1.              General

Basis of Presentation of Financial Statements

The accompanying interim consolidated financial statements for Emergency Medical Services Corporation (“EMSC” or the “Company”) have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim reporting and accordingly, do not include all of the disclosures required for annual financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included. All such adjustments are of a normal, recurring nature. Operating results for the three months ended March 31, 2010 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2010. For further information, see the Company’s consolidated financial statements, including the accounting policies and notes thereto, included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2009.

The consolidated financial statements of EMSC include those of its direct subsidiary, Emergency Medical Services L.P. (“EMS LP”), a Delaware limited partnership. The Company’s business is conducted primarily through two operating subsidiaries, American Medical Response, Inc. (“AMR”), its healthcare transportation services segment, and EmCare Holdings Inc. (“EmCare”), its facility-based physician services segment.

The Company is party to a management agreement with a wholly-owned subsidiary of Onex Corporation, the Company’s principal equityholder. In exchange for an annual management fee of $1.0 million, the Onex subsidiary provides the Company with corporate finance and strategic planning consulting services. For each of the three months ended March 31, 2010 and 2009, the Company expensed $250 in respect of this fee.

2.              Summary of Significant Accounting Policies

Consolidation

The consolidated financial statements include all wholly-owned subsidiaries of EMSC, including AMR and EmCare and their respective subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements requires management to make estimates and assumptions relating to the reporting of results of operations, financial condition and related disclosure of contingent assets and liabilities at the date of the financial statements. Actual results may differ from those estimates under different assumptions or conditions.

Insurance

Insurance collateral is comprised principally of government and investment grade securities and cash deposits with third parties and supports the Company’s insurance program and reserves. Certain of these investments, if sold or otherwise liquidated, would have to be replaced by other suitable financial assurances and are, therefore, considered restricted.

Insurance reserves are established for automobile, workers compensation, general liability and professional liability claims utilizing policies with both fully-insured and self-insured components. This includes the use of an off-shore captive insurance program through a wholly-owned subsidiary for certain professional liability (malpractice) programs for EmCare. In those instances where the Company has obtained third-party insurance coverage, the Company normally retains liability for the first $1 to $2 million of the loss. Insurance reserves cover known claims and incidents within the level of Company retention that may result in the assertion of additional claims, as well as claims from unknown incidents that may be asserted arising from activities through the balance sheet date.

The Company establishes reserves for claims based upon an assessment of actual claims and claims incurred but not reported.  The reserves are established based on quarterly consultation with third-party independent actuaries using actuarial principles and assumptions that consider a number of factors, including historical claim payment patterns (including legal costs) and changes in case reserves and the assumed rate of inflation in healthcare costs and property damage repairs.

The Company’s most recent actuarial valuation was completed in March 2010. As a result of this and previous actuarial valuations, the Company recorded a decrease in its provisions for insurance liabilities of approximately $2.8 million in the three months ended March 31, 2010 compared to an increase of $0.7 million during the same period in 2009 related to

6

Table of Contents

reserves for losses in prior years.

The long-term portion of insurance reserves was $150.2 million and $143.6 million as of March 31, 2010 and December 31, 2009, respectively.

Trade and Other Accounts Receivable, net

The Company determines its allowances based on payor reimbursement schedules, historical write-off experience and other economic data. The allowances for contractual discounts and uncompensated care are reviewed monthly. Account balances are charged off against the uncompensated care allowance when it is probable the receivable will not be recovered. Write-offs to the contractual allowance occur when payment is received. The allowance for uncompensated care is related principally to receivables recorded for self-pay patients.  The Company’s accounts receivable and allowances are as follows:

Other receivables represent EmCare hospital subsidies and fees and AMR fees for stand-by and special events and subsidies from community organizations.

AMR contractual allowances are determined primarily on payor reimbursement schedules that are included and regularly updated in the billing systems, and by historical collection experience.  The billing systems calculate the difference between payor specific gross billings and contractually agreed to, or governmentally driven, reimbursement rates.  The allowance for uncompensated care at AMR is related principally to receivables recorded for self-pay patients.  AMR’s allowances on self-pay accounts receivable are estimated on claim level, historical write-off experience.

Accounts receivable allowances at EmCare are estimated based on cash collection and write-off experience at a facility level contract and facility specific payor mix.  These allowances are reviewed and adjusted monthly through revenue provisions.  In addition, a look-back analysis is done, typically after 15 months, to compare actual cash collected on a date of service basis to the revenue recorded for that period.  Any adjustment necessary for an overage or deficit in these allowances based on actual collections is recorded through a revenue adjustment in the current period.

Revenue Recognition

Revenue is recognized at the time of service and is recorded net of provisions for contractual discounts and estimated uncompensated care. Provisions for contractual discounts and estimated uncompensated care as a percentage of gross revenue and as a percentage of gross revenue less provision for contractual discounts are as follows:

Healthcare reimbursement is complex and may involve lengthy delays. Third-party payors are continuing their efforts to control expenditures for healthcare, including proposals to revise reimbursement policies. The Company has from time to time experienced delays in reimbursement from third-party payors. In addition, third-party payors may disallow, in whole or in part, claims for reimbursement based on determinations that certain amounts are not reimbursable under plan coverage, on determinations of medical necessity, or the need for additional information. Laws and regulations governing the Medicare and Medicaid programs are very complex and subject to interpretation. Revenue is recognized on an estimated basis in the period in which related services are rendered.  As a result, there is a reasonable possibility that recorded estimates will

Table of Contents

change materially in the short-term. Such amounts, including adjustments between provisions for contractual discounts and uncompensated care, are adjusted in future periods, as adjustments become known.  These adjustments were less than 1% of net revenue for the three month periods ended March 31, 2010 and 2009.

The Company also provides services to patients who have no insurance or other third-party payor coverage. In certain circumstances, federal law requires providers to render services to any patient who requires emergency care regardless of their ability to pay.

Equity Structure

On December 21, 2005, the Company effected a reorganization and issued 8.1 million shares of class A common stock in an initial public offering. Pursuant to the reorganization, EMS LP, the former top-tier holding company of AMR and EmCare, became the consolidated subsidiary of EMSC, a newly formed corporation. To effect the reorganization, the holders of the capital stock of the sole general partner of EMS LP contributed that capital stock to the Company in exchange for class B common stock; the general partner was merged into the Company and the Company became the sole general partner of EMS LP. Concurrently, the holders of class B units of EMS LP contributed their units to the Company in exchange for shares of the Company’s class A common stock, and the holders of certain class A units of EMS LP contributed their units to the Company in exchange for shares of the Company’s class B common stock.

As of March 31, 2010, the Company holds 68.7% of the equity interests in EMS LP. LP exchangeable units, held by persons affiliated with the Company’s principal equity holder, represent the balance of the EMS LP equity. The LP exchangeable units are exchangeable at any time, at the option of the holder, for shares of the Company’s class B common stock on a one-for-one basis. The holders of the LP exchangeable units have the right to vote, through the trustee holder of the Company’s class B special voting stock, at all stockholder meetings at which holders of the Company’s class B common stock or class B special voting stock are entitled to vote.

In the EMS LP partnership agreement, the Company has agreed to maintain the economic equivalency of the LP exchangeable units and the class B common stock, and the holders of the LP exchangeable units have no general voting rights. The LP exchangeable units, when considered with the class B special voting stock, have the same rights, privileges and characteristics of the Company’s class B common stock. The LP exchangeable units are intended to be economically equivalent to the class B common stock of the Company in that the LP exchangeable units carry the right to vote (by virtue of the class B special voting stock) with the holders of class B common stock as one class, and entitle holders to receive distributions only if the equivalent dividends are declared on the Company’s class B common stock. Accordingly, the Company accounts for the LP exchangeable units as if the LP exchangeable units were shares of its common stock, including reporting the LP exchangeable units in the equity section of the Company’s balance sheet and including the number of outstanding LP exchangeable units in both its basic and diluted earnings per share calculations.

Fair Value Measurement

The Company classifies its financial instruments that are reported at fair value based on a hierarchal framework which ranks the level of market price observability used in measuring financial instruments at fair value. Market price observability is impacted by a number of factors, including the type of instrument and the characteristics specific to the instrument. Instruments with readily available active quoted prices or for which fair value can be measured from actively quoted prices generally will have a higher degree of market price observability and a lesser degree of judgment used in measuring fair value.

Financial instruments measured and reported at fair value are classified and disclosed in one of the following categories:

Level 1—Quoted prices are available in active markets for identical assets or liabilities as of the reporting date. The Company does not adjust the quoted price for these assets or liabilities.

Level 2—Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date, and fair value is determined through the use of models or other valuation methodologies.

Level 3—Pricing inputs are unobservable as of the reporting date and reflect the Company’s own assumptions about the fair value of the asset or liability.

The following table summarizes the valuation of EMSC’s financial instruments as of March 31, 2010 by the above fair value hierarchy levels:

Table of Contents

The Company also estimates the fair value of its fixed rate, senior subordinated notes based on quoted market prices.  The estimated fair value of the senior subordinated notes at March 31, 2010 was approximately $263 million with a carrying value of $250 million.

3.                 Acquisitions

During the three months ended March 31, 2010, the Company made a purchase price allocation adjustment related to the acquisition of the management services entity of Pinnacle Anesthesia Consultants, P.A. and Pinnacle Consultants Mid-Atlantic, L.L.C. (together, the “Pinnacle Acquisition”) which closed in December 2009.  Based on an independent valuation analysis performed, $31.1 million was reclassified from goodwill to intangible assets, and, as a result, an adjustment was also made to amortization expense.

4.                 Accrued Liabilities

Accrued liabilities were as follows at March 31, 2010 and December 31, 2009:

5.              Long-Term Debt

Long-term debt consisted of the following at March 31, 2010 and December 31, 2009:

6.              Derivative Instruments and Hedging Activities

The Company manages its exposure to changes in market interest rates and fuel prices and from time to time uses highly effective derivative instruments to manage well-defined risk exposures.  The Company monitors its positions and the credit ratings of its counterparties and does not anticipate non-performance by the counterparties.  The Company does not use derivative instruments for speculative purposes.

At March 31, 2010, the Company was party to a series of fuel hedge transactions with a major financial institution under one master agreement. Each of the transactions effectively fixes the cost of diesel fuel at prices ranging from $2.88 to $3.15 per gallon. The Company purchases the diesel fuel at the market rate and periodically settles with its counterparty for the

Table of Contents

difference between the national average price for the period published by the Department of Energy and the agreed upon fixed price. The transactions fix the price for a total of 4.4 million gallons, which represents approximately 33% of the Company’s total estimated usage over the hedge period, and are spread over periods from April 2010 through June 2011.  As of March 31, 2010, the Company recorded, as a component of other comprehensive income before applicable tax impacts, an asset associated with the fair value of the fuel hedge in the amount of $0.5 million, compared to $0.2 million as of December 31, 2009. The net additional payments made or received under these hedge agreements resulted in an increase in operating expenses of less than $0.1 million during the three months ended March 31, 2010.

7.              Commitments and Contingencies

Lease Commitments

The Company leases various facilities and equipment under operating lease agreements.

The Company also leases certain vehicles and leasehold improvements under capital leases.  Assets under capital leases are capitalized using inherent interest rates at the inception of each lease. Capital leases are collateralized by the underlying assets.

Forward Purchase Commitment

Beginning in March 2009, AMR entered into a series of forward purchase contracts which fix the price for a portion of its total monthly diesel fuel usage from April 1, 2009 through June 30, 2010. For the three months ending June 30, 2010, the Company is under contract to purchase 50,000 gallons of diesel fuel per month at $2.99 per gallon. These forward purchase contracts represent approximately 6% of the Company’s total monthly diesel fuel usage. Based on the terms of the contracts, the Company has concluded they do not qualify as derivatives. There was no material impact to operating expenses related to these contracts during the three months ended March 31, 2010.

Services

The Company is subject to the Medicare and Medicaid fraud and abuse laws which prohibit, among other things, any false claims, or any bribe, kickback or rebate in return for the referral of Medicare and Medicaid patients. Violation of these prohibitions may result in civil and criminal penalties and exclusion from participation in the Medicare and Medicaid programs. Management has implemented policies and procedures that management believes will assure that the Company is in substantial compliance with these laws and regulations but there can be no assurance the Company will not be found to have violated certain of these laws and regulations. From time to time, the Company receives requests for information from government agencies pursuant to their regulatory or investigational authority. Such requests can include subpoenas or demand letters for documents to assist the government in audits or investigations. The Company is cooperating with the government agencies conducting these investigations and is providing requested information to the government agencies. Other than the proceedings described below, management believes that the outcome of any of these investigations would not have a material adverse effect on the Company.

Other Legal Matters

On December 13, 2005, a lawsuit purporting to be a class action was commenced against AMR in Spokane, Washington in Washington State Court, Spokane County.  The complaint alleges that AMR billed patients and third party payors for transports it conducted between 1998 and 2005 at higher rates than contractually permitted.  The court has certified a class in this case, but the size and membership of the class has not been determined.  At this time, AMR does not believe that any incorrect billings are material in amount.

In December 2006, AMR received a subpoena from the Department of Justice.  The subpoena requested copies of documents for the period from January 2000 through the present.  The subpoena required AMR to produce a broad range of documents relating to the operations of certain AMR affiliates in New York.  The Company produced documents responsive to the subpoena. The government has identified claims for reimbursement that the government believes lack support for the level billed, and invited the Company to respond to the identified areas of concern. The Company reviewed the information provided by the government and provided its response. The Company does not believe the identified claims will result in a material adverse effect on the financial condition or results of operations of EMSC.

Four different lawsuits purporting to be class actions have been filed against AMR and certain subsidiaries in California alleging violations of California wage and hour laws.  On April 16, 2008, Lori Bartoni commenced a suit in the Superior Court for the State of California, County of Alameda; on July 8, 2008, Vaughn Banta filed suit in the Superior Court of the State of California, County of Los Angeles; on January 22, 2009, Laura Karapetian filed suit in the Superior Court of the State of California, County of Los Angeles; and on March 11, 2010, Melanie Aguilar filed suit in Superior Court of the State of California,

10

Table of Contents

County of Los Angeles.  The Banta and Karapetian cases have been coordinated with the Bartoni case in the Superior Court for the State of California, County of Alameda.  At the present time, the courts have not certified classes in any of these cases.  Plaintiffs allege principally that the AMR entities failed to pay overtime charges pursuant to California law, and failed to provide required meal breaks or pay premium compensation for missed meal breaks.  Plaintiffs are seeking to certify the classes and are seeking lost wages, punitive damages, attorneys’ fees and other sanctions permitted under California law for violations of wage hour laws.  The Company is unable at this time to estimate the amount of potential damages, if any.

The Company is involved in other litigation arising in the ordinary course of business.  Management believes the outcome of these legal proceedings will not have a material adverse effect on its financial condition, results of operations or liquidity.

8.              Equity Based Compensation

The Company’s stock options are valued using the Black-Scholes valuation method on the date of grant.  Equity based compensation has been issued under the plans described below.

Equity Option Plan

Under the Company’s Equity Option Plan, key employees were granted options that permit the individuals to purchase class A common shares and vest ratably generally over a period of four years. In addition, certain performance measures must be met for 50% of the options to become exercisable; these performance measures were satisfied during the first quarter of 2009 with respect to the options granted in first quarter of 2005, and in the first quarter of 2010 for the balance of the options under the Equity Option Plan.  As the vesting period for these shares was completed during the first quarter of 2009, the Company did not record a compensation charge for the three months ended March 31, 2010.  A compensation charge of $97 was recorded for the three months ended March 31, 2009.  Options are no longer granted under the Equity Option Plan, but rather under the Company’s Amended and Restated 2007 Long-Term Incentive Plan described below.

Long-Term Incentive Plan

The Company’s original 2007 Long-Term Incentive Plan was approved by stockholders in May 2007 and an Amended and Restated 2007 Long-Term Incentive Plan (the “Plan”) was approved by stockholders in May 2008.  The Plan provides for the grant of long-term incentives, including various equity-based incentives, to those persons with responsibility for the success and growth of the Company and its subsidiaries.  Options granted under the Plan vest and become exercisable ratably over a period of four years from the date of grant and have a maximum term of ten years.  In addition, for options granted under the plan prior to January 1, 2009, certain performance measures were required to be met for 50% of certain of these options to become exercisable; these performance measures were satisfied during the first quarter of 2010.

The Company granted options under the Plan to key employees during the three months ended March 31, 2010.  The options permit employees to purchase an aggregate of 75,000 shares of class A common stock at a weighted average exercise price of $52.06 per share, vest ratably over a period of 4 years from the date of grant and have a maximum term of ten years.

The Company recorded a compensation charge of $979 and $428 during the three months ended March 31, 2010 and 2009, respectively, in connection with the Plan.

Non-Employee Director Compensation Plan

The Non-Employee Director Compensation Plan, approved in May 2007, is available to non-employee directors of the Company, other than the Chair of the Compliance Committee.  Under this plan, eligible directors are granted Restricted Stock Units (“RSUs”) following each annual stockholder meeting with each RSU representing one share of the Company’s class A common stock.  Eligible directors receive a grant of RSUs having a fair market value of $100 on the date of grant based on the closing price of the Company’s class A common stock on the business day immediately preceding the grant date.  The Non-Employee Director Compensation Plan allows directors to defer income from the grant of RSUs, which vest immediately prior to the election of directors at the next annual stockholder meeting.  In connection with this plan, the Company granted 3,018 RSUs per director in 2009.  As described above, RSU grants in 2010 pursuant to this plan will be made following the annual stockholder meeting to be held in the second quarter of 2010.  The Company expensed $125 for the three months ended March 31, 2010 and 2009.

9.              Segment Information

The Company is organized around two separately managed business units: healthcare transportation services and facility-based physician services, which have been identified as operating segments. The healthcare transportation services reportable segment focuses on providing a full range of medical transportation services from basic patient transit to the most advanced

11

Table of Contents

emergency care and pre-hospital assistance. The facility-based physician services reportable segment provides physician services to hospitals primarily for emergency departments and urgent care centers, as well as for hospitalist/inpatient, radiology, teleradiology and anesthesiology services. The Chief Executive Officer has been identified as the chief operating decision maker (“CODM”) as he assesses the performance of the business units and decides how to allocate resources to the business units.

Net income before equity in earnings of unconsolidated subsidiary, income tax expense, interest and other income, realized gain on investments, interest expense, and depreciation and amortization (“Adjusted EBITDA”) is the measure of profit and loss that the CODM uses to assess performance, measure liquidity and make decisions. The accounting policies for reported segments are the same as for the Company as a whole.

A reconciliation of Adjusted EBITDA to cash flows provided by operating activities is as follows:

10.       Guarantors of Debt

EMS LP financed the acquisition of AMR and EmCare in part by issuing $250.0 million principal amount of senior subordinated notes and borrowing $370.2 million under its senior secured credit facility. Its wholly-owned subsidiaries, AMR HoldCo, Inc. and EmCare HoldCo, Inc., are the issuers of the senior subordinated notes and the borrowers under the senior secured credit facility. As part of the transaction, AMR and its subsidiaries became wholly-owned subsidiaries of AMR HoldCo, Inc. and EmCare and its subsidiaries became wholly-owned subsidiaries of EmCare HoldCo, Inc. The senior subordinated notes and the senior secured credit facility include a full, unconditional and joint and several guarantee by EMSC, EMS LP and EMSC’s domestic subsidiaries. The senior subordinated notes and senior secured credit facility do not include a guarantee by the Company’s captive insurance subsidiary. All of the operating income and cash flow of EMSC, EMS LP, AMR HoldCo, Inc. and EmCare HoldCo, Inc. is generated by AMR, EmCare and their subsidiaries. As a result, funds necessary to meet the debt service obligations under the senior secured notes and senior secured credit facility described

above are provided by the distributions or advances from the subsidiary companies, AMR and EmCare. Investments in subsidiary operating companies are accounted for on the equity method. Accordingly, entries necessary to consolidate EMSC, EMS LP, AMR HoldCo, Inc., EmCare HoldCo, Inc. and all of their subsidiaries are reflected in the Eliminations/Adjustments column. Separate complete financial statements of the issuers, EMS LP and subsidiary guarantors would not provide additional material information that would be useful in assessing the financial composition of the issuers, EMS LP or the subsidiary guarantors. The condensed consolidating financial statements for EMSC, EMS LP, the issuers, the guarantors and the non-guarantor are as follows:
