and other property paid over to or received by the Collateral Agent pursuant to
the provisions of this paragraph (b) shall be retained by the Collateral Agent
in an account to be established by the Collateral Agent upon receipt of such
money or other property and shall be applied in accordance with the provisions
of Section 7. After all Events of Default have been cured or waived, the
Collateral Agent shall, within five Business Days after all such Events of
Default have been cured or waived, repay to each Pledgor all cash dividends,
interest or principal (without interest), that such Pledgor would otherwise be
permitted to retain pursuant to the terms of paragraph (a)(iii) above and which
remain in such account.

         (c) Upon the occurrence and during the continuance of an Event of
Default, all rights of any Pledgor to exercise the voting and consensual rights
and powers it is entitled to exercise pursuant to paragraph (a)(i) of this
Section 5, and the obligations of the Collateral Agent under paragraph (a)(ii)
of this Section 5, shall cease, and all such rights shall thereupon become
vested in the Collateral Agent, which shall have the sole and exclusive right
and authority to exercise such voting and consensual rights and powers, provided
that, unless otherwise directed by the Required Lenders, the Collateral Agent
shall have the right from time to time following and during the continuance of
an Event of Default to permit the Pledgors to exercise such rights. After all
Events of Default have been cured or waived, such Pledgor will have the right to
exercise the voting and consensual rights and powers that it would otherwise be
entitled to exercise pursuant to the terms of paragraph (a)(i) above.

         SECTION 6. Remedies upon Default. Upon the occurrence and during the
continuance of an Event of Default, subject to applicable regulatory and legal
requirements, the Collateral Agent may sell the Collateral, or any part thereof,
at public or private sale or at any broker's board or on any securities
exchange, for cash, upon credit or for future delivery as the Collateral Agent
shall deem appropriate; provided that any and all Roberts Collateral, WOW
Collateral and Southwest Collateral must first be applied to repay the Roberts
Obligation, WOW Obligation and Southwest Obligation, respectively, and only
thereafter may be used to repay amounts outstanding under the remainder of the
General Obligations. The Collateral Agent shall be authorized at any such sale
(if it deems it advisable to


                                     Page 11
<PAGE>

do so) to restrict the prospective bidders or purchasers to persons who will
represent and agree that they are purchasing the Collateral for their own
account for investment and not with a view to the distribution or sale thereof,
and upon consummation of any such sale the Collateral Agent shall have the right
to assign, transfer and deliver to the purchaser or purchasers thereof the
Collateral so sold. Each such purchaser at any such sale shall hold the property
sold absolutely free from any claim or right on the part of any Pledgor, and, to
the extent permitted by applicable law, the Pledgors hereby waive all rights of
redemption, stay, valuation and appraisal any Pledgor now has or may at any time
in the future have under any rule of law or statute now existing or hereafter
enacted.

         The Collateral Agent shall give a Pledgor 10 days' prior written notice
(which each Pledgor agrees is reasonable notice within the meaning of Section
9-504(3) of the Uniform Commercial Code as in effect in the State of New York or
its equivalent in other jurisdictions) of the Collateral Agent's intention to
make any sale of such Pledgor's Collateral. Such notice, in the case of a public
sale, shall state the time and place for such sale and, in the case of a sale at
a broker's board or on a securities exchange, shall state the board or exchange
at which such sale is to be made and the day on which the Collateral, or portion
thereof, will first be offered for sale at such board or exchange. Any such
public sale shall be held at such time or times within ordinary business hours
and at such place or places as the Collateral Agent may fix and state in the
notice of such sale. At any such sale, the Collateral, or portion thereof, to be
sold may be sold in one lot as an entirety or in separate parcels, as the
Collateral Agent may (in its sole and absolute discretion) determine. The
Collateral Agent shall not be obligated to make any sale of any Collateral if it
shall determine not to do so, regardless of the fact that notice of sale of such
Collateral shall have been given. The Collateral Agent may, without notice or
publication, adjourn any public or private sale or cause the same to be
adjourned from time to time by announcement at the time and place fixed for
sale, and such sale may, without further notice, be made at the time and place
to which the same was so adjourned. In case any sale of all or any part of the
Collateral is made on credit or for future delivery, the Collateral so sold may
be retained by the Collateral Agent until the sale price is paid in full by the
purchaser or


                                     Page 12
<PAGE>

purchasers thereof, but the Collateral Agent shall not incur any liability in
case any such purchaser or purchasers shall fail to take up and pay for the
Collateral so sold and, in case of any such failure, such Collateral may be sold
again upon like notice. At any public (or, to the extent permitted by applicable
law, private) sale made pursuant to this Section 6, any Secured Party may bid
for or purchase, free from any right of redemption, stay or appraisal on the
part of any Pledgor (all said rights being also hereby waived and released), the
Collateral or any part thereof offered for sale and may make payment on account
thereof by using any claim then due and payable to it from such Pledgor as a
credit against the purchase price, and it may, upon compliance with the terms of
sale, hold, retain and dispose of such property without further accountability
to such Pledgor therefor. For purposes hereof, (a) a written agreement to
purchase the Collateral or any portion thereof shall be treated as a sale
thereof, (b) the Collateral Agent shall be free to carry out such sale pursuant
to such agreement and (c) such Pledgor shall not be entitled to the return of
the Collateral or any portion thereof subject to such agreement, notwithstanding
the fact that after the Collateral Agent shall have entered into such an
agreement all Events of Default shall have been remedied and the Obligations
paid in full. As an alternative to exercising the power of sale herein conferred
upon it, the Collateral Agent may proceed by a suit or suits at law or in equity
to foreclose upon the Collateral and to sell the Collateral or any portion
thereof pursuant to a judgment or decree of a court or courts having competent
jurisdiction or pursuant to a proceeding by a court-appointed receiver. Any sale
pursuant to the provisions of this Section 6 shall be deemed to conform to the
commercially reasonable standards as provided in Section 9-504(3) of the Uniform
Commercial Code as in effect in the State of New York or its equivalent in other
jurisdictions.

         SECTION 7. Application of Proceeds of Sale. (a) The proceeds of
any sale of Collateral pursuant to Section 6, as well as any Collateral
consisting of cash, shall be applied by the Collateral Agent as follows:

                  FIRST, to the payment of all costs and expenses incurred by
         the Collateral Agent in connection with such sale or otherwise in
         connection with this Agreement, any other Loan Document or any


                                     Page 13
<PAGE>

         of the Obligations, including all court costs and the reasonable fees
         and expenses of its agents and legal counsel, the repayment of all
         advances made by the Collateral Agent hereunder or under any other
         Loan Document on behalf of any Pledgor and any other costs or expenses
         incurred in connection with the exercise of any right or remedy
         hereunder or under any other Loan Document;

                  SECOND, to the payment in full of the Obligations (the amounts
         so applied to be distributed among the Secured Parties pro rata in
         accordance with the amounts of the Obligations owed to them on the date
         of any such distribution); and

                  THIRD, to the Pledgors, their successors or assigns, or as a
         court of competent jurisdiction may otherwise direct.

         (b) Notwithstanding any contrary provision of paragraph (a) of this
Section, (i) proceeds of Collateral and cash Collateral other than the Roberts
Collateral, the WOW Collateral and the Southwest Collateral shall not be applied
to the payment of Roberts Obligations, WOW Obligations or Southwest Obligations,
(ii) proceeds of WOW Collateral and cash WOW Collateral shall not be applied to
the payment of Roberts Obligations or Southwest Obligations, and shall be
applied to the payment of WOW Obligations, until the WOW Obligations have been
paid in full, prior to being applied to payment of the General Obligations,
(iii) proceeds of Roberts Collateral and cash Roberts Collateral shall not be
applied to the payment of WOW Obligations or Southwest Obligations, and shall be
applied to the payment of the Roberts Obligations, until the Roberts Obligations
have been paid in full, prior to being applied to payment of the General
Obligations and (iv) proceeds of Southwest Collateral and cash Southwest
Collateral shall not be applied to the payment of Roberts Obligations or WOW
Obligations and shall be applied to payment of Southwest Obligations, until the
Southwest Obligations have been paid in full, prior to being applied to payment
of General Obligations.

         (c) The Collateral Agent shall have absolute discretion as to the time
of application of any such proceeds, moneys or balances in accordance with this
Agreement. Upon any sale of the Collateral by the Collateral Agent (including
pursuant to a power of sale granted by statute or under a judicial proceeding),
the receipt of the purchase money by the Collateral Agent or of the officer
making the sale shall be a sufficient discharge to the purchaser or purchasers
of the Collateral so sold and such purchaser or purchasers shall not be
obligated to see to the application of any part of the purchase money paid over
to the Collateral Agent or such officer or be



                                     Page 14
<PAGE>

answerable in any way for the misapplication thereof.

         SECTION 8. Reimbursement of Collateral Agent. (a) Each Pledgor agrees
to pay upon demand to the Collateral Agent the amount of any and all reasonable
expenses, including the reasonable fees, other charges and disbursements of its
counsel and of any experts or agents, that the Collateral Agent may incur in
connection with (i) the administration of this Agreement, (ii) the custody or
preservation of, or the sale of, collection from, or other realization upon, any
of the Collateral, (iii) the exercise or enforcement of any of the rights of the
Collateral Agent hereunder or (iv) the failure by such Pledgor to perform or
observe any of the provisions hereof.

         (b) Without limitation of its indemnification obligations under the
other Loan Documents, each Pledgor agrees to indemnify the Collateral Agent and
the Indemnitees (as defined in Section 9.03 of the Credit Agreement) against,
and hold each Indemnitee harmless from, any and all losses, claims, damages,
liabilities and related expenses, including reasonable counsel fees, other
charges and disbursements, incurred by or asserted against any Indemnitee
arising out of, in any way connected with, or as a result of (i) the execution
or delivery of this Agreement or any other Loan Document or any agreement or
instrument contemplated hereby or thereby, the performance by the parties hereto
of their respective obligations thereunder or the consummation of the
Transactions and the other transactions contemplated thereby or (ii) any claim,
litigation, investigation or proceeding relating to any of the foregoing,
whether or not any Indemnitee is a party thereto, provided that such indemnity
shall not, as to any Indemnitee, be available to the extent that such losses,
claims, damages, liabilities or related expenses are determined by a court of
competent jurisdiction by final and nonappealable judgment to have resulted from
the gross negligence or wilful misconduct of such Indemnitee.

         (c) Any amounts payable as provided hereunder shall be additional
Obligations secured hereby and by the other Security Documents. The provisions
of this Section 8 shall remain operative and in full force and effect regardless
of the termination of this Agreement, the consummation of the transactions
contemplated hereby, the repayment of any of the Obligations, the invalidity or
unenforceability of any term or provision of this Agreement or any other Loan
Document or any investigation made by or on behalf of the Collateral Agent or
any other Secured Party. All amounts due under this Section 8 shall be payable
on written demand therefor and shall bear interest at the rate specified in
Section 2.12 of the Credit Agreement.

         SECTION 9. Collateral Agent Appointed Attorney-in-Fact. Each Pledgor
hereby appoints the Collateral Agent the attorney-in-fact of such


                                     Page 15
<PAGE>

Pledgor for the purpose of carrying out the provisions of this Agreement and
taking any action and executing any instrument that the Collateral Agent may
deem necessary or advisable to accomplish the purposes hereof, which appointment
is irrevocable and coupled with an interest. Without limiting the generality of
the foregoing, the Collateral Agent shall have the right, upon the occurrence
and during the continuance of an Event of Default, with full power of
substitution either in the Collateral Agent's name or in the name of such
Pledgor, to ask for, demand, sue for, collect, receive and give acquittance for
any and all moneys due or to become due under and by virtue of any Collateral,
to endorse checks, drafts, orders and other instruments for the payment of money
payable to the Pledgor representing any interest or dividend or other
distribution payable in respect of the Collateral or any part thereof or on
account thereof and to give full discharge for the same, to settle, compromise,
prosecute or defend any action, claim or proceeding with respect thereto, and to
sell, assign, endorse, pledge, transfer and to make any agreement respecting, or
otherwise deal with, the same; provided, however, that nothing herein contained
shall be construed as requiring or obligating the Collateral Agent to make any
commitment or to make any inquiry as to the nature or sufficiency of any payment
received by the Collateral Agent, or to present or file any claim or notice, or
to take any action with respect to the Collateral or any part thereof or the
moneys due or to become due in respect thereof or any property covered thereby.
The Collateral Agent and the other Secured Parties shall be accountable only for
amounts actually received as a result of the exercise of the powers granted to
them herein, and neither they nor their officers, directors, employees or agents
shall be responsible to any Pledgor for any act or failure to act hereunder,
except for their own gross negligence or wilful misconduct.

         SECTION 10. Waivers; Amendment. (a) No failure or delay of the
Collateral Agent in exercising any power or right hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise of any such right or
power, or any abandonment or discontinuance of steps to enforce such a right or
power, preclude any other or further exercise thereof or the exercise of any
other right or power. The rights and remedies of the Collateral Agent hereunder
and of the other Secured Parties under the other Loan Documents are cumulative
and are not exclusive of any rights or remedies that they would otherwise have.
No waiver of any provisions of this Agreement or consent to any departure by any
Pledgor therefrom shall in any event be effective unless the same shall be
permitted by paragraph (b) below, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given. No
notice or demand on any Pledgor in any case shall entitle such Pledgor to any
other or further notice or demand in similar or other circumstances.


                                     Page 16
<PAGE>

         (b) Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to a written agreement entered into between
the Collateral Agent and the Pledgor or Pledgors with respect to which such
waiver, amendment or modification is to apply, subject to any consent required
in accordance with Section 9.02 of the Credit Agreement.

         SECTION 11. Securities Act, etc. In view of the position of the
Pledgors in relation to the Pledged Securities, or because of other current or
future circumstances, a question may arise under the Securities Act of 1933, as
now or hereafter in effect, or any similar statute hereafter enacted analogous
in purpose or effect (such Act and any such similar statute as from time to time
in effect being called the "Federal Securities Laws") with respect to any
disposition of the Pledged Securities permitted hereunder. Each Pledgor
understands that compliance with the Federal Securities Laws might very strictly
limit the course of conduct of the Collateral Agent if the Collateral Agent were
to attempt to dispose of all or any part of the Pledged Securities, and might
also limit the extent to which or the manner in which any subsequent transferee
of any Pledged Securities could dispose of the same. Similarly, there may be
other legal restrictions or limitations affecting the Collateral Agent in any
attempt to dispose of all or part of the Pledged Securities under applicable
Blue Sky or other state securities laws or similar laws analogous in purpose or
effect. Each Pledgor recognizes that in light of such restrictions and
limitations the Collateral Agent may, with respect to any sale of the Pledged
Securities, limit the purchasers to those who will agree, among other things, to
acquire such Pledged Securities for their own account, for investment, and not
with a view to the distribution or resale thereof. Each Pledgor acknowledges and
agrees that in light of such restrictions and limitations, the Collateral Agent,
in its sole and absolute discretion, (a) may proceed to make such a sale whether
or not a registration statement for the purpose of registering such Pledged
Securities or part thereof shall have been filed under the Federal Securities
Laws and (b) may approach and negotiate with a single potential purchaser to
effect such sale. Each Pledgor acknowledges and agrees that any such sale might
result in prices and other terms less favorable to the seller than if such sale
were a public sale without such restrictions. In the event of any such sale, the
Collateral Agent shall incur no responsibility or liability for selling all or
any part of the Pledged Securities at a price that the Collateral Agent, in its
sole and absolute discretion, may in good faith deem reasonable


                                     Page 17
<PAGE>

under the circumstances, notwithstanding the possibility that a substantially
higher price might have been realized if the sale were deferred until after
registration as aforesaid or if more than a single purchaser were approached.
The provisions of this Section 11 will apply notwithstanding the existence of a
public or private market upon which the quotations or sales prices may exceed
substantially the price at which the Collateral Agent sells.

         SECTION 12. Registration, etc. Each Pledgor agrees that, upon the
occurrence and during the continuance of an Event of Default hereunder, if for
any reason the Collateral Agent desires to sell any of the Pledged Securities of
the Borrower at a public sale, it will, at any time and from time to time, upon
the written request of the Collateral Agent, use its best efforts to take or to
cause the issuer of such Pledged Securities to take such action and prepare,
distribute and/or file such documents, as are required or advisable in the
reasonable opinion of counsel for the Collateral Agent to permit the public sale
of such Pledged Securities. Each Pledgor further agrees to indemnify, defend and
hold harmless the Collateral Agent, each other Secured Party, any underwriter
and their respective officers, directors, affiliates and controlling persons
from and against all loss, liability, expenses, costs of counsel (including,
without limitation, reasonable fees and expenses to the Collateral Agent of
legal counsel), and claims (including the costs of investigation) that they may
incur insofar as such loss, liability, expense or claim arises out of or is
based upon any alleged untrue statement of a material fact contained in any
prospectus (or any amendment or supplement thereto) or in any notification or
offering circular, or arises out of or is based upon any alleged omission to
state a material fact required to be stated therein or necessary to make the
statements in any thereof not misleading, except insofar as the same may have
been caused by any untrue statement or omission based upon information furnished
in writing to such Pledgor or the issuer of such Pledged Securities by the
Collateral Agent or any other Secured Party expressly for use therein. Each
Pledgor further agrees, upon such written request referred to above, to use its
best efforts to qualify, file or register, or cause the issuer of such Pledged
Securities to qualify, file or register, any of the Pledged Securities under the
Blue Sky or other securities laws of such states as may be requested by the
Collateral Agent and keep effective, or cause to be kept effective, all such
qualifications, filings or registrations. Each Pledgor will bear all costs and
expenses of carrying out its obligations under this Section 12.


                                     Page 18
<PAGE>

Each Pledgor acknowledges that there is no adequate remedy at law for failure by
it to comply with the provisions of this Section 12 and that such failure would
not be adequately compensable in damages, and therefore agrees that its
agreements contained in this Section 12 may be specifically enforced.

         SECTION 13. Security Interest Absolute. All rights of the Collateral
Agent hereunder, the grant of a security interest in the Collateral and all
obligations of each Pledgor hereunder, shall be absolute and unconditional
irrespective of (a) any lack of validity or enforceability of the Credit
Agreement, any other Loan Document, any agreement with respect to any of the
Obligations or any other agreement or instrument relating to any of the
foregoing, (b) any change in the time, manner or place of payment of, or in any
other term of, all or any of the Obligations, or any other amendment or waiver
of or any consent to any departure from the Credit Agreement, any other Loan
Document or any other agreement or instrument relating to any of the foregoing,
(c) any exchange, release or nonperfection of any other collateral, or any
release or amendment or waiver of or consent to or departure from any guaranty,
for all or any of the Obligations or (d) any other circumstance that might
otherwise constitute a defense available to, or a discharge of, any Pledgor in
respect of the Obligations or in respect of this Agreement (other than the
indefeasible payment in full of all the Obligations).

         SECTION 14. Termination or Release. (a) This Agreement and the security
interests granted hereby shall terminate when all the Obligations have been
indefeasibly paid in full and the Lenders have no further commitment to lend
under the Credit Agreement, the LC Exposure has been reduced to zero and the
Issuing Bank has no further obligation to issue Letters of Credit under the
Credit Agreement.

         (b) Upon any sale or other transfer by any Pledgor of any Collateral
that is permitted under the Credit Agreement to any person that is not a
Pledgor, or, upon the effectiveness of any written consent to the release of the
security interest granted hereby in any Collateral pursuant to the Credit
Agreement, the security interest in such Collateral shall be automatically
released.

         (c) In connection with any termination or release pursuant to paragraph
(a) or (b), the Collateral Agent shall execute and deliver to any Pledgor, at
such Pledgor's expense, all documents that such Pledgor shall reasonably request
to evidence such termination or release. Any execution and delivery of documents
pursuant to this Section 14 shall be without recourse to or warranty by the
Collateral Agent.


                                     Page 19
<PAGE>

         SECTION 15. Notices. All communications and notices hereunder
shall be in writing and given as provided in Section 9.01 of the Credit
Agreement. All communications and notices hereunder to any Subsidiary
Pledgor shall be given to it in care of the Borrower.

         SECTION 16. Further Assurances. Each Pledgor agrees to do such further
acts and things, and to execute and deliver such additional conveyances,
assignments, agreements and instruments, as the Collateral Agent may at any time
reasonably request in connection with the administration and enforcement of this
Agreement or with respect to the Collateral or any part thereof or in order
better to assure and confirm unto the Collateral Agent its rights and remedies
hereunder.

         SECTION 17. Binding Effect; Several Agreement; Assignments. Whenever in
this Agreement any of the parties hereto is referred to, such reference shall be
deemed to include the successors and assigns of such party; and all covenants,
promises and agreements by or on behalf of any Pledgor that are contained in
this Agreement shall bind and inure to the benefit of its successors and
assigns. This Agreement shall become effective as to any Pledgor when a
counterpart hereof executed on behalf of such Pledgor shall have been delivered
to the Collateral Agent and a counterpart hereof shall have been executed on
behalf of the Collateral Agent, and thereafter shall be binding upon such
Pledgor and the Collateral Agent and their respective successors and assigns,
and shall inure to the benefit of such Pledgor, the Collateral Agent and the
other Secured Parties, and their respective successors and assigns, except that
no Pledgor shall have the right to assign its rights hereunder or any interest
herein or in the Collateral (and any such attempted assignment shall be void),
except as expressly contemplated by this Agreement or the other Loan Documents.
If all of the capital stock of a Pledgor is sold, transferred or otherwise
disposed of to a person that is not an Affiliate of the Borrower pursuant to a
transaction permitted by Section 6.05 of the Credit Agreement, such Pledgor
shall be released from its obligations under this Agreement without further
action. This Agreement shall be construed as a separate agreement with respect
to each Pledgor and may be amended, modified, supplemented, waived or released
with respect to any Pledgor without the approval of any other Pledgor and
without affecting the obligations of any other Pledgor hereunder

         SECTION 18. Survival of Agreement; Severability. (a) All covenants,
agreements, representations and warranties made by each Pledgor herein and in
the certificates or other instruments prepared or delivered in connection with
or pursuant to this Agreement or any other Loan Document shall be considered to
have been relied upon by the Collateral Agent and the other Secured Parties and
shall survive the making by the Lenders of the Loans and the issuance of the
Letters of Credit by the Issuing Bank, regardless of any investigation made by
the Secured Parties or on their behalf, and shall continue in full force and
effect as long as the



                                     Page 20
<PAGE>

principal of or any accrued interest on any Loan or any other fee or amount
payable under this Agreement or any other Loan Document is outstanding and
unpaid or the LC Exposure does not equal zero and as long as the Commitments and
the LC Commitments have not been terminated.

         (b) In the event any one or more of the provisions contained in this
Agreement should be held invalid, illegal or unenforceable in any respect, the
validity, legality and enforceability of the remaining provisions contained
herein shall not in any way be affected or impaired thereby (it being understood
that the invalidity of a particular provision in a particular jurisdiction shall
not in and of itself affect the validity of such provision in any other
jurisdiction). The parties shall endeavor in good-faith negotiations to replace
the invalid, illegal or unenforceable provisions with valid provisions the
economic effect of which comes as close as possible to that of the invalid,
illegal or unenforceable provisions.

         SECTION 19. Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY,
AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

         SECTION 20. Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall constitute an original, but all of which, when
taken together, shall constitute a single contract, and shall become effective
as provided in Section 17. Delivery of an executed counterpart of a signature
page to this Agreement by facsimile transmission shall be as effective as
delivery of a manually executed counterpart of this Agreement.

         SECTION 21. Rules of Interpretation. The rules of interpretation
specified in Section 1.03 of the Credit Agreement shall be applicable to this
Agreement. Section headings used herein are for convenience of reference only,
are not part of this Agreement and are not to affect the construction of, or to
be taken into consideration in interpreting this Agreement.

         SECTION 22. Jurisdiction; Consent to Service of Process. (a) Each
Pledgor hereby irrevocably and unconditionally submits, for itself and its
property, to the nonexclusive jurisdiction of any New York State court or
Federal court of the United States of America sitting in New York City, and any
appellate court from any thereof, in any action or proceeding arising out of or
relating to this Agreement or the other Loan Documents, or for recognition or
enforcement of any judgment, and each of the parties hereto hereby irrevocably
and unconditionally agrees that, to the extent permitted by applicable law, all
claims in respect of any such action or


                                     Page 21
<PAGE>

proceeding may be heard and determined in such New York State or, to the extent
permitted by law, in such Federal court. Each of the parties hereto agrees that
a final judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law. Nothing in this Agreement shall affect any right that the
Collateral Agent or any other Secured Party may otherwise have to bring any
action or proceeding relating to this Agreement or the other Loan Documents
against any Pledgor or its properties in the courts of any jurisdiction.

         (b) Each Pledgor hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection that it may
now or hereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Agreement or the other Loan Documents in any
New York State or Federal court. Each of the parties hereto hereby irrevocably
waives, to the fullest extent permitted by law, the defense of an inconvenient
forum to the maintenance of such action or proceeding in any such court.

         (c) Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 15. Nothing in this
Agreement will affect the right of any party to this Agreement to serve process
in any other manner permitted by law.

         SECTION 23. Waiver Of Jury Trial. EACH PARTY HERETO HEREBY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL
BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF,
UNDER OR IN CONNECTION WITH THIS AGREEMENT. EACH PARTY HERETO (A) CERTIFIES THAT
NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF
LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT
AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY,
AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

         SECTION 24. Additional Pledgors. Pursuant to Section 5.12 of the Credit
Agreement, certain Subsidiaries of the Borrower that were not in existence or
not a Subsidiary on the date of the Credit Agreement are required to enter in
this Agreement as a Subsidiary Pledgor upon becoming a Subsidiary if such
Subsidiary owns or possesses property of a type that would be considered
Collateral hereunder. Upon execution and delivery by the Collateral Agent and a
Subsidiary of an instrument in the form of Annex


                                     Page 22
<PAGE>

1, such Subsidiary shall become a Subsidiary Pledgor hereunder with the same
force and effect as if originally named as a Subsidiary Pledgor herein. The
execution and delivery of such instrument shall not require the consent of any
Pledgor hereunder. The rights and obligations of each Pledgor hereunder shall
remain in full force and effect notwithstanding the addition of any new
Subsidiary Pledgor as a party to this Agreement.

         SECTION 25. Execution of Financing Statements. Pursuant to Section
9-402 of the Uniform Commercial Code as in effect in the State of New York or
its equivalent in other jurisdictions, each Pledgor authorizes the Collateral
Agent to file financing statements with respect to the Collateral owned by it
without the signature of such Pledgor in such form and in such filing offices as
the Collateral Agent reasonably determines appropriate to perfect the security
interests of the Collateral Agent under this Agreement. A carbon, photographic
or other reproduction of this Agreement shall be sufficient as a financing
statement for filing in any jurisdiction.

         SECTION 26. Compliance with Laws. Notwithstanding anything herein which
may be construed to the contrary, no action shall be taken by any of the
Collateral Agent and the Secured Parties with respect to the Pledged Securities
(including termination or suspension of voting rights) unless and until any
required approval under the Federal Communications Act of 1934, and any
applicable rules and regulations thereunder, requiring the consent to or
approval of such action by the FCC or any governmental or other authority, have
been satisfied, and, to the extent applicable, any remedial action taken with
respect to the Collateral shall be subject to other applicable laws.

         IN WITNESS WHEREOF, the parties hereto have duly executed this
Agreement as of the day and year first above written.

         A. Reference is made to (a) the Amended and Restated Credit Agreement

         C. The Pledgors have entered into the Pledge Agreement in order to
induce the Lenders to make Loans and the Issuing Bank to issue Letters of
Credit. Pursuant to Section 5.12 of the Credit Agreement, certain Subsidiaries
of the Borrower that were not in existence or not a Subsidiary on the date of
the Credit Agreement are required to enter into the Pledge Agreement as a
Subsidiary Pledgor upon becoming a Subsidiary if such Subsidiary owns or
possesses property of a type that would be considered Collateral under the
Pledge Agreement. Section 24 of the Pledge Agreement provides that such
Subsidiaries may become Subsidiary Pledgors under the Pledge Agreement by
execution and delivery of an instrument in the form of this Supplement. The
undersigned Subsidiary (the "New Pledgor") is executing this Supplement in
accordance with the requirements of the Credit Agreement to become a Subsidiary
Pledgor under the Pledge Agreement in order to induce the Lenders to make
additional Loans and the Issuing Bank to issue additional Letters of Credit and
as consideration for Loans previously made and Letters of Credit previously
issued.

         Accordingly, the Collateral Agent and the New Pledgor agree as follows:

         SECTION 1. In accordance with Section 24 of the Pledge Agreement, the
New Pledgor by its signature below becomes a Pledgor under the Pledge Agreement
with the same force and effect as if originally named therein as a Pledgor and
the New Pledgor hereby agrees (a) to all the terms and provisions of the Pledge
Agreement applicable to it as a Pledgor thereunder and (b) represents and
warrants that the representations and warranties made by it as a Pledgor
thereunder are true and correct on and as of the date hereof. In furtherance of
the foregoing, the New Pledgor, as security for the payment and performance in
full of the Obligations (as defined in the Pledge Agreement and subject to the
second proviso of Section 1 of the Pledge Agreement), does hereby create and
grant to the Collateral Agent, its successors and assigns, for the benefit of
the Secured Parties, their successors and assigns, a security interest in and
lien on all of the New Pledgor's right, title and interest in and to the
Collateral (as defined in the Pledge Agreement) of the New Pledgor. Each
reference to a "Subsidiary Pledgor" or a "Pledgor" in the Pledge Agreement shall
be deemed to include the New Pledgor. The Pledge Agreement is hereby
incorporated herein by reference.

         SECTION 2. The New Pledgor represents and warrants to the Collateral
Agent and the other Secured Parties that this Supplement has been duly
authorized, executed and delivered by it and constitutes its legal, valid and
binding obligation, enforceable against it in accordance with its terms ,
subject to applicable bankruptcy, insolvency, reorganization, moratorium or
other laws affecting creditors' rights generally and subject to general
principles of equity, regardless of whether considered in a proceeding in equity
or at law.

         SECTION 3. This Supplement may be executed in counterparts, each of
which shall constitute an original, but all of which when taken together shall
constitute a single contract. This Supplement shall become effective when the
Collateral Agent shall have received counterparts of this Supplement that, when
taken together, bear the signatures of the New Pledgor and the Collateral Agent.
Delivery of an executed signature page to this Supplement by facsimile
transmission shall be as effective as delivery of a manually signed counterpart
of this Supplement.

         SECTION 4. The New Pledgor hereby represents and warrants that set
forth on Schedule I attached hereto is a true and correct schedule of all its
Pledged Securities as of the date hereof.

         SECTION 5. Except as expressly supplemented hereby, the Pledge
Agreement shall remain in full force and effect.

         SECTION 6. THIS SUPPLEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

         SECTION 7. In case any one or more of the provisions contained in this
Supplement should be held invalid, illegal or unenforceable in any respect,
neither party hereto shall be required to comply with such provision for so long
as such provision is held to be invalid, illegal or unenforceable, but the
validity, legality and enforceability of the remaining provisions contained
herein and in the Pledge Agreement shall not in any way be affected or impaired.
The parties hereto shall endeavor in good-faith negotiations to replace the
invalid, illegal or unenforceable provisions with valid provisions the economic
effect of which comes as close as possible to that of the invalid, illegal or
unenforceable provisions.

         SECTION 8. All communications and notices hereunder shall be in writing
and given as provided in Section 15 of the Pledge Agreement. All communications
and notices hereunder to the New Pledgor shall be given to it in care of the
Borrower.

         SECTION 9. The New Pledgor agrees to reimburse the Collateral Agent for
its reasonable out-of-pocket expenses in connection with this Supplement,
including the reasonable fees, other charges and

executed this Supplement to the Pledge Agreement as of the day and year first
above written.
