SECTION 2. GUARANTY

2.1 Guaranty. Guarantor hereby absolutely, unconditionally and irrevocably guarantees to the Holder, the prompt and complete payment and performance by the Purchaser and Éclat of the Obligations when due (whether at the stated maturity, by acceleration or otherwise).

 2.2 Nature of Guaranty. Guarantor’s liability under this Guaranty shall be unlimited, open and continuous for so long as this Guaranty remains in force. Guarantor intends to guaranty the performance and prompt payment of the Obligations when due, whether at maturity or earlier by reason of acceleration or otherwise. Accordingly, no payments made upon the Obligations will discharge or diminish the continuing liability of Guarantor in connection with any remaining portions of the Obligations which subsequently arises or is thereafter incurred. No payment made by the Purchaser or Éclat, or any other Person or received or collected by the Holder from the Purchaser or Éclat, or any other Person by virtue of any action or other proceeding or any set-off or appropriation or application at any time or from time to time in reduction of or in payment of the Obligations shall be deemed to modify, reduce, release or otherwise affect the liability of Guarantor hereunder which shall, notwithstanding any such payment (other than payment and performance in full of the Obligations), remain liable for the Obligations until the Obligations are paid and performed in full.

2.3 Duration of Guaranty. This Guaranty will take effect when received by the Holder without the necessity of any acceptance by the Holder, or any notice to Guarantor, and will continue in full force until the Obligations shall have been fully paid and satisfied and all other obligations of Guarantor under this Guaranty shall have been performed in full. All renewals, extensions, substitutions, and modifications of the Obligations, release of any other guarantor or termination of any other guaranty of the Obligations shall not affect the liability of Guarantor under this Guaranty. This Guaranty is irrevocable and is binding upon Guarantor and Guarantor’s successors and assigns so long as any of the Obligations remain unpaid.

2.4 No Subrogation. Notwithstanding any payment made by Guarantor hereunder or any set-off or application of funds of Guarantor by the Holder, Guarantor shall not be entitled to be subrogated to any of the rights of the Holder against the Purchaser or Éclat or any other guarantor or guaranty or right of offset held by the Holder for the payment of the Obligations, nor shall Guarantor seek or be entitled to seek any contribution or reimbursement from the Purchaser or Éclat or any other guarantor in respect of payments made by Guarantor hereunder, until all amounts owing to the Holder by the Purchaser or Éclat on account of the Obligations are paid in full. If any amount shall be paid to Guarantor on account of such subrogation rights at any time when all of the Obligations shall not have been paid in full, such amount shall be held in trust for the benefit of the Holder, segregated from other funds of Guarantor, and shall, forthwith upon receipt by Guarantor, be turned over to the Holder in the exact form received by such Guarantor (duly indorsed by Guarantor to the Holder, if required), to be applied against the Obligations, whether matured or unmatured, in such order as the Holder may determine.

2.5 Amendments, Etc. With Respect to The Obligations. Guarantor shall remain obligated hereunder notwithstanding that, without any reservation of rights against Guarantor and without notice to or further assent by Guarantor, any demand for payment or performance of any of the Obligations made by the Holder may be rescinded by the Holder and any of the Obligations continued, and the Obligations, or the liability of any other Person upon or for any part thereof, or guaranty therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by the Holder, and the Note Agreement and, the Security Agreements and the Interest Agreement and any other documents executed and delivered in connection therewith may be amended, modified, supplemented or terminated, in whole or in part, as the Holder may deem advisable from time to time, and any guaranty or right of offset at any time held by the Holder for the payment of the Obligations may be sold, exchanged, waived, surrendered or released.

 2.6 Guaranty Absolute and Unconditional. Guarantor hereby waives any and all notice of the creation, renewal, extension or accrual of any of the Obligations and notice of or proof of reliance by the Holder upon the guaranty contained in this Section 2 or acceptance of the guaranty contained in this Section 2; the Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred, or renewed, extended, amended or waived, in reliance upon the guaranty contained in this Section 2; and all dealings between the Purchaser and Éclat and Guarantor, on the one hand, and the Holder, on the other hand, likewise shall be conclusively presumed to have been had or consummated in reliance upon the guaranty contained in this Section 2. Guarantor hereby waives, to the extent permitted by law, diligence, presentment, protest, demand for payment and notice of default or nonpayment to or upon the Purchaser or Éclat or Guarantor with respect to the Obligations. Guarantor understands that the guaranty contained in this Section 2 shall be construed as a continuing, absolute and unconditional guaranty of payment and performance without regard to (a) the validity or enforceability of the Note Agreement, the Security Agreements and the Interest Agreement, any of the Obligations or any other guaranty or right of offset with respect thereto at any time or from time to time held by the Holder, (b) any defense, set-off or counterclaim (other than a defense of actual payment and performance of all Obligations) which may at any time be available to or be asserted by the Purchaser or Éclat or any other Person against the Holder, or (c) any other circumstance whatsoever (with or without notice to or knowledge of Guarantor) which constitutes, or might be construed to constitute, an equitable or legal discharge of the Purchaser or Éclat for the Obligations, or of Guarantor under the guaranty contained in this Section 2, in bankruptcy or in any other instance. When making any demand hereunder or otherwise pursuing its rights and remedies hereunder against Guarantor, the Holder may, but shall be under no obligation to, make a similar demand on or otherwise pursue such rights and remedies as they may have against the Purchaser or Éclat or any other Person or against any other guaranty for the Obligations or any right of offset with respect thereto, and any failure by the Holder to make any such demand, to pursue such other rights or remedies or to collect any payments from the Purchaser or Éclat or any other Person or to realize upon any such other guaranty or to exercise any such right of offset, or any release of the Purchaser or Éclat or any other Person or any such other guaranty or right of offset, shall not relieve Guarantor of any obligation or liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of the Holder against Guarantor.

The obligations of the Guarantor are principal and independent obligations from the obligations of the parties to the Note Agreement, the Security Agreements, the Interest Agreement or any other agreement. Therefore, the Guarantor cannot, in order to delay or to avoid the unconditional and immediate performance of its obligations under this Guaranty, invoke any defense or exception relating to or resulting from any current or future relationships (including legal relationships) nor any contentious or non-contentious claims, between the Purchaser and the Holder or any other third party, or any other challenge or the Purchaser or of a third party.

 2.7 Reinstatement. The guaranty contained in this Section 2 shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Obligations is rescinded or must otherwise be restored or returned by the Holder upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Purchaser or Éclat, Guarantor or any other guarantor of the Obligations, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for the Purchaser or Éclat, Guarantor or any other guarantor of the Obligations or any substantial part of its property, or otherwise, all as though such payments had not been made.

2.8 Payments. Guarantor hereby guarantees that payments hereunder will be paid to the Holder without set-off or counterclaim in U.S. dollars at the address set forth in the Note Agreement or by wire transfer pursuant to instructions provided to Guarantor by the Holder.

If any such waiver is determined to be contrary to any applicable law or public policy, such waiver shall be effective only to the extent permitted by law or public policy.

5.3 Subordination of Debts to Guarantor. The Obligations shall be prior to any claim that Guarantor may now have or hereafter acquire against the Purchaser or Éclat, whether or not the Purchaser or Éclat becomes insolvent.

The Holder shall notify Guarantor promptly of any such set-off and the application made by the Holder of the proceeds thereof, provided that the failure to give such notice shall not affect the validity of such set-off and application.
