Severance Agreement, dated March 2, 2010, between Registrant and Tana K. Cashion

Exhibit 10.56

SEVERANCE AGREEMENT

This Severance Agreement (this "Agreement") is effective March 2, 2010 (the "Effective Date") by and between Devon Energy Corporation (the "Company") and Tana Kole Cashion (the "Employee").

WHEREAS, the parties desire to enter into this Agreement relating to the Company’s employment of the Employee.

NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:

1.Term of Agreement.  This Agreement shall not have any specific duration and shall continue in full force and effect unless and until (a) the Employee's employment is terminated by either party in accordance with Section 3, and (b) all obligations and liabilities of the parties arising in connection with such termination or otherwise accruing under this Agreement have been fully satisfied, Notwithstanding any contrary provision in this Agreement, nothing in this Agreement constitutes a guarantee of continued employment but instead provides for certain rights and benefits during the Employee’s employment with the Company and if such employment terminates.

2.Rights and Benefits.  Beginning on a Change in Control and continuing at all times thereafter, the Company shall not modify the requirements for eligibility for coverage or the benefits under the Retiree Medical Benefit Plan to adversely affect the Employee’s right to coverage or benefits for the Employee and the Employee’s dependents, if applicable.

3.Termination of Employment; Suspensions; Change in Control.

(a)Termination Upon Death.  The Employee’s employment with the Company shall terminate immediately upon the Employee’s death.

(b)Reassignment of Duties and Termination Due to the Employee Becoming Disabled.

(i)Reassignment.  Whether or not the Employee is Disabled, the Company may reassign his or her duties during any time he or she has become physically or mentally incapable of performing his or her essential job functions with or without reasonable accommodation or job protection as required by law and no such reassignment shall be deemed Good Reason for the Employee to terminate his or her employment under Section 3(d).

(ii)Termination.  If the Employee becomes Disabled, then the Company may give the Employee written notice of its intent to terminate his or her employment, in which case such employment shall terminate effective on the thirtieth (30th) day after receipt of such notice as long as the Employee has not been medically released and returned to full-time duty before such thirtieth (30th) day.

(c)Termination by the Company; Cause.  The Company may terminate the Employee’s employment with the Company at any time whether with or without Cause.

(d)Termination by the Employee; Good Reason.  The Employee may terminate his or her employment with the Company at any time whether with or without Good Reason.  If the Employee believes Good Reason exists for terminating his or her employment, then he or she shall give the Company written notice of the acts or omissions constituting Good Reason within thirty (30) days after learning of such acts or omissions constituting Good Reason (the "Good Reason Notice").  No termination of employment for Good Reason shall be effective unless (i) within thirty (30) days after receiving the Good Reason Notice, the Company fails to either cure such acts or omissions or notify the Employee of the

intended method of cure, and (ii) the Employee delivers a Notice of Termination to the Company and subsequently resigns within thirty (30) days after the Company’s deadline in Section 3(d)(i) expires.   Notwithstanding the previous sentence and at the Company’s request, the Employee shall provide services consistent with his or her then-current authority, duties, and responsibilities for up to ninety (90) days after having provided the Good Reason Notice to the Company.

(e)Paid Suspensions.  Notwithstanding any contrary provision in this Agreement, the Company may suspend the Employee with pay for up to thirty (30) days pending an investigation authorized by the Company or the Board, or pursued by, or at the request of, a governmental authority to determine whether the Employee has engaged in acts or omissions constituting Cause.  Any such paid suspension shall not constitute Good Reason for the Employee to terminate his or her employment under Section 3(d).  The Employee shall cooperate with the Company in connection with any such investigation.  If the Employee’s employment is subsequently terminated for Cause in connection with such investigation, then the Employee shall repay any amounts paid by the Company to the Employee during such paid suspension.

(f)Effect of a Change in Control on Timing of Termination Date.  If the Company terminates the Employee’s employment other than for Cause or the Employee becoming Disabled and a Change in Control occurs following the Termination Date, then such Change in Control shall be deemed to have occurred immediately prior to the Termination Date if either (i) the Termination Date occurs following the execution of an agreement that provides for a transaction or transactions that, if consummated, constitutes such Change in Control, or (ii) the Employee reasonably demonstrates that such termination was either (A) requested by a third party who had indicated an intention or taken steps reasonably calculated to effect the Change in Control or who effectuates such Change in Control, or (B) was otherwise in connection with, or in anticipation of, such Change in Control.

(g)Notice of Termination.  Any termination of the Employee’s employment by the Company or by the Employee shall be effective only when communicated by a Notice of Termination given to the other party in accordance with Section 15(d).  In the event of a termination by the Employee for Good Reason, a Notice of Termination shall be effective only if given within the time limit established by Section 3(d).

(h)Effect of Termination and Duties Upon Termination.  If, on the Termination Date, the Employee is a member of the board of directors (or any similar governing body) or an officer of the Company or any Affiliate, or holds any other position with the Company or an Affiliate, then the Employee shall resign and be deemed to have resigned from all such positions as of the Termination Date.  Between the date a Notice of Termination is delivered and the Termination Date, the Employee shall continue to perform his or her regular job duties and such services for the Company as are necessary and appropriate for a smooth transition to the Employee’s replacement, if any.  Notwithstanding the foregoing sentence, the Company may relieve the Employee from further duties after receiving a Notice of Termination; provided, however, that prior to the Termination Date, the Employee shall continue to be treated as a Company employee for other purposes and the Employee’s rights to compensation or benefits shall not be reduced by reason of the relief.  Upon the Termination Date, the Employee shall return to the Company any keys, credit cards, passes, confidential documents or material, or other property belonging to the Company, and all writings, files, records, correspondence, notebooks, notes, and other documents and things (including any copies thereof) containing any Confidential Information.

4.Obligations of the Company Upon Termination.

(a)Accrued Obligations.  Upon any termination of the Employee’s employment for any reason, the Company shall pay the Employee (i) his or her accrued Annual Base Salary and accrued, unused vacation through the Termination Date in a lump sum in cash within thirty (30) days after the Termination Date, and (ii) if the Employee is actively employed during the entire year upon which such Annual Bonus

2

is based before the Termination Date, the Annual Bonus at the same time as such bonuses are paid to similarly situated employees of the Company but in no event later than two and one-half (2 ½) months after the end of the taxable year in which any substantial risk of forfeiture with respect to such bonus lapses (the payments in (i) and (ii) shall be referred to as the "Accrued Obligations").

(b)Good Reason; Other Than for Cause, Death, or Becoming Disabled.  If (x) the Company terminates the Employee’s employment other than for Cause, the Employee’s death, or the Employee becoming Disabled, or (y) the Employee terminates his or her employment for Good Reason, then the Company shall, in addition to the payment of the Accrued Obligations, have the following obligations to the Employee:

(i)the Company shall pay the Employee within thirty (30) days after the Termination Date

(A)a lump sum in cash equal to two (2) times the sum of:

(1)the greater of (x) the Employee’s then-current Annual Base Salary, or (y) the Employee’s Annual Base Salary at any time during the two (2) years before the Termination Date; and

(2)the highest Annual Bonus received by the Employee within three (3) years before the Termination Date (or, if termination occurs during the CIC Period, the greater of (x) the highest Annual Bonus received by the Employee within three (3) years before the Termination Date, and (y) the highest Annual Bonus received by the Employee within three (3) years before the Change in Control); provided, however, if the Employee’s employment began in the same calendar year as the termination of such employment, then the Annual Bonus amount used for calculating the lump sum payment due shall be determined by the Compensation Committee in its discretion; and

(B)any applicable Prorated Annual Bonus; and

(ii)the Company shall pay, or reimburse the Employee, for a reasonable amount of outplacement services from a mutually agreeable service provider for twelve (12) months following the Termination Date.  The amount of such outplacement services shall be commensurate with the Employee’s title and position with the Company and other employees similarly situated in other companies within the Company’s peer industry group.  Any reimbursement of such expenses shall be made by December 31 of the Employee’s taxable year following the year the expenses were incurred; and

(iii)if the Termination Date occurs during the CIC Period, then

(A)the Employee shall be deemed, for purposes of the Retiree Medical Benefit Plan, (i) to have earned two (2) years of service in addition to the Employee’s actual service at the Termination Date, and (ii) to be two (2) years older than his or her actual age on the Termination Date; provided, however, that the additional deemed service and age shall not be construed to reduce the Employee’s right to benefits under the Retiree Medical Benefit Plan that may otherwise be reduced by reason of such additional service or age.  This subparagraph (A) shall not limit the ability of the Company or an Affiliate to modify the Retiree Medical Benefit Plan for all participants who are similarly situated as the Employee, subject to the restrictions imposed by the plan;

(B)the Company shall provide the Employee (and his or her dependents, if applicable) for the period allowed under Section 4980B of the Code, with the same level of health and dental insurance benefits upon substantially similar terms and conditions (including contributions required by the Employee for such benefits) as existed immediately before the Termination Date (or, if more favorable to the Employee, as such benefits and terms and conditions existed immediately before the

3

Change in Control, if applicable); provided, however, if the Employee is not eligible to continue participating in the Company plans providing such benefits (including the Retiree Medical Benefit Plan), then the Company shall otherwise provide such benefits on the same after-tax basis as if continued participation had been permitted.  The Company’s obligations under this subparagraph (B) shall apply against its coverage obligations under COBRA.  Notwithstanding the foregoing, if the Employee becomes eligible to receive health and dental insurance benefits through subsequent employment, then the Employee shall ensure that a coordination of benefits occurs so that the medical and dental plan of the Employee’s new employer shall be responsible for such medical and dental benefits that are available under the new employer’s plans before any medical and dental benefits are provided pursuant to this subparagraph (B).  This subparagraph (B) shall not limit the ability of the Company or an Affiliate to modify the terms of the Retiree Medical Benefit Plan for all participants who are similarly situated as the Employee, subject to the restrictions imposed by the plan; and

(C)the Company shall provide, for two (2) years following the Termination Date, the Employee with the same level of life insurance benefits upon substantially similar terms and conditions (including contributions required by the Employee for such benefits) as existed immediately before the Termination Date (or, if more favorable to the Employee, as such benefits and terms and conditions existed immediately before the Change in Control); provided, however, that, if the Employee is not eligible to continue participating in the Company plans providing such life insurance benefits, then the Company shall otherwise provide such benefits on the same after-tax death benefit basis as if continued participation had been permitted; and

(D)the Company shall pay the Employee, within thirty (30) days after the Termination Date, an amount equal to six (6) times the monthly COBRA premium that applies to the Employee (and his or her dependents if such dependents are then covered by the Company’s medical plans on the Termination Date).

(c)Death or Disabled.  If the Employee’s employment terminates due to death or because he or she is Disabled, then this Agreement shall terminate without further obligations to the Employee or his or her legal representatives, as applicable, under this Agreement, other than the obligation to pay, within thirty (30) days after the Termination Date, (i) the Accrued Obligations, and (ii) any applicable Prorated Annual Bonus.

(d)Cause; Other than for Good Reason.  If the Employee’s employment is terminated for Cause or the Employee terminates his or her employment without Good Reason, then this Agreement shall terminate without further obligations to the Employee under this Agreement other than for payment of the Accrued Obligations.

(e)Application of Section 409A of the Code.  Notwithstanding the above paragraphs of this Section 4, if the Company determines that (i) the Employee is a "specified employee" within the meaning of Section 409A of the Code ("Section 409A") as of the date of his or her "separation from service" as defined by Section 409A ("Separation from Service"), and (ii) any amount of any payment to be made under this Section 4 is subject to Section 409A, then such amount shall not be paid to the Employee until six (6) months after the date of his or her Separation from Service (or, if earlier, the date of his or her death).  In such case, the portion of the payment so delayed shall be paid in a single lump sum in cash on the first (1st) day of the seventh (7th) month following the Employee’s Separation from Service (or, if earlier, upon his or her death).

(f)General Release.  The Company’s obligation to make the payments described under Section 4(b) shall be conditioned on the Employee signing and not revoking the general form of release attached as Exhibit "B" or such other form acceptable to the Company within the time periods provided in such release.  The Company shall not be required to make any payment under Section 4(b) until the period for the Employee to revoke the release has expired.

4

5.Non-Exclusivity of Rights.  Except as specifically provided in Sections 4(b)(iii)(A) and (B), nothing in this Agreement shall prevent or limit the Employee’s right to participate in any plan, program, policy, or practice provided by the Company or any Affiliate and for which the Employee may qualify, nor shall anything in this Agreement limit or otherwise affect such rights as the Employee may have under any other contract or agreement with the Company or any Affiliate.  Amounts that are vested benefits or that the Employee is otherwise entitled to receive under any plan, policy, practice, or program of, or any contract or agreement with, the Company or any Affiliate at or after the Termination Date shall be payable in accordance with such plan, policy, practice, program, contract, or agreement, except as explicitly modified by this Agreement, provided, however, that the Employee shall not be eligible for severance benefits under any other severance program, policy, practice, or plan of the Company or any Affiliate providing benefits upon involuntary termination of employment.

6.Full Settlement.  The Company’s payment and other obligations under this Agreement shall not be affected by any set-off, counterclaim, recoupment, defense, or other claim, right, or action against the Employee or others.  The Employee shall have no obligation to seek employment or otherwise mitigate his or her damages under this Agreement and amounts payable to the Employee under this Agreement shall not be reduced whether or not the Employee obtains other employment, except as provided in Section 4(b)(iii) of this Agreement.

7.Certain Additional Payments by the Company.

(a)Gross-Up Payment.  Notwithstanding any contrary provision of this Agreement and except as provided below, if any payment, benefit, or distribution by the Company, any Affiliate, or trusts established by the Company or any Affiliate for the benefit of its employees, to or for the benefit of the Employee (whether pursuant to this Agreement or otherwise but determined without regard to any additional payments required under this Section 7) (each, a "Payment") is determined to be subject to excise tax imposed by the Code, including Section 4999 of the Code, or any interest or penalties are incurred by the Employee with respect to such an excise tax (such excise tax and any such interest and penalties shall referred to as the "Excise Tax"), then the Employee shall be entitled to receive an additional payment (a "Gross-Up Payment") in an amount such that, after payment by the Employee of all taxes (including any applicable interest or penalties) and Excise Tax imposed upon or related to the Gross-Up Payment, the Employee retains a Gross-Up Payment amount equal to the Excise Tax imposed upon the Payments.

(b)Determinations and Tax Notice.  Subject to Section 7(c), all determinations required under this Section 7, including whether and when a Gross-Up Payment is required and its amount, shall be made by a nationally recognized certified public accounting firm designated and paid by the Company (the "Accounting Firm"), which shall provide its analysis and detailed supporting calculations to both the Company and the Employee within fifteen (15) business days after the Employee delivers to the Company any written notice of any claim by the Internal Revenue Service that may require the Company’s Gross-Up Payment (the "Tax Notice").  The Company shall pay any Gross-Up Payment due under this Section 7 to the Employee within five (5) days after receiving the Accounting Firm’s determination but in no event later than December 31 of the year next following the taxable year in which the Employee received the Payment.  If the Accounting Firm determines that no Excise Tax is payable by the Employee, then it shall furnish the Employee with an opinion supporting the determination not to report an Excise Tax on the Employee’s federal income tax return.  Any determination by the Accounting Firm shall be binding upon the parties.  Due to the uncertainty of the application of Section 4999 of the Code when the initial determination is made by the Accounting Firm, it is possible that Gross-Up Payments that will not have been made by the Company should have been made ("Underpayment"), consistent with the calculations required under this Section 7.  If the Company exhausts its remedies pursuant to Section 7(c) and the Employee thereafter is required to pay any Excise Tax, then the Accounting Firm shall determine the amount of the Underpayment that has occurred, and any such Underpayment shall be promptly paid by the Company to or for the benefit of the Employee but in no event later than the December 31 of the year next following the taxable year in which the Employee received the Payment.

5

(c)Contests.  The Tax Notice shall be given as soon as practicable but no later than ten (10) business days after the Employee receives written notice of such claim describing the nature of such claim and indicating the due date for such claim.  The Employee shall not pay such claim until thirty (30) days after delivering the Tax Notice to the Company (or such shorter period imposed by the Internal Revenue Service).  If the Company notifies the Employee in writing before the expiration of such period that it desires to contest such claim, then the Employee shall:

(i)provide any information reasonably requested by the Company relating to such claim;

(ii)contest such claim as the Company shall reasonably request in writing, including, without limitation, accepting legal representation reasonably selected by the Company;

(iii)cooperate with the Company in good faith to effectively contest such claim; and

(iv)permit the Company to participate in any proceedings relating to such claim.

The Company (x) shall pay all costs and expenses (including additional interest and penalties) related to such contest and shall indemnify and hold the Employee harmless, on an after-tax basis, for any Excise Tax or income tax (including interest and penalties) imposed as a result of such representation and payment of costs and expenses, (y) shall control all proceedings taken in connection with such contest and, at its sole option, may pursue or forgo any and all administrative appeals, proceedings, hearings, and conferences with the taxing authority in respect of such claim, and (z) may, at its sole option, either direct the Employee to pay the tax claimed and sue for a refund or contest the claim in any permissible manner, in which case, the Employee shall administratively and judicially prosecute such contest to a determination as the Company shall determine; provided, however, that the Company’s control of the contest shall be limited to issues with respect to which a Gross-Up Payment would be payable under this Agreement and the Employee shall be entitled to settle or contest, as the case may be, any other issue raised by the Internal Revenue Service or any other taxing authority.  If the Company directs the Employee to pay such claim and sue for a refund, then the Company shall, to the extent permitted by law, advance the amount of such payment to the Employee, on an interest-free basis, and shall indemnify and hold the Employee harmless, on an after-tax basis, from any Excise Tax or income tax (including interest or penalties) imposed with respect to such advance or with respect to any imputed income with respect to such advance.  The Company shall make any payment in reimbursement of costs and expenses, Excise Tax, income tax, or other amounts due the Employee under this Section 7(c) no later than December 31 of the year following the year in which (x) the taxes that are the subject of the audit are remitted to the taxing authority, or (y) there is a final and non-appealable settlement or other resolution of the litigation.

(d) Refunds.  If, after receiving an advance from the Company pursuant to Section 7(c), the Employee becomes entitled to receive any refund with respect to such claim, the Employee shall promptly pay the Company the amount of such refund (together with any interest paid or credited after applicable taxes).  If, after receiving an advance from the Company pursuant to Section 7(c), a determination is made that the Employee shall not be entitled to any refund with respect to such claim and the Company does not notify the Employee in writing of its intent to contest such denial of refund before the expiration of thirty (30) days after such determination, such advance shall be forgiven and shall not be required to be repaid and the amount of such advance shall offset the amount of the Gross-Up Payment required to be paid.

8.Confidential Information and Non-Solicitation.

(a)Confidential Information.  Given his or her position and employment with the Company, the Employee acknowledges that he or she will be using, acquiring, and adding to Confidential Information of a special and unique nature and value to the Company and its strategic plan and financial operations.  The Employee further acknowledges that all Confidential Information belongs exclusively to the Company,

6

is material and proprietary, and is critical to the Company’s success.  Accordingly, the Employee shall use Confidential Information only to the Company’s benefit and shall not at any time during or after his or her employment with the Company directly or indirectly disclose any Confidential Information to any person or use any Confidential Information for the Employee’s own benefit, for the benefit of others, or to the Company’s detriment.

(b)Legally Required Disclosure.  If any court or agency requests the Employee to disclose Confidential Information, then the Employee shall promptly notify the Company and take reasonable steps to prevent such disclosure until the Company receives such notice and has an opportunity to respond to such court or agency.  If the Employee obtains information that may be subject to the attorney-client privilege of the Company or any Affiliate, then the Employee shall take reasonable steps to maintain the confidentiality of such information and to preserve such privilege.

(c)Exceptions.  Confidential Information shall not include knowledge that was acquired during the course of the Employee’s employment under this Agreement that is generally known to persons of the Employee’s experience in other companies in the same industry.

(d)Legal Proceedings.  This Section 8 shall not unreasonably restrict the Employee’s ability to disclose Confidential Information in any legal proceeding involving any claim for breach or enforcement of this Agreement.  If the parties dispute whether information may be disclosed in accordance with this Section 8(d), then the matter shall be considered an Employment Matter and decided in accordance with Section 10.

(e)Other Obligations.  This Agreement supplements, rather than supplants, the Employee’s obligations under any Company policy relating to confidential information and any agreement of the Employee relating to confidentiality, inventions, copyrightable material, business and/or technical information, trade secrets, solicitation of employees, interference with business relationships, competition, and other similar matters that protect the business and operations of the Company or its Affiliates.

(f)Non-Solicitation.  During his or her employment with the Company and for twenty four (24) months following the Termination Date, regardless of the reason for such termination, the Employee shall not directly or indirectly hire, employ, solicit for employment, attempt to solicit for employment, or communicate with about changing employment, any person who was an employee of the Company or its Affiliate within six (6) months of such hiring, employing, soliciting, or communicating (the "Non-Solicitation Obligation"); provided, however, that the Non-Solicitation Obligation shall be modified as follows:

(i)the Termination Date occurs during the CIC Period, then the Non-Solicitation Obligation shall expire on the Termination Date; and

(ii)if the Employee terminates his or her employment with the Company without Good Reason, then the Non-Solicitation Obligation shall expire twelve (12) months following the Termination Date.

(g)Remedies.  The Employee acknowledges and agrees that the Company will have no adequate remedy at law and could be irreparably harmed if the Employee breaches or threatens to breach his or her obligations under this Section 8.  The Company shall be entitled to equitable and/or injunctive relief to prevent any such breach or threatened breach and to specific performance in addition to any other available legal or equitable remedies.  The Employee shall not, in any equity proceeding relating to the enforcement of this Section 8, raise the defense that the Company has an adequate remedy at law.

(h)Survival.  The Employee’s obligations under this Section 8 shall survive any termination of the Employee’s employment or of this Agreement.

7

9.Assignment; Successors.

(a)Assignment.  The Company’s rights and obligations under this Agreement may not be assigned to any entity other than an Affiliate without the Employee’s consent.  The Employee’s duties, responsibilities, authorities, compensation, and benefits are personal to the Employee and may not be assigned to any person or entity without written consent from the Company other than by will or the laws of descent and distribution.  This Agreement shall inure to the benefit of and be enforceable by the Employee’s legal representatives.

(b)Successors and Assigns.  This Agreement shall inure to the benefit of and be binding upon the Company and its successors and assigns.

(c)Assumption.  The Company shall require any successor or assignee (whether direct or indirect, by purchase, merger, consolidation, or otherwise) to all or substantially all of the business and/or assets of the Company to assume expressly and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place.

10.Dispute Resolution and Guarantees of Payment.

(a)Mandatory Arbitration.  Subject to Section 10(b), any Employment Matter shall be finally settled by arbitration in Oklahoma City, Oklahoma administered by the AAA under its Employment Arbitration Rules then in effect; provided, however, that the AAA’s Employment Arbitration Rules shall be modified as follows: (i) each arbitrator shall agree to treat as confidential evidence and other information presented, and (ii) there shall be no authority to award punitive damages or liquidated or indirect damages unless such damages could be awarded by a court of competent jurisdiction.  The decision of the arbitrator(s) shall be enforceable in any court of competent jurisdiction.

(b)Injunctions and Enforcement of Arbitration Awards.  Either party may bring an action or special proceeding in a state or federal court of competent jurisdiction in Oklahoma City, Oklahoma to enforce any arbitration award under Section 10(a).  The Company also may bring such an action or proceeding, in addition to its rights under Section 10(a) and whether or not an arbitration proceeding has been or is ever initiated, to temporarily, preliminarily, or permanently enforce Sections 8 or 11.  The Employee agrees that (i) violating Sections 8 or 11 would damage the Company in ways that cannot be measured or repaired, (ii) the Company shall be entitled to an injunction, restraining order, or other equitable relief restraining any actual or threatened violation of Sections 8 or 11, (iii) the Company shall not be required to post a bond or prove actual damages when seeking such an injunction, restraining order, or other equitable relief, and (iv) remedies at law for such violations would be inadequate.

(c)Waiver of Jury Trial.  To the extent permitted by law, the parties waive any and all rights to a jury trial with respect to any Employment Matter.

(d)Attorney Fees.

(i)If (A) a claim for arbitration or a lawsuit in connection with an Employment Matter (an "Employment Matter Claim") is filed by either of the parties, and (B) the Employee is ultimately successful in respect of one or more material claims or defenses brought, raised or pursued in connection with such Employment Matter Claim, then the Company shall reimburse the Employee for all legal fees and expenses reasonably incurred in connection with such Employment Matter Claim, provided that such legal fees are reasonable and are calculated on an hourly rather than a contingency fee basis, as well as all costs and expenses reasonably incurred in connection with pursuing or defending any such Employment Matter Claim.  Except as provided in Section 10(d)(ii) below, the Company shall make such reimbursement to the Employee as soon as practicable following final resolution of the Employment Matter Claim, but no later than December 31 of the year immediately following the year of such resolution, provided that the

8

Company receives appropriate documentation of such attorneys’ fees, costs, and expenses, which shall be provided by the Employee no later than the later of (x) December 31 of the year in which resolution occurs, or (y) sixty (60) days following the resolution of the Employment Matter Claim.

(ii)If an Employment Matter Claim is filed by either of the parties during the CIC Period, or (B) an Employment Matter Claim has been filed prior to a Change in Control but has not been resolved as of the effective date of a Change in Control, then the Employee may submit his or her request for reimbursement of attorneys’ fees, costs and expenses on a monthly basis during the pendency of such Employment Matter Claim.  Within sixty (60) days following the Company’s receipt of each such monthly request and appropriate documentation supporting such request for reimbursement of attorneys’ fees, costs and expenses, the Company shall reimburse the Employee (or pay directly to the Employee’s attorney) the Employee’s attorneys’ fees, costs and expenses that the Company is obligated, pursuant to Section 10(d)(i) above, to reimburse with respect to such Employment Matter Claim.  In the event the Employee ultimately fails to be successful with respect to at least one of the Employee’s material claims or defenses brought, raised or pursued in connection with such contest or dispute, the Employee shall repay the Company the amount of any such reimbursement received in connection with such dispute in accordance with this Section 10(d) (without interest) as soon as practicable following the final resolution of such matter.

(e)Secondary Liability for Payment.  If any Affiliate is not otherwise obligated to provide benefits to the Employee by this Agreement, then the Company shall take, and cause each such Affiliate (the "Guarantors") to take, such actions as are necessary to cause the Guarantors to jointly and severally guarantee the payment of benefits otherwise due to the Employee under this Agreement if the Company fails to pay such benefit within thirty (30) days of the due date for such payment; provided, however, that no entity organized under the laws of any jurisdiction outside the United States shall have an obligation to enter into such guarantee.  Each of the Guarantors shall be subrogated to the Employee’s rights under this Agreement to the extent of any payments by each such Guarantor to or on account of the Employee under this Section 10(e).

11.Non-Disparagement.  The Employee shall not make any negative or disparaging comments regarding the Company or its Representatives or its or their respective performance, operations, or business practices, or otherwise take any action that could reasonably be expected to adversely affect the Company or such Representatives or their personal or professional reputations.  The Employee may truthfully respond to inquiries by government agencies or to inquiries by any person through a subpoena or other valid judicial process without violating this Section 11, provided that the Employee delivers written notice of such required disclosure to the Company promptly before making such disclosure, unless such notice to the Company is prohibited by applicable law, court order, subpoena, process, or governmental decree.

12.Indemnification and Insurance.

(a)Indemnity.  The Company shall, to the maximum extent permitted by law, defend, indemnify, and hold harmless the Employee and the Employee’s heirs, estate, executors, and administrators against any costs, losses, claims, suits, proceedings, damages, or liabilities to which they may become subject to arising from, based on, or relating to the Employee’s employment by the Company (and any predecessor of the Company), or the Employee’s service as an officer or member of the board of directors (or any similar governing body) of the Company (or any predecessor of the Company) or any Affiliate, including without limitation reimbursement for any legal or other expenses reasonably incurred by the Employee in connection with investigation and defending against any such costs, losses, claims, suits, proceedings, damages, or liabilities.

(b)Insurance.  The Company shall maintain directors and officers liability insurance in commercially reasonable amounts (as reasonably determined by the Board), and the Employee shall be covered under such insurance to the same extent as other similarly situated employees of the Company; provided, however, that the Company shall not be required to maintain such insurance coverage if the Board

9

determines that it is unavailable at reasonable cost, provided that the Employee is given written notice of any such determination promptly after it is made.

(c)Gross-Up.  If the value of any benefits or payment provided under Section 12(a) is subject to income taxes, then the Company shall make a Gross-up Payment (as described in Section 7(a)) to the Employee, by December 31 of the year next following the Employee’s taxable year in which the income taxes were incurred, such that, after payment of all taxes imposed on or related to such Gross-up Payment, the Employee retains an amount equal to 75% of the federal, state, and local income taxes imposed upon such benefits or payment.

13.Employee to Provide Assistance with Claims.  During his or her employment with the Company and following the termination of such employment, regardless of the reason for such termination, the Employee shall assist the Company in defending any claims that may be made against the Company, and shall assist the Company in prosecuting any claims that may be made by the Company, to the extent that such claims may relate to the Employee’s services for the Company.  The Employee shall promptly inform the Company if he or she learns of any lawsuits involving such claims that may be filed against the Company.  The Company shall reimburse the Employee for all reasonable out-of-pocket expenses associated with such assistance, including travel expenses, incurred and accounted for in accordance with its standard policies and procedures for expense reimbursements and deductibles under Section 162(m) of the Code.  For periods after the Termination Date, the Company shall provide reasonable compensation to the Employee for such assistance at a rate to be determined by the Company in its discretion.  The Employee shall promptly inform the Company if asked to assist in any investigation of the Company that may relate to the Employee’s services for the Company, regardless of whether a lawsuit has then been filed against the Company with respect to such investigation.  For purposes of this Section 13, the term "Company" shall include the Company and its Affiliates.

EXHIBIT B

GENERAL RELEASE

NOTICE

Devon Energy Corporation (the "Company") is an equal opportunity employer.  Various laws prohibit employment discrimination based on sex, race, color, national origin, religion, age, disability, eligibility for covered employee benefits, veteran status, and other legally protected characteristics.  You may also have rights under other federal, state, and/or municipal statutes, orders, or regulations pertaining to labor, employment, and/or employee benefits.  These laws are enforced through the United States Department of Labor (DOL), the Equal Employment Opportunity Commission (EEOC), and various other federal, state, and municipal labor departments, fair employment boards, human rights commissions, similar agencies, and courts.

This General Release is being provided to you in connection with the Severance Agreement previously entered between you and the Company (the "Severance Agreement").  You have at least twenty-one (21) days from the date you receive this General Release, if you want it, to consider whether you wish to sign this General Release and receive the payments and benefits (the "Severance Benefits") available under the Severance Agreement for doing so.  You have at least until the close of business twenty-one (21) days from the date you receive this General Release to make your decision.  You may not, however, sign this General Release until, at the earliest, your last effective date of employment.

BEFORE SIGNING THIS GENERAL RELEASE YOU SHOULD REVIEW IT CAREFULLY.  YOU ALSO HAVE THE RIGHT TO CONSULT WITH AN ATTORNEY OF YOUR CHOICE.

You may revoke this General Release within seven (7) days after you sign it and it shall not become effective or enforceable until that revocation period has expired.  If you do not timely sign and return this General Release, or if you exercise your right to revoke the General Release after signing it, then you will not be eligible to receive the Severance Benefits.  Any revocation must be in writing and must be received by the Company within the seven-day period following your execution of this General Release.

GENERAL RELEASE

In consideration of the Severance Benefits offered to me by the Company under the Severance Agreement, I hereby (i) release and discharge the Company and its predecessors, successors, affiliates, parent, subsidiaries, and partners and each of those entities’ current and former employees, officers, directors, and agents (together, the "Released Parties") from all claims, liabilities, demands, and causes of action, known or unknown, fixed or contingent, that I may have or claim to have against them, including without limit any claims that result from or arise out of my past employment with the Company, the severance of that relationship and/or otherwise, or any contract or agreement with or relating to the Released Parties, and (ii) waive any and all rights I may have with respect to and promise not to file a lawsuit to assert any such claims.

This General Release includes, but is not limited to, claims arising under the Age Discrimination in Employment Act ("ADEA") and any other federal, state, and/or municipal statutes, orders, or regulations pertaining to labor, employment, and/or employee benefits.  This General Release also applies without limitation to any claims or rights I may have growing out of any legal or equitable restrictions on the rights of the Released Parties not to continue an employment relationship with their employees, including any express or implied employment or other contracts, and to any claims I may have against the Released Parties

- 1 -

for fraudulent inducement or misrepresentation, defamation, wrongful termination, or other torts or retaliation claims in connection with workers’ compensation, any legally protected activity, or alleged whistleblower status, or on any other basis whatsoever.

It is specifically agreed, however, that this General Release does not have any effect on any rights or claims under the ADEA I may have against the Company that arise after the date I execute this General Release or on any vested rights I may have under any of the Company’s qualified benefit plans or arrangements as of or after my last day of employment with the Company or on any of the Company’s obligations under the Severance Agreement.

MISCELLANEOUS

By signing this General Release, I shall, and hereby do, resign from any corporate, board, and other offices and positions I may hold with the Company and its affiliates as of the date my employment with the Company terminated.

I agree that (i) none of the Released Parties shall have any obligation to employ or to hire or rehire me, to consider me for hire, or to deal with me in any respect with regard to potential future employment; (ii) I shall not ever apply for or otherwise seek employment with any of the Released Parties at any time in the future; and (iii) my forbearance to seek future employment as just stated shall be construed as being purely contractual and in no way involuntary, discriminatory, or retaliatory.

I have carefully reviewed and fully understand all the provisions of the Severance Agreement and General Release, including the foregoing Notice.  I have not relied on any representation or statement, oral or written, relating to the Severance Agreement or this General Release by the Released Parties that are not set forth in those documents.

The Severance Agreement and this General Release, including the foregoing Notice, set forth the entire agreement between me and the Company with respect to payments and benefits payable to me due to the termination of my employment with the Company, and supersede all prior agreements and understandings, written and oral, between the parties with respect to such subject matters.  I understand that my receipt and retention of the Severance Benefits are contingent not only on my execution and non-revocation of this General Release, but also on my continued compliance with my other obligations under the Severance Agreement.  I acknowledge that the Company has given me at least twenty-one (21) days to consider whether I wish to accept or reject the Severance Benefits I am otherwise eligible to receive under the Severance Agreement in exchange for signing and not revoking this General Release.  I hereby represent and state that I fully understand the effects and consequences of the Severance Agreement and General Release prior to signing those documents.

This General Release and the Company’s obligation to provide the Severance Benefits under the Severance Agreement shall be interpreted and construed to comply with Section 409A of the Internal Revenue Code (the "Code").  The parties agree to cooperate and work together in good faith to take all actions reasonably necessary to effectuate the intent of this paragraph.  Notwithstanding the preceding sentence, I understand and acknowledge that I shall be solely responsible for any risk that the tax treatment of all or part of the Severance Benefits may be affected by Section 409A of the Code and impose significant adverse tax consequences on me, including accelerated taxation, a 20% additional tax, and interest.  Because of the potential tax consequences, I understand that I have the right, and am encouraged by this paragraph, to consult with a tax advisor of my choice before signing this General Release.

This General Release shall be governed by the laws of the State of Oklahoma, without regard to any conflict-of-laws principles, and shall not be modified unless in writing signed by both of the parties.
