UNSECURED PROMISSORY NOTE



|$3,500,000 |  | December 10, 2014
|---------- |  | -----------------



FOR VALUE RECEIVED, CIG
Wireless Corp., a Nevada corporation (“Borrower”) hereby promises to pay to the order of Fir Tree REF III Tower
LLC, a Delaware limited liability company (the “Holder”), at such place as the holder of this Note may designate
in writing from time to time, in lawful money of the United States, the principal sum of THREE MILLION FIVE HUNDRED THOUSAND DOLLARS
($3,500,000.00), together with accrued interest thereon, as hereinafter provided.



Interest on the principal
balance of this Note shall accrue quarterly at the rate of fifteen percent (15%) per annum, calculated on the basis of a 360 day
year and actual number of days elapsed (but in no event in excess of the maximum rate permitted by applicable law). Interest from
and after maturity (whether as stated or by acceleration) and after the entry of any judgment on this Note shall be at the rate
equal to five percent (5%) per annum above the rate charged hereunder on the date of such maturity (or if such rate shall not be
lawful with respect to Borrower, at the highest lawful rate then in effect). Interest shall be payable quarterly on the last business
day of each March, June, September and December; provided that at the option of Borrower, such interest may be added to the principal
amount of this Note and treated as principal for all purposes hereunder (and accrue further interest from and after such due date
at the applicable interest rate specified above).



Borrower shall pay all
outstanding principal, accrued interest and any other sums outstanding under this Note on the earlier of: (i) August 1, 2018; (ii)
the date on which such amounts due hereunder are accelerated in accordance with the terms of this Note; (iii) the occurrence of
a “Liquidation Event” as defined in the Certificate of Designation (as defined below); or (iv) the date on which Borrower’s
Series A-1 Non-Convertible Preferred Stock is redeemed or redeemable (the “Maturity Date”). If any such date
shall not be a business day, then the scheduled payment shall be due on the next succeeding business day to occur after such date.



At the option of Borrower,
the unpaid principal of this Note may be prepaid in whole or in part, at any time, with accrued and unpaid interest thereon but
without penalty or premium; provided that such any such partial prepayment shall be in an increment of $1,750,000, plus accrued
and unpaid interest thereon.



The liability of Borrower
hereunder shall be unconditional. No act, failure or delay by the Holder hereof to declare a default as set forth herein or to
exercise any right or remedy it may have hereunder, or otherwise, shall constitute a waiver of its rights to declare such default
or to exercise any such right or remedy at such time as it shall determine in its sole discretion.











Borrower shall be in default
under this Note upon the occurrence of any of the following (each, an “Event of Default” and collectively, “Events
of Default”): (a) if Borrower or any of its subsidiaries takes, or seeks or agrees to take, any action in violation
of or which is not in compliance with this Note, including non-payment under this Note on the date when due; (b) any event,
the occurrence or non-occurrence of which, that with the passage of time or the giving of notice, or both, would not be permitted
hereunder or would become a violation of or non-compliance with this Note by Borrower or any of its subsidiaries; (c) any
“default”, “event of default” or any other event, the occurrence or non-occurrence of which, that with
the passage of time or the giving of notice, or both, would be a default or event of default, under (i) any other agreement, document
or instrument (x) to which both Borrower and Holder (or any affiliate thereof (excluding Borrower and its subsidiaries)) are parties
or are otherwise both bound, or (y) any other agreement, document or instrument to which Borrower or any subsidiary of Borrower
is a party or otherwise bound, which, in the case of this clause (y) results in a liability, obligation or otherwise involves a
payment by Borrower or any such subsidiary, in excess of $500,000, (ii) the Senior Debt or (iii) the Certificate of Designation;
(d) any material loss, theft, damage or destruction of any portion of the properties or assets of Borrower or any subsidiary,
which exceeds $500,000, to the extent not covered by insurance; (e) (i) except as contemplated in the “Approved
Budget” (as defined in the Certificate of Designation) for the then current period, a cessation of a substantial part of
the business of Borrower or any subsidiary that is material to Borrower and its subsidiaries, as a whole, (ii) Borrower or
any subsidiary shall suffer the loss or revocation of any material license or permit now held or hereafter acquired by any of them
which is necessary to the continued or lawful operation of its business; (iii) Borrower or any subsidiary shall be enjoined,
restrained or in any way prevented by Governmental Authority from conducting all or any material part of its business affairs;
(iv) any substantial portion of the real property, rights, easements and privileges deemed to be necessary or useful and convenient
for the “Project Towers” or “Existing Towers” (as such terms are defined in the Certificate of Designation)
or in connection therewith, shall be taken through condemnation or the value thereof shall be impaired through condemnation; (f) any
money judgment, writ of attachment or similar processes (collectively, “Judgments”) are issued or rendered against
Borrower or any subsidiary, or any of their respective properties or assets (i) in the case of money Judgments, in an amount
in excess of $100,000 to the extent not covered by insurance, and (ii) in the case of non-monetary Judgments, such Judgment
or Judgments (in the aggregate) could reasonably be expected to have a Material Adverse Effect, in each case, which Judgment is
not stayed, bonded over, released or discharged within 30 days after entry thereof; (g) any violation by Borrower or any subsidiary
of any domestic or foreign, federal, state or local law, rule, regulation, ordinance or similar authority issued, ordered, enacted
or promulgated by any Governmental Authority which could have a Material Adverse Effect; (h) the insolvency of Borrower or
any of its subsidiaries (the term “insolvency” shall mean either a negative tangible net worth or an inability
to pay Borrower’s or such guarantor’s debts as they mature); or (i) the filing by or against Borrower or any of its
subsidiaries of any petition seeking an arrangement, reorganization or the like, the commencement of any proceedings under any
bankruptcy or insolvency law by or against either of them, the adjudication of any of them as a bankrupt, the appointment of a
receiver for all or any part of their respective assets, or the making of an assignment for the benefit of creditors, or the calling
of a meeting of creditors, or the appointment of a committee of creditors or liquidating agents, by, for, or of either of them; provided, however,
that any of the foregoing clauses (a) through and including (i) may be waived by the Holder in its sole discretion by delivering
written notice of such waiver to Borrower. For the avoidance of doubt, any such waiver shall only be effective for the instance
in which it was given, and no waiver shall be effective for any other instance or give rise to any obligation to issue waiver with
respect to any future instance, whether or not prior waivers were given.
