ON ASSIGNMENT, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1.Financial Statement Presentation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information, the instructions to Form 10-Q and Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. The information reflects all normal and recurring adjustments which, in the opinion of management, are necessary for a fair presentation of the financial position of On Assignment, Inc. and its subsidiaries (the Company) and its results of operations for the interim dates and periods set forth herein. The results for the three months ended March 31, 2012 are not necessarily indicative of the results to be expected for the full year or any other period. This Quarterly Report on Form 10-Q should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2011.

2. Accounting Standards Updates.  

In December 2011, the Financial Accounting Standards Board (FASB) issued FASB Accounting Standards Update (ASU) No. 2011-11, Balance Sheet (Topic 210)—Disclosures about Offsetting Assets and Liabilities. ASU 2011-11 requires an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position. Entities are required to disclose both gross and net information about these instruments. ASU 2011-11 is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The adoption of this ASU is not expected to have a material impact on the Company's consolidated financial statements.

In September 2011, the FASB issued ASU No. 2011-08, Testing Goodwill for Impairment (Topic 350) — Intangibles—Goodwill and Other (ASU 2011-08), to allow entities to use a qualitative approach to test goodwill for impairment. ASU 2011-08 permits an entity to first perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If so, it is necessary to perform the currently prescribed two-step goodwill impairment test. Otherwise, the two step goodwill impairment test is not required. ASU 2011-08 is effective for the Company in the first quarter of fiscal 2012 and earlier adoption is permitted. The adoption of ASU 2011-08 did not have a material impact on the consolidated financial statements.

In June 2011, the FASB issued ASU No. 2011-05, Presentation of Comprehensive Income (Topic 220) — Comprehensive Income (ASU 2011-05), to require an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. ASU 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of equity. ASU 2011-05 is effective for the Company in the first quarter of fiscal 2012 and should be applied retrospectively. In December 2011, the FASB issued ASU 2011-12, Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05, which defers certain aspects of ASU 2011-05 related to the presentation of reclassification adjustments. The adoption of ASU 2011-05 only impacted the presentation of the consolidated financial statements.

In May 2011, the FASB issued ASU No. 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S.GAAP and International Financial Reporting Standards (Topic 820) — Fair Value Measurement (ASU 2011-04), to provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are similar between U.S. Generally Accepted Accounting Principles and International Financial Reporting Standards. ASU 2011-04 changes certain fair value measurement principles and enhances the disclosure requirements particularly for Level 3 fair value measurements. ASU 2011-04 became effective for the Company in the first quarter of fiscal 2012; see Note 6 for required disclosures.

3.Acquisitions.On March 20, 2012, On Assignment entered into an Agreement of Merger (the Merger Agreement) with Apex Systems, Inc., a Virginia corporation (Apex), OA Acquisition Corp., a Virginia corporation (Merger Sub), and Jeffrey E. Veatch as the Shareholder Representative. Pursuant to the Merger Agreement, the Merger Sub will merge with and into Apex (the Merger), with Apex continuing as the surviving entity. As a result of the Merger, Apex will become a wholly owned subsidiary of On Assignment. As more fully described in our Proxy Statement, filed with the SEC on April 13, 2012, and in the Merger Agreement, under the Merger Agreement the aggregate consideration to be received by Apex shareholders is $217 million of On Assignment common stock and $383 million in cash, subject to adjustment in certain circumstances. The obligation of On Assignment and Merger Sub to complete the Merger is subject to the satisfaction or waiver of a number of conditions set forth in the Merger Agreement, including the approval by On Assignment’s shareholders of the issuance of common stock to Apex shareholders in the Merger, the receipt of proceeds by On Assignment of debt financing in the aggregate principal amount of $540 million and other customary closing conditions.  In connection with the execution of the Merger Agreement, On Assignment obtained a commitment for a new $540 million senior secured credit facility. The credit facility provides for a $75 million revolving credit facility, $100 million term loan A and $365 million term loan B. The proceeds of the credit facility, which are to be funded in connection with the completion of the Merger, will be used to finance the cash portion of the purchase price, to repay existing indebtedness of On Assignment and Apex Systems and to pay fees and expenses in connection with the transaction. The Merger is expected to close during the second quarter of 2012. The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, a copy of which is attached to the Current Report on Form 8-K filed on March 26, 2012.

On February 28, 2011, the Company acquired all of the outstanding shares of Valesta, a privately-owned provider of specialized clinical research staffing headquartered in Belgium. The primary reasons for the acquisition were to expand the Life Sciences business operations and to leverage the Company’s infrastructure. The purchase price for Valesta totaled $23.7 million comprised of $16.8 million in cash paid at closing, plus potential future earn-out consideration of $6.9 million (the maximum earn-out is capped at a Euro value of 5.0 million or approximately $6.7 million at March 31, 2012 exchange rates) based on estimated financial performance of Valesta through 2013. Acquisition costs related to this transaction totaled approximately $0.4 million and were expensed in 2011. Goodwill is not deductible for tax purposes. The results of operations for the acquisition have been combined with those of the Company since the acquisition date.

On July 31, 2011, the Company acquired all of the outstanding shares of HealthCare Partners (HCP), a privately-owned provider of physician staffing headquartered in Atlanta, Georgia. The primary reasons for the acquisition were to expand the Physician segment business operations geographic coverage and to leverage the Company’s infrastructure. The estimated purchase price for HCP was approximately $19.1 million comprised of $15.7 million in cash paid at closing, plus potential future earn-out consideration of $3.4 million (the maximum earn-out is capped at $3.7 million) based on estimated financial performance of HCP through 2013. Acquisition costs related to this transaction totaled approximately $57,000 and were expensed in 2011. Goodwill is deductible for tax purposes. The results of operations for the acquisition have been combined with those of the Company since the acquisition date.

6

Assets and liabilities of the acquired companies were recorded at their estimated fair values at the dates of acquisition. The excess purchase price over the fair value of net tangible assets and identifiable intangible assets acquired has been allocated to goodwill. The fair value assigned to identifiable intangible assets was determined primarily by using a discounted cash flow method. The Company intends to discontinue the use of the HCP tradename during 2012. The Company’s allocation of the purchase price for HCP is preliminary, as the amounts related to working capital and income taxes are still being finalized. Any measurement period adjustments will be recorded retrospectively to the acquisition date. During the quarter ended March 31, 2012, the Company adjusted Valesta’s purchase price allocation. The adjustment was to recognize the tax impact of the amortization of identifiable intangible assets. The adjustment was not material and had no impact on the consolidated statement of operations; accordingly it is not presented retrospectively.

The fair value of earn-out obligations is based on the present value of the expected future payments to be made to the sellers of the acquired businesses in accordance with the respective purchase agreements. See Note 6 for further information regarding the fair value of earn-outs and the level 3 rollforward disclosure.

The following table summarizes (in thousands) the purchase price allocation for the acquisitions of HCP, which is subject to finalization during the measurement period and Valesta:

	2011 Acquisitions
	HCP		Valesta		Total
Current assets	$	3,941	$	6,332	$	10,273

4.Long-Term Debt.Long-term debt as of March 31, 2012 and December 31, 2011, consisted of the following (in thousands):

	March 31, 2012		December 31, 2011
Senior Secured Debt:
$75 million revolving credit facility, due December 2015	$	38,000	$	43,000
$50 million term loan facility, due December 2015		42,500		43,750
Total	$	80,500	$	86,750

As of March 31, 2012 and December 31, 2011, the Company was in compliance with all of its financial covenants.

5.Derivative Instruments.  The Company utilizes derivative financial instruments to manage interest rate risk. The Company does not use derivative financial instruments for trading or speculative purposes, nor does it use leveraged financial instruments. The Company reports its derivative instruments separately as assets and liabilities unless a legal right of set-off exists under a master netting agreement enforceable by law. The Company’s derivative instruments are recorded at their fair value, and are included in other long-term liabilities and other liabilities in the Condensed Consolidated Balance Sheets.

On February 18, 2011, the Company entered into an interest rate swap agreement to hedge a portion of its interest rate exposure on its senior secured debt (the 2011 Interest Rate Swap). The 2011 Interest Rate Swap has a notional amount of $25.0 million and fixes a portion of the Company’s base borrowing rate, which is a floating rate based on a LIBOR swap rate that resets periodically.  The 2011 Interest Rate Swap was designated as a hedging instrument for accounting purposes and is accordingly accounted for as a cash flow hedge. The effective portion of unrealized losses on this interest rate swap agreement are included in accumulated other comprehensive income until the periodic interest settlements occur, at which time they will be recorded as interest expense in the Consolidated Statements of Operations and Comprehensive Income. The Company expects to reclassify losses of $0.3 million (pretax) from Accumulated Other Comprehensive Income to interest expense in the Consolidated Statements of Operation within the next twelve months.

As a result of the use of derivative instruments, the Company is exposed to risk that the counterparties will fail to meet their contractual obligations. To mitigate the counterparty credit risk, the Company only enters into contracts with carefully selected major financial institutions based upon their credit ratings and other factors, and continually assess the creditworthiness of counterparties. As of March 31, 2012, the counterparty to the interest rate swap had investment grade ratings and has performed in accordance with their contractual obligations.

The fair values of derivative instruments in the Consolidated Balance Sheets are as follows (in thousands):

Derivative in Cash Flow Hedging Relationships
	Balance Sheet Classification	March 31, 2012	December 31, 2011
2011 Interest Rate Swap - current portion	Other Liabilities	$              344	$            310
2011 Interest Rate Swap - long-term portion	Other Long-Term Liabilities	264	298
		$              608	$            608

The following tables reflect the effect of derivative instruments on the Consolidated Statements of Operations and Comprehensive Income for the three months ended March 31, 2012 and 2011 (in thousands):

Derivatives in Cash Flow Hedging Relationships	Amount of Gain/Loss Recognized in Accumulated Other Comprehensive Income on Derivative

		Three Months Ended March 31,
		2012		2011
2011 Interest Rate Swap	Interest expense	$	90	$	31

6.Fair Value Measurements.  The valuation techniques utilized are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect internal market assumptions. These two types of inputs create the following fair value hierarchy:

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

Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data.

Level 3: Unobservable inputs that are not corroborated by market data.

8

The recorded values of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate their fair value based on their short-term nature. Long-term debt recorded in the Company’s Condensed Consolidated Balance Sheets at March 31, 2012 was $80.5 million. The fair value of the long-term debt was determined using the quoted price technique, based on Level 2 inputs including the yields of comparable companies with similar credit characteristics, was $78.5 million.

The interest rate swap liability is measured using the income approach. The fair value reflects the estimated amounts that the Company would pay or receive based on the present value of the expected cash flows derived from market rates and prices.  As such, this derivative instrument is classified within Level 2.  

The Company has obligations, to be paid in cash, to the former owners of acquired companies if certain future financial goals are met.  The fair value of this contingent consideration is determined using an expected present value technique.  Expected cash flows are determined using the probability - weighted average of possible outcomes that would occur should certain financial metrics be reached.  There is no market data available to use in valuing the contingent consideration, therefore, the Company developed its own assumptions related to the future financial performance of the businesses to evaluate the fair value of these liabilities.  As such, the contingent consideration is classified within Level 3.  

In connection with estimating the fair value of the contingent consideration, the Company develops various scenarios (base case, downside case, and upside case) and weights each according to the probability of occurrence. The probabilities range from 5 percent to 85 percent, with the most significant weighting given to the base case at 80-85 percent. These scenarios are developed based on the expected financial performance of the acquired companies, with revenue growth rates being a primary input to the calculation. These revenue growth rates range from 1.0 percent to 29.4 percent. An increase or decrease in the probability of achievement of any of these scenarios could result in a significant increase or decrease to the estimated fair value. 

The fair value is reviewed on a quarterly basis based on most recent financial performance of the most recent fiscal quarter. An analysis is performed at the end of each fiscal quarter to compare actual results to forecasted financial performance. If performance has deviated from projected levels, the valuation is updated for the latest information available.

The significant assumptions that may materially affect the fair value are developed in conjunction with the guidance of the division presidents, division vice presidents, and chief financial officer to ensure that the most accurate and latest financial projections are used and compared with the most recent financial results in the fair value measurement.

The liabilities for the contingent consideration were established at the time of the acquisition and are evaluated at each reporting period.  The current liability is included in the Condensed Consolidated Balance Sheets in the current portion of accrued earn-outs and the non-current portion is included in accrued earn-outs. Fair value adjustments are included in the Condensed Consolidated Statements of Operations and Comprehensive Income in selling, general and administrative expenses.

The assets and liabilities measured at fair value on a recurring basis are as follows (in thousands):

Goodwill and other intangible assets having an indefinite useful life are not amortized for financial statement purposes. Goodwill and intangible assets with indefinite lives are reviewed for impairment on an annual basis as of December 31 and whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. There were no triggering events that required an interim impairment analysis during the current period.

8.Incentive Award Plan and Employee Stock Purchase Plan. The Company granted discrete stock-based awards to its Chief Executive Officer (CEO) as follows: (i) a market based award in 2010, which as of March 31, 2012 was valued at $0.5 million, which is the full value of the award based on the achievement of defined market targets. This award is expensed over a service period of 2.6 yearsand the number of shares will be determined by dividing $0.5 million by the closing price of the Company stock on February 1, 2013, (ii) a performance based award on March 8, 2011, which had a grant date fair market value of $1.0 million and was expensed over a service period of 9.9 months. The Company met the financial performance objectives during the twelve month period ending December 31, 2011 and the number of shares will be determined by dividing $0.5 million by the closing price of the Company’s stock on each February 1, 2013 and February 1, 2014, and (iii) a performance based award on March 23, 2012, which had a grant date fair market value of $1.5 million. The number of shares will be determined by dividing $0.5 million by the closing price of the Company’s stock on each of February 1, 2013, February 1, 2014 and February 1, 2015 contingent upon the Company meeting certain financial performance objectives measured over the twelve month period between January 1, 2012 and December 31, 2012. The Company classifies these awards as liability awards until the number of shares is determined. The liability of $1.4 million related to these awards is included in other accrued expenses and other long-term liabilities in the accompanying Condensed Consolidated Balance Sheets as of March 31, 2012.

On March 5, 2012, the CEO was awarded 45,372 RSUs with a grant date fair market value of $0.6 million, which will vest in two equal components of $0.3 million on January 1, 2013 and January 1, 2014, contingent upon the Company achieving certain performance objectives based on adjusted EBITDA (earnings before interest, taxes, depreciation, and amortization of identifiable intangible assets, “EBITDA”, plus equity-based compensation expense, impairment charges and acquisition related costs)approved by the Compensation Committee over the twelve-month period ending December 31, 2012. On January 3, 2012, the CEO was awarded 72,596 RSUs with a grant date fair market value of $0.8 million, which will vest on January 1, 2013, based on the Company achieving positive EBITDA during the twelve month period ending December 31, 2012. The grant-date fair market value of the RSUs described in this paragraph is being expensed over the vesting term, based on an estimate of the percentage achievement of the applicable performance targets. All awards are subject to the CEO’s continued employment through applicable vesting dates. All awards may vest on an accelerated basis in part or in full upon the occurrence of certain events.

In the first quarter of 2012, the Company granted awards to certain other executive officers with an aggregate grant-date fair value of $1.7 million. Of the $1.7 million, $0.9 million will vest in three annual increments subject to continued employment on each succeeding grant-date anniversary. The remaining $0.8 million will vest on January 3, 2013, subject to continued employment and the Company attaining certain performance objectives during 2012, as approved by the Compensation Committee. Compensation expense for the performance-based component of these awards is recognized over the vesting period, based on an estimate of the percentage achievement of the targets for these awards.

On March 31, 2012 the Company issued 108,164 shares of common stock under the On Assignment 2010 Employee Stock Purchase Plan (ESPP).  

Compensation expense charged to operations related to stock-based compensation, including the ESPP, was $1.2 million and $1.6 million for the three months ended March 31, 2012 and March 31, 2011, respectively. Stock –based compensation is included in the Condensed Consolidated Statements of Operations and Comprehensive Income in selling, general and administrative expenses. 

9.Commitments and Contingencies.  The Company is partially self-insured for its workers’ compensation liability and its medical malpractice liability. The Company accounts for claims incurred but not reported based on estimates derived from historical claims experience and current trends of industry data. Changes or differences in estimates and actual payments for claims are recognized in the period that the estimates changed or the payments were made. The self-insurance claim liability was approximately $10.2 million and $10.4 million as of March 31, 2012 and December 31, 2011, respectively. Additionally, the Company has letters of credit outstanding to secure obligations for workers’ compensation claims with various insurance carriers. The letters of credit outstanding were $2.4 million as of March 31, 2012 and December 31, 2011.

The Company is involved in various legal proceedings, claims and litigation arising in the ordinary course of business. Based on the facts currently available, the Company does not believe that the disposition of matters that are pending or asserted will have a material effect on its financial position, results of operations or cash flows.

As described in Note 3 and in the Proxy Statement, filed with the SEC onApril 13, 2012, the Company entered into an Agreement of Merger on March 20, 2012 to acquire Apex Systems, Inc. for a combination of $217 million of Company Common stock and $383 million in cash, subject to adjustment in certain circumstances. Under the Agreement of Merger, the Company will be required to pay a termination fee of $21.0 million to Apex Systems, Inc. if the transaction does not close under certain circumstances as outlined in the Agreement of Merger.

11

The Company is subject to earn-out obligations entered into in connection with certain of its acquisitions. If the acquired businessesmeet predetermined targets, the Company is obligated to make additional cash payments in accordance with the terms of such earn-out obligations. As of March 31, 2012, the Company has potential future earn-out obligations of approximately $10.4 million through 2013.

The Company has entered into various non-cancelable operating leases, primarily related to its facilities and certain office equipment used in the ordinary course of business.

10.Earnings per share.Basic earnings per share are computed based upon the weighted average number of common shares outstanding. Diluted earnings per share are computed based upon the weighted average number of common shares outstanding and dilutive common share equivalents (consisting of incentive stock options, non-qualified stock options, restricted stock awards and units and employee stock purchase plan shares) outstanding during the periods using the treasury stock method.

The following is a reconciliation of the shares used to compute basic and diluted earnings per share (in thousands):

	Three Months Ended
	March 31,
	2012		2011
Weighted average number of common shares
outstanding used to compute basic earnings per share		37,269		36,623
Dilutive effect of stock-based awards		885		806
Number of shares used to compute diluted earnings per share		38,154		37,429

The following table presents the weighted average share equivalents outstanding during each period that were excluded from the computation of diluted earnings per share because the exercise price for these options was greater than the average market price of the Company’s shares of common stock during the respective periods that became anti-dilutive when applying the treasury stock method (in thousands):

	Three Months Ended
	March 31,
	2012		2011
Anti-dilutive common share equivalents outstanding		710		1,261

11. Income Taxes. For interim reporting periods, the Company prepares an estimate of the full-year income and the related income tax expense for each jurisdiction in which the Company operates.  Changes in the geographical mix, permanent differences or estimated level of annual pretax income can impact the Company’s actual effective rate.

As of March 31, 2012 and December 31, 2011, the estimated value of the Company’s uncertain tax positions is a liability of $0.2 million, which includes penalties and interest, all of which is included in other long-term liabilities.  If the Company’s positions are sustained by the taxing authority in favor of the Company, the entire $0.2 million would reduce the Company’s effective tax rate. The Company recognizes accrued interest and penalties related to uncertain tax positions in income tax expense.

The Company is subject to taxation in the United States and various states and foreign jurisdictions. The Internal Revenue Service (IRS) has examined and concluded all tax matters for years through 2006.  The IRS has commenced an examination of the Company’s U.S. income tax returns for the 2009 tax year. Open tax years related to federal, state and foreign jurisdictions remain subject to examination but are not considered material.

12.Segment Reporting.The Company has four reportable segments: Life Sciences, Healthcare, Physician and IT and Engineering. The Company’s management evaluates the performance of each segment primarily based on revenues, gross profit and operating income. The information in the following table is derived directly from the segments’ internal financial reporting used for corporate management purposes.

OVERVIEW

On Assignment, Inc., is a leading global provider of highly skilled, hard-to-find professionals in the growing life sciences, healthcare, and technology sectors, where quality people are the key to success. The Company goes beyond matching résumés with job descriptions to match people they know into positions they understand, for contract, contract-to-hire, and direct hire assignments. Our business currently consists of four operating segments: Life Sciences, Healthcare, Physician, and IT and Engineering.

The Life Sciences segment includes our domestic and international life science staffing lines of business. We provide locally-based, contract life science professionals to clients in the biotechnology, pharmaceutical, food and beverage, medical device, personal care, chemical, nutraceutical, materials science, consumer products, environmental petrochemical and contract manufacturing industries. Our contract professionals include chemists, clinical research associates, clinical lab assistants, engineers, biologists, biochemists, microbiologists, molecular biologists, food scientists, regulatory affairs specialists, lab assistants and other skilled scientific professionals.

The Healthcare segment includes our Nurse Travel and Allied Healthcare lines of business. We offer our healthcare clients contract professionals, both locally-based and traveling, from a number of healthcare medical financial and allied occupations. Our contract professionals include nurses, specialty nurses, health information management professionals, dialysis technicians, surgical technicians, imaging technicians, x-ray technicians, medical technologists, phlebotomists, coders, billers, claims processors and collections staff.

The Physician segment consists mainly of VISTA Staffing Solutions, Inc. and HealthCare Partners (HCP) which are leading providers of physician staffing, known as locum tenens coverage, and permanent physician search services based in Salt Lake City, Utah and Atlanta, Georgia. We provide short and long-term locum tenens coverage and full-service physician search and consulting services in the United States with capabilities in Australia and New Zealand. The Physician segment works with physicians from nearly all medical specialties to place them in hospitals, community-based practices, and federal, state and local facilities.

The IT and Engineering segment consists mainly of Oxford Global Resources, Inc. (Oxford) which delivers high-end consultants with expertise in specialized information technology, software and hardware engineering, mechanical, electrical, validation and telecommunications engineering fields. We combine international reach with local depth, serving clients through a network of Oxford International recruiting centers in the United States and Europe, and Oxford & Associates branch offices in major metropolitan markets across the United States. Oxford is based in Beverly, Massachusetts.

First Quarter 2012 Update

In the first quarter, consolidated revenues and earnings per share grew year-over-year and sequentially over the fourth quarter of 2011.  We saw demand strengthen in all of the segments we serve.

Apex Systems, Inc. Merger Agreement

On March 20, 2012, On Assignment entered into an Agreement of Merger (the Merger Agreement) with Apex Systems, Inc., a Virginia corporation (Apex), OA Acquisition Corp., a Virginia corporation (Merger Sub), and Jeffrey E. Veatch as the Shareholder Representative. Pursuant to the Merger Agreement, the Merger Sub will merge with and into Apex (the Merger), with Apex continuing as the surviving entity.  As a result of the Merger, Apex will become a wholly owned subsidiary of On Assignment. As more fully described in our Proxy Statement, filed with the SEC on April 13, 2012, and in the Merger Agreement, under the Merger Agreement the aggregate consideration to be received by Apex shareholders is $217 million of On Assignment common stock and $383 million in cash, subject to adjustment in certain circumstances. The obligation of On Assignment and Merger Sub to complete the Merger is subject to the satisfaction or waiver of a number of conditions set forth in the Merger Agreement, including the approval by On Assignment’s shareholders of the issuance of common stock to Apex shareholders in the Merger, the receipt of proceeds by On Assignment of debt financing in the aggregate principal amount of $540 million and other customary closing conditions.  In connection with the execution of the Merger Agreement, On Assignment obtained a commitment for a new $540 million senior secured credit facility. The credit facility provides for a $75 million revolving credit facility, $100 million term loan A and $365 million term loan B. The proceeds of the credit facility, which are to be funded in connection with the completion of the Merger, will be used to finance the cash portion of the purchase price, to repay existing indebtedness of On Assignment and Apex Systems and to pay fees and expenses in connection with the transaction. The Merger is expected to close during the second quarter of 2012. The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, a copy of which is attached to the Current Report on Form 8-K filed on March 26, 2012.

Seasonality

Demand for our staffing services historically has been lower during the first and fourth quarters due to fewer business days resulting from client shutdowns, adverse weather conditions and a decline in the number of contract professionals willing to work during the holidays. As is common in the staffing industry, we run special incentive programs to keep our contract professionals, particularly nurses, working through the holidays. Demand for our staffing services usually increases in the second and third quarters of the year. In addition, our cost of services typically increases in the first quarter primarily due to the reset of payroll taxes.

CHANGES IN RESULTS OF OPERATIONS FOR THE THREE MONTHS ENDED MARCH 31, 2012 COMPARED WITH THE THREE MONTHS ENDED MARCH 31, 2011

Revenues

	Three Months Ended
	March 31,						Change
	2012			2011			$			%
Revenues by segment (in thousands):
Life Sciences		$	41,351		$	32,957		$	8,394	25.5	%
Healthcare			22,879			19,844			3,035	15.3	%

Total		$	167,078		$	129,438		$	37,640	29.1	%

Revenues increased $37.6 million, or 29.1 percent, mainly due to organic growth, as well as growth from our acquisitions of Valesta and HCP in 2011. Organic growth accounted for $26.5 million of the increase in revenues. The IT and Engineering segment accounted for $18.6 million or 70 percent of the organic growth. Acquisition growth accounted for the remaining $11.1 increase in revenues. Valesta revenues for the three months ended March 31, 2012 were $6.5 million, compared with $2.0 million for the same period in 2011. Valesta was acquired during the first quarter of 2011 and is reported in the Life Sciences segment. HCP revenues for the three months ended March 31, 2012 were $6.6 million. HCP was acquired on July 31, 2011 and is reported in the Physician segment.

Life Sciences segment revenues increased $8.4 million, or 25.5 percent, comprised of a 17.8 percent increase in the average number of contract professionals on assignment and a 2.7 percent increase in the average bill rate. The year-over-year increase in revenues was attributable to $6.5 million in revenues for the three months ended March 31, 2012 from the Valesta acquisition compared with $2.0 million in the same period of 2011, and increased demand for our service offerings as our clients’ end markets have improved in the first quarter of 2012 with the economic recovery.

Healthcare segment (comprised of our Nurse Travel and Allied Healthcare lines of business) revenues increased $3.0 million, or 15.3 percent. Nurse Travel revenues increased $0.6 million, or 6.3 percent, to $10.3 million, comprised of a 4.5 percent increase in the average number of nurses on assignment and a 2.1 percent increase in the average bill rate. Allied Healthcare revenues increased $2.4 million, or 23.9 percent, to $12.6 million, comprised of a16.0 percent increase in the average number of contract professionals on assignment, a 0.8 percent increase in the average bill rate, and an increase in conversion and permanent placement revenue. The increase in revenues was attributable to improved economic trends in the healthcare sector, which resulted in a higher number of contract professionals on assignment, open orders and average bill rates. The allied healthcare operating environment continued to demonstrate signs of improvement as economic trends in our end markets showed signs of stabilization and growth as evidenced by year-over-year growth in the number of contractors and clients on billing, average bill rate and billable hours. Although the Healthcare segment remains soft, we continue to see signs of improvement in demand for contract professionals.

15

Physician segment revenues increased $7.6 million, or 45.8 percent, comprised of a 56.7 percent increase in the average number of physicians placed and working, partially offset by a 4.3 percent decrease in bill rate. The increase in Physician segment revenues was primarily due to $6.6 million from our HCP acquisition. Revenues from the legacy physician staffing business increased $1.0 million, or 5.9 percent, primarily due to a 4.9 percent increase in average bill rate and a $0.3 million increase in direct hire and conversation fee revenues. This increase was partially offset by a 4.3 percent decrease in the average number of physicians placed and working.

 IT and Engineering segment revenues increased $18.6 million, or 31.0 percent, comprised of a 25.2 percent increase in the average number of contract professionals on assignment and a 3.9 percent increase in average bill rate. Because many of our placements involve capital projects, we believe that one reason for the demand for our services has increased with the economic recovery is that more companies have increased their capital spending. We have continued to focus on diversifying this segment across clients and industries and have selectively added staffing consultants necessary for current and future growth. In the April Staffing Industry Analysts report, the US IT Staffing market in 2012 is predicted to surpass its 2000 peak set at the height of the dot-com boom.

	2012				2011
	Gross Profit		Gross Margin		Gross Profit		Gross Margin
Gross Profit by segment (in thousands):
Life Sciences	$	13,839		33.5%	$	11,270		34.2%
Healthcare		6,340		27.7 %		5,627		28.4%
Physician		7,499		31.1 %		5,299		32.1 %
IT and Engineering		27,370		34.8 %		20,958		34.9 %
Total	$	55,048		32.9 %	$	43,154		33.3 %

The year-over-year gross profit increase was primarily due to higher revenues, which was partially offset by a 39 basis point contraction in consolidated gross margin.  The decrease in gross margin was attributable to the reduction in direct hire and conversion fee revenues as a percentage of revenues for the Life Sciences segment, increased non-billable expenses and other employee expenses for the Healthcare and Physician segments, and a greater concentration of governmental work for the Physician segment.

Life Sciences segment gross profit increased $2.6 million, or 22.8 percent. The increase in gross profit was primarily due to a 25.5 percent increase in revenues, which was partially offset by a 73 basis point contraction in gross margin. The contraction in gross margin was due to a $0.7 million increase in payroll taxes related to higher European payroll tax rates for Valesta employees, a $0.3 million increase in travel related expenses, a $0.2 million increase in holiday pay, and the decrease in higher margin direct hire and conversion fee revenues as a percentage of revenues from 7.9 percent in 2011 to 6.7 percent in 2012. This contraction in gross margin was partially offset by a 6.8 percent increase in bill/pay spread.

Healthcare segment gross profit increased $0.7 million, or 12.7 percent. The increase in gross profit was due to a 15.3 percent increase in revenues, partially offset by a 65 basis point contraction in gross margin. The contraction in gross margin was mainly due to a $0.4 million, or 25.8 percent increase in non-billable other employee expenses, and a $0.3 million or 26.8 percent increase in non-billable travel related expenses. Within this segment, Allied Healthcare gross profit increased 27.2 percent, while gross margin increased 84 basis points, as a result of improvements in pricing, slightly offset by an increase in assignment related expenses. Nurse Travel gross profit decreased 6.1 percent and gross margin decreased 296 basis points, as a result of pricing pressures and increases in assignment related expenses.

Physician segment gross profit increased $2.2 million, or 41.5 percent. The increase in gross profit was due to a $7.6 million, or 45.8 percent increase in the segment revenues, partially offset by a 95 basis point contraction in gross margin. The contraction in gross margin was primarily due to an 11.9 percent decrease in bill/pay spread in part related to a greater concentration of government work at HCP. The physician segment also experienced an increase in non-billable expenses and other employee expenses. This contraction in gross margin was partially offset by a $0.4 million, or 53.1 percent increase in direct hire and conversion fee revenues.

IT and Engineering segment gross profit increased $6.4 million, or 30.6 percent, primarily due to an $18.6 million, or 31.0 percent increase in revenues, partially offset by an 11 basis point contraction in gross margin. The contraction in gross margin was primarily due to a $0.8 million increase in payroll taxes and unemployment insurance, partially offset by a 6.0 percent increase in bill/pay spread.

Selling, General and Administrative Expenses

For the quarter ended March 31, 2012, SG&A expenses increased $8.3 million, or 22.7 percent, to $45.1 million from $36.8 million for the same period in 2011. The increase in SG&A expenses was primarily due to (i) $5.0 million, or 18.0 percent increase in compensation and benefits and (ii) $2.5 million in acquisition costs primarily related to pending acquisition of Apex Systems. The increase in compensation and benefits was due to (i) a $3.1 million increase in compensation expenses primarily as a result of increased headcount related to the Valesta and HCP acquisitions and headcount additions to support anticipated higher growth in certain segments, and (ii) a $1.9 million increase in bonuses and commissions as a result of increased revenue and the anticipated attainment of incentive compensation targets. Additionally, the non-compensation and benefits related SG&A expenses increased $1.1 million as a result of the Valesta and HCP acquisitions. Total SG&A expenses as a percentage of revenues decreased to 27.0 percent for the three months ended March 31, 2012 compared with 28.4 percent in the same period in 2011. Excluding acquisition costs of $2.5 million, total SG&A expenses as a percentage of revenues was 25.5 percent for the three months ended March 31, 2012.

Interest Expense and Interest Income

Interest expense was $0.7 million for the three months ended March 31, 2012 and 2011.  

Provision for Income Taxes

The provision for income taxes was $3.9 million for the three months ended March 31, 2012 compared with $2.5 million for the same period in the prior year. The annual effective tax rate was 41.8 percent for the three months ended March 31, 2012 and 44.4 percent for the same period in 2011.  The decrease in the tax rate in 2012 was primarily related to the year-over-year increase in forecasted income before income taxes for 2012. While permanent differences are estimated to increase in 2012, they will not increase as much as income before income taxes, which lowered the estimated annual effective rate.

Liquidity and Capital Resources

Our working capital as of March 31, 2012 was $75.8 million and our cash and cash equivalents were $17.7 million, of which $8.4 million was held in foreign countries. Cash held in foreign countries is not available to fund domestic operations unless repatriated, which would require the accrual and payment of taxes. We do not intend to repatriate cash held in foreign countries. Our operating cash flows have been our primary source of liquidity and historically have been sufficient to fund our working capital and capital expenditure needs. Our working capital requirements consist primarily of the financing of accounts receivable, payroll expenses and the periodic payments of principal and interest on our loans.

Net cash provided by operating activities was $7.0 million for the three months ended March 31, 2012 compared with $5.8 million in the same period in 2011.  This increase was primarily due to an increase in net operating income and changes in operating assets and liabilities. The increase is partially offset by the receipt of tenant improvement allowances from the landlord of our new corporate headquarters in 2011 that did not recur in 2012.

Net cash used in investing activities was $2.1 million in three months ended March 31, 2012 compared with $19.2 million in the same period in 2011.  For the three months ended March 31, 2012, we did not have any acquisitions. Capital expenditures for information technology projects, leasehold improvements and various property and equipment purchases were $2.1 million. We estimate that capital expenditures for the full year 2012 will be approximately $8.0 million.

Net cash used in financing activities was $5.2 million for the three months ended March 31, 2012, compared with net cash provided by financing activities of $11.5 million for the same period in 2011. In 2012, the net cash used in financing activities related to $6.3 million in payments on long-term debt, offset by stock related transactions. In 2011, we received $11.8 million in net proceeds from our debt facilities, the proceeds were primarily to fund the acquisition of Valesta.

Under terms of the credit facility, the term loan facility is repayable at the minimum rate of $1.3 million per quarter and we are required to reduce the term loan by up to 50 percent of our excess cash flow based on leverage ratios, as defined by the agreement, for each year end over the next five years. We are required to maintain certain financial covenants, including a maximum leverage ratio and a minimum fixed charge coverage ratio. As of March 31, 2012, we were in compliance with all such covenants. Additionally, the agreement, which is secured by substantially all of our assets, provides for certain limitations on our ability to, among other things, incur additional debt, offer loans, declare dividends and incur capital expenditures.

We continue to make progress on enhancements to our front-office and back-office information systems.  These enhancements include the consolidation of back-office systems across all corporate functions, as well as enhancements to and broader application of our front-office software across all lines of business.

We believe that our working capital as of March 31, 2012, our credit facility and our positive operating cash flows expected from future activities will be sufficient to fund future requirements of our debt obligations, accounts payable and related payroll expenses as well as capital expenditure initiatives for the next twelve months. If the Merger is approved, the Company will have additional capital commitments, which will be funded by the debt financing. See Apex Systems, Inc. Merger Agreement above for further information.

Recent Accounting Pronouncements

See Note 2, Accounting Standards Updates, to the Condensed Consolidated Financial Statements in Part I, Item I of this report for a discussion of new accounting pronouncements.

Critical Accounting Policies

There have been no significant changes to our critical accounting policies and estimates during the quarter ended March 31, 2012 compared with those disclosed in Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations of our Annual Report on Form 10-K for the year ended December 31, 2011, as filed with the SEC on March 14, 2012.

Commitments

As described above and in our Proxy Statement, filed with the SEC on April 13, 2012, we entered into an Agreement of Merger on March 20, 2012 to acquire Apex Systems, Inc. for a combination of $217 million of On Assignment common stock and $383 million in cash, subject to adjustment in certain circumstances. Under the Agreement of Merger, we will be required to pay a termination fee of $21.0 million to Apex Systems, Inc. if the transaction does not close under certain circumstances as outlined in the Agreement of Merger.

17

In connection with acquisitions, we are subject to earn-out obligations. If the acquired businesses meet predetermined targets, we are obligated to make additional cash payments in accordance with the terms of such earn-out obligations. As of March 31, 2012, the Company has potential future earn-out obligations of approximately $10.4 million through 2013.

Other than those described above, we have not entered into any significant commitments or contractual obligations that have not been previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2011, as filed with the SEC on March 14, 2012.

Item 3 – Quantitative and Qualitative Disclosures about Market Risk

There have been no material changes to the information included in our Annual Report on Form 10-K for the year ended December 31, 2011.  We are exposed to certain market risks arising from transactions in the normal course of business, principally risks associated with foreign currency fluctuations and changes in interest rates. We are exposed to foreign currency risk from the translation of foreign operations into U.S. dollars. Based on the relative size and nature of our foreign operations, we do not believe that a ten percent change in the value of foreign currencies relative to the U.S. dollar would have a material impact on our financial statements. Our primary exposure to market risk is interest rate risk associated with our debt instruments. See “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations” for further description of our debt instruments. Excluding the effect of our interest rate swap agreement, a hypothetical 1.0 percent change in interest rates on variable rate debt would have resulted in interest expense fluctuating approximately $0.8 million based on $80.5 million of debt outstanding for any twelve month period. Including the effect of our interest rate swap agreement, a 1.0 percent change in interest rates on variable debt would have resulted in interest expense fluctuating approximately $0.6 million based on $80.5 million of debt outstanding for any twelve month period. We have not entered into any market risk sensitive instruments for trading purposes

Item 4 – Controls and Procedures

As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Principal Financial and Accounting Officer, of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934). Based on this evaluation, our Chief Executive Officer and Principal Financial and Accounting Officer have concluded that our disclosure controls and procedures are effective as of the end of the period covered by this report.  The term “disclosure controls and procedures” means controls and other procedures of the Company that are designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within required time periods.  We have established disclosure controls and procedures to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Securities Exchange Act of 1934 is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

There have been no changes in our internal control over financial reporting that occurred during the quarter ended March 31, 2012 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1 – Legal Proceedings

The information set forth above under Note 9, Commitments and Contingencies, contained in the Notes to Condensed Consolidated Financial Statements in Part I, Item 1 of this report is incorporated herein by reference.

Item 1A – Risk Factors

Information regarding risk factors affecting our business is discussed in our Annual Report on Form 10-K for the year ended December 31, 2011. Based on the proposed acquisition of Apex Systems, Inc., we have included the following additional risk factors:

Failure to complete the Merger could negatively affect our stock price and future business and operations.

There is no assurance that the Merger or any other transaction contemplated under the Merger Agreement will occur or that the conditions to the Merger will be satisfied or waived in a timely manner or at all.  To complete the Merger, our shareholders must approve the issuance of shares of On Assignment’s common stock as contemplated by the Merger Agreement. In addition, the Merger Agreement contains certain other closing conditions, each of which may not be satisfied or waived.  If the Merger is not completed for any reason, we may be subject to a number of risks, including the following:

·  We will not realize the benefits expected from the Merger, including a potentially enhanced financial and competitive position;

·  The current market price of our common stock may reflect a market assumption that the Merger will occur and a failure to complete the Merger could result in a negative perception of us by the stock market and a resulting decline in the market price of our common stock; and

·  Many of the costs relating to the Merger, including certain investment banking, financing, legal and accounting fees and expenses, must be paid even if the Merger is not completed, and we may be required to pay a termination fee of $21.0 million to Apex if the Merger Agreement is terminated under certain circumstances.

The occurrence of any of these events individually or in combination could have a material adverse effect on our results of operations or on the trading price of our common stock.

If the Merger is completed, we will incur substantial indebtness and there is no assurance that we will successfully integrate the Apex Systems, Inc. business.

In the event that the Merger is completed, the acquisition of Apex Systems, Inc. represents a significant investment by On Assignment. Although it is our intent that Apex will continue to operate substantially as it has in the past and the existing senior management team will remain in place, it will require significant attention and resources of other On Assignment personnel which could reduce the likelihood of achievement of our other corporate goals. There is no assurance that we will, on a sustainable basis, successfully integrate any or all of the various aspects to the acquired business. Failure to smoothly and successfully integrate the Apex business could lead to a reduction in our overall revenues, and therefore could have a material adverse effect on our results of operations or on the trading price of our common stock.Additionally, the Merger, if completed, will be financed with additional senior debt financing in the aggregate principal amount of $540.0 million. This debt, or additional debt that may be incurred with any other future acquisitions, could adversely affect our profitability and limit our ability to capitalize on future business opportunities.

Item 2 – Unregistered Sales of Equity Securities and Use of Proceeds

There were no purchases of equity securities during the quarter ended March 31, 2012.

Item 3 – Defaults Upon Senior Securities

None.

Item 4 – Mine Safety Disclosures

“Notwithstanding the foregoing, payment or settlement of Additional Grants, if applicable, may be accelerated as provided in Section 1(b)(iii)(E) and (F) below.  Subject to the foregoing requirements, Additional Grants shall be made under a Plan and shall be paid at the time of settlement, to the extent earned, in either (i) fully vested, freely transferable shares of Company common stock (subject to limitations on transfer imposed under applicable law) or (ii) if insufficient shares remain under the applicable Plan at the time of settlement to pay any earned portion of an Additional Grant in shares of Company common stock, then such portion of the Additional Grant shall instead be paid in cash.  During the first ninety days of the calendar year in which such Additional Grant is made (and, in any event, upon or prior to making the applicable grant), the Company and Executive shall determine by mutual agreement the performance criteria applicable to the vesting of Additional Grants (selected from performance criteria enumerated in a Plan) and the Compensation Committee shall, in consultation with Executive, establish in writing performance goals applicable to each Additional Grant based on such performance criteria and determined by reference to the thirteen-month performance period beginning on January 1 of the year of grant, provided, that (a) with respect to the 2010 Additional Grant only, the relevant performance period shall instead commence on January 1, 2010 and shall continue through December 31, 2012, (b) with respect to the two Additional Grants made during calendar year 2011 (the “2011 Additional Grants”) only, the relevant performance period shall instead commence on January 1, 2011 and shall continue through December 31, 2011 and (c) with respect to the three Additional Grants made during calendar year 2012 (the “2012 Additional Grants”) only, the relevant performance period shall instead commence on January 1, 2012 and shall continue through December 31, 2012.  Each Additional Grant shall vest, subject to Sections 1(b)(iii)(E) and (F) below, on February 1 of the year immediately following the year in which such Additional Grant is made, subject to Executive’s continued employment through such February 1, in each case, as to (i) no portion of the award if the applicable performance goals are attained at less than 90% of target, (ii) 80% of the award if the applicable performance goals are attained at 90% of target, (iii) 100% of the award if the applicable performance goals are attained at or above 110% of target, and (iv) a linear pro ration between 80% – 100% of the award if the applicable performance goals are attained between 90% – 110% of target (for example, an Additional Grant shall vest as to 95% of the award upon attainment of 105% of the applicable target), provided, that subject to each of Sections 1(b)(iii)(E) and (F) below, (x) the continued service requirement applicable to the 2010 Additional Grant shall be satisfied by Executive’s continued employment through February 1, 2011, but vesting of the award shall remain subject to the attainment of the applicable performance criteria during the applicable performance period (to the extent not previously attained), (y) the continued service requirement applicable to the 2011 Additional Grants shall be satisfied by Executive’s continued employment through January 1, 2012, but vesting of the award shall remain subject to the attainment of the applicable performance criteria during the applicable performance period (to the extent not previously attained) and (z) the continued service requirement applicable to the 2012 Additional Grants shall be satisfied by Executive’s continued employment through January 1, 2013, but vesting of the award shall remain subject to the attainment of the applicable performance criteria during the applicable performance period (to the extent not previously attained).”

2.   Section 1(b)(iii)(F)(1)(c) of the Employment Agreement is deleted and replaced in its entirety by the following:

“(c)           Additional Grants.  Additional Grants that have vested but have not been settled or paid as of the date of a Qualifying Termination shall be settled or paid as soon as practicable after the February 1 immediately following the Date of Termination, but in no event later than the March 15 immediately following such Date of Termination.  Additional Grants, other than the 2010 Additional Grant, the 2011 Additional Grants and the 2012 Additional Grants, that have not vested as of the Date of Termination shall remain outstanding and eligible to vest upon the February 1 immediately following the Date of Termination (without the requirement of continued employment beyond such termination) and shall vest on a pro-rated basis upon and be paid as soon as practicable after such February 1 (but in no event later than the March 15 immediately following such Date of Termination), in a manner determined by multiplying amounts that would be earned under such Additional Grant based solely on attainment of the applicable performance objectives by a fraction, the numerator of which equals the number of days Executive was employed by the Company from January 1 of the applicable year of grant through the Date of Termination, and the denominator of which equals 396.  With respect to the 2010 Additional Grant, (i) if a Qualifying Termination occurs prior to February 1, 2011, the 2010 Award shall be treated in accordance with the immediately preceding sentence (with attainment of the performance objectives measured through February 1, 2011), and (ii) if a Qualifying Termination occurs on or after February 1, 2011 (but prior to February 1, 2013), the 2010 Additional Award shall be settled or paid based on actual performance through the Date of Termination, subject to Section 1(g) below, as soon as practicable after the February 1 immediately following the Date of Termination, but in no event later than the March 15 immediately following the Date of Termination.  The 2011 Additional Grants and the 2012 Additional Grants that have not vested as of the Date of Termination shall remain outstanding and eligible to vest upon the January 1 immediately following the Date of Termination (without the requirement of continued employment beyond such termination) and shall vest on a pro-rated basis upon and be paid as soon as practicable after such January 1 (but in no event later than the March 15 immediately following such Date of Termination), in a manner determined by multiplying amounts that would be earned under the 2011 Additional Grants or the 2012 Additional Grants, as applicable, based solely on attainment of the applicable performance objectives by a fraction, the numerator of which equals the number of days Executive was employed by the Company from January 1 of the applicable year of grant through the Date of Termination, and the denominator of which equals 365.”

2

3.   Section 1(b)(iii)(F)(4) of the Employment Agreement is deleted and replaced in its entirety by the following:

“(4)           Forfeiture of Awards.  All LTIP Awards that have not vested (a) in the case of a termination of Executive’s employment for Cause or due to Executive’s resignation other than for Good Reason, as of the Date of Termination, shall terminate as of the Date of Termination, (b) with respect to LTIP Awards, other than PEA Grants and ETA Grants made during calendar years 2011 and 2012, the 2011 Additional Grants and the 2012 Additional Grants, in the case of a Qualifying Termination in which such LTIP Awards remain unvested as of the February 1 following the Date of Termination (after taking into consideration any vesting that may occur upon or following the Date of Termination as provided above or under any other agreement between Executive and Company), shall terminate as of such February 1, and, in all cases, shall be canceled without payment of consideration therefor, and (c) with respect to PEA Grants and ETA Grants made during calendar years 2011 and 2012, the 2011 Additional Grants and the 2012 Additional Grants, in the case of a Qualifying Termination in which such LTIP Awards remain unvested as of the January 1 following the Date of Termination (after taking into consideration any vesting that may occur upon or following the Date of Termination as provided above or under any other agreement between Executive and Company), shall terminate as of such January 1, and, in all cases, shall be canceled without payment of consideration therefor.  Following settlement or payment of any vested LTIP Awards, if applicable, such awards shall terminate and Executive shall have no further rights or interests in respect of such awards.”

NOW, THEREFORE, in consideration of the foregoing premises and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

1.Amendment of Section 9 of Security Agreement Regarding Government Accounts.   Clause (i) of Section 9 of the Security Agreement is hereby amended and restated in its entirety to read as follows:

1

“(i)                   in the event that, at any time, the Grantors (x) have accounts (“Government Accounts”) owing from account debtors that are agencies, departments or instrumentalities of the United States or any state thereof (“Government Debtors”), and (y) the aggregate amount owing to the Grantors under all Government Accounts is in excess of 10% (the “Threshold Amount”) of the aggregate amount owing to the Grantors by all account debtors of all the Grantors, then within 90 days thereafter the Grantors shall satisfy the requirements of the Assignment of Claims Act of 1940 and any similar state legislation with respect to sufficient Government Accounts so that the aggregate amount of Government Accounts owing from Government Debtors with respect to which the requirements for the Administrative Agent to have a perfected security interest does not exceed the Threshold Amount and the Grantors shall continue to so satisfy the Assignment of Claims Act of 1940 with respect to all Government Accounts of the Grantors until such time as the Borrower has delivered to the Administrative Agent a Compliance Certificate pursuant to Section 6.02(b) of the Credit Agreement certifying that the amount of Government Accounts no longer exceeds the Threshold Amount; provided, however, that if the amount of Government Accounts exceeds the Threshold Amount at any time during the continuance of an Event of Default, then upon the written request from the Administrative Agent during such Event of Default, the Grantors shall, within 45 days thereafter, satisfy the requirements of the Assignment of Claims Act and any similar state legislation with respect to all Government Accounts so that the Administrative Agent shall have a perfected security interest in all Government Accounts, and the Grantors shall continue to so satisfy the Assignment of Claims Act of 1940 and such state legislation until such time as the Event of Default has been cured or waived.”

2.Waiver.

a.Clause (i) of Section 9 of the Security Agreement as in effect prior to the date hereof defined the Threshold Amount set forth above to be 5%.  The amount of Government Accounts as of December 31, 2011 was in excess of 5% but below 10%,  and you have requested that the Administrative Agent and the Lenders waive the restrictions contained in such clause for such period provided that the total amount of Government Receivables did not exceed the Threshold Amount as revised pursuant to this Amendment No. 2.

Acquisitions [Abstract]

Acquisitions

3.Acquisitions.On March 20, 2012, On Assignment entered into an Agreement of Merger (the Merger Agreement) with Apex Systems, Inc., a Virginia corporation (Apex), OA Acquisition Corp., a Virginia corporation (Merger Sub), and Jeffrey E. Veatch as the Shareholder Representative. Pursuant to the Merger Agreement, the Merger Sub will merge with and into Apex (the Merger), with Apex continuing as the surviving entity. As a result of the Merger, Apex will become a wholly owned subsidiary of On Assignment. As more fully described in our Proxy Statement, filed with the SEC on April 13, 2012, and in the Merger Agreement, under the Merger Agreement the aggregate consideration to be received by Apex shareholders is $217 million of On Assignment common stock and $383 million in cash, subject to adjustment in certain circumstances. The obligation of On Assignment and Merger Sub to complete the Merger is subject to the satisfaction or waiver of a number of conditions set forth in the Merger Agreement, including the approval by On Assignment's shareholders of the issuance of common stock to Apex shareholders in the Merger, the receipt of proceeds by On Assignment of debt financing in the aggregate principal amount of $540 million and other customary closing conditions.  In connection with the execution of the Merger Agreement, On Assignment obtained a commitment for a new $540 million senior secured credit facility. The credit facility provides for a $75 million revolving credit facility, $100 million term loan A and $365 million term loan B. The proceeds of the credit facility, which are to be funded in connection with the completion of the Merger, will be used to finance the cash portion of the purchase price, to repay existing indebtedness of On Assignment and Apex Systems and to pay fees and expenses in connection with the transaction. The Merger is expected to close during the second quarter of 2012. The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, a copy of which is attached to the Current Report on Form 8-K filed on March 26, 2012.

On February 28, 2011, the Company acquired all of the outstanding shares of Valesta, a privately-owned provider of specialized clinical research staffing headquartered in Belgium. The primary reasons for the acquisition were to expand the Life Sciences business operations and to leverage the Company's infrastructure. The purchase price for Valesta totaled $23.7 million comprised of $16.8 million in cash paid at closing, plus potential future earn-out consideration of $6.9 million (the maximum earn-out is capped at a Euro value of 5.0 million or approximately $6.7 million at March 31, 2012 exchange rates) based on estimated financial performance of Valesta through 2013. Acquisition costs related to this transaction totaled approximately $0.4 million and were expensed in 2011. Goodwill is not deductible for tax purposes. The results of operations for the acquisition have been combined with those of the Company since the acquisition date.

On July 31, 2011, the Company acquired all of the outstanding shares of HealthCare Partners (HCP), a privately-owned provider of physician staffing headquartered in Atlanta, Georgia. The primary reasons for the acquisition were to expand the Physician segment business operations geographic coverage and to leverage the Company's infrastructure. The estimated purchase price for HCP was approximately $19.1 million comprised of $15.7 million in cash paid at closing, plus potential future earn-out consideration of $3.4 million (the maximum earn-out is capped at $3.7 million) based on estimated financial performance of HCP through 2013. Acquisition costs related to this transaction totaled approximately $57,000 and were expensed in 2011. Goodwill is deductible for tax purposes. The results of operations for the acquisition have been combined with those of the Company since the acquisition date.

 Assets and liabilities of the acquired companies were recorded at their estimated fair values at the dates of acquisition. The excess purchase price over the fair value of net tangible assets and identifiable intangible assets acquired has been allocated to goodwill. The fair value assigned to identifiable intangible assets was determined primarily by using a discounted cash flow method. The Company intends to discontinue the use of the HCP tradename during 2012. The Company's allocation of the purchase price for HCP is preliminary, as the amounts related to working capital and income taxes are still being finalized. Any measurement period adjustments will be recorded retrospectively to the acquisition date. During the quarter ended March 31, 2012, the Company adjusted Valesta's purchase price allocation. The adjustment was to recognize the tax impact of the amortization of identifiable intangible assets. The adjustment was not material and had no impact on the consolidated statement of operations; accordingly it is not presented retrospectively.

The fair value of earn-out obligations is based on the present value of the expected future payments to be made to the sellers of the acquired businesses in accordance with the respective purchase agreements. See Note 6 for further information regarding the fair value of earn-outs and the level 3 rollforward disclosure.

The following table summarizes (in thousands) the purchase price allocation for the acquisitions of HCP, which is subject to finalization during the measurement period and Valesta:

	2011 Acquisitions
	HCP		Valesta		Total
Current assets	$	3,941	$	6,332	$	10,273

The pro forma financial information gives effect to certain adjustments, including: the amortization of intangible assets and interest expense on acquisition-related debt and changes in the management fees as a result of the acquisition. Acquisition-related costs are assumed to have occurred at the beginning of the year prior to acquisition.

Accounting Standards Updates

2. Accounting Standards Updates.  

In December 2011, the Financial Accounting Standards Board (FASB) issued FASB Accounting Standards Update (ASU) No. 2011-11, Balance Sheet (Topic 210)-Disclosures about Offsetting Assets and Liabilities. ASU 2011-11 requires an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position. Entities are required to disclose both gross and net information about these instruments. ASU 2011-11 is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The adoption of this ASU is not expected to have a material impact on the Company's consolidated financial statements.

In September 2011, the FASB issued ASU No. 2011-08, Testing Goodwill for Impairment (Topic 350) - Intangibles-Goodwill and Other (ASU 2011-08), to allow entities to use a qualitative approach to test goodwill for impairment. ASU 2011-08 permits an entity to first perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If so, it is necessary to perform the currently prescribed two-step goodwill impairment test. Otherwise, the two step goodwill impairment test is not required. ASU 2011-08 is effective for the Company in the first quarter of fiscal 2012 and earlier adoption is permitted. The adoption of ASU 2011-08 did not have a material impact on the consolidated financial statements.

In June 2011, the FASB issued ASU No. 2011-05, Presentation of Comprehensive Income (Topic 220) - Comprehensive Income (ASU 2011-05), to require an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. ASU 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of equity. ASU 2011-05 is effective for the Company in the first quarter of fiscal 2012 and should be applied retrospectively. In December 2011, the FASB issued ASU 2011-12, Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05, which defers certain aspects of ASU 2011-05 related to the presentation of reclassification adjustments. The adoption of ASU 2011-05 only impacted the presentation of the consolidated financial statements.

In May 2011, the FASB issued ASU No. 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S.GAAP and International Financial Reporting Standards (Topic 820) - Fair Value Measurement (ASU 2011-04), to provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are similar between U.S. Generally Accepted Accounting Principles and International Financial Reporting Standards. ASU 2011-04 changes certain fair value measurement principles and enhances the disclosure requirements particularly for Level 3 fair value measurements. ASU 2011-04 became effective for the Company in the first quarter of fiscal 2012; see Note 6 for required disclosures.

Fair Value of Financial Instruments

Fair Value Of Financial Instruments [Abstract]

Fair Value of Financial Instruments

6.Fair Value Measurements.  The valuation techniques utilized are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect internal market assumptions. These two types of inputs create the following fair value hierarchy:

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

Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data.

Level 3: Unobservable inputs that are not corroborated by market data.

 The recorded values of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate their fair value based on their short-term nature. Long-term debt recorded in the Company's Condensed Consolidated Balance Sheets at March 31, 2012 was $80.5 million. The fair value of the long-term debt was determined using the quoted price technique, based on Level 2 inputs including the yields of comparable companies with similar credit characteristics, was $78.5 million.

The interest rate swap liability is measured using the income approach. The fair value reflects the estimated amounts that the Company would pay or receive based on the present value of the expected cash flows derived from market rates and prices.  As such, this derivative instrument is classified within Level 2.  

The Company has obligations, to be paid in cash, to the former owners of acquired companies if certain future financial goals are met.  The fair value of this contingent consideration is determined using an expected present value technique.  Expected cash flows are determined using the probability - weighted average of possible outcomes that would occur should certain financial metrics be reached.  There is no market data available to use in valuing the contingent consideration, therefore, the Company developed its own assumptions related to the future financial performance of the businesses to evaluate the fair value of these liabilities.  As such, the contingent consideration is classified within Level 3.  

In connection with estimating the fair value of the contingent consideration, the Company develops various scenarios (base case, downside case, and upside case) and weights each according to the probability of occurrence. The probabilities range from 5 percent to 85 percent, with the most significant weighting given to the base case at 80-85 percent. These scenarios are developed based on the expected financial performance of the acquired companies, with revenue growth rates being a primary input to the calculation. These revenue growth rates range from 1.0 percent to 29.4 percent. An increase or decrease in the probability of achievement of any of these scenarios could result in a significant increase or decrease to the estimated fair value. 

The fair value is reviewed on a quarterly basis based on most recent financial performance of the most recent fiscal quarter. An analysis is performed at the end of each fiscal quarter to compare actual results to forecasted financial performance. If performance has deviated from projected levels, the valuation is updated for the latest information available.

The significant assumptions that may materially affect the fair value are developed in conjunction with the guidance of the division presidents, division vice presidents, and chief financial officer to ensure that the most accurate and latest financial projections are used and compared with the most recent financial results in the fair value measurement.

The liabilities for the contingent consideration were established at the time of the acquisition and are evaluated at each reporting period.  The current liability is included in the Condensed Consolidated Balance Sheets in the current portion of accrued earn-outs and the non-current portion is included in accrued earn-outs. Fair value adjustments are included in the Condensed Consolidated Statements of Operations and Comprehensive Income in selling, general and administrative expenses.

Certain assets and liabilities, such as goodwill, are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (e.g., when there is evidence of impairment).  For the three months ended March 31, 2012, no fair value adjustments were required for non-financial assets or liabilities.

Earnings per share

10.Earnings per share.Basic earnings per share are computed based upon the weighted average number of common shares outstanding. Diluted earnings per share are computed based upon the weighted average number of common shares outstanding and dilutive common share equivalents (consisting of incentive stock options, non-qualified stock options, restricted stock awards and units and employee stock purchase plan shares) outstanding during the periods using the treasury stock method.

The following is a reconciliation of the shares used to compute basic and diluted earnings per share (in thousands):

The following table presents the weighted average share equivalents outstanding during each period that were excluded from the computation of diluted earnings per share because the exercise price for these options was greater than the average market price of the Company's shares of common stock during the respective periods that became anti-dilutive when applying the treasury stock method (in thousands):

Incentive Award Plan And Employee Stock Purchase Plan [Abstract]

Incentive Award Plan and Employee Stock Purchase Plan

8.Incentive Award Plan and Employee Stock Purchase Plan. The Company granted discrete stock-based awards to its Chief Executive Officer (CEO) as follows: (i) a market based award in 2010, which as of March 31, 2012 was valued at $0.5 million, which is the full value of the award based on the achievement of defined market targets. This award is expensed over a service period of 2.6 yearsand the number of shares will be determined by dividing $0.5 million by the closing price of the Company stock on February 1, 2013, (ii) a performance based award on March 8, 2011, which had a grant date fair market value of $1.0 million and was expensed over a service period of 9.9 months. The Company met the financial performance objectives during the twelve month period ending December 31, 2011 and the number of shares will be determined by dividing $0.5 million by the closing price of the Company's stock on each February 1, 2013 and February 1, 2014, and (iii) a performance based award on March 23, 2012, which had a grant date fair market value of $1.5 million. The number of shares will be determined by dividing $0.5 million by the closing price of the Company's stock on each of February 1, 2013, February 1, 2014 and February 1, 2015 contingent upon the Company meeting certain financial performance objectives measured over the twelve month period between January 1, 2012 and December 31, 2012. The Company classifies these awards as liability awards until the number of shares is determined. The liability of $1.4 million related to these awards is included in other accrued expenses and other long-term liabilities in the accompanying Condensed Consolidated Balance Sheets as of March 31, 2012.

On March 5, 2012, the CEO was awarded 45,372 RSUs with a grant date fair market value of $0.6 million, which will vest in two equal components of $0.3 million on January 1, 2013 and January 1, 2014, contingent upon the Company achieving certain performance objectives based on adjusted EBITDA (earnings before interest, taxes, depreciation, and amortization of identifiable intangible assets, "EBITDA", plus equity-based compensation expense, impairment charges and acquisition related costs)approved by the Compensation Committee over the twelve-month period ending December 31, 2012. On January 3, 2012, the CEO was awarded 72,596 RSUs with a grant date fair market value of $0.8 million, which will vest on January 1, 2013, based on the Company achieving positive EBITDA during the twelve month period ending December 31, 2012. The grant-date fair market value of the RSUs described in this paragraph is being expensed over the vesting term, based on an estimate of the percentage achievement of the applicable performance targets. All awards are subject to the CEO's continued employment through applicable vesting dates. All awards may vest on an accelerated basis in part or in full upon the occurrence of certain events.

In the first quarter of 2012, the Company granted awards to certain other executive officers with an aggregate grant-date fair value of $1.7 million. Of the $1.7 million, $0.9 million will vest in three annual increments subject to continued employment on each succeeding grant-date anniversary. The remaining $0.8 million will vest on January 3, 2013, subject to continued employment and the Company attaining certain performance objectives during 2012, as approved by the Compensation Committee. Compensation expense for the performance-based component of these awards is recognized over the vesting period, based on an estimate of the percentage achievement of the targets for these awards.

On March 31, 2012 the Company issued 108,164 shares of common stock under the On Assignment 2010 Employee Stock Purchase Plan (ESPP).  

Compensation expense charged to operations related to stock-based compensation, including the ESPP, was $1.2 million and $1.6 million for the three months ended March 31, 2012 and March 31, 2011, respectively. Stock -based compensation is included in the Condensed Consolidated Statements of Operations and Comprehensive Income in selling, general and administrative expenses.

9.Commitments and Contingencies.  The Company is partially self-insured for its workers' compensation liability and its medical malpractice liability. The Company accounts for claims incurred but not reported based on estimates derived from historical claims experience and current trends of industry data. Changes or differences in estimates and actual payments for claims are recognized in the period that the estimates changed or the payments were made. The self-insurance claim liability was approximately $10.2 million and $10.4 million as of March 31, 2012 and December 31, 2011, respectively. Additionally, the Company has letters of credit outstanding to secure obligations for workers' compensation claims with various insurance carriers. The letters of credit outstanding were $2.4 million as of March 31, 2012 and December 31, 2011.

The Company is involved in various legal proceedings, claims and litigation arising in the ordinary course of business. Based on the facts currently available, the Company does not believe that the disposition of matters that are pending or asserted will have a material effect on its financial position, results of operations or cash flows.

As described in Note 3 and in the Proxy Statement, filed with the SEC onApril 13, 2012, the Company entered into an Agreement of Merger on March 20, 2012 to acquire Apex Systems, Inc. for a combination of $217 million of Company Common stock and $383 million in cash, subject to adjustment in certain circumstances.

Income Taxes [Abstract]

Income Taxes

11. Income Taxes. For interim reporting periods, the Company prepares an estimate of the full-year income and the related income tax expense for each jurisdiction in which the Company operates.  Changes in the geographical mix, permanent differences or estimated level of annual pretax income can impact the Company's actual effective rate.

As of March 31, 2012 and December 31, 2011, the estimated value of the Company's uncertain tax positions is a liability of $0.2 million, which includes penalties and interest, all of which is included in other long-term liabilities.  If the Company's positions are sustained by the taxing authority in favor of the Company, the entire $0.2 million would reduce the Company's effective tax rate. The Company recognizes accrued interest and penalties related to uncertain tax positions in income tax expense.

The Company is subject to taxation in the United States and various states and foreign jurisdictions. The Internal Revenue Service (IRS) has examined and concluded all tax matters for years through 2006.  The IRS has commenced an examination of the Company's U.S. income tax returns for the 2009 tax year. Open tax years related to federal, state and foreign jurisdictions remain subject to examination but are not considered material.

Derivative Instruments [Abstract]

Derivative Instruments

5.Derivative Instruments.  The Company utilizes derivative financial instruments to manage interest rate risk. The Company does not use derivative financial instruments for trading or speculative purposes, nor does it use leveraged financial instruments. The Company reports its derivative instruments separately as assets and liabilities unless a legal right of set-off exists under a master netting agreement enforceable by law. The Company's derivative instruments are recorded at their fair value, and are included in other long-term liabilities and other liabilities in the Condensed Consolidated Balance Sheets.

On February 18, 2011, the Company entered into an interest rate swap agreement to hedge a portion of its interest rate exposure on its senior secured debt (the 2011 Interest Rate Swap). The 2011 Interest Rate Swap has a notional amount of $25.0 million and fixes a portion of the Company's base borrowing rate, which is a floating rate based on a LIBOR swap rate that resets periodically.  The 2011 Interest Rate Swap was designated as a hedging instrument for accounting purposes and is accordingly accounted for as a cash flow hedge. The effective portion of unrealized losses on this interest rate swap agreement are included in accumulated other comprehensive income until the periodic interest settlements occur, at which time they will be recorded as interest expense in the Consolidated Statements of Operations and Comprehensive Income. The Company expects to reclassify losses of $0.3 million (pretax) from Accumulated Other Comprehensive Income to interest expense in the Consolidated Statements of Operation within the next twelve months.

As a result of the use of derivative instruments, the Company is exposed to risk that the counterparties will fail to meet their contractual obligations. To mitigate the counterparty credit risk, the Company only enters into contracts with carefully selected major financial institutions based upon their credit ratings and other factors, and continually assess the creditworthiness of counterparties. As of March 31, 2012, the counterparty to the interest rate swap had investment grade ratings and has performed in accordance with their contractual obligations.
