NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

The information in this Quarterly Report on Form 10-Q includes the financial position of InfuSystem Holdings, Inc. and its consolidated subsidiaries (the “Company”) as of March 31, 2011 and December 31, 2010, the results of operations and cash flows for the three months ended March 31, 2011 and 2010. In the opinion of the Company, the consolidated statements for the all periods presented include all adjustments, consisting of normal recurring adjustments, necessary to present a fair statement of the results for such periods. The accompanying unaudited financial statements should be read in conjunction with the December 31, 2010 annual report 10-K.

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). All intercompany accounts and transactions have been eliminated. Results of operations for the three months ended March 31, 2011 are not necessarily indicative of the results for an entire year.

The Company is the leading provider of infusion pumps and related services. The Company services hospitals, oncology practices and other alternate site healthcare providers. Headquartered in Madison Heights, Michigan, the Company delivers local, field-based customer support, and also operates pump repair Centers of Excellence in Michigan, Kansas, California, and Ontario, Canada.

On June 15, 2010, the Company entered into a stock purchase agreement with the shareholders of First Biomedical, Inc., (First Biomedical) a Kansas corporation, to acquire all of the issued and outstanding stock of First Biomedical and completed the acquisition simultaneously. First Biomedical sells, rents, services and repairs new and pre-owned infusion pumps and other medical equipment. First Biomedical also sells a variety of primary and secondary tubing, cassettes, catheters and other disposable items that are utilized with infusion pumps. For more information, refer to the “Acquisition” discussion included in Note 3.

The Company supplies electronic ambulatory infusion pumps and associated disposable supply kits to oncology practices, infusion clinics and hospital outpatient chemotherapy clinics. These pumps and supplies are utilized primarily by colorectal cancer patients who receive a standard of care treatment that utilizes continuous chemotherapy infusions delivered via electronic ambulatory infusion pumps. The Company obtains an assignment of insurance benefits from the patient, bills the insurance company or patient accordingly, and collects payment. The Company provides pump management services for the pumps and associated disposable supply kits to over 1,300 oncology practices in the United States. The Company retains title to the pumps during this process.

In addition, the Company sells or rents new and pre-owned pole mounted and ambulatory infusion pumps to, and provides biomedical recertification, maintenance and repair services for oncology practices as well as other alternate site settings including home care and home infusion providers, skilled nursing facilities, pain centers and others. The Company also provides these products and services to customers in the small-hospital market.

The Company purchases new and pre-owned pole mounted and ambulatory infusion pumps from a variety of sources on a non-exclusive basis. The Company repairs, refurbishes and provides biomedical certification for the devices as needed. The pumps are then available for sale, rental or to be used within the Company’s ambulatory infusion pump management service.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and all wholly owned organizations. All intercompany transactions and account balances have been eliminated in consolidation.

Segments

The Company operates in one business segment based on management’s view of its business for purposes of evaluating performance and making operating decisions, representing the only reportable segment in accordance with Accounting Standard Codification (“ASC”) 280, “Segment Reporting.”

The Company utilizes shared services including but not limited to, human resources, payroll, finance, sales, pump repair and maintenance services, as well as certain shared assets and sales, general and administrative costs. The Company is in the process of transitioning more shared services and synergies since the acquisition of First Biomedical. The Company’s approach is to make operational decisions and assess performance based on delivering products and services that together provide solutions to our customer base, utilizing functional management structure and shared services where possible. Based upon this business model, the chief operating decision maker only reviews consolidated financial information.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates, assumptions and judgments that affect the amounts reported in the financial statements, including the notes thereto. The Company considers critical accounting policies to be those that require more significant judgments and estimates in the preparation of its consolidated financial statements, including the following: revenue recognition, which includes contractual adjustments; accounts receivable and allowance for doubtful accounts; sales return allowances; inventory reserves; income taxes; and goodwill valuation. Management relies on historical experience and other assumptions believed to be reasonable in making its judgment and estimates. Actual results could differ materially from those estimates.

Cash and Cash Equivalents

The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. The Company maintains its cash and cash equivalents primarily with two financial institutions and is fully insured with the Federal Deposit Insurance Corporation (FDIC) under the Temporary Liquidity Guarantee Program until December 31, 2012.

Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable are reported at the estimated net realizable amounts from patients, third-party payors and other direct pay customers for goods provided and services rendered. The Company performs periodic analyses to assess the accounts receivable balances. It records an allowance for doubtful accounts based on the estimated collectability of the accounts such that the recorded amounts reflect estimated net realizable value. Upon determination that an account is uncollectible, the account is written-off and charged to the allowance.

Accounts receivable are reduced by an allowance for amounts that could become uncollectible in the future. The Company’s estimate for its allowance for doubtful accounts is based upon management’s assessment of historical and expected net collections by payor. Due to continuing changes in the health care industry and third-party reimbursement it is possible that management’s estimates could change in the near term, which could have an impact on its financial position, results of operations, and cash flows.

Inventory

Our inventory consists of infusion pumps and related parts and supplies and is stated at the lower of cost, determined on a first in, first out basis, or market. The Company periodically performs an analysis of slow moving inventory and records a reserve based on estimated obsolete inventory.

Property and Equipment

Property and equipment is stated at acquired cost and depreciated using the straight-line method over the estimated useful lives of the related assets, ranging from three to seven years. Rental equipment, consisting primarily of infusion pumps that the Company acquires from third-parties, is depreciated over five years. Information Technology (IT) software and hardware are depreciated over three years. Leasehold improvements are amortized using the straight-line method over the life of the asset or the remaining term of the lease, whichever is shorter. Maintenance and minor repairs are charged to operations as incurred. When assets are sold, or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and any gain or loss is recorded in the current period.

Long-Lived Assets

The Company accounts for the impairment and disposition of long-lived assets in accordance with ASC 360, “Property, Plant and Equipment.” This standard addresses financial accounting and reporting for the impairment of long-lived assets and for the disposal of long-lived assets. In accordance with this standard, long-lived assets to be held are reviewed for events or changes in circumstances, which indicate that their carrying value may not be recoverable. If an impairment indicator exists, the Company assesses the asset or asset group for recoverability. Recoverability of these assets is determined based upon the expected undiscounted future net cash flows from the operations to which the assets relate, utilizing management’s best estimates, appropriate assumptions and projections at the time. If the carrying value is determined not to be recoverable from future operating cash flows, the asset is deemed impaired and an impairment loss would be recognized to the extent the carrying value exceeded the estimated fair market value of the asset. The Company reviews the carrying value of long-lived assets if there is an indicator of impairment. The Company has determined that no impairment indicators existed as of March 31, 2011.

Goodwill Valuation

Goodwill arising from business combinations represents the excess of the purchase price over the estimated fair value of the net assets of the businesses acquired.

In accordance with the provisions of ASC 350, “Intangibles – Goodwill and Other,” goodwill is tested annually for impairment or more frequently if circumstances indicate the possibility of impairment. Significant judgments required to estimate fair value include estimating future cash flows, and determining appropriate discount rates, growth rates and other assumptions. Changes in these estimates and assumptions could materially affect the determination of fair value which could trigger impairment. The Company performed the annual impairment test at October 31, 2010, and determined there was no impairment of goodwill. No events have occurred subsequent to October 31, 2010 that indicates impairment may have occurred. For more information, refer to the “Goodwill and Intangible Assets” discussion included in Note 5.

Intangible Assets

Intangible assets consist of trade names, physician and customer relationships, non-compete agreements, and software. The trade names, physician and customer relationships and non-compete agreements arose from the acquisitions of InfuSystem and First Biomedical. The Company amortizes the value assigned to the physician and customer relationships on a straight-line basis over the period of expected benefit, which is 15 years. The acquired physician and customer relationship base represents a valuable asset of InfuSystem due to the expectation of future business opportunities to be leveraged from the existing relationship with each physician and customer. InfuSystem has long-standing relationships with numerous oncology clinics, physicians, home care and home infusion providers, skilled nursing facilities, pain centers and others. These relationships are expected, on average, to have a 15 year useful life, based on minimal attrition experienced to date by the Company and expectations of continued minimal attrition. Non-compete agreements are amortized on a straight-line basis over five years and software is amortized on a straight-line basis over three years. Management tests non-amortizable intangible assets (i.e., trade names such as InfuSystem) for impairment in accordance with ASC 350. The Company performed the annual impairment test at October 31, 2010, and determined there was no impairment. No events have occurred subsequent to October 31, 2010 that indicates impairment may have occurred.

Accumulated Other Comprehensive Income (Loss)

Accumulated other comprehensive loss consists only of the unrealized loss on the single interest rate swap in place as of March 31, 2011, net of taxes. For more information on the interest rate swap, refer to Note 6. During the quarter there was a comprehensive gain of $67 thousand related to the unrealized gain on the swap. The tax impact on the gain was $20 thousand, leaving a net accumulated other comprehensive loss of $17 thousand. The following table summarizes comprehensive loss for the applicable periods (in thousands):

Revenue Recognition

The majority of the Company’s revenue is rental revenue in the oncology market. Revenues are recognized predominantly under fee for service arrangements through equipment that the Company rents to patients. The Company recognizes revenue only when all of the following criteria are met: 1) persuasive evidence of an arrangement exists; 2) services have been rendered; 3) the price to the customer is fixed or determinable; and 4) collectability is reasonably assured. Persuasive evidence of an arrangement is determined to exist, and collectability is reasonably assured, when the Company receives 1) a physician’s written order and assignment of benefits, signed by the physician and patient, respectively, and the Company has 2) verified actual pump usage and 3) insurance coverage. The Company recognizes rental revenue from electronic infusion pumps as earned, normally on a month-to-month basis. Pump rentals are billed at the Company’s established rates, which often differ from contractually allowable rates provided by third-party payors such as Medicare, Medicaid and commercial insurance carriers. All billings to third party payors are recorded net of provision for contractual adjustments to arrive at net revenues.

Table of Contents

Due to the nature of the industry and the reimbursement environment in which the Company operates, certain estimates are required to record net revenues and accounts receivable at their net realizable values. Inherent in these estimates is the risk that they will have to be revised or updated as additional information becomes available. Specifically, the complexity of many third-party billing arrangements and the uncertainty of reimbursement amounts for certain services from certain payors may result in adjustments to amounts originally recorded. Due to continuing changes in the health care industry and third-party reimbursement, it is possible that management’s estimates could change in the near term, which could have an impact on our results of operations and cash flows.

The Company’s largest payor is Medicare, which accounted for approximately 32% and 31% of its gross billings for the three months ended March 31, 2011 and 2010, respectively. The Company has contracts with various individual Blue Cross/Blue Shield affiliates which in the aggregate accounted for approximately 21% and 23% of its gross billings for the three months ended March 31, 2011 and 2010, respectively. No individual payor (other than Medicare and the Blue Cross/Blue Shield entities) accounts for greater than approximately 6% of the Company’s gross billings.

The Company recognizes revenue for selling, renting and servicing new and pre-owned infusion pumps and other medical equipment to oncology practices as well as other alternate site settings including home care and home infusion providers, skilled nursing facilities, pain centers and others, when persuasive evidence of an arrangement exists; services have been rendered; the price to the customer is fixed or determinable; and collectability is reasonably assured. The Company performs an analysis to estimate sales returns and records an allowance. This estimate is based on historical sales returns.

Income Taxes

The Company accounts for income taxes in accordance with ASC 740, “Income Taxes,” which requires that the Company recognize deferred tax liabilities and assets based on the differences between the financial statement carrying amounts and the tax basis of assets and liabilities, using enacted tax rates in effect in the years the differences are expected to reverse. Deferred income tax (expense) benefit results from the change in net deferred tax assets or deferred tax liabilities. A valuation allowance is recorded when, in the opinion of management, it is more likely than not that some or all of any deferred tax assets will not be realized. For more information, refer to the “Income Taxes” discussion included in Note 8.

Share Based Payment

ASC 718, “Stock Compensation,” requires all entities to recognize compensation expense in an amount equal to the fair value of share based payments made to employees, among other requirements. Under the fair value based method, compensation cost is measured at the grant date based on the fair value of the award and is recognized on a straight-line basis over the award vesting period. Accordingly, share based payments issued to officers and directors are measured at fair value and recognized as expense over the related vesting periods.

In 2007, the Company adopted the 2007 Stock Incentive Plan (the “Plan”) providing for the issuance of a maximum of 2,000,000 shares of common stock in connection with the grant of stock-based or stock-denominated awards. In addition, the Company has made certain grants of restricted stock outside of the Plan.

Share based compensation expense recognized for the three months ended March 31, 2011 was $248 thousand, compared to $100 thousand for the three months ended March 31, 2010.

Warrants and Derivative Financial Instruments

On April 18, 2006, the Company consummated its initial public offering (“IPO”) of 16,666,667 units. Each unit consists of one share of common stock and two redeemable common stock purchase warrants. Each warrant entitles the holder to purchase from the Company one share of its common stock at an exercise price of $5.00. On May 18, 2006, the Company sold an additional 208,584 units (the “Overallotment Units”) to FTN Midwest Securities Corp., the underwriter of its IPO (FTN Midwest), pursuant to a partial exercise by FTN Midwest of its overallotment option. The Warrant Agreement provides for the Company to register the shares underlying the warrants in the absence of the Company’s ability to deliver registered shares to the warrant holders upon warrant exercise.

ASC 815 requires freestanding derivative contracts that are settled in a company’s own stock, including common stock warrants, to be designated as equity instruments, assets or liabilities. Under the provisions of this standard, a contract designated as an asset or a liability must be carried at its fair value on a company’s balance sheet, with any changes in fair value recorded in the company’s results of operations. A contract designated as an equity instrument must be included within equity, and no fair value adjustments are required from period to period.

On February 16, 2010 the Company announced an Offer to Exchange common stock for outstanding warrants. At the time, the Company had 35,108,219 outstanding warrants. The exchange offer expired on March 17, 2010. Holders of the Company’s warrants

Table of Contents

had the option to exchange their warrants for either One (1) share of Common Stock for every thirty-five (35) Warrants tendered, or One (1) share of Common Stock for every twenty-five (25) Warrants tendered, provided the recipient agreed to be subject to a lock-up provision precluding transfer of the shares of Common Stock received for six months following the expiration of the Exchange Offer. The lock-up provision expired in September 2010. Based on the final count, 25,635,723 Warrants were properly tendered; 24,766,700 were tendered for shares of Common Stock subject to a lock-up, and 869,023 were tendered for unrestricted shares of Common Stock. Under the terms of the Exchange Offer, the Company issued an aggregate 1,015,489 shares of Common Stock in exchange for the tendered Warrants. After the exchange, there are 8,329,638 publicly held warrants and 1,142,858 privately held warrants outstanding. The Company recognized a loss of $491 thousand as a result of the exchange.

In accordance with ASC 815, the 8,329,638 remaining warrants issued in connection with the IPO and overallotment to purchase common stock must be settled in registered shares and are separately accounted for as liabilities as discussed in Note 6. The fair value of these warrants is shown on the Company’s balance sheet and the unrealized changes in the value of these warrants are shown in the Company’s statement of operations as “Gain (loss) on derivatives.” These warrants are freely traded on the “Over the Counter Bulletin Board.” Consequently, the fair value of these warrants is estimated as the market price of the warrant at each period end. To the extent the market price increases or decreases, the Company’s warrant liabilities will also increase or decrease with a corresponding impact on the Company’s results of operations within “Gain (loss) on derivatives”. As discussed in Note 10, the warrants expired on April 11, 2011.

Sales of warrants that can be settled in unregistered shares of common stock, as discussed in Note 10, are treated as equity and included in additional paid in capital. The total warrants issued to date that can be settled in unregistered shares of common stock are 1,142,858 at an issue price of $.70 per warrant or a total issue price of $800 thousand.

ASC 815 requires that an entity recognize all derivatives as either assets or liabilities in the statement of financial position and measure those instruments at fair value.

Cash Flow Hedge

The Company is exposed to risks associated with future cash flows related to the variability of the interest rate on its term loan with Bank of America. In order to manage the exposure of these risks, the Company enters into interest rate swaps. On July 20, 2010, the Company entered into a single interest rate swap and designated the swap as a cash flow hedge. In accordance with ASC 815, the fair value of the swap is shown on the Company’s consolidated balance sheet within derivative liabilities, unrealized changes in the fair value are included in accumulated other comprehensive loss within the stockholders’ equity section on the Company’s consolidated balance sheet, and any realized changes would be included in the Company’s consolidated statement of operations within interest expense.

Deferred Debt Issuance Costs

Capitalized debt issuance costs as of March 31, 2011 and December 31, 2010 relate solely to the Company’s Bank of America credit facility. The Company classifies the costs related to the Bank of America credit facility as non-current assets and amortizes them using the interest method through the maturity date of June 2014. For a further discussion of the Company’s deferred debt issuance costs, see Note 7.

Earnings Per Share

Basic loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted loss per share assumes the issuance of potentially dilutive shares of common stock during the period. The following table reconciles the numerators and denominators of the basic and diluted loss per share computations:

For the three months ended March 31, 2011 the following warrants and stock awards were not included in the calculation because they would have an anti-dilutive effect: 8,329,638 outstanding warrants issued in connection with the IPO, 1,142,858 warrants issued privately, 2,148,250 in non-vested restricted share grants, and 130,479 in vested stock options granted. For the three months ended March 31, 2010 the following warrants and stock awards were not included in the calculation because they would have an anti-dilutive effect: 8,329,638 outstanding warrants issued in connection with the IPO, 1,142,858 warrants issued privately, 298,000 in non-vested restricted share grants, and 130,479 in vested stock options.

Subsequent events

The Company adopted the provisions of ASC 855, “Subsequent Events” effective June 15, 2009 and management has concluded that there are no other significant subsequent events requiring disclosure as of the date the consolidated financial statements were issued other than the second and third amendments to the credit agreement as described in Note 7 and the expiration of the warrants in April 2011 as described in Note 10.

Entry into a Material Definitive Agreement

On June 15, 2010, the Company entered into a stock purchase agreement with the shareholders of First Biomedical, Inc., a Kansas corporation, (“First Biomedical”) to acquire all of the issued and outstanding stock of First Biomedical and completed the acquisition for total consideration of $17.4 million. Included in the consideration is $16.7 million paid in cash and a $750 thousand seller note described in further detail below.

First Biomedical sells, rents, services and repairs new and pre-owned infusion pumps and other medical equipment. First Biomedical also sells a variety of primary and secondary tubing, cassettes, catheters and other disposable items that are utilized with infusion pumps. Headquartered in Olathe, KS, with additional facilities in California and Toronto, First Biomedical is a leading provider to alternate site healthcare facilities and hospitals in the United States and Canada. The acquisition of First Biomedical allows the Company to expand its offerings to existing customers with the addition of biomedical service and repair, while simultaneously bolstering the growth of infusion pump sales within the oncology space and beyond.

First Biomedical’s results of operations are included in the Company’s consolidated statements of operations from the acquisition date.

Purchase Price Allocation

Pursuant to ASC 805, “Business Combinations,” the purchase price has been allocated to the assets acquired and liabilities assumed based upon their estimated fair values as of the acquisition date. The purchase price allocation was primarily based upon a valuation using income and cost approaches, and management’s estimates and assumptions. The excess of the purchase price over the net tangible and identifiable intangible assets was recorded as goodwill. For tax purposes, goodwill consists of both identifiable intangible assets (customer relationships and non-competition agreements from the table below) and unidentifiable intangible assets (goodwill from the table below). Goodwill is expected to be partially deductible for tax purposes. The purchase price allocation is based on a preliminary analysis and is subject to further adjustments. The allocation of the purchase price to the fair values of the assets acquired and liabilities assumed as of the transaction date is presented below (in thousands):

The stock purchase agreement provided for an adjustment to the purchase price based on final working capital as of the closing balance sheet, which was finalized during the year ended December 31, 2010 and resulted in an additional payment of $199 thousand, increasing the total purchase price.

Acquired property and equipment are being depreciated on a straight-line basis with estimated remaining lives ranging from 1 year to 14.5 years. Intangible assets are being amortized on a straight-line basis with estimated remaining lives ranging from 5 to 15 years reflecting the expected future value.

Seller Note

Pursuant to the terms of the Stock Purchase Agreement, as of the date of the acquisition the Company entered into a subordinated promissory note with the former majority shareholder of First Biomedical (the Seller) in the amount of $750 thousand. In accordance with the note, the Company will pay the Seller in equal installments over 24 months, which includes annual interest of 5%. As of March 31, 2011 the outstanding principal due on the note was $477 thousand.

Pro Forma Financial Information

The pro forma financial information in the table below summarizes the combined results of operations of the Company and First Biomedical as though the companies had been combined as of the beginning of the quarter ended March 31, 2010. The pro forma financial information is presented for informational purposes only and is not indicative of the results of operations that would have been achieved if the acquisition had taken place at the beginning of each period presented nor is it indicative of future results. We did not disclose the revenue and income of First Biomedical separately as it is not practical since the operations are already substantially integrated. The following pro forma financial information presented also includes the pro forma depreciation and amortization charges from acquired tangible and intangible assets, and related tax effects:

Table of Contents

Property and equipment consisted of the following as of March 31, 2011 and December 31, 2010 (amounts in thousands):

Included in pump equipment above is $5.2 million and $4.6 million, as of March 31, 2011 and December 31, 2010, respectively, worth of pumps obtained under various capital leases. Included in accumulated depreciation above is $818 thousand and $723 thousand, as of March 31, 2011 and December 31, 2010, respectively, associated with the same capital leases. Under the terms of all such capital leases, the Company does not presently hold title to these pumps, and will not obtain title until such time as the capital lease obligations are settled in full.

Depreciation expense for the three months ended March 31, 2011 and 2010 was $1.6 million and $1.1 million, respectively, which was recorded in cost of revenues and general and administrative expenses, for pump equipment and other fixed assets, respectively.

Goodwill

Goodwill arising from business combinations represents the excess of the purchase price over the estimated fair value of the net assets of the businesses acquired. The goodwill amount for the October 25, 2007 acquisition of InfuSystem is $56.6 million, and is based upon the final valuation analysis. The goodwill amount for the June 15, 2010 acquisition of First Biomedical is $7.5 million, and is based upon the final valuation analysis.

Impairment Testing

As of October 31, 2010, the Company performed its annual impairment test pursuant to ASC 350, “Intangibles — Goodwill and Other.” The fair value of the Company’s single reporting unit was estimated using a valuation model that combined an income and market approach, utilizing the discounted cash flow and guideline public company methods, respectively, which indicated that the fair value of its net assets exceeded the carrying value by less than 10%. Based on the results of the valuation, the Company determined there was no impairment of goodwill. No events have occurred subsequent to October 31, 2010 that indicates impairment may have occurred.

The Company has continued to monitor operational performance measures, general economic conditions and its market capitalization. A downward trend in one or more of these factors could cause the Company to reduce the estimated fair value of its reporting unit and recognize a corresponding impairment of goodwill in connection with a future goodwill impairment test.

The Company tests non-amortizable intangible assets (i.e., trade names) for impairment in accordance with ASC 350. The Company performed the annual impairment test at October 31, 2010, and determined there was no impairment. No events have occurred subsequent to October 31, 2010 that indicates impairment may have occurred. The intangible assets resulting from the October 25, 2007 acquisition of InfuSystem are based upon the final valuation analysis. The intangible assets resulting from the June 15, 2010 acquisition of First Biomedical are based upon the final valuation analysis.

Identifiable Intangible Assets

The carrying amount and accumulated amortization of intangible assets as of March 31, 2011 and December 31, 2010 were as follows (in thousands):

Amortization expense for intangible assets for the three months ended March 31, 2011 and 2010 was $645 thousand and $487 thousand, respectively, which was recorded in operating expenses. Expected annual amortization expense for intangible assets recorded as of March 31, 2011 is as follows (in thousands):

The Company has determined that the warrants discussed in Note 2, issued in connection with the IPO including the Overallotment Units, should be classified as liabilities in accordance with ASC 815. Therefore, the fair value of each instrument must be recorded as a liability on the Company’s balance sheet. Changes in the fair values of these instruments are reflected as adjustments to the amount of the recorded liabilities, and the corresponding gain or loss is recorded in the Company’s statement of operations within “Gain (loss) on derivatives”. At the date of the conversion of each warrant or portion thereof, or exercise of the warrants or portion thereof, as the case may be, the corresponding liability is reclassified as equity. As discussed in Note 10, the warrants expired in April 2011.

On February 16, 2010 the Company announced an Offer to Exchange common stock for outstanding warrants. At the time, the Company had 35,108,219 outstanding warrants. The exchange offer expired on March 17, 2010. Holders of the Company’s warrants had the option to exchange their warrants for either One (1) share of Common Stock for every thirty-five (35) Warrants tendered, or One (1) share of Common Stock for every twenty-five (25) Warrants tendered, provided the recipient agreed to be subject to a lock-up provision precluding transfer of the shares of Common Stock received for six months following the expiration of the Exchange Offer. The lock-up provision expired in September 2010. Based on the final count, 25,635,723 Warrants were properly tendered; 24,766,700 were tendered for shares of Common Stock subject to a lock-up, and 869,023 were tendered for unrestricted shares of Common Stock. Under the terms of the Exchange Offer, the Company issued an aggregate of 1,015,489 shares of Common Stock in exchange for the tendered Warrants. There are 8,329,638 publicly held warrants (issued in connection with the IPO) and 1,142,858 privately held warrants remaining after the exchange.

The fair value of the Company’s 8,329,638 warrants issued in connection with the IPO outstanding at March 31, 2011 and December 31, 2010 was liabilities of $83 thousand or $0.01 per warrant. These amounts are included in derivative liabilities within the Company’s balance sheet.

On July 20, 2010, the Company entered into a single interest rate swap with a July 30, 2010 effective date. The interest rate swap agreement, which expires in June 2014, had a notional value of $17.7 million on March 31, 2011, which represented approximately 65% of the outstanding underlying debt, and a fixed rate of 1.40%. The fair value of the interest rate swap outstanding at March 31, 2011 was a liability of $33 thousand. The Company has designated the swap as a cash flow hedge. In accordance with

On June 15, 2010, the Company entered into a credit facility with Bank of America, N.A. as Administrative Agent, and KeyBank National Association as Documentation Agent. The facility consists of a $30.0 million term loan and a $5.0 million revolving credit facility, both of which mature in June 2014. Interest on the term loan is payable at the Company’s choice of LIBOR plus 4.5%, or the Bank of America prime rate plus 3.5%. As of March 31, 2011, interest was payable at LIBOR plus 4.5%, which equaled approximately 4.76%.

Proceeds from the term loan were used to repay the outstanding balance of the Company’s debt held by Kimberly-Clark (I-Flow), as well as contribute to the acquisition consideration for First Biomedical.

In January 2011, the Company entered into the first amendment of the credit agreement, which defined the periods in which the fixed charge coverage ratio covenant should be calculated. In April 2011, the Company entered into the second amendment of the credit agreement, which modified the terms of capital expenditure limitation and capital lease indebtedness limitation covenants. In May 2011, the Company entered the third amendment of the credit agreement, which modified the definition of EBITDA.

As of March 31, 2011, the Company had a letter of credit in the amount of $81 thousand outstanding, leaving $4.9 million available on its revolving credit facility.

The term loan is collateralized by substantially all of the Company’s assets and requires the Company to comply with covenants, including but not limited to, financial covenants relating to satisfaction of a total leverage ratio, a fixed charge coverage ratio, and an annual limit on capital expenditures, including capital leases. In conjunction with the new credit facility, the Company incurred deferred debt issuance costs of $808 thousand. These costs are recognized in income using the effective interest method through the maturity date of June 15, 2014. Amortization of these costs for the three months ended March 31, 2011 was $62 thousand, which was recorded in interest expense.

In conjunction with the acquisition of First Biomedical, the Company entered into a subordinated promissory note with the former majority shareholder of First Biomedical (the Seller) in the amount of $750 thousand. In accordance with the note, the Company will pay the Seller in equal installments over 24 months, which includes annual interest of 5%. As of March 31, 2011 and December 31, 2010, the outstanding principal due on the note was $477 thousand and $569 thousand, respectively.

The Company sometimes enters into capital leases to finance the purchase of ambulatory infusion pumps. The pumps are capitalized into property and equipment at their fair market value, which equals the value of the future minimum lease payments, and are depreciated over the useful life of the pumps.

Maturities on the loan and capital leases are as follows (in thousands):

Provision for income taxes was a benefit of $146 thousand for the three months ended March 31, 2011, compared to an expense of $310 thousand for the three months ended March 31, 2010. In computing its income tax provision, the Company estimates its effective income tax rate for the full year and applies that rate to income earned through the reporting period.

The Company’s realization of its deferred tax assets is dependent upon many factors, including, but not limited to, the Company’s ability to generate sufficient taxable income. Certain deferred tax liabilities can also be considered as a source of future taxable income including those resulting from the acquisition. In prior years and through March 31, 2010, the Company had deferred tax assets to which a full valuation allowance was applied. Based upon the weight of available evidence, it was more likely than not that some portion or all of the deferred tax assets would not be realized. As a result of a review of the Company’s earnings history, existing deferred tax liabilities including those resulting from the First Biomedical acquisition, the Company removed the valuation allowance previously applied against the net deferred tax asset during the year ended December 31, 2010.

The Company recorded $190 thousand and $42 thousand in stock based compensation expense during the quarters ended March 31, 2011 and 2010, respectively, related to shares granted to the board of directors and officers.

As described in Note 3 to these consolidated financial statements, in accordance with the terms of the Stock Purchase Agreement with First Biomedical, the Company entered into a subordinated promissory note with the former majority shareholder of First Biomedical (the Seller) in the amount of $750 thousand. In accordance with the note, the Company will pay the Seller in equal installments over 24 months, which includes annual interest of 5%. As of March 31, 2011 the outstanding principal due on the note was $477 thousand. The Seller is a current employee of the Company, and is subject to an employment agreement. Also, the Seller owns Jan-Mar LLC and is the principal owner of the CW Investment Group LLC. In accordance with the Stock Purchase Agreement, the Company entered into operating lease agreements with Jan-Mar LLC and the CW Investment Group LLC, each of which owns one of the two office buildings utilized by First Biomedical in Olathe, Kansas. The terms of each lease is thirty six months, which commenced on July 1, 2010. Rent will be paid monthly in the amount of $5 thousand to Jan-Mar LLC and $3 thousand to the CW Investment Group LLC.

Certain of the Company’s directors committed to purchase up to $1.0 million of the Company’s warrants from the Company in a private placement at a price of $.70 per warrant subsequent to the filing of the preliminary proxy statement seeking stockholder approval of the acquisition of InfuSystem. Such officers and directors agreed not to sell or transfer the warrants until after the Company consummated a business combination. The warrants have an exercise price of $5.00 per share of common stock and became exercisable commencing on October 25, 2007, the acquisition date. All warrants expired on April 11, 2011. As of March 31, 2011, the Company has fully reserved the shares underlying the warrants as authorized but not issued. The warrants issued and sold in 2006 and 2007 were not registered under the Securities Act of 1933, as amended (the Securities Act). As a result, the warrants and the common stock issuable upon exercise of the warrants may could not be sold unless they have been registered pursuant to a registration statement filed under the Securities Act or pursuant to an available exemption from the registration requirements of the Securities Act as evidenced by an opinion of counsel reasonably satisfactory to the Company. As of March 31, 2011, there were 1,142,858 privately held warrants remaining after the exchange as discussed in Note 6 to these consolidated financial statements.

The Company is involved in legal proceedings arising out of the ordinary course and conduct of our business, the outcomes of which are not determinable at this time. We have insurance policies covering such potential losses where such coverage is cost effective. In the Company’s opinion, any liability that might be incurred by us upon the resolution of these claims and lawsuits will not, in the aggregate, have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows.

As of March 31, 2011, the Company had approximate minimum future operating lease commitments of (in thousands):

2007 Stock Incentive Plan

In 2007, the Company adopted the 2007 Stock Incentive Plan providing for the issuance of a maximum of 2,000,000 shares of common stock in connection with the grant of stock-based or stock-denominated awards. As of March 31, 2011, 77,000 common shares remained available for future grant under the 2007 Stock Incentive Plan.

Restricted Shares

Restricted shares entitle the holder to receive, upon meeting certain vesting criteria, a specified number of shares of the Company’s common stock. Stock-based compensation cost of restricted shares is measured by the market value of the Company’s common stock on the date of grant. Compensation cost associated with certain restricted share grants also takes into account market conditions in its measurement. The following table summarizes restricted share activity for the three months ended March 31, 2011:

As of March 31, 2011, there was $7.7 million of pre-tax total unrecognized compensation cost related to non-vested restricted shares, which will be adjusted for future forfeitures. The Company expects to recognize such cost over a period of approximately 14 years.

Stock-based compensation expense

Total stock-based compensation expense, which is included in selling, general and administrative expenses, was $248 thousand and $100 thousand for the three months ended March 31, 2011 and 2010.

The Company has defined contribution plans in which the Company contributes a certain percentage of employee contributions. Such Company matching contributions totaled $84 thousand and $15 thousand for the three months ended March 31, 2011 and 2010, respectively. The Company does not provide other post-retirement or post-employment benefits to its employees.

InfuSystem Holdings, Inc. Results of Operations for the three months ended March 31, 2011 compared to the three months ended March 31, 2010

Revenues

Our revenue for the quarter ended March 31, 2011 was $13.0 million, a 19% improvement compared to $10.9 million for the quarter ended March 31, 2010. The increase in revenues is primarily related to revenues generated by recently acquired First Biomedical as well as obtaining business at new customer facilities.

Gross Profit

Gross profit for the three months ended March 31, 2011 was $9.1 million, an increase of 11% compared to $8.1 million for the three months ended March 31, 2010. It represented 70% of revenues in the current year compared to 74% in the prior year. The decrease, as a percentage of revenues, is primarily related to a higher mix of pump sales, rentals and services as compared to third party billings, offset by a decrease in repair and maintenance costs which is a result of realized synergies related to the integration of First Biomedical operations.

Provision for Doubtful Accounts

Provision for doubtful accounts for the quarter ended March 31, 2011 was $1.2 million, compared to $1.4 million for the quarter ended March 31, 2010. The provision for doubtful accounts has decreased from 13% to 9% of revenues for the quarter ended March 31, 2011, compared to the quarter ended March 31, 2010. The decrease, as a percentage of revenue, is related to a decrease in direct patient billings, as well improved collectibility relating to sales, service and rental customers.

Amortization of Intangible Assets

Amortization of intangible assets for the quarter ended March 31, 2011 was $645 thousand, a 32% increase compared to $487 thousand for the quarter ended March 31, 2010. The increase is primarily related to additional intangible assets associated with the acquisition of First Biomedical, as well as amortization of new software.

Selling and Marketing Expenses

During the quarter ended March 31, 2011, our selling and marketing expenses were $2.4 million compared to $1.4 million for the quarter ended March 31, 2010. Selling and marketing expenses during these periods consisted of sales salaries, commissions and associated fringe benefit and payroll-related items, marketing, share-based compensation, travel and entertainment and other miscellaneous expenses. The increase in expenses is primarily related to expenses incurred by recently acquired First Biomedical as well as increased investments in the sales and marketing departments. As compared to the prior period, these expenses increased from 13% to 19% of revenues for the quarter ended March 31, 2011.

General and Administrative Expenses

During the quarter ended March 31, 2011, our general and administrative expenses were $4.5 million, compared to $3.3 million for the quarter ended March 31, 2010. The increase is primarily related to an increase in share-based compensation as well as expenses incurred at recently acquired First Biomedical. General and administrative expenses during these periods consisted primarily of administrative personnel salaries, fringe benefits and payroll-related items, professional fees, share-based compensation, insurance and other miscellaneous expenses. General and administrative expenses have increased from 30% to 35% of revenues for the quarter ended March 31, 2011, compared to the same period in the prior year. The increase, as a percentage of revenue, is primarily related to an increase in share-based compensation expense as well as a decrease in consignment revenue.

Other Income and Expenses

During the quarter ended March 31, 2011, there was no gain or loss recorded on derivatives as there was no change in the fair value of our warrants, compared to a loss of $389 thousand during the quarter ended March 31, 2010. Included in the losses for the previous quarter were unrealized losses from the change in the fair value of our warrants of $83 thousand and unrealized gains resulting from the change in the fair value of our single interest rate swap of $185 thousand. Also included in the loss for the quarter ended March 31, 2010, was a loss of $491 thousand recorded in connection with the warrant exchange. For more information, please refer to the discussion under “Summary of Significant Accounting Policies—Warrants and Derivative Financial Instruments” included in Note 2 and “Warrants and Derivative Financial Instruments” included in Note 6 to our Consolidated Financial Statements included in this Quarterly Report on Form 10-Q.

During the quarter ended March 31, 2011, we recorded interest expense of $541 thousand, compared to $805 thousand for the quarter ended March 31, 2010. These amounts consist primarily of interest paid on our term loans, cash payments associated with our terminated and new interest rate swaps, amortization of deferred debt issuance costs and interest expense on capital leases. The decrease is primarily related to a lower interest rate of the new term loan as well as a lower swap rate. These were offset by an increase in capital leases.

During the quarter ended March 31, 2011, we recorded income tax benefit of $146 thousand, compared to an expense of $310 thousand during the quarter ended March 31, 2010. The difference is primarily due to a decrease in pretax (loss) income (excluding loss on warrants) for the quarter ended March 31, 2011, compared to the quarter ended March 31, 2010.

Inflation

Management believes that there has been no material effect on our operations or financial condition as a result of inflation or changing prices of our infusion pumps during the period from December 31, 2010 through March 31, 2011.

Liquidity and Capital Resources

As of March 31, 2011, we had cash resources of $3.2 million compared to $5.0 million at December 31, 2010. The decrease in cash available to us was primarily due to capital expenditures and principal payments on our term loan and capital leases, partially offset by positive cash flow from operating activities.

Cash provided by operating activities for the three months ended March 31, 2011 was $2.1 million, compared to $1.5 million for the three months ended March 31, 2010. The increase is attributable to higher revenues and related gross profit as well as non-cash items such as depreciation, amortization of intangible assets and stock based compensation.

Cash used in investing activities for the three months ended March 31, 2011 was $2.4 million, compared to $537 thousand for the three months ended March 31, 2010. The increase is related to an increase in cash paid for capital acquisitions.

Cash used in financing activities for the three months ended March 31, 2011 was $1.5 million, compared to cash used in financing activities of $958 thousand for the three months ended March 31, 2010. The increase for the quarter ended March 31, 2011 is primarily due to an increase in principal payments on the term loan, treasury shares repurchased, and new capital leases entered into to finance the purchase of infusion pumps during the period between March 31, 2010 and March 31, 2011.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates, assumptions and judgments that affect the amounts reported in the financial statements, including the notes thereto. We consider critical accounting policies to be those that require more significant judgments and estimates in the preparation of our consolidated financial statements, including the following: revenue recognition, which includes contractual allowances; accounts receivable and allowance for doubtful accounts; warrants and derivative financial instruments; income taxes; and goodwill valuation. Management relies on historical experience and other assumptions believed to be reasonable in making its judgment and estimates. Actual results could differ materially from those estimates.

Management believes its application of accounting policies, and the estimates inherently required therein, are reasonable. These accounting policies and estimates are periodically reevaluated, and adjustments are made when facts and circumstances dictate a change.

Our accounting policies are more fully described under the heading “Summary of Significant Accounting Policies” in Note 2 to our Consolidated Financial Statements included in this Quarterly Report on Form 10-Q. We believe the following critical accounting estimates are the most significant to the presentation of our financial statements and require the most difficult, subjective and complex judgments:

Revenue Recognition

The majority of our revenue is rental revenue in the oncology market. Revenues are recognized predominantly under fee for service arrangements through equipment that we rent to patients. We recognize revenue only when all of the following criteria are met: 1) persuasive evidence of an arrangement exists; 2) services have been rendered; 3) the price to the customer is fixed or determinable; and 4) collectability is reasonably assured. Persuasive evidence of an arrangement is determined to exist, and collectability is reasonably assured, when 1) we receive a physician’s written order and assignment of benefits, signed by the physician and patient, respectively, and 2) we have verified actual pump usage and 3) we receive patient acknowledgement of assignment of benefits. We recognize rental revenue from electronic infusion pumps as earned, normally on a month-to-month basis.

21

Table of Contents

Pump rentals are billed at our established rates, which often differ from contractually allowable rates provided by third-party payors such as Medicare, Medicaid and commercial insurance carriers. All billings to third party payors are recorded net of provision for contractual adjustments to arrive at net revenues.

Due to the nature of the industry and the reimbursement environment in which we operate, certain estimates are required to record net revenues and accounts receivable at their net realizable values. Inherent in these estimates is the risk that they will have to be revised or updated as additional information becomes available. Specifically, the complexity of many third-party billing arrangements and the uncertainty of reimbursement amounts for certain services from certain payors may result in adjustments to amounts originally recorded. Due to continuing changes in the health care industry and third-party reimbursement, it is possible that management’s estimates could change in the near term, which could have an impact on our results of operations and cash flows.

Our largest payor is Medicare, which accounted for approximately 32% and 31% of our gross billings for the quarter ended March 31, 2011 and 2010, respectively. We have contracts with various individual Blue Cross/Blue Shield affiliates which in the aggregate accounted for approximately 21% and 23% of our gross billings for the quarter ended March 31, 2011 and 2010, respectively. No individual payor, other than Medicare and the Blue Cross/Blue Shield entities accounts for greater than 6% of our gross billings.

We recognize revenue for selling, renting and servicing new and pre-owned infusion pumps and other medical equipment to oncology practices as well as other alternate site settings including home care and home infusion providers, skilled nursing facilities, pain centers and others, when 1) persuasive evidence of an arrangement exists; 2) services have been rendered; 3) the price to the customer is fixed or determinable; and 4) collectability is reasonably assured. We perform an analysis to estimate sales returns and record an allowance. This estimate is based on historical sales returns.

Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable are reported at the estimated net realizable amounts from patients, third-party payors and other direct pay customers for goods provided and services rendered. We perform periodic analyses to assess the accounts receivable balances and record an allowance for doubtful accounts based on the estimated collectability of the accounts such that the recorded amounts reflect estimated net realizable value. Upon determination that an account is uncollectible, the account is written-off and charged to the allowance.

Accounts receivable are reduced by an allowance for amounts that could become uncollectible in the future. Our estimate for allowance for doubtful accounts is based upon management’s assessment of historical and expected net collections by payor. Due to continuing changes in the health care industry and third-party reimbursement it is possible that management’s estimates could change in the near term, which could have an impact on its financial position, results of operations, and cash flows.

Warrants and Derivative Financial Instruments

On April 18, 2006, we consummated our initial public offering (IPO) of 16,666,667 units. Each unit consists of one share of common stock and two redeemable common stock purchase warrants. Each warrant entitles the holder to purchase from us one share of our common stock at an exercise price of $5.00. On May 18, 2006, we sold an additional 208,584 units (the “Overallotment Units”) to FTN Midwest Securities Corp., the underwriter of our IPO (FTN Midwest), pursuant to a partial exercise by FTN Midwest of its overallotment option. The Warrant Agreement provides for us to register the shares underlying the warrants in the absence of our ability to deliver registered shares to the warrant holders upon warrant exercise.

ASC 815 requires freestanding derivative contracts that are settled in a company’s own stock, including common stock warrants, to be designated as equity instruments, assets or liabilities. Under the provisions of this standard, a contract designated as an asset or a liability must be carried at its fair value on a company’s balance sheet, with any changes in fair value recorded in the company’s results of operations. A contract designated as an equity instrument must be included within equity, and no fair value adjustments are required from period to period.

On February 16, 2010 we announced an Offer to Exchange common stock for outstanding warrants. At the time, we had 35,108,219 outstanding warrants. The exchange offer expired on March 17, 2010. Holders of our warrants had the option to exchange their warrants for either One (1) share of Common Stock for every thirty-five (35) Warrants tendered, or One (1) share of Common Stock for every twenty-five (25) Warrants tendered, provided the recipient agreed to be subject to a lock-up provision precluding transfer of the shares of Common Stock received for six months following the expiration of the Exchange Offer. The lock-up provision expired in September 2010. Based on the final count, 25,635,723 Warrants were properly tendered; 24,766,700 were tendered for shares of Common Stock subject to a lock-up, and 869,023 were tendered for unrestricted shares of Common Stock. Under the terms of the Exchange Offer, we issued an aggregate 1,015,489 shares of Common Stock in exchange for the tendered Warrants. After the exchange, there are 8,329,638 publicly held warrants and 1,142,858 privately held warrants outstanding.

22

Table of Contents

In accordance with ASC 815, the 8,329,638 remaining warrants issued in connection with the IPO and overallotment to purchase common stock must be settled in registered shares and are separately accounted for as liabilities as discussed in Note 6. The fair value of these warrants is shown on our balance sheet and the unrealized changes in the value of these warrants are shown in our statement of operations as “Gain (loss) on derivatives.” These warrants are freely traded on the “Over the Counter Bulletin Board.” Consequently, the fair value of these warrants is estimated as the market price of the warrant at each period end. To the extent the market price increases or decreases, our warrant liabilities will also increase or decrease with a corresponding impact on the Company’s results of operations within “Gain (loss) on derivatives”.

Sales of warrants that can be settled in unregistered shares of common stock, as discussed in Note 10, are treated as equity and included in additional paid in capital. The total warrants issued to date that can be settled in unregistered shares of common stock are 1,142,858 at an issue price of $.70 per warrant or a total issue price of $800 thousand.

ASC 815 requires that an entity recognize all derivatives as either assets or liabilities in the statement of financial position and measure those instruments at fair value.

The warrants expired on April 11, 2011.

Cash Flow Hedge

We are exposed to risks associated with future cash flows related to the variability of the interest rate on its term loan with Bank of America. In order to manage the exposure of these risks, we enter into interest rate swaps. On July 20, 2010, we entered into a single interest rate swap and designated the swap as a cash flow hedge. In accordance with ASC 815, the fair value of the swap is shown on our consolidated balance sheet within derivative liabilities, unrealized changes in the fair value are included in accumulated other comprehensive loss within the stockholders’ equity section on our consolidated balance sheet, and any realized changes would be included in our consolidated statement of operations within interest expense.

Income Taxes

We account for income taxes in accordance with ASC 740, “Income Taxes,” which requires that we recognize deferred tax liabilities and assets based on the differences between the financial statement carrying amounts and the tax basis of assets and liabilities, using enacted tax rates in effect in the years the differences are expected to reverse. Deferred income tax (expense) benefit results from the change in net deferred tax assets or deferred tax liabilities. A valuation allowance is recorded when, in the opinion of management, it is more likely than not that some or all of any deferred tax assets will not be realized. For more information, refer to the “Income Taxes” discussion included in Note 8.

Goodwill Valuation

Goodwill arising from business combinations represents the excess of the purchase price over the estimated fair value of the net assets of the businesses acquired.

In accordance with the provisions of ASC 350, “Intangibles – Goodwill and Other,” goodwill is tested annually for impairment or more frequently if circumstances indicate the possibility of impairment. Significant judgments required to estimate fair value include estimating future cash flows, and determining appropriate discount rates, growth rates and other assumptions. Changes in these estimates and assumptions could materially affect the determination of fair value which could trigger impairment. We performed the annual impairment test at October 31, 2010, and determined there was no impairment of goodwill. The fair value of our single reporting unit was estimated using a valuation model that combined an income and market approach, utilizing the discounted cash flow and guideline public company methods, respectively, which indicated that the fair value of its net assets exceeded the carrying value by less than 10%. No events have occurred subsequent to October 31, 2010 that indicates impairment may have occurred.

The relationship of our market capitalization to the carrying value of its net assets can impact estimates of these assumptions, and can therefore impact our judgment as to the fair value of its reporting unit when performing goodwill impairment tests. During 2010, our market capitalization remained fairly consistent with such experience in 2009. We evaluated the movement in our stock price along with its 2010 performance relative to expectations. In addition, we assessed several unique factors; a thinly traded, closely held, illiquid stock, an “overhang” created by having a significant amount of warrants outstanding (see Note 6), and a limited research or analyst coverage. The implied control premium was within the range of market control premiums paid in transactions of companies in the healthcare industry during the past three years. Based on this evaluation, we concluded that neither the market capitalization at October 31, 2010, nor the change vs. the prior year, were definitive indicators of impairment.

As our warrants expired in April 2011 and our common stock was listed on the NY AMEX in December 2010, the Company will monitor the impact of these factors as well as control premiums for healthcare transactions, operational performance measures, general economic conditions and its market capitalization. A downward trend in one or more of these factors could cause the Company to reduce the estimated fair value of its reporting unit and recognize a corresponding impairment of goodwill in connection with a future goodwill impairment test.

Table of Contents

At March 31, 2011, the principal plus accrued interest on our term loan with Bank of America was $27.2 million. The term loan bears interest at LIBOR plus 4.5% or the Bank of America prime rate plus 3.5%, at our option. The loan is a variable rate loan and therefore fair value approximates book value. See Note 7 to our Consolidated Financial Statements included in this Quarterly Report on Form 10-Q for further discussion of our term loan with Bank of America.

We are exposed to interest rate fluctuations on our underlying variable rate long-term debt. We utilize a single interest rate swap agreement to moderate approximately 65% of such exposure. We do not use derivative financial instruments for trading or other speculative purposes.

Based on the term loans and interest rate swaps outstanding, a decrease in LIBOR to zero (which is less than a 100 basis point decrease) would have increased our cash flow and pretax earnings by approximately $5 thousand for the quarter ended March 31, 2011. A 100 basis point increase in LIBOR would have decreased our cash flow and pretax earnings for the quarter ended March 31, 2011 by approximately $25 thousand.

We have classified certain warrants as derivative liabilities, which resulted in a liability of $83 thousand at March 31, 2011. We classified the warrants as derivative liabilities because there is a possibility that we may be required to settle the warrants in registered shares of common stock. We are required to compare the fair market value of these instruments from the date of the initial recording to their fair market value as of the end of each reporting period and to reflect the change in fair market value in our Consolidated Statements of Operations as a gain or loss for the applicable period. These warrants expired in April 2011.

Disclosure Controls and Procedures

We maintain disclosure controls and procedures, (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) that are designed to ensure that information required to be disclosed in our reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive Officer (principal executive officer) and Chief Financial Officer (principal accounting and financial officer), as appropriate, to allow timely decisions regarding required financial disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that a control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, with a company have been detected.

As of the end of the period covered by this Quarterly Report on Form 10-Q, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of March 31, 2011. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer each concluded that our disclosure controls and procedures are effective, at the reasonable assurance level, as of the end of the period covered by this Quarterly Report on Form 10-Q, as of March 31, 2011.

During the quarter ended March 31, 2011, we implemented a new general ledger and reporting system and were integrated into our financial reporting process. The implementation was not made in response to any deficiency in our internal controls. Implementation of this new system involved changes to our financial reporting procedures and controls. Our management believes that appropriate internal controls are in place with the new system. There were no other changes in our internal controls over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) that occurred during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

Change in Internal Control

Other than the changes described above, we have made no changes during three months ended March 31, 2011 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
