UPDATE 2-First Calgary wins shareholder vote delay on CEO ouster

(Recasts with court judge's ruling, court proceedings)

CALGARY, Alberta, April 7 (Reuters) - First Calgary Petroleums (FCP.TO: Quote, Profile, Research, Stock Buzz) won a delay in a vote on a shareholder push to oust the company's chief executive after a judge ruled investors needed time to consider an 11th-hour show of support from Algeria's energy minister.

Dissident shareholders seeking to replace CEO Richard Anderson and elect a slate of directors for the company that is developing a large Algerian gas project will have to wait until April 18 for the vote, Alberta Justice Bruce McDonald ruled on Monday.

The meeting, the culmination of months of public sniping between 9.4 percent owner Waterford Finance and Investment Ltd and First Calgary, had been slated for Tuesday.

But the company, whose shares have been pressured by a failed sale process and delays in getting its only project developed, convinced McDonald that a letter it received Sunday from Algerian Energy and Mines Minister Chakib Khelil supporting its position was a material development that could sway the vote.

Shareholders' interests "will be prejudiced unless they have full and complete information," First Calgary lawyer Dan McDonald told the judge.

Khelil wrote he was "deeply concerned" about the proposal to replace Anderson and said that he would "look negatively" at changes to First Calgary's management.

"Any delays to the development of the project would be harmful to the Sonatrach-FCP relationship," he said.
