Credit Agreement is hereby amended as follows:

(a) The following defined terms shall be added to Section 1.01 of the Credit
Agreement in alphabetical order:
“Amendment No. 2” means Amendment No. 2 to this Agreement, dated as of April 27,
2018, by and among Wells Fargo, the Borrower and Credit Parties party thereto

other” with a comma and inserting the following at the end of the sentence:
“Amendment No. 1, and”.
(c) The definition of “Letter of Credit Pro Rata Share” in Section 1.01 of the
Credit Agreement is hereby amended by deleting such definition and replacing it
with the following: “means $62,500,000.00 for each of BNS, Natixis, HSBC Canada

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

(e) Section 5.3 of the Credit Agreement is hereby amended by deleting the last

“No Credit Party will, nor will it permit any of its Subsidiaries to, file or
consent to the filing of any consolidated income Tax return with any Person
(other than Parent, Holdings or any of its Subsidiaries). Holdings and Borrower
will not take any affirmative action or consent to any action that (i) would
cause Borrower to be treated as anything other than an entity that is
disregarded as an entity separate from its owner for U.S. Federal income Tax
purposes (including, in each case, the filing of an Internal Revenue Service
Form 8832 electing to be classified as an association taxable as a corporation)
or (ii) would cause a Subsidiary (other than any Subsidiary that is a
corporation or an association taxable as a corporation for U.S. Federal income
Tax purposes as of the Closing Date) to become a corporation or an association
taxable as a corporation for U.S. Federal income Tax purposes if such change to
a Subsidiary, when taken together will all such changes under this clause (ii),
could reasonably be expected to have a Material Adverse Effect.”
(f) The definition of “Permitted Tax Distributions” in Section 1.01 of the
Credit Agreement is hereby amended by deleting such definition and replacing it
with the following:
“means (a) with respect to any taxable period for which Holdings and Borrower
are each treated as a pass through entity for U.S. Federal income Tax purposes,
cash dividends or other distributions or loans declared and paid by Borrower to
Holdings or by Holdings to the members of Holdings, in each case, for the sole
purpose of funding the payments by the members of Holdings of the Taxes owed
with respect to their respective allocable shares of the taxable net income for
such period of Holdings and any of its Subsidiaries treated as pass through
entities for U.S. Federal income Tax purposes (whether owned by Holdings
directly or through other pass-through entities), provided that such dividends
or other distributions shall not exceed, in any taxable period, the product of
(i) the highest marginal effective combined Tax rates then in effect under the
Internal Revenue Code and under the laws of any state and local taxing
jurisdictions in which any member is required to pay income Taxes with respect
to Holdings’ and such Subsidiaries’ combined net income (taking into account the
deductibility of state and local Taxes in computing U.S. Federal income Taxes)
and (ii) net taxable income of Holdings and such Subsidiaries for such taxable
period (computed as if they were a single corporation) reduced by any net losses
or credits or other tax attributes of Holdings or any such Subsidiary carried
over from prior periods to the extent not previously taken into account in
computing payments under this clause (ii) and
(b) with respect to any taxable period for which Holdings is treated as a
corporation for U.S. Federal income Tax purposes, cash dividends or other
distributions declared and paid, or loans made, (i) by Borrower to Holdings for

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

the sole purpose of funding the payment by Holdings of Taxes owed with respect
to Holdings' taxable net income that is attributable to Borrower and any of its
Subsidiaries treated as pass through entities for U.S. Federal income Tax
purposes (whether owned by Borrower directly or through other pass-through
entities); provided that such dividends or other distributions shall not exceed,
in any taxable period, the product of (A) the highest marginal effective
combined Tax rates then in effect under the Internal Revenue Code and under the
laws of any state and local taxing jurisdictions in which Holdings is required
to pay income Taxes (taking into account the deductibility of state and local
Taxes in computing U.S. Federal income Taxes) and (B) net taxable income of
Borrower and such Subsidiaries for such taxable period (computed as if they were
a single corporation) reduced by any net losses or credits or other tax
attributes of Borrower or any such Subsidiary carried over from prior periods to
the extent not previously taken into account in computing payments under this
clause (i) and (ii) by Holdings to any person of which Holdings is a direct or
indirect subsidiary and with whom Holdings files a consolidated, combined,
unitary or affiliated income tax return ("Consolidated Return"), for the sole
purpose of funding the payment by such person of Taxes owed with respect of such
return to the extent such Tax liability is attributable to the income of
Holdings and any Subsidiary of Holdings (the "Holdings Group"); provided that
such dividends or other distributions shall not exceed, in any taxable period,
the amount that the Holdings Group would be required to pay in respect of
Federal, state and local income Taxes for such period, determined by taking into
account any net losses or credits or other tax attributes of the Holdings Group
carried over from prior periods to the extent not previously taken into account
in computing payments under this clause (ii), as if the Holdings Group filed a
separate Consolidated Return.”
