Chesapeake had announced on March 11, 2002 its intention to commence the tender offer within the next few days. Chesapeake's action was based upon the representations of senior management of Canaan of their willingness to engage in good faith discussions with Chesapeake management regarding the offer in the near future together with the request by Canaan management that Chesapeake delay commencement of the tender offer until after the discussions. Aubrey K. McClendon, President and Chief Executive Officer of Chesapeake stated, "We remain committed to take our fair and full offer to the shareholders of Canaan and are pleased that Canaan's management and advisors have agreed to meet with us on this issue." McClendon cautioned, however, that Chesapeake may at any time commence or modify its proposed tender offer for Canaan shares, or terminate its tender offer plans. On March 11, 2002, Chesapeake delivered to the board of directors of Canaan its $12.00 per share cash offer, which represents an aggregate purchase price for the common stock on a fully diluted basis of approximately $55 million plus the assumption of Canaan's debt, which was approximately $42 million as of December 31, 2001. The price offered by Chesapeake represents a 31% premium over the closing price of $9.15 on March 11, 2002, the last day prior to the announcement of Chesapeake's intent to commence a tender offer, and a 58% premium over Canaan's closing stock price of $7.60 on November 26, 2001, the last trading day before Canaan's public announcement of Chesapeake's interest in acquiring Canaan.
