The Silver Lake Entities and Gartner entered into a Stock Purchase Agreement (the "Purchase Agreement") on June 17, 2004, whereby, subject to the terms and conditions therein, the Silver Lake Entities agreed to sell to Gartner and Gartner agreed to purchase from the Silver Lake Entities 9,196,065 shares of Common Stock, subject to adjustment as follows (provided that in no event will more than 12,000,000 shares of Common Stock (the "Share Cap") be purchased from the Silver Lake Entities): (a) if Gartner increases or decreases the number of shares of Common Stock subject to the Tender Offer (any such increase or decrease, the "TO Change"), the aggregate number of shares of Common Stock to be purchased by Gartner from the Silver Lake Entities will be increased or decreased, respectively, by an amount equal to the TO Change multiplied by a fraction, the numerator of which is 46,969,066 and the denominator of which is 57,707,954 (representing the shares of outstanding shares of Common Stock held of record by the Silver Lake Entities divided by the outstanding shares of Common Stock held of record by all stockholders of Gartner other than the Silver Lake Entities) and (b) if the number of shares of Common Stock tendered and accepted for payment in the Tender Offer is less than the number of shares of Common Stock Gartner is offering to purchase in the Tender Offer as of the expiration date (any such difference, the "Series A Shortfall"), the aggregate number of shares of Common Stock to be purchased by Gartner from the Silver Lake Entities shall be increased by an amount equal to the Series A Shortfall. The price per share paid by Gartner for the shares of Common Stock purchased from the Silver Lake Entities will be the same as that paid by Gartner to its other stockholders who tender shares of Common Stock pursuant to the Tender Offer. The Silver Lake Entities are not obligated to sell any shares if a minimum of 1,680,394 shares are not tendered and accepted for payment in the Tender Offer. The Silver Lake Entities agreed, pursuant to the terms of the Purchase Agreement, not to tender any of their shares of Common Stock in the Tender Offer. The Purchase Agreement is attached as an exhibit to the Schedule 13D and is incorporated herein by reference.
