the terms, agreements, or covenants, contained herein or in any of the other Loan Documents (as such term is defined in the Loan Commitment Agreement) to which Maker is a party; 
 4. Maker or ADA shall become insolvent or shall apply for, shall consent to, or shall acquiesce in the appointment of a custodian, trustee
or receiver thereof or for a substantial part of the property thereof, or, in the absence of such application, consent or acquiescence, a custodian, trustee or receiver shall be appointed for such party or for a substantial part of its property, or
such party shall make an assignment for the benefit of its creditors generally; 
 5. Maker or ADA shall be voluntarily or

or Maker, as applicable, is a party in which in

  

 -2- 








 
excess of 50% of ADA’s or Maker’s, as applicable, voting power is transferred (including, without limitation, in connection with any bankruptcy or similar proceeding), excluding any
consolidation or merger effected exclusively to change the domicile of ADA or Maker, as applicable, or (ii) sale, lease, license or other disposition of all or substantially all of the assets of ADA or Maker, as applicable;

Pledge Agreement, a valid and perfected first priority security interest in the Pledged Shares (as such term is defined in the Pledge Agreement) upon issuance and delivery thereof; or 
 9. if Maker or any endorser or guarantor of its respective obligations under the loan evidenced hereby (i) purports to disavow its
obligations under the loan evidenced hereby or under the other Loan Documents (as such term is defined in the Loan Commitment Agreement), (ii) declares that it does not have any further obligation in connection with the loan evidenced hereby,
or (iii) contests the validity or enforceability of the Loan Documents. 
 Upon the occurrence of any Event Of Default, the
Payee may (but is not obligated to) take any one or more of the following actions, without request or any further action on the part of Payee, in any order or combination and without being subject to waiver or latches at any time:
(i) accelerate the maturity of this Note and declare this Note and all amounts payable hereunder to be immediately due and payable in full, or (ii) exercise any other right or remedy provided under the UCC (as such term is defined in the
Pledge Agreement), in equity, at law or under any of the Loan Documents. Any failure of Payee to exercise any such rights or remedies, from time to time, shall not constitute a waiver of the right to exercise any such rights or remedies at any other
time. 
 Following the occurrence and during the continuance of an Event Of Default, the Interest Rate applicable to all unpaid
principal and interest due and payable hereunder shall be increased to fifteen percent (15%) per annum until paid. 
 It is
not intended hereby to charge interest at a rate in excess of the maximum rate of interest permitted to be charged to Maker under applicable law, but if, notwithstanding such intention, interest in excess of the maximum rate shall be paid hereunder,
the excess shall be retained by Payee as additional cash collateral for the payment of this Note, unless such retention is not permitted by law, in which case the interest rate on this Note shall be adjusted to the maximum rate permitted under
applicable law during the period or periods that the interest rate otherwise provided herein would exceed such rate.

 No renewal or extension granted, or any indulgence shown to, or any release of, or any
dealings between Payee and Maker and any other person now or hereafter interested in this Note or in the property securing this Note, whether as owner, encumbrancer, grantor, guarantor, or otherwise, shall discharge or in any way affect the
obligations of Maker hereunder. 
 In connection with the issuance of this Note, Maker hereby represents and warrants to Payee,
as of the date hereof, that the execution and delivery of this Note by Maker does not violate, conflict with or otherwise result in the breach of any agreement or understanding, whether written or oral, to which Maker is a party and no consent,
notice or waiver is required by or on behalf of Maker to any third party in order to issue and agree to be bound by the terms hereof. This Note constitutes the legal, valid and binding obligation of Maker, enforceable against Maker in accordance
with the terms hereof, except as enforcement may be limited by bankruptcy, insolvency, or similar laws affecting the enforcement of creditors’ rights generally and by general principles of equity. 
 Maker and any endorser or guarantor of this Note severally waive presentment, demand, notice of dishonor, notice of non-payment, presentment
for payment, notice of acceleration and protest and assent to any extension of time with respect to any payment due under this Note, to any substitution or release of collateral and to the addition or release of any party. No waiver of any payment
or other right under this Note shall operate as a waiver of any other payment or right. If this Note is not paid when due or declared due hereunder, Maker and any endorser or guarantor of this Note will jointly and severally pay all reasonable costs
of collection of this Note and any guaranty hereof (including, without limitation, reasonable attorneys’ fees and expenses), whether suit is brought, and reasonable costs of realizing upon any collateral at any time securing this Note
(including, without limitation, reasonable attorneys’ fees and expenses); provided, that ADA, in its capacity as a guarantor of this Note, shall only be responsible for paying fifty percent (50%) of any such reasonable costs of collection
of this Note, unless Payee seeks enforcement of the Guaranty, in which case ADA shall be responsible for all of the reasonable costs of collection thereunder. If any suit, claim or proceeding is brought in connection with this Note, the prevailing
party shall be entitled to be reimbursed by the non-prevailing party for all of the prevailing party’s associated fees and expenses. 
 This Note may not be changed orally, but only by an agreement in writing, signed by the party against whom enforcement of any waiver, change, modification or discharge is sought. If any of the provisions
of this Note shall be held to be invalid or unenforceable, the determination of invalidity or unenforceability of any such provision shall not affect the validity or enforceability of any other provision or provisions hereof. This Note shall be
binding upon Maker and its successors and assigns and shall inure to the benefit of and be enforceable by the Payee (or any subsequent holder hereof) and its successors and assigns. 
 THIS NOTE IS GOVERNED BY, AND WILL BE CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF COLORADO, WITHOUT REGARD TO ANY CONFLICTS OF
LAW RULES. THE MAKER, EACH ENDORSER OR GUARANTOR OF THIS NOTE, THE PAYEE, AND EACH HOLDER OF THIS NOTE SEVERALLY WAIVES ALL RIGHTS TO HAVE ANY MATTER PERTAINING TO THIS NOTE OR THE LOAN EVIDENCED BY THIS NOTE, AND ANY COLLATERAL SECURING THIS NOTE
TRIED BY A JURY.
