Chalone Wine Group ( CHLN) rose 13% after the company agreed to accept Domaines Barons de Rothschild's latest buyout offer worth $11.75 a share. Rothschild, which already owns about 49% of Chalone, had originally offered Chalone $9.25 a share in May for the rest of the shares it did not already own, but the offer was extended several times, as Chalone weighed its options and discussed alternatives to the Rothschild offer. As part of the $11.75 a share offer, Chalone is free to continue soliciting acquisition proposals from third parties at a higher price. If Chalone finds a suitor willing to pay more than $11.75 a share, Rothschild has agreed to either match the price or vote its shares in favor of the more lucrative deal. Shares of Chalone traded up $1.35 to $11.69.
