Major League Baseball President Robert A. DuPuy and Baltimore Orioles owner Peter G. Angelos met for several hours yesterday in an attempt to nail down a compensation package to offset the impact a Washington team will have on the Orioles. Both sides still have more work to do, according to sources familiar with the talks.

Angelos is seeking a financial package from baseball that will guarantee the value of the Orioles, as well as the state's investment in its Camden Yards baseball facility, in the event that a Washington team drains fans and money from the Baltimore franchise.

DuPuy and Angelos declined to comment.

The two sides have tentatively agreed on many of the details, including a 60-40 split of the revenue from a new Baltimore-Washington regional sports network, with the majority of revenue weighted toward Baltimore.

Negotiations are continuing on whether baseball will guarantee that the Orioles earn a minimum amount of annual revenue.

Another point is how long the guarantee will last. Angelos wants it in effect as long as a member of his family owns the Orioles.

Baseball is seeking an amicable settlement with Angelos, who long has opposed a team in the Washington area. The league announced last week over Angelos's objections that it will move the Montreal Expos to Washington.

Angelos and DuPuy are expected to resume negotiations later this week.
