|ITEM 15: | CONTROLS AND PROCEDURES
|-------- | -----------------------

Evaluation of
disclosure controls and procedures

Under the supervision and with the participation of management, including our President and Chief
Financial Officer, we have evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2007, as defined in Canada by Multilateral Instrument 52-109, Certification of Disclosure in Issuers Annual and Interim
Fillings and in the United States by Rule 13(a)-15(e) under the Securities Exchange Act of 1934, as amended, as of March 31, 2007. Based on this evaluation, and taking into account the compensating review procedures described below,
our President and Chief Financial Officer concluded that the design and operation of our disclosure controls and procedures were effective.

Internal Control over Financial Reporting (ICFR)

Internal control over financial reporting is a process
designed to provide reasonable assurance regarding the reliability of financial reporting and of the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Management is responsible for
establishing and maintaining adequate internal controls appropriate to the nature and size of the business to provide reasonable, but not absolute, assurance regarding the reliability of financial reporting for the Company.

In the course of preparing our 2007 financial statements, we identified a number of material weaknesses in our ICFR. A control deficiency is a material
weakness in ICFR if the deficiency, or a combination of control deficiencies is such that there is a reasonable possibility that a material misstatement of the Companys annual or interim consolidated financial statements will not be prevented
or detected.

We noted the following material weaknesses in ICFR as at March 31, 2007:



| |  |  | Revenue recognitiona formal process to track claims and unapproved change orders and sufficient monitoring controls over the completeness and accuracy of
forecasts, including the consideration within project changes subsequent to the end of each reporting period were not effectively implemented. The accounts that could potentially be affected by these deficiencies are revenue, project costs and their
related accounts.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Income taxesthere was a lack of review and monitoring controls as well as a lack of segregation of duties of the income tax function. The accounts that could
potentially be affected by these deficiencies are future income tax assets, future income tax liabilities and future income tax expense.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Accounts payable and procurementThe Company did not have an effectively implemented procurement process to track purchase commitments, reconcile vendor
accounts and accurately accrue costs not invoiced by vendors at each reporting date. The accounts that could potentially be affected by these deficiencies are accounts payable, accrued liabilities, project costs, unbilled revenue, equipments costs,
general and administrative costs and other expenses.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | IT General Controls (ITGCs)a number of deficiencies in ITGCs existed, including appropriate controls around spreadsheets and end user computing,
controls over access and accuracy of one of our systems, as well as general maintenance of access rights and nominal program change controls. When aggregated, these deficiencies represented a material weakness in ICFR.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In anticipation of providing an annual report on ICFR by March 31, 2008, management is currently
evaluating the effectiveness of our system of internal control over financial reporting based on the framework in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Changes in Internal Control over Financial Reporting

We are currently addressing these deficiencies through the implementation of the requirements of Section 404 of the Sarbanes-Oxley Act of 2002 in the United States and Multilateral Instrument 52-109 in Canada. We
are in the remediation phase of a procurement project in which we implemented the purchase order functionality in our financial systems and trained our staff in the effective use of purchase orders to track our commitments and to record our expenses
in a timely manner. We are implementing and testing a project controls improvement initiative over the claims and unapproved change orders process, as well as the completeness and accuracy of project forecasts. We are also in the final stages of
upgrading our enterprise resource management software, which includes addressing the ITGC deficiencies noted above.

We have added to our
finance staff, and in particular we now have in-house Canadian GAAP expertise and a working knowledge of U.S. GAAP, which is supplemented by outside expertise. We have created a Corporate Controller position and added a Corporate Accounting Manager
and Tax Manager. In addition, we have instituted standardized procedures for financial reporting and review, including the procedures by which general ledger transactions are closed, reviewed and consolidated. The redesign of and implementation of
all planned changes to our disclosure controls and procedures are not yet complete. Until the implementation of such corrective measures is complete, we are compensating for the identified weaknesses in ICFR by performing additional review
procedures.

Our target is to complete the above changes by March 31, 2008, the date as of which we will be required to provide
managements report on the effectiveness of internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act of 2002. Because most of the costs of implementing the above changes to internal control over financial
reporting have been incurred in anticipation of providing such report or due to required systems upgrades, we have not incurred material costs in connection with implementing corrective actions to correct identified internal control deficiencies.

As discussed above, there were changes in our ICFR since March 31, 2006 that have materially affected, or are reasonably likely to affect,
our ICFR.
