Merger Agreement

On October 31, 2018, Encana Corporation, a Canadian corporation (“Encana”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Newfield Exploration Company, a Delaware corporation (“Newfield”) and Neapolitan Merger Corp., a Delaware corporation and an indirect, wholly-owned subsidiary of Encana (“Merger Sub”), pursuant to which Merger Sub will merge with and into Newfield (the “Merger”), with Newfield surviving the Merger as an indirect, wholly-owned subsidiary of Encana.

The Merger Agreement provides, subject to the terms and conditions of the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each outstanding share of capital stock, par value $0.01 per share, of Newfield shall automatically be converted into the right to receive 2.6719 common shares, no par value, of Encana, as well as cash in lieu of any fractional shares of Encana that would otherwise have been issued (collectively, the “Merger Consideration”).

Encana and Newfield intend that, for U.S. federal (and applicable state and local) income tax purposes, the Merger will be treated as a taxable acquisition of Newfield common stock by an indirect subsidiary of Encana.

Governance

In connection with the Merger, Encana and Newfield have agreed that two members of the Newfield board of directors (the “Newfield Designees”), to be mutually agreed by Encana and Newfield, will be appointed to the Encana board of directors immediately after the Effective Time of the Merger. Additionally, from the closing of the Merger until immediately following the first annual meeting of Encana shareholders that occurs after the Closing, Encana shall take necessary action to cause the Newfield Designees, or individuals designated by the Newfield Designees, to be appointed to the Encana board of directors as more fully described in the Merger Agreement.

Conditions to the Merger

The completion of the Merger is subject to various customary closing conditions, including, among other things, (i) the receipt of certain approvals of the Encana shareholders and the Newfield stockholders, (ii) the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, (iii) the effectiveness of the registration statement on Form S-4 that Encana is obligated to file with the Securities and Exchange Commission (“SEC”) in connection with the issuance of Encana common shares in the Merger, (iv) the authorization for listing of the shares of Encana common shares to be issued in the Merger on the New York Stock Exchange and the Toronto Stock Exchange, (v) the accuracy of each party’s representations and warranties (subject to certain materiality qualifiers) and compliance by each party with its covenants under the Merger Agreement in all material respects and (vi) the absence of legal restraints prohibiting or restraining the Merger.

Termination Rights

The Merger Agreement contains certain termination rights for both Newfield and Encana including, among other things: (i) by Newfield, in the event the Newfield board of directors effects a Change of Recommendation (as defined in the Merger Agreement) and substantially concurrently therewith Newfield enters into an acquisition agreement providing for a Superior Proposal (as defined in the Merger Agreement); (ii) by Encana, in the event the Encana board of directors effects a Parent Change of Recommendation (as defined in the Merger Agreement) and substantially concurrently therewith Encana enters into an acquisition agreement providing for a Parent Superior Proposal (as defined in the Merger Agreement); (iii) by Newfield or Encana, if Newfield fails to obtain the requisite approval of its stockholders necessary for the Merger; (iv) by Newfield or Encana, if Encana fails to obtain the requisite approval of its shareholders related to the issuance of Encana common shares in the Merger; (v) by Newfield or Encana, if the other party breaches or fails to perform any of its representations, warranties or covenants in the Merger Agreement that cannot be or is not cured in accordance with the terms of the Merger Agreement and such breach or failure to perform would cause applicable closing conditions not to be satisfied; (vi) by Newfield, in the event that the Encana board of directors makes a Parent Change of Recommendation or upon any material breach by Encana of the non-solicitation covenant (as discussed further below under “—No Solicitation”) and (vii) by Encana, in the event that the Newfield board of directors makes a Change of Recommendation or upon any material breach by Newfield of the non-solicitation covenant. If the Merger Agreement is terminated in accordance with clause (i) or clause (vii), then Newfield shall be required to pay Encana a termination fee of $150,000,000 (the “Termination Fee”) and if the Merger Agreement is terminated in accordance with clause (ii) or clause (vi), then Encana shall be required to pay Newfield a termination fee of $300,000,000 (the “Parent Termination Fee”), provided that a Termination Fee or Parent Termination Fee will only be payable in connection with a breach of the non-solicitation covenant if, after the date of the Merger Agreement but prior to the termination thereof, an acquisition proposal is made to the breaching party’s board of directors or otherwise publicly announced or known and the breaching party, among other things, enters into or consummates an alternative transaction within 12 months of termination of the Merger Agreement. If the Merger Agreement is terminated in accordance with clauses (iii), (iv) or (v) in circumstances where the Termination Fee or Parent Termination Fee would not otherwise be payable, then Newfield or Encana, as the breaching party, shall be required to pay the non-breaching party $50,000,000 for costs fees and expenses incurred by such non-breaching party in connection with the Merger.

In addition to the foregoing termination rights, either party may terminate the Merger Agreement if the Merger has not been consummated on or prior to June 30, 2019 or if a governmental entity with a material connection to either Encana or Newfield issues a final, non-appealable order or decree permanently restraining, enjoining or prohibiting the transactions contemplated by the Merger Agreement. The parties may also mutually agree to terminate the Merger Agreement.

No Solicitation

Neither Encana, Newfield nor any of their respective affiliates is permitted, among other things, to solicit, initiate or knowingly encourage or facilitate, among other things, any inquiries, proposals or offers from any person which constitutes or may reasonably be expected to result in an Acquisition Proposal (as defined in the Merger Agreement) or engage in or participate in any discussions or negotiations regarding any such Acquisition Proposal. Notwithstanding this limitation, prior to receipt of certain approvals of a party’s shareholders, such party may, under certain circumstances, provide non-public information to and participate in discussions or negotiations with third parties with respect to certain unsolicited Acquisition Proposals that such party’s board of directors has determined in good faith, after consultation with its outside financial advisors and legal counsel, constitutes or would reasonably be expected to result in a superior proposal. Each party’s board of directors may change its recommendation to its shareholders (subject to the other party’s right to terminate the Merger Agreement following such change in recommendation) in response to an Acquisition Proposal that it has determined, after consultation with its outside financial advisors and legal counsel, constitutes a superior proposal or in response to an intervening event if, in either case, the board of directors determines in good faith that the failure to take such action would be reasonably be expected to be inconsistent with its fiduciary duties.

Treatment of Newfield Equity Awards

The Merger Agreement provides that: (i) all outstanding Newfield restricted stock awards will be cancelled and each holder of Newfield restricted stock awards will be entitled to receive, on a fully vested basis, the Merger Consideration; (ii) all outstanding Newfield restricted stock units will be cancelled and (a) each holder of Newfield restricted stock units that have a cash settlement feature will be entitled to receive, on a fully vested basis, a cash payment of equivalent value to the Merger Consideration, based on the volume weighted averages of the trading price

of Encana common shares on each of the five consecutive trading days ending on the trading day that is three trading days prior to the Effective Time (the “Encana Trading Price”) and (b) each holder of Newfield restricted stock units that have a share settlement feature will be entitled to receive, on a fully vested basis, the Merger Consideration; (iii) all outstanding Newfield performance share units will be cancelled and will convert into the right to receive the Merger Consideration, with the performance-based vesting conditions applicable to such Newfield performance stock units deemed achieved based on the determination of the compensation and management committee of the Newfield board of directors, not to exceed 200% per Newfield performance share unit; and (iv) any shares of Newfield notional stock held in connection with Newfield’s Nonqualified Deferred Compensation Plan will convert into the right to receive a cash payment of equivalent value to the Merger Consideration, based on the Encana Trading Price.

The foregoing description of the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is qualified in its entirety by the actual Merger Agreement, a copy of which is filed as Exhibit 2.1 to this Current Report on Form 8-K and incorporated herein by reference.

The Merger Agreement contains representations, warranties and covenants by each of Encana, Merger Sub and Newfield. These representations, warranties and covenants were made solely for the purpose of the Merger Agreement and solely for the benefit of the parties to the Merger Agreement and:

Risks and uncertainties that may affect these business outcomes include: integration of Encana and Newfield and the ability to recognize the anticipated benefits from the combination of Encana and Newfield ability to obtain required shareholder and regulatory approvals for the transaction, timing thereof and risk that such regulatory approvals may result in the imposition of conditions that could adversely affect the expected benefits of the transaction; risk that the conditions to the transaction are not satisfied on a timely basis or at all and the failure of the transaction to close for any other reason; risks relating to the value of the Encana common shares to be issued in connection with the transaction; disruption to Encana’s and Newfield’s respective businesses that could result from the announcement of the transaction; variability and discretion of Encana’s board of directors to declare and pay dividends, if any; variability in the amount, number of shares and timing of purchases, if any, pursuant to the share repurchase program; commodity price volatility; counterparty and credit risk; impact of a downgrade in a credit rating, including to refinance debt required to be repaid because of a downgrade, and its impact on access to sources of liquidity; risks inherent in Encana’s corporate guidance and five-year plan; failure to achieve cost and efficiency initiatives; and other risks and uncertainties impacting Encana’s business, as described in its most recent Annual Report on Form 10-K and as described from time to time in Encana’s other periodic filings as filed on SEDAR and EDGAR.

Readers are cautioned that the assumptions, risks and uncertainties referenced above are not exhaustive. FLS are made as of the date of this news release and, except as required by law, Encana undertakes no obligation to update publicly or revise any FLS.
