     including the Cash Concentration Accounts, the "Pledged Accounts") only
     with banks listed on Schedule V hereto (the "Pledged Account Banks"). Each
     Pledged Account Bank listed on Part A of Schedule V hereto has agreed, and
     each Grantor will cause each Pledged Account Bank listed on Part B of
     Schedule V hereto to agree, within 30 days of the Closing Date, in each
     case in a record authenticated by such Grantor, the Collateral Agent and
     such Pledged Account Bank, to (1) comply with instructions originated by
     the Collateral Agent directing the disposition of funds in the respective
     Pledged Accounts without the further consent of such Grantor and (2) waive
     or subordinate in favor of the Collateral Agent all claims of such Pledged
     Account Bank (including claims by way of a security interest, right of
     setoff or right of recoupment) to such Pledged Accounts, which
     authenticated record shall be in form and substance satisfactory to the
     Collateral Agent (a "Pledged Account Letter").

               (b)  Each Grantor will (i) immediately upon the request of the
     Collateral Agent after the occurrence and during the continuance of a
     Default, instruct each Person obligated at any time to make any payment to

     Pledged Account of such Grantor or to a Cash Concentration Account and (ii)
     deposit in a Pledged Account of such Grantor or a Cash Concentration
     Account or pay to the Collateral Agent for deposit in a Cash Concentration
     Account, at the end of each Business Day, all proceeds of Collateral and
     all other cash of such Grantor.

               (c)  Concurrently with or promptly after entering into a Pledged
     Account Letter with any Pledged Account Bank, each Grantor will instruct
     such Pledged Account Bank to transfer to the applicable Cash Concentration
     Account, at the end of each Business Day (or in the case of Pledged Account
     Banks listed on Part C of Schedule V, each week, or at such interval at set
     forth in Part C), in same day funds, an amount equal to the credit balance
     of each Pledged Account (other than a Cash Concentration Account) in such
     Pledged Account Bank. If any Grantor shall fail to give any such
     instructions to any Pledged Account Bank, the Collateral Agent may do so
     without further notice to any Grantor.

     received at least 10 days' prior written notice of such addition and shall
     have received a Pledged Account Letter authenticated by such new Pledged
     Account Bank and such Grantor or a supplement to an existing Pledged
     Account Letter covering such new Pledged Account, as the case may be (and,
     upon the receipt by the Collateral Agent of such Pledged Account Letter or
     supplement thereto, Schedule V hereto shall be automatically amended to
     include such Pledged Account Bank or Pledged Account). Each Grantor agrees
     that it will not terminate any bank as a Pledged Account Bank or terminate
     any account as a Pledged Account, except that any Grantor may terminate a
     Pledged Account, and terminate a bank as a Pledged Account Bank with
     respect to such Pledged Account if it gives the Collateral Agent at least
     10 days' prior written notice of such termination (and, upon such
     termination, Schedule V hereto shall be automatically amended to delete
     such Pledged Account Bank or Pledged Account). Each Grantor agrees that it
     will not amend, modify or supplement any standing instructions with any
     Pledged Account Bank pursuant to which funds are transferred from any
     Pledged Account maintained with such Pledged Account Bank without the prior
     written approval of the Collateral Agent.

               (e)  Upon any termination of any Pledged Account Letter or other
     agreement with respect to the maintenance of a Pledged Account by any
     Grantor or any Pledged Account Bank with respect thereto, such Grantor will
     immediately notify all Obligors that were making payments to such Pledged
     Account to make all future payments to another Pledged Account listed in
     Schedule V or to a Cash Concentration Account. Each Grantor agrees to
     terminate any or all Pledged Accounts and Pledged Account Letters upon
     request by the Collateral Agent.

               (f)  So long as no Event of Default shall have occurred and be
     continuing, (i) each Borrower will draw checks on, and otherwise withdraw
     amounts only from a Cash Concentration Account in such amounts as may be
     required in the ordinary course of business (including, without limitation,
     withdrawals by Staffing Concepts of Florida, Inc. acting on behalf of one
     or more Davel Credit Parties pursuant to the employee leasing agreement and
     the Authorization Agreement For Direct Deposits (ACH Debts), dated December
     14, 2001, between Staffing Concepts of Florida, Inc. and Telaleasing
     Enterprises, Inc.) and (ii) the Collateral Agent will, to the extent funds
     are available in a Cash Concentration Account, permit the transfer of
     amounts on deposit in such Cash Concentration Account to the extent
     necessary to pay all checks drawn on, and all amounts otherwise withdrawn
     from, such Cash Concentration Account.

               (g)  Each Grantor agrees that it will not add any account as an
     unblocked account to those listed in Schedule VI hereto and will not
     terminate any account as an unblocked account, unless the Collateral Agent
     shall have received at least 10 days' prior written notice of such addition
     or termination (and, upon such addition or termination, Schedule VI hereto
     shall be automatically amended to add or delete such account, as

in order to maintain such Trademark in full force free from any claim of
abandonment for non-use, (ii) maintain as in the past the quality of products
and services offered under such Trademark, (iii) employ such Trademark with the
appropriate notice of registration, (iv) not adopt or use any mark which is
confusingly similar or a colorable imitation of such Trademark unless the
Collateral Agent, for the ratable benefit of the Lenders, shall obtain a
perfected security interest in such mark pursuant to this Security Agreement,
and (v) not (and not permit any licensee or sublicensee thereof to) do any act
or knowingly omit to do any act whereby any material Trademark may become
invalidated;

               (e) not do any act, or omit to do any act, whereby any material
Patent may become abandoned or dedicated;

               (f) promptly notify the Collateral Agent if it knows, or has
reason to know, that any application or registration relating to any material
Patent or material Trademark may become abandoned or dedicated, or of any
adverse determination or development (including, without limitation, the
institution of, or any such determination or development in, any proceeding in
the United States Patent and Trademark Office or any court or tribunal in any
country) regarding an Grantor's ownership of any such Patent or Trademark or its
right to register the same or to keep and maintain the same;

               (g) if such Grantor, either by itself or through an agent,
employee, licensee or designee, shall file an application for the registration
of any Patent or Trademark with the United States Patent and Trademark Office or
any similar office or agency in any other country or any political subdivision
thereof, such Grantor shall report such filing to the Collateral Agent within 10
Business Days after the last day of the fiscal quarter in which such filing
occurs, and

                                      15
<PAGE>

upon request of the Collateral Agent, shall execute and deliver any and all
agreements, instruments and other documents as the Collateral Agent may
reasonably request to evidence the Collateral Agent's and the Lenders' security
interest in any Patent or Trademark and the goodwill and General Intangibles of
a Grantor relating thereto or represented thereby;

               (h) take all reasonable and necessary steps, including, without
limitation, in any proceeding before the United States Patent and Trademark
Office, or any similar office or agency in any other country or any political
subdivision thereof, to maintain and pursue each application (and to obtain the
relevant registration) and to maintain each registration of all material Patents
and material Trademarks, including, without limitation, filing of applications
for renewal, affidavits of use and affidavits of incontestability;

               (i) promptly notify the Collateral Agent after it learns that any
material Patent or material Trademark included in the Collateral is infringed,
misappropriated or diluted by a third party and promptly sue for infringement,
misappropriation or dilution, seek injunctive relief where appropriate and
recover any and all damages for such infringement, misappropriation or dilution,
or take such other actions as it shall reasonably deem appropriate under the
circumstances to protect such Patent or Trademark; and

               (j) except for licenses to third parties in the ordinary course
of business, not make any assignment or agreement in conflict with the security
interest in the Patents or Trademarks, whether now or hereafter existing, of
such Grantor.

          Section 12. Regulatory Approvals. So long as any Loan or any other
                      --------------------
Obligation shall remain unpaid or any Lender shall have any Commitment under the
Credit Agreement, each Grantor shall promptly, and at its expense, execute and
deliver, or cause to be executed and delivered, all applications, certificates,
instruments, registration statements and all other documents the Collateral
Agent may reasonably request and as may be required by law in connection with
the obtaining of any FCC Consents, State Consents or the consent, approval,
registration, qualification or authorization of any other Person necessary or
deemed by the Collateral Agent to be appropriate for the effective exercise of
any of its rights under this Agreement. Without limiting the generality of the
foregoing, if an Event of Default shall have occurred and be continuing, each
Grantor shall take any action which the Collateral Agent may reasonably request
in order to transfer and assign 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, each FCC License, State License or other Government Approval of such
Grantor. To enforce the provisions of this Section 12, upon the occurrence and
during the continuance of an Event of Default, the Collateral Agent is empowered
to request the appointment of a receiver from any court of competent
jurisdiction. Such receiver shall be instructed to seek from the FCC or other
Governmental Authority an involuntary transfer of control of each such FCC
License, State License or other Governmental Approval for the purpose of seeking
a bona fide purchaser to whom control will ultimately be transferred. Each
Grantor hereby agrees to authorize such an involuntary transfer of control upon
the request of the receiver so appointed, and, if such Grantor shall refuse to
authorize the transfer, its approval may be required by the court. Upon the
occurrence and continuance of an Event of Default, such Grantor shall further
use its reasonable best efforts to assist in obtaining FCC Consents, State
Consents or other governmental approvals, if required, for any action or
transaction contemplated by this Security Agreement, including, without
limitation, the preparation, execution and filing with the FCC or other
governmental authority of

                                      16
<PAGE>

such Grantor's portion of any necessary or appropriate application for the
approval of the transfer or assignment of any portion of the assets (including
any FCC Licenses, State Licenses or other Governmental Approval) of such
Grantor. Because each Grantor agrees that the Collateral Agent's remedy at law
for failure of such Grantor to comply with the provisions of this Section 12
would be inadequate and that such failure would not be adequately compensable in
damages, such Grantor agrees that the covenants contained in this Section 12 may
be specifically enforced, and such Grantor hereby waives and agrees not to
assert any defenses against an action for specific performance of such
covenants.

          Section 13. As to Inventory and Equipment. (a) Each Grantor will keep
                      -----------------------------
the Inventory and Equipment of such Grantor (other than Inventory sold in the
ordinary course of business) at the places specified therefor in Section 9(b)
or, upon 30 days' (or such lesser period as the Collateral Agent, in its
discretion, agrees) prior written notice to the Collateral Agent, at such other
places designated by such Grantor in such notice. Upon the giving of such
notice, Schedule II hereto shall be automatically amended to add any new
locations specified in the notice.

               (b) Each Grantor will promptly furnish to the Collateral Agent a
statement respecting any material loss or damage to any of the Inventory or
Equipment of such Grantor.

               (c) Each Grantor will pay promptly when due all property and
other taxes, assessments and governmental charges or levies imposed upon, and
all claims (including, without limitation, claims for labor, materials and
supplies) against, the Inventory or Equipment of such Grantor. In producing or
distributing its Inventory, each Grantor will comply with all requirements of
applicable law, including, without limitation, any Communications Law or State
Communications Law.

          Section 14. Insurance. (a) Each Grantor will, at its own expense and
                      ---------
in addition to insurance required to be maintained by such Grantor under the
Credit Agreement, maintain insurance with respect to the Inventory and Equipment
of such Grantor in such amounts, against such risks, in such form and with such
insurers, as shall be satisfactory to the Collateral Agent from time to time.
Each policy of each Grantor for liability insurance shall provide for all losses
to be paid on behalf of the Collateral Agent and such Grantor as their interests
may appear, and each policy for property damage insurance shall provide for all
losses to be paid directly to the Collateral Agent or deposited directly into a
Cash Concentration Account. Each such policy shall in addition (i) name such
Grantor and the Collateral Agent as insured parties thereunder (without any
representation or warranty by or obligation upon the Collateral Agent) as their
interests may appear, (ii) contain the agreement by the insurer that any loss
thereunder shall be payable to the Collateral Agent notwithstanding any action,
inaction or breach of representation or warranty by such Grantor, (iii) provide
that there shall be no recourse against the Collateral Agent for payment of
premiums or other amounts with respect thereto and (iv) provide that at least 10
days' prior written notice of cancellation or of lapse shall be given to the
Collateral Agent by the insurer. Each Grantor will, if so requested by the
Collateral Agent, deliver to the Collateral Agent original or duplicate policies
of such insurance and, as often as the Collateral Agent may reasonably request,
a report of a reputable insurance broker with respect to such insurance.
Further, each Grantor will, at the request of the Collateral Agent, duly

                                      17
<PAGE>

execute and deliver instruments of assignment of such insurance policies to
comply with the requirements of Section 10 and cause the insurers to acknowledge
notice of such assignment.

               (b) Reimbursement under any liability insurance maintained by any
Grantor pursuant to this Section 14 may be paid directly to the Person who shall
have incurred liability covered by such insurance. In case of any loss involving
damage to Inventory or Equipment when subsection (c) of this Section 14 is not
applicable, the applicable Grantor will make or cause to be made the necessary
repairs to or replacements of such Inventory or Equipment, and any proceeds of
insurance properly received by or released to such Grantor shall be used by such
Grantor, except as otherwise required hereunder or by the Credit Agreement, to
pay or as reimbursement for the costs of such repairs or replacements.

               (c) So long as no Default shall have occurred and be continuing,
all insurance payments received by the Collateral Agent in connection with any
loss, damage or destruction of any Inventory or Equipment will be released by
the Collateral Agent to the applicable Grantor for the repair, replacement or
restoration thereof, subject to such terms and conditions with respect to the
release thereof as the Collateral Agent may reasonably require. To the extent
that (i) the amount of any such insurance payments exceeds the cost of any such
repair, replacement or restoration, or (ii) such insurance payments are not
otherwise required by the applicable Grantor to complete any such repair,
replacement or restoration required hereunder, the Collateral Agent will not be
required to release the amount thereof to such Grantor and may hold or continue
to hold such amount in the Collateral Account as additional security for the
Secured Obligations of such Grantor (except that the Collateral Agent will
direct the applicable Pledged Account Bank to release to such Grantor any such
amount if and to the extent that any prepayment of Obligations is required under
the Credit Agreement in connection with the receipt of such amount and such
prepayment has been made). Upon the occurrence and during the continuance of any
Default or the actual or constructive total loss of any Inventory or Equipment,
all insurance payments in respect of such Inventory or Equipment shall be
deposited directly into a Cash Concentration Account or paid to the Collateral
Agent and, if paid directly to the Collateral Agent, shall, in the Collateral
Agent's sole discretion, (i) be released to the applicable Grantor to be applied
as set forth in the first sentence of this subsection (c) or (ii) be held as
additional Collateral hereunder or applied as specified in Section 22(b).

          Section 15. Post-Closing Changes; Bailees; Collections on Assigned
                      ------------------------------------------------------
Agreements, Receivables and Related Contracts. (a) No Grantor will change its
---------------------------------------------
name, identity, corporate structure, federal tax identification number,
organizational identification number, or location from those set forth in
Section 9(a) and (b) without first giving at least 30 days' prior written notice
to the Collateral Agent and taking all action required by the Collateral Agent
for the purpose of perfecting or protecting the liens granted by this Agreement.
Each Grantor will not become bound by a security agreement signed or
authenticated by another Person (determined as provided in Section 9-203(d) of
the UCC) without giving the Collateral Agent 10 days' prior written notice
thereof and taking all action required by the Collateral Agent to insure that
the perfection and first priority nature of the Collateral Agent's lien on the
Collateral will be maintained. Each Grantor will also keep all originals of all
chattel paper that evidence Receivables of such Grantor, at the location
therefor specified in Section 9(b) or, upon 10 days' prior written notice to the
Collateral Agent, at such other location designated in such notice. Each Grantor
will hold and preserve its records relating to the Collateral and chattel paper
and

                                      18
<PAGE>

will permit representatives of the Collateral Agent at any time during normal
business hours to inspect and make abstracts from such records and other
documents.

               (b) If any of its Collateral is at any time in the possession or
control of a warehouseman, bailee or agent, or if the Collateral Agent so
requests such Grantor will (i) notify such warehouseman, bailee or agent of the
security interests, (ii) instruct such warehouseman, bailee or agent to hold all
such Collateral for the Collateral Agent's account subject to the Collateral
Agent's instructions (which shall permit such Collateral to be removed by such
Grantor in the ordinary course of business until the Collateral Agent notifies
such warehouseman, bailee or agent that an Event of Default has occurred and is
continuing), (iii) using commercially reasonable efforts, cause such
warehouseman, bailee or agent to authenticate a record acknowledging that it
holds possession of such Collateral for the Collateral Agent's benefit and (iv)
make such authenticated record available to the Collateral Agent.

               (c) Except as otherwise provided in this subsection (c), each
Grantor will continue to collect, at its own expense, all amounts due or to
become due such Grantor under the Receivables (the "Pledged Receivables") and
the Related Contracts. In connection with such collections, such Grantor may
take (and, at the Collateral Agent's direction, will take) such action as such
Grantor or the Collateral Agent may deem necessary or advisable to enforce
collection of the Pledged Receivables and the Related Contracts; provided,
                                                                 --------
however, that the Collateral Agent shall have the right at any time upon the
-------
occurrence and during the continuance of a Default, upon written notice to such
Grantor of its intention to do so, to notify the Obligors under any Pledged
Receivables or Related Contracts of the assignment of such Pledged Receivables
or Related Contracts to the Collateral Agent and to direct such Obligors to make
payment of all amounts due or to become due to such Grantor thereunder directly
to the Collateral Agent and, upon such notification and at the expense of such
Grantor, to enforce collection of any such Pledged Receivables or Related
Contracts, 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, and to
otherwise exercise all rights with respect to such Pledged Receivables and
Related Contracts, including, without limitation, those set forth set forth in
Section 9-607 of the UCC. After receipt by any Grantor of the notice from the
Collateral Agent referred to in the proviso to the preceding sentence, (i) all
amounts and proceeds (including instruments) received by such Grantor in respect
of the Pledged Receivables and the Related Contracts of such Grantor shall be
received in trust for the benefit of the Collateral Agent hereunder, shall be
segregated from other funds of such Grantor and shall be forthwith paid over to
the Collateral Agent in the same form as so received (with any necessary
indorsement) to be deposited in the Collateral Account and either (A) released
to such Grantor so long as no Default shall have occurred and be continuing or
(B) if any Default shall have occurred and be continuing, applied as provided in
Section 22(b) and (ii) such Grantor will not adjust, settle or compromise the
amount or payment of any Receivable, or amount due on any Related Contract,
release wholly or partly any Obligor thereof, or allow any credit or discount
thereon. No Grantor will permit or consent to the subordination of its right to
payment under any of the Pledged Receivables and Related Contracts to any other
indebtedness or obligations of the Obligor thereof.

          Section 16. Voting Rights; Dividends; Etc. (a) So long as no Default
                      -----------------------------
shall have occurred and be continuing:

          (i)   Each Grantor shall be entitled to exercise any and all voting
     and other consensual rights pertaining to the Security Collateral of such
     Grantor or any part thereof for any purpose other than to originate
     Entitlement Orders (as defined in any Securities Account Control Agreement)
     with respect to any securities account; provided, however, that such
                                             --------  -------
     Grantor will not exercise or refrain from exercising any such right if such
     action would have a material adverse effect on the value of the Security
     Collateral or any part thereof.

          (ii)  Each Grantor shall be entitled to receive and retain any and all
     dividends, interest and other distributions paid in respect of the Security
     Collateral of such Grantor if and to the extent that the payment thereof is
     not otherwise prohibited by the terms of the Loan Documents; provided,
                                                                  --------
     however, that any and all
     -------

                (A) dividends, interest and other distributions paid or payable
          other than in cash in respect of, and instruments and other property
          received, receivable or otherwise distributed in respect of, or in
          exchange for, any Security Collateral,

                (B) dividends and other distributions paid or payable in cash in
          respect of any Security Collateral in connection with a partial or
          total liquidation or dissolution or in connection with a reduction of
          capital, capital surplus or paid-in-surplus and

                (C) cash paid, payable or otherwise distributed in respect of
          principal of, or in redemption of, or in exchange for, any Security
          Collateral

     shall be, and shall be forthwith delivered to the Collateral Agent to hold
     as, Security Collateral and shall, if received by such Grantor, be received
     in trust for the benefit of the Collateral Agent, be segregated from the
     other property or funds of such Grantor and be forthwith delivered to the
     Collateral Agent as Security Collateral in the same form as so received
     (with any necessary indorsement).

          (iii) The Collateral Agent will execute and deliver (or cause to be
     executed and delivered) to each Grantor all such proxies and other
     instruments as such Grantor may reasonably request for the purpose of
     enabling such Grantor to exercise the voting and other rights that it is
     entitled to exercise pursuant to paragraph (i) above and to receive the
     dividends or interest payments that it is authorized to receive and retain
     pursuant to paragraph (ii) above.

                (b) Upon the occurrence and during the continuance of a Default:

                (i)  All rights of each Grantor (x) to exercise or refrain from
     exercising the voting and other consensual rights that it would otherwise
     be entitled to exercise pursuant to Section 16(a)(i) shall, upon notice to
     such Grantor by the Collateral Agent, cease and (y) to receive the
     dividends, interest and other distributions that it would otherwise be
     authorized to receive and retain pursuant to Section 16(a)(ii) shall

                                      20
<PAGE>

     automatically cease, and all such rights shall thereupon become vested in
     the Collateral Agent, which shall thereupon have the sole right to exercise
     or refrain from exercising such voting and other consensual rights and to
     receive and hold as Security Collateral such dividends, interest and other
     distributions.

               (ii)  All dividends, interest and other distributions that are
     received by any Grantor contrary to the provisions of paragraph (i) of this
     Section 16(b) shall be received in trust for the benefit of the Collateral
     Agent, shall be segregated from other funds of such Grantor and shall be
     forthwith paid over to the Collateral Agent as Security Collateral in the
     same form as so received (with any necessary indorsement).

               (iii) The Collateral Agent shall be authorized to send to each
     Securities Intermediary as defined in and under any Securities Account
     Control Agreement a Notice of Exclusive Control as defined in and under
     such Securities Account Control Agreement.

          Section 17. As to Letter-of-Credit Rights. (a) Each Grantor, by
                      ------------------------------
granting a security interest in its Letter-of-Credit Rights to the Collateral
Agent, intends to (and hereby does) assign to the Collateral Agent its rights
(including its contingent rights) to the proceeds of all letters of credit of
which it is or hereafter becomes a beneficiary. Each Grantor will promptly cause
the issuer of such letter of credit and each nominated person (if any) with
respect thereto to consent to such assignment of the proceeds thereof and
deliver written evidence of such consent to the Collateral Agent.

               (b) If an Event of Default shall have occurred and be continuing,
each Grantor will, promptly upon request by the Collateral Agent, notify (and
such Grantor hereby authorizes the Collateral Agent to notify) the issuer and
each nominated person with respect to each of its pledged letters of credit that
(i) the proceeds thereof have been assigned to the Collateral Agent hereunder
and (ii) any payments due or to become due in respect thereof are to be made
directly to the Collateral Agent or its designee.

          Section 18. Transfers and Other Liens; Additional Shares. (a) Each
                      --------------------------------------------
Grantor agrees that it will not (i) sell, assign or otherwise dispose of, or
grant any option with respect to, any of the Collateral, other than sales,
assignments and other dispositions of Collateral, and options relating to
Collateral, permitted under the terms of the Credit Agreement, or (ii) create or
suffer to exist any Lien upon or with respect to any of the Collateral of such
Grantor except for the pledge, assignment and security interest created under
this Agreement and Liens permitted under the Credit Agreement.

               (b) Each Grantor agrees that it will (i) cause each issuer of the
Pledged Shares pledged by such Grantor not to issue any stock or other
securities in addition to or in substitution for the Pledged Shares issued by
such issuer, except to such Grantor, and (ii) pledge hereunder, immediately upon
its acquisition (directly or indirectly) thereof, any and all additional shares
of stock or other securities of each issuer of the Pledged Shares.

          Section 19. Collateral Agent Appointed Attorney-in-Fact. Each Grantor
                      -------------------------------------------
hereby irrevocably appoints the Collateral Agent such Grantor's attorney-in-
fact, with full

                                      21
<PAGE>

authority in the place and stead of such Grantor and in the name of such Grantor
or otherwise, from time to time in the Collateral Agent's discretion, to take
any action and to execute any instrument that the Collateral Agent may deem
necessary or advisable to accomplish the purposes of this Agreement. Such
actions shall include each of the following, but only after the occurrence and
during the continuance of an Event of Default.

               (a) to obtain and adjust insurance required to be paid to the
     Collateral Agent pursuant to Section 14,

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

               (c) to receive, indorse and collect any drafts or other
     instruments, documents and chattel paper, in connection with clause (a) or
     (b) above, and

               (d) to file any claims or take any action or institute any
     proceedings that the Collateral Agent may deem necessary or desirable for
     the collection of any of the Collateral or otherwise to enforce compliance
     with the rights of the Collateral Agent with respect to any of the
     Collateral.

          Section 20. Collateral Agent May Perform. If any Grantor fails to
                      ----------------------------
perform any agreement contained herein, the Collateral Agent may, as the
Collateral Agent deems necessary to protect the security interest granted
hereunder in the Collateral or to protect the value thereof, but without any
obligation to do so and without notice, itself perform, or cause performance of,
such agreement, and the expenses of the Collateral Agent incurred in connection
therewith shall be payable by such Grantor under Section 23(b).

          Section 21. The Collateral Agent's Duties. (a) The powers conferred
                      -----------------------------
on the Collateral Agent hereunder are solely to protect the Lenders' interest in
the Collateral and shall not impose any duty upon it to exercise any such
powers. Except for the exercise of reasonable care with respect to the safe
custody of any Collateral in its possession and the accounting for moneys
actually received by it hereunder, the Collateral Agent shall have no duty or
liability as to any Collateral, as to ascertaining or taking action with respect
to calls, conversions, exchanges, maturities, tenders or other matters relative
to any Collateral, whether or not the Collateral Agent or any Lender has or is
deemed to have knowledge of such matters, or as to the taking of any necessary
steps to preserve rights against any parties or any other rights pertaining to
any Collateral. The Collateral Agent shall be deemed to have exercised
reasonable care in the custody and preservation of any Collateral in its
possession if such Collateral is accorded treatment substantially equal to that
which it accords its own property.

               (b) Anything contained herein to the contrary notwithstanding,
the Collateral Agent may from time to time, when the Collateral Agent deems it
to be necessary, appoint one or more subagents (each a "Subagent") for the
Collateral Agent hereunder with respect to all or any part of the Collateral. In
the event that the Collateral Agent so appoints any Subagent with respect to any
Collateral, (i) the assignment and pledge of such Collateral and the security
interest granted in such Collateral by each Grantor hereunder shall be deemed
for

                                      22
<PAGE>

purposes of this Security Agreement to have been made to such Subagent, in
addition to the Collateral Agent, for the ratable benefit of the Lenders, as
security for the Secured Obligations of such Grantor, (ii) such Subagent shall
automatically be vested, in addition to the Collateral Agent, with all rights,
powers, privileges, interests and remedies of the Collateral Agent hereunder
with respect to such Collateral and (iii) the term "Collateral Agent," when used
herein in relation to any rights, powers, privileges, interests and remedies of
the Collateral Agent with respect to such Collateral, shall include such
Subagent; provided, however, that no such Subagent shall be authorized to take
          --------  -------
any action with respect to any such Collateral unless and except to the extent
expressly authorized in writing by the Collateral Agent.

               (c) Notwithstanding anything herein to the contrary, to the
extent this Security Agreement or any other Credit Document purports to require
any Grantor to grant to the Collateral Agent, on behalf of the Lenders, a
security interest in the FCC Licenses or State Licenses of such Grantor, the
Collateral Agent, on behalf of the Lenders, shall only have a security interest
in such licenses at such times and to the extent that a security interest in
such licenses is permitted under applicable law. In further recognition of
applicable FCC or State rules and policies, the parties hereto also agree that,
notwithstanding anything to the contrary contained in this Security Agreement or
any other Credit Document, the Collateral Agent, on behalf of the Lenders, will
not take any action pursuant to this Security Agreement or any other Credit
Document that would constitute or result in any assignment of a FCC License or a
State License or any transfer of control of a Grantor if such assignment of
license or transfer of control would require under then-existing law (including
any Communications Law or State Communications Law) prior FCC Consents or State
Consents without first obtaining such FCC Consents or State Consents.

               (d) The Collateral Agent may release any of the Collateral from
this Agreement or may substitute any of the Collateral for other Collateral
without altering, varying or diminishing in any way the force, effect, lien,
pledge or security interest of this Agreement as to any Collateral not expressly
released or substituted, and this Security Agreement shall continue as a first
priority lien, subject to Permitted Liens, on all Collateral not expressly
released or substituted.

          Section 22. Remedies. If any Event of Default shall have occurred and
                      --------
be continuing:

          (a) The Collateral Agent may exercise in respect of the Collateral, in
     addition to other rights and remedies provided for herein or otherwise
     available to it, all the rights and remedies of a secured party upon
     default under the UCC (whether or not the UCC applies to the affected
     Collateral) and also may: (i) require each Grantor to, and each Grantor
     hereby agrees that it will at its expense and upon request of the
     Collateral Agent forthwith, assemble all or part of the Collateral as
     directed by the Collateral Agent and make it available to the Collateral
     Agent at a place and time to be designated by the Collateral Agent that is
     reasonably convenient to both parties; (ii) 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 the Collateral Agent's offices
     or elsewhere, for cash, on credit or for future delivery, and upon such
     other terms as the Collateral Agent may deem commercially reasonable; (iii)
     occupy any premises owned or leased by any of the Grantors where the
     Collateral or any part thereof is assembled or located for a reasonable
     period in order to effectuate its rights and remedies hereunder or under
     law, without

                                      23
<PAGE>

     obligation to such Grantor in respect of such occupation; and (iv) exercise
     any and all rights and remedies of any of the Grantors under or in
     connection with the Collateral or otherwise in respect of the Collateral,
     including, without limitation, (A) any and all rights of such Grantor to
     demand or otherwise require payment of any amount under, or performance of
     any provision of, the Pledged Receivables and the Related Contracts and the
     other Collateral, (B) withdraw, or cause or direct the withdrawal, of all
     funds with respect to the Account Collateral and (C) exercise all other
     rights and remedies with respect to the Pledged Receivables, the Related
     Contracts and the other Collateral, including, without limitation, those
     set forth in Section 9-607 of the UCC. Each Grantor agrees that, to the
     extent notice of sale shall be required by law, at least 10 days' notice to
     such Grantor of the time and place of any public sale or the time after
     which any private sale is to be made shall constitute reasonable
     notification. The Collateral Agent shall not be obligated to make any sale
     of Collateral regardless of notice of sale having been given. The
     Collateral Agent may adjourn any public or private sale from time to time
     by announcement at the time and place fixed therefor, and such sale may,
     without further notice, be made at the time and place to which it was so
     adjourned.

          (b)  Any cash held by or on behalf of the Collateral Agent and all
     cash proceeds received by or on behalf of the Collateral Agent in respect
     of any sale of, collection from, or other realization upon all or any part
     of the Collateral may, in the discretion of the Collateral Agent, be held
     by the Collateral Agent as collateral for, and/or then or at any time
     thereafter applied (after payment of any amounts payable to the Collateral
     Agent pursuant to Section 23) in whole or in part by the Collateral Agent
     for the ratable benefit of the Lenders against, all or any part of the
     Secured Obligations, in the following manner:

                    (i)   first, to the payment of all of the fees,
                          -----
          indemnification payments, costs and expenses that are due and payable
          to the Collateral Agent under or in respect of the Loan Documents on
          such date;

                    (ii)  second, to the payment of all of the indemnification
                          ------
          payments, fees, costs and expenses that are due and payable to the
          Lenders under Section 23, Section 8.06 of the Credit Agreement and any
          similar section of any of the other Loan Documents on such date,
          ratably based upon the respective aggregate amounts of all such
          indemnification payments, costs and expenses owing to the Lenders on
          such date;

                    (iii) third, to the payment of all of the accrued and unpaid
                          -----
          interest on the Obligations (other than the Loans) that is due and
          payable to the and the Lenders under Section 2.03 of the Credit
          Agreement on such date, ratably based upon the respective aggregate
          amounts of all such interest owing to the Lenders on such date;

                    (iv)  fourth, to the payment of all of the accrued and
                          ------
          unpaid interest on the Loans that is due and payable to the Lenders
          under Section 2.03 of the Credit Agreement on such date, ratably based
          upon the respective aggregate amounts of all such interest owing to
          the Lenders on such date;

                                      24
<PAGE>

                    (v)   fifth, to the payment of the principal of all of the
                          -----
          outstanding Loans that is due and payable to the Lenders on such date,
          ratably based upon the respective aggregate amounts of all such
          principal owing to the Lenders on such date; and

                    (vi)  sixth, to the payment of all other Obligations of the
                          -----
          Loan Parties owing under or in respect of the Loan Documents that are
          due and payable to the Lenders on such date, ratably based upon the
          respective aggregate amounts of all such Obligations owing to the
          Lenders on such date.

Any surplus of such cash or cash proceeds held by or on the behalf of the
Collateral Agent and remaining after payment in full of all the Secured
Obligations shall be paid over to the applicable Grantor or to whomsoever may be
lawfully entitled to receive such surplus.

               (c)  Unless the Collateral Agent has elected to retain the
     Collateral pursuant to the applicable provisions of the UCC, in the event
     that the proceeds of any sale, collection or realization are insufficient
     to pay all amounts to which the Collateral Agent or the Lenders are
     entitled as set forth above, the Grantors shall be jointly and severally
     liable for the deficiency, together with interest thereon at the rate
     specified in Section 2.03 of the Credit Agreement, together with the costs
     of collection and the reasonable fees of any attorneys employed by the
     Collateral Agent to collect such deficiency.

               (d)  All payments received by any Grantor in respect of the
     Collateral shall be received in trust for the benefit of the Collateral
     Agent, shall be segregated from other funds of such Grantor and shall be
     forthwith paid over to the Collateral Agent in the same form as so received
     (with any necessary indorsement).

               (e)  The Collateral Agent may, without notice to any Grantor
     except as required by law and at any time or from time to time, charge,
     set-off and otherwise apply all or any part of the Secured Obligations
     against any funds held with respect to the Account Collateral or in any
     other deposit account.

               (f)  If the Collateral Agent shall determine to exercise its
     right to sell all or any of the Security Collateral of any Grantor pursuant
     to this Section 22, each Grantor agrees that, upon request of the
     Collateral Agent, such Grantor will, at its own expense:

                    (i)   execute and deliver, and cause each issuer of such
          Security Collateral contemplated to be sold and the directors and
          officers thereof to execute and deliver, all such instruments and
          documents, and do or cause to be done all such other acts and things,
          as may be necessary or, in the opinion of the Collateral Agent,
          advisable to register such Security Collateral under the provisions of
          the Securities Act of 1933 (as amended from time to time, the
          "Securities Act"), to cause the registration statement relating
          thereto to become effective and to remain effective for such period as
          prospectuses are required by law to be furnished and to make all
          amendments and supplements thereto and to the related prospectus that,
          in the opinion of the Collateral Agent, are necessary or advisable,
          all in conformity with the requirements of the Securities Act and the

                                      25
<PAGE>

          rules and regulations of the Securities and Exchange Commission
          applicable thereto;

                    (ii)  use its best efforts to qualify the Security
          Collateral under the state securities or "Blue Sky" laws and to obtain
          all necessary governmental approvals for the sale of such Security
          Collateral, as requested by the Collateral Agent;

                    (iii) cause each such issuer of such Security Collateral to
          make available to its security holders, as soon as practicable, an
          earnings statement that will satisfy the provisions of Section 11(a)
          of the Securities Act;

                    (iv)  provide the Collateral Agent with such other
          information and projections as may be necessary or, in the opinion of
          the Collateral Agent, advisable to enable the Collateral Agent to
          effect the sale of such Security Collateral; and

                    (v)   do or cause to be done all such other acts and things
          as may be necessary to make such sale of such Security Collateral or
          any part thereof valid and binding and in compliance with applicable
          law.

               (g) The Collateral Agent is authorized, in connection with any
     sale of the Security Collateral pursuant to this Section 22, to deliver or
     otherwise disclose to any prospective purchaser of the Security Collateral:
     (i) any registration statement or prospectus, and all supplements and
     amendments thereto, prepared pursuant to subsection (f)(i) above; (ii) any
     information and projections provided to it pursuant to subsection (f)(iv)
     above; and (iii) any other information in its possession relating to such
     Security Collateral.

               (h) Each Grantor acknowledges the impossibility of ascertaining
     the amount of damages that would be suffered by the Lenders by reason of
     the failure by such Grantor to perform any of the covenants contained in
     subsection (f) above and, consequently, agrees that, if such Grantor shall
     fail to perform any of such covenants, it will pay, as liquidated damages
     and not as a penalty, an amount equal to the value of the Security
     Collateral on the date the Collateral Agent shall demand compliance with
     subsection (f) above.

               (i) The Grantors recognize that the Collateral Agent may deem it
     impracticable to effect a public sale of all or any part of the Security
     Collateral and that the Collateral Agent may, therefore, determine to make
     one or more private sales of any such Security Collateral to a restricted
     group of purchasers who will be obligated to agree, among other things, to
     acquire such Security Collateral for their own account, for investment and
     not with a view to the distribution or resale thereof. Each Grantor
     acknowledges that any such private sale may be at prices and on terms less
     favorable to the seller than the prices and other terms which might have
     been obtained at a public sale and, notwithstanding the foregoing, agrees
     that such private sale shall be deemed to have been made in a commercially
     reasonable manner and that the Collateral Agent shall have

                                      26
<PAGE>

     no obligation to delay sale of any such securities for the period of time
     necessary to permit the issuer of such securities to register such
     securities for public sale under the Securities Act of 1933. Each Grantor
     further acknowledges and agrees that any offer to sell Security Collateral
     which has been (i) publicly advertised on a bona fide basis in a newspaper
     or other publication of general circulation in the financial community of
     New York, New York (to the extent that such offer may be advertised without
     prior registration under the Securities Act of 1933) or (ii) made privately
     in the manner described above shall be deemed to involve a "public sale"
     under the UCC, notwithstanding that such sale may not constitute a "public
     offering" under the Securities Act of 1933, and the Collateral Agent may,
     in such event, bid for the purchase of such Security Collateral.

          Section 23. Indemnity and Expenses. (a) Each Grantor agrees to
                      ----------------------
indemnify, defend and save and hold harmless each Secured Party and each of
their Affiliates and their respective officers, directors, employees, agents and
advisors (each, an "Indemnified Party") from and against, and shall pay on
demand, any and all claims, damages, losses, liabilities and expenses
(including, without limitation, reasonable fees and expenses of counsel) that
may be incurred by or asserted or awarded against any Indemnified Party, in each
case arising out of or in connection with or resulting from this Agreement
(including, without limitation, enforcement of this Agreement), except to the
extent such claim, damage, loss, liability or expense is found in a final, non-
appealable judgment by a court of competent jurisdiction to have resulted from
such Indemnified Party's gross negligence or willful misconduct.

               (b) Each Grantor will upon demand pay to the Collateral Agent the
amount of any and all reasonable expenses, including, without limitation, the
reasonable fees and expenses of its counsel and of any experts and agents, that
the Collateral Agent may incur in connection with (i) the administration of this
Agreement, (ii) the custody, preservation, use or operation of, or the sale of,
collection from or other realization upon, any of the Collateral of such
Grantor, (iii) the exercise or enforcement of any of the rights of the
Collateral Agent or the other Lenders hereunder or (iv) the failure by such
Grantor to perform or observe any of the provisions hereof.

               (c) The foregoing indemnity shall be effective whether or not
such investigation, litigation or proceeding is brought by a Grantor, its
directors, shareholders or creditors or an Indemnified Party or any other
Person.

          Section 24. Amendments; Waivers; Additional Grantors; Etc. (a) No
                      ---------------------------------------------
amendment or waiver of any provision of this Agreement, and no consent to any
departure by any Grantor herefrom, shall in any event be effective unless the
same shall be in writing and signed by the Collateral Agent, and then such
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given. No failure on the part of the Collateral Agent
or any Lender to exercise, and no delay in exercising any right hereunder, shall
operate as a waiver thereof nor shall any single or partial exercise of any such
right preclude any other or further exercise thereof or the exercise of any
other right.

               (b) Upon the execution and delivery or authentication by any
Person of a security agreement supplement in substantially the form of Exhibit D
hereto (each a "Security

                                      27
<PAGE>

Agreement Supplement"), (i) such Person shall be referred to as an "Additional
Grantor" and shall be and become a Grantor hereunder and each reference in this
Agreement and the other Loan Documents to "Grantor" shall also mean and be a
reference to such Additional Grantor, and (ii) the supplemental schedules
attached to each Security Agreement Supplement shall be incorporated into and
become a part of and supplement the corresponding Schedules hereto, and the
Collateral Agent may attach such supplemental schedules to such Schedules; and
each reference to such Schedules shall mean and be a reference to such Schedules
as supplemented pursuant to each Security Agreement Supplement.

          Section 25. Notices; Etc. All notices and other communications
                      ------------
provided for hereunder shall be in writing (including telecopier communication)
and mailed, telecopied or delivered to, in the case of the Borrower or the
Parent, addressed to it at its address specified in the Credit Agreement and, in
the case of each Grantor other than the Borrower and the Parent, addressed to it
at its address set forth opposite such Grantor's name on the signature pages
hereto or on the signature page to the Security Agreement Supplement pursuant to
which it became a party hereto; or, as to any party, at such other address as
shall be designated by such party in a written notice to the other parties. All
such notices and other communications shall, when mailed or telecopied, be
effective when deposited in the mails or telecopied, respectively, addressed as
aforesaid, except that notices and other communications to the Collateral Agent
shall not be effective until received by the Collateral Agent. Delivery by
telecopier of an executed counterpart of any amendment or waiver of any
provision of this Agreement or of any Security Agreement Supplement or Schedule
hereto shall be effective as delivery of an original executed counterpart
thereof.

          Section 26. Continuing Security Interest; Assignments under the Credit
                      ----------------------------------------------------------
Agreement, Etc. (a) This Agreement shall create a continuing security interest
--------------
in the Collateral and shall (i) remain in full force and effect until the
payment in full in cash of the Secured Obligations, (ii) be binding upon each
Grantor, its successors and assigns and (iii) inure, together with the rights
and remedies of the Collateral Agent hereunder, to the benefit of the Lenders
and their respective successors, transferees and assigns. Without limiting the
generality of the foregoing clause (iii), any Lender may assign or otherwise
transfer all or any portion of its rights and obligations under the Credit
Agreement (including, without limitation, all or any portion of its Commitments)
to any other Person, and such other Person shall thereupon become vested with
all the benefits in respect thereof granted to such Lender herein or otherwise,
in each case as provided in Section 8.05(b)of the Credit Agreement. None of the
rights or obligations of any Grantor hereunder may be assigned or otherwise
transferred without the prior written consent of the Collateral Agent, and any
such assignment or transfer shall be null and void.

               (b) This Agreement shall continue to be effective or be
automatically reinstated, as the case may be, if at any time payment, in whole
or in part, of any of the Secured Obligations is rescinded or must otherwise be
restored or returned by the Collateral Agent or any Lender as a preference,
fraudulent conveyance or otherwise under any bankruptcy, insolvency or similar
law.

          Section 27. Release; Termination. (a) Upon any sale, lease, transfer
                      --------------------
or other disposition of any item of Collateral of any Grantor in accordance with
the terms of the Loan Documents (other than sales of Inventory in the ordinary
course of business), the Collateral

                                      28
<PAGE>

Agent will, at such Grantor's expense, execute and deliver to such Grantor such
documents as such Grantor shall reasonably request to evidence the release of
such item of Collateral from the assignment and security interest granted
hereby; provided, however, that (i) at the time of such request and such release
        --------  -------
no Default shall have occurred and be continuing, (ii) such Grantor shall have
delivered to the Collateral Agent, at least 10 days prior to the date of the
proposed release, a written request for release describing the item of
Collateral and the terms of the sale, lease, transfer or other disposition in
reasonable detail, including, without limitation, the price thereof and any
expenses in connection therewith, together with a form of release for execution
by the Collateral Agent and a certificate of such Grantor to the effect that the
transaction is in compliance with the Loan Documents and as to such other
matters as the Collateral Agent may request and (iii) the proceeds of any such
sale, lease, transfer or other disposition required to be applied, or any
payment to be made in connection therewith, in accordance with Section 2.04 of
the Credit Agreement shall, to the extent so required, be paid or made to, or in
accordance with the instructions of, the Collateral Agent when and as required
under Section 2.04 of the Credit Agreement.

               (b) Upon the payment in full in cash of the Secured Obligations
(except in respect of indemnification that survives repayment of the
indebtedness), the pledge, assignment and security interest granted hereby shall
terminate and all rights to the Collateral shall revert to the applicable
Grantor. Upon any such termination, the Collateral Agent will, at the applicable
Grantor's expense, execute and deliver to such Grantor such documents as such
Grantor shall reasonably request to evidence such termination.

          Section 28. Execution in Counterparts. This Agreement may be executed
                      -------------------------
in any number of counterparts, each of which when so executed shall be deemed to
be an original and all of which taken together shall constitute one and the same
agreement. Delivery of an executed counterpart of a signature page to this
Agreement by telecopier shall be effective as delivery of an original executed
counterpart of this Agreement.

          Section 29. Governing Law. This Agreement shall be governed by, and
                      -------------
construed in accordance with, the laws of the State of New York.

          Section 30. Waiver of Jury Trial. TO THE EXTENT PERMITTED BY
                      --------------------
APPLICABLE LAW, EACH OF THE PARTIES TO THIS SECURITY AGREEMENT HEREBY
IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR
COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS SECURITY AGREEMENT OR THE
TRANSACTIONS CONTEMPLATED HEREBY.

                                      29

     IN WITNESS  WHEREOF,  each  Grantor  has caused this  Agreement  to be duly
executed and delivered by its officer  thereunto duly  authorized as of the date
