The undersigned
hereby acknowledges, agrees with and represents and warrants to the Company and its affiliates, as follows:

(a)       The
undersigned has full power and authority to enter into this Agreement, the execution and delivery of which has been duly authorized,
if applicable, and this Agreement constitutes a valid and legally binding obligation of the undersigned.

(b)       The

under the Securities Act of 1933, as amended (the “Securities Act”), by virtue of Section 4(a)(2) of the Securities
Act and the provisions of Regulation D promulgated thereunder (“Regulation D”). In furtherance thereof, the
undersigned represents and warrants to the Company and its affiliates as follows:

(i)       The
undersigned is acquiring the Shares solely for the undersigned’s own beneficial account, for investment purposes, and not
with view to, or resale in connection with, any distribution of the Shares;

(ii)       The
undersigned has the financial ability to bear the economic risk of his, her or its investment, has adequate means for providing
for their current needs and contingencies, and has no need for liquidity with respect to the investment in the Company;

(iii       The
undersigned and the undersigned’s attorney, accountant, purchaser representative and/or tax advisor, if any (collectively,
“Advisors”), have received the Term Sheet dated July 7, 2017, together with all appendices thereto and documents
referenced therein (as such documents may be amended or supplemented) (the “Term Sheet”), relating to the conversion

Questionnaire”) is true and accurate in all respects, and the undersigned is an “accredited investor,” as

of evaluating the merits and risks of an investment in the Shares as such are described in the Term Sheet, and each Advisor, if
any, has disclosed to the undersigned in writing (a copy of which is annexed to this Agreement) the specific details of any and

(f)       The
undersigned represents, warrants and agrees that he, she or it will not sell or otherwise transfer the Shares without registration
under the Securities Act or an exemption therefrom, and fully understands and agrees that the undersigned must bear the economic
risk of his, her or its purchase because, among other reasons, the Shares have not been registered under the Securities Act or
under the securities laws of any state and, therefore, cannot be resold, pledged, assigned or otherwise disposed of unless they
are subsequently registered under the Securities Act and under the applicable securities laws of such states, or an exemption from
such registration is available. In particular, the undersigned is aware that the Shares are “restricted securities,”
as such term is defined in Rule 144 promulgated under the Securities Act (“Rule 144”), and they may not be sold pursuant
to Rule 144 unless all of the conditions of Rule 144 are met. The undersigned also understands that, except as described in Section
6 of this Agreement, the Company is under no obligation to register the Shares on his, her or its behalf or to assist them in complying
with any exemption from registration under the Securities Act or applicable state securities laws. The undersigned understands
that any sales or transfers of the Shares are further restricted by state securities laws.

(g)       No
representations or warranties have been made to the undersigned by the Company, other than any representations of the Company contained
herein and in the Term Sheet, and in subscribing for the Shares the undersigned is not relying upon any representations other than
those contained herein or in the Term Sheet.

(h)       The
undersigned understands and acknowledges that his, her or its purchase of the Shares is a speculative investment that involves
a high degree of risk and the potential loss of their entire investment and has carefully read and considered the matters set forth
in the Term Sheet and in the Company’s reports filed with the U.S. Securities and Exchange Commission (“SEC”),
including in particular the matters under the caption “Risk Factors” contained in the Company’s Current Report
on Form 8-K filed with the SEC on November 29, 2016.

(i)       The
undersigned’s overall commitment to investments that are not readily marketable is not disproportionate to the undersigned’s
net worth, and an investment in the Shares will not cause such overall commitment to become excessive.

(j)       The
undersigned understands and agrees that the Shares may bear substantially the following legend until (i) such Shares shall have
been registered under the Securities Act and effectively disposed of in accordance with a registration statement that has been
declared effective or (ii) in the opinion of counsel for the Company such Shares may be sold without registration under the Securities
Act, as well as any applicable “blue sky” or state securities laws:

THE SECURITIES REPRESENTED BY THIS
CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY APPLICABLE
STATE SECURITIES LAWS. SUCH SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT PURPOSES AND MAY NOT BE OFFERED FOR SALE, SOLD, DELIVERED
AFTER SALE, TRANSFERRED, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FILED BY THE ISSUER WITH
THE U.S. SECURITIES AND EXCHANGE COMMISSION COVERING SUCH SECURITIES UNDER THE SECURITIES ACT OR AN OPINION OF COUNSEL SATISFACTORY
TO THE ISSUER THAT SUCH REGISTRATION IS NOT REQUIRED.

(k)       Neither
the SEC nor any state securities commission has approved the Shares or passed upon or endorsed the merits of the Offering or confirmed
the accuracy or determined the adequacy of the Term Sheet. Neither the Term Sheet nor this Offering has been reviewed by any Federal,
state or other regulatory authority.

    	 	4	 

     

    

(l)       The
undersigned and his, her or its Advisors, if any, have had a reasonable opportunity to ask questions of and receive answers from
a person or persons acting on behalf of the Company concerning the Offering of the Shares and the business, financial condition,
results of operations and prospects of the Company, and all such questions have been answered to the full satisfaction of the undersigned
and his, her or its Advisors, if any.

(m)       The
undersigned is unaware of, is in no way relying on, and did not become aware of the Offering of the Shares through or as a result
of, any form of general solicitation or general advertising including, without limitation, any article, notice, advertisement or
other communication published in any newspaper, magazine or similar media or broadcast over television or radio, or electronic
mail over the Internet, in connection with the Offering and sale of the Shares and is not subscribing for Shares and did not become

any solicitation of a subscription by, a person not previously known to the undersigned in connection with investments in securities
generally.

(n)       The
undersigned has taken no action which would give rise to any claim by any person for brokerage commissions, finders’ fees
or the like relating to this Agreement or the transactions contemplated hereby (other than commissions to be paid by the Company
or as otherwise described in the Term Sheet).

(o)       The
undersigned is not relying on the Company with respect to the legal, tax, economic and related considerations of an investment
in the Shares, and the undersigned has relied on the advice of, or has consulted with, only his, her or its own Advisors.
