AGREEMENT

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and as an inducement to the Funding Agents, the Lenders and the Disbursement Agent to enter into the Facility Agreements and the Disbursement Agreement to be entered into concurrently herewith, Completion Guarantor hereby consents and agrees (and each of the other parties hereto agrees and accepts) as follows:

1. Guaranty.

(a) The undersigned Completion Guarantor, as primary obligor and not merely as surety, unconditionally and irrevocably guarantees to each of the Bank Agent, the 2014 Notes Indenture Trustee and any other Agent Beneficiary (i) the performance by the Company of its obligation under the Disbursement Agreement to achieve (A) Final Completion with respect to the Phase I Project and (B) if the Phase II Approval Date occurs on or prior to the Phase II Revolving Commitment Sunset Date, Final Completion with respect to the Phase II Project, (ii) the payment and performance when due, whether by acceleration or otherwise, of the full amount of any and all obligations and liabilities of the Company under Sections 5.5.1 and 5.5.3 of the Disbursement Agreement (the “Relevant Provisions”), and (iii) the payment and performance when due of all other “Secured Obligations” (as defined in the Intercreditor Agreement) of the Loan Parties under each Facility Agreement, whether by acceleration or otherwise, together with all reasonable expenses incurred by the Disbursement Agent or the Lender Beneficiaries in enforcing any of such obligations and liabilities or the terms hereof, including, without limitation, reasonable fees and expenses of legal counsel (collectively, the “Obligations”), and agrees that if for any reason the Company shall fail to pay or perform when due any of such Obligations, Completion Guarantor will pay or perform the same forthwith. Notwithstanding any other provision hereof, Completion Guarantor’s aggregate liability under this Section 1(a), excluding any amounts payable under

Section 18 below and any amounts transferred from the Completion Guaranty Deposit Account to the Company’s Funds Account pursuant to Section 2(e) below, shall in no event exceed Fifty Million Dollars ($50,000,000) plus (x) the amount, if any, required to be deposited by Completion Guarantor in the Completion Guaranty Deposit Account in order for the Company to comply with Section 5.1.3 of the Disbursement Agreement less (y) any amounts released to the Company on the Final Completion Date for the Phase I Project in accordance with Section 2.9.2 of the Disbursement Agreement (the “Liability Cap”). Completion Guarantor waives notice of acceptance of this Guaranty and of any obligation to which it applies or may apply under the terms hereof, and waives diligence, presentment, demand of payment, notice of dishonor or non-payment, protest, notice of protest, of any such obligations, suit or taking other action by the Disbursement Agent or any Lender Beneficiary against, and giving any notice of default or other notice to, or making any demand on, any party liable thereon (including Completion Guarantor).

(b) This Guaranty is an absolute, unconditional, continuing and irrevocable guaranty of payment and not of collectibility and is in no way conditioned on or contingent upon any attempt to enforce in whole or in part the Company’s liabilities and obligations to the Lender Beneficiaries and the Disbursement Agent. Subject to the Liability Cap set forth in Section 1(a) above, if the Company shall fail to pay any of the Obligations as and when they are due, Completion Guarantor shall forthwith pay such Obligations in immediately available funds (provided that any amounts withdrawn from the Completion Guaranty Deposit Account pursuant to Section 2 below (other than clause (c) thereof) shall serve to satisfy such obligation). Each failure by the Company to pay any Obligations shall give rise to a separate cause of action herewith, and separate suits may be brought hereunder as each cause of action arises.

(c) Any Lender Beneficiary may, in accordance with the Financing Agreements or any other Facility Agreement, at any time and from time to time (whether or not after revocation or termination of this Guaranty) without the consent of or notice to Completion Guarantor, except such notice as may be required by the Financing Agreements or any other Facility Agreement or applicable law which cannot be waived, without incurring responsibility to Completion Guarantor, without impairing or releasing the obligations of Completion Guarantor hereunder, upon or without any terms or conditions and in whole or in part, (i) change the manner, place and terms of payment or change or extend the time of payment of, renew, or alter any Obligation, or any obligations and liabilities (including any of those hereunder) incurred directly or indirectly in respect thereof or hereof or in any manner modify, amend or supplement the terms of any Facility Agreement or any other Facility Agreement, the Disbursement Agreement (including the Relevant Provisions) or any documents, instruments or agreements executed in connection therewith (in each case, with the consent of the Company if required by such documents) and the guaranty herein made shall apply to the Obligations as so changed, extended, renewed, modified, amended, supplemented or altered in any manner; (ii) exercise or refrain from exercising any rights against the Company or others (including Completion Guarantor) or otherwise act or refrain from acting; (iii) add or release any other guarantor from its obligations without affecting or impairing the obligations of Completion Guarantor hereunder; (iv) settle or compromise any Obligations and/or any obligations and liabilities (including any of those hereunder) incurred directly or indirectly in respect thereof or hereof, and may subordinate the payment of all or any part thereof to the payment of any obligations and liabilities which may be due to any Lender Beneficiary or others; (v) sell, exchange, release, surrender, realize upon or otherwise deal with in any manner or in any order any property by whomsoever pledged or mortgaged to secure or howsoever securing the Obligations or any liabilities or obligations (including any of those hereunder) incurred directly or indirectly in respect thereof or hereof and/or any offset thereagainst; (vi) apply any sums by whomsoever paid or howsoever realized to any obligations and liabilities of the Company and the other Loan Parties to the Lender Beneficiaries under any of the Financing Agreements or any other Facility Agreement in the manner provided therein regardless of what obligations and liabilities remain unpaid; (vii) consent to or waive any

breach of, or any act, omission or default under, any Financing Agreement or any other Facility Agreement (including the obligation to achieve Final Completion with respect to either Project or the obligations set forth in the Relevant Provisions) or otherwise amend, modify or supplement (with the consent of the Company or other Loan Parties, if required by such documents) any Financing Agreement or any other Facility Agreement (including the obligation to achieve Final Completion with respect to either Project, or the obligations set forth in the Relevant Provisions) or any of such other instruments or agreements; and/or (viii) act or fail to act in any manner referred to in this Guaranty which may deprive Completion Guarantor of any right to subrogation which Completion Guarantor may, notwithstanding the provisions of Section 7, have against the Company or the other Loan Parties to recover full indemnity for any payments made pursuant to this Guaranty or of any right of contribution which Completion Guarantor may have against any other party.

(d) No invalidity, irregularity or unenforceability of the Obligations shall affect, impair, or be a defense to this Guaranty, which is a primary obligation of Completion Guarantor.

(e) This is a continuing Guaranty (subject to Section 2(c) below) and all obligations to which it applies or may apply under the terms hereof shall be conclusively presumed to have been created in reliance hereon. In the event that, notwithstanding the provisions of Section 1(a) hereof, this Guaranty shall be deemed revocable in accordance with applicable law, then any such revocation shall become effective only upon receipt by each Agent Beneficiary and the Disbursement Agent of written notice of revocation signed by Completion Guarantor. No revocation or termination hereof shall affect in any manner rights arising under this Guaranty with respect to Obligations (i) arising prior to receipt by each Agent Beneficiary and the Disbursement Agent of written notice of such revocation or termination and the sole effect of revocation and termination hereof shall be to exclude from this Guaranty any Obligations thereafter arising which are unconnected with Obligations theretofore arising or transactions theretofore entered into or (ii) arising as a result of an Event of Default under the Disbursement Agreement occurring by reason of the revocation or termination of this Guaranty.

(f) If and to the extent required in order for the Obligations of Completion Guarantor to be enforceable under applicable federal, state and other laws relating to the insolvency of debtors, the maximum liability of Completion Guarantor hereunder shall be limited to the greatest amount which can lawfully be guaranteed by Completion Guarantor under such laws, after giving effect to any rights of contribution, reimbursement and subrogation. Completion Guarantor acknowledges and agrees that, to the extent not prohibited by applicable law, (i) it (as opposed to its creditors, representatives of creditors or bankruptcy trustee, including Completion Guarantor in its capacity as debtor in possession exercising any powers of a bankruptcy trustee) has no personal right under such laws to reduce, or request any judicial relief that has the effect of reducing, the amount of its liability under this Guaranty, (ii) it (as opposed to its creditors, representatives of creditors or bankruptcy trustee, including Completion Guarantor in its capacity as debtor in possession exercising any powers of a bankruptcy trustee) has no personal right to enforce the limitation set forth in this Section 1(f) or to reduce, or request judicial relief reducing, the amount of its liability under this Guaranty, and (iii) the limitation set forth in this Section 1(f) may be enforced only to the extent required under such laws in order for the obligations of Completion Guarantor under this Guaranty to be enforceable under such laws and only by or for the benefit of a creditor, representative of creditors or bankruptcy trustee of Completion Guarantor or other Person entitled, under such laws, to enforce the provisions thereof.

(g) Completion Guarantor agrees to pay, and to save the Lender Beneficiaries harmless from, any and all liabilities with respect to, or resulting from any delay in paying, any and all stamp, excise, sales or other taxes which may be payable or determined to be payable in connection with this Guaranty. Completion Guarantor agrees that the provisions of Section 2.20 of the Bank Credit Agreement are hereby incorporated herein by reference, mutatis mutandis, as if Completion

Guarantor were a “Guarantor” under and as defined in the Bank Credit Agreement for purposes only of such provisions, and each Lender Beneficiary shall be entitled to rely on such provisions as if they were fully set forth herein.

2. Completion Guaranty Deposit Account.

(a) As security for Completion Guarantor’s obligations hereunder, Completion Guarantor shall (i) on or prior to the Closing Date, establish or cause to be established the Completion Guaranty Deposit Account and deposit in the Completion Guaranty Deposit Account, in cash or Permitted Investments, Fifty Million Dollars ($50,000,000) and (ii) on the Phase I Substantial Completion Date (if the Phase II Approval Date shall have previously occurred) or on the Phase II Approval Date (if such date occurs after the Phase I Substantial Completion Date), deposit in the Completion Guaranty Deposit Account, in cash or Permitted Investments, any additional amount required to be deposited in the Completion Guaranty Deposit Account in order for the Company to comply with Section 5.1.3 of the Disbursement Agreement, to the extent such Section 5.1.3 is applicable.

(ii) Upon (A) the occurrence of an Event of Default, (B) the dissolution or liquidation of Completion Guarantor, or the Bankruptcy of Completion Guarantor, (C) the breach by Completion Guarantor of any of its obligations hereunder (including its obligations under Section 5) or (D) the occurrence of an Event of Loss, in each case following which the Company is required to transfer amounts on deposit in the Completion Guaranty Deposit Account to the Company’s Funds Account, transfer the full amount of funds then on deposit in the Completion Guaranty Deposit Account to the Company’s Funds Account, and the amounts so transferred shall be deemed to be a dividend from Completion Guarantor to the Company.

(c) On the Completion Guaranty Release Date, the Lender Beneficiaries or the Disbursement Agent shall release or cause to be released the amounts contemplated in Section 2.8(d) of the Disbursement Agreement to the Company, and the amounts so released shall be deemed to be a dividend from Completion Guarantor to the Company. On the Final Completion Date for the Phase I Project, the Lender Beneficiaries or the Disbursement Agent shall release or cause to be released to the Company any amounts in excess of Thirty Million Dollars ($30,000,000), and the amounts so released shall be deemed to be a dividend from Completion Guarantor to the Company. On the Last Project Final Completion Date, (i) the Lender Beneficiaries or the Disbursement Agent shall release or cause to be released all amounts remaining in the Completion Guaranty Deposit Account to the Company, and the amounts so released shall be deemed to be a dividend from Completion Guarantor to the Company and (ii) this Guaranty shall, except for the provisions set forth in Sections 7, 8 and 9 below and subject to Section 19, automatically terminate and be of no force or effect. The provisions of Sections 7, 8 and 9 below shall, subject to Section 19, survive until all the Obligations have been paid in full.

(d) The Agent Beneficiaries or the Disbursement Agent shall apply (or cause to be applied) the proceeds of any withdrawal from the Completion Guaranty Deposit Account under Section 2(b)(i) and Sections 2(b)(ii)(A), (B) and (C) above to the satisfaction of the Company’s obligation to cause funds to be deposited into the Company’s Funds Account or the Disbursement Account, as the case may be, pursuant to Section 5.5.3 of the Disbursement Agreement. The Company shall apply (or cause to be applied) the proceeds of any withdrawal under Section 2(b)(ii)(D) above, as permitted under Section 8 of the Bank Credit Agreement or Article 6 of the 2014 Notes Indenture and, in any event, as otherwise permitted by Section 3 hereof.

(e) The Agent Beneficiaries or the Disbursement Agent shall withdraw or cause to be withdrawn any interest or other earnings which accrue on amounts on deposit in the Completion Guaranty Deposit Account and shall deposit or cause to be deposited such amounts in the Company’s Funds Account, all in accordance with the Completion Guaranty Collateral Account Agreement.

(c) The Disbursement Agent shall take any other steps from time to time requested by the Agent Beneficiaries to confirm or cause the securities intermediary under the Completion Guaranty Collateral Account Agreement to confirm and maintain the priority of the security interests in the Guaranty Collateral.

Guarantor may now have or hereafter acquire against the Company or the other Loan Parties that arises hereunder and/or from the performance by Completion Guarantor hereunder including, without limitation, any claim, remedy or right of subrogation, reimbursement, exoneration, contribution, indemnification, or participation in any claim, right or remedy of the Lender Beneficiaries or the Disbursement Agent against the Company or the other Loan Parties, or any security which the Lender Beneficiaries or the Disbursement Agent now have or hereafter acquire, whether or not such claim, right or remedy arises in equity, under contract, by statute, under common law or otherwise.

9. Bankruptcy.

(a) So long as any of the Obligations are owed to any Lender Beneficiaries, Completion Guarantor shall not commence, or join with any other Person in commencing, any bankruptcy, reorganization, or insolvency proceeding against the Company or any other Loan Party. The obligations of Completion Guarantor under this Guaranty shall not be altered, limited or affected by any proceeding, voluntary or involuntary, involving the bankruptcy, reorganization, insolvency, receivership, liquidation or arrangement of the Company or any other Loan Party, or by any defense which the Company or any other Loan Party may have by reason of any order, decree or decision of any court or administrative body resulting from any such proceeding.

(b) So long as any Obligations are owed to any Lender Beneficiaries, to the extent of such Obligations, Completion Guarantor shall file, in any bankruptcy or other proceeding of or against the Company or any other Loan Party in which the filing of proofs of claims is required or permitted by law, all claims which Completion Guarantor may have against the Company or any other Loan Party (but only to the extent) relating to any indebtedness of the Company or such other Loan Party to Completion Guarantor, and hereby assigns to the Agent Beneficiaries all rights of Completion Guarantor thereunder.
