2.Amendments to Credit Agreement. Subject to the satisfaction of the conditions
to effectiveness set forth in Section 3 of this Amendment and in reliance upon
the representations and warranties set forth in Section 4 of this Amendment, the
Credit Agreement is hereby amended as follows:

(a)Section 1.2 of the Credit Agreement is hereby amended by amending and
restating the defined term "Applicable Margin" set forth therein as follows:
"Applicable Margin" shall mean the applicable rate per annum corresponding to
the applicable Senior Net Leverage Ratio, all as set forth in the following
table:

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

Senior Net Leverage Ratio
Prime Rate Loans
LIBOR Rate Loans
> 3.00x
7.25%
8.25%
> 2.50x, but < 3.00x
6.75%
7.75%
>2.00x, but < 2.50x
6.25%
7.25%
<2.00x
6.00%
7.00%

The Applicable Margin shall be adjusted quarterly, to the extent applicable, as
of the first Business Day of the month following the date on which financial
statements are required to be delivered pursuant to Section 9.8 hereof
(including with respect to the last fiscal quarter of each fiscal year) after
the end of each related fiscal quarter based on the Senior Net Leverage Ratio as
of the last day of such fiscal quarter. Notwithstanding the foregoing, (a) until
the first day of the month following the date on which financial statements for
the fiscal quarter ending December 31, 2018 are required to be delivered
pursuant to Section 9.8 hereof, the Applicable Margin shall be (i) 7.25% with
respect to Prime Rate Loans and (ii) 8.25% with respect to LIBOR Rate Loans,
(b) if Borrowers fail to deliver the financial statements required by Section
9.8 hereof, and the related Compliance Certificate required by Section 9.8
hereof, by the respective date required thereunder after the end of any related
fiscal quarter, if requested in writing by Agent or Required Lenders, the
Applicable Margin shall be the rates corresponding to the Senior Net Leverage
Ratio of > 3.00x in the foregoing table until such financial statements and
Compliance Certificate are delivered (plus, if requested by Agent or Required
Lenders, the Default Rate), and (c) no reduction to the Applicable Margin shall
become effective at any time when an Event of Default has occurred and is
continuing; provided, that such a reduction shall occur on the date all such
Events of Default have been cured or waived in accordance with Section 16.2(b)
hereof.
If, as a result of any restatement of or other adjustment to the financial
statements of the Loan Parties or for any other reason, Agent determines that
(a) the Senior Net Leverage Ratio as calculated by Borrowers as of any
applicable date was inaccurate and (b) a proper calculation of the Senior Net
Leverage Ratio would have resulted in different pricing for any period, then (i)
if the proper calculation of the Senior Net Leverage Ratio would have resulted
in higher pricing for such period, Borrowers shall automatically and
retroactively be obligated to pay to Agent, for the benefit of the applicable
Lenders, promptly on demand by Agent, an amount equal to the excess of the
amount of interest that should have been paid for such period over the amount of
interest actually paid for such period; and (ii) if the proper calculation of
the Senior Net Leverage Ratio would have resulted in lower pricing for such
period, neither Agent nor any Lender shall have any obligation to repay any
interest or fees to Borrowers; provided, that, if as a result of any restatement
or other event a proper calculation of the Senior Net Leverage Ratio would have
resulted in higher pricing for one or more periods and lower pricing for one or
more other periods (due to the shifting of income or expenses from one period to
another period or any similar reason), then (x) the amount payable by Borrowers
pursuant to clause (i) above shall be based upon the excess, if any, of the
amount of interest that should have been paid for all applicable periods over
the amount of interest paid for all such periods and (y) the amount credited to
Borrowers pursuant to clause (ii) above shall be based upon the excess, if any,
of the amount of interest paid by Borrowers for all applicable periods over the
amount of interest that should have been paid for all such periods.
