aggregate of all expenditures by such Person for the acquisition or leasing
(pursuant to a capital lease) of fixed or capital assets or additions to

                   SECTION 2. AMOUNT AND TERMS OF COMMITMENTS

Tranche A Term Loan Lenders severally agree to make term loans ("Tranche A Term
Loans") to the Borrower on the Closing Date in a principal amount for each
Tranche A Term Loan Lender not to exceed the amount of such Lender's Tranche A
Term Loan Commitment. The Tranche A Term Loans may from time to time be
Eurodollar Loans or Base Rate Loans, as determined by the Borrower and notified
to the Administrative Agent in accordance with Sections 2.2 and 2.10.

         2.2 Procedure for Borrowing. The Borrower shall deliver to the
Administrative Agent a Borrowing Notice (which Borrowing Notice must be received
by the Administrative Agent prior to 10:00 A.M., New York City time, one
Business Day prior to the anticipated Closing Date) requesting that the Lenders
make the Loans on the Closing Date. The Loans shall initially be Base Rate
Loans. Upon receipt of such Borrowing Notice the Administrative Agent shall
promptly notify each Lender thereof. Not later than 12:00 Noon, New York City
time, on the Closing Date each Lender shall make available to the Administrative
Agent at the Funding Office an amount in immediately available funds equal to
the Loans to be made by such Lender. The Administrative Agent shall make
available to the Borrower, not later than 2:00 P.M., New York City time, on the
Closing Date, the aggregate of the amounts made available to the Administrative
Agent by the Lenders, in like funds as received by the Administrative Agent.

         2.3 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 Closing Date, 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 on the Closing Date; provided,
however, that, unless otherwise consented to by the Administrative Agent, the
aggregate Commitments of all Lehman Entities shall not, after giving effect to
each such Optional Term Loan Tranche, exceed $25,000,000. Each Optional Term
Loan Tranche shall be in a principal amount of at least $5,000,000, and all
Optional Term Loan Tranches shall not exceed $50,000,000 in the aggregate. The
Borrower shall request the establishment of an Optional Term Loan

                                                                              28

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 (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 have the same terms and conditions as are
applicable to Tranche A Term Loans hereunder, including, without limitation, the
amortization schedule, the Maturity Date, the Applicable Margin, the Commitment
Fee Rate, the procedures for borrowing and the borrowing conditions; provided,
however, that the Administrative Agent or the Optional Term Loan Lenders may
require, in connection with any Optional Term Loan Amendment relating to any
Optional Term Loan Tranche, that the Borrower or any of its Subsidiaries provide
additional collateral security for the Loans.

         (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 and the
Borrower of an Optional Term Loan Amendment relating to such Optional Term Loan
Tranche, (ii) execution and delivery by each Lender providing Optional Term Loan
Commitments under such Optional Term Loan Tranche of a Lender Addendum, with
such changes thereto as are necessary to reflect that such Lender Addendum
relates to the Optional Term Loan Amendment rather than this Agreement, pursuant
to which each such Lender becomes a party to the Optional Term Loan Amendment
relating to such Optional Term Loan Tranche, (iii) execution and delivery by the
Borrower (and, if applicable, any of its Subsidiaries) of such amendments to the
Security Documents or such other documents as the Administrative Agent
reasonably deems necessary or desirable to grant to the Collateral Agent, for
the benefit of the Secured Parties, a perfected security interest in any
Property of the Borrower or any of its Subsidiaries in which a security interest
is required to be granted in accordance with the Optional Term Loan Amendment
executed for such Tranche and (iv) 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 Lender Addendum
with respect to an Optional Term Loan Amendment executed by any Person that was
not theretofore a Lender, upon the effectiveness of such Optional Term Loan
Amendment 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.

unconditionally promises to pay to the Administrative Agent for the account of
each Lender the principal amount of the Loans of such Lender in installments

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

         (b) Each Lender shall maintain in accordance with its usual practice an
account or accounts evidencing indebtedness of the Borrower to such Lender

under this Agreement.

         (c) The Administrative Agent, on behalf of the Borrower, shall maintain

Lender, in which shall be recorded (i) the amount of each Loan made hereunder

         (d) The entries made in the Register and the accounts of each Lender
maintained pursuant to Section 2.5(b) shall, to the extent permitted by
applicable law, be prima facie evidence of the existence and amounts of the
obligations of the Borrower and the payments by 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 the 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 promptly execute and deliver to such
Lender a promissory note substantially in the form of Exhibit F (a "Note") with

of Notes shall not be a condition precedent to the occurrence of the Closing
Date or the making of the Loans on the Closing Date.

         2.6 Commitment Fees, etc. (a) The Borrower agrees to pay to the
Administrative Agent for the account of each Lender a commitment fee for the

be in an aggregate principal amount of $1,000,000 or a whole multiple thereof.

         (b) Each optional prepayment in respect of the Loans on or prior to the
third anniversary of the Closing Date shall be accompanied by a prepayment
premium equal to (i) if such prepayment is made on or prior to the first
anniversary of the Closing Date, 5% of the principal amount of such prepayment,
(ii) if such prepayment is made after the first anniversary of the Closing Date
and on or prior to the second anniversary of the Closing Date, 3% of the
principal amount of such prepayment and (iii) if such prepayment is made after

anniversary of the Closing Date, 1% of the principal amount of such prepayment.
Any prepayment of the Loans upon the refinancing thereof (whether with proceeds

be deemed to be an optional prepayment; provided, however, that the prepayment
premium applicable to any prepayment of the Loans upon the occurrence of a
Change of Control shall, notwithstanding the foregoing, be equal to 1% of the
principal amount of such prepayment.

         2.9 Mandatory Prepayments. (a) If any Indebtedness shall be incurred by

on the date of such incurrence, the Loans shall be prepaid, and/or the
Commitments shall be reduced, by an amount equal to the amount of such Net Cash

         (b) If on any date the Borrower or any of its Subsidiaries shall
receive Net Cash Proceeds from any Asset Sale or Recovery Event then, unless a
Reinvestment Notice shall be delivered in respect thereof, on the date of
receipt by the Borrower or such Subsidiary of such Net Cash Proceeds, the Loans
shall be prepaid, and/or the Commitments shall be reduced, by an amount equal to

foregoing, (i) the aggregate Net Cash Proceeds of Asset Sales and Recovery
Events (other than Recovery Events arising from satellite or launch failures)
that may be excluded from the foregoing requirement pursuant to a Reinvestment
Notice shall not exceed $5,000,000 at any one time outstanding and (ii) on each
Reinvestment Prepayment Date the Loans shall be prepaid, and/or the Commitments
shall be reduced, by an amount equal to the Reinvestment Prepayment Amount with
respect to the relevant Reinvestment Event. The provisions of this Section do
not constitute a consent to the consummation of any Disposition not permitted by
Section 6.5.

         (c) If, for any fiscal year of the Borrower commencing with the fiscal
year ending December 31, 2002, there shall be Excess Cash Flow, then, on 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), provided that no Base Rate Loan 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 Required Lenders 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 Maturity Date. Upon receipt of any such notice the
Administrative Agent shall promptly notify each Lender thereof.

         (b) Subject to Section 2.14, the Borrower may elect to continue any
Eurodollar Loan as such upon the expiration of the then current Interest Period
with respect thereto by giving irrevocable notice to the Administrative Agent,
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 may be continued as such (i)
when any Event of Default has occurred and is continuing and the Administrative
Agent has, or the Required Lenders 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 Maturity Date, 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 converted automatically to Base Rate Loans on the last day of
such then expiring Interest Period. Upon receipt of any such notice the
Administrative Agent shall promptly notify each Lender thereof.

         2.11 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 and all
selections of Interest Periods 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 $500,000 in excess thereof and (b) no more
than five Eurodollar Tranches shall be outstanding at any one time.

         2.12 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 day plus the
Applicable Margin in effect for such day.

         (b) Each Base Rate Loan shall bear interest for each day on which it is
outstanding at a rate per annum equal to the Base Rate in effect for such day
plus the Applicable Margin in effect for such day.

         (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), all outstanding Loans (whether or not overdue) (to the extent
legally permitted) shall bear interest at a rate per annum that 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 fee or other amount payable hereunder shall not be
paid when due (whether at the stated maturity, by acceleration or otherwise),
such overdue amount shall bear interest at a rate per annum equal to the rate
then applicable to Base Rate Loans 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 (after as well 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.

         2.13 Computation of Interest and Fees. (a) Interest and fees, payable
pursuant hereto shall be calculated on the basis of a 360-day year for the
actual days elapsed, except that, with respect to Base Rate Loans on which
interest 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 Lenders of each determination of a
Eurodollar Rate. Any change in the interest rate on a Loan resulting from a
change in the Base Rate 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 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 2.12(a).

         2.14 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
         Required Lenders 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 Lenders as soon as practicable thereafter. If such notice is
given (x) any Eurodollar Loans requested to be made on the first day of such
Interest Period shall be made as Base Rate Loans, (y) any Loans that were to
have been converted on the first day of such Interest Period to Eurodollar Loans
shall be continued as Base Rate Loans and (z) any outstanding Eurodollar Loans
shall be converted, on the last day of the then current Interest Period with
respect thereto, to Base Rate Loans. Until such notice has been withdrawn by the
Administrative Agent (or the Required Lenders, as the case may be, which they
agree to do as soon as circumstances allow), no further Eurodollar Loans shall
be made or continued as such, nor shall the Borrower have the right to convert
Loans to Eurodollar Loans.

         2.15 Pro Rata Treatment and Payments. (a) The 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 the respective Loan Percentages of the Lenders. Each
payment 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. Each principal prepayment of the
Loans shall be allocated among the Lenders pro rata based on the principal
amount of Loans held by such Lenders and shall be applied to the installments of
such Loans pro rata based on the remaining outstanding principal amount of such
installments. Amounts prepaid on account of the Loans may not be reborrowed.

         (b) The application of any payment of Loans (including optional and
mandatory prepayments) shall be made, first, to Base Rate Loans and, second, to
Eurodollar Loans. Each payment of the Loans shall be accompanied by accrued
interest to the date of such payment on the amount paid.

         (c) All payments (including prepayments) to be made by the Borrower
hereunder, whether on account of principal, interest, fees or otherwise, shall
be made


<PAGE>


                                                                              35


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. Any payment made by the Borrower after 12:00 Noon, New York City time, on
any Business Day shall be deemed to have been made on the next following
Business Day. 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.

         (d) 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 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
after such Borrowing Date, the Administrative Agent shall also be entitled to
recover such amount with interest thereon at the rate per annum applicable to
Base Rate Loans, on demand, from the Borrower.

         (e) Unless the Administrative Agent shall have been notified in writing
by the Borrower prior to the date of any payment due to be made by the Borrower
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 after such due
date, the Administrative Agent shall be entitled to recover, on demand, from
each Lender to which any amount 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

                                                                              36

herein shall be deemed to limit the rights of the Administrative Agent or any
Lender against the Borrower.

         2.16 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 2.17 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 that 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, upon its demand, 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 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;
provided that the Borrower shall not be required to compensate a Lender pursuant
to this paragraph for any amounts incurred more than six months prior to the
date that such Lender notifies the Borrower of such Lender's intention to claim
compensation therefor; and provided further that, if the circumstances giving
rise to such claim have a retroactive effect, then such six-month period shall
be extended to include the period of such retroactive effect.

         (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 or under 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




<PAGE>


                                                                              37


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, the Borrower shall pay to such Lender such additional amount
or amounts as will compensate such Lender or such corporation for such
reduction; provided that the Borrower shall not be required to compensate a
Lender pursuant to this paragraph for any amounts incurred more than six months
prior to the date that such Lender notifies the Borrower of such Lender's
intention to claim compensation therefor; and provided further that, if the
circumstances giving rise to such claim have a retroactive effect, then such
six-month period shall be extended to include the period of such retroactive
effect.

         (c) A certificate as to any additional amounts payable pursuant to this
Section submitted by any Lender to the Borrower (with a copy to the
Administrative Agent) 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.

         2.17 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
(i) net income taxes and franchise taxes (imposed in lieu of net income taxes)
imposed on any Agent or any Lender 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's or such Lender's having executed, delivered or performed its obligations
or received a payment under, or enforced, this Agreement or any other Loan
Document) and (ii) any branch profits taxes imposed by the United States of
America or any similar tax imposed by any other jurisdiction described in clause
(i) above. If any such non-excluded taxes, levies, imposts, duties, charges,
fees, deductions or withholdings ("Non-Excluded Taxes") or any 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 (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
withholding taxes imposed on amounts payable to such Lender at the time such
Lender becomes a party to this Agreement, except to the extent that such
Lender's assignor (if any) was entitled, at the time of assignment, to receive
additional amounts from the Borrower with respect to such Non-Excluded Taxes
pursuant to this paragraph (a).




<PAGE>


                                                                              38


         (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 Administrative Agent the required receipts or other required
documentary evidence, the Borrower shall indemnify the Agents and the Lenders
for any incremental taxes, interest or penalties (the "Assessed Amount") that
may become payable by any Agent or any Lender as a result of any such failure;
provided that in the event that any Agent or any Lender, as the case may be,
successfully contests the assessment of the Assessed Amount, such Agent or
Lender shall refund, to the extent of any refund thereof made to such Agent or
Lender, any amounts paid by the Borrower under this Section 2.17(c) in respect
of such Assessed Amount net of all out-of-pocket expenses of such Agent or
Lender attributable thereto. The Borrower, upon the request of such Agent or
Lender, agrees to repay the amount paid over to the Borrower pursuant to the
preceding sentence (plus any penalties, interest or other charges imposed by the
relevant Governmental Authority) to such Agent or Lender in the event such Agent
or Lender, as applicable, is required to repay such refund to such Governmental
Authority. The agreements in this Section 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) two copies of either U.S. Internal Revenue Service Form W-8BEN or
Form W-8ECI, 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 G and two copies of Form W-8BEN or, in either case, 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. Such forms 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). In addition, each Non-U.S. Lender shall deliver such
forms promptly upon the obsolescence, expiration or invalidity of any form
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 certificate to the Borrower (or any
other




<PAGE>


                                                                              39


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 (or Transferee) 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.

         2.18 Indemnity. The Borrower agrees to indemnify each Lender for, and
to hold each Lender harmless from, any loss (other than lost profit or margin)
or expense that such Lender may sustain or incur 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 after the Borrower has given a notice thereof in
accordance with the provisions of this Agreement or (c) the making of a
prepayment or conversion of Eurodollar Loans on a day that 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 that 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 rate
of interest for such Loans provided for herein (excluding, however, the
Applicable Margin included therein, if any) over (ii) the amount of interest (as
reasonably determined by such Lender) that 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 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.

         2.19 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, (a) the commitment of such
Lender hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and
convert Base Rate




<PAGE>


                                                                              40

Loans to Eurodollar Loans shall forthwith be canceled and (b) such Lender's
Loans then outstanding as Eurodollar Loans, if any, shall be converted
automatically to Base Rate 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 2.18.

         2.20 Change of Lending Office. Each Lender agrees that, upon the
occurrence of any event giving rise to the operation of Section 2.16, 2.17(a) or
2.19 with respect to such Lender, it will, if requested by the Borrower, use
reasonable efforts (subject to overall policy considerations of such Lender) 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 2.16, 2.17(a) or 2.19.

         2.21 Replacement of Lenders under Certain Circumstances. The Borrower
shall be permitted to replace any Lender that (a) requests reimbursement for
amounts owing pursuant to Section 2.16 or 2.17 or gives a notice of illegality
pursuant to Section 2.19 or (b) defaults in its obligation to make Loans
hereunder, with a replacement financial institution; provided that (i) such
replacement does not conflict with any Requirement of Law, (ii) no Event of
Default shall have occurred and be continuing at the time of such replacement,
(iii) prior to any such replacement, such Lender shall have taken no action
under Section 2.20 so as to eliminate the continued need for payment of amounts
owing pursuant to Section 2.16 or 2.17 or to eliminate the illegality referred
to in such notice of illegality given pursuant to Section 2.19, (iv) the
replacement financial institution shall purchase, at par, all Loans and other
amounts owing to such replaced Lender on or prior to the date of replacement,
(v) the Borrower shall be liable to such replaced Lender under Section 2.18 (as
though Section 2.18 were applicable) if any Eurodollar Loan owing to such
replaced Lender shall be purchased other than on the last day of the Interest
Period relating thereto, (vi) the replacement financial institution, if not
already a Lender, shall be reasonably satisfactory to the Administrative Agent,
(vii) the replaced Lender shall be obligated to make such replacement in
accordance with the provisions of Section 9.6 (provided that the Borrower shall
be obligated to pay the registration and processing fee referred to therein),
(viii) the Borrower shall pay all additional amounts (if any) required pursuant
to Section 2.16 or 2.17, as the case may be, in respect of any period prior to
the date on which such replacement shall be consummated, and (ix) any such
replacement shall not be deemed to be a waiver of any rights that the Borrower,
the Administrative Agent or any other Lender shall have against the replaced
Lender.

                    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. (a) The audited consolidated balance
sheets of the Borrower as at December 31, 1999 and December 31, 1998, and the
related consolidated statements of income and of cash flows for the fiscal years
ended on such dates, reported on by and accompanied by an unqualified report
from Arthur Andersen LLP, present fairly in all material respects 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
respective fiscal years then ended. The unaudited consolidated balance sheet of
the Borrower as at March 31, 2000, and the related unaudited consolidated
statements of income and cash flows for the three-month period ended on such
date, present fairly in all material respects 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 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, that are not reflected in the
most recent financial statements referred to in this paragraph or that have not
been disclosed to the Lenders. During the period from December 31, 1999 to and
including the date hereof there has been no Disposition by the Borrower or any
of its Subsidiaries of any material part of its business or Property.

                  3.2 No Change. Since December 31, 1999 there has been no
development or event that 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 (or other entity) 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 (or other entity) and in good standing under the laws of
each jurisdiction where its ownership, lease or operation of Property or the

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 (or other entity) 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 (or other entity) 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 the
execution, delivery, performance, validity or enforceability of this Agreement
or any of the other Loan Documents by or against the Loan Parties, except (i)
consents, authorizations, filings and notices described in Schedule 3.4, which
consents, authorizations, filings and notices have been obtained or made and are
in full force and effect and (ii) the filings referred to in Section 3.19. Each
Loan Document has been duly executed and delivered on behalf of each Loan Party
that 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 that 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 the Security Documents).
No Requirement of Law or Contractual Obligation applicable to the Borrower or
any of its Subsidiaries could 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) that could 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 that 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
Subsidiaries has title in fee simple to, or a valid leasehold interest in, all
its real property,




<PAGE>



                                                                              43



and good title to, or a valid leasehold interest in, all its other Property, 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
Subsidiaries owns, or is licensed to use, all Intellectual Property necessary
for the conduct of its business as currently conducted. 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, nor does the Borrower know of any valid basis for any such claim. The
use of Intellectual Property by the Borrower and its Subsidiaries does not
infringe on the rights of any Person in any material respect.

                  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 that 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 material taxes, fees or other charges imposed on it or
any of its Property by any Governmental Authority (other than any 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);
and 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
any 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).

                  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 that 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 Labor Matters. There are no strikes or other labor
disputes against the Borrower or any of its Subsidiaries pending or, to the
knowledge of the Borrower, threatened that (individually or in the aggregate)
could reasonably be expected to have a Material Adverse Effect. Hours worked by
and payment made to employees of the Borrower and its Subsidiaries have not been
in violation of the Fair Labor Standards Act or any other applicable Requirement
of Law dealing with such matters that (individually or in the aggregate) could
reasonably be expected to have a Material Adverse Effect. All payments due from
the Borrower or any of its Subsidiaries on account of employee health and
welfare insurance that (individually or in the aggregate) could reasonably be
expected to have a Material Adverse Effect if not paid have been paid or accrued
as a liability on the books of the Borrower or the relevant Subsidiary.

                                                                              44

                  3.13 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. No termination of a Single Employer Plan has occurred,
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. Neither the Borrower nor any
Commonly Controlled Entity has had a complete or partial withdrawal from any
Multiemployer Plan that 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. No such Multiemployer
Plan is in Reorganization or Insolvent.

                  3.14 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.

                  3.15 Subsidiaries. (a) The Subsidiaries listed on Schedule
3.15 constitute all the Subsidiaries of the Borrower at the date hereof.
Schedule 3.15, as such schedule may be supplemented from time to time between
the date hereof and the Closing Date in a written notice from the Borrower to
the Administrative Agent, sets forth as of the Closing Date the name and
jurisdiction of incorporation of each Subsidiary and, as to each Subsidiary, the
percentage of each class of Capital Stock owned by each Loan Party.

                  (b) There are no outstanding subscriptions, options, warrants,
calls, rights or other agreements or commitments (other than stock options
granted to employees or directors and directors' qualifying shares) of any
nature relating to any Capital Stock of the Borrower or any Subsidiary, except
as disclosed on Schedule 3.15.

                  3.16 Use of Proceeds. The proceeds of the Loans shall be used
to finance capital expenditures and general working capital needs and for the
general corporate purposes of the Borrower and its Subsidiaries.

                  3.17 Environmental Matters. Other than exceptions to any of
the following that could not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect:





<PAGE>


                                                                              45

         are, and within the period of all applicable statutes of limitation

         be timely renewed and complied with, without material expense; any
         additional Environmental Permits that may be required of any of them
         will be timely obtained and complied with, without material expense;
         and compliance with any Environmental Law that is or is expected to
         become applicable to any of them will be timely attained and
         maintained, without material expense.

                  (b) Materials of Environmental Concern are not present at, on,
         under, in, or about any real property now or formerly owned, leased or
         operated by the Borrower or any of its Subsidiaries, or at any other
         location (including, without limitation, any location to which
         Materials of Environmental Concern have been sent for re-use or
         recycling or for treatment, storage, or disposal) which could
         reasonably be expected to (i) give rise to liability of the Borrower or
         any of its Subsidiaries under any applicable Environmental Law or
         otherwise result in costs to the Borrower or any of its Subsidiaries,
         or (ii) interfere with the Borrower's or any of its Subsidiaries'
         continued operations, or (iii) impair the fair saleable value of any
         real property owned or leased by the Borrower or any of its
         Subsidiaries.

                  (c) There is no judicial, administrative, or arbitral
         proceeding (including any notice of violation or alleged violation)
         under or relating to any Environmental Law to which the Borrower or any
         of its Subsidiaries is, or to the knowledge of the Borrower or any of
         its Subsidiaries will be, named as a party that is pending or, to the
         knowledge of the Borrower or any of its Subsidiaries, threatened.

                  (d) Neither the Borrower nor any of its Subsidiaries has
         received any written request for information, or been notified that it
         is a potentially responsible party under or relating to the federal
         Comprehensive Environmental Response, Compensation, and Liability Act
         or any similar Environmental Law, or with respect to any Materials of
         Environmental Concern.

                  (e) Neither the Borrower nor any of its Subsidiaries has

         forum for dispute resolution, relating to compliance with or liability
         under any Environmental Law.

                  (f) Neither the Borrower nor any of its Subsidiaries has
         assumed or retained, by contract or operation of law, any liabilities
         of any kind, fixed or




<PAGE>


                                                                              46


         contingent, known or unknown, under any Environmental Law or with
         respect to any Material of Environmental Concern.

                  3.18 Accuracy of Information, etc. No statement or information
contained in this Agreement, any other Loan Document, the Confidential
Information Memorandum (once prepared) or any other document, certificate or
statement furnished to the Administrative Agent or the Lenders or any of them,
by or on behalf of any Loan Party for use in connection with the transactions
contemplated by this Agreement or the other Loan Documents, when taken as a
whole, contained as of the date such statement, information, document or
certificate was so furnished, 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 misleading. 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 (once prepared) or in any other documents, certificates and
statements furnished to the Agents and the Lenders for use in connection with
the transactions contemplated hereby and by the other Loan Documents.

                  3.19 Security Documents. (a) The Collateral Agreement is
effective to create in favor of the Collateral Agent, for the benefit of the
Secured Parties, a legal, valid and enforceable security interest in the
Collateral described therein and proceeds thereof. When financing statements in
appropriate form are filed in the offices specified on Schedule 3.19(a)-1, the
Collateral Agreement shall 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 Collateral Agreement), in each case prior and superior in right to any
other Person (except Liens permitted by Section 6.3). Schedule 3.19(a)-2 lists
each UCC Financing Statement that (i) names any Loan Party as debtor and (ii)
will remain on file after the Closing Date. Schedule 3.19(a)-3 lists each UCC
Financing Statement that (i) names any Loan Party as debtor and (ii) will be
terminated on or prior to the Closing Date; and on or prior to the Closing Date,
the Borrower will have delivered to the Administrative Agent, or caused to be
filed, duly completed UCC termination statements, signed by the relevant secured
party, in respect of each UCC Financing Statement listed in Schedule 3.19(a)-3.

                  (b) The Pledge Agreement is effective to create in favor of

title and interest of the Loan Parties in such Pledged Collateral and the

                  3.20 Solvency. Each Loan Party is, and after giving effect to
the incurrence of all Indebtedness and obligations being incurred in connection
herewith will be and will continue to be, Solvent.

                  3.21 Licenses; Permits; etc. Schedule 3.21 accurately and
completely lists as of the date hereof all material authorizations, licenses and
permits of any public or governmental regulatory body granted or assigned to the
Borrower or any of its Subsidiaries, and except as set forth on Schedule 3.21,
the same constitute the only material authorizations, licenses and permits of
any public or governmental regulatory body which are required or necessary for
the conduct of the respective businesses of the Borrower and its Subsidiaries as
now conducted or proposed to be conducted (such authorizations, licenses and
permits, together with any extensions or renewals thereof, being herein
sometimes referred to collectively as the "Licenses"). Except as set forth on
Schedule 3.21, all of such Licenses listed in Schedule 3.21 are issued in the
name of, or are validly assigned to, the Borrower or the License Subsidiary and
are validly issued and in full force and effect and have not been revoked,
suspended, canceled, or modified in any adverse way, and the Borrower or the
License Subsidiary, as applicable, has (a) fulfilled and performed in all
material respects all of its obligations with respect thereto and (b) full power

                  3.22 FCC Compliance, etc. (a) The Borrower and each of its
Subsidiaries are (and, after giving effect to the transactions contemplated by
this Agreement, each will be) in compliance with all rules, regulations and
administrative orders of the FCC applicable to the Borrower or any of its
Subsidiaries or the operation of its Properties, except where the failure to be
in such compliance could not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect.

                  (b) 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 of any other proceedings of or before the FCC, which
could reasonably be expected to have a Material Adverse Effect; and no
proceedings are pending or, to the knowledge of the Borrower, threatened, to
revoke or limit any FCC License, except, in each case, those which do not and
could not reasonably be expected to have a Material Adverse Effect.

                  (c) The Borrower has no knowledge of the occurrence of any
event which (i) could result 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 FCC License in any respect that could

                                                                              48


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 the License Subsidiary under any FCC License in any respect that
could reasonably be expected to have a Material Adverse Effect.

                  (d) Each of the Borrower and the License Subsidiary 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 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.

                  4.1 Conditions to Loans. The agreement of each Lender to make

         from the sale of the Borrower's common stock and common stock
         equivalents (it being understood that (x) the sale of convertible debt

                   (l) Any Change of Control shall occur;


then, and in any such event, (A) if such event is an Event of Default specified
in clause (i) or (ii) of paragraph (f) above with respect to the Borrower,
automatically the Commitments shall immediately terminate and the Loans
hereunder (with accrued interest thereon) and all other amounts owing under this
Agreement and the other Loan Documents shall immediately become due and payable,
and (B) if such event is any other Event of Default, either or both of the
following actions may be taken: (i) with the consent of the Required Lenders,
the Administrative Agent may, or upon the request of the Required Lenders, the
Administrative Agent shall, by notice to the Borrower declare the Commitments to
be terminated forthwith, whereupon the Commitments shall immediately terminate;
and (ii) with the consent of the Required Lenders, the Administrative Agent may,
or upon the request of the Required Lenders, the Administrative Agent shall, by
notice to the Borrower, declare the Loans hereunder (with accrued interest
thereon) and all other amounts owing under this Agreement and the other Loan
Documents to be due and payable forthwith, whereupon the same shall immediately
become due and payable.

                              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 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 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,







<PAGE>



                                                                              71


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 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 or any other Loan Document
(except to the extent that any of the foregoing are found by a final and
nonappealable decision of a court of competent jurisdiction to have 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 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 such Agent. The Agents may deem and treat the payee of
any Note as the owner thereof for all purposes unless such Note shall have been
transferred in accordance with Section 9.6 and all actions required by such
Section in connection with such transfer shall have been taken. 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 or any other instructing group of Lenders specified by this
Agreement) as it deems appropriate or it shall first be indemnified to its
satisfaction by the Lenders against any and all liability and expense that 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 or any other instructing group of Lenders specified by this
Agreement), and such request and any







<PAGE>



                                                                              72


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 shall have 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 shall receive 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 or any other instructing group of Lenders specified by
this Agreement); 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 any of the Agents nor any of their
respective officers, directors, employees, agents, attorneys-in-fact 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 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 that 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 Loan







<PAGE>



                                                                              73


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 Loan Percentages immediately prior to such
date), for, and to save each Agent harmless from and against, any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind whatsoever that 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 that 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 were 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 10 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 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. The Syndication Agent
may, at any time, by notice to the Lenders and the Administrative Agent, resign
as Syndication Agent hereunder, whereupon the duties, rights, obligations and
responsibilities of the Syndication Agent hereunder shall automatically be
assumed by, and inure to the benefit of, the Administrative Agent, without any
further act by the Syndication Agent, the Administrative Agent or any Lender.
After any retiring Agent's resignation as

                                                                              74


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 and Guarantees. The
Administrative Agent is hereby irrevocably authorized by each of the Lenders (a)
to effect any release of Guarantees issued by any Subsidiary upon the
Disposition, in a transaction permitted by this Agreement or which has been
consented to in accordance with Section 9.1, of such Subsidiary or of
substantially all of its assets, (b) to direct the Collateral Agent to effect
any release of Liens 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 and (c)
to amend the Intercreditor Agreement to permit obligations in respect of
Additional Senior Debt permitted by this Agreement in an aggregate principal
amount of up to $500,000,000 to be secured equally and ratably by the Capital
Stock of the License Subsidiary.

                   8.11 The Arranger; the Syndication Agent. Neither the
Arranger nor the Syndication 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 or 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 9.1. The Required Lenders and each Loan Party party to the relevant Loan
Document may, or (with the written consent of the Required Lenders) the Agents
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 (including amendments and restatements hereof or
thereof) for the purpose of adding 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 may be specified in the instrument of waiver, 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 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;






<PAGE>



                                                                              75


                   (ii) amend, modify or waive any provision of this Section or
         reduce any percentage specified in the definition of Required 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, release all or substantially all of the Collateral or
         release all or substantially all of the Guarantees, in each case
         without the consent of all Lenders;

                   (iii) amend, modify or waive any provision of Section 8
         without the consent of any Agent directly affected thereby; or

                   (iv) amend, modify or waive any provision of Section 2.15
         without the consent of each Lender directly affected thereby;

provided, further, that the Pledge Agreement and the Intercreditor Agreement may
be amended only in accordance with the applicable provisions 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
Agents and all future holders of the Loans. In the case of any waiver, the Loan
Parties, the Lenders and the Agents 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.

                   Notwithstanding the foregoing and notwithstanding anything to
the contrary in Section 2.15, in the event that the Borrower wishes to extend
the final maturity date of any Loan or the expiry date of any Lender's
Commitment, and (A) one Lender holding aggregate outstanding Loans and unused
Commitments representing not more than 15% of the aggregate outstanding Loans
and unused Commitments of all Lenders does not consent to such extension or (B)
Lenders holding aggregate outstanding Loans and unused Commitments representing
not more than 10% of the aggregate outstanding Loans and unused Commitments of
all Lenders do not consent to such extension, the Borrower may prepay in full
the outstanding Loans of such Lender (or Lenders, as applicable) and terminate
the Commitments of such Lender (or Lenders, as applicable), in each case on a
non-pro rata basis, and, upon such prepayment, the remaining Loans and
Commitments shall remain outstanding and this Agreement, as modified by such
amendment, shall continue in full force and effect.

                   For the avoidance of doubt, this Agreement and any other Loan
Document may be amended (or amended and restated) with the written consent of
the Required Lenders, the Administrative Agent and each Loan Party to each
relevant Loan Document (x) to add one or more additional credit facilities to
this Agreement and to

permit the extensions of credit from time to time outstanding thereunder and the
accrued interest and fees in respect thereof to share ratably in the benefits of
this Agreement and the other Loan Documents with the Loans and the accrued
interest and fees in respect thereof and (y) to include appropriately the
Lenders holding such credit facilities in any determination of the Required
Lenders.

provided that any notice, request or demand to or upon the any Agent or any
Lender shall not be effective until received.

                   9.3 No Waiver; Cumulative Remedies. No failure to exercise
and no delay in exercising, on the part of any Agent or any Lender, any right,
remedy, power or privilege hereunder or under the other Loan Documents shall
operate as a waiver thereof; nor shall any single or partial exercise of any
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 herein, in the other Loan Documents and in

                   9.5 Payment of Expenses. The Borrower agrees (a) to pay or
reimburse the Agents for all their reasonable out-of-pocket costs and expenses
incurred in connection with the syndication of the Loans and the Commitments
(other than fees payable to syndicate members) and the development, preparation
and execution of, and any amendment, supplement or modification to, this
Agreement and the other Loan Documents and any other documents prepared in
connection herewith or therewith, and the consummation of the transactions
contemplated hereby and thereby, including, without limitation, the reasonable
fees and disbursements and other charges of counsel to the Administrative Agent
and the use of Intra-Links, (b) to pay or reimburse each Lender and the Agents
for all their costs and expenses incurred in connection with the enforcement or
preservation of any rights under this Agreement, the other Loan Documents and
any other documents prepared in connection herewith or therewith, including,
without limitation, the fees and disbursements of counsel (including the

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 or reimburse

officers, directors, trustees, employees, advisors, agents and controlling
persons (each, an "Indemnitee") for, and hold each Indemnitee harmless from and

                                                                              78


against, any and all other liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, 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 and the fees and
disbursements and other charges of legal counsel in connection with claims,
actions or proceedings by any Indemnitee against the Borrower hereunder (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 are found by a court of competent jurisdiction to have 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, under or related to Environmental Laws, that any of
them might have by statute or otherwise against any Indemnitee. All amounts due
under this Section shall be payable not later than 30 days after written demand
therefor. Statements for amounts payable by the Borrower pursuant to this
Section shall be submitted to Michael Haynes, Treasurer, (Telephone No. (212)
584-5152) (Fax No. (212) 584-5252), at the address of the Borrower set forth in
Section 9.2, or to such other Person or address as may be hereafter designated
by the Borrower in a notice to the Administrative Agent. 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.
(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 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

                                                                              79


such participation have any right to approve 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 require the consent of all Lenders pursuant to Section 9.1. 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 such Participant were a Lender hereunder. The Borrower also agrees
that each Participant shall be entitled to the benefits of Sections 2.16, 2.17
and 2.18 with respect to its participation in the Commitments and the Loans
outstanding from time to time as if such Participant were a Lender; provided
that, in the case of Section 2.17, 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 and upon written notice to the Administrative Agent, at any time
and from time to time assign to any Lender or any affiliate or Control
Investment Affiliate thereof or, with the consent of the Borrower and the Agents
(which, in each case, shall not be unreasonably withheld or delayed) (provided
that no such consent need be obtained by any Lehman Entity until the first time
the Lehman Entities hold aggregate outstanding Loans and unused Commitments of
no more than $20,000,000), 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 D, executed by such Assignee and such Assignor (and, where the consent
of the Borrower or the Agents 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) 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. 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 Commitments and/or Loans as set forth therein; provided, that no assignee
(including an assignee that is already a Lender hereunder at the time of the
assignment) shall be entitled to receive any greater amount pursuant to Section
2.17 than that to which the assignor would have been entitled to receive had no
such

                                                                              80


assignment occurred, 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, except as to Sections 2.16, 2.17 and 9.5 in
respect of the period prior to such effective date). Notwithstanding any
provision of this Section, the consent of the Borrower shall not be required for
any assignment that occurs at any time when any Event of Default shall have
occurred and be continuing.

                   (d) The Administrative Agent shall, on behalf of the
Borrower, 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 Commitment 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, each 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 "canceled". The Register shall be available for
inspection by the Borrower or any Lender (with respect to any entry relating to
such Lender's Loans) 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 (except that no such registration and processing fee shall be payable (y)
in connection with an assignment by or to any Lehman Entity or (z) in the case
of an Assignee which is already a Lender or is an affiliate of a Lender or a
Person under common management with a Lender), 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 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 Note
of the assigning Lender) a new Note to the order of such Assignee in an amount
equal to the Loans acquired by it pursuant to such Assignment and Acceptance
and, if the Assignor has retained a Loan, upon request, a new Note to the order
of the Assignor in an amount equal to the Loans 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 in Loans and Notes, including,
without limitation, any pledge or assignment by a Lender of any Loan or Note to
any Federal Reserve Bank in accordance with applicable law, provided that any
assignment pursuant to an exercise of remedies under any such security interest
shall comply with Sections 9.6(c) through (e).

                   9.7 Adjustments; Set-off. (a) Except to the extent that this
Agreement provides for payments to be allocated to a particular Lender, 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. 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 or of a Lender

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 that 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 entire agreement of the Borrower, the Agents, the Arranger and the
Lenders with respect to the subject matter hereof and thereof, and there are no
promises, undertakings, representations or warranties by the Arranger, any Agent
or any Lender relative to subject matter hereof not expressly set forth or
referred to herein or in the other Loan Documents.

                   9.11 GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT SHALL BE GOVERNED BY, AND

                   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;

         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

                   (d) agrees that nothing herein shall affect the right to

                   (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 and any damages arising from the use by
         unauthorized persons of materials sent through electronic,
         telecommunications or other information transmission systems that are
         intercepted by such persons.

                   9.13 Acknowledgments. 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;

                   (b) neither the Arranger, any 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 the Arranger, the Agents and the 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 Arranger, the Agents and the Lenders or

agrees to keep confidential all non-public information provided to it by any

in connection with the exercise of any remedy hereunder or under any other Loan
Document.

                   9.15 Release of Collateral and Guarantee Obligations. (a)
Notwithstanding anything to the contrary contained herein or in any other Loan
Document, upon request of the Borrower in connection with any Disposition of
Property permitted by the Loan Documents, the Administrative Agent shall
(without notice to, or vote or consent of, any Lender, or any affiliate of any
Lender that is a party to any Specified Hedge Agreement) take such actions as
shall be required to release its security interest in any Collateral being
Disposed of in such Disposition, and to release any guarantee obligations under
any Loan Document of any Person being Disposed of in such Disposition, to the
extent necessary to permit consummation of such Disposition in accordance with
the Loan Documents.

                   (b) Notwithstanding anything to the contrary contained herein
or any other Loan Document, when all Obligations (other than obligations in
respect of any Specified Hedge Agreement) have been paid in full, all
Commitments have terminated or expired, upon request of the Borrower, the
Administrative Agent shall (without notice to, or vote or consent of, any
Lender, or any affiliate of any Lender that is a party to any Specified Hedge
Agreement) take such actions as shall be required to release its security
interest in all Collateral, and to release all guarantee obligations under any
Loan Document, whether or not on the date of such release there may be
outstanding Obligations in respect of Specified Hedge Agreements. Any such
release of guarantee obligations shall be deemed subject to the provision that
such guarantee obligations shall be reinstated if after such release any portion
of any payment in respect of the Obligations guaranteed thereby shall be
rescinded or must otherwise be restored or returned 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 payment had not been made.

                   9.16 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 Change with the desired result that the
criteria for evaluating the Borrower's financial condition shall be the same
after such Accounting Change as if such Accounting Change 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 Change had not occurred. "Accounting Change"
refers to any change in accounting principles required by the promulgation of
any rule, regulation, pronouncement or opinion by the Financial

                  (c) 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.

                  4.6 Notices. The Borrower will advise the Collateral Agent and
the Representatives promptly, in reasonable detail, of:

                  (a) any Lien on any of the Collateral which would adversely
affect the ability of the Collateral Agent to exercise any of its remedies
hereunder; and

                  (b) the occurrence of any other event which could reasonably
be expected to have a material adverse effect on the aggregate value of the
Collateral or on the security interests created hereby.

                  4.7 Satellite Contract. The Borrower will perform and comply
in all material respects with all its obligations under the Satellite Contract.

                         SECTION 5. REMEDIAL PROVISIONS

                  5.1 Communications with Obligors; Borrower Remains Liable. (a)
Each of the Collateral Agent and the Administrative Agent, in its own name or in
the name of others, may at any time communicate with the parties to the
Satellite Contract to verify with them to the satisfaction of the Collateral
Agent or the Administrative Agent, as the case may be, the existence, amount and
terms of such Contract.

                  (b) Upon the request of the Collateral Agent at any time after
the occurrence and during the continuance of an Event of Default, the Borrower
shall notify parties to the Satellite Contract that the Satellite Contract has
been assigned to the Collateral Agent for the ratable benefit of the Secured
Parties and that any payments in respect thereof shall be made directly to the
Collateral Agent.

                  (c) Anything herein to the contrary notwithstanding, the
Borrower shall remain liable under the Satellite Contract 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 the Satellite Contract 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 the
Borrower under or pursuant to the Satellite Contract, 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.

                                                                              13


                  5.2 Proceeds to be Turned Over To Collateral Agent. If an
Event of Default shall occur and be continuing, all Proceeds received by the
Borrower consisting of cash, checks and other near-cash items shall be held by
the Borrower in trust for the Collateral Agent and the Secured Parties,
segregated from other funds of the Borrower, and shall, forthwith upon receipt
by the Borrower, be turned over to the Collateral Agent in the exact form
received by the Borrower (duly indorsed by the Borrower 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 the Borrower in trust for the Collateral Agent and 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 5.3.

                  5.3 Application of Proceeds. At such intervals as may be
agreed upon by the Borrower and the Collateral Agent, or, if an Event of Default
shall have occurred and be continuing, at any time at the Collateral Agent's
election, the Collateral Agent may apply all or any part of Proceeds
constituting Collateral (after the payment of any amounts payable to the
Collateral Agent pursuant to Section 7.4(a)), whether or not held in any
Collateral Account, for the ratable benefit of the Secured Parties in payment of
the Obligations in the manner set forth in the Intercreditor Agreement. Any
balance of such proceeds remaining after the Obligations shall have been paid in
full and the Commitments shall have been terminated shall be paid over to the
Borrower or to whomsoever may be lawfully entitled to receive the same.

                  5.4 Code and Other Remedies. If an Event of Default shall
occur and be continuing, 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, 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 the Borrower or any other
Person (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
the Borrower, which right or equity is hereby waived and released. The Borrower
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 the Borrower's premises or elsewhere.
The Collateral Agent shall apply the

net proceeds of any action taken by it pursuant to this Section 5.4, 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 Collateral Agent and
the Secured Parties hereunder, including, without limitation, reasonable
attorneys' fees and disbursements, to the ratable payment in whole or in part of
the Obligations, in the manner set forth in the 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 the Borrower. To the extent permitted by applicable law,
the Borrower waives all claims, damages and demands 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.

                  5.5 Waiver; Deficiency. The Borrower waives and agrees not to
assert any rights or privileges which it may acquire under Section 9-112 of the
New York UCC. The Borrower shall remain liable for any deficiency if the
proceeds of any sale or other disposition of the Collateral are insufficient to
pay its Obligations and the fees and disbursements of any attorneys employed by
the Collateral Agent or any Secured Party to collect such deficiency.

                         SECTION 6. THE COLLATERAL AGENT

                  6.1 Collateral Agent's Appointment as Attorney-in-Fact, etc.
(a) The Borrower 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 the Borrower and in the name of the Borrower 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, the
Borrower hereby gives the Collateral Agent the power and right, on behalf of the
Borrower, without notice to or assent by the Borrower, to do any or all of the
following:

                  (1) in the name of the Borrower 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
          the Satellite Contract 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 the
          Satellite Contract or with respect to any other Collateral whenever
          payable;







<PAGE>


                                                                              15


                  (2) 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;

                  (3) execute, in connection with any sale provided for in
          Section 5.4, any indorsements, assignments or other instruments of
          conveyance or transfer with respect to the Collateral; and

                  (4) (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
          the Borrower 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; and (7) 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 the Borrower'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
          Collateral Agent's and the Secured Parties' security interests therein
          and to effect the intent of this Agreement, all as fully and
          effectively as the Borrower might do.

                  Anything in this Section 6.1(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 6.1(a) unless an
Event of Default shall have occurred and be continuing.

                  (b) If the Borrower 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 6.1, 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 Base Rate Loans under the Term Loan
Agreement, from the date of payment by the Collateral Agent to the date
reimbursed by the Borrower, shall be payable by the Borrower to the Collateral
Agent on demand.

                                                                              16


                  (d) The Borrower 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.

                  6.2 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 the Borrower 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 Collateral Agent's and
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 the Borrower for any act or failure to act hereunder, except for
their own gross negligence or willful misconduct.

                  6.3 Execution of Financing Statements. Pursuant to Section
9-402 of the New York UCC and any other applicable law, the Borrower 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 the Borrower 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. 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.

                  6.4 Authority of Collateral Agent. The Borrower 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, 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 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 Borrower, 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 the Borrower shall be
under no obligation, or entitlement, to make any inquiry respecting such
authority.

                          SECTION 7.  MISCELLANEOUS

                  7.1 Amendments in Writing. None of the terms or provisions of
this Agreement may be waived, amended, supplemented or otherwise modified except
by a written instrument executed by each of the Borrower and the Collateral
Agent, provided that any provision of this Agreement imposing obligations on the
Borrower may be waived by the Collateral Agent in a written instrument executed

                  7.3 No Waiver by Course of Conduct; Cumulative Remedies.
Neither the Collateral Agent nor any Secured Party shall by any act (except by a
written instrument pursuant to Section 7.1), delay, indulgence, omission or
otherwise be deemed to have waived any right or remedy hereunder or to have
acquiesced in any Default or Event of Default. 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.

                  7.4 Enforcement Expenses; Indemnification. (a) The Borrower
agrees to pay, or reimburse the Collateral Agent for, all its costs and expenses
incurred in enforcing or preserving any rights under this Agreement, 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 Borrower agrees to pay, and to save the Collateral
Agent and the Secured Parties harmless from, any and all liabilities with
respect to, or resulting from any delay in paying, any and all stamp, excise,
sales or other taxes which may be payable or determined to be payable with
respect to any of the Collateral or in connection with any of the transactions
contemplated by this Agreement.

                  (c) The Borrower agrees to pay, and to save the Collateral
Agent and the Secured Parties harmless from and against, any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind whatsoever that may at any time
(including, without limitation, at any time following the payment of the
Obligations) be imposed on, incurred by or asserted against the Collateral Agent
or the Secured Parties in any way relating to or arising out of this Agreement
or the transactions contemplated hereby or any action taken or omitted by the
Collateral Agent or the Secured Parties under or in connection with any of the
foregoing; provided that the Borrower shall not be liable for the payment of any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements that are found by a court of
competent jurisdiction to have resulted from the gross negligence or willful
misconduct of the Collateral Agent or such Secured Party, as applicable.

                                                                              19


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

                  7.5 Successors and Assigns. This Agreement shall be binding
upon the successors and assigns of the Borrower and shall inure to the benefit
of the Collateral Agent and the Secured Parties and their successors and
assigns; provided that the Borrower may not assign, transfer or delegate any of
its rights or obligations under this Agreement without the prior written consent
of the Collateral Agent.

                  7.6 Set-Off. The Borrower hereby irrevocably authorizes the
Collateral Agent at any time and from time to time while an Event of Default
shall have occurred and be continuing, without notice to the Borrower, any such
notice being expressly waived by the Borrower, 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 to or
for the credit or the account of the Borrower, or any part thereof in such
amounts as the Collateral Agent may elect, against and on account of the
obligations and liabilities of the Borrower to the Collateral Agent hereunder
and claims of every nature and description of the Collateral Agent or the
Secured Parties against the Borrower, in any currency, whether arising
hereunder, under any Secured Debt Document or otherwise, as the Collateral Agent
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 shall notify the Borrower promptly
of any such set-off and the application made by the Collateral Agent 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
under this Section are in addition to other rights and remedies (including,
without limitation, other rights of set-off) which the Collateral Agent may
have.

                  7.7 Counterparts. This Agreement may be executed by one or
more of the parties to this Agreement on any number of separate counterparts

Inc., a Delaware corporation (the "Borrower"), and Satellite CD Radio, Inc., a
Delaware corporation (the "Subsidiary" and, together with the Borrower, the
"Principal Parties"), in connection with the Term Loan Agreement (the "Term Loan
Agreement") dated as of June 1, 2000 among the Borrower, the financial
institutions parties to the Term Loan Agreement on the date hereof (the
"Lenders"), and Lehman Commercial Paper Inc., as administrative agent (the
"Agent"). This opinion is being furnished to you at the request of the Borrower
as provided by Section 4.1(k)(i) of the Term Loan Agreement. Capitalized terms
used and not otherwise defined have the respective meanings given those terms in
the Term Loan Agreement.

                  In connection with this opinion, we have examined originals,
or copies certified or otherwise identified to our satisfaction, of the
following documents, each dated as of the date indicated below (collectively,
the "Documents"):







<PAGE>



1.    the Term Loan Agreement dated as of June 1, 2000;

2.    the Notes dated as of the date hereof;
      the Pledge Agreement dated as of the date hereof; and the Collateral
      Agreement dated as of the date hereof.

         In addition, we have examined those certificates, agreements and
documents that we deemed relevant and necessary as a basis for our opinion. We
have also relied upon the factual matters contained in the representations and
warranties of the Principal Parties made in the Documents and upon certificates
of public officials and the Principal Parties.

         In our examination of the documents referred to above, we have assumed,
without independent investigation, the genuineness of all signatures, the legal
capacity of all individuals who have executed any of the documents reviewed by
us, the authenticity of all documents submitted to us as originals, the
conformity to the originals of all documents submitted to us as certified,
photostatic, reproduced or conformed copies of valid existing agreements or
other documents, the authenticity of the latter documents and that the
statements regarding matters of fact in the certificates, records, agreements,
instruments and documents that we have examined are accurate and complete. We
have also assumed, without independent investigation, the enforceability of the
Documents against each party other than the Principal Parties.

         In addition, in the case of each Principal Party, we have assumed,
without independent investigation, that (i) the Principal Party is validly
existing and in good standing under the laws of its jurisdiction of
organization, (ii) the Principal Party has all necessary corporate power and
authority to execute, deliver and perform its obligations under each Document to
which it is a party, (iii) the execution, delivery and performance of each
Document have been duly authorized by all necessary corporate







<PAGE>


action and do not violate its charter or other organizational documents or the
laws of its jurisdiction of organization and (iv) each Document has been duly
executed and delivered by it.

         Based upon the foregoing, and subject to the assumptions, exceptions
and qualifications stated below, we are of the opinion that:

         Each Document to which each Principal Party is a party constitutes the
legal, valid and binding obligation of such Principal Party, enforceable against
such Principal Party in accordance with its terms.

         The execution and delivery by each Principal Party of each of the
Documents to which it is a party and the performance by the Principal Party of
its obligations under the Documents to which it is a party do not violate or
result in a breach of or default under any Covered Law (as defined below)
(including Regulations U or X of the Board of Governors of the Federal Reserve
System of the United States), the Senior Discount Note Indenture as in effect on
the date hereof or the Senior Note Indenture as in effect on the date hereof.

         Except for filings which are necessary to perfect the security
interests granted under the Documents and any other filings, authorizations or
approvals as are specifically provided for in the Documents, no authorizations
or approvals of, and no filings with, any governmental or regulatory authority
or agency are necessary under any Covered Law for the execution, delivery or
performance by any Principal Party of the Documents to which it is a party, the
borrowings by the Borrower in accordance with the terms of the Term Loan
Agreement or the granting of any security interests under the Documents.







<PAGE>


         None of the Principal Parties is required to be registered as an
"investment company" within the meaning of the Investment Company Act of 1940,
as amended.

         After giving effect to the making of the Loans on the date of this
letter, and assuming that (i) the Collateral Agent has, at the date of this
letter, possession of the certificates representing the Pledged Shares (as
defined in the Pledge Agreement) in the State of New York, together with related
stock powers which have been duly executed in blank by the Borrower, and
maintains continuous possession of those Pledged Shares and stock powers in the
State of New York, and (ii) on the date of this letter, the Lenders, the Agent,
the Holders, the New Note Trustee, the Old Note Trustee (as such terms are
defined in the Pledge Agreement) and the Collateral Agent (the "Secured
Parties") do not have notice of any adverse claim to those Pledged Shares, the
Collateral Agent has a valid and perfected security interest, for the benefit of
the Secured Parties to secure the Secured Obligations (as defined in the Pledge
Agreement), in all right, title and interest of the Borrower in and to those
Pledged Shares, which security interest has priority over any other security
interest in those Pledged Shares which can be perfected under the Uniform
Commercial Code of the State of New York (the "NY-UCC").

         After giving effect to the making of the Loans on the date of this
letter, the Collateral Agreement creates a valid security interest in favor of
the Collateral Agent, for the benefit of the Secured Parties, to secure the
Obligations (as defined in the Collateral Agreement), in all right, title and
interest of the Borrower in







<PAGE>



and to the Collateral (as defined in the Collateral Agreement), to the extent
that Article 9 of the NY-UCC is applicable (the "Security Interest"). The UCC-1
financing statements listed on Schedule 1 to this letter (the "New York
Financing Statements") are in appropriate form for filing, and the filing
offices listed on Schedule 1 (the "New York Filing Offices") are all of the
offices in New York in which filings are required to perfect the Security
Interest to the extent that it can be perfected by filing under the NY-UCC.
Assuming the New York Financing Statements have been duly presented for filing
to the New York Filing Offices with the appropriate filing fees tendered, or
duly accepted for filing by the appropriate filing officers in each New York
Filing Office, then to the extent that a security interest in the Collateral may
be perfected by filing under the NY-UCC, those filings have resulted in the
perfection of the Security Interest.

         Based solely upon our review described in paragraph (d) below with
respect to the Uniform Commercial Code in effect in California and Nevada (the
"Additional States"), the Security Interest will be perfected in the Additional
States by filing financing statements containing the information set forth in
the New York Financing Statements and in the form required by each Additional
State in the offices set forth on Schedule 2, to the extent that those security
interests can be perfected by filing under the Applicable UCCs (as defined in
paragraph (d) below).

         This opinion is subject to the following assumptions, exceptions and
qualifications:







<PAGE>



         The enforceability of the Documents may be: (i) subject to bankruptcy,
insolvency, reorganization, fraudulent conveyance or transfer, moratorium or
similar laws affecting creditors' rights generally; (ii) subject to general
principles of equity (regardless of whether enforceability is considered in a
proceeding at law or in equity); and (iii) subject to the qualification that
certain remedial provisions of the Collateral Agreement and the Pledge Agreement
(collectively, the "Security Documents") are or may be unenforceable in whole or
in part under the laws of the State of New York, but the inclusion of such
provisions does not make the remedies afforded by the Security Documents
inadequate for the practical realization of the rights and benefits purported to
be provided by the Security Documents except for the economic consequences
resulting from any delay imposed by, or any procedure required by, applicable
New York laws, rules, regulations and court decisions and by constitutional
requirements in and of the State of New York.




         a) We express no opinion as to: (i) the enforceability of any
provisions contained in the Documents that purport to establish (or may be
construed to establish) evidentiary standards; (ii) the enforceability of any
provisions contained in the Security Documents that constitute waivers which are
prohibited under Section 9-501 of the NY-UCC; (iii) the enforceability of forum
selection clauses in the federal courts; or (iv) the enforceability of set-off
rights granted to participants.

         With respect to paragraphs 5, 6 and 7 above, we express no opinion as
to: (i) any Principal Party's right, title or interest in or to any Collateral;
(ii) the laws of any other State or the perfection and effect of perfection or
non-







<PAGE>



perfection of a security interest in the Collateral subject to the laws of
any State other than New York, except as expressly provided in paragraph 7
above; (iii) the perfection of security interests in fixtures, equipment used in
farming operations, farm products, consumer goods, timber or minerals or the
like, or accounts resulting from their sale; or (iv) the creation, validity,
perfection, priority or enforceability of any security interest sought to be
created in any patents, trademarks, trade names, service marks, copyrights,
deposit accounts, insurance policies, real property, motor vehicles or any other
items of property to the extent that a security interest in any of them is
excluded from the coverage of Article 9 of the NY-UCC. In addition, (x) except
as specifically set forth in paragraphs 5, 6 and 7 above, we express no opinion
as to the perfection of any security interest and (y) except as specifically set
forth in paragraph 5 above, we express no opinion as to the priority of any
security interest.

         With respect to the opinions set forth in paragraph 7 above, we do not
purport to be experts in the laws of any State other than the State of New York
and have not obtained opinions of counsel admitted in any other State with
respect to the perfection of the security interests created by the Collateral
Agreement to the extent perfection is governed by the laws of any other State.
In connection with that opinion, however, we have examined the provisions of
Section 9-103 and Section 9-401 of the Uniform Commercial Codes in effect in the
Additional States (the "Applicable UCCs"), as those Sections appear in the
Secured Transactions Guide published by Commerce Clearing House, Inc., updated
through __________ (the "CCH Guide"), and our opinion set forth in paragraph 7,
to the extent it involves conclusions as to







<PAGE>



perfection of security interests under the laws of the Additional States, is
based solely upon that review. We have not reviewed any other provisions of the
Applicable UCCs, nor the constitution nor any other applicable law of the
Additional States, whether statutory, regulatory or case law, in giving this
opinion, nor have we made any independent investigation of the accuracy of the
provisions as published in the CCH Guide.

         We wish to point out that in the case of proceeds (as defined in
Article 9 of the NY-UCC), the continuation of perfection of any security
interest in them is limited to the extent set forth in Section 9-306 of the
NY-UCC. We also wish to point out that the Applicable UCCs may have similar or
other relevant provisions.

         We call to your attention the fact that (i) Article 9 of the NY-UCC
requires the filing of continuation statements within the period of six months
prior to the expiration of each five year period from the date of the original
filing of financing statements, as applicable, in order to maintain the
effectiveness of the filings referred to in this opinion, and (ii) additional
filings may be necessary if any Debtor changes its name, identity or corporate
structure or the jurisdictions in which its places of business, its chief
executive office or the Collateral are located. We also wish to point out that
the Applicable UCCs may have similar or other relevant provisions.

         Except as expressly provided in paragraph 7 above, this opinion is
limited to the laws of the State of New York, and the federal laws of the United
States of America (other than the Federal Communications Act of 1934 and any
other Federal







<PAGE>




or state laws relating to the regulation of satellites or radio stations) that,
in each case, in our experience, are normally applicable to credit transactions
of the type contemplated by the Term Loan Agreement (collectively, the "Covered
Laws"). This opinion is rendered only with respect to the laws, and the rules,
regulations and orders under those laws, that are currently in effect.

         This opinion is furnished by us solely for your benefit in connection
with the transactions referred to in the Term Loan Agreement and may not be
circulated to, or relied upon by, any other Person, except that it may be
circulated to any prospective Lender in accordance with the Term Loan Agreement
and may be relied upon by any person who, in the future, becomes a Lender and
may be disclosed by you to any regulatory agency having authority over a Lender
upon its request.

                                Very truly yours,

To the Lenders party to the
  Credit Agreement referred
  to below and Lehman Commercial
  Paper Inc., as Administrative Agent

Ladies and Gentlemen:

                  I am general counsel to Sirius Satellite Radio Inc., a
Delaware corporation (the "Borrower"), and Satellite CD Radio, Inc., a Delaware
corporation (the "Subsidiary" and, together with the Borrower, the "Principal
Parties"), in connection with the Term Loan Agreement dated as of June 1, 2000
(the "Credit Agreement") among the Borrower, the financial institutions parties
to the Credit Agreement on the date hereof (the "Lenders"), and Lehman
Commercial Paper Inc., as administrative agent (the "Agent"). This opinion is
being furnished to you at the request of the Borrower as provided by Section
4.1(k)(ii) of the Credit Agreement. Capitalized terms used and not otherwise
defined have the respective meanings given those terms in the Credit Agreement.

                  In connection with this opinion, I have examined originals, or
copies certified or otherwise identified to my satisfaction, of the following
documents, each dated as of the date indicated below (collectively, the
"Documents"):

                        the Credit Agreement;

                        the Notes dated as of the date hereof;





<PAGE>



                        the Pledge Agreement dated as of the date hereof; and

                        the Collateral Agreement dated as of the date hereof.

                  In addition, I have examined: (i) the corporate records of the
Principal Parties, including copies of the certificate of incorporation and
by-laws of each Principal Party in effect on the date of this letter
(collectively, the "Charter Documents") and copies of resolutions of the board
of directors of the Borrower; and (ii) those other certificates, agreements and
documents that I deemed relevant and necessary as a basis for my opinion.

                  Based upon the foregoing, and subject to the assumptions,
exceptions and qualifications stated below, I am of the opinion that:

                       Each of the Principal Parties is duly incorporated,
validly existing and in good standing under the laws of the State of Delaware.

                       Each Principal Party has all necessary corporate power
and authority to execute, deliver and perform its obligations under each
Document to which it is a party and has duly executed and delivered each
Document to which it is a party. The execution, delivery and performance by each
Principal Party of each Document to which it is a party have been duly
authorized by all necessary corporate action on the part of the Principal Party
and do not violate its Charter Documents.

                       The execution and delivery by each Principal Party of
each of the Documents to which it is a party and the performance by the
Principal Party of its obligations under the Documents do not (i) violate or
result in a breach of or default under the General Corporation Law of the State
of Delaware, any order, writ, injunction or decree of which I have knowledge of
any court or governmental authority






<PAGE>



or agency binding upon the Principal Party or to which the Principal Party is
subject, or any agreement or instrument filed as an exhibit to the Borrower's
Annual Report on Form 10-K for the year ended December 31, 1999 (other than the
Senior Discount Note Indenture and the Senior Note Indenture) filed with the SEC
to which the Principal Party is a party or by which the Principal Party is
bound, or (ii) result in the creation or imposition of any Lien upon any of the
assets of the Principal Party under the terms of any agreement or instrument
referred to in clause (i) (except for Liens in favor of the Collateral Agent
contemplated by the Documents).

                       To my knowledge, there are no legal proceedings pending
or overtly threatened against the Borrower or any of its Subsidiaries, or to
which the business, assets or property of the Borrower or any of its
Subsidiaries are subject, which are reasonably likely to have a material adverse
effect on the Borrower and its Subsidiaries taken as a whole or on the validity
or enforceability of any of the Documents.

                       All of the shares of Capital Stock described on Schedule
I to the Pledge Agreement are owned of record by the Borrower.

                  I am a member of the bar of the State of New York and do not
express any opinion as to matters governed by any law other than the laws of the
State of New York and the General Corporation Law of the State of Delaware. This
opinion is rendered only with respect to the laws, and the rules, regulations
and orders under those laws, that are currently in effect.

                  This opinion is furnished solely for your benefit in
connection with the transaction referred to in the Credit Agreement and may not
be circulated to, or relied






<PAGE>



upon by, any other Person, except that it may be circulated to any prospective
Lender in accordance with the Credit Agreement and may be relied upon by any
person who, in the future, becomes a Lender and may be disclosed by you to any
regulatory agency having authority over a Lender upon its request.

                                                 Very truly yours,

      Form of Legal Opinion of Wiley, Rein & Fielding, special FCC counsel
                        to Borrower and its Subsidiaries


                                     [DATE]

To the Lenders party to the
Agreement referred to below and
Lehman Commercial Paper Inc.,
as Administrative Agent
c/o Lehman Commercial Paper Inc.
3 World Financial Center
New York, New York 10285

Ladies and Gentlemen:

         We have served as special counsel to Sirius Satellite Radio Inc. ("the
Borrower") solely in connection with Communications Laws (as hereafter defined).
We are furnishing this opinion to you in connection with the $150,000,000 Term
Loan Agreement, dated as of [xxx] (the "Agreement"), among each of the Lenders
from time to time parties thereto, Lehman Brothers Inc. (as "Arranger"), Lehman
Commercial Paper Inc. (as "Syndication Agent" and "Administrative Agent") and
the Borrower, and the Collateral Agreement, dated as of [xxx] (the "Collateral
Agreement"), made by the Borrower in favor of The Bank of New York (as
"Collateral Agent") and the Second Amended and Restated Pledge Agreement, dated
as of [xxx] (the "Pledge Agreement" and, together with the Collateral Agreement,
the "Security Documents," and, collectively with the Agreement, the "Loan
Documents"), among the Borrower, the Administrative Agent, The Bank of New York,
as trustee, United States Trust Company of New York, as trustee, and the
Collateral Agent. Unless otherwise defined herein, capitalized terms defined in
the Loan Documents have the same meanings when used herein.

         In rendering our opinion, we have examined copies of the Loan Documents
provided to us by the Borrower. We have also examined such other documents and
instruments and such questions of law as we have deemed necessary for the
purpose of rendering the opinion set forth herein. Additionally, we have relied
upon the representations made by the Borrower in the Loan Documents and other
documents referred to therein or contemplated thereby, upon the statements of
officers and representatives of the Borrower, and upon records routinely
available for public inspection at the Federal Communications Commission ("FCC")
as of [date]. We have not examined the files or made inquiry of any state
authority. We have assumed the







<PAGE>


Lenders and Lehman Commercial Paper Inc.
DATE
Page 2


completeness of the public files maintained by the FCC and the accuracy and
authenticity of all documents contained therein. With respect to factual matters
relevant to our opinions herein, we have relied upon our review of the Loan
Documents and discussion with officers and representatives of the Borrower of
the factual contents of the Agreement relating to the Communications Laws and
proceedings thereunder, without independent check or verification except as
expressly stated herein.

         Our opinion herein is limited to matters arising under or involving the
Communications Act of 1934, as amended, and the rules, regulations and written
policies promulgated thereunder by the FCC, the International Telecommunication
Union Constitution and Convention dated 1992, and the International Radio
Regulations promulgated thereunder dated 1992 (collectively, "Communications
Laws"). We express no opinion as to (i) matters arising under or involving any
laws other than the Communications Laws, (ii) any jurisdiction other than the
United States, or (iii) any state of the United States.

         Based upon the foregoing:

1.   To the best of our knowledge after due inquiry as described in this letter,
(a) the Borrower and its Subsidiaries hold the FCC authorizations, licenses
and permits (the "FCC Licenses") set forth in Attachment A hereto, and (b)
except as set forth in Attachment A hereto, these FCC Licenses constitute the
only material FCC authorizations required or necessary for the Borrower or any
of its Subsidiaries to operate a satellite digital audio radio service.

2.   Except for any FCC filings or approvals which may be necessary prior to the
exercise of any remedies under the Loan Documents in the event of default by the
Borrower or any of its Subsidiaries and except for any informational filings
which may be required, (a) the execution, delivery, and performance according
to the terms of the Loan Documents, the consummation of the secured loan
transaction contemplated therein, the granting of the security interests under
the Security Documents and compliance by the Borrower or its Subsidiaries with
their obligations under the Loan Documents do not violate the Communications
Laws and (b) no consent, approval, authorization, or order of or filing with the
FCC is necessary for the execution, delivery, and performance of the Loan
Documents except for such consents, approvals, authorizations, or orders or
filings as have already been obtained or made and remain in full force and
effect and except to the extent that the failure to obtain such consents,
approvals, authorizations, or orders or to make such filings would not,
individually or in the aggregate, have a material adverse effect on the FCC
Licenses.

3.   To the best of our knowledge after due inquiry as described in this letter,
(a) no adverse judgment, decree, or order of the FCC has been issued against the
Borrower or







<PAGE>



Lenders and Lehman Commercial Paper Inc.
DATE
Page 3

any of its Subsidiaries and (b) except as set forth in Attachment A and except
for proceedings of general applicability to the industry, such as but not
limited to any future proceeding as to the public interest responsibilities of
the satellite digital audio radio service operators, no litigation, proceeding,
inquiry or investigation has been commenced against the Borrower or any of its
Subsidiaries before or by the FCC which, if decided adversely to the Borrower's
or such Subsidiary's interest, could reasonably be expected to have a material
adverse effect on the FCC Licenses.

4.   Except as set forth in Attachment A and except for any further filings
relating to the Borrower's change to a three satellite system, to the best of
our knowledge after due inquiry as described in this letter, each of the
Borrower and its Subsidiaries has made all material reports and filings and paid
all fees required to date by the FCC necessary for the Borrower or any of its
Subsidiaries to operate a satellite digital audio radio service.

5.   To the best of our knowledge after due inquiry as described in this letter,
the FCC has not issued to the Borrower or any of its Subsidiaries any
qualification or rejection of any report or filing, the effect of which,
individually or in the aggregate, would have a material adverse effect on the
FCC Licenses.

         This opinion is being furnished to you subject to the qualifications
and limitations expressed herein, and has been prepared solely for the use and
benefit of the Lenders and the Administrative Agent in connection with the
Agreement and may be disclosed by you to your auditors, bank regulators (to the
extent required in connection with the Loan Documents) and professional
advisors. This opinion may not be quoted in whole or in part or otherwise
referred to, or furnished to any governmental agency or other entity or person,
without our written consent, except as provided in the preceding sentence and
except that this opinion may be circulated to any prospective Lender in
accordance with the Agreement. It may not be used by any other person or entity
without our written consent, and may be relied upon by the Lenders, the
Administrative Agent and its counsel only with respect to the specific matters
which are

the subject hereof. The opinion expressed herein is as of the date hereof, and
we assume no obligation to advise you of any changes in the foregoing opinion.

                                                     Very truly yours,

                                  Attachment A

The Borrower or its Subsidiaries hold the following Licenses necessary for the
operation of a satellite digital audio radio service:

1.   Authorization to construct, launch and operate two satellites in the
     satellite digital audio radio service (Granted Oct. 10, 1997; subject to
     Petition for Review and not administratively final).

2.   Special Temporary Authorization to launch three satellites into inclined
     and elliptical (non-geostationary) orbits and to test satellites (Granted
     Dec. 20, 1999; Renewed Apr. 12, 2000).


The Borrower or its Subsidiaries have applied for but does not hold the
following FCC Licenses necessary for the operation of a satellite digital audio
