(1) On May 12, 2006, The Anschutz Corporation entered into a forward sale contract (the "Contract") that relates to an aggregate of 384,925 shares of common stock. The Contract provides that The Anschutz Corporation will deliver on each of six days in 2009 (each such day is referred to herein as a "Settlement Date"), a number of shares of common stock equal to (i) the applicable Base Amount (as hereinafter defined), and (ii) the applicable Exchange Rate, which will be determined as follows:
(2) (a) If the closing price (the "Settlement Price") of the common stock on the relevant Valuation Date (as hereinafter defined) is less than or equal to $38.9687 (the "Forward Floor Price"), the Exchange Rate will be one; (b) If the Settlement Price is greater than the Forward Floor Price but less than or equal to $54.5562 (the "Forward Cap Price"), the Exchange Rate will be equal to the Forward Floor Price divided by the Settlement Price; and (c) If the Settlement Price is greater than the Forward Cap Price, the Exchange Rate will be equal to the Adjusted Forward Floor Price (as hereinafter defined) divided by the Settlement Price. The Adjusted Forward Floor Price will be equal to the Forward Floor Price plus the Settlement Price minus the Forward Cap Price.
(3) The "Base Amount" for each of the first five Settlement Dates equals 64,000, and for the last settlement date equals 64,925. The Valuation Date for each Settlement Date is set forth in Column 6 of Table II of this Form 4 under "Expiration Date."
(4) In consideration therefor, The Anschutz Corporation will receive on May 17, 2006 an aggregate prepayment amount of $12,314,347. In the event of the payment of dividends (whether cash or in-kind), stock splits, reverse stock splits, spinoffs, mergers or similar events affecting the common stock, the Base Amounts and one or more of the Settlement Price, Forward Floor Price and Forward Cap Price are subject to adjustment depending on the nature of the transaction. The Anschutz Corporation has pledged 384,925 shares of common stock to secure its obligations under the Contract.
(5) Philip F. Anschutz owns 100% of the capital stock of Anschutz Company, which owns 100% of the capital stock of The Anschutz Corporation. The Anschutz Corporation is the registered owner of the securities indicated.
