Exhibit 10.6

    

    

    INDEMNIFICATION AGREEMENT

    

    

    This Indemnification Agreement (“Agreement”) is made and entered into as of this [●] day of October, 2020, by and between Lefteris Acquisition Corp., a Delaware corporation
      (the “Company”), and [          ] (“Indemnitee”).

    

    

    WHEREAS, in light of the litigation costs and risks to directors and officers resulting from their service to companies, and the desire of the Company to attract and retain qualified individuals to serve as directors and
      officers, it is reasonable, prudent and necessary for the Company to indemnify and advance expenses on behalf of its directors and/or officers to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company
      free from undue concern regarding such risks;

    

    

    WHEREAS, the Company has requested that Indemnitee serve or continue to serve as a director and/or an officer of the Company and may have requested or may in the future request that Indemnitee serve in other capacities;

    

    

    WHEREAS, one of the conditions that Indemnitee requires in order to serve as a director and/or an officer of the Company is that Indemnitee be so indemnified; and

    

    

    WHEREAS, Indemnitee does not regard the advancement or indemnification protections provided for in the Bylaws or the Certificate of Incorporation to be adequate protection against personal liability.

    

    

    NOW, THEREFORE, in consideration of the premises and the covenants contained herein, the Company and Indemnitee do hereby covenant and agree as follows:

    

    

    1.

    Services by Indemnitee.  Indemnitee agrees to serve as an officer, director, advisor, key employee or in any other capacity of the Company.  Indemnitee may at any time and for any reason
      resign from such position (subject to any contractual obligation the Indemnitee may have under any other agreement).  The foregoing notwithstanding, this Agreement shall continue in full force and effect after Indemnitee has ceased to serve as a
      director, officer, advisor, key employee or in any other capacity of the Company.  This Agreement, however, shall not impose any obligation on Indemnitee or the Company to continue Indemnitee’s service to the Company beyond any period otherwise
      required by law or by other agreements or commitments of the parties, if any.

    

    

    2.

    Indemnification - General.  On the terms and subject to the conditions of this Agreement, the Company shall, to the fullest extent permitted by law, indemnify Indemnitee with respect to, and
      hold Indemnitee harmless from and against, all losses, liabilities, judgments, fines, penalties, costs, amounts paid in settlement, Expenses (as hereinafter defined) and other amounts that Indemnitee incurs and that result from, arise in connection
      with or are by reason of Indemnitee’s Corporate Status (as hereinafter defined) and shall advance Expenses to Indemnitee.  .

    

    

    
      1

      
        


    

    3.

    Indemnity in Third-Party Proceedings.  If in connection with or by reason of Indemnitee’s Corporate Status, Indemnitee was, is, or is threatened to be made, a party to or a participant in any
      Proceeding (as hereinafter defined) other than a Proceeding by or in the right of the Company to procure a judgment in its favor, the Company shall, to the fullest extent permitted by law, indemnify Indemnitee with respect to, and hold Indemnitee
      harmless from and against, all Expenses, liabilities, judgments, penalties, fines and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of such liabilities, judgments,
      penalties, fines and amounts paid in settlement) actually and reasonably incurred by Indemnitee or on behalf of Indemnitee in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee 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 and, in the case of a criminal Proceeding, had no reasonable cause to believe that his or her conduct was unlawful.

    

    

    4.

    Indemnity in Proceedings by or in the Right of the Company.  If in connection with or by reason of Indemnitee’s Corporate Status, Indemnitee was, is, or is threatened to be made, a party to
      or a participant in any Proceeding by or in the right of the Company to procure a judgment in the Company’s favor, the Company shall, to the fullest extent permitted by law, indemnify Indemnitee with respect to, and hold Indemnitee harmless from and
      against, all Expenses actually and reasonably incurred by Indemnitee or on behalf of Indemnitee in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee 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. No indemnification, hold harmless or exoneration for Expenses shall be made under this Section 4 in respect of any claim, issue or matter as to which Indemnitee shall have been finally
      adjudged by a court to be liable to the Company, unless and only to the extent that any court in which the Proceeding was brought or the Delaware Court 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 indemnification, to be held harmless or to exoneration.

    

    

    5.

    Mandatory Indemnification in Case of Successful Defense.  Notwithstanding any other provisions of this Agreement, to the extent that Indemnitee is, by reason of Indemnitee’s Corporate Status,
      a party to (or a participant in) and is successful, on the merits or otherwise, in defense of any Proceeding or any claim, issue or matter therein (including, without limitation, any Proceeding brought by or in the right of the Company), the Company
      shall, to the fullest extent permitted by applicable law, indemnify Indemnitee with respect to, and hold Indemnitee harmless from and against, all Expenses actually and reasonably incurred by Indemnitee or on behalf of Indemnitee in connection
      therewith.  If Indemnitee is not wholly successful in defense of 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, to the fullest extent
      permitted by law, indemnify Indemnitee against all Expenses actually and reasonably incurred by Indemnitee or on behalf of Indemnitee in connection with each successfully resolved claim, issue or matter.  For purposes of this Section 5 and
      without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, on substantive or procedural grounds, or settlement of any such claim prior to a final judgment by a court of competent
      jurisdiction with respect to such Proceeding, shall be deemed to be a successful result as to such claim, issue or matter.

    

    

    
      2

      
        


    

    6.

    Partial Indemnification.  If Indemnitee is entitled under any provision of this Agreement or otherwise to indemnification by the Company for some or a portion of the Expenses, liabilities,
      judgments, penalties, fines and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of such liabilities, judgments, penalties, fines and amounts paid in settlement)
      actually and reasonably incurred by Indemnitee or in connection with a Proceeding or any claim, issue or matter therein, in whole or in part, the Company shall, to the fullest extent permitted by law, indemnify Indemnitee to the fullest extent to
      which Indemnitee is entitled to such indemnification.

    

    

    7.

    Indemnification for Additional Expenses Incurred to Secure Recovery or as Witness.

    

    

    (a)

    The Company shall, to the fullest extent permitted by law, indemnify Indemnitee with respect to, and hold Indemnitee harmless from and against, any and all Expenses and, if requested by Indemnitee,
      shall advance on an as-incurred basis (as provided in Section 8 of this Agreement) such Expenses to Indemnitee, which are actually and reasonably incurred by Indemnitee in connection with any action or proceeding or part thereof brought by
      Indemnitee for (i) indemnification or advance payment of Expenses by the Company under this Agreement, any other agreement, the Certificate of Incorporation or Bylaws of the Company as now or hereafter in effect; or (ii) recovery under any director
      and officer liability insurance policies maintained by the Company.

    

    

    (b)

    To the extent that Indemnitee is, by reason of Corporate Status, a witness (or is forced or asked to respond to discovery requests) in any Proceeding to which Indemnitee is not a party, the Company
      shall, to the fullest extent permitted by law, indemnify Indemnitee with respect to, and hold Indemnitee harmless from and against, and the Company will advance on an as-incurred basis (as provided in Section 8 of this Agreement), all
      Expenses actually and reasonably incurred by Indemnitee or on behalf of Indemnitee in connection therewith.

    

    

    8.

    Advancement of Expenses.  The Company shall, to the fullest extent permitted by law, pay on a current and as-incurred basis all Expenses actually and reasonably incurred by Indemnitee in
      connection with any Proceeding in any way connected with, resulting from or relating to Indemnitee’s Corporate Status.  Such Expenses shall be paid in advance of the final disposition of such Proceeding, without regard to whether Indemnitee will
      ultimately be entitled to be indemnified for such Expenses and without regard to whether an Adverse Determination (as hereinafter defined) has been or may be made, except as contemplated by the last sentence of Section 9(f) of this
      Agreement.  Upon submission by the Indemnitee and receipt by the Company of a request for advancement of Expenses pursuant to Section 9(c) of this Agreement, Indemnitee shall be entitled to advancement of Expenses as provided in this Section
        8, and such advancement of Expenses shall continue until such time (if any) as there is a final non-appealable judicial determination that Indemnitee is not entitled to indemnification.  Indemnitee shall repay such amounts advanced if and to
      the extent that it shall ultimately be determined in a decision by a court of competent jurisdiction from which no appeal can be taken that Indemnitee is not entitled to be indemnified by the Company for such Expenses.  Such repayment obligation
      shall be unsecured and shall not bear interest.  The Company shall not impose on Indemnitee additional conditions to advancement or require from Indemnitee additional undertakings regarding repayment.

    

    

    
      3

      
        


    

    9.

    Indemnification Procedures.

    

    

    (a)

    Notice of Proceeding.  Indemnitee agrees to notify the Company promptly upon being served with any summons, citation, subpoena, complaint, indictment, information or other document relating
      to any Proceeding or matter which may be subject to indemnification or advancement of Expenses hereunder.  Any failure by Indemnitee to notify the Company will relieve the Company of its advancement or indemnification obligations under this Agreement
      only to the extent the Company can establish that such omission to notify resulted in actual and material prejudice to it which cannot be reversed or otherwise eliminated without any material negative effect on the Company, and the omission to notify
      the Company will, in any event, not relieve the Company from any liability which it may have to indemnify Indemnitee otherwise than under this Agreement.  If, at the time of receipt of any such notice, the Company has director and officer insurance
      policies in effect, the Company will promptly notify the relevant insurers in accordance with the procedures and requirements of such policies.

    

    

    (b)

    Defense; Settlement.  Indemnitee shall have the sole right and obligation to control the defense or conduct of any claim or Proceeding with respect to Indemnitee.  The Company shall not,
      without the prior written consent of Indemnitee, which may be provided or withheld in Indemnitee’s sole discretion, effect any settlement of any Proceeding against Indemnitee or which could have been brought against Indemnitee or which potentially or
      actually imposes any cost, liability, exposure or burden on Indemnitee unless (i) such settlement solely involves the payment of money or performance of any obligation by persons other than Indemnitee and includes an unconditional release of
      Indemnitee by all relevant parties from all liability on any matters that are the subject of such Proceeding and an acknowledgment that Indemnitee denies all wrongdoing in connection with such matters and (ii) the Company has  fully indemnified the
      Indemnitee with respect to, and held Indemnitee harmless from and against, all Expenses actually and reasonably incurred by Indemnitee or on behalf of Indemnitee in connection with such Proceeding.  The Company shall not be obligated to indemnify
      Indemnitee against amounts paid in settlement of a Proceeding against Indemnitee if such settlement is effected by Indemnitee without the Company’s prior written consent, which consent shall not be unreasonably withheld, delayed or conditioned,
      unless such settlement solely involves the payment of money or performance of any obligation by persons other than the Company and includes an unconditional release of the Company by any party to such Proceeding other than the Indemnitee from all
      liability on any matters that are the subject of such Proceeding and an acknowledgment that the Company denies all wrongdoing in connection with such matters.

    

    

    
      4

      
        


    

    (c)

    Request for Advancement; Request for Indemnification.

    

    

    (i)

    To obtain advancement of Expenses under this Agreement, Indemnitee shall submit to the Company a written request therefor, together with such invoices or other supporting information as may be
      reasonably requested by the Company and reasonably available to Indemnitee, and, only to the extent required by applicable law which cannot be waived, an unsecured written undertaking to repay amounts advanced.  The Company shall make advance payment
      of Expenses to Indemnitee no later than ten (10) business days after receipt of the written request for advancement (and each subsequent request for advancement) by Indemnitee.  If, at the time of receipt of any such written request for advancement
      of Expenses, the Company has director and officer insurance policies in effect, the Company will promptly notify the relevant insurers in accordance with the procedures and requirements of such policies.  The Company shall thereafter keep such
      director and officer insurers informed of the status of the Proceeding or other claim and take such other actions, as appropriate to secure coverage of Indemnitee for such claim.

    

    

    (ii)

    To obtain indemnification under this Agreement, Indemnitee may submit a written request for indemnification hereunder.  The time at which Indemnitee submits a written request for indemnification
      shall be determined by the Indemnitee in the Indemnitee's sole discretion.  Once Indemnitee submits such a written request for indemnification (and only at such time that Indemnitee submits such a written request for indemnification), a Determination
      (as hereinafter defined) shall thereafter be made, as provided in and only to the extent required by Section 9(d) of this Agreement.  In no event shall a Determination be made, or required to be made, as a condition to or otherwise in
      connection with any advancement of Expenses pursuant to Section 8 and Section 9(c)(i) of this Agreement.  If, at the time of receipt of any such request for indemnification, the Company has director and officer insurance policies in
      effect, the Company will promptly notify the relevant insurers and take such other actions as necessary or appropriate to secure coverage of Indemnitee for such claim in accordance with the procedures and requirements of such policies.

    

    

    (d)

    Determination.  The Company agrees that Indemnitee shall be indemnified to the fullest extent permitted by law and that no Determination shall be required in connection with such
      indemnification unless specifically required by applicable law which cannot be waived.  In no event shall a Determination be required in connection with indemnification for Expenses pursuant to Section 7 of this Agreement or incurred in
      connection with any Proceeding or portion thereof with respect to which Indemnitee has been successful on the merits or otherwise.  Any decision that a Determination is required by law in connection with any other indemnification of Indemnitee, and
      any such Determination, shall be made within twenty (20) days after receipt of Indemnitee’s written request for indemnification pursuant to Section 9(c)(ii) and such Determination shall be made either (i) by the Disinterested Directors (as
      hereinafter defined), even though less than a quorum, so long as Indemnitee does not request that such Determination be made by Independent Counsel (as hereinafter defined), or (ii) if so requested by Indemnitee, in Indemnitee’s sole discretion, by
      Independent Counsel in a written opinion to the Company and Indemnitee.  If a Determination is made that Indemnitee is entitled to indemnification, payment to Indemnitee shall be made within ten (10) business days after such Determination. 
      Indemnitee shall reasonably 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 Expenses actually and reasonably incurred by Indemnitee
      in so cooperating with the Disinterested Directors or Independent Counsel, as the case may be, making such determination shall be advanced and borne by the Company (irrespective of the Determination as to Indemnitee’s entitlement to indemnification)
      and the Company is liable to indemnify and hold Indemnitee harmless therefrom.  If the person, persons or entity empowered or selected under Section 9(d) of this Agreement to determine whether Indemnitee is entitled to indemnification shall
      not have made a determination within twenty (20) days after receipt by the Company of the request therefor, the requisite determination of entitlement to indemnification shall, to the fullest extent not prohibited by law, 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 twenty (20) day period may be extended for a reasonable time, not to exceed an additional twenty (20) days, if the person, persons
      or entity making the determination with respect to entitlement to indemnification in good faith requires such additional time for the obtaining or evaluating of documentation and/or information relating thereto; and provided, further, that the
      foregoing provisions of this Section 9(d) shall not apply if the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 9(e).

    

    

    
      5

      
        


    

    (e)

    Independent Counsel.  In the event a Determination is to be made by Independent Counsel pursuant to Section 9(d) of this Agreement, the Independent Counsel shall be selected as
      provided in this Section 9(e).  The Independent Counsel shall be selected by Indemnitee (unless Indemnitee shall request that such selection be made by the Board of Directors, in which event the Board of Directors shall make such selection on
      behalf of the Company, subject to the remaining provisions of this Section 9(e)), and Indemnitee or the Company, as the case may be, shall give written notice to the other, advising the Company or Indemnitee of the identity of the Independent
      Counsel so selected.   The Company or Indemnitee, as the case may be, may, within ten (10) days after such written notice of selection shall have been received, deliver to Indemnitee or the Company, 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 15 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 such written objection is so made and substantiated, the
      Independent Counsel so selected may not serve as Independent Counsel unless and until such objection is withdrawn or a court of competent jurisdiction 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 9(c)(ii) of this Agreement and after a request for the appointment of Independent Counsel has been made, 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 Company or Indemnitee to the other’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 9(d) of this Agreement.  Upon the due commencement of any judicial proceeding or arbitration pursuant to Section 9(f) of this Agreement, Independent Counsel shall be discharged and relieved of any further responsibility
      in such capacity (subject to the applicable standards of professional conduct then prevailing).  Any expenses actually and reasonably incurred by or in connection with the appointment of Independent Counsel shall be borne by the Company (irrespective
      of the Determination of Indemnitee's entitlement to indemnification) and not by Indemnitee.

    

    

    (f)

    Consequences of Determination; Remedies of Indemnitee.  The Company shall be bound by and shall have no right to challenge a Favorable Determination.  If an Adverse Determination is made,
      or if for any other reason the Company does not make timely indemnification payments or advances of Expenses, Indemnitee shall have the right to commence a Proceeding before a court of competent jurisdiction to challenge such Adverse Determination
      and/or to require the Company to make such payments or advances (and the Company shall have the right to defend its position in such Proceeding and to appeal any adverse judgment in such Proceeding).  Indemnitee shall be entitled to be indemnified
      for all Expenses incurred in connection with such a Proceeding and to have such Expenses advanced by the Company in accordance with Section 8 of this Agreement.  If Indemnitee fails to challenge an Adverse Determination within fifteen (15)
      business days, or if Indemnitee challenges an Adverse Determination and such Adverse Determination has been upheld by a final judgment of a court of competent jurisdiction from which no appeal can be taken, then, to the extent and only to the extent
      required by such Adverse Determination or final judgment, the Company shall not be obligated to indemnify or advance Expenses to Indemnitee under this Agreement.

    

    

    (g)

    Presumptions; Burden and Standard of Proof.  The parties intend and agree that, to the extent permitted by law, in connection with any Determination with respect to Indemnitee’s entitlement
      to indemnification hereunder by any person, including a court:

    

    

    (i)

    it will be presumed that Indemnitee is entitled to indemnification under this Agreement (notwithstanding any Adverse Determination), and the Company or any other person or entity challenging such
      right will have the burden of proof to overcome that presumption in connection with the making by any person, persons or entity of any determination contrary to that presumption;

    

    

    (ii)

    the termination of any action, suit or 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 Company, and, with respect to any criminal action or proceeding,
      had reasonable cause to believe that Indemnitee’s conduct was unlawful;

    

    

    
      6

      
        


    

    (iii)

    For purposes of any determination of good faith, 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 Company, including
      financial statements, or on information supplied to Indemnitee by the officers, employees, or committees of the board of directors of the Company in the course of their duties, or on the advice of legal counsel or other advisors (including financial
      advisors and accountants) for the Company or on information or records given in reports made to the Company by an independent certified public accountant or by an appraiser or other expert or advisor selected by the Company; and

    

    

    (iv)

    the knowledge and/or actions, or failure to act, of any director, officer, agent or employee of the Company or relevant enterprises will not be imputed to Indemnitee in a manner that limits or
      otherwise adversely affects Indemnitee’s rights hereunder.

    

    

    The provisions of this Section 9(g) shall not be deemed to be exclusive or to limit in any way the other circumstances in which Indemnitee may be deemed to have met the applicable standard of conduct set forth in
      this Agreement.

    

    

    10.

    Remedies of Indemnitee.

    

    

    (a)

    Subject to Section 10(e), in the event that (i) a determination is made pursuant to Section 9(d) of this Agreement that Indemnitee is not entitled to indemnification under this
      Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 9(c) of this Agreement, (iii) no determination of entitlement to indemnification shall have been made pursuant to Section 9(d) of this Agreement within
      twenty (20) days after receipt by the Company of the request for indemnification, (iv) payment of indemnification is not made pursuant to Section 5, 6 or 7 of this Agreement within ten (10) business days after receipt by the
      Company of a written request therefor, (v) payment of indemnification pursuant to Section 3, 4 or 7 of this Agreement is not made within five (5) business days after a determination has been made that Indemnitee is entitled to
      indemnification, or (vi) in the event that the Company or any other person takes or threatens to take any action to declare this Agreement void or unenforceable, or institutes any litigation or other action or Proceeding designed to deny, or to
      recover from, the Indemnitee the benefits provided or intended to be provided to the Indemnitee hereunder, Indemnitee shall be entitled to an adjudication by a court of his entitlement to such indemnification or advancement of Expenses. 
      Alternatively, Indemnitee, at his option, may seek an award in arbitration to be conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association.  Indemnitee shall commence such proceeding seeking
      an adjudication or an award in arbitration within one hundred eighty (180) days following the date on which Indemnitee first has the right to commence such proceeding pursuant to this Section 10(a); provided, however, that the
      foregoing clause shall not apply in respect of a proceeding brought by Indemnitee to enforce his rights under Section 5 of this Agreement.  The Company shall not oppose Indemnitee’s right to seek any such adjudication or award in arbitration.

    

    

    (b)

    In the event that a determination shall have been made pursuant to Section 9(d) of this Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration
      commenced pursuant to this Section 10 shall be conducted in all respects as a de novo trial, or arbitration, on the merits, in which (i) Indemnitee shall not be prejudiced by reason of that adverse determination, and (ii) the Company shall
      bear the burden of establishing that Indemnitee is not entitled to indemnification.

    

    

    (c)

    If a determination shall have been made pursuant to Section 9(d) of this Agreement that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any
      judicial proceeding or arbitration commenced pursuant to this Section 10, 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.

    

    

    
      7

      
        


    

    (d)

    The Company shall, to the fullest extent not prohibited by law, be precluded from asserting in any judicial proceeding or arbitration commenced pursuant to this Section 10 that the
      procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator that the Company is bound by all the provisions of this Agreement.

    

    

    (e)

    Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement of Indemnitee to indemnification under this Agreement shall be required to be made prior to the final
      disposition of the Proceeding.

    

    

    11.

    Insurance; Subrogation; Other Rights of Recovery, etc.

    

    

    (a)

    The Company shall use its reasonable best efforts to purchase and maintain a policy or policies of insurance with reputable insurance companies with A.M. Best ratings of “A” or better, providing
      Indemnitee with coverage for any liability asserted against, and incurred by, Indemnitee or on Indemnitee’s behalf by reason of Indemnitee’s Corporate Status, or arising out of Indemnitee’s status as such, whether or not the Company would have the
      power to indemnify Indemnitee against such liability.  Such insurance policies shall have coverage terms and policy limits at least as favorable to Indemnitee as the insurance coverage provided to any other director or officer of the Company.  If the
      Company has such insurance in effect at the time it receives from Indemnitee any notice of the commencement of an action, suit, proceeding or other claim, the Company shall give prompt notice of the commencement of such action, suit, proceeding or
      other claim to the insurers and take such other actions in accordance with the procedures set forth in the policy as required or appropriate to secure coverage of Indemnitee for such action, suit, proceeding or other claim.  The Company shall
      thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of Indemnitee, all amounts payable as a result of such action, suit, proceeding or other claim in accordance with the terms of such policy.  The Company shall
      continue to provide such insurance coverage to Indemnitee for a period of at least ten (10) years after Indemnitee ceases to serve as a director or an officer or in any other Corporate Status.

    

    

    (b)

    The Company shall not be liable to pay or advance to Indemnitee any amounts otherwise indemnifiable under this Agreement or under any other indemnification agreement if and to the extent that
      Indemnitee has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise; provided, however, that (i) the Company hereby agrees that it is the indemnitor of first resort under this Agreement and under any
      other indemnification agreement (i.e., its obligations to Indemnitee under this Agreement or any other agreement or undertaking to provide advancement and/or indemnification to Indemnitee are primary and any obligation of any other entity to provide
      advancement or indemnification, or any obligation of any insurer of any other entity to provide insurance coverage, for the same Expenses, liabilities, judgments, penalties, fines and amounts paid in settlement (including all interest, assessments
      and other charges paid or payable in connection with or in respect of such Expenses, liabilities, judgments, penalties, fines and amounts paid in settlement) incurred by Indemnitee are secondary), and (ii) if any other entity pays or causes to be
      paid, for any reason, any amounts otherwise indemnifiable hereunder or under any other indemnification agreement (whether pursuant to contract, bylaws or charter) with Indemnitee in connection with Indemnitee’s service to the Company, then (x) such
      other entity shall be fully subrogated to all rights of Indemnitee with respect to such payment and (y) the Company shall fully indemnify, reimburse and hold harmless such other entity for all such payments actually made by such other entity.

    

    

    (c)

    Except as provided in Section 11(b) of this Agreement, the rights to indemnification and advancement of Expenses as provided by this Agreement shall not be deemed exclusive of any other
      rights to which Indemnitee may at any time, whenever conferred or arising, be entitled under applicable law, under the Certificate of Incorporation or Bylaws, or under any other agreement, or otherwise.  Indemnitee’s rights under this Agreement are
      present contractual rights that fully vest upon Indemnitee’s first service as a director or an officer of the Company.  The Parties hereby agree that Section 11(b) of this Agreement shall be deemed exclusive and shall be deemed to modify,
      amend and clarify any right to indemnification or advancement provided to Indemnitee under any other contract, agreement or document with the Company.

    (d)

    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 Indemnitee’s Corporate Status prior to such amendment, alteration or repeal.  To the extent that a change in the General Corporation Law of the State of Delaware (or other applicable law), whether by statute or judicial decision,
      permits greater indemnification or advancement of Expenses than would be afforded currently under the Certificate of Incorporation or Bylaws and this Agreement, it is the intent of the parties hereto that Indemnitee enjoy by this Agreement the
      greater benefits so afforded by such change.  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)

    

    This Agreement shall be binding upon the Company and its successors and assigns and shall inure to the benefit of Indemnitee and Indemnitee’s heirs, executors and administrators.  If the Company or
      any of its successors or assigns shall (i) consolidate with or merge into any other corporation or entity and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfer all or substantially all of
      its properties and assets to any individual, corporation or other entity, then, and in each such case, proper provisions shall be made so that the successors and assigns of the Company shall assume all of the obligations set forth in this Agreement.

      invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested thereby.
