Preheat oven to 375�. Heat butter and olive oil in a saucepan over medium heat until butter is melted. Add garlic, pepper, Worcestershire sauce, basil, thyme and Tabasco. Cook and stir 1 to 2 minutes and remove from heat. Place shrimp in an 18x13x1 inch baking pan and pour butter mixture on top; toss to coat and arrange shrimp evenly in pan. Bake 8 minutes, then stir shrimp to coat with butter mixture again. Bake 6 to 8 minutes longer or until shrimp turn pink and are cooked through; do not overcook.
