Section 5.10 Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which taken together shall constitute one and the same instrument. Any counterpart or other signature hereon delivered by facsimile or any standard form of telecommunication or e-mail shall be deemed for all purposes as constituting good and valid execution and delivery of this Agreement by such party. Unless otherwise provided in this Agreement, the words “execute”, “execution”, “signed”, and “signature” and words of similar import used in or related to any document to be signed in connection with this Agreement or any of the transactions contemplated hereby shall be deemed to include electronic signatures and 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 in ink or the use of a paper-based recordkeeping system, as applicable, to the fullest 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, and any other similar state laws based on the Uniform Electronic Transactions Act. Section 5.11 Third Party Beneficiaries. Nothing herein shall grant to or create in any person not a party hereto (other than the Financial Advisor, solely with respect to Article II), or any such person’s dependents or heirs, any right to any benefits hereunder, and no such party shall be entitled to sue any party to this Agreement with respect thereto. Notwithstanding anything in this Agreement to the contrary, any internal or outside counsel to the Company may rely on any and all of the representations, warranties, covenants and agreements contained in this Agreement. Section 5.12 Withholding; Tax Forms. The Company and its agents shall be entitled to deduct and withhold from any consideration payable pursuant to this Agreement such amounts as may be required to be deducted or withheld under applicable law. Without limiting the generality of the foregoing, in the event that a Holder (a) is a “United States person” (as defined in Section

13 AmericasActive:22257337.6 7701(a)(30) of the Internal Revenue Code of 1986, as amended), such Holder shall provide to the Company or its agents an accurately completed and duly executed IRS Form W-9 certifying that such Holder is exempt from backup withholding, or (b) is not a United States person (a “non-U.S. Holder”), such Holder shall provide to the Company or its agents an accurately completed IRS Form W-8BEN-E or another appropriate series of IRS Form W-8, as applicable, which is duly executed by Holder (or its beneficial owners, as required under applicable law). With respect to payments characterized as interest paid to a non-U.S. Holder, such Holder shall either (i) properly establish an exemption from or reduction in U.S. federal withholding under the “interest” provision of a tax treaty with the United States or (ii) provide a tax certificate in the form as reasonably requested by the Company (all such IRS Forms and tax certificates described in this Section 5.12, the “Tax Forms”). Any such amounts withheld or deducted (including, for the avoidance of doubt, due to the failure of a Holder to comply with the obligations set forth in this Section 5.12) shall be treated for all purposes as having been paid to the Holder to whom such amounts otherwise would have been paid and such amounts shall be remitted to the appropriate taxing authority.
