4.5. Electronic Chattel Paper and Transferable Records. If Debtor at any time holds or acquires an interest in any electronic chattel paper or any “transferable record,” as that term is defined in Section 201 of the federal Electronic Signatures in Global and National Commerce Act (as hereafter amended), or in Section 16 of the Uniform Electronic Transactions Act as in effect in any relevant jurisdiction, Debtor shall promptly notify Secured Party thereof and, at the request and option of Secured Party, shall take such action as Secured Party may reasonably request to vest in Secured Party control, under Section 9-105 of the Uniform Commercial Code, of such electronic chattel paper or control under Section 201 of the federal Electronic Signatures in Global and National Commerce Act or, as the case may be, Section 16 of the Uniform Electronic Transactions Act, as so in effect in such jurisdiction, of such transferable record.

Anything herein to the contrary notwithstanding, Debtor shall remain obligated and liable under each contract or agreement comprised in the Collateral to be observed or performed by Debtor thereunder. Secured Party shall not have any obligation or liability under any such contract or agreement by reason of or arising out of this Agreement or the receipt by Secured Party of any payment relating to any of

8

the Collateral, nor shall Secured Party be obligated in any manner to perform any of the obligations of Debtor under or pursuant to any such contract or agreement, to make inquiry as to the nature or sufficiency of any payment received by Secured Party in respect of the Collateral or as to the sufficiency of any performance by any party under any such contract or agreement, to present or file any claim, to take any action to enforce any performance or to collect the payment of any amounts which may have been assigned to Secured Party or to which Secured Party may be entitled at any time or times. Secured Party’s sole duty with respect to the custody, safe keeping and physical preservation of the Collateral in its possession, under Section 9-207 of the Uniform Commercial Code of the State or otherwise, shall be to deal with such Collateral in the same manner as Secured Party deals with similar property for its own account.

SECTION 12. Securities and Deposits. Secured Party may at any time following and during the continuance of an Event of Default, at its option, transfer to itself or any nominee any securities constituting Collateral, receive any income thereon and hold such income as additional Collateral or apply it to the Obligations. Whether or not any Obligations are due, Secured Party may following and during the continuance of an Event of Default demand, sue for, collect or make any settlement or compromise which it deems desirable with respect to the Collateral. Regardless of the adequacy of Collateral or any other security for the Obligations, any deposits or other sums at any time credited by or due from Secured Party to Debtor may at any time be applied to or set off against any of the Obligations.

SECTION 13. Notification to Account Debtors and Other Persons Obligated on Collateral.

After the making of such a request or the giving of any such notification, Debtor shall hold any proceeds of collection of accounts, chattel paper, general intangibles, instruments and other Collateral received by Debtor as trustee for Secured Party without commingling the same with other funds of Debtor and shall turn the same over to Secured Party in the identical form received, together with any necessary endorsements or assignments. Secured Party shall apply the proceeds of collection of accounts, chattel paper, general intangibles, instruments and other Collateral received by Secured Party to the Obligations, such proceeds to be immediately credited after final payment in cash or other immediately available funds of the items giving rise to them.

SECTION 14. Power of Attorney.

14.1. Appointment and Powers of Secured Party. Debtor hereby irrevocably constitutes and appoints Secured Party and any officer or agent thereof, with full power of substitution, as its true and lawful attorneys-in-fact with full irrevocable power and authority in the place and stead of Debtor or in Secured Party’s own name, for the purpose of carrying out the terms of this Agreement, to take any and all appropriate action and to execute any and all documents and instruments that may be necessary or useful to accomplish the purposes of this Agreement and, without limiting the generality of the foregoing, hereby gives said attorneys the power and right, on behalf of Debtor, without notice to or assent by Debtor, to do the following:

9

14.2. Ratification by Debtor. To the extent permitted by law, Debtor hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof. This power of attorney is a power coupled with an interest and is irrevocable.

14.3. No Duty on Secured Party. The powers conferred on Secured Party hereunder are solely to protect its interests in the Collateral and shall not impose any duty upon it to exercise any such powers. Secured Party shall be accountable only for the amounts that it actually receives as a result of the exercise of such powers, and neither it nor any of its officers, directors, employees or agents shall be responsible to Debtor for any act or failure to act, except for Secured Party’s own gross negligence or willful misconduct.

SECTION 15. Rights and Remedies. If an Event of Default shall have occurred and be continuing, Secured Party, without any other notice to or demand upon Debtor, has in any jurisdiction in which enforcement hereof is sought, in addition to all other rights and remedies, whether conferred in the Credit Agreement or at law or in equity, the rights and remedies of a secured party under the Uniform Commercial Code of the State and any additional rights and remedies which may be provided to a secured party in any jurisdiction in which Collateral is located including, without limitation, the right to take possession of the Collateral, and for that purpose Secured Party may, so far as Debtor can give authority therefor, enter upon any premises on which the Collateral may be situated and remove the same therefrom. Secured Party may in its discretion require Debtor to assemble all or any part of the Collateral at such location or locations within the jurisdiction(s) of Debtor’s principal office(s) or at such other locations as Secured Party may reasonably designate. Unless the Collateral is perishable or threatens to decline speedily in value or is of a type customarily sold on a recognized market, Secured Party shall give to Debtor at least ten (10) days prior written notice of the time and place of any public sale of Collateral or of the time after which any private sale or any other

10

intended disposition is to be made. Debtor hereby acknowledges that ten (10) days prior written notice of such sale or sales shall be reasonable notice. In addition, Debtor waives any and all rights that it may have to a judicial hearing in advance of the enforcement of any of Secured Party’s rights and remedies hereunder including, without limitation, its right following an Event of Default to take immediate possession of the Collateral and to exercise its rights and remedies with respect thereto.

SECTION 16. Standards for Exercising Rights and Remedies. To the extent that applicable law imposes duties on Secured Party to exercise remedies in a commercially reasonable manner, Debtor acknowledges and agrees that it is not commercially unreasonable for Secured Party (a) to fail to incur expenses reasonably deemed significant by Secured Party to prepare Collateral for disposition or otherwise to fail to complete raw material or work in process into finished goods or other finished products for disposition, (b) to fail to obtain third party consents for access to Collateral to be disposed of, or to obtain or, if not required by other law, to fail to obtain governmental or third party consents for the collection or disposition of Collateral to be collected or disposed of, (c) to fail to exercise collection remedies against account debtors or other persons obligated on Collateral or to fail to remove liens or encumbrances on or any adverse claims against Collateral, (d) to exercise collection remedies against account debtors and other persons obligated on Collateral directly or through the use of collection agencies and other collection specialists, (e) to advertise dispositions of Collateral through publications or media of general circulation, whether or not the Collateral is of a specialized nature, (f) to contact other persons, whether or not in the same business as Debtor, for expressions of interest in acquiring all or any portion of the Collateral, (g) to hire one or more professional auctioneers to assist in the disposition of Collateral, whether or not the Collateral is of a specialized nature, (h) to dispose of Collateral by utilizing Internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capability of doing so, or that match buyers and sellers of assets, (i) to dispose of assets in wholesale rather than retail markets, (j) to disclaim disposition warranties, (k) to purchase insurance or credit enhancements to insure Secured Party against risks of loss, collection or disposition of Collateral or to provide to Secured Party a guaranteed return from the collection or disposition of Collateral or (l) to the extent deemed appropriate by Secured Party, to obtain the services of other brokers, investment bankers, consultants and other professionals to assist Secured Party in the collection or disposition of any of the Collateral. Debtor acknowledges that the purpose of this Section 16 is to provide non-exhaustive indications of what actions or omissions by Secured Party would fulfill Secured Party’s duties under the Uniform Commercial Code or other law of the State or any other relevant jurisdiction in Secured Party’s exercise of remedies against the Collateral and that other actions or omissions by Secured Party shall not be deemed to fail to fulfill such duties solely on account of not being indicated in this Section 16. Without limitation upon the foregoing, nothing contained in this Section 16 shall be construed to grant any rights to Debtor or to impose any duties on Secured Party that would not have been granted or imposed by this Agreement or by applicable law in the absence of this Section 16.

SECTION 17. No Waiver by Secured Party, Etc. Secured Party shall not be deemed to have waived any of its rights or remedies in respect of the Obligations or the Collateral unless such waiver shall be in writing and signed by Secured Party. No delay or omission on the part of Secured Party in exercising any right or remedy shall operate as a waiver of such right or remedy or any other right or remedy. A waiver on any one occasion shall not be construed as a bar to or waiver of any right or remedy on any future occasion.

SECTION 18. Suretyship Waivers by Debtor. Debtor waives demand, notice, protest, notice of acceptance of this Agreement, notice of loans made, credit extended, Collateral received or delivered or other action taken in reliance hereon and all other demands and notices of any description. With respect to both the Obligations and the Collateral, Debtor assents to any extension or postponement of the time of payment or any other indulgence, to any substitution, exchange or release of or failure to perfect any security interest in any Collateral, to the addition or release of any party or person primarily or secondarily liable, to the acceptance of partial payment thereon and the settlement, compromising or adjusting of any thereof, all in such manner and at such time or times as Secured Party may deem advisable. Secured Party shall have no duty as to the collection or protection of the Collateral or any income therefrom, the preservation of rights against prior parties, or the preservation of any rights pertaining thereto beyond the safe custody thereof as set forth in Section 11.2. Debtor further waives any and all other suretyship defenses.

SECTION 19. Marshalling. Secured Party shall not be required to marshal any present or future collateral security (including but not limited to the Collateral) for, or other assurances of payment of, the Obligations or any of them or to resort to such collateral security or other assurances of payment in any particular order, and all of its rights and remedies hereunder and in respect of such collateral security and other assurances of payment shall be cumulative and in addition to all other rights and remedies, however existing or arising. To the extent that it lawfully may, Debtor hereby agrees that it will not invoke any law relating to the marshalling of collateral which might cause delay in or impede the enforcement of Secured Party’s rights and remedies under this Agreement or under any other instrument creating or evidencing any of the Obligations or under which any of the Obligations are outstanding or by which any of the Obligations are secured or payment thereof is otherwise assured, and, to the extent that it lawfully may, Debtor hereby irrevocably waives the benefits of all such laws.

SECTION 20. Proceeds of Dispositions; Expenses. Debtor shall pay to Secured Party on demand any and all expenses, including reasonable attorneys’ fees and disbursements, incurred or paid by Secured Party in protecting, preserving or enforcing Secured Party’s rights and remedies under or in respect of any of the Obligations or any of the Collateral. After deducting all of said expenses, the residue of any proceeds of collection or sale or other disposition of the Collateral shall, to the extent actually received in cash, be applied to the payment of the Obligations in such order or preference as Secured Party may determine, proper allowance and provision being made for any Obligations not then due. Upon the final payment and satisfaction in full of all of the Obligations and after making any payments required by Sections 9-608(a)(1)(C) or 9-615(a)(3) of the Uniform Commercial Code of the State, any excess shall be returned to Debtor. In the absence of final payment and satisfaction in full of all of the Obligations, Debtor shall remain liable for any deficiency.

SECTION 21. Overdue Amounts. Until paid, all amounts due and payable by Debtor hereunder shall be a debt secured by the Collateral and shall bear, whether before or after judgment, interest at the Default Rate.

SECTION 22. Governing Law; Consent to Jurisdiction. THIS AGREEMENT IS INTENDED TO TAKE EFFECT AS A SEALED INSTRUMENT AND SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEBRASKA. Debtor agrees that any action or claim arising out of, or any dispute in connection with, this Agreement, any rights, remedies, obligations, or duties hereunder, or the performance or enforcement hereof or thereof, may be brought in the courts of any federal court sitting therein and consents to the non-exclusive jurisdiction of such court and to service of process in any such suit being made upon Debtor by mail at the address specified in the notice provision of the Credit Agreement. Debtor hereby waives any objection that it may now or hereafter have to the venue of any such suit or any such court or that such suit is brought in an inconvenient court.

SECTION 23. Waiver of Jury Trial. DEBTOR WAIVES ITS RIGHT TO A JURY TRIAL WITH RESPECT TO ANY ACTION OR CLAIM ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THIS AGREEMENT, ANY RIGHTS, REMEDIES, OBLIGATIONS OR DUTIES HEREUNDER, OR THE PERFORMANCE OR ENFORCEMENT HEREOF OR THEREOF. Except as prohibited by law, Debtor waives any right which it may have to claim or recover in any litigation referred to in the preceding sentence any special, exemplary, punitive or consequential damages or any damages other than, or in addition to, actual damages. Debtor (a) certifies that neither Secured Party nor any representative, agent or attorney of Secured Party has represented, expressly or otherwise, that Secured Party would not, in the event of litigation, seek to enforce the foregoing waivers or other waivers contained in this Agreement and (b) acknowledges that, in entering into the Credit Agreement and the other Loan Documents to which Secured Party is a party, Secured Party is relying upon, among other things, the waivers and certifications contained in this Section 23.

SECTION 24. Miscellaneous. The headings of each section of this Agreement are for convenience only and shall not define or limit the provisions thereof. This Agreement and all rights and obligations hereunder shall be binding upon Debtor and its respective successors and assigns, and shall inure to the benefit of Secured Party and its successors and assigns. If any term of this Agreement shall be held to be invalid, illegal or unenforceable, the validity of all other terms hereof shall in no way be affected thereby, and this Agreement shall be construed and be enforceable as if such invalid, illegal or unenforceable term had not been included herein. Debtor acknowledges receipt of a copy of this Agreement. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original.
