NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

September 30, 2010

(Unaudited)

(Dollars in thousands, except per share amounts)

1. Basis of Presentation, Principles of Consolidation, and Use of Estimates

Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared by Alliance
HealthCare Services, Inc. (the Company) in accordance with accounting principles generally accepted in the United States of America and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the
Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments
(including normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the quarter and nine months ended September 30, 2010 are not necessarily indicative of the results that may be expected
for the year ending December 31, 2010. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes to the consolidated financial statements
for the year ended December 31, 2009.

On January 1, 2009, the Company adopted Financial Accounting Standards Board
(FASB) Accounting Standards Codification (ASC) 810, Consolidation. ASC 810 requires, among other things, that cash flows related to noncontrolling interest in subsidiaries be presented in the financing section of
the Statement of Cash Flows rather than the operating section for the nine months ended September 30, 2010. In conformity with the current year presentation, the Company reclassified Noncontrolling interest in subsidiaries from the operating
section to the financing section of the Statement of Cash Flows for the nine months ended September 30, 2009.

Principles of Consolidation The accompanying unaudited condensed consolidated financial statements of the Company include the
assets, liabilities, revenues and expenses of all majority owned subsidiaries over which the Company exercises control. Intercompany transactions have been eliminated. The Company records noncontrolling interest related to its consolidated
subsidiaries which are not wholly owned. Investments in non-consolidated investees are accounted for under the equity method.

Use of Estimates The preparation of condensed consolidated financial statements in conformity with accounting principles generally
accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ from those
estimates.

2. Transactions

During December 2009, the Company entered into and completed various debt related transactions in order to expand its borrowing capacity and extend the maturity of its debt (the Refinance
Transaction). In order to accomplish this, the Company retired substantially all of its $300,000
71/4% senior subordinated notes due 2012 (the
71/4% Notes) through a cash tender
offer (the Tender Offer) and repaid the balance of $351,600 on its existing Tranche C1 term loan facility (the Old Term Loan). In conjunction with the Refinance Transaction, the Company entered into a new senior secured
credit agreement (the New Credit Facility), comprised of a $460,000 term loan (the New Term Loan) maturing June 2016 and a $120,000 revolving facility (the New Revolving Credit Facility) maturing December 2014.
Borrowings under the New Term Loan were issued at 98.0% of par, with the discount to par being amortized to interest expense and other, net through the maturity date of the loan. Borrowings under the New Credit Facility bear interest through
maturity at a variable rate based upon, at the Companys option, either London InterBank Offered Rate (LIBOR) or the base rate (which is the highest of the administrative agents prime rate, one-half of 1.00% in excess of the
overnight federal funds rate, and 1.00% in excess of the one-month LIBOR rate), plus in each case, an applicable margin. With respect to the New Term Loan, the applicable margin for LIBOR loans is 3.50% per annum, and with respect to the New
Revolving Credit Facility, the applicable margin for LIBOR loans ranges, based on the applicable leverage ratio, from 3.25% to 3.75% per annum, in each case, with a LIBOR floor of 2.00%. With respect to the New Term Loan, the applicable margin
for base rate loans is 2.50% per annum, and with respect to the New Revolving Credit Facility, the applicable margin for base rate loans ranges, based on the applicable leverage ratio, from 2.25% to 2.75% per annum. The Company also issued
$190,000 of 8.0% senior notes due 2016 (the 8% Notes) in a transaction that was exempt from the registration requirements of the Securities Act of 1933, as amended. On April 29, 2010, the Company filed a registration statement, per
the Registration Rights Agreement, which was declared effective on July 16, 2010, with the Securities and Exchange Commission with respect to an offer to exchange the private 8% Notes for new 8% Notes with substantially similar terms registered
under the Securities Act of 1933, as amended. The 8% Notes were issued at 98.69% of par, with the discount to par being amortized to interest expense and other, net

through the maturity date of the notes. The Company used the proceeds from these transactions and existing cash to complete the Tender Offer and purchase $294,418 of the 71/4% Notes at a purchase price equal to 100.125% of the principal amount, together with the accrued interest to the redemption date. The Company also used the proceeds from these
transactions to pay off the Old Term Loan and redeem the remaining $5,582 of 71/4% Notes in January 2010 at a redemption price equal to 100.0% of the
principal amount, together with accrued interest to the redemption date. The Company incurred a loss on extinguishment of debt of $14,600 in December 2009 related to the Refinance Transaction, which represents the tender premium and consent payment
to redeem the 71/4% Notes, write-off of unamortized debt issuance costs related to the retired debt, and other fees and expenses.

In the second quarter of 2010, the Company purchased a majority of the outstanding membership interests
of Radiology 24/7, LLC (RAD 24/7), a teleradiology services company, which provides primarily final, subspecialty professional radiology interpretation services and outsourced staffing services for magnetic resonance imaging
(MRI), positron emission tomography/computed tomography (PET/CT), computed tomography (CT), mammography, X-Ray and other imaging modalities and also preliminary radiology interpretation services in 16 states. The
purchase price consisted of $8,860 in cash, $3,775 in contingent payments, and $659 in assumed liabilities. The Company financed this acquisition using internally generated funds. As a result of this acquisition, the Company recorded goodwill of
$9,883 and acquired intangible assets of $8,000, of which $6,450 was assigned to customer relationships, which are being amortized over ten years, and $1,450 was assigned to trademarks, which are being amortized over seven years. The intangible
assets were recorded at fair value at the acquisition date. All recorded goodwill and intangible assets are capitalized for tax purposes and are being amortized over 15 years. The acquisition included $3,775 for contingent payments due upon the
achievement of certain revenue targets, which is expected to be resolved over the two years following the acquisition date. All contingent payments were recorded at fair value at the acquisition date. The fair value of noncontrolling interest
related to this transaction was $5,036 as of the acquisition date. During the quarter and nine months ended September 30, 2010, the Company recognized $244 in earnings related to decreasing the estimated value of contingent consideration. The
values assigned to the assets and liabilities acquired are preliminary and may be subject to adjustment. The nine months ended September 30, 2010 included six months of operations from this acquisition.

Also in the second quarter of 2010, the Company purchased all of the outstanding membership interests of Diagnostic Health Center of
Anchorage, LLC (DHC), a fixed-site imaging center located in Anchorage, Alaska. The center operates in a Certificate-of-Need state, and is a multi-modality imaging center which provides MRI, CT, digital mammography, X-Ray and other
imaging services. The purchase price consisted of $13,737 in cash and $554 in assumed liabilities. The Company financed this acquisition using internally generated funds. As a result of this acquisition, the Company recorded goodwill of $3,764 and
acquired intangible assets of $8,100, of which $6,400 was assigned to the physician referral network, which is being amortized over ten years, and $1,750 was assigned to certificates of need held by DHC, which have indefinite useful lives and are
not subject to amortization. The intangible assets were recorded at fair value at the acquisition date. All recorded goodwill and intangible assets are capitalized for tax purposes and are being amortized over 15 years. The values assigned to
the assets and liabilities acquired are preliminary and may be subject to adjustment. The nine months ended September 30, 2010 included four months of operations from this acquisition.

In the third quarter of 2010, the Company purchased certain assets from Arkansas Cancer Center, P.A., located in Pine Bluff, Arkansas
(Pine Bluff). This is the Companys third Arkansas-based radiation therapy facility and is a strategic addition to the Companys Bethesda cancer network, now totaling ten centers located throughout Alabama, Mississippi,
Arkansas and Missouri. The purchase price consisted of $9,489 in cash, $427 in contingent payments and $6 in assumed liabilities. The Company financed this acquisition using internally generated funds. As a result of this acquisition, the Company
recorded goodwill of $4,098 and acquired intangible assets of $5,250, of which $3,800 was assigned to the physician referral network, which is being amortized over ten years, $1,000 was assigned to trademarks, which are being amortized over ten
years, $350 was assigned to a professional services agreement, which is being amortized over nine years and $100 was assigned to the non-compete agreement, which is being amortized over nine years. The intangible assets were recorded at fair value
at the acquisition date. The acquisition included a one-third interest in a joint venture which was recorded at a fair value of $250 at the acquisition date. All recorded goodwill and intangible assets are capitalized for tax purposes and are being
amortized over 15 years. The acquisition included $427 for contingent payments due upon the resolution of certain claims, which are expected to be resolved over the six months following the acquisition date. All contingent payments were
recorded at fair value at the acquisition date. As of September 30, 2010, the amounts recognized for the contingent consideration arrangements and the assumptions used to develop the estimates have not changed. The values assigned to the assets
and liabilities acquired are preliminary and may be subject to adjustment. The nine months ended September 30, 2010 included three months of operations from this acquisition.

The Company has not included pro forma information as these acquisitions did not have a material impact on its consolidated financial
position or results of operations, individually or in the aggregate.

3. Share-Based Payment

The Company adopted ASC 718, CompensationStock Compensation in the fiscal year beginning January 1,
2006, using the modified prospective application transition method. Under ASC 718, the Company records in its consolidated statements of operations (i) compensation cost for options granted, modified, repurchased or cancelled on or after
January 1, 2006 under the provisions of ASC 718 and (ii) compensation cost for the unvested portion of options granted prior to January 1, 2006 over their remaining vesting periods using the amounts previously measured under ASC 718
for pro forma disclosure purposes.

The Company has elected to follow the alternative transition method as described in ASC
718 for computing its beginning additional paid-in capital pool. In addition, the Company treats the tax deductions from stock options as being realized when they reduce taxes payable in accordance with the principles and timing under the relevant
tax law.

Stock Option Plans and Awards

In November 1999, the Company adopted an employee stock option plan (the 1999 Equity Plan) pursuant to which options and awards with respect to a total of 6,325,000 shares of the
Companys common stock became available for grant. On May 30, 2007, the Company adopted an amendment to the 1999 Equity Plan which increased the number of shares available to be awarded to 8,025,000 shares. On May 27, 2009, the
Company adopted an amendment to the 1999 Equity Plan which increased the number of shares available to be awarded to 11,025,000 shares. As of September 30, 2010, a total of 2,060,212 shares were available for grant under the 1999 Equity Plan.
Options are granted with exercise prices equal to the fair value of the Companys common stock at the date of grant, except as noted below. All options have 10-year terms. Options granted after January 1, 2008 are time options which vest
25% each year, over four years. For options granted prior to January 1, 2008, initial stock option grants were comprised 50% of time options and 50% of performance options. The time options have a five-year vesting
schedule, vesting 20% per year. The performance options cliff vest after eight years; however, in the event certain operating performance targets are met, up to 20% of the performance options may vest each year, accelerating the vesting period
up to five years. During the nine months ended September 30, 2010 and the year ended December 31, 2009, there were no options in which vesting was accelerated. Prior to January 1, 2008, subsequent stock options granted under the 1999
Equity Plan to employees were always time options which vest 5% in the first year, 20% in the second year and 25% in years three through five.

In November 2000, the Company granted stock options to certain employees at exercise prices below the fair value of the Companys common stock, of which 35,000 options were outstanding at
September 30, 2010. The exercise prices of these options and the fair value of the Companys common stock on the grant date were $5.60 and $9.52 per share, respectively.

The Company uses the Black-Scholes option pricing model to value the compensation expense associated with share-based payment awards. The
fair value of each option award is estimated on the date of grant using the Black-Scholes option pricing model using the assumptions noted in the table below. In addition, forfeitures are estimated when recognizing compensation expense and the
estimate of forfeitures will be adjusted over the requisite service period to the extent that actual forfeitures differ, or are expected to differ, from such estimates. Changes in estimated forfeitures will be recognized through a cumulative
catch-up adjustment in the period of change and will also impact the amount of compensation expense to be recognized in future periods. The Company records share-based payments for stock options granted with exercise prices below the fair value of
the Companys common stock at the date of grant and for certain stock options subject to amended performance targets under the 1999 Equity Plan, as discussed below.

The following weighted-average assumptions were used in the estimated grant date fair value calculations for stock option awards:

The expected stock
price volatility rate for the nine months ended September 30, 2010 was based on the historical volatility of the Companys common stock. The expected stock price volatility rate for the quarter and nine months ended September 30, 2009
was based on a blend of the historical volatility of the Companys common stock and peer implied volatility. The risk free interest rates are based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with
the expected life of the option or award. The average expected life represents the weighted-average period of time that options or awards granted are expected to be outstanding, as calculated using the simplified method described in ASC 718, as the
Company does not have sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term.

The following table summarizes the Companys stock option activity:

At September 30, 2010, the total unrecognized fair value share-based payment related to
unvested stock options granted to both employees and non-employees was $4,528, which is expected to be recognized over a remaining weighted-average period of 2.09 years. The valuation model applied in this calculation utilizes highly subjective
assumptions that could potentially change over time, including the expected forfeiture rate and performance targets. Therefore the amount of unrecognized share-based payment noted above does not necessarily represent the value that will ultimately
be realized by the Company in the statements of operations. The total fair value of shares vested during the quarters ended September 30, 2009 and 2010 was $38 and $66, respectively. The total fair value of shares vested during the nine months
ended September 30, 2009 and 2010 was $1,883, and $2,486, respectively.

Restricted
Stock Awards

The 1999 Equity Plan, as amended and restated, permits the award of restricted stock, restricted stock units,
stock bonus awards and performance-based awards. During 2008, the Company granted 290,000 restricted stock awards (awards) to certain employees of the Company. During 2009, the Company granted 310,000 awards to certain employees and
66,016 awards to non-employees of the Company. During 2010, the Company granted 780,000 awards to certain employees of the Company. These awards cliff vest after one to five years, provided that the employee remains continuously employed and the
non-employee continues service through the issuance date. Also during 2010, the Company granted 33,000 awards, which vested immediately, to a certain employee of the Company. On December 31, 2009, the Company granted restricted stock awards to
three non-employee directors of the Company who are unaffiliated with Oaktree Capital Management, LLC (Oaktree) and MTS Health Investors, LLC (MTS) (unaffiliated directors) equal to 13,672 shares of
common stock each. These awards to unaffiliated directors cliff vest after one year based on the unaffiliated directors continued service with the Company through that date. For the quarters ended September 30, 2009 and 2010, the Company
recorded share-based payment related to restricted stock awards of $704 and $781, respectively. For the nine months ended September 30, 2009 and 2010, the Company recorded share-based payment related to restricted stock awards of $2,010 and
$2,211, respectively. The weighted-average grant date fair value of restricted stock awards granted during the quarters ended September 30, 2009 and 2010 was $5.25 and $2.12 per share, respectively. The weighted-average grant date fair value of
restricted stock awards granted during the nine months ended September 30, 2009 and 2010 was $6.26 and $5.34 per share, respectively.

The following table summarizes the Companys unvested restricted stock activity:

At September 30, 2010, the total unrecognized fair value share-based payment related to
restricted stock awards granted to employees was $4,864, which is expected to be recognized over a remaining weighted-average period of 1.99 years. At September 30, 2010, the total unrecognized fair value share-based payment related to the
restricted stock awards granted to unaffiliated directors was $60, which is expected to be recognized over a remaining weighted-average period of 0.25 years. The unaffiliated directors will each receive a restricted stock award on
December 31, 2010 and each December 31 thereafter (the Grant Date) of the number of shares of common stock having a value equal to $80, rounded down to the nearest whole share, and calculated using the average share price of
the Companys stock over the fifteen-day period preceding the Grant Date. Such restricted stock awards will fully vest one year after the Grant Date based on the continued service of the non-employee director through the vesting date. The
valuation model applied in this calculation utilizes highly subjective assumptions that could potentially change over time, including the expected forfeiture rate. Therefore the amount of unrecognized share-based payment noted above does not
necessarily represent the amount that will ultimately be realized by the Company in the statements of operations.

Stock
Bonus Award

During 2006 and 2007, the Company granted stock bonus awards to certain employees of the Company. On the
issuance date, the Company issued a number of shares of the Companys common stock (shares), equal to the award divided by the fair market value of the shares at that time. During the nine months ended September 30, 2009, the
Company issued 125,470 shares related to the stock bonus awards granted in 2006. During the nine months ended September 30, 2010, the Company issued 87,565 shares related to the stock bonus awards granted in 2007. For the quarter and nine
months ended September 30, 2009, the Company recorded share-based payment related to these grants of $42 and $125, respectively. There are no unvested stock bonus awards as of December 31, 2009.

4. Recent Accounting Pronouncements

Variable Interest Entities Accounting Standards Update (ASU) No. 2009-17, Improvements to Financial Reporting by Enterprises Involved With Variable Interest Entities
(ASU 2009-17), enhances the current guidance on

disclosure requirements for companies with financial interests in a variable interest entity. ASU 2009-17 replaces the quantitative-based risks and rewards calculation for determining which
enterprise, if any, has a controlling financial interest in a variable interest entity with an approach focused on identifying which enterprise has the power to direct the activities of a variable interest entity that most significantly impact the
entitys economic performance and (a) the obligation to absorb losses of the entity or (b) the right to receive benefits from the entity. ASU 2009-17 requires an additional reconsideration event when determining whether an entity is a
variable interest entity when any changes in facts and circumstances occur such that the holders of the equity investment at risk, as a group, lose the power of voting rights or similar rights of those investments to direct the activities of the
entity that most significantly impact the entitys economic performance. It also requires ongoing assessments of whether an enterprise is the primary beneficiary of a variable interest entity. ASU 2009-17 requires additional disclosures about
an enterprises involvement in variable interest entities. ASU 2009-17 is effective for fiscal years beginning after November 15, 2009, with early application prohibited. The Company adopted the provisions of ASU 2009-17 on January 1,
2010. The adoption of ASU 2009-17 did not have a material impact on the Companys results of operations, cash flows or financial position.

Fair Value of Financial Instruments ASU No. 2010-06, Improving Disclosures about Fair Value Measurements (ASU 2010-06), amends ASC 820, Fair Value Measurements
and Disclosures, to add new requirements for disclosures about transfers into and out of Levels 1 and 2 and separate disclosures about purchases, sales, issuances, and settlements relating to Level 3 measurements. ASU 2010-06 also
clarifies existing fair value disclosures about the level of disaggregation and about inputs and valuation techniques used to measure fair value. Further, ASU 2010-06 amends guidance on employers disclosures about postretirement benefit
plan assets under ASC 715 to require that disclosures be provided by classes of assets instead of by major categories of assets. ASU 2010-06 is effective for the first reporting period (including interim periods) beginning after
December 15, 2009, except for the requirement to provide the Level 3 activity of purchases, sales, issuances, and settlements on a gross basis, which will be effective for fiscal years beginning after December 15, 2010, and for
interim periods within those fiscal years. The Company adopted the provisions of ASU 2010-06 on January 1, 2010. The adoption of ASU 2010-06 did not have a material impact on the Companys results of operations, cash flows or financial
position.

5. Fair Value of Financial Instruments

The Company used the following methods and assumptions in estimating fair value disclosure for financial instruments:

Cash and cash equivalents The carrying amounts reported in the balance sheet approximate fair value due to the short-term maturity or variable rates of these instruments.

Debt The fair value of the Companys fixed-rate debt was based on open bid/ask quotations of those notes at December 31,
2009 and September 30, 2010. The carrying amount of variable-rate borrowings at September 30, 2010 approximates fair value estimated based on current market rates and credit spreads for similar debt instruments.

Derivative instruments Fair value was determined based on the income approach and standard valuation techniques to convert future
amounts to a single present amount and approximates the net gains and losses that would have been realized if the contracts had been settled at each period-end.

The estimated fair values of the Companys financial instruments are as follows:

The Company adopted
ASC 825, Financial Instruments on January 1, 2008. ASC 825 applies to all assets and liabilities that are being measured and reported on a fair value basis. ASC 825 requires disclosure that establishes a framework for measuring fair
value in generally accepted accounting principles, and expands disclosure about fair value measurements. This statement enables the reader of the financial statements to assess the inputs used to develop those measurements by establishing a
hierarchy for ranking the quality and reliability of the information used to determine fair

The Companys derivative instruments are primarily pay-fixed, receive-variable interest rate swaps and
caps based on LIBOR swap rate. The Company has elected to use the income approach to value these derivatives, using observable Level 2 market expectations at measurement date and standard valuation techniques to convert future amounts to a
single present amount assuming that participants are motivated, but not compelled to transact. Level 2 inputs for interest rate swap and cap valuations are limited to quoted prices for similar assets or liabilities in active markets
(specifically futures contracts on LIBOR for the first two years) and inputs other than quoted prices that are observable for the asset or liability (specifically LIBOR cash and swap rates at commonly quoted intervals and implied volatilities for
options). The Company has identified both a public and a private data source for use in valuing the Department of Energy (DOE) diesel fuel swap. There appears to be a material difference in the pricing for diesel fuel contracts traded on
NYMEX and the pricing that brokers make available to retail clients hedging changes in the DOE average national diesel fuel price as executed by the Company. As a

result the Company has elected to use broker data available from its counterparty and informally corroborated by a second broker to fair value the diesel fuel swap. The September 30, 2010
over-the-counter forward rates were compared to the fixed rates executed by the Company for each forward date. The loss on each forward date was then present valued at LIBOR plus a credit spread of 3.5%. Mid-market pricing is used as a practical
expedient for fair value measurements. ASC 820 states that the fair value measurement of an asset or liability must reflect the nonperformance risk of the entity and the counterparty. Therefore, the impact of the counterpartys creditworthiness
and the Companys creditworthiness has also been factored into the fair value measurement of the derivative instruments. For additional information please see Note 9 of the Notes to the Condensed Consolidated Financial Statements.

In accordance with ASC 350, IntangiblesGoodwill and Other, the Company has selected to
perform an annual impairment test for goodwill and indefinite life intangible assets based on the financial information as of September 30, or more frequently when an event occurs or circumstances change that would more likely than not reduce
the fair value of a reporting unit below its carrying amount. The Company compares the fair value of its reporting units to its carrying amount to determine if there is potential impairment. The fair value of the reporting unit is determined by an
income approach and a market capitalization approach. Significant management judgment is required in the forecasts of future operating results that are used in the income approach. The estimates that the Company has used are consistent with the
plans and estimates that it uses to manage its business. The Company bases its fair value estimates on forecasted revenue and operating costs which include a number of factors including, but not limited to, securing new customers, retention of
existing customers, growth in imaging and radiation oncology revenues and the impact of continued cost savings initiatives. It is possible, however, that the plans may change and estimates used may prove to be inaccurate. If the actual results, or
the plans and estimates used in future impairment analyses, are lower than the original estimates used to assess the recoverability of these assets, the Company could incur an impairment charge. A significant decrease in the future market
capitalization of the Company may also indicate that an impairment charge may be incurred in connection with a future impairment test. In 2009 and the first nine months of 2010, the Company concluded that no impairment was present in its
goodwill or other intangible assets.

The Company uses the estimated useful life to amortize customer contracts, which is a
weighted-average of 12 years. Other intangible assets subject to amortization are estimated to have a weighted average useful life of six years. Amortization expense for intangible assets subject to amortization was $2,721 and $3,308 for the
quarters ended September 30, 2009 and

2010, respectively, and $8,259 and $9,201 for the nine months ended September 30, 2009 and 2010, respectively. The intangible assets not subject to amortization represent certificates of

9. Derivatives

The
Company accounts for derivative instruments and hedging activities in accordance with the provisions of ASC 815, Derivatives and Hedging. Management generally designates derivatives in a hedge relationship with the identified exposure on
the date the Company enters into a derivative contract, as disclosed below. The Company has only executed derivative instruments that are economic hedges of exposures that can qualify in hedge relationships under ASC 815. The Company formally
documents all relationships between hedging instruments and hedged items, as well as the risk-management objective and strategy for undertaking various hedge transactions. In this documentation, the Company specifically identifies the firm
commitment or forecasted transaction that has been designated as a hedged item and states how the hedging instrument is expected to hedge the risks related to the hedged item. The Company formally assesses effectiveness of its hedging relationships,
both at the hedge inception and on an ongoing basis, then measures and records

ineffectiveness. The Company would discontinue hedge accounting prospectively (i) if it is determined that the derivative is no longer effective in offsetting change in the cash flows of a
hedged item, (ii) when the derivative expires or is sold, terminated or exercised, (iii) because it is probable that the forecasted transaction will not occur, or (iv) if management determines that designation of the derivative as a
hedge instrument is no longer appropriate. The Companys derivatives are recorded on the balance sheet at their fair value. For additional information please see Note 5 of the Notes to the Condensed Consolidated Financial Statements. For
derivatives accounted for as cash flow hedges, any effective unrealized gains or losses on fair value are included in comprehensive income (loss), net of tax, and any ineffective gains or losses are recognized in income immediately. Amounts recorded
in comprehensive income (loss) are reclassified to earnings when the hedged item impacts earnings.

Cash Flow Hedges

Interest Rate Cash Flow Hedges

The Company has entered into multiple interest rate swap and cap agreements to hedge the future cash interest payments on portions of its variable rate bank debt. For the nine months ended
September 30, 2009 and 2010, the Company had interest rate swap and cap agreements to hedge approximately $242,250 and $242,719 of its variable rate bank debt, respectively, or 36.5% and 37.0% of total debt, respectively. Over the next twelve
months, the Company expects to reclassify $843 from accumulated other comprehensive loss to interest expense and other, net.

In the first quarter of 2008, the Company entered into two interest rate swap agreements in accordance with Company policy in order to
avoid unplanned volatility in the income statement due to changes in the LIBOR interest rate environment. The swap agreements, with a total notional amount of $185,438, were designated as cash flow hedges of future cash interest payments associated
with a portion of the Companys variable rate bank debt (the 2008 swaps). These agreements were three years in length and set to mature in January 2011. Under the terms of these agreements, the Company received three-month LIBOR and
paid a fixed rate of 3.15%. The net effect of the hedges was to record interest expense at a fixed rate of 5.65%, as the underlying debt incurred interest based on three-month LIBOR plus 2.50%. See below for additional information regarding the 2008
swaps. As discussed below, the Company elected to terminate and replace one of the 2008 swaps in the first quarter of 2009.

On September 15, 2008, Lehman Brothers Holdings, Inc. (LHI) filed for bankruptcy protection under Chapter 11
of the United States Bankruptcy Code. On October 6, 2008, Lehman Commercial Paper, Inc. (LCPI) filed for bankruptcy protection under Chapter 11 of the United States Bankruptcy Code. One of the Companys 2008 swaps
with a notional amount of $92,719 was with LCPI (the Lehman Swap). As of September 12, 2008, hedge accounting was terminated and all further changes in the fair market value of this swap were recorded in interest expense and other,
net. Comprehensive income (loss) related to effective unrealized gains or losses on the fair value of the swap through September 12, 2008 will remain in accumulated comprehensive income (loss) on the balance sheet and will be amortized into
interest expense and other, net through 2011 as the underlying interest payments are recognized in earnings. The swap was valued using the income approach with observable Level 2 market expectations at the measurement date and standard
valuation techniques to convert future amounts to a single discounted present amount.

During the first quarter of 2009, the
Company replaced the Lehman Swap with an interest rate swap agreement which had a notional amount of $92,719 (the 2009 Swap Replacement) that had been designated as a cash flow hedge of variable future cash flows associated with a
portion of the Companys long-term debt. Under the terms of this agreement, which matures in January 2011, the Company receives three-month LIBOR and pays a fixed rate of 3.15%. The net effect of the hedge is to record interest expense at a
fixed rate of 5.65%, as the debt incurs interest based on three-month LIBOR plus 2.50%.

Additionally, during the first
quarter of 2009, the Company entered into an additional interest rate swap agreement which has a notional amount of $56,813 that has been designated as a cash flow hedge of future interest payments associated with a portion of the Companys
variable rate bank debt (the New 2009 Swap). Under the terms of this agreement, which was to mature in November 2011, the Company received three-month LIBOR and paid a fixed rate of 2.07%. The net effect of the hedge was to record
interest expense at a fixed rate of 4.57%, as the underlying debt incurred interest based on three-month LIBOR plus 2.50%.

The Company elected to terminate one of the 2008 swaps and the New 2009 Swap in December 2009 in connection with entering into the
Refinance Transaction on December 1, 2009. As a result of the Refinance Transaction, the Company de-designated the 2008 swap, the 2009 Swap Replacement and the New 2009 Swap and hedge accounting was terminated and all further changes in the
fair market value of these swaps are being recorded in interest expense and other, net. Comprehensive income (loss) related to effective unrealized gains or losses on the fair value of these swaps through September 30, 2009 remain in
accumulated comprehensive income (loss) on the balance sheet and will be amortized into interest expense and other, net as the underlying interest payments are recognized in earnings. These swaps were valued

using the income approach with observable Level 2 market expectations at the measurement date and standard valuation techniques to convert future amounts to a single discounted present
amount.

In the first quarter of 2010, the Company entered into one interest rate swap agreement (the 2010 Swap)
and three interest rate cap agreements, in accordance with Company policy, in order to avoid unplanned volatility in the income statement due to changes in the LIBOR interest rate environment. The 2010 Swap, which matures in January 2011, has a
notional amount of $92,719 and synthetically unwinds the effects of the 2009 Swap Replacement. The interest rate cap agreements, which mature in February 2014, have a total notional amount of $150,000 and were designated as cash flow hedges of
future cash interest payments associated with a portion of the Companys variable rate bank debt. Under these arrangements, the Company has purchased a cap on LIBOR at 4.50%. The Company paid $1,537 to enter into the caps, which is being
amortized through interest expense and other, net over the life of the agreements.

Diesel Fuel Cash Flow Hedges

The Company is exposed to market fluctuations in diesel fuel prices related to its mobile fleet. During the first quarter
of 2009, the Company entered into a diesel fuel swap agreement which had a notional quantity of 1,008,000 gallons, or 84,000 gallons per month, to hedge future cash payments associated with the Company purchasing diesel fuel for its mobile fleet.
Under the terms of this agreement, which matured in February 2010, the Company received the DOE published monthly average price per gallon and paid a fixed rate of two dollars and sixty-three cents per gallon. The Company designated this swap as a
cash flow hedge of future cash flows associated with its diesel fuel payments. The swap was designated in a cash flow relationship in the month following execution. The loss from trade date to designation date was recorded in other (income) and
expense, net. Post-designation, the Company recorded effective changes in the fair value of the swap through comprehensive income (loss) and reclassified gains or losses to fuel expense (included in cost of revenues, excluding depreciation and
amortization) when the underlying fuel was purchased.

During the first quarter of 2010, the Company entered into a diesel
fuel swap agreement which has a notional quantity of 1,008,000 gallons, or 84,000 gallons per month, to hedge future cash payments associated with the Company purchasing diesel fuel for its mobile fleet. Under the terms of this agreement, which
matures in February 2011, the Company receives the DOE published monthly average price per gallon and pays a fixed rate of three dollars and twenty-five cents per gallon. The Company designated this swap as a cash flow hedge of future cash flows
associated with its diesel fuel payments. The Company records effective changes in the fair value of the swap through comprehensive income (loss) and reclassifies gains or losses to fuel expense (included in cost of revenues, excluding depreciation
and amortization) when the underlying fuel is purchased.

10. Income Taxes

For the quarter and nine months ended September 30, 2010, the Company recorded an income tax benefit of $799 and $1,485, or 45.0% and
32.7%, of the Companys pretax loss, respectively. For the quarter and nine months ended September 30, 2009, the Company recorded a provision for income taxes of $2,053 and $8,269, or 40.5% and 41.8%, of the Companys pretax income,
respectively. Income tax (benefit) expense for the quarters and nine months ended September 30, 2010 and 2009 were based on estimated annual effective tax rates applied to pretax income (loss), adjusted for discrete items. The Companys
effective tax rates differed from the federal statutory rate principally as a result of state income taxes and permanent non-deductible tax items, including share-based payments, unrecognized tax benefits and other permanent differences.

As of September 30, 2010, the Company has provided a liability for $1,414 for unrecognized tax benefits related to various federal
and state income tax matters. The tax effected amount would reduce the Companys effective income tax rate if recognized.

The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense. As of
September 30, 2010, the Company had approximately $159 in accrued interest and penalties which is included as a component of the $1,414 unrecognized tax benefit noted above.

The Company is subject to U.S. federal income tax as well as income tax of multiple state tax jurisdictions. The Company is currently
open to audit under the statute of limitations by the Internal Revenue Service for the years ended December 31, 2007 through 2009. The Companys state income tax returns are generally open to audit under statutes of limitation for the
years ended December 31, 2005 through 2009. The Company does not anticipate a significant change to the total amount of unrecognized tax benefits within the next 12 months.

11. Earnings Per Common Share

Effective January 1, 2009, the Company adopted an update to ASC 260, Earnings Per Share, relating to
participating securities. ASC 260 addresses whether instruments granted in share-based payment transactions are participating securities prior to vesting and therefore need to be included in the earnings allocation in calculating earnings per share
under the two-class method described in ASC 260. ASC 260 requires companies to treat unvested share-based payment awards that have non-forfeitable rights to dividend or dividend equivalents as a separate class of securities in calculating earnings
per share. The Company granted and expects to continue to grant restricted stock awards to its officers and non-employee directors that contain non-forfeitable rights to dividends. Such awards are considered participating securities under ASC 260.
As such, the Company is required to include these awards in the calculation of the Companys basic earnings per share and calculate basic earnings per share using the two-class method. Restricted stock awards have previously been included in
the Companys dilutive earnings per share calculation using the treasury stock method. The two-class method of computing earnings per share is an earnings allocation formula that determines earnings per share for each class of common stock and
participating security according to dividends declared (or accumulated) and participation rights in undistributed earnings. The Company has historically not paid and does not expect to pay dividends in the foreseeable future; however, the Company
must still allocate undistributed earnings between common shareholders and participating securities based on the contractual rights of each security, as if all the earnings for the period have been distributed.

Basic net income per share is computed utilizing the two-class method and is calculated based on weighted-average number of common shares
outstanding during the periods presented, excluding nonvested restricted stock units which do not contain nonforfeitable rights to dividend and dividend equivalents.

Diluted net income per share is computed using the weighted-average number of common and common equivalent shares outstanding during the periods utilizing the two-class method for stock options, nonvested
restricted stock and nonvested restricted stock units. Potentially dilutive securities are not considered in the calculation of net loss per share as their impact would be anti-dilutive.

The following table sets forth the computation of basic and diluted earnings per share (amounts in thousands, except per share amounts):

12. Commitments and Contingencies

The Company has applied the disclosure provisions of ASC 460, Guarantees to its agreements that contain guarantee or indemnification clauses. These disclosure provisions expand those required
by ASC 440, Commitments, and ASC 450, Contingencies, by requiring a guarantor to disclose certain types of guarantees, even if the likelihood of requiring the guarantors performance is remote. The following is a
description of arrangements in which the Company is the guarantor or indemnifies a party.

In the normal course of business,
the Company has made certain guarantees and indemnities, under which it may be required to make payments to a guaranteed or indemnified party, in relation to certain transactions. The Company indemnifies other parties, including customers, lessors,
and parties to other transactions with the Company, with respect to certain matters. The Company has agreed to hold the other party harmless against losses arising from certain events as defined within the particular contract, which may include, for
example, litigation or claims arising from a breach of representations or covenants. In addition, the Company has entered into indemnification agreements with its executive officers and directors and the Companys bylaws contain similar
indemnification obligations. Under these arrangements, the Company is obligated to indemnify, to the fullest extent permitted under applicable law, its current or former officers and directors for various amounts incurred with respect to actions,
suits or proceedings in which they were made, or threatened to be made, a party as a result of acting as an officer or director.

It is not possible to determine the maximum potential amount under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances
involved in each particular agreement. Historically, payments made related to these indemnifications have been immaterial. At September 30, 2010, the Company has determined that no liability is necessary related to these guarantees and
indemnities.

In connection with
the Companys acquisition of Medical Outsourcing Services, LLC (MOS) in the third quarter of 2008, the Company subsequently identified a Medicare billing practice related to a portion of MOSs retail billing operations that
raised compliance issues under Medicare reimbursement guidelines. The practice was in place prior to the acquisition and was discontinued when the Company became aware of it. In accordance with its corporate compliance program, the Company has
entered into discussions with representatives of the federal government to advise them of the issue and seek guidance on appropriate next steps. The discussions are ongoing and no resolution has yet been reached. Although the government may seek
repayment and penalties relating to the billing practice, the Company does not expect that such repayment and penalties, if imposed on the Company, would have a material impact on the Companys results of operations, cash flows or financial
position because the Company believes the amounts it would owe will be substantially or fully off-set by recoveries under the indemnification provisions of the MOS acquisition purchase agreement. Pursuant to the terms of the purchase agreement, in
June 2010 the Company commenced arbitration proceedings related to this matter.

The Company from time to time is involved in
routine litigation and regulatory matters incidental to the conduct of its business. The Company believes that resolution of such matters will not have a material adverse effect on its consolidated results of operations or financial position.

13. Related-Party Transactions

On April 16, 2007, Oaktree and MTS purchased 24,501,505 shares of the Companys common stock from a fund managed by an affiliate of Kohlberg Kravis Roberts & Co (KKR). Upon
completion of the transaction, Oaktree and MTS owned in the aggregate approximately 49.7% of the outstanding shares of common stock of the Company. At September 30, 2010, Oaktree and MTS owned in the aggregate approximately 49.6% of the
outstanding shares of common stock of the Company. The Company does not pay management fees to Oaktree and MTS for their financial advisory services to the Company.

Revenues from management agreements with unconsolidated equity investees were $3,315 and $3,151 during the quarters ended September 30, 2009 and 2010, respectively. Revenues from management
agreements with unconsolidated equity investees were $11,483 and $9,678 during the nine months ended September 30, 2009 and 2010, respectively. The Company provides services as part of its ongoing operations for and on behalf of the
unconsolidated equity investees, which are included in the management agreement revenue, who reimburse the Company for the actual amount of the expenses incurred. The Company records the expenses as costs of revenues and the reimbursement as revenue
in its condensed consolidated statements of operations. For the quarters ended September 30, 2009 and 2010, the amounts of the revenues and expenses were $2,507 and $2,358, respectively. For the nine months ended September 30, 2009 and
2010, the amounts of the revenues and expenses were $8,979 and $7,019, respectively.

14. Investments in Unconsolidated Investees

The Company has direct ownership in six unconsolidated investees at September 30, 2010. The Company owns between
33.3% and 50% of these investees and provides management services under agreements with four of these investees, expiring at various dates through 2025. All of these investees are accounted for under the equity method since the Company does not
exercise control over the operations of these investees.

(Dollars in thousands, except per share amounts)





16. Segment Information

Operating segments are defined as components of an enterprise about which separate financial information is available
that is evaluated regularly by the chief operating decision maker (CODM) in deciding how to allocate resources and in assessing performance. Based on the nature of the financial information that is received by the CODM, the Company
operates in four operating segments, three of which are geographic regions and one oncology segment. Based on the aggregation criteria in ASC 280, Segment Reporting, the Company has aggregated the results of its four operating segments
into two reportable segments, Imaging and Radiation Oncology, based on similar economic and other characteristics.

In the
third quarter of 2010, the Radiation Oncology segment met the quantitative thresholds for separate reporting. As such, management has presented segment information for the quarter and nine months ended September 30, 2010. Prior period segment
information has been included for comparative purposes. The Imaging segment is comprised of diagnostic imaging services including MRI, PET/CT and other imaging services. The Radiation Oncology segment is comprised of radiation oncology services. All
intercompany revenues, expenses, payables and receivables are eliminated in consolidation and are not reviewed when evaluating segment performance. Each segments performance is evaluated based on Revenue, Segment Income and Net Income. The
accounting policies of the segments are the same as those described in the summary of significant accounting policies in Note 1 of the Notes to the Condensed Consolidated Financial Statements. Additionally, the Company does not consider its

The increase in goodwill in the Imaging segment was primarily due to the acquisitions completed in the
second quarter of 2010. The increase in goodwill in the Radiation Oncology segment was primarily due to the acquisition completed in the third quarter of 2010. For more information please refer to Notes 2 and 6 of the Notes to the Condensed
Consolidated Financial Statements.

Capital expenditures in the Imaging segment and the Radiation Oncology segment were
$15,198 and $405, respectively, for the quarter ended September 30, 2010, and $40,760 and $3,075, respectively, for the nine months ended September 30, 2010. Capital expenditures in the Imaging segment and the Radiation Oncology segment
were $16,438 and $1,087, respectively, for the quarter ended September 30, 2009, and $48,600 and $2,789, respectively, for the nine months ended September 30, 2009.

|ITEM 2. | MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
|------- | -------------------------------------------------------------------------------------

Overview

We are a leading national provider of advanced outpatient diagnostic imaging and radiation therapy services, based upon annual revenue and number of systems deployed. Our principal sources of revenue are
derived from magnetic resonance imaging (MRI) and positron emission tomography/computed tomography (PET/CT). We provide imaging and therapeutic services primarily to hospitals and other healthcare providers on a
shared-service and full-time service basis. We also provide services through a growing number of fixed-site imaging centers, primarily to hospitals or health systems. Our services normally include the use of our imaging systems, technologists to
operate the systems, equipment maintenance and upgrades and management of day-to-day shared-service and fixed-site diagnostic imaging operations. We also provide non scan-based services, which include only the use of our imaging systems under a
short-term contract. We have also leveraged our leadership in MRI and PET/CT to expand into radiation oncology. Our radiation oncology business is operated through our wholly-owned subsidiary, Alliance Oncology, LLC (AO), and
includes a wide range of services for cancer patients covering initial consultation, preparation for treatment, simulation of treatment, actual radiation oncology delivery, therapy management and follow-up care. Our services include the use of our
linear accelerators, therapists to operate such systems, administrative staff, equipment maintenance and upgrades, and management of day-to-day operations. We also provide stereotactic radiation oncology services through our wholly-owned subsidiary,
Alliance Radiosurgery, LLC.

MRI, PET/CT and radiation oncology services generated 45%, 39% and 9% of our revenue,
respectively, for the nine months ended September 30, 2010 and 48%, 40% and 7% of our revenue, respectively, for the nine months ended September 30, 2009. Our remaining revenue was comprised of other modality diagnostic imaging services
revenue, primarily computed tomography (CT) and management contract revenue. We had 521 diagnostic imaging and radiation oncology systems, including 301 MRI systems and 125 positron emission tomography (PET) or PET/CT
systems, and served over 1,000 hospitals and other healthcare partners in 46 states at September 30, 2010. We operated 126 fixed-site imaging centers (three in unconsolidated joint ventures), which constitute systems installed in hospitals
or other medical buildings on or near hospital campuses, including modular buildings, systems installed inside medical groups offices, and free-standing fixed-site imaging centers, which include systems installed in a medical office building,
ambulatory surgical center, or other retail space at September 30, 2010. Of the 126 fixed-site imaging centers, 98 were MRI fixed-site imaging centers, 20 were PET or PET/CT fixed-site imaging centers, five were other modality fixed-site
imaging centers and three were in unconsolidated joint ventures. We also operated 26 radiation oncology centers and stereotactic radiosurgery facilities (including two radiation oncology centers in unconsolidated joint ventures) at
September 30, 2010.

Approximately 81% and 80% of our revenues for the nine months ended September 30, 2010 and
2009, respectively, were generated by providing services to hospitals and other healthcare providers, which we refer to as wholesale revenues. Our wholesale revenues are typically generated from contracts that require our clients to pay us based on
the number of scans we perform on patients on our clients behalf, although some pay us a flat fee for a period of time regardless of the number of scans we perform. Wholesale payments are due to us independent of our clients receipt of
retail reimbursement from third-party payors, although receipt of reimbursement from third-party payors may affect demand for our services. We typically deliver our services for a set number of days per week through exclusive, long-term contracts
with hospitals and other healthcare providers. The initial terms of these contracts average approximately three years in length for mobile services and approximately five to 10 years in length for fixed-site arrangements. These contracts often
contain automatic renewal provisions and certain contracts have cancellation clauses if the hospital or other healthcare provider purchases their own system. We price our contracts based on the type of system used, the scan volume, and the number of
ancillary services provided. Pricing is also affected by competitive pressures.

Approximately 19% and 20% of our revenues for
the nine months ended September 30, 2010 and 2009, respectively, were generated by providing services directly to patients from our sites located at or near hospitals or other healthcare provider facilities, which we refer to as retail revenue.
Our revenue from these sites is generated from direct billings to patients or their third-party payors, including Medicare, which are recorded net of contractual discounts and other arrangements for providing services at discounted prices. We
typically charge a higher price per scan under retail billing than we do under wholesale billing.

Fixed-site imaging centers
and radiation oncology centers can be structured as either wholesale or retail arrangements. Our contracts for radiation oncology services average approximately 10 to 20 years in length. Revenues from these centers are included in either our
wholesale or retail revenues.

With respect to our
retail business, for services for which we bill Medicare directly, we are paid under the Medicare Physician Fee Schedule, which is updated on an annual basis. Under the Medicare statutory formula, payments under the Physician Fee Schedule would have
decreased for the past several years if Congress failed to intervene. For 2010, the Centers for Medicare and Medicaid Services (CMS) projected a rate reduction of 21.2% under the statutory formula unless Congress intervened again to
avoid the payment reduction. A number of legislative initiatives have prevented this reduction thus far, but on an incremental basis. The latest was the Preservation of Access to Care for Medicare Beneficiaries and Pension Relief Act of 2010, signed
into law on June 25, 2010, which not only prevented the rate reduction, but also increased payment rates by 2.2%, effective June 1, 2010 through November 30, 2010. These payment rates are currently scheduled to be reduced under the
statutory formula on December 1, 2010 and then again on January 1, 2011. CMS is currently projecting that the total reduction in payment rates will be 24.9%. If Congress fails to intervene to prevent the negative update factor in the future, the
resulting decrease in payment will adversely impact our revenues and results of operations.

For retail services furnished on
or after July 1, 2010, CMS began implementing a 50% reduction in reimbursement for multiple images on contiguous body parts, as mandated by the recently enacted Patient Protection and Affordable Care Act, as amended by the Health Care and
Education Affordability Reconciliation Act (collectively, the PPACA). This is a 25% increase from prior years. In its final Medicare Physician Fee Schedule rule for calendar year 2011, effective January 1, 2011, CMS will apply the same
reduction to certain CT and CT angiography (CTA), MRI and MR angiography (MRA), and ultrasound services furnished to the same patient in the same session, regardless of the imaging modality, and not limited to contiguous body
areas. CMS projects that the final rule will reduce payment for 20% more services than the current multiple procedure payment reduction policy. CMS expects that the final rule will primarily reduce payments for radiology services and to freestanding
diagnostic imaging centers, such as our retail business. At this time, we do not believe that the multiple procedure payment reductions will have a material impact on our future retail revenues.

Regulatory updates to the Physician Fee Schedule for calendar year 2010 include reduced payment rates for certain diagnostic services
using equipment costing more than $1 million through revisions to usage assumptions from the previous 50% usage rate to a 90% usage rate. This utilization change, to be phased in over a four-year period, applies to MRI and CT scans, but not for
radiation therapy and other therapeutic equipment. The PPACA superseded CMSs assumed usage rate for such equipment and, beginning on January 1, 2011, the PPACA requires CMS to use a 75% utilization rate. For 2011, CMS also finalized its
proposed rule to expand the list of services to which the higher equipment utilization rate assumption applies to include certain diagnostic CTA and MRA procedures using similar CT and MRI scanners that cost more than $1 million. At this time, we
estimate that the new usage assumptions for MRI and CT scans under the PPACA, which is to take effect on January 1, 2011, will not have a material impact on our future retail revenues.

Other regulatory changes to the 2010 Medicare Physician Fee Schedule involve revaluing certain components of the fee schedule payment
rate, which impact radiology and other diagnostic tests, including the services we provide. Some of these changes are being transitioned over a four year period, with full implementation in 2013. For the 2010 transition payment, CMS estimated that
the aggregate impact of its changes (which include the changes in the equipment utilization rate discussed above) results in a 1% reduction in radiation oncology, 5% reduction in radiology, 18% reduction in nuclear medicine and 12% reduction for all
suppliers providing the technical component of diagnostic tests generally. To date these changes have not had a material impact on our retail revenues. Effective January 1, 2011, CMS made further adjustments to the fee schedule so that specialties
that have a higher proportion of the payment rate attributable to operating expenses such as equipment and supplies, which include radiation oncology, will experience an increase in aggregate payments. In addition, as a result of adjustments to
codes identified to be misvalued, radiation oncology specialties and suppliers providing the technical component of diagnostic tests are among the entities that will experience decreases in aggregate payment. Some of these changes will be
transitioned, and CMS estimates that the impact for 2011 (which include the changes in the equipment utilization rate discussed above as well as the expanded multiple procedure payment reductions for certain imaging services) will be a 1% reduction
in radiation oncology, 10% reduction in radiology, 4% reduction in nuclear medicine and 15% reduction for all suppliers providing the technical component of diagnostic tests generally. These estimated impacts are calculated prior to the application
of the negative update factor discussed above. At this time, we do not believe that the regulatory changes will have a material impact on our future retail revenues.

In addition to annual updates to the Medicare Physician Fee Schedule, as indicated above, CMS also publishes regulatory changes to the hospital outpatient prospective payment system (HOPPS) on
an annual basis. These payments are the amounts received by our hospital clients for hospital outpatient services and summarized in the table below:

The PET and PET/CT Medicare HOPPS rate
reductions did not have a material negative effect on revenue and earnings in 2008, 2009 or the first nine months of 2010. At this time, however, we cannot predict the impact the rate reductions will have on our future revenues or business.

The 2011 HOPPS and Medicare Physician Fee Schedule rules also implemented a number of PPACA provisions, including the waiver
of beneficiary cost-sharing for certain preventive services covered under Medicare, such as screening mammograms and colonoscopies. Effective January 1, 2011, Medicare beneficiaries will no longer be required to satisfy their deductibles or pay
a copayment amount for these services. CMS states that by eliminating these out-of-pocket costs, beneficiaries will be encouraged to make full use of their Medicare preventive benefits. At this time, we cannot predict whether these changes will have
a material impact on the demand for our services and/or our future revenues.

Over the past few years, the growth rate of MRI
industry wide scan volumes has slowed in part due to weak hospital volumes as reported by several investor-owned hospital companies, additional patient-related cost-sharing programs and an increasing trend of third-party payors intensifying their
utilization management efforts, for example through benefit managers who require preauthorizations, to control the growth rate of imaging services generally. We expect that these trends will continue throughout the remainder of 2010 and into 2011.
Another recent initiative to potentially reduce utilization of certain imaging services, authorized under MIPPA, is the Medicare Imaging Demonstration, which is designed to collect data regarding physician use of advanced diagnostic imaging
services. This information would be used to determine the appropriateness of services by developing medical specialty guidelines for advanced imaging procedures within three designated modalities (MRI, CT and nuclear medicine). The demonstration is
scheduled to begin on January 1, 2011 and will operate for two years.

In addition, we cannot predict the full extent of
the PPACA on our business. The reform law substantially changes the way health care is financed by both governmental and private insurers. Although certain provisions may negatively impact payment rates for certain imaging services, the PPACA also
extends coverage to approximately 32 million previously uninsured people which may result in an increase in the demand for our services. Further, we cannot predict at this time whether other legislative changes will be adopted, if any, or how
these or future changes will affect the demand for our services.

We have experienced and continue to experience an increase
in the competitive climate in the MRI industry, resulting in an increase in activity by original equipment manufacturers, or OEMs, selling systems directly to certain of our clients, as well as medical groups. Typically, OEMs target our higher
scan volume clients. This increase in activity by OEMs has resulted in overcapacity of systems in the marketplace. This has caused an increase in the number of our higher scan volume clients deciding not to renew their contracts. We replace
lost higher volume clients typically with lower volume clients. Our non scan-based MRI business has been impacted by a decline in the number of hospital construction projects, driven by a decrease in new MRI systems being added by hospitals in their
facilities and a decrease in the number of equipment upgrades occurring in the hospital market. Additionally, a growing number of medical groups have added imaging capacity within their practice setting which further increases competition in the
industry. Our MRI revenues decreased in the first nine months of 2010 compared to 2009 due to the factors described above, and we believe that MRI revenues will continue to decline in future years.

Recent global market and economic conditions have been unprecedented and challenging with tighter credit conditions and recession in most
major economies which continued into 2010 and have not fully recovered. Continued concerns about the systemic impact of potential long-term and wide-spread recession, inflation, energy costs, geopolitical issues, the availability and cost of credit,
the United States mortgage market and a declining real estate market in the United States have contributed to increased market volatility and diminished expectations for the United States economy. Added concerns fueled by the United States
government financial assistance to certain companies and other federal governments interventions in the United States financial system have led to increased market uncertainty and instability in both United States and international capital and
credit markets. These conditions, combined with volatile oil prices, declining business and consumer confidence, increased unemployment, increased tax rates and governmental budget deficits and debt levels have contributed to volatility of
unprecedented levels. We believe our MRI and PET/CT scan volumes have been impacted during 2009 and the first nine months of 2010 and will continue to be impacted in the remainder of 2010 by high unemployment rates, the number of under-insured or
uninsured patients, the reported decline in physician office visits, hospitals adding imaging services in order to enhance hospital profitability and other conditions arising from the global economic conditions described above. At this time, it is
unclear what impact this might have on our future revenues or business.

As a result of these market conditions, the cost and
availability of credit has been and may continue to be adversely affected by illiquid credit markets and wider credit spreads. Concern about the stability of the markets generally and the strength of counterparties specifically has led many lenders
and institutional investors to reduce, and in some cases, cease to provide funding to borrowers. Continued turbulence in the United States and international markets and economies may adversely affect our liquidity and financial condition, and the
liquidity and financial condition of our customers. If these market conditions continue, they may limit our ability to timely access the capital markets to meet liquidity needs, resulting in adverse effects on our financial condition and results of
operations.

We perform an annual
impairment test for goodwill and indefinite life intangible assets based on financial information as of September 30, or more frequently when an event occurs or circumstances change that would more likely than not reduce the fair value of a
reporting unit below its carrying amount. We compare the fair value of our reporting units to their carrying amounts to determine if there is potential impairment. Significant judgment is required in the forecasts of future operating results that
are used in this evaluation. We base the fair value estimates on forecasted revenue and operating costs which include a number of factors including, but not limited to, securing new customers, retention of existing customers, growth in imaging and
radiation oncology revenues and the impact of continued cost savings initiatives. It is possible, however, that the plans may change and estimates used may prove to be inaccurate. If the actual results, or the plans and estimates used in future
impairment analyses, are lower than the original estimates used to assess the recoverability of these assets, we could incur an impairment charge. A significant decrease in our future market capitalization may also indicate that an impairment charge
may be incurred in connection with a future impairment test. In 2009 and the first nine months of 2010, we concluded that no impairment was present in goodwill or other intangible assets.

The principal components of our cost of revenues are compensation paid to technologists, radiation therapists and drivers, as well as
system maintenance costs, medical supplies, system transportation and technologists travel costs. Because a majority of these expenses are fixed, decreased revenues as a result of lower scan volumes or treatments per system significantly
impact our margins while higher scan volumes or treatments would result in improved margins.

The principal components of
selling, general and administrative expenses are sales and marketing costs, corporate overhead costs, provision for doubtful accounts, and share-based payment.

We record noncontrolling interest and earnings from unconsolidated investees related to our consolidated and unconsolidated subsidiaries, respectively. These subsidiaries primarily provide shared-service
and fixed-site diagnostic imaging and therapeutic services.

Seasonality

We experience seasonality in the revenues and margins generated for our services. First and fourth quarter revenues are typically lower
than those from the second and third quarters. First quarter revenue is affected primarily by fewer calendar days and inclement weather, typically resulting in fewer patients being scanned during the period. Fourth quarter revenues are affected by
holiday and client and patient vacation schedules, resulting in fewer scans during the period. The variability in margins is higher than the variability in revenues due to the fixed nature of our costs. We also experience fluctuations in the
revenues and margins generated due to acquisition activity and general economic conditions, including the high unemployment rate, recession or economic slowdown.

Results of Operations

The following table shows our consolidated
statements of operations as a percentage of revenues for each of the quarters and nine months ended September 30:

Quarter Ended
September 30, 2010 Compared to Quarter Ended September 30, 2009

Revenue decreased $3.1 million, or 2.5%, to
$121.1 million in the third quarter of 2010 compared to $124.2 million in the third quarter of 2009 due to a decrease in MRI revenues and PET/CT revenues, partially offset by an increase in radiation oncology revenues and other modalities
and other revenue. MRI revenue decreased $4.7 million in the third quarter of 2010, or 7.9%. Scan-based MRI revenue decreased $5.2 million in the third quarter of 2010, or 9.5%, compared to the third quarter of 2009, to $49.1 million
in the third quarter of 2010 from $54.3 million in the third quarter of 2009. Scan-based MRI scan volume decreased 8.8% to 128,913 scans in the third quarter of 2010 from 141,392 scans in the third quarter of 2009, primarily due to a decrease
in client demand, the increase in the unemployment rate during 2009, which persisted throughout the first nine months of 2010, and the related increase of uninsured and under-insured patients. Average scans per system per day decreased by 5.7% to
8.24 in the third quarter of 2010 from 8.74 in the third quarter of 2009. The average price per MRI scan decreased to $380.87 per scan in the third quarter of 2010 from $383.92 per scan in the third quarter of 2009. These decreases were partially
offset by an increase in the average number of scan-based systems in service, which increased to 242.1 systems in the third quarter of 2010 from 240.2 systems in the third quarter of 2009. Non scan-based MRI revenue increased $0.5 million in
the third quarter of 2010 over the same period in 2009. PET and PET/CT revenue in the third quarter of 2010 decreased $4.2 million, or 8.4%, compared to the third quarter of 2009. Total PET and PET/CT scan volumes decreased 4.4% to 43,401 scans
in the third quarter of 2010 from 45,415 scans in the third quarter of 2009, primarily due to a decrease in client demand, the increase in the unemployment rate during 2009, which persisted throughout the first nine months of 2010, and the related
increase of uninsured and under-insured patients. Scans per system per day decreased 4.9% to 5.59 scans per system per day in the third quarter of 2010 from 5.88 scans per system per day in the third quarter of 2009. The average price per PET and
PET/CT scan decreased to $1,047 per scan in the third quarter of 2010 compared to $1,089 per scan in the third quarter of 2009. The average number of PET and PET/CT systems in service decreased to 118.1 systems in the third quarter of 2010 from
119.2 systems in the third quarter of 2009. Radiation oncology revenue increased $2.9 million, or 32.3%, to $11.7 million in the third quarter of 2010 compared to $8.8 million in the third quarter of 2009, primarily due to an increase
in treatments performed in our core radiation oncology business and revenue related to the acquisition located in Pine Bluff, Arkansas (Pine Bluff). Other modalities and other revenue increased $2.9 million, or 42.7%, to
$9.5 million in the third quarter of 2010 compared to $6.6 million in the third quarter of 2009, primarily due to an increase in revenue related to the acquisition of Radiology 24/7, LLC (RAD 24/7). Included in the revenue
totals above is fixed-site imaging center revenues, which increased $2.6 million, or 9.5%, to $30.3 million in the third quarter of 2010 from $27.7 million in the third quarter of 2009.

We had 301 MRI systems at September 30, 2010, compared to 288 MRI systems at September 30, 2009. We had 125 PET and PET/CT
systems at September 30, 2010, compared to 126 PET and PET/CT systems at September 30, 2009. We operated 126 fixed-site imaging centers (including three in unconsolidated investees) at September 30, 2010, compared to 110 fixed-site
imaging centers (including three in unconsolidated investees) at September 30, 2009. We operated 26 radiation oncology centers (including two in unconsolidated investees) at September 30, 2010, compared to 23 radiation oncology centers
(including two in unconsolidated investees) at September 30, 2009.

Cost of revenues, excluding depreciation and
amortization, increased $0.8 million, or 1.2%, to $66.3 million in the third quarter of 2010 compared to $65.5 million in the third quarter of 2009. Outside medical services increased $2.4 million, or 91.3%, primarily as a result
of an increase in professional services related to the acquisition of RAD 24/7. License, taxes and other fees increased $0.4 million, or 54.9% primarily due to an increase in property taxes related to an increase in MRI systems in use.
Compensation and related employee expenses decreased $0.8 million, or 2.6%, primarily as a result of a decrease in average headcount. Medical supplies decreased $0.7 million, or 9.9%, primarily as a result of a decrease in the number of
PET and PET/CT scans, which use a radiopharmaceutical as a component of the PET and PET/CT scan. Equipment rental costs decreased $0.5 million, or 69.2%, primarily due to a lower number of rental systems in use to support current clients as a
result of improved system utilization. Cost of revenues, as a percentage of revenue, increased to 54.8% in the third quarter of 2010 from 52.7% in the third quarter of 2009 as a result of the factors described above.

Selling, general and administrative expenses increased $1.2 million, or 7.4%, to $16.9 million in the third quarter of 2010
compared to $15.7 million in the third quarter of 2009. Compensation and related employee expenses increased $1.2 million, or 13.6%, primarily as a result of investments in the infrastructure of the oncology division and professional
services. The provision for doubtful accounts increased $0.1 million, or 21.5%, due to an increase in the provision for doubtful accounts related to increased retail revenue generated from acquisitions completed in 2010. The provision for
doubtful accounts as a percentage of revenue was 0.3% in the third quarter of 2010 compared to 0.2% of revenue in the third quarter of 2009. All other selling, general and administrative expenses decreased $0.1 million, or 2.3%. Selling,
general and administrative expenses as a percentage of revenue were 14.0% and 12.7% in the third quarters of 2010 and 2009, respectively.

We recorded
transaction costs of $0.8 million in the third quarter of 2010 compared to $0.1 million in the third quarter of 2009.

We
recorded severance and related costs of $0.3 million in the third quarter of 2010 compared to $0.5 million in the third quarter of 2009.

Depreciation expense decreased $1.2 million, or 4.9%, to $23.0 million in the third quarter of 2010 compared to $24.2 million in the third quarter of 2009.

Amortization expense increased by $0.6 million, or 21.6%, to $3.3 million in the third quarter of 2010 compared to
$2.7 million in the third quarter of 2009, primarily due to the incremental amortization expense for intangible assets acquired in conjunction with our acquisitions in 2010.

Interest expense and other, net, increased $1.5 million, or 13.1%, to $12.6 million in the third quarter of 2010 compared to
$11.2 million in the third quarter of 2009, due to higher average interest rates on our credit facility and notes and $0.1 million expense from a non-cash fair value adjustment related to our interest rate swap agreements, which were
de-designated in 2009.

Income tax benefit was $0.8 million in the third quarter of 2010 compared to income tax expense
of $2.1 million in the third quarter of 2009, resulting in effective tax rates of 45.0% and 40.5% in the third quarters of 2010 and 2009, respectively. Income tax expense (benefit) for the quarters ended September 30, 2010 and 2009 were
based on estimated annual effective tax rates applied to pretax income (loss), adjusted for discrete items. Our effective tax rates differed from the federal statutory rate principally as a result of state income taxes and permanent non-deductible
tax items, including share-based payments, unrecognized tax benefits and other permanent differences.

Earnings from
unconsolidated investees decreased by $0.4 million, or 26.9%, to $0.9 million in the third quarter of 2010 compared to $1.3 million in the third quarter of 2009.

Nine Months Ended September 30, 2010 Compared to Nine Months Ended September 30, 2009

Revenue decreased $24.8 million, or 6.4%, to $361.2 million in the first nine months of 2010 compared to $386.0 million in
the first nine months of 2009 due to a decrease in MRI revenues and PET/CT revenues, partially offset by an increase in radiation oncology revenues and other modalities and other revenue. MRI revenue decreased $22.8 million in the first nine
months of 2010, or 12.4%. Scan-based MRI revenue decreased $21.8 million, or 13.0%, to $146.1 million in the first nine months of 2010 from $167.9 million in the first nine months of 2009. Scan-based MRI scan volume decreased 13.8% to
380,734 scans in the first nine months of 2010 from 441,886 scans in the first nine months of 2009, primarily due to a decrease in client demand, the increase in the unemployment rate during 2009, which persisted throughout the first nine months of
2010, and the related increase of uninsured and under-insured patients. Scan-based systems in service decreased to 236.9 systems in the first nine months of 2010 from 242.9 systems in the first nine months of 2009. Average scans per system per day
decreased by 8.0% to 8.29 in first nine months of 2010 from 9.01 in first nine months of 2009. These decreases were partially offset by an increase in the average price per MRI scan. The average price per MRI scan increased to $383.71 per scan in
the first nine months of 2010 from $379.99 per scan in the first nine months of 2009. Non scan-based MRI revenue decreased $1.0 million in the first nine months of 2010 over the same period in 2009 primarily due to a decline in the number of
hospital construction projects and a decrease in the number of equipment upgrades occurring in the hospital market, both of which impact the demand for our non scan-based MRI business. PET and PET/CT revenue in the first nine months of 2010
decreased $10.3 million, or 6.8%, compared to the first nine months of 2009. Total PET and PET/CT scan volumes decreased 2.9% to 132,201 scans in the first nine months of 2010 from 136,085 scans in the first nine months of 2009, primarily due
to a decrease in client demand, the increase in the unemployment rate during 2009, which persisted throughout the first nine months of 2010, and the related increase of uninsured and under-insured patients. The average price per PET and PET/CT scan
decreased to $1,063 per scan in the first nine months of 2010 compared to $1,105 per scan in the first nine months of 2009. Scans per system per day decreased 5.3%, to 5.70 scans per system per day in the first nine months of 2010 from 6.02 scans
per system per day in the first nine months of 2009. The average number of PET and PET/CT systems in service increased to 118.0 systems in the first nine months of 2010 from 115.2 systems in the first nine months of 2009. Radiation oncology revenue
increased $6.5 million, or 24.4%, to $32.9 million in the first nine months of 2010 compared to $26.4 million in the first nine months of 2009, primarily due to an increase in treatments performed in our core radiation oncology
business and revenue related to the Pine Bluff acquisition. Other modalities and other revenue increased

Earnings from
unconsolidated investees increased by $0.2 million, or 8.3%, to $2.9 million in the first nine months of 2010 compared to $2.7 million in the first nine months of 2009.

Net income attributable to noncontrolling interest increased $0.9 million, or 40.6%, to $2.9 million in the first nine months
of 2010 compared to $2.0 million in the first nine months of 2009.

Net loss attributable to Alliance HealthCare
Services, Inc. was $3.1 million, or $(0.06) per share on a diluted basis, in the first nine months of 2010 compared to net income of $11.5 million, or $0.22 per share on a diluted basis, in the first nine months of 2009.

Liquidity and Capital Resources

Our primary source of liquidity is cash provided by operating activities. We generated $85.1 million and $108.6 million of cash flow from operating activities in the nine months ended
September 30, 2010 and 2009, respectively. Our ability to generate cash flow is affected by numerous factors, including demand for MRI, PET/CT, other diagnostic imaging and radiation oncology services. Our ability to generate cash flow from
operating activities is also dependent upon the collections of our accounts receivable. The provision for doubtful accounts decreased by $1.4 million in the nine months ended September 30, 2010 compared to the nine months ended
September 30, 2009. Our number of days of revenue outstanding for our accounts receivable was 52 and 50 days as of September 30, 2010 and 2009, respectively, which we believe is favorable compared to other diagnostic imaging and
radiation oncology providers. In addition, as of September 30, 2010, we had $115.3 million of available borrowings under our revolving line of credit.

We used cash of $75.6 million and $42.7 million for investing activities in the nine months ended September 30, 2010 and 2009, respectively. Investing activities in the first nine months of
2010 and 2009 include $33.2 million and $0.8 million, respectively, which was used for acquisitions. Investing activities in the first nine months of 2010 and 2009 also include $0.5 million and $2.9 million, respectively, in cash
provided by a decrease in cash in escrow. We expect to continue to use cash for acquisitions in the future. Other than acquisitions, our primary use of capital resources is to fund capital expenditures. We incur capital expenditures for the purposes
of:



| |  |  | purchasing new systems;
| | - |  | -----------------------



| |  |  | replacing less advanced systems with new systems; and
| | - |  | -----------------------------------------------------



| |  |  | providing upgrades of our MRI, PET and PET/CT, and radiation oncology systems and upgrading our corporate infrastructure for future growth.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------

Capital expenditures totaled $43.8 million and $51.4 million in the nine months ended
September 30, 2010 and 2009, respectively. During the first nine months of 2010, we purchased 17 MRI systems and three PET/CT systems. We traded-in or sold a total of 23 systems for the nine months ended September 30, 2010. Our decision to
purchase a new system is typically predicated on obtaining new or extending existing client contracts, which serve as the basis of demand for the new system. We expect to purchase additional systems in 2010 and finance substantially all of these
purchases with our available cash, cash from operating activities, our revolving line of credit, and equipment leases. Based upon the client demand described above, which dictates the type of equipment purchased, we expect cash capital expenditures
to total approximately $55 to $65 million in 2010.

At September 30, 2010, we had cash and cash equivalents of
$103.6 million. This available cash and cash equivalents are held in accounts managed by third party financial institutions and consist of invested cash and cash in our operating accounts. The invested cash is invested in interest bearing funds
managed by third party financial institutions. These funds invest in high-quality money market instruments, primarily direct obligations of the government of the United States. To date, we have experienced no loss or lack of access to our invested
cash or cash equivalents; however, we can provide no assurances that access to our invested cash and cash equivalents will not be impacted by adverse conditions in the financial markets.

At September 30, 2010, we had $98.4 million in our accounts that are with third party financial institutions which exceed the
Federal Deposit Insurance Corporation (FDIC) insurance limits. While we monitor daily the cash balances in our operating accounts and adjust the cash balances as appropriate, these cash balances could be impacted if the underlying
financial institutions fail or could be subject to other adverse conditions in the financial markets. To date, we have experienced no loss or lack of access to cash in our operating accounts.

We believe that, based on current levels of operations, our cash flow from operating activities, together with other available sources of
liquidity, including borrowings available under our revolving line of credit, will be sufficient over the next one to two years to fund anticipated capital expenditures and potential acquisitions and make required payments of

principal and interest on our debt. As of September 30, 2010, we are in compliance with all covenants contained in our long-term debt agreements and expect that we will be in compliance with
these covenants for the remainder of 2010.

Recent Accounting Pronouncements

For a discussion of recent accounting pronouncements, please refer to Note 4 of the Notes to Condensed Consolidated Financial
Statements.

Cautionary Statement Pursuant to the Private Securities Litigation Reform Act of 1995

Certain statements contained in Managements Discussion and Analysis of Financial Condition and Results of Operations, particularly
in the sections entitled Overview, Results of Operations and Liquidity and Capital Resources, and elsewhere in this quarterly report on Form 10-Q, are forward-looking statements, within the
meaning of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Statements which address activities, events or developments that we expect or anticipate will or may occur in the future, including such things as results
of operations and financial condition, capital expenditures, economic trends, demand for our services, the consummation of acquisitions and financing transactions and the effect of such transactions on our business and our plans and objectives for
future operations and expansion, are examples of forward-looking statements. In some cases you can identify these statements by forward-looking words like may, will, should, expect, plan,
anticipate, believe, estimate, predict, seek, intend, and continue or similar words. These forward-looking statements are subject to risks and uncertainties which
could cause actual outcomes and results to differ materially from our expectations, forecasts and assumptions. These risks and uncertainties include factors affecting our leverage, including fluctuations in interest rates, the risk that the
counter-parties to our interest rate swap agreements fail to satisfy their obligations under these agreements, our ability to incur financing, the effect of operating and financial restrictions in our debt instruments, the accuracy of our estimates
regarding our capital requirements, the effect of intense levels of competition in our industry, fluctuations or unpredictability of our revenue, including as a result of seasonality, changes in the rates or methods of third party reimbursements for
diagnostic imaging and radiation oncology services, changes in the healthcare regulatory environment, our ability to keep pace with technological developments within our industry, the growth in the market for MRI and other services, the disruptive
effect of hurricanes and other natural disasters, adverse changes in general domestic and worldwide economic conditions and instability and disruption of credit markets, difficulties we may face in connection with recent, pending or future
acquisitions, including unexpected costs or liabilities resulting from acquisitions, diversion of managements attention from the operation of the business and our ability to integrate acquisitions, and other risks and uncertainties, including
those enumerated and described under Risk Factors below and in our Form 10-K, as filed with the Securities and Exchange Commission, for the fiscal year ended December 31, 2009 and in our Forms 10-Q, as filed with the Securities
and Exchange Commission for the quarters ended March 31, 2010 and June 30, 2010. The foregoing should not be construed as an exhaustive list of all factors which could cause actual results to differ materially from those expressed in
forward-looking statements made by us.



|ITEM 3. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|------- | ----------------------------------------------------------

We provide our services exclusively in the United States and receive payment for our services exclusively in United States dollars. As a result, our financial results are unlikely to be affected by
factors such as changes in foreign currency exchange rates or weak economic conditions in foreign markets.

Our interest
expense is sensitive to changes in the general level of interest rates in the United States, particularly because the majority of our indebtedness has interest rates which are variable. The recorded carrying amount of our long-term debt under our
New Credit Facility approximates fair value as these borrowings have variable rates that reflect currently available terms and conditions for similar debt. To decrease the risk associated with interest rate increases, we have entered into multiple
interest rate swap and cap agreements for a portion of our variable rate debt. These swaps and caps are designated as cash flow hedges of variable future cash flows associated with our long-term debt.

During the first quarter of 2008, we entered into two interest rate swap agreements, with notional amounts of $92.7 million each, to
hedge future cash interest payments associated with a portion of our variable rate bank debt (the 2008 swaps). Under the terms of these agreements, we receive three-month LIBOR and pay a fixed rate of 3.15%. The net effect of the hedges
was to record interest expense at a fixed rate of 5.65%, as the underlying debt incurred interest based on three-month LIBOR plus 2.50%. For the quarter and nine months ended September 30, 2009, we paid a net settlement amount of
$0.5 million and $0.9 million, respectively, on these swap agreements. The 2008 swaps are three years in length and mature in 2011. See below for additional information regarding the 2008 swaps. As discussed below, we elected to terminate
and replace one of the 2008 swaps in the first quarter of 2009.

On September 15,
2008, LHI filed for bankruptcy protection under Chapter 11 of the United States Bankruptcy Code. On October 6, 2008, LCPI filed for bankruptcy protection under Chapter 11 of the United States Bankruptcy Code. One of our 2008 swaps
with a notional amount of $92.7 million, which expires January 31, 2011, is with LCPI (the Lehman Swap). As of September 12, 2008, hedge accounting was terminated and all further changes in the fair market value of the
Lehman Swap are being recorded in interest expense and other. Comprehensive income (loss) related to effective unrealized gains or losses on the fair value of the Lehman Swap through September 12, 2008 remains in accumulated comprehensive
income (loss) on the balance sheet and will be amortized into interest expense and other as the underlying interest payments are recognized in earnings. The Lehman Swap was valued using the income approach with observable Level 2 market
expectations at the measurement date and standard valuation techniques to convert future amounts to a single discounted present amount. The fair market value of the Lehman Swap at September 30, 2008 was an asset of $0.7 million, which was
adjusted to zero as collectability was deemed uncertain due to the LHI bankruptcy filing. We included the write down of the asset in interest expense and other for the year ended December 31, 2008. For the last three quarters of 2008, we
included $2.4 million in interest expense and other, net related to the fair value adjustment for this swap as we did not expect LCPI to fulfill their obligations under the swap agreement. As a result, we terminated the Lehman Swap in February
2009. We paid $2.2 million for the remaining fair market value of the swap at the date of termination.

During the first
quarter of 2009, we replaced the Lehman Swap with an interest rate swap agreement which has a notional amount of $92.7 million (the 2009 Swap Replacement) and has been designated as a cash flow hedge of variable future cash flows
associated with a portion of our long term debt. Under the terms of this agreement, which matures in January 2011, we receive three-month LIBOR and pay a fixed rate of 3.15%. The net effect of the hedge is to record interest expense at a fixed rate
of 5.65%, as the debt incurs interest based on three-month LIBOR plus 2.50%. We received $2.2 million in cash based on the terms of the agreement. For the quarter and nine months ended September 30, 2010, we paid net settlement amounts of
$0.6 million and $2.0 million, respectively, on this swap agreement. For the quarter and nine months ended September 30, 2009, we paid net settlement amounts of $0.5 million and $0.9 million, respectively, on this swap agreement.

Additionally, during the first quarter of 2009, we entered into an interest rate swap agreement, which has a notional amount
of $56.8 million, to hedge future cash interest payments associated with a portion of our variable rate bank debt (the New 2009 Swap). Under the terms of this agreement, which was to mature in November 2011, we received three-month
LIBOR and paid a fixed rate of 2.07%. The net effect of the hedge was to record interest expense at a fixed rate of 4.57%, as the debt incurred interest based on three-month LIBOR plus 2.50%. For the quarter and nine months ended September 30,
2009, we paid net settlement amounts of $0.2 million and $0.3 million, respectively, on this swap agreement.

We elected
to terminate one of the 2008 swaps and the New 2009 Swap in December 2009 in connection with entering into the Refinance Transaction on December 1, 2009. As a result of the Refinance Transaction, we de-designated the 2008 swap, the 2009 Swap
Replacement and the New 2009 Swap and hedge accounting was terminated and all further changes in the fair market value of these swaps are being recorded in interest expense and other. We paid $3.3 million and $1.4 million for the remaining
fair market value of the 2008 swap and the New 2009 Swap, respectively, at the date of termination. Comprehensive income (loss) related to effective unrealized gains or losses on the fair value of these swaps through September 30, 2009 remain
in accumulated comprehensive income (loss) on the balance sheet and will be amortized into interest expense and other as the underlying interest payments are recognized in earnings. These swaps were valued using the income approach with observable
Level 2 market expectations at the measurement date and standard valuation techniques to convert future amounts to a single discounted present amount.

In the first quarter of 2010, we entered into one interest rate swap agreement (the 2010 Swap) and three interest rate cap agreements (the 2010 Caps) in order to avoid unplanned
volatility in the income statement due to changes in the LIBOR interest rate environment. The 2010 Swap, which matures in January 2011, has a notional amount of $92.7 million and synthetically unwinds the effects of the 2009 Swap Replacement.
For the quarter and nine months ended September 30, 2010, we received a net settlement amount of $0.1 million on this swap agreement. The interest rate cap agreements, which mature in February 2014, have a total notional amount of
$150.0 million and were designated as cash flow hedges of future cash interest payments associated with a portion of our variable rate bank debt. Under these arrangements we have purchased a cap on LIBOR at 4.50%. We paid $1.5 million to
enter into the caps, which is being amortized through interest expense over the life of the agreements. For the quarter and nine months ended September 30, 2010, we paid no net settlement amounts on the 2010 Swap or the 2010 Caps.

During the first
quarter of 2009, we entered into a diesel fuel swap agreement which had a notional quantity of 1,008,000 gallons, or 84,000 gallons per month, to hedge future cash payments associated with purchasing diesel fuel for our mobile fleet. Under the terms
of this agreement, which matured in February 2010, we received the Department of Energy published monthly average price per gallon and paid a fixed rate of two dollars and sixty-three cents per gallon. Settlement amounts under this swap were not
material for the nine months ended September 30, 2010 or for the quarter ended September 30, 2009. For the nine months ended September 30, 2009, we paid a net settlement amount of $0.1 million on this swap agreement. For the nine
months ended September 30, 2010, amounts recognized in other (income) and expense, net were not material. For the quarter and nine months ended September 30, 2009, amounts recognized in other (income) and expense, net were not material.

During the first quarter of 2010, we entered into a diesel fuel swap agreement which has a notional quantity of 1,008,000
gallons, or 84,000 gallons per month, to hedge future cash payments associated with purchasing diesel fuel for our mobile fleet. Under the terms of this agreement, which matures in February 2011, we receive the Department of Energy published monthly
average price per gallon and pays a fixed rate of three dollars and twenty-five cents per gallon. We designated this swap as a cash flow hedge of future cash flows associated with our diesel fuel payments. We record effective changes in the fair
value of the swap through comprehensive income (loss) and reclassify gains or losses to fuel expense (included in cost of revenues, excluding depreciation and amortization) when the underlying fuel is purchased. For the quarter and nine months ended
September 30, 2010, we paid net settlement amounts of $0.9 million on this swap agreement. For the quarter and nine months ended September 30, 2010, amounts recognized in other (income) and expense, net were not material.

Our interest income is sensitive to changes in the general level of interest rates in the United States, particularly because the
majority of our investments are in cash equivalents. We maintain our cash equivalents in financial instruments with original maturities of 90 days or less. Cash and cash equivalents are invested in interest bearing funds managed by third party
financial institutions. These funds invest in high-quality money market instruments, primarily direct obligations of the government of the United States. At September 30, 2010, we had cash and cash equivalents of $103.6 million, of which
$98.4 million was held in accounts that are with third party financial institutions which exceed the FDIC insurance limits. At September 30, 2009, we had cash and cash equivalents of $129.7 million, of which $124.5 million was
held in accounts that are with third party financial institutions which exceed the FDIC insurance limits.



|ITEM 4. | CONTROLS AND PROCEDURES
|------- | -----------------------

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Exchange Act
reports is recorded, processed, summarized and reported within the time periods specified in the SECs rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief
Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and
operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Also, we have
investments in certain unconsolidated entities. As we do not control or manage these entities, our disclosure controls and procedures with respect to such entities are more limited than those we maintain with respect to our consolidated
subsidiaries. These unconsolidated entities are not considered material to our consolidated financial position or results of operations.

As required by SEC Rule 13a-15(b), 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 the design and operation of our disclosure controls and procedures as of the end of the period covered by this report. Based on the foregoing, our Chief Executive Officer and Chief Financial Officer concluded that our
disclosure controls and procedures were effective at the reasonable assurance level.

There has been no change in our internal
control over financial reporting during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART IIOTHER INFORMATION



|ITEM 1. | LEGAL PROCEEDINGS
|------- | -----------------

From
time to time, we are involved in routine litigation incidental to the conduct of our business. We believe that none of this litigation pending against us will have a material adverse effect on our business.

In connection with our acquisition of Medical Outsourcing Services, LLC (MOS) in the third quarter of 2008, we
subsequently identified a Medicare billing practice related to a portion of MOSs retail billing operations that raised compliance issues under Medicare reimbursement guidelines. The practice was in place prior to the acquisition and was
discontinued when we became aware of it. In accordance with our corporate compliance program, we have entered into discussions with representatives of the federal government to advise them of the issue and seek guidance on appropriate next steps.
The discussions are ongoing and no resolution has yet been reached. Although the government may seek repayment and penalties relating to the billing practice, we do not expect that such repayment and penalties, if imposed on us, would have a
material impact on our results of operations, cash flows or financial position because we believe the amounts we would owe will be substantially or fully off-set by recoveries under the indemnification provisions of the MOS acquisition purchase
agreement. Pursuant to the terms of the purchase agreement, in June 2010 we commenced arbitration proceedings related to this matter.



|ITEM 1A. | RISK FACTORS
|-------- | ------------

The Company
has included in Part I, Item 1A of its Annual Report on Form 10-K for the year ended December 31, 2009, and in Part II, Item 1A of its Quarterly Reports on Form 10-Q for the quarters ended March 31, 2010 and
June 30, 2010, a description of risks and uncertainties that could affect the Companys business, future performance or financial condition (the Risk Factors). The Risk Factors, as modified below, are hereby incorporated in
Part II, Item 1A of this Form 10-Q. Investors should consider the Risk Factors prior to making an investment decision with respect to the Companys stock.

Changes in the rates or methods of third-party reimbursements for diagnostic imaging services could result in reduced demand for our services or create downward pricing pressure, which would result
in a decline in our revenues and harm to our financial position.

We derive approximately 19% of our revenues from
direct billings to patients and third-party payors such as Medicare, Medicaid or private health insurance companies, and changes in the rates or methods of reimbursement for the services we provide could have a significant negative impact on those
revenues. Moreover, our healthcare provider clients on whom we depend for the majority of our revenues generally rely on reimbursement from third-party payors. If our clients receive decreased reimbursement, this could result in a reduced demand for
our services or downward pricing pressures, which could have a material impact on our financial position.

With respect to our
retail business, for services for which we bill Medicare directly, we are paid under the Medicare Physician Fee Schedule, which is updated on an annual basis. Under the Medicare statutory formula, payments under the Physician Fee Schedule would have
decreased for the past several years if Congress failed to intervene. For 2010, the Centers for Medicare and Medicaid Services (CMS) projected a rate reduction of 21.2% under the statutory formula unless Congress intervened again to
avoid the payment reduction. A number of legislative initiatives have prevented this reduction thus far, but on an incremental basis. The latest was the Preservation of Access to Care for Medicare Beneficiaries and Pension Relief Act of 2010, signed
into law on June 25, 2010, which not only prevented the rate reduction, but also increased payment rates by 2.2%, effective June 1, 2010 through November 30, 2010. These payment rates are currently scheduled to be reduced under the
statutory formula on December 1, 2010 and then again on January 1, 2011. CMS is currently projecting that the total reduction in payment rates will be 24.9%. If Congress fails to intervene to prevent the negative update factor in the future, the
resulting decrease in payment will adversely impact our revenues and results of operations.

For retail services furnished on
or after July 1, 2010, CMS began implementing a 50% reduction in reimbursement for multiple images on contiguous body parts, as mandated by the recently enacted Patient Protection and Affordable Care Act, as amended by the Health Care and
Education Affordability Reconciliation Act (collectively, the PPACA). This is a 25% increase from prior years. In its final Medicare Physician Fee Schedule rule for calendar year 2011, effective January 1, 2011, CMS will apply the same
reduction to certain CT and CT angiography (CTA), MRI and MR angiography (MRA), and ultrasound services furnished to the same patient in the same session, regardless of the imaging modality, and not limited to contiguous body
areas. CMS projects that the final rule will reduce payment for 20% more services than the current multiple procedure payment reduction policy. CMS expects that the final rule will primarily reduce payments for radiology services and to freestanding
diagnostic imaging centers, such as our retail business. At this time, we do not believe that the multiple procedure payment reductions will have a material impact on our future retail revenues.

##### Table of Contents



Regulatory updates to
the Physician Fee Schedule for calendar year 2010 include reduced payment rates for certain diagnostic services using equipment costing more than $1 million through revisions to usage assumptions from the previous 50% usage rate to a 90% usage rate.
This utilization change, to be phased in over a four-year period, applies to MRI and CT scans, but not for radiation therapy and other therapeutic equipment. The PPACA superseded CMSs assumed usage rate for such equipment and, beginning on
January 1, 2011, the PPACA requires CMS to use a 75% utilization rate. For 2011, CMS also finalized its proposed rule to expand the list of services to which the higher equipment utilization rate assumption applies to include certain diagnostic
CTA and MRA procedures using similar CT and MRI scanners that cost more than $1 million. At this time, we estimate that the new usage assumptions for MRI and CT scans under the PPACA, which is to take effect on January 1, 2011, will not have a
material impact on our future retail revenues.

Other regulatory changes to the 2010 Medicare Physician Fee Schedule involve
revaluing certain components of the fee schedule payment rate, which impact radiology and other diagnostic tests, including the services we provide. Some of these changes are being transitioned over a four year period, with full implementation in
2013. For the 2010 transition payment, CMS estimated that the aggregate impact of its changes (which include the changes in the equipment utilization rate discussed above) results in a 1% reduction in radiation oncology, 5% reduction in radiology,
18% reduction in nuclear medicine and 12% reduction for all suppliers providing the technical component of diagnostic tests generally. To date these changes have not had a material impact on our retail revenues. Effective January 1,
2011, CMS made further adjustments to the fee schedule so that specialties that have a higher proportion of the payment rate attributable to operating expenses such as equipment and supplies, which include radiation oncology, will experience an
increase in aggregate payments. In addition, as a result of adjustments to codes identified to be misvalued, radiation oncology specialties and suppliers providing the technical component of diagnostic tests are among the entities that will
experience decreases in aggregate payment. Some of these changes will be transitioned, and CMS estimates that the impact for 2011 (which include the changes in the equipment utilization rate discussed above as well as the expanded multiple procedure
payment reductions for certain imaging services) will be a 1% reduction in radiation oncology, 10% reduction in radiology, 4% reduction in nuclear medicine and 15% reduction for all suppliers providing the technical component of diagnostic tests
generally. These estimated impacts are calculated prior to the application of the negative update factor discussed above. At this time, we do not believe that the regulatory changes will have a material impact on our future retail revenues.

In addition to annual updates to the Medicare Physician Fee Schedule, as indicated above, CMS also publishes regulatory
changes to the hospital outpatient prospective payment system (HOPPS) on an annual basis. These payments are the amounts received by our hospital clients for hospital outpatient services and summarized in the table below:

The PET and PET/CT Medicare HOPPS rate reductions did not have a material negative effect on revenue and earnings in 2008,
2009 or the first nine months of 2010. At this time, however, we cannot predict the impact the rate reductions will have on our future revenues or business.

The 2011 HOPPS and Medicare Physician Fee Schedule rules also implemented a number of PPACA provisions, including the waiver of beneficiary cost-sharing for certain preventive services covered under
Medicare, such as screening mammograms and colonoscopies. Effective January 1, 2011, Medicare beneficiaries will no longer be required to satisfy their deductibles or pay a copayment amount for these services. CMS states that by eliminating
these out-of-pocket costs, beneficiaries will be encouraged to make full use of their Medicare preventive benefits. At this time, we cannot predict whether these changes will have a material impact on the demand for our services and/or our future
revenues.

Over the past few years, the growth rate of MRI industry wide scan volumes has slowed in part due to weak hospital
volumes as reported by several investor-owned hospital companies, a growing number of medical groups adding imaging capacity within their practice setting and additional patient-related cost-sharing programs. In addition, there is an increasing
trend of third-party payors intensifying their utilization management efforts, for example through benefit managers who require preauthorizations, to control the growth rate of imaging services generally. We expect that these trends will continue
throughout 2010. Another recent initiative to potentially reduce utilization of certain imaging services, authorized under MIPPA, is the Medicare Imaging Demonstration, which is designed to collect data regarding physician use of advanced diagnostic
imaging services. This information would be used to determine the appropriateness of services by developing medical specialty guidelines for advanced imaging procedures within three designated modalities (MRI, CT and nuclear medicine). The
demonstration is scheduled to begin on January 1, 2011 and will operate for two years.

In addition, we cannot
predict the full extent of the PPACA on our business. The reform law substantially changes the way health care is financed by both governmental and private insurers. Although certain provisions may negatively impact payment rates for certain imaging
services, the PPACA also extends coverage to approximately 32 million previously uninsured people which may result in an increase in the demand for our services. Further, we cannot predict at this time whether other legislative changes will be
adopted, if any, or how these or future changes will affect the demand for our services.
