Exhibit 10.6


 


FORM OF INDEMNITY AGREEMENT


 


THIS INDEMNITY AGREEMENT
(this “Agreement”) is made as of _____________, 2020, by and between Yellowstone Acquisition Company, a
Delaware corporation (the “Company”), and ___________________ (“Indemnitee”).


 


RECITALS


 


WHEREAS, highly
competent persons have become more reluctant to serve publicly-held corporations as directors, officers or in other capacities
unless they are provided with adequate protection through insurance or adequate indemnification against inordinate risks of claims
and actions against them arising out of their service to and activities on behalf of such corporations;


 


WHEREAS, the
Board of Directors of the Company (the “Board”) has determined that, in order to attract and retain qualified
individuals, the Company will attempt to maintain on an ongoing basis, at its sole expense, liability insurance to protect persons
serving the Company and its subsidiaries from certain liabilities. Although the furnishing of such insurance has been a customary
and widespread practice among United States-based corporations and other business enterprises, the Company believes that, given
current market conditions and trends, such insurance may be available to it in the future only at higher premiums and with more
exclusions. At the same time, directors, officers and other persons in service to corporations or business enterprises are being
increasingly subjected to expensive and time-consuming litigation relating to, among other things, matters that traditionally would
have been brought only against the Company or business enterprise itself. The Amended and Restated Certificate of Incorporation
(the “Charter”) and the Bylaws (the “Bylaws”) of the Company require indemnification of the
officers and directors of the Company. Indemnitee may also be entitled to indemnification pursuant to applicable provisions of
the Delaware General Corporation Law (“DGCL”). The Charter, Bylaws and the DGCL expressly provide that the indemnification
provisions set forth therein are not exclusive, and thereby contemplate that contracts may be entered into between the Company
and members of the Board, officers and other persons with respect to indemnification, hold harmless, exoneration, advancement and
reimbursement rights;


 


WHEREAS, the
uncertainties relating to such insurance and to indemnification have increased the difficulty of attracting and retaining such
persons;


 


WHEREAS, the
Board has determined that the increased difficulty in attracting and retaining such persons is detrimental to the best interests
of the Company’s stockholders and that the Company should act to assure such persons that there will be increased certainty
of such protection in the future;


 


WHEREAS, it
is reasonable, prudent and necessary for the Company contractually to obligate itself to indemnify, hold harmless, exonerate and
to advance expenses on behalf of, such persons to the fullest extent permitted by applicable law so that they will serve or continue
to serve the Company free from undue concern that they will not be so protected against liabilities;


 






     


     


    




 


WHEREAS, this
Agreement is a supplement to and in furtherance of the Charter and Bylaws 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;


 


WHEREAS, Indemnitee
may not be willing to serve as an officer or director, advisor or in another capacity without adequate protection, and the Company
desires Indemnitee to serve in such capacity. Indemnitee is willing to serve, continue to serve and to take on additional service
for or on behalf of the Company on the condition that Indemnitee be so indemnified; and


 


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

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, as provided in Article XVII. This Agreement, however, shall
not impose any obligation on Indemnitee or the Company to continue Indemnitee’s service to the Company beyond any period

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.

WHO
IS WHOLLY OR PARTLY SUCCESSFUL


 


Notwithstanding any
other provisions of this Agreement except for Article XXVII, to the extent that Indemnitee was or is, by reason
of Indemnitee’s Corporate Status, a party to (or a participant in) and is successful, on the merits or otherwise, in any
Proceeding or in defense of any claim, issue or matter therein, in whole or in part, the Company shall, to the fullest extent permitted
by applicable law, indemnify, hold harmless and exonerate Indemnitee against all Expenses actually and reasonably incurred by Indemnitee
in connection therewith. If Indemnitee is not wholly successful in such Proceeding but is successful, on the merits or otherwise,

assessments and other charges paid or payable in connection with or in respect of such Expenses, judgments, fines, penalties and
amounts paid in settlement) actually and reasonably incurred by Indemnitee in connection with the Proceeding. No indemnification,

or exonerating Indemnitee, shall pay, in the first instance, the entire amount incurred by Indemnitee, whether for judgments, liabilities,
fines, penalties, amounts paid or to be paid in settlement and/or for Expenses, in connection with any Proceeding without requiring
Indemnitee to contribute to such payment, and the Company hereby waives and relinquishes any right of contribution it may have
at any time against Indemnitee.

agrees to fully indemnify, hold harmless and exonerate Indemnitee from any claims for contribution which may be brought by officers,
directors or employees of the Company other than Indemnitee who may be jointly liable with Indemnitee.

EXCLUSIONS


 


Notwithstanding any
provision in this Agreement, the Company shall not be obligated under this Agreement to make any indemnification, advance expenses,
hold harmless or exoneration payment in connection with any claim made against Indemnitee:

has actually been received by or on behalf of Indemnitee under any insurance policy or other indemnity or advancement provision,
except with respect to any excess beyond the amount actually received under any insurance policy, contract, agreement, other indemnity
or advancement provision or otherwise;


 


(b) for an accounting
of profits made from the purchase and sale (or sale and purchase) by Indemnitee of securities of the Company within the meaning

hold harmless or exoneration payment, in its sole discretion, pursuant to the powers vested in the Company under applicable law.
Indemnitee shall seek payments or advances from the Company only to the extent that such payments or advances are unavailable from

ARTICLE
X.

ADVANCES OF EXPENSES; DEFENSE OF CLAIM


 


(a) Notwithstanding
any provision of this Agreement to the contrary, except for Article XXVII, and to the fullest extent not prohibited
by applicable law, the Company shall pay the Expenses incurred by Indemnitee (or reasonably expected by Indemnitee to be incurred
by Indemnitee within three months) in connection with any Proceeding within ten (10) days after the receipt by the Company of a
statement or statements requesting such advances from time to time, prior to the final disposition of any Proceeding. Advances
shall, to the fullest extent permitted by law, be unsecured and interest free. Advances shall, to the fullest extent permitted
by law, be made without regard to Indemnitee’s ability to repay the Expenses and without regard to Indemnitee’s ultimate
entitlement to be indemnified, held harmless or exonerated under the other provisions of this Agreement. Advances shall include
any and all reasonable Expenses incurred pursuing a Proceeding to enforce this right of advancement, including Expenses incurred
preparing and forwarding statements to the Company to support the advances claimed. To the fullest extent required by applicable
law, such payments of Expenses in advance of the final disposition of the Proceeding shall be made only upon the Company’s
receipt of an undertaking, by or on behalf of Indemnitee, to repay the advanced amounts to the extent that it is ultimately determined
that Indemnitee is not entitled to be indemnified, held harmless or exonerated by the Company under the provisions of this Agreement,
the Charter, the Bylaws of the Company, applicable law or otherwise. This Article X(a) shall not apply to any
claim made by Indemnitee for which an indemnification, hold harmless or exoneration payment is excluded pursuant to Article IX.


 






    8


     


    




 


(b) The Company will
be entitled to participate in the Proceeding at its own expense.


 


(c) The Company shall
not settle any action, claim or Proceeding (in whole or in part) which would impose any Expense, judgment, fine, penalty or limitation
on Indemnitee without Indemnitee’s prior written consent.


 


ARTICLE
XI.

PROCEDURE FOR NOTIFICATION AND APPLICATION FOR INDEMNIFICATION


 


(a) Indemnitee agrees
to notify promptly the Company in writing upon being served with any summons, citation, subpoena, complaint, indictment, information
or other document relating to any Proceeding, claim, issue or matter therein which may be subject to indemnification, hold harmless
or exoneration rights, or advancement of Expenses covered hereunder. The failure of Indemnitee to so notify the Company shall not
relieve the Company of any obligation which it may have to Indemnitee under this Agreement, or otherwise.


 


(b) Indemnitee may
deliver to the Company a written application to indemnify, hold harmless or exonerate Indemnitee in accordance with this Agreement.
Such application(s) may be delivered from time to time and at such time(s) as Indemnitee deems appropriate in his or her sole discretion.
Following such a written application for indemnification by Indemnitee, Indemnitee’s entitlement to indemnification shall
be determined according to Article XII(a) of this Agreement.


 


ARTICLE
XII.

PROCEDURE UPON APPLICATION FOR INDEMNIFICATION


 


(a) A determination,
if required by applicable law, with respect to Indemnitee’s entitlement to indemnification shall be made in the specific
case by one of the following methods, which shall be at the election of Indemnitee: (i) by a majority vote of the Disinterested
Directors, even though less than a quorum of the Board, (ii) by a committee of such directors designated by majority vote
of such directors, (iii) if there are no Disinterested Directors or if such directors so direct, by Independent Counsel in
a written opinion to the Board, a copy of which shall be delivered to Indemnitee or (iv) by vote of the stockholders. The
Company promptly will advise Indemnitee in writing with respect to any determination that Indemnitee is or is not entitled to indemnification,
including a description of any reason or basis for which indemnification has been denied. If it is so determined that Indemnitee
is entitled to indemnification, payment to Indemnitee shall be made within ten (10) 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 costs or Expenses (including reasonable 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 agrees to indemnify
and to hold Indemnitee harmless therefrom.


 






    9


     


    




 


(b) In the event
the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Article XII(a) hereof,
the Independent Counsel shall be selected as provided in this Article XII(b). The Independent Counsel shall be selected
by Indemnitee (unless Indemnitee shall request that such selection be made by the Board), and Indemnitee shall give written notice
to the Company advising it of the identity of the Independent Counsel so selected and certifying that the Independent Counsel so
selected meets the requirements of “Independent Counsel” as defined in Article II of this Agreement.
If the Independent Counsel is selected by the Board, the Company shall give written notice to Indemnitee advising Indemnitee of
the identity of the Independent Counsel so selected and certifying that the Independent Counsel so selected meets the requirements
of “Independent Counsel” as defined in Article II of this Agreement. In either event, Indemnitee
or the Company, as the case may be, may, within ten (10) days after such written notice of selection shall have been received,
deliver to the Company or to Indemnitee, 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 Article II 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 Article
XI(b) hereof, no Independent Counsel shall have been selected and not objected to, either the Company or Indemnitee may
petition the Delaware Court 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 Delaware Court,
and the person with respect to whom all objections are so resolved or the person so appointed shall act as Independent Counsel
under Article XII(a) hereof. Upon the due commencement of any judicial proceeding or arbitration pursuant to Article
XII(a) 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).


 


(c) The Company agrees
to pay the reasonable fees and expenses of Independent Counsel and to fully indemnify and hold harmless such Independent Counsel
against any and all Expenses, claims, liabilities and damages arising out of or relating to this Agreement or its engagement pursuant
hereto.


 


ARTICLE
XIII.

PRESUMPTIONS AND EFFECT OF CERTAIN PROCEEDINGS


 


(a) In making a determination
with respect to entitlement to indemnification hereunder, the person, persons or entity making such determination shall presume
that Indemnitee is entitled to indemnification under this Agreement if Indemnitee has submitted a request for indemnification in
accordance with Article XI(b) of this Agreement, and the Company shall 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. Neither
the failure of the Company (including by the Disinterested Directors or Independent Counsel) to have made a determination prior
to the commencement of any action pursuant to this Agreement that indemnification is proper in the circumstances because Indemnitee
has met the applicable standard of conduct, nor an actual determination by the Company (including by the Disinterested Directors
or Independent 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.


 






    10


     


    




 


(b) If the person,
persons or entity empowered or selected under Article XII of this Agreement to determine whether Indemnitee
is entitled to indemnification shall not have made a determination within thirty (30) days after receipt by the Company of the
request therefor, the requisite determination of entitlement to indemnification shall, to the fullest extent permitted 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 final judicial determination that any or all such indemnification
is expressly prohibited under applicable law; provided, however, that such thirty (30)-day period may be extended for a reasonable
time, not to exceed an additional fifteen (15) 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.


 


(c) 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
Indemnitee 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 Indemnitee’s conduct was unlawful.


 


(d) For purposes
of any determination of good faith, 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, including financial statements, or on information supplied to Indemnitee
by the directors, managers or officers of the Enterprise in the course of their duties, or on the advice of legal counsel for the
Enterprise, its Board, any committee of the Board or any director, trustee, general partner, manager or managing member, or on
information or records given or reports made to the Enterprise, its Board, any committee of the Board or any director, trustee,
general partner, manager or managing member, by an independent certified public accountant or by an appraiser or other expert selected
by the Enterprise, its Board, any committee of the Board or any director, trustee, general partner, manager or managing member.
The provisions of this Article XIII(d) shall not be deemed to be exclusive or to limit in any way the other circumstances
in which Indemnitee may be deemed or found to have met the applicable standard of conduct set forth in this Agreement.

(e) The knowledge
and/or actions, or failure to act, of any other director, officer, trustee, partner, manager, managing member, fiduciary, agent
or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under
this Agreement.


 


ARTICLE
XIV.

REMEDIES OF INDEMNITEE


 


(a) In the event
that (i) a determination is made pursuant to Article XII of this Agreement that Indemnitee is not entitled
to indemnification under this Agreement, (ii) advancement of Expenses, to the fullest extent permitted by applicable law,
is not timely made pursuant to Article X of this Agreement, (iii) no determination of entitlement to indemnification
shall have been made pursuant to Article XII(a) of this Agreement within thirty (30) days after receipt by the
Company of the request for indemnification, (iv) payment of indemnification is not made pursuant to Articles V, VI, VII or
the last sentence of Article XII(a) of this Agreement within ten (10) days after receipt by the Company of a written
request therefor, (v) a contribution payment is not made in a timely manner pursuant to Article VIII of
this Agreement, (vi) payment of indemnification pursuant to Article III or IV of this
Agreement is not made within ten (10) days after a determination has been made that Indemnitee is entitled to indemnification or
(vii) payment to Indemnitee pursuant to any hold harmless or exoneration rights under this Agreement or otherwise is not made
in accordance with this Agreement, Indemnitee shall be entitled to an adjudication by the Delaware Court to such indemnification,
hold harmless, exoneration, contribution or advancement rights. Alternatively, Indemnitee, at Indemnitee’s 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. Except as set forth herein, the provisions of Delaware law (without regard to its conflict of laws rules) shall apply
to any such arbitration. 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 Article XII(a) of this Agreement that Indemnitee is not
entitled to indemnification, any judicial proceeding or arbitration commenced pursuant to this Article XIV shall
be conducted in all respects as a de novo trial, or arbitration, on the merits and Indemnitee shall not be prejudiced by reason
of that adverse determination.


 


(c) In any judicial
proceeding or arbitration commenced pursuant to this Article XIV, Indemnitee shall be presumed to be entitled
to be indemnified, held harmless, exonerated and to receive advancement of Expenses under this Agreement and the Company shall
have the burden of proving Indemnitee is not entitled to be indemnified, held harmless, exonerated and to receive advancement of
Expenses, as the case may be, and the Company may not refer to or introduce into evidence any determination pursuant to Article
XII(a) of this Agreement adverse to Indemnitee for any purpose. If Indemnitee commences a judicial proceeding or arbitration
pursuant to this Article XIV, Indemnitee shall not be required to reimburse the Company for any advances pursuant
to Article X until a final determination is made with respect to Indemnitee’s entitlement to indemnification
(as to which all rights of appeal have been exhausted or lapsed).


 






    12


     


    




 


(d) If a determination
shall have been made pursuant to Article XII(a) 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 Article XIV,
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.


 


(e) The Company shall
be precluded from asserting in any judicial proceeding or arbitration commenced pursuant to this Article XIV 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.


 


(f) The Company shall
indemnify and hold harmless Indemnitee to the fullest extent permitted by law against all Expenses and, if requested by Indemnitee,
shall (within ten (10) days after the Company’s receipt of such written request) pay to Indemnitee, to the fullest extent
permitted by applicable law, such Expenses which are incurred by Indemnitee in connection with any judicial proceeding or arbitration
brought by Indemnitee: (i) to enforce his or her rights under, or to recover damages for breach of, this Agreement or any
other indemnification, hold harmless, exoneration, advancement or contribution agreement or provision of the Charter or the Bylaws
now or hereafter in effect; or (ii) for recovery or advances under any insurance policy maintained by any person for the benefit
of Indemnitee, regardless of the outcome and whether Indemnitee ultimately is determined to be entitled to such indemnification,
hold harmless or exoneration right, advancement, contribution or insurance recovery, as the case may be (unless such judicial proceeding
or arbitration was not brought by Indemnitee in good faith).


 


(g) Interest shall
be paid by the Company to Indemnitee at the legal rate under Delaware law for amounts which the Company indemnifies, holds harmless
or exonerates, or advances, or is obliged to indemnify, hold harmless or exonerate or advance for the period commencing with the
date on which Indemnitee requests indemnification, to be held harmless, exonerated, contribution, reimbursement or advancement
of any Expenses and ending with the date on which such payment is made to Indemnitee by the Company.


 


ARTICLE
XV.

SECURITY


 


Notwithstanding anything
herein to the contrary, except for Article XXVII, 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 Indemnitee.

ARTICLE
XVI.

NON-EXCLUSIVITY; SURVIVAL OF RIGHTS; INSURANCE; SUBROGATION


 


(a) The rights of
Indemnitee 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 Charter, the Bylaws, any agreement, a vote of stockholders or a resolution of directors,
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 Proceeding (regardless of when such Proceeding is first threatened, commenced
or completed) or claim, issue or matter therein arising out of, or related to, 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 applicable law,
whether by statute or judicial decision, permits greater indemnification, hold harmless or exoneration rights or advancement of
Expenses than would be afforded currently under the Charter, the Bylaws or 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) The DGCL, the
Charter and the Bylaws permit the Company to purchase and maintain insurance or furnish similar protection or make other arrangements
including, but not limited to, providing a trust fund, letter of credit or surety bond (“Indemnification Arrangements”)
on behalf of Indemnitee against any liability asserted against Indemnitee or incurred by or on behalf of Indemnitee or in such
capacity as a director, officer, employee or agent of the Company, or arising out of Indemnitee’s status as such, whether
or not the Company would have the power to indemnify Indemnitee against such liability under the provisions of this Agreement or
under the DGCL, as it may then be in effect. The purchase, establishment, and maintenance of any such Indemnification Arrangement
shall not in any way limit or affect the rights and obligations of the Company or of Indemnitee under this Agreement except as
expressly provided herein, and the execution and delivery of this Agreement by the Company and Indemnitee shall not in any way
limit or affect the rights and obligations of the Company or the other party or parties thereto under any such Indemnification
Arrangement.


 


(c) To the extent
that the Company maintains an insurance policy or policies providing liability insurance for directors, officers, trustees, partners,
managers, managing members, fiduciaries, employees or agents of the Company or of any other Enterprise which such person serves
at the request of the Company, 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 such director, officer, trustee, partner, managers, managing member, fiduciary,
employee or agent under such policy or policies. If, at the time the Company receives notice from any source of a Proceeding as
to which Indemnitee is a party or a participant (as a witness, deponent or otherwise), the Company has director and officer liability
insurance in effect, the Company shall give prompt notice 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 Indemnitee, all amounts payable as a result of such Proceeding in accordance with the terms of such policies.


 






    14


     


    




 


(d) In the event
of any payment under this Agreement, the Company, to the fullest extent permitted by law, shall be subrogated to the extent of
such payment to all of the rights of recovery of Indemnitee, 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) The Company’s
obligation to indemnify, hold harmless, exonerate or advance Expenses hereunder to Indemnitee who is or was serving at the request
of the Company as a director, officer, trustee, partner, manager, managing member, fiduciary, employee or agent of any other Enterprise
shall be reduced by any amount Indemnitee has actually received as indemnification, hold harmless or exoneration payments or advancement
of expenses from such Enterprise. Notwithstanding any other provision of this Agreement to the contrary except for Article XXVII,
(i) Indemnitee shall have no obligation to reduce, offset, allocate, pursue or apportion any indemnification, hold harmless,
exoneration, advancement, contribution or insurance coverage among multiple parties possessing such duties to Indemnitee prior
to the Company’s satisfaction and performance of all its obligations under this Agreement, and (ii) the Company shall
perform fully its obligations under this Agreement without regard to whether Indemnitee holds, may pursue or has pursued any indemnification,
advancement, hold harmless, exoneration, contribution or insurance coverage rights against any person or entity other than the
Company.


 


ARTICLE
XVII.

DURATION OF AGREEMENT


 


All agreements and
obligations of the Company contained herein shall continue during the period Indemnitee serves as a director or officer of the
Company or as a director, officer, trustee, partner, manager, managing member, fiduciary, employee or agent of any other corporation,
partnership, joint venture, trust, employee benefit plan or other Enterprise which Indemnitee serves at the request of the Company
and shall continue thereafter so long as Indemnitee shall be subject to any possible Proceeding (including any rights of appeal
thereto and any Proceeding commenced by Indemnitee pursuant to Article XIV of this Agreement) by reason of
Indemnitee’s Corporate Status, whether or not Indemnitee is acting in any such capacity at the time any liability or expense
is incurred for which indemnification or advancement can be provided under this Agreement.


 


ARTICLE
XVIII.

SEVERABILITY


 


If any provision
or provisions of this Agreement shall be held to be invalid, illegal or unenforceable for any reason whatsoever: (a) the validity,
legality and enforceability of the remaining provisions of this Agreement (including, without limitation, each portion of any Article,
paragraph or sentence of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not
itself invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and shall remain enforceable to
the fullest extent permitted by law; (b) such provision or provisions shall be deemed reformed to the extent necessary to
conform to applicable law and to give the maximum effect to the intent of the parties hereto; and (c) to the fullest extent
possible, the provisions of this Agreement (including, without limitation, each portion of any Article, paragraph or sentence of
this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal
or unenforceable) shall be construed so as to give effect to the intent manifested thereby.

ARTICLE
XIX.

ENFORCEMENT AND BINDING EFFECT


 


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


 


(b) Without limiting
any of the rights of Indemnitee under the Charter or Bylaws of the Company as they may be amended from time to time, this Agreement
constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes all prior
agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof.


 


(c) The indemnification,
hold harmless, exoneration and advancement of expenses rights provided by or granted pursuant to this Agreement shall be binding
upon and be enforceable by the parties hereto and their respective successors and assigns (including any direct or indirect successor
by purchase, merger, consolidation or otherwise to all or substantially all of the business and/or assets of the Company), shall
continue as to an Indemnitee who has ceased to be a director, officer, employee or agent of the Company or a director, officer,
trustee, general partner, manager, managing member, fiduciary, employee or agent of any other Enterprise at the Company’s
request, and shall inure to the benefit of Indemnitee and Indemnitee’s spouse, assigns, heirs, devisees, executors and administrators
and other legal representatives.


 


(d) The Company shall
require and cause any successor (whether direct or indirect by purchase, merger, consolidation or otherwise) to all, substantially
all or a substantial part, of the business and/or assets of the Company, by written agreement in form and substance satisfactory
to Indemnitee, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Company
would be required to perform if no such succession had taken place.


 


(e) The Company and
Indemnitee agree herein that a monetary remedy for breach of this Agreement, at some later date, may be inadequate, impracticable
and difficult to prove, and further agree that such breach may cause Indemnitee irreparable harm. Accordingly, the parties hereto
agree that Indemnitee may, to the fullest extent permitted by law, enforce this Agreement by seeking, among other things, injunctive
relief and/or specific performance hereof, without any necessity of showing actual damage or irreparable harm and that by seeking
injunctive relief and/or specific performance, Indemnitee shall not be precluded from seeking or obtaining any other relief
to which Indemnitee may be entitled. The Company and Indemnitee further agree that Indemnitee shall, to the fullest extent permitted
by law, be entitled to such specific performance and injunctive relief, including temporary restraining orders, preliminary injunctions
and permanent injunctions, without the necessity of posting bonds or other undertaking in connection therewith. The Company acknowledges
that in the absence of a waiver, a bond or undertaking may be required of Indemnitee by a court of competent jurisdiction. The
Company hereby waives any such requirement of such a bond or undertaking to the fullest extent permitted by law.
