PLAN OF DISTRIBUTION Interpublic has not been advised by the selling stockholders as to any plan of distribution. Distribution of the common stock by the selling stockholders, or by pledgees, donees (including charitable organizations), transferees or other successors in interest, may be effected from time to time in one or more transactions (which may involve block transactions): - on the NYSE in transactions that may include special offerings and exchange distributions pursuant to and in accordance with the rules of such exchange, - in the over-the-counter market, or - in transactions otherwise than on such exchange or in the over-the-counter market, or in a combination of any such transactions. Such transactions may be effected by the selling stockholders at market prices prevailing at the time of sale, at prices related to such prevailing market prices, at negotiated prices or at fixed prices. The selling stockholders may effect such transactions by selling the common stock to or through broker-dealers, and such broker-dealers may receive compensation in the form of discounts or commissions from the selling stockholders and may receive commissions from the purchasers of the common stock for whom they may act as agent. The selling stockholders may agree to indemnify any broker-dealer or agent that participates in transactions involving sales of the shares against certain liabilities, including liabilities arising under the Securities Act. We have agreed to bear certain expenses (excluding any underwriting fees, expenses, discounts or other costs payable to any underwriter, broker or dealer) in connection with the registration and sale of the common stock being offered by the selling stockholders, estimated to be approximately $44,000. We have agreed to indemnify the selling stockholders against certain liabilities, including certain liabilities under the Securities Act. The selling stockholders and any broker-dealers or agents that participate with the selling stockholders in the distribution of the common stock may be deemed to be "underwriters" within the meaning of the Securities Act, and any commissions received by them and any profit on the resale of any common stock purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act.
