3.     
Holder Representations. The Holder hereby confirms and acknowledges that the aggregate number of shares of Preferred Stock

4.     
Automatic Preferred Stock Conversion.


 


(a)   
Preferred Stock Conversion. At the Conversion Time, the Preferred Stock Conversion shall automatically take effect without
any action on the part of the Holder such that the Holder shall receive that number of shares of Common Stock (the “Conversion
Shares”) as stipulated therein and as stated on Schedule A attached hereto and the Holder acknowledges, accepts
and authorizes the foregoing Preferred Stock Conversion. To the extent that full conversion of all shares of Preferred Stock held
by the Holder would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to
receive such number of Conversion Shares to such extent (or beneficial ownership of such Conversion Shares as a result of such
Preferred Stock Conversion to such extent) and such portion of such Preferred Stock Conversion to such extent shall be held in
abeyance for the Holder until such time, if ever, as its right thereto would not result in such Holder exceeding the Beneficial
Ownership Limitation (as defined and described below).


 


(b)   Cancellation
of the Preferred Stock. The Holder unconditionally acknowledges, affirms and agrees that simultaneously with the Preferred
Stock Conversion and delivery to the Holder of the Conversion Shares, the Preferred Stock shall be deemed canceled, null and void,
and the Company shall have no further obligation to the Holder with respect to the Preferred Stock or the Certificate of Designation
(except, with respect to the Certificate of Designation only to the extent such full Preferred Stock Conversion is not limited
pursuant to Sections 4(a) and 4(c) herein).

(c)   
Beneficial Ownership Limitation. The Company shall not effect conversion of any Preferred Stock, and the Holder shall not
have the right to exercise nor enforce any such right, pursuant this Section 4, to the extent that after giving effect to the application
of such rights, the Holder (together with the Holder’s Affiliates, and any other persons acting as a group together with
the Holder or any of the Holder’s Affiliates), would beneficially own in excess of the Beneficial Ownership Limitation (as
defined below).  For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder
and its Affiliates shall include the number of shares of Common Stock issuable upon application this Section 4 with respect to
which such determination is being made, but shall exclude the number of shares of Common Stock which would be issuable upon exercise
or conversion of the unexercised or nonconverted portion of any other securities of the Company subject to a limitation on conversion
or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its Affiliates.  Except
as set forth in the preceding sentence, for purposes of this Section 4, beneficial ownership shall be calculated in accordance
with Section 13(d) of the Securities Exchange Act of 1934, as amended (“Exchange Act”) and the rules and regulations
promulgated thereunder, it being acknowledged by the Holder that the Company is not representing to the Holder that such calculation
is in compliance with Section 13(d) of the Exchange Act and the Holder is solely responsible for any schedules required to be filed
in accordance therewith. In addition, a determination as to any group status as contemplated above shall be determined in accordance
with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 4, in
determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding shares of Common
Stock as reflected in (A) the Company’s most recent periodic or annual report filed with the Securities and Exchange Commission,
as the case may be, (B) a more recent public announcement by the Company or (C) a more recent written notice by the Company or
the Company’s transfer agent setting forth the number of shares of Common Stock outstanding.  Upon the written or oral
request of the Holder, the Company shall within three trading days confirm orally and in writing to the Holder the number of shares
of Common Stock then outstanding.  In any case, the number of outstanding shares of Common Stock shall be determined after
giving effect to the conversion or exercise of securities of the Company (subject to any beneficial ownership limitations contained
therein, by the Holder or its Affiliates since the date as of which such number of outstanding shares of Common Stock was reported.
The “Beneficial Ownership Limitation” shall be 4.99%, (unless the Holder elects on its signature page hereto
a different amount as its own Beneficial Ownership Limitation) of the number of shares of the Common Stock outstanding immediately
after giving effect to the issuance of shares of Common Stock issuable upon application of this Section 4 which would not exceed
at such time the Beneficial Ownership Limitation. The Holder, upon not less than 61 days’ prior notice to the Company, may
increase the Beneficial Ownership Limitation provisions of this Section 4 (for the avoidance of doubt, the Holder may on its signature
page hereto to waive such Beneficial Ownership Limitation in its entirety (which such waiver shall be effective 61 days’
after the Closing Date) or set a different amount as its own Beneficial Ownership Limitation) of the number of shares of the Common
Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon application of this Section 4
which would not exceed at such time the Beneficial Ownership Limitation and the provisions of this Section 4 shall continue to
apply. Any such decrease will be effective immediately and any such increase will not be effective until the 61st day
after such notice is delivered to the Company. The provisions of this paragraph shall be construed and implemented in a manner
otherwise than in strict conformity with the terms of this Section 4 to correct this paragraph (or any portion hereof) which may
be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained or to make changes or supplements
necessary or desirable to properly give effect to such limitation. In the event the limitations in this Section 4(c) would prevent
the application of the Holder’s rights under Sections 4(a) or 4(b), then such Holder may exercise all such rights and comply
with all obligations applicable thereto except that the delivery of Common Stock will be deferred until such time as such Holder
provides notice to the Company that such Holder may receive or beneficially own such Common Stock which exceeds the Beneficial
Ownership Limitation applicable to such Holder without exceeding such then applicable Beneficial Ownership Limitation. “Affiliate”
means any person that, directly or indirectly through one or more intermediaries, controls or is controlled by or is under common
control with a person, as such terms are used in and construed under Rule 405 under the Securities Act of 1933, as amended.

foregoing Lock-Up restrictions may only be released or waived prior to the termination of the Lock-Up Period with the written consent
of the Company and Dougherty. Notwithstanding anything to the contrary herein, the Lock-Up restrictions set forth in this Section

Permitted Transfers. Notwithstanding the foregoing, the Holder (and any transferee of the Holder) may transfer any Lock-Up
Securities: (i) as a bona fide gift or gifts, provided that prior to such transfer the donee or donees thereof agree in writing
to be bound by the restrictions set forth herein, (ii) to any trust, partnership, corporation or other entity formed for the direct
or indirect benefit of the Holder or the immediate family of the Holder, provided that prior to such transfer a duly authorized
officer, representative or trustee of such transferee agrees in writing to be bound by the restrictions set forth herein, and provided
further that any such transfer shall not involve a disposition for value, (iii) to non-profit organizations qualified as charitable
organizations under Section 501(c)(3) of the Internal Revenue Code of 1986, as amended, or (iv) if such transfer occurs by operation
of law, such as rules of descent and distribution, statutes governing the effects of a merger or a qualified domestic order, provided
that prior to such transfer the transferee executes an agreement stating that the transferee is receiving and holding Lock-Up Securities
subject to the provisions of this lockup. For purposes hereof, “immediate family” shall mean any relationship by blood,
marriage or adoption, not more remote than first cousin. In addition, the foregoing shall not prohibit privately negotiated transactions,
provided the transferees agree, in writing, to be bound to the terms of this lockup for the balance of the Lock-Up Period

6.     
Independent Nature of Holder's Obligations and Rights. The obligations of the Holder under this Agreement are several and
not joint with the obligations of any Other Buyers, and the Holder shall not be responsible in any way for the performance of the
obligations of any Other Buyer under any Other Agreement. Nothing contained herein, any Other Agreement or the Transaction Documents,
and no action taken by the Holder pursuant hereto, shall be deemed to constitute the Holder and Other Buyers as a partnership,
an association, a joint venture or any other kind of entity, or create a presumption that the Holder and Other Buyers are in any
way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Agreement any Other
Agreement or the Transaction Documents, and the Company acknowledges that the Holder and the Other Buyers are not acting in concert
or as a group with respect to such obligations or the transactions contemplated by this Agreement, any Other Agreement or the Transaction
Documents. The Company and the Holder confirm that the Holder has independently participated in the negotiation of the transactions
contemplated hereby with the advice of its own counsel and advisors. The Holder shall be entitled to independently protect and

Documents, and it shall not be necessary for any Other Buyer to be joined as an additional party in any proceeding for such purpose.


 


7.     
No Third Party Beneficiaries. Except as expressly set forth herein, this Agreement is intended for the benefit of the parties
hereto and their respective permitted successors and assigns, and is not for the benefit of, nor may any provision hereof be enforced
by, any other person.

subsidiaries or any of their respective officers, directors, employees or agents) provided to the Holder.


 


9.     
Most Favored Nation. The Company hereby represents and warrants as of the date hereof and covenants and agrees from and
after the date hereof that none of the terms offered to any person with respect to the transactions contemplated hereby (the conversion
