WHEREAS, the Initial Borrower and Nscale Portugal hereby request that the Collateral Agent, with the consent of the Required Lenders, waive the Specified Obligations and, as a consequence, to waive the Specified Default, pursuant to the terms and conditions set forth herein.

NOW, THEREFORE, the parties hereto agree as follows:

Section 1. The Existing Credit Agreement is hereby amended pursuant to Section 9.08(b) of the Existing Credit Agreement by deleting Schedule 2.20 to the Existing Credit Agreement and replacing it in its entirety in the form set forth in Exhibit A hereto.

Section 2. In accordance with Section 9.08(b) of the Credit Agreement, the Collateral Agent, with the consent of the Required Lenders, hereby agrees:

Section 3. This Agreement shall become effective (the “Effective Date”) subject to the satisfaction or waiver by the Administrative Agent of each of the following conditions precedent on the date hereof:

Section 4. In order to induce the Required Lenders and the Collateral Agent to enter into this Agreement, the Initial Borrower represents and warrants that, (i) prior to their respective closures, no Alpha Account was a Collateral Account and each of the Alpha Accounts constituted an Excluded Account and (ii) as of the Effective Date, each of the Alpha Accounts has been closed.

Section 5. Except as expressly set forth herein, this Agreement shall not by implication or otherwise limit, impair, constitute a waiver of or otherwise affect the rights and remedies of any Lender, Loan Party, the Administrative Agent or the Collateral Agent under the Existing Credit Agreement, the Debenture or any other Loan Document, and shall not alter, modify, amend or in any way affect any of the terms, conditions, obligations, covenants or agreements contained in the Existing Credit Agreement, the Debenture or any other Loan Document. For the avoidance of doubt the limited waiver granted under this Consent and Waiver shall not apply to any breach other than the Specified Default. The waiver set forth in this Consent and Waiver is a one-time waiver and is limited to its express terms. Other than as expressly set forth in this Agreement, nothing contained herein shall be construed to modify or in any way amend the Credit Agreement, the Debenture or any other Loan Document. The parties hereto acknowledge and agree that the amendment of the Existing Credit Agreement pursuant to this Agreement shall not constitute a novation of the Existing Credit Agreement. From and after the Effective Date, all references in the Credit Agreement to “this Agreement”, “hereunder”, “hereof” or words of like import referring to the Credit Agreement shall, unless expressly provided otherwise, refer to the Credit Agreement as amended by this Agreement. The Initial Borrower confirms (on behalf of itself and the other Loan Parties) that all obligations of each Loan Party under the Loan Documents to which it is a party shall continue to apply to the Credit Agreement. Without limitation of the foregoing, the Initial Borrower hereby confirms (on behalf of itself and the other Loan Parties) that the indemnification obligations set forth in Section 9.05 of the Credit Agreement shall apply with respect to the execution and delivery of this Agreement.

Section 6. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. The words “execution,” “signed,” “signature” and words of like import in this Agreement 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 Transactions Act.

Section 7. This Agreement shall be construed in accordance with and governed by the laws of the State of New York, without regard to conflict of laws principles thereof to the extent such principles would cause the application of the law of another state.

Section 8. Each of the parties to this Agreement hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of the Supreme Court of the State of New York sitting in New York County and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding shall be heard and determined in such New York State or, to the extent permitted by law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Notwithstanding the foregoing, nothing herein shall affect any right that the Administrative Agent, the Collateral Agent or any Lender may otherwise have to bring any action or proceeding relating to any Loan Document against the Initial Borrower, any other Loan Party or their respective properties in the courts of any jurisdiction.

Section 9. Each of the parties hereto hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any court referred to in Section 8 hereof. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

Section 10. Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 9.15 of the Credit Agreement or Section 27 of the Debenture, as applicable. Nothing herein will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

Section 11. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 11.

Section 12. This Agreement shall constitute a Loan Document for all purposes of the Credit Agreement.

Section 13. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.
