(a)           upon receipt of notice of the occurrence and continuance of an Event of Default from the Lender and without any request therefor by the Lender, so long as such Event of Default shall continue, to deliver (properly endorsed where required hereby or requested by the Lender) to the Lender all dividends and Distributions with respect to Investment Property, all interest, principal, other cash payments on Payment Intangibles, and all Proceeds of the Collateral, in each case thereafter received by such Grantor, all of which shall be held by the Lender as additional Collateral, except for payments made in accordance with Section 8.6 of the Credit Agreement; and

(b)           immediately upon the occurrence and during the continuance of an Event of Default and so long as the Lender has notified such Grantor of the Lender’s intention to exercise its voting power under this clause,

(i)            with respect to Collateral consisting of general partner interests or limited liability company interests, to promptly modify its Organic Documents to admit the Lender as a general partner or member, as applicable;

(ii)           that the Lender may exercise (to the exclusion of such Grantor) the voting power and all other incidental rights of ownership with respect to any Investment Property constituting Collateral and such Grantor hereby grants the Lender an irrevocable proxy, exercisable under such circumstances, to vote such Investment Property; and

(iii)          to promptly deliver to the Lender such additional proxies and other documents as may be necessary to allow the Lender to exercise such voting power.

All dividends, Distributions, interest, principal, cash payments, Payment Intangibles and Proceeds that may at any time and from time to time be held by such Grantor, but which such Grantor is then obligated to deliver to the Lender, shall, until delivery to the Lender, be held by such Grantor separate and apart from its other property in trust for the Lender. The Lender agrees that unless an Event of Default shall have occurred and be continuing and the Lender shall have given the notice referred to in clause (b), such Grantor will have the exclusive voting power with respect to any Investment Property constituting Collateral and the Lender will, upon the written request of such Grantor, promptly deliver such proxies and other documents, if any, as shall be reasonably requested by such Grantor which are necessary to allow such Grantor to exercise that voting power; provided that no vote shall be cast, or consent, waiver, or ratification given, or action taken by such Grantor that would impair any such Collateral or be inconsistent with or violate any provision of any Loan Document.

(a)                                 Each Grantor shall have the right to collect all Accounts so long as no Event of Default shall have occurred and be continuing.

(b)                                 Upon (i) the occurrence and continuance of an Event of Default and (ii) the delivery of notice by the Lender to each Grantor, all Proceeds of Collateral received by such Grantor shall be delivered in kind to the Lender for deposit in a Deposit Account of such Grantor maintained with the Lender (together with any other Deposit Accounts or Security Accounts pursuant to which any portion of the Collateral is deposited with the Lender, the “Collateral Accounts”), and such Grantor shall not commingle any such Proceeds, and shall hold separate and apart from all other property, all such Proceeds in express trust for the benefit of the Lender until delivery thereof is made to the Lender.

(c)                                  Following the delivery of notice pursuant to clause (b)(ii), and so long as an Event of Default shall continue, the Lender shall have the right to apply any amount in the Collateral Account to the payment of any Obligations which are then due and payable in accordance with Section 4.4(b) of the Credit Agreement.

(d)                                 With respect to each of the Collateral Accounts, it is hereby confirmed and agreed that (i) deposits in such Collateral Accounts are subject to a security interest as contemplated hereby, (ii) such Collateral Accounts shall be under the control of the Lender and (iii) the Lender shall have the sole right of withdrawal over such Collateral Account.

SECTION 4.4. As to Grantors Use of Collateral.

(a)                                 At any time following the occurrence and during the continuance of an Event of Default, whether before or after the maturity of any of the Obligations, the Lender may exercise any and all rights and remedies to which it is lawfully entitled with respect to the Collateral.

(b)                                 Upon the request of the Lender following the occurrence and during the continuance of an Event of Default, each Grantor will, at its own expense, notify any parties obligated on any of the Collateral to make payment to the Lender of any amounts due or to become due thereunder.

15

(a)                                 such Grantor will not (i) do or fail to perform any act whereby any of the Patent Collateral may lapse or become abandoned or dedicated to the public or unenforceable, (ii) permit any of its licensees to (A) fail to continue to use any of the Trademark Collateral in order to maintain all of the Trademark Collateral in full force free from any claim of abandonment for non-use, (B) fail to maintain the quality of products and services offered under all of the Trademark Collateral at a level substantially consistent with the quality of products and services offered under such Trademark as of the date hereof, (C) fail to employ all of the Trademark Collateral registered with any federal or state or foreign authority with an appropriate notice of such registration, (D) adopt or use any other Trademark which is confusingly similar or a colorable imitation of any of the Trademark Collateral, (E) use any of the Trademark Collateral registered with any federal, state or foreign authority except for the uses for which registration or application for registration of all of the Trademark Collateral has been made or (F) do or permit any act or knowingly omit to do any act whereby any of the Trademark Collateral may become invalid or unenforceable, or (iii) do or permit any act or knowingly omit to do any act whereby any of the Copyright Collateral or any of the Trade Secrets Collateral may lapse or become invalid or unenforceable or placed in the public domain except upon expiration of the end of an unrenewable term of a registration thereof, unless, in the case of any of the foregoing requirements in clauses (i), (ii) and (iii), such Grantor reasonably and in good faith determines that either (x) such Intellectual Property Collateral is of negligible economic value to such Grantor or (y) the loss of such Intellectual Property Collateral would not be material to such Grantor;

(b)                                 such Grantor shall promptly notify the Lender if it knows, or has reason to know, that any application or registration relating to any material item of the Intellectual Property Collateral may, in the Grantor’s reasonable commercial judgment, become abandoned or dedicated to the public or placed in the public domain or invalid or unenforceable, or of any adverse determination or development (including the institution of, or any such determination or development in, any proceeding in the United States Patent and Trademark Office, the United States Copyright Office or any foreign counterpart thereof or any court) regarding such Grantor’s ownership of any of the Intellectual Property Collateral, its right to register the same or to keep and maintain and enforce the same;

(c)                                  in no event will such Grantor or any of its agents, employees, designees or licensees file an application for the registration of any Intellectual Property Collateral with the United States Patent and Trademark Office, the United States Copyright Office or any similar office or agency in any other country or any political subdivision thereof, unless such Grantor promptly informs the Lender and, upon request of the Lender (subject to the terms of the Credit Agreement), executes and delivers all agreements, instruments and documents as the Lender may reasonably request to evidence the Lender’s security interest in such Intellectual Property Collateral; and

(d)                                 such Grantor will promptly (but no less than quarterly) execute and deliver to the Lender (as applicable) a Patent Security Agreement, Trademark Security Agreement and/or Copyright Security Agreement, as the case may be, in the forms of Exhibit A, Exhibit B and Exhibit C hereto following its obtaining an interest in any such

(b)                                 Upon the occurrence of an Event of Default, such Grantor will, promptly upon request by the Lender, (i) notify (and such Grantor hereby authorizes the Lender to notify) the issuer and each nominated person with respect to each of the Letters of Credit that the Proceeds thereof have been assigned to the Lender hereunder and any payments due or to become due in respect thereof are to be made directly to the Lender and (ii) arrange for the Lender to become the transferee beneficiary of such Letter of Credit.

SECTION 4.7. As to Commercial Tort Claims. Each Grantor covenants and agrees that, until the payment in full of the Obligations and termination of all Commitments, with respect to any Commercial Tort Claim hereafter arising, it shall deliver to the Lender a supplement in form and substance reasonably satisfactory to the Lender, together with all supplements to schedules thereto, identifying such new Commercial Tort Claim.

SECTION 4.8. Electronic Chattel Paper and Transferable Records. If any Grantor 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 U.S. Federal Electronic Signatures in Global and National Commerce Act, or in Section 16 of the U.S. Uniform Electronic Transactions Act as in effect in any relevant jurisdiction, with a value in excess of $100,000, such Grantor shall promptly notify the Lender thereof and, at the request of the Lender, shall take such action as the Lender may reasonably request to vest in the Lender control under Section 9-105 of the UCC 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. The Lender agrees with such Grantor that the Lender will arrange, pursuant to procedures satisfactory to the Lender and so long as such procedures will not result in the Lender’s loss of control, for the Grantor to make alterations to the electronic chattel paper or transferable record permitted under Section 9-105 of the UCC or, as the case may be, Section 201 of the U.S. Federal Electronic Signatures in Global and National Commerce Act or Section 16 of the U.S. Uniform Electronic Transactions Act for a party in control to allow without loss of control, unless an Event of Default has occurred and is continuing or would occur after taking into account any action by such Grantor with respect to such electronic chattel paper or transferable record.

SECTION 4.9. Further Assurances, etc. Each Grantor agrees that, from time to time at its own expense, it will, subject to the terms of this Agreement, promptly execute and deliver all further instruments and documents, and take all further action, that may be necessary or that the Lender may reasonably request, in order to perfect, preserve and protect any security interest

17

granted or purported to be granted hereby or to enable the Lender to exercise and enforce its rights and remedies hereunder with respect to any Collateral. Without limiting the generality of the foregoing, such Grantor will

(a)                                      from time to time upon the request of the Lender, promptly deliver to the Lender such stock powers, instruments and similar documents, reasonably satisfactory in form and substance to the Lender, with respect to such Collateral as the Lender may request and will, from time to time upon the request of the Lender, after the occurrence and during the continuance of any Event of Default, promptly transfer any securities constituting Collateral into the name of any nominee designated by the Lender; if any Collateral shall be evidenced by an Instrument, negotiable Document, Promissory Note or tangible Chattel Paper, deliver and pledge to the Lender hereunder such Instrument, negotiable Document, Promissory Note or tangible Chattel Paper (other than any Instrument, negotiable Document, Promissory Note or tangible Chattel Paper in principal amount less than $10,000) duly endorsed and accompanied by duly executed instruments of transfer or assignment, all in form and substance reasonably satisfactory to the Lender;

(b)                                      file (and hereby authorize the Lender to file) such Filing Statements or continuation statements, or amendments thereto, and such other instruments or notices (including any assignment of claim form under or pursuant to the federal assignment of claims statute, 31 U.S.C. § 3726, any successor or amended version thereof or any regulation promulgated under or pursuant to any version thereof), as may be necessary or that the Lender may reasonably request in order to perfect and preserve the security interests and other rights granted or purported to be granted to the Lender hereby;

(c)                                       at all times keep pledged to the Lender pursuant hereto, on a first-priority, perfected basis, at the request of the Lender, all Investment Property constituting Collateral, all dividends and Distributions with respect thereto, and all interest and principal with respect to Promissory Notes, and all Proceeds and rights from time to time received by or distributable to such Grantor in respect of any of the foregoing Collateral;

(d)                                      not create any tangible Chattel Paper without placing a legend on such tangible Chattel Paper reasonably acceptable to the Lender indicating that the Lender has a security interest in such Chattel Paper;

(e)                                       furnish to the Lender, from time to time at the Lender’s request, statements and schedules further identifying and describing the Collateral and such other reports in connection with the Collateral as the Lender may reasonably request, all in reasonable detail; and

(f)                                        do all things reasonably requested by the Lender in accordance with this Security Agreement in order to enable the Lender to have and maintain control over the Collateral consisting of Investment Property, Deposit Accounts, Letter-of-Credit-Rights and Electronic Chattel Paper.

Each Grantor agrees that a carbon, photographic or other reproduction of this Security Agreement or any UCC financing statement covering the Collateral or any part thereof shall be

18

sufficient as a UCC financing statement where permitted by law. Each Grantor hereby authorizes the Lender to file financing statements describing as the collateral covered thereby “all of the debtor’s personal property or assets” or words to that effect, notwithstanding that such wording may be broader in scope than the Collateral described in this Security Agreement.

ARTICLE V
THE LENDER

SECTION 5.1. Lender Appointed Attorney-in-Fact. Each Grantor hereby irrevocably appoints the Lender as its attorney-in-fact, with full authority in the place and stead of such Grantor and in the name of such Grantor or otherwise, from time to time in the Lender’s discretion, following the occurrence and during the continuance of an Event of Default, to take any action and to execute any instrument which the Lender may deem necessary or advisable to accomplish the purposes of this Security Agreement, including:

(a)                                 to ask, demand, collect, sue for, recover, compromise, receive and give acquittance and receipts for moneys due and to become due under or in respect of any of the Collateral;

(b)                                 to receive, endorse, and collect any drafts or other Instruments, Documents and Chattel Paper, in connection with clause (a) above;

(c)                                  to file any claims or take any action or institute any proceedings which the Lender may deem necessary or desirable for the collection of any of the Collateral or otherwise to enforce the rights of the Lender with respect to any of the Collateral; and

(d)                                 to perform the affirmative obligations of such Grantor hereunder.

Each Grantor hereby acknowledges, consents and agrees that the power of attorney granted pursuant to this Section is irrevocable and coupled with an interest.

SECTION 5.2. Lender May Perform. If any Grantor fails to perform any agreement contained herein, upon 5 days after the earlier to occur of (i) notice thereof given to any such Grantor by the Lender or (ii) the date on which such Grantor has knowledge of such failure, the Lender may itself perform, or cause performance of, such agreement, that the Lender deems necessary for the maintenance, preservation or protection of any of the Collateral or of its security interest therein to the extent provided for herein, and the expenses of the Lender incurred in connection therewith shall be payable by such Grantor pursuant to Section 10.3 of the Credit Agreement.

SECTION 5.3. Lender Has No Duty. The powers conferred on the Lender hereunder are solely to protect its interest in the Collateral and shall not impose any duty on it to exercise any such powers. Except for reasonable care of any Collateral in its possession and the accounting for moneys actually received by it hereunder, the Lender shall have no duty as to any Collateral or responsibility for

19

(a)                                      ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any Investment Property, whether or not the Lender has or is deemed to have knowledge of such matters, or

(b)                                      taking any necessary steps to preserve rights against prior parties or any other rights pertaining to any Collateral.

SECTION 5.4. Reasonable Care. The Lender is required to exercise reasonable care in the custody and preservation of any of the Collateral in its possession; provided that the Lender shall be deemed to have exercised reasonable care in the custody and preservation of any of the Collateral, if it takes such action for that purpose as each Grantor reasonably requests in writing at times other than upon the occurrence and during the continuance of any Event of Default, but failure of the Lender to comply with any such request at any time shall not in itself be deemed a failure to exercise reasonable care.

SECTION 5.5. Lender as Agent for Other Secured Parties. The Lender hereby agrees to act as agent of the other parties to which any Grantor may owe any Obligations for all purposes hereunder and under the other Loan Documents pursuant to which any Grantor grants a Lien or other right in any Collateral to secure the Obligations, for purposes of acquiring, holding and enforcing any and all Liens on any Collateral granted by any Grantor to secure any of the Obligations. The Lender may appoint any co-agents, sub-agents or attorneys-in-fact in connection with the foregoing.

ARTICLE VI
REMEDIES

SECTION 6.1. Certain Remedies. If any Event of Default shall have occurred and be continuing:

(a)                            The Lender may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of the Lender on default under the UCC (whether or not the UCC applies to the affected Collateral) and also may

(i)                                          take possession of any Collateral not already in its possession without demand and without legal process;

(ii)                                       require each Grantor to, and each Grantor hereby agrees that it will, at its expense and upon request of the Lender forthwith, assemble all or part of the Collateral as directed by the Lender and make it available to the Lender at a place to be designated by the Lender that is reasonably convenient to both parties,

(iii)                                    enter onto the property where any Collateral is located and take possession thereof without demand and without legal process; and

20

(iv)            without notice except as specified below, lease, license, sell or otherwise dispose of the Collateral or any part thereof in one or more parcels at any public or private sale, at any of the Lender’s offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as the Lender may deem commercially reasonable. Each Grantor agrees that, to the extent notice of sale shall be required by law, at least ten (10) days’ prior notice to such Grantor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. The Lender shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Lender 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)           All cash Proceeds received by the Lender in respect of any sale of, collection from, or other realization upon, all or any part of the Collateral shall be applied by the Lender against all or any part of the Obligations as set forth in Section 4.4(b) of the Credit Agreement.

(c)           The Lender may

(i)            transfer all or any part of the Collateral into the name of the Lender or its nominee, with or without disclosing that such Collateral is subject to the Lien hereunder,

(ii)           notify the parties obligated on any of the Collateral to make payment to the Lender of any amount due or to become due thereunder,

(iii)          withdraw, or cause or direct the withdrawal, of all funds with respect to the Collateral Account;

(iv)          enforce collection of any of the Collateral by suit or otherwise, and surrender, release or exchange all or any part thereof, or compromise or extend or renew for any period (whether or not longer than the original period) any obligations of any nature of any party with respect thereto,

(v)           endorse any checks, drafts, or other writings in any Grantor’s name to allow collection of the Collateral,

(vi)          take control of any Proceeds of the Collateral, and

(vii)         execute (in the name, place and stead of any Grantor) endorsements, assignments, stock powers and other instruments of conveyance or transfer with respect to all or any of the Collateral.

SECTION 6.2. Securities Laws. If the Lender shall determine to exercise its right to sell all or any of the Collateral that are Capital Securities pursuant to Section 6.1(a)(iv), each Grantor acknowledges that the Lender may be unable to effect a public sale or other disposition of the Capital Securities by reason of certain prohibitions contained in the Securities Act of 1933, as

21

from time to time amended (the “Securities Act”), federal banking laws, and other applicable laws, but may be compelled to resort to one or more private sales thereof to a restricted group of purchasers. Each Grantor agrees that any such private sale may be at prices and other terms less favorable to the seller than if sold at public sales and that such private sales shall not solely by reason thereof be deemed not to have been made in a commercially reasonable manner. The Lender shall be under no obligation to delay a sale of any of the Capital Securities for the period of time necessary to permit the issuer of such securities to register such securities for public sale under the Securities Act, or such other federal banking or other applicable laws, even if the issuer would agree to do so. Subject to the foregoing, the Lender agrees that any sale of the Capital Securities shall be made in a commercially reasonable manner, and each Grantor agrees to use its reasonable best efforts to cause the issuer or issuers of the Capital Securities contemplated to be sold, to execute and deliver, all at the Grantors’ expense, all such instruments and documents, and to do or cause to be done all such other acts and things as may be necessary or, in the reasonable opinion of the Lender, advisable to exempt such Capital Securities from registration under the provisions of the Securities Act, and to make all amendments to such instruments and documents which, in the opinion of the Lender, are necessary or advisable, all in conformity with the requirements of the Securities Act and the rules and regulations of the Securities and Exchange Commission applicable thereto. Each Grantor further agrees to use its reasonable best efforts (a) to cause such issuer or issuers to exempt or comply with the provisions of the securities or “Blue Sky” laws of any jurisdiction which the Lender designates and obtain all necessary governmental approvals for the sale of the Capital Securities, as requested by the Lender; (b) if required, to cause such issuer or issuers to make available to its security holders, as soon as practicable, an earnings statement (which need not be audited) which will satisfy the provisions of Section 11(a) of the Securities Act; and (c) to do or cause to be done all such other acts and things as may be necessary to make such sale of the Collateral or any part thereof valid and binding and in compliance with applicable law.

SECTION 6.3. Compliance with Restrictions. Each Grantor agrees that in any sale of any of the Collateral whenever an Event of Default shall have occurred and be continuing, the Lender is hereby authorized to comply with any limitation or restriction in connection with such sale as it may be advised by counsel is necessary in order to avoid any violation of applicable law (including compliance with such procedures as may restrict the number of prospective bidders and purchasers, require that such prospective bidders and purchasers have certain qualifications, and restrict such prospective bidders and purchasers to Persons who will represent and agree that they are purchasing for their own account for investment and not with a view to the distribution or resale of such Collateral), or in order to obtain any required approval of the sale or of the purchaser by any Governmental Authority or official, and such Grantor further agrees that such compliance shall not result in such sale being considered or deemed not to have been made in a commercially reasonable manner, nor shall the Lender be liable nor accountable to such Grantor for any discount allowed by the reason of the fact that such Collateral is sold in compliance with any such limitation or restriction.

SECTION 6.4. Protection of Collateral. The Lender may from time to time, at its option, perform any act which any Grantor fails to perform after being requested in writing so to perform (it being understood that no such request need be given after the occurrence and during the continuance of an Event of Default) and the Lender may from time to time take any other action

22

which the Lender deems necessary for the maintenance, preservation or protection of any of the Collateral or of its security interest therein.
