Not for distribution to U.S. newswire services or dissemination in the United States

Cenovus Energy Inc. (TSX: CVE) (NYSE: CVE) ("Cenovus" or the "Selling Shareholder") and Headwater Exploration Inc. (TSX: HWX) ("Headwater" or the "Company") announced today that they have entered into an agreement with Peters & Co. Limited and BMO Capital Markets (the "Lead Underwriters"), on behalf of a syndicate of underwriters (together with the Lead Underwriters, the "Underwriters"), pursuant to which the Underwriters have agreed to purchase, on a bought deal basis, from Cenovus, through its wholly owned subsidiary, Cenovus Marten Hills Partnership (the "Partnership"), 25,000,000 common shares of the Company (the "Common Shares") at a price of $4.55 per Common Share (the "Offering Price") for total gross proceeds to the Selling Shareholder of $113,750,000 (the "Offering"). The Selling Shareholder has granted the Underwriters an option to purchase an additional 15% of the Common Shares issued under the Offering (3,750,000 Common Shares) at the Offering Price exercisable to cover over-allotments and for market stabilization purposes in whole or in part at any time until 30 days after the closing. The Company will not receive any of the proceeds from the Offering or the over-allotment option, if exercised.

Cenovus currently holds, indirectly through the Partnership, 50,000,000 Common Shares, representing approximately 24.7% of the issued and outstanding Common Shares and 15,000,000 purchase warrants exercisable at $2.00 per Common Share until December 2, 2023. Following the closing of the Offering, Cenovus will indirectly hold 25,000,000 Common Shares (21,250,000 Common Shares assuming full exercise of the over-allotment option), representing approximately 12.3% of the issued and outstanding Common Shares (10.5% assuming full exercise of the over-allotment option) and 15,000,000 warrants to purchase Common Shares. Assuming exercise of the warrants held by Cenovus, following closing of the Offering, Cenovus would indirectly hold 40,000,000 Common Shares (36,250,000 Common Shares assuming full exercise of the over-allotment option), representing approximately 18.4% of the issued and outstanding Common Shares (16.7% assuming full exercise of the over-allotment option).

Cenovus is selling the Common Shares as part of its plan to reduce net debt levels towards its $10 billion interim target and accelerate shareholder returns. Through its active development plan and early success, Headwater has accelerated the value generated from the Marten Hills asset and continues to progress its exploration program. The Offering will expand Headwater's free-trading float and is expected to provide new and existing shareholders with enhanced trading liquidity.

The Common Shares will be offered by way of a short form prospectus qualifying them for distribution in all provinces of Canada, excluding Quebec. Private placement offerings in the United States will be made to "qualified institutional buyers" pursuant to Rule 144A of the United States Securities Act of 1933 and with certain accredited institutional investors under Regulation D.
