1. Business and Basis of Presentation

PositiveID Corporation, formerly known as VeriChip Corporation (the “Company,” “us,” “we,” or “our”), is a Delaware corporation formed in November 2001. The Company commenced operations in January 2002. On February 14, 2007, the Company completed an initial public offering of its common stock, selling 3,100,000 shares of its common stock at a price of $6.50 per share.

On July 18, 2008, the Company completed the sale of all of the outstanding capital stock of Xmark Corporation, its wholly-owned Canadian subsidiary (“Xmark”), to Stanley Canada Corporation (“Stanley”) for $47.9 million in cash, which consisted of the $45 million purchase price plus a balance sheet adjustment of $2.9 million. Under the terms of the stock purchase agreement, $4.5 million of the proceeds were held in escrow for a period of 12 months to provide for indemnification obligations under the stock purchase agreement, if any. As a result, the Company recorded a gain on the sale of Xmark of $10.7 million, with $4.5 million of that gain deferred until the escrow was settled. The Xmark business included all of the operations of our previously reported healthcare security and industrial segments. The financial position, results of operations and cash flows of Xmark for 2008 have been reclassified as a discontinued operation.

Following the completion of the sale of Xmark to Stanley, the Company retired all of its outstanding debt for a combined payment of $13.5 million and settled all contractual payments to officers and management of the Company and Xmark for $9.1 million. In addition, the Company issued a special dividend of $15.8 million on August 28, 2008.

On November 12, 2008, the Company entered into an Asset Purchase Agreement (“APA”) with Digital Angel and Destron Fearing Corporation, a wholly-owned subsidiary of Digital Angel, which collectively are referred to as, “Digital Angel.” The terms of the APA included the purchase by the Company of patents related to an embedded bio-sensor system for use in humans, and the assignment of any rights of Digital Angel under a development agreement associated with the development of an implantable glucose sensing microchip. The Company also received covenants from Digital Angel and Destron Fearing that will permit the use of intellectual property of Digital Angel related to the Company’s VeriMed business without payment of ongoing royalties, as well as inventory and a limited period of technology support by Digital Angel. The Company paid Digital Angel $500,000 at the closing of the APA, which was recorded in the financials as research and development expense.

During the quarter ended June 30, 2009, the Company finalized the process related to the indemnification obligations supported by the $4.5 million escrow. On July 20, 2009, the Company received $4.4 million of the previously escrowed funds, which was net of a $115 thousand settlement to Stanley as the final balance sheet adjustment. As a result, the Company recognized a $4.4 million previously deferred gain in its statement of operations during the nine months ended September 30, 2009.

On September 4, 2009, the Company, VeriChip Acquisition Corp., a Delaware corporation and wholly-owned subsidiary of the Company (the “Acquisition Subsidiary”), and Steel Vault Corporation, a Delaware corporation (“Steel Vault”) signed an Agreement and Plan of Reorganization (the “Merger Agreement”), dated September 4, 2009, as amended, pursuant to which the Acquisition Subsidiary was merged with and into Steel Vault on November 10, 2009, with Steel Vault surviving and becoming a wholly-owned subsidiary of the Company (the “Merger”). Upon the consummation of the Merger, each outstanding share of Steel Vault’s common stock was converted into 0.5 shares of common stock of the Company. At the closing of the Merger, the Company changed its name to PositiveID Corporation, changed its stock ticker symbol with Nasdaq to “PSID” effective November 11, 2009, and continues to be listed on the Nasdaq Capital Market.

On September 29, 2009, the Company entered into a financing commitment of up to $10,000,000 with Optimus Technology Capital Partners, LLC (“Optimus”) under which Optimus is potentially committed to purchase up to $10 million of the Company’s convertible Series A Preferred Stock in one or more tranches. The Company plans to use the funds to develop a virus triage detection system for the H1N1 virus, to develop anin vivoglucose-sensing RFID microchip (discussed below) and to support its working capital requirements and general corporate purposes. See Note 5 — Financing Agreements, for more information.

During the three months ended September 30, 2009, through a development program with Receptors LLC (“Receptors”), the companies launched Phase I of the development of a triage detection system for the H1N1 virus was launched. On October 6, 2009, in a separate development program, the Company launched the Phase II development of itsin vivoglucose-sensing RFID microchip with Receptors. In conjunction with this development program, the Company received an exclusive license to two of Receptors platform patents for use with these two applications. Phase I of the H1N1 triage detection system and Phase II of the glucose-sensing microchip development programs are expected to be completed during the first half of 2010. In conjunction with these two projects, the Company paid Receptors $200,000 and 350,000 shares of restricted common stock.

POSITIVEID CORPORATION
Notes to Unaudited Condensed Consolidated Financial Statements

The Company has historically developed, marketed, and sold radio frequency identification (frequently referred to as RFID) systems used for the identification and protection of people in the healthcare market. The Company’s VeriMed system uses the human-implantable passive RFID microchip that is used in patient identification applications, securely linking a patient to their personal health record as maintained in the Company’s proprietary database. Each implantable VeriChip microchip contains a unique verification number that is read when it is scanned by the Company’s scanner. In October 2004, the U.S. Food and Drug Administration, or FDA, cleared the Company’s VeriMed system for use in medical applications in the United States.

On March 5, 2009, the Company established a new division to evaluate clean and alternative energy companies for potential strategic transactions or investment and as a result established a new subsidiary, VeriGreen Energy Corporation. The Company incurred costs of $0.3 million, primarily consisting of transaction costs related to the evaluation of several strategic opportunities and organization costs.

Beginning in the fourth quarter of 2009, with the acquisition of Steel Vault, the Company intends to pursue its strategy to offer identification tools and technologies for consumers and businesses, including healthcare identification products, initially focused on the Health Link personal health record and the identification security products currently offered by NationalCreditReport.com.

The Company also intends to continue the development of the H1N1 triage detection system, the glucose sensing RFID microchip and other health related products, built on the Company’s core intellectual property.

The accompanying unaudited condensed consolidated financial statements of the Company and its subsidiaries as of September 30, 2009 and December 31, 2008 (the December 31, 2008, financial information included in this report has been extracted from the Company’s audited financial statements included in its Annual Report on Form 10-K, as amended, for the year ended December 31, 2008), and for the three and nine months ended September 30, 2009 and 2008 have been prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X under the Securities Exchange Act of 1934. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of the Company’s management, all adjustments (including normal recurring adjustments) considered necessary to present fairly the unaudited condensed consolidated financial statements have been made.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of sales and expenses during the reporting period. Actual results could differ from those estimates. Included in these estimates are assumptions about allowances for excess inventory, bad debt reserves, lives of long lived assets, lives of intangible assets, assumptions used in Black-Scholes valuation models, estimates of the fair value of acquired assets and assumed liabilities, the determination of whether any impairment is to be recognized on goodwill or intangibles, among others.

The unaudited condensed consolidated statements of operations for the three and nine months ended September 30, 2009 and 2008 are not necessarily indicative of the results that may be expected for the entire year. These statements should be read in conjunction with the consolidated financial statements and related notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2008.

Fair Value of Financial Instruments

The carrying values of financial instruments including cash and accounts payable approximate fair value due to the relatively short term nature of these instruments.

The Company adopted the provisions of Financial Accounting Standards Board (“FASB”) ASC 820-10, “Fair Value Measurements and Disclosures” (“ASC 820-10”) for financial assets and liabilities effective January 1, 2008, and adopted ASC 820-10 for non-financial assets and non-financial liabilities effective January 1, 2009. ASC 820-10 clarifies the principle that fair value should be based on the assumptions market participants would use when pricing an asset or liability and establishes a fair value hierarchy that prioritizes the information used to develop those assumptions. The statement utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. A brief description of those three levels is as follows:

The three levels of the fair value hierarchy under ASC 820-10 are described below:

• Level 1—Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

• Level 2—Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates); and inputs that are derived principally from or corroborated by observable market data by correlation or other means.

• Level 3—Inputs that are both significant to the fair value measurement and unobservable.

The Company’s investment in the common stock purchase warrant to purchase 333 thousand common shares of Steel Vault, as further discussed in Note 4 — Note Receivable, are classified as Level 2 under ASC 820-10 hierarchy. The warrant investment in the Company is valued monthly using a Black-Scholes model with observable market inputs.

Investments are classified within Level 3 of the fair value hierarchy because they trade infrequently (or not at all) and therefore have little or no readily available pricing. Unobservable inputs are used to measure fair value to the extent that observable inputs are not available. The note receivable is classified within Level 3 of the fair value hierarchy.

Valuations for Level 3 investments are adjusted when changes to inputs and assumptions are corroborated by evidence such as transactions in similar instruments, convertible offerings in the equity or debt, and changes in financial ratios or cash flows of the borrower and the guarantor’s financial ability to repay the obligation in the event of a default. The note receivable is guaranteed by the Company’s president and chief financial officer who is the chief executive officer of Steel Vault, the borrower.

For positions that are not traded in active markets or are subject to transfer restrictions, valuations are adjusted to reflect illiquidity and/or non-transferability and such adjustments are generally based on available market information. In the absence of such evidence, management’s best estimate is used.

The values assigned to investments and any unrealized gains or losses reported are based on available information and do not necessarily represent amounts that might be realized if a ready market existed and such difference could be material. Furthermore the ultimate realization of such amounts depends on future events and circumstances and therefore valuation estimates may differ from the value realized upon disposition of individual positions.

The following table sets forth information about the level within the fair value hierarchy at which the Company’s investments are measured at September 30, 2009 (expressed in thousands):

			Fair Value
	Fair Value		Hierarchy
Assets
Warrant	$	273		2
Note receivable (includes $19 interest receivable)	$	495		3
Total	$	768

Notes to Unaudited Condensed Consolidated Financial Statements

The following summarizes changes in fair value of the Company’s Level 3 assets for the nine months ended September 30, 2009. The information reflects gains and losses for the period for assets categorized as Level 3 as of September 30, 2009 (expressed in thousands):

	Level 3

Balance — December 31, 2008	$	—
Unrealized gains — (representing accretion of debt discount)		10
Purchases		466
Balance — September 30, 2009	$	476

The Company adopted the provisions of FASB ASC 825-10, “Financial Instruments” (“ASC 825-10”) on January 1, 2008. ASC 825-10 permits entities to choose to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. ASC 825-10 also establishes presentation and disclosure requirements designed to facilitate comparisons between entities that chose different measurement attributes for similar assets and liabilities. The Company has elected not to measure any eligible items at fair value.

Recent Accounting Pronouncements

Effective July 1, 2009, the Company adopted the FASB Accounting Standards Codification (“ASC”) 105-10, “Generally Accepted Accounting Principles” (“ASC 105-10”). ASC 105-10 establishes the FASB Accounting Standards Codification as the source of authoritative accounting principles recognized by the FASB to be applied by non-governmental entities in the preparation of financial statements in conformity with GAAP. Rules and interpretive releases of the SEC under authority of federal securities laws are also sources of authoritative U.S. GAAP for SEC registrants. The codification did not change GAAP but reorganizes the literature. References for FASB guidance throughout this document have been updated for the codification.

Effective January 1, 2009, the Company adopted ASC 805-10, “Business Combinations” (“ASC 805-10”). Under ACS 805-10, an acquiring entity is required to recognize all the assets acquired and liabilities assumed in a transaction at the acquisition-date fair value with limited exceptions. ACS 805-10 establishes principles and requirements for how an acquirer recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, any non-controlling interest in the acquiree and the goodwill acquired. This statement also establishes disclosure requirements which will enable users to evaluate the nature and financial effects of the business combination. The Company expensed $0.2 million of due diligence costs relating to a potential acquisition target during the period ended September 30, 2009.

The Company adopted the provisions of ASC 855-10, “Subsequent Events” (“ASC 855-10”) in the second quarter of 2009. ASC 855-10 establishes (1) the period after the balance sheet date during which management of a reporting entity should evaluate events or transactions that may occur for potential recognition or disclosure in the financial statements, (2) the circumstances under which an entity should recognize events or transactions occurring after the balance sheet date in its financial statements, and (3) the disclosures that an entity should make about events or transactions that occurred after the balance sheet date. The Company has evaluated any subsequent events through November 10, 2009.

The Company adopted ASC 810-10-65-1, “Noncontrolling Interests in Consolidated Financial Statements—an amendment of ARB No. 51” on January 1, 2009. This establishes accounting and reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. It clarifies that a noncontrolling interest in a subsidiary is an ownership interest in the consolidated entity that should be reported as equity in the consolidated financial statements. In addition, it changes the way the consolidated income statement is presented by requiring consolidated net income to be reported at amounts that include the amounts attributable to both the parent and the noncontrolling interest. ASC 810-10-65-1 also establishes a single method of accounting for changes in a parent’s ownership interest in a subsidiary that do not result in deconsolidation and requires that a parent recognize a gain or loss in net income when a subsidiary is deconsolidated. ASC 810-10-65-1 is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2008 and earlier adoption is prohibited. ASC 810-10-65-1 shall be applied prospectively as of the beginning of the fiscal year in which this statement is initially applied, except for the presentation and disclosure requirement which shall be applied retrospectively for all periods presented. The adoption of ASC 810-10-65-1 had no impact on the Company’s condensed financial position, results of operations, cash flows or financial statement disclosures.

In June 2009, the FASB finalized SFAS No. 167,Amending FASB interpretation No. 46(R), which was later superseded by the FASB Codification and included in ASC topic 810. The provisions of ASC 810 provide guidance in determining whether an enterprise has a controlling financial interest in a variable interest entity. This determination identifies the primary beneficiary of a variable interest entity as the enterprise that has both the power to direct the activities of a variable interest entity that most significantly impacts the entity’s economic performance, and the obligation to absorb losses or the right to receive benefits of the entity that could potentially be significant to the variable interest entity. This pronouncement also requires ongoing reassessments of whether an enterprise is the primary beneficiary and eliminates the quantitative approach previously required for determining the primary beneficiary. New provisions of this pronouncement are effective January 1, 2010. The Company is currently evaluating the impact of adopting this pronouncement.

In August of 2009, the FASB issued ASC Update 2009-5, an update to ASC 820, “Fair Value Measurements and Disclosures”. This update provides amendments to reduce potential ambiguity in financial reporting when measuring the fair value of liabilities. Among other provisions, this update provides clarification in circumstances in which a quoted price in an active market for the identical liability is not available, a reporting entity is required to measure fair value using one or more of the valuation techniques described in ACS Update 2009-5. The adoption of this update in the third quarter of 2009 did not have a material affect on Company’s condensed consolidated financial statements.

Accounting Standard Update No. 2009-15, Accounting for Own-Share Lending Arrangements in Contemplation of Convertible Debt Issuance or Other Financing.In October 2009, the Financial Accounting Standards Board (“FASB”) issued Update No. 2009-15 as an amendment to the subtopic 470-20,Debt with Conversion and Other Options,to address the accounting for own-share lending arrangements entered in contemplation of a convertible debt issuance or other financing. ASC 470-20-25-20A establishes that at the date of issuance, a share-lending arrangement entered into on an entity’s own shares in contemplation of a convertible debt offering or other financing shall be measured at fair value (in accordance with Topic 820) and recognized as an issuance cost, with an offset to additional paid-in capital in the financial statements of the entity. ASC 470-20-35-11A establishes that if it becomes probable that the counterparty to a share-lending arrangement will default, the issuer of the share-lending arrangement shall recognize an expense equal to the then fair value of the unreturned shares, net of the fair value of probable recoveries. The issuer of the share-lending arrangement shall remeasure the fair value of the unreturned shares each reporting period through earnings until the arrangement consideration payable by the counterparty becomes fixed. Subsequent changes in the amount of the probable recoveries should also be recognized in earnings. ASC 470-20-45-2A establishes that loaned shares are excluded from basic and diluted earnings per share unless default of the share-lending arrangement occurs. ASC 470-20-50-2A adds new disclosures that must be made in any period in which a share-lending arrangement is outstanding as follows: (a) description of any outstanding share-lending arrangements, (b) number of shares, term, circumstances under which cash settlement would be required, (c) any requirements for the counterparty to provide collateral, (d) entity’s reason for entering into the share-lending arrangement, (e) fair value of the issuance cost associated with the arrangement, (f) treatment for the purpose of calculating earnings per share, (g) unamortized amount of the issuance cost associated with the arrangement, (h) classification of the issuance cost associated with the arrangement, (i) amount of interest cost recognized relating to the amortization and (j) any amounts of dividends paid related to the loaned shares that will not be reimbursed. This Accounting Standard Update shall be effective for fiscal years beginning on or after December 15, 2009 and interim periods within those fiscal years for arrangements outstanding entered into on or after the beginning of the first reporting period that begins on or after June 15, 2009. Early adoption is not permitted. The Company is evaluating the impact on financial statements regarding this update.

Research and development expense of approximately $10 thousand was recorded in the three and nine months ended September 30, 2009 for these shares.

Stock-based compensation expense is reflected in the condensed consolidated statement of operations in selling, general and administrative expense.

The Company’s computation of expected life was determined based on the simplified method. The interest rate was based on the U.S. Treasury Yield curve in effect at the time of grant. The Company’s computation of expected volatility is based on the historical volatility of the Company’s comparable companies’ average historical volatility.

2. Principles of Consolidation

The financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant inter-company transactions and balances had been eliminated in consolidation.

4. Note Receivable

On June 4, 2009, the Company invested $500 thousand in Steel Vault pursuant to a secured convertible promissory note (the “Note”). The two year Note was collectible on demand on or after June 4, 2010, accrued interest at a rate of twelve percent and was secured by substantially all of Steel Vault’s assets, including the assets of National Credit Report.com, LLC, a wholly-owned subsidiary of Steel Vault. The security interest held by the Company on the assets was senior to any other security interest on the assets pursuant to a Subordination and Intercreditor Agreement between the Company and Blue Moon Energy Partners LLC, a Florida limited liability company (“Blue Moon”). The Note could be prepaid at any time without penalty and matured on June 4, 2011. The unpaid principal and accrued and unpaid interest under the Note could be converted at any time into common stock of Steel Vault at a price of $0.30 per share.

The investment included a common stock purchase warrant given to the Company to purchase 333 thousand common shares of Steel Vault at a price of $0.30 per share. The fair market value at issuance and September 30, 2009, was $34 thousand and $273 thousand, respectively. Interest receivable as of September 30, 2009 was $10 thousand.

The Company valued each component of the investment as of the investment period and allocated the $500 thousand investment proportionately to the Note and common stock purchase warrant based on their respective fair values on June 4, 2009.

The financing transaction also included a guaranty of collection given by Mr. Caragol, the Company’s president and chief financial officer and the chief executive officer of Steel Vault for the benefit of the Company. See Note 10 — Related Party Transactions, for more information.

5. Financing Agreements

On September 29, 2009, the Company entered into a Convertible Preferred Stock Purchase Agreement (the “Purchase Agreement”) with Optimus Capital Partners, LLC doing business as Optimus Technology Capital Partners, LLC (“Optimus”) under which Optimus is committed to purchase up to $10 million shares of convertible Series A Preferred Stock of the Company (the “Preferred Stock”) in one or more tranches. Under the terms of the Purchase Agreement, from time to time and at the Company’s sole discretion, the Company may present Optimus with a notice to purchase such Preferred Stock (the “Notice”).

To facilitate the transactions contemplated by the Purchase Agreement, R & R Consulting Partners, LLC, a company controlled by Scott R. Silverman, the Company’s chairman and chief executive officer, will loan shares of common stock to Optimus equal to 135% of the aggregate purchase price for each tranche pursuant to Stock Loan Agreements between R & R Consulting Partners, LLC and Optimus. R & R Consulting Partners, LLC was paid $100 thousand fee in October 2009 plus will be paid 2% interest for the fair value of the loaned shares for entering into the stock loan arrangement. The aggregate amount of shares loaned under any and all Stock Loan Agreements, together with all other shares sold by or on behalf of the Company pursuant to General Instruction I.B.6. to Form S-3, can not exceed one-third of the aggregate market value of the voting and non-voting common equity held by non-affiliates of the Company in any 12 month period. R & R Consulting Partners, LLC may demand return of some or all of the borrowed shares (or an equal number of freely tradable shares of common stock) at any time on or after the six-month anniversary date such borrowed shares were loaned to Optimus, but no such demand may be made if there are any shares of Preferred Stock then outstanding. If a permitted return demand is made, Optimus will return the borrowed shares within three trading days after such demand (or an equal number of freely tradable shares of common stock). Optimus may return the borrowed shares in whole or in part, at any time or from time to time, without penalty or premium. On September 29, 2009, October 8, 2009, and October 21, 2009, R & R Consulting Partners, LLC loaned Optimus 1.3 million, 800,000 and 600,000 shares, respectively, of Company common stock.

POSITIVEID CORPORATION
Notes to Unaudited Condensed Consolidated Financial Statements

Optimus is obligated to purchase such Preferred Stock on the tenth trading day after any Notice date, subject to satisfaction of certain closing conditions, including (i) that the Company is listed for and trading on a trading market, (ii) the representations and warranties of the Company set forth in the Purchase Agreement are true and correct as if made on each tranche date, (iii) Optimus shall have received a commitment fee of $800 thousand payable only on the first tranche closing date in the event the gross proceeds from the first tranche closing exceed $800 thousand; and (iv) that no such purchase would result in Optimus and its affiliates beneficially owning more than 9.99% of the Company’s common stock. In the event the closing bid price of the Company’s common stock during any one or more of the nine trading days following the delivery of a Notice falls below 75% of the closing bid price on the trading day prior to the Notice date and Optimus determines not to complete the tranche closing, then the Company may, at its option, proceed to issue some or all of the applicable shares, provided that the conversion price for the Preferred Stock that is issued shall reset at the lowest closing bid price for such nine trading day period.

In addition, redemption of the Preferred Stock by the Company, to the extent such Preferred Stock shall not have been converted into shares of Common Stock, shall be mandatory in the event that the Company does not receive stockholder approval for the transactions described in the Purchase Agreement on or before March 31, 2010.

On September 29, 2009 the Company exercised the first tranche of this financing, to issue 296 shares of Preferred Stock, for a tranche amount of approximately $3.0 million. In support of this tranche, R & R Consulting Partners, LLC loaned Optimus 1.3 million shares of common stock. This tranche closed on October 13, 2009, and the Company received proceeds of approximately $3.0 million, less the fees due on the entire financing commitment of $800 thousand. On November 5, 2009, the Company closed the second tranche of this financing, issuing 166 shares of Preferred Stock, for a tranche amount of approximately $1.7 million. In support of this tranche, R & R Consulting Partners, LLC loaned Optimus approximately 1.4 million shares of common stock.

The Black-Scholes model, which the Company used to determine compensation expense, required the Company to make several key judgments including:

• the value of the Company’s common stock;

• the expected life of issued stock options;

• the expected volatility of the Company’s stock price;

• the expected dividend yield to be realized over the life of the stock option; and

• the risk-free interest rate over the expected life of the stock options.

The Company prepared these estimates based upon its historical experience, the stock price volatility of comparable publicly-traded companies and its best estimation of future conditions.

The fair values of the options granted were estimated on the grant date using the Black-Scholes valuation model based on the following weighted-average assumptions:

	2009		2008
Expected dividend yield		N/A		—
Expected stock price volatility		N/A		50	%
Risk-free interest rate		N/A		4.51	%
Expected term (in years)		N/A		6.0

The following stock options and restricted stock outstanding as of September 30, 2009 and 2008 were not included in the computation of dilutive income (loss) per share because the net effect would have been anti-dilutive:

	For the Three Months Ended				For the Nine Months Ended

Securities excluded from the diluted earnings (loss) per share calculation because the exercise prices were greater than the average market price
Stock Options (1)		—		—		809		—

(1) These stock options represent the number of stock options outstanding at the end of the respective period. At the point that the exercise price is less than the average market price, these options have the potential to be dilutive and application of the treasury method would reduce this amount.

8. Income Taxes

The Company had an effective tax rate of nil for the three and nine months ended September 30, 2009 and 2008. However, it has not recorded a tax benefit for the resulting U.S. net operating loss carryforwards, as the Company has determined that a valuation allowance against its net U.S. deferred tax assets was appropriate based primarily on its historical operating results.

During the three and nine months ended September 30, 2009, the Company recognized a gain of $4.4 million from the sale of Xmark in 2008. This gain resulted in taxable income in 2008, which resulted in the Company utilizing a portion of its net operating loss carryforward through the release of the valuation allowance against those tax attributes.

The Company adopted the provisions of ASC 740-10, “Income Taxes” relating to uncertainty in income taxes effective January 1, 2008. The Company used a two-step approach to recognizing and measuring tax benefits when the benefits’ realization is uncertain. The first step is to determine whether the benefit is to be recognized, and the second step is to determine the amount to be recognized:

• income tax benefits should be recognized when, based on the technical merits of a tax position, the entity believes that if a dispute arose with the taxing authority and were taken to a court of last resort, it is more likely than not (i.e., a probability of greater than 50 percent) that the tax position would be sustained as filed; and

• if a position is determined to be more likely than not of being sustained, the reporting enterprise should recognize the largest amount of tax benefit that is greater than 50 percent likely of being realized upon ultimate settlement with the taxing authority.

The implementation of ASC 740-10 did not result in any adjustment to the Company’s beginning tax positions. The Company continues to fully recognize its tax benefits, which are offset by a valuation allowance to the extent that it is more likely than not that the deferred tax assets will not be realized.

The Company recognizes any interest accrued related to unrecognized tax benefits or exposures in interest expense and penalties in operating expenses. During the three and nine months ended September 30, 2009 and 2008, there was no such interest or penalty.

On October 8, 2008, Steel Vault entered into a sublease with Digital Angel for its corporate headquarters located in Delray Beach, Florida, consisting of approximately 7,911 feet of office space, which space the Company shares with Steel Vault. The rent for the entire twenty-one-month term of the sublease is $158,000, which Steel Vault paid in one lump sum upon execution of the sublease. The Company reimbursed Steel Vault for one-half of the sublease payment, representing the Company’s share of the total cost of the sublease. In addition, in order to account for certain shared services and resources, the Company and Steel Vault operate under a shared services agreement, in connection with which Steel Vault currently pays the Company $6,500 a month. During the three and nine months ended September 30, 2009, the Company recorded $21,500 and $66,500, respectively, for shared services fees from Steel Vault. The Company did not record any payments for shared services fees from Steel Vault for the three and nine months ended September 30, 2008.

On June 4, 2009, the Company closed a debt financing transaction with Steel Vault for $500 thousand pursuant to Note. The financing transaction included a common stock purchase warrant sold to the Company to purchase 333 thousand common shares of Steel Vault. The financing transaction also included a guaranty of collection given by Mr. Caragol for the benefit of the Company, for which Mr. Caragol received a common stock purchase warrant from Steel Vault. See Note 4 — Note Receivable, for more information.

Financing Transaction

To facilitate the transactions contemplated by the Purchase Agreement, R & R Consulting Partners, LLC, a company controlled by Mr. Silverman, will loan shares of common stock to Optimus equal to 135% of the aggregate purchase price for each tranche pursuant to Stock Loan Agreements between R & R Consulting Partners, LLC and Optimus. On September 29, 2009, October 8, 2009, and October 21, 2009, R & R Consulting Partners, LLC loaned Optimus 1.3 million, 800,000 and 600,000 shares, respectively, of Company common stock.

12. Subsequent Events

On September 29, 2009, the Company exercised the first tranche of the financing with Optimus pursuant to the Purchase Agreement, pursuant to which it sold 296 shares of Preferred Stock, for a tranche amount of approximately$3.0 million. This tranche closed on October 12, 2009, and the Company received proceeds of approximately $3.0 million, less the fees due on the entire financing commitment of $800 thousand. On November 5, 2009, the Company closed the second tranche of this financing, issuing 166 shares of Preferred Stock, for a tranche amount of approximately $1.7 million. In support of this tranche, R & R Consulting Partners, LLC loaned Optimus 1.4 million shares of common stock. See Note 5 — Financing Agreements, for more information.

On October 6, 2009, the Company entered into a License Agreement with Receptors to obtain an exclusive license to use certain intellectual property of Receptors for internal research, internal development and quality control purposes and to make, sell, offer to sell, import and export tangible products covered by patents and patent applications (the “Licensed Products”) owned by Receptors, in their application to the development of an implantable glucose sensing device for use in the human body and applications in related fields. In connection with the License Agreement, the Company and Receptors entered into a Development/Master Agreement pursuant to which the Company will engage the services of Receptors to develop a glucose sensing device for use in the human body. Under the Development/Master Agreement, Receptors will provide glucose sensing system optimization and demonstrate a fluorescence system bench scale prototype by March 31, 2010. As consideration, the Company made a cash payment of $100,000 to Receptors and issued 150,000 restricted shares of Company common stock as payment under the Development/Master Agreement. The Company must pay Receptors royalties of forty-five percent (45%) of the net sales of the Licensed Products relating to implantable glucose sensing device for use in the human body markets and applicational areas in related fields worldwide. The Company must also pay Receptors forty-five percent (45%) of any revenue received from the sale of the Licensed Products, other than for sales described in the immediately preceding sentence.

On November 10, 2009 the Company completed the acquisition of Steel Vault pursuant to the Merger Agreement. See Note 1 — Business and Basis of Presentation for further details.

The Company will issue approximately 5,067,290 shares of its common stock in connection with the Merger, and has reserved an additional 3,802,409 shares of its common stock for issuance in connection with the Company’s assumption of Steel Vault’s outstanding options and warrants. No fractional shares of the Company’s common stock will be issued in connection with the Merger. Instead, the Company will make a cash payment to each Steel Vault stockholder who would otherwise receive a fractional share. The Company will account for the merger using the acquisition method of accounting for business combinations, with the Company being considered the acquiror of Steel Vault, in conformity with GAAP. This means that the Company will allocate the purchase price to the fair value of assets, including identifiable intangible assets acquired and liabilities assumed from the current minority owners of Steel Vault at the effective time of the Merger, with the excess purchase price, if any, being recorded as goodwill. Under the acquisition method of accounting, goodwill is not amortized but is tested for impairment at the time of the acquisition and at least annually thereafter.
