MULTI-POINT SURFACE USE & OPERATIONS PLAN

1. Existing Roads:

Directions to the proposed location are attached.

Refer to Topo Maps A and B for location of access roads within a 2-mile radius.

All existing roads will be maintained and kept in good repair during all drilling and completionoperations associated with this well.

2. Planned Access Roads:

The access road will be crowned (2 to 3%), ditched and constructed with a running surface of 18 feetand a maximum disturbed width of 30 feet. Graveling or capping the roadbed will be performed asnecessary to provide a well constructed, safe road. Prior to construction or upgrading, the proposedroad shall be cleared of any snow and allowed to dry completely.

Surfacedisturbance and vehicular traffic will be limited to the proposed location and proposed accessroute. Any additional area needed will be approved in advance. All construction shall be inconformance with the standards outlined in the BLM and Forest Service publication: SurfaceOperating Standards for Oil and Gas Exploration and Development. 1989.

The road surface and shoulders will be kept in a safe an usable condition and will be maintained inaccordance with theoriginal construction standards. All drainage ditches will be kept clear and free-flowing and will be maintained according to original construction standards. The access road surfacewill be kept free of trash during operations. All traffic will be confined to the approved disturbedsurface. Road drainage crossings shall be designed so they willnot cause siltation or accumulation ofdebris in the drainage crossing or shall the drainagesbe blocked by the road bed. Erosion of drainageditches by runoff water shall be prevented by diverting water off at frequent intervals by means ofcutouts. Should mud holes develop, they shall be filled in and detours around them avoided. Whensnow is removed from the road during the winter months, the snow shall be pushed outside of theborrow ditches, and the turnouts kept clear so that snowmelt will be channeled away from the road.

10. Plans for Reclamation of the Surface:

Producing Location:

Immediatelyupon well completion, the location and surrounding area will be cleared of allunused tubing, materials, trash, and debris not required for production.

Immediately upon well completion, any hydrocarbons in the pit shall be removed in accordancewith 43 CFR 3162.7-1.

Before any dirt work associated with location restoration takes place, the reserve pit shallbe as dry as possible. All debris in it will be removed. Other waste and spoil materials

will be disposed of immediately upon completion of operations.

The reserve pit and that portion of the location not needed for production facilities/operationswill be recontoured to the approximate natural contours. The reserve pit will be reclaimedwithin 90 days from the date of well completion, weather permitting.

To prevent surface water (s) from standing (ponding) on the reclaimed reserve pit area, finalreclamation of the reserve pit will consist of "mounding" the surface three feet above surroundingground surface to allow the reclaimed pit area to drain effectively.

Upon completion of backfilling, leveling, and recontouring, the stockpiled topsoil will be spreadevenly over the reclaimed area(s).

Dry Hole/Abandoned Location:

Abandoned well sites, roads, and other disturbed areas will be restored as near as practical totheir original condition. Where applicable, these conditions include the re-establishment ofirrigation systems, the re-establishment of appropriate soi1 conditions, and re-establishment

of vegetation as specified.
