 Exhibit 10.6 
 FORM OF 
 INDEMNIFICATION AGREEMENT 

THIS INDEMNIFICATION AGREEMENT (this “Agreement”) is made and entered into as of
            , 20    , by and between Entellus Medical, Inc. (the “Company”) and
[            ] (“Indemnitee”). 
 RECITALS 
 WHEREAS, the Company values Indemnitee’s service to
the Company as a director or officer and desires that Indemnitee continue to serve the Company in such capacity; 

WHEREAS, Indemnitee does not regard the protection available under the organizational documents of the Company and any insurance
policies maintained by the Company as adequate in the present circumstances, and Indemnitee may not be willing to continue to serve in his or her capacity as a director or officer of the Company without the additional protections set forth in this
Agreement; 
 WHEREAS, the Board of Directors of the Company (the “Board”)
has determined that, on the basis of the foregoing, it is reasonable, prudent and necessary for the Company to obligate itself contractually to indemnify, and to advance expenses on behalf of, Indemnitee to the fullest extent permitted by applicable
law so that Indemnitee will serve or continue to serve the Company free from undue concern that he or she will not be so indemnified; 
 WHEREAS, this Agreement is a supplement to and in furtherance of the organizational documents of the Company and any resolutions adopted pursuant thereto, and shall not be deemed a substitute
therefor, nor to diminish or abrogate any rights of Indemnitee thereunder; and 
 WHEREAS, Indemnitee may have
certain rights to indemnification and/or insurance provided by an investment or venture capital fund with which Indemnitee is or may become affiliated (the “Associated Fund”) which Indemnitee and the Associated
Fund intend to be secondary to the primary obligation of the Company to indemnify Indemnitee as provided herein, with the Company’s acknowledgement and agreement to the foregoing being a material condition to Indemnitee’s willingness to
serve on the Board. 
 NOW, THEREFORE, in consideration of the mutual promises and agreements herein contained, and
intending to be legally bound, the parties hereto agree as follows: 
 AGREEMENT 

1. INDEMNIFICATION OF INDEMNITEE AND ASSOCIATED
FUND. The Company hereby agrees to hold harmless and indemnify Indemnitee to the fullest extent permitted by applicable law, as such may be amended from time to time. In furtherance of the foregoing indemnification,
and without limiting the generality thereof: 







 (a) Indemnitee shall be entitled to the rights of indemnification provided in this
Section 1(a) if, by reason of his or her Corporate Status (as defined in Section 13(c)), the Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding (as defined in Section 13(j))
other than a Proceeding by or in the right of the Company. Pursuant to this Section 1(a), Indemnitee shall be indemnified against all Expenses (as defined in Section 13(g)), 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 therein, 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) Indemnitee shall 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 shall 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; provided, however, that if applicable law so provides, no indemnification against such Expenses shall be made in respect of any claim, issue or matter in such Proceeding as to which Indemnitee shall
have been adjudged to be liable to the Company unless and to the extent that a court of competent jurisdiction shall determine that such indemnification may be made. 
 (c) 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 shall be indemnified to the maximum extent permitted by law, as such may be amended from time to time, 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 shall 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 1(c) and without limitation, the termination of any claim, issue
or matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter. 
 (d) If the Associated Fund is, or is threatened to be made, a party to or a participant in any Proceeding relating to or arising by reason of the Associated Fund’s position as a stockholder
of, or lender to, the Company, or the Associated Fund’s appointment of or affiliation with Indemnitee or any other director, including without limitation any alleged misappropriation of a Company asset or corporate opportunity, any claim of
misappropriation or infringement of intellectual property relating to the Company, any alleged false or misleading statement or omission made by the Company (or on its behalf) or its employees or agents, or any allegation of inappropriate control or
influence over the Company or its Board members, officers, equity holders or debt holders, then the Associated Fund will be entitled to indemnification hereunder for Expenses to the same extent as Indemnitee, and the terms of this Agreement as they
relate to procedures for indemnification of Indemnitee and advancement of Expenses shall apply to any  

  
 2 








 
such indemnification of the Associated Fund. The rights provided to the Associated Fund under this Section 1(d) shall: (i) be suspended during any period during which the
Associated Fund does not have a representative on the Board; and (ii) terminate on an initial public offering of the Company’s Common Stock under the Securities Act of 1933, as amended (an “IPO”); provided,
however, that in the event of any such suspension or termination, the Associated Fund’s rights to indemnification will not be suspended or terminated with respect to any Proceeding based in whole or in part on facts and circumstances
occurring at any time prior to such suspension or termination regardless of whether the Proceeding arises before or after such suspension or termination. The Company and Indemnitee agree that the Associated Fund is an express third party beneficiary
of the terms of this Section 1(d). 
 2. ADDITIONAL INDEMNITY. In addition to,
and without regard to any limitations on, the indemnification provided for in Section 1 of this Agreement, the Company shall and hereby does indemnify and hold harmless Indemnitee 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, all liability arising out of the negligence or active or passive wrongdoing of Indemnitee. The only limitation that shall exist upon the Company’s obligations
pursuant to this Agreement shall be that the Company shall not be obligated to make any payment to Indemnitee that is finally determined (under the procedures, and subject to the presumptions, set forth in Sections 6 and 7 hereof)
to be unlawful. 
 3. CONTRIBUTION. 

(a) Whether or not the indemnification provided in Sections 1 and 2 hereof is available, in respect of any
Proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such Proceeding), the Company shall pay, in the first instance, the entire amount of any judgment or settlement of such Proceeding without requiring
Indemnitee to contribute to such payment and the Company hereby waives and relinquishes any right of contribution it may have against Indemnitee. The Company shall not enter into any settlement of any Proceeding in which the Company is jointly
liable with Indemnitee (or would be if joined in such Proceeding) unless such settlement provides for a full and final release of all claims asserted against Indemnitee. 
 (b) Without diminishing or impairing the obligations of the Company set forth in Section 3(a), if, for any reason, Indemnitee shall elect or be required to pay all or any portion of any
judgment or settlement in any Proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such Proceeding), the Company shall 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 Proceeding), on the one hand, and Indemnitee, on the other hand, from the transaction from which such Proceeding arose; provided, however, that the proportion determined on the basis of relative benefit
may, to the extent necessary to conform to law, 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


  
 3 








 
jointly liable with Indemnitee (or would be if joined in such 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 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 Proceeding), on the one hand, and Indemnitee, on the other hand, shall 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 conduct is active or passive. 
 (c) The Company hereby agrees to fully indemnify and hold Indemnitee harmless from any claims of contribution which may be brought by officers, directors or employees of the Company, 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, shall contribute to the amount incurred by Indemnitee, whether for judgments, fines,
penalties, excise taxes, amounts paid or to be paid in settlement and/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 in order to reflect: (i) the relative benefits received by the Company and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Proceeding; and/or (ii) the relative fault of the
Company (and its directors, officers, employees and agents) and Indemnitee in connection with such event(s) and/or transaction(s). 

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 shall 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 shall advance all Expenses incurred by or on behalf of Indemnitee in connection with any Proceeding by reason of Indemnitee’s Corporate Status within thirty (30) days after the receipt by the Company of a statement or statements
from Indemnitee requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by Indemnitee and shall include or be
preceded or accompanied by a written undertaking by or on behalf of Indemnitee to repay any Expenses advanced if it shall ultimately be determined that Indemnitee is not entitled to be indemnified against such Expenses. Any advances and undertakings
to repay pursuant to this Section 5 shall be unsecured and interest free. 
 6. PROCEDURES
AND PRESUMPTIONS FOR DETERMINING ENTITLEMENT TO INDEMNIFICATION. It is the intent of this Agreement to secure for Indemnitee
rights of indemnification that are as favorable as may be permitted under applicable law. Accordingly, the parties agree that the following procedures and presumptions shall apply in the event of any question as to whether Indemnitee is entitled to
indemnification under this Agreement: 

  
 4 








 (a) To obtain indemnification under this Agreement, Indemnitee shall submit to the
Company a written request, including therein or therewith 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 shall, promptly upon 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 a
request to the Company, or to provide such a request in a timely fashion, shall 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) Upon written request by Indemnitee for indemnification pursuant to the first sentence of
Section 6(a) hereof, a determination with respect to Indemnitee’s entitlement thereto shall be made in the specific case by one of the following four methods, which shall be at the election of the Board: (i) by a majority vote
of the Disinterested Directors (as defined in Section 13(d)), even though less than a quorum; (ii) by a committee of those 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 (as defined in Section 13(h)) in a written opinion to the Board, a copy of which shall be delivered to the
Indemnitee, or (iv) if so directed by the Board, by the stockholders of the Company; provided, however, that, notwithstanding the foregoing, any determination with respect to Indemnitee’s entitlement to indemnification
hereunder that is made at any time following the consummation of a Change in Control (as defined in Section 13(b)) that occurs at any time when the Company has a class of securities registered under the Exchange Act (as defined in
Section 13(f)) or following the consummation of an IPO shall be made solely by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to the Indemnitee. 

(c) If the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 6(b)
hereof, the Independent Counsel shall be selected as provided in this Section 6(c). The Independent Counsel shall be selected by the Board. Indemnitee may, within 10 days after such written notice of selection shall have been given,
deliver to the Company a written objection to such selection; provided, however, that such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of “Independent
Counsel” as defined in Section 13(h) of this Agreement, and the objection shall set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the person so selected shall 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, within
20 days after submission by Indemnitee of a written request for indemnification pursuant to Section 6(a) hereof, no Independent Counsel shall have been selected and not objected to, either the Company or Indemnitee may petition a court of
competent jurisdiction for resolution of any objection which shall have been made by the Indemnitee to the Company’s selection of Independent Counsel and/or for the appointment as Independent Counsel of a person selected by the court or by such
other person as the court shall designate, and the person with respect to whom all objections are so resolved or the person so appointed shall act as Independent Counsel under Section 6(b) hereof. The Company shall pay any and all reasonable
fees and expenses of Independent Counsel incurred by such Independent 

  
 5 








 
Counsel in connection with acting pursuant to Section 6(b) hereof, and the Company shall 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. 
 (d) In making a determination with respect
to entitlement to indemnification hereunder, the person or persons or entity making such determination shall presume that Indemnitee is entitled to indemnification under this Agreement. Anyone seeking to overcome this presumption shall have the
burden of proof and the burden of persuasion by clear and convincing evidence. Neither the failure of the Company (including by its directors or independent legal 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 directors or independent legal counsel) that Indemnitee
has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that Indemnitee has not met the applicable standard of conduct. 
 (e) Indemnitee shall be deemed to have acted in good faith if Indemnitee’s action is based on the records or books of account of the Enterprise (as defined in Section 13(e)),
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/or actions, or failure to act, of any director, officer, agent or employee of
the Enterprise shall 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 shall 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 shall 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 this Section 6 to determine whether Indemnitee is entitled to indemnification shall not have made a determination within sixty (60) days after receipt by the Company of the request therefor, the requisite determination of
entitlement to indemnification shall be deemed to have been made and Indemnitee shall 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; provided, however, that such 60-day period may be extended for a reasonable time, not to exceed an additional thirty (30) days, if the person, persons or entity making such determination with respect to entitlement to indemnification in
good faith requires such additional time to obtain or evaluate documentation and/or information relating thereto; and provided, further, that the foregoing provisions of this Section 6(f) shall not apply if the
determination of entitlement to indemnification is to be made by the stockholders pursuant to Section 6(b) of this Agreement and if (A) within fifteen (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 thereof to be held within seventy-five (75) days after such receipt
and such 

  
 6 








 
determination is made thereat or (B) a special meeting of stockholders is called within fifteen (15) days after such receipt for the purpose of making such determination, such meeting
is held for such purpose within sixty (60) days after having been so called and such determination is made thereat. 

(g) Indemnitee shall cooperate with the person, persons or entity making such determination with respect to Indemnitee’s
entitlement to indemnification, including providing to such person, persons or entity upon 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 shall 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 shall be borne by the Company
(irrespective of the determination as to Indemnitee’s entitlement to indemnification) and the Company hereby 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 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 Proceeding with or without payment of money or other consideration) it shall be presumed that Indemnitee has been successful on the merits or otherwise in such Proceeding. Anyone seeking to overcome this presumption shall 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 therein, by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall 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 of this Agreement that Indemnitee is not entitled to indemnification under this Agreement; (ii) advancement of Expenses is not timely made pursuant to Section 5 of this Agreement;
(iii) no determination of entitlement to indemnification is made pursuant to Section 6(b) of this Agreement within ninety (90) days after receipt by the Company of the request for indemnification; (iv) payment of
indemnification is not made pursuant to this Agreement within ten (10) days after receipt by the Company of a written request therefor; or (v) payment of indemnification is not made within ten (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 of this Agreement, Indemnitee shall be entitled to an adjudication in any


  
 7 








 
court of competent jurisdiction of Indemnitee’s entitlement to such indemnification. Indemnitee shall commence such proceeding seeking an adjudication within one hundred eighty
(180) days following the date on which Indemnitee first has the right to commence such proceeding pursuant to this Section 7(a). The Company shall not oppose Indemnitee’s right to seek any such adjudication. 

(b) In the event that a determination shall have been made pursuant to Section 6(b) of this Agreement that Indemnitee
is not entitled to indemnification, any judicial proceeding commenced pursuant to this Section 7 shall be conducted in all respects as a de novo trial on the merits, and Indemnitee shall not be prejudiced by reason of the adverse
determination under Section 6(b). 
 (c) If a determination shall have been made pursuant to
Section 6(b) of this Agreement that Indemnitee is entitled to indemnification, the Company shall 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 shall pay on his or her
behalf, in advance, any and all expenses (of the types described in the definition of “Expenses” in Section 13(g) of this Agreement) 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 shall 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 shall stipulate in any such court that the Company is bound by all the provisions of this Agreement. The Company shall indemnify Indemnitee against any and all Expenses and, if requested by Indemnitee, shall (within ten
(10) days after receipt by the Company of a written request therefor) 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 shall be required to be made prior to the final disposition of the Proceeding. 

  
 8 








 8. NON-EXCLUSIVITY, SURVIVAL OF
RIGHTS, ETC. 
 (a) The rights of indemnification as provided by this Agreement shall
not be deemed exclusive of any other rights to which Indemnitee may at any time be entitled under applicable law, the organizational documents of the Company, any other agreement with the Company, a vote of the Company’s stockholders, a
resolution of the Board or otherwise. No amendment, alteration or repeal of this Agreement or of any provision hereof shall 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 any applicable law, whether by statute or judicial decision, permits greater indemnification than would be afforded currently under the
Company’s organizational documents and this Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change. No right or remedy herein conferred is intended to be
exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment
of any right or remedy hereunder, or otherwise, shall 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 Enterprise, Indemnitee shall be covered by such policy or policies 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 hereof, the Company has directors’ and officers’ liability insurance in effect, the Company shall give prompt notice of the commencement of such proceeding to the
insurers in accordance with the procedures set forth in the respective policies. The Company shall 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 hereby
acknowledges that Indemnitee may have certain rights to indemnification, advancement of expenses and/or insurance provided by the Associated Fund and/or certain of its affiliates (collectively, the “Additional Indemnitors”).
The Company hereby agrees that: (i) it is the indemnitor of first resort (i.e., its obligations to Indemnitee are primary and any obligation of the Additional Indemnitors (or any insurance carrier providing insurance coverage purchased by any
Additional Indemnitor) to advance expenses or to provide indemnification for the same expenses or liabilities incurred by Indemnitee are secondary); (ii) it shall be required to advance the full amount of expenses incurred by Indemnitee and
shall 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 and the organizational documents of the Company, without
regard to any rights Indemnitee may have against the Additional Indemnitors (or any insurance carrier providing insurance coverage purchased by any Additional Indemnitor); and (iii) it irrevocably waives, relinquishes and releases the
Additional Indemnitors from any and all claims against the Additional 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 Additional
Indemnitors on behalf of  

  
 9 








 
Indemnitee with respect to any claim for which Indemnitee has sought indemnification from the Company shall affect the foregoing and the Additional Indemnitors shall have a right of
indemnification and/or be subrogated to the full 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 Additional Indemnitors are express third party
beneficiaries of the terms of this Section 8(c). 
 (d) Except as provided in Section 8(c) above,
in the event of any payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee (other than against the Additional Indemnitors), who shall 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) above, the Company shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable hereunder if and to the extent
that Indemnitee has otherwise actually received payment of such amounts under any insurance policy, contract, other agreement or otherwise. 
 (f) Except as provided in Section 8(c) above, the Company’s obligation to indemnify or advance Expenses hereunder to Indemnitee who is or was serving at the request of the Company
as a director, officer, employee or agent of any Enterprise other than the Company shall be reduced by any amount Indemnitee has actually received as indemnification or advancement of expenses from such other Enterprise. 

9. EXCEPTION TO RIGHT OF INDEMNIFICATION. Notwithstanding
any provision in this Agreement, the Company shall not be obligated under this Agreement to provide any indemnification in connection with any claim made against Indemnitee: (i) 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 shall not affect the rights of
Indemnitee or the Additional Indemnitors set forth in Section 8(c); (ii) 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; or (iii) 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 (A) the Board authorized the Proceeding (or any part of any Proceeding) prior to its initiation or (B) the Company
provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law. 
 10.
DURATION OF AGREEMENT. All agreements and obligations of the Company contained herein shall continue until the date that is six (6) years after the date upon which
Indemnitee’s Corporate Status terminates and shall continue thereafter so long as Indemnitee shall be subject to any Proceeding (or any proceeding commenced under Section 7 hereof) 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 liability or expense is incurred for which indemnification can be provided under this Agreement. This Agreement shall be binding upon and inure to the benefit of and be
enforceable  

  
 10 









 
by the parties hereto 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 hereunder 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.

of this Agreement but excluding one initiated by an Indemnitee pursuant to Section 7 of this Agreement to enforce his or her rights under this Agreement), whether brought by or in the right of the Company or otherwise and whether civil,
criminal, administrative or investigative, in which Indemnitee was, is or will be involved as a party or otherwise, by reason of the fact that Indemnitee is or was an officer or director of the Company, by reason of any action taken by him or 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
Agreement. 
 14. SEVERABILITY. The invalidity or unenforceability of any provision hereof shall in no way
affect the validity or enforceability of 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 shall 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 shall be binding unless executed in writing by both of the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions hereof (whether or not similar) nor
shall such waiver constitute a continuing waiver. 
 16. NOTICE BY
INDEMNITEE. Indemnitee agrees to promptly 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 hereunder. The failure to so notify the Company shall 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.
