Delivery of an executed counterpart of a signature page to this Amendment by facsimile or in electronic format (i.e., “pdf” or “tif”) shall be effective as delivery of a manually executed counterpart of this Amendment.

Section 4.3. Headings. Section and subsection headings in this Amendment are included herein for convenience only and shall not constitute a part of this Amendment for any other purpose or be given any substantive effect.

Section 4.4. GOVERNING LAW. THIS AMENDMENT AND ALL MATTERS ARISING OUT OF OR RELATING IN ANY WAY WHATSOEVER TO THIS AMENDMENT (WHETHER IN CONTRACT, TORT OR OTHERWISE) SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

Section 4.5. Jurisdiction; Waiver of Jury Trial. The provisions of Sections 10.15 and 10.16 of the Credit Agreement pertaining to consent to jurisdiction, service of process and waiver of jury trial are hereby incorporated by reference therein, mutatis mutandis.

Section 4.6. Reaffirmation. Each Credit Party expressly acknowledges that it has reviewed the terms of this Amendment, consents to the amendments to the Credit Agreement effected pursuant to this Amendment and reaffirms, as of the date hereof and on the Amendment No. 4 Effective Date, that its guarantee (if applicable) of the Obligations under the Credit Agreement and its grant of Liens on the Collateral to secure the Obligations pursuant to each Collateral Document to which it is a party, in each case, continues in full force and effect and extends to the obligations of the Credit Parties under the Credit Documents (including the Amended Credit Agreement) subject to any limitations set out in the Amended Credit Agreement and any other Credit Document applicable to that Credit Party. Neither the execution, delivery, performance or effectiveness of this Amendment nor the modification of the Credit Agreement effected pursuant hereto: (i) impairs the validity, effectiveness or priority of the Liens granted pursuant to any Credit Document, and such Liens continue unimpaired with the same priority to secure repayment of all Obligations, whether heretofore or hereafter incurred; or (ii) requires that any new filings be made or other action be taken to perfect or to maintain the perfection of such Liens.
