EXHIBIT 10.15

AMENDMENT NO. 1 dated as of August 2, 2018 (this “Amendment”), to the CREDIT
AGREEMENT dated as of June 16, 2017 (as amended, supplemented or otherwise
modified prior to the date hereof, the “Credit Agreement”), among FORTRESS
TRANSPORTATION AND INFRASTRUCTURE INVESTORS LLC, a Delaware limited liability
company (the “Borrower”), each lender from time to time party thereto (each
individually referred to therein as a “Lender” and collectively as “Lenders”)
and JPMORGAN CHASE BANK, N.A., as administrative agent (in such capacity, the
“Administrative Agent”).
A. The Borrower has requested that (i) the Aggregate Commitments under the
Credit Agreement be increased by an amount equal to $50,000,000 (the “Commitment
Increase”), which Commitment Increase will be provided by Morgan Stanley Senior
Funding, Inc. (the “Commitment Increase Lender”) and (ii) the Credit Agreement
be amended as set forth herein.
B. The Commitment Increase Lender is willing to provide such additional
Commitments, and the Lenders are willing to so amend the Credit Agreement, in
each case on the terms and subject to the conditions set forth herein.
Accordingly, in consideration of the mutual agreements herein contained and
other good and valuable consideration, the sufficiency and receipt of which are
hereby acknowledged, the parties hereto agree as follows:
SECTION 1. Defined Terms. Capitalized terms used and not defined herein shall
have the meanings assigned to such terms in the Credit Agreement. The rules of
interpretation set forth in Section 1.2 of the Credit Agreement are hereby
incorporated by reference herein, mutatis mutandis.
SECTION 2. Commitment Increase. (a) Subject to the terms and conditions set
forth herein, the Lenders party hereto (including the Commitment Increase
Lender) hereby agree that, effective as of the Amendment Effective Date (as
defined below), the aggregate amount of the Commitments outstanding immediately
prior to the Amendment Effective Date shall be increased by an amount equal to
the Commitment Increase, and that such Commitment Increase shall be held, as of
the Amendment Effective Date, by the Commitment Increase Lender. On and after
the Amendment Effective Date, the Commitment Increase Lender shall, in its
capacity as a Lender, make Loans to the Borrower, and otherwise extend credit
(including by funding participations in Letters of Credit), in each case in
accordance with the terms and subject to the conditions of the Credit Agreement,
as amended hereby. Each Lender agrees that no amounts shall be due under Section
2.15(c) of the Credit Agreement as a result of the transactions contemplated by
this Amendment.
(b)On the Amendment Effective Date, each of the Lenders with Commitments under
the Credit Agreement immediately prior to the Amendment Effective Date (the
“Existing Lenders”), shall assign to the Commitment Increase Lender, and the
Commitment Increase Lender shall purchase from each of such Lenders, at the
principal amount thereof, such interests in the Loans outstanding on the
Amendment Effective Date as shall be necessary in order that, after giving
effect to all such assignments and purchases, the Loans will be held by the
Existing Lenders and the Commitment Increase Lender ratably in accordance with
their Commitments after giving effect to the Commitment Increase, and the
participations in respect of Letters of Credit shall be reallocated so that such
participations are held ratably among the Lenders in accordance with their
commitments after giving effect to the Commitment Increase. Schedule 1.1A of the
Credit Agreement, as amended by this Amendment, sets forth the Commitment of
each Lender after giving effect to this Amendment.
(c)The Commitment Increase Lender, by delivering its signature page to this
Amendment on the Amendment Effective Date, shall be deemed to have acknowledged
receipt of, and consented to and approved, each Loan Document and each other
document required to be delivered to, or be approved by or satisfactory to, the
Administrative Agent or any Lender on the Amendment Effective Date. The
Commitment Increase Lender shall become a “Lender” for all purposes of the
Credit Agreement and the other Loan Documents, in accordance with the terms
thereof, and the Commitment Increase Lender shall have all the rights and
obligations of a Lender under the Credit Agreement with respect to the interests
purchased by it pursuant to such paragraphs, in accordance with the terms
thereof.

--------------------------------------------------------------------------------

SECTION 3. Amendments. Effective as of the Amendment Effective Date, the Credit
Agreement is hereby amended as follows:
(a)The following definitions are hereby added to Section 1.1 of the Credit
Agreement in the appropriate alphabetical order:
(i)“Amendment No. 1”: Amendment No. 1, dated as of August 2, 2018, among the
Borrower, the Lenders party thereto and the Administrative Agent.
(ii)“Amendment Effective Date”: as defined in Amendment No. 1.
(iii)“Beneficial Ownership Certification”: a certification regarding beneficial
ownership as required by the Beneficial Ownership Regulation.
(iv)“Beneficial Ownership Regulation”: 31 C.F.R. § 1010.230.
(v)“NYFRB”: the Federal Reserve Bank of New York.
(vi)“NYFRB Rate”: for any day, the greater of (a) the Federal Funds Effective
Rate in effect on such day and (b) the Overnight Bank Funding Rate in effect on
such day (or for any day that is not a Business Day, for the immediately
preceding Business Day); provided that if none of such rates are published for
any day that is a Business Day, the term “NYFRB Rate” means the rate for a
federal funds transaction quoted at 11:00 a.m. on such day received by the
Administrative Agent from a federal funds broker of recognized standing selected
by it; provided, further, that if any of the aforesaid rates as so determined be
less than zero, such rate shall be deemed to be zero for purposes of this
Agreement.
(vii)“Overnight Bank Funding Rate”: for any day, the rate comprised of both
overnight federal funds and overnight Borrowings with respect to Eurodollar Rate
Loans by U.S.-managed banking offices of depository institutions, as such
composite rate shall be determined by the NYFRB as set forth on its public
website from time to time, and published on the next succeeding Business Day by
the NYFRB as an overnight bank funding rate.
(b)The definition of “Base Rate” is hereby amended and restated in its entirety
as follows:
“Base Rate”: for any day, a rate per annum equal to the greatest of (a) the
Prime Rate in effect on such day, (b) the NYFRB Rate in effect on such day plus
½ of 1% and (c) the Adjusted Eurodollar Rate for a one month Interest Period on
such day (or if such day is not a Business Day, the immediately preceding
Business Day) plus 1%, provided that for the purpose of this definition, the
Adjusted Eurodollar Rate for any day shall be based on the LIBO Screen Rate (or
if the LIBO Screen Rate is not available for such one month Interest Period, the
Interpolated Rate) at approximately 11:00 a.m. London time on such day. Any
change in the Base Rate due to a change in the Prime Rate, the NYFRB Rate or the
Adjusted Eurodollar Rate shall be effective from and including the effective
date of such change in the Prime Rate, the NYFRB Rate or the Adjusted Eurodollar
Rate, respectively. If the Base Rate is being used as an alternate rate of
interest pursuant to Section 2.14 hereof, then the Base Rate shall be the
greater of clause (a) and (b) above and shall be determined without reference to
clause (c) above. For the avoidance of doubt, if the Base Rate shall be less
than zero, such rate shall be deemed to be zero for purposes of this Agreement.
(c)The definition of “Federal Funds Effective Rate” is hereby amended and
restated in its entirety as follows:
“Federal Funds Effective Rate”: for any day, the rate calculated by the NYFRB
based on such day’s federal funds transactions by depositary institutions, as
determined in such manner as the NYFRB shall set forth on its public website
from time to time, and published on the next succeeding Business Day by the
NYFRB as the effective federal funds rate, provided that if the Federal Funds
Effective Rate as so determined would be less than zero, such rate shall be
deemed to zero for the purposes of this Agreement.
(d)The definition of “Prime Rate” is hereby amended and restated in its entirety
as follows:
“Prime Rate” means the rate of interest last quoted by The Wall Street Journal
as the “Prime Rate” in the U.S.

--------------------------------------------------------------------------------

or, if The Wall Street Journal ceases to quote such rate, the highest per annum
interest rate published by the Board in Federal Reserve Statistical Release H.15
(519) (Selected Interest Rates) as the “bank prime loan” rate or, if such rate
is no longer quoted therein, any similar rate quoted therein (as determined by
the Administrative Agent) or any similar release by the Board (as determined by
the Administrative Agent). Each change in the Prime Rate shall be effective from
and including the date such change is publicly announced or quoted as being
effective.
(e)The second recital of the Credit Agreement is hereby amended by deleting
therefrom the dollar amount “$75,000,000” and substituting therefor the dollar
amount “$125,000,000”.
(f)The last sentence of the definition of “Commitment” set forth in Section 1.1
of the Credit Agreement is hereby amended and restated in its entirety to read
as follows: “The aggregate amount of the Commitments as of the Amendment
Effective Date is $125,000,000.”.
(g)Clause (a) of the definition of “Issuing Bank” set forth in Section 1.1 of
the Credit Agreement is hereby amended and restated in its entirety to read as
follows: “(a) JPMorgan Chase Bank, N.A., Barclays Bank PLC and Morgan Stanley
Senior Funding, Inc. (it being understood and agreed that such entities can only
issue standby Letters of Credit) and”.
(h)Clause (a) of the definition of “Maturity Date” set forth in Section 1.1 of
the Credit Agreement is hereby amended by deleting therefrom the date “June 16,
2020” and substituting therefor the date “June 16, 2021”.
(i)Section 2.15(a) of the Credit Agreement is hereby amended and restated in its
entirety to read as follows:
“(a)    Inability to Determine Applicable Interest Rate. (x) If at least two
Business Days prior to the commencement of any Interest Period for a Eurodollar
Rate Loan:
(i)the Administrative Agent determines (which determination shall be conclusive
absent manifest error) that adequate and reasonable means do not exist for
ascertaining the Adjusted Eurodollar Rate or the LIBO Rate, as applicable
(including because the LIBO Screen Rate is not available or published on a
current basis), for such Interest Period; or
(ii)the Administrative Agent is advised by the Required Lenders that the
Adjusted Eurodollar Rate or the LIBO Rate, as applicable, for such Interest
Period will not adequately and fairly reflect the cost to such Lenders of making
or maintaining their Loans included in such Borrowing for such Interest Period;
then the Administrative Agent shall give notice thereof to the Borrower and the
Lenders by telephone, telecopy or electronic mail as promptly as practicable
thereafter and, until the Administrative Agent notifies the Borrower and the
Lenders that the circumstances giving rise to such notice no longer exist, which
the Administrative Agent agrees to do promptly thereafter, (A) any
Conversion/Continuation Notice that requests the conversion of any Loan to, or
continuation of any Loan as, a Eurodollar Rate Loan shall be ineffective and (B)
if any Funding Notice requests a Eurodollar Rate Loan, such Borrowing shall be
made as a Base Rate Loan; provided that if the circumstances giving rise to such
notice affect only one Type of Borrowings, then the other Type of Borrowings
shall be permitted; provided, further, that, in each case, the Borrower may
revoke any Conversion/Continuation Notice or Funding Notice that is pending when
such notice is received.
(y) If at any time the Administrative Agent determines (which determination
shall be conclusive absent manifest error) that (i) the circumstances set forth
in clause (a)(i) have arisen and such circumstances are unlikely to be temporary
or (ii) the circumstances set forth in clause (a)(i) have not arisen but either
(w) the supervisor for the administrator of the LIBO Screen Rate has made a
public statement that the administrator of the LIBO Screen Rate is insolvent
(and there is no successor administrator that will continue publication of the
LIBO Screen Rate), (x) the administrator of the LIBO Screen Rate has made a
public statement identifying a specific date after which the LIBO Screen Rate
will permanently or indefinitely cease to be published by it (and there is no
successor administrator that will continue publication of the LIBO Screen Rate),
(y) the supervisor for the administrator of the LIBO Screen Rate has made a
public statement identifying a specific date after which the LIBO Screen Rate
will permanently or indefinitely cease to be published or (z) the

--------------------------------------------------------------------------------

supervisor for the administrator of the LIBO Screen Rate or a Governmental
Authority having jurisdiction over the Administrative Agent has made a public
statement identifying a specific date after which the LIBO Screen Rate shall no
longer be used for determining interest rates for loans, then the Administrative
Agent and the Borrower shall endeavor to establish an alternate rate of interest
to the LIBO Rate that gives due consideration to the then prevailing market
convention for determining a rate of interest for U.S. Dollar denominated
syndicated loans in the United States at such time, and shall enter into an
amendment to this Agreement to reflect such alternate rate of interest and such
other related changes to this Agreement as may be applicable; provided that, if
such alternate rate of interest as so determined would be less than zero, such
rate shall be deemed to be zero for the purposes of this Agreement.
Notwithstanding anything to the contrary in Section 9.1, such amendment shall
become effective without any further action or consent of any other party to
this Agreement so long as the Administrative Agent shall not have received,
within five Business Days of the date notice of such alternate rate of interest
is provided to the Lenders, a written notice from the Required Lenders stating
that such Required Lenders object to such amendment. Until an alternate rate of
interest shall be determined in accordance with this clause (b) (but, in the
case of the circumstances described in clause (ii) of the first sentence of this
Section 2.12(b), only to the extent the LIBO Screen Rate for such Interest
Period is not available or published at such time on a current basis), (x) any
Conversion/Continuation Notice that requests the conversion of any Loan to, or
continuation of any Loan as, a Eurodollar Rate Loan shall be ineffective and (y)
if any Funding Notice requests a Eurodollar Rate Loan, such Borrowing shall be
made as a Base Rate Loan; provided that, if such alternate rate of interest
shall be less than zero, such rate shall be deemed to be zero for the purposes
of this Agreement.”
(j)Section 3.18 of the Credit Agreement is hereby amended by adding the
following as the last sentence of Section 3.18: “As of the Amendment Effective
Date, the information included in the Beneficial Ownership Certification is true
and correct in all respects.”
(k)Section 5.7 of the Credit Agreement is hereby amended by replacing clause (c)
thereof in its entirety to read as follows:
“(c) any change in the information provided in the Beneficial Ownership
Certification delivered to such Lender that would result in a change to the list
of beneficial owners identified in such certification;”
(l)Section 6.3(b)(1) of the Credit Agreement is hereby amended by deleting
therefrom the dollar amount “$100,000,000” and substituting therefor the dollar
amount “$125,000,000”.
(m)Schedule 1.1A of the Credit Agreement is hereby amended and restated in its
entirety with Schedule 1.1A attached as Exhibit A to this Amendment.
SECTION 4. Representations and Warranties. To induce the other parties hereto to
enter into this Agreement, the Borrower hereby represents and warrants to the
Administrative Agent and each of the other parties hereto that:
