Exhibit 3.1

RESOLUTION OF

THE BOARD OF DIRECTORS

OF BANCFIRST CORPORATION

WHEREAS, the Board of Directors has determined that it is advisable and in the best interests of the Company that the Bylaws be amended to provide that the vote required for contested elections of directors be based upon a plurality of the shares voting on the election;

NOW, THEREFORE, BE IT RESOLVED, that Article II, Section 4 of the Company’s Bylaws be amended to read in its entirety as follows:

Section 4. At each meeting of the shareholders, every shareholder having the right to vote shall be entitled to vote in person, or by proxy appointed by an instrument in writing subscribed by such shareholder and bearing a date not more than eleven (11) months prior to the date of exercise of said proxy, unless said instrument provides for a longer period, not to exceed seven (7) years, which instrument shall be filed with the secretary of the corporation at or before the meeting. Unless demanded by a shareholder, proxy or other person entitled to vote at the meeting, no vote need be by ballot, and voting need not be conducted by inspectors. Subject to the provisions of Article III, Section 4, herein, nominees for election as directors must receive a “for” vote of the majority of the shares voting on the election; provided, however, that if, as of the tenth (10th) day preceding the date the corporation first transmits its notice of meeting for such meeting to the stockholders of the corporation, or at any time thereafter, the number of nominees exceeds the number of directors to be elected (a “contested election”), the directors shall be elected by a “for” vote of a plurality of the shares voting on the election. All other proposals shall be decided by a majority vote of the shares outstanding and entitled to vote at such meeting, unless otherwise provided by law.

AND, BE IT RESOLVED, that Article III, Section 4(b) of the Company’s Bylaws be amended to read in its entirety as follows:

(b) In the event an incumbent director, whether one or more, or any nominee standing for election to a vacant seat on the Board of Directors, fails to receive the number of votes required for their election, that individual shall not be elected to the Board of Directors, and shall not serve for the ensuing term.

FURTHER RESOLVED, that the Amended and Restated Bylaws of the Company be revised to include the amended Sections, as presented above.

ARTICLE VI

STOCK ADJUSTMENTS

In the event that the shares of Common Stock, as constituted on the Effective Date of the Plan, shall be changed into or exchanged for a different number or kind of shares of stock or other securities of the Company or of another corporation (whether by reason of merger, consolidation, recapitalization, reclassification, stock split, spin-off, combination of shares or otherwise), or if the number of such shares of Common Stock shall be increased through the payment of a stock dividend, or a dividend on the shares of Common Stock, or if rights or warrants to purchase securities of the Company shall be issued to holders of all outstanding Common Stock, then there shall be substituted for or added to each share available under and subject to the Plan, and each share theretofore appropriated under the Plan, the number and kind of shares of stock or other securities into which each outstanding share of Common Stock shall be so changed or for which each such share shall be exchanged or to which each such share shall be entitled, as the case may be, on a fair and equivalent basis. In the event there shall be any other change in the number or kind of the outstanding shares of Common Stock, or any stock or other securities into which the Common Stock shall have been changed or for which it shall have been exchanged, then if the Committee shall, in its sole discretion, determine that such change equitably requires an adjustment in the shares available under and subject to the Plan, or in any Award, theretofore granted, such adjustments shall be made in accordance with such determination, except that no

adjustment of the number of shares of Common Stock available under the Plan or to which any Award relates that would otherwise be required shall be made unless and until such adjustment either by itself or with other adjustments not previously made would require an increase or decrease of at least 1% in the number of shares of Common Stock available under the Plan or to which any Award relates immediately prior to the making of such adjustment (the “Minimum Adjustment”). Any adjustment representing a change of less than such minimum amount shall be carried forward and made as soon as such adjustment together with other adjustments required by this Article VI and not previously made would result in a Minimum Adjustment. Notwithstanding the foregoing, any adjustment required by this Article VI which otherwise would not result in a Minimum Adjustment shall be made with respect to shares of Common Stock relating to any Award immediately prior to exercise, payment or settlement of such Award. No fractional shares of Common Stock or units of other securities shall be issued pursuant to any such adjustment, and any fractions resulting from any such adjustment shall be eliminated in each case by rounding downward to the nearest whole share.

ARTICLE VII

GENERAL

SECTION 7.1 Amendment or Termination of Plan. The Board may suspend or terminate the Plan at any time. In addition, the Board may, from time to time, amend the Plan in any manner, but may not without shareholder approval adopt any amendment which would (i) increase the aggregate number of shares of Common Stock available under the Plan (except by operation of Article VI), (ii) materially modify the requirements as to eligibility for participation in the Plan, or (iii) materially increase the benefits to Participants provided by the Plan.

SECTION 7.2 Termination of Employment; Termination of Service. The Committee may, in its sole discretion, accelerate the vesting of unvested Awards in the event of termination of employment of any Participant. Unless otherwise accelerated, all unvested Awards shall be forfeited upon termination of employment. In the event an Eligible Director terminates service as a director of the Company, the unvested portion of any Award shall be forfeited unless otherwise accelerated pursuant to the terms of the Eligible Director’s Award Agreement or by the Committee.

SECTION 7.3 Withholding Taxes. Unless otherwise paid by the Participant, the Company, its Subsidiaries or any of its Affiliated Entities shall be entitled to deduct from any Award under the Plan, regardless of the form of such Award, the amount of all applicable income and employment taxes required by law to be withheld with respect to such payment or may require the Participant to pay to it such tax prior to and as a condition of making any payment under the Award. In accordance with any applicable administrative guidelines it establishes, the Committee may allow a Participant to pay the amount of taxes required by law to be withheld from an Award by (i) directing the Company to withhold from any payment of the Award a number of shares of Common Stock having a Fair Market Value equal to the amount of the required withholding taxes or (ii) delivering to the Company previously owned shares of Common Stock having a Fair Market Value equal to the amount of the required withholding taxes. In the event that the number of shares of Common Stock withheld or delivered does not equal the required tax withholding amount then the Company will retain the largest whole number of shares that does not exceed the aggregate tax withholding amount and the Participant shall pay to the Company any remaining balance of the aggregate tax withholding amount not satisfied by the number of shares withheld from or delivered by the Participant.

SECTION 7.4 Change of Control. The Committee may determine whether Awards granted under the Plan to any Eligible Employee or Eligible Director will vest upon the occurrence of a Change of Control Event or will be assumed or exchanged for a replacement award in the surviving entity.

SECTION 7.5 Amendments to Awards. Subject to the limitations of the Plan, the Committee may at any time unilaterally amend the terms of any Award Agreement, whether or not presently exercisable or vested, to the extent it deems appropriate. However, amendments which are adverse to the Participant shall require the Participant’s consent.

SECTION 7.6 Regulatory Approval and Listings. The Company shall use its best efforts to file with the Securities and Exchange Commission as soon as practicable following approval of the Plan by the shareholders of the

Company as provided in Section 1.2, and keep continuously effectively, a Registration Statement on Form S-8 with respect to shares of Common Stock subject to Awards hereunder. Notwithstanding anything contained in this Plan to the contrary, the Company shall have no obligation to issue shares of Common Stock under this Plan prior to:

(a) the obtaining of any approval from, or satisfaction of any waiting period or other condition imposed by, any governmental agency which the Committee shall, in its sole discretion, determine to be necessary or advisable;

(b) the admission of such shares to listing on the stock exchange on which the Common Stock may be listed; and

(c) the completion of any registration or other qualification of such shares under any state or Federal law or ruling of any governmental body which the Committee shall, in its sole discretion, determine to be necessary or advisable.

SECTION 7.7 Right to Continued Employment. Participation in the Plan shall not give any Eligible Employee any right to remain in the employ of the Company, any Subsidiary, or any Affiliated Entity. The Company, any Subsidiary or Affiliated Entity reserves the right to terminate any Eligible Employee at any time. Further, the adoption of this Plan shall not be deemed to give any Eligible Employee or any other individual any right to be selected as a Participant or to be granted an Award.

SECTION 7.8 Reliance on Reports. Each member of the Committee and each member of the Board shall be fully justified in relying or acting in good faith upon any report made by the independent public accountants of the Company and its Subsidiaries and upon any other information furnished in connection with the Plan by any person or persons other than himself or herself. In no event shall any person who is or shall have been a member of the Committee or of the Board be liable for any determination made or other action taken or any omission to act in reliance upon any such report or information or for any action taken, including the furnishing of information, or failure to act, if in good faith.

SECTION 7.9 Construction. Masculine pronouns and other words of masculine gender shall refer to both men and women. The titles and headings of the sections in the Plan are for the convenience of reference only, and in the event of any conflict, the text of the Plan, rather than such titles or headings, shall control.

SECTION 7.10 Governing Law. The Plan shall be governed by and construed in accordance with the laws of the State of Oklahoma except as superseded by applicable Federal law.

SECTION 7.11 Other Laws. The Committee may refuse to issue or transfer any shares of Common Stock or other consideration under an Award if, acting in its sole discretion, it determines that the issuance or transfer of such shares or such other consideration might violate any applicable law or regulation or entitle the Company to recover the same under Section 16(b) of the Exchange Act, and any payment tendered to the Company by a Participant, other holder or beneficiary in connection with the exercise of such Award shall be promptly refunded to the relevant Participant, holder or beneficiary.

SECTION 7.12 No Trust or Fund Created. Neither the Plan nor an Award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between the Company and a Participant or any other person. To the extent that a Participant acquires the right to receive payments from the Company pursuant to an Award, such right shall be no greater than the right of any general unsecured creditor of the Company.

SECTION 7.13 Compliance with Section 409A of the Code.

(a) To the extent applicable, it is intended that this Plan and any grants made hereunder are either exempt from or comply with the provisions of Section 409A of the Code, so that the income inclusion provisions of Section 409A(a)(1) of the Code do not apply to Plan Participants. This Plan and any grants made hereunder will be administered in a manner consistent with this intent. Any reference in this Plan to Section 409A of the Code will also include any regulations or any other formal guidance promulgated with respect to such Section by the U.S. Department of the Treasury or the Internal Revenue Service.

(b) If, at the time of a Participant's separation from service (within the meaning of Section 409A of the Code), (i) the Participant will be a specified employee (within the meaning of Section 409A of the Code and using the identification methodology selected by the Company from time to time) and (ii) the Company makes a good faith determination that an amount payable hereunder constitutes deferred compensation (within the meaning of Section 409A of the Code) the payment of which is required to be delayed pursuant to the six-month delay rule set forth in Section 409A of the Code in order to avoid taxes or penalties under Section 409A of the Code, then the Company will not pay such amount on the otherwise scheduled payment date but will instead pay it, without interest, on the tenth business day of the seventh month after such separation from service (or upon the Participant’s death, if earlier).

(c) Notwithstanding any provision of this Plan and grants hereunder to the contrary, in light of the uncertainty with respect to the proper application of Section 409A of the Code, the Company reserves the right to make amendments to this Plan and grants hereunder as the Company deems necessary or desirable to avoid the imposition of taxes or penalties under Section 409A of the Code. In any case, a Participant will be solely responsible and liable for the satisfaction of all taxes and penalties that may be imposed on a Participant or for a Participant's account in connection with this Plan and grants hereunder (including any taxes and penalties under Section 409A of the Code), and neither the Company nor any of its affiliates will have any obligation to indemnify or otherwise hold a Participant harmless from any or all of such taxes or penalties.

(d) Notwithstanding anything in the Plan and grants hereunder to the contrary, to the extent that any amount or benefit that would constitute non-exempt “deferred compensation” for purposes of Section 409A of the Code would otherwise be payable or distributable, or a different form of payment (e.g., lump sum or installment) would be effected, under the Plan or any Award by reason of the occurrence of a Change in Control Event, or the Participant’s Disability or separation from service, such amount or benefit will not be payable or distributable to the Participant, and/or such different form of payment will not be effected, by reason of such circumstance unless the circumstances giving rise to such Change in Control Event, Disability or separation from service meet any description or definition of “change in control event”, “disability” or “separation from service”, as the case may be, in Section 409A of the Code and applicable regulations (without giving effect to any elective provisions that may be available under such definition). This provision does not prohibit the vesting of any Award upon a Change in Control Event, Disability or separation from service, however defined. If this provision prevents the payment or distribution of any amount or benefit, or the application of a different form of payment of any amount or benefit, such payment or distribution shall be made at the time and in the form that would have applied absent the Change in Control Event, Disability or separation from service, as applicable.

SECTION 7.14 Clawback Provision. Notwithstanding any provision of this Plan and grants hereunder to the contrary, any agreement evidencing an Award under the Plan may also provide for the cancellation or forfeiture of an Award or the forfeiture and repayment to the Company of any shares of Common Stock issued under and/or any other benefit related to an Award (including, for the avoidance of doubt, any cash received in the settlement of an Award), or other provisions intended to have a similar effect, upon such terms and conditions as may be required by the Committee or under Section 10D of the Exchange Act and any applicable rules or regulations promulgated by the Commission or any national securities exchange or national securities association on which the shares of Common Stock may be traded.
