        <footnote id="F1">Represents the amount of shares delivered to satisfy applicable tax withholding obligations in connection with the vesting of shares of restricted stock.</footnote>
        <footnote id="F2">Shares are restricted stock and vest in three equal annual installments beginning on March 17, 2018.</footnote>
        <footnote id="F3">Each performance right represents a contingent right to receive one share of common stock of NN, Inc. (the &quot;Issuer&quot;).</footnote>
        <footnote id="F4">The vesting of the performance rights is based on the relative total shareholder return (&quot;TSR&quot;) of the Issuer, as compared to the TSR of the S&amp;P SmallCap 600 Index over the period beginning on January 1, 2017 and ending December 31, 2019. The performance rights will vest on December 31, 2019 subject to the reporting person's continuous employment through December 31, 2019 and subject to certain conditions as set forth in the Issuer's 2016 Omnibus Incentive Plan. Performance rights granted represent the right to receive the target shares, and actual performance rights earned may be between 50% and 150% of the target shares. Performance rights that do not vest on December 31, 2019 expire automatically.</footnote>
