Performance Restricted Stock Units Granted to Executive Officers, Vesting Based on Financial Performance.

On April 8, 2011, performance restricted stock units (PRSUs) were granted to John Wren, President and Chief Executive Officer of Omnicom Group Inc. (“Omnicom,” “us” or “our”), and other executives described below. The ultimate number of PRSUs received by the executives will depend upon Omnicom’s return on equity over the coming three years, as compared to the return on equity of Omnicom’s five principal competitors. Between 50% and 100% of the PRSUs will ultimately be received by the executives, depending on Omnicom’s rank as compared to such competitors.

Each PRSU represents the right to receive one share of our common stock upon vesting. The PRSUs are eligible to vest in five annual installments beginning on the one-year anniversary of the date of grant, subject to continued employment with us or our subsidiaries on the applicable date.

The PRSUs were awarded as part of the variable year-end incentive award for performance in 2010 paid to Mr. Wren, our principal financial officer and other named executive officers. The maximum number of PRSUs that each executive is eligible to receive under this award is equal to the dollar value of the equity portion of the 2010 incentive award divided by the closing price of our common stock on the date of grant (the “Maximum PRSU Award”). The maximum amount of each executive’s award is as follows:

Three years following the award, our average return on equity over calendar years 2011, 2012 and 2013 will be compared to the average return on equity for each of Omnicom’s five principal competitors for the same three-year period. Based on our rank relative to the peer group, the total number of PRSUs awarded will be adjusted by applying the Multiplier below to the Maximum PRSU Award:

After each of the first two years, the minimum number of PRSUs to which the named executive officer is entitled with respect to the applicable annual installment will be distributed on the anniversary of the award date (which will be 50% of such annual installment). After the three-year measurement period ends and Omnicom’s rank amongst its competitors is determined, any additional PRSUs earned with respect to the first three installments will then be distributed. The remaining number of PRSUs will continue to vest in years four and five such that the total number of PRSUs distributed at the end of five years equals the Maximum PRSU Award times the Multiplier.
