 Exhibit 10.6 
 INDEMNIFICATION AGREEMENT 
 This Indemnification Agreement, dated as
of                          , 2011, is made by and between TVAX Biomedical, Inc., a Delaware corporation (the
“Corporation”), and                  (the “Indemnitee”). 
 RECITALS 
 A. The Corporation recognizes that competent and experienced
persons are increasingly reluctant to serve or to continue to serve as directors or officers of corporations unless they are protected by comprehensive liability insurance or indemnification, or both, due to increased exposure to litigation costs
and risks resulting from their service to such corporations, and due to the fact that the exposure frequently bears no reasonable relationship to the compensation of such directors and officers; 

B. The statutes and judicial decisions regarding the duties of directors and officers are often difficult to apply, ambiguous, or
conflicting, and therefore fail to provide such directors and officers with adequate, reliable knowledge of legal risks to which they are exposed or information regarding the proper course of action to take; 

C. The Corporation and Indemnitee recognize that plaintiffs often seek damages in such large amounts and the costs of litigation may be
so enormous (whether or not the case is meritorious), that the defense and/or settlement of such litigation is often beyond the personal resources of directors and officers and the exposure from such litigation frequently bears no reasonable
relationship to the compensation of such directors and officers; 
 D. The Corporation believes that it is unfair for its
directors and officers to assume the risk of huge judgments and other expenses which may occur in cases in which the director or officer received no personal profit and in cases where the director or officer was not culpable; 

E. The Corporation, after reasonable investigation, has determined that the liability insurance coverage presently available to the
Corporation may be inadequate in certain circumstances to cover all possible exposure for which Indemnitee should be protected. The Corporation believes that the interests of the Corporation and its stockholders would best be served by a combination
of such insurance and the indemnification by the Corporation of the directors and officers of the Corporation; 
 F. The
Corporation’s Bylaws require the Corporation to indemnify its directors and officers to the fullest extent permitted by the Delaware General Corporation Law (the “DGCL”). The Bylaws expressly provide that the indemnification
provisions set forth therein are not exclusive, and contemplate that contracts may be entered into between the Corporation and its directors and officers with respect to indemnification; 

G. Section 145 of the DGCL (“Section 145”), under which the Corporation is organized, empowers the Corporation to
indemnify its officers, directors, employees and agents by agreement and to indemnify persons who serve, at the request of the Corporation, as the directors, officers, employees or agents of other corporations or enterprises, and expressly provides
that the indemnification provided by Section 145 is not exclusive; 

  
 1 

 H. Section 102(b)(7) of the DGCL allows a corporation to include in its certificate of
incorporation a provision limiting or eliminating the personal liability of a director for monetary damages in respect of claims by shareholders and corporations for breach of certain fiduciary duties, and the Corporation has so provided in its
Certificate of Incorporation that each Director shall be exculpated from such liability to the maximum extent permitted by law; 

I. The Corporation desires to provide the Indemnitee with specific contractual assurances of the Indemnitee’s rights to full
indemnification against litigation risks and reasonable expenses (regardless, among other things, of any amendment to or revocation of the Certificate of Incorporation and Bylaws or any change in the ownership of the Corporation or the composition
of its Board of Directors) and, to the extent insurance is available, the coverage of the Indemnitee under the Corporation’s directors’ and officers’ liability insurance policies; 

J. The Board of Directors has determined that contractual indemnification as set forth herein is not only reasonable and prudent but also
promotes the best interests of the Corporation and its stockholders; 
 K. The Corporation desires and has requested Indemnitee
to serve or continue to serve as a director or officer of the Corporation free from undue concern for unwarranted claims for damages arising out of or related to such services to the Corporation; and 

L. Indemnitee is willing to serve, continue to serve or to provide additional service for or on behalf of the Corporation on the
condition that he is furnished the indemnity provided for herein. 
 AGREEMENT 

NOW, THEREFORE, in consideration of the mutual covenants and agreements set forth below, and other good and valuable consideration, the
receipt and adequacy of which are hereby acknowledged, the parties hereto, intending to be legally bound, hereby agree as follows: 
 Section 1. Certain Definitions. For purposes of this Agreement, the following definitions shall apply: 
 (a) The term “Proceeding” shall be broadly construed and shall include, without limitation, the investigation, preparation, prosecution, defense, settlement, arbitration and appeal of, and the
giving of testimony in, any threatened, pending or completed claim, action, suit, proceeding, or arbitration, whether civil, criminal, administrative, investigative, appellate or arbitral, and whether formal or informal. 

(b) The phrase “by reason of the fact that Indemnitee is or was a director or officer of the Corporation, or is or was serving at

act.

 (c) The term “Expenses” shall be broadly and reasonably construed and shall
include, without limitation, all direct and indirect expenses, costs or charges of any type or nature whatsoever (including, without limitation, all attorneys’ fees and related disbursements, appeal bonds, other out-of-pocket costs and
reasonable compensation for time spent by Indemnitee for which Indemnitee is not otherwise compensated by the Corporation or any third party, provided that the rate of compensation and estimated time involved is approved by the Corporation’s
Board of Directors, which approval shall not be unreasonably withheld, conditioned or delayed), actually and reasonably incurred by Indemnitee in connection with the investigation, preparation, prosecution, defense, settlement, arbitration or appeal
of, or the giving of testimony in, a Proceeding or establishing or enforcing a right to indemnification under this Agreement, the Corporation’s Certificate of Incorporation or Bylaws, Section 145 of the General Corporation Law of the State
of Delaware or otherwise.

 (e) The term “Corporation”
shall include, without limitation and in addition to the resulting corporation, any constituent corporation or any Other Enterprise (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence
had continued, would have had power and authority to indemnify its directors, officers, and employees or agents, so that any person who is or was a director or officer of such constituent corporation or Other Enterprise, or is or was serving at the
request of such constituent corporation as a director, officer, employee or agent of any Other Enterprise, shall stand in the same position under the provisions of this Agreement with respect to the resulting or surviving corporation as he or she
would have with respect to such constituent corporation or Other Enterprise as if its separate existence had continued. 
 (f)
The term “Other Enterprise” shall include, without limitation, any other corporation, partnership, joint venture, trust or employee benefit plan. 
 (g) The phrase “serving at the request of the Corporation”, or any substantially similar phrase, shall include, without limitation, any service as a director or officer of the Corporation which
involves services as a director, officer, employee or agent with respect to any Other Enterprise, including any employee benefit plan. 
 (h) A person who acted in good faith and in a manner such person reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted
in a manner “not opposed to the best interests of the Corporation” as referred to in this Agreement. 

  
 3 

 (i) The term “defense” shall include investigations of any Proceeding, appeals of
any Proceeding and defensive assertion of any cross -claim or counterclaim. 
 (j) The term “Independent Counsel”
means a law firm, or a member of a law firm, that is experienced in matters of corporation law and neither presently is, nor in the past five years has been, retained to represent: (i) the Corporation or Indemnitee in any matter material to
either such party (other than with respect to matters concerning Indemnitee under this Agreement, or of other indemnitees under similar indemnification agreements), or (ii) any other party to the Proceeding giving rise to a claim for
indemnification hereunder. Notwithstanding the foregoing, the term “Independent Counsel” shall not include any person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in
representing either the Corporation or Indemnitee in an action to determine Indemnitee’s rights under this Agreement. The Corporation agrees to pay the reasonable fees of the Independent Counsel arising out of or relating to this Agreement or
its engagement pursuant hereto. 
 (k) The term “Change of Control” means (i) an acquisition by any person
(within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) of beneficial ownership of twenty percent (20%) or more of the combined voting power of the
Corporation’s then outstanding voting securities; (ii) during any period of two consecutive years, individuals who at the beginning of such period constitute the Board of Directors of the Corporation and any new director whose election by
the Board of Directors or nomination for election by the Corporation’s stockholders was approved by a vote of at least two-thirds (2/3) of the directors then still in office who either were directors at the beginning of the period or whose
election or nomination for election was previously so approved, cease for any reason to constitute a majority thereof; or (iii) the consummation of a merger or consolidation involving the Corporation if the stockholders of the Corporation,
immediately before such merger or consolidation, do not own, immediately following such merger or consolidation, more than eighty percent (80%) of the combined voting power of the outstanding voting securities of the resulting entity in
substantially the same proportion as their ownership of voting securities immediately before such merger or consolidation, (iv) the consummation of the sale or other disposition of all or substantially all of the assets of the Corporation,
(v) approval by the stockholders of the Corporation of a complete liquidation or dissolution of the Corporation or (vi) the occurrence of any other event of a nature that would be required to be reported in response to either
Item 5.01 of Form 8-K or Item 6(e) of Schedule 14A of Regulation 14A (or a response to any similar item on any similar schedule or form promulgated under the Exchange Act), whether or not the Corporation is then subject to such reporting
requirement. Notwithstanding the foregoing, a Change of Control shall not be deemed to occur solely because twenty percent (20%) or more of the then outstanding voting securities is acquired by (i) a trustee or other fiduciary holding
securities under one or more employee benefit plans maintained by the Corporation or any of its subsidiaries or (ii) any entity that, immediately prior to such acquisition, is owned directly or indirectly by the stockholders of the Corporation
in the same proportion as their ownership of shares in the Corporation immediately prior to such acquisition.

 Section 2. Indemnification. 

(a) Subject to Sections 4, 6 and 8 of this Agreement, to the fullest extent not prohibited by the laws of the State of Delaware, as the
same now exists or may hereafter be amended (but only to the extent any such amendment permits the Corporation to provide broader indemnification rights than such law permitted the Corporation to provide prior to such amendment), the Corporation
shall indemnify, defend and hold harmless, Indemnitee if Indemnitee was or is a party or is threatened to be made a party to, or a witness of, or is otherwise involved in, any Proceeding by reason of the fact that Indemnitee is or was or has agreed
to serve as a director or officer of the Corporation, or is or was serving at the Corporation’s request as a director, officer, employee or agent of any Other Enterprise, or by reason of any action taken or alleged to have been taken, or
omitted to be taken or alleged to be omitted to be taken, in such capacity. 
 (b) The indemnification provided by this
Section 2 shall be from and against Expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with such Proceeding, but shall only be provided if
Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal Proceeding, had no reasonable cause to believe Indemnitee’s
conduct was unlawful. 
 (c) Notwithstanding the foregoing provisions of this Section 2, in the case of any Proceeding by
or in the right of the Corporation to procure a judgment in its favor by reason of the fact that Indemnitee is or was a director or officer of the Corporation, or is or was serving at the Corporation’s request as a director, officer, employee
or agent of any Other Enterprise, no indemnification shall be made in respect of any claim, issue or matter as to which Indemnitee shall have been adjudged to be liable to the Corporation unless, and only to the extent that, the Kansas Court
(referred to in Section 20 of this Agreement) shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, Indemnitee is fairly and reasonably entitled to indemnity for such
Expenses which the Kansas Court shall deem proper. 
 (d) The termination of any Proceeding by judgment, order, settlement,
conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that Indemnitee did not act in good faith and in a manner which Indemnitee reasonably believed to be in or not opposed to the best interests
of the Corporation, and, with respect to any criminal Proceeding, had reasonable cause to believe that Indemnitee’s conduct was unlawful. 
 Section 3. Successful Defense; Partial Indemnification. To the extent that Indemnitee has been successful on the merits or otherwise in defense of any Proceeding referred to in Section 2
hereof or in defense of any claim, issue or matter therein, Indemnitee shall be indemnified against Expenses actually and reasonably incurred in connection therewith. For purposes of this Agreement and without limiting the foregoing, if any
Proceeding is disposed of, on the merits or otherwise (including a disposition without prejudice), without (i) the disposition being adverse to Indemnitee, (ii) an adjudication that Indemnitee was liable to the Corporation, (iii) a
plea of guilty or nolo contendere by Indemnitee, (iv) an adjudication that Indemnitee did 

  
 5 

 
not act in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Corporation, and (v) with respect to any criminal Proceeding, an
adjudication that Indemnitee had reasonable cause to believe Indemnitee’s conduct was unlawful, Indemnitee shall be considered for the purposes hereof to have been wholly successful with respect thereto. 

If Indemnitee is entitled under any provision of this Agreement to indemnification by the Corporation for some or a portion of the
Expenses, judgments, fines or amounts paid in settlement actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with any Proceeding, or in defense of any claim, issue or matter therein, and any appeal therefrom
but not, however, for the total amount thereof, the Corporation shall nevertheless indemnify Indemnitee for the portion of such Expenses, judgments, fines or amounts paid in settlement to which Indemnitee is entitled. Any necessary determination
regarding allocation or apportionment of Expenses between successful and unsuccessful claims, issues or matters shall be made by the person, persons or entity empowered or selected under Section 4(a) to determine whether Indemnitee is entitled
to indemnification. 
 Section 4. Determination That Indemnification Is Proper. 

(a) Any indemnification hereunder shall (unless otherwise ordered by a court) be made by the Corporation unless a determination is made
that indemnification of such person is not proper in the circumstances because he or she has not met the applicable standard of conduct set forth in Section 2(b) hereof. Any such determination shall be made (i) by a majority vote of the
directors who are not parties to the Proceeding in question (“disinterested directors”), even if less than a quorum, (ii) by a majority vote of a committee of disinterested directors designated by majority vote of disinterested
directors, even if less than a quorum, (iii) by a majority vote of a quorum of the outstanding shares of stock of all classes entitled to vote on the matter, voting as a single class, which quorum shall consist of stockholders who are not at
that time parties to the Proceeding in question, (iv) by Independent Counsel, or (v) by a court of competent jurisdiction; provided, however, that following a Change of Control of the Corporation, any determinations, whether
arising out of acts, omissions or events occurring prior to or after the Change of Control of the Corporation, shall be made by Independent Counsel selected in the manner described in Section 4(b). Such Independent Counsel shall determine as
promptly as practicable whether and to what extent Indemnitee would be permitted to be indemnified under applicable law and shall render a written opinion to the Corporation and to Indemnitee to such effect. 

(b) If the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 4(a) hereof, the
Independent Counsel shall be selected as provided in this Section 4(b). The Independent Counsel shall be selected by the Board of Directors. Indemnitee may, within ten (10) days after such written notice of selection shall have been given,
deliver to the Corporation, as the case may be, 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 1 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 in proper form, the Independent Counsel 

  
 6 

 
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 twenty (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 Corporation or Indemnitee may petition the Kansas Court for
resolution of any objection which shall have been made by the Indemnitee to the Corporation’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 4(a) hereof. The Corporation shall pay any and all reasonable fees and expenses
of Independent Counsel incurred by such Independent Counsel in connection with acting pursuant to Section 4(a) hereof, and the Corporation shall pay all reasonable fees and expenses incident to the procedures of this Section 4(b)
regardless of the manner in which such Independent Counsel was selected or appointed. 
 Section 5. Advance Payment of
Expenses; Notification and Defense of Claim. 
 (a) In the event that the Corporation does not assume the defense pursuant
to Section 5(c) of any Proceeding of which the Corporation receives notice under this Agreement, any Expenses incurred by Indemnitee in defending a Proceeding, or in connection with an enforcement action pursuant to Section 6(b), shall be
paid by the Corporation to Indemnitee in advance of the final disposition of such Proceeding as soon as practicable but in any event no later than twenty (20) days after receipt by the Corporation of (i) a statement or statements from
Indemnitee requesting such advance or advances from time to time, and (ii) an undertaking by or on behalf of Indemnitee to repay such amount or amounts, only if, and to the extent that, there is a final judicial determination (as to which all
rights of appeal therefrom have been exhausted or lapsed) that Indemnitee is not entitled to be indemnified by the Corporation as authorized by this Agreement or otherwise. Such undertaking shall be accepted without reference to the financial
ability of Indemnitee to make such repayment. Advances shall be unsecured and interest-free. Notwithstanding the foregoing, the obligation of the Corporation to advance Expenses pursuant to this Section 5, its Certificate of Incorporation, its
Bylaws or otherwise, shall be subject to the condition that, if, when and to the extent that the Corporation determines that Indemnitee would not be permitted to be indemnified under applicable law, the Corporation shall be reimbursed within sixty
(60) days of such determination, by Indemnitee (who hereby agrees to reimburse the Corporation) for such amounts previously paid by the Corporation pursuant to this Section 5; provided, however, that if Indemnitee has commenced or
thereafter commences legal proceedings in a court of competent jurisdiction to secure a determination that Indemnitee should be indemnified under applicable law, any determination made by the Corporation that Indemnitee would not be permitted to be
indemnified under applicable law shall not be binding and Indemnitee shall not be required to reimburse the Corporation for any advance of Expenses until a final judicial determination is made with respect thereto (as to which all rights of appeal
therefrom have been exhausted or lapsed). 
 (b) Promptly after receipt by Indemnitee of notice of the commencement of any
Proceeding, Indemnitee shall, if a claim thereof is to be made against the Corporation hereunder, notify the Corporation of the commencement thereof. The failure to promptly notify the Corporation of the commencement of the Proceeding, or
Indemnitee’s request for indemnification, will not relieve the Corporation from any liability that it may have to Indemnitee hereunder, except to the extent the Corporation is prejudiced in its defense of such Proceeding as a result of such
failure. 
  

  
 7 

 (c) In the event the Corporation shall be obligated to pay the Expenses of Indemnitee with
respect to a Proceeding as provided in this Agreement, its Certificate of Incorporation, its Bylaws or otherwise, the Corporation, if appropriate, shall be entitled to assume the defense of such Proceeding, with counsel reasonably acceptable to
Indemnitee, upon the delivery to Indemnitee of written notice of its election to do so. After delivery of such notice, approval of such counsel by Indemnitee and the retention of such counsel by the Corporation, the Corporation will not be liable to
Indemnitee under this Agreement for any fees of counsel subsequently incurred by Indemnitee with respect to the same Proceeding, provided that (i) Indemnitee shall have the right to employ Indemnitee’s own counsel in such Proceeding at
Indemnitee’s expense and (ii) if (1) the employment of counsel by Indemnitee has been previously authorized in writing by the Corporation, (2) counsel to the Corporation or Indemnitee shall have reasonably concluded that there
may be a conflict of interest or position, or reasonably believes that a conflict is likely to arise, on any significant issue between the Corporation and Indemnitee in the conduct of any such defense, (3) after a Change of Control, the
employment of counsel by Indemnitee has been approved by the Independent Counsel or (4) the Corporation shall not, in fact, have employed counsel to assume the defense of such Proceeding, then the fees and expenses of Indemnitee’s counsel
shall be at the expense of the Corporation, except as otherwise provided by this Agreement. The Corporation shall not be entitled, without the consent of Indemnitee, to assume the defense of any claim brought by or in the right of the Corporation or
as to which counsel for the Corporation or Indemnitee shall have reasonably made the conclusion provided for in clause (2) of the proviso in the immediately preceding sentence. 

(d) Notwithstanding any other provision of this Agreement to the contrary, to the extent that Indemnitee is, by reason of
Indemnitee’s corporate status with respect to the Corporation or any Other Enterprise which Indemnitee is or was serving or has agreed to serve at the request of the Corporation, a witness or otherwise participates in any Proceeding at a time
when Indemnitee is not a party in the Proceeding, the Corporation shall indemnify Indemnitee against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith. 

Section 6. Procedure for Indemnification. 
 (a) To obtain indemnification (other than as provided otherwise herein) under this Agreement, Indemnitee shall promptly submit to the Corporation 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 Corporation shall, promptly upon receipt of such a request for
indemnification, advise the Board of Directors in writing that Indemnitee has requested indemnification. 
  

  
 8 

 (b) The determination whether to grant Indemnitee’s indemnification request (whether
made by the Board of Directors or one of its committees, Independent Counsel, or the Corporation’s stockholders) shall be made promptly, and in any event within sixty (60) days following receipt of a request for indemnification pursuant to
Section 6(a). The right to indemnification as granted by Section 2 of this Agreement shall be enforceable by Indemnitee in any court of competent jurisdiction if the Corporation denies such request, in whole or in part, or fails to respond
within such sixty-day (60) period. It shall be a defense to any such action (other than an action brought to enforce a claim for the advance of Expenses under Section 5 hereof where the required undertaking, if any, has been received by
the Corporation) that Indemnitee has not met the standard of conduct set forth in Section 2 hereof, but the burden of proving such defense by clear and convincing evidence shall be on the Corporation. Neither the failure of the Corporation
(including its Board of Directors or one of its committees, its Independent Counsel, and its stockholders) to have made a determination prior to the commencement of such action that indemnification of Indemnitee is proper in the circumstances
because Indemnitee has met the applicable standard of conduct set forth in Section 2 hereof, nor the fact that there has been an actual determination by the Corporation (including its Board of Directors or one of its committees, its Independent
Counsel, and its stockholders) that Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that Indemnitee has or has not met the applicable standard of conduct. The Indemnitee’s
Expenses incurred in connection with successfully establishing Indemnitee’s right to indemnification, in whole or in part, in any such Proceeding or otherwise shall also be indemnified by the Corporation. 

(c) The Indemnitee shall be presumed to be entitled to indemnification under this Agreement upon submission of a request for
indemnification pursuant to this Section 6, and the Corporation shall have the burden of proof in overcoming that presumption in reaching a determination contrary to that presumption. Such presumption shall be used as a basis for a
determination of entitlement to indemnification unless the Corporation overcomes such presumption by clear and convincing evidence. 
 (d) The knowledge and/or actions, or failure to act, of any director, officer, agent or employee of the Corporation shall not be imputed to Indemnitee for purposes of determining the right to
indemnification under this Agreement. 
 Section 7. Insurance and Subrogation. 

(a) The Corporation represents that it currently has in effect the following policy or policies of director and officer liability
insurance (the “Insurance Policies”) which names or covers Indemnitee as an insured: 
  

													
	Insurer	  	Policy No.	 	  	Amount	 	  	Deductible	 
	 Carolina Casualty Insurance Company
	  	 	61065021	  	  	$	1,000,000	  	  	$	25,000	  

 (b) So long as Indemnitee shall continue to serve as a director or officer of the Corporation, or shall
continue at the request of the Corporation to serve as a director or officer, employee or agent of any Other Enterprise, and thereafter so long as Indemnitee shall be subject 

  
 9 

 
to any possible claim or is a party or is threatened to be made a party to any Proceeding, by reason of the fact that Indemnitee is or was a director or officer of the Corporation, or is or was
serving in any of said other capacities at the request of the Corporation, the Corporation shall be required to maintain the Insurance Policies in effect or to obtain policies of directors’ and officers’ liability insurance from
established and reputable insurers with coverage in at least the amount or amounts as prescribed by the Insurance Policies and which provides the Indemnitee with substantially the same rights and benefits as the Insurance Policies, and which
coverage, rights and benefits shall, in any event, be as favorable to Indemnitee as are accorded to the most favorably insured of the Corporation’s directors or officers, as the case may be (“Comparable D&O Insurance”) unless, in
the reasonable business judgment of the Board of Directors of the Corporation as it may exist from time to time, either (i) the premium cost for such Insurance Policies or Comparable D&O Insurance is disproportionate to the amount of
coverage provided, or (ii) the coverage provided by such Insurance Policies or Comparable D&O Insurance is so limited by exclusions that there is insufficient benefit provided by such director and officer liability insurance; provided,
however, that in the event that the Board of Directors makes such a determination, the Corporation shall provide notice to Indemnitee no less than ninety (90) days prior to the lapse or termination of coverage under the Insurance Policies or
Comparable D&O Insurance. 
 (c) If, at the time of the receipt of a notice of a claim pursuant to the terms hereof, the
Corporation has director and officer liability insurance in effect, the Corporation shall give prompt notice of the commencement of such claim, and any Proceeding in which such claim is asserted, to the insurers in accordance with the procedures set
forth in the respective policies. The Corporation 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 claim or Proceeding in accordance with the
terms of such policies. The failure or refusal of any such insurer to pay any such amount shall not affect or impair the obligations of the Corporation under this Agreement. 
 (d) In the event of any payment by the Corporation under this Agreement, the Corporation shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee with respect to
any insurance policy, 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 Corporation to bring suit to enforce such rights in accordance with
the terms of such insurance policy. The Corporation shall pay or reimburse all Expenses actually and reasonably incurred by Indemnitee in connection with such subrogation. 
 (e) The Corporation shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable hereunder (including, but not limited to, Expenses, judgments, fines, ERISA excise taxes
or penalties, and amounts paid in settlement) if and to the extent that Indemnitee has otherwise actually received such payment under the Corporation’s Certificate of Incorporation or Bylaws, or any insurance policy, contract, agreement or
otherwise. 
 (f) The Corporation’s obligation to indemnify or advance Expenses hereunder to Indemnitee who is or was
serving at the request of the Corporation as a director, officer, employee or agent of any Other Enterprise shall be reduced by any amount Indemnitee has actually received as indemnification or advancement of Expenses from such Other Enterprise.

  
 10 

 Section 8. Limitation on Indemnification. Notwithstanding any other
provision herein to the contrary, the Corporation shall not be obligated pursuant to this Agreement: 
 (a) Claims
Initiated by Indemnitee. To indemnify or advance expenses to Indemnitee with respect to a Proceeding (or part thereof) initiated by Indemnitee, except with respect to a Proceeding brought to establish or enforce a right to indemnification (which
shall be governed by the provisions of Sections 6(b) and 8(b) of this Agreement), unless such Proceeding (or part thereof) was authorized or consented to by the Board of Directors of the Corporation or the Proceeding was commenced following a Change
of Control. 
 (b) Action for Indemnification. To indemnify Indemnitee for any Expenses incurred by Indemnitee with
respect to any Proceeding instituted by Indemnitee to enforce or interpret this Agreement, unless Indemnitee is successful in establishing Indemnitee’s right to indemnification in such Proceeding, in whole or in part, or unless and to the
extent that the court in such Proceeding shall determine that, despite Indemnitee’s failure to establish his or her right to indemnification, Indemnitee is entitled to indemnity for such Expenses; provided, however, that nothing in this
Section 8(b) is intended to limit the Corporation’s obligation with respect to the advancement of Expenses to Indemnitee in connection with any such Proceeding instituted by Indemnitee to enforce or interpret this Agreement, as provided in
Section 5 hereof. 
 (c) Certain Statutory Violations. To indemnify Indemnitee on account of any Proceeding with
respect to which final judgment is rendered against Indemnitee for (i) payment or an accounting of profits arising from the purchase or sale by Indemnitee of securities in violation of Section 16(b) of the Exchange Act or any similar
successor statute, or (ii) any reimbursement of the Corporation by the Indemnitee of any bonus or other incentive-based or equity-based compensation or of any profits realized by the Indemnitee from the sale of securities of the Corporation, as
required in each case under the Exchange Act (including any such reimbursements that arise from an accounting restatement of the Corporation pursuant to Section 304 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), or the
payment to the Corporation of profits arising from the purchase and sale by Indemnitee of securities in violation of Section 306 of the Sarbanes-Oxley Act). 
 (d) Non-compete and Non-disclosure. To indemnify Indemnitee in connection with Proceedings or claims involving the enforcement of non-compete and/or non-disclosure agreements or the non-compete
and/or non-disclosure provisions of employment, consulting or similar agreements the Indemnitee may be a party to with the Corporation, or any subsidiary of the Corporation or any Other Enterprise. 

Section 9. Mutual Acknowledgement. Both the Corporation and the Indemnitee acknowledge that in certain instances, federal law
or applicable public policy may prohibit the Corporation from indemnifying its directors, officers, employees, agents or fiduciaries under this Agreement or otherwise. The Indemnitee understands and acknowledges that the Corporation has undertaken
or may be required in the future to undertake with the Securities and Exchange Commission to submit the question of indemnification to a court in certain circumstances for a determination of the Corporation’s right under public policy to
indemnify the Indemnitee.

 Section 10. Certain Settlement Provisions. The Corporation shall have no
obligation to indemnify Indemnitee under this Agreement for amounts paid in settlement of any Proceeding without the Corporation’s prior written consent, which shall not be unreasonably withheld, conditioned or delayed; provided,
however, that if a Change of Control has occurred, the Corporation shall be liable for indemnification of Indemnitee for amounts paid in settlement if the Independent Counsel has approved the settlement. The Corporation shall not settle any
Proceeding in any manner that would impose any fine or other obligation on Indemnitee without Indemnitee’s prior written consent, which shall not be unreasonably withheld, conditioned or delayed. 

Section 11. Savings Clause. If any provision or provisions of this Agreement shall be invalidated on any ground by any court
of competent jurisdiction, then the Corporation shall nevertheless indemnify Indemnitee as to Expenses, judgments, fines and amounts paid in settlement with respect to any Proceeding, including an action by or in the right of the Corporation, to the
full extent permitted by any applicable portion of this Agreement that shall not have been invalidated and to the full extent permitted by applicable law. 
 Section 12. Contribution. In order to provide for just and equitable contribution in circumstances in which the indemnification provided for herein is held by a court of competent jurisdiction
to be unavailable to Indemnitee in whole or in part, it is agreed that, in such event, the Corporation shall, to the fullest extent permitted by law, contribute to the payment of Indemnitee’s Expenses, judgments, fines and amounts paid in
settlement with respect to any Proceeding, or any claims, issues or matters in such Proceeding, in an amount that is just and equitable in the circumstances, taking into account, among other things, contributions by other directors and officers of
the Corporation or others pursuant to indemnification agreements or otherwise; provided, that, without limiting the generality of the foregoing, such contribution shall not be required where such holding by the court is due to (i) the failure
of Indemnitee to meet the standard of conduct set forth in Section 2 hereof, or (ii) any limitation on indemnification set forth in Section 7(e), 8, 9 or 10 hereof. 

Section 13. Form and Delivery of Communications. All notices and other communications given or made pursuant to this
Agreement shall be in writing and shall be deemed effectively given: (i) upon personal delivery to the party to be notified, (ii) if sent via facsimile, upon confirmation of facsimile transfer or, if sent via electronic mail, upon
confirmation of delivery when directed to the relevant electronic mail address, if sent during normal business hours of the recipient, or if not sent during normal business hours of the recipient, then on the recipient’s next business day,
(iii) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (iv) one (1) day after deposit with a nationally recognized overnight courier, specifying next day
delivery, with written verification of receipt. All communications shall be sent to the address, facsimile number or electronic mail address set forth below, or to such other address, facsimile number or electronic mail address as may have been
furnished hereafter to Indemnitee by the Corporation or to the Corporation by Indemnitee, as the case may be.

 [                                 
           ] 
 Section 14. Nonexclusivity. The
provisions for indemnification, advancement of Expenses and contribution set forth in this Agreement shall not be deemed exclusive of any other rights which Indemnitee may have under any provision of law, the Corporation’s Certificate of
Incorporation or Bylaws, in any court in which a Proceeding is brought, the vote of the Corporation’s stockholders or disinterested directors, other agreements or otherwise, and Indemnitee’s rights hereunder shall continue after Indemnitee
has ceased acting as a director or officer of the Corporation, or ceased serving at the Corporation’s request as a director, officer, employee or agent of any Other Enterprise, and shall inure to the benefit of the heirs, executors,
administrators and legal representatives of Indemnitee. However, no amendment or alteration of the Corporation’s Certificate of Incorporation or Bylaws or any other agreement shall adversely affect the rights provided to Indemnitee under this
Agreement. 
 Section 15. Enforcement. The Corporation shall be precluded from asserting in any judicial
Proceeding that the procedures and presumptions of this Agreement are not valid, binding and enforceable. The Corporation agrees that its obligations set forth in this Agreement are unique and special, and that failure of the Corporation to comply
with the provisions of this Agreement will cause irreparable and irremediable injury to Indemnitee, for which a remedy at law will be inadequate. As a result, in addition to any other right or remedy Indemnitee may have at law or in equity with
respect to breach of this Agreement, Indemnitee shall be entitled to injunctive or mandatory relief directing specific performance by the Corporation of its obligations under this Agreement. 

Section 16. Interpretation of Agreement. It is understood that the parties hereto intend this Agreement to be interpreted and
enforced so as to provide indemnification of, and advancement of Expenses and contribution to, Indemnitee to the fullest extent now or hereafter permitted by law. 

 

  
 13 

 Section 17. Entire Agreement. This Agreement and the documents expressly
referred to herein constitute the entire agreement between the parties hereto with respect to the matters covered hereby, and any other prior or contemporaneous oral or written understandings or agreements with respect to the matters covered hereby
are expressly superseded by this Agreement. 
 Section 18. Modification and Waiver. No supplement, modification 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 provision hereof (whether or not
similar) nor shall such waiver constitute a continuing waiver. 
 Section 19. Successor and Assigns. All of the
terms and provisions of this Agreement shall be binding upon, shall inure to the benefit of and shall be enforceable by the parties hereto and their respective successors, assigns, heirs, executors, administrators and legal representatives. The
Corporation shall require and cause any direct or indirect successor (whether by purchase, merger, consolidation or otherwise) to all or substantially all of the business or assets of the Corporation, by written agreement in form and substance
reasonably satisfactory to Indemnitee, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Corporation would be required to perform if no such succession had taken place. This Agreement shall
continue in effect regardless of whether Indemnitee continues to serve as a director, officer, employee, agent of fiduciary (as applicable) of the Corporation or of any Other Enterprise. 

Section 20. Service of Process and Venue. For purposes of any Proceedings to enforce this Agreement, or otherwise arising out
of or in connection with this Agreement, the Corporation and Indemnitee hereby irrevocably and unconditionally (i) agree that such Proceeding shall be brought only in the District Court of Johnson County, Kansas or, provided there is subject
matter jurisdiction, in the United States District Court for the District of Kansas (the “Kansas Court”), and not in any other forum, (ii) consent, and agree not to object to, personal jurisdiction in the Kansas Court for any such
Proceeding, (iii) consent, and agree not to object to, service of process with respect to any such Proceeding if made in accordance with Section 13 of this Agreement; (iv) consent, and agree not to object to, venue in the Kansas Court
of any such Proceeding. 
 Section 21. Governing Law. This Agreement shall be governed exclusively by and construed
according to the laws of the State of Delaware, as applied to contracts between Delaware residents entered into and to be performed entirely within Delaware. If a court of competent jurisdiction shall make a final determination that the provisions
of the law of any state other than Delaware govern indemnification of, or advancement of Expenses or contribution to, its officers and directors by the Corporation, then the indemnification, advancement of Expenses and contribution provided under
this Agreement shall in all instances be enforceable to the fullest extent permitted under such law, notwithstanding any provision of this Agreement to the contrary. 

  
 14 

 Section 22. Employment Rights. Nothing in this Agreement is intended to
create in Indemnitee any right to employment or continued employment. 
 Section 23. Counterparts. This
Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original and all of which together shall be deemed to be one and the same instrument, notwithstanding that both parties are not signatories to the original
or same counterpart. 
 Section 24. Headings. The section and subsection headings contained in this Agreement are
for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. 
 Section 25.
Section 409A. It is intended that any indemnification payment or advancement of Expenses made hereunder shall be exempt from Section 409A of the Internal Revenue Code of 1986, as amended, and the guidance issued thereunder
(“Section 409A”) pursuant to Treasury Regulation Section 1.409A-1(b)(10). Notwithstanding the foregoing, if any indemnification payment or advancement of Expenses made hereunder shall be determined to be “nonqualified deferred
compensation” within the meaning of Section 409A, then (i) the amount of the indemnification payment or advancement of Expenses during one taxable year shall not affect the amount of the indemnification payments or advancement of
Expenses during any other taxable year, (ii) the indemnification payments or advancement of Expenses must be made on or before the last day of the Indemnitee’s taxable year following the year in which the expense was incurred, and
(iii) the right to indemnification payments or advancement of Expenses hereunder is not subject to liquidation or exchange for another benefit. 
 IN WITNESS WHEREOF, this Agreement has been duly executed and delivered by the parties hereto to be effective as of the date first above written.
