BANC OF AMERICA SECURITIES LLC
J.P. MORGAN SECURITIES INC.
     As Initial Purchasers
c/o Banc of America Securities LLC

Ladies and Gentlemen:

            Introductory. AMR HoldCo, Inc., a Delaware corporation ("AMR
HoldCo"), and EmCare HoldCo, Inc., a Delaware corporation ("EmCare HoldCo" and,
collectively with AMR HoldCo, the "Issuers"), propose to issue and sell to the
several Initial Purchasers named in Schedule A (the "Initial Purchasers"),
acting severally and not jointly, the respective amounts set forth in such
Schedule A of $250,000,000 aggregate principal amount of the Issuers' 10% Senior
Subordinated Notes due 2015 (the "Notes"). Banc of America Securities LLC and
J.P. Morgan Securities Inc. have agreed to act as representatives of the several
Initial Purchasers in connection with the offering and sale of the Notes.

            The Notes will be issued pursuant to an indenture, dated as of the
Closing Date (as defined in Section 2 hereof) (the "Indenture"), among the
Issuers, the Guarantors (as defined below) and U.S. Bank Trust National
Association, as trustee (the "Trustee"). Notes will be issued only in book-entry
form in the name of Cede & Co., as nominee of The Depository Trust Company (the
"Depositary"), pursuant to a letter of representations, to be dated on or before
the Closing Date (the "DTC Agreement"), among the Issuers, the Guarantors, the
Trustee and the Depositary.

            The holders of the Notes will be entitled to the benefits of a
registration rights agreement, dated as of the Closing Date (the "Registration
Rights Agreement"), among the Issuers, the Guarantors and the Initial
Purchasers, pursuant to which the Issuers and the Guarantors will agree to file
with the Securities and Exchange Commission (the "Commission"), under the
circumstances set forth therein, (i) a registration statement under the
Securities Act of 1933 (as amended, the "Securities Act," which term, as used
herein, includes the rules and regulations of the Commission promulgated
thereunder) relating to another series of debt securities of the Issuers with
terms substantially identical to the Notes (the "Exchange Notes") to be offered
in ex-



change for the Notes (the "Exchange Offer") and (ii) to the extent required by
the Registration Rights Agreement, a shelf registration statement pursuant to
Rule 415 of the Securities Act relating to the resale by certain holders of the
Notes, and in each case, to use their commercially reasonable efforts to cause
such registration statements to be declared effective.

            The payment of principal of, premium and Liquidated Damages (as
defined in the Indenture), if any, and interest on the Notes and the Exchange
Notes will initially be fully and unconditionally guaranteed on a senior
subordinated basis, jointly and severally, by Emergency Medical Services L.P.,
the direct parent corporation of the Issuers (the "Parent"), and each domestic
subsidiary of an Issuer as of the Closing Date, and, in each case their
respective successors and assigns (together with the Parent, the "Guarantors"),
in each case pursuant to their guarantees (the "Guarantees"); provided, that,
with respect to any representation or warranty made, and any covenant,
obligation or agreement to be performed, shall be made by, and shall be
effective with respect to, a Guarantor (other than Parent) only concurrently
with the Closing Date and the execution and delivery by such Guarantor of a
Joinder Agreement (as defined below) substantially in the form of Exhibit D
hereto. The Notes and the Guarantees attached thereto are herein collectively
referred to as the "Securities"; and the Exchange Notes and the Guarantees
attached thereto are herein collectively referred to as the "Exchange
Securities."

            The proceeds of the Notes, together with an equity contribution of
$219.0 million and initial borrowings of approximately $355.0 million under the
new $450.0 million senior secured credit facility (the "Senior Secured Credit
Facility" and together with all other agreements related to such facility, the
"Credit Documents") will be used to fund the purchase of American Medical
Response, Inc. ("AMR") and EmCare Holdings Inc. ("EmCare" and together with AMR,
the "Targets"), and pay related fees and expenses (collectively, the
"Transactions").

            The Issuers understand that the Initial Purchasers propose to make
an offering of the Securities on the terms and in the manner set forth herein
and in the Offering Memorandum (as defined below) and agree that the Initial
Purchasers may resell, subject to the conditions set forth herein, all or a
portion of the Securities to purchasers (the "Subsequent Purchasers") at any
time after the date of this Agreement. The Securities are to be offered and sold
to or through the Initial Purchasers without being registered with the
Commission under the Securities Act, in reliance upon exemptions therefrom.
Pursuant to the terms of the Securities and the Indenture, investors who acquire
Securities shall be deemed to have agreed that Securities may only be resold or
otherwise transferred, after the date hereof, if such Securities are registered
for sale under the Securities Act or if an exemption from the registration
requirements of the Securities Act is available (including the exemptions
afforded by Rule 144A under the Securities Act ("Rule 144A") or Regulation S
under the Securities Act ("Regulation S")).

            The Issuers have prepared and delivered to each Initial Purchaser
copies of a Preliminary Offering Memorandum, dated January 17, 2005 (the
"Preliminary Offering Memorandum"), and have prepared and will deliver to each
Initial Purchaser copies of the Offering Memorandum, dated January 27, 2005,
describing the terms of the Securities, each for use by such Initial Purchaser
in connection with its solicitation of offers to purchase the Securities. As
used herein, the "Offering Memorandum" shall mean, with respect to any date or
time referred to in this Agreement, the Issuers' Offering Memorandum, dated
January 27, 2005, including

                                      -2-



amendments or supplements thereto, the Canadian supplement thereto and any
exhibits thereto, in the most recent form that has been prepared by the Issuers
and delivered to the Initial Purchasers in connection with their solicitation of
offers to purchase Securities.

            Effective concurrently with the closing of the Transactions, each
Guarantor (other than the Parent) shall execute a joinder agreement (the
"Joinder Agreement"), substantially in the form of Exhibit D hereto, pursuant to
which each such entity will become a party to this Agreement effective as of the
Closing Date.

            All references in this Agreement to financial statements and other
information which is "contained," "included" or "stated" in the Offering
Memorandum (or other references of like import) shall be deemed to mean and
include all such financial statements in the Offering Memorandum.

            The Issuers hereby confirm their agreements with the Initial
Purchasers as follows:

            Section 1. Representations and Warranties. Each of the Issuers and
the Guarantors, jointly and severally, hereby represents, warrants and covenants
to each Initial Purchaser as follows:

            (a) No Registration Required. Subject to compliance by the Initial
Purchasers with the representations and warranties set forth in Section 2(e)
hereof and with the procedures set forth in Section 7 hereof, it is not
necessary in connection with the offer, sale and delivery of the Securities to
the Initial Purchasers and to each Subsequent Purchaser in the manner
contemplated by this Agreement and the Offering Memorandum to register the
Securities under the Securities Act or, until such time as the Exchange
Securities are issued pursuant to an effective registration statement, to
qualify the Indenture under the Trust Indenture Act of 1939 (the "Trust
Indenture Act," which term, as used herein, includes the rules and regulations
of the Commission promulgated thereunder).

            (b) No Integration of Offerings or General Solicitation. None of the
Issuers, their respective affiliates (as such term is defined in Rule 501 under
the Securities Act) (each, an "Affiliate") or any person acting on its or any of
their behalf (other than the Initial Purchasers, as to whom the Issuers make no
representation or warranty) has, directly or indirectly, solicited any offer to
buy or offered to sell, and will not, directly or indirectly, solicit any offer
to buy or offer to sell, in the United States or to any United States citizen or
resident, any security which is or would be integrated with the sale of the
Securities in a manner that would require the Securities to be registered under
the Securities Act. None of the Issuers, their respective Affiliates or any
person acting on its or any of their behalf (other than the Initial Purchasers,
as to whom the Issuers make no representation, warranty or covenant) has engaged
or will engage, in connection with the offering of the Securities, in any form
of general solicitation or general advertising within the meaning of Rule 502
under the Securities Act. With respect to those Securities sold in reliance upon
Regulation S, (i) none of the Issuers, their respective Affiliates or any person
acting on its or their behalf (other than the Initial Purchasers, as to whom the
Issuers make no representation, warranty or covenant) has engaged or will engage
in any directed selling efforts within the

                                      -3-



meaning of Regulation S and (ii) each of the Issuers and their respective
Affiliates and any person acting on its or their behalf (other than the Initial
Purchasers, as to whom the Issuers make no representation, warranty or covenant)
has complied and will comply with the offering restrictions set forth in
Regulation S.

            (c) Eligibility for Resale Under Rule 144A. The Securities are
eligible for resale pursuant to Rule 144A and will not be, at the Closing Date,
of the same class as securities listed on a national securities exchange
registered under Section 6 of the Securities Exchange Act of 1934 (as amended,
the "Exchange Act," which term, as used herein, includes the rules and
regulations of the Commission promulgated thereunder) or quoted in a U.S.
automated interdealer quotation system.

            (d) The Offering Memorandum. The Offering Memorandum does not, and
at the Closing Date will not, include an untrue statement of a material fact or
omit to state a material fact necessary in order to make the statements therein,
in the light of the circumstances under which they were made, not misleading;
provided that this representation, warranty and agreement shall not apply to
statements in or omissions from the Offering Memorandum made in reliance upon
and in conformity with information furnished to the Issuers in writing by any
Initial Purchaser expressly for use in the Offering Memorandum. Each of the
Preliminary Offering Memorandum and the Offering Memorandum, as of its date,
contains all the information specified in, and meeting the requirements of, Rule
144A. Neither of the Issuers nor any Guarantor has distributed and none of them
will distribute, prior to the later of the Closing Date and the completion of
the Initial Purchasers' distribution of the Securities, any offering material in
connection with the offering and sale of the Securities other than a Preliminary
Offering Memorandum or the Offering Memorandum.

            (e) The Purchase Agreement and the Joinder Agreement. This Agreement
has been duly authorized, executed and delivered by, and is a valid and binding
agreement of, the Issuers and the Guarantors, enforceable in accordance with its
terms, except as rights to indemnification and contribution hereunder may be
limited by applicable law or as against public policy and except as the
enforcement hereof may be limited by bankruptcy, insolvency, fraudulent
conveyance, reorganization, moratorium or other similar laws relating to or
affecting the rights and remedies of creditors or by general equitable
principles (whether considered in a proceeding at law or in equity). At the
Closing Date, the Joinder Agreement will have been duly authorized, executed and
delivered by, and will be a valid and binding agreement of, the Guarantors
(other than the Parent), enforceable in accordance with its terms, except as
rights to indemnification and contribution hereunder may be limited by
applicable law or as against public policy and except as the enforcement thereof
may be limited by bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium or other similar laws relating to or affecting the rights and
remedies of creditors or by general equitable principles (whether considered in
a proceeding at law or in equity).

            (f) The Registration Rights Agreement and DTC Agreement. At the
Closing Date, each of the Registration Rights Agreement and the DTC Agreement
will have been duly authorized, executed and delivered by, and will be a valid
and binding agreement of, the Issuers (and, in the case of the Registration
Rights Agreement, the Guarantors), enforceable in accor-

                                      -4-



dance with its terms, except as the enforcement thereof and rights thereunder
may be limited by bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium or other similar laws relating to or affecting the rights and
remedies of creditors or by general equitable principles (whether considered in
a proceeding at law or in equity) and except as rights to indemnification under
the Registration Rights Agreement may be limited by applicable law or as against
public policy.

            (g) Authorization of the Securities and the Exchange Securities. The
Notes to be purchased by the Initial Purchasers from the Issuers are in the form
contemplated by the Indenture, have been duly authorized for issuance and sale
pursuant to this Agreement and the Indenture and, at the Closing Date, will have
been duly executed by the Issuers and, when authenticated in the manner provided
for in the Indenture and delivered against payment of the purchase price
therefor, will constitute valid and binding agreements of the Issuers,
enforceable in accordance with their terms, except as the enforcement thereof
and rights thereunder may be limited by bankruptcy, insolvency, fraudulent
conveyance, reorganization, moratorium or other similar laws relating to or
affecting the rights and remedies of creditors or by general equitable
principles (whether considered in a proceeding at law or in equity), or may be
limited by applicable law or as against public policy, and will be entitled to
the benefits of the Indenture. The Exchange Notes have been duly and validly
authorized for issuance by the Issuers, and when issued and authenticated in
accordance with the terms of the Indenture, the Registration Rights Agreement
and the Exchange Offer, will constitute valid and binding obligations of the
Issuers, enforceable against the Issuers in accordance with their terms, except
as the enforcement thereof and rights thereunder may be limited by bankruptcy,
insolvency, fraudulent conveyance, reorganization, moratorium, or similar laws
relating to or affecting enforcement of the rights and remedies of creditors or
by general principles of equity (whether considered in a proceeding at law or in
equity), or may be limited by applicable law or as against public policy, and
will be entitled to the benefits of the Indenture. The Guarantees of the Notes
are in the form contemplated by the Indenture and, at the Closing Date, will
have been duly authorized for issuance pursuant to this Agreement and the
Indenture and duly executed by each of the Guarantors and, when the Notes have
been authenticated in the manner provided for in the Indenture and delivered
against payment of the purchase price therefor, will constitute valid and
binding agreements of the Guarantors, enforceable in accordance with their
terms, except as the enforcement thereof may be limited by bankruptcy,
insolvency, fraudulent conveyance, reorganization, moratorium or other similar
laws relating to or affecting the rights and remedies of creditors or by general
equitable principles (whether considered in a proceeding at law or in equity),
or may be limited by applicable law or as against public policy, and will be
entitled to the benefits of the Indenture. The Guarantees of the Exchange Notes
are in the form contemplated by the Indenture and, at the Closing Date, will
have been duly and validly authorized for issuance by the Guarantors, and when
issued and authenticated in accordance with the terms of the Indenture, the
Registration Rights Agreement and the Exchange Offer, will constitute valid and
binding obligations of the Guarantors, enforceable against the Guarantors in
accordance with their terms, except as the enforcement thereof and rights
thereunder may be limited by bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium, or similar laws relating to or affecting enforcement
of the rights and remedies of creditors or by general principles of equity
(whether considered in a

                                      -5-



proceeding at law or in equity), or may be limited by applicable law or as
against public policy, and will be entitled to the benefits of the Indenture.

            (h) Authorization of the Indenture. At the Closing Date, the
Indenture will have been duly authorized, executed and delivered by the Issuers
and the Guarantors and will constitute a valid and binding agreement of the
Issuers and the Guarantors, enforceable against the Issuers and the Guarantors
in accordance with its terms, except as the enforcement thereof may be limited
by bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or
other similar laws relating to or affecting the rights and remedies of creditors
or by general equitable principles (whether considered in a proceeding at law or
in equity), or may be limited by applicable law or as against public policy.

            (i) Description of the Securities, the Indenture and the
Registration Rights Agreement. The Notes, the Exchange Notes, the Guarantees,
the guarantees of the Exchange Notes, the Indenture and the Registration Rights
Agreement will conform in all material respects to the respective statements
relating thereto contained in the Offering Memorandum.

            (j) No Material Adverse Change. Except as otherwise disclosed in the
Offering Memorandum, subsequent to the respective dates as of which information
is given in the Offering Memorandum: (i) there has been no material adverse
change, or any development that could reasonably be expected to (A) result in a
material adverse change, in the condition, financial or otherwise, or in the
earnings, business, operations or prospects, whether or not arising from
transactions in the ordinary course of business, of the Issuers and the
Guarantors, considered as one entity and (B) materially and adversely affect the
ability of the Issuers and the Guarantors to perform their obligations pursuant
to documents relating to the Transactions (any such change is called a "Material
Adverse Change"); (ii) the Issuers and the Guarantors, considered as one entity,
have not incurred any material liability or obligation, in any such case, other
than those incurred in connection with the Transactions, indirect, direct or
contingent, not in the ordinary course of business nor entered into any material
transaction or agreement not in the ordinary course of business; and (iii) there
has been no dividend or distribution of any kind declared, paid or made by the
Issuers, except for dividends paid to the Issuers on any class of capital stock
or repurchase or redemption by the Issuers of any class of capital stock.

            (k) Independent Accountants. PricewaterhouseCoopers LLP, which
expressed its opinion with respect to the combined financial statements (which
term as used in this Agreement includes the related notes thereto) included in
the Offering Memorandum, are independent certified public accountants with
respect to the Issuers under Rule 101 of the Code of Professional Conduct of the
American Institute of Certified Public Accountants, and its rulings and
interpretations.

            (l) Preparation of the Financial Statements. The financial
statements, together with the related notes, included in the Offering Memorandum
present fairly in all material respects the combined financial position of AMR
and EmCare and their respective subsidiaries as of and at the dates indicated
and the results of their operations and cash flows for the periods specified,
subject, in the case of interim financial statements, to year-end adjustments.
Such financial statements have been prepared in conformity with generally
accepted accounting princi-

                                      -6-



ples as applied in the United States ("GAAP"), applied on a consistent basis
throughout the periods involved, except as may be expressly stated otherwise in
the related notes thereto. The financial data set forth in the Offering
Memorandum under the captions "Offering Memorandum Summary -- Summary of
Historical Combined and Pro Forma Consolidated Financial Information and Other
Data" and "Selected Combined Financial Information and Other Data" fairly
present the information set forth therein on a basis consistent with that of the
audited and unaudited financial statements contained in the Offering Memorandum.
The pro forma consolidated financial information with respect to the Parent and
the related notes thereto included under the caption "Offering Memorandum
Summary -- Summary of Historical Combined and Pro Forma Consolidated Financial
Information and Other Data" and in "Unaudited Pro Forma Consolidated Financial
Data" in the Offering Memorandum present fairly in all material respects the
information contained therein and have been properly presented in all material
respects on the bases described therein, and the assumptions used in the
preparation thereof are reasonable and the adjustments used therein are
appropriate in all material respects to give effect to the Transactions.

            (m) Incorporation and Good Standing of the Issuers and the
Guarantors. Except as listed in Schedule 1(m) hereto, each of Issuers and the
Guarantors has been duly incorporated or formed and is validly existing as a
corporation, limited liability company or partnership in good standing under the
laws of the jurisdiction of its incorporation or formation and has corporate,
limited liability company or limited partnership power and authority to own,
lease and operate its properties and to conduct its business as described in the
Offering Memorandum and to enter into and perform its obligations relating to
the Transactions, including under each of this Agreement, the Joinder Agreement
(only with respect to the Guarantors, other than the Parent), the Registration
Rights Agreement, the DTC Agreement, the Securities, the Exchange Securities and
the Indenture. Each of the Issuers and the Guarantors is duly qualified as a
foreign corporation, limited liability company or partnership to transact
business and is in good standing in each jurisdiction in which such
qualification is required, whether by reason of the ownership or leasing of
property or the conduct of business, except for such jurisdictions where the
failure to so qualify or to be in good standing would not, individually or in
the aggregate, reasonably be expected to result in a Material Adverse Change.
All of the issued and outstanding capital stock of the Issuers or the Guarantors
has been duly authorized and validly issued, is fully paid and nonassessable
and, at the Closing Date with respect to the Guarantors (other than the Parent),
will be owned by an Issuer, directly or through subsidiaries of an Issuer, free
and clear of any security interest, mortgage, pledge, lien, encumbrance or
claim, other than pursuant to the Credit Documents. At the Closing Date, none of
the Issuers or any of the Guarantors will own or control, directly or
indirectly, any corporation, association or other entity other than the
subsidiaries listed in Schedule 1(m) hereto and other than the Affiliated
Medical Groups (as defined in paragraph (ee) herein).

            (n) Capitalization and Other Capital Stock Matters. At November 30,
2004, on a consolidated basis, after giving pro forma effect to the
Transactions, the Parent would have an authorized and outstanding capitalization
as set forth in the Offering Memorandum under the caption "Capitalization"
(other than for subsequent issuances of partnership interests, if any, pursuant
to employee benefit plans described in the Offering Memorandum).

                                      -7-



            (o) Non-Contravention of Existing Instruments; No Further
Authorizations or Approvals Required. Neither the Issuers nor any of the
Guarantors is in violation of its charter or bylaws or is in default (or, with
the giving of notice or lapse of time, would be in default) ("Default") under
any indenture, mortgage, loan or credit agreement, note, contract, franchise,
lease or other instrument to which either an Issuer or any Guarantor is a party
or by which any of them may be bound or to which any of the property or assets
of an Issuer or any Guarantor is subject (each, an "Existing Instrument"),
except for such Defaults as would not, individually or in the aggregate,
reasonably be expected to result in a Material Adverse Change. At the Closing
Date, the Issuers' and the Guarantors' execution, delivery and performance of
this Agreement, the Joinder Agreement, the Registration Rights Agreement, the
DTC Agreement and the Indenture, as applicable, and the issuance and delivery of
the Securities or the Exchange Securities, and consummation of the Transactions:
(i) will have been duly authorized by all necessary corporate or other action
and will not result in any violation of the provisions of the charter or bylaws
or partnership company agreement of the Issuers or the Guarantors, (ii) will not
conflict with or constitute a breach of, or Default or a Debt Repayment
Triggering Event (as defined below) under, or result in the creation or
imposition of any lien, charge or encumbrance upon any property or assets of the
Issuers or the Guarantors pursuant to, or require the consent of any other party
to, any Existing Instrument, except for such conflicts, breaches, Defaults,
liens, charges or encumbrances listed in Schedule 1(o) hereto or as would not,
individually or in the aggregate, reasonably be expected to result in a Material
Adverse Change, and (iii) will not result in any violation of any law,
administrative regulation or administrative or court decree applicable to the
Issuers or the Guarantors, except as would not, individually or in the
aggregate, reasonably be expected to result in a Material Adverse Change. No
consent, approval, authorization or other order of, or registration or filing
with, any court or other governmental or regulatory authority or agency is
required for the Issuers' or the Guarantors' execution, delivery and performance
of this Agreement, the Joinder Agreement, Senior Secured Credit Facility, the
Registration Rights Agreement, the DTC Agreement or the Indenture, as
applicable, or the issuance and delivery of the Securities or the Exchange
Securities, or consummation of the Transactions except such as have been
obtained or made or will be obtained or made at the Closing Date by the Issuers
or the Guarantors and are in full force and effect under the Securities Act,
applicable securities laws of the several states of the United States and
provinces of Canada and except such as may be required by the securities laws of
the several states of the United States and provinces of Canada with respect to
the Issuers' obligations under the Registration Rights Agreement and, with
respect to AMR's emergency 911 ambulance transport contracts only, except as
would not, individually or in the aggregate, reasonably be expected to result in
a Material Adverse Change. As used herein, a "Debt Repayment Triggering Event"
means any event or condition which gives, or with the giving of notice or lapse
of time would give, the holder of any note, debenture or other evidence of
indebtedness (or any person acting on such holder's behalf) the right to require
the repurchase, redemption or repayment of all or a portion of such indebtedness
by the Issuers or any of their respective subsidiaries.

            (p) No Material Actions or Proceedings. Except as otherwise
disclosed in the Offering Memorandum, there are no legal or governmental
actions, suits or proceedings pending or, to the best of the Issuers' and the
Guarantors' knowledge, threatened (i) against or affecting the Issuers or the
Guarantors or (ii) which have as the subject thereof any property owned or

                                      -8-



leased by the Issuers or the Guarantors and which such action, suit or
proceeding, if determined adversely to the Issuers or such subsidiary, would,
individually or in the aggregate, reasonably be expected to result in a Material
Adverse Change or adversely affect the consummation of the Transactions. Except
as otherwise disclosed in the Offering Memorandum, no material labor dispute
with the employees of the Issuers or any of the Guarantors, or with the
employees of any principal supplier of the Issuers or the Guarantors, exists or,
to the best of the Issuers' or the Guarantors' knowledge, is threatened or
imminent.

            (q) Intellectual Property Rights. Except as otherwise disclosed in
the Offering Memorandum, the Issuers the Guarantors own or possess sufficient
trademarks, trade names, patent rights, copyrights, licenses, approvals, trade
secrets and other similar rights (collectively, "Intellectual Property Rights")
reasonably necessary to conduct their businesses as now conducted; and the
expected expiration of any of such Intellectual Property Rights would not,
individually or in the aggregate, reasonably be expected to result in a Material
Adverse Change. Neither the Issuers nor any of the Guarantors has received any
notice of infringement or conflict with asserted Intellectual Property Rights of
others, which infringement or conflict, if the subject of an unfavorable
decision, would, individually or in the aggregate, reasonably be expected to
result in a Material Adverse Change.

            (r) All Necessary Permits, etc. Except as otherwise disclosed in the
Offering Memorandum, the Issuers and the Guarantors possess such valid and
current certificates, authorizations or permits issued by the appropriate state,
federal or foreign regulatory agencies or bodies necessary to conduct their
respective businesses as now conducted except as would not, individually or in
the aggregate, reasonably be expected to result in a Material Adverse Change,
and neither the Issuers nor any Guarantor has received any notice of proceedings
relating to the revocation or modification of, or non-compliance with, any such
certificate, authorization or permit which, singly or in the aggregate, if the
subject of an unfavorable decision, ruling or finding, would, individually or in
the aggregate, reasonably be expected to result in a Material Adverse Change.

            (s) Title to Properties. Except as otherwise disclosed in the
Offering Memorandum, at the Closing Date the Issuers and each of the Guarantors
will have good and marketable title to all the properties and assets reflected
as owned in the financial statements referred to in Section 1(l) hereof (or
elsewhere in the Offering Memorandum), in each case free and clear of any
security interests, mortgages, liens, encumbrances, equities, claims and other
defects, except pursuant to the Credit Documents and such as would not,
individually or in the aggregate, reasonably be expected to result in a Material
Adverse Change. The real property, improvements, equipment and personal property
held under lease by the Issuers or any Guarantor are held under valid and
enforceable leases, with such exceptions as would not, individually or in the
aggregate, reasonably be expected to result in a Material Adverse Change.

            (t) Tax Law Compliance. Except as otherwise disclosed in the
Offering Memorandum, the Issuers and the Guarantors have filed all necessary
federal, state and foreign income and franchise tax returns and have paid all
taxes required to be paid by any of them and, if due and payable, any related or
similar assessment, fine or penalty levied against any of them, except as would
not, individually or in the aggregate, reasonably be expected to result in a
Mate-

                                      -9-



rial Adverse Change. The Issuers and the Guarantors have made adequate charges,
accruals and reserves in the applicable financial statements referred to in
Section 1(l) hereof in accordance with GAAP in respect of all federal, state and
foreign income and franchise taxes for all periods as to which the tax liability
of the Issuers or any of the Guarantors has not been finally determined.

            (u) Each Issuer and Guarantor Not an "Investment Company". The
Issuers and the Guarantors have been advised of the rules and requirements under
the Investment Company Act of 1940, as amended (the "Investment Company Act,"
which term, as used herein, includes the rules and regulations of the Commission
promulgated thereunder). Neither Issuer nor any Guarantor is, and after receipt
of payment for the Securities neither Issuer nor any Guarantor will be, an
"investment company" within the meaning of the Investment Company Act.

            (v) Insurance. Except as otherwise disclosed in the Offering
Memorandum, including disclosure relating to self-insurance and liability
retention programs, each of the Issuers and the Guarantors are insured by
recognized, financially sound institutions or are insured or self-insured at
prudent and adequate levels with policies in such amounts and with such
deductibles and covering such risks as are generally deemed adequate and
customary for their businesses including, without limitation, policies covering
real and personal property owned or leased by the Issuers and their respective
subsidiaries against theft, damage, destruction, acts of vandalism and
earthquakes. None of the Issuers or any of the Guarantors has any reason to
believe that it will not be able (i) to renew its existing insurance coverage as
and when such policies expire or (ii) upon such expiration, to obtain comparable
coverage from similar institutions as may be necessary or appropriate to conduct
its business as now conducted and at a cost that would not result in a Material
Adverse Change.

            (w) No Price Stabilization or Manipulation. None of the Issuers or
any of the Guarantors has taken and will not take, directly or indirectly, any
action designed to or that might be reasonably expected to cause or result in
stabilization or manipulation of the price of any security of the Issuers to
facilitate the sale or resale of the Securities.

            (x) Solvency. Each of the Issuers and each of the Guarantors is, and
immediately after the Closing Date will be, Solvent. As used herein, the term
"Solvent" means, with respect to any person on a particular date, that on such
date (i) the fair market value of the assets of such person is greater than the
total amount of liabilities (including contingent liabilities) of such person,
(ii) the present fair salable value of the assets of such person is greater than
the amount that will be required to pay the probable liabilities of such person
on its debts as they become absolute and matured, (iii) such person is able to
realize upon its assets and pay its debts and other liabilities, including
contingent obligations, as they mature and (iv) such person does not have
unreasonably small capital.

            (y) Compliance with Environmental Laws. Except as would not,
individually or in the aggregate, reasonably be expected to result in a Material
Adverse Change, (i) none of the Issuers or any of the Guarantors is in violation
of any federal, state, local or foreign law or regulation relating to pollution
or protection of human health or the environment (including, without limitation,
ambient air, surface water, groundwater, land surface or subsurface strata) or

                                      -10-



wildlife, including, without limitation, laws and regulations relating to
emissions, discharges, releases or threatened releases of chemicals, pollutants,
contaminants, wastes, toxic substances, hazardous substances, petroleum and
petroleum products (collectively, "Materials of Environmental Concern"), or
otherwise relating to the manufacture, processing, distribution, use, treatment,
storage, disposal, transport or handling of Materials of Environmental Concern
(collectively, "Environmental Laws"), which violation includes, without
limitation, noncompliance with any permits or other governmental authorizations
required for the operation of the business of the Issuers or their respective
subsidiaries under applicable Environmental Laws, or noncompliance with the
terms and conditions thereof, nor have any of the Issuers or any of their
respective subsidiaries received any written communication, whether from a
governmental authority, citizens group, employee or otherwise, that alleges that
any of the Issuers or any of their respective subsidiaries is in violation of
any Environmental Law; (ii) there is no claim, action or cause of action filed
with a court or governmental authority, no investigation with respect to which
any of the Issuers has received written notice, and no written notice by any
person or entity alleging potential liability for investigatory costs, cleanup
costs, governmental responses costs, natural resources damages, property
damages, personal injuries, attorneys' fees or penalties arising out of, based
on or resulting from the presence, or release into the environment, of any
Material of Environmental Concern at any location owned, leased or operated by
any of the Issuers or any of their respective subsidiaries, now or in the past
(collectively, "Environmental Claims"), pending or, to the best of each Issuer's
knowledge, threatened against any of the Issuers or any of their respective
subsidiaries or any person or entity whose liability for any Environmental Claim
the Issuers or any of their respective subsidiaries has retained or assumed
either contractually or by operation of law; and (iii) to the best of each
Issuer's and the Guarantors' knowledge, there are no past or present actions,
activities, circumstances, conditions, events or incidents, including, without
limitation, the release, emission, discharge, presence or disposal of any
Material of Environmental Concern, that could result in a violation of any
Environmental Law or form the basis of a potential Environmental Claim against
either of the Issuers or any of the Guarantors or against any person or entity
whose liability for any Environmental Claim any of the Issuers or any the
Guarantors has retained or assumed either contractually or by operation of law.

            (z) Periodic Review of Costs of Environmental Compliance. In the
ordinary course of their business, AMR and EmCare conduct a periodic review of
their compliance with Environmental Laws, in the course of which they identify
and evaluate costs and liabilities associated with such compliance. On the basis
of such review and the amount of its established reserves, the Issuers and the
Guarantors have reasonably concluded that such associated costs and liabilities
would not, individually or in the aggregate, reasonably be expected to result in
a Material Adverse Change.

            (aa) ERISA Compliance. Except as would not, individually or in the
aggregate, reasonably be expected to result in a Material Adverse Change, the
Issuers and the Guarantors and any "employee benefit plan" (as defined under the
Employee Retirement Income Security Act of 1974 (as amended, "ERISA," which
term, as used herein, includes the regulations and published interpretations
thereunder) established or maintained by the Issuers, the Guarantors or their
"ERISA Affiliates" (as defined below) are in compliance with ERISA. "ERISA
Affiliate" means, with respect to the Issuers or any Guarantor, any member of
any group of organizations

                                      -11-



described in Section 414 of the Internal Revenue Code of 1986 (as amended,
"Code," which term, as used herein, includes the regulations and published
interpretations thereunder) of which the Issuers or such Guarantor is a member.
No "reportable event" (as defined under ERISA) has occurred or is reasonably
expected to occur with respect to any "employee benefit plan" established or
maintained by the Issuers, the Guarantors or any of their ERISA Affiliates. No
"employee benefit plan" established or maintained by the Issuers and the
Guarantors or any of their ERISA Affiliates, if such "employee benefit plan"
were terminated, would have any "amount of unfunded benefit liabilities" (as
defined under ERISA). No prohibited transaction, within the meaning of Section
406 of ERISA or Section 4975 of the Code, has occurred with respect to any such
plan excluding transactions effected pursuant to a statutory or administrative
exemption. Neither the Issuers, the Guarantors nor any of their ERISA Affiliates
has incurred or reasonably expects to incur any liability under (i) Title IV of
ERISA with respect to termination of, or withdrawal from, any "employee benefit
plan" or (ii) Sections 412, 4971, 4975 or 4980B of the Code. Each "employee
benefit plan" established or maintained by the Issuers and the Guarantors or any
of their ERISA Affiliates that is intended to be qualified under Section 401 of
the Code is so qualified and nothing has occurred, whether by action or failure
to act, which would cause the loss of such qualification.

            (bb) Compliance with Labor Laws. Except as disclosed in the Offering
Memorandum and except as would not, individually or in the aggregate, reasonably
be expected to result in a Material Adverse Change, (i) there is (A) no unfair
labor practice complaint pending or, to the best of the Issuers' and the
Guarantors' knowledge, threatened against the Issuers or any of the Guarantors
before the National Labor Relations Board, and no grievance or arbitration
proceeding arising out of or under collective bargaining agreements pending, or
to the best of the Issuers' and the Guarantors' knowledge, threatened, against
the Issuers or any of their respective subsidiaries, (B) no strike, labor
dispute, slowdown or stoppage pending or, to the best of the Issuers' knowledge,
threatened against the Issuers or any of the Guarantors and (C) no union
representation question existing with respect to the employees of the Issuers or
any of their respective subsidiaries and, to the best of the Issuers' and the
Guarantors' knowledge, no union organizing activities taking place and (ii)
there has been no violation of any federal, state or local law relating to
discrimination in hiring, promotion or pay of employees or of any applicable
wage or hour laws.

            (cc) Forward-Looking Statements. No forward-looking statement
(within the meaning of Section 27A of the Securities Act and Section 21E of the
Exchange Act) in the Preliminary Offering Memorandum or the Offering Memorandum
has been made without a reasonable basis or has been disclosed other than in
good faith.

            (dd) Statistical and Market Data. Nothing has come to the attention
of either of the Issuers that has caused such Issuer to believe that the
statistical and market-related data included in the Preliminary Offering
Memorandum and the Offering Memorandum is not based on or derived from sources
that are reliable or derived by the Issuers and the Guarantors in good faith.

            (ee) Compliance With Health Care Statutes, Rules and Regulations.
Except as disclosed in the Offering Memorandum or except for such violations
that would not, individually

                                      -12-



or in the aggregate, reasonably be expected to result in a Material Adverse
Change, to either the Issuers' or any of the Guarantors' knowledge, neither of
the Issuers nor any of the Guarantors has violated any federal, state or local
health care statutes, rules or regulations, including, but not limited to, the
Federal False Claims Act, the Federal Anti-Kickback Statute, the Federal
Self-Referral Law, the Health Insurance Portability and Accountability Act of
1996, and any corresponding or similar state laws (collectively, the "Health
Care Statutes, Rules and Regulations"). Except as disclosed in the Offering
Memorandum or except for such violations which would not, individually or in the
aggregate, reasonably be expected to result in a Material Adverse Change, to the
best of the Issuers' and the Guarantors' knowledge, the Issuers, the Guarantors,
and any affiliated entity, including without limitation any professional
corporation, partnership or association, with which any of the Issuers or any of
the Guarantors contracts and through which services are provided (each, an
"Affiliated Medical Group" and collectively, the "Affiliated Medical Groups")
has received any indication or notice, written or oral, from any other federal
or state agency or authority that they have or are alleged to have acted
contrary to any Health Care Statute, Rule or Regulation. To the best of the
Issuers' and the Guarantors' knowledge and except for such violations which
would not, individually or in the aggregate, reasonably be expected to result in
a Material Adverse Change, the Issuers, the Guarantors and the Affiliated
Medical Groups are in material compliance with the laws and regulations
pertaining to (i) physician licensure, (ii) the corporate practice of medicine,
and (iii) physician fee-splitting in all states in which they operate. To the
best of the Issuers' and the Guarantors' knowledge, no Affiliated Medical Group
or any individual or business entity with which an Affiliated Medical Group
contracts has received any indication or notice, written or oral, from
representatives of the United States Department of Health and Human Services or
any other federal or state agency regarding any matters, relating to the
revocation, suspension, termination or modification of any applicable license,
certification, accreditation, supplier or provider number, or ability to
participate in any federally funded or other health care program. Issuers and
their respective subsidiaries are subject to a Compliance Program that has been
structured in light of what constitutes an effective compliance program as
defined in the United States Sentencing Commission Guidelines.

            (ff) Related Party Transactions. Except as disclosed on Schedule
1(ff) hereto, to the Issuers' and the Guarantors' knowledge, no relationship,
direct or indirect, exists between or among any of the Issuers or any affiliate
of the Issuers, on the one hand, and any director, executive officer, member or
stockholder of the Issuers or any affiliate of the Issuers, on the other hand,
which would be required by the Securities Act to be disclosed in a registration
statement on Form S-1 which is not so disclosed in the Offering Memorandum.
There are no outstanding loans, advances (except advances for business expenses
in the ordinary course of business) or guarantees of indebtedness by the Issuers
or any affiliate of the Issuers to or for the benefit of any of the officers or
directors of the Issuers or any affiliate of the Issuers or any of their
respective family members.

            (gg) No Unlawful Contributions or Other Payments. Except as would
not, individually or in the aggregate, reasonably be expected to result in a
Material Adverse Change, none of the Issuers, any Guarantor or, to the best of
the Issuers' and the Guarantors' knowledge, any employee or agent of the Issuers
or any Guarantor, has made any contribution or other pay-

                                      -13-



ment to any official of, or candidate for, any federal, state or foreign office
in violation of any law.

            (hh) No Default in Senior Debt. Except as disclosed in Schedule
1(hh) hereto, no event of default exists under any material contract, indenture,
mortgage, loan agreement, note, lease or other agreement or instrument
constituting Senior Debt (as defined in the Indenture).

            (ii) Senior Secured Credit Facility. At the Closing Date, the Senior
Secured Credit Facility will have been duly and validly authorized by the
Issuers and the Guarantors and, when duly executed and delivered by the Issuers
and the Guarantors, will be the valid and legally binding obligation of the
Issuers and the Guarantors, enforceable in accordance with its terms, except as
the enforcement thereof and rights thereunder may be limited by bankruptcy,
insolvency, fraudulent conveyance, reorganization, moratorium or other similar
laws relating to or affecting the rights and remedies of creditors or by general
equitable principles (whether considered in a proceeding at law or in equity),
or may be limited by applicable law or as against public policy.

            (jj) Regulation S. The Issuers, the Guarantors and their respective
Affiliates and all persons acting on their behalf (other than the Initial
Purchasers, as to whom the Issuers and the Guarantors make no representation)
have complied with and will comply with the offering restrictions requirements
of Regulation S in connection with the offering of the Securities outside the
United States and, in connection therewith, the Offering Memorandum will contain
the disclosure required by Rule 902 thereof. The Securities sold in reliance on
Regulation S will be represented upon issuance by a temporary global security
that may not be exchanged for definitive securities until the expiration of the
40-day restricted period referred to in Rule 903 of the Securities Act and only
upon certification of beneficial ownership of such Securities by non-U.S.
persons or U.S. persons who purchased such Securities in transactions that were
exempt from the registration requirements of the Securities Act.

            (kk) Internal Controls. AMR and EmCare, on a consolidated basis,
maintain a system of internal accounting controls sufficient to provide
reasonable assurance that, in all material respects: (i) transactions are
executed in accordance with management's general or specific authorizations;
(ii) transactions are recorded as necessary to permit preparation of financial
statements in conformity with generally accepted accounting principles and to
maintain asset accountability; (iii) access to assets is permitted only in
accordance with management's general or specific authorization; and (iv) the
recorded accountability for assets is compared with the existing assets at
reasonable intervals and appropriate action is taken with respect to any
differences. None of the Issuers or the Targets is subject to the reporting
requirements of the Exhange Act or to Item 307 or 308 of Regulation S-K.

            (ll) Officer's Certificate. Any certificate signed by an officer of
the Issuers or any Guarantor and delivered to the Initial Purchasers or to
counsel for the Initial Purchasers pursuant to this Agreement shall be deemed to
be a representation and warranty by the Issuers or such Guarantor to each
Initial Purchaser as to the matters set forth therein.

                                      -14-

            (a) The Notes. Each of the Issuers agrees to issue and sell to the
Initial Purchasers, severally and not jointly, all of the Notes upon the terms

Supplements. Prior to amending or supplementing the Offering Memorandum, the
Issuers shall furnish to the Initial Purchasers for review a copy of each such
proposed amendment or supplement, and the

                                      -15-

Initial Purchasers reasonably object in writing within three business days of

            (b) Amendments and Supplements to the Offering Memorandum and Other
Securities Act Matters. If, prior to the completion of the placement of the
Securities by the Initial Purchasers with the Subsequent Purchasers, any event
shall occur or condition exist as a result of which it is necessary to amend or
supplement the Offering Memorandum in order to make the statements therein, in
the light of the circumstances when the Offering Memorandum is delivered to a
Subsequent Purchaser, not misleading, or if in the judgment of the Initial
Purchasers or counsel for the Initial Purchasers it is otherwise necessary to
amend or supplement the Offering Memorandum to comply with law, the Issuers
agree to promptly prepare (subject to Section 3(a) hereof), and furnish at its
own expense to the Initial Purchasers, amendments or supplements to the Offering
Memorandum so that the statements in the Offering Memorandum as so amended or
supplemented will not, in the light of the circumstances when the Offering
Memorandum is delivered to a Subsequent Purchaser, be misleading or so that the
Offering Memorandum, as amended or supplemented, will comply with law.

            The Issuers hereby expressly acknowledge that the indemnification
and contribution provisions of Sections 8 and 9 hereof are specifically
applicable and relate to each offering memorandum, registration statement,
prospectus, amendment or supplement referred to in this Section 3.

            (c) Copies of the Offering Memorandum. The Issuers agree to furnish

            (d) Blue Sky Compliance. Each of the Issuers and the Guarantors
shall cooperate with the Initial Purchasers and counsel for the Initial

registering) all or any part of the Securities for offer and sale under the
securities laws of the several states of the United States, the provinces of
Canada or any other jurisdictions designated by the Initial Purchasers, shall
comply with such laws and shall continue such qualifications, registrations and
exemptions in effect so long as required for the distribution of the Securities;
provided that none of the Issuers or any of the Guarantors shall be required to

Issuers will advise the Initial Purchasers promptly of the suspension of the
qualification or registration of (or any such exemption relating to) the

or threat of any proceeding for any such purpose, and in the event of the

moment.

                                      -16-

            (g) Additional Issuer Information. At any time when the Issuers are

Securities and prospective purchasers of Securities information ("Additional
Issuer Information") satisfying the requirements of Rule 144A(d)(4).

            (h) Future Reports to the Initial Purchasers. At any time when the
Issuers or the Guarantors are not subject to Section 13 or 15 of the Exchange

(i) as soon as practicable after the end of each fiscal year, copies of the

            (i) No Integration. The Issuers agree that they will not and will
cause their respective Affiliates not to make any offer or sale of securities of
the Issuers of any class if, as a result of the doctrine of "integration"
referred to in Rule 502 under the Securities Act, such offer or sale would
render invalid (for the purpose of (i) the sale of the Securities by the Issuers
to the Initial Purchasers, (ii) the resale of the Securities by the Initial
Purchasers to Subsequent Purchasers or (iii) the resale of the Securities by
such Subsequent Purchasers to others) the exemption from the registration

efforts to cause such Notes to be eligible for the PORTAL Market.

            (l) No Resales by the Issuers. Until the issuance of the Exchange
Securities, the Issuers will not, and will use commercially reasonable efforts
to cause their affiliates (as defined in Rule 144 under the Securities Act) to,
resell any of the Securities that have been acquired by any of them, except for
Securities purchased by the Issuers or any of their affiliates and resold in a
transaction registered under the Securities Act.

                                      -17-

laws of the several states of the United States, the provinces of Canada or
other jurisdictions designated by the Initial Purchasers (including, without
limitation, the cost of preparing, printing and mailing preliminary and final

The obligations of the several Initial Purchasers to purchase and pay for the

            Section 6. Reimbursement of Initial Purchasers' Expenses. If this
Agreement is terminated by the Initial Purchasers pursuant to Section 5 or 10
hereof, including if the sale to the Initial Purchasers of the Securities on the
Closing Date is not consummated because of any refusal, inability or failure on

agreement herein or to comply with any provision hereof, the Issuers and the
Guarantors, jointly and severally, agree to reimburse the Initial Purchasers (or
such Initial Purchasers as have terminated this Agreement with respect to
themselves), severally, upon demand for all out-of-pocket expenses that shall
have been reasonably incurred by the Initial Purchasers in connection with the
proposed purchase and the offering and sale of the Securities, including,

on the other hand, hereby agree to observe the following procedures in
connection with the offer and sale of the Securities:

            (A) Offers and sales of the Securities will be made only by the
      Initial Purchasers or Affiliates thereof qualified to do so in the
      jurisdictions in which such offers or sales are made. Each such offer or
      sale shall only be made to persons whom the offeror or seller reasonably
      believes to be Qualified Institutional Buyers or non-U.S. persons outside
      the United States to whom the offeror or seller reasonably believes offers
      and sales of the Securities may be made in reliance upon Regulation S upon
      the terms and conditions set forth in Annex I hereto, which Annex I is
      hereby expressly made a part hereof.

            (B) The Securities will be offered by approaching prospective
      Subsequent Purchasers on an individual basis. No general solicitation or
      general advertising (within the meaning of Rule 502 under the Securities
      Act) will be used in the United States in connection with the offering of
      the Securities.

            (C) Upon original issuance by the Issuers, and until such time as
      the same is no longer required under the applicable requirements of the
      Securities Act, the Securities (and all securities issued in exchange
      therefor or in substitution thereof, other than the Exchange Securities)
      shall bear the following legend:

                                      -22-



            Following the sale of the Securities by the Initial Purchasers to
Subsequent Purchasers pursuant to the terms hereof, the Initial Purchasers shall
not be liable or responsible to the Issuers for any losses, damages or
liabilities suffered or incurred by the Issuers, including any losses, damages
or liabilities under the Securities Act, arising from or relating to any resale
or transfer of any Security.

            Section 8. Indemnification.

            (a) Indemnification of the Initial Purchasers. Each of the Issuers
and each of the Guarantors, jointly and severally, agrees to indemnify and hold
harmless each Initial Purchaser, its affiliates, directors, officers and
employees, and each person, if any, who controls any Initial Purchaser within
the meaning of the Securities Act and the Exchange Act against any loss, claim,
damage, liability or expense, as incurred, to which such Initial Purchaser,
affiliate, director, officer, employee or controlling person may become subject,
under the Securities Act, the Exchange Act or other federal or state statutory
law or regulation, or at common law or otherwise (including in settlement of any
litigation, if such settlement is effected with the written consent of the
Issuers), insofar as such loss, claim, damage, liability or expense (or actions
in respect thereof as contemplated below) arises out of or is based: (i) upon
any untrue statement or alleged untrue statement of a material fact contained in
any Preliminary Offering Memorandum or the Offering Memorandum (or any amendment
or supplement thereto), or the omission or alleged omission therefrom of a
material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading; or (ii) in whole
or in part upon any inaccuracy in the representations and warranties of the
Issuers contained herein; or (iii) in whole or in part upon any failure of the
Issuers to perform their obligations hereunder or under law; or (iv) any act or
failure to act or any alleged act or failure to act by any Initial Purchaser in
connection with, or relating in any manner to, the offering contemplated hereby,
and which is included as part of or referred to in any loss, claim, damage,
liability or action arising out of or based upon any matter covered by clause
(i) above to the extent such loss, claim, damage, liability or expense is not
covered in items (i) through (iii) (subject to the limitations set forth below),
provided that the Issuers shall not be liable under this clause (iv) to the
extent that a court of competent jurisdiction shall have determined by a final
judgment that such loss, claim, damage, liability or action resulted directly
from any such acts or failures to act undertaken or omitted to be taken by such
Initial Purchaser through its gross negligence or willful misconduct; and to
reimburse each Initial Purchaser and each such director, officer, employee or
controlling person for any and all expenses (including the reasonable fees and
disbursements of counsel chosen by Banc of America Securities LLC) as such
expenses are reasonably incurred by such Initial Purchaser or such director,
officer, employee or controlling person in connection with investigating,
defending, settling, compromising or paying any such loss, claim, damage,
liability, expense or action; provided, however, that the foregoing indemnity
agreement shall not apply to any loss, claim, damage, liability or expense to
the extent, but only to the extent, arising out of or based upon any untrue
statement or alleged untrue statement or omission or alleged omission made in
reliance upon and in conformity with written information furnished to the
Issuers by the Initial Purchasers expressly for use in any Preliminary Offering
Memorandum or the Offering Memorandum (or any amendment or supplement thereto).
The indemnity agreement set forth in this Section 8(a) shall be in addition to
any liabilities that the Issuers may otherwise have.

                                      -23-



            (b) Indemnification of the Issuers and the Guarantors. Each Initial
Purchaser agrees, severally and not jointly, to indemnify and hold harmless the
Issuers, each Guarantor, each of their directors and each person, if any, who
controls the Issuers within the meaning of the Securities Act or the Exchange
Act, against any loss, claim, damage, liability or expense, as incurred, to
which the Issuers, any Guarantor or any such director or controlling person may
become subject, under the Securities Act, the Exchange Act, or other federal or
state statutory law or regulation, or at common law or otherwise (including in
settlement of any litigation, if such settlement is effected with the written
consent of such Initial Purchaser), insofar as such loss, claim, damage,
liability or expense (or actions in respect thereof as contemplated below)
arises out of or is based upon any untrue statement or alleged untrue statement
of a material fact contained in any Preliminary Offering Memorandum or the
Offering Memorandum (or any amendment or supplement thereto), or arises out of
or is based upon the omission or alleged omission therefrom of a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading, in each case to the
extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in any Preliminary Offering
Memorandum or the Offering Memorandum (or any amendment or supplement thereto),
in reliance upon and in conformity with written information furnished to the
Issuers by such Initial Purchaser expressly for use therein; and to reimburse
the Issuers, any Guarantor and each such director or controlling person for any
and all expenses (including the fees and disbursements of counsel) as such
expenses are reasonably incurred by the Issuers, any Guarantor or such director
or controlling person in connection with investigating, defending, settling,
compromising or paying any such loss, claim, damage, liability, expense or
action. The Issuers and the Guarantors hereby acknowledge that the only
information that the Initial Purchasers have furnished to the Issuers expressly
for use in any Preliminary Offering Memorandum or the Offering Memorandum (or
any amendment or supplement thereto) is the statements set forth in the third
sentence of the third paragraph under the caption "Risk Factors -- Risk Factors
Related to the Notes -- The notes are subject to restrictions on transfer. If an
active trading market does not develop for these notes, you may not be able to
resell them" and the third sentence of the seventh paragraph and ninth paragraph
under the caption "Plan of Distribution" in the Offering Memorandum. The
indemnity agreement set forth in this Section 8(b) shall be in addition to any
liabilities that each Initial Purchaser may otherwise have.

            (c) Notifications and Other Indemnification Procedures. Promptly
after receipt by an indemnified party under this Section 8 of notice of the
commencement of any action, such indemnified party will, if a claim in respect
thereof is to be made against an indemnifying party under this Section 8, notify
the indemnifying party in writing of the commencement thereof, but the omission
so to notify the indemnifying party will not relieve it from any liability which
it may have to any indemnified party for contribution or otherwise than under
the indemnity agreement contained in this Section 8 or to the extent it is not
materially prejudiced as a proximate result of such failure. In case any such
action is brought against any indemnified party and such indemnified party seeks
or intends to seek indemnity from an indemnifying party, the indemnifying party
will be entitled to participate in and, to the extent that it shall elect,
jointly with all other indemnifying parties similarly notified, by written
notice delivered to the indemnified party promptly after receiving the aforesaid
notice from such indemnified party, to assume the defense thereof with counsel
reasonably satisfactory to such indemnified party; pro-

                                      -24-



vided, however, if the defendants in any such action include both the
indemnified party and the indemnifying party and the indemnified party shall
have reasonably concluded that a conflict may arise between the positions of the
indemnifying party and the indemnified party in conducting the defense of any
such action or that there may be legal defenses available to it and/or other
indemnified parties which are different from or additional to those available to
the indemnifying party, the indemnified party or parties shall have the right to
select separate counsel to assume such legal defenses and to otherwise
participate in the defense of such action on behalf of such indemnified party or
parties. Upon receipt of notice from the indemnifying party to such indemnified
party of such indemnifying party's election so to assume the defense of such
action and approval by the indemnified party of counsel, the indemnifying party
will not be liable to such indemnified party under this Section 8 for any legal
or other expenses subsequently incurred by such indemnified party in connection
with the defense thereof unless (i) the indemnified party shall have employed
separate counsel in accordance with the proviso to the next preceding sentence
(it being understood, however, that the indemnifying party shall not be liable
for the expenses of more than one separate counsel (together with local
counsel), approved by the indemnifying party (Banc of America Securities LLC in
the case of Sections 8(b) and 9 hereof), representing the indemnified parties
who are parties to such action) or (ii) the indemnifying party shall not have
employed counsel satisfactory to the indemnified party to represent the
indemnified party within a reasonable time after notice of commencement of the
action, in each of which cases the fees and expenses of counsel shall be at the
expense of the indemnifying party.

            (d) Settlements. The indemnifying party under this Section 8 shall
not be liable for any settlement of any proceeding effected without its written
consent, but if settled with such consent or if there be a final judgment for
the plaintiff, the indemnifying party agrees to indemnify the indemnified party
against any loss, claim, damage, liability or expense by reason of such
settlement or judgment. Notwithstanding the foregoing sentence, if at any time
an indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel as contemplated by this
Section 8, the indemnifying party agrees that it shall be liable for any
settlement of any proceeding effected without its written consent if (i) such
settlement is entered into more than 45 days after receipt by such indemnifying
party of the aforesaid request, (ii) such indemnifying party shall have received
notice of the final terms of such proposed settlement as soon as reasonably
practicable prior to such settlement being entered into and (iii) such
indemnifying party shall not have reimbursed the indemnified party in accordance
with such request prior to the date of such settlement; provided, however, that
the indemnifying party shall not be liable for any reimbursement to the
indemnified party for fees and expenses of counsel pursuant to this sentence to
the extent that, and only for so long as, the indemnifying party actively and
continuously contests such reimbursement in good faith, it being understood that
the any portion of such reimbursement not so contested shall be payable
immediately. No indemnifying party shall, without the prior written consent of
the indemnified party, effect any settlement, compromise or consent to the entry
of judgment in any pending or threatened action, suit or proceeding in respect
of which any indemnified party is or could have been a party and indemnity was
or could have been sought hereunder by such indemnified party, unless such
settlement, compromise or consent includes an unconditional release of such
indemnified party from all liability on claims that are the subject matter of
such action, suit or proceeding and

                                      -25-



does not include any findings of fault, culpability or failure to act by or on
behalf of any indemnified person.

            Section 9. Contribution. If the indemnification provided for in
Section 8 hereof is for any reason held to be unavailable to or otherwise
insufficient to hold harmless an indemnified party in respect of any losses,
claims, damages, liabilities or expenses referred to therein, then each
indemnifying party shall contribute to the aggregate amount paid or payable by
such indemnified party, as incurred, as a result of any losses, claims, damages,
liabilities or expenses referred to therein (i) in such proportion as is
appropriate to reflect the relative benefits received by the Issuers, on the one
hand, and the Initial Purchasers, on the other hand, from the offering of the
Securities pursuant to this Agreement or (ii) if the allocation provided by
clause (i) above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the Issuers, on the one hand, and the
Initial Purchasers, on the other hand, in connection with the statements or
omissions or inaccuracies in the representations and warranties herein which
resulted in such losses, claims, damages, liabilities or expenses, as well as
any other relevant equitable considerations. The relative benefits received by
the Issuers and the Guarantors, on the one hand, and the Initial Purchasers, on
the other hand, in connection with the offering of the Securities pursuant to
this Agreement shall be deemed to be in the same respective proportions as the
total net proceeds from the offering of the Securities pursuant to this
Agreement (before deducting expenses) received by the Issuers, and the total
discount received by the Initial Purchasers bear to the aggregate initial
offering price of the Securities. The relative fault of the Issuers and the
Guarantors, on the one hand, and the Initial Purchasers, on the other hand,
shall be determined by reference to, among other things, whether any such untrue
or alleged untrue statement of a material fact or omission or alleged omission
to state a material fact or any such inaccurate or alleged inaccurate
representation or warranty relates to information supplied by the Issuers and
the Guarantors, on the one hand, or the Initial Purchasers, on the other hand,
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission or inaccuracy.

            The amount paid or payable by a party as a result of the losses,
claims, damages, liabilities and expenses referred to above shall be deemed to
include, subject to the limitations set forth in Section 8 hereof, any legal or
other fees or expenses reasonably incurred by such party in connection with
investigating or defending any action or claim. The provisions set forth in
Section 8 hereof with respect to notice of commencement of any action shall
apply if a claim for contribution is to be made under this Section 9; provided,
however, that no additional notice shall be required with respect to any action
for which notice has been given under Section 8 hereof for purposes of
indemnification.

            The Issuers, the Guarantors and the Initial Purchasers agree that it
would not be just and equitable if contribution pursuant to this Section 9 were
determined by pro rata allocation (even if the Initial Purchasers were treated
as one entity for such purpose) or by any other method of allocation which does
not take account of the equitable considerations referred to in this Section 9.

                                      -26-



            Notwithstanding the provisions of this Section 9, no Initial
Purchaser shall be required to contribute any amount in excess of the discount
received by such Initial Purchaser in connection with the Securities distributed
by it. No person guilty of fraudulent misrepresentation (within the meaning of
Section 11 of the Securities Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation. The Initial
Purchasers' obligations to contribute pursuant to this Section 9 are several,
and not joint, in proportion to their respective commitments as set forth
opposite their names in Schedule A. For purposes of this Section 9, each
affiliate, director, officer and employee of an Initial Purchaser and each
person, if any, who controls an Initial Purchaser within the meaning of the
Securities Act and the Exchange Act shall have the same rights to contribution
as such Initial Purchaser, and each director of each of the Issuers or any
Guarantor, and each person, if any, who controls the Issuers or any Guarantor
with the meaning of the Securities Act and the Exchange Act shall have the same
rights to contribution as the Issuers and the Guarantors.

            Section 10. Termination of This Agreement. Prior to the Closing
Date, this Agreement may be terminated by the Initial Purchasers by notice given
to the Issuers if at any time: (i) trading or quotation in any of the Parent's
or the Issuers' securities shall have been suspended or limited by the
Commission, or trading in securities generally on either the NASDAQ Stock Market
or the New York Stock Exchange shall have been suspended or limited, or minimum
or maximum prices shall have been generally established on any of such quotation
system or stock exchange by the Commission or the NASD; (ii) a general banking
moratorium shall have been declared by any of federal, New York or Delaware
authorities; (iii) there shall have occurred any outbreak or escalation of
national or international hostilities or any crisis or calamity, or any change
in the United States or international financial markets, or any substantial
change or development involving a prospective substantial change in United
States or international political, financial or economic conditions, as in the
judgment of the Initial Purchasers is material and adverse and makes it
impracticable or inadvisable to proceed with the offer, sale or delivery of the
Securities in the manner and on the terms described in the Offering Memorandum

from any of the Initial Purchasers merely by reason of such purchase.

            Section 14. Partial Unenforceability. The invalidity or

GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF
NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN SUCH STATE WITHOUT
REGARD TO CONFLICTS OF LAW PRINCIPLES THEREOF.

            Section 16. Consent to Jurisdiction. Any legal suit, action or
proceeding arising out of or based upon this Agreement or the Transactions
("Related Proceedings") may be instituted in the federal courts of the United
States of America located in the City and County of New York or the courts of
the State of New York in each case located in the City and County of New York
(collectively, the "Specified Courts"), and each party irrevocably submits to
the exclusive jurisdiction (except for suits, actions, or proceedings instituted
in regard to the enforcement of a judgment of any Specified Court in a Related
Proceeding, as to which such jurisdiction is non-exclusive) of such Specified
Courts in any Related Proceeding. Service of any process, summons, notice or
document by mail to such party's address set forth above shall be effective
service of process for any Related Proceeding brought in any Specified Court.
The parties irrevocably and unconditionally waive any objection to the laying of

            Section 17. Default of One or More of the Several Initial
Purchasers. If any one or more of the several Initial Purchasers shall fail or
refuse to purchase Securities that it or they have agreed to purchase hereunder
on the Closing Date, and the aggregate number of Securities which such
defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused
to purchase does not exceed 10% of the aggregate number of the Securities to be
purchased on such date, the other Initial Purchasers shall be obligated,
severally, in the proportions that the number of Securities set forth opposite
their respective names in Schedule A bears to the aggregate number of Securities
set forth opposite the names of all such non-defaulting Initial Purchasers, or
in such other proportions as may be specified by the Initial Purchasers with the
consent of the non-defaulting Initial Purchasers, to purchase the Securities
which such defaulting Initial Purchaser or Initial Purchasers agreed but failed
or refused to purchase on the Closing Date. If any one or more of the Initial
Purchasers shall fail or refuse to purchase Securities and the aggregate number
of Securities with respect to which such default occurs exceeds 10% of the
aggregate number of

                                      -29-



Securities to be purchased on the Closing Date, and arrangements satisfactory to
the Initial Purchasers and the Issuers for the purchase of such Securities are
not made within 48 hours after such default, this Agreement shall terminate
without liability of any party to any other party except that the provisions of
Sections 4, 6, 8 and 9 hereof shall at all times be effective and shall survive
such termination. In any such case either the Initial Purchasers or the Issuers
shall have the right to postpone the Closing Date, as the case may be, but in no
event for longer than seven days in order that the required changes, if any, to
the Offering Memorandum or any other documents or arrangements may be effected.

            As used in this Agreement, the term "Initial Purchaser" shall be
deemed to include any person substituted for a defaulting Initial Purchaser
under this Section 17. Any action taken under this Section 17 shall not relieve
any defaulting Initial Purchaser from liability in respect of any default of
such Initial Purchaser under this Agreement.

            Section 18. The Guarantors. On and effective as of the Closing Date,
each of AMR and EmCare and their respective domestic subsidiaries as of the
Closing Date will assume the obligations of a Guarantor pursuant to this
Agreement by executing a Joinder Agreement.

            Section 19. General Provisions. This Agreement constitutes the
entire agreement of the parties to this Agreement and supersedes all prior
written or oral and all contemporaneous oral agreements, understandings and
negotiations with respect to the subject matter hereof. This Agreement may be
executed in two or more counterparts, each one of which shall be an original,
with the same effect as if the signatures thereto and hereto were upon the same

all of the parties hereto, and no condition herein (express or implied) may be
waived unless waived in writing by each party whom the condition is meant to
benefit. The section headings herein are for the convenience of the parties only
and shall not affect the construction or interpretation of this Agreement.

                                  Exhibit A-2


                                                                       EXHIBIT A

   such counsel and fairly present and summarize, in all material respects, the
   matters referred to therein.

            14) No consent, approval, authorization or other order of, or
   registration or filing with, any court or other governmental or regulatory
   authority of the federal government of the United States or the State of New
   York or any court or other governmental or regulatory authority acting
   pursuant to the General Corporation Law of the State of Delaware, is required
   for the Issuers' execution, delivery and performance of the Purchase
   Agreement, the Registration Rights Agreement, the DTC Agreement or the
   Indenture, or the issuance and delivery of the Securities or the Exchange
   Securities, except as may be required under the Securities Act, the Exchange
   Act, the Trust Indenture Act, and applicable state securities or blue sky
   laws and foreign securities laws.

            15) The execution and delivery of the Purchase Agreement, the

   the Issuers of their obligations thereunder (other than performance by the
   Issuers of their obligations under the indemnification and contribution
   sections of such agreements, as to which we express no opinion): (a) will not
   result in any violation of the provisions of the Organizational Documents of
   the Issuers or any Specified Guarantor; (b) will not result in a breach of or
   a default under the Senior Secured Credit Facility; or (c) to the best of our
   knowledge, assuming the proceeds of borrowings under the Senior Secured
   Credit Facility and/or the issuance and sale of the Notes are used as
   described in the section captioned "Use of Proceeds" in the Offering
   Memorandum, will not contravene any of the Opining Laws.

            16) The Issuers are not, and after receipt of payment for the
   Securities will not be, an "investment company" within the meaning of
   Investment Company Act.

            17) Assuming the accuracy of the representations, warranties and
   covenants of the Issuers and the Initial Purchasers contained in the Purchase
   Agreement, no registration of the Notes or the Guarantees under the
   Securities Act, and no qualification of an indenture under the Trust
   Indenture Act with respect thereto, is required in connection with the
   purchase of the Securities by the Initial Purchasers or the initial resale of
   the Securities by the Initial Purchasers to Qualified Institutional Buyers in
   the manner contemplated by the Purchase Agreement and the Offering Memorandum
   other than any registration or qualification that may be required in
   connection with the Exchange Offer contemplated by the Offering Memorandum or
   in connection with the Registration Rights Agreement.

            During the course of the preparation of the Offering Memorandum, we
have participated in conferences with officers and other representatives of the
Issuers, representatives of the independent public accountants for the Issuers
and representatives of the Initial Purchaser. While we have not undertaken to
determine independently and do not assume any responsibility

                                  Exhibit A-3


                                                                       EXHIBIT A

for the accuracy, completeness or fairness of the statements contained in the
Offering Memorandum and have made no independent check or verification thereof
(except in each case as set forth above), based on these conferences and our
review of the documents referenced above, nothing has come to our attention that
would lead us to believe that the Offering Memorandum (except for financial
data, statements and related notes, the financial statement schedules and the
other financial, accounting and statistical data included therein, as to which
we express no view) at January __, 2005 or as of the date hereof, included or
includes any untrue statement of a material fact or omitted or omits to state a
material fact necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading. We note that our
practice in general and our engagement by the Issuers does not include
Healthcare Laws, and we do not purport to be experts in such laws.

                                  Exhibit A-4


                                                                       EXHIBIT B

            Opinion of local counsel for the Issuers to be delivered pursuant to
Section 5(c)(ii) of the Purchase Agreement.

      The Company(1) has been duly incorporated and is validly existing and in
good standing under the laws of the State of [     ].

      (ii) The Company has all necessary corporate power and authority to

the Company.

      (iv) The Joinder Agreement to the Purchase Agreement has been duly
authorized, executed and delivered by the Company.

and delivered by the Company.

      (vi) The Company has duly authorized and executed its guarantee of the

      (vii) The Company has duly authorized its guarantee of the Exchange Notes.

      (viii) The issuance of the Guarantee by the Company, the execution,
delivery and compliance by the Company with all of the provisions of the
Transaction Documents and the performance of its obligations thereunder will not
result in a violation of the certificate of incorporation, as amended, or
by-laws, as amended, of the Company certified by the Company as in effect on the
date of the opinion (collectively, the "Charter Documents") or any Applicable
Law.(2)

                                  Exhibit B-1


                                                                       EXHIBIT C

            Opinion of special regulatory counsel for the Issuers to be
delivered pursuant to Section 5(d) of the Purchase Agreement:

            Based upon and subject to the limitations, qualifications,
exceptions and assumptions set forth herein, we are of the opinion that that the
legal statements in the Health Regulatory Sections of the Offering Memorandum,
insofar as such statements constitute overviews or summaries of the laws and
regulations referred to therein, including the qualifications set forth therein,
fairly present and summarize, in all material respects such laws and regulations
referred to therein. In addition, no facts have come to our attention that lead
us to believe that the Health Regulatory Sections of the Offering Memorandum
with respect to the federal and state health care regulatory matters set forth
therein, as of the date thereof and hereof, contained or contain any untrue
statement of a material fact or omitted or omit to state a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading. As to all
questions of fact material to the opinions contained herein, we have relied,
without independent verification and without any duty of inquiry, upon: (i)
certain documents prepared and furnished to us by representatives of the Issuers
and the Guarantors; (ii) teleconferences and meetings with representatives of
the Issuers and the Guarantors and the representations of facts made by such
parties; and (iii) representations and warranties made in the Transaction
Documents and the accuracy and completeness thereof.

                                                                       EXHIBIT D
                           [Form of Joinder Agreement]

                                JOINDER AGREEMENT

                                                                       EXHIBIT D

                                       By: _____________________________________
                                           Name:
                                           Title:

                                       2


                                                                         ANNEX I

            Resale Pursuant to Regulation S or Rule 144A. Each Initial Purchaser
understands that:

            Such Initial Purchaser agrees that it has not offered or sold and
will not offer or sell the Securities in the United States or to, or for the
benefit or account of, a U.S. Person (other than a distributor), in each case,
as defined in Rule 902 of Regulation S (i) as part of its distribution at any
time and (ii) otherwise until 40 days after the later of the commencement of the
offering of the Securities pursuant hereto and the Closing Date, other than in
accordance with Regulation S or another exemption from the registration
requirements of the Securities Act. Such Initial Purchaser agrees that, during
such 40-day restricted period, it will not cause any advertisement with respect
to the Securities (including any "tombstone" advertisement) to be published in
any newspaper or periodical or posted in any public place and will not issue any
circular relating to the Securities, except such advertisements as permitted by
and include the statements required by Regulation S.

            Such Initial Purchaser agrees that, at or prior to confirmation of a
sale of Securities by it to any distributor, dealer or person receiving a
selling concession, fee or other remuneration during the 40-day restricted
period referred to in Rule 903 of Regulation S, it will send to such
distributor, dealer or person receiving a selling concession, fee or other
remuneration a confirmation or notice to substantially the following effect:

            "The Securities covered hereby have not been registered under the
            U.S. Securities Act of 1933, as amended (the "Securities Act"), and
            may not be offered and sold within the United States or to, or for
            the account or benefit of, U.S. persons (i) as part of your
            distribution at any time or (ii) otherwise until 40 days after the
            later of the date the Securities were first offered to persons other
            than distributors in reliance on Regulation S and the Closing Date,
            except in either case in accordance with Regulation S under the
            Securities Act (or in accordance with Rule 144A under the Securities
            Act or to accredited investors in transactions that are exempt from
            the registration requirements of the Securities Act), and in
            connection with any subsequent sale by you of the Securities covered
            hereby in reliance on Regulation S under the Securities Act during
            the period referred to above to any distributor, dealer or person
            receiving a selling concession, fee or other remuneration, you must
            deliver a notice to substantially the foregoing effect. Terms used
            above have the meanings assigned to them in Regulation S under the
            Securities Act."

            Such Initial Purchaser agrees that the Securities offered and sold
in reliance on Regulation S will be represented upon issuance by a global
security that may not be exchanged for definitive securities until the
expiration of the 40-day restricted period referred to in Rule 903 of Regulation
S and only upon certification of beneficial ownership of such Securities by
non-U.S. persons or U.S. persons who purchased such Securities in transactions
that were exempt from the registration requirements of the Securities Act.
