                           partnership interests or limited liability company
                           interests to be treated as securities for purposes of
                           the UCC; unless such Debtor shall take all steps
                           necessary to establish Secured Party's "control"
                           thereof;

                  (ii)     in the event it acquires rights in any Investment
                           Property after the date hereof, it shall deliver to
                           Secured Party a completed Pledge Supplement,
                           substantially in the form of Exhibit A attached
                           hereto, together with a Supplement to Schedule 4.4,
                           reflecting such new Investment Property.
                           Notwithstanding the foregoing, it is understood and
                           agreed that the security interest of Secured Party
                           shall attach to all Investment Property immediately
                           upon any Debtor's acquisition of rights therein and
                           shall not be affected by the failure of any Debtor to
                           deliver a supplement to Schedule 4.4 as required
                           hereby;

                  (iii)    except as provided in the next sentence, in the event
                           such Debtor receives any dividends, interest or
                           distributions on any Investment Property, or any
                           securities or other property upon the merger,
                           consolidation, liquidation or dissolution of any
                           issuer of any Investment Property, then (a) such
                           dividends, interest or distributions and securities
                           or other property shall be included in the definition
                           of Collateral without further action and (b) except
                           with respect to Cash Proceeds, such Debtor shall
                           promptly take all steps, if any, necessary to ensure
                           the validity and perfection, priority and, if
                           applicable, control of the Credit Facility Secured
                           Party or the Secured Party over such Investment
                           Property (including, without limitation, delivery
                           thereof to Secured Party or Credit Facility Secured
                           Party in accordance with the terms of the
                           Intercreditor Agreement to the extent then in effect)
                           and pending any such action such Debtor shall be
                           deemed to hold such dividends, interest,
                           distributions, securities or other property in trust
                           for the benefit of the Secured Party and the Credit
                           Facility Secured Party and shall be segregated from
                           all other property of such Debtor. Notwithstanding
                           the foregoing, so long as no Event of Default shall
                           have occurred and be continuing, Secured Party
                           authorizes each Debtor to retain all ordinary and
                           extraordinary cash dividends and distributions paid
                           in the normal course of business and all payments of
                           principal and interest;

                  (iv)     it shall comply with all of its obligations under any
                           partnership agreement or limited liability company
                           agreement relating to partnership interests or
                           limited liability interests included in the
                           Collateral and shall enforce all of its material
                           rights with respect to any Investment Property, in
                           each case, as appropriate in such Debtor's reasonable
                           business judgment;


                                       15



                  (v)      other than as permitted under the Indenture, it shall
                           not permit any of its Subsidiaries to merge or
                           consolidate unless (i) such Subsidiary creates a
                           security interest by executing a Pledge Joinder
                           pursuant to Section 5.2 that is perfected by a filed
                           financing statement (that is not effective solely
                           under section 9-508 of the UCC) in collateral in
                           which such new debtor has or acquires rights, in each
                           case, to the extent not created or perfected pursuant
                           to this Agreement and any financing statement in
                           effect at such time and (ii) all the outstanding
                           capital stock or other equity interests of the
                           surviving or resulting corporation, limited liability
                           company, partnership or other entity is, upon such
                           merger or consolidation, pledged hereunder; provided
                           that if the surviving or resulting company upon any
                           such merger or consolidation involving an issuer
                           which is a Controlled Foreign Corporation, then such
                           Debtor shall only be required to pledge equity
                           interests to the extent they are not Excluded
                           Collateral; and

                  (vi)     each Debtor consents to the grant by each other
                           Debtor of a security interest in all Investment
                           Property to Secured Party.

         (c) Delivery and Control. Each Debtor agrees that (i) with respect to
any Investment Property in which it has rights as of the Issue Date it shall
comply with the provisions of this Section 4.4(c) on or before the Issue Date;
and (ii) with respect to any Investment Property hereafter acquired by such
Debtor it shall comply with the provisions of this Section 4.4(c) promptly upon
acquiring rights therein. With respect to any Investment Property that is now or
hereafter represented by a certificate or that is an "instrument" (other than
any Investment Property credited to a Securities Account) it shall cause such
certificate or instrument to be delivered to the Credit Facility Secured Party
or the Secured Party (in accordance with the terms of the Intercreditor
Agreement to the extent then in effect), indorsed in blank by an "effective
indorsement" (as defined in Section 8-107 of the UCC), regardless of whether
such certificate constitutes a "certificated security" for purposes of the UCC.
In the event that at any time after the date of this Agreement any partnership
interest or limited liability company interest included in the Collateral is (i)
dealt in or traded on a securities exchange or in a securities market, (ii) by
its terms expressly provides that it is a security governed by Article 8 of the
UCC, (iii) is an investment company security or (iv) is held in a securities
account, the applicable Debtor will promptly notify Secured Party in writing of
such event, and will promptly execute such documents, and do such other acts or
things reasonably requested by Secured Party to deliver to Credit Facility
Secured Party or Secured Party (subject to the terms of the Intercreditor
Agreement to the extent then in effect) control (within the meaning of Article 8
of the UCC) of such partnership interest or limited liability company interest,
as applicable. Each Debtor represents and warrants that none of the events
described in clauses (i), (ii), (iii) or (iv) of the immediately preceding
sentence has occurred and is existing as of the date of this Agreement. No
Debtor will contest in any manner the perfection or priority of Secured Party's
lien on any partnership interest or limited liability company interest included
in the Collateral. With respect to any Investment Property consisting of
Securities Accounts or securities entitlements (as defined in Article 8 of the
UCC), to the extent required under the Credit Facility Documents, it shall use
its reasonable best efforts to cause the securities intermediary maintaining
such Securities Account or securities entitlement to enter into an agreement in
form and substance reasonably satisfactory to Secured Party pursuant to which it
shall, subject to the Intercreditor Agreement to the


                                       16



extent then in effect, agree to comply with the Credit Facility Secured Party's
or the Secured Party's "entitlement orders" without further consent by such
Debtor. With respect to any material Investment Property that is a "Deposit
Account," to the extent required under the Credit Facility Documents, it shall
use its reasonable best efforts to cause the depositary institution maintaining
such account to enter into an agreement in form and substance reasonably
satisfactory to Secured Party, pursuant to which the Credit Agreement Secured
Party or the Secured Party, subject to the terms of the Intercreditor Agreement
to the extent then in effect and any agreements between Secured Party, Credit
Facility Secured Party and the depositary institution, shall have both dominion
and control over such Deposit Account (within the meaning of the common law) and
"control" (as defined in Section 9-104 of the UCC) over such Deposit Account. In
addition to the foregoing, if any issuer of any Investment Property is located
in a jurisdiction outside of the United States, each Debtor shall take such
additional actions within its power or control, including, without limitation,
causing the issuer to register the pledge on its books and records or making
such filings or recordings, in each case as the Secured Party may reasonably
request, under the laws of such issuer's jurisdiction to insure the validity,
perfection and priority of the security interest of Secured Party. Upon the
occurrence of an Event of Default, subject to the terms of the Credit Facility
Documents and the Intercreditor Agreement, in each case, to the extent then in
effect, any applicable laws (including, without limitation) and Section 7
hereof, Secured Party shall have the right to have all or any portion of the
partnership interests or limited liability company interests included in the
Collateral registered in its name or the name of a nominee or agent on the books
of the issuer, to the extent necessary to enforce its rights to receive
distributions with respect thereto or vote such partnership interests and
limited liability company interests; provided that no such registration shall
constitute a transfer of ownership and no Debtor shall be deemed to have waived
its rights under Section 9-610 of the UCC to have such partnership interests or
limited liability company interests sold in a public sale. In addition, Secured
Party (subject to and in accordance with the terms of the Intercreditor
Agreement to the extent then in effect) shall have the right at any time,
without notice to any Debtor, to exchange any certificates or instruments
representing any Investment Property for certificates or instruments of smaller
or larger denominations.

         (d) Voting and Distributions.

                  (i)      So long as no Event of Default shall have occurred
                           and be continuing, subject to applicable laws:

                           (A)      each Debtor shall be entitled to exercise or
                                    refrain from exercising any and all voting
                                    and other consensual rights pertaining to
                                    the Investment Property or any part thereof
                                    for any purpose not inconsistent with the
                                    terms of this Agreement or the Indenture;
                                    and

                           (B)      Secured Party shall promptly execute and
                                    deliver (or cause to be executed and
                                    delivered) to each Debtor all proxies, and
                                    other instruments as such Debtor may from
                                    time to time reasonably request for the
                                    purpose of enabling such Debtor to exercise
                                    the voting and other consensual rights when
                                    and to the extent which it is entitled to
                                    exercise pursuant to clause (A) above; and

                  (ii)     Upon the occurrence and during the continuation of an
                           Event of Default subject to Section 7.6(a),
                           applicable laws and the terms of the Credit Facility
                           Documents and the Intercreditor Agreement, in each
                           case, to the extent then in effect:

                           (A)      all rights of each Debtor to exercise or
                                    refrain from exercising the voting and other
                                    consensual rights which it would otherwise
                                    be entitled to exercise pursuant hereto
                                    shall cease and all such rights shall
                                    thereupon become vested in Secured Party who
                                    shall thereupon have the sole right to
                                    exercise such voting and other consensual
                                    rights; and


                                       17



                           (B)      in order to permit Secured Party to exercise
                                    the voting and other consensual rights which
                                    it may be entitled to exercise pursuant
                                    hereto and to receive all dividends and
                                    other distributions which it may be entitled
                                    to receive hereunder: (1) each Debtor shall
                                    promptly execute and deliver (or cause to be
                                    executed and delivered) to Secured Party all
                                    proxies, dividend payment orders and other
                                    instruments as necessary or as Secured Party
                                    may from time to time reasonably request and
                                    (2) each Debtor acknowledges that Secured
                                    Party may utilize the power of attorney set
                                    forth in Section 6.

                           such Debtor;

                  (vii)    each Debtor uses adequate standards of quality in the
                           manufacture, distribution, and sale of all products
                           sold and in the provision of all services rendered
                           under or in connection with all Trademark Collateral
                           and has taken all action necessary to ensure that all
                           licensees of the Trademark Collateral owned by such
                           Debtor use such adequate standards of quality;

                  (viii)   to the best of such Debtor's knowledge, the conduct
                           of such Debtor's business does not infringe upon any
                           trademark, patent, copyright, trade secret or similar
                           intellectual property right owned or controlled by a
                           third party;

                  (ix)     to the best of such Debtor's knowledge, no third
                           party is infringing upon any material Intellectual
                           Property owned or used by such Debtor;

                  (x)      no settlement or consents, covenants not to sue,
                           nonassertion assurances, or releases have been
                           entered into by any Debtor or to which any Debtor is
                           bound that adversely affects such Debtor's rights to
                           own or use any Intellectual Property material to the
                           business of such Debtor; and

                  (xi)     except in connection with Permitted Liens, each
                           Debtor has not made a previous assignment, sale,
                           transfer or agreement constituting a present or
                           future assignment, sale, transfer or agreement of any
                           Intellectual Property material to the business of
                           such Debtor as currently conducted that has not been
                           terminated or released. There is no effective
                           financing statement or other document or instrument
                           now executed, or on file or recorded in any public
                           office, granting a security interest in or otherwise
                           encumbering any part of such Intellectual Property,
                           other than Permitted Liens and a security interest in
                           favor of Secured Party.

         (b) Covenants and Agreements. Each Debtor hereby covenants and agrees
as follows:

                  (i)      it shall not do any act or omit to do any act whereby
                           any of the Intellectual Property which is material to
                           the business of Debtor may lapse, or become
                           abandoned, dedicated to the public, or unenforceable,
                           or which would adversely affect the validity, grant,
                           or enforceability of the security interest granted
                           therein;

                  (ii)     with respect to any Trademarks which are material to
                           the business of any Debtor, each Debtor shall take
                           all commercially reasonable steps (as determined by
                           such Debtor in the exercise of its reasonable
                           business judgment) to require that licensees of such
                           Trademarks use standards of


                                       19



                           quality consistent with the quality of products sold
                           and services rendered under any of such Trademarks as
                           of the date hereof;

                  (iii)    it shall take all reasonable steps in the United
                           States Patent and Trademark Office and the United
                           States Copyright Office, and, if reasonably requested
                           by the Secured Party, any state registry or any
                           foreign counterpart of the foregoing, to pursue any
                           application and maintain any registration of each
                           Trademark, Patent, and Copyright owned by any Debtor
                           and material to its business which is now or shall
                           become included in the Collateral constituting
                           Intellectual Property (except for such works with
                           respect to which such Debtor has determined in the
                           exercise of its commercially reasonable judgment that
                           it shall not seek registration) including, but not
                           limited to, those items on Schedule 4.5(A), (B) and
                           (D) (as each may be amended or supplemented from time
                           to time);

                  (iv)     in the event that any Intellectual Property owned by
                           or exclusively licensed to any Debtor that is
                           material to such Debtor's business is infringed,
                           misappropriated, or diluted by a third party, such
                           Debtor shall promptly take all reasonable actions (as
                           determined by such Debtor in the exercise of its
                           reasonable business judgment) to seek a remedy for
                           such infringement, misappropriation, or dilution and
                           protect its exclusive rights in such Intellectual
                           Property;

                  (v)      on such periodic basis as Secured Party shall
                           reasonably require and in any event no less
                           frequently than quarterly, not later than the
                           thirtieth day after the end of each quarter, it shall
                           report to Secured Party (i) the filing of any
                           application to register any Intellectual Property
                           with the United States Patent and Trademark Office,
                           the United States Copyright Office, or any state
                           registry or foreign counterpart of the foregoing
                           (whether such application is filed by such Debtor or
                           through any agent, employee, licensee, or designee
                           thereof) and (ii) the registration of any
                           Intellectual Property by any such office, in each
                           case by executing and delivering to Secured Party a
                           completed Pledge Supplement, substantially in the
                           form of Exhibit A attached hereto, together with a
                           Supplement to Schedule 4.5;

                  (vi)     in connection with the actions required pursuant to
                           Section 4.5(b)(v), it shall promptly execute and
                           deliver to Secured Party any document required to
                           acknowledge, confirm, register, record, or perfect
                           Secured Party's interest in any part of the
                           Intellectual Property, whether now owned or hereafter
                           acquired;

                  (vii)    except as permitted under the Indenture, no Debtor
                           shall execute, and there will not be on file in any
                           public office, any financing statement or other
                           document or instruments, except financing statements
                           or other documents or instruments filed or to be
                           filed in favor of creditors under Permitted Liens,
                           Secured Party or the Credit Facility Secured Party,
                           and no Debtor shall create or suffer to exist any
                           Lien upon or with respect to the Intellectual
                           Property, except for Permitted Liens, the Lien
                           created by


                                       20



                           and under this Security Agreement and the other
                           Indenture Documents and the Lien in favor of the
                           Credit Facility Secured Party;

                  (viii)   it shall hereafter use commercially reasonable
                           efforts consistent with industry practice (as
                           determined by such Debtor in the exercise of its
                           reasonable business judgment) so as not to permit the
                           inclusion in any contract to which it hereafter
                           becomes a party of any provision that could
                           reasonably be expected to in any way materially
                           impair or prevent the creation of a security interest
                           in, or the assignment of, such Debtor's rights and
                           interests in any material property included within
                           the definitions of any Intellectual Property acquired
                           under such contracts;

                  (ix)     it shall use proper statutory notice in connection
                           with its use of any material Intellectual Property;
                           and

                  (x)      it shall continue to collect, at its own expense, all
                           amounts due or to become due to such Debtor in
                           respect of the Intellectual Property or any portion
                           thereof as it deems advisable in its reasonable
                           business judgment. In connection with such
                           collections, each Debtor may take such action as such
                           Debtor may deem reasonably necessary or advisable to
                           enforce collection of such amounts. Notwithstanding
                           the foregoing, subject to the Credit Facility
                           Documents and the Intercreditor Agreement as then in
                           effect, Secured Party shall have the right at any
                           time following an Event of Default, to notify, or
                           require any Debtor to notify, any obligors with
                           respect to any such amounts of the existence of the
                           security interest created hereby.

         4.6 COMMERCIAL TORT CLAIMS.

         (a) Representations and Warranties. Each Debtor hereby represents and
warrants, on the Issue Date, that Schedule 4.6 sets forth all Commercial Tort
Claims of each Debtor against third parties; and

         (b) Covenants and Agreements. Each Debtor hereby covenants and agrees
that with respect to any Commercial Tort Claim of it against third parties
hereafter arising it shall deliver to Secured Party a completed Pledge
Supplement, substantially in the form of Exhibit A attached hereto, together
with a Supplement to Schedule 4.6, identifying such new Commercial Tort Claims.

5.       FURTHER ASSURANCES; ADDITIONAL DEBTORS.

         5.1 FURTHER ASSURANCES.

         (a) Each Debtor agrees that from time to time, at the expense of such
Debtor, it shall promptly execute and deliver all further instruments and
documents, and take all further action, that may be necessary or reasonably
requested in order to create and/or maintain the validity, perfection or
priority of and protect any security interest granted or purported to be granted
hereby or to enable Secured Party to exercise and enforce its rights and
remedies hereunder with respect to any Collateral, in each case, to


                                       21



the extent required hereunder and consistent with its obligations under the
Credit Facility Documents. Without limiting the generality of the foregoing,
each Debtor shall:

                  (i)      execute and file such financing or continuation
                           statements, or amendments thereto, and execute and
                           deliver such other agreements, instruments,
                           endorsements, powers of attorney or notices, as may
                           be necessary or desirable, in order to perfect and
                           preserve the security interests granted or purported
                           to be granted hereby;

                  (ii)     take all actions necessary to ensure the recordation
                           of appropriate evidence of the liens and security
                           interest granted hereunder in the Intellectual
                           Property with any intellectual property registry in
                           which said Intellectual Property is registered or in
                           which an application for registration is pending
                           including, without limitation, the United States
                           Patent and Trademark Office, the United States
                           Copyright Office, the various Secretaries of State,
                           and the foreign counterparts on any of the foregoing;

                  (iii)    at any reasonable time, upon request by Secured
                           Party, exhibit the Collateral to and allow inspection
                           of the Collateral by Secured Party, or persons
                           designated by Secured Party; and

                  (iv)     appear in and defend any action or proceeding that
                           may affect such Debtor's title to or Secured Party's
                           security interest in all or any part of the
                           Collateral.

         (b) Each Debtor hereby authorizes Secured Party to file a Record or
Records, including, without limitation, financing or continuation statements,
and amendments thereto, in all jurisdictions and with all filing offices as are
necessary or advisable to perfect the security interest granted to Secured Party
herein. Such financing statements may describe the Collateral in the same manner
as described herein or may contain an indication or description of collateral
that describes such property in any other manner as is necessary, advisable or
prudent to ensure the perfection of the security interest in the Collateral
granted to Secured Party herein. Each Debtor shall, if requested by the Secured
Party, furnish to Secured Party from time to time statements and schedules
further identifying and describing the Collateral, all in reasonable detail.

         (c) Each Debtor hereby authorizes Secured Party to modify this
Agreement after obtaining such Debtor's approval of or signature to such
modification by amending Schedule 4.5 to include reference to any right, title
or interest in any existing Intellectual Property or any Intellectual Property
acquired or developed by any Debtor after the execution hereof or to delete any
reference to any right, title or interest in any Intellectual Property in which
any Debtor no longer has or claims any right, title or interest.

         (d) The Issuer covenants and agrees that, upon the satisfaction or
termination of that certain Credit Line Deed of Trust, executed by the Issuer
and recorded in the land records of Loudoun County, Virginia on March 5, 2002,
in Deed Book 2125, Page 2255 (the "SENIOR DEED OF TRUST"), and all indebtedness
and other rights or interests (collectively, the "SENIOR INDEBTEDNESS")
evidenced or created by the Credit Facility Documents being Fully Paid (as
defined in the Intercreditor Agreement), the lien created by that certain Deed
of Trust and Security Agreement, dated as of the date hereof (the "DEED OF
TRUST"), executed by the Issuer, as grantor, in favor of Walker Title & Escrow
Company, Inc., a Virginia corporation, as trustee, for the benefit of Secured
Party, as beneficiary, shall be a first priority


                                       22



lien on the "Secured Property" (as defined in the Deed of Trust), and the value
of such lien shall be the then fair market value of the Secured Property;
provided, however, that the foregoing provisions of this Section 5.1(d) shall
not become effective in the event that the Senior Deed of Trust is replaced upon
the satisfaction or termination of the Senior Deed of Trust with a new deed of
trust on the same property securing indebtedness incurred pursuant to any
refinancing or replacement of the Credit Facility Documents permitted under the
Indenture; provided, further, that, notwithstanding the Deed of Trust becoming a
first priority lien at any time pursuant to this Section 5.1(d), in connection
with any subsequent refinancing or replacement of Credit Facility indebtedness
permitted under the Indenture, the Secured Party shall, if requested by the
Issuer, subordinate its lien on the Secured Property to any such lien granted in
favor of the Credit Facility Secured Party and shall take such actions as may be
reasonably requested by the Issuer to evidence such subordination.

         (e) Upon the Deed of Trust becoming a first priority Lien on the
Secured Property and at the reasonable request of Secured Party, the Issuer, at
its sole cost and expense, shall have delivered to Secured Party the following
documents:

                  (i)      one or more endorsements to the mortgagee policies of
                           title insurance delivered to Secured Party in
                           connection with the Deed of Trust insuring that,
                           after giving effect to such satisfaction, (A) the
                           insured amounts under such mortgagee policies is
                           increased to the then fair market value of the
                           Secured Property insured thereunder (together with
                           any updated endorsements as may be required pursuant
                           to such increased insured amount, including without
                           limitation, updated tie-in endorsements), and (B)
                           that each such policy is in full force and effect and
                           unaffected by such satisfaction of the Senior Deed of
                           Trust, and

                  (ii)     any other documents, instruments or deliveries as may
                           reasonably be required by Secured Party, including,
                           without limitation, any amendments or modifications
                           to the Deed of Trust.

         (f) If, at any time, the Trustee obtains possession or control of items
of Collateral, upon a replacement or refinancing of the Credit Agreement, the
Trustee shall deliver such items to the Replacement Credit Facility Secured
Party if such Replacement Credit Facility Secured Party has entered into an
intercreditor agreement as contemplated by Section 7.1(i) of the Indenture.

         (g) Secured Party acknowledges that Issuer is required under the Credit
Facility Documents to enter into a new control agreement with respect to a
Deposit Account or a Securities Account within 30 days following the date hereof
and, in connection therewith, agrees to reasonably cooperate with the Debtors
and the Credit Facility Secured Party to implement the control agreement
contemplated by Section 4.4(c) hereof within such time period.

         5.2 ADDITIONAL DEBTORS.

         From time to time subsequent to the date hereof, additional Guarantors
may become Additional Debtors pursuant to the terms of the Indenture, by
executing a Pledge Joinder substantially in the form attached hereto as Exhibit
B. Upon delivery of any such counterpart agreement to Secured Party, notice of
which is hereby waived by Debtors, (a) each Additional Debtor shall be a Debtor
and shall be as fully a party hereto as if such Additional Debtor were an
original signatory hereto and (b) the supplemental schedules thereto shall be
incorporated into and become a part of and supplement the respective schedules
to this Agreement; and each reference to such Schedules shall mean and be a
reference to such Schedules as supplemented pursuant to each Pledge Supplement.
Each Debtor expressly agrees that its obligations


                                       23



arising hereunder shall not be affected or diminished by the addition or release
of any other Debtor hereunder, nor by any election of Secured Party not to cause
any Subsidiary of Issuer to become an Additional Debtor hereunder. This
Agreement shall be fully effective as to any Debtor that is or becomes a party
hereto regardless of whether any other Person becomes or fails to become or
ceases to be a Debtor hereunder.

6.       ATTORNEY-IN-FACT.

         6.1 POWER OF ATTORNEY.

         Each Debtor hereby irrevocably appoints Secured Party (such appointment
being coupled with an interest) as such Debtor's attorney-in-fact, with full
authority in the place and stead of such Debtor and in the name of such Debtor,
Secured Party or the Credit Facility Secured Party (subject to the Intercreditor
Agreement to the extent then in effect), from time to time in its discretion to
take any action permitted under the Credit Facility Documents and to execute any
instrument that it may deem reasonably necessary or advisable to accomplish the
purposes of this Agreement (subject to the Intercreditor Agreement to the extent
then in effect), including, without limitation, the following:

                  (a) upon the occurrence and during the continuance of any
Event of Default, to obtain and adjust insurance required to be maintained by
such Debtor pursuant to the Indenture;

                  (b) upon the occurrence and during the continuance of any
Event of Default, to ask for, demand, collect, sue for, recover, compound,
receive and give acquittance and receipts for moneys due and to become due under
or in respect of any of the Collateral;

                  (c) upon the occurrence and during the continuance of any
Event of Default, to receive, endorse and collect any drafts or other
instruments, documents and chattel paper in connection with clause (b) above,
subject in all respects to the rights of any lender under the Credit Agreement
to receive, endorse and collect the same;

                  (d) upon the occurrence and during the continuance of any
Event of Default, to file any claims or take any action or institute any
proceedings necessary or desirable for the collection of any of the Collateral
or otherwise to enforce the rights of Secured Party with respect to any of the
Collateral;

                  (e) to prepare and file any UCC financing statements against
such Debtor as debtor;

                  (f) to prepare, sign, and file for recordation in any
intellectual property registry, appropriate evidence of the lien and security
interest granted herein in the Intellectual Property in the name of such Debtor
as assignor;

                  (g) to take or cause to be taken all actions necessary to
perform or comply or cause performance or compliance with the terms of this
Agreement, including, without limitation, access to pay or discharge taxes or
Liens (other than Permitted Liens) levied or placed upon or threatened against
the Collateral, the legality or validity thereof and the amounts necessary to
discharge the same, any such payments made by Secured Party to become
obligations of such Debtor to Secured Party, due and payable immediately without
demand; and

                  (h) upon the occurrence and during the continuance of any
Event of Default and subject to the provisions of the UCC, generally to sell,
transfer, pledge, make any agreement with respect to or otherwise deal with any
of the Collateral as fully and completely as though Secured Party were the
absolute owner thereof for all purposes, and to do, at Secured Party's option
and such Debtor's expense, at


                                       24



any time or from time to time, all acts and things necessary to protect,
preserve or realize upon the Collateral and Secured Party's security interest
therein in order to effect the intent of this Agreement, all as fully and
effectively as such Debtor might do.

         6.2 NO DUTY ON THE PART OF SECURED PARTY.

         The powers conferred on Secured Party hereunder are solely to protect
the interests of Secured Party in the Collateral and shall not impose any duty
upon Secured Party to exercise any such powers. Secured Party shall be
accountable only for amounts that it actually receives as a result of the
exercise of such powers, and neither it nor any of its officers, directors,
employees or agents shall be responsible to any Debtor for any act or failure to
act hereunder, except for their own gross negligence or willful misconduct.

7.       REMEDIES.

         7.1 GENERALLY.

         (a) If any Event of Default shall have occurred and be continuing,
subject to applicable laws and the provisions of the Intercreditor Agreement to
the extent then in effect, Secured Party may exercise in respect of the
Collateral, in addition to all other rights and remedies provided for herein or
otherwise available to it at law or in equity, all the rights and remedies of
Secured Party on default under the UCC (whether or not the UCC applies to the
affected Collateral) to collect, enforce or satisfy any Secured Obligations then
owing, whether by acceleration or otherwise, and also may pursue any of the
following separately, successively or simultaneously:

                  (i)      require any Debtor to, and each Debtor hereby agrees
                           that it shall at its expense and promptly upon
                           request of Secured Party forthwith, assemble all or
                           part of the Collateral as directed by Secured Party
                           and make it available to Secured Party at a place to
                           be designated by Secured Party that is reasonably
                           convenient to both parties;

                  (ii)     enter onto the property where any Collateral is
                           located and take possession thereof with or without
                           judicial process;

                  (iii)    prior to the disposition of the Collateral, store,
                           process, repair or recondition the Collateral or
                           otherwise prepare the Collateral for disposition in
                           any manner to the extent Secured Party deems
                           appropriate;

                  (iv)     without notice except as specified below or under the
                           UCC, sell, assign, lease, license (on an exclusive or
                           nonexclusive basis) or otherwise dispose of the
                           Collateral or any part thereof in one or more parcels
                           at public or private sale, at any of Secured Party's
                           offices or elsewhere, for cash, on credit or for
                           future delivery, at such time or times and at such
                           price or prices and upon such other terms as Secured
                           Party may deem commercially reasonable; and

                  (v)      subject to the terms of the Intercreditor Agreement,
                           apply the balance from any Deposit Account or
                           instruct the bank at which any Deposit



                                       25



                           Account is maintained to pay the balance of any
                           Deposit Account to or for the benefit of Secured
                           Party.

         (b) Secured Party may be a purchaser of any or all of the Collateral at
any public or private (to the extent permitted by applicable law) sale in
accordance with the UCC and Secured Party, as Secured Party for and
representative of the Holders, shall be entitled, for the purpose of bidding and
making settlement or payment of the purchase price for all or any portion of the
Collateral sold at any such sale made in accordance with the UCC, to use and
apply any of the Secured Obligations as a credit on account of the purchase
price for any Collateral payable by Secured Party at such sale. Each purchaser
at any such sale shall hold the property sold absolutely free from any claim or
right on the part of any Debtor, and each Debtor hereby waives (to the extent
permitted by applicable law) all rights of redemption, stay and/or appraisal
which it now has or may at any time in the future have under any rule of law or
statute now existing or hereafter enacted. Each Debtor agrees that, to the
extent notice of sale shall be required by law, at least ten (10) days notice to
such Debtor 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. 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. Each Debtor agrees that it would not be commercially unreasonable
for Secured Party to dispose of the Collateral or any portion thereof by using
Internet sites that provide for the auction of assets of the types included in
the Collateral or that have the reasonable capability of doing so, or that match
buyers and sellers of assets. Each Debtor hereby waives any claims against
Secured Party arising by reason of the fact that the price at which any
Collateral may have been sold at such a private sale was less than the price
which might have been obtained at a public sale, even if Secured Party accepts
the first offer received and does not offer such Collateral to more than one
offeree. If the proceeds of any sale or other disposition of the Collateral are
insufficient to pay all the Secured Obligations, each Debtor shall be liable for
the deficiency and the fees of any attorneys employed by Secured Party to
collect such deficiency. Each Debtor further agrees that a breach of any of the
covenants contained in this Section will cause irreparable injury to Secured
Party, that Secured Party has no adequate remedy at law in respect of such
breach and, as a consequence, that each and every covenant contained in this
Section shall be specifically enforceable against such Debtor, and such Debtor
hereby waives and agrees not to assert any defenses against an action for
specific performance of such covenants except for a defense that no default has
occurred giving rise to the Secured Obligations becoming due and payable prior
to their stated maturities. Nothing in this Section shall in any way alter the
rights of Secured Party hereunder.

         (c) Secured Party may sell the Collateral without giving any warranties
as to the Collateral. Secured Party may specifically disclaim or modify any
warranties of title or the like. This procedure will not be considered to
adversely affect the commercial reasonableness of any sale of the Collateral.

         (d) If Secured Party sells any of the Collateral on credit, the Secured
Obligations will be credited only with payments actually made by the purchaser
and received by Secured Party and applied to the indebtedness of the purchaser.
In the event the purchaser fails to pay for the Collateral, Secured Party may
resell the Collateral, subject to applicable laws.

         (e) Secured Party shall have no obligation to marshal any of the
Collateral.

         (f) Subject to the Credit Facility Documents and the Intercreditor
Agreement, all amounts and proceeds (including checks and other instruments)
received by any Debtor in respect of amounts due to such Debtor in respect of
the Collateral or any portion thereof following the occurrence


                                       26



and during the continuance of an Event of Default shall be received in trust for
the benefit of Secured Party or the Credit Facility Secured Party, shall be
segregated from other funds of such Debtor and shall be forthwith paid over or
delivered to Secured Party in the same form as so received (with any necessary
endorsement) to be held as cash Collateral and applied as provided by Section
7.5 following the occurrence and during the continuance of an Event of Default.
Upon demand from Secured Party, Debtors shall not adjust, settle or compromise
the amount or payment of any such amount or release wholly or partly any obligor
with respect thereto or allow any credit or discount thereon.

         7.2 APPLICATION OF PROCEEDS.

         Except as expressly provided elsewhere in this Agreement and in the
Intercreditor Agreement to the extent then in effect, all proceeds received by
Secured Party in respect of any sale, any collection from, or other realization
upon all or any part of the Collateral shall be applied in full or in part by
Secured Party against the Secured Obligations in the following order of
priority: first, to the payment of all costs and expenses of such sale,
collection or other realization, including reasonable compensation to Secured
Party and its agents and counsel, and all other expenses, liabilities and
advances made or incurred by Secured Party in connection therewith, and all
amounts for which Secured Party is entitled to indemnification hereunder and all
advances made by Secured Party hereunder for the account of the applicable
Debtor, and to the payment of all costs and expenses paid or incurred by Secured
Party in connection with the exercise of any right or remedy hereunder or under
the Indenture, all in accordance with the terms hereof or thereof; second, to
the extent of any excess of such proceeds, to the payment of all other Secured
Obligations for the ratable benefit of the Holders; and third, to the extent of
any excess of such proceeds, to the payment to or upon the order of such Debtor
or to whomsoever may be lawfully entitled to receive the same as a court of
competent jurisdiction may direct.

         7.3 INVESTMENT PROPERTY.

         Each Debtor recognizes that, by reason of certain prohibitions
contained in the Securities Act and applicable state securities laws, Secured
Party may be compelled, with respect to any sale of all or any part of the
Investment Property conducted without prior registration or qualification of
such Investment Property under the Securities Act and/or such state securities
laws, to limit purchasers to those who will agree, among other things, to
acquire the Investment Property for their own account, for investment and not
with a view to the distribution or resale thereof and to comply with applicable
laws. Each Debtor acknowledges that any such sale may be at prices and on terms
less favorable than those obtainable through a sale without such restrictions
(including a public offering made pursuant to a registration statement under the
Securities Act) and each Debtor agrees that any such sale shall not be deemed to
have not been made in a commercially reasonable manner by reason of such
circumstances and that Secured Party shall have no obligation to engage in
public sales and no obligation to delay the sale of any Investment Property for
the period of time necessary to permit the issuer thereof to register it for a
form of public sale requiring registration under the Securities Act or under
applicable state securities laws, even if such issuer would, or should, agree to
so register it. If Secured Party determines to exercise its right to sell any or
all of the Investment Property, upon written request, each Debtor shall and
shall cause each issuer of any stock included in the Collateral to be sold
hereunder, each partnership and each limited liability company from time to time
to furnish to Secured Party all such information as Secured Party may request in
order to determine the number and nature of interests, shares or other
instruments included in the Investment Property which may be sold by Secured
Party in exempt transactions under the Securities Act and the rules and
regulations of the Securities and Exchange Commission thereunder, as the same
are from time to time in effect.


                                       27



         7.4 INTELLECTUAL PROPERTY.

         (a) Anything contained herein to the contrary notwithstanding, upon the
occurrence and during the continuation of an Event of Default and subject to the
Credit Facility Documents and the Intercreditor Agreement to the extent then in
effect:

                  (i)      Secured Party shall have the right (but not the
                           obligation) to bring suit or otherwise commence any
                           action or proceeding in the name of any Debtor,
                           Secured Party or otherwise, in Secured Party's sole
                           discretion, to enforce any Intellectual Property
                           which is material to any Debtor's business, in which
                           event such Debtor shall, at the request of Secured
                           Party, do any and all lawful acts and execute any and
                           all documents required by Secured Party in aid of
                           such enforcement and such Debtor shall promptly, upon
                           demand, reimburse and indemnify Secured Party as
                           provided in Section 10 hereof in connection with the
                           exercise of its rights under this Section, and, to
                           the extent that Secured Party shall elect not to
                           bring suit to enforce any Intellectual Property which
                           is material to any Debtor's business as provided in
                           this Section, each Debtor agrees to use all
                           reasonable measures, whether by action, suit,
                           proceeding or otherwise, to prevent the infringement
                           of any such Intellectual Property by others and for
                           that purpose agrees to diligently maintain any
                           action, suit or proceeding against any Person so
                           infringing as shall be necessary to prevent such
                           infringement;

                  (ii)     upon written demand from Secured Party, each Debtor
                           shall grant, assign, convey or otherwise transfer to
                           Secured Party all of such Debtor's right, title and
                           interest in and to the Intellectual Property and
                           shall execute and deliver to Secured Party such
                           documents as are necessary or appropriate to carry
                           out the intent and purposes of this Agreement;

                  (iii)    each Debtor agrees that such an assignment and/or
                           recording shall be applied to reduce the Secured
                           Obligations outstanding only to the extent that
                           Secured Party receives cash proceeds in respect of
                           the sale of, or other realization upon, the
                           Intellectual Property; and

                  (iv)     Secured Party shall have the right to notify, or
                           require each Debtor to notify, any obligors with
                           respect to amounts due or to become due to such
                           Debtor in respect of the Intellectual Property, of
                           the existence of the security interest created
                           herein, to direct such obligors to make payment of
                           all such amounts directly to Secured Party, and, upon
                           such notification and at the expense of such Debtor,
                           to enforce collection of any such amounts and to
                           adjust, settle or compromise the amount or payment
                           thereof, in the same manner and to the same extent as
                           such Debtor might have done.

         (b) If (i) an Event of Default shall have occurred and, by reason of
cure, waiver, modification, amendment or otherwise, no longer be continuing,
(ii) no other Event of Default shall have occurred and be continuing, (iii) an
assignment or other transfer to Secured Party of any rights, title and interests
in and to the Intellectual Property shall have been previously made and shall
have become


                                       28



absolute and effective, and (iv) the Secured Obligations shall not have become
immediately due and payable, upon the written request of any Debtor, Secured
Party shall promptly execute and deliver to such Debtor, at such Debtor's sole
cost and expense, such assignments or other transfer as may be necessary to
reassign to such Debtor any such rights, title and interests as may have been
assigned to Secured Party as aforesaid, subject to any disposition thereof that
may have been made by Secured Party; provided, after giving effect to such
reassignment, Secured Party's security interest granted pursuant hereto, as well
as all other rights and remedies of Secured Party granted hereunder, shall
continue to be in full force and effect; and provided further, the rights, title
and interests so reassigned shall be free and clear of any Liens granted by or
on behalf of Secured Party.

         (c) Solely for the purpose of enabling Secured Party to exercise rights
and remedies under this Section 7 and at such time as Secured Party shall be
lawfully entitled to exercise such rights and remedies, each Debtor hereby
grants to Secured Party, to the extent it has the right to do so (including,
without limitation, pursuant to the Credit Facility Documents and the
Intercreditor Agreement to the extent then in effect), an irrevocable,
nonexclusive license (exercisable without payment of royalty or other
compensation to such Debtor), subject, in the case of Trademarks, to sufficient
rights to quality control and inspection in favor of such Debtor to avoid the
risk of invalidation of said Trademarks, to use, operate under, license, or
sublicense any Intellectual Property now owned or hereafter acquired by such
Debtor, and wherever the same may be located.

         7.5 CASH PROCEEDS.

         Subject to the Credit Facility Documents and the Intercreditor
Agreement as then in effect, in addition to the rights of Secured Party
specified in Section 4.3 with respect to payments of Accounts, Cash Proceeds
shall be held by such Debtor in trust for Secured Party, segregated from other
funds of such Debtor, and shall, forthwith upon receipt by such Debtor, unless
otherwise provided pursuant to Section 4.4, be turned over to Secured Party in
the exact form received by such Debtor (duly indorsed by such Debtor to Secured
Party, if required). Subject to the Intercreditor Agreement as then in effect,
if an Event of Default shall have occurred and be continuing, any Cash Proceeds
received by Secured Party (whether from a Debtor or otherwise) may, in the sole
discretion of Secured Party, (i) be held by Secured Party for the ratable
benefit of the Holders, as collateral security for the Secured Obligations
(whether matured or unmatured) and/or (ii) then or at any time thereafter may be
applied by Secured Party against the Secured Obligations then due and owing.

8.       CONTINUING SECURITY INTEREST; TRANSFER OF NOTES.

         This Agreement shall create a continuing security interest in the
Collateral and shall remain in full force and effect until the payment in full
of all Secured Obligations, be binding upon each Debtor, its successors and
assigns (except to the extent otherwise provided in the Indenture), and inure,
together with the rights and remedies of Secured Party hereunder, to the benefit
of Secured Party and its successors, transferees and assigns. Without limiting
the generality of the foregoing, but subject to the terms of the Indenture, any
Holder may assign or otherwise transfer any Note held by it to any other Person,
and such other Person shall thereupon become vested with all the benefits in
respect thereof granted to Holders herein or otherwise. Upon the payment in full
of all Secured Obligations, the security interest granted hereby shall terminate
hereunder and of record and all rights to the Collateral granted hereunder shall
revert to Debtors. Upon the sale or other disposition of any Collateral

9.       STANDARD OF CARE; SECURED PARTY MAY PERFORM.

         The powers conferred on Secured Party hereunder are solely to protect
its interest in the Collateral and shall not impose any duty upon it to exercise
any such powers. Except for the exercise of reasonable care in the custody of
any Collateral in its possession and the accounting for moneys actually received
by it hereunder, Secured Party shall have no duty as to any Collateral or as to
the taking of any necessary steps to preserve rights against prior parties or
any other rights pertaining to any Collateral. Secured Party shall be deemed to
have exercised reasonable care in the custody and preservation of Collateral in
its possession if such Collateral is accorded treatment substantially equal to
that which Secured Party accords its own property. Neither Secured Party nor any
of its directors, officers, employees or agents shall be liable for failure to
demand, collect or realize upon all or any part 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 any Debtor or otherwise. If any Debtor
fails to perform any agreement contained herein, Secured Party may itself
perform, or cause performance of, such agreement, and the expenses of Secured
Party incurred in connection therewith shall be payable by each Debtor under
Section 11.2 hereof.

10.      INDEMNITY AND EXPENSES.
