Not later than five days after receipt of notice from the Noteholder, the Guarantor shall pay to the Noteholder an amount equal to the amount of such repayment or return for which the Noteholder has so become liable.

The Guarantor represents that it has obtained the advice of counsel as to the extent to which suretyship and other defenses may be -3- available to it with respect to its obligations hereunder in the absence of the waivers contained in this Section 2.3. No delay or omission on the part of the Noteholder in exercising any right under this Agreement or any other Related Agreement or under any guarantee of the Guaranteed Obligations or with respect to any right under the Security Agreement shall operate as a waiver or relinquishment of such right. No action which the Noteholder or any Obligor may take or refrain from taking with respect to the Guaranteed Obligations, including any amendments thereto or modifications thereof or waivers with respect thereto, shall affect the provisions of this Agreement or the obligations of the Guarantor hereunder. None of the Noteholder's rights shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of any Obligor, or by any noncompliance by any Obligor with the terms, provisions and covenants of the Securities Purchase Agreement or any other Related Agreement, regardless of any knowledge thereof which the Noteholder may have or otherwise be charged with. 2.4. The Noteholder's Power to Waive, etc. The Guarantor grants to the Noteholder full power in its discretion, without notice to or consent of the Guarantor, such notice and consent being expressly waived to the fullest extent permitted by applicable law, and without in any way affecting the liability of the Guarantor under its guarantee hereunder: (a) To waive compliance with, and any Default under, and to consent to any amendment to or modification or termination of any terms or provisions of, or to give any waiver in respect of, the Securities Purchase Agreement, any other Related Agreement, the Guaranteed Obligations or any Guarantee thereof (each as from time to time in effect); (b) To grant any extensions of the Guaranteed Obligations (for any duration), and any other indulgence with respect thereto, and to effect any total or partial release (by operation of law or otherwise), discharge, compromise or settlement with respect to the obligations of any Obligors or any other Person in respect of the Guaranteed Obligations, whether or not rights against the Guarantor under this Agreement are reserved in connection therewith; (c) To take security in any form for the Guaranteed Obligations, and to consent to the addition to or the substitution, exchange, release or other disposition of, or to deal in any other manner with, any part of any property on which a Lien is created under any Security Agreement whether or not the property, if any, received upon the exercise of such power shall be of a character or value the same as or different from the character or value of any property disposed of, and to obtain, modify or release any present or future Guarantees of the Guaranteed Obligations and to proceed -4- against any property on which a Lien is created under any Security Agreement or such Guarantees in any order; (d) To collect or liquidate or realize upon or to refrain from collecting or liquidating or realizing upon any of the Guaranteed Obligations or the property on which a Lien is created under the Security Agreement in any manner. 2.5.

The Guarantor waives any obligation which may now or hereafter exist on the part of the Noteholder to inform it of the risks being undertaken by entering into this Agreement or of any changes in such risks and, from and after the date hereof, the Guarantor undertakes to keep itself informed of such risks and any changes therein. The Guarantor expressly waives any duty which may now or hereafter exist on the part of the Noteholder to disclose to the Guarantor any matter related to the business, operations, character, collateral, credit, condition (financial or otherwise), income or prospects of any Obligor or its Affiliates or their properties or management, whether now or hereafter known by the Noteholder. The Guarantor represents, warrants and agrees that it assumes sole responsibility for obtaining from the Company all information concerning the Securities Purchase Agreement and all other Related Agreements and all other information as to the Obligors and their Affiliates or their properties or management as the Guarantor deems necessary or desirable. 2.6. Certain Guarantor Representations. The Guarantor represents that: (a) it is in its best interest and in pursuit of the purposes for which it was organized as an integral part of the business conducted and proposed to be conducted by the Company and its Subsidiaries, and reasonably necessary and convenient in connection with the conduct of the business conducted and proposed to be conducted by them, to induce the Noteholder to enter into the Securities Purchase Agreement and to extend credit to the Company by making the Guarantee contemplated by this Section 2; (b) the credit available hereunder will directly or indirectly inure to its benefit; (c) by virtue of the foregoing it is receiving at least reasonably equivalent value from the Noteholder for its Guarantee; (d) it will not be rendered insolvent as a result of entering into this Agreement; -5- (e) after giving effect to the transactions contemplated by this Agreement, it will have assets having a fair saleable value in excess of the amount required to pay its probable liability on its existing debts as they become absolute and matured; (f) it has, and will have, access to adequate capital for the conduct of its business; (g) it has the ability to pay its debts from time to time incurred in connection therewith as such debts mature; and (h) it has been advised by the Noteholder that the Noteholder is unwilling to enter into certain Amendments to the Securities Purchase Agreement unless the Guarantee contemplated by this Section 2 is given by it. 2.7.

After the payment in full of the Guaranteed Obligations, the Guarantor shall be entitled to exercise against the Company and any other Obligor all such rights of reimbursement, subrogation, contribution and offset, and all such other claims, to the fullest extent permitted by law. 2.8. Subordination. The Guarantor covenants and agrees that, after the occurrence of an Event of Default, all Indebtedness, claims and liabilities then or thereafter owing by any Obligor to the Guarantor whether arising hereunder or otherwise are subordinated to the prior payment in full of the Guaranteed Obligations and are so subordinated as a claim against such Obligor or any of its assets, whether such claim be in the ordinary course of business or in the event of voluntary or involuntary liquidation, dissolution, insolvency or bankruptcy, so that no payment with respect to any such Indebtedness, claim or liability will be made or received while any Event of Default exists. 2.9. Further Assurances. The Guarantor will, promptly upon the request of the Noteholder from time to time, execute, acknowledge and deliver, and file and record, all such instruments, and take all such action, as the Noteholder deems necessary or advisable to carry out the intent and purposes of this Section 2. 3.
