made  available  to the  Borrower by the  Administrative  Agent in like funds as
received by the Administrative Agent.

                  (b) The  Borrower  may borrow under the Delayed Draw Term Loan

Borrower,  the Administrative Agent shall promptly notify each Delayed Draw Term

its pro rata share of each borrowing  available to the Administrative  Agent for
the account of the Borrower at the Funding  Office prior to 12:00 Noon, New York

                  2.3  Revolving  Credit  Commitments.  Subject to the terms and
conditions  hereof,  each  Revolving  Credit  Lender  severally  agrees  to make
revolving credit loans  ("Revolving  Credit Loans") to the Borrower from time to
time during the Revolving  Credit  Commitment  Period in an aggregate  principal
amount at any one time  outstanding  not  exceeding  the amount of such Lender's
Revolving Credit Commitment,  provided,  that the aggregate  principal amount of
Tranche A Term  Loans,  Delayed  Draw Term  Loans,  Revolving  Credit  Loans and
Conversion  Term  Loans  shall  not  exceed   $300,000,000   until  the  Initial

Commitment  Period the  Borrower may use the  Revolving  Credit  Commitments  by
borrowing,  prepaying  the  Revolving  Credit  Loans in  whole  or in part,  and
reborrowing,  all in  accordance  with the  terms  and  conditions  hereof.  The
Revolving  Credit  Loans may from time to time be  Eurodollar  Loans or ABR Rate
Loans, as determined by the Borrower and notified to the Administrative Agent in
accordance  with Sections 2.4 and 2.14,  provided that no Revolving  Credit Loan
shall be made as a Eurodollar  Loan after the day that is one month prior to the
Revolving Credit Termination Date.

                  2.4 Procedure for Revolving Credit Borrowing. The Borrower may
borrow  under the  Revolving  Credit  Commitments  during the  Revolving  Credit

                                                                              33


York City time, (a) three Business Days prior to the requested  Borrowing  Date,
in the case of Eurodollar  Loans, or (b) one Business Day prior to the requested
Borrowing  Date, in the case of ABR Loans,  and which notice may be by telephone
(to be confirmed in writing)),  specifying  (i) the amount and Type of Revolving
Credit Loans to be borrowed,  (ii) the requested Borrowing Date and (iii) in the
case of Eurodollar  Loans, the amount of the requested  Eurodollar Loans and the
length  of the  initial  Interest  Period  therefor.  Each  borrowing  under the
Revolving Credit  Commitments  shall be in an amount equal to (x) in the case of
ABR Loans,  $1,000,000 or a whole  multiple  thereof (or, if the then  aggregate
Available  Revolving Credit  Commitments are less than  $1,000,000,  such lesser
amount) and (y) in the case of Eurodollar Loans,  $5,000,000 or a whole multiple
of  $1,000,000  in excess  thereof.  Upon  receipt of any such  notice  from the
Borrower,  the Administrative  Agent shall promptly notify each Revolving Credit
Lender  thereof.  Each  Revolving  Credit Lender will make the amount of its pro
rata  share of each  borrowing  available  to the  Administrative  Agent for the
account of the Borrower at the Funding Office prior to 12:00 Noon, New York City
time,  on the  Borrowing  Date  requested by the  Borrower in funds  immediately
available  to the  Administrative  Agent.  Such  borrowing  will  then  be  made
available to the Borrower by the Administrative  Agent in like funds as received
by the Administrative Agent.

                  2.5 Extension of Delayed Draw Term Loan Commitment Termination
Date.  (a)(i) The Borrower may request,  in a notice given as herein provided to
the Administrative Agent during the 30 day period commencing on the date that is
60 days prior to the Delayed Draw Term Loan Commitment  Termination Date then in
effect (the "Existing Delayed Draw Term Loan Commitment Termination Date"), that
the Delayed Draw Term Loan Commitment Termination Date be extended, which notice
shall specify the new Delayed Draw Term Loan Commitment  Termination Date (which
shall be not more  than 364 days  after  the  Existing  Delayed  Draw  Term Loan
Commitment  Termination  Date) to be in effect  following  such  extension  (the
"Requested  Delayed  Draw Term Loan  Commitment  Termination  Date");  provided,
however,  that the Borrower  may request only one such  extension of the Delayed
Draw Term Loan  Commitment  Termination  Date.  The  Administrative  Agent shall
promptly notify each Delayed Draw Term Loan Lender of such request. Each Delayed
Draw Term Loan Lender,  acting in its sole  discretion,  shall, not later than a
date 20 days after such request from the  Borrower,  notify the Borrower and the
Administrative  Agent in writing of its  election to extend or not to extend the
Delayed Draw Term Loan Commitment  Termination  Date with respect to its Delayed
Draw Term Loan  Commitment.  Any Delayed  Draw Term Loan Lender  which shall not
timely  notify the  Borrower  and the  Administrative  Agent of its  election to
extend the Delayed Draw Term Loan Commitment Termination Date shall be deemed to
have  elected not to extend the Delayed  Draw Term Loan  Commitment  Termination
Date with  respect to its Delayed  Draw Term Loan  Commitment  (any Delayed Draw
Term Loan Lender who timely notifies the Borrower and the  Administrative  Agent
of an election  not to extend its  Delayed  Draw Term Loan  Commitment,  and any
Lender so deemed  to have  elected  not to  extend  its  Delayed  Draw Term Loan
Commitment  being  referred to as a  "Terminating  Delayed  Draw  Lender").  The
election of any Lender to agree to a requested  extension shall not obligate any
other Lender to agree.

                  (ii) If and only if  Lenders  holding  Delayed  Draw Term Loan
Commitments  that aggregate at least 75% of the aggregate  amount of the Delayed
Draw Term Loan

                                                                              34

Commitments  on the date of the notice  delivered  by the  Borrower  pursuant to
subparagraph  (a)(i) above (including  Delayed Draw Term Loan Commitments of all
Terminating  Delayed  Draw Term Loan  Lenders  on such date)  shall have  agreed
during the 20 day period referred to in such  subparagraph  (a)(i) to extend the
Existing  Delayed  Draw  Term Loan  Commitment  Termination  Date,  then (A) the
Delayed Draw Term Loan  Commitments  of the Delayed Draw Term Loan Lenders other
than Terminating  Delayed Draw Term Loan Lenders (the  "Continuing  Delayed Draw
Term Loan Lenders") shall, subject to the other provisions of this Agreement, be
extended to the Requested  Delayed Draw Term Loan  Commitment  Termination  Date
specified in the notice from the Borrower, and as to such Delayed Draw Term Loan
Lenders the term "Delayed Draw Term Loan Commitment  Termination  Date", as used
herein,  shall on and  after  the date as of which the  requested  extension  is
effective  mean such  Requested  Delayed Draw Term Loan  Commitment  Termination
Date,  provided  that if such date is not a Business  Day,  then such  Requested
Delayed Draw Term Loan Commitment  Termination  Date shall be the next preceding
Business Day and (B) the Delayed Draw Term Loan  Commitments of the  Terminating
Delayed Draw Lenders shall  continue  until the Existing  Delayed Draw Term Loan
Commitment Termination Date, and shall then terminate, and as to the Terminating
Delayed Draw Lenders,  the term "Delayed Draw Term Loan  Commitment  Termination
Date",  as used herein,  shall continue to mean such Existing  Delayed Draw Term
Loan Commitment Termination Date.

                  (b) In the event that the  Delayed  Draw Term Loan  Commitment
Termination  Date shall  have been  extended  for the  Continuing  Delayed  Draw
Lenders in accordance  with  paragraph  (a) above and, in  connection  with such
extension,  there are Terminating Delayed Draw Lenders, the Borrower may, at its
own expense,  require any Terminating Delayed Draw Lender to transfer and assign
in whole or in part,  without  recourse (in accordance  with Section 9.6) all or
part of its interests,  rights and obligations  under the Delayed Draw Term Loan
Facility to an assignee (which assignee may be another Lender, if another Lender
accepts such  assignment)  that shall assume such assigned  obligations and that
shall  agree  that its  Delayed  Draw Term Loan  Commitment  will  expire on the
Delayed  Draw Term Loan  Commitment  Termination  Date in effect for  Continuing
Delayed  Draw  Term Loan  Lenders  pursuant  to such  paragraph  (a);  provided,
however,  that (i) the  Borrower  shall have  received a written  consent of the
Administrative  Agent in the  case of an  assignee  that is not a Lender  (which
consent shall not  unreasonably be withheld) and (ii) the assigning Lender shall
have received  from the Borrower or such  assignee  full payment in  immediately
available  funds of the  principal of and  interest  accrued to the date of such
payment on the Loans made by it  hereunder  to the extent that such Delayed Draw
Term  Loans are  subject to such  assignment  and all other  amounts  owed to it
hereunder  (including any amounts that would be payable to the assigning  Lender
pursuant to Section 2.22 if such assignment were,  instead,  a prepayment of the
Delayed  Draw  Term  Loans of such  Delayed  Draw Term  Loan  Lender).  Any such
assignee's  initial Delayed Draw Term Loan Commitment  Termination Date shall be
the Delayed Draw Term Loan Commitment  Termination Date in effect at the time of
such assignment for the Continuing Delayed Draw Term Loan Lenders.  The Borrower
shall  not have  any  right  to  require  a  Lender  to  assign  any part of its
interests,  rights  and  obligations  under  this  Agreement  pursuant  to  this
paragraph (b) unless it has notified such Lender of its intention to require the
assignment thereof at least five days prior to the proposed assignment date.

                  2.6  Conversion  Term  Loans.  (a)  Subject  to the  terms and
conditions  hereof,  the Borrower may, on the Delayed Draw Term Loan  Commitment
Termination  Date with respect to any Lender,  convert any  outstanding  Delayed
Draw Term Loans of such Lender, or a portion thereof, to term loans ("Conversion
Term Loans");  provided,  that if the Borrower  elects to convert any portion of
the  Delayed  Draw  Term  Loans of any  Lender  on the  Delayed  Draw  Term Loan
Commitment Termination Date applicable to such Lender, it must elect to the same
percentage  portion  of the  outstanding  Delayed  Draw Term Loans of each other
Lender having the same Delayed Draw Term Loan Commitment  Termination Date. Such
conversion  shall be  requested  by the  Borrower by  irrevocable  notice to the
Administrative  Agent (which notice must be received by the Administrative Agent
prior to 12:00 Noon,  New York City time,  (a) three Business Days prior to such
Delayed Draw Term Loan  Commitment  Termination  Date, if all or any part of the
Conversion Term Loans are to be Eurodollar  Loans, or (b) one Business Day prior
to  such  Delayed  Draw  Term  Loan  Commitment  Termination  Date,  otherwise),
specifying  (i) the  amount  of  Delayed  Draw  Term  Loans to be  converted  to
Conversion  Term Loans,  (ii) the initial Type of the Conversion  Term Loans and
(iii) in the case of Conversion  Term Loans that are to be initially  Eurodollar
Loans,  the  amount  thereof  and the  length  of the  initial  Interest  Period
therefor.  Upon receipt of any such notice from the Borrower, the Administrative
Agent shall promptly notify each affected Delayed Draw Term Loan Lender thereof.
On the Delayed Draw Term Loan Commitment  Termination Date,  outstanding Delayed
Draw Term Loans shall be converted to Conversion  Term Loans in accordance  with
such notice.

                  (b) Subject to the terms and conditions  hereof,  the Borrower
may, on the Revolving Credit Termination Date, convert any outstanding Revolving
Credit Loans to Conversion Term Loans; provided,  that if the Borrower elects to
convert any portion of the Revolving Credit Loans of any Lender on the Revolving
Credit  Termination  Date, it must elect to the same  percentage  portion of the
outstanding  Revolving Credit Loans of each other Revolving Credit Lender.  Such
conversion  shall be  requested  by the  Borrower by  irrevocable  notice to the
Administrative  Agent (which notice must be received by the Administrative Agent
prior to 12:00 Noon,  New York City time,  (a) three  Business Days prior to the
Revolving  Credit  Termination  Date, if all or any part of the Conversion  Term
Loans are to be Eurodollar Loans, or (b) one Business Day prior to the Revolving
Credit  Termination  Date,  otherwise),  specifying  (i) the amount of Revolving
Credit Loans to be converted to Conversion Term Loans,  (ii) the initial Type of
the  Conversion  Term Loans and (iii) in the case of Conversion  Term Loans that
are to be initially  Eurodollar  Loans, the amount thereof and the length of the
initial  Interest  Period  therefor.  Upon  receipt of any such  notice from the
Borrower,  the Administrative  Agent shall promptly notify each Revolving Credit
Lender.  On the  Revolving  Credit  Termination  Date or Delayed  Draw Term Loan
Commitment  Termination  Date,  outstanding  Revolving  Credit  Loans  shall  be
converted to Conversion Term Loans in accordance with such notice.

                  2.7  Optional  Term  Loans.  (a)  Subject  to  the  terms  and
conditions  hereof,  the Borrower may, with the consent of the Required Lenders,
at any time and from time to time prior to December 31, 2001,  establish  one or
more  additional  term loan tranches  (each,  an "Optional  Term Loan  Tranche")
pursuant to which term loans  ("Optional Term Loans") may be made. Each Optional
Term Loan Tranche shall be in a principal  amount of at least



<PAGE>
                                                                              36

$50,000,000,  and all Optional Term Loan Tranches shall not exceed  $400,000,000
in the aggregate.  The Borrower shall request the  establishment  of an Optional
Term Loan Tranche by delivery to the  Administrative  Agent of a written request
therefor (an "Optional Term Loan Request")  which shall be promptly  distributed
by the  Administrative  Agent to the Lenders.  Each  Optional  Term Loan Request
shall (i) set forth the aggregate  principal  amount of the  requested  Optional
Term Loan Tranche and the Applicable Margin (or, if applicable,  the formula for
the calculation  thereof) and the commitment fee rate, if any, applicable to the
Optional  Term Loans to be made  under  such  Optional  Term Loan  Tranche,  the
amortization  and maturity  date of such  Optional  Term Loans and the borrowing
procedures relating to the borrowing by the Borrower of such Optional Term Loans
and (ii) be accompanied by such  information as the  Administrative  Agent shall
reasonably  request for use in syndication of the requested Optional Term Loans.
All Optional Term Loans shall (I) have a Weighted  Average Life  (calculated  on
the date the related Optional Term Loan Tranche shall become  effective) that is
at least as long as the then Weighted  Average Life (calculated on such date) of
the Revolving Credit Commitments and the Term Loans, taken as a whole, (II) have
a final  scheduled  maturity  date on or after  December  31,  2006,  (III) bear
interest  at rates no higher than those  applicable  to the Tranche A Term Loans
and (IV) otherwise be subject to the same terms and conditions as the other Term
Loans outstanding hereunder.

                  (b) The Borrower may offer to any existing  Lender,  or to one
or more additional banks,  financial  institutions or other entities  reasonably
acceptable to the Administrative Agent, the opportunity to participate in all or
a portion of an Optional Term Loan Tranche.

                  (c) The  effectiveness of any Optional Term Loan Tranche shall
be contingent upon (i) execution and delivery by the  Administrative  Agent, the
Borrower and each Lender  providing  Optional Term Loan  Commitments  under such
Optional Term Loan Tranche of an Optional Term Loan  Amendment  relating to such
Optional Term Loan Tranche and (ii) receipt by the Administrative  Agent of such
corporate  resolutions  and  officer's  certificates  of the  Borrower and legal
opinions of counsel to the Borrower as the Administrative Agent shall reasonably
request with respect  thereto,  in each case, in form and  substance  reasonably
satisfactory to the Administrative  Agent. In the case of any Optional Term Loan
Amendment  executed by any Person that was not  theretofore  a Lender,  upon the
effectiveness  thereof  such  Person  shall  be a  party  hereto  and  a  Lender
hereunder.  The Borrower and the Administrative Agent agree to negotiate in good
faith any  Optional  Term Loan  Amendment  relating  to any  Optional  Term Loan
Tranche.

                  (d) No Lender shall have any  obligation to participate in any
Optional Term Loan Tranche unless it agrees to do so in its sole discretion.

                  2.8  Repayment  of Loans.  (a) The  Tranche A Term Loans shall
mature in 16  consecutive  quarterly  installments,  commencing on September 30,
2002,  each of which shall equal the  percentage  set forth below  opposite such
installment  of the aggregate  principal  amount of Tranche A Term Loans of each
Lender outstanding on the last day of the Tranche A Term Loan Commitment Period:

Term Loan  Amendment  executed for such Optional  Term Loan Tranche  pursuant to
Section 2.7.

                  (d) The Delayed Draw Term Loans of each Lender,  to the extent
not converted to Conversion Term Loans on the applicable  Delayed Draw Term Loan
Commitment Termination Date, shall mature and be payable in full on such date.

                  (e) The Revolving  Credit Loans of each Lender,  to the extent
not converted to Conversion Term Loans on the Revolving Credit Termination Date,
shall mature and be payable in full on such date.

                  2.9  Repayment  of Loans;  Evidence of Debt.  (a) The Borrower
hereby  unconditionally  promises  to pay to the  Administrative  Agent  for the
account of the appropriate  Revolving Credit Lender or Term Loan Lender,  as the
case may be, (i) the then unpaid  principal amount of each Revolving Credit Loan
of such Revolving Credit Lender on the applicable  Revolving Credit  Termination
Date (or such earlier date on which the Loans become due and payable pursuant to
Section 7), to the extent  such  Revolving  Credit  Loans are not  converted  to
Conversion  Term Loans on such date and (ii) the  principal  amount of each Term
Loan of such Term Loan  Lender in  installments  according  to the  amortization
schedule  set forth in Section 2.8 (or on such  earlier  date on which the Loans
become due and  payable  pursuant  to Section 7). The  Borrower  hereby  further
agrees to pay interest on the unpaid  principal amount of the Loans from time to
time outstanding from the date hereof until payment in full thereof at the rates
per annum, and on the dates, set forth in Section 2.16.

                  (b) Each Lender shall  maintain in  accordance  with its usual
practice an account or accounts evidencing  indebtedness of the Borrower to such
Lender resulting from each Loan of such Lender from time to time,  including the
amounts of principal  and interest  payable and paid to such Lender from time to
time under this Agreement.

                  (c) The Administrative Agent, on behalf of the Borrower, shall
maintain the Register pursuant to Section 9.6(e),  and a subaccount  therein for
each  Lender,  in which  shall be  recorded  (i) the  amount  of each  Loan made
hereunder and any Note  evidencing such Loan, the Type thereof and each Interest
Period applicable thereto,  (ii) the amount of any principal or interest due and
payable or to become due and payable from the Borrower to each Lender  hereunder
and  (iii)  both the  amount of any sum  received  by the  Administrative  Agent
hereunder from the Borrower and each Lender's share thereof.

                  (d) The entries  made in the Register and the accounts of each
Lender  maintained  pursuant to Section 2.9(b) shall, to the extent permitted by
applicable  law, be prima facie  evidence  of the  existence  and amounts of the
obligations  of the  Borrower  therein  recorded;  provided,  however,  that the
failure of any Lender or the  Administrative  Agent to maintain  the Register or
any such  account,  or any error  therein,  shall not in any  manner  affect the
obligation of the Borrower to repay (with applicable interest) the Loans made to
such Borrower by such Lender in accordance with the terms of this Agreement.

                (e)  The  Borrower  agrees  that,  upon  the  request  to  the
Administrative  Agent by any Lender,  the  Borrower  will execute and deliver to
such  Lender a  promissory  note of the  Borrower  evidencing  any Term Loans or
Revolving Credit Loans, as the case may be, of such Lender, substantially in the
forms of  Exhibit  G-1 (a  "Term  Note")  or G-2 (a  "Revolving  Credit  Note"),
respectively, with appropriate insertions as to date and principal amount.

                  2.10  Commitment  Fees, etc. (a) The Borrower agrees to pay to
the  Administrative  Agent for the  account of each  Revolving  Credit  Lender a
commitment  fee for the  period  from  and  including  the  Closing  Date to but
excluding the last day of the Revolving Credit  Commitment  Period,  computed at
the Commitment  Fee Rate on the average daily amount of the Available  Revolving
Credit  Commitment  of such Lender  during the period for which payment is made,
payable quarterly in arrears on the last day of each March, June,  September and
December and on the Revolving Credit  Termination Date,  commencing on the first
of such dates to occur after the date hereof.

                  (b) The Borrower agrees to pay to the Administrative Agent for
the account of each Tranche A Term Loan Lender a  commitment  fee for the period
from and including the Closing Date to but excluding the last day of the Tranche
A Term  Loan  Commitment  Period,  computed  at the  Commitment  Fee Rate on the
average  daily amount of the  Available  Tranche A Term Loan  Commitment of such
Lender during the period for which payment is made, payable quarterly in arrears
on the last day of each March, June, September, and December and on the last day
of the Tranche A Term Loan  Commitment  Period,  commencing on the first of such
dates to occur after the date hereof.

                  (c) The Borrower agrees to pay to the Administrative Agent for
the  account of each  Delayed  Draw Term Loan  Lender a  commitment  fee for the
period from and  including the Closing Date to but excluding the last day of the
Delayed Draw Term Loan Commitment Period, computed at the Commitment Fee Rate on
the average daily amount of the Available  Delayed Draw Term Loan  Commitment of
such Lender  during the period for which payment is made,  payable  quarterly in
arrears on the last day of each March, June, September,  and December and on the
last day of the Delayed  Draw Term Loan  Commitment  Period,  commencing  on the
first of such dates to occur after the date hereof.

                  (d) The Borrower agrees to pay to the Administrative Agent the
fees in the  amounts  and on the dates from time to time agreed to in writing by
the Borrower and the Administrative Agent.

                  2.11  Termination  or Reduction of  Commitments.  The Borrower
shall have the  right,  upon not less than three  Business  Days'  notice to the
Administrative Agent, to terminate any of the Commitments or, from time to time,
to  reduce  the  amount  of  any of  the  Commitments;  provided  that  no  such
termination or reduction of Revolving Credit  Commitments shall be permitted if,
after giving effect thereto and to any prepayments of the Revolving Credit Loans
made on the effective date thereof, the aggregate  outstanding  principal amount
of Revolving Credit Loans would exceed the Total Revolving  Credit  Commitments.
Any  such  reduction  shall be in an  amount  equal  to  $1,000,000,  or a whole
multiple thereof,  and shall reduce permanently the applicable  Commitments then
in effect.

Optional  reductions of the Commitments  under the Tranche A Term Loan Facility,
the Delayed Draw Term Loan Facility and the Revolving Credit Facility  occurring
prior to the first  anniversary  of the Closing Date shall be  accompanied  by a
reduction fee equal to 3% of the amount of such reduction.

                  2.12  Optional  Prepayments.  The Borrower may at any time and
from time to time  prepay the  Loans,  in whole or in part,  without  premium or
penalty  except  as  provided  in  the  last  sentence  of  this  Section,  upon
irrevocable notice delivered to the Administrative Agent at least three Business
Days prior thereto in the case of Eurodollar Loans and at least one Business Day
prior thereto in the case of ABR Loans,  which notice shall specify the date and
amount of prepayment  and whether the  prepayment is of Eurodollar  Loans or ABR
Loans; provided,  that if a Eurodollar Loan is prepaid on any day other than the
last day of the Interest Period applicable thereto,  the Borrower shall also pay
any amounts owing pursuant to Section 2.22.  Upon receipt of any such notice the
Administrative  Agent shall promptly notify each relevant Lender thereof. If any
such  notice is given,  the amount  specified  in such  notice  shall be due and
payable on the date  specified  therein,  together  with  (except in the case of
Revolving Credit Loans which are ABR Loans) accrued interest to such date on the
amount  prepaid.  Partial  prepayments of Term Loans and Revolving  Credit Loans
shall be in an aggregate  principal  amount of  $1,000,000  or a whole  multiple
thereof.  Optional  prepayments of the Term Loans  occurring  prior to the first
anniversary  of the Closing Date shall be  accompanied by a prepayment fee equal
to 3% of the amount of such prepayment.

                  2.13 Mandatory Prepayments and Commitment  Reductions;  Change
of Control. (a) Unless the Required Prepayment Lenders shall otherwise agree, if
the  Borrower  makes any  Specified  Prepayment,  an amount  equal to the Credit
Agreement  Portion  thereof  shall  be  applied  on the  date of such  Specified
Prepayment  toward the  prepayment  of the Term Loans and the  reduction  of the
Revolving Credit Commitments as set forth in Section 2.13(d).

                  (b) Unless the Required  Prepayment  Lenders  shall  otherwise
agree, if on any date the Borrower or any of its Restricted  Subsidiaries  shall
receive Net Cash Proceeds from any Asset Sale or Recovery  Event by the Borrower
or its  Restricted  Subsidiaries  then,  unless a  Reinvestment  Notice shall be
delivered in respect thereof within five Business Days after receipt of such Net
Cash  Proceeds,  such Net Cash Proceeds shall be applied on such date toward the
prepayment  of  the  Term  Loans  and  the  reduction  of the  Revolving  Credit
Commitments  as  set  forth  in  Section  2.13(d);   provided,   that,  on  each
Reinvestment  Prepayment  Date, an amount equal to the  Reinvestment  Prepayment
Amount with respect to the relevant  Reinvestment  Event shall be applied toward
the  prepayment  of the Term Loans and the  reduction  of the  Revolving  Credit
Commitments as set forth in Section 2.13(d). If at any time the aggregate amount
of Net  Cash  Proceeds  in  respect  of which  Reinvestment  Notices  have  been
delivered  and  which  have  not  been   reinvested  in  accordance   with  such
Reinvestment  Notices shall exceed  $25,000,000 for a period of 90 days, then on
or before such 90th day of such period,  the Borrower  shall deliver such excess
over $25,000,000 to the Collateral Agent to be held by it in accordance with the
Collateral Agency and Intercreditor Agreement.

                                                                              41

                  (c) Unless the Required  Prepayment  Lenders  shall  otherwise
agree,  if, for any fiscal year of the Borrower  commencing with the fiscal year
ending  December 31, 2002,  there shall be Excess Cash Flow, the Borrower shall,
on the relevant Excess Cash Flow Application Date, apply 50% of such Excess Cash
Flow toward the  prepayment  of the Term Loans as set forth in Section  2.13(d).
Each  such  prepayment  and  commitment  reduction  shall  be made on a date (an
"Excess Cash Flow  Application  Date") no later than five days after the earlier
of (i) the date on which the financial statements of the Borrower referred to in
Section  6.1(a),  for the fiscal year with respect to which such  prepayment  is
made,  are  required  to be  delivered  to the  Lenders  and (ii) the date  such
financial statements are actually delivered.

                  (d) Amounts to be applied in connection  with  prepayments and
Commitment  reductions  made  pursuant to this  Section and Section 6.6 shall be
applied,  first,  to the  prepayment  of  the  Term  Loans,  second,  to  reduce
permanently the Revolving Credit  Commitments and, third, to reduce  permanently
any Tranche A Term Loan  Commitments,  Delayed  Draw Term Loan  Commitments  and
Optional Term Loan Commitments then unused and in effect,  pro rata according to
the  respective  amounts of Tranche A Term Loan  Commitments,  Delayed Draw Term
Loan Commitments and Optional Term Loan  Commitments.  Any such reduction of the
Revolving Credit Commitments shall be accompanied by prepayment of the Revolving
Credit Loans to the extent,  if any,  that the aggregate  outstanding  principal
amount of Revolving Credit Loans exceed the amount of the Total Revolving Credit
Commitments as so reduced.  The  application of any prepayment  pursuant to this
Section  shall be made first to ABR Loans and second to Eurodollar  Loans.  Each
prepayment  of the Loans  under this  Section  (except in the case of  Revolving
Credit Loans that are ABR Loans) shall be accompanied by accrued interest to the
date of such  prepayment  on the  amount  prepaid.  No  prepayment  fee shall be
payable in connection  with any prepayment or Commitment  reduction  required by
paragraphs (a) through (c) above.

                  (e) Any amounts applied to Loans pursuant to Section  2.13(a),
Section  2.13(b) or Section  2.13(c) which are  Eurodollar  Loans shall,  at the
option of the  Borrower,  be applied to prepay  the Loans  which are  Eurodollar
Loans  immediately  and/or  shall be  deposited  in the  Prepayment  Account (as
defined  below).  The Agent shall  apply any cash  deposited  in the  Prepayment
Account to prepay the Loans  which are  Eurodollar  Loans on the last day of the
Interest Period  therefor (or, at the direction of the Borrower,  on any earlier
date) until all outstanding  Loans which are Eurodollar  Loans have been prepaid
or until all cash on  deposit  in the  Prepayment  Account  (including,  without
limitation,  interest  earned  thereon)  with  respect  to such  Loans  has been
exhausted.  For purposes of this Agreement,  the term "Prepayment Account" shall
mean an account  established by the Borrower with the  Administrative  Agent and
over which the  Administrative  Agent shall have exclusive dominion and control,
including  the right of  withdrawal  for  application  in  accordance  with this
Section 2.13(e). The Administrative Agent shall, at the request of the Borrower,
invest amounts on deposit in the  Prepayment  Account in Cash  Equivalents  that
mature on or prior to the last day of the  applicable  Interest  Periods  of the
Eurodollar Loans to be prepaid, provided that (i) the Administrative Agent shall
not be required to make any investment that, in its sole judgment, would require
or cause the Administrative Agent to be in, or would result in any, violation of
any  Requirement  of Law  and  (ii)  the  Administrative  Agent  shall  have  no
obligation to invest amounts on deposit in the  Prepayment  Account if a Default
or Event of Default shall have

                                                                              42

occurred and be  continuing.  The Borrower  shall  indemnify the  Administrative
Agent for any losses  relating  to the  investments  made at the  request of the
Borrower so that the amount available to prepay Eurodollar Loans on the last day
of the  applicable  Interest  Periods  therefor is not less than the amount that
would have been available had no investments  been made. Other than any interest
earned on such  investments,  the  Prepayment  Account shall not bear  interest.
Interest  or  profits,  if any,  on such  investments  shall  be  deposited  and
reinvested as described above and shall be for the account of, and so long as no
Default or Event of Default shall have occurred and be continuing, shall be paid
to, the Borrower.  If the maturity of the Loans has been accelerated pursuant to
Section 7, the Administrative  Agent shall first apply all amounts on deposit in
the Prepayment Account to prepay the outstanding Term Loans and, then, to prepay
any  outstanding  Revolving  Credit  Loans.  The Borrower  hereby  grants to the
Administrative Agent, for its benefit and the benefit of the Lenders, a security
interest in the Prepayment Account to secure the Obligations.

                  (f) In the event that a Change of  Control  shall  occur,  the
Borrower shall promptly give notice thereof to the  Administrative  Agent (which
shall  promptly  notify the Lenders  thereof) and the  Required  Lenders may, in
their sole  discretion,  by notice to the Borrower at any time prior to the date
which is 30 days after such notice to the Administrative Agent of the occurrence
of such Change of Control,  require the Borrower to immediately prepay all Loans
and  terminate  all  Commitments,  and  upon  the  giving  of such  notice,  all
Commitments shall immediately terminate and all Loans, together with accrued and
unpaid interest  thereon and all other amounts payable  hereunder,  shall become
immediately  due and  payable.  Any such  mandatory  prepayment  and  Commitment
reduction made as a result of a Change of Control  occurring  prior to the first
anniversary  of the Closing Date shall be  accompanied by a prepayment fee equal
to  [redacted]  of the  amount  of  such  mandatory  prepayment  and  Commitment
reduction.

                  2.14 Conversion and Continuation Options. (a) The Borrower may
elect from time to time to convert  Eurodollar  Loans to ABR Loans by giving the
Administrative  Agent at least two Business  Days' prior  irrevocable  notice of
such  election  (which notice may be by telephone (to be confirmed in writing)),
provided that any such  conversion  of Eurodollar  Loans may only be made on the
last day of an Interest Period with respect thereto. The Borrower may elect from
time  to  time  to  convert  ABR  Loans  to  Eurodollar   Loans  by  giving  the
Administrative  Agent at least three Business Days' prior irrevocable  notice of
such election  (which  notice shall  specify the length of the initial  Interest
Period  therefor  and which  notice  may be by  telephone  (to be  confirmed  in
writing)),  provided  that  no ABR  Loan  under  a  particular  Facility  may be
converted into a Eurodollar  Loan (i) when any Event of Default has occurred and
is continuing and the Administrative Agent has, or the Majority Facility Lenders
in respect of such Facility have, determined in its or their sole discretion not
to permit such conversions or (ii) after the date that is one month prior to the
final scheduled  termination or maturity date of such Facility.  Upon receipt of
any such notice the  Administrative  Agent shall  promptly  notify each relevant
Lender thereof.

                  (b) Any  Eurodollar  Loan may be  continued  as such  upon the
expiration  of the then  current  Interest  Period with  respect  thereto by the
Borrower  giving  irrevocable  notice  (which  notice may be by telephone (to be
confirmed in writing))  to the  Administrative  Agent,  



<PAGE>
                                                                              43

in accordance with the applicable  provisions of the term "Interest  Period" set
forth in Section 1.1, of the length of the next Interest Period to be applicable
to such Loans,  provided that no Eurodollar Loan under a particular Facility may
be  continued  as such  (i)  when  any  Event of  Default  has  occurred  and is
continuing and the Administrative  Agent has or the Majority Facility Lenders in
respect of such Facility have  determined in its or their sole discretion not to
permit such  continuations or (ii) after the date that is one month prior to the
final  scheduled  termination or maturity date of such  Facility,  and provided,
further,  that if the  Borrower  shall  fail  to give  any  required  notice  as
described  above in this  paragraph  or if such  continuation  is not  permitted
pursuant to the preceding proviso such Loans shall be automatically converted to
ABR Loans on the last day of such then expiring Interest Period. Upon receipt of
any such notice the  Administrative  Agent shall  promptly  notify each relevant
Lender thereof.

                  2.15  Minimum   Amounts  and  Maximum   Number  of  Eurodollar
Tranches.  Notwithstanding  anything  to the  contrary  in this  Agreement,  all
borrowings,  conversions,  continuations and optional  prepayments of Eurodollar
Loans  hereunder and all selections of Interest  Periods  hereunder  shall be in
such amounts and be made  pursuant to such  elections so that,  (a) after giving
effect  thereto,   the  aggregate  principal  amount  of  the  Eurodollar  Loans
comprising  each  Eurodollar  Tranche  shall be equal to  $5,000,000  or a whole
multiple of  $1,000,000  in excess  thereof  and (b) no more than 20  Eurodollar
Tranches shall be outstanding at any one time.

                  2.16 Interest  Rates and Payment  Dates.  (a) Each  Eurodollar
Loan shall bear interest for each day during each  Interest  Period with respect
thereto at a rate per annum equal to the  Eurodollar  Rate  determined  for such
Interest Period plus the Applicable Margin.

                  (b) Each ABR Loan  shall  bear  interest  at a  rate per annum
equal to the ABR plus the Applicable Margin.

                  (c) (i) If all or a  portion  of the  principal  amount of any
Loan shall not be paid when due (whether at the stated maturity, by acceleration
or  otherwise),  the  principal  of such Loan shall bear  interest at a rate per
annum  which is equal to the rate that would  otherwise  be  applicable  thereto
pursuant to the foregoing  provisions of this Section plus 2% and (ii) if all or
a portion of any  interest  payable on any Loan or any  commitment  fee or other
amount  payable  hereunder  shall not be paid when due  (whether  at the  stated
maturity,  by  acceleration or otherwise),  such overdue  amount,  to the extent
permitted by  applicable  law,  shall bear interest at a rate per annum equal to
the rate then  applicable to ABR Loans under the relevant  Facility plus 2% (or,
in the  case of any  such  other  amounts  that do not  relate  to a  particular
Facility,  the rate then  applicable  to ABR Loans  under the  Revolving  Credit
Facility  plus 2%),  in each case,  with  respect to clauses (i) and (ii) above,
from the date of such  non-payment  until  such  amount is paid in full (as well
after as before judgment).

                  (d)  Interest  shall be payable  in  arrears on each  Interest
Payment Date,  provided that interest accruing pursuant to paragraph (c) of this
Section shall be payable from time to time on demand.

                  2.17 Computation of Interest and Fees. (a) Interest,  fees and
commissions  payable  pursuant  hereto  shall be  calculated  on the  basis of a
360-day year for the actual days elapsed, except that, with respect to ABR Loans
the rate of interest on which is calculated on the basis of the Prime Rate,  the
interest  thereon  shall be  calculated  on the basis of a 365- (or 366-, as the
case may be) day year for the actual  days  elapsed.  The  Administrative  Agent
shall as soon as  practicable  notify the Borrower  and the relevant  Lenders of
each  determination  of a Eurodollar  Rate. Any change in the interest rate on a
Loan resulting from a change in the ABR or the Eurocurrency Reserve Requirements
shall  become  effective  as of the opening of business on the day on which such
change becomes effective.  The Administrative Agent shall as soon as practicable
notify the  Borrower  and the  relevant  Lenders of the  effective  date and the
amount of each such change in interest rate.

                  (b)   Each   determination   of  an   interest   rate  by  the
Administrative  Agent  pursuant  to any  provision  of this  Agreement  shall be
conclusive  and  binding  on the  Borrower  and the  Lenders  in the  absence of
manifest error. The Administrative  Agent shall, at the request of the Borrower,
deliver  to  the  Borrower  a  statement  showing  the  quotations  used  by the
Administrative  Agent in  determining  any  interest  rate  pursuant  to Section
2.16(a).

                  2.18  Inability to  Determine  Interest Rate.  If prior to the
first day of any Interest Period:

                  (a) the  Administrative  Agent  shall have  determined  (which
         determination  shall be conclusive and binding upon the Borrower) that,
         by reason of circumstances  affecting the relevant market, adequate and
         reasonable  means do not exist for ascertaining the Eurodollar Rate for
         such Interest Period, or

                  (b) the  Administrative  Agent shall have received notice from
         the Majority  Facility Lenders in respect of the relevant Facility that
         the  Eurodollar  Rate  determined or to be determined for such Interest
         Period will not  adequately and fairly reflect the cost to such Lenders
         (as  conclusively  certified by such Lenders) of making or  maintaining
         their affected Loans during such Interest Period,

the Administrative Agent shall give telecopy or telephonic notice thereof to the
Borrower and the relevant  Lenders as soon as  practicable  thereafter.  If such
notice is given (x) any Eurodollar Loans under the relevant  Facility  requested
to be made on the first day of such Interest  Period shall be made as ABR Loans,
(y) any Loans under the relevant  Facility  that were to have been  converted on
the first day of such Interest Period to Eurodollar  Loans shall be continued as
ABR Loans and (z) any outstanding  Eurodollar Loans under the relevant  Facility
shall be  converted,  on the first day of such  Interest  Period,  to ABR Loans.
Until such notice has been  withdrawn by the  Administrative  Agent,  no further
Eurodollar Loans under the relevant Facility shall be made or continued as such,
nor shall  the  Borrower  have the right to  convert  Loans  under the  relevant
Facility to Eurodollar Loans.

                  2.19 Pro Rata  Treatment and Payments.  (a) Each  borrowing by
the Borrower from the Lenders hereunder, each payment by the Borrower on account
of any commitment fee and any reduction of the  Commitments of the Lenders shall
be made pro rata  according to 



<PAGE>
                                                                              45


the  respective  Tranche  A  Term  Loan  Percentages,  Delayed  Draw  Term  Loan
Percentages,  Optional Term Loan Percentages for the relevant Optional Term Loan
Tranche or  Revolving  Credit  Percentages,  as the case may be, of the relevant
Lenders.  Each  payment  (other than  prepayments)  in respect of  principal  or
interest in respect of the Loans,  and each  payment in respect of fees  payable
hereunder  shall be applied  to the  amounts  of such  obligations  owing to the
Lenders pro rata according to the  respective  amounts then due and owing to the
Lenders.

                  (b) The amount of each principal  prepayment of the Term Loans
shall be applied to reduce the then remaining installments of the Tranche A Term
Loans,  Delayed Draw Term Loans,  Conversion Term Loans and Optional Term Loans,
as the case may be,  pro rata  based upon the then  remaining  principal  amount
thereof.  Amounts repaid on account of the Term Loans may not be reborrowed.

                  (c) Each payment  (including each  prepayment) by the Borrower
on account of principal of and interest on the  Revolving  Credit Loans shall be
made pro rata according to the respective  outstanding  principal amounts of the
Revolving Credit Loans then held by the Revolving Credit Lenders.

                  (d) All  payments  (including  prepayments)  to be made by the
Borrower  hereunder,  whether  on  account  of  principal,   interest,  fees  or
otherwise,  shall be made without setoff or counterclaim and shall be made prior
to 12:00 Noon, New York City time, on the due date thereof to the Administrative
Agent, for the account of the Lenders,  at the Payment Office, in Dollars and in
immediately  available  funds.  The  Administrative  Agent shall distribute such
payments to the Lenders promptly upon receipt in like funds as received.  If any
payment  hereunder (other than payments on the Eurodollar Loans) becomes due and
payable on a day other than a Business  Day,  such payment  shall be extended to
the next  succeeding  Business Day. If any payment on a Eurodollar  Loan becomes
due and payable on a day other than a Business  Day, the maturity  thereof shall
be  extended  to the next  succeeding  Business  Day  unless  the result of such
extension would be to extend such payment into another  calendar month, in which
event such payment shall be made on the immediately  preceding  Business Day. In
the case of any extension of any payment of principal  pursuant to the preceding
two sentences,  interest  thereon shall be payable at the then  applicable  rate
during such extension.

                  (e) Unless the  Administrative  Agent shall have been notified
in writing by any Lender prior to a borrowing that such Lender will not make the
amount  that  would  constitute  its share of such  borrowing  available  to the
Administrative  Agent, the  Administrative  Agent may assume that such Lender is
making such amount available to the Administrative Agent, and the Administrative
Agent may, in reliance upon such  assumption,  make  available to the Borrower a
corresponding amount. If such amount is not made available to the Administrative
Agent by the required time on the Borrowing Date therefor, such Lender shall pay
to the Administrative  Agent, on demand,  such amount with interest thereon at a
rate equal to the daily  average  Federal  Funds  Effective  Rate for the period
until such Lender makes such amount immediately  available to the Administrative
Agent. A certificate of the  Administrative  Agent  submitted to any Lender with
respect to any amounts  owing under this  



<PAGE>
                                                                              46


paragraph shall be conclusive in the absence of manifest error. If such Lender's
share of such  borrowing is not made  available to the  Administrative  Agent by
such  Lender  within  three   Business  Days  of  such   Borrowing   Date,   the
Administrative Agent shall also be entitled to recover such amount with interest
thereon  at the rate per  annum  applicable  to ABR  Loans  under  the  relevant
Facility, on demand, from the Borrower.

                  (f) Unless the  Administrative  Agent shall have been notified
in writing by the Borrower prior to the date of any payment being made hereunder
that the Borrower will not make such payment to the  Administrative  Agent,  the
Administrative  Agent may assume that the Borrower is making such  payment,  and
the  Administrative  Agent may, but shall not be required  to, in reliance  upon
such assumption,  make available to the Lenders their respective pro rata shares
of a  corresponding  amount.  If such payment is not made to the  Administrative
Agent by the Borrower  within three  Business  Days of such required  date,  the
Administrative  Agent shall be entitled to recover,  on demand, from each Lender
to which any amount which was made available pursuant to the preceding sentence,
such  amount  with  interest  thereon  at the rate per annum  equal to the daily
average Federal Funds  Effective  Rate.  Nothing herein shall be deemed to limit
the rights of the Administrative Agent or any Lender against the Borrower.

                  2.20 Requirements of Law. (a) If the adoption of or any change
in any  Requirement of Law or in the  interpretation  or application  thereof or
compliance  by any Lender with any request or  directive  (whether or not having
the force of law) from any central  bank or other  Governmental  Authority  made
subsequent to the date hereof:

                           (i) shall  subject  any Lender to any tax of any kind
         whatsoever  with respect to this Agreement or any Eurodollar  Loan made
         by it, or change the basis of  taxation  of  payments to such Lender in
         respect thereof (except for Non-Excluded  Taxes covered by Section 2.21
         and  changes  in the  rate of tax on the  overall  net  income  of such
         Lender);

                           (ii)  shall  impose,  modify or hold  applicable  any
         reserve,  special  deposit,  compulsory  loan  or  similar  requirement
         against  assets held by,  deposits or other  liabilities  in or for the
         account of,  advances,  loans or other  extensions of credit by, or any
         other  acquisition  of funds by, any office of such Lender which is not
         otherwise   included  in  the  determination  of  the  Eurodollar  Rate
         hereunder; or

                           (iii)    shall   impose  on  such  Lender  any  other
         condition;

and the result of any of the  foregoing  is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, converting into,
continuing or maintaining  Eurodollar  Loans, or to reduce any amount receivable
hereunder  in respect  thereof,  then,  in any such  case,  the  Borrower  shall
promptly pay such Lender,  within 30 days after its demand  (accompanied  by the
certificate  contemplated by Section 2.20(c)),  any additional amounts necessary
to compensate such Lender for such increased cost or reduced amount  receivable.
If any Lender becomes entitled to claim any additional  amounts pursuant



<PAGE>
                                                                              47

to this  Section,  it shall  promptly  notify the  Borrower  (with a copy to the
Administrative Agent) of the event by reason of which it has become so entitled.

                  (b) If any Lender shall have  determined  that the adoption of
or any change in any  Requirement  of Law regarding  capital  adequacy or in the
interpretation  or  application  thereof  or  compliance  by such  Lender or any
corporation  controlling  such Lender with any  request or  directive  regarding
capital adequacy  (whether or not having the force of law) from any Governmental
Authority  made  subsequent to the date hereof shall have the effect of reducing
the  rate  of  return  on  such  Lender's  or such  corporation's  capital  as a
consequence of its obligations hereunder to a level below that which such Lender
or such  corporation  could  have  achieved  but for such  adoption,  change  or
compliance  (taking  into  consideration  such  Lender's  or such  corporation's
policies with respect to capital adequacy) by an amount deemed by such Lender to
be  material,  then from time to time,  after  submission  by such Lender to the
Borrower (with a copy to the Administrative Agent) of a written request therefor
(accompanied by the certificate  contemplated in Section 2.20(c)),  the Borrower
shall pay to such Lender such  additional  amount or amounts as will  compensate
such Lender for such reduction.

                  (c)  A  certificate  as  to  any  additional  amounts  payable
pursuant to this  Section 2.20  submitted by any Lender to the Borrower  (with a
copy to the  Administrative  Agent)  shall set forth in  reasonable  detail  the
calculation  of such  additional  amounts  and the basis  therefor  and shall be
conclusive in the absence of manifest  error.  The  obligations  of the Borrower
pursuant to this Section shall survive the termination of this Agreement and the
payment of the Loans and all other amounts payable hereunder.

                  2.21 Taxes.  (a) All payments made by the Borrower  under this
Agreement shall be made free and clear of, and without  deduction or withholding
for or on  account  of,  any  present or future  income,  stamp or other  taxes,
levies,  imposts,  duties,  charges,  fees,  deductions or withholdings,  now or
hereafter imposed, levied,  collected,  withheld or assessed by any Governmental
Authority,  excluding net income taxes and franchise  taxes  (imposed in lieu of
net income  taxes)  imposed on any Agent or any Lender  ("Excluded  Taxes") as a
result of a present or former  connection  between such Agent or such Lender and
the  jurisdiction  of  the  Governmental  Authority  imposing  such  tax  or any
political  subdivision  or taxing  authority  thereof or therein (other than any
such connection  arising solely from such Agent or such Lender having  executed,
delivered or performed its obligations or received a payment under, or enforced,
this  Agreement or any other Loan  Document).  If any such  non-excluded  taxes,
levies,   imposts,   duties,   charges,   fees,   deductions   or   withholdings
("Non-Excluded  Taxes") or Other  Taxes are  required  to be  withheld  from any
amounts payable to any Agent or any Lender hereunder,  the amounts so payable to
such Agent or such Lender shall be increased to the extent necessary to yield to
such Agent or such Lender  (after  payment of all  Non-Excluded  Taxes and Other
Taxes) interest or any such other amounts  payable  hereunder at the rates or in
the amounts specified in this Agreement,  provided,  however,  that the Borrower
shall not be required to increase  any such  amounts  payable to any Lender with
respect to any  Non-Excluded  Taxes or Other Taxes (i) that are  attributable to
such Lender's failure to comply with the requirements of paragraph (d) or (e) of
this Section or (ii) that are United States withholding taxes imposed on amounts
payable to such Lender at the time the Lender 



<PAGE>
                                                                              48

becomes a party to this  Agreement,  except  to the  extent  that such  Lender's
assignor (if any) was in compliance  with the  requirements of this Section 2.21
and entitled, at the time of assignment,  to receive additional amounts from the
Borrower with respect to such Non-Excluded Taxes pursuant to Section 2.21(a).

                  (b) In addition, the Borrower shall pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable law.

                  (c) Whenever any Non-Excluded Taxes or Other Taxes are payable
by the Borrower,  as promptly as possible  thereafter the Borrower shall send to
the Administrative Agent for the account of the relevant Agent or Lender, as the
case may be, a certified copy of an original  official  receipt  received by the
Borrower showing payment thereof.  If the Borrower fails to pay any Non-Excluded
Taxes or Other Taxes when due to the  appropriate  taxing  authority or fails to
remit  to the  Agents  the  required  receipts  or  other  required  documentary
evidence,  the Borrower shall indemnify the Administrative Agent and the Lenders
for any incremental taxes,  interest or penalties that may become payable by any
Agent or any  Lender as a result of any such  failure.  The  agreements  in this
Section 2.21 shall survive the  termination of this Agreement and the payment of
the Loans and all other amounts payable hereunder.

                  (d) Each  Lender  (or  Transferee)  that is not a  citizen  or
resident of the United States of America,  a  corporation,  partnership or other
entity created or organized in or under the laws of the United States of America
(or any jurisdiction thereof), or any estate or trust that is subject to federal
income  taxation  regardless  of the source of its income (a "Non-U.S.  Lender")
shall deliver to the Borrower and the Administrative Agent (or, in the case of a
Participant,  to the Lender from which the related participation shall have been
purchased) (i) two copies of either U.S.  Internal  Revenue Service Form 1001 or
Form 4224,  or, in the case of a Non-U.S.  Lender  claiming  exemption from U.S.
federal  withholding tax under Section 871(h) or 881(c) of the Code with respect
to payments of  "portfolio  interest" a statement  substantially  in the form of
Exhibit I and a Form W-8,  or any  subsequent  versions  thereof  or  successors
thereto  properly  completed and duly executed by such Non-U.S.  Lender claiming
complete  exemption from, or a reduced rate of, U.S. federal  withholding tax on
all payments by the Borrower under this Agreement and the other Loan  Documents,
and  (ii) a  certificate  (A) in the  case of a Form  1001 or  4224,  that  such
Non-U.S.  Lender is entitled to receive  payments under this  Agreement  without
deduction or  withholding  of any United States  federal income taxes and (B) in
the case of a Form W-8,  that such  Non-U.S.  Lender is entitled to an exemption
from United States  withholding tax. Such forms,  statements and  certifications
shall be  delivered by each  Non-U.S.  Lender on or before the date it becomes a
party to this  Agreement (or, in the case of any  Participant,  on or before the
date such Participant purchases the related  participation).  Each Non-US Lender
shall  obtain  any  extensions  of time for filing and  completing  such  forms,
statements or certifications as may be reasonably requested by the Borrower.  In
addition,  each  Non-U.S.  Lender  shall  deliver  such  forms,  statements  and
certifications  promptly upon the expiration,  obsolescence or invalidity of any
forms,  statements  and  certifications  previously  delivered by such  Non-U.S.
Lender.  Each Non-U.S.  Lender shall promptly notify the Borrower at any time it
determines  that  it is no  longer  in a  position  to  provide  any  previously
delivered   form  or   certificate  to  the  



<PAGE>
                                                                              49

Borrower  (or any  other  form  of  certification  adopted  by the  U.S.  taxing
authorities  for such  purpose).  Notwithstanding  any other  provision  of this
paragraph, a Non-U.S.  Lender shall not be required to deliver any form pursuant
to this paragraph that such Non-U.S. Lender is not legally able to deliver.

                  (e) A  Lender  that  is  entitled  to  an  exemption  from  or
reduction of non-U.S. withholding tax under the law of the jurisdiction in which
the Borrower is located,  or any treaty to which such  jurisdiction  is a party,
with  respect to payments  under this  Agreement  shall  deliver to the Borrower
(with a copy to the  Administrative  Agent),  at the time or times prescribed by
applicable law or reasonably requested by the Borrower,  such properly completed
and executed  documentation  prescribed  by  applicable  law as will permit such
payments to be made without withholding or at a reduced rate, provided that such
Lender is legally entitled to complete,  execute and deliver such  documentation
and  in  such  Lender's  reasonable  judgment  such  completion,   execution  or
submission would not materially prejudice the legal position of such Lender.

                  2.22  Indemnity.  The Borrower agrees to indemnify each Lender
and to hold each Lender  harmless from any loss or expense (but  excluding  lost
profits)  which such Lender has  sustained or incurred as a  consequence  of (a)
default  by  the  Borrower  in  making  a  borrowing  of,   conversion  into  or
continuation  of  Eurodollar  Loans  after  the  Borrower  has  given  a  notice
requesting  the same in accordance  with the provisions of this  Agreement,  (b)
default by the Borrower in making any  prepayment of Eurodollar  Loans after the
Borrower has given a notice  thereof in accordance  with the  provisions of this
Agreement or (c) the making of a prepayment of  Eurodollar  Loans on a day which
is  not  the  last  day  of  an  Interest  Period  with  respect  thereto.  Such
indemnification  may include an amount  equal to the excess,  if any, of (i) the
amount of interest which would have accrued on the amount so prepaid,  or not so
borrowed,  converted  or  continued,  for  the  period  from  the  date  of such
prepayment or of such failure to borrow,  convert or continue to the last day of
such  Interest  Period  (or,  in the case of a failure  to  borrow,  convert  or
continue,  the  Interest  Period that would have  commenced  on the date of such
failure)  in each case at the  applicable  Eurodollar  Rate for such  Eurodollar
Loans provided for herein (excluding,  however, the Applicable Margin) over (ii)
the amount of interest (as  reasonably  determined  by such Lender)  which would
have accrued to such Lender on such amount by placing such amount on deposit for
a comparable  period with leading banks in the interbank  eurodollar  market.  A
certificate as to any amounts payable pursuant to this Section  submitted to the
Borrower  by any Lender  shall set forth in  reasonable  detail the  calculation
thereof  and the  basis  therefor  and shall be  conclusive  in the  absence  of
manifest  error.  This covenant shall survive the  termination of this Agreement
and the payment of the Loans and all other amounts payable hereunder.

                  2.23 Illegality.  Notwithstanding  any other provision herein,
if  the  adoption  of or  any  change  in  any  Requirement  of  Law  or in  the
interpretation  or application  thereof shall make it unlawful for any Lender to
make or maintain Eurodollar Loans as contemplated by this Agreement, such Lender
shall give prompt notice  thereof to the Borrower and the  Administrative  Agent
and thereafter (a) the  commitment of such Lender  hereunder to make  Eurodollar
Loans,  continue  Eurodollar  Loans as such and convert ABR Loans to  Eurodollar
Loans shall forthwith be cancelled and (b) such Lender's Loans then  outstanding
as 



<PAGE>
                                                                              50


Eurodollar  Loans, if any, shall be converted  automatically to ABR Loans on the
respective last days of the then current  Interest  Periods with respect to such
Loans or within such earlier  period as required by law. If any such  conversion
of a  Eurodollar  Loan  occurs  on a day  which  is not the last day of the then
current  Interest  Period with respect  thereto,  the Borrower shall pay to such
Lender such amounts, if any, as may be required pursuant to Section 2.22.

                  2.24 Change of Lending  Office.  Each Lender agrees that, upon
the  occurrence  of any event  giving  rise to the  operation  of Section  2.20,
2.21(a) or 2.23 with  respect  to such  Lender,  it will,  if  requested  by the
Borrower or if it makes any demand for compensation under any such Section,  use
reasonable efforts to designate another lending office for any Loans affected by
such event with the object of avoiding the consequences of such event; provided,
that  such  designation  is made on terms  that,  in the sole  judgment  of such
Lender, cause such Lender and its lending office(s) to suffer no economic, legal
or regulatory disadvantage,  and provided, further, that nothing in this Section
shall affect or postpone any of the obligations of any Borrower or the rights of
any Lender pursuant to Section 2.20, 2.21(a) or 2.23.

                    SECTION 3. REPRESENTATIONS AND WARRANTIES

                  To  induce  the  Agents  and the  Lenders  to enter  into this
Agreement and to make the Loans, the Borrower hereby  represents and warrants to
each Agent and each Lender that:

                  3.1  Financial  Condition.  The audited  consolidated  balance
sheet of the  Borrower  as at December  31,  1997 and the  related  consolidated
statements  of income and of cash flows for the fiscal  year ended on such date,
as set forth in the  Borrower's  annual report on Form 10-K,  reported on by and
accompanied by an unqualified report from Ernst & Young LLP, presents fairly the
consolidated  financial  condition  of the  Borrower  as at such  date,  and the
consolidated  results of its operations and its consolidated  cash flows for the
fiscal year then ended. The unaudited  consolidated  condensed  balance sheet of
the  Borrower  as at March 31,  1998,  and the  related  unaudited  consolidated
condensed  statements of income and cash flows for the three-month  period ended
on such  date,  as set forth in the  Borrower's  quarterly  report on Form 10-Q,
present fairly the consolidated  financial  condition of the Borrower as at such
date, and the consolidated  results of its operations and its consolidated  cash
flows for the  three-month  period then ended (subject to normal  year-end audit
adjustments). All such financial statements, including the related schedules and
notes thereto,  have been prepared in accordance with GAAP applied  consistently
throughout the periods involved (except as approved by the  aforementioned  firm
of accountants or a Responsible Officer and disclosed therein). The Borrower and
its  Subsidiaries  do not have any material  Guarantee  Obligations,  contingent
liabilities  and  liabilities  for  taxes,  or any  long-term  leases or unusual
forward or long-term commitments,  including,  without limitation,  any interest
rate or foreign  currency swap or exchange  transaction  or other  obligation in
respect of  derivatives,  which are not  reflected in the most recent  financial
statements  referred to in this  paragraph.  During the period from December 31,
1997 to and  including  the date  hereof  there has been no  Disposition  by the
Borrower of any material part of its business or Property.

                                                                              51

                  3.2 No  Change.  Since  December  31,  1997  there has been no
development  or event  which has had or could  reasonably  be expected to have a
Material Adverse Effect.

                  3.3  Corporate  Existence;  Compliance  with Law.  Each of the
Borrower and its  Subsidiaries  (a) is duly organized,  validly  existing and in
good standing under the laws of the  jurisdiction of its  organization,  (b) has
the corporate  power and authority,  and the legal right, to own and operate its
Property,  to lease the  Property  it  operates  as lessee  and to  conduct  the
business in which it is currently  engaged,  (c) is duly  qualified as a foreign
corporation and in good standing under the laws of each  jurisdiction  where its
ownership,  lease or  operation  of  Property  or the  conduct  of its  business
requires such  qualification  and (d) is in compliance with all  Requirements of
Law, in each case described in the foregoing  clauses (c) and (d), except to the
extent that the failure to be so qualified  and in good  standing,  or to comply
therewith could not, in the aggregate, reasonably be expected to have a Material
Adverse Effect.

                  3.4 Corporate Power;  Authorization;  Enforceable Obligations.
Each Loan Party has the corporate  power and authority,  and the legal right, to
make,  deliver and perform the Loan Documents to which it is a party and, in the
case of the  Borrower,  to  borrow  hereunder.  Each  Loan  Party  has taken all
necessary corporate action to authorize the execution,  delivery and performance
of the Loan  Documents to which it is a party and, in the case of the  Borrower,
to authorize the  borrowings on the terms and conditions of this  Agreement.  No
consent  or  authorization  of,  filing  with,  notice  to or other act by or in
respect  of, any  Governmental  Authority  or any other  Person is  required  in
connection  with  the  borrowings  hereunder  or with the  execution,  delivery,
performance,  validity or  enforceability  of this  Agreement or any of the Loan
Documents, except (i) consents, authorizations, filings and notices described in
Schedule 3.4, which consents,  authorizations,  filings and notices have, in all
material  respects,  been  obtained  or made and are in full force and effect or
waived,  (ii) the filings  referred to in Section 3.19 and (iii) state consents,
authorizations,  filings, and notices which have, in all material respects, been
obtained or made and are in full force and effect.  Each Loan  Document has been
duly  executed  and  delivered  on behalf of each  Loan  Party  which is a party
thereto. This Agreement constitutes, and each other Loan Document upon execution
will constitute,  a legal, valid and binding obligation of each Loan Party which
is a party thereto,  enforceable against each such Loan Party in accordance with
its terms,  except as  enforceability  may be limited by applicable  bankruptcy,
insolvency, reorganization, moratorium or similar laws affecting the enforcement
of creditors'  rights  generally and by general  equitable  principles  (whether
enforcement is sought by proceedings in equity or at law).

                  3.5 No Legal Bar. The execution,  delivery and  performance of
this Agreement and the other Loan  Documents,  the borrowings  hereunder and the
use of the  proceeds  thereof  will not  violate any  Requirement  of Law or any
Contractual  Obligation of the Borrower or any of its  Subsidiaries and will not
result in, or require,  the creation or  imposition  of any Lien on any of their
respective properties or revenues pursuant to any Requirement of Law or any such
Contractual  Obligation  (other  than the Liens  created by or  pursuant  to the
Security  Documents and Liens  permitted by Section  6.3),  except to the extent

                                                                              52


that any such violations (individually or in the aggregate) could not reasonably
be expected to have a Material Adverse Effect.

                  3.6 No Material  Litigation.  No litigation,  investigation or
proceeding of or before any arbitrator or Governmental  Authority is pending or,
to the knowledge of the  Borrower,  threatened by or against the Borrower or any
of its  Subsidiaries or against any of their  respective  properties or revenues
(a)  with  respect  to any  of the  Loan  Documents  or any of the  transactions
contemplated  hereby or thereby,  or (b) which could  reasonably  be expected to
have a Material  Adverse  Effect.  Set forth on Schedule 3.6 is a description of
certain  litigation  which could not  reasonably  be expected to have a Material
Adverse Effect.

                  3.7  No  Default.   Neither  the   Borrower  nor  any  of  its
Subsidiaries  is in  default  under or with  respect  to any of its  Contractual
Obligations in any respect which could reasonably be expected to have a Material
Adverse Effect. No Default or Event of Default has occurred and is continuing.

                  3.8 Ownership of Property; Liens. Each of the Borrower and its
Restricted  Subsidiaries  has  title  in fee  simple  to,  or a valid  leasehold
interest  in, all its real  property,  and good  title to, or a valid  leasehold
interest  in, all its other  Property,  except to the extent that the failure to
have  such  title or  interest  (individually  or in the  aggregate)  could  not
reasonably  be  expected  to have a Material  Adverse  Effect,  and none of such
Property is subject to any Lien except as permitted by Section 6.3.

                  3.9  Intellectual  Property.  The  Borrower  and  each  of its
Restricted  Subsidiaries owns, or is licensed to use, all Intellectual  Property
necessary  for the conduct of its  business as currently  conducted,  except for
those which the failure to own or license  could not  reasonably  be expected to
have a Material  Adverse  Effect.  No material  claim has been  asserted  and is
pending by any Person  challenging  or questioning  the use of any  Intellectual
Property or the validity or  effectiveness  of any  Intellectual  Property  that
could  reasonably be expected to have a Material  Adverse  Effect,  nor does the
Borrower  know of any valid  basis for any such claim.  The use of  Intellectual
Property by the Borrower and its  Restricted  Subsidiaries  does not infringe on
the rights of any Person, except for infringements that, in the aggregate, could
not reasonably be expected to have a Material Adverse Effect.

                  3.10 Taxes.  Each of the Borrower and each of its Subsidiaries
has  filed or  caused to be filed all  Federal,  state  and other  material  tax
returns  which are  required  to be filed and has paid all taxes shown to be due
and payable on said returns or on any assessments  made against it or any of its
Property and all other taxes,  fees or other charges imposed on it or any of its
Property by any Governmental Authority (other than any such tax returns,  taxes,
fees or other  charges (i) the amount or validity of which are  currently  being
contested  in good faith by  appropriate  proceedings  and with respect to which
reserves in conformity with GAAP have been provided on the books of the Borrower
or its  Subsidiaries,  as the  case may be or (ii)  which if not  filed or paid,
could not reasonably be expected to have a Material Adverse Effect); no tax Lien
has  been  filed,  and,  to the  knowledge  of the  Borrower,  no claim is being
asserted,  with respect to any such tax,  fee or other  charge  (other than with
respect to any such tax,  fee or other charge the amount or validity of which is
then

                                                                              53


being  contested in good faith by  appropriate  proceedings  and with respect to
which  reserves in  conformity  with GAAP have been provided on the books of the
Borrower or its Subsidiaries, as the case may be, and which could not reasonably
be expected to have a Material Adverse Effect).

                  3.11 Federal Regulations. No part of the proceeds of any Loans
will be used for  "purchasing"  or  "carrying"  any  "margin  stock"  within the
respective  meanings of each of the quoted  terms under  Regulation U as now and
from time to time  hereafter  in effect or for any purpose  which  violates  the
provisions of the  Regulations  of the Board.  If requested by any Lender or the
Administrative  Agent, the Borrower will furnish to the Administrative Agent and
each  Lender  a  statement  to the  foregoing  effect  in  conformity  with  the
requirements of FR Form G-3 or FR Form U-1 referred to in Regulation U.

                  3.12 ERISA.  Neither a  Reportable  Event nor an  "accumulated
funding  deficiency"  (within  the meaning of Section 412 of the Code or Section
302 of ERISA) has  occurred  during the  five-year  period  prior to the date on
which this  representation  is made or deemed made with respect to any Plan, and
each Plan has complied in all material  respects with the applicable  provisions
of ERISA  and the  Code,  except  where the  failure  to so comply  could not be
reasonably  expected to have a Material  Adverse  Effect.  No  termination  of a
Single  Employer  Plan has  occurred  except  where such  termination  could not
reasonably be expected to have a Material  Adverse Effect,  and no Lien in favor
of the PBGC or a Plan has arisen,  during  such  five-year  period.  The present
value of all accrued  benefits  under each Single  Employer Plan (based on those
assumptions  used to fund such Plans) did not,  as of the last annual  valuation
date  prior to the date on which  this  representation  is made or deemed  made,
exceed the value of the assets of such Plan  allocable to such accrued  benefits
by a  material  amount,  except to the  extent  that any such  excess  could not
reasonably be expected to have a Material  Adverse Effect.  Neither the Borrower
nor any Commonly Controlled Entity has had a complete or partial withdrawal from
any  Multiemployer  Plan which has resulted or could  reasonably  be expected to
result in a material  liability  under  ERISA,  and neither the Borrower nor any
Commonly  Controlled Entity would become subject to any material liability under
ERISA if the Borrower or any such  Commonly  Controlled  Entity were to withdraw
completely  from all  Multiemployer  Plans as of the valuation date most closely
preceding the date on which this  representation is made or deemed made, in each
case,  except where such  liability  could not  reasonably be expected to have a
Material Adverse Effect.  No such  Multiemployer  Plan is in  Reorganization  or
Insolvent.

                  3.13 Investment Company Act; Other Regulations.  No Loan Party
is  an  "investment  company",  or a  company  "controlled"  by  an  "investment
company",  within the meaning of the Investment Company Act of 1940, as amended.
No Loan Party is subject to regulation  under any Requirement of Law (other than
Regulation X of the Board) which limits its ability to incur Indebtedness.

                  3.14  Subsidiaries.  The Subsidiaries  listed on Schedule 3.14
constitute all the Subsidiaries of the Borrower at the date hereof.

                                                                              54


                  3.15 Use of  Proceeds.  The  proceeds  of the  Tranche  A Term
Loans,  the  Revolving  Credit  Loans,  the  Delayed  Draw  Term  Loans  and the
Conversion Term Loans will be used to finance capital  expenditures,  including,
but not  limited  to,  the  purchase  of  equipment  under the  Nortel  Purchase
Agreement,  and for working capital and other general corporate  purposes of the
Borrower and its  Subsidiaries;  provided,  that  $20,000,000 of the proceeds of
such Loans,  and 100% of the proceeds of the Optional Term Loans,  shall be used
solely to finance the  acquisition,  construction,  expansion or  development of
Telecommunications    Assets    such   that   such   Loans    will    constitute
Telecommunications  Assets  Debt within the meaning of Section 101 of the Senior
Discount Note Indenture.

                  3.16  Absence  of  Material  Obligations.  None of  LeasingCo,
LicenseCo or AssetCo has any material  obligations or liabilities  other than in
connection  with (a) the Guarantee and  Collateral  Agreement and the other Loan
Documents to which it is a party, (b) in the case of LicenseCo,  its obligations
to comply with the  requirements  of the FCC Licenses held by it, and (c) in the
case of each of LeasingCo  and AssetCo,  any lease or license in respect of real
or personal property which LeasingCo or AssetCo, as the case may be, has entered
into or assumed in the  ordinary  course of business and other  obligations  and
liabilities  incurred in the ordinary  course of business  which are incident to
being the owner, lessee or licensee of real or personal property.

                  3.17  Environmental  Matters.  Except to the  extent  that the
failure of the  following  statements  to be true could not,  in the  aggregate,
reasonably be expected to have a Material Adverse Effect:

                  (a) The facilities and properties,  or portion thereof,  owned
by the Borrower or any of its  Subsidiaries,  and to the  Borrower's  knowledge,
those leased by the  Borrower and its  Subsidiaries  (the  "Properties")  do not
contain,  and have not  previously  contained,  any  Materials of  Environmental
Concern in amounts or concentrations or under circumstances which (i) constitute
or constituted a violation by the Borrower or any of its  Subsidiaries,  or (ii)
could give rise to liability for the Borrower or any of its  Subsidiaries  under
any Environmental Law.

                  (b) The Properties owned by the Borrower and its Subsidiaries,
and  to  the  Borrower's   knowledge  those  leased  by  the  Borrower  and  its
Subsidiaries,  and all operations of the Borrower or any of its  Subsidiaries at
the Properties are in material compliance,  and have in the last five years been
in material compliance,  with all applicable Environmental Laws, and there is no
contamination   at,  under  or  about  the   Properties   or  violation  of  any
Environmental Law with respect to the Properties or the business operated by the
Borrower or any of its  Subsidiaries  (the  "Business")  which could  materially
interfere with the continued  operation of the Properties.  Neither the Borrower
nor any of its  Subsidiaries has assumed any liability of any other Person under
Environmental Laws.

                  (c)  Neither  the  Borrower  nor any of its  Subsidiaries  has
received  or  is  aware  of  any  notice  of   violation,   alleged   violation,
non-compliance, liability or potential liability regarding environmental matters
or compliance  with  Environmental  Laws with regard to any 



<PAGE>
                                                                              55


of the  Properties  or the  Business,  nor does the Borrower  have  knowledge or
reason to believe that any such notice will be received or is being threatened.

                  (d)   Materials  of   Environmental   Concern  have  not  been
transported  or disposed of from the  Properties in violation of, or in a manner
or to a location  which could give rise to liability  under,  any  Environmental
Law, nor have any Materials of  Environmental  Concern been generated,  treated,
stored or disposed of at, on or under any of the  Properties in violation of, or
in  a  manner  that  could  give  rise  to  liability   under,   any  applicable
Environmental Law.

                  (e) No judicial  proceeding or governmental or  administrative
action is pending or, to the  knowledge of the Borrower,  threatened,  under any
Environmental Law to which the Borrower or any Subsidiary is or could reasonably
be  expected  to be named  as a party  with  respect  to the  Properties  or the
Business,  nor are there any consent  decrees or other decrees,  consent orders,
administrative  orders or other  orders,  or other  administrative  or  judicial
requirements  outstanding  under  any  Environmental  Law  with  respect  to the
Properties or the Business.

                  (f)  There  has  been no  release  or  threat  of  release  of
Materials of Environmental Concern at or from the Properties, or arising from or
related to the operations of the Borrower or any  Subsidiary in connection  with
the Properties or otherwise in connection with the Business,  in violation of or
in amounts or in a manner that could give rise to liability under  Environmental
Laws.

                  3.18 Accuracy of Information, etc. No statement or information
(other than estimates and  projections)  contained in this Agreement,  any other
Loan Document,  the Confidential  Information  Memorandum or any other document,
certificate or written statement  furnished to the  Administrative  Agent or the
Lenders or any of them, by or on behalf (with the consent,  or at the direction,
of the Borrower) of any Loan Party for use in connection  with the  transactions
contemplated by this Agreement or the other Loan Documents,  contained as of the
date such statement,  information, document or certificate was so furnished (or,
in the case of the Confidential  Information Memorandum,  as of the date of this
Agreement),  any  untrue  statement  of a  material  fact or  omitted to state a
material  fact  necessary in order to make the  statements  contained  herein or
therein not materially misleading in light of the circumstances under which such
statements  were  made.  The  projections  and pro forma  financial  information
contained in the materials  referenced above are based upon good faith estimates
and  assumptions  believed by management of the Borrower to be reasonable at the
time made, it being recognized by the Lenders that such financial information as
it relates to future events is not to be viewed as fact and that actual  results
during the period or periods  covered by such financial  information  may differ
from the projected  results set forth therein by a material amount.  There is no
fact  known to any Loan  Party  that  could  reasonably  be  expected  to have a
Material  Adverse Effect that has not been expressly  disclosed  herein,  in the
other Loan Documents, in the Confidential Information Memorandum or in any other
documents, certificates and statements furnished to the Administrative Agent and
the Lenders for use in connection with the transactions  contemplated hereby and
by the other Loan Documents. To the extent that the foregoing representation and
warranty relates to the

                                                                              56

Confidential  Information Memorandum,  it is limited as set forth in the letter,
dated May 14, 1998, from the Borrower to the Chase Securities Inc.  contained in
the Confidential Information Memorandum.

                  3.19  Security   Documents.   The  Guarantee  and   Collateral
Agreement is effective to create in favor of the Collateral Agent a legal, valid
and  enforceable  security  interest  in the  Collateral  described  therein and
proceeds  thereof.  In the case of the Pledged Stock  described in the Guarantee
and Collateral  Agreement,  when stock  certificates  representing  such Pledged
Stock  are  delivered  to the  Collateral  Agent,  and in the case of the  other
Collateral  constituting  Direct-Lien  Assets  described  in the  Guarantee  and
Collateral Agreement, when financing statements in appropriate form are filed in
the  offices  specified  on  Schedule  3.19(a),  the  Guarantee  and  Collateral
Agreement  shall,  subject to Section 3.2 thereof,  constitute a fully perfected
Lien on, and  security  interest  in, all right,  title and interest of the Loan
Parties  in such  Collateral  and the  proceeds  thereof,  as  security  for the
Obligations (as defined in the Guarantee and Collateral Agreement), in each case
prior and superior in right to any other Person.

                  3.20 Solvency. Assuming that the provisions of Sections 2.1(b)
and 2.2 of the Guarantee and Collateral  Agreement are effective and satisfy the
requirements  of applicable  laws, as of the Closing Date,  the Borrower and its
Subsidiaries  after giving effect to the incurrence of the  Indebtedness  of the
Tranche A Term Loans and the Revolving  Credit Loans (assuming full  utilization
of such Loans), will be Solvent.

                  3.21 FCC and State Regulatory Compliance. (a) The Borrower and
LicenseCo  are in  compliance  with the  Communications  Act and all  applicable
communications laws and regulations of the States identified on Schedule 3.21(c)
(collectively,  "States"),  except  to the  extent  that  the  failure  to be in
compliance could not reasonably be expected to have a Material Adverse Effect.

                  (b) The  Borrower and its  Subsidiaries  hold the FCC Licenses
identified in Schedule  4.1(f).  Except as described in Schedule  3.21,  each of
such  FCC  Licenses  is in full  force  and  effect  and has not  been  revoked,
suspended,  canceled,  or modified in any adverse way and,  except as may be set
forth on Schedule 4.1(f),  is not subject to any conditions or requirements that
are not generally imposed by the FCC upon the holders of such licenses.  The FCC
Licenses  listed in Schedule  4.1(f) are the only FCC Licenses  required for the
conduct of the business of the Borrower as presently conducted.

                  (c)  The  Borrower  and its  Subsidiaries  have  all  permits,
certificates,  licenses, tariff approvals and other authorizations (collectively
"State  Permits") from the States required (i) to conduct its current  business;
and (ii) except as  identified  in Schedule  3.21(c),  to conduct  business as a
competitive local exchange carrier, long distance service provider, and Internet
access provider as identified in such Schedule.

                  (d) Except as described on Schedule 3.21, (i) the Borrower has
no  knowledge of any  investigation,  notice of apparent  liability,  violation,
forfeiture  or other  order or  complaint  issued  by or  before  the FCC or the
States,  or of any other  proceedings  (other than  



<PAGE>
                                                                              57

proceedings relating to the wireless communications  industries generally) of or
before the FCC or the  States,  which  could  reasonably  be  expected to have a
Material  Adverse  Effect;  and  (ii) no  proceedings  are  pending  or,  to the
knowledge  of the  Borrower,  threatened,  to revoke or limit any FCC License or
State Permit,  except,  in each case, those the absence or violation of which do
not and could not reasonably be expected to have a Material Adverse Effect.

                  (e) Except as described on Schedule  3.21, the Borrower has no
knowledge of the  occurrence  of any event which (i) results in, or after notice
or  lapse of time or both  would  result  in,  revocation,  suspension,  adverse
modifications,  non-renewal, impairment, restriction or termination of, or order
of  forfeiture  with  respect to, any State Permit or FCC License in any respect
that could  reasonably be expected to have a Material  Adverse  Effect,  or (ii)
affects  or could  reasonably  be  expected  in the  future to affect any of the
rights of the Borrower or LicenseCo under any State Permit or FCC License in any
respect that could reasonably be expected to have a Material Adverse Effect.

                  (f) Each of the  Borrower  and  LicenseCo  has duly filed in a
timely  manner  all  material   filings,   reports,   applications,   documents,
instruments and information  required to be filed by it under the Communications
Act and all applicable State  communications laws and regulations,  and all such
filings  were when made true,  correct and  complete in all  material  respects,
except to the extent  that the  failure  to comply or the  failure of any of the
statements made in this paragraph to be true and correct could not reasonably be
expected to have a Material Adverse Effect.

                  3.22  Collateral.  To the extent permitted by law and required
by Section 5.10 with respect to  after-acquired  assets,  the  Collateral  Agent
holds  pursuant to the  Security  Documents  a legal,  valid,  enforceable  and,
subject  to the  provisions  of  Section  3.2 of the  Guarantee  and  Collateral
Agreement, fully perfected Lien on all right, title and interest of the Borrower
and each Restricted Subsidiary in any asset (other than Excluded Assets) and the
proceeds  thereof,  and none of such assets is subject to any other Lien (except
for Liens  permitted  by Section  6.3).  None of the assets  held by any Special
Purpose  Subsidiary  is subject to any Lien  other  than Liens  permitted  under
subsections 6.3(a), (b), (d), (e), (h), (i) or (k).

                  3.23 Year 2000.  The  Borrower has no reason to believe that a
Material  Adverse  Effect  will  occur as a result of the  failure  of  computer
hardware or software  used in the business or operations of the Borrower and its
Subsidiaries  to  function  in  the  receipt,   processing,   storage  or  other
utilization  of data in the  case of  dates  or  time  periods  occurring  after
December  31,  1999 at  least  as  effectively  as in the  case of dates or time
periods occurring prior to January 1, 2000. Any reprogramming required to permit
the  proper  functioning,  in and  following  the year 2000,  of the  Borrower's
computer  hardware and software is  reasonably  expected to be completed by June
30,  1999,  except to the  extent  that the  Borrower  has  given  notice to the
Administrative Agent that such reprogramming will not be completed by such date.
The cost to the Borrower of such reprogramming  could not reasonably be expected
to have a Material Adverse Effect.

         available.

                  (e)  Structure.  Any material  change in the capital,  tax and

reason of (i) any  restrictions  existing  under the Loan Documents and (ii) any
restrictions  with respect to a  Restricted  Subsidiary  imposed  pursuant to an

         the expiration of all grace and cure periods applicable  thereto,  such
         Indebtedness to become due prior to its stated maturity or (in the case
         of any such Indebtedness constituting a Guarantee Obligation) to become
         payable;  provided,  that a default,  event or  condition  described in
         clause  (i) or  (ii)  of  this  paragraph  (e)  shall  not at any  time

         in the entry of an order for any such relief  which shall not have been

         Subsidiaries shall take any action in furtherance of, or indicating its

         Code) involving any Plan, (ii) any "accumulated funding deficiency" (as
         defined in Section 302 of ERISA),  whether or not  waived,  shall exist
         with  respect  to any  Plan or any  Lien in favor of the PBGC or a Plan

         of Title IV of ERISA, (iv) any Single Employer Plan shall terminate for
         purposes  of  Title  IV of  ERISA,  (v) the  Borrower  or any  Commonly
         Controlled  Entity shall, or in the reasonable  opinion of the Required
         Lenders  is  likely  to,  incur  any  liability  in  connection  with a
         withdrawal   from,   or  the   Insolvency  or   Reorganization   of,  a
         Multiemployer  Plan or (vi) any other event or condition shall occur or
         exist with  respect to a Plan;  and in each case in clauses (i) through

         events or conditions,  if any,  could  reasonably be expected to have a
         Material Adverse Effect; or

                  (h) One or more judgments or decrees shall be entered  against
         the  Borrower or any of its  Restricted  Subsidiaries  involving in the

                              SECTION 8. THE AGENTS

                  8.1 Appointment. Each Lender hereby irrevocably designates and
appoints  the Agents as the agents of such Lender under this  Agreement  and the
other Loan Documents, and each such Lender irrevocably authorizes each Agent, in
such  capacity,  to take such action on its behalf under the  provisions of this
Agreement  and the other Loan  Documents and to exercise such powers and perform
such duties as are  expressly  delegated  to the such Agent by the terms of this
Agreement and the other Loan  Documents,  together with such other powers as are
reasonably  incidental  thereto.  Notwithstanding  any provision to the contrary
elsewhere in this Agreement, no Agent shall have any duties or responsibilities,
except those expressly set forth herein, or any fiduciary  relationship with any
Lender,  and  no  implied  covenants,   functions,   responsibilities,   duties,
obligations or  liabilities  shall be read into this Agreement or any other Loan
Document or otherwise exist against any Agent.

                  8.2  Delegation  of Duties.  Each Agent may execute any of its
duties under this Agreement and the other Loan Documents by or through agents or
attorneys-in-fact  and shall be  entitled  to advice of counsel  concerning  all
matters  pertaining  to such  duties.  No  Agent  shall be  responsible  for the
negligence or misconduct of any agents or attorneys  in-fact selected by it with
reasonable care.

                  8.3 Exculpatory Provisions.  Neither any of the Agents nor any
of their respective officers, directors, employees, agents, attorneys-in-fact or
affiliates  shall be (i) liable for any action  lawfully  taken or omitted to be
taken by it or such Person  under or in  connection  with this  Agreement or any
other Loan  Document  (except to the extent that any of the  foregoing  resulted
from its or such Person's own gross  negligence or willful  misconduct)  or (ii)
responsible  in any manner to any of the Lenders for any  recitals,  statements,
representations  or  warranties  made by any Loan Party or any  officer  thereof
contained in this  Agreement or any other Loan  Document or in any  certificate,
report,  statement or other document referred to or provided for in, or received
by the Agents  under or in  connection  with,  this  Agreement or any other Loan
Document or for the value, validity, effectiveness,  genuineness, enforceability
or  sufficiency  of this Agreement or any other Loan Document or for any failure
of any Loan Party a party  thereto  to  perform  its  obligations  hereunder  or
thereunder.  The  Agents  shall not be under  any  obligation  to any  Lender to
ascertain  or to  inquire  as to the  observance  or  performance  of any of the
agreements  contained  in, or  conditions  of, this  Agreement or any other Loan
Document, or to inspect the properties, books or records of any Loan Party.

                  8.4 Reliance by Agents.  Each Agent shall be entitled to rely,
and  shall  be  fully  protected  in  relying,  upon  any  instrument,  writing,
resolution, notice, consent, certificate,  affidavit, letter, telecopy, telex or
teletype message, statement, order or other document or conversation believed by
it to be genuine and correct and to have been signed, sent or made by the proper
Person or Persons and upon advice and  statements of legal  counsel  (including,
without limitation,  counsel to the Loan Parties),  independent  accountants and
other  experts  selected by the  Administrative  Agent.  The Agents may deem and
treat the  payee of any Note 



<PAGE>
                                                                              81


as the owner  thereof for all purposes  unless a written  notice of  assignment,
negotiation  or transfer  thereof shall have been filed with the  Administrative
Agent.  Each Agent shall be fully  justified  in failing or refusing to take any
action  under this  Agreement or any other Loan  Document  unless it shall first
receive such advice or concurrence of the Required  Lenders (or, if so specified
by this  Agreement,  all Lenders) as it deems  appropriate  or it shall first be
indemnified to its satisfaction by the Lenders against any and all liability and
expense  which may be incurred by it by reason of taking or  continuing  to take
any such action.  Each Agent shall in all cases be fully protected in acting, or
in refraining from acting,  under this Agreement and the other Loan Documents in
accordance  with a request of the Required  Lenders (or, if so specified by this
Agreement, all Lenders), and such request and any action taken or failure to act
pursuant thereto shall be binding upon all the Lenders and all future holders of
the Loans.

                  8.5  Notice  of  Default.  No Agent  shall be  deemed  to have
knowledge  or  notice  of the  occurrence  of any  Default  or Event of  Default
hereunder  unless such Agent has  received  notice from a Lender or the Borrower
referring  to this  Agreement,  describing  such Default or Event of Default and
stating  that such  notice  is a  "notice  of  default".  In the event  that the
Administrative Agent receives such a notice, the Administrative Agent shall give
notice thereof to the Lenders.  The Administrative  Agent shall take such action
with respect to such Default or Event of Default as shall be reasonably directed
by the Required  Lenders (or, if so specified by this  Agreement,  all Lenders);
provided that unless and until the Administrative Agent shall have received such
directions,  the  Administrative  Agent may (but shall not be obligated to) take
such action, or refrain from taking such action, with respect to such Default or
Event of  Default  as it shall  deem  advisable  in the  best  interests  of the
Lenders.

                  8.6  Non-Reliance  on Agents and Other  Lenders.  Each  Lender
expressly  acknowledges  that  neither  the Agents  nor any of their  respective
officers, directors, employees, agents, attorneys-in-fact, partners, trustees or
affiliates have made any  representations or warranties to it and that no act by
any Agent hereafter  taken,  including any review of the affairs of a Loan Party
or  any  affiliate  of  a  Loan  Party,   shall  be  deemed  to  constitute  any
representation or warranty by any Agent to any Lender. Each Lender represents to
the Agents that it has, independently and without reliance upon any Agent or any
other  Lender,  and based on such  documents  and  information  as it has deemed
appropriate,  made its own  appraisal of and  investigation  into the  business,
operations,  property, financial and other condition and creditworthiness of the
Loan  Parties and their  affiliates  and made its own decision to make its Loans
hereunder and enter into this  Agreement.  Each Lender also  represents  that it
will, independently and without reliance upon any Agent or any other Lender, and
based on such  documents and  information  as it shall deem  appropriate  at the
time,  continue to make its own credit  analysis,  appraisals  and  decisions in
taking or not taking action under this  Agreement and the other Loan  Documents,
and to make such  investigation as it deems necessary to inform itself as to the
business,   operations,    property,   financial   and   other   condition   and
creditworthiness  of the Loan Parties and their affiliates.  Except for notices,
reports and other documents expressly required to be



<PAGE>
                                                                              82


furnished to the Lenders by the Administrative  Agent hereunder,  no Agent shall
have any duty or  responsibility  to provide any Lender with any credit or other
information concerning the business, operations,  property, condition (financial
or otherwise),  prospects or creditworthiness of any Loan Party or any affiliate
of a Loan Party which may come into the  possession  of such Agent or any of its
officers, directors, employees, agents, attorneys-in-fact or affiliates.

                  8.7 Indemnification. The Lenders agree to indemnify each Agent
in its  capacity  as such (to the  extent not  reimbursed  by the  Borrower  and
without limiting the obligation of the Borrower to do so), ratably  according to
their respective  Aggregate Exposure  Percentages in effect on the date on which
indemnification  is sought under this Section (or, if  indemnification is sought
after the date upon which the  Commitments  shall have  terminated and the Loans
shall have been paid in full, ratably in accordance with such Aggregate Exposure
Percentages  immediately  prior  to such  date),  from and  against  any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs,  expenses or  disbursements  of any kind whatsoever which may at any time
(including,  without limitation, at any time following the payment of the Loans)
be imposed on, incurred by or asserted against such Agent in any way relating to
or  arising  out of,  the  Commitments,  this  Agreement,  any of the other Loan
Documents or any documents  contemplated  by or referred to herein or therein or
the transactions  contemplated  hereby or thereby or any action taken or omitted
by such Agent under or in connection with any of the foregoing; provided that no
Lender  shall be liable  for the  payment of any  portion  of such  liabilities,
obligations,  losses,  damages,  penalties,  actions,  judgments,  suits, costs,
expenses or disbursements which are found by a final and nonappealable  decision
of a court of competent  jurisdiction  to have  resulted from such Agent's gross
negligence or willful  misconduct.  The agreements in this Section shall survive
the payment of the Loans and all other amounts payable hereunder.

                  8.8  Agent in Its  Individual  Capacity.  Each  Agent  and its
affiliates may make loans to, accept  deposits from and generally  engage in any
kind of business with any Loan Party as though such Agent was not an Agent. With
respect  to its Loans made or  renewed  by it,  each  Agent  shall have the same
rights  and powers  under this  Agreement  and the other Loan  Documents  as any
Lender and may exercise  the same as though it were not an Agent,  and the terms
"Lender" and "Lenders" shall include each Agent in its individual capacity.

                  8.9 Successor  Administrative  Agent. The Administrative Agent
may resign as  Administrative  Agent upon 30 days' notice to the Lenders and the
Borrower. If the Administrative Agent shall resign as Administrative Agent under
this  Agreement and the other Loan  Documents,  then the Required  Lenders shall
appoint  from  among  the  Lenders a  successor  agent  for the  Lenders,  which
successor  agent shall (unless an Event of Default under Section 7(a) or Section
7(f) with respect to the Borrower  shall have  occurred  and be  continuing)  be
subject to approval by the Borrower  (which  approval shall not be  unreasonably
withheld or  delayed),  whereupon  such  successor  agent  shall  succeed to the
rights,   powers  and  duties  of  the   Administrative   Agent,  and  the  term
"Administrative  Agent"  shall mean such  successor  agent  effective  upon such
appointment and approval,  and the former Administrative

                                                                              83

Agent's rights,  powers and duties as Administrative  Agent shall be terminated,
without  any  other  or  further  act  or  deed  on  the  part  of  such  former
Administrative  Agent or any of the parties to this  Agreement or any holders of
the Loans.  If no successor  agent has accepted  appointment  as  Administrative
Agent by the date that is 10 days  following a retiring  Administrative  Agent's
notice of resignation,  the retiring  Administrative  Agent's  resignation shall
nevertheless  thereupon  become  effective,  and the  Lenders  shall  assume and
perform all of the duties of the Administrative Agent hereunder until such time,
if any, as the Required Lenders appoint a successor agent as provided for above.
After any retiring Agent's  resignation as Agent, the provisions of this Section
8 shall inure to its  benefit as to any actions  taken or omitted to be taken by
it while it was Agent under this Agreement and the other Loan Documents.

                  8.10 Authorization to Release Liens. The Administrative  Agent
is hereby irrevocably authorized by each of the Lenders to direct the Collateral
Agent to release any Lien  covering  any  Property of the Borrower or any of its
Subsidiaries  that is the subject of a  Disposition  which is  permitted by this
Agreement or which has been consented to in accordance with Section 9.1.

                  8.11  Collateral  Agency  and  Intercreditor   Agreement.  The
Administrative Agent is hereby irrevocably authorized to execute and deliver the
Collateral  Agency and  Intercreditor  Agreement,  and each of the  Lenders,  by
becoming a party to this Agreement,  hereby  confirms its obligations  under the
Collateral Agency and Intercreditor  Agreement,  including,  without limitation,
its indemnification obligations under Section 7.6 thereof.

                  8.12   The   Arrangers,   the   Syndication   Agent   and  the
Documentation Agent. The Arrangers,  the Syndication Agent and the Documentation
Agent,  in  their  respective  capacities  as  such,  shall  have no  duties  or
responsibilities,  and shall incur no  liability,  under this  Agreement and the
other Loan Documents.

                            SECTION 9. MISCELLANEOUS

                  9.1 Amendments and Waivers.  Neither this Agreement, any other
Loan Document,  nor any terms hereof or thereof may be amended,  supplemented or
modified except in accordance with the provisions of this Section.  The Required
Lenders and each Loan Party party to the relevant  Loan  Document  may, or (with
the written consent of the Required Lenders) the  Administrative  Agent and each
Loan Party party to the relevant Loan Document may, from time to time, (a) enter
into written  amendments,  supplements or modifications  hereto and to the other
Loan Documents for the purpose of adding, deleting or revising any provisions to
this  Agreement or the other Loan Documents or changing in any manner the rights
of the Lenders or of the Loan Parties  hereunder or thereunder or (b) waive,  on
such terms and conditions as the Required Lenders, or the Administrative  Agent,
as the case may be, may specify in such  instrument,  any of the requirements of
this  Agreement  or the other Loan  Documents or any Default or Event of Default
and  its  consequences;  provided,  however,  that no  such  waiver  and no such
amendment,  supplement or modification shall (i)

forgive the principal  amount or extend the final  scheduled date of maturity of
any Loan,  extend the scheduled date of any  amortization  payment in respect of
any Term Loan,  reduce the stated rate of any interest or fee payable  hereunder
or extend the scheduled date of any payment  thereof,  or increase the amount or
extend the expiration date of any Commitment of any Lender, in each case without
the consent of each Lender  directly  affected  thereby;  (ii) amend,  modify or
waive any  provision of this Section 9.1 or reduce any  percentage  specified in
the definition of Required Lenders or Required  Prepayment  Lenders,  consent to
the assignment or transfer by the Borrower of any of its rights and  obligations
under this  Agreement and the other Loan  Documents,  direct the  Administrative
Agent to give its consent to release all or substantially  all of the Collateral
or to release all or substantially  all of the Subsidiary  Guarantors from their
obligations under the Guarantee and Collateral  Agreement,  in each case without
the consent of all Lenders; (iii) amend, modify or waive any condition precedent
to any  extension  of  credit  under  any  Facility  set  forth in  Section  4.2
(including,  without  limitation,  in connection  with any waiver of an existing
Default  or Event of  Default)  without  the  consent of the  Majority  Facility
Lenders  under such  Facility;  (iv)  reduce  the  percentage  specified  in the
definition of Majority Facility Lenders with respect to any Facility without the
written consent of all Lenders under such Facility;  (v) amend,  modify or waive
any  provision  of Section 8 without the  consent of the Agents;  or (vi) amend,
modify or waive any provision of Section 2.19 without the consent of each Lender
directly affected thereby; and provided,  further that the Collateral Agency and
Intercreditor  Agreement  may be amended  only in  accordance  with  Section 8.3
thereof.  Any such waiver and any such  amendment,  supplement  or  modification
shall apply  equally to each of the  Lenders and shall be binding  upon the Loan
Parties,  the Lenders,  the  Administrative  Agent and all future holders of the
Loans.  In the  case of any  waiver,  the  Loan  Parties,  the  Lenders  and the
Administrative  Agent  shall be  restored to their  former  position  and rights
hereunder  and under the  other  Loan  Documents,  and any  Default  or Event of
Default  waived  shall be  deemed to be cured  and not  continuing;  but no such
waiver shall extend to any  subsequent or other Default or Event of Default,  or
impair any right consequent thereon. Any such waiver,  amendment,  supplement or
modification  shall be  effected by a written  instrument  signed by the parties
required to sign pursuant to the foregoing provisions of this Section; provided,
that delivery of an executed  signature page of any such instrument by facsimile
transmission  shall be effective as delivery of a manually executed  counterpart
thereof.

                  9.2 Notices. All notices,  requests and demands to or upon the
respective  parties  hereto to be effective  shall be in writing  (including  by

case of a  Lender  which  becomes  a  party  to this  Agreement  pursuant  to an
Assignment and Acceptance,  in such Assignment and Acceptance or (c) in the case
of any party,  to such other address as such party may  hereafter  notify to the

no delay in exercising,  on the part of the any Agent or any Lender,  any right,
remedy,  power or privilege  hereunder or under the other Loan  Documents  shall

right,  remedy,  power or  privilege  hereunder  preclude  any other or  further
exercise thereof or the exercise of any other right, remedy, power or privilege.
The rights,  remedies,  powers and privileges herein provided are cumulative and
not exclusive of any rights, remedies, powers and privileges provided by law.

                  9.4   Survival  of   Representations   and   Warranties.   All
representations  and warranties made hereunder,  in the other Loan Documents and

incurred in connection with the  development,  preparation and execution of, and

Documents and any other documents prepared in connection  herewith or therewith,

and  thereby,   including,   without   limitation,   the  reasonable   fees  and

Lender and the Agents for all its costs and expenses incurred in connection with
the enforcement or  preservation  of any rights under this Agreement,  the other
Loan Documents

                                                                              86


and any  such  other  documents,  including,  without  limitation,  the fees and
disbursements of counsel  (including the allocated fees and expenses of in-house
counsel) to each Lender (solely during the  occurrence  and  continuation  of an
Event of Default) and of counsel to the Agents, (c) to pay, indemnify,  and hold
each Lender and the Agents  harmless from, any and all recording and filing fees
and any and all  liabilities  with  respect to, or  resulting  from any delay in
paying,  stamp,  excise  and  other  taxes,  if any,  which  may be  payable  or
determined  to be payable in  connection  with the execution and delivery of, or
consummation or  administration  of any of the transactions  contemplated by, or
any amendment,  supplement or modification of, or any waiver or consent under or
in respect  of,  this  Agreement,  the other Loan  Documents  and any such other
documents,  and (d) to pay,  indemnify,  and hold each Lender and the Agents and
their respective officers, directors,  trustees, employees,  affiliates, agents,
partners and  controlling  persons  (each,  an  "Indemnitee")  harmless from and
against any and all other liabilities,  obligations, losses, damages, penalties,
actions,  judgments,  suits,  costs and expenses or disbursements of any kind or
nature  whatsoever  with  respect  to  the  execution,  delivery,   enforcement,
performance and  administration of this Agreement,  the other Loan Documents and
any such other documents,  including,  without limitation,  any of the foregoing
relating to the use of proceeds of the Loans or the violation of,  noncompliance
with or liability under, any  Environmental  Law applicable to the operations of
the Borrower any of its Subsidiaries or any of the Properties (all the foregoing
in this clause (d), collectively, the "Indemnified Liabilities"), provided, that
the Borrower shall have no obligation  hereunder to any Indemnitee  with respect
to Indemnified  Liabilities to the extent such Indemnified  Liabilities resulted
from the gross  negligence  or willful  misconduct of such  Indemnitee.  Without
limiting  the  foregoing,  and to the extent  permitted by  applicable  law, the
Borrower agrees not to assert and to cause its Subsidiaries  not to assert,  and
hereby waives and agrees to cause its  Subsidiaries so to waive,  all rights for
contribution  or any other  rights  of  recovery  with  respect  to all  claims,
demands, penalties, fines, liabilities, settlements, damages, costs and expenses
of  whatever  kind  or  nature,   in  each  case  solely  under  or  related  to
Environmental  Laws, that any of them might have by statute or otherwise against
any  indemnitee.  The agreements in this Section shall survive  repayment of the
Loans and all other amounts payable hereunder.

                  9.6 Successors and Assigns;  Participations  and  Assignments;
Replacement.  (a) This Agreement  shall be binding upon and inure to the benefit
of the Borrower,  the Lenders,  the Agents,  all future holders of the Loans and
their respective successors and assigns, except that the Borrower may not assign
or transfer any of its rights or obligations  under this  Agreement  without the
prior written consent of the Agents and each Lender.

                  (b) Any Lender may,  without the consent of the  Borrower,  in
accordance with applicable law, at any time sell to one or more banks, financial
institutions or other entities (each, a "Participant")  participating  interests
in any Loan owing to such  Lender,  any  Commitment  of such Lender or any other
interest of such Lender  hereunder  and under the other Loan  Documents.  In the
event of any such sale by a Lender of a participating interest to a Participant,
such  Lender's  obligations  under this  Agreement to the other  parties to this
Agreement shall remain  unchanged,  such Lender shall remain solely  responsible
for the  


<PAGE>
                                                                              87


performance  thereof,  such Lender  shall remain the holder of any such Loan for
all purposes under this Agreement and the other Loan Documents, and the Borrower
and the Agents shall  continue to deal solely and  directly  with such Lender in
connection with such Lender's  rights and  obligations  under this Agreement and
the other  Loan  Documents.  In no event  shall any  Participant  under any such
participation have any right to approve or consent to any amendment or waiver of
any provision of any Loan Document,  or any consent to any departure by any Loan
Party  therefrom,  except to the extent that such  amendment,  waiver or consent
would  reduce the  principal  of, or interest  on, the Loans or any fees payable
hereunder, or postpone the date of the final maturity of the Loans, in each case
to the extent subject to such participation. The Borrower agrees that if amounts
outstanding  under this Agreement and the Loans are due or unpaid, or shall have
been  declared or shall have become due and payable  upon the  occurrence  of an
Event of Default,  each  Participant  shall, to the maximum extent  permitted by
applicable  law,  be  deemed  to have the  right of  setoff  in  respect  of its
participating  interest in amounts owing under this Agreement to the same extent
as if the amount of its  participating  interest were owing  directly to it as a
Lender under this  Agreement,  provided that, in purchasing  such  participating
interest,  such  Participant  shall be deemed to have  agreed to share  with the
Lenders the  proceeds  thereof as  provided in Section  9.7(a) as fully as if it
were a Lender hereunder. The Borrower also agrees that each Participant shall be
entitled to the  benefits of Sections  2.20,  2.21 and 2.22 with  respect to its
participation in the Commitments and the Loans  outstanding from time to time as
if it was a Lender; provided that, in the case of Section 2.21, such Participant
shall have complied with the requirements of said Section and provided, further,
that no Participant  shall be entitled to receive any greater amount pursuant to
any such Section than the transferor  Lender would have been entitled to receive
in respect of the amount of the  participation  transferred  by such  transferor
Lender to such Participant had no such transfer occurred.

                  (c)  Any  Lender  (an  "Assignor")  may,  in  accordance  with
applicable  law,  at any time and from time to time  assign to any Lender or any
affiliate  thereof or any Approved Fund or, with the consent of the Borrower and
the  Administrative  Agent  (which,  in each  case,  shall  not be  unreasonably
withheld or delayed),  to an additional  bank,  financial  institution  or other
entity (an "Assignee") all or any part of its rights and obligations  under this
Agreement pursuant to an Assignment and Acceptance, substantially in the form of
Exhibit E, executed by such Assignee and such Assignor  (and,  where the consent
of  the  Borrower  or the  Administrative  Agent  is  required  pursuant  to the
foregoing  provisions,  by the Borrower and such other Persons) and delivered to
the  Administrative  Agent for its  acceptance  and  recording in the  Register;
provided that no such  assignment  to an Assignee  (other than any Lender or any
affiliate  thereof or any  Approved  Fund)  shall be in an  aggregate  principal
amount of less than  $5,000,000  (other than in the case of an assignment of all
of a Lender's  interests under this  Agreement),  unless otherwise agreed by the
Borrower and the  Administrative  Agent. Any such assignment need not be ratable
as  among  the  Facilities.  Upon  such  execution,   delivery,  acceptance  and
recording,  from and  after  the  effective  date  determined  pursuant  to such
Assignment and Acceptance,  (x) the Assignee  thereunder shall be a party hereto
and, to the extent provided in such  Assignment and Acceptance,  have the rights
and  obligations  of a Lender  hereunder  with a Commitment  and/or Loans as set
forth therein,



<PAGE>
                                                                              88


and (y) the Assignor thereunder shall, to the extent provided in such Assignment
and Acceptance,  be released from its obligations  under this Agreement (and, in
the case of an Assignment  and Acceptance  covering all of an Assignor's  rights
and obligations  under this  Agreement,  such Assignor shall cease to be a party
hereto).  Notwithstanding  any  provision  of this  Section,  the consent of the
Borrower shall not be required for any assignment  which occurs at any time when
any Event of Default  under  Section  7(a) or 7(f) with  respect to the Borrower
shall have occurred and be continuing.

                  (d) The Administrative Agent, on behalf of the Borrower, shall
maintain at its address referred to in Section 9.2 a copy of each Assignment and
Acceptance  delivered to it and a register (the  "Register") for the recordation
of the names and addresses of the Lenders and the  Commitments of, and principal
amount of the Loans owing to, each Lender from time to time.  The entries in the
Register  shall  be  conclusive,  in the  absence  of  manifest  error,  and the
Borrower, the Administrative Agent and the Lenders shall treat each Person whose
name is  recorded  in the  Register  as the  owner of the  Loans  and any  Notes
evidencing such Loans recorded  therein for all purposes of this Agreement.  Any
assignment of any Loan,  whether or not evidenced by a Note,  shall be effective
only upon  appropriate  entries with respect  thereto being made in the Register
(and each Note shall expressly so provide). Any assignment or transfer of all or
part of a Loan evidenced by a Note shall be registered on the Register only upon
surrender for registration of assignment or transfer of the Note evidencing such
Loan, accompanied by a duly executed Assignment and Acceptance; thereupon one or
more new Notes in the same  aggregate  principal  amount  shall be issued to the
designated  Assignee,  and the old Notes shall be returned by the Administrative
Agent to the Borrower  marked  "cancelled".  The Register shall be available for
inspection by the Borrower or any Lender at any reasonable time and from time to
time upon reasonable prior notice.

                  (e) Upon its receipt of an Assignment and Acceptance  executed
by an Assignor and an Assignee  (and, in any case where the consent of any other
Person is required by Section 9.6(c),  by each such other Person)  together with
payment to the  Administrative  Agent of a  registration  and  processing fee of
$3,500  (provided  that only one such fee shall be  payable in  connection  with
simultaneous  assignments to more than one Approved  Fund),  the  Administrative
Agent shall (i) promptly  accept such  Assignment and Acceptance and (ii) on the
effective date  determined  pursuant  thereto record the  information  contained
therein in the Register and give notice of such  acceptance  and  recordation to
the Lenders and the Borrower.  On or prior to such effective date, the Borrower,
at  its  own  expense,   upon   request,   shall  execute  and  deliver  to  the
Administrative   Agent  (in  exchange  for  the  Revolving  Credit  Note  and/or
applicable  Term Notes of the  assigning  Lender) a new  Revolving  Credit  Note
and/or  applicable Term Notes, as the case may be, to the order of such Assignee
in an amount equal to the Revolving  Credit  Commitment  and/or  applicable Term
Loans, as the case may be, assumed or acquired by it pursuant to such Assignment
and Acceptance and, if the Assignor has retained a Revolving  Credit  Commitment
and/or Term Loans, as the case may be, upon request, a new Revolving Credit Note
and/or Term Notes, as the case may be, to the order of the Assignor in an amount
equal to the Revolving Credit  Commitment  and/or  applicable Term 


<PAGE>
                                                                              89


Loans,  as the case may be,  retained  by it  hereunder.  Such new Note or Notes
shall be dated the Closing  Date and shall  otherwise be in the form of the Note
or Notes replaced thereby.

                  (f) For  avoidance  of doubt,  the  parties to this  Agreement
acknowledge that the provisions of this Section concerning  assignments of Loans
and Notes relate only to absolute  assignments  and that such  provisions do not
prohibit assignments creating security interests,  any pledge or assignment by a
Lender  of any  Loan or Note to any  Federal  Reserve  Bank in  accordance  with
applicable law.

                  (g) The  Borrower  shall be  permitted  to replace with one or
more replacement Lenders any Lender which (i) requests reimbursement for amounts
owing pursuant to Section 2.20 or 2.21,  (ii) has received a written notice from
the  Borrower of an  impending  change in law that would  entitle such Lender to
payment of additional  amounts  under  Section 2.20 or 2.21,  unless such Lender
designates  a  different  lending  office  before  such  change  in law  becomes
effective and such alternate  lending office  obviates the need for the Borrower
to make  payments of additional  amounts  under  Section 2.20 or 2.21,  (iii) is
affected in the manner described in Section 2.18 or 2.23 and as a result thereof
any of the actions  described in Section  2.18 or 2.23,  as the case may be, are
required  to be  taken,  (iv)  does  not  consent  to  any  proposed  amendment,
supplement,  modification, consent or waiver of any provisions of this Agreement
or any other Loan  Document as  contemplated  by Section 9.1, or (v) defaults in
its  obligation  to make  Loans;  provided  that (A) such  replacement  does not
conflict  with  any  Requirement  of Law,  (B) no Event of  Default  shall  have
occurred and be  continuing  at the time of such  replacement,  (C) the Borrower
shall repay (or the replacement bank or institution shall purchase,  at par) all
Loans and  other  amounts  owing to such  replaced  Lender  prior to the date of
replacement,  (D) the  Borrower  shall be liable to such  replaced  Lender under
Section  2.22 if any  Eurodollar  Loan owing to such  replaced  Lender  shall be
prepaid  (or  purchased)  other  than on the  last  day of the  Interest  Period
relating  thereto,  (E) the replacement  bank or  institution,  if not already a
Lender,  shall be reasonably  satisfactory to the Administrative  Agent, (F) the
replaced  Lender shall be obligated to make such  replacement in accordance with
the  provisions of this Section 9.6 (provided  that the Borrower or  replacement
Lender shall be obligated to pay the registration and processing fee), (G) until
such time as such replacement  shall be consummated,  the Borrower shall pay all
additional  amounts (if any)  required  pursuant to Section 2.20 or 2.21, as the
case may be, (H) any such replacement  shall not be deemed to be a waiver of any
rights which the Borrower,  the  Administrative  Agent or any other Lender shall
have against the replaced Lender, and (I) any replacement contemplated by clause
(iv) above shall be  permitted  only if the consent of Lenders  holding at least
90% of the aggregate  unpaid principal amount of the Loans then outstanding plus
the aggregate amount of undrawn Commitments then in effect is obtained,  but the
consent of one or more of the other  Lenders  is not  obtained  (other  than the
withholding of any required consent pursuant to clauses (i) or (ii) of the first
proviso of Section 9.1), and each  replacement  Lender  consents to the proposed
amendment, supplement, modification, consent or waiver.

                  9.7 Adjustments;  Set-off.  (a) Except to the extent that this
Agreement provides for payments to be allocated to a particular Lender or to the
Lenders under a particular Facility, if any Lender (a "Benefitted Lender") shall
at any time receive any payment of all or part of the  Obligations  owing to it,
or  receive  any  collateral  in  respect   thereof   (whether   voluntarily  or
involuntarily,  by  set-off,  pursuant  to events or  proceedings  of the nature
referred to in Section 7(f), or  otherwise),  in a greater  proportion  than any
such payment to or collateral  received by any other Lender,  if any, in respect
of such other Lender's  Obligations,  such Benefitted  Lender shall purchase for
cash from the other  Lenders a  participating  interest in such  portion of each
such other  Lender's  Obligations,  or shall provide such other Lenders with the
benefits of any such collateral,  as shall be necessary to cause such Benefitted
Lender to share the excess payment or benefits of such  collateral  ratably with
each of the  Lenders;  provided,  however,  that if all or any  portion  of such
excess payment or benefits is thereafter  recovered from such Benefitted Lender,
such purchase shall be rescinded,  and the purchase price and benefits returned,
to the extent of such recovery, but without interest.

                  (b) In  addition  to any rights and  remedies  of the  Lenders
provided by law,  each Lender shall have the right,  without prior notice to the
Borrower,  any such notice being expressly  waived by the Borrower to the extent
permitted by  applicable  law,  upon any amount  becoming due and payable by the
Borrower  hereunder  (whether  at  the  stated  maturity,   by  acceleration  or
otherwise), to set off and appropriate and apply against such amount any and all
deposits  (general or special,  time or demand,  provisional  or final),  in any
currency,  and any other credits,  indebtedness or claims,  in any currency,  in
each case  whether  direct or  indirect,  absolute  or  contingent,  matured  or
unmatured,  at any time  held or owing by such  Lender  or any  branch or agency
thereof to or for the credit or the account of the Borrower, as the case may be.
Each Lender agrees promptly to notify the Borrower and the Administrative  Agent
after any such setoff and  application  made by such Lender,  provided  that the
failure to give such  notice  shall not affect the  validity  of such setoff and
application.

                  9.8  Counterparts.  This  Agreement  may be executed by one or
more of the parties to this  Agreement  on any number of separate  counterparts,
and all of said  counterparts  taken  together shall be deemed to constitute one
and  the  same  instrument.  Delivery  of an  executed  signature  page  of this
Agreement by facsimile transmission shall be effective as delivery of a manually
executed counterpart hereof. A set of the copies of this Agreement signed by all
the parties shall be lodged with the Borrower and the Administrative Agent.

                  9.9  Severability.  Any provision of this  Agreement  which is
prohibited or unenforceable in any jurisdiction  shall, as to such jurisdiction,
be ineffective to the extent of such  prohibition  or  unenforceability  without
invalidating  the  remaining  provisions  hereof,  and any such  prohibition  or
unenforceability   in  any   jurisdiction   shall  not   invalidate   or  render
unenforceable such provision in any other jurisdiction.

                  9.10 Integration.  This Agreement and the other Loan Documents
represent  the  agreement  of the  Borrower,  the  Administrative  Agent and the

subject matter hereof, and there are no promises, undertakings,  representations

                  9.11   GOVERNING  LAW.  THIS  AGREEMENT  AND  THE  RIGHTS  AND
OBLIGATIONS  OF THE  PARTIES  UNDER THIS  AGREEMENT  SHALL BE  GOVERNED  BY, AND
CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

                  9.12  Submission To Jurisdiction; Waivers. The Borrower hereby
irrevocably and unconditionally:

                  (a) submits for itself and its Property in any legal action or
         proceeding  relating to this  Agreement and the other Loan Documents to
         which it is a party, or for recognition and enforcement of any judgment
         in respect thereof,  to the non-exclusive  general  jurisdiction of the
         courts of the State of New York,  the  courts of the  United  States of
         America for the Southern  District of New York,  and  appellate  courts
         from any thereof;

                  (b) to the extent  permitted by applicable law,  consents that
         any such action or proceeding  may be brought in such courts and waives
         any  objection  that it may now or  hereafter  have to the venue of any
         such  action or  proceeding  in any such  court or that such  action or
         proceeding was brought in an inconvenient court and agrees not to plead
         or claim the same;

                  (c) agrees  that  service  of  process  in any such  action or
         proceeding  may be effected by mailing a copy thereof by  registered or
         certified  mail (or any  substantially  similar form of mail),  postage
         prepaid,  to the Borrower at its address set forth in Section 9.2 or at
         such other  address of which the  Administrative  Agent shall have been
         notified pursuant thereto;

                  (d)  agrees  that  nothing  herein  shall  affect the right to
         effect service of process in any other manner permitted by law or shall
         limit the right to sue in any other jurisdiction; and

                  (e) waives,  to the maximum  extent not prohibited by law, any
         right it may have to claim or recover in any legal action or proceeding
         referred  to in  this  Section  any  special,  exemplary,  punitive  or
         consequential damages.

                  9.13 Acknowledgements. The Borrower hereby acknowledges that:

                  (a)  it has  been  advised  by  counsel  in  the  negotiation,
         execution and delivery of this Agreement and the other Loan Documents;



<PAGE>
                                                                              92


                  (b)  neither the  Administrative  Agent nor any Lender has any
         fiduciary  relationship  with or duty to the Borrower arising out of or
         in connection  with this Agreement or any of the other Loan  Documents,
         and the relationship  between  Administrative Agent and Lenders, on one
         hand,  and the Borrower,  on the other hand, in connection  herewith or
         therewith is solely that of debtor and creditor; and

                  (c) no joint  venture is  created  hereby or by the other Loan
         Documents   or   otherwise   exists  by  virtue  of  the   transactions
         contemplated  hereby  among the Lenders or among the  Borrower  and the
         Lenders.

                  9.14  Confidentiality.  Each of the  Agents  and  the  Lenders
agrees to keep  confidential  all non-public  information  provided to it by any
Loan Party  pursuant to this  Agreement that is designated by such Loan Party as
confidential; provided that nothing herein shall prevent any Agent or any Lender
from  disclosing any such  information  (a) to the  Administrative  Agent or any
other Lender,  (b) to any  Participant  or Assignee  (each, a  "Transferee")  or
prospective Transferee which receives such information having been made aware of
the  confidential  nature thereof and which agrees to comply with the provisions
of this Section 9.14, (c) any of its employees,  directors and officers who need
to know such  information  in accordance  with customary  banking  practices and
affiliates of Lenders, employees, directors and officers of such affiliates, and
agents,  accountants,  attorneys and other professional  advisors of Lenders who
receive  such  information  having  been made aware of the  confidential  nature
thereof and agree to comply with the  provisions of this Section 9.14,  (d) upon
the request or demand of any Governmental Authority having jurisdiction over it,
(e) in response to any order of any court or other Governmental  Authority or as
may otherwise be required pursuant to any Requirement of Law, (f) if required to
do so in connection  with any  litigation or similar  proceeding,  (g) which has
been publicly  disclosed  other than in breach of this Section 9.14,  (h) to the
National  Association of Insurance  Commissioners or any securities  exchange or
any  similar  organization,  or any  nationally  recognized  rating  agency that
requires  access  to  information  about  a  Lender's  investment  portfolio  in
connection  with ratings issued with respect to such Lender or (i) in connection
with the exercise of any remedy  hereunder or under any other Loan Document.  In
the event that any Lender discloses any information pursuant to clauses (d), (e)
or (f) of the preceding  sentence,  such Lender will give notice  thereof to the
Borrower if such Lender is lawfully permitted to do so and if the giving of such
notice will not, in the judgment of such Lender,  be materially  disadvantageous
to it.

                  9.15  Accounting  Changes.  In the event that any  "Accounting
Change" (as defined  below)  shall occur and such change  results in a change in
the method of  calculation  of financial  covenants,  standards or terms in this
Agreement,  then the Borrower and the  Administrative  Agent agree to enter into
negotiations  in order to  amend  such  provisions  of this  Agreement  so as to
equitably  reflect  such  Accounting  Changes  with the desired  result that the
criteria for  evaluating the Borrower's  financial  condition  shall be the same
after such Accounting  Changes as if such Accounting  Changes had not been made.
Until such time as such an amendment  shall have been  executed and delivered by
the Borrower,  the

Administrative   Agent  and  the  Required  Lenders,  all  financial  covenants,
standards  and  terms in this  Agreement  shall  continue  to be  calculated  or
construed as if such Accounting Changes had not occurred.  "Accounting  Changes"
refers to changes in (i) accounting  principles  required by the promulgation of
any rule,  regulation,  pronouncement  or  opinion by the  Financial  Accounting
Standards Board of the American Institute of Certified Public Accountants or, if
applicable,  the  Securities and Exchange  Commission (or successors  thereto or
agencies  with similar  functions)  or (ii) the  application  by the Borrower of
accounting principles.

                  9.16 WAIVERS OF JURY TRIAL.  THE BORROWER,  THE AGENTS AND THE
LENDERS HEREBY IRREVOCABLY AND UNCONDITIONALLY  WAIVE TRIAL BY JURY IN ANY LEGAL

                           (i) In the event that any or all amounts  owing under
         the Senior  Obligations  have become,  or have been declared to be, due
         and  payable  and have not been paid in  accordance  with  their  terms
         (except in  circumstances  when the succeeding  paragraph (ii) shall be
         applicable), then and in any such event, any payment or distribution of
         any kind or character, whether in cash, property or securities,  which,
         but for the subordination  provisions contained herein, would otherwise
         be payable  or  deliverable  to the  Subordinated  Creditor  upon or in
         respect of the Subordinated  Obligations  shall instead be paid over or
         delivered to the Senior Creditor  Representative for the benefit of the
         Senior Creditors,  and the Subordinated  Creditor shall not in any such
         event receive any such payment or distribution or any benefit therefrom
         unless and until the Senior  Obligations shall have been fully paid and
         satisfied.

                           (ii)  In  the  event  of  any  liquidation  or  other
         winding-up  of the  Borrower  or in  the  event  of  any  receivership,
         insolvency,  reorganization or bankruptcy  proceedings,  assignment for
         the benefit of creditors or any  proceeding  by or against the Borrower
         for any relief under any bankruptcy,  reorganization  or insolvency law
         or laws,  Federal or state, or any law,  Federal or state,  relating to
         the relief of debtors,  readjustment of  indebtedness,  reorganization,
         composition or extension of indebtedness,  then, and in any such event,
         all Senior  Obligations  shall first be paid in full before any payment
         or distribution is made in respect of the Subordinated Obligations, and
         any payment or distribution of any kind or character,  whether in cash,
         property or securities,  which,  but for the  subordination  provisions
         contained  herein,  would  otherwise be payable or  deliverable  to the
         Subordinated   Creditor   upon  or  in  respect  of  the   Subordinated
         Obligations,  shall  instead  be paid over or  delivered  to the Senior
         Creditor  Representative  for the benefit of the Senior Creditors,  and
         the  Subordinated  Creditor  shall  not  receive  any such  payment  or
         distribution  or any  benefit  therefrom  unless  and until the  Senior
         Obligations shall have been fully paid and satisfied.

                           (iii) If any payment,  distribution  or security,  or
         the  proceeds  of  any  thereof,   is  collected  or  received  by  the
         Subordinated Creditor in respect of the Subordinated  Obligations,  and
         such  collection  or receipt is  prohibited  by  paragraph  (i) or (ii)
         above, the  Subordinated  Creditor will forthwith turn over the same to
         the  Senior  Creditor  Representative  for the  benefit  of the  Senior
         Creditors, in each case in the form received (except for endorsement or
         the assignment of the Subordinated  Creditor when necessary) and, until
         so turned  over,  the same  shall be held in trust by the  Subordinated
         Creditor as the property of the Senior Creditors.  Notwithstanding  the
         above or anything else contained  herein, so long as no event described
         in paragraph (i) or (ii) above has occurred, the Borrower may make, and
         the  Subordinated  Creditor  


<PAGE>
                                                                               2


         shall  be  entitled  to  receive  and  keep,  without  regard  to these
         subordination  provisions,  all interest  payments  when  due under the
         Subordinated Obligations in accordance with the terms thereof.

                  II. Subject to the payment in full of all Senior  Obligations,
the Subordinated  Creditor shall be subrogated to the rights of the holder(s) of
the Senior  Obligations (to the extent of payments or  distributions  previously
made to such holders  pursuant to the  provisions of Section I above) to receive
any and all payments or distributions  made in respect of the Senior Obligations
until all amounts owing on the Subordinated  Obligations  shall be paid in full.
No  payments  or  distributions  applicable  to  Senior  Obligations  which  the
Subordinated  Creditor  receives by reason of being  subrogated to the rights of
the holders of Senior Obligations  pursuant to the provisions of this Section II
shall,  as among the Borrower,  its creditors other than the holder(s) of Senior
Obligations  and the  Subordinated  Creditor,  be deemed to be a payment  by the
Borrower,  to or for the account of the  Subordinated  Obligations;  and for the
purposes of such subrogation, no payments or distributions to the holders of the
Senior Obligations of any cash, property or securities to which the Subordinated
Creditor would be entitled to except for these subordination provisions,  and no
payment over pursuant to these subordination provisions to the holders of Senior
Obligations by the Subordinated  Creditor shall, as between the Borrower and its
creditors  other than the  holders of Senior  Obligations  and the  Subordinated
Obligations,  be deemed to be a payment by the Borrower to or for the account of
the Senior Obligations,  it being understood that these subordination provisions
are  intended  solely for the purpose of  defining  the  relative  rights of the
Subordinated  Creditor, on the one hand, and the Senior Creditors,  on the other
hand, and nothing contained in this Section or elsewhere in these  subordination
provisions  is intended to or shall  impair,  as between  the  Borrower  and its
creditors other then the Senior  Creditors and the  Subordinated  Creditor,  the
obligation of the Borrower,  which is absolute and unconditional,  to pay to the
Subordinated  Creditor,  subject  to the  rights of the  Senior  Creditors,  the
amounts due and owing under the  Subordinated  Obligations  as and when the same
shall become due and payable in accordance  with their terms,  or is intended to
or shall affect the relative rights of the  Subordinated  Creditor and creditors
of the Borrower, other than the Senior Creditor.

                  III. The  Subordinated  Creditor  consents  that,  without the
necessity of any reservation of rights against the  Subordinated  Creditor,  and
without notice to or further assent by the Subordinated Creditor, (a) any demand
for payment of any Senior  Obligation  may be rescinded in whole or in part, and
any Senior  Obligation  may be  continued,  and the Senior  Obligations,  or the
liability  of the Borrower or any other party upon or for any part  thereof,  or
any collateral  security or guaranty  therefor,  or right of offset with respect
thereto,  may,  from time to time,  in whole or in part,  be renewed,  extended,
modified, accelerated, compromised, waived, surrendered, or released and (b) the
Credit Agreement,  the other Loan Documents  referred to therein,  and any other
document or  instrument  evidencing  or  governing  the term of any other Senior
Obligations  or  any  other  collateral  security  documents  or  guaranties  or
documents in connection with the Credit Agreement or the Senior  Obligations may
be amended,  modified,  supplemented or terminated,  in whole or in part, as the
Senior

Creditors may deem advisable  from time to time, and any collateral  security at
any time held by the  Senior  Creditors  for the  payment  of any of the  Senior
Obligations may be sold,  exchanged,  waived,  surrendered or released,  in each
case,  all without  notice to or further  assent by the  Subordinated  Creditor,
which will remain bound under these  subordination  provisions,  and all without
impairing,  abridging,  releasing or affecting  the  subordination  provided for
herein, notwithstanding any such renewal, extension, modification, acceleration,
compromise,   amendment,   supplement,   termination,  sale,  exchange,  waiver,
surrender or release. The Subordinated Creditor waives any and all notice of the
creation,  modification,  renewal,  extension  or  accrual  of any of the Senior
Obligations  and notice of or proof of  reliance  by the Senior  Creditors  upon
these subordination provisions, and the Senior Obligations and any of them shall
conclusively be deemed to have been created,  contracted or incurred in reliance
upon these subordination  provisions,  and all dealings between the Borrower, on
the one hand, and the Senior  Creditors,  on the other,  shall be deemed to have
been  consummated  in  reliance  upon  these   subordination   provisions.   The
Subordinated  Creditor  acknowledges and agrees that in entering into the Credit
Agreement and in making funds  available  thereunder  the Senior  Creditors have
relied upon these subordination provisions.

         IV.  As used  herein,  (i) the  expressions  "prior  payment  in full,"
"payment  in full,"  "paid in full",  "fully paid and  satisfied"  and any other
similar terms or phrases when used with respect to the Senior  Obligations shall

                               Pending Proceedings
                               -------------------

     By means of a  Relocation  Order,  released  March 14,  1997 by the Federal
Communications  Commission ("FCC"), and a Modification Order,  released June 24,
1997 by the Public  Safety  and  Private  Wireless  Division,  Wireless  Telecom
munications  Bureau of the FCC, the FCC relocated certain Digital Electronic Mes
sage  Service  ("DEMS")  licenses,  including  those held by the Company and its
respec  tive  subsidiaries,  in the 18 GHz  band to the 24 GHz  band.  Both  the
Relocation  Order and the Modification  Order were subject to an  administrative
appeal  period.  During this period,  five parties filed  petitions with the FCC
seeking either partial or full  reconsideration  or review of one or both of the
orders.  The parties --  BellSouth  Corporation,  WinStar  Communications,  Inc.
("WinStar"),  Millimeter Wave Carrier  Association,  Inc., DirecTV  Enterprises,
Inc.  and WebCel  Communications,  Inc. --  challenged,  inter  alia,  the FCC's
issuance  of the  Relocation  Order  without  conducting  a notice  and  comment
rulemaking proceeding. WinStar withdrew its Petition for Clarification regarding
the Relocation Order on October 7, 1997.

     In addition, DIRECTV Enterprises,  Inc. has filed a petition for rulemaking
with the FCC, requesting that the FCC grant permission for DIRECTV,  and others,
to construct and operate  broadcast  satellite uplink facilities on a portion of
the 24 GHz frequencies allocated and granted to DEMS licensees.

     On September 6, 1996, Teledesic Corporation filed a petition seeking
the dismissal of 174 applications for additional  transmission  (nodal) stations
in seven li censed MSI DEMS markets,  and the  rescission of existing  licenses,
then held by or belonging to MSI or DSC. In its petition, Teledesic claimed that
its  then-proposed  satellite  system was  incompatible  with existing  licensed
terrestrial  networks in the 18 GHz band,  that the FCC's initial  grants of the
DEMS licenses to MSI and DSC was inappropriate,  and that MSI and DSC had failed
to construct and operate their licensed  facilities in compliance with the FCC's
rules.

     In their  above-described  petitions for  reconsideration of the Relocation
Order,  a number of parties  raised  substantially  similar  arguments  to those
initially raised by Teledesic  against the validity of the licenses now held by,
and the  con  structed  DEMS  facilities  now  owned  by,  the  Company  and its
respective subsidiaries.

     In November and December  1996,  the FCC inspected  each of the MSI and DSC
DEMS  facilities  and  determined  that  the  companies  had  complied  with all
applicable construction and operational requirements.  In letters dated April 2,
1997,

and April 8, 1997,  the FCC  notified  MSI and DSC,  respectively,  that the FCC
"concluded  its  inquiry"  and  "determined  not to take any further  action" in
connection with the investigation.  Moreover, on February 24, 1997, the Company,
MSI and DSC entered  into an  agreement  pursuant to which  Teledesic  agreed to
withdraw its petition and bear some of the cost of relocating  MSI's,  DSC's and
the Company's 18 GHz DEMS systems to the 24 GHz band, conditioned upon the FCC's
relocation  of 18 GHz DEMS  licensees  to the 24 GHz band.  On March  21,  1997,
Teledesic  filed a  motion  to  withdraw  its  petition  against  MSI's  pending
applications and MSI's and DSC's licenses, which such motion is pending.

                              SECTION 2. GUARANTEE

                  2.1 Guarantee.  (a) Each of the Guarantors hereby, jointly and
severally,  unconditionally and irrevocably, guarantees to the Collateral Agent,
for the ratable benefit of the Secured Parties and their respective  successors,
indorsees,  transferees  and  assigns,  the  prompt  and  complete  payment  and
performance  by the  Borrower  when due  (whether  at the  stated  maturity,  by
acceleration or otherwise) of the Secured Obligations.

                  (b) Anything  herein or in any other Security  Document to the
contrary notwithstanding,  the maximum liability of each Guarantor hereunder and
under the other Security Documents shall in no event exceed the amount which can
be guaranteed by such Guarantor under applicable federal and state laws relating
to the insolvency of debtors  (after giving effect to the right of  contribution
established in Section 2.2).

                  (c) Each Guarantor agrees that the Secured  Obligations may at
any time and from  time to time  exceed  the  amount  of the  liability  of such
Guarantor  hereunder without impairing the guarantee contained in this Section 2
or  affecting  the rights and  remedies of the  Collateral  Agent or any Secured
Party hereunder.

                  (d) The guarantee  contained in this Section 2 shall remain in
full force and effect until all the Secured  Obligations  and the obligations of
each Guarantor  under the guarantee  contained in this Section 2 shall have been
satisfied  by payment in full and all Secured  Obligation  Commitments  shall be
terminated, notwithstanding that from time to time the Borrower may be free from
any Secured Obligations.

                  (e) No payment made by the  Borrower,  any of the  Guarantors,
any  other  guarantor  or any other  Person  or  received  or  collected  by the
Collateral Agent or any Secured Party from the Borrower,  any of the Guarantors,
any other guarantor or any other Person by virtue of any action or proceeding or
any set-off or  appropriation or application at any time or from time to time in
reduction of or in payment of the Secured Obligations shall be deemed to modify,
reduce,  release or otherwise  affect the liability of any  Guarantor  hereunder
which shall,

                                                                              10



notwithstanding  any such payment (other than any payment made by such Guarantor
in respect of the Secured  Obligations or any payment received or collected from
such  Guarantor in respect of the Secured  Obligations),  remain  liable for the
Secured  Obligations  up to the maximum  liability of such  Guarantor  hereunder
until  the  Secured  Obligations  are  paid in full and all  Secured  Obligation
Commitments are terminated.

                  2.2 Right of  Contribution.  Each Guarantor hereby agrees that
to the extent that a Guarantor shall have paid more than its proportionate share
of any payment  made  hereunder,  such  Guarantor  shall be entitled to seek and
receive  contribution  from and against any other Guarantor  hereunder which has
not paid its proportionate share of such payment and each other Guarantor agrees
that  it  will  contribute  its  proportionate  share  of  such  payment  to the
applicable Guarantor. Each Guarantor's right of contribution shall be subject to
the terms and  conditions  of Section  2.3. The  provisions  of this Section 2.2
shall in no respect limit the  obligations  and  liabilities of any Guarantor to
the Secured  Parties,  and each  Guarantor  shall  remain  liable to the Secured
Parties for the full amount guaranteed by such Guarantor hereunder.

                  2.3 No  Subrogation.  Notwithstanding  any payment or payments
made by any Guarantor  hereunder or any set-off or  application  of funds of any
Guarantor by any Secured Party,  no Guarantor shall be entitled to be subrogated
to any of the rights of any  Secured  Party  against  the  Borrower or any other
Guarantor or any collateral security or guarantee or right of offset held by any
Secured  Party  for the  payment  of the  Secured  Obligations,  nor  shall  any
Guarantor seek or be entitled to seek any contribution or reimbursement from the
Borrower or any other  Guarantor in respect of payments  made by such  Guarantor
hereunder,  until all amounts  owing to the Secured  Parties by the  Borrower on
account of the Secured  Obligations are paid in full and all Secured  Obligation
Commitments  are  terminated.  If any amount  shall be paid to any  Guarantor on
account  of  such  subrogation  rights  at any  time  when  all  of the  Secured
Obligations  shall not have been paid in full, such amount shall be held by such
Guarantor in trust for the Secured Parties,  segregated from other funds of such
Guarantor,  and shall, forthwith upon receipt by such Guarantor,  be turned over
to the  Collateral  Agent in the exact form  received  by such  Guarantor  (duly
indorsed by such Guarantor to the Collateral Agent, if required),  to be applied
as provided in Section 6.5.

                  2.4 Amendments,  etc. with respect to the Secured Obligations.
To the extent permitted by applicable law, each Guarantor shall remain obligated
hereunder  notwithstanding  that,  without any reservation of rights against any
Guarantor and without notice to or further  assent by any Guarantor,  any demand
for payment of any of the Secured  Obligations  made by the Collateral  Agent or
any Secured Party may be rescinded by the Collateral Agent or such Secured Party
and any of the Secured Obligations  continued,  and the Secured Obligations,  or
the  liability  of any  other  Person  upon  or for  any  part  thereof,  or any
collateral  security  or  guarantee  therefor  or right of offset  with  respect
thereto,  may,  from time to time,  in whole or in part,  be renewed,  extended,
amended, modified, accelerated,  compromised, waived, surrendered or released by
the Collateral Agent or any Secured Party, and the other Security  Documents and
any other  documents  executed and  delivered  in  connection  therewith  may be
amended,  modified,  supplemented  or  terminated,  in whole or in part,  as the
Collateral Agent or the Secured Parties

may deem advisable from time to time, and any collateral security,  guarantee or
right of offset at any time held by the  Collateral  Agent or any Secured  Party
for the  payment of the  Secured  Obligations  may be sold,  exchanged,  waived,
surrendered  or released.  Neither the  Collateral  Agent nor any Secured  Party
shall have any obligation to protect,  secure, perfect or insure any Lien at any
time held by it as security  for the Secured  Obligations  or for the  guarantee
contained in this Section 2 or any property subject thereto.

                  2.5  Guarantee  Absolute  and  Unconditional.  To  the  extent
permitted by  applicable  law, each  Guarantor  waives any and all notice of the
creation,  renewal,  extension or accrual of any of the Secured  Obligations and
notice of or proof of reliance by the Collateral Agent or any Secured Party upon
the  guarantee  contained  in this  Section  2 or  acceptance  of the  guarantee
contained in this  Section 2; the Secured  Obligations,  and any of them,  shall
conclusively be deemed to have been created, contracted or incurred, or renewed,
extended,  amended or waived,  in reliance upon the guarantee  contained in this
Section 2; and all dealings  between the Borrower and any of the Guarantors,  on
the one hand, and the  Collateral  Agent and the Secured  Parties,  on the other
hand, likewise shall be conclusively presumed to have been had or consummated in
reliance upon the guarantee contained in this Section 2. To the extent permitted
by applicable law, each Guarantor waives diligence, presentment, protest, demand
for payment and notice of default or  nonpayment  to or upon the Borrower or any
of the  Guarantors  with  respect to the  Secured  Obligations.  Each  Guarantor
understands  and agrees that the guarantee  contained in this Section 2 shall be
construed  as a  continuing,  absolute  and  unconditional  guarantee of payment
without regard to (a) the validity or enforceability of any Secured  Instrument,
Security Document or related  agreement,  any of the Secured  Obligations or any
other collateral  security therefor or guarantee or right of offset with respect
thereto  at any time or from  time to time held by the  Collateral  Agent or any
Secured Party, (b) any defense, set-off or counterclaim (other than a defense of
payment or performance)  which may at any time be available to or be asserted by
the Borrower or any other  Person  against the  Collateral  Agent or any Secured
Party, or (c) any other  circumstance  whatsoever  (with or without notice to or
knowledge  of the Borrower or such  Guarantor)  which  constitutes,  or might be
construed to constitute, an equitable or legal discharge of the Borrower for the
Secured Obligations,  or of such Guarantor under the guarantee contained in this
Section  2, in  bankruptcy  or in any other  instance.  When  making  any demand
hereunder or otherwise  pursuing its rights and remedies  hereunder  against any
Guarantor,  the Collateral Agent or any Secured Party may, but shall be under no
obligation  to,  make a similar  demand on or  otherwise  pursue such rights and
remedies as it may have against the Borrower,  any other  Guarantor or any other
Person  or  against  any  collateral  security  or  guarantee  for  the  Secured
Obligations or any right of offset with respect thereto,  and any failure by the
Collateral  Agent or any Secured  Party to make any such demand,  to pursue such
other rights or remedies or to collect any payments from the Borrower, any other
Guarantor or any other Person or to realize upon any such collateral security or
guarantee  or to  exercise  any such  right of  offset,  or any  release  of the
Borrower,  any  other  Guarantor  or any  other  Person  or any such  collateral
security,  guarantee or right of offset,  shall not relieve any Guarantor of any
obligation or liability hereunder, and shall not impair or affect the rights and
remedies,  whether  express,  implied or  available  as a matter of law,  of the
Collateral Agent or any Secured Party

                                                                              12



against any  Guarantor.  For the  purposes  hereof  "demand"  shall  include the
commencement and continuance of any legal proceedings.

                  2.6 Reinstatement.  The guarantee  contained in this Section 2
shall continue to be effective, or be reinstated,  as the case may be, if at any
time  payment,  or any  part  thereof,  of any of  the  Secured  Obligations  is
rescinded or must otherwise be restored or returned by the  Collateral  Agent or
any Secured Party upon the insolvency, bankruptcy,  dissolution,  liquidation or
reorganization  of the Borrower or any Guarantor,  or upon or as a result of the
appointment of a receiver,  intervenor or conservator  of, or trustee or similar
officer  for,  the  Borrower or any  Guarantor  or any  substantial  part of its
property, or otherwise, all as though such payments had not been made.

                  2.7 Payments.  Each Guarantor hereby  guarantees that payments
hereunder will be paid to the Collateral  Agent without  set-off or counterclaim
in Dollars at the office of the  Collateral  Agent  specified in the  Collateral

a Special Purpose Subsidiary;  provided,  that if after the date hereof there is
any change in law which requires actions in addition to those described above to
cause the security  interests  created hereby to be perfected to the same extent
as the perfection  effected by the foregoing actions under laws in effect on the

                    SECTION 4. REPRESENTATIONS AND WARRANTIES

                  To  induce  the  Secured  Parties  to  extend  credit  to  the
Borrower,  each Grantor hereby  represents and warrants to the Collateral  Agent
and each Secured Party that:

                  4.1 Credit Agreement  Representations and Warranties.  Each of
the  representations and warranties made in respect of such Grantor in Section 3
of the Credit Agreement is true and correct as of the date hereof.

                  4.2 No Other Liens.  Except for the security  interest granted
to the Collateral  Agent for the ratable benefit of the Secured Parties pursuant
to this  Agreement and the other Liens  permitted to exist on the  Collateral by
the Secured  Instruments,  such Grantor owns,  holds, or has an interest in each
item of the Collateral  free and clear of any and all Liens or claims of others.
Except as disclosed on Schedule 7 no financing  statement or other public notice
with respect to all or any part of the Collateral is on file or of record in any
public office,  except such as have been filed in favor of the Collateral Agent,
for the ratable benefit of the Secured Parties, pursuant to this Agreement or as
are permitted by the Secured Instruments.

                  4.3 Perfected Liens; Priority.  Subject to the limitations set
forth in Section 3.2, the security  interests granted pursuant to this Agreement
(a) constitute  valid perfected  security  interests in all of the Collateral in
favor of the Collateral  Agent,  for the ratable benefit of the Secured Parties,
as collateral security for such Grantor's Obligations, enforceable in accordance
with the terms  hereof  against all  creditors  of such  Grantor and any Persons
purporting to purchase any Collateral  from such Grantor and provided that, with
respect to United States  Patents and United States  registered  Trademarks  and
applications,  such perfection will not be effective under United States federal
law until the recordation of appropriate filings in the United States Patent and
Trademark Office, and with respect to United States Copyrights,  such perfection
will not be effective  under United States federal law until the  recordation of
appropriate  filings in the United States  Copyright Office and the registration
of  such  Copyrights  therein  and (b)  are  prior  to all  other  Liens  on the
Collateral in existence on the date hereof except for Liens expressly  permitted
by the Secured Instruments to be prior to the security interests created hereby.

                  4.4 Chief Executive Office. On the date hereof, such Grantor's
jurisdiction of organization  and the location of such Grantor's chief executive
office or sole place of business are specified on Schedule 4.

and the  Equipment  (other  than mobile  goods) in which a security  interest is
required  to be  perfected  by Section 3.2 are kept at the  locations  listed on
Schedule 5.

                  4.6  Farm Products.  None of the Collateral constitutes, or is
the Proceeds of, Farm Products.

                  4.7  Pledged  Securities.  (a) The  shares  of  Pledged  Stock
pledged by such  Grantor  hereunder  constitute  all the issued and  outstanding
shares of all classes of the Capital Stock of each Issuer owned by such Grantor;
provided,  that the security interest granted hereby in any Capital Stock of any
Excluded  Foreign  Subsidiary  is  limited to 65% of the  Capital  Stock of such
Excluded Foreign Subsidiary.

                  (b) All the shares of the Pledged Stock representing ownership
interests of any  Subsidiary of the Borrower  have been duly and validly  issued
and are fully paid and nonassessable.

                  (c) Such  Grantor is the record and  beneficial  owner of, and
has  good  and  marketable  title  to,  the  Pledged  Securities  pledged  by it
hereunder,  free of any and all Liens or  options in favor of, or claims of, any
other Person, except the security interest created by this Agreement.

                  (d) None of the Pledged  Stock  issued by an Issuer which is a
limited liability  company or a partnership  constitutes a "security" within the
meaning of Section 8-102 of the New York UCC .

                  4.8  Receivables.  (a) No amount payable to such Grantor under
or in connection  with any  Receivable is evidenced by any Instrument or Chattel
Paper which has not been delivered to the Collateral Agent.

                  (b) Except as set forth on Schedule 8 none of the  obligors on
any Receivables is a Governmental Authority.

                  (c) The  amounts  represented  by such  Grantor to the Secured
Parties from time to time as owing to such Grantor in respect of the Receivables
will as of such time be accurate in all material respects.

                  4.9  Intellectual  Property.  (a)  Schedule  6  lists  all (i)
registered Trademarks and Trademark applications, (ii) Patents, (iii) registered

                  (b) On the date hereof, all material  Intellectual Property is
valid,  subsisting,  unexpired and enforceable,  has not been abandoned and does
not infringe the intellectual property rights of any other Person.

                  (c)  Except as set forth in  Schedule  6, on the date  hereof,
none of the  Intellectual  Property is the subject of any licensing or franchise
agreement pursuant to which such Grantor is the licensor or franchisor.

                  (d) No holding,  decision or judgment has been rendered by any
Governmental Authority which would limit, cancel or question the validity of, or
such Grantor's  rights in, any  Intellectual  Property in any respect that could
reasonably be expected to have a Material Adverse Effect.

                  (e) No action or proceeding  is pending,  or, to the knowledge
of such Grantor,  threatened, on the date hereof against any Grantor (i) seeking
to limit,  cancel or question the validity of any Intellectual  Property or such
Grantor's  ownership interest therein,  or (ii) which, if adversely  determined,
would have a material adverse effect on the value of any Intellectual Property.


                              SECTION 5. COVENANTS

                  Each Grantor  covenants and agrees with the  Collateral  Agent
and the Secured  Parties that,  from and after the date of this Agreement  until
the  Obligations  shall  have  been  paid in full  and  all  Secured  Obligation
Commitments shall have terminated:

                  5.1  Covenants  in  Secured  Instruments.  In the case of each
Guarantor,  such Guarantor shall take, or shall refrain from taking, as the case
may be, each action that is necessary to be taken or not taken,  as the case may
be, so that no violation of any Secured  Instrument  is caused by the failure to
take such action or to refrain from taking such action by such  Guarantor or any
of its Subsidiaries.

                  5.2 Delivery of Instruments  and Chattel Paper.  If any amount
payable under or in  connection  with any of the  Collateral  shall be or become
evidenced by any Instrument or Chattel Paper,  such  Instrument or Chattel Paper
shall be  immediately  delivered to the  Collateral  Agent,  duly  indorsed in a
manner  satisfactory to the Collateral Agent, to be held as Collateral  pursuant
to this Agreement.

                  5.3  Maintenance  of  Perfected  Security  Interest;   Further
Documentation.  (a) Such Grantor shall maintain the security interest created by
this  Agreement as a perfected  security  interest  having at least the priority
described in Section 4.5 and shall  defend such  security  interest  against the
claims and demands of all Persons whomsoever.

                                                                              17



                  (b) Such Grantor will furnish to the Collateral  Agent and the
Secured Parties statements and schedules further  identifying and describing the
Collateral and such other reports in connection with the Collateral,  all as the
Collateral Agent may reasonably request, all in reasonable detail.

                  (c) Subject to the  limitations  set forth in Section  3.2, at
any time and from  time to time,  upon the  written  request  of the  Collateral
Agent,  and at the sole expense of such Grantor,  such Grantor will promptly and
duly execute and  deliver,  and have  recorded,  such  further  instruments  and
documents and take such further  actions as the Collateral  Agent may reasonably
request for the purpose of obtaining  or  preserving  the full  benefits of this
Agreement  and of the rights  and  powers  herein  granted,  including,  without
limitation,  the filing of any financing or  continuation  statements  under the
Uniform  Commercial  Code (or other similar laws) in effect in any  jurisdiction
with respect to the security interests created hereby.

                  5.4 Changes in  Locations,  Name,  etc. Such Grantor will not,
except upon 15 days' prior written notice to the  Collateral  Agent and delivery
to the Collateral Agent of (a) all additional executed financing  statements and
other  documents  reasonably  requested by the Collateral  Agent to maintain the
validity,  perfection and priority of the security interests provided for herein
and (b) if applicable, a written supplement to Schedule 5 showing any additional
location at which Inventory or Equipment shall be kept:

                  (i)  permit  any of the  Inventory  or  Equipment  in  which a
         security interest is required to be perfected by Section 3.2 to be kept
         at a location other than those listed on Schedule 5;

                  (ii) change the location of its chief executive office or sole
         place of business from that referred to in Section 4.6; or

                  (iii) change its name, identity or corporate structure to such
         an extent that any financing statement filed by the Collateral Agent in
         connection with this Agreement would become misleading.

                  5.5 Notices. Such Grantor will advise the Collateral Agent and
the Secured  Parties  promptly,  in reasonable  detail,  of any Lien (other than
security   interests  created  hereby  or  Liens  permitted  under  the  Secured
Instruments) on any of the material Collateral which would materially  adversely
affect the  ability of the  Collateral  Agent to  exercise  any of its  remedies
hereunder.

                  5.6  Pledged  Securities.  (a) If such  Grantor  shall  become
entitled to receive or shall receive any stock certificate  (including,  without
limitation,  any certificate  representing a stock dividend or a distribution in
connection  with any  reclassification,  increase or reduction of capital or any
certificate issued in connection with any  reorganization),  option or rights in
respect  of the  Capital  Stock  of any  Issuer,  whether  in  addition  to,  in
substitution  of, as a  conversion  of, or in  exchange  for,  any shares of the
Pledged Stock, or otherwise in respect thereof, such Grantor

                                                                              18



shall  accept  the same as the agent of the  Collateral  Agent  and the  Secured
Parties, hold the same in trust for the Collateral Agent and the Secured Parties
and  deliver  the same  forthwith  to the  Collateral  Agent in the  exact  form
received,  duly indorsed by such Grantor to the Collateral  Agent,  if required,
together with an undated stock power covering such  certificate duly executed in
blank by such Grantor and with, if the Collateral  Agent so requests,  signature
guaranteed,  to be held by the Collateral Agent, subject to the terms hereof, as
additional collateral security for the Obligations and the same shall constitute
"Pledged Stock" for purpose of this Agreement.  Any sums paid upon or in respect
of the Pledged  Securities  upon the  liquidation  or  dissolution of any Issuer
shall  be paid  over to the  Collateral  Agent  to be  held by it  hereunder  as
additional collateral security for the Obligations, and in case any distribution
of  capital  shall be made on or in  respect of the  Pledged  Securities  or any
property  shall be  distributed  upon or with respect to the Pledged  Securities
pursuant  to the  recapitalization  or  reclassification  of the  capital of any
Issuer or pursuant to the  reorganization  thereof,  the property so distributed
shall, unless otherwise subject to a perfected security interest in favor of the
Collateral  Agent,  be  delivered  to the  Collateral  Agent  to be  held  by it
hereunder as additional collateral security for the Obligations.  If any sums of
money or property so paid or  distributed  in respect of the Pledged  Securities
shall be received  by such  Grantor,  such  Grantor  shall,  until such money or
property  is paid or  delivered  to the  Collateral  Agent,  hold such  money or
property in trust for the Secured  Parties,  segregated from other funds of such
Grantor, as additional collateral security for the Obligations.

                  (b) Without the prior written consent of the Collateral Agent,
such  Grantor  will not (i) vote to enable,  or take any other action to permit,
any  Issuer to issue any stock or other  equity  securities  of any nature or to
issue any other securities convertible into or granting the right to purchase or
exchange for any stock or other equity  securities  of any nature of any Issuer,
(ii) sell,  assign,  transfer,  exchange,  or otherwise dispose of, or grant any
option with  respect  to, the Pledged  Securities  or Proceeds  thereof  (except
pursuant to a transaction expressly permitted by the Secured Instruments), (iii)
create, incur or permit to exist any Lien or option in favor of, or any claim of
any Person with respect to, any of the Pledged  Securities or Proceeds  thereof,
or any  interest  therein,  except for the  security  interests  created by this
Agreement or (iv) enter into any agreement or undertaking  restricting the right
or ability of such Grantor or the Collateral  Agent to sell,  assign or transfer
any of the Pledged Securities or Proceeds thereof.

                  (c) In the  case of each  Grantor  which  is an  Issuer,  such
Issuer agrees that (i) it will be bound by the terms of this Agreement  relating
to the Pledged  Securities  issued by it and will comply with such terms insofar
as such terms are  applicable  to it, (ii) it will notify the  Collateral  Agent
promptly in writing of the occurrence of any of the events  described in Section
5.8(a) with respect to the Pledged  Securities  issued by it and (iii) the terms
of Sections 6.3(c) and 6.7 shall apply to it, mutatis mutandis,  with respect to
all actions  that may be  required of it pursuant to Section  6.3(c) or 6.7 with
respect to the Pledged Securities issued by it.

                  5.7  Receivables.   Other  than  in  the  ordinary  course  of
business,  such Grantor will not (i) grant any  extension of the time of payment
of any material  Receivable,  (ii) compromise or settle any material  Receivable
for less than the full amount thereof, (iii) release, wholly or



<PAGE>


                                                                              19



partially,  any Person liable for the payment of any material  Receivable,  (iv)
allow  any  credit  or  discount  whatsoever  on any  Receivable  or (v)  amend,
supplement or modify any material  Receivable in any manner that could adversely
affect the value thereof.

                  5.8 Intellectual  Property. (a) Such Grantor (either itself or
through licensees) will (i) continue to use each material  Trademark  adequately
and  sufficiently  so as 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) use such  Trademark
with the appropriate  notice of  registration  and all other notices and legends
required by applicable Requirements of Law, (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 Secured Parties, shall obtain a
perfected security interest in such mark pursuant to this Agreement, and (v) not
(and not knowingly permit any licensee or sublicensee  thereof to) do any act or
knowingly  omit to do any act whereby such  Trademark may become  invalidated or
impaired  in any way,  except,  in each case,  where the failure to do so is not
reasonably expected to have a Material Adverse Effect.

                  (b) Such Grantor (either itself or through licensees) will not
do any act,  or omit to do any act,  whereby  any  material  Patent  may  become
forfeited,  abandoned or dedicated  to the public,  except those not  reasonably
expected to have a Material Adverse Effect.

                  (c) Such Grantor (either itself or through licensees) (i) will
employ each material Copyright, except where the failure to do is not reasonably
expected  to have a  Material  Adverse  Effect  and (ii)  will not (and will not
permit any licensee or  sublicensee  thereof to) do any act or knowingly omit to
do any act whereby any material portion of the Copyrights may become invalidated
or otherwise  impaired,  except those not reasonably expected to have a Material
Adverse  Effect.  Such  Grantor  will not (either  itself or through  licensees)
knowingly do any act whereby any  material  portion of the  Copyrights  may fall
into the public domain,  except those not reasonably expected to have a Material
Adverse Effect.


                  (d) Such Grantor (either itself or through licensees) will not
do any act that  knowingly uses any material  Intellectual  Property to infringe
the  intellectual  property  rights  of  any  other  Person,  except  those  not
reasonably expected to have a Material Adverse Effect.

                  (e) Such  Grantor  will  notify the  Collateral  Agent and the
Secured  Parties  immediately  if it  knows,  or has  reason  to know,  that any
application or registration  relating to any material  Intellectual Property may
become  forfeited,  abandoned  or  dedicated  to the  public,  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,  the United States Copyright Office or any court or
tribunal  in any  country)  (except  for  routine  "office  actions",  excluding
objections based on 15 USC ss.1052(d)) regarding such Grantor's ownership of, or
the validity of, any material  Intellectual  Property or such Grantor's right to
register the same or to own and maintain the same.

                  (f)  Whenever  such  Grantor,  either by itself or through any
agent,  employee,  licensee  or  designee,  shall  file an  application  for the
registration  of any  Intellectual  Property  with the United  States Patent and
Trademark  Office,  the United States  Copyright 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 30 days after the last
day of the fiscal  quarter  in which such  filing  occurs.  Upon  request of the
Collateral Agent, such Grantor shall execute and deliver, and have recorded, any
and all agreements,  instruments,  documents, and papers as the Collateral Agent
may request to evidence the Secured Parties' security interest in any Copyright,
Patent or Trademark  and the goodwill  and general  intangibles  of such Grantor
relating thereto or represented thereby.

                  (g) Such Grantor will take all reasonable and necessary steps,
including, without limitation, in any proceeding before the United States Patent
and Trademark  Office,  the United States Copyright 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 the material  Intellectual  Property,  including,
without  limitation,  filing of applications for renewal,  affidavits of use and
affidavits  of  incontestability,  except  where the  failure to do so could not
reasonably be expected to have a material adverse effect.

                  (h) In the event that any  material  Intellectual  Property is
infringed,  misappropriated  or diluted by a third party, such Grantor shall (i)
take such actions as such Grantor shall  reasonably deem  appropriate  under the
circumstances to protect such Intellectual Property, except where the failure to
do so could not  reasonably  be expected to have a material  adverse  effect and
(ii) if such  Intellectual  Property is of  material  economic  value,  promptly
notify the Collateral  Agent after it learns  thereof and sue for  infringement,
misappropriation or dilution, to seek injunctive relief where appropriate and to
recover any and all damages for such infringement, misappropriation or dilution.


                         SECTION 6. REMEDIAL PROVISIONS

                  6.1 Certain Matters  Relating to Receivables.  (a) If an Event
of Default shall have occurred and be  continuing,  the  Collateral  Agent shall
have the right to make test  verifications  of the Receivables in any manner and
through any medium that it  reasonably  considers  advisable,  and each  Grantor
shall furnish all such  assistance and  information as the Collateral  Agent may
require in connection with such test verifications. At any time and from time to
time (in any  event,  not more than once  during any 365 day  period),  upon the
Collateral  Agent's  reasonable  request  and at  the  expense  of the  relevant
Grantor,  such Grantor  shall cause  independent  public  accountants  or others
satisfactory to the Collateral  Agent to furnish to the Collateral Agent reports
showing  reconciliations,  aging and test  verifications  of, and trial balances
for, the Receivables.

                                                                              21



                  (b) The  Collateral  Agent hereby  authorizes  each Grantor to
collect  such  Grantor's  Receivables  and the  Collateral  Agent may curtail or
terminate  said authority at any time when a Notice of Enforcement is in effect.
If required by the Collateral  Agent at any time when a Notice of Enforcement is
in effect, any payments of Receivables, when collected by any Grantor, (i) shall
be forthwith  (and, in any event,  within two Business  Days)  deposited by such
Grantor  in the exact  form  received,  duly  indorsed  by such  Grantor  to the
Collateral Agent if required,  in a Collateral Account maintained under the sole
dominion  and control of the  Collateral  Agent,  subject to  withdrawal  by the
Collateral  Agent for the  account of the  Secured  Parties  only as provided in
Section  6.5,  and (ii) until so turned  over,  shall be held by such Grantor in
trust for the Secured Parties, segregated from other funds of such Grantor. Each
such  deposit  of  Proceeds  of  Receivables  shall be  accompanied  by a report
identifying in reasonable  detail the nature and source of the payments included
in the deposit.

                  (c)  If an  Event  of  Default  shall  have  occurred  and  be
continuing, at the Collateral Agent's request, each Grantor shall deliver to the
Collateral Agent all original and other documents  evidencing,  and relating to,
the agreements and transactions  which gave rise to the Receivables,  including,
without limitation, all original orders, invoices and shipping receipts.

                  6.2 Communications with Obligors;  Grantors Remain Liable. (a)
At any time when a Notice of Enforcement is in effect,  the Collateral  Agent in
its own name or in the name of others may at any time  communicate with obligors
under the Receivables to verify with them to the Collateral Agent's satisfaction
the existence, amount and terms of any Receivables.

                  (b) Upon the request of the Collateral  Agent at any time when
a Notice of Enforcement is in effect,  each Grantor shall notify obligors on the
Receivables  that the Receivables have been assigned to the Collateral Agent for
the ratable  benefit of the Secured Parties and that payments in respect thereof
shall be made directly to the Collateral Agent.

                  (c)  Anything  herein to the  contrary  notwithstanding,  each
Grantor shall remain liable under each of the Receivables to observe and perform
all  the  conditions  and  obligations  to  be  observed  and  performed  by  it
thereunder,  all in  accordance  with the  terms of any  agreement  giving  rise
thereto.  Neither  the  Collateral  Agent nor any  Secured  Party shall have any
obligation  or liability  under any  Receivable  (or any  agreement  giving rise
thereto)  by reason of or arising  out of this  Agreement  or the receipt by the
Collateral Agent or any Secured Party of any payment relating thereto, nor shall
the Collateral  Agent or any Secured Party be obligated in any manner to perform
any of the  obligations  of any Grantor under or pursuant to any  Receivable (or
any agreement giving rise thereto),  to make any payment, to make any inquiry as
to the nature or the  sufficiency  of any  payment  received  by it or as to the
sufficiency of any performance by any party  thereunder,  to present or file any
claim,  to take any action to enforce any  performance or to collect the payment
of any amounts which may have been assigned to it or to which it may be entitled
at any time or times.

                  6.3  Certain Matters Relating to Pledged Stock.  (a)  Unless a
Notice of  Enforcement  is in effect and the  Collateral  Agent shall have given
notice to the relevant Grantor

of the Collateral  Agent's intent to exercise its corresponding  rights pursuant
to Section 6.3(b), each Grantor shall be permitted to receive all cash dividends
paid in respect of the  Pledged  Stock and all  payments  made in respect of the
Pledged  Notes,  in each  case paid in the  normal  course  of  business  of the
relevant Issuer to the extent not prohibited by any Secured  Instrument,  and to
exercise all voting and corporate rights with respect to the Pledged Securities;
provided,  however,  that no vote shall be cast or corporate  right exercised or
other action taken which impairs the  Collateral or which would be  inconsistent
with or result in any violation of any provision of this Agreement, any Security
Document or any other Secured Instrument.

                  (b) If a Notice of Enforcement is in effect and the Collateral
Agent  shall have  given  notice of its intent to  exercise  such  rights to the
relevant  Grantor or Grantors,  (i) the Collateral Agent shall have the right to
receive any and all cash  dividends,  payments or other Proceeds paid in respect
of the Pledged Securities and make application thereof to the Obligations in the
order set forth in Section  6.5,  and (ii) any or all of the Pledged  Securities
shall be registered in the name of the Collateral Agent or its nominee,  and the
Collateral  Agent  or its  nominee  may  thereafter  exercise  (x)  all  voting,
corporate and other rights pertaining to such Pledged  Securities at any meeting
of  shareholders  of the relevant Issuer or Issuers or otherwise and (y) any and
all  rights of  conversion,  exchange  and  subscription  and any other  rights,
privileges or options  pertaining  to such Pledged  Securities as if it were the
absolute owner thereof (including,  without limitation, the right to exchange at
its  discretion  any  and  all  of  the  Pledged  Securities  upon  the  merger,
consolidation,  reorganization,  recapitalization or other fundamental change in
the  corporate  structure of any Issuer,  or upon the exercise by any Grantor or
the  Collateral  Agent of any  right,  privilege  or option  pertaining  to such
Pledged  Securities,  and in  connection  therewith,  the right to  deposit  and
deliver any and all of the Pledged  Securities  with any committee,  depositary,
transfer  agent,  registrar  or other  designated  agency  upon  such  terms and
conditions as the Collateral Agent may determine),  all without liability except
to account for property  actually received by it, but the Collateral Agent shall
have no duty to any Grantor to exercise any such right,  privilege or option and
shall not be responsible for any failure to do so or delay in so doing.

                  (c) Each Grantor  hereby  authorizes and instructs each Issuer
of any Pledged  Securities  pledged by such Grantor hereunder to (i) comply with
any  instruction  received by it from the  Collateral  Agent in writing that (x)
states  that a Notice  of  Enforcement  is in  effect  and (y) is  otherwise  in
accordance  with the  terms of this  Agreement,  without  any  other or  further
instructions  from such Grantor,  and each Grantor agrees that each Issuer shall
be  fully  protected  in so  complying,  and  (ii)  unless  otherwise  expressly
permitted  hereby,  pay any  dividends  or other  payments  with  respect to the
Pledged Securities directly to the Collateral Agent.

                  6.4  Proceeds  to be  Turned  Over  To  Collateral  Agent.  In
addition  to the rights of the  Secured  Parties  specified  in Section 6.1 with
respect to payments of Receivables,  if a Notice of Enforcement is in effect and
the  Collateral  Agent shall have given  notice of its intent to  exercise  such
rights to the relevant Grantor or Grantors, all Proceeds received by any Grantor
consisting  of cash,  checks  and other  near-cash  items  shall be held by such
Grantor in trust for the Secured  Parties,  segregated  from other funds of such
Grantor, and shall, forthwith upon receipt

                                                                              23



by such  Grantor,  be turned  over to the  Collateral  Agent in the  exact  form
received by such Grantor (duly indorsed by such Grantor to the Collateral Agent,
if required).  All Proceeds  received by the Collateral Agent hereunder shall be
held by the Collateral Agent in a Collateral  Account  maintained under its sole
dominion  and  control.  All Proceeds  while held by the  Collateral  Agent in a
Collateral  Account (or by such Grantor in trust for the Secured  Parties) shall
continue to be held as collateral security for all the Obligations and shall not
constitute payment thereof until applied as provided in Section 6.5.

                  6.5 Application of Proceeds.  The Collateral Agent shall apply
all Proceeds constituting Collateral and all proceeds of the guarantee set forth
in Section 2 in the manner  required by subsection 3.4 of the Collateral  Agency
and Intercreditor Agreement.

                  6.6 Code and Other Remedies.  If a Notice of Enforcement is in
effect, the Collateral Agent, on behalf of the Secured Parties, may exercise, in
addition to all other rights and remedies  granted to them in this Agreement and
in any other  instrument  or agreement  securing,  evidencing or relating to the
Obligations,  all rights and remedies of a secured  party under the New York UCC
or any other  applicable law.  Without limiting the generality of the foregoing,
to the extent permitted by applicable law, the Collateral Agent,  without demand
of performance or other demand, presentment, protest, advertisement or notice of
any kind  (except any notice  required by law  referred to below) to or upon any
Grantor or any other Person to the extent  permitted by applicable  law (all and
each of which demands, defenses,  advertisements and notices are hereby waived),
may in such circumstances  forthwith collect,  receive,  appropriate and realize
upon the  Collateral,  or any part thereof,  and/or may forthwith  sell,  lease,
assign, give option or options to purchase,  or otherwise dispose of and deliver
the Collateral or any part thereof (or contract to do any of the foregoing),  in
one or more  parcels  at  public or  private  sale or  sales,  at any  exchange,
broker's  board  or  office  of the  Collateral  Agent or any  Secured  Party or
elsewhere  upon such terms and  conditions as it may deem  advisable and at such
prices as it may deem best, for cash or on credit or for future delivery without
assumption of any credit risk. The  Collateral  Agent or any Secured Party shall
have the right upon any such public sale or sales,  and, to the extent permitted
by law,  upon any such private sale or sales,  to purchase the whole or any part
of the  Collateral  so sold,  free of any right or equity of  redemption  in any
Grantor,  which  right or equity is hereby  waived and  released.  Each  Grantor
further agrees,  at the Collateral  Agent's request,  to assemble the Collateral
and make it available  to the  Collateral  Agent at places which the  Collateral
Agent shall reasonably  select whether at such Grantor's  premises or elsewhere.
The  Collateral  Agent  shall apply the net  proceeds of any action  taken by it
pursuant to this Section 6.6, after deducting all reasonable  costs and expenses
of every kind  incurred in  connection  therewith or  incidental  to the care or
safekeeping of any of the Collateral or in any way relating to the Collateral or
the rights of the Secured  Parties  hereunder,  including,  without  limitation,
reasonable attorneys' fees and disbursements, to the payment in whole or in part
of the Obligations,  in the manner specified in subsection 3.4 of the Collateral
Agency and  Intercreditor  Agreement,  and only after such application and after
the  payment  by the  Collateral  Agent  of any  other  amount  required  by any
provision of law, including, without limitation,  Section 9-504(1)(c) of the New
York UCC,  need the  Collateral  Agent  account for the surplus,  if any, to any
Grantor.  To the extent  permitted by applicable  law,  each Grantor  waives all
claims, damages and demands



<PAGE>


                                                                              24



it may acquire against the Collateral  Agent or any Secured Party arising out of
the exercise by them of any rights  hereunder.  If any notice of a proposed sale
or other  disposition of Collateral  shall be required by law, such notice shall
be deemed  reasonable  and proper if given at least 10 days  before such sale or
other disposition.

                  6.7  Registration  Rights.  (a) If the Collateral  Agent shall
determine to exercise its right to sell any or all of the Pledged Stock pursuant
to Section 6.6, and if in the opinion of the Collateral Agent it is necessary or
advisable  to have  the  Pledged  Stock,  or that  portion  thereof  to be sold,
registered under the provisions of the Securities Act, the relevant Grantor will
cause the Issuer thereof to (i) execute and deliver, and cause the directors and
officers  of such  Issuer to  execute  and  deliver,  all such  instruments  and
documents,  and do or cause to be done all  such  other  acts as may be,  in the
opinion of the Collateral Agent,  necessary or advisable to register the Pledged
Stock,  or  that  portion  thereof  to be  sold,  under  the  provisions  of the
Securities  Act, (ii) use its best efforts to cause the  registration  statement
relating thereto to become effective and to remain effective for a period of one
year from the date of the first public  offering of the Pledged  Stock,  or that
portion thereof to be sold, and (iii) make all amendments  thereto and/or to the
related  prospectus which, in the opinion of the Collateral Agent, are necessary
or advisable,  all in conformity with the requirements of the Securities Act and
the rules and regulations of the Securities and Exchange  Commission  applicable
thereto.  Each Grantor agrees to cause such Issuer to comply with the provisions
of the  securities  or "Blue  Sky" laws of any and all  jurisdictions  which the
Collateral Agent shall designate and to make available to its security  holders,
as soon as practicable,  an earnings statement (which need not be audited) which
will satisfy the provisions of Section 11(a) of the Securities Act.

                  (b) Each Grantor  recognizes that the Collateral  Agent may be
unable to effect a public  sale of any or all the  Pledged  Stock,  by reason of
certain  prohibitions  contained  in the  Securities  Act and  applicable  state
securities  laws or  otherwise,  and may be  compelled  to resort to one or more
private sales thereof to a restricted  group of purchasers which will be obliged
to agree,  among other things,  to acquire such securities for their own account
for investment and not with a view to the  distribution or resale thereof.  Each
Grantor  acknowledges and agrees that any such private sale may result in prices
and  other  terms  less  favorable  than if such  sale  were a public  sale and,
notwithstanding  such circumstances,  agrees that any such private sale shall be
deemed to have been made in a  commercially  reasonable  manner.  The Collateral
Agent shall be under no  obligation  to delay a sale of any of the Pledged Stock
for the period of time  necessary to permit the Issuer  thereof to register such
securities for public sale under the Securities Act, or under  applicable  state
securities laws, even if such Issuer would agree to do so.

                  (c) Each Grantor agrees to use its best efforts to do or cause
to be done all such other acts as may be necessary to make such sale or sales of
all or any portion of the Pledged  Stock  pursuant to this Section 6.7 valid and
binding and in compliance with any and all other applicable Requirements of Law.
Each Grantor  further agrees that a breach of any of the covenants  contained in
this Section 6.7 will cause irreparable injury to the Secured Parties,  that the
Secured Parties have no adequate remedy at law in respect of such breach and, as
a consequence,  that each and every covenant contained in this Section 6.7 shall
be specifically



<PAGE>


                                                                              25



enforceable against such Grantor,  and such Grantor hereby waives and agrees not
to assert  any  defenses  against  an action for  specific  performance  of such
covenants.

                  6.8 Approvals.  Any provision contained herein to the contrary
notwithstanding,  no action shall be taken hereunder by the Collateral  Agent or
any Secured Party with respect to any  Collateral in the form of FCC Licenses or
the Pledged Stock of any Issuer that holds any FCC License  unless and until all
applicable  requirements  of the FCC,  if any,  under  the  Communications  Act,
applicable  state laws and the respective  rules and regulations  thereunder and
thereof,  as  well  as any  other  laws,  rules  and  regulations  of any  other
Governmental Authority applicable to or having jurisdiction over the Borrower or
the  relevant  Grantor  or  Issuer,  have  in  the  reasonable  judgment  of the
Collateral  Agent been fully  satisfied  to the  extent  necessary  to take such
action and there have been obtained such consents, approvals and authorizations,
as may be  required  to be  obtained  from the FCC,  applicable  state and local
regulatory  authorities and municipalities and any other Governmental  Authority
under the terms of any franchise, license or similar operating right held by the
Borrower or the relevant  Grantor or Issuer in order to take such action.  It is
the intention of the parties  hereto that the pledge in favor of the  Collateral
Agent of the  Pledged  Stock of any Issuer that holds any FCC  License,  and the
creation of a security interest (to the extent permitted by law) in favor of the
Collateral Agent in FCC Licenses,  and all rights and remedies by the Collateral
Agent with respect to such Pledged Stock and FCC Licenses, shall in all relevant
aspects be subject to and governed by said statutes,  rules and  regulations and
that  nothing in this  Agreement  shall be  construed  to  diminish  the control
exercised  by  the  Borrower  or the  relevant  Grantor  or  Issuer,  except  in
accordance  with the  provisions of such  statutory  requirements  and rules and
regulations.  By its acceptance of this Agreement,  the Collateral  Agent agrees
that the  Collateral  Agent will not take any action  pursuant to this Agreement
which  constitutes or results in any assignment of a license or franchise or any
change of control over the  communications  properties owned and operated by any
Grantor,  if such assignment of license or franchise or change of control would,
under then existing law or under any franchise,  require the prior approval of a
Governmental Authority, without first obtaining such approval. Upon the exercise
by the Collateral  Agent of any power,  right,  privilege or remedy  pursuant to
this Agreement which requires any consent, approval, recording, qualification or
authorization  of any  Governmental  Authority,  the  Borrower  or the  relevant
Grantor or Issuer will  execute and  deliver,  or will cause the  execution  and
delivery of, all applications, certificates, instruments and other documents and
papers  that the  Collateral  Agent  may  reasonably  require  in order for such
governmental consent, approval, recording,  qualification or authorization to be
obtained. The Borrower agrees to use its best efforts to cause such governmental
consents,  approvals,  recordings,   qualifications  and  authorizations  to  be
forthcoming.

                  6.9 Waiver; Deficiency.  Each Grantor waives and agrees not to
assert  any  rights or  privileges  against  the  Collateral  Agent or any other
secured party which it may acquire under Section 9-112 of the New York UCC. Each
Grantor  shall remain  liable for any  deficiency if the proceeds of any sale or
other  disposition  of the Collateral are  insufficient  to pay its  Obligations
subject  to  Section  2.1(b)  and the fees and  disbursements  of any  attorneys
employed  by  the  Collateral  Agent  or  any  Secured  Party  to  collect  such
deficiency.

                                                                              26



                  6.10 Issuers.  Each Grantor which is an Issuer agrees,  in its
capacity as an Issuer of Pledged  Stock,  to comply with the  provisions of this
Agreement to the extent relating to such Pledged Stock. Each Grantor which is an
Issuer and a limited liability company or a partnership  agrees, in its capacity
as Issuer of Pledged Stock,  that if such Pledged Stock shall at any time become
a "security" within the meaning of Section 8-102 of the New York UCC such Issuer
will (i) if such securities are "certificated  securities" within the meaning of
Section  8-102 of the New York UCC,  deliver  such  certificates,  or cause such
certificates  to be  delivered  only to the  Collateral  Agent on  behalf of the
Grantor and not to any Grantor and (ii) if such  securities are  "uncertificated
securities" within the meaning of Section 8-102 of the New York UCC, comply with
instructions  originated by the Collateral  Agent in respect of such  securities
without  further  consent by the Grantor in respect  thereof;  and each  Grantor
instructs each such Issuer to comply with the foregoing agreements.


                         SECTION 7. THE COLLATERAL AGENT

                  7.1 Collateral Agent's Appointment as  Attorney-in-Fact,  etc.
(a) Each Grantor  hereby  irrevocably  constitutes  and appoints the  Collateral
Agent and any officer or agent thereof, with full power of substitution,  as its
true and lawful  attorney-in-fact  with full irrevocable  power and authority in
the place and stead of such  Grantor  and in the name of such  Grantor or in its
own name, for the purpose of carrying out the terms of this  Agreement,  to take
any and all  appropriate  action  and to  execute  any  and  all  documents  and
instruments  which may be necessary or desirable to  accomplish  the purposes of
this  Agreement,  and,  without  limiting the generality of the foregoing,  each
Grantor hereby gives the Collateral Agent the power and right, on behalf of such
Grantor,  without  notice to or assent by such Grantor,  to do any or all of the
following:

                  (i) in the name of such Grantor or its own name, or otherwise,
         take possession of and indorse and collect any checks,  drafts,  notes,
         acceptances  or other  instruments  for the payment of moneys due under
         any  Receivable  or with respect to any other  Collateral  and file any
         claim or take any  other  action or  proceeding  in any court of law or
         equity or otherwise deemed  appropriate by the Collateral Agent for the
         purpose of collecting  any and all such moneys due under any Receivable
         or with respect to any other Collateral whenever payable;

                  (ii) in the case of any  Intellectual  Property,  execute  and
         deliver,  and  have  recorded,  any  and all  agreements,  instruments,
         documents  and papers as the  Collateral  Agent may request to evidence
         the Secured Parties' security  interest in such  Intellectual  Property
         and the  goodwill  and general  intangibles  of such  Grantor  relating
         thereto or represented thereby;

                  (iii) pay or discharge  taxes and Liens levied or placed on or
         threatened against the Collateral,  effect any repairs or any insurance
         called  for by the terms of this  Agreement  and pay all or any part of
         the premiums therefor and the costs thereof;



<PAGE>


                                                                              27



                  (iv)  execute,  in  connection  with any sale  provided for in
         Section 6.6 or 6.7, any indorsements,  assignments or other instruments
         of conveyance or transfer with respect to the Collateral; and

                  (v) (1) direct any party  liable for any payment  under any of
         the  Collateral  to make payment of any and all moneys due or to become
         due thereunder  directly to the  Collateral  Agent or as the Collateral
         Agent shall direct; (2) ask or demand for, collect, and receive payment
         of and receipt for, any and all moneys, claims and other amounts due or
         to  become  due  at  any  time  in  respect  of or  arising  out of any
         Collateral;  (3) sign and  indorse  any  invoices,  freight  or express
         bills, bills of lading,  storage or warehouse receipts,  drafts against
         debtors,  assignments,  verifications,  notices and other  documents in
         connection with any of the  Collateral;  (4) commence and prosecute any
         suits,  actions  or  proceedings  at law or in  equity  in any court of
         competent jurisdiction to collect the Collateral or any portion thereof
         and to enforce any other right in respect of any Collateral; (5) defend
         any suit,  action or  proceeding  brought  against  such  Grantor  with
         respect to any  Collateral;  (6) settle,  compromise or adjust any such
         suit,  action or  proceeding  and, in connection  therewith,  give such
         discharges or releases as the  Collateral  Agent may deem  appropriate;
         (7) assign any Copyright,  Patent or Trademark (along with the goodwill
         of the  business  to which  any such  Copyright,  Patent  or  Trademark
         pertains),  throughout  the  world  for  such  term or  terms,  on such
         conditions,  and in such manner,  as the Collateral  Agent shall in its
         sole discretion determine;  and (8) generally,  sell, transfer,  pledge
         and make any  agreement  with respect to or otherwise  deal with any of
         the Collateral as fully and  completely as though the Collateral  Agent
         were the  absolute  owner  thereof  for all  purposes,  and do,  at the
         Collateral Agent's option and such Grantor's  expense,  at any time, or
         from time to time, all acts and things which the Collateral Agent deems
         necessary to protect,  preserve or realize upon the  Collateral and the
         Secured parties' security interests therein and to effect the intent of
         this Agreement, all as fully and effectively as such Grantor might do.

         Anything in this Section  7.1(a) to the contrary  notwithstanding,  the
Collateral  Agent agrees that it will not exercise any rights under the power of
attorney  provided for in this Section  7.1(a) unless a Notice of Enforcement is
in effect.

                  (b) If any Grantor  fails to perform or comply with any of its
agreements  contained herein,  the Collateral Agent, at its option,  but without
any obligation so to do, may perform or comply,  or otherwise cause  performance
or compliance, with such agreement.

                  (c)  The  expenses  of  the   Collateral   Agent  incurred  in
connection  with actions  undertaken  as provided in this Section 7.1,  together
with  interest  thereon at a rate per annum equal to the rate per annum at which
interest  would then be payable on past due Revolving  Credit Loans that are ABR
Loans under (and as defined in) the Credit  Agreement,  from the date of payment
by the Collateral Agent to the date reimbursed by the relevant Grantor, shall be
payable by such Grantor to the Collateral Agent on demand.

                                                                              28



                  (d) Each Grantor hereby ratifies all that said attorneys shall
lawfully do or cause to be done by virtue hereof. All powers, authorizations and
agencies  contained  in this  Agreement  are coupled  with an  interest  and are
irrevocable  until this  Agreement  is  terminated  and the  security  interests
created hereby are released.

                  7.2 Duty of Collateral Agent. The Collateral Agent's sole duty
with  respect to the  custody,  safekeeping  and  physical  preservation  of the
Collateral  in its  possession,  under  Section  9-207  of the New  York  UCC or
otherwise,  shall be to deal with it in the same manner as the Collateral  Agent
deals with similar property for its own account.  Neither the Collateral  Agent,
any Secured Party nor any of their respective officers, directors,  employees or
agents shall be liable for failure to demand, collect or realize upon any of the
Collateral or for any delay in doing so or shall be under any obligation to sell
or otherwise  dispose of any  Collateral  upon the request of any Grantor or any
other  Person  or to  take  any  other  action  whatsoever  with  regard  to the
Collateral or any part thereof. The powers conferred on the Collateral Agent and
the  Secured  Parties  hereunder  are solely to  protect  the  Secured  Parties'
interests in the  Collateral  and shall not impose any duty upon the  Collateral
Agent or any Secured Party to exercise any such powers. The Collateral Agent and
the Secured  Parties  shall be  accountable  only for amounts that they actually
receive as a result of the exercise of such powers,  and neither they nor any of
their  officers,  directors,  employees  or agents shall be  responsible  to any
Grantor  for any act or  failure  to act  hereunder,  except for their own gross
negligence or willful misconduct.

                  7.3  Execution  of Financing  Statements.  Pursuant to Section
9-402 of the New York UCC and any other applicable law, each Grantor  authorizes
the Collateral Agent to file or record financing  statements and other filing or
recording  documents or instruments  with respect to the Collateral  without the
signature  of such  Grantor in such form and in such  offices as the  Collateral
Agent reasonably determines appropriate to perfect the security interests of the
Collateral Agent under this Agreement, to the extent such security interests are
required  to be  perfected  pursuant  to Section  3.2. A  photographic  or other
reproduction of this Agreement  shall be sufficient as a financing  statement or
other filing or recording  document or instrument for filing or recording in any
jurisdiction.

                  7.4 Authority of Collateral Agent.  Each Grantor  acknowledges
that  the  rights  and  responsibilities  of the  Collateral  Agent  under  this
Agreement  with  respect  to any  action  taken by the  Collateral  Agent or the
exercise or  non-exercise by the Collateral  Agent of any option,  voting right,
request,  judgment or other right or remedy  provided for herein or resulting or
arising out of this Agreement  shall,  as between the  Collateral  Agent and the
Secured  Parties,  be  governed  by  the  Collateral  Agency  and  Intercreditor
Agreement and by such other  agreements  with respect  thereto as may exist from
time to time among them, but, as between the Collateral  Agent and the Grantors,
the Collateral  Agent shall be  conclusively  presumed to be acting as agent for
the Secured  Parties  with full and valid  authority  so to act or refrain  from
acting,  and no Grantor shall be under any obligation,  or entitlement,  to make
any inquiry respecting such authority.

                            SECTION 8. MISCELLANEOUS

                  8.1 Amendments in Writing.  None of the terms or provisions of
this Agreement may be waived, amended, supplemented or otherwise modified except
in  accordance  with  Section  8.3 of the  Collateral  Agency and  Intercreditor
Agreement.

                  8.2 Notices. All notices,  requests and demands to or upon the
Collateral  Agent or any  Grantor  hereunder  shall be  effected  in the  manner
provided  for  in  Section  8.1  of  the  Collateral  Agency  and  Intercreditor
Agreement;  provided  that any such  notice,  request  or  demand to or upon any
Guarantor  shall be addressed to such  Guarantor at its notice address set forth
on Schedule 1.

                  8.3 No  Waiver  by Course  of  Conduct;  Cumulative  Remedies;
Limitation by Law. (a) Neither the Collateral  Agent nor any Secured Party shall
by any act  (except by a written  instrument  pursuant to Section  8.1),  delay,
indulgence,  omission or  otherwise be deemed to have waived any right or remedy
hereunder or to have acquiesced in any default by the Borrower under any Secured
Instrument.  No failure to exercise, nor any delay in exercising, on the part of
the  Collateral  Agent or any  Secured  Party,  any  right,  power or  privilege
hereunder  shall operate as a waiver thereof.  No single or partial  exercise of
any right,  power or  privilege  hereunder  shall  preclude any other or further
exercise  thereof or the  exercise of any other  right,  power or  privilege.  A
waiver  by the  Collateral  Agent or any  Secured  Party of any  right or remedy
hereunder  on any one  occasion  shall not be construed as a bar to any right or
remedy which the Collateral  Agent or such Secured Party would otherwise have on
any future occasion. The rights and remedies herein provided are cumulative, may
be exercised singly or concurrently and are not exclusive of any other rights or
remedies provided by law.

                  (b) All  rights,  remedies,  and  powers  provided  under this
Agreement may be exercised only to the extent that the exercise thereof does not
violate any  applicable  provision  of law,  and all the  provisions  under this
Agreement are intended to be subject to all applicable  mandatory  provisions of
law which may be  controlling  and (subject to Section 8.8) to be limited to the
extent  necessary  so  that  they  will  not  render  this  Agreement   invalid,
unenforceable in whole or in part or not entitled to be recorded,  registered or
filed under the provisions of any applicable law.

                  8.4 Enforcement Expenses; Indemnification.  (a) Each Guarantor
agrees to pay or reimburse each Secured Party and the  Collateral  Agent for all
its costs and expenses  incurred in collecting  against such Guarantor under the
guarantee contained in Section 2 or otherwise enforcing or preserving any rights
under this Agreement and the other Security Documents to which such Guarantor is
a party,  including,  without limitation,  the fees and disbursements of counsel
(including the allocated fees and expenses of in-house  counsel) to each Secured
Party and of counsel to the Collateral Agent.

                  (b) The agreements in this Section shall survive  repayment of
the  Secured  Obligations  and all  other  amounts  payable  under  the  Secured
Instruments.

                  8.5  Successors and Assigns.  This Agreement  shall be binding
upon the  successors  and assigns of each Grantor and shall inure to the benefit
of the  Collateral  Agent  and the  Secured  Parties  and their  successors  and
assigns;  provided  that no Grantor may assign,  transfer or delegate any of its
rights or obligations  under this Agreement without the prior written consent of
the Collateral Agent.

                  8.6 Set-Off.  Each Grantor hereby  irrevocably  authorizes the
Collateral  Agent and each Secured Party at any time and from time to time while
a Notice of  Enforcement  is in effect,  without  notice to such  Grantor or any
other  Grantor,  any such notice  being  expressly  waived by each  Grantor,  to
set-off and appropriate and apply any and all deposits (general or special, time
or  demand,  provisional  or final),  in any  currency,  and any other  credits,
indebtedness  or  claims,  in any  currency,  in each  case  whether  direct  or
indirect,  absolute or  contingent,  matured or  unmatured,  at any time held or
owing by the Collateral  Agent or such Secured Party to or for the credit or the
account of such Grantor,  or any part thereof in such amounts as the  Collateral
Agent or such Secured Party may elect, against and on account of the obligations
and  liabilities of such Grantor to the  Collateral  Agent or such Secured Party
hereunder and claims of every nature and description of the Collateral  Agent or
such Secured  Party  against such  Grantor,  in any  currency,  whether  arising
hereunder,  the Security Documents, any Secured Instruments or otherwise, as the
Collateral Agent or such Secured Party may elect,  whether or not the Collateral
Agent or any Secured  Party has made any demand for payment  and  although  such
obligations,  liabilities  and  claims  may  be  contingent  or  unmatured.  The
Collateral  Agent and each Secured  Party shall notify such Grantor  promptly of
any  such  set-off  and the  application  made by the  Collateral  Agent or such
Secured  Party of the proceeds  thereof,  provided that the failure to give such
notice shall not affect the validity of such set-off and application. The rights
of the  Collateral  Agent and each  Secured  Party  under  this  Section  are in
addition to other  rights and remedies  (including,  without  limitation,  other
rights of set-off) which the Collateral Agent or such Secured Party may have.

                  8.7  Counterparts.  This  Agreement  may be executed by one or
more of the parties to this  Agreement  on any number of  separate  counterparts
(including by telecopy),  and all of said  counterparts  taken together shall be
deemed to constitute one and the same instrument.

                  8.8  Severability.  Any provision of this  Agreement  which is
prohibited or unenforceable in any jurisdiction  shall, as to such jurisdiction,
be ineffective to the extent of such  prohibition  or  unenforceability  without
invalidating  the  remaining  provisions  hereof,  and any such  prohibition  or
unenforceability   in  any   jurisdiction   shall  not   invalidate   or  render
unenforceable such provision in any other jurisdiction.

                  8.9  Section  Headings.  The  Section  headings  used  in this
Agreement  are for  convenience  of  reference  only and are not to  affect  the
construction hereof or be taken into consideration in the interpretation hereof.

                  8.10  Integration.  This  Agreement  and  the  other  Security
Documents represent the agreement of the Grantors,  the Collateral Agent and the
Secured Parties with respect to the

subject  matter  hereof and thereof,  and there are no  promises,  undertakings,
representations  or  warranties  by the  Collateral  Agent or any Secured  Party
relative  to  subject  matter  hereof and  thereof  not  expressly  set forth or

                  8.11  GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED

OF THE STATE OF NEW YORK.

                  8.12  Submission To Jurisdiction; Waivers. Each Grantor hereby
irrevocably and unconditionally:

                  (a) submits for itself and its property in any legal action or
         proceeding  relating to this Agreement and the other Security Documents
         to which it is a  party,  or for  recognition  and  enforcement  of any
         judgment in respect thereof, to the non-exclusive  general jurisdiction
         of the Courts of the State of New York, the courts of the United States
         of America for the Southern  District of New York, and appellate courts
         from any thereof;

                  (b) to the extent  permitted by applicable law,  consents that
         any such action or proceeding  may be brought in such courts and waives
         any  objection  that it may now or  hereafter  have to the venue of any
         such  action or  proceeding  in any such  court or that such  action or
         proceeding was brought in an inconvenient court and agrees not to plead
         or claim the same;

                  (c) agrees  that  service  of  process  in any such  action or
         proceeding  may be effected by mailing a copy thereof by  registered or
         certified  mail (or any  substantially  similar form of mail),  postage
         prepaid,  to such Grantor at its address  referred to in Section 8.2 or
         at such other  address of which the  Collateral  Agent  shall have been
         notified pursuant thereto;

                  (d)  agrees  that  nothing  herein  shall  affect the right to
         effect service of process in any other manner permitted by law or shall
         limit the right to sue in any other jurisdiction; and

                  (e) waives,  to the maximum  extent not prohibited by law, any
         right it may have to claim or recover in any legal action or proceeding
         referred  to in  this  Section  any  special,  exemplary,  punitive  or
         consequential damages.

                  8.13 Acknowledgements. Each Grantor hereby acknowledges that:

                  (a)  it has  been  advised  by  counsel  in  the  negotiation,
         execution  and  delivery  of  this  Agreement  and the  other  Security
         Documents to which it is a party;

                  (b) neither the Collateral Agent nor any Secured Party has any
         fiduciary relationship with or duty to any Grantor arising out of or in
         connection with this



<PAGE>


                                                                              32



         Agreement or any of the other Security Documents,  and the relationship
         between the Grantors,  on the one hand,  and the  Collateral  Agent and
         Secured Parties, on the other hand, in connection herewith or therewith
         is solely that of debtor and creditor; and

                  (c) no joint venture is created  hereby,  by this Agreement or
         by the other  Security  Documents or otherwise  exists by virtue of the
         transactions contemplated hereby among the Secured Parties or among the
         Grantors and the Secured Parties.

                  8.14 Additional Grantors. Each Subsidiary of the Borrower that
is required to become a party to this Agreement pursuant to a Secured Instrument
shall become a Grantor for all purposes of this  Agreement  upon  execution  and
delivery by such  Subsidiary of an  Assumption  Agreement in the form of Annex 1
hereto.

                  8.15  Releases.  (a) At such  time as the  Loans and the other
Obligations  (including  Obligations in respect of Permitted  Letters of Credit,
but excluding other unaccrued  contingent  obligations)  shall have been paid in
full and all Secured Obligation Commitments have been terminated, the Collateral
shall  automatically  and immediately be released from the Liens created hereby,
and this Agreement and all  obligations  (other than those  expressly  stated to
survive such  termination)  of the Collateral  Agent and each Grantor  hereunder
shall  automatically  and  immediately  terminate,  all without  delivery of any
instrument  or  performance  of any  act by any  party,  and all  rights  to the
Collateral shall revert to the Grantors.  Upon such termination,  the Collateral
Agent will promptly,  at the Borrower's written request and expense, (i) execute
and deliver to the Borrower such documents and  instruments  and take such other
actions as the  Borrower  shall  reasonably  request to  evidence  or effect the
release of such  Collateral and (ii) in the case of a release of all Collateral,
deliver or cause to be delivered to the Borrower all  Possessory  Collateral and
all other property of the Borrower (including,  without limitation,  all amounts
deposited or held in the Collateral  Account,  and all Cash Equivalents or other
investments, together with all interest, dividends or profits thereon) then held
by the Collateral Agent or any agent thereof.

                  (b) If any of the  Collateral  shall be sold,  transferred  or
otherwise  disposed of by any Grantor in a transaction  permitted by the Secured
Instruments,  then the Collateral Agent, at the request and sole expense of such
Grantor,  shall  execute  and  deliver to such  Grantor  all  releases  or other
documents reasonably necessary or desirable for the release of the Liens created
hereby on such Collateral. At the request and sole expense of the Borrower or if
it is no longer required to be a Guarantor pursuant to the Secured  Instruments,
a Guarantor shall be released from its  obligations  hereunder in the event that
all the Capital Stock of such Guarantor shall be sold,  transferred or otherwise
disposed of in a transaction permitted by the Secured Instruments; provided that
the Borrower shall have delivered to the Collateral Agent, at least ten Business
Days prior to the date of the proposed  release,  a written  request for release
identifying the relevant Guarantor and, if applicable,  the terms of the sale or
other  disposition  in  reasonable  detail,  including the price thereof and any
expenses in connection therewith,  together with a certification by the Borrower
stating that such transaction is in compliance with the Secured Instruments.

                  sary or appropriate as a basis for the opinions
                  set forth below.

                  Unless otherwise  indicated,  (i) "Loan Docu ments" shall mean
the  documents  referred to in clauses (a)  through  (d) above;  (ii)  "Security
Documents"  shall mean the agreements  referred to in clauses (c) and (d) above;
and (iii)  references  to the term  "UCC"  shall  mean (A) with  respect  to the
validity of the security  inter ests granted under the Guarantee and  Collateral
Agree ment, the Uniform  Commercial  Code as in effect on the date hereof in the
State of New York;  (B) with respect the perfection and the effect of perfection
or non-per  fection of the security  interests in the UCC Filing  Collateral (as
such term is hereinafter  defined),  the Uniform Commercial Code as in effect on
the date hereof in the  Commonwealth  of  Virginia;  and (C) with respect to the
perfection  and the  effect of  perfection  or non-per  fection of the  security
interests  in the  Pledged  Stock (as such  term is  hereinafter  defined),  the
Uniform  Com  mercial  Code as in effect on the date  hereof in the State of New
York.

                  We express no opinion as to the laws of any other jurisdiction
other than (i) the laws of the State of New York;  (ii) solely  with  respect to
the opinions set forth in paragraphs 1 through 4 hereof, the General Corporation
Law and the Limited Liability Company Act of the State of Delaware; (iii) solely
with respect to the



<PAGE>


The Lenders set forth

security interest opinions set forth in paragraphs 9 through 12 hereof, the UCC;
and (iv) the  federal  laws of the  United  States  to the  extent  specifically
referred  to herein.  We are not  admitted  to the bar of the  Common  wealth of
Virginia and our opinion as to the UCC relating to the Uniform  Commercial  Code
in the  Commonwealth  of Virginia is based on our  familiarity  with the Uniform
Commercial Code as in effect on the date hereof in the Commonwealth of Virginia.

                  We call to your  attention  that  provisions  of the  Security
Documents  purport to grant to, and create in favor of, the Collateral  Agent, a
direct and  indirect  security  interest in  authorizations  and  licenses  (the
"Licenses")  issued by the  Federal  Communications  Commis sion (the "FCC") and
remedial rights, powers and remedies with respect thereto,  which (including any
rights  or  interests  therein)  may  be  subject  to  Communications  Laws  (as
hereinafter defined) and Communications  Approvals (as hereinafter  defined). We
express  no opinion as to the  effect on the  opinions  expressed  herein of the
applica tions or effect of Communications Laws or Communications  Approvals. Our
opinion with respect to the security  interest of the  Collateral  Agent for the
benefit of the Lenders in the  Licenses and in the equity  interests  (including
membership  interests) of each of the Companies  holding the Licenses is limited
to the UCC, and Communi cations Laws (including  requirements of  Communications
Approvals) may limit or affect, among other things, the validity of the security
interests,  the exercise of remedies with respect to the Licenses or such equity
interests  (including  membership  interests) and the abil ity of the Collateral
Agent to realize  the  benefits of any  security  interests,  rights,  powers or
remedies in respect thereof.  As used herein, (i) the term "Communi cations Law"
shall mean laws,  rules and regulations  pertaining to the Licenses,  including,
without limita tion, the Communications Act of 1934, as amended,  includ ing the
Telecommunications  Act of 1996,  and, where appli cable,  the published  rules,
regulations, decisions and orders of the FCC; and (ii) the term "Communications

Approval"  shall mean any consent,  approval,  license or  authorization  of, or
filing, registration or application with, the FCC or any other federal, state or
other  regu  latory  authority  pursuant  to  Communications  Laws  required  to
transfer,  whether directly or indirectly, the Licenses or any right or interest
therein.

                  Our opinions set forth below are also subject to the following
qualifications:

                           i.  enforcement  of the Loan Documents may be limited
         by  applicable  bankruptcy,  insolvency,  reorganization,   moratorium,
         fraudulent  transfer or other similar laws affecting  creditors' rights
         generally  and by general  principles of equity (re gardless of whether
         enforcement is sought in equity or at law);

                           ii.  certain of the  remedial  provisions,  including
         waivers,   with  respect  to  the  exercise  of  remedies  against  the
         collateral  contained in the Security Documents may be unenforceable in
         whole or in part, but the inclusion of such  provisions does not affect
         the validity of each such  Security  Docu ment,  taken as a whole,  and
         each  such  Security  Docu  ment,  taken  as  a  whole,  together  with
         applicable  law,  contains   adequate   provisions  for  the  practical
         realization of the benefits of the security provided thereby;

                           iii. we have assumed that each of the Loan  Documents
         constitutes  the legal,  valid and binding  obligation of each party to
         such Loan Documents (other than the Companies) enforceable against such
         party (other than the Companies) in accordance with its terms;

                           iv. we  express  no  opinion  as to the effect on the
         opinions  expressed herein of (A) the compli ance or  non-compliance of
         the  Administrative  Agent,  the Lenders or any party  (other than each
         Company)

         to the  Loan  Documents  with  any  state,  federal  or  other  laws or
         regulations  applicable  to any of them, or (B) the legal or regulatory
         status or the nature of the business of the  Administrative  Agent, the
         Lenders or any party to the Loan Documents (other than each Company);

                           v. enforcement of the Security Documents with respect
         to  collateral  consisting  of  the  inter  est  of  the  Companies  in
         instruments, leases, con tracts or other agreements (collectively, "Con
         tracts") between the Companies and the other parties to such Contracts,
         may be subject to the terms of such Contracts, the rights of such other
         parties  to such  Contracts  and any claims or  defenses  of such other
         parties against the Companies arising under or outside such Contracts;

                           vi. we express no opinion as to the enforceability of
         any rights to contribution or indemnification  provided for in any Loan
         Document  which are violative of the public policy  underlying any law,
         rule or regulation (including, without limitation, any federal or state
         securities law, rule or regulation);

                           vii. we express no opinion as to any provision of any
         Loan  Document  to the  extent it  authorizes  or  permits  any  Person
         (including any purchaser of a participation  interest),  other than the
         party to any Loan Document to whom an obligation is owed, to set-off or
         apply  any  deposit,  property  or  indebtedness  in  respect  of  such
         obligation;

                           viii.  we have assumed that the  execution,  delivery
         and  performance by the Companies of the Loan Documents do not and will
         not conflict  with,  contravene,  violate or constitute a default under
         (a) any lease,  indenture,  instrument or other agree ment to which any
         such Person is subject (other than Applicable  Contracts as to which we
         express our

         opinion in  paragraph 5 herein),  (b) any rule,  law or  regulation  to
         which any such  Person is subject  (other  than  Applicable  Laws as to
         which we express our opinion in  paragraph 6 herein);  (c) any judicial
         or administrative order or decree of any governmen tal authority (other
         than Applicable  Orders as to which we express our opinion in paragraph
         8 herein);  or (d) any consent,  approval,  license,  authorization  or
         validation  of,  or  filing,  recording  or  regis  tration  with,  any
         governmental  authority (other than Governmental  Approvals as to which
         we express our opinion in paragraph 7 herein);

                           ix. we have assumed that no authoriza  tion,  consent
         or other approval of, notice to or filing with any court,  governmental
         authority or regulatory body (other than  Governmental  Approvals as to
         which we express  our  opinion in  paragraph  7 herein) is  required to
         authorize or is required in connection with the execution,  delivery or
         perfor mance by the Companies of the Loan Documents; and

                           x.       we express no opinion as to the
         applicability or effect of any fraudulent transfer
         or similar law on the Loan Documents or the transac
         tions contemplated thereby.

                  We  understand  further  that  you  are  separately  receiving
opinions  from other  counsel  (the "Other  Counsel  Opinions")  with respect to
certain aspects of the forego ing, and we are advised that such opinions contain
quali  fications.  Our  opinions  herein  stated  are  based on the  assumptions
specified  above,  and we do not  express  any  opinion  as to the effect on the
opinions herein stated of the qualifications contained in the Other Counsel Opin
ions.

                  Based  upon the  foregoing  and  subject  to the  limitations,
qualifications,  exceptions  and  assumptions  set forth  herein,  we are of the
opinion that:

                  4. Neither the  execution and delivery by any of the Companies
of the Loan Documents to which it is a party nor the performance by such Company

York  and of the  United  States  of  America  (including,  without  limitation,
Regulations  U and X of the Board of  Governors of the Federal  Reserve  System)
which,  in our experience,  are normally  applicable to transactions of the type
contemplated by the Loan Documents and which, in any event, do not include Commu
nications Laws.

                  7. No Governmental  Approval (as hereinafter  defined),  which
has not been  obtained  and is not in full  force and  effect,  is  required  to
authorize  or  is  required  in  connection  with  the  execution,  delivery  or

intellectual  property rights.  "Govern mental Approval" shall mean any consent,
approval,  li cense,  authorization  or validation of, or filing,  record ing or

shall exclude all Communications Approvals.

                  8. Neither the  execution,  delivery or perfor mance by any of
the Companies of its obligations under the Loan Documents to which it is a party
nor  compliance  by such  Person  with the terms  thereof  will  contravene  any
Applicable Order against such Company. The term "Appli cable Orders" means those

                  9. The  provisions of the Guarantee and Col lateral  Agreement
are effective to create, in favor of the Collateral Agent for the benefit of the
Lenders  to secure  the  Secured  Obligations  (as such term is  defined  in the
Guarantee and Collateral Agreement), a valid security interest in the Borrower's
rights in the  certif  icates  identified  on  Schedule 2 to the  Guarantee  and
Collateral Agreement (the "Pledged Stock").

                  10. Upon  delivery  of the  Pledged  Stock in the State of New
York to the  Collateral  Agent for the  benefit  of the  Lenders,  the  security
interest  of the  Collateral  Agent  for  the  benefit  of the  Lenders  will be
perfected.  No interest of any other  creditor of the Borrower is equal or prior
to the security  interest of the Collateral Agent for the benefit of the Lenders
in the Pledged Stock.

                  Our  opinions  in  paragraphs  9 and  10  are  subject  to the
following qualifications:

                           i. we have assumed that the Borrower owns the Pledged
         Stock,  and we  express  no  opinion  as to the nature or extent of the
         Borrower's rights in, or title to, any of the Pledged Stock;

                           ii. our opinions  with respect to the interest of the
         Collateral  Agent for the benefit of the Lenders are limited to Article
         8 and Article 9 of the UCC,  and such  opinions do not address (i) laws
         of  jurisdictions  other  than New  York,  and of New York  except  for
         Article  8 and  Article  9 of the UCC,  (ii)  collateral  of a type not
         subject  to Arti  cle 8 and  Article  9 of the  UCC,  and  (iii)  under
         Sections 9-103 and 8-110,  what law governs perfec tion of the security
         interests granted in the col lateral covered by this opinion;

                           iii.  we call to your  attention  that under the UCC,
         events occurring subsequent to the date



<PAGE>


The Lenders set forth

Page 10

         hereof may affect any security  interest  subject to the UCC including,
         but not limited to,  factors of the type  identified  in Section  9-306
         with  respect to  proceeds;  Section  9-402 with  respect to changes in
         name,  structure and corporate identity;  Section 9-103 with respect to
         changes in the location of the collateral and the location of a debtor;
         Section 9-316 with respect to subordination  agreements;  Section 9-403
         with respect to continuation state ments; and Sections 9-307, 9-308 and
         9-309 with  respect to  subsequent  purchasers  of the  collateral.  In
         addition,  actions  taken  by  a  secured  party  (e.g.,  releasing  or
         assigning  the  security  interest,   deliv  ering  possession  of  the
         collateral to a debtor or another person and voluntarily  subordinating
         a security  interest) may affect any security  interest  subject to the
         UCC;

                           iv.  we  express  no  opinion  with  respect  to  the
         priority  of the  security  interest  of the Collat  eral Agent for the
         benefit of the Lenders in the Pledged  Stock against a lien creditor to
         the  extent  that  Section  9-301(4)  of the UCC  limits  the  priority
         afforded future advances;

                           v. we have  assumed  that the  Collateral  Agent  has
         acquired its interest for the benefit of the Lenders for value and that
         neither the Collat eral Agent nor the Lenders has notice on or prior to
         the date  hereof or the date of  delivery  of the  Pledged  Stock of an
         adverse claim with respect to the Pledged Stock; and

                           vi. we call to your attention that Section 324 of the
         Delaware  General  Corporation Law provides that the shares of stock of
         any person in a Delaware  corporation  may be  attached  and sold for a
         debt or in response to other demands and, therefore, it is possible for
         there to be an attachment  of  securities  under Section 324 that takes
         precedence over the pledge of securities if the securities are not

          registered  on the books of the  issuer in the name of the  Collateral
          Agent for the benefit of the Lenders.

                  11. The provisions of the Guarantee and Col lateral  Agreement
are effective to create, in favor of the Collateral Agent for the benefit of the
Lenders to secure each respective Company's Obligations (as such term is defined
in the Guarantee and Collateral  Agree ment), a valid security  interest in each
Company's  rights in that portion of the collateral  described  therein which is
subject to Article 9 of the UCC (the "UCC Collateral").

                  12. The  Financing  Statements  are in  appropri  ate form for
filing in each of the Filing  Offices.  With  respect to that portion of the UCC
Collateral as to which the filing of a financing  statement in the  Commonwealth
of Virginia is a permissible method of perfection under the UCC (the "UCC Filing
Collateral"),  the security  interest of the Collateral Agent for the benefit of
the Lenders in that portion of the UCC Filing  Collateral  which is described in
the  Financing  Statements  will  be  perfected  upon  filing  of the  Financing
Statements in the respective Filing Offices.

                  Our  opinions  in  Paragraphs  11 and 12 are  sub  ject to the
following qualifications:

                           i. we have assumed that each  Company  owns,  or with
         respect to after-acquired  property will own, the collateral pledged by
         such  Company,  and we express no opinion as to the nature or extent of
         any Company's rights in, or title to, any of the collateral and we note
         that with respect to any after-acquired property, the security interest
         will not attach  until the  Company  pledging  such  property  acquires
         ownership thereof;

                           ii. our opinions  with respect to the interest of the
         Collateral  Agent for the benefit of the Lenders are limited to Article
         9 of the UCC, and



<PAGE>


The Lenders set forth

         therefore such opinions do not address (A) laws of jurisdictions  other
         than the Commonwealth of Vir ginia, and of the Commonwealth of Virginia
         except for Article 9 of the UCC, (B)  collateral  of a type not subject
         to Article 9 of the UCC, and (C) under  Section  9-103 of the UCC, what
         law governs  perfec tion of the security  interests  granted in the col
         lateral covered by this opinion;

                           iii.  we call to your  attention  that under the UCC,
         events occurring  subsequent to the date hereof may affect any security
         interest  subject to the UCC including,  but not limited to, factors of
         the type identified in Section 9-306 with respect to proceeds;  Section
         9-402 with respect to changes in name, structure and corporate identity
         of the debt or;  Section  9-103 with respect to changes in the location
         of the  collateral  and the location of the debtor;  Section 9-316 with
         respect to  subordination  agreements;  Section  9-403 with  respect to
         continua  tion  statements;  and Sections  9-307,  9-308 and 9-309 with
         respect to  subsequent  purchasers  of the col  lateral.  In  addition,
         actions  taken by a secured  party (e.g.,  releasing  or assigning  the
         security  interest,  delivering  possession  of the  collateral  to the
         debtor or another  person  and  voluntarily  subor  dinating a security
         interest) may affect any securi ty interest subject to the UCC;

                           iv. we have  assumed  that the only place of business
         of the Companies in the  Commonwealth of Virginia is located in Vienna,
         Fairfax County;

                           v.  except to the extent set forth in our  opinion in
         paragraph 10, we express no opinion with respect to the priority of the
         security  interest  of the  Collateral  Agent  for the  benefit  of the
         Lenders in any of the Collateral;

                           vi.  in the  case of  chattel  paper,  ac  counts  or
         general intangibles, we call to your



<PAGE>


The Lenders set forth

Page 13

         attention  that the security  interest of the Collat eral Agent for the
         benefit of the Lenders may be subject to the rights of account debtors,
         claims and  defenses  of account  debtors  and the terms of agree ments
         with account debtors;

                           vii.  we express no opinion  regarding  the  security
         interest of the Collateral  Agent for the benefit of the Lenders in any
         copyrights,  patents,  trademarks,  service marks or other intellectual
         property,  the proceeds  thereof or any rights (in cluding  accounts or
         general intangibles) with re spect to the lease, license or use thereof
         except  to the  extent  Article 9 of the UCC may be  applicable  to the
         foregoing and except to the extent of our opin ion in paragraph 13;

                           viii.  we call to your  attention  that,  under  U.S.
         trademark law, it is generally held that transfers of trademark  rights
         are invalid unless  accompanied  by the related  goodwill and the trade
         marks  are used on  substantially  the same  goods as those  previously
         represented  by the  trademarks  and we express no  opinions  as to the
         assets or goodwill  that would have to accompany  the  Trademarks to en
         sure  continuing  validity  of  such  Trademarks  in  the  event  of  a
         foreclosure and the ultimate disposition of such trademarks as a result
         of a default.

                           ix.  in the case of  goods,  we  express  no  opinion
         regarding the security interest of the Collateral Agent for the benefit
         of the  Lenders in any goods which are (A) an  accession  to, or commin
         gled or  processed  with other  goods to the extent  that the  security
         interest  of the  Collateral  Agent for the  benefit of the  Lenders is
         limited  by Section  9-314 or 9-315 of the UCC or (B)  subject to a cer
         tificate of title or a document of title;

                           x. except to the extent of the opinions  expressed in
         paragraph  13 of this  opinion,  we ex press no opinion  regarding  the
         security  interest  of the  Collateral  Agent  for the  benefit  of the
         Lenders in any items  which are  subject to a statute,  regula  tion or
         treaty of the United States of America which provides for a national or
         international registra tion or a national or international  certificate
         of title for the  perfection  of a security  interest  therein or which
         specifies a place of filing differ ent from the place  specified in the
         UCC for filing to perfect such security interest;

                           xi. we  express  no opinion  regarding  the  security
         interest of the Collateral  Agent for the benefit of the Lenders in any
         of the  collateral  con  sisting of claims  against any  government  or
         govern mental agency (including without limitation the United States of
         America or any state  thereof or any agency or department of the United
         States of America or any state thereof);

                           xii. in the case of any  instrument,  chat tel paper,
         account  or  general  intangible  which  is  itself  secured  by  other
         property,  we express no opinion with respect to the Collateral Agent's
         rights  for  the  benefit  of the  Lenders  in and to  such  underlying
         property;

                           xiii.  we  express  no  opinion  with  respect to the
         security  interest in any of the  collateral  consisting of goods which
         are or are to become fixtures, equipment used in farming operations, or
         farm  products,  or accounts  or general  intangibles  arising  from or
         relating  to the sale of farm prod ucts by a  farmer,  consumer  goods,
         crops growing or to be grown,  timber to be cut or minerals or the like
         (including oil and gas) or accounts  subject to subsection 5 of Section
         9-103 of the UCC;

                           xiv. we call to your  attention  that  changes in the
         nature of the  collateral  (including  but not  limited  to  collateral
         consisting of the

         membership  interests referred to in the preceding sentence) may affect
         the security  interest of the  Collateral  Agent for the benefit of the
         Lenders  and we express no opinion as to the  security  interest of the
         Collateral  Agent for the  benefit of the Lenders in the event that any
         such  changes  take place (in  cluding any such  changes  that make the
         assumptions in the preceding sentence untrue);

                           xv. we call to your  attention  that the right of the
         Collateral Agent for the benefit of the Lenders to become a member of a
         limited  liability  company  whose  interests  have been pledged may be
         limited by applicable law and by the terms of the documents pursuant to
         which  it has been  formed,  as  amended  from  time to time (we  note,
         however,  that the LLC Documents,  as in effect on the date hereof,  do
         not  contain any such  limitation)  and that the only remedy may be the
         right to  receive  distribu  tions to which any  Company  is  otherwise
         entitled pursuant to such documents; and

                           xvi.  we call to your  attention  that in the case of
         licenses or permits issued by governmen tal authorities, the applicable
         Company  may not  have  sufficient  rights  therein  for  the  security
         interest  of the  Collateral  Agent for the  benefit of the Lend ers to
         attach and even if such Company has suffi cient rights for the security
         interest to attach, exercise of remedies may be limited by the terms of
         the  license  or permit or  require  the  consent  of the  governmental
         authority  issuing such license or per mit. We have assumed that to the
         extent the terms of  licenses  or permits  (or any laws or  regulations
         applicable thereto) prohibit or condition the trans fer of any licenses
         or permits,  consent to the transfer under the Guarantee and Collateral
         Agree ment has been obtained.

                  13.  To the  extent  that the  federal  trademark  laws of the
United States are  applicable,  the  provisions of the Guarantee and  Collateral
Agreement,  together  with  the  recordation  of the  Guarantee  and  Collateral
Agreement in the United States  Patent and Trademark  office within three months
of the date hereof, will be effective to create in favor of the Collateral Agent
for the benefit of the Lenders, a valid security interest in the U.S. registered
trademarks  and U.S.  trademark  applications  set  forth on  Schedule  6 to the
Guarantee  and  Collateral  Agreement  (the  "Trademarks"),  which is  effective
against subsequent purchasers of such Trademarks.

                  The opinions expressed in this paragraph 13 are subject to the
following qualifications:

                           i. we have assumed that the  representa  tions in the
         Guarantee  and  Collateral  Agreement,  including  the  information  on
         Schedule 6 to the Guar antee and Collateral Agreement, will be accurate
         and  complete  as of the  date  of the  filing  of the  Guaran  tee and
         Collateral Agreement;

                           ii. we have  assumed  the  Trademarks  exist and that
         Borrower  has  sufficient  rights in the  Trademarks  for the  security
         interest of the Collat eral Agent to attach,  and we express no opinion
         as to the  nature or extent of the  Borrower's  rights in, or title to,
         any of the Trademarks;

                           iii. we have  assumed that there has been no transfer
         or other event  affecting the Borrower's  right,  title and interest in
         the Trademarks  which has occurred  either within three months prior to
         the date hereof or earlier  than three  months prior to the date hereof
         but which is not recorded prior to the date hereof;

                           iv.  we  express  no  opinion  with  respect  to  the
         security  interest of the Collateral  Agent in any trademarks which are
         either acquired by any

         Company subsequent to the date hereof or otherwise
         not identified in Schedule 6 to the Guarantee and
         Collateral Agreement;

                           v. we call your  attention  to the fact  that,  under
         Section 10 of the United  States Trade mark Act (the "Lanham  Act") (15
         U.S.C.  1060), no application to register a mark based on intent to use
         shall be assignable prior to the filing of a verified  statement of use
         with the United States Patent and Trademark  Office pursuant to Section
         1(d) of the Lanham Act,  except to a successor  to the  business of the
         applicant,  or portion  thereof,  to which the mark  pertains,  if that
         business is ongoing and existing;

                           vi.  we call  your  attention  to the  fact  that the
         exercise  of  remedies  with  respect  to the  Trademarks  may  require
         additional filings with the United States Patent and Trademark Office;

                           vii.   we express no opinion as to the
         priority of the security interest of the Collateral
         Agent in the Trademarks;

                           viii.  we have assumed  that there are no  agreements
         between the Borrower and any account debtor prohibiting, restricting or
         conditioning  the  Borrower's  right to assign or grant a  security  in
         terest in any portion of the Trademarks;

                           ix.   we express no opinion as to the
         validity or enforceability of any Trademark; and

                           x.  we  call  to  your  attention  that,  under  U.S.
         trademark law, it is generally held that trans fers of trademark rights
         are  invalid  unless  accompa  nied  by the  related  goodwill  and the
         trademarks  are used on  substantially  the same  goods as those  previ
         ously  represented  by the  trademarks and we express no opinions as to
         the assets or goodwill that would

         have to accompany the Trademarks to ensure continu ing validity of such
         Trademarks in the event of a foreclosure  and the ultimate  disposition
         of such trademarks as a result of a default.

                  14. No  registration  of any  Company  is  required  under the
Investment Company Act of 1940.

                  15. No Company is a "holding  company"  within the  meaning of
the Public Utility Holding Company Act of 1935, as amended.

                  This opinion is being furnished only to you in connection with
the Credit Agreement and the transactions contemplated thereby and is solely for
your benefit and is not to be used, circulated, quoted, relied upon or otherwise

                           --------------
Ladies and Gentlemen:

                  We have acted as  special  counsel to (i)  Teligent,  Inc.,  a

execution  and delivery of the Credit  Agreement,  dated as of July 2, 1998 (the

"LicenseCo"),   Teligent   Telecommunications,   Inc.,  a  Delaware  corporation

dated  July 2, 1998 (the  "Guarantee  and  Collateral  Agreement"),  made by the

                  This opinion is being furnished  pursuant to Section 4.1(m)(i)
of the Credit Agreement. Capitalized terms used and not otherwise defined herein
shall have the respective meanings set forth in the Credit Agreement.

                  In connection with this opinion, we have examined originals or
copies, certified or otherwise identified to our satisfaction, of (i) the Credit
Agreement,  dated July 2,  1998;  (ii) an  executed  copy of the  Guarantee  and
Collateral  Agreement;  and (iii) the  authorizations and licenses issued by the
Federal  Communication  Commission ("FCC") to the Companies listed on Schedule I
hereto (the "Licenses"). We have also examined originals or copies, certified or
otherwise  identified to our satisfaction,  of such records of the Companies and
such agreements,  certificates of public officials,  certificates of officers or
other  representatives  of the Companies and such other documents,  certificates
and  records  as we have  deemed  necessary  or  appropriate  as a basis for the
opinions set forth herein.

                  In addition, we have examined files available to the public at
the FCC and FCC databases maintained by Interactive  Systems,  Inc. (which has a
contract with the FCC to provide public access to the FCC's databases)  relating
to the Licenses as of June 29, 1998. We have also examined and are familiar with
originals or copies,  certified or otherwise identified to our satisfaction,  of
such  records  of  the  Companies,  such  agreements,   the  attached  Officer's
Certificate of the Borrower ("Officer's Certificate"), and such other documents,
certificates  and records as we have deemed  necessary or appropriate as a basis
for the opinions set forth herein.

                  For  purposes  of our  opinion,  we  have  assumed  the  legal
capacity  of  all  natural  persons,  the  genuineness  of all  signatures,  the
authenticity  of all documents  submitted to us as originals,  the conformity to
original documents of all documents  submitted to us as certified or photostatic
copies and the authenticity of the originals of such latter documents. In making
our examination of documents  executed by par ties other than the Companies,  we
have assumed that such parties had the power,  corporate or other, to enter into
and  perform  all   obligations   thereunder  and  have  also  assumed  the  due
authorization  by all requisite  action,  corporate or other, and execu tion and
delivery by such parties of such  documents and the validity and binding  effect
thereof. In addition,  we have assumed that the FCC's public files and databases
are correct,  complete and  accurate.  As to any facts  material to this opinion
that we did not  independently  establish  or verify,  we have  relied,  without
indepen dent verification,  upon oral or written statements and  representations
of officers and other representatives of the Companies and others.

                  We have not conducted an on-site  investigation  of any of the
Companies' facilities associated with the Licenses (collectively the "Systems"),
nor have we examined the operations of the Systems.  Thus, we express no opinion
as to the operation of the Systems or their  compliance  with applicable laws or
the effect of such operation or lack thereof or  non-compliance,  if any, on the
validity of the Licenses.

                  As used herein,  (i) the term  "Communications  Act" means the
Communications Act of 1934, as amended,  including the Telecommunications Act of
1996, and, where  applicable,  the published rules,  regulations,  decisions and
orders of the FCC in each case as in  effect  on the date  hereof;  and (ii) the
term  "Governmental   Approval"  means  any  consent,   approval,   license,  or
authorization of, or filing with, the FCC pursuant to the Communications Act.

                  Members of this firm are  admitted to the Bar of the  District
of Columbia and this opinion is limited to the Communications Act. We express no
opinion as to any laws of the United States other than the Communications Act or
of any  foreign  country or of any  federal,  state or local  authority,  or any
rules, regula tions or decisions of any other federal, state, or local agency or
administrative  body other than the FCC or agency or ministry or regulatory body
of any foreign country.

                  Based  upon  and  subject  to  the   foregoing,   and  to  the
limitations, qualifications, exceptions, facts and assumptions set forth herein,
we are of the opin ion that:

                  1. The  Companies  are duly  authorized by the FCC to hold the
Authorizations  and  Licenses  identified  in Schedule I. Based on the  attached
Officer's  Certificate as to matters of fact, the Licenses are in full force and
effect  and have not been  revoked,  suspended,  cancelled  or  modified  in any
adverse way and,  except as set forth on  Schedules  I and I-A  hereto,  are not
subject to any conditions or require ments that are not generally imposed by the
FCC upon the holders of such licenses.

                  2. Based solely on (i) inquiry to the appropriate  officers of
the Companies without  independent  verification and (ii) our examination of the
publicly  available files at the FCC and FCC databases as described  above,  and
except as set forth in Schedule II hereto,  (A) the Companies have paid all fees
and have made all reports  and  filings,  including  tariffs  where  applicable,
required  by the FCC for the  conduct of their  businesses  in the manner as set
forth in the  Teligent,  Inc.  Confidential  Information  Memorandum  (May 1998)
("Information  Memo"),  (B) no further FCC  authorizations  are  required by the
Companies to conduct their  business as set forth in the  Information  Memo, and
(C) there are no complaints, investigations,  protests, proceedings or petitions
outstanding or to our knowledge threatened at or by the FCC, formal or informal,
against  the  Companies  or the  Licenses  or any  adverse  judgments,  decrees,
injunctions,  or published  orders of any court or the FCC naming the  Companies
that  are  likely  to  result  in  the  revocation,   suspension,   termination,
non-renewal  or material  adverse  modification  of the  Licenses or prevent the
Companies from conducting their current business as set forth in the Information
Memo.

                  3. Based on the attached  Officer's  Certificate as to matters
of fact,  neither  the  execution  or  delivery  of, or the  performance  by the
Companies  of  their  obligations  under  the  Transaction  Documents,  nor  the
consummation by the Companies of the  transactions  contemplated  therein,  will
violate the Communi cations Act.

                  4. Based on the attached  Officer's  Certificate as to matters
of fact, no  Governmental  Approvals are necessary for the execution or delivery
of,  or  the  performance  by the  Companies  of  their  obligations  under  the
Transaction  Documents or  consummation  by the  Companies  of the  transactions
contemplated  therein in accordance with the terms thereof and such consummation
will not cause any cancellation, termination, revocation, forfeiture or material
impairment of any of the Licenses or prevent the Companies from conducting their
current business as set forth in the Information Memo.

                  5. Based on the attached  Officer's  Certificate as to matters
of fact, and subject to the assumptions and  qualifications set forth below, the
Borrower is in compliance with the statutory foreign ownership limitations of 47
U.S.C. ss.

Assumptions and Qualifications

                  With  respect to the opinion  set forth in  paragraph 5 above,
Section  310(b) of the  Communications  Act provides in  pertinent  part that no
common  carrier  radio  station  license  shall be granted to or held by (1) any
corporation of which more than one-fifth of the capital stock is owned of record
or voted by  aliens  or their  representatives  or by a  foreign  government  or
representative  thereof  or by any  corporation  organized  under  the laws of a
foreign country or (2) to any corporation  directly or indirectly  controlled by
another  corporation of which more than one-fourth of the capital stock is owned
of  record  or  voted  by  aliens  or their  representa  tives  or by a  foreign
government or representative  thereof or by any corporation  organized under the
laws of a foreign  country.  As of the date of this opinion,  the Borrower holds
FCC-issued  common  carrier  radio  station  licenses  through its wholly  owned
subsidiaries.

                  To  determine  whether  foreign  ownership  in an FCC  license
holder (or in any  company  directly  or  indirectly  controlling  such  license
holder)  exceeds  the  applicable   foreign  ownership   limitations   described
immediately  above,  the FCC examines the percentage of foreign equity ownership
in the license holder (or in any company directly or indirectly controlling such
license  holder).  The FCC has also  stated  that it will  examine  the level of
capital  contributions made by foreign entities to determine whether the capital
contributions  of  such  foreign  investors  exceed  the  applicable   ownership
limitations  described  above. See Fox Television  Stations,  Inc., 78 Rad. Reg.
(P&F) 2d 1294  (1995)  ("Fox").  In Fox,  the FCC  relied  upon a United  States
Supreme Court case explaining "that capital stock 'is the capital upon which the
business is to be  undertaken,  and is represented by the property of every kind
acquired by the Company.'" Fox at P. 46, citing Wright v. Georgia R.R. & Banking
Co., 216 U.S. 420, 425 (1910) (emphasis added).

                  The FCC has not published any rules,  regulations,  decisions,
or orders determining the valuation of FCC licenses as capital contributions for
purposes of calculating  foreign ownership  interests as set forth in Fox. Based
on the attached  Officer's  Certificate  as to matters of fact, we have accepted
without  independent  verification  that the fair market  value of the  combined
capital  contributions  of  shareholders in the Borrower are as set forth in the
attached Officer's Certificate. Thus, applying the definition of "capital stock"
used by the FCC in Fox and provided

that the FCC were to accept the fair market  value of the  licenses as the basis
for determining the level of capital  contribution by Microwave Services,  Inc.,
Telcom-  DTS  Investors,  L.L.C.,  and Lynn  Forester,  the  Borrower  is not in
violation  of the  for  eign  ownership  provisions  of  Section  310(b)  of the
Communications Act

         This opinion is furnished to you solely for your benefit in  connection
with the closings under the Transaction  Documents occurring today and is not to

expressed herein are given as of the date of this opinion,  are based upon facts
in  existence as of the date of this  opinion,  and we assume no  obligation  to
advise you of any change in the foregoing opinion.

                  In rendering  the opinions set forth  herein,  I have examined

                  Collateral Agent;

                  4. the Collateral Agency and Intercreditor Agreement, dated as

                  5. copies of the Certificates of Incorporation  and By-laws of

                  appropriate as a basis for the opinions set forth below.

                  The  documents  referred to in items (1) through (4) above are
hereinaf ter referred to collectively as the "Transaction Documents."

                  I have  also  examined  original  or copies  identified  to my
satisfaction  of such  documents as I have deemed  necessary or appropriate as a
basis for the opinions set forth below.

                  In my  examination  I  have  assumed  the  genuineness  of all
signatures,  including endorsements,  the legal capacity of natural persons, the
authenticity  of all documents  submitted to me as originals,  the conformity to
original  documents  of all draft,  certified  or  photostatic  copies,  and the
authenticity  of the originals of such copies.  As to any facts material to this
opinion that I did not  independently  establish  or verify,  I have relied upon
statements  and  representations  of the Companies and their  officers and other
representatives, and of public officials.

                  I have  made  such  examination  of law as in my  judgment  is
necessary and appropriate for the purposes of this opinion.  I do not,  however,
purport to be an expert in, or  qualified  to  practice  under,  the laws of any
State other than the Com  monwealth  of  Pennsylvania.  I do not purport to pass
upon the laws of any jurisdic  tion other than the laws of the  Commonwealth  of
Pennsylvania.

                  Based  upon the  foregoing  and  subject  to the  limitations,
qualifica  tions,  exceptions  and  assumptions  set forth  herein,  I am of the
opinion that:

                  1. Each of the Companies has the power and authority,  and the
legal right, to own and operate its Property, if owned, to lease the Property it
operates as lessee and to conduct the business in which it is currently engaged;
except  where  failure to have such power,  authority  and legal right would not
result in a Material Adverse Effect.

                  2. Each Company is duly qualified as a foreign corporation and
in good standing under the laws of each jurisdiction where its ownership,  lease
or  operation  of  Property  or  the  conduct  of  its  business  requires  such
qualification, except where failure to be so qualified or in good standing would
not result in a Material Adverse Effect.

                  3. The  execution,  delivery  and  performance  by each of the
Companies  of the  Transaction  Documents to which each such Company is a party,
and the  borrowings  under  the  Credit  Agreement,  will  not (a)  violate  any
Requirement

                                        3

<PAGE>



of Law applicable to, or any Contractual Obligation of, any of the Companies; or
(b) result in, or require,  the creation or  imposition  of any Lien (other than
the Liens granted under the Transaction Documents and Liens permitted by Section
6.3 of the  Credit  Agreement)  upon  any  property  or  revenues  of any of the
Companies, except to the extent that such violations of (a) or (b) (individually
or in the aggregate) could not reasonably be expected to have a Material Adverse
Effect.

                  4. Except for the litigation  disclosed on Schedule 3.6 to the
Credit  Agreement,  no litigation,  investigation or proceeding of or before any
arbitrator or Governmental Authority is pending or, to my knowledge,  threatened
by or against the  Companies or any of their  respective  properties or revenues
(a)  with  respect  to any of  the  Transaction  Documents  or (b)  which  could
reasonably be expected to have a Material Adverse Effect.

                  This opinion is  furnished  exclusively  to you in  connection
with the above-referenced  transaction with the Companies, is provided on behalf
of the  Companies  in my capacity as General  Counsel of Teligent and the person
who  handles  legal  matters  for the  other  aforementioned  Companies,  and by
acceptance  hereof it is understood and agreed by any person relying hereon that
this opinion is made without personal recourse of any nature to me individually.
No party  other  than  the  addressees  or their  successors  and  assignees  is
authorized  or in any way  entitled  to rely on the  opinions  set forth  herein
without my express written consent.

The Chase Manhattan Bank
         as Administrative Agent
270 Park Avenue
New York, New York  10017

                  Re:      Teligent, Inc.

Ladies and Gentlemen:

         We have acted as special  communications counsel to The Chase Manhattan
Bank in connection  with the  preparation,  execution and delivery of the Credit
Agreement,  dated as of June 29, 1998 (the "Credit Agreement"),  among Teligent,
Inc.,  a  Delaware  corporation  (the  "Borrower"),  the  Lenders  [set forth on
Schedule III hereto] (the  "Lenders"),  Chase  Securities  Inc.,  Goldman  Sachs
Credit Partners L.P. and TD Securities  (USA) Inc., as Arrangers,  Goldman Sachs
Credit Partners L.P., as Syndication Agent,  Toronto Dominion (Texas),  Inc., as
Documentation  Agent, and The Chase Manhattan Bank, as Administrative Agent (the
"Administrative  Agent"); and in connection with the preparation,  execution and
delivery of the Guarantee  and  Collateral  Agreement,  dated June 29, 1998 (the
"Guarantee and Collateral  Agreement"),  made by the Borrower and the Restricted
Subsidiaries in favor of The Chase  Manhattan  Bank, as Collateral  Agent. We do
not represent the Borrower or its subsidiaries.

         This  opinion is being  furnished  pursuant  to  Section  4.1(m) of the
Credit Agreement.  Capitalized terms used and not otherwise defined herein shall
have the respective meanings set forth in the Credit Agreement.

         As special  communications  counsel  to the  Administrative  Agent,  we
address  only  matters  within the  jurisdiction  of the Federal  Communications
Commission  ("FCC")  pertaining  to the  regulations  of the Digital  Electronic
Message Service ("DEMS") under the Communications  Act of 1934, as amended,  and
the rules,  regulations,  and published and publicly available orders of the FCC
(collectively,  the  "Communications  Act")  applicable  to  the  DEMS  licenses
identified on Annex 1 hereto (the "FCC DEMS Licenses").

         Schedule III hereto
The Chase Manhattan Bank
         as Administrative Agent

Page 2

         The opinions  stated herein do not purport to cover areas of compliance
or any other matter that can reliably  determined  only through an inspection of
the  facilities,  work product,  records or operations of the Borrower or any of
its subsidiaries.  In rendering the opinions herein expressed,  we have assumed,
without  further  investigation,  the  accuracy  and  completeness  of the FCC's
publicly  available  licensing  records  at the  time of  their  examination  by
International  Transcription  Service ("ITS"),  and the absence of changes since
the date of such examination.

         Our  opinions  with  respect to the FCC DEMS  Licenses are based solely
upon a review of license  information  made available to us on June 23, 1998, by
ITS,  a private  entity  under  contract  with the FCC to make such  information
available to the public.  References in this opinion to the FCC's public records
refer, insofar as DEMS licensing matters may be involved,  solely to information
received  by us through  ITS from its  inspection  of FCC  licensing  records in
Gettysburg,  Pennsylvania, on June 23, 1998. Except as specifically described in
this paragraph, in connection with this opinion, we have not confirmed, nor have
we asked ITS to confirm,  licensing  information beyond the following:  the call
signs identified in Annex 1, the  corresponding  license  expiration  dates, and
identification  of the licensee.  Our opinions with respect to the effectiveness
of any  license  are  based  solely  upon the  confirmation  to us by ITS of the
expiration date for any such license. We advise you that the FCC's rules provide
for the automatic  cancellation of the FCC DEMS Licenses at an earlier date than
the scheduled expiration date if certain conditions, including the completion of
construction  by a specified date, are not met, and that the licensee of the FCC
DEMS Licenses may require further waivers,  modifications or other authorization
in connection with the particular circumstances of its business. We have made no
investigation  or other inquiry in connection  with this opinion with respect to
whether such conditions have been met or any such other  authorization or waiver
has been obtained;  and we have assumed that all such  conditions  have been met
and all other  authorizations  or waivers have been obtained with respect to the
FCC DEMS Licenses.

         Whenever any  statement in this opinion is indicated to be based on our
knowledge,   it  is  intended  to  signify  that,   during  the  course  of  our
representation  to  the  Administrative   Agent  in  Connection   herewith,   no
information has come to the attorneys in our firm involved in the preparation of
this  opinion  that  would  give  those  attorneys  actual  knowledge  that such
statement  is  incorrect.  Other  than our  above-described  review  of  certain
information  provided  by ITS,  we have  not  undertaken  any  investigation  to
determine the accuracy of any such statement.

         We do not purport to express opinions herein  concerning any laws other
than the  Communications  Act. Our opinions are limited  strictly to the matters
stated herein and no opinions may be inferred or are implied  beyond the matters
expressly stated herein.  We have assumed no obligation to advise you beyond the
opinions specifically expressed herein.

         Based upon our  examination  of the foregoing  disclosures,  documents,
records and matters of law and subject to the  qualifications,  assumptions  and
limitations set forth herein, we are of the opinion that:

         To our  knowledge,  based  upon the  above-based  review of the  public
records  of the FCC by ITS,  (i)  each of the FCC DEMS  Licenses  is held by the
licensee  identified in Annex 1, with such exceptions and  qualifications as may
be set forth in Annex 1 hereto;  and (ii) except as may be indicated in Annex 1,
each of the FCC DEMS Licenses set forth in Annex 1, assuming compliance with the
terms of each of such FCC DEMS  Licenses  and the rules and policies of the FCC,
is in effect.

         We advise you that on March 14,  1997,  the FCC  released a  Relocation
Order,  and on June 24, 1997, the Public Safety and Private  Wireless  Division,
Wireless  Telecommunications  Bureau of the FCC released a Modification Order of
the  Relocation  Order.  The  effect of these two orders  was to  relocate  DEMS
licenses from the 18GHz to the 24GHz band.  Several  parties have challenged the
FCC's  authority to issue these orders  without a notice and comment  rulemaking
proceedings,  and those challenges remain pending.  In addition,  a petition has
been filed  requesting that the FCC reallocate the 24MHz band for purposes other
DEMS. We advise you that the outcome of these  proceedings  remain uncertain and
that a  determination  adverse  to  the  Borrower  could  adversely  affect  the
operation of DEMS facilities under the FCC DEMS Licenses.

         The  opinions  set forth  herein  are given as of the date  hereof.  We
assume no obligation to advise you of changes which any thereafter be brought to
our attention. Our opinions are based on statutory and regulatory provisions and
judicial  decisions  in effect  at the date  hereof,  and we do not  opine  with
respect to any law, regulation, rule or governmental policy which may be enacted
or adopted after the date hereof,  nor do we assume any responsibility to advise
you of future changes on our opinion.

to any determination in such proceeding,  severally and respectively be restored
to their former positions and rights hereunder or thereunder with respect to the
Collateral  and the  Guarantee and in all other  respects,  and  thereafter  all
rights,  remedies and powers of the Collateral Agent shall continue as though no
such proceeding had been taken.

                  (d) To the extent  permitted by applicable laws, all rights of
action under this  Agreement,  the Guarantee  and the Security  Documents may be
enforced  by  the  Collateral  Agent  without  the  possession  of  any  Secured

Obligation or the production  thereof at any trial or other proceeding  relative
thereto.

                  2.4  Waiver  and  Estoppel.  (a) To the  extent  permitted  by
applicable  laws, the Borrower hereby agrees that it will not at any time in any
manner  whatsoever claim, or take the benefit or advantage of, any appraisement,
valuation, stay, extension,  moratorium,  turnover or redemption law, or any law
permitting it to direct the order in which the Collateral  shall be sold, now or
at any time hereafter in force, which may delay, prevent or otherwise affect the
performance  or  enforcement  of this  Agreement,  the Guarantee or any Security
Document and, to the extent  permitted by applicable  law, waives all benefit or
advantage of all such laws, and the Borrower  hereby  covenants that it will not
hinder,  delay or impede the  execution of any power  granted to the  Collateral
Agent in this Agreement,  the Guarantee or any Security Document but will suffer
and  permit  the  execution  of every  such  power as though no such law were in
force.

                  (b) To the extent  permitted by applicable laws, the Borrower,
on behalf  of  itself  and all who may  claim  through  or under it,  including,
without limitation,  any and all subsequent  creditors,  vendees,  assignees and
lienors,  waives and releases all rights to demand or to have any marshalling of
the  Collateral  upon any sale,  whether  made  under any power of sale  granted
herein or in any Security  Document or pursuant to judicial  proceedings or upon
any  foreclosure or any  enforcement of this Agreement or any Security  Document
and consents and agrees that all the  Collateral may at any such sale be offered
and sold as an entirety.

                  (c) The Borrower waives, to the extent permitted by applicable
law,  presentment,  demand,  protest and any notice of any kind (except  notices
explicitly required hereunder or under any Secured Instrument,  the Guarantee or
any Security Document) in connection with this Agreement,  the Guarantee and the
Security Documents, and any action taken by the Collateral Agent with respect to
the Collateral.

                  2.5  Limitation  on  Collateral  Agent's  Duty in  Respect  of
Collateral.  Beyond  its duties as to the  custody  thereof  expressly  provided
herein or in any Security Document and to account to the Secured Parties and the
Borrower  for moneys and other  property  received by it  hereunder or under any
Security Document,  the Collateral Agent shall not have any duty to the Borrower
or to the Secured  Parties as to any  Collateral in its possession or control or
in the  possession  or control of any of its agents or  nominees,  or any income
thereon or as to the  preservation  of rights against prior parties or any other
rights  pertaining  thereto,  except to treat such  Collateral in its possession
with the same degree of care as it affords its own  property  and in  accordance
with applicable laws.  Notwithstanding the foregoing, the Collateral Agent shall
be responsible and liable for any damages arising out of its gross negligence or
willful misconduct.

                  2.6  Limitation  by  Law.  All  rights,  remedies  and  powers
provided herein or in any Security  Document may be exercised only to the extent
that the exercise thereof does not violate any applicable  provision of law, and
all  the  provisions  hereof  are  intended  to be  subject  to  all  applicable
provisions  of law which may be  controlling  and to be  limited  to the  extent
necessary so that they will not render this Agreement invalid,  unenforceable in
whole or in

Secured  Obligation  or to  institute  suit  or to  obtain  a  judgment  for the
collection  of such Secured  Obligations  or to enforce any such  judgment on or

general  creditor in accordance  with the Secured  Instruments  to which it is a

                        COLLATERAL ACCOUNT; DISTRIBUTIONS

                  3.1 The  Collateral  Account.  (a) On the Effective Date there
shall be established  and, at all times  thereafter  until this Agreement  shall
have  terminated,  there shall be maintained  with the  Collateral  Agent at the
office  of  the  Collateral  Agent  located  at  __________________________,   a
collateral  account,  which shall be entitled  the  "Teligent,  Inc.  Collateral
Account" (the "Collateral Account").  The Collateral Account shall be subdivided
into two sub-accounts,  designated as the "Enforcement Proceeds Sub-Account" and
the "Asset Sale Proceeds Sub-Account" (each, a "Sub-Account").

                  (b) All moneys  which are  required by this  Agreement  or any
Security  Document to be  delivered  to the  Collateral  Agent while a Notice of
Enforcement  is in effect or which are received by the  Collateral  Agent or any
agent or nominee of the  Collateral  Agent in respect of the  Collateral  or the
Guarantee,  whether in connection with the exercise of the remedies  provided in
this  Agreement,  the Guarantee or any Security  Document or otherwise,  while a
Notice  of  Enforcement  is in  effect  shall be  deposited  in the  Enforcement
Proceeds Sub- Account and, in each case, held by the Collateral Agent as part of
the Collateral and applied in accordance with the terms of this Agreement.  Upon
the cancellation of each effective Notice of Enforcement  pursuant to subsection
2.1(c),  the  Collateral  Agent  shall  (subject  to the  payment of the amounts
described  in the first  clause of  subsection  3.4(a) and the last  sentence of
subsection  3.1(c))  cause  all funds on  deposit  in the  Enforcement  Proceeds
Sub-Account to be paid over to the Borrower;  provided, however, that funds (the
"Hold-Back  Funds")  in an  amount  equal to the sum of (x) the  amount of funds
transferred  to the  Enforcement  Proceeds  Sub-Account  pursuant  to the second
sentence of  subsection  3.1(c) and (y) the amount of funds that would have been
deposited in the Asset Sale Proceeds  Sub-Account but for the  effectiveness  of
any Notice of Enforcement, together with all interest and income on such

                                                                              12



amounts,  shall  be  deposited  in  the  Asset  Sale  Proceeds  Sub-Account  for
application in accordance with the terms of Section 3 as if such Hold-Back Funds
had been  deposited in such Asset Sale Proceeds  Sub-Account  (i) in the case of
funds in an amount equal to funds referred to in (x) above,  since the time they
were originally deposited in the Asset Sale Proceeds Sub-Account and (ii) in the
case of funds in an amount  equal to the funds  referred to in (y) above,  since
the time they would have been  deposited in the Asset Sale Proceeds  Sub-Account
if no such Notice of Enforcement had become effective.

                  (c) All moneys  constituting  proceeds  of an Asset Sale which
are  delivered  to the  Collateral  Agent as required by the  provisions  of any
Secured Instrument shall be deposited in the Asset Sale Proceeds Sub-Account and
held by the  Collateral  Agent and applied in accordance  with the terms of this
Agreement.  Upon the receipt by the Collateral Agent of a Notice of Enforcement,
all  amounts  on  deposit  in the  Asset  Sale  Proceeds  Sub-Account  shall  be
transferred to the Enforcement Proceeds Sub-Account;  provided, that all amounts
so  transferred  from the Asset Sale  Proceeds  Sub-Account  to the  Enforcement
Proceeds  Sub-  Account,  together with all interest and income on such amounts,
shall be returned to the Asset Sale Proceeds Sub-Account under the circumstances
set forth in the proviso in subsection 3.1(b).

                  (d) The Borrower may, by delivery to the  Collateral  Agent of
an Asset Sale Proceeds  Release  Request,  at any time within 360 days after the
deposit of any funds in the Asset Sale Proceeds  Sub-Account,  request a release
of such funds from the Asset Sale  Proceeds  Sub-Account  for use in funding the
acquisition  of assets  in  accordance  with the  applicable  provisions  of the
Secured  Instruments.  If no Notice of  Enforcement  is in effect on the date on
which  such  funds are  requested  to be  released  pursuant  to such Asset Sale
Proceeds  Release  Request,  the Collateral  Agent shall release to the Borrower
funds from the Asset Sale Proceeds  Sub-Account  in  accordance  with such Asset
Sale Proceeds  Release  Request.  To effect such release,  the Collateral  Agent
shall  liquidate  such  investments  of such  funds in the Asset  Sale  Proceeds
Sub-Account as shall be specified in such Asset Sale Proceeds Release Request.

                  (e)  If  any  funds  deposited  in  the  Asset  Sale  Proceeds
Sub-Account have not been withdrawn  therefrom within 360 days after the date of
deposit  thereof,  such  funds  may  thereafter  be  withdrawn  only  (i) by the
Collateral  Agent while a Notice of Enforcement is in effect as  contemplated by
the  second  sentence  of  subsection  3.1(c)  to  be  distributed  pursuant  to
subsection 3.4 or (ii) pursuant to an Asset Sale Proceeds Prepayment Request, as
provided in subsection 3.1(f).

                  (f)  The  Borrower  may,  at  any  time,  by  delivery  to the
Collateral  Agent of an Asset Sale  Proceeds  Prepayment  Request,  request  the
Collateral Agent to withdraw funds from the Asset Sale Proceeds  Sub-Account and
transfer such funds to Secured  Parties for  application by such Secured Parties
toward prepayment of Secured Obligations in the manner specified by the relevant
Secured  Instruments.  If no Notice of  Enforcement  is in effect on the date on
which  such  funds are  requested  to be  released  pursuant  to such Asset Sale
Proceeds

                                                                              13



Prepayment  Request,  the  Collateral  Agent shall transfer funds from the Asset
Sale Proceeds  Sub-Account to Secured Parties in accordance with such Asset Sale
Proceeds Prepayment Request.

                  3.2  Control  of  Collateral  Account.  All  right,  title and
interest in and to the Collateral  Account shall vest in the Collateral Agent on
behalf of the Secured  Parties,  and funds on deposit in the Collateral  Account
shall constitute part of the Collateral. The Collateral Account shall be subject
to the sole and exclusive dominion and control of the Collateral Agent.

                  3.3 Investment of Funds Deposited in Collateral  Account.  The
Collateral  Agent shall invest and reinvest  moneys on deposit in the Collateral
Account at any time in Cash Equivalents; provided that the Borrower may (so long
as no  Notice  of  Enforcement  shall be in  effect)  specify  the  category  or
categories of  investments  specified in the  definition of Cash  Equivalents in
Section 1 in which  funds on  deposit in the Asset Sale  Proceeds  Sub-  Account
shall be invested and may specify the  maturities  (not in any event longer than
the maturities specified in such definition) of such investments;  provided that
the Borrower or the Collateral  Agent, as applicable,  shall, to the extent that
the timing of distributions  to be made from the Collateral  Account is known or
can be  reasonably  anticipated,  select  investments  for amounts equal to such
distributions  that mature beyond the maturities  specified in the definition of
Cash Equivalents, but prior to the anticipated dates of such distributions.  All
such investments of funds in any  Sub-Account,  the interest and income received
thereon and the net proceeds realized on the sale or redemption thereof shall be
held in such Sub-Account as part of the Collateral.

                  3.4  Application  of  Moneys.  (a)  All  moneys  held  by  the
Collateral  Agent in the Collateral  Account or received by the Collateral Agent
while a Notice of  Enforcement is in effect shall,  to the extent  available for
distribution  (it being  understood  that the  Collateral  Agent  may  liquidate
investments prior to maturity to make a distribution pursuant to this subsection
3.4),  be  distributed  (subject to the  provisions  of  subsection  3.5) by the
Collateral Agent on each Distribution Date as follows:

               First: to the Collateral  Agent, in an amount equal to any unpaid
          costs or expenses of the  Collateral  Agent incurred in performing its
          duties hereunder and under the Security Documents and Guarantee;

               Second:  to the Secured  Parties,  in an amount equal to all sums
          which constitute Secured Obligations then held by the Secured Parties,
          including  without  limitation the unpaid principal or face amount of,
          and unpaid  interest on and other charges,  if any, in respect of, the
          Secured  Obligations then  outstanding  whether or not due and payable
          and  the  costs  and  expenses  of  the  Secured   Parties  and  their
          representatives  which are due and payable under the relevant  Secured
          Instruments  and  which  constitute  Secured  Obligations  as of  such
          Distribution Date, and, if such moneys shall be insufficient to

                                                                              14



          pay  such  sums in  full,  then  ratably  to the  Secured  Parties  in
          proportion to such sums; and

               Third:  any surplus then remaining  shall be paid to the Borrower
          or its successors or assigns or to whomsoever may be lawfully entitled
          to  receive  the  same or as a court  of  competent  jurisdiction  may
          direct.

                  (b)  The   Collateral   Agent  shall  make  all  payments  and
distributions  under  this  subsection  3.4:  (i) on  account  of Bank  Facility
Obligations,  to the Administrative  Agent, for redistribution or application in
accordance with the provisions of the Credit  Agreement,  (ii) on account of any
Vendor Facility Obligations owing to any Vendor Facility Secured Party for which
there  is  a  Vendor  Facility  Agent,  to  such  Vendor  Facility  Agent,   for
redistribution  or application in accordance with the provisions of the relevant
Secured Instrument, (iii) on account of any Hedging Agreement Obligations or L/C
Obligations, directly to the Holder of such Hedging Agreement Obligations or L/C
Obligations,  as the case may be, and (iv) on  account  of  Secured  Obligations
owing to any Unrepresented Holder, directly to such Unrepresented Holder.

                  3.5 Amounts Held for Contingent  Secured  Obligations.  In the
event any Holder or Holder  Representative  shall receive any moneys pursuant to
subsection 3.4 in respect of the contingent  portion of the outstanding  Secured
Obligations,  then such  Holder or  Holder  Representative,  as the case may be,
shall invest such moneys in Cash Equivalents  maturing within 90 days after they
are  acquired  by such Holder or Holder  Representative  and shall hold all such
amounts so distributable, and all such investments and the net proceeds thereof,
in trust until (i) all or part of such contingent claim shall have become fixed,
in which case such Holder or Holder  Representative,  as the case may be,  shall
apply to the payment of such fixed claim from such  investments and the proceeds
thereof an amount  equal to such fixed  claim,  and shall  promptly  give notice
thereof to the  Borrower  and the  Collateral  Agent or (ii) all or part of such
contingent  claim  shall  have been  extinguished,  whether  as the result of an
expiration  without drawing of any letter of credit,  payment of amounts secured
or covered by any letter of credit other than by drawing thereunder,  payment of
amounts  covered by any  guarantee  or  otherwise,  in which case such Holder or
Holder  Representative,  as the  case  may be,  shall,  as  soon as  practicable
thereafter,  notify the Borrower and the Collateral  Agent and shall  distribute
from such investments,  and the proceeds thereof, an amount equal to the portion
of contingent  claim which has been  extinguished  together with interest earned
thereon from the date first  invested  until so  distributed,  to the Collateral
Agent for deposit in the Collateral  Account and  application in accordance with
the provisions of subsection 3.4.

                  3.6   Application   of   Moneys    Distributable   to   Holder
Representatives.  If at  any  time  any  moneys  collected  or  received  by the
Collateral Agent pursuant hereto are distributable pursuant to subsection 3.4 to
a Holder  Representative,  and if such Holder  Representative  shall  notify the
Collateral Agent in writing that no provision is made under the relevant Secured
Instrument for the application by such Holder  Representative of moneys (whether
because the Secured  Obligations  issued under such Secured  Instrument have not
become due and payable



<PAGE>


                                                                              15



or otherwise) and that such Secured Instrument does not effectively  provide for
the receipt and the holding by such Holder Representative of such moneys pending
the  application  thereof,  then the  Collateral  Agent,  after  receipt of such
notification,  shall invest such amounts in Cash Equivalents  maturing within 90
days after they are  acquired  by the  Collateral  Agent and shall hold all such
amounts so  distributable  and all such investments and the net proceeds thereof
in trust solely for such Holder Representative (in its capacity as such) and for
no other purpose until such time as such Holder  Representative shall request in
writing the delivery thereof by the Collateral Agent for application pursuant to
such  Secured  Instrument;  if no  such  request  is  made  on or  prior  to the
termination of this Agreement or the relevant Secured Instrument under which the
Holder  Representative  is acting,  all such  amounts  (including  interest  and
profits) shall be paid to the Borrower.

                  3.7   Collateral   Agent's   Calculations.   In   making   the
determinations and allocations  required by subsection 3.4, the Collateral Agent
may rely upon a certificate executed and supplied by the Holder  Representatives
or (in the case of Hedging  Agreement  Obligations or other Secured  Obligations
for which there is no Holder Representative) the Holders, as the case may be, as
to the amounts  payable with respect to Secured  Obligations,  all in accordance
with subsection 7.4, and the Collateral  Agent shall have no liability to any of
the Secured Parties for actions taken in reliance on such information  provided,
that nothing in this sentence shall prevent the Borrower from contesting in good
faith any amounts  claimed by any Secured Party in any  information so supplied;
and  provided  further,  however,  that if any  Secured  Party  receives  on any
Distribution  Date an  amount  pursuant  to  subsection  3.4(a) in excess of the
amount to which it was entitled to receive on such Distribution Date pursuant to
such  subsection  3.4(a) as a result  of any such  certificate  overstating  the
amount of the Secured  Obligations  held by such  Secured  Party (or the Secured
Obligations  held by all the Secured  Parties under any Facility with respect to
which such Secured  Party is a Holder),  then such Secured  Party (by becoming a
Holder of Secured  Obligations  and  accepting  the benefits of this  Agreement)
shall pay such excess to the Collateral Agent for application in accordance with
subsection   3.4(a)  as  soon  as  practicable   after  the  existence  of  such
overstatement  shall  have  been  determined.  All  distributions  made  by  the
Collateral  Agent  pursuant to subsection 3.4 shall be (subject to any decree of
any  court  of  competent  jurisdiction  and to  the  proviso  in the  preceding
sentence)  final,  and the Collateral  Agent shall have no duty to inquire as to
the  application  by  any  Holder  or  Holder   Representative  of  any  amounts
distributed to them. By accepting the benefits of this  Agreement,  the Security
Documents and the Guarantee, each Secured Party and Holder Representative agrees
to act in accordance  with this  Agreement and not take any action  inconsistent
herewith.

                         ADDITIONAL SECURED OBLIGATIONS;
                  ADDITIONAL COLLATERAL; ADDITIONAL GUARANTORS

the Collateral Agent a true copy of the Credit Agreement and executed  originals
of the Initial Security Documents and the Guarantee.

                  4.2 Additional Secured Obligations. The Borrower may from time
to  time  designate   Permitted   Additional  Secured   Obligations  as  Secured
Obligations  hereunder by (a) delivering to the  Collateral  Agent an Additional
Secured Obligations  Designation in respect of such Permitted Additional Secured
Obligations   describing  such  Permitted  Additional  Secured  Obligations  and
specifying  whether  such  Permitted   Additional   Secured   Obligations  shall
constitute  Vendor  Facility  Obligations or Hedging  Agreement  Obligations and
attaching thereto a true and complete copy of all agreements  (together with all
schedules,   exhibits,  annexes,  appendices  and  other  attachments  thereto),
including but not limited to the  applicable  Secured  Instruments,  relating to
such Permitted  Additional Secured Obligations to which the Borrower is a party,
and (b) delivering to the Collateral  Agent such evidence as it shall reasonably
request that such obligations are Permitted Additional Secured Obligations. Upon
completion  of the  actions  described  clauses  (a)  and  (b) of the  preceding
sentence,  but  subject to the  following  sentence,  the  Permitted  Additional
Secured   Obligations   designated  by  such  Additional   Secured   Obligations
Designation shall constitute  Secured  Obligations and the Holders thereof shall
constitute  Secured  Parties  hereunder  and  shall be  bound by the  provisions
hereof.  Notwithstanding  anything herein to the contrary, in no event shall any
indebtedness or other obligations of the Borrower constitute  Additional Secured
Obligations   hereunder  if  the  designation  of  such  indebtedness  or  other
obligations as Additional  Secured  Obligations would be in contravention of any
Secured  Instrument,  and any purported  designation of any such indebtedness or
other obligations of the Borrower as Additional Secured Obligations in violation
of any Secured Instrument shall be null and void and of no force or effect.

                  4.3 Additional Collateral;  Additional Security Documents. The
Borrower  will  from  time to time  take the  actions  required  by the  Secured
Instruments  and  Security  Documents  to perfect the  security  interest of the
Collateral  Agent created  pursuant to the Initial  Security  Documents  then in
effect  in  terms of  Collateral  hereafter  acquired  by the  Borrower  and its
Restricted  Subsidiaries.  The Borrower may from time to time provide Additional
Collateral to the Collateral Agent pursuant to Additional  Security Documents by
delivering to the  Collateral  Agent an  Additional  Collateral  Designation  in
respect of such Additional  Collateral.  In connection  with such delivery,  the
Borrower shall fulfill the requirements of the Credit Agreement or other Secured
Instrument relating to the delivery of such Additional Collateral.

Possessory Collateral that is or may be in the possession of the Borrower or any
of its  Subsidiaries,  to the extent the  Borrower  is  required to do so by any
Security  Document or Secured  Instrument and as provided in Section 8.14 of the
Guarantee and Collateral Agreement.

Unrepresented Holders, Etc.. The Borrower shall deliver to the Collateral Agent,
from time to time as may be reasonably  requested by the Collateral Agent (which
request shall be made by the Collateral Agent at the reasonable direction of any
Secured Party),  (i) with respect to all Secured  Obligations other than Hedging
Agreement  Obligations,  a list,  setting forth as of a specified  date not more
than 30  days  prior  to the  date of such  delivery,  of the  aggregate  unpaid

Agent  pursuant to subsection  7.8. The  obligations  of the Borrower under this
subsection  shall  survive  the  termination  of the  other  provisions  of this
Agreement and the resignation or removal of the Collateral Agent.

                  5.4 Stamp and Other  Similar  Taxes.  The  Borrower  agrees to
indemnify and hold harmless the Collateral Agent and each Secured Party from any
present or future claim for liability for any stamp or any other similar tax and
any penalties or interest with respect thereto, which may be assessed, levied or
collected by any  jurisdiction in connection  with this Agreement,  any Security
Document, any Guarantee or any Collateral. The obligations of the Borrower under
this subsection  shall survive the  termination of the other  provisions of this
Agreement and the resignation or removal of the Collateral Agent.

                  5.5 Filing Fees, Excise Taxes, Etc. The Borrower agrees to pay
or to  reimburse  the  Collateral  Agent  for any and all  payments  made by the

determined  to be  payable  in respect of the  execution  and  delivery  of this
Agreement,  the Guarantee and the Security  Documents.  The  obligations  of the
Borrower  under this  subsection  shall  survive  the  termination  of the other
provisions of this  Agreement and the  resignation  or removal of the Collateral
Agent.

                  5.6  Indemnification.  The Borrower agrees to pay,  indemnify,
and hold the Collateral Agent harmless from and against any and all liabilities,
obligations,  losses,  damages,  penalties,  actions,  judgments,  suits, costs,
expenses  (including,  without limitation,  the fees and disbursements and other
charges of  counsel)  or  disbursements  of any kind or nature  whatsoever  with
respect to the execution, delivery, enforcement,  performance and administration
of this Agreement, the Guarantee and the Security Documents, unless arising from
the gross negligence or willful misconduct of the indemnified party,  including,
without  limitation,  indemnification of the Collateral Agent for liabilities of
the Collateral  Agent for the net amount of taxes (after taking into account any
deduction,  credit or other tax reduction or benefit  available by reason of the
imposition of such tax) in any  jurisdiction in which the Collateral Agent would
not  otherwise  be subject to tax except  solely by reason of acting  under this
Agreement,  the Guarantee or any Security Document (directly or through agents),
provided that such  indemnification for taxes (a) shall apply only in respect of
taxes attributable to the performance of the Collateral  Agent's  obligations as
Collateral  Agent hereunder or under any Guarantee or Security  Document and (b)
shall in no event cover any taxes imposed upon the Collateral Agent with respect
to or measured by its net income or profits.

         In any suit, proceeding or action brought by the Collateral Agent under
or with respect to any contract,  agreement, interest or obligation constituting
part  of the  Collateral  for  any  sum  owing  thereunder,  or to  enforce  any
provisions  thereof in accordance with the provisions hereof and of the Security
Documents,  the Borrower  will save,  indemnify  and keep the  Collateral  Agent
harmless from and against all expense,  loss or damage suffered by reason of any

arising out of any other agreement,  indebtedness or liability at any time owing
to or in favor of such  obligor  or its  successors  from  the  Borrower  unless
arising out of the gross  negligence  or willful  misconduct  of the  Collateral
Agent, and all such obligations of the Borrower shall be and remain  enforceable
against and only against the Borrower and shall not be  enforceable  against the
Collateral   Agent.   The  agreements  in  this  subsection  shall  survive  the
termination  of the other  provisions of this  Agreement and the  resignation or
removal of the Collateral Agent.

                  5.7  Further  Assurances.  At any time and from  time to time,
whether  or not a Notice of  Enforcement  shall be in effect,  upon the  written
request  of the  Collateral  Agent,  and at the  expense  of the  Borrower,  the
Borrower will promptly execute and deliver any and all such further  instruments
and documents and take such further  action as the Collateral  Agent  reasonably
requests  to  obtain  the  full  benefits  of this  Agreement  and the  Security
Documents  and of the rights and powers  herein and therein  granted or to cause
any assets  required  under a Secured  Instrument  to be subject to a  perfected
security interest of the Collateral Agent to be so subject,  including,  without
limitation,  the filing of any financing or  continuation  statements  under the
Uniform  Commercial Code in effect in any jurisdiction with respect to the liens
and security interests granted under the Security  Documents.  The Borrower also
hereby  authorizes the Collateral  Agent to sign and to file any such documents,
instruments or financing or continuation statements without the signature of the
Borrower  to  the  extent  permitted  by  applicable  law,  but in no way is the
Collateral Agent obligated to do so.


                                    SECTION 6
                              POSSESSION AND USE OF
                          COLLATERAL; PARTIAL RELEASES

                  6.1 Use  Prior to  Notice  of  Enforcement.  (a) So long as no
Notice of Enforcement  is in effect,  the Borrower shall have the right (subject
to compliance  with subsection  6.1(b)):  (i) to remain in possession and retain
exclusive  control of the  Collateral  (except any Possessory  Collateral)  with
power freely and without  hindrance on the part of the  Collateral  Agent or the
Secured Parties to operate, manage, develop, use and enjoy the Collateral and to
receive the rents, issues, tolls, profits, royalties,  revenues and other income
thereof  (including,  in the case of Collateral which consists of Pledged Stock,
to receive all  distributions  in respect of the  Pledged  Stock and to vote the
Pledged Stock and exercise any and all rights attached  thereto,  subject to the
Security Documents), and (ii) to sell or otherwise dispose of, free and clear of
the lien and security interest created by the Security Documents, any Collateral
if such sale or other disposition is not prohibited by any Secured Instrument or
Security  Document.  The  Collateral  Agent  shall have no duty to  monitor  the
exercise by the Borrower of its rights under this subsection.

                  (b) If a Notice of  Enforcement  is in effect,  cash  Proceeds
received  by the  Borrower  in  connection  with any Asset  Sale in  respect  of
Collateral shall be promptly deposited in the Enforcement Proceeds  Sub-Account.
Any such Proceeds received by the

                                                                              20



Borrower when a Notice of Enforcement is in effect shall be held by the Borrower
in trust for the Collateral  Agent,  shall be segregated from other funds of the
Borrower and shall,  forthwith  upon receipt by the Borrower,  be turned over to
the  Collateral  Agent,  in the same  form as  received  by the  Borrower  (duly
indorsed to the Collateral  Agent,  if required) for deposit in the  Enforcement
Proceeds Sub-Account.

                  6.2 Releases.  (a) Asset Sales in respect of Collateral  which
are permitted by subsection 6.1 shall not require any written or oral release or
consent of the Collateral Agent. Nevertheless, the Borrower may request that the
Collateral  Agent  execute  and  deliver to the  Borrower  or any  purchaser  of
Collateral a written  release,  disclaimer  or  quitclaim in form and  substance
reasonably  satisfactory to the Borrower of the Collateral  Agent's  interest in
any  Collateral  under  the  Security  Documents,  and such  purchaser  shall be
entitled to rely conclusively on such release, discharge,  termination, consent,
disclaimer or quitclaim.  Such request shall be in writing,  shall  describe the
property to be released in  reasonable  detail,  and shall state that such sale,
transfer  or  disposition  is  in  compliance  with  the  requirements  of  such
subsection  6.1,  that the  proceeds  of such  transaction  have been or will be
applied  as set  forth  in the  relevant  provisions,  if any,  of each  Secured
Instrument and that subsection 6.2(b) has been complied with in full.

                  (b) If it is a condition of the release of any Collateral from
the security interest under any Security Document or Secured Instrument that the
Collateral  Agent be  granted a first  priority  lien or  security  interest  in
additional  property to be held as Collateral  pursuant to this Agreement,  then
the Collateral Agent shall be granted such lien or security interest prior to or
concurrently  with the  delivery to the Borrower of any such  Collateral  or any
release, discharge,  termination, consent, disclaimer or quitclaim in connection
therewith.  The grant of such lien or security interest shall be effected by (i)
delivery  to  the  Collateral  Agent  of an  Additional  Collateral  Designation
pursuant to subsection 4.3 and (ii)  fulfilling the  requirements  of subsection
4.3 with respect thereto.

                  (c) If  any  Collateral  which  is  being  sold  or  otherwise
disposed of pursuant to this Section 6 is in the  possession  of the  Collateral
Agent or any agent or nominee  thereof,  the  Collateral  Agent or such agent or
nominee  shall  promptly  upon  the  delivery  to  the  Collateral  Agent  of  a
certificate of a Responsible  Officer (to the effect that such sale, transfer or
disposition is in compliance with the  requirements of such subsection 6.1, that
the  proceeds of such  transaction  have been or will be applied as set forth in
the relevant provisions,  if any, of each Secured Instrument and that subsection
6.2(b) has been complied with in full), together with such other evidence as the
Collateral  Agent shall  reasonably  require,  release  such  Collateral  to the
Borrower in connection with such Asset Sale.

                  (d)  The  notices,   statements,   directions,   evidence  and
certificates  requested  under  or  required  by this  subsection  shall be full
authority for and direction to the  Collateral  Agent to execute and deliver the
releases, discharges,  terminations, consents, disclaimers, quitclaims and other
instruments referred to in this subsection and the Collateral Agent shall

                                                                              21



promptly  (and in any event  within five  business  days) do so. The  Collateral
Agent in so doing  shall  have no  liability  to any  Person  other than for its
willful misconduct or gross negligence.

                  6.3   Insurance   and   Condemnation   Proceeds;   Liquidating
Dividends.  Any insurance proceeds,  any Proceeds from the exercise of rights of
eminent domain or condemnation and any liquidating  dividends paid in respect of
Pledged Equity  Securities  received by the Borrower or the Collateral  Agent in
respect of  Collateral  shall be treated as cash Proceeds  received  pursuant to
subsection  6.1(b)  and  shall,  if a Notice of  Enforcement  is in  effect,  be
deposited  in the  Collateral  Account,  and if no Notice of  Enforcement  is in
effect,  such  amounts  shall be  delivered  to the  Borrower  unless  otherwise
required by any Secured Instrument or Security Document.



                                    SECTION 7
                              THE COLLATERAL AGENT

                  7.1  Appointment.   Each  Secured  Party  hereby   irrevocably
designates and appoints the Collateral  Agent as the agent of such Secured Party
under this Agreement, the Security Documents and the Guarantee, and each Secured
Party  irrevocably  authorizes the Collateral  Agent, in such capacity,  to take
such action on its behalf under the provisions of this  Agreement,  the Security
Documents  and the Guarantee and to exercise such powers and perform such duties
as are  expressly  delegated  to the  Collateral  Agent  by the  terms  of  this
Agreement,  the Security  Documents and the Guarantee,  together with such other
powers as are reasonably  incidental  thereto.  Notwithstanding any provision to
the contrary  elsewhere in this Agreement,  the Collateral  Agent shall not have
any duties or responsibilities,  except those expressly set forth herein, or any
fiduciary  relationship  with  any  Secured  Party,  and no  implied  covenants,
functions,  responsibilities,  duties,  obligations or liabilities shall be read
into this Agreement,  the Security Documents or the Guarantee or otherwise exist
against the Collateral Agent.

                  7.2 Delegation of Duties. The Collateral Agent may execute any
of its duties under this Agreement,  the Security Documents and the Guarantee by
or  through  agents  or  attorneys-in-fact  and shall be  entitled  to advice of
counsel  concerning all matters  pertaining to such duties. The Collateral Agent
shall not be  responsible  for the  negligence  or  misconduct  of any agents or
attorneys in-fact selected by it with reasonable care.

                  7.3 Exculpatory  Provisions.  Neither the Collateral Agent nor
any  of  its  officers,  directors,  employees,  agents,   attorneys-in-fact  or
affiliates  shall be (i) liable for any action  lawfully  taken or omitted to be
taken by it or such  Person  under or in  connection  with this  Agreement,  the
Security  Documents  or the  Guarantee  (except  to the  extent  that any of the
foregoing  resulted  from its or such  Person's own gross  negligence or willful
misconduct) or (ii)  responsible in any manner to any of the Secured Parties for
any recitals, statements,  representations or warranties made by the Borrower or
any of its Subsidiaries or any officer


<PAGE>


                                                                              22



thereof contained in this Agreement,  the Security Documents or the Guarantee or
in any certificate,  report, statement or other document referred to or provided
for in, or received by the Collateral  Agent under or in connection  with,  this
Agreement,  the Security Documents or the Guarantee or for the value,  validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement, the
Security Documents or the Guarantee or for any failure of the Borrower or any of
its  Subsidiaries  party  thereto  to  perform  its  obligations   hereunder  or
thereunder.  The  Collateral  Agent  shall  not be under any  obligation  to any
Secured Party to ascertain or to inquire as to the  observance or performance of
any of the  agreements  contained  in, or  conditions  of, this  Agreement,  the
Security  Documents or the  Guarantee,  or to inspect the  properties,  books or
records of the Borrower or any of its Subsidiaries.

                  7.4 Reliance by  Administrative  Agent.  The Collateral  Agent
shall be entitled to rely,  and shall be fully  protected  in relying,  upon any
instrument,  writing,  resolution,  notice,  consent,  certificate,   affidavit,
letter, telecopy, telex or teletype message,  statement, order or other document
or  conversation  believed  by it to be  genuine  and  correct  and to have been
signed,  sent or made by the  proper  Person  or  Persons  and upon  advice  and
statements  of legal  counsel  (including,  without  limitation,  counsel to the
Borrower or any of its Subsidiaries),  independent accountants and other experts
selected by the Collateral  Agent. The Collateral Agent shall be fully justified
in failing or refusing to take any action  under this  Agreement,  the  Security
Documents  or the  Guarantee  unless  it shall  first  receive  such  advice  or
concurrence of the  Administrative  Agent or the Required  Secured Parties as it
deems  appropriate or it shall first be indemnified to its  satisfaction  by the
Secured  Parties against any and all liability and expense which may be incurred
by it by reason of taking or continuing to take any such action.  The Collateral
Agent shall in all cases be fully  protected in acting,  or in  refraining  from
acting,  under this  Agreement,  the  Security  Documents  and the  Guarantee in
accordance with a request of the Required Secured Parties,  and such request and
any action  taken or failure to act pursuant  thereto  shall be binding upon all
the Secured Parties and all future holders of the Secured Obligations.

                  7.5 Non-Reliance on Collateral Agent or Other Secured Parties.
Each Secured Party expressly  acknowledges that neither the Collateral Agent nor
any  of  its  officers,  directors,  employees,  agents,   attorneys-in-fact  or
affiliates have made any  representations or warranties to it and that no act by
the Collateral Agent hereafter taken, including any review of the affairs of the
Borrower or any of its  Subsidiaries or any affiliate of a Loan Party,  shall be
deemed to constitute any  representation  or warranty by the Collateral Agent to
any Secured Party. Each Secured Party represents to the Collateral Agent that it
has,  independently  and without reliance upon the Collateral Agent or any other
Secured  Party,  and based on such  documents and  information  as it has deemed
appropriate,  made its own  appraisal of and  investigation  into the  business,
operations,  property, financial and other condition and creditworthiness of the
Borrower and its  affiliates  and made its own decision to extend  credit to the
Borrower and enter into this Agreement.  Each Secured Party also represents that
it will,  independently  and without  reliance upon the Collateral  Agent or any
other Secured  Party,  and based on such  documents and  information as it shall
deem  appropriate  at the  time,  continue  to  make  its own  credit  analysis,
appraisals and decisions in taking or not taking action under this


<PAGE>


                                                                              23



Agreement,   the  Security  Documents  and  the  Guarantee,  and  to  make  such
investigation  as it  deems  necessary  to  inform  itself  as to the  business,
operations,  property, financial and other condition and creditworthiness of the
Borrower and its  affiliates.  Except for notices,  reports and other  documents
expressly  required to be  furnished  to the Secured  Parties by the  Collateral
Agent hereunder,  the Collateral Agent shall not have any duty or responsibility
to provide any Secured Party with any credit or other information concerning the
business, operations, property, condition (financial or otherwise), prospects or
creditworthiness  of the  Borrower  or any  affiliate  which  may come  into the
possession of the Collateral Agent or any of its officers, directors, employees,
agents, attorneys-in-fact or affiliates.

                  7.6  Indemnification.  The Secured  Parties agree to indemnify
the  Collateral  Agent in its capacity as such (to the extent not  reimbursed by
the Borrower  and without  limiting  the  obligation  of the Borrower to do so),
ratably according to the amounts of Secured Obligations held by them on the date
on which indemnification is sought under this Section (or, if indemnification is
sought after the date upon which the Secured Obligations shall have been paid in
full, ratably in accordance with the amounts of Secured Obligations held by them
immediately  prior to such  date),  from and  against  any and all  liabilities,
obligations,  losses,  damages,  penalties,  actions,  judgments,  suits, costs,
expenses  or  disbursements  of any  kind  whatsoever  which  may  at  any  time
(including,  without limitation, at any time following the payment of the Loans)
be imposed on, incurred by or asserted  against the Collateral  Agent in any way
relating to or arising out of this  Agreement,  the  Security  Documents  or the
Guarantee or any documents  contemplated  by or referred to herein or therein or
the transactions  contemplated  hereby or thereby or any action taken or omitted
by the  Collateral  Agent  under or in  connection  with  any of the  foregoing;
provided that no Secured Party shall be liable for the payment of any portion of
such liabilities,  obligations,  losses, damages, penalties, actions, judgments,
suits,  costs,  expenses  or  disbursements  which  are  found  by a  final  and
nonappealable  decision of a court of competent  jurisdiction  to have  resulted
from  the  Collateral  Agent's  gross  negligence  or  willful  misconduct.  The
agreements  in  this  subsection  shall  survive  the  payment  of  the  Secured
Obligations and all other amounts payable hereunder.

                  7.7  Collateral   Agent  in  Its  Individual   Capacity.   The
Collateral  Agent and its affiliates may make loans to, accept deposits from and
generally  engage  in any  kind of  business  with  the  Borrower  or any of its
affiliates as though the Collateral  Agent were not the Collateral  Agent.  With
respect to Secured  Obligations  held by it, the Collateral Agent shall have the
same rights and powers  under this  Agreement,  the Security  Documents  and the
Guarantee  as any Secured  Party and may exercise the same as though it were not
an Agent, and the terms "Secured Party" and "Secured  Parties" shall include the
Collateral Agent in its individual capacity.

                  7.8  Successor  Agent.  The  Collateral  Agent  may  resign as
Collateral  Agent upon 30 days' notice to the Secured  Parties and the Borrower.
If the Collateral  Agent shall resign as Collateral  Agent under this Agreement,
the Security  Documents and the  Guarantee,  then the Required  Secured  Parties
shall appoint from among the Secured  Parties a successor  collateral  agent for
the Secured Parties, which successor collateral agent shall (unless an Event

                                                                              24



of Default  under  Section  7(a) or Section 7 (f) of the Credit  Agreement  with
respect to the Borrower  shall have  occurred and be  continuing)  be subject to
approval by the Borrower (which  approval shall not be unreasonably  withheld or
delayed), whereupon such successor agent shall succeed to the rights, powers and
duties of the Collateral Agent, and the term "Collateral  Agent" shall mean such
successor  agent effective upon such  appointment  and approval,  and the former
Collateral  Agent's  rights,  powers and  duties as  Collateral  Agent  shall be
terminated,  without any other or further act or deed on the part of such former
Collateral  Agent or any of the parties to this  Agreement or any Secured Party.
After any retiring  Collateral  Agent's  resignation as Agent, the provisions of
this Section 7 shall inure to its benefit as to any actions  taken or omitted to
be taken by it while it was Collateral Agent under this Agreement,  the Security
Documents  and the  Guarantee.  The  resigning  Collateral  Agent will take such
actions as shall be reasonably  required to transfer and deliver the  Collateral
and Guarantee to the successor Collateral Agent.



                                    SECTION 8
                                  MISCELLANEOUS

relevant   Security   Document,   all  notices,   requests,   demands  or  other

to this subsection 8.1.

                  8.2 No Waivers. No failure on the part of the Collateral Agent
or any Secured  Party to exercise,  no course of dealing with respect to, and no
delay in exercising,  any right,  power or privilege under this  Agreement,  the
Guarantee or any Security Document shall operate as a waiver thereof,  nor shall
any single or partial exercise of any such right, power or

other right, power or privilege.

                  8.3 Amendments,  Supplements,  Waivers and Releases.  (a) With
the written consent of the Required  Secured  Parties,  the Collateral Agent and
the Borrower may, from time to time, enter into written agreements  supplemental
hereto  for the  purpose  of adding  to, or  waiving  any  provisions  of,  this
Agreement  or changing  in any manner the rights of the  Collateral  Agent,  the
Secured Parties or the Borrower  hereunder;  provided that no such  supplemental
agreement shall (i) (A) amend,  modify or waive any provision of this subsection
8.3,  (B)  amend,  modify or waive  any  provision  of  subsection  3.4,  or the

Agent and their respective successors and assigns.

                    TELIGENT CLOSES ON $800 MILLION FINANCING

Vienna, Va., July 6, 1998 - Teligent, a new integrated  communications  company,
today  announced  that it has  closed  $800  million  in senior  secured  credit
facilities  underwritten by The Chase Manhattan Bank,  Goldman Sachs and Toronto
Dominion Bank.  These  facilities  effectively  replace an existing $780 million
vendor financing commitment previously provided by Nortel (Northern Telecom).

"This   transaction   represents  a  major  milestone  for  Teligent  and  again
demonstrates  the strong support that Teligent and its business plan continue to
receive in the capital markets," said Teligent Chairman and CEO Alex J. Mandl.

Teligent  Senior Vice President and Chief  Financial  Officer  Abraham L. Morris
said,  "Teligent  has turned a vendor  financing  commitment  from Nortel into a
fully  structured  financing  that provides us with the  financial  liquidity we
believe  necessary,  while providing  sufficient  operational  flexibility on an
attractive, cost-effective basis.


"We are very  pleased  that we have  been able to  attract  a group of  premier,
market-leading  financial institutions to the syndicate,  and we look forward to
continuing  a strong  financial  partnership  with them over the coming  years,"
Morris added.

The credit  facilities  are  structured  into three  separate  tranches  and are
secured by all of the principal assets of the company.  Teligent has the ability
to borrow the funds over the next four  years,  with a final  maturity  of eight
years. The facilities  charge interest at a floating rate tied to the prevailing
LIBOR rate, and subsequently step-down when the company achieves key operational
and leverage benchmarks.

Based in Vienna, Va., Teligent, Inc. (NASDAQ:TGNT) is a full-service, integrated
communications company that will offer small and medium-sized  businesses local,
long  distance,  high-speed  data and Internet  services  over its own,  digital
wireless networks in 74 major metropolitan areas throughout the United States.
