                            STOCK PURCHASE AGREEMENT

            This STOCK PURCHASE AGREEMENT (this "Agreement"), dated as of
December 6, 2004, is by and among Laidlaw International, Inc., a Delaware
corporation ("Parent"), Laidlaw Medical Holdings, Inc., a Delaware corporation
("Seller") and EMSC, Inc., a Delaware corporation ("Purchaser").

                                    RECITALS

            WHEREAS, Seller owns all of the issued and outstanding shares of
common stock, no par value per share (the "Shares"), of EmCare Holdings Inc., a
Delaware corporation (the "Acquired Company");

            WHEREAS, Seller desires to sell, and Purchaser desires to purchase,
all of the Seller's right, title and interest in and to the Shares on the terms
and conditions contained herein (the "Share Purchase").

            NOW, THEREFORE, the parties agree as follows:

                                   ARTICLE I.
                                PURCHASE AND SALE

            1.01 Purchase and Sale of Shares. Upon the terms and conditions of
this Agreement, at the Closing, Seller shall sell, transfer, convey, assign and
deliver to Purchaser, and Purchaser shall purchase, acquire and accept from
Seller, all of Seller's right, title and interest in and to the Shares.

            1.02 Purchase Price. Subject to the terms and conditions of this
Agreement, on the Closing Date, Purchaser shall pay Seller, by wire transfer of
immediately available funds, an amount equal to $253,000,000 (the "Purchase
Price"). This Purchase Price shall be subject to adjustment pursuant to Section
1.05 following the Closing.

            1.03 Closing. The closing of the Share Purchase (the "Closing") will
take place at 10:00 a.m. local time on the fifth Business Day after satisfaction
or waiver (as permitted by this Agreement and applicable Law) by the appropriate
party of the conditions (excluding conditions that, by their terms, cannot be
satisfied until the Closing Date, but subject to the fulfillment or waiver of
those conditions) set forth in Article VI (the "Closing Date"), unless another
time or date is agreed to in writing by the parties hereto; provided, however,
Purchaser shall not be obligated to consummate the Contemplated Transactions
prior to the Outside Date if Purchaser would be obligated to draw down the
Bridge Facility (as defined in the BofA Financing Commitment) or similar bridge
financing under a Substitute Financing Commitment rather than issue and sell
Senior Subordinated Notes (as defined in the BofA Financing Commitment) or
similar securities contemplated by a Substitute Financing Commitment to complete
the financing contemplated by Section 4.08; provided, further, that Purchaser
shall be obligated to consummate the Contemplated Transactions no later than the
Closing Date if all of the conditions set forth in Section 6.02 (including,
Section 6.02(p)) have been satisfied or



waived. The Closing shall be held at the offices of Kaye Scholer LLP, 425 Park
Avenue, New York, New York 10022, unless another place is agreed to in writing
by the parties hereto.

            1.04 Deliveries. At the Closing:

                  (a) Seller shall deliver, or cause to be delivered, to
Purchaser, the certificates evidencing the Shares;

                  (b) Purchaser shall deliver the Purchase Price to Seller; and

                  (c) The parties shall deliver such other certificates,
instruments or documents as required by Article VI or any other provision of
this Agreement.

            1.05 Post-Closing Adjustment.

                  (a) Within forty-five (45) days after the Closing Date, Seller
shall prepare and deliver to Purchaser (i) an unaudited consolidated balance
sheet of the Acquired Company and the Subsidiaries dated as of the close of
business on the Closing Date (the "Closing Balance Sheet") showing the Net Worth
of the Acquired Company and the Subsidiaries at the Closing Date (the
"Preliminary Net Worth Amount") and (ii) a schedule (the "Closing Debt
Schedule") of the amount of Long Term Debt at the Closing Date (the "Preliminary
Debt Amount"). The Closing Balance Sheet shall be prepared in accordance with
the definitions and procedures set forth on the Post-Closing Adjustment
Schedule. In connection with the preparation of the Closing Balance Sheet and
the Closing Debt Schedule, Purchaser shall give, and shall cause the Acquired
Company and its representatives to give, to Seller and its representatives full
access at all reasonable times to the books, records and other materials of the
Acquired Company and the Subsidiaries and the personnel of, and work papers
prepared by or for Purchaser, the Acquired Company and the Subsidiaries or their
respective accountants, including, without limitation, to such historical
financial information relating to the Acquired Company and the Subsidiaries as
Seller may reasonably request in order to permit the timely preparation and
delivery of the Closing Balance Sheet and the Closing Debt Schedule in
accordance with this Section 1.05(a).

                  (b) Upon receipt of the Closing Balance Sheet and the Closing
Debt Schedule, Purchaser shall have thirty (30) days (the "Review Period") to
review such Closing Balance Sheet and the Closing Debt Schedule and related
computations of the Net Worth of the Acquired Company and the Subsidiaries and
the Closing Debt on the Closing Date. If Purchaser has accepted such Closing
Balance Sheet Closing Debt Schedule in writing or has not given written notice
to Seller setting forth in reasonable detail any objection of Purchaser to such
Closing Balance Sheet or Closing Debt Schedule(a "Statement of Objections")
prior to the expiration of the Review Period, then such Closing Balance Sheet
and Closing Debt Schedule shall be final and binding upon the parties, and the
Preliminary Net Worth Amount shall be deemed the Net Worth amount of the
Acquired Company and the Subsidiaries as of the Closing Date (the "Final Net
Worth Amount") and the Preliminary Debt Amount shall be deemed to be the amount
of Long Term Debt as of the Closing Date (the "Final Debt Amount"). In addition,
to the extent any portion of the Closing Balance Sheet or of the calculation of
the Preliminary Net Worth Amount, of the Closing Debt Schedule or of the
calculation of the Preliminary Debt

                                        2


Amount shall not be expressly objected to in the Statement of Objections, such
matters shall be deemed to have been accepted and approved by Purchaser and
shall be final and binding upon the parties for purposes hereof. In the event
that Purchaser delivers a Statement of Objections during the Review Period,
Purchaser and Seller shall use their commercially reasonable efforts to agree on
the amount of Net Worth of the Acquired Company and the Subsidiaries on the
Closing Date within thirty (30) days following the receipt by Seller of the
Statement of Objections. If the parties are unable to reach an agreement as to
such amounts within such thirty (30) day period, then the matter shall be
submitted to Deloitte & Touche LLP, or such other accountant as shall be
mutually agreed between the parties hereto (such accountant, the "Settlement
Accountant"), who shall determine the matters still in dispute and adjust the
Closing Balance Sheet to reflect such determination and establish the Final Net
Worth Amount and adjust the Closing Debt Schedule and establish the Final Debt
Amount. If issues in dispute are submitted to the Settlement Accountant for
resolution, each party will furnish to the Settlement Accountant such work
papers and other documents and information relating to the disputed issues as
the Settlement Accountant may request, and will be afforded the opportunity to
present to the Settlement Accountant any material relating to the resolution of
the disputed items and to discuss the resolution of the disputed items with the
Settlement Accountant; provided, that no party shall have any ex parte
discussions with the Settlement Accountant (other than after reasonable notice
to the other party and such party's refusal or failure to participate). The
Settlement Accountant will be instructed in performing the review that Purchaser
and Seller will each be provided with copies of any and all correspondence and
drafts distributed to any party, and Purchaser and Seller will be granted access
to information contained in the documents made available to the Settlement
Accountant by the other party. The Settlement Accountant shall determine only
those matters in dispute (and based solely on the materials and other
information presented by Seller and Purchaser and not by independent
investigation). The Settlement Accountant shall make its determination within
thirty (30) days (or as soon as practicable thereafter if the Settlement
Accountant notifies the parties that it requires additional time to make such
determination) following the submission of the matter to the Settlement
Accountant for resolution, and such determination shall be final and binding
upon Purchaser and Seller. Purchaser and Seller will each bear fifty percent
(50%) of the fees, charges and expenses of the Settlement Accountant.

                  (c) In the event that the Final Net Worth Amount is greater
than the Target Net Worth Amount, such excess is referred to herein as the
"Excess Net Worth Amount".

                  (d) In the event that the Final Net Worth Amount is less than
the Target Net Worth Amount, such deficiency is referred to herein as the "Net
Worth Deficiency".

                  (e) Calculation of Payments.

                        (i) If there is an Excess Net Worth Amount and an AMR
Excess Net Worth Amount, and such amounts in the aggregate are equal to or less
than $20,000,000, then Purchaser shall be obligated to pay to Seller the Excess
Net Worth Amount.

                        (ii) If there is an Excess Net Worth Amount and an AMR
Excess Net Worth Amount, and such amounts in the aggregate are greater than
$20,000,000, then Purchaser shall be obligated to pay to Seller an amount equal
to $20,000,000 multiplied by a

                                        3


fraction, of which the numerator is the Excess Net Worth Amount and the
denominator is the sum of the Excess Net Worth Amount plus the AMR Excess Net
Worth Amount.

                        (iii) If there is an Excess Net Worth Amount and an AMR
Net Worth Deficiency, then Purchaser shall be obligated to pay to Seller an
amount equal to the lesser of (A) the Excess Net Worth Amount and (B) the sum of
the AMR Deficiency plus $20,000,000.

                        (iv) If there is a Net Worth Deficiency, Seller shall be
obligated to pay to Purchaser an amount equal to the Net Worth Deficiency.

                        (v) If there is an Excess Net Worth Amount and there is
neither an AMR Excess Net Worth Amount nor an AMR Net Worth Deficiency, then
Purchaser shall be obligated to pay to Seller an amount equal to the lesser of
the Excess Net Worth Amount and $20,000,000.

                  (f) Any amounts payable by Purchaser to Seller pursuant to
Section 1.05(e) shall be paid within five (5) Business Days following the
determination of the Final Net Worth Amount pursuant to Section 1.05(b) and the
"Final Net Worth Amount" pursuant to Section 1.05(b) of the AMR Stock Purchase
Agreement, together with interest thereon for the period from the Closing Date
to (and including) the date of payment, at the prime rate as quoted in the Money
Rates Section of The Wall Street Journal (the "Applicable Rate"), by wire
transfer of immediately available funds to one or more accounts designated by
Seller.

                  (g) Any amounts payable by Seller to Purchaser pursuant to
Section 1.05(e) shall be paid within five (5) Business Days following the
determination of the Final Net Worth Amount pursuant to Section 1.05(b) and the
"Final Net Worth Amount" pursuant to Section 1.05(b) of the AMR Stock Purchase
Agreement, together with interest thereon for the period from the Closing Date
to (and including) the date of payment, at the Applicable Rate, by wire transfer
of immediately available funds to one or more accounts designated by Purchaser.

                  (h) Any amounts payable pursuant to Sections 1.05(f) or (g)
shall be deemed to increase or decrease the Purchase Price, as applicable.

                  (i) In the event that the Final Debt Amount is greater than
zero (such excess, the "Excess Debt Amount"), the Purchase Price shall be
decreased by, and Seller shall pay to Purchaser, within five (5) Business Days
following the determination of the Final Debt Amount pursuant to Section
1.05(b), an amount equal to such Excess Debt Amount, together with interest
thereon for the period from the Closing Date to (and including) the date of
payment, at the Applicable Rate, by wire transfer of immediately available funds
to one or more accounts designated by Purchaser.

                                  ARTICLE II.
               REPRESENTATIONS AND WARRANTIES OF SELLER AND PARENT

            Each of Seller and Parent, as applicable, represents and warrants to
Purchaser that the statements contained in this Article II are true and correct,
except as set forth in the schedules provided by Seller and Parent to Purchaser
dated the date hereof (the "Disclosure Schedules").

                                        4


Each disclosure set forth in the Disclosure Schedules is identified by reference
to, or has been grouped under a heading referring to, a specific individual
section of this Agreement and disclosure made pursuant to any section thereof
shall be deemed to be disclosed on each of the other sections of the Disclosure
Schedules to the extent the applicability of the disclosure to such other
section is reasonably apparent from the disclosure made; provided, that, except
as otherwise provided in this Agreement, Seller shall not be required to
identify or refer to specific individual subsections of this Agreement in the
Disclosure Schedules. The inclusion of any information in the Disclosure
Schedules (or any update thereto) shall not be deemed to be an admission or
acknowledgment, in and of itself, that such information is required by the terms
hereof to be disclosed, is material to the Business, has resulted in or would
result in a Material Adverse Effect or is outside the ordinary course of
business.

            2.01 Ownership of Shares. Seller is the record and beneficial owner
of all of the Shares free and clear of all Encumbrances, other than Encumbrances
pursuant to the Senior Secured Credit Facility, the PBGC Settlement Agreement or
this Agreement. The sale of the Shares to Purchaser pursuant to Article I will
be effective to transfer title to all of the Shares to Purchaser free and clear
of any Encumbrances.

            2.02 Organization. Each of Seller and Parent is a corporation duly

                        REPRESENTATIONS AND WARRANTIES OF
                     SELLER RELATING TO THE ACQUIRED COMPANY

            Seller represents and warrants to Purchaser that the statements
contained in this Article III are true and correct, except as set forth in the
Disclosure Schedules. Each disclosure set forth in the Disclosure Schedules is
identified by reference to, or has been grouped under a heading referring to, a
specific individual section of this Agreement and disclosure made pursuant to
any section thereof shall be deemed to be disclosed on each of the other
sections of the Disclosure Schedules to the extent the applicability of the
disclosure to such other section is reasonably apparent from the disclosure
made; provided, that, except as otherwise provided in this Agreement, Seller
shall not be required to identify or refer to specific individual subsections of
this Agreement in the Disclosure Schedules. The inclusion of any information in
the Disclosure Schedules (or any update thereto) shall not be deemed to be an
admission or acknowledgment, in and of itself, that such information is required
by the terms hereof to be disclosed, is material to the Business, has resulted
in or would result in a Material Adverse Effect or is outside the ordinary
course of business.

            3.01 Organization. The Acquired Company is a corporation duly
organized, validly existing and in good standing under the laws of Delaware and
has all requisite corporate power and authority to own, lease and operate the
Assets and the Business and to carry on the Business as it is now being
conducted. The Acquired Company is duly qualified to do business and is in good
standing as a foreign corporation in each jurisdiction in which the nature of
its business or the ownership, lease or operation of its Assets makes such
qualification necessary, except where the failure to have such power or
authority, to be in good standing or to be duly qualified to transact business,
would not result in material monetary costs to Purchaser or a forfeiture of
material rights by Purchaser.

            3.02 Capitalization. The authorized capital of the Acquired Company
consists solely of 1,500 shares of common stock, no par value per share, of
which 1,031 shares are issued and outstanding and constitute the Shares. Seller
is the record and beneficial owner of the Shares, free and clear of all
Encumbrances, other than Encumbrances pursuant to the Senior Secured Credit
Facility, the PBGC Settlement Agreement or this Agreement. The Shares have been
duly authorized, validly issued and are fully paid, non-assessable and free of
preemptive rights. Except for this Agreement and the Contemplated Transactions
and except as set forth on the Capitalization Schedule, there are no outstanding
options, warrants, purchase rights, subscription rights, conversion rights,
exchange rights, or other Contracts with respect to the Shares or that could
require the Acquired Company to issue, sell or otherwise cause to become
outstanding any common stock or other equity securities or other securities of
the Acquired Company. Except as set forth on the Capitalization Schedule, there
are no outstanding or

                                        6


authorized stock appreciation, phantom stock, profit participation, or similar
rights with respect to the Acquired Company. Except pursuant to this Agreement,
no equity securities of the Acquired Company are subject to any agreements or
understandings between or among any Persons with respect to the voting or
transfer thereof. The Acquired Company does not have outstanding any bonds,
debentures, notes or other obligations the holders of which have the right to
vote (or are convertible into or exercisable for securities having the right to
vote) on any matter.

            3.03 Subsidiaries.

                  (a) The Subsidiaries Schedule sets forth a true and complete
list of the subsidiaries of the Acquired Company (each, a "Subsidiary" and
collectively, the "Subsidiaries"), including the jurisdiction of incorporation,
organization or formation of each such Subsidiary, the jurisdictions in which
any such Subsidiary is qualified to do business as a foreign entity, and the
authorized (if applicable) and outstanding stock of each such Subsidiary and the
record owners of the issued capital of each Subsidiary. Except as set forth on
the Subsidiaries Schedule, the Acquired Company is the beneficial owner,
directly or indirectly, of all of the equity securities of each Subsidiary
(other than any Affiliated Medical Group or any Billing Partnership).

                  (b) Each Subsidiary (i) has been duly organized and is validly
existing and in good standing under the laws of the jurisdiction of its
incorporation or organization, (ii) has all necessary corporate, partnership,
limited liability company or other power and authority to own, lease and operate
its Assets and the Business and to carry on the Business as currently conducted
by it and (iii) is duly qualified to do business and is in good standing in each
jurisdiction in which the nature of its business and ownership, lease or
operation of its Assets makes such qualification necessary, except where the
failure to have such power or authority, to be in good standing or to be duly
qualified to transact business, would not result in material monetary costs to
Purchaser or a forfeiture of material rights by Purchaser, and as set forth with
respect to each such Subsidiary on the Subsidiaries Schedule.

                  (c) All of the outstanding equity securities of each such
Subsidiary (i) where the Subsidiary is a corporation, are duly and validly
issued, fully paid and non-assessable, (ii) where the Subsidiary is not a
corporation, are duly created pursuant to the laws of the jurisdiction of such
Subsidiary's organization or formation, issued and paid for in accordance with
such Subsidiary's Organizational Documents and are fully paid and non-assessable
and (iii) are held of record by the Person or Persons set forth on the
Subsidiaries Schedule. Except as set forth on the Subsidiaries Schedule, the
Acquired Company owns, directly or indirectly through another Subsidiary, all of
the equity securities and other securities in each Subsidiary, free and clear of
all Encumbrances, other than Encumbrances pursuant to the Senior Secured Credit
Facility, the PBGC Settlement Agreement or this Agreement. Except as set forth
on the Subsidiaries Schedule, neither the Acquired Company nor any Subsidiary
owns, or has any right to acquire, any equity securities or other securities of
any Person (other than, in the case of the Acquired Company and each Subsidiary,
a Subsidiary) or any direct or indirect equity interest in any other Person.
Except as set forth in the applicable Organizational Documents of each
Subsidiary, there are no options, warrants or rights of conversion or any other
Contract relating to any Subsidiary obligating such Subsidiary, directly or
indirectly, to issue additional equity securities or other securities in such
Subsidiary. Except as set forth on the Subsidiaries Schedule,

                                        7


no Person has the right to cause the redemption or repurchase of any equity
securities or other securities of any Subsidiary, nor are any equity securities
or other securities of any Subsidiary subject to, any Contracts or
understandings between or among any Persons with respect to the voting or
transfer thereof. No Subsidiary has outstanding bonds, debentures, notes or
other obligations the holders of which have the right to vote (or are
convertible into or exchangeable for securities having the right to vote) on any
matter. Each Affiliated Medical Group is owned, directly or indirectly, by a
Medical Professional with whom the Acquired Company or a Subsidiary has entered
into a Contract of the type required to be disclosed pursuant to Section
3.15(a)(x).

            3.04 No Violations. The execution and delivery by Seller of this

right, or the imposition or material modification of any material obligation, of
the Acquired Company or any Subsidiary under any Scheduled Contract; (c) subject
to obtaining the Required Consents, violate or result in a breach of or
constitute a default under any Law or Order; or (d) result in the creation or

a Permitted Lien).

            3.05 Consents and Approvals. Except for any Consent required under

Acquired Company or any Subsidiary, (b) no Consent is required by any applicable
Law or other binding action or requirement of an Authority, and (c) no Consent

to perform their respective obligations hereunder and thereunder and to perform

acceleration (whether after the giving or notice or the lapse of time or both)
of, or cause the loss or material modification of any right, or the imposition
or material modification of any material obligation, of the Acquired Company or
any Subsidiary under any Lease. Neither the Acquired Company nor any Subsidiary

communication regarding any actual or possible (i) termination, cancellation or
invalidation of any of Policy or (ii) refusal of any coverage or rejection of
any material claims under any Policy, or (iii) any retroactive, retrospective or
other premium adjustments under any Policy.

affect the operation or conduct of the Business or the use of the Assets in any
jurisdiction where the Acquired Company or any Subsidiary conducts material
business or, unless involving any medical malpractice claim or other claim
covered by any Policy (but only to the extent of such coverage), if determined
adversely, would reasonably be expected to result in Damages to the Acquired
Company or any Subsidiary in excess of $2,000,000, or (b) would reasonably be
expected to prevent or materially delay the performance of this Agreement by
Seller. Except as set forth on the Litigation Schedule, there are no judgments

of the Acquired Company and the Subsidiaries, taken as a whole, or to the
operation or conduct of the Business or the use of the Assets in any
jurisdiction where the Acquired Company or any Subsidiary conducts material
business. This Section 3.11(a) shall not apply to compliance matters which are
the subject of Sections 3.13, 3.18, 3.19 and 3.22.

                  (b) The Acquired Company and each Subsidiary is, and at all
times since the issuance of any Order to which the Acquired Company, any

                  (a) The Acquired Company and the Subsidiaries possess all
Governmental Authorizations that are required by any Governmental Authority to
conduct the Business as presently conducted by the Acquired Company and the
Subsidiaries, except for each such Governmental Authorization the failure of
which to obtain, individually or in the aggregate, has not had and would not
reasonably be expected to have, individually or in the aggregate, a Material
Adverse Effect. Each Governmental Authorization is valid and in full force and
effect. The Acquired Company and each Subsidiary is in compliance with all
applicable terms and requirements of each Governmental Authorization, except for
any such non-compliance that, individually or in the aggregate, has not had and
is not reasonably expected to have a Material Adverse Effect. To the Knowledge
of Seller, there is no threatened suspension, cancellation or termination of any
Governmental Authorization that is reasonably expected to have a Material
Adverse Effect.

                  (b) Except as would not, individually or in the aggregate,

financial condition or results of operations of the Acquired Company and the
Subsidiaries, taken as a whole, to the extent required under applicable Law, the

property leased by the Acquired Company or any Subsidiary. To the Knowledge of

manner that would not reasonably be expected to result in the need for material
remediation under Environmental Laws. There are no pending or, to the Knowledge
of Seller, threatened Actions against the Acquired Company or any of the
Subsidiaries arising from or relating to any Environmental Conditions. There has
been no release of a Hazardous Substance at a real property formerly leased or

material Liability under Environmental Laws to the Acquired Company or any
Subsidiary.

delivery and performance of this Agreement by Purchaser has been, and the Other
Purchaser Documents will be, duly and validly authorized by all necessary action
of Purchaser and its Affiliates and no additional authorization on the part of
Purchaser is necessary in connection with the execution, delivery and
performance of this Agreement. This Agreement has been, and the Other Purchaser
Documents will be, duly executed and delivered by Purchaser. This Agreement is,
and the Other Purchaser Documents will be, a legal, valid and binding obligation
of Purchaser, enforceable against Purchaser in accordance with its terms,
subject to applicable bankruptcy, insolvency, reorganization, moratorium and
similar laws affecting creditors' rights and remedies generally and to general
principles of equity.

            4.03 No Violations. The execution and delivery by Purchaser of this
Agreement do not, and the performance and consummation of the Contemplated
Transactions will not: (a) conflict with or violate any provision of the
Organizational Documents of Purchaser; (b) conflict with, or result in the
breach of, or constitute a default under, or result in the termination,
cancellation or acceleration (whether after the giving of notice or the lapse of
time or both) of any right or obligation of Purchaser under, any contract or
agreement to which Purchaser is party or to which any of its assets is subject;
or (C) violate or result in a breach of or constitute a default under any Law or
Order applicable to Purchaser or by which Purchaser or any of its assets is
bound or affected, except, in the cases of clauses (b) and (c), for any
conflict, breach, default, termination, cancellation, acceleration, loss or
violation which, individually or in the aggregate, would not materially impair
Purchaser's ability to effect the Closing.

            4.04 Consents and Approvals. Except for any Consent required under
the HSR Act, no Consent is required to be obtained by Purchaser or any Affiliate
from, and no notice or filing is required to be given by Purchaser or any
Affiliate to or made by Purchaser or any Affiliate with, any Authority or other
Person in connection with the execution, delivery and performance by Purchaser
of this Agreement, other than in all cases where the failure to obtain such
Consent or to give or make such notice or filing would not, individually or in
the aggregate, materially impair Purchaser's ability to effect the Closing.

            4.05 Brokers and Finders. No investment banker, broker, finder or
other intermediary (a) has acted for or on behalf of Purchaser in connection
with this Agreement or the

Contemplated Transactions or (b) is entitled to any fee or commission from
Purchaser in connection with this Agreement or the Contemplated Transactions.

            4.06 Absence of Proceedings. There are no lawsuits, actions, or
administrative or other proceedings pending nor, to the Knowledge of Purchaser,
are any such proceedings threatened or any governmental investigations pending,
against Purchaser that would reasonably be expected to restrict Purchaser's
ability to consummate the transactions contemplated in this Agreement.

            4.07 Investment Intent. Purchaser has such knowledge and experience
in financial matters that it is capable of evaluating the merits and risks of
its purchase of the Shares. Purchaser has been provided the opportunity to ask
questions of the officers and management employees of Seller and the Acquired
Company and the Subsidiaries and to acquire additional information about the
business and financial condition of the Acquired Company and the Subsidiaries.
Purchaser is acquiring the Shares for investment and not with a view toward or
for sale in connection with any distribution thereof, or with any present
intention of distributing or selling the Shares. Purchaser acknowledges that the
Shares may not be sold, transferred, offered for sale, pledged, hypothecated or
otherwise disposed of without registration under the Securities Act, except
pursuant to an exemption from such registration available under the Securities
Act, and without compliance with foreign securities laws in each case, to the
extent applicable. Nothing in this Section 4.07 will preclude Purchaser from
relying on the representations, warranties, covenants and agreements of Seller
herein or from pursuing its remedies with respect to a breach thereof.

            4.08 Financing. Purchaser has delivered to Seller a true and
complete copy of (a) a fully executed commitment letter from Banc of America
Securities LLC, Banc of America Bridge LLC, Bank of America, N.A., JPMorgan
Chase Bank, N.A. and J.P. Morgan Securities Inc. (the "Lenders") whereby such
Lenders have committed, upon the terms and conditions set forth therein, to
provide senior debt financing in an amount of $700,000,000 in connection with
the Contemplated Transactions (the "BofA Financing Commitment"), and (b) a fully
executed commitment letter from Onex Partners L.P. whereby Onex Partners L.P.
has committed (the "Onex Equity Commitment"), on the terms and subject to the
conditions set forth therein, to provide equity financing in the aggregate
amount of $215,000,000 in connection with the Contemplated Transactions. As of
the date hereof, each of the BofA Financing Commitment and the Onex Equity
Commitment has not been amended or modified and is in full force and effect.
Purchaser is not aware of any fact which would cause it to believe (i) that the
debt financing contemplated by the BofA Financing Commitment will not be
available to Purchaser as contemplated therein, subject to the conditions set
forth in such BofA Financing Commitment; or (ii) that the equity financing
contemplated by the Onex Equity Commitment will not be consummated as
contemplated therein, subject to the conditions set forth in such Onex Financing
Commitment.

            4.09 Representations and Warranties. Purchaser acknowledges that the
representations and warranties set forth in Article II and Article III,
including the related Disclosure Schedules, constitute the sole and exclusive
representations and warranties of Seller to Purchaser in connection with the
Contemplated Transactions, and Purchaser acknowledges and agrees that Seller is
not making any representation or warranty whatsoever, express or

                                       24


implied, including any implied warranty as to condition, merchantability, or
suitability as to any of the Assets of the Acquired Company and the Subsidiaries
beyond those expressly given in this Agreement, and it is understood that
Purchaser takes such Assets and the Assets related thereto as is and where is
(subject to the benefit of the representations and warranties set forth in this
Agreement). Purchaser further acknowledges and agrees that any estimates,
projections, forecasts or other predictions that may have been provided to
Purchaser or any of its employees, agents or representatives are not
representations or warranties of Seller or its Affiliates.

                                   ARTICLE V.

                  (a) Seller will (i) cause the Acquired Company and the
Subsidiaries to permit representatives of the Purchaser to have reasonable
access during normal business hours, and in a manner so as not to interfere with
the normal business operations of the Acquired Company and the Subsidiaries, to
all premises, properties, personnel, books, records (including Tax records and
accountants' work papers), Contracts and documents of or pertaining to the
Acquired Company or any Subsidiary; (ii) furnish Purchaser and its advisors with
copies of all such Contracts, books and records, and other existing documents
and data as Purchaser may reasonably request, (iii) furnish Purchaser and its
advisors with such additional existing financial, operating and other data and
information as Purchaser may reasonably request, and (iv) make available to
Purchaser and its advisors, upon reasonable advance notice and during normal

Acquired Company or any Subsidiary, as Purchaser may reasonably request. The
confidentiality of all such documents and information furnished in connection
with the Contemplated Transactions shall be governed by the terms of the
Confidentiality Agreement.

                  (b) Purchaser agrees (i) to hold all of the books and records
of the Acquired Company and the Subsidiaries (other than books and records
relating to Tax matters, the retention of which shall be governed by Section
5.10(b) hereof) existing and in possession of the Acquired Company or the
Subsidiaries on the Closing Date, not to destroy or dispose of any such books or
records except in accordance with the Acquired Company's general document
retention policies (copies of which policies will be provided to Seller upon
request), and prior to the destruction or disposal of any such books and
records, to surrender them to Seller (or its successors or assigns) or to allow
Seller (or its successors or assigns) to make copies of such books and records,
and (ii) following the Closing Date, to afford Seller (or its successors or
assigns), its accountants, representatives and counsel, during normal business

such books, records and other data and to the employees of Purchaser and the
Acquired Company and the Subsidiaries at no cost to Seller (other than for
reasonable out-of-pocket expenses of Purchaser, the Acquired Company or the
Subsidiaries in providing such books, records and employees) to the extent that
such access may be requested for any legitimate business purpose.
Notwithstanding the foregoing, books and records relevant to a Proceeding
between a Purchaser or Seller shall be subject to production only in accordance
with the discovery procedures relating to such Proceeding.

                                       28


                  (c) From and after the Closing, and subject to the
requirements of applicable Law, any securities exchange on which the securities
of Seller or its Affiliates are listed or any Third-Party Claim or Direct Claim,
Seller and Parent shall keep secret and retain in confidence, and not use for
the benefit of Seller, Parent or any Person other than Purchaser, all
confidential matters and trade secrets known to Seller or Parent relating to the
Business, including all books and records referred to in Section 5.02(b) and
information made available to Seller pursuant to Section 1.05(a).

            5.03 Consents and Approvals.

                  (a) Upon the terms and subject to the conditions of this
Agreement, Seller and Purchaser will cooperate and use commercially reasonable
efforts to fulfill the conditions precedent to the other parties' obligations
under this Agreement, including securing as promptly as practicable all Required
Consents; provided, that Seller shall not be required to make any payment to any
third party to secure any such Required Consents and Purchaser shall not be
required to agree to any significant amendment to or modification of any
Scheduled Contract or any Permit. Without limiting the foregoing, the parties to
this Agreement shall cooperate with one another: (i) in the prompt preparation
and filing of any filings required under the HSR Act (which filing shall occur
no later than 10 days after the date of this Agreement), if any, and any other
required filings with any Governmental Authority, and the parties shall
cooperate with each other in connection with the making of all such filings,
including providing copies of all such documents to the non-filing party and its
advisors prior to filing and, if requested, to accept all reasonable additions,
deletions or changes suggested in connection therewith; (ii) in determining
whether action by or in respect of, or filing with, any Governmental Authority
is required, proper or advisable or any actions or Consents are required to be
obtained from parties to any Contracts, in connection with the Contemplated
Transactions; and (iii) in seeking timely to obtain any such actions or Consents
or to make any such filings. In case at any time after the Closing any further
action is necessary or desirable to carry out the purposes of this Agreement,
the proper officers and directors of each party to this Agreement shall take all
such necessary action according to Section 10.02.

                  (b) Seller and Purchaser agree to use their commercially
reasonable efforts (including, without limitation, the actions specified in this
Section 5.03(b)) to resolve such objections, if any, as may be asserted with
respect to the Contemplated Transactions under the HSR Act or any other
antitrust Law. In furtherance and not in limitation of the foregoing, Purchaser
agrees to take such commercially reasonable action as may be required by any
domestic court or similar tribunal in any suit brought or threatened by a
Governmental Authority or brought or threatened by a private party challenging
the Contemplated Transactions contemplated hereby as violative of the HSR Act or
any other antitrust Law to avoid the entry of, or to effect the dissolution,
modification or suspension of, any injunction, temporary restraining order or
other Order that has the effect of preventing or delaying the consummation of
the Contemplated Transaction (including the appeal thereof, provided, that,
Purchaser shall not be required to post any bond); provided, that, Purchaser
shall not be required to sell or otherwise dispose of, or hold separate and
agree to sell or otherwise dispose of any Assets or businesses of the Acquired
Company and the Subsidiaries.

                                       29


                  (c) All filing fees required in connection with any filings
under the HSR Act or with any other Governmental Authority shall be borne by
Purchaser. All other fees, expenses and disbursements incurred in connection
with the matters referred to in this Section 5.03 hereof shall be borne by
Purchaser if incurred by or on its behalf and by Seller if incurred by or on
behalf of Seller, the Acquired Company or any Subsidiary.

                  (d) If the Acquired Company or any Subsidiary has not obtained
by Closing any of the Required Consents in connection with a direct or indirect
change in ownership resulting from the Contemplated Transactions, then, to the
extent reasonably practicable (and without material cost or liability to
Seller), the parties shall use commercially reasonable efforts to enter into an
alternative, lawful arrangement under which Purchaser shall have the benefit
from and after Closing of such Contract or Permit for which the Required Consent
was not able to be obtained prior to Closing. For the avoidance of doubt, the
provisions of this Section 5.03(d) shall not supersede the provisions of Section
6.02(i).

            5.04 Public Announcements. Prior to Closing, the parties hereto will
use commercially reasonable efforts to consult with each other before issuing
any press release or otherwise making any public statements with respect to this
Agreement or the Contemplated Transactions (unless such consultation is not
possible due to the requirements of applicable Law or any securities exchange on
which the securities of the parties or their Affiliates or a related Person are
listed) and, except as may be required by applicable Law or any securities
exchange on which the securities of the parties or their Affiliates or a related
Person are listed, none of the parties shall issue any such press release or
make any such public statement without the prior approval of (a) in the case of
announcement by Purchaser (or its Affiliates or related persons) by Seller or
Parent and (b) in the case of announcement by Seller or Parent, by Purchaser,
such approval not to be unreasonably withheld, conditioned or delayed. The
provisions of this Section 5.04 shall not apply to any public disclosure made by
Parent or any Affiliate or related person or Purchaser pursuant to applicable
Law if the content of such disclosure is consistent with a press release or
other public statement previously made in accordance with the preceding
sentence.

            5.05 Employee Benefits Matters.

                  (a) As of the Closing Date, the Acquired Company Employees on
such date shall continue employment with the Acquired Company or the relevant
Subsidiary in the same positions and at the same level of wages and/or salary
and without having incurred a termination of employment or separation from
service; provided, however, that neither the Acquired Company nor any Subsidiary
shall be obligated to continue any employment relationship with any employee or
maintain any level of wages and/or salary for any specific period of time.
Purchaser agrees that for purposes of all employee benefit plans under which an
employee's benefit depends, in whole or in part, on length of service, credit
will be given to Acquired Company Employees for service previously credited with
the Acquired Company or any Subsidiary prior to the Closing Date, provided, that
such crediting of service does not result in duplication of benefits, and
provided, further, that such crediting of service shall not be given for benefit
accrual purposes under any defined benefit plan.

                  (b) The parties hereto acknowledge and agree that all
provisions contained in this Section 5.05 with respect to the Acquired Company
Employees are included for

                                       30


the sole benefit of the respective parties hereto and shall not create any right
in any other person, including, without limitation, any Acquired Company
Employees, former Acquired Company Employees, or any of their dependents or
beneficiaries.

            5.06 Directors' and Officers' Indemnification; Release from
Liability.

                   (a) The provisions of the Acquired Company's and each
Subsidiary's Organizational Documents concerning the elimination of liability
and indemnification of directors and officers, as in effect on September 1,
2004, shall not be amended in any manner that would adversely affect the rights
thereunder of any Person that is as of the date hereof an officer or director of
the Acquired Company or any Subsidiary. In addition to the foregoing, from and
after the Closing Date, Purchaser and the Acquired Company or the relevant
Subsidiary shall, jointly and severally, and in accordance with applicable Law,
indemnify, hold harmless and defend each Person who is a current or former
officer or director of the Acquired Company or any Subsidiary (the "D&O
Indemnitees") against all Damages or expenses (including reasonable attorneys'
fees) arising out of or pertaining to acts or omissions (or alleged acts or
omissions) of the D&O Indemnitees, or any of them, in their capacities as such.
To the maximum extent permitted by applicable Law, the indemnification and
related rights hereunder shall be mandatory rather than permissive, and
Purchaser and the Acquired Company or the relevant Subsidiary shall promptly
advance expenses in connection with such indemnification to the extent permitted
under applicable Law; provided, that, to the extent required by Law, the Person
to whom expenses are advanced provides an undertaking to repay such advances if
it is ultimately determined that such Person is not entitled to indemnification.

                  (b) For a period of five years from and after the Closing
Date, Purchaser shall cause the Acquired Company and the Subsidiaries to procure
and maintain in effect with respect to all periods prior to the Closing Date,
directors' and officers' liability insurance (or Purchaser shall procure a
"tail" or "extended reporting period" policy) covering those present and former
officers and directors of the Acquired Company and the Subsidiaries who are
currently covered by directors' and officers' liability insurance policies on
terms not materially less favorable in the aggregate than the terms of such
current insurance coverage; provided, however, that if any Claim is asserted or
made within such five-year period, such insurance shall be continued in respect
of such Claim until the final disposition thereof; and, provided, further, that
Purchaser shall only be obligated to maintain such coverage (which shall be in
the form of a single policy which need not exceed $25,000,000, and which shall
cover the present and former officers and directors of the Acquired Company and
the Subsidiaries and American Medical Response, Inc. and its subsidiaries)) as
may be obtained for a cost no greater than $800,000, in the aggregate, with
respect to the coverages contemplated pursuant to this Section 5.06(b) and
Section 5.06(b) of the AMR Stock Purchase Agreement.

                  (c) Effective upon the Closing, Purchaser and the Acquired
Company and the Subsidiaries, and each of their respective representatives,
successors and assigns (collectively, the "Releasing Parties"), shall be deemed
to have remised, released and forever discharged the individuals set forth on
Exhibit 5.06(c) hereto solely in their capacity as directors of the Acquired
Company or any Subsidiary (collectively, the "D&O Released Parties") of and from
any and all Claims which the Releasing Parties, or any of them, now has or ever
had, or hereafter can, shall or may have, for, upon or by reason of any matter,
cause or thing whatsoever,

                                       31


against the D&O Released Parties, and each of them, from the beginning of time
through the Closing Date; provided, however, that this Section 5.06(c) shall not
apply to (i) any Claims that may arise from any breach by any of the D&O
Released Parties of, or the failure to properly perform, any obligation or duty
arising on the part of any of the D&O Released Parties after the date hereof
under this Agreement or any other agreement to be entered into after the date
hereof and contemplated hereby to which any of the D&O Released Parties is a
party; or (ii) any Claims that may arise as a result of any self-dealing or
improper receipt of a personal benefit on the part of any D&O Released Party.

                  (d) The provisions of this Section 5.06 are (i) intended to be
for the benefit of, and shall be enforceable by, each Person released or
entitled to indemnification hereunder, and each such Person's heirs,
representatives, successors or assigns, it being expressly agreed that such
Persons shall be third party beneficiaries of this Section 5.06, and (ii) in
addition to, and not in substitution for, any other right to indemnification or
contribution that any such Person may have by contract or otherwise.

            5.07 Intercompany Accounts. Immediately prior to the Closing, (a)
all intercompany accounts payable owing to Seller or its Affiliates (other than
the Acquired Company or any Subsidiary) by the Acquired Company or any
Subsidiary, and (b) all intercompany accounts payable owing by Seller or its
Affiliates (other than the Acquired Company or any Subsidiary) to the Acquired
Company or any Subsidiary shall be forgiven, discharged, released, cancelled
(including by way of capital contribution) or paid, in each case as determined
by Seller in its sole discretion.

            5.08 Resignations of Directors. Except as otherwise specifically
directed by Purchaser, each director of the Acquired Company or any Subsidiary
as of the Closing Date shall resign as a director of the Acquired Company and
any such Subsidiaries and such resignations shall be delivered to Purchaser at
Closing.

            5.09 Notice of Certain Matters. From the date hereof through the
Closing, Seller and Parent shall give notice to Purchaser of (a) the occurrence,
or failure to occur, after the date hereof of any event which occurrence or
failure would be likely to cause any representation or warranty contained in
this Agreement or in any Exhibit or Schedule hereto to be untrue or inaccurate
in a manner reasonably likely to result in the failure of a condition set forth
in Section 6.02 hereof (a "Representation Breach"), and (b) any failure of
Seller, or of its respective representatives, to comply with or satisfy any
covenant, condition or agreement to be complied with or satisfied by it under
this Agreement or any Exhibit or Schedule hereto in a manner reasonably likely
to result in the failure of a condition set forth in Section 6.02 hereof (a
"Covenant Failure"). In such event, unless this Agreement is terminated pursuant
to Section 7.01(d) hereof prior to the Closing or such Representation Breach or
Covenant Failure (disregarding any qualification as to materiality or Material
Adverse Effect and considered collectively with any other Representation Breach
and Covenant Failure notified or required to be notified under this Section
5.09) would reasonably be expected to result in a Material Adverse Effect, if
the action giving rise to such event is permitted pursuant to Section 5.01
hereof each written notice provided by Seller to Purchaser pursuant to this
Section 5.09 shall be deemed (i) to have amended the applicable Schedule or
Exhibit, (ii) to have qualified the representations and warranties contained in
Article II and Article III hereof, as applicable, and (iii) to have cured any

                                       32


Representation Breach that otherwise might have existed hereunder by reason of
such development. Notwithstanding the foregoing, unless this Agreement is
terminated pursuant to Section 7.01(d) hereof prior to the Closing or such
Representation Breach or Covenant Failure (disregarding any qualification as to
materiality or Material Adverse Effect and considered collectively with any
other Representation Breach and Covenant Failure notified or required to be
notified under this Section 5.09) would reasonably be expected to result in a
Material Adverse Effect, each written notice provided by Seller to Purchaser
pursuant to this Section 5.09 which arises from an action not permitted pursuant
to Section 5.01 hereof shall be deemed (i) to have amended the applicable
Schedule or Exhibit, (ii) to have qualified the representations and warranties
contained in Article II and Article III hereof, as applicable, and (iii) to have
cured any Representation Breach and Covenant Failure that otherwise might have
existed hereunder by reason of such development solely for the purpose of
determining whether a condition set forth in Section 6.02 has been satisfied;
provided, however, that such written notification shall not be deemed to have
amended any Schedule or Exhibit, or modified any representation or warranty or
cured any breach of covenant or obligation, for purposes of determining
Purchaser's right to indemnification with respect thereto under Section 8.01(a).

            5.10 Tax Matters.

                  (a) Tax Returns. Seller shall prepare or cause to be prepared
all Income Tax Returns which include the Acquired Company or any of the
Subsidiaries for all Tax Periods ending on or prior to the Closing Date which
are filed after the Closing Date and shall file or cause to be filed all such
Consolidated Income Tax Returns (and shall promptly provide Purchaser with
copies of such Consolidated Income Tax Returns insofar as such Tax Returns
relate to the Acquired Company). Seller shall permit Purchaser at least thirty
(30) days to review and comment on each Separate Company Income Tax Return prior
to filing and shall make such revisions as are reasonably requested by the
Purchaser, and Purchaser shall execute and timely file such Separate Company
Income Tax Returns. Seller shall pay all Taxes due with respect to such Income
Tax Returns. Purchaser shall prepare or cause to be prepared (on a basis
consistent with past Tax Returns of the Acquired Company and the Subsidiaries)
and timely file or cause to be timely filed all other Tax Returns of the
Acquired Company and the Subsidiaries for Pre-Closing Tax Periods that are due
after the Closing Date (including any Straddle Period Separate Company Income
Tax Returns.) Purchaser shall permit Seller at least thirty (30) days to review
and comment on each such Tax Return prior to filing and shall make such
revisions to such Tax Returns as are reasonably requested by the Seller.
Purchaser shall pay all Taxes due with respect to such Tax Returns; provided,
however, that Seller shall pay Purchaser (in accordance with the procedures set
forth in Section 8.03(f)) for any amount owed by Seller pursuant to Section 8.03
with respect to such Straddle Period Separate Company Income Tax Returns.
Purchaser and Seller agree to cause the Acquired Company and the Subsidiaries to
file all Tax Returns for the periods including the Closing Date on the basis
that the relevant Tax Period ended as of the close of business on the Closing
Date unless the relevant Tax Authority will not accept a Tax Return filed on
that basis.

                  (b) Cooperation on Tax Matters. Purchaser and the Seller shall
cooperate fully, as and to the extent reasonably requested by the other party,
in connection with the filing of Tax Returns (including the execution thereof)
and any audit, investigation, litigation or other proceeding with respect to
Taxes, including any Tax Proceeding. Such cooperation shall

                                       33


include the retention and (upon the other party's request) the provision of
records and information which are reasonably relevant to any such audit,
litigation or other proceeding and making employees available on a mutually
convenient basis to provide additional information and explanation of any
material provided hereunder or to testify at any proceeding. If documents or
information is requested hereunder with respect to an inquiry from a
Governmental Authority, such information or documents shall be provided to the
requesting party within 25 days of the request therefor. Seller and Purchaser
agree, and Purchaser agrees to cause the Acquired Company and the Subsidiaries,
(i) to retain all books and records with respect to Tax matters pertinent to
such Acquired Company or Subsidiaries relating to any taxable period beginning
before the Closing Date until the expiration of the statute of limitations (and,
to the extent notified by Purchaser or Seller, any extensions thereof) of the
respective taxable periods, and to abide by all record retention agreements
entered into with any taxing or other Governmental Authority, and (ii) to give
the other party ninety (90) days written notice prior to transferring,
destroying or discarding any such books and records and, if the other party so
requests, Seller and Purchaser shall, and Purchaser shall cause the Acquired
Company and the Subsidiaries to, allow the other party to take possession of
such books and records. Purchaser and Seller further agree, upon request, to use
their commercially reasonable efforts to obtain any certificate or other
document from any Governmental Authority or any other Person as may be necessary
to mitigate, reduce or eliminate any Tax that could be imposed (including, but
not limited to, with respect to the transactions contemplated by this
Agreement).

                  (c) Tax Refunds. The amount or economic benefit of any refunds
of Income Taxes of the Acquired Company and/or any of the Subsidiaries for any
taxable period ending on or before the Closing Date shall be for the account of
Seller. The amount or economic benefit of any refunds of Income Taxes of the
Acquired Company for any taxable period beginning after the Closing Date shall
be for the account of Purchaser. The amount or economic benefit of any refunds
of Income Taxes of the Acquired Company and/or any of the Subsidiaries for any
period beginning before and ending after the Closing Date shall be apportioned
between Seller and Purchaser in the manner described in Section 8.03(c). Any
such amounts owing to Seller as provided in this Section 5.10(c) shall be paid
by Purchaser within five (5) Business Days of the receipt of any such refunds.
Purchaser shall not cause or permit the Acquired Company and/or any of the
Subsidiaries to carry back to any taxable period ending on or prior to the
Closing Date any net operating loss or other Tax attribute arising after the
Closing Date.

                  (d) Transfer and Other Taxes. All transfer, documentary,
sales, use, stamp, registration and other such Taxes and fees (including any
penalties and interest) incurred in connection with the Contemplated
Transactions (including any Acquired Company corporate-level gains tax triggered
by the sale of the Shares), shall be paid one-half by Seller and one-half by
Purchaser when due, and Purchaser and Seller will jointly prepare and file all
necessary Tax Returns and other documentation with respect to all such transfer,
documentary, sales, use, stamp, registration and other Taxes and fees, and, if
required by applicable law, Seller will join in the execution of any such Tax
Returns and other documentation.

                  (e) Tax Sharing Agreements. Seller shall cause the provisions
of any Tax sharing agreement or similar arrangement between Seller or any of its
Affiliates, on the one hand, and the Acquired Company and/or any of the
Subsidiaries on the other hand, to be

                                       34


terminated on or before the Closing Date with respect to such Acquired Company.
After the Closing Date, no party shall have any rights or obligations under any
such Tax sharing agreement.

                  (f) Section 338(h)(10) Election.

                        (i) With respect to the actual or deemed sale for Tax
purposes of the stock of the Acquired Company and the Subsidiaries, Seller
(and/or, to the extent necessary, its Affiliates) will join with Purchaser
(and/or, to the extent necessary, its Affiliates) to make irrevocable elections
under Section 338(h)(10) of the Code and, if permissible, similar elections
under any applicable state or local Tax laws (collectively, the "Elections").
Seller and Purchaser (and their Affiliates) shall report the transaction
consistently with the Elections and agree not to take any action that could
cause such Elections to be invalid.

                        (ii) As soon as practicable hereafter, Purchaser shall
prepare and provide to Seller any and all forms necessary to effectuate the
Elections (including, without limitation, IRS Form 8023 any similar forms under
applicable state or local tax laws (collectively, the "Section 338 Forms")).
Seller and its Affiliates shall cooperate with Purchaser in the preparation of
the Section 338 Forms and shall deliver duly executed final copies of the
Section 338 Forms on the Closing Date. Purchaser shall duly and timely file the
Section 338 Forms in accordance with applicable Tax laws and the terms of this
Agreement. Seller and Purchaser (and their Affiliates) shall cooperate with each
other to take all actions necessary and appropriate (including, without
limitation, filing such additional forms, Tax Returns, elections, schedules and
other documents as may be required) to effect and preserve the Elections in
accordance with the provisions of Regulation Section 1.338(h)(10)-1 (and
comparable provisions of each applicable state and local tax law) or any
successor provisions.

                        (iii) Within one hundred twenty (120) days after the
Closing Date, Purchaser shall prepare an allocation of the deemed sale price of
the assets of the Acquired Company and the Subsidiaries resulting from the
Elections (as required pursuant to Section 338(h)(10) of the Code and the
Regulations promulgated thereunder) among such assets (the "Section 338
Allocation"). Seller and Purchaser (and their Affiliates) shall then cooperate
in good faith to revise and finalize the Section 338 Allocation. If Seller and
Purchaser are unable to agree on the Section 338 Allocation within thirty (30)
days after Purchaser's preparation thereof, they shall request the Settlement
Accountant to prepare the Section 338 Allocation, the cost of which shall be
shared equally by them. The Section 338 Allocation shall be prepared in a manner
consistent with applicable Law, and Seller and Purchaser (and their Affiliates)
shall file all Tax Returns consistently with the Section 338 Allocation and
shall not voluntarily take any action inconsistent therewith upon examination of
any Tax Return, in any refund claim, in any litigation, or otherwise with
respect to such Tax Returns, unless required to pursuant to a determination (as
defined in Section 1313(a) of the Code or any similar state or local Tax
provision).

            5.11 Use of Name. Purchaser agrees that it shall, and shall cause
its subsidiaries (including the Acquired Company and the Subsidiaries) to, as
soon as practicable after the Closing Date and in any event within 90 days
following the Closing Date, (a) cease to (i) make any use of the name or mark
"Laidlaw" either alone or in combination with other names or marks and any
trademarks (registered or non-registered) related thereto or containing or

                                       35


comprising the foregoing, including any trademark confusingly similar thereto or
dilutive thereof (the "Laidlaw Marks"), and (ii) hold itself out as having any
affiliation with Seller or any of its Affiliates, and (b) in the case of the
Acquired Company or any of the Subsidiaries whose name includes any Laidlaw
Mark, to change its corporate name to a name that does not include any Laidlaw
Mark and to make any necessary legal filings with the appropriate Governmental
Authority to effectuate such change. In furtherance thereof, as soon as
practicable but in no event later than 90 days following the Closing Date,
Purchaser shall, and shall cause the Subsidiaries (including the Acquired
Company and the Subsidiaries) to, remove, strike over or otherwise obliterate
all Laidlaw Marks from all materials owned by the Acquired Company and the
Subsidiaries, including, without limitation, any business cards, schedules,
stationery, packaging materials, signs, promotional materials, manuals, forms,
websites, computer software and other materials. In connection herewith, Seller
hereby grants to Purchaser a non-exclusive, nontransferable, non-sublicensable
license to use the Laidlaw Marks for the period necessary to comply with the
terms of this Section 5.11 but in no event longer than 90 days following the
Closing Date solely in connection with Purchaser's operation of the Business,
which use shall be in conformity with the practices of Seller as of the Closing
Date and shall be in a manner that does not in any way harm or disparage Seller
or the reputation or goodwill of the Laidlaw Marks.

            5.12 Post-Closing Covenants. Seller and Purchaser agree to negotiate
the terms under which Seller or its Affiliates shall provide tax services to the
Acquired Company and the Subsidiaries. Notwithstanding anything to the contrary
contained in this Agreement, Article VIII shall not apply with respect to any
Contracts entered into between Seller and/or any of its Affiliates and Purchaser
pursuant to this Section 5.12.

            5.13 No Negotiation.

                  (a) Until such time, if any, as this Agreement is terminated
pursuant to Article VII, none of Seller, the Acquired Company or any Subsidiary
will, and each will cause their respective representatives not to, directly or
indirectly, solicit, initiate or encourage any inquiries or proposals from,
discuss or negotiate with, provide any non-public information to, or consider
the merits of any unsolicited inquiries or proposals from, any Person (other
than Purchaser) relating to any transaction involving the sale of any
significant portion of the Business or any significant portion of the Assets, or
any of the capital stock of the Acquired Company or any Subsidiary, or any
merger, consolidation, business combination or similar transaction involving the
Acquired Company or any Subsidiary (each, an "Acquisition Transaction").

                  (b) Seller will immediately cease and cause to be terminated
any existing discussions with any Person that relates to any Acquisition
Transaction.

                  (c) Seller agrees not to release any Person from, or to waive
or permit the waiver of any provision of, any confidentiality or similar
agreement to which Seller, the Acquired Company or any Subsidiary is a party,
and will use its best efforts to enforce or cause to be enforced each such
agreement. Seller also will promptly request each Person that has executed,
within 24 months prior to the date of this Agreement, a confidentiality or
similar agreement in connection with its consideration of a possible Acquisition
Transaction or equity investment to return all confidential information
heretofore furnished to such Person (or its representatives) by or on behalf of
Seller, the Acquired Company or any Subsidiary. At the

                                       36


Closing, Seller will assign to Purchaser, to the extent permitted by the terms
of any such confidentiality or similar agreement, the benefit of, and the right
to enforce, each confidentiality or similar agreement to which Seller is a party
relating to the Acquired Company or a Subsidiary, the Business or the Assets.

            5.14 Certain Payments. Seller will pay when due, and hold Purchaser,
the Acquired Companies and the Subsidiaries harmless from and against, any
amounts payable to any stockholder or any Named Officer of the Acquired Company
or any Subsidiary as a result of the consummation of the Contemplated
Transactions, including any "sale bonus," "change in control" payment or similar
payment.

            5.15 Riverside Road Lease Guarantee. Reimbursement Technologies,
Inc. ("RTI") is a party to that certain lease agreement, dated as of October 9,
1998, with River Park Office Associates, L.P. (the "River Park Office
Associates"), pursuant to which RTI leases certain premises located at 1000
Riverside Road, Conshohocken, PA (the "Riverside Road Lease"). Pursuant to the
terms of the Riverside Road Lease, an Affiliate of Seller has guaranteed RTI's
obligations under the Riverside Road Lease (the "Riverside Road Guarantee").
Within forty-five (45) days of the Closing Date, Purchaser shall assume (as
between Purchaser and such Affiliate) all obligations under the Riverside Road
Guarantee and shall use its commercially reasonable efforts to cause River Park
Office Associates to release such Affiliate from all obligations under the
Riverside Road Guarantee and the Riverside Road Lease. Purchaser shall indemnify
and hold harmless Seller and its Affiliates from and after the Closing for any
Damages arising out of or relating to the Riverside Road Guarantee.

            5.16 Offerings.

                  (a) In the event of a registered public offering or an
offering in accordance with Rule 144A under the Securities Act of the debt or
equity securities of Purchaser or the Acquired Company or any of their
Affiliates, Seller shall, upon Purchaser's request with reasonable prior notice,
(a) provide Purchaser with any audited balance sheets and related statements of

PricewaterhouseCoopers LLP thereon, as are reasonably requested by Purchaser,
(b) sign and deliver to PricewaterhouseCoopers LLP any representation letters
reasonably required in accordance with customary audit practices in connection
with such audited financial statements and (c) use its commercially reasonable
efforts to cause PricewaterhouseCoopers LLP to provide their consent to the
references to them as experts and the inclusion in any applicable filings of
their auditor's reports; provided, that Purchaser shall bear any and all costs
associated with the foregoing activities. In addition, Seller shall consent to
Purchaser's access to the work papers, schedules, memoranda and other documents
of PricewaterhouseCoopers LLP used or prepared by it in the course of the audit
of such audited financial statements.

                  (b) Seller agrees to use its commercially reasonable efforts
to cause the officers, employees and advisors (including independent accountants
and legal counsel) of the Acquired Company to provide cooperation in connection
with the arrangement of the financing contemplated by the Financing Commitment,
including, without limitation, reasonable

                                       37


cooperation with and participation in, meetings, due diligence sessions, road

of confidential lender information memoranda, offering memoranda, private
placement memoranda, prospectuses and similar documents, and reasonable
assistance with respect to obtaining customary closing certificates, comfort
letters of accountants, legal opinions and real estate title documentation as
may be reasonably requested by any agent, arranger, lender, underwriter, initial
purchaser or placement agent with respect to all or a portion of such financing;
provided, however, that the foregoing activities shall not unreasonably
interfere with the performance of such Person's duties in connection with the
Business; provided, further, that Purchaser shall bear all costs and expenses
associated with the foregoing; and provided, further, that to the extent Seller
or any of its Affiliates incurs any out-of-pocket costs in connection with the
foregoing, Purchaser shall promptly reimburse Seller or such Affiliate, as
applicable, for such out-of-pocket costs.

            5.17 Indemnification of Members of Committee. From and after the
date hereof, Seller shall indemnify, hold harmless and defend each Person who
serves as a member on the Committee against all Damages or expenses (including
reasonable attorneys' fees) arising out of or pertaining to acts or omissions
(or alleged acts or omissions) of such Person, or any of them, in their capacity
as members on the Committee.

            5.18 Audited Financial Statements. Seller shall deliver to Purchaser
audited financial statements for the fiscal years ended 2002, 2003 and 2004 on
or prior to December 17, 2004. Nothing contained in the audited financial
statements shall be deemed to have amended any Schedule or Exhibit, or modified
any representation or warranty or cured any breach of covenant or obligation for
purposes of determining Purchaser's right to indemnification under Section
8.01(a) with respect to the unaudited financial statements delivered pursuant to
Section 3.06(a). Such audited financial statements (including the notes thereto)
shall have been prepared in accordance with GAAP, applied on a basis consistent
throughout the periods covered thereby (except as may be indicated in the notes
to such audited financial statements; provided, however, that any such
exceptions shall not be deemed to have amended any Schedule or Exhibit, or
modified any representation or warranty or cured any breach of covenant or
obligation, for purposes of determining Purchaser's right to indemnification
with respect thereto under Section 8.01(a)), shall be consistent with the books
and records of the Acquired Company and the Subsidiaries and the unaudited
financial statements delivered pursuant to Section 3.06(a), and shall fairly
present the financial condition of the Acquired Company and the Subsidiaries as
of such date and the results of operations of the Acquired Company and the
Subsidiaries as of the dates and for periods indicated. The audit reports
delivered in connection with the audited financial statements shall contain no
limitations as to scope and no exceptions and shall state specifically that they
were performed in accordance with generally accepted auditing standards.

with the transactions contemplated by the Stock Purchase Agreement dated of even
date herewith between Parent, Seller and Purchaser regarding American Medical
Response, Inc. will not result in a change in ownership of a substantial portion
of the assets of Parent within the meaning of Code Section 280G and will not
trigger the application of Code Section 280G to any payments (within the meaning
of Code Section 280G) to be made to the Acquired Company Employees in connection
with such transactions.

warranty not so qualified shall be true and correct in all material respects, as

warranties are qualified as to materiality, shall not be deemed to be a failure
of any condition set forth in this Section 6.02(b), unless such representations
and warranties are not true and correct and the failure to be true and correct
is reasonably expected to result in a Material Adverse Effect).

                                       42


                  (q) Simultaneous with the Closing, Purchaser and Seller shall

                                   TERMINATION

            7.01 Termination. This Agreement may be terminated and the
Contemplated Transactions may be abandoned at any time prior to the Closing:

                  (a) by the mutual written agreement of Purchaser and Seller;

                  (b) by either Purchaser or Seller by giving written notice of
such termination to the other party, if the Closing shall not have occurred on
or prior to March 31, 2005 (the "Outside Date"); provided, however, that the
right to terminate this Agreement under this Section 7.01(b) shall not be
available to any party whose breach of this Agreement has been the cause of, or
resulted in, the failure of the Closing to occur on or before the Outside Date;

                  (c) by either Seller or Purchaser if (i) a statute, rule,
regulation or executive order shall have been enacted, entered or promulgated
prohibiting the consummation of the Contemplated Transactions or (ii) an Order
shall have been entered permanently restraining, enjoining or otherwise
prohibiting the consummation of the Contemplated Transactions contemplated
hereby, and such Order shall have become final and non-appealable and the party
seeking to terminate this Agreement pursuant to this clause 7.01(c)(ii) shall
have used its reasonable commercial efforts to remove such Order, and such party
shall have complied with its obligations under Section 5.03; and

                  (d) by either Seller, on the one hand, or Purchaser, on the
other hand, upon a material breach by the other of any of its obligations under
this Agreement, which breach has not been cured within twenty (20) days after
notice thereof has been provided to the breaching party; provided that there
shall be no right to terminate if such breach was caused, in whole or in part,
by a material breach by the party seeking to terminate this Agreement.

            7.02 Effect of Termination. If this Agreement is terminated as
permitted under Section 7.01, such termination shall be without liability to any
party to this Agreement or to any

                                       43


Affiliate, or their respective stockholders, directors, officers, employees,
agents, advisors or representatives, and following such termination no party
shall have any liability under this Agreement or relating to the Contemplated
Transactions by this Agreement to any other party; provided, that no such
termination shall relieve any party that has willfully breached any provision of
this Agreement from Liability for such breach, and any such breaching party
shall (A) reimburse the non-breaching party for all fees, costs and expenses
incurred by such non-breaching party in connection with this Agreement and the
transactions contemplated hereby, including but not limited to, fees and
expenses of investment bankers, accountants, and attorneys and (B) remain fully
liable for (i) any and all Damages incurred or suffered by another party to this
Agreement as a result of such breach and (ii) any other relief a court deems
appropriate. The provisions of this Section 7.02 and the Confidentiality
Agreement shall survive any termination of this Agreement and shall remain in
full force and effect. Payments for reimbursements pursuant to this Section 7.02
shall be made in cash no later than five (5) days following delivery by the
party entitled to such reimbursement to the other party, of a written notice
setting forth the amount to be reimbursed.

                                 ARTICLE VIII.
                                INDEMNIFICATION

will pay to each Purchaser Indemnified Party, the amount of all losses,

costs, expenses, interest, penalties, fines and other damages (except for
consequential, punitive, special and incidental damages and diminution in
value), all costs and expenses of investigating and defending any Proceeding and
any appeal therefrom (including reasonable attorneys' fees) and all amounts paid
incident to any compromise or settlement of any such Proceeding, in each case,
whether or not involving a third-party claim (collectively, "Damages"), arising
out of or relating to:

                        (i) any inaccuracy or breach of any representation or
warranty of Seller or Parent contained in this Agreement or any Other Seller
Document;

                        (ii) any non-compliance with or breach by Seller or
Parent at or prior to Closing of any covenant or obligation of Seller or Parent
contained in this Agreement or any Other Seller Document; or

                        (iii) any claim by any Person for brokerage or finder's
fees or commissions or similar payments based upon any agreement or
understanding alleged to have been made by any such Person with Seller, the
Acquired Company, or any Subsidiary (or any Person acting on their behalf) in
connection with any of the Contemplated Transactions.

                                       44


                  (b) Notwithstanding anything in this Agreement to the
contrary, the sole recourse of any Purchaser Indemnified Party for any and all
Damages relating to or arising from the matters set forth in Section 5.10 shall
be controlled by Section 8.03.

            8.02 Indemnification by Purchaser.

                  (a) From and after the Closing Date, Purchaser agrees to
indemnify, defend and save Seller, Parent and their respective officers,
directors, partners, stockholders employees, agents, advisors, controlling
Persons and Affiliates and their respective heirs, successors and assigns (each,
a "Seller Indemnified Party"), harmless from and against, and will pay to each
Seller Indemnified Party, the amount of all Damages arising out of or relating
to:

                        (i) any inaccuracy or breach of any representation or
warranty of Purchaser contained in this Agreement or any Other Purchaser
Document;

                        (ii) any non-compliance with or breach of any covenant
or obligation of Purchaser contained in this Agreement or any Other Purchaser
Document; or

                        (iii) Purchaser's conduct of the Business after the
Closing Date, except to the extent that any such Damages are the subject of
indemnification by Seller pursuant to Section 8.01 or to the extent it involves
Seller's or a Related Person or Seller's conduct after the Closing Date; or

                        (iv) any claim by any Person for brokerage or finder's
fees or commissions or similar payments based upon any agreement or
understanding alleged to have been made by any such Person with Purchaser (or
any Person acting on its behalf) in connection with any of the Contemplated
Transactions.

                  (b) Notwithstanding anything in this Agreement to the
contrary, the sole recourse of any Seller Indemnified Party for any and all
Damages relating to or arising from the matters set forth in Section 5.10 shall
be controlled by Section 8.03.

            8.03 Tax Indemnification.

                  (a) From and after the Closing, each of Seller and Parent,
jointly and severally, shall indemnify, save and hold harmless the Purchaser
from and against (i) all liability for U.S. federal Income Taxes or Significant
Non-Federal Income Taxes of the Acquired Company and the Subsidiaries for all
Pre-Closing Tax Periods and (ii) any and all Damages arising out of, resulting
from or incident to any breach by the Seller of any covenant contained in
Section 5.10.

                  (b) From and after the Closing, Purchaser shall indemnify,
save and hold harmless the Seller Indemnified Parties from and against (i) all
liability for U.S. federal Income Taxes or Significant Non-Federal Income Taxes
of the Acquired Company and the Subsidiaries for any Post-Closing Tax Period and
(ii) any and all Damages arising out of, resulting from or incident to the
breach by Purchaser of any covenant contained in Section 5.10.

                                       45


                  (c) In the case of any Straddle Period, the Income Taxes of
the Acquired Company and the Subsidiaries for any Pre-Closing Tax Period shall
be computed as if such taxable period ended as of the close of business on the
Closing Date.

                  (d) If an audit, investigation, claim, litigation or other
proceeding is initiated by any Governmental Authority with respect to Taxes,
which might result in an indemnity payment to a party pursuant to this Article
VIII (a "Tax Proceeding"), the notice provisions set forth in Section 8.04(a)
shall apply.

                  (e) With respect to any Tax Proceeding relating to a Tax
Period ending on or prior to the Closing Date, each of Seller and Parent shall,
upon written notification to Purchaser, control and have the right to settle all
proceedings and may make all decisions taken in connection with such Tax
Proceeding (including selection of counsel) at its own expense. Seller, Parent
and Purchaser shall jointly control all Tax Proceedings relating to Taxes of the
Acquired Company and the Subsidiaries for a Straddle Period, and neither Seller,
Parent nor Purchaser shall have the right to settle any such proceeding without
the consent of the other party, which consent shall not be unreasonably withheld
or delayed. Purchaser shall control at its own expense and have the right to
settle all Tax Proceedings relating to a tax period beginning after the Closing
Date. A party shall promptly notify the other party if it decides not to control
the defense or settlement of any Tax Proceeding which it is entitled to control
or jointly control pursuant to this Agreement, and the other party shall
thereupon be permitted to defend and settle such proceeding. Notwithstanding the
foregoing, neither party will settle any Tax Proceeding which would materially
increase the other party's taxable income without the consent of the other
party, which consent shall not be unreasonably withheld or delayed.

                  (f) Each of Seller's and Parent's indemnity obligation in
respect of Taxes for a Pre-Closing Tax Period shall initially be effected by
their payment to Purchaser of the excess of: (i) any such Taxes for a
Pre-Closing Tax Period (as may be evidenced by any Tax Return prepared by
Purchaser in accordance with Section 5.10(a) or as otherwise indicated in a
written notice prepared by Purchaser) over (ii) the amount of such Taxes paid by
Seller or any of their Affiliates (other than the Acquired Company and the
Subsidiaries) at any time plus the amount of such Taxes paid by the Acquired
Company and the Subsidiaries on or prior to the Closing Date. Seller or Parent
shall pay such excess to Purchaser within ten (10) days after written demand is
made by Purchaser (but not earlier than five (5) days before the date on which
Taxes for the relevant Tax Period are required to be paid to the relevant
Governmental Authority). If the amount of any such Taxes paid by Seller or
Parent any of their Affiliates (other than the Acquired Company and the
Subsidiaries) at any time plus the amount of such Taxes paid by the Acquired
Company and the Subsidiaries on or prior to the Closing Date exceeds the amount
of such Taxes for the Pre-Closing Tax Period, Purchaser shall pay to Seller the
amount of such excess within ten (10) days after the Tax Return with respect to
the final liability for such Taxes is required to be filed with the relevant
Governmental Authority. In the case of a Tax that is contested in accordance
with the provisions of Section 8.03(e), payment of the Tax to the appropriate
Governmental Authority shall not be considered to be due until the earlier of
(i) the date on which the Tax is paid by the party controlling the Tax
Proceeding and (ii) the date a final determination to such effect is made by the
appropriate Governmental Authority or court.

                                       46


            8.04 Indemnification Process. The party or parties making a claim
for indemnification under this Article VIII shall be, for the purposes of this
Agreement, referred to as the "Indemnified Party" and the party or parties
against whom such Claims are asserted under this Article VIII shall be, for the
purposes of this Agreement, referred to as the "Indemnifying Party". Except as
otherwise set forth in Section 8.03(e), all Claims by any Indemnified Party
under this Article VIII shall be asserted and resolved as follows:

                  (a) In the event that (i) any Proceeding is asserted or
instituted by any Person other than the parties to this Agreement or their
Affiliates which would reasonably be expected to give rise to Damages for which
an Indemnifying Party could be liable to an Indemnified Party under this
Agreement (such Proceeding, a "Third Party Claim") or (ii) any Indemnified Party
under this Agreement shall have a claim to be indemnified by any Indemnifying
Party under this Agreement which does not involve a Third Party Claim (such
claim, a "Direct Claim" and, together with Third Party Claims, "Claims"), the
Indemnified Party shall promptly, and in any event no more than fifteen (15)
days following receipt of notice of such Proceeding, send to the Indemnifying
Party a written notice specifying the nature of such Proceeding and the amount
or estimated amount thereof (which amount or estimated amount shall not be
conclusive of the final amount, if any, of such Proceeding) (a "Claim Notice"),
provided, that a delay in notifying the Indemnifying Party shall not relieve the
Indemnifying Party of its obligations under this Agreement except to the extent
that (and only to the extent that) such failure shall have caused the Damages
for which the Indemnifying Party is obligated to be greater than such Damages
would have been had the Indemnified Party given the Indemnifying Party proper
notice.

                  (b) In the event of a Third Party Claim, the Indemnifying
Party shall be entitled to appoint counsel of the Indemnifying Party's choice at
the expense of the Indemnifying Party to represent the Indemnified Party and any
others the Indemnifying Party may reasonably designate in connection with such
Proceeding (in which case the Indemnifying Party shall not thereafter be
responsible for the fees and expenses of any separate counsel retained by any
Indemnified Party except as set forth below); provided, that such counsel is
reasonably acceptable to the Indemnified Party. Notwithstanding an Indemnifying
Party's election to appoint counsel to represent an Indemnified Party in
connection with a Third Party Claim, an Indemnified Party shall have the right
to employ one separate counsel, and the Indemnifying Party shall bear the
reasonable fees, costs and expenses of such separate counsel, if (i) the use of
joint counsel for the Indemnifying Party and the Indemnified Party would be
inappropriate in the reasonable judgment of the Indemnified Party (upon and in
conformity with advice of counsel) or (ii) the Indemnifying Party shall not have
employed counsel to represent the Indemnified Party within a reasonable time
after notice of the institution of such Third Party Claim. If requested by the
Indemnifying Party, the Indemnified Party agrees to cooperate reasonably with
the Indemnifying Party and its counsel in contesting any Proceeding which the
Indemnifying Party defends, or, if appropriate and related to the Proceeding in
question, in making any counterclaim against the Person asserting the Third
Party Claim, or any cross-complaint against any Person. If the Indemnifying
Party assumes the defense of a Proceeding: (i) it will be conclusively
established for purposes of this Agreement that the Claims made in that
Proceeding are within the scope of and subject to indemnification; and (ii) no
compromise or settlement of such Claims may be effected by the Indemnifying
Party without the Indemnified Party's consent (which consent may be withheld in
the Indemnified Party's sole and absolute discretion following a reasonable
determination by the

                                       47


Indemnified Party that the conditions specified in (A) or (B) have been
satisfied) if (A) there is a finding or admission of any violation of Law which
results, or would reasonably be expected to result, in a material change in the
operation of the Business in any jurisdiction in which the Acquired Company or
any Subsidiary conducts material business or results, or would reasonably be
expected to result, in the inability or material limitation on such Person's
ability to participate in governmental reimbursement programs or (B) such
compromise or settlement provides for a material change in the operation of the
Business in any jurisdiction in which the Acquired Company or any Subsidiary
conducts material business. If notice is given to an Indemnifying Party of the
commencement of any Proceeding and the Indemnifying Party does not, within
thirty days after the Indemnified Party's notice is given, give notice to the
Indemnified Party of its election to assume the defense of such Proceeding, the
Indemnifying Party will be bound by any determination made in such Proceeding or
any compromise or settlement effected by the Indemnified Party.

                  (c) In the event of a Direct Claim, the Indemnifying Party
shall notify the Indemnified Party within 30 Business Days of receipt of a Claim
Notice whether or not the Indemnifying Party disputes such claim.

                  (d) From and after the delivery of a Claim Notice under this
Agreement, at the reasonable request of the Indemnifying Party, each Indemnified
Party shall grant the Indemnifying Party and its representatives all reasonable
access to the books, records and properties of such Indemnified Party to the
extent reasonably related to the matters to which the Claim Notice relates. All
such access shall be granted during normal business hours and shall be granted
under conditions which will not unreasonably interfere with the business and
operations of such Indemnified Party. The Indemnifying Party will not, and shall
require that its representatives do not, use (except in connection with such
Claim Notice) or disclose to any third person other than the Indemnifying
Party's representatives (except as may be required by applicable Law) any
information obtained pursuant to this Section 8.04(d) which is designated as
confidential by an Indemnified Party.

                  (e) Environmental Procedures. With respect to Seller's and
Parent's indemnification obligations relating in any way to Section 3.13, the
following additional provisions shall apply:

                        (i) If such Claim relates to the Release of a Hazardous
Substance at, on or under the real property that the Acquired Company or any
Subsidiary currently or formerly leased, the necessity for any investigation or
remediation ("Corrective Action") shall be determined pursuant to the
Environmental Laws in effect at the Closing. If Corrective Action is, or may be
required, in addition to providing access pursuant to Section 8.04(d), and for
no additional consideration, Purchaser shall permit and provide access to Seller
to conduct its own investigation, testing or Corrective Action with respect to
the matter, provided that such access shall not unreasonably interfere with the
operations of the Business;

                        (ii) Purchaser and Seller shall provide the other with
the results, including analytical data, of any investigation or testing
conducted by either of them, or, if available, any third party. Purchaser shall
also provide to Seller a copy of all Purchaser

                                       48


communications to or from any Governmental Authority, including information or
reports, with regard to any matter related to Hazardous Materials that may
constitute a Claim;

                        (iii) Except as may otherwise be required by Law,
Purchaser shall not contact any Governmental Authority with respect to the
subject matter of the indemnification Claim without prior notice to, and
consultation with, Seller. Purchaser shall, if practicable, provide Seller a
reasonable opportunity to participate in any discussions or negotiations with

Article VIII to the contrary, indemnification with respect to Claims arising out
of a breach of Seller's or Parent's representations and warranties or a breach
of Purchaser's representations and warranties, or a breach by Seller or Parent

until the aggregate amount of indemnifiable Damages asserted against Seller and
Parent, on the one hand, or Purchaser, on the other, as applicable, under this
Article VIII equals or exceeds the Liability Threshold. Once the Liability
Threshold for such Damages has been

                                       49


reached, the Indemnified Party shall be entitled to the benefit of the indemnity
under this Article VIII for such Claims, subject to Section 8.05(c) hereof, only
to the extent in excess of such Liability Threshold.

                  (b) Liability Limitation. Notwithstanding anything to the
contrary contained in this Agreement, the aggregate cumulative liability of
Seller and Parent, on the one hand, or Purchaser, on the other, for
indemnifiable Damages shall not exceed 15% of the Purchase Price (without giving
effect to the adjustment provisions set forth in Section 1.05 hereof)(the
"Cap").

                  (c) Exceptions to Liability Threshold and Cap.

                        (i) Notwithstanding anything to the contrary contained
in this Agreement, (A) neither the Liability Threshold nor the Cap shall apply
to: (1) indemnification with respect to the matters described in Section
8.01(a)(iii), (2) any Liability under Title IV of ERISA or Section 412 of the
Code with respect to any pension plan (within the meaning of Section 3(2) of
ERISA) maintained by Seller or any trade or business which is treated as a
single employer with Seller (other than the Acquired Company and the
Subsidiaries) under Sections 414(b), (c), (m) or (o) of the Code or Section
4001(a)(14) of ERISA, or (3) Claims based on fraud on the part of Seller or
Parent, and (B) each of Seller and Parent shall be jointly and severally liable
for all Damages with respect to such matters and Claims.

                        (ii) Notwithstanding anything to the contrary contained
in this Agreement, neither the Liability Threshold nor the Cap shall apply to
indemnification with respect to the matters described in Section 8.02(a)(iv) or
to Claims based on fraud on the part of Purchaser, and Purchaser shall be liable
for all Damages with respect to such matters and Claims.

                        (iii) Notwithstanding anything to the contrary contained
in this Agreement, neither the Liability Threshold nor the Cap shall apply to
indemnification with respect to the matters described in Section 8.03; provided,
however, that such matters shall be subject to the indemnification limitations
set forth in the definition of "Significant Non-Federal Income Tax."

                  (d) Adjustments to Purchase Price. Notwithstanding anything to
the contrary contained in this Agreement, no Purchaser Indemnified Party shall
be entitled to indemnification under Sections 8.01(a) or 8.03(a) hereof to the
extent Purchaser has otherwise been compensated on a dollar-for-dollar basis by
reason of a downward adjustment (made pursuant to Section 1.05 hereof) in the
Purchase Price relative to what it would have been absent such loss.

                  (e) Net Damages. Notwithstanding anything contained herein to
the contrary, the amount of any Damages incurred or suffered by an Indemnified
Party shall be calculated after giving effect to (i) any insurance proceeds
actually received by the Indemnified Party (or any of its Affiliates) with
respect to such Damages (net of any retroactive-premiums or other costs incurred
by the Indemnified Party or its Affiliates), (ii) any Tax benefit actually
realized by the Indemnified Party (or any of its Affiliates) arising from the
facts or circumstances giving rise to such Damages (net of the Tax costs to be
borne by the Indemnified Party by reason

                                       50


of the receipt of such benefit) and (iii) any net recoveries actually obtained
by the Indemnified Party (or any of its Affiliates) from any other third party.
Each Indemnified Party shall exercise commercially reasonable efforts to obtain
such proceeds, benefits and recoveries; provided, that such obligation on the
party of the Indemnified Party shall not give the Indemnifying Party the right
to delay any payment required to be paid by the Indemnifying Party pursuant to
this Article VIII. If any such proceeds, benefits or recoveries are received by
an Indemnified Party (or any of its Affiliates) with respect to any Damages
after an indemnification payment with respect thereto, the Indemnified Party (or
such Affiliate) shall promptly pay to the Indemnifying Party the amount of such
proceeds, benefits or recoveries (up to the amount of the Indemnifying Party's
payment).

                  (f) Survival of Representations and Warranties. The
representations and warranties of Seller contained in this Agreement and the
covenants of Seller under Section 5.09 hereof shall survive the Closing for the
applicable period set forth in this Section 8.05, and any and all Claims and
causes of action for indemnification under this Article VIII arising out of the
inaccuracy or breach of any representation or warranty of Seller or Purchaser
must be made prior to the termination of the applicable survival period. All of
the representations and warranties of Seller contained in this Agreement and any
and all Claims and causes of action for indemnification under this Article VIII
with respect thereto shall terminate eighteen (18) months following the Closing
Date; provided that (a) the representations and warranties of Seller contained
in Sections 2.01 (Ownership of Shares), 2.02 (Organization), 2.03 (Authority and
Binding Effect), 3.01 (Organization), 3.02 (Capitalization), Section 3.03(a)

3.19 shall survive until 90 days following the expiration of the applicable
statute or similar period of limitations; (c) the representations and warranties
of Seller contained in Section 3.13 shall survive until three (3) years
following the Closing Date; (d) the representations and warranties of Seller
contained in Section 3.10 (solely with respect to health care Laws), Section
3.11 (solely with respect to health care Laws) and Section 3.22, to the extent
any Claims under such sections arise out of matters occurring prior to June 1,
2002, shall survive until seventy-two (72) months from June 1, 2002; and (e) the
representations and warranties of Seller contained in Section 3.10 (solely with
respect to health care Laws), Section 3.11 (solely with respect to health care
Laws) and Section 3.22, to the extent any Claims under such sections arise out
of matters occurring after June 1, 2002, but prior to Closing, shall survive
until three (3) years following the Closing Date; it being understood that in
the event an Indemnified Party delivers notice of any claim for indemnification
under Section 8.01(a), Section 8.02(a), Section 8.03(a) or Section 8.03(b)
within the applicable survival period and such notice describes such Claims with
reasonable specificity, the representations and warranties that are the subject
of such indemnification claim shall survive until such time as such claim is
finally resolved. The covenants of Seller under Section 5.09 shall survive for
the same survival period as the underlying representation and warranty. If the
Closing occurs, Purchaser will have no liability pursuant to Section 8.03 unless
on or before eighteen months after the Closing Date, Seller notifies Purchaser
of a claim in accordance with Section 8.05 hereof.

            8.06 Exclusivity of Indemnification Remedy. Except for (a) fraud,
(b) agreements to be performed by the parties from and after the Closing Date,
(c) covenants of the parties pursuant to Sections 5.02(b), 5.02(c), 5.06, 5.07,
5.12 (with respect to Contracts entered into pursuant to Section 5.12), 5.14,
5.15, 5.17, 5.19 and 5.22 or (d) any equitable relief,

                                       51


including injunctive relief or specific performance, to which any party hereto
may be entitled, from and after the Closing, the indemnification for Damages
provided in this Article VIII shall be the sole and exclusive remedy of any
party hereto with respect to this Agreement, any Other Seller Document or any
Other Purchaser Document. Notwithstanding anything to the contrary contained in
this Agreement, the indemnification obligations, but not the limitation
provisions of this Article VIII, shall apply with respect to the matters
referenced in (a) through (d) above. For the avoidance of doubt, any
indemnification obligation of Seller and Parent for the matters referenced in
(a) through (d) above shall be the joint and several obligation of Seller and
Parent.
