| (1) | Each performance share represents a contingent right to receive a restricted stock unit upon MPWR's common stock achieving a 20-day average closing price of $40.00 per share from January 1, 2014 through December 31, 2018 (the "Performance Period"). Credited performance units are still subject to an additional, quarterly, five-year time-based vesting schedule beginning January 1, 2019, subject to acceleration under certain circumstances. |
| (2) | Each performance share represents a contingent right to receive a restricted stock unit upon MPWR's common stock achieving a 20-day average closing price of $43.00 per share from January 1, 2014 through December 31, 2018 (the "Performance Period"). Credited performance units are still subject to an additional, quarterly, five-year time-based vesting schedule beginning January 1, 2019, subject to acceleration under certain circumstances. |
| (3) | Transaction was executed during an authorized trading window in compliance with the Company's Insider Trading Compliance Program. |
| (4) | The price is the weighted average sale price for the transactions reported on this line. The prices for the transactions reported on this line range from $46.80 to $46.802. The reporting person undertakes to provide, upon request by the staff of the Securities and Exchange Commission, the issuer, or a security holder of the issuer, full information regarding the number of shares sold at each separate price. |
| (5) | The reporting person was granted 43,200 performance units on December 14, 2013. Each performance unit vests as stated: one share of MPWR common stock will be credited for each performance unit if the price of MPWR common stock achieves a 20-day average closing price of $40.00 per share from January 1, 2014 through December 31, 2018 (the "Performance Period"), and up to four additional shares will be credited for each performance unit if the 20-day average closing price reaches $43.00, $47.00, $52.00, and $56.00 (one share per price level) during the Performance Period. Credited performance units are subject to an additional, five-year, quarterly, time-based vesting schedule beginning January 1, 2019, subject to acceleration under certain circumstances. The derivative securities reported in columns 5 and 9 reflect the maximum payout achievable. If the Company does not achieve a price threshold within the Performance Period, 1/5 of the reported derivative securities will be forfeited. |
| (6) | Each performance unit will vest as follows: one share of MPWR common stock will be credited for each performance unit if the price of MPWR common stock achieves a 20-day average closing price of $40.00 per share from January 1, 2014 through December 31, 2018 (the "Performance Period"), and up to four additional shares will be credited for each performance unit if the 20-day average closing price reaches $43.00, $47.00, $52.00 and $56.00 (that is, one share per price level) during the Performance Period. Credited performance units are then subject to an additional, quarterly, five-year time-based vesting schedule beginning January 1, 2019, subject to acceleration under certain circumstances. |
| (7) | No new grants are being reported by this amendment. This amendment merely increases the number of derivative securities originally reported in column 5 and 9 of Table II of the Form 4 filed with the SEC on December 18, 2013 to match the number of shares underlying the derivative security originally reported in column 7 of Table II. These changes are needed to allow the Company to utilize its existing Section 16 filing program to report the vesting of the performance units when the different price thresholds are achieved. The Company's existing filing program does not allow for the reporting of vesting of performance units that entitle a grantee to a potential payout under those units greater than 1x. |
