 (1)
    
    Backlog is anticipated contract revenue from projects for which award is either in hand or
assured.(2)
    
    EBITDA is earnings before net interest, income taxes and depreciation and amortization. EBITDA
as
presented may not be comparable to other similarly titled measures reported by other companies. The
Company believes EBITDA is a useful measure of evaluating its financial performance because of its
focus on the Companys results from operations before net interest, income taxes, depreciation and
amortization. EBITDA is not a measure of financial performance under generally accepted accounting
principles. However, EBITDA is a common alternative measure of operating performance used by
investors, financial analysts and rating agencies. A reconciliation of EBITDA to net income is
included in
the exhibit to this release.(3)
    
    Loss before special items (and the related amounts per share), a non-GAAP financial measure,
excludes
special items that management believes affect the comparison of results for the periods presented.
Management also believes results excluding these items are more comparable to estimates provided by
securities analysts and therefore are useful in evaluating operational trends of the company and
its
performance relative to other engineering and construction companies.
