MEDNAX, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

June 30, 2010

(Unaudited)



|1. | Basis of Presentation and New Accounting Pronouncements:
|-- | --------------------------------------------------------

The accompanying unaudited Condensed Consolidated Financial Statements of the Company and the notes thereto presented in
this Form 10-Q have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (SEC) applicable to interim financial statements, and do not include all disclosures required by accounting
principles generally accepted in the United States of America for complete financial statements. In the opinion of management, these financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair
presentation of the results of interim periods. The financial statements include all the accounts of MEDNAX, Inc. and its consolidated subsidiaries (collectively, MDX) together with the accounts of MDXs affiliated professional
associations, corporations and partnerships (the affiliated professional contractors). MDX has contractual management arrangements with its affiliated professional contractors, which are separate legal entities that provide physician
services in certain states and Puerto Rico. The terms MEDNAX and the Company refer collectively to MEDNAX, Inc., its subsidiaries and the affiliated professional contractors.

The consolidated results of operations for the interim periods presented are not necessarily indicative of the results to
be experienced for the entire fiscal year. In addition, the accompanying unaudited Condensed Consolidated Financial Statements and the notes thereto should be read in conjunction with the Consolidated Financial Statements and the notes thereto
included in the Companys most recent Annual Report on Form 10-K (the Form 10-K).

New Accounting
Pronouncements

Effective January 1, 2010, the Company adopted the provisions of new accounting
guidance related to variable interest entities. The new guidance amended the consolidation accounting model and included new disclosure requirements for certain types of variable interest entities. The adoption of the new provisions did not have an
impact on the Companys Condensed Consolidated Financial Statements.

In January 2010, the accounting
guidance related to fair value measurements was amended. The amendment requires disclosure of transfers of assets and liabilities into and out of Level 1 and Level 2 of the fair value hierarchy, including the reasons and the timing of the
transfers and disclosure of valuation techniques and inputs for assets and liabilities within Level 2 and Level 3 of the fair value hierarchy. Additionally, the guidance requires expanded disclosure about assets and liabilities within Level 3.
The new guidance became effective for the Company on January 1, 2010, except for the new guidance related to the expanded Level 3 disclosure, which is effective for periods beginning after December 15, 2010. The Company did not have any
transfers in or out of Level 1 and Level 2 fair value measurements during the six months ended June 30, 2010; therefore, the adoption of the new guidance did not have any impact on the Companys Condensed Consolidated Financial Statements.



|2. | Cash Equivalents and Investments:
|-- | ---------------------------------

Certain cash equivalents carried by the Company are subject to the provisions of the accounting guidance for fair value
measurements. Under this guidance, the Company is required to measure the fair value of its financial assets using a three-tier fair value hierarchy. Based on this hierarchy, the Company determined the fair value of its money market funds using
quoted market prices, a Level 1 or an observable input as defined under the accounting guidance. As of June 30, 2010 and December 31, 2009, the Companys cash equivalents consisted entirely of money market funds with a fair value of
$22.6 million and $20.2 million, respectively.

Investments consist of municipal debt securities, federal home
loan securities and certificates of deposit. Investments with remaining maturities of less than one year are classified as short-term investments. Investments classified as long-term have maturities of two to five years.

The Company intends and has the ability to hold its held-to-maturity securities to maturity, and therefore carries such
investments at amortized cost in accordance with the provisions of the accounting guidance for investments in debt and equity securities. Held-to-maturity securities are not subject to the requirements of the accounting guidance for fair value
measurements.

|3. | Fair Value of Financial Instruments:
|-- | ------------------------------------

In accordance with the accounting guidance for fair value measurements and disclosures, the Company carries its money
market funds and the cash surrender value of life insurance related to its deferred compensation arrangements at fair value. Under this guidance, the fair value of these instruments is determined using a three-tier fair value hierarchy. Based on
this hierarchy, the Company determined the fair value of its money market funds and the cash surrender value of life insurance using quoted market prices, a Level 1 or an observable input as defined under the accounting guidance for fair value
measurements. The investments underlying the cash surrender value of life insurance consist primarily of exchange-traded equity securities and mutual funds with quoted prices in active markets. At June 30, 2010, the Companys money market
funds and the cash surrender value of life insurance had carrying amounts of $22.6 million and $10.5 million, respectively. At December 31, 2009, the Companys money market funds and the cash surrender value of life insurance had carrying
amounts of $20.2 million and $10.7 million, respectively.

The carrying amounts of cash equivalents, short-term
investments, accounts receivable and accounts payable and accrued expenses approximate fair value due to the short maturities of the respective instruments. The carrying value of long-term investments, long-term debt and capital lease obligations
approximates fair value.

|5. | Business Acquisitions:
|-- | ----------------------

During the six months ended June 30, 2010, the Company completed the acquisition of seven physician group practices
for total consideration of $62.5 million, consisting of $53.5 million in cash and $9.0 million of contingent consideration. In connection with these acquisitions, the Company recorded goodwill of $59.8 million, other intangible assets consisting
primarily of physician and hospital agreements of $2.3 million and fixed assets of $0.4 million. These acquisitions expand the Companys national network of physician practices. The Company expects to improve the results of these physician
practices through improved managed care contracting, improved collections, identification of growth initiatives, as well as, operating and cost savings based upon the significant infrastructure it has developed.

The contingent consideration of $9.0 million recorded during the six months ended June 30, 2010 is related to an
agreement to pay additional amounts based on the achievement of certain performance measures for up to five years ending after the acquisition date. The accrued contingent consideration related to this acquisition was recorded at acquisition-date
fair value using the income approach with assumed discount rates ranging from 3.0% to 6.0% over the applicable terms and an assumed payment probability of 100% for each of the applicable years. The range of the undiscounted amount the Company could
pay under this contingent consideration agreement is between $0 and $10.5 million.

During the six months ended
June 30, 2010, the Company paid approximately $6.6 million for contingent consideration related to certain prior-period acquisitions, of which $1.6 million was accrued as of December 31, 2009.

##### Table of Contents

In addition, during the six months ended June 30, 2010, the Company accrued approximately $2.3 million of contingent consideration related to a prior year acquisition for which the earnings
objectives were met during the second quarter of 2010. The Company expects that all of the approximately $67.7 million of goodwill recorded during the six months ended June 30, 2010 will be deductible for tax purposes.

The results of operations of the seven practices acquired during the six months ended June 30, 2010 have been
included in the Companys Condensed Consolidated Financial Statements from their respective dates of acquisition. The following unaudited pro forma information combines the consolidated results of operations of the Company and the acquisitions

|6. | Accounts Payable and Accrued Expenses:

Accounts payable and accrued expenses consist of the following (in thousands):



|                                     |  |               |         |                   |   |

The net decrease in accrued salaries
and bonuses of $71.3 million, from $144.8 million at December 31, 2009 to $73.5 million at June 30, 2010, is primarily due to the payment of performance-based incentive compensation during the first quarter of 2010, partially offset by
performance-based incentive compensation accrued during the six months ended June 30, 2010. A majority of the Companys payments for performance-based incentive compensation is paid annually in the first quarter of each year.



|7. | Uncertain Tax Positions
|-- | -----------------------

As of June 30, 2010 and December 31, 2009, the Companys liability for uncertain tax positions, excluding
interest and penalties, was $50.3 million and $49.4 million, respectively.

The Companys liability for
uncertain tax positions could be reduced over the next 12 months by an amount of up to $11.0 million, excluding interest and penalties, due to potential settlements with taxing authorities regarding certain matters that are currently under review
and the expiration of statutes of limitation. The Company also anticipates that it is reasonably possible that approximately $29.5 million of the liability for uncertain tax positions related to certain temporary differences could be reclassified to
deferred taxes payable over the next 12 months. In addition, the Companys liability for uncertain tax positions could be increased over the next 12 months by approximately $1.0 million, excluding accrued interest.

|8. | Common and Common Equivalent Shares:
|-- | ------------------------------------

Basic net income per share is calculated by dividing net income by the weighted average number of common shares
outstanding during the period. Diluted net income per share is calculated by dividing net income by the weighted average number of common and potential common shares outstanding during the applicable period. Potential common shares consist of
outstanding options and non-vested restricted and deferred stock calculated using the treasury stock method. Under the treasury stock method, the Company calculates the assumed excess tax benefits related to the potential exercise or vesting of its
stock-based awards using the difference between the average market price for the applicable period less the option price, if any, and the fair value of the stock-based award on the date of grant multiplied by the applicable tax rate.

The calculation of shares used in the basic and diluted net income per share calculation for the three and six months
ended June 30, 2010 and 2009 is as follows (in thousands):

|9. | Stock Incentive Plans and Stock Purchase Plans:
|-- | -----------------------------------------------

The terms of the Companys 2008 Incentive Compensation Plan (the 2008 Incentive Plan) provide for grants
of stock options, stock appreciation rights, restricted stock, deferred stock, and other stock-related awards and performance awards that may be settled in cash, stock or other property. As provided in the 2008 Incentive Plan, no additional grants
can be made from the Companys prior incentive plans, except that new awards will be permitted under the 2004 Incentive Compensation Plan (the 2004 Incentive Plan) to the extent that shares previously granted under the 2004
Incentive Plan are forfeited, expire or terminate. Under the 2008 Incentive Plan, a total of six million shares were available for the granting of awards, inclusive of the number of shares remaining available for grant under the 2004 Incentive Plan
as of May 23, 2008. To date, the only equity awards made by the Company under the 2008 Incentive Plan are for stock options, restricted stock and deferred stock. Collectively, the Companys prior incentive plans and the 2008 Incentive Plan
are referred to as the Stock Incentive Plans.

Under the 2008 Incentive Plan, options to purchase shares of
common stock may be granted at a price not less than the fair market value of the shares on the date of grant. The options must be exercised within 10 years from the date of grant and generally become exercisable on a pro rata basis over a
three-year period from the date of grant. Restricted stock awards generally vest over periods of three years upon the fulfillment of specified service-based conditions and in certain instances performance-based conditions. Deferred stock awards vest
on a cliff basis over a term of five years upon the fulfillment of specified service-based and performance-based conditions. The Company recognizes compensation expense related to its restricted stock and deferred stock awards ratably over the
corresponding vesting periods. During the six months ended June 30, 2010, the Company granted 431,720 shares of restricted stock and 60,747 stock options to its employees under the Stock Incentive Plans. At June 30, 2010, the Company had
approximately 2.2 million shares available for future grants and awards under the Stock Incentive Plans.

In September 2008, the Companys shareholders approved an amendment to the Companys 1996 Non-Qualified Employee
Stock Purchase Plan (the Non-Qualified Plan) to increase the number of shares issuable under the Non-Qualified Plan from 1.5 million to 2.5 million shares. The approved amendment also expanded participation in the Non-Qualified
Plan to all employees who formerly participated in the 1996 Qualified Employee Stock Purchase Plan, which was terminated in August 2008. Under the Non-Qualified Plan, employees are permitted to purchase the Companys common stock at 85% of
market value on January 1st, April 1st, July 1st and October 1st of each year. During the six months ended June 30, 2010, 64,131 shares were issued under the Non-Qualified Plan. At June 30, 2010, the Company
had approximately 738,000 shares reserved for issuance under the Non-Qualified Plan.

During the three and six months ended June 30, 2010 and 2009, the
Company recognized approximately $6.3 million and $12.4 million, and $5.7 million and $11.4 million, respectively, of stock-based compensation expense related to the Stock Incentive Plans and the Non-Qualified Plan. The excess tax benefit recognized
in additional paid-in capital related to the exercise of stock options and the vesting of restricted stock for the three and six months ended June 30, 2010 was approximately $1.8 million and $2.2 million, respectively.



|10. | Commitments and Contingencies:
|--- | ------------------------------

In July 2007, the Audit Committee of the Companys Board of Directors concluded a comprehensive review of the
Companys historical practices related to the granting of stock options. In connection with the review, the Company had discussions with the U.S. Attorneys office for the Southern District of Florida concerning the matters covered by the
review and, in response to a subpoena received in December 2007, provided the office with various documents and information related to the Companys stock option granting practices. Although the Company intends to continue full cooperation with
the U.S. Attorneys office, it cannot predict the outcome of this matter.

In September 2006, the Company
completed a final settlement agreement with the Department of Justice and a relator who initiated a qui tam complaint against the Company relating to its billing practices for services reimbursed by Medicaid, the Federal Employees Health
Benefit program, and the United States Department of Defenses TRICARE program for military dependents and retirees (Federal Settlement Agreement). In February 2007, the Company completed separate state settlement agreements with
each state Medicaid program involved in the settlement (the State Settlement Agreements). Under the terms of the Federal Settlement Agreement and State Settlement Agreements, the Company paid $25.1 million to the federal government and
participating state Medicaid programs in connection with its billing for neonatal services provided from January 1996 through December 1999.

As part of the Federal Settlement Agreement, the Company is under a five-year Corporate Integrity Agreement with the
Office of Inspector General of the Department of Health and Human Services (the OIG). The Corporate Integrity Agreement acknowledges the existence of the Companys comprehensive Compliance Plan, which provides for policies and
procedures aimed at promoting the Companys adherence with FHC Program requirements and requires the Company to maintain the Compliance Plan in full operation for the term of the Corporate Integrity Agreement. In addition, the Corporate
Integrity Agreement requires, among other things, that the Company must comply with the following integrity obligations during the term of the Corporate Integrity Agreement:



| |  |  | maintaining a Chief Compliance Officer and Compliance Committee to administer compliance with FHC Program requirements, the Compliance Plan and the
Corporate Integrity Agreement;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | maintaining the Code of Conduct for the Companys officers, directors, employees, contractors, subcontractors, agents, or other persons who
provide patient care items or services (the Covered Persons);
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | maintaining the written policies and procedures regarding the operation of the Compliance Plan and the Companys compliance with FHC Program
requirements;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | providing general compliance training to the Covered Persons as well as specific training to the Covered Persons who perform coding functions relating
to claims for reimbursement from any FHC Program;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | engaging an independent review organization to perform annual reviews of samples of claims from multiple hospital units to assist the Company in
assessing and evaluating its coding, billing, and claims-submission practices;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | maintaining the Disclosure Program that includes a mechanism to enable individuals to confidentially disclose issues or questions believed by the
individual to be a potential violation of criminal, civil, or administrative laws;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | not hiring or, if employed, removing from the Companys business operations which are related to or compensated, in whole or part, by FHC
Programs, persons (i) convicted of a criminal offense related to the provision of healthcare items or services or (ii) ineligible to participate in FHC Programs or Federal procurement or non-procurement programs;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | notifying the OIG of (i) new investigations or legal proceedings by a governmental entity or its agents involving an allegation that the Company
has committed a crime or has engaged in fraudulent activities, (ii) matters that a reasonable person would consider a probable violation of criminal, civil or administrative laws applicable to any FHC Program for which penalties or exclusion
may be imposed, and (iii) the purchase, sale, closure, establishment, or relocation of any facility furnishing items or services that are reimbursed under FHC Programs;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | reporting and returning overpayments received from FHC Programs;
| | - |  | ----------------------------------------------------------------



| |  |  | submitting reports to the OIG regarding the Companys compliance with the Corporate Integrity Agreement; and
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | maintaining for inspection, for a period of six years from the effective date, all documents and records relating to reimbursement from the FHC
Programs and compliance with the Corporate Integrity Agreement.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Failure to comply with the
Companys duties under the Corporate Integrity Agreement could result in substantial monetary penalties and in the case of a material breach, could even result in the Company being excluded from participating in FHC Programs. Management
believes that the Company was in compliance with the Corporate Integrity Agreement as of June 30, 2010.

The Company expects that additional audits, inquiries and investigations from government authorities and agencies will
continue to occur in the ordinary course of business. Such audits, inquiries and investigations and their ultimate resolutions, individually or in the aggregate, could have a material adverse effect on the Companys business, financial
condition, results of operations, cash flows, and the trading price of its common stock.

In the ordinary
course of business, the Company becomes involved in pending and threatened legal actions and proceedings, most of which involve claims of medical malpractice related to medical services provided by the Companys affiliated physicians. The
Companys contracts with hospitals generally require the Company to indemnify them and their affiliates for losses resulting from the negligence of the Companys affiliated physicians. The Company may also become subject to other lawsuits
which could involve large claims and significant defense costs. The Company believes, based upon a review of pending actions and proceedings, that the outcome of such legal actions and proceedings will not have a material adverse effect on its
business, financial condition or results of operations. The outcome of such actions and proceedings, however, cannot be predicted with certainty and an unfavorable resolution of one or more of them could have a material adverse effect on the
Companys business, financial condition, results of operations, cash flows, and the trading price of its common stock.

Although the Company currently maintains liability insurance coverage intended to cover professional liability and certain
other claims, the Company cannot assure that its insurance coverage will be adequate to cover liabilities arising out of claims asserted against it in the future where the outcomes of such claims are unfavorable. With respect to professional
liability risk, the Company generally self-insures a portion of this risk through its wholly owned captive insurance subsidiary. Liabilities in excess of the Companys insurance coverage, including coverage for professional liability and
certain other claims, could have a material adverse effect on the Companys business, financial condition and results of operations.

Item 2. Managements Discussion and Analysis of Financial Condition and
Results of Operations

The following discussion highlights the principal factors that have affected our financial condition
and results of operations, as well as our liquidity and capital resources, for the periods described. This discussion should be read in conjunction with the unaudited Condensed Consolidated Financial Statements and the notes thereto included in this
Quarterly Report. In addition, reference is made to our audited consolidated financial statements and notes thereto and related Managements Discussion and Analysis of Financial Condition and Results of Operations included in our most recent
Annual Report on Form 10-K. As used in this Quarterly Report, the terms MEDNAX, the Company, we, us and our refer to MEDNAX, Inc. and its consolidated subsidiaries (collectively
MDX), together with MDXs affiliated professional associations, corporations and partnerships (affiliated professional contractors). Certain subsidiaries of MDX have contracts with our affiliated professional
contractors, which are separate legal entities that provide physician services in certain states and Puerto Rico.

Overview

In March 2010, the Patient Protection and Affordable Care Act, as amended by a subsequent reconciliation bill (as amended, the
Healthcare Reform Act), was enacted. The Healthcare Reform Act contains a number of provisions that could affect us over the next several years. These provisions include establishing health insurance exchanges to facilitate the purchase
of qualified health plans, expanding Medicaid eligibility, subsidizing insurance premiums and creating incentives for businesses to provide healthcare benefits. Other provisions contain changes to healthcare fraud and abuse laws and expand the scope
of the Federal False Claims Act.

The Healthcare Reform Act contains numerous other measures that could also affect us. For
example, payment modifiers are to be developed that will differentiate payments to physicians under federal healthcare programs based on quality of care. In addition, other provisions authorize voluntary demonstration projects relating to the
bundling of payments for episodes of hospital care and the sharing of cost savings achieved by providers organized as accountable care organizations under the Medicare program.

The Healthcare Reform Act, however, did not address the mechanism by which physician fees are set under Medicare. A scheduled Medicare
fee reduction of approximately 21% became effective June 1, 2010. However, on June 25, 2010 Congress temporarily reversed the reduction, retroactive to June 1, 2010, and raised the Medicare fee by approximately 2%. If Congress does
not take further action, the Medicare fee schedule will be reduced by approximately 23% effective December 1, 2010.

Healthcare is an area of rapid regulatory change. Changes in the laws and regulations and new interpretations of existing laws and
regulations may further affect reimbursement amounts paid by federal, state and other third-party payors. We cannot predict with any assurance the ultimate effect of the Healthcare Reform Act or the scheduled fee reduction on our Company, nor can we
provide any assurance that they will not have a material adverse effect on our business, results of operations, financial condition or cash flows.

The United States is continuing to experience an economic slowdown. As a result of the slowdown, the number of unemployed workers remains
significant, and the capital and credit markets continue to be impacted. During the first half of 2010, our business continued to be affected by a shift toward government-sponsored programs. There could be additional shifts toward
government-sponsored programs and declines in patient volumes if economic conditions in the United States do not improve or deteriorate further. Payments received from government-sponsored programs are substantially less than payments received from
commercial payors for equivalent services. As a consequence of the economic slowdown, many states are continuing to experience lower than anticipated revenue and continue to face significant budget shortfalls. These shortfalls could lead to reduced
or delayed funding for state Medicaid programs and, in turn, reduced or delayed reimbursement for physician services.

During
the six months ended June 30, 2010, we completed the acquisition of seven physician group practices consisting of six neonatal practices and one maternal-fetal medicine practice. During the six months ended June 30, 2009, we completed the
acquisition of six physician practices consisting of four neonatal practices, one maternal-fetal practice and one pediatric cardiology practice. Based on past results, we expect that we can improve the results of these practices through improved
managed care contracting, improved collections, identification of growth initiatives, as well as operating and cost savings, based upon the significant infrastructure we have developed.

Our results of operations for the six months ended June 30, 2010 and 2009 include the results of operations for these physician
group practices from their respective dates of acquisition and therefore are not comparable in some respects.

The following
discussion contains forward-looking statements. Please see the Companys most recent Annual Report on Form 10-K, including Item 1A, Risk Factors, for a discussion of the uncertainties, risks and assumptions associated with these
forward-looking statements. In addition, please see Caution Concerning Forward-Looking Statements below.

Results of Operations

Three Months Ended June 30, 2010 as Compared to Three Months Ended June 30, 2009

Our net patient service revenue increased $29.3 million, or 9.2%, to $349.1 million for the three months ended June 30, 2010, as
compared to $319.8 million for the same period in 2009. Of this $29.3 million increase, $22.2 million, or 75.8%, was attributable to revenue generated from acquisitions completed after March 31, 2009. Same-unit net patient service revenue
increased $7.1 million, or 2.3%, for the three months ended June 30, 2010. The change in same-unit net patient service revenue was the net result of increased revenue of approximately $8.5 million, or 2.7%, related to pricing and reimbursement
factors partially offset by a net decrease of $1.4 million, or 0.4%, from lower overall patient service volumes across our specialties. The net increase in revenue of $8.5 million related to pricing and reimbursement factors was primarily due to
improved managed care contracting and the flow through of revenue from modest price increases partially offset by a decrease in revenue caused by an increase in the percentage of our patients being enrolled in government-sponsored programs. Payments
received from government-sponsored programs are substantially less than payments received from commercial insurance payors for equivalent services. The net decrease in revenue of $1.4 million from lower patient service volumes includes a decrease of
$0.3 million from a 0.1% decline in neonatal intensive care unit patient days, a decrease of $1.2 million from volume declines in our maternal-fetal medicine subspecialty, our anesthesiology specialty and other services, partially offset by an
increase of $0.1 million from volume growth in our pediatric cardiology subspecialty. Same units are those units at which we provided services for the entire current period and the entire comparable period.

Practice salaries and benefits increased $17.0 million, or 8.9%, to $208.8 million for the three months ended June 30, 2010, as
compared to $191.8 million for the same period in 2009. This $17.0 million increase was primarily attributable to increased costs associated with new physicians and other staff to support acquisition-related growth and growth at existing units,
partially offset by a decrease in incentive compensation based on physician-practice operational results.

Practice supplies
and other operating expenses increased $1.3 million, or 9.9%, to $14.1 million for the three months ended June 30, 2010, as compared to $12.8 million for the same period in 2009. The increase was attributable to practice supply and other costs
of $0.7 million related to hospital-based acquisitions, rent, medical supply and other costs of $0.5 million related to our office-based acquisitions, and $0.1 million in practice supply and other costs at our existing units.

General and administrative expenses include all billing and collection functions and all other salaries, benefits, supplies and operating
expenses not specifically related to the day-to-day operations of our physician group practices. General and administrative expenses increased $2.9 million, or 7.9%, to $39.2 million for the three months ended June 30, 2010, as compared to
$36.3 million for the same period in 2009. This increase of $2.9 million is attributable to salaries, benefits and other general and administrative costs related to the overall growth of the Company. General and administrative expenses as a
percentage of net patient service revenue decreased to 11.2% for the three months ended June 30, 2010, as compared to 11.3% for the three months ended June 30, 2009. General and administrative expense grew at a rate slower than the rate of
revenue due to continued administrative efficiencies that include the integration of billing services related to our anesthesia practices, partially offset by the timing of certain annual expenses.

Depreciation and amortization expense increased by $0.8 million, or 19.6%, to $5.0 million for the three months ended June 30, 2010,
as compared to $4.2 million for the same period in 2009. This increase was attributable to the amortization of intangible assets related to acquisitions and the depreciation of fixed asset additions.

Income from operations increased $7.3 million, or 9.8%, to $82.1 million for the three months ended June 30, 2010, as compared to
$74.8 million for the same period in 2009. Our operating margin increased to 23.5% for the three months ended June 30, 2010, as compared to 23.4% for the same period in 2009. This increase of 14 basis points is primarily due to acquisition
growth and general and administrative expense management, partially offset by the timing of certain expenses.

We recorded net
interest expense of $0.9 million for the three months ended June 30, 2010, as compared to $0.4 million for the same period in 2009. The increase in net interest expense was primarily due to accretion related to our contingent consideration
liabilities and other interest charges, partially offset by a decrease in interest expense due to lower average borrowings under our $350 million revolving credit facility (Line of Credit). Interest expense for the three months ended
June 30, 2010 and 2009, consisted primarily of interest charges, commitment fees and amortized debt costs associated with our Line of Credit.

Our effective income tax rate was 39.3% for the three months ended June 30, 2010, as compared to 41.9% for the same period in 2009.
The rate for the three months ended June 30, 2009 included the recognition of a non-deductible loss and an increase in reserves related to uncertain tax positions.

Net income increased by 14.2% to $49.4 million for the three months ended June 30,
2010, as compared to $43.2 million for the same period in 2009.

Diluted net income per common and common equivalent share was
$1.04 on weighted average shares outstanding of 47.5 million for the three months ended June 30, 2010, as compared to $0.93 on weighted average shares outstanding of 46.3 million for the same period in 2009.

Six Months Ended June 30, 2010 as Compared to Six Months Ended June 30, 2009

Our net patient service revenue increased $58.3 million, or 9.4%, to $682.0 million for the six months ended June 30, 2010, as
compared to $623.7 million for the same period in 2009. Of this $58.3 million increase, $44.3 million, or 76.0%, was attributable to revenue generated from acquisitions completed after December 31, 2008. Same-unit net patient service revenue
increased $14.0 million, or 2.3%, for the six months ended June 30, 2010. The change in same-unit net patient service revenue was the net result of increased revenue of approximately $16.4 million, or 2.7%, related to pricing and reimbursement
factors partially offset by a net decrease of $2.4 million, or 0.4%, from lower overall patient service volumes across our specialties. The net increase in revenue of $16.4 million related to pricing and reimbursement factors was primarily due to
improved managed care contracting and the flow through of revenue from modest price increases partially offset by a decrease in revenue caused by an increase in the percentage of our patients being enrolled in government-sponsored programs. Payments
received from government-sponsored programs are substantially less than payments received from commercial insurance payors for equivalent services. The net decrease in revenue of $2.4 million from lower patient service volumes includes a decrease of
$1.4 million from a 0.4% decline in neonatal intensive care unit patient days, a decrease of $2.0 million from volume declines in our maternal-fetal medicine subspecialty, and a slight decline in other services, partially offset by increases of $1.2
million from volume growth in pediatric cardiology and anesthesiology. Same units are those units at which we provided services for the entire current period and the entire comparable period.

Practice salaries and benefits increased $36.4 million, or 9.4%, to $422.2 million for the six months ended June 30, 2010, as
compared to $385.8 million for the same period in 2009. This $36.4 million increase was primarily attributable to increased costs associated with new physicians and other staff to support acquisition-related growth and growth at existing units
partially offset by a decrease in incentive compensation based on physician-practice operational results.

Practice supplies
and other operating expenses increased $1.8 million, or 6.8%, to $27.2 million for the six months ended June 30, 2010, as compared to $25.4 million for the same period in 2009. The increase was attributable to practice supply and other costs of
$1.3 million related to hospital-based acquisitions, rent, medical supply and other costs of $0.7 million related to our office-based acquisitions, partially offset by a decrease of $0.2 million in practice supply and other costs at our existing
units.

General and administrative expenses include all billing and collection functions and all other salaries, benefits,
supplies and operating expenses not specifically related to the day-to-day operations of our physician group practices. General and administrative expenses increased $4.4 million, or 5.9%, to $77.3 million for the six months ended June 30,
2010, as compared to $72.9 million for the same period in 2009. This increase of $4.4 million is attributable to salaries, benefits and other general and administrative costs related to the overall growth of the Company. General and administrative
expenses as a percentage of net patient service revenue decreased to 11.3% for the six months ended June 30, 2010 from 11.7% for the six months ended June 30, 2009. General and administrative expense growth was at a rate considerably
slower than the rate of revenue growth due to our ongoing expense management efforts as well as administrative efficiencies related to our anesthesiology practices.

Depreciation and amortization expense increased by $1.6 million, or 20.1%, to $9.8 million for the six months ended June 30, 2010,
as compared to $8.2 million for the same period in 2009. This increase was attributable to the amortization of intangible assets related to acquisitions and the depreciation of fixed asset additions.

Income from operations increased $14.3 million, or 10.8%, to $145.7 million for the six months ended June 30, 2010, as compared to
$131.4 million for the same period in 2009. Our operating margin increased to 21.4% for the six months ended June 30, 2010, as compared to 21.1% for the same period in 2009. This increase of 29 basis points is primarily due to acquisition
growth and general and administrative expense management.

We recorded net interest expense of $1.2 million for the six months
ended June 30, 2010, as compared to $1.0 million for the same period in 2009. The increase in net interest expense was primarily due to accretion related to our contingent consideration liabilities combined with a lower rate of return on our
investments, partially offset by a decrease in interest expense due to lower average borrowings under our $350 million Line of Credit. Interest expense for the six months ended June 30, 2010 and 2009, consisted primarily of interest charges,
commitment fees and amortized debt costs associated with our Line of Credit.

##### Table of Contents

Our effective income tax rate was 39.4% for the six months ended June 30, 2010, as
compared to 40.8% for the same period in 2009. The rate for the six months ended June 30, 2009 included the recognition of a non-deductible loss and increase in reserve requirements related to uncertain tax positions.

Net income increased by 13.4% to $87.6 million for the six months ended June 30, 2010, as compared to $77.3 million for the same
period in 2009.

Diluted net income per common and common equivalent share was $1.85 on weighted average shares outstanding of
47.4 million for the six months ended June 30, 2010, as compared to $1.68 on weighted average shares outstanding of 46.1 million for the same period in 2009.

Liquidity and Capital Resources

As of June 30, 2010, we had $26.1 million of cash and cash equivalents on hand as compared to $26.5 million at December 31,
2009. In addition, we had working capital of $13.5 million at June 30, 2010, an increase of $67.5 million from a working capital deficit of $54.0 million at December 31, 2009. This net increase in working capital is primarily due to
year-to-date earnings, proceeds from the issuance of common stock under our stock incentive and stock purchase plans and borrowings under our Line of Credit, partially offset by the use of funds for practice acquisition payments.

Our net cash provided from operating activities was $50.1 million for the six months ended June 30, 2010, as compared to net cash
provided from operating activities of $61.7 million for the same period in 2009. This $11.6 million net decrease in our cash flow provided from operating activities for the six months ended June 30, 2010 is primarily due to: (i) a net
decrease in cash flow from operations related to changes in the components of our accounts payable and accrued expenses, consisting primarily of annual incentive compensation payments; and (ii) a reduction in cash flow from operations related
to higher accounts receivable balances from higher net patient service revenue recorded during the six months ended June 30, 2010; partially offset by (iii) a net improvement in cash flow related to changes in our income tax liabilities,
resulting primarily from lower estimated tax payments and (iv) improved operating results.

During the six months ended
June 30, 2010, accounts receivable increased by $14.5 million, as compared to an increase of $1.0 million for the same period in 2009. The net increase in accounts receivable for the six months ended June 30, 2010 is primarily due to
higher net patient service revenue recorded during the period and a slight increase in days sales outstanding (DSO).

Our accounts receivable are principally due from managed care payors, government payors, and other third-party insurance payors. We track
our collections from these sources, monitor the age of our accounts receivable, and make all reasonable efforts to collect outstanding accounts receivable through our systems, processes and personnel at our corporate and regional billing and
collection offices. We use customary collection practices, including the use of outside collection agencies, for accounts receivable due from private pay patients when appropriate. Almost all of our accounts receivable adjustments consist of
contractual adjustments due to the difference between gross amounts billed and the amounts allowed by our payors. Any amounts written off related to private pay patients are based on the specific facts and circumstances related to each individual
patient account.

DSO is one of the key factors that we use to evaluate the condition of our accounts receivable and the
related allowances for contractual adjustments and uncollectibles. DSO reflects the timeliness of cash collections on billed revenue and the level of reserves on outstanding accounts receivable. Our DSO was 46.7 days at June 30, 2010 as
compared to 45.4 days at December 31, 2009.

During the six months ended June 30, 2010, cash used in operating
activities related to accounts payable and accrued expenses was $70.5 million, compared to $30.8 million for the same period in 2009. The net increase in cash used of $39.7 million related to the components of our accounts payable and accrued
expenses is primarily due to an increase in our annual payments due under our performance-based incentive compensation program. A majority of our payments for performance-based compensation are paid annually in the first quarter of each year.

During the six months ended June 30, 2010, our net cash used in investing activities of $66.9 million included physician
practice acquisition payments and contingent purchase price payments of $58.5 million, capital expenditures of $7.2 million, and net purchases of $1.1 million related to the purchase and maturity of investments. Our acquisition payments were
primarily related to the purchase of six neonatal physician practices and one maternal-fetal medicine practice. Our capital expenditures were for medical equipment, software, leasehold improvements, computer and office equipment, furniture and
fixtures and other improvements at our office-based practices and our corporate and regional offices.

##### Table of Contents

During the six months ended June 30, 2010, our net cash provided from financing
activities of $16.4 million consisted primarily of net borrowings under our Line of Credit of $8.0 million and proceeds from the exercise of employee stock options and the issuance of common stock under our stock purchase plans of $8.0 million,
partially offset by a $1.6 million payment of a contingent consideration liability. Under the current accounting guidance for business combinations, payments of contingent consideration liabilities related to acquisitions completed after
January 1, 2009 are presented as cash flows from financing activities. Payments of contingent consideration liabilities related to acquisitions completed prior to January 1, 2009 are presented as cash flows from investing activities.

Our $350 million Line of Credit is guaranteed by substantially all of our subsidiaries and includes a $50 million
sub-facility for the issuance of letters of credit and a $25 million sub-facility for swingline loans. In addition, our Line of Credit may be increased to $400 million subject to the satisfaction of specified conditions. At our option, our Line of
Credit (other than swingline loans) bears interest at (1) the alternate base rate, which is defined as the higher of (i) the Federal Funds Rate plus one half of 1.0% and (ii) the Wachovia Bank, N.A prime rate or (2) the LIBOR
rate, plus, in either case, an applicable margin rate of up to 1.5% based on our consolidated leverage ratio. The Line of Credit is also subject to facility fees based on applicable rates defined in the agreement and the aggregate commitments,
regardless of usage. Swingline loans bear interest at the alternate base rate plus the applicable margin. Our Line of Credit matures on September 3, 2013. We are subject to certain covenants and restrictions specified in our Line of Credit,
including covenants that require us to maintain a minimum fixed charge coverage ratio and to not exceed a specified consolidated leverage ratio, to comply with laws, and restrict us from paying dividends and making certain other distributions, as
specified therein. Failure to comply with these covenants would constitute an event of default under our Line of Credit, notwithstanding our ability to meet our debt service obligations. Our Line of Credit includes various customary remedies for the
lenders following an event of default.

At June 30, 2010, we had an outstanding principal balance of $58.0 million on our
Line of Credit. We also had outstanding letters of credit associated with our professional liability insurance program of $5.9 million which reduced the amount available on our Line of Credit to $286.1 million at June 30, 2010. At June 30,
2010, we believe we were in compliance, in all material respects, with the financial covenants and other restrictions applicable to us under our Line of Credit. Based on our current expectations, we believe we will be in compliance with these
covenants throughout 2010.

We maintain professional liability insurance policies with third-party insurers, subject to
self-insured retention, exclusions and other restrictions. We self-insure our liabilities to pay self-insured retention amounts under our professional liability insurance coverage through a wholly owned captive insurance subsidiary. We record
liabilities for self-insured amounts and claims incurred but not reported based on an actuarial valuation using historical loss information, claim emergence patterns and various actuarial assumptions. Our total liability related to professional
liability risks at June 30, 2010 was $114.1 million.

We anticipate that funds generated from operations, together with
our current cash on hand and funds available under our Line of Credit, will be sufficient to finance our working capital requirements, fund anticipated acquisitions and capital expenditures, and meet our contractual obligations for at least the next
12 months.

Caution Concerning Forward-Looking Statements

Certain information included or incorporated by reference in this Quarterly Report may be deemed to be forward-looking statements.
Forward-looking statements may include, but are not limited to, statements relating to our objectives, plans and strategies, and all statements (other than statements of historical facts) that address activities, events or developments that we
intend, expect, project, believe or anticipate will or may occur in the future are forward-looking statements. These statements are often characterized by terminology such as believe, hope, may,
anticipate, should, intend, plan, will, expect, estimate, project, positioned, strategy and similar expressions and are based on
assumptions and assessments made by our management in light of their experience and their perception of historical trends, current conditions, expected future developments and other factors they believe to be appropriate. Any forward-looking
statements in this Quarterly Report are made as of the date hereof, and we undertake no duty to update or revise any such statements, whether as a result of new information, future events or otherwise. Forward-looking statements are not guarantees
of future performance and are subject to risks and uncertainties. Important factors that could cause actual results, developments and business decisions to differ materially from forward-looking statements are described in the Companys most
recent Annual Report on Form 10-K, including the section entitled Risk Factors.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Our Line of Credit is subject to market risk and interest rate changes. Our Line of Credit bears interest at (1) the
alternate base rate, which is defined as the higher of (i) the Federal Funds Rate plus one half of 1.0% and (ii) the Wachovia Bank, N.A. prime rate or (2) the LIBOR rate, plus, in either case, an applicable margin rate of up to 1.5%
based on our consolidated leverage ratio. The outstanding principal balance on our Line of Credit was $58.0 million at June 30, 2010. Considering the total outstanding balance of $58.0 million, a 1.0% change in interest rates would result in an
impact to income before taxes of approximately $0.6 million per year.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of
1934, as amended) that are designed to provide reasonable assurance that information required to be disclosed by the Company in reports it files or submits under the Exchange Act is (i) recorded, processed, summarized and reported within the
time periods specified in SEC rules and forms and (ii) accumulated and communicated to the Companys management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding
required disclosure.

We carried out an evaluation, under the supervision and with the participation of our management,
including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended). Based upon that
evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report.

Changes in Internal Controls Over Financial Reporting

No changes in our internal control over financial reporting occurred during the quarter ended June 30, 2010 that have materially
affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings

In July 2007, the Audit Committee of our Board of Directors concluded a comprehensive review of our historical practices related to the
granting of stock options. In connection with the review, we had discussions with the U.S. Attorneys office for the Southern District of Florida concerning the matters covered by the review and, in response to a subpoena received in December
2007, provided the office with various documents and information related to our stock option granting practices. Although we intend to continue full cooperation with the U.S. Attorneys office, we cannot predict the outcome of this matter.

In September 2006, we completed a final settlement agreement with the Department of Justice and a relator who initiated a
qui tam complaint against us relating to our billing practices for services reimbursed by Medicaid, the Federal Employees Health Benefit program, and the United States Department of Defenses TRICARE program for military dependents
and retirees (Federal Settlement Agreement). In February 2007, we completed separate state settlement agreements with each state Medicaid program involved in the settlement (the State Settlement Agreements). Under the terms
of the Federal Settlement Agreement and State Settlement Agreements, we paid $25.1 million to the federal government and participating state Medicaid programs in connection with our billing for neonatal services provided from January 1996 through
December 1999.

As part of the Federal Settlement Agreement, we are under a five-year Corporate Integrity Agreement with the
OIG. The Corporate Integrity Agreement acknowledges the existence of our comprehensive Compliance Plan, which provides for policies and procedures aimed at promoting our adherence with FHC Program requirements and requires us to maintain the
Compliance Plan in full operation for the term of the Corporate Integrity Agreement. In addition, the Corporate Integrity Agreement requires, among other things, that we must comply with the following integrity obligations during the term of the
Corporate Integrity Agreement:



| |  |  | maintaining a Chief Compliance Officer and Compliance Committee to administer compliance with FHC Program requirements, the Compliance Plan and the
Corporate Integrity Agreement;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | maintaining the Code of Conduct for our officers, directors, employees, contractors, subcontractors, agents, or other persons who provide patient care
items or services (the Covered Persons);
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | maintaining the written policies and procedures regarding the operation of the Compliance Plan and our compliance with FHC Program requirements;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | providing general compliance training to the Covered Persons as well as specific training to the Covered Persons who perform coding functions relating
to claims for reimbursement from any FHC Program;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | engaging an independent review organization to perform annual reviews of samples of claims from multiple hospital units to assist us in assessing and
evaluating its coding, billing, and claims-submission practices;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | maintaining a Disclosure Program that includes a mechanism to enable individuals to confidentially disclose issues or questions believed by the
individual to be a potential violation of criminal, civil, or administrative laws;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | not hiring or, if employed, removing from our business operations which are related to or compensated, in whole or part, by FHC Programs, persons
(i) convicted of a criminal offense related to the provision of healthcare items or services or (ii) ineligible to participate in FHC Programs or Federal procurement or non-procurement programs;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | notifying the OIG of (i) new investigations or legal proceedings by a governmental entity or its agents involving an allegation that we have
committed a crime or have engaged in fraudulent activities, (ii) matters that a reasonable person would consider a probable violation of criminal, civil or administrative laws applicable to any FHC Program for which penalties or exclusion may
be imposed, and (iii) the purchase, sale, closure, establishment, or relocation of any facility furnishing items or services that are reimbursed under FHC Programs;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | reporting and returning overpayments received from FHC Programs;
| | - |  | ----------------------------------------------------------------



| |  |  | submitting reports to the OIG regarding our compliance with the Corporate Integrity Agreement; and
| | - |  | --------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | maintaining for inspection, for a period of six years from the effective date, all documents and records relating to reimbursement from the FHC
Programs and compliance with the Corporate Integrity Agreement.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Failure to comply with our duties under the
Corporate Integrity Agreement could result in substantial monetary penalties and in the case of a material breach, could even result in us being excluded from participating in FHC Programs. We believe that we were in compliance with the Corporate
Integrity Agreement as of June 30, 2010.

We expect that additional audits, inquiries and investigations from government
authorities and agencies will continue to occur in the ordinary course of business. Such audits, inquiries and investigations and their ultimate resolutions, individually or in the aggregate, could have a material adverse effect on our business,
financial condition, results of operations, cash flows, or the trading price of our common stock.

In the ordinary course of
business, we become involved in pending and threatened legal actions and proceedings, most of which involve claims of medical malpractice related to medical services provided by our affiliated physicians. Our contracts with hospitals generally
require us to indemnify them and their affiliates for losses resulting from the negligence of our affiliated physicians. We may also become subject to other lawsuits which could involve large claims and significant defense costs. We believe, based
upon a review of pending actions and proceedings, that the outcome of such legal actions and proceedings will not have a material adverse effect on our business, financial condition or results of operations. The outcome of such actions and
proceedings, however, cannot be predicted with certainty and an unfavorable resolution of one or more of them could have a material adverse effect on our business, financial condition, results of operations and the trading price of our common stock.

Although we currently maintain liability insurance coverage intended to cover professional liability and certain other
claims, we cannot assure that our insurance coverage will be adequate to cover liabilities arising out of claims asserted against us in the future where the outcomes of such claims are unfavorable. With respect to professional liability risk, we
generally self-insure a portion of this risk through our wholly owned captive insurance subsidiary. Liabilities in excess of our insurance coverage, including coverage for professional liability and certain other claims, could have a material
adverse effect on our business, financial condition and results of operations.

Item 1A. Risk Factors

There have been no material changes to the risk factors previously disclosed in the Companys most recent Annual Report
on Form 10-K.
