**Item 6. Indemnification of Directors and Officers.** 

The Company is incorporated under the Delaware General Corporation Law (the "DGCL"). Section 145 of the DGCL grants each corporation organized thereunder the power to indemnify any person who is or was a director, officer, employee or agent of a corporation or enterprise against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of being or having been in any such capacity, if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding had no reasonable cause to believe such person's conduct was unlawful, except that with respect to an action or suit brought by or in the right of the corporation such indemnification is limited to expenses (including attorneys' fees) in connection with the defense or settlement of such action or suit. The DGCL provides that Section 145 is not exclusive of other rights to which those seeking indemnification may be entitled

&nbsp;&nbsp;2<br>

------

under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise. The Company's amended and restated bylaws provide for indemnification by the Company of its directors, officers, employees and agents to the fullest extent permitted by the DGCL, subject to limited exceptions.

Section 102(b)(7) of the DGCL permits a corporation to provide in its certificate of incorporation that a director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) for unlawful payments of dividends or unlawful stock repurchases, redemptions or other distributions or (iv) for any transaction from which the director derived an improper personal benefit. The Company's amended and restated certificate of incorporation provides for such limitation of liability.

The Company maintains insurance policies under which coverage is provided (a) to its directors and officers, in their respective capacities as such, against loss arising from a claim made for any actual or alleged wrongful act, and (b) to itself with respect to payments which the Company may make to such officers and directors pursuant to the above indemnification provision or otherwise as a matter of law.

\* Filed herewith.

**Item 9. Undertakings.** 

(a) The undersigned registrant hereby undertakes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post- effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration Statement;

*provided*, *however*, that paragraphs (a)(1)(i) and (a)(1)(ii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Company pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

&nbsp;&nbsp;6<br>

------

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

&nbsp;&nbsp;7<br>

------

**SIGNATURES** 

Pursuant to the requirements of the Securities Act, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the city of Chicago, State of Illinois, on June 3, 2026.

Re: <u>Registration Statement on Form S-8</u>

Ladies and Gentlemen:

We are acting as special counsel to Byline Bancorp, Inc. (the "<u>Company</u>") in connection with the filing by the Company with the Securities and Exchange Commission ("SEC") of a Registration Statement on Form S-8 (the "<u>Registration Statement</u>") relating to the registration under the Securities Act of 1933, as amended (the "<u>Securities Act</u>") of up to an aggregate 1,900,000 shares (the "<u>Shares</u>") of the Company's common stock, par value $0.01 per share (the "<u>Common Stock</u>"), consisting of 1,700,000 Shares that may be offered from time to time under the Byline Bancorp, Inc. 2026 Omnibus Incentive Compensation Plan (the "<u>2026 Omnibus Plan</u>") and 200,000 Shares that may be offered from time to time under the Byline Bancorp, Inc. Employee Stock Purchase Plan (the "<u>ESPP</u>," and together with the 2026 Omnibus Plan, the "<u>Plans</u>").

In connection with our opinion, we have examined originals, or copies, certified or otherwise identified to our satisfaction, of the Registration Statement, the Amended and Restated Certificate of Incorporation of the Company, the Amended and Restated Bylaws of the Company, the Plans and such other corporate records, documents and other papers as we deemed necessary to examine for purposes of this opinion. We have assumed the authenticity, accuracy and completeness of all documents submitted to us as originals, the conformity to authentic original documents of all documents submitted to us as certified, conformed or photostatic copies and the genuineness of all signatures. We have also assumed that the Shares will remain reserved for issuance under the Plans until actually issued thereunder.

Based on the foregoing, it is our opinion that the Shares, when issued by the Company in accordance with the Plans, will be validly issued, fully paid and nonassessable.

The opinion expressed herein is based on the facts in existence and the laws in effect on the date hereof and is limited to the Federal securities laws and the General Corporation Law of the State of Delaware currently in effect. The opinions expressed herein are matters of professional judgment and are not a guarantee of result.

We hereby consent to the use of this opinion in connection with the Registration Statement and to references to our firm therein. In giving our consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the SEC thereunder.

Very truly yours,<br>

Each Designated Person will be indemnified and held harmless by the Company against and from:

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)any loss, cost, liability or expense (including attorneys' fees) that may be imposed upon or incurred by such Designated Person in connection with or resulting from any action, suit or proceeding to which such Designated Person may be a party or in which such Designated Person may be involved by reason of any action taken or omitted to be taken under the Plan or any Award Agreement, in each case, in good faith; and

The foregoing right of indemnification will not be available to a Designated Person to the extent that a court of competent jurisdiction in a final judgment or other final adjudication, in either case, not subject to further appeal, determines that the acts or omissions of such Designated Person giving rise to the indemnification claim resulted from such Designated Person's bad faith, fraud or willful misconduct. The foregoing right of indemnification will not be exclusive of any other rights of indemnification to which Designated Persons may be entitled under Byline's Amended and Restated Bylaws, pursuant to any individual indemnification agreements between such Designated Person and the Company, as a matter of law, or otherwise, or any other power that the Company may have to indemnify such persons or hold them harmless.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.6.1 **<u>Common Stock Subject to the Plan</u>***.* Subject to the other provisions of this <u>Section 1.6</u>, the total number of Shares that may be granted under the Plan will be 1,700,000 (the "**<u>Share Limit</u>**"). Shares of Common Stock subject to awards that are assumed, converted or substituted under the Plan as a result of the Company's acquisition of another company (including by way of merger, combination or similar transaction) will not count against the number of Shares that may be granted under the Plan. Available shares under a stockholder approved plan of an acquired company (as appropriately adjusted to reflect the transaction) may be used for Awards under the Plan and do not reduce the maximum number of Shares available for grant under the Plan, subject to applicable stock exchange requirements. With respect to Awards of stock-settled share appreciation rights, the Share Limit will be reduced by the full number of Shares underlying the exercised portion of such Award (rather than only the Shares actually delivered upon exercise). Notwithstanding anything to the contrary contained herein, the Share Limit shall be reduced by one (1) Share for every Share subject to an award granted under the Byline Bancorp, Inc. 2017 Omnibus Incentive Compensation Plan after April 8, 2026 and prior to the Effective Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.6.2 **<u>Replacement of Shares</u>***.* Shares subject to an Award that is forfeited (including any restricted Shares repurchased by the Company at the same price paid by the Grantee so that such Shares are returned to the Company), expires or is settled for cash (in whole or in part), to the extent of such forfeiture, expiration or cash settlement will be available for future grants of Awards under the Plan and will be added back in the same number of Shares as were deducted in respect of the grant of such Award. The payment of dividend equivalent rights in cash in conjunction with any outstanding Awards will not be counted against the Shares available for issuance under the Plan. Shares tendered by a Grantee or withheld by the Company in payment of the exercise price of a stock option, to satisfy any tax withholding obligation with respect to an Award, or covered by a stock appreciation right (to the extent that it is settled in Shares) will not again be available for Awards.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.6.3 **<u>Adjustments</u>***.* The Committee will:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)adjust the number of Shares, and the type of property or securities, authorized pursuant to <u>Section 1.6.1</u>,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)adjust the number of Shares, and the type of property or securities, set forth in <u>Section 2.3.2</u> that can be issued through Incentive Stock Options; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)adjust any other terms of the Plan and the terms of any outstanding Awards (including, without limitation, the number of Shares covered by each outstanding Award, the type of property or securities to which the Award relates and the exercise or strike price of any Award),

in such manner as the Committee deems appropriate (including, without limitation, by payment of cash or other property or securities) to prevent the enlargement or dilution of rights, as a result of any increase or decrease in the number of issued Shares (or issuance of shares of stock or other property or securities other than Shares) resulting from a recapitalization, stock split, reverse stock split, stock dividend, spinoff, split up, combination, reclassification or exchange of Shares, merger, consolidation, rights offering, separation, reorganization or liquidation or any other change in the corporate structure or Shares, including any extraordinary dividend or extraordinary distribution; <u>provided</u> that no such adjustment may be made if or to the extent that it would cause an outstanding Award to cease to be exempt from, or to fail to comply with, Section 409A.

------

**1.7 Limits on Compensation to Non-Employee Directors**

Aggregate Awards to any one Non-Employee Director in respect of any fiscal year, solely with respect to his or her service as a Director, may not exceed $2,000,000 based on the aggregate value of cash Awards and Fair Market Value of stock-based Awards, in each case, determined as of the date of grant.

**ARTICLE II**

**AWARDS UNDER THE PLAN**

**2.1 Agreements Evidencing Awards**

Each Award granted under the Plan will be evidenced by an Award Agreement that will contain such provisions and conditions as the Committee deems appropriate, including any additional contractual terms, other than the terms of the Award, that the Committee or the Company determines that a Grantee must accept as a condition of receiving an Award. Unless otherwise provided herein, the Committee may grant Awards in tandem with or, subject to <u>Section 3.15</u>, in substitution for or satisfaction of any other Award or Awards granted under the Plan or any award granted under any other plan of the Company. By accepting an Award pursuant to the Plan, a Grantee thereby agrees that the Award will be subject to all of the terms and provisions of the Plan and the applicable Award Agreement.

**2.2 No Rights as a Stockholder**

No Grantee (or other person having rights pursuant to an Award) will have any of the rights of a stockholder of Byline with respect to Shares subject to an Award until the delivery of such Shares. Except as otherwise provided in <u>Section 1.6.3</u> or the terms of the Award, no adjustments will be made for dividends, distributions or other rights (whether ordinary or extraordinary, and whether in cash, Common Stock, other securities or other property) for which the record date is before the date the Certificates for the Shares are delivered, or in the event the Committee elects to use another system, such as book entries by the transfer agent, before the date in which such system evidences the Grantee's ownership of such Shares.

**2.3 Options**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.3.1 **<u>Grant</u>**. Stock options may be granted to eligible recipients in such number and at such times during the term of the Plan as the Committee may determine.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.3.2 **<u>Incentive Stock Options</u>***.* At the time of grant, the Committee will determine:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)whether all or any part of a stock option granted to an eligible Employee will be an Incentive Stock Option; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)the number of Shares subject to such Incentive Stock Option; <u>provided</u>*,* <u>however</u>, that

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)the aggregate Fair Market Value (determined as of the time the option is granted) of the stock with respect to which Incentive Stock Options are exercisable for the first time by an eligible Employee during any fiscal year (under all such plans of Byline and of any Subsidiary or parent corporation of Byline) may not exceed $100,000; and

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)no Incentive Stock Option (other than an Incentive Stock Option that may be assumed or issued by the Company in connection with a transaction to which Section 424(a) of the Code applies) may be granted to a person who is not eligible to receive an Incentive Stock Option under the Code.

The form of any stock option which is entirely or in part an Incentive Stock Option will clearly indicate that such stock option is an Incentive Stock Option or, if applicable, the number of Shares subject to the Incentive Stock Option. No more than 1,700,000 Shares (as adjusted pursuant to the provisions of <u>Section 1.6.3</u>) that can be delivered under the Plan may be issued through Incentive Stock Options.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.3.3 **<u>Exercise Price</u>***.* The exercise price per Share with respect to each stock option will be determined by the Committee but, except as otherwise permitted by <u>Section 1.6.3</u>, may never be less than the Fair Market Value of a share of Common Stock (or, in the case of an Incentive Stock Option granted to a Ten Percent Stockholder, 110% of the Fair Market Value). Unless otherwise noted in the Award Agreement, the Fair Market Value of the Common Stock will be its Fair Market Value on the date of grant of the Award of stock options.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.3.4 **<u>Term of Stock Option</u>***.* In no event will any stock option be exercisable after the expiration of ten (10) years (or, in the case of an Incentive Stock Option granted to a Ten Percent Stockholder, five (5) years) from the date on which the stock option is granted.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.3.5 **<u>Vesting and Exercise of Stock Option and Payment for Shares</u>***.* A stock option may **v**est and be exercised at such time or times and subject to such terms and conditions as will be determined by the Committee at the time the stock option is granted and set forth in the Award Agreement. Subject to any limitations in the applicable Award Agreement, any Shares not acquired pursuant to the exercise of a stock option on the applicable vesting date may be acquired thereafter at any time before the final expiration of the stock option.

To exercise a stock option, the Grantee must give written notice to the Company specifying the number of Shares to be acquired and accompanied by payment of the full purchase price therefor in cash or by certified or official bank check or in another form as determined by the Company, which may include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)personal check,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Shares, based on the Fair Market Value as of the exercise date,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)any other form of consideration approved by the Company and permitted by applicable law, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)any combination of the foregoing.

The Committee may also make arrangements for the cashless exercise of a stock option. Any person exercising a stock option will make such representations and agreements and furnish such information as the Committee may, in its sole discretion, deem necessary or desirable to effect or assure compliance by the Company on terms acceptable to the Company with the provisions of the Securities Act, the Exchange Act and any other applicable legal requirements. The Committee may, in its sole discretion, also take whatever additional actions it deems appropriate to effect such compliance

including, without limitation, placing legends on share certificates and issuing stop-transfer notices to agents and registrars.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.3.6 **<u>No Repricing</u>***.* Except as otherwise permitted by <u>Section 1.6.3</u>, reducing the exercise price of stock options issued and outstanding under the Plan, including through amendment, cancellation in exchange for the grant of a substitute Award or repurchase for cash or other consideration (in each case that has the effect of reducing the exercise price), will require approval of Byline's stockholders. Byline will not grant any stock options with automatic reload features.

**2.4 Stock Appreciation Rights**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.4.1 **<u>Grant</u>***.* Stock appreciation rights may be granted to eligible recipients in such number and at such times during the term of the Plan as the Committee may determine.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.4.2 **<u>Exercise Price</u>***.* The exercise price per Share with respect to each stock appreciation right will be determined by the Committee but, except as otherwise permitted by <u>Section 1.6.3</u>, may never be less than the Fair Market Value of the Common Stock. Unless otherwise noted in the Award Agreement, the Fair Market Value of the Common Stock will be its Fair Market Value on the date of grant of the Award of stock appreciation rights.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.4.3 **<u>Term of Stock Appreciation Right</u>***.* In no event will any stock appreciation right be exercisable after the expiration of ten (10) years from the date on which the stock appreciation right is granted.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.4.4 **<u>Vesting and Exercise of Stock Appreciation Right and Delivery of Shares</u>***.* Each stock appreciation right may vest and be exercised in such installments as may be determined in the Award Agreement at the time the stock appreciation right is granted. Subject to any limitations in the applicable Award Agreement, any stock appreciation rights not exercised on the applicable vesting date may be exercised thereafter at any time before the final expiration of the stock appreciation right.

To exercise a stock appreciation right, the Grantee must give written notice to the Company specifying the number of stock appreciation rights to be exercised. Upon exercise of stock appreciation rights, Shares, cash or other securities or property, or a combination thereof, as specified by the Committee, equal in value to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)the excess of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)the Fair Market Value of the Common Stock on the date of exercise *over* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)the exercise price of such stock appreciation right

*multiplied by* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)the number of stock appreciation rights exercised, will be delivered to the Grantee.

Any person exercising a stock appreciation right will make such representations and agreements and furnish such information as the Committee may, in its sole discretion, deem necessary or desirable to effect or assure compliance by the Company on terms acceptable to the Company with the provisions of the Securities Act, the Exchange Act and any other applicable legal requirements.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.4.5 **<u>No Repricing</u>**. Except as otherwise permitted by <u>Section 1.6.3</u>, reducing the exercise price of stock appreciation rights issued and outstanding under the Plan, including through amendment, cancellation in exchange for the grant of a substitute Award or repurchase for cash or other consideration (in each case that has the effect of reducing the exercise price), will require approval of Byline's stockholders. Byline will not grant any stock appreciation rights with automatic reload features.

**2.5 Restricted Shares**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.5.1 **<u>Grants</u>***.* The Committee may grant or offer for sale restricted Shares in such amounts and subject to such terms and conditions as the Committee may determine. Upon the delivery of such Shares, the Grantee will have the rights of a stockholder with respect to the restricted Shares, subject to any other restrictions and conditions as the Committee may include in the applicable Award Agreement. Each Grantee of an Award of restricted Shares will be issued a Certificate in respect of such Shares, unless the Committee elects to use another system, such as book entries by the transfer agent, as evidencing ownership of such Shares. If the restricted Shares are registered in book-entry form, the restrictions will be placed on the book-entry registration. In the event that a Certificate is issued in respect of restricted Shares, such Certificate may be registered in the name of the Grantee, and will, in addition to such legends required by applicable securities laws, bear an appropriate legend referring to the terms, conditions, and restrictions applicable to such Award, but will be held by the Company or its designated agent until the time the restrictions lapse.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.5.2 **<u>Right to Vote and Receive Dividends on Restricted Shares</u>***.* Each Grantee of an Award of restricted Shares will, during the period of restriction, be the beneficial and record owner of such restricted Shares and will have full voting rights with respect thereto. During the period of restriction, all ordinary cash dividends or other ordinary distributions paid upon any restricted Share will be retained by the Company and will be paid to the relevant Grantee (without interest) when the Award of restricted Shares vests and will revert back to the Company if for any reason the restricted Share upon which such dividends or other distributions were paid reverts back to the Company (any extraordinary dividends or other extraordinary distributions will be treated in accordance with Section <u>1.6.3</u>.

**2.6 Restricted Stock Units**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.6.1 The Committee may grant Awards of restricted stock units in such amounts and subject to such terms and conditions as the Committee may determine. A Grantee of a restricted stock unit will have only the rights of a general unsecured creditor of Byline, until delivery of Shares, cash or other securities or property is made as specified in the applicable Award Agreement. On the delivery date specified in the Award Agreement, the Grantee of each restricted stock unit not previously forfeited or terminated will receive one share of Common Stock, cash or other securities or property equal in value to a share of Common Stock or a combination thereof, as specified by the Committee. Unless otherwise specified in an Award Agreement, in the event that a Non-Employee Director Grantee is removed or terminated as a Director, or otherwise ceases to be a Director, then, subject to and in accordance with the terms of this Plan, each vested restricted stock unit then held by such Non-Employee Director Grantee as of the date of such cessation of services will be settled as of such date.

**2.7 Dividend Equivalent Rights**

The Committee may include in the Award Agreement with respect to any Award a dividend equivalent right entitling the Grantee to receive amounts equal to all or any portion of the regular cash dividends that would be paid on the Shares covered by such Award if such Shares had been delivered pursuant to such Award. The grantee of a dividend equivalent right will have only the rights of a general unsecured

------

creditor of Byline until payment of such amounts is made as specified in the applicable Award Agreement. In the event such a provision is included in an Award Agreement, the Committee will determine whether such payments will be made in cash, in Shares or in another form, whether they will be conditioned upon the exercise of the Award to which they relate (subject to compliance with Section 409A), the time or times at which they will be made, and such other terms and conditions as the Committee will deem appropriate. No dividend equivalents or dividends may be paid to Grantees under this Plan unless and until the Award to which they relate vests. Such prohibition on the payment of dividend equivalents and dividends on unvested awards is applicable to all types of Awards granted under this Plan.

**2.8 Other Stock-Based or Cash-Based Awards**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.8.1 **<u>Grant</u>.** The Committee may grant other types of equity-based, equity-related or cash-based Awards (including retainers and meeting based fees and the grant or offer for sale of unrestricted Shares, performance share awards, and performance units settled in cash) ("**<u>Other Stock-Based or Cash-Based Awards</u>**") in such amounts and subject to such terms and conditions as the Committee may determine. The terms and conditions set forth by the Committee in the applicable Award Agreement may relate to the achievement of Performance Goals, as determined by the Committee at the time of grant. Such Awards may entail the transfer of actual Shares to Award recipients and may include Awards designed to comply with or take advantage of the applicable local laws of jurisdictions other than the United States.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.8.2 **<u>Performance-Based Awards</u>.** Notwithstanding anything to the contrary herein, Other Stock-Based or Cash-Based Awards may, at the discretion of the Committee, be granted subject to the achievement of performance goals or Performance Criteria for an applicable performance period, as determined by the Committee at the time of grant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)**<u>Adjustments</u>**. The Committee may provide for adjustments, modifications or amendments to any of the Performance Criteria, as the Committee may deem appropriate (including, but not limited to, for one or more of the items of gain, loss, profit or expense: (i) determined to be extraordinary or unusual in nature or infrequent in occurrence, (ii) related to the disposal of a segment of a business, (iii) related to a change in accounting principle under generally accepted accounting principles ("**<u>GAAP</u>**"), (iv) related to discontinued operations that do not qualify as a segment of business under GAAP or (v) attributable to the business operations of any entity acquired by the Company during the fiscal year).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)**<u>Determination of Performance</u>.** The Committee will have the sole discretion to determine the extent to which the applicable performance goals or Performance Criteria have been met and ascertain the amount of the applicable Performance-Based Award. The Committee, in its sole discretion, may make adjustments to the amounts payable in respect of the applicable performance goals or Performance Criteria, to the extent consistent with the terms of the applicable Award Agreement. The amount of the Performance-Based Award determined by the Committee for a performance period will be paid to the Grantee at such time as determined by the Committee in its sole discretion.

**2.9 Repayment If Conditions Not Met**

If the Committee determines that all terms and conditions of the Plan and a Grantee's Award Agreement were not satisfied, and that the failure to satisfy such terms and conditions is material, then the Grantee will be obligated to pay the Company immediately upon demand therefor, (a) with respect to a stock option and a stock appreciation right, an amount equal to the excess of the Fair Market Value (determined at the time of exercise) of the Shares that were delivered in respect of such exercised stock option or stock appreciation right, as applicable, over the exercise price paid therefor, (b) with respect to restricted Shares, an amount equal to the Fair Market Value (determined at the time such shares became vested) of such restricted Shares and (c) with respect to restricted stock units, an amount equal to the Fair Market Value (determined at the time of delivery) of the Shares delivered with respect to the applicable delivery date, in each case with respect to clauses (a), (b) and (c) of this <u>Section 2.9</u>, without reduction for any amount applied to satisfy withholding tax or other obligations in respect of such Award.

**ARTICLE III**

**MISCELLANEOUS**

**3.1 Amendment of the Plan**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.1.1 Unless otherwise provided in the Plan or in an Award Agreement, the Board may at any time and from time to time suspend, discontinue, revise or amend the Plan in any respect whatsoever but, subject to <u>Sections</u> <u>1.3</u>, <u>1.6.3</u> and <u>3.7</u>, no such amendment may materially adversely impair the rights of the Grantee of any Award without the Grantee's consent.

**3.2 Tax Withholding**

Grantees will be solely responsible for any applicable taxes (including, without limitation, income and excise taxes) and penalties, and any interest that accrues thereon, that they incur in connection with the receipt, vesting or exercise of any Award. As a condition to the delivery of any Shares, cash or other securities or property pursuant to any Award or the lifting or lapse of restrictions on any Award, or in connection with any other event that gives rise to a federal or other governmental tax withholding obligation on the part of the Company relating to an Award (including, without limitation, the Federal Insurance Contributions Act (FICA) tax),

**3.3 Required Consents and Legends**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.3.1 If the Committee at any time determines that any Consent (as hereinafter defined) is necessary or desirable as a condition of, or in connection with, the granting of any Award, the delivery of Shares or the delivery of any cash, securities or other property under the Plan, or the taking of any other action thereunder (each such action a "**<u>Plan Action</u>**"), then, subject to <u>Section 3.15</u> such Plan Action will not be taken, in whole or in part, unless and until such Consent will have been effected or obtained to the full satisfaction of the Committee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)any and all consents or authorizations required to comply with, or required to be obtained under, applicable local law or otherwise required by the Committee.

**3.4 Right of Offset**

The Company will have the right to offset against its obligation to deliver Shares (or other property or cash) under the Plan or any Award Agreement any outstanding amounts (including, without limitation, travel and entertainment or advance account balances, loans, repayment obligations under any Awards, or amounts repayable to the Company pursuant to other employee programs, including tax equalization) that the Grantee then owes to the Company and any amounts the Committee otherwise deems appropriate pursuant to any tax equalization policy or agreement. Notwithstanding the foregoing, the Committee will have no right to offset against its obligation to deliver Shares (or other property or cash) under the Plan or any Award Agreement if such offset could subject the Grantee to the additional tax imposed under Section 409A.

**3.5 Nonassignability; No Hedging**

Unless otherwise provided in an Award Agreement, no Award (or any rights and obligations thereunder) granted to any person under the Plan may be sold, exchanged, transferred, assigned, pledged, hypothecated or otherwise disposed of or hedged, in any manner (including through the use of any cash-settled instrument), whether voluntarily or involuntarily and whether by operation of law or otherwise, other than by will or by the laws of descent and distribution, and all such Awards (and any rights thereunder) will be exercisable during the life of the Grantee only by the Grantee or the Grantee's legal representative. Notwithstanding the foregoing, the Committee may permit, under such terms and conditions that it deems appropriate in its sole discretion, a Grantee to transfer any Award to any person or entity that the Committee so determines. Any sale, exchange, transfer, assignment, pledge, hypothecation, or other disposition in violation of the provisions of this <u>Section 3.5</u> will be null and void and any Award which is hedged in any manner will immediately be forfeited. All of the terms and conditions of the Plan and the Award Agreements will be binding upon any permitted successors and assigns.

------

**3.6 Change in Control**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.6.1 In the case of (i) a Grantee other than a Non-Employee Director, if a Grantee's Employment is terminated by the Company or any successor entity thereto without Cause, or the Grantee resigns his or her Employment for Good Reason, in either case, on or within two (2) years after a Change in Control, (A) each Award granted to such Grantee prior to such Change in Control will become fully vested (including the lapsing of all restrictions and conditions) and, as applicable, exercisable and (B) any Shares deliverable pursuant to restricted stock units will be delivered promptly (but no later than 15 days) following such Grantee's termination of Employment and (ii) a Non-Employee Director Grantee, each Award will become fully vested (including the lapsing of all restrictions and conditions) and, as applicable, exercisable upon a Change in Control, and any Shares deliverable pursuant to restricted stock units will be delivered promptly (but no later than 15 days) following such Change in Control. As of the Change in Control date, any outstanding Performance-Based Awards shall be deemed earned at the greater of the target level and the actual performance level at the date of the Change in Control with respect to all open performance periods and will cease to be subject to any further performance conditions but will continue to be subject to time-based vesting following the Change in Control in accordance with the original performance period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.6.2 Notwithstanding the foregoing, in the event of a Change in Control, a Grantee's Award will be treated, to the extent determined by the Committee to be permitted under Section 409A, in accordance with one or more of the following methods as determined by the Committee in its sole discretion: (i) settle such Awards for an amount of cash or securities equal to their value, where in the case of stock options and stock appreciation rights, the value of such awards, if any, will be equal to their in-the-money spread value (if any), as determined in the sole discretion of the Committee; (ii) provide for the assumption of or the issuance of substitute awards that will substantially preserve the otherwise applicable terms of any affected Awards previously granted under the Plan, as determined by the Committee in its sole discretion; (iii) modify the terms of such awards to add events, conditions or circumstances (including termination of Employment or directorship within a specified period after a Change in Control) upon which the vesting of such Awards or lapse of restrictions thereon will accelerate; (iv) deem any performance conditions satisfied at target, maximum or actual performance through closing or provide for the performance conditions to continue (as is or as adjusted by the Committee) after closing or (v) provide that for a period of at least 20 days prior to the Change in Control, any stock options or stock appreciation rights that would not otherwise become exercisable prior to the Change in Control will be exercisable as to all Shares subject thereto (but any such exercise will be contingent upon and subject to the occurrence of the Change in Control and if the Change in Control does not take place within a specified period after giving such notice for any reason whatsoever, the exercise will be null and void) and that any stock options or stock appreciation rights not exercised prior to the consummation of the Change in Control will terminate and be of no further force and effect as of the consummation of the Change in Control. In the event that the consideration paid in the Change in Control includes contingent value rights, earnout or indemnity payments or similar payments, then the Committee will determine if Awards settled under clause (i) above are (a) valued at closing taking into account such contingent consideration (with the value determined by the Committee in its sole discretion) or (b) entitled to a share of such contingent consideration. For the avoidance of doubt, in the event of a Change in Control where all stock options and stock appreciation rights are settled for an amount (as determined in the sole discretion of the Committee) of cash or securities, the Committee may, in its sole discretion, terminate any stock option or stock appreciation right for which the exercise price is equal to or exceeds the per share value of the consideration to be paid in the Change in Control transaction without payment of consideration therefor.

------

**3.7 No Continued Employment or Engagement; Right of Discharge Reserved**

Neither the adoption of the Plan nor the grant of any Award (or any provision in the Plan or Award Agreement) will (1) confer upon any Grantee any right to continued Employment, or other engagement, with the Company, or to remain in the service of Byline or any of its Subsidiaries as a Non-Employee Director, (2) interfere in any way with or affect the right of the Company to terminate, or alter the terms and conditions of, a Grantee's Employment, service as a Non-Employee Director or other engagement at any time, or (3) create any obligation on behalf of the Board to nominate any Non-Employee Director for re-election to the Board by Byline's stockholders.

**3.8 Nature of Payments**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.8.1 Any and all grants of Awards and deliveries of Common Stock, cash, securities or other property under the Plan will be in consideration of services performed or to be performed for the Company by the Grantee. Awards under the Plan may, in the discretion of the Committee, be made in substitution in whole or in part for cash or other compensation otherwise payable to a Grantee. Only whole Shares will be delivered under the Plan. Awards will, to the extent reasonably practicable, be aggregated in order to eliminate any fractional shares. Fractional shares may, in the discretion of the Committee, be forfeited or be settled in cash or otherwise as the Committee may determine.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.8.2 All such grants and deliveries of Shares, cash, securities or other property under the Plan will constitute a special discretionary incentive payment to the Grantee, will not entitle the Grantee to the grant of any future Awards and will not be required to be taken into account in computing the amount of salary or compensation of the Grantee for the purpose of determining any contributions to or any benefits under any pension, retirement, profit-sharing, bonus, life insurance, severance or other benefit plan of the Company or under any agreement with the Grantee, unless the Company specifically provides otherwise.

**3.9 Non-Uniform Determinations**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.9.1 The Committee's determinations under the Plan and Award Agreements need not be uniform and any such determinations may be made by it selectively among persons who receive, or are eligible to receive, Awards under the Plan (whether or not such persons are similarly situated). Without limiting the generality of the foregoing, the Committee will be entitled, among other things, to make non-uniform and selective determinations under Award Agreements, and to enter into non-uniform and selective Award Agreements, as to (a) the persons to receive Awards, (b) the terms and provisions of Awards and (c) whether a Grantee's Employment or directorship has been terminated for purposes of the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.9.2 To the extent the Committee deems it necessary, appropriate or desirable to comply with law or practices of jurisdictions other than the United States and to further the purposes of the Plan, the Committee may, in its sole discretion and without amending the Plan, (a) establish special rules applicable to Awards to Grantees who are non-United States nationals, are employed outside the United States or both and grant Awards (or amend existing Awards) in accordance with those rules and (b) cause Byline to enter into an agreement with any local Subsidiary pursuant to which such Subsidiary will reimburse the Company for the cost of such equity incentives.

------

**3.10 Other Payments or Awards**

Nothing contained in the Plan will be deemed in any way to limit or restrict the Company from making any award or payment to any person under any other plan, arrangement or understanding, whether now existing or hereafter in effect.

**3.11 Plan Headings**

The headings in the Plan are for the purpose of convenience only and are not intended to define or limit the construction of the provisions hereof.

**3.12 Termination of Plan**

The Board reserves the right to terminate the Plan at any time; <u>provided</u>*,* <u>however</u>, that in any case, the Plan will terminate on the day before the tenth anniversary of the Effective Date, and <u>provided</u> <u>further</u>, that all Awards made under the Plan before its termination will remain in effect until such Awards have been satisfied or terminated in accordance with the terms and provisions of the Plan and the applicable Award Agreements.

**3.13 Clawback/Recapture Policy**

Awards under the Plan will be subject to any clawback or recapture policy that the Company may adopt from time to time to the extent provided in such policy and, in accordance with such policy, may be subject to the requirement that the Awards be repaid to the Company after they have been distributed to the Grantee.

**3.14 FDIC Limits on Golden Parachute Payments**

Notwithstanding anything to the contrary, the Company will not be required to make any payment or grant any Award under the Plan or any Award Agreement that would otherwise be a prohibited golden parachute payment within the meaning of Section 18(k) of the Federal Deposit Insurance Act.

**3.15** Section 409A

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.15.1 All Awards made under the Plan that are intended to be "deferred compensation" subject to Section 409A will be interpreted, administered and construed to comply with Section 409A, and all Awards made under the Plan that are intended to be exempt from Section 409A will be interpreted, administered and construed to comply with and preserve such exemption. The Board and the Committee will have full authority to give effect to the intent of the foregoing sentence. To the extent necessary to give effect to this intent, in the case of any conflict or potential inconsistency between the Plan and a provision of any Award or Award Agreement with respect to an Award, the Plan will govern.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.15.2 Without limiting the generality of <u>Section 3.15.1</u>, with respect to any Award made under the Plan that is "deferred compensation" subject to Section 409A, in each case to the extent required to comply with Section 409A:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)any payment due upon a Grantee's termination of Employment or ceasing to provide services to the Company will be paid only upon such Grantee's separation from service from the Company within the meaning of Section 409A;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)any payment due upon a Change in Control of the Company will be paid only if such Change in Control constitutes a "change in ownership" or "change in effective control" within the meaning of Section 409A, and in the event that such Change in Control does not constitute a "change in ownership" or "change in effective control" within the meaning of Section 409A, such Award will vest upon the Change in Control and any payment will be delayed until the first compliant date under Section 409A;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)if the Grantee is a "specified employee" within the meaning of Section 409A, any payment to be made with respect to such Award in connection with the Grantee's "separation from service" from the Company within the meaning of Section 409A (and any other payment that would be subject to the limitations in Section 409A(a)(2)(B) of the Code) will be delayed until six months after the Grantee's separation from service (or earlier death) in accordance with the requirements of Section 409A;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)any other securities, other Awards or other property that the Company may deliver in lieu of Shares in respect of an Award will not have the effect of deferring delivery or payment beyond the date on which such delivery or payment would occur with respect to the Shares that would otherwise have been deliverable (unless the Committee elects a later date for this purpose in accordance with the requirements of Section 409A);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)with respect to any required Consent described in <u>Section 3.3</u> or the applicable Award Agreement, if such Consent has not been effected or obtained as of the latest date provided by such Award Agreement for payment in respect of such Award and further delay of payment is not permitted in accordance with the requirements of Section 409A, such Award or portion thereof, as applicable, will be forfeited and terminate notwithstanding any prior earning or vesting;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)if the Award includes a "series of installment payments" (within the meaning of Section 1.409A-2(b)(2)(iii) of the Treasury Regulations), the Grantee's right to the series of installment payments will be treated as a right to a series of separate payments and not as a right to a single payment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g)if the Award includes "dividend equivalents" (within the meaning of Section 1.409A-3(e) of the Treasury Regulations), the Grantee's right to the dividend equivalents will be treated separately from the right to other amounts under the Award; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h)for purposes of determining whether the Grantee has experienced a separation from service from the Company within the meaning of Section 409A, "subsidiary" will mean a corporation or other entity in a chain of corporations or other entities in which each corporation or other entity, starting with Byline, has a controlling interest in another corporation or other entity in the chain, ending with such corporation or other entity. For purposes of the preceding sentence, the term "controlling interest" has the same meaning as provided in Section 1.414(c)-2(b)(2)(i) of the Treasury Regulations, <u>provided</u> <u>that</u> the language "at least 20 percent" is used instead of "at least 80 percent" each place it appears in Section 1.414(c)-2(b)(2)(i) of the Treasury Regulations.

**3.16 Governing Law**

THE PLAN AND ALL AWARDS MADE AND ACTIONS TAKEN THEREUNDER WILL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF Illinois, WITHOUT REFERENCE TO PRINCIPLES OF CONFLICT OF LAWS.

------

**3.17 Disputes; Choice of Forum**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.17.1 The Company and each Grantee, as a condition to such Grantee's participation in the Plan, hereby irrevocably submit to the exclusive jurisdiction of any state or federal court located in the Cook County, Illinois, over any suit, action or proceeding arising out of or relating to or concerning the Plan or, to the extent not otherwise specified in any individual agreement between the Company and the Grantee, any aspect of the Grantee's Employment or continuation of service with the Company or the termination of that Employment or service. The Company and each Grantee, as a condition to such Grantee's participation in the Plan, acknowledge that the forum designated by this <u>Section 3.17.1</u> has a reasonable relation to the Plan and to the relationship between such Grantee and the Company. Notwithstanding the foregoing, nothing herein will preclude the Company from bringing any action or proceeding in any other court for the purpose of enforcing the provisions of this <u>Section 3.17.1</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.17.2 The agreement by the Company and each Grantee as to forum is independent of the law that may be applied in the action, and the Company and each Grantee, as a condition to such Grantee's participation in the Plan, (i) agree to such forum even if the forum may under applicable law choose to apply non-forum law, (ii) hereby waive, to the fullest extent permitted by applicable law, any objection which the Company or such Grantee now or hereafter may have to personal jurisdiction or to the laying of venue of any such suit, action or proceeding in any court referred to in <u>Section 3.17.1</u>, (iii) undertake not to commence any action arising out of or relating to or concerning the Plan in any forum other than the forum described in this <u>Section 3.17</u> and (iv) agree that, to the fullest extent permitted by applicable law, a final and non-appealable judgment in any such suit, action or proceeding in any such court will be conclusive and binding upon the Company and each Grantee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.17.3 Each Grantee, as a condition to such Grantee's participation in the Plan, hereby irrevocably appoints the General Counsel, or, to the extent there is no individual serving in that role, the Corporate Development Officer, of the Company as such Grantee's agent for service of process in connection with any action, suit or proceeding arising out of or relating to or concerning the Plan, who will promptly advise such Grantee of any such service of process.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.17.4 Each Grantee, as a condition to such Grantee's participation in the Plan, agrees to keep confidential the existence of, and any information concerning, any dispute or controversy or any claim described in <u>Section 3.19</u>. Notwithstanding the foregoing, a Grantee may disclose information concerning such dispute, controversy or claim to the court that is considering such dispute, controversy or claim or to such Grantee's legal counsel (provided that such counsel agrees not to disclose any such information other than as necessary to the prosecution or defense of the dispute, controversy or claim). In addition, a Grantee may provide information to, file a charge with or participate in an investigation conducted by, any governmental entity, and a Grantee does not need the Company's permission to do so. Furthermore, a Grantee is not required to notify the Company of a request for information from any governmental entity or of such Grantee's decision to file a charge with or participate in an investigation conducted by any governmental entity.

**3.18 Waiver of Jury Trial**

EACH GRANTEE WAIVES ANY RIGHT IT MAY HAVE TO TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED ON, ARISING OUT OF, UNDER OR IN CONNECTION WITH THE PLAN.

------

**3.19 Waiver of Claims**

Each Grantee of an Award recognizes and agrees that before being selected by the Committee to receive an Award the Grantee has no right to any benefits under the Plan. Accordingly, in consideration of the Grantee's receipt of any Award hereunder, the Grantee expressly waives any right to contest the amount of any Award, the terms of any Award Agreement, any determination, action or omission hereunder or under any Award Agreement by the Committee, the Company or the Board, or any amendment to the Plan or any Award Agreement (other than an amendment to the Plan or an Award Agreement to which his or her consent is expressly required by the express terms of an Award Agreement). Nothing contained in the Plan, and no action taken pursuant to its provisions, will create or be construed to create a trust of any kind or a fiduciary relationship between the Company and any Grantee. The Plan is not intended to be subject to the Employee Retirement Income Security Act of 1974 (ERISA), as amended.

**3.20 Severability; Entire Agreement**

If any of the provisions of the Plan or any Award Agreement is finally held to be invalid, illegal or unenforceable (whether in whole or in part), such provision will be deemed modified to the extent, but only to the extent, of such invalidity, illegality or unenforceability and the remaining provisions will not be affected thereby; <u>provided</u> <u>that</u> if any of such provisions is finally held to be invalid, illegal, or unenforceable because it exceeds the maximum scope determined to be acceptable to permit such provision to be enforceable, such provision will be deemed to be modified to the minimum extent necessary to modify such scope in order to make such provision enforceable hereunder. The Plan and any Award Agreements contain the entire agreement of the parties with respect to the subject matter thereof and supersede all prior agreements, promises, covenants, arrangements, communications, representations and warranties between them, whether written or oral with respect to the subject matter thereof.

**3.21 No Liability With Respect to Tax Qualification or Adverse Tax Treatment**

Notwithstanding anything to the contrary contained herein, in no event will the Company be liable to a Grantee on account of an Award's failure to (a) qualify for favorable United States or non-United States tax treatment or (b) avoid adverse tax treatment under United States or non-United States law, including, without limitation, Section 409A.

**3.22 No Third-Party Beneficiaries**

Except as expressly provided in an Award Agreement, neither the Plan nor any Award Agreement will confer on any person other than the Company and the Grantee of any Award any rights or remedies thereunder. The exculpation and indemnification provisions of <u>Section 1.3.4</u> will inure to the benefit of a Designated Person's estate and beneficiaries and legatees.

**3.23 Successors and Assigns of the Company**

The terms of the Plan will be binding upon and inure to the benefit of the Company and any successor entity, including as contemplated by <u>Section 3.6</u>.

**3.24 Date of Adoption and Approval of Stockholders**

The Plan was adopted by the Board on April 7, 2026 and was approved by Byline's stockholders on June 2, 2026 (the "**<u>Effective Date</u>**").
