it is
not in violation of applicable state laws relating to the practice of  medicine.
There  can be no assurance that regulatory authorities or other parties will not
assert that EmCare is engaged in the  corporate practice of medicine. If such  a
claim  were successfully asserted in  any state the Company  could be subject to
civil and criminal  penalties under such  state's law and  could be required  to
restructure  its arrangements  in that state.  Such results or  the inability to
successfully restructure contractual arrangements could have a material  adverse
effect upon the Company. See "Business -- Contractual Arrangements."
 
LITIGATION CONCERNING BILLING FOR PHYSICIAN SERVICES
 
    The  Civil Division of the U.S. Department  of Justice ("DOJ") has named the
Company as a defendant in a civil  lawsuit styled United States ex rel.  Theresa
Semtner  v.  Emergency  Physician  Billing Services,  Inc.,  et  al.  (Cause No.
94-CB-617), which was filed under seal on  April 29, 1994, in the United  States
District Court for the Western District of Oklahoma (the "DOJ Lawsuit"). In June
1995,  the DOJ informed the Company that the DOJ intended to pursue this lawsuit
against a  third-party  billing company  that  provides billing  services  on  a
contract  basis for the Company and a  number of other customers. Initially, the
DOJ agreed not  to name the  Company as a  defendant in the  lawsuit, but  later
informed  the Company that  the DOJ intended  to pursue the  lawsuit against the
Company, as  well  as  other  defendants,  unless  settlement  discussions  were
successful  by February 1, 1996.  The lawsuit was not  settled by this deadline,
and on February 1, 1996, the
 
                                       7
<PAGE>
DOJ named the Company in the lawsuit.  During the period of time covered by  the
lawsuit,  the  billing company  submitted  on behalf  of  the Company  more than
750,000 claims for payment  under Medicare, Medicaid  and CHAMPUS programs.  The
lawsuit  seeks  treble damages,  civil penalties  of $10,000  for each  claim in
question, reimbursement of costs, and such other relief as the court deems  just
and equitable.
 
    In  the lawsuit, the DOJ alleges  improper coding by the third-party billing
company of  charges  under  the  Medicare,  Medicaid  and  CHAMPUS  programs  in
violation  of the False Claims  Act, 31 U.S.C. Section3729  ET. SEQ. The billing
company has advised the  Company that it is  confident that the DOJ  allegations
are  incorrect. The Company does not currently possess sufficient information to
determine the likelihood or amount of potential liabilities relating to  alleged
improper  coding, if  any. Under  the Company's  contracts with  the third-party
billing company, the billing company has agreed to be responsible for all coding
errors. However, there is no assurance that  the Company will be able to  obtain
indemnification  from the third-party billing company for any improper coding or
that it will have the resources to honor these obligations.
 
    In addition to its allegations of improper coding, the DOJ has notified  the
Company  of  its position  that  the Company's  contracts  with the  third party
billing company fail to comply with applicable law because the billing company's
fee is  based on  a percentage  of the  amount collected.  The DOJ  has  further
notified  the Company that  the DOJ believes  that, as a  result of such alleged
illegality, each claim submitted for payment under this arrangement  constitutes
a  false  claim under  the  False Claims  Act.  The Company  believes  that such
reassignment is consistent with industry practice. Although the Company is aware
that such reassignments are  not in compliance with  applicable law relating  to
reassignment  of Medicare claims, the Company  does not believe that the failure
to comply with applicable law imposing restrictions on reassignment of  Medicare
claims renders such claims or Medicaid or CHAMPUS claims false claims within the
meaning  of the False Claims Act. If the Company does not prevail on this issue,
it is possible that the DOJ could make similar allegations with respect to:  (i)
reassignments to the third-party billing company after the period covered by the
DOJ  Lawsuit,  and  (ii)  reassignments to  the  Company's  wholly-owned billing
subsidiary. The Company is evaluating alternative billing arrangements to  avoid
this issue in the future.
 
    The  Company believes that it has various defenses to the positions taken by
the DOJ in connection with the DOJ  Lawsuit. However, there can be no  assurance
that  the outcome of the DOJ Lawsuit will  not have a material adverse effect on
the Company's financial condition and results of operations.
 
RELIANCE UPON GOVERNMENT AND OTHER PAYMENT PROGRAMS
 
    A substantial portion of patients treated by physicians under contract  with
EmCare  is covered by, and a substantial portion of the Company's net revenue is
derived  from  payments  made  by,  government-sponsored  health  care  programs
(principally  Medicare and  Medicaid). Funds  received under  these programs are
subject to audit with respect to the proper billing for physician services  and,
accordingly,  retroactive adjustments of revenue  from these programs may occur.
In late 1994, the  Health Care Financing Administration  ("HCFA"), an agency  of
the  United States government, issued  guidelines establishing new documentation
standards for Medicare and Medicaid  claims submitted for payment. Medicare  and
Medicaid  carriers began to implement the new standards on August 1, 1995, after
a grace  period which  allowed providers  to educate  themselves about  the  new
guidelines.  In addition,  a payment program  known as  "Resource Based Relative
Value Scale" ("RBRVS"), which is  intended to reallocate medical payments  among
medical  specialties, took effect  January 1, 1992  and is expected  to be fully
implemented by  December 31,  1996. The  RBRVS system  is intended  to create  a
payment  structure independent  of direct  reliance by  governmental and private
third-party payors  on hospital  costs  and physician  charges. Under  the  HCFA
guidelines  and RBRVS regulations, the aggregate  fee payments from Medicare for
certain ED procedures could adversely affect the Company's operating results and
financial condition,  especially  if  followed  by  reductions  in  payments  by
commercial  third-party payors. The Company expects  that there will continue to
be proposals to limit  payment levels by  third-party payors. Additionally,  the
health  care  industry  is  experiencing a  trend  toward  cost  containment, as
third-party payors seek to impose lower  payment rates and negotiate and  reduce
contract  rates or capitated  and other financial  risk-shifting payment systems
with service providers. The Company cannot predict at this time whether or  when
any of these proposals will be adopted or, if adopted
 
                                       8
<PAGE>
and  implemented, what affect, if any, such proposals would have on the Company.
There can  no assurance  that  payments under  governmental or  private  payment
programs will remain at levels comparable to present levels.

    Services  performed by  physicians employed  by or  under contract  with the
Company are generally charged on a  fee for service basis, and EmCare's  revenue
is  derived from such fees.  These fees are either:  (i) billed and collected by
the related  hospital,  which  remits  monthly to  EmCare  a  negotiated  amount
("hospital-based billing contracts"), or (ii) billed and collected separately by
the   Company  ("independent  billing  contracts").  Under  independent  billing
contracts the  Company  assumes  the  financial  risks  related  to  collection,
including  the potential  uncollectibility of  accounts and  delays attendant to
third-party payment programs. The percentage  of EDs under management by  EmCare
covered by independent billing contracts has increased from approximately 31% at
December  31, 1990  to approximately  58% at April  30, 1996.  Failure to manage
adequately the  collection risks  and working  capital demands  associated  with
independent  billing contracts could have an adverse effect upon the Company. In
addition, the  Company's business  could  be adversely  affected by  changes  in
patient  mix  or  volume,  payment  program  levels  and  covered  services. See
"Management's Discussion  and Analysis  of Financial  Condition and  Results  of
Operations"  and "Business -- Contractual Arrangements -- Hospital Relationships
and Billing Arrangements."
 
RISKS ASSOCIATED WITH TRANSITION TO INTERNAL BILLING
 
    Consistent with the  Company's strategy  to internally  perform its  billing
function,  the Company acquired RTI in September 1995. Effective January 1, 1996
the Company began transitioning to RTI the billing for physician services  under
its  independent  billing  contracts  on which  it  previously  used third-party
billing companies. This transition will eliminate the fee that the Company  pays
to  these third-party  billing companies for  their services. At  this time, the
Company is uncertain how the transition  will ultimately affect the revenue  per
patient  visit and  collection expenses that  the Company  realizes versus those
historically realized when using third-party billing companies. As of April  30,
1996,  the Company had transferred to RTI  the billing responsibilities on 15 of
the Company's  49 independent  billing  contracts on  which it  previously  used
third-party billing companies.
 
RISKS RELATING TO GROWTH STRATEGY
 
    EmCare's strategy involves growth, both internally and through acquisitions.
As  a result, EmCare  is subject to certain  growth-related risks, including the
risk that  it will  be unable  to retain  personnel or  acquire other  resources
necessary  to service such growth adequately. There  can be no assurance that in
the future  suitable  acquisition candidates  will  be identified  or  that  any
acquisition  will be  completed, will  be integrated  successfully into EmCare's
operations or will be successful  in achieving desired objectives for  increased
profitability.  The Company  competes against other  companies for acquisitions.
Although EmCare is  engaged in  discussions from time  to time  with respect  to
potential acquisitions, as of the date hereof there is no agreement in principle
with  respect to any material acquisition. Finally, many of the expenses arising
from EmCare's efforts to increase market penetration may have a negative  impact
on  operating results until such time as  these expenses are offset by increased
revenues. The Company's marketing activities  includes bidding on a  competitive
basis  for emergency  physician practice management  contracts. There  can be no
assurance that  any contract  obtained in  this manner  will be  profitable.  In
addition  to growth  through marketing  efforts, EmCare  intends to  continue to
pursue acquisitions of providers of ED services in connection with hospitals and
other health care institutions in complementary or related fields. There can  be
no  assurance that the Company will be  able to continue to implement its growth
strategy, or that this strategy will  ultimately be successful. See "--  Intense
Competition,"  "Use  of  Proceeds,"  "Management's  Discussion  and  Analysis of
Financial Condition  and Results  of Operations,"  "Business --  Strategy,"  and
"Business -- Marketing."
 
CUSTOMER AND GEOGRAPHIC CONCENTRATION
 
    EmCare's  two  largest ED  management  contracts, which  relate  to separate
hospital systems, accounted for  approximately 16% of  its operating revenue  in
1995.  The loss of either of these  clients could have a material adverse effect
upon the  Company. The  current  terms of  the  Company's contracts  with  these
 
                                       9
<PAGE>
hospital  systems are scheduled  to expire at  various times within  the next 20
months. There can  be no  assurance that  any contract  will be  renewed or,  if
renewed,  that  it will  contain terms  as  favorable to  EmCare as  the current
contract. In  addition, for  the  twelve months  ended  March 31,  1996,  EmCare
derived  approximately 43% of its revenue from hospitals in Texas, and hospitals
in Florida, Maryland, Illinois and Pennsylvania accounted for an additional  28%
of  EmCare's revenue, determined on a pro  forma basis as if the acquisitions of
CEA and  MESA had  occurred on  January 1,  1995. Health  care reform  or  other
developments  that adversely  affect EmCare's  operations in  these states could
have a disproportionately large effect upon  the Company. See "-- Dependence  on
Key  Personnel,  PAs  and  Qualified Physicians"  and  "Business  -- Contractual
Arrangements."
 
DEPENDENCE ON KEY PERSONNEL, PAS AND QUALIFIED PHYSICIANS
 
    The Company  is dependent  in  large part  upon  the leadership  and  active
participation  of Leonard  M. Riggs,  Jr., M.D.,  the Company's  Chairman of the
Board and Chief  Executive Officer, and  William F. Miller,  III, the  Company's
President  and  Chief  Operating Officer.  Dr.  Riggs  has more  than  a 20-year
relationship with  EmCare's largest  hospital client,  serving as  its Chief  of
Emergency Medicine and on its Medical Board for over ten years. The Company does
not  have non-compete agreements with Dr. Riggs  and Mr. Miller. The loss to the
Company of the services of Dr. Riggs or Mr. Miller, regardless of whether either
may choose to compete with  the Company, could have  an adverse effect upon  the
Company's  future  operations.  In February  1992,  the Company  entered  into a
five-year employment  contract with  each  of Dr.  Riggs  and Mr.  Miller  which
provides  inducements for their continued  active participation in the business.
The Company has  purchased key-man life  insurance on Dr.  Riggs and Mr.  Miller
providing  $2.0  million  and  $1.0  million,  respectively,  in  coverage.  See
"Management's Discussion  and Analysis  of Financial  Condition and  Results  of
Operations" and "Management."
 
    In   certain  states   the  Company  contracts   with  certain  professional
associations (the "PAs").  Where the PA  structure is utilized,  a PA  contracts
with  the hospital client and physicians  necessary to serve such hospital's ED.
Any event which has the effect of terminating or materially interfering with the
Company's relationships with  the PAs  or the PAs'  relationships with  hospital
clients  could  have  a material  adverse  effect  on EmCare.  See  "Business --
Contractual Arrangements -- PA Management Agreements."
 
    EmCare's business depends to a significant degree on its ability to  recruit
sufficient  numbers of  qualified physicians.  There currently  is a substantial
shortage of board certified emergency  medicine physicians, and EmCare  competes
with  many types  of health  care providers, as  well as  teaching, research and
governmental institutions, for the services of such physicians. There can be  no
assurance  the Company will  be able to recruit  sufficient numbers of qualified
physicians. Inability to successfully recruit physicians could adversely  affect
the  Company's ability to add new clients or lines of business. See "Business --
Contractual Arrangements."
 
INTENSE COMPETITION
 
    The provision of emergency physician practice management is characterized by
intense competition. Such competition can adversely affect the Company's  profit
margins. The Company competes with national and regional enterprises, certain of
which  have  substantially greater  financial and  other resources  available to
them. In  addition, certain  of these  firms may  have greater  access than  the
Company  to  physicians  and potential  clients.  The Company  also,  in effect,
competes against  local  ED  physician  groups  and  hospital-operated  EDs  for
satisfying  staffing and  scheduling needs. In  addition, as  EmCare pursues its
strategies  it  may  enter  other   areas  of  growing  national  and   regional
competition. See "Business -- Strategy."
 
RISK OF ADVERSE EFFECT ARISING FROM HEALTH CARE REFORM
 
    Numerous  legislative proposals have been introduced or proposed in Congress
and in  some state  legislatures that  would effect  major changes  in the  U.S.
health  care system nationally or at the  state level. Among the proposals under
consideration are  cost  controls  on hospitals,  insurance  market  reforms  to
increase  the  availability  of  group  health  insurance  to  small businesses,
requirements  that  all  business  offer  health  insurance  coverage  to  their
employees  and the  creation of a  single government health  insurance plan that
would cover all citizens. It  is not clear at this  time what proposals will  be
adopted,  if any, or, if adopted, what effect, if any, such proposals would have
on   EmCare's    business.   Certain    proposals,   such    as   cutbacks    in
 
                                       10
<PAGE>
the  Medicare  and Medicaid  programs, containment  of health  care costs  on an
interim basis by means that could include a short-term freeze on prices  charged
by physicians, hospitals and other health care providers, and permitting greater
state  flexibility  in the  administration of  Medicaid, could  adversely affect
EmCare. There can be no assurance that currently proposed or future health  care
legislation  or  other  changes  in  the  administration  or  interpretation  of
governmental health care programs will not have an adverse affect on EmCare. See
"-- Reliance Upon Government and Other Payment Programs."
 
PROFESSIONAL AND GENERAL LIABILITIES
 
    The Company  periodically  becomes  involved  in  professional  and  general
liability  claims with the attendant risk of substantial damage awards. The most
significant source of potential  liability in this regard  is the negligence  of
physicians   under  contract  with  the   Company.  The  Company  performs  only
non-medical administrative services,  does not  represent to the  public or  its
clients  that  it offers  medical services  and does  not exercise  influence or
control over the  practice of  medicine by  physicians with  whom it  contracts.
However,  it could be  asserted that the  Company should be  held liable for any
malpractice of  its independent  contractor physicians  under various  theories,
including  theories that an  independent contractor physician  is an employee or
agent of the Company or that the Company was negligent in contracting with  such
physician.  Additionally, the Company's  contracts with certain  of its hospital
clients require  the  Company to  indemnify  the hospital  for  losses  suffered
thereby, including losses resulting from a physician's malpractice. There can be
no  assurance  that  a future  claim  or claims  will  not be  successful  or if
successful will not exceed  the limits of available  insurance coverage or  that
such  coverage will continue to be  available at acceptable costs. See "Business
- -- Emergency Physician Practice Management -- Recruiting and Credentialing."
 
ANTI-TAKEOVER PROVISIONS
 
    The Company's certificate  of incorporation and  by-laws contain  provisions
that  may make  it more  difficult for a  third-party to  acquire, or discourage
acquisition bids for, the Company. These  provisions could limit the price  that
certain  investors might be  willing to pay  in the future  for shares of Common
Stock. See "Description of Capital Stock."

                                USE OF PROCEEDS
 
    The net proceeds to the  Company of the sale  of 1,500,000 shares of  Common
Stock  offered hereby by the Company, assuming a public offering price of $31.25
per share, are estimated to be approximately $44.1 million ($50.9 million if the
Underwriters exercise their over-allotment option from the Company in full). The
Company expects  to use  approximately $12.0  million to  repay the  outstanding
balance  under its bank credit facility (the "Credit Facility"), $2.5 million to
complete the  development  and implementation  of  a customized  ED  information
system,  and the balance of the net proceeds, together with borrowings under the
Credit Facility, to make acquisitions.  The amount outstanding under the  Credit
Facility  as of May  31, 1996 was  $12.0 million, which  the Company incurred in
connection with  acquisitions.  Such amount  bears  interest at  variable  rates
(approximately  6% at May 31,  1996) and is payable  on February 20, 1999. Until
used, the  Company's  net  proceeds  from this  offering  will  be  invested  in
short-term,  investment grade,  interest-bearing obligations.  See "Management's
Discussion and  Analysis  of Financial  Condition  and Results  of  Operations,"
"Business -- Strategy," and "Business -- Information Systems."
 
                          PRICE RANGE OF COMMON STOCK
 
    The  Company  completed  its  initial public  offering  of  Common  Stock in
December 1994  at an  initial public  offering price  of $11.00  per share.  The
Common  Stock began trading on the Nasdaq  National Market under the symbol EMCR
on December 8, 1994. The table below sets forth the high and low sale prices for
the Common Stock on the Nasdaq National Market during the periods indicated.

                                DIVIDEND POLICY
 
    Since its initial public offering, the Company has not declared or paid, nor
does it currently intend to declare or pay, cash dividends on the Common  Stock,
but  intends  instead to  retain  any future  earnings  for reinvestment  in its
business. In addition,  the Credit  Facility prohibits the  Company from  paying
dividends and restricts the ability of the Company's subsidiaries and the PAs to
pay  dividends or make distributions.  See "Management's Discussion and Analysis
of Financial  Condition  and Results  of  Operations" and  Note  5 of  Notes  to
Consolidated Financial Statements of the Company.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
INTRODUCTION
 
    The  Company is a leading provider of physician practice management services
in hospital EDs and other practice settings. The Company recruits and  evaluates
the  credentials of  physicians and arranges  contracts and  schedules for their
services. The Company has managed emergency physician services for more than  20
years primarily in larger hospitals with high volume EDs. At April 30, 1996, the
Company  had  management  contracts  relating  to  85  EDs  in  18  states  with
approximately 2.1 million patient visits per year. In addition to the  Company's
emergency physician practice management, the Company provides physician practice
management  for  hospital-based  radiology,  intensive  care  and  lower  volume
emergency medicine practices,  and for primary  care physician group  practices.
The  Company  also provides  billing services  for emergency  physician practice
management contracts and provides physician  placement services, primarily on  a
LOCUM TENENS (temporary) basis, across a broad range of practice specialties.
 
    Revenue is recorded in the period the services are rendered as determined by
the  respective contracts with the  health care providers. Professional expenses
are based on the terms of the respective contracts with the physicians. Services
performed by physicians under contract with the Company are generally charged on
a fee for service basis,  and the Company's revenue  is derived from such  fees.
These  fees are either:  (i) collected by  the related hospital,  which remits a
negotiated  amount  monthly  to  the  Company,  or  (ii)  billed  and  collected
separately  by  the Company  ("independent  billing contracts").  In independent
billing contract  arrangements, the  Company  arranges for  third-party  billing
firms or a subsidiary to bill and collect directly for services performed by the
physicians. Cost of collections is included in professional expense.
 
    The  table below sets forth for the  periods indicated the percentage of net
revenue  contributed  by  emergency  physician  practice  management  and  other
services.

    Management  believes  its emergency  physician practice  management business
should continue to realize steady internal growth. Also, the emergency physician
practice  management  business   is  highly   fragmented  and   the  market   is
consolidating.  Accordingly, acquisitions  have been  a significant  part of the
Company's growth in the past and the  Company intends to continue to expand  its
business  through acquiring local and regional groups with high volume contracts
and favorable demographics.
 
    The Company's future results  of operations will depend  in a large part  on
the  Company's ability to: (i) continue to acquire physician practice management
companies on  attractive terms  and  to successfully  integrate and  manage  the
acquired  operations, (ii) to obtain new emergency physician practice management
contracts on attractive terms and to successfully operate under such  contracts,
and  (iii)  to  increase  revenues  on  existing  emergency  physician  practice
management contracts. There  can be  no assurance  that in  the future  suitable
acquisition  candidates  will  be identified  or  that any  acquisition  will be
completed, will be integrated successfully into the Company's operations or will
be successful  in  achieving  desired objectives  for  increased  profitability.
Furthermore,  there can be no  assurance that the Company  will be successful in
bidding for and obtaining new contracts,  that it will operate profitably  under
any  new contracts,  or that  it will  be able  to increase  revenue on existing
contracts. See "Risk Factors -- Risks Relating to Growth Strategy."

THREE MONTHS ENDED MARCH 31, 1996 AS COMPARED TO THREE MONTHS ENDED MARCH 31,

    NET REVENUE.  Net revenue increased $9.7 million, or 28.1%, to $44.2 million
for  the three  months ended  March 31,  1996 from  $34.5 million  for the three
months ended March 31, 1995. Of this increase, $7.7 million was attributable  to
increased  revenue  from  the Company's  ED  contracts. Net  revenue  from other
services  increased  $2.0  million,  contributing   5.8%  to  the  28.1%   total
period-to-period  increase. This  consists of  $1.4 million  attributable to the
Company's billing company which was acquired  in September 1995, an increase  of
$653,000  attributable  to the  Company's management  of primary  care physician
group practices,  and  a  decrease  of  $65,000  attributable  to  other  non-ED
services.
 
    Same  store ED  contract revenue increased  $1.9 million, or  6.7%, to $30.2
million for the three  months ended March  31, 1996 from  $28.3 million for  the
three  months  ended  March  31,  1995, contributing  5.5%  to  the  28.1% total
period-to-period increase. "Same store" revenue consists of revenue derived from
EDs under management from the beginning of  the prior period through the end  of
the  subsequent period.  New ED contracts  generated by  the Company's marketing
activities contributed $3.8 million of the increase in net revenue, or 11.0%  to
the 28.1% total period-to-period increase. Acquisitions contributed $3.6 million
of  the increase in  net revenue, or  10.4% to the  28.1% total period-to-period
increase. Included in the period-to-period increase in net revenue is a negative
impact of $1.6  million, or 4.6%  to the 28.1%  total period-to-period  increase
caused by the loss of contracts.
 
    PROFESSIONAL EXPENSES.  Professional expenses primarily consist of fees paid
to  physicians  under contract  with the  Company,  collection fees  relating to
independent billing  contracts billed  by vendors,  operating expenses  for  the
billing  company, and  professional liability insurance  premiums for physicians
under contract. Professional expenses  increased by $8.1  million, or 30.1%,  to
$35.3  million for the three months ended  March 31, 1996 from $27.2 million for
the  three  months   ended  March   31,  1995.  This   increase  was   primarily
 
                                       16
<PAGE>
attributable  to the  addition of  new ED  contracts. Expenses  related to other
services increased $1.9 million  from period to  period, including $1.3  million
related  to  the  acquired billing  company.  As  a percentage  of  net revenue,
professional expenses increased  to 79.8% in  the three months  ended March  31,
1996  from  78.6% in  the  same period  in  1995. The  increase  in professional
expenses as a percentage of net revenue is primarily due to the operating  costs
associated with the billing company acquired in September 1995.
 
    GENERAL  AND ADMINISTRATIVE  EXPENSES.  General  and administrative expenses
increased by $318,000, or 8.1%, to $4.2 million for the three months ended March
31, 1996 from  $3.9 million  for the  three months  ended March  31, 1995.  This
increase  is  primarily  attributable to  the  incremental  administrative costs
related to the new EDs under management. As a percentage of net revenue, general
and administrative expenses decreased  to 9.6% in the  three months ended  March
31,  1996 from  11.4% in  the same period  in 1995  as the  Company continues to
leverage its infrastructure with greater revenue growth.
 
    DEPRECIATION  AND  AMORTIZATION.    Depreciation  and  amortization  consist
principally   of  amortization   of  goodwill,   contracts  and  non-competition
agreements entered into in  connection with business acquisitions.  Depreciation
and  amortization increased  by $404,000,  or 99.8%,  to $809,000  for the three
months ended March 31, 1996 from $405,000  for the three months ended March  31,
1995, principally due to business acquisitions.
 
    INTEREST  INCOME/EXPENSE.  Interest expense  increased by $26,000, or 17.8%,
to $172,000 for  the three months  ended March  31, 1996 from  $146,000 for  the
three  months ended  March 31, 1995.  Interest income decreased  by $272,000, or
79.1%, to $72,000 for the  three months ended March  31, 1996 from $344,000  for
the  three months  ended March  31, 1995, primarily  due to  lower cash balances
available for investment in the first quarter of 1996. Cash balances were higher
in the  first quarter  of  1995 as  a result  of  the Company's  initial  public
offering in December 1994.
 
    INCOME  TAXES.  The Company's effective tax rate remained unchanged at 38.0%
from period to period.
 
YEAR ENDED DECEMBER 31, 1995 AS COMPARED TO YEAR ENDED DECEMBER 31, 1994
 
    NET REVENUE.   Net  revenue increased  $38.5 million,  or 32.6%,  to  $156.8
million  for the year ended  December 31, 1995 from  $118.3 million for the year
ended December 31,  1994. Of this  increase, $35.2 million  was attributable  to
increased  revenue  from  the Company's  ED  contracts. Net  revenue  from other
services  increased  $3.3  million,  contributing   2.8%  to  the  32.6%   total
period-to-period  increase. This  consists of  $2.0 million  attributable to the
Company's acquired billing company, an increase of $1.1 million attributable  to
the  Company's  management  of primary  care  physician group  practices,  and a
decrease of $200,000 attributable to other non-ED services.
 
    Same store ED contract  revenue increased $8.4 million,  or 9.1%, to  $100.9
million  for the year  ended December 31,  1995 from $92.5  million for the year
ended December 31, 1994, contributing  7.1% to the 32.6% total  period-to-period
increase.  New  ED contracts  generated  by the  Company's  marketing activities
contributed $15.3 million of the increase in net revenue, or 12.9% to the  32.6%
total  period-to-period increase. Acquisitions contributed  $17.5 million of the
increase in net revenue, or 14.8% to the 32.6% total period-to-period  increase.
Included in the period-to-period increase in net revenue is a negative impact of
$6.0  million, or 5.1%  to the 32.6% total  period-to-period increase, caused by
the loss of contracts.
 
    PROFESSIONAL EXPENSES.  Professional expenses primarily consist of fees paid
to physicians  under contract  with  the Company,  collection fees  relating  to
independent  billing  contracts billed  by vendors,  operating expenses  for the
newly acquired billing  company, and professional  liability insurance  premiums
for physicians under contract. Professional expenses increased by $29.7 million,
or  31.6%, to  $123.9 million for  the year  ended December 31,  1995 from $94.2
million for  the year  ended  December 31,  1994.  This increase  was  primarily
attributable  to the  addition of new  ED contracts. Expenses  relating to other
services increased by $3.6 million from period to period, including $2.1 million
related to  the  acquired billing  company.  As  a percentage  of  net  revenue,
professional  expenses decreased  to 79.0% in  the year ended  December 31, 1995
from 79.6% in the same period in 1994.
 
                                       17
<PAGE>
    GENERAL AND ADMINISTRATIVE  EXPENSES.  General  and administrative  expenses
increased  by  $3.2 million,  or  23.4%, to  $16.8  million for  the  year ended
December 31, 1995 from $13.6 million for the year ended December 31, 1994.  This
increase  is  primarily  attributable to  the  incremental  administrative costs
related to the new EDs under management. As a percentage of net revenue, general
and administrative expenses decreased from 11.5% in the 1994 period to 10.7%  in
the  1995 period  as the Company  continues to leverage  its infrastructure with
greater revenue growth.
 
    DEPRECIATION  AND  AMORTIZATION.    Depreciation  and  amortization  consist
principally   of  amortization  of   goodwill,  contracts,  and  non-competition
agreements entered into in  connection with business acquisitions.  Depreciation
and  amortization increased by $1.1  million, or 74.7%, to  $2.5 million for the
year ended December 31, 1995 from $1.4  million for the year ended December  31,
1994, principally due to the acquisitions.
 
    INTEREST  INCOME/EXPENSE.   Interest expense  decreased by  $1.6 million, or
72.7%, to $652,000 for the  year ended December 31,  1995 from $2.2 million  for
the  year ended  December 31,  1994, principally due  to the  repayment of $14.5
million of  subordinated debt  in December  1994. Interest  income increased  by
$602,000,  or  182%, to  $933,000  for the  year  ended December  31,  1995 from
$331,000 for the  year ended  December 31, 1994,  primarily due  to higher  cash
balances  available for investment  as a result of  the Company's initial public
offering in December 1994 and higher interest rates applicable to invested cash.
 
    INCOME TAXES.  The Company's effective  tax rate increased to 37.5% for  the
year  ended December 31, 1995 from 36% for the year ended December 31, 1994, due
principally to non-deductible amortization expense arising from acquisitions.
 
YEAR ENDED DECEMBER 31, 1994 AS COMPARED TO YEAR ENDED DECEMBER 31, 1993
 
    NET REVENUE.   Net  revenue increased  $22.5 million,  or 23.4%,  to  $118.3
million  for the year  ended December 31,  1994 from $95.8  million for the year
ended December 31,  1993. Of this  increase, $21.9 million  was attributable  to
increased  revenue  from  the Company's  ED  contracts. Net  revenue  from other
services increased $576,000 from period to  period which was principally due  to
an  increase  of $1.3  million  attributable to  the  Company's management  of a
primary care  physician  group practice  which  commenced  in June  1993  and  a
decrease of $705,000 attributable to other non-ED services.
 
    Same  store ED  contract revenue increased  $4.9 million, or  6.3%, to $82.9
million for the year  ended December 31,  1994 from $78.0  million for the  year
ended  December 31, 1993, contributing 5.1%  to the 23.4% total period-to-period
increase. New  ED  contracts generated  by  the Company's  marketing  activities
contributed  $12.1 million of the increase in net revenue, or 12.6% to the 23.4%
total period-to-period increase.  Acquisitions contributed $7.3  million of  the
increase  in net revenue, or 7.6%  to the 23.4% total period-to-period increase.
Included in the period-to-period increase in net revenue is a negative impact of
$2.4 million, or 2.5%  to the 23.4% total  period-to-period increase, caused  by
the loss of contracts.
 
    PROFESSIONAL EXPENSES.  Professional expenses primarily consist of fees paid
to  physicians  under contract  with the  Company,  collection fees  relating to
independent billing contracts and professional liability insurance premiums  for
physicians  under contract. Professional expenses increased by $18.4 million, or
24.3%, to $94.2 million for the year ended December 31, 1994 from $75.8  million
for  the year ended December 31,  1993. This increase was primarily attributable
to the addition of  new ED contracts and  professional expenses relating to  the
Company's  management of a  primary care physician  group practice. Professional
expenses relating to  other services  were relatively unchanged  from period  to
period.
 
    GENERAL  AND ADMINISTRATIVE  EXPENSES.  General  and administrative expenses
increased by  $1.4  million, or  11.2%,  to $13.6  million  for the  year  ended
December  31, 1994  from $12.2  million for  the year  ended December  31, 1993.
Beginning in 1992, the Company invested significant resources in the development
of its  management  and  marketing infrastructure  designed  to  facilitate  and
accommodate  future growth.  These activities  continued through  1993, and 1994
bears the full impact of the  costs associated with these enhancements.  General
and  administrative  expenses for  the year  ended December  31, 1993  include a
non-recurring
 
                                       18
<PAGE>
$600,000 charge for compensation expense relating to contingent payments made to
selling  stockholders  in  a  business   acquisition  completed  in  1992.   The
incremental  administrative costs related  to the new  EDs under management also
contributed to  the  period-to-period  increase in  general  and  administrative
expenses.
 
    DEPRECIATION  AND  AMORTIZATION.    Depreciation  and  amortization consists
principally  of  amortization   of  goodwill,   contracts  and   non-competition
agreements  entered  into  in  connection  with  business  acquisitions  and  in
connection with the recapitalization  of the Company  in 1992. Depreciation  and
amortization  decreased by $4.4 million, or 75.5%,  to $1.4 million for the year
ended December 31, 1994 from $5.8 million for the year ended December 31,  1993.
This  decrease resulted  primarily from  the elimination  in the  1994 period of
amortization expense relating to the  non-competition agreements written off  in
the fourth quarter of 1993.
 
    INTEREST  INCOME/EXPENSE.   Interest  expense, net  of interest  income, was
relatively unchanged from period to period.
 
    INCOME TAXES.  The Company's effective  tax rate decreased to 36.0% for  the
year ended December 31, 1994 from 39.4% for the year ended December 31, 1993 due
to a reorganization of its subsidiaries to achieve state tax savings.

LIQUIDITY AND CAPITAL RESOURCES
 
    At March 31,  1996, the  Company had $22.7  million in  working capital,  an
increase  of  $3.8  million from  December  31,  1995. At  March  31,  1996, the
Company's  principal  sources   of  liquidity   consisted  of:   (i)  cash   and
 
                                       19
<PAGE>
cash  equivalents aggregating  $7.1 million,  (ii) accounts  receivable totaling
$31.0 million, and (iii)  $47.0 million in borrowing  capacity under its  Credit
Facility.  Subsequent to March 31,  1996, the Company acquired  MESA for a total
purchase price  of $11.1  million,  including $7.8  million borrowed  under  the
Credit  Facility and 56,355 shares of Common Stock valued at $1,500,000, assumed
short and long-term obligations of $866,000, and additional consideration of  up
to  $2,000,000 payable within the next  three years if certain financial targets
are attained. See "Business -- Recent Acquisitions."
 
    In the three months ended March 31,  1996, $4.9 million in cash was used  to
support  operating  activities. This  amount reflects  the increase  in accounts
receivable due to growth in the number of EDs, an increase in prepaid insurance,
and a decrease in  accounts payable and accrued  expenses. Cash of $724,000  was
provided  by investing activities for  the three months ended  March 31, 1996 as
the proceeds from  the sale of  marketable securities exceeded  the purchase  of
furniture  and office equipment. Cash of  $3.5 million was provided by financing
activities for the three months ended March 31, 1996 as proceeds from borrowings
and the exercise of stock options exceeded payments on obligations.
 
    Accounts receivable are a  key component of  the Company's working  capital.
Accounts receivable totaled $31.0 million at March 31, 1996, an increase of $1.2
million over December 31, 1995. The timing of payments on the Company's accounts
receivable can vary significantly depending on whether the related contract is a
hospital-based  or independent billing contract. Independent billing receivables
have  a  significantly  longer  collection  cycle  than  hospital-based  billing
receivables  because of the  process of billing  and collecting from third-party
payor programs  and  private payors.  The  number  of days  revenue  in  average
receivables  was 63 days for the three  months ended March 31, 1996, compared to
61 days  for  the  three  months  ended  March  31,  1995.  In  connection  with
independent  billing contracts, the  Company incurs, and can  expect to incur in
the future, negative cash flow during  the start-up phase (typically six  months
or more after the contract is initiated).
 
    On  February 20,  1996, the Company  replaced its credit  agreement with the
Credit Facility, a revolving line of credit with a bank acting as administrative
agent for a syndicate of lenders under which the Company can borrow up to  $50.0
million  for  working  capital  and acquisition  purposes.  The  Credit Facility
matures on February 20, 1999. Borrowings under the Credit Facility bear interest
at variable rates based, at the Company's option, on the bank's base rate or the
Eurodollar rate. As  of April 30,  1996, $38.0 million  was available under  the
Credit Facility.
 
    The  Company  currently  procures  and partially  finances,  and  expects to
continue to procure and partially  finance, professional liability insurance  on
behalf  of most physicians  under contract with the  Company. The current policy
expires December 31, 1997.
 
    The Company's  annual  capital expenditures  have  typically been  for  data
processing  equipment  and  leasehold improvements  at  the  Company's corporate
offices. Capital expenditures of $919,000 in 1995 are a result of the  Company's
commitment  to significantly enhance its information systems. In the foreseeable
future, annual capital expenditures are not expected to exceed $2.5 million  per
year.
 
    The  Company anticipates that funds generated from operations, together with
funds available  under the  Credit  Facility, will  be  sufficient to  meet  its
working  capital requirements and debt obligations  and to finance any necessary
capital expenditures  for the  foreseeable future.  Expansion of  the  Company's
business through acquisitions may require additional funds, which, to the extent
not  provided by internally generated sources,  the Credit Facility, and the net
proceeds of this offering, would require the Company to seek additional debt  or
equity financing.
 
INFLATION
 
    The  Company's  business  is  labor  intensive  with  extensive  reliance on
independent contractor physicians. Fees paid to such physicians tend to increase
during periods  of inflation  and  when shortages  in  the labor  market  occur.
Because  of restrictions on payment by  government and private medical insurance
programs and the pressures to contain the growth in the costs of such  programs,
the Company bears the risk that payment rates set by such programs will not keep
pace  with inflation. Although the moderate  inflation rates of the past several
years have  not  posed  significant  problems for  the  Company,  a  substantial
increase  in the rate  of inflation without a  corresponding increase in payment
rates would adversely affect the Company's business.

                                    BUSINESS
 
    The  Company  is  a leading  provider  of physician  practice  management in
hospital EDs  and other  practice settings.  The Company  has managed  emergency
physician  practices for more  than 20 years primarily  in hospitals with higher
volume EDs. The  Company recruits physicians,  evaluates their credentials,  and
arranges  contracts and  schedules for  their services.  EmCare assists  in such
operational areas  as staff  coordination,  quality assurance  and  departmental
accreditation  and provides billing, recordkeeping, third-party payment programs
and other administrative services. The Company markets its services primarily to
hospitals with  EDs that  have more  than  12,000 patient  visits per  year  and
multi-site  systems. At  April 30,  1996, the  Company had  management contracts
relating to 85 EDs  in 18 states with  approximately 2.1 million patient  visits
per  year. EmCare also provides billing  and other physician practice management
services, as  well  as  temporary  staffing across  a  broad  range  of  medical
specialties.
 
MARKET OVERVIEW
 
    Hospitals  have been  greatly affected  by changes  in the  U.S. health care
industry during  the  last  several  years,  including  the  increasing  use  of
capitated  and other fixed payment systems that shift financial risk from payors
to providers. The  evolving managed  care environment requires  hospitals to  be
more   cost-effective  in  all  aspects   of  their  operations,  including  the
recruiting, scheduling, retaining  and managing of  physicians, and billing  and
collecting for their services. As a result many hospitals have turned to outside
management  organizations  like the  Company  for physician  practice management
services.
 
    There are approximately 5,200  hospitals in the  United States that  operate
emergency  departments.  Approximately  80% of  these  hospitals  use outsourced
physicians to  staff  their EDs.  The  outsourcing  groups used  to  provide  ED
services are either national groups, regional groups, or small local groups. The
national  groups serve approximately 20% of the market. Approximately 40% of EDs
use local physician groups that manage only one or two EDs. The Company believes
that these groups are encountering  increasing difficulty controlling costs  and
satisfying  recordkeeping and  other administrative requirements  as demanded in
today's evolving health care  industry. As a result,  the Company believes  that
there are significant consolidation opportunities within the emergency physician
practice management industry.
 
    EDs  are typically the  hospital's most visible operation  to the public and
generate, on average,  approximately 40%  of inpatient  admissions. The  Company
believes  that EDs will continue to be  essential to serve the health care needs
of the public in cases of unpredictable, acute and serious trauma and illness.
 
    Emergency physicians  act  as  primary  care  physicians  both  to  patients
requiring  emergency  services and  to patients  who are  less seriously  ill or
injured and who do not  otherwise have access to  a physician. Utilizing the  ED
for  treatment of  less seriously  ill or  injured patients  is perceived  to be
inefficient, however,  and health  care organizations  such as  the Company  are
increasingly  developing primary care facilities within  or contiguous to the ED
so that  these patients  can be  seen  in a  more cost-effective  setting  while
maximizing the utilization of the ED's resources. The Company believes that with
proper  procedures, staffing, and configuration,  EDs can provide cost effective
primary care while maintaining their essential emergency care function.
 
    In addition  to  hospitals, the  market  for physician  practice  management
includes  integrated health care delivery  and financing systems. These systems,
which include HMOs and other third-party payors, large employers, and  hospitals
in various combinations, must address the same issues of recruiting, scheduling,
and  managing physicians that hospitals face  in managing their EDs. The Company
believes that these  systems will  increasingly turn  to outside  organizations,
either  on an outsource  or joint venture  basis, to arrange  for and manage the
professional component of their services.
 
    Changes in the U.S.  health care industry are  also eroding the  traditional
relationship  between  private  practitioners,  physicians  and  their patients.
Increasing practice complexity  and costs, together  with declining per  patient
revenues  resulting  from  new  payment  systems  and  declining  patient volume
resulting from steerage  of patients  to HMOs and  other groups,  have led  many
physicians  to affiliate themselves with organizations such as the Company which
can provide the capital resources, information and payment systems and  practice
management expertise that physicians need in today's environment.

STRATEGY
 
    The  Company's  objective  is  to  continue  to  grow  as  a  high  quality,
cost-effective provider of emergency  physician practice management services  in
an  increasingly competitive managed care  environment. The Company's strategies
to achieve this objective are:
 
    GROWTH THROUGH ACQUISITION.  The Company  intends to continue to pursue  the
growth  of its  physician practice  management business  by acquiring  local and
regional groups.  These groups  are faced  with increasing  pressure to  provide
systems  and  services requiring  the resources  and  management expertise  of a
larger organization  specializing in  outsourced  ED practice  management.  From
January  1992  through April  1996  the Company  added  28 EDs  and  seven other
practice  settings  through  acquisitions.  See  "Management's  Discussion   and
Analysis of Financial Condition and Results of Operations."
 
    GROWTH THROUGH MARKETING.  Through marketing efforts, EmCare seeks to obtain
new contracts both by replacing existing management companies and by contracting
with  hospitals that have not previously  outsourced ED practice management. The
Company markets its services primarily to  hospitals with higher volume EDs  and
multi-site  systems. From January  1992 through April 1996  the Company added 32
EDs through its marketing efforts.
 
    EXPAND SERVICES OF ED FACILITIES.  EmCare will expand the use of  facilities
and  systems of its higher volume EDs to provide cost-effective care to patients
who require less  urgent services  and who  do not  otherwise have  access to  a
physician.  The Company  intends to continue  to assist its  hospital clients to
establish "express care units" within or in conjunction with their EDs to permit
more cost-effective  treatment of  lower acuity  ED patients.  In addition,  the
Company is continuing discussions with HMOs and other managed care organizations
concerning  the use  of EDs to  provide medical services  to their participants.
These efforts are  designed to expand  ED capabilities and  to increase  patient
volume.
 
    ASSIST PHYSICIANS IN A MANAGED CARE ENVIRONMENT.  EmCare provides physicians
with  the resources  necessary to compete  in today's  managed care environment,
including access to patients, as well as capital resources, information systems,
and expertise in  third-party payment  programs and  practice management.  These
advantages enhance EmCare's ability to retain high quality physicians.
 
    ASSIST  CLIENTS TO  CONTROL COSTS.   The Company utilizes  its experience in
physician practice management to help  its hospital clients control costs  while
providing  consistent high quality  care. In addition  to the economies obtained
from expanding  the  uses of  ED  facilities, these  efforts  include  assisting
clients   in  developing  standardized  procedures  and  protocols  that  reduce
unnecessary diagnostic testing and compensating physicians in part based on  the
performance  of the ED, thereby aligning the economic interests of the physician
with the productivity of the ED.
 
RECENT ACQUISITIONS
 
    Consistent with  its strategic  objectives, the  Company has  completed  the
following  six significant acquisitions  since January 1,  1995 for an aggregate
consideration of approximately $32.0 million and 489,688 shares of Common Stock.
 
    - On April  30,  1996,  the  Company acquired  MESA,  a  physician  practice
      management  company  providing  ED  services to  eight  hospitals  and two
      occupational medicine  clinics  in Illinois,  with  approximately  212,000
      patient  visits per year. The Company's  acquisition of MESA established a
      new and significant presence for the Company in the Chicago area.
 
    - On April 1, 1996, the Company  acquired a physician practice providing  ED
      services  for  a hospital  in  Houston, Texas,  with  approximately 23,000
      patient visits per year. This acquisition expanded the Company's  presence
      in the Houston market.
 
    - On  September 7, 1995, the Company  acquired RTI, a company which provided
      billing services to 18  emergency physician groups  in eight states,  only
      one  of which was  an existing EmCare group.  The Company's acquisition of
      RTI enables  it  to perform  internally  the billing  functions  on  those
      contracts  on  which  the  Company  previously  used  third-party  billing
      companies. As of April 30, 1996, the
 
                                       22
<PAGE>
      Company had  transitioned  15  of the  Company's  49  independent  billing
      contracts  to RTI. In addition, following this transition the Company will
      seek  to  expand  RTI's  business   of  providing  billing  services   for
      third-party clients.
 
    - On  August 1,  1995, the Company  acquired a  physician practice providing
      inpatient  physician  services  to   five  hospitals  in  Maryland,   with
      approximately  $1.9  million in  net  revenue per  year.  This acquisition
      complements the Company's acquisition of CEA in the Mid-Atlantic region of
      the United States discussed below.
 
    - On May 1,  1995, the Company  acquired a physician  practice providing  ED
      services  for a  hospital in  Arkansas, with  approximately 29,000 patient
      visits per year, which established a new presence for the Company in  that
      state.
 
    - On  February  28, 1995,  the Company  acquired  CEA, a  physician practice
      management  company  providing  ED  services  to  seven  hospital  EDs  in
      Maryland,  Virginia, and Pennsylvania,  with approximately 208,000 patient
      visits per  year. The  acquisition of  CEA established  a significant  new
      presence for the Company in the Mid-Atlantic region of the United States.
 
EMERGENCY PHYSICIAN PRACTICE MANAGEMENT
 
    EmCare's  principal activity  is providing physician  practice management to
EDs. The  Company  generally  is  responsible  for  recruiting,  evaluating  the
credentials  of  and  scheduling qualified  emergency  physicians  and providing
administrative support  for the  hospital and  the physicians.  The ED  coverage
provided  by the Company generally includes  scheduling a group of physicians to
be on  duty on  a 24-hour,  365-day  basis. As  of April  30, 1996,  EmCare  had
contracts  to provide  physician practice management  in 85  EDs. These services
accounted for approximately 92%  of the Company's total  net revenue during  the
twelve months ended March 31, 1996.
 
    RECRUITING  AND CREDENTIALING.  Recruiting and evaluating the credentials of
physicians are  essential  services provided  by  the Company  to  its  hospital
clients.  EmCare commences its  recruiting process by  contacting physicians who
reside in or near  the location involved  or who have  expressed an interest  in
relocating  there  and by  mailing opportunity  bulletins to  a larger  group of
physicians residing in adjacent areas. It then prescreens responses to determine
whether the candidates meet the qualifications established by the hospital.  The
Company  verifies the  licensing, training  and professional  references of each
remaining candidate.  After this  qualification  process, the  Company  arranges
interviews for the physician with hospital personnel and visits to the community
by  the physician to ensure professional and personal compatibility. The Company
is responsible for supervising all arrangements relating to the commencement  of
the physician's services, including relocation, if necessary.
 
    The  Company's hospital clients  generally stipulate in  their contracts the
minimum number of board certified or board eligible physicians required to serve
in the  client's ED.  Approximately 92%  of the  full-time ED  physicians  under
contract with EmCare are board certified or board eligible in emergency medicine
or  other  relevant  medical specialties  such  as internal  medicine  or family
practice.
 
    SUPPORT SERVICES.  The  Company provides a broad  range of support  services
and  resources  to hospitals  and  physicians. These  services  include billing,
accounting, recordkeeping and  other administrative services.  In addition,  the
Company  assists its  hospital clients  in dealing  with more  general concerns,
including fiscal constraints, marketing of the ED  and use of EDs as sources  of
primary  medical  care.  The  Company  also  assists  its  hospital  clients  in
negotiations with HMOs and  other managed care  organizations when capitated  or
other risk-shifting payment models are involved.
 
    EmCare  contracts with  a physician  at each  ED to  be its  on-site medical
director. This  physician plays  a  key role  in  coordinating the  delivery  of
EmCare's  services and  integrating the  Company's services  with the hospital's
operations. The medical director  also works with  the hospital's medical  staff
and  administration  in such  areas as  quality  assurance, risk  management and
departmental accreditation.
 
    Through the medical director, the  Company also assists the hospital  client
develop  clinical  protocols  designed  to  provide  consistent  diagnostic  and
treatment methodologies for ED patients, thereby facilitating
 
                                       23
<PAGE>
the delivery  of high  quality medical  care on  a cost-effective  basis.  These
protocols,  such as the  types of laboratory tests  routinely given for patients
with specific  symptoms,  must  be  developed with  the  medical  staff  at  the
particular  hospital,  and consequently  vary  among EmCare's  hospital clients.
However, the Company believes that its  experience, including its many years  of
case  histories, enables it to  provide assistance in a  broad array of clinical
settings.
 
    The Company provides a computerized quality assurance and improvement system
that a number of  its hospital clients use  to assist physicians in  maintaining
the  consistency and quality of services  to patients. This system, which allows
the ED staff  to review  and evaluate  the type  and quality  of care  provided,
promotes  consistency, objectivity and  confidentiality, while reducing clerical
time spent  generating forms  or  reports. This  quality assurance  software  is
revised and upgraded on a regular basis. This system also facilitates compliance
with  the requirements of accreditation  agencies and management of professional
liability exposure.
 
    ED FACILITY EXPANSION.  In conjunction with its emergency physician practice
management activities,  the  Company seeks  to  generate additional  sources  of
revenue  for its hospital clients by  utilizing the ED's existing facilities and
systems. The Company has worked with several of its hospital clients to  develop
"express  care units" in which  less serious cases can  be treated on a separate
schedule rather  than  competing for  priority  with emergency  cases,  allowing
efficient treatment of additional patients.
 
INFORMATION SYSTEMS
 
    The  Company  has  recently  entered into  a  contractual  agreement  with a
software firm to purchase  software, training, and  maintenance of a  customized
Emergency  Department Information System ("EDIS").  This system will enhance the
Company's existing internal proprietary Clinical Information System  Repository,
and  as  a result,  EmCare will  be  able to  better analyze  physician practice
patterns, develop physician profiles, identify costs and resource utilization by
diagnosis by physician,  and utilize  such information to  assist physicians  in
identifying the most cost efficient patterns of quality practice and provide the
Company  with specific clinical payment and other data to be utilized in managed
care negotiations. The Company  expects to spend  approximately $2.5 million  in
the  rollout of this initiative  to 60 identified client  sites over the next 24
months. See "Use of Proceeds."
 
    The Company  maintains  several  computer  databases to  assist  it  in  its
activities.  For physician recruiting it  has an extensive, proprietary database
of emergency  and  other physicians  which  is maintained  and  updated  through
licensed  databases, personal  contacts, professional  journal advertising, mail
solicitation and  telemarketing. The  Company's other  online databases  contain
hospital,  risk management, payment program, financial and marketing information
that it acquires  on a  daily basis. EmCare  believes that  the availability  of
timely  information is  essential to its  business, particularly  in the rapidly
changing medical market  in the  United States, and  it intends  to continue  to
invest in technology to develop and enhance information systems.
 
OTHER SERVICES
 
    In  addition  to its  emergency physician  practice management,  the Company
provides billing  services, LOCUM  TENENS  (temporary) and  permanent  physician
staffing  services across  a broad range  of medical  specialties, and physician
practice management in areas other than emergency medicine.
 
    BILLING SUBSIDIARY.  In September 1995, the Company acquired RTI, a  billing
company.  As of  January 1,  1996, the Company  began to  perform internally the
billing on some  of its  independent billing  contracts. Previously  third-party
billing  companies were engaged to perform this  function. As of April 30, 1996,
the Company had  transferred to RTI  the billing responsibilities  on 15 of  the
Company's  49 independent billing contracts  previously performed by third-party
billing companies. The Company  expects to complete  this transition during  the
next  twelve months. RTI also performs  billing services for 17 outside clients.
After completing the transition of the  Company's billing contracts to RTI,  the
Company  will seek  to expand  the billing  services that  RTI renders  to third
parties.
 
    PHYSICIAN PLACEMENT SERVICES.  The Company provides LOCUM TENENS (temporary)
and permanent physician staffing services  across a broad range of  specialties,
including emergency medicine, family practice,
 
                                       24
<PAGE>
internal  medicine,  radiology, anesthesia,  obstetrics/gynecology,  surgery and
pathology. Temporary  staffing is  required  by hospitals,  clinics,  individual
physicians,  managed  care plans  and other  health  care organizations  to meet
short-term  staffing  needs   resulting  from   vacations,  continuing   medical
education,  seasonal  shifts  in  patient volume  and  other  factors. Temporary
physician staffing complements  the Company's physician  practice management  by
providing  it  with  the  means,  particularly  during  the  start-up  stage  of
contracts, to meet its own staffing  needs. The Company also provides  permanent
placement  for  a fixed  fee. Physician  placement is  largely conducted  by the
Company  in  Texas,   its  contiguous   states  and   Florida  and   represented
approximately  4% of  the Company's net  revenue during the  twelve months ended
March 31, 1996.
 
    NONEMERGENCY PHYSICIAN PRACTICE MANAGEMENT.  The Company utilizes the skills
it has developed in its ED  activities to support other hospital-based  clinical
specialties,  such as inpatient  intensive care. Similar  to emergency medicine,
such specialties  involve  overall  responsibility for  hospital  patients,  are
essential  to the operation  of the hospital  and require high  quality care and
coordination  with  the  hospital's  medical  staff  and  attending  physicians.
Nonemergency  physician practice management activities represented approximately
3% of the  Company's total  revenues during the  twelve months  ended March  31,
1996.
 
MARKETING
 
    The  Company's  marketing efforts  are  centrally directed  and  involve the
active participation of the Company's executive officers as well as a  marketing
staff  of six  persons at  its Dallas  headquarters. In  marketing its emergency
physician practice management services, the Company targets approximately  2,600
high  volume EDs which provide  24-hour service, have at  least 12,000 ED visits
per year and meet certain other  standards. The Company advertises its  services
in  hospital and health care trade  journals, is represented at various hospital
and  physician   trade  conferences   and   organizes  meetings   for   hospital
administrators and medical staff in order to increase awareness of its services.
These  activities also serve as a means of gathering information about potential
clients and obtaining feedback about hospital needs. Marketing leads  concerning
new hospital clients generally result from referrals by hospital administrators,
information  provided by physicians and requests for proposals received directly
from hospitals.
 
    The Company's proposal  to a  prospective hospital  client is  based on  its
analysis of information received from the hospital, including numbers and acuity
levels  of patients visiting the ED, payor  mix and desired staffing levels, and
on evaluation visits to the prospective  client. The Company evaluates the  ED's
anticipated  patient  volumes,  payor  mix and  payment  program  rates  and the
likelihood of changes in  payment rates applicable to  the hospital. A  proposal
generally  includes an overview  of the hospital's  current staffing program, an
evaluation of the  strengths and weaknesses  of the ED,  an analysis of  current
versus projected revenue and costs following commencement of EmCare's management
services, as well as the economic terms of the proposed program.
 
CONTRACTUAL ARRANGEMENTS
 
    The  Company structures its contractual  arrangements for physician practice
management in one of two ways. In  certain states in order to avoid  uncertainty
as  to the  scope of  laws regulating  the corporate  practice of  medicine, for
regulatory convenience or because the  Company acquired contracts structured  in
that  manner, EmCare's services are provided in conjunction with the PAs. All of
the PAs are currently owned by Dr. Riggs or other physicians affiliated with the
Company. Under  this  arrangement (the  "PA  Structure"),  a PA  enters  into  a
management  agreement with  the hospital  client and  contracts with physicians,
generally on an independent contractor  basis, to provide the necessary  medical
practice  coverage. The nonmedical portion of the service under the PA Structure
is provided by EmCare pursuant to a long-term management agreement with the  PA.
In  other  jurisdictions, a  wholly-owned  subsidiary of  the  Company contracts
directly with both  the hospital  and the physicians  (the "EmCare  Structure").
Under  all structures, all decisions regarding patient care are made exclusively
by the physicians.  See "Risk Factors  -- Dependence on  Key Personnel, PAs  and
Qualified Physicians."
 
    HOSPITAL  RELATIONSHIPS  AND  BILLING  ARRANGEMENTS.   Under  either  the PA
Structure or the EmCare  Structure, the management  agreement with the  hospital
client  grants EmCare  the exclusive right  and responsibility  to contract with
physicians to provide  services at  the hospitals.  These management  agreements
typically  have terms of  one to three  years and are  renewed automatically for
additional one-year terms at the end of
 
                                       25
<PAGE>
each term, subject to termination  by either party by  notice not later than  90
days  prior to the  end of the  then-current term. The  Company's contracts with
certain of its hospital  clients require the Company  to indemnify the  hospital
for  losses  suffered  thereby,  including losses  resulting  from  a contracted
physician's malpractice.
 
    Services performed  by  physicians  under  contract  with  the  Company  are
generally  charged on a fee  for service basis, and  EmCare's revenue is derived
from such fees. These fees are either:  (i) billed and collected by the  related
hospital,  which remits monthly  to EmCare a  negotiated amount ("hospital-based
billing  contracts"),  or  (ii)  billed  and  collected  separately  by   EmCare
("independent  billing  contracts").  Under  independent  billing  contracts the
Company assumes  the  financial  risks  related  to  collection,  including  the
potential  uncollectibility  of  accounts  and delays  attendant  to  payment by
third-parties. At April 30,  1996, approximately 58%  of the Company's  hospital
contracts  provided for independent billing,  compared with approximately 31% at
December 31, 1990.  In independent  billing contract  arrangements, the  Company
previously  arranged for third-party billing firms  to bill and collect directly
for ED services  performed by its  physicians. On January  1, 1996, the  Company
began to transfer that responsibility to its billing subsidiary. As of April 30,
1996,  the Company had completed  the transfer to RTI of  15 of the Company's 49
independent billing contracts  on which it  previously used third-party  billing
companies.  See "-- Other Services" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
    In addition, certain of the  Company's contracts with hospitals provide  for
the payment to EmCare by the hospital of specified amounts to supplement revenue
derived from physician fees.
 
    PHYSICIAN RELATIONSHIPS.  EmCare contracts with or employs its ED physicians
to provide the medical services necessary to fulfill its obligations to hospital
clients under physician practice management contracts. Physicians under contract
with  EmCare  are  compensated  based upon  departmental  performance  and their
individual contribution to  such performance,  subject to  a guaranteed  minimum
fixed  income. Each  physician assigns  to the  Company all  rights to  fees and
payments  for  medical  services.  The  independent  contractor  physicians  are
responsible   for  their  own  self-employment   tax  and  any  other  statutory
deductions. Physicians  are  required  to  hold a  currently  valid  license  to
practice  in the appropriate state and to apply for and be granted medical staff
privileges at the hospital client. Such staff privileges automatically terminate
upon termination of the physician's contract with the Company.
 
    The Company's agreements with physicians  generally have one-year terms  and
are  renewable from year to  year, subject to termination  by either party as of
the end of any term upon notice given not later than 90 days prior to the end of
the then current term.
 
    Hospital clients with  higher volume EDs  of the type  commonly serviced  by
EmCare  generally demand  board certified  emergency physicians.  While there is
currently a shortage of board certified emergency physicians, to date EmCare has
not been  adversely affected  by such  shortage. Such  shortage could  adversely
affect  the Company in the future. See "Risk Factors -- Risks Relating to Growth
Strategy."
 
    Physicians placed by  the Company on  a LOCUM TENENS  basis generally  enter
into  contracts with  the Company  which are  terminable on  30 days'  notice by
either party. The  Company's contracts with  these physicians typically  provide
for the physician to provide temporary services for a minimum number of weeks in
a one-year period. These physicians are compensated on a per day/per hour basis,
with  all relocation expenses paid. Under  its agreement with the client, EmCare
also receives payment on a per day/per hour basis.
 
    PA MANAGEMENT AGREEMENTS.   EmCare  has entered  into management  agreements
("PA  Management Agreements")  with each  of the  PAs. Under  such PA Management
Agreements, the  PAs  delegate  to EmCare  the  administrative,  management  and
support  functions (but not any functions constituting the practice of medicine)
that the PAs have agreed to provide to the hospital client. In consideration  of
such  services, each PA pays to EmCare a  monthly fee which may be adjusted from
time to  time  to reflect  industry  practice, business  conditions  and  actual
expenses  for administrative costs and uncollectible accounts. See "Risk Factors
- -- State Laws Regarding Prohibition of Corporate Practice of Medicine" and "Risk
Factors -- Dependence on Key Personnel, PAs and Qualified Physicians."

                          DESCRIPTION OF CAPITAL STOCK
 
    The authorized capital stock of the Company consists of 25,000,000 shares of
Common Stock, par value $.01 per share, and 5,000,000 shares of Preferred Stock,
par value $.01 per share.
 
COMMON STOCK
 
    As  of May 31, 1996, there were 8,139,840 shares of Common Stock outstanding
and held of record by approximately  83 stockholders. Based upon such number  of
shares  outstanding as  of that date  and giving  effect to the  issuance of the
1,500,000 shares of Common  Stock offered by the  Company hereby, there will  be
9,639,840 shares of Common Stock outstanding upon the closing of this offering.
 
    Holders  of Common Stock are entitled to one vote for each share held and do
not have cumulative  voting rights. Accordingly,  holders of a  majority of  the
shares  of Common Stock entitled to vote  in any election of directors may elect
all of the directors standing for election. Holders of Common Stock are entitled
to receive pro rata such dividends, if any,  as may be declared by the Board  of
Directors  out of funds legally available  therefor, subject to any preferential
dividend  rights  of   outstanding  Preferred  Stock.   Upon  the   liquidation,
dissolution  or  winding up  of the  Company,  the holders  of Common  Stock are
entitled to receive pro rata the net  assets of the Company available after  the
payment of all creditors and liquidation preferences, if any, of any outstanding
Preferred  Stock.  Holders of  Common  Stock have  no  preemptive, subscription,
redemption or conversion rights. The outstanding shares of Common Stock are, and
the shares  offered  hereby  when  issued  and sold  will  be,  fully  paid  and
nonassessable. The rights, preferences and privileges of holders of Common Stock
are  subject to, and may be adversely affected  by, the rights of the holders of
shares of any  series of  Preferred Stock which  the Company  may designate  and
issue in the future.
 
PREFERRED STOCK
 
    The  Board  of  Directors  is  authorized,  subject  to  certain limitations
prescribed by law, without further stockholder  approval, to issue from time  to
time  up to an aggregate  of 5,000,000 shares of Preferred  Stock in one or more
series. Each series of Preferred Stock  shall have such rights and  preferences,
including  dividend rights, conversion rights, voting rights, redemption rights,
(including sinking  fund provisions)  and liquidation  preferences as  shall  be
determined  by the Board of Directors. The  issuance of Preferred Stock may have
the effect  of delaying,  deferring or  preventing a  change of  control of  the
Company  without further action  by the stockholders.  Further, the existence of
unissued and unreserved Preferred Stock could have a depressive effect upon  the
market  price of the Common Stock. The Company has no present plans to issue any
shares of Preferred Stock. There are no shares of Preferred Stock outstanding.
 
DELAWARE LAW AND CERTAIN CHARTER AND BY-LAW PROVISIONS
 
    The Company is  subject to  the provisions of  Section 203  of the  Delaware
General  Corporation Law  ("DGCL"). Subject  to certain  exceptions, Section 203
prohibits a  publicly-held Delaware  corporation from  engaging in  a  "business
combination"  with an "interested stockholder" for a period of three years after
the date of the transaction in which  the person or entity became an  interested
stockholder,  unless the  interested stockholder  attained such  status with the
approval of  the  Board of  Directors  or  unless the  business  combination  is
approved  in  a prescribed  manner. A  "business combination"  includes mergers,
asset sales  and other  transactions resulting  in a  financial benefit  to  the
interested   stockholder.   Subject  to   certain  exceptions,   an  "interested
stockholder" is a person or entity who, together with affiliates and associates,
owns, or within the three years immediately preceding the "business combination"
did own, 15% or more of the corporation's outstanding voting stock.
 
    The amended certificate of incorporation of the Company (the "Charter")  and
the  amended by-laws of the Company (the  "By-laws") provide for the division of
the Board of Directors into  three classes as nearly  equal in size as  possible
with  staggered  three-year terms.  See  "Management --  Executive  Officers and
Directors." Any director may be removed only with cause, by the vote of at least
a majority of  the shares entitled  to vote  for the election  of directors.  In
addition,  subject to certain limitations, the  Board of Directors may from time
to time change the number of directors,  and vacancies in a class may be  filled
only  by a vote of directors of such  class. These provisions could make it more
difficult for stockholders to change the composition of the Board of Directors.
 
                                       31
<PAGE>
    The Company's  By-laws  provide  that  for  nominations  for  the  Board  of
Directors or for other business to be properly brought by a stockholder before a
meeting  of stockholders,  the stockholder must  first have  given timely notice
thereof  in  writing  to  the  Secretary  of  the  Company.  To  be  timely,   a
stockholder's  notice  with  respect  to an  annual  meeting  generally  must be
delivered not less than 120 days nor more than 150 days prior to the anniversary
of the proxy  statement for  the prior year's  annual meeting.  With respect  to
special meetings, notice must generally be delivered not more than 90 days prior
to such meeting and not later than the later of 60 days prior to such meeting or
10  days following the day on which public announcement of such meeting is first
made by  the Company.  The  notice must  contain,  among other  things,  certain
information  about  the stockholder  delivering the  notice and,  as applicable,
background information  about each  nominee  or a  description of  the  proposed
business to be brought before the meeting.
 
    The  foregoing provisions could have the  effect of making it more difficult
for a third-party to acquire, or  of discouraging a third-party from  acquiring,
control of the Company.
 
    The  Charter provides that any  action required or permitted  to be taken by
the stockholders of the  Company may be  taken only at a  duly called annual  or
special meeting of the stockholders and not by written consent, and that special
meetings  may be called  only by the Chairman  of the Board  of Directors or the
President of the Company. These provisions may also discourage another person or
entity from making a tender offer  for the Company's Common Stock, because  such
person  or entity,  even if  it acquired  a majority  of the  outstanding voting
securities of the Company, would be able  to take action as a stockholder  (such
as  electing  new  directors  or  approving a  merger)  only  at  a  duly called
stockholders meeting, and not by written consent.
 
    The Charter contains certain provisions permitted under the DGCL relating to
the liability of  directors. These provisions  eliminate a director's  liability
for  monetary  damages  for  a  breach  of  fiduciary  duty,  except  in certain
circumstances  involving  certain  wrongful  acts,  such  as  the  breach  of  a
director's  duty  of  loyalty or  acts  or omissions  which  involve intentional
misconduct or a knowing violation of  law. The Charter and By-laws also  contain
provisions indemnifying the directors and officers of the Company to the fullest
extent  permitted by the  DGCL. The Company believes  that these provisions will
assist the Company in attracting and retaining qualified individuals to serve as
directors and officers.
 
    The DGCL provides generally that the  affirmative vote of a majority of  the
shares  entitled to  vote on  any matter  is required  to amend  a corporation's
certificate of incorporation or by-laws,  unless a corporation's certificate  of
incorporation or by-laws, as the case may be, requires a greater percentage. The
Charter  requires the  affirmative vote of  the holders  of at least  75% of the
outstanding voting stock of the Company to amend or repeal any of the  foregoing
Charter  provisions or to reduce the number of authorized shares of Common Stock
or Preferred  Stock. Such  75% vote  is also  required to  amend or  repeal  the
By-laws.  The By-laws may also be amended or  repealed by a majority vote of the
Board of  Directors. Such  75% stockholder  vote  would be  in addition  to  any
separate  class vote that might in the  future be required pursuant to the terms
of any Preferred Stock that might be outstanding at the time any such amendments
are submitted to stockholders.
 
    Section 203 of  the DGCL  and the provisions  of the  Company's Charter  and
By-laws described above may make it more difficult for a third-party to acquire,
or  discourage acquisition bids  for, the Company.  These provisions could limit
the price that  certain investors  might be  willing to  pay in  the future  for
shares  of Common Stock and could have a depressive effect upon the market price
of the Common Stock.

    The  transfer  agent  and  registrar  for  the  Common  Stock  is   Chemical

    The  Underwriting  Agreement provides  that the  obligations of  the several
Underwriters to pay for and  accept delivery of the  shares of Common Stock  are
subject  to  certain  conditions. If  any  of  the shares  of  Common  Stock are
purchased by the Underwriters pursuant  to the Underwriting Agreement, all  such
shares  of Common Stock  (other than the  shares of Common  Stock covered by the
over-allotment options described below) must be so purchased.
 
    The  Company  and  the  Selling  Stockholders  have  been  advised  by   the
Representatives  that the  Underwriters propose  to offer  the shares  of Common
Stock directly to the public initially at  the price to the public set forth  on
the  cover page of this  Prospectus and to certain  dealers (who may include the
Underwriters) at such price less a concession not to exceed $    per share.  The
Underwriters  may allow, and such dealers may  reallow, a discount not to exceed
$    per share to any other Underwriter and certain other dealers.
 
    The Company and the  Selling Stockholders have  granted to the  Underwriters
options  to purchase additional shares  of Common Stock of  up to 229,500 shares
and 40,500 shares, respectively, at the  public offering price set forth on  the
cover  page hereof less underwriting discounts  and commissions, solely to cover
over-allotments. Such options may be exercised  at any time until 30 days  after
the  date of this Prospectus. To the  extent that the Underwriters exercise such
options, each  of  the  Underwriters  will  be  committed,  subject  to  certain
conditions,  to  purchase  a  number  of  option  shares  proportionate  to such
Underwriter's initial commitment as indicated in the preceding table.
 
    The Company, the Selling Stockholders and the Company's other directors  and
executive  officers, subject  to certain exceptions,  have agreed  not to offer,
sell or  otherwise  dispose  of  any  shares of  Common  Stock,  or  any  shares
exercisable  for  or  convertible into  shares  of  Common Stock,  prior  to the
expiration of  90 days  from the  date  of this  Prospectus, without  the  prior
written  consent of Donaldson, Lufkin  & Jenrette Securities Corporation, acting
on behalf of the Underwriters.
 
    The Company  and  the Selling  Stockholders  have agreed  to  indemnify  the
Underwriters  against  certain  liabilities,  including  liabilities  under  the
Securities Act or to contribute payments  that the Underwriters may be  required
to make in respect thereof.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
The Board of Directors
EmCare Holdings Inc.
 
We  have audited the accompanying consolidated balance sheets of EmCare Holdings
Inc. as of December 31, 1995  and 1994, and the related consolidated  statements
of  income, stockholders' equity, and cash flows  for each of the three years in
the  period  ended  December  31,  1995.  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  consolidated financial position  of EmCare Holdings
Inc. at  December 31,  1995 and  1994,  and the  consolidated results  of  their
operations  and their cash flows for each of the three years in the period ended
December 31, 1995, in conformity with generally accepted accounting principles.

                              EMCARE HOLDINGS INC.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                DECEMBER 31, 1995 AND MARCH 31, 1996 (UNAUDITED)
 
1.  ORGANIZATION AND BASIS OF PRESENTATION
    EmCare  Holdings  Inc.  ("Holdings,"  together  with  its  subsidiaries  and
affiliates, the "Company") was incorporated on January 9, 1992, for purposes  of
effecting  a recapitalization of EmCare, Inc.  The Company is a leading provider
of physician services management in  hospital emergency departments and  related
urgent  care  centers (collectively  "EDs") in  the  United States.  The Company
recruits and evaluates  the credentials  of physicians,  arranges contracts  for
their services, assists in monitoring their performance and arranges scheduling.
In  addition, the Company assists its clients in such operational areas as staff
coordination, quality  assurance,  departmental accreditation,  billing,  record
keeping,  third  party  reimbursement, and  other  administrative  services. The
Company markets these services primarily to larger hospitals with higher  volume
EDs  (more than 12,000 patient visits per year) and multi-site systems, where it
believes it  is  able  to  attract and  retain  higher  quality  physicians  and
establish  more stable relationships with hospital clients. The Company, through
its predecessors  and  affiliates,  has  been  engaged  in  emergency  physician
services management for more than 20 years. As of December 31, 1995, the Company
had management contracts relating to 75 EDs in 17 states.
 
    Emergency  physician services management is  the Company's principal line of
business. In addition to the Company's emergency physician services  management,
the Company provides physician services management for hospital-based radiology,
intensive  care and lower volume emergency medicine practices, and for a primary
care physician group practice.  The Company also  provides billing services  for
emergency   physician  services  management  contracts  and  provides  physician
placement services,  primarily on  a LOCUM  TENENS (temporary)  basis, across  a
broad range of practice specialties.
 
    In  certain states, because of the "corporate practice of medicine" doctrine
concerns,  the  Company  enters  into  management  agreements  with   affiliated
professional  associations owned by  the Company's Chairman  and Chief Executive
Officer (the "PA Affiliates") which in  turn contract with hospital clients  and
physicians  in these states. In other states the Company contracts directly with
its hospital clients and physicians.
 
    The consolidated financial statements include  the accounts of Holdings  and
its  subsidiaries  and the  PA Affiliates.  The financial  statements of  the PA
Affiliates are consolidated with Holdings and its subsidiaries because  Holdings
has  unilateral control over the assets and operations of the PA Affiliates and,
notwithstanding the lack of technical  majority ownership, consolidation of  the
PA  Affiliates is necessary to present fairly the financial position and results
of operations  of  Holdings because  of  the existence  of  a  parent-subsidiary
relationship  by means other than record  ownership of the PA Affiliates' voting
stock. Control of  the PA  Affiliates by Holdings  is perpetual  and other  than
temporary because the PA Affiliates have agreed with Holdings that they will not
terminate  any  management  agreement  or  other  arrangements  established with
Holdings, without  the  prior  written  consent  of  Holdings.  All  significant
intercompany and interaffiliate accounts and transactions have been eliminated.
 
2.  SIGNIFICANT ACCOUNTING POLICIES
 
    NET REVENUE AND PROFESSIONAL EXPENSES
 
    Revenue is recorded in the period the services are rendered as determined by
the  respective contracts with the  health care providers. Professional expenses
are based  on  the  terms  of the  respective  contracts  with  the  independent
contractor physicians.
 
    Services  performed  by  physicians  under  contract  with  the  Company are
generally charged  on a  fee for  service basis,  and the  Company's revenue  is
derived  from such  fees. These  fees are  either (i)  collected by  the related
hospital, which  remits a  negotiated amount  monthly to  the Company,  or  (ii)
billed and collected

separately  by  the Company  ("independent  billing contracts").  In independent
billing contract  arrangements, the  Company  arranges for  third-party  billing
firms  or a subsidiary  to bill and  collect directly for  services performed by
these physicians. Cost of collections is included in professional expense.
 
    CASH AND CASH EQUIVALENTS
 
    Money  market   investments,   U.S.  government   agency   securities,   and
certificates  of deposit with banks with maturities of three months or less from
date of purchase are considered to be cash equivalents. Money market investments
are in overnight investment funds whose underlying collateral is U.S. government
securities.
 
    MARKETABLE SECURITIES
 
    Investments in marketable securities are stated at cost, which  approximates
market.   These  investments  are  in   U.S.  government  securities  and  other
federally-insured securities. All marketable securities purchased by the Company
are held to maturity. The marketable  securities held at December 31, 1995  will
mature within one year.
 
    ACCOUNTS RECEIVABLE
 
    Accounts  receivable are primarily  amounts due from  hospitals, amounts due
from third-party payors,  such as insurance  companies, self-insured  employers,
and  government-sponsored  health  care programs  (Medicare  and  Medicaid), and
amounts due from patients.
 
    Accounts receivable  due  under  independent billing  contracts  include  an
allowance  for contractual adjustments and  charity and other adjustments, which
is charged to operations based on an evaluation of potential losses. Contractual
adjustments result from the difference between the rates for physician  services
performed  and amounts  allowed by third-party  payors for  such services. Other
adjustments represent services provided to patients that are not expected to  be
collected at the time service is provided.
 
    FURNITURE AND OFFICE EQUIPMENT
 
    Furniture  and office equipment are stated at cost. Depreciation is computed
using the straight-line  method over  estimated useful  lives generally  ranging
from  five to seven years.  Property under capital lease  is amortized using the
straight-line method over the life of the respective lease. Such amortization is
included with depreciation expense in the accompanying financial statements.
 
    PROFESSIONAL LIABILITY INSURANCE
 
    Professional  liability  insurance  expense   has  been  accrued  based   on
management's expectation that it will provide extended reporting period coverage
to  its independent  contractor physicians.  The accruals  are based  on amounts
provided by the Company's professional  liability insurance carriers (Note  11).
Professional liability insurance expense is included in professional expenses.
 
    OTHER ASSETS
 
    The  non-competition agreements, contracts and goodwill are recorded at cost
on the date of the agreement or acquisition. The non-competition agreements  are
being  amortized over the terms of the  agreements, which range from two to five
years. The  amortization is  based on  straight-line or  an accelerated  method,
which management believes systematically recognizes the decline over time in the
value  of  the  non-competition agreement.  The  non-competition  agreements for
certain officers of the  Company were terminated effective  January 15, 1994  in
consideration  of  certain  restrictions (which  lapsed  upon  Holdings' initial
public offering in 1994)  upon the transfer  of stock of  Holdings held by  such
officers.  Amortization expense in 1993 includes  the write-off of the remaining
assets related to the officers' non-competition agreements at December 31, 1993,
of $2,031,000. Contracts  acquired in  business acquisitions are  valued at  the
date of

acquisition  and are  being amortized  on a  straight line  basis over  eight to
twelve years. Goodwill, which represents  the excess purchase price of  acquired
businesses  over the fair value of net  assets acquired, is being amortized on a
straight-line basis over 40 years.
 
    Deferred financing  costs,  which consist  of  costs incurred  in  obtaining
financing,  are amortized using  the effective interest method  over the term of
the related debt, and such amortization is included in interest expense.
 
    LONG-LIVED ASSETS
 
    The Company reviews the  carrying value of a  long-lived asset if facts  and
circumstances  suggest that it  may be impaired or  that the amortization period
may need to be changed. The  Company considers external factors relating to  the
long-lived  asset,  including  hospital and  physician  contract  changes, local
market developments,  changes  in third  party  payments, national  health  care
trends,  and  other publicly  available information.  If these  external factors
indicate the long-lived asset will  not be recoverable, based upon  undiscounted
cash  flows of the long-lived asset over  the remaining life, the carrying value
of the long-lived asset will be reduced by the estimated shortfall of discounted
cash flows. The  Company does not  believe there are  any indicators that  would
require  an adjustment to the  carrying value of its  long-lived assets or their
remaining useful lives as of December 31, 1995.
 
    STOCK-BASED COMPENSATION
 
    The Company has elected  to follow Accounting  Principles Board Opinion  No.
25,   "Accounting  for  Stock  Issued  to  Employees"  ("APB  25")  and  related
interpretations in  accounting for  its employee  stock options.  Under APB  25,
since  the exercise  price of  the Company's  employee stock  options equals the
market price  of the  underlying stock  on the  date of  grant, no  compensation
expense is recognized.
 
    INCOME TAXES
 
    The Company accounts for income taxes using the liability method as required
by  FASB Statement No.  109, "Accounting for Income  Taxes." Under the liability
method, deferred tax assets and liabilities are determined based on  differences
between  financial reporting  and tax  bases of  assets and  liabilities and are
measured using the enacted tax  rates and laws that will  be in effect when  the
differences are expected to reverse.
 
    INTERIM FINANCIAL DATA (UNAUDITED)
 
    The unaudited consolidated balance sheet as of March 31, 1996, the unaudited
consolidated  statements of  income and  cash flows  for the  three months ended
March  31,  1995  and  1996,   and  the  unaudited  consolidated  statement   of
stockholders'  equity for the three months ended  March 31, 1996 include, in the
opinion  of  management,  all   adjustments  (consisting  of  normal   recurring
adjustments)  necessary to  present fairly the  Company's consolidated financial
position, results of  operations and  cash flows.  The data  disclosed in  these
notes  to the consolidated financial statements  for these periods is unaudited.
Operating results  for the  three month  period  ended March  31, 1996  are  not
necessarily  indicative of the results that may  be expected for the year ending
December 31, 1996.
 
    NET INCOME (LOSS) PER SHARE
 
    Net income (loss) per share is  calculated by dividing net income (loss)  by
the  weighted average number of common  and common equivalent shares outstanding
during the period. Common  equivalent shares consist of  the dilutive effect  of
outstanding  options calculated using the  treasury stock method and mandatorily
redeemable convertible preferred stock.

2.  SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    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 amounts  reported in the  financial statements  and
accompanying notes. Actual results could differ from those estimates.
 
    RECLASSIFICATIONS
 
    Certain prior period amounts have been reclassified to conform with the 1995
presentation.
 
3.  ACCOUNTS RECEIVABLE AND NET REVENUE
    Accounts  receivable are recorded at net realizable value. The allowance for
contractual adjustments and charity and other adjustments is based on historical
experience and future expectations. Accounts receivable consist of the following

    During 1995, the Company had a revolving  line of credit with a bank for  up
to  $20 million  for working capital  and acquisition purposes.  On February 20,
1996, the Company entered into a revolving line of credit (the "Revolver")  with
a bank acting as administrative agent for a syndicate of lenders under which the
Company  can  borrow  up to  $50  million  for working  capital  and acquisition
purposes. The  Revolver  matures on  February  20, 1999.  Borrowings  under  the
Revolver  bear interest at variable rates based, at the Company's option, on the
bank's base rate or the Eurodollar rate. A per annum commitment fee varying from
 .1875% to .375% depending upon the  Company's ratio of funded debt to  operating
cash flow is required on the unused portion of the commitment.

5.  SHORT-TERM DEBT AND LONG-TERM OBLIGATIONS (CONTINUED)
    The  Revolver  contains covenants  which,  among other  things,  require the
Company to maintain certain financial  ratios and impose certain limitations  or
prohibitions  on  the  Company  with  respect  to  the  incurrence,  guaranty or
assumption  of  indebtedness,  the  payment  of  dividends,  the  redemption  or
repurchase  of, or other  payment with respect to,  the Company's capital stock,
certain  cash  transactions  with  subsidiaries  and  affiliates,  acquisitions,
contract management maintenance, and ownership of the PA Affiliates.
 
    During  December 1994,  the Company utilized  $14.5 million  of the proceeds
from the sale of Common  Stock to retire the subordinated  debt. As a result  of
the  early  retirement  of  the  subordinated  debt,  the  Company  incurred  an
extraordinary charge of approximately $837,000, net of taxes. The  extraordinary
charge,  before taxes, is  comprised of approximately  $1,022,000 of unamortized
original issue discount and $286,000 of unamortized loan origination fees.
 
    As of December  31, 1995, the  maturities of short-term  and long-term  debt
were as follows (in thousands):

    Interest  payments were $871,000, $2,317,000 and $289,000 in 1993, 1994, and
1995, respectively, and $177,000  and $69,000 for the  three months ended  March

stockholders  and officers in  1993 and 1994  totaled $1,933,000 and $1,672,000,
respectively.  The  weighted  average  interest  rate  is  6.84%  and  8.07%  on
short-term borrowings outstanding at December 31, 1994 and 1995, respectively.
 
6.  BENEFIT PLANS
    In  1994, the Company instituted a  qualified contributory savings plan and,
in connection with a 1995 acquisition, adopted the plan previously sponsored  by
the  acquired company.  These plans  are qualified  under Section  401(k) of the
Internal Revenue Code (collectively, the  "401(k) Plans"). The 401(k) Plans  are
open  to substantially all  full-time employees of the  Company or any affiliate
who have  completed  one year  of  eligible service  with  the Company  or  such
affiliate.  The  401(k) Plans  permit  participant contributions  and  require a
contribution from the Company  based on the  participant's contribution and  the
subsidiary  or affiliate  that employs  the participant.  The 401(k)  Plans also
allow the Company  to make other  discretionary contributions, including  profit
sharing  contributions.  The Company  contributed $222,000  and $325,000  to the
401(k) Plans in 1994 and 1995, respectively.
 
    The Company's  matching  contributions on  behalf  of an  eligible  employee
generally  become fully vested  if such employee  reaches normal retirement age,
dies or becomes disabled while an employee, or completes five years of  service.
Prior  to an eligible  employee completing five years  of service, such employee
will partially vest at 40%, 60% and  80%, at the end of such employee's  second,
third, and fourth years of service, respectively.

6.  BENEFIT PLANS (CONTINUED)
    The  Company  merged  its  subsidiary's  Money  Purchase  Pension  Plan (the
"Pension Plan") with  the 401(k) Plan  instituted in 1994.  The Pension Plan  (a
defined contribution plan) was open to all full-time employees of the Company or
any affiliate who were 21 or more years of age and who had completed one or more
years of service with the Company. The Company contributed an amount equal to 6%
of  each  eligible  employee's annual  compensation  up to  the  Social Security
taxable wage base, plus 11.7% on compensation in excess of this wage base, up to
a maximum  compensation  level allowed  by  the Internal  Revenue  Service.  The
Company  contributed $357,000 and $99,000 in 1993 and 1994, respectively, to the
Pension Plan.

8.  STOCK OPTIONS (CONTINUED)
    The Company issued options for 50,000 shares at $14.00 per share on December
31, 1992, which were exercised in February 1993. Stock options for 32,000 shares
of common stock  at $14.00 per  share were  also granted in  connection with  an
acquisition in 1993 and were subsequently exercised in 1995.
 
    The  exercise of stock options in 1995 resulted in a tax benefit of $733,000
which was accounted for as paid-in capital.
 
9.  STOCKHOLDERS' EQUITY
    In December 1994, the Company issued 2,587,500 shares of its common stock at
$11.00 per share in an initial  public common stock offering. Proceeds from  the
offering,  net of  commissions and  other related  expenses totaling $3,185,000,
were $25,278,000, of which $14,500,000 was  used to repay subordinated debt.  In
connection  with the offering, the  mandatorily redeemable convertible preferred
stock was converted into 2,939,976 shares of common stock.
 
10. LEASES
    The Company leases office space for primary terms of one to ten years,  with
options  to renew for  additional periods. Future minimum  payments due on these
operating leases are as follows at December 31, 1995 (in thousands):

    Rent expense under operating leases for  1993, 1994, and 1995 was  $597,000,
$662,000 and $762,000, respectively.
 
    The  Company entered into an operating lease, which will commence during the
second quarter of 1996, for office space for its billing operations pursuant  to
a seven and one-half year lease agreement expiring in 2002. The commitment under
the lease will range from approximately $500,000 to $1.2 million per year.
 
11. PROFESSIONAL LIABILITY INSURANCE
    The  Company  requires the  independent contractor  physicians with  whom it
contracts  to  obtain  professional  liability  insurance  coverage  and   makes
available  to the physicians such insurance. Prior  to June 1, 1989, the Company
procured  professional  liability  insurance  for  the  independent   contractor
physicians  on a  claims-made basis and,  effective May 31,  1989, exercised its
option for  seven-year extended  reporting period  coverage. Beginning  June  1,
1989,  the Company again procured  insurance coverage for professional liability
claims on a claims-made basis. The current policy expires on December 31,  1997.
Although  the  majority of  the professional  liability insurance  available for
independent contractor physicians is procured in this manner, in certain  cases,
these  physicians may obtain their own professional liability insurance directly
or through the contracting hospital.

12. FAIR VALUES OF FINANCIAL INSTRUMENTS
    The carrying amounts of the Company's financial instruments at December  31,
1995  approximate fair value. The following methods and assumptions were used by
the Company in estimating its fair value disclosures for financial instruments:
 
<TABLE>
<S>                             <C>
CASH AND CASH EQUIVALENTS:      The carrying  amount  reported  in  the  balance
                                sheet for cash and cash equivalents approximates
                                its fair value.
MARKETABLE SECURITIES:          The  fair values  for marketable  securities are
                                based on quoted market prices.
LONG AND SHORT-TERM DEBT:       The fair values of the Company's long-term  debt
                                are   estimated   using  discounted   cash  flow
                                analyses, based on the Company's current  incre-
                                mental  borrowing  rates  for  similar  types of
                                borrowing arrangements.

13. ACQUISITIONS
    On February 18, 1994,  the Company acquired  a business providing  emergency
department  services  for  hospitals  in Texas  for  aggregate  consideration of
$6,376,000, including  an obligation  of $2,326,000  payable over  three  years.
Additionally,  certain sellers entered  into covenants not  to compete valued at

P.A.  ("CEA"),  a physician  practice management  company providing  services to
seven hospital emergency  departments in Maryland,  Virginia, and  Pennsylvania.
CEA  was acquired for aggregate consideration of $15.5 million which consists of
$5,200,000 in  cash, 433,333  shares of  the Company's  common stock  valued  at
$16.88  per share, or an aggregate  of $7,312,494, and obligations of $2,941,000

continue  to work  as employees of  a subsidiary  of the Company.  In the merger
agreement, these individuals also have agreed not to compete against the Company
for the three years immediately after the  merger, subject to a decrease to  two
years  under certain circumstances. The Company allocated $680,000 of the merger
consideration paid upon  consummation of the  merger to these  covenants not  to
compete.

department services for a  hospital in Arkansas  for aggregate consideration  of
$1,500,000,  including an obligation of $300,000 payable over two to seven years
based on certain future contract performance criteria. Additionally, the sellers
entered into covenants not to compete valued at $150,000 in the aggregate.

Reimbursement  Technologies, Inc. ("RTI"), an emergency medicine billing company
in Pennsylvania. RTI provides billing services to emergency physician groups who
supply professional services to  18 high volume  emergency departments in  eight
states.  RTI was purchased for  aggregate consideration of $9,722,000, including
an obligation of $400,000 payable within the next year. Additionally, the former
stockholder of  RTI and  certain key  employees entered  into covenants  not  to
compete valued at $485,000 in the aggregate.
 
    All  the  acquisitions have  been accounted  for as  purchases, and  the net
assets and  operations  are included  in  the Company's  consolidated  financial
statements as of the date of acquisition.

14. CONTINGENCIES
    In June 1995, the Company was informed  that the Civil Division of the  U.S.
Department  of  Justice ("DOJ")  intended to  pursue a  civil lawsuit  against a
vendor which provides billing services on a contract basis for the Company and a
number of  other customers.  The  DOJ alleges  improper  coding by  the  billing
company  of charges for programs (Medicare,  Medicaid, and CHAMPUS) in violation
of the False  Claims Act. Initially,  DOJ agreed not  to name the  Company as  a
defendant  in the lawsuit, but  later informed the Company  that DOJ intended to
pursue the lawsuit against the Company,  as well as other defendants, unless  by
February  1, 1996, settlement  discussions were successful.  The lawsuit was not
settled by the February 1, 1996 deadline and the Company has now been served  in
the lawsuit. Under the Company's contracts with the billing company, the billing
company  has agreed to be responsible for all coding errors. The billing company
has advised the Company it is  confident the DOJ allegations are incorrect.  The
Company  does  not currently  possess  sufficient information  to  determine the
likelihood or amount of potential liabilities, if any.
 
    In addition to its allegations of improper coding, the DOJ has notified  the
Company  of  its position  that  the Company's  contracts  with the  third party
billing company fail to comply with applicable law because the billing company's
fee is  based on  a percentage  of the  amount collected.  The DOJ  has  further
notified  the Company that  the DOJ believes  that, as a  result of such alleged
illegality, each claim submitted for payment under this arrangement  constitutes
a  false  claim under  the  False Claims  Act.  The Company  believes  that such
reassignment is consistent with industry practice. Although the Company is aware
that such reassignments are  not in compliance with  applicable law relating  to
reassignment  of Medicare claims, the Company  does not believe that the failure
to comply with applicable law imposing restrictions on reassignment of  Medicare
claims renders such claims or Medicaid or CHAMPUS claims false claims within the
meaning  of the False Claims Act. If the Company does not prevail on this issue,
it is possible that the DOJ could make similar allegations with respect to:  (i)
reassignments to the third-party billing company after the period covered by the
DOJ  Lawsuit,  and  (ii)  reassignments to  the  Company's  wholly-owned billing
subsidiary.
 
    The Company is also a defendant  in various other legal proceedings  arising
in the ordinary course of business. Although the results of litigation cannot be
predicted  with certainty, management  believes that the  outcome of the pending
other litigation  will not  have  a material  adverse  effect on  the  Company's
consolidated financial statements.
 
15. RELATED PARTY TRANSACTIONS
    In  connection with servicing its independent billing contracts, the Company
enters  into  arrangements  with  companies  that  provide  accounts  receivable
management services. A director of the Company is a

director  of a  company that provides  such services to  the Company. Management
service fees paid by  the Company to  this company in 1993,  1994 and 1995  were
$923,000,  $1,102,000 and  $1,140,000, respectively.  The Company  believes that
this arrangement has been on terms no  less favorable to the Company than  could
have been obtained from an unaffiliated third party.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
DELAWARE GENERAL CORPORATION LAW
 
    Section  145(a) of the General Corporation Law of the State of Delaware (the
"DGCL") provides that a  corporation may indemnify  any person who  was or is  a
party  or  is  threatened to  be  made a  party  to any  threatened,  pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action  by or in the  right of the corporation)  by
reason  of the fact that he is or  was a director, officer, employee or agent of
the corporation, or is  or was serving  at the request of  the corporation as  a
director,  officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against expenses (including attorney's fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by him in connection with  such action, suit or proceeding  if he acted in  good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests  of  the corporation,  and,  with respect  to  any criminal  action or
proceeding, had no reasonable cause to believe his conduct was unlawful.
 
    Section 145(b) of  the DGCL provides  that a corporation  may indemnify  any
person  who  was or  is a  party or  is  threatened to  be made  a party  to any
threatened, pending  or completed  action or  suit by  or in  the right  of  the
corporation  to procure a judgment in its favor by reason of the fact that he is
or was a director, officer, employee or  agent of the corporation, or is or  was
serving  at the request of  the corporation as a  director, officer, employee or
agent of  another  corporation,  partnership,  joint  venture,  trust  or  other
enterprise  against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection with the  defense or settlement of such action  or
suit  if he acted in good faith and in  a manner he reasonably believed to be in
or not opposed  to the  best interests  of the  corporation and  except that  no
indemnification  shall be made  in respect of  any claim, issue  or matter as to
which such  person shall  have been  adjudged to  be liable  to the  corporation
unless  and only to the extent that the  Court of Chancery or the court in which
such action or suit was brought  shall determine upon application that,  despite
the  adjudication of liability but in view of all the circumstances of the case,
such person is  fairly and reasonably  entitled to indemnity  for such  expenses
which the Court of Chancery or such other court shall deem proper.
 
    Section  145(c) of the  DGCL provides that,  to the extent  that a director,
officer, employee or agent of a corporation has been successful on the merits or
otherwise  in  defense  of  any  action,  suit  or  proceeding  referred  to  in
subsections  (a) and (b)  of Section 145, or  in defense of  any claim, issue or
matter therein, he shall be  indemnified against expenses (including  attorneys'
fees) actually and reasonably incurred by him in connection therewith.
 
                                      II-1
<PAGE>
    Section   145(d)  of  the  DGCL  provides  that  any  indemnification  under
subsections (a) and (b) of Section 145 (unless ordered by a court) shall be made
by the corporation only as authorized in the specific case upon a  determination
that  indemnification of the  director, officer, employee or  agent is proper in
the circumstances because  he has  met the  applicable standard  of conduct  set
forth  in subsections (a)  and (b) of  Section 145. Such  determination shall be
made: (i) by the board of directors by a majority vote of a quorum consisting of
directors who were not parties  to such action, suit  or proceeding, or (ii)  if
such  a  quorum  is not  obtainable,  or, even  if  obtainable, if  a  quorum of
disinterested directors so directs,  by independent legal  counsel in a  written
opinion, or (iii) by the stockholders.
 
    Section  145(e)  of the  DGCL provides  that expenses  (including attorneys'
fees) incurred  by an  officer or  director in  defending any  civil,  criminal,
administrative  or investigative action,  suit or proceeding may  be paid by the
corporation in  advance  of  the  final disposition  of  such  action,  suit  or
proceeding  upon receipt of an  undertaking by or on  behalf of such director or
officer to repay such amount if it shall ultimately be determined that he is not
entitled to be indemnified by the corporation as authorized in Section 145. Such
expenses (including attorneys' fees) incurred by other employees and agents  may
be  so paid upon  such terms and conditions,  if any, as  the board of directors
deems appropriate.
 
CERTIFICATE OF INCORPORATION
 
    The Amended  and  Restated  Certificate of  Incorporation  of  the  Company,
provides  that  no person  shall  be personally  liable  to the  Company  or its
stockholders for monetary damages  for breach of fiduciary  duty as a  director,
except  for liability: (i) for  any breach of the  director's duty of loyalty to
the Company or its stockholders, (ii) for acts or omissions not in good faith or
which involve intentional  misconduct or a  knowing violation of  law, (iii)  in
respect  of certain unlawful dividend payments or stock purchases or redemptions
or (iv) for any transaction from which the director derived an improper personal
benefit. If  the  DGCL  is  amended to  authorize  the  further  elimination  or
limitation  of the liability of  directors, then the liability  of a director of
the Company, in addition to the limitation on personal liability provided in the
Amended and  Restated  Certificate of  Incorporation,  will be  limited  to  the
fullest  extent  permitted  by the  DGCL,  as  amended. Further,  any  repeal or
modification of  such  provision of  the  Amended and  Restated  Certificate  of
Incorporation  by the stockholders of the  Company will be prospective only, and
will not adversely affect any limitation on the personal liability of a director
of the Company arising from  an act or omission occurring  prior to the time  of
such repeal or modification.
 
AMENDED AND RESTATED BYLAWS
 
    The Amended and Restated Bylaws of the Company, provide that each person who
at any time is or was a director or officer of the Company, and is threatened to
be  or is made a  party to any threatened, pending  or completed action, suit or
proceeding,   whether   civil,   criminal,   administrative,   arbitrative    or
investigative (a "Proceeding"), by reason of the fact that such person is or was
a director or officer of the Company, or is or was serving at the request of the
Company  as a  director or  officer of  another corporation,  partnership, joint
venture, employee  benefit plan  or other  enterprise, whether  the basis  of  a
Proceeding  is alleged action  in such person's official  capacity or in another
capacity while holding such office, shall  be indemnified by the Company to  the
fullest  extent authorized by the  DGCL or any other  applicable law as may from
time to time be in effect (but, in the case of any such amendment or  enactment,
only to the extent that such amendment or statute permits the Company to provide
broader  indemnification  rights  than  such  law  prior  to  such  amendment or
enactment permitted the  Company to  provide), against  all expense,  judgments,
fines  and amount  paid in settlement  (including attorneys'  fees) actually and
reasonably incurred or suffered by such person in connection with a  Proceeding,
so  long as a majority of a  quorum of disinterested directors, the stockholders
or legal counsel through a written opinion determines that such person acted  in
good faith and in a manner he reasonably believed to be in or not opposed to the
best  interests  of the  Company. Such  indemnification shall  continue as  to a
person who has  ceased to serve  in the capacity  which initially entitled  such
person  to indemnity  thereunder and shall  inure to  the benefit of  his or her
heirs, executors  and  administrators.  The Amended  and  Restated  Bylaws  also
contain  certain provisions designed  to facilitate receipt  of such benefits by
any such persons, including the prepayment of any such benefits.

proceeding involving them by reason of their having been a director, officer, or
other  representative of the Company. The Company must also advance funds to Dr.
Riggs and Mr.  Miller to  cover their reasonable  counsel fees  and other  costs
associated  with their defense of any  such proceeding, provided that they agree
to  repay  any  amounts  advanced  if  they  are  not  ultimately  entitled   to
indemnification by the Company.
 
INSURANCE

to insure its directors and officers against losses resulting from wrongful acts
committed by them in their capacities as directors and officers of the  Company,

ITEM 17.  UNDERTAKINGS.
 
FILINGS INCORPORATING SUBSEQUENT EXCHANGE ACT DOCUMENTS BY REFERENCE
 
    The   undersigned  registrant  hereby  undertakes   that,  for  purposes  of
determining any liability under the Securities  Act of 1933, each filing of  the
registrant's  annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act  of 1934  that is  incorporated by  reference in  the  registration
statement  shall be deemed  to be a  new registration statement  relating to the
securities offered therein,  and the offering  of such securities  at that  time
shall be deemed to be the initial bona fide offering thereof.
 
INCORPORATED ANNUAL AND QUARTERLY REPORTS
 
    The  undersigned  registrant hereby  undertakes to  deliver  or cause  to be
delivered with the prospectus, to each person to whom the prospectus is sent  or
given,  the latest  annual report, to  security holders that  is incorporated by
reference  in  the  prospectus  and  furnished  pursuant  to  and  meeting   the
requirements  of Rule 14a-3 or  Rule 14c-3 under the  Securities Exchange Act of
1934; and,  where interim  financial  information required  to be  presented  by
Article  3 of Regulation S-X is not set  forth in the prospectus, to deliver, or
cause to be delivered to  each person to whom the  prospectus is sent or  given,
the  latest quarterly report  that is specifically  incorporated by reference in
the prospectus to provide such interim financial information.
 
REQUEST FOR ACCELERATION OF EFFECTIVE DATE
 
    Insofar as indemnification for liabilities arising under the Securities  Act
of  1933 may be permitted to directors, officers, and controlling persons of the
registrant pursuant to provisions described in Item 15 above, or otherwise,  the
registrant  has been advised that in the  opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for  indemnification
against  such liabilities (other than the  payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the  registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled  by controlling  precedent, submit  to a  court of  appropriate
jurisdiction  the question whether such indemnification  by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
 
REGISTRATION STATEMENT PERMITTED BY RULE 430A
 
    The undersigned  registrant  hereby undertakes  that:  (i) for  purposes  of
determining  any liability  under the  Securities Act  of 1933,  the information
omitted from the form of prospectus filed as part of this registration statement
in reliance upon Rule 430A  and contained in a form  of prospectus filed by  the
registrant  pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act
shall be deemed to be part of this registration statement as of the time it  was
declared  effective, and (ii) for the purpose of determining any liability under
the Securities Act of 1993, each  post-effective amendment that contains a  form
of prospectus shall be deemed to be a new registration statement relating to the
securities  offered therein,  and the offering  of such securities  at that time
shall be deemed to be the initial bona fide offering thereof.
