0.01    Inability to Determine Rates.

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

(a)If in connection with any request for a Eurodollar Rate Loan or a conversion
to or continuation thereof, (i) the Administrative Agent reasonably determines
that (A) Dollar deposits are not being offered to banks in the London interbank
eurodollar market for the applicable amount and Interest Period of such
Eurodollar Rate Loan, or (B) (1) adequate and reasonable means do not exist for
determining the Eurodollar Rate for any requested Interest Period with respect
to a proposed Eurodollar Rate Loan or in connection with an existing or proposed
Base Rate Loan and (2) the circumstances described in Section 3.03(c)(i) do not
apply (in each case with respect to this clause (i), “Impacted Loans”), or (ii)
the Administrative Agent or the Required Lenders reasonably determine that for
any reason Eurodollar Rate for any requested Interest Period with respect to a
proposed Eurodollar Rate Loan does not adequately and fairly reflect the cost to
such Lenders of funding such Loan, the Administrative Agent will promptly so
notify the Borrower and each Lender. Thereafter, (x) the obligation of the
Lenders to make or maintain Eurodollar Rate Loans shall be suspended (to the
extent of the affected Eurodollar Rate Loans or Interest Periods), and (y) in
the event of a determination described in the preceding sentence with respect to
the Eurodollar Rate component of the Base Rate, the utilization of the
Eurodollar Rate component in determining the Base Rate shall be suspended, in
each case until the Administrative Agent (or, in the case of a determination by
the Required Lenders described in clause (ii) of this Section 3.03(a), until the
Administrative Agent upon instruction of the Required Lenders) revokes such
notice. Upon receipt of such notice, the Borrower may revoke any pending request
for a Borrowing of, conversion to or continuation of Eurodollar Rate Loans (to
the extent of the affected Eurodollar Rate Loans or Interest Periods) or,
failing that, will be deemed to have converted such request into a request for a
Borrowing of Base Rate Loans in the amount specified therein.

(b)Notwithstanding the foregoing, if the Administrative Agent has made the
determination described in clause (a)(i) of this Section 3.03, the
Administrative Agent in consultation with the Borrower, may establish an
alternative interest rate for the Impacted Loans, in which case, such
alternative rate of interest shall apply with respect to the Impacted Loans
until
(i)the Administrative Agent revokes the notice delivered with respect to the
Impacted Loans under clause (a)(i) of this Section 3.03, (ii) the Administrative
Agent or the Required Lenders notify the Administrative Agent and the Borrower
that such alternative interest rate does not adequately and fairly reflect the
cost to the Lenders of funding the Impacted Loans, or (iii) any Lender
determines that any Law has made it unlawful, or that any Governmental Authority
has asserted that it is unlawful, for such Lender or its applicable Lending
Office to make, maintain or fund Loans whose interest is determined by reference
to such alternative rate of interest or to determine or charge interest rates
based upon such rate or any Governmental Authority has imposed material
restrictions on the authority of such Lender to do any of the foregoing and
provides the Administrative Agent and the Borrower written notice thereof.

(a)Notwithstanding anything to the contrary in this Agreement or any other Loan
Documents, but without limiting Sections 3.01(a) and (b) above, if the
Administrative Agent determines (which determination shall be conclusive and
binding upon all parties hereto absent manifest error), or the Borrower or
Required Lenders notify the Administrative Agent (with, in the case of the
Required Lenders, a copy to the Borrower) that the Borrower or Required Lenders
(as applicable) have determined (which determination likewise shall be
conclusive and binding upon all parties hereto absent manifest error), that:

(i)adequate and reasonable means do not exist for ascertaining LIBOR for any
requested Interest Period, including, without limitation, because the LIBOR
Screen Rate is not available or published on a current basis and such
circumstances are unlikely to be temporary; or

(ii)the administrator of the LIBOR Screen Rate or a Governmental Authority

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

having or purporting to have jurisdiction over the Administrative Agent has made
a public statement identifying a specific date after which LIBOR or the LIBOR
Screen Rate shall no longer be made available, or used for determining the
interest rate of loans, provided that, at the time of such statement, there is
no successor administrator that is satisfactory to the Administrative Agent,
that will continue to provide LIBOR after such specific date (such specific
date, the “Scheduled Unavailability Date”); or

(iii)syndicated loans currently being executed, or that include language similar
to that contained in this Section 3.03, are being executed or amended (as
applicable) to incorporate or adopt a new benchmark interest rate to replace
LIBOR, then, reasonably promptly after such determination by the Administrative
Agent or receipt by the Administrative Agent of such notice, as applicable, the
Administrative Agent and the Borrower may amend this Agreement to replace LIBOR
with (x) one or more SOFR-Based Rates or (y) another alternate benchmark rate
giving due consideration to any evolving or then existing convention for similar
U.S. dollar denominated syndicated credit facilities for such alternative
benchmarks and, in each case, including any mathematical or other adjustments to
such benchmark giving due consideration to any evolving or then existing
convention for similar U.S. dollar denominated syndicated credit facilities for
such benchmarks which adjustment or method for calculating such adjustment shall
be published on an information service as selected by the Administrative Agent
from time to time in its reasonable discretion and may be periodically updated
(the “Adjustment;” and any such proposed rate, a “LIBOR Successor Rate”), and
any such amendment shall become effective at 5:00 p.m. on the fifth Business Day
after the Administrative Agent shall have posted such proposed amendment to all
Lenders and the Borrower unless, prior to such time, Lenders comprising the
Required Lenders have delivered to the Administrative Agent written notice that
such Required Lenders (A) in the case of an amendment to replace LIBOR with a
rate described in clause (x), object to the Adjustment; or (B) in the case of an
amendment to replace LIBOR with a rate described in clause (y), object to such
amendment; provided that for the avoidance of doubt, in the case of clause (A),
the Required Lenders shall not be entitled to object to any SOFR-Based Rate
contained in any such amendment. Such LIBOR Successor Rate shall be applied in a
manner consistent with market practice; provided that to the extent such market
practice is not administratively feasible for the Administrative Agent, such
LIBOR Successor Rate shall be applied in a manner as otherwise reasonably
determined by the Administrative Agent.

(b)If no LIBOR Successor Rate has been determined and the circumstances under
clause (c)(i) above exist or the Scheduled Unavailability Date has occurred (as
applicable), the Administrative Agent will promptly so notify the Borrower and
each Lender. Thereafter, (i) the obligation of the Lenders to make or maintain
Eurodollar Rate Loans shall be suspended, (to the extent of the affected
Eurodollar Rate Loans or Interest Periods), and (ii) the Eurodollar Rate
component shall no longer be utilized in determining the Base Rate. Upon receipt
of such notice, the Borrower may revoke any pending request for a Borrowing of,
conversion to or continuation
of Eurodollar Rate Loans (to the extent of the affected Eurodollar Rate Loans or
Interest Periods) or, failing that, will be deemed to have converted such
request into a request for a Borrowing of Base Rate Loans (subject to the
foregoing clause (ii)) in the amount specified therein.

(c)Notwithstanding anything else herein, any definition of LIBOR Successor Rate
shall provide that in no event shall such LIBOR Successor Rate be less than zero
for purposes of this Agreement.

(d)In connection with the implementation of a LIBOR Successor Rate, the
Administrative Agent will have the right to make LIBOR Successor Rate Conforming
Changes from time to time and, notwithstanding anything to the contrary herein
or in any other Loan Document, any amendments

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

appropriate, in the discretion of the Administrative Agent, to reflect the
adoption and implementation of such LIBOR Successor Rate and to permit the
administration thereof by the Administrative Agent in a manner substantially
consistent with market practice (or, if the Administrative Agent determines that
adoption of any portion of such market practice is not administratively feasible

exists, in such other manner of administration as the Administrative Agent
determines is reasonably necessary in connection with the administration of this
Agreement);

“SOFR-Based Rate” means SOFR or Term SOFR; and

(v)“Term SOFR” means the forward-looking term rate for any period that is
approximately (as determined by the Administrative Agent) as long as any of the

that is based on SOFR and that has been selected or recommended by the Relevant

discretion.

such earlier date and (b) no event which is, or with notice or lapse of time or
both would be, an event of default under the Credit Agreement has occurred and
