the Company or any Subsidiary shall default on any of its obligations under any mortgage, credit agreement or other facility,
indenture agreement, factoring agreement or other instrument under which there may be issued, or by which there may be secured
or evidenced, any indebtedness for borrowed money or money due under any long term leasing or factoring arrangement that (a) involves
an obligation greater than $150,000, whether such indebtedness now exists or shall hereafter be created, and (b) results in such
indebtedness becoming or being declared due and payable prior to the date on which it would otherwise become due and payable;

viii.

Transaction); or

 

ix.

(b)
Remedies Upon Event of Default. If any Event of Default occurs, the outstanding principal amount of this Debenture, liquidated
damages and other amounts owing in respect thereof through the date of acceleration, shall become, at the Holder’s election,
immediately due and payable in cash at the Mandatory Default Amount. Commencing 5 days after the occurrence of any Event of Default
that results in the eventual acceleration of this Debenture, the interest rate on this Debenture shall accrue at an interest rate
equal to the lesser of 18% per annum or the maximum rate permitted under applicable law. Upon the payment in full of the Mandatory
Default Amount, the Holder shall promptly surrender this Debenture to or as directed by the Company. In connection with such acceleration
described herein, the Holder need not provide, and the Makers hereby waive, any presentment, demand, protest or other notice of
any kind, and the Holder may immediately and without expiration of any grace period enforce any and all of its rights and remedies
hereunder and all other remedies available to it under applicable law. Such acceleration may be rescinded and annulled by Holder
at any time prior to payment hereunder and the Holder shall have all rights as a holder of the Debenture until such time, if any,
as the Holder receives full payment pursuant to this Section 5(b). No such rescission or annulment shall affect any subsequent
Event of Default or impair any right consequent thereon.

place, and rate, and in the coin or currency, herein prescribed. This Debenture is a direct debt obligation of the Makers.

(d)
Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Debenture shall
be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the
principles of conflict of laws thereof. Each party agrees that all legal proceedings concerning the interpretation, enforcement
and defense of the transactions contemplated by the Bridge Agreement (whether brought against a party hereto or its respective
Affiliates, directors, officers, shareholders, employees or agents) shall be commenced in the state and federal courts sitting
in the City of New York, Borough of Manhattan (the “New York Courts”). Each party hereto hereby irrevocably
submits to the exclusive jurisdiction of the New York Courts for the adjudication of any dispute hereunder or in connection herewith
or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any
suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of such New York Courts, or such New
York Courts are improper or inconvenient venue for such proceeding. Each party hereby irrevocably waives personal service of process
and consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified
mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Debenture
and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein
shall be deemed to limit in any way any right to serve process in any other manner permitted by applicable law. Each party hereto
hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal
proceeding arising out of or relating to this Debenture or the transactions contemplated hereby. If any party shall commence an
action or proceeding to enforce any provisions of this Debenture, then the prevailing party in such action or proceeding shall
be reimbursed by the other party for its attorneys’ fees and other costs and expenses incurred in the investigation, preparation
and prosecution of such action or proceeding.

 

(e)
Waiver. Any waiver by the Makers or the Holder of a breach of any provision of this Debenture shall not operate as or be
construed to be a waiver of any other breach of such provision or of any breach of any other provision of this Debenture. The
failure of the Makers or the Holder to insist upon strict adherence to any term of this Debenture on one or more occasions shall
not be considered a waiver or deprive that party of the right thereafter to insist upon strict adherence to that term or any other
term of this Debenture on any other occasion. Any waiver by the Makers or the Holder must be in writing.

 

(f)
Severability. If any provision of this Debenture is invalid, illegal or unenforceable, the balance of this Debenture shall
remain in effect, and if any provision is inapplicable to any Person or circumstance, it shall nevertheless remain applicable
to all other Persons and circumstances. If it shall be found that any interest or other amount deemed interest due hereunder violates
the applicable law governing usury, the applicable rate of interest due hereunder shall automatically be lowered to equal the
maximum rate of interest permitted under applicable law. The Makers covenant (to the extent that it may lawfully do so) that it
shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension
or usury law or other law which would prohibit or forgive the Makers from paying all or any portion of the principal of this Debenture
as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance
of this Debenture, and the Makers (to the extent it may lawfully do so) hereby expressly waive all benefits or advantage of any
such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein
granted to the Holder, but will suffer and permit the execution of every such as though no such law has been enacted.

(g)
Remedies, Characterizations, Other Obligations, Breaches and Injunctive Relief. The remedies provided in this Debenture
shall be cumulative and in addition to all other remedies available under this Debenture at law or in equity (including a decree
of specific performance and/or other injunctive relief), and nothing herein shall limit the Holder’s right to pursue actual
and consequential damages for any failure by the Makers to comply with the terms of this Debenture. The Makers covenant to the
Holder that there shall be no characterization concerning this instrument other than as expressly provided herein. Amounts set
forth or provided for herein with respect to payments, and the like (and the computation thereof) shall be the amounts to be received
by the Holder and shall not, except as expressly provided herein, be subject to any other obligation of the Makers (or the performance
thereof). The Makers acknowledge that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and
that the remedy at law for any such breach may be inadequate. The Makers therefore agree that, in the event of any such breach
or threatened breach, the Holder shall be entitled, in addition to all other available remedies, to an injunction restraining
any such breach or any such threatened breach, without the necessity of showing economic loss and without any bond or other security
being required. The Makers shall provide all information and documentation to the Holder that is requested by the Holder to enable
the Holder to confirm the Makers’ compliance with the terms and conditions of this Debenture.

 

(h)
Next Business Day. Whenever any payment or other obligation hereunder shall be due on a day other than a Business Day,
such payment shall be made on the next succeeding Business Day.

 

(i)
Headings. The headings contained herein are for convenience only, do not constitute a part of this Debenture and shall
not be deemed to limit or affect any of the provisions hereof.

 

Section
7. Disclosure. Upon receipt or delivery by the Company of any notice in accordance with the terms of this Debenture, unless
the Company has in good faith determined that the matters relating to such notice do not constitute material, nonpublic information
relating to the Company or its Subsidiaries, the Company shall within two (2) Business Days after such receipt or delivery publicly
disclose such material, nonpublic information on a Current Report on Form 8-K or otherwise. In the event that the Company believes
that a notice contains material, non-public information relating to the Company or its Subsidiaries, the Company so shall indicate
to the Holder contemporaneously with delivery of such notice, and in the absence of any such indication, the Holder shall be allowed
to presume that all matters relating to such notice do not constitute material, nonpublic information relating to the Company
or its Subsidiaries.
