surviving or resulting entity representing a majority of the outstanding voting

request, as Chief Financial Officer of one or more Subsidiaries, and the
Executive shall serve in such capacity, performing such duties as are consistent
with the position, along with such other duties and responsibilities assigned to
the Executive by the Chief Executive Officer ("CEO") of EMSC. The Executive
shall devote his best efforts to the performance of his duties under this
Agreement and shall perform them faithfully, diligently, competently and in a
manner consistent with the policies of the Company as determined from time to
time by the CEO or President of the Company.

            B. The Executive shall report to the CEO on all matters pertaining
to his duties hereunder.

            C. The Executive shall not engage in other business activities
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
the CEO.

      3. Term of Employment. This Agreement will be effective and binding
immediately upon its execution, but, anything in this Agreement to the contrary
notwithstanding, this

                                        3
<PAGE>

Agreement shall not be operative until the Effective Date. The Executive's
employment under this Agreement shall commence on the Effective Date, shall
continue for a period of three years, and shall be renewed for additional one
year periods thereafter (each a "Renewal Term") unless either party informs the
other in writing within 90 days of this Agreement's expiration that it does not
wish to renew the Agreement, or unless sooner terminated as provided in this
Agreement.

      4. Compensation.

            A. As full compensation for all services rendered by the Executive
pursuant to this Agreement, the Company shall pay, or shall cause a Subsidiary
to pay, to the Executive a salary of $350,000 per year ("Base Salary"), less
applicable withholdings. The Base Salary shall be payable twice monthly on the
15th business day and last business day of each month. Executive's compensation
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.

            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

                  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

<PAGE>

      the number of months remaining in the Renewal Term or, in Purchaser's sole

      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

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

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

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

Subsidiaries, and shall inure to the benefit of the Executive's heirs, executors
and administrators.
