Rollover of Discovery 2010 Flow-Through Limited Partnership

CALGARY, Jan. 31, 2013 /CNW/ - Middlefield Mutual Funds Limited (the "Mutual Fund") is pleased to announce that it has completed the rollover of Discovery 2010 Flow-Through Limited Partnership (the "Partnership") into the Groppe Tactical Energy Class (MID125) mutual fund. The Partnership was dissolved on January 31, 2013.

Partnership investors can determine their Groppe Tactical Energy Class shareholdings by multiplying the number of units they held in the Partnership by 1.03710879. Shares of Groppe Tactical Energy Class have now been credited to the accounts of beneficial holders of Partnership units. The adjusted cost base of the shares of the Groppe Tactical Energy Class distributed to Partnership investors is $5.87055096 per share. There are no fees charged on the rollover into the Mutual Fund, nor on redemptions of Mutual Fund shares. For those investors looking for a tax shelter in 2013, please be advised that MRF 2013 Resource Limited Partnership is currently available for investment.

The Groppe Tactical Energy Class actively invests in the oil and gas sector and in 2012 received a Lipper Fund Award and was recognized as Canada's #1 natural resource equity fund over a 1-year period. In addition, Middlefield's Income Plus Class Mutual Fund received two Lipper Fund Awards and was recognized as Canada's #1 neutral balanced mutual fund over the 3-year and 10-year periods ended October 31, 2011.

The transfer to the Mutual Fund was a tax-free exchange which means that no disposition occurred and therefore no capital gains tax is payable as a result of the rollover. Investors can continue to defer the capital gains tax liability that arises upon disposition of their investment by retaining the shares of the Mutual Fund, which currently offers nine asset classes into which they can switch tax-free. These asset classes provide significant flexibility to suit numerous investment objectives including income, growth and safety of capital. In addition to Groppe Tactical Energy and Income Plus, the other classes currently offered are ActiveIndex REIT, Precious Metals, Canadian High Yield, Canadian Dividend Growth, Global Agriculture, Uranium Focused Metals and Short-Term Income.

Investors should consult their advisors to determine the strategy that is most suitable for them for the achievement of their own personal needs and objectives.
