Section 2. Guaranty.

(a) Guarantor hereby irrevocably, absolutely, and unconditionally guarantees to each Guaranteed Party the prompt, complete, and full payment when due, and no matter how the same shall become due, of:

(i) The Note, including all principal, all interest thereon and all other sums payable thereunder; and

(ii) All other sums payable under the other Obligation Documents, whether for principal, interest, fees or otherwise.

Without limiting the generality of the foregoing, Guarantor’s liability hereunder shall extend to and include all post-petition interest, expenses, and other duties and liabilities of each Restricted Person described above in this subsection (a), or below in the following subsection (b), which

would be owed by such Restricted Person but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization, or similar proceeding involving a Restricted Person.

(b) Guarantor hereby irrevocably, absolutely, and unconditionally guarantees to Administrative Agent and each Lender the prompt, complete and full performance, when due, and no matter how the same shall become due, of all obligations and undertakings of the Restricted Persons to Administrative Agent or such Lender under, by reason of, or pursuant to any of the Obligation Documents.

(c) If any Restricted Person shall for any reason fail to pay any Obligation, as and when such Obligation shall become due and payable, whether at its stated maturity, as a result of the exercise of any power to accelerate, or otherwise, Guarantor will, upon demand by Administrative Agent, pay such Obligation in full to Administrative Agent for the benefit of Administrative Agent or the Lender to whom such Obligation is owed. If any Restricted Person shall for any reason fail to perform promptly any Obligation, Guarantor will, upon demand by Administrative Agent, cause such Obligation to be performed or, if specified by Administrative Agent, provide sufficient funds, in such amount and manner as Administrative Agent shall in good faith determine, for the prompt, full and faithful performance of such Obligation by Administrative Agent or such other Person as Administrative Agent shall designate.

(d) If any Restricted Person or Guarantor fails to pay or perform any Obligation as described in the immediately preceding subsections (a), (b), or (c) Guarantor will incur the additional obligation to pay to Administrative Agent, and Guarantor will forthwith upon demand by Administrative Agent pay to Administrative Agent, the amount of any and all reasonable expenses, including fees and disbursements of Administrative Agent’s counsel that are not employees of Administrative Agent or any Affiliate of Administrative Agent and of any experts or agents retained by Administrative Agent, which Administrative Agent may incur as a result of such failure.

(e) As between Guarantor and Administrative Agent or Lenders, this Guaranty shall be considered a primary and liquidated liability of Guarantor.

Section 3. Unconditional Guaranty.

(a) No action which Administrative Agent or any Lender may take or omit to take in connection with any of the Obligation Documents which does not violate the terms thereof, any of the Obligations (or any other indebtedness owing by Borrower to Administrative Agent or any Lender), or any Security, and no course of dealing of Administrative Agent or any Lender with any Obligor or any other Person, shall release or diminish Guarantor’s obligations, liabilities, agreements or duties hereunder, affect this Guaranty in any way, or afford Guarantor any recourse against Administrative Agent or any Lender, regardless of whether any such action or inaction may increase any risks to or liabilities of Administrative Agent or any Lender or any Obligor or increase any risk to or diminish any safeguard of any Security. Without limiting the foregoing, Guarantor hereby expressly agrees that Administrative Agent and Lenders may, from time to time, without notice to or the consent of Guarantor, do any or all of the following:

(i) Amend, change or modify, in whole or in part, any one or more of the Obligation Documents and give or refuse to give any waivers or other indulgences with respect thereto.

(ii) Neglect, delay, fail, or refuse to take or prosecute any action for the collection or enforcement of any of the Obligations, to foreclose or take or prosecute any action in connection with any Security or Obligation Document, to bring suit against any Obligor or any other Person, or to take any other action concerning the Obligations or the Obligation Documents.

(iii) Accelerate, change, rearrange, extend, or renew the time, rate, terms, or manner for payment or performance of any one or more of the Obligations (whether for principal, interest, fees, expenses, indemnifications, affirmative or negative covenants, or otherwise).

(iv) Compromise or settle any unpaid or unperformed Obligation or any other obligation or amount due or owing, or claimed to be due or owing, under any one or more of the Obligation Documents.

(v) Take, exchange, amend, eliminate, surrender, release, or subordinate any or all Security for any or all of the Obligations, accept additional or substituted Security therefor, and perfect or fail to perfect Administrative Agent’s or Lenders’ rights in any or all Security.

(vi) Discharge, release, substitute or add Obligors.

(vii) Apply all monies received from Obligors or others, or from any Security for any of the Obligations, as Administrative Agent or Lenders may determine to be in their best interest, without in any way being required to marshall Security or assets or to apply all or any part of such monies upon any particular Obligations.

(b) No action or inaction of any Obligor or any other Person, and no change of law or circumstances, shall release or diminish Guarantor’s obligations, liabilities, agreements, or duties hereunder, affect this Guaranty in any way, or afford Guarantor any recourse against Administrative Agent or any Lender. Without limiting the foregoing, the obligations, liabilities, agreements, and duties of Guarantor under this Guaranty shall not be released, diminished, impaired, reduced, or affected by the occurrence of any or all of the following from time to time, even if occurring without notice to or without the consent of Guarantor:

(i) Any voluntary or involuntary liquidation, dissolution, sale of all or substantially all assets, marshalling of assets or liabilities, receivership, conservatorship, assignment for the benefit of creditors, insolvency, bankruptcy, reorganization, arrangement, or composition of any Obligor or any other proceedings involving any Obligor or any of the assets of any Obligor under laws for the protection of debtors, or any discharge, impairment, modification, release, or limitation of the liability of, or stay of actions or lien enforcement proceedings

against, any Obligor, any properties of any Obligor, or the estate in bankruptcy of any Obligor in the course of or resulting from any such proceedings.

(ii) The failure by Administrative Agent or any Lender to file or enforce a claim in any proceeding described in the immediately preceding subsection (i) or to take any other action in any proceeding to which any Obligor is a party.

(iii) The release by operation of law of any Obligor from any of the Obligations or any other obligations to Administrative Agent or any Lender.

(iv) The invalidity, deficiency, illegality, or unenforceability of any of the Obligations or the Obligation Documents, in whole or in part, any bar by any statute of limitations or other law of recovery on any of the Obligations, or any defense or excuse for failure to perform on account of force majeure, act of God, casualty, impossibility, impracticability, or other defense or excuse whatsoever.

(v) The fact that Guarantor may have incurred directly part of the Obligations or is otherwise primarily liable therefor.

(vi) Without limiting any of the foregoing, any fact or event (whether or not similar to any of the foregoing) which in the absence of this provision would or might constitute or afford a legal or equitable discharge or release of or defense to a guarantor or surety other than the actual payment and performance by Guarantor under this Guaranty.

(c) This is a guaranty of payment and not of collection. Administrative Agent and Lenders may invoke the benefits of this Guaranty before pursuing any remedies against any Obligor or any other Person and before proceeding against any Security now or hereafter existing for the payment or performance of any of the Obligations. Administrative Agent and Lenders may maintain an action against Guarantor on this Guaranty without joining any other Obligor therein and without bringing a separate action against any other Obligor.

(d) If any payment to Administrative Agent or any Lender by any Obligor is held to constitute a preference or a voidable transfer under applicable state or federal laws, or if for any other reason Administrative Agent or any Lender is required to refund such payment to the payor thereof or to pay the amount thereof to any other Person, such payment to Administrative Agent or such Lender shall not constitute a release of Guarantor from any liability hereunder, and Guarantor agrees to pay such amount to Administrative Agent or such Lender on demand and agrees and acknowledges that this Guaranty shall continue to be effective or shall be reinstated, as the case may be, to the extent of any such payment or payments. Any transfer by subrogation which is made as contemplated in Section 6 prior to any such payment or payments shall (regardless of the terms of such transfer) be automatically voided upon the making of any such payment or payments, and all rights so transferred shall thereupon revert to and be vested in Administrative Agent and Lenders.

(e) This is a continuing guaranty and shall apply to and cover all Obligations and renewals and extensions thereof and substitutions therefor from time to time.

Section 4. Waiver. Guarantor hereby waives, with respect to the Obligations, this Guaranty, and the other Obligation Documents:

(a) notice of the incurrence of any Obligation by any Restricted Person, and notice of any kind concerning the assets, liabilities, financial condition, creditworthiness, businesses, prospects, or other affairs of any Restricted Person (it being understood and agreed that: (i) Guarantor shall take full responsibility for informing itself of such matters, (ii) neither Administrative Agent nor any other Guaranteed Party shall have any responsibility of any kind to inform Guarantor of such matters, and (iii) Guaranteed Parties are hereby authorized to assume that Guarantor, by virtue of its relationships with Borrower which are independent of this Guaranty, has full and complete knowledge of such matters whenever Guaranteed Parties extend credit to any Restricted Person or take any other action which may change or increase Guarantor’s liabilities or losses hereunder).

(b) notice that Administrative Agent, any Lender, any Obligor, or any other Person has taken or omitted to take any action under any Obligation Document or any other agreement or instrument relating thereto or relating to any Obligation.

(d) notice of intention to accelerate, notice of acceleration, protest, notice of protest, notice of any exercise of remedies (as described in the following Section 5 or otherwise), and all other notices of any kind whatsoever.

Section 5. Exercise of Remedies. Administrative Agent shall have the right to enforce, from time to time, in any order and at Administrative Agent’s sole discretion, any rights, powers and remedies which Administrative Agent or Lenders may have under the Obligation Documents or otherwise, including judicial foreclosure, the exercise of rights of power of sale, the taking of a deed or assignment in lieu of foreclosure, the appointment of a receiver to collect rents, issues and profits, the exercise of remedies against personal property, or the enforcement of any assignment of leases, rentals, oil or gas production, or other properties or rights, whether real or personal, tangible or intangible; and Guarantor shall be liable to Administrative Agent and each Lender hereunder for any deficiency resulting from the exercise by Administrative Agent of any such right or remedy even though any rights which Guarantor may have against Borrower or others may be destroyed or diminished by exercise of any such right or remedy. No failure on the part of Administrative Agent or any Lender to exercise, and no delay in exercising, any right hereunder or under any other Obligation Document shall operate as a waiver thereof; nor shall any single or partial exercise of any right preclude any other or further exercise thereof or the exercise of any other right. The rights, powers and remedies of Administrative Agent and each Lender provided herein and in the other Obligation Documents are cumulative and are in addition to, and not exclusive of, any other rights, powers or remedies provided by law or in equity. The rights of Administrative Agent and each Lender hereunder are not conditional or contingent on any attempt by Administrative Agent or any Lender to exercise any of its rights under any other Obligation Document against any Obligor or any other Person.

Section 6. Limited Subrogation.

(a) Until all of the Obligations have been paid and performed in full Guarantor shall have no right to exercise any right of subrogation, reimbursement, indemnity, exoneration, contribution or any other claim which it may now or hereafter have against or to any Obligor or any Security in connection with this Guaranty, and Guarantor hereby waives any rights to enforce any remedy which Guarantor may have against any Restricted Person and any right to participate in any Security until such time. If any amount shall be paid to Guarantor on account of any such subrogation or other rights, any such other remedy, or any Security at any time when all of the Obligations and all other expenses guaranteed pursuant hereto shall not have been paid in full, such amount shall be held in trust for the benefit of Administrative Agent, shall be segregated from the other funds of Guarantor and shall forthwith be paid over to Administrative Agent to be held by Administrative Agent as collateral for, or then or at any time thereafter applied in whole or in part by Administrative Agent against, all or any portion of the Obligations, whether matured or unmatured, in such order as Administrative Agent shall elect.

(b) If Guarantor shall make payment to Administrative Agent of all or any portion of the Obligations and if all of the Obligations shall be finally paid in full in cash, Administrative Agent will, at Guarantor’s request and expense, execute and deliver to Guarantor (without recourse, representation or warranty) appropriate documents necessary to evidence the transfer by subrogation to Guarantor of an interest in the Obligations resulting from such payment by Guarantor; provided that such transfer shall be subject to Section 3(d) above and that without the consent of Administrative Agent (which Administrative Agent may withhold in its discretion) Guarantor shall not have the right to be subrogated to any claim or right against any Obligor which has become owned by Administrative Agent or any Lender, whose ownership has otherwise changed in the course of enforcement of the Obligation Documents.

Section 7. Successors and Assigns. Guarantor’s rights or obligations hereunder may not be assigned or delegated, but this Guaranty and such obligations shall pass to and be fully binding upon the successors of Guarantor, as well as Guarantor. This Guaranty shall apply to and inure to the benefit of Administrative Agent and Lenders and their successors or assigns who acquire their interests in accordance with the assignment provisions of the Credit Agreement. Without limiting the generality of the immediately preceding sentence, Administrative Agent and each Lender may assign, grant a participation in, or otherwise transfer any Obligation held by it or any portion thereof, and Administrative Agent and each Lender may assign or otherwise transfer its rights or any portion thereof under any Obligation Document, to any other Person, and such other Person shall thereupon become entitled to all of the benefits in respect thereof granted to Administrative Agent or such Lender hereunder unless otherwise expressly provided by Administrative Agent or such Lender in connection with such assignment or transfer.

Section 8. Subordination and Set Off. Guarantor hereby subordinates and makes inferior to the Obligations any and all indebtedness now or at any time hereafter owed by Restricted Persons to Guarantor. Guarantor agrees that after the occurrence and during the continuance of any Event of Default (including the commencement and continuation of any proceeding under any Debtor Relief Law relating to any Restricted Person) it will neither permit any Restricted Person to repay such indebtedness or any part thereof nor accept payment from any Restricted Person of such indebtedness or any part thereof without the prior written consent

of Administrative Agent. If Guarantor receives any such payment without the prior written consent of Administrative Agent, the amount so paid shall be held in trust for the benefit of Lenders, shall be segregated from the other funds of Guarantor, and shall forthwith be paid over to Administrative Agent to be held by Administrative Agent as collateral for, or then or at any time thereafter applied in whole or in part by Administrative Agent against, all or any portions of the Obligations, whether matured or unmatured, in such order as Administrative Agent shall elect. In any proceeding under any Debtor Relief Law relating to any Restricted Person, the Guaranteed Parties shall be entitled to receive payment in full in cash of all Obligations (including all interest and expenses accruing after the commencement of a proceeding under any Debtor Relief Law, whether or not constituting an allowed claim in such proceeding) before Guarantor receives payment of any Subordinated Obligation.

If an Event of Default shall have occurred and be continuing, each Guaranteed Party is hereby authorized at any time and from time to time after obtaining the prior written consent of Administrative Agent, to the fullest extent permitted by applicable Law, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held and other obligations (in whatever currency) at any time owing by such Guaranteed Party to or for the credit or the account of Guarantor against any and all of the obligations of Guarantor now or hereafter existing under this Guaranty to such Guaranteed Party. The rights of each Guaranteed Party under this Section are in addition to other rights and remedies (including other rights of set off) that such Guaranteed Party may have.

Section 9. Representations and Warranties. Guarantor hereby represents and warrants to Administrative Agent and each Lender as follows:

(a) The Recitals at the beginning of this Guaranty are true and correct in all respects.

(b) Guarantor is an entity duly organized, validly existing and in good standing under the laws of the state of its organization as set forth in the Recitals to this Guaranty; and Guarantor has all requisite power and authority to execute, deliver and perform this Guaranty.

(c) The execution, delivery and performance by Guarantor of this Guaranty have been duly authorized by all necessary corporate action and do not and will not contravene its certificate or articles of incorporation or bylaws.

(e) No authorization or approval or other action by, and no notice to or filing with, any governmental authority or other regulatory body or third party is required for the due execution, delivery and performance by Guarantor of this Guaranty, other than reporting requirements to the ASX, with which Guarantor agrees to comply.

(f) This Guaranty is a legal, valid and binding obligation of Guarantor, enforceable against Guarantor in accordance with its terms except as limited by bankruptcy, insolvency or

similar laws of general application relating to the enforcement of creditors’ rights and general principles of equity.

(h) The direct or indirect value of the consideration received and to be received by Guarantor in connection herewith is reasonably worth at least as much as the liability and obligations of Guarantor hereunder, and the incurrence of such liability and obligations in return for such consideration may reasonably be expected to benefit Guarantor, directly or indirectly.
