Mr. Plank’s brother is J. Scott Plank, our Senior Vice President of Retail.

In September 2003, we entered into a registration rights agreement and stockholder agreement with Rosewood Capital IV, L.P. and Rosewood Capital IV Associates, L.P., whose general partner is Rosewood Capital Associates IV, L.L.C., and for whom Byron K. Adams, Jr., one of our directors, is a managing member, as well as with Kevin A. Plank, who is our President, Chief Executive Officer and Chairman and our principal stockholder, J. Scott Plank, Kip Fulks and Ryan Wood, who are executive officers of the Company, Plank Investments Limited Partnership and our other stockholders. These agreements are described under “Compensation Committee Interlocks and Insider Participation” above. The stockholder agreement terminated in accordance with its terms upon the completion of our initial public offering in November 2005.

In 2005, we had life insurance policies on Kevin A. Plank and J. Scott Plank in the amount of $16.0 million and $4.4 million, respectively, for which we were the named beneficiary. These policies were acquired by us pursuant to the terms of buy-sell agreements that we entered into on September 30, 2003. The agreements provided that we would maintain this level of life insurance for so long as we are able to do so on economically reasonable terms. In the event of the executive’s death, we were obligated to use the entire proceeds from the insurance policy to purchase from the executive’s estate as much of our common stock that it held as we could at the higher of the then fair market value or book value, and the executive’s estate was obligated to sell that common stock to us. The premiums on these policies were $589.43 per month and $233.53 per month, respectively. These agreements terminated in accordance with their terms upon the completion of our initial public offering in November 2005.

We also maintained life insurance policies on Ryan Wood and Kip Fulks in the amount of $2.5 million each, for which we were the named beneficiary. These policies were acquired by us pursuant to the terms of amended and restated buy-sell agreements that we entered into with Messrs. Wood and Fulks on September 30, 2003. The agreements were substantially similar to those described above, except that they also provided that in the event of the termination of the executive’s employment, we had an option for 90 days to purchase all of the shares of our common stock that he then held, unless the termination of his employment was by us without cause or by him for good reason, in which case our option was only with respect to 50% of the shares of our common stock that he then held. The premiums on these policies were $104.42 per month and $100.11 per month, respectively. These agreements terminated in accordance with their terms upon the completion of our initial public offering in November 2005.

In 2001, each of Ryan Wood and Kip Fulks issued a promissory note to us in the principal amount of $56,000 in connection with the exercise of employee stock options to purchase an aggregate of 2.4 million shares of our common stock. The promissory notes bore interest at 5.5% per annum and were to mature on February 1, 2006. The notes were repaid in December 2005, with proceeds these officers received from the initial public offering.

Thomas J. Sippel, one of our directors, is a partner in a law firm utilized by the Company. In 2005, the Company paid approximately $330,000 to this law firm for legal services performed.
