Royal Dutch Shell plc Announces a Proposal to Acquire all the Outstanding Shares
in Duvernay Oil Corp.

THE HAGUE, The  Netherlands, July 14/PRNewswire-FirstCall/ --     Royal Dutch
Shell plc ("Shell") (NYSE: RDS.A) (NYSE: RDS.B) announced
today a proposal by its wholly owned subsidiary Shell Canada Limited, to
offer (the "Offer") to acquire all of the outstanding shares of Duvernay Oil
Corp. ("Duvernay").

    The Offer will be a cash offer of C$83 per share of Duvernay. The Offer
would value Duvernay's fully diluted share capital at approximately C$5.9
billion, including debt, and would be a 36% premium over the average share
price over the last 30 days.

    The Board of Duvernay has voted unanimously to recommend the Offer to
shareholders.

    In connection with the Offer, directors and officers of Duvernay have
entered into lock-up agreements pursuant to which they have agreed to tender
all of their shares in connection with the Offer, subject to certain
exceptions, representing in aggregate some 18.1% of the fully diluted share
capital of Duvernay. In addition, Duvernay has agreed in certain
circumstances to pay a non-completion fee of C$120 million, and the parties
have agreed to customary non-solicitation covenants.

    Duvernay is a leading acreage holder in the Western Canadian
Sedimentary Basin. The company has some 1,800 square kilometers (~450,000
acres) of landholdings there, including positions in the emerging Montney
tight gas trend. Duvernay has reported over 25,000 barrels oil equivalent per
day (boe/d) of production, predominantly in natural gas, with plans to
increase production to around 70,000 boe/d by 2012. Shell has around 80,000
boe/d of tight gas production in North America, and has been building its
acreage positions for future growth.

    Shell's Chief Executive Jeroen van der Veer commented "Shell
has a proven track record in North America tight gas activities. Duvernay
could become a valuable part of the Shell portfolio, where we can add value
through technology and scale. The combination of Duvernay's acreage with
Shell's proven operating experience and financing capabilities make this
transaction attractive to all shareholders."

    Full details of the Offer will be included in a take-over bid
circular and related documents, which will be filed shortly with securities
regulators and mailed to Duvernay shareholders.

    The Offer is subject to regulatory approvals and other
conditions contained in the formal offer documents, including the tendering
of at least two-thirds of Duvernay's fully diluted share capital.
