ESTRELLA INTERNATIONAL ENERGY SERVICES LTD. ANNOUNCES UPSIZING OF PREVIOUSLY
ANNOUNCED CONVERTIBLE DEBENTURE PRIVATE PLACEMENT

NOT FOR DISSEMINATION IN THE UNITED STATES OR THROUGH U.S. NEWSWIRES

CALGARY, Dec. 24 /CNW/ - Estrella International Energy Services Ltd. (TSX-V:EEN) ("Estrella" or the "Company") is pleased to announce an increase to the over-allotment option (the "Over-Allotment Option") of its previously announced private placement with Canaccord Genuity Corp. ("Canaccord Genuity") of 100 subscription receipts (the "Subscription Receipts") for aggregate gross proceeds of $10,000,000 (the "Offering").  Estrella has increased the Over-Allotment Option granted to Canaccord Genuity to solicit subscriptions for and offer for sale up to an additional 50 Subscription Receipts (the "Additional Subscription Receipts"), for additional gross proceeds of up to $5,000,000, at the same price and at the same terms as the Subscription Receipts.  The Over-Allotment Option shall expire on the Closing Date and if exercised in full would result in total gross proceeds of $15,000,000.

Upon closing of the acquisition by the Company of a controlling interest in a private South American company that owns three drilling and nine work-over rigs (the "Acquisition"), each Subscription Receipt will entitle the holder thereof to receive, without payment of additional consideration or further action, one unit ("Unit") at a price of $100,000 per Unit (the "Offering Price").  Each Unit consists of:  (a) $100,000 par value of one 5-year convertible subordinated unsecured debentures bearing a coupon interest rate of 12% per annum, payable semi-annually in arrears in cash or common shares (the "Convertible Debentures"); and (b) one common share purchase warrant (the "Warrant") entitling the holder to acquire 12,500 common shares of Estrella ("Common Shares") at $0.80 per Common Share, exercisable for a period of 5 years from the closing date of the Offering (the "Closing Date"). All of the securities issued in connection with the proposed Offering are subject to a hold period of four months and one day.

The principal amount of the Convertible Debentures, plus all accrued and unpaid interest is at the option of debentureholders convertible Common Shares at any time at a conversion price of $1.00 per share.

The principal amount of the Convertible Debentures, plus all accrued and unpaid interest will be redeemable, in whole or in part, at the option of Estrella without penalty, provided that the weighted average trading price of the Common Shares, for the 20 consecutive trading days ending five trading days preceding the date on which notice of redemption is given is not less than $1.50.  Estrella may satisfy its obligation to repay the principal amount of the Convertible Debentures on redemption or maturity, by payment in Common Shares with a deemed issue price equal to 95% of the current market price of the Common Shares on the TSXV or the TSX as applicable.

Estrella will use the net proceeds of the Offering to complete the Acquisition, and for working capital purposes.  Any net proceeds from the exercise of the Over-Allotment Option will be used to acquire additional shares of the private South American company pursuant to the Acquisition, and for additional general corporate purposes. More comprehensive information on the Acquisition will be disclosed in an subsequent press release.

The Offering is subject to certain conditions including normal regulatory approvals, including the approval of the TSX Venture Exchange.  The Closing Date of the Offering is anticipated to occur on or about January 18, 2011.
