0000-0000-0000 v.5

Each Releasing Party expressly

4

0000-0000-0000 v.5

acknowledges and agrees, with respect to the Claims, that it waives, to the fullest extent permitted by applicable law, any and all provisions, rights and benefits conferred by any applicable U.S. federal or state law, or any principle of U.S. common law, that would otherwise limit a release or discharge of any unknown Claims pursuant to this Section 7. Furthermore, each of the Releasing Parties hereby absolutely, unconditionally and irrevocably covenants and agrees with and in favor of each Releasee that it will not sue (at law, in equity, in any regulatory proceeding or otherwise) any Releasee on the basis of any Claim released and/or discharged by the Releasing Parties pursuant to this Section 7. The foregoing release, covenant and waivers of this Section 7 shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment or prepayment of any of the Loans, or the termination of the Loan Agreement, this Amendment, any other Loan Document or any provision hereof or thereof.

(b)Each Releasing Party understands, acknowledges and agrees that its release set forth above may be pleaded as a full and complete defense and may be used as a basis for an injunction against any action, suit or other proceeding which may be instituted, prosecuted or attempted in breach of the provisions of such release.

(c)Each Releasing Party agrees that no fact, event, circumstance, evidence or transaction which could now be asserted or which may hereafter be discovered shall affect in any manner the final, absolute and unconditional nature of the release set forth above.

8.Fees and Expenses. The Loan Parties agree to pay on demand all reasonable and documented fees, costs and expenses of the Agent and the Lenders accrued prior to the Third Amendment Effective Date and all reasonable and documented fees, costs and expenses of the Agent and the Lenders incurred in connection with the preparation, execution and delivery of (i) this Amendment, (ii) any Amendment Documents, other Loan Documents or other post-closing amendments, agreements, arrangements or documentation and (iii) any other instruments and documents to be delivered hereunder or thereunder, including, without limitation, the reasonable and documented fees and out-of-pocket expenses of Xxxxxxxx & Xxxxxxxx LLP and DLA Piper Australia, as outside counsel to Agent and the Lenders, with respect thereto.

9.Miscellaneous.

(a)Except as otherwise expressly provided herein, all provisions of the Loan Agreement and the other Loan Documents remain in full force and effect. This Amendment shall constitute a Loan Document.

(b)This Amendment may be executed in several counterparts and by each party on a separate counterpart, each of which when so executed and delivered shall be an original, and all of which together shall constitute one instrument. An executed facsimile or electronic copy of this Amendment shall be effective for all purposes as an original hereof.

(c)This Amendment expresses the entire understanding of the parties with respect to the amendments contemplated hereby. No prior negotiations or discussions shall limit, modify, or otherwise affect the provisions hereof.

5

0000-0000-0000 v.5

(d)This Amendment and the rights and obligations of the parties hereunder shall be governed by, and construed and enforced in accordance with, the law of the State of New York, excluding conflict of laws principles that would cause the application of laws of any other jurisdiction.

(e)Save to the extent expressly provided for in any Loan Document to the contrary, all judicial proceedings (to the extent that the reference requirement of Section 9(f) is not applicable) arising in or under or related to this Amendment may be brought in any state or federal court located in the State of New York. By execution and delivery of this Amendment, each party hereto generally and unconditionally: (a) consents to nonexclusive personal jurisdiction in New York County, State of New York; (b) waives any objection as to jurisdiction or venue in New York County, State of New York; (c) agrees not to assert any defense based on lack of jurisdiction or venue in the aforesaid courts; and (d) irrevocably agrees to be bound by any judgment rendered thereby in connection with this Amendment. Service of process on any party hereto in any action arising out of or relating to this Amendment shall be effective if given in accordance with the requirements for notice set forth in Section 11.2 of the Loan Agreement, and shall be deemed effective and received as set forth in Section 11.2 of the Loan Agreement. Nothing herein shall affect the right to serve process in any other manner permitted by law or shall limit the right of either party to bring proceedings in the courts of any other jurisdiction.

(f)Because disputes arising in connection with complex financial transactions are most quickly and economically resolved by an experienced and expert Person and the parties wish applicable state and federal laws to apply (rather than arbitration rules), the parties desire that their disputes be resolved by a judge applying such applicable laws. EACH OF THE LOAN PARTIES, AGENT AND XXXXXX SPECIFICALLY WAIVES ANY RIGHT IT MAY HAVE TO TRIAL BY JURY OF ANY CAUSE OF ACTION, CLAIM, CROSS-CLAIM, COUNTERCLAIM, THIRD PARTY CLAIM OR ANY OTHER CLAIM (COLLECTIVELY, “CLAIMS”) ASSERTED BY THE LOAN PARTIES AGAINST AGENT, LENDER OR THEIR RESPECTIVE ASSIGNEE OR BY AGENT, LENDER OR THEIR RESPECTIVE ASSIGNEE AGAINST ANY LOAN PARTY. This waiver extends to all such Claims, including Claims that involve Persons other than Agent, the Loan Parties and Lender; Claims that arise out of or are in any way connected to the relationship among the Loan Parties, Agent and Lender; and any Claims for damages, breach of contract, tort, specific performance, or any equitable or legal relief of any kind, arising out of this Agreement or any other Loan Document.

(g)This Amendment and its contents shall be subject to the indemnification and severability provisions of the Existing Loan Agreement, mutatis mutandis.
