UPDATE 1-IAC offers to buy rest of Meetic for 15 euros/share

* Meetic shares suspended at company's request

* IAC does not aim to delist company

* Offer values whole company at 347 mln euros

PARIS, May 30 (Reuters) - IAC/InterActiveCorp's Match.com unit offered on Monday to buy all outstanding shares of French online dating service Meetic for 15 euros a share in a bid to further align the companies' objectives.

Match.com, which already owned 27 percent of Meetic and with whom it had previously merged its European business, said Meetic founder and Chief Executive Marc Simoncini had agreed to sell about 3.7 million shares into the tender offer.

That is equivalent to 16 percent of Meetic's outstanding shares. Simoncini will retain 1.6 million, or about 7 percent, of the company's outstanding shares, and will remain on Meetic's board, IAC said in a statement.

Match.com said it does not plan to delist Meetic after completion of the offer, which values the entire company at about 347 million euros ($497 million).

Meetic shares were suspended from trading at the company's request, NYSE Euronext said.

The offer is 11.6 percent higher than Meetic's closing price on Friday, but the premium left some investors less than enthusiastic.

"At very first glance, the offer doesn't look very appealing -- 7.3 times EV/EBITDA, PE ratio 13.9 times," said one Paris-based trader.

"But as Mr. Simoncini will tender 16 percent of the capital and as the U.S. group does not want to delist Meetic, we believe there are few incentives for Match to raise its bid price, even if some minorities will probably be unhappy with the outcome."
