Caution Regarding Forward-Looking Information and Non-GAAP Measures

This news release contains certain forward-looking statements. These
statements relate to future events or future performance and reflect
management's current expectations and assumptions regarding the growth,
results of operations, performance, and business prospects and
opportunities. Such forward-looking statements reflect management's
current beliefs and expectations and are based on information currently
available to management of Semcan. In particular, statements regarding
the future operating results and economic performance are forward-looking
statements. Forward-looking statements involve significant risks and
uncertainties. A number of factors could cause actual events or results
to differ materially from the events and results discussed in the
forward-looking statements, including risks outlined under "Risk Factors"
in our Annual Information Form, which is posted at www.sedar.com. In
evaluating these statements, investors should specifically consider
various factors, including such risks as Investment Risk; Business
Valuations; Condition of Capital Markets; Dependence on Key Personnel;
General Economic Factors; Interest Rate Risk; Competition; and Reliance
on Key Suppliers. One or more of these "Risk Factors" could cause actual
events or results to differ materially from any forward-looking
statement. These factors should not be considered exhaustive. Although
the forward-looking statements contained in this press release are based
on what management of Semcan considers to be reasonable assumptions based
on information currently available to them, there can be no assurance
that actual events or results will be consistent with these
forward-looking statements, and management's assumptions may prove to be

Non-GAAP Measures

The term "EBITDA" is a financial measure used in this document which is
not a standard measure under Canadian generally accepted accounting
principles. Semcan's method of calculating EBITDA may differ from the
methods used by other issuers. Therefore, Semcan's measure of EBITDA, as
presented in this press release, may not be comparable to similar
measures presented by other issuers. EBITDA refers to net earnings
determined in accordance with generally accepted accounting principles,
before depreciation and amortization, interest expense, and income tax
expense. Management believes that EBITDA is a useful supplemental measure
of cash available for debt service, working capital, capital
expenditures, income taxes, and distribution. Investors are cautioned
that EBITDA, as a non-GAAP measure, is not an alternative to measures
under GAAP and should not, on its own, be construed as an indicator of
performance or cash flows, a measure of liquidity or as a measure of
actual return.

Neither TSX Venture Exchange nor its Regulation
Services Provider (as that term is defined in the policies of the TSX
Venture Exchange) accepts responsibility for the adequacy or accuracy of
this release.
