Allow cream cheese to soften. In a medium mixing bowl, beat cream cheese, granulated sugar, 1 egg and vanilla until thoroughly blended and smooth. Spread evenly in the bottom of prepared pie shell (if using frozen pie shell, thaw it first). Top with pecans.

In another bowl, beat 3 eggs, corn syrup and brown sugar until well blended. Pour evenly over pecans.

Cut four 2-inch long pieces of foil and arrange around the pie crust sides (this will help prevent pie crust from browning too much). Place in oven and bake at 425°F for 10 minutes. Reduce heat to 375°F and bake for additional 30 minutes, removing foil 15 minutes prior to end of baking time. Let cool.

Serve.
