and the Borrower, the Agreement shall constitute a valid and binding obligation of the Company and the Borrower, enforceable against them in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy,
reorganization, moratorium, liquidation, conservatorship, receivership or similar laws relating to, or affecting generally the enforcement of, creditors rights and remedies or by other equitable principles of general application.



(c) Issuance of Warrants. The Warrants and Warrant Shares have
been duly authorized by all necessary corporate action and, when issued in accordance with the terms

hereof upon surrender of the Exchanged Debt in the Exchange and the exercise of the Warrants, the Warrant Shares shall be
validly issued and outstanding, fully paid and non-assessable, free of restrictions on transfer other than as described herein and under applicable state and federal securities laws, and assuming the accuracy of the Purchasers representations
and warranties set forth in Section 2.2 hereof, such Warrant Shares will have been issued in compliance with all applicable state and federal securities laws.



(d) No Conflicts. The execution, delivery and performance of this Agreement by each of the Company and the Borrower
and the consummation by the Company and the Borrower of the transactions contemplated hereby does not and will not, with respect to each, (i) violate any provision of the Certificate of Incorporation or Bylaws, each as amended to date, (ii) conflict
with, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, mortgage, deed of trust,
indenture, note, bond, license, lease agreement, instrument or obligation to which it is a party or by which any of its properties or assets are bound, or (iii) result in a violation of any federal, state, local or foreign statute, rule, regulation,
order, judgment or decree (including federal and state securities laws and regulations) applicable to it or by which any of its properties or assets are bound or affected, except, in all cases, other than violations pursuant to clauses (i) or (iii)
(with respect to federal and state securities laws) above, except, for such conflicts, defaults, terminations, amendments, acceleration, cancellations and violations as would not, individually or in the aggregate, have a Material Adverse Effect.
Neither the Company nor the Borrower is required under federal, state, foreign or local law, rule or regulation to obtain any consent, authorization or order of, or make any filing or registration with, any court or governmental agency in order for
it to execute, deliver or perform any of its obligations under this Agreement or consummate the Exchange in accordance with the terms hereof (other than any filings, consents and approvals which may be required to be made by the Company under
applicable state and federal securities laws, rules or regulations prior to or subsequent to the Closing).



(e) Offering. No form of general solicitation or general advertising (as defined in Regulation D of the Securities Act of 1933, as amended) was
used by the Company or the Borrower or any of their respective representatives in connection with the offer and sale of the Warrants hereby, including, but not limited to, articles, notices or other communications published in any newspaper,
magazine or similar medium or broadcast over television or radio, or any seminar or other meeting whose attendees have been invited by any general solicitation or general advertising. No securities of the same class as the Warrants or Warrant Shares
have been issued and sold by the Company within the six-month period immediately prior to the date hereof.

relating to, or affecting generally the enforcement of, creditors rights and remedies or by other equitable principles of general application.
