LONDON (AP) – Britain’s Royal Opera House has declared troubled philanthropist Alberto Vilar in breach of a multimillion-dollar pledge that saw the company put his name on its flagship building. It gave him 60 days to resume payments.

It is the latest sour note in the relationship between Britain’s leading opera house and the Cuban-born financier, who was arrested in New York in May on charges of business fraud.

On Tuesday, a new charge of conspiring to commit securities fraud and a second count of wire fraud were added to the federal case brought in Manhattan against the philanthropist.

In its statement, the Royal Opera House said Vilar was in “material breach” of his 1999 pledge of $17 million to the company’s development fund. In return for the donation, the company renamed its Floral Hall – an iron and glass-roofed atrium overlooking London’s Covent Garden market – the Vilar Floral Hall.

Opera spokesman Christopher Millard said Wednesday that no decision had been made on removing Vilar’s name from the building. “Obviously, we’re taking legal advice,” he said.

Millard said Vilar had given the company $5 million of the promised redevelopment money and had not made a payment since March 2002.

“We have renegotiated the schedule of payments on several occasions,” said the July 13 statement issued by the chair of the opera’s trustees, Dame Judith Mayhew Jonas. “However, he has consistently failed to reach these new deadlines and in doing so is in breach of all agreements.”

The statement said that if Vilar did not resume payments within 60 days, “the ROH will then be entitled to notify Mr. Vilar that the agreement is terminated.”

Last month the company dropped Vilar’s name from its young artists’ program, saying he had fallen behind on promised payments.

Vilar, who Forbes magazine once said was worth $950 million, tried to build a legacy of opera sponsorship with the fortune he earned and lost in the rise and fall of the 1990s dot-com era.

The financier spent an estimated $225 million adorning opera houses throughout the world with his name. Besides the $17 million he donated to the Royal Opera House, Vilar gave $20 million to the Metropolitan Opera in New York and $14 million to St. Petersburg’s Kirov Opera.

The new indictment on Tuesday combines charges against Vilar with those against Gary Alan Tanaka, a founder along with Vilar of Amerindo Investment Advisors.

Prosecutors say Vilar and Tanaka cheated an investor in their firm out of $5 million, which they spent on personal expenses and contributions to such entities as the American Academy in Berlin and Vilar’s alma mater, Washington & Jefferson College.

Jeff Hoffman, a lawyer for Vilar, and Eric Creizman, a lawyer for Tanaka, did not immediately return telephone messages for comment on Wednesday.

The charges in the case first brought nearly two weeks ago carry potential penalties of more than 10 years in prison.
