Blackstone Group has submitted a preliminary and indicative offer to Dell's special committee, which is exploring alternatives to the $24.4 billion takeover offer by Michael Dell and Silver Lake, according to a person familiar with the matter.

The details of Blackstone's offer were not immediately clear. Blackstone declined to comment.

A spokesman for Dell, the world's No. 3 PC maker, could not immediately be reached for comment.

It was not immediately clear if other parties also submitted offers for Dell.

Blackstone also is making an aggressive push to recruit Oracle (ORCL) resident Mark Hurd to be chief executive of Dell, a person familiar with the situation said on Wednesday.

The New York-based private equity firm conducted due diligence on Dell ahead of the March 22 expiration of a so-called "go-shop" period that offers interested parties the opportunity to outbid a consortium led by founder Michael Dell and Silver Lake Partners that has agreed to take the company private for $24.4 billion.
