Bankruptcy Law that:

declare, by sending written notice to the Company, the principal of, premium, if any, and accrued and unpaid interest, if any, on all the Notes to be due and payable. Upon sending such a notice of acceleration, such principal, premium and accrued
and unpaid interest shall be due and payable immediately. In the event of the acceleration of the Notes because an Event of Default described in Section 7(a)(v) has occurred and is continuing, the acceleration of the Indebtedness
evidenced by the Non-Convertible Notes shall be automatically annulled if the Event of Default or payment default triggering such Event of Default pursuant to Section 7(a)(v) shall be remedied or cured by the Company or a Subsidiary of
the Company or waived by the Majority Noteholders of the Non-Convertible Notes within 20 days after the declaration of acceleration with respect thereto and if (1) the annulment of the acceleration of the Non-Convertible Notes would not
conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default, except nonpayment of principal, premium or interest on the Non-Convertible Notes that became due solely because of the

Make-Whole Price in respect of the aggregate outstanding principal amount of all Non-Convertible Notes, calculated as of the day immediately preceding the date of such Event of Default, plus (B) accrued and unpaid interest with respect to all
Non-Convertible Notes to the day immediately preceding the date of such Event of Default, shall automatically become and be immediately due and payable by the Company to the Holders of the Non-Convertible Notes without any declaration or other act
on the part of any Holders. The Majority Noteholders of the Non-Convertible Notes may rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree of a court of competent jurisdiction. No such
rescission shall affect any subsequent Default or impair any right consequent thereto. 
 c. The Majority Noteholders of the
Non-Convertible Notes may, by written notice signed thereby to the Company, waive an existing Default and its consequences to the extent provided in Section 8.3 of the Purchase Agreement. When a Default is waived, it is deemed cured, but no
such waiver shall extend to any subsequent or other Default or impair any consequent right. 
 d. Any Holder of
Non-Convertible Notes may exercise any remedy or conduct any proceeding available to Holders at the time and in the manner directed by the Majority Noteholders of the Non-Convertible Notes. Except to enforce the right to receive payment of
principal, premium (if any) or interest when due, no Holder of Notes may pursue any remedy with respect to the Purchase Agreement or the Notes unless the Majority Noteholders of the Non-Convertible Notes have requested such Holder of Notes to pursue
the remedy, such request to be evidenced by a certificate of an officer of such Holder, certifying that such Majority Noteholders have requested pursuit of such remedies, and delivered to the Company.

bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. 

8. Absence of Stockholder Approval. At any time after a Stockholder Meeting at which Stockholder Approval has not been obtained,
Holders of at least 25% in principal amount of all of the outstanding Non-Convertible Notes may, by prior written notice (signed by such Holders) to the Company, declare, by sending written notice to the Company, the principal of, premium, if any,
and accrued and unpaid interest, if any, on all the Non-Convertible Notes to be due and payable. Such principal, premium and accrued and unpaid interest shall be due and payable on the day that is 60 days following the date on such notice is
delivered to the Company. The Majority Noteholders of the Non-Convertible Notes may rescind such acceleration and its consequences if the rescission would not conflict with any judgment or decree of a court of competent jurisdiction. No such
rescission shall affect any subsequent Default or impair any right consequent thereto. 
 9. Usury Savings Clause. It is the intent
of the parties to the Purchase Agreement in the execution and performance thereof and hereof to remain in strict compliance with Applicable Law from time to time in effect. In furtherance thereof, the parties hereto and the Holder, by acceptance of
this Non-Convertible Note, stipulate and agree that, as provided in Section 6.13 of the Purchase Agreement, none of the terms and provisions contained therein or herein shall ever be construed to create a contract to pay for the use,
forbearance or detention of money with interest at a rate or in an amount in excess of the Maximum Rate, or to pay an amount of interest in excess of that permitted to be charged under Applicable Law.

indulgences with respect hereto, without notice thereof to any of them. 
 11. No Offsets. The Company agrees that all amounts under
this Non-Convertible Note are payable without set-off, withholding, deduction, claim, counterclaim, defense or recoupment, all of which are hereby waived by the Company. If the indebtedness represented by this Non-Convertible Note or any part hereof
is collected at law or in equity or in bankruptcy, receivership or other judicial proceedings or if this Non-Convertible Note is placed in the hands of attorneys for collection after default, the Company agrees to pay, in addition to the principal
and interest payable hereon, reasonable attorneys’ fees and costs incurred by Holder.
