reference to the pricing of Loans comprising such Borrowing (e.g., a "Euro-
                                                             ----
Dollar Borrowing" is a Borrowing comprised of Euro-Dollar Loans) or by reference
to the provisions of Article II under which participation therein is determined

          (a) Each Bank severally agrees, on the terms and conditions set forth
in this Agreement, to make Committed Loans to the Borrower and participate in
Letters of Credit issued by the Fronting Bank on behalf of the Borrower pursuant
to this Section from time to time during the Term in amounts such that the
aggregate principal amount of Committed Loans by such Bank at any one time
outstanding together with such Bank's pro rata share of the Letter of Credit
                                      --- ----
Usage shall not exceed the amount of its Commitment.  The aggregate amount of
Committed Loans to be made hereunder together with the Letter of Credit Usage
and outstanding Money Market Loans shall not exceed Four Hundred Million Dollars
($400,000,000) (the "Loan Amount").  Each Borrowing
                     -----------


                                       38

$2,500,000, or an integral multiple of $500,000 in excess thereof and shall be
made from the several Banks ratably in proportion to their respective
Commitments. Subject to the limitations set forth herein, any amounts repaid may
be reborrowed. Notwithstanding anything to the contrary, the number of new
Borrowings shall be limited to ten (10) Borrowings per month.

          (b) Notwithstanding anything in the preceding subparagraph (a) to the
contrary, the Loan Amount 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) an
                              --- ----
amount that would cause (A) the ratio of (i) Unencumbered Asset Pool Net
Operating Cash Flow to (ii) Pro-Forma Debt Service to be less than 2.0:1.0 or
(B) the Unsecured Debt Ratio to be less than 2.0:1.0 or (C) an amount which
would result in the violation of any provision of Section 5.8.

          Section II.2.  Notice of Committed Borrowing.  (a)  The Borrower shall
                         -----------------------------
give the Lead Agent notice (a "Notice of Committed Borrowing") not later than
                               -----------------------------

                                       39

     Rate Loans or Euro-Dollar Loans,

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

     and

               (6)  that no Default or Event of Default has occurred or is
     continuing.

Notwithstanding the time frame set forth in clause (a)(x) above, in the event
that the Money Market Quotes submitted by the Banks pursuant to Section 2.3(c)
below are, in the aggregate, in an amount less than the principal amount
requested by the Borrower in the related Money Market Quote Request, then the
Borrower shall be permitted to give the Lead Agent notice of its intent to make
a Base Rate Borrowing, in the amount of the difference between accepted Money
Market Quotes and the principal amount requested by Borrower in the related
Money Market Quote Request, no later than 2:30 p.m. (New York City time) on the
date of such Borrowing.

          (b) Borrower shall give the Lead Agent, and the designated Fronting

such notice may be revoked telephonically by the Borrower to the applicable
Fronting Bank and the Lead Agent any time prior to the date of issuance of the
Letter of Credit by the applicable Fronting Bank, provided such revocation is
confirmed in writing by the Borrower to the Fronting Bank and the Lead Agent
within one (1) Domestic Business Day by facsimile. No later than 2:00 p.m., New
York City time, on the date that is four (4) Domestic Business Days prior to the
date of issuance, the Borrower shall specify a precise description of the
documents and the verbatim text of any certificate to be presented by the
beneficiary of such Letter of Credit, which if presented by such beneficiary
prior to the expiration date of the Letter of Credit would require the Fronting
Bank to make a payment under the Letter of Credit; provided, that Fronting Bank
                                                   --------
may, in its reasonable judgment, require changes in any such documents and
certificates only in conformity with changes in customary and commercially
reasonable practice or law and, provided further, that no Letter of Credit shall
                                -------- -------
require payment against a conforming draft to be made thereunder on the
following Domestic Business Day that such draft is presented if such
presentation is made later than 10:00 A.M. New York City time (except that if
the beneficiary of any Letter of Credit requests at the time of the issuance of
its Letter of Credit that payment be made on the same Domestic Business Day
against a conforming draft, such beneficiary shall be entitled to such a same
day draw, provided such draft is

                                       41


presented to the applicable Fronting Bank no later than 10:00 A.M. New York City
time and provided further the Borrower shall have requested to the Fronting Bank
and the Lead Agent that such beneficiary shall be entitled to a same day draw).
In determining whether to pay on such Letter of Credit, the Fronting Bank shall
be responsible only to determine that the documents and certificates required to
be delivered under the Letter of Credit have been delivered and that they comply
on their face with the requirements of that Letter of Credit.

          Section II.3.  Money Market Borrowings.
                         -----------------------

Banks during the Term to make offers to make Money Market Loans to the Borrower,
not to exceed, at such time, the lesser of (i) the Committed Loans and (ii)
$150,000,000.  The Banks may, but shall have no obligation to, make such offers
and the Borrower may, but shall have no obligation to, accept any such offers in
the manner set forth in this Section.

the Borrower and the Lead Agent shall have mutually agreed and shall have
notified to the Banks not later than the date of the Money Market Quote Request
for the first LIBOR Auction or Absolute Rate Auction for which such change is to
be effective) specifying:

                    (i)   the proposed date of Borrowing, which shall be a Euro-
          Dollar Business Day in the case of a LIBOR Auction or a Domestic

          $10,000,000 or a larger multiple of $500,000,

                    (iii) the duration of the Interest Period applicable
          thereto, subject to the provisions of the definition of Interest
          Period, and

                    (iv)  whether the Money Market Quotes requested are to set
          forth a Money Market Margin or a Money Market Absolute Rate.

The Borrower may request offers to make Money Market Loans for more than one
Interest Period in a single Money Market Quote Request. No Money Market Quote

the Lead Agent or such affiliate notifies the Borrower of the terms of the offer
or offers contained therein not later than thirty (30) minutes prior to the
applicable deadline for the other Banks.  Subject to Articles III and VI, any
Money Market Quote so made shall be irrevocable except with the written consent
of the Lead Agent given on the instructions of the Borrower.  Such Money Market
Loans may be funded by such Bank's Designated Lender (if any) as provided in
Section 9.6(d); however such Bank shall not be required to specify in its Money
Market Quote whether such Money Market Loans will be funded by such Designated
Lender.

               (ii)  Each Money Market Quote shall be in substantially the form
of Exhibit E hereto and shall in any case specify:
   ---------

     larger multiple of $500,000, (y) may not exceed the principal amount of
     Money Market Loans for which offers were requested and (z) may be subject
     to an aggregate limitation as to the principal amount of Money Market Loans
     for which offers being made by such quoting Bank may be accepted,

               (3)  in the case of a LIBOR Auction, the margin above or below
     the applicable London Interbank Offered Rate (the "Money Market Margin")

     from such base rate,

               (4)  in the case of an Absolute Rate Auction, the rate of
     interest per annum (specified to the nearest 1/10,000th of 1%) (the "Money

 A Money Market Quote may set forth up to five separate offers by the quoting
 Bank with respect to each Interest Period specified in the related Invitation
 for Money Market Quotes.

        (iii)  Any Money Market Quote shall be disregarded if it:

                                       45


               (1)  is not substantially in conformity with Exhibit F hereto or
                                                            ---------
     does not specify all of the information required by subsection (d)(ii)
     above;

               (2)  contains qualifying, conditional or similar language;

               (3)  proposes terms other than or in addition to those set forth
     in the applicable Invitation for Money Market Quotes; or

               (4)  arrives after the time set forth in subsection (d)(i).

          (e)  Notice to Borrower.  The Lead Agent shall promptly notify the
               ------------------
Borrower (x) with respect to each Money Market Quote submitted in accordance

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 offers have been received for each Interest Period
specified in the related Money Market Quote Request, (B) the respective
principal amounts and Money Market Margins or Money Market Absolute Rates, as
the case may be, so offered and (C) if applicable, limitations on the aggregate
principal amount of Money Market Loans for which offers in any single Money
Market Quote may be accepted.

                                       46


          (f) Acceptance and Notice by Borrower.  Not later than 1:00 p.m. (New
              ---------------------------------
York City time) on (x) the third Euro-Dollar Business Day prior to the proposed
date of Borrowing, in the case of a LIBOR Auction, or (y) the proposed date of
Borrowing, in the case of an Absolute Rate Auction (or, in either case, such
other time or date as the Borrower and the Lead Agent shall have mutually agreed
and shall have notified to the Banks not later than the date of the Money Market
Quote Request for the first LIBOR Auction or Absolute Rate Auction for which
such change is to be effective), the Borrower shall notify the Lead Agent of its
acceptance or non-acceptance of the offers so notified to it pursuant to
subsection (e).  In the case of acceptance, such notice (a "Notice of Money
                                                            ---------------
Market Borrowing") shall specify the aggregate principal amount of offers for
- ----------------
each Interest Period that are accepted.  The Borrower may accept any Money
Market Quote in whole or in part; provided that:
                                  --------

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

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

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

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

                                       47


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

          (h) Notification by Lead Agent.  Upon receipt of the Borrower's Notice
              --------------------------
of Money Market Borrowing in accordance with Section 2.3(f) hereof, the 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. A Bank who is notified that it has been
selected to make a Money Market Loan may designate its Designated Lender (if
any) to fund such Money Market Loan on its behalf, as described in Section
9.6(d).  Any Designated Lender which funds a Money Market Loan shall on and
after the time of such funding become the obligee under such Money Market Loan
and be entitled to receive payment thereof when due.  No Bank shall be relieved
of its obligation to fund a Money Market Loan, and no Designated Lender shall
assume such obligation, prior to the time the applicable Money Market Loan is
funded.

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

                                       48


          (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 Borrowing and
such Notice of Committed Borrowing shall not thereafter be revocable by the
Borrower.

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

                                       49


have the primary obligation to fund any and all draws made with respect to such
Letter of Credit notwithstanding any failure of a participating Bank to fund its
ratable share of any such draw. The Lead Agent will instruct the Fronting Bank
to make such Letter of Credit available to the Borrower and the Fronting Bank
shall make such Letter of Credit available to the Borrower at the Borrower's
aforesaid address or at such address in the United States as Borrower shall
request on the date of the Borrowing.

          (c) Unless the Lead Agent shall have received notice from a Bank prior
to the date of any Borrowing that such Bank will not make available to the Lead
Agent such Bank's share of such Borrowing, the Lead Agent may assume that such
Bank has made such share available to the Lead Agent on the date of such
Borrowing in accordance with subsection (b) of this Section 2.4 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
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 Federal Funds Rate and the interest rate applicable
thereto pursuant to Section 2.7 and (ii) in the case of such Bank, the Federal
Funds Rate.  If such Bank shall repay to the Lead Agent such corresponding
amount, such amount so repaid shall constitute such Bank's Loan included in such
Borrowing for purposes of this Agreement.

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 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 hereto, 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, 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 ten (10) Euro-Dollar Borrowings
outstanding at any one time pursuant to this Agreement.

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 sum of twenty-five (25) basis
points plus the Base Rate for such day.  Such interest shall be payable for each
Interest Period on the last day thereof.

          (b) Each Euro-Dollar Loan shall bear interest on the outstanding
principal amount thereof, for each day during the Interest Period applicable
thereto, at a rate per annum equal to the sum of the Applicable Margin plus the
Adjusted London Interbank Offered Rate for such day.

Such interest shall be payable for each Interest Period on the last day thereof
and, if such Interest Period is longer than three months, at intervals of three
months after the first day thereof.

          "Adjusted London Interbank Offered Rate" applicable to any Interest

Period means a rate per annum equal to the quotient obtained (rounded upward, if
necessary, to the next higher 1/100 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

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

          "London Interbank Offered Rate" applicable to any Interest Period
           -----------------------------
means the average (rounded upward, if necessary, to the next higher 1/16 of 1%)
of the respective rates per annum at which deposits in dollars are offered to
the Reference Bank in the London interbank market at approximately 11:00 a.m.
(London time) two Euro-Dollar Business Days before the first day of such
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.

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

quoted by the Bank making such Loan in accordance with Section 2.3. Such
interest shall be payable for each Interest Period on the last day thereof and,
if such Interest Period is longer than ninety days, at intervals of ninety days
after the first day thereof.

          (d   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%).

the Loans hereunder. 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.

quotations to the Lead Agent as contemplated by this Section. If the Reference
Bank does not furnish a timely quotation, the provisions of Section 8.1 shall

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

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 such lesser amount as shall be
required for the Borrower to remain in compliance with this Agreement, in the
event of such a sale, transfer or release.  Notwithstanding the foregoing, a
simultaneous like-kind exchange under Section 1031 of the Internal Revenue Code
will not be subject to the provisions of this Section 2.10(a), pro-

vided that the exchanged property has qualified as a New Acquisition and any
cash "boot" associated therewith shall be applied to prepayment of the Loans or
such lesser amount of such cash "boot" as shall be required for the Borrower to
remain in compliance with this Agreement. Sale of an Unencumbered Asset Pool
Property (or any Separate Parcel that originally formed a part of a Unencumbered
Asset Pool Property) in violation of this Section 2.10 shall constitute an Event
of Default.

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

          (c   in the event that the Unsecured Debt Ratio is not maintained
as of the last day of a calendar quarter, either (i) the Borrower will add a
Real Property Asset to the Unencumbered Asset Pool Properties in accordance with
this Agreement which, on a pro forma basis (i.e. the Unsecured Debt Ratio shall
                           ---------        ---

an Unencumbered Asset Pool Property for

the entire applicable period) would result in compliance with the Unsecured Debt
Ratio, or (ii) the Borrower shall prepay to the Lead Agent, for the account of
the Banks, an amount necessary to cause the Unsecured Debt Ratio to be in
compliance within ninety (90) days of the date on which the Unsecured Debt Ratio
failed to be maintained. Failure by the Borrower to comply with the Unsecured
Debt Ratio within ninety (90) days of the date of such non-compliance shall be
an Event of Default.

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

notice to the Lead Agent, prepay to the Lead Agent, for the account of the
Banks, any Base Rate Borrowing in whole at any time, or from time to time in

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 Borrowing.

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

Business Day), reimburse the Lead Agent for the benefit of the Fronting Bank for
the amount of any drawing under a Letter of Credit in whole or in part in any
amount.

excess thereof, by the delivery to the Lead Agent and the Banks of a notice of
cancellation upon at least three (3) Domestic Business Days' notice to Lead
Agent and the Banks, whereupon, all or such portion of the Commitments shall

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

                                       60


notice of cancellation which Loans, if any, are to be prepaid.

return of a Letter of Credit 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.

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

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

          (a   The Borrower shall make each payment of principal of, and
interest on, the Loans and of fees hereunder, not later than 3:00 p.m. (New York
City time) on the date when due, in Federal or other funds immediately available
in New York City, to the 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 3:00 p.m. (New
York City time), or, if received by the Lead Agent after 3:00 p.m. (New York
City time), on the immediately following Domestic Business Day. If the Lead
Agent shall fail to distribute to a Bank its ratable share of a payment on the
same day it is received or the immediately following Domestic Business Day, as
applicable in accordance with the immediately preceding sentence, the

                                       61


Lead Agent shall pay to such Bank the interest accrued on such payment at the
Federal Funds Rate, commencing on the day the Lead Agent should have made the
payment to such Bank and ending on the day prior to the date payment is actually
made. Whenever any payment of principal of, or interest on, the Base Rate Loans
or of fees shall be due on a day which is not a Domestic Business Day, the date
for payment thereof shall be extended to the next succeeding Domestic Business
Day. Whenever any payment of principal of, or interest on, the Euro-Dollar Loans
shall be due on a day which is not a Euro-Dollar Business Day, the date for
payment thereof shall be extended to the next succeeding Euro-Dollar Business
Day unless such Euro-Dollar Business Day falls in 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 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.

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

          (a   The Loans included in each Borrowing shall bear interest
initially at the type of rate specified by the Borrower in the applicable Notice
of Committed Borrowing. Thereafter, the Borrower may from time

                                       63


to time elect to change or continue the type of interest rate borne by each
Group of Loans (subject in each case to the provisions of Article VIII), as
follows:

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

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

Each such election shall be made by delivering a notice (a "Notice of Interest
                                                            ------------------
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 2:00 p.m. (New
York City time) at least one (1) Domestic Business Day before such continuation
is to be effective). A Notice of Interest Rate Election may, if it so specifies,
apply to only a portion of the aggregate principal amount of the relevant Group
of Loans; provided that (i) such portion is allocated ratably among the Loans
          --------
comprising such Group, (ii) the portion to which such notice applies, and the
remaining portion to which it does not apply, are each $1,000,000 or any larger
multiple of $1,000,000, (iii) there shall be no more than ten (10) Borrowings
comprised of Euro-Dollar Loans outstanding at any time under this Agreement,
(iv) no Loan may be continued as, or converted into, a Euro-Dollar Loan when any
Event of Default has occurred and

                                       64


is continuing, and (v) no Interest Period shall extend beyond the Maturity Date.

          (b   Each Notice of Interest Rate Election shall specify:

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

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

               (iii if the Loans comprising such Group are to be converted,
     the new type of Loans and, if such new Loans are Euro-Dollar Loans, the
     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 Euro-Dollar Loans, such Loans shall
be converted into Base Rate Loans on the last day of the then current Interest
Period applicable thereto.

                          -----------------
contained in this Agreement and the other Loan Documents, upon the receipt of a
notice in accordance with Section 2.2(b) requesting the issuance of a Letter of
Credit, the Fronting Bank shall issue a Letter of Credit or Letters of Credit in
such form as is reasonably acceptable to the Borrower in an amount or amounts
equal to the amount or amounts requested by the Borrower.

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

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

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

          (e   In the event of any request for a drawing under any Letter
of Credit by the beneficiary thereunder, the Fronting Bank shall endeavor to
notify the Borrower and the Lead Agent (and the Lead Agent shall endeavor to
notify each Bank thereof) on or before the date on which the Fronting Bank
intends to honor such drawing, and, except as provided in this subsection (e),
the Borrower shall reimburse the Fronting Bank, in immediately available funds,
on the same day on which such drawing is honored in an amount equal to the
amount of such drawing.  Notwithstanding anything contained herein to the
contrary, however, unless the Borrower shall have notified the Lead Agent and

Day immediately prior to the date of such drawing that the Borrower intends to
reimburse the Fronting Bank for the amount of such drawing with funds other than
the proceeds of the Loans, the Borrower shall be deemed to have timely given a
Notice of Committed Borrowing pursuant to

Section 2.2 to the Lead Agent, requesting a Borrowing of Base Rate Loans on the
date on which such drawing is honored and in an amount equal to the amount of
such drawing. Each Bank (other than the Fronting Bank) shall, in accordance with
Section 2.4(b), make available its share of such Borrowing to the Lead Agent,
the proceeds of which shall be applied directly by the Lead Agent to reimburse
the Fronting Bank for the amount of such draw. In the event that any such Bank
fails to make available to the Fronting Bank the amount of such Bank's
participation on the date of a drawing, the Fronting Bank shall be entitled to
recover such amount on demand from such Bank together with interest at the
Federal Funds Rate commencing on the date such drawing is honored.

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

          (g   If, after the date hereof, any change in any law or
regulation or in the interpretation thereof by any court or administrative or
governmental authority charged with the administration thereof shall either (i)

                                       67


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

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

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

                                       69


Letters of Credit issued by it or the related certificates, if taken or omitted
in good faith, shall not put the Fronting Bank under any resulting liability to
the Borrower.

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

person" (as such term is defined in Section 4975(e)(2) of the Code) with respect

     the Unencumbered Asset Pool Properties, or with respect to any generation,
     treatment, storage, recycling, transportation, Release or disposal of any

with all laws, rules, regulations, orders, judgments, writs and decrees,

to one or more persons, or property damage, as well as workers' compensation
insurance, in each case with respect to the Real Property Assets with insurers

                                                                ----

Borrower believes that the year 2000 problem will not result in a Material
Adverse Effect.

          Section VI.2.  Rights and Remedies.  (a)  Upon the occurrence of any
                         -------------------
Event of Default described in Sections 6.1(f) or (g), the unpaid principal
amount of, and any and all accrued interest on, the Loans and any and all
accrued fees and other Obligations hereunder shall automatically become
immediately due and payable, with all additional interest from time to time
accrued thereon and without presentation, demand, or protest or other
requirements of any kind (including, without limitation, valuation and
appraisement, diligence, presentment, notice of intent to demand or accelerate
and notice of acceleration), all of which are hereby expressly waived by the
Borrower; and upon the occurrence and during the continuance of any other Event
of Default, the Lead Agent may 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.

                                      107


          (b) Notwithstanding the foregoing, upon the occurrence and during the
continuance of any Event of Default other than any Event of Default described in
Sections 6.1(f) or (g), the Lead Agent shall not exercise any of its rights and
remedies hereunder nor declare the unpaid principal amount of and any and all
accrued and unpaid interest on the Loans and any and all accrued fees and other
Obligations hereunder to be immediately due and payable, until such time as the
Lead Agent shall have delivered a notice to the Banks specifying the Event of
Default which has occurred and whether Lead Agent recommends the acceleration of
the Obligations due hereunder or the exercise of other remedies hereunder.  The
Banks shall notify the Lead Agent if they approve or disapprove of the
acceleration of the Obligations due hereunder or the exercise of such other
remedy recommended by Lead Agent within five (5) Domestic Business Days after
receipt of such notice.  If any Bank shall not respond within such five (5)
Domestic Business Day period, then such Bank shall be deemed to have accepted
Lead Agent's recommendation for acceleration of the Obligations due hereunder or
the exercise of such other remedy.  If the Required Banks shall approve the
acceleration of the Obligations due hereunder or the exercise of such other
remedy, then Lead Agent shall declare the unpaid principal amount of and any and
all accrued and unpaid interest on the Loans and any and all accrued fees and
other Obligations hereunder to be immediately due and payable or exercise such
other remedy approved by the Required Banks.  If the Required Banks shall
neither approve nor disapprove the acceleration of the Obligations due hereunder
or such other remedy recommended by Lead Agent, then Lead Agent may accelerate
the Obligations due hereunder or exercise any of its rights and remedies
hereunder in its sole discretion.  If the Required Banks shall disapprove the
acceleration of the Obligations due hereunder or the exercise of such other
remedy recommended by Lead Agent, but approve of another remedy, then to the
extent permitted hereunder,

                                      108


Lead Agent shall exercise such remedy. In the event the Lead Agent exercises any
remedy provided in any of the Loan Documents, the Lead Agent shall act as a
collateral agent for the Banks.

          Section VI.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.

          Section VI.4.  Actions in Respect of Letters of Credit.  (a)  If, at
                         ---------------------------------------
any time and from time to time, any Letter of Credit shall have been issued
hereunder and an Event of Default shall have occurred and be continuing, then,
upon the occurrence and during the continuation thereof, the Lead Agent may,
whether in addition to the taking by the Lead Agent of any of the actions
described in this Article or otherwise, make a demand upon the Borrower to, and
forthwith upon such demand (but in any event within ten (10) days after such
demand) the Borrower shall, pay to the Lead Agent, on behalf of the Banks, in
same day funds at the Lead Agent's office designated in such demand, for deposit
in a special cash collateral account (the "Letter of Credit Collateral Account")
                                           -----------------------------------
to be maintained in the name of the Lead Agent (on behalf of the Banks) and
under its sole dominion and control at such place as shall be designated by the
Lead Agent, an amount equal to the amount of the Letter of Credit Usage under
the Letters of Credit.  Interest shall accrue on the Letter of Credit Collateral
Account at a rate equal to the rate on overnight funds.

          (b) The Borrower hereby pledges, assigns and grants to the Lead Agent,
as administrative agent for its benefit and the ratable benefit of the Banks a
lien

                                      109


on and a security interest in, the following collateral (the "Letter of
                                                              ---------
Credit Collateral"):
- -----------------

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

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

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

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

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

          (c) The Borrower hereby authorizes the Lead Agent for the ratable
benefit of the Banks to apply, from time to time after funds are deposited in
the Letter of Credit Collateral Account, funds then held in the Letter of Credit
Collateral Account to the payment of any amounts, in such order as the Lead
Agent may elect, as shall have become due and payable by the Borrower to the
Banks in respect of the Letters of Credit.

                                      110


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

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

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

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

              (ii) The Lead Agent may also exercise, in its sole discretion,
     in respect of the Letter of Credit Collateral Account, in addition to the
     other rights and remedies provided herein or otherwise available to it, all
     the rights and remedies of a

                                      111


     secured party upon default under the Uniform Commercial Code in effect in
     the State of New York at that time.

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

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

                                 THE LEAD AGENT

          Section VII.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.

                                      112


          Section VII.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 VII.3.  Action by Lead Agent.  The obligations of the Lead
                          --------------------

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 VII.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 VII.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

                                      113


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

          Section VII.6.  Indemnification.  Each Bank shall, ratably in
                          ---------------

result from such indemnitees' gross negligence or willful misconduct) that such
indemnitees may suffer or incur as a result of, or in connection with, the Lead
Agent's capacity as Lead Agent in connection with this Agreement, the other Loan
Documents or any action taken or omitted by such indemnitees in accordance with
this Agreement.

          Section VII.7.  Credit Decision.  Each Bank acknowledges that it has,
                          ---------------
independently and without reliance upon the Lead Agent or any other Bank, and

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.

                                      114


          Section VII.8.  Successor Lead Agent.  The Lead Agent may resign at
                          --------------------
any time by giving notice thereof to the Banks and the Borrower.  In addition,
if the Lead Agent at any time shall have been finally determined to have
committed gross negligence or willful misconduct in connection with its
performance of its duties as Lead Agent hereunder, then, upon notice from the
Required Banks, the Lead Agent shall resign. Upon any such resignation, 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 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 of America 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 hereunder first accruing or arising after the effective
date of such retirement.  After any retiring Lead Agent's resignation 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.

          If, at any time during the Term, the Lead Agent shall no longer have
any Commitment under this Agreement, the Lead Agent shall give notice of its
offer to resign to the Banks and the Borrower.  Upon any such offer of
resignation, the Required Banks shall have the

                                      115


right to appoint a successor Lead Agent or to retain the Lead Agent with the
consent of the Borrower, provided that no Event of Default shall be outstanding.

          Section VII.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 VII.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; and Lead Agent shall
deliver to each Bank a copy of any notice sent to the Lead Agent by the Borrower
in connection with any Default or Event of Default hereunder.

                            CHANGE IN CIRCUMSTANCES

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

          (a) the 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 affected
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 for such Interest Period, the Lead
Agent shall

                                      116


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 to continue or convert outstanding Loans as or into Euro-Dollar Loans,
as the case may be, shall be suspended, and each outstanding Euro-Dollar Loan
shall be converted into a Base Rate Loan on the last day of the then current
Interest Period applicable thereto. Unless the Borrower notifies the Lead Agent
at least two Domestic Business Days before the date of any Euro-Dollar Borrowing
or Money Market LIBOR Borrowing for which a Notice of Borrowing has previously
been given that it elects not to borrow on such date, (i) if such Borrowing is a
Committed Borrowing, such Borrowing shall instead be made as a Base Rate
Borrowing, and (ii) if such Borrowing is a Money Market LIBOR Borrowing, the
Money Market LIBOR Loans comprising such Borrowing shall bear interest for each
day from and including the first day to but excluding the last day of the
Interest Period applicable thereto at the Base Rate for such day.

          Section VIII.2.  Illegality.  If, after the date of this Agreement,
                           ----------
the adoption of any applicable law, rule or regulation, or any change in any
existing applicable law, rule or regulation, or any change in the interpretation
or administration thereof by any governmental authority, central bank or
comparable agency charged with the interpretation or administration thereof, or
compliance by any Bank (or its Euro-Dollar Lending Office) with any request or
directive (whether or not having the force of law) of any such authority,
central bank or comparable agency shall make it unlawful or impossible for any
Bank (or its Euro-Dollar Lending Office) to make, maintain or fund its Euro-
Dollar Loans or Money Market Loans or to participate in any Letter of Credit
issued by the Fronting Bank, or, with respect to the Fronting Bank, to issue any
Letter of Credit, and

                                      117


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 or convert
Euro-Dollar Loans or Money Market Loans, or to participate in any Letter of
Credit issued by the Fronting Bank or, with respect to the Fronting Bank, to
issue any Letter of Credit, shall be suspended. Before giving any notice to the
Lead Agent pursuant to this Section, such Bank shall designate a different Euro-
Dollar Lending Office if such designation will avoid the need for giving such
notice and will not, in the judgment of such Bank, be otherwise disadvantageous
to such Bank. If such Bank shall determine that it may not lawfully continue to
maintain and fund any of its outstanding Euro-Dollar Loans or Money Market Loans
(as the case may be) to maturity and shall so specify in such notice, the
Borrower shall immediately prepay in full the then outstanding principal amount
of each such Euro-Dollar Loan or Money Market Loan, together with accrued
interest thereon. Concurrently with prepaying each such Euro-Dollar Loan, the
Borrower shall borrow a Base Rate Loan in an equal principal amount from such
Bank (on which interest and principal shall be payable contemporaneously with
the related Euro-Dollar Loans or Money Market Loans of the other Banks), and
such Bank shall make such a Base Rate Loan.

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

          (a) If, after (x) the date hereof, in the case of any Committed Loan
or any obligation to make Committed Loans or (y) the date of the related Money
Market Quote, in the case of any Money Market Loan, the adoption of any
applicable law, rule or regulation, or any change in any applicable law, rule or
regulation, or

                                      118


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

          (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

                                      119


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

          (c) Each Bank will promptly notify the Borrower and the 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 conclusive in the absence of
manifest error.  In determining such amount, such Bank may use any reasonable
averaging and attribution methods.

                                -----

                                      120


          (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 jurisdiction of
such Bank's Applicable Lending Office, the jurisdiction of the domicile of its
Loans either established by the Bank pursuant to Section 9.12 or determined by
the applicable taxing authorities)(all such non-excluded taxes, duties, levies,
imposts, deductions, charges, withholdings and liabilities being hereinafter
referred to as "Taxes").  If the Borrower shall be required by law to deduct any
                -----
Taxes from or in respect of any sum payable hereunder or under any Note or
Letter of Credit or participation therein to any Bank or the 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, the Fronting 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.

                                      121


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

          (c) The Borrower agrees to indemnify each Bank, the Fronting Bank and
the 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, the Fronting 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 15 days from the date
such Bank, the Fronting 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 do so), shall provide the
Borrower with Internal Revenue Service form 1001 or 4224, as appropriate, or any
successor form prescribed by the Internal Revenue Service, certifying that such
Bank is entitled to benefits under an income tax treaty to which the United
States is a party which reduces the rate of withholding tax on payments of
interest or certifying that the income receiv-

                                      122


able 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 de-

                                      123


liver a form required hereunder, the Borrower shall take such steps as such Bank
shall reasonably request to assist such Bank to recover such Taxes.

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

                           ----------------------------------------------------
Loans.  If (i) the obligation of any Bank to make, or convert outstanding Loans
- -----
to, Euro-Dollar Loans has been suspended pursuant to Sections 8.1 or 8.2 or (ii)
any Bank has demanded compensation under Section 8.3 or 8.4 with respect to its
Euro-Dollar Loans and the Borrower shall, by at least five 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.

          Section IX.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

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 IX.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
counsel for the Lead Agent, and travel, site visits, third party reports
(including Appraisals), mortgage recording taxes, environmental and engineering
expenses), in connection with the preparation and administration of this
Agreement, the Loan Documents and the documents and instruments referred to
therein, the syndication of the Loans, any waiver or consent hereunder or any
amendment or modification hereof or any Default or alleged Default hereunder and
(ii) if an Event of Default occurs, all out-of-pocket expenses incurred by the
Lead Agent and each Bank, including, without limitation, reasonable fees and
disbursements of counsel for the Lead Agent, in connection with the enforcement
of the Loan Documents and the instruments referred to therein and such Event of
Default and collection, bankruptcy, insolvency and other enforcement proceedings
resulting therefrom.

          (b) The Borrower agrees to indemnify the Lead Agent and each Bank,
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 liabil-

                                      126


ities, 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 in each case, as to any Indemnitee, any such losses, liabilities,
claims, damages, expenses, obligations, penalties, actions, judgments, suits,
costs or disbursements incurred solely by reason of (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

                                      127


any bank regulatory agency or by any equity holder of such Indemnitee). The
Borrower's obligations under this Section shall survive the termination of this
Agreement and the payment of the Obligations.

          (c) The Borrower shall pay, and hold the Lead Agent and each of the
Banks harmless from and against, any and all present and future U.S. stamp,
recording, transfer and other similar foreclosure related taxes with respect to
the foregoing matters and hold the 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 IX.4.  Sharing of Set-Offs.  In addition to any rights now or
                         -------------------
hereafter granted under applicable law or otherwise, and not by way of
limitation of any such rights, upon the occurrence and during the continuance of
any Event of Default, each Bank is hereby authorized at any time or from time to
time, without presentment, demand, protest or other notice of any kind to the
Borrower or to any other Person, any such notice being hereby expressly waived,
to set off and to appropriate and apply any and all deposits (general or
special, time or demand, provisional or final), other than deposits held for the
benefit of third parties, and any other indebtedness at any time held or owing
by such Bank (including, without limitation, by branches and agencies of such
Bank wherever located) to or for the credit or the account of the Borrower
against and on account of the Obligations of the Borrower then due and payable
to such Bank under this Agreement or under any of the other Loan Documents,
including, without limitation, all interests in Obligations purchased by such
Bank.  Each Bank agrees that if it shall, by exercising any right of set-off or
counterclaim or otherwise, receive payment of a proportion of the aggregate
amount of principal and interest due with respect to any Note held

                                      128


by it or Letter of Credit participated in by it, or, in the case of the Fronting
Bank, Letter of Credit issued by it, which is greater than the proportion
received by any other Bank or Letter of Credit issued or participated in by such
other Bank, in respect of the aggregate amount of principal and interest due
with respect to any Note held by such other Bank, the Bank receiving such
proportionately greater payment shall purchase such participations in the Notes
held by the other Banks or Letter of Credit issued or participated in by such
other Bank, and such other adjustments shall be made, as may be required so that
all such payments of principal and interest with respect to the Notes held by
the Banks or Letter of Credit issued or participated in by such other Banks
shall be shared by the Banks pro rata; provided that nothing in this Section
                                       --------
shall impair 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 or the Letters of Credit. The Borrower agrees, to the fullest extent that
it may effectively do so under applicable law, that any holder of a
participation in a Note, whether or not acquired pursuant to the foregoing
arrangements, may exercise rights of set-off or counterclaim and other rights
with respect to such participation as fully as if such holder of a participation
were a direct creditor of the Borrower in the amount of such participation.

          Section IX.5.  Amendments and Waivers.  Any provision of this
                         ----------------------
Agreement (including any of the financial covenants given by the Borrower
pursuant to Section 5.8), the Notes, the Letters of Credit or other Loan
Documents may be amended or waived if, but only if, such amendment or waiver is
in writing and is signed by the Borrower and the Required Banks (and, if the
rights or duties of the Lead Agent are affected thereby, by the Lead Agent);
provided that no such amendment or waiver
- --------

                                      129


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, (ii) reduce the principal of or
rate of interest on any Loan or any fees specified herein, (iii) postpone the
date fixed for any payment of principal of or interest on any Loan or any fees
hereunder or for any reduction or termination of any Commitment, (iv) release
the Guaranty or otherwise release any other collateral, (v) subordinate the
Loans to any other Debt, or (vi) change the percentage of the Commitments or of
the aggregate unpaid principal amount of the Notes, or the number of Banks,
which shall be required for the Banks or any of them to take any action under
this Section or any other provision of this Agreement. Notwithstanding the
foregoing, no amendment, waiver or consent shall, unless in writing and signed
by the Designating Lender on behalf of its Designated Lender affected thereby,
(a) subject such Designated Lender to any additional obligations, (b) reduce the
principal of, interest on, or other amounts due with respect to, the Designated
Lender Note made payable to such Designated Lender, or (c) postpone any date
fixed for any payment of principal of, or interest on, or other amounts due with
respect to the Designated Lender Note made payable to the Designated Lender.

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

          (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")
                      -----------

                                      130


participating interests in its Commitment or any or all of its Loans. In the
event of any such grant by a Bank of a participating interest to a Participant,
whether or not upon notice to the Borrower and the 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, of its
                       --------
rights and obligations under this Agreement, the Notes and the other Loan
Documents, and such Assignee shall assume such rights and obligations, pursuant
to an Assignment and Assumption Agreement in substantially the form of Exhibit D
                                                                       ---------
attached hereto executed by such Assignee and such transferor Bank, with (and
subject to) the subscribed consent of the Lead Agent, which consent shall not be
unreasonably withheld, and, provided no Event of

                                      131


Default shall have occurred and be continuing, the Borrower, which consent shall
not be unreasonably withheld or delayed. Upon execution and delivery of such
instrument and payment by such Assignee to such transferor Bank of an amount
equal to the purchase price agreed between such transferor Bank and such
Assignee, such Assignee shall be a Bank party to this Agreement and shall have
all the rights and obligations of a Bank with a Commitment as set forth in such
instrument of assumption, and the transferor Bank shall be released from its
obligations hereunder to a corresponding extent, and no further consent or
action by any party shall be required. Upon the consummation of any assignment
pursuant to this subsection (c), the transferor Bank, the 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 (except
for an assignment by a Bank to its Affiliate), 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 of America 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.  The parties to each such designation shall
execute and deliver to the Lead Agent for its acceptance a Designation
Agreement.  Upon such receipt of an appropriately completed Designation
Agreement executed by a Designating Lender and a designee representing that it
is a Designated Lender, the Lead

                                      132


Agent will accept such Designation Agreement and will give prompt notice thereof
to the Borrower, whereupon, (i) the Borrower shall execute and deliver to the
Designating Bank a Designated Lender Note payable to the order of the Designated
Lender, (ii) from and after the effective date specified in the Designation
Agreement, the Designated Lender shall become a party to this Agreement with a
right (subject to the provisions of Section 2.3(b)) to make Money Market Loans
on behalf of its Designating Lender pursuant to Section 2.3 after the Borrower
has accepted a Money Market Loan (or portion thereof) of the Designating Lender,
and (iii) the Designated Lender shall not be required to make payments with
respect to any obligations in this Agreement except to the extent of excess cash
flow of such Designated Lender which is not otherwise required to repay
obligations of such Designated Lender which are then due and payable; provided,
however, that regardless of such designation and assumption by the Designated
Lender, the Designating Lender shall be and remain obligated to the Borrower and
the Banks for each and every of the obligations of the Designating Lender and
its related Designated Lender with respect to this Agreement, including, without
limitation, any indemnification obligations under Section 7.6 hereof and any
sums otherwise payable to the Borrower by the Designated Lender. Each
Designating Lender shall serve as the administrative agent of the Designated
Lender and shall on behalf of, and to the exclusion of, the Designated Lender:
(i) receive any and all payments made for the benefit of the Designated Lender
and (ii) give and receive all communications and notices and take all actions
hereunder, including, without limitation, votes, approvals, waivers, consents
and amendments under or relating to this Agreement and the other Loan Documents.
Any such notice, communication, vote, approval, waiver, consent or amendment
shall be signed by the Designating Lender as administrative agent for the
Designated Lender and shall not be signed by the Designated Lender on its own
behalf and shall be binding

                                      133


upon the Designated Lender to the same extent as if signed by the Designated
Lender on its own behalf. The Borrower, the Lead Agent, and the Banks may rely
thereon without any requirement that the Designated Lender sign or acknowledge
the same. No Designated Lender may assign or transfer all or any portion of its
interest hereunder or under any other Loan Document, other than assignments to
the Designating Lender which originally designated such Designated Lender or
otherwise in accordance with the provisions of Section 9.6(b) and (c).

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

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

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

          (a) THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE CONSTRUED IN

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 of America for the Southern District of New York, and, by
execution and delivery of this Agreement, the Borrower hereby accepts for itself

                          Dated _____________, 199___


         Reference is made to that certain Second Amended and Restated Revolving

Agreement are used herein with the same meaning.

         [NAME OF DESIGNOR] (the "Designor"), [NAME OF DESIGNEE] (the
"Designee") and the Lead Agent agree as follows:

         1.   The Designor hereby designates the Designee, and the Designee
hereby accepts such designation, to have a right to make Money Market Loans
pursuant to Article III of the Credit Agreement.  Any assignment by Designor to
Designee of its rights to make a Money Market Loan pursuant to such Article III
shall be effective at the time of the funding of such Money Market Loan and not
before such time.

         2.   Except as set forth in Section 7 below, the Designor makes no
representation or warranty and assumes no responsibility pursuant to this
Designation Agreement with respect to (a) any statements, warranties or
representations made in or in connection with any Loan Document or the
execution, legality, validity, enforceability, genuineness, sufficiency or value
of any Loan Document or any other instrument and document furnished pursuant
thereto and (b) the financial condition of the Borrower or the performance or
observance by the Borrower of any of its obli-

                                      H-1


gations under any Loan Document or any other instrument or document furnished
pursuant thereto.

     3.   The Designee (a) confirms that it has received a copy of each Loan
Document, together with copies of the financial statements referred to in
Articles IV and V of the Credit Agreement and such other documents and
information as it has deemed appropriate to make its own credit analysis and
decision to enter into this Designation Agreement; (b) agrees that it will
independently and without reliance upon the Lead Agent, the Designor or any
other Bank and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under any Loan Document; (c) confirms that it is a Designated
Lender; (d) appoints and authorizes the Lead Agent to take such action as agent
on its behalf and to exercise such powers and discretion under any Loan Document
as are delegated to the Lead Agent by the terms thereof, together with such
powers and discretion as are reasonably incidental thereto; and (e) agrees to be
bound by each and every provision of each Loan Document and further agrees that
it will perform in accordance with their terms all of the obligations which by
the terms of any Loan Document are required to be performed by it as a Bank.

     4.   The Designee hereby appoints Designor as Designee's agent and attorney
in fact, and grants to Designor an irrevocable power of attorney, to receive
payments made for the benefit of Designee under the Credit Agreement, to deliver
and receive all communications and notices under the Credit Agreement and other
Loan Documents and to exercise on Designee's behalf all rights to vote and to
grant and make approvals, waivers, consents of amendments to or under the Credit
Agreement or other Loan Documents.  Any document executed by the Designor on the
Designee's behalf in connection with the Credit Agreement or other Loan
Documents shall be binding on the Designee.  The Borrower, the Lead Agent and
each of the Banks may rely on and are beneficiaries of the preceding provisions.

     5.   Following the execution of this Designation Agreement by the Designor
and its Designee, it will be delivered to the Lead Agent for acceptance and
recording by the Lead Agent.  The effective date for this Designation Agreement
(the "Effective Date") shall be the date of acceptance hereof by the Lead Agent,
unless otherwise specified on the signature page thereto.

                                      H-2


     6.  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.

     7.   The Designor unconditionally agrees to pay or reimburse the Designee
and save the Designee harmless against all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind or nature whatsoever which may be imposed or asserted by any of the
parties to the Loan Documents against the Designee, in its capacity as such, in
any way relating to or arising out of this Agreement or any other Loan Documents
or any action taken or omitted by the Designee hereunder or thereunder, provided
                                                                        --------
that the Designor shall not be liable for any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements if the same results from the Designee's gross
negligence or willful misconduct.

     8.   Upon such acceptance and recording by the Lead Agent, as of the
Effective Date, the Designee shall be a party to the Credit Agreement with a
right (subject to the provisions of Section 2.3(b)) to make Money Market Loans
as a Bank pursuant to Section 2.3 of the Credit Agreement and the rights and
obligations of a Bank related thereto; provided, however, that the Designee
                                       -----------------
shall not be required to make payments with respect to such obligations except
to the extent of excess cash flow of such Designee which is not otherwise
required to repay obligations of such Designated Lender which are then due and
payable.  Notwithstanding the foregoing, the Designor, as administrative agent
for the Designee, shall be and remain obligated to the Borrower, the Co-Agents
and the Banks for each and every of the obligations of the Designee and its
Designor with respect to the Credit Agreement, including, without limitation,
any indemnification obligations under Section 7.6 of the Credit Agreement and
any sums otherwise payable to the Borrower by the Designee.

     9.   This Designation Agreement shall be governed by, and construed in
accordance with, the laws of the State of New York.

                                      H-3


     10.  This Designation Agreement may be executed in any number of
counterparts and by different parties hereto in separate counterparts, each of
which when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.  Delivery of an executed
counterpart of a signature page to this Designation Agreement by facsimile
transmission shall be effective as delivery of a manually executed counterpart
of this Designation Agreement.

                                      H-4


     IN WITNESS WHEREOF, the Designor and the Designee, intending to be legally
bound, have caused this Designation Agreement to be executed by their officers
thereunto duly authorized as of the date first above written.
