This Form 4 amends the Form 4 filed by the reporting person on May 19, 2015 to reflect the sale of an additional 4,856 shares to cover the reporting person's tax liability incurred upon the vesting of the reporting person's restricted shares. The Issuer's broker made the additional sale on May 21, 2015, with an effective date of May 18, 2015 and at the average price per share reported for the May 18, 2015 sales ($17.22), to correct the broker's error whereby they inadvertently undersold the number of shares required to cover the reporting person's tax liability. The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $16.69 to $17.65, inclusive. The reporting person undertakes to provide to The Rubicon Project, Inc., any security holder of The Rubicon Project, Inc., or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the ranges set forth in footnote (3 to this Form 4.
