~~TABLE OF CONTENTS~~

~~About the Meeting~~

What constitutes a quorum?

The presence at the meeting, in person (virtually) or by proxy, of the holders of common stock representing a majority of the combined voting power of the outstanding shares of common stock on the record date will constitute a quorum, permitting the meeting to conduct its business. Proxies received but marked as abstentions will be included in the calculation of the number of shares considered to be present at the meeting for purposes of determining a quorum. As of the record date, there were ~~37,804,381~~37,709,728 shares of common stock outstanding, all of which are entitled to be voted at the Annual Meeting. If less than a majority of the combined voting power of the outstanding shares of common stock is represented at the Annual Meeting, either the Chairperson of the meeting or holders of a majority of the shares so represented may adjourn the Annual Meeting from time to time without further notice.

What vote is required to approve each item?

The votes required to approve the matters to be presented at the Annual Meeting as listed in the Notice of the Annual Meeting are as follows:

•

For purposes of electing directors at the Annual Meeting, directors will be elected by a plurality of the votes of the shares present (virtually) or represented by proxy at the meeting and entitled to vote on the election of directors. Accordingly, the director nominees receiving the most votes of the holders of our common stock will be elected as directors.

•

For all other matters, including the approval of the amendment ofto the ~~Company’s Employee Stock Purchase~~Byline Bancorp, Inc. 2017 Omnibus Incentive Compensation Plan to increase the number of shares ~~of common stock that may be offered~~available for issuance under the ~~plan,~~plan; the approval of, on an advisory (non-binding) basis, the compensation of the Company’s named executive officers as described in this Proxy Statement; the approval of, on an advisory (non-binding) basis, the frequency of future stockholder advisory votes to approve the compensation of the Company’s named executive officers; as well as ~~for~~ the ratification of the appointment of Moss Adams LLP as our independent registered public accounting firm for the fiscal year ending December 31, ~~2022, as well as for~~2023, approval requires the affirmative vote of the holders of a majority of the shares present in person (virtually) or represented by proxy at the Annual Meeting and entitled to vote on the subject matter.

For purposes of Proposals 2 and 3, proxies received but marked as abstentions will be included in the calculation of the number of shares considered to be present at the meeting for purposes of determining a quorum. Pursuant to our By-laws, broker non-votes will not be counted as shares entitled to vote on such matters and will have no effect on the outcome of such matters. Votes cast “for” or “against” and abstentions with respect to such matters will be counted as shares entitled to vote on such matters. A “broker non-vote” will occur when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary power with respect to that proposal and has not received instructions from the beneficial owner. On matters other than the election of directors, abstentions will have the effect of a vote “against” such matters. If less than a majority of the combined voting power of the outstanding shares of common stock is represented at the Annual Meeting, either the Chairperson of the meeting or a majority of the shares so represented may adjourn the Annual Meeting from time to time without further notice.

The inspector of election for the Annual Meeting will determine the number of shares of common stock represented at the meeting, the existence of a quorum, and the validity and effect of proxies, and shall count and tabulate ballots and votes and determine the results thereof.

Please note that if you hold your shares in “street name,” your bank, broker or other nominee will not be permitted to vote your shares on either ~~Proposal~~Proposals 1, ~~(election of directors) or Proposal~~ 2, ~~(amendment of the ESPP)~~3 and 4 absent specific instructions from you. Therefore, it is important that you follow the voting instructions on the form that you receive from your bank, broker, or other nominee.

What are the Board’s recommendations?

Our Board of Directors ~~recommends~~ recommends:

•

a vote FOR the election of all of the respective nominees for director named in this Proxy ~~Statement,~~ Statement;

•

a vote FOR the approval of an amendment to the ~~Company’s Employee Stock Purchase~~Byline Bancorp, Inc. 2017 Omnibus Incentive Compensation Plan to increase the number of shares ~~of common stock that may be offered~~available for issuance under the ~~plan,~~ Plan;

•

a vote FOR the approval of, on an advisory (non-binding) basis, the compensation of the Company’s named executive officers as described in this Proxy Statement;

~~TABLE OF CONTENTS~~

~~About the Meeting~~

Annual Meeting. In the event a stockholder specifies a different choice by means of the proxy, such shares will be voted in accordance with the specification made.

How do I vote?

If you are a holder of record (that is, if your shares are registered in your own name with our transfer agent), you may vote using the proxy card contained in the proxy materials. Voting instructions are provided on the proxy card. The Notice also includes information about how to vote via the Internet (at www.proxyvote.com) or via telephone (1-800-690-6903).

If you are a street name holder (that is, if you hold your shares through a bank, broker, or other holder of record), you must provide your voting instructions in accordance with the voting instruction form provided by your bank, broker, or other holder of record, who will then vote your shares on your behalf. The availability of telephone or Internet voting will depend upon your bank’s, broker’s, or other holder of record’s voting process.

If you ~~virtually~~ attend the Annual Meeting virtually, you can vote your shares at that time.

Can I change my vote?

Yes. The giving of a proxy does not eliminate the right to vote at the Annual Meeting should any stockholder giving the proxy so desire. Stockholders have an unconditional right to revoke their proxy at any time prior to the exercise of that proxy, by (1) voting at the Annual Meeting, or (2) by filing a written revocation or duly executed proxy bearing a later date with our Secretary.

Corporate Governance

Composition of Our Board of Directors

Our Board of Directors currently has ~~nine~~eight members. Under our Amended and Restated Certificate of Incorporation and By-Laws, the number of directors constituting our Board of Directors is fixed from time to time by resolution of the Board of Directors. The Board met ~~eight~~seven times during ~~2021.~~2022. Our Lead Director, Mr. del Valle, is related to the Company’s SVP, Director of Legal, Ana Casanueva, as first cousin.

Board Leadership Structure and Qualifications

We believe that our directors should have the highest professional and personal ethics and values, consistent with our longstanding values and standards. They should have broad experience at the policy making level in business, government, or banking. They should be committed to enhancing stockholder value and should have sufficient time to carry out their duties and to provide insight and practical wisdom based on experience. Each director must represent the interests of all stockholders.

When considering potential director candidates, our Board of Directors considers the candidate’s character, judgment, diversity, skills, including financial literacy, and experience in the context of our needs and those of the Board of Directors. Our Board also considers the candidate’s service on boards of other companies and whether such service would impair the candidate’s ability to perform responsibly all director duties for Byline.

Our Board of Directors does not have a formal policy requiring the separation of the roles of Chief Executive Officer and Chairman of the Board. It is the Board of Directors’ view that rather than having a rigid policy, the Board of Directors, with the advice and assistance of the Governance and Nominating Committee, and upon consideration of all relevant factors and circumstances, will determine, as and when appropriate, whether the two offices should be separate. Currently, Mr. Herencia holds the combined positions of Executive Chairman of the Board and Chief Executive Officer, while Mr. Paracchini is President of the Company, as well as President and Chief Executive Officer of Byline Bank. Also, Mr. del Valle Perochena ~~was appointed~~has been the Lead Director of the Company insince February ~~2021 upon the assumption by Mr. Herencia of the Executive Chairman and Chief Executive Officer roles.~~2021. We believe this current structure provides the appropriate level of oversight and management, as well as intends to accelerate and support the execution of the Company’s strategic plan, specifically its growth strategy, as a leading commercial bank in the Chicago ~~MSA.~~Metropolitan Area.

Diversity

Our Board believes that a range of experience, knowledge, and judgement, as well as a diversity of perspectives, geographic regions, gender, race, and national origin on the Board, enhances the overall effectiveness of the Board. At present, the overall diversity atof our Board is ~~67%~~75%. Gender diversity accounts for ~~22%~~25% of the overall diversity, and race or ethnic diversity accounts for ~~56%~~63% of the overall diversity. During ~~2021,~~2022, the Company ~~focused~~continued increasing its focus on Diversity, Equity, and Inclusion (DEI) initiatives to ensure we are doing the work necessary to make the Company a safe and welcoming place for all of our employees and customers. ~~With the~~The Board has increased its support of the ~~Board, the Company appointed a~~Company’s DEI Council, which has acted as the foundation and catalyst for honoring our employees, engaging our customers and community, creating a great place to work, and ultimately driving business success. For further information regarding our DEI initiatives, please see the section in this Proxy Statement titled “Human Capital and Social Responsibility.”

Director Independence

Under the rules of the New York Stock Exchange (“NYSE”), independent directors must comprise a majority of our Board of Directors. The rules of the NYSE, as well as those of the SEC, impose several requirements with respect to the independence of our directors. Our Board of Directors has undertaken a review of the independence of each director in accordance with these rules. Based on information provided by each director concerning his or her background, employment and affiliations, our Board of Directors has determined that each of Phillip R. Cabrera, Antonio del Valle Perochena, Mary Jo S. Herseth, Margarita Hugues ~~Velez,~~Vélez, Steven P. Kent, and William G. Kistner ~~and Steven M. Rull~~ do not have relationships that would interfere with the exercise of their independent judgment in carrying out the responsibilities of a director and that each of these directors is “independent” as that term is defined under the applicable rules. Our Board of Directors has determined that Messrs. del Valle Perochena, Cabrera and Kent also satisfy the heightened independence requirements for ~~compensation committee~~Compensation Committee members, and that Messrs.

~~Agreement with Mr. Herencia~~

In January of 2021, the Board conducted a deep evaluation of our then Chairman, Mr. Herencia, and his significant ongoing involvement with the Company’s management and his ability to have a substantial and positive impact on the execution of the Company’s strategy. The Board announced the appointment of Mr. Herencia as Executive Chairman and Chief Executive Officer of Byline Bancorp, Inc., effective as of February 12, 2021. In connection with the assumption of this expanded role, we entered into a new employment agreement with Mr. Herencia (the “Employment Agreement”), which is summarized as follows.

The Employment Agreement is for an initial term of three years and includes an automatic one-year extension at the end of each term following the initial term unless notice of termination is provided not less than 120 days prior to the end of such term. In addition, the Employment Agreement will terminate on the termination of Mr. Herencia’s employment. Upon the occurrence of a Change in Control (as such term is defined in the Employment Agreement), the term of the Employment Agreement will renew for the period expiring on the second anniversary of such Change in Control and will automatically renew for one year on each subsequent anniversary of such date thereafter, unless at any time not less than 120 days prior to the end of such term either Byline or Mr. Herencia notifies the other in writing of the intention not to further extend the term.

During the term of the Employment Agreement, Mr. Herencia serves as Executive Chairman and Chief Executive Officer of the Byline, reporting to the Board, and Executive Chairman of the Board of Directors of the Bank.

In connection with entering into the Employment Agreement, Mr. Herencia was awarded a restricted stock award of 109,475 shares of Byline’s common stock under the 2017 Plan, vesting in equal installments at the end of 2021, 2022 and 2023.

The Employment Agreement also includes severance benefits that are subject to signing a release. If we terminate Mr. Herencia without “cause” (and not due to Disability (as such term is defined in the Employment Agreement) or Mr. Herencia resigns for “good reason” (provided that the expiration of the term of the Employment Agreement following the delivery by Byline of a notice of non-renewal of such term shall be deemed to be a termination of Mr. Herencia’s employment by Byline without “cause”), other than on or following the occurrence of a Change in Control, he will be entitled to (each capitalized term as defined in the Employment Agreement): (1) the Accrued Amounts and any Unpaid EIP; (2) a Pro Rata Bonus; and (3) a cash amount equal to the sum of (a) the Severance Amount plus (b) the Applicable COBRA Amount, payable in substantially equal installments over 24 months following termination of employment.

The 142,913 remaining available shares combined with the ~~Company’s current~~proposed 1,050,000 would provide a total of 1,192,913 shares available to be granted during the remaining term of the plan until its expiration in 2027.

•

The proposed additional 1,050,000 shares represent 2.78% of our outstanding common stock ~~price, we estimate~~as of April 12, 2023.

•

The Board of Directors is recommending that inour stockholders approve the ~~absence~~amendment of ~~approval of~~the 2017 Omnibus Plan to add 1,050,000 shares because it believes the increase in the number of shares reserved for issuance is consistent with the interests of ~~common stock that may be offered under~~our stockholders.

In analyzing the ~~ESPP, all such shares could be substantially exhausted before~~proposed amendment of the ~~end~~Plan, our Compensation Committee and Board of ~~2023. If~~Directors engaged an independent compensation consultant, Pearl Meyer & Partners, LLC, to assist with recommending the ~~amendment is approved by stockholders,~~size of the ~~number of shares available under the ESPP will be increased to 400,000. We believe that this~~proposed increase in the number of shares ~~available~~that may be issued under the ~~ESPP will enable eligible persons to participate under~~Plan. In doing so, the ~~ESPP until approximately December 31, 2027, based on current participation levels~~Compensation Committee and the ~~current price~~Board considered both our historical and expected burn rate and the resulting overhang as outlined below:

•

Burn Rate; Longevity of ~~our common stock.~~

~~Summary~~Authorized Shares. Burn rate (the measure of the ~~ESPP~~

annual rate at which companies use shares available for grant in their equity compensation plans), is an important factor for stockholders concerned about stockholder dilution. The ~~following~~burn rate is ~~a description of the material~~defined in terms of the ~~ESPP, as proposed to~~gross number of equity awards granted during a calendar year divided by the weighted average of number of shares of common stock outstanding during the year. We calculate our annual burn rate by adding the number of stock options granted plus the number of full value shares awarded and dividing the total by the number of weighted average common shares outstanding. Our burn rate for the fiscal years ended 2022, 2021, and 2020 was 0.81%, 0.85% and 0.46%, respectively. We believe our current three-year average burn rate of 0.71% should be ~~amended. This description is qualified in its entirely~~viewed favorably by ~~reference to~~our stockholders. We do not anticipate that projected issuances of future awards under the ~~plan document, as proposed to be amended, a copy of which is attached to this~~Plan

Proposal 2: To approve an amendment to the ~~Company’s Employee Stock Purchase~~Byline Bancorp, Inc. 2017 Omnibus Incentive Compensation Plan to increase the

will vary materially from our historical awards and estimate that the additional 1,050,000 shares proposed to be authorized for issuance under the Plan will be sufficient for future grants through the life of the Plan.

•

Overhang. Overhang is a measure that is sometimes used to assess the aggregate dilutive impact of equity programs such as the Plan. Overhang indicates the amount by which existing stockholder ownership would be diluted if the shares authorized for issuance under the 2017 Omnibus Plan, coupled with the shares subject to outstanding awards, were issued. As of April 12, 2023, the Company had outstanding equity awards of 930,852 stock options with a weighted average exercise price of $11.37 and weighted average remaining term of 2.5 years, and 677,271 restricted stock awards outstanding, and 142,281 available for issuance, which, in aggregate, represents an overhang of approximately 4.6%. The approval of the additional 1,050,000 shares to be authorized for issuance under the Plan would result in overhang of approximately 7.4% relative to the approximately 37,709,728 shares outstanding as of April 12, 2023. We believe this level of overhang should not be viewed as excessive by our stockholders.

Stockholder Approval; Best Practices

The 2017 Omnibus Plan reflects current practices in equity incentive plans that we consider best practices such as:

•

Independent Oversight. The 2017 Omnibus Plan is administered by the Compensation Committee, which is comprised of independent members of our board of directors.

•

Double Trigger Change in Control Provisions. The change in control provisions under the 2017 Omnibus Plan do not provide for automatic acceleration of vesting of awards in the event of a change in control. Vesting of outstanding awards will occur if an employee incurs a termination of service without cause or for good reason on or within the two-year period following the change in control.

•

No Evergreen Feature. The 2017 Omnibus Plan does not include an “evergreen” feature that would cause the number of authorized shares to automatically increase in future years.

•

Conservative Share Reuse Provision. Shares subject to an award under the 2017 Omnibus Plan will not be available for reuse if such shares are tendered in payment of a stock option exercise price, delivered or withheld to satisfy any tax withholding obligation, or covered by a stock appreciation right (SAR) (to the extent settled in shares) or other award. Additionally, shares that have been repurchased by the Company using stock option exercise proceeds are not added back to the share reserve.

•

Awards Subject to Clawback. All awards under the 2017 Omnibus Plan will be subject to any applicable law respecting recapture of compensation or such Company Compensation Clawback policy as may be in effect at the time of grant.

•

Forfeiture Provisions. In the event the Committee determines that a participant fails to satisfy all of the material terms and conditions of an award, which may include, breach of a restrictive covenant, the participant will forfeit all outstanding awards and repay to the Company upon demand any shares or profits realized with respect to such award.

•

Multiple Award Types. The 2017 Omnibus Plan permits the issuance of stock options, stock appreciation rights, restricted shares, and other types of equity and cash incentive grants, subject to the share limits of the plan. This breadth of award types will enable the Compensation Committee to tailor awards in light of the accounting, tax and other standards applicable at the time of grant.

•

No Repricing without Stockholder Approval. The exercise price of stock options and SARs may not be reduced, including through amendment, cancellation and exchange for another award or cash payment or other consideration, without approval of the Company’s stockholders.

Description of the 2017 Omnibus Plan

The following is a description of the terms of the 2017 Omnibus Plan. This description is qualified in its entirety by reference to the plan document, incorporated herein by reference.

General Information Regarding the Plan

The Board adopted the 2017 Omnibus Plan, and Byline’s stockholders approved it, in connection with our initial public offering. The purpose of the 2017 Omnibus Plan is to attract, retain and motivate key employees (including

26 Byline Bancorp, Inc. 2023 Proxy Statement

Proposal 2: To approve an amendment to the Byline Bancorp, Inc. 2017 Omnibus Incentive Compensation Plan to increase the

number of shares available for issuance under the plan

prospective employees), consultants and non-employee directors of the Board who may perform services for the Company and its subsidiaries, to align their interests with the interests of Byline’s stockholders and to promote ownership of Byline’s equity by award grantees. To accomplish this purpose the 2017 Omnibus Plan provides for the grant of stock options (both stock options intended to meet the requirements of “incentive stock options” under Section 422 of the Code and “non-qualified stock options” that do not meet such requirements), stock appreciation rights (“SARs”), restricted stock, restricted stock units, dividend equivalent rights and other equity-based, equity-related or cash-based awards (including performance share awards and performance units settled in cash) (collectively, “awards”).

The Board may from time to time suspend, discontinue, revise or amend the 2017 Omnibus Plan in any respect but, subject to certain exceptions, no such amendment may materially adversely impair the rights of a grantee without the grantee’s consent. Unless sooner terminated by the Board, the 2017 Omnibus Plan will terminate on June 14, 2027 (the tenth anniversary of the date on which the 2017 Omnibus Plan became effective), but awards previously granted will remain in effect until such awards have been satisfied or terminated in accordance with the terms and provisions of the Plan and applicable award agreements.

The 2017 Omnibus Plan is not subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended, nor is it qualified (or intended to be qualified) under Section 401(a) of the Internal Revenue Code of 1986, as amended (the “Code”).

Shares Subject to the 2017 Omnibus Plan

A total of 1,550,000 shares of our common stock are currently reserved under the 2017 Omnibus Plan. If an award granted under the 2017 Omnibus Plan expires, is forfeited or is settled in cash, the shares of our common stock not acquired pursuant to the award will again become available for subsequent issuance under the 2017 Omnibus Plan. Shares of our common stock subject to awards that are assumed, converted or substituted under the 2017 Omnibus Plan as a result of our acquisition of another company will not be counted against the number of shares that may be granted under the 2017 Omnibus Plan. With respect to awards of stock-settled SARs, the total number of shares that may be granted under the 2017 Omnibus Plan will be reduced by the full number of shares underlying the exercised portion of such award (rather than only the number of shares actually delivered upon exercise). The following types of shares under the 2017 Omnibus Plan will not again become available for the grant of new awards under the 2017 Omnibus Plan: (i) shares withheld to satisfy any tax withholding obligation, (ii) shares tendered to, or withheld by, us to pay the exercise price of an option and (iii) shares covered by a SAR (to the extent that it is settled in shares).

The aggregate number of shares of our common stock that may be ~~offered under the plan~~

~~and last for~~granted to any employee during a period of six months. The Compensation Committee will establish an enrollment period, a period of time prior to the beginning of an offering during which eligible participants may subscribe to an offering in such manner as the Compensation Committee may prescribe (which may include enrollment by submitting forms, by voice response, internet access or other electronic means). Eligible employees elect whether to participatefiscal year in the ~~ESPP (i.e., have deductions made from their after-tax compensation~~form of awards (other than stock options and SARs) that are intended to be “performance-based compensation” for purposes of Section 162(m) of the ~~purpose~~Code, may not exceed 184,211 shares.

The maximum number of shares of our common stock that may be granted to any single individual during a ~~participant~~fiscal year in the form of SARs may not exceed 200,000 shares. 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 ~~an offering commences~~of grant.

Administration of the 2017 Omnibus Plan

The 2017 Omnibus Plan is ~~deemed~~administered by the Compensation Committee of the Board, (and its delegates) unless the Board determines otherwise. Subject to the terms of the 2017 Omnibus Plan, the Compensation Committee determines which employees, consultants and non-employee directors will receive awards under the 2017 Omnibus Plan, the dates of grant, the number and types of awards to be granted, ~~an option~~the exercise or purchase price of each award, and the terms and conditions of the awards, including the period of their exercisability and vesting and the fair market value applicable to ~~participate~~a stock award.

In addition, the Compensation Committee has the authority to determine whether any award may be settled in cash, shares of our common stock, other securities or other awards or property. The Compensation Committee has the ~~ESPP for that offering.~~authority to interpret the 2017 Omnibus Plan and may adopt any administrative rules, regulations, procedures and guidelines governing the 2017 Omnibus Plan or any awards granted under the 2017 Omnibus Plan as it deems to be appropriate. The Compensation Committee may also ~~establish~~delegate any of its powers, responsibilities or duties to any person

The Compensation Committee may ~~also provide~~condition the vesting of or the lapsing of any applicable vesting restrictions or conditions on awards upon the attainment of performance goals, continuation of service, or any other term or conditions. The vesting conditions placed on any award need not be the same with respect to each grantee and the Compensation Committee has the sole discretion to amend any outstanding award to accelerate or waive any or all restrictions, vesting provisions or conditions set forth in the award agreement.

Each award granted under the 2017 Omnibus Plan shall be evidenced by an award agreement, which shall govern that award’s terms and conditions. In the case of any conflict or potential inconsistency between the 2017 Omnibus Plan and a provision of any award or award agreement with respect to an award, the 2017 Omnibus Plan shall govern.

Types of Awards

The 2017 Omnibus Plan provides for ~~periodic~~the grant of stock options intended to meet the requirements of “incentive stock options” under Section 422 of the Code as well as “non-qualified stock options” that do not meet such requirements, SARs, restricted stock, restricted stock units, dividend equivalent rights and other equity-based, equity-related or cash-based awards (including performance-based awards).

Stock Options

An award of a stock option gives a grantee the right to purchase ~~dates~~a certain number of shares of our common stock during a specified term in the future, after a vesting period (if any), at an ~~offering period.~~

~~A participant can change his~~exercise price equal to at least 100% of the fair market value of our common stock on the grant date. The term of a stock option may not exceed 10 years from the date of grant. Incentive stock options may only be granted from a plan that has been approved by our stockholders and will be exercisable in any fiscal year only to the extent that the aggregate fair market value of our common stock with respect to which the incentive stock options are exercisable for the first time does not exceed $100,000. No incentive stock option may be granted to any person who, at the time of the grant, owns or her level of withholding or withdraw his or her subscription at any time (but not retroactively), during an offering, subject to rules and limitations established by the Plan Administrator. A participant whose employment is terminated during an offering period is deemed to ~~have withdrawn his~~own stock possessing more than 10% of our total combined voting power or ~~her subscription. Upon~~that of any of our affiliates unless (i) the ~~withdrawal (or deemed withdrawal)~~option exercise price is at least 110% of ~~a participant,~~ the ~~balance in his or her account will either be refunded or used~~fair market value of the stock subject to ~~purchase shares~~the option on the ~~next purchased~~ date ~~as determined~~of grant and (ii) the term of the incentive stock option does not exceed five years from the date of grant.

~~Purchase Price~~Stock Appreciation Rights (SARs)

~~The purchase~~A SAR entitles the grantee to receive an amount equal to the difference between the fair market value of our common stock on the exercise date and the exercise price ~~paid by participants for~~of the ~~shares purchased under the ESPP is set by the Compensation Committee and will, in any case,~~SAR (which may not be no less than ~~85% of the lower~~100% of the fair market value of a share of our common stock on the ~~first day~~grant date), multiplied by the number of shares subject to the ~~applicable offering period or on the purchase date. Unless provided otherwise, the default purchase price per share provided for in the ESPP will be 85% of the fair market value~~SAR. The term of a ~~share~~SAR may not exceed 10 years from the date of grant. Payment to a grantee upon the exercise of a SAR may be either in cash, shares of our common stock ~~on the last day~~or other securities or property, or a combination of the ~~applicable offering period or earlier purchase date.~~

~~Limitations on Purchase~~

~~As required~~foregoing, as determined by the ~~Code, no eligible employee may purchase~~Compensation Committee.

Restricted Stock

A restricted stock ~~under the ESPP at a rate which, when aggregated with his or her other rights to purchase~~award is an award of outstanding shares of our common stock exceeds $25,000 in fair market value per year. Unless the Plan Administrator determines otherwise, employees are also limited in making elections under the ESPP to contributing no more than 15% of their after-tax compensation to the ESPP.

~~Mandatory Retention or Sale of Stock~~

~~To facilitate compliance with applicable law, the Compensation Committee may require participants to (a) retain any shares purchased under the ESPP for~~that does not vest until a ~~designated~~specified period of time ~~or may establish other procedures to restrict transfer of such shares or (b) sell shares immediately upon purchase or within a specified period following a termination of employment.~~

~~Adjustments~~

In the event of a stock split, stock dividend, reverse stock split, extraordinary cash dividend, recapitalization, reorganization, reclassification or combination of shares, merger, consolidation, distribution, split-up, spin-off, exchange of shares, sale of assets or similar corporate transaction or event, the Compensation Committee, in the manner it deems equitable, will adjust (a) the number and class of shareshas elapsed or other securities reserved for issuance under the ESPP, (b) the number and class of shares or other securities that are subject to outstanding options, and (c) the appropriate market value and other price determinations applicable to options (including the purchase price).

~~Termination and Amendment of the ESPP~~

Our Compensation Committee generally may, at any time, terminate or amend the ESPP in any respect, except that, without approval of our stockholders, no amendment may increase the maximum number of our shares reserved under the ESPP or modify the requirementsconditions have been satisfied, as to eligibility for participation in the ESPP. No termination or amendment of the ESPP may terminate or materially and adversely affect a participant’s rights under the ESPP without such participant’s consent. Unless earlier terminateddetermined by the Compensation Committee, and which will be forfeited if the ~~ESPP~~conditions to vesting are not met. The Compensation Committee will ~~terminate when no remaining~~issue a certificate in respect to the shares ~~are available for issuance under~~of restricted stock, unless the ~~ESPP.~~Compensation Committee elects to use another system, such as book entries by the transfer agent, as evidencing ownership of such shares. In the event a certificate is issued it may be registered in the name of the grantee, and the Company will hold the certificate until the restrictions upon the award have lapsed. During the period that any restrictions apply, the transfer of stock awards is generally prohibited. Grantees have full voting rights with respect to their restricted shares. Unless the Compensation Committee determines

otherwise, all ordinary cash dividend payments or other ordinary distributions paid upon a restricted stock award will be retained by us and will be paid to the relevant grantee (without interest) when the award of restricted shares vests and will revert back to us if for any reason the restricted share upon which such dividends or other distributions were paid reverts back to us.

Restricted Stock Units

A restricted stock unit is an unfunded and unsecured obligation to issue a share of common stock (or an equivalent cash amount) to the grantee in the future. Restricted stock units become payable on terms and conditions determined by the Compensation Committee and will be settled either in cash, shares of our common stock or other securities or property, or a combination of the foregoing, as determined by the Compensation Committee.

Dividend Equivalent Rights

Dividend equivalent rights entitle the grantee to receive amounts equal to all or any of the ordinary cash dividends that are paid on the shares underlying a grant while the grant is outstanding. Dividend equivalent rights may be paid in cash, in shares of our common stock or in another form. The Compensation Committee will determine whether dividend equivalent rights will be conditioned upon the exercise of the award to which they relate (subject to compliance with Section 409A of the Code) and other terms and conditions, as determined by the Compensation Committee. No dividends may be paid unless and until an award vests.

Other Stock-Based or Cash-Based Awards

Under the 2017 Omnibus Plan, the Compensation Committee may grant other types of equity-based, equity-related or cash-based awards subject to such terms and conditions that the Compensation Committee may determine. Such awards may include the grant or offer for sale of unrestricted shares of our common stock, performance share awards and performance units settled in cash.

Performance-Based Awards

At the discretion of the Compensation Committee, other stock-based or cash-based awards may be granted in a manner which is intended to be deductible by the Company under Section 162(m) of the Code (taking into account any transition relief available thereunder). In such event, the performance-based award will be determined based on the attainment of written objective performance goals based on one or more of the Performance Criteria (as defined below) and may be measured in absolute terms or relative to historic performance or the performance of other companies or an index. The performance goal(s) must be approved by the Compensation Committee for a performance period established by the Compensation Committee (i) while the outcome for that performance period is substantially uncertain and (ii) no more than 90 days after the commencement of the performance period to which the performance goal relates or, if the performance period is less than one year, the number of ~~shares~~days which is equal to 25% of

~~common stock~~ the relevant performance period. When setting performance goals, the Compensation Committee will also prescribe a formula to determine the amount of the performance-based award that may be ~~offered~~payable upon the level of attainment of the performance goals during the performance period. Following the completion of each performance period, the Compensation Committee will have the sole discretion to determine whether the applicable performance goals have been met with respect to each individual, and if they have, will certify the amount of the applicable performance-based award. The amount of a performance-based award actually paid may be less (but not more) than the amount determined according to the formula, at the discretion of the Compensation Committee.

If performance goals are established by the Compensation Committee in connection with the grant of an award, they will be based upon performance criteria which may include one or more of the following (“Performance Criteria”): (1) return measures (including, but not limited to, total stockholder return; return on equity; return on tangible common equity; return on tier 1 common equity; return on assets or net assets; return on risk-weighted assets; and return on capital (including return on total capital or return on invested capital)); (2) revenues (including, but not limited to, total revenue; gross revenue; net revenue; revenue growth; and net sales); (3) income/earnings measures (including, but not limited to, earnings per share; earnings or loss (including earnings before or after interest, taxes, depreciation and amortization); gross income; net income after cost of capital; net interest income; non-interest income; fee income; net interest margin; operating income (before or after taxes); pre- or after-tax income or loss; pre- or after-tax operating income; net earnings; net income or loss; operating margin; gross margin; and adjusted net income); (4) expense measures (including, but not limited to, expenses; operating efficiencies; non-interest expense and operating/

efficiency ratios; and improvement in or attainment of expense levels or working capital levels (including cash and accounts receivable)); (5) balance sheet/risk management measures (including, but not limited to, loans; deposits; assets; tangible equity; charge-offs; net charge-offs; non-performing assets or loans; risk-weighted assets; classified assets; criticized assets; allowance for loans and lease losses; loan loss reserves; asset quality levels; year-end cash; investments; interest-sensitivity gap levels; regulatory compliance; satisfactory internal or external audits; financial ratings; stockholders’ equity; tier 1 capital; and liquidity); (6) cash flow measures (including, but not limited to, cash flow or cash flow per share (before or after dividends); and cash flow return on investment); (7) share price measures (including, but not limited to, share price; appreciation in and/or maintenance of share price; and market capitalization); (8) strategic objectives (including, but not limited to, market share; debt reduction; operating efficiencies; customer satisfaction; customer or household growth; employee satisfaction; research and development achievements; branding; mergers and acquisitions; succession management; people development; management retention; expense reduction initiatives; reductions in costs; risk management; regulatory compliance and achievements; and recruiting and maintaining personnel); and (9) other measures (including, but not limited to, financial ratios (including those measuring liquidity, activity, profitability or leverage); cost of capital or assets under management; and financing and other capital raising transactions). Any of the above criteria may be used with or without adjustment for extraordinary items or nonrecurring items, and to the extent permitted under Section 162(m) of the Code (taking into account any transition relief available thereunder), the Compensation Committee may provide for objectively determinable adjustments, modifications or amendments, as determined in accordance with GAAP, to any of the Performance Criteria for one or more of the items of gain, loss, profit or expense.

Adjustments

In connection with 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, the Compensation Committee will make adjustments as it deems appropriate in (i) the maximum number of shares of our common stock reserved for issuance as grants, (ii) the maximum number of stock options, SARs or awards intended to qualify as “performance-based compensation” that any individual participating in the 2017 Omnibus Plan may be granted in any fiscal year, (iii) the number and kind of shares covered by outstanding grants, (iv) the kind of shares that may be issued under the 2017 Omnibus Plan and (v) the terms of any outstanding stock awards, including exercise or strike price, if applicable.

Amendment; Termination

Our Board of Directors may amend or terminate the 2017 Omnibus Plan at any time, provided that no such amendment may materially adversely impair the rights of a grantee of an award without the grantee’s consent. Our stockholders must approve any amendment to the extent required to comply with the Code, applicable laws or applicable stock exchange requirements. Unless terminated sooner by our Board of Directors or extended with stockholder approval, the 2017 Omnibus Plan will terminate on the day immediately preceding the tenth anniversary of the date on which our stockholder approved the 2017 Omnibus Plan, but any outstanding award will remain in effect until the underlying shares are delivered or the award lapses.

Change in Control

Unless the Compensation Committee determines otherwise, or as otherwise provided in the applicable award agreement, (i) in the case of a grantee other than a non-employee director, if such grantee’s employment is terminated by us without “cause” (as defined in the 2017 Omnibus Plan) or the participant resigns his or her employment for “good reason” (as defined in the 2017 Omnibus Plan), in either case, on or within two years after a “change in control” (as defined in the 2017 Omnibus Plan), (A) all outstanding awards will become fully vested (including 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) in the case of 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” (as defined in the 2017 Omnibus Plan), 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 will 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.

number of shares available for issuance under the plan

In the event of a change in control, the Compensation Committee may also (i) provide for the assumption of or the issuance of substitute awards, (ii) provide that for a period of at least 20 days prior to the change in control, stock options or SARs that would not otherwise become exercisable prior to a change in control will be exercisable as to all shares of common stock, as the case may be, subject thereto and that any stock options or SARs not exercised prior to the consummation of the change in control will terminate and be of no further force or effect as of the consummation of the change in control, (iii) modify the terms of such awards to add events or conditions (including the termination of employment within a specified period after a change in control) upon which the vesting of such awards 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 Compensation Committee) after closing or (v) settle awards for an amount of cash or securities equal to their value (in the case of stock options and SARs that are settled in cash, the value of such awards will be equal to their in-the-money spread value, if any, of such awards, as determine in the sole discretion of the Compensation Committee). 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 compensation committee will determine if awards settled pursuant to item (v) above are (a) valued at closing taking into account such contingent consideration (with the value determined by the Compensation Committee in its sole discretion) or (b) entitled to a share of such contingent consideration.

In general terms, except in connection with any initial public offering and except as expressly defined in an award agreement, a change in control under the 2017 Omnibus Plan occurs if following the completion of this offering:

•

during any period of not more than 36 months, individuals who constitute the Board of Directors as of the beginning of the period whose appointment or election is endorsed by two-thirds of the incumbent directors no longer constitute a majority of the Board;

•

a person, other than MBG Investors I, L.P. or any of its direct or indirect subsidiaries, becomes a beneficial owner, directly or indirectly, of our capital stock representing 50% of the voting power of our outstanding capital stock;

•

we merge into another entity, unless (i) the business combination is with MBG Investors I, L.P. or any of its direct or indirect subsidiaries or (ii) (a) more than 50% of the combined voting power of the merged entity or its parent is represented by our voting securities that were outstanding immediately prior to the merger, (b) the board of directors prior to the merger constitutes at least 50% of the board of the merged entity or its parent following the merger and (c) no person is or becomes the beneficial owner of 50% or more of the combined voting power of the outstanding capital stock eligible to elect directors of the merged entity or its parent;

•

we sell or dispose of all or substantially all of our assets (other than to MBG Investors I, L.P. or any of its direct or indirect subsidiaries); or

•

we are liquidated or dissolved.

Clawback

All awards under the 2017 Omnibus Plan will be subject to any applicable law respecting recapture of compensation or such Company Compensation Clawback policy as may be in effect at the time of grant.

New Plan Benefits

Because grants under the 2017 Omnibus Plan are discretionary, the Company cannot now determine the number of awards that will be granted in the future to any particular executive officer, to all executive officers as a group or to non-executive officer employees or directors as a group. The number of such awards will be determined by the Compensation Committee from time to time in accordance with the terms of the 2017 Omnibus Plan, as amended.

	Proposal 3			The board recommends a vote FOR this proposal
	Approval of, on an advisory (non-binding) basis, the compensation of the Company’s named executive officers as described in this Proxy Statement
	During the fiscal year ended December 31, 2022, we exited “emerging growth company” status as defined in the Jumpstart Our Business Startups Act. As such, our stockholders will have their first opportunity to cast a non-binding advisory vote to approve our executive compensation at the Annual Meeting in 2023 known as “Say-on-Pay”. We have historically been regularly connected to our largest investors. As we continue to evolve, we intend to broaden our stockholder engagement efforts and facilitate open and ongoing dialogues with key stakeholders to help ensure that we have a regular pulse on investor perspectives. In the future, we will consider the feedback we receive from our major stockholders as well as the outcome of Say-on-Pay votes when making compensation decisions regarding our named executive officers (“NEOs”). Following the Say-on-Pay vote at the Annual Meeting and depending on the outcome of Proposal No. 4 (regarding the frequency of future Say-on-Pay votes), our next Say-on-Pay vote is expected to occur at our 2024 annual meeting of stockholders. As required pursuant to Section 14A of the Exchange Act, we are providing stockholders with an opportunity to vote to approve, on an advisory basis, the compensation of our named executive officers as disclosed in this Proxy Statement. As discussed above, although this vote is advisory and thus non-binding, the Board and the Compensation Committee value the opinions of our stockholders and will consider the outcome of this Say-on-Pay vote when evaluating our compensation philosophy, policies and practices.

Executive Compensation

The Company believes that its compensation policies and procedures, which are reviewed and approved by the Compensation Committee, encourage a culture of pay-for-performance and are strongly aligned with the long-term interests of stockholders. As more fully set forth under “Executive Compensation—Compensation Discussion & Analysis,” the Compensation Committee has taken a number of actions in recent years to further strengthen the Company’s compensation philosophy and objectives and the percentage of the compensation of senior executives which is “at risk.” As always, the Compensation Committee will continue to review all elements of the executive compensation program and take any steps it deems necessary to continue to fulfill the objectives of the program.

Stockholders are encouraged to carefully review the “Executive Compensation—Compensation Discussion & Analysis” section of this Proxy Statement for a detailed discussion of the Company’s executive compensation program. Because this stockholder vote is advisory, it will not be binding on the Board or the Compensation Committee. However, the Compensation Committee will take into account the outcome of the vote when considering future executive compensation arrangements.

The Board has authorized a stockholder vote on the compensation of the Company’s named executive officers as reflected in the Compensation Discussion & Analysis, including the disclosures regarding named executive officers compensation provided in the various tables included in this Proxy Statement, the accompanying narrative disclosures and the other compensation information provided in this Proxy Statement. This proposal, commonly known as a Say-on-Pay proposal, gives the Company’s stockholders the opportunity to endorse or not endorse the Company’s executive pay program and policies through the following resolution:

“Resolved, that the stockholders of Byline Bancorp, Inc. approve, on a non-binding advisory basis, the compensation of the named executive officers, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the compensation tables and narrative discussion in this Proxy Statement for the 2023 Annual Meeting of Stockholders.”

TABLE OF CONTENTS

	Proposal 4			The board recommends a vote FOR this proposal
	Approval of, on an advisory (non-binding) basis, the frequency of future Stockholder advisory votes to approve the compensation of the Company’s named executive officers
	As required by Section 14A of the Exchange Act, every six years, the Company will provide stockholders with an opportunity to vote to approve, on an advisory basis, the frequency of the Say-on-Pay vote as described in Proposal No. 3. We are asking stockholders whether future Say-on-Pay votes should be held every year.

Frequency of Say-on-Pay Advisory Vote

After careful consideration, our Board recommends that stockholders vote “FOR ONE YEAR” as the frequency of future Say-on-Pay votes for a number of reasons, including the following:

•

An annual Say-on-Pay vote allows us to obtain stockholder input on our executive compensation program on a more consistent basis which aligns more closely with our objective to engage in regular dialogue with our stockholders on corporate governance matters, including our executive compensation philosophy, policies and practices;

•

A one-year frequency provides the highest level of accountability and communication by enabling the Say-on-Pay vote to correspond with the most recent executive compensation information presented in our proxy statement for the annual meeting;

•

A longer approach may make it more difficult for the Compensation Committee to understand and respond to the voting results because it may be unclear whether the stockholder vote pertains to the most recent executive compensation information presented in our proxy statement or to pay practices from the previous two years or both; and

•

Holding Say-on-Pay votes annually reflects sound corporate governance principles and is consistent with a majority of institutional investor policies.

We are asking our stockholders to vote for a ONE YEAR frequency when voting in response to the following resolution at the Annual Meeting:

“Resolved, that the frequency option of every one year, two years or three years, that receives the highest number of votes cast, will be determined to be the recommended frequency with which the Company is to hold a stockholder vote to approve the compensation of the named executive officers, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the compensation tables and narrative discussion in the proxy statement for the annual meeting of stockholders.”

Report of the Audit Committee

The Audit Committee of the Board of Directors is responsible for providing independent, objective oversight of the Company’s accounting functions and internal controls and is composed of directors that are “independent” as defined under the NYSE corporate governance listing standards and Rule 10A-3 of the Exchange Act. The Audit Committee operates under a written charter approved by the Board of Directors and held 1415 meetings during fiscal year ~~2021.~~2022. A copy of the charter is available on our website at www.bylinebancorp.com under the ~~“Governance~~“Corporate Governance Documents” tab.

Management is responsible for the Company’s internal control over financial reporting, disclosure controls and procedures and the financial reporting process. The independent registered public accounting firm is responsible for performing an independent audit of our consolidated financial statements in accordance with Public Company Accounting Oversight Board (PCAOB) standards and to issue reports thereon. The Audit Committee’s responsibility is to monitor and oversee these processes, including the activities of the Company’s internal audit function. The Audit Committee has established a mechanism to receive, retain and process complaints on auditing, accounting and internal control issues, including the confidential, anonymous submission by employees and others of concerns on questionable accounting and auditing matters.

In connection with these responsibilities, the Audit Committee met with management and the independent registered public accounting firm to review and discuss the ~~2021~~2022 audited consolidated financial statements. The Audit Committee also discussed with the independent registered public accounting firm the matters required by the applicable requirements of the PCAOB ~~Auditing Standard No. 1301, Communications with Audit Committees.~~and the SEC. In addition, the Audit Committee received the written disclosures and letter from the independent registered public accounting firm required by applicable requirements of the PCAOB regarding the independent accountant’s communications with the Audit Committee concerning independence, and the Audit Committee has discussed with the independent registered public accounting firm its independence from the Company and its management.

Based upon the Audit Committee’s discussions with management and the independent registered public accounting firm, and the Audit Committee’s review of the representations of management and the independent registered public accounting firm, the Audit Committee recommended that the Board of Directors include Byline’s ~~2021~~2022 audited consolidated financial statements in our Annual Report on Form 10-K for fiscal ~~2021~~2022 filed with the SEC.

We operate a compensation philosophy based on key principles that guide the development of our compensation programs, practices, and policies. These key principles include, but are not limited to, the following:

Align compensation programs, practices, policies and decisions with stockholder and other stakeholder interests.

~~Narrative Disclosure~~2.

Reinforce a business-oriented culture that rewards executives for results consistent with:

Performance against business goals and objectives

Our executive compensation program is designed to ~~Summary~~be:

Competitively Positioned: The successful operation of the bank requires an experienced and talented senior management team. To hire and retain the required level of talent, the bank’s executive compensation program must be competitive with respect to both total compensation and each individual compensation component.

•

Performance-Driven and Stockholder-Aligned: The compensation program should encourage and reward excellent performance from the senior management team. The Bank will develop a market-competitive total compensation package that drives the achievement of key business objectives, is aligned with the institution’s overall performance, and is tied to the attainment of individual and corporate performance objectives. The compensation program will maintain the appropriate balance between base compensation and short- and long-term incentive opportunities. Compensation ~~Table~~levels are linked to the long-term performance and sustainability of the Bank.

•

Responsibly Governed: Decisions about compensation should be guided by best-practice governance standards and rigorous processes that encourage prudent decision-making. Controls are in place for the proper administration and oversight of the compensation programs. Employees should balance potential outcomes with appropriate risk-taking. The Company expects employees to act in a manner consistent with the highest ethical standards. Results obtained through deceptive tactics or inconsistent with our values and culture are not rewarded. We have incorporated this thinking into our compensation programs, practices, and policies. These include but are not limited to claw backs (i.e., the recoupment of past incentive compensation due to error or misrepresentation), discretionary downward adjustments to incentive compensation, employment decisions, and disciplinary actions.

The Decision-Making Process

The Role of the Compensation Committee. The Compensation Committee sets and administers the policies that govern our executive compensation programs and is responsible for discharging the Board’s responsibilities relating to compensation of our executive officers and directors. The Compensation Committee has adopted a written charter that, among other things, specifies the scope of its rights and responsibilities. A copy of the Committee’s charter is available on our website at www.bylinebancorp.com under the “Corporate Governance Documents” tab. The Compensation Committee is composed solely of members who satisfy the applicable independence requirements of the NYSE as they apply to members of compensation committees.

The Role of Management. Our Chief Executive Officer, President, and Chief Human Resources Officer, working with internal resources as well as with our Compensation Committee’s compensation consultant, review our executive compensation program on an annual basis and make recommendations as to the type and amount of compensation based on its review of peer group and other market data, individual performance and other factors. Our Chief Executive Officer and President make recommendations to our Compensation Committee regarding the compensation of our executives other than themselves based on these same factors. Our Chief Executive Officer, President, and Chief Human Resources Officer typically attend meetings of our Compensation Committee but do not participate in any discussions regarding their own compensation.

The Role of the Independent Compensation Consultant. In 2022, the Compensation Committee retained Pearl Meyer primarily to assist the Compensation Committee in determining and structuring executive compensation and

Executive Compensation

to assess the market competitiveness of the Company’s executive compensation program. The Compensation Committee has annually engaged Pearl Meyer for these and related services since 2014. With respect to any advice provided to the Committee by Pearl Meyer, the Compensation Committee received a letter from Pearl Meyer addressing factors relevant to SEC and NYSE rules regarding independence and conflicts of interest. After considering the information provided by Pearl Meyer and other factors, no conflicts of interest with respect to Pearl Meyer were identified by the Compensation Committee, and the Compensation Committee concluded that Pearl Meyer was an independent consultant.

Compensation Benchmarking and Decisions

The Compensation Committee’s objective is to set a competitive level of total compensation for each NEO as compared with executive officers in similar positions at peer companies. For purposes of benchmarking 2022 compensation levels, in conjunction with the recommendation of Pearl Meyer, the Compensation Committee considered publicly available data for a group of peer companies listed below along with industry-specific survey data where appropriate. Selection criteria used to establish the competitive market for the NEOs, generally include:

•

Industry: Commercial banks and savings banks/thrifts listed on a national exchange and located in the contiguous U.S.

•

Size: Banks with assets ranging from approximately 0.5x — 2.5x our asset size (~$5 billion — $13 billion).

•

Loan Mix: Banks with a minimum of 40% of their loan portfolio in commercial business

•

Asset Growth: Banks with a minimum of 5% asset growth on a three-year annualized basis.

•

Additional refinement: Excluded banks due to acquisition/merger activity, business model, etc.

Based on the analysis, a peer group of 24 companies used in benchmarking the 2022 executive compensation included the following:


	1st Source Corporation			Preferred Bank
	Allegiance Bancshares, Inc.			Provident Financial Services, Inc.
	CrossFirst Bankshares, Inc.			QCR Holdings, Inc.

Executive Compensation Program in Detail

Elements of Pay: Total Direct Compensation

To support our philosophy and achieve our objectives, the Compensation Committee analyzes each of the following elements of compensation against comparative market data, and generally seeks to position each element around the market median, while differentiating individual compensation based on experience, role, position, individual performance, and other factors.

Pay Element	How It’s Paid	Purpose
Base Salary	Cash (Fixed)	Provide a competitive base salary rate relative to similar positions in the market and enable the Company to attract and retain critical executive talent.
Short-Term Incentives	Cash (Variable)	Tie a significant portion of our executives’ cash compensation opportunities to the attainment of performance goals that we believe will help us attain short- and long-term business objectives.
Long-Term Incentives	Equity (Variable)	Provide incentives for executive officers to execute on longer-term financial goals that drive the creation of stockholder value and also support the Company’s leadership retention objectives.

Pay Mix

The charts below show the target annual total direct compensation of our CEO and our other NEOs for fiscal year 2022. These charts illustrate that a majority of NEO total direct compensation is variable (62.26% for our CEO and an average of 50.71% for our other NEOs).

2022 Corporate Performance Measures

Seventy (70) percent of a named executive officer’s annual incentive award is based on achievement against our corporate performance scorecard, except for Mr. Abraham for whom 100% of the annual incentive award is based on the Small Business Capital business unit scorecard. Corporate performance targets are set based on our approved annual corporate plan, which represents our expectations for the year, and are assessed against the scorecard at the end of the fiscal year. The 2022 scorecard, including metric weightings, performance targets, and actual results, is outlined below. To receive any payment under the plan, the Company must achieve at least 75% of the budgeted Net Income. For 2022, we exceeded that threshold by achieving 120% of our budgeted Net Income.

~~Long-term incentive~~

The named executive officers participate in a ~~Long-term~~Long-Term Incentive Program (“LTIP”) that provides a variable pay opportunity through a combination of performance shares and restricted shares. The program is designed to reinforce the long-term alignment of the Company’s executives with the interests of our stockholders. Performance shares are intended to strengthen our pay-for-performance philosophy while time-vested restricted shares are granted to promote share ownership and executive retention. Below is a summary of the 2022 LTIP:

Award Type	Weighting	Design At-a-Glance
Performance Shares	50%	Performance shares align executive pay with achievement of financial metrics that are the most impactful to stockholders. Vesting is dependent on the achievement of specified goals and is measured at the end of a three-year performance period. The 2022 performance shares are tied to Byline’s three-year (2022-2024) Return on Average Assets (ROAA) as compared to a custom peer group of approximately 100 publicly traded bank holding companies ranging in asset size from 50% to 200% of Byline’s total assets. Performance will be measured cumulatively at the end of the performance period. Threshold, target, and superior performance levels are set at the 25th, 50th and 75th percentiles of the peer index, respectively. ROAA is defined as net income as a percent of average assets. Our named executive officers may earn 25% of their target opportunity for threshold-level performance, up to 100% of their target opportunity, and up to 150% of their target opportunity for superior-level performance. Amounts between threshold and superior are interpolated to reward incremental achievement and no amounts are paid with respect to a particular performance metric if actual results are below threshold.
Time-Based Restricted Shares	50%	Time-based restricted shares vest equally over three years on the anniversary date of the grant. Awards vest automatically upon 1) death, 2) termination of employment due to disability and 3) termination following a change-in-control.

The Board of Directors and the Compensation Committee are actively monitoring the effects of the COVID-19 pandemic on the economy, the equity trading markets (including, in particular, the value of equity securities of financial institutions) and our operations and future results. In light of these developments, the Compensation Committee will evaluate the actual and potential effects on our business results, financial condition and stockholder value. Performance goals and the incentives associated with our executive and management compensation and incentive plans could be modified, and the Board of Directors maintain discretion to adjust plans and award payouts to appropriately reflect performance. Any material changes will be disclosed in accordance with applicable disclosure obligations.

Executive Compensation

Compensation Clawback Policy

We have a clawback policy that, in the event of a restatement of our financial statements to correct a material non-compliance with any applicable financial reporting requirement, allows the Compensation Committee to seek recovery or forfeiture from any executive officer. This recovery or forfeiture would include the portion of incentive compensation that was received by or vested in the executive officer during the three-year period prior to the determination that a restatement was required and that would not have been earned had performance been measured on the basis of the restated results, if the Compensation Committee determines that the executive engaged in intentional fraud or gross misconduct or was otherwise directly or indirectly responsible for the restatement. The Company will comply with necessary guidelines as they are issued and applicable.

Hedging and Pledging Policy

Consistent with our Board’s belief that significant stock ownership by directors and executive officers strengthens the alignment of their interests with our stockholders and promotes our long-term business objectives, we do not permit our directors and executive officers to enter into hedging and monetization transactions or to engage in short sale transactions in the Company’s securities. We believe that such transactions can mitigate or eliminate the economic risk of ownership and disincentivize such individuals from seeking to improve the Company’s performance and consequently impair their alignment with our stockholders’ interests.

We also do not permit our directors and executive officers to enter into pledge arrangements involving their shares of our common stock. We believe such arrangements present a risk that the individual could be pressured or forced to sell our stock to meet loan requirements, which we believe would be inconsistent with our belief in aligning their interests with long-term stockholder interests, and potentially could cause us reputational harm and violate internal policies regarding transacting in our stock when such person is aware of material nonpublic information or otherwise prohibited from trading in our stock.

A copy of the hedging and pledging policy is available on our website at www.bylinebancorp.com under the “Corporate Governance Documents” tab.

Employment Agreements

Our use of employment agreements is limited to only a select number of our Executive Officers. We currently have agreements with our CEO (Mr. Herencia), President (Mr. Paracchini), CFO (Mr. Bell), and our President of Small Business Capital (Mr. Abraham). Each agreement generally describes the position and duties of each NEO, provides for a specified term of employment, describes base salary, bonus opportunity and other benefits and perquisites to which the executive officer is entitled, if any, sets forth the duties and obligations of each party in the event of a termination of employment prior to expiration of the employment term, and provides us with a measure of protection by obligating the NEO to abide by the terms of restrictive covenants during the terms of his employment and thereafter for a specified period of time.

Our obligation to pay any severance under each of the employment agreements is conditioned on the execution by the NEO of a general release and waiver of any and all claims with respect to their employment with the Company.

The terms of these agreements were negotiated and determined with consideration of the best interests of the Company and our stockholders. In attracting and securing a talented team of executive officers, we believe we have positioned the Company to successfully execute our growth strategy and vision.

Severance and Change in Control

Mr. Ptacin has a change in control agreement that outlines the terms of his change in control severance. We believe these arrangements are consistent with peer practices and provide an appropriate level of compensation to our executive officers if their employment is terminated as a result of a change in control.

Executive Perquisites and Other Benefits

We have a limited amount of perquisites offered to NEOs. These include auto allowances for Messrs. Herencia, Abraham and Ptacin, as well as club dues for Messrs. Herencia, Paracchini, and Ptacin. Additional executive life insurance policies were paid in 2022 for Messrs. Herencia, Paracchini and Ms. Corby (prior to termination of her

employment in September, 2022). Moving forward, policies will be paid for Messrs. Herencia, Paracchini and Bell. Other life insurance premiums paid for the benefit of each of our named executive officers are consistent with company policyfor all Byline employees.

The NEOs are eligible to participate in the same benefit plans designed for all of our full-time employees, including health, dental, vision, disability and basic group life insurance coverage. We also provide our employees, including our NEOs, with various retirement benefits. Our retirement plans are designed to assist our employees in planning for retirement and securing appropriate levels of income during retirement. The purpose of our retirement plans is to attract and retain qualified employees, including executives, by offering benefit plans similar to those typically offered by our competitors.

The Bank has adopted and established a Death Benefit Only Plan in order to provide participating employees with a death benefit of $200,000 to their named beneficiaries in the event of an employee’s death, while employed by the Bank. NEOs and other executives are participants in this Plan. The Bank is both the named fiduciary and plan administrator of the Plan.

Compensation Risk Management

Our compensation plans are evaluated annually by our risk management professionals and our Compensation Committee, as part of its effort to ensure our compensation plans do not encourage imprudent risk taking. We employ a variety of performance metrics to deter excessive risk-taking by not including any incentive focused on a single performance goal. We have built in appropriate levels of discretion to adjust incentive payouts if results are not aligned with credit quality, regulatory compliance, or leading indicators of future financial results.

Impact of Tax and Accounting

We regularly consider the various tax and accounting implications of our compensation plans. When determining the value of long-term incentives and equity grants to executives and employees, the compensation costs associated with the grants are reviewed, as required by FASB ASC Topic 718.

Compensation Committee Report

The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis with Byline’s management and the Board’s outside compensation consultant. Based on the review and discussions, the Compensation Committee has recommended to the Board of Directors that the Compensation Discussion and Analysis be included in the Company’s 2022 Annual Report on Form 10-K and the Company’s 2023 proxy statement.

(1)

The amounts set forth in the “Salary” column reflect base salary earned in each fiscal year including amounts deferred under the Defined Contribution Plan.

(2)

The amounts set forth in the “Stock Awards” column represent the grant date fair value of shares of restricted stock determined in accordance with FASB ASC Topic 718 that were awarded in 2020, 2021, and 2022. Assumptions used in the calculation of the grant date fair value are included in Note 18, 19 and 18 to the Company’s audited financial statements for each year shown included in the Company’s Annual Reports on Form 10-K filed with the SEC. For Messrs. Paracchini, Bell, and Ptacin, and Ms. Corby, 50% of these shares are subject to time vesting, equally over three years from the grant date; the remaining 50% are performance-based, based on the achievement of performance goals over a three-year period beginning January 1 of the year granted. Any earned performance shares vest in full on the third anniversary of the grant date. For Mr. Herencia, the 2022 award was split equally between time and performance-based shares. Mr. Herencia’s 2021 shares will vest one-third on each of the following dates: December 31, 2021, December 30, 2022, and December 29, 2023. For Mr. Abraham, the shares are subject to time vesting, equally over three years from the grant date.

Values disclosed for 2022 assume target level of performance with respect to the performance-based portion of the restricted stock awards. Assuming the highest level of performance for the performance-based portion of the restricted stock granted in 2022, the value of such awards would be as follows: Mr. Herencia — $525,955; Mr. Paracchini — $276,753; Mr. Bell — $57,608; and Mr. Ptacin — $100,490. Ms. Corby resigned from the Company effective September 2, 2022, and forfeited her entire 2022 award in accordance with its terms.

(1)

The amounts set forth in the “Estimated Future Payouts Under Non-Equity Incentive Plan Awards” columns reflect the threshold, target, and maximum payouts for performance for the cash awards under the Executive Incentive Plan. Payments are triggered when the bank meets 75% of its budgeted net income (after taxes) for the plan year. At threshold, payments are based on the company performance portion of the scorecard assuming no individual performance. The maximum payout is 200% of the participant’s incentive target for the Plan year.

(2)

The amounts set forth in the “Estimated Future Payouts Under Performance Share Equity Incentive Plan Awards” columns reflect the number of shares earned based on Byline’s average return on average assets over the three-year period starting on January 1, 2022, and ending December 31, 2024, weighted equally each year (33.33%). ROAA is Byline’s Adjusted ROAA (per SEC filings) against Peer Group ROAA. Under the award, 25% of the shares will be earned at threshold and 25th percentile performance, 100% will be earned at target and 50th percentile performance, and up to 150% of the shares will be earned at above target and 75th percentile performance. Performance between threshold and target, and between target and maximum, will be awarded using straight line interpolation.

(3)

The amounts set forth in the “All Other Stock Awards: Number of Shares “ column reflect the number of time-based restricted shares granted in 2022 that vest in equal annual increments (33.33%) over three-years subject to continued employment.

(4)

The amounts set forth in the “Grant Date Fair Value of Stock Awards” column reflect the value of the restricted share awards granted in 2022. This value represents the sum of the performance share awards at target and the time-based restricted share awards multiplied by the grant date fair value of $26.97 per share.

For purposes of estimating the value of accelerated vesting of equity awards, we have assumed a price per share of our common stock of $22.97 based on the closing price of our common stock on December 30, 2022 (the last trading day of the year).

The determine the median employee, a list of all active full- and part-time employees as of December 31, 2022, excluding the Executive Chairman/CEO, was prepared with the corresponding annual total W-2 compensation as reflected in our payroll records. A total of 991 employees were included. Compensation was annualized for any individual not employed for the full calendar year of 2022. Annual W-2 compensation was ranked from lowest to highest, and the median employee was selected from the list.

Mr. Herencia had 2022 total compensation of $2,264,159 as reflected in the 2022 Summary Compensation Table included in this Proxy Statement. The median employee annual total compensation for 2022, using the same methodology, was $70,628. As a result, the CEO pay ratio is 32:1.

This pay ratio is a reasonable estimate calculated in a manner consistent with SEC rules based on our payroll and employment records and the methodology described above. Because the SEC rules for identifying the median

TABLE OF CONTENTS

Certain Relationships and Related Transactions

Byline or one of its subsidiaries may occasionally enter into transactions with certain “related persons”. Related persons include our executive officers, directors, 5% or more beneficial owners of our common stock, immediate family members of these persons and entities in which one of these persons has a direct or indirect material interest. We generally refer to transactions with these related persons as “related party transactions”.

Related Party Transaction Policy

Our Board of Directors has adopted a written policy governing the review and approval of transactions with related parties that will or may be expected to exceed $120,000 in any fiscal year. The policy provides that related party transactions are reviewed and, if deemed appropriate, approved or ratified by our Audit Committee. Upon determination by our Audit Committee that a transaction requires review under the policy, the material facts are required to be presented to the Audit Committee. In determining whether or not to approve a related party transaction, our Audit Committee will take into account, among other relevant factors, whether the related party transaction is in our best interests, whether it involves a conflict of interest and the commercial reasonableness of the transaction. In the event that we become aware of a related party transaction that was not approved under the policy before it was entered into, our Audit Committee will review such transaction as promptly as reasonably practical and will take such course of action as may be deemed appropriate under the circumstances. In the event a member of our Audit Committee is not disinterested with respect to the related party transaction under review, that member may not participate in the review, approval or ratification of that related party transaction.

Certain decisions and transactions are not subject to the related party transaction approval policy, including: (i) decisions on compensation or benefits relating to directors or executive officers and (ii) indebtedness to us in the ordinary course of business, on substantially the same terms, including interest rate and collateral, as those prevailing at the time for comparable loans with persons not related to us and not presenting more than the normal risk of collectability or other unfavorable features.

A copy of the related party transaction policy is available on our website at www.bylinebancorp.com under the ~~“Governance~~“Corporate Governance Documents” tab.

Related Party Transactions

In the ordinary course of our business, we have engaged and expect to continue engaging through our bank in ordinary banking transactions with our directors, executive officers, their immediate family members and companies in which they may have a 5% or more beneficial ownership interest, including loans to such persons. Any such loan was made on substantially the same terms, including interest rates and collateral, as those prevailing at the time such loan was made as loans made to persons who were not related to us. These loans do not involve more than the normal credit collection risk and do not present any other unfavorable features to us.

Foreign National Commitments

Certain of our stockholders are foreign nationals, and we and certain of these foreign national stockholders have entered into commitments with the Federal Reserve that restrict our ability to engage in certain business transactions without the consent of the Federal Reserve. In particular, subject to certain limited exceptions, we are not permitted to engage in or be a party to any business transaction or relationship with a company that is controlled by these foreign national stockholders or by their immediate families. In addition, Byline Bank is not permitted to engage in or be a party to any extension of credit, as defined in the Federal Reserve’s Regulation O, to these foreign national stockholders, their immediate families or any company controlled by these foreign national stockholders. Byline Bank is also not permitted to engage in or be a party to any covered transaction, as defined in the Federal Reserve Act and the Federal Reserve’s Regulation W, with any company that is controlled by these foreign national stockholders.

Stockholders should refer to the full text of our advance notice provisions contained in Section 1.12 of our Amended and Restated By-Laws. In addition, any stockholder who intends to solicit proxies in support of director nominees other than Byline’s nominees also must comply with the additional requirements of Rule 14a-19(b) under the Exchange Act.

Written notice of stockholder proposals to be brought at Byline’s 2023 Annual Meeting of Stockholders in accordance with the above procedures must be delivered to Byline’s secretary no earlier than February 7, ~~2023,~~2024, and no later than March ~~9, 2023,~~8, 2024, unless an Other Meeting Date occurs with respect to the ~~2023~~2024 Annual Meeting, in which case the notice delivery requirements will be as set forth above with respect to meetings with Other Meeting Dates.

In lieu of the foregoing notice procedures, stockholders seeking to submit a proposal for inclusion in our proxy statement for the ~~2023~~2024 Annual Meeting must follow the procedures and meet the other requirements outlined in Rule 14a-8 of the Exchange Act, and we must receive such proposal at our principal executive offices on or before December 26, ~~2022.~~2023.

Delivery of Documents to Stockholders Sharing an Address

The SEC’s proxy rules permit companies and intermediaries to satisfy delivery requirements for proxy statements with respect to two or more stockholders sharing an address by delivering a single proxy statement and annual report with separate proxy cards to those stockholders. This method of delivery, often referred to as “householding,” reduces the amount of duplicate information that stockholders receive and lowers printing and mailing costs for companies. We are not householding materials for our registered stockholders in connection with the Annual Meeting; however, we understand that certain intermediaries will household our proxy materials.

If a brokerage, bank or other nominee holds your shares, this means that only one Proxy Statement and annual report will be delivered to multiple stockholders sharing an address. Any stockholder residing at such an address who would like to receive an individual copy of the materials, or who is receiving multiple copies of our Proxy Statement and Annual Report and would prefer to receive a single copy in the future, may contact Broadridge, Householding Department by mail at 51 Mercedes Way, Edgewood, New York 11717 or by telephone at (866) 540-7095. Be sure to include your name, the name of your brokerage firm and your account number.

Other Matters

Upon receipt of a written request addressed to our Corporate Secretary at Byline Bancorp, Inc., 180 North LaSalle Street, Suite 300, Chicago, Illinois 60601 from any person solicited herein, we will provide, at no cost, a copy of our ~~2021~~2022 Annual Report on Form 10-K as filed with the SEC.

Our Board of Directors does not know of any matter to be brought before the Annual Meeting other than the matters set forth in the Notice of Annual Meeting of Stockholders and matters incident to the conduct of the Annual Meeting. If any other matter should properly come before the Annual Meeting, the persons named in the enclosed proxy card will have discretionary authority to vote all proxies with respect thereto in accordance with their best judgment.

~~(b)~~

which permits the Eligible Employee’s right to purchase stock under all employee stock purchase plans of the Company to accrue at a rate which exceeds $25,000 in fair market value of the stock (determined at the time such option is granted) for each calendar year in which such option is outstanding; or

~~(c)~~

~~ARTICLE IV – OFFERINGS~~

~~4.01.~~

~~Offerings~~

The Plan will be implemented by Offerings beginning on the first January 1 or July 1 that occurs after the Effective Date and, unless determined otherwise by the Committee, on each January 1 or July 1 that occurs thereafter. Without limiting the generality of the foregoing, the Committee may establish an Offering prior to the first January 1 or July 1 that occurs after the Effective Date, which may have a period of less than six months.

Participants may subscribe to any Offering for which they are eligible by entering a Subscription during the Enrollment Period for such Offering in such manner as the Committee may prescribe (which may include enrollment by submitting forms, by voice response, internet access or other electronic means).

A Subscription that is in effect on an Offering End Date will automatically be deemed to be a Subscription for the Offering that commences immediately following such Offering End Date, provided that the Participant is still an Eligible Employee and has not withdrawn the Subscription, unless otherwise determined by the Committee. If a Participant purchases shares that cause the Participant to reach the limitation set forth in Section 3.03(b) or Section 3.03(c), the Participant’s Subscription will automatically be suspended for the duration of the calendar year and will resume at the beginning of the next calendar year, provided that the Participant is still an Eligible Employee and has not withdrawn the Subscription, unless otherwise determined by the Committee. Under the foregoing automatic enrollment provisions, payroll deductions or contributions will continue at the level in effect immediately prior to the new Offering Commencement Date, unless changed in advance by the Participant in accordance with Section 5.03.

~~Purchase Price~~

The purchase price per share of Stock under each Offering shall be 85% of the closing price of the Stock on the Purchase Date. Notwithstanding the foregoing, the Committee may determine with respect to any Offering either that (i) the purchase price shall be a different percentage, which shall not be less than 85%, of the closing price of the Stock on the Purchase Date, or (ii) the purchase price shall be a percentage (which shall not be less than 85%) of the lower of the closing price of the Stock on the Offering Commencement Date or the Purchase Date. If the Stock is not traded on the principal securities exchange on which the Stock is admitted to trade on any of the aforesaid dates for which closing prices of the stock are to be determined, then reference shall be made to the next preceding date on which the Stock was so traded. Such determination shall be made and communicated to Eligible Employees during the Enrollment Period for such Offering.

~~Such purchase price may only be paid with accumulated payroll deductions in accordance with Article V.~~

~~5.02.~~

~~Participant’s Account~~

All payroll deductions made with respect to a Participant shall be credited to his or her account under the Plan. A Participant may not make any separate cash payment into such accounts. No interest will accrue or be paid on any amount withheld from a Participant’s pay under the Plan or credited to the Participant’s account. Except as otherwise provided in this Section 5.02, Section 6.01 or Section 8.01, or as provided upon termination of the Plan, all amounts in a Participant’s account will be used to purchase Stock and no cash refunds shall be made from such account. Any amounts remaining in a Participant’s account with respect to an Offering due to the limitations of Section 3.03 shall be returned to the Participant without interest and will not be used to purchase shares with respect to any other Offering under the Plan.

~~5.03.~~

During an Offering, a Participant may change his or her level of payroll deduction or contribution with respect to such Offering within the limits described in Section 5.01 in accordance with procedures established by the Committee (including, without limitation, rules relating to the frequency of such changes or prohibiting changes under certain circumstances); provided, however, if the Participant reduces his or her payroll deductions or contributions to zero, it shall be deemed to be a withdrawal of the Subscription and the Participant may not thereafter participate in such Offering but must wait until the next Offering to resubscribe to the Plan. Any increases or decreases in the level of payroll deductions or contributions shall be effective as soon as administratively practicable thereafter.

~~ARTICLE VI – EXERCISE OF OPTION~~

~~6.01.~~

~~Automatic Exercise~~

A Participant’s option for the purchase of Stock with respect to any Offering will be automatically exercised on each Purchase Date for the Offering. The option will be exercised by using the accumulated payroll deductions or contributions in the Participant’s account as of each such Purchase Date to purchase the number of full and (to the extent permitted by the Committee) partial shares of Stock that may be purchased at the purchase price on such date, determined in accordance with Section 4.02 (but not in excess of the limitation set forth in Sections 3.03(b) or 3.03(c)). Any accumulated payroll deductions or contributions remaining in the Participant’s account following the purchase that could not be used to purchase shares of Stock in accordance with the foregoing provisions shall be refunded to the Participant as soon as practicable, or retained in the Participant’s account and used for the purchase of Stock in the next Offering, as determined by the Committee.

~~6.02.~~

~~Withdrawal From Offering~~

A Participant may withdraw his or her Subscription at any time (but not retroactively) during an Offering. If the Participant withdraws his or her Subscription with respect to any Offering, the accumulated payroll deductions or contributions in the Participant’s account at the time the Subscription is withdrawn will be used to purchase shares of Stock at the next Purchase Date for the Offering to which the Subscription related, in accordance with Section 6.01, or refunded to the Participant, as determined by the Committee.

~~6.03.~~

~~Delivery of Stock~~

Stock purchased under the Plan will be held in an account in the Participant’s name in uncertificated form until such shares are transferred to the Participant in accordance with Section 7.02 or other procedures established by the Committee. The Committee may change such accounts and the manner in which such shares are registered and held from time to time, and may establish reasonable fees for the registration and custody of shares and sell shares in a Participant’s account to pay such fees.

~~6.04.~~

~~Mandatory Retention or Sale of Stock~~

To facilitate compliance with applicable law, the Committee may require Participants to: (a) retain any Stock purchased under the Plan during an Offering with a designated broker or agent for a designated period of time (and may restrict dispositions during that period) and/or may establish other procedures to restrict transfer of such Stock or (b) sell shares of Stock immediately upon purchase or within a specified period following a Participant’s termination of employment.

~~Dividends~~

Dividends on Stock purchased under the Plan that is held in a Participant’s account shall be credited to the Participant’s account and reinvested in Stock, except to the extent otherwise provided by the Committee.

To the extent permitted under applicable law, the Committee may delegate its power, authority and responsibilities under the Plan to one or more officers of the Company at any time, in its sole discretion. In this regard and to the extent permitted under applicable law, the Committee hereby delegates its power, authority and responsibilities under the Plan to the Company’s senior officer responsible for human resources.

~~10.05.~~

The Committee shall have complete power and authority to terminate or amend the Plan; provided, however, that any amendment that would (i) increase the maximum number of shares which may be issued under any Offering (except pursuant to Section 10.03); or (ii) amend the requirements as to the class of employees eligible to participate in the Plan shall require action by the Board and approval of the shareholders.

~~Unless otherwise determined by the Committee, the termination date of the Plan shall be deemed to be a Purchase Date, and all options then outstanding under the Plan shall be exercised.~~

If the Effective Date does not occur within twelve months after the date on which the Plan is adopted, the Plan shall be null and void.

~~10.09.~~

~~No Employment Rights~~

The Plan does not, directly or indirectly, create any right for the benefit of any employee or class of employees to purchase any shares under the Plan, or create in any employee or class of employees any right with respect to continuation of employment by the Company, and it shall not be deemed to interfere in any way with the Company’s right to terminate, or otherwise modify, an employee’s employment at any time. Any rights or benefits provided under this Plan shall not be considered part of normal or expected compensation for purposes of calculating any severance, resignation, redundancy, end of service payments, bonuses, long service awards, pension, retirement or similar payments, except to the extent explicitly provided in the plan or policy document governing such benefits.
