If Borrower shall fail to pay any of the Guaranteed Obligations as and when they are due, Guarantor shall forthwith pay such Guaranteed Obligations in immediately available funds, and each such failure by Borrower to pay a Guaranteed Obligation shall give rise to a separate cause of action herewith, and separate suits may be brought hereunder as each cause of action arises. (b) The Bridge Banks may, 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 Guarantor, except such notice as may be required by applicable law which cannot be waived or any notice required hereunder, without incurring responsibility to Guarantor, without impairing or releasing the obligations of 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 such payment of, renew, or alter any Guaranteed 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 the Bridge Loan Agreement, any documents, instruments or agreements executed in connection therewith, and the guaranty herein made shall apply to the Guaranteed Obligations, as changed, extended, renewed, modified, amended, supplemented or altered in any manner; (ii) exercise or refrain from exercising any rights against Borrower or others (including 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 Guarantor hereunder; (iv) settle or compromise any Guaranteed 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 the Bridge Banks 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 Guaranteed 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 Borrower to the Bridge Banks under the Bridge Loan Agreement or the other Bridge Loan Documents 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, the Bridge Loan Agreement or any other Bridge Loan Document; and/or (viii) act or fail to act in any manner referred to in this Guaranty which may deprive Guarantor of its right to subrogation against Borrower to recover full indemnity for any payments made pursuant to this Guaranty or of its right of contribution against any other party. 7 (c) No invalidity, irregularity or unenforceability of the Guaranteed Obligations or invalidity, irregularity, unenforceability or nonperfection of any collateral therefor, shall affect, impair, or be a defense to this Guaranty, which is a primary obligation of Guarantor. (d) This is a continuing Guaranty 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 2.2(a) hereof, this Guaranty shall be deemed revocable in accordance with applicable law, then to the extent permitted by applicable law any such revocation shall become effective only upon receipt by Administrative Agent of written notice of revocation signed by Guarantor. To the extent permitted by applicable law, no revocation or termination hereof shall affect in any manner rights arising under this Guaranty with respect to Guaranteed Obligations (i) arising prior to receipt by Administrative 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 Guaranteed Obligations thereafter arising which are unconnected with Guaranteed Obligations theretofore arising or transactions theretofore entered into or (ii) arising as a result of an Event of Default under the Bridge Loan Agreement occurring by reason of the revocation or termination of this Guaranty. (e) Guarantor shall file, in any bankruptcy or other proceeding in which the filing of claims is required or permitted by law, all claims which Guarantor may have against Borrower relating to any indebtedness of Borrower to Guarantor, and hereby assigns to Administrative Agent on behalf of the Bridge Banks all rights of Guarantor thereunder. If Guarantor does not file any such claim, Administrative Agent, as attorney-in-fact for Guarantor, is hereby authorized to do so in the name of Guarantor or, in Administrative Agent's discretion, to assign the claim to a nominee and to cause proofs of claim to be filed in the name of Administrative Agent's nominee. The foregoing power of attorney is coupled with an interest and cannot be revoked. Administrative Agent or its nominee shall have the sole right to accept or reject any plan proposed in any such proceeding and to take any other action which a party filing a claim is entitled to take. In all such cases, whether in administration, bankruptcy or otherwise, the person authorized to pay such a claim shall pay the same to Administrative Agent to the extent of any Guaranteed Obligations which then remain unpaid and, to the full extent necessary for that purpose, Guarantor hereby assigns to Administrative Agent all of Guarantor's rights to all such payments or distributions to which Guarantor would otherwise be entitled; provided, however, that Guarantor's obligations hereunder shall not -------- ------- be satisfied except to the extent that Administrative Agent receives cash by reason of any such payment or distribution. If Administrative Agent receives anything hereunder other than cash, the same shall be held as collateral for amounts due under this Guaranty. (f) Except as otherwise required by law, each payment required to be made by Guarantor to Administrative Agent or the Bridge Banks hereunder shall be made without deduction or withholding for or on account of Taxes. If such deduction or withholding is so required, Guarantor shall, upon notice thereof from Administrative Agent, (i) pay the amount required to be deducted or withheld to the appropriate authorities before penalties attach thereto or interest accrues thereon (including deductions from amounts payable under this Section 8 2.2(f)), (ii) on or before the 30th day after payment of such amount, forward to the Bridge Banks an official receipt evidencing such payment (or a certified copy thereof), and (iii) in the case of any such deduction or withholding, forthwith pay to Administrative Agent for the account of the Bridge Banks such additional amount as may be necessary to ensure that the net amount actually received by the Bridge Banks, free and clear of such Taxes, including any Taxes on such additional amount, is equal to the amount that the Bridge Banks would have received had there been no such deduction or withholding. 2.3 Subordination. Except as otherwise specifically provided in this ------------- Guaranty, all existing and future indebtedness of Borrower to Guarantor, and the right of Guarantor to withdraw any capital invested by Guarantor directly or indirectly in Borrower, is hereby subordinated to all obligations and liabilities hereby guaranteed. Without the prior written consent of Administrative Agent, such subordinated indebtedness shall not be paid or withdrawn in whole or in part, nor shall Guarantor accept any payment of or on account of any such indebtedness or as a withdrawal of capital, while this Guaranty is in effect. At Administrative Agent's request, if an Event of Default under the Bridge Loan Agreement has occurred and is continuing, Guarantor shall cause Borrower to pay to Administrative Agent for the benefit of the Bridge Banks all or any part of such subordinated indebtedness and any capital which Guarantor is entitled to withdraw up to the Guaranty Limit. Any payment by Borrower in violation of this Guaranty shall be received by Guarantor in trust for Administrative Agent and the Bridge Banks, and Guarantor shall cause the same to be paid to Administrative Agent for the benefit of the Bridge Banks immediately upon demand by Administrative Agent on account of Borrower's obligations and liabilities hereby guaranteed. Guarantor shall not assign all or any portion of such indebtedness while this Guaranty remains in effect except upon prior written notice to Administrative Agent by which the assignee of any such indebtedness agrees that the assignment is made subject to the terms of this Guaranty, and that any attempted assignment of such indebtedness in violation of the provisions hereof shall be void. Nothing in this Section 2.3 shall apply to any distribution or payment permitted to be made to Guarantor, either Partner or any of their respective Affiliates pursuant to the Credit Documents. 2.4 Waiver. To the extent permitted by applicable law, Guarantor hereby ------ unconditionally and irrevocably waives and relinquishes all rights and remedies accorded by applicable law to sureties or guarantors and agrees not to assert or take advantage of any such rights or remedies, including (a) any right to require Administrative Agent or the Bridge Banks to proceed against Borrower or any other person or to proceed against or exhaust any security held by Administrative Agent or the Bridge Banks at any time or to pursue any other remedy in Administrative Agent's or the Bridge Banks' power before proceeding against Guarantor, (b) any defense that may arise by reason of the incapacity, lack of power or authority, dissolution, merger, termination or disability of Borrower or any other Person or the failure of Administrative Agent or the Bridge Banks to file or enforce a claim against the estate (in administration, bankruptcy or any other proceeding) of Borrower or any other Person, (c) promptness, diligence, demand, presentment, protest and notice of any kind other than notices required hereunder or under the other Bridge Loan Documents, including notice of the existence, creation or incurring of any new or additional indebtedness or obligation or of any action or non-action on the part of Borrower, Administrative Agent, the Bridge Banks, any endorser or creditor of Borrower or Guarantor or on the part of any other person under this or any other 9 instrument in connection with any obligation or evidence of indebtedness held by Administrative Agent or the Bridge Banks in connection with any Guaranteed Obligations, (d) any defense based upon an election of remedies by Administrative Agent or the Bridge Banks, including an election to proceed by non-judicial rather than judicial foreclosure, which destroys or otherwise impairs the subrogation rights of Guarantor, the right of Guarantor to proceed against Borrower for reimbursement, or both, (e) any defense based on any offset against any amounts which may be owed by any Person to Guarantor for any reason whatsoever, (f) any defense based on any act, failure to act, delay or omission whatsoever on the part of Borrower or the failure by Borrower to do any act or thing or to observe or perform any covenant, condition or agreement to be observed or performed by it under the Bridge Loan Agreement or the other Bridge Loan Documents, (g) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal, (h) any defense, setoff or counterclaim which may at any time be available to or asserted by Borrower against Administrative Agent, the Bridge Banks or any other Person under the Bridge Loan Agreement or any other Bridge Loan Document (other than, subject to Section 6.13, defense of payment of the applicable amounts), (i) any duty on the part of Administrative Agent or the Bridge Banks to disclose to Guarantor any facts Administrative Agent or the Bridge Banks may now or hereafter know about Borrower, regardless of whether Administrative Agent or the Bridge Banks have reason to believe that any such facts materially increase the risk beyond that which Guarantor intends to assume, or have reason to believe that such facts are unknown to Guarantor, or have a reasonable opportunity to communicate such facts to Guarantor, since Guarantor acknowledges that Guarantor is fully responsible for being and keeping informed of the financial condition of Borrower and of all circumstances bearing on the risk of non-payment of any obligations and liabilities hereby guaranteed, (j) the fact that Guarantor may at any time in the future dispose of all or part of its direct or indirect interest in Borrower, (k) any defense arising because of Administrative Agent's or the Bridge Banks' election, in any proceeding instituted under the Federal Bankruptcy Code, of the application of Section 1111(b)(2) of the Federal Bankruptcy Code, (l) any defense based upon any borrowing or grant of a security interest under Section 364 of the Federal Bankruptcy Code and (xiii) any other circumstance (including any statute of limitations) or any existence of or reliance on any representation by Administrative Agent or any Bridge Bank that might otherwise constitute a defense available to, or discharge of, any guarantor or surety (other than, subject to Section 6.13, defense of payment of the applicable amounts). 2.5 Subrogation. Until all Bridge Obligations, Credit Obligations, El ----------- Dorado Bridge Obligations and El Dorado Credit Obligations have been paid in full in cash (subject to Section 6.13 and other than those contingent obligations that are intended to survive the termination of the applicable agreement) (a) Guarantor shall not have any right of subrogation and waives all rights to enforce any remedy which it or the Bridge Banks now have or may hereafter have against Borrower in respect of the Guaranteed Obligations, and waives the benefit of, and all rights to participate in, any security now or hereafter held by Administrative Agent or the Bridge Banks from Borrower and (b) Guarantor waives any claim, right or remedy which Guarantor may now have or hereafter acquire against Borrower that arises hereunder, from the existence or enforcement of this Guaranty and/or from the performance by Guarantor hereunder, including any claim, remedy or right of subrogation, reimbursement, exoneration, contribution, indemnification, or participation in any claim, right or remedy of the Bridge Banks against 10 Borrower, or any security which the Bridge Banks 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. 2.6 Bankruptcy. So long as any of the Bridge Obligations, Credit ---------- Obligations, El Dorado Bridge Obligations or El Dorado Credit Obligations remain unsatisfied or unpaid (subject to Section 6.13 and other than those contingent obligations that are intended to survive the termination of the applicable agreement), Guarantor shall not, and shall not permit any of its subsidiaries to, without the prior written consent of Administrative Agent, commence, or join with any other Person in commencing, any bankruptcy, reorganization, or insolvency proceeding against Borrower. The obligations of 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 Borrower, or by any defense which Borrower may have by reason of any order, decree or decision of any court or administrative body resulting from any such proceeding.
