2. Security Interest. As security for the Indebtedness, Debtor, for value received, hereby pledges and grants to Secured Party a continuing security interest in the Collateral.

3. Representations and Warranties. In addition to any representations and warranties of Debtor set forth in the Loan Documents, which are incorporated herein by this reference, Debtor hereby represents and warrants the following to Secured Party:

(a) Authority. The execution, delivery and performance of this Agreement and all of the other Loan Documents by Debtor have been duly authorized by all necessary corporate action of Debtor, to the extent Debtor is a corporation, by all necessary partnership action, to the extent Debtor is a partnership, or by all necessary limited liability company action, to the extent Debtor is a limited liability company.

(b) Accuracy of Information. All information heretofore, herein or hereafter supplied to Secured Party by or on behalf of Debtor with respect to the Collateral is true and correct. The exact legal name, social security number (if applicable), tax identification number, employee identification number and organization number of Debtor is correctly shown in the first paragraph hereof.

(c) Enforceability. This Agreement and the other Loan Documents constitute legal, valid and binding obligations of Debtor, enforceable in accordance with their respective terms, except as limited by bankruptcy, insolvency or similar laws of general application relating to the enforcement of creditors’ rights and except to the extent specific remedies may generally be limited by equitable principles.

(d) Ownership and Liens. Debtor has good and marketable title to the Collateral free and clear of all liens, security interests, encumbrances or adverse claims, except for the security interest created by this Agreement. No dispute, right of setoff, counterclaim or defense exists with respect to all or any part of the Collateral. Debtor has not executed any other security agreement currently affecting the Collateral and no effective financing statement or other instrument similar in effect covering all or any part of the Collateral is on file in any recording office except as may have been executed or filed in favor of Secured Party.

(e) No Conflicts or Consents. Neither the ownership, the intended use of the Collateral by Debtor, the grant of the security interest by Debtor to Secured Party herein nor the exercise by Secured Party of its rights or remedies hereunder, will (i) conflict with any provision of (A) any domestic or foreign law, statute, rule or regulation, (B) the articles or certificate of incorporation, charter, bylaws, partnership agreement, articles or certificate of organization, or regulations as the case may be, of Debtor, or (C) any agreement, judgment, license, order or permit applicable to or binding upon Debtor, or (ii) result in or require the creation of any lien, charge or encumbrance upon any assets or properties of Debtor or of any person except as may be expressly contemplated in the Loan Documents. Except as expressly contemplated in the Loan Documents, no consent, approval, authorization or order of, and no notice to or filing with, any court, governmental authority or third party is required in connection with the grant by Debtor of the security interest herein or the exercise by Secured Party of its rights and remedies hereunder.

(f) Security Interest. Debtor has and will have at all times full right, power and authority to grant a security interest in the Collateral to Secured Party in the manner provided herein, free and clear of any lien, security interest or other charge or encumbrance. This Agreement creates a legal, valid and binding security interest in favor of Secured Party in the Collateral securing the Indebtedness. To the extent permitted in the Code, possession by Secured Party of all certificates, instruments and cash constituting Collateral from time to time and/or the filing of the financing statements delivered prior hereto and/or concurrently herewith by Debtor to Secured Party will perfect and establish the first priority of Secured Party’s security interest hereunder in the Collateral.

(g) Location/Identity. Debtor’s principal place of business and chief executive office (as those terms are used in the Code), as the case may be is located at the address set forth on the first page hereof. Except as specified elsewhere herein, all Collateral and records concerning the Collateral shall be kept at such address. Debtor’s organizational structure, state of organization, and organizational number (the “Organizational Information”) are as set forth on the first page hereof. Except as specified herein, the Organizational Information shall not change.

(h) Solvency of Debtor. As of the date hereof, and after giving effect to this Agreement and the completion of all other transactions contemplated by Debtor at the time of the execution of this Agreement, (i) Debtor is and will be solvent, (ii) the fair saleable value of Debtor’s assets exceeds and will continue to exceed Debtor’s liabilities (both fixed and contingent), (iii) Debtor is paying and will continue to be able to pay its debts as they mature, and (iv) if Debtor is not an individual, Debtor has and will have sufficient capital to carry on Debtor’s businesses and all businesses in which Debtor is about to engage.

(i) Exclusion of Certain Collateral. Unless otherwise agreed by Secured Party, the Collateral does not include any aircraft, watercraft or vessels, railroad cars, railroad equipment, locomotives or other rolling stock intended for a use related to interstate commerce.

(j) Inventory. The security interest in the inventory shall continue through all stages of manufacture and shall, without further action, attach to the accounts or other proceeds resulting from the sale or other disposition thereof and to all such inventory as may be returned to Debtor by its account debtors.

(k) Accounts. Each account represents the valid and legally binding indebtedness of a bona fide account debtor arising from the sale or lease by Debtor of goods or the rendition by Debtor of services and is not subject to contra accounts, setoffs, defenses or counterclaims by or available to account debtors obligated on the accounts except as disclosed by Debtor to Secured Party from time to time in writing. The amount shown as to each account on Debtor’s books is the true and undisputed amount owing and unpaid thereon, subject only to discounts, allowances, rebates, credits and adjustments to which the account debtor has a right and which have been disclosed to Secured Party in writing.

(l) Chattel Paper, Documents and Instruments. The chattel paper, documents and instruments of Debtor pledged hereunder have only one original counterpart and no party other than Debtor or Secured Party is in actual or constructive possession of any such chattel paper, documents or instruments.

4. Affirmative Covenants. In addition to all covenants and agreements of Debtor set forth in the Loan Documents, which are incorporated herein by this reference, Debtor will comply with the covenants contained in this Section 4 at all times during the period of time this Agreement is effective unless Secured Party shall otherwise consent in writing.

(a) Ownership and Liens. Debtor will maintain good and marketable title to all Collateral free and clear of all liens, security interests, encumbrances or adverse claims, except for the security interest created by this Agreement and the security interests and other encumbrances expressly permitted herein or by the other Loan Documents. Debtor will not permit any dispute, right of setoff, counterclaim or defense to exist with respect to all or any part of the Collateral. Debtor will cause any financing statement or other security instrument with respect to the Collateral to be terminated, except as may exist or as may have been filed in favor of Secured Party. Debtor hereby irrevocably appoints Secured Party as Debtor’s attorney-in-fact, such power of attorney being coupled with an interest, with full authority in the place and stead of Debtor and in the name of Debtor or otherwise, for the purpose of terminating any financing statements currently filed with respect to the Collateral. Debtor will defend at its expense Secured Party’s right, title and security interest in and to the Collateral against the claims of any third party.

(b) Further Assurances. Debtor will from time to time at its expense promptly execute and deliver all further instruments and documents and take all

further action necessary or appropriate or that Secured Party may request in order (i) to perfect and protect the security interest created or purported to be created hereby and the first priority of such security interest, (ii) to enable Secured Party to exercise and enforce its rights and remedies hereunder in respect of the Collateral, and (iii) to otherwise effect the purposes of this Agreement, including without limitation: (A) executing (if requested) and filing such financing or continuation statements, or amendments thereto; and (B) furnishing to Secured Party from time to time statements and schedules further identifying and describing the Collateral and such other reports in connection with the Collateral, all in reasonable detail satisfactory to Secured Party.

(c) Inspection of Collateral. Debtor will keep adequate records concerning the Collateral and will permit Secured Party and all representatives and agents appointed by Secured Party to inspect any of the Collateral and the books and records of or relating to the Collateral at any time during normal business hours, to make and take away photocopies, photographs and printouts thereof and to write down and record any such information.

(d) Payment of Taxes. Debtor (i) will timely pay all property and other taxes, assessments and governmental charges or levies imposed upon the Collateral or any part thereof, (ii) will timely pay all lawful claims which, if unpaid, might become a lien or charge upon the Collateral or any part thereof, and (iii) will maintain appropriate accruals and reserves for all such liabilities in a timely fashion in accordance with generally accepted accounting principles. Debtor may, however, delay paying or discharging any such taxes, assessments, charges, claims or liabilities so long as the validity thereof is contested in good faith by proper proceedings and provided Debtor has set aside on Debtor’s books adequate reserves therefor; provided, however, Debtor understands and agrees that in the event of any such delay in payment or discharge and upon Secured Party’s written request, Debtor will establish with Secured Party an escrow acceptable to Secured Party adequate to cover the payment of such taxes, assessments and governmental charges with interest, costs and penalties and a reasonable additional sum to cover possible costs, interest and penalties (which escrow shall be returned to Debtor upon payment of such taxes, assessments, governmental charges, interests, costs and penalties or disbursed in accordance with the resolution of the contest to the claimant) or furnish Secured Party with an indemnity bond secured by a deposit in cash or other security acceptable to Secured Party. Notwithstanding any other provision contained in this Subsection, Secured Party may at its discretion exercise its rights under Subsection 6(c) at any time to pay such taxes, assessments, governmental charges, interest, costs and penalties.

(e) Mortgagee’s and Landlord’s Waivers. Debtor shall cause each mortgagee of real property owned by Debtor and each landlord of real property leased by Debtor to execute and deliver agreements satisfactory in form and substance to Secured Party by which such mortgagee or landlord waives or subordinates any rights it may have in the Collateral.

(f) Control Agreements. Debtor will cooperate with Secured Party in obtaining a control agreement in form and substance satisfactory to Secured Party with respect to Collateral consisting of:

(g) Insurance. Debtor will, at its own expense, maintain insurance with respect to all Collateral which constitutes goods in such amounts, against such risks, in such form and with such insurers, as shall be satisfactory to Secured Party from time to time. If requested by Secured Party, each policy for property damage insurance shall provide for all losses to be paid directly to Secured Party. If requested by Secured Party, each policy of insurance maintained by Debtor shall (i) name Debtor and Secured Party as insured parties thereunder (without any representation or warranty by or obligation upon Secured Party) as their interests may appear, (ii) contain the agreement by the insurer that any loss thereunder shall be payable to Secured Party notwithstanding any action, inaction or breach of representation or warranty by Debtor, (iii) provide that there shall be no recourse against Secured Party for payment of premiums or other amounts with respect thereto, and (iv) provide that at least thirty (30) days prior written notice of cancellation or of lapse shall be given to Secured Party by the insurer. Debtor will, if requested by Secured Party, deliver to Secured Party original or duplicate policies of such insurance and, as often as Secured Party may reasonably request, a report of a reputable insurance broker with respect to such insurance. Debtor will also, at the request of Secured Party, duly execute and deliver instruments of assignment of such insurance policies and cause the respective insurers to acknowledge notice of such assignment. All insurance payments in respect of loss of or damage to any Collateral shall be paid to Secured Party and applied as Secured Party in its sole discretion deems appropriate.

(h) Accounts and General Intangibles. Debtor will, except as otherwise provided in Subsection 6(e), collect, at Debtor’s own expense, all amounts due or to become due under each of the accounts and general intangibles. In connection with such collections, Debtor may and, at Secured Party’s direction, will take such action not otherwise forbidden by Subsection 5(e) as Debtor or Secured Party may deem necessary or advisable to enforce collection or performance of each of the accounts and general intangibles. Debtor will also duly perform and cause to be performed all of its obligations with respect to the goods or services, the sale or lease or rendition of which gave rise or will give rise to each account and all of its obligations to be performed under or with respect to the general intangibles. Debtor also covenants and agrees to take any action and/or execute any documents that Secured Party may request in order to comply with the Federal Assignment of Claims Act, as amended.

(i) Chattel Paper, Documents and Instruments. Debtor will take such action as may be requested by Secured Party in order to cause any chattel paper, documents or instruments to be valid and enforceable and will cause all chattel paper to have only one original counterpart. Upon request by Secured Party, Debtor will deliver to Secured Party all originals of chattel paper, documents or instruments and will mark all chattel paper with a legend indicating that such chattel paper is subject to the security interest granted hereunder.

5. Negative Covenants. Debtor will comply with the covenants contained in this Section 5 at all times during the period of time this Agreement is effective, unless Secured Party shall otherwise consent in writing.

(a) Transfer or Encumbrance. Debtor will not (i) sell, assign (by operation of law or otherwise), transfer, exchange, lease or otherwise dispose of any of the Collateral, (ii) grant a lien or security interest in or execute, authorize, file or record any financing statement or other security instrument with respect to the Collateral to any party other than Secured Party, or (iii) deliver actual or constructive possession of any of the Collateral to any party other than Secured Party, except for (A) sales and leases of inventory in the ordinary course of business, and (B) the sale or other disposal of any item of equipment which is worn out or obsolete and which has been replaced by an item of equal suitability and value, owned by Debtor and made subject to the security interest under this Agreement, but which is otherwise free and clear of any lien, security interest, encumbrance or adverse claim; provided, however, the exceptions permitted in clauses (A) and (B) above shall automatically terminate upon the occurrence of an Event of Default.

(b) Impairment of Security Interest. Debtor will not take or fail to take any action which would in any manner impair the value or enforceability of Secured Party’s security interest in any Collateral.

(c) Possession of Collateral. Debtor will not cause or permit the removal of any Collateral from its possession, control and risk of loss, nor will Debtor cause or permit the removal of any Collateral (or records concerning the Collateral) from the address on the first page hereof other than (i) as permitted by Subsection 5(a), or (ii) in connection with the possession of any Collateral by Secured Party or by its bailee. If any Collateral is in the possession of a third party, Debtor will join with Secured Party in notifying the third party of Secured Party’s security interest therein and obtaining an acknowledgment from the third party that it is holding the Collateral for the benefit of Secured Party.

(d) Goods. Debtor will not permit any Collateral which constitutes goods to at any time (i) be covered by any document except documents in the possession of the Secured Party, (ii) become so related to, attached to or used in

connection with any particular real property so as to become a fixture upon such real property, or (iii) be installed in or affixed to other goods so as to become an accession to such other goods unless such other goods are subject to a perfected first priority security interest under this Agreement.

(e) Compromise of Collateral. Debtor will not adjust, settle, compromise, amend or modify any Collateral, except an adjustment, settlement, compromise, amendment or modification in good faith and in the ordinary course of business; provided, however, this exception shall automatically terminate upon the occurrence of an Event of Default or upon Secured Party’s written request. Debtor shall provide to Secured Party such information concerning (i) any adjustment, settlement, compromise, amendment or modification of any Collateral, and (ii) any claim asserted by any account debtor for credit, allowance, adjustment, dispute, setoff or counterclaim, as Secured Party may request from time to time.

(f) Financing Statement Filings. Debtor recognizes that financing statements pertaining to the Collateral have been or may be filed in one or more of the following jurisdictions: the jurisdiction of Debtor’s organization, or other such place as the Debtor may be “located” under the provisions of the Code; where Debtor maintains any Collateral, or has its records concerning any Collateral, as the case may be. Without limitation of any other covenant herein, Debtor will neither cause or permit any change in the location of (i) any Collateral, (ii) any records concerning any Collateral, or (iii) the jurisdiction of Debtor’s organization, to a jurisdiction other than as represented in Subsection 3(g), nor will Debtor change its name or the Organizational Information as represented in Subsection 3(g), unless Debtor shall have notified Secured Party in writing of such change at least thirty (30) days prior to the effective date of such change, and shall have first taken all action required by Secured Party for the purpose of further perfecting or protecting the security interest in favor of Secured Party in the Collateral. In any written notice furnished pursuant to this Subsection, Debtor will expressly state that the notice is required by this Agreement and contains facts that may require additional filings of financing statements or other notices for the purpose of continuing perfection of Secured Party’s security interest in the Collateral. Without limiting Secured Party’s rights hereunder, Debtor authorizes Secured Party to file financing statements and amendments thereto under the provisions of the Code as amended from time to time.

(g) Marking of Chattel Paper. Debtor will not create any Chattel Paper without placing a legend on the Chattel Paper acceptable to Secured Party indicating that Secured Party has a security interest in the Chattel Paper.

6. Rights of Secured Party. Secured Party shall have the rights contained in this Section 6 at all times during the period of time this Agreement is effective.

(a) Additional Financing Statements Filings. Debtor hereby authorizes Secured Party to file, without the signature of Debtor, one or more financing or continuation statements, and amendments thereto, relating to the Collateral. Debtor further agrees that a carbon, photographic or other reproduction of this Security Agreement or any financing statement describing any Collateral is sufficient as a financing statement and may be filed in any jurisdiction Secured Party may deem appropriate.

(b) Power of Attorney. Debtor hereby irrevocably appoints Secured Party as Debtor’s attorney-in-fact, such power of attorney being coupled with an interest, with full authority in the place and stead of Debtor and in the name of Debtor or otherwise, after the occurrence of an Event of Default, to take any action and to execute any instrument which Secured Party may deem necessary or appropriate to accomplish the purposes of this Agreement, including without limitation: (i) to obtain and adjust insurance required by Secured Party hereunder; (ii) to demand, collect, sue for, recover, compound, receive and give acquittance and receipts for moneys due and to become due under or in respect of the Collateral; (iii) to receive, endorse and collect any drafts or other instruments, documents and chattel paper in connection with clause (i) or (ii) above; and (iv) to file any claims or take any action or institute any proceedings which Secured Party may deem necessary or appropriate for the collection and/or preservation of the Collateral or otherwise to enforce the rights of Secured Party with respect to the Collateral.

(c) Performance by Secured Party. If Debtor fails to perform any agreement or obligation provided herein, Secured Party may itself perform, or cause performance of, such agreement or obligation, and the expenses of Secured Party incurred in connection therewith shall be a part of the Indebtedness, secured by the Collateral and payable by Debtor on demand.

(d) Debtor’s Receipt of Proceeds. All amounts and proceeds (including instruments and writings) received by Debtor in respect of such accounts or general intangibles shall be received in trust for the benefit of Secured Party hereunder and, upon request of Secured Party, shall be segregated from other property of Debtor and shall be forthwith delivered to Secured Party in the same form as so received (with any necessary endorsement) and applied to the Indebtedness in such manner as Secured Party deems appropriate in its sole discretion.

(e) Notification of Account Debtors. Secured Party may at its discretion from time to time notify any or all obligors under any accounts or general intangibles (i) of Secured Party’s security interest in such accounts or general intangibles and direct such obligors to make payment of all amounts due or to become due to Debtor thereunder directly to Secured Party, and (ii) to verify the accounts or general intangibles with such obligors. Secured Party shall have the right, at the expense of Debtor, to enforce collection of any such accounts or general intangibles and to adjust, settle or compromise the amount or payment thereof, in the same manner and to the same extent as Debtor.

7. Events of Default. Each of the following constitutes an “Event of Default” under this Agreement:

(a) Event of Default. The occurrence of an “Event of Default” as defined in the Second Amended and Restated Loan Agreement of even date herewith between Obligor and Secured Party, as from time to time amended, modified or restated;

(b) Abandonment. Debtor abandons the Collateral or any portion thereof;

(c) Action by Other Lienholder. The holder of any lien or security interest on any of the assets of Debtor, including without limitation, the Collateral (without hereby implying the consent of Secured Party to the existence or creation of any such lien or security interest on the Collateral), declares a default thereunder or institutes foreclosure or other proceedings for the enforcement of its remedies thereunder;

(d) Liquidation, Death and Related Events. If Obligor or any Obligated Party is an entity, the liquidation, dissolution, merger or consolidation of any such entity or, if Obligor or any Obligated Party is an individual, the death or legal incapacity of any such individual; or

(e) Search Report. Secured Party shall receive at any time following the execution of this Agreement a search report indicating that Secured Party’s security interest is not prior to all other security interests or other interests reflected in the report.

8. Remedies and Related Rights. If an Event of Default shall have occurred, and without limiting any other rights and remedies provided herein, under any of the other Loan Documents or otherwise available to Secured Party, Secured Party may exercise one or more of the rights and remedies provided in this Section.

(a) Remedies. Secured Party may from time to time at its discretion, without limitation and without notice except as expressly provided in any of the Loan Documents:

In the event Secured Party shall elect to sell the Collateral, Secured Party may sell the Collateral without giving any warranties as and shall be permitted to specifically disclaim any warranties of title or the like. Further, if Secured Party sells any of the Collateral on credit, Debtor will be credited only with payments actually made by the purchaser, received by Secured Party and applied to the Indebtedness. In the event the purchaser fails to pay for the Collateral, Secured Party may resell the Collateral and Debtor shall be credited with the proceeds of the sale. Debtor agrees that in the event Debtor or any Obligor is entitled to receive any notice under the Code, as it exists in the state governing any such notice, of the sale or other disposition of any Collateral, reasonable notice shall be deemed given when such notice is deposited in a depository

receptacle under the care and custody of the United States Postal Service, postage prepaid, at such party’s address set forth on the first page hereof, ten (10) days prior to the date of any public sale, or after which a private sale, of any of such Collateral is to be held. Secured Party shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. Secured Party may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned.

(b) Application of Proceeds. If any Event of Default shall have occurred, Secured Party may at its discretion apply or use any cash held by Secured Party as Collateral, and any cash proceeds received by Secured Party in respect of any sale or other disposition of, collection from, or other realization upon, all or any part of the Collateral as follows in such order and manner as Secured Party may elect:

(c) Deficiency. In the event that the proceeds of any sale of, collection from, or other realization upon, all or any part of the Collateral by Secured Party are insufficient to pay all amounts to which Secured Party is legally entitled, Obligor and any party who guaranteed or is otherwise obligated to pay all or any portion of the Indebtedness shall be liable for the deficiency, together with interest thereon as provided in the Loan Documents, to the full extent permitted by the Code.

(d) Non-Judicial Remedies. In granting to Secured Party the power to enforce its rights hereunder without prior judicial process or judicial hearing, Debtor expressly waives, renounces and knowingly relinquishes any legal right which might otherwise require Secured Party to enforce its rights by judicial process. Debtor recognizes and concedes that non-judicial remedies are consistent with the usage of trade, are responsive to commercial necessity and are the result of a bargain at arm’s length. Nothing herein is intended to prevent Secured Party or Debtor from resorting to judicial process at either party’s option.

(e) Other Recourse. Debtor waives any right to require Secured Party to proceed against any third party, exhaust any Collateral or other security for the Indebtedness, or to have any third party joined with Debtor in any suit arising out of the Indebtedness or any of the Loan Documents, or pursue any other remedy available to Secured Party. Debtor further waives any and all notice of acceptance of this Agreement and of the creation, modification, rearrangement, renewal or extension of the Indebtedness. Debtor further waives any defense arising by reason of any disability or other defense of any third party or by reason of the cessation from any cause whatsoever of the liability of any third party. Until all of the Indebtedness shall have been paid in full, Debtor shall have no right of subrogation and Debtor waives the right to enforce any remedy which Secured Party has or may hereafter have against any third party, and waives any benefit of and any right to participate in any other security whatsoever now or hereafter held by Secured Party. Debtor authorizes Secured Party, and without notice or demand and without any reservation of rights against Debtor and without affecting Debtor’s liability hereunder or on the Indebtedness to (i) take or hold any other property of any type from any third party as security for the Indebtedness, and exchange, enforce, waive and release any or all of such other property, (ii) apply such other property and direct the order or manner of sale thereof as Secured Party may in its discretion determine, (iii) renew, extend, accelerate, modify, compromise, settle or release any of the Indebtedness or other security for the Indebtedness, (iv) waive, enforce or modify any of the provisions of any of the Loan Documents executed by any third party, and (v) release or substitute any third party.

9. Indemnity. As provided in the Code, Debtor hereby indemnifies and agrees to hold harmless Secured Party, and its officers, directors, employees, agents and representatives (each an “Indemnified Person”) from and against any and all liabilities, obligations, claims, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature (collectively, the “Claims”) which may be imposed on, incurred by, or asserted against, any Indemnified Person arising in connection with the Loan Documents, the Indebtedness or the Collateral (including without limitation, the enforcement of the Loan Documents and the defense of any Indemnified Person’s actions and/or inactions in connection with the Loan Documents), WHETHER OR NOT THE CLAIMS ARE IN ANY WAY OR TO ANY EXTENT CAUSED BY OR ARISE OUT OF SUCH INDEMNIFIED PARTY’S OWN NEGLIGENCE OR ANY CLAIM OR THEORY OF STRICT LIABILITY, except to the extent the Claims are proximately caused by such Indemnified Party’s

individual gross negligence or willful misconduct. The indemnification provided for in this Section shall survive the termination of this Agreement and shall extend and continue to benefit each individual or entity who is or has at any time been an Indemnified Person hereunder.

10. Miscellaneous.

(a) Entire Agreement. This Agreement contains the entire agreement of Secured Party and Debtor with respect to the Collateral. If the parties hereto are parties to any prior agreement, either written or oral, relating to the Collateral, the terms of this Agreement shall amend and supersede the terms of such prior agreements as to transactions on or after the effective date of this Agreement, but all security agreements, financing statements, guaranties, other contracts and notices for the benefit of Secured Party shall continue in full force and effect to secure the Indebtedness unless Secured Party specifically releases its rights thereunder by separate release.

(b) Amendment. No modification, consent or amendment of any provision of this Agreement or any of the other Loan Documents shall be valid or effective unless the same is authenticated by the party against whom it is sought to be enforced, except to the extent of amendments specifically permitted by the Code without authentication by the Debtor or Obligor.

(c) Actions by Secured Party. The lien, security interest and other security rights of Secured Party hereunder shall not be impaired by (i) any renewal, extension, increase or modification with respect to the Indebtedness, (ii) any surrender, compromise, release, renewal, extension, exchange or substitution which Secured Party may grant with respect to the Collateral, or (iii) any release or indulgence granted to any endorser, guarantor or surety of the Indebtedness. The taking of additional security by Secured Party shall not release or impair the lien, security interest or other security rights of Secured Party hereunder or affect the obligations of Debtor hereunder.

(d) Waiver by Secured Party. Secured Party may waive any Event of Default without waiving any other prior or subsequent Event of Default. Secured Party may remedy any default without waiving the Event of Default remedied.
