Interest Rate Guaranteed Parties (collectively, the "Guaranteed Parties").

<PAGE>

     1.   Guaranty.
          --------

          (a) Each Guarantor unconditionally and irrevocably guarantees the
prompt payment when due, whether at stated maturity, upon acceleration or
otherwise, and at all times thereafter, of all the unpaid principal of and
interest on the Loans (including, without limitation, interest accruing after
the maturity of the Loans and interest accruing after the filing of any petition
in bankruptcy, or the commencement of any insolvency, reorganization or like
proceeding, relating to any Credit Party, whether or not a claim for post-filing
or post-petition interest is allowed in such proceeding) and all other
obligations and liabilities of the Borrower to the Administrative Agent, any
Bank or the Issuing Bank (or in the case of any Interest Rate Protection
Agreement, any Affiliate of any Bank), whether direct or indirect, absolute or
contingent, due or to become due, or now existing or hereafter incurred, that
may arise under, out of, or in connection with the Credit Agreement, any other
Loan Document, any Letter of Credit, any Interest Rate Protection Agreement
entered into with any Bank (or any Affiliate of any Bank), or any other document
made, delivered or given in connection with any of the foregoing, whether on
account of principal, interest, Guaranty Obligations, reimbursement obligations,
fees, indemnities, costs, expenses (including, without limitation, all fees,
charges and disbursements of counsel to the Administrative Agent or to any Bank
that are required to be paid by the Borrower  pursuant to any Loan Document) or
otherwise (collectively, all of the foregoing are referred to herein as the
"Guaranteed Obligations").
 ----------------------

          (b) In addition to the Guaranteed Obligations, each Guarantor further
agrees to pay any and all reasonable costs and expenses (including reasonable
fees and disbursements of counsel) incurred by any Guaranteed Party in enforcing
any rights under this Guaranty together with any accrued but unpaid interest on
the Guaranteed Obligations (including, without limitation, interest which, but
for the filing of a petition of bankruptcy with respect to the Borrower, would
have accrued on the Guaranteed Obligations), which agreement shall survive
termination of this Guaranty.

          (c) Each Guarantor understands and confirms that the Guaranteed
Parties may enforce this Guaranty up to the full amount of the Guaranteed
Obligations against any Guarantor without proceeding against the Borrower or any
other Person, any security for the Guaranteed Obligations, or under any other
guaranty covering all or a portion of the Guaranteed Obligations.

          (d) Notwithstanding anything in this Guaranty to the contrary, the
obligations of each Guarantor under this Guaranty shall be limited to a maximum
aggregate amount equal to the largest amount that would not render such
Guarantor's obligations hereunder subject to avoidance as a fraudulent transfer
or fraudulent conveyance under Section 548 of Title 11 of the United States Code
or any applicable provisions of comparable state law (collectively, the
"Fraudulent Transfer Laws"), in each case after giving effect to all other
 ------------------------
liabilities of such Guarantor, contingent or otherwise, that are relevant under
the Fraudulent Transfer Laws (specifically excluding, however, any liabilities
of such Guarantor in respect of intercompany Indebtedness to the Borrower or any
Subsidiary or Affiliate of the Borrower to the extent that such Indebtedness
would be discharged in an amount equal to the amount paid by such Guarantor
hereunder) and after giving effect as assets to the value (as determined under
the applicable provisions of the Fraudulent Transfer Laws) of any rights to
subrogation, reimbursement or contribution of such Guarantor pursuant to (i)
applicable law, or (ii) any

                                       2
<PAGE>

agreement providing for rights of subrogation, reimbursement or contribution in
favor of such Guarantor, or for an equitable allocation among such Guarantor,
the Borrower and/or any other Person of obligations arising under guaranties by
such Persons.

     2.   No Release.  Each Guarantor agrees that the Guaranteed Obligations may
          ----------
be extended, renewed or otherwise modified, in whole or in part, without any
notice to or further assent from it, and that such Guarantor will remain bound
by this Guaranty notwithstanding any extension, renewal or other modification of
any Guaranteed Obligation.

     3.   Waiver of Notices.  Each Guarantor waives notice of the acceptance of
          ------------------
this Guaranty, presentment, protest, notice, dishonor or default, demand for
payment and any other notices to which Guarantor might otherwise be entitled.

     4.   Obligations Absolute.  The obligations of each Guarantor under this
          --------------------
Guaranty are those of a primary obligor, and not merely a surety, are
independent of the obligations of the Guaranteed Parties, and shall not be
affected by any:

          (a) change in the manner, place or terms of payment of (including the
currency thereof), and/or change or extension of the time of payment of, or
renewal or modification of, any of the Guaranteed Obligations, any security or
guarantee therefor, or any liability incurred directly or indirectly in respect
thereof; provided, that this Guaranty shall apply to the Guaranteed Obligations
as so changed, extended, renewed or modified;

          (b) sale, exchange, release, surrender, realization upon, failure to
perfect any security interest in, or other alteration in any manner and in any
order of any property by whomsoever at any time pledged or mortgaged to secure,
or howsoever securing, the Guaranteed Obligations or any liabilities (including
any of those hereunder) incurred directly or indirectly in respect thereof or
hereof and for offset thereagainst;

          (c) settlement or compromise of any of the Guaranteed Obligations, any
security or guarantee therefor or any liability (including any of those
hereunder) incurred directly or indirectly in respect thereof or hereof, or
subordination of the payment of all or any part thereof to the payment of any
liability (whether due or not) of the Borrower;

          (d) actions or failures to act in any manner referred to in this
Guaranty which may deprive such Guarantor of its right to subrogation against
the Borrower to recover full indemnity for any payments made pursuant to this
Guaranty;

          (e) failure of any Guaranteed Party to assert any claim or demand or
to enforce any right or remedy against the Borrower or any guarantor or any
successor thereto under the provisions of the Credit Agreement, any other Loan
Document or any other agreement or otherwise; or

          (f) rescission, waiver, extension, renewal, amendment or modification
of any of the terms or provisions of the Credit Agreement, any other Loan
Document, any guarantee or any instrument or agreement executed pursuant
thereto.

                                       3
<PAGE>

     5.   Guaranty of Payment and Performance.  This Guaranty constitutes a
          -----------------------------------
guarantee of payment and performance when due and not of collection and each
Guarantor waives any right to require that any resort be had by any Guaranteed
Party to the Borrower, any other guarantor, any property by whomsoever at any
time pledged or mortgaged to secure, or howsoever securing, the Guaranteed
Obligations or any balance of any deposit account or credit on the books of any
Guaranteed Party in favor of the Borrower or any other Person.

     6.   Unenforceability of Obligations.  The obligations of each Guarantor
          -------------------------------
under this Guaranty shall not be subject to any reduction, limitation,
impairment or termination for any reason (other than by payment and performance
in full of the Guaranteed Obligations and termination of all Commitments under
the Credit Agreement, and except as limited in Section 1(d) of this Guaranty)
and shall not be subject to any defense or setoff, counterclaim, recoupment or
termination whatsoever by reason of the invalidity, illegality or
unenforceability of any of the Guaranteed Obligations, discharge of the Borrower
from any of the Guaranteed Obligations in a bankruptcy or similar proceeding or
otherwise (other than by payment and performance in full of the Guaranteed
Obligations and termination of all Commitments under the Credit Agreement, and
except as limited in Section 1(d) of this Guaranty).

     7.   Set-Off.  In addition to any rights now or hereafter granted under
          -------
applicable law (including, without limitation, Section 151 of the New York
Debtor and Creditor Law) and not by way of limitation of any such rights, upon
the occurrence of any Event of Default, each Guaranteed Party is hereby
authorized at any time or from time to time, without notice to any Guarantor or
to any other Person, any such notice being expressly waived, to the extent
permitted by applicable law, to set off and to appropriate and apply any and all
deposits (general or special) and any other indebtedness at any time held or
owing by such Guaranteed Party to or for the credit or the account of any
Guarantor, against and on account of the obligations and liabilities of such
Guarantor to such Guaranteed Party under this Guaranty, irrespective of whether
or not such Guaranteed Party shall have made any demand hereunder and although
said obligations, liabilities, deposits or claims, or any of them, shall be
contingent or unmatured.

     8.   Reinstatement. This Guaranty shall continue to be effective and, if
          -------------
cancelled or otherwise terminated shall be reinstated, if at any time any
payment, or any part thereof, of principal of, interest on or any other amount
with respect to any Guaranteed Obligation is rescinded or must otherwise be
restored by any Guaranteed Party or any other Person upon the bankruptcy or
reorganization of the Borrower or any other Person or otherwise.   If claim is
ever made upon any Guaranteed Party for repayment or recovery of any amount or
amounts received in payment or on account of any of the Guaranteed Obligations
and any of the Guaranteed Parties repays all or part of said amount by reason of
(a) any judgment, decree or order of any court or administrative body having
jurisdiction over such Guaranteed Party or any of its property, or (b) any
settlement or compromise of any such claim effected by such Guaranteed Party
with any such claimant (including the Borrower), then and in such event each
Guarantor jointly and severally agrees that any such judgment, decree, order,
settlement or compromise shall be binding upon it, notwithstanding any
revocation, termination or cancellation hereof or of the Credit Agreement, any
other Loan Document or any other instrument evidencing any liability of the
Borrower, and such Guarantor shall be and remain liable to such Guaranteed Party
hereunder for the amount so repaid or recovered to the same extent as if such
amount had never originally been received by any such Guaranteed Party.

                                       4
<PAGE>

     9.   No Subrogation.  Notwithstanding any payment or payments by any
          --------------
Guarantor hereunder or any set-off or application of funds of any Guarantor by
any Guaranteed Party, no Guarantor shall be entitled to be subrogated to any of
the rights of any Guaranteed Party against the Borrower or guarantee or right of
offset held by any Guaranteed Party of the payment of the Guaranteed
Obligations, nor shall any Guarantor seek to be entitled to seek any
reimbursement or contribution from the Borrower or any other Guarantor in
respect of payments made by such Guarantor hereunder, until all amounts owing to
the Guaranteed Parties by the Borrower on account of the Guaranteed Obligations
are indefeasibly paid in full in cash.  If any amount shall be paid to any
Guarantor on account of the subrogation rights at any time when all of the
Guaranteed Obligations of the Borrower have not been indefeasibly paid in full
in cash, such amount shall be held by such Guarantor in trust for the Guaranteed
Parties, segregated from other funds of such Guarantor, and shall, immediately
upon receipt by such Guarantor, be turned over to the Administrative Agent in
the exact form received by such Guarantor (duly endorsed by such Guarantor to
the Administrative Agent, if required), to be applied against the Guaranteed
Obligations of the Borrower, whether matured or unmatured, in such order as the
Administrative Agent may determine.

     10.  Amendment and Waiver; Cumulative Remedies; Severability.  No
          -------------------------------------------------------
amendment, modification, termination or waiver of any provision of this
Guaranty, or consent to any departure by any Guarantor herefrom, shall be
effective without the written concurrence of the Majority Banks under the Credit
Agreement or as otherwise provided in the Credit Agreement including, without
limitation, Section 11.01(a) thereof.  No failure by the Guaranteed Parties to
exercise, and no delay in exercising, any right, remedy or power hereunder shall
operate as a waiver thereof; nor shall any single or partial exercise of any
right, remedy or power hereunder preclude any other or further exercise thereof
or the exercise of any other right.  No waiver of any breach or default under
this Guaranty shall be deemed a waiver of any other breach or default hereunder.
The remedies herein provided are cumulative and not exclusive of any remedies
provided by law or in equity.  The unenforceability or invalidity of any
provision of this Guaranty shall not affect the enforceability or validity of
any other provision herein.

     11.  Notices.  All notices, requests and other communications provided for
          -------
hereunder shall be in writing (including, unless the context expressly otherwise
provides, facsimile transmission) and mailed, transmitted by facsimile or
delivered, (a) if to any Guarantors, to the address or facsimile number
specified for notices on the applicable signature page hereof; (b) if to any
Guaranteed Party, to the notice address specified for such party on Schedule
1.01(A) to the Credit Agreement; or (c) to such other address as shall be
designated by any party in a written notice to the other parties and the
Administrative Agent.

     12.  Stay of Acceleration.  In the event that acceleration of the time for
          --------------------
payment of any of the Guaranteed Obligations is stayed, upon the insolvency,
bankruptcy or reorganization of the Borrower or any other Person, or otherwise,
all such amounts shall nonetheless be payable by the Guarantor immediately upon
demand by the Guaranteed Parties.

     13.  Representations and Warranties.  In order to induce the Banks to make
          ------------------------------
Loans and the Issuing Bank to issue Letters of Credit pursuant to the Credit
Agreement, and in order to induce the Interest Rate Guaranteed Parties to
execute, deliver and perform the Interest Rate Protection Agreements, each
Guarantor represents, warrants and covenants that:

                                       5
<PAGE>

          (a) Such Guarantor (i) is a duly organized and validly existing
corporation, partnership or limited liability company, as the case may be, and
is in good standing under the laws of the jurisdiction of its organization, (ii)
has the power and authority and all governmental licenses, authorizations,
consents and approvals to own or hold under lease its property or assets,
conduct its business and execute, deliver, and perform its obligations under,
this Guaranty and the other Loan Documents to which it is a party, (iii) is duly
qualified to do business as a foreign entity, and licensed and in good standing,
under the laws of each jurisdiction where its ownership, lease or operation of
property or the nature or conduct of its business requires such qualification or
license, except where the failure to so qualify would not reasonably be expected
to have a Material Adverse Effect and (iv) is in compliance with all
Requirements of Law, except to the extent that the failure to do so could not
reasonably be expected to have a Material Adverse Effect.

          (b) This Guaranty and each other Loan Document to which such Guarantor
is a party constitutes the legal, valid and binding obligation of such
Guarantor, enforceable against such Guarantor in accordance with its terms,
except as enforceability may be limited by applicable bankruptcy, insolvency, or
other similar laws affecting creditors' rights generally and by equitable
principles of general application.

          (c) The execution, delivery and performance by such Guarantor of this
Guaranty and each other Loan Document to which such Guarantor is a party have
been duly authorized by all necessary corporate, limited liability company or
partnership action, as the case may be, and do not and will not (i) contravene
any terms of the Charter Documents of such Guarantor, (ii) conflict with or
result in any breach or contravention of, or the creation of any Lien (except
under the Security Documents) under, any document evidencing any material
Contractual Obligation to which such Guarantor is a party of any order,
injunction, writ or decree of any Governmental Authority to which such Guarantor
or its property is subject, or (iii) violate any Requirement of Law.

          (d) No approval, consent, exemption, authorization, or other action
by, or notice to, or filing with or approvals of any Governmental Authority is
necessary or required in connection with the execution, delivery or performance
by, or enforcement against (except as may be required by the Communications Act
of 1933, as amended, and the rules, regulations and policies of the FCC), such
Guarantor of this Guaranty and each other Loan Document to which such Guarantor
is a party.

          (e) There are no actions, suits or proceedings, claims or disputes
pending, or to the best knowledge of such Guarantor, threatened at law, in
equity, or in arbitration before any Governmental Authority, against such
Guarantor or any of its properties or assets which (i) purport to affect or
pertain to this Guaranty or any other Loan Document to which such Guarantor is a
party, or any of the transactions contemplated hereby, or (ii) would reasonably
be expected to have a Material Adverse Effect.  No injunction, writ, temporary
restraining order or any order of any nature has been issued by any court or
other Governmental Authority purporting to enjoin or restrain the execution,
delivery or performance of this Guaranty, or directing that any other
transaction provided for herein not be consummated as herein provided.

                                       6
<PAGE>

     14.  Credit Agreement Covenants.  Each Guarantor covenants and agrees that
          ---------------------------
on and after the date hereof and until the Aggregate Commitment and all Interest
Rate Protection Agreements have been terminated and no Loan or Letter of Credit
remains outstanding (other than Letters of Credit, together with all fees that
have accrued and will accrue thereon through the stated termination date of such
Letters of Credit, which have been supported in a manner satisfactory to the
Issuing Bank in its sole and absolute discretion) and all Guaranteed Obligations
have been paid in full (other than indemnities described in Section 11.05 of the
Credit Agreement and analogous provisions in the Security Documents which are
not then due and payable), such Guarantor shall take, or will refrain from
taking, as the case may be, all actions that are necessary to be taken or not
taken so that no violation of any provision, covenant or agreement contained in
Article VII or VIII of the Credit Agreement, and so that no Default or Event of
Default is caused by the actions of such Guarantor or any of its Subsidiaries.

     15.  Successors and Assigns.  This Guaranty shall be binding upon each
          ----------------------
Guarantor and its successors and assigns and shall inure to the benefit of the
respective successors and assigns of the Guaranteed Parties and, in the event of
any transfer or assignment of rights by any Guaranteed Party, the rights and
privileges herein conferred upon that Guaranteed Party shall automatically
extend to and be vested in such transferee or assignee, all subject to the terms
and conditions hereof, provided, however, that no Guarantor may assign any of
its rights or obligations hereunder without the consent of the Banks and any
such assignment without such consent shall be void.

     16.  Governing Law.  THIS GUARANTY SHALL BE DEEMED TO BE MADE UNDER, SHALL
          -------------
BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS
OF THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW.

     17.  Jurisdiction and Service. All judicial proceedings brought against any
          ------------------------
Guarantor with respect to this Guaranty may be brought in any state or federal
court of competent jurisdiction in the State of New York and by execution and
delivery of this Guaranty each Guarantor accepts for itself and in connection
with its properties, generally and unconditionally, the nonexclusive
jurisdiction of the aforesaid courts, and irrevocably agrees to be bound by any
judgment rendered thereby in connection with this Guaranty.  Each Guarantor
irrevocably and unconditionally waives, to the fullest extent it may legally and
effectively do so, any objection which it may now or hereafter have to the
laying of venue of any suit, action or proceeding arising out of or relating to
this Guaranty in any state or federal court in the State of New York.  Each
Guarantor irrevocably waives, to the fullest extent permitted by law, the
defense of an inconvenient forum to the maintenance of such action or proceeding
in any such court and irrevocably consents to service of process in the manner
provided for notices in Section 11.  Nothing in this Guaranty will affect the
right of any Guaranteed Party to serve process in any other manner permitted by
law.  If any agent appointed by any Guarantor refuses to accept service, each
Guarantor agrees that service upon it by mail shall constitute sufficient
notice.  Nothing herein shall affect the right of any Guaranteed Party to bring
proceedings against any Guarantor in the courts of any other jurisdiction.

     18.  Waiver of Jury Trial.  EACH GUARANTOR HEREBY WAIVES, TO THE FULLEST
          --------------------
EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO

                                       7
<PAGE>

A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT
OF, UNDER OR IN CONNECTION WITH THIS GUARANTY, THE CREDIT AGREEMENT OR ANY OTHER
LOAN DOCUMENT. Each Guarantor (a) certifies that no representative, agent or
attorney of any other party to the Loan Documents has represented, expressly or
otherwise, that such other party would not, in the event of litigation, seek to
enforce the foregoing waiver and (b) acknowledges that the Banks and the other
parties to the Loan Documents have been induced to enter into the Loan Documents
by, among other things, the foregoing waiver and certification.

     19.  Release. This Guaranty is a continuing and irrevocable guaranty of all
          -------
Guaranteed Obligations now or hereafter existing and may be released only in
accordance with Section 11.01 of the Credit Agreement.

     20.  Counterparts.  This Guaranty may be executed in any number of
          ------------
counterparts and by the different parties hereto on separate counterparts, each
of which when so executed and delivered shall be an original, but all of which
shall together constitute one and the same instrument.  A set of counterparts
originals executed by all the parties hereto shall be delivered to the
Administrative Agent, and a copy thereof shall be furnished to the Borrower or
any Guarantor upon request therefor.

     21.  Security Documents.  The obligations of each Guarantor are secured by
          ------------------
certain of the Security Documents.  Each Guarantor shall comply with all terms
and conditions of the Security Documents to which such Guarantor is a party, as
the same may be amended, restated, supplemented or otherwise modified from time
to time.

     22.  Additional Guarantors.  It is understood and agreed that any Person
          ---------------------
may become a party hereto by executing a Guaranty Supplement in the form of
Annex A attached hereto and delivering the same to the Administrative Agent.

expenses (including attorneys' fees) of collection, whether incurred by any
Grantor or the Collateral Agent, shall be borne by such Grantor.  The Collateral
Agent shall deliver a copy of each notice referred to in the preceding clause
(b) to the relevant Grantor; provided, that the failure by the Collateral Agent

to so notify such Grantor shall not affect the effectiveness of such notice or
the other rights of the Collateral Agent created by this Section 4.3.

legal proceeding relating thereto, or sell any Receivable or Contract, or
interest therein, without the prior written consent of the Collateral Agent,
except (a) as permitted by Section 4.5 hereof and (b) so long as no Event of
                           -----------
Default is then in existence in respect of which the Collateral Agent has given
notice that this exception is no longer applicable, such Grantor may modify,
make adjustments with respect to, extend or renew any Contracts in the ordinary

accepted lawful collection procedures) any and all amounts owing under or on
account of such Receivable or Contract, and apply forthwith upon receipt thereof
all such amounts as are so collected to the outstanding balance of such
Receivable or under such Contract, except that, unless an Event of Default has
occurred and is continuing, such Grantor may allow in the ordinary course of
business as adjustments to amounts owing under its Accounts and Contracts (a) an
extension or renewal of the time or times of payment, or settlement for less
than the total unpaid balance, which such Grantor finds appropriate in
accordance with its reasonable business judgment and (b) a refund or credit due
as a result of returned or damaged merchandise or improperly performed services

Grantor or the Collateral Agent, shall be borne by such Grantor.

     4.6. Instruments.  If any Grantor owns or acquires any Instrument
          -----------
constituting Security Agreement Collateral, such Grantor will within ten
Business Days notify the Collateral Agent thereof, and upon request by the
Collateral Agent will promptly deliver such Instrument to the Collateral Agent
appropriately endorsed to the order of the Collateral Agent as further security
hereunder.

     4.7. Further Actions.  Each Grantor will, at its own expense, make,

rights covered by the security interest hereby granted, as the Collateral Agent
may reasonably require to give effect to the purposes of this Agreement.

judgment, that the maintenance of such Mark is no longer necessary or desirable
in the conduct of its business. Each Grantor agrees to notify the Collateral
Agent three months prior to the dates on which the affidavits of use or the
application for renewal registration are due with respect to any registered Mark
that the affidavits of use are being processed or abandoned as the case may be.

     5.6. Future Registered Marks.  If any Mark registration issues hereafter to

such Grantor in and to each of the Marks and the goodwill of the business
associated therewith, together with all trademark rights and rights of
protection to the same, vested, in which event such rights, title and interest
shall immediately vest, in the Collateral Agent for the benefit of the Secured
Creditors pursuant to the grant of security interest in trademarks in the form

refrain, from using the Marks in any manner whatsoever, directly or indirectly,
and, if requested by the Collateral Agent, change such Grantor's corporate name
to eliminate therefrom any use of any Mark and execute such other and further
documents that the Collateral Agent may request to further confirm this and to
transfer ownership of the Marks and registrations and any pending trademark
application in the United States Patent and Trademark Office or any equivalent
government agency or office in any foreign jurisdiction to the Collateral Agent.

          ------------------------
Agreement and other than the license agreements listed on Schedule E hereto and
                                                          ----------

security interest in copyrights in the form of Annex B hereto, in each case,
                                               -------
executed by such Grantor and filed promptly after the date hereof, pursuant to
which all of such Grantor's right, title and interest to such Patents and
Copyrights are assigned to the Collateral Agent for the benefit of the Secured
Creditors; (b) take and practice or sell the Patents and Copyrights; and (c)
direct such Grantor to refrain, in which event such Grantor shall refrain, from

                                  ARTICLE VII.

            PROVISIONS CONCERNING ALL SECURITY AGREEMENT COLLATERAL

     7.1. Protection of Collateral Agent's Security.  No Grantor will do
          -----------------------------------------
anything to impair the rights of the Collateral Agent in the Security Agreement
Collateral.  Each Grantor will at all times keep its Inventory and Equipment
insured in favor of the Collateral Agent, at such Grantor's own expense to the
extent and in the manner provided in the Credit Agreement; all policies or
certificates with respect to such insurance shall be endorsed to the Collateral
Agent's satisfaction for the benefit of the Collateral Agent (including, without
limitation, by naming the Collateral Agent as loss payee) and deposited with the
Collateral Agent.  If any Grantor shall fail to insure its Inventory to the
extent required by the Credit Agreement, or if any Grantor shall fail to so
endorse and deposit all policies or certificates with respect thereto, the
Collateral Agent shall have the right (but shall be under no obligation) to
procure such insurance and such Grantor agrees to reimburse the Collateral Agent
for all costs and expenses of procuring such insurance.  The Collateral Agent
may apply any proceeds in accordance with Section 8.4 hereof or in accordance
                                          -----------
with the Credit Agreement.  Each Grantor assumes all liability and
responsibility in connection with the Security Agreement Collateral acquired by
it and the liability of such Grantor to pay its Obligations shall in no way be
affected or diminished by reason of the fact that such Security Agreement
Collateral may be lost, destroyed, stolen, damaged or for any reason whatsoever
unavailable to such Grantor.

     7.2. Warehouse Receipts Non-Negotiable.  Each Grantor agrees that if any
          ---------------------------------
warehouse receipt or receipt in the nature of a warehouse receipt is issued with
respect to any of its Inventory, such warehouse receipt or receipt in the nature
thereof shall not be "negotiable" (as such term is used in Section 7-104 of the
                      ----------
Uniform Commercial Code as in effect in any relevant jurisdiction or under other
relevant law).

     7.3. Further Actions.  Each Grantor will, at its own expense, make,
          ---------------
execute, endorse, acknowledge, file and/or deliver to the Collateral Agent from
time to time such lists, descriptions and designations of its Security Agreement
Collateral, warehouse receipts, receipts in the nature of warehouse receipts,
bills of lading, documents of title, vouchers, invoices, schedules, confirmatory
assignments, conveyances, financing statements, transfer endorsements, powers of
attorney, certificates, reports and other assurances or instruments and take
such further steps relating to the Security Agreement Collateral and other
property or rights covered by the security

                                       17
<PAGE>

interest hereby granted, which the Collateral Agent deems reasonably appropriate
to perfect, preserve or protect its security interest in the Security Agreement
Collateral.

     7.4. Financing Statements.  Each Grantor agrees to execute and deliver to
          --------------------
the Collateral Agent such financing statements, in form reasonably acceptable to
the Collateral Agent, as the Collateral Agent may from time to time reasonably
request or as are necessary or desirable in the opinion of the Collateral Agent
to establish and maintain a valid, enforceable, first-priority, perfected
security interest (subject to Permitted Liens) in the Security Agreement
Collateral as provided herein and the other rights and security contemplated
hereby, all in accordance with the Uniform Commercial Code as enacted in any and
all relevant jurisdictions or any other relevant law.  Each Grantor will pay any
applicable filing fees and related expenses.  Each Grantor authorizes the
Collateral Agent to file any such financing statements without the signature of
such Grantor.

                                 ARTICLE VIII.

                  REMEDIES UPON OCCURRENCE OF EVENT OF DEFAULT

     8.1. Remedies, Obtaining the Security Agreement Collateral Upon Default.
          ------------------------------------------------------------------
Each Grantor agrees that, if any Event of Default shall have occurred and be
continuing, then and in every such case, subject to any mandatory requirements
of applicable law then in effect, the Collateral Agent, in addition to any
rights now or hereafter existing under applicable law, shall have all rights as
a secured creditor under the Uniform Commercial Code in all relevant
jurisdictions and may:

          (a)  personally, or by agents or attorneys, immediately take
     possession of the Security Agreement Collateral or any part thereof, from
     such Grantor or any other Person who then has possession of any part
     thereof, with or without notice or process of law, and for that purpose may
     enter upon such Grantor's premises where any of the Security Agreement
     Collateral is located and remove the same and use in connection with such
     removal any and all servic es, supplies, aids and other facilities of such
     Grantor;

          (b)  instruct the obligor or obligors on any agreement, instrument or
     other obligation (including, without limitation, the Accounts) constituting
     the Security Agreement Collateral to make any payment required by the terms
     of such agreement or instrument directly to the Collateral Agent;

          (c)  withdraw all monies, securities and other instruments in the Cash
     Collateral Account for application to the Obligations in accordance with
     Section 8.4;
     -----------

          (d)  sell, assign or otherwise liquidate, or direct such Grantor to
     sell, assign or otherwise liquidate, any or all of the Security Agreement
     Collateral or any part thereof in accordance with Section 8.2 and take
                                                       -----------
     possession of the proceeds of any such sale or liquidation;

          (e)  take possession of the Security Agreement Collateral, or any part
     thereof, by directing such Grantor in writing to deliver the same to the
     Collateral Agent at any

                                       18
<PAGE>

     place or places designated by the Collateral Agent, in which event such
     Grantor shall at its own expense:

                (i)   forthwith cause the same to be moved to the place or
          places so designated by the Collateral Agent and there delivered to
          the Collateral Agent,

                (ii)  store and keep any Security Agreement Collateral so
          delivered to the Collateral Agent at such place or places pending
          further action by the Collateral Agent as provided in Section 8.2, and
                                                                -----------

                (iii) while the Security Agreement Collateral shall be so stored
          and kept, provide such guards and maintenance services as shall be
          necessary to protect the same and to preserve and maintain it in good
          condition; and

          (f)   license or sublicense, whether on an exclusive or nonexclusive
     basis, any Marks, Patents or Copyrights included in the Security Agreement
     Collateral for such term and on such conditions and in such manner as the
     Collateral Agent shall in its sole judgment determine (taking into account
     such provisions as may be necessary to protect and preserve such Marks,
     Patents or Copyrights);

it being understood that such Grantor's obligation to so deliver the Security
Agreement Collateral is of the essence of this Agreement and that, accordingly,
upon application to a court of equity having jurisdiction, the Collateral Agent
shall be entitled to a decree requiring specific performance by such Grantor of
said obligation.

     8.2. Remedies, Disposition of the Security Agreement Collateral.  Upon the
          ----------------------------------------------------------
occurrence and during the continuance of an Event of Default, any Security
Agreement Collateral repossessed by the Collateral Agent under or pursuant to
Section 8.1 and any other Security Agreement Collateral whether or not so
-----------
repossessed by the Collateral Agent may be sold, assigned, leased, licensed or
otherwise disposed of under one or more contracts or as an entirety, and without
the necessity of gathering at the place of sale the property to be sold, and in
general in such manner, at such time or times, at such place or places and on
such terms as the Collateral Agent may, in compliance with any mandatory
requirements of applicable law, determine to be commercially reasonable.  Any of
the Security Agreement Collateral may be sold, leased, licensed or otherwise
disposed of, in the condition in which the same existed when taken by the
Collateral Agent or after any overhaul or repair (at the expense of the relevant
Grantor) which the Collateral Agent shall determine to be commercially
reasonable.  Any such disposition which shall be a private sale or other private
proceedings permitted by such requirements shall be made upon not less than 10
days written notice to the relevant Grantor specifying the time at which such
disposition is to be made and the intended sale price or other consideration
therefor and shall be subject, for the 10 days after the receipt of such notice,
to the right of the relevant Grantor or any nominee of such Grantor to acquire
the Security Agreement Collateral involved at a price or for such other
consideration at least equal to the intended sale price or other consideration
so specified.  Any such disposition which shall be a public sale permitted by
such requirements shall be made upon not less than 10 days written notice to the
relevant Grantor specifying the time and place of such sale.  To the extent
permitted by any such requirement of law, the Collateral Agent, on behalf of the
Secured Creditors, may bid for and

                                       19
<PAGE>

become the purchaser of the Security Agreement Collateral or any item thereof
offered for sale in accordance with this Section 8.2 without accountability to
                                         -----------
the relevant Grantor. If, under mandatory requirements of applicable law, the
Collateral Agent shall be required to make disposition of the Security Agreement
Collateral within a period of time which does not permit the giving of notice to
the relevant Grantor as hereinabove specified, the Collateral Agent need give
such Grantor only such notice of disposition as shall be reasonably practicable
in view of such mandatory requirements of applicable law. Each Grantor agrees to
do or cause to be done all such other acts and things as may be reasonably
necessary to make such sale or sales of all or any portion of the Security
Agreement Collateral valid and binding and in compliance with all applicable
laws, regulations, orders, writs, injunctions, decrees or awards of any and all
courts, arbitrators or governmental instrumentalities, domestic or foreign,
having jurisdiction over any such sale or sales, all at such Grantor's expense.

     8.3. WAIVER OF CLAIMS.  EXCEPT AS OTHERWISE PROVIDED IN THIS AGREEMENT,
          ----------------
EACH GRANTOR HEREBY WAIVES, TO THE EXTENT PERMITTED BY APPLICABLE LAW, NOTICE
AND JUDICIAL HEARING IN CONNECTION WITH THE COLLATERAL AGENT'S TAKING POSSESSION
OR THE COLLATERAL AGENT'S DISPOSITION OF ANY OF THE SECURITY AGREEMENT
COLLATERAL, INCLUDING, WITHOUT LIMITATION, ANY AND ALL PRIOR NOTICE AND HEARING
FOR ANY PREJUDGMENT REMEDY OR REMEDIES AND ANY SUCH RIGHT WHICH SUCH GRANTOR
WOULD OTHERWISE HAVE UNDER THE CONSTITUTION OR ANY STATUTE OF THE UNITED STATES
OR OF ANY STATE, AND EACH GRANTOR HEREBY FURTHER WAIVES, TO THE EXTENT PERMITTED
BY LAW:

          (a)  all damages occasioned by such taking of possession except any
     damages which are the direct result of the Collateral Agent's gross
     negligence or willful misconduct;

          (b)  all other requirements as to the time, place and terms of sale or
     other requirements with respect to the enforcement of the Collateral
     Agent's rights hereunder; and

          (c)  all rights of redemption, appraisement, valuation, stay,
     extension or moratorium now or hereafter in force under any applicable law
     in order to prevent or delay the enforcement of this Agreement or the
     absolute sale of the Security Agreement Collateral or any portion thereof,
     and each Grantor, for itself and all who may claim under it, insofar as it
     or they now or hereafter lawfully may, hereby waives the benefit of all
     such laws.

Any sale of, or the grant of options to purchase, or any other realization upon,
any Security Agreement Collateral shall operate to divest all right, title,
interest, claim and demand, either at law or in equity, of the relevant Grantor
therein and thereto, and shall be a perpetual bar both at law and in equity
against such Grantor and against any and all Persons claiming or attempting to
claim the Security Agreement Collateral so sold, optioned or realized upon, or
any part thereof, from, through and under such Grantor.

     8.4. Application of Proceeds.
          -----------------------

          (a)  All monies collected by the Collateral Agent (or, to the extent
     any Pledge Agreement or any Mortgage requires proceeds of Security
     Agreement Collateral under such Security Documents to be applied in
     accordance with the provisions of this Agreement, the Collateral Agent or
     Mortgagee under such other Security Document) upon any sale or other
     disposition of the Security Agreement Collateral, together with all other
     monies received by the Collateral Agent hereunder, shall be applied as
     follows:

               (i)    first, to the payment of all Obligations owing to the
          Collateral Agent of the type described in clauses (b) and (c) of the
          definition of "Obligations" contained in Section 2.2 hereof;
                         -----------               -----------

               (ii)   second, to the extent proceeds remain after the
          application pursuant to the preceding clause (i), an amount equal to
          the outstanding Primary Obligations shall be paid to the Secured
          Creditors as provided in Section 8.4(e), with each Secured Creditor
                                   --------------
          receiving an amount equal to such outstanding Primary Obligations (as
          defined in paragraph (b) below) or, if the proceeds are insufficient
          to pay in full all such Primary Obligations, its Pro Rata Share (as
          defined in paragraph (b) below) of the amount remaining to be
          distributed;

               (iii)  third, to the extent proceeds remain after the
          application pursuant to the preceding clauses (i) and (ii), an amount
          equal to the outstanding Secondary Obligations shall be paid to the
          Secured Creditors as provided in Section 8.4(e), with each Secured
                                           --------------
          Creditor receiving an amount equal to its outstanding Secondary
          Obligations or, if the proceeds are insufficient to pay in full all
          such Secondary Obligations, its Pro Rata Share of the amount remaining
          to be distributed; and

               (iv)   fourth, to the extent proceeds remain after the
          application pursuant to the preceding clauses (i) through (iii),
          inclusive, and following the termination of this Agreement pursuant to
          Section 10.10 hereof, to the relevant Grantor or to whomever may be
          -------------
          lawfully entitled to receive such surplus.

          (b) For purposes of this Agreement, (i) "Pro Rata Share" shall mean,
                                                   --------------
     when calculating a Secured Creditor's portion of any distribution or
     amount, that amount (expressed as a percentage) equal to a fraction, the
     numerator of which is the then unpaid amount of such Secured Creditor's
     Primary Obligations or Secondary Obligations, as the case may be, and the
     denominator of which is the then outstanding amount of all Primary
     Obligations or Secondary Obligations, as the case may be, (ii) "Primary
                                                                     -------
     Obligations" shall mean (w) in the case of the Loan Document Obligations,
     -----------
     all principal of, and interest on, all Loans, all Letter of Credit
     Obligations (together with all interest accrued thereon) and all fees
     payable pursuant to the Loan Documents, (x) in the case of the Interest
     Rate Protection Obligations, all amounts due under the Interest Rate
     Protection Agreements (other than indemnities, fees (including, without
     limitation, attorneys' fees) and similar obligations and liabilities), (y)
     all obligations and liabilities of each Grantor to the Management Loan
     Creditor, now existing or hereinafter incurred under, arising out of

                                       21
<PAGE>

     or in connection with the Management Loan Guaranty and (z) all obligations
     and liabilities of each Grantor to the Bastet/Mission Creditors, now
     existing and hereafter incurred under, arising out of or in connection with
     the Bastet/Mission Guaranty and (iii) "Secondary Obligations" shall mean
                                            ---------------------
     all Obligations other than Primary Obligations.

          (c)  When payments to the Secured Creditors are based upon their
     respective Pro Rata Shares, the amounts received by such Secured Creditors
     hereunder shall be applied (for purposes of making determinations under
     this Section 8.4 only) (i) first, to their Primary Obligations and (ii)
          -----------
     second, to their Secondary Obligations.  If any payment to any Secured
     Creditor of its Pro Rata Share of any distribution would result in
     overpayment to such Secured Creditor, such excess amount shall instead be
     distributed in respect of the unpaid Primary Obligations or Secondary
     Obligations, as the case may be, of the other Secured Creditors, with each
     Secured Creditor whose Primary Obligations or Secondary Obligations, as the
     case may be, have not been paid in full to receive an amount equal to such
     excess amount multiplied by a fraction, the numerator of which is the
     unpaid Primary Obligations or Secondary Obligations, as the case may be, of
     such Secured Creditor and the denominator of which is the unpaid Primary
     Obligations or Secondary Obligations, as the case may be, of all Secured
     Creditors entitled to such distribution.

          (d)  Each of the Secured Creditors agrees and acknowledges that if the
     Bank Creditors are to receive a distribution on account of undrawn amounts
     with respect to Letters of Credit issued (or deemed issued) under the
     Credit Agreement (which shall only occur after all outstanding Loans and
     Letter of Credit Obligations with respect to such Letters of Credit have
     been paid in full), such amounts shall be paid to the Administrative Agent
     under the Credit Agreement and held by it, for the equal and ratable
     benefit of the Bank Creditors, as cash security for the repayment of
     Obligations owing to the Bank Creditors as such.  If any amounts are held
     as cash security pursuant to the immediately preceding sentence, then upon
     the termination of all outstanding Letters of Credit, and after the
     application of all such cash security to the repayment of all Obligations
     owing to the Bank Creditors after giving effect to the termination of all
     such Letters of Credit, if there remains any excess cash, such excess cash
     shall be returned by the Administrative Agent to the Collateral Agent for
     distribution in accordance with Section 8.4(a) hereof.
                                     --------------

          (e)  Except as set forth in Section 8.4(d) hereof, all payments
                                      --------------
     required to be made hereunder shall be made (i) if to the Bank Creditors,
     to the Administrative Agent under the Credit Agreement for the account of
     the Bank Creditors, and (ii) if to the other Secured Creditors, to the
     trustee, paying agent or other similar representative (each a
     "Representative") for the other Secured Creditors or, in the absence of
      --------------
     such a Representative, directly to the other Secured Creditors.

          (f)  For purposes of applying payments received in accordance with
     this Section 8.4, (i) the Collateral Agent shall determine the unpaid
          -----------
     Primary Obligations and the other Loan Document Obligations owed to the
     Bank Creditors and (ii) the Collateral Agent may rely on (x) any Interest
     Rate Protection Creditor to determine the unpaid Primary Obligations and
     other Interest Rate Protection Obligations owed to such Interest Rate
     Protection Creditor, (y) any Bastet/Mission Creditor to determine the
     unpaid

                                       22
<PAGE>

     Primary Obligations and other Bastet/Mission Guaranty Obligations owed to
     such Bastet/Mission Creditor and (z) the Management Loan Creditor to
     determine the unpaid Primary Obligations and other Management Loan Guaranty
     Obligations owed to the Management Loan Creditor.

           (g)  It is understood and agreed that the Grantors shall remain
     jointly and severally liable to the extent of any deficiency between the
     amount of the proceeds of the Security Agreement Collateral hereunder and
     the aggregate amount of the sums referred to in clauses (i) through (iii),
     inclusive, of Section 8.4(a).
                   --------------

     8.5.  Remedies Cumulative.  Each and every right, power and remedy hereby
           -------------------
specifically given to the Collateral Agent shall be in addition to every other
right, power and remedy specifically given under this Agreement, the Interest
Rate Protection Agreements, the other Loan Documents, the Management Loan
Guaranty or the Bastet/Mission Guaranty now or hereafter existing at law or in
equity, or by statute, and each and every right, power and remedy whether
specifically herein given or otherwise existing may be exercised from time to
time or simultaneously and as often and in such order as may be deemed expedient
by the Collateral Agent. All such rights, powers and remedies shall be
cumulative, and the exercise or the beginning of exercise of one shall not be
deemed a waiver of the right to exercise of any other or others. No delay or
omission of the Collateral Agent in the exercise of any such right, power or
remedy and no renewal or extension of any of the Obligations and no course of
dealing between any Grantor and the Collateral Agent or any holder of any of the
Obligations shall impair any such right, power or remedy or shall be construed
to be a waiver of any Default or Event of Default or an acquiescence therein. In
the event that the Collateral Agent shall bring any suit to enforce any of its
rights hereunder and shall be entitled to judgment, then in such suit the
Collateral Agent may recover reasonable expenses, including attorneys' fees, and
the amounts thereof shall be included in such judgment.

     8.6.  Discontinuance of Proceedings.  In case the Collateral Agent shall
           -----------------------------
have instituted any proceeding to enforce any right, power or remedy under this
Agreement by foreclosure, sale, entry or otherwise, and such proceeding shall
have been discontinued or abandoned for any reason or shall have been determined
adversely to the Collateral Agent, then and in every such case the relevant
Grantor, the Collateral Agent and the holders of any of the Obligations shall be
restored to their former positions and rights hereunder with respect to the
Security Agreement Collateral subject to the security interest created under
this Agreement, and all rights, remedies and powers of the Collateral Agent
shall continue as if no such proceeding had been instituted.

     --------------
     the gross negligence or willful misconduct of such Indemnitee. Each Grantor
     agrees that upon written notice by any Indemnitee of the assertion of such
     a liability, obligation, loss, damage, penalty, claim, demand, action, suit
     or judgment, such Grantor shall assume full responsibility for the defense

     and expenses of whatever kind or nature incurred in connection with the
     creation, preservation or protection of the Collateral Agent's Liens on,

     without limitation, all fees and taxes in connection with the recording or
     filing of instruments and documents in public offices, payment or discharge
     of any taxes or Liens upon or in respect of the Security Agreement
     Collateral, premiums for insurance with respect to the Security Agreement
     Collateral and all other reasonable fees, costs and expenses in connection
     with protecting, maintaining or preserving the Security Agreement
     Collateral and the Collateral Agent's interest therein, whether through
     judicial proceedings or otherwise, or in defending or prosecuting any
     actions, suits or proceedings arising out of or relating to the Security
     Agreement Collateral.

           (c)  Without limiting the application of Section 9.1(a) or (b), each
                                                   --------------    ---
     Grantor agrees to pay, indemnify and hold each Indemnitee harmless from and
     against any loss, costs, damages and expenses which such Indemnitee may

<PAGE>

           (d)  If and to the extent that the obligations of any Grantor under
     this Section 9.1 are unenforceable for any reason, such Grantor hereby
          -----------
     agrees to make the maximum contribution to the payment and satisfaction of
     such obligations which is permissible under applicable law.

     9.2.  Indemnity Obligations Secured by Security Agreement Collateral;

           (a)  No amendment or waiver of any provision of this Agreement, nor

           (b)  No delay on the part of the Collateral Agent in exercising any

of each Grantor under or with respect to any Security Agreement Collateral,
except to the extent directly resulting from the Collateral Agent's gross
negligence or willful misconduct.

           (a)  Notwithstanding anything contrary contained in this Agreement,
     or any of the documents executed pursuant hereto, the Collateral Agent will
     not take any action pursuant to this Agreement, or any such documents,
     which would constitute or result in any assignment of any FCC License or
     any transfer of control of the holder of any FCC License if such assignment
     of such license or such transfer of control would require under

                                       27
<PAGE>

     then-existing law (including the Communications Act and the written rules,
     regulations and policies promulgated by the FCC), the prior approval of the
     FCC, without first obtaining such approval. In connection with this Section
                                                                         -------
     10.9, the Collateral Agent shall be entitled to rely in good faith upon an
     ----
     opinion of outside FCC counsel of the Collateral Agent's choice with
     respect to such assignment or transfer, whether or not the advice rendered
     is ultimately determined to have been accurate. To the extent that such an
     opinion is requested, a copy of such opinion shall be delivered to each
     Grantor.

           (b)  If an Event of Default shall have occurred, each Grantor shall
     take any action which the Collateral Agent may request in the exercise of
     its rights and remedies under this Agreement in order to transfer or assign
     the Security Agreement Collateral to the Collateral Agent or to such one or
     more third parties as the Collateral Agent may designate, or to a
     combination of the foregoing.  To enforce the provisions of this Section
                                                                      -------
     10.9, the Collateral Agent is empowered to seek from the FCC and any other
     ----
     Governmental Authority, to the extent required, consent to or approval of
     any involuntary transfer of control of any entity whose Security Agreement
     Collateral is subject to this Agreement for the purpose of seeking a bona
     fide purchaser to whom control will ultimately be transferred.  Each
     Grantor agrees to cooperate with any such purchaser and with the Collateral
     Agent in the preparation, execution and filing of any forms and providing
     any information that may be necessary or helpful in obtaining the FCC's
     consent to the assignment to such purchaser of the Security Agreement
     Collateral.  Each Grantor hereby agrees to consent to any such involuntary
     transfer of control upon the request of the Collateral Agent after and
     during the continuation of an Event of Default and, without limiting any
     rights of the Collateral Agent under this Agreement, to authorize the
     Collateral Agent to nominate a trustee or receiver to assume control of the
     Security Agreement Collateral, subject only to required judicial, FCC or
     other consent required by any Governmental Authority, in order to
     effectuate the transactions contemplated in this Section 10.9.  Such
                                                      ------------
     trustee or receiver shall have all the rights and powers as provided to it
     by law or court order, or to the Collateral Agent under this Agreement.
     Each Grantor shall cooperate fully in obtaining the consent of the FCC and
     the approval or consent of each other Governmental Authority required to
     effectuate the foregoing.

           (c)  Each Grantor shall use its best efforts to assist in obtaining
     the consent or approval of the FCC and any other Governmental Authority, if
     required, for any action or transactions contemplated by this Agreement,
     including, without limitation, the preparation, execution and filing with
     the FCC of the transferor's or Grantor's portion of any application or
     applications for consent to the transfer of control or assignment necessary
     or appropriate under the FCC's rules and regulations for approval of the
     transfer or assignment of any portion of the Security Agreement Collateral.
     Anything herein to the contrary notwithstanding, no Grantor shall be
     obligated to sign any such document which such Grantor has reasonable cause
     to believe contains any inaccuracy or to make any statements concerning the
     qualifications of any transferee or assignee.

           (d)  Each Grantor hereby acknowledges and agrees that the Security
     Agreement Collateral is a unique asset and that a violation of such
     Grantor's covenant to cooperate with respect to any regulatory consents
     would result in irreparable harm to the

                                       28
<PAGE>

     Collateral Agent for which monetary damages are not readily ascertainable.
     Each Grantor further agrees that, because of the unique nature of its
     undertakings in this Section 10.9, the same may be specifically enforced,
                          ------------
     and it hereby waives, and agrees to waive, any claim or defense that the
     Collateral Agent would have an adequate remedy at law for the breach of
     such undertakings.

           (e)  Without limiting the obligations of any Grantor hereunder in
     any respect, each Grantor further agrees that if such Grantor, upon or
     after the occurrence of an Event of Default, should fail or refuse for any
     reason whatsoever, without limitation, including any refusal pursuant to
     Section 10.9(c) to execute any application necessary or appropriate to
     ---------------
     obtain any governmental consent necessary or appropriate for the exercise
     of any right of the Collateral Agent hereunder, such Grantor agrees that
     such application may be executed on such Grantor's behalf by the clerk of
     court or other representative of any court or other forum of competent
     jurisdiction without notice to such Grantor pursuant to an order of such
     court or forum.

     10.10.  Termination; Release.
             ---------------------

             (a)  After the Lien Termination Date (as defined below), this
     Agreement shall terminate, and the Collateral Agent, at the request and
     expense of the relevant Grantor, will execute and deliver to such Grantor
     such instrument or instruments (including Uniform Commercial Code
     termination statements on Form UCC-3) acknowledging the satisfaction and
     termination of this Agreement as reasonably requested by such Grantor, and
     will duly assign, transfer and deliver to such Grantor (without recourse
     and without any representation or warranty) such of the Security Agreement
     Collateral as may be in the possession of the Collateral Agent and has not
     theretofore been sold or otherwise applied or released pursuant to this
     Agreement. As used in this Agreement, "Lien Termination Date" shall mean
                                            ---------------------
     the date upon which (i) all Obligations under the Credit Agreement and the
     other Loan Documents (other than indemnities for which no request for
     payment has been made) have been paid in full and all Letters of Credit and
     commitments thereunder have been terminated and the obligations of the
     Grantors under the Management Loan Guaranty and the Bastet/Mission Guaranty
     have terminated in accordance or (ii) the Collateral Agent and, to the
     extent required by Section 11.01(a)(vii) of the Credit Agreement, each of
     the Banks shall have released all of the Security Agreement Collateral.

             (b) In the event that any part of the Security Agreement Collateral
     is sold in connection with a sale permitted by Section 8.03 of the Credit
     Agreement or otherwise released at the direction of the Majority Banks (or
     all Banks if required by Section 11.01(a)(vii) of the Credit Agreement) and
     the proceeds of such sale or sales or from such release are applied in
     accordance with the provisions of Section 2.07 of the Credit Agreement or
     such direction, to the extent required to be so applied, such Security
     Agreement Collateral will be sold free and clear of the Liens created by
     this Agreement and the Collateral Agent, at the request and expense of the
     respective Grantor, will duly assign, transfer and deliver to such Grantor
     (without recourse and without any representation or warranty) such of the
     Security Agreement Collateral as is then being (or

                                       29
<PAGE>

     has been) so sold or released and has not theretofore been released
     pursuant to this Agreement.

            (c)  At any time that any Grantor desires that the Collateral Agent
     take any action to acknowledge or give effect to any release of Security
     Agreement Collateral pursuant to the foregoing Section 10.10(a) or (b) it
                                                    ----------------    ---
     shall deliver to the Collateral Agent a certificate signed by an authorized
     officer stating that the release of such Security Agreement Collateral is
     permitted pursuant to Section 10.10(a) or (b).  Upon any release of
                           ----------------    ---
     Security Agreement Collateral pursuant to Section 10.10(a) or (b), none of
                                               ----------------    ---
     the Secured Creditors shall have any continuing right or interest in such
     Security Agreement Collateral, or, if the release is pursuant to Section
                                                                      -------
     10.10(a), the proceeds thereof.
     --------

            (d)  The Collateral Agent shall have no liability whatsoever to any
     Secured Creditor as a result of any release of any Security Agreement
     Collateral by it in accordance with this Section 10.10.
                                              -------------

     10.11. Counterparts.  This Agreement may be executed in any number of
            ------------
counterparts and by the different parties hereto on separate counterparts, each
of which when so executed and delivered shall be an original, but all of which
shall together constitute one and the same instrument.  A set of counterpart
originals executed by all the parties hereto shall be delivered to the
Collateral Agent, and a copy thereof shall be furnished to the Borrower or any
Grantor promptly upon request therefor.

     10.12. The Collateral Agent.  The Collateral Agent will hold in accordance
            --------------------
with this Agreement all items of the Security Agreement Collateral at any time
received under this Agreement.  It is expressly understood and agreed by the
parties hereto and each Secured Creditor that the obligations of the Collateral
Agent as holder of the Security Agreement Collateral and interests therein and
with respect to the disposition thereof, and otherwise under this Agreement, are
only those expressly set forth in this Agreement.  The Collateral Agent shall
act hereunder on the terms and conditions set forth in Article X of the Credit
                                                       ---------
Agreement.

     10.13. Decisions Relating to Exercise of Remedies.
            ------------------------------------------

            (a) Notwithstanding anything to the contrary contained in this
     Agreement, the Credit Agreement and the other Loan Documents, or any
     Interest Rate Protection Agreement, or the Management Loan Guaranty or the
     Bastet/Mission Guaranty, the Collateral Agent may, and at the request of
     the Majority Banks shall, exercise or refrain from exercising, all rights
     and remedies hereunder and provided by law, which remedies are cumulative
     and not exclusive.

            (b) By acceptance of the benefit of the security interests granted
     pursuant to this Agreement in the Security Agreement Collateral, the
     Interest Rate Protection Creditors, the Management Loan Creditor and the
     Bastet/Mission Creditors hereby acknowledge that they have no rights to
     direct the Collateral Agent to act or refrain from acting with respect to
     the Security Agreement Collateral, and hereby acknowledge that the
     Collateral Agent shall hold the Security Agreement Collateral (to the
     extent such Security Agreement Collateral is evidenced by certificates,
     notes or other instruments

                                       30
<PAGE>

     delivered to it) for itself and the pro rata benefit of the Secured
     Creditors, subject to the terms and conditions hereof, solely for the
     purpose of providing them with a pari passu security interest in the
                                      ---- -----
     Security Agreement Collateral (subject to the terms and conditions set
     forth herein). In any proceeding under the Bankruptcy Code or any other
     federal or state bankruptcy, insolvency, receivership or similar law and
     prior to any vote in any such proceeding, the Interest Rate Protection
     Creditors, the Management Loan Creditor and the Bastet/Mission Creditors
     shall abstain from any such vote which is taken on a committee of secured
     creditors or otherwise affects the disposition of the Security Agreement
     Collateral.

     10.14. Joinder.

            (a) Each Grantor shall cause each of its Subsidiaries that may from
     time to time be formed and that is not already a party hereto to become a
     "Grantor" hereunder by executing and delivering to the Collateral Agent a
     Joinder to Security Agreement substantially the form of Annex C hereto.
                                                             -------
     Any such Subsidiary shall thereafter be deemed a "Grantor" for all purposes
     under this Agreement.

            (b) Each Grantor further agrees to take such actions as the
     Collateral Agent reasonably deems necessary or desirable to effect the
     foregoing and to permit the Collateral Agent to exercise any of its rights
     and remedies hereunder, and agrees to provide an opinion of counsel
     reasonably satisfactory to the Collateral Agent with respect to the
     validity and perfection of any security interest granted hereunder, any
     such Subsidiary that is to become a party hereto and such other matters as
     may be reasonably requested by the Collateral Agent, in each case promptly
     upon request of the Collateral Agent
