For a base, the model uses 2' topographic contours for the Cerise Mine site along with USGS topography for the areas around the site. The model then pulls in the proposed topographic features (mining cells as well as overburden and topsoil stockpiles/berms) of the Cerise Mine per the proposed mining and reclamation plans. Some of the existing trees on land around the site and in the Wooden Deer Subdivision area were built into the model; all of the existing trees aren't included simply because of the amount of time that would be required to do so. The process to insert trees involves horizontally locating them based on information pulled from Google Earth aerial mapping and then placing a representative three dimensional tree in that location. Using the model, we have the ability to navigate to individual neighbors' properties or to public streets to look at the Cerise Mine in its various phases to get a realistic view of what will be seen. Based on the results of the model, as expected, due to the change in elevation, the entire mining operation is not completely screened from view; however, the proposed buffering and screening associated with the project is effective. What follows are representative screen shots from the model taken from five different vantage points around the mine site. Each screen shot shows what would be seen from an eye level of 5'8" above the existing surface of the ground. From each vantage point we have a screen shot showing what will be seen during Phases 1, 3, and 4B of the mine as well as a view of the site when it is reclaimed. In addition, we have included a map to show the location of each vantage point. We will have the computerized version of the model available for use in meetings and if any interested party would like us to provide a screen shot from another specific vantage point, we can provide that as well.

August 12, 2010 Mr. Corey Hansen Lafarge North America, Inc. — Western U.S. Region 10170 Church Ranch Way, Suite #200 Westminster, CO 80021 Re: Revised Augmentation Water and Cost Estimate for Cerise Ranch Pit Dear Corey: Per your request, we revised our original evaluation of the estimated consumptive use for mining at the proposed Cerise Ranch Pit and the associated costs for augmentation water, dated November 15, 2008. The revised analysis increases the estimated aggregate and concrete production at the site to 500,000 tons and 100,000 cubic yards, respectively. It also reduces the anticipated exposed surface area to zero acres, indicating that no groundwater will be exposed at the site. The remaining estimates regarding dust control, truck washing, and domestic use are considered accurate and were not changed. 1. Mining Assumptions & Operational Consumptive Uses Based on these assumptions, Lafarge's mining operations will require approximately 40.5 acre- feet of augmentation water. Augmentation water will be required year round, except for May 1499 West 120th Avenue, Suite 200 _ Denver, Colorado 80234-2759 (303) 452-6611 • Fax (303) 452-2759 www.applegategroup.com Assumption Annual Water Use Requirement Aggregate Production 500,000 tons 14.7 acre-feet Concrete Production 100,000 CY 15.3 acre-feet Dust Control 400,000 gallons/month (for8 months) 9.8 acre-feet Truck Washing 20,000 gallons/month (for8 months) 0.5 acre-feet Domestic 5,000 gallons/month 0.2 acre-feet Exposed Surface Area 0 acres 0 acre-feet Total - 40.5 acre-feet Based on these assumptions, Lafarge's mining operations will require approximately 40.5 acre- feet of augmentation water.

The timing of estimated mining consumptive use is: • Summer estimated mining consumptive use (July through September): 13.3 acre-feet • Winter estimated mining consumptive use (October through April): 18.4 acre-feet 2. Augmentation Water & Costs We understand the owners of the Cerise Ranch own 5.85 cfs of the Basin Ditch, which could be used for summer augmentation. The Basalt Water Conservancy District (Basalt WCD) also provides leases of augmentation throughout the year. Currently, the Basalt WCD leases water for industrial purposes at a rate of $220 per acre-foot per year with an initial $600 application fee. There are two options for Lafarge. 1) Use a combination of the ditch right and a lease, or 2) Use a lease year-round. The first option available to Lafarge for augmentation is a combination of a lease with the Basalt WCD and historic use credit from the Basin Ditch. We do not know the historic irrigation practices on the Cerise Ranch with the Basin Ditch. We completed an estimate of the historic consumptive use credit using only the State Engineer Office's (SEO) diversion records. From this estimate, we assumed the Basin Ditch could provide summer augmentation from May through September. We cannot determine the number of acres to dry -up for augmentation without more detailed infosutation. We assumed the lease rate to the Cerise Ranch for summer augmentation credit would be $150 per acre-foot a starting point for negotiations. This option will require further evaluation of the historic consumptive use. Lafarge will have to divert and return the portion of the Basin Ditch used for augmentation to the Roaring Fork River. The SEO is also likely to require installation of a measuring device to maintain records of diversions and returns of the Cerise Ranch's ownership in the Basin Ditch for augmentation. The second augmentation option available to Lafarge is to lease water from the Basalt WCD throughout the year. This option simplifies the future substitute water supply plan and reduces the need for measuring devices. The two options are summarized in the table below. The least expensive option would be Option 1, which is a combination of historic consumptive use credit from Basin Ditch and a lease with the Basalt WCD. However, this option will also Augmentation Plan Description Consumptive Use Credit Per AF: $150 Basalt WCD Lease Fees: Application: $600 Per AF: $220 Total Estimated Cost Option 1 Summer: consumptive use credits Winter: lease $1,990 $4,658 $6,648 Option 2 Summer: lease Winter: lease 0 $7,576 $7,576 The least expensive option would be Option 1, which is a combination of historic consumptive use credit from Basin Ditch and a lease with the Basalt WCD. However, this option will also Mr. Corey Hansen RE: Revised Augmentation Cost Estimate for Cerise Ranch August 12, 2010 Page 3 of 3 include more evaluation of the Basin Ditch and installation of a return structure and measuring device to be used during the operating life of the site. Option 2 provides a certain year round augmentation supply at a lease rate set by the Basalt WCD. Neglecting the initial application fee, it is more expensive by approximately $330 per year. A lease throughout the year simplifies the SWSP and also eliminates any Lafarge staff time to monitor and record the diversion and return of the Basin Ditch.

Lee Attorneys for the Basalt Water Conservancy District BASALT WATER CONSERVANCY DISTRICT WATER ALLOTMENT CONTRACT NO. 586 Pursuant to C.R.S. § 37-45-131 (2008) LAFARGE WEST, INC., a Delaware corporation (hereinafter "Applicant") has applied to the Basalt Water Conservancy District (hereinafter the "District") a political subdivision of the State of Colorado, organized pursuant to and existing by virtue of Section 37-45-101, Colorado Revised Statutes, et seq., for an allotment contract for beneficial use of water rights owned, leased, or hereafter acquired by the District ("Contract"). By execution of this Contract, Applicant agrees to the following terms and conditions and those certain terms and conditions set forth in the attached Order, which is fully incorporated as a part of this Contract: 1. QUANTITY: In consideration of the covenants and conditions herein contained, Applicant shall be entitled to receive and apply to beneficial use 0.189 cubic feet of water per second from the District's direct flow rights and 44.6 acre feet per year of storage or other augmentation water owned or controlled by the District. Applicant shall restrict actual diversions and consumptive use under this Contract to these amounts. The Contract amount is based on the water requirements table attached hereto as Exhibit B. Any increase or change in the water requirements to be served by the District will require an amendment to the subject Contract. 2. SOURCE OF ALLOTTED WATER: Water rights allotted pursuant to this Contract shall be from the District's water rights decreed to the Basalt Conduit, Landis Canal, Stockman's Ditch Extension, Troy and Edith Ditch, Robinson Ditch, or other water rights hereafter acquired by the District, including the District's right to receive storage water from Ruedi Reservoir and Green Mountain Reservoir. The District shall have the right to designate the water right or Decree of the District from which the Applicant's allotted rights shall be obtained. The Applicant's use of any of the District's water rights shall be subject to any and all terms and conditions imposed by the Water Court on the use of the District's said rights. Exchange or augmentation releases made from the District's storage rights in Ruedi or Green Mountain Reservoirs or other works and facilities of the District shall be delivered to the Applicant at the outlet works of said storage facility and release of water at such outlet works shall constitute full performance of the District's delivery obligation. Delivery of water from the District's storage rights in Ruedi or Green Mountain Reservoir shall be subject to the District's lease contract with the United States Bureau of Reclamation and any rules and regulations promulgated pursuant thereto. Releases from other facilities available to the District shall be subject to the contracts, laws, rules, and regulations governing releases therefrom. Furthermore, the District hereby expressly reserves the right to store water and to make exchange releases from structures that may be built or controlled by the District in the future, so long as the water service to the Applicant pursuant to this agreement is not impaired by said action. Allo„ Co nac 3. PURPOSE AND LOCATION OF USE: Applicant will use the water rights allotted pursuant to this Contract for beneficial purposes by diversion at Applicant's point of diversion under the District's direct flow water rights and/or for use by augmentation or exchange. Applicant will use the water allotted by the District within or through facilities or upon lands owned, operated, or served by Applicant, which lands are described on Exhibit A attached hereto; provided that the location and purpose of Applicant's use of said water shall be legally recognized and permitted by the applicable governmental authority having jurisdiction over the property served. Applicant's contemplated usage for the water allotted hereunder is for the following use or uses: Domestic/Municipal X Industrial Commercial Agricultural Other It is acknowledged that certain locations within the District may not be susceptible to service solely by the District's water rights allotted hereunder or the District's said water rights may not satisfy Applicant's needs and purposes. To the extent that service cannot be achieved by use of the District's allotted water rights, or in the event said service is inadequate, Applicant may utilize such other water rights, by way of supplementing the District's water rights, or otherwise, as is necessary to assure water service sufficiently reliable for Applicant's intended purpose or purposes. All lands, facilities and areas served by water rights allotted hereunder shall be situated within the boundaries of the District. Any quantity of the Applicant's allocation not delivered to or used by Applicant by the end of each water year shall revert to the water supplies of the District. Such reversion shall not entitle Applicant to any refund of payment made for such water. Water service provided by the District shall be limited to the amount of water available in priority at the original point of diversion of the District's applicable water right and neither the District, nor those entitled to utilize the District's decrees, may call on any greater amount at new or alternate points of diversion. The District shall request the Colorado State Engineer to estimate any conveyance losses between the original point and any alternate point and such estimate shall be deducted from this amount in each case. The District, or anyone using the District's decrees, may call on any additional sources of supply that may be available at an alternate point of diversion, but not at the original point of diversion, only as against water rights which are junior to the date of application for the alternate point of diversion. In the event the Applicant intends to institute any legal proceedings for the approval of an augmentation plan and/or any change to an alternate point of diversion of the District's water right to allow the Applicant to utilize the water allotted hereunder, the Applicant shall give the District written notice of such intent. In the event the Applicant develops and adjudicates an alternate point of diversion and/or an augmentation plan to utilize the water allotted hereunder, Applicant shall not be obligated to bear or defray any Allot Coo t rad No, 586 11-5., I ll,doc 2 legal or engineering expense of the District incurred by the District for the purpose of developing and adjudicating a plan of augmentation for the District. In any event, the District shall have the right to approve the Applicant's application for change of water right, and/or augmentation plan or other water supply plan involving the District's rights, and the Applicant shall provide the District copies of such application and of all pleadings and other papers filed with the Water Court in the adjudication thereof. The District reserves the exclusive right to review and approve any conditions which may be attached to judicial approval of Applicant's use of the District's water rights allotted hereunder. Applicant agrees to defray any out-of-pocket expenses incurred by the District in connection with the allotment of water rights hereunder, including, but not limited to, reimbursement of legal and engineering costs incurred in connection with any water rights adjudication necessary to allow Applicant's use of such allotted water rights; provided, however, in the event any such adjudication involves more of the District's water rights than are allotted pursuant to this Contract, Applicant shall bear only a pro rata portion of such expenses. Applicant shall be solely responsible for providing the structures, works and facilities, if any, necessary to utilize the District's water rights allotted hereunder for Applicant's beneficial use. 4. PAYMENT: Applicant shall pay annually for the water service described herein at a price to be fixed annually by the Board of Directors of the District for such service. Payment of the annual fee shall be made, in full, within fifteen (15) days after the date of a notice from the District that the payment is due. Said notice will advise the Applicant, among other things, of the water delivery year to which the payment shall apply and the price which is applicable to that year. If a payment is not made by the due date, a late fee of $50 (or such other amount as the Board may set from time to time) will be assessed and final written notice of the delinquent account and late fee assessment will be sent by the District to the Applicant at Applicant's address set forth below. If payment is not made within thirty (30) days after said final written notice, the District may, at its option, elect to terminate all of the Applicant's right, title, or interest under this Contract, in which event the water right allotted hereunder may be transferred, leased or otherwise disposed of by the District at the discretion of its Board of Directors. In the event water deliveries hereunder are made by or pursuant to agreement with some other person, corporation, quasi -municipal entity, or governmental entity, and in the event the Applicant fails to make payments as required hereunder, the District may, at its sole option and request, authorize said person or entity to curtail the Applicant's water service pursuant to this Contract, and in such event neither the District nor such persons or entity shall be liable for such curtailment. \itot Contract No. 5?1.1; 11-5-I0.ch' 5. APPROPRIATION OF FUNDS: The Applicant agrees that so long as this Contract is valid and in force, Applicant will budget and appropriate from such sources of revenues as may be legally available to the Applicant the funds necessary to make the annual payments in advance of water delivery pursuant to this Contract. The Applicant will hold harmless the District and any person or entity involved in the delivery of water pursuant to this Contract, for discontinuance in service due to the failure of Applicant to maintain the payments herein required on a current basis. 6. BENEFIT OF CONTRACT: The water right allotted hereunder shall be beneficially used for the purposes and in the manner specified herein and this Contract is for the exclusive benefit of the Applicant and shall not inure to the benefit of any successor, assign, or lessee of said Applicant without the prior written approval of the Board of Directors of the District. Upon the sale of the real property to which this Contract pertains, Applicant has a duty to make the buyer aware of this Contract and the need to assign the Contract to the buyer. However, prior written approval of the Board of Directors of the District is required before the assignment is effective. Payment of an assignment fee in an amount determined by the Board shall be required as a prerequisite to approval of the assignment.

Any and all conditions imposed upon the release and diversion of the water allotted hereunder in the decree of said Water Court shall be incorporated herein as a condition of approval of this Contract.

If all necessary Permits are not acquired by the end of the second Lease Year the Company may continue the Lease in effect for a third Lease Year and, if necessary, for a fourth Lease Year, by payment of the sum oall per Lease Year as rent (plus the Advance Minimum Royalty described in Paragraph 4.C.i, below) at least 30 days prior to the end of the applicable Lease Year for which the extension is sought, or the Company may instead terminate the Lease without obligation to make any further annual. payments. B. The signing bonus and any annual Mill payment to extend the Term of the Lease under Paragraph 4.A, above, if required Permits have not been obtained are considered non- refundable and are not considered as Advance Minimum Royalty. Additional annual payments under Paragraph 4.C.i shall be considered Advance Minimum Royalty. - 3 - C. Advance Minimum Royalties. i. Prior to obtaining Permits, if the Company extends the Lease for a third Lease Year and, if necessary a fourth Lease Year, in addition to the annual rental paid pursuant to Paragraph 4.A for those Lease years, the Company shall also pay, at the time of payment of the rental, an Advance Minimum Royalty of Ewa for the Lease Year. ii. In addition to any Advance Minimum Royalty paid pursuant to Paragraph 4.C.i, Advance Minimum Royalty shall be paid annually at the rate of, for each Lease Year, commencing the earlier of: a. The date all necessary Permits that allow the Company to begin production and sale of Materials have been obtained and prior to the commencement of production and sale of Materials from the Property, in which case the first Advance Minimum Royalty shall be prorated based on date Company obtains all necessary Permits, or b. The commencement of the fifth Lease Year if the Company has not terminated the Lease. iii. The Advance Minitnum Royalty shall be increased to the rate of aper Lease Year for each Lease Year: a. That begins after the commencement of production and sale of Materials from the Property, or b. Commencing the sixth Lease Year if production has not yet commenced and Company has not terminated the Lease. iii. Other than the payment made upon execution of this Lease and any annual payment pursuant to Paragraph 4.A, above, all amoral payments made to keep the Lease in effect shall be deemed Advance Minimum Royalty recoverable against Sales Royalty as provided below in this Paragraph; however no Advance Minimum Royalty shall be refundable once paid. iv. The emulative amount of Advance Minimum Royalty the Company is required to pay during the Term of this Lease shall in no event exceed the lesser of: a. al; or b. the equivalent of the Sales Royalty (using the Base Royalty rate) on -ice an of the mineable and permitted quantity of the Materials that the Company determines are economically recoverable and salable from the Property (after processing and allowing for rejection of tailings), based upon calculations in accordance with recognized industry standards and practices. If the base volume of feed tons changes from the time this Lease is executed to the time production of Materials begins due to Permit restrictions, recalculations, third party interests or similar changes in the existing mine plan, then the maximum cumulative amount of Advance Minimum Royalty the Company is required to pay during the Perm of the Lease shall be adjusted using the above formula and new base feed ton volume. v. The Advance Minimum Royalty payment for a Lease Year shall be due on or prior to commencement of that Lease Year. Amounts paid as Advance Minimum Royalty shall be credited as an advance payment of and applied to reduce Materials tonnages otherwise subject to the Sales Royalty pursuant to Paragraph 3.A, based upon the tonnage associated with the royalty rate in effect at the time the Sales Royalty is accrued. Sales Royalties paid pursuant to Paragraph 3.A, after taking into account Advance Minimum Royalties paid pursuant to this Paragraph, shall be applied in succeeding years to reduce amounts subsequently payable as Advance Minimum Royalty. Il' Import Fees become payable pursuant to Paragraph ID, the Company at its option may credit Advance Minimum Royalty not previously applied against the Import Fees otherwise due. Upon termination of this Lease for any reason, the obligation to make Advance Minimum Royalty payments shall likewise temlinate except as to payments that became due prior to termination. 5. Weighing of Materials; Commingling. For purposes of calculation of Sales Royalty and/or Import Fees, quantities of Materials removed from the Property on which a Sand and Gravel Fee (whether Sales Royalty or Import Fee) is due will be measured as follows: A. Use of Scales. All Materials shall be weighed on a certified scale upon sale and removal from the Company's Plant site. If Materials on which a Sand and Gravel Fee is due are mixed with non -excavated materials (for example, in case of mixing sand and gravel with water and Portland cement in the concrete batch Plant), then for the purpose of calculating the Sand and Gravel Fee, the weight of the Materials used in the mixture will be determined using the certified scales at the batch Plant that measure the weight of the materials that comprise the mixture and deducting the weight of the added non -excavated materials, if necessary. Subject to Paragraph 5.D, below, the weight of Imported Materials and Recycle Materials used in concrete or other mixed products sold from the Property shall be calculated in the same manner as newly excavated Materials. B. Scale Adjustments. Accuracy of the scale shall be checked and adjustments made at least as often as required to continue to be certified. Records of the accuracy check and adjustments shall be preserved and made available in the same manner as other records. C. Commingling. Subject to Paragraph 3.0, the Company may commingle Materials extracted tiom the Property with Materials extracted and removed from other properties. In order to fairly and properly allocate production between properties from which commingled Materials are extracted, the pit run Materials extracted from each property shall be weighed prior to cormningling on certified conveyor belts scales upon removal from the relevant property. Records will be kept as to the tonnages removed from each property, and the total production for each calendar month will be attributed to each property pro -rata, after adjustment of the total tonnage of pit run from all properties for washed fines and tailings pursuant to Paragraph 5.F. below. Materials -5- from one property added to a stockpile at any time during a calendar month shall be deemed added simultaneously and pro rata with Materials from any other Property. The quantity of Materials detennined to be in the stockpile as of the commencement of any calendar month shall be deemed sold and removed, on a first -in first -out basis, prior to the sale of any Materials added to the stockpile during a subsequent calendar month The Company's measurement and determination shall be initially conclusive, but subject to audit by Lessor. 1). Accounting; Records. Recycle or Waste Material shall be weighed upon delivery or return to the Property, with the quantity and type of material being recorded. Products containing reprocessed Recycle Material or Waste Material shall be weighed upon leaving the Property in the same manner as other products containing sand and gravel aggregate. As the Recycle Material is used by the Company, records shall be kept of quantities in order to permit Lessor to verify the amount of Recycle Material brought onto the Property, used for asphalt or concrete production, and removed from the Property as new production or otherwise. Recycle Material and Waste Material may be commingled in a single stockpile with new Materials only after being weighed and properly accounted for. Withdrawals from any such stockpile for production of new asphaltic or concrete products shall be deemed to be on a "first -in first -out" basis for determining when payment of any Import Fee or other Sand and Gravel Fee for Materials included in the commingled stockpile becomes payable. E. Ownership. Recycle Material and Waste Material shall be the property of the Company. As deemed necessary by the Company, the Company shall bring in crushing equipment to crush the Recycle Material or Waste Material. F. Allowance for Tailinns. Tonnage for purposes of calculation of Sales Royalty shall be based on processed Materials sold. If Materials are not being commingled from separate properties, then the tonnage sold shall be calculated pursuant to Paragraph S.A. above. If due to commingling, Materials are weighed as pit run before processing and sale by the Company pursuant to Paragraph 5.A, above, the weight of tailings and washed fines shall be deducted from the total pit run weight of the Materials attributed to each property for purposes of calculating Sales Royalties. Both parties agree that as much as approximately fifteen percent (15%) of the minable in situ (in place, in the ground) sand and gravel onsite may need to be rejected as washed fines or tailings or otherwise in order to meet commercial specifications for salable Material. If rejected mined Materials exceed twenty five percent (25%) of total tonnage mined, the Company shall pay Sales Royalty on the percentage of tonnage of rejected Materials that exceeds fifteen percent (15%) of total tonnage of Materials mined. Materials that are deemed non -economic to mine shall not be included in the foregoing calculation, which pertains only to Materials mined, processed and rejected. 6. Water. During the Term of this Lease, and until reclamation of the Property is completed, Lessor shall make available the water and water rights yielding, on average, at least 29.3 acre feet per year listed in the November 18, 2008 report of Applegate Group, Inc., attached hereto as Exhibit B. If the total available yield of the Exhibit B water rights is reduced due to senior calls or physical availability, the 29.3 acre feet shall be proportionally reduced. If in any year, such water rights do not yield at least 29.3 acre feet due to senior calls or physical unavailability, or if, for any other reason, additional water or water rights are required, the Company shall provide at its sole cost and - 6 - expense such additional water required to satisfy the requirements of state law including, without limitation, the requirements of CRS 37-90-137(11). The Company shall be responsible for obtaining a temporary substitute supply plan or augmentation plan for use of such water, which shall make adequate provision for evaporative losses, wash plant operations, dust control and any other uses of water as part of the mining operation. The Company will not expose groundwater as part of the mining operation or final reclamation plan, and, conditioned upon the Company's compliance with its obligation not to expose groundwater, shall not be required to apply for a permanent augmentation planto cover any evaporative losses resulting from mining operation after termination of operations under the Lease. The Advance Minimum and Sales Royalties payable hereunder take into account the value of the water and water rights of Lessor to be used hereunder, and such water and water rights shall be supplied by Lessor at no additional cost to the Company. All water rights of Lessor used by Lessee pursuant to this Paragraph shall revert. to Lessor upon termination of this Lease for any reason.

The Basalt Water Conservancy District (Basalt WCD) also provides leases of augmentation throughout the year. The Basalt WCD leases water for $202 per acre-foot with a $600 application fee. There are two options for Lafarge:, 1) Use a combination Of the ditch rightand a lease, or 2) Use a lease year-round The frost option available to Lafargefor augmentation is a Combination of a,lease'with the Basalt WCD and historic use credit from the Basin Ditch:; We do not know the historicirrigation practices on the Cerise. Ranch with the Basin Ditch. We Completed an estimate of the historic 'consumptive use credit using only the State•Bngineer Offices (SEO) diversion records. From this estimate, we' assumed the Basin Ditch could provide .stammer 'augmentation fiam.May through .September. We .cannotdetermine the numberof acres to dry -up for augmentation without more detailed information, We assumed the lease rate to. the Cerise Ranch for summer,: augrnentation credit would'. be $150 per acre foot a starting ,point for negotiations. This option will require fur'tlrer• evaluation of the historic consumptive use. Lafarge will lutve to divert and return the portion of the Basin Ditch used for augmentation to the.Roaring•Eoik River. The SEO is also likely to require installation of a measw'ing device to maintain records .of diversions and returns of the Cerise Ranch's ownership in. the•Easin Ditohfor augmentation. The second auginentation.option available to Lafarge is to lease water from the Basalt WCD throughout the year, This option simplifies the future substitute water supply plan and reduces. e need for measuring devices. ,The two options are summarized in the table below T ze. least expensive option would be Option 1, which is a combination:of historic' consumptive .. use credit front Basin Ditch arid a teasewith the.

Boundaries of permit area to be generally as follows: • North boundary to be located approximately 50 feet south of the Basin Ditch. Mining should stop approximately 200 feet south of the Basin Ditch. • East boundary to be located approximately 25 feet west of the east property line. • South boundary to be located approximately 30 feet north of south property line. • West boundary to be located approximately 100 feet east of Crystal Springs Creek. Exception to this would he the area would be anticipated for entrance in to the mine off of County Road 103. This entrance is anticipated to be located in an area of about 800' from the north boundary to the south along this west boundary line. Phasing of Production Gravel mining and production to generally coincide with the following phasing plan.: • Phase One — To include initial opening of the pit and establishment of entrance. This phase is approximately 15 to 20 acres in size. Initial stripping will happen in the northerly half of the phase (IA). As production is need, the southern half of this phase (113) shall he stripped and readiedfor production The area is generally parallel to Crystal Springs Road to the east and a width of approximately 400 to 700 feet in width. Permanent entrance to pit shall be located off of Crystal Springs Road into this initial phase on the northerly end of this phase. A 48" high agricultural fence as approved by Lessor shall generally consist of 4 lines of taunt heavy duty barb wire, adequate number of wood and steel line posts, wood corner and line bracing, and intermediate wood stays. This fence shall be installed at boundary of each phase to keep livestock from entering pit and leaving property. Irrigation tail water shall be considered and allowed to flow thru the pit area if necessary. Top soil stripping from this phase shall be used to provide landscape berms on the north side of the Basin Ditch for visual and noise suppression. • Phase Two -To include area on south central side of permit area. This phase is approximately 10 to 12 acres in size. All fencing and tail water situations as described in Phase One shall be considered. • Phase Three -To include area in south east comer of permit area. This phase is approximately 10 to 12 acres in size. All fencing and tail water situations as described in phase one shall be considered. • Phase Four- To include area in north central side of permit area. This phase is approximately 10 to 12 acres in size. All fencing and tail water situations as described in phase one shall be considered. Phase Four could come before Phase Three if necessary. • Phase Five- To include area in north east corner of permit area. This phase is approximately 14 to 16 acres in size. All fencing and tail water situations as described in phase one shall be considered. Mining and Restoration of project. Striping and stock piling of overburden It generally should be assumed that stripping of subsequent phases will happen when most of previous phase is mined_ Striping from subsequent phases will be used to start restoration of previous phases when possible. Overburden piles will be properly sloped and re -vegetated with grasses to avoid dust and erosion. No roads will be allowed in any phase prior to start of stripping of that phase. See Conceptual Phasing and Reclamation Plan for berming and stock piling considerations. Reclamation considerations All existing top soil (12" to 18") will be separately stripped and stored for final cover of site. All other overburden shall be separately stored for reshaping of mined areas. All areas that are reclaimed shall be re -vegetated with grasses and trees. All reclaimed areas shall be provided with proper methods of delivery and coverage of irrigation water (ie: sprinkler irrigation via a wheel roll sprinkler system or similar). Service roads should be provided to access the perimeter of the site as well as access into the floor from the existing main ranch area. Intent of Final product At the end of the mining process, there shall remain undisturbed soil for up to 10 house pads for future development. These pads shall be located in the upper benches of the mined area. A majority of these pads will be located on the North side of the permit area, south of the Basin Ditch. The location of these pads in each phase will occur prior to the starting of that phase. A lake in the bottom of the floor may be mined for future development (bottom of lake at no time shall penetrate existing ground water conditions). EXHIBIT D PERMITTED EXCEPTIONS 1.

The environmental solutions company November 16, 2010 Mr. Sean Frisch Lafarge North America, Inc. — Western U.S. Region 10170 Church Ranch Way Suite 200 Westminster, CO 80021 Re: Water Quality Assessment for Cerise Property Dear Sean: This letter provides a summary of the analytical results of groundwater samples collected from wells TW -1 and TW -2 at Lafarge West, Inc.'s proposed Cerise Mine near Carbondale, Colorado. The objective of the sampling was to conduct an initial assessment of the suitability of groundwater from TW -1 and TW -2 as a source water for mine operations and facilities, in accordance with Garfield County Unified Land Use standards. Procedures Two groundwater samples were collected from wells TW -1 and TW -2 on November 2, 2010 for chemical analysis. Prior to groundwater sampling, these wells were developed by purging in excess of ten wet - casing volumes using a small diameter submersible pump. Immediately following development, groundwater samples were collected and placed into clean, laboratory -supplied containers, labeled, logged onto chain of custody documents, and placed on ice in coolers for transport to Colorado Analytical Laboratories, Inc. in Brighton, Colorado for analysis (some special parameter analyses were subcontracted out to other labs). In accordance with Garfield County requirements, the samples were analyzed for basic inorganic and other parameters for which there are Colorado Primary Drinking Standards, including metals, anions, general chemistry, bacteria, asbestos, and radionuclides. As recommended by Garfield County, parameters for which there are Secondary Drinking Standards (effecting taste, odor, color, staining, scaling etc.) were also analyzed. To assess the suitability of the groundwater for the intended uses, the analytical results were compared the Colorado Department of Public Health and Environment (CDPHE) Standards established in the Colorado Primary Drinking Water Regulations, 5 CCR 1003-1, Amended August 9, 2010, Effective November 30, 2010. In this regulation, an individual standard is either categorized as a Maximum Contaminant Level (MCL) or Secondary Maximum Contaminant Level (Secondary MCL). An MCL means the maximum permissible level of a chemical parameter in water, as delivered to any user of a public water supply system. Parameters with Secondary MCLs primarily affect the aesthetic qualities relating to the public acceptance of domestic water. Secondary MCLs are not enforceable, but are intended as guidelines. 3581 Stagecoach Road, Suite 205 • Longmont, Colorado 80504 • 720-494-2600 • Fax 720-494-2688 www.envirogroup. corn Sean Frisch November 16, 2010 Page 2 Results and Discussion Included in Attachment A of this letter is a table summarizing the analytical results for the collected groundwater samples (TW -1 and TW -2). Well development and field water quality sampling forms are provided in Attachment B. Attachment C contains a copy of the laboratory reports. The results indicate that groundwaters from wells TW -1 and TW -2 are suitable for use as a supply of water for personnel facilities and mining operations. Total coliforms were reportedly present in the sample from TW -2. However, prior to sampling, the wells were not subjected to routine disinfection practices that would be performed prior to putting a well into service for drinking water purposes. Any coliforms present in the wells would be effectively treated using standard procedures and a disinfection agent. No other exceedances of the CDPHE Standards with respect to the Primary MCLs were identified. Four parameters were identified to exceed the Secondary MCLs in one or both samples, including aluminum, iron, manganese, and total dissolved solids. Additional well development may alleviate some of those issues. If needed, implementation of simple water treatment system could improve the aesthetic quality of the water for drinking and other domestic uses. Assuming that the source of elevated aluminum, iron, manganese, and total dissolved solids in the water samples is from particulate matters, applying a simple filter system to the water could reduce concentrations of those parameters to be below the Secondary MCLs.

A portion of each filter was collapsed with acetone and etched in a plasma asher. The etched filter was then coated with a thin layer of carbon in a carbon side down. The sample was then placed inside a condensation washer and treated with acetone to remove the filter matrix and expose any inert material. For each sample, enough grid openings on a 200 mesh TEM grid are analyzed to ensure an analytical sensitivity of at least 0.005 structures/cc. A minimum of four grid openings from two preparations are analyzed for each sample. The grid openings are searched for fibrous structures which, if present are analyzed by SAED and/or EDX (elemental analysis). The AHERA protocol requires SAED confirmation of enough chrysotile asbestos structures on each sample to cause the sample to exceed 70 structures/mm2 (usually 4 or 5 structures). Both SAED and EDX confirmation are required of enough amphibole structures on each sample to cause the sample to exceed 70 structures/mm2 (usually 4 or 5 structures) per sample. Either SAED or EDX is required for the remaining asbestos structures of either type. The morphology of each structure is determined and the length and the diameter of any asbestos structures are recorded. Asbestos fibers, bundles, cluster and matrices were identified and recorded. The asbestos structures have been defined in AHERA as follows: Fiber: is a structure having a minimum length greater than or equal to 0.5 micron with an aspect ratio of 5:1 or greater with substantially parallel sides. Bundle: is a structure composed of three or more fibers in parallel arrangement, with each fiber closer than the diameter of one fiber. Cluster: is a structure with fibers in random arrangements such that all fibers are intermixed and no single fiber is isolated from the group. Matrix: is a fiber or fibers with one end free and the other end embedded or hidden by a particulate. The exposed fiber end must meet the fiber definition given above. If more than 50 asbestos structures are identified and confirmed on a sample, AHERA analysis may be terminated after completion of the grid opening, which contains the se structure. AHERA protocol requires the laboratory to reject any clearance sample which contains in excess of 25% total particulate loading or which appears to be unevenly loaded. The AHERA protocol includes specific sampling requirements, including minimum numbers of samples and minimum air volumes. Specifically, the 70 structures/mm2 clearance criteria is only allowed for sets five inside samples (collected in a group of 13 samples including: five outsides and three blanks) with volumes greater than 1200 liters (40 CFR Part 763, page 41894). Deviation from the AHERA sampling protocol may affect the validity of the analytical results.

The tests were completed on November 11 and 12, 2010. The following provides information on the background and well construction, testing procedures, results, and discussion. Background The two test wells, referred to as TW -1 and TW -2 (Figure 1), were installed in October 2010 by EnviroGroup Limited and Layne Christensen Company. Borehole geologic logs and well construction details for TW -1 and TW -2 are provided as Attachment A to this letter. Both wells were completed to a depth of approximately 150 feet below ground surface (bgs). The borehole for TW -1 was drilled to 170 bgs without encountering bedrock. Current static depths to water below ground surface are approximately 102.5 feet and 99 feet for TW -1 and TW -2, respectively. The aquifer screened by both wells consists of gravel and sand with cobbles and traces of silt and clay. Lafarge anticipates the need for approximately 40.3 acre-feet of water per year for mining and processing operations, and 0.2 acre-feet per year for domestic uses (total average of approximately 25 gpm on a continuous basis). Testinz Procedures Both wells were equipped with temporary one -horsepower pumps and totalizing flow meters for the tests. The pumps were powered by portable generators, and polyethylene discharge lines for each well were extended to Crystal Creek. Discharges during the tests were authorized under and performed in compliance with a permit obtained by Lafarge under Colorado Discharge Permit System Regulations (General Permit for Subterranean Dewatering). Water levels in the pumping wells were monitored through the use of continuously recording pressure transducers and an electronic data logger. The tests were observed by EnviroGroup personnel throughout their durations. Manual measurements were also recorded for water level verification, and flow rates were recorded periodically throughout the tests. Both tests were conducted near the maximum capacity of the test pumps and the discharge rates remained essentially constant throughout both tests. Because of the distance between the wells and small area of 3561 Stagecoach Road, Suite 205 • Longmont, Colorado 80504 • 720-494-2600 • Fax 720-494-2698 www. envi rog roup. corn Sean Frisch November 17, 2010 Page 2 influence of pumping at each well, the tests could be run simultaneously, with the TW -1 test initiated approximately 40 minutes after starting the TW -2 test. Water levels in other site piezometers screened in the same aquifer (PZ -1, PZ -2, and PZ -3 — see Figure 1) were also manually measured periodically during and for several hours after the 24-hour pumping tests. Test Results Graphs of the drawdown data for TW -1 and TW -2 are provided in Attachment B. The constant pumping rates for TW -1 and TW -2 were approximately 24.3 gallons per minute (gpm) and 27.2 gpm, respectively. The maximum drawdowns were approximately 0.87 feet for TW -1 and 1.9 feet for TW -2. The majority of these drawdowns were achieved within the first hour of the tests. Recovery of water levels in TW -1 was monitored for one hour (the check valve at TW -2 did not hold resulting in water in the drop pipe flushing back into the well and affecting recovery levels). Monitoring of PZ -1, PZ -2 and PZ -3 indicated no significant or readily discernable effect from the pumping at TW -1 and TW -2. Due the highly transmissive nature of the aquifer, the radius of influence on water levels due to pumping the required volumes would be small. The pumping test results prove the aquifer to be prolific and capable of producing sustained discharge rates substantially higher than the testing rates, if needed, without significantly increasing drawdown. As expected, the aquifer appears to be capable of producing slightly higher volumes of water the closer a well is to the south side of the property and the Roaring Fork River. Discussion The pumping tests show that the aquifer and the test wells can provide an ample supply of water to support a mining operation at the Cerise property. TW -2, or similar well, would provide a more than adequate supply of water for the office and personnel facilities. The productivity of the test wells is more limited by the size of pump that can be installed in this size well. The existing wells have suitable capacity to support or fulfill the water needs of the proposed project. Based on the estimated water demands, the productivity of the existing wells or new wells would not be a limiting factor in obtaining well permits to satisfy the project needs. Additional and/or larger diameter well(s) would provide additional backup capacity for mining and processing activities in the case of mechanical upsets.

This analysis is for the Lafarge Cerise Mine Property. The proposed mine is located in the southeast t/a of Section 26 and the southwest 1/4 of Section 25, Township 7 South, Range 88 West of the 6th Principal Meridian. The site is outside of Carbondale, Colorado in Garfield County. Several aggregate mines are present in the area. Other land uses in the area are predominately agricultural and rural residential. Several structures including power poles, irrigation ditches, fences, a gas line and meter, a telephone line, a private bridge, and state and county highways are within 200 feet of the mine limits of the proposed mine area. The locations of the structures are shown on Figure 1. Regional geologic mapping (see below) indicates mining will be in terrace and pediment alluvial deposits. GEOLOGIC STRATA AND MINING CONDITIONS Geologic mapping by Ellis and Freeman (1984) indicates the proposed mine site is north of the Roaring Fork River on an undifferentiated terrace and pediment alluvial deposit Holocene to Pleistocene in age (1.8 mya to present). The deposit is composed of various amounts of cobbles, gravels, sands, silts, and clays. The site subsurface conditions were investigated through an exploratory drilling program conducted by others. The results of exploratory borings drilled in 2007 indicate that bedrock was not encountered to the maximum depth explored (119') within the proposed mine limit. Mining in the proposed mine limits will result in maximum highwalls approximately 100 feet high. Mine highwall configurations will vary depending on the location within the mine, and will have either a 3:1 (horizontal (H):vertical(V)) slope or have a benched configuration. Locations of the highwall configurations can be found on Figure 2. Groundwater was not encountered in the borings, was not observed in onsite piezometers, and is not anticipated to impact mining operations. Groundwater was modeled at a depth of 90 feet below the ground surface to represent a conservative scenario. From a geotechnical standpoint, the sand and gravel will form most of the mine slope. These soils are generally strong and stable, particularly when no groundwater is present. Minor amounts of clay will lie at the ground surface and locally as lenses within the sand and gravel. 1900 S. Sunset Street, Suite 1-F Longmont. CO 8050! Tel 303.772.5282 Fax 303.772.7039 www.tetratech.com TETRA TECH KNOWN STRUCTURES WITHIN 200 FEET OF MINING LIMITS Known man-made structures within 200 feet of the mine limits are listed below: • Colorado State Highway 82 • Garfield County Road 103 (Crystal Springs Road) • A buried telephone line • A buried 10" gas flow line and associated gas meter • An overhead electric service and associated power poles • The Basin Ditch ▪ A private bridge spanning the Basin Ditch • An 18" diameter ilTigation pipe • Various fences surrounding the property. STABILITY ANALYSES Mr. Sean Frisch July 19, 2010 Page 2 Stability analyses were performed in order to evaluate potential for damage to existing permanent structures due to mine highwall slope failures. Analyses were performed with the Slope/W 2007 v7.I6 computer program. For each case we analyzed the most critical soil profile(s) based on exploratory boring data (i.e. the tallest highwall, thickest overburden layer, etc). The stability analyses were run in accordance with accepted geotechnical standards and DRMS requirements for temporary pit slopes. The conditions modeled are summarized as follows: • Two mine highwall scenarios were modeled based on the mining plan o A 3:1 (H:V) mined highwall o A 25' high interslope bench configuration with I:1 slopes and 20' wide catch basin. benches • Factor of Safety must be greater than 1.0 Groundwater levels on the profiles were input to portray conservative site conditions at an elevation of 90 feet below grade. Laboratory strength tests were not performed on soils from the site. The soil strength parameters used were based on typical values for the anticipated soils. The input strength parameters were: Table 1 Stability Analysis Strength Parameters Material Moist Unit Weight (pcf) Saturated Unit Weight (pcf) Effective Cohesion Effective Friction Angle (degrees) Overburden material 123 128 0 30 Sand and gravel with Cobbles 149 155 0 38 Stockpile 120 125 0 28 TETRA TECH Mr. Sean Frisch July 19, 2010 Page 3 The scenarios were modeled with a general section including 15 feet of overburden silty sand overlying sand and gravel with cobbles. The scenarios are shown in Table 2, Table 2 — Structures within 200 feet of mine limit Structure Structure Owner Structure Location Colorado State Highway 82 Colorado Department of Transportation Located approximately 190 feet south of the southern mine limit in the southwest corner of the property. Highway 82 is located at an elevation equal to the proposed bottom elevation of the mine. Garfield County Road 103 (Crystal Springs Road) Garfield County Located approximately 150 feet west of the western mine limit in the southwestern corner of the property. At this location, County Road 103 is located at an elevation 40 feet above the proposed bottom elevation of the mine. A buried Telephone Line Qwest Corporation Located approximately 180 feet west of the western mine limit in the in the southwestern corner of the property. At this location, the telephone line is located at an elevation 40 feet above the proposed bottom elevation of the mine. A buried 10 -inch diameter gas flow line Rocky Mountain Natural Gas c/o SourceGas, LLC Located approximately 100 feet south of the southern mine limit. A gas meter associated with the buried 10 -inch gas flow line Rocky Mountain Natural Gas c/o SourceGas, LLC Located approximately 160 southeast of the southeast corner of the mine limit. Overhead electric service lines and associated poles Holy Cross Energy Located approximately 100 feet east of the eastern mine limit, along the eastern property line. The Basin Ditch Basin Ditch Company Located approximately 140 feet north of the northern mine limit. A private bridge spanning the Basin Ditch Clifford Cerise Ranch Company, LLLP Located approximately 140 feet north of the northern mine limit. An 18 -inch diameter irrigation pipe Clifford Cerise Ranch Company, LLLP Located approximately 95 feet south of the southern mine limit. Fence A Clifford Cerise Ranch Company, LLLP The most critical fence location near the 3:1 (H:V) highwall slope, approximately 140 feet north of the north mine limit. Fence B Clifford Cerise Ranch Company, LLLP The most critical fence location near the 1:1 (H:V) interbench highwall slope, approximately 10 feet east of the east mine limit of the silt pond. 1 — The closest fence lines to both the interbench slope and the 3:1 highwall configurations locations were considered the most critical. Stability analyses were run on randomly generated circles generated through the mine excavation and highwall, as well as at the nearby permanent structures. The Slope/W program calculated the Factors of Safety (FOS) using the ordinary, Bishop, Janbu, and Spencer Methods. The Spencer factor of safety correlates more closely with observations of actual slope failure, providing a realistic and more rigorous lot TETRA TECH Table 3 Stability Analysis Results Mr. Sean Frisch July 19, 2010 Page 4 Section Distance to Nearest Permanent Structure Highwall Configuration Factors of Safety Colorado State Highway 82 190 Bench NA' Garfield County Road 103 (Crystal Springs Road) 150 Bench 4.3 Buried telephone line 180 Bench4.3 Buried 10 -inch diameter gas flow line 150 Bench 2.0 Gas meter associated with the buried 10 -inch gas flow line 160 Bench 2.1 Overhead electric service lines and associated poles 100 Bench 1.6 Basin Ditch 140 3:1(H:V) 2.6 18" diameter irrigation pipe 95 Bench 1.5 Private bridge spanning the Basin Ditch 140 3:1(H:V) 2.6 Fence A2 140 3:1(H:V) 2.6 Fence B2 10 Bench 1.4 I — The elevation of CO Highway 82 is at the s3nie elevation as the proposed bottom elevition of the mine. No failure surface could be generated. 2 — The closest fence lines to both the imerbench slope and the 3:1 highwall configurations locations were modeled. The minimum setbacks are equal to the distances in the table above. All FOS are 1.4 or greater. Mining, following these minimum setbacks, should not pose a hazard to nearby structures. LIMITATIONS Our review is based on regional geologic mapping, present mining plans, exploratory boring data, known structure locations, and stability analyses using typical soil strength parameters. Should the mining plans change, subsurface conditions vary or structure locations differ from those portrayed in this letter, we should be contacted in order to re-evaluate the potential affects on man-made structures.
