A low take-up had threatened to thwart plans by France's second-largest bank Credit Agricole to cement its presence in Italy's consolidating banking sector, which is its biggest foreign market.

As of Tuesday, which was due to be the second-to-last day for the offer, take-up stood at 22.6% of the shares targeted by the bid despite an improved offer price last week.

To overcome opposition from Creval and many of its investors, Credit Agricole Italia had upped the bid price to 12.20 euros a share from an initial 10.50 euros, a level which Creval shares had been consistently trading above.

It said it would pay a higher price of 12.50 euros only if acceptances topped 90% of Creval's capital, for an investment of up to 855.36 million euros ($1 billion).

However, late on Tuesday it said it was dropping this condition and set the price at 12.50 euros.

Following the decision, Credit Agricole Italia said investors holding a further 27.2% of Creval had now agreed to tender their shares or confirmed they would do so.

That includes shares held by leading Creval investor Denis Dumont, a French businessman who had bet on the Italian's bank restructuring in preparation for a sale, as well as investment funds Alta Global, Hosking Partners, TIG Advisors and Petrus Advisers, which had initially spurned the bid.

When including Tuesday's take-up and another 2.45% Creval stake bought in block trades, the Italian arm of the French bank potentially controls the majority of Creval's capital.

The bid's price is still below a range of 12.95 to 22.70 euros which Creval's board had indicated as fair based on assessments by financial advisers Mediobanca and BofA Securities.

The board had rejected the sweetened offer as still too low though it welcomed the highest price saying it came closer to minimum levels set by advisers.

Shares in Creval were up 3.8% to 12.4 euros at 1040 GMT.

Due to end on Wednesday, the buyout bid has now been extended through Friday. It is still conditional on reaching a 66.67% acceptance threshold, which can be lowered to 50% plus one share.

Intesa Sanpaolo analysts said the bid's premium was small in light of the projected benefits, but noted there was no competing offer.

"At the current conditions the offer could be successful. Tender shares," they said.

The acquisition would double Credit Agricole Italia's market share in Italy's wealthiest areas.

Credit Agricole entered Italian retail banking in 2007, buying two northern banks and adding three small failing banks a decade later, while its asset manager Amundi bought rival Pioneer from UniCredit for 3.6 billion euros.

Its latest move comes after Intesa last year snatched rival UBI in an unsolicited takeover to create a national champion with a fifth of the banking market.
