Ophir offered to buy Salamander on Friday, proposing 0.5719 shares for every Salamander share in a deal which would leave Salamander shareholders owning around 21 percent of Ophir.

"The board of Salamander unanimously believes that the Ophir offer represents an attractive opportunity to participate in an enlarged African-Asian exploration and production company with a strong balance sheet and enhanced operating capability," Salamander's chairman Charles Jamieson said on Monday.

The agreed deal follows several weeks of speculation around Salamander before rival bidder Spain's CEPSA walked away earlier in November.
