2.    Amendments to Credit Agreement. Subject to the terms of this Agreement and
in reliance on the representations, warranties, covenants and agreements
contained in this Agreement, as of the Agreement Effective Date, the following
amendments to the Credit Agreement shall be made:
(a)    Section 1.02 of the Credit Agreement (Certain Defined Terms) is hereby
amended by adding the following new definitions in appropriate alphabetical
order therein:
"CARES Act – Title I" means Title I of the Coronavirus Aid, Relief and Economic
Security Act, as amended (including any successor thereto), and all requests,
rules, guidelines, requirements and directives thereunder or issued in
connection therewith or in implementation thereof, regardless of the date
enacted, adopted, issued or implemented.

"CARES Debt" has the meaning set forth in Section 9.02(k).

"CARES Forgiven Debt" means that portion of the CARES Debt that has been finally
determined by the lender of the CARES Debt (and, to the extent required, the
U.S. Small Business Administration) to be eligible for forgiveness pursuant to

been made on or before the date that is six (6) months after the date of
incurrence of the CARES Debt.

"CARES Forgiveness Date" means five (5) Business Days after the date that the
Borrower obtains a final determination by the lender of the CARES Debt (and, to
the extent required, the U.S. Small Business Administration) regarding the
amount of CARES Debt that will be forgiven pursuant to the provisions of the
CARES Act - Title I; provided that if such date is after the date that is six
(6) months after the date of incurrence of the CARES Debt, the full amount of
the CARES Debt will be deemed not eligible to be forgiven.

(d)    Article VII of the Credit Agreement (Representations and Warranties) is
hereby amended by adding the following new Section 7.27 at the end of such
Article as follows:
Section 7.27 CARES Debt. The Borrower has determined in good faith that it is
eligible to apply as a borrower under the Paycheck Protection Program of the
CARES Act – Title I, including the application of the U.S. Small Business
Administration affiliation rule, and has taken into consideration in making such
determination the Interim Final Rule and FAQ #31 issued by the U.S. Small
Business Administration, respectively, on April 23 and 24, 2020, which provides,
among other things that the current economic uncertainty makes the loan request
necessary to support the ongoing operations of the Borrower and its Subsidiaries
taking into account their current business activity and their ability to access
other sources of liquidity sufficient to support their ongoing operations in a
manner that is not significantly detrimental to the business.

(e)    Article VIII of the Credit Agreement (Affirmative Covenants) is hereby
amended by adding the following new Section 8.20 at the end of such Article as
follows:
Section 8.20 CARES Debt.

(a) The Loan Parties shall provide to the Administrative Agent copies of the
definitive loan documentation for CARES Debt promptly upon execution and
delivery thereof by the parties, together with a reasonably detailed estimate of
the amount of Cares Debt that the Loan Parties reasonably anticipate will be
subject to forgiveness pursuant to the provisions of the CARES Act – Title I.

(b)    The Loan Parties shall timely (and, in any event, not later than thirty
(30) days (or such longer period as may be agreed by the Administrative Agent)
after the seven-week anniversary of the initial incurrence thereof) submit all
applications and required documentation necessary or desirable for the lender of
the CARES Debt and/or the U.S. Small Business Administration to make a
determination regarding the amount of the CARES Debt that is eligible to be
forgiven.

(c)    The Loan Parties shall provide to the Administrative Agent copies of any
amendments, modifications, waivers, supplements or consents executed and
delivered with respect to the CARES Debt promptly upon execution and delivery
thereof, and copies of any notices of default received by any Loan Party with
respect to the CARES Debt.

(d)    The Loan Parties shall (i) use all of the proceeds of the CARES Debt
solely for purposes expressly permitted by the CARES Act – Title I and (ii) use
commercially reasonable efforts to conduct their business in a manner that
maximizes the amount of the CARES Debt that is forgiven. Without limiting the
foregoing, the Loan Parties shall cause the proceeds of the CARES Debt to be
deposited into a deposit account that does not sweep funds for the purposes of
satisfying any Obligations or any other Indebtedness, and shall ensure that the
proceeds of the CARES Debt are not used to repay other Indebtedness.

TWELFTH AMENDMENT – Page 3

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

(e)    On the CARES Forgiveness Date, the Loan Parties shall deliver to the
Administrative Agent a certificate of an Authorized Officer of the Loan Parties

the provisions of the CARES Act – Title I, together with a reasonably detailed
description thereof, all in form reasonably satisfactory to the Administrative
Agent.

(f)    Section 9.02(k) of the Credit Agreement (Debt) is hereby restated in its
entirety as follows:

(the “CARES Debt Cap”) advanced by (i) any Governmental Authority (including the
U.S. Small Business Administration) or any other Person acting as a financial

the U.S. Small Business Administration), in each case under clauses (i) and
(ii), pursuant to the CARES Act – Title I (such unsecured Debt, the “CARES
Debt”); provided that, unless otherwise approved by the Administrative Agent (A)
no Event of Default shall have occurred and be continuing at the time of
incurrence thereof and (B) CARES Debt shall (1) be used by the Loan Parties and
their Subsidiaries solely for purposes permitted under the CARES Act - Title I,
(2) have a maturity date not less than two (2) years after the date of
incurrence of the CARES Debt, (3) bear interest at a rate not greater than one
percent (1%) per annum, (4) not require any payments of principal prior to its
stated maturity and (5) otherwise have terms customary for loans made pursuant
to the CARES Act - Title I (taken as a whole); provided further that on the
CARES Forgiveness Date, (x) the CARES Debt Cap shall automatically and without
further action be reduced by the amount of the CARES Debt that is not eligible
to be forgiven under the CARES Act - Title I and (y) the portion of the CARES
Debt not eligible to be forgiven must, if still outstanding, be permitted under
Section 9.02(i); and
