UPDATE 1-Sun Micro stands by leadership team

* Sun says ‘committed’ to leadership team, growth strategy

* Sun’s comments come after collapse of talks with IBM

BOSTON, April 6 (Reuters) - Sun Microsystems Inc JAVA.O said it stood by its leadership team, led by Chief Executive Jonathan Schwartz, a day after the collapse of talks to sell the high-end server maker to IBM IBM.N.

Sun issued the statement on Monday amid speculation that Schwartz could be replaced by Chairman and Co-founder Scott McNealy after deal negotiations with International Business Machines Corp fell through.

“As a policy Sun does not comment on rumors or speculation. What we can say is that Sun is committed to its leadership team, growth strategy and building value for its shareholders,” the company said in a e-mailed statement.

Sun shares tumbled 25 percent on Monday. It rejected a $7 billion buyout bid from IBM, according to a person with knowledge of the matter, leaving the smaller server and software maker vulnerable to lawsuits from shareholders nervous about its viability as a stand-alone company.
