          (a)  (i) Committed Loans.  Each Bank severally agrees, on the terms

and conditions set forth in this Agreement, to make Committed Loans to the
Borrower pursuant to this Section 2.1(a) from time to time during the Term, but

Each Committed Borrowing under this subsection (a) shall be in an aggregate
principal amount of at least $2,500,000, or an integral multiple of $1,000,000
in excess thereof, and shall be made from the several Banks ratably in

Available Facility.  Each Borrowing under this Section 2.1(a)(ii) shall be in an
aggregate principal amount of $2,500,000 or any larger multiple of $1,000,000
(except that any such Borrowing may be in the aggregate available amount of
Swing Loans determined in accordance with the immediately preceding sentence).

                                      31
<PAGE>

2.1(a)(ii), repay or, to the extent permitted by Section 2.10, prepay Swing

behalf of the Borrower (which hereby irrevocably directs the Swing Lender to act
on its behalf), on notice given by the Swing Lender no later than 1:00 P.M. (New
York City time), on the Domestic Business Day immediately following the funding
of any Swing Loan, request each Bank to make, and each Bank hereby agrees to
make, a Base Rate Loan, in an amount (with respect to each Bank, its "Swing Loan
                                                                      ----------
Refund Amount") equal to such Bank's ratable share of the aggregate Commitments
-------------
with respect to the aggregate principal amount of the Swing Loans (the "Refunded
                                                                        --------
Swing Loans") outstanding on the date of such notice, to repay the Swing Lender.
-----------
Unless any of the events described in clause (f) or (g) of Section 6.1 with
respect to the Borrower shall have occurred and be continuing (in which case the
procedures of Section 2.1(a)(iv) shall apply), each Bank shall make such Base
Rate Loan available to the Lead Agent at its address specified in or pursuant to
Section 9.1 in immediately available funds, not later than 1:00 P.M. (New York
City time), on the Domestic Business Day immediately following the date of such
notice.  The Lead Agent shall pay the proceeds of such Base Rate Loans to the
Swing Lender, which shall immediately apply such proceeds to repay Refunded
Swing Loans.  Effective on the day such Base Rate Loans are made, the portion of
the Swing Loans so paid shall no longer be outstanding as Swing Loans, shall no
longer be due as Swing Loans under the Note held by the Swing Lender, and shall
be due as Base Rate Loans under the respective Notes issued to the Banks
(including the Swing Lender) in accordance with their ratable share of the
aggregate Commitments.  The Borrower authorizes the Swing Lender to charge the
Borrower's accounts with the Lead Agent (up to the amount available in each such
account) in order to immediately pay the amount of such Refunded Swing Loans to
the extent amounts received from the Banks are not sufficient to repay in full
such Refunded Swing Loans.

          (iv)  Purchase of Participations in Swing Loans. If, prior to the time
                -----------------------------------------
Loans would have otherwise been made pursuant to Section 2.1(a)(iii), one of the
events described in clause (f) or (g) of Section 6.1 with respect to the
Borrower shall have occurred and be continuing, each Bank shall, on the date
such Loans were to have

                                      32
<PAGE>

been made pursuant to the notice referred to in Section 2.1(a)(iii) (the
"Refunding Date"), purchase an undivided participating interest in the Swing
 --------------
Loans in an amount equal to such Bank's Swing Loan Refund Amount. On the
Refunding Date, each Bank shall transfer to the Swing Lender, in immediately
available funds, such Bank's Swing Loan Refund Amount, and upon receipt thereof
the Swing Lender shall deliver to such Bank a Swing Loan participation
certificate dated the date of the Swing Lender's receipt of such funds and in
the Swing Loan Refund Amount of such Bank.

          (v)  Payments on Participated Swing Loans. Whenever, at any time after
               ------------------------------------
the Swing Lender has received from any Bank such Bank's Swing Loan Refund Amount
pursuant to Section 2.1(a)(iv), the Swing Lender receives any payment on account
of the Swing Loans in which the Banks have purchased participations pursuant to
Section 2.1(a)(iv), the Swing Lender will promptly distribute to each such Bank
its ratable share (determined on the basis of the Swing Loan Refund Amounts of
all of the Banks) of such payment (appropriately adjusted, in the case of
interest payments, to reflect the period of time during which such Bank's
participating interest was outstanding and funded); provided, however, that in
                                                    --------  -------
the event that such payment received by the Swing Lender is required to be
returned, such Bank will return to the Swing Lender any portion thereof
previously distributed to it by the Swing Lender.

          (vi) Obligations to Refund or Purchase Participations in Swing Loans
               ---------------------------------------------------------------
Absolute.  Each Bank's obligation to transfer the amount of a Loan to the Swing
--------
Lender as provided in Section 2.1(a)(iii) or to purchase a participating
interest pursuant to Section 2.1(a)(iv) shall be absolute and unconditional and
shall not be affected by any circumstance, including, without limitation, (i)
any set-off, counterclaim, recoupment, defense or other right which such Bank,
the Borrower or any other Person may have against the Swing Lender or any other
Person, other than the Swing Lender's gross negligence or willful misconduct in
connection with making any such Swing Loan, (ii) the occurrence or continuance
of a Default or an Event of Default or the termination or reduction of the
Commitments, (iii) any adverse change in the condition (financial or otherwise)
of the Borrower or any other Person, (iv) any breach of this Agreement by the
Borrower, any other Bank or any other Person, or (v) any other circumstance,
happening or event whatsoever, whether or not similar to any of the foregoing.

          (b)  Notwithstanding anything in the preceding subparagraph (a) or
elsewhere in this Agreement to the

                                      33
<PAGE>

contrary, (i) the Outstanding Balance shall in no event exceed (and no Bank
shall be deemed to have committed to fund its pro rata share of an amount which
                                              --- ----
exceeds) the lesser of (x) an amount that would result in the violation of any
provision of Section 5.8 and (y) the Available Facility and (ii) in the event
that the Swing Lender funds a Swing Loan hereunder when it has actual knowledge
that a monetary Default, material Default or material Event of Default (which,
for the avoidance of doubt shall include any violation of any provision of
Section 5.8) has occurred and is continuing, the Banks shall have the option but
not the obligation to make Base Rate Loans to fund their ratable shares of such
Swing Loan as contemplated in preceding subparagraph (a)(iii).

     Borrower, not to exceed, at such time, the Available Facility (adjusted pro
     rata for changes in the aggregate Commitments) less all Loans then
     outstanding (excluding any Loans or any portion thereof to be repaid from
     the proceeds of such Money Market Loans).  The Banks may, but shall have no
     obligation to, make such offers and the Borrower, as the case may be, may,

          any Money Market Quote so made shall be irrevocable except with the

                    ------------------
     Borrower (x) with respect to each Money Market Quote submitted in

     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 Lead Agent unless
     such subsequent Money Market Quote is submitted solely to correct a
     manifest error in such former Money Market Quote.  The Lead Agent's notice
     to the Borrower shall specify (A) the aggregate principal amount of Money
     Market Loans for which Money Market Quotes 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

     ------
     each Interest Period that are accepted, (ii) the intended use for the
     proceeds of such Money Market Borrowing, which shall be an Approved Use,
     and the total outstanding Money Market Borrowings for working capital
     purposes, and (iii) the then Unsecured Debt Ratio. The Borrower may accept
     any Money Market Quote in whole or in part; provided that:
                                                 --------

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

                    (B) the principal amount of each Money Market Borrowing must
          be $5,000,000 or a larger multiple of $500,000;

                    (C) 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

                    (D) the Borrower may not accept any Money Market Quote that
          is described in Section 2.1(c)(iv)(C) or that otherwise fails to

          Loans made on the same date of Borrowing for the same Interest Period
          shall constitute a single Borrowing.

               (vii)  Allocation by Lead Agent.  If Money Market Quotes 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 Money Market Quotes are
     permitted to be accepted for the related Interest Period, the principal
     amount of Money Market Loans in respect of which such Money Market Quotes
     are accepted shall be allocated by the Lead Agent among such Banks as
     nearly as possible (in multiples of $500,000, as the Lead Agent may deem
     appropriate) in proportion to the aggregate principal amounts of such Money
     Market Quotes.  Determinations by the Lead Agent of the amounts of Money
     Market Loans shall be conclusive in the absence of manifest error.

               (viii) Notification by Lead Agent.  Upon receipt of a Notice of

     Lead Agent shall, on the date such Notice of Money Market Borrowing is
     received by the Lead 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 such Money Market Borrowing and such Notice of Money Market
     Borrowing shall not thereafter be revocable by the Borrower.  Provided that
     the Borrower elected in the applicable Money Market Quote Request to permit
     the Banks to designate Designated Lenders to fund such Money Market Loans,
     a Bank that 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 in respect of 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 2.2. Notice of Committed Borrowing.  The Borrower shall give the
                   -----------------------------

               (ii)   the aggregate amount of such Borrowing;

               (iii)  whether the Loans comprising such Borrowing are to be Base
Rate Loans, Swing Loans or Euro-Dollar Loans;

               (iv)   in the case of a Euro-Dollar Borrowing, the duration of
the Interest Period applicable thereto, subject to the provisions of the
definition of Interest Period;

               (v)  the intended use for the proceeds of such Borrowing, which
shall be an Approved Use, and the total outstanding Borrowings for working
capital purposes; and

               (vi) the then Unsecured Debt Ratio.

          No more than two (2) Swing Loans may be borrowed during any single
calendar month.

     SECTION 2.3.  Notice to Banks; Funding of Loans.
                   ---------------------------------

          (a)  Upon receipt of a Notice of Committed Borrowing, the Lead 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 Committed
Borrowing and such Notice of Committed Borrowing shall not thereafter be
revocable by the Borrower.

          (b)  Not later than 1:00 p.m. (New York City time) on the date of each
Committed Borrowing (including, without limitation, each Swing Borrowing), each
Bank (or, in the case of a Swing Loan, the Swing Lender) shall make available
its share of such Committed Borrowing, in Federal or other funds immediately
available in New York City, to the Lead Agent at its address referred to in
Section 9.1.  Not later than 2:00 p.m. (New York City time) on the date of each
Committed Borrowing, the Lead Agent will make the funds so received from the
Banks available to the Borrower at the Lead Agent's aforesaid address.  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.

          (c)  Unless the Lead Agent shall have received notice from a Bank
prior to the date of any Committed Borrowing that such Bank will not make
available to the Lead Agent such Bank's share of such Committed Borrowing, the
Lead Agent may assume that such Bank has made such share available to the Lead
Agent on the date of such Committed Borrowing in accordance with subsection (b)
of this Section 2.3 and the Lead 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
Lead Agent, such Bank and the Borrower jointly and severally agree to repay to
the Lead 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 Lead Agent, at (i) in
the case of the Borrower, a rate per annum equal to the higher of the

                                      41
<PAGE>

Federal Funds Rate and the interest rate applicable thereto pursuant to Section
2.6 and (ii) in the case of such Bank, the Federal Funds Rate. If such Bank
shall repay to the Lead Agent such corresponding amount, such amount so repaid
shall constitute such Bank's Loan included in such Borrowing for purposes of
this Agreement.

     SECTION 2.4.   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 Lead Agent,
request that its Loans of a particular type, including Swing Loans, be evidenced
by a separate Note in an amount equal to the aggregate unpaid principal amount
of such Loans.  Each such Note shall be in substantially the form of Exhibit A-1
                                                                     -----------

                                            -----------
to any other Bank, with appropriate modifications to reflect the fact that it
evidences solely Loans of the relevant type.  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 pursuant to Section 3.1(a), the
Lead 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 that the failure of any Bank to make any such recordation
             --------
or endorsement shall not affect the obligations of the Borrower hereunder or
under the Notes.  Each Bank is hereby irrevocably authorized by the Borrower so
to endorse its Note and to attach to and make a part of its Note a continuation
of any such schedule as and when required.

          (d)  There shall be no more than seven (7) Euro-Dollar Borrowings
outstanding at any one time pursuant to this Agreement.

     SECTION 2.5.   Maturity of Loans.  The Committed Loans shall mature, and
                    -----------------
the principal amount thereof and all other Obligations shall be due and payable,

                                      42

Interest Period applicable to such Money Market Borrowing or (ii) the Maturity

principal amount thereof, for each day from the date such Loan is made until it
becomes due, at a rate per annum equal to the Base Rate for such day.  Such
interest shall be payable for each Interest Period on the last day thereof.

          (b)  Each Swing Loan shall bear interest on the outstanding principal
amount thereof at the rate applicable to Base Rate Loans, and in the case of any
amount of overdue Swing Loan, overdue interest thereon at a rate per annum for
each day equal to the sum of four percent (4%) plus the rate applicable to Base
Rate Loans for such day.

          (c)  Each Euro-Dollar Loan shall bear interest on the outstanding
principal amount thereof, for each day during the Interest Period applicable
thereto, at a rate per annum equal to the sum of the Applicable Margin for Euro-
Dollar Loans for such day plus the Adjusted London Interbank Offered Rate
applicable to such Interest Period.  Such interest shall be payable for each
Interest Period on the last day thereof and, if such Interest Period is longer
than three (3) months, at intervals of three (3) months after the first day
thereof.

Period means a rate per annum equal to the quotient obtained (rounded upward, if
necessary, to the next higher 1/10,000th of 1%) by dividing (i) the applicable
London Interbank Offered Rate by (ii) 1.00 minus the Euro-Dollar Reserve
Percentage.

          "Euro-Dollar Reserve Percentage" means for any day that percentage
           ------------------------------

liabilities which includes deposits by reference to which the interest rate on
Euro-Dollar Loans is

                                      43

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

Reserve Percentage.

Interest Period in an amount approximately equal to the principal amount of the
Euro-Dollar Loan of such Reference Bank to which such Interest Period is to
apply and for a period of time comparable to such Interest Period.

          (d)  Subject to Section 8.1, each Money Market LIBOR Loan shall bear
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
2.6(b) as if the related Money Market LIBOR Loan were a Euro-Dollar Loan) plus
(or minus) the Money Market Margin quoted by the Bank making such Loan in
accordance with Section 2.1(c).  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 2.1(c).  Such
interest shall be payable for each Interest Period on the last day thereof and,
if such Interest Period is longer than ninety (90) days, at intervals of ninety
(90) days after the first day thereof.

          (e)  In the event that, and for so long as, any Event of Default shall
have occurred and be continuing, the outstanding principal amount of the Loans
and, to the extent permitted by law, overdue interest in respect of all Loans,
shall bear interest at the annual rate of the sum of the Base Rate and four
percent (4%).

          (f)  The Lead Agent shall determine each interest rate applicable to
the Loans hereunder (other than Money Market Loans).  The Lead Agent shall give
prompt notice to the Borrower and the Banks of each rate of interest so
determined, and its determination thereof shall be conclusive in the absence of
manifest error.

The 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 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) ratings. In
the event that Borrower (or, as applicable, the Guarantor) receives more than
two (2) Borrower's Credit Ratings and such Borrower's Credit Ratings are not
equivalent, the applicable percentage shall be determined by the lower of the
two (2) highest Borrower's Credit Ratings, provided that each of such two (2)
highest Borrower's Credit Ratings shall be Investment Grade Ratings and at least
one of which shall be an Investment Grade Rating from S&P or Moody's; provided
that if neither of the two (2) highest Borrower's Credit Ratings were issued by
S&P or Moody's, the applicable percentage shall be determined by the higher of
the Borrower's Credit Ratings from S&P or Moody's.

          (b)  Fees Non-Refundable.  All fees set forth in this Section 2.7
               -------------------
shall be deemed to have been earned on the date payment is due in accordance
with the provisions hereof and shall be non-refundable.  The obligation of the
Borrower to pay such fees in accordance with the provisions hereof shall be
binding upon the Borrower and shall inure to the benefit of the Lead Agent and
the Banks regardless of whether any Loans are actually made.

     SECTION 2.8.   Mandatory Termination.
                    ---------------------

          (a)  The term (the "Term") of the Commitments and the Swing Line
                              ----
Commitments shall terminate and expire on October 24, 2003 (the "Maturity
                                                                 --------
Date"), subject, however, to the provisions of Section 2.8(b) hereof.

          (b)  The Borrower shall have one option (the "Extension Option") to
                                                        ----------------
extend the Maturity Date, for an additional twelve (12) month period, upon the
following terms and conditions:  (i) delivery by the Borrower of written notice
thereof to the Lead Agent (the "Extension Notice") on or before the date which
                                ----------------
is sixty (60) days prior to the current Maturity Date (which Extension Notice,
the Lead Agent shall promptly deliver to the Banks); (ii) no Default or Event of
Default shall have occurred and be continuing both on the date the Borrower
delivers the Extension Notice to the Lead Agent and on the first day of the
extension period (the "Extension Date"); (iii) each of the representations and
                       --------------
warranties of the Borrower contained in this Agreement (other than
representations and warranties which expressly speak of a different date) shall
be true and correct in all material respects on and as of the Extension Date;
and (iv) the Borrower shall pay to the Lead Agent, for the account of the Banks,
on the Extension Date, the Extension Fee.  Borrower's delivery of the Extension
Notice shall be irrevocable.

     SECTION 2.9.   Mandatory Prepayment.
                    --------------------

          (a)  In the event that an Unencumbered Asset Pool Property (or any
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, if less, such amount as shall
be required for the Borrower to remain in compliance with this Agreement, in the
event of a release.  Notwithstanding the foregoing, a simultaneous like-kind
exchange under Section 1031 of the Inter-

                                      46
<PAGE>

nal Revenue Code will not be subject to the provisions of this Section 2.9(a);
provided, that (i) the exchanged property has qualified as a New Acquisition,
--------
(ii) the exchanged property is not subject to any Liens (other than Permitted
Liens) and (iii) any "boot" associated therewith shall be applied to prepayment
of the Loans. Sale of an Unencumbered Asset Pool Property (or any Separate
Parcel that originally formed a part of a Unencumbered Asset Pool Property) in
violation of this Section 2.9 shall constitute an Event of Default.

          (b)  If, at any time, the Outstanding Balance shall exceed the
Available Facility, then the Borrower shall immediately prepay the Loans in an
amount equal to such excess.  Notwithstanding the foregoing, if the Outstanding
Balance exceeds an amount equal to 55.0% of the Unencumbered Asset Pool
Properties Value and no other Event of Default shall have occurred and be
continuing, then the Borrower shall, within thirty (30) days after the last day
of the preceding calendar quarter or the date of any New Acquisition resulting
in such excess (whichever is earlier), either (A) cause one (1) or more New
Acquisitions having Unencumbered Asset Pool Property Values sufficient to ensure
the Borrower's compliance with the requirements of this Agreement to be included
as Unencumbered Asset Pool Properties or (B) prepay the Loans in an amount equal
to 100% of the amount by which the Outstanding Balance exceeds the Available
Facility.

          (c)  The Borrower shall make any prepayment pursuant to this Section
2.9 together with interest accrued to the date of the prepayment on the
principal amount so prepaid; provided that any prepayment pursuant to this
Section 2.9 shall be applied (unless an Event of Default exists) as specified by
the Borrower or, otherwise, first to any Base Rate Loans then outstanding, then
to any Euro-Dollar Loans with the shortest Interest Periods.  In connection with
the prepayment of a Euro-Dollar Loan prior to the maturity thereof, the Borrower
shall also pay any applicable expenses pursuant to Section 2.12.  Each such
prepayment shall be applied to prepay ratably the Loans of the Banks.  Amounts
prepaid pursuant to this Section 2.9 may not be reborrowed unless the Borrower
shall be in compliance with the covenants set forth in Section 5.8 hereof both
before and after giving effect to any such Borrowing.

          (d)  Any event referred to in Section 2.9 that results in a required
prepayment of the Loans pursuant to this Section 2.9 shall be referred to as a
"Mandatory Prepayment Event".

     SECTION 2.10.  Optional Prepayments; Cancellation of Commitments.
                    -------------------------------------------------

          (a)  The Borrower may, upon at least one (1) Domestic Business Day's
notice to the Lead Agent, prepay to the Lead Agent, for the account of the
Banks, any Base Rate Borrowing or Swing 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 thereon to the date of prepayment.  Each
such optional prepayment shall be applied to prepay ratably the Loans of the
several Banks included in such type of 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 2.12.  Any such prepayment shall be upon at least three (3)
Euro-Dollar Business Days' notice to the Lead Agent.  Each such optional
prepayment shall be in the amounts set forth in Section 2.10(a) above and shall
be applied to prepay ratably the Loans of the Banks included.

          (c)  The Borrower may at any time and from time to time cancel all or
any part of the Commitments or Swing Line Commitments in amounts aggregating
Five Million Dollars ($5,000,000), or an integral multiple of One Million
Dollars ($1,000,000) in excess thereof, by the delivery to the Lead Agent, the
Banks and the Swing Lender of a notice of cancellation upon at least three (3)
Domestic Business Days' notice to Lead Agent, the Banks and the Swing Lender,
whereupon all or such portion of the Commitments shall terminate as to the Banks
pro rata on the date set forth in such notice of cancellation (or, in the case
--- ----
of the Swing Line Commitment, all or such portion of the Swing Line Commitment
shall terminate as to the Swing Line Lender on the date set forth in such notice
of cancellation) and, if there are any Loans or Swing Loans then outstanding in
an aggregate amount which exceeds the aggregate Commitments or Swing Line
Commitment (after giving effect to any such reduction), as applicable, the
Borrower shall prepay to the Lead Agent, for the account of the Banks or the
Swing Lender, as applicable, all or such portion of Loans or Swing Loans
outstanding on such date in accordance with the requirements of Sections 2.10(a)
and (b).  The Borrower shall be permitted to designate in its notice of
cancellation which Loans, if any, are to be prepaid.

                                      48
<PAGE>

          (d) Upon receipt of a notice of prepayment or cancellation pursuant to
this Section, the Lead 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.

          (e) Any amounts so prepaid pursuant to this Section 2.10 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 2.10(c) hereof, such amounts may not be reborrowed.

          (f) The Borrower may not prepay any Money Market Loan pursuant to this
Section 2.10 except with the prior consent of the applicable Bank or Designated
Lender, as the case may be.

     SECTION 2.11.  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 12:00 Noon (New York City
time) on the date when due, in Federal or other funds immediately available in
New York City, to the Lead Agent at its address referred to in Section 9.1.  The
Lead Agent will distribute to each Bank its ratable share of each such payment
received by the Lead Agent for the account of the Banks on the same day as
received by the Lead Agent if received by the Lead Agent by 2:00 p.m. (New York
City time) or, if received by the Lead Agent after 2:00 p.m. (New York City
time), on the immediately following Domestic Business Day.  Whenever any payment
of principal of, or interest on, the Base Rate Loans, the Money Market Absolute
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 or the Money Market LIBOR 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 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 Lead Agent shall have received notice from the Borrower
prior to the date on which any

                                      49
<PAGE>

payment is due to the Banks hereunder that the Borrower will not make such
payment in full, the Lead Agent may assume that the Borrower has made such
payment in full to the Lead Agent on such date and the Lead 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
Lead 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 Lead Agent, at the
Federal Funds Rate.

     SECTION 2.12.  Funding Losses.  If the Borrower makes any payment of
                    --------------
principal with respect to any Euro-Dollar Loan or Money Market LIBOR Loan
(pursuant to Article II, VI or VIII or otherwise) 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 or Money Market LIBOR Loans after notice has been
given to any Bank in accordance with Section 2.3(a) or 2.1(c)(vi), then the
Borrower shall reimburse each Bank within fifteen (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 2.12), including (without 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 prima facie evidence of the matters
certified therein.

     SECTION 2.13.  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 2.14.  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
Borrowing.

                                      50
<PAGE>

Thereafter, with respect to Committed Loans only, 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 and except for
any Swing Loans), 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
                                                            ------------------
Rate Election") to the Lead Agent at least three (3) Euro-Dollar Business Days
-------------
before the conversion or continuation selected in such notice is to be effective
(unless the relevant Loans are to be continued as Base Rate Loans, in which case
such notice shall be delivered to the Lead Agent no later than 12:00 Noon (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 of Loans, (ii) the portion to which such
notice applies, and the remaining portion to which it does not apply, are each
$2,500,000 or any larger multiple of $1,000,000, (iii) there shall be no more
than seven (7) Euro-Dollar Borrowings 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 of Loans are to be
     converted, the new type of Loans

                                      51
<PAGE>

     and, if such new Loans are Euro-Dollar Loans, the duration of the initial
     Interest Period applicable thereto; and

          (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 Lead 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 Lead Agent for any Group of Loans that are Euro-Dollar Loans,
such Loans shall be converted into Base Rate Loans on the last day of the then
current Interest Period applicable thereto.

may become a party to this Agreement to make the Loans, the Borrower makes the
following representations and warranties as of the date hereof.  Such
representations and warranties shall survive the effectiveness of this
Agreement, the execution and delivery of the other Loan Documents and the making
of the Loans.

     SECTION 4.1.  Existence and Power. The Borrower is duly organized, validly
                   -------------------
existing and in good standing as a limited partnership under the laws of the
State of Delaware and has all powers and all material governmental licenses,
authorizations, consents and approvals required to own its property and assets
and carry on its business as now conducted or as it presently proposes to
conduct and has been duly qualified and is in good standing in every
jurisdiction in which the failure to be so qualified and/or in good standing
would reasonably be expected to have a Material Adverse Effect.

     SECTION 4.2.  Power and Authority.  The Borrower has the power and
                   -------------------
authority to execute, deliver and carry out the terms and provisions of each of
the Loan Documents to which it is a party and has taken all necessary action to
authorize the execution and delivery on behalf of the Borrower and the
performance by the Borrower of such Loan Documents.  The Borrower has duly
executed and delivered each Loan Document to which it is a party, and each such
Loan Document constitutes the legal, valid and binding obligation of the
Borrower, enforceable in accordance with its terms, except as enforceability may
be limited by applicable insolvency, bankruptcy or other laws affecting
creditors rights generally, or general principles of equity, whether such
enforceability is considered in a proceeding in equity or at law.

     SECTION 4.3.  No Violation. Neither the execution, delivery or performance
                   ------------
by or on behalf of the Borrower of the Loan Documents to which it is a party,
nor compliance by the Borrower with the terms and provisions thereof nor the
consummation of the transactions contemplated by the Loan Documents to which it
is a party, (i) will contravene any applicable provision of any Requirement
applicable to the Borrower or (ii) will conflict with or result in any breach
of, any of the terms, covenants, conditions or provisions of, or constitute a

                                      56
<PAGE>

default under, or result in the creation or imposition of (or the obligation to
create or impose) any Lien upon any of the property or assets of the Borrower
pursuant to the terms of any material indenture, mortgage, deed of trust, or
other agreement or other instrument to which the Borrower (or of any partnership
of which the Borrower is a partner) is a party or by which it or any of its
property or assets is bound or to which it is subject or (iii) will cause a
default by the Borrower under any organizational document of any Subsidiary of
the Borrower, or cause a default under the organizational documents of the
Borrower's general partner.

     SECTION 4.4.  Financial Information.
                   ---------------------

          (a) The unaudited consolidated balance sheet of the Borrower as of
June 30, 2000, when delivered to Lead Agent shall fairly present, in conformity
with GAAP, the consolidated financial position of the Borrower as of such date.

          (b) As of the Closing Date, there has been no material adverse change
in the business, financial position or results of operations of the Borrower
since December 31, 1999.

     SECTION 4.5.  Litigation.
                   ----------

          (a) There is no action, suit or proceeding pending against, or to the
knowledge of the Borrower, threatened against or affecting, (i) the Borrower or
the Guarantor or any of their Subsidiaries, (ii) the Loan Documents or any of
the transactions contemplated by the Loan Documents or (iii) any of the assets
of the Borrower or its Subsidiaries, in any case before any court or arbitrator
or any governmental body, agency or official which would reasonably be expected
to have a Material Adverse Effect or which in any manner draws into question the
validity of this Agreement or the other Loan Documents.

          (b) There are no final nonappealable judgments or decrees in an
aggregate amount of Five Million Dollars ($5,000,000) or more entered by a court
or courts of competent jurisdiction against the Borrower or the Guarantor or any
of their Subsidiaries (other than any judgment as to which, and only to the
extent, a reputable insurance company has acknowledged coverage of such claim in
writing).

                                      57
<PAGE>

     SECTION 4.6.  Compliance with ERISA.
                   ---------------------

          (a) Except as previously disclosed to the Lead Agent in writing, each
member of the ERISA Group has fulfilled its obligations under the minimum
funding standards of ERISA and the Internal Revenue Code with respect to each
Plan and is in compliance in all material respects with the presently applicable
provisions of ERISA and the Internal Revenue Code with respect to each Plan.  No
member of the ERISA Group has (i) sought a waiver of the minimum funding
standard under Section 412 of the Internal Revenue Code in respect of any Plan,
(ii) failed to make any contribution or payment to any Plan or Multiemployer
Plan or in respect of any Benefit Arrangement, or made any amendment to any Plan
or Benefit Arrangement, which has resulted or could result in the imposition of
a Lien or the posting of a bond or other security under ERISA or the Internal
Revenue Code or (iii) incurred any liability under Title IV of ERISA other than
a liability to the PBGC for premiums under Section 4007 of ERISA.

          (b) None of the assets of any "employee benefit plan" (as such term is
defined in Section 3(3) of ERISA) has been invested in a manner that would cause
the transactions contemplated by the Loan Documents to constitute a nonexempt
prohibited transaction (as such term is defined in Section 4975 of the Internal
Revenue Code or Section 406 of ERISA).

     SECTION 4.7  Environmental Compliance.   In the ordinary course of its
                  ------------------------
business, the Borrower conducts an ongoing review of the effect of Environmental
Laws on the business, operations and properties of the Borrower and its
Consolidated Subsidiaries, including, without limitation, the Real Property
Assets, in the course of which it identifies and evaluates associated
liabilities and costs (including, without limitation, any capital or operating
expenditures required for clean-up or closure of properties presently or
previously owned, any capital or operating expenditures required to achieve or
maintain compliance with environmental protection standards imposed by law or as
a condition of any license, permit or contract, any related constraints on
operating activities, including any periodic or permanent shutdown of any
facility or reduction in the level of or change in the nature of operations
conducted thereat, any costs or liabilities in connection with off-site disposal
of Materials of Environmental Concern, and any actual or potential liabilities
to third parties, including employees, and any related costs and expenses).  On
the basis of this review, the Borrower has reasonably concluded that such
associated liabilities and costs, including the

                                      58
<PAGE>

costs of compliance with Environmental Laws, would not reasonably be expected to
have a Material Adverse Effect on the Borrower and its Consolidated
Subsidiaries.

     SECTION 4.8.  Taxes.  The initial tax year of the Borrower for federal
                   -----
income tax purposes was 1997.  The Borrower and its Subsidiaries will file all
United States Federal income tax returns and all other material tax returns
which are required to be filed by them and will pay all taxes due pursuant to
such returns or pursuant to any assessment received by the Borrower or any
Subsidiary of the Borrower except those (a) being contested in good faith or (b)
for which the non-payment of which would not reasonably be expected to have a
Material Adverse Effect.  The charges, accruals and reserves on the books of the
Borrower and its Subsidiaries in respect of taxes or other governmental charges
are, in the opinion of the Borrower, adequate.

     SECTION 4.9.  Full Disclosure.  All information (other than projections)
                   ---------------
heretofore furnished by the Borrower to the Lead Agent or any Bank for purposes
of or in connection with this Agreement or any transaction contemplated hereby
is, when taken as a whole, true and accurate in all material respects on the
date as of which such information is stated or certified.  The Borrower has
disclosed to the Banks in writing any and all facts known to the Borrower which
have or are likely to have (to the extent the Borrower can now reasonably
foresee) a Material Adverse Effect.

     SECTION 4.10.  Solvency.  On the Closing Date and after giving effect to
                    --------
the transactions contemplated by the Loan Documents occurring on the Closing
Date, the Borrower is Solvent.

     SECTION 4.11.  Use of Proceeds; Margin Regulations.  All proceeds of the
                    -----------------------------------
Loans will be used by the Borrower only for Approved Uses.  No part of the
proceeds of any Loan will be used by the Borrower to purchase or carry any
Margin Stock or to extend credit to others for the purpose of purchasing or
carrying any Margin Stock.  Neither the making of any Loan nor the use of the
proceeds thereof will violate or be inconsistent with the provisions of
Regulations T, U or X of the Federal Reserve Board.

     SECTION 4.12.  Governmental Approvals.  No order, consent, approval,
                    ----------------------
license, authorization, or validation of, or filing, recording or registration
with, or exemption by, any Governmental Authority is required to authorize, or
is required in connection with the execution, delivery and performance of any
Loan Document or the

                                      59
<PAGE>

consummation of any of the transactions contemplated thereby other than those
(a) that have already been duly made or obtained and remain in full force and
effect or (b) the failure of which to obtain would not reasonably be expected to
have a Material Adverse Effect.

     SECTION 4.13.  Investment Company Act; Public Utility Holding Company Act.
                    ----------------------------------------------------------
The Borrower is not (x) an "investment company" or a company "controlled" by an
"investment company", within the meaning of the Investment Company Act of 1940,
as amended, (y) a "holding company" or a "subsidiary company" of a "holding
company" or an "affiliate" of either a "holding company" or a "subsidiary
company" within the meaning of the Public Utility Holding Company Act of 1935,
as amended, or (z) subject to any other Requirement which purports to restrict
or regulate its ability to borrow money.

     SECTION 4.14.  Closing Date Transactions.  On the Closing Date and
                    -------------------------
immediately prior to or concurrently with the making of the Loans, the
transactions (other than the making of the Loans) intended to be consummated on
the Closing Date will have been consummated in accordance with all applicable
laws.  On or prior to the Closing Date, all consents and approvals of, and
filings and registrations with, and all other actions by, any Person required in
order to make or consummate such transactions have been obtained, given, filed
or taken and are in full force and effect, other than those the failure of which
to obtain would not reasonably be expected to have a Material Adverse Effect.

     SECTION 4.15.  Representations and Warranties in Loan Documents.  All
                    ------------------------------------------------
representations and warranties made by the Borrower in the Loan Documents are
true and correct in all material respects.

     SECTION 4.16.  Patents, Trademarks, etc.  The Borrower has obtained and
                    -------------------------
holds in full force and effect all patents, trademarks, service marks, trade
names, copyrights and other such rights, free from burdensome restrictions,
which are necessary for the operation of its business as presently conducted,
the impairment of which would reasonably be expected to have a Material Adverse
Effect.  To the Borrower's knowledge, no material product, process, method,
substance, part or other material presently sold by or employed by the Borrower
in connection with such business infringes any patent, trademark, service mark,
trade name, copyright, license or other such right owned by any other Person.
There is not pending or, to the Borrower's knowledge, overtly threatened any
claim or litigation against or affecting the Borrower contesting its right to
sell or use any such

                                      60

product, process, method, substance, part or other material.

     SECTION 4.17.  No Default.  No Default or Event of Default exists under or

with respect to any Loan Document.  The Borrower is not in default in any
material respect beyond any applicable grace period under or with respect to any
other material agreement, instrument or undertaking to which it is a party or by
which it or any of its property is bound in any respect, the existence of which
default would reasonably be expected to result in a Material Adverse Effect.

     SECTION 4.18.  Licenses, etc.  The Borrower has obtained and holds in full
                    --------------
force and effect, all franchises, licenses, permits, certificates,
authorizations, qualifications, accreditations, easements, rights of way and
other consents and approvals which are necessary for the operation of its
businesses as presently conducted, the absence of which would reasonably be
expected to have a Material Adverse Effect.

     SECTION 4.19.  Compliance With Law.  The Borrower is in compliance with
                    -------------------
all laws, rules, regulations, orders, judgments, writs and decrees, including,
without limitation, all building and zoning ordinances and codes, the failure to
comply with which would reasonably be expected to have a Material Adverse
Effect.

     SECTION 4.20.  No Burdensome Restrictions.  The Borrower is not a party to
                    --------------------------
any agreement or instrument or subject to any other obligation or any charter or
corporate or partnership restriction, as the case may be, which, individually or
in the aggregate, would reasonably be expected to have a Material Adverse
Effect.

     SECTION 4.21.  Brokers' Fees.  The Borrower has not dealt with any broker
                    -------------
or finder with respect to the transactions contemplated by the Loan Documents
(except with respect to the acquisition or disposition of Real Property Assets)
or otherwise in connection with this Agreement, and the Borrower has not done
any acts, had any negotiations or conversations, or made any agreements or
promises which will in any way create or give rise to any obligation or
liability for the payment by the Borrower of any brokerage fee, charge,
commission or other compensation to any party with respect to the transactions
contemplated by the Loan Documents (except with respect to the acquisition or
disposition of Real Property Assets), other than the fees payable hereunder.

     SECTION 4.22.  Labor Matters.  There are no collective bargaining
                    -------------

purpose, (ii) for other purposes related to the acquisition of such properties
(including, without limitation, the payment of fees and other costs related to
such acquisition), (iii) for construction and development related purposes, or

borrowed monies or any other Lien (except for Permitted Liens) on or with
respect to any Unencumbered Asset Pool Property, unless the same is being
contested in good faith or the same is discharged, bonded off or paid within

in all respects and (b) assuming the sale, transfer or conveyance is actually
consummated, to the actual knowledge of such officer, no Default or Event of
Default under any other provision of Section 6.1 has occurred and is then
continuing.  In the event that a Separate Parcel that originally formed a part
of a Unencumbered Asset Pool Property is to be released from the terms of this
Agreement and Borrower otherwise complies with the provisions hereof with
respect thereto, the value of such Separate Parcel (and the remaining portion of
the Unencumbered Asset Pool  Property) will be determined by Lead Agent at the

all of the covenants contained in Sections 5.8, 5.9, 5.16 and 5.17 are and after
giving effect to the transaction shall continue to be true and accurate in all
respects, and (iii) pay to the Agent an amount equal to that re-

                                      73

restoration following a casualty or condemnation of existing improvements on
Real Property Assets) in excess of twenty percent (20%) of Tangible FMV.

hereby expressly waived by the Borrower; and upon the occurrence and during the
continuance of any other Event of Default, the Lead Agent may (and shall, at the
instruction of the Required Banks) exercise any of its rights and remedies
hereunder and by written notice to the Borrower, 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.

     SECTION 6.3.   Notice of Default.  If the Lead Agent shall not already have
                    -----------------
given any notice to the Borrower under Section 6.1, the Lead 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.  Upon
obtaining actual knowledge of a Default, the Lead Agent and each Bank, as
applicable, shall promptly deliver written notice thereof to, in the case of the
Lead Agent's obtaining such knowledge, the other Banks, and in the case of a
Bank's obtaining such knowledge, to the Lead Agent which will then deliver
written notice to the other Banks.


                                  ARTICLE VII

                                THE LEAD AGENT

     SECTION 7.1.   Appointment and Authorization.  Each Bank irrevocably
                    -----------------------------
appoints and authorizes the Lead 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 Lead Agent by the terms hereof or thereof,
together with all such powers as are reasonably incidental thereto.  For the
avoidance of doubt, "Documentation Agent" is merely a title hereunder, and the
Bank that is the Documentation Agent shall have

                                      78
<PAGE>

no duties or obligations hereunder in its capacity as such, but shall have only
those duties and obligations applicable to it in its capacity as a Bank
hereunder.

     SECTION 7.2.  Lead Agent and Affiliates.  Morgan 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 Lead Agent, and
Morgan 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 Lead Agent hereunder, and the term "Bank"
and "Banks" shall include Morgan in its individual capacity.

     SECTION 7.3.  Action by Lead Agent.  The obligations of the Lead Agent
                   --------------------
hereunder are only those expressly set forth herein.  Without limiting the
generality of the foregoing, the Lead Agent shall not be required to take any
action with respect to any Default, except as expressly provided in Article VI.

     SECTION 7.4.  Consultation with Experts. The Lead 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 7.5.  Liability of Lead Agent.  Neither the Lead 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 Lead
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 Lead 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 Lead 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

                                      79
<PAGE>

writing) believed by it in good faith to be genuine or to be signed by the
proper party or parties.

     SECTION 7.6.  Indemnification.  Each Bank shall, ratably in accordance
                   ---------------
with its Commitment, indemnify the Lead 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 in connection with this Agreement, the other
Loan Documents or any action taken or omitted by such indemnitees hereunder.

     SECTION 7.7.  Credit Decision.  Each Bank acknowledges that it has,
                   ---------------
independently and without reliance upon the Lead 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 Lead
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 7.8.  Successor Lead Agent.  The Lead Agent may resign at any
                   --------------------
time by giving notice thereof to the Banks and the Borrower.  In addition, the
Super-Required Banks may remove the Lead Agent in the event of the Lead's
Agent's gross negligence or willful misconduct in the performance of its duties
as Lead Agent hereunder.  Upon any such resignation or removal of the Lead
Agent, the Required Banks shall have the right to appoint a successor Lead Agent
with the consent of the Borrower provided that no Event of Default shall have
occurred and be continuing.  If in the case of a resigning Lead Agent no
successor Lead Agent shall have been so appointed by the Required Banks, and
shall have accepted such appointment, within 30 days after the retiring Lead
Agent gives notice of resignation, then the retiring Lead Agent may, on behalf
of the Banks, appoint a successor Lead Agent, which shall be a commercial bank
organized or licensed under the laws of the United States or of any State
thereof and having a combined capital and surplus of at least $50,000,000.  Upon
the acceptance of its appointment as the Lead Agent hereunder by a successor
Lead Agent, such successor Lead Agent shall thereupon succeed to and become
vested with all the rights and duties of the retiring Lead Agent, and the
retiring Lead Agent shall be discharged from its duties and obligations

                                      80
<PAGE>

hereunder first accruing or arising after the effective date of such retirement.
After any retiring Lead Agent's resignation or removal hereunder as Lead 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 Lead Agent.

     SECTION 7.9.   Lead Agent's Fee.  The Borrower shall pay to the Lead Agent
                    ----------------
for its own account fees in the amounts and at the times previously agreed upon
between the Borrower and the Lead Agent.

     SECTION 7.10.  Copies of Notices.  Lead Agent shall deliver to each Bank
                    -----------------
a copy of any notice sent to the Borrower by Lead Agent in connection with the
performance of its duties as Lead Agent hereunder.


                                 ARTICLE VIII

                            CHANGE IN CIRCUMSTANCES

     SECTION 8.1.   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 LIBOR Borrowing:

     (a) the Lead 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 Commitments in
the case of Euro-Dollar Loans or the applicable Bank or Designated Lender, as
the case may be, in the case of Money Market LIBOR Loans, advise the Lead Agent
that the Adjusted London Interbank Offered Rate as determined by the Lead Agent
will not adequately and fairly reflect the cost to such Banks of funding their
Euro-Dollar Loans or Money Market LIBOR Loans, as the case may be, for such
Interest Period,

then the Lead Agent shall forthwith give notice thereof to the Borrower and the
Banks, whereupon until the Lead 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 Money Market LIBOR Loans, as the case may
be, shall be suspended.  Unless the Borrower notifies the Lead Agent at least
two (2) 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

                                      81
<PAGE>

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 8.2.  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 or Money Market
Lending Office, as the case may be) with any request or directive (whether or
not having the force of law) of any such Governmental Authority, central bank or
comparable agency shall make it unlawful or impossible for any Bank (or its
Euro-Dollar Lending Office or Money Market Lending Office, as the case may be)
to make, maintain or fund its Euro-Dollar Loans or Money Market LIBOR Loans, and
such Bank shall so notify the Lead Agent, the Lead Agent shall forthwith give
notice thereof to the other Banks and the Borrower, whereupon until such Bank
notifies the Borrower and the Lead Agent that the circumstances giving rise to
such suspension no longer exist, the obligation of such Bank to make Euro-Dollar
Loans or Money Market LIBOR Loans shall be suspended.  With respect to Euro-
Dollar Loans or Money Market LIBOR Loans, before giving any notice to the Lead
Agent pursuant to this Section, such Bank shall designate a different Euro-
Dollar Lending Office or Money Market Lending Office, as the case may be, 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 LIBOR Loans (as the case may
be) to maturity and shall so 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 LIBOR Loan, together with accrued interest
thereon.  Concurrently with prepaying each such Euro-Dollar Loan or Money Market
LIBOR 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 LIBOR Loan
of the other Banks), and such Bank shall make such a Base Rate Loan.

                                      82
<PAGE>

     SECTION 8.3.  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 applicable 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 Governmental 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 or Money Market LIBOR 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 Money Market LIBOR
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
fifteen (15) days after demand by such Bank (with a copy to the Lead Agent),
which demand shall be accompanied by a certificate showing, in reasonable
detail, the calculation of such amount or amounts, and provided such Bank is
generally exercising rights similar to those set forth in this Section 8.3(a)
against other borrowers similarly situated to the Borrower, the Borrower shall
pay to such Bank such additional amount or amounts as will compensate such Bank
for such increased cost or reduction.

     (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

                                      83
<PAGE>

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
Governmental 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 fifteen (15) days after demand by such Bank (with a copy to
the Lead Agent), which demand shall be accompanied by a certificate showing, in
reasonable detail, the calculation of such amount or amounts, and provided such
Bank is generally exercising rights similar to those set forth in this Section
8.3(b) against other borrowers similarly situated to the Borrower, 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 Lead 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 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 prima facie evidence of the
matters certified therein.  In determining such amount, such Bank may use any
reasonable averaging and attribution methods.

     SECTION 8.4.  Taxes.
                   -----

     (a) Any and all payments by the Borrower to or for the account of any Bank
or the Lead 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 with respect thereto, excluding, in the case of each Bank and the
                                  ---------
Lead Agent, taxes imposed on its income, and franchise taxes imposed on it, by
the jurisdiction under the laws of which such Bank or the Lead 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

                                      84
<PAGE>

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 participation therein to any Bank or the Lead 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 or the Lead 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 Lead
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
participation therein or from the execution or delivery of, or otherwise with
respect to, this Agreement or any Note or participation therein (hereinafter
referred to as "Other Taxes").
                -----------

     (c) The Borrower agrees to indemnify each Bank and the Lead 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 or the Lead Agent (as the case may be) and
any liability (including penalties, interest and expenses) arising therefrom or
with respect thereto.  Any payment required under this indemnification shall be
made within fifteen (15) days from the date such Bank or the Lead Agent (as the
case may be) makes demand therefor.

     (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

                                      85
<PAGE>

do so), shall provide the Borrower with Internal Revenue Service forms W-8ECI or
W-8BEN, 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 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 (i) such Bank will change
the

                                      86
<PAGE>

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 or (ii) in
the event that such Bank shall fail or refuse to change the jurisdiction of its
Applicable Lending Office within twenty (20) Domestic Business Days after
written notice from the Borrower and no Event of Default shall then exist, the
Borrower shall have the right to either (A) designate an Assignee for such Bank,
which Bank shall assign and transfer to such Assignee all of such Bank's rights
and obligations under this Agreement at a purchase price mutually acceptable to
such Bank and such Assignee or (B) prepay the principal amount outstanding under
the  Note held by such Bank, together with all accrued and unpaid interest
thereon and all other sums owed by Borrower to such Bank hereunder or under the
Loan Documents, whereupon the Commitment of such Bank shall be reduced to zero.

     SECTION 8.5.  Base Rate Loans Substituted for Affected Euro-Dollar Loans.
                   ----------------------------------------------------
If (i) the obligation of any Bank to make 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 Lead 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.

                                  ARTICLE IX

under Article II or Article VIII shall not be effective until received.

     SECTION 9.2.  No Waivers.  No failure or delay by the Lead Agent or any
                   ----------
Bank in exercising any right, power or privilege hereunder or under any Note
shall operate as a waiver thereof nor shall any single or partial exercise
thereof preclude any other or further exercise thereof or the exercise of any
other right, power or privilege.  The rights and remedies herein provided shall
be cumulative and not exclusive of any rights or remedies provided by law.

     SECTION 9.3.  Expenses; Indemnification.
                   -------------------------

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

their respective Affiliates and the respective directors, officers, agents and
employees of the foregoing (each an "Indemnitee") and hold each Indemnitee
                                     ----------
harmless from and against any and all liabilities, losses, damages, costs and
expenses of any kind, including, without limitation, the 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 operation of property or assets by the
Borrower or any of the Environmental Affiliates, including, without limitation,
all on-site and off-site activities involving Material of Environmental Concern,
(iv) the breach of any environmental representation or warranty set forth
herein, (v) the grant to the Lead Agent and the Banks of any Lien in any
property or assets of the Borrower or any stock or other equity interest in the
Borrower, and (vi) the exercise by the Lead Agent and the Banks of their rights
and remedies (including, without limitation, foreclosure) under any agreements
creating any such Lien (but excluding, as to any Indemnitee, any such losses,
liabilities, claims, damages, expenses, obligations, penalties, actions,
judgments, suits, costs or disbursements to the extent incurred by reason of (i)
the gross negligence or willful misconduct of such Indemnitee as finally
determined by a court of competent jurisdiction or (ii) 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

                                      89
<PAGE>

under this Section shall survive the termination of this Agreement and the
payment of the Obligations.

          (c) The Borrower shall pay, and hold the Lead Agent and each of the
Banks harmless from and against, any and all present and future United States
stamp,  intangible, recording, transfer and other similar taxes with respect to
the foregoing matters and hold the Lead 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 9.4.  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 which
is greater than the proportion received by any 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, 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 shall be
shared by the Banks pro rata; provided that nothing in this Section shall impair
                    --- ----  --------
the right 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.  The
Borrower agrees, to the fullest extent that it may effectively do so under
applicable law, that any holder of a participation in a

                                      90
<PAGE>

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 9.5.  Amendments and Waivers.  Any provision of this Agreement,
                   ----------------------
the Notes 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 Lead Agent are affected thereby, by
the Lead 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) or subject any Bank to
any additional obligation except pursuant to the terms of Section 9.14 hereof,
(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) change the percentage of the Commitments or
of the aggregate unpaid principal amount of the Notes, or the number of Banks
that shall be required for the Banks or any of them to take any action under
this Section or any other provision of this Agreement (including, without
limitation, amending the definitions of "Super-Required Banks" or "Required
Banks" hereunder), (v) release the Guarantor from any of its obligations under
the Guaranty or (vi) amend or modify any of the provisions of this Section 9.5.
In addition, no such amendment or waiver shall, unless signed by the Swing
Lender and each other Bank affected thereby, increase the Swing Loan Commitment,
postpone the date fixed for the termination of the Swing Loan Commitment or
otherwise affect any of its rights or obligations hereunder relating to the
Swing Loan Commitment or the Swing Loans.

     SECTION 9.6.  Successors and Assigns.
                   ----------------------

          (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
institutions (each a "Participant") participating interests in its Commitment or
                      -----------
any or all

                                      91
<PAGE>

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
Lead Agent, such Bank shall remain responsible for the performance of its
obligations hereunder, and the Borrower and the Lead 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 (in
                       --------
minimum amounts of not less than Five Million Dollars ($5,000,000) and integral
multiple of One Million Dollars ($1,000,000) thereafter), 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 C
                                                                 ---------
attached hereto executed by such Assignee and such transferor Bank, with (and
subject to) the consent of the Lead Agent and, provided no Event of Default
shall have occurred and be continuing, the Borrower, which consent in either
case 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 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 trans-

                                      92
<PAGE>

feror Bank, the Lead 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, the transferor Bank shall pay to the Lead
Agent an administrative fee for processing such assignment in the amount of
$2,500. If the Assignee is not incorporated under the laws of the United States
or a state thereof, it shall deliver to the Borrower and the Lead 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 at a time.  The parties to each
such designation shall execute and deliver to the Lead Agent for its acceptance
a Designation Agreement in the form of Exhibit G hereto.  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 Lead
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
Designated Lender 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 2.1(c)) to make
Money Market Loans on behalf of its Designating Lender pursuant to Section
2.1(c) 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, the Agents 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 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 Desig-

                                      93
<PAGE>

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

          (e) Any Bank may at any time assign all or any portion of its rights
under this Agreement and its Note 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.

          (g) Any Bank may, in connection with any assignment or participation
or proposed assignment or participation pursuant to this Section 9.6, disclose
to the assignee or participant or proposed assignee or participant, any
information relating to the Borrower,

                                      94
<PAGE>

the Guarantor or any of their respective Affiliates furnished to such Bank by
the Lead Agent or by or on behalf of the Borrower, the Guarantor or any of their
respective Affiliates (the "Information"). Each of the Lead Agent and the Banks
                            -----------
agrees to maintain the confidentiality of the Information, except that
Information may be disclosed (a) upon the occurrence and during the continuance
of an Event of Default, (b) to its and its Affiliates' directors, officers,
employees and agents, including accountants, legal counsel, and other advisors
(it being understood that the Persons to whom such disclosure is made will be
informed of the confidential nature of such Information and instructed to keep
such Information confidential), (c) to the extent requested by any regulatory
authority, (d) to the extent required by applicable laws or regulations or by
any subpoena or similar legal process, (e) to any other party to this Agreement,
(f) in connection with the exercise of any remedies hereunder or any suit,
action or proceeding relating to this Agreement or the enforcement of rights
hereunder, (g) subject to an agreement containing provisions substantially the
same as those of this paragraph, to any assignee or participant in, or
prospective assignee of, or participant in, any of its rights or obligations
under this Agreement, (h) with the consent of the Borrower, not to be
unreasonably withheld, or (i) to the extent that such Information (x) becomes
publicly available other than as a result of a breach of this paragraph, or (y)
becomes available to the Lead Agent or any Bank on a non-confidential basis from
a source other than the Borrower.

     SECTION 9.7.  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).

     (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 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

                                      95

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
Lead 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 9.8.  Marshaling; Recapture.  Neither the Lead 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 the
Bankruptcy Code or any other 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.

                   ----------------------------------------
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 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 Lead 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 Lead
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).
<PAGE>

     SECTION 9.10.  WAIVER OF JURY TRIAL.  EACH OF THE BORROWER, THE LEAD 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 9.11.  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.

                    -----------------
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 9.13.  Limitation of Liability.  No claim may be made by the
                    -----------------------
Borrower or any other Person against the Lead 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 9.14.  Additional Commitment.
                    ---------------------

          (a) Borrower shall have a one time right to request that the Lead
Agent obtain additional Commitments (the "Subsequent Additional Commitments") so
                                          ---------------------------------
that the Maximum Facility Amount is equal to an amount up to Three Hundred
Seventy-Five Million Dollars ($375,000,000) (such amount, the "Target Facility
                                                               ---------------
Amount"), which request shall be made by the Borrower giving written notice (the
------
"Subsequent Additional Commitment Notice") to the Lead Agent at least thirty
 ---------------------------------------
(30) days prior to the date that is the eighteenth month anniversary of the
Closing Date (the "Syndication Expiration Date") setting forth such details with
                   ---------------------------
respect thereto as are reasonably requested by the Lead Agent (including,
without limitation, the amount (the "Subsequent Additional Commitment Amount")
                                     ---------------------------------------
by which the Maximum Facility Amount is to be increased).  Upon receipt of such
request, the Lead Agent shall use its best efforts, with the assistance of the
Borrower, to arrange a syndicate of Banks with Commitments (including the
Initial Commitments), aggregating the Target Facility Amount on or before the
Syndication Expiration Date.

                                      97
<PAGE>

Notwithstanding anything to the contrary contained herein no Bank shall be
obligated to increase the amount of its Commitment to an amount that is greater
than such Bank's Initial Commitment.

          (b) Subsequent Additional Commitments shall be offered pro rata to the
Banks party hereto as of the date of the Subsequent Additional Commitment
Notice.  Each Bank (each, an "Accepting Bank") that accepts such additional
                              --------------
amount within fifteen (15) days after receipt of an offer from the Lead Agent
therefor may increase its Commitment by a maximum amount (each, a "Commitment
                                                                   ----------
Increase") equal to the product of (x) the Subsequent Additional Commitment
--------
Amount times (y) the percentage that such Bank's Initial Commitment bears to the
Available Facility as of the Closing Date.  If any Bank (each, a "Declining
                                                                  ---------
Bank") shall not accept such additional amount within fifteen (15) days after
----
receipt of an offer therefor from the Lead Agent, (i) such Declining Bank's
Commitment shall remain at an amount equal to its Initial Commitment and (ii)
the Borrower may request (x) any Accepting Bank to further increase its
Commitment by an amount equal to all or any portion of an aggregate amount equal
to each Declining Bank's Commitment Increase or (y) the Lead Agent to submit a
list of proposed bank syndicate members that are not party to this Agreement as
of the date of such request to the Borrower for its review and approval (which
approval shall not be unreasonably withheld or delayed) in order to obtain
additional Commitments such that the Maximum Facility Amount is equal to the
Target Facility Amount; provided, however, notwithstanding anything to the
                        --------  -------
contrary contained herein, (i) no Bank shall be obligated to increase the amount
of its Commitment to an amount that is greater than such Bank's Initial
Commitment and (ii) the Banks shall not be obligated to increase the Maximum
Facility Amount to an amount that is greater than the Maximum Facility Amount as
of the Closing Date.  From and after the Syndication Expiration Date, the Lead
Agent shall have no further obligation to syndicate the Facility or to obtain or
accept any additional Commitments.
