APPENDIX “II” — UNDERHAUL/OVERHAUL SAMPLE CALCULATION

Formula for Adjustment

When the average actual haul distance for a Contract Year is less than the Average Haul Distance, the BCM Rate for that Contract Year shall be adjusted as follows:

1/ distance adjustment = (actual average haul distance — Average Haul Distance)

2/ BCM Rate adjustment = (distance adjustment * Underhaul Rate)

3/ BCM Rate adjusted for distance = (BCM Rate + BCM Rate adjustment)

Likewise, when the average actual haul distance for a Contract Year is more than the Average Haul Distance, the BCM Rate shall be adjusted using the applicable Overhaul Rate and the same sequence of calculations.

The actual average haul distance shall be calculated using the shortest horizontal distances, measured centroid to centroid, along haulroads that could be used by the Contractor for Overburden Removal or muskeg/mineral soils removal, as the case may be, during that Contract Year.

Example:

The average actual haul distance for 2010 (Contract Year 6) is calculated to be [***] kilometres one way, using measurements based upon the shortest horizontal distance between centroids, along haulroads that could be used by the Contractor during that Contract Year.

•		The Average Haul Distance for 2010 set out in Rate Schedule “F” of Section “D” — COMPENSATION is [***] kilometres one way.
•		The BCM Rate for 2010 set out in Rate Schedule “E” of Section “D” - COMPENSATION is $[***] per bank cubic metre.
•		The Underhaul Rate for 2010 set out in Rate Schedule “G” of Section “D” — COMPENSATION is $[***] per bank cubic mete per kilometre.

	1)		distance adjustment = ([***] km — [***] km) = [***] km (rounded to two decimal places)
	2)		BCM Rate adjustment = ([***] km * $[***]/BCM-km) = $[***]/BCM (rounded to two decimal places)
	3)		BCM Rate adjusted for distance = ($[***]/BCM — $[***]/BCM) = $[***]/BCM (rounded to two decimal places)

Therefore, the BCM Rate for 2010, following adjustment for haul distance, would be $[***] per bank cubic metre. This rate would then be subject to escalation.

Contract Number: 400472		Page 39 of 41

APPENDIX “III” — ESCALATION FACTOR ADJUSTMENT, SAMPLE CALCULATION

Example: Adjustment to BCM Rates for Escalation or De-Escalation

BCM Rates shall be adjusted for escalation or de-escalation as follows:

BCe = BC * ([***] * WR + [***] * CPla)
                                                          CPlb

Where:

BCe = the BCM Rate adjusted for escalation or de-escalation;

BC = the BCM Rate for the period in question;

WR = the arithmetic average of the change, for the period in question, of the base wage rate at each of the Syncrude, Suncor and Albian open pit oil sand mines in the Fort ▇▇▇▇▇▇▇▇ area, relative to the base period of January to December, 2004 inclusive;

CPla = the arithmetic average of the January to December inclusive, first published indices for the Statistics Canada Consumer Price Index, Major Components, Selected Sub-groups and Special Aggregates (Not Seasonally Adjusted), Alberta, all items excluding energy, for the period in question; and

CPlb = the arithmetic average of the first published Indices for the Statistics Canada Consumer Price Index, Major Components, Selected Sub-groups and Special Aggregates (Not Seasonally Adjusted), Alberta, all items excluding energy, for the base period of January to December 2004 Inclusive;

Assume:

	(a)		The Contract Year in question is 2010 (Contract Year 6);
	(b)		The BCM Rate for 2010 set out in Rate Schedule “E” of Section “D” — COMPENSATION is $[***] per bank cubic metre;
	(c)		The BCM Rate for 2010 adjusted for haul distance is $[***]/BCM;
	(d)		By 2010 the change in base wage rate at the Syncrude open pit mine, relative to the base period of January to December 2004 inclusive, is [***]. Likewise the corresponding change at Suncor and Albian is [***] and [***] respectively;

APPENDIX “IV” — EXAMPLE OF DEPRECIATION COMPONENT OF REPLACEMENT EQUIPMENT
SAMPLE CALCULATION

Example: Determination of the depreciation component of Replacement Equipment charges for a particular year. The depreciation competent of Replacement Equipment charges for a particular year is determined by the following:

DCe = DC * (Pa/Pb) * (FXa/FXb)
where:

DCe = the depreciation component of Replacement Equipment Charges (REC) for a particular year of additions to Replacement Equipment adjusted for escalation or de-escalation;

DC = the depreciation Component of Replacement Equipment Charges for a particular year of additions to Replacement Equipment as set out in rate Schedules “Ct” to “Cix” inclusive:

Pa = the arithmetic average of the January to December inclusive, that published Indices for the US Department of Labor Producer Price index for construction machinery manufacturing,
Series ID: pcu333120333120, for the particular year of additions to R

Pb = the US Department of Labor producer Price Index for construction machinery manufacturing,
Series ID: pcu333120333120, for the base period which shall equal [***];

FXa = the weighted (by number of days in affect) average Canadian foreign exchange rate (US$CDN$) for the particular year of additions to Replacement Equipment; and

Fxb = the Canadian foreign exchange rate (US$/CDN$) for the base Period which shall equal [***]

Assume:
(a) The Contract Year in question is 2007 (Contract Year 3);

(b) For Contract Year 2:

responsible for obtaining all required permits and performing such Work in accordance with Regulations.

In order to ensure sufficient dyke building materials to meet Work Schedule requirements, the Contractor shall selectively mine the Overburden. The Contractor shall endeavor to achieve placement of seventy (70) percent of total Overburden Removal in ▇▇▇▇▇ (thirty (30) percent placement of total Overburden in waste dumps). Referring to Attachment “F” CNRL/Terracon Overburden Soil Classification and Material Utilization Chart (note that in the Mine the stratigraphic order of facies may differ from this chart) included in Section “E” – ATTACHMENTS, the following soil units shall be grouped together and mined as separate benches;

	•		Bench 1 — Ho, Hf, Hl, Pfs, Pfsa, Pfg/Pfsg, Pl (excluding muskeg and mineral soils when salvaged for reclamation purposes). The average thickness of this bench is approximately three and one-half (3.5) metres and typically this material can only be used for general fill for ▇▇▇▇▇ or placed in waste dumps. This bench may contain recoverable aggregate material which may have to be salvaged;
	•		Bench 2 – Pga, Pgtc, Pgts, Pgt, PgKc, PgKm (when total is greater than three (3) metres thick. When less than three (3) metres thick include with Bench 3 materials). Typically this till material will be suitable for constructing the dyke core and it must not be contaminated with deleterious materials as specified by the Owner. The average bench thickness is approximately four and one-half (4.5) metres;
	•		Bench 3 – Kc, Kcw. Typically this material is used for the “controlled Kc” zone of the dyke or for general fill;
	•		Bench 4 – Kc, Kcw (when required due to Overburden thickness);
	•		Bench 5 – Kc, Kcw (when required due to Overburden thickness); and
	•		Bench 6 – This bench is required when oil sands (Km) less than seven (7) percent bitumen by weight is greater than five (5) metres thick. When less than five (5) metres thick, include with the adjacent Kc, Kcw bench. When mined as a separate bench this lean oil sands material may be suitable for constructing the dyke core as well as for roads and other general fill purposes. Average bench thickness is approximately six and one-half (6.5) metres.

An illustration of bench material groupings and approximate thickness is provided in Attachment “I” Layout of Overburden Mining Benches and Thickness Histograms, included in Section “E”- ATTACHMENTS. The intent is to mine the complete thickness of each bench rather than to subdivide the bench to further segregate dyke building materials.

In the event during Overburden Removal the Contractor encounters any oil sands which may be greater than seven (7%) percent bitumen by weight, or any aggregate material, it shall notify the Owner. The Owner shall determine the quality of the material and if authorized by a Change Order from the Owner, the Contractor shall recover such oil sands or aggregate.

The Contractor shall remove Overburden down to the upper surface of the oil sands. The Owner will inspect the Overburden Removal area to identify the economic limit for the oil sands and will establish the position of the final ore contact. The Contractor shall leave the final ore contact clear of surface water, organic matter and Overburden, while minimizing losses of economic oil sands. The Contractor shall minimize the water flowing to the oil sands removal sites.

The separation distance required from the toe of Overburden Removal to the crest of oil sands removal shall be specified in the SWA.

The Contractor shall create the final pit wall slopes in accordance with Regulations and as specified in the SWA. Tension cracks in the final highwalls shall be sealed to minimize inflow of water.

The Contractor shall construct and maintain all haulroads it requires for Overburden Removal. Haulroads shall be constructed, maintained and operated in compliance with Regulations, and Attachment “B” CNRL Hauling Safety Procedures included in Section “E” – ATTACHMENTS. The Contractor shall provide a layout of its proposed haulroads to the Owner for approval prior to construction. Roadwork performed by the Contractor shall not disturb drainage systems (natural or otherwise). In the event that any drainage systems are disturbed, the Contractor shall restore them in accordance with Regulations, without cost to the Owner. At the Owner’s request the Contractor shall remove its haulroads constructed within the pit limits, including without limitation those it constructed on the oil sands, without cost to the Owner.

The corridor between the Southwest Pit and Waste Area 1, as illustrated in the Drawings, will be used in the future for tailings pipelines and then a dyke. The Contractor shall prepare the foundation for its roads or waste dumps in this corridor as follows:

	•		Muskeg and soft underlying materials will be removed;
	•		Stockpile organic materials suitable for reclamation at locations designated by the Owner; and
	•		Areas of ponded water on the prepared foundation surface shall be drained and/or filled with granular materials up to a level at least one-half (0.5) metres above the water level before non-granular materials can be place on this area.

The Contractor shall construct Dyke 10 in accordance with Attachment “D” Dyke 10 Muskeg Stripping Specification and Limits and Attachment “E” Dyke 10 Fill Construction Specifications both included in Section “E”- ATTACHMENTS. The Owner shall monitor the dyke building activities and the Contractor shall strictly comply with the Owner’s directions for such Work. Lift thickness shall be those required to achieve compactions specified for each zone of the dyke, as verified by the Owner’s field tests. In general, other ▇▇▇▇▇ will be built to similar specifications with the Owner providing further direction prior to construction of those structures.

The Contractor shall construct Waste Area 1 identified in the Drawings, with a one hundred (100) metre wide outer shell in accordance with the specifications for Zone 5 provided in Attachment “E” Dyke 10 Fill Construction Specifications, included in Section “E” – ATTACHMENTS. Furthermore, when constructing the ▇▇▇▇▇ ▇▇▇▇ ▇ outer shell, lift thickness shall not exceed five (5) metres and free-dumping shall not be allowed.

There are no specifications for compaction, fill surface preparation and clean-up requirements, or maximum lift thickness for the interior of Waste Area 1 or for waste dumps constructed within the mined out area of the Southwest Pit. This in no way relieves the Contractor from its responsibility to ensures safety of all persons and property as well as the environment when performing the Work.

The Contractor shall construct the tailings line corridor (TLC) identified in the Drawings in accordance with the specifications for Zone 2 provided in Attachment “E” Dyke 10 Fill Construction Specifications, included in Section “E” - ATTACHMENTS. Pipeline crossing sleeves for the TLC will be supplied by the Owner, and the number and locations of such crossings shall be mutually agreed by the Parties. A Change Order will be issued when the Contractor is requested to rebuild its haulroads at these crossings.

The Contractor shall ensure ponded water on dyke surfaces is removed prior to subsequent fill placement and shall control water run-off to such surfaces.

The Contractor shall coordinate its Work activities with Third Parties constructing the dyke filter and blanket drains and associated collection and outlet ditches, in order minimize disruptions to the Work or to the Third Party’s work.

The Contractor shall replace without cost to the Owner, any dyke monitoring instruments damaged by the Contractor.

The Owner shall require ongoing access to the ▇▇▇▇▇ and waste dumps and the Contractor shall coordinate its activities with the Owner’s in order to minimize disruption

Final surfaces of waste dumps and ▇▇▇▇▇ shall be contoured in preparation for placement of reclamation materials. Materials with a sodium adsorption ratio of twelve (12) or greater (generally Clearwater Formation material) are not to be placed within one (1) metre of these final surfaces. The Owner shall perform soil tests to identify areas of concern and when requested by the Owner, the Contractor shall place a lift up to one (1) metre thick of suitable Overburden on those areas.

The Contractor shall maintain all excavations, roads and other work areas free from dust, as determined by the Owner. The Owner shall first approve the method of dust control, before the Contractor implements the same.

Should the Owner require “flow-through ▇▇▇▇▇” to screen out course debris at the recycle water intake to the extraction plant, the Contractor shall construct such ▇▇▇▇▇ in accordance with the specifications for Zone 2 provided in Attachment “E” Dyke 10 Fill Construction Specifications included in Section “E” – ATTACHMENTS.

	2.3		Quality Control
			The Contractor shall notify the Owner when it reaches the top of oil sands and the Owner will inspect such area to identify the economic limit of the oil sands for the Contractor.
			When the Contractor has completed an Overburden Removal area it shall notify the Owner. The Owner shall inspect such area to determine if the Overburden/oil sands contact has been properly cleaned to the final ore contact and that such surface has been left clear of surface water, organic matter and Overburden and that water flowing to the oil sands removal sites has been minimized. If the area does not pass the inspection the Contractor shall correct all deficiencies until such time as the area can pass the inspection.
			When requested by the Owner to recover oil sands, the Contractor shall maximize recovery of the oil sands while minimizing dilution with Overburden. The oil sands/Overburden contact shall be cleaned to the satisfaction of the Owner prior to excavating the oil sands.
			When requested by the Owner to recover aggregate encountered in mining face, the Contractor shall maximize recovery of the aggregate while minimizing dilution with non-aggregate materials. The aggregate/Overburden contact shall be cleaned to the satisfaction of the Owner prior to excavating the aggregate.
