Talisman Energy Inc. (TSX:TLM)(NYSE:TLM) is pleased to announce that it has entered into a definitive agreement (the "Arrangement Agreement") with Repsol S.A. under which Repsol will acquire all of the outstanding common shares of Talisman for US$8.00 (C$9.33) per share in cash.

The purchase price for the common shares represents a 75% premium to the 7-day volume weighted average share price and a 60% premium to the 30-day volume weighted average price. Total transaction value is approximately US$13 billion, including Talisman's current debt. In addition, under the transaction, Talisman will be allowed to pay aggregate cash dividends of US$0.18 per common share prior to closing, including the dividend declared and payable on December 31, 2014.

The combination of the two companies creates a global E&P company with improved scale, enhanced capabilities and more attractive opportunities for future growth. The combined company will possess the financial flexibility necessary to maximize the value of Talisman's large undeveloped resource base.

"This deal creates significant and immediate value for Talisman stakeholders," said Chuck Williamson, Chairman of Talisman's Board of Directors. "Importantly, the deal underscores Repsol's strong belief in the high quality portfolio that Talisman has worked hard to develop. Repsol is a world-class operator with a solid track record and the financial capability to continue the development of these assets within their international portfolio. I am proud of the company that our employees, past and present, have built and I believe this transaction represents new opportunities for them in Canada and around the world."

Antonio Brufau, Chairman of Repsol, said, "Our combination with Talisman allows us to align our highly complementary portfolios of upstream assets to create a truly global company well-positioned to grow production and reserves. Talisman has strong operational capability, a highly skilled work force and we look forward to leveraging their expertise as we partner to create a stronger, more profitable and competitive organization."

Additional Information on the Transaction

The transaction is to be effected pursuant to an arrangement under the Canada Business Corporations Act. The Arrangement Agreement between Talisman and Repsol provides for, among other things, a non-solicitation covenant on the part of Talisman, subject to customary "fiduciary out" provisions, that entitles Talisman to consider and accept a superior proposal if Repsol does not match the superior proposal. If the Arrangement Agreement is terminated in certain circumstances, including if Talisman enters into an agreement with respect to a superior proposal, Repsol is entitled to a termination payment of US$270 million.

Completion of the transaction is subject to customary closing conditions, including court approval of the Arrangement Agreement, approval of two-thirds of the votes cast by holders of common shares at the special meeting, and applicable government and regulatory approvals. The transaction is targeted to close in the second quarter of 2015.

Under the Arrangement Agreement, if approved by the holders in a separate class vote, Repsol will acquire the outstanding preferred shares of Talisman. However, closing of the Arrangement Agreement is not conditioned on approval by the holders of the Talisman preferred shares.
