Just days after Cadbury declared its suitor a "low growth" company with a "long history of underperformance," the British maker of Dairy Milk chocolates and Dentyne gum capitulated to a raised bid of 840 pence ($13.78) per share.

The deal, comprising 500 pence cash and 0.1874 new Kraft shares for each Cadbury share, is a 9% premium to its previous 770 pence offer and 50% higher than Cadbury's market value before Kraft, based in Northfield, Ill., went public with its approach in September.

The combination of the pair would create the world's biggest confectionary company, replacing Mars Inc., and Kraft CEO Irene Rosenfeld said the deal provides "both immediate value certainty and upside potential" as she tried to appease concerns about the loss of Cadbury's iconic status.

The company's roots go back to the grocery store opened in 1824 by John Cadbury in Birmingham, central England. A Quaker, Cadbury believed cocoa and drinking chocolate were healthy alternatives to alcohol, considered to add to the miseries of the working class.

The popular Dairy Milk bars were launched in 1905 as a challenge to dominant Swiss chocolate makers.

"We have great respect for Cadbury's brands, heritage and people," Rosenfeld said. "We believe they will thrive as part of Kraft Foods."

However, unions are worried there were no clear guarantees from Kraft that it will not switch manufacturing of some of the 186-year-old company's chocolates to eastern Europe, sacrificing thousands of British jobs.

"This is a very sad day for U.K. manufacturing. A successful, iconic, independent U.K. brand will now be owned by a giant company with massive debt," said Jennie Formby of the Unite union, which had campaigned against Kraft's offer.

The deal, one of the largest transnational takeovers since the credit crunch, is further sign that food companies are seeking to gain scale by combining, after Mars bought William Wrigley Jr. Co. in 2008 for $23 billion.

A Kraft-Cadbury combination will create a portfolio with more than 40 confectionary brands, each with annual sales in excess of $100 million.

Kraft, attracted by Cadbury's extensive reach in lucrative emerging markets, sidestepped concerns from its own major shareholders by reducing the share portion of the deal below 20%, negating the need for it to be approved by shareholders.

Billionaire investor Warren Buffett, whose Berkshire Hathaway is Kraft's biggest shareholder, voted against Kraft's proposal earlier to issue more shares to fund the takeover bid. Kraft made the proposal after raising the cash portion of its offer by selling its North America pizza business to Nestle for $3.7 billion.

Under the revised offer, Kraft will issue 265 million new shares representing approximately 18 percent of the existing issued share capital and 15 percent of the company's enlarged issued share capital.

There was surprise at the overnight change in tune from Cadbury Chairman Roger Carr, who had led a spirited defense against Kraft, talking up the British company's standalone strengths, over the past four months.

The man who earlier this week said Rosenfeld's shareholders had been forced to deal with "repeated disappointment from a management team who have promised much and delivered less," told his own shareholders that the revised deal "represents good value."
