            Whenever used in this Agreement, the following terms shall have the
meanings set forth below, and when the meaning is intended, the initial letter
of the word is capitalized:

            (a) "Agreement" means this employment agreement, as amended from
      time to time.

            (b) "AMR" means American Medical Response, Inc., a Delaware
      corporation, and, on the Effective Date, a wholly owned subsidiary of
      Purchaser.

            (c) "Base Salary" means the salary of record paid to the Executive
      as annual salary, and as further indicated in paragraph (a) of Article 4.

            (d) "Board" means the Board of Directors of the general partner of
      Purchaser unless Purchaser (or its successor) is then a corporation, in
      which event it shall mean Purchaser's Board of Directors.

            (e) "Cause" means the Executive's:

                  (i) Willful and continued failure to perform substantially the
      Executive's duties with Purchaser or a Subsidiary, which failure is not
      cured within 30 days after Purchaser delivers to the Executive written
      demand for substantial performance, specifically identifying the manner in
      which the Executive has not substantially performed his duties;

                  (ii) Conviction of an indictable offense; or

                  (iii) Willfully engaging in illegal conduct or gross
      misconduct which is materially and demonstrably injurious to Purchaser or
      a Subsidiary.

<PAGE>

      For purposes of this paragraph and Article 12, no act or omission by the
      Executive shall be considered "willful" unless it is done or omitted in
      bad faith or without reasonable belief that the Executive's action or
      omission was in the best interests of Purchaser or a Subsidiary.

            (f) "Committee" means the Compensation Committee of the Board or if
      there is no Compensation Committee, the Board.

      or cash equivalent, at least equal to an amount determined by increasing
      the amount of the initial investment, and all subsequent direct or
      indirect investments by Onex, by the total compounded annual rate of
      return of 15%, taking into account for these purposes the exercise of all
      options to purchase Units outstanding under the Plan or otherwise
      (including, without limitation, options, other equity awards or interests
      held by affiliates of Onex and their respective employees), which are then
      exercisable or become exercisable as a result of the realization of the
      15% Internal Rate of Return. Whether the 15% Internal Rate of Return has
      been realized shall be determined by the Board whose decision shall be
      final and binding on the Executive. For the avoidance of doubt, a 15%
      Internal Rate of Return shall be deemed realized only if the Investor
      Return includes both the amount of the investments and the required return
      on the investments.

            (k) "Investor Return" means the sum of all cash amounts actually
      received by Onex, on a cumulative basis through the date of determination,

      calculated based on the actual net proceeds received from the disposition
      of such Units, (b) a disposition of all or substantially all of the assets
      of Purchaser or a Subsidiary or (c) a recapitalization of Purchaser or any
      Subsidiary. Such calculation shall take into account any transaction costs
      and fees and shall exclude any management, consulting or other similar
      fees received by Onex or its affiliates.

            (l) "IPO/Recap" means an initial public offering of the equity of
      Purchaser (an "IPO") or a recapitalization of the Purchaser.

            (m) "Liquidity Event" means (i) the sale of all, or substantially
      all, of Purchaser's consolidated assets, including, without limitation, a
      sale of all or substantially all of the assets of Purchaser or any of its
      Subsidiaries whose assets constitute all or substantially all of
      Purchaser's consolidated assets in any single transaction or series of
      related transactions or (ii) any merger or consolidation of Purchaser with
      or into another entity unless, after giving effect to such merger or
      consolidation, the holders of Purchaser's partnership Units (on a
      fully-diluted basis) immediately prior to the merger or consolidation, own
      voting securities (on a fully-diluted basis) of the surviving or resulting
      corporation or other equity representing a majority of the outstanding
      voting power to elect directors of the surviving or resulting corporation

      Purchaser, and any successor thereto.

      Purchaser.

      Purchaser, including but not limited to EmCare and AMR.

                                    ARTICLE 2
                              TERM OF THE AGREEMENT

            This Agreement will be effective and binding immediately upon its
execution, but, anything in this Agreement the contrary notwithstanding, this
Agreement will not be operative until the Effective Date. The Executive's
employment pursuant to this Agreement shall commence on the Effective Date and
shall continue for a period of four years unless terminated earlier in
accordance with Article 6 hereof.

                                   ARTICLE 3
                  TITLE; COMMENCEMENT OF EMPLOYMENT; REPORTING

            The Executive shall serve as the President and Chief Operating
Officer of EmCare and of EMSC, and, at the request of Purchaser and mutual
agreement, as the Chief Operating Officer of any other Subsidiary. The
Executive's employment shall commence on the Effective Date. The Executive shall
report to the Chief Executive Officer ("CEO") of EMSC.

                                    ARTICLE 4
                                  COMPENSATION

            (a) Unless otherwise provided, all dollar amounts set forth in this
Agreement shall be in United States Dollars. The Base Salary of the Executive
for his services shall be at the annualized rate of $500,000. The Base Salary
shall be payable twice monthly on the 15th business day and last business day of
each month. The Base Salary shall be reviewed by the Board annually beginning in
the year following the first anniversary of the Effective Date during
Purchaser's normal review period. The review will be undertaken by assessing the
Executive's achievement of the overall objectives established by the Board in
consultation with the CEO and the Executive.

            (b) The Executive will be eligible to participate in a short term
incentive plan. For fiscal years commencing September 1, 2004 and thereafter,
the Executive's target bonus under such plan will be 75% of Base Salary
(pro-rated for a partial fiscal year, including the first fiscal year in the
term). The Executive's right to receive any bonus under such plan shall be
determined based upon performance targets for each fiscal year for Purchaser
fixed by the Board or the Committee during the first quarter of the year;
provided, that in the case of the partial fiscal year beginning on the Effective
Date the Executive's right to receive any bonus

                                        3
<PAGE>

under such plan shall be based on the achievement of the budget/business plan of
EmCare and AMR for the fiscal year ending August 31, 2005 approved by the board
of directors of Laidlaw International, Inc.

            (c) The Executive has agreed to co-invest in Purchaser on the
Effective Date, by purchasing the same securities purchased by the initial
equity investors at the per Unit price paid by the initial equity investors, in
the amount of $500,000. Concurrently with this co-investment by the Executive,
and pursuant to an equity option plan (the "Plan") Purchaser will adopt, the
Purchaser will grant to the Executive options to purchase one percent (1%) of
the Units outstanding on the Effective Date (the "Harvey Options"). For the
avoidance of doubt, if the agreed-upon co-investment is not made on the
Effective Date, then Purchaser shall have no obligation to grant the Harvey
Options.

            The Harvey Options, if granted, will contain the following terms and
will otherwise be subject to the terms and provisions of the Plan:

                  (i) Exercise Price. The exercise price will be the per Unit
      purchase price paid by the initial equity investors in Purchaser.

                  (ii) Vesting and Exercisability.

                        (I) 50% of the Harvey Options will become vested and
      exercisable 25% on each of the first four anniversaries of the Effective
      Date without further condition.

                        (II) 50% of the Harvey Options will become vested and
      exercisable 25% on each of the first four anniversaries of the Effective
      Date; provided, that exercisability is subject to the further condition
      that Onex has realized a 15% Internal Rate of Return.

                        (III) Notwithstanding the provisions of clause (II),
      upon the occurrence of a Liquidity Event in which Onex realizes a 15%
      Internal Rate of Return, all of the Harvey Options shall become fully
      vested and exercisable on the occurrence of the Liquidity Event, and the
      Harvey Options shall terminate and be of no further force or effect if
      they are not exercised in connection with the Liquidity Event. For the
      purposes of this clause (III) only, the 15% Internal Rate of Return shall
      be determined based on (i) cash received by Onex at any time and/or (ii)
      the fair market value of assets received by Onex at any time (as such fair
      market value is determined by the Board). Any assets received by the
      Executive in the Liquidity Event shall be subject to the same restrictions
      (such as lock-up provisions) to which the assets received by Onex are
      subject.

                        (IV) On the fourth anniversary of the Effective Date, if
      the Harvey Options referred to in clause (II) have not terminated pursuant
      to clause (III) and have vested but are not exercisable because Onex has
      not realized a 15% Internal Rate of Return, then such Harvey Options shall
      also become exercisable if:

                              (i) Purchaser has met the Cumulative Cash Flow
      Test, as such term will be defined in the Plan, or

                              (ii) if (x) Purchaser's common stock is publicly
      traded and listed on a national securities exchange and (y) Onex would
      have realized a 15%

                                        4
<PAGE>

      Internal Rate of Return if it had sold its remaining common stock interest
      in Purchaser at a per share price equal to the weighted average sale price
      of the Purchaser common stock (as quoted by such national securities
      exchange) for any 30 consecutive trading days.

                        (iii) Term. For the avoidance of doubt, options that
      have vested (by acceleration or otherwise) upon the occurrence of a
      Liquidity Event but are not exercisable because Onex has not realized a
      15% Internal Rate of Return shall terminate on the occurrence of the
      Liquidity Event, and be of no further force or effect. The occurrence of
      an IPO/Recap shall not affect the vesting of the Harvey Options.

                                   ARTICLE 5
                                    BENEFITS

            (a) AUTOMOBILE

            Purchaser will, or will cause a Subsidiary to, (i) provide the
Executive with a monthly allowance of $1,200 for expenses incurred by the
Executive for an automobile and (ii) reimburse the Executive for expenses
incurred by the Executive in connection with the related operating expenses for
such automobile, provided that the Executive provides an itemized written
account and receipts acceptable to Purchaser.

            (b) EXPENSES

            It is understood and agreed that the Executive will incur expenses
in connection with his duties under this Agreement, including, but not limited
to, travel expenses, home facsimile expenses, personal computer expenses and
telephone expenses. Purchaser shall, or shall cause a Subsidiary to, reimburse
the Executive for any such expenses provided that the Executive provides an
itemized written account and receipts acceptable to Purchaser.

            (c) VACATION

            The Executive shall be entitled to five weeks vacation during each
calendar year, prorated, however for 2005 based on the number of days remaining
in 2005 after the date of this Agreement divided by 365. The vacation shall be
taken at the discretion of the Executive with the understanding that the
Executive will take into account business needs and operations in scheduling
vacation.

            (d) WELFARE BENEFITS

            Purchaser shall, or shall cause a Subsidiary to, provide to the
Executive welfare benefit coverages (such as medical insurance, dental
insurance, short and long-term disability insurance and group term life
insurance) in accordance with employee benefit plans and policies maintained by
Purchaser or a Subsidiary for the benefit of its employees of Purchaser, and as
amended from time to time; provided, however, that Purchaser shall, or shall
cause a Subsidiary to, reimburse the Executive for premiums paid by the
Executive, if any, for coverage under such employee benefit plans and policies.
Further, Purchaser shall, or shall cause a Subsidiary to, provide the Executive
with additional term life insurance that, in conjunction with coverage under the
group life insurance programs provided to the Executive, provides coverage in an
amount equal to three times the Executive's Base Salary.

            (e) EXECUTIVE RELOCATION ALLOWANCE

            If the Executive relocates to Dallas, Texas or Denver, Colorado
prior to the first anniversary of the Effective Date, the Executive shall be
entitled to reimbursement of customary moving and transportation expenses in
connection with the Executive's relocation to Dallas, Texas or Denver, Colorado,
as applicable.

                                   ARTICLE 6
                            TERMINATION OF EMPLOYMENT

            (a) Notwithstanding the provisions of Article 2 of this Agreement,
the parties understand and agree that this Agreement and the Executive's
employment hereunder may be terminated in the following manner in the specified
circumstances:

                  (i) By the Executive, at any time, for any reason, on the
      giving of 90 days' written notice to Purchaser. Purchaser may waive
      notice, in whole or in part, upon immediate payment to the Executive of
      the Executive's Base Salary for such portion of the 90-day notice period
      as is waived by Purchaser. Upon such termination, Purchaser may elect, in
      its sole and absolute discretion, to pay the Executive his Base Salary in
      effect at the time of such termination for a period of up to 24 months
      following such termination as consideration for Executive's agreement set
      forth in paragraph (b) of this Article 6.

                  (ii) By Purchaser, for Cause, without any pay and without any
      notice (other than any notice and opportunity to cure as provided in
      clause (i) of the definition of "Cause").

                  (iii) By Purchaser, in its absolute discretion and for any
      reason, without Cause. Upon such termination, Purchaser shall (A) continue
      to pay the Executive his Base Salary in effect at the time of such
      termination for a period of 24 months following such termination, (B)
      continue to provide the Executive medical insurance, dental insurance and
      term life insurance (but excluding the life insurance referred to in the
      last sentence of paragraph (d) in Article 5) during the applicable
      termination period, or, if such benefits cannot be provided, Purchaser
      shall, or shall cause a Subsidiary to, pay to the Executive an equivalent
      lump sum cash amount in lieu of such benefits, and (C) if the performance
      targets for the year are met, pay to Executive a pro rata portion (equal
      to a fraction, of which the numerator is the number of full months of
      Executive's employment in the year and the denominator is 12), of the
      bonus payable to Executive pursuant to Section 4(b), at such time as the
      Company pays annual incentive bonuses for the year to executives of the
      Purchaser.

                  (iv) The Executive may terminate employment with Purchaser or
      any Subsidiary with the right to severance compensation as provided in
      Article 6(a)(iii)(A) and (B) upon the occurrence of a Change in Control
      followed by one or more of the following events:

                  (A)   Failure to elect or reelect or otherwise to maintain the
                        Executive in the office or position, or a substantially
                        equivalent office or position, of or with Purchaser
                        which the Executive held immediately prior to the Change
                        in Control;

                                        6
<PAGE>

                  (B)   (1) A significant adverse change in the nature or scope
                        of the authorities, powers, functions, responsibilities
                        or duties attached to the position with Purchaser which
                        the Executive held immediately prior to the Change in
                        Control, (2) a reduction in the aggregate of the
                        Executive's Base Salary received from Purchaser or the
                        value of the Executive's incentive pay opportunity from
                        Purchaser or its Subsidiaries, or (3) the termination of
                        the Executive's rights to employee benefits or a
                        reduction in the scope or value thereof to a level that
                        is substantially lower in the aggregate from the level
                        in effect at the time of the Change in Control, any of
                        which is not remedied by Purchaser with 10 calendar days
                        after receipt by Purchaser of written notice from the
                        Executive of such change, reduction, or termination, as
                        the case may be; or

                  (C)   The liquidation, dissolution, merger, consolidation or
                        reorganization of Purchaser or transfer of all or
                        substantially all of its business and/or assets, unless
                        the successor or successors (by liquidation, merger,
                        consolidation, reorganization, transfer or otherwise) to
                        which all or substantially all of its business and/or
                        assets have been transferred (by operation of law or
                        otherwise) assumed all duties and obligations of
                        Purchaser.

            In order to receive the entitlement under paragraphs 6(a)(i) and
6(a)(iii), the Executive must undertake to sign a release in a form satisfactory
to Purchaser, fully releasing Purchaser, from further claims upon payment of the
amounts stipulated herein. However, the form of release shall not require that
the Executive give up any rights of indemnity which the Executive may have had
as against Purchaser for acts carried out by the Executive in the ordinary
course of Purchaser's business.

            (b) The Executive agrees that during employment pursuant to this
Agreement and for 24 months following termination of his employment as long as
there is payment of the severance payment amount and benefit continuation, if
applicable, as detailed in subparagraphs (i) and (iii) of paragraph (a) of this
Article 6, he will not compete, solicit or accept business with respect to
products competitive with those of Purchaser from any of Purchaser's customers,
wherever situated, and he shall not either individually or in partnership, or
jointly in conjunction with any other person, entity or organization, as
principal, agent, consultant, lender, contractor, employer, employee, investor,
shareholder, or in any other manner, directly or indirectly, advise, manage,
carry on, establish, control, engage in, invest in, offer financial assistance
or services to, or permit his name to be used by any business that competes with
the then-existing business of Purchaser or any Subsidiary, provided that the
Executive shall be entitled, for investment purposes, to purchase and trade
shares of a public company which are listed and posted for trading on a
recognized stock exchange and the business of which public company may be in
competition with the business of Purchaser or any Subsidiary, provided that the
Executive shall not directly or indirectly own more than five percent (5%) of
the issued share capital of the public company, or participate in its management
or operation, or in any advisory capacity within the time limits set out herein.

            For purposes of the obligations set out herein, the business of
Purchaser shall mean the provision of (a) critical care transportation services,
non-emergency ambulance and transfer services and emergency response services
and/or (b) emergency management

                                        7

services to hospital-based emergency departments and freestanding emergency
clinics and (c) in-patient hospitalist services.

            (c) The Executive further agrees that for a period of 24 months
following termination of employment, however caused, he will not solicit for
hire or rehire, or take away, or cause to be hired, or taken away, employee(s)
of Purchaser.

merger or consolidation, own voting securities (on a fully-diluted basis) of the
surviving or resulting entity representing a majority of the outstanding voting

outside the scope of this Agreement, without the express approval of the CEO.

            D. The Executive shall not serve as an officer or director (or the
equivalent position) of any entity other than the Company or its affiliates or
managed entities, and shall not receive fees or other remuneration for work
performed outside the scope of his employment without prior written consent of

shall be reviewed by the Board annually during the Company's normal review
period, beginning in the year following the first anniversary of the Effective
Date.

            B. The Executive will be eligible to participate in a short-term
incentive plan. For fiscal years commencing September 1, 2004 and thereafter,
the Executive's target bonus under such plan will be 50% of Base Salary
(pro-rated for a partial fiscal year, including the first fiscal year in the
term). The Executive's right to receive any bonus under such plan shall be
determined based upon performance targets for each year fixed by the Board or a
duly authorized committee thereof; provided, that in the case of the partial
fiscal year beginning on the Effective Date the Executive's right to receive any
bonus under such plan shall be based on the achievement of the budget/business
plan of EmCare and AMR for the fiscal year beginning August 31, 2004 approved by
the board of directors of Laidlaw International, Inc.

            C. The Executive has agreed to co-invest in the Company on the
Effective Date, by purchasing the same securities purchased by the initial
equity investors at the per Partnership Unit price paid by the initial equity
investors, in the amount of $200,000. Concurrently with this co-investment by
the Executive, and pursuant to an equity option plan (the "Plan") the Company
will adopt, the Company will grant to the Executive options to purchase one
percent (1%) of the Partnership Units outstanding on the Effective Date (the
"Owen Options"). For the avoidance of doubt, if the agreed-upon co-investment is
not made on the Effective Date, then the Company shall have no obligation to
grant the Owen Options.

            The Owen Options, if granted, will contain the following terms and
will otherwise be subject to the terms and provisions of the Plan:

                  1. Exercise Price. The exercise price will be the per
      Partnership Unit purchase price paid by the initial equity investors in
      the Company.

                  2. Vesting and Exercisability.

                        a. 50% of the Owen Options will become vested and
      exercisable 25% on each of the first four anniversaries of the Effective
      Date without further condition.

                        b. 50% of the Owen Options will become vested and
      exercisable 25% on each of the first four anniversaries of the Effective
      Date; provided, that exercisability is subject to the further condition
      that Onex has realized a 15% Internal Rate of Return.

                                        4
<PAGE>

                        c. Notwithstanding the provisions of clause (b), upon
      the occurrence of a Liquidity Event in which Onex realizes a 15% Internal
      Rate of Return, all of the Owen Options shall become fully vested and
      exercisable on the occurrence of the Liquidity Event, and the Owen Options
      shall terminate and be of no further force or effect if they are not
      exercised in connection with the Liquidity Event. For the purposes of this
      clause (c) only, the 15% Internal Rate of Return shall be determined based
      on (i) cash received by Onex at any time and/or (ii) the fair market value
      of assets received by Onex at any time (as such fair market value is
      determined by the Board). Any assets received by the Executive in the
      Liquidity Event shall be subject to the same restrictions (such as lock-up
      provisions) to which the assets received by Onex are subject.

                        d. On the fourth anniversary of the Effective Date, if
      the Owen Options referred to in clause (b) have not terminated pursuant to
      clause (c) and have vested but are not exercisable because Onex has not
      realized a 15% Internal Rate of Return, then such Owen Options shall also
      become exercisable if:

            (i)   the Company has met the Cumulative Cash Flow Test, as such
                  term will be defined in the Plan, or

            (ii)  if (x) the Company's common stock is publicly traded and
                  listed on a national securities exchange and (y) Onex would
                  have realized a 15% Internal Rate of Return if it had sold its
                  remaining common stock interest in the Company at a per share
                  price equal to the weighted average sale price of the Company
                  common stock (as quoted by such national securities exchange)
                  for any 30 consecutive trading days.

                  3. Term. For the avoidance of doubt, options that have vested
      according to paragraph 4.C.2.b (by acceleration or otherwise) upon the
      occurrence of a Liquidity Event but are not exercisable because Onex has
      not realized a 15% Internal Rate of Return shall terminate on the
      occurrence of the Liquidity Event, and be of no further force or effect.
      The occurrence of an IPO/Recap shall not affect the vesting of the Owen
      Options.

      5. Fringe Benefits; Expenses.

            A. The Executive shall be entitled to welfare benefit coverages
(such as medical insurance, dental insurance, short- and long-term disability
insurance and group term life insurance) in accordance with employee benefit
plans and policies maintained by the Company for the benefit of similarly
situated executives of the Company. Without limiting the foregoing, the
Executive shall be entitled to term life insurance that, in conjunction with
coverage under the group life insurance programs provided to the Executive,
provides coverage in an amount equal to three times the Executive's Base Salary.

            B. The Executive shall be entitled to participate in any and all
equity plans of the Company on a basis equal to other similarly situated
executives of the Company.

            C. The Company shall reimburse, or shall cause a Subsidiary to
reimburse, the Executive for all reasonable and necessary expenses incurred by
him in connection with the performance of services hereunder, in accordance with
the Company's policies and procedures applicable to similarly situated
executives of the Company.

                                        5
<PAGE>

            D. The Executive shall be entitled to such vacation time per
calendar year as is applicable to similarly situated executives of the Company,
but in no event less than three weeks per calendar year; the use of which
vacation time shall be subject to prior approval by the CEO.

            E. The Company shall obtain and maintain directors and officers
liability insurance policies covering Executive's actions hereunder on the same
terms as similarly situated executives of the Company.

            F. The Company shall, or shall cause a Subsidiary to, (i) provide
the Executive with a monthly allowance of $1,200 for expenses incurred by the
Executive for the leasing of an automobile and (ii) reimburse the Executive for
expenses incurred by the Executive in connection with the related operating and
insurance expenses for such automobile, provided that the Executive provides an
itemized written account and receipts acceptable to the Company.

      6. Disability or Death.

            A. If, as the result of any physical or mental disability, the
Executive shall have failed or is unable to perform his duties for a period of
90 consecutive days, the Company may, by notice to the Executive subsequent
thereto, terminate this Agreement as of the date of the notice without any
further payment or the furnishing of any benefit by the Company under this
Agreement, unless otherwise required by applicable law.

            B. The term of the Executive's employment under this Agreement shall
terminate upon his death without any further payment or the furnishing of any
benefit by the Company under this Agreement (other than accrued and unpaid Base
Salary and expenses and benefits which have accrued pursuant to any plan or by
law).

      7. Termination.

            A. The Company shall have the right to terminate this Agreement
immediately for cause in the event of the occurrence of any of the following:

                  1. Fraud, theft, gross misconduct or gross negligence on the
      part of the Executive, including, without limitation, conduct of a
      felonious or criminal nature, conduct involving moral turpitude,
      embezzlement, misappropriation of assets or substantial neglect of duties;

                  2. Alcohol or drug abuse that impairs the Executive's ability
      to properly perform his duties;

                  3. Violation of the Company's Corporate Compliance Policy; or

                  4. A material breach of the Agreement by the Executive which
      has not been cured within 30 days of receipt by Executive of written
      notice of the breach.

            B. Either party may terminate this Agreement without cause by
providing the other party with 90 days prior written notice of termination. If
termination is by Executive, the Company may waive notice, in whole or in part,
upon immediate payment to the Executive of the Executive's Base Salary for such
portion of the 90-day notice period as is waived by the

                                        6
<PAGE>

Company. Upon such termination, the Company may elect, in its sole and absolute
discretion, to pay the Executive his Base Salary in effect at the time of such
termination for a period of up to 24 months following such termination as
consideration for Executive's agreement set forth in paragraph 9.A.

            C. Executive may terminate this Agreement in the event of a material
breach of the Agreement by the Company which has not been cured within 30 days
of receipt by the Company of written notice of the breach.

            D. The Executive may terminate employment with the Company and any
Subsidiary with the right to severance compensation as provided in paragraph
8.B. upon the occurrence of a Change in Control followed by one or more of the
following events:

                  1. Failure to elect or reelect or otherwise to maintain the
      Executive in the office or position, or a substantially equivalent office
      or position, of or with the Company which the Executive held immediately
      prior to the Change in Control;

                  2. (a) A significant adverse change in the nature or scope of
      the authorities, powers, functions, responsibilities or duties attached to
      the position with the Company which the Executive held immediately prior
      to the Change in Control, (b) a reduction in the aggregate of the
      Executive's Base Salary received from the Company or the value of the
      Executive's incentive pay opportunity from the Company or its
      Subsidiaries, or (c) the termination of the Executive's rights to employee
      benefits or a reduction in the scope or value thereof to a level that is
      substantially lower in the aggregate from the level in effect at the time
      of the Change in Control, any of which is not remedied by the Company with
      10 calendar days after receipt by the Company of written notice from the
      Executive of such change, reduction, or termination, as the case may be;
      or

                  3. The liquidation, dissolution, merger, consolidation or
      reorganization of the Company or transfer of all or substantially all of
      its business and/or assets, unless the successor or successors (by
      liquidation, merger, consolidation, reorganization, transfer or otherwise)
      to which all or substantially all of its business and/or assets have been
      transferred (by operation of law or otherwise) assumed all duties and
      obligations of the Company.

      8. Salary/Benefit Continuation.

            A. Upon termination of this Agreement by the Company for cause or in
the event of the Executive's termination of this Agreement without cause,
Executive shall be entitled to receive all salary earned under this Agreement up
to the date of termination.

            B. Upon termination of this Agreement by the Company without cause
or in the event of the Executive's termination of this Agreement in accordance
with paragraph 7.C , the Executive shall be entitled to receive the following:

                  1. All salary earned under this Agreement up to the date of
      termination; and

                  2. Base compensation at the rate payable on the date
      immediately prior to termination for an additional period of 24 months
      (or, in any Renewal Term, for

                                        7
<PAGE>

      the number of months remaining in the Renewal Term or, in Purchaser's sole
      and absolute discretion, for a longer period, up to a maximum of 24
      months); and

                  3. For a period of 24 months following the date of termination
      (or, in any Renewal Term, for the number of months remaining in the
      Renewal Term or, in Purchaser's sole and absolute discretion, for a longer
      period, up to a maximum of 24 months), the Company shall continue to pay
      for the cost of Executive's participation in the Company's group medical
      and dental insurance plans and group term life insurance (but excluding
      the life insurance referred to in the last sentence of paragraph 5.A) at
      the same rate as applicable to Executive immediately prior to termination,
      provided that Executive is entitled to continue such participation under
      applicable state and federal law and under the terms of the Company's
      employment benefit plans in effect at the time (including provisions in
      the Company's medical and dental plans related to coordination with other
      insurance, as applicable); and

                  4. If the performance targets for the year are met, a prorata
      portion (equal to a fraction, of which the numerator is the number of full
      months of Executive's employment in the year and the denominator is 12),
      of the bonus payable to Executive pursuant to paragraph 4.B., payable at
      such time as the Company pays annual incentive bonuses for the year to
      executives of the Company.

            C. Upon termination of this Agreement by Executive in accordance
with paragraph 7.D, the Executive shall be entitled to receive the compensation
set forth in paragraphs 8.B.1, 8.B.2 and 8.B. 3.

            D. As a condition to receipt of the items set forth in paragraph
8.B.2, 8.B.3 and 8.B.4, as applicable, Executive shall execute promptly upon
termination a Settlement and Release Agreement, pursuant to which Executive
shall release the Company from any and all claims and demands which Executive
may possess against the Company.

      9. Restrictive Covenants.

            A. Executive agrees that during the term of this Agreement, and for
24 months thereafter, Executive will not in any manner, without the prior
written consent of the Company, directly or indirectly: (1) disclose or divulge
to any person, entity, firm, company or employer, or use for Executive's own
benefit or the benefit of any other person, entity, firm, company or employer
directly or indirectly in competition with the Company, any knowledge,
information, business methods, techniques or data of the Company; (2) solicit,
divert, take away or interfere with any of the customers, accounts, trade,
business patronage, employees or contractual arrangements of the Company; (3)
compete with the Company or enter into any contractual arrangements for the
provision of medical transportation services, medical triage, or physician
coverage or management services with any governmental authority, provider or
hospital with which Executive has come into contact while an employee of the
Company; or (4) either individually or in partnership, or jointly in conjunction
with any other person, entity or organization, as principal, agent, consultant,
lender, contractor, employer, employee, investor, shareholder, or in any other
manner, directly or indirectly, advise, manage, carry on, establish, control,
engage in, invest in, offer financial assistance or services to, or permit his
name to be used by any business that competes with the then-existing business of
the Company, provided that the Executive shall be entitled, for investment
purposes, to purchase and trade shares of a public company which are listed and
posted for trading on a recognized stock exchange and the business of which
public company may be in competition with the business of the Company,

                                        8
<PAGE>

provided that the Executive shall not directly or indirectly own more than five
percent (5%) of the issued share capital of the public company, or participate
in its management or operation, or in any advisory capacity within the time
limits set out herein. Solely for the purposes of this paragraph 9, the term
"Company" shall mean the Company, its subsidiaries, its affiliates, their
subsidiaries and companies for whom such entities provide services.

            B. Executive further agrees that for a period of 24 months following
termination of employment, however caused, he will not solicit for hire or
rehire, or take away, or cause to be hired, or taken away, employee(s) of the
Company.

            C. It is the intention of the parties to restrict the activities of
Executive in a manner which reasonably protects the legitimate business
interests of the Company. In the event this paragraph 9 is deemed overly broad
or unenforceable by a court of competent jurisdiction, it is the intent of the
parties that this paragraph be enforced to the fullest extent allowed under
applicable law, and be reformulated by such court to the extent necessary to so
enforce it.

            D. Executive agrees that the damages and remedies at law for any
breach under this paragraph would be inadequate and that, in addition, in the
event of a breach under this paragraph, the Company may apply to a court of
competent jurisdiction and be entitled to an injunction by such court to prevent
a breach or further breach thereof on the part of the Executive. Such injunction
shall be in addition to damages or other relief afforded under this Agreement.

            E. The Executive acknowledges that the agreements provided in this
Section 9 were an inducement to the Company to enter into this Agreement and
that the remedy at law for breach of his covenants under this Section 9 will be
inadequate. Accordingly, in the event of any breach or threatened breach by the
Executive of any provision of this Section 9, the Company shall be entitled, in
addition to all other remedies, to an injunction restraining any breach by
Executive.

      10. Miscellaneous.

            A. This Agreement shall become operative automatically on the
Effective Date and, as of the Effective Date, shall constitute the entire
agreement between the parties with respect to the employment and appointment of
the Executive and any and all previous agreements, written or oral, express or
implied, between the parties or on their behalf, relating to the employment and
appointment of the Executive by the Company or any Subsidiary, are terminated
and cancelled effective on the Effective Date and each of the parties releases
and forever discharges the other of and from all manner of actions, causes of
action, claims and demands whatsoever, under or in respect of any previous
agreement, including without limitation, the Agreement, dated as of May 1, 2004,
between AMR and the Executive which is hereby terminated and cancelled effective
on the Effective Date. If the Effective Date does not occur on or before March
31, 2005, this Agreement shall become null and void and of no further force and
effect.

            B. This Agreement shall be governed by and construed in accordance
with the laws of the State of Delaware applicable to agreements made and
performed in Delaware, and shall be construed without regard to any presumption
or other rule requiring construction against the party causing the Agreement to
be drafted.

                                        9

            C. This Agreement cannot be modified, amended, or terminated orally.
Amendments may be made to this Agreement at any time if mutually agreed upon in
writing.

            D. Any amendment, notice, or other communication under this
Agreement shall be in writing and shall be considered given when received and

            If to Executive:     Last known address on file with the Company

            E. The failure of a party to insist upon strict adherence to any
term of this Agreement on any occasion shall not be considered a waiver or
deprive that party of the right thereafter to insist upon strict adherence to
that term or any other term of this Agreement. Any waiver must be in writing.

            F. Each of the parties irrevocably submits to the exclusive
jurisdiction of any court of the State of Delaware and consents that any action,
suit, or proceeding relating to or arising out of this Agreement and the
transactions contemplated hereby may be brought in such court.

            G. The invalidity or unenforceability of any term or provision of
this Agreement shall not affect the validity or enforceability of the remaining
terms or provisions of this Agreement which shall remain in full force and
effect and any such invalid or unenforceable term or provision shall be given
full effect as far as possible. If any term or provision of this Agreement is
invalid or unenforceable in one jurisdiction, it shall not affect the validity
or enforceability of that term or provision in any other jurisdiction.

            H. This Agreement is not assignable by either party except that it
shall inure to the benefit of and be binding upon any successor to the Company
by merger or consolidation or the acquisition of all or substantially all of the
Company's assets, provided such successor assumes all of the obligations of the
Company, and shall inure to the benefit of the heirs and legal representatives
of the Executive.

            I. The parties acknowledge that none of the benefits granted to
either party hereunder are conditioned on any requirement that either party make
referrals to, be in a position to make or influence referrals to, or otherwise
generate business for the other.

            J. If the Executive is made a party to any action, suit, proceeding
or any other claim whatsoever, by reason of the fact that the Executive is or
was a director, officer, employee or agent of the Company and one or more
Subsidiaries, or is or was serving at the request of Company and one or more
Subsidiaries, as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, whether or not the basis
of such claim is the Executive's alleged action in an official capacity while in
service as a director, officer, employee or agent of the Company and one or more
Subsidiaries the Executive shall be

                                       10

fullest extent legally permitted or authorized by the Company's and such
Subsidiaries' certificate of incorporation or bylaws or resolutions of the Board
against all expenses, liability and loss, including, without limitation, legal
fees, fines or penalties and amounts paid or to be paid in settlement, all as
reasonably incurred by the Executive in connection therewith, and such
indemnification shall continue as to the Executive even after the Executive has
ceased to be a director, officer, employee or agent of the Company or such
Subsidiaries, and shall inure to the benefit of the Executive's heirs, executors
and administrators.

      IN WITNESS WHEREOF, the Company and Executive have executed this
Agreement, in multiple counterparts, each of which shall be deemed an original,
effective the day and year first above written.
