--Xstrata says 17.6%-22% premium is significantly lower than what would be expected in a takeover

--Replacement of Xstrata CEO and change in management-incentive package represents "significant risk"

--Xstrata seeks more clarity from Glencore on merger proposal

--Liberum Capital says Xstrata board unlikely to recommend offer despite Standard Life's support of improved terms

LONDON--Anglo-Swiss miner Xstrata PLC (XTA.LN) said Friday the revised offer outlined by Glencore International PLC (GLEN.LN) represents a significantly lower premium than would be expected if the deal were to be considered a takeover rather than a merger, signaling that the new offer may still fall short of approval from Xstrata's board.

Commodities titan Glencore attempted to salvage its deal from likely collapse Friday by increasing its offer to 3.05 Glencore shares for every Xstrata share just as shareholders from both companies were due to vote on the deal. The deal was largely expected to fall apart after Xstrata's second-largest shareholder, sovereign wealth fund Qatar Holding LLC, said it would vote against the original 2.8-share swap ratio on grounds that the premium wasn't enough.

The independent directors of Xstrata said Friday the latest proposal "lacks sufficient information on key elements," which prompted them to send a written letter to Glencore asking for clarification.

Xstrata's independent directors noted that the revised share-swap ratio represents a 22% premium to Thursday's closing share price and a 17.6% premium to the undisturbed Xstrata share price Feb. 1, the day before news of talks between the two began to surface. They noted, however, that this is "significantly lower than would be expected in a takeover."

Glencore and Xstrata's plan to create a mining behemoth, with a market capitalization of more than $70 billion, based on current share prices, faced strong opposition from shareholders including Qatar Holding, Knight Vinke and Standard Life.

The new proposal contains a condition that aims to give Glencore the ability to structure the transaction as a takeover offer instead of a recommended scheme of arrangement, a power that currently resides with Xstrata.

Such ability to switch the transaction to a takeover from the current merger-of-equals scheme would lower the shareholder vote-approval threshold to 50% from 75%, thereby making it easier for Glencore to secure Xstrata's shareholder approval for the deal.

Under the current merger of equals, Glencore, Xstrata's largest shareholder with a 34% stake, isn't allowed to vote, but under a takeover structure, it would be allowed to vote on such a transaction.

Xstrata also said Glencore's new proposal to install its chief executive, Ivan Glasenberg, as CEO of the combined company--he was to become deputy CEO under Xstrata chief Mick Davis--and amend the management-incentive arrangements "represents significant risk" in terms of retaining Xstrata's senior and operational management, who are set to be responsible for assets that generate about 80% of the combined group's earnings, according to the original terms of the deal.

Standard Life Investments, which initially opposed the deal, said in a statement Friday it was supportive of the improved terms. "We are pleased with the proposed outcome," said David Cumming, head of equities at Standard Life.

But a top-30 shareholder who wished not to be named because he was still digesting the news said, "There are still too many unanswered questions" about the revised offer, including whether the new proposal is a merger or a takeover. He said if it is a takeover, he would have to consider carefully the premium being offered and said there are questions about what would happen to Xstrata's Davis under the new structure.

"It looked pretty clear to me [from the beginning that]...Ivan was going to be running the show, but what it means for Mick," now that Mr. Glasenberg will be the new CEO of the combined entity, remains to be seen, he said.

Mining analyst Richard Knights of Liberum Capital said he doubted Xstrata's board would recommend the offer.

"It looks unlikely that Xstrata's board will recommend Glencore's revised offer based on the statement they released," he said.

Glencore's shares closed down 3.6% at 378 pence a share, while Glencore's shares closed up 3.6% at 1,014 pence a share.
