Zusammenfassung:	A liner system has a setting collar at one end and is adapted for insertion into a well bore. The setting collar is adapted to couple with a liner running tool. A whipstock surface is provided on the setting collar and adapted to deflect a drilling string in drilling a lateral well bore off of the first well bore. A method of forming a well system includes forming a first well bore; installing a first liner in the first well bore, the first liner having a first whipstock surface adapted to deflect a drilling string; and then forming a second well bore extending from the first well bore by deflecting a drilling string through contact with the first whipstock surface.
