Introductory Note.

On February 13, 2019 (the “Closing Date”), pursuant to the Agreement and Plan of Merger, dated as of October 31, 2018 (the “Merger Agreement”), by and among Newfield Exploration Company, a Delaware corporation (the “Company” or “Newfield”), Encana Corporation, a Canadian corporation (“Encana”), and Neapolitan Merger Corp., a Delaware corporation and an indirect, wholly-owned subsidiary of Encana (“Merger Sub”), Merger Sub was merged with and into the Company (the “Merger”), with the Company surviving the Merger as an indirect, wholly-owned subsidiary of Encana. The events described in this Current Report on Form 8-K took place in connection with the completion of the Merger.

In connection with the closing of the Merger, the Company terminated all outstanding commitments under that certain Amended and Restated Credit Agreement, dated as of March 23, 2018, among Newfield Exploration Company, JPMorgan Chase Bank, N.A., as the administrative agent, Wells Fargo Bank, National Association, The Bank of Nova Scotia, Houston Branch and The Bank of Tokyo Mitsubishi UFJ, Ltd., as co-syndication agents, and BMO Harris Bank N.A., Citibank, N.A., Credit Suisse AG, Cayman Islands Branch, Sumitomo Mitsui Banking Corporation and U.S. Bank National Association, as co-documentation agents, and the lenders party thereto (the “Credit Agreement”). In connection with the closing of the Merger, the Company repaid in full all outstanding indebtedness of the Company and its subsidiaries for borrowed money or in respect of loans and advances under the Credit Agreement, and terminated such agreement, including all undrawn commitments thereunder.

The descriptions of the Credit Agreement contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017, as updated in its subsequent Quarterly Reports on Form 10-Q, are incorporated in this Item 1.02 by reference.

As a result of the Merger, each outstanding share of common stock, par value $0.01 per share, of Newfield was converted into the right to receive 2.6719 common shares, no par value, of Encana (the “Encana Shares”), as well as cash in lieu of any fractional shares of Encana that otherwise would have been issued (collectively, the “Merger Consideration”).

The issuance of Encana Shares in connection with the Merger was registered under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to Encana’s registration statement on Form S-4 (File No. 333-228666). The joint proxy statement/prospectus (the “Joint Proxy Statement/Prospectus”) filed by Encana pursuant to Rule 424(b)(3) under the Securities Act contains additional information about the Merger.

The foregoing description of the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is subject to and qualified in its entirety by reference to the Merger Agreement, a copy of which was included as Annex A to the Joint Proxy Statement/Prospectus, and is incorporated by reference in this Current Report on Form 8-K.

The information set forth under the Introductory Note, the Joint Proxy Statement/Prospectus and Item 5.01 of this Current Report on Form 8-K is incorporated by reference into this Item 2.01.

Prior to the effective time of the Merger (the “Effective Time”), shares of the Company common stock were listed and traded on the New York Stock Exchange (the “NYSE”) under the trading symbol “NFX.” As a result of the Merger, the Company no longer fulfills the listing requirements of the NYSE. On the Closing Date, the Company notified the NYSE that the Merger had been completed and requested that the NYSE: (i) suspend trading of the Company common stock on the NYSE; (ii) withdraw the Company common stock from listing on the NYSE following the close of trading on the Closing Date; and (iii) file with the SEC a notification of removal from listing on Form 25 to delist the Company common stock from the NYSE and deregister the Company common stock under Section 12(b) of the Securities Exchange Act of 1934 (the “Exchange Act”). Upon the Company’s request, the

2

NYSE filed a Form 25 to delist the Company common stock from the NYSE and deregister the Company common stock under Section 12(b) of the Exchange Act. The Company common stock ceased being traded following the close of trading on the Closing Date and will no longer be listed on the NYSE. Additionally, the Company intends to file with the SEC certifications on Form 15 under the Exchange Act requesting the deregistration of the Company common stock under Section 12(g) of the Exchange Act and the suspension of the Company’s reporting obligations under Section 13(a) and Section 15(d) of the Exchange Act with respect to the Company common stock as promptly as practicable.

The information set forth in Items 2.01, 3.01, 5.01 and 5.03 of this Current Report on Form 8-K is incorporated by reference into this Item 3.03.

In addition, (i) all outstanding Newfield restricted stock awards were cancelled and converted into the right to receive the Merger Consideration; (ii) all outstanding Newfield restricted share units were cancelled and (a) each holder of Newfield restricted stock units that had a cash settlement feature became entitled to receive, on a fully vested basis, a cash payment of equivalent value to the Merger Consideration, based on the recent trading price of Encana common shares and (b) each holder of Newfield restricted stock units that had a share settlement feature became entitled to receive, on a fully vested basis, the Merger Consideration; (iii) all outstanding Newfield performance share units were cancelled and converted 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 (the “Board”), not to exceed 200% per Newfield performance share unit; and (iv) any shares of Newfield notional stock that were held in connection with Newfield’s Nonqualified Deferred Compensation Plan were converted into the right to receive a cash payment of equivalent value to the Merger Consideration, based on the recent trading price of Encana common shares.

As a result of the Merger, a change in control of Newfield occurred, and Newfield is now an indirect, wholly-owned subsidiary of Encana.

The information set forth in Items 2.01, 3.03 and 5.02 of this Current Report on Form 8-K is incorporated by reference into this Item 5.01.
