preamble, recitals, exhibits and schedules hereto, shall have the following
meanings:

to the acquisition thereof by Company or any of its Subsidiaries or Indebtedness

after the date hereof existing prior to such merger or consolidation or the time
such Person becomes a Subsidiary of Company; provided that such Indebtedness is
not incurred in contemplation of or in connection with such acquisition, merger
or consolidation or with such Person becoming a Subsidiary, as the case may be.
For the avoidance of doubt, Acquired Debt includes Indebtedness issuable upon
the exchange of Acquired Preferred Stock or other Acquired Debt in accordance
with the terms thereof.

     "Acquired Investment" means an Investment owned by a Person prior to the
time such Person merges with or into or consolidates with Company or any of its
Subsidiaries or becomes a Subsidiary (otherwise than by RS Designation) of

contemplation of or in connection with such merger or consolidation or with such
Person becoming a Subsidiary, as the case may be.

     "Acquired Preferred Stock" means preferred stock of any Person that merges
with or into or consolidates with Company or any of its Subsidiaries or becomes
a Subsidiary (otherwise than by RS Designation) of Company after the date hereof
existing prior to such merger or consolidation or the time such Person becomes a
Subsidiary; provided that such preferred stock is not issued in contemplation of
or in connection with such merger or consolidation or with such Person becoming
a Subsidiary, as the case may be.

     "Additional Capital" means, in each case as issued after October 20, 1999,
(a) common stock of Company, (b) preferred stock of Company having covenants,
remedies, required payment, required redemption and other similar non-economic

Company than Company's Preferred Stock outstanding or contracted to be issued as
of the Closing Date and having no requirement for any mandatory redemption
(other than any mandatory redemption pursuant to customary "change of control"
provisions similar to those contained in the Existing Indentures) prior to June
30, 2008 and (c) unsecured indebtedness of Company having covenants, defaults,
remedies, required

<PAGE>

prepayment, required redemption and other similar non-economic terms and
provisions not materially more restrictive on or less favorable to Company than

(other than mandatory repayments pursuant to customary "change of control" or
asset sale provisions similar to those contained in the Existing Indentures)
earlier than June 30, 2008; provided that, not more than $850,000,000 of
Additional Capital shall constitute Indebtedness (determined without regard to
the accretion of discount or the accrual of interest); and provided further that
the amount included in the calculation of "Additional Capital" in respect of any
issuance of Preferred Stock shall equal the proceeds of such issuance less an
amount, if any, equal to the discounted present value of all Cash dividends
payable by Company during the term of this Agreement on such Preferred Stock,
such calculation to be determined using a discount rate equal to the dividend
rate of the stock for which dividends are to be paid.

     "Adjusted EBITDA" means, for any period, an amount determined for a
Geographic Market, to the extent that such amount is a positive number, equal to
the total revenues for such period (less provisions for any credit reserves

period; as calculated for each Fiscal Quarter for such Geographic Market, on a
basis which excludes all amounts attributable to corporate and regional overhead
expense of Company and its Subsidiaries (other than the Subsidiary which

allocable to such Geographic Market), and in a manner consistent with the
calculations made and delivered pursuant to Section 3.1(g) on the Closing Date.

     "Adjusted Eurodollar Rate" means, for any Interest Rate Determination Date

annum obtained by dividing (and rounding upward to the next whole multiple of

page number 3740 or 3750, as applicable) for deposits (for delivery on the first
day of such period) with a term equivalent to such period in Dollars, determined

of such period) with a term equivalent to such period in Dollars, determined as

Determination Date, or (c) in the event the rates referenced in the preceding

the London interbank market by TD for deposits (for delivery on the first day of
the relevant period) in Dollars of amounts in same day funds comparable to the
principal amount of the applicable Loan of Administrative Agent, in its capacity
as a Lender, for which the Adjusted Eurodollar Rate is then being determined
with maturities comparable to such

SECTION 2. LOANS

     2.1. Term Loans.

          (a) Loan Commitments. Subject to the terms and conditions hereof,

               (i) each Lender severally agrees to make (i) on the Closing Date
          a Tranche A Term Loan to Company in an amount equal to its Pro Rata
          Share of $150,000,000 and (ii) at any time prior to the Tranche A
          Commitment Termination Date, additional Tranche A Term Loans in an
          aggregate amount not to exceed such Lender's Tranche A Term Loan
          Commitment; and

               (ii) each Lender severally agrees to make, on the Closing Date,
          subject to Section 2.23, a Tranche B Term Loan to Company in an amount
          equal to such Lender's Tranche B Term Loan Commitment.

Company may make only one borrowing under the Tranche B Term Loan Commitment
which shall be on the Closing Date. Company may make one or more Tranche A Term
Loan borrowings after the Closing Date and prior to the Tranche A Commitment
Termination Date (each such borrowing date, a "Tranche A Subsequent Funding
Date"). Any amount borrowed under this Section 2.1(a) and subsequently repaid or
prepaid may not be reborrowed. Subject to Sections 2.11(a) and 2.12, all amounts
owed hereunder with respect to the Tranche A Term Loans and the Tranche B Term
Loans shall be paid in full no later than the Tranche A Term Loan Maturity Date
and the Tranche B Term Loan Maturity Date, respectively. Each Lender's Tranche

<PAGE>

B Term Loan Commitment shall terminate immediately and without further action on
the Closing Date after giving effect to the funding of such Tranche B Term Loan
Commitment on such date. Each Lender's Tranche A Term Loan Commitment shall
terminate on the Tranche A Commitment Termination Date.

          (b) Borrowing Mechanics for Term Loans. (i) Company shall deliver to
     Administrative Agent a fully executed and delivered (A) Closing Date
     Certificate (which shall be deemed to be a Funding Notice with respect to
     the Term Loans to be funded on the Closing Date for all purposes hereof) no
     later than 10:00 a.m. (New York City time) at least three Business Days in
     advance of the Closing Date in the case of a Term Loan which is a
     Eurodollar Rate Loan, and at least one Business Day in advance of the
     Closing Date in the case of a Term Loan that is a Base Rate Loan and (B)
     Funding Notice no later than 10:00 a.m. (New York City time) at least three
     Business Days in advance of each Tranche A Subsequent Funding Date in the
     case of a Tranche A Term Loan which is a Eurodollar Rate Loan, and at least
     one Business Day in advance of each Tranche A Subsequent Funding Date in
     the case of a Tranche A Term Loan that is a Base Rate Loan. Promptly upon
     receipt by Administrative Agent of such Certificate or Notice, as
     applicable, Administrative Agent shall notify each Lender of the proposed
     borrowing.

          (ii) Each Lender shall make its Tranche A Term Loan and Tranche B Term
     Loan, as the case may be, available to Administrative Agent not later than
     12:00 p.m. (New York City time) on the Closing Date, or each Tranche A
     Subsequent Funding Date, as applicable, by wire transfer of same day funds
     in Dollars, at Administrative Agent's Principal Office. Upon satisfaction
     or waiver of the conditions precedent specified herein, Administrative
     Agent shall make the proceeds of the Term Loans available to Company on the
     Closing Date, or each Tranche A Subsequent Funding Date, as applicable, by
     causing an amount of same day funds in Dollars equal to the proceeds of all
     such Loans received by Administrative Agent from Lenders to be credited to
     the account of Company at Administrative Agent's Principal Office or to
     such other account as may be designated in writing to Administrative Agent
     by Company.

     2.2. Revolving Loans.

     (a) Revolving Credit Commitments. During the Revolving Credit Commitment
Period, subject to the terms and conditions hereof, each Lender severally agrees
to make Revolving Loans to Company in the aggregate amount up to but not
exceeding such Lender's Revolving Credit Commitment; provided, after giving
effect to the making of any Revolving Loans in no event shall the total
Revolving Loans exceed the Revolving Credit Commitments then in effect. Amounts
borrowed pursuant to this Section 2.2(a) may be repaid and reborrowed during the
Revolving Credit Commitment Period. Each Lender's Revolving Credit Commitment
shall expire on the Revolving Credit Commitment Termination Date and all
Revolving Loans and all other amounts owed hereunder with respect to the
Revolving Loans and the Revolving Credit Commitments shall be paid in full no
later than such date.

<PAGE>

          (b) Borrowing Mechanics for Revolving Loans. (i) Revolving Loans shall
     be in an aggregate minimum amount of $5,000,000 and integral multiples of
     $1,000,000 in excess of that amount.

          (ii) Whenever Company desires that Lenders make Revolving Loans,
     Company shall deliver to Administrative Agent a fully executed and
     delivered Funding Notice no later than 10:00 a.m. (New York City time) at
     least three Business Days in advance of the proposed Credit Date in the
     case of a Eurodollar Rate Loan, and at least one Business Day in advance of
     the proposed Credit Date in the case of a Revolving Loan that is a Base
     Rate Loan. Except as otherwise provided herein, a Funding Notice for a
     Revolving Loan that is a Eurodollar Rate Loan shall be irrevocable on and
     after the related Interest Rate Determination Date, and Company shall be
     bound to make a borrowing in accordance therewith.

          (iii) Notice of receipt of each Funding Notice in respect of Revolving
     Loans, together with the amount of each Lender's Pro Rata Share thereof, if
     any, together with the applicable interest rate, shall be provided by
     Administrative Agent to each applicable Lender by telefacsimile with
     reasonable promptness, but (provided Administrative Agent shall have
     received such notice by 10:00 a.m. (New York City time)) not later than
     2:00 p.m. (New York City time) on the same day as Administrative Agent's
     receipt of such Notice from Company.

          (iv) Each Lender shall make the amount of its Revolving Loan available
     to Administrative Agent not later than 12:00 p.m. (New York City time) on
     the applicable Credit Date by wire transfer of same day funds in Dollars,
     at the Administrative Agent's Principal Office. Except as provided herein,
     upon satisfaction or waiver of the conditions precedent specified herein,
     Administrative Agent shall make the proceeds of such Revolving Loans
     available to Company on the applicable Credit Date by causing an amount of
     same day funds in Dollars equal to the proceeds of all such Revolving Loans
     received by Administrative Agent from Lenders to be credited to the account
     of Company at the Administrative Agent's Principal Office or such other
     account as may be designated in writing to Administrative Agent by Company.

     2.3. Pro Rata Shares; Availability of Funds.

     (a) Pro Rata Shares. All Loans shall be made, and all participations
purchased, by Lenders simultaneously and proportionately to their respective Pro
Rata Shares, it being understood that no Lender shall be responsible for any
default by any other Lender in such other Lender's obligation to make a Loan
requested hereunder or purchase a participation required hereby nor shall the
Revolving Credit Commitment of any Lender be increased or decreased as a result
of a default by any other Lender in such other Lender's obligation to make a
Loan requested hereunder or purchase a participation required hereby.

     (b) Availability of Funds. Unless Administrative Agent shall have been
notified

<PAGE>

by any Lender prior to the applicable Credit Date that such Lender does not
intend to make available to Administrative Agent the amount of such Lender's
Loan requested on such Credit Date, Administrative Agent may assume that such
Lender has made such amount available to Administrative Agent on such Credit
Date and Administrative Agent may, in its sole discretion, but shall not be
obligated to, make available to Company a corresponding amount on such Credit
Date. If such corresponding amount is not in fact made available to
Administrative Agent by such Lender, Administrative Agent shall be entitled to
recover such corresponding amount on demand from such Lender together with
interest thereon, for each day from such Credit Date until the date such amount
is paid to Administrative Agent, at the customary rate set by Administrative
Agent for the correction of errors among banks for three Business Days and
thereafter at the Base Rate. If such Lender does not pay such corresponding
amount forthwith upon Administrative Agent's demand therefor, Administrative
Agent shall promptly notify Company and Company shall immediately pay such
corresponding amount to Administrative Agent together with interest thereon, for
each day from such Credit Date until the date such amount is paid to
Administrative Agent, at the rate payable hereunder for Base Rate Loans for such
Class of Loans. Nothing in this Section 2.3(b) shall be deemed to relieve any
Lender from its obligation to fulfill its Revolving Credit Commitments hereunder
or to prejudice any rights that Company may have against any Lender as a result
of any default by such Lender hereunder.

     2.4. Use of Proceeds. Up to $125,000,000 (or such greater amount as may be
permitted under the Public Indentures) of the proceeds of the Loans will be used
to finance capital expenditures, to provide working capital and for other
general corporate purposes, and all remaining Loan proceeds (including all New
Revolving Loans and New Term Loans, if any) will be used to provide purchase
money financing for the construction, acquisition or improvement of
Telecommunication Assets not to exceed 80% (or such greater percentage (not in
excess of 100%) as may be permitted under the Public Indentures) of the total
cost of the assets financed thereby. No portion of the proceeds of any Loan
shall be used by Company or any of its Subsidiaries in any manner that might
cause such Loan or the application of such proceeds to violate Regulation T,
Regulation U or Regulation X of the Board of Governors of the Federal Reserve
System or any other regulation thereof or to violate the Exchange Act, in each
case as in effect on the date or dates of such Loan and such use of proceeds.

     2.5. Evidence of Debt; Register; Lenders' Books and Records; Notes.

     (a) Lenders' Evidence of Debt. Each Lender shall maintain on its internal
records an account or accounts evidencing the Indebtedness of Company to such
Lender, including the amounts of the Loans made by it and each repayment and
prepayment in respect thereof. Any such recordation shall be conclusive and
binding on Company, absent manifest error; provided, failure to make any such
recordation, or any error in such recordation, shall not affect any Lender's
Revolving Credit Commitments or Company's Obligations in respect of any
applicable Loans; and provided further, in the event of any inconsistency
between the Register and any Lender's records, the recordations in the Register
shall govern.

     (b) Register. Administrative Agent shall maintain at its Principal Office a

<PAGE>

register for the recordation of the names and addresses of Lenders and the
Revolving Credit Commitments and Loans of each Lender from time to time (the
"Register"). The Register shall be available for inspection by Company or any
Lender at any reasonable time and from time to time upon reasonable prior
notice. Administrative Agent shall record in the Register the Revolving Credit
Commitments, the Tranche A Term Loan Commitments and the Loans, and each
repayment or prepayment in respect of the principal amount of the Loans, and any
such recordation shall be conclusive and binding on Company and each Lender,
absent manifest error; provided, failure to make any such recordation, or any
error in such recordation, shall not affect any Lender's Revolving Credit
Commitments, Tranche A Term Loan Commitments or Company's Obligations in respect
of any Loan. Company hereby designates TD to serve as Company's agent solely for
purposes of maintaining the Register as provided in this Section 2.5, and
Company hereby agrees that, to the extent TD serves in such capacity, TD and its
officers, directors, employees, agents and affiliates shall constitute
"Indemnitees."

     (c) Notes. If so requested by any Lender by written notice to Company (with
a copy to Administrative Agent) at least two Business Days prior to the Closing
Date, or at any time thereafter, Company shall execute and deliver to such
Lender (and/or, if applicable and if so specified in such notice, to any Person
who is an assignee of such Lender pursuant to Section 10.6) on the Closing Date
(or, if such notice is delivered after the Closing Date, promptly after
Company's receipt of such notice) a Note or Notes to evidence such Lender's
Tranche A Term Loan, Tranche B Term Loan or Revolving Loan, as the case may be.

     2.6. Interest on Loans.

     (a) Except as otherwise set forth herein, each Class of Loan shall bear
interest on the unpaid principal amount thereof from the date made through
repayment (whether by acceleration or otherwise) thereof as follows:

          (i) in the case of Tranche A Term Loans and Revolving Loans:

               (1) if a Base Rate Loan, at the Base Rate plus the Applicable
          Margin; or

               (2) if a Eurodollar Rate Loan, at the Adjusted Eurodollar Rate
          plus the Applicable Margin; and

          (ii) in the case of Tranche B Term Loans:

               (1) if a Base Rate Loan, at the Base Rate plus 2.25% per annum;
          or

               (2) if a Eurodollar Rate Loan, at the Adjusted Eurodollar Rate
          plus 3.25% per annum.

<PAGE>

     (b) The basis for determining the rate of interest with respect to any
Loan, and the Interest Period with respect to any Eurodollar Rate Loan, shall be
selected by Company and notified to Administrative Agent and Lenders pursuant to
the applicable Funding Notice or Conversion/Continuation Notice, as the case may
be; provided, (A) until the date which is 7 days following the Closing Date the
Term Loans shall be maintained as Base Rate Loans and (B) from the date which is
8 days following the Closing Date until the date which is 90 days following the
Closing Date the Term Loans shall be maintained as either (1) Eurodollar Rate
Loans having an Interest Period of no longer than one month or (2) Base Rate
Loans. If on any day a Loan is outstanding with respect to which a Funding
Notice or Conversion/Continuation Notice has not been delivered to
Administrative Agent in accordance with the terms hereof specifying the
applicable basis for determining the rate of interest, then for that day such
Loan shall be a Base Rate Loan.

     (c) In connection with Eurodollar Rate Loans there shall be no more than
ten (10) Interest Periods outstanding at any time. In the event Company fails to
specify between a Base Rate Loan or a Eurodollar Rate Loan in the applicable
Funding Notice or Conversion/Continuation Notice, such Loan (if outstanding as a
Eurodollar Rate Loan) will be automatically converted into a Base Rate Loan on
the last day of the then-current Interest Period for such Loan (or if
outstanding as a Base Rate Loan will remain as, or (if not then outstanding)
will be made as, a Base Rate Loan). In the event Company fails to specify an
Interest Period for any Eurodollar Rate Loan in the applicable Funding Notice or
Conversion/Continuation Notice, Company shall be deemed to have selected an
Interest Period of one month. A soon as practicable after 10:00 a.m. (New York
City time) on each Interest Rate Determination Date, Administrative Agent shall
determine (which determination shall, absent manifest error, be final,
conclusive and binding upon all parties) the interest rate that shall apply to
the Eurodollar Rate Loans for which an interest rate is then being determined
for the applicable Interest Period and shall promptly give notice thereof (in
writing or by telephone confirmed in writing) to Company and each Lender.

     (d) Interest payable pursuant to Section 2.6(a) shall be computed (i) in
the case of Base Rate Loans on the basis of a 365-day or 366-day year, as the
case may be, and (ii) in the case of Eurodollar Rate Loans, on the basis of a
360-day year, in each case for the actual number of days elapsed in the period
during which it accrues. In computing interest on any Loan, the date of the
making of such Loan or the first day of an Interest Period applicable to such
Loan or, with respect to a Base Rate Loan being converted from a Eurodollar Rate
Loan, the date of conversion of such Eurodollar Rate Loan to such Base Rate
Loan, as the case may be, shall be included, and the date of payment of such
Loan or the expiration date of an Interest Period applicable to such Loan or,
with respect to a Base Rate Loan being converted to a Eurodollar Rate Loan, the
date of conversion of such Base Rate Loan to such Eurodollar Rate Loan, as the
case may be, shall be excluded; provided, if a Loan is repaid on the same day on
which it is made, one day's interest shall be paid on that Loan.

     (e) Except as otherwise set forth herein, interest on each Loan shall be
payable in arrears on and to (i) each Interest Payment Date applicable to that
Loan; (ii) any prepayment of

<PAGE>

that Loan, whether voluntary or mandatory, to the extent accrued on the amount
being prepaid; and (iii) at maturity, including final maturity; provided,
however, with respect to any prepayment of a Base Rate Loan, accrued interest
shall instead be payable on the applicable Interest Payment Date.

     2.7. Conversion/Continuation.

     (a) Subject to Section 2.16 and so long as no Default or Event of Default
shall have occurred and then be continuing, Company shall have the option:

          (i) to convert at any time all or any part of any Term Loan or
     Revolving Loan equal to $5,000,000 and integral multiples of $1,000,000 in
     excess of that amount from one Type of Loan to another Type of Loan;
     provided, a Eurodollar Rate Loan may only be converted on the expiration of
     the Interest Period applicable to such Eurodollar Rate Loan unless Company
     shall pay all amounts due under Section 2.16 in connection with any such
     conversion; or

          (ii) upon the expiration of any Interest Period applicable to any
     Eurodollar Rate Loan, to continue all or any portion of such Loan equal to
     $5,000,000 and integral multiples of $1,000,000 in excess of that amount as
     a Eurodollar Rate Loan.

     (b) The Company shall deliver a Conversion/Continuation Notice to
Administrative Agent no later than 10:00 a.m. (New York City time) at least one
Business Day in advance of the proposed conversion date (in the case of a
conversion to a Base Rate Loan) and at least three Business Days in advance of
the proposed conversion/continuation date (in the case of a conversion to, or a
continuation of, a Eurodollar Rate Loan). Except as otherwise provided herein, a
Conversion/Continuation Notice for conversion to, or continuation of, any
Eurodollar Rate Loans (or telephonic notice in lieu thereof) shall be
irrevocable on and after the related Interest Rate Determination Date, and
Company shall be bound to effect a conversion or continuation in accordance
therewith.

     2.8. Default Interest. Upon the occurrence and during the continuance of an
Event of Default described in Section 8.1 (a), the principal amount of all Loans
and, to the extent permitted by applicable law, any interest payments on the
Loans or any fees or other amounts owed hereunder not paid when due, in each
case whether at stated maturity, by notice of prepayment, by acceleration or
otherwise, shall thereafter bear interest (including post-petition interest in
any proceeding under the Bankruptcy Code or other applicable bankruptcy laws)
payable on demand at a rate that is 2% per annum in excess of the interest rate
otherwise payable hereunder with respect to the applicable Loans (or, in the
case of any such fees and other amounts, at a rate which is 2% per annum in
excess of the interest rate otherwise payable hereunder for Revolving Loans
which are Base Rate Loans); provided, in the case of Eurodollar Rate Loans, upon
the expiration of the Interest Period in effect at the time any such increase in
interest rate is effective such Eurodollar Rate Loans shall thereupon become
Base Rate Loans and shall thereafter bear interest payable upon demand at a rate
which is 2% per annum in excess of the interest rate

<PAGE>

otherwise payable hereunder for Revolving Loans which are Base Rate Loans.
Payment or acceptance of the increased rates of interest provided for in this
Section 2.8 is not a permitted alternative to timely payment and shall not
constitute a waiver of any Event of Default or otherwise prejudice or limit any
rights or remedies of Administrative Agent or any Lender.

     2.9. Fees.

     (a) Company agrees to pay to Lenders having Revolving Credit Exposure
commitment fees equal to (1) the average of the daily difference between (a) the
Revolving Credit Commitments, and (b) the aggregate principal amount of
outstanding Revolving Loans multiplied by (2) the Applicable Commitment Fee
Percentage. All fees referred to in this Section 2.9(a) shall be paid to
Administrative Agent at its Principal Office and upon receipt, Administrative
Agent shall promptly distribute to each Lender its Pro Rata Share thereof.

     (b) Company agrees to pay to Lenders having Tranche A Term Loan Exposure
commitment fees equal to (1) the average of the daily difference between (a) the
Tranche A Term Loan Commitments, and (b) the aggregate principal amount of
outstanding Tranche A Term Loans multiplied by (2) the Applicable Commitment Fee
Percentage. All fees referred to in this Section 2.9(b) shall be paid to
Administrative Agent at its Principal Office and upon receipt, Administrative
Agent shall promptly distribute to each Lender its Pro Rata Share thereof.

     (c) All fees referred to in Section 2.9(a) and (b) shall be calculated on
the basis of a 360-day year and the actual number of days elapsed and shall be
payable quarterly in arrears on March 31, June 30, September 30 and December 31
of each year during (i) with respect to Revolving Credit Exposure, the Revolving
Credit Commitment Period, and (ii) with respect to Tranche A Term Loan Exposure,
the Tranche A Commitment Period, commencing in each case on the first such date
to occur after the Closing Date, and ending on the Revolving Credit Commitment
Termination Date or the Tranche A Commitment Termination Date, as applicable.

     (d) In addition to any of the foregoing fees, Company agrees to pay to
Agents such other fees in the amounts and at the times separately agreed upon.

     2.10. Scheduled Payments/Commitment Reductions.

     (a) Scheduled Payments of Tranche A Term Loans. The principal amounts of
the Tranche A Term Loans shall be repaid in the aggregate annual amounts
(expressed as percentages of the Tranche A Term Loan Commitment) set forth below
in consecutive quarterly installments (each, an "Installment") on the last day
of each Fiscal Quarter (each, an "Installment Date") occurring in each of the
Fiscal Years set forth below, commencing March 31, 2004, with 25% of each annual
amount being paid on each Installment Date:

Notwithstanding the foregoing, (i) such Installments shall be reduced in
connection with any voluntary or mandatory prepayments of the Tranche A Term
Loans in accordance with Section 2.13, (ii) the Tranche A Term Loans, together
with all other amounts owed hereunder with respect thereto, shall be paid in
full no later than the Tranche A Term Loan Maturity Date, it being understood
that such date will be October 31, 2005 if the notice specified in Section
5.1(k)(i) has not been received by the Administrative Agent prior to April 15,
2005 and (iii) any additional Tranche A Term Loans will be subject to repayment

additional Loans.

     in writing to Administrative Agent (and Administrative Agent will promptly
     transmit such telephonic or original notice by telefacsimile or telephone
     to each Lender). Upon the giving of any such notice, the principal amount
     of the Loans specified in such notice shall become due and payable on the
     prepayment date specified therein.

          (iii) All prepayments relating to New Term Loans and New Revolving
     Loans shall be made upon such notice as specified in the applicable Joinder

          (b) Voluntary Commitment Reductions. (i) Company may, upon not less
     than three Business Days' prior written or telephonic notice confirmed in
     writing to Administrative Agent (which original written or telephonic
     notice Administrative Agent will promptly transmit by telefacsimile or
     telephone to each applicable Lender), at any time and from time to time
     terminate in whole or permanently reduce in part, without premium or
     penalty:

          (1) undrawn Revolving Credit Commitments; and/or

          (2) undrawn Tranche A Term Loan Commitments;

     provided, any such partial reduction of Revolving Credit Commitments or

     of that amount.

          (ii) Company's notice to Administrative Agent shall designate the date
     (which shall be a Business Day) of such termination or reduction and the
     amount of any partial reduction, and such termination or reduction of
     Revolving Credit Commitments and/or Tranche A Term Loan Commitments shall
     be effective on the date specified in Company's notice and shall reduce the
     Revolving Credit Commitment and/or the Tranche A Term Loan Commitment, as
     applicable, of each Lender proportionately to its Pro Rata Share thereof.

          (iii) Company may, upon the terms and procedures specified in the
     applicable Joinder Agreement, terminate in whole or permanently reduce in
     part, without

<PAGE>

               (2) undrawn New Term Loan Commitments.

     2.12. Mandatory Prepayments/Commitment Reductions.

     (a) Asset Sales. If, within the period of two hundred seventy (270) days
prior to or after the receipt by Company or any of its Subsidiaries of Net Asset
Sale Proceeds, Company has not invested such Net Asset Sale Proceeds in the
business of Company and its Subsidiaries (including, without limitation,
investments in Joint Ventures, Unrestricted Subsidiaries and minority interests
in other entities pursuant to Section 6.5(i)), as certified to Administrative
Agent by Company, then, to the extent Company has not previously done so, (x)
Company shall prepay Loans and/or (y) the Commitments shall be permanently
reduced as set forth in Section 2.13(b), in either case in an amount equal to
the excess of such Net Asset Sale Proceeds over amounts invested as aforesaid.
Pending a determination whether any Net Asset Sale Proceeds will be applied to
prepay Loans and/or reduce Commitments pursuant to the preceding sentence, such
Net Asset Sale Proceeds shall be applied to prepay outstanding Revolving Loans
and/or New Revolving Loans, but not to reduce Revolving Credit Commitments or
New Revolving Credit Commitments.

     (b) Insurance/Condemnation Proceeds. If, within the period of two hundred
seventy (270) days prior to or after the receipt by Company or any of its
Subsidiaries of Net Insurance/Condemnation Proceeds (whether from the insurer,
condemnor, transferee or the Administrative Agent as loss payee), Company has
not invested such Net Insurance/Condemnation Proceeds in the business of Company
and its Subsidiaries (including, without limitation, investments in Joint
Ventures, Unrestricted Subsidiaries and minority interests in other entities
pursuant to Section 6.5(i)), as certified to Administrative Agent by Company,
then, to the extent Company has not previously done so, (x) Company shall prepay
the Loans and/or (y) the Commitments shall be permanently reduced as set forth
in Section 2.13(b), in either case in an amount equal to the excess of such Net
Insurance/Condemnation Proceeds over amounts invested as aforesaid. Pending a
determination whether any Net Insurance/Condemnation Proceeds will be applied to
prepay Loans and/or reduce Commitments, such Net Insurance/Condemnation Proceeds
shall be applied to prepay outstanding Revolving Loans and/or New Revolving
Loans, but not to reduce Revolving Credit Commitments or New Revolving Credit
Commitments.

     (c) Consolidated Excess Cash Flow. In the event that there shall be
Consolidated Excess Cash Flow for any Fiscal Year (commencing with Fiscal Year
2004), no later than one hundred (100) days after the end of such Fiscal Year,
(x) Company shall prepay the Loans and/or (y) the Revolving Credit Commitments,
the New Revolving Credit Commitments, the Tranche A Term Loan Commitments and
the New Term Loan Commitments shall be permanently reduced as set forth in
Section 2.13(b) in an aggregate amount equal to 50% of such

<PAGE>

Consolidated Excess Cash Flow.

     (d) Change of Control. No later than the third Business Day following the
date that a Change of Control shall occur, Company shall prepay, in full, the
outstanding principal amount of all outstanding Loans, together with all accrued
interest, fees and other expenses owing hereunder and under the other Credit
Documents, and all Commitments shall terminate.

     (e) Revolving Loans; New Revolving Loans. Company shall from time to time
prepay the (x) Revolving Loans to the extent necessary so that the outstanding
Revolving Loans shall not at any time exceed the Revolving Credit Commitments
then in effect and (y) New Revolving Loans to the extent necessary so that the
outstanding New Revolving Loans shall not at any time exceed the New Revolving
Credit Commitments then in effect.

     (f) Prepayment Certificate. Concurrently with any prepayment of the Loans
and/or reduction of any Commitments pursuant to Sections 2.12(a) through
2.12(c), Company shall deliver to Administrative Agent a certificate of an
Authorized Officer demonstrating the calculation of the amount of the applicable
net proceeds or Consolidated Excess Cash Flow, as the case may be, that is being
so applied. In the event that Company shall subsequently determine that the
actual amount required to be so applied exceeded the amount set forth in such
certificate, Company shall promptly make an additional prepayment of the Loans
and/or the Commitments shall be permanently reduced in an amount equal to such
excess, and Company shall concurrently therewith deliver to Administrative Agent
a certificate of an Authorized Officer demonstrating the derivation of such
excess.

     2.13. Application of Prepayments/Reductions.

     (a) Application of Voluntary Prepayments. Any prepayment pursuant to
Section 2.11(a) shall be applied to the Loans of the Class or Classes specified
by Company to Administrative Agent; provided that

     (i)  any prepayment of Revolving Loans or New Revolving Loans shall be
          applied to all such Loans then outstanding on a pro rata basis (in
          accordance with the respective outstanding aggregate principal amounts
          of each Class thereof), and

     (ii) any prepayment of Term Loans shall be applied to all such Loans then
          outstanding on a pro rata basis (in accordance with the respective
          outstanding aggregate principal amounts of each Class thereof) but
          subject to Section 2.13(c), with credit given first to the next
          scheduled installment of each thereof and the balance, if any,
          credited on a pro rata basis to each remaining scheduled installment
          of each thereof.

     (b) Application of Mandatory Prepayments by Type of Loans. Any amount
required to be prepaid pursuant to Sections 2.12(a) through 2.12(c) shall be
applied:

<PAGE>

          first, to prepay the Term Loans then outstanding on a pro rata basis
     (in accordance with the respective outstanding aggregate principal amounts
     of each Class thereof), but subject to Section 2.13(c), with credit given
     first to the next scheduled installment of each thereof and the balance, if
     any, credited on a pro rata basis to each remaining scheduled installment
     of each thereof;

          second, to reduce permanently any undrawn Term Loan Commitments on a
     pro rata basis (in accordance with the respective undrawn principal amounts
     of each Class thereof), with credit given first to the next scheduled
     reduction of each thereof and the balance, if any, credited on a pro rata
     basis to each remaining scheduled reduction of each thereof;

          third, to prepay the Revolving Loans and the New Revolving Loans on a
     pro rata basis (in accordance with the respective outstanding principal
     amounts of each Class thereof) and to reduce permanently the Revolving
     Credit Commitment and New Revolving Credit Commitments in the amounts so
     prepaid; and

          fourth, to reduce permanently any undrawn Revolving Credit Commitments
     and New Revolving Credit Commitments on a pro rata basis (in accordance
     with the respective undrawn principal amounts of each Class thereof), with
     credit given first to the next scheduled reduction of each thereof and the
     balance, if any, credited on a pro rata basis to each remaining scheduled
     reduction of each thereof.

     (c) Waivable Mandatory Prepayment. Anything contained herein to the
contrary notwithstanding, so long as any Tranche A Term Loans or New Term Loans
are outstanding or undrawn Term Loan Commitments remain in effect, in the event
Company is required to make any mandatory prepayment (a "Waivable Mandatory
Prepayment") of the Tranche B Term Loans, not less than three Business Days
prior to the date (the "Required Prepayment Date") on which Company is required
to make such Waivable Mandatory Prepayment, Company shall notify Administrative
Agent of the amount of such prepayment, and Administrative Agent will promptly
thereafter notify each Lender holding an outstanding Tranche B Term Loan of the
amount of such Lender's Pro Rata Share of such Waivable Mandatory Prepayment and
such Lender's option to refuse such amount. Each such Lender may exercise such
option by giving written notice to Company and Administrative Agent of its
election to do so on or before the first Business Day prior to the Required
Prepayment Date (it being understood that any Lender which does not notify
Company and Administrative Agent of its election to exercise such option on or
before the first Business Day prior to the Required Prepayment Date shall be
deemed to have elected, as of such date, not to exercise such option). On the
Required Prepayment Date, Company shall pay to Administrative Agent the amount
of the Waivable Mandatory Prepayment, which amount shall be applied (i) in an
amount equal to that portion of the Waivable Mandatory Prepayment payable to
those Lenders that have elected not to exercise such option, to prepay the
Tranche B Term Loans of such Lenders (which prepayment shall be applied to the
scheduled Installments of principal of the Tranche B Term Loans in

<PAGE>

accordance with Section 2.13(b)), and (ii) in an amount equal to that portion of
the Waivable Mandatory Prepayment otherwise payable to those Lenders that have
elected to exercise such option, to (x) prepay Tranche A Term Loans and New Term
Loans and/or (y) to reduce the Term Loan Commitments (which prepayment shall be
applied to the scheduled installments of principal of such Term Loans in
accordance with Section 2.13(b)).

     (d) Application of Prepayments of Loans to Base Rate Loans and Eurodollar
Rate Loans. Considering each Class of Loans being prepaid separately, any
prepayment thereof shall be applied first to Base Rate Loans of such Class to
the full extent thereof before application to Eurodollar Rate Loans of such
Class, in each case in a manner which minimizes the amount of any payments
required to be made by Company pursuant to Section 2.16(c).

     2.14. General Provisions Regarding Payments.

     (a) All payments by Company of principal, interest, fees and other
Obligations shall be made in Dollars in same day funds, without defense, setoff
or counterclaim, free of any restriction or condition, and delivered to
Administrative Agent not later than 12:00 p.m. (New York City time) on the date
due at the Administrative Agent's Principal Office for the account of Lenders;
funds received by Administrative Agent after that time on such due date shall be
deemed to have been paid by Company on the next succeeding Business Day.

     (b) All payments in respect of the principal amount of any Loan (other than
prepayments of Base Rate Loans on any day other than an Interest Payment Date)
shall include payment of accrued interest on the principal amount being repaid
or prepaid, and all such payments (and, in any event, any payments in respect of
any Loan on a date when interest is due and payable with respect to such Loan)
shall be applied to the payment of interest before application to principal.

     (c) Administrative Agent shall promptly distribute to each Lender at such
address as such Lender shall indicate in writing, such Lender's applicable Pro
Rata Share of all payments and prepayments of principal and interest due
hereunder, together with all other amounts due thereto, including, without
limitation, all fees payable with respect thereto, to the extent received by
Administrative Agent, subject to the provisions hereof and of Section 2.20 in
connection with a Defaulting Lender.

     (d) Notwithstanding the foregoing provisions hereof, if any
Conversion/Continuation Notice is withdrawn as to any Affected Lender or if any
Affected Lender makes Base Rate Loans in lieu of its Pro Rata Share of any
Eurodollar Rate Loans, Administrative Agent shall give effect thereto in
apportioning payments received thereafter, subject to the provisions hereof and
of Section 2.20 in connection with a Defaulting Lender.

     (e) Subject to the provisos set forth in the definition of "Interest
Period", whenever any payment to be made hereunder shall be stated to be due on
a day that is not a Business Day, such payment shall be made on the next
succeeding Business Day and such

<PAGE>

extension of time shall be included in the computation of the payment of
interest hereunder or of the Revolving Credit Commitment fees hereunder, as the
case may be.

     (f) Company hereby authorizes Administrative Agent to charge Company's
accounts with Administrative Agent in order to cause timely payment to be made
to Administrative Agent of all principal, interest, fees and expenses due
hereunder (subject to sufficient funds being available in its accounts for that
purpose).

     (g) Administrative Agent shall deem any payment by or on behalf of Company
hereunder that is not made in same day funds prior to 12:00 p.m. (New York City
time) to be a non-conforming payment. Any such payment shall not be deemed to
have been received by Administrative Agent until the later of (i) the time such
funds become available funds, and (ii) the applicable next Business Day.
Administrative Agent shall give prompt telephonic notice to Company and each
applicable Lender (confirmed in writing) if any payment is non-conforming.
Interest shall continue to accrue on any principal as to which a non-conforming
payment is made until such funds become available funds (but in no event less
than the period from the date of such payment to the next succeeding applicable
Business Day) at the rate determined pursuant to Section 2.8 from the date such
amount was due and payable until the date such amount is paid in full.

     2.15. Ratable Sharing. Lenders hereby agree among themselves that, except
as otherwise provided in the Collateral Documents with respect to amounts
realized from the exercise of rights with respect to Liens on the Collateral, if
any of them shall, whether by voluntary payment (other than a voluntary
prepayment of Loans made and applied in accordance with the terms hereof),
through the exercise of any right of set-off or banker's lien, by counterclaim
or cross action or by the enforcement of any right under the Credit Documents or
otherwise, or as adequate protection of a deposit treated as cash collateral
under the Bankruptcy Code, receive payment or reduction of a proportion of the
aggregate amount of principal, interest, fees and other amounts then due and
owing to such Lender hereunder or under the other Credit Documents
(collectively, the "Aggregate Amounts Due" to such Lender) which is greater than
the proportion received by any other Lender in respect of the Aggregate Amounts
Due to such other Lender, then the Lender receiving such proportionately greater
payment shall (a) notify Administrative Agent and each other Lender of the
receipt of such payment and (b) apply a portion of such payment to purchase
participations (which it shall be deemed to have purchased from each seller of a
participation simultaneously upon the receipt by such seller of its portion of
such payment) in the Aggregate Amounts Due to the other Lenders so that all such
recoveries of Aggregate Amounts Due shall be shared by all Lenders in proportion
to the Aggregate Amounts Due to them; provided, if all or part of such
proportionately greater payment received by such purchasing Lender is thereafter
recovered from such Lender upon the bankruptcy or reorganization of Company or
otherwise, those purchases shall be rescinded and the purchase prices paid for
such participations shall be returned to such purchasing Lender ratably to the
extent of such recovery, but without interest. Company expressly consents to the
foregoing arrangement and agrees that any holder of a participation so purchased
may exercise any and all rights of banker's lien, set-off or counterclaim with
respect to any and all monies owing by

<PAGE>

Company to that holder with respect thereto as fully as if that holder were owed
the amount of the participation held by that holder.

     2.16. Making or Maintaining Eurodollar Rate Loans.

     (a) Inability to Determine Applicable Interest Rate. In the event that
Administrative Agent shall have determined (which determination shall be final
and conclusive and binding upon all parties hereto), on any Interest Rate
Determination Date with respect to any Eurodollar Rate Loans, that by reason of
circumstances affecting the London interbank market adequate and fair means do
not exist for ascertaining the interest rate applicable to such Loans on the
basis provided for in the definition of Adjusted Eurodollar Rate, Administrative
Agent shall on such date give notice (by telefacsimile or by telephone confirmed
in writing) to Company and each Lender of such determination, whereupon (i) no
Loans may be made as, or converted to, Eurodollar Rate Loans until such time as
Administrative Agent notifies Company and Lenders that the circumstances giving
rise to such notice no longer exist, and (ii) any Funding Notice or
Conversion/Continuation Notice given by Company with respect to the Loans in
respect of which such determination was made shall be deemed to be rescinded by
Company.

     (b) Illegality or Impracticability of Eurodollar Rate Loans. In the event
that on any date any Lender shall have determined (which determination shall be
final and conclusive and binding upon all parties hereto but shall be made only
after consultation with Company and Administrative Agent) that the making,
maintaining or continuation of its Eurodollar Rate Loans (i) has become unlawful
as a result of compliance by such Lender in good faith with any law, treaty,
governmental rule, regulation, guideline or order (or would conflict with any
such treaty, governmental rule, regulation, guideline or order not having the
force of law even though the failure to comply therewith would not be unlawful),
or (ii) has become impracticable, as a result of contingencies occurring after
the date hereof which materially and adversely affect the London interbank
market, then, and in any such event, such Lender shall be an "Affected Lender"
and it shall on that day give notice (by telefacsimile or by telephone confirmed
in writing) to Company and Administrative Agent of such determination (which
notice Administrative Agent shall promptly transmit to each other Lender).
Thereafter (1) the obligation of the Affected Lender to make Loans as, or to
convert Loans to, Eurodollar Rate Loans shall be suspended until such notice
shall be withdrawn by the Affected Lender, (2) to the extent such determination
by the Affected Lender relates to a Eurodollar Rate Loan then being requested by
Company pursuant to a Funding Notice or a Conversion/Continuation Notice, the
Affected Lender shall make such Loan as (or continue such Loan as or convert
such Loan to, as the case may be) a Base Rate Loan, (3) the Affected Lender's
obligation to maintain its outstanding Eurodollar Rate Loans (the "Affected
Loans") shall be terminated at the earlier to occur of the expiration of the
Interest Period then in effect with respect to the Affected Loans or when
required by law, and (4) the Affected Loans shall automatically convert into
Base Rate Loans on the date of such termination. Notwithstanding the foregoing,
to the extent a determination by an Affected Lender as described above relates
to a Eurodollar Rate Loan then being requested by Company pursuant to a Funding
Notice or a Conversion/Continuation Notice, Company shall have the option,
subject to the provisions of Section 2.16(c), to rescind such Funding Notice or
Conversion/Continuation Notice

<PAGE>

as to all Lenders by giving notice (by telefacsimile or by telephone confirmed
in writing) to Administrative Agent of such rescission on the date on which the
Affected Lender gives notice of its determination as described above (which
notice of rescission Administrative Agent shall promptly transmit to each other
Lender). Except as provided in the immediately preceding sentence, nothing in
this Section 2.16(b) shall affect the obligation of any Lender other than an
Affected Lender to make or maintain Loans as, or to convert Loans to, Eurodollar
Rate Loans in accordance with the terms hereof.

     (c) Compensation for Breakage or Non-Commencement of Interest Periods.
Company shall compensate each Lender, upon written request by such Lender (which
request shall set forth the basis for requesting such amounts), for all
reasonable losses, expenses and liabilities (including any interest paid by such
Lender to lenders of funds borrowed by it to make or carry its Eurodollar Rate
Loans and any loss, expense or liability sustained by such Lender in connection
with the liquidation or re-employment of such funds but excluding loss of
anticipated profits) which such Lender may sustain: (i) if for any reason (other
than a default by such Lender) a borrowing of any Eurodollar Rate Loan does not
occur on a date specified therefor in a Funding Notice or a telephonic request
for borrowing, or a conversion to or continuation of any Eurodollar Rate Loan
does not occur on a date specified therefor in a Conversion/Continuation Notice
or a telephonic request for conversion or continuation; (ii) if any prepayment
or other principal payment or any conversion of any of its Eurodollar Rate Loans
occurs on a date prior to the last day of an Interest Period applicable to that
Loan; (iii) if any prepayment of any of its Eurodollar Rate Loans is not made on
any date specified in a notice of prepayment given by Company; or (iv) as a
consequence of any other default by Company in the repayment of its Eurodollar
Rate Loans when required by the terms hereof.

     (d) Booking of Eurodollar Rate Loans. Any Lender may make, carry or
transfer Eurodollar Rate Loans at, to, or for the account of any of its branch
offices or the office of an Affiliate of such Lender.

     (e) Assumptions Concerning Funding of Eurodollar Rate Loans. Calculation of
all amounts payable to a Lender under this Section 2.16 and under Section 2.17
shall be made as though such Lender had actually funded each of its relevant
Eurodollar Rate Loans through the purchase of a Eurodollar deposit bearing
interest at the rate obtained pursuant to clause (i) of the definition of
Adjusted Eurodollar Rate in an amount equal to the amount of such Eurodollar
Rate Loan and having a maturity comparable to the relevant Interest Period and
through the transfer of such Eurodollar deposit from an offshore office of such
Lender to a domestic office of such Lender in the United States of America;
provided, however, each Lender may fund each of its Eurodollar Rate Loans in any
manner it sees fit and the foregoing assumptions shall be utilized only for the
purposes of calculating amounts payable under this Section 2.16 and under
Section 2.17.

     2.17. Increased Costs; Capital Adequacy.

     (a) Compensation For Increased Costs and Taxes. Subject to the provisions
of

<PAGE>

Section 2.18 (which shall be controlling with respect to the matters covered
thereby), in the event that any Lender shall determine (which determination
shall, absent manifest error, be final and conclusive and binding upon all
parties hereto) that any law, treaty or governmental rule, regulation or order,
or any change therein or in the interpretation, administration or application
thereof (including the introduction of any new law, treaty or governmental rule,
regulation or order), or any determination of a court or governmental authority,
in each case that becomes effective after the date hereof, or, if later, after
the date such Lender accepts an assignment under Section 10.6, or compliance by
such Lender with any guideline, request or directive issued or made after the
date hereof or, if later, after the date such Lender accepts an assignment under
Section 10.6, by any central bank or other governmental or quasi-governmental
authority (whether or not having the force of law): (i) subjects such Lender (or
its applicable lending office) to any additional Tax (other than any Tax on the
overall net income of such Lender) with respect to this Agreement or any of its
obligations hereunder or any payments to such Lender (or its applicable lending
office) of principal, interest, fees or any other amount payable hereunder; (ii)
imposes, modifies or holds applicable any reserve (including any marginal,
emergency, supplemental, special or other reserve), special deposit, compulsory
loan, FDIC insurance or similar requirement against assets held by, or deposits
or other liabilities in or for the account of, or advances or loans by, or other
credit extended by, or any other acquisition of funds by, any office of such
Lender (other than any such reserve or other requirements with respect to
Eurodollar Rate Loans that are reflected in the definition of Adjusted
Eurodollar Rate); or (iii) imposes any other condition (other than with respect
to a Tax matter) on or affecting such Lender (or its applicable lending office)
or its obligations hereunder or the London interbank market; and the result of
any of the foregoing is to increase the cost to such Lender of agreeing to make,
making or maintaining Eurodollar Rate Loans hereunder or to reduce any amount
received or receivable by such Lender (or its applicable lending office) with
respect thereto; then, in any such case, Company shall promptly pay to such
Lender, upon receipt of the statement referred to in the next sentence, such
additional amount or amounts (in the form of an increased rate of, or a
different method of calculating, interest or otherwise as such Lender in its
sole discretion shall determine) as may be necessary to compensate such Lender
for any such increased cost or reduction in amounts received or receivable
hereunder. Such Lender shall deliver to Company (with a copy to Administrative
Agent) a written statement, setting forth in reasonable detail the basis for
calculating the additional amounts owed to such Lender under this Section
2.17(a), which statement shall be conclusive and binding upon all parties hereto
absent manifest error.

     (b) Capital Adequacy Adjustment. In the event that any Lender shall have
determined that the adoption, effectiveness, phase-in or applicability after the
Closing Date or, if later, after the date such Lender accepts an assignment
under Section 10.6, of any law, rule or regulation (or any provision thereof)
regarding capital adequacy, or any change therein or in the interpretation or
administration thereof by any Governmental Authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by any Lender (or its applicable lending office) with any guideline, request or
directive which becomes applicable after the Closing Date or, if later, after
the date such Lender accepts an assignment under Section 10.6, regarding capital
adequacy (whether or not having the force of law) of any such Governmental
Authority, central bank or comparable agency, has or would have

<PAGE>

the effect of reducing the rate of return on the capital of such Lender or any
corporation controlling such Lender as a consequence of, or with reference to,
such Lender's Loans or Revolving Credit Commitments or other obligations
hereunder with respect to the Loans to a level below that which such Lender or
such controlling corporation could have achieved but for such adoption,
effectiveness, phase-in, applicability, change or compliance (taking into
consideration the policies of such Lender or such controlling corporation with
regard to capital adequacy), then from time to time, within five Business Days
after receipt by Company from such Lender of the statement referred to in the
next sentence, Company shall pay to such Lender such additional amount or
amounts as will compensate such Lender or such controlling corporation on an
after-tax basis for such reduction. Such Lender shall deliver to Company (with a
copy to Administrative Agent) a written statement, setting forth in reasonable
detail the basis for calculating the additional amounts owed to Lender under
this Section 2.17(b), which statement shall be conclusive and binding upon all
parties hereto absent manifest error.

     (c) Limitation on Retroactive Effect. Failure or delay on the part of any
Lender to demand compensation pursuant to this Section 2.17 shall not constitute
a waiver of such Lender's right to demand such compensation; provided that
Company shall not be required to compensate a Lender pursuant to this Section
2.17 for any increased costs or reductions incurred more than 180 days prior to
the date that such Lender notifies Company of the change giving rise to such
increased costs or reductions and of such Lender's intention to claim
compensation therefor; provided further that, if the change giving rise to such
increased costs or reductions is retroactive, then the 180-day period referred
to above shall be extended to include the period of retroactive effect thereof.

     2.18. Taxes; Withholding, etc.

     (a) Payments to Be Free and Clear. All sums payable by any Credit Party
hereunder and under the other Credit Documents shall (except to the extent
required by law) be paid free and clear of, and without any deduction or
withholding on account of, any Tax (other than a Tax on the overall net income
of any Lender) imposed, levied, collected, withheld or assessed by or within the
United States of America or any political subdivision in or of the United States
of America or any other jurisdiction from which a payment is made by or on
behalf of any Credit Party or by any federation or organization of which the
United States of America or any such jurisdiction is a member at the time of
payment.

     (b) Withholding of Taxes. If any Credit Party or any other Person is
required by law to make any deduction or withholding on account of any such Tax
from any sum paid or payable by any Credit Party to Administrative Agent or any
Lender under any of the Credit Documents: (i) Company shall notify
Administrative Agent of any such requirement or any change in any such
requirement as soon as Company becomes aware of it; (ii) Company shall pay any
such Tax before the date on which penalties attach thereto, such payment to be
made (if the liability to pay is imposed on any Credit Party) for its own
account or (if that liability is imposed on Administrative Agent or such Lender,
as the case may be) on behalf of and in the name of Administrative Agent or such
Lender; (iii) the sum payable by such Credit Party in respect of

<PAGE>

which the relevant deduction, withholding or payment is required shall be
increased to the extent necessary to ensure that, after the making of that
deduction, withholding or payment, Administrative Agent or such Lender, as the
case may be, receives on the due date a net sum equal to what it would have
received had no such deduction, withholding or payment been required or made;
and (iv) within thirty (30) days after paying any sum from which it is required
by law to make any deduction or withholding, and within thirty (30) days after
the due date of payment of any Tax which it is required by clause (ii) above to
pay, Company shall deliver to Administrative Agent evidence satisfactory to the
other affected parties of such deduction, withholding or payment and of the
remittance thereof to the relevant taxing or other authority; provided, no such
additional amount shall be required to be paid to any Lender under clause (iii)
above except to the extent that any change after the date hereof (in the case of
each Lender listed on the signature pages hereof on the Closing Date) or after
the effective date of the Assignment Agreement or Joinder Agreement pursuant to
which such Lender became a Lender (in the case of each other Lender) in any such
requirement for a deduction, withholding or payment as is mentioned therein
shall result in an increase in the rate of such deduction, withholding or
payment from that in effect at the date hereof or at the date of such Assignment
Agreement or Joinder Agreement, as the case may be, in respect of payments to
such Lender.

     (c) Evidence of Exemption From U.S. Withholding Tax. Each Lender that is
not a United States Person (as such term is defined in Section 7701(a)(30) of
the Internal Revenue Code) for U.S. federal income tax purposes (a "Non-US
Lender") shall deliver to Administrative Agent for transmission to Company, on
or prior to the Closing Date (in the case of each Lender listed on the signature
pages hereof on the Closing Date) or on or prior to the date of the Assignment
Agreement or Joinder Agreement pursuant to which it becomes a Lender (in the
case of each other Lender), and at such other times as may be necessary in the
determination of Company or Administrative Agent (each in the reasonable
exercise of its discretion), (i) two original copies of Internal Revenue Service
Form W-8BEN or W-8ECI (or any successor forms), properly completed and duly
executed by such Lender, and such other documentation required under the
Internal Revenue Code and reasonably requested by Company to establish that such
Lender is not subject to deduction or withholding of United States federal
income tax with respect to any payments to such Lender of principal, interest,
fees or other amounts payable under any of the Credit Documents, or (ii) if such
Lender is not a "bank" or other Person described in Section 881(c)(3) of the
Internal Revenue Code and cannot deliver either Internal Revenue Service Form
W-8BEN or W-8ECI pursuant to clause (i) above, a Certificate re Non-Bank Status
together with two original copies of Internal Revenue Service Form W-8 (or any
successor form), properly completed and duly executed by such Lender, and such
other documentation required under the Internal Revenue Code and reasonably
requested by Company to establish that such Lender is not subject to deduction
or withholding of United States federal income tax with respect to any payments
to such Lender of interest payable under any of the Credit Documents. Each
Lender required to deliver any forms, certificates or other evidence with
respect to United States federal income tax withholding matters pursuant to this
Section 2.18(c) hereby agrees, from time to time after the initial delivery by
such Lender of such forms, certificates or other evidence, whenever a lapse in
time or change in circumstances renders such forms, certificates or other
evidence obsolete or inaccurate in any material respect, that such Lender shall
promptly deliver to

<PAGE>

Administrative Agent for transmission to Company two new original copies of
Internal Revenue Service Form W-8BEN or W-8ECI , or a Certificate re Non-Bank
Status and two original copies of Internal Revenue Service Form W-8, as the case
may be, properly completed and duly executed by such Lender, and such other
documentation required under the Internal Revenue Code and reasonably requested
by Company to confirm or establish that such Lender is not subject to deduction
or withholding of United States federal income tax with respect to payments to
such Lender under the Credit Documents, or notify Administrative Agent and
Company of its inability to deliver any such forms, certificates or other
evidence. Company shall not be required to pay any additional amount to any
Non-US Lender under Section 2.18(b)(iii) if such Lender shall have failed (1) to
deliver the forms, certificates or other evidence referred to in the second
sentence of this Section 2.18(c), or (2) to notify Administrative Agent and
Company of its inability to deliver any such forms, certificates or other
evidence, as the case may be; provided, if such Lender shall have satisfied the
requirements of the first sentence of this Section 2.18(c) on the Closing Date
or on the date of the Assignment Agreement or Joinder Agreement pursuant to
which it became a Lender, as applicable, nothing in this last sentence of
Section 2.18(c) shall relieve Company of its obligation to pay any additional
amounts pursuant to Section 2.17(a) in the event that, as a result of any change
in any applicable law, treaty or governmental rule, regulation or order, or any
change in the interpretation, administration or application thereof, such Lender
is no longer properly entitled to deliver forms, certificates or other evidence
at a subsequent date establishing the fact that such Lender is not subject to
withholding as described herein.

     (d) Reimbursement of Savings. If a Credit Party pays any additional amount
under this Section 2.18 and, as a result, any Lender, together with
Administrative Agent, subsequently, in their sole discretion and based on their
own interpretation of any relevant laws (but acting in good faith) receive or
are granted a final and non-appealable credit against or deduction from or in
respect of any tax payable by such Lender, or obtain any other final and
non-appealable relief in respect of any tax, which in the opinion of such Lender
and Administrative Agent, acting in good faith, is both reasonably identifiable
and quantifiable by them without requiring any Lender, Administrative Agent or
their professional advisors to expend a material amount of time or incur a
material cost in so identifying or quantifying (any of the foregoing, to the
extent so reasonably identifiable and quantifiable, being referred to as a
"Saving"), such Lender shall, to the extent that it can do so without prejudice
to the retention of the Saving, reimburse such Credit Party promptly after such
identification and quantification with the amount of such Saving; provided,
however, that any such Saving shall be reduced by any costs incurred by such
Lender or Administrative Agent in obtaining such Saving; provided, further, that
nothing in this Section 2.18(d) shall require any Lender to disclose to any
Person any information regarding its tax affairs or to arrange its tax and other
affairs in any particular manner.

     2.19. Obligation to Mitigate. Each Lender agrees that, as promptly as
practicable after the officer of such Lender responsible for administering its
Loans, becomes aware of the occurrence of an event or the existence of a
condition that would cause such Lender to become an Affected Lender or that
would entitle such Lender to receive payments under Section 2.16, 2.17 or 2.18,
it will, to the extent not inconsistent with the internal policies of such
Lender and any applicable legal or regulatory restrictions, use reasonable
efforts (a) to make, issue, fund or

<PAGE>

maintain its Credit Extensions, including any Affected Loans, through another
office of such Lender, or (b) take such other measures as such Lender may deem
reasonable, if as a result thereof the circumstances which would cause such
Lender to be an Affected Lender would cease to exist or the additional amounts
which would otherwise be required to be paid to such Lender pursuant to Section
2.16, 2.17 or 2.18 would be materially reduced and if, as determined by such
Lender in its sole discretion, the making, issuing, funding or maintaining of
such Revolving Credit Commitments or Loans through such other office or in
accordance with such other measures, as the case may be, would not otherwise
adversely affect such Revolving Credit Commitments or Loans or the interests of
such Lender; provided, such Lender will not be obligated to utilize such other
office pursuant to this Section 2.19 unless Company agrees to pay all
incremental expenses incurred by such Lender as a result of utilizing such other
office as described in clause (i) above. A certificate as to the amount of any
such expenses payable by Company pursuant to this Section 2.19 (setting forth in
reasonable detail the basis for requesting such amount) submitted by such Lender
to Company (with a copy to Administrative Agent) shall be conclusive absent
manifest error.

     2.20. Defaulting Lenders. Anything contained herein to the contrary
notwithstanding, in the event that any Lender, at the direction or request of
any regulatory agency or authority, defaults (a "Defaulting Lender") in its
obligation to fund (a "Funding Default") any Loan (in each case, a "Defaulted
Loan"), then (a) during any Default Period with respect to such Defaulting
Lender, such Defaulting Lender shall be deemed not to be a "Lender" for purposes
of voting on any matters (including the granting of any consents or waivers)
with respect to any of the Credit Documents; (b) to the extent permitted by
applicable law, until such time as the Default Excess with respect to such
Defaulting Lender shall have been reduced to zero, (i) any voluntary prepayment
of the Loans shall, if Company so directs at the time of making such voluntary
prepayment, be applied to the Loans of other Lenders as if such Defaulting
Lender had no Loans outstanding and the Revolving Credit Exposure, Tranche A
Term Loan Exposure, Tranche B Term Loan Exposure, New Revolving Loan Exposure
and New Term Loan Exposure of such Defaulting Lender were zero, and (ii) any
mandatory prepayment of the Loans shall, if Company so directs at the time of
making such mandatory prepayment, be applied to the Loans of other Lenders (but
not to the Loans of such Defaulting Lender) as if such Defaulting Lender had no
Loans outstanding, it being understood and agreed that Company shall be entitled
to retain any portion of any mandatory prepayment of the Loans that is not paid
to such Defaulting Lender solely as a result of the operation of the provisions
of this clause (b); (c) such Defaulting Lender's Revolving Credit Commitment,
Tranche A Term Loan Commitment, New Revolving Credit Commitment and New Term
Loan Commitment, and outstanding Loans shall be excluded for purposes of
calculating the Commitment Fee payable to Lenders in respect of any day during
any Default Period with respect to such Defaulting Lender, and such Defaulting
Lender shall not be entitled to receive any Commitment Fee pursuant to Section
2.9 with respect to such Defaulting Lender's Revolving Credit Commitment and
Tranche A Term Loan Commitment in respect of any Default Period with respect to
such Defaulting Lender; and (d) the Total Utilization of Commitments as at any
date of determination shall be calculated as if such Defaulting Lender had
funded all Defaulted Loans of such Defaulting Lender. No Commitment of any
Lender shall be increased or otherwise affected, and, except as otherwise
expressly provided in this Section 2.20,

<PAGE>

performance by Company of its obligations hereunder and the other Credit
Documents shall not be excused or otherwise modified as a result of any Funding
Default or the operation of this Section 2.20. The rights and remedies against a
Defaulting Lender under this Section 2.20 are in addition to other rights and
remedies which Company may have against any such Lender with respect to any
Funding Default and which Administrative Agent or any Lender may have against
such Defaulting Lender with respect to any Funding Default.

     2.21. Removal or Replacement of a Lender. Anything contained herein to the
contrary notwithstanding, in the event that: (a) any Lender (an "Increased-Cost
Lender") shall give notice to Company that such Lender is an Affected Lender or
that such Lender is entitled to receive payments under Section 2.16, 2.17 or
2.18, the circumstances which have caused such Lender to be an Affected Lender
or which entitle such Lender to receive such payments shall remain in effect,
and such Lender shall fail to withdraw such notice within five Business Days
after Company's request for such withdrawal; or (b) any Lender shall become a
Defaulting Lender, the Default Period for such Defaulting Lender shall remain in
effect, and such Defaulting Lender shall fail to cure the default as a result of
which it has become a Defaulting Lender within five Business Days after
Company's request that it cure such default; then, with respect to each such
Increased-Cost Lender or Defaulting Lender (the "Terminated Lender"), Company
may, by giving written notice to Administrative Agent and any Terminated Lender
of its election to do so, elect to cause such Terminated Lender (and such
Terminated Lender hereby irrevocably agrees) to assign its outstanding Loans and
its Revolving Credit Commitments, if any, in full to one or more Eligible
Assignees (each a "Replacement Lender") in accordance with the provisions of
Section 10.6 and Terminated Lender shall pay any fees payable thereunder in
connection with such assignment; provided, (1) on the date of such assignment,
the Replacement Lender shall pay to Terminated Lender an amount equal to the sum
of (A) an amount equal to the principal of, and all accrued interest on, all
outstanding Loans of the Terminated Lender and (B) an amount equal to all
accrued, but theretofore unpaid fees owing to such Terminated Lender pursuant to
Section 2.9 and (2) on the date of such assignment, Company shall pay any
amounts payable to such Terminated Lender pursuant to Section 2.16(c), 2.17 or
2.18 or otherwise as if it were a prepayment. Upon the payment of all amounts
owing to any Terminated Lender and the termination of such Terminated Lender's
Revolving Credit Commitments, if any, such Terminated Lender shall no longer
constitute a "Lender" for purposes hereof; provided, any rights of such
Terminated Lender to indemnification hereunder shall survive as to such
Terminated Lender.

     2.22. Increased Amounts. Company may by written notice to Administrative
Agent elect to either (A) increase the Revolving Credit Commitments (any such
increase, "New Revolving Credit Commitments") and/or (B) establish a new term
loan facility (the "New Term Loan Commitments"), by an amount not in excess of
$1,000,000,000 in the aggregate and not less than $50,000,000 individually and
integral multiples of $50,000,000 in excess of that amount. Each such notice
shall specify (a) the date (each, an "Increased Amount Date") on which Company
proposes that the New Revolving Credit Commitments or that the New Term Loan
Commitments, as applicable, shall be effective and that revolving loans made
pursuant to the New Revolving Credit Commitments (collectively, "New Revolving
Loans") and/or Term Loans made pursuant to the New Term Loan Commitments
(collectively, "New Term Loans") shall be

<PAGE>

made, as applicable, which shall be made not less than 10 Business Days after
the date on which such notice is delivered to Administrative Agent and (b) the
identity of each Lender or other Person that meets the requirements of an
Eligible Assignee (each, a "New Revolving Lender" or a "New Term Loan Lender",
as applicable) to whom Company proposes any portion of such New Revolving Credit
Commitments or New Term Loan Commitments, as applicable, be allocated and the
amounts of such allocations; provided any Lender approached by Company may elect
or decline, in its sole discretion, to provide a New Revolving Credit Commitment
or a New Term Loan Commitment. Any New Revolving Loans or New Term Loans made
shall be deemed to be a separate series ("Series") of such New Revolving Loans
or New Term Loans, as applicable, for all purposes of this Agreement.

     Each Series of New Revolving Loan Commitments or New Term Loan Commitments
shall become effective and any Series of New Revolving Loans or New Term Loans
shall be made, as applicable, as of such Increased Amount Date, provided:

     (1)  no Default or Event of Default shall exist on such Increased Amount
          Date before or after giving effect to such Series of New Revolving
          Loan Commitments or New Term Loan Commitments, as applicable;

     (2)  both before and after giving effect to the making of such Series of
          New Revolving Loans or New Term Loans each of the conditions set forth
          in Section 3.2 shall be satisfied;

     (3)  such Series of New Revolving Loan Commitments and/or New Term Loan
          Commitments, as applicable, shall be effected pursuant to one or more
          joinder agreements, in each case in form and substance reasonably
          satisfactory to Administrative Agent, and executed and delivered to
          Company and Administrative Agent and recorded in the Register (each, a
          "Joinder Agreement"), each of which shall be subject to the
          requirements of Section 2.18(c);

     (4)  Company shall make any payments required pursuant to Section 2.16(c);

     (5)  Company shall deliver or cause to be delivered any legal opinions or
          other documents reasonably requested by Administrative Agent in
          connection with any such transaction;

     (6)  If the maturity date for any Series of New Revolving Loans or New Term
          Loans is after June 30, 2007, such maturity date will be accelerated
          to June 30, 2007 if the notice specified in Section 5.1(k)(ii) has not
          been received by the Administrative Agent prior to June 30, 2007;

     (7)  The first aggregate $500,000,000 of all Series of New Revolving Credit
          Commitments and/or New Term Loans (the "First Increment") shall be
          available only if (i) Tranche A Term Loans equal to $387,500,000 have
          been made, (ii) the

<PAGE>

          terms of each Series of the First Increment, as specified in the
          applicable Joinder Agreement or agreements, are not materially less
          favorable to Company than the terms of Tranche B Term Loan, (iii) no
          scheduled repayment or amortization of any Series of the First
          Increment occurs earlier than for Tranche A Term Loans, and (iv) the
          interest rate applicable for each Series of the First Increment is no
          greater than the interest rate for Tranche B Term Loans plus 0.25% per
          annum; and

     (8)  The second aggregate $500,000,000 of such increased commitments (the
          "Second Increment") shall be available only if (i) the weighted
          average life of each Series of the Second Increment (which shall be a
          term facility) is longer than the weighted average life collectively
          of Tranche A Term Loan, Tranche B Term Loan and the Revolving Loans
          (not including any New Revolving Loans or New Term Loans), (ii) the
          terms of each Series of the Second Increment, as specified in the
          applicable Joinder Agreement or agreements, are not materially less
          favorable to Company than the terms of Tranche B Term Loan, (iii) the
          final maturity of each Series of the Second Increment is six months
          after the Tranche B Term Loan Maturity Date (subject to acceleration
          as specified in clause (6) above), and (iv) a corresponding
          dollar-for-dollar amount of the Revolving Loan (up to a maximum of
          $275,000,000) is converted to a Tranche A Term Loan, and the Revolving
          Credit Commitment is permanently reduced by such amount.

     On any Increased Amount Date on which any Series of New Revolving Loan
Commitments of any Series are effected, subject to the satisfaction of the
foregoing terms and conditions, (A) each of the Revolving Lenders shall assign
to each of the New Revolving Lenders of such Series, and each of the New
Revolving Lenders of such Series shall purchase from each of the Revolving
Lenders, at the principal amount thereof (together with accrued interest), such
interests in the Revolving Loans outstanding on such Increased Amount Date as
shall be necessary in order that, after giving effect to all such assignments
and purchases, such Revolving Loans will be held by Revolving Lenders and New
Revolving Lenders of such Series ratably in accordance with their Revolving
Credit Commitments after giving effect to the addition of such New Revolving
Credit Commitments of such Series and (B) each New Revolving Lender of such
Series shall become a Lender hereunder with respect to the New Revolving Credit
Commitment of such Series and all matters relating thereto.

     On any Increased Amount Date on which any Series of New Term Loan
Commitments are effective subject to the satisfaction of the foregoing terms and
conditions, (I) each New Lender of such Series shall make a New Term Loan of
such Series to Company in an amount equal to its New Term Loan Commitment of
such Series, (II) each New Term Loan of such Series shall be deemed for all
purposes, a Term Loan, and (III) each New Term Loan Lender of such Series shall
become a Lender hereunder with respect to the New Term Loan Commitments of such
Series.

     The Administrative Agent shall notify the Lenders promptly upon receipt of

<PAGE>

Company's notice of each Increased Amount Date and in respect thereof the New
Revolving Credit Commitments of each Series and the New Revolving Lenders of
such Series, or the New Term Commitments of such Series and the New Term Loan
Lenders of such Series, as applicable, and, in the case of each notice to any
Revolving Lender, the respective interests in such Revolving Lender's Revolving
Loans subject to the assignments contemplated by this subsection. The terms and
provisions of the New Revolving Credit Commitments of each Series and New
Revolving Loans of such Series and the New Term Loan Commitments of each Series
and New Term Loans of such Series shall be identical to the type of Commitment
or Loans being increased except as otherwise specified in the applicable Joinder
Agreement or Agreements, in accordance with the provisions specified in this
Section 2.22.

SECTION 3. CONDITIONS PRECEDENT

     3.1. Closing Date. The obligation of any Lender to make a Credit Extension
on the Closing Date is subject to the satisfaction, or waiver in accordance with
Section 10.5, of the following conditions on or before the Closing Date:

SECTION 4. REPRESENTATIONS AND WARRANTIES

     In order to induce Lenders to enter into this Agreement and to make each

to each Lender, on the Closing Date and on each Credit Date, that the following
statements are true and correct:

     4.1. Organization; Requisite Power and Authority; Qualification. Each of
Company and its Subsidiaries (i) is validly existing and (to the extent
applicable) in good standing under the laws of its jurisdiction of organization
as identified in Schedule 4.1 as of the Closing Date, (ii) has all requisite
power and authority to own and operate its properties, to carry on its business
as now conducted and as proposed to be conducted, to enter into the Credit
Documents to which it is a party and to carry out the transactions contemplated
thereby, and (iii) is qualified to do business and (to the extent applicable) in
good standing in every jurisdiction where its assets are located and wherever
necessary to carry out its business and operations, except in jurisdictions
where the failure to be so qualified or in good standing has not had, and could
not be reasonably expected to have, a Material Adverse Effect.

     4.2. Capital Stock and Ownership. The Capital Stock of each of Company and
its Subsidiaries has been duly authorized and validly issued and is fully paid
and non-assessable.

<PAGE>

Except as expressly provided on Schedule 4.2, as of the date hereof, there is no
existing option, warrant, call, right, commitment or other agreement to which
Company or any of its Subsidiaries is a party requiring, and there is no
membership interest or other Capital Stock of Company or any of its Subsidiaries
outstanding which upon conversion or exchange would require, the issuance by any
of Company's Subsidiaries of any additional membership interests or other
Capital Stock of any of Company's Subsidiaries or other Securities convertible
into, exchangeable for or evidencing the right to subscribe for or purchase, a
membership interest or other Capital Stock of any of Company's Subsidiaries.
Schedule 4.2 correctly sets forth the ownership interest of Company and each of
its Subsidiaries (including Unrestricted Subsidiaries) in their respective
Subsidiaries (including Unrestricted Subsidiaries) as of the Closing Date.

     4.3. Due Authorization. The execution, delivery and performance of the
Credit Documents have been duly authorized by all necessary action on the part
of each Credit Party that is a party thereto.

     4.4. No Conflict. The execution, delivery and performance by Credit Parties
of the Credit Documents to which they are parties and the consummation of the
transactions contemplated by the Credit Documents (except as otherwise
contemplated by Section 5.15) do not and will not (a) violate any provision of
any law or any governmental rule or regulation applicable to Company or any of
its Subsidiaries, any of the Organizational Documents of Company or any of its
Subsidiaries, or any order, judgment or decree of any court or other agency of
government binding on Company or any of its Subsidiaries; (b) breach or
constitute (with due notice or lapse of time or both) a default under any
Contractual Obligation of Company or any of its Subsidiaries; (c) result in or
require the creation or imposition of any Lien upon any of the properties or
assets of Company or any of its Subsidiaries (other than any Liens created under
any of the Credit Documents in favor of Administrative Agent, on behalf of
Lenders); or (d) require any approval of stockholders or any approval or consent
of any Person under any Contractual Obligation of Company or any of its
Subsidiaries, which, in either case, has not been obtained.

     4.5. Governmental Consents. The execution, delivery and performance by
Credit Parties of the Credit Documents to which they are parties and the
consummation of the transactions contemplated by the Credit Documents (except as
otherwise contemplated by Section 5.15) do not and will not require any
registration with, consent or approval of, or notice to, or other action to,
with or by, any Governmental Authority, except for filings and recordings with
respect to the Collateral to be made, or otherwise delivered to Administrative
Agent, as of the Closing Date.

     4.6. Binding Obligation. Each Credit Document has been duly executed and
delivered by each Credit Party that is a party thereto and is the legally valid
and binding obligation of such Credit Party, enforceable against such Credit
Party in accordance with its respective terms, except as may be limited by
bankruptcy, insolvency, reorganization, moratorium or similar laws relating to
or limiting creditors' rights generally or by equitable principles relating to
enforceability.

     4.7. Historical Financial Statements. The Historical Financial Statements
were

<PAGE>

prepared in conformity with GAAP and fairly present, in all material respects,
the financial position, on a consolidated basis, of the Persons described in
such financial statements as at the respective dates thereof and the results of
operations and cash flows, on a consolidated basis, of the entities described
therein for each of the periods then ended, subject, in the case of any such
unaudited financial statements, to changes resulting from audit and normal
year-end adjustments. Neither Company nor any of its Subsidiaries has any
contingent liability or liability for taxes, long-term lease or unusual forward
or long-term commitment that is not reflected in the Historical Financial
Statements or the notes thereto and which in any such case is material in
relation to the business, operations, properties, assets, condition (financial
or otherwise) or prospects of Company and any of its Subsidiaries taken as a
whole.

     4.8. Projections. On and as of the Closing Date, the Projections of Company
and its Subsidiaries delivered pursuant to Section 3.1(g)(iii) (the
"Projections") are based on good faith estimates and assumptions made by the
management of Company; provided, the Projections are not to be viewed as facts
and that actual results during the period or periods covered by the Projections
may differ from such Projections and that the differences may be material;
provided further, as of the Closing Date, management of Company believed that
the Projections were reasonable and attainable.

     4.9. No Material Adverse Change. Since December 31, 1998, no event or
change has occurred that has caused or evidences, either in any case or in the
aggregate, a Material Adverse Effect.

     4.10. No Restricted Junior Payments. Since December 31, 1998, neither
Company nor any of its Subsidiaries has directly or indirectly declared,
ordered, paid or made, or set apart any sum or property for, any Restricted
Junior Payment or agreed to do so except as permitted pursuant to Section 6.4.

     4.11. Adverse Proceedings, etc. There are no Adverse Proceedings,
individually or in the aggregate, that could reasonably be expected to have a
Material Adverse Effect. Neither Company nor any of its Subsidiaries is subject
to or in default with respect to any final judgments, writs, injunctions,
decrees, rules or regulations of any court or any federal, state, municipal or
other governmental department, commission, board, bureau, agency or
instrumentality, domestic or foreign, that, individually or in the aggregate,
could reasonably be expected to have a Material Adverse Effect.

     4.12. Payment of Taxes. Except as otherwise permitted under Section 5.3,
all material tax returns and reports of Company and its Subsidiaries required to
be filed by any of them have been timely filed or caused to be filed, and all
taxes shown on such tax returns to be due and payable and all assessments, fees
and other governmental charges upon Company and its Subsidiaries and upon their
respective properties, assets, income, businesses and franchises which are due
and payable have been paid or caused to be paid when due and payable, except
such taxes the amount, applicability or validity of which are being contested in
good faith by appropriate proceedings and with respect to which reserves or
other appropriate provisions, if any, as shall be

<PAGE>

required in conformity with GAAP shall have been made or provided therefor.
Company knows of no proposed tax assessment against Company or any of its
Subsidiaries which is not being actively contested by Company or such Subsidiary
in good faith and by appropriate proceedings; provided, such reserves or other
appropriate provisions, if any, as shall be required in conformity with GAAP
shall have been made or provided therefor.

     4.13. Properties.

     (a) Title. Each of Company and its Subsidiaries has (i) good, sufficient
and legal title to (in the case of fee interests in real property), (ii) valid
leasehold interests in (in the case of leasehold interests in real or personal
property), and (iii) good title to (in the case of all other personal property),
all of their respective properties and assets reflected in their respective
Historical Financial Statements referred to in Section 4.7 and in the most
recent financial statements delivered pursuant to Section 5.1, in each case
except for assets disposed of since the date of such financial statements in the
ordinary course of business, as described in Schedule 4.13 or as otherwise
permitted under Section 6.8. Except as permitted by this Agreement, all such
properties and assets are free and clear of Liens.

     (b) Real Estate. As of the Closing Date, Schedule 4.13 contains a true,
accurate and complete list of (i) all Material Real Estate Assets, and (ii) all
leases, subleases or assignments of leases (together with all amendments,
modifications, supplements, renewals or extensions of any thereof) affecting
each Material Real Estate Asset of any Credit Party, regardless of whether such
Credit Party is the landlord or tenant (whether directly or as an assignee or
successor in interest) under such lease, sublease or assignment. Except as
specified in Schedule 4.13 as of the Closing Date, each agreement listed in
clause (ii) of the immediately preceding sentence is in full force and effect
and Company does not have knowledge of any default that has occurred and is
continuing thereunder, and each such agreement constitutes the legally valid and
binding obligation of each applicable Credit Party, enforceable against such
Credit Party in accordance with its terms, except as enforcement may be limited
by bankruptcy, insolvency, reorganization, moratorium or similar laws relating
to or limiting creditors' rights generally or by equitable principles.

     4.14. Collateral.

     (a) Attachment and Perfection. The execution and delivery of the Collateral
Documents by Credit Parties, together with the actions taken on or prior to the
date hereof pursuant to Section 3.1(e), are effective to create in favor of
Administrative Agent, on behalf of Lenders, as security for the respective
Obligations, a valid and perfected Lien on all of the Collateral (and First
Priority Lien on the Pledged Securities), including, without limitation, a valid
and perfected Lien on all Telecommunications Assets constructed, acquired or
improved with Loan proceeds, and all filings and other actions necessary or
desirable to perfect and maintain the perfection, and First Priority status of
such Liens, as applicable, have been duly made or taken and remain in full force
and effect, other than (i) the filing of any UCC financing statements and other
documents delivered to Administrative Agent for filing or recording (but not yet
filed or

<PAGE>

recorded), (ii) the actions required under federal law to register and record
interests in intellectual property and (iii) the periodic filing of UCC
continuation statements in respect of UCC financing statements filed by or on
behalf of Administrative Agent.

either (i) the pledge or grant by any Credit Party of the Liens purported to be
created in favor of Administrative Agent pursuant to any of the Collateral
Documents or (ii) the exercise by Administrative Agent of any rights or remedies
in respect of any Collateral (whether specifically granted or created pursuant
to any of the Collateral Documents or created or provided for by applicable
law), except (A) for filings or recordings contemplated by Section 3.1(e), (B)
as may be required, in connection with the disposition of any Investment
Property, by laws generally affecting the offering and sale of Securities and

securities or assets of regulated entities in connection with the exercise of

in effect covering all or any part of the Collateral is on file in any filing or
recording office.

     (d) Disclosure. All information supplied to Administrative Agent by or on
behalf of any Credit Party with respect to any of the Collateral (in each case
taken as a whole with respect to any particular Collateral) is accurate and
complete in all material respects.

     4.15. Environmental Matters. Neither Company nor any of its Subsidiaries
nor any of their respective Facilities currently owned, or to the best knowledge
of Company and its Subsidiaries, formerly owned, or operations are subject to
any outstanding written order, consent decree or settlement agreement with any
Person relating to any Environmental Law, any Environmental Claim, or any
Hazardous Materials Activity that, individually or in the aggregate, could
reasonably be expected to have a Material Adverse Effect. Neither Company nor
any of its Subsidiaries has received any letter or request for information under
Section 104 of the Comprehensive Environmental Response, Compensation, and
Liability Act (42 U.S.C. ss. 9604) or any comparable state law. There are, and
to the knowledge of each of Company and its Subsidiaries, have been no
conditions, occurrences, or Hazardous Materials Activities which could
reasonably be expected to form the basis of an Environmental Claim against
Company or any of its Subsidiaries that, individually or in the aggregate, could
reasonably be expected to have a Material Adverse Effect. Neither Company nor
any of its Subsidiaries nor, to any Credit Party's knowledge, any predecessor of
Company or any of its Subsidiaries has filed any notice under any Environmental
Law of past or present treatment of Hazardous Materials at any Facility, and
none of the operations of Company or any of its Subsidiaries involves the
generation, transportation, treatment, storage or disposal of hazardous waste,
as defined under 40 C.F.R. Parts 260-270 or any state equivalent, except in the
ordinary course of business and in compliance with law.

<PAGE>

Compliance with all current or reasonably foreseeable future requirements
pursuant to or under Environmental Laws could not be reasonably expected to
have, individually or in the aggregate, a Material Adverse Effect. No event or
condition has occurred or is occurring with respect to Company or any of its
Subsidiaries relating to any Environmental Law, any Release of Hazardous
Materials, or any Hazardous Materials Activity which individually or in the
aggregate has had, or could reasonably be expected to have, a Material Adverse
Effect.

     4.16. No Defaults. Neither Company nor any of its Subsidiaries is in
default in the performance, observance or fulfillment of any of the obligations,
covenants or conditions contained in any of its Contractual Obligations, and no
condition exists which, with the giving of notice or the lapse of time or both,
could constitute such a default, except where the consequences, direct or
indirect, of such default or defaults, if any, could not reasonably be expected
to have a Material Adverse Effect.

     4.17. Material Contracts. Schedule 4.17 contains a true, correct and
complete list of all the Material Contracts in effect on the Closing Date, and
except as described thereon, all such Material Contracts are in full force and
effect to the extent not terminated in accordance with their respective terms,
and no defaults exist thereunder as of the Closing Date.

     4.18. Governmental Regulation. Neither Company nor any of its Subsidiaries
(except for those listed on Schedule 1.1 hereto) is subject to regulation under
the Public Utility Holding Company Act of 1935, the Federal Power Act or the
Investment Company Act of 1940 or under any other federal or state statute or
regulation which may limit its ability to incur Indebtedness or which may
otherwise render all or any portion of the Obligations unenforceable. Neither
Company nor any of its Subsidiaries is a "registered investment company" or
company "controlled" by a "registered investment company" or a "principal
underwriter" of a "registered investment company" as such terms are defined in
the Investment Company Act of 1940.

     4.19. Margin Stock. Neither Company nor any of its Subsidiaries is engaged
principally, or as one of its important activities, in the business of extending
credit for the purpose of purchasing or carrying any Margin Stock. No part of
the proceeds of the Loans will be used, whether directly or indirectly, and
whether immediately, incidentally or ultimately, to purchase or carry Margin
Stock and the making of the Loans does not and will not violate Regulation T, U
or X of the Board of Governors of the Federal Reserve System .

     4.20. Employee Matters. Neither Company nor any of its Subsidiaries is
engaged in any unfair labor practice that could reasonably be expected to have a
Material Adverse Effect. There is (a) no unfair labor practice complaint pending
against Company or any of its Subsidiaries, or to the best knowledge of Company
and its Subsidiaries, threatened against any of them before the National Labor
Relations Board and no grievance or arbitration proceeding arising out of or
under any collective bargaining agreement that is so pending against Company or
any of its Subsidiaries or to the best knowledge of Company and its
Subsidiaries, threatened against any of them that could reasonably be expected
to result in a Material Adverse Effect, (b) no strike or work stoppage in
existence or threatened involving Company or any of its Subsidiaries that could

<PAGE>

reasonably be expected to have a Material Adverse Effect, and (c) to the best
knowledge of Company and its Subsidiaries, no union representation question
existing with respect to the employees of Company or any of its Subsidiaries
and, to the best knowledge of Company and its Subsidiaries, no union
organization activity that is taking place, except (with respect to any matter
specified in clause (a), (b) or (c) above, either individually or in the
aggregate) such as is not reasonably likely to have a Material Adverse Effect.

     4.21. Employee Benefit Plans. Company and each of its Subsidiaries are in
compliance with all applicable provisions and requirements of ERISA and the
Internal Revenue Code and the regulations and published interpretations
thereunder with respect to each Company Employee Benefit Plan, and have
performed all their obligations under each such Company Employee Benefit Plan,
except where non-compliance could not reasonably be expected to result in a
Material Adverse Effect. Each Company Employee Benefit Plan which is intended to
qualify under Section 401(a) of the Internal Revenue Code is so qualified. No
liability to the PBGC (other than required premium payments), the Internal
Revenue Service, any Company Employee Benefit Plan or any trust established
under Title IV of ERISA has been or is expected to be incurred by Company, any
of its Subsidiaries or any of their ERISA Affiliates, except where such
liability could not reasonably be expected to result in a Material Adverse
Effect. No ERISA Event has occurred or is reasonably expected to occur, except
where it is not reasonably likely to result in a Material Adverse Effect. Except
to the extent required under Section 4980B of the Internal Revenue Code or
similar state laws, and except where the liabilities for such benefits are not
reasonably likely to result in a Material Adverse Effect, no Company Employee
Benefit Plan provides health or welfare benefits (through the purchase of
insurance or otherwise) for any retired or former employee of Company or any of
its Subsidiaries. As of the most recent valuation date for any Pension Plan, the
amount of unfunded benefit liabilities (as defined in Section 4001(a)(18) of
ERISA), individually or in the aggregate for all Pension Plans (excluding for
purposes of such computation any Pension Plans with respect to which assets
exceed benefit liabilities), does not exceed $5,000,000. As of the most recent
valuation date for each Multiemployer Plan for which the actuarial report is
available, the potential liability of Company, its Subsidiaries and their
respective ERISA Affiliates for a complete withdrawal from such Multiemployer
Plan (within the meaning of Section 4203 of ERISA), when aggregated with such
potential liability for a complete withdrawal from all Multiemployer Plans,
based on information available pursuant to Section 4221(e) of ERISA, does not
exceed $5,000,000. Company and each of its Subsidiaries have complied with the
requirements of Section 515 of ERISA with respect to each Multiemployer Plan and
are not in material "default" (as defined in Section 4219(c)(5) of ERISA) with
respect to payments to a Multiemployer Plan.

     4.22. Certain Fees. No broker's or finder's fee or commission will be
payable with respect hereto or any of the transactions contemplated hereby.

     4.23. Solvency. Each Credit Party is and, upon the incurrence of any
Obligation by such Credit Party on any date on which this representation and
warranty is made, will be, Solvent.

     4.24. Year 2000 Issues. Each system of Company and its Subsidiaries,
including, without

<PAGE>

limitation, software, hardware, databases or embedded control systems, that
constitutes any part of, or is used in connection with the use, operation or
enjoyment of, any tangible or intangible assets or property of Company or any of
its Subsidiaries, whether used by Company or any of its Subsidiaries
individually or forming part of the procedure or services sold or furnished to
others (collectively, a "System"), (a) has been modified to the extent necessary
to enable it to operate from and after January 1, 2000, without error arising
from the creation, recognition, acceptance, calculation, display, storage,
retrieval, accessing, comparison, sorting, manipulation, processing or other use
of dates or date-based, date-dependent or date-related data, including but not
limited to century recognition, day-of-the-week recognition, leap years, date
values and interfaces of data functionalities and (b) will not be adversely
affected by the advent of the year 2000, the advent of the twenty-first century
or the transition from the twentieth century through the year 2000 and into the
twenty-first century (collectively, items (a) and (b) are referred to herein as
"Year 2000 Compliant") except, in either case, as would not reasonably be
expected to have a Material Adverse Effect. Except as would not reasonably be
expected to have a Material Adverse Effect, neither Company nor any of its
Subsidiaries has received notice, or otherwise based on third party information
available to Company or any of its Subsidiaries, has any reason to believe, that
any System receives data from or communicates with any component or system
external to itself (whether or not such component or system is the Company's or
any of its Subsidiaries') that is not itself expected to be Year 2000 Compliant
prior to December 31, 1999. Neither Company nor any Subsidiary has any reason to
believe that it may incur material expenses arising from or relating to the
failure of any of its Systems as a result of not being Year 2000 Compliant and
Company and its Subsidiaries have requested and received assurances from each
third party whose systems failure would reasonably be expected to have a
Material Adverse Effect that such systems are Year 2000 Compliant.

     4.25. Compliance with Statutes, etc. Each of Company and its Subsidiaries
is in compliance with all applicable statutes, regulations and orders of, and
all applicable restrictions imposed by, all Governmental Authorities, in respect
of the conduct of its business and the ownership of its property (including
compliance with all applicable Environmental Laws with respect to any Material
Real Estate Asset or governing its business and the requirements of any permits
issued under such Environmental Laws with respect to any such Real Estate Asset
or the operations of Company or any of its Subsidiaries), except such
non-compliance that, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect.

     4.26. Disclosure. No representation or warranty of any Credit Party
contained in any Credit Document or in any other documents, certificates or
written statements furnished to Lenders by or on behalf of Company or any of its
Subsidiaries for use in connection with the transactions contemplated hereby, at
the time furnished to the Lenders, contained any untrue statement of a material
fact or omitted to state a material fact (known to Company or any of its
Subsidiaries, in the case of any document not furnished by either of them)
necessary in order to make the statements contained herein or therein not
misleading in light of the circumstances in which the same were made. Any
projections and pro forma financial information contained in such materials are
based upon good faith estimates and assumptions believed by Company or any of
its Subsidiaries to be reasonable at the time made, it being recognized by
Lenders that such

than matters of a general economic nature) that, individually or in the
aggregate, could reasonably be expected to result in a Material Adverse Effect
and that have not been disclosed herein or in such other documents, certificates
and statements furnished to Lenders for use in connection with the transactions
contemplated hereby.

preserve and keep in full force and effect its existence and all rights and
franchises, licenses and permits material to its business; provided, no Credit
Party nor any of its Subsidiaries shall be required to preserve any such
existence, right or franchise, license or permit if Company's or such Person's
board of directors (or similar governing body) shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
Company or such Person, and that the loss thereof is not disadvantageous in any
material respect to Company or such Person or to Lenders.

     5.3. Payment of Taxes and Claims. Each Credit Party will, and will cause
each of its Subsidiaries and Unrestricted Subsidiaries to, pay all Taxes imposed
upon it or any of its properties or assets or in respect of any of its income,

provided, no such Tax or claim need be paid if it is being contested in good
faith by appropriate proceedings promptly instituted and diligently conducted,
so long as (a) adequate reserves or other appropriate provision, as shall be
required in conformity with GAAP shall have been made therefor, and (b) in the
case of a charge or claim which has or may become a Lien against any of the
Collateral, such contest proceedings conclusively operate to stay the sale of
any portion of the Collateral to satisfy such Tax or claim. No Credit Party
will, nor

<PAGE>

of its Subsidiaries to, maintain or cause to be maintained in good repair,
working order and condition, ordinary wear and tear excepted, all of its

financially sound and reputable insurers, such public liability insurance, third

Unrestricted Subsidiaries as may customarily be carried or maintained under
similar circumstances by Persons of established reputation engaged in similar
businesses, in each case in such amounts (giving effect to self-insurance), with
such deductibles, covering such risks and otherwise on such terms and conditions
as shall be customary for such Persons, except for such non-compliance that
could not reasonably be expected to result in a Material Adverse Effect. Without
limiting the generality of the foregoing, Company will maintain or cause to be
maintained (a) flood insurance with respect to each Flood Hazard Property that
is located in a community that participates in the National Flood Insurance
Program, in each case in compliance with any applicable regulations of the Board
of Governors of the Federal Reserve System, and (b) replacement value casualty
insurance on the Collateral under such policies of insurance, with such
insurance companies, in such amounts, with such deductibles, and covering such
risks as are at all times carried or maintained under similar circumstances by
Persons of established reputation engaged in similar businesses. Each such
policy of insurance shall (i) name Administrative Agent, on behalf of Lenders as
an additional insured thereunder as its interests may appear and (ii) in the
case of each casualty insurance policy, contain a loss payable clause or
endorsement, satisfactory in form and substance to Administrative Agent, that
names Administrative Agent, on behalf of Lenders as the loss payee thereunder
for any covered loss in excess of $1,000,000 and provides for at least thirty
(30) days' prior written notice to Administrative Agent of any modification or
cancellation of such policy.

     5.6. Inspections; Lenders Meetings. Each Credit Party will, and will cause

authorized representatives designated by any Lender to visit and inspect any of
the properties of any Credit Party and any of its respective Subsidiaries and
all Unrestricted Subsidiaries, to inspect, copy and take extracts from its and
their financial and accounting records, and to discuss its and their affairs,
finances and accounts with its and their officers and independent public
accountants, all upon reasonable notice and at such reasonable times during
normal business hours and as often as may reasonably be requested. Company and
its Subsidiaries will, upon the request of Administrative Agent or Requisite
Lenders, participate in a meeting of Administrative Agent and Lenders once
during each Fiscal Year to be held at Company's corporate offices (or at such
other location as may be agreed to by Company and Administrative Agent) at such
time as may be agreed to by Company and

<PAGE>

Administrative Agent.

     5.7. Compliance with Laws. Each Credit Party will comply, and shall cause
each of its Subsidiaries and Unrestricted Subsidiaries and all other Persons, if
any, on or occupying any Facilities to comply, with the requirements of all
applicable laws, rules, regulations and orders of any governmental authority
(including all Environmental Laws), noncompliance with which could reasonably be

     any other Person in response to (A) any Hazardous Materials Activities the
     existence of which has a reasonable possibility of resulting in one or more
     Environmental Claims having, individually or in the aggregate, a Material
     Adverse Effect, or (B) any Environmental Claims that, individually or in
     the aggregate, have a reasonable possibility of resulting in a Material
     Adverse Effect, and (3) Company's or any of its Subsidiaries' discovery of

     vicinity of any currently owned Facility that could reasonably be expected

     Environmental Claims that could reasonably be expected to have,
     individually or in the aggregate, a Material Adverse Effect or (B) affect
     the ability of Company or any of its Subsidiaries or any Unrestricted
     Subsidiaries to maintain in full force and effect all material Governmental
     Authorizations required under any Environmental Laws for their respective
     operations and (2) any proposed action to be taken by Company or any of its
     Subsidiaries or any Unrestricted Subsidiaries to modify current operations
     in a manner that could reasonably be expected to subject Company or any of

of this sentence shall not be required for (1) those Subsidiaries where Company
has acquired less than 100%, but more than 80% of, the Capital Stock of such
Subsidiary, until such time as any such Subsidiary becomes a wholly-owned
Subsidiary of Company or (2) any Person that becomes a Domestic Subsidiary of
Company after the date hereof if and to the extent and for so long as such
Person's Guaranty of the Obligations or grant of Liens under the Pledge and
Security Agreement would violate applicable law or constitute a default under
the terms of any Acquired Debt of such Person or would obligate it pursuant to
the terms of such Acquired Debt to guarantee or secure any Indebtedness other

the issuance of a guarantee or the granting of Liens in respect of such

Agent requests and otherwise consents to the issuance of a guarantee or the
granting of Liens in respect of such Indebtedness, it being understood that the

of Administrative Agent, each Credit Party will, at its expense, promptly
execute, acknowledge and deliver such further documents and do such other acts
and things as Administrative Agent may reasonably request in order to effect

of the foregoing, each Credit Party (except as otherwise contemplated by Section

<PAGE>

to time (including, without limitation, the execution and delivery of

will cause each of its Subsidiaries and all Unrestricted Subsidiaries to,
satisfy customary corporate formalities, including the holding of regular board

any action, or conduct its affairs in a manner, which is likely to result in the
corporate existence of Company or any of its Subsidiaries or any Unrestricted
Subsidiary being ignored, or in the assets and liabilities of Company or any of
its Subsidiaries or any Unrestricted Subsidiary being substantively consolidated
with those of any other such Person in a bankruptcy, reorganization or other

effectively limit the Unadjusted Eurodollar Rate Component of the interest costs
to Company with respect to an aggregate notional principal amount of not less
than 50% of the aggregate total Indebtedness of Company outstanding from time to
time (based on the assumption that such notional principal amount was a
Eurodollar Rate Loan with an Interest Period of three months).

election of the Person or Persons (whether directors, managers, trustees or
other Persons performing similar functions) having the power to direct or cause
the direction of the management and policies thereof or with any Affiliate of
Company or of any such holder, on terms that are less favorable to Company or

otherwise change the terms of any of the Existing Indentures or any Permitted

change thereto, if the effect of any such amendment or change is to increase the
interest rate payable under any Existing Indenture or any Permitted
Indebtedness, change (to earlier dates) any dates upon which payments of
principal or interest are due thereon, change any event of default or condition
to an event of default with respect thereto (other than to eliminate any such

to the defeasance provisions which are not adverse in any manner to the

obligations of the obligor thereunder or to confer any additional rights on the
holders of such Permitted Indebtedness (or a trustee or other representative on
their behalf) which would be adverse to any Credit Party or Lenders. For the
avoidance of doubt, the foregoing shall not be deemed to prohibit the amendment
of the terms of the Concentric Senior Notes and the Concentric Exchange Notes

Permitted Indebtedness (determined without regard to maturity) if then issued by
Company.

<PAGE>

     with each of the covenants set forth in Section 6.6 or 6.7, as applicable,
     calculated on a pro forma basis as if such Designation had occurred
     immediately prior to the first day of the period of four consecutive fiscal
     quarters most recently ended;

          (iii) no Designation shall be made for any Subsidiary (other than
     Concentric) whose assets, rights or franchises are material to the conduct

     Subsidiaries), taken as a whole; and

          (iv) Company has delivered to the Administrative Agent (x) written

     of such Designation, of an Authorized Officer of Company stating that no
     Event of Default has occurred and is continuing and setting forth
     reasonably detailed calculations demonstrating pro forma compliance with
     Section 6.6 or 6.7, as applicable, in accordance with clause (ii) above.

     applicable, calculated on a pro forma basis as if such RS Designation had
     occurred immediately prior to the first day of the relevant period
     specified in such Section, as applicable;

          (iv) Company has delivered to the Administrative Agent (x) written

     date of such RS Designation, of an Authorized Officer of Company stating
     that no Event of Default has occurred and is continuing and setting forth
     reasonably detailed calculations demonstrating pro forma compliance with
     Section 6.6 or 6.7, as applicable, in accordance with clause (iii) above;
     and

          (v) all Indebtedness of such Subsidiary outstanding and all Liens on
     assets of such Subsidiary existing immediately following the RS Designation
     would, if initially incurred at such time, have been permitted to be
     incurred pursuant to Sections 6.1 and 6.2 without reliance on Section
     6.1(m) or Section 6.2(o), except that, if the Person subject to an RS
     Designation had Indebtedness described in Section 6.1(m) or Liens described
     in Section 6.2(o) at the time such Person was designated an Unrestricted
     Subsidiary, both such Indebtedness and Liens shall be permitted following
     such RS Designation.

          Upon any such RS Designation, Company shall be deemed to have (i)
received a

<PAGE>

return of its Investment in such Unrestricted Subsidiary equal to the lesser of
(x) the amount of such Investment immediately prior to such RS Designation and
(y) the fair market value (as reasonably determined by Company) of the net
assets of such Subsidiary at the time of such RS Designation and (ii) a
permanent Investment in an Unrestricted Subsidiary equal to the excess, if
positive, of the amount referred to in clause (i)(x) above over the amount
referred to in clause (i)(y) above.

     (c) Neither Company nor any Subsidiary shall at any time (x) provide a
Guaranty of any Indebtedness of any Unrestricted Subsidiary, (y) be directly or
indirectly liable for any Indebtedness of any Unrestricted Subsidiary or (z) be
directly or indirectly liable for any other Indebtedness which provides that the
holder thereof may (upon notice, lapse of time or both) declare a default
thereon (or cause such Indebtedness or the payment thereof to be accelerated,
payable or subject to repurchase prior to its final scheduled maturity) upon the
occurrence of a default with respect to any other Indebtedness that is
Indebtedness of an Unrestricted Subsidiary.

     6.16. Telecommunications Assets. No Loan used to provide purchase money
financing for the construction, acquisition or improvement of any
Telecommunications Asset will exceed 80% (or such greater percentage (not in

of each Telecommunications Asset so constructed, acquired or improved after the

to Administrative Agent for the ratable benefit of the Beneficiaries the due and
punctual payment in full of all Obligations when the same shall become due,
whether at stated maturity, by required prepayment, declaration, acceleration,
demand or otherwise (including amounts that would become due but for the
operation of the automatic stay under Section 362(a) of the Bankruptcy Code, 11
U.S.C. ss. 362(a)) (collectively, the "Guaranteed Obligations"); provided that

     7.2. Contribution by Guarantors. All Guarantors desire to allocate among

the event any payment or distribution is made on any

<PAGE>

date by a Guarantor (a "Funding Guarantor") under this Guaranty that exceeds its
Fair Share as of such date, such Funding Guarantor shall be entitled to a
contribution from each of the other Contributing Guarantors in the amount of
such other Contributing Guarantor's Fair Share Shortfall as of such date, with
the result that all such contributions will cause each Contributing Guarantor's
Aggregate Payments to equal its Fair Share as of such date. "Fair Share" means,
with respect to a Contributing Guarantor as of any date of determination, an
amount equal to (a) the ratio of (i) the Fair Share Contribution Amount with
respect to such Contributing Guarantor to (ii) the aggregate of the Fair Share
Contribution Amounts with respect to all Contributing Guarantors multiplied by
(b) the aggregate amount paid or distributed on or before such date by all
Funding Guarantors under this Guaranty in respect of the obligations Guarantied.
"Fair Share Shortfall" means, with respect to a Contributing Guarantor as of any
date of determination, the excess, if any, of the Fair Share of such
Contributing Guarantor over the Aggregate Payments of such Contributing
Guarantor. "Fair Share Contribution Amount" means, with respect to a
Contributing Guarantor as of any date of determination, the maximum aggregate
amount of the obligations of such Contributing Guarantor under this Guaranty
that would not render its obligations hereunder or thereunder subject to
avoidance as a fraudulent transfer or conveyance under Section 548 of Title 11
of the United States Code or any comparable applicable provisions of state law;
provided, solely for purposes of calculating the "Fair Share Contribution
Amount" with respect to any Contributing Guarantor for purposes of this Section
7.2, any assets or liabilities of such Contributing Guarantor arising by virtue
of any rights to subrogation, reimbursement or indemnification or any rights to
or obligations of contribution hereunder shall not be considered as assets or
liabilities of such Contributing Guarantor. "Aggregate Payments" means, with
respect to a Contributing Guarantor as of any date of determination, an amount
equal to (1) the aggregate amount of all payments and distributions made on or
before such date by such Contributing Guarantor in respect of this Guaranty
(including, without limitation, in respect of this Section 7.2), minus (2) the
aggregate amount of all payments received on or before such date by such
Contributing Guarantor from the other Contributing Guarantors as contributions
under this Section 7.2. The amounts payable as contributions hereunder shall be
determined as of the date on which the related payment or distribution is made
by the applicable Funding Guarantor. The allocation among Contributing
Guarantors of their obligations as set forth in this Section 7.2 shall not be
construed in any way to limit the liability of any Contributing Guarantor
hereunder. Each Guarantor is a third party beneficiary to the contribution
agreement set forth in this Section 7.2.

     7.3. Payment by Guarantors. Subject to Section 7.2, Guarantors hereby
jointly and severally agree, in furtherance of the foregoing and not in
limitation of any other right which any Beneficiary may have at law or in equity
against any Guarantor by virtue hereof, that upon the failure of Company to pay
any of the Guaranteed Obligations when and as the same shall become due, whether
at stated maturity, by required prepayment, declaration, acceleration, demand or
otherwise (including amounts that would become due but for the operation of the
automatic stay under Section 362(a) of the Bankruptcy Code, 11 U.S.C. ss.
362(a)), Guarantors will upon demand pay, or cause to be paid, in Cash, to
Administrative Agent for the ratable benefit of Beneficiaries, an amount equal
to the sum of the unpaid principal amount of all Guaranteed Obligations then due
as aforesaid, accrued and unpaid interest on such Guaranteed Obligations

<PAGE>

(including interest which, but for Company's becoming the subject of a case
under the Bankruptcy Code, would have accrued on such Guaranteed Obligations,
whether or not a claim is allowed against Company for such interest in the
related bankruptcy case) and all other Guaranteed Obligations then owed to
Beneficiaries as aforesaid.

     7.4. Liability of Guarantors Absolute. Each Guarantor agrees that its
obligations hereunder are irrevocable, absolute, independent and unconditional
and shall not be affected by any circumstance which constitutes a legal or
equitable discharge of a guarantor or surety other than payment in full of the
Guaranteed Obligations. In furtherance of the foregoing and without limiting the
generality thereof, each Guarantor agrees as follows:

     (a) this Guaranty is a guaranty of payment when due and not of
collectability. This Guaranty is a primary obligation of each Guarantor and not
merely a contract of surety;

     (b) Administrative Agent may enforce this Guaranty upon the occurrence of
an Event of Default notwithstanding the existence of any dispute between Company
and any Beneficiary with respect to the existence of such Event of Default;

     (c) the obligations of each Guarantor hereunder are independent of the
obligations of Company and the obligations of any other guarantor (including any
other Guarantor) of the obligations of Company, and a separate action or actions
may be brought and prosecuted against such Guarantor whether or not any action
is brought against Company or any of such other guarantors and whether or not
Company is joined in any such action or actions;

     (d) payment by any Guarantor of a portion, but not all, of the Guaranteed
Obligations shall in no way limit, affect, modify or abridge any Guarantor's
liability for any portion of the Guaranteed Obligations which has not been paid.
Without limiting the generality of the foregoing, if Administrative Agent is
awarded a judgment in any suit brought to enforce any Guarantor's covenant to
pay a portion of the Guaranteed Obligations, such judgment shall not be deemed
to release such Guarantor from its covenant to pay the portion of the Guaranteed
Obligations that is not the subject of such suit, and such judgment shall not,
except to the extent satisfied by such Guarantor, limit, affect, modify or
abridge any other Guarantor's liability hereunder in respect of the Guaranteed
Obligations;

     (e) any Beneficiary, upon such terms as it deems appropriate, without
notice or demand and without affecting the validity or enforceability hereof or
giving rise to any reduction, limitation, impairment, discharge or termination
of any Guarantor's liability hereunder, from time to time may to the maximum
extent permitted by law (i) renew, extend, accelerate, increase the rate of
interest on, or otherwise change the time, place, manner or terms of payment of
the Guaranteed Obligations; (ii) settle, compromise, release or discharge, or
accept or refuse any offer of performance with respect to, or substitutions for,
the Guaranteed Obligations or any agreement relating thereto and/or subordinate
the payment of the same to the payment of any other obligations; (iii) request
and accept other guaranties of the Guaranteed Obligations and take and hold
security for the payment hereof or the Guaranteed Obligations; (iv) release,
surrender,

<PAGE>

exchange, substitute, compromise, settle, rescind, waive, alter, subordinate or
modify, with or without consideration, any security for payment of the
Guaranteed Obligations, any other guaranties of the Guaranteed Obligations, or
any other obligation of any Person (including any other Guarantor) with respect
to the Guaranteed Obligations; (v) enforce and apply any security now or
hereafter held by or for the benefit of such Beneficiary in respect hereof or
the Guaranteed Obligations and direct the order or manner of sale thereof, or
exercise any other right or remedy that such Beneficiary may have against any
such security, in each case as such Beneficiary in its discretion may determine
consistent herewith or the applicable Hedge Agreement and any applicable
security agreement, including foreclosure on any such security pursuant to one
or more judicial or nonjudicial sales, whether or not every aspect of any such
sale is commercially reasonable, and even though such action operates to impair
or extinguish any right of reimbursement or subrogation or other right or remedy
of any Guarantor against Company or any security for the Guaranteed Obligations;
and (vi) exercise any other rights available to it under the Credit Documents or
the Hedge Agreements; and

     (f) this Guaranty and the obligations of Guarantors hereunder shall be
valid and enforceable and shall not, to the maximum extent permitted by law, be
subject to any reduction, limitation, impairment, discharge or termination for
any reason (other than payment in full of the Guaranteed Obligations), including
the occurrence of any of the following, whether or not any Guarantor shall have
had notice or knowledge of any of them: (i) any failure or omission to assert or
enforce or agreement or election not to assert or enforce, or the stay or
enjoining, by order of court, by operation of law or otherwise, of the exercise
or enforcement of, any claim or demand or any right, power or remedy (whether
arising under the Credit Documents or the Hedge Agreements, at law, in equity or
otherwise) with respect to the Guaranteed Obligations or any agreement relating
thereto, or with respect to any other guaranty of or security for the payment of
the Guaranteed Obligations; (ii) any rescission, waiver, amendment or
modification of, or any consent to departure from, any of the terms or
provisions (including provisions relating to events of default) hereof, any of
the other Credit Documents, any of the Hedge Agreements or any agreement or
instrument executed pursuant thereto, or of any other guaranty or security for
the Guaranteed Obligations, in each case whether or not in accordance with the
terms hereof or such Credit Document, such Hedge Agreement or any agreement
relating to such other guaranty or security; (iii) the Guaranteed Obligations,
or any agreement relating thereto, at any time being found to be illegal,
invalid or unenforceable in any respect; (iv) the application of payments
received from any source (other than payments received pursuant to the other
Credit Documents or any of the Hedge Agreements or from the proceeds of any
security for the Guaranteed Obligations, except to the extent such security also
serves as collateral for indebtedness other than the Guaranteed Obligations) to
the payment of indebtedness other than the Guaranteed Obligations, even though
any Beneficiary might have elected to apply such payment to any part or all of
the Guaranteed Obligations; (v) any Beneficiary's consent to the change,
reorganization or termination of the corporate structure or existence of Company
or any of its Subsidiaries and to any corresponding restructuring of the
Guaranteed Obligations; (vi) any failure to perfect or continue perfection of a
security interest in any collateral which secures any of the Guaranteed
Obligations; (vii) any defenses, set-offs or counterclaims which Company may
allege or assert against any Beneficiary in respect of the Guaranteed
Obligations, including failure of

<PAGE>

consideration, breach of warranty, payment, statute of frauds, statute of
limitations, accord and satisfaction and usury; and (viii) any other act or
thing or omission, or delay to do any other act or thing, which may or might in
any manner or to any extent vary the risk of any Guarantor as an obligor in
respect of the Guaranteed Obligations.

     7.5. Waivers by Guarantors. Each Guarantor hereby waives, for the benefit
of Beneficiaries, to the maximum extent permitted by law: (a) any right to
require any Beneficiary, as a condition of payment or performance by such
Guarantor, to (i) proceed against Company, any other guarantor (including any
other Guarantor) of the Guaranteed Obligations or any other Person, (ii) proceed
against or exhaust any security held from Company, any such other guarantor or
any other Person, (iii) proceed against or have resort to any balance of any
Deposit Account or credit on the books of any Beneficiary in favor of Company or
any other Person, or (iv) pursue any other remedy in the power of any
Beneficiary whatsoever; (b) any defense arising by reason of the incapacity,
lack of authority or any disability or other defense of Company or any other
Guarantor including any defense based on or arising out of the lack of validity
or the unenforceability of the Guaranteed Obligations or any agreement or
instrument relating thereto or by reason of the cessation of the liability of
Company or any other Guarantor from any cause other than payment in full of the
Guaranteed Obligations; (c) any defense based upon any statute or rule of law
which provides that the obligation of a surety must be neither larger in amount
nor in other respects more burdensome than that of the principal; (d) any
defense based upon any Beneficiary's errors or omissions in the administration
of the Guaranteed Obligations, except behavior which amounts to bad faith; (e)
(i) any principles or provisions of law, statutory or otherwise, which are or
might be in conflict with the terms hereof and any legal or equitable discharge
of such Guarantor's obligations hereunder, (ii) the benefit of any statute of
limitations affecting such Guarantor's liability hereunder or the enforcement
hereof, (iii) any rights to set-offs, recoupments and counterclaims, and (iv)
promptness, diligence and any requirement that any Beneficiary protect, secure,
perfect or insure any security interest or lien or any property subject thereto;
(f) notices, demands, presentments, protests, notices of protest, notices of
dishonor and notices of any action or inaction, including acceptance hereof,
notices of default hereunder, the Hedge Agreements or any agreement or
instrument related thereto, notices of any renewal, extension or modification of
the Guaranteed Obligations or any agreement related thereto, notices of any
extension of credit to Company and notices of any of the matters referred to in
Section 7.4 and any right to consent to any thereof; and (g) any defenses or
benefits that may be derived from or afforded by law which limit the liability
of or exonerate guarantors or sureties, or which may conflict with the terms
hereof.

     7.6. Guarantors' Rights of Subrogation, Contribution, etc. Until the
Guaranteed Obligations shall have been indefeasibly paid in full and the
Commitments shall have terminated, each Guarantor hereby waives the exercise of
any claim, right or remedy, direct or indirect, that such Guarantor now has or
may hereafter have against Company or any other Guarantor or any of its assets
in connection with this Guaranty or the performance by such Guarantor of its
obligations hereunder, in each case whether such claim, right or remedy arises
in equity, under contract, by statute, under common law or otherwise and
including without limitation (a) any right of subrogation, reimbursement or
indemnification that such Guarantor now has or may hereafter

<PAGE>

have against Company with respect to the Guaranteed Obligations, (b) any right
to enforce, or to participate in, any claim, right or remedy that any
Beneficiary now has or may hereafter have against Company, and (c) any benefit
of, and any right to participate in, any collateral or security now or hereafter
held by any Beneficiary. In addition, until the Guaranteed Obligations shall
have been indefeasibly paid in full and the Commitments shall have terminated,
each Guarantor shall withhold exercise of any right of contribution such
Guarantor may have against any other guarantor (including any other Guarantor)
of the Guaranteed Obligations, including, without limitation, any such right of
contribution as contemplated by Section 7.2. Each Guarantor further agrees that,
to the extent the waiver or agreement to withhold the exercise of its rights of
subrogation, reimbursement, indemnification and contribution as set forth herein
is found by a court of competent jurisdiction to be void or voidable for any
reason, any rights of subrogation, reimbursement or indemnification such
Guarantor may have against Company or against any collateral or security, and
any rights of contribution such Guarantor may have against any such other
guarantor, shall be junior and subordinate to any rights any Beneficiary may
have against Company, to all right, title and interest any Beneficiary may have
in any such collateral or security, and to any right any Beneficiary may have
against such other guarantor. If any amount shall be paid to any Guarantor on
account of any such subrogation, reimbursement, indemnification or contribution
rights at any time when all Guaranteed Obligations shall not have been finally
and indefeasibly paid in full, such amount shall be held in trust for
Administrative Agent on behalf of Beneficiaries and shall forthwith be paid over
to Administrative Agent for the benefit of Beneficiaries to be credited and
applied against the Guaranteed Obligations, whether matured or unmatured, in
accordance with the terms hereof.

     7.7. Subordination of Other Obligations. Any Indebtedness of Company or any
Guarantor now or hereafter held by any Guarantor (the "Obligee Guarantor") is
hereby subordinated in right of payment to the Guaranteed Obligations, and any
such indebtedness collected or received by the Obligee Guarantor after an Event
of Default has occurred and is continuing shall be held in trust for
Administrative Agent on behalf of Beneficiaries and shall forthwith be paid over
to Administrative Agent for the benefit of Beneficiaries to be credited and
applied against the Guaranteed Obligations but without affecting, impairing or
limiting in any manner the liability of the Obligee Guarantor under any other
provision hereof.

     7.8. Continuing Guaranty. This Guaranty is a continuing guaranty and shall
remain in effect until all of the Guaranteed Obligations shall have been finally
and indefeasibly paid in full and the Commitments shall have terminated. Each
Guarantor hereby irrevocably waives any right to revoke this Guaranty as to
future transactions giving rise to any Guaranteed Obligations.

     7.9. Authority of Guarantors or Company. It is not necessary for any
Beneficiary to inquire into the capacity or powers of any Guarantor or Company
or the officers, directors or any agents acting or purporting to act on behalf
of any of them.

     7.10. Financial Condition of Company. Any Credit Extension may be made to
Company or continued from time to time, and any Hedge Agreements may be entered
into from time to time, in each case without notice to or authorization from any
Guarantor regardless of the

<PAGE>

financial or other condition of Company at the time of any such grant or
continuation or at the time such Hedge Agreement is entered into, as the case
may be. No Beneficiary shall have any obligation to disclose or discuss with any
Guarantor its assessment, or any Guarantor's assessment, of the financial
condition of Company. Each Guarantor has adequate means to obtain information
from Company on a continuing basis concerning the financial condition of Company
and its ability to perform its obligations under the Credit Documents and the
Hedge Agreements, and each Guarantor assumes the responsibility for being and
keeping informed of the financial condition of Company and of all circumstances
bearing upon the risk of nonpayment of the Guaranteed Obligations. Each
Guarantor hereby waives and relinquishes any duty on the part of any Beneficiary
to disclose any matter, fact or thing relating to the business, operations or
conditions of Company now known or hereafter known by any Beneficiary.

     7.11. Bankruptcy, etc. (a) So long as any Guaranteed Obligations remain
outstanding, no Guarantor shall, without the prior written consent of
Administrative Agent acting pursuant to the instructions of Requisite Lenders,
commence or join with any other Person in commencing any bankruptcy,
reorganization or insolvency case or proceeding of or against Company or any
other Guarantor. The obligations of Guarantors hereunder shall not be reduced,
limited, impaired, discharged, deferred, suspended or terminated by any case or
proceeding, voluntary or involuntary, involving the bankruptcy, insolvency,
receivership, reorganization, liquidation or arrangement of Company or any other
Guarantor or by any defense which Company or any other Guarantor may have by
reason of the order, decree or decision of any court or administrative body
resulting from any such proceeding.

     (b) Each Guarantor acknowledges and agrees that any interest on any portion
of the Guaranteed Obligations which accrues after the commencement of any case
or proceeding referred to in clause (a) above (or, if interest on any portion of
the Guaranteed Obligations ceases to accrue by operation of law by reason of the
commencement of such case or proceeding, such interest as would have accrued on
such portion of the Guaranteed Obligations if such case or proceeding had not
been commenced) shall be included in the Guaranteed Obligations because it is
the intention of Guarantors and Beneficiaries that the Guaranteed Obligations
which are Guaranteed by Guarantors pursuant hereto should be determined without
regard to any rule of law or order which may relieve Company of any portion of
such Guaranteed Obligations. Guarantors will permit any trustee in bankruptcy,
receiver, debtor in possession, assignee for the benefit of creditors or similar
person to pay Administrative Agent, or allow the claim of Administrative Agent
in respect of, any such interest accruing after the date on which such case or
proceeding is commenced.

     (c) In the event that all or any portion of the Guaranteed Obligations are
paid by Company, the obligations of Guarantors hereunder shall continue and
remain in full force and effect or be reinstated, as the case may be, in the
event that all or any part of such payment(s) are rescinded or recovered
directly or indirectly from any Beneficiary as a preference, fraudulent transfer
or otherwise, and any such payments which are so rescinded or recovered shall
constitute Guaranteed Obligations for all purposes hereunder.

<PAGE>

     7.12. Notice of Events. As soon as any Guarantor obtains knowledge thereof,
such Guarantor shall give Administrative Agent written notice of any condition
or event which has resulted in (i) a material adverse change in the financial
condition of any Guarantor or Company or (ii) a breach of or noncompliance with
any term, condition or covenant contained herein, any other Credit Document, any
Hedge Agreement or any other document delivered pursuant hereto or thereto.

     7.13. Discharge of Guaranty Upon Sale of Guarantor. If all of the Capital
Stock of any Guarantor or any of its successors in interest hereunder shall be
sold or otherwise disposed of (including by merger or consolidation) in
accordance with the terms and conditions hereof, the Guaranty of such Guarantor
or such successor in interest, as the case may be, hereunder, and such entity's
pledge as a Grantor under the Pledge and Security Agreement shall automatically
be discharged and released without any further action by any Beneficiary or any
other Person effective as of the time of such Asset Sale, and Administrative
Agent will, at the request and expense of Company execute all instruments as may
be reasonably necessary to accomplish the same.

such holder or holders), to cause, that Indebtedness to become or be declared
due and payable (or redeemable) prior to its stated maturity or the stated
maturity of any underlying obligation, as the case may be; or

SECTION 9. AGENTS

     9.1. Appointment of Agents. GSCP and TDSI are hereby appointed Joint Lead
Arrangers, and GSCP is hereby appointed Syndication Agent hereunder, and each

TD is hereby appointed Administrative Agent hereunder and under the other Credit

agent in accordance with the terms hereof and the other Credit Documents.
Barclays and Chase are hereby appointed Co-Documentation Agents hereunder, and
each Lender hereby authorizes each of the Co-Documentation Agents to act as its

Agent hereby agrees to act upon the express conditions contained herein and the
other Credit Documents, as applicable. The provisions of this Section 9 are
solely for the benefit of Agents and Lenders and no Credit Party shall have any
rights as a third party beneficiary of any of the provisions thereof. In
performing its functions and duties hereunder, each Agent shall act solely as an
agent of Lenders and does not assume and shall not be deemed to have assumed any
obligation towards or relationship of agency or trust with or for Company or any
of its Subsidiaries. Each of Joint Lead Arrangers, Syndication Agent and
Co-Documentation Agents, without consent of or notice to any party hereto, may

delegated or granted to such Agent by the terms hereof and thereof, together
with such powers, rights and remedies as are reasonably incidental thereto. Each
Agent shall have only those duties and responsibilities that are expressly
specified herein and the other Credit Documents. Each Agent may exercise such
powers, rights and remedies and perform such duties by or through its agents or
employees. No Agent shall have, by reason hereof or any of the other Credit
Documents, a fiduciary relationship in respect of any Lender; and nothing herein
or any of the other Credit Documents, expressed or implied, is intended to or
shall be so construed as to impose upon any Agent any obligations in respect
hereof or any of the other Credit Documents except as expressly set forth herein
or therein.

     9.3. General Immunity.

<PAGE>

     (a) No Responsibility for Certain Matters. No Agent shall be responsible to
any Lender for the execution, effectiveness, genuineness, validity,
enforceability, collectability or sufficiency hereof or any other Credit
Document or for any representations, warranties, recitals or statements made
herein or therein or made in any written or oral statements or in any financial
or other statements, instruments, reports or certificates or any other documents
furnished or made by any of Agent to Lenders or by or on behalf of any Credit
Party to any Agent or any Lender in connection with the Credit Documents and the
transactions contemplated thereby or for the financial condition or business
affairs of any Credit Party or any other Person liable for the payment of any
Obligations, nor shall any Agent be required to ascertain or inquire as to the
performance or observance of any of the terms, conditions, provisions, covenants
or agreements contained in any of the Credit Documents or as to the use of the
proceeds of the Loans or as to the existence or possible existence of any Event
of Default or Default. Anything contained herein to the contrary
notwithstanding, Administrative Agent shall not have any liability arising from
confirmations of the amount of outstanding Loans or the component amounts
thereof.

     (b) Exculpatory Provisions. No Agent nor any of its officers, partners,
directors, employees or agents shall be liable to Lenders for any action taken
or omitted by any Agent under or in connection with any of the Credit Documents
except to the extent caused by such Agent's gross negligence or willful
misconduct. Each Agent shall be entitled to refrain from any act or the taking
of any action (including the failure to take an action) in connection herewith
or any of the other Credit Documents or from the exercise of any power,
discretion or authority vested in it hereunder or thereunder unless and until
such Agent shall have received instructions in respect thereof from Requisite
Lenders (or such other Lenders as may be required to give such instructions
under Section 10.5) and, upon receipt of such instructions from Requisite
Lenders (or such other Lenders, as the case may be), such Agent shall be
entitled to act or (where so instructed) refrain from acting, or to exercise
such power, discretion or authority, in accordance with such instructions.
Without prejudice to the generality of the foregoing, (i) each Agent shall be
entitled to rely, and shall be fully protected in relying, upon any
communication, instrument or document believed by it to be genuine and correct
and to have been signed or sent by the proper Person or Persons, and shall be
entitled to rely and shall be protected in relying on opinions and judgments of
attorneys (who may be attorneys for Company and its Subsidiaries), accountants,
experts and other professional advisors selected by it; and (ii) no Lender shall
have any right of action whatsoever against any Agent as a result of such Agent
acting or (where so instructed) refraining from acting hereunder or any of the
other Credit Documents in accordance with the instructions of Requisite Lenders
(or such other Lenders as may be required to give such instructions under
Section 10.5).

     9.4. Agents Entitled to Act as Lender. The agency hereby created shall in
no way impair or affect any of the rights and powers of, or impose any duties or
obligations upon, any Agent in its individual capacity as a Lender hereunder.
With respect to its participation in the Loans, each Agent shall have the same
rights and powers hereunder as any other Lender and may exercise the same as if
it were not performing the duties and functions delegated to it hereunder, and
the term "Lender" shall, unless the context clearly otherwise indicates, include
each Agent in

<PAGE>

its individual capacity. Any Agent and its Affiliates may accept deposits from,
lend money to and generally engage in any kind of banking, trust, financial
advisory or other business with Company or any of its Affiliates as if it were
not performing the duties specified herein, and may accept fees and other
consideration from Company for services in connection herewith and otherwise
without having to account for the same to Lenders.

     9.5. Lenders' Representations, Warranties and Acknowledgment.

     (a) Each Lender represents and warrants that it has made its own
independent investigation of the financial condition and affairs of Company and
its Subsidiaries in connection with Credit Extensions hereunder and that it has
made and shall continue to make its own appraisal of the creditworthiness of
Company and its Subsidiaries. No Agent shall have any duty or responsibility,
either initially or on a continuing basis, to make any such investigation or any
such appraisal on behalf of Lenders or to provide any Lender with any credit or
other information with respect thereto, whether coming into its possession
before the making of the Loans or at any time or times thereafter, and no Agent
shall have any responsibility with respect to the accuracy of or the
completeness of any information provided to Lenders.

     (b) Each Lender, by delivering its signature page to this Agreement and
funding its Tranche A Term Loan, Tranche B Term Loan and/or a Revolving Loan on
the Closing Date, shall be deemed to have acknowledged receipt of, and consented
to and approved, each Credit Document and each other document required to be
approved by any Agent, Requisite Lenders or Lenders, as applicable on the
Closing Date.

     9.6. Right to Indemnity. Each Lender, in proportion to its Pro Rata Share,
severally agrees to indemnify each Agent, to the extent that such Agent shall
not have been reimbursed by any Credit Party, for and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses (including counsel fees and disbursements) or disbursements of
any kind or nature whatsoever which may be imposed on, incurred by or asserted
against such Agent in exercising its powers, rights and remedies or performing
its duties hereunder or under the other Credit Documents or otherwise in its
capacity as such Agent in any way relating to or arising out hereof or the other
Credit Documents; provided, no Lender shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting from such Agent's gross negligence or
willful misconduct. If any indemnity furnished to any Agent for any purpose
shall, in the opinion of such Agent, be insufficient or become impaired, such
Agent may call for additional indemnity and cease, or not commence, to do the
acts indemnified against until such additional indemnity is furnished; provided,
in no event shall this sentence require any Lender to indemnify any Agent
against any liability, obligation, loss, damage, penalty, action, judgment,
suit, cost, expense or disbursement in excess of such Lender's Pro Rata Share
thereof; and provided further, this sentence shall not be deemed to require any
Lender to indemnify any Agent against any liability, obligation, loss, damage,
penalty, action, judgment, suit, cost, expense or disbursement described in the
proviso in the immediately preceding sentence.

<PAGE>

     9.7. Successor Administrative Agent; Joint Lead Arrangers.

     (a) Administrative Agent. Administrative Agent may resign at any time by
giving thirty (30) days' prior written notice thereof to Lenders and Company.
Upon any such notice of resignation, Requisite Lenders shall have the right,
upon five Business Days' notice to Company, to appoint a successor
Administrative Agent. Upon the acceptance of any appointment as Administrative
Agent hereunder by a successor Administrative Agent, that successor
Administrative Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Administrative Agent.
After any retiring Administrative Agent's resignation hereunder as
Administrative Agent, the provisions of this Section 9 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was
Administrative Agent hereunder.

     (b) Joint Lead Arrangers. Either Joint Lead Arranger may resign at any time
by giving thirty (30) days' prior written notice thereof to the other Joint Lead
Arranger, Lenders and Company. Upon any such notice of resignation, the
remaining Joint Lead Arranger and Requisite Lenders shall have the right, upon
five Business Days' notice to Company, to appoint a successor Joint Lead
Arranger. Upon the acceptance of any appointment as Joint Lead Arranger
hereunder by a successor Joint Lead Arranger, that successor Joint Lead Arranger
shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Joint Lead Arranger. After any retiring
Joint Lead Arranger's resignation hereunder as Joint Lead Arranger, the
provisions of this Section 9 shall inure to its benefit as to any actions taken
or omitted to be taken by it while it was Joint Lead Arranger hereunder.

     9.8. Collateral Documents and Guaranty.

     (a) Administrative Agent as Agent under Collateral Documents and Guaranty.
Each Lender hereby further authorizes Administrative Agent, on behalf of and for
the benefit of Lenders, to be the agent for and representative of Lenders with
respect to the Guaranty, the Collateral and the Collateral Documents. Subject to
Section 10.5, without further written consent or authorization from Lenders,
Administrative Agent may execute any documents or instruments necessary to (i)
release any Lien encumbering any item of Collateral that is the subject of a
sale or other disposition of assets permitted hereby or to which Requisite
Lenders (or such other Lenders as may be required to give such consent under
Section 10.5) have otherwise consented or (ii) release any Guarantor from the
Guaranty and the Pledge and Security Agreement pursuant to Section 7.13 or with
respect to which Requisite Lenders (or such other Lenders as may be required to
give such consent under Section 10.5) have otherwise consented.

     (b) Administrative Agent's Right to Realize on Collateral and Enforce
Guaranty. Anything contained in any of the Credit Documents to the contrary
notwithstanding, Company, Administrative Agent and each Lender hereby agree that
(i) no Lender shall have any right individually to realize upon any of the
Collateral or to enforce the Guaranty, it being understood and agreed that all
powers, rights and remedies hereunder may be exercised solely by Administrative
Agent, on behalf of Lenders in accordance with the terms hereof, and (ii) in the

<PAGE>

event of a foreclosure by Administrative Agent on any of the Collateral pursuant
to a public or private sale, Administrative Agent or any Lender may be the
purchaser of any or all of such Collateral at any such sale and Administrative
Agent, as agent for and representative of Lenders (but not any Lender or Lenders
in its or their respective individual capacities unless Requisite Lenders shall
otherwise agree in writing) shall be entitled, for the purpose of bidding and
making settlement or payment of the purchase price for all or any portion of the
Collateral sold at any such public sale, to use and apply any of the Obligations
as a credit on account of the purchase price for any collateral payable by
Administrative Agent at such sale.

     (c) Supplemental Collateral Agent. It is the purpose hereof and the other
Credit Documents that there shall be no violation of any law of any jurisdiction
denying or restricting the right of banking corporations or associations to
transact business as agent or trustee in such jurisdiction. It is recognized
that in case of litigation hereunder or any of the other Credit Documents, and
in particular in case of the enforcement of any of the Credit Documents, or in
case Administrative Agent deems that by reason of any present or future law of
any jurisdiction it may not exercise any of the rights, powers or remedies
granted herein or in any of the other Credit Documents or take any other action
which may be desirable or necessary in connection therewith, it may be necessary
that Administrative Agent appoint an additional individual or institution as a
separate trustee, co-trustee, collateral agent or collateral co-agent (a
"Supplemental Collateral Agent"). In the event that Administrative Agent
appoints a Supplemental Collateral Agent with respect to any Collateral, (i)
each and every right, power, privilege or duty expressed or intended hereby or
any of the other Credit Documents to be exercised by or vested in or conveyed to
Administrative Agent with respect to such Collateral shall be exercisable by and
vest in such Supplemental Collateral Agent to the extent, and only to the
extent, necessary to enable such Supplemental Collateral Agent to exercise such
rights, powers and privileges with respect to such Collateral and to perform
such duties with respect to such Collateral, and every covenant and obligation
contained in the Credit Documents and necessary to the exercise or performance
thereof by such Supplemental Collateral Agent shall run to and be enforceable by
either Agent or such Supplemental Collateral Agent, and (ii) the provisions of
this Section 9 and of Sections 10.2 and 10.3 that refer to Administrative Agent
shall inure to the benefit of such Supplemental Collateral Agent and all
references therein to Administrative Agent shall be deemed to be references to
Administrative Agent and/or such Supplemental Collateral Agent, as the context
may require. Should any instrument in writing from Company or any other Credit
Party be required by any Supplemental Collateral Agent so appointed by
Administrative Agent for more fully and certainly vesting in and confirming to
him or it such rights, powers, privileges and duties, Company shall, or shall
cause such Credit Party to, execute, acknowledge and deliver any and all such
instruments promptly upon request by Administrative Agent. In case any
Supplemental Collateral Agent, or a successor thereto, shall die, become
incapable of acting, resign or be removed, all the rights, powers, privileges
and duties of such Supplemental Collateral Agent, to the extent permitted by
law, shall vest in and be exercised by Administrative Agent until the
appointment of a new Supplemental Collateral Agent.

Lender, the address as indicated on Appendix C or otherwise indicated to

the United States mail with postage prepaid and properly addressed; provided, no
notice to any Agent shall be effective until received by such Agent.

     10.2. Expenses. Whether or not the transactions contemplated hereby shall
be consummated, Company agrees to pay promptly (a) all the actual and reasonable
costs and expenses of preparation of the Credit Documents and any consents,
amendments, waivers or other modifications thereto; (b) all the costs of
furnishing all opinions by counsel for Company and the other Credit Parties; (c)
the reasonable fees, expenses and disbursements of counsel to Agents (in each
case including allocated costs of internal counsel) in connection with the
negotiation, preparation, execution and administration of the Credit Documents
and any consents, amendments, waivers or other modifications thereto and any
other documents or matters requested by Company; (d) all the actual costs and
reasonable expenses of creating and perfecting Liens in favor of Administrative
Agent, for the benefit of Lenders pursuant hereto, including filing and

incurred by any Agent and Lenders in enforcing any Obligations of or in
collecting any payments due from any Credit Party hereunder or under the other
Credit Documents by reason of such Default or Event of Default (including in
connection with the sale of, collection from, or other realization upon any of
the Collateral or the enforcement of the Guaranty) or in connection with any
refinancing or restructuring of the credit arrangements provided hereunder in
the nature of a "work-out" or pursuant to any insolvency or bankruptcy cases or
proceedings.

<PAGE>

     10.3. Indemnity. In addition to the payment of expenses pursuant to Section
10.2, whether or not the transactions contemplated hereby shall be consummated,
each Credit Party agrees to defend (subject to Indemnitees' selection of
counsel), indemnify, pay and hold harmless, each Agent and Lender and the
officers, partners, directors, trustees, employees, agents and Affiliates of
each Agent and each Lender (each, an "Indemnitee"), from and against any and all
Indemnified Liabilities; provided, no Credit Party shall have any obligation to
any Indemnitee hereunder with respect to any Indemnified Liabilities to the
extent such Indemnified Liabilities arise from the gross negligence or willful
misconduct of that Indemnitee. To the extent that the undertakings to defend,
indemnify, pay and hold harmless set forth in this Section 10.3 may be
unenforceable in whole or in part because they are violative of any law or
public policy, the applicable Credit Party shall contribute the maximum portion
that it is permitted to pay and satisfy under applicable law to the payment and
satisfaction of all Indemnified Liabilities incurred by Indemnitees or any of
them.

     10.4. Set-Off. In addition to any rights now or hereafter granted under
applicable law and not by way of limitation of any such rights, upon the
occurrence of any Event of Default each Lender is hereby authorized by each
Credit Party at any time or from time to time subject to the consent of
Administrative Agent (such consent not to be unreasonably withheld or delayed),
without notice to any Credit Party or to any other Person (other than
Administrative Agent), any such notice being hereby expressly waived, to set off
and to appropriate and to apply any and all deposits (general or special,
including Indebtedness evidenced by certificates of deposit, whether matured or
unmatured, but not including trust accounts) and any other Indebtedness at any
time held or owing by such Lender to or for the credit or the account of any
Credit Party against and on account of the obligations and liabilities of any
Credit Party to such Lender hereunder and under the other Credit Documents,
including all claims of any nature or description arising out of or connected
hereto or with any other Credit Document, irrespective of whether or not (a)
such Lender shall have made any demand hereunder or (b) the principal of or the
interest on the Loans or any other amounts due hereunder shall have become due
and payable pursuant to Section 2 and although such obligations and liabilities,
or any of them, may be contingent or unmatured. Each Credit Party hereby further
grants to Administrative Agent and each Lender a security interest in all
Deposit Accounts maintained with Administrative Agent or such Lender as security
for the Obligations.

     10.5. Amendments and Waivers. Requisite Lenders' Consent. (a) Subject to
Section 10.5(b) and 10.5(c), no amendment, modification, termination or waiver
of any provision of the Credit Documents, or consent to any departure by any
Credit Party therefrom, shall in any event be effective without the written
concurrence of the Requisite Lenders. For the avoidance of doubt, the provision
of New Term Loans and/or New Revolving Loans on the terms as specified in
Section 2.22 shall not require the consent of the Requisite Lenders.

     (b) Affected Lenders' Consent. Without the written consent of each Lender
(other than a Defaulting Lender) that would be affected thereby, no amendment,
modification, termination, or consent shall be effective if the effect thereof
would:

<PAGE>

          (i) extend the scheduled final maturity of any Loan or Note or the
     Tranche A Commitment Termination Date;

          (ii) waive, reduce or postpone any scheduled repayment (but not
     prepayment);

          (iii) reduce the rate of interest on any Loan (other than any waiver
     of any increase in the interest rate applicable to any Loan pursuant to
     Section 2.8) or any fee payable hereunder;

          (iv) extend the time for payment of any such interest or fees;

          (v) reduce the principal amount of any Loan;

          (vi) amend, modify, terminate or waive any provision of this Section
     10.5(b) or Section 10.5(c);

          (vii) amend the definition of "Requisite Lenders" or "Pro Rata Share";
     provided, with the consent of Requisite Lenders, additional extensions of
     credit pursuant hereto may be included in the determination of "Requisite
     Lenders" or "Pro Rata Share" on substantially the same basis as the Term
     Loan Commitments, the Term Loans, the Revolving Credit Commitments and the
     Revolving Loans are included on the Closing Date;

          (viii) release or otherwise subordinate all or substantially all of
     the Collateral or all or substantially all of the Guarantors from the
     Guaranty except as expressly provided in the Credit Documents; or

          (ix) consent to the assignment or transfer by any Credit Party of any
     of its rights and obligations under any Credit Document.

     (c) Other Consents. No amendment, modification, termination or waiver of
any provision of the Credit Documents, or consent to any departure by any Credit
Party therefrom, shall:

          (i) increase any Commitment of any Lender over the amount thereof then
     in effect without the consent of such Lender; provided, no amendment,
     modification or waiver of any condition precedent, covenant, Default or
     Event of Default shall constitute an increase in any Commitment of any
     Lender;

          (ii) amend the definition of "Requisite Class Lenders" without the
     consent of Requisite Class Lenders of each Class; provided, with the
     consent of the Requisite Lenders, additional extensions of credit pursuant
     hereto may be included in the determination of such "Requisite Class
     Lenders" on substantially the same basis as the

<PAGE>

     Term Loan Commitments, the Term Loans, the Revolving Credit Commitments and
     the Revolving Loans are included on the Closing Date;

          (iii) alter the required application of any repayments or prepayments
     as between Classes pursuant to Section 2.13 without the consent of
     Requisite Class Lenders of each Class which is being allocated a lesser
     repayment or prepayment as a result thereof; provided, Requisite Lenders
     may waive, in whole or in part, any prepayment so long as the application,
     as between Classes, of any portion of such prepayment which is still
     required to be made is not altered; or

          (iv) amend, modify, terminate or waive any provision of Section 9 as
     the same applies to any Agent, or any other provision hereof as the same
     applies to the rights or obligations of any Agent, in each case without the
     consent of such Agent.

     (d) Execution of Amendments, etc. Administrative Agent may, but shall have
no obligation to, with the concurrence of any Lender, execute amendments,
modifications, waivers or consents on behalf of such Lender. Any waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which it was given. No notice to or demand on any Credit Party in
any case shall entitle any Credit Party to any other or further notice or demand
in similar or other circumstances. Any amendment, modification, termination,
waiver or consent effected in accordance with this Section 10.5 shall be binding
upon each Lender at the time outstanding, each future Lender and, if signed by a
Credit Party, on such Credit Party.

     10.6. Successors and Assigns; Participations.

     (a) This Agreement shall be binding upon the parties hereto and their
respective successors and assigns and shall inure to the benefit of the parties
hereto and the successors and assigns of Lenders. No Credit Party's rights or
obligations hereunder nor any interest therein may be assigned or delegated by
any Credit Party without the prior written consent of all Lenders.

     (b) Company, Administrative Agent and Lenders shall deem and treat the
Persons listed as Lenders in the Register as the holders and owners of the
corresponding Commitments and Loans listed therein for all purposes hereof, and
no assignment or transfer of any such Commitment or Loan shall be effective, in
each case, unless and until an Assignment Agreement effecting the assignment or
transfer thereof shall have been delivered to and accepted by Administrative
Agent and recorded in the Register as provided in Section 10.6(e). Prior to such
recordation, all amounts owed with respect to the applicable Commitment or Loan
shall be owed to the Lender listed in the Register as the owner thereof, and any
request, authority or consent of any Person who, at the time of making such
request or giving such authority or consent, is listed in the Register as a
Lender shall be conclusive and binding on any subsequent holder, assignee or
transferee of the corresponding Commitments or Loans.

     (c) Each Lender shall have the right at any time to sell, assign or
transfer all or

<PAGE>

a portion of its rights and obligations under this Agreement, including, without
limitation, all or a portion of its Commitment or Loans owing to it, Note or
Notes held by it, or other Obligation (provided, however, that each such
assignment shall be of a uniform, and not varying, percentage of all rights and
obligations under and in respect of every Loan and its related Commitments):

          (i) to any Person meeting the criteria of clause (i) of the definition
     of the term of "Eligible Assignee" upon the giving of notice to Company and
     Administrative Agent; and

          (ii) to any Person meeting the criteria of clause (ii) or (iii) of the
     definition of the term of "Eligible Assignee" and, in the case of
     assignments of Revolving Loans or Revolving Credit Commitments to any such
     Person (except in the case of assignments made by or to GSCP), consented to
     by each of Company and Administrative Agent (such consent not to be
     unreasonably withheld or delayed or, in the case of Company, required at
     any time an Event of Default shall have occurred and then be continuing);
     provided further, each such assignment pursuant to this Section 10.6(c)(ii)
     shall be in an aggregate amount of not less than (A) $5,000,000 (or such
     lesser amount as may be agreed to by Company and Administrative Agent or as
     shall constitute the aggregate amount of the Revolving Credit Commitments,
     Revolving Loans, Tranche A Term Loan Commitment and/or Tranche A Term
     Loans, as applicable, of the assigning Lender) with respect to the
     assignment of the Revolving Credit Commitments, Revolving Loans, Tranche A
     Term Loan Commitment and/or Tranche A Term Loans and (B) $1,000,000 (or
     such lesser amount as may be agreed to by Company and Administrative Agent
     or as shall constitute the aggregate amount of the Tranche B Term Loan of
     the assigning Lender) with respect to the assignment of the Tranche B Term
     Loans, and after giving effect to each such assignment pursuant to this
     Section 10.6(c)(ii) and unless otherwise agreed by Company and
     Administrative Agent, such Lender subject to clause (A) above shall have
     outstanding Commitments and Loans aggregating at least $5,000,000 and such
     Lender subject to clause (B) above shall have outstanding Loans aggregating
     at least $1,000,000 (or, in either case, such lesser amount as shall
     constitute the aggregate amount of the Tranche A Term Loan or Tranche B
     Term Loan, as applicable, of the assigning Lender) .

     (d) The assigning Lender and the assignee thereof shall execute and deliver
to Administrative Agent an Assignment Agreement, together with (i) a processing
and recordation fee of $3,500 (except that only one fee shall be payable in the
case of contemporaneous assignments to Related Funds), and (ii) such forms,
certificates or other evidence, if any, with respect to United States federal
income tax withholding matters as the assignee under such Assignment Agreement
may be required to deliver to Administrative Agent pursuant to Section 2.18(c).

     (e) Upon its receipt of a duly executed and completed Assignment Agreement,
together with the processing and recordation fee referred to in Section 10.6(d)
(and any forms, certificates or other evidence required by this Agreement in
connection therewith), Administrative

<PAGE>

Agent shall record the information contained in such Assignment Agreement in the
Register, shall give prompt notice thereof to Company and shall maintain a copy
of such Assignment Agreement.

     (f) Each Lender, upon execution and delivery hereof or upon executing and
delivering an Assignment Agreement, as the case may be, represents and warrants
as of the Closing Date or as of the applicable Effective Date (as defined in the
applicable Assignment Agreement) that (i) it is an Eligible Assignee; (ii) it
has experience and expertise in the making of or investing in commitments or
loans such as the applicable Revolving Credit Commitments or Loans, as the case
may be; and (iii) it will make or invest in, as the case may be, its Revolving
Credit Commitments or Loans for its own account in the ordinary course of its
business and without a view to distribution of such Revolving Credit Commitments
or Loans within the meaning of the Securities Act or the Exchange Act or other
federal securities laws (it being understood that, subject to the provisions of
this Section 10.6, the disposition of such Revolving Credit Commitments or Loans
or any interests therein shall at all times remain within its exclusive
control).

     (g) Subject to the terms and conditions of this Section 10.6, as of the
"Effective Date" specified in the applicable Assignment Agreement: (i) the
assignee thereunder shall have the rights and obligations of a "Lender"
hereunder to the extent such rights and obligations hereunder have been assigned
to it pursuant to such Assignment Agreement and shall thereafter be a party
hereto and a "Lender" for all purposes hereof; (ii) the assigning Lender
thereunder shall, to the extent that rights and obligations hereunder have been
assigned thereby pursuant to such Assignment Agreement, relinquish its rights
(other than any rights which survive the termination hereof under Section 10.8)
and be released from its obligations hereunder (and, in the case of an
Assignment Agreement covering all or the remaining portion of an assigning
Lender's rights and obligations hereunder, such Lender shall cease to be a party
hereto; provided, anything contained in any of the Credit Documents to the
contrary notwithstanding, and (y) such assigning Lender shall continue to be
entitled to the benefit of all indemnities hereunder as specified herein with
respect to matters arising out of the prior involvement of such assigning Lender
as a Lender hereunder; (iii) the Commitments shall be modified to reflect the
Commitment of such assignee and any remaining Commitment of such assigning
Lender, if any; and (iv) if any such assignment occurs after the issuance of any
Note hereunder, the assigning Lender shall, upon the effectiveness of such
assignment or as promptly thereafter as practicable, surrender its applicable
Notes to Administrative Agent for cancellation, and thereupon Company shall
issue and deliver new Notes, if so requested by the assignee and/or assigning
Lender, to such assignee and/or to such assigning Lender, with appropriate
insertions, to reflect the new Commitments and/or outstanding Loans of the
assignee and/or the assigning Lender.

     (h) Each Lender shall have the right at any time to sell one or more
participations to any Person (other than Company, any of its Subsidiaries or any
of its Affiliates) in all or any part of its Commitments, Loans or in any other
Obligation. The holder of any such participation, other than an Affiliate of the
Lender granting such participation, shall not be entitled to require such Lender
to take or omit to take any action hereunder except with respect to any
amendment modification or waiver that would (i) extend the final scheduled
maturity of any Loan,

<PAGE>

Note in which such participant is participating, or reduce the rate or extend
the time of payment of Interest or Fees thereon (except in connection with a
waiver of applicability of any post-default increase in interest rates) or
reduce the principal amount thereof, or increase the amount of the participant's
participation over the amount thereof then in effect (it being understood that a
waiver of any Default or Event of Default or of a mandatory reduction in the
Commitment shall not constitute a change in the terms of such participation, and
that an increase in any Commitment or Loan shall be permitted without the
consent of any participant if the participant's participation is not increased
as a result thereof), (ii) consent to the assignment or transfer by any Credit
Party of any of its rights and obligations under this Agreement or (iii) release
all or substantially all of the Collateral under the Collateral Documents
(except as expressly provided in the Credit Documents) supporting the Loans
hereunder in which such participant is participating. All amounts payable by any
Credit Party hereunder, including amounts payable to such Lender pursuant to
Section 2.16(c), 2.17 or 2.18, shall be determined as if such Lender had not
sold such participation. Each Credit Party and each Lender hereby acknowledge
and agree that, solely for purposes of Sections 2.15 and 10.4, (1) any
participation will give rise to a direct obligation of each Credit Party to the
participant and (2) the participant shall be considered to be a "Lender."

     (i) In addition to any other assignment permitted pursuant to this Section
10.6, (i) any Lender may assign and pledge all or any portion of its Loans, the
other Obligations owed to such Lender, and its Notes, if any, to any Federal
Reserve Bank as collateral security pursuant to Regulation A of the Board of
Governors of the Federal Reserve System and any operating circular issued by
such Federal Reserve Bank, and (ii) any Lender which is an investment fund may
pledge all or any portion of its Notes, if any, or Loans to any trustee for, or
any other representative of, holders of obligations owed, or securities issued,
by such fund (provided that such trustee or other representative is an Eligible
Assignee), as security for such obligations or securities; provided no Lender,
as between Company and such Lender, shall be relieved of any of its obligations
hereunder as a result of any such assignment and pledge, and provided further in
no event shall the applicable Federal Reserve Bank or trustee or other
representative be considered to be a "Lender" or be entitled to require the
assigning Lender to take or omit to take any action hereunder.

     10.7. Independence of Covenants. All covenants hereunder shall be given
independent effect so that if a particular action or condition is not permitted
by any of such covenants, the fact that it would be permitted by an exception
to, or would otherwise be within the limitations of, another covenant shall not
avoid the occurrence of a Default or an Event of Default if such action is taken
or condition exists.

     10.8. Survival of Representations, Warranties and Agreements. All
representations, warranties and agreements made herein shall survive the
execution and delivery hereof and the making of any Credit Extension.
Notwithstanding anything herein or implied by law to the contrary, the
agreements of each Credit Party set forth in Sections 2.16(c), 2.17, 2.18, 10.2,
10.3 and 10.4 and the agreements of Lenders set forth in Sections 2.15 and 9.6
shall survive the payment of the Loans and the termination hereof.

<PAGE>

     10.9. No Waiver; Remedies Cumulative. No failure or delay on the part of
Administrative Agent or any Lender in the exercise of any power, right or
privilege hereunder or under any other Credit Document shall impair such power,
right or privilege or be construed to be a waiver of any default or acquiescence
therein, nor shall any single or partial exercise of any such power, right or
privilege preclude other or further exercise thereof or of any other power,
right or privilege. The rights, powers and remedies given to each Agent and each
Lender hereby are cumulative and shall be in addition to and independent of all
rights, powers and remedies existing by virtue of any statute or rule of law or
in any of the other Credit Documents or any of the Hedge Agreements. Any
forbearance or failure to exercise, and any delay in exercising, any right,
power or remedy hereunder shall not impair any such right, power or remedy or be
construed to be a waiver thereof, nor shall it preclude the further exercise of
any such right, power or remedy.

     10.10. Marshalling; Payments Set Aside. Neither Administrative Agent nor
any Lender shall be under any obligation to marshal any assets in favor of any
Credit Party or any other Person or against or in payment of any or all of the
Obligations. To the extent that any Credit Party makes a payment or payments to
Administrative Agent or Lenders (or to Administrative Agent, on behalf of
Lenders), or Administrative Agent or Lenders enforce any security interests or
exercise their rights of setoff, and such payment or payments or the proceeds of
such enforcement or setoff or any part thereof are subsequently invalidated,
declared to be fraudulent or preferential, set aside and/or required to be
repaid to a trustee, receiver or any other party under any bankruptcy law, any
other state or federal law, common law or any equitable cause, then, to the
extent of such recovery, the obligation or part thereof originally intended to
be satisfied, and all Liens, rights and remedies therefor or related thereto,
shall be revived and continued in full force and effect as if such payment or
payments had not been made or such enforcement or setoff had not occurred.

     10.11. Severability. In case any provision in or obligation hereunder or
any Note shall be invalid, illegal or unenforceable in any jurisdiction, the
validity, legality and enforceability of the remaining provisions or
obligations, or of such provision or obligation in any other jurisdiction, shall
not in any way be affected or impaired thereby.

     10.12. Obligations Several; Independent Nature of Lenders' Rights. The
obligations of Lenders hereunder are several and no Lender shall be responsible
for the obligations or Commitment of any other Lender hereunder. Nothing
contained herein or in any other Credit Document, and no action taken by Lenders
pursuant hereto or thereto, shall be deemed to constitute Lenders as a
partnership, an association, a joint venture or any other kind of entity. The
amounts payable at any time hereunder to each Lender shall be a separate and
independent debt, and each Lender shall be entitled to protect and enforce its
rights arising hereunder and it shall not be necessary for any other Lender to
be joined as an additional party in any proceeding for such purpose.

     10.13. Headings. Section headings herein are included herein for
convenience of reference only and shall not constitute a part hereof for any
other purpose or be given any substantive effect.

<PAGE>

     10.14. APPLICABLE LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE
PARTIES HEREUNDER SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK (INCLUDING SECTION 5-1401 OF
THE GENERAL OBLIGATIONS LAW OF THE STATE OF NEW YORK), BUT OTHERWISE WITHOUT
REGARD TO CONFLICT OF LAWS PRINCIPLES THEREOF.

     10.15. CONSENT TO JURISDICTION. ALL JUDICIAL PROCEEDINGS BROUGHT AGAINST
ANY CREDIT PARTY ARISING OUT OF OR RELATING HERETO OR ANY OTHER CREDIT DOCUMENT,
OR ANY OF THE OBLIGATIONS, MAY BE BROUGHT IN ANY STATE OR FEDERAL COURT OF
COMPETENT JURISDICTION IN THE STATE, COUNTY AND CITY OF NEW YORK. BY EXECUTING
AND DELIVERING THIS AGREEMENT, EACH CREDIT PARTY, FOR ITSELF AND IN CONNECTION
WITH ITS PROPERTIES, IRREVOCABLY (a) ACCEPTS GENERALLY AND UNCONDITIONALLY THE
NONEXCLUSIVE JURISDICTION AND VENUE OF SUCH COURTS; (b) WAIVES ANY DEFENSE OF
FORUM NON CONVENIENS; (c) AGREES THAT SERVICE OF ALL PROCESS IN ANY SUCH
PROCEEDING IN ANY SUCH COURT MAY BE MADE BY REGISTERED OR CERTIFIED MAIL, RETURN
RECEIPT REQUESTED, TO THE APPLICABLE CREDIT PARTY AT ITS ADDRESS PROVIDED IN
ACCORDANCE WITH SECTION 10.1; (d) AGREES THAT SERVICE AS PROVIDED IN CLAUSE (c)
ABOVE IS SUFFICIENT TO CONFER PERSONAL JURISDICTION OVER THE APPLICABLE CREDIT
PARTY IN ANY SUCH PROCEEDING IN ANY SUCH COURT, AND OTHERWISE CONSTITUTES
EFFECTIVE AND BINDING SERVICE IN EVERY RESPECT; AND (e) AGREES SUCH LENDERS
RETAIN THE RIGHT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO
BRING PROCEEDINGS AGAINST ANY CREDIT PARTY IN THE COURTS OF ANY OTHER
JURISDICTION.

     10.16. WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY AGREES TO
WAIVE ITS RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION
BASED UPON OR ARISING HEREUNDER OR UNDER ANY OF THE OTHER CREDIT DOCUMENTS OR
ANY DEALINGS BETWEEN THEM RELATING TO THE SUBJECT MATTER OF THIS LOAN
TRANSACTION OR THE LENDER/BORROWER RELATIONSHIP THAT IS BEING ESTABLISHED. THE
SCOPE OF THIS WAIVER IS INTENDED TO BE ALL-ENCOMPASSING OF ANY AND ALL DISPUTES
THAT MAY BE FILED IN ANY COURT AND THAT RELATE TO THE SUBJECT MATTER OF THIS
TRANSACTION, INCLUDING CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS AND
ALL OTHER COMMON LAW AND STATUTORY CLAIMS. EACH PARTY HERETO ACKNOWLEDGES THAT
THIS WAIVER IS A MATERIAL INDUCEMENT TO ENTER INTO A BUSINESS RELATIONSHIP, THAT
EACH HAS ALREADY RELIED ON THIS WAIVER IN ENTERING INTO THIS AGREEMENT,

<PAGE>

AND THAT EACH WILL CONTINUE TO RELY ON THIS WAIVER IN ITS RELATED FUTURE
DEALINGS. EACH PARTY HERETO FURTHER WARRANTS AND REPRESENTS THAT IT HAS REVIEWED
THIS WAIVER WITH ITS LEGAL COUNSEL AND THAT IT KNOWINGLY AND VOLUNTARILY WAIVES
ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL. THIS WAIVER IS
IRREVOCABLE, MEANING THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING
(OTHER THAN BY A MUTUAL WRITTEN WAIVER SPECIFICALLY REFERRING TO THIS SECTION
10.16 AND EXECUTED BY EACH OF THE PARTIES HERETO), AND THIS WAIVER SHALL APPLY
TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS HERETO OR
ANY OF THE OTHER CREDIT DOCUMENTS OR TO ANY OTHER DOCUMENTS OR AGREEMENTS
RELATING TO THE LOANS MADE HEREUNDER. IN THE EVENT OF LITIGATION, THIS AGREEMENT
MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT.

     10.17. Confidentiality. Each Lender shall hold all non-public information
obtained pursuant to the requirements hereof which has been identified as
confidential by Company in accordance with such Lender's customary procedures
for handling confidential information of this nature and in accordance with
prudent lending or investing practices, it being understood and agreed by
Company that in any event a Lender may make disclosures to Affiliates of such
Lender (and to other persons authorized by a Lender or Agent to organize,
present or disseminate such information in connection with disclosures otherwise
made in accordance with this Section 10.17) or disclosures reasonably required
by any bona fide or potential assignee, transferee or participant in connection
with the contemplated assignment, transfer or participation by such Lender of
any Loans or any participations `therein or by any direct or indirect
contractual counterparties (or the professional advisors thereto) in Hedge
Agreements (provided, such counterparties and advisors are advised of and agree
to be bound by the provisions of this Section 10.17) or disclosures required or
requested by any governmental agency or representative thereof or by the NAIC or
pursuant to legal process; provided, unless specifically prohibited by
applicable law or court order, each Lender shall make reasonable efforts to
notify Company of any request by any governmental agency or representative
thereof (other than any such request in connection with any examination of the
financial condition or other routine examination of such Lender by such
governmental agency) for disclosure of any such non-public information prior to
disclosure of such information.

     10.18. Usury Savings Clause. Notwithstanding any other provision herein,
the aggregate interest rate charged with respect to any of the Obligations,
including all charges or fees in connection therewith deemed in the nature of
interest under applicable law shall not exceed the Highest Lawful Rate. If the
rate of interest (determined without regard to the preceding sentence) under
this Agreement at any time exceeds the Highest Lawful Rate, the outstanding
amount of the Loans made hereunder shall bear interest at the Highest Lawful
Rate until the total amount of interest due hereunder equals the amount of
interest which would have been due

<PAGE>

hereunder if the stated rates of interest set forth in this Agreement had at all
times been in effect. In addition, if when the Loans made hereunder are repaid
in full the total interest due hereunder (taking into account the increase
provided for above) is less than the total amount of interest which would have
been due hereunder if the stated rates of interest set forth in this Agreement
had at all times been in effect, then to the extent permitted by law, Company
shall pay to Administrative Agent an amount equal to the difference between the
amount of interest paid and the amount of interest which would have been paid if
the Highest Lawful Rate had at all times been in effect. Notwithstanding the
foregoing, it is the intention of Lenders and Company to conform strictly to any
applicable usury laws. Accordingly, if any Lender contracts for, charges, or
receives any consideration which constitutes interest in excess of the Highest
Lawful Rate, then any such excess shall be cancelled automatically and, if
previously paid, shall at such Lender's option be applied to the outstanding
amount of the Loans made hereunder or be refunded to Company.

     10.19. Counterparts; Effectiveness. This Agreement may be executed in any
number of counterparts, each of which when so executed and delivered shall be
deemed an original, but all such counterparts together shall constitute but one
and the same instrument. This Agreement shall become effective upon the
execution of a counterpart hereof by each of the parties hereto and receipt by
Company and Administrative Agent of written or telephonic notification of such
execution and authorization of delivery thereof.
