Item 6. Indemnification of Directors and Officers

Articles 10 and 11 of the Articles of Incorporation of FSB Bancorp, Inc. (the "Corporation" for purposes of this Item 6) set forth circumstances under which directors, officers, employees and agents of the Corporation may be insured or indemnified against liability which they incur in their capacities as such:

ARTICLE 10. Indemnification, etc. of Directors and Officers.

A. Indemnification. The Corporation shall indemnify (1) its current and former directors and officers, whether serving the Corporation or at its request any other entity, to the fullest extent required or permitted by the Maryland General Corporation Law ("MGCL") now or hereafter in force, including the advancement of expenses under the procedures and to the fullest extent permitted by law, and (2) other employees and agents to such extent as shall be authorized by the Board of Directors and permitted by law; provided, however, that, except as provided in Section B of this Article 10 with respect to proceedings to enforce rights to indemnification, the Corporation shall indemnify any such indemnitee in connection with a proceeding (or part thereof) initiated by such indemnitee only if such proceeding (or part thereof) was authorized by the Board of Directors of the Corporation.

B. Procedure. If a claim under Section A of this Article 10 is not paid in full by the Corporation within sixty (60) days after a written claim has been received by the Corporation, except in the case of a claim for an advancement of expenses, in which case the applicable period shall be twenty (20) days, the indemnitee may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim. If successful in whole or in part in any such suit, or in a suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the indemnitee shall also be entitled to be reimbursed the expense of prosecuting or defending such suit. It shall be a defense to any action for advancement of expenses that the Corporation has not received both (i) an undertaking as required by law to repay such advances in the event it shall ultimately be determined that the standard of conduct has not been met and (ii) a written affirmation by the indemnitee of his good faith belief that the standard of conduct necessary for indemnification by the Corporation has been met. In (i) any suit brought by the indemnitee to enforce a right to indemnification hereunder (but not in a suit brought by the indemnitee to enforce a right to an advancement of expenses) it shall be a defense that, and (ii) any suit by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking the Corporation shall be entitled to recover such expenses upon a final adjudication that, the indemnitee has not met the applicable standard for indemnification set forth in the MGCL. Neither the failure of the Corporation (including its Board of Directors, independent legal counsel, or its stockholders) to have made a determination prior to the commencement of such suit that indemnification of the indemnitee is proper in the circumstances because the indemnitee has met the applicable standard of conduct set forth in the MGCL, nor an actual determination by the Corporation (including its Board of Directors, independent legal counsel, or its stockholders) that the indemnitee has not met such applicable standard of conduct, shall create a presumption that the indemnitee has not met the applicable standard of conduct or, in the case of such a suit brought by the indemnitee, be a defense to such suit. In any suit brought by the indemnitee to enforce a right to indemnification or to an advancement of expenses hereunder, or by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the burden of proving that the indemnitee is not entitled to be indemnified, or to such advancement of expenses, under this Article 10 or otherwise shall be on the Corporation.

C. Non-Exclusivity. The rights to indemnification and to the advancement of expenses conferred in this Article 10 shall not be exclusive of any other right that any Person may have or hereafter acquire under any statute, these Articles, the Corporation's Bylaws, any agreement, any vote of stockholders or the Board of Directors, or otherwise.

D. Insurance. The Corporation may maintain insurance, at its expense, to insure itself and any director, officer, employee or agent of the Corporation or another corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss, whether or not the Corporation would have the power to indemnify such Person against such expense, liability or loss under the MGCL.

E. Miscellaneous. The Corporation shall not be liable for any payment under this Article 10 in connection with a claim made by any indemnitee to the extent such indemnitee has otherwise actually received payment under any insurance policy, agreement, or otherwise, of the amounts otherwise indemnifiable hereunder. The rights to indemnification and to the advancement of expenses conferred in Sections A and B of this Article 10 shall be contract rights and such rights shall continue as to an indemnitee who has ceased to be a director or officer and shall inure to the benefit of the indemnitee's heirs, executors and administrators.

F. Limitations Imposed by Federal Law. Notwithstanding any other provision set forth in this Article 10, in no event shall any payments made by the Corporation pursuant to this Article 10 exceed the amount permissible under applicable federal law, including, without limitation, Section 18(k) of the Federal Deposit Insurance Act and the regulations promulgated thereunder.

Any repeal or modification of this Article 10 shall not in any way diminish any rights to indemnification or advancement of expenses of such director or officer or the obligations of the Corporation arising hereunder with respect to events occurring, or claims made, while this Article 10 is in force.

ARTICLE 11. Limitation of Liability. An officer or director of the Corporation, as such, shall not be liable to the Corporation or its stockholders for money damages, except (A) to the extent that it is proved that the Person actually received an improper benefit or profit in money, property or services, for the amount of the benefit or profit in money, property or services actually received; or (B) to the extent that a judgment or other final adjudication adverse to the Person is entered in a proceeding based on a finding in the proceeding that the Person's action, or failure to act, was the result of active and deliberate dishonesty and was material to the cause of action adjudicated in the proceeding; or (C) to the extent otherwise provided by the MGCL. If the MGCL is amended to further eliminate or limit the personal liability of officers and directors, then the liability of officers and directors of the Corporation shall be eliminated or limited to the fullest extent permitted by the MGCL, as so amended.

Any repeal or modification of the foregoing paragraph by the stockholders of the Corporation shall not adversely affect any right or protection of a director or officer of the Corporation existing at the time of such repeal or modification.

Item 9. Undertakings

The undersigned registrant hereby undertakes:

1. To file, during any period in which offers or sales are being made, a post-effective amendment to the Registration Statement to include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;

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

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

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

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

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

SIGNATURES

The Registrant. Pursuant to the requirements of the Securities Act, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Registration Statement on Form S-8 to be signed on its behalf by the undersigned, thereunto duly authorized, in the Village of Fairport, in the State of New York, on this 27 ^th day of September, 2017.
