requested by the Borrower in

                                       32

further, that no Letter of Credit shall require payment against a conforming
- -------
draft to be made thereunder on the following Domestic Business Day that such
draft is presented if such presentation is made later than 10:00 A.M. New York
City time (except that if the beneficiary of any Letter of Credit requests at
the time of the issuance of its Letter of Credit that payment be made on the
same Domestic Business Day against a conforming draft, such beneficiary

shall be entitled to such a same day draw, provided such draft is presented to
the applicable Fronting Bank no later than 10:00 A.M. New York City time and
provided further the Borrower shall have requested to the Fronting Bank and the
Administrative Agent that such beneficiary shall be entitled to a same day
draw). In determining whether to pay on such Letter of Credit, the Fronting Bank

Bank's Designated Lender (if any) as provided in Section 9.6(d); however such
Bank shall not be required to specify in its Money Market Quote whether such
Money Market Loans will be funded by such Designated Lender.

notify the Borrower (x) with respect to each Money Market Quote submitted in
accordance with subsection (d), of the terms of such Money Market Quote and the
identity of the Bank submitting such Money Market Quote and (y) of any Money
Market Quote that amends, modifies or is otherwise inconsistent with a previous
Money Market Quote submitted by such Bank with respect to the same Money Market
Quote Request. Any such subsequent Money Market Quote shall be disregarded by
the Administrative Agent unless such subsequent Money Market Quote is submitted
solely to correct a manifest error in such former Money Market Quote. The
Administrative Agent's notice to the Borrower shall specify (A) the aggregate
principal amount of Money Market Loans for which offers have been received for
each Interest Period specified in the related Money Market Quote Request, (B)
the respective principal amounts and Money Market Margins or Money Market

          (f    Acceptance and Notice by Borrower. Not later than 1:00 p.m. (New
                ---------------------------------
York City time) on (x) the third Euro-Dollar Business Day prior to the proposed
date of Borrowing, in the case of a LIBOR Auction, or (y) the proposed date of
Borrowing, in the case of an Absolute Rate Auction (or, in either case, such
other time or date as the Borrower and the Administrative Agent shall have
mutually agreed and shall have notified to the Banks not later than the date of
the Money Market Quote Request for the first LIBOR Auction or Absolute Rate
Auction for which such change is to be

effective), the Borrower shall notify the Administrative Agent of its acceptance
or non-acceptance of the offers so notified to it pursuant to subsection (e). In
the case of acceptance, such notice (a "Notice of Money Market Borrowing") shall
                                        --------------------------------
specify the aggregate principal amount of offers for each Interest Period that
are accepted. The Borrower may accept any Money Market Quote in whole or in
part; provided that:
      --------

               (i)   the aggregate principal amount of each Money Market
     Borrowing may not exceed the applicable amount set forth in the related
     Money Market Quote Request;

               (ii)  the principal amount of each Money Market Borrowing must be
     $10,000,000 or a larger multiple of $500,000;

               (iii) acceptance of offers may only be made on the basis of
     ascending Money Market Margins or Money Market Absolute Rates, as the case
     may be; and

               (iv)  the Borrower may not accept any offer that is described in
     subsection (d)(iii) or that otherwise fails to comply with the requirements
     of this Agreement.

          (g   Allocation by Administrative Agent. If offers are made by two or
               ----------------------------------
more Banks with the same Money Market Margins or Money Market Absolute Rates, as
the case may be, for a greater aggregate principal amount than the amount in
respect of which such offers are accepted for the related Interest Period, the
principal amount of Money Market Loans in respect of which such offers are
accepted shall be allocated by the Administrative Agent among such Banks as
nearly as possible (in multiples of $500,000, as the Administrative Agent may
deem appropriate) in proportion to the aggregate principal amounts of such
offers. Determinations by the Administrative Agent of the amounts of Money
Market Loans shall be conclusive in the absence of manifest error.

          (h   Notification by Administrative Agent. Upon receipt of the
               ------------------------------------
Borrower's Notice of Money Market Borrowing in accordance with Section 2.3(f)
hereof, the Administrative Agent shall, on the date such Notice of Money Market
Borrowing is received by the Administrative Agent, notify each Bank of the
principal amount of the Money Market Borrowing accepted by the Borrower and of
such Bank's share (if any) of

                                       38



such Money Market Borrowing and such Notice of Money Market Borrowing shall not
thereafter be revocable by the Borrower. A Bank who is notified that it has been
selected to make a Money Market Loan may designate its Designated Lender (if
any) to fund such Money Market Loan on its behalf, as described in Section
9.6(d). Any Designated Lender which funds a Money Market Loan shall on and after
the time of such funding become the obligee under such Money Market Loan and be
entitled to receive payment thereof when due. No Bank shall be relieved of its
obligation to fund a Money Market Loan, and no Designated Lender shall assume
such obligation, prior to the time the applicable Money Market Loan is funded.

          Section II.4. Notice to Banks; Funding of Loans.
                        ---------------------------------

          (a Upon receipt of a Notice of Committed Borrowing, the Administrative
Agent shall notify each Bank on the same day as it receives the Notice of
Committed Borrowing of the contents thereof and of such Bank's share of such
Borrowing and such Notice of Committed Borrowing shall not thereafter be
revocable by the Borrower.

          (b Not later than 2:00 P.M. (New York City time) on the date of each
Committed Borrowing, each Bank shall make available its share of such Committed
Borrowing, in Federal or other funds immediately available in New York City, to
the Administrative Agent at its address referred to in Section 9.1. The
Administrative Agent will make the funds so received from the Banks available to
the Borrower at the Administrative Agent's aforesaid address. If the Borrower
has requested the issuance of a Letter of Credit, no later than 12:00 Noon (New
York City time) on the date of such issuance as indicated in the notice
delivered pursuant to Section 2.2(b), the Fronting Bank shall issue such Letter
of Credit in the amount so requested and deliver the same to the Borrower with a
copy thereof to the Administrative Agent. At the request of any Bank, the
Administrative Agent promptly shall deliver copies thereof to such Bank.
Immediately upon the issuance of each Letter of Credit by the Fronting Bank,
such Fronting Bank shall be deemed to have sold and transferred to each other
Bank, and each such other Bank shall be deemed, and hereby agrees, to have
irrevocably and unconditionally purchased and received from the Fronting Bank,
without recourse or warranty, an undivided interest and a participation in such
Letter of Credit, any drawing thereunder, and the obligations of the Borrower
hereunder with respect thereto, and any security therefor or guaranty pertaining
thereto, in an amount equal to such Bank's ratable

                                       39



share thereof (based upon the ratio its Commitment bears to the aggregate of all
Commitments). Upon any change in any of the Commitments in accordance herewith,
there shall be an automatic adjustment to such participations to reflect such
changed shares. The Fronting Bank shall have the primary obligation to fund any
and all draws made with respect to such Letter of Credit notwithstanding any
failure of a participating Bank to fund its ratable share of any such draw.
Unless the Administrative Agent determines that any applicable condition
specified in Article III has not been satisfied, the Administrative Agent will
instruct the Fronting Bank to make such Letter of Credit available to the
Borrower and the Fronting Bank shall make such Letter of Credit available to the
Borrower at the Borrower's aforesaid address or at such address in the United
States as Borrower shall request on the date of the Borrowing.

          (c Unless the Administrative Agent shall have received notice from a
Bank prior to the date of any Borrowing that such Bank will not make available
to the Administrative Agent such Bank's share of such Borrowing, the
Administrative Agent may assume that such Bank has made such share available to
the Administrative Agent on the date of such Borrowing in accordance with
subsection (b) of this Section 2.4 and the Administrative Agent may, in reliance
upon such assumption, make available to the Borrower on such date a
corresponding amount. If and to the extent that such Bank shall not have so made
such share available to the Administrative Agent, such Bank and the Borrower
severally agree to repay to the Administrative Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the date
such amount is made available to the Borrower until the date such amount is
repaid to the Administrative Agent, at (i) in the case of the Borrower, a rate
per annum equal to the higher of the Federal Funds Rate and the interest rate
applicable thereto pursuant to Section 2.7 and (ii) in the case of such Bank,
the Federal Funds Rate. If such Bank shall repay to the Administrative Agent
such corresponding amount, such amount so repaid shall constitute such Bank's
Loan included in such Borrowing for purposes of this Agreement.

          Section II.5. Notes.
                        -----

          (a The Loans shall be evidenced by the Notes, each of which shall be
payable to the order of each Bank for the account of its Applicable Lending
Office in an amount equal to each such Bank's Commitment.

          (b   Each Bank may, by notice to the Borrower and the Administrative
Agent, request that its Loans of a particular type be evidenced by a separate
Note in an amount equal to the aggregate unpaid principal amount of such Bank's
Loans of such type. Each such Note shall be in substantially the form of Exhibit
                                                                         -------
A hereto, with appropriate modifications to reflect the fact that it evidences

solely Loans of the relevant type for such Bank. Each reference in this
Agreement to the "Note" of such Bank shall be deemed to refer to and include any
                  ----
or all of such Notes, as the context may require.

          (c   Upon receipt of each Bank's Note, the Administrative Agent shall
forward such Note to such Bank. Each Bank shall record the date, amount, type
and maturity of each Loan made by it and the date and amount of each payment of
principal made by the Borrower with respect thereto, and may, if such Bank so
elects in connection with any transfer or enforcement of its Note, endorse on
the schedule forming a part thereof appropriate notations to evidence the
foregoing information with respect to each such Loan then outstanding; provided
                                                                       --------

points plus the Base Rate for such day. Such interest shall be payable for each
Interest Period on the last day thereof.

          (b   Each Euro-Dollar Loan shall bear interest on the outstanding
principal amount thereof, for each day during the Interest Period applicable
thereto, at a

Reserve System in New York City with deposits exceeding five billion dollars in
respect of "Eurocurrency liabilities" (or in respect of any other category of
liabilities which includes deposits by reference to which the interest rate on
Euro-Dollar Loans is determined or any category of extensions of credit or other
assets which includes loans by a non-United States office of any Bank to United
States residents). The Adjusted London Interbank Offered Rate shall be adjusted

               --------------
interest rate is to be determined, two (2) Euro-Dollar Business Days before the
first day of that period, unless market practice differs in the relevant
interbank market

                                       42



for a currency, in which case the Quotation Date for that currency will be
determined by the Administrative Agent in accordance with market practice in the
London interbank market (and if quotations would normally be given by leading
banks in the London interbank market on more than one day, the Quotation Date
will be the last of those days).

          "Telerate Page 3740 or Page 3750" means the display designated as

interest on the outstanding principal amount thereof, for the Interest Period
applicable thereto, at a rate per annum equal to the sum of the London Interbank
Offered Rate for such Interest Period (determined in accordance with Section
2.7(b) as if the related Money Market LIBOR Borrowing were a Committed
Euro-Dollar Borrowing) plus (or minus) the Money Market Margin quoted by the
Bank making such Loan in accordance with Section 2.3. Each Money Market Absolute
Rate Loan shall bear interest on the outstanding principal amount thereof, for
the Interest Period applicable thereto, at a rate per annum equal to the Money
Market Absolute Rate quoted by the Bank making such Loan in accordance with
Section 2.3. Such interest shall be payable for each Interest Period on the last

Administrative Agent for the account of the Banks ratably in proportion to their
respective Commitments, a commitment fee on the daily average undrawn and
uncancelled Commitments in any given quarter at the respective percentages per
annum based upon the range into which the Total Debt Ratio then falls in
accordance with the following table:



- --------------------------------------------------- -------------------------------------------------
                                                    Applicable Commitment Fee (% per

The commitment/facility fee shall be payable quarterly, in arrears, on each
January 1, April 1, July 1, and October 1 during the Term and any extensions
thereof. Any change in the Borrower's Credit Rating causing it to move into a
different range on the table shall effect an immediate change in the applicable
percentage per annum. In the event that the Borrower's (or the General
Partner's) Credit Rating is such that the Rating Agencies' ratings are split
between a higher and a lower rating, the applicable percentage per annum shall
be based upon the lower of such two (2) Credit Ratings. In the event that
Borrower (or, as applicable, the General Partner) receives more than two (2)
credit ratings and such credit ratings are not equivalent, the applicable fee
shall be determined by the lower of the two (2) highest ratings, provided that
each of said two (2) highest ratings shall be Investment Grade Ratings and at
least one of which shall be an Investment Grade Rating from S&P or Moody's. In
the event that such two ratings are more than one rating apart, the Applicable
Margin will be determined based on the rating which is one rating above the
lower of the two ratings.

          (b   Letter of Credit Fee. During the Term, the Borrower shall pay to
               --------------------
the Administrative Agent, for the account of the Banks in proportion to their

respect to Euro-Dollar Loans on the daily average of such issued and undrawn
Letters of Credit, which fee shall be payable, in arrears, on each January 1,
April 1, July 1 and October 1 during the Term. From the

                                       45



occurrence, and during the continuance, of an Event of Default, such fee shall
be increased to be equal to four percent (4%) per annum on the daily average of
such issued and undrawn Letters of Credit.

          (c   Fronting Bank Fee. The Borrower shall pay any Fronting Bank, for
               -----------------

addition to and not in lieu of, the Letter of Credit Fee. The Fronting Bank Fee
shall be payable in arrears on each January 1, April 1, July 1 and October 1

pay such fees in accordance with the provisions hereof shall be binding upon the
Borrower and shall inure to the benefit of the Administrative Agent and the
Banks regardless of whether any Loans are actually made.

                         ---------------------                 ----
Commitments shall terminate and expire, and the Borrower shall return or cause
to be returned all Letters of Credit to the Fronting Bank, on March 15, 2005

          Section II.10. Mandatory Prepayment.
                         --------------------

Separate Parcel that originally formed a part of an Unencumbered Asset Pool
Property) is sold, transferred or released from the restrictions of Section 5.16
hereof, the Borrower shall, simultaneously with such sale, transfer or release,
prepay the Loans in an amount equal to 100% of the net proceeds of such sale or
transfer, in the event of a sale or transfer, or such lesser amount as shall be
required for the Borrower to remain in compliance with this Agreement, in the
event of such a sale, transfer or release. Notwithstanding the foregoing, a
simultaneous like-kind exchange under Section 1031 of the Internal Revenue Code
will not be subject to the provisions of this Section 2.10(a), provided that the
exchanged property has qualified as a New Acquisition and any cash "boot"
associated therewith shall be applied to prepayment of the Loans or such lesser
amount of such cash "boot" as shall be required for the Borrower to remain in
compliance with this Agreement. Sale of an Unencumbered Asset Pool Property (or
any Separate

                                       46



Parcel that originally formed a part of a Unencumbered Asset Pool Property) in
violation of this Section 2.10 shall constitute an Event of Default.

          (b   Simultaneously with the closing of any sale of common shares of
beneficial interest, preferred shares of beneficial interest, partnership
interests, limited liability company interests, or other ownership or equity
interests in the Borrower or the General Partner, the Borrower shall,
simultaneously with such sale, prepay the Loans in an amount equal to 100% of
the Net Offering Proceeds. Notwithstanding the foregoing, however, in the event
that (i) the Net Offering Proceeds in connection with any individual offering
shall be less than $20,000,000, and the Borrower anticipates reinvesting the
same in Real Property Assets within fifteen (15) days after receipt thereof or
(ii) any Loans expire within thirty (30) days of the date thereof, the Borrower
may retain such funds, provided, however, that if the Borrower shall not in fact
so reinvest such funds in Real Property Assets within such fifteen (15) day
period or repay such Loans within such thirty (30) day period, as the case may
be, the Borrower shall immediately apply the same in repayment of the Loans.

          (c   In the event that the Unsecured Debt Ratio is not maintained as
of the last day of a calendar quarter, either (i) the Borrower will add a Real
Property Asset to the Unencumbered Asset Pool Properties in accordance with this
Agreement which, on a pro forma basis (i.e. the Unsecured Debt Ratio shall be
                      ---------        ---
recalculated to include such Real Property Asset as though the same had been an
Unencumbered Asset Pool Property for the entire applicable period) would result
in compliance with the Unsecured Debt Ratio, or (ii) the Borrower shall prepay
to the Administrative Agent, for the account of the Banks, an amount necessary
to cause the Unsecured Debt Ratio to be in compliance within ninety (90) days of
the date on which the Unsecured Debt Ratio failed to be maintained. Failure by
the Borrower to comply with the Unsecured Debt Ratio within ninety (90) days of
the date of such non-compliance shall be an Event of Default.

          Section II.11. Optional Prepayments.
                         --------------------

          (a   The Borrower may, upon at least one Domestic Business Day's
notice to the Administrative Agent, prepay to the Administrative Agent, for the
account of the Banks, any Base Rate Borrowing in whole at any time, or from time
to time in part in amounts aggregating One Million Dollars ($1,000,000), or an
integral multiple of One Million Dollars ($1,000,000) in excess thereof or, if
less, the outstanding principal balance, by paying the principal amount to be
prepaid together with accrued interest

                                       47

applied to prepay ratably the Loans of the several Banks included in such
Borrowing.

          (b   Except as provided in Section 8.2, the Borrower may not prepay
all or any portion of the principal amount of any Euro-Dollar Loan prior to the
maturity thereof unless the Borrower shall also pay any applicable expenses
pursuant to Section 2.13. Any such prepayment shall be upon at least three (3)
Euro-Dollar Business Days' notice to the Administrative Agent. Any notice of
prepayment delivered pursuant to this Section 2.11(b) shall set forth the amount
of such prepayment which is applicable to any Loan made for working capital
purposes. Each such optional prepayment shall be in the amounts set forth in
Section 2.11(a) above and shall be applied to prepay ratably the Loans of the
Banks included.

          (c   The Borrower may not prepay any Money Market Loan.

          (d   The Borrower may, upon at least one (1) Domestic Business Day's
notice to the Administrative Agent (by 2:00 p.m New York time on such Domestic
Business Day), reimburse the Administrative Agent for the benefit of the
Fronting Bank for the amount of any drawing under a Letter of Credit in whole or
in part in any amount.

to the Fronting Bank in whole, but not in part, and the Fronting Bank shall give
the Administrative Agent and each of the Banks notice of such return.

any part of the Commitments in amounts aggregating One Million Dollars

excess thereof, by the delivery to the Administrative Agent and the Banks of a
notice of cancellation upon at least three (3) Domestic Business Days' notice to
Administrative Agent and the Banks, whereupon, all or such portion of the
Commitments shall terminate as to the Banks, pro rata on the date set forth in

aggregate amount which exceeds the aggregate Commitments (after giving effect to
any such reduction), the Borrower shall prepay to the Administrative Agent, for
the account of the Banks, all or such portion of Loans outstanding on such date
in accordance with the requirements of Sections 2.11(a) and (b). In no event
shall the Borrower be permitted to cancel Commitments for which a Letter of
Credit has been issued and is outstanding unless the Borrower returns (or causes
to be returned) such

                                       48



Letter of Credit to the Fronting Bank. The Borrower shall be permitted to
designate in its notice of cancellation which Loans, if any, are to be prepaid.

          (g   Upon receipt of a notice of prepayment or cancellation or a
return of a Letter of Credit pursuant to this Section, the Administrative Agent
shall promptly, and in any event within one (1) Domestic Business Day, notify
each Bank of the contents thereof and of such Bank's ratable share (if any) of
such prepayment or cancellation and such notice shall not thereafter be
revocable by the Borrower.

          (h   Any amounts so prepaid pursuant to this Section 2.11 may be
reborrowed subject to the other terms of this Agreement. In the event that the
Borrower elects to cancel all or any portion of the Commitments pursuant to
Section 2.11(c) hereof, such cancellation shall be irrevocable and such amounts
may not be reborrowed.

          Section II.12. General Provisions as to Payments.
                         ---------------------------------

          (a   The Borrower shall make each payment of principal of, and
interest on, the Loans and of fees hereunder, not later than 3:00 p.m. (New York
City time) on the date when due, in Federal or other funds immediately available
in New York City, to the Administrative Agent at its address referred to in
Section 9.1. The Administrative Agent will distribute to each Bank its ratable
share of each such payment received by the Administrative Agent for the account
of the Banks on the same day as received by the Administrative Agent if received
by the Administrative Agent by 3:00 p.m. (New York City time), or, if received
by the Administrative Agent after 3:00 p.m. (New York City time), on the
immediately following Domestic Business Day. If the Administrative Agent shall
fail to distribute to a Bank its ratable share of a payment on the same day it
is received or the immediately following Domestic Business Day, as applicable in
accordance with the immediately preceding sentence, the Administrative Agent
shall pay to such Bank the interest accrued on such payment at the Federal Funds
Rate, commencing on the day the Administrative Agent should have made the
payment to such Bank and ending on the day prior to the date payment is actually
made. Whenever any payment of principal of, or interest on, the Base Rate Loans
or of fees shall be due on a day which is not a Domestic Business Day, the date
for payment thereof shall be extended to the next succeeding Domestic Business
Day. Whenever any payment of principal of, or interest on, the Euro-Dollar Loans
shall be due on a day which is not a Euro-Dollar Business Day, the date for
payment thereof shall be extended to the next succeeding Euro-Dollar Business
Day unless such Euro-Dollar Business Day falls in

                                       49



another calendar month, in which case the date for payment thereof shall be the
next preceding Euro-Dollar Business Day. If the date for any payment of
principal is extended by operation of law or otherwise, interest thereon shall
be payable for such extended time.

          (b   Unless the Administrative Agent shall have received notice from
the Borrower prior to the date on which any payment is due to the Banks
hereunder that the Borrower will not make such payment in full, the
Administrative Agent may assume that the Borrower has made such payment in full
to the Administrative Agent on such date and the Administrative Agent may, in
reliance upon such assumption, cause to be distributed to each Bank on such due
date an amount equal to the amount then due such Bank. If and to the extent that
the Borrower shall not have so made such payment, each Bank shall repay to the
Administrative Agent forthwith on demand such amount distributed to such Bank
together with interest thereon, for each day from the date such amount is
distributed to such Bank until the date such Bank repays such amount to the
Administrative Agent, at the Federal Funds Rate.

          (c   All payments made on the Notes shall be credited, to the extent
of the amount thereof, in the following manner: (a) first, against all costs,
expenses and other fees (including reasonable attorneys' fees) arising under the
terms hereof, of which, if no Event of Default shall have occurred and be
continuing, the Borrower has received notice pursuant to the terms hereof, (b)
second, against the amount of interest accrued and unpaid on the Notes as of the
date of such payment, (c) third, against all principal due and owing on the
Notes as of the date of such payment, and (d) fourth, to all other amounts
constituting any portion of the Obligations.

          Section II.13. Funding Losses. If the Borrower makes any payment of
                         --------------

principal with respect to any Euro-Dollar Loan (pursuant to Article II, VI or
VIII or otherwise, and specifically including any payments made pursuant to
Sections 2.10 or 2.11) on any day other than the last day of the Interest Period
applicable thereto, or if the Borrower fails to borrow any Euro-Dollar Loans,
after notice has been given to any Bank in accordance with Section 2.4(a), or to
prepay any Euro-Dollar Loans, after notice has been given to any Bank in
accordance with Section 2.11(b), the Borrower shall reimburse each Bank within
15 days after demand for any resulting loss or expense incurred by it (or by an
existing Participant in the related Loan; provided that no Participant shall be
entitled to receive more than the Bank, with respect to which such Participant
is a Participant, would be entitled to receive under this Section 2.13),
including (without

                                       50



limitation) any loss incurred in obtaining, liquidating or employing deposits
from third parties, but excluding loss of margin for the period after any such
payment or failure to borrow, provided that such Bank shall have delivered to
                              --------
the Borrower a certificate as to the amount of such loss or expense and the
calculation thereof, which certificate shall be conclusive in the absence of
manifest error.

          Section II.14. Computation of Interest and Fees. Interest based on the
                         --------------------------------
Prime Rate hereunder shall be computed on the basis of a year of 365 days (or
366 days in a leap year) and paid for the actual number of days elapsed
(including the first day but excluding the last day). All other interest and
fees shall be computed on the basis of a year of 360 days and paid for the
actual number of days elapsed (including the first day but excluding the last
day).

          Section II.15. Method of Electing Interest Rates.
                         ---------------------------------

          (a   The Loans included in each Borrowing shall bear interest
initially at the type of rate specified by the Borrower in the applicable Notice
of Committed Borrowing. Thereafter, the Borrower may from time to time elect to
change or continue the type of interest rate borne by each Group of Loans
(subject in each case to the provisions of Article VIII), as follows:

               (i)  if such Loans are Base Rate Loans, the Borrower may elect to
     convert such Loans to Euro-Dollar Loans as of any Euro-Dollar Business Day;

               (ii) if such Loans are Euro-Dollar Loans, the Borrower may elect
     to convert such Loans to Base Rate Loans or elect to continue such Loans as
     Euro-Dollar Loans for an additional Interest Period, in each case effective
     on the last day of the then current Interest Period applicable to such
     Loans.

Each such election shall be made by delivering a notice (a "Notice of Interest

Loans, in which case such notice shall be delivered to the Administrative Agent
no later than 2:00 p.m. (New York City time) at least one (1) Domestic Business
Day before such continuation is to be effective). A Notice of Interest Rate
Election may, if it so specifies, apply to only a portion of the aggregate
principal amount of the relevant Group of Loans; provided that (i) such portion

is allocated ratably among the Loans comprising such Group, (ii) the portion to
which such notice applies, and the remaining portion to which it does not apply,
are each $1,000,000 or any larger multiple of $1,000,000, (iii) there shall be
no more than ten (10) Borrowings comprised of Euro-Dollar Loans outstanding at
any time under this Agreement, (iv) no Loan may be continued as, or converted
into, a Euro-Dollar Loan when any Event of Default has occurred and is
continuing, and (v) no Interest Period shall extend beyond the Maturity Date.

          (b   Each Notice of Interest Rate Election shall specify:

               (i)   the Group of Loans (or portion thereof) to which such
     notice applies;

               (ii)  the date on which the conversion or continuation selected
     in such notice is to be effective, which shall comply with the applicable
     clause of subsection (a) above;

               (iii) if the Loans comprising such Group are to be converted, the
     new type of Loans and, if such new Loans are Euro-Dollar Loans, the

               (iv)  if such Loans are to be continued as Euro-Dollar Loans for
     an additional Interest Period, the duration of such additional Interest
     Period.

Each Interest Period specified in a Notice of Interest Rate Election shall
comply with the provisions of the definition of Interest Period.

          (c)  Upon receipt of a Notice of Interest Rate Election from the
Borrower pursuant to subsection (a) above, the Administrative Agent shall notify
each Bank on the same day as it receives such Notice of Interest Rate Election
of the contents thereof and such notice shall not thereafter be revocable by the
Borrower. If the Borrower fails to deliver a timely Notice of Interest Rate
Election to the Administrative Agent for any Group of Euro-Dollar Loans, such
Loans shall be converted into Base Rate Loans on the last day of the then
current Interest Period applicable thereto.

          Section II.16. Letters of Credit. (a) Subject to the terms contained
                         -----------------
in this Agreement and the other Loan Documents, upon the receipt of a notice in
accordance

                                       52



with Section 2.2(b) requesting the issuance of a Letter of Credit, the Fronting
Bank shall issue a Letter of Credit or Letters of Credit in such form as is
reasonably acceptable to the Borrower in an amount or amounts equal to the
amount or amounts requested by the Borrower.

          (b) Each Letter of Credit shall be issued in the minimum amount of One
Million Dollars ($1,000,000).

          (c) The Letter of Credit Usage shall be no more than Twenty-Five
Million Dollars ($25,000,000) at any one time.

          (d) There shall be no more than three (3) Letters of Credit
outstanding at any one time.

          (e) In the event of any request for a drawing under any Letter of
Credit by the beneficiary thereunder, the Fronting Bank shall endeavor to notify
the Borrower and the Administrative Agent (and the Administrative Agent shall
endeavor to notify each Bank thereof) on or before the date on which the
Fronting Bank intends to honor such drawing, and, except as provided in this
subsection (e), the Borrower shall reimburse the Fronting Bank, in immediately
available funds, on the same day on which such drawing is honored in an amount
equal to the amount of such drawing. Notwithstanding anything contained herein
to the contrary, however, unless the Borrower shall have notified the
Administrative Agent and the Fronting Bank prior to 2:00 p.m. (New York time) on
the Domestic Business Day immediately prior to the date of such drawing that the
Borrower intends to reimburse the Fronting Bank for the amount of such drawing
with funds other than the proceeds of the Loans, the Borrower shall be deemed to
have timely given a Notice of Committed Borrowing pursuant to Section 2.2 to the
Administrative Agent, requesting a Borrowing of Base Rate Loans on the date on
which such drawing is honored and in an amount equal to the amount of such
drawing. Each Bank (other than the Fronting Bank) shall, in accordance with
Section 2.4(b), make available its share of such Borrowing to the Administrative
Agent, the proceeds of which shall be applied directly by the Administrative
Agent to reimburse the Fronting Bank for the amount of such draw. In the event
that any such Bank fails to make available to the Fronting Bank the amount of
such Bank's participation on the date of a drawing, the Fronting Bank shall be
entitled to recover such amount on demand from such Bank together with interest
at the Federal Funds Rate commencing on the date such drawing is honored.

                                       53



          (f) If, at the time a beneficiary under any Letter of Credit requests
a drawing thereunder, an Event of Default as described in Section 6.1(f) or
Section 6.1(g) shall have occurred and is continuing, then on the date on which
the Fronting Bank shall have honored such drawing, the Borrower shall have an
unreimbursed obligation (the "Unreimbursed Obligation") to the Fronting Bank in
                              -----------------------
an amount equal to the amount of such drawing, which amount shall bear interest
at the annual rate of the sum of the Base Rate plus four percent (4%). Each Bank
shall purchase an undivided participating interest in the Unreimbursed
Obligation in an amount equal to its pro rata share of the Commitments, and upon
receipt thereof the Fronting Bank shall deliver to such Bank an Unreimbursed
Obligation participation certificate dated the date of the Fronting Bank's
receipt of such funds and in the amount of such Bank's pro rata share.

          (g) If, after the date hereof, any change in any law or regulation or
in the interpretation thereof by any court or administrative or governmental
authority charged with the administration thereof shall either (i) impose,
modify or deem applicable any reserve, special deposit or similar requirement
against letters of credit issued by, or assets held by, or deposits in or for
the account of, or participations in any letter of credit, upon any Bank
(including the Fronting Bank) or (ii) impose on any Bank any other condition
regarding this Agreement or such Bank (including the Fronting Bank) as it
pertains to the Letters of Credit or any participation therein and the result of
any event referred to in the preceding clause (i) or (ii) shall be to increase,
by an amount deemed by the Fronting Bank or such Bank to be material, the cost
to the Fronting Bank or any Bank of issuing or maintaining any Letter of Credit
or participating therein then the Borrower shall pay to the Fronting Bank or
such Bank, within 15 days after written demand by such Bank (with a copy to the
Administrative Agent), which demand shall be accompanied by a certificate
showing, in reasonable detail, the calculation of such amount or amounts, such
additional amounts as shall be required to compensate the Fronting Bank or such
Bank for such increased costs or reduction in amounts received or receivable
hereunder.

          (h) The Borrower hereby agrees to protect, indemnify, pay and save the
Fronting Bank harmless from and against any and all claims, demands,
liabilities, damages, losses, costs, charges and expenses (including reasonable
attorneys' fees and disbursements) which the Fronting Bank may incur or be
subject to as a result of (i) the issuance of the Letters of Credit, other than
as a result of the gross negligence or willful misconduct of the Fronting Bank
or (ii) the failure of the Fronting Bank to honor a drawing under any Letter of
Credit as a result of any act or omission, whether rightful or

                                       54



wrongful, of any present or future de jure or de facto government or

Governmental Authority (collectively, "Governmental Acts"), other than as a
                                       -----------------
result of the gross negligence or willful misconduct of the Fronting Bank. As
between the Borrower and the Fronting Bank, the Borrower assumes all risks of
the acts and omissions of, or misuses of, the Letters of Credit issued by the
Fronting Bank, by the beneficiaries of such Letters of Credit. In furtherance
and not in limitation of the foregoing, the Fronting Bank shall not be
responsible (i) for the form, validity, sufficiency, accuracy, genuineness or
legal effect of any document submitted by any party in connection with the
application for and issuance of such Letters of Credit, even if it should in
fact prove to be in any or all respects invalid, insufficient, inaccurate,
fraudulent or forged; (ii) for the validity or insufficiency of any instrument
transferring or assigning or purporting to transfer or assign any such Letter of
Credit or the rights or benefits thereunder or proceeds thereof, in whole or in
part, which may prove to be invalid or ineffective for any reason; (iii) for
failure of the beneficiary of any such Letter of Credit to comply fully with
conditions required in order to draw upon such Letter of Credit; (iv) for
errors, omissions, interruptions or delays in transmission or delivery of any
message, by mail, cable, telegraph, telex, facsimile transmission, or otherwise;
(v) for errors in interpretation of any technical terms; (vi) for any loss or
delay in the transmission or otherwise of any documents required in order to
make a drawing under any such Letter of Credit or of the proceeds thereof; (vii)
for the misapplication by the beneficiary of any such Letter of Credit of the
proceeds of such Letter of Credit; and (viii) for any consequence arising from
causes beyond the control of the Fronting Bank, including any Government Acts,
in each case other than as a result of the gross negligence or willful
misconduct of the Fronting Bank. None of the above shall affect, impair or
prevent the vesting of the Fronting Bank's rights and powers hereunder. In
furtherance and extension and not in limitation of the specific provisions
hereinabove set forth, any action taken or omitted by the Fronting Bank under or
in connection with the Letters of Credit issued by it or the related
certificates, if taken or omitted in good faith, shall not put the Fronting Bank
under any resulting liability to the Borrower.

          (i)  If the Fronting Bank or the Administrative Agent is required at
any time, pursuant to any bankruptcy, insolvency, liquidation or reorganization
law or otherwise, to return to the Borrower any reimbursement by the Borrower of
any drawing under any Letter of Credit, each Bank shall pay to the Fronting Bank
or the Administrative Agent, as the case may be, its share of such payment, but
without interest thereon unless the Fronting Bank or the Administrative Agent is
required to pay interest on such amounts to the person recovering such payment,
in which case with interest

                                       55

the Fronting Bank or the Administrative Agent is required to pay.

Credit against presentation of such draft or document shall not have constituted

payment in full of all obligations hereunder in respect of any Letter of Credit
or any agreement or instrument relating to any Letter of Credit, whether or not
similar to any of the foregoing, that might otherwise constitute a defense
available to, or a discharge of, the Borrower; provided, that such other

Environmental Claim against the Borrower or any Environmental Affiliate, or
(iii) the Borrower or the Environmental Affiliates shall have failed to obtain
any Environmental Approval necessary for the ownership, or operation of its
business, property or assets or any such Environmental Approval shall be
revoked, terminated, or otherwise cease to be in full force and effect, in the
case of clauses (i), (ii) or (iii) above, if the existence of such condition has
had or is reasonably likely to have a Material Adverse Effect;

              (m)   during any consecutive two year period commencing on or
after the date hereof, individuals who at the beginning of such period
constituted the Board of Directors of the General Partner of the Borrower
(together with any new directors whose election by the Board of Directors or
whose nomination for election by the General Partner stockholders was approved
by a vote of at least a majority of the members of the Board of Directors then
in the office who either were members of the Board of Directors at the beginning
of such period or whose election or nomination for election was previously so
approved) cease for any reason to constitute a majority of the members of the
Board of Directors then in office;

              (n)   the General Partner shall cease at any time to qualify as a
real estate investment trust under the Internal Revenue Code; and

              (o)   at any time, for any reason, the Borrower or the General
Partner seeks to repudiate its obligations under any Loan Document.

              Section VI.2. Rights and Remedies. (a) Upon the occurrence of any
                            -------------------
Event of Default described in Sections 6.1(f) or (g), the unpaid principal
amount of, and any and all accrued interest on, the Loans and any and all
accrued fees and other Obligations hereunder shall automatically become
immediately due and payable, with all additional interest from time to time
accrued thereon and without presentation, demand, or protest or other
requirements of any kind (including, without limitation, valuation and
appraisement, diligence, presentment, notice of intent to demand or accelerate
and notice of acceleration), all of which are hereby expressly waived by the
Borrower; and upon the occurrence and during the continuance of any other Event
of Default, the Administrative Agent may exercise any of its rights and remedies
hereunder and by written notice to the Borrower, declare the Commitment of each
Bank to make Loans to be terminated whereupon the same shall forthwith
terminate, declare the unpaid principal amount of and any and all accrued and
unpaid interest on the Loans and any and all accrued fees and other Obligations
hereunder to be, and the same shall thereupon be, immediately due and payable
with all additional interest from time to time accrued thereon and without
presentation, demand, or protest or other requirements of any kind other than as
provided in the Loan Documents (including, without limitation, valuation and
appraisement, diligence, presentment, and notice of intent to demand or
accelerate), all of which are hereby expressly waived by the Borrower.

              (b)   Notwithstanding the foregoing, upon the occurrence and
during the continuance of any Event of Default other than any Event of Default
described in Sections 6.1(f) or (g), the Administrative Agent shall not exercise
any of its rights and remedies hereunder nor declare the unpaid principal amount
of and any and all accrued and unpaid interest on the Loans and any and all
accrued fees and other Obligations hereunder to be immediately due and payable,
until such time as the Administrative Agent shall have delivered a notice to the
Banks specifying the Event of Default which has occurred and whether
Administrative Agent recommends the acceleration of the Obligations due
hereunder or the exercise of other remedies hereunder. The Banks shall notify
the Administrative Agent if they approve or disapprove of the acceleration of
the Obligations due hereunder or the exercise of such other remedy recommended
by Administrative Agent within five (5) Domestic Business Days after receipt of
such notice. If any Bank shall not respond within such five (5) Domestic
Business Day period, then such Bank shall be deemed to have accepted
Administrative Agent's recommendation for acceleration of the Obligations due
hereunder or the exercise of such other remedy. Regardless of the Administrative
Agent's recommendation, if the Required Banks shall approve the acceleration of
the Obligations due hereunder or the exercise of

                                       84



such other remedy, then Administrative Agent shall declare the Commitment of
each Bank to make Loans to be terminated whereupon the same shall forthwith
terminate and declare the unpaid principal amount of and any and all accrued and
unpaid interest on the Loans and any and all accrued fees and other Obligations
hereunder to be immediately due and payable or exercise such other remedy
approved by the Required Banks. If the Required Banks shall neither approve nor
disapprove the acceleration of the Obligations due hereunder or such other
remedy recommended by Administrative Agent, then Administrative Agent may
accelerate the Obligations due hereunder or exercise any of its rights and
remedies hereunder in its sole discretion. If the Required Banks shall
disapprove the acceleration of the Obligations due hereunder or the exercise of
such other remedy recommended by Administrative Agent, but approve of another
remedy, then to the extent permitted hereunder, Administrative Agent shall
exercise such remedy. In the event the Administrative Agent exercises any remedy
provided in any of the Loan Documents, the Administrative Agent shall act as a
collateral agent for the Banks.

                  (c) Notwithstanding the foregoing, if in Administrative
Agent's sole judgement, immediate action is required after an Event of Default
has occurred to prevent loss to the Banks, the Administrative Agent may exercise
any of its rights and remedies pursuant to this Agreement, including, without
limitation, acceleration of the Obligations hereunder, without the prior consent
of the Required Banks provided that the Administrative Agent has notified the
Banks of its intention so to exercise such rights and remedies and within 48
hours (such hours being counted only on Domestic Business Days) thereafter the
Required Banks have not instructed the Administrative Agent to the contrary.

                  Section VI.3. Notice of Default. If the Administrative Agent
                                -----------------
shall not already have given any notice to the Borrower under Section 6.1, the
Administrative Agent shall give notice to the Borrower under Section 6.1
promptly upon being requested to do so by the Required Banks and shall thereupon
notify all the Banks thereof.

                  Section VI.4. Actions in Respect of Letters of Credit. (a) If,
                                ---------------------------------------
at any time and from time to time, any Letter of Credit shall have been issued
hereunder and an Event of Default shall have occurred and be continuing, then,
upon the occurrence and during the continuation thereof, the Administrative
Agent may, and if requested by the Required Banks the Administrative Agent
shall, whether in addition to the taking by the Administrative Agent of any of
the actions described in this Article or otherwise, make a demand upon the
Borrower to, and forthwith upon such demand (but in any event within

                                       85



ten (10) days after such demand) the Borrower shall, pay to the Administrative
Agent, on behalf of the Banks, in same day funds at the Administrative Agent's
office designated in such demand, for deposit in a special cash collateral
account (the "Letter of Credit Collateral Account") to be maintained in the name
              -----------------------------------
of the Administrative Agent (on behalf of the Banks) and under its sole dominion
and control at such place as shall be designated by the Administrative Agent, an
amount equal to the amount of the Letter of Credit Usage under the Letters of
Credit. Interest shall accrue on the Letter of Credit Collateral Account at a
rate equal to the rate on overnight funds.

                  (b) The Borrower hereby pledges, assigns and grants to the
Administrative Agent, as administrative agent for its benefit and the ratable
benefit of the Banks a lien on and a security interest in, the following
collateral (the "Letter of Credit Collateral"):
                 ---------------------------

                      (i)   the Letter of Credit Collateral Account, all cash
         deposited therein and all certificates and instruments, if any, from
         time to time representing or evidencing the Letter of Credit Collateral
         Account;

                      (ii)  all notes, certificates of deposit and other
         instruments from time to time hereafter delivered to or otherwise
         possessed by the Administrative Agent for or on behalf of the Borrower
         in substitution for or in respect of any or all of the then existing
         Letter of Credit Collateral;

                      (iii) all interest, dividends, cash, instruments and other
         property from time to time received, receivable or otherwise
         distributed in respect of or in exchange for any or all of the then
         existing Letter of Credit Collateral; and

                      (iv)  to the extent not covered by the above clauses, all
         proceeds of any or all of the foregoing Letter of Credit Collateral.

The lien and security interest granted hereby secures the payment of all
obligations of the Borrower now or hereafter existing hereunder and under any
other Loan Document.

                  (c) The Borrower hereby authorizes the Administrative Agent
for the ratable benefit of the Banks to apply, from time to time after funds are
deposited in the Letter of Credit Collateral Account, funds then held in the
Letter of Credit Collateral Account to the payment of any amounts, in such order
as the Administrative Agent may

                                       86



elect, as shall have become due and payable by the Borrower to the Banks in
respect of the Letters of Credit.

                  (d)     Neither the Borrower nor any Person claiming or acting
on behalf of or through the Borrower shall have any right to withdraw any of the
funds held in the Letter of Credit Collateral Account, except as provided in
Section 6.4(h) hereof.

                  (e)     The Borrower agrees that it will not (i) sell or
otherwise dispose of any interest in the Letter of Credit Collateral or (ii)
create or permit to exist any lien, security interest or other charge or
encumbrance upon or with respect to any of the Letter of Credit Collateral,
except for the security interest created by this Section 6.4.

                  (f)     If any Event of Default shall have occurred and be
continuing:

                          (i) The Administrative Agent may, in its sole
         discretion, without notice to the Borrower except as required by law
         and at any time from time to time, charge, set off or otherwise apply
         all or any part of the Letter of Credit Collateral first, (x) amounts
                                                            -----
         previously drawn on any Letter of Credit that have not been reimbursed
         by the Borrower and (y) any Letter of Credit Usage described in clause
         (ii) of the definition thereof that are then due and payable and
         second, any other unpaid Obligations then due and payable against the
         ------
         Letter of Credit Collateral Account or any part thereof, in such order
         as the Administrative Agent shall elect. The rights of the
         Administrative Agent under this Section 6.4 are in addition to any
         rights and remedies which any Bank may have.

                          (ii) The Administrative Agent may also exercise, in
         its sole discretion, in respect of the Letter of Credit Collateral
         Account, in addition to the other rights and remedies provided herein
         or otherwise available to it, all the rights and remedies of a secured
         party upon default under the Uniform Commercial Code in effect in the
         State of New York at that time.

                  (g)     The Administrative Agent shall be deemed to have
exercised reasonable care in the custody and preservation of the Letter of
Credit Collateral if the Letter of Credit Collateral is accorded treatment
substantially equal to that which the Administrative Agent accords its own
property, it being understood that, assuming such treatment, the Administrative
Agent shall not have any responsibility or liability with respect thereto.

                                       87



                  (h)     At such time as all Events of Default have been cured
or waived in writing, all amounts remaining in the Letter of Credit Collateral
Account shall be promptly returned to the Borrower. Absent such cure or written
waiver, any surplus of the funds held in the Letter of Credit Collateral Account
and remaining after payment in full of all of the Obligations of the Borrower
hereunder and under any other Loan Document after the Maturity Date shall be
paid to the Borrower or to whomsoever may be lawfully entitled to receive such
surplus.

                                   ARTICLE VII

                            THE ADMINISTRATIVE AGENT

                  Section VII.1. Appointment and Authorization. Each Bank
                                 -----------------------------
irrevocably appoints and authorizes the Administrative Agent to take such action
as agent on its behalf and to exercise such powers under this Agreement and the
other Loan Documents as are delegated to the Administrative Agent by the terms
hereof or thereof, together with all such powers as are reasonably incidental
thereto. Except as otherwise expressly permitted by this Agreement or with the
prior written consent of the Administrative Agent, only the Administrative Agent
(and not one or more of the Banks) shall have the authority to deal directly
with the Borrower under this Agreement and each Bank acknowledges that all
notices, demands or requests from such Bank to Borrower must be forwarded to the
Administrative Agent for delivery to the Borrower. Each Bank acknowledges that,
except as otherwise expressly set forth in this Agreement, the Borrower has no
obligation to act or refrain from acting on instructions or demands of one or
more Banks absent written instructions from Administrative Agent in accordance
with its rights and authority hereunder.

                  Section VII.2. Administrative Agent and Affiliates. Chase
                                 -----------------------------------
shall have the same rights and powers under this Agreement as any other Bank and
may exercise or refrain from exercising the same as though it were not the
Administrative Agent, and Chase and its affiliates may accept deposits from,
lend money to, and generally engage in any kind of business with the Borrower or
any subsidiary or affiliate of the Borrower as if it were not the Administrative
Agent hereunder, and the term "Bank" and "Banks" shall include Chase in its
individual capacity.

                  Section VII.3. Action by Administrative Agent. (a) The
                                 ------------------------------
obligations of the Administrative Agent hereunder are only those expressly set
forth herein. Without

                                       88



limiting the generality of the foregoing, the Administrative Agent shall not be
required to take any action with respect to any Default, except as expressly
provided in Article VI. The Administrative Agent shall not have by reason of the
execution and delivery of the Loan Documents to which it is a party, the
performance of any of its obligations thereunder, or by the use of the term
"Administrative Agent", a fiduciary relationship in respect of any Bank or the
Borrower.

                  (b)   The Administrative Agent shall promptly forward, or make
available by Intralinks or other internet access system, to each Bank tangible
or electronic copies, or notify (in writing or electronically and, if
electronically, the Administrative Agent will also transmit a fax indicating
that the information in question is being transmitted electronically) each Bank
as to the contents, of all notices, financial statements and other significant
materials and communications received from the Borrower pursuant to the terms of
this Agreement or any other Loan Document and, in the event that the Borrower
fails to pay when due the principal of or interest on any Loan, the
Administrative Agent shall promptly give notice thereof to the Banks. As to any
matters not expressly provided for by the Loan Documents, the Administrative
Agent shall not be required to exercise any discretion or take any action, but
shall be required to act or to refrain from acting (and shall be fully protected
in so acting or refraining from acting) upon the instructions of the Required
Banks, and such instructions shall be binding upon all the Banks; provided,
however, that the Administrative Agent shall not be required to take any action
that exposes the Administrative Agent to personal liability or that is contrary
to this Agreement or applicable law. If the Borrower shall have made any payment
of principal of and interest on the Loans or any other amount due hereunder in
accordance with Article II hereof and the Administrative Agent shall not have
distributed to each Bank its proper share of such payment on the date on which
such payment shall be received (other than as a result of any shutdown of or
disturbance in any payment system or any other event or circumstance beyond the
reasonable control of the Administrative Agent), then the Administrative Agent
shall pay such proper share to such Bank together with interest thereon at the
Federal Funds Rate for each day from the date such payment shall have been
received from the Borrower until the date such amount is paid by the
Administrative Agent to such Bank. If any Bank transfers funds to the
Administrative Agent in anticipation of the making of a Loan that is
subsequently not made, then the Administrative Agent agrees to repay such funds
to such Bank upon the receipt of a notice from such Bank requesting the
repayment of such funds, together with interest thereon at the Federal Funds
Rate for each day from the date which is the day upon which Administrative Agent
shall have received a notice from

                                       89



such bank requesting the repayment of such funds until the date such amount is
paid by the Administrative Agent to such Bank.

                  Section VII.4. Consultation with Experts. The Administrative
                                 -------------------------
Agent may consult with legal counsel (who may be counsel for the Borrower),
independent public accountants and other experts selected by it and shall not be
liable for any action taken or omitted to be taken by it in good faith in
accordance with the advice of such counsel, accountants or experts.

                  Section VII.5. Liability of Administrative Agent. Neither the
                                 ---------------------------------
Administrative Agent nor any of its affiliates nor any of their respective
directors, officers, agents or employees shall be liable for any action taken or
not taken by it in connection herewith (i) with the consent or at the request of
the Required Banks or, where required by the terms of this Agreement, all of the
Banks, or (ii) in the absence of its own gross negligence or willful misconduct.
Neither the Administrative Agent nor any of its directors, officers, agents or
employees shall be responsible for or have any duty to ascertain, inquire into
or verify (i) any statement, warranty or representation made in connection with
this Agreement or any borrowing hereunder; (ii) the performance or observance of
any of the covenants or agreements of the Borrower; (iii) the satisfaction of
any condition specified in Article III, except receipt of items required to be
delivered to the Administrative Agent; or (iv) the validity, effectiveness or
genuineness of this Agreement, the other Loan Documents or any other instrument
or writing furnished in connection herewith. The Administrative Agent shall not
incur any liability by acting in reliance upon any notice, consent, certificate,
statement, or other writing (which may be a bank wire, telex or similar writing)
believed by it in good faith to be genuine or to be signed by the proper party
or parties.

                  Section VII.6. Indemnification. Each Bank shall, ratably in
                                 ---------------
accordance with its Commitment, indemnify the Administrative Agent, its
affiliates and their respective directors, officers, agents and employees (to
the extent not reimbursed by the Borrower) against any cost, expense (including
counsel fees and disbursements), claim, demand, action, loss or liability
(except such as result from such indemnitees' gross negligence or willful
misconduct) that such indemnitees may suffer or incur as a result of, or in
connection with, the Administrative Agent's capacity as Administrative Agent in
connection with this Agreement, the other Loan Documents or any action taken or
omitted by such indemnitees in accordance with this Agreement.

                                       90



                  Section VII.7. Credit Decision. Each Bank acknowledges that it
                                 ---------------
has, independently and without reliance upon the Administrative Agent or any
other Bank, and based on such documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into this
Agreement. Each Bank also acknowledges that it will, independently and without
reliance upon the Administrative Agent or any other Bank, and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit decisions in taking or not taking any action under this
Agreement.

                  Section VII.8. Successor Administrative Agent. The
                                 ------------------------------
Administrative Agent may resign at any time by giving notice thereof to the
Banks and the Borrower. In addition, if the Administrative Agent at any time
shall have been finally determined to have committed gross negligence or willful
misconduct in connection with its performance of its duties as Administrative
Agent hereunder or if the Commitment of the Administrative Agent, in its
capacity as a Bank, inclusive of participations, shall be less than $10,000,000,
then, upon notice from the Required Banks, the Administrative Agent shall
resign. Upon any such resignation, the Required Banks shall have the right to
appoint a successor Administrative Agent with the consent of the Borrower;
provided that the consent of the Borrower shall not be required if an Event of
Default shall have occurred and be continuing. If no successor Administrative
Agent shall have been so appointed by the Required Banks, and shall have
accepted such appointment, within 30 days after the retiring Administrative
Agent gives notice of resignation, then the retiring Administrative Agent may,
on behalf of the Banks, appoint a successor Administrative Agent, which shall be
a commercial bank organized or licensed under the laws of the United States of
America or of any State thereof and having a combined capital and surplus of at
least $500,000,000, total assets of at least $25,000,000,000 and a long-term
senior unsecured indebtedness rating of BBB+ or better by S&P (if rated by S&P)
and Baa1 by Moody's (if rated by Moody's). Upon the acceptance of its
appointment as the Administrative Agent hereunder by a successor Administrative
Agent, such successor Administrative Agent shall thereupon succeed to and become
vested with all the rights and duties of the retiring Administrative Agent, and
the retiring Administrative Agent shall be discharged from its duties and
obligations hereunder first accruing or arising after the effective date of such
retirement. After any retiring Administrative Agent's resignation hereunder as
Administrative Agent, the provisions of this Article shall inure to its benefit
as to any actions taken or omitted to be taken by it while it was the
Administrative Agent.

                                       91



                  If, at any time during the Term, the Administrative Agent
shall no longer have any Commitment under this Agreement, the Administrative
Agent shall give notice of its offer to resign to the Banks and the Borrower.
Upon any such offer of resignation, the Required Banks shall have the right to
appoint a successor Administrative Agent or to retain the Administrative Agent
with the consent of the Borrower; provided that the consent of the Borrower
shall not be required if an Event of Default shall have occurred and be
continuing.

                  Section VII.9.  Administrative Agent's Fee. The Borrower shall
                                  --------------------------
pay to the Administrative Agent for its own account fees in the amounts and at
the times previously agreed upon between the Borrower and the Administrative
Agent.

                  Section VII.10. Copies of Notices. Administrative Agent shall
                                  -----------------
deliver to each Bank a copy of any notice sent to the Borrower by Administrative
Agent in connection with the performance of its duties as Administrative Agent
hereunder; and Administrative Agent shall deliver to each Bank a copy of any
notice sent to the Administrative Agent by the Borrower in connection with any
Default or Event of Default hereunder.

                                  ARTICLE VIII

                             CHANGE IN CIRCUMSTANCES

                  Section VIII.1. Basis for Determining Interest Rate Inadequate
                                  ----------------------------------------------
or Unfair. If on or prior to the first day of any Interest Period for any
- ---------
Euro-Dollar Borrowing or Money Market Borrowing:

                  (a) the Administrative Agent is advised by the Reference Bank
that deposits in dollars (in the applicable amounts) are not being offered to
the Reference Bank in the relevant market for such Interest Period, or

                  (b) Banks having 50% or more of the aggregate amount of the
affected Loans advise the Administrative Agent that the Adjusted London
Interbank Offered Rate as determined by the Administrative Agent will not
adequately and fairly reflect the cost to such Banks of funding their
Euro-Dollar Loans for such Interest Period, the Administrative Agent shall
forthwith give notice thereof to the Borrower and the

                                       92



Banks, whereupon until the Administrative Agent notifies the Borrower that the
circumstances giving rise to such suspension no longer exist, the obligations of
the Banks to make Euro-Dollar Loans, or to continue or convert outstanding Loans
as or into Euro-Dollar Loans, as the case may be, shall be suspended, and each
outstanding Euro-Dollar Loan shall be converted into a Base Rate Loan on the
last day of the then current Interest Period applicable thereto. Unless the
Borrower notifies the Administrative Agent at least two Domestic Business Days
before the date of any Euro-Dollar Borrowing or Money Market LIBOR Borrowing for
which a Notice of Borrowing has previously been given that it elects not to
borrow on such date, (i) if such Borrowing is a Committed Borrowing, such
Borrowing shall instead be made as a Base Rate Borrowing, and (ii) if such
Borrowing is a Money Market LIBOR Borrowing, the Money Market LIBOR Loans
comprising such Borrowing shall bear interest for each day from and including
the first day to but excluding the last day of the Interest Period applicable
thereto at the Base Rate for such day.

                  Section VIII.2. Illegality. If, after the date of this
                                  ----------
Agreement, the adoption of any applicable law, rule or regulation, or any change
in any existing applicable law, rule or regulation, or any change 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 Bank (or its Euro-Dollar Lending Office) with any
request or directive (whether or not having the force of law) of any such
authority, central bank or comparable agency shall make it unlawful or
impossible for any Bank (or its Euro-Dollar Lending Office) to make, maintain or
fund its Euro-Dollar Loans or Money Market Loans or to participate in any Letter
of Credit issued by the Fronting Bank, or, with respect to the Fronting Bank, to
issue any Letter of Credit, and such Bank shall so notify the Administrative
Agent, the Administrative Agent shall forthwith give notice thereof to the other
Banks and the Borrower, whereupon until such Bank notifies the Borrower and the
Administrative Agent that the circumstances giving rise to such suspension no
longer exist, the obligation of such Bank to make or convert Euro-Dollar Loans
or Money Market Loans, or to participate in any Letter of Credit issued by the
Fronting Bank or, with respect to the Fronting Bank, to issue any Letter of
Credit, shall be suspended. Before giving any notice to the Administrative Agent
pursuant to this Section, such Bank shall designate a different Euro-Dollar
Lending Office if such designation will avoid the need for giving such notice
and will not, in the judgment of such Bank, be otherwise disadvantageous to such
Bank. If such Bank shall determine that it may not lawfully continue to maintain
and fund any of its outstanding Euro-Dollar Loans or Money Market Loans (as the
case may be) to maturity and shall so

                                       93



specify in such notice, the Borrower shall immediately prepay in full the then
outstanding principal amount of each such Euro-Dollar Loan or Money Market Loan,
together with accrued interest thereon. Concurrently with prepaying each such
Euro-Dollar Loan, the Borrower shall borrow a Base Rate Loan in an equal
principal amount from such Bank (on which interest and principal shall be
payable contemporaneously with the related Euro-Dollar Loans or Money Market
Loans of the other Banks), and such Bank shall make such a Base Rate Loan.

                  Section VIII.3. Increased Cost and Reduced Return.
                                  ---------------------------------

                  (a) If, after (x) the date hereof, in the case of any
Committed Loan or any obligation to make Committed Loans or (y) the date of the
related Money Market Quote, in the case of any Money Market Loan, the adoption
of any applicable law, rule or regulation, or any change in any applicable law,
rule or regulation, or any change 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 Bank (or
its Applicable Lending Office) with any request or directive (whether or not
having the force of law) of any such authority, central bank or comparable
agency shall impose, modify or deem applicable any reserve (including, without
limitation, any such requirement imposed by the Board of Governors of the
Federal Reserve System (but excluding with respect to any Euro-Dollar Loan any
such requirement reflected in an applicable Euro-Dollar Reserve Percentage)),
special deposit, insurance assessment or similar requirement against assets of,
deposits with or for the account of, or credit extended by, any Bank (or its
Applicable Lending Office) or shall impose on any Bank (or its Applicable
Lending Office) or on the London interbank market any other condition affecting
its Euro-Dollar Loans or Money Market LIBOR Loans, its Note, or its obligation
to make Euro-Dollar Loans, and the result of any of the foregoing is to increase
the cost to such Bank (or its Applicable Lending Office) of making or
maintaining any Euro-Dollar Loan, or to reduce the amount of any sum received or
receivable by such Bank (or its Applicable Lending Office) under this Agreement
or under its Note with respect thereto, by an amount deemed by such Bank to be
material, then, within 15 days after demand by such Bank (with a copy to the
Administrative Agent), which demand shall be accompanied by a certificate
showing, in reasonable detail, the calculation of such amount or amounts, the
Borrower shall pay to such Bank such additional amount or amounts as will
compensate such Bank for such increased cost or reduction.

                                       94



                  (b) If any Bank shall have determined that, after the date
hereof, the adoption of any applicable law, rule or regulation regarding capital
adequacy, or any change in any such law, rule or regulation, or any change in
the interpretation or administration thereof by any governmental authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or any request or directive regarding capital adequacy
(whether or not having the force of law) of any such authority, central bank or
comparable agency, has or would have the effect of reducing the rate of return
on capital of such Bank (or its Parent) as a consequence of such Bank's
obligations hereunder to a level below that which such Bank (or its Parent)
could have achieved but for such adoption, change, request or directive (taking
into consideration its policies with respect to capital adequacy) by an amount
deemed by such Bank to be material, then from time to time, within 15 days after
demand by such Bank (with a copy to the Administrative Agent), which demand
shall be accompanied by a certificate showing, in reasonable detail, the
calculation of such amount or amounts, the Borrower shall pay to such Bank such
additional amount or amounts as will compensate such Bank (or its Parent) for
such reduction.

                  (c) Each Bank will promptly notify the Borrower and the
Administrative Agent of any event of which it has knowledge, occurring after the
date hereof, which will entitle such Bank to compensation pursuant to this
Section (although failure or delay on the part of any Bank to provide such
notice or to demand compensation pursuant to this Section, after receiving
notice of increased cost or reduced rate of return, shall not constitute a
waiver of such Bank's right to demand such compensation unless such failure
materially prejudices Borrower's rights hereunder) and will designate a
different Applicable Lending Office if such designation will avoid the need for,
or reduce the amount of, such compensation and will not, in the judgment of such
Bank, be otherwise disadvantageous to such Bank. A certificate of any Bank
claiming compensation under this Section and setting forth the additional amount
or amounts to be paid to it hereunder shall be conclusive in the absence of
manifest error. In determining such amount, such Bank may use any reasonable
averaging and attribution methods.

                  Section VIII.4.  Taxes.
                                   -----

                  (a) Any and all payments by the Borrower to or for the account
of any Bank or the Administrative Agent hereunder or under any other Loan
Document shall be made free and clear of and without deduction for any and all
present or future taxes, duties, levies, imposts, deductions, charges or
withholdings, and all liabilities, including,

                                       95



without limitation, penalties, interest and expenses, with respect thereto,
excluding, in the case of each Bank and the Administrative Agent, taxes imposed
- ---------
on its income, and franchise taxes imposed on it, by the jurisdiction under the
laws of which such Bank or the Administrative Agent (as the case may be) is
organized or any political subdivision thereof and, in the case of each Bank,
taxes imposed on its income, and franchise or similar taxes imposed on it, by
the jurisdiction of such Bank's Applicable Lending Office or any political
subdivision thereof (and, if different from the jurisdiction of such Bank's
Applicable Lending Office, the jurisdiction of the domicile of its Loans either
established by the Bank pursuant to Section 9.12 or determined by the applicable
taxing authorities)(all such non-excluded taxes, duties, levies, imposts,
deductions, charges, withholdings and liabilities being hereinafter referred to
as "Taxes"). If the Borrower shall be required by law to deduct any Taxes from
    -----
or in respect of any sum payable hereunder or under any Note or Letter of Credit
or participation therein to any Bank or the Administrative Agent, (i) the sum
payable shall be increased as necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section 8.4) such Bank, the Fronting Bank or the Administrative Agent (as
the case may be) receives an amount equal to the sum it would have received had
no such deductions been made, (ii) the Borrower shall make such deductions,
(iii) the Borrower shall pay the full amount deducted to the relevant taxation
authority or other authority in accordance with applicable law and (iv) the
Borrower shall furnish to the Administrative Agent, at its address referred to
in Section 9.1, the original or a certified copy of a receipt evidencing payment
thereof.

                  (b) In addition, the Borrower agrees to pay any present or
future stamp or documentary taxes and any other excise or property taxes, or
charges or similar levies which arise from any payment made hereunder or under
any Note or Letter of Credit or participation therein or from the execution or
delivery of, or otherwise with respect to, this Agreement or any Note or Letter
of Credit or participation therein (hereinafter referred to as "Other Taxes").
                                                                -----------

                  (c) The Borrower agrees to indemnify each Bank, the Fronting
Bank and the Administrative Agent for the full amount of Taxes or Other Taxes
(including, without limitation, any Taxes or Other Taxes imposed or asserted by
any jurisdiction on amounts payable under this Section 8.4) paid by such Bank,
the Fronting Bank or the Administrative Agent (as the case may be) and any
liability (including penalties, interest and expenses) arising therefrom or with
respect thereto (whether or not such Taxes or Other Taxes were correctly or
legally imposed or asserted by the relevant Governmental Authority). Any payment
required under this indemnification shall be made within 15

                                       96



days from the date such Bank, the Fronting Bank or the Administrative Agent (as
the case may be) makes demand therefor. The Administrative Agent shall
reasonably cooperate, at no cost to the Administrative Agent or the Banks, with
efforts by Borrower to recover any Taxes or Other Taxes which Borrower
reasonably believes were incorrectly or illegally imposed.

                  (d) Each Bank organized under the laws of a jurisdiction
outside the United States, on or prior to the date of its execution and delivery
of this Agreement in the case of each Bank listed on the signature pages hereof
and on or prior to the date on which it becomes a Bank in the case of each other
Bank, and from time to time thereafter if requested in writing by the Borrower
(but only so long as such Bank remains lawfully able to do so), shall provide
the Borrower with Internal Revenue Service form 1001 or 4224, as appropriate, or
any successor form prescribed by the Internal Revenue Service, certifying that
such Bank is entitled to benefits under an income tax treaty to which the United
States is a party which reduces the rate of withholding tax on payments of
interest or certifying that the income receivable pursuant to this Agreement is
effectively connected with the conduct of a trade or business in the United
States. If the form provided by a Bank at the time such Bank first became a
party to this Agreement or at any time thereafter (other than solely by reason
of a change in United States law or a change in the terms of any treaty to which
the United States is a party after the date hereof) indicates a United States
interest withholding tax rate in excess of zero (or would have indicated such a
withholding tax rate if such form had been submitted and completed accurately
and completely and either was not submitted or was not completed accurately and
completely), or if a Bank otherwise is subject to United States interest
withholding tax at a rate in excess of zero at any time for any reason (other
than solely by reason of a change in United States law or regulation or a change
in any treaty to which the United States is a party after the date hereof),
withholding tax at such rate shall be considered excluded from "Taxes" as
defined in Section 8.4(a). In addition, any amount that otherwise would be
considered "Taxes" or "Other Taxes" for purposes of this Section 8.4 shall be
excluded therefrom if the Bank either has transferred the domicile of its Loans
pursuant to Section 9.12 or changed the Applicable Lending Office with respect
to such Loans and such amount would not have been incurred had such transfer or
change not been made.

                  (e) For any period with respect to which a Bank has failed to
provide the Borrower with the appropriate form pursuant to Section 8.4(d)
(unless such failure is due to a change in treaty, law or regulation occurring
subsequent to the date on which a

                                       97



form originally was required to be provided), such Bank shall not be entitled to
indemnification under Section 8.4(a) with respect to Taxes imposed by the United
States; provided, however, that should a Bank, which is otherwise exempt from or
        --------  -------
subject to a reduced rate of withholding tax, become subject to Taxes because of
its failure to deliver a form required hereunder, the Borrower shall take such
steps as such Bank shall reasonably request to assist such Bank to recover such
Taxes.

                  (f) If the Borrower is required to pay additional amounts to
or for the account of any Bank pursuant to this Section 8.4, then such Bank will
change the jurisdiction of its Applicable Lending Office so as to eliminate or
reduce any such additional payment which may thereafter accrue if such change,
in the judgment of such Bank, is not otherwise disadvantageous to such Bank.

                  Section VIII.5. Base Rate Loans Substituted for Affected
                                  ----------------------------------------
Euro-Dollar Loans. If (i) the obligation of any Bank to make, or convert
- -----------------
outstanding Loans to, Euro-Dollar Loans has been suspended pursuant to Sections
8.1 or 8.2 or (ii) any Bank has demanded compensation under Section 8.3 or 8.4
with respect to its Euro-Dollar Loans and the Borrower shall, by at least five
(5) Euro-Dollar Business Days' prior notice to such Bank through the
Administrative Agent, have elected that the provisions of this Section shall
apply to such Bank, then, unless and until such Bank notifies the Borrower that
the circumstances giving rise to such suspension or demand for compensation no
longer exist:

                  (a) all Loans which would otherwise be made by such Bank as
Euro-Dollar Loans shall be made instead as Base Rate Loans (on which interest
and principal shall be payable contemporaneously with the related Euro-Dollar
Loans of the other Banks), and

                  (b) after each of its Euro-Dollar Loans has been repaid, all
payments of principal which would otherwise be applied to repay such Euro-Dollar
Loans shall be applied to repay its Base Rate Loans instead.

                  Section VIII.6. SPC Loans. Notwithstanding anything to the
                                  ---------
contrary contained herein, any Bank (a "Granting Bank") may grant to one special
                                        -------------
purpose funding vehicle (an "SPC") sponsored by such Granting Bank, as
                             ---
identified as such in writing by such Granting Bank to the Administrative Agent
and the Borrower from

                                       98



time to time (including, without limitation, by the execution of this Agreement
on the date hereof by a Granting Bank and its SPC identified as such on the
signature pages hereof), the option to provide to the Borrower all or any part
of any Loan that such Granting Bank would otherwise be obligated to make to the
Borrower pursuant to the terms hereof; provided, that (i) nothing herein shall
                                       --------
constitute a commitment to make any Loan by any SPC, and (ii) if an SPC elects
not to exercise such option or otherwise fails to provide all or any part of
such Loan, the Granting Bank shall be obligated to make such Loan pursuant to
the terms hereof. The making of a Loan by an SPC hereunder shall utilize the
Commitment of such Granting Bank to the same extent, and as if, such Loan were
made by such Granting Bank. Any SPC that makes a Loan shall (i) have in regard
to such Loan all of the rights (exercisable, however, only through its Granting
Bank acting as its agent) that such Granting Bank would have had if it had made
such Loan directly, and (ii) comply with this Agreement in regard to such Loan
on the same terms as any other Bank party hereto; provided that (A) the Granting
Bank's Commitment shall remain the Commitment of such Granting Bank, and (B) all
monetary obligations of an SPC hereunder in respect of any Loan it provides
shall remain the obligations of such Granting Bank to the extent at any time
that such SPC elects not to or otherwise fails to perform or pay any such
obligation. Each party hereto hereby agrees that no SPC shall be liable for any
payment under this Agreement for which a Bank would otherwise be liable for so
long as, and to the extent, its sponsoring Granting Bank makes such payment.
Notwithstanding any Loan that may be provided by an SPC hereunder, the
Administrative Agent and Borrower shall be entitled to continue to communicate
and deal solely and directly with the Granting Bank in accordance with this
Agreement in respect of such Loan. Each SPC that is a signatory hereto, and each
SPC that subsequently is identified by its Granting Bank as having been granted
such option, shall be deemed to have confirmed (and the Borrower and the
Administrative Agent may require a written acknowledgment of such confirmation
signed by any SPC not a signatory hereto that is subsequently so identified by
its Granting Bank) to the Borrower and the Administrative Agent that (a) it has
received a copy of the Agreement and each Loan Document, together with copies of
the financial statements heretofore provided to the Banks under the terms of
this Agreement and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into this
Agreement; (b) agrees that it will independently and without reliance upon the
Administrative Agent, its Granting Bank or any other Bank, and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit decisions in taking or not taking action under the Agreement
and any other Loan Document; (c) appoints and authorizes the Administrative
Agent to take such action as agent on its behalf and to exercise such powers and
discretion under this Agreement and any other Loan

                                       99



Document as are delegated to the Administrative Agent by the terms thereof,
together with such powers and discretion as are reasonably incidental thereto;
(d) agrees that it will perform in accordance with their terms all of the
obligations which by the terms of this Agreement and any other Loan Document are
required to be performed by it as a Bank, subject to the terms of this Section
                                                                       -------
8.6; and (e) appoints its Granting Bank, or a specified branch or affiliate
- ---
thereof, as its agent and attorney in fact and grants to its Granting Bank an
irrevocable power of attorney to receive payments made for the benefit such SPC
under this Agreement, to deliver and receive all communications and notices
under this Agreement and other Loan Documents and to exercise on such SPC's
behalf all rights to vote and to grant and make approvals, waivers, consents of
amendments to or under this Agreement and other Loan Documents. Any document
executed by such agent on such SPC's behalf in connection with this Agreement or
other Loan Documents shall be binding on such SPC. In furtherance of the
foregoing, all the Banks and the Administrative Agent each hereby agrees (which
agreement shall survive the termination of this Agreement) that, prior to the
date that is one (1) year and one (1) day after the payment in full of all
outstanding commercial paper or other senior indebtedness of any SPC, it will
not institute against, or join any other person in instituting against, such SPC
any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceedings or similar proceedings under the laws of the United States or any
State thereof. In addition, notwithstanding anything to the contrary contained
in Section 9.6(c), any SPC may (i) with notice to, but without the prior written
consent of, the Borrower or Administrative Agent, and without the payment of any
processing fee therefor, assign all or a portion of its interests in any Loans
to its Granting Bank or to any financial institutions consented to by the
Borrower and the Administrative Agent (and, subject to all of the provisions of
this paragraph, such consents shall be deemed to have been granted with respect
to any SPC signatory hereto on the date hereof) providing liquidity and/or
credit facilities to or for the account of such SPC to support the funding or
maintenance of loans, and (ii) disclose on a confidential basis any non-public
information relating to its Loans to any rating agency, commercial paper dealer
or provider of liquidity and/or credit facilities to such SPC. Nothing in this
Section 8.6 that would affect the rights or obligations of an SPC may be amended
without the written consent of any SPC that has any Loan outstanding at the time
of such amendment.

                                -------------------------

                  (a) The Borrower shall pay (i) all reasonable out-of-pocket
expenses of the Administrative Agent (including, without limitation, reasonable
fees and disbursements of special counsel Skadden, Arps, Slate, Meagher & Flom
LLP, local counsel for the Administrative Agent, and travel, site visits, third

Default and collection, bankruptcy, insolvency and other enforcement proceedings
resulting therefrom.

                  (b) The Borrower agrees to indemnify the Administrative Agent
and each Bank, their respective affiliates and the respective directors,
officers, agents and employees of the foregoing (each an "Indemnitee") and hold

reasonable fees and disbursements of counsel and settlements and settlement
costs, which may be incurred by such Indemnitee in connection with any
investigative, administrative or judicial proceeding (whether or not such
Indemnitee shall be designated a party thereto) that may at any time (including,
without limitation, at any time following the payment of the Obligations) be
imposed on, asserted against or incurred by any Indemnitee as a result of, or
arising out of, or in any way related to or by reason of, (i) any of the
transactions contemplated by the Loan Documents or the execution, delivery or
performance of any Loan Document (including, without limitation, the Borrower's
actual or proposed use of proceeds of the Loans, whether or not in compliance
with the provisions hereof), (ii) any violation by the Borrower or the
Environmental Affiliates of any applicable Environmental Law, (iii) any
Environmental Claim arising out of the management, use, control, ownership or

involving Material of Environmental Concern, (iv) the breach of any
environmental representation or warranty set forth herein, (v) the grant to the

Borrower or any stock or other equity interest in the Borrower, and (vi) the
exercise by the Administrative Agent and the Banks of their rights and remedies
(including, without limitation, foreclosure) under any agreements creating any
such Lien (but excluding in each case, as to any Indemnitee, any such losses,
liabilities, claims, damages, expenses, obligations, penalties, actions,
judgments, suits, costs or disbursements incurred solely by reason of (y) the
gross negligence or willful misconduct of such Indemnitee as finally determined
by a court of competent jurisdiction or (z) any

investigative, administrative or judicial proceeding imposed or asserted against
any Indemnitee by any bank regulatory agency or by any equity holder of such
Indemnitee). The Borrower's obligations under this Section shall survive the
termination of this Agreement and the payment of the Obligations.

                  (c) The Borrower shall pay, and hold the Administrative Agent
and each of the Banks harmless from and against, any and all present and future
U.S. stamp, recording, transfer and other similar foreclosure related taxes with
respect to the foregoing matters and hold the Administrative Agent and each Bank
harmless from and against any and all liabilities with respect to or resulting
from any delay or omission (other than to the extent attributable to such Bank)
to pay such taxes.

                  Section IX.4. Sharing of Set-Offs. In addition to any rights
                                -------------------
now or hereafter granted under applicable law or otherwise, and not by way of
limitation of any such rights, upon the occurrence and during the continuance of
any Event of Default, each Bank is hereby authorized at any time or from time to
time, without presentment, demand, protest or other notice of any kind to the
Borrower or to any other Person, any such notice being hereby expressly waived,
to set off and to appropriate and apply any and all deposits (general or
special, time or demand, provisional or final), other than deposits held for the
benefit of third parties, and any other indebtedness at any time held or owing
by such Bank (including, without limitation, by branches and agencies of such
Bank wherever located) to or for the credit or the account of the Borrower
against and on account of the Obligations of the Borrower then due and payable
to such Bank under this Agreement or under any of the other Loan Documents,
including, without limitation, all interests in Obligations purchased by such
Bank. Each Bank agrees that if it shall, by exercising any right of set-off or
counterclaim or otherwise, receive payment of a proportion of the aggregate
amount of principal and interest due with respect to any Note held by it or
Letter of Credit participated in by it, or, in the case of the Fronting Bank,
Letter of Credit issued by it, which is greater than the proportion received by
any other Bank or Letter of Credit issued or participated in by such other Bank,
in respect of the aggregate amount of principal and interest due with respect to
any Note held by such other Bank, the Bank receiving such proportionately
greater payment shall purchase such participations in the Notes held by the
other Banks or Letter of Credit issued or participated in by such other Bank,
and such other adjustments shall be made, as may be required so that all such
payments of principal and interest with respect to the Notes held by the Banks
or Letter of Credit issued or participated in by such other Banks shall be
shared by the Banks pro rata; provided that nothing in this Section shall impair

                                      103



of any Bank to exercise any right of set-off or counterclaim it may have and to
apply the amount subject to such exercise to the payment of indebtedness of the
Borrower other than its indebtedness under the Notes or the Letters of Credit.
The Borrower agrees, to the fullest extent that it may effectively do so under
applicable law, that any holder of a participation in a Note, whether or not
acquired pursuant to the foregoing arrangements, may exercise rights of set-off
or counterclaim and other rights with respect to such participation as fully as
if such holder of a participation were a direct creditor of the Borrower in the
amount of such participation.

                  Section IX.5. Amendments and Waivers. Any provision of this
                                ----------------------
Agreement (including any of the financial covenants given by the Borrower
pursuant to Section 5.8), the Notes, the Letters of Credit or other Loan
Documents may be amended or waived if, but only if, such amendment or waiver is
in writing and is signed by the Borrower and the Required Banks (and, if the
rights or duties of the Administrative Agent are affected thereby, by the
Administrative Agent); provided that no such amendment or waiver shall, unless
                       --------
signed by all the Banks, (i) increase or decrease the Commitment of any Bank
(except for a ratable decrease in the Commitments of all Banks and except as
contemplated in the definition of the term "Loan Amount"), increase the
aggregate Commitments above $500,000,000, or subject any Bank to any additional
obligation, (ii) reduce the principal of or rate of interest on any Loan or any
fees specified herein, (iii) postpone the date fixed for any payment of
principal of or interest on any Loan or any fees hereunder or for any reduction
or termination of any Commitment, (iv) release the Guaranty or otherwise release
any other collateral, (v) subordinate the Loans to any other Debt, or (vi)
change the percentage of the Commitments or of the aggregate unpaid principal
amount of the Notes, or the number of Banks, which shall be required for the
Banks or any of them to take any action under this Section 9.5 or any other
provision of this Agreement. Notwithstanding the foregoing, no amendment, waiver
or consent shall, unless in writing and signed by the Designating Lender on
behalf of its Designated Lender affected thereby, (a) subject such Designated
Lender to any additional obligations, (b) reduce the principal of, interest on,
or other amounts due with respect to, the Designated Lender Note made payable to
such Designated Lender, or (c) postpone any date fixed for any payment of
principal of, or interest on, or other amounts due with respect to the
Designated Lender Note made payable to the Designated Lender.

                  Section IX.6. Successors and Assigns.
                                ----------------------

                                      104



              (a)   The provisions of this Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
assigns, except that the Borrower may not assign or otherwise transfer any of
its rights under this Agreement or the other Loan Documents without the prior
written consent of all Banks.

              (b)   Any Bank may at any time grant to one or more banks or other
entities (each a "Participant") participating interests in its Commitment or any
                  -----------
or all of its Loans. In the event of any such grant by a Bank of a participating
interest to a Participant, whether or not upon notice to the Borrower and the
Administrative Agent, such Bank shall remain responsible for the performance of
its obligations hereunder, and the Borrower and the Administrative Agent shall
continue to deal solely and directly with such Bank in connection with such
Bank's rights and obligations under this Agreement. Any agreement pursuant to
which any Bank may grant such a participating interest shall provide that such
Bank shall retain the sole right and responsibility to enforce the obligations
of the Borrower hereunder including, without limitation, the right to approve
any amendment, modification or waiver of any provision of this Agreement;
provided that such participation agreement may provide that such Bank will not
- --------
agree to any modification, amendment or waiver of this Agreement described in
clause (i), (ii), (iii) or (iv) of Section 9.5 without the consent of the
Participant. The Borrower agrees that each Participant shall, to the extent
provided in its participation agreement, be entitled to the benefits of Article
VIII with respect to its participating interest. An assignment or other transfer
which is not permitted by subsection (c) or (d) below shall be given effect for
purposes of this Agreement only to the extent of a participating interest
granted in accordance with this subsection (b).

              (c)   Any Bank may at any time assign to one or more banks or
other institutions (each an "Assignee") all, or a proportionate part of all, of
                             --------
its rights and obligations under this Agreement, the Notes and the other Loan
Documents, and such Assignee shall assume such rights and obligations, pursuant
to an Assignment and Assumption Agreement in substantially the form of Exhibit D
                                                                       ---------
attached hereto executed by such Assignee and such transferor Bank, with (and
subject to) the subscribed consent of the Administrative Agent, which consent
shall not be unreasonably withheld, and, provided no Event of Default shall have
occurred and be continuing, the Borrower, which consent shall not be
unreasonably withheld or delayed. Upon execution and delivery of such instrument
and payment by such Assignee to such transferor Bank of an amount equal to the
purchase price agreed between such transferor Bank and such Assignee, such
Assignee shall be a Bank party to this Agreement and shall have all the rights
and

                                      105



obligations of a Bank with a Commitment as set forth in such instrument of
assumption, and the transferor Bank shall be released from its obligations
hereunder to a corresponding extent, and no further consent or action by any
party shall be required. Upon the consummation of any assignment pursuant to
this subsection (c), the transferor Bank, the Administrative Agent and the
Borrower shall make appropriate arrangements so that, if required, a new Note or
Notes are issued to the Assignee. In connection with any such assignment (except
for an assignment by a Bank to its Affiliate), the transferor Bank shall pay to
the Administrative Agent an administrative fee for processing such assignment in
the amount of $3,500. If the Assignee is not incorporated under the laws of the
United States of America or a state thereof, it shall deliver to the Borrower
and the Administrative Agent certification as to exemption from deduction or
withholding of any United States federal income taxes in accordance with Section
8.4.

              (d)   Any Bank (each, a "Designating Lender") may at any time
                                       ------------------
designate one Designated Lender to fund Money Market Loans on behalf of such
Designating Lender subject to the terms of this Section 9.6(d) and the
provisions in Section 9.6(b) and (c) shall not apply to such designation. No
Bank may designate more than one (1) Designated Lender. The parties to each such
designation shall execute and deliver to the Administrative Agent for its
acceptance a Designation Agreement. Upon such receipt of an appropriately
completed Designation Agreement executed by a Designating Lender and a designee
representing that it is a Designated Lender, the Administrative Agent will
accept such Designation Agreement and will give prompt notice thereof to the
Borrower, whereupon, (i) the Borrower shall execute and deliver to the
Designating Bank a Designated Lender Note payable to the order of the Designated
Lender, (ii) from and after the effective date specified in the Designation
Agreement, the Designated Lender shall become a party to this Agreement with a
right (subject to the provisions of Section 2.3(b)) to make Money Market Loans
on behalf of its Designating Lender pursuant to Section 2.3 after the Borrower
has accepted a Money Market Loan (or portion thereof) of the Designating Lender,
and (iii) the Designated Lender shall not be required to make payments with
respect to any obligations in this Agreement except to the extent of excess cash
flow of such Designated Lender which is not otherwise required to repay
obligations of such Designated Lender which are then due and payable; provided,
however, that regardless of such designation and assumption by the Designated
Lender, the Designating Lender shall be and remain obligated to the Borrower and
the Banks for each and every of the obligations of the Designating Lender and
its related Designated Lender with respect to this Agreement, including, without
limitation, any indemnification obligations under Section 7.6 hereof and any
sums otherwise payable to

                                      106



the Borrower by the Designated Lender. Each Designating Lender shall serve as
the administrative agent of the Designated Lender and shall on behalf of, and to
the exclusion of, the Designated Lender: (i) receive any and all payments made
for the benefit of the Designated Lender and (ii) give and receive all
communications and notices and take all actions hereunder, including, without
limitation, votes, approvals, waivers, consents and amendments under or relating
to this Agreement and the other Loan Documents. Any such notice, communication,
vote, approval, waiver, consent or amendment shall be signed by the Designating
Lender as administrative agent for the Designated Lender and shall not be signed
by the Designated Lender on its own behalf and shall be binding upon the
Designated Lender to the same extent as if signed by the Designated Lender on
its own behalf. The Borrower, the Administrative Agent, and the Banks may rely
thereon without any requirement that the Designated Lender sign or acknowledge
the same. No Designated Lender may assign or transfer all or any portion of its
interest hereunder or under any other Loan Document, other than assignments to
the Designating Lender which originally designated such Designated Lender or
otherwise in accordance with the provisions of Section 9.6(b) and (c).

              (e)   Any Bank may at any time assign all or any portion of its
rights under this Agreement and its Note and the Letter(s) of Credit
participated in by such Bank or, in the case of the Fronting Bank, issued by it,
to a Federal Reserve Bank. No such assignment shall release the transferor Bank
from its obligations hereunder.

              (f)   No Assignee, Participant or other transferee of any Bank's
rights shall be entitled to receive any greater payment under Section 8.3 or 8.4
than such Bank would have been entitled to receive with respect to the rights
transferred, unless such transfer is made with the Borrower's prior written
consent or by reason of the provisions of Section 8.2, 8.3 or 8.4 requiring such
Bank to designate a different Applicable Lending Office under certain
circumstances or at a time when the circumstances giving rise to such greater
payment did not exist.

              Section IX.7. Governing Law; Submission to Jurisdiction.
                            -----------------------------------------

              (a)   THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS AND THE RIGHTS
AND OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE CONSTRUED IN
ACCORDANCE WITH AND BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK (WITHOUT
GIVING EFFECT TO THE PRINCIPLES THEREOF RELATING TO CONFLICTS OF LAW).

                                      107



              (b)   Any legal action or proceeding with respect to this
Agreement or any other Loan Document and any action for enforcement of any
judgment in respect thereof may be brought in the courts of the State of New
York or of the United States of America for the Southern District of New York,
and, by execution and delivery of this Agreement, the Borrower hereby accepts
for itself and in respect of its property, generally and unconditionally, the
non-exclusive jurisdiction of the aforesaid courts and appellate courts from any
thereof. The Borrower irrevocably consents to the service of process out of any
of the aforementioned courts in any such action or proceeding by the hand
delivery, or mailing of copies thereof by registered or certified mail, postage
prepaid, to the Borrower at its address set forth below. The Borrower hereby
irrevocably waives any objection which it may now or hereafter have to the
laying of venue of any of the aforesaid actions or proceedings arising out of or
in connection with this Agreement or any other Loan Document brought in the
courts referred to above and hereby further irrevocably waives and agrees not to
plead or claim in any such court that any such action or proceeding brought in
any such court has been brought in an inconvenient forum. Nothing herein shall
affect the right of the Administrative Agent, any Bank or any holder of a Note
to serve process in any other manner permitted by law or to commence legal
proceedings or otherwise proceed against the Borrower in any other jurisdiction.

              Section IX.8. Marshaling; Recapture. Neither the Administrative
                            ---------------------
Agent nor any Bank shall be under any obligation to marshal any assets in favor
of the Borrower or any other party or against or in payment of any or all of the
Obligations. To the extent any Bank receives any payment by or on behalf of the
Borrower, which payment or any part thereof is subsequently invalidated,
declared to be fraudulent or preferential, set aside or required to be repaid to
the Borrower or its estate, trustee, receiver, custodian or any other party
under any bankruptcy law, state or federal law, common law or equitable cause,
then to the extent of such payment or repayment, the Obligation or part thereof
which has been paid, reduced or satisfied by the amount so repaid shall be
reinstated by the amount so repaid and shall be included within the liabilities
of the Borrower to such Bank as of the date such initial payment, reduction or
satisfaction occurred.

              Section IX.9. Counterparts; Integration; Effectiveness. This
                            ----------------------------------------
Agreement may be signed in any number of counterparts, each of which shall be an
original, with the same effect as if the signatures thereto and hereto were upon
the same instrument. This

                                      108



Agreement constitutes the entire agreement and understanding among the parties
hereto and supersedes any and all prior agreements and understandings, oral or
written, relating to the subject matter hereof. This Agreement shall become
effective upon receipt by the Administrative Agent of counterparts hereof signed
by each of the parties hereto (or, in the case of any party as to which an
executed counterpart shall not have been received, receipt by the Administrative
Agent in form satisfactory to it of telegraphic, telex or other written
confirmation from such party of execution of a counterpart hereof by such
party).

              Section IX.10. WAIVER OF JURY TRIAL. EACH OF THE BORROWER, THE
                             --------------------
Administrative Agent AND THE BANKS HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT
TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS
AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

              Section IX.11. Survival. All indemnities set forth herein shall
                             --------
survive the execution and delivery of this Agreement and the other Loan
Documents and the making and repayment of the Loans hereunder.

              Section IX.12. Domicile of Loans. Subject to the provisions of
                             -----------------
Article VIII, each Bank may transfer and carry its Loans at, to or for the
account of any domestic or foreign branch office, subsidiary or affiliate of
such Bank.

              Section IX.13. Limitation of Liability. No claim may be made by
                             -----------------------
the Borrower or any other Person against the Administrative Agent or any Bank or
the affiliates, directors, officers, employees, attorneys or agent of any of
them for any consequential or punitive damages in respect of any claim for
breach of contract or any other theory of liability arising out of or related to
the transactions contemplated by this Agreement or by the other Loan Documents,
or any act, omission or event occurring in connection therewith; and the
Borrower hereby waives, releases and agrees not to sue upon any claim for any
such damages, whether or not accrued and whether or not known or suspected to
exist in its favor.

              Section IX.14. No Bankruptcy Proceedings. Each of the Borrower,
                             -------------------------
the Banks, and the Administrative Agent hereby agrees that it will not institute
against any Designated Lender or join any other Person in instituting against
any Designated Lender any bankruptcy, reorganization, arrangement, insolvency or
liquidation proceeding under any federal or state bankruptcy or similar law,
until the later to occur of (i) one year and

                                      109



one day after the payment in full of the latest maturing commercial paper note
issued by such Designated Lender and (ii) the Maturity Date.

                                      110



              IN WITNESS WHEREOF, the parties hereto have caused this Agreement
to be duly executed by their respective authorized officers as of the day and
year first above written.
