collect or enforce any claim for payment assigned hereunder.  Notwithstanding
any of the foregoing, this Agreement shall not in any way be deemed to obligate
Secured Party, any other Agent, any Lender or any purchaser at a foreclosure
sale under this Agreement to assume any of any Grantor's obligations, duties,
expenses or liabilities under any LLC Agreement or Partnership Agreement
(including any Grantor's obligations as a general partner for the debts and
obligations of a Partnership) and to manage the business and affairs of any
Partnership or any of such Grantor's obligations for the debts and obligations
of an LLC, or under any and all other agreements now existing or hereafter
drafted or executed (collectively, the "Grantor Obligations") unless Secured
                                        -------------------
Party, any other Agent, any Lender or any such purchaser otherwise expressly
agrees in writing to assume any or all of said Grantor Obligations.  In the
event of foreclosure by Secured Party, each Grantor shall remain bound and
obligated to perform its Grantor Obligations arising during or otherwise related
to its ownership of the Collateral, and neither Secured Party, nor any other
Agent nor any Lender shall be deemed to have assumed any of such Grantor
Obligations except as provided in the preceding sentence.  Without limiting the
generality of the foregoing, neither the grant of the security interest in the
Collateral in favor of Secured Party as provided herein nor the exercise by
Secured Party of any of its rights hereunder nor any action in connection with a
foreclosure on the Collateral shall be deemed to constitute Secured Party, any
other Agent, or any Lender a partner of any Partnership or a member of any LLC;
provided, in the event Secured Party or any purchaser of Collateral at a
foreclosure sale elects to become a substituted general partner of any
Partnership or manager of any LLC in place of any Grantor, Secured Party or such
purchaser, as the case may, shall adopt in writing the applicable Partnership
Agreement or LLC Agreement, as the case may be, and agree to be bound by the
terms and provisions thereof.

Copyright, then in any such case, the provisions of this Agreement shall
automatically apply thereto.  Each Grantor shall promptly notify Secured Party
in writing of any of the foregoing rights acquired by Grantor after the date
hereof and of (i) any Trademark registrations issued or applications for
Trademark registration or applications for Patents made, and  (ii) any Copyright
registrations issued or applications for Copyright registration made, in any
such case, after the date hereof.  Promptly after the filing of an application

                                  EXHIBIT I-11
<PAGE>

Supplement, pursuant to which Grantor shall grant to Secured Party a security
interest to the extent of its interest in such Intellectual Property; provided,
if, in the reasonable judgment of Grantor, after due inquiry, granting such
interest would result in the grant of a Trademark registration or Copyright
registration in the name of Secured Party, in which event Grantor shall give
written notice to Secured Party as soon as reasonably practicable and the filing
shall instead be undertaken as soon as practicable following the grant of the
applicable Trademark registration or Copyright registration, as the case may be.
In addition to the foregoing, each Grantor hereby authorizes Secured Party to
modify this Agreement without obtaining Grantor's approval of or signature to
such modification by amending Schedule 1.1(b), as applicable, to include
reference to any right, title or interest in any existing Intellectual Property
or any Intellectual Property acquired or developed by Grantor after the
execution hereof or to delete any reference to any right, title or interest in

perfection thereof, upon the reasonable request of Secured Party, execute and
file with the registrar of motor vehicles or other appropriate authority in such
jurisdiction an application or other document requesting the notation or other
indication of the security interest created hereunder on such certificate of
title, and (b) upon the reasonable request of Secured Party, deliver to Secured
Party copies of all such applications or other documents filed during such
calendar quarter and copies of all such certificates of title issued during such
calendar quarter indicating the security interest created hereunder in the items
of Equipment covered thereby.

     4.6.  Additional Grantors.  From time to time subsequent to the date
hereof, additional Persons may become parties hereto as additional Grantors
(each, an "Additional Grantor"), by executing a Counterpart Agreement.  Upon
           ------------------
delivery of any such Counterpart Agreement to Secured Party, notice of which is
hereby waived by Grantors, each Additional Grantor shall be a Grantor and shall
be as fully a party hereto as if Additional Grantor were an original signatory
hereto.  Each Grantor expressly agrees that its obligations arising hereunder
shall not be affected or diminished by the addition or release of any other
Grantor hereunder, nor by any election of

                                  EXHIBIT I-12
<PAGE>

Secured Party not to cause any Subsidiary of Borrower to become an Additional

     SHALL BE EFFECTIVE, AUTOMATICALLY AND WITHOUT THE NECESSITY OF ANY ACTION
     (INCLUDING ANY TRANSFER OF ANY PLEDGED STOCK ON THE RECORD BOOKS OF THE
     ISSUER THEREOF) BY ANY OTHER PERSON (INCLUDING THE ISSUER OF THE PLEDGED
     STOCK OR ANY OFFICER OR AGENT THEREOF), UPON THE OCCURRENCE AND DURING THE
     CONTINUATION OF AN EVENT OF DEFAULT, AND WHICH PROXY SHALL ONLY TERMINATE
     UPON THE PAYMENT IN FULL OF THE SECURED OBLIGATIONS.

     5.3.  Intellectual Property Collateral.

              (a) Covenants.  Each Grantor shall (i) hereafter use best efforts
                  ---------
so as not to permit the inclusion in any contract to which it hereafter becomes
a party of any provision that could or might in any way materially impair or
prevent the creation of a security interest in, or the assignment of, Grantor's
rights and interests in any property included within the definitions of any
Intellectual Property Collateral acquired under such contracts; (ii) take all
steps reasonably necessary to protect the secrecy of all trade secrets relating
to the products and services sold or delivered under or in connection with the
Intellectual Property Collateral, including, without limitation, entering into
confidentiality agreements with employees and labeling and restricting access to
secret information and documents; (iii) use proper statutory notice in
connection with its use of any of the Intellectual Property Collateral; (iv) use
consistent standards of high quality (which may be consistent with Grantor's
past practices) in the manufacture, sale and delivery of products and services
sold or delivered under or in connection with the Intellectual Property
Collateral; and (v) furnish to Secured Party from time to time statements and
schedules further identifying and describing any Intellectual Property
Collateral and such other reports in connection with such Collateral as Secured
Party may reasonably request, all in reasonable detail.

              (b) Collections.  Except as otherwise provided in this Section
                  -----------
5.3, each Grantor shall continue to collect, at its own expense, all amounts due
or to become due to Grantor in respect of the Intellectual Property or any
portion thereof. In connection with such collections, each Grantor may take
(and, at Secured Party's reasonable direction, shall take) such action as
Grantor or Secured Party may deem reasonably necessary or advisable to enforce
collection of such amounts; provided, Secured Party shall have the right at any
time, upon the occurrence and during the continuation of an Event of Default and
upon written notice to Grantor of its intention to do so, to notify the obligors
with respect to any such amounts of the existence of the security interest
created hereby and to direct such obligors to make payment of all such

                                  EXHIBIT I-17
<PAGE>

amounts directly to Secured Party, and, upon such notification and at the
expense of Grantor, 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 Grantor might have done. After receipt by any Grantor of the
notice from Secured Party referred to in the proviso to the preceding sentence
and during the continuation of any Event of Default, (i) all amounts and
proceeds (including checks and other instruments) received by Grantor in respect
of amounts due to Grantor in respect of the Collateral or any portion thereof
shall be received in trust for the benefit of Secured Party hereunder, shall be
segregated from other funds of Grantor 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 (ii) Grantor 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.

          (c) Applications and Registrations.  Each Grantor shall have the duty
              ------------------------------
diligently, through counsel reasonably acceptable to Secured Party, to
prosecute, file and/or make, unless and until Grantor, in its commercially
reasonable judgment, decides otherwise, (i) any application relating to any of
the Intellectual Property owned by Grantor and identified on Schedule 1.1(b),
that is pending as of the date of this Agreement, (ii) any registration on any
existing or future unregistered but copyrightable works, (iii) application on
any existing patent or future patentable but unpatented invention comprising
Intellectual Property, and (iv) any Trademark opposition and cancellation
proceedings, renew Trademark registrations and Copyright registrations and do
any and all acts which are necessary or desirable, as determined in such
Grantor's commercially reasonable judgment, to preserve and maintain all rights
in all Intellectual Property.  Any expenses incurred in connection therewith
shall be borne solely by Grantor.  Subject to the foregoing, Grantor shall give
Secured Party prior written notice of any abandonment of any Intellectual
Property or any right to file a patent application or any pending patent
application or any Patent.

          (d) Litigation.  Except as provided herein, each Grantor shall have
              ----------
the right to commence and prosecute in its own name, as real party in interest,
for its own benefit and at its own expense, such suits, proceedings or other
actions for infringement, unfair competition, dilution, misappropriation  or
other damage, or reexamination or reissue proceedings as are in its commercially
reasonable judgment necessary to protect the Intellectual Property Collateral.
Secured Party shall provide, at Grantor's expense, all reasonable and necessary
cooperation in connection with any such suit, proceeding or action including,
without limitation, joining as a necessary party.  Each Grantor shall promptly,
following its becoming aware thereof, notify Secured Party of the institution
of, or of any adverse determination in, any proceeding (whether in the United
States Patent and Trademark Office, the United States Copyright Office or any
federal, state, local or foreign court) or regarding Grantor's ownership, right
to use, or interest in any Intellectual Property Collateral.  Grantor shall
provide to Secured Party any information with respect thereto requested by
Secured Party.

          (e) Certain Rights of Secured Party.  In addition to, and not by way
              -------------------------------
of limitation of, the granting of a security interest in the Collateral pursuant
hereto, each Grantor,

                                  EXHIBIT I-18
<PAGE>

effective upon the occurrence and during the continuation of an Event of Default
and upon written notice from Secured Party, shall grant, sell, convey, transfer,
assign and set over to Secured Party, for its benefit and the ratable benefit of
Lenders and Lender Counterparties, all of Grantor's right, title and interest in
and to the Intellectual Property Collateral to the extent necessary to enable
Secured Party to use, possess and realize on the Collateral and to enable any
successor or assign to enjoy the benefits of the Collateral. This right and
license shall inure to the benefit of Secured Party and its successors, assigns
and transferees, whether by voluntary conveyance, operation of law, assignment,
transfer, foreclosure, deed in lieu of foreclosure or otherwise. Such right and
license shall be granted free of charge, without requirement that any monetary
payment whatsoever be made to such Grantor. In addition, each Grantor hereby
grants to Secured Party and its employees, representatives and agents the right
to visit Grantor's and any of its Affiliate's or subcontractor's plants,
facilities and other places of business that are utilized in connection with the
manufacture, production, inspection, storage or sale of products and services
sold or delivered under any of the Intellectual Property Collateral (or which
were so utilized during the prior six month period), and to inspect the quality
control and all other records relating thereto upon reasonable advance written
notice to Grantor and at reasonable dates and times and as often as may be
reasonably requested. If and to the extent that any Grantor is permitted to
license the Intellectual Property Collateral, Secured Party shall promptly enter
into a non-disturbance agreement or other similar arrangement, at Grantor's
request and expense, with Grantor and any licensee of any Intellectual Property
Collateral permitted hereunder in form and substance reasonably satisfactory to
Secured Party pursuant to which (i) Secured Party shall agree not to disturb or
interfere with such licensee's rights under its license agreement with Grantor
so long as such licensee is not in default thereunder, and (ii) such licensee
shall acknowledge and agree that the Intellectual Property Collateral licensed
to it is subject to the security interest created in favor of Secured Party and
the other terms of this Agreement.

     5.4.  Equipment and Inventory.  Each Grantor shall:

               (a)  keep the Equipment and Inventory in the jurisdictions
specified on Schedule 5.4 or, upon 30 days' written notice to Secured Party, in
such other jurisdictions where all action that Secured Party may reasonably
request, in order to perfect 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 such Equipment and
Inventory shall have been taken but no Grantor shall be required to obtain a
Lessor Waiver and Consent Agreement except to the extent required under Section
5.8 of the Credit Agreement;

               (b)  provide information as to the kind, type and quantity of
Inventory, such Grantor's cost therefor and (where applicable) the current list
prices for the Inventory, in each case, in reasonable detail; and

               (c)  if any Inventory is in possession or control of any of such
Grantor's agents or processors, upon the occurrence and during the continuance
of an Event of Default, instruct such agent or processor to hold all such
Inventory for the account of Secured Party and subject to the instructions of
Secured Party.

                                  EXHIBIT I-19
<PAGE>

     5.5.  Accounts and Related Contracts.  Each Grantor shall:

               (a)  keep its chief place of business and chief executive office
and the office where it keeps its records concerning the Accounts and Related
Contracts, and all originals of all chattel paper that evidence Accounts, at the
location therefor specified on Schedule 5.5 or, upon 30 days' written notice to
Secured Party following any change in location, at such other location in a
jurisdiction where all action that Secured Party may request, in order to
perfect 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 such Accounts and Related Contracts shall
have been taken. Promptly upon the reasonable request of Secured Party, such
Grantor shall deliver to Secured Party complete and correct copies of each
Related Contract;

               (b)  maintain (i) complete and accurate records of all Accounts,
including records of all payments received, credits granted and merchandise
returned, and (ii) all documentation relating thereto in accordance with prudent
business practices;

               (c)  except as otherwise provided in this subsection (c),
continue to collect, at its own expense, all amounts due or to become due to
such Grantor under the Accounts and Related Contracts, and in connection with
such collections, such Grantor shall take such action (unless the Grantor has
determined in the exercise of its commercially reasonable judgment that it shall
not do so) as such Grantor or Secured Party may deem necessary or advisable to
enforce collection of amounts due or to become due under the Accounts; provided,
Secured Party shall have the right at any time, upon the occurrence and during
the continuation of an Event of Default and upon written notice to such Grantor
of its intention to do so, to notify the account debtors or obligors under any
Accounts of the assignment of such Accounts to Secured Party and to direct such
account debtors or obligors to make payment of all amounts due or to become due
to such Grantor thereunder directly to Secured Party, to notify each Person
maintaining a lockbox or similar arrangement to which account debtors or
obligors under any Accounts have been directed to make payment to remit all
amounts representing collections on checks and other payment items from time to
time sent to or deposited in such lockbox or other arrangement directly to
Secured Party and, upon such notification and at the expense of such Grantor, to
enforce collection of any such Accounts and to adjust, settle or compromise the
amount or payment thereof, in the same manner and to the same extent as such
Grantor might have done. After receipt by any Grantor of the notice from Secured
Party referred to in the proviso to the preceding sentence, (i) any payments of
Accounts, received by such Grantor shall be forthwith (and in any event within
two Business Days) deposited by such Grantor in the exact form received, duly
indorsed by such Grantor to the Secured Party if required, in a collateral
account maintained under the sole dominion and control of the Secured Party (the
"Collateral Account"), (ii) until so turned over in accordance with the
preceding subsection (i) all amounts and proceeds (including checks and other
instruments) received by such Grantor in respect of the Accounts and the Related
Contracts shall be received in trust for the benefit of Secured Party hereunder
and shall be segregated from other funds of such Grantor and (iii) such Grantor
shall not adjust,
                                  EXHIBIT I-20
<PAGE>

settle or compromise the amount or payment of any Account, or release wholly or
partly any account debtor or obligor thereof, or allow any credit or discount
thereon.


6.   SECURED PARTY APPOINTED ATTORNEY-IN-FACT

          Each Grantor hereby irrevocably appoints Secured Party (such
appointment being coupled with an interest) as Grantor's attorney-in-fact, with
full authority in the place and stead of Grantor and in the name of Grantor,
Secured Party or otherwise, from time to time in Secured Party's discretion to
take any action and to execute any instrument that Secured Party may deem
reasonably necessary or advisable to accomplish the purposes of this Agreement,
including (a) to obtain and adjust insurance required to be maintained by
Grantor or paid to Secured Party pursuant to the Credit Agreement; (b) upon the
occurrence and during the continuation 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 continuation 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; (d) upon the
occurrence and during the continuation of any Event of Default, to file any
claims or take any action or institute any proceedings that Secured Party may
deem 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 pay or discharge taxes or Liens (other than Liens permitted
under this Agreement or the Credit Agreement) levied or placed upon or
threatened against the Collateral, the legality or validity thereof and the
amounts necessary to discharge the same to be determined by Secured Party in its
sole discretion, any such payments made by Secured Party to become Secured
Obligations of Grantor to Secured Party, due and payable immediately without
demand; and (f) upon the occurrence and during the continuation of an Event of
Default, 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 Grantor's expense, at any time or from time to time,
all acts and things that Secured Party deems reasonably 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 Grantor might do.


7.   REMEDIES

          7.1.  Generally.  If any Event of Default shall have occurred and be
continuing, 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, all the rights and remedies of a secured party on default under the UCC
(whether or not the UCC applies to the affected Collateral), and also may (a)
require any Grantor to, and each Grantor hereby agrees that it will 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

                                  EXHIBIT I-21
<PAGE>

Secured Party that is reasonably convenient to both parties; (b) enter onto the
property where any Collateral is located and take possession thereof with or
without judicial process; (c) 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; (d) without notice except as specified below, sell 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 (e) exercise
dominion and control over, and refuse to permit further withdrawals (whether of
money, securities, instruments or other property) from any deposit account
maintained with Secured Party constituting part of the Collateral. Secured Party
or any Lender may be the purchaser of any or all of the Collateral at any such
sale and Secured Party, as agent for and representative of Lenders and Lender
Counterparties (but not any Lender or Lenders in its or their respective
individual capacities unless Requisite Lenders shall otherwise agree in
writing), 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 public sale, 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 Grantor, and each
Grantor 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 Grantor agrees that, to the extent notice of sale shall be required by law,
at least ten days' notice to Grantor of the time and place of any public sale or
the time after which any private sale is to be made shall constitute reasonable
notification. 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 Grantor 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, Grantors shall be liable
for the deficiency and the fees of any attorneys employed by Secured Party to
collect such deficiency. Each Grantor 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 Grantor, and Grantor hereby
waives and agrees not to assert any defenses against an action for specific
performance of such covenants except for a defense that no 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.

                                  EXHIBIT I-22
<PAGE>

     7.2.  Investment Property. Each Grantor 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. Each Grantor
acknowledges that any such private sales may be at prices and on terms less
favorable than those obtainable through a public sale without such restrictions
(including a public offering made pursuant to a registration statement under the
Securities Act) and, notwithstanding such circumstances each Grantor agrees that
any such private sale shall be deemed to have been made in a commercially
reasonable manner 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 Grantor shall and
shall cause each issuer of any Pledged Stock to be sold hereunder, each
Partnership and each LLC 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 interest, 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.

     7.3.  Intellectual Property Collateral.

                                  EXHIBIT I-23
<PAGE>

          (a)  Anything contained herein to the contrary notwithstanding, upon
the occurrence and during the continuation of an Event of Default, (i) Secured
Party shall have the right (but not the obligation) to bring suit, in the name
of any Grantor, Secured Party or otherwise, in Secured Party's sole discretion,
to enforce any Intellectual Property, in which event Grantor 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 Grantor shall
promptly, upon demand, reimburse and indemnify Secured Party as provided in
Section 11 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 as provided in this Section, each Grantor
agrees to use all reasonable measures, whether by action, suit, proceeding or
otherwise, to prevent the infringement of any of the Intellectual Property by
others and for that purpose agrees (based on its reasonable business judgment)
to diligently maintain any action, suit or proceeding against any Person so
infringing necessary to prevent such infringement; (ii) upon written demand from
Secured Party, each Grantor shall execute and deliver to Secured Party an
assignment or assignments of the Intellectual Property and such other documents
as are necessary or appropriate to carry out the intent and purposes of this
Agreement; (iii) each Grantor agrees that such an assignment and/or recording
shall be applied to reduce the Secured Obligations outstanding only to the
extent that Secured Party (or any Lender) receives cash proceeds in respect of
the sale of, or other realization upon, the Intellectual Property; and (iv)
within five Business Days after written notice from Secured Party, each Grantor
shall make available to Secured Party, to the extent within such Grantor's power
and authority, such personnel in each Grantor's employ on the date of such Event
of Default as Secured Party may reasonably designate, by name, title or job
responsibility, to permit such Grantor to continue, directly or indirectly, to
produce, advertise and sell the products and services sold or delivered by such
Grantor under or in connection with the Trademarks, such persons to be available
to perform their prior functions on Secured Party's behalf and to be compensated
by Secured Party at such Grantor's expense on a per diem, pro-rata basis
consistent with the salary and benefit structure applicable to each as of the
date of such Event of Default.

          (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 to Secured Party of any rights, title and interests in and to the
Intellectual Property shall have been previously made and shall have become
absolute and effective, and (iv) the Secured Obligations shall not have become
immediately due and payable, upon the written request of Grantor, Secured Party
shall promptly execute and deliver to Grantor, at Grantor's sole cost and
expense, such assignments as may be necessary to reassign to Grantor 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 all Liens other than Permitted Liens.

                                  EXHIBIT I-24
<PAGE>

          7.4. Accounts. In addition to the rights of the Secured Party
specified in Section 5.5 hereof with respect to payments of Accounts, if an
Event of Default shall occur and be continuing, upon request of the Secured
Party, all proceeds received by any Grantor consisting of cash, checks and other
near-cash items shall be held by such Grantor in trust for the Secured Party,
segregated from other funds of such Grantor, and shall, forthwith upon receipt
by such Grantor, be turned over to the Secured Party in the exact form received
by such Grantor (duly indorsed by such Grantor to Secured Party, if required)
and held by the Secured Party in the Collateral Account. All proceeds while held
by the Secured Party in trust for the Secured Party shall continue to be held as
collateral security for all the Obligations and shall not constitute payment
thereof until applied as provided in Section 7.5.

          7.5. Application of Proceeds. Except as expressly provided elsewhere
in this Agreement, all proceeds received by Secured Party in respect of any sale
of, collection from, or other realization upon all or any part of the Collateral
shall be applied as provided in Section 2.15 of the Credit Agreement.


8.   AGENT

          Secured Party has been appointed to act as agent hereunder by and on
behalf of Lenders and Lender Counterparties. Secured Party shall be obligated,
and shall have the right hereunder, to make demands, to give notices, to
exercise or refrain from exercising any rights, and to take or refrain from
taking any action (including, without limitation, the release or substitution of
Collateral), solely in accordance with this Agreement and the other Credit
Documents.


9.   CONTINUING SECURITY INTEREST; TRANSFER OF LOANS

          This Agreement shall create a continuing security interest in the
Collateral and shall (a) remain in full force and effect until the payment in
full of the Secured Obligations and the cancellation or termination of the
Commitments, (b) be binding upon each Grantor, its successors and assigns, and
(c) 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 clause (c), but subject to the
terms of the Credit Agreement, any Lender may assign or otherwise transfer any
Loans held by it to any other Person, and such other Person shall thereupon
become vested with all the benefits in respect thereof granted to Lenders herein
or otherwise.  Upon the payment in full of all Secured Obligations then owing
and the cancellation or termination of the Commitments, the security interest
granted hereby shall terminate hereunder and of record and all rights to the
Collateral shall revert to Grantor.  Upon any such termination Secured Party
will, at Grantors' expense, execute and deliver to Grantors such documents as
Grantors shall reasonably request to evidence such termination.

                                  EXHIBIT I-25
<PAGE>

10.  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. If any Grantor 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 Grantor under Section 11 of
this Agreement.


11.  INDEMNITY AND EXPENSES

          Each Grantor agrees:

               (a)  to indemnify, defend and hold harmless Secured Party, its
affiliates and its affiliates' respective directors, officers, employees, agents
and representatives from and against any and all claims, losses and liabilities
in any way relating to, growing out of or resulting from this Agreement and the
transactions contemplated hereby (including without limitation enforcement of
this Agreement), except to the extent such claims, losses or liabilities result
from Secured Party's gross negligence, bad faith, or willful misconduct as
determined by a court of competent jurisdiction in a final, non-appealable
judgment or order; and

               (b)  to pay to Secured Party promptly following written demand
(together with appropriate supporting documentation) the amount of any and all
reasonable costs and reasonable expenses, including the reasonable fees and
expenses of its counsel and of any experts and agents in accordance with the
terms and conditions of the Credit Agreement.

The obligations of each Grantor in this Section 11 shall survive the termination
of this Agreement and the discharge of such Grantor's other obligations under
this Agreement, the Credit Agreement and any other Credit Documents.


12.  REGULATORY APPROVALS

               (a)  Any provision contained herein to the contrary
notwithstanding, except for the security interests expressly granted herein or
therein or upon the exercise by the Secured Party of rights and remedies in
accordance herewith or therewith and pursuant to clause (b) below, upon the
occurrence and continuation of an Event of Default, this Agreement and the
Credit Agreement and the transactions contemplated hereby and thereby (i) do not
and will not

                                  EXHIBIT I-26
<PAGE>

constitute, create, or have the effect of constituting or creating, directly or
indirectly, actual or practical ownership of any Subsidiary of Company by the
Lenders, or control, affirmative or negative, direct or indirect, by the Lenders
over the management or any other aspect of the operation of any Subsidiary,
which ownership and control remain exclusively and at all times in such
Subsidiary, and (ii) do not and will not constitute the transfer, assignment, or
disposition in any manner, voluntarily or involuntarily, directly or indirectly
of any license, permit, certificate or authorization at any time issued to any
Subsidiary of Company by the FCC, any other federal, state or local regulatory
or governmental bodies applicable to or having jurisdiction over Company or any
Governmental Authority, or the transfer of control of any such Subsidiary within
the meaning of the Federal Communications Act of 1934, as amended and the
respective rules and regulations thereunder and thereof, any other federal or
state laws, rules and regulations of other operating municipality regulatory or
governmental bodies applicable to or having jurisdiction over the Company as
well as pursuant to the terms of any franchise, license or similar operating
right held by Company.

               (b)  Any provision contained herein to the contrary
notwithstanding, no action, including any foreclosure on, sale, transfer or
other disposition of, or the exercise of any right to vote or consent, shall be
taken hereunder by the Secured Party with respect to any item of the Collateral
unless and until all applicable requirements (if any) of the FCC under the
Federal Communications Act of 1934, as amended, and the respective rules and
regulations thereunder and thereof, as well as any other federal or state laws,
rules and regulations of other operating municipality regulatory or governmental
bodies applicable to or having jurisdiction over Company, have been satisfied
with respect to such action and there have been obtained such consents,
approvals and authorizations (if any) as may be required to be obtained from the
FCC, any operating municipality and any other Governmental Authority under the
terms of any franchise, license or similar operating right held by Company. It
is the intention of the parties hereto that the Liens in favor of the Secured
Party on the Collateral shall in all relevant aspects be subject to and governed
by said statutes, rules and regulations as well as the terms of any franchise,
license or similar operating right held by Company and that nothing in this
Agreement shall be construed to diminish the control exercised by Company except
in accordance with the provisions of such statutory requirements and license or
similar operating right held by Company and the obtaining in advance of any
necessary consents, approvals or authorizations pursuant thereto. Company agrees
that upon request by the Secured Party from time to time after the occurrence
and during the continuance of an Event of Default it will use its reasonable
best efforts to obtain any governmental, regulatory or third party consents,
approvals or authorizations referred to in this Section 12.


13.  MISCELLANEOUS

          Any notice required or permitted to be given under this Agreement
shall be given in accordance with Section 10.1 of the Credit Agreement. No
failure or delay on the part of Secured Party in the exercise of any power,
right or privilege hereunder or under any other Credit Document shall impair
such power, right or privilege or be construed to be a waiver of

                                  EXHIBIT I-27
<PAGE>

any default or acquiescence therein, nor shall any single or partial exercise of
any such power, right or privilege preclude other or further exercise thereof or
of any other power, right or privilege. All rights and remedies existing under
this Agreement and the other Credit Documents are cumulative to, and not
exclusive of, any rights or remedies otherwise available. In case any provision
in or obligation under this Agreement shall be invalid, illegal or unenforceable
in any jurisdiction, the validity, legality and enforceability of the remaining
provisions or obligations, or of such provision or obligation in any other
jurisdiction, shall not in any way be affected or impaired thereby. All
covenants hereunder shall be given independent effect so that if a particular
action or condition is not permitted by any of such covenants, the fact that it
would be permitted by an exception to, or would otherwise be within the
limitations of, another covenant shall not avoid the occurrence of a Default or
an Event of Default if such action is taken or condition exists. This Agreement
shall be binding upon each Grantor, its successors and assigns and inure to the
benefit of and enforceable by Secured Party and its successors and assigns. No
Grantor shall, without the prior written consent of Secured Party, assign any
right, duty or obligation hereunder. This Agreement, the Credit Agreement and
the other Credit Documents embody the entire agreement and understanding between
Grantors and Secured Party and supersede all prior agreements and understandings
between such parties relating to the subject matter hereof and thereof.
Accordingly, this Agreement, the Credit Agreement and the other Credit Documents
may not be contradicted by evidence of prior, contemporaneous or subsequent oral
agreements of the parties. There are no unwritten oral agreements between the
parties. This Agreement may be executed in one or more counterparts and by
different parties hereto in separate counterparts, each of which when so
executed and delivered shall be deemed an original, but all such counterparts
together shall constitute but one and the same instrument; signature pages may
be detached from multiple separate counterparts and attached to a single
counterpart so that all signature pages are physically attached to the same
document.

     THE PROVISIONS OF THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED UNDER
THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO THE CONFLICT OF LAWS
PRINCIPLES THEREOF (OTHER THAN SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAW OF
THE STATE OF NEW YORK AND THE MANDATORY CHOICE OF LAW PROVISIONS IN THE UCC
GOVERNING THE PERFECTION AND THE EFFECT OF PERFECTION OR NON-PERFECTION OF A
SECURITY INTEREST).
