For purposes of this Agreement, but without limiting the foregoing, a change in any rate of interest, discount rate or commissions or fees charged by either factor under either’s factoring agreement shall not be deemed to be a change of a material term of the factoring agreement.

3. Consents.

3.1 MCF’s Consent to Sale and Security Interest. MCF acknowledges and agrees that, notwithstanding any contrary provision contained in the MCF Documents, the Company may: (i) sell and assign its Non-Domestic Accounts to FGI and (ii) grant a security interest to FGI in the FGI Collateral, and further acknowledges and agrees that such sale and grant of security interest shall not constitute a default or event of default by the Company under the MCF Documents or any related agreement or instrument. MCF hereby releases and discharges any security interest in the Non-Domestic Accounts purchased by FGI (“FGI Purchased Accounts”) and hereby waives any and all claims or interest it has or might have in and with respect to the FGI Purchased Accounts, regardless of (i) when its interest became perfected, (ii) when the FGI Purchased Accounts were purchased, (iii) the value of the FGI Purchased Accounts, (iv) the consideration given or promised therefore, or (v) the amount FGI is owed by the Company. MCF waives, releases and discharges any interest it has or might have in any FGI Purchased Accounts as representative of the proceeds of any of the Company’s inventory or any payments received by FGI on the FGI Purchased Accounts as well as all goods returned under the FGI Purchased Accounts.

3.2 FGI’s Consent to Sale and Security Interest. FGI acknowledges and agrees that, notwithstanding any contrary provision contained in the FGI Documents, the Company may: (i) sell and assign its Domestic Accounts to MCF and (ii) grant a security interest to MCF in the MCF Collateral, and further acknowledges and agrees that such sale and grant of security interest shall not constitute a default or event of default by the Company under the FGI Documents or any related agreement or instrument.

FGI waives, releases and discharges any interest it has or might have in any MCF Purchased Accounts as representative of the proceeds of any of the Company’s inventory or any payments received by FGI on the MCF Purchased Accounts as well as all goods returned under the MCF Purchased Accounts.

4. Priority of Sales of Accounts and Security Interests. MCF and FGI agree that at all times, whether before, after or during the pendency of any bankruptcy, reorganization or other insolvency proceeding with respect to the Company, and notwithstanding the priorities which would ordinarily result from the order of execution or granting of any security interest in the Company’s assets or the order of filing of any financing statements related to MCF Documents or to FGI Documents:

4.1 MCF Primary Collateral. MCF’s security interest in the Company’s Domestic Accounts, proceeds of inventory constituting Company’s Domestic Accounts, general intangibles, contract rights and all relating collateral as it relates to Company’s Domestic Accounts (such property, the “MCF Primary Collateral”) shall be a senior priority security interest, superior to any rights as purchaser of Accounts or the holder of a security interest that FGI receives pursuant to the FGI Factoring Agreement in the MCF Primary Collateral, if any, and FGI’s security interest in MCF Primary Collateral, if any, shall be subordinate and inferior to MCF’s rights as purchaser of Accounts or the holder of a security interest.

4.2 FGI Primary Collateral. FGI’s security interest in all assets of the Company other than the MCF Primary Collateral (such property, the “FGI Primary Collateral”) shall be a senior priority security interest, superior to any rights as purchaser of Accounts or the holder of a security interest that MCF receives pursuant to the MCF Factoring Agreement in the FGI Primary Collateral, if any, and MCF’s security interest in FGI Primary Collateral, if any, shall be subordinate and inferior to FGI’s rights as purchaser of Accounts or the holder of a security interest.

4.3. Non-Avoidance and Subordination. The subordinations and priorities specified in this Section 4 are expressly conditioned upon the validity, perfection and non-avoidance of the security interest to which the other security interest is subordinated, and, if the security interest to which the other security interest is subordinated is or becomes invalid, unperfected or is avoided for any reason, then the subordination and relative priority agreements provided for herein shall not be effective as to that portion of the security interest which is the subject of the unperfected, invalid or avoided security interest.

4.4 Distribution of Proceeds of Collateral. At all times:

4.4.1 Whether prior to or after Company’s default, all proceeds of the MCF Primary Collateral including all Domestic Accounts shall at all times, whether prior to or after Customer’s default, be payable and paid to no one other than MCF in accordance with the terms of the MCF Documents.

4.4.2 Whether prior to or after Company’s default, all proceeds of Non-Domestic Accounts shall be payable and paid to no one other than FGI in accordance with the terms of the FGI Documents.

5. Standby as to Enforcement of Security Interests.

FGI agrees that, without the prior written consent of MCF, it will not ask for, demand, sue for, take, receive, or repossess from the Company, by setoff or in any other manner, the whole or any part of the Domestic Accounts, or foreclose or otherwise realize upon the whole or any part of the MCF Primary Collateral, whether by judicial action or under power of sale, by self-help repossession or otherwise, unless and until all of the obligations, liabilities and indebtedness of the Company to MCF under the MCF Documents have been paid in full and the MCF Documents have been terminated, in writing, by MCF.

5.2 As to FGI’s Primary Collateral. MCF agrees that, without the prior written consent of FGI, it will not ask for, demand, sue for, take, receive, or repossess from the Company, by setoff or in any other manner, the whole or any part of the Non-Domestic Accounts.

6. Remittance of Funds.

6.1 By FGI. Company hereby consents to FGI’s releasing and/or transferring to MCF in its discretion, any sums of money that FGI collects and deems available for distribution upon FGI’s receipt from MCF of any written request for such funds or in the event FGI determines that such sums belong to or should be transferred to MCF. Company agrees to hold FGI harmless in the event it releases or transfers any such funds to MCF.

6.2 By MCF. Company hereby consents to MCF’s releasing and/or transferring to FGI in its discretion, any sums of money that MCF collects and deems available for distribution upon MCF’s receipt from FGI of any written request for such funds or in the event MCF determines that such sums belong to or should be transferred to FGI. Company agrees to hold MCF harmless in the event it releases or transfers any such funds to FGI.

7. Statements of Account. The Company authorizes both FGI and MCF to obtain from each other, upon written request, statements that either MCF or FGI may routinely issue to the Company with respect to the outstanding Accounts, covering transactions under the MCF and FGI Documents.

8. Negative Pledge. Both MCF and FGI agree that, without the prior written consent of either, neither will ask for, accept or receive from the Company any lien in or security interest upon any assets of the Company except as noted and provided in this Agreement and/or in the MCF Factoring Agreement or FGI Factoring Agreement.

10. Certain Required Notices. MCF and FGI hereby agree to give each other, within five (5) calendar days of the giving of written notice to the Company, written notice of any declared defaults in the Company’s obligations under the MCF Documents or FGI Documents, respectively. If either MCF or FGI exercises their option to terminate the MCF Documents or FGI Documents, respectively, upon the occurrence of any declared defaults or any event justifying such termination under the MCF Documents or FGI Documents either party that exercises its option to terminate shall give written notice of such termination to the other within five (5) calendar days of the giving of written notice to the Company.

11.3 The obligations, liabilities and indebtedness of the Company to FGI under the FGI Documents are paid and satisfied in full and the FGI Documents are terminated in writing by FGI.

12. Notices. All notices required or permitted hereunder shall be in writing and shall be made by overnight air courier or certified mail, return receipt requested, and shall be deemed to have been validly given or delivered one (1) business day after sending, if sent by overnight air courier, and three (3) business days after sending, if sent by certified or registered mail, addressed to the party to be notified as follows:

or such other address as any party may designate for itself by like notice.

13. No Waiver. Nothing contained in this Agreement and no act or action taken or done by either MCF or FGI pursuant to the powers and rights granted hereunder or under any document executed in connection herewith shall be deemed to be a waiver by either MCF or FGI of any of its rights and remedies against the Company in connection with, or in respect of, any of the obligations, liabilities and indebtedness of the Company to either MCF or FGI under either the MCF or FGI Documents.

14. Marshalling of Assets. FGI hereby waives any and all rights to have the MCF Collateral, or any part thereof, marshalled upon any foreclosure or other enforcement of MCF’s liens. MCF hereby waives any and all rights to have the FGI Collateral, or any part thereof, marshalled upon any foreclosure or other enforcement of FGI’s liens.

15. Post Bankruptcy Issues. This Agreement shall be applicable both before and after the filing of any petition by or against the Company under any applicable bankruptcy, reorganization or insolvency law and all references herein to the Company shall be deemed to apply to the Company as Debtor-in-Possession and all allocations of payments between MCF and FGI shall, subject to any court order approving the financing of the Company as debtor-in-possession, continue to be made after the filing thereof on the same basis that the payments were to be applied prior to the date of any petition. If MCF shall desire to permit the use of cash collateral or to provide financing to the Company under any applicable bankruptcy, reorganization or insolvency law, FGI agrees that it will not object to any use of such cash collateral or financing on the ground of a failure to provide adequate protection for FGI so long as MCF does not impair any of FGI’s Collateral.

Nothing contained in this Agreement is intended to affect or limit, in any way whatsoever, the security interests that MCF and FGI has in any of the assets of the Company, whether tangible or intangible, insofar as the rights of the Company and third parties are involved. MCF and FGI specifically reserve any and all of their respective rights, security interests and rights to assert security interests as against the Company and any third parties.

18. Severability.
