G CO R GIS Data Resources, Inc. Police or Fire or EMS Boundaries Maximum 1. A complete rebuild of a response polygon Layer is considered part of a Release as long as it Limits does not occur more often than once every 2 years. If Customer has the need to completely rebuild polygon boundaries more often than once every 2 years, this may be subsequently incorporated in the Specifications at an additional cost 2. Geometry changes to 40% or less of the records in a response boundary file Spatial Accuracy 1. Any boundary work will be digitized and/or corrected to the street centerlines and other relevant features with respect to the most recent aerial imagery that GDR can obtain. If roads are so new that they do not appear on any imagery, GDR will then align boundaries using reasonable commercial efforts with the understanding that the Layer will be corrected to spatially accurate centerlines and imagery in a subsequent Release when said imagery becomes available to GDR 2. Any original boundary work found later to be in error in the original base map, will be corrected without counting against the Maximum Limit 3. All polygon boundaries that are to be coincident with the street centerline (i.e. exactly divide the street into a left and right half) will be completely coincident with the centerline where specified by Customer Attribution In the event of a complete rebuild of polygon boundaries, there is no limit to the number of polygon records permissible for Update Municipal and ZIP Code Boundaries Maximum Limit Geometry changes to 35% or less of the records in a municipal/ZIP boundary file Spatial 1. Any boundary work will be digitized and/or corrected to the street centerlines and other relevant Accuracy features with respect to the most recent aerial imagery that GDR can obtain. If roads are so new that they do not appear on any imagery, GDR will then align boundaries using reasonable commercial efforts with the understanding that the Layer will be corrected to spatially accurate centerlines and imagery in a subsequent Release when said imagery becomes available to GDR 2.

All polygon boundaries that are to be coincident with the street centerline (i.e. exactly divide the street into a left and right half) will be completely coincident with the centerline where specified by Customer Attribution There is no limit to the number of records in which Customer can modify attributes Auxiliary Linear Features (Hydrology, Rails, etc.) Maximum Limit Geometry changes to 30% or less of the total linear feet in an auxiliary line Layer file Spatial 1. Any line work will be digitized and/or corrected to the most recent aerial imagery that GDR can Accuracy obtain 2. Any original line work found later to be in error in the original base map, will be corrected without counting against the Maximum Limit Attribution There is no limit to the number of records in which Customer can modify attributes 8 Digital Drive, Suite 200, Novato, CA 94949 • (888) 654-4GDR (4437) • Phone (415) 884-4437 • FAX (415) 884-4407 Rev: 20051006 Page 10 of 12
