Forecast product prices and operating costs were escalated at a rate of 2.0% per year beyond 2013. The exchange rate used for the US/Canadian dollar was 0.90. The forecast prices presented above utilize Paddock Lindstrom's price forecast as at December 31, 2008.

FD&A costs (including acquisition and divestment reserve volumes and capital) on a proven basis were $14.18 per boe, and on a proven and probable basis were $11.61 per boe. The capital assumptions in these calculations include all capital, including capital associated with acquisitions and divestments as well as changes in future capital contained in the reserves report relating to proved or proved and probable reserves. Reserve volumes and are net of all additions and technical revisions.

F&D costs (excluding acquisition and divestment reserve volumes and capital) on a proven basis were $38.94 per boe, and on a proven and probable basis were $20.52 per boe. The capital assumptions in these calculations includes all capital as well as changes in future capital contained in the reserves report relating to proved or proved and probable reserves, but specifically excludes reserve volumes and capital associated with acquisitions and divestments. Reserve volumes and are net of all additions and technical revisions, excluding reserves due to acquisitions or divestments.

Excluding acquisitions and dispositions, proven plus probable reserve additions (including revisions and after production) were 179 mboe, replacing approximately 115% of Tango's production volumes during 2008.

Due to the divestment of the Cecilia property, Tango's proved plus probable petroleum and natural gas reserves (net before royalty) decreased 25% after production to 1,898 mboes as at December 31, 2008. The Cecilia sale comprised 458 mboe proven and 284 mboe probable reserves for total consideration of $9.5 million (after adjustments), or $20.80 per barrel of oil equivalent of proven reserves and $12.84 per barrel equivalent of proven plus probable reserves.

Tango estimates that its net asset value (as defined by the 10% before tax net present value of reserves plus positive working capital at December 31, 2008 plus independent land and seismic value) is $0.25 per share based on proven reserves, and $0.49 per share based on proven plus probable reserves.

Additional reserve information will be included in Tango's NI 51-101 report, which will be filed on SEDAR.

Operations Update
-----------------

Tango announces that current sales volumes are approximately 450 boepd. Additional sales volumes are expected from a new well at Beaton and the tie in of an additional well at Worsley prior to the end of the second quarter of 2009. At Quaich, the discovery well at 3-3 has been on stream since December 21, 2008 at restricted rates of 330 boepd gross sales in which Tango has a 60% working interest. An additional well has been licensed at Quaich and the operator is expected to drill this well during the 3rd or 4th quarter of 2009.

Outlook
-------

In a business environment of restricted capital availability and reduced cash flows, Tango is currently focused on corporate and property acquisition opportunities. Tango will continue to maintain existing properties and production through prudent investments where the deployment of capital results in immediate economic returns. In addition, Tango is pursuing industry partners to drill existing deeper prospects and rationalize existing assets through swaps.

The TSX Venture Exchange has not reviewed and does not accept
responsibility for the adequacy or accuracy of this release.

This release contains forward-looking information. By their nature, forward-looking statements involve assumptions and known and unknown risks and uncertainties that may cause actual future results to differ materially from those contemplated. These risks include such things as volatility of oil and gas prices, commodity supply and demand, fluctuations in currency and interest rates, ultimate recoverability of reserves, timing and costs of drilling activities and pipeline construction, new regulations and legislation and availability of capital. Tango does not undertake to update any of such forward-looking statements. Please refer to Tango's Annual Report for more detail as to the nature of these risks and uncertainties. Although Tango believes that the expectations represented by these forward looking statements are reasonable, there can be no assurance that such expectations will prove to be correct.

BOE's may be misleading, particularly if used in isolation. In accordance with NI 51-101, a barrel of oil equivalent (boe) conversion ratio of 6 mcf: 1 boe is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. Abbreviations used are defined as flows: m$ (thousands of dollars); mcf (thousand standard cubic feet); mmcf (million standard cubic feet); mboe (thousands of barrels of oil equivalent); mmBTU (million British Thermal Units).

The aggregate of the exploration and development costs incurred in the most recent financial year and the change during that year in the estimated future development costs generally will not reflect total finding and development costs related to reserve additions for that year.
