 Exhibit 10.4 

APPIAN CORPORATION 

INDEMNITY AGREEMENT 

THIS INDEMNITY AGREEMENT (the “Agreement”) is made
and entered into as of                     , between Appian Corporation, a Delaware corporation (the “Company”), and
                     (“Indemnitee”). 

RECITALS 
 A.
Highly competent persons have become more reluctant to serve corporations as directors or officers or in other capacities unless they are provided with adequate protection through insurance or adequate indemnification against inordinate risks of
claims and actions against them arising out of their service to and activities on behalf of the corporation; 
 B. Although furnishing
of insurance to protect persons serving a corporation and its subsidiaries from certain liabilities has been a customary and widespread practice among United States-based corporations and other business enterprises, the Company believes that, given
current market conditions and trends, such insurance may be available to it in the future only at higher premiums and with more exclusions. At the same time, directors, officers, and other persons in service to corporations or business enterprises
are being increasingly subjected to expensive and time-consuming litigation relating to, among other things, matters that traditionally would have been brought only against the Company or business enterprise itself. The Bylaws and Certificate of
Incorporation of the Company require indemnification of the executive officers and directors of the Company and permit indemnification of other officers and certain other persons. Indemnitee may also be entitled to indemnification pursuant to the
General Corporation Law of the State of Delaware (“DGCL”). The Bylaws, Certificate of Incorporation, and the DGCL expressly provide that their respective indemnification provisions are not exclusive, and contemplate that
contracts may be entered into between the Company and members of the Board, officers, and other persons with respect to indemnification; 

C. The uncertainties relating to such liability insurance and to indemnification have increased the difficulty of attracting and
retaining such persons; 
 D. The Board has determined that the increased difficulty in attracting and retaining such persons is
detrimental to the best interests of the Company’s stockholders, and that the Company should act to assure such persons that there will be increased certainty of protection in the future; 

E. It is reasonable, prudent, and necessary for the Company to contractually obligate itself to indemnify, and to advance expenses on
behalf of, such persons to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern that they will not be so indemnified; 

F. This Agreement is a supplement to and in furtherance of the Company’s Bylaws and Certificate of Incorporation and any
resolutions adopted pursuant to such indemnification, and will not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee; 

G. Indemnitee does not regard the protection available under the Company’s Bylaws and Certificate of Incorporation and insurance as
adequate in the present circumstances, and may not be willing to serve as an officer or director without adequate protection, and the Company desires Indemnitee to serve in such capacity. Indemnitee is willing to serve, continue to serve, and to
take on additional service for or on behalf of the Company on the condition that he or she be so indemnified; and 
 H. Indemnitee may
have certain rights to indemnification and insurance provided by other entities or organizations which Indemnitee and such other entities and organizations intend to be secondary to the primary obligation of the Company to indemnify Indemnitee as
provided in this Agreement, with the Company’s acknowledgement and agreement to the foregoing being a material condition to Indemnitee’s willingness to serve on the Board. 

  
 1. 

 I. This Agreement supersedes and replaces in its entirety any previous indemnification
agreement entered into between the Company and the Indemnitee. 
 NOW, THEREFORE, in
consideration of Indemnitee’s agreement to serve as an officer or a director from and after the date first written above, the parties agree as follows: 

1. Indemnity of Indemnitee. The Company agrees to hold harmless and indemnify Indemnitee to the fullest extent permitted by law, as
such may be amended from time to time in accordance with the terms of this Agreement. In furtherance of the this indemnification, and without limiting the generality of such indemnification: 

(a) Proceedings Other Than Proceedings by or in the Right of the Company. Indemnitee will be entitled to the rights of indemnification
provided in this Section 1(a) if, by reason of his or her Corporate Status, the Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding other than a Proceeding by or in the right of the Company. Pursuant to this
Section 1(a), Indemnitee will be indemnified against all Expenses, judgments, penalties, fines, and amounts paid in settlement actually and reasonably incurred by him or her, or on his or her behalf, in connection with such Proceeding or any claim,
issue, or matter. This indemnification is provided if the Indemnitee acted in good faith and in a manner the Indemnitee reasonably believed to be in or not opposed to the best interests of the Company, and with respect to any criminal Proceeding,
had no reasonable cause to believe the Indemnitee’s conduct was unlawful. 
 (b) Proceedings by or in the Right of the Company.
Indemnitee will be entitled to the rights of indemnification provided in this Section 1(b) if, by reason of his or her Corporate Status, the Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding brought by or in the
right of the Company. Pursuant to this Section 1(b), Indemnitee will be indemnified against all Expenses actually and reasonably incurred by the Indemnitee, or on the Indemnitee’s behalf, in connection with such Proceeding if the Indemnitee
acted in good faith and in a manner the Indemnitee reasonably believed to be in, or not opposed to, the best interests of the Company. Indemnification will not be provided against such Expenses if made in respect of any claim, issue, or matter in
such Proceeding as to which Indemnitee will have been adjudged to be liable to the Company unless and to the extent that the Court of Chancery of the State of Delaware will determine that such indemnification may be made. 

(c) Indemnification for Expenses of a Party Who is Wholly or Partly Successful. Notwithstanding any other provision of this Agreement,
to the extent that Indemnitee is, by reason of his or her Corporate Status, a party to and is successful, on the merits or otherwise, in any Proceeding, he or she will be indemnified to the maximum extent permitted by law against all Expenses
actually and reasonably incurred by him or her or on his or her behalf in connection therewith. If Indemnitee is not wholly successful in such Proceeding but is successful, on the merits or otherwise, as to one or more but less than all claims,
issues or matters in such Proceeding, the Company will indemnify Indemnitee against all Expenses actually and reasonably incurred by him or her or on his or her behalf in connection with each successfully resolved claim, issue, or matter. For
purposes of this Section, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, will be deemed to be a successful result as to such claim, issue, or matter. 

2. Additional Indemnity. In addition to, and without regard to any limitations on, the indemnification provided for in Section 1,
the Company agrees to indemnify and hold Indemnitee harmless against all Expenses, judgments, penalties, fines, and amounts paid in settlement actually and reasonably incurred by him or her or on his or her behalf if, by reason of his or her
Corporate Status, he or she is, or is threatened to be made, a party to or participant in any Proceeding (including a Proceeding by or in the right of the Company), including, without limitation, any and all liability arising out of the negligence
or active or passive wrongdoing of Indemnitee. The only limitation that will exist on the Company’s obligations pursuant to this Agreement will be that the Company will not be obligated to make any payment to Indemnitee that is finally
determined (under the procedures, and subject to the presumptions, in Sections 6 and 7) to be unlawful. 

  
 2. 

 3. Contribution. 

(a) Whether or not the indemnification provided in Sections 1 and 2 is available, in respect of any threatened, pending, or completed
action, suit, or proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such action, suit, or proceeding), the Company will pay, in the first instance, the entire amount of any judgment or settlement of such
action, suit, or proceeding without requiring Indemnitee to contribute to such payment, and the Company waives and relinquishes any right of contribution it may have against Indemnitee. The Company will not enter into any settlement of any action,
suit, or proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such action, suit, or proceeding) unless such settlement provides for a full and final release of all claims asserted against Indemnitee. The
Company will not settle any action or claim in a manner that would impose any penalty or admission of guilt or liability on Indemnitee without Indemnitee’s written consent. 

(b) Without diminishing or impairing the obligations of the Company in the preceding subparagraph, if Indemnitee elects or is required
to pay all or any portion of any judgment or settlement in any threatened, pending, or completed action, suit, or proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such action, suit, or proceeding), the
Company will contribute to the amount of Expenses, judgments, fines, and amounts paid in settlement actually and reasonably incurred and paid or payable by Indemnitee in proportion to the relative benefits received by the Company and all officers,
directors, or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action, suit, or proceeding), on the one hand, and Indemnitee, on the other hand, from the transaction from which
such action, suit or proceeding arose. To the extent necessary to conform to law, the proportion determined on the basis of relative benefit may be further adjusted by reference to the relative fault of the Company and all officers, directors, or
employees of the Company other than Indemnitee who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one hand, and Indemnitee, on the other hand, in connection with the events that resulted in such
expenses, judgments, fines, or settlement amounts, as well as any other equitable considerations which the applicable law may require to be considered. The relative fault of the Company and all officers, directors, or employees of the Company, other
than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one hand, and Indemnitee, on the other hand, will be determined by reference to, among other things, the degree to which their
actions were motivated by intent to gain personal profit or advantage, the degree to which their liability is primary or secondary, and the degree to which their respective conduct is active or passive. 

(c) The Company agrees to fully indemnify and hold Indemnitee harmless from any claims of contribution which may be brought by the
Company’s officers, directors, or employees, other than Indemnitee, who may be jointly liable with Indemnitee. 
 (d) To the
fullest extent permissible under applicable law, if the indemnification provided for in this Agreement is unavailable to Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, will contribute to the amount incurred by
Indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid or to be paid in settlement or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair
and reasonable in light of all of the circumstances of such Proceeding to reflect: (i) the relative benefits received by the Company and Indemnitee as a result of the events and transactions giving cause to such Proceeding; and (ii) the
relative fault of the Company (and its directors, officers, employees, and agents) and Indemnitee in connection with such events and transactions. 

  
 3. 

 4. Indemnification for Expenses of a Witness. Notwithstanding any other provision of this
Agreement, to the extent that Indemnitee is, by reason of his or her Corporate Status, a witness, or is made (or asked) to respond to discovery requests, in any Proceeding to which Indemnitee is not a party, he or she will be indemnified against all
Expenses actually and reasonably incurred by him or her or on his or her behalf in connection therewith. 
 5. Advancement of
Expenses. Notwithstanding any other provision of this Agreement, the Company will advance all Expenses incurred by or on behalf of Indemnitee in connection with any Proceeding by reason of Indemnitee’s Corporate Status within 30 days after
the receipt by the Company of a statement from Indemnitee requesting such advance or advances, whether prior to or after final disposition of such Proceeding. Such statement will reasonably evidence the Expenses incurred by Indemnitee and will
include or be preceded or accompanied by a written undertaking by or on behalf of Indemnitee to repay any Expenses advanced if it is ultimately determined that Indemnitee is not entitled to be indemnified against such Expenses. Any advances and
undertakings to repay pursuant to this Section 5 will be unsecured and interest free. 
 6. Procedures and Presumptions for
Determination of Entitlement to Indemnification. It is the intent of this Agreement to secure for Indemnitee rights of indemnity that are as favorable as may be permitted under the DGCL and public policy of the State of Delaware. Accordingly,
the parties agree that the following procedures and presumptions will apply in the event of any question as to whether Indemnitee is entitled to indemnification under this Agreement: 

(a) To obtain indemnification under this Agreement, Indemnitee will submit to the Company a written request with such documentation and
information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification. The Secretary of the Company will, promptly on receipt of such a request for
indemnification, advise the Board in writing that Indemnitee has requested indemnification. Notwithstanding the foregoing, any failure of Indemnitee to provide such request to the Company, or to provide such a request in a timely fashion, will not
relieve the Company of any liability that it may have to Indemnitee unless, and to the extent that, such failure actually and materially prejudices the interests of the Company. 

(b) On written request by Indemnitee for indemnification pursuant to the first sentence of Section 6(a), Indemnitee’s entitlement
to indemnification will be determined in the specific case: 
 (1) by one of the following four methods, which will be at the election of the
Board, unless a Change in Control has occurred: 
 (i) by a majority vote of the Disinterested Directors, even though less than a quorum;

 (ii) by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even though less than a
quorum; 
 (iii) if there are no Disinterested Directors or if the Disinterested Directors so direct, by Independent Counsel in a written
opinion to the Board, a copy of which will be delivered to the Indemnitee; or 
 (iv) if so directed by the Board, by the stockholders of
the Company; or 
 (2) if a Change in Control has occurred, by Independent Counsel in a written opinion to the Board, a copy of which will
be delivered to the Indemnitee 
 Disinterested Directors are those members of the Board who are not parties to the action, suit, or proceeding that
indemnification is sought by Indemnitee. 

  
 4. 

 (c) If the determination of entitlement to indemnification is to be made by Independent
Counsel pursuant to Section 6(b), the Independent Counsel will be selected as provided in this Section 6(c). The Independent Counsel will be selected by the Board and notify the Indemnitee by written notice. Within 10 days after such notice has been
given, Indemnitee may deliver the Company a written objection to such selection. But, that objection may only be asserted on the ground that the Independent Counsel does not meet the requirements of “Independent Counsel” as
defined in Section 13, and the objection will include with particularity the factual basis of such assertion. Absent a proper and timely objection, the person so selected will act as Independent Counsel. If a written objection is made and
substantiated, the Independent Counsel selected may not serve as Independent Counsel unless and until such objection is withdrawn or a court has determined that such objection is without merit. If no Independent Counsel will have been selected and
not objected to within 20 days after submission by Indemnitee of a written request for indemnification pursuant to Section 6(a), either the Company or Indemnitee may petition the Court of Chancery of the State of Delaware or other court of competent
jurisdiction for resolution of any objection made by the Indemnitee to the Company’s selection of Independent Counsel or for the appointment of a person selected by the court or by such other person as the court designates to serve as
Independent Counsel. The person with respect to whom all objections are so resolved or the person so appointed will act as Independent Counsel under Section 6(b). The Company will pay any and all reasonable fees and expenses of Independent Counsel
incurred by such Independent Counsel in connection with acting pursuant to Section 6(b), and the Company will pay all reasonable fees and expenses incident to the procedures of this Section 6(c), regardless of the manner in which such Independent
Counsel was selected or appointed. In no event will Indemnitee be liable for fees and expenses incurred by such Independent Counsel. 

(d) In making a determination with respect to entitlement to indemnification under this Agreement, the person or persons or entity
making such determination will presume that Indemnitee is entitled to indemnification under this Agreement. Anyone seeking to overcome this presumption will have the burden of proof and the burden of persuasion by clear and convincing evidence.
Neither the failure of the Company (including by its Board or Independent Counsel) to have made a determination prior to the commencement of any action pursuant to this Agreement that indemnification is proper in the circumstances because Indemnitee
has met the applicable standard of conduct, nor an actual determination by the Company (including by its Board or Independent Counsel) that Indemnitee has not met such applicable standard of conduct, will be a defense to the action or create a
presumption that Indemnitee has not met the applicable standard of conduct. 
 (e) Indemnitee will be deemed to have acted in good
faith if Indemnitee’s action is based on the records or books of account of the Enterprise, including financial statements, or on information supplied to Indemnitee by the officers of the Enterprise in the course of their duties, or on the
advice of legal counsel for the Enterprise or on information or records given or reports made to the Enterprise by an independent certified public accountant or by an appraiser or other expert selected with reasonable care by the Enterprise. In
addition, the knowledge and actions, or failure to act, of any director, officer, agent, or employee of the Enterprise will not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement. Whether or not
the foregoing provisions of this Section 6(e) are satisfied, it will in any event be presumed that Indemnitee has at all times acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the
Company. Anyone seeking to overcome this presumption will have the burden of proof and the burden of persuasion by clear and convincing evidence. 

(f) If the person, persons, or entity empowered or selected under Section 6 to determine whether Indemnitee is entitled to
indemnification has not have made a determination within 60 days after receipt by the Company of the request, the requisite determination of entitlement to indemnification will be deemed to have been made, and Indemnitee will be entitled to such
indemnification absent (i) a misstatement by Indemnitee of a material fact or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading in connection with the request for indemnification, or
(ii) a prohibition of such indemnification under applicable law. Such 60-day period may be extended for a reasonable time, not to exceed an additional 30 days, if the person, persons, or entity making
such determination with respect to entitlement to indemnification in good faith requires such 

  
 5. 

 
additional time to obtain or evaluate documentation or information relating thereto. The provisions of this Section 6(f) will not apply if the determination of entitlement to indemnification is
to be made by the stockholders pursuant to Section 6(b) and if (A) within 15 days after receipt by the Company of the request for such determination, the Board or the Disinterested Directors, if appropriate, resolve to submit such determination
to the stockholders for their consideration at an annual meeting to be held within 75 days after such receipt, and such determination is made at that annual meeting, or (B) a special meeting of stockholders is called within 15 days after such
receipt for the purpose of making such determination, such meeting is held for such purpose within 60 days after having been so called and such determination is made at that annual meeting. 

(g) Indemnitee will cooperate with the person, persons. or entity making such determination with respect to Indemnitee’s
entitlement to indemnification, including providing such person, persons, or entity on reasonable advance request any documentation or information which is not privileged or otherwise protected from disclosure and which is reasonably available to
Indemnitee and reasonably necessary to such determination. Any Independent Counsel, member of the Board, or stockholder of the Company will act reasonably and in good faith in making a determination regarding the Indemnitee’s entitlement to
indemnification under this Agreement. Any costs or expenses (including attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the person, persons, or entity making such determination will be borne by the Company
(irrespective of the determination as to Indemnitee’s entitlement to indemnification), and the Company indemnifies and agrees to hold Indemnitee harmless therefrom. 

(h) The Company acknowledges that a settlement or other disposition short of final judgment may be successful if it permits a party to
avoid expense, delay, distraction, disruption, and uncertainty. In the event that any action, claim, or proceeding to which Indemnitee is a party is resolved in any manner other than by adverse judgment against Indemnitee (including, without
limitation, settlement of such action, claim or proceeding with or without payment of money or other consideration) it will be presumed that Indemnitee has been successful on the merits or otherwise in such action, suit, or proceeding. Anyone
seeking to overcome this presumption will have the burden of proof and the burden of persuasion by clear and convincing evidence. 
 (i)
The termination of any Proceeding or of any claim, issue, or matter in any Proceeding, by judgment, order, settlement or conviction, or on a plea of nolo contendere or its equivalent, will not (except as otherwise expressly provided in this
Agreement) of itself adversely affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of
the Company or, with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that his or her conduct was unlawful. 

7. Remedies of Indemnitee. 

(a) In the event that (i) a determination is made pursuant to Section 6 that Indemnitee is not entitled to indemnification
under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 5, (iii) no determination of entitlement to indemnification is made pursuant to Section 6(b) within 90 days after receipt by the Company of the
request for indemnification, (iv) payment of indemnification is not made pursuant to this Agreement within 10 days after receipt by the Company of a written request for such payment, or (v) payment of indemnification is not made within 10
days after a determination has been made that Indemnitee is entitled to indemnification or such determination is deemed to have been made pursuant to Section 6, Indemnitee will be entitled to an adjudication in an appropriate court of the State
of Delaware, or in any other court of competent jurisdiction, of Indemnitee’s entitlement to such indemnification. Indemnitee will commence such proceeding seeking an adjudication within 1 year following the date on which Indemnitee first has
the right to commence such proceeding pursuant to this Section 7(a). The Company will not oppose Indemnitee’s right to seek any such adjudication. 

  
 6. 

 (b) In the event that a determination has been made pursuant to Section 6(b) that
Indemnitee is not entitled to indemnification, any judicial proceeding commenced pursuant to this Section 7 will be conducted in all respects as a de novo trial on the merits, and Indemnitee will not be prejudiced by reason of the adverse
determination under Section 6(b). 
 (c) If a determination has been made pursuant to Section 6(b) that Indemnitee is entitled to
indemnification, the Company will be bound by such determination in any judicial proceeding commenced pursuant to this Section 7, absent (i) a misstatement by Indemnitee of a material fact or an omission of a material fact necessary to
make Indemnitee’s misstatement not materially misleading in connection with the application for indemnification, or (ii) a prohibition of such indemnification under applicable law. 

(d) In the event that Indemnitee, pursuant to this Section 7, seeks a judicial adjudication of his or her rights under, or to
recover damages for breach of, this Agreement, or to recover under any directors’ and officers’ liability insurance policies maintained by the Company, the Company will pay on his or her behalf, in advance, any and all expenses (of the
types described in the definition of Expenses) actually and reasonably incurred by him or her in such judicial adjudication, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement of expenses,
or insurance recovery. 
 (e) The Company will be precluded from asserting in any judicial proceeding commenced pursuant to this
Section 7 that the procedures and presumptions of this Agreement are not valid, binding, and enforceable, and will stipulate in any such court that the Company is bound by all the provisions of this Agreement. The Company will indemnify
Indemnitee against any and all Expenses and, if requested by Indemnitee, will (within 10 days after receipt by the Company of a written request therefore) advance, to the extent not prohibited by law, such expenses to Indemnitee, which are incurred
by Indemnitee in connection with any action brought by Indemnitee for indemnification or advance of Expenses from the Company under this Agreement or under any directors’ and officers’ liability insurance policies maintained by the
Company, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement of Expenses, or insurance recovery, as the case may be. 

(f) Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement to indemnification under this
Agreement will be required to be made prior to the final disposition of the Proceeding. 
 8.
Non-Exclusivity; Survival of Rights; Insurance; Primacy of Indemnification; Subrogation. 

(a) The rights of indemnification as provided by this Agreement will not be deemed exclusive of any other rights to which Indemnitee may
at any time be entitled under applicable law, the Certificate of Incorporation, the Bylaws, any agreement, a vote of stockholders, a resolution of Board, or otherwise. No amendment, alteration, or repeal of this Agreement or of any provision of this
Agreement will limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee in his or her Corporate Status prior to such amendment, alteration, or repeal. To the extent that a change in
the DGCL, whether by statute or judicial decision, permits greater indemnification than would be afforded currently under the Certificate of Incorporation, Bylaws, and this Agreement, it is the intent of the parties of this Agreement that Indemnitee
will enjoy all greater benefits so afforded by such change. No right or remedy in this Agreement conferred is intended to be exclusive of any other right or remedy, and every other right and remedy will be cumulative and in addition to every other
right and remedy given under this Agreement or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy under this Agreement, or otherwise, will not prevent the concurrent assertion or employment
of any other right or remedy. 
 (b) To the extent that the Company maintains an insurance policy or policies providing liability
insurance for directors, officers, employees, or agents, or fiduciaries of the Company or of any other corporation, partnership, joint venture, trust, employee benefit plan, or other enterprise that 

  
 7. 

 
such person serves at the request of the Company, the Company will procure such insurance policy or policies under which the Indemnitee will be covered in accordance with its or their terms to
the maximum extent of the coverage available for any director, officer, employee, agent, or fiduciary under such policy or policies. If, at the time of the receipt of a notice of a claim pursuant to the terms of this Agreement, the Company has
director and officer liability insurance in effect, the Company will give prompt notice of the commencement of such proceeding to the insurers in accordance with the procedures in the respective policies. The Company will thereafter take all
necessary or desirable action to cause such insurers to pay, on behalf of the Indemnitee, all amounts payable as a result of such proceeding in accordance with the terms of such policies. 

(c) The Company acknowledges that Indemnitee has or may have in the future certain rights to indemnification, advancement of expenses,
or insurance provided by other entities or organizations (collectively, the “Secondary Indemnitors”). The Company agrees that (i) it is the indemnitor of first resort (i.e., its obligations to Indemnitee are primary and
any obligation of the Secondary Indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities incurred by Indemnitee are secondary), (ii) it will be required to advance the full amount of expenses incurred by
Indemnitee and will be liable for the full amount of all Expenses, judgments, penalties, fines, and amounts paid in settlement to the extent legally permitted and as required by the terms of this Agreement, the Company’s Certificate of
Incorporation or Bylaws (or any other agreement between the Company and Indemnitee), without regard to any rights Indemnitee may have against the Secondary Indemnitors, and (iii) it irrevocably waives, relinquishes, and releases the Secondary
Indemnitors from any and all claims against the Secondary Indemnitors for contribution, subrogation, or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the Secondary Indemnitors on
behalf of Indemnitee with respect to any claim for which Indemnitee has sought indemnification from the Company will affect the foregoing and the Secondary Indemnitors will have a right of contribution and be subrogated to the extent of such
advancement or payment to all of the rights of recovery of Indemnitee against the Company. The Company and Indemnitee agree that the Secondary Indemnitors are express third party beneficiaries of the terms of this Section 8(c). 

(d) Except as provided in Section 8(c), in the event of any payment under this Agreement, the Company will be subrogated to the extent
of such payment to all of the rights of recovery of Indemnitee (other than against the Secondary Indemnitors), who will execute all papers required and take all action necessary to secure such rights, including execution of such documents as are
necessary to enable the Company to bring suit to enforce such rights. 
 (e) Except as provided in Section 8(c), the Company will not
be liable under this Agreement to make any payment of amounts otherwise indemnifiable under this Agreement if and to the extent that Indemnitee has otherwise actually received such payment under any insurance policy, contract, agreement, or
otherwise. 
 (f) Except as provided in Section 8(c), the Company’s obligation to indemnify or advance Expenses under this
Agreement to Indemnitee who is or was serving at the request of the Company as a director, officer, employee, or agent of any other corporation, partnership, joint venture, trust, employee benefit plan, or other enterprise will be reduced by any
amount Indemnitee has actually received as indemnification or advancement of expenses from such other corporation, partnership, joint venture, trust, employee benefit plan, or other enterprise. 

9. Exceptions to Right of Indemnification. Notwithstanding any provision in this Agreement, the Company will not be obligated under
this Agreement to make any indemnity in connection with any claim made against Indemnitee: 
 (a) for which payment has actually been
made to or on behalf of Indemnitee under any insurance policy or other indemnity provision, except with respect to any excess beyond the amount paid under any insurance policy or other indemnity provision, provided, that the foregoing will not
affect the rights of Indemnitee or the Secondary Indemnitors in Section 8(c); 

  
 8. 

 (b) for an accounting of profits made from the purchase and sale (or sale and purchase) by
Indemnitee of securities of the Company within the meaning of Section 16(b) of the Exchange Act, or similar provisions of state statutory law or common law; 

(c) in connection with any Proceeding (or any part of any Proceeding) initiated by Indemnitee, including any Proceeding (or any part of
any Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees, or other indemnitees, unless (i) the Board authorized the Proceeding (or any part of any Proceeding) prior to its initiation, or (ii) the
Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law; 
 (d)
with respect to remuneration paid to Indemnitee if it is determined by final judgment or other final adjudication that such remuneration was in violation of law (and, in this respect, both the Company and Indemnitee have been advised that
the Securities and Exchange Commission believes that indemnification for liabilities arising under the federal securities laws is against public policy and is, therefore, unenforceable and that claims for indemnification should be submitted to
appropriate courts for adjudication, as indicated in the last paragraph of this Section 9); 
 (e) a final judgment or other
final adjudication is made that Indemnitee’s conduct was in bad faith, knowingly fraudulent or deliberately dishonest or constituted willful misconduct (but only to the extent of such specific determination); 

(f) in connection with any claim for reimbursement of the Company by Indemnitee of any bonus or other incentive-based or equity-based
compensation or of any profits realized by Indemnitee from the sale of securities of the Company, as required in each case under the Exchange Act (including any such reimbursements that arise from an accounting restatement of the Company pursuant to
Section 304 of the Sarbanes-Oxley Act, or the payment to the Company of profits arising from the purchase and sale by Indemnitee of securities in violation of Section 306 of the Sarbanes-Oxley Act), if Indemnitee is held liable therefor
(including pursuant to any settlement); or 
 (g) on account of conduct that is established by a final judgment as constituting a
breach of Indemnitee’s duty of loyalty to the Company or resulting in any personal profit or advantage to which Indemnitee is not legally entitled. 

For purposes of this Section 9, a final judgment or other adjudication may be reached in either the underlying proceeding or action in
connection with which indemnification is sought or a separate proceeding or action to establish rights and liabilities under this Agreement. 

Any provision herein to the contrary notwithstanding, the Company will not be obligated pursuant to the terms of this Agreement to indemnify
Indemnitee or otherwise act in violation of any undertaking appearing in and required by the rules and regulations promulgated under the Securities Act, or in any registration statement filed with the SEC under the Securities Act. Indemnitee
acknowledges that paragraph (h) of Item 512 of Regulation S-K promulgated under the Securities Act currently generally requires the Company to undertake, in connection with any registration statement
filed under the Securities Act, to submit the issue of the enforceability of Indemnitee’s rights under this Agreement in connection with any liability under the Securities Act on public policy grounds to a court of appropriate jurisdiction and
to be governed by any final adjudication of such issue. Indemnitee specifically agrees that any such undertaking will supersede the provisions of this Agreement and to be bound by any such undertaking. 

10. Duration of Agreement. All agreements and obligations of the Company contained herein will continue during the period Indemnitee is
an officer or director of the Company (or is or was serving at the request of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise) and will continue thereafter so long
as Indemnitee will be subject to any Proceeding (or any proceeding commenced under Section 7) by reason of his or her Corporate Status, whether or not he or she is acting or serving in any such capacity at the time any

  
 9. 

 
liability or expense is incurred for which indemnification can be provided under this Agreement. This Agreement will be binding on and inure to the benefit of and be enforceable by the parties of
this Agreement and their respective successors (including any direct or indirect successor by purchase, merger, consolidation, or otherwise to all or substantially all of the business or assets of the Company), assigns, spouses, heirs, executors,
and personal and legal representatives. 
 11. Security. To the extent requested by Indemnitee and approved by the Board, the Company
may at any time and from time to time provide security to Indemnitee for the Company’s obligations under this Agreement through an irrevocable bank line of credit, funded trust, or other collateral. Any such security, once provided to
Indemnitee, may not be revoked or released without the prior written consent of the Indemnitee. 
 12. Enforcement. 

(a) The Company expressly confirms and agrees that it has entered into this Agreement and assumes the obligations imposed on it to
induce Indemnitee to serve as an officer or director of the Company, and the Company acknowledges that Indemnitee is relying on this Agreement in serving as an officer or director of the Company.

her or of any inaction on his or her part while acting as an officer or director of the Company, or by reason of the fact that he or she is or was serving at the request of the Company as a director, officer, employee, agent or fiduciary of another
corporation, partnership, joint venture, trust or other Enterprise; in each case whether or not he or she is acting or serving in any such capacity at the time any liability or expense is incurred for which indemnification can be provided under this

any other provision. Without limiting the generality of the foregoing, this Agreement is intended to confer upon Indemnitee indemnification rights to the fullest extent permitted by applicable laws. In the event any provision hereof conflicts with
any applicable law, such provision will be deemed modified, consistent with the aforementioned intent, to the extent necessary to resolve such conflict. 

15. Modification and Waiver. No supplement, modification, termination or amendment of this Agreement will be binding unless executed in
writing by both of the parties hereto. No waiver of any of the provisions of this Agreement will be deemed or will constitute a waiver of any other provisions hereof (whether or not similar) nor will such waiver constitute a continuing waiver. 

16. Notice By Indemnitee. Indemnitee agrees promptly to notify the Company in writing upon being served with or otherwise receiving any
summons, citation, subpoena, complaint, indictment, information or other document relating to any Proceeding or matter which may be subject to indemnification covered under this Agreement. The failure to so notify the Company will not relieve the
Company of any obligation which it may have to Indemnitee under this Agreement or otherwise unless and only to the extent that such failure or delay materially prejudices the Company. 

17. Notices. All notices and other communications given or made pursuant to this Agreement will be in writing and will be deemed
effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed electronic mail or facsimile if sent during normal business hours of the recipient, and if not so confirmed, then on the next business

			FIFTH AMENDMENT TO REPUBLIC BANK BUILDING LEASE
		

		
			9600 BROWNSBORO ROAD,  JEFFERSON COUNTY, KENTUCKY
		

		
			This Fifth Amendment to Lease dated as of March 15, 2017,  with an effective date as of the Commencement date as hereinafter defined, is made to the Republic Bank Building Lease dated August 1, 1999, as amended, between Jaytee Properties, a Kentucky general partnership, now known as Jaytee-Springhurst, LLC, hereinafter referred to as "Landlord" and Republic Bank & Trust Company, hereinafter referred to as the "Tenant".  As parties hereto, Landlord and Tenant hereby agree to further modify and amend their original Lease Agreement, as amended, as hereafter set forth.
		

		
			Landlord and Tenant agree that the Lease, shall be amended to increase the rentable square footage under lease by adding, effective as of the date the additional space becoming available for occupancy by the Tenant (the “Commencement Date”), an additional 5,170 rentable square feet on the first floor,  and an additional 5,722 rentable square feet on the second floor, and an additional 8,292 square feet on the third floor, with all the aforementioned additional space at $18.50 per rentable square foot, all additional space located in the Republic Bank Building. 
		

		
			The Tenant’s rent for the additional space referenced herein, totaling 19,184 rentable square feet, shall be Twenty Nine Thousand, Five Hundred Seventy Five Dollars and  33/100 ($29,575.33) per month.  
		

		
			If the Commencement date occurs within any calendar month, the rent shall be pro-rated accordingly for the first calendar month.  Any improvements or alterations to the additional leased space shall be at the expense of Tenant and subject to the prior approval of Landlord. Landlord permits Tenant to enter into possession of the Premises prior to the Lease Commencement Date in order to complete Tenant improvements without the payment of Rent. 
		

		
			The initial term for the additional leased space shall run from the Commencement Date to July 31, 2024, with Tenant having one five- year option to renew the additional space at the same rental rate stated herein plus an adjustment for a CPI increase.  Rent shall be increased during the option period, if exercised, by the most recent five-year average CPI increase to be calculated as of the last five (5) years of the term of the additional leased space and continue in accordance with the terms of that original lease, as amended, referenced herein, except as otherwise provided under this Fifth Amendment.
