NIGHTHAWK RADIOLOGY HOLDINGS, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of PresentationThe accompanying unaudited condensed consolidated financial statements include the results of
operations, financial position and cash flows of NightHawk Radiology Holdings, Inc. and its subsidiaries (the Company). All material intercompany balances have been eliminated.

In the opinion of the Companys management, the accompanying unaudited condensed consolidated financial statements include all
adjustments necessary to present fairly, in all material respects, the Companys results for the periods presented. These condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the
Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States
(GAAP) have been condensed or omitted pursuant to such SEC rules and regulations. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and accompanying notes
included in Item 8 of the Companys 2009 Annual Report on Form 10-K filed with the SEC on February 25, 2010. The results of operations for the three and nine months ended September 30, 2010 are not necessarily indicative of
results to be expected for the entire fiscal year.

On June 30, 2010, the Company settled a dispute with St. Paul
Radiology, P.A. (SPRPA). In connection with the settlement, the Company sold to a third party its ownership interest in Midwest Physicians Services, LLC (MPS) and Emergency Radiology Services, LLC (ERS).
Consequently, for all of the periods presented, income (loss) from these operations has been presented as net income (loss) from discontinued operations in the consolidated statements of operations. The assets and liabilities associated with MPS and
ERS have been reclassified to assets of discontinued operations and liabilities of discontinued operations as of December 31, 2009 on our accompanying consolidated balance sheet. Unless noted otherwise, discussions in these notes pertain to our
continuing operations only. For more information on the closing of the transaction, see also Note 12Discontinued Operations.

The Companys unaudited condensed consolidated balance sheet as of December 31, 2009 has been derived from the audited consolidated balance sheet as of that date. Certain information and
footnote disclosure normally included in the Companys annual consolidated financial statements have been condensed or omitted.

Use of EstimatesThe preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of
assets, liabilities, and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Some of these estimates require difficult, subjective or
complex judgments about matters that are inherently uncertain. Actual results could differ from those estimates.

On an
ongoing basis, the Company evaluates its estimates, including those related to the accounts receivable allowance, fair value of acquired intangible assets, useful lives of intangible assets and property and equipment, income taxes, the loss
contingency for general and medical liability claims, reserves for lease abandonment costs, reserves for incurred but not reported (IBNR) medical liability claims and for determining stock-based compensation.

Trade Accounts ReceivableTrade accounts receivable represent receivables for services and are recorded at the
invoiced amount and are non-interest bearing. Company management reviews past due accounts receivable to identify specific customers with known disputes or collectability issues. As of September 30, 2010 and December 31, 2009, the Company
had reserved $0.5 million and $0.9 million, respectively, for doubtful accounts based on its estimate of the collectability of outstanding receivables as of those dates. When the Company determines that a receivable is not recoverable, the amount is
removed from the financial records along with the corresponding reserve balance. During the three and nine months ended September 30, 2010, the Company removed $0.2 million and $0.7 million, respectively, of specifically identified
uncollectible accounts receivable and the corresponding reserves from its financial records.

Notes
ReceivableNotes receivable represents a $14.0 million promissory note issued by SPRPA to the Company as partial consideration for the settlement. The note does not bear interest and pursuant to the terms of the note, SPRPA is obligated
to make 48 equal installment payments of $250,000 starting in August 2010 and continuing to July 2014, and an additional payment of $2.0 million on or before March 31, 2011. Pursuant to the InterestTopic of the Financial Accounting
Standards Board (FASB) Accounting Standards Codification (ASC) (ASC Topic 835), the Company recorded the note on its balance sheet at the present value of future cash flows using an imputed interest rate. The resulting
difference between the par value of the note and the present value was a discount of $1.2 million, which is being amortized to interest income using the effective interest method.

Marketable SecuritiesThe Company determines the appropriate classification of investments in marketable debt and
equity securities at the time of purchase and reevaluates such designation at each balance sheet date. Marketable debt and equity securities have

been classified and accounted for as available for sale. The Company may or may not hold securities with stated maturities greater than 12 months until maturity. In response to changes in the
availability of and the yield on alternative investments as well as liquidity requirements, the Company occasionally sells these securities prior to their stated maturities. The Company primarily invests in high-credit-quality debt instruments with
an active resale market and money market funds to ensure liquidity and the ability to readily convert these investments into cash to fund current operations, or satisfy other cash requirements as needed. Accordingly, all marketable securities have
been classified as current assets in the accompanying balance sheets. These securities are carried at fair value, with the unrealized gains and losses, net of taxes, reported as a component of stockholders equity, except for unrealized losses
determined to be other than temporary which would be recorded as other expense. Any realized gains or losses on the sale of marketable securities are determined on a specific identification method, and such gains and losses are reflected as a
component of other income or expense.

Property and EquipmentProperty and equipment are stated at cost.
Depreciation is provided using the straight-line method over the estimated useful lives of each asset, which range as follows:

Expenditures for maintenance and repairs are charged to operating expense as incurred and expenditures for renewals and betterments are capitalized. Upon sale or retirement of depreciable assets, the
related cost and accumulated depreciation are removed from the records and any gain or loss is reflected in operating expenses.

The cost of computer software developed for internal use is capitalized and accounted for in accordance with the Intangibles-Goodwill
and OtherTopic of FASB Accounting Standards Codification (ASC Topic 350), Subtopic 40 Internal-Use Software. Capitalized costs are amortized based on their expected useful lives.

Depreciation expense for the three months ended September 30, 2010 and 2009 was $0.9 million and $0.8 million, respectively, and
$2.8 million and $2.4 million for the nine months ended September 30, 2010 and 2009, respectively.

ContingenciesThe Company records a loss contingency for legal claims at the time the Company deems such liability to
be probable. The determination of the probability of the liability is based upon a review of the claim by the Companys internal legal counsel, external legal counsel and, in the case of medical liability claims, the Companys medical
liability insurance carrier. Upon the determination that a liability is probable, the Company records a loss contingency for the estimated potential claim. Actual future losses from these legal claims may differ from the Companys estimates to
the extent that the Company suffers an adverse determination for a claim which the Company did not deem the liability probable, did not record a sufficient loss contingency, the loss was in excess of applicable insurance limits, or in the event that
the Company does not have insurance coverage or indemnification rights covering the specific claim.

Medical Liability
InsuranceThe Company is exposed to various risks of loss related to litigation that may arise related to malpractice and maintains insurance for medical liabilities in amounts considered adequate by Company management. The
Companys claims-made policy provides coverage up to the policy limits for claims filed within the period of the policy term, subject to deductible requirements and coverage limits. Coverage for affiliated radiologists is initiated when they
begin providing services on behalf of the Company.

The Company records reserves for both asserted and IBNR amounts. Asserted
claims are reserved based upon the Companys best estimate of future probable costs in accordance with the ContingenciesTopic of the FASB Accounting Standards Codification (ASC Topic 450). The IBNR reserve is intended to cover potential
medical claims that might arise related to past medical services performed by the Companys affiliated radiologists which have not yet been asserted. IBNR amounts are estimated using historical claims information and actuarial-based analyses.

Long-Lived
Assets Including Goodwill and Other Acquired Intangible AssetsUnder the provisions of the Intangibles-Goodwill and Other Topic of the FASB Accounting Standards Codification (ASC Topic 350), certain intangible assets are
amortized over their estimated useful lives. The Company currently has no goodwill on its balance sheet. Unamortized intangible assets are evaluated for impairment at least annually or more frequently if events and circumstances indicate that the
goodwill and intangible assets might be impaired.

In accordance with the Property, Plant, and EquipmentTopic of the
FASB Accounting Standards Codification (ASC Topic 360), the Company periodically reviews long-lived assets for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully
recoverable or that the useful lives of those assets are no longer appropriate. The Company performs impairment tests using discounted cash flows, valuation analyses or comparisons to recent sales or purchase transactions to determine estimated fair
value. If impairment is indicated, the asset is written down to its estimated fair value.

Concentration of Credit
RiskFinancial instruments that potentially expose the Company to concentration of credit risk consist primarily of cash, cash equivalents, marketable securities and accounts receivable. The Company maintains its cash, cash equivalents
and marketable securities with high-credit-quality institutions. As of September 30, 2010 and December 31, 2009, a total of $25.0 million and $26.2 million, respectively, of cash and cash equivalents exceeded federal government insured
amounts. In addition, as of September 30, 2010, the Company has a note receivable of $12.4 million from St. Paul Radiology, P.A.

Recently Issued Accounting StandardsIn January 2010, the FASB issued Accounting Standards Update (ASU) No. 2010-06. This ASU amended the Fair Value
Measurements and Disclosures Topic of the FASB Accounting Standards Codification (ASC Topic 820), 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. It also clarifies existing fair value disclosures about the level of disaggregation and about inputs and valuation techniques used to measure fair value. The ASU is effective
January 1, 2010, except for the requirement to provide the separate disclosures relating to Level 3 measurements noted above. That amendment is effective January 1, 2011. The impact of adopting the portion of the ASU related to Level 1 and
2 measurements was not significant. See Note 10Fair Value Measurements for the Companys recurring and non-recurring fair value disclosures, as required by ASC Topic 820.

In July 2010, the FASB issued ASU No. 2010-20. This ASU amended the Receivables Topic of the FASB Accounting Standards
Codification (ASC Topic 310). The update is intended to provide additional information to assist financial statement users in assessing an entitys credit risk exposures and evaluating the adequacy of its allowance for credit losses. The
amendment is effective for interim or annual periods ending on or after December 15, 2010. The Company does not believe that the impact of adopting this ASU will be significant.

In August 2010, the FASB issued ASU No. 2010-24. This ASU amended the Health Care Entities Topic of the FASB Accounting
Standards Codification (ASC Topic 954). The update provides clarification that a health care entity may not net insurance recoveries against related claim liabilities. The FASB also clarified that the amount of the claim liability must be determined
without consideration of insurance recoveries. The amendment is effective for interim or annual periods beginning after December 15, 2010. The Company has not yet determined the impact of adopting this ASU.

2. MARKETABLE SECURITIES

Marketable securities include various available-for-sale securities. These securities are carried at fair value, with the unrealized gains
and losses, net of taxes, reported as a component of stockholders equity. Gross unrealized gains and losses on marketable securities were not significant at September 30, 2010 or December 31, 2009.

Below are the Companys marketable securities at fair value:



|                                              |  |                    |   |  |                   |   |       |

3. INTANGIBLE ASSETS SUBJECT TO AMORTIZATION

The Company amortizes its intangible assets using the straight-line method over their estimated useful lives. As required by the Intangibles-Goodwill and OtherTopic of the FASB Accounting
Standards Codification (ASC Topic 350), an interim test for impairment must be performed whenever impairment indicators are present. The Companys intangible assets included, in part, those assets acquired as part of the Companys July
2007 acquisition of MPS and ERS from SPRPA and the related agreements entered into between the Company and SPRPA. As previously disclosed the Company and SPRPA were engaged in a dispute regarding those agreements and reached a settlement on
June 30, 2010 pursuant to which those agreements were terminated.

As a result of the
dispute and the Companys negotiations with SPRPA that were being held in the first quarter of 2010, as of March 31, 2010, the Company determined that an impairment indicator was present related to the intangible assets acquired from
SPRPA. As part of its analysis, the Company concluded that $27.3 million of the $49.6 million carrying value of these intangible assets were impaired. As a result, the Company recorded a non-cash intangible impairment charge of $27.3 million in the
three months ended March 31, 2010. On June 30, 2010, the Company entered into a series of agreements with SPRPA, its affiliates and a third party pursuant to which the dispute was settled. As a result of the transactions, the Company and
SPRPA terminated their prior agreements and the Company received consideration equal to the then remaining carrying value of the customer contract intangible asset associated with SPRPA.

A summary of intangible assets is as follows:

4. LONG-TERM DEBT

The Company has outstanding a fully syndicated term loan (the Term Loan) pursuant to which the Company has $51.7 million in outstanding borrowings as of September 30, 2010. The Term Loan
is required to be repaid in quarterly installments equal to approximately $0.1 million (such amount is subject to adjustment from time to time as a result of voluntary principal payments made by the Company) with the remaining balance due in a
single payment on the maturity date of July 10, 2014.

Interest under the Term Loan is based, at the option of the
Company, on either: (i) a floating per annum rate based on the higher of the prime rate or the fed funds rate plus 0.50% or (ii) a floating per annum rate (based upon one, two, three or six-month interest periods), which the Company has
chosen, based on three-month LIBOR plus 2.50% (2.79% at September 30, 2010). The Company entered into five interest rate swap contracts during 2008 which maintained a fixed effective interest rate on the Term Loan of approximately 4.95%. During
the three months ended September 30, 2010, the Company terminated all of these interest rate swap contracts.

The credit
agreement governing the Term Loan contains customary covenants and restrictions and is guaranteed by certain of the Companys wholly owned operating subsidiaries, including NightHawk Radiology Services, LLC, the Companys primary operating
entity, and is collateralized by substantially all of the Companys assets.

The Term Loan is subject to mandatory
repayment under certain circumstances, including in connection with the closing of the Companys potential merger with Virtual Radiologic Corporation (vRad) (see Note 13-Proposed Merger), the Companys receipt of proceeds from
certain issuances of equity or debt, sales of assets and casualty events. In addition, the credit agreement requires a principal payment in the amount equal to 50% of the Companys Excess Cash Flow as defined in the Companys loan
agreement if the Total Leverage Ratio as defined in the credit agreement is at or above 2.50 at year end. In connection with the settlement with SPRPA, the



10

(unaudited)



Company was required to obtain the consent of the lenders of the Term Loan and agreed to pay $26.0 million of the Term Loan on the day of the settlement and make an additional payment of $10.0
million on or prior to June 30, 2011. Pursuant to such consent, should the Company be required to make an Excess Cash Flow payment with respect to fiscal years 2010 and 2011, such Excess Cash Flow Payment will be reduced by an amount equal to
such repayments.

The credit agreement also contains customary affirmative, negative and financial covenants, including, among
other requirements, negative covenants that restrict the Companys ability to create liens, enter into mergers and acquisitions, pay dividends, repurchase stock, incur indebtedness, make investments and capital expenditures, and financial
covenants that limit the maximum leverage the Company can maintain at any one time. The maximum Total Leverage Ratio allowed under the terms of the loan is below 4.00 as measured on a trailing four quarter basis. The Total Leverage Ratio
excludes non-cash charges such as goodwill and intangible impairment charges and stock compensation. In addition, pursuant to the terms of the Companys credit agreement, the Company is required to calculate its Total Leverage Ratio on a pro
forma basis, meaning that the Company must calculate its Total Leverage Ratio assuming the SPRPA settlement transaction took place at the beginning of the trailing four quarter measurement period. As of September 30, 2010, the
Companys Total Leverage Ratio was 3.54. As of September 30, 2010, the Company was in compliance with all covenants contained in the credit agreement.

The Term Loan may be voluntarily repaid without premium or penalty. The Company made required principal payments of $0.5 million on the Term Loan during the nine months ended September 30, 2010
and as described above, the Company made a principal payment of $26 million immediately following the closing of transaction on June 30, 2010 and will make an additional principal payment of $10 million on or before June 30, 2011 in
connection with the settlement between the Company and SPRPA. For more information on the effects of such settlement, see also Note 3Intangible Assets Subject to Amortization.

As of September 30, 2010, the fair value of long-term debt, including the current portion, is estimated to be approximately $46.5
million.

5. COMMITMENTS AND CONTINGENCIES

LitigationThe Company is involved in litigation in the normal course of business. After consultation with legal counsel, Company management estimates that at September 30, 2010
these matters were expected to be resolved without material adverse effect on the Companys financial position, results of operations, or cash flows.

Securities Class Action and Related Derivative ClaimOn December 17, 2009, a putative shareholder class action lawsuit was filed against the Company and certain of its former
officers in the U.S. District Court for the District of Idaho. The case is captioned City of Marysville General Employees Retirement System v. NightHawk Radiology Holdings, Inc., et al., Case No. CIV 09-659-N-CWD. On July 13,
2010, plaintiffs filed an amended complaint under the new caption In re Nighthawk Radiology Holdings, Inc. Securities Litigation, Master File No. 09-cv-00659 (EJL/CWD). The complaint purports to be brought on behalf of a class of persons
who purchased or otherwise acquired the Companys stock during the period May 2, 2007 to May 7, 2008, and asserts claims under Section 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5 promulgated
thereunder. Plaintiffs contend that the Company and the individual defendants violated the federal securities laws by issuing false and misleading statements concerning the Companys operations, business, and prospects during the purported
class period, and thereby artificially increased the price of the Companys stock. Plaintiffs seek unspecified compensatory damages, interest, and attorneys fees and costs. On April 29, 2010, the court issued an order appointing
Plymouth County Contributory Retirement System (Plymouth) as lead plaintiff. On May 13, 2010, competing plaintiff Miramar Firefighters Pension Fund (Miramar) filed an objection to the courts appointment of
Plymouth as lead plaintiff and requested that the court instead appoint Miramar as lead plaintiff. The court has yet to rule on that motion. Pending the courts ruling on this objection, all deadlines have been taken off calendar, including
defendants deadline to respond to the complaint. Management intends to vigorously defend against these claims.

In
connection with the securities class action described above, on September 2, 2010, a shareholder derivative lawsuit was also filed in the U.S. District Court for the District of Idaho, purportedly on behalf of and for the benefit of the
Company, against certain of the Companys current and former officers and directors. The case is related to the securities class action case and is captioned Israni v. Berger, et al., Case No. 10-cv-00450-BLW. On September 8,
2010, a similar shareholder derivative lawsuit was filed in Kootenai County District Court. This lawsuit is captioned Jarrett v. Berger, et al. 10-7752. The Company is named as a nominal defendant in both lawsuits. The derivative complaint is
premised on the same basic allegations of fact as the securities class action and alleges, among other things, that certain of the Companys current and former officers and directors breached their fiduciary duties to the Company and were
unjustly enriched in connection with the public disclosures that are the subject of the securities class action. Because these lawsuits are derivative in nature, they do not seek monetary damages from the Company. The Company, however, may be
required through the pendency of these lawsuits to advance the legal fees and costs of the defendant officers and directors.

Merger
LitigationIn connection with the Companys announcement of its merger agreement with vRad (see Note 13-Proposed Merger), beginning on September 28, 2010, several putative class action lawsuits were filed purportedly on behalf
of the Companys stockholders in the Superior Court of Maricopa County, Arizona, docketed as Israni v. NightHawk Radiology Holdings, Inc., et al., Case No. CV2010-025059, LaLone v. NightHawk Radiology Holdings, Inc., et al., Case
No. CV2010-028112, La Torre v. NightHawk Radiology Holdings, Inc., et al., Case No. CV2010-028176, Watts v. Engert, et al., Case No. CV2010-028127, Newman v. Engert, et al., Case No. CV2010-028262, and Yu v. Engert, et
al., Case No. CV2010-028403. On October 8, 2010, a purported class action lawsuit on behalf of the Companys stockholders was filed in Delaware Chancery Court, docketed as Scully v. NightHawk Radiology Holdings, Inc., et al.,
Case No. 5890-VCL. The complaints name the Company, each of the members of the Companys board of directors, and vRad as defendants. The lawsuits allege, among other things, that the Companys board of directors breached fiduciary
duties owed to the Companys stockholders by failing to take steps to maximize stockholder value or to engage in a fair sale process when approving the proposed merger with vRad. The complaints also allege that the Company and vRad aided and
abetted the members of our board of directors in the alleged breach of their fiduciary duties. In the Delaware action, the plaintiff also alleges that the Companys preliminary proxy statement contains certain material omissions, rendering some
statements therein misleading. The plaintiffs in these various actions seek relief that includes, among other things, an injunction prohibiting the consummation of the proposed merger, a court order declaring that the board of directors breached
their fiduciary duties in entering into the merger agreement, rescission  to the extent the merger terms have already been implemented, and the payment of plaintiffs attorneys fees and costs. The Company believes the lawsuits to be
without merit and intends to defend against them vigorously. There can be no assurance, however, with regard to the outcome of these lawsuits.

Medical LiabilityIn addition to the litigation matters described above, the Company is also exposed to various risks of loss related to litigation that may arise related to medical
malpractice claims. The Company maintains insurance for medical liabilities in amounts considered adequate by Company management. The Companys claims-made policy provides coverage up to the policy limits for claims filed within the period of
the policy term, subject to deductible requirements. Coverage for affiliated radiologists is initiated when they begin providing services on behalf of the Company.

The Company records reserves for both asserted legal claims (medical liability and otherwise) as well as IBNR amounts for incurred but not reported medical liability claims. Asserted claims are reserved
based upon the Companys best estimate of future probable loss in accordance with the ContingenciesTopic of the FASB Accounting Standards Codification (ASC Topic 450). The IBNR reserve is intended to cover potential medical claims that
might arise related to past medical services performed by the Companys affiliated radiologists which have not yet been asserted. IBNR amounts are estimated using historical claims information and actuarial-based industry indices. During
the nine months ended September 30, 2010 and 2009, the Company recorded a credit adjustment of $0.9 million and an expense of $0.5 million, respectively, for estimated IBNR amounts. IBNR amounts, recorded as insurance reserve on the balance
sheet at September 30, 2010 and December 31, 2009 totaled $3.1 million and $4.0 million, respectively.

6. STOCK COMPENSATION
PLANS

Stock-Based Award PlansThe Company has two stock-based award plans, the 2004 Stock Plan (the
2004 Plan) and the 2006 Equity Incentive Plan (the 2006 Plan). In February 2006, all shares available for grant under the 2004 Plan were rolled over and became available for grant under the 2006 Plan. In addition, on the
first day of each fiscal year beginning in 2007, the number of shares available for issuance under the 2006 Plan may be increased by an amount equal to the lesser of (i) 3% of the outstanding shares of the Companys common stock on the
first day of the fiscal year and (ii) such other amount as the Companys board of directors may determine. As of September 30, 2010, the Company had an aggregate of 5,426,070 shares of its common stock reserved for issuance under the
2004 Plan and 2006 Plan. Of these shares, 1,166,238 shares were available for future grants and 4,259,832 shares were subject to outstanding stock awards as of September 30, 2010.

The Companys board of directors administers the plans, establishes to whom the awards are granted, and sets the terms and
conditions, including the exercise period, of such awards. All stock options granted have an exercise price equal to or greater than the fair value of the Companys common stock on the date the option is granted. All restricted stock units
(RSUs) are granted with an exercise price of zero. Both stock options and RSUs granted generally have contractual terms of ten years and vest over two, three, or four years, depending upon the type of grant. Options granted to employees
and directors are valued using the Black-Scholes model, and the resulting expense is recognized using the accelerated method over the service period for the entire award.

Non-Employee GrantsThe Company records physician stock-based compensation expense in connection with any equity-based grants to the Companys affiliated radiologists in accordance
with the Compensation-Stock CompensationTopic of the FASB Accounting Standards Codification (ASC Topic 718) and the EquityTopic of the FASB Accounting Standards Codification (ASC Topic 505).

Because the Companys affiliated radiologists are independent contractors, the Company calculates the fair value of the stock-based
compensation expense in each period. The amount of physician stock-based compensation expense the Company records in a given period depends primarily on the number of shares subject to equity-based grants held by the Companys affiliated
radiologists, the number of hours worked, and the value of the Companys common stock at the end of the period. If the price of the Companys common stock increases over a given period, this accounting treatment results in compensation
expense that exceeds the expense the Company would have recorded if these individuals were employees. Stock-based compensation to the Companys affiliated radiologists is included in professional services expense.

Stock-Based Awards SummaryA summary of the Companys stock-based award activity for employees and non-employees
under the 2004 and 2006 plans is as follows:

Intrinsic value represents the amount by which the fair market value of the underlying stock exceeds the exercise price of the options
and RSUs. Fair market value is the Companys closing stock price as of September 30, 2010, which was $6.38.

Recognition of Compensation ExpenseDuring the three months ended September 30, 2010 and 2009, the Company
recognized stock compensation of $1.1 million and $1.2 million, respectively, and $2.3 million and $3.8 million during the nine months ended September 30, 2010 and 2009, respectively. As of September 30, 2010, the total remaining
unrecognized compensation cost related to unvested stock-based employee/director arrangements, net of an estimated forfeiture rate of 8.9%, was $3.0 million and is expected to be recognized over a weighted average period of 1.35 years.

The Company measures the compensation cost associated with stock-based payments by estimating the fair value of stock options as of the
grant date using the Black-Scholes option pricing model. The Company believes this valuation technique and the approach utilized to develop the underlying assumptions are appropriate in calculating the fair values of the stock options granted.
Estimates of fair value are not intended to predict actual future events or the value ultimately realized by the employees who receive equity awards.

The assumptions used to estimate the fair value of the stock-based arrangements were as follows:

Expected volatility
is estimated by looking at the historical volatility of the Companys stock price and considering whether or not the Companys future stock prices are expected to be materially different than the past. The risk-free interest rate is based
on the U.S.

8. INCOME TAXES

The effective tax rates on income or loss from
continuing operations for the three months ended September 30, 2010 and 2009 were 30.9% and 35.8%, respectively. The difference in effective rates was primarily attributable to increased state tax expense which reduced the income tax
benefit in the three months ended September 30, 2010. The effective tax rates on income from continuing operations for the nine months ended September 30, 2010 and 2009 were 9.6% and 17.2%, respectively. The differences in
effective tax rates were primarily attributable to the Company recording a non-cash goodwill impairment charge in the quarter ended March 31, 2009, a portion of which was not deductible for tax purposes, and the tax impact relating to
the forfeiture of unvested stock grants in the nine months ended September 30, 2010.

Based on the Companys current
assessment of future taxable income, including available tax planning opportunities, the Company anticipates that it is more likely than not that it will generate sufficient taxable income to realize its recorded deferred tax assets, and therefore
the Company did not record a valuation allowance against its deferred tax assets as of September 30, 2010, except for a valuation allowance of $0.9 million (shown net of federal tax benefit) on a state net operating loss due to the limited
number of remaining years to carry the loss forward in that state. However, changes in the estimate of future taxable income and deterioration in the business and economic climate could significantly affect the determination of the necessity for a
valuation allowance against deferred tax assets in future periods.

9. DERIVATIVE FINANCIAL INSTRUMENTS

The Company recognizes all derivatives on the condensed consolidated balance sheet at fair value. The Company designates at inception
whether the derivative contract is considered hedging or non-hedging in accordance with the Derivatives and HedgingTopic of the FASB Accounting Standards Codification (ASC Topic 815).

In December 2008, the Company settled the two interest rate swap contracts entered into during 2007 resulting in a cash payment by the
Company of $5.3 million. The pre-tax net unrealized loss within accumulated other comprehensive income associated with the cancelled interest rate swap contracts of $5.3 million was amortized to interest expense over the original lives of the
contracts. Of this $5.3 million amount, $3.3 million was recognized in 2009 and $2.0 million was recognized during the nine months ended September 30, 2010. The cancelled swap contracts were replaced with five interest rate swap contracts with
a combined notional amount of $93.5 million in December 2008.

The interest rate
swap contracts were initiated to maintain compliance with debt requirements and to protect the Company against changes in the interest payments associated with its variable-rate long-term debt, and therefore were considered cash flow hedges. As a
result, as long as the swap contract was deemed highly effective, changes in the fair value of the swap contract were recorded as either an asset (a gain position) or a liability (a loss position) on the balance sheet, with the offset recorded in
accumulated other comprehensive income, a separate component of stockholders equity. As a condition to the consent the Company obtained from its lenders in connection with the June 2010 settlement with SPRPA the Company agreed to pay $26.0
million of its Term Loan on June 30, 2010 and an additional $10.0 million no later than June 30, 2011. As a result of the repayments, the Company determined that the three remaining effective interest rate swap contracts no longer met the
criteria for treatment as cash flow hedges under the guidance of ASC Topic 815 and related interpretations. Consequently, the Company prospectively discontinued cash flow hedge accounting for these interest rate swap contracts effective
January 1, 2010. Because cash flow hedge accounting was not applied to any interest rate swap contracts, changes in the fair value of these interest rate swap contracts from the beginning of 2010 through September 8, 2010 were recorded as
a component of interest expense in the Companys condensed consolidated statement of operations. For the three and nine months ended September 30, 2010, the interest expense associated with these ineffective hedges was $1.8 million and
$5.7 million, respectively.

In addition, the Company was also required to begin amortizing the related $0.9 million of
pre-tax net unrealized gain within accumulated other comprehensive income as of January 1, 2010 to interest expense. Of this $0.9 million amount, $0.5 million was recognized as a credit to interest expense during the nine months ended
September 30, 2010, leaving $0.4 million to be amortized in future periods. On September 8, 2010, the Company settled the five interest rate swap contracts resulting in a cash payment by the Company of $4.6 million. Because of this
settlement, there was no related liability or asset on the Companys balance sheet as of September 30, 2010. As of December 31, 2009, the fair value of the interest rate swap contracts on the Companys balance sheets was an asset
(a gain position) of $1.1 million.

The following tables summarize the effect of the Companys interest rate swap

10. FAIR VALUE MEASUREMENTS

The Fair Value Measurements and DisclosuresTopic of the FASB Accounting Standards Codification (ASC Topic 820),
defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market
participants on the measurement date. ASC Topic 820 also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard
describes three levels of inputs that may be used to measure fair value:

Level 1Quoted prices in active markets
for identical assets or liabilities.

Level 2Observable inputs other than Level 1 prices such as quoted prices for
similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of
the assets or liabilities.

The Company uses quoted market prices for identical assets to measure the fair value of its
investments in money market funds and marketable securities and therefore considers all of the Companys money market funds and marketable securities as Level 1.

Prior to the
termination of its interest rate swap contracts in September 2010, the Company determined that its interest rate swaps were Level 2 in the fair value hierarchy discussed above. As discussed in Note 4Long-Term Debt, the
Companys interest rate swaps were based on a LIBOR rate. Fair value for the interest rate swaps was based on a model-derived valuation using the LIBOR rate, which is observable at commonly quoted intervals for the full term of the swap.

The fair values of the Companys money market funds using Level 1 inputs on a recurring basis as of September 30,
2010 and December 31, 2009 were $16.3 million and $18.9 million, respectively. The carrying value of the Companys note receivable of $12.4 million as of September 30, 2010 approximates its fair value. The fair value of the
Companys marketable securities using Level 1 inputs on a recurring basis as of December 31, 2009 was $6.0 million. The fair value of the Companys interest rate swap contracts using Level 2 inputs on a recurring basis as of
December 31, 2009 was a gain position (an asset) of $1.1 million.

11. RESTRUCTURING CHARGE

During the three months ended September 30, 2010, the Company recorded a pre-tax charge of $0.4 million in accordance
with the Exit or Disposal Cost ObligationsTopic of the FASB Accounting Standards Codification (ASC Topic 420). The charge primarily pertained to a vacated lease for a portion of the Companys office facility in Coeur dAlene,
Idaho.

During the three months ended June 30, 2010, the Company recorded a pre-tax charge of $1.1 million in accordance
with ASC Topic 420. The charge was comprised of (i) $0.6 million pertaining to vacated leased facilities located in San Francisco, California, Austin, Texas and a portion of the Companys office facility in Coeur dAlene, Idaho,
(ii) $0.3 million in employee severance costs and (iii) fixed asset impairment charges of $0.2 million for certain property, plant and equipment within the vacated leased facilities that no longer have value to the Company.

The accruals related to vacated facilities is calculated net of any estimated sublease income which is estimated based on current market
quotes for similar properties and the anticipated timing of any potential subleases. If the Company is unable to sublet the vacated properties on a timely basis or is forced to sublet them at lower rates due to changes in market conditions, the
Company will adjust the accruals accordingly. The charges were recognized in sales, general and administrative expense. A reconciliation of the accruals on the Companys balance sheet for all abandoned leases as of September 30, 2010 is as
follows (dollars in thousands):



|                                        |  |        |       |

12. DISCONTINUED OPERATIONS

The Company determined that the business services operations of MPS and the teleradiology operations of ERS became discontinued operations during the quarter ended June 30, 3010. The Company
therefore recorded the operations of MPS and ERS as discontinued operations in accordance with the Presentation of Financial StatementsTopic of the FASB Accounting Standards Codification (ASC Topic 205). As a result, the Company has
segregated the assets and liabilities and operating results of MPS and ERS from continuing operations on the Companys balance sheet and in the consolidated statements of operations for all periods prior to the settlement transaction.

The following table summarizes results of discontinued operations for the periods indicated (dollars in thousands):

13. PROPOSED MERGER

On September 26, 2010, the Company entered into an Agreement and Plan of Merger (the Merger Agreement) by and among the Company, vRad, and Eagle Merge Sub Corporation, a wholly owned
subsidiary of vRad (Merger Sub). Pursuant to the terms of the Merger Agreement, Merger Sub would be merged with and into the Company, and as a result the Company would continue as the surviving corporation and a wholly-owned subsidiary
of vRad.

Pursuant to the Merger Agreement, if the transaction is consummated, each issued and outstanding share of the
Companys common stock will be canceled and extinguished and automatically converted into the right to receive $6.50 in cash. Options to purchase the Companys common stock that are in the money and restricted stock units, whether vested
or unvested, will be converted into a right to receive cash consideration as described in the Merger Agreement. The proposed transaction is subject to customary closing conditions, including, among others, adoption of the merger agreement by the
Companys stockholders, regulatory approvals, absence of any law or order prohibiting the transaction, accuracy of certain representations and warranties and material compliance with covenants, and the absence of any material adverse effect
with respect to the Company. Through September 30, 2010, the Company has incurred merger and acquisition related expenses of $0.5 million, which consist primarily of legal and accounting costs.

Overview

We are leading the transformation of the practice of radiology by providing high-quality, cost-effective solutions to radiology groups and hospitals throughout the United States. Our team of independent
contractor, American Board of Radiology-certified, state-licensed and hospital-privileged physicians, provides professional services (interpretations, exams, scans or reads) 24 hours per day, seven
days a week, for approximately 25% of all U.S. hospitals. The reads that we provide continue to consist primarily of off-hours preliminary reads, but increasingly include final and sub-specialty interpretations. For more information, visit our
website at www.nighthawkrad.net. The information contained on, or accessible through, our website is not incorporated in this filing.

Recent Developments

Proposed Merger Agreement

On September 26, 2010, and as described in our Current Report on Form 8-K filed with the SEC on September 27, 2010, we entered
into an Agreement and Plan of Merger, or the Merger Agreement, by and among us, vRad, and Eagle Merge Sub Corporation, or Merger Sub, a wholly-owned subsidiary of vRad. Pursuant to the terms of the Merger Agreement, Merger Sub would be merged with
and into us, and as a result we would continue as the surviving corporation and a wholly-owned subsidiary of vRad. vRad and Merger Sub are affiliates of Providence Equity Partners L.L.C.

Pursuant to the Merger Agreement, if the transaction is consummated, each issued and outstanding share of our common stock will be
canceled and extinguished and automatically converted into the right to receive $6.50 in cash. Options to purchase our common stock that are in the money and restricted stock units, whether vested or unvested, will be converted into a right to
receive cash consideration as described in the Merger Agreement. The proposed transaction is subject to customary closing conditions, including, among others, adoption of the merger agreement by our stockholders, regulatory approvals, absence of any
law or order prohibiting the transaction, accuracy of certain representations and warranties and material compliance with covenants, and the absence of any material adverse effect with respect to us.

Settlement of Interest Rate Swap Contracts

In September 2010, we settled our five existing interest rate swap contracts. The interest rate swap contracts, while in place, fixed interest expense on our variable-rate debt at approximately 4.95%. In
future periods our interest rate expense will fluctuate with changes in interest rates. We paid $4.6 million to the contract counterparty as part of the settlement.

Cost Reduction Actions and Related Restructuring Charges

As part of a plan
to reduce our operating costs, we closed an additional portion of our office facility in Coeur dAlene, Idaho. As a result of this closure and a related reduction in force of approximately 23 employees, we incurred restructuring costs of $0.4
million during the quarter, substantially all of which was for lease abandonment charges.

Trends in our
Business and Results of Operations

Evolving Marketplace.

The market for our services continues to evolve rapidly, as we continue to see significant competition in the market for our services,
resulting in continued price declines and increased customer attrition. More recently, we are also experiencing slower growth in volumes from our existing customers. We believe this trend has resulted primarily from lower utilization of healthcare
services in general resulting in fewer imaging procedures being performed. We also believe this trend is related to some of our customers reading later into the evening and, thus, utilizing our services for fewer hours. In response, we have focused
our efforts on setting and maintaining high quality service levels, demonstrating the value of our services to our customers and their patients, and when appropriate, lowering our prices to retain customers or gain new customers.

Service Revenue.

We generate revenue primarily from off-hours preliminary exams and to a lesser extent from final and subspecialty interpretations. As described above, over the course of the last several quarters, we
have continued to experience a maturing and highly competitive marketplace and a slowing in organic growth, resulting in slow or no growth in scan volumes. In addition, we have also seen the average price for our services decline significantly and
experienced customer losses. All of these factors have caused our revenues and margins to decline in recent periods. We expect these challenges to continue in the foreseeable future. In response to such trends, our strategy is to sell new
services, principally final interpretations, to our existing customers and to new customers by communicating their value and demonstrating the advantages we offer over our competitors. For example, in the last 12 months, our finals business has
increased from approximately 15% of our revenue to approximately 17% for the quarter ended September 30, 2010. We anticipate that our finals business will continue to become a larger percentage of our overall business in future periods. In
addition, following the announcement of the proposed merger, some customers and prospects have deferred purchase decisions for our services, negatively impacting our future growth in scan volume and revenue.

Professional Service Expenses.

Professional service expenses consist primarily of the fees we pay to our affiliated radiologists, any physician stock-based compensation, the premiums for medical liability insurance, and any medical
liability claims loss expenses. Since inception, our professional service fees have increased in absolute dollars each year, primarily due to the increased number of reads performed as our volumes have increased and the addition of new affiliated
radiologists to perform the increased workload. We expect that our professional service fees will continue to fluctuate in absolute dollars as volumes and modality mix vary. We also expect our professional services expenses to increase as a
percentage of revenue due to the shift in our business towards more final reads and due to the price declines we are experiencing.

Our medical liability expense continues to fluctuate in absolute dollars each year, primarily due to changes in volumes and claims experience. We expect our medical liability premiums and our reserves for
incurred but not reported or IBNR, medical liability claims to continue to fluctuate as our claims experience and volumes change over time.

We record physician stock-based compensation expense in connection with any equity-based grants to our affiliated radiologists in accordance with the Compensation-Stock CompensationTopic of the
FASB Accounting Standards Codification (ASC Topic 718) and the EquityTopic of the FASB Accounting Standards Codification (ASC Topic 505), and present this expense in our consolidated statements of operations as part of our professional
services expense. The amount of physician stock-based compensation expense we record in a given period depends primarily on the number of shares subject to equity-based grants held by our affiliated radiologists, the number of hours worked, and the
change in the value of our common stock in that period. Our expense in future periods for physician stock-based compensation will be driven primarily by changes in our stock price, new equity-based grants we make to our affiliated radiologists, and
the rate at which those equity-based grants are earned over such periods. We anticipate increased physician stock-based compensation expense this year and in 2011 resulting primarily from equity grants of our common stock issued during the quarter
ended March 31, 2010 to our affiliated physicians in connection with the adoption of a new form of physician contract in December 2009.

Sales, General and Administrative Expenses.

Our sales, general and
administrative expenses consist primarily of salaries and related expenses for our employees, employee stock-based compensation, information technology and telecommunications expenses, costs associated with licensing and privileging our affiliated
radiologists, facilities and office-related expenses, sales and marketing expenses and other general and administrative expenses. Our sales, general and administrative expenses have increased in absolute dollars since inception primarily as a result
of increased payroll expenses in connection with higher headcount in support of the growth in our business. Recently we have undertaken cost reduction initiatives which included headcount reductions and facilities closures. We are continuing to
evaluate opportunities to reduce costs and drive efficiencies throughout our organization by optimizing and automating our workflow processes.

Interest Expense.

Interest on our outstanding debt is at a variable rate. Starting in 2007, we hedged the risk associated with fluctuations
in interest rates by entering into interest rate swap contracts. In December 2008, we settled our original interest rate swap contracts and entered into five new interest rate swap contracts that had a term roughly equal to the remaining term on our
loan. In September 2010 we terminated these interest rate swap contracts. As a result, we will no longer experience variability in interest rate expense due to mark-to-market adjustments on these contracts; however, we could experience volatility in
our interest expense as our payments are now based on a floating rate. Finally, interest expense is expected to be lower in future periods due to lower interest rates, and recent and future principal repayments (subject to the impact of any future
changes in market interest rates).

Income Tax Expense.

Income tax expense consists of U.S federal, state, and foreign jurisdiction income taxes. We expect our income tax expense to
fluctuate due to changes to the Internal Revenue Code and the apportionment of our business geographically with regards to state taxes. Our income tax expense may also increase or fluctuate in future periods if our actual stock compensation
deductions are less than our previously recognized tax benefit in accordance with the Compensation-Stock CompensationTopic of the FASB Accounting Standards Codification (ASC Topic 718) or if, in the future, we determine that all or a portion
of our deferred taxes are not realizable.

Critical Accounting Estimates and Recently Issued Accounting Standards

The preparation of financial statements in accordance with GAAP requires our management to select and apply accounting
policies that best provide the framework to report the results of operations and financial position. The selection and application of those policies requires management to make difficult, subjective and/or complex judgments concerning reported
amounts of revenue and expenses during the reporting period and the reported amounts of assets and liabilities at the date of the financial statements. As a result, there exists the likelihood that materially different amounts would be reported
under different conditions or using different assumptions.

As of September 30, 2010, there have been no significant
changes with regard to the critical accounting policies disclosed in our Annual Report on Form 10-K for the year ended December 31, 2009. The policies disclosed included contingencies, accounting for long-lived assets, stock-based compensation,
income taxes and derivative accounting.

See Note 1Summary of Significant Accounting PoliciesRecently Issued
Accounting Standards to the condensed consolidated financial statements included in Item 1 of this report for additional information regarding recently adopted and new accounting pronouncements.

Results of Operations

The discussion of our results of continuing operations below relates exclusively to our preliminary, final and sub-specialty interpretations business. It excludes the results related to the business
services operations of MPS and the teleradiology operations of ERS prior to the settlement with SPRPA on June 30, 2010. The results of operations for the business services operations of MPS and teleradiology operations of ERS have been
segregated from continuing operations and reflected as discontinued operations for all periods presented. See Note 12Discontinued Operations to the accompanying consolidated statements. Our results of continuing operations were as
follows:

The decrease in service
revenue for the three months ended September 30, 2010 million compared to prior year period was primarily driven by declines in our average price. Preliminary read revenue declined $4.5 million while final read revenue was relatively flat
from the prior year period.

The preliminary read revenue decrease was driven by a 9% decline in our average price from the
same period in 2009. Preliminary read volume also declined by 6% from the same period in 2009, the result of same site volume growth of 3% and new customer volumes of 5%, offset by a 13% decrease in volumes from the cumulative impact of customers
lost over the past 12 months.

The final read revenue was relatively flat compared to the same period a year ago. An 18%
increase in finals volumes due to new customers was offset by a 15% decline in the average price compared to the same period a year ago. Final read volume growth consisted of new customer growth of 44% offset by same site volume decline of 11% and a
15% decrease in volume from the impact of customers lost over the past 12 months. The decline in final read pricing was predominately driven by a mix shift towards lower-priced plain film reads and competitive pressures in the marketplace.

The decrease in professional services expense for three months ended September 30, 2010
compared to the prior year period was primarily attributable to approximately 3% lower volumes and lower average costs resulting from operational initiatives undertaken to improve physician scheduling. The increase in professional services expense
as a percentage of revenue resulted from the declines in our average price per scan from the year-ago quarter.

The decrease in sales, general and administrative expense for the three months ended
September 30, 2010 was primarily attributable to cost savings initiatives undertaken in 2010 offset by $0.4 million in restructuring charges and severance and $0.5 million in legal fees we incurred in the third quarter in connection with the
proposed merger with vRad and to legal fees related to the matters described in Part IIItem 1Legal Proceedings.

The increase in interest expense for the three months ended September 30, 2010 compared to
the prior year period was primarily attributable to the discontinuation of hedge accounting for all five of our interest rate swap contracts effective January 1, 2010 as compared to one ineffective hedge as of September 30, 2009. As a
result, the quarter-to-date change in the fair value of the ineffective hedges of $1.8 million was recorded to interest expense, compared to $0.2 million for the same quarter last year.

The decrease in income tax expense for the three months ended September 30, 2010 compared to
the prior year period was primarily due to the fact that during the three months ended September 30, 2009 there was income tax expense on operating income and during the three months ended September 30, 2010 there was income tax
benefit on an operating loss. In addition, the income tax benefit for the three months ended September 30, 2010 was reduced by the tax impact relating to the forfeiture of unvested stock grants. The difference in effective tax rates was
primarily attributable to expected non-utilization of certain state tax net operating loss carry-forwards, which reduced the income tax benefit in the three months ended September 30, 2010.

The decrease in service
revenue for the nine months ended September 30, 2010 compared to the prior year period was driven primarily by a $10.9 million decline in preliminary read revenue, partially offset by an increase of $1.1 million in final read revenue. The
preliminary read revenue decrease was primarily driven by a 9% decline in our average price from the same period in 2009. Preliminary read volumes declined 3% from the same period in 2009, consisting of same site volume growth of 2% and new customer
volume growth of 5%, offset by an 11% decrease in volume from the cumulative impact of customers lost over the past 12 months.

The final read revenue increase was driven by a 32% increase in volume partially offset by a 19% decline in the average price compared to
the same period a year ago. Final read volume growth consisted of new customer growth of 58% offset by 9% declines in same site volume and a 17% decrease from the impact of customers lost over the past 12 months. The 19% decline in final read
pricing was predominately driven by a mix shift towards lower priced plain film reads and competitive pressures in the marketplace.

The decrease in professional services expense for the nine months ended September 30, 2010
compared to the prior year period was primarily attributable to a reduction to reserves for our IBNR medical liability claims of $0.9 million resulting from updates to our historical claims data and the reversal of $0.4 million reserve relating to
Australian-based physicians workers compensation liabilities no longer deemed probable. Removing the effects of these two items, costs were relatively flat year over year and consistent with the relatively flat volumes. The increase in

The increase in sales, general and administrative expense for the nine months ended
September 30, 2010 compared to the prior year period was primarily attributable to restructuring expense of $1.5 million and severance charges of $0.4 million during the nine months ended September 30, 2010. We also incurred approximately
$0.5 million in legal and accounting costs associated with the proposed merger with vRad. In addition, we saw higher legal costs related to the matters described in Part IIItem 1Legal Proceedings. These increases were
partially offset by lower stock compensation expense.

Goodwill Impairment

We recorded a $68.7 million goodwill impairment charge during the three months ended March 31, 2009 due to our determination that the
fair value of goodwill was less than the carrying value. The goodwill impairment charge was non-cash and did not affect our

operations, cash flow or cash position. Of the $68.7 million, $61.8 million was attributable to continuing operations and $6.9 million was associated with discontinued operations.

The increase in interest expense for the nine months ended September 30, 2010 compared to the
prior year period was primarily attributable to the discontinuation of hedge accounting for all our interest rate swap contracts effective January 1, 2010. As a result, the year-to-date change in the fair value of the ineffective hedges of $5.7
million was recorded to interest expense, partially offset by lower interest expense due to lower outstanding debt.

The change in our income tax expense was due primarily to a smaller loss in the current period
than in the prior period. We recorded a non-cash goodwill impairment charge in the three months ended March 31, 2009, a portion of which is not deductible for tax purposes, resulting in an effective tax rate different than the statutory rate.

The differences in effective tax rates were primarily attributable to our recording a non-cash goodwill impairment
charge in the three months ended March 31, 2009, a portion of which was not deductible for tax purposes, and the tax rate impact relating to the forfeiture of unvested stock grants in the nine months ended September 30, 2010.

For the nine months end
September 30, 2010, the discontinued operations generated a net loss of $18.4 million on $10.2 million in revenue, as compared to a net loss of $2.9 million for the nine months ended September 30, 2009 on $16.4 million in revenue. The
net loss for the nine months ended September 30, 2010 included $27.3 million ($16.9 million after-tax) in intangible asset impairment compared to $6.9 million ($4.3 million after-tax) in goodwill impairment for the nine months ended
September 30, 2009.

Our intangible assets include those acquired as part of our July 2007 acquisition of MPS and ERS from
SPRPA and the related agreements entered into between us and SPRPA. As a result of the settlement negotiations during the three months ended March 31, 2010 described in Note 3Intangible Assets Subject to Amortization, we
determined that an impairment indicator was present related to the professional services and non-compete agreements we entered into with and trademarks acquired from, SPRPA. Specifically, based on the anticipated settlement agreement, we concluded
that $27.3 million of the $49.6 million carrying value of these intangible assets was impaired. As a result, we recorded a non-cash intangible impairment charge of $27.3 million in the three months ended March 31, 2010.

Non-GAAP Financial
Performance Measures

We present non-GAAP financial measures because we believe that they are a useful indicator of our
performance and ongoing operations, provide consistency and comparability with our past financial performance and facilitate investor comparisons of our operating performance with our peer companies. However, it is important to note that the
presentation of adjusted earnings per diluted share is not a measure of financial performance under GAAP and should not be considered a substitute for or superior to GAAP. The non-GAAP financial measures we report are as follows:

Adjusted net income from continuing operations We define adjusted net income from continuing
operations as net income from continuing operations excluding the tax effected impact of (i) the non-cash expense related to our stock-based compensation, (ii) the non-cash expense associated with the amortization of intangibles associated
with acquisitions, (iii) the non-cash expenses (or credits) for adjustments to our IBNR reserve (incurred but not reported medical liability reserves), (iv) non-cash interest expense, (v) restructuring costs, (vi) the non-cash
charges for goodwill or intangible asset impairments, (vii) non-cash adjustments for deferred tax balances, (viii) merger costs and (ix) other expenses accounted for from time to time. These other expenses may occur in future periods,
but the amounts recognized can vary from period to period and do not directly relate to our ongoing operations.

Adjusted net income from discontinued operations  We define adjusted net income from discontinued operations as net income
(loss) from discontinued operations excluding the tax effected impact of (i) the non-cash expense associated with the amortization of intangibles associated with acquisitions, (ii) non-cash interest expense, (iii) the non-cash charges
for goodwill or intangible asset impairments, and (iv) non-cash adjustments for deferred tax balances.

Adjusted
diluted earnings per share  We define adjusted diluted earnings per share in the same manner as each of the non-GAAP measures described above.

During the three months ended September 30, 2010, our adjusted net income from continuing operations
decreased $1.4 million compared to the year ago period. During the nine months ended September 30, 2010, our adjusted net income from continuing operations decreased $6.9 million year over year. The decline in both periods was primarily due to
the effects of lower average prices and lost customers, partially offset by cost reduction initiatives.

Operating Activities

We fund our operations primarily from cash flows generated by our operating activities and, historically, from the incurrence of debt. Net cash provided by operating activities for the nine months ended
September 30, 2010 and 2009 was $16.3 million and $21.5 million, respectively, a decrease of $5.2 million. The decrease in cash from operating activities primarily resulted from the impact of service price declines.

Investing Activities

Net cash flows provided by investing activities were $13.4 million for the nine months ended September 30, 2010, compared with $10.4 million used in investing activities for the nine months ended
September 30, 2009. The increase in net cash from investing activities compared to the same period a year ago primarily resulted from $9.9 million received as part of the SPRPA settlement and $6.0 million in proceeds from maturities of
marketable securities in the first nine months of 2010, compared to $11.0 million in purchases of marketable securities during the first nine months of 2009.

Financing Activities

Net cash used in financing activities was $31.1
million for the nine months ended September 30, 2010, compared with $33.4 million for the nine months ended September 30, 2009. The decrease in net cash used in financing activities compared to the same period a year ago primarily reflects
the principal payment of $26.0 million on our long-term debt as part of the agreement with our lenders following the closing of the settlement with SPRPA and the $4.6 million used to settle our interest rate swap contracts, compared to a $20.3
million purchase of shares of our common stock and $12.7 million in principal payments on our long term debt in the first nine months of 2009.

Financial Condition and Liquidity

We expect our short and long-term
liquidity needs to consist primarily of working capital, capital expenditures, including information technology and any future acquisitions. We will also have liquidity needs if we elect or are required to make principal payments under our
credit agreement. We intend to fund future liquidity needs from current capital resources and cash generated from operations. We believe our capital resources will be sufficient to meet our anticipated cash needs for at least the next 12 months.

Our credit agreement contains customary affirmative, negative and financial covenants, including, among other requirements,
negative covenants that restrict our ability to create liens, enter into mergers and acquisitions, pay dividends, repurchase stock, incur indebtedness, make investments and make capital expenditures, and financial covenants that limit the maximum
leverage we can maintain at any one time. Our term loan is subject to mandatory repayment under certain circumstances, including in connection with our receipt of proceeds from certain issuances of equity or debt, sales of assets and casualty
events. In addition, our credit agreement requires a principal payment in the amount equal to 50% of our Excess Cash Flow (as defined in our credit agreement) if the Total Leverage Ratio (as defined in our credit agreement) is at or above 2.5 at
year end. Furthermore, if our Total Leverage Ratio exceeds 4.0 on any trailing four quarter basis, our obligation to repay all borrowings could be accelerated. As of September 30, 2010, our Total Leverage Ratio was 3.54. In connection with
the settlement with SPRPA, we were required to obtain the consent of the lenders of the term loan and agreed to pay $26.0 million on the day of the settlement and make an additional payment of $10.0 million on or prior to June 30, 2011.
Pursuant to such consent, should we be required to make an Excess Cash Flow payment with respect to fiscal years 2010 and 2011, such payment will be reduced by an amount equal to these repayments. As of September 30, 2010 we were in compliance
with all covenants contained in our credit agreement and expect to remain in compliance with these covenants for at least the next 12 months.

Our financial results have been impacted as a result of the settlement with SPRPA. In the first nine months of 2010, we generated an aggregate of $10.2 million, or approximately 9% of our total revenue,
from our original agreements with SPRPA. As a result of the settlement, beginning July 1, 2010, we no longer derive revenue from such agreement or related profits that we have historically generated from SPRPA. As a result, our Total Leverage
Ratio under our credit agreement could exceed 2.5 for the year, which in turn would trigger a mandatory principal repayment by us equal to 50% of our Excess Cash Flow for such year, or 4.0, which could result in the acceleration of our obligation to
repay all of our borrowings under our credit agreement. If we fail to meet either of our Total

in the future and we are required to make a mandatory repayment of a portion of the principal of our term loan, or if our obligations under our term loan are accelerated as a result of our default, our financial condition would be materially
adversely impacted.

transaction with SPRPA, we will make an additional $10.0 million principal payment to the lenders on or before June 30, 2011. We currently expect to make this $10.0 million payment in the fourth quarter of 2010.

Leverage Ratio Calculation

Pursuant to the terms of our credit agreement, we are required to calculate our Total Leverage Ratio on a pro forma basis, meaning that we must calculate our Total Leverage Ratio assuming the SPRPA
settlement transaction took place at the beginning of the trailing four quarter measurement period. As a result, even with the $26 million principal payment described above, we expect our Total Leverage Ratio in future periods to increase. The
calculation of our Total Leverage Ratio as of September 30, 2010 is provided below (dollars in thousands, except ratio):

Finally, we may elect from time to time to make additional principal payments on our debt in order to
enhance our capital structure as we have in prior years. We anticipate funding any such elective or required principal payments out of our available cash and cash equivalents. However, if our estimates of revenues, working capital and/or capital
expenditure requests change or prove inaccurate, we may need to raise additional funds to satisfy any required principal payment. There can be no assurance that any such funds will be available at the time or times needed or available on terms
acceptable to us. See Part IIItem 1ARisk FactorsWe may need additional capital, which may not be available to us.

|ITEM 3. | Quantitative and Qualitative Disclosures about Market Risk
|------- | ----------------------------------------------------------

Foreign Currency Exchange Risk

During the periods covered by this
quarterly report, substantially all of our customers are in the United States and thus revenue is denominated in U.S. dollars. Although some of our affiliated radiologists work from our centralized reading facilities in Australia and Switzerland,
the professional service fees we pay to our affiliated radiologists are denominated primarily in U.S. dollars. As a result, only our support personnel and facility costs in those countries present foreign currency exchange risks. Because we are not
currently subject to material foreign currency exchange risk, we have not, to date, entered into any foreign exchange hedging contracts. If a weakening U.S. dollar requires us to increase the amounts we pay to our affiliated radiologists in the
future in order to maintain a constant level of compensation, our results of operations and cash flows could be affected. Currently, any foreign exchange risks are related to the foreign currency exchange rates between the U.S. dollar and the
Australian dollar and between the U.S. dollar and the Swiss franc.

Interest Rate Sensitivity

As of September 30, 2010, we had cash and cash equivalents totaling $24.9 million. The majority of these amounts is invested in
interest-bearing money market accounts and is held for working capital purposes. We had no marketable securities outstanding as of September 30, 2010.

As of September 30, 2010, we had $51.7 million in variable rate debt. The interest rate on this debt is based on the three-month LIBOR rate. As a result of the September 2010 termination of our
interest rate swap contracts entered into during the fourth quarter of 2008, this outstanding debt is now subject to market interest rate fluctuations through its maturity in July 2014.

For more information on our interest rate hedging activities, see Note 9Derivative Financial Instruments, included in
Part I Item 1 of this report.



|ITEM 4. | Controls and Procedures
|------- | -----------------------

Evaluation of Disclosure Controls and Procedures

As of September 30, 2010, we carried out an evaluation, under the supervision and with the participation of 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 defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934). Based upon that evaluation, the Chief Executive Officer and Chief
Financial Officer concluded that as of September 30, 2010, our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934) were effective.

Changes in Internal Control over Financial Reporting

During the three months ended September 30, 2010, there were no changes in our internal control over financial reporting that have
materially affected or are reasonably likely to materially affect such internal control over financial reporting.

Securities Class Action and Related Derivative ClaimIn our Annual Report on Form 10-K, we reported that, on

##### Table of Contents

District of Idaho. The case is captioned City of Marysville General Employees Retirement System v. NightHawk Radiology Holdings, Inc., et al., Case No. CIV 09-659-N-CWD. On
July 13, 2010, plaintiffs filed an amended complaint under the new caption In re Nighthawk Radiology Holdings, Inc. Securities Litigation, Master File No. 09-cv-00659 (EJL/CWD). The complaint purports to be brought on behalf of a
class of persons who purchased or otherwise acquired our stock during the period May 2, 2007 to May 7, 2008, and asserts claims under Section 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5
promulgated thereunder. Plaintiffs contend that the Company and the individual defendants violated the federal securities laws by issuing false and misleading statements concerning the Companys operations, business, and prospects during the
purported class period, and thereby artificially increased the price of the Companys stock. Plaintiffs seek unspecified compensatory damages, interest, and attorneys fees and costs. On April 29, 2010, the court issued an order
appointing Plymouth County Contributory Retirement System (Plymouth) as lead plaintiff. On May 13, 2010, competing plaintiff Miramar Firefighters Pension Fund (Miramar) filed an objection to the courts
appointment of Plymouth as lead plaintiff and requested that the court instead appoint Miramar as lead plaintiff. The court has yet to rule on that motion. Pending the courts ruling on this objection, all deadlines have been taken off
calendar, including defendants deadline to respond to the complaint. Management intends to vigorously defend against these claims.

In connection with the securities class action described above, on September 2, 2010, a shareholder derivative lawsuit was also filed in the U.S. District Court for the District of Idaho, purportedly
on behalf of and for the benefit of the Company, against certain of our current and former officers and directors. The case is related to the securities class action case and is captioned Israni v. Berger, et al., Case
No. 10-cv-00450-BLW. On September 8, 2010, a similar shareholder derivative lawsuit was filed in Kootenai County District Court. This lawsuit is captioned Jarrett v. Berger, et al. 10-7752. The Company is named as a nominal
defendant in both lawsuits. The derivative complaint is premised on the same basic allegations of fact as the securities class action and alleges, among other things, that certain of our current and former officers and directors breached their
fiduciary duties to the Company and were unjustly enriched in connection with the public disclosures that are the subject of the securities class action. Because these lawsuits are derivative in nature, they do not seek monetary damages from the
Company. We may, however, be required through the pendency of these lawsuits to advance the legal fees and costs of the defendant officers and directors.

Merger LitigationIn connection with the announcement of our merger agreement with Virtual Radiologic Corporation (vRad) (see Management Discussion &
AnalysisRecent Developments and Item 1A Risk FactorsThe proposed acquisition by vRad may adversely affect our results of operations and prospects and may not be consummated on the contemplated schedule or at all),
beginning on September 28, 2010, several putative class action lawsuits were filed purportedly on behalf of our stockholders in the Superior Court of Maricopa County, Arizona, docketed as Israni v. NightHawk Radiology Holdings, Inc., et
al., Case No. CV2010-025059, LaLone v. NightHawk Radiology Holdings, Inc., et al., Case No. CV2010-028112, La Torre v. NightHawk Radiology Holdings, Inc., et al., Case No. CV2010-028176, Watts v. Engert, et al., Case No.
CV2010-028127, Newman v. Engert, et al., Case No. CV2010-028262, and Yu v. Engert, et al., Case No. CV2010-028403. On October 8, 2010, a purported class action lawsuit on behalf of the Companys stockholders was filed in
Delaware Chancery Court, docketed as Scully v. NightHawk Radiology Holdings, Inc., et al., Case No. 5890-VCL. The complaints name the Company, each of the members of our board of directors, and vRad as defendants. The lawsuits allege,
among other things, that our board of directors breached fiduciary duties owed to our stockholders by failing to take steps to maximize stockholder value or to engage in a fair sale process when approving the proposed merger with vRad. The
complaints also allege that the Company and vRad aided and abetted the members of our board of directors in the alleged breach of their fiduciary duties. In the Delaware action, the plaintiff also alleges that the preliminary proxy contains certain
material omissions, rendering some statements therein misleading. The plaintiffs in these various actions seek relief that includes, among other things, an injunction prohibiting the consummation of the proposed merger, a court order declaring that
the board of directors breached their fiduciary duties in entering into the merger agreement, rescissionto the extent the merger terms have already been implemented, and the payment of plaintiffs attorneys fees and costs. We
believe the lawsuits to be without merit and intend to defend against them vigorously. There can be no assurance, however, with regard to the outcome of these lawsuits.

In addition to the proceedings described above, we are also involved in various legal proceedings arising in the ordinary course of our business activities. We maintain insurance policies with coverages
that we believe are appropriate in light of the risks attendant to our business, and believe that the resolution of the current claims will not have a material adverse impact on our consolidated results of operations, cash flows or our financial
position. However, depending on the amount of damages resulting from a current or future claim, an unfavorable resolution of a claim could materially affect our future results of operations, cash flows or financial position.

FINANCIAL STATEMENTS AND THE RELATED NOTES, BEFORE DECIDING TO PURCHASE ANY SHARES OF OUR COMMON STOCK.

The proposed acquisition by vRad may adversely affect our results of operations and prospects and may not be consummated on the contemplated schedule or at all.

On September 26, 2010, we entered into a merger agreement providing for the acquisition of our company by vRad for a purchase price
of $6.50 per share. The proposed transaction, whether or not consummated, may result in a diversion of managements attention from day-to-day operations, a loss of key personnel and a disruption of our operations. The proposed
transaction may also affect our relationships with customers and affiliated radiologists which, in turn, may adversely affect our results of operations and prospects. The merger agreement imposes customary restrictions on the conduct of our
business outside of the ordinary course prior to the closing of the transaction or the termination of the merger agreement, which may also adversely affect our ability to manage our operations effectively in light of changes in economic or market
conditions or to execute our business strategy and meet our financial goals. Additionally, we, our directors and vRad have been named in purported class actions relating to the proposed transaction as more fully described in Note
5Commitments and ContingenciesMerger Litigation included in Part I Item 1 of this report and under Part II, Item 1Legal Proceedings; these or any future lawsuits or proceedings may be time consuming and
expensive. A delay in the consummation of the proposed transaction could exacerbate the impact of the risks associated with the proposed transaction, if they were to occur.

The proposed transaction is subject to customary closing conditions, including, among others, adoption of the merger agreement by our
stockholders, regulatory approvals, absence of any law or order prohibiting the transaction, accuracy of certain representations and warranties and material compliance with covenants, absence of any material adverse effect with respect to our
company.

The merger agreement contains certain termination rights for both us and vRad and further provides that, upon
termination of the merger agreement under specified circumstances, we may be required to pay vRad a termination fee of up to $6.6 million.

We cannot predict whether or when the closing conditions for the proposed transaction set forth in the merger agreement will be satisfied or whether the proposed transaction will be completed. If the
closing conditions are not satisfied or waived pursuant to the merger agreement on the contemplated schedule, or if consummation of the transaction is delayed, enjoined or not completed for any other reason, the market price of our common stock may
decline. In addition, if the proposed transaction does not occur, we may nonetheless remain liable for significant transaction expenses.

The occurrence of any of these events individually or in combination could have a material adverse effect on our results of operations and prospects, as well as on our stock price.

We operate in a rapidly evolving market, which makes it difficult to evaluate our business and prospects.

Our industry is relatively new and is rapidly evolving. As a result, our current business and future prospects are difficult to evaluate.
You must consider our business and prospects in light of the risks and difficulties we encounter as an early leader in a rapidly evolving market. Some of these risks relate to our potential inability to:



| |  |  | effectively manage the reaction of customers, potential customers and affiliated radiologists to the announcement of the proposed acquisition by vRad;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | effectively manage our business and technology,
| | - |  | -----------------------------------------------



| |  |  | effectively manage our operating costs as the price for our services declines,
| | - |  | ------------------------------------------------------------------------------



| |  |  | continue to provide consistently high levels of service quality as we expand the scale of our business,
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | develop new services that complement our existing business,
| | - |  | -----------------------------------------------------------



| |  |  | acquire additional customers and maintain current customers in a highly competitive environment,
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | market our services to our customers due to regulatory rules governing reassignment of payments, which could affect our customers ability to
collect fees for services provided by our affiliated radiologists,
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | effectively manage the integration of companies that we may acquire in the future,
| | - |  | ----------------------------------------------------------------------------------



| |  |  | manage growth in personnel and operations,
| | - |  | ------------------------------------------



| |  |  | effectively manage our medical liability risk, and
| | - |  | --------------------------------------------------



| |  |  | recruit and retain radiologists and other key personnel.

We may not be able to
successfully address these and the other risks described in this report. Failure to adequately do so would harm our business and cause our operating results to suffer. Furthermore, our early operating history resulted in historical revenue growth
rates that we will likely not be able to repeat, and therefore will not be indicative of our future results of operations. As a result, the price of our common stock could decline.

The market in which we participate is competitive and we expect competition to increase in the future, which will make it more
difficult for us to sell our services and has resulted and may continue to result in pricing pressure, reduced revenue and reduced market share.

The market for professional radiology services and business process services is competitive and rapidly changing, barriers to entry are relatively low, and with the introduction of new technologies and
market entrants, we expect competition to continue to intensify in the future. In fact, in recent periods we have experienced an increase in competition from regional providers of services similar to ours. If we fail to compete effectively, our
operating results will be harmed. Some of our principal competitors, including our largest competitor, vRad, offer their services at a lower price, which has resulted and may continue to result in pricing pressure and lost customers. If we are
unable to maintain our current pricing or effectively revise the way we compensate our affiliated radiologists, our operating results would be negatively impacted. In addition, pricing pressures and increased competition would result in reduced
revenue and reduced profits.

In addition, if companies larger than us enter the market through internal expansion or
acquisition of one of our competitors, the change in the competitive landscape could adversely affect our ability to compete effectively. These competitors could have established customer relationships and greater financial, technical, sales,
marketing and other resources than we do, and may be able to respond more quickly to new or emerging technologies or devote greater resources to the development, promotion and sale of their services. This competition could harm our ability to sell
our services, which may lead to lower prices, reduced revenue and, ultimately, reduced market share.

We may be unable
to successfully expand our services beyond the off-hours emergency radiology market.

A key part of our strategy to
offset the moderation of growth in our provision of preliminary reads involves providing final reads and sub-specialty services; however, our efforts to provide these final reads and sub-specialty services, or any other services beyond our current
services offerings and radiology solutions, may not result in significant revenue growth for us. The markets for final and sub-specialty reads are more complex than the market for preliminary reads. If we are to be successful in these markets, we
will be required to develop, execute and maintain new sales and marketing efforts, as well as new information technology capabilities. Our ability to do so may be adversely affected by the announcement of our proposed acquisition by vRad. In
addition, our final and sub-specialty service offering requires our customers to navigate the billing and collecting rules related to the reads our affiliated physicians provideincluding the billing reassignment rules and the rules regarding
where to bill for such servicesrules that are often cumbersome and difficult for our customers. As a result, our efforts to expand our services into these new markets may divert management resources from existing operations and require us to
commit significant financial resources to an unproven business. If we are unable to effectively address the challenges that these new service offerings present, our business, financial condition and results of operations could be adversely affected.

If our customers perceive that we are offering services that are competitive to theirs, some of our customers may
terminate their agreements with us, which could adversely affect our business, financial condition and results of operation.

Historically, some radiology groups have been concerned that teleradiology companies may potentially become competitive with them for their business. Our core mission has always been to work with and to
support our radiology group customers and we are committed to acting consistently with our mission of supporting our radiology group customers and not competing with them. Despite this, as the largest teleradiology company in the industry, we are
particularly vulnerable to the potential that there could be speculation or misperception by some radiology groups that we may become competitive with their business, which may result in some customers choosing to discontinue doing business with us.
If this were to occur, our business, financial condition and results of operations could be adversely affected.

If our
arrangements with our affiliated radiologists or our customers are found to violate state laws prohibiting the corporate practice of medicine or fee splitting, our business, financial condition and our ability to operate in those states could be
adversely impacted.

The laws of many states, including states in which our customers are located, prohibit us from
exercising control over the medical judgments or decisions of physicians and from engaging in certain financial arrangements, such as splitting professional fees with physicians. These laws and their interpretations vary from state to state and are
enforced by state courts and regulatory authorities, each with broad discretion. We enter into agreements with our affiliated radiologists pursuant to which the radiologists render professional medical services using their independent judgment and
discretion with no influence by NightHawk. In addition, we enter into agreements with our customers to deliver professional radiology interpretation services in exchange for a service fee. We structure our relationships with our affiliated
radiologists and our customers in a manner that we believe is in compliance with prohibitions against the corporate practice of medicine and fee splitting. If any state regulatory or similar authority determines that we are engaged in the corporate
practice

of medicine or that the payment of service fees to us by our customers constitutes fee splitting, we could be subject to civil and criminal penalties and could be required to restructure or
terminate the applicable contractual arrangements. A determination that these arrangements violate state statutes, or our inability to successfully restructure our relationships with our affiliated radiologists to comply with these statutes, could
eliminate customers located in certain states from the market for our services, which would have a materially adverse effect on our business, financial condition and operations.

Our growth strategy depends on our ability to recruit and retain qualified radiologists. If we are unable to do so, our future
growth would be limited and our business and operating results would be harmed.

Our success is dependent upon our
continuing ability to recruit and retain qualified radiologists. An inability to recruit and retain radiologists would have a material adverse effect on our ability to service our customers and grow our revenues and would adversely affect our
results of operations. Our ability to recruit and retain radiologists may be adversely affected by the announcement of our proposed acquisition by vRad. We face competition for radiologists from other healthcare providers, including radiology
groups, teleradiology companies, research and academic institutions, government entities and other organizations. If we are unable to effectively recruit and retain qualified radiologists, our business, financial condition and results of operations
could be adversely affected.

If our affiliated radiologists are characterized as employees, we would be subject to
employment and withholding liabilities and may be subject to prohibitions against the corporate practice of medicine.

We structure our relationships with our affiliated radiologists in a manner that we believe results in an independent contractor
relationship, not an employee relationship. An independent contractor is generally distinguished from an employee by his or her degree of autonomy and independence in providing services. A high degree of autonomy and independence is generally
indicative of a contractor relationship, while a high degree of control is generally indicative of an employment relationship. Although we believe that our affiliated radiologists are properly characterized as independent contractors, tax or other
regulatory authorities may in the future challenge our characterization of these relationships. If the Internal Revenue Service , or IRS, (or other state, federal or foreign courts) were to determine that our affiliated radiologists are employees,
and not independent contractors, we would be required to withhold income taxes, to withhold and pay social security, Medicare and similar taxes and to pay unemployment and other related payroll taxes, would be liable for unpaid past taxes by our
affiliated radiologists and may be subject to penalties, all of which may materially harm our business and operating results. In connection with its audit of our tax filing for the 2006 tax year, the IRS reviewed our characterization of our
affiliated radiologists as independent contractors. As a result of that review, we received a letter on August 27, 2009 stating that no changes to the tax as reported would be made and no further examination of this matter will be made by the
IRS. However we cannot provide assurances that future audits would be consistent with this conclusion. If, in the future, the IRS were to reach a different conclusion, we believe we could successfully modify our relationships with our affiliated
radiologists to address such an outcome. However, if we were unable to successfully implement this new relationship with our affiliated radiologists, our business and results of operations could be adversely affected.

If our customers terminate their agreements with us or if our customers businesses materially decline, our financial
condition and operating results could be adversely affected.

Our revenue is derived primarily from fee-for-service
billings to our radiology group customers. Our agreements with our customers generally provide for one-year terms and automatically renew for successive one-year terms unless terminated by our customers or us upon 30 days prior notice. Our customers
may elect not to renew their contracts with us, they may seek to renegotiate the terms of their contracts or they may choose to reduce or eliminate our services. For example, due to a number of competitive factors, we saw an 11% decrease in read
volumes that resulted from the cumulative impact of customers that we lost over the last 12 months. In addition, in response to overall market conditions or concerns about pressures on their incomes, our radiology group customers may choose to
perform more of their own off-hours coverage for their hospital sites, resulting in lower volumes, or they may choose to terminate their agreements with us. If our customers decrease their utilization of our services, or if they terminate or cancel
their relationships with us, whether due to competitive factors or not, our business, financial condition and results of operations could be adversely affected. In addition, if our radiology group customers agreements with the hospitals that
they serve are terminated, or if our radiology group customers businesses begin to decline for other reasons (such as a material increase in the rate of uninsured patients or uncollectible accounts), our business, financial condition and
results of operations could be adversely affected.

If SPRPA does not satisfy its payment obligations with respect to
the $14 million aggregate principal amount promissory note it issued to us, our results of operations and cash flows would be adversely affected.

In June 2010, we resolved a dispute between us and SPRPA. In connection with such settlement, SPRPA issued to us an unsecured promissory note in the aggregate principal amount of $14 million, which is
payable to us over four years. If SPRPA defaults on its payment obligation under the note, our results of operations and cash flows would be adversely affected.

We have been
subject to medical liability claims and may become subject to additional claims or other harmful lawsuits, which could cause us to incur significant expenses and may require us to pay significant damages if not covered by insurance.

Our business entails the risk of medical liability claims against our affiliated radiologists and us. We or our
affiliated radiologists are subject to ongoing medical liability claims in the ordinary course of business. In addition, in some instances, these medical liability proceedings include allegations by plaintiffs that our business practices violate the
appropriate standard of care and that, as a result, a court should institute punitive damages against us. Although we maintain medical liability insurance for ourselves and our affiliated radiologists with coverage that we believe is appropriate in
light of the risks attendant to our business, successful medical liability claims could result in substantial damage awards which exceed the limits of our insurance coverage. In addition, medical liability insurance is expensive and insurance
premiums may increase significantly in the future, particularly as we continue to grow our final and sub-specialty services. As a result, adequate medical liability insurance may not be available to our affiliated radiologists or us in the future at
acceptable costs or at all.

Any claims made against us, including any claims that our business practices violate the standard
of care, that are not fully covered by insurance could be costly to defend against, result in substantial damage awards against us and divert the attention of our management and our affiliated radiologists from our operations, which could adversely
affect our operations and financial performance. In addition, any claims might adversely affect our business or reputation.

In addition to medical liability claims, we may also become subject to other litigation proceedings that, if not fully covered by
insurance, could be costly to defend against, result in substantial damage awards against us and divert the attention of our management.

We indemnify our radiology group customers and hospital customers against damages or liabilities that they may incur as a result of the actions of our affiliated radiologists or us. We also indemnify some
of our affiliated radiologists against medical liability claims. Our indemnification obligations are typically payable only to the extent that damages incurred are not covered by insurance.

We have also assumed and succeeded to substantially all of the obligations of the businesses that we have acquired. Medical liability
claims may be asserted against us for events that occurred prior to these acquisitions.

We are also dependent upon the
financial health of our medical liability insurance provider. Currently our medical malpractice provider is Chartis, Inc., an insurance subsidiary of American International Group (or AIG). We believe Chartis is adequately collateralized, however we
cannot guarantee its financial health. Should AIG or Chartis not have the funds available to cover claims made against us or our radiologists, our business, the financial condition and results of operations could be adversely affected.

If our security measures are breached and unauthorized access is obtained to patient or customer data, we may face liabilities and
our system may be perceived as not being secure, causing customers to curtail or stop using our services, which could lead to a decline in revenues.

We are required to implement administrative, physical and technological safeguards to ensure the security of the patient data that we create, process or store. These safeguards may fail to ensure the
security of patient or customer data, thereby subjecting us to liability, including civil monetary penalties and possible criminal penalties. If our security measures are breached, whether as a result of third party action, employee error,
malfeasance or otherwise, and, as a result, someone obtains unauthorized access to patient or customer data, our reputation will be damaged, our business may suffer and we could incur significant liability. Because techniques used to obtain
unauthorized access to systems change frequently and generally are not recognized until launched against a target, we may be unable to anticipate these techniques or to implement adequate preventive measures.

Enforcement of federal and state laws regarding privacy and security of patient information may adversely affect our business,
financial condition or operations.

The use and disclosure of certain healthcare information by healthcare providers
and their business associates have come under increasing public scrutiny. The federal standards under HIPAA establish rules concerning how individually identifiable health information may be used, disclosed and protected. Historically, state law has
governed privacy issues and HIPAA preserves these laws to the extent they are more protective of a patients privacy or provide the patient with more access to his or her health information. As a result of the implementation of the HIPAA
privacy and security regulations, many states are considering revisions to their existing privacy, security and breach notification laws and regulations that may or may not be more stringent or burdensome than the federal HIPAA privacy, security and
breach notification provisions. In addition, the recently enacted HITECH Act now empowers state attorneys general to enforce HIPAAs privacy and security provisions, including the new federal breach notification requirements. We must operate
our business in a manner that complies with all applicable laws, both federal and state, and which does not jeopardize the ability of our customers to comply with all applicable laws to which they are subject. We believe that our operations are
consistent with these legal standards. Nevertheless, these laws and regulations present risks for healthcare providers and their business associates that provide services to patients in multiple states. Because these laws and regulations are recent
and few have been interpreted by government regulators or courts, our interpretations and activities may be challenged. If a challenge to our activities is successful, it could have an



36

##### Table of Contents

adverse effect on our operations. In addition, even if our interpretations of HIPAA and other federal and state laws and regulations are correct, we could be held liable for unauthorized uses or
disclosures of patient information as a result of inadequate systems and controls to protect this information or due to the theft of information by unauthorized computer programmers who penetrate our network security. Lastly, new legislation to
broaden privacy and security rules has been introduced in Congress and in numerous states which may require that we change our operations.

Recently-enacted or future changes in healthcare regulation may constrain or require us to restructure our operations, which could negatively impact our business and operating results.

The healthcare industry is heavily regulated and has recently been the subject of significant legislative action. Our
ability to operate profitably will depend in part upon our ability (and that of our affiliated radiologists, our customers and their radiologists) to continue to operate effectively in the new health care environment. With the changes enacted by the
recently-passed Patient Protection and Affordable Care Act, we believe that there will be continued pressure on the overall imaging market and our customers by, among other things, a potential reduction in the growth in, or overall number of,
diagnostic imaging procedures performed, and a reduction in the payments to radiology groups and facilities for both the technical component and professional component of such procedures. Any reduction in demand for diagnostic imaging, as well as
reduced reimbursement to groups and facilities that utilize our services could in turn adversely affect our business.

Our
business could also be adversely affected by regulatory changes at the federal or state level that impose new requirements for licensing, new restrictions on reimbursement for medical services by government programs, new pretreatment certification
requirements for patients seeking radiology procedures, or new limitations on services that can be performed by us. In addition, federal, state and local legislative bodies have adopted and continue to consider medical cost containment legislation
and regulations that have restricted or may restrict reimbursement to entities providing services in the healthcare industry and referrals by physicians to entities in which the physicians have a direct or indirect financial interest or other
relationship. For example, Medicare has adopted a regulation that limits reimbursement for the technical component when multiple diagnostic tests are performed during a single session at medical facilities other than hospitals. Any of these or
future reimbursement regulations or policies could limit the number of diagnostic tests our customers order and could have a material adverse effect on our business.

Although we monitor legal and regulatory developments and modify our operations from time to time as the regulatory environment changes, we may not be able to adapt our operations to address every new
regulation, and such regulations may adversely affect our business. In addition, although we believe that we are operating in compliance with applicable federal and state laws, our business operations have not been scrutinized or assessed by
judicial or regulatory agencies. We cannot assure you that a review of our business by courts or regulatory authorities would not result in a determination that adversely affects our operations or that the healthcare regulatory environment will not
change in a way that will restrict our operations.

Our business could be materially affected if a HHS-OIG study results
in adverse modifications to Medicare payments for emergency room imaging.

In its Fiscal Year 2010 Work Plan, the
HHS-OIG lists as a work in progress its current inspection of the appropriateness of payments for hospital emergency department x-rays and interpretations. It is possible that, in the final report, the HHS-OIG could recommend changes to
CMS reimbursement rules regarding emergency imaging. If the HHS-OIG were to make such recommendations and, if such recommendations were adopted, such changes could adversely affect our operations.

Our operating results are subject to seasonal fluctuation, which makes our results difficult to predict and could cause our
performance to fall short of quarterly expectations.

Historically, we have experienced increased demand for and
revenues from our services during the second and third fiscal quarters of each year. We believe that these increases are a result of increased outdoor and transportation activities and a greater utilization of service hours during the summer months.
During the first and fourth quarters of each fiscal year, when weather conditions are colder for a large portion of the United States, we have historically experienced relatively lower revenues than those experienced during the second and third
quarters. We may or may not continue to experience this or other seasonality in the future. These seasonal factors may lead to unpredictable variations in our quarterly operating results and cause the trading price of our common stock to decline.
Additionally, our ability to schedule adequate radiologist coverage during the seasonal period of increased demand for our services may affect our ability to provide appropriate turnaround times in our services to clients.

Interruptions or
delays in our information systems or in network or related services provided by third-party suppliers could impair the delivery of our services and harm our business.

Our operations depend on the uninterrupted performance of our information systems, which are substantially dependent on systems we have developed internally since our inception as well as systems provided
by third parties over which we have little control. Failure to maintain reliable information systems, or disruptions in our information systems could cause disruptions and delays in our business operations which could have a material adverse effect
on our business, financial condition and results of operations.

We rely on broadband connections provided by third party
suppliers to route digital images from hospitals in the United States to our facilities in Australia, Switzerland and the United States. Any interruption in the functioning of our internal systems or in the availability of the network connections
between the hospitals and our affiliated physicians (regardless of location) would reduce our revenue and profits. Frequent or persistent interruptions in our services could cause permanent harm to our reputation and brand and could cause current or
potential customers to believe that our systems are unreliable, leading them to switch to our competitors. Because our customers may use our services for critical healthcare services, any system failures could result in damage to our customers
businesses and reputation. These customers could seek significant compensation from us for their losses, and our agreements with our customers do not limit the amount of compensation that they may receive. Any claim for compensation, even if
unsuccessful, would likely be time consuming and costly for us to resolve.

Our systems are vulnerable to damage or
interruption, including damage and/or interruption due to earthquakes, floods, fires, power loss, telecommunication failures, terrorist attacks, computer viruses, break-ins, sabotage, and acts of vandalism. We do not carry business interruption
insurance to protect us against losses that may result from interruptions in our service as a result of system failures.

Finally, from time to time, we upgrade, replace or expand our information systems. If we fail to successfully manage these activities, we
could experience disruptions and delays in our operations, which could have a material adverse effect on our business.

Hospital privileging requirements or physician licensure laws may limit our market, and the loss of hospital privileges or state
medical licenses held by our affiliated radiologists could have a material adverse affect on our business, financial condition and results of operations.

Each of our affiliated radiologists must be granted privileges to practice at each hospital from which the radiologist receives radiological images and must hold a license in good standing to practice
medicine in the state in which the hospital is located. The requirements for obtaining and maintaining hospital privileges and state medical licenses vary significantly among hospitals and states. If a hospital or state restricts or impedes the
ability of physicians located outside of the United States to obtain privileges or a license to practice medicine at that hospital or in that state, the market for our services could be reduced. In addition, any loss of existing privileges or
medical licenses held by our affiliated radiologists could impair our ability to serve our existing customers and have a material adverse effect on our business, financial condition and results of operations.

Many of the hospital privileges held by our affiliated radiologists were issued pursuant to a standard promulgated by The Joint
Commission that allows the local hospital to rely upon the credentialing and privileging processes performed by us with respect to our affiliated radiologists, a process called privileging by proxy. Essentially, because we are a Joint
Commission-accredited facility, other Joint Commission-accredited facilities can rely on our processes as opposed to duplicating work already performed in accordance with approved standards. However, over the past few years, the Centers for Medicare
and Medicaid Services, or CMS, has increasingly expressed concerns regarding this ability for hospitals to rely on the processes of another institution. In response to the CMS position, The Joint Commission has recently announced that the standards
allowing this practice will expire in July 2010.

In light of the planned changes adopted by The Joint Commission, we are
working with our customers that have historically relied upon these standards to institute new credentialing processes that will help them comply with the new standards once they become effective. Although we have made significant progress, because
of the additional workload that is inherent in any new process, these customers have been requesting to credential and privilege fewer physicians than are currently privileged at those sites. These changes have required us to adapt many of the
administrative processes we perform related to our affiliated physicians, including our credentialing, privileging and scheduling processes. If we are not able to adapt our processes effectively, our financial condition and results of operations
could be negatively impacted.

Medicare and
Medicaid rules governing reassignment of payments could affect our customers ability to collect fees for services provided by our affiliated radiologists and our ability to market our services to our customers.

The majority of our customers are radiology practices. These customers, and not us, typically bill and receive payments from Medicare
and/or Medicaid for professional services which were either performed by our affiliated radiologists that are U.S.-based or performed by the customers radiologist after submission of the preliminary reads provided by our affiliated
radiologists. Medicare and Medicaid generally prohibit a physician who performs a covered medical service from reassigning to anyone else (including to other physicians) the performing physicians right to receive payment directly
from Medicare or Medicaid, except in certain circumstances. We believe that the services provided by our affiliated radiologists satisfy one or more of the exceptions to this prohibition, but the various Medicare carriers and state Medicaid
authorities may interpret these exceptions differently than we do. Because Medicare and Medicaid payments may comprise a significant portion of the total payments received by our customers for the services of our U.S.-based affiliated radiologists,
if it were determined that we do not qualify for an exception, our customers could be prohibited from billing Medicare and/or Medicaid for the services of our U.S.-based affiliated radiologists and this would cause a material adverse effect on our
ability to market our services and on our business and results of operations. Future laws or regulations, moreover, may require that we bill Medicare or Medicaid directly for new services we provide to our customers. Should this occur, we would
either be required to forgo business with such customers or be required to design, develop and implement an appropriate recordkeeping and billing system to bill Medicare and Medicaid.

Medicare reimbursement rules currently provide that the proper Medicare carrier to pay physician claims is the Medicare carrier for the
region in which the physician or practice providing the service is located, rather than the Medicare carrier for the region in which the patient receiving the services is located. Many of our affiliated radiologists are located in a Medicare region
that is different from the Medicare region in which the patient and treating hospital are located. Since it is incumbent on our customers to file with the proper Medicare carrier in order to receive payment, it may be necessary for our customers to
enroll with additional Medicare carriers in order to properly submit claims for reimbursement. To the extent that our customers are unwilling or unable to do so, they may be unwilling to use our services unless we were to submit the claims. Should
this occur, we would either be required to forgo business with such customers or be required to design, develop and implement an appropriate recordkeeping and billing system to bill Medicare and Medicaid. If we are unable to effectively address
these challenges, our business, financial condition and results of operations could be adversely affected.

Changes in
the rules and regulations governing Medicares and Medicaids payment for medical services could affect our revenues, particularly with respect to final reads.

Although most reads we provide are preliminary reads rather than final reads, we are providing an increasing number of final and
sub-specialty reads. Cost containment pressures on Medicare and Medicaid could result in a reduction in the amount that the government will pay for these reads, which could cause pricing pressure on our services. Should that occur, we could be
required to lower our prices, or our customers could elect to provide the reads themselves or obtain such services from one of our competitors, and not utilize the services of our affiliated radiologists, which would have a material adverse effect
on our business, results of operations and financial condition.

We may be subject to less favorable levels of payment
based upon third party payor fee schedules.

Many patients are covered by some form of private or government health
insurance or other third party payment program. Third party payors generally establish fee schedules or other payment authorization methods for various procedures that govern which procedures will be reimbursed by the third party payors and the
amount of reimbursement. To the extent that such schedules impact the rates at which third party payors are willing to pay the healthcare providers with whom we contract to provide imaging services, we are indirectly impacted by such fee schedules.
However, if we were to negotiate direct payment arrangements with third party payors in the future, we would be directly impacted by such schedules. In addition, there is no guarantee that Medicare, state Medicaid programs, or commercial third party
payors will continue to cover professional radiology services. For example, in some states, the Medicaid program budgets have been either cut or funds diverted to other programs, which have resulted in limiting the enrollment of participants. This
has resulted in an increasing number of bankruptcies and difficulty in collecting accounts receivable at hospitals in certain states. Any reduction or elimination in coverage for our services could adversely impact our business.

Changes in the
healthcare industry or litigation reform could reduce the number of diagnostic radiology procedures ordered by physicians, which could result in a decline in the demand for our services, pricing pressure and decreased revenue.

Changes in the healthcare industry directed at controlling healthcare costs and perceived over-utilization of diagnostic radiology
procedures could reduce the volume of radiological procedures performed. For example, in an effort to contain increasing imaging costs, as part of the overall healthcare reform efforts, the U.S. government is considering what some managed care
organizations and private insurers have already adopted, namely, instituting pre-authorization policies which require physicians to pre-clear orders for diagnostic radiology procedures before those procedures can be performed. If pre-clearance
protocols are broadly instituted by Medicare and/or throughout the healthcare industry, the volume of radiological procedures could decrease, resulting in pricing pressure and declining demand for our services. In addition, it is often alleged that
many physicians order diagnostic procedures even when the procedures may have limited clinical utility in large part to establish a record for defense in the event of a medical liability claim. Changes in tort law could reduce the number of
radiological procedures ordered for this purpose and therefore reduce the total number of radiological procedures performed each year, which could harm our operating results.

We may not have adequate intellectual property rights in our brand, which could limit our ability to enforce such rights.

Our success depends in part upon our ability to market our services under the NightHawk brand. However, we believe that the
term NightHawk cannot be afforded trademark protection as it is a generic term used to describe the provision of off-hours radiology services. Other businesses may have prior rights in the brand names that we market under or in similar
names, which could limit or prevent our ability to use these marks, or to prevent others from using similar marks. If we are unable to prevent others from using our brand names, or if others prohibit us from using them, our revenue could be
adversely affected. Even if we are able to protect our intellectual property rights in such brands, we could incur significant costs in doing so.

Any failure to protect our intellectual property rights in our workflow technology could impair its value and our competitive advantage.

We rely heavily on our proprietary workflow technology to distribute radiological images to the appropriately licensed and privileged
radiologist best able to provide the necessary clinical insight in the least amount of turnaround time. If we fail to protect our intellectual property rights adequately, our competitors may gain access to our technology, and our business may be
harmed. We currently do not hold any patents with respect to our technology. Although we have filed an application for a patent covering our workflow technology, we may be unable to obtain patent protection for this technology. In addition, any
patents we may obtain may be challenged by third parties. Accordingly, despite our efforts, we may be unable to prevent third parties from using or misappropriating our intellectual property.

We may in the future become subject to intellectual property rights claims, which could harm our business and operating results.

The information technology industry is characterized by the existence of a large number of patents, trademarks and
copyrights and by frequent litigation based on allegations of infringement or other violations of intellectual property rights. While we are not currently a party to any intellectual property litigation, if a third party asserts that our technology
violates that third-partys proprietary rights, or if a court holds that our technology violates such rights, we may be required to re-engineer our technology, obtain licenses from third parties to continue using our technology without
substantial re-engineering or remove the infringing functionality or feature. In addition, we may incur substantial costs defending any such claim. We may also become subject to damage awards, which could cause us to incur additional losses and harm
our financial position. Monitoring potential infringement of and defending or asserting our intellectual property rights may entail significant expense. We may initiate claims or litigation against third parties for infringement of our proprietary
rights or to establish the validity of our proprietary rights. Any litigation, whether or not it is resolved in our favor, could result in significant expense to us and divert the efforts of our technical and management personnel.

We are dependent on our management team, and the loss of any key member of this team may prevent us from implementing our business
plan in a timely manner.

Our success depends largely upon the continued services of our executive officers,
particularly David Engert, our President and Chief Executive Officer and David Sankaran, our Chief Financial Officer. The loss of either of these executive officers could have a material adverse effect on our business, financial condition,
results of operations and the trading price of our common stock. The search for replacements for any of our executives could be time consuming and could distract our management team from the day-to-day operations of our business.

If we fail to
implement and maintain an effective system of internal controls, we may not be able to report our financial results in an accurate or timely manner, prevent fraud or comply with Section 404 of the Sarbanes-Oxley Act of 2002, which may harm our
business and affect the trading price of our stock.

Effective internal controls are necessary for us to provide
reliable financial reports in a timely manner and to prevent fraud. We cannot assure you that we will maintain an effective system of internal controls in the future. If we fail to adequately staff and train our accounting and finance personnel to
meet the demands of operating as a public company, including the requirements of the Sarbanes-Oxley Act of 2002, or fail to maintain adequate internal controls, any resulting material weakness in internal controls could prevent our management from
concluding the internal controls are effective and impair our ability to prevent material misstatements in our financial statements, which could cause our business to suffer. In addition, investors perceptions that our internal controls are
inadequate or that we are unable to produce accurate financial statements in a timely manner or prevent fraud may negatively affect the trading price of our stock or result in stockholder litigation.

We may be unable to enforce non-compete agreements with our affiliated radiologists.

Our independent contractor agreements with our affiliated radiologists typically provide that the radiologists may not compete with us for
a period of time, typically ranging from 180 days to one year, after the agreements terminate. These covenants not to compete are enforceable to varying degrees from jurisdiction to jurisdiction. In most jurisdictions, a covenant not to compete will
be enforced only to the extent that it is necessary to protect the legitimate business interest of the party seeking enforcement, that it does not unreasonably restrain the party against whom enforcement is sought and that it is not contrary to the
public interest. This determination is made based upon all the facts and circumstances of the specific case at the time enforcement is sought. It is unclear whether our interests will be viewed by courts as the type of protected business interest
that would permit us to enforce a non-competition covenant against the radiologists. A determination that these provisions are not enforceable could have a material adverse effect on us.

If we acquire any companies or technologies in the future, they could prove difficult to integrate, disrupt our business, dilute
stockholder value and adversely affect our operating results.

An element of our strategy is to pursue strategic
acquisitions that are complementary to our business or offer us other strategic benefits. Acquisitions in which we may engage involve numerous risks, including:



| |  |  | difficulties or delays in integrating physician compensation models,
| | - |  | --------------------------------------------------------------------



| |  |  | difficulties in integrating operations, technologies, services and personnel,
| | - |  | -----------------------------------------------------------------------------



| |  |  | diversion of financial and management resources from existing operations,
| | - |  | -------------------------------------------------------------------------



| |  |  | risk of entering new markets,
| | - |  | -----------------------------



| |  |  | potential write-offs of acquired assets,
| | - |  | ----------------------------------------



| |  |  | potential loss of key employees, and
| | - |  | ------------------------------------



| |  |  | inability to generate sufficient revenue to offset acquisition costs.
| | - |  | ---------------------------------------------------------------------

We have in the past experienced, and may experience in the future, these difficulties as we integrate the operations of companies we
acquire.

In addition, if we finance acquisitions by issuing convertible debt or equity securities, our existing stockholders
may be diluted which could affect the market price of our stock. We have made six acquisitions to date, and our management has experienced challenges in completing acquisitions and integrating acquired businesses with our operations. If we fail to
properly evaluate and execute acquisitions, our business and prospects may be harmed.

Enforcement of state and federal
anti-kickback laws may adversely affect our business, financial condition or operations.

Various federal and state
laws govern financial arrangements among healthcare providers. The federal anti-kickback law prohibits the knowing and willful offer, payment, solicitation or receipt of any form of remuneration in return for, or with the purpose to induce, the
referral of Medicare, Medicaid, or other federal healthcare program patients, or in return for, or with the purpose to induce, the purchase, lease or order of items or services that are covered by Medicare, Medicaid, or other federal healthcare
programs. Similarly, many state laws prohibit the solicitation, payment or receipt of remuneration in return for, or to induce the referral of patients in private as well as government programs. Violation of these anti-kickback laws may result in
substantial civil or criminal penalties for individuals or entities and/or exclusion from participating in federal or state healthcare programs. If we are excluded from federal or state healthcare programs, our customers who participate in those
programs would not be permitted to continue doing business with us. We believe that we are operating in compliance with applicable law and believe that our arrangements with providers would not be found to violate the anti-kickback laws. However,
these laws could be interpreted in a manner inconsistent with our operations.

Because our
customers submit claims to the Medicare program based on the services we provide, it is possible that a lawsuit could be brought against us or our customers under the federal False Claims Act, and the outcome of any such lawsuit could have a
material adverse effect on our business, financial condition and operations.

The Federal False Claims Act provides, in
part, that the federal government may bring a lawsuit against any person whom it believes has knowingly presented, or caused to be presented, a false or fraudulent request for payment from the federal government, or who has made a false statement or
used a false record to get a claim approved. The government has taken the position that claims presented in violation of the federal anti-kickback law may be considered a violation of the Federal False Claims Act. The Federal False Claims Act
further provides that a lawsuit brought under that act may be initiated in the name of the United States by an individual who was the original source of the allegations, known as the relator. Actions brought under the Federal False Claims Act are
sealed by the court at the time of filing. The only parties privy to the information contained in the complaint are the relator, the federal government and the court. Therefore, it is possible that lawsuits have been filed against us that we are
unaware of or which we have been ordered by the court not to discuss until the court lifts the seal from the case. Penalties include fines ranging from $5,500 to $11,000 for each false claim, plus three times the amount of damages that the federal
government sustained because of the act of that person. We believe that we are operating in compliance with the Medicare rules and regulations, and thus, the Federal False Claims Act. However, if we were found to have violated certain rules and
regulations and, as a result, submitted or caused our customers to submit allegedly false claims, any sanctions imposed under the Federal False Claims Act could result in substantial fines and penalties or exclusion from participation in federal and
state healthcare programs which could have a material adverse effect on our business and financial condition.

Federal
regulatory and law enforcement authorities have recently increased enforcement activities with respect to Medicare and Medicaid fraud and abuse regulations and other reimbursement laws and regulations, including laws and regulations that govern our
activities and the activities of teleradiologists. These increased enforcement activities may have a direct or indirect adverse affect on our business, financial condition and results of operations.

Additionally, some state statutes contain prohibitions similar to and possibly even more restrictive than the Federal False Claims Act.
These state laws may also empower state administrators to adopt regulations restricting financial relationships or payment arrangements involving healthcare providers under which a person benefits financially by referring a patient to another
person. We believe that we are operating in compliance with these laws. However, if we are found to have violated such laws, our business, results of operations and financial condition would be harmed.

Changes in the governmental interpretation or enforcement of the federal prohibition on physician self-referral may adversely
affect our business, financial conditions or operations.

The federal Stark Law prohibits a physician from
referring Medicare or Medicaid patients for the provision of designated health services by an entity in which the physician has an investment interest or with which the physician has entered into a compensation arrangement. Designated health
services include both the professional and technical components of diagnostic tests using X-rays, ultrasound or other imaging services, CT, MRI, radiation therapy and diagnostic mammography services. Violation of the Stark Law may result in
substantial civil penalties and/or exclusion from participation in federal health care programs for both the referring physicians and any entities that submit technical and/or professional component claims for any diagnostic tests ordered by those
referring physicians. We believe that we have structured our arrangements between our affiliated radiologists and our customers in a manner that complies with applicable law. However, this law could be interpreted in a manner inconsistent with our
arrangements.

The trading price of our common stock has been volatile and will likely remain volatile.

The trading prices of many publicly-traded companies are highly volatile, particularly companies such as ours that
have relatively limited operating histories and are operating in an evolving industry. Since our initial public offering in February 2006, the trading price of our common stock has been subject to wide fluctuations. Factors that will continue to
affect the trading price of our common stock include:



| |  |  | variations in our operating results,
| | - |  | ------------------------------------



| |  |  | announcements of new services, strategic alliances or significant agreements by us or by our competitors,
| | - |  | ---------------------------------------------------------------------------------------------------------



| |  |  | recruitment or departure of key personnel,
| | - |  | ------------------------------------------



| |  |  | changes in the estimates of our operating results or changes in recommendations by any securities analysts that follow our common stock, and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | market conditions in our industry, the industries of our customers and the economy as a whole.
| | - |  | ----------------------------------------------------------------------------------------------

In addition, if the market for healthcare stocks or healthcare services or the stock market in general experiences loss of investor
confidence, the trading price of our common stock could decline for reasons unrelated to our business, operating results or financial condition. The trading price of our common stock might also decline in reaction to events that affect other
companies in our industry even if these events do not directly affect us.

We may need
additional capital, which may not be available to us.

We currently anticipate that our existing capital resources and
cash generated from future operations will be sufficient to meet our liquidity needs for at least the next 12 months. However, we may need to raise additional funds if our estimates of revenues, working capital and/or capital expenditure
requirements change or prove inaccurate or in order for us to respond to unforeseen technological or marketing hurdles or to take advantage of unanticipated opportunities. There can be no assurance that any such funds will be available at the time
or times needed or available on terms acceptable to us.

Furthermore, if our total leverage ratio under our credit agreement
exceeds the thresholds provided for in the credit agreement, we may be required to repay all or a portion of our term loan borrowings under our credit agreement. See Part IItem 2Managements Discussion and Analysis of
Financial Condition and Results of OperationsLiquidity and Capital ResourcesFinancial Condition and Liquidity of this report for more information. Our financial results will be impacted as a result of the settlement with SPRPA. In
the first six months of 2010, we generated an aggregate of $10.2 million, or approximately 14%, of our total revenue, from our original agreements with SPRPA. As a result of the settlement, beginning July 1, 2010, we will not derive any revenue
from such agreements or related profits that we have historically generated from SPRPA. As a result, our total leverage ratio could exceed thresholds that would trigger obligations to repay some or all of our borrowings under our credit agreement.
If we are required to make a mandatory repayment of a portion of the principal of our term loan, or if our obligations under our term loan are accelerated as a result of our default, our financial condition would be materially adversely impacted.

If securities analysts do not publish research or reports about our business, or if they downgrade our stock, the price
of our stock could decline.

The trading market for our common stock will rely in part on the availability of research
and reports that third-party industry or financial analysts publish about us. There are many large, publicly-traded companies active in the healthcare services industry, which may mean it will be less likely that we receive widespread analyst
coverage. Furthermore, if one or more of the analysts who do cover us downgrade our stock, our stock price would likely decline. If one or more of these analysts cease coverage of our company, we could lose visibility in the market, which in turn
could cause our stock price to decline.

Adverse changes in general economic conditions could adversely affect our
operating results.

Our success depends upon our ability to continue to provide our services to our customers and the
willingness of our customers to engage us for these services. The willingness and ability of our customers to engage us for our services depends upon a number of factors, including broader economic conditions, conditions of the radiology marketplace
and perceptions of such conditions by our customers. Adverse changes in the broader U.S. economy or in the radiology marketplace may have an adverse impact on the behavior of our customers and the extent to which they are willing to engage us for
our services. In addition, we may experience difficulty collecting accounts receivable in a timely manner, or at all, if our customers are adversely affected by prevailing economic conditions. Any of these factors could, in turn, have a material
adverse effect on our business, financial condition, results of operations and cash flows.

A change in our customer
composition or general economic conditions may impact our collection rates.

An increasing number of our customers are
hospitals or hospital groups. As changes occur in general economic conditions, hospitals may be required to modify their budgets and/or move funds to other programs as directed by their management or changes in government funding. Recently, we have
noticed an increasing number of hospitals becoming insolvent as government funds decrease to hospitals in certain states. If this trend continues and impacts our customers, our collection rates may decrease and our bad debt expense increase which,
in turn, could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We are exposed to foreign currency exchange risks, which could harm our business and operating results.

We maintain significant operations in Australia and Switzerland, and are exposed to adverse changes in exchange rates associated with the
expenses of our operations in these countries. However, we do not currently engage in any hedging transactions to mitigate these risks. Although from time to time we review our foreign currency exposure and evaluate whether we should enter into
hedging transactions, we may not adequately hedge against any future volatility in currency exchange rates and, if we engage in hedging transactions, the transactions will be based on forecasts which later may prove to be inaccurate. Any failure to
hedge successfully or anticipate currency risks properly could adversely affect our operating results.

In addition, 20% of
our affiliated radiologists live in Australia and Switzerland, but receive compensation from us in U.S. dollars. Any relative weakness in the U.S. dollar compared to the Australian dollar or Swiss franc may increase the cost of living for our
affiliated radiologists and make it less attractive for our affiliated radiologists to sign or renew their service contracts with us.
