by the Company in this Agreement and (f) none of the Exchange Agents, any of their affiliates or any of their control persons,
officers, directors or employees shall be liable to the Holder in connection with its exchange of the Exchanged Notes. The Holder
has been represented by such legal and tax counsel and other counsel and advisors selected by the Holder as the Holder has found
necessary to consult concerning this transaction, to review and evaluate the tax, economic and other ramifications of the Exchange,

filing, consent or authorization is required by the Holder, its board of directors, board of managers (or similar governing board)
or its equity holders. This Agreement has been (or upon delivery will have been) duly executed and delivered by the Holder, and
it constitutes the legal, valid and binding obligation of the Holder, enforceable against the Holder in accordance with its terms,

as are necessary in order to evaluate the merits and risks of the Exchange. The Holder is able to bear the economic risk of an
investment in the Exchange Shares and, at the present time, is able to afford a complete loss of its investment. All information
contained in the applications, questionnaires, certifications and documents delivered by the Holder pursuant to this Agreement
is true and correct in all material respects.

    4

not to reoffer or resell the Exchange Shares except pursuant to an exemption from registration under the Act or pursuant to an
effective registration statement thereunder.

 

4.7             
Reliance on Exemptions. The Holder understands
that the Exchange Shares are being offered in the Exchange in reliance on specific exemptions from the registration requirements
of United States federal and state securities laws and that the Company is relying in part upon the truth and accuracy of, and
the Holder’s compliance with, the representations, warranties, agreements, acknowledgments and understandings of the Holder

Commission, including the “Risk Factors” contained therein. The Holder acknowledges and agrees that (a) the Holder

Company, its business, operations, financial performance, financial condition and prospects, and the terms and conditions of the
transactions contemplated by this Agreement and an investment in the Exchange Shares, (c) the Holder has had the opportunity to
consult with its accounting, tax, financial and legal advisors to be able to evaluate the risks involved in the transactions contemplated
by this Agreement and to make an informed investment decision with respect to such transactions, (d) none of the Company or its

persons, officers, directors or employees except for (A) the publicly available filings and submissions made by the Company with
the SEC under the Exchange Act and (B) the representations and warranties made by the Company in this Agreement and (f) none
of the Exchange Agents, any of their affiliates or any of their control persons, officers, directors or employees shall be liable
to the Holder in connection with its exchange of the Exchanged Notes. The Holder has been represented by such legal and tax counsel
and other counsel and advisors selected by the Holder as the Holder has found necessary to consult concerning this transaction,
to review and evaluate the tax, economic and other ramifications of the Exchange, including, without limitation, whether the Exchange
will result in any adverse tax consequences to the Holder.

 

4.9             
Proceedings. The Holder knows of no proceedings
relating to the Exchanged Notes that are pending or threatened before any court, arbitrator or administrative or governmental
body that would adversely affect the completion of the Exchange.
