Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer. 2004 Employment Agreement and Related Agreements In connection with a Second Amended and Restated Employment Agreement that Mr. Essig and the Company entered into in July 2004, the Company granted Mr. Essig a non-qualified stock option to purchase 250,000 shares of common stock and an award of fully vested 750,000 restricted units in the form of contract stock ("Restricted Units"). Under the employment agreement, Mr. Essig is also entitled to an annual option grant of between 100,000 and 200,000 shares as determined by the Company's compensation committee. The exercise price of each option grant is at fair market value on the date of grant, and the option term is ten years. Each option grant vests in accordance with the following schedule subject to Mr. Essig's continued employment: one-fourth of the shares become exercisable upon the one-year anniversary of the grant, and the remaining shares vest monthly with respect to 1/36th on the first business day of each following month. The option grants contain typical acceleration provisions in the event of a change in control of the Company, termination of employment without cause by the Company or termination of employment by Mr. Essig for a good reason. The Second Amended and Restated Employment Agreement, the Stock Option Grant and Agreement relating to the option to purchase 250,000 shares of common stock and the form of Stock Option Grant and Agreement for Mr. Essig's annual option grants are set forth as Exhibits 7(a), 7(f) and 7(h), respectively, hereto and incorporated by reference herein. Each Restricted Unit represents the right to receive one share of the Company's common stock. The shares of the Company's common stock underlying the Restricted Units ("Unit Shares") generally shall be delivered to Mr. Essig on the first business day following his termination of employment or retirement, or earlier if a change in control of the Company occurs or Mr. Essig becomes subject to taxation on any Restricted Units before the scheduled delivery date (or deferral date, if applicable). However, unless previously delivered, if Mr. Essig's employment with the Company is terminated for cause or Mr. Essig voluntarily leaves his employment with the Company prior to December 31, 2009 (other than for good reasons or due to disability), then the Unit Shares will not be distributed to Mr. Essig until the first business day of the calendar year 2017. Additionally, Mr. Essig has a one-time right to defer the delivery of the Unit Shares so long as such election is (a) made at least 12 months prior to the otherwise applicable delivery date and (b) the deferral delivery date is at least five years beyond the scheduled delivery date, but not beyond June 30, 2029. The Contract Stock/Restricted Units Agreement relating to this grant is set forth as Exhibit 7(g) hereto and incorporated by reference herein. 2000 Restricted Unit Issuance Mr. Essig received a restricted unit award in 2000 that entitles him to receive an aggregate 1,250,000 shares of common stock. Of the 1,250,000 shares, 750,000 shares are deliverable on January 6, 2006, and the remaining 500,000 shares of common stock are deliverable on March 4, 2008. The Restricted Units Agreement relating to this grant is set forth as Exhibit 7(e) hereto and incorporated by reference herein. Registration Rights The Company has also granted Mr. Essig registration rights with respect to the shares of common stock underlying his option and Restricted Unit grants. These registration rights provisions are set forth as Exhibits 7(i), 7(j) and 7(k) hereto and incorporated by reference herein. Sale Plans Under Rule 10b5-1 Mr. Essig has entered into two sales plans pursuant to Rule 10b5-1 under the Act with a registered broker-dealer. One plan provides for the sale of 340,000 shares of the 750,000 shares of common stock underlying Restricted Units and issuable to Mr. Essig on January 3, 2006. The other plan provides for the sale of up to 200,000 shares of common stock underlying options (and the exercise of the related options) at specified prices. Variable Forward Sale Agreement Mr. Essig has entered into a variable forward sale agreement with Credit Suisse First Boston Capital LLC ("CS First Boston") pursuant to which CS First Boston may sell 500,000 shares of common stock owned by Mr. Essig. The agreement requires Mr. Essig to deliver to CS First Boston on March 28, 2013 between 264,550 and 500,000 shares of common stock or the cash equivalent of such shares at the election of Mr. Essig. The amount of shares or cash equivalent will depend upon the average price of the common stock in the 20 trading days prior to and including the settlement date. In connection with this agreement, Mr. Essig pledged 500,000 shares of common stock to CS First Boston. Mr. Essig retains voting power with respect to these shares pending the settlement of this contract. Item 7. Material to be Filed as Exhibits.
