         TO HAVE AND TO HOLD  UNTO the  Collateral  Agent,  for the  benefit  of
itself and on behalf of the Agents and the Lenders, their successors and assigns
forever, upon and subject to the following terms and conditions:

         1. For purposes of this Agreement,  capitalized terms used herein,  and
not otherwise  defined herein,  shall have the meanings  ascribed thereto in the
Loan Agreement.

         2. VCOC hereby  authorizes the Collateral  Agent to file such financing
statements and such other  documents as the Collateral  Agent may deem necessary
or desirable to protect or perfect the interest of the Lenders and the Agents in
the Collateral,  and VCOC further  irrevocably  appoints the Collateral Agent as
VCOC's  attorney-in-fact,  with a power of attorney to execute on behalf of VCOC
such UCC financing statement forms as the Collateral Agent may from time to time
deem  reasonably  necessary or desirable to protect or perfect such  interest in
the Collateral.  Such power of attorney is coupled with an interest and shall be
irrevocable.  In addition, VCOC agrees to make, execute,  deliver or cause to be
done, executed and delivered all such further acts,  documents and things as the
Collateral  Agent may  reasonably  require  for the  purpose  of  perfecting  or
protecting  the rights of the  Lenders  and the Agents  hereunder  or  otherwise
giving effect to this Agreement, all promptly upon request therefor.

         3.       VCOC represents and warrants to the Lenders and the
Agents that:

                  (a) the execution of this Agreement and the fulfillment of the
         terms  hereof  will  not  result  in a  breach  of any of the  terms or
         provisions  of, or  constitute  a default  under,  VCOC's  Articles  of
         Incorporation or By-Laws as presently in effect,  or any order, rule or
         regulation  applicable  to VCOC of any court or of any Federal or state
         regulatory body or  administrative  agency or other  governmental  body
         having  jurisdiction  over  VCOC,  or  result  in  the  termination  or
         cancellation or breach of any inden ture, mortgage, deed of trust, deed
         to secure debt, lease or other agreement or instrument to which VCOC is
         party or by which it is bound or affected;

                                       4


                  (b) VCOC has taken all necessary corporate action to authorize
         the execution and delivery of this Agreement, and this Agreement,  when
         executed and  delivered,  will be the valid and binding  obligation  of
         VCOC  enforceable  in  accordance  with its terms,  subject only to the
         following qualifications:

                       (i) certain equitable remedies are discretionary  and, in
                  particular, may not be available where damages are considered 
                  an adequate remedy at law,

                      (ii) enforcement may be limited by bankruptcy, insolvency,
                  liquidation, reorganization,  reconstruction and other similar
                  laws  affecting  enforcement  of creditors'  rights  generally
                  (insofar as any such law relates to the bankruptcy, insolvency
                  or similar event of VCOC), and

                     (iii) enforcement as to the Licenses is limited by
                  FCC rules and regulations restricting the transfer of
                  the Licenses;

                  (c) Exhibit A attached hereto and incorporated  herein by this
         reference  sets forth a complete and accurate  list of the Contracts in
         effect on the date hereof which provide for aggregate payments over the
         life of each such Contract in excess of $250,000 or which are otherwise
         material to VCOC,  and VCOC will furnish  copies thereof to the Lenders
         and the Agents upon the request of the Collateral Agent; and

                  (d) Exhibit B attached hereto and incorporated  herein by this
         reference  sets  forth a  complete  and  accurate  list  of all  Leases
         providing for  aggregate  payments over the life of any single Lease in
         excess  of  $100,000,  to which  VCOC is party  in  effect  on the date
         hereof,  and VCOC will  furnish  copies  thereof to the Lenders and the
         Agents upon the request of the Collateral Agent.

         4. VCOC further  represents and warrants that the Security  Interest in
the  Collateral  granted  hereunder  shall  constitute  at all times a valid and
perfected first priority  security  interest  (subject only to Permitted Liens),
vested in the  Collateral  Agent in and upon the  Collateral,  free of any Liens
except for Permitted  Liens.  VCOC shall take or cause to be taken such acts and
actions  as shall be  necessary  or  appropriate  to  assure  that the  Security
Interest  in the  Collateral  shall  not  become  subordinate  or  junior to the
security interests, liens or claims of any other Person, and that the Collateral
shall not  otherwise  be or become  subject to any Lien,  except  for  Permitted
Liens.

                                       5


         5. VCOC further  represents  and warrants  that it now keeps all of its
records  concerning  its  Accounts,   Contracts,  Leases,  Other  Contracts  and
Intangibles at its chief executive  office,  which is the address set forth with
respect to VCOC in Section 11.1 of the Loan Agreement. VCOC covenants and agrees
that it shall not keep any of such records at any other address,  unless written
notice thereof is given to the Collateral  Agent at least thirty (30) days prior
to the creation of any new address for the keeping of such records. VCOC further
agrees that it shall  promptly  advise the Collateral  Agent,  in writing making
reference  to this Section 5 of this  Agreement,  of the opening of any material
new place of business the closing of any existing material place of business, or
any change in the location of the place where it keeps the Collateral.

         6. The parties intend that, to the extent  permitted by Applicable Law,
the Collateral shall remain personal property  irrespective of the manner of its
attachment or affixation to realty.

         7. Any and all injury  to, or loss or  destruction  of, the  Collateral
shall be at  VCOC's  risk,  and  shall not  release  VCOC  from its  obligations
hereunder.  VCOC agrees not to sell,  transfer,  assign,  dispose of,  mortgage,
grant a  security  interest  in or  encumber  any of the  Collateral  except  as
permitted  under the Loan  Agreement.  VCOC  agrees to  maintain  in force  such
insurance  with  respect  to  the  Collateral  as is  required  under  the  Loan
Agreement. VCOC agrees to pay all required taxes, liens and assessments upon the
Collateral,  its use or operation,  as required under the Loan  Agreement.  VCOC
further agrees that the Collateral Agent may, but shall in no event be obligated
to, insure any of the Collateral in such form and amount as the Collateral Agent
may deem necessary or desirable if VCOC fails to obtain insurance as required by
the Loan Agreement, and that the Collateral Agent may pay or discharge any taxes
or Liens  (which are not  Permitted  Liens) on any of the  Collateral,  and VCOC
agrees to pay any such sum so expended by the Collateral Agent, with interest at
the  Default  Rate,  and  such  interest  shall  be  deemed  to be a part of the
Obligations secured by the Collateral under the terms of this Agreement.

         8. VCOC shall (i) fulfill,  perform and observe each and every material
condition and covenant contained in any of the Contracts, the Other Contracts or
the Leases,  (ii) give  prompt  notice to the  Collateral  Agent of any claim of
default  under any Contract,  Other  Contract or Lease given to VCOC or by VCOC,
(iii) at the  sole  cost  and  expense  of VCOC,  enforce  the  performance  and
observance of each and every  material  covenant and condition of the Contracts,
the Other  Contracts  and the  Leases  and (iv)  appear in and defend any action
growing out of or in any manner connected with any Contract,  Other Contract or 
Lease.  The rights

                                       6


and interests  granted to the Collateral  Agent hereunder  include all of VCOC's
rights  and title (i) to  modify  the  Contracts,  the Other  Contracts  and the
Leases, (ii) to terminate the Contracts,  the Other Contracts and the Leases and
(iii) to waive or release the  performance  or observance  of any  obligation or
condition  of the  Contracts,  the Other  Contracts  and the  Leases;  provided,
however,  that VCOC shall have the right to exercise  these  rights in a fashion
consistent  with this Agreement and the Loan Agreement  prior to any Default (as
defined  below),  and that these rights shall not be exercised by the Collateral
Agent prior to a Default (as defined below).

         9. Upon the  occurrence  and  during  the  continuation  of an Event of
Default (hereinafter,  a "Default"),  the Lenders and the Agents shall have such
rights and remedies as are set forth in the Loan  Agreement and herein;  all the
rights,  powers and  privileges of a secured party under the Uniform  Commercial
Code of the State of New York and any  other  applicable  jurisdiction;  and all
other  rights and remedies  available  to the Lenders and the Agents,  or any of
them, at law or in equity, including,  without limitation,  the right to sell or
dispose of the Collateral in accordance  with Applicable Law. VCOC covenants and
agrees that any notification of intended disposition of any Collateral,  if such
notice is required by law,  shall be deemed  reasonably  and  properly  given if
given in the manner  provided  for in paragraph 19 hereof at least ten (10) days
prior to such  disposition.  The  Collateral  Agent  shall have the right to the
appointment of a receiver for the properties and assets of VCOC, and VCOC hereby
consents to such rights and to such  appointment and hereby waives any objection
VCOC  may have  thereto  and  hereby  waives  the  right to have a bond or other
security  posted  by the  Collateral  Agent or any other  Person  in  connection
therewith.  VCOC agrees,  after the occurrence of a Default, to take any actions
that the  Collateral  Agent  may  reasonably  request  in order  to  enable  the
Collateral Agent to obtain and enjoy the full rights and benefits granted to the
Collateral  Agent under this  Agreement  and the other Loan  Documents.  Without
limiting  the  generality  of the  foregoing,  VCOC  shall,  at VCOC's  cost and
expense, use its best efforts to assist in obtaining all approvals of the FCC or
the State of New York Public Service Commission,  as applicable,  which are then
required by law for or in connection with any action or transaction contemplated
by this  Agreement or Article 9 of the Uniform  Commercial  Code as in effect in
any applicable  jurisdiction,  and, at the Collateral Agent's request,  prepare,
sign and file with the FCC or the State of New York Public  Service  Commission,
as applicable,  the  assignor's or  transferor's  portion of any  application or
applications  for  consent to the  assignment  of the  Licenses  or  transfer of
control  thereof  necessary or  appropriate  under the FCC's or the State of New
York Public Service Commission's, as applicable, rules for approval of any sale 
or transfer or of the 

                                       7


Collateral Agent's remedies under this Agreement.  The Collateral
Agent shall have the right, in connection with the issuance of
any order for relief in a bankruptcy proceeding to petition the
bankruptcy court for the transfer of control or assignment of the
Licenses to a receiver, trustee, transferee, or similar official
or to any purchaser of the Collateral pursuant to any public or
private sale, foreclosure or other exercise of remedies available
to the Collateral Agent, all as permitted by Applicable Law.  All
amounts realized or collected through the exercise of remedies
hereunder shall be applied as provided in the Loan Agreement.

         10.  Upon the  occurrence  of a Default,  the  Collateral  Agent or its
designee,  may  proceed  to  perform  any  and  all of the  obligations  of VCOC
contained in any of the  Contracts,  Other  Contracts or Leases and exercise any
and all rights of VCOC  therein  contained as fully as VCOC itself  could.  VCOC
hereby  appoints  the  Collateral  Agent  its  attorney-in-fact,  with  power of
substitution,  to take such  action,  execute such  documents,  and perform such
work, as the Collateral Agent may deem appropriate in exercise of the rights and
remedies  granted the Lenders and the Agents,  or any of them,  herein or in any
other Loan Document. The powers herein granted shall include, but not be limited
to, powers to: (i) sue on the Contracts, the Other Contracts or the Leases; (ii)
seek all  governmental  approvals  (other than FCC  approvals)  required for the
operation of the business of VCOC; (iii) modify or terminate the Contracts,  the
Other  Contracts and the Leases;  and (iv) waive or release the  performance  or
observance of any  obligation  under any of the  Contracts,  Other  Contracts or
Leases.  The power of attorney  granted  herein is coupled  with an interest and
shall be irrevocable.

         11. Upon the  occurrence  of a Default,  should VCOC fail to perform or
observe  any  covenant  or comply  with any  condition  contained  in any of the
Contracts, the Other Contracts or the Leases, then the Collateral Agent may, but
without obligation to do so and without releasing VCOC from its obligation to do
so,  perform such covenant or condition  and, to the extent that the  Collateral
Agent  shall  incur  any  costs or pay any  expenses  in  connection  therewith,
including any reasonable costs or expenses of litigation  associated  therewith,
such costs,  expenses or payments shall be included in the  Obligations  secured
hereby and shall bear interest from the payment of such costs or expenses by the
Collateral Agent at the Default Rate. None of the Lenders or the Agents shall be
obliged  to  perform  or  discharge  any  obligation  of VCOC  under  any of the
Contracts, the Other Contracts or the Leases, and, except as may result from the
gross negligence or willful misconduct of the Person seeking  indemnification as
determined by a final order of a court of competent jurisdiction, VCOC agrees to
indemnify and hold harmless each Lender and each Agent against any and all
liability,  loss or damage  which  any such  Person  may incur  under 

                                       8


any of the Contracts, the Other Contracts or the Leases or under or by reason of
this  Agreement,  and any and all claims  and  demands  whatsoever  which may be
asserted  against  VCOC by reason of an act of any Lender or any Agent under any
of the terms of this  Agreement or under the Contracts,  the Other  Contracts or
the Leases.

         12.  VCOC  hereby  further   appoints  the  Collateral   Agent  as  its
attorney-in-fact,  with power of  substitution,  with  authority  to collect all
Accounts,  to endorse the name of VCOC on any note,  acceptance,  check,  draft,
money order or other evidence of debt or of payment which  constitutes a portion
of the  Collateral and which may come into the possession of the Lenders and the
Agents,  or any of them,  and  generally to do such other things and acts in the
name of VCOC with respect to the  Collateral as are necessary or  appropriate to
protect or enforce the rights  hereunder  of the  Lenders  and the Agents.  VCOC
further  authorizes  the  Collateral  Agent,  effective upon the occurrence of a
Default,  to  compromise  and settle or to sell,  assign or  transfer or to ask,
collect,  receive or issue any and all claims possessed by VCOC which constitute
a  portion  of the  Collateral,  all in the name of VCOC.  After  deducting  all
reasonable  expenses and charges  (including the Collateral  Agent's  attorneys'
fees) of retaking,  keeping, storing and selling the Collateral,  the Collateral
Agent may apply the proceeds in payment of any of the  Obligations  in the order
of application  set forth in the Loan Agreement.  The power of attorney  granted
herein is coupled with an interest and shall be irrevocable. VCOC agrees that if
steps are taken by the Collateral Agent to enforce its rights  hereunder,  or to
realize upon any of the Collateral,  VCOC shall pay to the Collateral  Agent the
amount of the Collateral  Agent's costs,  including  attorneys' fees, and VCOC's
obligation to pay such amounts  shall be deemed to be a part of the  Obligations
secured hereunder.

         13. VCOC shall  indemnify  and hold harmless each Lender and each Agent
and any other Person acting hereunder for all losses,  costs,  damages, fees and
expenses  whatsoever  associated  with the  exercise  of the powers of  attorney
granted herein and shall release each Lender and each Agent and any other Person
acting hereunder from all liability whatsoever for the exercise of the foregoing
powers of attorney and all actions taken  pursuant  thereto,  except,  in either
event,  in the case of gross  negligence  or  willful  misconduct  by the Person
seeking  indemnification  as determined by a final order of a court of competent
jurisdiction.

         14.      VCOC agrees that the rights of the Lenders and the
Agents, or any of them, under this Agreement, the Loan Agreement,
any other Loan Document, or any other contract or agreement now
or hereafter in existence among the Lenders and the Agents and
VCOC or any Subsidiary of VCOC and any other obligors thereunder,
or any of them,  shall be  cumulative,  and that each  Lender and 

                                       9



each Agent may from time to time  exercise such rights and such remedies as such
Person or Persons may have thereunder and under the laws of the United States or
any state,  as  applicable,  in the  manner and at the time that such  Person or
Persons in its or their  sole  discretion  desire,  subject to the terms of such
agreements.  VCOC further expressly agrees that the Lenders and the Agents shall
in no event  be under  any  obligation  to  resort  to any  Collateral  prior to
exercising any other rights that the Lenders and the Agents, or any of them, may
have against VCOC or any Subsidiary of VCOC or any other obligor or any of their
respective properties, nor shall the Lenders and the Agents be obliged to resort
to any  other  collateral  or  security  for the  Obligations,  other  than  the
Collateral,  prior to any  exercise  of  rights  against  VCOC and its  property
hereunder.

         15.  VCOC  hereby  acknowledges  that the  Obligations  arose  out of a
commercial transaction, and agrees that if a Default shall occur, the Collateral
Agent shall have the right to immediate  possession without notice or a hearing,
and hereby knowingly and intelligently  waives any and all rights it may have to
any notice and posting of a bond by the Lenders and the Agents,  or any of them,
prior to seizure by the Collateral Agent or any of its  transferees,  assigns or
successors in interest, of the Collateral or any portion thereof.

         16. No transfer or renewal,  extension,  assignment or  termination  of
this Agreement or of the Loan Agreement or of any other Loan Document, or of any
instrument  or document  executed and  delivered by VCOC or any other obligor to
the Lenders and the Agents, or any of them, nor additional  advances made by the
Lenders  and the  Agents,  or any of them,  to VCOC,  nor the  taking of further
security,  nor the  retaking or  re-delivery  of the  Collateral  to VCOC by the
Lenders and the Agents, or any of them, nor any other act of the Lenders and the
Agents, or any of them, shall release VCOC from any Obligation, except a release
or discharge  executed in writing by the Collateral Agent in accordance with the
Loan Agreement with respect to such Obligation or upon full payment, performance
and satisfaction of all Obligations and termination of the Commitments.  None of
the Lenders or the Agents shall by any act,  delay,  omission or  otherwise,  be
deemed to have waived any of its or their rights or remedies  hereunder,  unless
such waiver is in writing and signed by the Collateral  Agent in accordance with
the Loan  Agreement and then only to the extent  therein set forth.  A waiver by
the  Lenders  and the  Agents,  or any of them,  of any  right or  remedy on any
occasion  shall not be  construed  as a bar to the exercise of any such right or
remedy which any such Person would otherwise have had on any other occasion.

         17.      Neither this Agreement nor any of VCOC's rights or
obligations hereunder may be assigned by VCOC to any other Person 

                                       10


without  the  consent of all the Agents and the  Lenders.  VCOC agrees that this
Agreement or the rights  hereunder may in the  discretion of the Lenders and the
Agents,  as applicable,  be assigned in whole or in part in connection  with any
assignment  of the Loan  Agreement or the  Indebtedness  evidenced  thereby,  as
permitted thereunder. In the event this Agreement or the rights hereunder are so
assigned by any of the Lenders, the Co-Agents,  the Agents, the Managing Agents,
the Administrative  Agent, the Documentation Agent and the Collateral Agent, the
terms  "Lenders",  "Co-Agents",  "Agents",  "Managing  Agents",  "Administrative
Agent",  "Documentation  Agent" or "Collateral Agent" wherever used herein shall
be deemed, as applicable, to refer to and include any such assignee.

         18. The Collateral Agent is hereby authorized to date this Agreement as
of the  date  signed  by  VCOC.  This  Agreement  shall  apply  to and  bind the
respective  successors  and  assigns  of VCOC and  inure to the  benefit  of the
successors and permitted assigns of the Lenders and the Agents.

         19.  All  notices  and  other  communications   required  or  permitted
hereunder  shall be in writing  and shall be given in the manner  prescribed  in
Section 11.1 of the Loan Agreement.

         20.  THE   PROVISIONS  OF  THIS   AGREEMENT   SHALL  BE  CONSTRUED  AND
INTERPRETED, AND ALL RIGHTS AND OBLIGATIONS OF THE PARTIES HERETO DETERMINED, IN
ACCORDANCE  WITH  THE  INTERNAL  LAWS OF THE  STATE OF NEW  YORK  APPLICABLE  TO
CONTRACTS  MADE AND TO BE  PERFORMED IN THE STATE OF NEW YORK.  THIS  AGREEMENT,
TOGETHER WITH ALL DOCUMENTS REFERRED TO HEREIN, CONSTITUTES THE ENTIRE AGREEMENT
AMONG VCOC,  THE LENDERS  AND THE AGENTS WITH  RESPECT TO THE MATTERS  ADDRESSED
HEREIN,  AND MAY NOT BE MODIFIED EXCEPT BY A WRITING  EXECUTED BY THE COLLATERAL
AGENT  (WITH THE  REQUISITE  CONSENT  OF THE  LENDERS  AS  PROVIDED  IN THE LOAN
AGREEMENT) AND VCOC AND DELIVERED BY THE COLLATERAL  AGENT TO VCOC IN ACCORDANCE
WITH THE LOAN AGREEMENT.

         21. If any  paragraph or part thereof of this  Agreement  shall for any
reason be held or adjudged to be invalid,  illegal or unenforceable by any court
of  competent  jurisdiction,  such  paragraph  or part  thereof  so  adjudicated
invalid,  illegal  or  unenforceable  shall be  deemed  separate,  distinct  and
independent,  and the remainder of this Agreement shall remain in full force and
effect and shall not be affected by such holding or adjudication.

         22.  Notwithstanding  anything  herein  which may be  construed  to the
contrary,  no action shall be taken by the Collateral  Agent with respect to the
Licenses issued by the FCC or any  governmental  or other  authority  unless and
until all  requirements  of Applicable  Law  requiring  notice to, or consent or
approval of such action by,  the FCC or any  governmental  or other  authority,

                                       11


have been satisfied, including, without limitation, any required approval of the
FCC under the Federal  Communications Act of 1934 as amended, and any applicable
rules and regulations thereunder,  including,  without limitation, the provision
for ten  (10)  days'  notice  to the FCC and to VCOC of any such  action  to the
extent required by 47 C.F.R. ss. 22.937(f).  VCOC covenants that upon request of
the Collateral  Agent it will cause to be filed such  applications and take such
other action as may be requested by the  Collateral  Agent to obtain  consent or
approval of the FCC or any governmental or other authority which has granted any
License to VCOC to any action  contemplated by this Agreement and to give effect
to the Security Interest of the Collateral Agent, including, without limitation,
the  execution  of an  application  for consent by the FCC to an  assignment  or
transfer  involving a change in ownership or control  pursuant to the provisions
of the Federal Communications Act of 1934 as amended.

         23. This Agreement may be executed in any number of counterparts,  each
of which shall be deemed to be an original,  but all such separate  counterparts
shall together constitute but one and the same instrument.

         24. The parties acknowledge their intent that, upon the occurrence of a
Default,  the Collateral Agent shall receive, to the fullest extent permitted by
Applicable Law and  governmental  policy  (including,  without  limitation,  the
rules,  regulations and policies of the FCC), all rights  necessary or desirable
to obtain, use or sell the Collateral, and to exercise all remedies available to
it under  this  Agreement,  the  Uniform  Commercial  Code as in  effect  in any
applicable   jurisdiction,   or  other   Applicable  Law.  The  parties  further
acknowledge  and agree  that,  in the event of  changes  in law or  governmental
policy  occurring  subsequent to the date hereof,  that affect in any manner the
Collateral  Agent's rights of access to, or use or sale of, the  Collateral,  or
the procedures necessary to enable the Collateral Agent to obtain such rights of
access, use or sale, the Collateral Agent and VCOC shall amend this Agreement in
such  manner as the  Collateral  Agent  shall  reasonably  request,  in order to
provide  the  Collateral  Agent  such  rights to the  greatest  extent  possible
consistent with Applicable Law and governmental policy.

         25. Each reference  herein to any right granted to,  benefit  conferred
upon or power exercisable by the "Collateral  Agent" shall be a reference to the
Collateral  Agent for the benefit of all the  Lenders  and the Agents,  and each
action taken or right exercised  hereunder shall be deemed to have been so taken
or exercised by the Collateral Agent for the benefit of and on behalf of all the
Lenders and the Agents.

                                       12



         26.  Notwithstanding  anything  herein  which may be  construed  to the
contrary, any right to indemnification hereunder, including, without limitation,
rights  pursuant to Section 12 hereof,  shall  survive the  termination  of this
Agreement and the payment and performance of all other Obligations.
