Except where provided otherwise in a Grant Agreement, Dividend Equivalent PSUs shall vest and be paid to the Participant at the same time as the Eligible PSUs to which they relate.

Adjustments. In the event of any stock dividend, stock split, combination or exchange of shares, capital reorganization, consolidation, spin-off or other distribution (other than normal cash dividends) of Corporation assets to shareholders, or any other similar changes affecting the Shares, proportionate adjustments to reflect such change or changes may be made with respect to the number of PSUs outstanding under the Plan, or securities into which the Shares are changed or are convertible or exchangeable may be substituted for Shares under this Plan, on a basis proportionate to the number of PSUs in the Participant’s PSU Account on some other appropriate basis, all as determined by the Board in its discretion.

OPTIONAL FUNDING OF PSU AWARDS

Contributions to Trust Fund. Except as otherwise provided in Section 11.8, the Corporation may, in its sole discretion, from time to time, on its own behalf and on behalf of such of its Affiliates as employ Participants, or any Affiliate may, make contributions to a Trust Fund in such amounts and at such times as may be specified by the Committee or the Board for the purpose of funding, in whole or in part, awards of PSUs which become payable to Participants pursuant to the Plan. For clarity, this Section 6 does not obligate the Corporation or any Affiliate to create a Trust Fund, nor to make contributions to a Trust Fund in any amounts or at all nor does it require the funding in whole or in part of any award of PSUs granted under this Plan.

Share Purchases. Where applicable, any purchases of Shares by the Trustee or otherwise pursuant to the Plan shall be made on the open market by a broker designated by the Trustee who is independent of the Corporation in accordance with Stock Exchange Rules and who is a member of the Stock Exchange. Subject to the foregoing part of this Section 6.2, any such designation may be changed from time to time. For clarity, this Section 6 does not obligate the Corporation or any Affiliate to purchase shares for the purposes of funding or settling, in whole or in part, awards of PSUs which may become payable to Participants pursuant to the Plan.

In such event, the Participant hereby waives any and all claims and/or rights to compensation or damages in consequence of the Termination of Employment (whether lawfully or unlawfully) or otherwise for any reason whatsoever insofar as these rights arise or may arise from the Participant ceasing to have rights to receive any cash payment or Shares in respect of PSUs granted under the Plan or any applicable Grant Agreement pursuant to this Section 7 or Section 8.

Eligibility Based on Achievement of Performance Criteria. PSUs granted to a Participant may only become Eligible PSUs upon satisfaction of the Performance Criteria referred to in Section 7.3, as determined by the Committee, in its discretion, and pursuant to the terms and conditions set forth in the Plan and the applicable Grant Agreement.

Determination of Performance Criteria. With respect to each grant of PSUs pursuant to Section 4.1, the Committee shall cause to be determined at the Committee Meeting Date applicable to a particular Performance Period, the Achieved Performance Criteria in respect of that Performance Period, as set out in the applicable Grant Agreement, for purposes of determining whether, and the extent to which (as applicable), such PSUs have become Eligible PSUs.

Eligible PSU Amount. With respect to the Eligible PSUs relating to a particular Performance Period, the Committee shall also cause to be determined at the applicable Committee Meeting Date, the Eligible PSU Amount relating to such Eligible PSUs, which amount shall be used to determine the value relating to such Eligible PSUs on the Vesting Date, subject to and in accordance with the terms and conditions of the Plan and the applicable Grant Agreement. The Committee may, in its discretion, determine whether to adjust the Eligible PSU Amount, and where such an adjustment is to be made, the adjustment mechanism in respect thereof.

VESTING AND PAYMENT OF PSU AWARDS

Vesting of Eligible PSUs. Subject to Sections 8.3, 8.4 and 8.5, Eligible PSUs relating to a grant of PSUs shall become Vested PSUs on the Vesting Date set forth in the applicable Grant Agreement. Except where the context requires otherwise, each Eligible PSU which vests pursuant to Section 8 shall be referred to for the purposes of the Plan and the applicable Grant Agreement as a “Vested PSU”. Eligible PSUs which do not become Vested PSUs in accordance with this Section 8 shall be forfeited by the Participant and the Participant will have no

(With amendments as of February 14, 2018 )

further right, title or interest in such PSUs. In such event, the Participant hereby waives any and all claims and/or rights to compensation or damages in consequence of the Participant’s Termination of Employment (whether lawfully or unlawfully, wrongful or otherwise) or otherwise for any reason insofar as these rights arise or may arise from the Participant ceasing to have rights to receive any cash payment or Shares in respect of PSUs granted under the Plan or any applicable Grant Agreement pursuant to this Section 8.

Payment in Cash or Shares. Subject to Sections 8.3, 8.4 and 8.5, each Participant shall be entitled to receive in cash or in Shares (or a combination thereof), as determined by the Committee, a payment in respect of the Vested PSUs relating to a particular Performance Period, as determined pursuant to Section 8.1, equal to the Participant’s Eligible PSU Amount in respect of such Performance Period (as may be adjusted pursuant to Section 7.4). Except as otherwise provided in Sections 8.3, 8.4, 8.5 and 11.8 and/or the applicable Grant Agreement(s), the cash or Shares in the amount determined pursuant to this Section 8.2 shall be paid or distributed to the Participant or their legal representative, as applicable, as soon as practicable following the Vesting Date set forth in the applicable Grant Agreement(s) and, in any event, prior to December 31 of the calendar year in which the applicable Vesting Date occurs, provided the Participant remains actively employed with the Corporation or an Affiliate, as applicable, on such date. Notwithstanding the foregoing or any other provision of the Plan, in respect of Vested PSUs, the Committee shall not settle in Shares any Vested PSUs for PSUs originally granted to the Participant after May 2, 2017 unless all approvals of such PSUs and/or the issuance of Shares in settlement of such PSUs, by shareholders or otherwise, as are required under Applicable Laws, are received prior to the applicable Vesting Date.

Death, Retirement, Period of Absence or Unpaid Leave of Absence.

Death. Unless otherwise determined by the Committee, in the event the Participant ceases to be an employee of the Corporation or an Affiliate, as applicable, by reason of the Participant’s death, the following shall apply:

Where the Participant’s date of death occurs on a date that is prior to the date the Participant attains the age of 60 years, then:

All Vested PSUs credited to the Participant’s PSU Account as of the Participant’s date of death, if any, if not already paid or distributed, shall be paid or distributed to the Participant’s legal representative in accordance with Section 8.2; and

Unless otherwise determined by the Committee, in the event of the Participant’s death prior to the Vesting Date relating to a grant of PSUs, PSUs granted to the Participant prior the Participant’s date of death which become Eligible PSUs pursuant to Section 7.2 shall vest and become payable to the Participant’s legal representative on the applicable Vesting Date in accordance with Section 8.2 in proportion to the number of calendar months (rounded up to the nearest whole month) following the applicable Grant Date before the date of death.

(With amendments as of February 14, 2018 )

Where the Participant’s date of death occurs on a date following the date that the Participant attains the age of 60 years, then:

All Vested PSUs credited to the Participant’s PSU Account as of the Participant’s date of death, if any, if not already paid or distributed, shall be paid or distributed to the Participant’s legal representative in accordance with Section 8.2;

Unless otherwise determined by the Committee, PSUs granted to the Participant prior to the Participant’s date of death which become Eligible PSUs pursuant to Section 7.2 shall vest and become payable to the Participant’s legal representative on the applicable Vesting Date in accordance with Section 8.2.

For clarity, no additional PSUs (whether pursuant to Section 4.1 or in the form of Dividend Equivalent PSUs) shall be granted to the Participant following the Participant’s date of death.

Retirement. Unless otherwise determined by the Committee, in the event the Participant ceases to be an employee of the Corporation or an Affiliate by reason of the Participant’s Retirement, the following shall apply:

Where the Participant’s Date of Retirement occurs on a date that is prior to the date the Participant attains the age of 60 years, then:

All Vested PSUs credited to the Participant’s PSU Account as of the Participant’s Date of Retirement, if any, if not already paid or distributed, shall be paid or distributed to the Participant in accordance with Section 8.2; and

Unless otherwise determined by the Committee, in the event of the Participant’s Retirement prior to the Vesting Date relating to a grant of PSUs under Section 4.1, PSUs granted to the Participant prior the Participant’s Date of Retirement which become Eligible PSUs pursuant to Section 7.2 shall vest and become payable to the Participant on the applicable Vesting Date in accordance with Section 8.2 in proportion to the number of calendar months (rounded up to the nearest whole month) following the applicable Grant Date before the Date of Retirement.

Where the Participant’s Date of Retirement occurs on a date that is on or after the date the Participant attains the age of 60 years, then:

All Vested PSUs credited to the Participant’s PSU Account as of the Participant’s Date of Retirement, if any, if not already paid or distributed, shall be paid or distributed to the Participant in accordance with Section 8.2;

Unless otherwise determined by the Committee, PSUs granted to the Participant prior to the Participant’s Date of Retirement which

of Encana Corporation

(With amendments as of February 14, 2018 )

become Eligible PSUs pursuant to Section 7.2 shall vest and become payable to the Participant on the applicable Vesting Date in accordance with Section 8.2.

For clarity, no additional PSUs (whether pursuant to Section 4.1 or in the form of Dividend Equivalent PSUs) shall be granted to the Participant following his Date of Retirement.

Period of Absence. Unless otherwise determined by the Committee, in the event of a Participant’s Period of Absence, PSUs credited to the Participant’s PSU Account immediately prior to such Period of Absence (and any related Dividend Equivalent PSUs) shall continue to be and become Eligible PSUs in accordance with the provisions of Section 7.2 and such Eligible PSUs (if any) shall continue to become Vested PSUs in accordance with Section 8.1 and the Participant shall be entitled to receive a payment relating to such Vested PSUs determined in accordance with Section 8.2 in respect of each Performance Period that ends during the period of such Period of Absence and thereafter, unless there occurs a Termination of Employment during a Performance Period, in which case the provisions of Section 8.4 shall apply, or unless the Participant’s death occurs during a Performance Period, in which case the provisions of Section 8.3.1 shall apply, or unless there occurs a Retirement of the Participant during a Performance Period, in which case the provisions of Section 8.3.2 apply.

Unpaid Leave of Absence. Unless otherwise determined by the Committee, in the event of a Participant’s Unpaid Leave of Absence, PSUs shall not become Eligible PSUs nor shall any PSUs become Vested PSUs during the Participant’s Unpaid Leave of Absence and the provisions of this Section 8.3.4 shall be applicable. The Participant shall only become entitled to have his PSUs become Eligible PSUs or, as applicable, his Eligible PSUs to become Vested PSUs on the date when the Participant’s Unpaid Leave of Absence ends and the Participant returns to active employment with the Corporation or an Affiliate. If the Participant does not return to active employment with the Corporation or an Affiliate from the Unpaid Leave of Absence, all unvested PSUs regardless of whether such PSUs are or are not Eligible PSUs shall not vest and shall be forfeited and cancelled and the Participant waives any and all right to compensation or damages in consequence of the Participant ceasing to have rights or be entitled to receive any cash or Shares under the Plan pursuant to this Section 8.3.4. Notwithstanding anything contained herein to the contrary, in no event shall this Section 8.3.4 cause a Section 409A Amount to be paid in a calendar year later than the calendar year such Section 409A Amount would have been paid had the Participant not been on an Unpaid Leave of Absence. For greater certainty, and notwithstanding any other provision in the Plan or a Grant Agreement, in no event shall this Section 8.3.4 cause a Section 409A Amount to be paid in a calendar year later than the calendar year such Section 409A Amount would have been paid had the Participant not been on an Unpaid Leave of Absence and instead such Section 409A Amount shall either be forfeited or paid on or before December 31 of the

(With amendments as of February 14, 2018 )

Termination of Employment. Unless otherwise determined by the Committee, a Participant shall not be entitled to any further grant or vesting of PSUs nor shall any PSUs become Eligible PSUs and the Participant shall not be entitled to any cash, Shares or other payment (including without limitation any Eligible PSU Amount) in respect of any unvested PSUs following a Termination of Employment. Except as otherwise provided in Section 8.5.2, PSUs (including any related Dividend Equivalent PSUs) which do not become Eligible PSUs or which do not vest in accordance with Section 8 prior to the Date Employment Ceases shall be cancelled without payment. The Participant waives any and all right to compensation or damages which may arise or may be deemed to arise in consequence of the Participant’s Termination of Employment (whether lawfully or unlawfully) or otherwise for any reason whatsoever insofar as those rights arise or may arise from the Participant ceasing to have rights or be entitled to receive any cash, Shares or other payment under the Plan pursuant to this Section 8.4. Any Vested PSUs credited to a Participant’s PSU Account as of the Date Employment Ceases shall be payable in accordance with Section 8.2.

Change in Control.

PSUs granted prior to February 14, 2018. With respect to PSUs granted to the Participant prior to February 14, 2018, notwithstanding any other provision of the Plan, unless otherwise specified by the Board or the Committee with respect to any portion of a PSU that does not constitute a Section 409A Amount, in the event of a Change in Control:

all Eligible PSUs credited to the Participant’s PSU Account immediately prior to such Change in Control shall become Vested PSUs immediately prior to the time of such Change in Control; and all PSUs credited to the Participant’s PSU Account that are not Eligible PSUs immediately prior to the time of such Change in Control shall become Eligible PSUs determined as if the Median Performance Criteria in respect of each applicable Performance Period have been achieved, and shall become Vested PSUs immediately prior to the time of such Change in Control;

as soon as practicable, and in any event within 30 days, following a Change in Control, (i) to the extent a Participant’s Vested PSUs are expressed in dollar value form in the PSU Account (including, without limitation, as a dollar value Eligible PSU Amount), the Participant shall receive a cash payment equal to such dollar value; and (ii) to the extent a Participant’s PSUs are expressed in PSU form in the PSU Account, the Participant shall receive in cash or in Shares (or a combination thereof), as may be determined by the Board or the Committee, a payment equal to the number of Vested PSUs (including as determined pursuant to Section 8.5.1(a)) credited to the Participant’s PSU Account at the time of the Change in Control (rounded up to the nearest whole number of Vested PSUs) multiplied by the price at which the Shares are valued for the purpose of the transaction or series of transactions giving rise to the

Performance Share Unit Plan for Employees

(With amendments as of February 14, 2018 )

Change in Control, or if there is no such transaction or transactions, the simple average of the closing price per Share on the applicable Stock Exchange on each day in the thirty day period ending on the date of the Change in Control (as applicable, the “Change in Control Value”); and

with respect to any Section 409A Amount (i) if the Change in Control constitutes a change in the ownership or effective control of a corporation, or a change in the ownership of a substantial portion of the assets of a corporation, as such terms are used in Section 409A of the Code and related regulations (a “409A Change of Control”), such Section 409A Amount shall be paid in accordance with Section 8.5.1(b), and (ii) if the Change in Control does not constitute a 409A Change of Control, such Section 409A Amount shall in all events be paid during the calendar year or years in which such amount would have been paid had there been no Change in Control.

PSUs granted on or after February 14, 2018. The provisions of this Section 8.5.2 shall apply to PSUs granted to the Participant on or after February 14, 2018, notwithstanding any other provision of the Plan.

In the event of a Change in Control, all Eligible PSUs credited to the Participant’s PSU Account immediately prior to such Change in Control shall become Vested PSUs immediately prior to the time of such Change in Control, and each PSU credited to the Participant’s PSU Account that are not Eligible PSUs immediately prior to the time of such Change in Control shall become Eligible PSUs with the Achieved Performance Criteria in respect of the applicable Performance Period deemed to be the greater of (x) the Median Performance Criteria and (y) the level of achievement of the Performance Criteria applicable to the Performance Period as determined by the Committee no later than the date of the Change in Control, taking in account performance through the latest date preceding the Change in Control as to which performance can, as a practical matter, be determined (but no later than the end of the Performance Period), and shall become Vested PSUs immediately prior to the time of such Change in Control, except to the extent that an award of PSUs meeting the requirements set out below in this Section 8.5.2(a) (such award, a “Replacement Award”) is provided to the Participant to replace such award of PSUs (each award of PSUs intended to be replaced by a Replacement Award, a “Replaced Award”) effective on or immediately after the time of such Change in Control. An award of PSUs shall meet the requirements of this Section 8.5.2(a) (and hence qualify as a Replacement Award) if (A) it has a value equal to the value of the Replaced Award as of the date of the Change in Control determined with reference to the Change in Control Value of the PSUs comprising the Replaced Award and the fair market value of the securities underlying the Replacement Award, (B) it relates to publicly traded equity securities of the Corporation, the entity surviving the Corporation following the Change in Control or the parent company of such surviving entity, (C) it contains terms relating to vesting that are substantially identical to those of the Replaced Award (except that for any Replaced Award that is performance-based, the Replacement Award shall be subject solely to time-based vesting for the remainder of the applicable Performance

(With amendments as of February 14, 2018 )

Period (or such shorter period as determined by the Committee) and the Achieved Performance Criteria in respect of the applicable Performance Period shall be deemed to be the greater of (x) the Median Performance Criteria and (y) the level of achievement of the Performance Criteria applicable to a Performance Period as determined by the Committee no later than the date of the Change in Control, taking in account performance through the latest date preceding the Change in Control as to which performance can, as a practical matter, be determined (but no later than the end of the Performance Period)), and (D) its other terms and conditions are not less favorable to the Participant than the terms and conditions of the Replaced Award (including the provisions that would apply in the event of a subsequent Change in Control) as of the date of the Change in Control. Without limiting the generality of the foregoing, a Replacement Award may take the form of a continuation of the applicable Replaced Award if the requirements of the preceding sentence are satisfied. If a Replacement Award is granted, the Replaced Award shall not immediately vest upon the Change in Control giving rise to the replacement. The determination whether the conditions of this Section 8.5.2(a) are satisfied shall be made by the Committee, as constituted immediately before the Change in Control, in its sole discretion. All PSUs that become Vested PSUs pursuant to this Section 8.5.2(a) shall be paid in accordance with Sections 8.5.1(b) or 8.5.1(c), as applicable.

Notwithstanding any other provision of this Plan to the contrary, upon the Participant’s Termination of Employment by the Corporation or an Affiliate, as applicable, without CIC Cause, or by the Participant for Good Reason, within the Specified Period following a Change in Control, all Replacement Awards held by such Participant shall become Vested PSUs immediately prior to the time of such Termination of Employment, and shall be paid as soon as practicable, and in any event within 30 days, following such Termination of Employment; provided that if the Replacement Award is a Section 409A Amount, and the Change in Control is not a 409A Change in Control, then such Replacement Award shall in all events be paid during the calendar year or years in which it would have been paid had there been no Change in Control. For clarity, in this Section 8.5.2(b), the defined term “Vested PSUs” shall be deemed to apply, mutatis mutandis, to Replacement Awards that are not a continuation of Replaced Awards.

CURRENCY

Currency. Except where expressly provided otherwise, all references in the Plan to currency refer to lawful Canadian currency.

SHAREHOLDER RIGHTS

No Rights to Shares. PSUs are not Shares and neither the grant of PSUs nor the fact that Shares may be acquired by, or provided from, a Trust Fund or otherwise in satisfaction of Vested PSUs will entitle a Participant to any shareholder rights, including, without limitation, voting rights, dividend entitlement or rights on liquidation.

ADMINISTRATION

Committee. Unless otherwise determined by the Board, or as specified in Section 11.6, the Plan shall be administered by the Committee.

Compliance with Laws and Policies. The Corporation’s issuance of any PSUs and its obligation to make any payments or discretion to provide any Shares hereunder is subject to compliance with Applicable Law. Each Participant shall acknowledge and agree (and shall be conclusively deemed to have so acknowledged and agreed by participating in the Plan) that the Participant will, at all times, act in strict compliance with Applicable Law and all other laws and any policies of the Corporation applicable to the Participant in connection with the Plan including, without limitation, furnishing to the Corporation all information and undertakings as may be required to permit compliance with Applicable Law. Such laws, regulations, rules and policies shall include, without limitation, those governing “insiders” or “reporting issuers” as those terms are construed for the purposes of applicable securities laws, regulations and rules.

Delegation. The Committee may also delegate to any director, officer or employee of the Corporation such duties and powers relating to the Plan or in respect of an applicable Grant Agreement as it may see fit.

Withholdings. Notwithstanding any other provision in this Plan, to ensure that the Corporation, an Affiliate or a Trust Fund, as applicable, will be able to comply with the applicable provisions of any federal, provincial, state or local law relating to the withholding of tax or other required deductions, including on the amount, if any, includable in the income of a Participant, the Corporation, or an Affiliate may withhold or cause to be withheld from any amount payable to a Participant, either under this Plan, or otherwise, such amount, or may require the sale of such number of Shares by the Trustee, as may be necessary to permit the Corporation, the Affiliate or a Trust Fund, as applicable, to so comply.

No Additional Rights. Neither designation of an employee as a Participant nor the grant of any PSUs to any Participant at any time entitles any person to the grant, or any additional grant, as the case may be, of any PSUs under the Plan.

Amendment, Termination. The Plan may be amended or terminated at any time by the Board in whole or in part. No amendment of the Plan shall, without the consent of the Participants affected by the amendment, or unless required by Applicable Law, adversely affect the rights accrued to such Participants with respect to PSUs granted prior to the date of the amendment. Notwithstanding any provision in the Plan to the contrary, the Plan may be amended to prevent any adverse tax results under Section 409A of the Code.

Administration Costs. The Corporation will be responsible for all costs relating to the administration of the Plan. For greater certainty and unless otherwise determined by the Committee, a Participant shall be responsible for brokerage fees and other administration or transaction costs relating to the transfer, sale or other disposition of Shares on behalf of the Participant that have been previously distributed to or provided to the Participant pursuant to the Plan.

(With amendments as of February 14, 2018 )

Section 409A.

Section 409A Amounts. To the extent applicable to any Section 409A Amount, it is intended that the Plan and any Grant Agreement or other agreement that amends or otherwise affects such Section 409A Amount will comply with Section 409A of the Code and any regulations and guidance issued thereunder, and the Plan and any such Grant Agreement or other agreement shall be interpreted accordingly. The provisions of this Section 11.8 shall apply to any Section 409A Amount notwithstanding anything in the Plan or a Grant Agreement to the contrary. In no event shall a Section 409A Amount be distributed at a time or pursuant to an event that is not specified in Section 409A(a)(2) of the Code.

Retirement or Termination of Employment. The Plan does not provide for payment to occur upon (or on a specified date or within a specified period following) a Termination of Employment or Retirement; however, to the extent any Grant Agreement or other agreement provides that any Section 409A Amount is to be distributed upon (or on a specified date or within a specified period following) the date of a U.S. Participant’s Termination of Employment or Retirement, such U.S. Participant shall be deemed to have experienced a Termination of Employment or Retirement when (and only when) a separation from service (within the meaning of Treasury Regulation Section 1.409A-1(h)) has occurred.

Specified Employees. If a U.S. Participant is a “specified employee” for purposes of Section 409A of the Code, no payment, distribution or other benefit provided pursuant to a Section 409A Amount that is required to be delayed to comply with Section 409A(a)(2)(B)(i) of the Code shall be provided before the date that is six months after the date of such separation from service (or, if earlier than the end of such six-month period, the date of death of the Participant). Any payment, distribution or other benefit that is delayed pursuant to the prior sentence shall be paid on the first Business Day following the six-month anniversary of the Participant’s separation from service or date of death, as the case may be.

Time of Payment. In no event shall a Participant be entitled to designate the taxable year in which any Section 409A Amount is to be paid. Except with respect to payments following a Change in Control pursuant to Section 8.5.3, Shares or cash to be paid in respect of any Section 409A Amount pursuant to Vested PSUs shall in all events be paid within the calendar year in which the applicable Vesting Date set forth in the applicable Grant Agreement(s) occurs, which for purposes of Section 409A Amounts shall always be defined as occurring within a single calendar year. Payments with respect to Dividend Equivalent PSUs shall be paid at the same time as the PSU to which such Dividend Equivalent PSU relates.

No Acceleration of Payments. In no event shall a change in a Performance Period, a waiver, amendment, exercise of discretion to adjust the Eligible PSU Amount under Section 7.4, or other modification

Performance Share Unit Plan for Employees

of Encana Corporation

(With amendments as of February 14, 2018 )

of any terms or conditions of a PSU or any determination by the Committee or the Board, as applicable in each case, that occurs after the Grant Date cause any Section 409A amount to be paid in a calendar year that is different than the calendar year in which payment would have occurred but for such change to the Performance Period, waiver, amendment, modification, exercise of discretion, or determination.

Trusts. Notwithstanding Section 6.1 hereof, no funds with respect to any Section 409A Amount shall be set aside in a trust located outside the United States or in any other trust or arrangement described under Section 409A(b)(1) of the Code.

ASSIGNMENT

Assignment. The assignment or transfer of the PSUs, or any other benefits under this Plan, shall not be permitted other than by operation of law.
