/NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES/

VANCOUVER, April 21 /CNW/ - TAG Oil Ltd. (TSX-V: TAO) (the "Company") is pleased to announce that, in connection with its previously announced overnight-marketed public offering (the "Offering"), it has entered into an underwriting agreement with a syndicate of underwriters led by GMP Securities L.P. and including Cormark Securities Inc. (collectively, the "Underwriters"), to sell 6,700,000 Units at a price of $2.60 per Unit (the "Offering Price") to raise gross proceeds of $17,420,000 pursuant to a short-form prospectus. Each Unit shall be comprised of one common share of the Company (a "Common Share") and one-half of one common share purchase warrant (a "Warrant"). Each whole Warrant will be exercisable at $3.60 and will entitle the holder thereof to acquire one Common Share for a period of 18 months following the closing of the Offering. The Company will file an amended and restated preliminary prospectus in all provinces of Canada, except Québec, to reflect the announced Offering terms.

The Company has also granted to the Underwriters an over-allotment option, exercisable in whole or in part for a period of 30 days from and including closing to purchase up to 15% of the Units sold pursuant to the Offering at the Offering Price for market stabilization purposes. The Underwriters may elect to exercise the over-allotment option to purchase additional Units only or additional Warrants only (in which case the additional Warrants will be acquired at $0.687 per Warrant and each full Warrant will remain exercisable at $3.60 for a period of 18 months), or any combination of additional Units and additional Warrants, so long as the aggregate number of additional Common Shares and additional Warrants issued upon the exercise of the over-allotment option does not exceed 1,000,000 Common Shares and 500,000 Warrants, respectively.

The Offering is expected to close on or about May 5, 2010 and is subject to certain customary conditions and regulatory approvals, including the approval of the TSX Venture Exchange.

The Company intends to use the net proceeds of the Offering to fund its exploration and development programs in the onshore portion of the Taranaki Basin and the East Coast Basin of New Zealand, for working capital and general corporate purposes.
