6. DEFAULT.

(b) If any one or more of the Events of Default shall occur, all or any part of any Obligations not payable on demand shall, at the election of the Secured Party, become and be due and payable at once, without presentment, demand, protest or further notice of any kind. The provisions of this subparagraph are not intended in any way to and do not affect any rights of the Secured Party with respect to any Obligations which may now or hereafter be payable on demand.

(c) The Secured Party’s rights and remedies with respect to the Collateral shall be those of a Secured Party under the Uniform Commercial Code and under any other applicable law, as the same may from time to time be in effect, in addition to those rights and remedies granted herein and in any other document, instrument or agreement now or hereafter in effect between the Debtor and the Secured Party. If any one or more of the Events of Default shall occur, the Secured Party may require the Debtor to assemble the Collateral and make it available to the Secured Party at a place or places designated by the Secured Party, and the Secured Party may use and operate the Collateral, and, in this regard, the Secured Party shall be entitled as a matter of right, if it shall so elect, forthwith, without prior demand or notice, and without declaring any of the Obligations to be due and payable, and without regard to the value of the Collateral or any part thereof, to the appointment of a receiver or receivers of the Collateral or any part thereof, and of all revenues and profits thereof, in order to manage, protect and preserve the Collateral or any part thereof and to continue the operations and business of the Debtor, with such powers as the court making such appointment shall confer, which may comprise any or all of the powers that the Secured Party is authorized to exercise hereunder or under applicable law.

(d) Without in any way requiring notice to be given in the following time and manner, the Debtor agrees that any notice by the Secured Party of sale, disposition or other intended action hereunder or in connection herewith, whether required by the Uniform Commercial Code or otherwise, shall constitute reasonable notice to the Debtor if such notice is mailed by regular or certified mail, postage prepaid, at least five (5) days prior to such action to the Debtor’s address specified below or to any other address which the Debtor has specified in writing to the Secured Party as the address to which notices hereunder shall be given to the Debtor.

(e) The Debtor agrees to pay on demand all costs and expenses incurred by the Secured Party in enforcing this Security Agreement, in realizing upon or protecting any Collateral and in enforcing and collecting any Obligations or any guaranty thereof, including, without limitation, if the Secured Party retains counsel for advice, suit, appeal, insolvency or other proceedings under the federal Bankruptcy Code or otherwise, or for any of the above purposes, the actual attorneys’ fees incurred by the Secured Party. Payment of all moneys hereunder is secured by the Collateral.

8. MISCELLANEOUS

(a) The Debtor hereby authorizes the Secured Party, at the Debtor’s expense, to file such financing statement or statements relating to the Collateral without the Debtor’s signature thereon as the Secured Party at its option may deem appropriate, and appoints the Secured Party as the Debtor’s attorney-in-fact (without requiring the Secured Party) to execute any such financing statement or statements in the Debtor’s name and to perform all other acts which the Secured Party deems appropriate to perfect and continue the Security Interest and to protect, preserve and realize upon the Collateral. This power of attorney shall be not affected by the subsequent disability or incompetence of the Debtor.

(b) Without limiting any other right of the Secured Party, whenever the Secured Party has the right to declare any Obligations to be immediately due and payable (whether or not it has so declared), the Secured Party at its sole election may set off against the Obligations any and all moneys then or thereafter owed to the Debtor by the Secured Party in any capacity, whether or not the Obligations or the obligation to pay such moneys owed by the Secured Party is then due, and the Secured Party shall be deemed to have exercised such right

- 2 -

of set off immediately at the time of such election even though any charge therefore is made or entered on the Secured Party’s records subsequent thereto.

(c) Upon the Debtor’s failure to perform any of its duties hereunder, the Secured Party may, but shall not be obligated to, perform any or all such duties, including without limitation, payment of taxes, assessments, insurance and other charges and expenses as herein provided, and the Debtor shall pay an amount equal to the cost thereof to the Secured Party on demand by the Secured Party. Payment of all moneys hereunder is secured by the Collateral.

(e) No course of dealing between the Debtor and the Secured Party and no delay or omission by the Secured Party in exercising any right or remedy hereunder or with respect to any Obligations shall operate as a waiver thereof or of any other right or remedy, and no single or partial exercise thereof shall preclude any other or further exercise thereof or the exercise of any other right or remedy. The Secured Party may remedy any default by the Debtor hereunder or with respect to any Obligations in any reasonable manner without waiving the default remedied and without waiving any other prior or subsequent default by the Debtor. All rights and remedies of the Secured Party hereunder are cumulative.

(f) The Debtor authorizes the Secured Party, without notice or demand and without affecting the Debtor’s obligations hereunder, from time to time: (i) to exchange, enforce or release any collateral or any part thereof (other than the Collateral) taken from any party for payment of the Obligations or any part thereof; (ii) to release, substitute or modify any obligation of any Third Party Obligor; (iii) if any one or more of the Events of Default shall occur, to direct the order or manner of disposition of the Collateral and any and all other collateral and the enforcement of any and all endorsements, guaranties and other obligations relating to the Obligations or any part thereof, as the Secured Party, in its sole and absolute discretion, may determine; and (iv) to determine how, when and what application of payments and credits, if any, shall be made on the Obligations or any part thereof.

(h) The rights and benefits of the Secured Party hereunder shall, if the Secured Party so directs, inure to any party acquiring any interest in the Obligations or any part thereof.

(i) This Security Agreement shall be binding upon the Debtor, its legal representatives, successors and assigns, and shall inure to the benefit of the Secured Party, its legal representatives, successors and assigns.

(j) In the event that more than one Debtor shall execute this Security Agreement, the term “Debtor” shall include each as well as all of them, and all obligations, agreements, representations, warranties and covenants hereunder shall be their joint and several obligations, agreements, representations, warranties and covenants. Wherever used herein, words of singular neuter import shall be read as if written in the plural, masculine or feminine whenever the circumstances so require.

(k) No recision, waiver, release, modification or amendment of any provision of this Security Agreement shall be valid unless the same shall be in writing and signed by a duly authorized officer of the Secured Party.

(l) The validity, interpretation and legal effect of this Security Agreement shall be governed by, and all rights and liabilities hereunder shall be determined in accordance with the laws of the State of New York. THE DEBTOR HEREBY AGREES THAT ANY ACTION OR PROCEEDING TO ENFORCE OR ARISING OUT OF THIS SECURITY AGREEMENT MAY BE COMMENCED, AT THE OPTION OF THE SECURED PARTY, IN COURTS HAVING SUITS WITHIN THE STATE OF NEW YORK AND THE DEBTOR HEREBY CONSENTS TO THE JURISDICTION OF ANY LOCAL, STATE OR FEDERAL COURT SELECTED BY THE SECURED PARTY WHICH IS LOCATED WITHIN THE STATE OF NEW YORK AND AGREES NOT TO DISTURB SUCH CHOICE OF FORUM BY THE SECURED PARTY. THE DEBTOR HEREBY WAIVES PERSONAL SERVICE OF PROCESS AND AGREES THAT ANY SUMMONS AND COMPLAINT OR OTHER PROCESS COMMENCING AN ACTION OR PROCEEDING IN ANY SUCH COURT SHALL BE PROPERLY SERVED AND SHALL CONFER PERSONAL JURISDICTION (I) IF SERVED BY REGISTERED OR CERTIFIED MAIL TO THE DEBTOR AT THE ADDRESS OF THE DEBTOR STATED BELOW OR SUCH OTHER ADDRESS AS THE DEBTOR MAY FROM TIME TO TIME SPECIFY IN A WRITTEN NOTICE COMPLYING AS TO DELIVERY WITH THE TERMS OF THE IMMEDIATELY SUCCEEDING SUBPARAGRAPH OF THIS PARAGRAPH, OR (II) IF SERVED AS OTHERWISE PROVIDED BY THE LAWS OF THE STATE OF NEW YORK OR THE LAWS OF THE UNITED STATES OF AMERICA. THE DEBTOR HEREBY WAIVES (I) TRIAL BY JURY IN ANY SUCH ACTION OR PROCEEDING TO ENFORCE OR ARISING OUT OF THIS SECURITY AGREEMENT, AND (II) THE RIGHT TO INTERPOSE ANY COUNTERCLAIM OR SET-OFF OF ANY KIND OR DESCRIPTION IN ANY SUCH ACTION OR PROCEEDING.

(m) All notices, requests, demands, directions and other communications which may or are required to be given, served or sent by either the Secured Party or the Debtor to the other under this Security Agreement shall be in writing and shall be deemed to have been properly given or sent if mailed by registered or certified mail with postage prepaid, addressed to the applicable party (i) in the case of the Secured Party, at 1759 Wehrle Drive, Williamsville, New York 14221 (Attention: Vice President—Credit), (ii) in the case of the Debtor, at the address of the Debtor stated below, or (iii) in the case of each party, at such other address as shall be designated by such party in a written notice to the other party complying as to delivery with the terms of this subparagraph. All such notices, requests, demands, directions and other communications shall, when mailed in the aforesaid manner, be effective when so mailed, except as otherwise provided herein.

(n) All terms, unless otherwise defined in this Security Agreement, shall have the definitions set forth in the Uniform Commercial Code from time to time in effect in the State of New York.

(o) The Debtor hereby irrevocably appoints the Secured Party the Debtor’s agent with full power, in the same manner, to the same extent and with the same effect as if the Debtor were to do the same: to receive and collect all mail addressed to the Debtor; to direct the place of delivery thereof to any location designated by the Secured Party; to open such mail; to remove all contents therefrom; to retain all contents thereof constituting or relating to the Collateral; and to perform all other acts which the Secured Party deems appropriate to protect, preserve and realize upon the Collateral. The agency hereby created is unconditional and shall not terminate until all of the Obligations are finally and irrevocably paid in full and until all commitments by the Secured Party to extend credit to the Debtor have expired or been terminated. This power of attorney shall not be affected by the subsequent disability or incompetence of the Debtor.

(p) This Security Agreement shall not be deemed or construed to create any commitment or other obligation on the part of the Secured Party to make any sales or deliveries of Equipment or Inventory to the Debtor and all sales and

- 3 -

deliveries to be made, if any, shall be made from time to time at the sole discretion of the Secured Party upon such terms and conditions as the Secured Party shall determine from time to time in the Secured Party’s sole judgment and discretion.

(q) This Security Agreement is and is intended to be a continuing Security Agreement and shall remain in full force and effect until ten (10) days after the Secured Party shall have actually received from the Debtor written notice of its discontinuance; provided, however, that this Security Agreement shall remain in full force and effect thereafter until all of the Obligations outstanding, or contracted or committed for (whether or not outstanding), before the receipt of such notice by the Secured Party and the expiration of such ten (10) day period, and any extensions or renewals thereof (whether made before or after receipt of such notice or before or after the expiration of such ten (10) day period), together with interest accruing thereon, shall be finally and irrevocably paid in full. If after receipt of any payment of all or any part of the Obligations, the Secured Party is for any reason compelled to surrender such payment to any party, because such payment is determined to be void or voidable as a preference, impermissible set off, or a diversion of trust funds, or for any other reason, this Security Agreement shall continue in full force and effect notwithstanding any contrary action which may have been taken by the Secured Party in reliance upon such payment, and any such contrary action so taken shall be without prejudice to the Secured Party’s rights under this Security Agreement and shall be deemed to have been conditioned upon such payment having become final and irrevocable.

IN WITNESS WHEREOF, the Debtor and the Secured Party have duly executed this Security Agreement effective as of the 3^rd day of March, 2004.
