NOTE 2. - STOCK-BASED COMPENSATION

Stock Options

During the six months ended June 30, 2013, the Company issued 11,000 stock options that vest over a four year period and expire ten years from date of grant. The weighted average exercise price of these stock options is $2.47. During the six months ended June 30, 2012, the Company issued 136,000 stock options that vest over a one to four year period and expire ten years from the date of grant. The weighted average exercise price of these stock options is $5.27. Compensation expense related to stock options without performance-based vesting conditions was $85,000 and $104,000 for the three months ended June 30, 2013 and 2012, respectively. Compensation expense related to stock options without performance-based vesting conditions was $203,000 and $177,000 for the six months ended June 30, 2013 and 2012, respectively.

During the six months ended June 30, 2013, the Company issued no stock options with performance-based vesting conditions.

The weighted average exercise price of these stock options is $4.76. All stock options with performance-based conditions expire ten years from date of grant. Of the unvested stock options outstanding at June 30, 2013, 863,050 are subject to the achievement of certain performance conditions. The performance conditions related to approximately 42,000 of these stock options were deemed probable as of June 30, 2013. Compensation expense related to performance-based stock options, for which vesting was deemed probable, was approximately $56,000 and $40,000 for the three months ended June 30, 2013 and 2012, respectively. Compensation expense related to performance-based stock options, for which vesting was deemed probable, was approximately $112,000 and $85,000 for the six months ended June 30, 2013 and 2012, respectively. The performance conditions related to the remaining options were not deemed probable at June 30, 2013; therefore no compensation expense related to these options has been recorded.

Restricted Stock

The Interphase Corporation 2004 Long-Term Stock Incentive Plan provides for grants of bonus stock awards (“restricted stock”) to its directors and certain employees at no cost to the recipient. Holders of restricted stock are entitled to cash dividends, if declared, and to vote their respective shares. Restrictions limit the sale or transfer of these shares during a predefined vesting period, currently ranging from three to four years, and in some cases vesting is subject to the achievement of certain performance conditions. There were no shares of restricted stock issued during the six months ended June 30, 2013. During the six months ended June 30, 2012, the Company issued 9,000 shares of restricted stock. Upon issuance of restricted stock under the plan, unearned compensation equivalent to the market value at the date of grant is recorded as a reduction to shareholders’ equity and subsequently amortized to expense over the respective restriction periods. Compensation expense related to restricted stock was $25,000 and $36,000 for the three months ended June 30, 2013 and 2012, respectively. Compensation expense related to restricted stock was $56,000 and $69,000 for the six months ended June 30, 2013 and 2012, respectively. As of June 30, 2013, there was $171,000 of total unamortized compensation cost related to unvested restricted stock remaining to be recognized. The expense is expected to be recognized over a weighted-average period of 1.7 years. As of December 31, 2012, there was $261,000 of total unamortized compensation cost related to unvested restricted stock which was expected to be recognized over a weighted-average period of 2.1 years. The following table summarizes the restricted stock activity for the six months ended June 30, 2013:

	Restricted Stock Shares			Weighted Average Grant Date Value
Nonvested restricted stock at December 31, 2012		112,015		$	3.17
Granted		-			-
Vested		(40,195	)		3.08
Cancelled/Forfeited		(10,164	)		3.35
Nonvested restricted stock at June 30, 2013		61,656		$	3.21

NOTE 3. - MARKETABLE SECURITIES

Accounting Standards Codification (“ASC”) Topic 820, Fair Value Measurements and Disclosures, defines fair value, establishes a framework for measuring fair value in accordance with accounting principles generally accepted in the United States, and expands disclosures about fair value measurements. The Company follows ASC 820 in its valuation of its marketable securities. ASC 820 defines fair value as the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 classifies the levels used to measure fair value into the following hierarchy:

Level 1 – Valuations based on quoted prices in active markets for identical assets and liabilities that the reporting entity has the ability to obtain at the measurement date. This level provides the most reliable evidence of fair value.

Level 2 – Valuations based on one or more quoted prices in markets that are not active; quoted prices for similar assets or liabilities in active markets; inputs that are observable other than quoted prices for the asset or the liability; or inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 3 – Valuations based on inputs that are unobservable and significant to the overall fair value measurement.

The Company’s investments in marketable securities primarily consist of investments in debt securities, which are classified as available for sale and presented as current assets on the accompanying condensed consolidated balance sheets. Earnings from debt securities are calculated on a yield to maturity basis and recorded in the results of operations. Unrealized gains or losses for the periods presented were included in other comprehensive (loss) income. Realized gains and losses are computed based on the specific identification method and were not material for the periods presented. Marketable securities are used to secure the Company’s credit facility. The fair values of marketable securities were estimated using the market approach using prices and other relevant information generated by market transactions involving identical or comparable assets. The Company uses quoted market prices in active markets or quoted market prices in markets that are not active to measure fair value. When developing fair value estimates, the Company maximizes the use of observable inputs and minimizes the use of unobservable inputs.

NOTE 4. - INVENTORIES

Inventories are valued at the lower of cost or market and include material, labor and manufacturing overhead. Cost, determined on a first-in, first-out basis, is as follows (in thousands):

	June 30, 2013		December 31, 2012
Raw Materials	$	1,798	$	1,616
Work-in-Process		569		462
Finished Goods		62		141
Total	$	2,429	$	2,219

Valuing inventory at the lower of cost or market involves an inherent level of risk and uncertainty due to technology trends in the industry and customer demand for the Company’s products. Future events may cause significant fluctuations in the Company’s operating results. Inventories are written down when needed to ensure the Company carries inventory at the lower of cost or market. The Company increased reserve requirements by $64,000 and decreased reserve requirements by $5,000 during the three months ended June 30, 2013 and 2012, respectively. The Company increased reserve requirements by $80,000 and $20,000 during the six months ended June 30, 2013 and 2012, respectively.

NOTE 5. - INCOME TAXES

The Company records a valuation allowance when it is “more likely than not” that all or a portion of a deferred tax asset will not be realized. Management reviews all available positive and negative evidence, including the Company’s current and past performance, the market environment in which the Company operates, the utilization of past tax credits, length of carry back and carry forward periods, existing contracts or sales backlog that will result in future profits, as well as other factors. The Company continues to maintain a valuation allowance on all of the net deferred tax assets for the periods presented. Until an appropriate level of profitability is sustained, the Company expects to continue to record a full valuation allowance on future tax benefits except for those that may be generated in foreign jurisdictions. The effective income tax rates for the periods presented differ from the U.S. statutory rate as the Company continues to provide a full valuation allowance for the net deferred tax assets at June 30, 2013 and 2012.

NOTE 6. - RESTRUCTURING CHARGE

On October 19, 2012, the Company committed to a plan intended to improve the balance between the Company’s telecommunications product expenses with the reduced revenue levels of this product line. Under the 2012 restructuring plan, the Company reduced its workforce by 10 regular full-time positions. As a result of the 2012 restructuring plan, the Company recorded a restructuring charge of $253,000, classified as an operating expense, in the fourth quarter of 2012 related to future cash expenditures to cover employee severance and benefits. During the three months ended March 31, 2013, the Company reduced its restructuring charge by $67,000 related to reduced future cash expenditures related to severance and benefits for a former employee. The former employee’s accepting other employment in April 2013 reduced the amount of severance and benefit payouts by the Company. The following table summarizes the timing of payments under the restructuring plan (in thousands):

Description	Severance & Fringe Benefits
Restructuring charge	$	253
Cash payments during quarter ended December 31, 2012		(91	)

NOTE 7. - CREDIT FACILITY

The Company maintains a $5.0 million revolving bank credit facility maturing December 19, 2015. The applicable interest rate on outstanding balances is LIBOR plus 1.0% to 1.5% based on certain factors included in the credit agreement. At June 30, 2013 and December 31, 2012, the Company’s interest rate on the $3.5 million outstanding balance was 1.7% and 1.2%, respectively. The unused portion of the credit facility is subject to an unused facility fee ranging from .25% to .75% depending on total deposits with the creditor. All borrowings under this facility are secured by marketable securities. The outstanding balance of $3.5 million as of June 30, 2013 and December 31, 2012 is classified as long-term debt on the Company’s condensed consolidated balance sheets. Subsequent to June 30, 2013 and prior to the Company’s filing of the condensed consolidated financial statements, the outstanding balance on the credit facility was repaid.

NOTE 8. - EARNINGS PER SHARE

NOTE 9. - SHAREHOLDERS’ EQUITY

The Board of Directors adopted a Shareholder Rights Plan (the “Plan”) and, under the Plan, declared a non-taxable dividend, paid at the close of business on August 9, 2011 (the “Record Date”), of one common share purchase right (a “Right”) for each outstanding share of Common Stock. From the Record Date until the Rights become exercisable, the Rights will be attached to all outstanding shares of Common Stock and, therefore, will be represented by the certificates evidencing the shares of Common Stock and transferrable only with the shares of Common Stock. A Right will be exercisable, upon certain conditions, to purchase one share of Common Stock from the Company at a price of $39, subject to adjustment. The Rights will become exercisable, and separate from the shares of Common Stock, upon the earlier of:

(1) ten business days following the date of the first public announcement (the “Stock Acquisition Date”) that a person or a group of affiliated or associated persons has acquired, or obtained the right to acquire, beneficial ownership of 15% or more of the outstanding shares of Common Stock (an “Acquiring Person”), or

(2) ten business days (or such later date as the Board of Directors may determine) following the commencement of a tender or exchange offer that, if consummated, would result in a person or group of persons becoming an Acquiring Person.

Upon a Stock Acquisition Date, each holder of a Right (other than an Acquiring Person) will be entitled to receive, upon exercise of the Right, shares of Common Stock at a 50% discount. Also, if, at any time following a Stock Acquisition Date, the Company is acquired in a merger or business combination and its Common Stock is exchanged or converted, or if 50% or more of the Company’s assets, cash flow or earning power is sold or transferred, then each holder of a Right (other than an Acquiring Person) will be entitled to receive, upon exercise of the Right, shares of the acquirer’s common stock at a 50% discount. Further, at any time after a person or group of persons becomes an Acquiring Person, but before any person or group of persons becomes the beneficial owner of 50% or more of the outstanding shares of Common Stock, the Company may cause each exercisable Right to be exchanged for one share of Common Stock. The Rights will expire at the close of business on July 29, 2021, or such other date as the Board of Directors may determine under certain circumstances. The Board of Directors may terminate the Plan or cause the Company to redeem the Rights, at a price of $0.001 per Right, at any time before the earlier of a Stock Acquisition Date or the expiration of the Rights. The Company has reserved 90,315,210 shares of Common Stock for possible issuance upon exercise of Rights under the Plan.

Item 2.          MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Management’s Discussion and Analysis of Financial Condition and Results of Operations in this Form 10-Q should be read in conjunction with Management’s Discussion and Analysis of Financial Condition and Results of Operations and other material included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

FORWARD-LOOKING STATEMENTS

This report contains forward-looking statements about the business, financial condition and prospects of the Company. These statements are made under the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. The actual results of the Company could differ materially from those indicated by the forward-looking statements because of various risks and uncertainties, including (without limitation) effects of the ongoing issues in global credit and financial markets, our reliance on a limited number of customers, the lack of spending improvements in the telecommunications and computer networking industries, significant changes in product demand, the development and introduction of new products and services, changes in competition, various inventory risks due to changes in market conditions and other risks and uncertainties indicated in Item 1A of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 and in the Company’s other filings and reports with the Securities and Exchange Commission. All of the foregoing risks and uncertainties are beyond the ability of the Company to control, and in many cases, the Company cannot predict the risks and uncertainties that could cause its actual results to differ materially from those indicated by the forward-looking statements. When used in this report, the words “believes”, “plans”, “expects”, “will”, “intends,” and “anticipates” and similar expressions as they relate to the Company or its management are intended to identify forward-looking statements.

RESULTS OF OPERATIONS

Revenue

Total revenue increased 10% to $3.8 million for the three months ended June 30, 2013, compared to $3.5 million for the same period in the prior year. Our telecommunications and enterprise product revenue increased slightly to $2.8 million for the three months ended June 30, 2013, compared to $2.7 million in the comparable period in the prior year. Our services revenues increased 42% to $1 million for the three months ended June 30, 2013, compared to $708,000 for the same period in the previous year. This increase was primarily related to a large order from an electronic contract manufacturing customer. We expect to continue to fulfill large orders from this customer going forward. All other revenues increased to $41,000, compared to $28,000 in the comparable period last year.

Total revenue decreased 5% to $7.1 million for the six months ended June 30, 2013, compared to $7.5 million for the same period in the prior year. Our telecommunications and enterprise product revenue decreased 11% to $5.3 million for the six months ended June 30, 2013, compared to $5.9 million in the comparable period in the prior year. This decrease was primarily driven by two telecommunications products that are end-of-life, which led to significantly reduced revenue from these products in the first half of 2013. Our services revenues increased 16% to $1.7 million for the six months ended June 30, 2013, compared to $1.5 million for the same period in the previous year. This increase was primarily related to a large order from an electronic contract manufacturing customer. We expect to continue to fulfill large orders from this customer going forward. All other revenues increased to $55,000, compared to $51,000 in the comparable period last year.

During the second quarter of 2013, sales to three customers individually accounted for approximately 30%, 19% and 10% of total revenues, respectively. During the second quarter of 2012, sales to three customers individually accounted for approximately 29%, 17% and 12% of total revenues, respectively. No other customers individually accounted for more than 10% of our consolidated revenues in the periods presented.

Included in accounts receivable at June 30, 2013 was $1.1 million and $814,000 due individually from two customers, respectively. Included in accounts receivable at December 31, 2012 was $721,000, $401,000, $387,000 and $312,000, due individually from four customers, respectively. No other customers individually accounted for more than 10% of our accounts receivable in the periods presented.

13

Gross Margin

Gross margin as a percentage of revenue was 37% and 45% for the three months ended June 30, 2013 and 2012, respectively. The decrease in gross margin percentage in the second quarter of 2013 compared to the same period in the prior year was primarily due to a revenue mix shift toward lower margin products and services and an increase of $69,000 in excess and obsolete inventory charges, partially offset by increased utilization of our manufacturing facility.

Gross margin as a percentage of revenue was 38% and 46% for the six months ended June 30, 2013 and 2012, respectively. The decrease in gross margin percentage was primarily due to a revenue mix shift toward lower margin products and services and an increase of $60,000 in excess and obsolete inventory charges, partially offset by increased utilization of our manufacturing facility.

We believe that pricing pressures in the industry and our anticipated future product mix may further reduce our gross margin percentage in future periods.

Research and Development

Our investment in research and development was $857,000 and $854,000 for the three months ended June 30, 2013 and 2012, respectively. During the three months ended June 30, 2013, there was a decrease in professional services activities, which resulted in a decrease in services revenues. Engineering costs associated with these professional services activities generate revenue; therefore, the related expenses are recorded as cost of sales rather than research and development operating expenses. The decrease in professional services activities resulted in an increase in research and development expenses during the period of approximately $275,000. This increase in research and development expense was offset by several items. A decrease in personnel-related expenses, as a result of the 2012 restructuring plan, represents approximately 44% of the offsetting items and a decrease in other personnel-related expenses, not associated with the 2012 restructuring plan, represents approximately 33% of the offsetting items. The remaining offsetting items are made up of variable project related expenses. See Note 6 in the notes to condensed consolidated financial statements for more information on the restructuring plan. As a percentage of revenue, research and development expenses were approximately 22% in the second quarter of 2013 compared to approximately 25% for the same period in the prior year. The decrease in research and development expenses as a percentage of total revenue was due to revenue increasing at a higher rate than research and development expenses.

Our investment in research and development was $1.7 million and $1.8 million for the six months ended June 30, 2013 and 2012, respectively. This decrease in research and development expense was made up of several items. A decrease in personnel-related expenses, as a result of the 2012 restructuring plan, represents approximately 35% of the decrease and a decrease in other personnel-related expenses, not associated with the 2012 restructuring plan, represents approximately 29% of the decrease. The remaining decrease was made up of variable project related expenses. These decreases in research and development expense were partially offset by a decrease in professional services activities. Engineering costs associated with these professional services activities generate revenue; therefore, the related expenses are recorded as cost of sales rather than research and development operating expenses. The decrease in professional services activities resulted in an increase in research and development expenses during the period of approximately $545,000. See Note 6 in the notes to condensed consolidated financial statements for more information on the restructuring plan. As a percentage of revenue, research and development expenses were approximately 24% for the six months ended June 30, 2013 and 2012. We will continue to monitor the level of our investments in research and development concurrently with actual revenue results.

Sales and Marketing

Sales and marketing expenses were $732,000 and $1.1 million for the three months ended June 30, 2013 and 2012, respectively. Approximately 48% of the decrease in sales and marketing expense was due to a decrease in personnel-related expenses. The remaining decrease in sales and marketing expense was primarily due to a decrease in marketing and tradeshow related expenses. As a percentage of revenue, sales and marketing expenses were approximately 19% for the second quarter of 2013, compared to approximately 33% for the same period in the prior year. The decrease in sales and marketing expenses as a percentage of total revenue was due to sales and marketing expenses decreasing while revenue increased.

14

Sales and marketing expenses were $1.4 million and $2.0 million for the six months ended June 30, 2013 and 2012, respectively. Approximately 54% of the decrease in sales and marketing expense was due to a decrease in personnel-related expenses. The remaining decrease in sales and marketing expense was primarily due to a decrease in marketing and tradeshow related expenses. As a percentage of revenue, sales and marketing expenses were approximately 20% for the six months ended June 30, 2013, compared to approximately 27% for the same period in the prior year. The decrease in sales and marketing expenses as a percentage of total revenue was due to sales and marketing expenses decreasing at a higher rate than revenue. We will continue to monitor the level of sales and marketing costs concurrently with actual revenue results.

General and Administrative

General and administrative expenses were $691,000 and $731,000 for the three months ended June 30, 2013 and 2012, respectively. As a percentage of revenue, general and administrative expenses were approximately 18% for the second quarter of 2013 and 21% for the same period in the prior year. The decrease in general and administrative expenses as a percentage of total revenue was due to general and administrative expenses decreasing while revenue increased.

General and administrative expenses were $1.6 million and $1.7 million for the six months ended June 30, 2013 and 2012, respectively. The decrease in general and administrative expense was primarily due to a decrease in depreciation and amortization expense. As a percentage of revenue, general and administrative expenses were approximately 22% for the six months ended June 30, 2013 and 2012. We will continue to monitor the level of general and administrative costs concurrently with actual revenue results.

Restructuring Charge

On October 19, 2012, we committed to a plan intended to improve the balance between our telecommunications product expenses with the reduced revenue levels of this product line. Under the 2012 restructuring plan, we reduced our workforce by 10 regular full-time positions. As a result of the 2012 restructuring plan, we recorded a restructuring charge of $253,000, classified as an operating expense, in the fourth quarter of 2012 related to future cash expenditures to cover employee severance and benefits. This plan is expected to result in savings of approximately $1.0 million to $1.6 million in annualized operating costs. During the three months ended March 31, 2013, we reduced our restructuring charge by $67,000 related to reduced future cash expenditures related to severance and benefits for a former employee. The former employee’s accepting other employment in April 2013 reduced the amount of severance and benefit payouts by us. These amounts were paid out under the restructuring plan by June 30, 2013. See Note 6 in the notes to the consolidated financial statements for more information regarding the 2012 restructuring plan.

Other (Loss) Income, Net

Other loss, net was $2,000 for the three months ended June 30, 2013. Other income, net was $9,000 for the three months ended June 30, 2012. Other loss, net was $343,000 for the six months ended June 30, 2013. Other income, net was $13,000 for the six months ended June 30, 2012. The loss for the six months ended June 30, 2013 was primarily related to the decision of the Labor Court of Boulogne-Billancourt, France on March 22, 2013 related to specific French employment indemnity claims of four former employees. The Court ruled in our favor regarding all other claims brought by the twenty-two former employees. See Part II, Item 1. “Legal Proceedings” below for more information.

Income Taxes

Our tax expense rate was 0.9% for the six months ended June 30, 2013, compared to a tax benefit rate of 0.4% for the six months ended June 30, 2012. The effective income tax rates for the periods presented differ from the U.S. statutory rate as we continue to provide a full valuation allowance for our net deferred tax assets at June 30, 2013 and June 30, 2012. The tax expense and benefit in the periods primarily relate to tax in a foreign jurisdiction.

Net Loss

We reported a net loss of $895,000 for the three months ended June 30, 2013 and a net loss of approximately $1.1 million for the three months ended June 30, 2012. Basic loss per share for the three months ended June 30, 2013 was ($0.13). Basic loss per share for the three months ended June 30, 2012 was ($0.16).

15

We reported a net loss of approximately $2.3 million for the six months ended June 30, 2013 and a net loss of approximately $2.1 million for the six months ended June 30, 2012. Basic loss per share for the six months ended June 30, 2013 was ($0.33). Basic loss per share for the six months ended June 30, 2012 was ($0.30).

LIQUIDITY AND CAPITAL RESOURCES

Consolidated Cash Flows

Cash and cash equivalents decreased $673,000 from December 31, 2012 to June 30, 2013 and decreased approximately $2.2 million from December 31, 2011 to June 30, 2012. Cash flows are impacted by operating, investing and financing activities.

Operating Activities

Trends in cash flows from operating activities for the six months ended June 30, 2013 and 2012 are generally similar to the trends in our earnings except for provision for uncollectible accounts and returns, provision for excess and obsolete inventories, depreciation and amortization and stock-based compensation expense. Cash used in operating activities totaled $1.5 million for the six months ended June 30, 2013, compared to a net loss of $2.3 million for that period. Provision for uncollectible accounts and returns increased $11,000 for the six months ended June 30, 2013 compared to the same period in 2012. Provision for excess and obsolete inventories increased $60,000 for the six months ended June 30, 2013 compared to the same period in 2012. Depreciation and amortization decreased $108,000 for the six months ended June 30, 2013 compared to the same period in 2012. Amortization of stock-based compensation increased $40,000 for the six months ended June 30, 2013 compared to the same period in 2012.

Changes in assets and liabilities result primarily from the timing of production, sales, purchases and payments. Changes in assets and liabilities generally tend to even out over time and result in trends in cash flows from operating activities generally reflecting earnings trends.

Investing Activities

Cash provided by investing activities totaled $795,000 and cash used in investing activities totaled $805,000 for the six months ended June 30, 2013 and 2012, respectively. Cash provided by or used in investing activities in each of the periods related principally to our investments in marketable securities and purchases of property and equipment and capitalized software. Additions to property and equipment and capitalized software were $21,000 for the six months ended June 30, 2013, compared to $229,000 for the six months ended June 30, 2012. The additions for the six months ended June 30, 2013 primarily related to equipment purchases for our manufacturing function. The additions for the six months ended June 30, 2012 primarily related to software and equipment purchases for penveu^® and equipment purchases for our manufacturing function. Purchases of marketable securities were $6.9 million and $4.8 million for the six months ended June 30, 2013 and 2012, respectively. Proceeds from the sale of marketable securities increased to $7.7 million for the six months ended June 30, 2013, compared to $4.2 million for the six months ended June 30, 2012.

Financing Activities

There was no net cash provided by or used in financing activities for the six months ended June 30, 2013. Net cash provided by financing activities totaled $821,000 for the six months ended June 30, 2012, consisting solely of proceeds from the exercise of stock options.

16

Restructuring Charge

On October 19, 2012, we committed to a plan intended to improve the balance between our telecommunications product expenses with the reduced revenue levels of this product line. Under the 2012 restructuring plan, we reduced our workforce by 10 regular full-time positions. As a result of the 2012 restructuring plan, we recorded a restructuring charge of $253,000, classified as an operating expense, in the fourth quarter of 2012 related to future cash expenditures to cover employee severance and benefits. During the three months ended March 31, 2013, we reduced our restructuring charge by $67,000 related to reduced future cash expenditures related to severance and benefits for a former employee. The former employee’s accepting other employment in April 2013 reduced the amount of severance and benefit payouts by us. The following table summarizes the timing of payments under the restructuring plan (in thousands):

Description	Severance & Fringe Benefits
Restructuring charge	$	253
Cash payments during quarter ended December 31, 2012		(91	)
Reduction of restructuring charge during quarter ended March 31, 2013		(67	)

Cash payments during quarter ended June 30, 2013		(23	)
Remaining liability as of June 30, 2013	$	-

Commitments

At June 30, 2013, we had no material commitments to purchase capital assets; however, planned capital expenditures for the remainder of 2013 are estimated at approximately $180,000, which primarily relates to manufacturing equipment. At June 30, 2013, we had approximately $270,000 of non-cancelable purchase commitments for inventory as part of the normal course of business. Our significant long-term obligations are future debt payments, operating leases on facilities and our phone system. We have not paid any dividends since our inception and do not anticipate paying any dividends in 2013.

Other

Management believes borrowing availability under the revolving credit facility, together with cash on hand and marketable securities, will be sufficient to meet our liquidity needs for working capital, capital expenditures, debt service and other obligations for the next twelve months. To the extent our actual operating results or other developments differ from our expectations, our liquidity could be adversely affected. Actual results could differ materially from our expectations because of various risks and uncertainties, including (without limitation), our reliance on a limited number of customers, the lack of spending improvements in the telecommunications and computer networking industries, significant changes in product demand, delays in the development and introduction of penveu and other new products and services and other risks and uncertainties disclosed in our Annual Report on Form 10-K for the year ended December 31, 2012.

We periodically evaluate our liquidity requirements, alternative uses of capital, capital needs and available resources in view of, among other things, our capital expenditure requirements and estimated future operating cash flows. As a result of this process, we have in the past and may in the future seek to raise additional capital, refinance or restructure indebtedness, issue additional securities, repurchase shares of our common stock or take a combination of such steps to manage our liquidity and capital resources. In the normal course of business, we may review opportunities for acquisitions, joint ventures or other business combinations. In the event of any such transaction, we may consider using available cash, issuing additional equity securities or increasing the indebtedness of the Company or its subsidiaries.

Critical Accounting Policies

There have been no significant changes to our critical accounting policies from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2012.

Recently Issued Accounting Pronouncements

See Note 11 in the notes to the condensed consolidated financial statements for more information regarding recently issued accounting pronouncements, including the dates of adoption and estimated effects on our condensed consolidated financial statements.

Item 3.      QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Foreign Currency Risk

We are exposed to adverse movements in foreign currency exchange rates because we conduct business on a global basis and, in some cases, in foreign currencies. The Company’s operations in France were transacted in the local currency and converted into U.S. Dollars based on published exchange rates for the periods reported and were therefore subject to risk of exchange rate fluctuations. The Euro to U.S. Dollar translation accounted for charges of $1,000 for the three months ended June 30, 2013 and 2012. The Euro to U.S. Dollar translation accounted for charges of $4,000 and $12,000 for the six months ended June 30, 2013 and 2012, respectively.     

Market Price Risk

We had no equity hedge contracts outstanding as of June 30, 2013 or December 31, 2012.

Interest Rate Risk

Our investments are subject to interest rate risk. Interest rate risk is the risk that our financial condition and results of operations could be adversely affected due to movements in interest rates. We invest our cash in a variety of interest-earning financial instruments, including bank time deposits, money market funds, and variable rate and fixed rate obligations of corporations and national governmental entities and agencies. Due to the demand nature of our money market funds and the short-term nature of our time deposits and debt securities portfolio, these assets are particularly sensitive to changes in interest rates. We manage this risk through investments with shorter-term maturities and varying maturity dates.

A hypothetical 50 basis point increase in interest rates would result in an approximate decrease of less than 1% in the fair value of our available-for-sale securities at June 30, 2013. This potential change is based on sensitivity analyses performed on our marketable securities at June 30, 2013. Actual results may differ materially. The same hypothetical 50 basis point increase in interest rates would have resulted in an approximate decrease of less than 1% in the fair value of our available-for-sale securities at December 31, 2012.

We maintain a $5.0 million revolving bank credit facility maturing December 19, 2015 with an applicable interest rate on any outstanding balances under the credit facility based on London Interbank Offered Rate (“LIBOR”) plus 1.0% to 1.5% applicable margin rate based on certain factors included in our credit agreement. The interest rate on the borrowings under the revolving credit facility was 1.7% and 1.2% at June 30, 2013 and December 31, 2012, respectively. The unused portion of the credit facility is subject to an unused facility fee ranging from .25% to .75% depending on total deposits with the creditor. A hypothetical 50 basis point increase in LIBOR would increase annual interest expense on this credit facility by $17,500. All borrowings under this facility are secured by marketable securities. Subsequent to June 30, 2013 and prior to the Company’s filing of the condensed consolidated financial statements, the outstanding balance on the credit facility was repaid.

18

Item 4.          CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

The Company’s management, under the supervision of our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), performed an evaluation of the effectiveness of the design and operation of the Company’s disclosure controls and procedures as of the end of the period covered by this quarterly report using the “Internal Control – Integrated Framework (1992)” created by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) framework. Based on that evaluation, the CEO and CFO concluded that the Company’s disclosure controls and procedures are designed, and are effective, to give reasonable assurance that the information required to be disclosed by the Company in reports that it files under the Securities Exchange Act of 1934 is accumulated and communicated to management, including the CEO and CFO, to allow timely decisions regarding disclosure and that information is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission.

Changes in Internal Controls

The Company maintains a system of internal controls that is designed to provide reasonable assurance that its books and records accurately reflect, in all material respects, the transactions of the Company and that its established policies and procedures are adhered to. From time to time the Company may experience changes to its internal controls due, for example, to employee turnover, re-balancing of workloads, extended absences and promotions of employees. However, there were no changes in our internal controls over financial reporting during the quarter ended June 30, 2013 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

PART II

OTHER INFORMATION

Item 1.          LEGAL PROCEEDINGS

Twenty-five former employees (“Plaintiffs”) of Interphase SAS, a subsidiary of Interphase Corporation, brought suit in France against Interphase SAS alleging various causes of action and rights to damages relating to claims of wrongful dismissal of employment, specific French employment indemnities, general economic losses, and contractual claims relating specifically to their employment relationship and contracts entered into between the individual and Interphase SAS. The lawsuits were filed between November 2010 and April 2011 and were filed before the Labor Court of Boulogne-Billancourt, France and the Administrative Court of Cergy-Pontoise, France. The various claims and assertions arise from, and relate to, the Plaintiffs’ release from employment as part of the restructuring actions taken during the third quarter of 2010. The updated statement of claim is for an aggregate payment of approximately €2.1 million, which translated to approximately $2.7 million at June 30, 2013, related to these claims. The Company believed that the Plaintiffs’ claims were without merit and vigorously defended itself in this lawsuit.

On March 22, 2012, a hearing was conducted before the Labor Court of Boulogne-Billancourt, France related to the claims of twenty-three of the twenty-five former employees. On May 31, 2012, the Court reported that the four judges’ votes were split; therefore, another hearing before the Labor Court took place on January 25, 2013. The same four judges heard the case again, along with a professional judge from another court to ensure that a majority decision will be reached.

The decision of the Labor Court regarding the claims of twenty-two former employees was rendered on March 22, 2013. All employee claims were rejected, because the Labor Court ruled that the redundancy procedure was regular and that redundancies were based on valid reasons, except claims from four plaintiffs based on non-competition indemnity (amounting in total to €265,000, which translated to approximately $340,000 at March 31, 2013). During the three months ended March 31, 2013, the Company recorded a charge of approximately $340,000 classified as other loss on its condensed consolidated statements of operations and as a current liability on its condensed consolidated balance sheets. Related to the claims of four plaintiffs based on non-competition indemnity, one of these plaintiffs has filed an appeal; therefore, related to this plaintiff, the Company is currently evaluating its appeal options. The Company is not filing an appeal related to the other three plaintiffs claims based on non-competition indemnity. Fourteen other former employees filed an appeal. The Company intends to defend itself against these appeals.

On May 22, 2012, a hearing was conducted before the Labor Court of Boulogne-Billancourt, France related to the claims of one of the twenty-five former employees with non-executive status. On July 31, 2012, the Court reported that the four judges’ votes were split; therefore, the Labor Court decided to join this case to the cases of the other twenty-three former employees described above in order to be heard again at the same hearing. Therefore, this case was heard again at the hearing on January 25, 2013 before the Labor Court. On March 22, 2013, the Labor Court rejected this former employee's claims.

Among the twenty-five cases described above, two former employees were made redundant related to a decision of the Labor Inspector to authorize their redundancy. Because of their protected status as employee representatives, their redundancy required the prior authorization of the French administration. Each of those former employees also filed a claim before the Administrative Tribunal in order to challenge the decision of the Labor Inspector which authorized their redundancy. Although each such claim or action is directed against the State, Interphase is also a party to these proceedings. These cases are still pending before the Administrative Tribunal, and the date of the hearing has not been scheduled since additional briefs and evidence are still being communicated.

For one of the twenty-five former employees, who was an employee representative, the Labor Court granted the Company’s motion at the January 25, 2013 hearing; the Labor Court rejected the plaintiff’s claim to hear the case on the merits, regarding the alleged irregularity of the information and consultation procedure, and postponed this case in deference to the pending case before the Administrative Tribunal as described above. This case will be heard again on September 27, 2013. It is likely that the Labor Court will render the same decision and again postpone the hearing until the Administrative Tribunal makes its decision.

On June 12, 2012, a hearing was conducted with the Labor Court of Boulogne-Billancourt, France related to the claims of one of the twenty-five former employees, who was also an employee representative. The Labor Court granted the Company’s motion and rejected the plaintiff’s claim to hear the case on the merits, regarding the alleged irregularity of the information and consultation procedure, and decided to postpone this case in deference to the pending case before the Administrative Tribunal as described above. This case was heard again on May 28, 2013. The Labor Court rendered the same decision and again postponed the hearing until the Administrative Tribunal makes its decision; therefore, this case will be heard again on June 17, 2014.

Item 1A.     RISK FACTORS

There have been no material changes from the risk factors disclosed in our Annual Report on Form 10-K for the year ended December 31, 2012, except as follows:

The common stock is now listed on the Nasdaq Capital Market. If the stock does not continue to be traded on an established exchange, an active trading market may not exist and the trading price of the stock may decline.

On April 11, 2013, the Company received notification from the Listing Qualifications Department of the Nasdaq Stock Market LLC (“Nasdaq”) that the Company’s application to list its common stock on the Nasdaq Capital Market was approved and that the listing of the Company’s securities was transferred from the Nasdaq Global Market to the Nasdaq Capital Market at the opening of business on April 15, 2013. The Nasdaq Capital Market is one of the three markets for Nasdaq-listed securities and generally operates in the same manner as the Nasdaq Global Market. Companies listed on the Nasdaq Capital Market must meet certain financial requirements and adhere to Nasdaq’s corporate governance standards. The Company’s common stock will continue to trade under the symbol “INPH”.

The Company currently anticipates that it will be able to satisfy the continuing listing standards for the Nasdaq Capital Market. Nevertheless, there can be no assurance that it will be able to do so. If there were a failure to satisfy the continued listing requirements and the deficiency could not be corrected or resolved, the Company's common stock could be delisted by the Nasdaq Capital Market. In that event, the common stock may be eligible to be trade on the OTC Bulletin Board or the Pink OTC Markets. In such an event, it may become more difficult to dispose of, or obtain accurate quotations for the price of, our common stock, and there would also likely be a reduction in our coverage by the news media, which could cause the price of the common stock to decline further.

NOTE 11. - RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In February 2013, the FASB issued ASU 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. The amendments require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income. This ASU is effective prospectively for interim and annual periods beginning after December 15, 2012. The Company’s adoption of this update did not have a material impact on the consolidated financial statements.

Inventory Disclosure [Abstract]

Inventory Disclosure [Text Block]

NOTE 4. - INVENTORIES

Inventories are valued at the lower of cost or market and include material, labor and manufacturing overhead. Cost, determined on a first-in, first-out basis, is as follows (in thousands):

	June 30, 2013		December 31, 2012
Raw Materials	$	1,798	$	1,616
Work-in-Process		569		462
Finished Goods		62		141
Total	$	2,429	$	2,219

Valuing inventory at the lower of cost or market involves an inherent level of risk and uncertainty due to technology trends in the industry and customer demand for the Company’s products. Future events may cause significant fluctuations in the Company’s operating results. Inventories are written down when needed to ensure the Company carries inventory at the lower of cost or market. The Company increased reserve requirements by $64,000 and decreased reserve requirements by $5,000 during the three months ended June 30, 2013 and 2012, respectively. The Company increased reserve requirements by $80,000 and $20,000 during the six months ended June 30, 2013 and 2012, respectively.

NOTE 2. - STOCK-BASED COMPENSATION

Stock Options

During the six months ended June 30, 2013, the Company issued 11,000 stock options that vest over a four year period and expire ten years from date of grant. The weighted average exercise price of these stock options is $2.47. During the six months ended June 30, 2012, the Company issued 136,000 stock options that vest over a one to four year period and expire ten years from the date of grant. The weighted average exercise price of these stock options is $5.27. Compensation expense related to stock options without performance-based vesting conditions was $85,000 and $104,000 for the three months ended June 30, 2013 and 2012, respectively. Compensation expense related to stock options without performance-based vesting conditions was $203,000 and $177,000 for the six months ended June 30, 2013 and 2012, respectively.

During the six months ended June 30, 2013, the Company issued no stock options with performance-based vesting conditions. During the six months ended June 30, 2012, the Company issued 448,000 stock options with performance-based vesting conditions for the years ended December 31, 2012, 2013, 2014, and 2015, the achievement of which would result in pro rata vesting per year in February 2013, 2014, 2015, and 2016, respectively. The weighted average exercise price of these stock options is $4.76. All stock options with performance-based conditions expire ten years from date of grant. Of the unvested stock options outstanding at June 30, 2013, 863,050 are subject to the achievement of certain performance conditions. The performance conditions related to approximately 42,000 of these stock options were deemed probable as of June 30, 2013. Compensation expense related to performance-based stock options, for which vesting was deemed probable, was approximately $56,000 and $40,000 for the three months ended June 30, 2013 and 2012, respectively. Compensation expense related to performance-based stock options, for which vesting was deemed probable, was approximately $112,000 and $85,000 for the six months ended June 30, 2013 and 2012, respectively. The performance conditions related to the remaining options were not deemed probable at June 30, 2013; therefore no compensation expense related to these options has been recorded.

The weighted-average remaining contractual life of stock options outstanding and exercisable at June 30, 2013 and 2012 was 5.77 years and 3.28 years, respectively.

The following table summarizes the combined stock option activity under all of the plans:

	Number of Options			Weighted Average Option Price

Restricted Stock

The Interphase Corporation 2004 Long-Term Stock Incentive Plan provides for grants of bonus stock awards (“restricted stock”) to its directors and certain employees at no cost to the recipient. Holders of restricted stock are entitled to cash dividends, if declared, and to vote their respective shares. Restrictions limit the sale or transfer of these shares during a predefined vesting period, currently ranging from three to four years, and in some cases vesting is subject to the achievement of certain performance conditions. There were no shares of restricted stock issued during the six months ended June 30, 2013. During the six months ended June 30, 2012, the Company issued 9,000 shares of restricted stock. Upon issuance of restricted stock under the plan, unearned compensation equivalent to the market value at the date of grant is recorded as a reduction to shareholders’ equity and subsequently amortized to expense over the respective restriction periods. Compensation expense related to restricted stock was $25,000 and $36,000 for the three months ended June 30, 2013 and 2012, respectively. Compensation expense related to restricted stock was $56,000 and $69,000 for the six months ended June 30, 2013 and 2012, respectively. As of June 30, 2013, there was $171,000 of total unamortized compensation cost related to unvested restricted stock remaining to be recognized. The expense is expected to be recognized over a weighted-average period of 1.7 years. As of December 31, 2012, there was $261,000 of total unamortized compensation cost related to unvested restricted stock which was expected to be recognized over a weighted-average period of 2.1 years. The following table summarizes the restricted stock activity for the six months ended June 30, 2013:

	Restricted Stock Shares			Weighted Average Grant Date Value

NOTE 5. - INCOME TAXES

The Company records a valuation allowance when it is “more likely than not” that all or a portion of a deferred tax asset will not be realized. Management reviews all available positive and negative evidence, including the Company’s current and past performance, the market environment in which the Company operates, the utilization of past tax credits, length of carry back and carry forward periods, existing contracts or sales backlog that will result in future profits, as well as other factors. The Company continues to maintain a valuation allowance on all of the net deferred tax assets for the periods presented. Until an appropriate level of profitability is sustained, the Company expects to continue to record a full valuation allowance on future tax benefits except for those that may be generated in foreign jurisdictions. The effective income tax rates for the periods presented differ from the U.S. statutory rate as the Company continues to provide a full valuation allowance for the net deferred tax assets at June 30, 2013 and 2012.

Fair Value Disclosures [Abstract]

Fair Value Disclosures [Text Block]

NOTE 3. - MARKETABLE SECURITIES

Accounting Standards Codification (“ASC”) Topic 820, Fair Value Measurements and Disclosures, defines fair value, establishes a framework for measuring fair value in accordance with accounting principles generally accepted in the United States, and expands disclosures about fair value measurements. The Company follows ASC 820 in its valuation of its marketable securities. ASC 820 defines fair value as the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 classifies the levels used to measure fair value into the following hierarchy:

Level 1 – Valuations based on quoted prices in active markets for identical assets and liabilities that the reporting entity has the ability to obtain at the measurement date. This level provides the most reliable evidence of fair value.

Level 2 – Valuations based on one or more quoted prices in markets that are not active; quoted prices for similar assets or liabilities in active markets; inputs that are observable other than quoted prices for the asset or the liability; or inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 3 – Valuations based on inputs that are unobservable and significant to the overall fair value measurement.

The Company’s investments in marketable securities primarily consist of investments in debt securities, which are classified as available for sale and presented as current assets on the accompanying condensed consolidated balance sheets. Earnings from debt securities are calculated on a yield to maturity basis and recorded in the results of operations. Unrealized gains or losses for the periods presented were included in other comprehensive (loss) income. Realized gains and losses are computed based on the specific identification method and were not material for the periods presented. Marketable securities are used to secure the Company’s credit facility. The fair values of marketable securities were estimated using the market approach using prices and other relevant information generated by market transactions involving identical or comparable assets. The Company uses quoted market prices in active markets or quoted market prices in markets that are not active to measure fair value. When developing fair value estimates, the Company maximizes the use of observable inputs and minimizes the use of unobservable inputs.

Financial assets, measured at fair value, by level within the fair value hierarchy were as follows (in thousands):

		June 30, 2013						December 31, 2012

NOTE 6. - RESTRUCTURING CHARGE

On October 19, 2012, the Company committed to a plan intended to improve the balance between the Company’s telecommunications product expenses with the reduced revenue levels of this product line. Under the 2012 restructuring plan, the Company reduced its workforce by 10 regular full-time positions. As a result of the 2012 restructuring plan, the Company recorded a restructuring charge of $253,000, classified as an operating expense, in the fourth quarter of 2012 related to future cash expenditures to cover employee severance and benefits. During the three months ended March 31, 2013, the Company reduced its restructuring charge by $67,000 related to reduced future cash expenditures related to severance and benefits for a former employee. The former employee’s accepting other employment in April 2013 reduced the amount of severance and benefit payouts by the Company. The following table summarizes the timing of payments under the restructuring plan (in thousands):

Stockholders' Equity Note Disclosure [Text Block]

NOTE 9. - SHAREHOLDERS’ EQUITY

The Board of Directors adopted a Shareholder Rights Plan (the “Plan”) and, under the Plan, declared a non-taxable dividend, paid at the close of business on August 9, 2011 (the “Record Date”), of one common share purchase right (a “Right”) for each outstanding share of Common Stock. From the Record Date until the Rights become exercisable, the Rights will be attached to all outstanding shares of Common Stock and, therefore, will be represented by the certificates evidencing the shares of Common Stock and transferrable only with the shares of Common Stock. A Right will be exercisable, upon certain conditions, to purchase one share of Common Stock from the Company at a price of $39, subject to adjustment. The Rights will become exercisable, and separate from the shares of Common Stock, upon the earlier of:

(1) ten business days following the date of the first public announcement (the “Stock Acquisition Date”) that a person or a group of affiliated or associated persons has acquired, or obtained the right to acquire, beneficial ownership of 15% or more of the outstanding shares of Common Stock (an “Acquiring Person”), or

(2) ten business days (or such later date as the Board of Directors may determine) following the commencement of a tender or exchange offer that, if consummated, would result in a person or group of persons becoming an Acquiring Person.

Upon a Stock Acquisition Date, each holder of a Right (other than an Acquiring Person) will be entitled to receive, upon exercise of the Right, shares of Common Stock at a 50% discount. Also, if, at any time following a Stock Acquisition Date, the Company is acquired in a merger or business combination and its Common Stock is exchanged or converted, or if 50% or more of the Company’s assets, cash flow or earning power is sold or transferred, then each holder of a Right (other than an Acquiring Person) will be entitled to receive, upon exercise of the Right, shares of the acquirer’s common stock at a 50% discount. Further, at any time after a person or group of persons becomes an Acquiring Person, but before any person or group of persons becomes the beneficial owner of 50% or more of the outstanding shares of Common Stock, the Company may cause each exercisable Right to be exchanged for one share of Common Stock. The Rights will expire at the close of business on July 29, 2021, or such other date as the Board of Directors may determine under certain circumstances. The Board of Directors may terminate the Plan or cause the Company to redeem the Rights, at a price of $0.001 per Right, at any time before the earlier of a Stock Acquisition Date or the expiration of the Rights. The Company has reserved 90,315,210 shares of Common Stock for possible issuance upon exercise of Rights under the Plan.
