lien or security interest in any collateral which secures the obligations of Borrower, any Grantor, or any other guarantor, or (ii) protect the property covered by such lien or security interest.

(b)agrees to make no claim on such indebtedness until after the Termination Date.

(c)further agrees not to assign all or any part of such indebtedness without the prior written consent of Administrative Agent, which consent may be granted or withheld by Administrative Agent in its sole and absolute discretion.

at any time after the occurrence and during the continuation of an Event of Default, Grantor shall deposit, or cause to be deposited, all checks, drafts, cash and other remittances in payment of, or on account of payment of, any and all Accounts and Chattel Paper (all of the foregoing herein collectively referred to as “Items of Payment”) to an account (the “Collateral Account”) designated by Administrative Agent at a bank or other financial institution designated by Administrative Agent. Administrative Agent shall not be responsible for the solvency of any such bank or other financial institution, or the management and administration of the Collateral Account. Administrative Agent alone shall have the power to access and make withdrawals from the Collateral Account. Grantor shall deposit such Items of Payment for credit to the Collateral Account within two (2) Business Days of the receipt thereof and in precisely the form received, except for the endorsement of Grantor where necessary to permit the collection of such Items of Payment, which endorsement Grantor hereby agrees to make. Pending such deposit, Grantor will not commingle any such Items of Payment with any of its other funds or property, but will hold them separate and apart. Administrative Agent shall be entitled, from time to time in Administrative Agent’s discretion, to apply the funds in the Collateral Account against any of the Obligations. Once no Event of Default is outstanding, Administrative Agent shall return all Items of Payment maintained in the Collateral Account to Borrower.

5.16Additional Covenants Relating to Intellectual Property.

(a)Except in the Ordinary Course of Business or as otherwise permitted under the Credit Agreement, Grantor will not transfer or grant an exclusive or non-exclusive license relating to, or otherwise dispose of any material intellectual property without the prior written consent of Administrative Agent, (not to be unreasonably withheld or delayed).

(b)Grantor shall not file any application for the issuance of a patent or trademark with the United States Patent and Trademark Office or any similar office or agency in the United States or any other country, unless Grantor has notified Administrative Agent in writing of such action within 30 days thereafter and, upon the reasonable request of Administrative Agent, Grantor shall execute and deliver to Administrative Agent any and all assignments, agreements, instruments, documents and such other papers as may be reasonably requested by Administrative Agent to effect an assignment of such application to Administrative Agent.

(c)Grantor will not do any act, nor omit to do any act, whereby any such patents or trademarks, once granted and which remain useful, in any material respect, to Grantor’s business, may become abandoned or unenforceable, and Grantor shall notify Administrative Agent promptly if it knows or has reason to know of any reason why any application, material to the business, may become abandoned, invalidated or the subject of any suit.

(d)Grantor will render any assistance reasonably necessary to Administrative Agent without cost in any proceeding before the United States Patent and Trademark Office or any similar office or agency in the United States or any other country to maintain each application, material to the business, for any patents, copyrights, trademarks or other Intellectual Property, including, without limitation, the filing of all renewals and the payment of all annuities.

5.17Notice to the Secured Party; Joinder by Grantor. Grantor will notify Administrative Agent within ten (10) Business Days if Grantor should learn of any unauthorized use or infringement of a material nature by any Person with respect to any of the material Collateral. Following any such notice, if reasonably requested by Administrative Agent, Grantor, at Grantor’s expense, shall join with Administrative Agent in such action as Administrative Agent, in its discretion, may deem advisable for the protection of the valid and enforceable (subject to Permitted Liens) first priority Lien of Administrative Agent.

article 7

DEFAULT AND REMEDIES

Upon the occurrence and during the continuation of an Event of Default (including, without limitation, any Grantor’s breach of any representation or warranty under this Agreement or violation or failure to perform under any of the covenants contained in this Agreement, but subject to the terms of the Credit Agreement), Administrative Agent shall immediately be entitled to exercise, in addition to those available at law or in equity, all of the following rights and remedies:

7.1Collection. Administrative Agent may proceed directly and at once without notice against any Grantor to collect and recover the full amount of the liability hereunder, or any portion thereof, without proceeding against any Loan Party or any other Person, or endorser, surety or guarantor, or foreclosing upon, selling, or otherwise disposing of, or enforcing, or collecting or applying any Collateral, Administrative Agent may then have as security for the Obligations, and without enforcing or proceeding under any other guaranty.

7.2Assemble Collateral. Administrative Agent may require any Grantor (at such Grantor’s sole expense) to assemble and to forward promptly any or all of the Goods, Equipment, Chattel Paper, and Inventory to Administrative Agent at such location(s) as shall be reasonably required by Administrative Agent.

7.3Take Possession. Without breaching the peace, Administrative Agent may enter upon the premises where any Goods, Equipment, Chattel Paper, monies, deposit accounts or rights to money are located and take immediate possession thereof, by summary proceedings or otherwise, and Administrative Agent may remove any of such items, all without liability of Administrative Agent to any Grantor for or by reason of such entry, taking of possession or removal in the absence of gross negligence thereof.

16

82956925

7.4Appointment of Receiver. Administrative Agent shall be entitled to appointment of a receiver to take possession of and to manage all or any portion of the Collateral. Administrative Agent may obtain such appointment without notice to, or demand of any Grantor, on an ex parte basis before any court of competent jurisdiction, and without regard to the adequacy of the Collateral as security for the Obligations.

7.5Sale of Collateral. Administrative Agent may sell, assign, and deliver or otherwise dispose of or cause to be sold or otherwise disposed of, the whole or any part of the Collateral, at one or more commercially reasonable public or private sales, without demand or advertisement of the time or place of sale or of any adjournment thereof, each of which is hereby expressly waived. The sale or other disposition may be made for such price and upon such terms and conditions as Administrative Agent may deem best in its exercise of its commercially reasonable discretion. Administrative Agent shall apply the proceeds from such sale or sales or such other disposition or dispositions: first, to the settlement of all liens or claims on the Collateral with a lien priority greater than that of Administrative Agent; second, to the payment of all reasonable expenses connected with the assembly, preservation, preparation, and sale or other disposition of the Collateral, including any trustees’ or auctioneers’ fees, commissions or other expenses; third, to the payment of all amounts due under the Loans and all other monetary Obligations; and fourth, returning the excess, if any, to the Borrower. Each Grantor hereby expressly waives all rights of appraisal, whether before or after the sale or other disposition, and any right of redemption after the sale or other disposition. Each Grantor shall have the right to redeem any of the Collateral up to the time of the sale or other disposition by paying to Administrative Agent, the aggregate amount of the Obligations, together with all costs incurred by Administrative Agent in collecting such amounts or in enforcing its rights and remedies hereunder, and any other monetary Obligations then due and owing.

7.6Attorney-in-Fact. Each Grantor hereby irrevocably appoints Administrative Agent as such Grantor’s attorney-in-fact, with power of substitution, to do each of the following in the name of such Grantor and on its own behalf or in the name of Administrative Agent or otherwise, for the use and benefit of Administrative Agent, but at the cost and expense of such Grantor, and without notice to such Grantor:

(f)following the occurrence of an Event of Default, repair, alter or supply goods, if any, necessary to fulfill in whole or in part the purchase order of any Account Debtor;

(j)following the occurrence of an Event of Default, endorse the name of Grantor upon any items of payment relating to the Collateral or upon any proof of claim in bankruptcy against an Account Debtor;

(k)following the occurrence of an Event of Default, institute and prosecute legal and equitable proceedings to reclaim any of the goods sold to any debtor obligated on an Account, Chattel Paper, or General Intangible at a time when such debtor was insolvent;

(l)following the occurrence of an Event of Default, receive and open all mail addressed to Grantor and notify the postal authorities to change the addresses for the delivery of mail to Grantor to such addresses as Administrative Agent may designate; and

(m)following the occurrence of an Event of Default, execute and deliver on behalf of Grantor one or more instruments of assignment of the Intellectual Property (or application, letters patent or recording relating thereto), in form suitable for filing, recording or registration.

The foregoing powers are coupled with an interest and are irrevocable so long as any monetary Obligations remain outstanding. This appointment may be discharged by any officer or attorney of such attorney-in-fact.

7.7Right to Make Payments or Otherwise Cure. Administrative Agent may take any actions, make any payments, or incur any reasonable expenses (including, without limitation, the payment of filing fees, court costs, travel expenses and reasonable attorneys’ fees) as may be necessary or appropriate to preserve, defend, protect, maintain, record or enforce the Obligations, the Collateral, or the assignment granted hereunder.

7.8Intellectual Property Remedies. In addition to all other rights and remedies, Administrative Agent, following the occurrence and during the continuation of an Event of Default, shall have the following rights and remedies with respect to intellectual property, each of which

18

82956925

may be exercised without notice to, or consent by, any Grantor except as expressly provided for herein:

(a)Administrative Agent may require that Grantor immediately discontinue any existing use of intellectual property and that Grantor not make further use of intellectual property for any purpose whatsoever;

(b)Upon ten (10) calendar days’ prior notice to Grantor, Administrative Agent may grant one or more exclusive or non-exclusive license or licenses relating to any of intellectual property for such term or terms, on such conditions, and in such manner, as Administrative Agent shall in its sole discretion deem appropriate. Such license or licenses may be general, special or otherwise, and may be granted on an exclusive or non-exclusive basis throughout the United States of America, its territories and possessions, and throughout all foreign countries;

(c)Upon ten (10) calendar days’ prior notice to any Grantor, Administrative Agent may assign, sell or otherwise dispose of intellectual property Property or any part thereof, either with or without special conditions or stipulations.

(d)Administrative Agent may first apply the proceeds actually received from any such license, assignment, sale or other disposition of intellectual property to the reasonable costs and expenses thereof, including, without limitation, reasonable attorneys’ fees and all legal, travel and other expenses which may be incurred by Administrative Agent. Thereafter, Administrative Agent may apply any remaining proceeds to such of the Obligations as Administrative Agent may in its sole discretion determine. Each Grantor shall remain liable to Administrative Agent for any expenses or the Obligations remaining unpaid after the application of such proceeds, and Grantors will pay Administrative Agent on demand any such unpaid amount; and

(e)If any such license, assignment, sale or other disposition of intellectual property (or any part thereof) is made after the occurrence of an Event of Default under any of the Loan Documents, each Grantor shall supply to Administrative Agent or Administrative Agent’s designee, such Grantor’s knowledge and expertise relating to the manufacture and sale of the products according to the patented inventions, such Grantor’s customer lists, and other records relating to the distribution of any products related thereto.

article 8ADDITIONAL PROVISIONS

8.1Independent and Separate Obligations. The obligations of each Grantor hereunder shall be absolute and unconditional and are independent of the obligations of such Grantor or of any other person, endorser, surety or guarantor; and, in the event of any Default hereunder, a separate action or actions may be brought and prosecuted against any Grantor whether or not such Grantor

19

82956925

is the alter ego of any Loan Party and whether or not such Grantor is joined therein or a separate action or actions are brought against Borrower. Administrative Agent’s rights hereunder shall not be exhausted until all of the Obligations have been indefeasibly paid in full and performed (other than Contingent Obligations not then due).

8.2Deficiency. EachGrantor shall be and remain liable for all of the Obligations remaining after crediting to such Grantor any net proceeds received by Administrative Agent following exercise of any of its rights and remedies hereunder.

8.3Secured Cash Management Agreements and Secured Hedge Agreements. No Secured Party that obtains the benefit of this Agreement shall have any right to notice of any action or to consent to, direct or object to, any action hereunder or otherwise in respect of the Collateral (including, without limitation, the release or impairment of any Collateral) other than in its capacity as a Lender, the LC Issuing Lenderor the Administrative Agent, as applicable, and, in any such case, only to the extent expressly provided in the Loan Documents. Notwithstanding any other provision of this Agreement to the contrary, the Administrative Agent shall only be required to verify the payment of, or that other satisfactory arrangements have been made with respect to, the Obligations arising under any Secured Cash Management Agreement and any Secured Hedge Agreement to the extent the Administrative Agent has received written notice of such Obligations, together with such supporting documentation as it may request, from the applicable Lender or Affiliate of a Lender, as the case may be. Each Secured Party not a party to the Credit Agreement that obtains the benefit of this Agreement shall be deemed to have acknowledged and accepted the appointment of the Administrative Agent pursuant to the terms of the Credit Agreement, and that with respect to the actions and omissions of the Administrative Agent hereunder or otherwise relating hereto that do or may affect such Secured Party, the Administrative Agent and each of its Related Parties shall be entitled to all the rights, benefits and immunities conferred under Section 9 of the Credit Agreement.

8.4No Duty to Act. Nothing contained in this Agreement or any of the other Loan Documents shall be construed as requiring Administrative Agent to take any particular enforcement or remedial action or combination of enforcement or remedial actions at any time.

8.5Bankruptcy.

(a)All of the Obligations shall, at the option of Administrative Agent, forthwith become due and payable if there shall be filed against Borrower a petition in bankruptcy or for insolvency proceedings or for reorganization, dissolution or liquidation, or for appointment of a receiver or trustee, or if Borrower or any Grantor makes an assignment for the benefit of creditors. This Agreement shall remain in full force and effect, without abatement, until the Obligations have been paid or performed in full and all other obligations guaranteed hereunder have been performed (other than Contingent Obligations not then due) to the satisfaction of Administrative Agent, it being expressly understood and agreed to by each Grantor that this Agreement shall continue to be effective or shall be reinstated, as the case may be, if at any time payment, in whole or in part, of any of the Obligations is rescinded, invalidated, declared to be fraudulent or preferential, set aside or must otherwise be restored or returned by Administrative Agent upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of any Grantor all as though such payment had not been

20

82956925

made, to Grantor or a trustee, receiver or any other party. Each Grantor understands and agrees that in the event Administrative Agent is required to so return all or any portion of a payment received from Borrower, such Grantor shall be required to pay Administrative Agent for such amount.

(b)So long as any of the obligations guaranteed hereunder shall be owing to Administrative Agent, no Grantor shall, without the prior written consent of Administrative Agent, commence or join with any other party in commencing any bankruptcy, reorganization or insolvency proceedings of or against any Grantor. Each Grantor understands and acknowledges that by virtue of this Agreement, it has specifically assumed any and all risks of a bankruptcy or reorganization case or proceeding with respect to such Grantor. As an example and not in any way of limitation, a subsequent modification of the Obligations in any reorganization case concerning any Grantor shall not affect the obligation of such Grantor to pay and perform the Obligations in accordance with its original terms. In any bankruptcy or other proceeding in which the filing of claims is required by Law, each Grantor shall file all claims which such Grantor may have against such Grantor or relating to any indebtedness of Borrower to such Grantor and shall assign to Administrative Agent all rights of such Grantor thereunder. If Grantor does not file any such claim, Administrative Agent, as attorney in fact for each Grantor, is hereby authorized to do so in the name of such Grantor or, in Administrative Agent’s discretion, to assign the claim to a nominee and to cause proof of claim to be filed in the name of Administrative Agent’s nominee. The foregoing power of attorney is coupled with an interest and cannot be revoked. Administrative Agent or its nominee shall have the right, in its reasonable discretion, to accept or reject any plan proposed in such proceeding and to take any other action which a party filing a claim is entitled to do. In all such cases, whether in administration, bankruptcy or otherwise, the person or persons authorized to pay such claim shall pay to Administrative Agent the amount payable on such claim and, to the full extent necessary for that purpose, each Grantor hereby assigns to Administrative Agent all of such Grantor’s rights to any such payments or distributions; provided, however, such Grantor’s obligations hereunder shall not be satisfied except to the extent that Administrative Agent receives cash by reason of any such payment or distribution. If Administrative Agent receives anything hereunder other than cash, the same shall be held as collateral for amounts due under this Agreement. Notwithstanding anything to the contrary herein, the liability of each Grantor hereunder shall be reinstated and revised, and the rights of Administrative Agent shall continue, with respect to any amount at any time paid by or on behalf of such Grantor on account of the Loan Documents which Administrative Agent shall restore or return by reason of the bankruptcy, insolvency or reorganization of such Grantor or for any other reasons, all as though such amount had not been paid.

8.6Remedies Not Limited; Partial Exercise. All of Administrative Agent’s rights and remedies, whether provided under this Agreement, the other Loan Documents, at law, in equity, or otherwise shall be cumulative and none is exclusive. Such rights and remedies may be enforced alternatively, successively or concurrently, and each Grantor hereby agrees that Administrative Agent may enforce its rights separately hereunder with respect to individual items or classes of Collateral without waiving or prejudicing in any respect Administrative Agent’s rights hereunder with respect to any other items or classes of Collateral. Administrative Agent may exercise any other right or remedy which may be available to it under this Agreement, the Credit Agreement or applicable Law, including, without limitation, the remedies set forth in Article 8 of the Credit

21

82956925

Agreement, or may proceed by appropriate court action to enforce the terms hereof, to recover damages for the breach hereof, or to rescind this Agreement in whole or in part.

8.7Costs of Enforcement. Subject to Section 10.4 of the Credit Agreement, eachGrantor shall be liable for all costs reasonably incurred by Administrative Agent or any Lender in collecting any sums owed to Administrative Agent under the Loan Documents or in otherwise enforcing any of the Obligations (whether or not suit is brought), including, without limitation, all reasonable attorneys’ fees and expenses, court costs, and reasonable costs of consultants, appraisers and other advisors retained by Administrative Agent. In the event of any Default, Administrative Agent may, in its own discretion, cure such Default and, if it does so, any expenditures made for such purpose shall be added to the principal of the Obligations.

8.8Mitigation of Damages. To the extent permitted by Law, each Grantor hereby waives any notice or other mandatory requirements of Law, now or hereafter in effect, which might require Administrative Agent to sell, lease or otherwise use any of the Collateral in mitigation of Administrative Agent’s damages; provided, however, that such Grantor does not waive any legal requirement that Administrative Agent act in a commercially reasonable manner.

8.9No Waivers by Administrative Agent or Lender. No failure of Administrative Agent or any Lender to exercise, or delay by Administrative Agent or any Lender in the exercise of, any of its rights and remedies granted herein following the occurrence of a Default or an Event of Default shall constitute a waiver of any of Administrative Agent’s or any Lender’s rights with respect to such Default or Event of Default or any subsequent Default or Event of Default (whether or not similar). Any failure or delay by Administrative Agent or any Lender to require strict performance by any Grantor of any of the provisions, warranties, terms and conditions contained herein or in any other agreement, document or instrument, shall not affect Administrative Agent’s or any Lender’s right to demand strict compliance and performance therewith.

8.10Waiver of Notice and Hearing Regarding Probable Cause by Grantor. Each Grantor acknowledges being advised of a constitutional right, as to pre-judgment relief as may be sought by Administrative Agent through the process of a court, to notice and a court hearing to determine whether, upon default, there is probable cause to sustain the validity of Administrative Agent’s claim and whether Administrative Agent is entitled to possession of the Collateral. Being so advised, each Grantor, in regard to such relief and to the fullest extent permitted by Law, hereby voluntarily gives up, waives and surrenders any right to a notice and hearing to determine whether there is probable cause to sustain the validity of Administrative Agent’s claim. Any notices required pursuant to any state or local law shall be deemed reasonable if mailed by Administrative Agent to the persons entitled thereto at their last known addresses at least ten (10) calendar days prior to disposition of the Collateral, and in reference to a private sale, need state only that Administrative Agent intends to negotiate such a sale.

8.11Administrative Agent’s Actions. Administrative Agent may take or release the Collateral or other security, may release any party primarily or secondarily liable for any Indebtedness to Administrative Agent, may grant extensions, renewals or indulgences with respect to such Indebtedness, and may apply any other security therefor held by it to the satisfaction of such

22

82956925

Indebtedness, all without prejudice to any of its rights or any Grantor’s obligations hereunder or under any of the other Loan Documents.

8.12Taxes. Subject to Section 3.1 of the Credit Agreement, all payments hereunder shall be made without any counterclaim of setoff, free and clear of, and without reduction by reason of, any taxes, levies, imposts, charges and withholdings, restrictions or conditions of any nature (other than on the income of Administrative Agent) (“Taxes”), which are now or may hereafter be imposed, levied or assessed by any country, political subdivision or taxing authority, all of which will be for the account of and paid by any Grantor hereunder. If for any reason, any such reduction is made or any Taxes are paid by Administrative Agent, subject to Section 3.1 of the Credit Agreement, Grantor will pay to Administrative Agent the additional amounts as may be necessary to ensure that it receives the same net amount that it would have received had no reduction been made of Taxes paid.

8.13Liability for Loss. Administrative Agent shall not be liable for any loss to the Collateral in its possession, nor shall such loss diminish the debt due, except for loss caused by Administrative Agent’s willful misconduct or gross negligence.

8.14Amendments and Waivers. No amendment or waiver of any provision of this Agreement nor consent to any departure by any Grantor therefrom shall be effective unless the same shall be in writing and signed by Administrative Agent and each Grantor. No failure on the part of Administrative Agent to exercise, and no delay in exercising, any right or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any right hereunder preclude any other or further exercise of any other right.

8.15Notices. All notices hereunder shall be given in accordance with the notice provisions in the Credit Agreement. Each Grantor agrees that ten (10) Business Days’ prior notice of the time and place of any public sale of all or any portion of the Collateral, or of the time after which a private sale of all or any portion of the Collateral will be made, is commercially reasonable notice.

8.16Joint and Several Obligations. Each Grantor’s obligations hereunder are joint and several obligation of all such Persons (including, without limitation, all makers, endorsers, guarantors and sureties, if any) and shall be binding on all such Persons and their respective heirs, executors, administrators, legal representatives, successors and assigns.

8.17Amendments and Modifications.The provisions of this Agreement shall extend and be applicable to all renewals, amendments, extensions and modifications of the Obligations and the documents, agreements and other instruments evidencing, securing or otherwise executed in connection with the Obligations, and all references to the Obligations and such documents, agreements or instruments shall be deemed to include any renewal, extension, amendment or modification thereof.

8.18Further Assurances. EachGrantor will promptly and duly execute and deliver to Administrative Agent such further documents and assurances and take such further actions as Administrative Agent may from time to time reasonably request in order to carry out the intent and

23

82956925

8.19Successors and Assigns. This Agreement shall be binding upon, and shall inure to the benefit of, each Grantor, Administrative Agent, and their respective successors and assigns.

8.20Assignment. EachGrantor acknowledges that it may not assign any of its rights or delegate any of its duties under this Agreement.

Upon the Termination Date, this Agreement shall terminate without further action by Administrative Agent; provided, however, that this Agreement shall remain in full force and effect and continue to be effective should any petition be filed by or against any Grantor for liquidation or reorganization, should any Grantor become insolvent or make an assignment for the benefit of any creditor or creditors or should a receiver or trustee be appointed for all or any significant part of any Grantor’s assets, and shall continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Obligations, or any part thereof, is, pursuant to Law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee of the Obligations, whether as a “voidable preference,” “fraudulent conveyance,” or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Obligations shall be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned. Upon termination of this Agreement, Administrative Agent will execute and deliver to each Grantor, at its expense, any releases, termination statements or similar instruments of reconveyance as such Grantor may reasonably request. Upon the Disposition of any Collateral (to the extent permitted under the Credit Agreement) or of any Subsidiary (to the extent permitted under the Credit Agreement), Administrative Agent will execute and deliver to each Grantor, at its expense, any releases, termination statements or similar instruments of reconveyance as such Grantor may reasonably request with respect to such Collateral or such Subsidiary.

8.24Severability. Any provision of this Agreement or of any related instrument or document executed pursuant hereto which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof or thereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. To the extent permitted by Law, each Grantor hereby waives any provision of law which renders any provision hereof or thereof prohibited or unenforceable in any respect.

8.25Headings. The section headings in this Agreement are included herein for convenience of reference only and shall not constitute a part of this Agreement for any other purpose. The exhibits attached hereto, are hereby incorporated by reference as a part of the Agreement with the same force and effect as if set forth in the body hereof.

8.26Counterparts. This Agreement may be executed in any number of counterparts, each of which when so executed and delivered shall be an original, but all of which shall together constitute one and the same instrument. Delivery of an executed counterpart of a signature page to this Agreement by facsimile, portable document format (“PDF”) or other electronic means shall be as effective as delivery of a manually executed counterpart of this Agreement. The effectiveness of any such documents and signatures shall, subject to applicable Law, have the same force and effect as manually signed originals and shall be binding on each Grantor and Administrative Agent. Administrative Agent may also require that any such documents and signatures be confirmed by a manually signed original thereof; provided, however, that the failure to request or deliver the same shall not limit the effectiveness of any facsimile document or signature. No party may raise the use of a facsimile, PDF or other electronic means, or the fact that any signature was transmitted through the use of a facsimile, PDF or other electronic means, as a defense to the enforcement of this Agreement.

8.27Credit Agreement. Nothing contained herein is intended to, nor shall, amend, modify or supplement the terms and conditions of the Credit Agreement or any other Loan Documents, nor restrict in any way, any rights or remedies Administrative Agent may have under the Credit Agreement or any of the other Loan Documents.
