2011 EQUITY INCENTIVE PLAN PERFORMANCE RESTRICTED STOCK UNIT AWARD TERMS

1. Grant. The Company hereby grants to the Employee an award of Restricted Stock Units (“RSUs”), as set forth in the Notice of Grant, subject to the terms and conditions in this Agreement and in the Company's 2011 Equity Incentive Plan (the “Plan”). Initially capitalized terms herein shall have the meanings set forth in the Plan or as defined herein, as applicable.

2. Company's Obligation. Each RSU represents the right to receive a Share on the vesting date. Unless and until the RSUs vest, the Employee will have no right to receive Shares under such RSUs. Prior to actual distribution of Shares pursuant to any vested RSUs, such RSUs will represent an unsecured obligation of the Company, payable (if at all) only from the general assets of the Company.

3. Vesting Schedule; Assumption or Substitution Calculation. The RSUs shall vest as follows:

Up to the Maximum Amount will vest and be settled, based upon the extent, if any, to which the performance metric has been achieved. The performance metric is the relative performance of Company stock against the Russell 2000 index over a three-year period, with the target Company stock performance equivalent to the performance of the Russell 2000 index over such period. To determine relative performance, the baseline metrics are the 90 trading day average closing price of the Company and the Russell 2000 Index, as reported in The Wall Street Journal, or such other reliable source as is determined by the Administrator, in its sole discretion, with the last of the 90 trading days falling on November 14, 2012. This 90 day average establishes both the Company baseline stock price (the “Company Baseline Stock Price”) and the Russell 2000 Index baseline (the “Russell 2000 Baseline”) against which future Company stock and Russell 2000 Index performance will be compared.

Next, the Company will measure the 90 trading day average closing price of the Company and the Russell 2000 Index, as reported in The Wall Street Journal, or such other reliable source as is determined by the Administrator, in its sole discretion, with the last trading day of such 90-trading day period ending on November 13, 2015 (establishing both the “Company Closing Price” and the “Russell 2000 Index Closing Price”).

The Company will then measure Company performance by dividing the Company Closing Price by the Company Baseline Stock Price, with the quotient expressed as a percentage of the Company Baseline Stock Price (the “Company Percentage Performance”). The Company will then measure Russell 2000 Index Performance over the same period by dividing the Russell 2000 Index Closing Price by the Russell 2000 Index Baseline with the quotient expressed as a percentage of the Russell 2000 Index Baseline (the “Russell 2000 Index Percentage Performance”).

The Company will then subtract the Russell 2000 Index Percentage Performance from the Company Percentage Performance, then add 100 to the result, with the final result constituting the relative Company performance as a percentage (the “Relative Performance Percentage”).

If the Relative Performance Percentage is 50% or less, no RSUs shall vest. If the Relative Performance Percentage equals 51%, then 2% of the Target Amount shall vest. If the Relative Performance Percentage equals 70%, then 40% of the Target Amount shall vest. If the Relative Performance Percentage equals 100%, then the Target Amount shall vest. If the Relative Performance Percentage equals 150% or more, then 200% of the Target Amount shall vest (i.e., the Maximum Amount shall vest). Relative Performance Percentages shall result in incremental vesting on a straight-line basis within tiers based on full percentage Relative Performance Percentages as set forth below:

The Company Closing Price shall be automatically adjusted to account for any Company stock split or similar change in capitalization effected without receipt of consideration by the Company set forth in Plan Section 19(a) in the same manner as set forth in Plan Section 19(a). In making determinations of the number of Shares that vest hereunder, all Relative Performance Percentage fractional percentages and Share numbers below .5 shall be rounded down to the nearest whole percentage or Share number, respectively and all Relative Performance Percentage fractional percentages and Share numbers of .5 or greater shall be rounded up to the nearest whole percentage or Share number, respectively. All vesting and delivery of Shares hereunder, except pursuant to assumed or substituted awards in a change of control as specified in the following paragraph, shall be subject to the prior written or electronic certification of the Compensation Committee of the Board as to the extent to which the applicable performance milestones have been achieved.

In the event the Company is acquired in a merger or asset sale pursuant to which this RSU is assumed or substituted pursuant to Plan Section 19(c) (a “Change of Control”), then if the performance period has not been completed as of the date of the Change of Control, the Company Closing Price shall be deemed to be the price per share received by the Company's stockholders in the Change of Control. Relative performance for such uncompleted performance period shall then be measured against the Russell 2000 Index performance from the Russell 2000 Index Baseline through the 90 trading day average closing price of the Russell 2000 Index in the period ending on the date of the Change of Control. The Company's stock performance relative to the Russell 2000 Index shall then be determined consistently with the methodology specified herein for completed performance period. The number of Shares subject to this RSU so determined shall then continue to vest based upon Employee's continuing as a Service Provider to the Company, the acquirer, or their Parents or Subsidiaries through November 13, 2015, subject to accelerated vesting as set forth in the Company's Change of Control Severance Plan (but only for participants in such plan), as amended from time to time.

1. Forfeiture upon Termination as an Employee. Notwithstanding any contrary provision of this Agreement or the Notice of Grant, if the Employee terminates service as a Service Provider for any or no reason prior to vesting, the unvested RSUs awarded by this Agreement will thereupon be forfeited at no cost to the Company, subject to accelerated vesting as set forth in the Company's Change of Control Severance Plan (but only for participants in such plan), as amended from time to time.

The Employee may elect to satisfy any such statutory minimum tax withholding requirement by having the Company withhold Shares otherwise deliverable to the Employee or by delivering to the Company already-owned Shares, subject to the absolute discretion of the Company to disallow satisfaction of such withholding by the delivery or withholding of stock.

4. Rights as Stockholder.

d. Employee waives any and all rights to compensation or damages as a result of the termination of employment with the Company for any reason whatsoever insofar as those rights result or may result from:
