NAUTILUS, INC.

FORM 8-K

In a meeting held on February 16, 2012, the Compensation Committee of the Board of Directors of Nautilus, Inc. (the “Company”) approved the grant of equity compensation to certain of the Company’s executive officers. The equity grants, which are listed below, included options to purchase shares of the Company’s common stock and performance unit awards, both issued under the Company’s 2005 Long Term Incentive Plan. The options vest in three equal annual installments, beginning on February 16, 2013. The options expire on February 16, 2019. The performance unit awards vest based on achievement of certain operating income and return on asset goals established for a three year performance period. The number of shares vested under the performance unit awards following conclusion of the performance period will be determined based on the level at which the financial goals are achieved. The number of shares vesting can range from 60% of the performance unit awards if minimum thresholds are achieved to a maximum of 150%.

Additionally, the Company established award eligibility and fixed annual performance targets for the above-named officers under the Company’s short-term incentive program. The Company’s short-term incentive program focuses on achievement of certain annual goals for pre-tax operating income and net working capital, as well as personal and strategic performance goals established for the performance period.

Under the short-term incentive program, individual plan participants are eligible to receive incentive compensation based on a target percentage of their base salary. The amount payable is determined based upon the weighted average percentage achievement of the financial, personal and strategic performance goals established for the annual plan period. Achievement below 100% of goal on a combined basis results in payout of less than the target award, and achievement of greater than 100% of goal on a combined basis results in a payout of greater than the target award. The Company must achieve a minimum of 85% of its operating income and net working capital goal for any payout to be available with a maximum award of 150% of target if the goals are exceeded. For 2012, Messrs. Cazenave, McMahon, Bolio and Neal are eligible for short-term incentive compensation equal to 100%, 75%, 50%, and 60% of their base salaries, respectively.
