| ·   | The Company must have positive non-GAAP net income before any of the following operating metrics-based elements would apply. Non-GAAP operating income excludes share-based compensation, including ESOP (as defined below) expenses, acquisition-related charges, restructuring charges, amortization of acquired intangibles and impairment charges. |
|--------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | 2012 published non-GAAP operating income was $5.2 million (which figure excludes share-based compensation, including ESOP expenses, acquisition, restructuring and impairment related charges, amortization of acquired intangibles and discontinued operations). |
|--------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | Revenue - For each percent that revenues are above or below the annual operating plan of $123.5 million, an executive's revenue-related variable compensation target will be increased or reduced by ten (10) percent. The amount cannot be less than zero and is subject to the aggregate limitation in Section 3 of the plan, such that an executive’s total variable compensation cannot exceed more than 200% of that executive’s position target. |
|--------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

----

| ·   | Non-GAAP revenues were $107.2 million, which consisted of reported revenues from continuing operations of $100.2 million, revenues from discontinued operations of $3.0 million and IP revenue of $4.0 million from the license agreement with Entropic accounted for as part of the gain from sale of the PHY business, and were below the minimum threshold of $111.2 million and therefore, no variable compensation was attained for the revenue portion of the financial metrics for 2012.  Revenue from discontinued operations and the license revenue from the Entropic agreement were included in calculation of revenue attainment as these items were included in the annual operating plan used to set the financial metrics. |
|--------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | Gross Margin - For each percentage point that gross margin is above or below the annual operating plan of 56.3%, an executive's gross margin-related variable compensation target will be increased or reduced by forty (40) percent. The amount cannot be less than zero and is subject to the aggregate limitation in Section 3 of the plan, such that an executive’s total variable compensation cannot exceed more than 200% of that executive’s position target. |
|--------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | Non-GAAP gross margin was 59.1%, which included revenue and gross profit from continuing operations, discontinued operations and the license agreement with Entropic, which was accounted for as part of the gain from sale of the PHY business.  Revenue and gross profit from discontinued operations and the license revenue from the Entropic agreement were included in calculation of gross margin attainment as these items were included in the annual operating plan used to set the financial metrics. |
|--------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | Non-GAAP Spending - For each percent that non-GAAP spending is above or below the annual operating plan of $70.0 million, an executive's revenue-related variable compensation target will be reduced or increased by twenty (20) percent. The amount cannot be less than zero and is subject to the aggregate limitation in Section 3 of the plan, such that an executive’s total variable compensation cannot exceed more than 200% of that executive’s position target. Non-GAAP spending excludes share-based compensation, including ESOP (as defined below) expenses, acquisition-related charges, restructuring charges, amortization of acquired intangibles and impairment charges. |
|--------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| ·   | Non-GAAP spending was $67.7 million, which consisted of reported non-GAAP operating expense of $53.7 million and non-GAAP spending for discontinued operations of $14.0 million.  Reported non-GAAP operating expense excludes share-based compensation, including ESOP (as defined below) expenses, acquisition-related charges, restructuring charges, amortization of acquired intangibles, impairment charges and expenses from discontinued operations.  The discontinued operations expenses were added back to the reported non-GAAP operating expense for the calculation of non-GAAP spending attainment as these costs were included in the annual operating plan used to set the financial metrics. |

| ·   | Group goals (20% Weight): Each functional group had measurable objectives for the year, some predetermined at the beginning of the year and some adjusted due to the activities associated with divestitures and the then pending IDT merger which was subsequently terminated.  If a functional group met all of their objectives, the executive officer within the functional group earned the full 20% of their variable compensation target. In cases where an executive officer did not achieve one (1) or more objectives, they only received credit for the objectives achieved. An executive could not receive more than 100% of their target variable compensation for personal objectives and could not receive more than 200% of their target variable compensation in any event. |

|  (2) | These dollar amounts reflect the aggregate grant date fair value of option awards in the years indicated in accordance with FASB ASC Topic 718.  Therefore, these amounts do not represent payments actually received by the officers.    The actual value, if any, that an NEO may realize from a stock option is contingent upon the satisfaction of the conditions to vesting in the option and upon the excess of the market price of the Company’s common stock over exercise price, if any, on the date of exercise and there is no assurance that the value, if any, eventually realized by the NEO will correspond to the amount reported. |

The actual value that an NEO may realize from an RSU is contingent upon the satisfaction of the conditions to vesting in the RSU and the market price of the Company’s common stock on the date of release and there is no assurance that the value eventually realized by the NEO will correspond to the amount reported. |

| (4) | The dollar amounts in 2012 and 2010 represent compensation earned under the 2012 and 2010 Variable Compensation Plans, respectively.  No variable compensation was earned under the 2011 Variable Compensation Plan. For the 2010 variable compensation earned, $1.3 million of the aggregate $1.38 million was paid out on January 31, 2011. The remaining $80 thousand was deferred in which 50% of the deferral was paid out on January 31, 2012 and the final 50% was paid on January 31, 2013 for all officers except Mr. Schmitt. The final payout of $7,541 which was deferred until January 31, 2013 for Mr. Schmitt was forfeited as he was not entitled to receive any remaining unpaid bonus otherwise payable after his resignation |

| (1) | The amounts shown represented potential cash payouts under the 2012 Variable Compensation Plan adopted April 2, 2012, effective for 2012.  Under this plan, the target metrics for the 2012 variable compensation calculations are based on financial and individual objectives. Each named executive officer’s variable compensation amount is based upon attainment of our 2012 Annual Operating Plan GAAP operating income, annual revenue plan and the achievement of group or functional goals and individual objectives. The amounts that can be received under the plan range from $0, as set forth in the "Threshold" column, to the amounts set forth in the "Maximum" column. For the actual cash awards under the 2012 Variable Compensation Plan, see the amounts reported in the “Non-Equity Incentive Plan” column of the Summary Compensation Table above. Additional information concerning the Non-Equity Incentive Plan is provided under “Compensation Discussion and Analysis.” |

The share amounts for executive officers in the table above include shares allocated to the accounts of such executive officers in the Company’s employee stock ownership plan (“ESOP”).  Each ESOP participant has the right to direct the ESOP trustee to vote the shares allocated to his or her account on all matters on which holders of common stock are voting and, consequently, as to shares allocated to the account of an executive officer in the ESOP, the executive officer may be deemed the beneficial owner of such shares. |
