SPIRE CORPORATION AND SUBSIDIARIES

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

June 30, 2014 and 2013

1. Description of the Business

Spire Corporation ("Spire" or the "Company") and its subsidiaries along with its variable interest entity develop, manufacture and market highly-engineered products and services in two principal business areas: (i) capital equipment for the photovoltaic solar industry and (ii) biomedical, through its variable interest entity, N2 Biomedical LLC ("N2 Bio"), generally bringing to bear expertise in materials technologies, surface science and thin films across both business areas, discussed below.

In the photovoltaic solar area, the Company develops, manufactures and markets specialized equipment for the production of terrestrial photovoltaic modules from solar cells.  The Company's equipment has been installed in approximately 200 factories in 50 countries.  The equipment market is very competitive with major competitors located in the U.S., Japan and Europe.  The Company's flagship product is its Spi-Sun simulator which tests module performance.  The Company's other product offerings include turn-key module lines and to a lesser extent other individual equipment.  To compete the Company offers other services such as training and assistance with module certification.  The Company also provides turn-key services to its customers to backward integrate to solar cell manufacturing.

In the biomedical area, through its variable interest entity, N2 Bio, the Company provides value-added surface treatments to manufacturers of orthopedic and other medical devices that enhance the durability, antimicrobial characteristics or other material characteristics of their products; and performs sponsored research programs into practical applications of advanced biomedical technologies.

Liquidity

Operating results will depend upon revenue growth or decline and product mix, as well as the timing of shipments of higher priced products from the Company's solar equipment line.  Export sales, which amounted to 46% and 41% of net sales and revenues for the three and six months ended June 30, 2014, respectively, and 37% and 34% of net sales and revenues for the three and six months ended June 30, 2013, respectively, continue to constitute a significant portion of the Company's net sales and revenues.

The Company has incurred losses from operations.  Losses from operations were $1.0 million and $3.6 million for the three and six months ended June 30, 2014, respectively. Losses from operations were $1.8 million and $4.4 million for the three and six months ended June 30, 2013, respectively. Net cash used in operating activities was $1.9 million for the six months ended June 30, 2014. Net cash used in operating activities was $1.9 million for the six months ended June 30, 2013, which includes $150 thousand of cash used in operating activities of discontinued operations. As of June 30, 2014, the Company had unrestricted cash and cash equivalents of $1.0 million compared to $4.0 million as of December 31, 2013.  The Company's credit facilities with Silicon Valley Bank expired on April 30, 2014 and will not be renewed, and the Company has repaid the outstanding amounts. These factors raise substantial doubt about the Company's ability to continue as a going concern. The Company currently believes that its existing cash resources at June 30, 2014, will be sufficient to fund its operations into the second half of 2014; however, the Company cannot provide any assurances of its continued operations and liquidity.

The Company has various options on how to fund future operational losses and working capital needs, including but not limited to sales of equity, bank debt, private lenders, the sale or license of assets and technology, or joint ventures involving cash infusions, as it has done in the past; however, there are no assurances that the Company will be able to sell equity, obtain or access bank debt or alternative financing, sell or license assets or technology or enter into such joint ventures on a timely basis and at appropriate values or on acceptable terms, if at all.  The Company has developed several plans including potential strategic alternatives, cost reduction efforts and expanding revenue in other markets to offset a decline in business due to global economic conditions.  The Company's inability to successfully implement its cost reduction strategies, expand revenue in other markets or to replace its expired credit facilities, could adversely impact the Company's ability to continue as a going concern.

The financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern.

2. Interim Financial Statements

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission ("SEC") regarding interim financial reporting.  Certain information

- 5-

and footnote disclosures normally included in consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted in accordance with such rules and regulations. These unaudited condensed consolidated financial statements should be read in conjunction with the annual audited consolidated financial statements and notes thereto for the year ended December 31, 2013, included in the Company’s Annual Report on Form 10-K filed with the SEC.

In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to fairly present the Company’s financial position as of June 30, 2014 and December 31, 2013 and the results of operations for the three and six months ended June 30, 2014 and 2013. The results of operations for the three and six months ended June 30, 2014 are not necessarily indicative of the results to be expected for the fiscal year ending December 31, 2014.  The unaudited condensed consolidated balance sheet as of December 31, 2013 has been derived from audited financial statements as of that date.  

Summary of Significant Accounting Policies

With the exception of the Company's revenue recognition policy which has been updated below, the significant accounting policies followed by the Company are set forth in Note 2 to the Company’s consolidated financial statements in its Annual Report on Form 10-K for the year ended December 31, 2013, filed with the SEC on March 31, 2014.

Revenue Recognition

The Company derives its revenues from continuing operations from three primary sources: (1) sales of commercial products including, but not limited to, solar energy manufacturing equipment; (2) biomedical and coating technology services; and (3) United States government funded research and development contracts.

The Company generally recognizes product revenue upon shipment of products provided there are no uncertainties regarding customer acceptance, persuasive evidence of an arrangement exists, the sales price is fixed or determinable, and collectability is reasonably assured. These criteria are generally met at the time of shipment when the risk of loss and title passes to the customer.

The Company's OEM (original equipment manufacturer) capital equipment solar energy business builds complex customized machines to order for specific customers.  Most orders are sold on a FOB Bedford, Massachusetts (or EX-Works Factory) basis and other orders are sold on a Carriage and Insurance Paid (or CIP), or on rare situations, a Delivery Duty Unpaid (or DDU) basis. It is the Company's policy to recognize revenues for this equipment when title of the product has passed to the customer, provided that customer acceptance is obtained prior to shipment and the equipment is expected to operate the same in the customer's environment as it does in the Company's environment.  When an arrangement with the customer includes future obligations or customer acceptance, revenue is recognized when those obligations are met or customer acceptance has been achieved.  Typically, the Company is able to separate arrangements with multiple elements into more than one unit of accounting as it relates to the passage of title to goods, training and installation services when no right of return exists. The Company allocates total fees under contract to each element using the relative selling price method and revenue is recognized upon delivery of each element. The Company's management performs extensive analysis to determine the relative selling price of each unit of accounting. The Company allocates revenue in arrangements using its best estimate of selling price if neither vendor-specific objective evidence ("VSOE") nor third-party evidence (“TPE”) of selling price exists.  The Company determines estimated selling price ("ESP") of each deliverable based on a number of factors, including internal costs, gross margin targetsandhistorical sales of similar units, as well as external factors such as market and competitive conditions.

The Company's biomedical services provides advanced medical device surface treatment processes for performance improvement of orthopedic devices. The Company's coating technology services are provided to both industrial and consumer electronic applications. It is the Company's policy to recognize revenues from these services when services are provided to the customer.

The Company recognizes revenues and estimated profits on long-term government contracts on a percent complete basis where the circumstances are such that total profit can be estimated with reasonable accuracy and ultimate realization is reasonably assured. The Company records revenue and profit utilizing the percentage of completion method using a cost-to-cost methodology. A percentage of the contract revenues and estimated profits is determined utilizing the ratio of costs incurred to date to total estimated cost to complete on a contract by contract basis. Profit estimates are revised periodically based upon changes in facts, and any losses on contracts are recognized immediately. Some of the contracts include provisions to withhold a portion of the contract value as retainage until such time as the United States government performs an audit of the cost incurred under the contract.  The Company's policy is to take into revenue the full value of the contract, including any retainage, as it performs against

- 6-

the contract since the Company has not experienced any substantial losses as a result of audits performed by the United States government.

New Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606). The guidance in this ASU affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards. The guidance in this ASU supersedes the revenue recognition requirements in Accounting Standards Codification ("ASC") No. 605, Revenue Recognition, and most industry-specific guidance throughout the Industry Topics of the Codification. Additionally, this ASU supersedes some cost guidance included in ASC No. 605-35, Revenue Recognition-Construction-Type and Production-Type Contracts. In addition, the existing requirements for the recognition of a gain or loss on the transfer of nonfinancial assets that are not in a contract with a customer are amended to be consistent with the guidance on recognition and measurement in this ASU. For a public entity, the amendments in this ASU are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Retrospective application of the amendments in this ASU are required. The new guidance must be adopted using either a full retrospective approach for all periods presented in the period of adoption (with some limited relief provided) or a modified retrospective approach. Early application is not permitted under GAAP. The Company is currently assessing the impact of this ASU on its unaudited condensed consolidated financial statements.

In July 2013, the FASB issued ASU No. 2013-11 ("ASU 2013-11"), Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. The update requires, unless certain conditions exists, an unrecognized tax benefit, or a portion of an unrecognized tax benefit, to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, similar tax loss, or a tax credit carryforward. ASU 2013-11 is effective prospectively for reporting periods beginning after December 15, 2013, with early adoption permitted. Retrospective application is permitted. The application of this ASU did not have an impact on the Company's unaudited condensed consolidated financial statements.

3. Accounts Receivable/Advances on Contracts in Progress

Net accounts receivable, trade and advances on contracts in progress consists of the following:

(in thousands)	June 30, 2014			December 31, 2013
Amounts billed	$	1,383		$	1,396
Accrued revenue	18			18
Gross accounts receivable - trade	1,401			1,414
Less:  Allowance for doubtful accounts	(32		)	—
Net accounts receivable - trade	$	1,369		$	1,414
Advances on contracts in progress	$	1,851		$	1,433

Accrued revenue represents revenues recognized on contracts for which billings have not been presented to customers as of the balance sheet date.

The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to pay amounts due. The Company actively pursues collection of past due receivables as the circumstances warrant. Customers are contacted to determine the status of payment and senior accounting and operations management are included in these efforts as is deemed necessary. A specific reserve will be established for past due accounts when it is probable that a loss has been incurred and the Company can reasonably estimate the amount of the loss. The Company does not record an allowance for government receivables and invoices backed by letters of credit as collection is reasonably assured. Bad debts are written off against the allowance when identified. There is no dollar threshold for account balance write-offs. While rare, a write-off is only recorded when all efforts to collect the receivable have been exhausted.

Advances on contracts in progress represent billings that have been presented to the customer, as either deposits or progress payments against future shipments, but revenue has not been recognized.

4. Inventories and Deferred Costs of Goods Sold

- 7-

Inventories, net of $1.1 million and $1.0 million of reserves at June 30, 2014 and December 31, 2013, respectively, and deferred cost of goods sold consist of the following at: 

(in thousands)	June 30, 2014		December 31, 2013
Raw materials	$	1,047	$	1,310
Work in process	2,721		2,004
Finished goods	401		502
Net inventory	$	4,169	$	3,816
Deferred cost of goods sold	$	27	$	849

Deferred cost of goods sold represents costs of equipment that has shipped to the customer and title has passed but not all revenue recognition criteria have yet been met.  The Company defers these costs until the related revenue is recognized.

5. Loss Per Share

The following table provides a reconciliation of the denominators of the Company’s reported basic and diluted loss per share computations for the periods ended:

	Three Months Ended June 30,		Six Months Ended June 30,
	2014	2013	2014	2013
Weighted average number of common and common equivalent shares outstanding – basic and diluted	9,207,874	9,207,874	9,207,874	9,144,482

For the three and six months ended June 30, 2014, 21,751 and 21,289 shares of common stock, respectively, and for the three and six months ended June 30, 2013, 3,554 and 4,375 shares of common stock, respectively, issuable relative to stock options were excluded from the calculation of diluted shares because their inclusion would have been anti-dilutive, due to the Company’s net loss position.

In addition, for the three and six months ended June 30, 2014, 543,122 and 543,122 shares of common stock, respectively, and for the three and six months ended June 30, 2013, 660,446 and 660,446 shares of common stock, respectively, issuable relative to stock options were excluded from the calculation of diluted shares because their inclusion would have been anti-dilutive, due to the Company's net loss position and their exercise prices exceeding the average market price of the stock for the period.

6. Operating Segments and Related Information

The Company's operations are focused on two primary business areas:  Spire Solar (comprised of solar equipment and solar research) and Spire Biomedical (comprised of biomedical surface treatments and biophotonics research).  Spire Solar and Spire Biomedical operate out of the Company's facility in Bedford, Massachusetts. Each business area is independently managed and has separate financial results that are reviewed by the Board of Directors and Chief Executive Officer and the chief executive officers of each operating division.

On September 18, 2013, the Company completed the sale of the Bio Business Unit to N2 Bio, whereas the Company has a controlling financial interest in N2 Bio and is less than wholly-owned by the Company. N2 Bio qualifies as a variable interest entity and the Company is determined to be the primary beneficiary; therefore assets, liabilities and results of operations of N2 Bio are consolidated into the Company's financial statements. The Bio Business Unit is being reported in our biomedical segment. See Note 13 to the unaudited condensed consolidated financial statements.

In calculating income (loss) from operations for individual business units, substantial administrative expenses incurred at the operating level that are common to more than one segment are allocated on a net sales basis. Certain corporate expenses of an operational nature are also allocated to the divisions based on factors including occupancy, employment, and purchasing volume. All intercompany transactions have been eliminated.

The following table shows net sales and revenues by geographic area (based on customer location):

Revenues from the delivery of biomedical services to two customers accounted for 21% and 13% of total net sales and revenues for the six months ended June 30, 2013.

Three customers represented approximately 27%, 20% and 18% , respectively, of net accounts receivable, trade at June 30, 2014 and two customers represented approximately 36% and 17% of net accounts receivable, trade at December 31, 2013.

7. Intangible and Other Assets

Patents amounted to $70 thousand and $62 thousand, net of accumulated amortization of $895 thousand and $871 thousand, at June 30, 2014 and December 31, 2013, respectively. Licenses amounted to $71 thousand and $110 thousand, net of accumulated amortization of $77 thousand and $38 thousand, at June 30, 2014 and December 31, 2013, respectively. Patent cost is primarily composed of costs associated with securing and registering patents that the Company has been awarded or that have been submitted to the U.S. Patent and Trademark Office, and the Company believes will be approved. License cost is composed of the cost to acquire rights to the underlying technology or know-how. These costs are capitalized and amortized over their useful lives or terms, using the straight-line method. There are no expected residual values related to these patents.

Amortization expense, relating to patents and licenses, was approximately $31 thousand and $14 thousand for the three months ended June 30, 2014 and 2013, respectively. Amortization expense, relating to patents and licenses, was approximately $63 thousand and $27 thousand for the six months ended June 30, 2014 and 2013, respectively.

For disclosure purposes, the table below includes future amortization expense for patents and licenses owned by the Company as well as estimated amortization expense related to patents that remain pending at June 30, 2014 of $109 thousand. This estimated expense for patents pending assumes that the patents are issued immediately, and therefore are being amortized over five years on a straight-line basis. Estimated amortization expense for the periods ending December 31, is as follows: 

(in thousands)	Amortization Expense
2014 remaining 6 months	$	53
2015	51
2016	38
2017	33
2018	33
2019	19
2020 and future	23
	$	250

Also included in other assets are refundable deposits made by the Company of approximately $150 thousand and $150 thousand at June 30, 2014 and December 31, 2013, respectively.

8. Available-for-Sale Investments

Available-for-sale investments consist of assets held as part of the Spire Corporation Non-Qualified Deferred Compensation Plan. These investments have been classified as available-for-sale investments and are reported at fair value, with unrealized gains and losses included in accumulated other comprehensive income. The unrealized gain on these marketable securities was zero and $393 thousand as of June 30, 2014 and December 31, 2013, respectively. During the six months ended June 30, 2014, the Company recorded a realized gain on the sale of available-for-sale investments of $541 thousand. The participant of the deferred compensation plan retired as Chief Executive Officer and President of the Company on December 31, 2013. The participant received deferred compensation payments of approximately $1.2 million in January 2014 and $2.8 million in May 2014, which was funded by the sale of these securities.

9. Fair Value Measurements

The hierarchy established under ASC 820-10, Fair Value Measures and Disclosures ("ASC 820-10") gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). As required by ASC 820-10, the Company's available-for-sale investments are classified within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The three levels of the fair value hierarchy under ASC 820-10, and its applicability to the Company's available-for-sale investments, are described below:

- 10-

Level 1 - Pricing inputs are quoted prices available in active markets for identical investments as of the reporting date. As required by ASC 820-10, the Company does not adjust the quoted price for these investments, even in situations where the Company holds a large position and a sale could reasonably impact the quoted price.

Level 2 - Pricing inputs are quoted prices for similar investments, or inputs that are observable, either directly or indirectly, for substantially the full term through corroboration with observable market data. Level 2 includes investments valued at quoted prices adjusted for legal or contractual restrictions specific to these investments.

Level 3 - Pricing inputs are unobservable for the investment, that is, inputs that reflect the reporting entity's own assumptions about the assumptions market participants would use in pricing the asset or liability. Level 3 includes investments that are supported by little or no market activity.    

Valuation Techniques

Fair value is a market-based measure considered from the perspective of a market participant who would buy the asset or assume the liability rather than the Company's own specific measure. All of the Company's fixed income securities are priced using a variety of daily data sources, largely readily-available market data and broker quotes. To validate these prices, the Company compares the fair market values of the Company's fixed income investments using market data from observable and corroborated sources. The Company also performs the fair value calculations for its common stock and mutual fund securities using market data from observable and corroborated sources. In periods of market inactivity, the observability of prices and inputs may be reduced for certain instruments. This condition could cause an instrument to be reclassified from Level 1 to Level 2 or from Level 2 to Level 3. During the six months ended June 30, 2014, none of the Company's instruments were reclassified between Level 1, Level 2, Level 3 and there have been no changes in valuation techniques. Also, as of June 30, 2014, all investments have been sold and the remaining fair value is zero.

The following table presents the financial instruments related to the Company’s available-for-sale investment carried at fair value on a recurring basis as of December 31, 2013 by ASC 820-10 valuation hierarchy (as defined above).

⁽¹⁾  Changes in the fair value of available-for-sale investments are recorded in accumulated other comprehensive income, a component of stockholders’ equity, in the Company’s unaudited condensed consolidated balance sheets.

The carrying amounts reflected in the Company's unaudited condensed consolidated balance sheets for cash, accounts receivable - trade, prepaid expenses and other current assets, accounts payable, accrued liabilities, and capital lease obligations approximate fair value due to their short-term nature and the Company valuation techniques use Level 3 inputs. The fair value of the Company's term loan and revolving lines of credit have been estimated by management based on the terms that it believes it could obtain in the current market for debt of the same terms and similar remaining maturities. Due to the short-term nature of the remaining maturities, recent issuances, frequency of amendments to its terms and the variable interest rates, the carrying value of the term loan and revolving lines of credit approximate fair value at June 30, 2014 and December 31, 2013 and the Company's valuation techniques use Level 3 inputs.

10. Notes Payable and Credit Arrangements

Prior to their expiration on April 30, 2014, the Company had two separate credit facilities with Silicon Valley Bank (the “Bank” or “SVB”): (i) a Second Amended and Restated Loan and Security Agreement (as amended, the "Revolving Credit Facility") and (ii) an Amended and Restated Export-Import Bank Loan and Security Agreement (as amended, the "Ex-Im Facility") pursuant

- 12-

to which outstanding amounts under this facility were guaranteed by the Export-Import Bank of the United States (the “EXIM Bank”). The credit facilities provided an aggregate amount of $1.5 million under both facilities, with up to $1.0 million under the Revolving Credit Facility and up to $1.5 million under the Ex-Im Facility. Under the credit facilities, interest on outstanding borrowings accrued at a rate per annum equal to the greater of (i) the prime rate plus 2.5% or (ii) 7.0%. The entire amount owed under the credit facilities was repaid by April 30, 2014.

N2 Bio has two separate agreements under one credit facility with Middlesex Savings Bank (“MSB”): (i) a Secured Term Loan and (ii) a Secured Revolving Demand Note. Under the Secured Term Loan, N2 Bio borrowed $6.0 million on September 18, 2013 to finance the purchase of the Bio Business Unit from the Company. The advance made under the Secured Term Loan will bear interest at a fixed rate of 4.5% per annum in eighty-four (84) consecutive monthly payments starting on October 18, 2013. If not sooner paid, the Secured Term Loan shall be due and payable in full on September 18, 2020. The Secured Revolving Demand Note provides an amount available of up to $1.0 million. Advances made under the Secured Revolving Demand Note will bear interest at MSB's prime rate, as determined, plus 0.5% per annum but in no event shall the interest rate be less than 3.75% per annum. The maturity date of the Secured Revolving Demand Note is May 31, 2015.

N2 Bio's obligations under the credit facility are secured by substantially all of the assets of N2 Bio. Advances under the Secured Revolving Demand Note are limited to 75% of eligible receivables. In addition, until all amounts under the credit facility with MSB are repaid, covenants under the credit facility impose restrictions on the N2 Bio's ability to, among other things, incur additional indebtedness, create or permit liens on the N2 Bio's assets, merge, consolidate or dispose of assets (other than in the ordinary course of business), make dividend and other restricted payments, make certain debt or equity investments, make certain acquisitions, engage in certain transactions with affiliates or change the business conducted by the N2 Bio. Any failure by N2 Bio to comply with the covenants and obligations under the credit facility could result in an event of default, in which case MSB may be entitled to declare all amounts owed to be due and payable immediately.

Advances outstanding under the Revolving Credit Facility were zero and $107 thousand at June 30, 2014 and December 31, 2013, respectively.  Advances outstanding under the Ex-Im Facility were zero and $38 thousand at June 30, 2014 and December 31, 2013, respectively.  Advances outstanding under the N2 Bio Secured Term Loan were $5.4 million and $5.8 million at June 30, 2014 and December 31, 2013, respectively. Advances outstanding under the N2 Bio Secured Revolving Demand Note were $1 thousand and $438 thousand at June 30, 2014 and December 31, 2013, respectively. The interest rate per annum on the N2 Bio Secured Term Loan and Secured Revolving Demand Note on June 30, 2014 was 4.5% and 3.75%, respectively. Availability under the Secured Revolving Demand Note was $537 thousand as of June 30, 2014.

The Company has outstanding letters of credit to secure performance obligations and purchase commitments. Holders of the letters of credit are allowed to draw funds up to the face amount of the letter of credit if the Company does not perform as contractually required.  The outstanding letters of credit are secured by restricted cash. Outstanding letters of credit totaled $666 thousand and $170 thousand at June 30, 2014 and December 31, 2013, respectively.

11. Share-Based Compensation

The Company has recognized share-based compensation expense of approximately $31 thousand and $77 thousand for the six months ended June 30, 2014 and 2013, respectively. The total non-cash, share-based compensation expense included in the unaudited condensed consolidated statements of operations for the periods presented is included in the following expense categories:

	Three Months Ended June 30,				Six Months Ended June 30,
(in thousands)	2014		2013		2014		2013
Cost of contract research, services	$	—	$	5	$	—	$	10
Cost of goods sold	—		4		—		7
Administrative and selling	23		32		31		60
Total share-based compensation	$	23	$	41	$	31	$	77

No share-based compensation expense was capitalized during the six months ended June 30, 2014 and 2013. Compensation expense related to stock options to be charged in future periods amounts to approximately $3 thousand at June 30, 2014 and will be recognized over a weighted-average period of 0.10 years as follows:

- 13-

For the years ended December 31,	Expected Compensation Expense
	(in thousands)
2014	$	3
	$	3

The Company estimates forfeitures at the time of grant and revises, if necessary, in subsequent periods if actual forfeitures differ from those estimates in order to derive the Company’s best estimate of awards ultimately expected to vest.  Forfeitures represent only the unvested portion of a surrendered option and are typically estimated based on historical experience.

At June 30, 2014, the Company had outstanding options under two option plans: the 1996 Equity Incentive Plan (the “1996 Plan”) and the 2007 Stock Equity Plan (the “2007 Plan”, together with the 1996 Plan, the “Plans”).  Both Plans were approved by stockholders and provided that the Board of Directors may grant options to purchase the Company’s common stock to key employees and directors of the Company.  Incentive and non-qualified options must be granted at least at the fair market value of the common stock or, in the case of certain optionees, at 110% of such fair market value at the time of grant. The options may be exercised, subject to certain vesting requirements, for periods up to ten years from the date of issue.  The 1996 Plan expired with respect to the issuance of new grants as of December 10, 2006.  Accordingly, future grants may be made only under the 2007 Plan.

A summary of options outstanding under the Plans as of June 30, 2014 and changes during the six-month period ended June 30, 2014 is as follows:

	Number of Shares		Weighted-Average Exercise Price		Average Remaining Contractual Life (Years)	Aggregate Intrinsic Value (in thousands)
Options Outstanding at December 31, 2013	527,246		$	5.88
Granted	24,000		$	0.85
Exercised	—		$	—
Cancelled/expired	(8,124	)	$	6.24
Options outstanding at June 30, 2014	543,122		$	5.65	4.95	$	7
Options vested and exercisable at June 30, 2014	530,622		$	5.69	4.92	$	7
Option vested and expected to vest at June 30, 2014	542,678		$	5.68	4.93	$	13
Options available for future grant at June 30, 2014	459,759

The aggregate intrinsic value in the table above represents the total intrinsic value, based on the Company’s closing stock price of $0.65 as of June 30, 2014, which would have been received by the option holders had all option holders exercised their options as of that date. The total intrinsic value of options exercised was approximately zero and zero for the six months ended June 30, 2014 and 2013, respectively. The total intrinsic value of options expected to vest at June 30, 2014 was approximately zero, and the weighted average remaining contractual life of outstanding options that are expected to vest is 5.1 years.

The per-share weighted-average fair value of stock options granted during the three and six months ended June 30, 2014 was $0.68 and $0.85, respectively, and $0.58 and $0.58 for the three and six months ended June 30, 2013, respectively, on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions:

Period	Expected Dividend Yield	Risk-Free Interest Rate	Expected Option Life	Expected Volatility Factor
Three Months Ended June 30, 2014	—	1.70%	5.1 years	120.2%
Six Months Ended June 30, 2014	—	1.61%	5.1 years	104.6%
Three Months Ended June 30, 2013	—	0.77%	5.1 years	99.7%
Six Months Ended June 30, 2013	—	0.77%	5.1 years	99.7%

The risk free interest rate reflects treasury yields rates over a term that approximates the expected option life. The expected option life is calculated based on historical lives of all options issued under the Plans.  The expected volatility factor is determined by measuring the actual stock price volatility over a term equal to the expected useful life of the options granted.

13. Variable Interest Entity

The Company has interests in N2 Bio which is a variable interest entity (“VIE”). A VIE is an entity that lacks one or more of the following characteristics (i) the total equity investment at risk is sufficient to enable the entity to finance its activities independently and (ii) the equity holders have the power to direct the activities of the entity that most significantly impact its economic performance, the obligation to absorb the losses of the entity and the right to receive the residual returns of the entity. If the Company is the primary beneficiary of a VIE, the Company is required to consolidate it. To determine if the Company is the primary beneficiary, the Company evaluates whether the Company has the power to direct the activities that most significantly impact the VIE's economic performance and the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. The Company's evaluation includes identification of significant activities and an assessment of the Company's ability to direct those activities based on governance provisions and arrangements to provide or receive product and process technology, product supply, operations services, equity funding, financing and other applicable agreements and circumstances. The Company's assessments of whether the Company is the primary beneficiary of its VIE require significant assumptions and judgments and are reviewed on an ongoing basis based on current facts and circumstances.

On September 18, 2013, the Company, Spire Biomedical, Inc. (the “Subsidiary” and together with the Company, “Spire Bio”) entered into an Asset Purchase Agreement (the “Purchase Agreement”) with N2 Bio pursuant to which N2 Bio agreed to (i) acquire substantially all of the assets of Spire Bio's biomedical business (the “Bio Business Unit”) and (ii) assume and pay certain liabilities related to the purchased assets as set forth in the Purchase Agreement (collectively, the “Transaction”). The Transaction closed on September 18, 2013. The purchase price for the Bio Business Unit was $10.5 million plus the assumption of liabilities of approximately $100 thousand, with $6.0 million paid in cash at closing, a $2.4 million subordinated convertible promissory note, and 310,549 Series A Convertible Preferred Units of N2 Bio valued at approximately $2.1 million ($6.72 per share). The assets and liabilities of the Subsidiary's biomedical business are under common control and were recorded at carryover basis for financial reporting. The difference between the consideration paid and the carrying value of the assets and liabilities acquired by N2 Bio was recorded as a deemed dividend to the Company in the amount of $9.5 million and has been eliminated in consolidation. Mark C. Little was the Chief Executive Officer of the Subsidiary, is a director of the Company and is the Chief Executive Officer of N2 Bio. Mark C. Little is the son of Roger G. Little, Chairman of the Board of Directors of the Company. Roger G. Little is also a member of the Board of Directors of N2 Bio.

On September 18, 2013, N2 Bio entered into a Lease Agreement (the “N2 Bio Bedford Lease”) with SPI-Trust with respect to 27 thousand square feet of space which represents approximately 19% of space in the Bedford, Massachusetts premises. The term of the N2 Bio Bedford Lease commenced on September 18, 2013 and is set to expire on November 30, 2020. The annual

- 15-

rental rate prorated for September 18, 2013 to November 30, 2013 is $16.00 per square foot on a triple net basis, whereby the tenant is responsible for operating expenses, taxes and maintenance of the building. The annual rental rate increases on December 1, 2013 and each anniversary thereafter by $0.50 per square foot.

On September 18, 2013, the Company and N2 Bio entered into a Shared Services Agreement whereby the Company will provide N2 Bio certain services (the “Shared Services”) for a period of three years. It is the intent of the parties that the aggregate fees for the Shared Services shall equal approximately $500 thousand during the first year. Following the first anniversary, N2 Bio may terminate any specific Shared Service with 20 days' written notice to the Company.

The Company has determined that N2 Bio is a VIE because the equity investment at risk from the majority shareholders of N2 Bio is not sufficient to permit N2 Bio to finance its activities without additional subordinated financial support. As discussed above, N2 Bio is subject to a subordinated convertible promissory note due to the Company. The assets of N2 Bio can only be used to settle the obligations of N2 Bio and there is no recourse to the Company related to the third party obligations of or third party arrangements entered into by N2 Bio. Additionally, Mark Little is the Chief Executive Officer of N2 Bio and also a member the Company's Board of Directors. The Company has also determined that the Company has the obligation to absorb losses and the right to receive benefits from N2 Bio that could potentially be significant to it. Therefore, the Company has determined that N2 Bio is a VIE and that the Company is a primary beneficiary of the VIE and must consolidate the financial condition, results of operations and cash flows of N2 Bio with those of its own.

The assets and liabilities from the VIE included in the condensed consolidated balance sheets as of June 30, 2014 and December 31, 2013 are as follows:

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

This Management’s Discussion and Analysis of Financial Condition and Results of Operations section and other parts of this Report contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which statements involve risks and uncertainties. These statements relate to our future plans, objectives, expectations and intentions. These statements may be identified by the use of words such as “may”, “could”, “would”, “should”, “will”, “expects”, “anticipates”, “intends”, “plans”, “believes”, “estimates”, and similar expressions. Our actual results and the timing of certain events may differ significantly from the results and timing described in the forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those factors discussed or referred to in the Annual Report on Form 10-K for the year ended December 31, 2013 and in subsequent periodic reports filed with the Securities and Exchange Commission, including this report. The following discussion and analysis of our financial condition and results of operations should be read in light of those factors and in conjunction with our accompanying Consolidated Financial Statements, including the Notes thereto.

Overview

We and our subsidiaries along with our variable interest entity develop, manufacture and market highly-engineered products and services in two principal business areas: (i) capital equipment for the photovoltaic solar industry and (ii) biomedical, through our variable interest entity, N2 Biomedical LLC ("N2 Bio"), generally bringing to bear expertise in materials technologies, surface science and thin films across both business areas, as discussed below.

In the photovoltaic solar area, we develop, manufacture and market specialized equipment for the production of terrestrial photovoltaic modules from solar cells.  Our equipment has been installed in approximately 200 factories in 50 countries.  The equipment market is very competitive with major competitors located in the U.S., Japan and Europe.  Our flagship product is our Spi-Sun simulator which tests module performance.  Our other product offerings include turn-key module lines and to a lesser extent other individual equipment.  To compete we offer other services such as training and assistance with module certification.  We also provide turn-key services to our customers to backward integrate to solar cell manufacturing.

In the biomedical area, through our variable interest entity, N2 Bio, we provide value-added surface treatments to manufacturers of orthopedic and other medical devices that enhance the durability, antimicrobial characteristics or other material characteristics of their products, and perform sponsored research programs into practical applications of advanced biomedical technologies.

Operating results will depend upon revenue growth or decline and product mix, as well as the timing of shipments of higher priced products from our solar equipment line.  Export sales, which amounted to 41% and 34% of net sales and revenues for the six months ended June 30, 2014 and 2013, respectively, continue to constitute a significant portion of our net sales and revenues.

The following table sets forth certain items as a percentage of net sales and revenues for the periods presented:

	Three Months Ended June 30,				Six Months Ended June 30,

Overall

Our total net sales and revenues for the six months ended June 30, 2014 were $7.9 million as compared to $6.8 million for the six months ended June 30, 2013, which represents an increase of $1.1 million or 16%. The increase was primarily attributable to a $1.1 million increase in solar revenue along with a slight increase in biomedical revenue.

Solar Business Unit

Sales in our solar business unit increased 32% during the six months ended June 30, 2014 to $4.4 million as compared to $3.3 million for the six months ended June 30, 2013. The increase in solar business unit revenue is primarily the result of an increase in equipment research and development revenue of $801 thousand and an increase in solar module equipment revenue of $627 thousand, partially offset by a decrease in solar research and development revenue of $344 thousand. Lower government incentives in the photovoltaic market and the world-wide oversupply of photovoltaic modules relative to market demand has led to precipitously declining prices in the photovoltaic market. The oversupply has also resulted in reduced demand for photovoltaic manufacturing equipment that will not improve until the module supply/demand imbalance is rectified via the growing photovoltaic systems market. Our Solar Business Unit has been negatively impacted by this reduction in demand.

Biomedical Business Unit

Revenues from the biomedical business increased 2% during the six months ended June 30, 2014 to $3.5 million as compared to $3.5 million for the six months ended June 30, 2013.  The increase was primarily attributable to an increase in revenue from the orthopedics coating services, partially offset by a decrease in revenue from our research and development contracts.

Net Sales and Revenues

The following table categorizes our net sales and revenues for the periods presented:

- 19-

	Three Months Ended June 30,				Increase (Decrease)
(in thousands)	2014		2013		$			%
Sales of goods	$	1,850	$	1,467	$	383		26	%
Contract research and services revenues	1,995		2,107		(112		)	(5	)%
Net sales and revenues	$	3,845	$	3,574	$	271		8	%

The 26% increase in sales of goods for the three months ended June 30, 2014 as compared to the three months ended June 30, 2013 was primarily due to an increase of $392 thousand in solar module manufacturing equipment, partially offset by a decrease of $8 thousand in ATC Lab revenues. The increase in solar module equipment sales of 27% in 2014 as compared to 2013 was primarily due to an increase in individual module equipment units delivered in 2014. The decrease in ATC Lab revenue in 2014 as compared to 2013 was primarily due to a reduction in the number of projects completed in 2014. Lower government incentives in the photovoltaic market and the world-wide oversupply of photovoltaic modules relative to market demand has led to precipitously declining prices in the photovoltaic market. The oversupply has also resulted in reduced demand for photovoltaic manufacturing equipment that will not improve until the module supply/demand imbalance is rectified via the growing photovoltaic systems market. Our Solar Business Unit has been negatively impacted by this reduction in demand.

The 5% decrease in contract research and services revenues for the three months ended June 30, 2014 as compared to the three months ended June 30, 2013 is primarily attributable to a decrease of $195 thousand research and development revenue, partially offset by an increase of $83 thousand in biomedical service revenue. The decrease in research and development revenue of 39% in 2014 as compared to 2013 was primarily due to the completion of projects in 2013 that were not replaced in 2014. Revenues from our biomedical services increased 5% in 2014 as compared to 2013 as a result of an increase in revenue from a large customer in 2014.

The following table categorizes our net sales and revenues for the periods presented:

	Six Months Ended June 30,				Increase
(in thousands)	2014		2013		$		%
Sales of goods	$	3,039	$	2,437	$	602	25	%
Contract research and services revenues	4,892		4,375		517		12	%
Net sales and revenues	$	7,931	$	6,812	$	1,119	16	%

The 25% increase in sales of goods for the six months ended June 30, 2014 as compared to the six months ended June 30, 2013 was primarily due to an increase of $627 thousand in solar module manufacturing equipment, partially offset by a decrease of $20 thousand in ATC Lab revenues. The increase in solar module equipment sales of 26% in 2014 as compared to 2013 was primarily due to an increase in individual module equipment units delivered in 2014. The decrease in ATC Lab revenue of 63% in 2014 as compared to 2013 was primarily due to a reduction in the number of projects completed in 2014. Lower government incentives in the photovoltaic market and the world-wide oversupply of photovoltaic modules relative to market demand has led to precipitously declining prices in the photovoltaic market. The oversupply has also resulted in reduced demand for photovoltaic manufacturing equipment that will not improve until the module supply/demand imbalance is rectified via the growing photovoltaic systems market. Our Solar Business Unit has been negatively impacted by this reduction in demand.

The 12% increase in contract research and services revenues for the six months ended June 30, 2014 as compared to the six months ended June 30, 2013 is primarily attributable to an increase of $801 thousand in equipment research and development revenue and an increase of $159 thousand in biomedical service revenue, partially offset by a decrease of $344 thousand in solar research and development revenue and a decrease of $100 thousand in biomedical research and development revenue. The increase in equipment research and development revenue of 159% in 2014 as compared to 2013 was primarily due to the completion of a large project in 2014. Revenues from our biomedical services increased 5% in 2014 as compared to 2013 as a result of an increase in revenue from a large customer in 2014. The decrease in solar research and development revenue of 87% in 2014 as compared to 2013 was primarily due to the completion of two research and development projects in 2013. The decrease in biomedical research and development revenue of 100% in 2014 as compared to 2013 was primarily due to the completion of ten research and development projects in 2013 and no research and development projects undertaken in 2014.

Cost of Sales and Revenues

The following table categorizes our cost of sales and revenues for the periods presented, stated in dollars and as a percentage of related sales and revenues:

Net cost of sales and revenues	$	6,730	85	%	$	6,074	89	%	$	656	11	%

Cost of goods sold increased 4% for the six months ended June 30, 2014 as compared to the six months ended June 30, 2013, primarily due to an increase of $251 thousand in costs related to solar module equipment, partially offset by a decrease of $119 thousand in costs related to solar systems. The increase in solar module equipment costs of 7% in 2014 as compared to 2013 was primarily due to an increase in associated revenue. The decrease in solar system costs of 100% in 2014 as compared to 2013 was primarily due to no active projects in 2014. As a percentage of sales, cost of goods sold decreased to 126% of sales of goods in 2014 as compared to 152% of sales of goods in 2013. This decrease in the percentage of sales in 2014 is due primarily to the delivery of higher margin solar module manufacturing equipment in 2014.

Cost of contract research and services increased 21% for the six months ended June 30, 2014 as compared to the six months ended June 30, 2013, primarily due to an increase of $925 thousand in costs related to equipment research and development services, partially offset by a decrease of $204 thousand in costs related to biomedical research and development services and $152 thousand in costs related to solar research and development services. The increase in equipment research and development services costs in 2014 was primarily due to the completion of a large project in 2014. The decrease in biomedical research and development services costs of 100% in 2014 as compared to 2013 was due to no active projects being worked on in 2014. The decrease in solar research and development services costs of 78% in 2014 as compared to 2013 was primarily due to the completion of two projects in 2013. Cost of contract research and services as a percentage of related revenue increased to 59% of related revenues in 2014 from 54% in 2013. This increase in the percentage of sales in 2014 is primarily due to lower margin from the completion of a large equipment research and development project in the first quarter of 2014.

Selling, General and Administrative Expenses

Selling, general and administrative expense decreased 25% in the three months ended June 30, 2014 as compared to the three months ended June 30, 2013, primarily as a result of an increased benefit of approximately $632 thousand related to the change in value, including realized gains, of the deferred compensation plan and a decrease in employee related expenses of approximately $94 thousand due to a reduction in workforce. These amounts were partially offset by an increase in legal costs of approximately $254 thousand. Income of approximately $765 thousand was realized related to the change in value of the deferred compensation plan and realized gains on the sale of available-for-sale investments for the three months ended June 30, 2014. Selling, general and administrative expense decreased to 44% of sales and revenues in 2014 as compared to 64% in 2013.  The decrease was primarily due to the increase in sales and revenues and decreased expenses related to the deferred compensation plan.

Selling, general and administrative expenses include approximately $23 thousand and $32 thousand of share-based compensation for the three months ended June 30, 2014 and 2013, respectively.

Internal Research and Development

Internal research and development expense decreased 50% in the three months ended June 30, 2014 as compared to the three months ended June 30, 2013, primarily as a result of slightly lower levels of research and development spent in the solar group.  As a percentage of sales and revenue, internal research and development expenses decreased slightly in 2014 when compared to 2013.

The following table categorizes our operating expenses for the periods presented, stated in dollars and as a percentage of total sales and revenues:

Selling, general and administrative expenses include approximately $31 thousand and $60 thousand of share-based compensation for the six months ended June 30, 2014 and 2013, respectively.

Internal Research and Development

Internal research and development expense increased 17% in the six months ended June 30, 2014 as compared to the six months ended June 30, 2013, primarily as a result of slightly higher levels of research and development spent in the solar group.  As a percentage of sales and revenue, internal research and development expenses remained constant in 2014 when compared to 2013.

Other Expense, Net

We incurred interest expense, net of $70 thousand and $13 thousand for the three months ended June 30, 2014 and 2013, respectively.  The increase in interest expense is due to increased debt related to the term note with Middlesex Savings Bank retained in the third quarter of 2013. We had nominal currency exchange losses during the three months ended June 30, 2014 and 2013.

We incurred interest expense, net of $145 thousand and $29 thousand for the six months ended June 30, 2014 and 2013, respectively.  The increase in interest expense is due to increased debt related to the term note with Middlesex Savings Bank retained in the third quarter of 2013. We had nominal currency exchange losses during the six months ended June 30, 2014 and 2013.

Income Taxes

We recorded a state income tax provision of $2 thousand and zero during the three months ended June 30, 2014 and 2013, respectively. We recorded a state income tax provision of $2 thousand and $2 thousand during the six months ended June 30, 2014 and 2013, respectively. Gross federal net operating loss carryforwards were approximately $13.9 million as of December 31, 2013 and expire at various times through 2033. We have a full valuation allowance recorded against the net deferred tax assets at June 30, 2014 due to uncertainty regarding realization of these assets in the future.

Net Loss

We reported net loss of $1.1 million and $1.8 million for the three months ended June 30, 2014 and 2013, respectively. Net loss decreased approximately $705 thousand, primarily due to a $566 thousand decrease in operating expenses and improved margin in solar module manufacturing equipment and biomedical services of $155 thousand and $102 thousand, respectively, partially offset by a $57 thousand increase in interest expense, net.

We reported net loss of $3.8 million and $4.4 million for the six months ended June 30, 2014 and 2013, respectively. Net loss decreased approximately $629 thousand, primarily due to improved margin in solar module manufacturing equipment and biomedical services of $376 thousand and $223 thousand, respectively, and a decrease of $275 thousand in operating expenses, partially offset by decreased margin in solar research and development of $192 thousand and a $116 thousand increase in interest expense, net.

Net Income Attributable to Noncontrolling Interest

We reported a net income attributable to noncontrolling interest of $360 thousand and zero for three months ended June 30, 2014 and 2013, respectively. We reported a net income attributable to noncontrolling interest of $778 thousand and zero for six months ended June 30, 2014 and 2013, respectively. Net income attributable to noncontrolling interest represents 80.1% of N2 Bio's net income for the three and six months ended June 30, 2014.

Net Loss Attributable to Common Stockholders

We reported net loss attributable to common stockholders of $1.4 million and $1.8 million for the three months ended June 30, 2014 and 2013, respectively. Net loss attributable to common stockholders decreased approximately $345 thousand, primarily due to a $566 thousand decrease in operating expenses and improved margin in solar module manufacturing equipment and biomedical services of $155 thousand and $102 thousand, respectively, partially offset by a reduction in net income attributable to noncontrolling interest of $360 thousand and a $57 thousand increase in interest expense, net.

- 23-

We reported net loss attributable to common stockholders of $4.6 million and $4.4 million for the six months ended June 30, 2014 and 2013, respectively. Net loss attributable to common stockholders increased approximately $149 thousand, primarily due to a reduction in net income attributable to noncontrolling interest of $778 thousand, decreased margin in solar research and development of $192 thousand and a $116 thousand increase in interest expense, net, partially offset by improved margin in solar module manufacturing equipment and biomedical services of $376 thousand and $223 thousand, respectively, and a decrease of $275 thousand in operating expenses.

Liquidity and Capital Resources

	June 30,			December 31,		Decrease
(in thousands)	2014			2013		$			%
Cash and cash equivalents	$	985		$	3,986	$	(3,001	)	(75	)%
Working capital	$	(542	)	$	3,704	$	(4,246	)	(115	)%

Cash and cash equivalents decreased due to cash used in operating activities and to a lesser extent cash used in financing and investing activities. The overall decrease in working capital is due to a decrease in current assets, primarily cash, available-for-sale investments, deferred cost of goods sold and prepaid expenses and other current assets along with an increase in accounts payable and advances on contracts in progress. We have historically funded our operating cash requirements using operating cash flow, proceeds from the sale and licensing of technology and assets and proceeds from the sale of equity securities.

There are no material commitments by us for capital expenditures. At June 30, 2014, our accumulated deficit was approximately $29.0 million, compared to accumulated deficit of approximately $24.4 million as of December 31, 2013.

Operating results will depend upon revenue growth or decline and product mix, as well as the timing of shipments of higher priced products from our solar equipment line and delivery of research and development services.  Export sales, which amounted to 41% and 34% of net sales and revenues for the six months ended June 30, 2014 and 2013, respectively, continue to constitute a significant portion of our net sales and revenues.

Net cash used in operating activities was $1.9 million for the six months ended June 30, 2014, which includes proceeds of $3.9 million from the sale of available-for-sale investments, offset by deferred compensation payments of $3.9 million. Net cash used in operating activities was $1.9 million for the six months ended June 30, 2013, which includes $150 thousand of cash used in operating activities of discontinued operations. As of June 30, 2014, we had unrestricted cash and cash equivalents of $1.0 million compared to $4.0 million as of December 31, 2013.

We currently believe that our existing cash resources at June 30, 2014, will be sufficient to fund our operations into the second half of 2014; however, we cannot provide any assurances of our continued operations and liquidity. The Revolving Credit Facility and the Ex-Im Facility with Silicon Valley Bank expired on April 30, 2014 and will not be renewed. As a result, in our Annual Report on Form 10-K for the year ended December 31, 2013, our independent registered public accounting firm expressed a substantial doubt about our ability to continue as a going concern in their report on our consolidated financial statements dated March 31, 2014.

We have various options on how to fund future operational losses or working capital needs, including but not limited to sales of equity, bank debt, private lenders, the sale or license of assets and technology, or joint ventures involving cash infusions, as we have done in the past; however, there are no assurances that we will be able to sell equity, obtain or access bank debt or alternative financing, sell or license assets or technology or enter into such joint ventures on a timely basis and at appropriate values or on acceptable terms, if at all. We have developed several plans including potential strategic alternatives, cost reduction efforts and expand revenue in other solar markets to offset a decline in business due to global economic conditions.  Our inability to successfully implement our cost reduction strategies, expand revenue in other solar markets or to replace our expired credit facilities, could adversely impact our ability to continue as a going concern.

The financial statements do not include any adjustments that might be necessary if we are unable to continue as a going concern.

Loan Agreements

Prior to their expiration on April 30, 2014, we had two separate credit facilities with Silicon Valley Bank (the “Bank” or “SVB”): (i) a Second Amended and Restated Loan and Security Agreement (as amended, the “Revolving Credit Facility”) and (ii) an Amended and Restated Export-Import Bank Loan and Security Agreement (as amended, the “Ex-Im Facility”) pursuant to

- 24-

which outstanding amounts under this facility are guaranteed by the Export-Import Bank of the United States (the “EXIM Bank”). The credit facilities provided an aggregate amount of $1.5 million under both facilities, with up to $1 million under the Revolving Credit Facility and up to $1.5 million under the Ex-Im Facility. Under the credit facilities, interest on outstanding borrowings accrued at a rate per annum equal to the greater of (i) the prime rate plus 2.5% or (ii) 7.0%. The entire amount owed under the credit facilities was repaid by April, 30, 2014.

N2 Bio has two separate agreements under one credit facility with Middlesex Savings Bank (“MSB”): (i) a Secured Term Loan and (ii) a Secured Revolving Demand Note. Under the Secured Term Loan, N2 Bio borrowed $6.0 million on September 18, 2013 to finance the purchase of the Bio Business Unit from the Company. The advance made under the Secured Term Loan will bear interest at a fixed rate of 4.5% per annum in eighty-four (84) consecutive monthly payments starting on October 18, 2013. If not sooner paid, the Secured Term Loan shall be due and payable in full on September 18, 2020. The Secured Revolving Demand Note provides an amount available of up to $1.0 million. Advances made under the Secured Revolving Demand Note will bear interest at MSB's prime rate, as determined, plus 0.5% per annum but in no event shall the interest rate be less than 3.75% per annum. The maturity date of the Secured Revolving Demand Note is May 31, 2015.

N2 Bio's obligations under the credit facility, is secured by substantially all of the assets of N2 Bio. Advances under the Secured Revolving Demand Note are limited to 75% of eligible receivables. In addition, until all amounts under the credit facility with MSB are repaid, covenants under the credit facility impose restrictions on the N2 Bio's ability to, among other things, incur additional indebtedness, create or permit liens on the N2 Bio's assets, merge, consolidate or dispose of assets (other than in the ordinary course of business), make dividend and other restricted payments, make certain debt or equity investments, make certain acquisitions, engage in certain transactions with affiliates or change the business conducted by the N2 Bio. Any failure by N2 Bio to comply with the covenants and obligations under the credit facility could result in an event of default, in which case MSB may be entitled to declare all amounts owed to be due and payable immediately.

Advances outstanding under the Revolving Credit Facility were zero and $107 thousand at June 30, 2014 and December 31, 2013, respectively.  Advances outstanding under the Ex-Im Facility were zero and $38 thousand at June 30, 2014 and December 31, 2013, respectively.  Advances outstanding under the N2 Bio Secured Term Loan were $5.4 million and $5.8 million at June 30, 2014 and December 31, 2013, respectively. Advances outstanding under the N2 Bio Secured Revolving Demand Note were $1 thousand and $438 thousand at June 30, 2014 and December 31, 2013, respectively. The interest rate per annum on the N2 Bio Secured Term Loan and Secured Revolving Demand Note on June 30, 2014 was 4.5% and 3.75%, respectively. Combined availability under the Secured Revolving Demand Note was $537 thousand as of June 30, 2014.

Net Cash Used in Operating Activities

Net cash used in operating activities was $1.9 million for the six months ended June 30, 2014. Net cash used in operating activities was $1.9 million for the six months ended June 30, 2013, which includes $150 thousand of cash used in operating activities of discontinued operations. As of June 30, 2014, we had unrestricted cash and cash equivalents of $1.0 million compared to $4.0 million as of December 31, 2013.

Foreign Currency Fluctuation

We sell almost exclusively in U.S. dollars, generally against an irrevocable non-transferable confirmed letter of credit through a major United States bank. Accordingly, we are not directly affected by foreign exchange fluctuations on our current sales orders. However, fluctuations in foreign exchange rates do have an effect on our customers' access to U.S. dollars and on the pricing competition on certain pieces of equipment that we sell in selected markets. We bear the risk of any currency fluctuations that may be associated with these commitments. We attempt to hedge known transactions when possible to minimize foreign exchange risk. We had no hedging activity during the first six months of 2014 and 2013. Foreign exchange loss included in other expense, net, was nominal during the three and six months ended June 30, 2014 and 2013.

Related Party Transactions

On November 30, 2007, we entered into a new Lease Agreement (the “Bedford Lease”) with SPI-Trust, a trust of which Roger G. Little, Chairman of the Board of the Company, is the sole trustee and principal beneficiary, with respect to 144,230 square feet of space comprising the entire building in which we have occupied space since December 1, 1985. The term of the Bedford Lease commenced on December 1, 2007 and was originally set to expire on November 30, 2012. The annual rental rate for the first year of the Bedford Lease was $12.50 per square foot on a triple net basis, whereby the tenant is responsible for operating expenses, taxes and maintenance of the building. The annual rental rate increased on each anniversary by $0.75 per square foot.

- 25-

On September 17, 2010, we entered into the First Amendment to Lease Agreement with SPI-Trust to amend the Bedford Lease. The term of the Bedford Lease was extended for an additional five (5) years to expire on November 30, 2017. The annual rental rate for the first year of the extended term (December 1, 2012 through November 30, 2013) is $16.00 per square foot on a triple net basis, whereby the tenant is responsible for operating expenses, taxes and maintenance of the building. After the first year of the extended term of the Bedford Lease, the annual rental rate increases on each anniversary by $0.50 per square foot. We have the right to further extend the term of the Bedford Lease for an additional five (5) year period. If we exercise this right to further extend the term of the Bedford Lease, the annual rental rate for the first year of the further extended term will be the greater of: (a) the rental rate in effect immediately preceding the commencement of the extended term; or (b) the market rate at such time, and on each anniversary of the commencement of the extended term the rental rate will increase by $0.50 per square foot. Additionally, SPI-Trust agreed to reimburse us up to $50 thousand for all costs incurred by us in connection with any alterations or improvements to the premises or repairs or replacements to the heating and air conditioning systems.

On September 18, 2013, we entered into the Second Amendment to Lease Agreement with SPI-Trust to amend the Bedford Lease. The leased portion of the premises and annual base rent in Bedford, Massachusetts was reduced by approximately 19%. All other material terms and conditions related to the lease remain unchanged as of such date. We believe that the terms of the Bedford Lease, as amended, are commercially reasonable. Rent expense under the Bedford Lease was $390 and $578 thousand for the three months ended June 30, 2014 and 2013, respectively, and $779 thousand and $1.2 million for the six months ended June 30, 2014 and 2013, respectively.

On September 18, 2013, N2 Bio entered into a Lease Agreement (the “N2 Bio Bedford Lease”) with SPI-Trust with respect to 27 thousand square feet of space in the premises in Bedford, Massachusetts. The term of the N2 Bio Bedford Lease commenced on September 18, 2013 and is set to expire on November 30, 2020. The annual rental rate prorated for September 18, 2013 to November 30, 2013 is $16.00 per square foot on a triple net basis, whereby the tenant is responsible for operating expenses, taxes and maintenance of the building. The annual rental rate increases on December 1, 2013 and each anniversary thereafter by $0.50 per square foot. We believe that the terms of the N2 Bio Bedford Lease are commercially reasonable. Rent expense under the N2 Bio Bedford Lease was $121 thousand and $243 thousand for the three and six months ended June 30, 2014, respectively.

Critical Accounting Policies

The preparation of financial statements in accordance with accounting principles generally accepted in the United States requires us 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 revenues and expenses during the reporting period. Among the significant estimates affecting our condensed consolidated financial statements are those relating to revenue recognition, reserves for doubtful accounts, reserve for excess and obsolete inventory, impairment of long-lived assets, share-based compensation and warranty reserves. We regularly evaluate our estimates and assumptions based upon historical experience and various other factors that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. To the extent actual results differ from those estimates, our future results of operations may be affected. We believe the critical accounting policies affect our more significant judgments and estimates used in the preparation of our condensed consolidated financial statements. A summary of significant accounting policies and a description of accounting policies that are considered critical may be found in our Annual Report on Form 10-K for the year ended December 31, 2013, in Note 2 of the notes to consolidated financial statements and the Critical Accounting Policies section of Management's Discussion and Analysis of Financial Condition and Results of Operations.

Contractual Obligations, Commercial Commitments and Off-Balance Sheet Arrangements

The following table summarizes our gross contractual obligations at June 30, 2014 and the maturity periods and the effect that such obligations are expected to have on our liquidity and cash flows in future periods:

- 26-

Purchase obligations include open purchase orders which are firm, non-cancelable and unconditional. Included in purchase obligations are raw material, equipment and services needed to fulfill customer orders.

The Revolving Demand Note does not include an interest component to the contractual obligation.

Outstanding letters of credit totaled $666 thousand and $170 thousand at June 30, 2014 and December 31, 2013, respectively. The letters of credit secure performance obligations and purchase commitments, and allow holders to draw funds up to the face amount of the letter of credit if we do not perform as contractually required.  The outstanding letters of credit are secured by restricted cash.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this report, an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) was performed under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of June 30, 2014 to ensure that information required to be disclosed in the reports we file and 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 information required to be disclosed under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Accounts Receivable and Advances on Contracts in Progress [Abstract]

Accounts Receivables and Advances on Contracts in Progress

Accounts Receivable/Advances on Contracts in Progress

Net accounts receivable, trade and advances on contracts in progress consists of the following:

(in thousands)	June 30, 2014			December 31, 2013
Amounts billed	$	1,383		$	1,396
Accrued revenue	18			18
Gross accounts receivable - trade	1,401			1,414
Less:  Allowance for doubtful accounts	(32		)	—
Net accounts receivable - trade	$	1,369		$	1,414
Advances on contracts in progress	$	1,851		$	1,433

Accrued revenue represents revenues recognized on contracts for which billings have not been presented to customers as of the balance sheet date.

The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to pay amounts due. The Company actively pursues collection of past due receivables as the circumstances warrant. Customers are contacted to determine the status of payment and senior accounting and operations management are included in these efforts as is deemed necessary. A specific reserve will be established for past due accounts when it is probable that a loss has been incurred and the Company can reasonably estimate the amount of the loss. The Company does not record an allowance for government receivables and invoices backed by letters of credit as collection is reasonably assured. Bad debts are written off against the allowance when identified. There is no dollar threshold for account balance write-offs. While rare, a write-off is only recorded when all efforts to collect the receivable have been exhausted.

Advances on contracts in progress represent billings that have been presented to the customer, as either deposits or progress payments against future shipments, but revenue has not been recognized.

Interim Financial Statements [Abstract]

Organization, Consolidation and Presentation of Financial Statements Disclosure

Interim Financial Statements

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission ("SEC") regarding interim financial reporting.  Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted in accordance with such rules and regulations. These unaudited condensed consolidated financial statements should be read in conjunction with the annual audited consolidated financial statements and notes thereto for the year ended December 31, 2013, included in the Company’s Annual Report on Form 10-K filed with the SEC.

In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary to fairly present the Company’s financial position as of June 30, 2014 and December 31, 2013 and the results of operations for the three and six months ended June 30, 2014 and 2013. The results of operations for the three and six months ended June 30, 2014 are not necessarily indicative of the results to be expected for the fiscal year ending December 31, 2014.  The unaudited condensed consolidated balance sheet as of December 31, 2013 has been derived from audited financial statements as of that date.  

Summary of Significant Accounting Policies

With the exception of the Company's revenue recognition policy which has been updated below, the significant accounting policies followed by the Company are set forth in Note 2 to the Company’s consolidated financial statements in its Annual Report on Form 10-K for the year ended December 31, 2013, filed with the SEC on March 31, 2014.

Revenue Recognition

The Company derives its revenues from continuing operations from three primary sources: (1) sales of commercial products including, but not limited to, solar energy manufacturing equipment; (2) biomedical and coating technology services; and (3) United States government funded research and development contracts.

The Company generally recognizes product revenue upon shipment of products provided there are no uncertainties regarding customer acceptance, persuasive evidence of an arrangement exists, the sales price is fixed or determinable, and collectability is reasonably assured. These criteria are generally met at the time of shipment when the risk of loss and title passes to the customer.

The Company's OEM (original equipment manufacturer) capital equipment solar energy business builds complex customized machines to order for specific customers.  Most orders are sold on a FOB Bedford, Massachusetts (or EX-Works Factory) basis and other orders are sold on a Carriage and Insurance Paid (or CIP), or on rare situations, a Delivery Duty Unpaid (or DDU) basis. It is the Company's policy to recognize revenues for this equipment when title of the product has passed to the customer, provided that customer acceptance is obtained prior to shipment and the equipment is expected to operate the same in the customer's environment as it does in the Company's environment.  When an arrangement with the customer includes future obligations or customer acceptance, revenue is recognized when those obligations are met or customer acceptance has been achieved.  Typically, the Company is able to separate arrangements with multiple elements into more than one unit of accounting as it relates to the passage of title to goods, training and installation services when no right of return exists. The Company allocates total fees under contract to each element using the relative selling price method and revenue is recognized upon delivery of each element. The Company's management performs extensive analysis to determine the relative selling price of each unit of accounting. The Company allocates revenue in arrangements using its best estimate of selling price if neither vendor-specific objective evidence ("VSOE") nor third-party evidence (“TPE”) of selling price exists.  The Company determines estimated selling price ("ESP") of each deliverable based on a number of factors, including internal costs, gross margin targetsandhistorical sales of similar units, as well as external factors such as market and competitive conditions.

The Company's biomedical services provides advanced medical device surface treatment processes for performance improvement of orthopedic devices. The Company's coating technology services are provided to both industrial and consumer electronic applications. It is the Company's policy to recognize revenues from these services when services are provided to the customer.

The Company recognizes revenues and estimated profits on long-term government contracts on a percent complete basis where the circumstances are such that total profit can be estimated with reasonable accuracy and ultimate realization is reasonably assured. The Company records revenue and profit utilizing the percentage of completion method using a cost-to-cost methodology. A percentage of the contract revenues and estimated profits is determined utilizing the ratio of costs incurred to date to total estimated cost to complete on a contract by contract basis. Profit estimates are revised periodically based upon changes in facts, and any losses on contracts are recognized immediately. Some of the contracts include provisions to withhold a portion of the contract value as retainage until such time as the United States government performs an audit of the cost incurred under the contract.  The Company's policy is to take into revenue the full value of the contract, including any retainage, as it performs against the contract since the Company has not experienced any substantial losses as a result of audits performed by the United States government.

New Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606). The guidance in this ASU affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards. The guidance in this ASU supersedes the revenue recognition requirements in Accounting Standards Codification ("ASC") No. 605, Revenue Recognition, and most industry-specific guidance throughout the Industry Topics of the Codification. Additionally, this ASU supersedes some cost guidance included in ASC No. 605-35, Revenue Recognition-Construction-Type and Production-Type Contracts. In addition, the existing requirements for the recognition of a gain or loss on the transfer of nonfinancial assets that are not in a contract with a customer are amended to be consistent with the guidance on recognition and measurement in this ASU. For a public entity, the amendments in this ASU are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Retrospective application of the amendments in this ASU are required. The new guidance must be adopted using either a full retrospective approach for all periods presented in the period of adoption (with some limited relief provided) or a modified retrospective approach. Early application is not permitted under GAAP. The Company is currently assessing the impact of this ASU on its unaudited condensed consolidated financial statements.

In July 2013, the FASB issued ASU No. 2013-11 ("ASU 2013-11"), Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. The update requires, unless certain conditions exists, an unrecognized tax benefit, or a portion of an unrecognized tax benefit, to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, similar tax loss, or a tax credit carryforward. ASU 2013-11 is effective prospectively for reporting periods beginning after December 15, 2013, with early adoption permitted. Retrospective application is permitted. The application of this ASU did not have an impact on the Company's unaudited condensed consolidated financial statements.

Description of the Business [Abstract]

Description of the Business

Description of the Business

Spire Corporation ("Spire" or the "Company") and its subsidiaries along with its variable interest entity develop, manufacture and market highly-engineered products and services in two principal business areas: (i) capital equipment for the photovoltaic solar industry and (ii) biomedical, through its variable interest entity, N2 Biomedical LLC ("N2 Bio"), generally bringing to bear expertise in materials technologies, surface science and thin films across both business areas, discussed below.

In the photovoltaic solar area, the Company develops, manufactures and markets specialized equipment for the production of terrestrial photovoltaic modules from solar cells.  The Company's equipment has been installed in approximately 200 factories in 50 countries.  The equipment market is very competitive with major competitors located in the U.S., Japan and Europe.  The Company's flagship product is its Spi-Sun simulator which tests module performance.  The Company's other product offerings include turn-key module lines and to a lesser extent other individual equipment.  To compete the Company offers other services such as training and assistance with module certification.  The Company also provides turn-key services to its customers to backward integrate to solar cell manufacturing.

In the biomedical area, through its variable interest entity, N2 Bio, the Company provides value-added surface treatments to manufacturers of orthopedic and other medical devices that enhance the durability, antimicrobial characteristics or other material characteristics of their products; and performs sponsored research programs into practical applications of advanced biomedical technologies.

Liquidity

Operating results will depend upon revenue growth or decline and product mix, as well as the timing of shipments of higher priced products from the Company's solar equipment line.  Export sales, which amounted to 46% and 41% of net sales and revenues for the three and six months ended June 30, 2014, respectively, and 37% and 34% of net sales and revenues for the three and six months ended June 30, 2013, respectively, continue to constitute a significant portion of the Company's net sales and revenues.

The Company has incurred losses from operations.  Losses from operations were $1.0 million and $3.6 million for the three and six months ended June 30, 2014, respectively. Losses from operations were $1.8 million and $4.4 million for the three and six months ended June 30, 2013, respectively. Net cash used in operating activities was $1.9 million for the six months ended June 30, 2014. Net cash used in operating activities was $1.9 million for the six months ended June 30, 2013, which includes $150 thousand of cash used in operating activities of discontinued operations. As of June 30, 2014, the Company had unrestricted cash and cash equivalents of $1.0 million compared to $4.0 million as of December 31, 2013.  The Company's credit facilities with Silicon Valley Bank expired on April 30, 2014 and will not be renewed, and the Company has repaid the outstanding amounts. These factors raise substantial doubt about the Company's ability to continue as a going concern. The Company currently believes that its existing cash resources at June 30, 2014, will be sufficient to fund its operations into the second half of 2014; however, the Company cannot provide any assurances of its continued operations and liquidity.

The Company has various options on how to fund future operational losses and working capital needs, including but not limited to sales of equity, bank debt, private lenders, the sale or license of assets and technology, or joint ventures involving cash infusions, as it has done in the past; however, there are no assurances that the Company will be able to sell equity, obtain or access bank debt or alternative financing, sell or license assets or technology or enter into such joint ventures on a timely basis and at appropriate values or on acceptable terms, if at all.  The Company has developed several plans including potential strategic alternatives, cost reduction efforts and expanding revenue in other markets to offset a decline in business due to global economic conditions.  The Company's inability to successfully implement its cost reduction strategies, expand revenue in other markets or to replace its expired credit facilities, could adversely impact the Company's ability to continue as a going concern.

The financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern.

Disclosure of Compensation Related Costs, Share-based Payments

Share-Based Compensation

The Company has recognized share-based compensation expense of approximately $31 thousand and $77 thousand for the six months ended June 30, 2014 and 2013, respectively. The total non-cash, share-based compensation expense included in the unaudited condensed consolidated statements of operations for the periods presented is included in the following expense categories:

	Three Months Ended June 30,				Six Months Ended June 30,
(in thousands)	2014		2013		2014		2013
Cost of contract research, services	$	—	$	5	$	—	$	10
Cost of goods sold	—		4		—		7
Administrative and selling	23		32		31		60
Total share-based compensation	$	23	$	41	$	31	$	77

No share-based compensation expense was capitalized during the six months ended June 30, 2014 and 2013. Compensation expense related to stock options to be charged in future periods amounts to approximately $3 thousand at June 30, 2014 and will be recognized over a weighted-average period of 0.10 years as follows:

For the years ended December 31,	Expected Compensation Expense
	(in thousands)
2014	$	3
	$	3

The Company estimates forfeitures at the time of grant and revises, if necessary, in subsequent periods if actual forfeitures differ from those estimates in order to derive the Company’s best estimate of awards ultimately expected to vest.  Forfeitures represent only the unvested portion of a surrendered option and are typically estimated based on historical experience.

At June 30, 2014, the Company had outstanding options under two option plans: the 1996 Equity Incentive Plan (the “1996 Plan”) and the 2007 Stock Equity Plan (the “2007 Plan”, together with the 1996 Plan, the “Plans”).  Both Plans were approved by stockholders and provided that the Board of Directors may grant options to purchase the Company’s common stock to key employees and directors of the Company.  Incentive and non-qualified options must be granted at least at the fair market value of the common stock or, in the case of certain optionees, at 110% of such fair market value at the time of grant. The options may be exercised, subject to certain vesting requirements, for periods up to ten years from the date of issue.  The 1996 Plan expired with respect to the issuance of new grants as of December 10, 2006.  Accordingly, future grants may be made only under the 2007 Plan.

A summary of options outstanding under the Plans as of June 30, 2014 and changes during the six-month period ended June 30, 2014 is as follows:

	Number of Shares		Weighted-Average Exercise Price		Average Remaining Contractual Life (Years)	Aggregate Intrinsic Value (in thousands)
Options Outstanding at December 31, 2013	527,246		$	5.88
Granted	24,000		$	0.85
Exercised	—		$	—
Cancelled/expired	(8,124	)	$	6.24
Options outstanding at June 30, 2014	543,122		$	5.65	4.95	$	7
Options vested and exercisable at June 30, 2014	530,622		$	5.69	4.92	$	7
Option vested and expected to vest at June 30, 2014	542,678		$	5.68	4.93	$	13
Options available for future grant at June 30, 2014	459,759

The aggregate intrinsic value in the table above represents the total intrinsic value, based on the Company’s closing stock price of $0.65 as of June 30, 2014, which would have been received by the option holders had all option holders exercised their options as of that date. The total intrinsic value of options exercised was approximately zero and zero for the six months ended June 30, 2014 and 2013, respectively. The total intrinsic value of options expected to vest at June 30, 2014 was approximately zero, and the weighted average remaining contractual life of outstanding options that are expected to vest is 5.1 years.

The per-share weighted-average fair value of stock options granted during the three and six months ended June 30, 2014 was $0.68 and $0.85, respectively, and $0.58 and $0.58 for the three and six months ended June 30, 2013, respectively, on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions:

Period	Expected Dividend Yield	Risk-Free Interest Rate	Expected Option Life	Expected Volatility Factor
Three Months Ended June 30, 2014	—	1.70%	5.1 years	120.2%
Six Months Ended June 30, 2014	—	1.61%	5.1 years	104.6%
Three Months Ended June 30, 2013	—	0.77%	5.1 years	99.7%
Six Months Ended June 30, 2013	—	0.77%	5.1 years	99.7%

The risk free interest rate reflects treasury yields rates over a term that approximates the expected option life. The expected option life is calculated based on historical lives of all options issued under the Plans.  The expected volatility factor is determined by measuring the actual stock price volatility over a term equal to the expected useful life of the options granted.

Segment Reporting Disclosure

Operating Segments and Related Information

The Company's operations are focused on two primary business areas:  Spire Solar (comprised of solar equipment and solar research) and Spire Biomedical (comprised of biomedical surface treatments and biophotonics research).  Spire Solar and Spire Biomedical operate out of the Company's facility in Bedford, Massachusetts. Each business area is independently managed and has separate financial results that are reviewed by the Board of Directors and Chief Executive Officer and the chief executive officers of each operating division.

On September 18, 2013, the Company completed the sale of the Bio Business Unit to N2 Bio, whereas the Company has a controlling financial interest in N2 Bio and is less than wholly-owned by the Company. N2 Bio qualifies as a variable interest entity and the Company is determined to be the primary beneficiary; therefore assets, liabilities and results of operations of N2 Bio are consolidated into the Company's financial statements. The Bio Business Unit is being reported in our biomedical segment. See Note 13 to the unaudited condensed consolidated financial statements.

The following table presents certain operating division information in accordance with the provisions of ASC 280, Segments Reporting.

Income (loss) from operations is net sales and revenues less cost of sales, selling, general and administrative expenses and internal research and development, but is not affected by non-operating income (expense) or by income taxes. In calculating income (loss) from operations for individual business units, substantial administrative expenses incurred at the operating level that are common to more than one segment are allocated on a net sales basis. Certain corporate expenses of an operational nature are also allocated to the divisions based on factors including occupancy, employment, and purchasing volume. All intercompany transactions have been eliminated.

Variable Interest Entity (Notes)

Variable Interest Entity [Abstract]

Consolidation, Variable Interest Entity, Policy

Variable Interest Entity

The Company has interests in N2 Bio which is a variable interest entity (“VIE”). A VIE is an entity that lacks one or more of the following characteristics (i) the total equity investment at risk is sufficient to enable the entity to finance its activities independently and (ii) the equity holders have the power to direct the activities of the entity that most significantly impact its economic performance, the obligation to absorb the losses of the entity and the right to receive the residual returns of the entity. If the Company is the primary beneficiary of a VIE, the Company is required to consolidate it. To determine if the Company is the primary beneficiary, the Company evaluates whether the Company has the power to direct the activities that most significantly impact the VIE's economic performance and the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. The Company's evaluation includes identification of significant activities and an assessment of the Company's ability to direct those activities based on governance provisions and arrangements to provide or receive product and process technology, product supply, operations services, equity funding, financing and other applicable agreements and circumstances. The Company's assessments of whether the Company is the primary beneficiary of its VIE require significant assumptions and judgments and are reviewed on an ongoing basis based on current facts and circumstances.

On September 18, 2013, the Company, Spire Biomedical, Inc. (the “Subsidiary” and together with the Company, “Spire Bio”) entered into an Asset Purchase Agreement (the “Purchase Agreement”) with N2 Bio pursuant to which N2 Bio agreed to (i) acquire substantially all of the assets of Spire Bio's biomedical business (the “Bio Business Unit”) and (ii) assume and pay certain liabilities related to the purchased assets as set forth in the Purchase Agreement (collectively, the “Transaction”). The Transaction closed on September 18, 2013. The purchase price for the Bio Business Unit was $10.5 million plus the assumption of liabilities of approximately $100 thousand, with $6.0 million paid in cash at closing, a $2.4 million subordinated convertible promissory note, and 310,549 Series A Convertible Preferred Units of N2 Bio valued at approximately $2.1 million ($6.72 per share). The assets and liabilities of the Subsidiary's biomedical business are under common control and were recorded at carryover basis for financial reporting. The difference between the consideration paid and the carrying value of the assets and liabilities acquired by N2 Bio was recorded as a deemed dividend to the Company in the amount of $9.5 million and has been eliminated in consolidation. Mark C. Little was the Chief Executive Officer of the Subsidiary, is a director of the Company and is the Chief Executive Officer of N2 Bio. Mark C. Little is the son of Roger G. Little, Chairman of the Board of Directors of the Company. Roger G. Little is also a member of the Board of Directors of N2 Bio.

On September 18, 2013, N2 Bio entered into a Lease Agreement (the “N2 Bio Bedford Lease”) with SPI-Trust with respect to 27 thousand square feet of space which represents approximately 19% of space in the Bedford, Massachusetts premises. The term of the N2 Bio Bedford Lease commenced on September 18, 2013 and is set to expire on November 30, 2020. The annual rental rate prorated for September 18, 2013 to November 30, 2013 is $16.00 per square foot on a triple net basis, whereby the tenant is responsible for operating expenses, taxes and maintenance of the building. The annual rental rate increases on December 1, 2013 and each anniversary thereafter by $0.50 per square foot.

On September 18, 2013, the Company and N2 Bio entered into a Shared Services Agreement whereby the Company will provide N2 Bio certain services (the “Shared Services”) for a period of three years. It is the intent of the parties that the aggregate fees for the Shared Services shall equal approximately $500 thousand during the first year. Following the first anniversary, N2 Bio may terminate any specific Shared Service with 20 days' written notice to the Company.

The Company has determined that N2 Bio is a VIE because the equity investment at risk from the majority shareholders of N2 Bio is not sufficient to permit N2 Bio to finance its activities without additional subordinated financial support. As discussed above, N2 Bio is subject to a subordinated convertible promissory note due to the Company. The assets of N2 Bio can only be used to settle the obligations of N2 Bio and there is no recourse to the Company related to the third party obligations of or third party arrangements entered into by N2 Bio. Additionally, Mark Little is the Chief Executive Officer of N2 Bio and also a member the Company's Board of Directors. The Company has also determined that the Company has the obligation to absorb losses and the right to receive benefits from N2 Bio that could potentially be significant to it. Therefore, the Company has determined that N2 Bio is a VIE and that the Company is a primary beneficiary of the VIE and must consolidate the financial condition, results of operations and cash flows of N2 Bio with those of its own.

The assets and liabilities from the VIE included in the condensed consolidated balance sheets as of June 30, 2014 and December 31, 2013 are as follows:

Fair Value Measurements

Fair Value Measurements [Abstract]

Fair Value Disclosures

Fair Value Measurements

The hierarchy established under ASC 820-10, Fair Value Measures and Disclosures ("ASC 820-10") gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). As required by ASC 820-10, the Company's available-for-sale investments are classified within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement. The three levels of the fair value hierarchy under ASC 820-10, and its applicability to the Company's available-for-sale investments, are described below:

Level 1 - Pricing inputs are quoted prices available in active markets for identical investments as of the reporting date. As required by ASC 820-10, the Company does not adjust the quoted price for these investments, even in situations where the Company holds a large position and a sale could reasonably impact the quoted price.

Level 2 - Pricing inputs are quoted prices for similar investments, or inputs that are observable, either directly or indirectly, for substantially the full term through corroboration with observable market data. Level 2 includes investments valued at quoted prices adjusted for legal or contractual restrictions specific to these investments.

Level 3 - Pricing inputs are unobservable for the investment, that is, inputs that reflect the reporting entity's own assumptions about the assumptions market participants would use in pricing the asset or liability. Level 3 includes investments that are supported by little or no market activity.    

Valuation Techniques

Fair value is a market-based measure considered from the perspective of a market participant who would buy the asset or assume the liability rather than the Company's own specific measure. All of the Company's fixed income securities are priced using a variety of daily data sources, largely readily-available market data and broker quotes. To validate these prices, the Company compares the fair market values of the Company's fixed income investments using market data from observable and corroborated sources. The Company also performs the fair value calculations for its common stock and mutual fund securities using market data from observable and corroborated sources. In periods of market inactivity, the observability of prices and inputs may be reduced for certain instruments. This condition could cause an instrument to be reclassified from Level 1 to Level 2 or from Level 2 to Level 3. During the six months ended June 30, 2014, none of the Company's instruments were reclassified between Level 1, Level 2, Level 3 and there have been no changes in valuation techniques. Also, as of June 30, 2014, all investments have been sold and the remaining fair value is zero.

The following table presents the financial instruments related to the Company’s available-for-sale investment carried at fair value on a recurring basis as of December 31, 2013 by ASC 820-10 valuation hierarchy (as defined above).

⁽¹⁾  Changes in the fair value of available-for-sale investments are recorded in accumulated other comprehensive income, a component of stockholders’ equity, in the Company’s unaudited condensed consolidated balance sheets.

The carrying amounts reflected in the Company's unaudited condensed consolidated balance sheets for cash, accounts receivable - trade, prepaid expenses and other current assets, accounts payable, accrued liabilities, and capital lease obligations approximate fair value due to their short-term nature and the Company valuation techniques use Level 3 inputs. The fair value of the Company's term loan and revolving lines of credit have been estimated by management based on the terms that it believes it could obtain in the current market for debt of the same terms and similar remaining maturities. Due to the short-term nature of the remaining maturities, recent issuances, frequency of amendments to its terms and the variable interest rates, the carrying value of the term loan and revolving lines of credit approximate fair value at June 30, 2014 and December 31, 2013 and the Company's valuation techniques use Level 3 inputs.

Intangible and Other Assets

Intangible and Other Assets

Patents amounted to $70 thousand and $62 thousand, net of accumulated amortization of $895 thousand and $871 thousand, at June 30, 2014 and December 31, 2013, respectively. Licenses amounted to $71 thousand and $110 thousand, net of accumulated amortization of $77 thousand and $38 thousand, at June 30, 2014 and December 31, 2013, respectively. Patent cost is primarily composed of costs associated with securing and registering patents that the Company has been awarded or that have been submitted to the U.S. Patent and Trademark Office, and the Company believes will be approved. License cost is composed of the cost to acquire rights to the underlying technology or know-how. These costs are capitalized and amortized over their useful lives or terms, using the straight-line method. There are no expected residual values related to these patents.

Amortization expense, relating to patents and licenses, was approximately $31 thousand and $14 thousand for the three months ended June 30, 2014 and 2013, respectively. Amortization expense, relating to patents and licenses, was approximately $63 thousand and $27 thousand for the six months ended June 30, 2014 and 2013, respectively.

For disclosure purposes, the table below includes future amortization expense for patents and licenses owned by the Company as well as estimated amortization expense related to patents that remain pending at June 30, 2014 of $109 thousand. This estimated expense for patents pending assumes that the patents are issued immediately, and therefore are being amortized over five years on a straight-line basis. Estimated amortization expense for the periods ending December 31, is as follows: 

(in thousands)	Amortization Expense

Notes Payable and Credit Arrangements

Prior to their expiration on April 30, 2014, the Company had two separate credit facilities with Silicon Valley Bank (the “Bank” or “SVB”): (i) a Second Amended and Restated Loan and Security Agreement (as amended, the "Revolving Credit Facility") and (ii) an Amended and Restated Export-Import Bank Loan and Security Agreement (as amended, the "Ex-Im Facility") pursuant to which outstanding amounts under this facility were guaranteed by the Export-Import Bank of the United States (the “EXIM Bank”). The credit facilities provided an aggregate amount of $1.5 million under both facilities, with up to $1.0 million under the Revolving Credit Facility and up to $1.5 million under the Ex-Im Facility. Under the credit facilities, interest on outstanding borrowings accrued at a rate per annum equal to the greater of (i) the prime rate plus 2.5% or (ii) 7.0%. The entire amount owed under the credit facilities was repaid by April 30, 2014.

N2 Bio has two separate agreements under one credit facility with Middlesex Savings Bank (“MSB”): (i) a Secured Term Loan and (ii) a Secured Revolving Demand Note. Under the Secured Term Loan, N2 Bio borrowed $6.0 million on September 18, 2013 to finance the purchase of the Bio Business Unit from the Company. The advance made under the Secured Term Loan will bear interest at a fixed rate of 4.5% per annum in eighty-four (84) consecutive monthly payments starting on October 18, 2013. If not sooner paid, the Secured Term Loan shall be due and payable in full on September 18, 2020. The Secured Revolving Demand Note provides an amount available of up to $1.0 million. Advances made under the Secured Revolving Demand Note will bear interest at MSB's prime rate, as determined, plus 0.5% per annum but in no event shall the interest rate be less than 3.75% per annum. The maturity date of the Secured Revolving Demand Note is May 31, 2015.

N2 Bio's obligations under the credit facility are secured by substantially all of the assets of N2 Bio. Advances under the Secured Revolving Demand Note are limited to 75% of eligible receivables. In addition, until all amounts under the credit facility with MSB are repaid, covenants under the credit facility impose restrictions on the N2 Bio's ability to, among other things, incur additional indebtedness, create or permit liens on the N2 Bio's assets, merge, consolidate or dispose of assets (other than in the ordinary course of business), make dividend and other restricted payments, make certain debt or equity investments, make certain acquisitions, engage in certain transactions with affiliates or change the business conducted by the N2 Bio. Any failure by N2 Bio to comply with the covenants and obligations under the credit facility could result in an event of default, in which case MSB may be entitled to declare all amounts owed to be due and payable immediately.

Advances outstanding under the Revolving Credit Facility were zero and $107 thousand at June 30, 2014 and December 31, 2013, respectively.  Advances outstanding under the Ex-Im Facility were zero and $38 thousand at June 30, 2014 and December 31, 2013, respectively.  Advances outstanding under the N2 Bio Secured Term Loan were $5.4 million and $5.8 million at June 30, 2014 and December 31, 2013, respectively. Advances outstanding under the N2 Bio Secured Revolving Demand Note were $1 thousand and $438 thousand at June 30, 2014 and December 31, 2013, respectively. The interest rate per annum on the N2 Bio Secured Term Loan and Secured Revolving Demand Note on June 30, 2014 was 4.5% and 3.75%, respectively. Availability under the Secured Revolving Demand Note was $537 thousand as of June 30, 2014.

The Company has outstanding letters of credit to secure performance obligations and purchase commitments. Holders of the letters of credit are allowed to draw funds up to the face amount of the letter of credit if the Company does not perform as contractually required.  The outstanding letters of credit are secured by restricted cash. Outstanding letters of credit totaled $666 thousand and $170 thousand at June 30, 2014 and December 31, 2013, respectively.

Share-based Compensation Arrangement by Share-based Payment Award [Line Items]

Schedule of Share-based Payment Award, Stock Options, Valuation Assumptions [Table Text Block]

The per-share weighted-average fair value of stock options granted during the three and six months ended June 30, 2014 was $0.68 and $0.85, respectively, and $0.58 and $0.58 for the three and six months ended June 30, 2013, respectively, on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions:

Period	Expected Dividend Yield	Risk-Free Interest Rate	Expected Option Life	Expected Volatility Factor
Three Months Ended June 30, 2014	—	1.70%	5.1 years	120.2%
Six Months Ended June 30, 2014	—	1.61%	5.1 years	104.6%
Three Months Ended June 30, 2013	—	0.77%	5.1 years	99.7%
Six Months Ended June 30, 2013	—	0.77%	5.1 years	99.7%

The risk free interest rate reflects treasury yields rates over a term that approximates the expected option life. The expected option life is calculated based on historical lives of all options issued under the Plans.  The expected volatility factor is determined by measuring the actual stock price volatility over a term equal to the expected useful life of the options granted.
