Section 3.Amendment.
Effective as of the Amendment and Waiver Effective Date, the final sentence of
Section 2.5(c) of the Credit Agreement is hereby amended and restated as
follows:

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

Notwithstanding the foregoing, no extension of the Maturity Date shall become
effective unless, on the effective date of such extension the conditions set
forth in paragraphs (a) and (b) of Section 4.2 shall be satisfied or waived
(with all references in such paragraphs to a Borrowing being deemed to be
references to the effective date of such extension) and CBNA shall have received
a certificate to that effect dated the effective date of such extension and
executed by a Financial Officer of the Company.

Section 4.Conditions to Effectiveness of Amendment and Waiver.

either (a) a counterpart of this Amendment and Waiver signed on behalf of such
party or (b) written evidence satisfactory to CBNA (which may include email or
facsimile of a signed signature page of this Amendment and Waiver) that such

“Amendment and Waiver Effective Date”).
CBNA shall notify the Company and the Lenders of the Amendment and Waiver
Effective Date, and such notice shall be conclusive and binding absent manifest
error.
Section 5.Effects on Loan Documents.
This Amendment and Waiver shall constitute a “Loan Document” for purposes of the
Credit Agreement and the other Loan Documents. From and after the Amendment and
Waiver Effective Date, all references to the Credit Agreement and each of the
other Loan Documents shall be deemed to be references to the Credit Agreement as

waived pursuant to the terms hereof, all of the representations, warranties,
terms, covenants and conditions of the Loan Documents shall remain unamended and
not waived and shall continue to be in full force and effect. The execution,

expressly provided herein, operate as a waiver of any right, power or remedy of
any Lender or the Administrative Agent under any of the Loan Documents.
Section 6.Miscellaneous.

Agents that (i) the representations and warranties set forth in ‎Article III of

that such representations and warranties qualified as to materiality shall be
true and correct in all respects) on the date hereof, except to the extent such
representations and warranties expressly relate to an earlier date, in which
case such representations and warranties were true and correct in all material
respects (provided that such representations and warranties qualified as to
materiality shall be true and correct in all respects) as of such earlier date
and (ii) no Default or Event of Default exists on the Amendment and Waiver
Effective Date.
(b)This Amendment and Waiver may be executed in multiple counterparts, each of
which shall constitute an original but all of which taken together shall
constitute but one contract.

A counterpart hereof, or signature page hereto, delivered to the Administrative
Agent by facsimile or e-mail shall be effective as delivery of an original
manually-signed counterpart.
(c)The provisions of Sections ‎8.5, ‎8.11, ‎8.13 and ‎8.14 of the Credit
Agreement are incorporated herein by reference as if fully set forth herein,
mutatis mutandis.

THE LAWS OF THE STATE OF NEW YORK.
Section 8.Electronic Execution.
The words “execution,” “signed,” “signature,” and words of like import in this
Amendment and Waiver or in any amendment or other modification hereof (including
waivers and consents) shall be deemed to include electronic signatures or the
keeping of records in electronic form, each of which shall be of the same legal
effect, validity or enforceability as a manually executed signature or the use
of a paper-based recordkeeping system, as the case may be, to the extent and as
provided for in any applicable Law, including the Federal Electronic Signatures
in Global and National Commerce Act, the New York State Electronic Signatures
and Records Act, or any other similar state laws based on the Uniform Electronic
