"Our results for the fourth quarter are very satisfying," said David Deacon, STT's CEO. "Our gross margins have improved as a result of effective project execution, the expansion of parts and service revenues and improved buying practices, which we have been pursuing aggressively."

He continued, "As mentioned in our last quarterly report, we continue to have a relatively cautious outlook on the overall economy and particularly its impact on commodity pricing (which has softened) and therefore may cause some delays or short term postponement of some development projects. As well, the lack of clarity on the pipeline issues for the oil sands is creating some easing of activity there. As a result we have taken steps to continue to improve margins and to expand our geographic reach in order to counter any softness in our markets due to these broader economic issues."

Potentially Dilutive Securities:

As at December 31, 2012 and 2011, the following potentially dilutive securities were excluded from the calculation of earnings per share since their exercise prices exceeded the average market value of the Company's common shares for the period:

Caution Regarding Forward-Looking Information and Non-IFRS Measures

Forward-Looking Information

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 the Company. 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 the Company 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 incorrect. These forward-looking statements are made as of the date of this press release, and none of STT nor its directors assume any obligation to update or revise them to reflect new events or circumstances. Undue reliance should not be placed on forward-looking statements.

Non-IFRS Measures

The term "EBITDA" is a financial measure used in this document which is not a standard measure under International Financial Reporting Standards ("IFRS"). The Company's method of calculating EBITDA may differ from the methods used by other issuers. Therefore, STT'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 IFRS before depreciation, amortization of intangible assets, gain or loss on disposal of property and equipment, interest expense, accretion expense, special charges and recoveries, stock compensation 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-IFRS measure, is not an alternative to measures under IFRS 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.

The term "backlog" is a financial measure used in this document which is not a standard measure under IFRS. The Company's method of calculating backlog may differ from the methods used by other issuers. Therefore, STT's measure of backlog, as presented in this press release, may not be comparable to similar measures presented by other issuers. Backlog is the value of revenue remaining to be earned from purchase orders received from customers. The projects represented in backlog are executed according to a schedule agreed with each customer, which could range in duration from one month to eighteen months. Revenues are earned on a percentage of completion basis. Management uses this measure to i) monitor the Company's success in securing new orders, and ii) gauge the likelihood of meeting revenue objectives in future periods.

Investors are cautioned that backlog, as a non-IFRS measure, is not an alternative to measures under IFRS 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.
