                                   ARTICLE II

                                   THE CREDIT

         2.1. COMMITMENT. From and including the date of this Agreement and
prior to the Revolving Credit Termination Date, each Lender severally agrees,
subject to the terms and conditions set forth in this Agreement, to make Loans
to the Borrower from time to time prior to the Revolving Credit Termination
Date, provided THAT the making of any such Loan will not cause the total of the
outstanding principal balance of all Loans to exceed the Aggregate Commitment.
Each Lender shall fund its Percentage of each Advance and no Lender will be
required to fund any amount, which when aggregated with such Lender's Percentage
of all other Advances then outstanding would exceed such Lender's Commitment.
Subject to the terms of this Agreement, the Borrower may borrow, repay and
reborrow at any time prior to the Revolving Credit Termination Date. The
Commitments of each Lender to lend hereunder shall expire on the Revolving
Credit Termination Date.

         2.2. FINAL PRINCIPAL PAYMENT. Any outstanding Advances and all other
unpaid Obligations shall be paid in full by the Borrower on the Facility
Termination Date.

         2.3. LOANS. Each Advance hereunder shall consist of Loans made from the
several Lenders ratably in proportion to the ratio that their respective
Commitments bear to the Aggregate Commitment. The Advances may be CBR Advances
or LIBOR Advances, or a combination thereof, selected by the Borrower in
accordance with SECTIONS 2.10 and 2.11.

         2.4. APPLICABLE MARGINS. The CBR Applicable Margin and the LIBOR
Applicable Margin to be used in calculating the interest rate applicable to
different Types of Advances shall vary from time to time in accordance with the
long-term unsecured debt ratings from Moody's, Duff & Phelps and S&P of the
General Partner and the Borrower. In the event the General Partner and the
Borrower have different ratings, the rating of the higher rated entity shall be
used. In the event the rating agencies are split on the rating for the higher
rated entity, the second highest rating for such entity shall be deemed to be
the applicable rating (e.g., if the higher rated entity's Moody's debt rating is
Baa1, its S&P debt rating is BBB and its Duff and Phelps' rating is BBB, then
the Applicable Margins shall be computed based on the S&P rating), and the
Applicable Margins shall be adjusted effective on the next Business Day
following any change in the higher rated entity's Moody's debt rating, S&P's
debt rating and/or Duff & Phelps'


                                      -15-
<PAGE>

debt rating, as the case may be. The applicable debt ratings and the Applicable
Margins are set forth in the table attached as EXHIBIT A. In the event that S&P,
Duff & Phelps or Moody's or any two of them shall discontinue their ratings of
the REIT industry, the General Partner or the Borrower, a mutually agreeable
substitute rating agency (or two mutually agreeable substitute agencies if two
of the existing rating agencies discontinue such ratings) shall be selected by
the Required Lenders and the Borrower. If the Required Lenders and the Borrower
cannot agree on a substitute rating agency or substitute rating agencies within
thirty (30) days of such discontinuance, or if S&P, Duff & Phelps, and Moody's
shall discontinue their ratings of the REIT industry, the Borrower, or the
General Partner, the Applicable Margin to be used for the calculation of
interest on Advances hereunder shall be the highest Applicable Margin for each
Type.

         If a rating agency downgrade or discontinuance results in an increase
in the CBR Applicable Margin or the LIBOR Applicable Margin and if such increase
is reversed and the affected Applicable Margin is restored within ninety (90)
days thereafter, at the Borrower's request, the Borrower shall receive a credit
against interest next due the Lenders equal to interest accrued from time to
time during such period of downgrade or discontinuance and actually paid by the
Borrower on the Advances at the differential between such Applicable Margins.

         2.5. FACILITY FEE. The Borrower agrees to pay to the Administrative
Agent for the account of each Lender a facility fee (the "FACILITY FEE")
calculated at a per annum percentage ("FACILITY FEE RATE") of the total
Aggregate Commitment. The Facility Fee Rate shall vary from time to time based
on the Borrower's or General Partner's long term unsecured debt rating as set
forth in the table attached hereto as EXHIBIT A, payable quarterly in arrears on
the last day of each calendar quarter hereafter beginning September 30, 1999 and
on the Facility Termination Date.

         2.6. UPFRONT FEE. The Borrower will pay to Administrative Agent for the
benefit of the Lenders on or before the date hereof the fees specified in that
certain Fee Letter dated June 7, 1999. The Administrative Agent shall distribute
such fees to the Lenders in accordance with a separate agreement between the
Administrative Agent and the Lenders.

         2.7. CONVERSION AND EXTENSION FEES. If Borrower exercises its option
pursuant to a Term Loan Request under SECTION 2.25 of this Agreement to convert
the aggregate outstanding Loans to a term loan, Borrower shall pay each Lender a
fee equal to 0.175% of the aggregate of such Lender's outstanding Loans on the
initial Revolving Credit Termination Date. If the Facility is extended pursuant
to an Extension Request under SECTION 2.25 of this Agreement, Borrower shall pay
each Continuing Lender a fee equal to 0.175% of such Continuing Lender's
Commitment immediately after the extension and reallocation of all of the
Commitments pursuant to SECTION 2.25.

         2.8. MINIMUM AMOUNT OF EACH ADVANCE. Each LIBOR Advance shall be in the
minimum amount of $2,000,000 (and in multiples of $1,000,000 if in excess
thereof), and each CBR Advance shall be in the minimum amount of $1,000,000 (and
in multiples of $500,000 if in excess thereof), provided, however, that any CBR
Advance may be in the amount of the unused Aggregate Commitment.


                                      -16-
<PAGE>

         2.9. OPTIONAL PRINCIPAL PAYMENTS. The Borrower may from time to time
pay, without penalty or premium, all or any part of outstanding CBR Advances
upon two Business Days' prior notice to the Administrative Agent. The Borrower
may from time to time pay a LIBOR Advance, provided a LIBOR Advance may not be
paid prior to the last day of the applicable LIBOR Interest Period unless
accompanied by any amount due pursuant to Section 4.4.

         2.10. METHOD OF SELECTING TYPES AND INTEREST PERIODS FOR NEW ADVANCES.
The Borrower shall select the Type of Advance and, in the case of each LIBOR
Advance, the LIBOR Interest Period applicable to each Advance from time to time.
The Borrower shall give the Administrative Agent irrevocable notice (a
"Borrowing Notice") (i) not later than 10:00 a.m. Chicago time, at least one (1)
Business Day before the Borrowing Date of each CBR Advance and (ii) not later
than 10:00 a.m. Chicago time, at least three (3) Business Days before the
Borrowing Date for each LIBOR Advance, specifying:

               (a)    the Borrowing Date, which shall be a Business Day, of such
                      Advance,

               (b)    the aggregate amount of such Advance,

               (c)    the Type of Advance selected, and

               (d)    in the case of each LIBOR Advance, the LIBOR Interest
                      Period applicable thereto.

         Not later than noon (Chicago time) on each Borrowing Date, each Lender
shall make available its Loan or Loans, in funds immediately available in
Chicago to the Administrative Agent at its address specified pursuant to ARTICLE
XIV. The Lenders shall not be obligated to match fund their LIBOR Advances. The
Administrative Agent will make the funds so received from the Lenders available
to the Borrower at the Administrative Agent's aforesaid address.

         No LIBOR Interest Period may end after the Facility Termination Date
and, unless all of the Lenders otherwise agree in writing, in no event may there
be more than five (5) different LIBOR Interest Periods for LIBOR Advances
outstanding at any one time.

         2.11. CONVERSION AND CONTINUATION OF OUTSTANDING ADVANCES. CBR Advances
shall continue as CBR Advances unless and until such CBR Advances are converted
into LIBOR Advances. Each LIBOR Advance shall continue as a LIBOR Advance until
the end of the then applicable LIBOR Interest Period therefor, at which time
such LIBOR Advance shall be automatically converted into an CBR Advance unless
the Borrower shall have given the Administrative Agent a Conversion/Continuation
Notice requesting that, at the end of such LIBOR Interest Period, such LIBOR
Advance continue as a LIBOR Advance for the same or another LIBOR Interest
Period. Subject to the terms of SECTION 2.8, the Borrower may elect from time to
time to convert all or any part of an Advance of any Type into any other Type of
Advance; provided that any conversion of any LIBOR Advance shall be made on, and
only on, the last day of the LIBOR Interest Period applicable thereto. The
Borrower shall give the Administrative Agent irrevocable notice (a
"Conversion/Continuation Notice") of each conversion of an Advance or
continuation of a LIBOR Advance not later than 10:00 a.m. (Chicago time) at
least one Business Day, in the case of a conversion into an CBR Advance, or


                                      -17-
<PAGE>

three Business Days, in the case of a conversion into or continuation of a
LIBOR Advance, prior to the date of the requested conversion or continuation,
specifying:

               (i)    the requested date which shall be a Business Day, of such
                      conversion or continuation;

               (ii)   the aggregate amount and Type of the Advance which is to
                      be converted or continued; and

               (iii)  the amount and Type(s) of Advance(s) into which such
                      Advance is to be converted or continued and, in the case
                      of a conversion into or continuation of a LIBOR Advance,
                      the duration of the LIBOR Interest Period applicable
                      thereto.

         2.12. CHANGES IN INTEREST RATE, ETC. Each CBR Advance shall bear
interest on the outstanding principal amount thereof, for each day from and
including the date such Advance is made or is converted from a LIBOR Advance
into a CBR Advance pursuant to SECTION 2.11 to but excluding the date it becomes
due or is converted into a LIBOR Advance pursuant to SECTION 2.11 hereof, at a
rate per annum equal to the CBR Rate for such day. Changes in the rate of
interest on that portion of any Advance maintained as a CBR Advance will take
effect simultaneously with each change in the Corporate Base Rate. Each LIBOR
Advance shall bear interest from and including the first day of the LIBOR
Interest Period applicable thereto to (but not including) the last day of such
LIBOR Interest Period at the interest rate determined as applicable to such
LIBOR Advance.

         2.13. RATES APPLICABLE AFTER DEFAULT. Notwithstanding anything to the
contrary contained in SECTION 2.10 or 2.11, during the continuance of a Default
or Unmatured Default the Required Lenders may, at their option, by notice to the
Borrower (which notice may be revoked at the option of the Required Lenders
notwithstanding any provision of SECTION 9.2 requiring unanimous consent of the
Lenders to changes in interest rates), declare that no Advance may be made as,
converted into or continued beyond its current term as a LIBOR Advance. During
the continuance of a Default the Required Lenders may, at their option, by
notice to the Borrower (which notice may be revoked at the option of the
Required Lenders notwithstanding any provision of SECTION 9.2 requiring
unanimous consent of the Lenders to changes in interest rates), declare that (i)
each LIBOR Advance shall bear interest for the remainder of the applicable LIBOR
Interest Period at the rate otherwise applicable to such LIBOR Interest Period
plus 2% per annum and (ii) each CBR Advance shall bear interest at a rate per
annum equal to the CBR Rate otherwise applicable to the CBR Advance plus 2% per
annum; provided that such rates shall become applicable automatically without
notice to the Borrower if a Default occurs under SECTION 8.7 or SECTION 8.8.

                                      -18-
<PAGE>

Agent at the Administrative Agent's address specified pursuant to ARTICLE XIV,
or at any other Lending Installation of the Administrative Agent specified in
writing by the Administrative Agent to the Borrower, by noon (local time) on the
date when due and shall be applied by the Administrative Agent among the Lenders
in accordance with the class or type of Obligation being paid. Each payment
delivered to the Administrative Agent for the account of any Lender shall be
delivered by the Administrative Agent to such Lender in the same type of funds
that the Administrative Agent received at its address specified pursuant to
ARTICLE XIV or at any Lending Installation specified in a notice received by the
Administrative Agent from such Lender promptly, which is expected to be by the
close of business on the same Business Day received by Administrative Agent if
received by noon (local time) but shall in any event not be later than the next
Business Day, PROVIDED that the Administrative Agent shall pay to such Lenders
interest thereon, at the lesser of (i) the Federal Funds Effective Rate and (ii)
the rate of interest applicable to such Loans, from the Business Day such funds
are received by the Administrative Agent in immediately available funds
(PROVIDED, if such funds are not received by the Administrative Agent by noon
(local time), such period shall commence on the Business Day immediately
following the day such funds are received) until such funds are paid to such
Lenders. The Administrative Agent is hereby authorized to charge the account of
the Borrower maintained with First Chicago for each payment of principal,
interest and fees as it becomes due hereunder.

         2.17. NOTES; TELEPHONIC NOTICES. Each Lender is hereby authorized to
record the principal amount of each of its Loans and each repayment on the
schedule attached to its Note, provided, however, that the failure to so record
shall not affect the Borrower's obligations under such Note. Each Lender's books
and records, including without limitation, the information, if any, recorded by
the Lender on the Schedule attached to its Note, shall be deemed to be PRIMA
FACIA correct. The Borrower hereby authorizes the Lenders and the Administrative
Agent to extend, convert or continue Advances, effect selections of Types of
Advances and to transfer funds based on telephonic notices made by any person or
persons the Administrative Agent or any Lender in good faith believes to be
acting on behalf of the Borrower. The Borrower agrees to deliver promptly to the
Administrative Agent a written confirmation signed by an Authorized Officer of
each telephonic notice, if such confirmation is requested by the Administrative
Agent or any Lender. If the written confirmation differs in any material respect
from the action taken by the Administrative Agent and the Lenders, the records
of the Administrative Agent and the Lenders shall govern absent manifest error.

         2.18. INTEREST PAYMENT DATES; INTEREST AND FEE BASIS. Interest accrued
on each Advance shall be payable on each Payment Date, commencing with the first
such date to occur after the date hereof, and at maturity, whether by
acceleration or otherwise. Interest accrued on each LIBOR Advance shall also be
payable on any date on which the LIBOR Advance is prepaid (provided that nothing
herein shall authorize a prepayment which is not otherwise permitted hereunder).
Interest and Facility Fees shall be calculated for actual days elapsed on the
basis of a 360-day year. Interest shall be payable for the day an Advance is
made but not for the day of any payment on the amount paid if payment is
received prior to noon (local time) at the place of payment. If any payment of
principal of or interest on an Advance shall become due on a day which is not a
Business Day, such payment shall be made on the next succeeding Business Day
and, in the case of a principal payment, such extension of time shall be
included in computing interest in connection with such payment.


                                      -19-
<PAGE>

         2.19. NOTIFICATION OF ADVANCES, INTEREST RATES AND PREPAYMENTS.
Promptly after receipt thereof (but in no event later than one Business Day
prior to the proposed Borrowing Date for a CBR Advance or three Business Days
prior to the proposed Borrowing Date for a LIBOR Advance) the Administrative
Agent will notify each Lender of the contents of each Borrowing Notice, Term
Loan Request, Extension Request, Conversion/Continuation Notice, and repayment
notice received by it hereunder. The Administrative Agent will notify each
Lender of the interest rate applicable to each LIBOR Advance promptly upon
determination of such interest rate and will give each Lender prompt notice of
each change in the Corporate Base Rate.

         2.20. LENDING INSTALLATIONS. Each Lender may book its Loans at any
Lending Installation selected by such Lender and may change its Lending
Installation from time to time. All terms of this Agreement shall apply to any
such Lending Installation and the Notes shall be deemed held by each Lender for
the benefit of such Lending Installation. Each Lender may, by written or telex
notice to the Administrative Agent and the Borrower, designate a Lending
Installation through which Loans will be made by it and for whose account Loan
payments are to be made.

         2.21. NON-RECEIPT OF FUNDS BY THE ADMINISTRATIVE AGENT. Unless the
Borrower or a Lender, as the case may be, notifies the Administrative Agent
prior to the date on which it is scheduled to make payment to the Administrative
Agent of (i) in the case of a Lender, the proceeds of a Loan or (ii) in the case
of the Borrower, a payment of principal, interest or fees to the Administrative
Agent for the account of the Lenders, that it does not intend to make such
payment, the Administrative Agent may assume that such payment has been made.
The Administrative Agent may, but shall not be obligated to, make the amount of
such payment available to the intended recipient in reliance upon such
assumption. If such Lender or the Borrower, as the case may be, has not in fact
made such payment to the Administrative Agent, the recipient of such payment
shall, on demand by the Administrative Agent, repay to the Administrative Agent
the amount so made available together with interest thereon in respect of each
day during the period commencing on the date such amount was so made available
by the Administrative Agent until the date the Administrative Agent recovers
such amount at a rate per annum equal to (i) in the case of payment by a Lender,
the Federal Funds Effective Rate for such day or (ii) in the case of payment by
the Borrower, the interest rate applicable to the relevant Loan.

         2.22. WITHHOLDING TAX EXEMPTION. At least five Business Days prior to
the first date on which interest or fees are payable hereunder for the account
of any Lender, each Lender that is not incorporated under the laws of the United
States of America, or a state thereof, agrees that it will deliver to each of
the Borrower and the Administrative Agent two duly completed copies of United
States Internal Revenue Service Form 1001 or 4224, certifying in either case
that such Lender is entitled to receive payments under this Agreement and the
Notes without deduction or withholding of any United States federal income
taxes. Each Lender which so delivers a Form 1001 or 4224 further undertakes to
deliver to each of the Borrower and the Administrative Agent two additional
copies of such form (or a successor form) on or before the date that such form
expires (currently, three successive calendar years for Form 1001 and one
calendar year for Form 4224) or becomes obsolete or after the occurrence of any
event requiring a change in the most recent forms so delivered by it, and such
amendments thereto or extensions or renewals thereof


                                      -20-
<PAGE>

as may be reasonably requested by the Borrower or the Administrative Agent, in
each case certifying that such Lender is entitled to receive payments under this
Agreement and the Notes without deduction or withholding of any United States
federal income taxes, unless an event (including without limitation any change
in treaty, law or regulation) has occurred prior to the date on which any such
delivery would otherwise be required which renders all such forms inapplicable
or which would prevent such Lender from duly completing and delivering any such
form with respect to it and such Lender advises the Borrower and the
Administrative Agent that it is not capable of receiving payments without any
deduction or withholding of United States federal income tax.

         2.23. USURY. This Agreement and each Note are subject to the express
condition that at no time shall the Borrower be obligated or required to pay
interest on the principal balance of the Loan at a rate which could subject any
Lender to either civil or criminal liability as a result of being in excess of
the Maximum Legal Rate. If by the terms of this Agreement or the Loan Documents,
the Borrower is at any time required or obligated to pay interest on the
principal balance due hereunder at a rate in excess of the Maximum Legal Rate,
the interest rate or the Default Rate, as the case may be, shall be deemed to be
immediately reduced to the Maximum Legal Rate and all previous payments in
excess of the Maximum Legal Rate shall be deemed to have been payments in
reduction of principal and not on account of the interest due hereunder. All
sums paid or agreed to be paid to a Lender for the use, forbearance, or
detention of the sums due under the Loan, shall, to the extent permitted by
applicable law, be amortized, prorated, allocated, and spread throughout the
full stated term of the Loan until payment in full so that the rate or amount of
interest on account of the Loan does not exceed the Maximum Legal Rate of
interest from time to time in effect and applicable to the Loan for so long as
the Loan is outstanding.

         2.24. APPLICATIONS OF MONEYS RECEIVED. All moneys collected or received
by the Administrative Agent on account of the Facility directly or indirectly,
shall be applied in the following order of priority:

               (i)   to the payment of all reasonable costs incurred in the
                     collection of such moneys of which the Administrative Agent
                     shall have given notice to the Borrower;

               (ii)  to the reimbursement of any yield protection due to the
                     Lenders in accordance with SECTION 4.1;

               (iii) to the payment of the Facility Fee to the Lenders, if then
                     due, in accordance with their Percentages and to the
                     payment of the Administrative Agent's Fee to the
                     Administrative Agent if then due;

               (iv)  (a) in case the entire unpaid principal of the Loan shall
                     not have become due and payable, the whole amount received
                     as interest then due to the Lenders (other than a
                     Defaulting Lender) as their respective Percentages appear,
                     together with the whole amount, if any, received as
                     principal to the Lenders as their respective Percentages
                     appear, or (b) in case the entire unpaid principal of the
                     Loan shall have become due and payable, as a


                                      -21-
<PAGE>

                     result of a Default or otherwise, to the payment of the
                     whole amount then due and payable on the Loan for
                     principal, together with interest thereon at the Default
                     Rate to the Lenders (other than a Defaulting Lender) as
                     their respective Percentages appear until paid in full; and

               (v)   to the payment of any sums due to each Defaulting Lender as
                     their respective Percentages appear (provided that
                     Administrative Agent shall have the right to set-off
                     against such sums any amounts due from such Defaulting
                     Lender).

         2.25. CONVERSION AND EXTENSION OPTIONS.

         (a) The Borrower shall have the option to (1) convert the Revolving
Credit Termination Balance to a term loan maturing on April 14, 2001 (in which
case any unfunded portion of the Commitments shall be cancelled and the Facility
Termination Date shall be extended to April 14, 2001), provided no Default
exists (a "Term Loan Request"), or (2) request an extension to April 14, 2001 of
both the Revolving Credit Termination Date and the Facility Termination Date (an
"Extension Request"). Borrower must provide any such Term Loan Request or
Extension Request to the Administrative Agent no more than sixty (60) days prior
to the initial Revolving Credit Termination Date, and no less than thirty (30)
days prior to the initial Revolving Credit Termination Date, provided that if
Borrower issues an Extension Request and such request is not approved by the
Required Lenders, Borrower may issue a Term Loan Request within five (5) days of
notification that such request was not approved. Promptly upon receipt from the
Borrower of any notice pursuant to this SECTION 2.25, the Administrative Agent
shall notify each Lender of the contents of such notice and, in the case of an
Extension Request, shall request that such Lender approve the Extension Request.
If the Borrower issues a Term Loan Request, the Revolving Credit Termination
Balance shall be converted to a term loan in the manner described above without
the need for any consent or approval of the Administrative Agent, the Arrangers,
the Lenders or any other party. Each Lender approving an Extension Request shall
deliver its written consent (a "Consent Notice") to the Borrower and the
Administrative Agent on or prior to the fifteenth (15th) day after the date on
which such notice is sent by the Administrative Agent to the Lenders (the
"Response Date"). Each Lender may give or withhold its consent to any Extension
Request in its sole discretion. The extension pursuant to any Extension Request
shall only be effective if such extension is approved by the Required Lenders,
and such extension shall not be effective with respect to any Lender which (i)
by notice (a "Withdrawal Notice") to the Borrower and the Administrative Agent
prior to the Response Date declines to consent to such Extension Request or (ii)
fails to respond to the Borrower and the Administrative Agent prior to the
Response Date (each such Lender, a "Withdrawing Lender" and each Lender other
than a Withdrawing Lender, a "Continuing Lender"). The Administrative Agent
shall promptly notify the Borrower and the Lenders whether the Extension Request
was approved or denied. If the consent of the Required Lenders to any such
Extension Request is received by the Administrative Agent on or prior to the
Response Date, (i) the new Revolving Credit Termination Date shall become
effective on the initial Revolving Credit Termination Date, (ii) the Agent shall
promptly notify the Borrower and each Lender of the new Revolving Credit
Termination Date, (iii) the Commitments of the Continuing Lenders shall be
extended on the initial Revolving Credit Termination Date and (iv) the
Withdrawing Lenders


                                      -22-
<PAGE>

shall be paid in full and their Commitments shall be cancelled or assumed by new
lenders selected by the Borrower and the Arrangers on the initial Revolving
Credit Termination Date. Upon repayment of a Withdrawing Lender's Loans, such
Lender shall be released from this Agreement, its Percentage of the Aggregate
Commitment, and all of the rights and obligations under the Agreement as of the
date of such release. Such Lender will remain responsible for all obligations
accruing prior to the date of such release. Concurrently with such release, the
Aggregate Commitment shall be reduced by the Commitment of the Lender that is
released and the Percentages shall be recalculated, unless the Borrower arranges
for a new lender to assume such Lender's Commitment by assignment in accordance
with the terms of this Agreement

         (b) A Withdrawing Lender shall be obliged, at the request of the
Borrower and the Arrangers and subject to such Withdrawing Lender receiving
payment in full of all amounts owing to it under this Agreement, to assign,
without recourse or warranty and by an assignment agreement substantially in the
form of "EXHIBIT H" attached hereto, all of its rights and obligations under
this Agreement to another financial institution nominated by the Borrower and
the Arrangers and willing to participate in the facility through the new
Revolving Credit Termination Date in place of such Withdrawing Lender; provided
that such assignee satisfies all of the requirements of this Agreement.

                             CHANGE IN CIRCUMSTANCES

         4.1. YIELD PROTECTION. If any law or any governmental or
quasi-governmental rule, regulation, policy, guideline or directive (whether or
not having the force of law), or any interpretation thereof, or the compliance
of any Lender therewith (the "Yield Related Law"),

              (i)   subjects any Lender or any applicable Lending Installation
                    to any tax, duty, charge or withholding on or from payments
                    due from the Borrower (excluding federal, state and local
                    income or franchise taxes on the overall income of any
                    Lender or applicable Lending Installation), or changes the
                    basis of taxation of payments to any Lender in respect of
                    its Loans or other amounts due it hereunder, or

              (ii)  imposes or increases or deems applicable any reserve,
                    assessment, insurance charge, special deposit or similar
                    requirement against assets of, deposits with or for the
                    account of, or credit extended by, any Lender or any
                    applicable Lending Installation (other than reserves and
                    assessments taken into account in determining the interest
                    rate applicable to LIBOR Advances), or


                                      -23-
<PAGE>

              (iii) imposes any other condition the result of which is to
                    increase the cost to any Lender or any applicable Lending
                    Installation of making, funding or maintaining loans or
                    reduces any amount receivable by any Lender or any
                    applicable Lending Installation in connection with loans, or
                    requires any Lender or any applicable Lending Installation
                    to make any payment calculated by reference to the amount of
                    loans held or interest received by it, by an amount deemed
                    material by such Lender,

then, within 15 days of demand by such Lender, the Borrower shall pay such
Lender that portion of such increased expense incurred or reduction in an amount
received which such Lender determines is attributable to making, funding and
maintaining its Loans and its Commitment. Within twenty (20) days after such
Lender makes any such demand, Borrower may repay all of such Lender's Loans, so
long as no Default exists at the time of such election and the Yield Related Law
affects the yield of less than all of the Lenders. Upon election of such
repayment option and repayment of such Lender's Loans, such Lender shall be
released from this Agreement, its Percentage of the Aggregate Commitment, and
all of the rights and obligations under the Agreement as of the date of such
release. Such Lender will remain responsible for all obligations accruing prior
to the date of such release. Concurrently with such release, the Aggregate
Commitment shall be reduced by the Commitment of the Lender that is released and
the Percentages shall be recalculated, unless the Borrower arranges for a new
lender to assume such Lender's Commitment by assignment in accordance with the
terms of this Agreement.

         4.2. CHANGES IN CAPITAL ADEQUACY REGULATIONS. If a Lender determines
the amount of capital required or expected to be maintained by such Lender, any
Lending Installation of such Lender or any corporation controlling such Lender
is increased as a result of a Change (as hereinafter defined), then, within
fifteen days of demand by such Lender, the Borrower shall pay such Lender the
amount necessary to compensate for any shortfall in the rate of return on the
portion on such increased capital which such Lender determines is attributable
to this Agreement, its Loans, or its obligation to make Loans hereunder (after
taking into account such Lender's policies as to capital adequacy). "CHANGE"
means (i) any change after the date of this Agreement in the Risk-Based Capital
Guidelines or (ii) any adoption of or change in any other law, governmental or
quasi-governmental rule, regulation, policy, guideline, interpretation, or
directive (whether or not having the force of law) after the date of this
Agreement which affects the amount of capital required or expected to be
maintained by any Lender or any Lending Installation or any corporation
controlling any Lender. "RISK-BASED CAPITAL GUIDELINES" means (i) the risk-based
capital guidelines in effect in the United States on the date of this Agreement,
including transition rules, and (ii) the corresponding capital regulations
promulgated by regulatory authorities outside the United States implementing the
July 1988 report of the Basle Committee on Banking Regulation and Supervisory
Practices Entitled "International Convergence of Capital Measurements and
Capital Standards," including transition rules, and any amendments to such
regulations adopted prior to the date of this Agreement.

         4.3. AVAILABILITY OF LIBOR ADVANCES. If any Lender determines that
maintenance of any of its LIBOR Loans at a suitable Lending Installation would
violate any applicable law, rule, regulation or directive, whether or not having
the force of law, the Administrative Agent shall suspend the availability of
LIBOR Advances and require any LIBOR Advances to be repaid; or


                                      -24-
<PAGE>

if the Required Lenders determine that (i) deposits of a type or maturity
appropriate to match fund LIBOR Advances are not available, the Administrative
Agent shall suspend the availability of LIBOR Advances with respect to any LIBOR
Advances made after the date of any such determination, or (ii) an interest rate
applicable to a LIBOR Advance does not accurately reflect the cost of making a
LIBOR Advance, then, if for any reason whatsoever the provisions of SECTION 4.1
are inapplicable, the Administrative Agent shall suspend the availability of
LIBOR Advances with respect to any LIBOR Advances made after the date of any
such determination.

         4.4. FUNDING INDEMNIFICATION. If any payment of a LIBOR Advance occurs
on a date which is not the last day of the applicable LIBOR Interest Period,
whether because of acceleration, prepayment or otherwise, or a LIBOR Advance is
not made on the date specified by the Borrower for any reason other than default
by the Lenders, the Borrower will indemnify each Lender for any loss or cost
incurred by it resulting therefrom, including, without limitation, any loss or
cost in liquidating or employing deposits acquired to fund or maintain the LIBOR
Advance.

         4.5. LENDER STATEMENTS; SURVIVAL OF INDEMNITY. To the extent reasonably
possible, each Lender shall designate an alternate Lending Installation with
respect to its LIBOR Loans to reduce any liability of the Borrower to such
Lender under SECTIONS 4.1 and 4.2 or to avoid the unavailability of a Type of a
LIBOR Advance under SECTION 4.3, so long as such designation is not
disadvantageous to such Lender. Each Lender shall deliver a written statement of
such Lender as to the amount due, if any, under SECTIONS 4.1, 4.2 or 4.4. Such
written statement shall set forth in reasonable detail the calculations upon
which such Lender determined such amount and shall be final, conclusive and
binding on the Borrower in the absence of manifest error. Determination of
amounts payable under such Sections in connection with a LIBOR Loan shall be
calculated as though each Lender funded its LIBOR Loan through the purchase of a
deposit of the type and maturity corresponding to the deposit used as a
reference in determining the LIBOR Rate applicable to such Loan, whether in fact
that is the case or not. Unless otherwise provided herein, the amount specified
in the written statement shall be payable on demand after receipt by the
Borrower of the written statement. The obligations of the Borrower under
SECTIONS 4.1, 4.2 and 4.4 shall survive payment of the Obligations and
termination of this Agreement.

                 ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES

         9.1. ACCELERATION. If any Default described in SECTION 8.7 or 8.8
occurs with respect to the Borrower, the obligations of the Lenders to make
Loans hereunder shall automatically terminate and the Obligations shall
immediately become due and payable without any election or action on the part of
the Administrative Agent or any Lender. If any other Default occurs, the
Required Lenders may terminate or suspend the obligations of the Lenders to make
Loans hereunder or declare the Obligations to be due and payable, or both,
whereupon the Obligations shall become immediately due and payable, without
presentment, demand, protest or notice of any kind, all of which the Borrower
hereby expressly waives.

         If, within ten (10) days after acceleration of the maturity of the
Obligations or termination of the obligations of the Lenders to make Loans
hereunder as a result of any Default (other than any Default as described in
SECTION 8.7 or 8.8 with respect to the Borrower) and before any judgment or
decree for the payment of the Obligations shall have been obtained or entered,
the Required Lenders (in their sole discretion) shall so direct, the
Administrative Agent shall, by notice to the Borrower, rescind and annul such
acceleration and/or termination.

         9.2. AMENDMENTS. Subject to the provisions of this ARTICLE IX, the
Required Lenders (or the Administrative Agent with the consent in writing of the
Required Lenders) and the Borrower may enter into agreements supplemental hereto
for the purpose of adding or modifying any provisions to the Loan Documents or
changing in any manner the rights of the Lenders or the Borrower hereunder or
waiving any Default hereunder; PROVIDED, HOWEVER, that no such supplemental
agreement shall, without the consent of the Arrangers, waive any Default under,
or modify or amend Sections 7.20(iii), (iv) or (v); and PROVIDED, FURTHER,
HOWEVER, that no such supplemental agreement shall, without the consent of all
Lenders:

              (i)   Extend the Facility Termination Date (other than pursuant to
                    SECTION 2.25 of this Agreement) or forgive all or any
                    portion of the principal amount of any Loan or accrued
                    interest thereon or the Facility Fee, reduce the Applicable
                    Margins on the underlying interest rate options or otherwise
                    modify or add to such interest rate options, or extend the
                    time of payment of any of the Obligations.

              (ii)  Release the General Partner from the Guaranty.

              (iii) Reduce the percentage specified in the definition of
                    Required Lenders.

              (iv)  Increase the amount of the Aggregate Commitment.

                                      -44-
<PAGE>

              (v)   Permit the Borrower to assign or allow another Person to
                    assume its rights under this Agreement.

              (vi)  Amend this SECTION 9.2.

No amendment of any provision of this Agreement relating to the
Administrative Agent shall be effective without the written consent of the
Administrative Agent, and no amendment increasing the Commitment of any
Lender shall be effective without the written consent of such Lender.

         9.3. PRESERVATION OF RIGHTS. No delay or omission of the Lenders or the
Administrative Agent to exercise any right under the Loan Documents shall impair
such right or be construed to be a waiver of any Default or an acquiescence
therein, and the making of a Loan notwithstanding the existence of a Default or
the inability of the Borrower to satisfy the conditions precedent to such Loan
shall not constitute any waiver or acquiescence. Any single or partial exercise
of any such right shall not preclude other or further exercise thereof or the
exercise of any other right, and no waiver, amendment or other variation of the
terms, conditions or provisions of the Loan Documents whatsoever shall be valid
unless in writing signed by the Lenders required pursuant to SECTION 9.2, and
then only to the extent in such writing specifically set forth. All remedies
contained in the Loan Documents or by law afforded shall be cumulative and all
shall be available to the Administrative Agent and the Lenders until the
Obligations have been paid in full.

interest and penalties, if any.

                                   ARTICLE XI

              THE ADMINISTRATIVE AGENT AND AGREEMENTS AMONG LENDERS

         11.1. APPOINTMENT. Subject to the provisions of SECTION 11.11, The
First National Bank of Chicago is hereby appointed Administrative Agent
hereunder and under each other Loan Document, and each of the Lenders
irrevocably authorizes the Administrative Agent to act as the agent of such
Lender. The Administrative Agent agrees to act as such upon the express
conditions contained in this ARTICLE XI. The Administrative Agent shall not have
a fiduciary relationship in respect of the Borrower or any Lender by reason of
this Agreement.

         11.2. POWERS. The Administrative Agent shall have and may exercise such
powers under the Loan Documents as are specifically delegated to the
Administrative Agent by the terms of each thereof, together with such powers as
are reasonably incidental thereto. The Administrative Agent shall have no
implied duties to the Lenders, or any obligation to the Lenders to take any
action thereunder except any action specifically provided by the Loan Documents
to be taken by the Administrative Agent.

         11.3. GENERAL IMMUNITY. Neither the Administrative Agent nor any of its
directors, officers, agents or employees shall be liable to the Borrower, the
Lenders or any Lender for any action taken or omitted to be taken by it or them
hereunder or under any other Loan Document or in connection herewith or
therewith except for its or their own gross negligence or willful misconduct.

         11.4. NO RESPONSIBILITY FOR LOANS, RECITALS, ETC. Neither the
Administrative Agent nor any of its directors, officers, agents or employees
shall be responsible for or have any duty to ascertain, inquire into, or verify

of the covenants or agreements of any obligor under any Loan Document,
including, without limitation, any agreement by an obligor to furnish
information directly to each Lender; (iii) the satisfaction of any condition
specified in ARTICLE V, except receipt of items required to be delivered to the
Administrative Agent; (iv) the validity, effectiveness or genuineness of any
Loan Document or any other instrument or writing furnished in connection
therewith; or (v) the value, sufficiency, creation, perfection or priority of
any interest in any collateral security. The Administrative Agent shall have no
duty to disclose to the Lenders information that is not required to be furnished
by the Borrower to the Administrative Agent at such time, but is voluntarily
furnished by the Borrower to the Administrative Agent (either in its capacity as
Administrative Agent or in its individual capacity).

         11.5. ACTION ON INSTRUCTIONS OF LENDERS. The Administrative Agent shall
in all cases be fully protected in acting, or in refraining from acting,
hereunder and under any other Loan Document in accordance with written
instructions signed by the Required Lenders, and such instructions and any
action taken or failure to act pursuant thereto shall be binding on all of the
Lenders and on all holders of Notes. The Administrative Agent shall be fully
justified in failing or refusing to take any action hereunder and under any
other Loan Document unless it shall first be indemnified to its satisfaction by
the Lenders pro rata against any and all liability, cost and expense that it may
incur by reason of taking or continuing to take any such action.


                                      -48-
<PAGE>

         11.6. EMPLOYMENT OF AGENTS AND COUNSEL. The Administrative Agent may
execute any of its duties as Administrative Agent hereunder and under any other
Loan Document by or through employees, agents, and attorneys-in-fact and so long
as it exercises reasonable care in the selection of such parties, the
Administrative Agent shall not be answerable to the Lenders, except as to money
or securities received by it or its authorized agents, for the default or
misconduct of any such parties. The Administrative Agent shall be entitled to
advice of counsel concerning all matters pertaining to the agency hereby created
and its duties hereunder and under any other Loan Document.

         11.7. RELIANCE ON DOCUMENTS; COUNSEL. The Administrative Agent shall be
entitled to rely upon any Note, notice, consent, certificate, affidavit, letter,
telegram, statement, paper or document believed by it to be genuine and correct
and to have been signed or sent by the proper person or persons, and, in respect
to legal matters, upon the opinion of counsel selected by the Administrative
Agent, which counsel may be employees of the Administrative Agent.

         11.8. ADMINISTRATIVE AGENT'S REIMBURSEMENT AND INDEMNIFICATION. The
Lenders agree to reimburse and indemnify the Administrative Agent ratably in
proportion to their respective Commitments (i) for any reasonable amounts not
reimbursed by the Borrower for which the Administrative Agent is entitled to
reimbursement by the Borrower under the Loan Documents including reasonable
out-of-pocket expenses in connection with the preparation, execution, delivery
of the Loan Documents, (ii) for any other reasonable out-of-pocket expenses
incurred by the Administrative Agent on behalf of the Lenders, in connection
with the administration and enforcement of the Loan Documents and (iii) for any
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind and nature whatsoever which may be
imposed on, incurred by or asserted against the Administrative Agent in any way
relating to or arising out of the Loan Documents or any other document delivered
in connection therewith or the transactions contemplated thereby, or the
enforcement of any of the terms thereof or of any such other documents, PROVIDED
that no Lender shall be liable for (i) any of the foregoing to the extent they
arise from the gross negligence or willful misconduct of the Administrative
Agent, or (ii) any costs or expenses of the Administrative Agent's in-house
legal staff and personnel. The obligations of the Lenders under this SECTION
11.8 shall survive payment of the Obligations and termination of this Agreement.

         11.9. RIGHTS AS A LENDER. In the event the Administrative Agent is a
Lender, the Administrative Agent shall have the same rights and powers and the
same duties and obligations hereunder and under any other Loan Document as any
Lender and may exercise the same as though it were not the Administrative Agent,
and the term "Lender" or "Lenders" shall, at any time when the Administrative
Agent is a Lender, unless the context otherwise indicates, include the
Administrative Agent in its individual capacity. The Administrative Agent may
accept deposits from, lend money to, and generally engage in any kind of trust,
debt, equity or other transaction, in addition to those contemplated by this
Agreement or any other Loan Document, with the Borrower or any of its
Subsidiaries in which the Borrower or such Subsidiary is not restricted hereby
from engaging with any other Person.

         11.10. LENDER CREDIT DECISION. Each Lender acknowledges that it has,
independently and without reliance upon the Administrative Agent or any other
Lender and based on the


                                      -49-
<PAGE>

financial statements prepared by the Borrower and such other documents and
information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement and the other Loan Documents. Each Lender
also acknowledges that it will, independently and without reliance upon the
Administrative Agent or any other Lender and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking action under this Agreement and the
other Loan Documents.

         11.11. SUCCESSOR ADMINISTRATIVE AGENT. The Administrative Agent may
resign at any time by giving written notice thereof to the Lenders and the
Borrower, and the Administrative Agent shall be deemed to have automatically
resigned if it is no longer a Lender, such resignation in either case to be
effective upon the appointment of a successor Administrative Agent or, if no
successor Administrative Agent has been appointed, forty-five days after the
retiring Administrative Agent gives notice of its intention to resign or ceases
to be a Lender, as the case may be. The Administrative Agent may be removed at
any time with good cause by written notice received by the Administrative Agent
from the Required Lenders, such removal to be effective on the date specified by
the Required Lenders. Upon any such resignation or removal, the Required Lenders
shall have the right to appoint, on behalf of the Borrower and the Lenders, a
successor Administrative Agent, PROVIDED, HOWEVER, that Wells Fargo Bank,
National Association (but not its successors and assigns) may, at its option,
appoint itself as successor Administrative Agent. If no successor Administrative
Agent shall have been so appointed by the Required Lenders within thirty days
after the resigning Administrative Agent's giving notice of its intention to
resign, then the resigning Administrative Agent may appoint, on behalf of the
Borrower and the Lenders, a successor Administrative Agent. If the
Administrative Agent has resigned or been removed and no successor
Administrative Agent has been appointed within 45 days, the Lenders shall
perform all the duties of the Administrative Agent hereunder and the Borrower
shall make all payments in respect of the Obligations to the applicable Lender
and for all other purposes shall deal directly with the Lenders. No successor
Administrative Agent shall be deemed to be appointed hereunder until such
successor Administrative Agent has accepted the appointment. Any such successor
Administrative Agent shall be a commercial bank (or a subsidiary thereof) having
capital and retained earnings of at least $500,000,000, except that if the
successor Administrative Agent is a subsidiary of a bank, such capital and
retained earnings requirement shall apply only to the parent bank. Upon the
acceptance of any appointment as Administrative Agent hereunder by a successor
Administrative Agent, such successor Administrative Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the resigning or removed Administrative Agent. Upon the effectiveness of the
resignation or removal of the Administrative Agent, the resigning or removed
Administrative Agent and the successor Administrative Agent shall pro rate any
agency fees, and the resigning or removed Administrative Agent shall be
discharged from its duties and obligations hereunder and under the Loan
Documents. After the effectiveness of the resignation or removal of an
Administrative Agent, the provisions of this ARTICLE XI shall continue in effect
for the benefit of such Administrative Agent in respect of any actions taken or
omitted to be taken by it while it was acting as the Administrative Agent
hereunder and under the other Loan Documents.

<PAGE>

         11.12. NOTICE OF DEFAULTS. If a Lender becomes aware of a Default or
Unmatured Default, such Lender shall notify the Administrative Agent of such
fact. Upon receipt of such notice that a Default or Unmatured Default has
occurred, the Administrative Agent shall notify each of the Lenders of such
fact.

         11.13. REQUESTS FOR APPROVAL. If the Administrative Agent requests in
writing the consent or approval of a Lender, such Lender shall respond and
either approve or disapprove definitively in writing to the Administrative Agent
within ten Business Days (or sooner if such notice specifies a shorter period
for responses based on Administrative Agent's good faith determination that
circumstances exist warranting its request for an earlier response) after such
written request from the Administrative Agent. If the Lender does not so
respond, that Lender shall be deemed to have approved the request, provided the
initial notice references such deemed approval.

         11.14. COPIES OF DOCUMENTS. Within fifteen Business Days after a
request by a Lender to the Administrative Agent for documents furnished to the
Administrative Agent by the Borrower, the Administrative Agent shall provide
copies of such documents to such Lender.

         11.15. DEFAULTING LENDERS. At such time as a Lender becomes a
Defaulting Lender, such Defaulting Lender's right to vote on matters which are
subject to the consent or approval of the Required Lenders, each affected Lender
or all Lenders shall be immediately suspended until such time as the Lender is
no longer a Defaulting Lender. If a Defaulting Lender has failed to fund its pro
rata share of any Advance and until such time as such Defaulting Lender
subsequently funds its pro rata share of such Advance, all Obligations owing to
such Defaulting Lender hereunder shall be subordinated in right of payment, as
provided in the following sentence, to the prior payment in full of all
principal of, interest on and fees relating to the Loans funded by the other
Lenders in connection with any such Advance in which the Defaulting Lender has
not funded its pro rata share (such principal, interest and fees being referred
to as "Senior Loans" for the purposes of this section). All amounts paid by the
Borrower and otherwise due to be applied to the Obligations owing to such
Defaulting Lender pursuant to the terms hereof shall be distributed by the
Administrative Agent to the other Lenders in accordance with their respective
pro rata shares (recalculated for the purposes hereof to exclude the Defaulting
Lender) until all Senior Loans have been paid in full. After the Senior Loans
have been paid in full equitable adjustments will be made in connection with
future payments by the Borrower to the extent a portion of the Senior Loans had
been repaid with amounts that otherwise would have been distributed to a
Defaulting Lender but for the operation of this SECTION 11.15. This provision
governs only the relationship among the Administrative Agent, each Defaulting
Lender and the other Lenders; nothing hereunder shall limit the obligation of
the Borrower to repay all Loans in accordance with the terms of this Agreement.
The provisions of this section shall apply and be effective regardless of
whether a Default occurs and is continuing, and notwithstanding (i) any other
provision of this Agreement to the contrary, (ii) any instruction of the
Borrower as to its desired application of payments or (iii) the suspension of
such Defaulting Lender's right to vote on matters which are subject to the
consent or approval of the Required Lenders or all Lenders.

                            SETOFF; RATABLE PAYMENTS

         12.1. SETOFF. In addition to, and without limitation of, any rights of
the Lenders under applicable law, if the Borrower becomes insolvent, however
evidenced, or any Default or Unmatured Default occurs, any and all deposits
(including all account balances, whether provisional or final and whether or not
collected or available) and any other Indebtedness at any time held or owing by
any Lender to or for the credit or account of the Borrower may be offset and
applied toward the payment of the Obligations owing to such Lender, whether or
not the Obligations, or any part hereof, shall then be due. The Lenders agree
for the benefit of each other Lender (but not the Borrower) that any set-off
shall first be applied to the Obligations before being applied to any other
Indebtedness owing to such Lender.

         12.2. RATABLE PAYMENTS. If any Lender, whether by setoff or otherwise,
has payment made to it upon its Loans (other than payments received pursuant to
SECTIONS 4.1, 4.2 or 4.4) in a greater proportion than that received by any
other Lender, such Lender agrees, promptly upon demand, to purchase a portion of
the Loans held by the other Lenders so that after such purchase each Lender will
hold its ratable proportion of Loans. If any Lender, whether in connection with
setoff or amounts which might be subject to setoff or otherwise, receives
collateral or other protection for its Obligations or such amounts which may be
subject to setoff, such Lender agrees, promptly upon demand, to take such action
necessary such that all Lenders share in the benefits of such collateral ratably
in proportion to their Loans. In case any such payment is disturbed by legal
process, or otherwise, appropriate further adjustments shall be made.


                                  ARTICLE XIII

                BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

         13.1. SUCCESSORS AND ASSIGNS. The terms and provisions of the Loan
Documents shall be binding upon and inure to the benefit of the Borrower and the
Lenders and their respective successors and assigns, except that (i) the
Borrower shall not have the right to assign its rights or obligations under the
Loan Documents and (ii) any assignment by any Lender must be made in compliance
with SECTION 13.3. Notwithstanding clause (ii) of this SECTION 13.1, any Lender
may at any time, without the consent of the Borrower or the Administrative
Agent, assign all or any portion of its rights under this Agreement and its
Notes to a Federal Reserve Bank; provided, however, that no such assignment
shall release the transferor Lender from its obligations hereunder. The
Administrative Agent may treat the payee of any Note as the owner thereof for
all purposes hereof unless and until such payee complies with SECTION 13.3 in
the case of an assignment thereof or, in the case of any other transfer, a
written notice of the transfer is filed with the Administrative Agent. Any
assignee or transferee of a Note agrees by acceptance thereof to be bound by all
the terms and provisions of the Loan Documents. Any request, authority or
consent of any Person, who at the time of making such request or giving such
authority or consent is the holder of any Note, shall be conclusive and binding
on any subsequent holder, transferee or assignee of such Note or of any Note or
Notes issued in exchange therefor.

         13.2. PARTICIPATIONS.

               13.2.1 PERMITTED PARTICIPANTS; EFFECT. Any Lender, in the
         ordinary course of its business and in accordance with applicable law,
         at any time, may sell participating interests in any Loan owing to
         such Lender, any Note held by such Lender, any Commitment of such
         Lender or any other interest of such Lender under the Loan Documents.
         Any Person to whom such a participating interest is sold is a
         "Participant". In the event of any such sale by a Lender of
         participating interests to a Participant, such Lender's obligations
         under the Loan Documents shall remain unchanged, such Lender shall
         remain solely responsible to the other parties hereto for the
         performance of such obligations, such Lender shall remain the holder
         of any such Note for all purposes under the Loan Documents, all
         amounts payable by the Borrower under this Agreement shall be
         determined as if such Lender had not sold such participating
         interests, and the Borrower and the Administrative Agent shall
         continue to deal solely and directly with such Lender in connection
         with such Lender's rights and obligations under the Loan Documents.

               13.2.2 VOTING RIGHTS. Each Lender shall retain the sole right to
         approve, without the consent of any Participant, any amendment,
         modification or waiver of any provision of the Loan Documents other
         than any amendment, modification or waiver with respect to any Loan or
         Commitment in which such Participant has an interest which forgives
         principal, interest or fees or reduces the interest rate or fees
         payable with respect to any such Loan or Commitment or postpones any
         date fixed for any regularly-scheduled payment of principal of, or
         interest or fees on, any such Loan or Commitment or releases any
         guarantor of any such Loan or releases any substantial portion of
         collateral, if any, securing such Loan.

               13.2.3 BENEFIT OF SETOFF. The General Partner and the Borrower
         each agrees that each Participant shall be deemed to have the right of
         setoff provided in SECTION 12.1 in respect of its participating
         interest in amounts owing under the Loan Documents to the same extent
         as if the amount of its participating interest were owing directly to
         it as a Lender under the Loan Documents, provided that each Lender
         shall retain the right of setoff provided in SECTION 12.1 with respect
         to the amount of participating interests sold to each Participant. The
         Lenders agree to share with each Participant, and each Participant, by
         exercising the right of setoff provided in SECTION 13.1, agrees to
         share with each Lender, any amount received pursuant to the exercise
         of its right of setoff, such amounts to be shared in accordance with
         SECTION 12.2 as if each Participant were a Lender.

         13.3. ASSIGNMENTS.

               13.3.1 PERMITTED ASSIGNMENTS. Any Lender, in the ordinary course
         of its business and in accordance with applicable law, at any time,
         may assign all or any portion (greater than or equal to $5,000,000 per
         assignee) of its rights and obligations under the Loan Documents. Any
         Person to whom such rights and obligations are assigned is a
         "Purchaser". Such assignment shall be substantially in the form of
         EXHIBIT H hereto or in such other form as may be agreed to by the
         parties thereto.


                                      -53-
<PAGE>


               The consent of the Administrative Agent shall be required prior
         to an assignment becoming effective with respect to a Purchaser which
         is not a Lender or an Affiliate thereof, except no consent shall be
         required if a Default exists. Such consent shall not be unreasonably
         withheld.

               13.3.2 EFFECT; EFFECTIVE DATE. Upon (i) delivery to the
         Administrative Agent of a notice of assignment, substantially in the
         form attached as EXHIBIT I to EXHIBIT H hereto (a "NOTICE OF
         ASSIGNMENT"), together with any consents required by Section 13.3.1,
         and (ii) payment of a $3,000 fee to the Administrative Agent for
         processing such assignment (unless the assignment is to an affiliate
         of the Lender in which case no fee shall be charged), such assignment
         shall become effective on the effective date specified in such Notice
         of Assignment. The Notice of Assignment shall contain a representation
         by the Purchaser to the effect that none of the consideration used to
         make the purchase of the Commitment and Loans under the applicable
         assignment agreement are "plan assets" as defined under ERISA and that
         the rights and interests of the Purchaser in and under the Loan
         Documents will not be "plan assets" under ERISA. On and after the
         effective date of such assignment, such Purchaser shall for all
         purposes be a Lender party to this Agreement and any other Loan
         Document executed by the Lenders and shall have all the rights and
         obligations of a Lender under the Loan Documents, to the same extent
         as if it were an original party hereto, and no further consent or
         action by the Borrower, the Lenders or the Administrative Agent shall
         be required to release the transferor Lender with respect to the
         percentage of the Aggregate Commitment and Loans assigned to such
         Purchaser. Upon the consummation of any assignment to a Purchaser
         pursuant to this SECTION 13.3.2, the transferor Lender, the
         Administrative Agent and the Borrower shall make appropriate
         arrangements so that replacement Notes are issued to such transferor
         Lender and new Notes or, as appropriate, replacement Notes, are issued
         to such Purchaser, in each case in principal amounts reflecting their
         Commitment, as adjusted pursuant to such assignment.

         13.4. INTENTIONALLY OMITTED

         13.5. DISSEMINATION OF INFORMATION. The General Partner and the
Borrower authorize each Lender to disclose to any Participant or Purchaser or
any other Person acquiring an interest in the Loan Documents by operation of law
(each a "TRANSFEREE") and any prospective Transferee any and all information in
such Lender's possession concerning the creditworthiness of the General Partner,
the Borrower and their Subsidiaries.

         13.6. TAX TREATMENT. If any interest in any Loan Document is
transferred to any Transferee which is organized under the laws of any
jurisdiction other than the United States or any State thereof, the transferor
Lender shall cause such Transferee, concurrently with the effectiveness of such
transfer, to comply with the provisions of SECTION 2.22.

respect to borrowing notices, all notices and other communications provided to
any party hereto under this Agreement or any other Loan Document shall be in
writing or by telex or by facsimile and addressed or delivered to such party at
its address set forth below its signature hereto or at such other address as may
be designated by such party in a notice to the other parties. Any notice, if
mailed and properly addressed with postage prepaid, shall be deemed given when
received; any notice, if transmitted by telex or facsimile, shall be deemed
given when transmitted (answerback confirmed in the case of telexes).

         14.2. CHANGE OF ADDRESS. The General Partner, the Borrower, the
Administrative Agent, the Arrangers and any Lender may each change the address
for service of notice upon it by a notice in writing to the other parties
hereto.


                                   ARTICLE XV

                                  COUNTERPARTS

         This Agreement may be executed in any number of counterparts, all of
which taken together shall constitute one agreement, and any of the parties
hereto may execute this Agreement by signing any such counterpart. This
Agreement shall be effective when it has been executed by the Borrower, the
Administrative Agent and the Lenders and each party has notified the
Administrative Agent by telex or telephone, that it has taken such action.


                                      -55-

                                                                 July ___, 1999

The Administrative Agent and
 the Lenders who are parties to the
 Credit Agreement described below

Gentlemen/Ladies:

       We are counsel for Duke-Weeks Realty Limited Partnership, an Indiana
limited partnership (the "Borrower"), and Duke Realty Corporation, an Indiana
corporation (the "General Partner" and, collectively with the Borrower, the
"Duke Entities"), and have represented the Duke Entities in connection with
their execution and delivery of a Revolving Credit Agreement among the Duke
Entities, The First National Bank of Chicago, individually and as Administrative
Agent, Banc One Capital Markets, Inc. as Lead Arranger and Joint Book Runner,
Wachovia Securities, Inc., as Lead Arranger and Joint Book Runner, Wells Fargo
Bank, National Association individually and as Co-Arranger, and the Lenders
named therein, providing for Advances in an aggregate principal amount of up to
$300,000,000 at any one time outstanding, dated as of July__, 1999 (the
"Agreement"). All capitalized terms used in this opinion and not otherwise
defined shall have the meanings attributed to them in the Agreement.

       We have examined the Duke Entities' articles of incorporation, by-laws,
resolutions, certificate of limited partnership, partnership agreement, the Loan
Documents and such other matters of fact and law which we deem necessary in
order to render this opinion. Based upon the foregoing, it is our opinion that:

         1. The General Partner, the Borrower and each of their Subsidiaries are
either duly incorporated corporations or duly qualified and formed limited
partnerships, validly existing and in good standing under the laws of their
states of incorporation or formation.

         2. The execution and delivery of the Loan Documents by the Duke
Entities and the performance by the Duke Entities of their obligations under the
Loan Documents have been duly authorized by all necessary corporate action
and/or proceedings on the part of the Duke Entities and will not:

            (a) require any consent of the Duke Entities' shareholders or
         limited partners;

            (b) violate any law, rule, regulation, order, writ, judgment,
         injunction, decree or award binding on the Duke Entities or any of
         their Subsidiaries or the Duke Entities' or any Subsidiary's articles
         of incorporation, by-laws, certificate of limited partnership,
         partnership agreement, or any indenture, instrument or agreement
         binding upon the Duke Entities or any of their Subsidiaries; or

            (c) result in, or require, the creation or imposition of any Lien
         pursuant to the provisions of any indenture, instrument or agreement
         binding upon the Duke Entities or any of their Subsidiaries.


<PAGE>

         3. The Loan Documents have been duly executed and delivered by the Duke
Entities and constitute legal, valid and binding obligations of the Duke
Entities enforceable in accordance with their terms except to the extent the
enforcement thereof may be limited by bankruptcy, insolvency or similar laws
affecting the enforcement of creditors' rights generally and subject also to the
availability of equitable remedies if equitable remedies are sought.

         4. There is no litigation or proceeding against the Duke Entities or
any of their Subsidiaries which, if adversely determined, could have a Material
Adverse Effect.

         5. No approval, authorization, consent, adjudication or order of any
governmental authority, which has not been obtained by the Duke Entities or any
of their Subsidiaries, is required to be obtained by the Duke Entities or any of
their Subsidiaries in connection with the execution and delivery of the Loan
Documents, the borrowings under the Agreement or in connection with the payment
by the Duke Entities of their obligations under the Loan Documents.

         6. The General Partner qualifies as a real estate investment trust in
accordance with all applicable requirements of the Internal Revenue Code.

                              ASSIGNMENT AGREEMENT

       This Assignment Agreement (this "Assignment Agreement") between _________
______________ (the "Assignor") and (the "Assignee") is dated as of ___________,
____. The parties hereto agree
as follows:

1.   PRELIMINARY STATEMENT. The Assignor is a party to a Credit Agreement
(which, as it may be amended, modified, renewed or extended from time to time is
herein called the "Credit Agreement") described in Item 1 of Schedule 1 attached
hereto ("Schedule 1"). Capitalized terms used herein and not otherwise defined
herein shall have the meanings attributed to them in the Credit Agreement.

2.   ASSIGNMENT AND ASSUMPTION. The Assignor hereby sells and assigns to the
Assignee, and the Assignee hereby purchases and assumes from the Assignor, an
interest in and to the Assignor's rights and obligations under the Credit
Agreement such that after giving effect to such assignment the Assignee shall
have purchased pursuant to this Assignment Agreement the percentage interest
specified in Item 3 of Schedule 1 of all outstanding rights and obligations
under the Credit Agreement and the other Loan Documents. The aggregate
Commitment (or Loans, if the applicable Commitment has been terminated)
purchased by the Assignee hereunder is set forth in Item 4 of Schedule 1.

3.   EFFECTIVE DATE. The effective date of this Assignment Agreement (the
"Effective Date") shall be the later of the date specified in Item 5 of
Schedule 1 or two (2) Business Days (or such shorter period agreed to by the
Administrative Agent) after a Notice of Assignment substantially in the form of
Exhibit "I" attached hereto has been delivered to the Agent. Such Notice of
Assignment must include the consent of the Agent required by SECTION 13.3.1 of
the Credit Agreement. In no event will the Effective Date occur if the payments
required to be made by the Assignee to the Assignor on the Effective Date under
SECTIONS 4 AND 5 hereof are not made on the proposed Effective Date. The
Assignor will notify the Assignee of the proposed Effective Date no later than
the Business Day prior to the proposed Effective Date. As of the Effective Date,
(i) the Assignee shall have the rights and obligations of a Lender under the
Loan Documents with respect to the rights and obligations assigned to the
Assignee hereunder and (ii) the Assignor shall relinquish its rights and be
released from its corresponding obligations under the Loan Documents with
respect to the rights and obligations assigned to the Assignee hereunder.

4.   PAYMENTS OBLIGATIONS. On and after the Effective Date, the Assignee
shall be entitled to receive from the Agent all payments of principal, interest
and fees with respect to the interest assigned hereby. The Assignee shall
advance funds directly to the Agent with respect to all Loans and reimbursement
payments made on or after the Effective Date with respect to the interest
assigned hereby. [In consideration for the sale and assignment of Loans
hereunder, (i) the Assignee shall pay the Assignor, on the Effective Date, an
amount equal to the principal amount of the portion of all CBR Loans assigned to
the Assignee hereunder and (ii) with respect to each LIBOR Loan made by the
Assignor and assigned to the Assignee hereunder which is outstanding on the
Effective Date, (a) on the last day of the LIBOR Interest Period therefor or
(b) on such earlier date agreed to by the Assignor and the Assignee or (c) on
the date on which any such LIBOR Loan either becomes due (by acceleration or
otherwise) or is prepaid (the date as described in the foregoing clauses (a),
(b) or (c) being hereinafter referred to as the "LIBOR Due Date"), the Assignee
shall pay the Assignor an amount equal to the principal amount of the portion of
such LIBOR Loan assigned to the Assignee which is outstanding on the LIBOR Due
Date. If the Assignor and the Assignee agree that the applicable LIBOR Due Date
for such LIBOR Loan shall be the Effective Date, they shall agree, solely for
purposes of dividing interest paid by the Borrower on such

<PAGE>


LIBOR Loan, to an alternate interest rate applicable to the portion of such Loan
assigned hereunder for the period from the Effective Date to the end of the
related LIBOR Interest Period (the "Agreed Interest Rate") and any interest
received by the Assignee in excess of the Agreed Interest Rate, with respect to
such LIBOR Loan for such period, shall be remitted to the Assignor. [In the
event interest for any period from the Effective Date to but not including the
LIBOR Due Date is not paid when due by the Borrower with respect to any LIBOR
Loan sold by the Assignor to the Assignee hereunder, the Assignee shall pay to
the Assignor interest for such period on the portion of such LIBOR Loan sold by
the Assignor to the Assignee hereunder at the applicable rate provided by the
Credit Agreement.] In the event a prepayment of any LIBOR Loan which is existing
on the Effective Date and assigned by the Assignor to the Assignee hereunder
occurs after the Effective Date but before the applicable LIBOR Due Date, the
Assignee shall remit to the Assignor any excess of the funding indemnification
amount paid by the Borrower under Section 3.4 of the Credit Agreement an account
of such prepayment with respect to the portion of such LIBOR Loan assigned to
the Assignee hereunder over the amount which would have been paid if such
prepayment amount were calculated based on the Agreed Interest Rate and only
covered the portion of the LIBOR Interest Period after the Effective Date. The
Assignee will promptly remit to the Assignor (i) the portion of any principal
payments assigned hereunder and received from the Agent with respect to any
LIBOR Loan prior to its LIBOR Due Date and (ii) any amounts of interest on Loans
and fees received from the Agent which relate to the portion of the Loans
assigned to the Assignee hereunder for periods prior to the Effective Date, in
the case of CBR Loans or fees, or the LIBOR Due Date, in the case of LIBOR
Loans, and not previously paid by the Assignee to the Assignor.]* In the event
that either party hereto receives any payment to which the other party hereto is
entitled under this Assignment Agreement, then the party receiving such amount
shall promptly remit it to the other party hereto.

*EACH ASSIGNOR MAY INSERT ITS STANDARD PAYMENT PROVISIONS IN LIEU OF THE PAYMENT
TERMS INCLUDED IN THIS EXHIBIT.

5.   FEES PAYABLE BY THE ASSIGNEE. The Assignee shall pay to the Assignor a
fee on each day on which a payment of interest or Facility Fees is made under
the Credit Agreement with respect to the amounts assigned to the Assignee
hereunder (other than a payment of interest or Facility Fees attributable to the
period prior to the Effective Date or, in the case of LIBOR Loans, the Payment
Date, which the Assignee is obligated to deliver to the Assignor pursuant to
SECTION 4 hereof). The amount of such fee shall be the difference between
(i) the interest or fee, as applicable, paid with respect to the amounts
assigned to the Assignee hereunder and (ii) the interest or fee, as applicable,
which would have been paid with respect to the amounts assigned to the Assignee
hereunder if each interest rate was calculated at the rate of % rather than the
actual percentage used to calculate the interest rate paid by the Borrower or if
the Facility Fee was calculated at the rate of % rather than the actual
percentage used to calculate the Facility Fee paid by the Borrower, as
applicable. In addition, the Assignee agrees to pay % of the fee required to be
paid to the Agent in connection with this Assignment Agreement.

6.   REPRESENTATIONS OF THE ASSIGNOR; LIMITATIONS ON THE ASSIGNOR'S
LIABILITY. The Assignor represents and warrants that it is the legal and
beneficial owner of the interest being assigned by it hereunder and that such
interest is free and clear of any adverse claim created by the Assignor. It is

without recourse to the Assignor and that the Assignor makes no other
representation or warranty of any kind to the Assignee. Neither the Assignor nor
any of its officers, directors, employees, agents or attorneys shall be
responsible for (i) the due execution, legality, validity, enforceability,
genuineness, sufficiency or collectability of any Loan Document, including
without limitation, documents granting the Assignor and the other Lenders a
security interest in assets of the Borrower or any guarantor, (ii) any
representation, warranty or statement made in or in connection with any of the
Loan Documents, (iii) the financial condition or creditworthiness of the
Borrower or any guarantor, (iv) the performance of or compliance with any of the
terms or provisions of any of the Loan Documents, (v) inspecting any of the
Property, books or records of the Borrower, (vi) the validity, enforceability,
perfection, priority, condition, value or


<PAGE>


sufficiency of any collateral securing or purporting to secure the Loans or
(vii) any mistake, error of judgment, or action taken or omitted to be taken in
connection with the Loans or the Loan Documents.

7.   REPRESENTATIONS OF THE ASSIGNEE. The Assignee (i) confirms that it has
received a copy of the Credit Agreement, together with copies of the financial
statements requested by the Assignee and such other documents and information as
it has deemed appropriate to make its own credit analysis and decision to enter
into this Assignment Agreement, (ii) agrees that it will, independently and
without reliance upon the Agent, the Assignor or any other Lender and based on
such documents and information at it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
the Loan Documents, (iii) appoints and authorizes the Agent to take such action
as agent on its behalf and to exercise such powers under the Loan Documents as
are delegated to the Agent by the terms thereof, together with such powers as
are reasonably incidental thereto, (iv) agrees that it will perform in
accordance with their terms all of the obligations which by the terms of the
Loan Documents are required to be performed by it as a Lender, (v) agrees that
its payment instructions and notice instructions are as set forth in the
attachment to Schedule 1, (vi) confirms that none of the funds, monies, assets
or other consideration being used to make the purchase and assumption hereunder
are "plan assets" as defined under ERISA and that its rights, benefits and
interests in and under the Loan Documents will not be "plan assets" under ERISA,
[and (vii) attaches the forms prescribed by the Internal Revenue Service of the
United States certifying that the Assignee is entitled to receive payments under
the Loan Documents without deduction or withholding of any United States federal
income taxes].

**TO BE INSERTED IF THE ASSIGNEE IS NOT INCORPORATED UNDER THE LAWS OF THE
UNITED STATES, OR A STATE THEREOF.

8.   INDEMNITY. The Assignee agrees to indemnify and hold the Assignor harmless
against any and all losses, costs and expenses (including, without limitation,
reasonable attorneys' fees) and liabilities incurred by the Assignor in
connection with or arising in any manner from the Assignee's non-performance of
the obligations assumed under this Assignment Agreement.

9.   SUBSEQUENT ASSIGNMENTS. After the Effective Date, the Assignee shall have
the right pursuant to SECTION 13.3.1 of the Credit Agreement to assign the
rights which are assigned to the Assignee hereunder to any entity or person,
provided that (i) any such subsequent assignment does not violate any of the
terms and conditions of the Loan Documents or any law, rule, regulation, order,
writ, judgment, injunction or decree and that any consent required under the
terms of the Loan Documents has been obtained and (ii) unless the prior written
consent of the Assignor is obtained, the Assignee is not thereby released from
its obligations to the Assignor hereunder, if any remain unsatisfied, including,
without limitation, its obligations under SECTIONS 4, 5 AND 8 hereof.

Commitment occurs between the date of this Assignment Agreement and the

From:  [NAME OF ASSIGNOR] (the "Assignor")

       [NAME OF ASSIGNEE] (the "Assignee")

       1. We refer to that Credit Agreement (the "Credit Agreement") described
in Item 1 of Schedule 1 attached hereto ("Schedule 1"). Capitalized terms used
herein and not otherwise defined herein shall have the meanings attributed to
them in the Credit Agreement.

This Notice of Assignment (this "Notice") is given and delivered to the
Administrative Agent pursuant to SECTION 13.3.2 of the Credit Agreement.

The Assignor and the Assignee have entered into an Assignment Agreement, dated
as of _________, ___ (the "Assignment"), pursuant to which, among other things,
the Assignor has sold, assigned, delegated and transferred to the Assignee, and
the Assignee has purchased, accepted and assumed from the Assignor the
percentage interest specified in Item 3 of Schedule 1 of all outstandings,
rights and obligations under the Credit Agreement. The Effective Date of the
Assignment shall be the later of the date specified in Item 5 of Schedule 1 or
two (2) Business Days (or such shorter period as agreed to by the Administrative
Agent) after this Notice of Assignment and any fee required by SECTION 13.3.2 of
the Credit Agreement have been delivered to the Administrative Agent, provided
that the Effective Date shall not occur if any condition precedent agreed to by
the Assignor and the Assignee has not been satisfied.

The Assignor and the Assignee hereby give to the Administrative Agent notice of
the assignment and delegation referred to herein. The Assignor will confer with
the Administrative Agent before the date specified in Item 5 of Schedule 1 to
determine if the Assignment Agreement will become effective on such date
pursuant to SECTION 3 hereof, and will confer with the Administrative Agent to
determine the Effective Date pursuant to SECTION 3 hereof if it occurs
thereafter. The Assignor shall notify the Administrative Agent if the Assignment
Agreement does not become effective on any proposed Effective Date as a result
of the failure to satisfy the conditions precedent agreed to by the Assignor and
the Assignee. At the request of the Administrative Agent, the Assignor will give
the Administrative Agent written confirmation of the satisfaction of the
conditions precedent.

The Assignor or the Assignee shall pay to the Administrative Agent on or before
the Effective Date the processing fee of $3,000 required by SECTION 13.3.2 of
the Credit Agreement.

If Notes are outstanding on the Effective Date, the Assignor and the Assignee
request and direct that the Administrative Agent prepare and cause the Borrower
to execute and deliver new Notes or, as appropriate, replacements notes, to the
Assignor and the Assignee. The Assignor and, if applicable, the

<PAGE>


Assignee each agree to deliver to the Administrative Agent the original Note
received by it from the Borrower upon its receipt of a new Note in the
appropriate amount.

The Assignee advises the Administrative Agent that notice and payment
instructions are set forth in the attachment to Schedule 1.

                           FORM OF SUBSIDIARY GUARANTY

       This Guaranty is made as of ________________, _____ by _________________,
a ________________ ("GUARANTOR"), to and for the benefit of The First National
Bank of Chicago, individually ("FIRST CHICAGO") and as administrative agent
("ADMINISTRATIVE AGENT") for itself and the lenders under the Credit Agreement
(as defined below) and their respective successors and assigns (collectively,
the "LENDERS").

                                    RECITALS

         A. Duke-Weeks Realty Limited Partnership, an Indiana limited
partnership ("BORROWER"), Duke-Weeks Realty Corporation, an Indiana corporation
(the "General Partner"), Banc One Capital Markets, Inc. ("BOCM") and Wachovia
Securities, Inc. ("Wachovia") (collectively, the "Lead Arrangers" and "Joint
Book Runners"), Wells Fargo Bank, National Association ("Wells Fargo") (the
"Co-Arranger"), First Chicago, individually, and as Administrative Agent, and
the Lenders have entered into a Revolving Credit Agreement dated as of July __,
1999 (as amended, modified or restated from time to time, the "CREDIT
AGREEMENT") pursuant to which the Lenders have agreed to provide Borrower with a
revolving credit facility in an aggregate principal amount of up to $300,000,000
(the "Facility"). All capitalized terms used herein and not otherwise defined
shall have the meanings ascribed to such terms in the Credit Agreement.

         B. Borrower has executed and delivered or will execute and deliver to
the Lenders promissory notes in the principal amount of each Lender's Commitment
as evidence of Borrower's indebtedness to each such Lender with respect to the
Facility (the promissory notes described above, together with any amendments or
allonges thereto, or restatements, replacements or renewals thereof, and/or new
promissory notes to new Lenders under the Credit Agreement, are collectively
referred to herein as the "NOTES").

         C. Guarantor is a Subsidiary of Borrower. Guarantor acknowledges that
the extension of credit by the Administrative Agent and the Lenders to Borrower
pursuant to the Credit Agreement will benefit Guarantor by making funds
available to Guarantor through Borrower and by enhancing the financial strength
of the consolidated group of which Guarantor and Borrower are members.

         D. SECTION 7.28 of the Credit Agreement permits Borrower to cause any
of its Subsidiaries to execute and deliver a Subsidiary Guaranty to the
Administrative Agent. After such execution and delivery, such Subsidiary's
Projects will no longer be excluded from the definition of "Unencumbered Assets"
solely because such Projects are directly owned by a Subsidiary. The execution
and delivery of this Guaranty by Guarantor is made pursuant to such
SECTION 7.28.

                                   AGREEMENTS

         NOW, THEREFORE, Guarantor, in consideration of the matters described in
the foregoing Recitals, which Recitals are incorporated herein and made a part
hereof, and for other good and valuable consideration, hereby agrees as follows:

         1. Guarantor absolutely, unconditionally, and irrevocably guarantees to
each of the Lenders:

            (a) the full and prompt payment of the principal of and interest on
     the Notes when due, whether at stated maturity, upon acceleration or
     otherwise, and at all times thereafter, and the prompt payment of all sums
     which may now be or may hereafter become due and owing under the Notes, the
     Credit Agreement, and the other Loan Documents;

            (b) the payment of all Enforcement Costs (as hereinafter defined in
     PARAGRAPH 7 hereof); and

            (c) the full, complete, and punctual observance, performance, and
     satisfaction of all of the obligations, duties, covenants, and agreements
     of Borrower under the Credit Agreement and the Loan Documents.

All amounts due, debts, liabilities, and payment obligations described in
subparagraphs (a) and (b) of this PARAGRAPH 1 are referred to herein as the
"FACILITY INDEBTEDNESS." All obligations described in subparagraph (c) of this
PARAGRAPH 1 are referred to herein as the "OBLIGATIONS." Guarantor and Lenders
agree that Guarantor's obligations hereunder shall not exceed the greater of:
(i) the aggregate amount of all monies received, directly or indirectly, by
Guarantor from Borrower after the date hereof (whether by loan, capital infusion
or other means), or (ii) the maximum amount of the Facility Indebtedness not
subject to avoidance under Title 11 of the United States Code, as same may be
amended from time to time, or any applicable state law (the "Bankruptcy Code").
To that end, to the extent such obligations would otherwise be subject to
avoidance under the Bankruptcy Code if Guarantor is not deemed to have received
valuable consideration, fair value or reasonably equivalent value for its
obligations hereunder, Guarantor's obligations hereunder shall be reduced to
that amount which, after giving effect thereto, would not render Guarantor
insolvent, or leave Guarantor with an unreasonably small capital to conduct its
business, or cause Guarantor to have incurred debts (or intended to have
incurred debts) beyond its ability to pay such debts as they mature, as such
terms are determined, and at the time such obligations are deemed to have been
incurred, under the Bankruptcy Code. In the event Guarantor shall make any
payment or payments under this Guaranty each other guarantor of the Facility
Indebtedness shall contribute to Guarantor an amount equal to such non-paying
guarantor's pro rata share (based on their respective maximum liabilities
hereunder and under such other guaranty) of such payment or payments made by
Guarantor, provided that such contribution right shall be subordinate and junior
in right of payment in full of all the Facility Indebtedness to Lenders.

         2. In the event of any default by Borrower in making payment of the
Facility Indebtedness, or in performance of the Obligations, as aforesaid, in
each case beyond the expiration of any applicable grace period, Guarantor
agrees, on demand by the Administrative Agent or the holder of a Note, to pay
all the Facility Indebtedness and to perform all the Obligations as are then or
thereafter

<PAGE>


become due and owing or are to be performed under the terms of the Notes, the
Credit Agreement, and the other Loan Documents.

         3. Guarantor does hereby waive (i) notice of acceptance of this
Guaranty by the Administrative Agent and the Lenders and any and all notices and
demands of every kind which may be required to be given by any statute, rule or
law, (ii) any defense, right of set-off or other claim which Guarantor may have
against Borrower or which Guarantor or Borrower may have against the
Administrative Agent or the Lenders or the holder of a Note, (iii) presentment
for payment, demand for payment (other than as provided for in PARAGRAPH 2
above), notice of nonpayment (other than as provided for in PARAGRAPH 2 above)
or dishonor, protest and notice of protest, diligence in collection and any and
all formalities which otherwise might be legally required to charge Guarantor
with liability, (iv) any failure by the Administrative Agent and the Lenders to
inform Guarantor of any facts the Administrative Agent and the Lenders may now
or hereafter know about Borrower, the Facility, or the transactions contemplated
by the Credit Agreement, it being understood and agreed that the Administrative
Agent and the Lenders have no duty so to inform and that Guarantor is fully
responsible for being and remaining informed by Borrower of all circumstances
bearing on the existence or creation, or the risk of nonpayment of the Facility
Indebtedness or the risk of nonperformance of the Obligations, and (v) any and
all right to cause a marshalling of assets of Borrower or any other action by
any court or governmental body with respect thereto, or to cause the
Administrative Agent and the Lenders to proceed against any other security given
to a Lender in connection with the Facility Indebtedness or the Obligations.
Credit may be granted or continued from time to time by the Lenders to Borrower
without notice to or authorization from Guarantor, regardless of the financial
or other condition of Borrower at the time of any such grant or continuation.
The Administrative Agent and the Lenders shall have no obligation to disclose or
discuss with Guarantor their assessment of the financial condition of Borrower.
Guarantor acknowledges that no representations of any kind whatsoever have been
made by the Administrative Agent and the Lenders to Guarantor. No modification
or waiver of any of the provisions of this Guaranty shall be binding upon the
Administrative Agent and the Lenders except as expressly set forth in a writing
duly signed and delivered on behalf of the Administrative Agent and the Lenders.
Guarantor further agrees that any exculpatory language contained in the Credit
Agreement, the Notes, and the other Loan Documents shall in no event apply to
this Guaranty, and will not prevent the Administrative Agent and the Lenders
from proceeding against Guarantor to enforce this Guaranty.

         4. Guarantor further agrees that Guarantor's liability as guarantor
shall in no way be impaired by any renewals or extensions which may be made from
time to time, with or without the knowledge or consent of Guarantor of the time
for payment of interest or principal under a Note or by any forbearance or delay
in collecting interest or principal under a Note, or by any waiver by the
Administrative Agent and the Lenders under the Credit Agreement, or any other
Loan Documents, or by the Administrative Agent or the Lenders' failure or
election not to pursue any other remedies they may have against Borrower, or by
any change or modification in a Note, the Credit Agreement, or any other Loan
Documents, or by the acceptance by the Administrative Agent or the Lenders of
any security or any increase, substitution or change therein, or by the release
by the Administrative Agent and the Lenders of any security or any withdrawal
thereof or decrease therein, or by the application of payments received from any
source to the payment of any obligation other than the Facility Indebtedness,
even though a Lender might lawfully have


<PAGE>


elected to apply such payments to any part or all of the Facility Indebtedness,
it being the intent hereof that Guarantor shall remain liable as principal for
payment of the Facility Indebtedness and performance of the Obligations until
all indebtedness has been paid in full and the other terms, covenants and
conditions of the Credit Agreement, and other Loan Documents and this Guaranty
have been performed, notwithstanding any act or thing which might otherwise
operate as a legal or equitable discharge of a surety. Guarantor further
understands and agrees that the Administrative Agent and the Lenders may at any
time enter into agreements with Borrower to amend and modify a Note, the Credit
Agreement or any of the other Loan Documents, or any thereof, and may waive or
release any provision or provisions of a Note, the Credit Agreement, or any
other Loan Document and, with reference to such instruments, may make and enter
into any such agreement or agreements as the Administrative Agent, the Lenders
and Borrower may deem proper and desirable, without in any manner impairing this
Guaranty or any of the Administrative Agent and the Lenders' rights hereunder or
any of Guarantor's obligations hereunder.

         5. This is an absolute, unconditional, complete, present and continuing
guaranty of payment and performance and not of collection. Guarantor agrees that
its obligations hereunder shall be joint and several with any and all other
guarantees given in connection with the Facility from time to time. Guarantor
agrees that this Guaranty may be enforced by the Administrative Agent and the
Lenders without the necessity at any time of resorting to or exhausting any
security or collateral, if any, given in connection herewith or with a Note, the
Credit Agreement, or any of the other Loan Documents or by or resorting to any
other guaranties, and Guarantor hereby waives the right to require the
Administrative Agent and the Lenders to join Borrower in any action brought
hereunder or to commence any action against or obtain any judgment against
Borrower or to pursue any other remedy or enforce any other right. Guarantor
further agrees that nothing contained herein or otherwise shall prevent the
Administrative Agent and the Lenders from pursuing concurrently or successively
all rights and remedies available to them at law and/or in equity or under a
Note, the Credit Agreement or any other Loan Documents, and the exercise of any
of their rights or the completion of any of their remedies shall not constitute
a discharge of any of Guarantor's obligations hereunder, it being the purpose
and intent of Guarantor that the obligations of such Guarantor hereunder shall
be primary, absolute, independent and unconditional under any and all
circumstances whatsoever. Neither Guarantor's obligations under this Guaranty
nor any remedy for the enforcement thereof shall be impaired, modified, changed
or released in any manner whatsoever by any impairment, modification, change,
release or limitation of the liability of Borrower under a Note, the Credit
Agreement or any other Loan Document or by reason of Borrower's bankruptcy or by
reason of any creditor or bankruptcy proceeding instituted by or against
Borrower. This Guaranty shall continue to be effective and be deemed to have
continued in existence or be reinstated (as the case may be) if at any time
payment of all or any part of any sum payable pursuant to a Note, the Credit
Agreement or any other Loan Document is rescinded or otherwise required to be
returned by the payee upon the insolvency, bankruptcy, or reorganization of the
payor, all as though such payment to such Lender had not been made, regardless
of whether such Lender contested the order requiring the return of such payment.
The obligations of Guarantor pursuant to the preceding sentence shall survive
any termination, cancellation, or release of this Guaranty.


<PAGE>


         6. This Guaranty shall be assignable by a Lender to any assignee of all
or a portion of such Lender's rights under the Loan Documents.

         7. If: (i) this Guaranty, a Note, or any of the Loan Documents are
placed in the hands of an attorney for collection or is collected through any
legal proceeding; (ii) an attorney is retained to represent the Administrative
Agent or any Lender in any bankruptcy, reorganization, receivership, or other
proceedings affecting creditors' rights and involving a claim under this
Guaranty, a Note, the Credit Agreement, or any Loan Document; (iii) an attorney
is retained to enforce any of the other Loan Documents or to provide advice or
other representation with respect to the Loan Documents in connection with an
enforcement action or potential enforcement action; or (iv) an attorney is
retained to represent the Administrative Agent or any Lender in any other legal
proceedings whatsoever in connection with this Guaranty, a Note, the Credit
Agreement, any of the Loan Documents, or any property subject thereto (other
than any action or proceeding brought by any Lender or participant against the
Administrative Agent alleging a breach by the Administrative Agent of its duties
under the Loan Documents), then Guarantor shall pay to the Administrative Agent
or such Lender upon demand all reasonable attorney's fees, costs and expenses,
including, without limitation, court costs, filing fees and all other costs and
expenses incurred in connection therewith (all of which are referred to herein
as "ENFORCEMENT COSTS"), in addition to all other amounts due hereunder.

         8. The parties hereto intend that each provision in this Guaranty
comports with all applicable local, state and federal laws and judicial
decisions. However, if any provision or provisions, or if any portion of any
provision or provisions, in this Guaranty is found by a court of law to be in
violation of any applicable local, state or federal ordinance, statute, law,
administrative or judicial decision, or public policy, and if such court should
declare such portion, provision or provisions of this Guaranty to be illegal,
invalid, unlawful, void or unenforceable as written, then it is the intent of
all parties hereto that such portion, provision or provisions shall be given
force to the fullest possible extent that they are legal, valid and enforceable,
that the remainder of this Guaranty shall be construed as if such illegal,
invalid, unlawful, void or unenforceable portion, provision or provisions were
not contained therein, and that the rights, obligations and interest of the
Administrative Agent and the Lender or the holder of a Note under the remainder
of this Guaranty shall continue in full force and effect.

         9. Any indebtedness of Borrower to Guarantor now or hereafter existing
is hereby subordinated to the Facility Indebtedness. Guarantor will not seek,
accept, or retain for Guarantor's own account, any payment from Borrower on
account of such subordinated debt at any time when a Default or Event of Default
exists under the Credit Agreement or the Loan Documents, and any such payments
to Guarantor made while any Default or Event of Default then exists under the
Credit Agreement or the Loan Documents on account of such subordinated debt
shall be collected and received by Guarantor in trust for the Lenders and shall
be paid over to the Administrative Agent on behalf of the Lenders on account of
the Facility Indebtedness without impairing or releasing the obligations of
Guarantor hereunder.

         10. Guarantor hereby subordinates to the Facility Indebtedness any and
all claims and rights, including, without limitation, subrogation rights,
contribution rights, reimbursement rights and set-off rights, which Guarantor
may have against Borrower arising from a payment made by

<PAGE>


Guarantor under this Guaranty and agrees that, until the entire Facility
Indebtedness is paid in full, not to assert or take advantage of any subrogation
rights of Guarantor or the Lenders or any right of Guarantor or the Lenders to
proceed against (i) Borrower for reimbursement, or (ii) any other guarantor or
any collateral security or guaranty or right of offset held by the Lenders for
the payment of the Facility Indebtedness and performance of the Obligations, nor
shall Guarantor seek or be entitled to seek any contribution or reimbursement
from Borrower or any other guarantor in respect of payments made by Guarantor
hereunder. It is expressly understood that the agreements of Guarantor set forth
above constitute additional and cumulative benefits given to the Lenders for
their security and as an inducement for their extension of credit to Borrower.

         11. Any amounts received by a Lender from any source on account of any
indebtedness may be applied by such Lender toward the payment of such
indebtedness, and in such order of application, as a Lender may from time to
time elect.

         12. Guarantor hereby submits to personal jurisdiction in the State of
Illinois for the enforcement of this Guaranty and waives any and all personal
rights to object to such jurisdiction for the purposes of litigation to enforce
this Guaranty. Guarantor hereby consents to the jurisdiction of either the
Circuit Court of Cook County, Illinois, or the United States District Court for
the Northern District of Illinois, in any action, suit, or proceeding which the
Administrative Agent or a Lender may at any time wish to file in connection with
this Guaranty or any related matter. Guarantor hereby agrees that an action,
suit, or proceeding to enforce this Guaranty may be brought in any state or
federal court in the State of Illinois and hereby waives any objection which
Guarantor may have to the laying of the venue of any such action, suit, or
proceeding in any such court; provided, however, that the provisions of this
Paragraph shall not be deemed to preclude the Administrative Agent or a Lender
from filing any such action, suit, or proceeding in any other appropriate forum.

         13. All notices and other communications provided to any party hereto
under this Agreement or any other Loan Document shall be in writing or by telex
or by facsimile and addressed or delivered to such party at its address set
forth below or at such other address as may be designated by such party in a
notice to the other parties. Any notice, if mailed and properly addressed with
