	1.                                      Basis of Presentation
	We have prepared the interim financial statements included in this Form 10-Q without an audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”).  We have condensed or omitted certain information and footnote disclosures, normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States, pursuant to such rules and regulations.  You should read these financial statements in conjunction with the financial statements and related notes thereto included in our 2012 Annual Report on Form 10-K.
	The financial statements presented herein as of September 30, 2013, and for the three months and nine months ended September 30, 2013 and 2012, reflect, in the opinion of management, all adjustments (which consist only of normal, recurring adjustments) necessary for a fair presentation of the financial position and the results of operations and cash flows for the periods presented. Management makes estimates and assumptions affecting the amounts of assets, liabilities, revenues and expenses we report, and our disclosure of contingent assets and liabilities at the date of the financial statements.  The results of the interim periods are not necessarily indicative of the results for the full year.  Accordingly, you should read these condensed financial statements in conjunction with the audited financial statements and the related notes thereto included in our 2012 Annual Report on Form 10-K.  Actual results could differ materially from these estimates and assumptions.
	Revenue Recognition for Milestone-based Arrangements
	In the current quarter we began recognizing revenue on certain new professional service contracts that include milestones using a proportional performance method of revenue recognition. Revenues from these fixed price professional service contracts are recognized as services are performed based on the achievement of specified milestones within the contracts and when the customer acknowledges that such criteria have been satisfied. We invoice our customer on these projects as agreed-upon project milestones are achieved and accepted by the customer. As of September 30, 2013 we recognized approximately $72,000 of services revenues under this method.
	Recently Issued Accounting Standards
	In July 2013, the FASB issued Accounting Standards Update No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU No. 2013-11”).  ASU No. 2013-11 provides guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. ASU No. 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of ASU No. 2013-11 will not have a significant impact on our consolidated financial statements.

	Common Stock Offering
	On August 8, 2013, we entered into an underwriting agreement relating to the public offering of 3,300,000 shares of our common stock at a price to the public of $11.00 per share, less underwriting discounts. In addition, we granted the underwriters a 30-day option to purchase up to an additional 495,000 shares at $11.00 per share to cover over-allotments, if any. On August 14, 2013, we completed the offering of 3,795,000 shares of common stock at a price to the public of $11.00 per share. The number of shares sold in the offering includes the underwriters’ full exercise of their over-allotment option. We received proceeds from the common stock sold by us, net of offering costs, of approximately $39.0 million.
	Restricted Stock:
	Total stock-based compensation expense related to restricted stock was $989,000 and $591,000 for the three months ended September 30, 2013 and 2012, respectively.  Total stock-based compensation expense related to restricted stock was $2.5 million and $1.6 million for the nine months ended September 30, 2013 and 2012, respectively.  Unrecognized stock-based compensation expense related to restricted stock was $5.8 million at September 30, 2013, which we will amortize ratably through May 2017.

	4.                                      Income Taxes
	We base the provision for income taxes upon estimated annual effective tax rates in the tax jurisdictions in which we operate.  For the three months ended September 30, 2013 and 2012, our effective tax rate was 28.9% and 41.2%, respectively.  For the nine months ended September 30, 2013 and 2012, our effective tax rate was 39.2% and 40.5%, respectively.  The lower tax rate for the three and nine months ended September 30, 2013 as compared to the same periods in 2012 resulted primarily from the impact of federal graduated tax rates on our estimated annual taxable income. Additionally, we recognized benefits from discrete item adjustments of approximately $101,000 and $5,000 during the three months ended September 30, 2013 and 2012, respectively. These adjustments decreased our effective tax rate to 28.9% and 41.2% for the three months ended September 30, 2013 and 2012, respectively. We recognized benefits from discrete item adjustments of approximately $101,000 and $32,000 during the nine months ended September 30, 2013 and 2012, respectively. These adjustments decreased our effective tax rate to 39.2% and 40.5% for the nine months ended September 30, 2013 and 2012, respectively. We expect our annual effective tax rate for 2013 to be 39.8%.
	As part of the process of preparing financial statements, we estimate federal and state income taxes. Management estimates the actual current tax exposure together with assessing temporary differences resulting from different treatment for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which we include within our balance sheet. Management must then assess the likelihood that we will utilize deferred tax assets to offset future taxable income during the periods in which we may deduct these temporary differences.  For the three and nine months ended September 30, 2013, we recorded income tax expense of $335,000 and $3.1 million, respectively, with effective tax rates of 28.9% and 39.2%.
	We assess our uncertain tax positions for tax years that are still open for examination.  As of September 30, 2013 and 2012, we had no unrecognized tax benefits which would affect our effective tax rate if recognized.
	We classify interest and penalties arising from the underpayment of income taxes in the statement of operations under general and administrative expenses. As of September 30, 2013 and 2012, we had no accrued interest or penalties related to uncertain tax positions. The tax years 2009-2012 remain open to examination by both the Federal government and by other major income taxing jurisdictions to which we are subject.
	Our ability to utilize a portion of our net operating loss carryforwards to offset future taxable income is subject to certain limitations under Section 382 of the Internal Revenue Code due to changes in our equity ownership. We do not believe that an ownership change under Section 382 has occurred, and therefore, no such limitations exist.

	5.                                      Acquisitions
	On October 4, 2012, we purchased substantially all of the assets and liabilities of Strategic Technologies, Inc. (“StraTech”) from StraTech and Midas Medici Group Holdings, Inc. (“Midas,” parent company of StraTech and, together with StraTech, the “Sellers”). StraTech is an IT services and solutions firm that shares our focus on optimizing enterprise data centers and IT infrastructure through a common product and services portfolio designed to help customers increase business agility. We purchased StraTech for a purchase price of approximately $11.0 million, comprised of a cash payment of approximately $13.2 million, which is offset by a receivable due from the Sellers of approximately $4.2 million resulting from the preliminary estimated working capital adjustment. In addition, we issued 269,783 shares of our common stock with a value of approximately $2.0 million. Those shares have been deposited in an escrow account as security for certain indemnification obligations of the Sellers. Pursuant to the asset purchase agreement, Sellers are obligated to pay us an amount equal to the difference between the actual tangible net assets on the closing date and the Sellers’ good faith estimated net tangible assets as set forth in the asset purchase agreement.  We recorded the receivable due from Sellers of approximately $4.2 million related to this payment at the acquisition date.  Sellers have provided us with a “Notice of Disagreement,” which states that they are disputing the amount owed to us in connection with this reconciliation payment.  The asset purchase agreement contains an arbitration provision for disputes over the value of tangible net assets.  The amount of the receivable we recorded may be impacted by the resolution of the arbitration proceeding.  As of the filing of this Form 10-Q, no resolution has been reached, and the parties are reviewing the working capital calculations and determining the timing for arbitration.
	We estimated the fair value of the assets acquired and liabilities assumed of StraTech primarily using a discounted cash flow approach with respect to identified intangible assets and goodwill.  We based this approach upon our estimates of future cash flows from the acquired assets and liabilities and utilized a discount rate consistent with the inherent risk associated with the acquired assets and liabilities assumed.  As of December 31, 2012, the fair value of the acquired assets was provisional as we had not yet finalized net working capital adjustments that are included within the “Notice of Disagreement” discussed above.  The total purchase price has been allocated to StraTech’s net tangible and identifiable intangible assets based on their estimated fair values as of October 4, 2012, and has been adjusted through September 30, 2013. Adjustments to provisional amounts during the measurement period that were the result of information that existed as of the acquisitions date require the revision of comparative prior period financial information when reissued in subsequent financial statements. Accordingly, our 2012 balance sheet has been retroactively adjusted to account for those changes. The changes resulted in a $313,000 reduction in goodwill and did not impact our income statement.
	The following table summarizes the final allocation of the purchase price including measurement period adjustments:
		(in thousands)
	Assets acquired at their fair value:
	Accounts receivable, net	$	9,712
	Deferred revenue costs	8,521
	Equipment	432
	Finite-lived intangibles	15,920
	Goodwill	5,021
	Other assets	628
	Total assets acquired	40,234
	Liabilities assumed at their fair value:
	Accounts payable	17,645
	Customer deposits	751
	Deferred revenue	10,289
	Accrued expenses	566
	Other liabilities	29
	Total liabilities assumed	29,280
	Net purchase price	$	10,954
	The fair value of the acquired assets included a finite-lived intangible asset consisting of customer relationships that have an estimated life of five years and an indefinite-lived asset consisting of goodwill of approximately $5.0 million which will be deductible for tax purposes over a 15 year period.  We are amortizing the finite-lived intangible asset we acquired in the StraTech acquisition over its useful life using an accelerated amortization method, to match the pattern in which the economic benefits of that asset are expected to be consumed. We paid a premium over the fair value of the net tangible and identified intangible assets acquired (i.e., goodwill) because this acquisition expanded our market share and physical presence across the Eastern seaboard of the United States and allows us to diversify our product offerings from certain manufacturers and expand our high-margin professional and managed services business lines. We expect to experience operational synergies and efficiencies through combined general and administrative corporate functions.
	The following table provides a reconciliation of the net purchase price for StraTech as compared to the cash payment for purchase:
		(in thousands)
	Net purchase price	$	13,172
	Less receivable due from seller	(4,243		)
	Less value of shares issued	2,025
	Payment in cash for purchase	$	10,954
	Integration costs for 2013 and 2012 include salaries, benefits and retention bonuses of exiting employees, some of whom assisted with the initial integration of StraTech.  In addition, transaction costs for 2012 include legal, audit and other outside service fees necessary to complete our acquisition of StraTech, which were expensed.  Total integration and transaction costs were $7,000 and $103,000 for the three months ended September 30, 2013 and 2012, respectively. Total integration and transaction costs were $80,000 and $123,000 for the nine months ended September 30, 2013 and 2012, respectively.

	6.                                      Goodwill and Finite Life Intangible Assets
	We assess the carrying amount of our goodwill for potential impairment annually or more frequently if events or a change in circumstances indicate that impairment may have occurred.  We perform an impairment test for finite-lived assets, such as intangible assets, and other long-lived assets, such as fixed assets, whenever events or changes in circumstances indicate that the carrying value of such assets may not be recoverable.  Circumstances that could represent triggering events and therefore require an interim impairment test of goodwill or evaluation of our finite-life intangible assets or other long-lived assets include the following:  loss of key personnel, unanticipated competition, higher or earlier than expected customer attrition, deterioration of operating performance, significant adverse industry, economic or regulatory changes or a significant decline in market capitalization.
	We have only one operating and reporting unit that earns revenues, incurs expenses and makes available discrete financial information for review by our chief operations decision maker.  Accordingly, we complete our goodwill impairment testing on this single reporting unit.
	In conducting the annual impairment test of our goodwill, qualitative factors are first examined to determine whether the existence of events, or circumstances, indicate that it is more likely than not that the fair value of a reporting unit is less than its carrying amount.  If it is determined that it is more likely than not that the fair value of the reporting unit is less than its carrying amount, a two-step impairment test is applied.  The first step of the goodwill impairment test, used to identify potential impairment, compares the fair value of our market capitalization with the carrying value of our net assets. If our total market capitalization is at or below the carrying value of our net assets, we perform the second step of the goodwill impairment test to measure the amount of impairment loss we record, if any.  We consider goodwill impairment test estimates critical due to the amount of goodwill recorded on our balance sheet and the judgment required in determining fair value amounts.
	Goodwill was $37.5 million as of September 30, 2013 and December 31, 2012 and includes the measurement period adjustments discussed in Note 5 above. We conducted our annual goodwill impairment test as of December 31, 2012, our last measurement date.  Based on this analysis, we determined that there was no impairment to goodwill.  We will continue to monitor conditions and changes that could indicate impairment of our recorded goodwill.
	At each of September 30, 2013 and December 31, 2012, we determined that no triggering events had occurred during the quarter and our finite-lived assets and long-lived assets were not impaired.
	Identified intangible assets are summarized as follows:

	Our short term investments consist principally of commercial paper and corporate bonds. We categorize these investments as trading securities and record them at fair value. We classify investments with maturities of 90 days or less from the date of purchase as cash equivalents; investments with maturities of greater than 90 days from the date or purchase but less than one year generally as short term investments; and investments with maturities of greater than one year from the date of purchase generally as long term investments.

	8.                                      Fair Value Measurements
	Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.  In determining fair value for assets and liabilities required or permitted to be recorded at fair value, we consider the principal or most advantageous market in which it would transact and the assumptions that market participants would use when pricing the asset or liability.  We apply fair value measurements for both financial and nonfinancial assets and liabilities.  We have no nonfinancial assets or liabilities that require measurement at fair value on a recurring basis as of September 30, 2013.
	The fair value of our financial instruments, including cash and cash equivalents, short-term investments, accounts receivable, accounts payable, line of credit and accrued liabilities, approximate cost because of their short maturities.
	We use the three-level fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair values.  The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).  The three levels of the fair value hierarchy are described below:
	·                  Level 1 — Unadjusted quoted prices available in active markets for the identical assets or liabilities at the measurement date.
	·                  Level 2 — Significant other observable inputs available at the measurement date, other than quoted prices included in Level 1, either directly or indirectly.
	·                  Level 3 — Significant unobservable inputs that we cannot corroborate by observable market data and thus reflect the use of significant management judgment.  We generally determine these values using pricing models based on assumptions our management believes other market participants would make.
	The fair value hierarchy requires the use of observable market data when available.  In instances in which the inputs used to measure fair value fall into different levels of the fair value hierarchy, we determine the fair value measurement based on the lowest level input that is significant to the fair value measurement in its entirety.  Our assessment of the significance of a particular item to the fair value measurement in its entirety requires judgment, including the consideration of inputs specific to the asset or liability.  The following table sets forth, by level within the fair value hierarchy, the accounting of our financial assets and/or liabilities at fair value on a recurring basis as of September 30, 2013 and December 31, 2012 according to the valuation techniques we used to determine their fair value(s).

	We occasionally enter into sales-type lease agreements with our customers resulting from the sale of certain products. Our lease receivables are recorded at cost within the accounts receivable and long-term lease receivables balances on our balance sheet and are due in installments over the lives of the leases. Cash received and applied against the receivable balance is recorded within changes in operating assets and liabilities in the net cash provided by operating activities section of the statement of cash flows.  Finance income is derived over the term of the sales-type lease arrangement as the unearned income on financed sales-type leases is earned. Unearned income is amortized over the life of the lease using the interest method.  The present value of net investment in sales-type lease receivables of $1.6 million and $1.0 million at September 30, 2013 and December 31, 2012, respectively, is reflected net of unearned income of $46,000 and $60,000 at September 30, 2013 and December 31, 2012, respectively. As of September 30, 2013, scheduled maturities of minimum lease payments receivable were as follows for the fiscal years ended December 31:

	10.                               Line of Credit
	On July 17, 2013, we entered into a credit agreement with Castle Pines Capital LLC (“CPC”), an affiliate of Wells Fargo Bank, National Association.  The credit agreement provides for a floor plan line of credit and a revolving facility in a maximum combined aggregate amount of $40 million.  Borrowing under the revolving facility cannot exceed the lesser of (i) $40 million minus the amount outstanding under the floor plan line of credit or (ii) a borrowing base consisting of 85% of certain eligible accounts and 100% of channel financed inventory, subject to CPC’s ability to impose reserves in the future.  The floor plan line of credit finances certain purchases of inventory by us from vendors approved by CPC and the revolving facility is used for working capital purposes and permitted acquisitions.
	The amounts outstanding under the revolving facility will bear interest at a per annum rate of 2.0% above Wells Fargo’s one-month LIBOR rate (approximately 0.18% at September 30, 2013).  Advances under the floor plan line of credit will not bear interest so long as they are paid by the applicable payment due date and advances that remain outstanding after the applicable payment due date will bear interest at a per annum rate of LIBOR plus 4%.  We are obligated to pay quarterly to CPC an unused commitment fee equal to 0.50% per annum on the average daily unused amount of the combined facility, with usage including the sum of any advances under either the floor plan line of credit or the revolving facility.  The combined facility and certain bank product obligations owed to Wells Fargo or its affiliates are secured by substantially all of our personal property. The credit agreement terminates on July 17, 2016 and we will be obligated to pay certain prepayment fees if the credit agreement is terminated prior to that date.
	The credit agreement contains customary representations, warranties, covenants and events of default, including but not limited to, covenants restricting our ability to (i) grant liens on our assets, (ii) make certain fundamental changes, including merging or consolidating with another entity or making any material change in the nature of our business, (iii) make certain dividends or distributions, (iv) make certain loans or investments, (v) guarantee or become liable in any way on certain liabilities or obligations of any other person or entity, or (vi) incur certain indebtedness. Our prior credit agreement (as discussed below) included similar restrictions.
	The credit agreement contains certain covenants regarding our financial performance, including (i) a minimum tangible net worth of at least $20 million, (ii) a maximum funded debt to EBITDA of no more than 3.00 to 1.00, and (iii) a minimum quarterly net income of at least $250,000.
	The credit agreement replaced the credit facility we had in place with Wells Fargo, which was terminated upon the effectiveness of the credit agreement.  We did not incur any early termination fees or penalties in connection with the termination of the prior credit agreement.  Wells Fargo serves and may continue to serve as our transfer agent and has performed and may continue to perform commercial banking and financial services for us for which they have received and may continue to receive customary fees.  The prior credit agreement provided for a revolving line of credit for a total maximum borrowing amount of $20.0 million.
	We had outstanding advances of $6.0 million on the prior credit agreement at December 31, 2012. At September 30, 2013, we had no outstanding advances on the prior credit agreement or the revolving facility, but had outstanding advances of $12.3 million on the floor plan line of credit related to the purchase of inventory from a vendor.

	In the current quarter we began recognizing revenue on certain new professional service contracts that include milestones using a proportional performance method of revenue recognition. Revenues from these fixed price professional service contracts are recognized as services are performed based on the achievement of specified milestones within the contracts and when the customer acknowledges that such criteria have been satisfied. We invoice our customer on these projects as agreed-upon project milestones are achieved and accepted by the customer. As of September 30, 2013 we recognized approximately $72,000 of services revenues under this method.
