          (f) Whenever the Grantor, either by itself or through any agent, employee, licensee or designee, shall file an application for the registration of any Intellectual Property 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, the Grantor shall report such filing to the First Lien Agent within five Business Days after the last day of the fiscal quarter in which such filing occurs.

to the First Lien Agent for the benefit of the Secured Parties in such writing a security interest therein and in the proceeds thereof, all upon the terms of this Agreement, with such writing to be in form and substance reasonably satisfactory to the First Lien Agent.

SECTION 5. REMEDIAL PROVISIONS

          5.1 Certain Matters Relating to Receivables.

          (a) The First Lien Agent shall have the right, at any time after the occurrence and during the continuance of an Event of Default, to make test verifications of the Receivables in any manner and through any medium that it reasonably considers advisable, and the Grantor shall furnish all such assistance and information as the First Lien Agent may require in connection with such test verifications. At any time and from time to time after the occurrence and during the continuance of an Event of Default, upon the First Lien Agent’s request and at the expense of the Grantor, the Grantor shall cause independent public accountants or others satisfactory to the First Lien Agent to furnish to the First Lien Agent reports showing reconciliations, aging and test verifications of, and trial balances for, the Receivables.

          (b) Subject to Section 4.4, the First Lien Agent hereby authorizes the Grantor to collect the Grantor’s Receivables, subject to the First Lien Agent’s direction and control after the occurrence and during the continuance of an Event of Default, and the First Lien Agent may curtail or terminate said authority at any time after the occurrence and during the continuance of an Event of Default. If required by the First Lien Agent at any time after the occurrence and during the continuance of an Event of Default, any payments of Receivables, when collected by the Grantor, (i) shall be forthwith (and, in any event, within two Business Days) deposited by the Grantor in the exact form received, duly indorsed by the Grantor to the First Lien Agent if required, in a Collateral Account maintained under the sole dominion and control of the First Lien Agent, subject to withdrawal by the First Lien Agent for the account of the Secured Parties only as provided in Section 5.4, and (ii) until so turned over, shall be held by the Grantor in trust for the First Lien Agent and the Secured Parties, segregated from other funds of the Grantor. Each such deposit of Proceeds of Receivables shall be accompanied by a report identifying in reasonable detail the nature and source of the payments included in the deposit.

          (c) At the First Lien Agent’s request, the Grantor shall deliver to the First Lien Agent all original and other documents evidencing, and relating to, the agreements and transactions which gave rise to the Receivables, including, without limitation, all original orders, invoices and shipping receipts.

          5.2 Communications with Obligors: Grantors Remain Liable.

          (a) The First Lien Agent in its own name or in the name of others may at any time after the occurrence and during the continuance of an Event of Default communicate with obligors under the Receivables to verify with them to the First Lien Agent’s satisfaction the existence, amount and terms of any Receivables.

          (b) Upon the request of the First Lien Agent at any time after the occurrence and during the continuance of an Event of Default, the Grantor shall notify obligors on the Receivables that the Receivables have been assigned to the First Lien Agent for the ratable benefit of the Secured Parties and that payments in respect thereof shall be made directly to the First Lien Agent.

          (c) Anything herein to the contrary notwithstanding, the Grantor shall remain liable under each of the Receivables (or any agreement giving rise thereto) to observe and perform all the conditions and obligations to be observed and performed by it thereunder, all in accordance with the terms of any agreement giving rise thereto. Neither the First Lien Agent nor any Secured Party shall have any obligation or liability under any Receivable (or any agreement giving rise thereto) by reason of or arising out of this Agreement or the receipt by the First Lien Agent or any Secured Party of any payment relating thereto, nor shall the First Lien Agent or any Secured Party be obligated in any manner to perform any of the obligations of the Grantor under or pursuant to any Receivable (or any agreement giving rise thereto), to make any payment, to make any inquiry as to the nature or the sufficiency of any payment received by it or as to the sufficiency of any performance by any party thereunder, to present or file any claim, to take any action to enforce any performance or to collect the payment of any amounts that may have been assigned to it or to which it may be entitled at any time or times.

          5.3 Pledged Stock

          (a) Unless an Event of Default shall have occurred and be continuing and the First Lien Agent shall have given notice to the relevant Grantor of the First Lien Agent’s intent to exercise its corresponding rights pursuant to Section 5.3(b), the Grantor shall be permitted to receive all cash dividends paid in respect of the Pledged Stock and all payments made in respect of the Pledged Notes, in each case paid in the normal course of business of the relevant Issuer and consistent with past practice and to exercise all voting and corporate rights with respect to the Pledged Securities; provided, however, that no vote shall be cast or corporate right exercised or other action taken which, in the First Lien Agent’s reasonable judgment, would impair the Collateral or which would be inconsistent with or result in any violation of any provision of the Guaranty or this Agreement.

          (b) If an Event of Default shall occur and be continuing and the First Lien Agent shall give notice of its intent to exercise such rights to the Grantor (i) the First Lien Agent shall have the right to receive any and all cash dividends, payments or other Proceeds paid in respect of the Pledged Securities and make application thereof to the Grantor Obligations in the order set forth in Section 5.5, and (ii) any or all of the Pledged Securities shall be registered in the name of the First Lien Agent or its nominee, and the First Lien Agent or its nominee may thereafter exercise (x) all voting, corporate and other rights pertaining to such Pledged Securities at any meeting of shareholders of the relevant Issuer or Issuers or

otherwise and (y) any and all rights of conversion, exchange and subscription and any other rights, privileges or options pertaining to such Pledged Securities as if it were the absolute owner thereof (including, without limitation, the right to exchange at its discretion any and all of the Pledged Securities upon the merger, consolidation, reorganization, recapitalization or other fundamental change in the corporate structure of any Issuer, or upon the exercise by the Grantor or the First Lien Agent of any right, privilege or option pertaining to such Pledged Securities, and in connection therewith, the right to deposit and deliver any and all of the Pledged Securities with any committee, depositary, transfer agent, registrar or other designated agency upon such terms and conditions as the First Lien Agent may determine), all without liability except to account for property actually received by it, but the First Lien Agent shall have no duty to the Grantor to exercise any such right, privilege or option and shall not be responsible for any failure to do so or delay in so doing.

          (c) The Grantor hereby authorizes and instructs each Issuer of any Pledged Securities pledged by the Grantor hereunder to (i) comply with any instruction received by it from the First Lien Agent in writing that (x) states that an Event of Default has occurred and is continuing and (y) is otherwise in accordance with the terms of this Agreement, without any other or further instructions from the Grantor, and the Grantor agrees that each Issuer shall be fully protected in so complying, and (ii) unless otherwise expressly permitted hereby, pay any dividends or other payments with respect to the Pledged Securities directly to the First Lien Agent.

          5.4 Proceeds to be Turned Over to First Lien Agent. In addition to the rights of the First Lien Agent and the Secured Parties specified in Section 5.1 with respect to payments of Receivables, if an Event of Default shall occur and be continuing, all Proceeds received by the Grantor consisting of cash, checks and Instruments shall be held by the Grantor in trust for the First Lien Agent and the Secured Parties, segregated from other funds of the Grantor, and shall, forthwith upon receipt by the Grantor, be turned over to the First Lien Agent in the exact form received by the Grantor (duly indorsed by the Grantor to the First Lien Agent, if required). All Proceeds received by the First Lien Agent hereunder shall be held by the First Lien Agent in a Collateral Account maintained under its sole dominion and control. All Proceeds while held by the First Lien Agent in a Collateral Account (or by the Grantor in trust for the First Lien Agent and the Secured Parties) shall continue to be held as collateral security for all the Obligations and shall not constitute payment thereof until applied as provided in Section 5.5.

          5.5 Application of Proceeds. If an Event of Default shall have occurred and be continuing, at any time at the First Lien Agent’s election, the First Lien Agent may apply all or any part of Proceeds constituting Collateral, whether or not held in any Collateral Account, in payment of the Grantor Obligations as follows:

          First, pro rata based on the aggregate principal amount outstanding among the Guaranteed Obligations.

          Second, to the Grantor or to such other Person as a court of competent jurisdiction may direct.

          5.6 Code and Other Remedies. If an Event of Default shall occur and be continuing, the First Lien Agent, on behalf of the Secured Parties, may exercise, in addition to all other rights and remedies granted to them in this Agreement and in any other instrument or agreement securing, evidencing or relating to the Grantor Obligations, all rights and remedies of a secured party under the Maryland UCC or any other applicable law. Without limiting the generality of the foregoing, the First Lien Agent, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law referred to below) to or upon the Grantor or any other Person (all and each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any exchange, broker’s board or office of the First Lien Agent or any Secured Party or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. The First Lien Agent or any Secured Party shall have the right upon any such public sale or sales and, to the extent permitted by law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in the Grantor, which right or equity is hereby waived and released. The Grantor further agrees, at the First Lien Agent’s request, to assemble the Collateral and make it available to the First Lien Agent at places which the First Lien Agent shall reasonably select, whether at the Grantor’s premises or elsewhere. The First Lien Agent shall apply the net proceeds of any action taken by it pursuant to this Section 5.6 with respect to the Grantor’s Collateral, after deducting all reasonable costs and expenses of every kind incurred in connection therewith or incidental to the care or safekeeping of any of the Collateral of the Grantor or in any way relating to the Collateral of the Grantor or the rights of the First Lien Agent and the Secured Parties hereunder with respect thereto, including, without limitation, reasonable attorneys’ fees and disbursements, to the payment in whole or in part of the Obligations of the Grantor, in the order specified in Section 5.5, and only after such application and after the payment by the First Lien Agent of any other amount required by any provision of law, including, without limitation, Section 9-615(a)(3) of the Maryland UCC, need the First Lien Agent account for the surplus, if any, to the Grantor. To the extent permitted by applicable law, the Grantor waives all claims, damages and demands it may acquire against the First Lien Agent or any Secured Party arising out of the exercise by them of any rights hereunder. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least ten (10) days before such sale or other disposition.

          5.7 Registration Rights.

          (a) If the First Lien Agent shall determine to exercise its right to sell any or all of the Pledged Stock pursuant to Section 5.6, and if in the opinion of the First Lien Agent it is necessary or advisable to have the Pledged Stock, or that portion thereof to be sold, registered under the provisions of the Securities Act, the Grantor will cause the Issuer thereof to (i) execute and deliver, and cause the directors and officers of such Issuer to execute and deliver, all such instruments and documents, and do or cause to be done all such other acts as may be, in the opinion of the First Lien Agent, necessary or advisable to register the Pledged Stock, or that portion thereof to be sold, under the provisions of the Securities Act, (ii) use its best efforts

to cause the registration statement relating thereto to become effective and to remain effective for a period of one year from the date of the first public offering of the Pledged Stock, or that portion thereof to be sold, and (iii) make all amendments thereto and/or to the related prospectus which, in the opinion of the First Lien Agent, 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. The Grantor agrees to cause such Issuer to comply with the provisions of the securities or “Blue Sky” laws of any and all jurisdictions which the First Lien Agent shall designate and 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.

          (b) The Grantor recognizes that the First Lien Agent may be unable to effect a public sale of any or all the Pledged Stock, by reason of certain prohibitions contained in the Securities Act and applicable state securities laws or otherwise, and may be compelled to resort to one or more private sales thereof to a restricted group of purchasers that will be obliged to agree, among other things, to acquire such securities for their own account for investment and not with a view to the distribution or resale thereof. The Grantor acknowledges and agrees that any such private sale may result in prices and other terms less favorable than if such sale were a public sale and, notwithstanding such circumstances, agrees that any such private sale shall be deemed to have been made in a commercially reasonable manner. The First Lien Agent shall be under no obligation to delay a sale of any of the Pledged Stock for the period of time necessary to permit the Issuer thereof to register such securities for public sale under the Securities Act, or under applicable state securities laws, even if such Issuer would agree to do so.

          (c) The Grantor agrees to use its best efforts to do or cause to be done all such other acts as may be necessary to make such sale or sales of all or any portion of the Pledged Stock pursuant to this Section 5.7 valid and binding and in compliance with any and all other applicable Laws. The Grantor further agrees that a breach of any of the covenants contained in this Section 5.7 will cause irreparable injury to the First Lien Agent and the Secured Parties, that the First Lien Agent and the Secured Parties have no adequate remedy at law in respect of such breach and, as a consequence, that each and every covenant contained in this Section 5.7 shall be specifically enforceable against the Grantor, and the Grantor hereby waives and agrees not to assert any defenses against an action for specific performance of such covenants except for a defense that no Event of Default has occurred.

          5.8 Deficiency. The Grantor shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay the Grantor Obligations and the fees and disbursements of any attorneys employed by the First Lien Agent or any Secured Party to collect such deficiency.

SECTION 6. THE AGENT

          6.1 First Lien Agent’s Appointment as Attorney-in-Fact, etc.

          (a) The Grantor hereby irrevocably constitutes and appoints the First Lien Agent and any officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of the Grantor

and in the name of the Grantor or in its own name, for the purpose of carrying out the terms of this Agreement, to take any and all appropriate action and to execute any and all documents and instruments that may be necessary or desirable to accomplish the purposes of this Agreement and, without limiting the generality of the foregoing, the Grantor hereby gives the First Lien Agent the power and right, on behalf of the Grantor, without notice to or assent by the Grantor, to do any or all of the following:

                    (i) in the name of the Grantor or its own name, or otherwise, take possession of and indorse and collect any checks, drafts, notes, acceptances or other instruments for the payment of moneys due under any Receivable or with respect to any other Collateral and file any claim or take any other action or proceeding in any court of law or equity or otherwise deemed appropriate by the First Lien Agent for the purpose of collecting any and all such moneys due under any Receivable or with respect to any other Collateral whenever payable;

                    (ii) in the case of any Intellectual Property, execute and deliver, and have recorded, any and all agreements, instruments, documents and papers as the First Lien Agent may request to evidence the First Lien Agent’s and the Secured Parties’ security interest in such Intellectual Property and the goodwill and general intangibles of the Grantor relating thereto or represented thereby;

                    (iii) pay or discharge taxes and Liens levied or placed on or threatened against the Collateral, effect any repairs or any insurance called for by the terms of this Agreement and pay all or any part of the premiums therefor and the costs thereof;

                    (iv) execute, in connection with any sale provided for in Section 5.6 or 5.7, any indorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral;

                    (v) direct any party liable for any payment under any of the Collateral to make payment of any and all moneys due or to become due thereunder directly to the First Lien Agent or as the First Lien Agent shall direct;

                    (vi) ask or demand for, collect, and receive payment of and receipt for, any and all moneys, claims and other amounts due or to become due at any time in respect of or arising out of any Collateral;

                    (vii) sign and indorse any invoices, freight or express bills, bills of lading, storage or warehouse receipts, drafts against debtors, assignments, verifications, notices and other documents in connection with any of the Collateral;

                    (viii) commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the Collateral or any portion thereof and to enforce any other right in respect of any Collateral;

                    (ix) defend any suit, action or proceeding brought against the Grantor with respect to any Collateral;

                    (x) settle, compromise or adjust any such suit, action or proceeding and, in connection therewith, give such discharges or releases as the First Lien Agent may deem appropriate;

                    (xi) assign any Copyright, Patent or Trademark (along with the goodwill of the business to which any such Copyright, Patent or Trademark pertains), throughout the world for such term or terms, on such conditions, and in such manner, as the First Lien Agent shall in its sole discretion determine;

                    (xii) generally, sell, transfer, pledge and make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though the First Lien Agent were the absolute owner thereof for all purposes, and do, at the First Lien Agent’s option and the Grantor’s expense, at any time, or from time to time, all acts and things that the First Lien Agent deems necessary to protect, preserve or realize upon the Collateral and the First Lien Agent’s and the Secured Parties’ security interests therein and to effect the intent of this Agreement, all as fully and effectively as the Grantor might do; and

                    (xiii) license or sublicense whether on an exclusive or non-exclusive basis, any Intellectual Property for such term and on such conditions and in such manner as the First Lien Agent shall in its sole judgment determine and, in connection therewith, the Grantor hereby grants to the First Lien Agent for the benefit of the Secured Parties a royalty-free, world-wide irrevocable license of its Intellectual Property.

               Notwithstanding anything in this Section 6.1(a) to the contrary, the First Lien Agent agrees that it will not exercise any rights under the power of attorney provided for in this Section 6.1(a) unless an Event of Default shall have occurred and be continuing.

               (b) If the Grantor fails to perform or comply with any of its agreements contained herein, the First Lien Agent, at its option, but without any obligation so to do, may perform or comply, or otherwise cause performance or compliance, with such agreement.

               (c) The Grantor hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof. All powers, authorizations and agencies contained in this Agreement are coupled with an interest and are irrevocable until this Agreement is terminated and the Security Interest is released.

               (d) Notwithstanding anything to the contrary in this Section 6, the First Lien Agent agrees that it will not exercise any rights under the power of attorney provided for in this Section 6 unless it does so in accordance with, and to the extent consistent with, the terms of the Intercreditor Agreement.

          6.2 Duty of First Lien Agent. The First Lien Agent’s sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under Section 9-207 of the Maryland UCC or otherwise, shall be to deal with it in the same manner as the First Lien Agent deals with similar property for its own account. Neither the First Lien Agent, any Secured Party nor any of their respective officers, directors, employees or agents shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of

the Grantor or any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. The powers conferred on the First Lien Agent and the Secured Parties hereunder are solely to protect the First Lien Agent’s and the Secured Parties’ interests in the Collateral and shall not impose any duty upon the First Lien Agent or any Secured Party to exercise any such powers. The First Lien Agent and the Secured Parties shall be accountable only for amounts that they actually receive as a result of the exercise of such powers, and neither they nor any of their officers, directors, employees or agents shall be responsible to the Grantor for any act or failure to act hereunder, except for their own gross negligence or willful misconduct.

          6.3 Authorization of Financing Statements. Pursuant to any applicable law, the Grantor authorizes the First Lien Agent to file or record financing statements and other filing or recording documents or instruments with respect to the Collateral without the signature of the Grantor in such form and in such offices as the First Lien Agent determines appropriate to perfect the Security Interests. The Grantor authorizes the First Lien Agent to use the collateral description “all personal property,” other than the Excluded Assets, or “all assets,” other than the Excluded Assets, in any such financing statements. The Grantor hereby ratifies and authorizes the filing by the First Lien Agent of any financing statement with respect to the Collateral made prior to the date hereof.

          6.4 Authority of First Lien Agent. The Grantor acknowledges that the rights and responsibilities of the First Lien Agent under this Agreement with respect to any action taken by the First Lien Agent or the exercise or non-exercise by the First Lien Agent of any option, voting right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Agreement, as between the First Lien Agent and the Grantors, the First Lien Agent shall be conclusively presumed to be acting as agent for the Secured Parties with full and valid authority so to act or refrain from acting, and no Grantor shall be under any obligation, or entitlement, to make any inquiry respecting such authority.

SECTION 7. MISCELLANEOUS

          7.3 No Waiver by Course of Conduct; Cumulative Remedies. Neither the First Lien Agent nor any Secured Party shall by any act (except by a written instrument pursuant to Section 7.1), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Default or Event of Default. No failure to exercise, nor any delay in exercising, on the part of the First Lien Agent or any Secured Party, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the First Lien Agent or any Secured Party of any right or remedy hereunder on any one occasion shall not be construed as a bar to

any right or remedy which the First Lien Agent or such Secured Party would otherwise have on any future occasion. The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any other rights or remedies provided by law.

          7.4 Enforcement Expenses; Indemnification.

          (c) The Grantor agrees to pay, and to save the First Lien Agent and the Secured Parties harmless from, any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever with respect to the execution, delivery, enforcement, performance and administration of this Agreement.

          (d) The agreements in this Section shall survive repayment of the Guaranteed Obligations and all other amounts payable under the Guarantees.

The First Lien Agent and each Secured Party shall notify the Grantor promptly of any such set-off and the application made by the First Lien Agent or such Secured Party of the proceeds thereof, provided that the failure to give such notice shall

not affect the validity of such set-off and application. The rights of the First Lien Agent and each Secured Party under this Section are in addition to other rights and remedies (including, without limitation, other rights of set-off) which the First Lien Agent or such Secured Party may have.

          7.7 Counterparts. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts (including by telecopy), and all of said counterparts taken together shall be deemed to constitute one and the same instrument.

          7.8 Severability. Any provision of this Agreement 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, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.
