An Invoice shall (i) state NSI’s project number, (ii) set forth the Milestone(s) that HPD has successfully achieved and (iii) set forth the Milestone Payment(s) which correspond to the completion of such Milestone(s).

8.5.2 Within fifteen days of its receipt of an Invoice, NSI shall provide written notice to HPD as to any reasonable objections it may have as to Milestones that HPD claims to have achieved. If NSI fails to provide written notice of any objections within such fifteen-day period, NSI shall be deemed to have acknowledged the successful completion by HPD of the Milestone(s) HPD claims to have achieved and shall further be deemed to have accepted the corresponding Invoice, unless HPD has failed to achieve a Milestone, or a component of a Milestone, that shall not have been then discoverable in the exercise of reasonable diligence; and in such case, NSI shall have a period of fifteen days to provide its notice in accordance with this Section 8.5.2 from NSI’s actual discovery of the issue. If NSI provides a reasonable objection (within the foregoing fifteen-day periods) as to the claim by HPD of completion as to any Milestone, HPD shall not be paid for such Milestone until the Milestone is in fact achieved or corrected; provided however, the remaining undisputed portion of the Invoice shall be deemed accepted by NSI. HPD may include such Milestone in the Invoice immediately following the date the Milestone is finally achieved.

8.5.3 NSI shall pay the undisputed portion of an Invoice within 30 days after submission of such Invoice. The effective date of the submission of an Invoice shall be deemed the day when NSI receives the Invoice from HPD.

8.5.4 If NSI objects to any amount(s) expressed in any Invoice within the time period set forth at Subparagraph 8.5.2, either Party may at any time refer such objection to the dispute resolution procedures set forth in Article 12.

8.6 Payment Upon Mechanical Completion.

8.6.1 At such time as HPD believes that it has achieved Mechanical Completion, HPD shall submit its final Invoice, which shall constitute the remaining amount of the Contract Sum to be paid by NSI to HPD for the performance of the Work (the “Final Payment”). Notwithstanding anything to the apparent contrary stated elsewhere in this Article 8 or this Agreement, NSI shall be entitled to withhold ten percent (10%) of the Final Payment, until such time as the Certificate of Mechanical Completion is signed or a determination of Mechanical Completion is made and the HPD LOC is established pursuant to Section 8.7.

8.6.2 Within fifteen days of its receipt of an Invoice for Final Payment, NSI shall provide written notice to HPD as to any reasonable objections it may have as to the achievement by HPD of Mechanical Completion. If NSI fails to provide written notice of any objections within such fifteen-day period, NSI shall be deemed to have acknowledged that the Project is Mechanically Complete and shall further be deemed to have accepted the corresponding Invoice, unless HPD has failed to achieve a Mechanical Completion because of an issue that shall not have been then discoverable in the exercise of reasonable diligence; and in such case, NSI shall have a period of fifteen days to provide its notice in accordance with this Section 8.5.2 from NSI’s actual discovery of the issue. If NSI provides a reasonable objection (within the foregoing fifteen-day periods) as to the claim by HPD of Mechanical Completion, HPD shall not be paid the Final Payment, if already paid, HPD shall hold applicable funds in escrow, until Mechanical Completion is in fact achieved; provided, however, the remaining undisputed portion of the Invoice shall be deemed accepted by NSI.

18. SITE CONDITIONS & HAZARDOUS SUBSTANCES

18.1 Unforeseeable Conditions. If HPD encounters conditions at the Project Site that HPD reasonably believes are Unforeseeable Conditions, notice by HPD as to the same shall be promptly given to NSI. If it is thereafter determined that such condition is in fact an Unforeseeable Condition, then HPD shall be entitled to an equitable adjustment in the Contract Sum or the Scheduled Mechanical Completion Date, or both, as provided in Article 15. If NSI disagrees with the assessment by HPD that Unforeseeable Conditions exist, it may refer such disagreement to the Dispute resolution procedures set forth in Article 12. In no event shall an Unforeseeable Condition be any matter within HPD’s warranty contained in Section 3.2 of this Agreement.

18.2 Hazardous Substances. (a) If, in the course of performance of the Work, HPD encounters on the Project Site any matter which it reasonably believes is a Hazardous Substance that may require response, removal, cleanup or other remedial action under applicable Environmental Laws, then HPD shall immediately suspend the Work in the area affected and report the condition to NSI by telephone and in writing. In any such event, the obligations and duties of the Parties hereto shall be as follows:

(i) If it is determined that such condition involves an Existing Hazardous Substance, then HPD shall have no obligation with respect to such condition, and NSI shall, at its sole cost and expense, perform any response, removal, cleanup or other remedial action required by applicable Environmental Laws;

(ii) If it is determined that such condition involves a Hazardous Substance introduced to the Project Site by HPD or its Subcontractors, then any response, removal, cleanup or other remedial action required by applicable Environmental Laws shall be performed by HPD at its sole cost and expense; or

(iii) If, by agreement of the parties or in accordance with Article 12, it is determined that the condition does not involve a Hazardous Substance that requires response, removal, cleanup or other remedial action under applicable Environmental Laws, HPD shall resume the portion of the Work that had been suspended. Such time period involved in determining that the condition did not involve a Hazardous Substance that required response, removal, cleanup or other remedial action shall constitute an Excusable Event.

The Parties acknowledge and agree that HPD shall not commence or continue any construction activities on any portion of the Project Site on, in or under which remedial actions are to be (or are being) performed until such remedial actions are to the point where construction activities will not interfere with such remedial actions, as evidenced by appropriate certifications from the applicable environmental engineer and/or remediation contractor and any required approvals of any applicable Governmental Authorities. If NSI disagrees with the belief by HPD that a Hazardous Substance requiring remediation exists, it may refer such disagreement to the dispute resolution procedures set forth in Article 12; provided, however, HPD shall have no obligation to continue work until such time as the Dispute is resolved.

(b) NSI shall indemnify, defend and hold harmless HPD from and against any and all claims, demands, suits, liabilities, causes of action, losses, costs, expenses, damages, fines and penalties, including, without limitation, court costs and reasonable attorneys’ fees, arising or resulting from the existence of Existing Hazardous Substances at the Project Site HPD shall indemnify, defend and hold harmless NSI from and against any and all claims, demands, suits, liabilities, causes of action, losses, costs, expenses, damages, fines and penalties, including, without limitation, court costs and reasonable attorneys’ fees, arising or resulting from any Hazardous Substances which were introduced to, or exacerbated at, the Project Site by HPD or any of its Subcontractors. The preceding indemnification, defense and hold harmless obligations shall survive the termination or expiration of this Agreement.

(c) The parties acknowledge that neither HPD nor NSI have provided the other Party with any notice of the presence of any Existing Hazardous Substances at the Project Site arising out of HPD’s work conducted pursuant to the Engineering Services Agreement dated March 30, 2009.

EXHIBIT H

Herein is the agreed to methodology for Calculating the Contract Sum. The percentage values (if provided) are agreed to and serve as the basis for the overall calculation.

Item	Value
Estimated Project Costs (Equipment, Material, Freight, Engineering, Construction Equipment and Labor, etc) (A)	$2,913,000
HPD Fixed Fee (B)	$1,513,000
A + B = Contract Sum	$4,426,000
Project Contingency	$174,000

Project Savings and Cost Overruns are calculated at Final Completion based upon the actual Total Project Cost.

The Estimated Project Costs are subject to adjustment for Change Orders. Any increase or decrease due to a Change Order shall result in a corresponding increase or decrease of the HPD Fixed Fee by thirty percent (30%) of the value of the Change Order.

EXHIBIT I – Sample Calculation

The follow are sample calculation to illustrate how the Adjusted Total Contract Sum will be calculated.

Example 1

Total Project Cost $3,200,000

Cost Overruns = $3,200,000 – ($2,913,000+$172,500) = $114,500

Adjusted Final Contract Sum = Contract Sum ($2,913,000+$1,513,000) + Contingency ($172,500) + Cost Overruns ($113,000) = $4,713,000

Example 2

Total Project Cost $2,800,000

Change Orders = $100,000

Revised Estimated Project cost = $3,013,000

Revised HPD Fixed Fee = $1,513,000 + $30,000 = $1,543,300

Project Savings = $2,913,000 - $2,800,000 = $113,000

Adjusted Final Contract Sum = Contract Sum ($3,013,000+$1,543,000)-Project Savings ($113,000) = $4,443,000

Example 3

Total Project Cost $2,900,000

Change Orders = ($200,000)

Revised Estimated Project cost = $2,713,000

Revised HPD Fixed Fee = $1,513,000 - $60,000 = $1,453,000

Cost Overruns = $2,900,000 - $2,713,000 = $187,000

Adjusted Final Contract Sum = Contract Sum ($2,713,000+$1,453,000) + Cost Overruns ($187,000) = $4,353,000
