pursuant to Article 2 on the same date, all of which Loans are of the same type

Loans, have the same initial Interest Period. Borrowings are classified for
purposes of this Agreement either by reference to the pricing of Loans
comprising such Borrowing (E.G., a "FIXED RATE BORROWING" is a Euro-Dollar
Borrowing or a Money Market Borrowing (excluding any such Borrowing consisting
of Money Market LIBOR Loans bearing interest at the Base Rate pursuant to
Article VIII), and a "EURO-DOLLAR BORROWING" is a Borrowing comprised of
Euro-Dollar Loans) or by reference to the provisions of Article 2 under which
participation therein is determined (I.E., a "COMMITTED BORROWING" is a
Borrowing under Section 2.1 in which all Banks participate in proportion to
their Commitments, while a "MONEY MARKET BORROWING" is a Borrowing under Section
2.3 in which a Bank's share is determined on the basis of its bid in accordance
therewith, and a "Swingline Borrowing" is a Borrowing under Section 2.18 in
which only the Swingline Lender participates (subject to the provisions of said
Section 2.18)).

                                   THE CREDITS

         SECTION 2.1 COMMITMENTS TO LEND. Each Bank severally agrees, on the
terms and conditions set forth in this Agreement, to make Loans to the Borrower
and participate in Letters of Credit issued by the Fronting Bank on behalf of
the Borrower pursuant to this Article from time to time during the term hereof
in amounts such that the aggregate principal amount of Committed Loans plus such
Bank's Pro Rata Share of Swingline Loans by such Bank at any one time
outstanding together with such Bank's pro rata share of the Letter of Credit
Usage shall not exceed the amount of its Commitment. Each Borrowing outstanding
under this Section 2.1 shall be in an aggregate principal amount of $3,000,000,
or an integral multiple of $100,000 in excess thereof (except that any such
Borrowing may be in the aggregate amount available in accordance with Section
3.2(b), or in any amount required to reimburse the Fronting Bank for any drawing
under any Letter of Credit or to repay the Swingline Lender the amount of any
Swingline Loan) and, other than with respect to Money Market Loans and Swingline
Loans, shall be made from the several Banks ratably in proportion to their
respective Commitments. In no event shall the aggregate Loans outstanding at any
time, plus outstanding Letter of Credit Usage, exceed $700,000,000. Subject to
the limitations set forth herein, any amounts repaid may be reborrowed.

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

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

         (b)   Borrower shall give the Administrative Agent, and the designated
Fronting Bank, written notice in the event that it desires to have Letters of
Credit (each, a "LETTER OF CREDIT") issued, or to have Letters of Credit issued
on behalf of a Subsidiary, hereunder no later than 10:00 a.m., Chicago time, at
least four (4) Domestic Business Days prior to the date of such issuance. Each

and (viii) the terms upon which each such Letter of Credit may be drawn down
(which terms shall not leave any discretion to Fronting Bank). Each such notice
may be revoked telephonically by the Borrower to the applicable Fronting Bank
and the Administrative Agent any time prior to the date of issuance of the
Letter of Credit by the applicable Fronting Bank, provided such revocation is
confirmed in writing by the Borrower to the Fronting Bank and the Administrative
Agent within one (1) Domestic Business Day by facsimile. Notwithstanding
anything contained herein to the contrary, the Borrower shall complete and
deliver to the Fronting Bank any required documentation in connection with any
requested Letter of Credit no later than two (2) Domestic Business Days prior to
the issuance thereof. No later than 10:00 a.m., Chicago time, on the date that
is four (4) Domestic Business Days prior to the date of issuance, the Borrower
shall specify a precise description of the documents and the verbatim text of
any certificate to be presented by the beneficiary of such Letter of Credit,
which if presented by such beneficiary prior to the expiration date of the
Letter of Credit

                                       28

<PAGE>

would require the Fronting Bank to make a payment under the Letter of Credit;
PROVIDED, that Fronting Bank may, in its reasonable judgment, require changes in
any such documents and certificates only in conformity with changes in customary
and commercially reasonable practice or law and, PROVIDED FURTHER, that no
Letter of Credit shall require payment against a conforming draft to be made
thereunder on the third Domestic Business Day following the date that such draft
is presented if such presentation is made later than 10:00 A.M. Chicago time
(except that if the beneficiary of any Letter of Credit requests at the time of
the issuance of its Letter of Credit that payment be made on the same Domestic
Business Day against a conforming draft, such beneficiary shall be entitled to
such a same day draw, provided such draft is presented to the applicable
Fronting Bank no later than 10:00 A.M. Chicago time and provided further the
Borrower shall have requested to the Fronting Bank and the Administrative Agent
that such beneficiary shall be entitled to a same day draw). In determining
whether to pay on such Letter of Credit, the Fronting Bank shall be responsible
only to determine that the documents and certificates required to be delivered
under the Letter of Credit have been delivered and that they comply on their
face with the requirements of that Letter of Credit.

Administrative Agent unless such subsequent Money Market Quote is submitted
solely to correct a manifest error in such former Money Market Quote or modifies
the terms of such previous Money Market Quote to provide terms more favorable to
Borrower. The Administrative Agent's notice to the Borrower shall specify (A)
the aggregate principal amount of Money Market Loans for which offers have been
received for each Interest Period specified in the related Money Market Quote
Request, (B) the respective principal amounts and Money Market Margins or Money
Market Absolute Rates, as the case may be, so offered and (C) if applicable,
limitations on the aggregate principal amount of Money Market Loans for which
offers in any single Money Market Quote may be accepted.

         (f)   ACCEPTANCE AND NOTICE BY BORROWER. Not later than 10:30 A.M.
(Chicago time) on (x) the third Euro-Dollar Business Day prior to the proposed
date of Borrowing, in the case of a LIBOR Auction or (y) the proposed date of
Borrowing, in the case of an Absolute Rate Auction (or, in either case, such
other time or date as the Borrower and the Administrative Agent shall have
mutually agreed and shall have notified to the Banks not later than the date of
the Money Market Quote Request for the first LIBOR Auction or

                                       32

<PAGE>

Absolute Rate Auction for which such change is to be effective), the Borrower
shall notify the Administrative Agent of its acceptance or non-acceptance of the
offers so notified to it pursuant to subsection (e). In the case of acceptance,
such notice (a "NOTICE OF MONEY MARKET BORROWING") shall specify the aggregate
principal amount of offers for each Interest Period that are accepted. The
Borrower may accept any Money Market Quote in whole or in part; PROVIDED that:

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

         2.    the principal amount of each Money Market Borrowing must be
    $3,000,000 or a larger multiple of $100,000;

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

         4.    the Borrower may not accept any offer that is described in
    subsection (d)(3) or that otherwise fails to comply with the requirements of
    this Agreement.

         (g)   ALLOCATION BY AGENT. If offers are made by two or more Banks with
the same Money Market Margins or Money Market Absolute Rates, as the case may
be, for a greater aggregate principal amount than the amount in respect of which
such offers are accepted for the related Interest Period, the principal amount
of Money Market Loans in respect of which such offers are accepted shall be
allocated by the Administrative Agent among such Banks as nearly as possible (in
multiples of $100,000, as the Administrative Agent may deem appropriate) in
proportion to the aggregate principal amounts of such offers. The Administrative
Agent shall promptly (and in any event within one (1) Domestic Business Day
after such offers are accepted) notify the Borrower and each such Bank in
writing of any such allocation of Money Market Loans. Determinations by the
Administrative Agent of the allocation of Money Market Loans shall be conclusive
in the absence of manifest error.

         (h)   NOTIFICATION BY ADMINISTRATIVE AGENT. Upon receipt of the
Borrower's Notice of Money Market Borrowing in accordance with Section 2.3(f)
hereof, the Administrative Agent shall, on the date such Notice of Money Market
Borrowing is received by the Administrative Agent, promptly notify each Bank
(and such Notice of Money Market Borrowing shall not thereafter be revocable by
the Borrower) (i) of the principal amount of the Money Market Borrowing accepted
by the Borrower, and (ii) of such Bank's share (if any) of such Money Market
Borrowing. A Bank who is notified that it has been selected to make a Money
Market Loan may designate its Designated Lender (if any) to fund such Money

                                       33

<PAGE>

Market Loan on its behalf, as described in Section 9.6(d). Any Designated Lender
which funds a Money Market Loan shall on and after the time of such funding
become the obligee under such Money Market Loan and be entitled to receive
payment thereof when due. No Bank shall be relieved of its obligation to fund a
Money Market Loan, and no Designated Lender shall assume such obligation, prior
to the time the applicable Money Market Loan is funded.

         (i)   Notwithstanding anything to the contrary contained herein, each
Bank shall be required to fund its pro rata share of Committed Loans in
accordance with Section 2.1 hereof despite the fact that any Bank's Commitment
may have been or may be exceeded as a result of such Bank's making of Money
Market Loans.

         SECTION 2.4 NOTICE TO BANKS; FUNDING OF LOANS

         (a)   Upon receipt of a notice from Borrower in accordance with Section
2.2 hereof (each such notice being a "NOTICE OF BORROWING"), the Administrative
Agent shall, on the date such Notice of Borrowing is received by the
Administrative Agent, promptly notify each Bank of the contents thereof and of
such Bank's share of such Borrowing, of the interest rate determined pursuant
thereto and the Interest Period(s) (if different from those requested by the
Borrower) and such Notice of Borrowing shall not thereafter be revocable by the
Borrower, unless Borrower shall pay any applicable expenses pursuant to Section
2.13.

         (b)   Not later than 1:00 p.m. (Chicago time) on the date of each
Borrowing as indicated in the Notice of Borrowing, each Bank shall (except as
provided in subsection (c) of this Section) make available its share of such
Borrowing in Federal funds immediately available in Chicago, to the
Administrative Agent at its address referred to in Section 9.1. If the Borrower
has requested the issuance of a Letter of Credit, no later than 12:00 Noon
(Chicago time) on the date of such issuance as indicated in the notice delivered
pursuant to Section 2.2(b), the Fronting Bank shall issue such Letter of Credit
in the amount so requested and deliver the same to the Borrower with a copy
thereof to the Administrative Agent. Immediately upon the issuance of each
Letter of Credit by the Fronting Bank, such Fronting Bank shall be deemed to
have sold and transferred to each other Bank, and each such other Bank shall be
deemed, and hereby agrees, to have irrevocably and unconditionally purchased and
received from the Fronting Bank, without recourse or warranty, an undivided
interest and a participation in such Letter of Credit, any drawing thereunder,
and the obligations of the Borrower hereunder with respect thereto, and any
security therefor or guaranty pertaining thereto, in an amount equal to such
Bank's ratable share thereof (based upon the ratio its Commitment bears to the
aggregate of all Commitments). Upon any change in any of the Commitments in
accordance herewith, there shall be an automatic adjustment to such
participations to

                                       34

<PAGE>

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

         (c)   Not later than 3:00 p.m. (Chicago time) on the date of each
Swingline Borrowing as indicated in the applicable Notice of Borrowing, the
Swingline Lender shall make available such Swingline Borrowing in Federal funds
immediately available in Chicago, Illinois, to the Administrative Agent at its
address referred to herein.

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

         SECTION 2.5 NOTES.

         (a)   The Loans of each Bank shall be evidenced by a single Note
payable to the order of such Bank for the account of its Applicable Lending
Office.

         (b)   Each Bank may, by notice to the Borrower and the Administrative
Agent, request that its Loans of a particular type (including Swingline Loans
and Money Market Loans) be evidenced by a separate Note in an amount equal to
the aggregate unpaid principal amount of such Loans. Any additional costs
incurred by

                                       35

<PAGE>

the Administrative Agent, the Borrower or the Banks in connection with preparing
such a Note shall be at the sole cost and expense of the Bank requesting such
Note. In the event any Loans evidenced by such a Note are paid in full prior to
the Maturity Date, any such Bank shall return such Note to Borrower. Each such
Note shall be in substantially the form of EXHIBIT A hereto with appropriate
modifications to reflect the fact that it evidences solely Loans of the relevant
type. Upon the execution and delivery of any such Note, any existing Note
payable to such Bank shall be replaced or modified accordingly. Each reference
in this Agreement to the "NOTE" of such Bank shall be deemed to refer to and
include any or all of such Notes, as the context may require.

         (c)   Upon receipt of each Bank's Note pursuant to Section 3.1(a), the
Administrative Agent shall forward such Note to such Bank. Each Bank shall
record the date, amount, type and maturity of each Loan made by it and the date
and amount of each payment of principal made by the Borrower with respect
thereto, and may, if such Bank so elects in connection with any transfer or
enforcement of its Note, endorse on the appropriate schedule appropriate
notations to evidence the foregoing information with respect to each such Loan
then outstanding; PROVIDED that the failure of any Bank to make any such
recordation or endorsement shall not affect the obligations of the Borrower
hereunder or under the Notes. Each Bank is hereby irrevocably authorized by the
Borrower so to endorse its Note and to attach to and make a part of its Note a
continuation of any such schedule as and when required.

         (d)   The Committed Loans shall mature, and the principal amount
thereof shall be due and payable, on the Maturity Date. The Swingline Loans
shall mature, and the principal amount thereof shall be due and payable, in
accordance with Section 2.18(b)(iii).

         (e)   Each Money Market Loan included in any Money Market Borrowing
shall mature, and the principal amount thereof shall be due and payable,
together with accrued interest thereon, on the earlier to occur of (i) last day
of the Interest Period applicable to such Borrowing or (ii) the Maturity Date.

         (f)   There shall be no more than ten (10) Euro-Dollar Groups of Loans
outstanding at any one time.

         SECTION 2.6 METHOD OF ELECTING INTEREST RATES.

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

                                       36

<PAGE>

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

         (ii)  if such Loans are Euro-Dollar Loans, the Borrower may elect to
convert all or any portion of such Loans to Base Rate Loans and/or elect to
continue all or any portion of such Loans as Euro-Dollar Loans for an additional
Interest Period or additional Interest Periods, in each case effective on the
last day of the then current Interest Period applicable to such Loans, or on
such other date designated by Borrower in the Notice of Interest Rate Election
provided Borrower shall pay any losses pursuant to Section 2.13.

Each such election shall be made by delivering a notice (a "NOTICE OF INTEREST
RATE ELECTION") to the Administrative Agent at least three (3) Euro-Dollar
Business Days before the conversion or continuation selected in such notice is
to be effective. A Notice of Interest Rate Election may, if it so specifies,
apply to only a portion of the aggregate principal amount of the relevant Group
of Loans; PROVIDED that (i) such portion is allocated ratably among the Loans
comprising such Group, (ii) the portion to which such Notice applies, and the
remaining portion to which it does not apply, are each $500,000 or any larger
multiple of $100,000, (iii) there shall be no more than ten (10) Euro-Dollar
Groups of Loans outstanding at any time, (iv) no Committed Loan may be continued
as, or converted into, a Euro-Dollar Loan when any Event of Default has occurred
and is continuing, and (v) no Interest Period shall extend beyond the Maturity
Date.

         (b)   Each Notice of Interest Rate Election shall specify:

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

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

         (iii) if the Loans comprising such Group are to be converted, the new
type of Loans and, if such new Loans are Euro-Dollar Loans, the duration of the
initial Interest Period applicable thereto; and

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

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

                                       37

<PAGE>

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

         (d)   If the Borrower shall fail to pay any principal of or interest on
any Money Market Loan when due, such Money Market Loan shall bear interest,
payable on demand, for each day until paid at a rate per annum equal to the Base
Rate until such failure shall become an Event of Default and thereafter at a
rate per annum equal to the sum of 4% plus the Base Rate for such day.

         SECTION 2.7 INTEREST RATES.

         (a)   Each Base Rate Loan shall bear interest on the outstanding
principal amount thereof, for each day from the date such Loan is made until the
date it is repaid or converted into a Euro-Dollar Loan pursuant to Section 2.6
or at the Maturity Date, at a rate per annum equal to the Base Rate plus the
Applicable Margin for Base Rate Loans for such day. Such interest shall be
payable on the first Domestic Business Day of each month.

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

         The "ADJUSTED LONDON INTERBANK OFFERED RATE" applicable to any Interest
Period means the rate per annum, rounded upward, if necessary, to the nearest
1/100 of one percent, determined by the following formula:

                          LONDON INTERBANK OFFERED RATE
                     (1.00 - Euro-Dollar Reserve Percentage)

All figures used in this calculation shall be determined by the Administrative
Agent as of the first day of the applicable Interest Period, which must be a
Euro-Dollar Business Day.

         The "LONDON INTERBANK OFFERED RATE" applicable to any Interest Period
means the per annum rate of interest, rounded upward, if necessary, to the
nearest 1/16th of one percent (0.0625%), at which the Euro-Dollar Reference
Bank's London

                                       38

<PAGE>

Branch, London, England, would offer U.S. dollar deposits for the applicable
Interest Period to other major banks in the London interbank market at
approximately 11:00 a.m. (London time) two Euro-Dollar Business Days before the
first day of such Interest Period in an amount approximately equal to the
principal amount of the Euro-Dollar Borrowing or Group Of Loans or portion
thereof to be converted into or continued as Euro-Dollar Loans to which such
Interest Period is to apply.

         "EURO-DOLLAR RESERVE PERCENTAGE" means the total of the maximum reserve
percentages for determining the reserves to be maintained by member banks of the
Federal Reserve System for Eurocurrency Liabilities, as defined in Regulation D,
as Regulation D may be amended, modified or supplemented. The Euro-Dollar
Reserve Percentage shall be expressed in decimal form and rounded upward, if
necessary, to the nearest 1/100th of one percent, and shall include marginal,
emergency, supplemental, special and other reserve percentages. The Adjusted
London Interbank Offered Rate shall be adjusted automatically on and as of the
effective date of any change in the Euro-Dollar Reserve Percentage.

         (c)   Subject to Section 8.1, each Money Market LIBOR Loan shall bear
interest on the outstanding principal amount thereof, for the Interest Period
applicable thereto, at a rate per annum equal to the sum of the London Interbank
Offered Rate for such Interest Period (determined in accordance with Section
2.7(b) as if the related Money Market LIBOR Borrowing were a Euro-Dollar
Borrowing) plus (or minus) the Money Market Margin quoted by the Bank making
such Loan in accordance with Section 2.3. Each Money Market Absolute Rate Loan
shall bear interest on the outstanding principal amount thereof, for the
Interest Period applicable thereto, at a rate per annum equal to the Money
Market Absolute Rate quoted by the Bank making such Loan in accordance with
Section 2.3. Such interest shall be payable for each Interest Period on the last
day thereof and, if such Interest Period is longer than one month, at intervals
of one month after the first day thereof. Any overdue principal of or interest
on any Money Market Loan shall bear interest, payable on demand, for each day
until paid at a rate per annum equal to the Base Rate until such failure shall
become an Event of Default and thereafter at a rate per annum equal to the sum
of 4% plus the Base Rate for such day.

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

         (e)   The Administrative Agent shall determine each interest rate
applicable to the Loans hereunder. The Administrative Agent shall give prompt
notice to the Borrower and

                                       39

<PAGE>

the Banks of each rate of interest so determined, and its determination thereof
shall be conclusive in the absence of demonstrable error.

         (f)   The Euro-Dollar Reference Bank agrees to use its best efforts to
furnish quotations to the Administrative Agent as contemplated by this Section.

         SECTION 2.8 FEES.

         (a)   FACILITY FEE. The Borrower shall pay to the Administrative Agent
for the account of the Banks ratably in proportion to their respective
Commitments a facility fee (the "FACILITY FEE") on the aggregate Commitments at
the respective percentages per annum based upon the range into which the
Borrower's Credit Rating then falls, in accordance with the following table. The
facility fee shall be payable in arrears on each January 1, April 1, July 1 and
October 1 during the Term.

<TABLE>
<CAPTION>
                  <S>                       <C>
                  Less than BBB-/
                           Baa3             0.300%
                  BBB-/Baa3                 0.250%
                  BBB/Baa2                  0.200%
                  BBB+/Baa1                 0.200%
                  A-/A3                     0.175%
                  A/A2 or better            0.150%

</TABLE>

Any change in the Borrower's Credit Rating causing it to move into a different
range on the table shall effect an immediate change in the applicable percentage
per annum. In the event that the Borrower receives two (2) Credit Ratings and
such ratings are split between a higher and a lower range on the table, the
applicable percentage per annum shall be based upon the lower of such two (2)
Credit Ratings. In the event that Borrower receives more than two (2) Credit
Ratings, and such ratings are not equivalent, the applicable percentage per
annum shall be determined by the lower of the two (2) highest ratings, provided
that each of said two (2) highest ratings shall be Investment Grade Ratings and
at least one of which shall be an Investment Grade Rating from S&P or Moody's.
In the event that each of said two (2) highest ratings shall not be Investment
Grade Ratings or at least one shall not be an Investment Grade Rating from S&P
or Moody's, then the applicable percentage per annum shall be determined by the
lowest of the ratings. In the event that only one (1) Rating Agency has set the
Borrower's Credit Rating, then the applicable percentage per annum shall be
based on such single rating.

         (b)   LETTER OF CREDIT FEE. During the Term, the Borrower shall pay to
the Administrative Agent, for the account of the Banks in proportion to their
interests in respect of issued and undrawn Letters of Credit, a fee (a "LETTER
OF CREDIT FEE") in an amount, provided that no Event of Default shall have
occurred and be continuing, equal to a rate per annum equal to

                                       40

<PAGE>

the then percentage per annum of the Applicable Margin with respect to
Euro-Dollar Loans, on the daily average of such issued and undrawn Letters of
Credit, which fee shall be payable, in arrears, on each January 1, April 1, July
1 and October 1 during the Term. From the occurrence, and during the
continuance, of an Event of Default, such fee shall be increased to be equal to
four percent (4%) per annum on the daily average of such issued and undrawn
Letters of Credit.

         (c)   FRONTING BANK FEE. The Borrower shall pay any Fronting Bank, for
its own account, a fee (a "FRONTING BANK FEE") at a rate per annum equal to .10%
of the issued and undrawn amount of such Letter of Credit, which fee shall be in
addition to and not in lieu of, the Letter of Credit Fee. The Fronting Bank Fee
shall be payable in arrears on each January 1, April 1, July 1 and October 1
during the Term.

         (d)   FEES NON-REFUNDABLE. All fees set forth in this Section 2.8 shall
be deemed to have been earned on the date payment is due in accordance with the
provisions hereof and shall be non-refundable. The obligation of the Borrower to
pay such fees in accordance with the provisions hereof shall be binding upon the
Borrower and shall inure to the benefit of the Administrative Agent and the
Banks regardless of whether any Loans are actually made.

         SECTION 2.9 MATURITY DATE.

         The term (the "TERM") of the Commitments (and each Bank's obligations
to make Loans and to participate in Letters of Credit hereunder) shall terminate
and expire, and the Borrower shall return or cause there to be returned all
Letters of Credit to the Fronting Bank, on the Maturity Date. Upon the date of
the termination of the Term, any Loans then outstanding (together with accrued
interest thereon and all other Obligations) shall be due and payable on such
date.

         SECTION 2.10 MANDATORY PREPAYMENTS.

         (a)   If at any time the Borrower, EQR or any Consolidated Subsidiary
of either or both sells, transfers, assigns or conveys any Real Property Asset
which shall cause the Borrower in any fiscal year period commencing after the
Closing Date, to have sold, transferred or conveyed property or assets which
constitute in the aggregate more than 30% of the Gross Asset Value of the
Borrower, EQR and any Consolidated Subsidiary of either or both on the date of
such transfer, then at the request of Administrative Agent, Borrower shall pay
to the Administrative Agent, for the account of the Banks, within thirty (30)
days after the date of such request, an amount equal to the Net Proceeds of such
transfer (but in no event more than the outstanding balance of the Loans).
Borrower shall make such prepayment together with interest accrued to the date
of the prepayment on the principal amount prepaid. In connection with

                                       41

<PAGE>

the prepayment of a Euro-Dollar Loan prior to the maturity thereof, the
Borrower shall also pay any applicable expenses pursuant to Section 2.13.
Each such prepayment shall be applied to prepay ratably the Loans of the
Banks. Amounts prepaid pursuant to this Section 2.10(a) may not be
reborrowed. As used in this Section 2.10, the term "NET PROCEEDS" shall mean
all amounts received by Borrower, EQR and the Consolidated Subsidiaries of
either or both in connection with such sale, transfer, assignment or
conveyance after payment of all expenses to be made by Borrower and any
Consolidated Subsidiaries in connection with such sale, transfer, assignment
or conveyance (including, without limitation, payment of then existing Liens
or encumbrances on such Real Property Asset, brokerage commissions, title and
survey costs or transfer taxes).

         (b)   If at any time the Borrower or EQR, directly or indirectly shall
purchase or hold any interest in any Investment Affiliates which, taken singly
or in the aggregate, exceeds fifteen percent (15%) of the Gross Asset Value of
the Borrower, EQR and the Consolidated Subsidiaries of either or both then, at
the request of Administrative Agent, Borrower shall pay to the Administrative
Agent, for the account of the Banks, within thirty (30) days after the date of
such request, an amount equal to the outstanding balance of all Borrowings
hereunder (except as to any Fixed Rate Borrowings for which such repayments
shall be made at the end of the Interest Period applicable to such Fixed Rate
Borrowing), and Borrower shall not be entitled to request any further Borrowings
under this Agreement until such time as the interest in any Investment
Affiliates of Borrower or EQR (directly or indirectly) shall not, taken singly
or in the aggregate, exceed fifteen percent (15%) of the Gross Asset Value of
the Borrower, EQR and the Consolidated Subsidiaries of either or both. Borrower
shall make such prepayment together with interest accrued to the date of the
prepayment on the principal amount prepaid. Amounts prepaid pursuant to this
Section 2.10(b) may be reborrowed in accordance with the provisions of this
Agreement.

         SECTION 2.11 OPTIONAL PREPAYMENTS.

         (a)   The Borrower may, upon at least one (1) Domestic Business Day's
notice to the Administrative Agent, prepay any Group of Base Rate Loans (or any
Money Market Borrowing bearing interest at the Base Rate pursuant to Section
8.1), in whole at any time, or from time to time in part in amounts aggregating
One Million Dollars ($1,000,000) or any larger multiple of One Hundred Thousand
Dollars ($100,000), by paying the principal amount to be prepaid. The Borrower
may, from time to time on any Domestic Business Day so long as prior notice is
given to the Administrative Agent and Swingline Lender no later than 1:00 p.m.
(Chicago time) on the day on which Borrower intends to make such prepayment,
prepay any Swingline Loans in whole or in part in amounts aggregating $100,000
or a higher integral multiple of $100,000 (or, if less, the aggregate
outstanding principal amount

                                       42

<PAGE>

of all Swingline Loans then outstanding) by paying the principal amount to be
prepaid no later than 2:00 p.m. (Chicago time) on such day. Each such optional
prepayment shall be applied to prepay ratably the Loans of the several Banks
included in such Group of Loans or Borrowing(or the Swingline Lender in the case
of Swingline Loans) included in such Group or Borrowing.

         (b)   The Borrower may, upon at least one (1) Euro-Dollar Business
Days' notice to the Administrative Agent, prepay any Euro-Dollar Loan as of the
last day of the Interest Period applicable thereto. Except as provided in
Article 8 and except with respect to any Euro-Dollar Loan which has been
converted to a Base Rate Loan pursuant to Section 8.2, 8.3 or 8.4 hereof, the
Borrower may not prepay all or any portion of the principal amount of any
Euro-Dollar Loan prior to the end of the Interest Period applicable thereto
unless the Borrower shall also pay any applicable expenses pursuant to Section
2.13. Any such prepayment shall be upon at least three (3) Euro-Dollar Business
Days notice to the Administrative Agent. Each such optional prepayment shall be
in the amounts set forth in Section 2.11(a) above and shall be applied to prepay
ratably the Loans of the Banks included in any Group of Euro-Dollar Loans,
except that any Euro-Dollar Loan which has been converted to a Base Rate Loan
pursuant to Section 8.2, 8.3 or 8.4 hereof may be prepaid without ratable
payment of the other Loans in such Group of Loans which have not been so
converted.

         (c)   The Borrower may, upon at least one (1) Domestic Business Day's
notice to the Administrative Agent (by 11:00 a.m Chicago time on such Domestic
Business Day), reimburse the Administrative Agent for the benefit of the
Fronting Bank for the amount of any drawing under a Letter of Credit in whole or
in part in any amount.

         (d)   The Borrower may at any time return any undrawn Letter of Credit
to the Fronting Bank in whole, but not in part, and the Fronting Bank within a
reasonable period of time shall give the Administrative Agent and each of the
Banks notice of such return.

         (e)   The Borrower may at any time and from time to time cancel all or
any part of the Commitments by the delivery to the Administrative Agent of a
notice of cancellation within the applicable time periods set forth in Sections
2.11(a) and (b) if there are Loans then outstanding or, if there are no Loans
outstanding at such time as to which the Commitments with respect thereto are
being cancelled, upon at least one (1) Domestic Business Day's notice to the
Administrative Agent, whereupon, in either event, all or such portion of the
Commitments, as applicable, shall terminate as to the Banks, pro rata on the
date set forth in such notice of cancellation, and, if there are any Loans then
outstanding, Borrower shall prepay, as applicable, all or such portion of Loans
outstanding on such date in accordance with the requirements of Section 2.11(a)
and (b). In no event

                                       43

<PAGE>

shall the Borrower be permitted to cancel Commitments for which a Letter of
Credit has been issued and is outstanding unless the Borrower returns (or causes
to be returned) such Letter of Credit to the Fronting Bank. Borrower shall be
permitted to designate in its notice of cancellation which Loans, if any, are to
be prepaid. A reduction of the Commitments pursuant to this Section 2.11(c)
shall not effect a reduction in the Swingline Commitment (unless so elected by
the Borrower) until the aggregate Commitments have been reduced to an amount
equal to the Swingline Commitment.

         (f)   Any amounts so prepaid pursuant to Section 2.11 (a), (b), (c) or
(d) may be reborrowed. In the event Borrower elects to cancel all or any portion
of the Commitments and the Swingline Commitment pursuant to Section 2.11(e)
hereof, such amounts may not be reborrowed.

         (g)   The Borrower may not prepay any portion of a Money Market Loan
except with the prior consent of the Bank or Designated Lender holding such
Money Market Loan.

         SECTION 2.12 GENERAL PROVISIONS AS TO PAYMENTS.

         (a)   The Borrower shall make each payment of interest on the Loans and
of fees hereunder, not later than 12:00 Noon (Chicago time) on the date when
due, in Federal or other funds immediately available in Chicago, to the
Administrative Agent at its address referred to in Section 9.1. The
Administrative Agent will promptly (and if received prior to 12:00 noon, on the
same Domestic Business Day, if received after 12:00 noon on the immediately
following Domestic Business Day) distribute to each Bank its ratable share (or
applicable share with respect to Money Market Loans) of each such payment
received by the Administrative Agent for the account of the Banks. If and to the
extent that the Administrative Agent shall receive any such payment for the
account of the Banks on or before 12:00 Noon (Chicago time) on any Domestic
Business Day, and Administrative Agent shall not have distributed to any Bank
its applicable share of such payment on such Domestic Business Day,
Administrative Agent shall distribute such amount to such Bank together with
interest thereon, for each day from the date such amount should have been
distributed to such Bank until the date Administrative Agent distributes such
amount to such Bank, at the Federal Funds Rate. Whenever any payment of

                                       44

<PAGE>

principal of, or interest on the Base Rate Loans or Swingline Loans or of fees
shall be due on a day which is not a Domestic Business Day, the date for payment
thereof shall be extended to the next succeeding Domestic Business Day. Whenever
any payment of principal of, or interest on, the Euro-Dollar Loans shall be due
on a day which is not a Euro-Dollar Business Day, the date for payment thereof
shall be extended to the next succeeding Euro-Dollar Business Day unless such
Euro-Dollar Business Day falls in another calendar month, in which case the date
for payment thereof shall be the next preceding Euro-Dollar Business Day.
Whenever any payment of principal of, or interest on, the Money Market Loans
shall be due on a day which is not a Euro-Dollar Business Day, the date for
payment thereof shall be extended to the next succeeding Euro-Dollar Business
Day. If the date for any payment of principal is extended by operation of law or
otherwise, interest thereon shall be payable for such extended time.

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

         SECTION 2.13 FUNDING LOSSES. If the Borrower makes any payment of
principal with respect to any Euro-Dollar Loan or Money Market LIBOR Loan
(pursuant to Article II, VI or VIII or otherwise) on any day other than the last
day of the Interest Period applicable thereto, or if the Borrower fails to
borrow any Euro-Dollar Loans or Money Market LIBOR Loans after notice has been
given to any Bank in accordance with Section 2.4(a), or if Borrower shall
deliver a Notice of Interest Rate Election specifying that a Euro-Dollar Loan
shall be converted on a date other than the first (lst) day of the then current
Interest Period applicable thereto, the Borrower shall reimburse each Bank
within 15 days after certification of such Bank of such loss or expense (which
shall be delivered by each such Bank to Administrative Agent for delivery to
Borrower) for any resulting loss or expense incurred by it (or by an existing
Participant in the related Loan), including (without limitation) any loss
incurred in obtaining, liquidating or employing deposits from third parties, but
excluding loss of margin for the period after any such payment or failure to
borrow, PROVIDED that such Bank shall have delivered to Administrative Agent and
Administrative Agent shall have delivered to the Borrower a certification as to
the amount of such loss or expense, which certification shall set forth in
reasonable detail the basis for and calculation of such loss or expense and
shall be conclusive in the absence of demonstrable error.

         SECTION 2.14 COMPUTATION OF INTEREST AND FEES. All interest and fees
shall be computed on the basis of a year of 360 days and paid for the actual
number of days elapsed (including the first day but excluding the last day).

                                       45

<PAGE>

         SECTION 2.15 USE OF PROCEEDSOF PROCEEDS. The Borrower shall use the
proceeds of the Loans for general corporate purposes, including, without
limitation, the acquisition of real property to be used in the Borrower's
existing business and for general working capital needs of the Borrower;
provided, however, that no Swingline Loan shall be used more than once for the
purpose of refinancing another Swingline Loan, in whole or part.

         SECTION 2.16 LETTERS OF CREDIT.

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

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

         (c)   The Letter of Credit Usage shall be no more than Two Hundred
Million Dollars ($200,000,000) at any one time.

         (d)   There shall be no more than twenty (20) Letters of Credit
outstanding at any one time.

         (e)   In the event of any request for a drawing under any Letter of
Credit by the beneficiary thereunder, the Fronting Bank shall notify the
Borrower and the Administrative Agent (and the Administrative Agent shall notify
each Bank thereof) on or before the date on which the Fronting Bank intends to
honor such drawing, and, except as provided in this subsection (e), the Borrower
shall reimburse the Fronting Bank, in immediately available funds, on the same
day on which such drawing is honored in an amount equal to the amount of such
drawing. Notwithstanding anything contained herein to the contrary, however,
unless the Borrower shall have notified the Administrative Agent, and the
Fronting Bank prior to 11:00 a.m. (Chicago time) on the Domestic Business Day
immediately prior to the date of such drawing that the Borrower intends to
reimburse the Fronting Bank for the amount of such drawing with funds other than
the proceeds of the Loans, the Borrower shall be deemed to have timely given a
Notice of Borrowing pursuant to Section 2.2 to the Administrative Agent,
requesting a Borrowing of Base Rate Loans on the date on which such drawing is
honored and in an amount equal to the amount of such drawing. Each Bank (other
than the Fronting Bank) shall, in accordance with Section 2.3(b), make available
its pro rata share of such Borrowing to the Administrative Agent, the proceeds
of which shall be applied directly by the Administrative Agent to reimburse the
Fronting Bank for the amount of such draw. In the event that any such Bank fails
to make available to the Fronting Bank the amount of

                                       46

<PAGE>

such Bank's participation on the date of a drawing, the Fronting Bank shall be
entitled to recover such amount on demand from such Bank together with interest
at the Federal Funds Rate commencing on the date such drawing is honored, and
the provisions of Section 9.16 shall otherwise apply to such failure.

         (f)   If, after the date hereof, any change in any law or regulation or
in the interpretation thereof by any court or administrative or governmental
authority charged with the administration thereof shall either (i) impose,
modify or deem applicable any reserve, special deposit or similar requirement
against letters of credit issued by, or assets held by, or deposits in or for
the account of, or participations in any letter of credit, upon any Bank
(including the Fronting Bank) or (ii) impose on any Bank any other condition
regarding this Agreement or such Bank (including the Fronting Bank) as it
pertains to the Letters of Credit or any participation therein and the result of
any event referred to in the preceding clause (i) or (ii) shall be to increase,
by an amount deemed by the Fronting Bank or such Bank to be material, the cost
to the Fronting Bank or any Bank of issuing or maintaining any Letter of Credit
or participating therein, then the Borrower shall pay to the Fronting Bank or
such Bank, within 15 days after written demand by such Bank (with a copy to the
Administrative Agent), which demand shall be accompanied by a certificate
showing, in reasonable detail, the calculation of such amount or amounts, such
additional amounts as shall be required to compensate the Fronting Bank or such
Bank for such increased costs or reduction in amounts received or receivable
hereunder. Each Bank will promptly notify the Borrower and the Administrative
Agent of any event of which it has knowledge, occurring after the date hereof,
which will entitle such Bank to compensation pursuant to this Section 2.16 and
will designate a different Applicable Lending Office if such designation will
avoid the need for, or reduce the amount of, such compensation and will not, in
the reasonable judgment of such Bank, be otherwise disadvantageous to such Bank.
If such Bank shall fail to notify Borrower of any such event within 90 days
following the end of the month during which such event occurred, then Borrower's
liability for any amounts described in this Section incurred by such Bank as a
result of such event shall be limited to those attributable to the period
occurring subsequent to the ninetieth (90th) day prior to the date upon which
such Bank actually notified Borrower of the occurrence of such event. A
certificate of any Bank claiming compensation under this Section 2.16 and
setting forth a reasonably detailed calculation of the additional amount or
amounts to be paid to it hereunder shall be conclusive in the absence of
demonstrable error. In determining such amount, such Bank may use any reasonable
averaging and attribution methods.

         (g)   The Borrower hereby agrees to protect, indemnify, pay and save
the Fronting Bank harmless from and against any and all claims, demands,
liabilities, damages, losses, costs, charges and expenses (including reasonable
attorneys' fees and

                                       47

<PAGE>

disbursements) which the Fronting Bank may incur or be subject to as a result of
(i) the issuance of the Letters of Credit, other than to the extent of the bad
faith, gross negligence or wilful misconduct of the Fronting Bank or (ii) the
failure of the Fronting Bank to honor a drawing under any Letter of Credit as a
result of any act or omission, whether rightful or wrongful, of any present or
future DE JURE or DE FACTO government or governmental authority (collectively,
"GOVERNMENTAL ACTS"), other than to the extent of the bad faith, gross
negligence or wilful misconduct of the Fronting Bank. As between the Borrower
and the Fronting Bank, the Borrower assumes all risks of the acts and omissions
of any beneficiary with respect to its use, or misuses of, the Letters of Credit
issued by the Fronting Bank. In furtherance and not in limitation of the
foregoing, the Fronting Bank shall not be responsible (i) for the form,
validity, sufficiency, accuracy, genuineness or legal effect of any document
submitted by any party in connection with the application for and issuance of
such Letters of Credit, even if it should in fact prove to be in any or all
respects invalid, insufficient, inaccurate, fraudulent or forged; (ii) for the
validity or insufficiency of any instrument transferring or assigning or
purporting to transfer or assign any such Letter of Credit or the rights or
benefits thereunder or proceeds thereof, in whole or in part, which may prove to
be invalid or ineffective for any reason; (iii) for failure of the beneficiary
of any such Letter of Credit to comply fully with conditions required in order
to draw upon such Letter of Credit, other than as a result of the bad faith,
gross negligence or wilful misconduct of the Fronting Bank; (iv) for errors,
omissions, interruptions or delays in transmission or delivery of any message,
by mail, cable, telegraph, facsimile transmission, or otherwise; (v) for errors
in interpretation of any technical terms; (vi) for any loss or delay in the
transmission or otherwise of any documents required in order to make a drawing
under any such Letter of Credit or of the proceeds thereof; (vii) for the
misapplication by the beneficiary of any such Letter of Credit of the proceeds
of such Letter of Credit; and (viii) for any consequence arising from causes
beyond the control of the Fronting Bank, including any Government Acts, in each
case other than to the extent of the bad faith, gross negligence or willful
misconduct of the Fronting Bank. None of the above shall affect, impair or
prevent the vesting of the Fronting Bank's rights and powers hereunder. In
furtherance and extension and not in limitation of the specific provisions
hereinabove set forth, any action taken or omitted by the Fronting Bank under or
in connection with the Letters of Credit issued by it or the related
certificates, if taken or omitted in good faith, shall not put the Fronting Bank
under any resulting liability to the Borrower; provided that, notwithstanding
anything in the foregoing to the contrary, the Fronting Bank will be liable to
the Borrower for any damages suffered by the Borrower or its Subsidiaries as a
result of the Fronting Bank's grossly negligent or wilful failure to pay under
any Letter of Credit after the presentation to it of a sight

                                       48

<PAGE>

draft and certificates strictly in compliance with the terms and conditions of
the Letter of Credit.

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

         SECTION 2.17 LETTER OF CREDIT USAGE ABSOLUTE. The obligations of the
Borrower under this Agreement in respect of any Letter of Credit shall be
unconditional and irrevocable, and shall be paid strictly in accordance with the
terms of this Agreement (as the same may be amended from time to time) and any
Letter of Credit Documents (as hereinafter defined) under all circumstances,
including, without limitation, to the extent permitted by law, the following
circumstances:

         (a)   any lack of validity or enforceability of any Letter of Credit or
any other agreement or instrument relating thereto (collectively, the "LETTER OF
CREDIT DOCUMENTS") or any Loan Document;

         (b)   any change in the time, manner or place of payment of, or in any
other term of, all or any of the obligations of the Borrower in respect of the
Letters of Credit or any other amendment or waiver of or any consent by the
Borrower to departure from all or any of the Letter of Credit Documents or any
Loan Document; PROVIDED, that the Fronting Bank shall not consent to any such
change or amendment unless previously consented to in writing by the Borrower;

         (c)   any exchange, release or non-perfection of any collateral, or any
release or amendment or waiver of or consent to departure from any guaranty, for
all or any of the obligations of the Borrower in respect of the Letters of
Credit;

         (d)   the existence of any claim, set-off, defense or other right that
the Borrower may have at any time against any beneficiary or any transferee of a
Letter of Credit (or any Persons for whom any such beneficiary or any such
transferee may be acting), the Administrative Agent, the Fronting Bank or any
Bank (other than a defense based on the bad faith, gross negligence or wilful
misconduct of the Administrative Agent, the Fronting Bank or such Bank) or any
other Person, whether in connection with the Loan Documents, the transactions
contemplated

                                       49

<PAGE>

hereby or by the Letters of Credit Documents or any unrelated transaction;

         (e)   any draft or any other document presented under or in connection
with any Letter of Credit or other Loan Document proving to be forged,
fraudulent, invalid or insufficient in any respect or any statement therein
being untrue or inaccurate in any respect; PROVIDED, that payment by the
Fronting Bank under such Letter of Credit against presentation of such draft or
document shall not have been the result of the bad faith, gross negligence or
wilful misconduct of the Fronting Bank;

         (f)   payment by the Fronting Bank against presentation of a draft or
certificate that does not strictly comply with the terms of the Letter of
Credit; PROVIDED, that such payment shall not have been the result of the bad
faith, gross negligence or wilful misconduct of the Fronting Bank; and

         (g)   any other circumstance or happening whatsoever other than the
payment in full of all obligations hereunder in respect of any Letter of Credit
or any agreement or instrument relating to any Letter of Credit, whether or not
similar to any of the foregoing, that might otherwise constitute a defense
available to, or a discharge of, the Borrower; PROVIDED, that such other
circumstance or happening shall not have been the result of bad faith, gross
negligence or wilful misconduct of the Fronting Bank.

         SECTION 2.18 SWINGLINE LOAN SUBFACILITY.

         (a)   SWINGLINE COMMITMENTCOMMITMENT. Subject to the terms and
conditions of this Section 2.18, the Swingline Lender, in its individual
capacity, agrees to make certain revolving credit loans to the Borrower (each a
"SWINGLINE LOAN" and, collectively, the "SWINGLINE LOANS") from time to time
during the term hereof; provided, however, that the aggregate amount of
Swingline Loans outstanding at any time shall not exceed the lesser of (i) FIFTY
MILLION DOLLARS ($50,000,000), and (ii) the aggregate Commitments less all Loans
then outstanding (the "SWINGLINE COMMITMENT"). Subject to the limitations set
forth herein, any amounts repaid in respect of Swingline Loans may be
reborrowed.

         (b)   SWINGLINE BORROWINGSBORROWINGS.

         (i)   NOTICE OF BORROWING. With respect to any Swingline Borrowing, the
Borrower shall give the Swingline Lender and the Administrative Agent notice in
writing which is received by the Swingline Lender and Administrative Agent not
later than 1:00 p.m. (Chicago time) on the proposed date of such Swingline
Borrowing (and confirmed by telephone by such time), specifying (A) that a
Swingline Borrowing is being requested, (B) the amount of such Swingline
Borrowing, (C) the proposed date of such Swingline Borrowing, which shall be a
Domestic Business Day and

                                       50
<PAGE>

(D) stating that no Default or Event of Default has occurred and is continuing
both before and after giving effect to such Swingline Borrowing. Such notice
shall be irrevocable.

         (ii)  MINIMUM AMOUNTS. Each Swingline Borrowing shall be in a minimum
principal amount of $1,000,000, or an integral multiple of $100,000 in excess
thereof.

         (iii) REPAYMENT OF SWINGLINE LOANS. Each Swingline Loan shall be due
and payable on the earliest of (A) 5 Domestic Business Days from the date of the
applicable Swingline Borrowing, (B) the date of the next Committed Borrowing or
(C) the Maturity Date. In addition, in no event shall Swingline Loans be
outstanding for more than ten (10) Domestic Business Days in any calendar month.
If, and to the extent, any Swingline Loans shall be outstanding on the date of
any Committed Borrowing, such Swingline Loans shall first be repaid from the
proceeds of such Committed Borrowing prior to the disbursement of the same to
the Borrower. If, and to the extent, a Committed Borrowing is not requested
prior to the Maturity Date or the end of the 5-Domestic Business Day period
after a Swingline Borrowing, the Borrower shall be deemed to have requested a
Committed Borrowing comprised entirely of Base Rate Loans in the amount of the
applicable Swingline Loan then outstanding, the proceeds of which shall be used
to repay such Swingline Loan to the Swingline Lender. In addition, the Swingline
Lender may, at any time, in its sole discretion, by written notice to the
Borrower and the Administrative Agent, demand repayment of its Swingline Loans
by way of a Committed Borrowing, in which case the Borrower shall be deemed to
have requested a Committed Borrowing comprised entirely of Base Rate Loans in
the amount of such Swingline Loans then outstanding, the proceeds of which shall
be used to repay such Swingline Loans to the Swingline Lender. Any Committed
Borrowing which is deemed requested by the Borrower in accordance with this
Section 2.18(b)(iii) is hereinafter referred to as a "Mandatory Borrowing". Each
Bank hereby irrevocably agrees to make Committed Loans promptly upon receipt of
notice from the Swingline Lender of any such deemed request for a Mandatory
Borrowing in the amount and in the manner specified in the preceding sentences
and on the date such notice is received by such Bank (or the next Domestic
Business Day if such notice is received after 12:00 P.M. (Chicago time))
notwithstanding (I) the amount of the Mandatory Borrowing may not comply with
the minimum amount of Committed Borrowings otherwise required hereunder, (II)
whether any conditions specified in Section 3.2 are then satisfied, (III)
whether a Default

                                       51

<PAGE>

or an Event of Default then exists, (IV) failure of any such deemed request for
a Committed Borrowing to be made by the time otherwise required in Section 2.1,
(V) the date of such Mandatory Borrowing (provided that such date must be a
Domestic Business Day), or (VI) any termination of the Commitments immediately
prior to such Mandatory Borrowing or contemporaneously therewith; provided,
however, that no Bank shall be obligated to make Committed Loans in respect of a
Mandatory Borrowing if a Default or an Event of Default then exists and the
applicable Swingline Loan was made by the Swingline Lender without receipt of a
written Notice of Borrowing in the form specified in subclause (i) above or
after Administrative Agent has delivered a notice of Default or Event of Default
which has not been rescinded.

         (iv)  PURCHASE OF PARTICIPATIONS. In the event that any Mandatory
Borrowing cannot for any reason be made on the date otherwise required above
(including, without limitation , as a result of the commencement of a proceeding
under the Bankruptcy Code with respect to the Borrower), then each Bank hereby
agrees that it shall forthwith, upon demand, purchase (as of the date the
Mandatory Borrowing would otherwise have occurred, but adjusted for any payment
received from the Borrower on or after such date and prior to such purchase)
from the Swingline Lender such participations in the outstanding Swingline Loans
as shall be necessary to cause each such Bank to share in such Swingline Loans
ratably based upon its Pro Rata Share (determined before giving effect to any
termination of the Commitments pursuant hereto), provided that (A) all interest
payable on the Swingline Loans with respect to any participation shall be for
the account of the Swingline Lender until but excluding the day upon which the
Mandatory Borrowing would otherwise have occurred, and (B) in the event of a
delay between the day upon which the Mandatory Borrowing would otherwise have
occurred and the time any purchase of a participation pursuant to this sentence
is actually made, the purchasing Bank shall be required to pay to the Swingline
Lender interest on the principal amount of such participation for each day from
and including the day upon which the Mandatory Borrowing would otherwise have
occurred to but excluding the date of payment for such participation, at the
rate equal to the Federal Funds Rate, for the two (2) Domestic Business Days
after the date the Mandatory Borrowing would otherwise have occurred, and
thereafter at a rate equal to the Base Rate. Notwithstanding the foregoing, no
Bank shall be obligated to purchase a participation in any Swingline Loan if a
Default or an Event of Default then exists and such Swingline Loan was made by
the Swingline Lender without receipt of a written Notice of Borrowing in the
form specified in subclause (i) above or after Administrative Agent has
delivered a notice of Default or Event of Default which has not been rescinded.

         (c)   INTEREST RATERATE. Each Swingline Loan shall bear interest on the
outstanding principal amount thereof, for each day from the date such Swingline
Loan is made until the date it is repaid, at a rate per annum equal to the
Federal Funds Rate for such day, plus the Applicable Margin for Euro-Dollar
Loans, plus .20%.

                                   ARTICLE IV

                         REPRESENTATIONS AND WARRANTIES

         In order to induce the Administrative Agent and each of the other Banks
which is or may become a party to this Agreement to make the Loans, the Borrower
makes the following representations and warranties as of the Closing Date. Such
representations and warranties shall survive the effectiveness of this
Agreement, the execution and delivery of the other Loan Documents and the making
of the Loans.

         SECTION 4.1 EXISTENCE AND POWER. The Borrower is a limited partnership,
duly formed and validly existing as a limited partnership under the laws of the
State of Illinois and has all powers and all material governmental licenses,
authorizations, consents and approvals required to own its property and assets
and carry on its business as now conducted or as it presently proposes to
conduct and has been duly qualified and is in good standing in every
jurisdiction in which the failure to be so qualified and/or in good standing is
likely to have a Material Adverse Effect. EQR is a real estate investment trust,
duly formed, validly existing and in good standing as a real estate investment
trust under the laws of the State of Maryland and has all powers and all
material governmental licenses, authorizations, consents and approvals required
to own its property and assets and carry on its business as now conducted or as
it presently proposes to conduct and has been duly qualified and is in good
standing in every jurisdiction in which the failure to be so qualified and/or in
good standing is likely to have a Material Adverse Effect.

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

                                       56

<PAGE>

         SECTION 4.3 NO VIOLATION. Neither the execution, delivery or
performance by or on behalf of the Borrower of the Loan Documents to which it is
a party, nor compliance by the Borrower with the terms and provisions thereof
nor the consummation of the transactions contemplated by the Loan Documents, (i)
will materially contravene any applicable provision of any law, statute, rule,
regulation, order, writ, injunction or decree of any court or governmental
instrumentality, (ii) will materially conflict with or result in any breach of,
any of the terms, covenants, conditions or provisions of, or constitute a
default under, or result in the creation or imposition of (or the obligation to
create or impose) any Lien upon any of the property or assets of the Borrower or
any of its Consolidated Subsidiaries pursuant to the terms of any indenture,
mortgage, deed of trust, or other agreement or other instrument to which the
Borrower (or of any partnership of which the Borrower is a partner) or any of
its Consolidated Subsidiaries is a party or by which it or any of its property
or assets is bound or to which it is subject, or (iii) will cause a material
default by the Borrower under any organizational document of any Person in which
the Borrower has an interest, or cause a material default under the Borrower's
agreement or certificate of limited partnership, the consequences of which
conflict, breach or default would have a Material Adverse Effect, or result in
or require the creation or imposition of any Lien whatsoever upon any Property
(except as contemplated herein).

         SECTION 4.4 FINANCIAL INFORMATION.

         (a)   The consolidated balance sheet of the Borrower and its
Consolidated Subsidiaries, dated as of December 31, 1998, and the related
consolidated statements of Borrower's financial position for the fiscal year
then ended, reported on by Ernst & Young LLP, a copy of which has been delivered
to each of the Banks, fairly present, in conformity with GAAP, the consolidated
financial position of the Borrower and its Consolidated Subsidiaries as of such
date and their consolidated results of operations and cash flows for such fiscal
year.

         (b)   The consolidated balance sheet of EQR, dated as of December 31,
1998, and the related consolidated statements of EQR's financial position for
the fiscal year then ended, reported on by Ernst & Young LLP and set forth in
the EQR 1998 Form 10-K, a copy of which has been delivered to each of the Banks,
fairly present, in conformity with GAAP, the consolidated financial position of
EQR and its Consolidated Subsidiaries as of such date and their consolidated
results of operations and cash flows for such fiscal year.

         (c)   Since March 31, 1999, (i) except as may have been disclosed in
writing to the Banks, nothing has occurred having a Material Adverse Effect, and
(ii) except as previously disclosed to the Banks, neither the Borrower nor EQR
has incurred any material indebtedness or guaranty on or before the Closing
Date.

                                       57

<PAGE>

         SECTION 4.5 LITIGATION. Except as previously disclosed by the Borrower
in writing to the Banks, there is no action, suit or proceeding pending against,
or to the knowledge of the Borrower threatened against or affecting, (i) the
Borrower, EQR or any of their Consolidated Subsidiaries, (ii) the Loan Documents
or any of the transactions contemplated by the Loan Documents or (iii) any of
their assets, before any court or arbitrator or any governmental body, agency or
official in which there is a reasonable possibility of an adverse decision which
could, individually, or in the aggregate have a Material Adverse Effect or which
in any manner draws into question the validity of this Agreement or the other
Loan Documents.

         SECTION 4.6 COMPLIANCE WITH ERISA.

         (a)   Except as set forth on SCHEDULE 4.6 attached hereto, neither
Borrower nor EQR is a member of any Plan or Multiemployer Plan or any other
Benefit Arrangement.

         (b)   The transactions contemplated by the Loan Documents will not
constitute a nonexempt prohibited transaction (as such term is defined in
Section 4975 of the Code or Section 406 of ERISA) that could subject the
Administrative Agent or the Banks to any tax or penalty or prohibited
transactions imposed under Section 4975 of the Code or Section 502(i) of ERISA.

         SECTION 4.7 ENVIRONMENTAL MATTERS. The Borrower and EQR each conducts
reviews of the effect of Environmental Laws on the business, operations and
properties of the Borrower, EQR and Consolidated Subsidiaries of either or both
when necessary in the course of which it identifies and evaluates associated
liabilities and costs (including, without limitation, any capital or operating
expenditures required for clean-up or closure of properties presently owned, any
capital or operating expenditures required to achieve or maintain compliance
with environmental protection standards imposed by law or as a condition of any
license, permit or contract, any related constraints on operating activities,
and any actual or potential liabilities to third parties, including employees,
and any related costs and expenses). On the basis of this review, the Borrower
and EQR each has reasonably concluded that such associated liabilities and
costs, including the costs of compliance with Environmental Laws, are unlikely
to have a Material Adverse Effect on the Borrower, EQR and their Consolidated
Subsidiaries.

         SECTION 4.8 TAXES. United States Federal income tax returns of the
Borrower, EQR and their Consolidated Subsidiaries have been prepared and filed
through the fiscal year ended December 31, 199 . The Borrower, EQR and their
Consolidated Subsidiaries have filed all United States Federal income tax
returns and all other material tax returns which are required to be filed by
them and have paid all taxes due pursuant to such returns or pursuant to any
assessment received by the Borrower,

                                       58

<PAGE>

EQR or any Consolidated Subsidiary, except such taxes, if any, as are reserved
against in accordance with GAAP, such taxes as are being contested in good faith
by appropriate proceedings or such taxes, the failure to make payment of which
when due and payable will not have, in the aggregate, a Material Adverse Effect.
The charges, accruals and reserves on the books of the Borrower, EQR and their
Consolidated Subsidiaries in respect of taxes or other governmental charges are,
in the opinion of the Borrower, adequate.

         SECTION 4.9 FULL DISCLOSURE. All information heretofore furnished by
the Borrower to the Administrative Agent or any Bank for purposes of or in
connection with this Agreement or any transaction contemplated hereby or thereby
is true and accurate in all material respects on the date as of which such
information is stated or certified. The Borrower has disclosed to the
Administrative Agent, in writing any and all facts which have or may have (to
the extent the Borrower can now reasonably foresee) a Material Adverse Effect.

         SECTION 4.10 SOLVENCY. On the Closing Date and after giving effect to
the transactions contemplated by the Loan Documents occurring on the Closing
Date, the Borrower will be Solvent.

         SECTION 4.11 USE OF PROCEEDS; MARGIN REGULATIONS. All proceeds of the
Loans will be used by the Borrower only in accordance with the provisions
hereof. No part of the proceeds of any Loan will be used by the Borrower to
purchase or carry any Margin Stock or to extend credit to others for the purpose
of purchasing or carrying any Margin Stock in any manner that might violate the
provisions of Regulations T, U or X of the Federal Reserve Board. Neither the
making of any Loan nor the use of the proceeds thereof will violate or be
inconsistent with the provisions of Regulations T, U or X of the Federal Reserve
Board.

         SECTION 4.12 GOVERNMENTAL APPROVALS. No order, consent, approval,
license, authorization, or validation of, or filing, recording or registration
with, or exemption by, any governmental or public body or authority, or any
subdivision thereof, is required to authorize, or is required in connection with
the execution, delivery and performance of any Loan Document or the consummation
of any of the transactions contemplated thereby other than those that have
already been duly made or obtained and remain in full force and effect or those
which, if not made or obtained, would not have a Material Adverse Effect;

         SECTION 4.13 INVESTMENT COMPANY ACT; PUBLIC UTILITY HOLDING COMPANY
ACT. Neither the Borrower, EQR nor any Consolidated Subsidiary is (x) an
"INVESTMENT COMPANY" or a company "CONTROLLED" by an "INVESTMENT COMPANY",
within the meaning of the Investment Company Act of 1940, as amended, (y) a
"HOLDING company" or a "SUBSIDIARY COMPANY" of a "HOLDING COMPANY" or an
"AFFILIATE" of either a "HOLDING COMPANY" or a

                                       59

<PAGE>

"SUBSIDIARY COMPANY" within the meaning of the Public Utility Holding Company
Act of 1935, as amended, or (z) subject to any other federal or state law or
regulation which purports to restrict or regulate its ability to borrow money.

         SECTION 4.14 PRINCIPAL OFFICES. As of the Closing Date, the principal
office, chief executive office and principal place of business of the Borrower
is Two North Riverside Plaza, Suite 400, Chicago, Illinois 60606.

EQR qualified and EQR intends to continue to qualify as a real estate investment
trust under the Code.

         SECTION 4.16 PATENTS, TRADEMARKS, ETC. The Borrower has obtained and
holds in full force and effect all patents, trademarks, servicemarks, trade
names, copyrights and other such rights, free from burdensome restrictions,
which are necessary for the operation of its business as presently conducted,
the impairment of which is likely to have a Material Adverse Effect.

         SECTION 4.17 OWNERSHIP OF PROPERTY. SCHEDULE 4.17 attached hereto and
made a part hereof sets forth all the real property owned or ground leased by
the Borrower, EQR and Persons in which the Borrower and/or EQR, directly or
indirectly, owns an interest as of the Closing Date. As of the Closing Date, the
Borrower, EQR and such Persons have good and insurable fee simple title (or
leasehold title if so designated on SCHEDULE 4.17) to all of such real property,
subject to Permitted Liens. As of the date of this Agreement, there are no
mortgages, deeds of trust, indentures, debt instruments or other agreements
creating a Lien against any of the Real Property Assets except as disclosed on
SCHEDULE 4.17.

         SECTION 4.18 NO DEFAULT. No Event of Default or, to the best of the
Borrower's knowledge, Default exists under or with respect to any Loan Document
and the Borrower is not in default in any material respect beyond any applicable
grace period under or with respect to any other material agreement, instrument
or undertaking to which it is a party or by which it or any of its property is
bound in any respect, the existence of which default is likely to result in a
Material Adverse Effect.

         SECTION 4.19 LICENSES, ETC. The Borrower has obtained and does hold in
full force and effect, all franchises, licenses, permits, certificates,
authorizations, qualifications, accreditation, easements, rights of way and
other consents and approvals which are necessary for the operation of its
businesses as presently conducted, the absence of which is likely to have a
Material Adverse Effect.

         SECTION 4.20 COMPLIANCE WITH LAW. To the Borrower's knowledge, the
Borrower and each of the Real Property Assets are in compliance with all laws,
rules, regulations, orders,

                                       60

<PAGE>

judgments, writs and decrees, including, without limitation, all building and
zoning ordinances and codes, the failure to comply with which is likely to have
a Material Adverse Effect.

         SECTION 4.21 NO BURDENSOME RESTRICTIONS. Except as may have been
disclosed by the Borrower in writing to the Banks, Borrower is not a party to
any agreement or instrument or subject to any other obligation or any charter or
corporate or partnership restriction, as the case may be, which, individually or
in the aggregate, is likely to have a Material Adverse Effect.

         SECTION 4.22 BROKERS' FEES. The Borrower has not dealt with any broker
or finder with respect to the transactions contemplated by this Agreement or
otherwise in connection with this Agreement, and the Borrower has not done any
act, had any negotiations or conversation, or made any agreements or promises
which will in any way create or give rise to any obligation or liability for the
payment by the Borrower of any brokerage fee, charge, commission or other
compensation to any party with respect to the transactions contemplated by the
Loan Documents, other than the fees payable to the Administrative Agent and the
Banks.

         SECTION 4.23 LABOR MATTERS. There are no collective bargaining
agreements or Multiemployer Plans covering the employees of the Borrower and the
Borrower has not suffered any strikes, walkouts, work stoppages or other
material labor difficulty within the last five years.

         SECTION 4.24 INSURANCE. The Borrower and/or EQR currently maintains
insurance at 100% replacement cost insurance coverage (subject to customary
deductibles) in respect of each of the Real Property Assets, as well as
commercial general liability insurance (including "builders' risk" where
applicable) against claims for personal, and bodily injury and/or death, to one
or more persons, or property damage, as well as workers' compensation insurance,
in each case with respect to liability and casualty insurance with insurers
having an A.M. Best policyholders' rating of not less than A-VII in amounts that
prudent owner of assets such as the Real Property Assets would maintain.

         SECTION 4.25 ORGANIZATIONAL DOCUMENTS. The documents delivered pursuant
to Section 3.1(f) constitute, as of the Closing Date, all of the organizational
documents (together with all amendments and modifications thereof) of the
Borrower and EQR. The Borrower represents that it has delivered to the
Administrative Agent true, correct and complete copies of each of the documents
set forth in this Section 4.25.

         SECTION 4.26 QUALIFYING UNENCUMBERED PROPERTIES. As of the date hereof,
each Property listed on EXHIBIT F as a Qualifying Unencumbered Property (i) is
an operating multifamily residential property wholly-owned (directly or
beneficially) by

                                       61

<PAGE>

Borrower and/or EQR or a wholly-owned Subsidiary of either or both, (ii) is not
subject (nor are any equity interests in such Property subject) to a Lien which
secures Indebtedness of any Person, other than Permitted Liens, (iii) is not
subject (nor are any equity interests in such Property subject) to any covenant,
condition, or other restriction which prohibits or limits the creation or
assumption of any Lien upon such Property (it being understood that covenants
similar to those set forth in Section 5.8 hereof shall not be deemed to
constitute any such prohibition or limitation), and (iv) is not owned by a
Subsidiary of the Borrower or EQR (other than the Borrower) that has any
outstanding Unsecured Debt (other than those items of Indebtedness set forth in
clauses (e), (f), (i) or (j) of the definition of Indebtedness, or any
Contingent Obligation other than guarantees for borrowed money). All of the
information set forth on EXHIBIT F is true and correct in all material respects.

         SECTION 4.27 YEAR 2000 COMPLIANCE. The Borrower and EQR have conducted
a review and assessment of the Borrower's and EQR's computer applications with
respect to the "year 2000 problem" (that is, the risk that computer applications
may not be able to properly perform date-sensitive functions after December 31,
1999) and, based on that review and inquiry, the Borrower does not believe that
the "year 2000 problem" will result in a Material Adverse Effect to the
Borrower's or EQR's financial condition or results of operations, or on its
ability to repay the Loans.

                                    ARTICLE V

                       AFFIRMATIVE AND NEGATIVE COVENANTS

         The Borrower covenants and agrees that, so long as any Bank has any
Commitment hereunder or any Obligations remain unpaid:

and their Consolidated Subsidiaries as of the end of such fiscal year and the

Borrower's or EQR's fiscal year ended at the end of such quarter, all reported
on in the form provided to the Securities and Exchange Commission on Borrower's
and EQR's Form 10Q, and (ii) and such other information reasonably requested by
the Administrative Agent or any Bank;

Borrower was in compliance with the requirements of Section 5.8 on the date of
such financial statements; (ii) certifying (x) that such financial statements
fairly present the financial condition and the results of operations of the
Borrower on the dates and for the periods indicated, on the basis of GAAP, with
respect to the Borrower subject, in the case of interim financial statements, to
normally recurring year-end adjustments, and (y) that such officer has reviewed
the terms of the Loan Documents and has made, or caused to be made under his or
her supervision, a review in reasonable detail of the business and condition of
the Borrower during the period beginning on the date through which the last such

certification pursuant to this Section 5.1(c), the Closing Date) and ending on a
date not more than ten (10) Domestic Business Days prior to the date of such
delivery and that (1) on the basis of such financial statements and such review

Consolidated Subsidiary to keep, all property useful and necessary in its
business, including without limitation the Real Property Assets (for so long as

maintained, insurance comparable to that described in Section 4.24 hereof with

Effect or expose Administrative Agent or the Banks to any material liability
therefor.

         SECTION 5.6 INSPECTION OF PROPERTY, BOOKS AND RECORDS. The Borrower and
EQR each will keep proper books of record and account in which full, true and
correct entries shall be made of all dealings and transactions in relation to

enable EQR to

                                       67

thereof (such market value to be determined in a manner reasonably acceptable to
Administrative Agent).

postpone compliance with the obligation being contested as long as (i) no Event
of Default shall have occurred and be continuing, (ii) EQR shall have given
Administrative Agent prior written notice of the commencement of such contest,

Subsidiary to any criminal penalty or subject Administrative Agent or any Bank

any Property material to Borrower or its condition or prospects shall be in
substantial danger of being sold, forfeited or lost, by

                                       71

indirectly convey, sell, transfer, assign, pledge or otherwise encumber or

(determined as of the date of occurrence of such Termination Event) of the
insufficiency of such Plan and the insufficiency of any and all other Plans with
respect to which such a Termination Event shall occur and be continuing (or, in
the case of a Multiple Employer Plan with respect to which a Termination Event
described in clause (ii) of the definition of Termination Event shall occur and
be continuing, the liability of the Borrower) is equal to or greater than
$10,000,000 and which the Administrative Agent reasonably determines will have a

         SECTION 6.2 RIGHTS AND REMEDIES.

         (a)   Upon the occurrence of any Event of Default described in Sections
6.1(f) or (g), the Commitments and the

                                       74

<PAGE>

Swingline Commitment shall immediately terminate and the unpaid principal amount
of, and any and all accrued interest on, the Loans and any and all accrued fees
and other Obligations hereunder shall automatically become immediately due and
payable, with all additional interest from time to time accrued thereon and
without presentation, demand, or protest or other requirements of any kind
(including, without limitation, valuation and appraisement, diligence,
presentment, notice of intent to demand or accelerate and notice of
acceleration), all of which are hereby expressly waived by the Borrower; and
upon the occurrence and during the continuance of any other Event of Default,
subject to the provisions of Section 6.2(b), the Administrative Agent may (and
upon the demand of the Required Banks shall), by written notice to the Borrower,
in addition to the exercise of all of the rights and remedies permitted the
Administrative Agent and the Banks at law or equity or under any of the other
Loan Documents, declare the Commitments terminated and the unpaid principal
amount of and any and all accrued and unpaid interest on the Loans and any and
all accrued fees and other Obligations hereunder to be, and the same shall
thereupon be, immediately due and payable with all additional interest from time
to time accrued thereon and (except as otherwise as provided in the Loan
Documents) without presentation, demand, or protest or other requirements of any
kind (including, without limitation, valuation and appraisement, diligence,
presentment, notice of intent to demand or accelerate and notice of
acceleration), all of which are hereby expressly waived by the Borrower.

         (b)   Notwithstanding anything to the contrary contained in this
Agreement or in any other Loan Document, the Lead Agent, and the Banks each
agree that any exercise or enforcement of the rights and remedies granted to the
Administrative Agent or the Banks under this Agreement or at law or in equity
with respect to this Agreement or any other Loan Documents shall be commenced
and maintained by the Administrative Agent on behalf of the Administrative Agent
and/or the Banks. The Administrative Agent shall act at the direction of the
Required Banks in connection with the exercise of any and all remedies at law,
in equity or under any of the Loan Documents (including, without limitation,
those set forth in Section 6.4 hereof) or, if the Required Banks are unable to
reach agreement, then, from and after an Event of Default, the Administrative
Agent may pursue such rights and remedies as it may determine.

         SECTION 6.3 NOTICE OF DEFAULT. The Administrative Agent shall give
notice to the Borrower under Section 6.1(c) promptly upon being requested to do
so by the Required Banks and shall thereupon notify all the Banks thereof. The
Administrative Agent shall not be deemed to have knowledge or notice of the
occurrence of any Default or Event of Default (other than nonpayment of
principal of or interest on the Loans) unless Administrative Agent has received
notice in writing from a Bank or Borrower or any court or governmental agency
referring to this Agreement or the other Loan Documents, describing such event
or

                                       75
<PAGE>

condition. Should Administrative Agent receive notice of the occurrence of an
Default or Event of Default expressly stating that such notice is a notice of an
Default or Event of Default, or should Administrative Agent send Borrower a
notice of Default or Event of Default, Administrative Agent shall promptly give
notice thereof to each Bank.

         SECTION 6.4 ACTIONS IN RESPECT OF LETTERS OF CREDIT.

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

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

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

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

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

                                       76

<PAGE>

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

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

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

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

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

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

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

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

                                       77

<PAGE>

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

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

         SECTION 6.5 DISTRIBUTION OF PROCEEDS AFTER DEFAULT. Notwithstanding
anything contained herein to the contrary, from and after an Event of Default,
to the extent proceeds are received by Administrative Agent, such proceeds will
be distributed to the Banks pro rata in accordance with the unpaid principal
amount of the Loans.

                                   ARTICLE VII

                                   THE AGENTS

         SECTION 7.1 APPOINTMENT AND AUTHORIZATION. Each Bank irrevocably
appoints and authorizes the Administrative Agent to take such action as agent on
its behalf and to exercise such powers under this Agreement and the other Loan
Documents as are delegated to the Administrative Agent by the terms hereof or
thereof, together with all such powers as are reasonably incidental thereto.
Except as set forth in Sections 7.8 and 7.9 hereof, the provisions of this
Article VII are solely for the benefit of Administrative Agent and the Banks,
and Borrower shall not have any rights to rely on or enforce any of the
provisions hereof. In performing its functions and duties under this Agreement,
Administrative Agent shall act solely as an agent of the Banks and does not
assume and shall not be deemed to have assumed any obligation toward or
relationship of agency or trust with or for the Borrower.

         SECTION 7.2 AGENCY AND AFFILIATES. Bank of America, National
Association shall have the same rights and powers under this Agreement as any
other Bank and may exercise or refrain from exercising the same as though it
were not the Administrative Agent, and Bank of America, National Association and
its affiliates may accept deposits from, lend money to, and generally engage in
any kind of business with the Borrower, EQR or any

                                       78

<PAGE>

Subsidiary or affiliate of the Borrower as if it was not the Administrative
Agent hereunder, and the term "Bank" and "Banks" shall include Bank of America,
National Association in its individual capacity.

         SECTION 7.3 ACTION BY ADMINISTRATIVE AGENT. The obligations of the
Administrative Agent hereunder are only those expressly set forth herein.
Without limiting the generality of the foregoing, the Administrative Agent shall
not be required to take any action with respect to any Default or Event of
Default, except as expressly provided in Article VI. The duties of
Administrative Agent shall be administrative in nature. Subject to the
provisions of Sections 7.1, 7.5 and 7.6, Administrative Agent shall administer
the Loans in the same manner as it administers its own loans.

         SECTION 7.4 CONSULTATION WITH EXPERTS. As between Administrative Agent
and the Banks, the Administrative Agent may consult with legal counsel (who may
be counsel for the Borrower), independent public accountants and other experts
selected by it and shall not be liable for any action taken or omitted to be
taken by it in good faith in accordance with the advice of such counsel,
accountants or experts.

         SECTION 7.5 LIABILITY OF ADMINISTRATIVE AGENT AND SYNDICATION AGENT. As
between Administrative Agent and the Banks, none of the Administrative Agent,
the Syndication Agent nor any of their affiliates nor any of their respective
directors, officers, agents or employees shall be liable for any action taken or
not taken by any of them in connection herewith (i) with the consent or at the
request of the Required Banks or (ii) in the absence of its own gross negligence
or wilful misconduct. As between Administrative Agent and the Banks, none of the
Administrative Agent, the Syndication Agent nor any of their respective
directors, officers, agents or employees shall be responsible for or have any
duty to ascertain, inquire into or verify (i) any statement, warranty or
representation made in connection with this Agreement or any borrowing
hereunder; (ii) the performance or observance of any of the covenants or
agreements of the Borrower, except with respect to payment of principal and
interest; (iii) the satisfaction of any condition specified in Article III,
except receipt of items required to be delivered to the Administrative Agent; or
(iv) the validity, effectiveness or genuineness of this Agreement, the other
Loan Documents or any other instrument or writing furnished in connection
herewith. As between Administrative Agent and the Banks, the Administrative
Agent shall not incur any liability by acting in reliance upon any notice,
consent, certificate, statement, or other writing (which may be a bank wire, or
similar writing) believed by it to be genuine or to be signed by the proper
party or parties.

         SECTION 7.6 INDEMNIFICATION. Each Bank shall, ratably in accordance
with its Commitment, indemnify the Administrative

                                       79

<PAGE>

Agent and the Syndication Agent and their respective affiliates and directors,
officers, agents and employees (to the extent not reimbursed by the Borrower)
against any cost, expense (including counsel fees and disbursements), claim,
demand, action, loss or liability (except such as result from such indemnitee's
gross negligence or wilful misconduct) that such indemnitee may suffer or incur
in connection with its duties as Administrative Agent and/or Syndication Agent
under this Agreement, the other Loan Documents or any action taken or omitted by
such indemnitee hereunder as Administrative Agent or as Syndication Agent. In
the event that the Syndication Agent or the Administrative Agent shall,
subsequent to its receipt of indemnification payment(s) from Banks in accordance
with this section, recoup any amount from the Borrower, or any other party
liable therefor in connection with such indemnification, such Syndication Agent
or the Administrative Agent shall reimburse the Banks which previously made the
payment(s) PRO RATA, based upon the actual amounts which were theretofore paid
by each Bank. The Syndication Agent or the Administrative Agent, as the case may
be, shall reimburse such Banks so entitled to reimbursement within two (2)
Domestic Business Days of its receipt of such funds from the Borrower or such
other party liable therefor.

         SECTION 7.7 CREDIT DECISION. Each Bank acknowledges that it has,
independently and without reliance upon the Administrative Agent, the
Syndication Agent or any other Bank, and based on such documents and information
as it has deemed appropriate, made its own credit analysis and decision to enter
into this Agreement. Each Bank also acknowledges that it will, independently and
without reliance upon the Administrative Agent, Syndication Agent or any other
Bank, and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit decisions in taking or not taking
any action under this Agreement.

         SECTION 7.8 SUCCESSOR ADMINISTRATIVE AGENT OR SYNDICATION AGENT. The
Administrative Agent or the Syndication Agent may resign at any time by giving
notice thereof to the Banks, the Borrower and each other and the Administrative
Agent or the Syndication Agent, as applicable, shall resign in the event its
Commitment is reduced to zero. Upon any such resignation, the Required Banks
shall have the right to appoint a successor Administrative Agent or Syndication
Agent, as applicable, which successor Administrative Agent or successor
Syndication Agent (as applicable) shall, provided no Event of Default has
occurred and is then continuing, be subject to Borrower's approval, which
approval shall not be unreasonably withheld or delayed (except that Borrower
shall, in all events, be deemed to have approved Bank of America, National
Association as a successor Syndication Agent and The Chase Manhattan Bank as a
successor Administrative Agent). If no successor Administrative Agent or
Syndication Agent (as applicable) shall have been so appointed by the Required
Banks and approved by the Borrower, or, if so appointed, shall not have accepted
such

                                       80

<PAGE>

appointment within 30 days after the retiring Administrative Agent or
Syndication Agent (as applicable) gives notice of resignation, then the retiring
Administrative Agent or retiring Syndication Agent (as applicable) may, on
behalf of the Banks, appoint a successor Administrative Agent or Syndication
Agent (as applicable), which shall be the Syndication Agent or the
Administrative Agent, as the case may be, who shall act until the Required Banks
shall appoint a Administrative Agent or Syndication Agent. Upon the acceptance
of its appointment as the Administrative Agent or Syndication Agent hereunder by
a successor Administrative Agent or successor Syndication Agent, as applicable,
such successor Administrative Agent or successor Syndication Agent, as
applicable, shall thereupon succeed to and become vested with all the rights and
duties of the retiring Administrative Agent or retiring Syndication Agent, as
applicable, and the retiring Administrative Agent or the retiring Syndication
Agent, as applicable, shall be discharged from its duties and obligations
hereunder. The rights and duties of the Administrative Agent to be vested in any
successor Administrative Agent shall include, without limitation, the rights and
duties as Swingline Lender. After any retiring Administrative Agent's or
retiring Syndication Agent's resignation hereunder, the provisions of this
Article shall inure to its benefit as to any actions taken or omitted to be
taken by it while it was the Administrative Agent or the Syndication Agent, as
applicable. For gross negligence or willful misconduct, as determined by all the
Banks (excluding for such determination Administrative Agent or Syndication
Agent in its capacity as a Bank, as applicable), Administrative Agent or
Syndication Agent may be removed at any time by giving at least thirty (30)
Domestic Business Days prior written notice to Administrative Agent, Syndication
Agent and Borrower. Such resignation or removal shall take effect upon the
acceptance of appointment by a successor Administrative Agent or Syndication
Agent, as applicable, in accordance with the provisions of this Section 7.8.

         SECTION 7.9 CONSENTS AND APPROVALS. All communications from
Administrative Agent to the Banks requesting the Banks' determination, consent,
approval or disapproval (i) shall be given in the form of a written notice to
each Bank, (ii) shall be accompanied by a description of the matter or item as
to which such determination, approval, consent or disapproval is requested, or
shall advise each Bank where such matter or item may be inspected, or shall
otherwise describe the matter or issue to be resolved, (iii) shall include, if
reasonably requested by a Bank and to the extent not previously provided to such
Bank, written materials and a summary of all oral information provided to
Administrative Agent by Borrower in respect of the matter or issue to be
resolved, and (iv) shall include Administrative Agent's recommended course of
action or determination in respect thereof. Each Bank shall reply promptly, but
in any event within ten (10) Domestic Business Days after receipt of the request
therefor from Administrative Agent (the "BANK REPLY PERIOD"). Unless a Bank
shall give written notice to Administrative Agent

                                       81

<PAGE>

that it objects to the recommendation or determination of Administrative Agent
(together with a written explanation of the reasons behind such objection)
within the Bank Reply Period, such Bank shall be deemed to have approved of or
consented to such recommendation or determination. With respect to decisions
requiring the approval of the Required Banks or all the Banks, Administrative
Agent shall submit its recommendation or determination for approval of or
consent to such recommendation or determination to all Banks and upon receiving
the required approval or consent shall follow the course of action or
determination of the Required Banks (and each non-responding Bank shall be
deemed to have concurred with such recommended course of action) or all the
Banks, as the case may be.

                                  ARTICLE VIII

                             CHANGE IN CIRCUMSTANCES

         SECTION 8.1 BASIS FOR DETERMINING INTEREST RATE INADEQUATE OR UNFAIR.
If on or prior to the first day of any Interest Period for any Euro-Dollar
Borrowing or Money Market LIBOR Loan:

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

         (b)   Banks having 50% or more of the aggregate amount of the
Commitments advise the Administrative Agent that the Adjusted London Interbank
Offered Rate, as determined by the Administrative Agent will not adequately and
fairly reflect the cost to such Bank of funding its Euro-Dollar Loans for such
Interest Period, the Administrative Agent shall forthwith give notice thereof to
the Borrower and the Banks, whereupon until the Administrative Agent notifies
the Borrower that the circumstances giving rise to such suspension no longer
exist, the obligations of the Banks to make Euro-Dollar Loans shall be
suspended. Unless the Borrower notifies the Administrative Agent at least two
Domestic Business Days before the date of (i) any Euro-Dollar Borrowing for
which a Notice of Borrowing has previously been given that it elects not to
borrow on such date, such Borrowing shall instead be made as a Base Rate
Borrowing, or (ii) any Money Market LIBOR Borrowing for which a Notice of Money
Market Borrowing has previously been given, the Money Market LIBOR Loans
comprising such Borrowing shall bear interest for each day from and including
the first day to but excluding the last day of the Interest Period applicable
thereto at the Base Rate for such day. For purposes of this Section 8.1(b), in
determining whether the Adjusted London Interbank Offered Rate, as determined by
Administrative Agent, will not adequately and fairly reflect the cost to any
Bank of funding its Euro-Dollar Loans for such

                                       82

<PAGE>

Interest Period, such determination will be based solely on the ability of such
Bank to obtain matching funds in the London interbank market at a reasonably
equivalent rate.

         SECTION 8.2 ILLEGALITY. If, on or after the date of this Agreement, the
adoption of any applicable law, rule or regulation, or any change in any
applicable law, rule or regulation, or any change in the interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by any Bank (or its Euro-Dollar Lending Office) with any request or directive
(whether or not having the force of law) made after the Closing Date of any such
authority, central bank or comparable agency shall make it unlawful for any Bank
(or its Euro-Dollar Lending Office) (x) to make, maintain or fund its
Euro-Dollar Loans, or (y) to participate in any Letter of Credit issued by the
Fronting Bank, or, with respect to the Fronting Bank, to issue any Letter of
Credit, the Administrative Agent shall forthwith give notice thereof to the
other Banks and the Borrower, whereupon until such Bank notifies the Borrower
and the Administrative Agent that the circumstances giving rise to such
suspension no longer exist, the obligation of such Bank in case of the event
described in clause (x) above to make Euro-Dollar Loans, or in the case of the
event described in clause (y) above, to participate in any Letter of Credit
issued by the Fronting Bank or, with respect to the Fronting Bank, to issue any
Letter of Credit, shall be suspended. With respect to Euro-Dollar Loans, before
giving any notice to the Administrative Agent pursuant to this Section, such
Bank shall designate a different Euro-Dollar Lending Office if such designation
will avoid the need for giving such notice and will not, in the judgment of such
Bank, be otherwise disadvantageous to such Bank. If such Bank shall determine
that it may not lawfully continue to maintain and fund any of its outstanding
Euro-Dollar Loans to maturity and shall so specify in such notice, the Borrower
shall be deemed to have delivered a Notice of Interest Rate Election and such
Euro-Dollar Loan shall be converted as of such date to a Base Rate Loan (without
payment of any amounts that Borrower would otherwise be obligated to pay
pursuant to Section 2.13 hereof with respect to Loans converted pursuant to this
Section 8.2) in an equal principal amount from such Bank (on which interest and
principal shall be payable contemporaneously with the related Euro-Dollar Loans
of the other Banks), and such Bank shall make such a Base Rate Loan.

         If at any time, it shall be unlawful for any Bank to make, maintain or
fund its Euro-Dollar Loans, the Borrower shall have the right, upon five (5)
Domestic Business Day's notice to the Administrative Agent, to either (x) cause
a bank, reasonably acceptable to the Administrative Agent, to offer to purchase
the Commitments of such Bank for an amount equal to such Bank's outstanding
Loans, and to become a Bank hereunder, or obtain the agreement of one or more
existing Banks to offer to purchase the Commitments of such Bank for such
amount, which offer such Bank

                                       83

<PAGE>

is hereby required to accept, or (y) to repay in full all Loans then outstanding
of such Bank, together with interest and all other amounts due thereon, upon
which event, such Bank's Commitments shall be deemed to be cancelled pursuant to
Section 2.11(c).

         SECTION 8.3 INCREASED COST AND REDUCED RETURN.

         (a)   If, on or after (x) the date hereof in the case of Committed
Loans made pursuant to Section 2.1, or (y) the date of the related Money Market
Quote, in the case of any Money Market Loan, the adoption of any applicable law,
rule or regulation, or any change in any applicable law, rule or regulation, or
any change in the interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by any Bank (or its Applicable Lending
Office) with any request or directive (whether or not having the force of law)
made at the Closing Date of any such authority, central bank or comparable
agency shall impose, modify or deem applicable any reserve (including, without
limitation, any such requirement imposed by the Board of Governors of the
Federal Reserve System (but excluding with respect to any Euro-Dollar Loan any
such requirement reflected in an applicable Euro-Dollar Reserve Percentage)),
special deposit, insurance assessment or similar requirement against assets of,
deposits with or for the account of, or credit extended by, any Bank (or its
Applicable Lending Office) or shall impose on any Bank (or its Applicable
Lending Office) or on the London interbank market any other condition materially
more burdensome in nature, extent or consequence than those in existence as of
the Closing Date affecting such Bank's Euro-Dollar Loans, its Note, or its
obligation to make Euro-Dollar Loans, and the result of any of the foregoing is
to increase the cost to such Bank (or its Applicable Lending Office) of making
or maintaining any Euro-Dollar Loan, or to reduce the amount of any sum received
or receivable by such Bank (or its Applicable Lending Office) under this
Agreement or under its Note with respect to such Euro-Dollar Loans, by an amount
deemed by such Bank to be material, then, within 15 days after demand by such
Bank (with a copy to the Administrative Agent), the Borrower shall pay to such
Bank such additional amount or amounts (based upon a reasonable allocation
thereof by such Bank to the Euro-Dollar Loans made by such Bank hereunder) as
will compensate such Bank for such increased cost or reduction to the extent
such Bank generally imposes such additional amounts on other borrowers of such
Bank in similar circumstances.

         (b)   If any Bank shall have reasonably determined that, after the date
hereof, the adoption of any applicable law, rule or regulation regarding capital
adequacy, or any change in any such law, rule or regulation, or any change in
the interpretation or administration thereof by any governmental authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or any request or directive regarding

                                       84

<PAGE>

capital adequacy (whether or not having the force of law) made after the Closing
Date of any such authority, central bank or comparable agency, has or would have
the effect of reducing the rate of return on capital of such Bank (or its
Parent) as a consequence of such Bank's obligations hereunder to a level below
that which such Bank (or its Parent) could have achieved but for such adoption,
change, request or directive (taking into consideration its policies with
respect to capital adequacy) by an amount reasonably deemed by such Bank to be
material, then from time to time, within 15 days after demand by such Bank (with
a copy to the Administrative Agent), the Borrower shall pay to such Bank such
additional amount or amounts as will compensate such Bank (or its Parent) for
such reduction to the extent such Bank generally imposes such additional amounts
on other borrowers of such Bank in similar circumstances.

         (c)   Each Bank will promptly notify the Borrower, the Administrative
Agent of any event of which it has knowledge, occurring after the date hereof,
which will entitle such Bank to compensation pursuant to this Section and will
designate a different Applicable Lending Office if such designation will avoid
the need for, or reduce the amount of, such compensation and will not, in the
reasonable judgment of such Bank, be otherwise disadvantageous to such Bank. If
such Bank shall fail to notify Borrower of any such event within 90 days
following the end of the month during which such event occurred, then Borrower's
liability for any amounts described in this Section incurred by such Bank as a
result of such event shall be limited to those attributable to the period
occurring subsequent to the ninetieth (90th) day prior to the date upon which
such Bank actually notified Borrower of the occurrence of such event. A
certificate of any Bank claiming compensation under this Section and setting
forth a reasonably detailed calculation of the additional amount or amounts to
be paid to it hereunder shall be conclusive in the absence of demonstrable
error. In determining such amount, such Bank may use any reasonable averaging
and attribution methods.

         (d)   If at any time, any Bank shall be owed amounts pursuant to this
Section 8.3, the Borrower shall have the right, upon five (5) Domestic Business
Day's notice to the Administrative Agent to either (x) cause a bank, reasonably
acceptable to the Administrative Agent, to offer to purchase the Commitments of
such Bank for an amount equal to such Bank's outstanding Loans, and to become a
Bank hereunder, or to obtain the agreement of one or more existing Banks to
offer to purchase the Commitments of such Bank for such amount, which offer such
Bank is hereby required to accept, or (y) to repay in full all Loans then
outstanding of such Bank, together with interest and all other amounts due
thereon, upon which event, such Bank's Commitment shall be deemed to be
cancelled pursuant to Section 2.11(c).

         SECTION 8.4 TAXES.

         (a)   Any and all payments by the Borrower to or for the account of any
Bank or the Administrative Agent hereunder or under any other Loan Document
shall be made free and clear of and without deduction for any and all present or
future taxes, duties, levies, imposts, deductions, charges or withholdings, and
all liabilities with respect thereto, EXCLUDING, in the case of each Bank, the
Administrative Agent, taxes imposed on its income, and franchise taxes imposed
on it, by the jurisdiction under the laws of which such Bank or the
Administrative Agent (as the case may be) is organized or any political
subdivision thereof and, in the case of each Bank, taxes imposed on its income,
and franchise or similar taxes imposed on it, by the jurisdiction of such Bank's
Applicable Lending Office or any political subdivision thereof or by any other
jurisdiction (or any political subdivision thereof) as a result of a present or
former connection between such Bank or Administrative Agent and such other
jurisdiction or by the United States (all such non-excluded taxes, duties,
levies, imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as "NON-EXCLUDED TAXES"). If the Borrower shall be
required by law to deduct any Non-Excluded Taxes from or in respect of any sum
payable hereunder or under any Note or Letter of Credit, (i) the sum payable
shall be increased as necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this Section
8.4) such Bank, the Fronting Bank or the Administrative Agent (as the case may
be) receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower shall make such deductions, (iii) the
Borrower shall pay the full amount deducted to the relevant taxation authority
or other authority in accordance with applicable law and (iv) the Borrower shall
furnish to the Administrative Agent, at its address referred to in Section 9.1,
the original or a certified copy of a receipt evidencing payment thereof.

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

         (c)   The Borrower agrees to indemnify each Bank, the Fronting Bank and
the Administrative Agent for the full amount of Non-Excluded Taxes or Other
Taxes (including, without limitation, any Non-Excluded Taxes or Other Taxes
imposed or asserted by any jurisdiction on amounts payable under this Section
8.4) paid by such Bank, the Fronting Bank or the Administrative Agent (as the
case may be) and, so long as such Bank or Administrative Agent has promptly paid
any such Non-Excluded Taxes or Other Taxes, any liability for penalties and
interest arising therefrom or with

                                       86

<PAGE>

respect thereto. This indemnification shall be made within 15 days from the date
such Bank, the Fronting Bank or the Administrative Agent (as the case may be)
makes demand therefor.

         (d)   Each Bank organized under the laws of a jurisdiction outside the
United States, on or prior to the date of its execution and delivery of this
Agreement in the case of each Bank listed on the signature pages hereof and on
or prior to the date on which it becomes a Bank in the case of each other Bank,
shall provide the Borrower with (A) two duly completed copies of Internal
Revenue Service form 1001 or 4224, as appropriate, or any successor form
prescribed by the Internal Revenue Service, and (B) an Internal Revenue Service
Form W-8 or W-9, or any successor form prescribed by the Internal Revenue
Service, and shall provide Borrower with two further copies of any such form or
certification on or before the date that any such form or certification expires
or becomes obsolete and after the occurrence of any event requiring a change in
the most recent form previously delivered by it to Borrower, certifying (i) in
the case of a Form 1001 or 4224, that such Bank is entitled to benefits under an
income tax treaty to which the United States is a party which reduces the rate
of withholding tax on payments of interest or certifying that the income
receivable pursuant to this Agreement is effectively connected with the conduct
of a trade or business in the United States, and (ii) in the case of a Form W-8
or W-9, that it is entitled to an exemption from United States backup
withholding tax. If the form provided by a Bank at the time such Bank first
becomes a party to this Agreement indicates a United States interest withholding
tax rate in excess of zero, withholding tax at such rate shall be considered
excluded from "Non-Excluded Taxes" as defined in Section 8.4(a).

         (e)   For any period with respect to which a Bank has failed to provide
the Borrower with the appropriate form pursuant to Section 8.4(d) (unless such
failure is due to a change in treaty, law or regulation occurring subsequent to
the date on which a form originally was required to be provided), such Bank
shall not be entitled to indemnification under Section 8.4(c) with respect to
Non-Excluded Taxes imposed by the United States; PROVIDED, HOWEVER, that should
a Bank, which is otherwise exempt from or subject to a reduced rate of
withholding tax, become subject to Non-Excluded Taxes because of its failure to
deliver a form required hereunder, the Borrower shall take such steps as such
Bank shall reasonably request to assist such Bank to recover such Taxes so long
as Borrower shall incur no cost or liability as a result thereof.

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

                                       87

<PAGE>

         (g)   If at any time, any Bank shall be owed amounts pursuant to this
Section 8.4, the Borrower shall have the right, upon five (5) Domestic Business
Day's notice to the Administrative Agent to either (x) cause a bank, reasonably
acceptable to the Administrative Agent, to offer to purchase the Commitments of
such Bank for an amount equal to such Bank's outstanding Loans, and to become a
Bank hereunder, or to obtain the agreement of one or more existing Banks to
offer to purchase the Commitments of such Bank for such amount, which offer such
Bank is hereby required to accept, or (y) to repay in full all Loans then
outstanding of such Bank, together with interest and all other amounts due
thereon, upon which event, such Bank's Commitment shall be deemed to be
cancelled pursuant to Section 2.11(c).

         SECTION 8.5 BASE RATE LOANS SUBSTITUTED FOR AFFECTED EURO-DOLLAR LOANS.
If (i) the obligation of any Bank to make Euro-Dollar Loans has been suspended
pursuant to Section 8.2 or (ii) any Bank has demanded compensation under Section
8.3 or 8.4 with respect to its Euro-Dollar Loans and the Borrower shall, by at
least five Euro-Dollar Business Days' prior notice to such Bank through the
Administrative Agent, have elected that the provisions of this Section shall
apply to such Bank, then, unless and until such Bank notifies the Borrower that
the circumstances giving rise to such suspension or demand for compensation no
longer exist:

         (a)   Borrower shall be deemed to have delivered a Notice of Interest
Rate Election with respect to such affected Euro-Dollar Loans and thereafter all
Loans which would otherwise be made by such Bank as Euro-Dollar Loans shall be
made instead as Base Rate Loans (on which interest and principal shall be
payable contemporaneously with the related Euro-Dollar Loans of the other
Banks), and

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

         (c)   Borrower will not be required to make any payment which would
otherwise be required by Section 2.13 with respect to such Euro-Dollar Loans
converted to Base Rate Loans pursuant to clause (a) above.

                                   ARTICLE IX

                                  MISCELLANEOUS

         SECTION 9.1 NOTICES. All notices, requests and other communications to
any party hereunder shall be in writing (including bank wire, facsimile

such party: (x) in the case of the Borrower or the Administrative Agent, at its
address, or facsimile number set forth on the signature pages hereof with a
duplicate copy thereof, in the case of the Borrower, to the Borrower, at Equity
Residential Properties Trust, Two North Riverside Plaza, Suite 400, Chicago,
Illinois 60606, Attn: General Counsel, and to Rosenberg & Liebentritt, P.C., Two
North Riverside Plaza, Suite 1515, Chicago, Illinois 60606, Attn: James M.
Phipps, Esq., (y) in the case of any Bank, at its address, or facsimile number
set forth in its Administrative Questionnaire or (z) in the case of any party,
such other address, or facsimile number as such party may hereafter specify for
the purpose by notice to the Administrative Agent and the Borrower. Each such
notice, request or other communication shall be effective (i) if given by
facsimile transmission, when such facsimile is transmitted to the facsimile

confirmation is received, (ii) if given by certified registered mail, return
receipt requested, with first class postage prepaid, addressed as aforesaid,

recognized overnight carrier, 24 hours after such communication is deposited
with such carrier with postage prepaid for next day delivery, or (iv) if given
by any other means, when delivered at the address specified in this Section;
PROVIDED that notices to the Administrative Agent under Article II or Article
VIII shall not be effective until received.

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

         SECTION 9.3 EXPENSES; INDEMNIFICATION.

         (a)   The Borrower shall pay within thirty (30) days after written
notice from the Administrative Agent, (i) all reasonable out-of-pocket costs and
expenses of the Administrative Agent and the Syndication Agent (including
reasonable fees and disbursements of special counsel Skadden, Arps, Slate,
Meagher & Flom LLP), in connection with the preparation of this Agreement, the
Loan Documents and the documents and instruments referred to therein, and any
waiver or consent hereunder or any amendment hereof or any Default or alleged
Default hereunder, (ii) all reasonable fees and disbursements of special counsel
Skadden, Arps, Slate, Meagher & Flom LLP in connection with the syndication of
the Loans and (iii) if an Event of Default occurs, all reasonable out-of-pocket
expenses incurred by the Administrative Agent and each Bank, including fees and
disbursements of counsel for the Administrative Agent and each of the Banks, in
connection with the enforcement of the Loan

                                       89

<PAGE>

Documents and the instruments referred to therein and such Event of Default and
collection, bankruptcy, insolvency and other enforcement proceedings resulting
therefrom; provided, however, that the attorneys' fees and disbursements for
which Borrower is obligated under this subsection (a)(iii) shall be limited to
the reasonable non-duplicative fees and disbursements of (A) counsel for
Administrative Agent, and (B) counsel for all of the Banks as a group; and
provided, further, that all other costs and expenses for which Borrower is
obligated under this subsection (a)(iii) shall be limited to the reasonable
non-duplicative costs and expenses of Administrative Agent. For purposes of this
Section 9.3(a)(iii), (1) counsel for Administrative Agent shall mean a single
outside law firm representing Administrative Agent, and (2) counsel for all of
the Banks as a group shall mean a single outside law firm representing such
Banks as a group (which law firm may or may not be the same law firm
representing either or both of Administrative Agent and/or Syndication Agent).

         (b)   The Borrower agrees to indemnify the Syndication Agent, the
Administrative Agent and each Bank, their respective affiliates and the
respective directors, officers, agents and employees of the foregoing (each an
"INDEMNITEE") and hold each Indemnitee harmless from and against any and all
liabilities, losses, damages, costs and expenses of any kind, including, without
limitation, the reasonable fees and disbursements of counsel, which may be
incurred by such Indemnitee in connection with any investigative, administrative
or judicial proceeding that may at any time (including, without limitation, at
any time following the payment of the Obligations) be asserted against any
Indemnitee, as a result of, or arising out of, or in any way related to or by
reason of, (i) any of the transactions contemplated by the Loan Documents or the
execution, delivery or performance of any Loan Document, (ii) any violation by
the Borrower, EQR or the Environmental Affiliates of any applicable
Environmental Law, (iii) any Environmental Claim arising out of the management,
use, control, ownership or operation of property or assets by the Borrower, EQR
or any of the Environmental Affiliates, including, without limitation, all
on-site and off-site activities of Borrower or any Environmental Affiliate
involving Materials of Environmental Concern, (iv) the breach of any
environmental representation or warranty set forth herein, but excluding those
liabilities, losses, damages, costs and expenses (a) for which such Indemnitee
has been compensated pursuant to the terms of this Agreement, (b) incurred
solely by reason of the gross negligence, wilful misconduct, bad faith or fraud
of any Indemnitee as finally determined by a court of competent jurisdiction,
(c) violations of Environmental Laws relating to a Property which are caused by
the act or omission of such Indemnitee after such Indemnitee takes possession of
such Property or (d) any liability of such Indemnitee to any third party based
upon contractual obligations of such Indemnitee owing to such third party which
are not expressly set forth in the Loan Documents. In addition, the
indemnification set forth in this Section 9.3(b) in favor of any director,
officer, agent or

                                       90

<PAGE>

employee of Administrative Agent, Syndication Agent or any Bank shall be solely
in his or her respective capacity as such director, officer, agent or employee.
The Borrower's obligations under this Section shall survive the termination of
this Agreement and the payment of the Obligations.

         SECTION 9.4 SHARING OF SET-OFFS. In addition to any rights now or
hereafter granted under applicable law or otherwise, and not by way of
limitation of any such rights, upon the occurrence and during the continuance of
any Event of Default, each Bank is hereby authorized at any time or from time to
time, without presentment, demand, protest or other notice of any kind to the
Borrower or to any other Person, any such notice being hereby expressly waived,
but subject to the prior consent of the Administrative Agent, to set off and to
appropriate and apply any and all deposits (general or special, time or demand,
provisional or final) and any other indebtedness at any time held or owing by
such Bank (including, without limitation, by branches and agencies of such Bank
wherever located) to or for the credit or the account of the Borrower against
and on account of the Obligations of the Borrower then due and payable to such
Bank under this Agreement or under any of the other Loan Documents, including,
without limitation, all interests in Obligations purchased by such Bank. Each
Bank agrees that if it shall by exercising any right of set-off or counterclaim
or otherwise, receive payment of a proportion of the aggregate amount of
principal and interest due with respect to any Note held by it or Letter of
Credit participated in by it, or, in the case of the Fronting Bank, Letter of
Credit issued by it, which is greater than the proportion received by any other
Bank or Letter of Credit issued or participated in by such other Bank, the Bank
receiving such proportionately greater payment shall purchase such
participations in the Notes held by the other Banks, and such other adjustments
shall be made, as may be required so that all such payments of principal and
interest with respect to the Notes held by the Banks or Letter of Credit issued
or participated in by such other Banks shall be shared by the Banks pro rata;
PROVIDED that nothing in this Section shall impair the right of any Bank to
exercise any right of set-off or counterclaim it may have to any deposits not
received in connection with the Loans and to apply the amount subject to such
exercise to the payment of indebtedness of the Borrower other than its
indebtedness under the Notes or the Letters of Credit. The Borrower agrees, to
the fullest extent it may effectively do so under applicable law, that any
holder of a participation in a Note or a Letter of Credit, whether or not
acquired pursuant to the foregoing arrangements, may exercise rights of set-off
or counterclaim and other rights with respect to such participation as fully as
if such holder of a participation were a direct creditor of the Borrower in the
amount of such participation. Notwithstanding anything to the contrary contained
herein, any Bank may, by separate agreement with the Borrower, waive its right
to set off contained herein or granted by law and any such

                                       91

<PAGE>

written waiver shall be effective against such Bank under this Section 9.4.

         SECTION 9.5 AMENDMENTS AND WAIVERS. Any provision of this Agreement or
the Notes, the Letters of Credit or other Loan Documents may be amended or
waived if, but only if, such amendment or waiver is in writing and is signed by
the Borrower and the Required Banks (and, if the rights or duties of the
Administrative Agent or the Swingline Lender in its capacity as Administrative
Agent or Swingline Lender, as applicable, are affected thereby, by the
Administrative Agent or Swingline Lender, as applicable); PROVIDED that no such
amendment or waiver with respect to this Agreement, the Notes, the Letters of
Credit or any other Loan Documents shall, unless signed by all the Banks, (i)
increase or decrease the Commitment of any Bank (except for a ratable decrease
in the Commitments of all Banks) or subject any Bank to any additional
obligation, (ii) reduce the principal of or rate of interest on any Loan or any
fees hereunder, (iii) postpone the date fixed for any payment of principal of or
interest on any Loan or any fees hereunder or for any reduction or termination
of any Commitment, (iv) change the percentage of the Commitments or of the
aggregate unpaid principal amount of the Notes, or the number of Banks, which
shall be required for the Banks or any of them to take any action under this
Section or any other provision of this Agreement, (v) release the EQR Guaranty
or (vi) modify the provisions of this Section 9.5.

         SECTION 9.6 SUCCESSORS AND ASSIGNS.

         (a)   The provisions of this Agreement shall be binding upon and inure
to the benefit of the parties hereto and their respective successors and
assigns, except that the Borrower may not assign or otherwise transfer any of
its rights under this Agreement or the other Loan Documents without the prior
written consent of all Banks and the Administrative Agent and any Bank may not
assign or otherwise transfer any of its interest under this Agreement except as
permitted in subsection (b) and (c) of this Section 9.6.

         (b)   Any Bank may at any time grant (i) prior to the occurrence of an
Event of Default, to an existing Bank, one or more banks, finance companies,
insurance companies or other financial institutions in minimum amounts of not
less than $10,000,000 (or any lesser amount in the case of participations to an
existing Bank or in the case of participations with respect to Money Market
Loans only) and (ii) after the occurrence and during the continuance of an Event
of Default, to any Person in any amount (in each case, a "PARTICIPANT"),
participating interests in its Commitment or any or all of its Loans, with (and
subject to) the consent of the Administrative Agent (other than with respect to
Money Market Loans) and, provided that no Event of Default shall have occurred
and be continuing, the Borrower (other than with respect to Money Market Loans),
which consent

                                       92

<PAGE>

shall not be unreasonably withheld or delayed. Any participation made during the
continuation of an Event of Default shall not be affected by the subsequent cure
of such Event of Default. In the event of any such grant by a Bank of a
participating interest to a Participant, whether or not upon notice to the
Borrower and the Administrative Agent, such Bank shall remain responsible for
the performance of its obligations hereunder, and the Borrower and the
Administrative Agent shall continue to deal solely and directly with such Bank
in connection with such Bank's rights and obligations under this Agreement. Any
agreement pursuant to which any Bank may grant such a participating interest
shall provide that such Bank shall retain the sole right and responsibility to
enforce the obligations of the Borrower hereunder including, without limitation,
the right to approve any amendment, modification or waiver of any provision of
this Agreement; PROVIDED that such participation agreement may provide that such
Bank will not agree to any modification, amendment or waiver of this Agreement
described in clause (i), (ii), (iii), (iv) or (v) of Section 9.5 without the
consent of the Participant. The Borrower agrees that each Participant shall, to
the extent provided in its participation agreement, be entitled to the benefits
of Article VIII with respect to its participating interest. An assignment or
other transfer which is not permitted by subsection (c) or (d) below shall be
given effect for purposes of this Agreement only to the extent of, and subject
to the restrictions with respect to, a participating interest granted in
accordance with this subsection (b).

         (c)   Any Bank may at any time assign to (i) prior to the occurrence of
an Event of Default, an existing Bank or one or more banks, finance companies,
insurance or other financial institutions which (A) has (or, in the case of a
bank which is a subsidiary, such bank's parent has) a rating of its senior debt
obligations of not less than Baa-1 by Moody's Investors Service or a comparable
rating by a rating agency acceptable to Administrative Agent and (B) has total
assets in excess of Ten Billion Dollars ($10,000,000,000), in minimum amounts of
not less than Ten Million Dollars ($10,000,000) and integral multiples of One
Million Dollars ($1,000,000) thereafter (or any lesser amount in the case of
assignments to an existing Bank) and (ii) after the occurrence and during the
continuance of an Event of Default, to any Person in any amount (in each case,
an "ASSIGNEE"), all or a proportionate part of all, of its rights and
obligations under this Agreement, the Notes and the other Loan Documents, and,
in either case, such Assignee shall assume such rights and obligations, pursuant
to a Transfer Supplement in substantially the form of EXHIBIT "E" hereto
executed by such Assignee and such transferor Bank, with (and subject to) the
consent of the Administrative Agent and, provided that no Event of Default shall
have occurred and be continuing, the Borrower, which consent shall not be
unreasonably withheld or delayed; PROVIDED that if an Assignee is an affiliate
of such transferor Bank or was a Bank immediately prior to such assignment, no
such consent shall be required; and PROVIDED FURTHER that such assignment may,
but need

                                       93

<PAGE>

not, include rights of the transferor Bank in respect of outstanding Money
Market Loans. Upon execution and delivery of such instrument and payment by such
Assignee to such transferor Bank of an amount equal to the purchase price agreed
between such transferor Bank and such Assignee, such Assignee shall be a Bank
party to this Agreement and shall have all the rights and obligations of a Bank
with a Commitment as set forth in such instrument of assumption, and no further
consent or action by any party shall be required and the transferor Bank shall
be released from its obligations hereunder to a corresponding extent. Upon the
consummation of any assignment pursuant to this subsection (c), the transferor
Bank, the Administrative Agent and the Borrower shall make appropriate
arrangements so that, if required, a new Note is issued to the Assignee. In
connection with any such assignment, the transferor Bank shall pay to the
Administrative Agent an administrative fee for processing such assignment in the
amount of $2,500. If the Assignee is not incorporated under the laws of the
United States of America or a state thereof, it shall deliver to the Borrower
and the Administrative Agent certification as to exemption from deduction or
withholding of any United States federal income taxes in accordance with Section
8.4. Any assignment made during the continuation of an Event of Default shall
not be affected by any subsequent cure of such Event of Default.

         (d)   Any Bank (each, a "DESIGNATING LENDER") may at any time designate
one Designated Lender to fund Money Market Loans on behalf of such Designating
Lender subject to the terms of this Section 9.6(d) and the provisions in Section
9.6(b) and (c) shall not apply to such designation. No Bank may designate more
than one (1) Designated Lender at any one time. The parties to each such
designation shall execute and deliver to the Administrative Agent for its
acceptance a Designation Agreement. Upon such receipt of an appropriately
completed Designation Agreement executed by a Designating Lender and a designee
representing that it is a Designated Lender, the Administrative Agent will
accept such Designation Agreement and will give prompt notice thereof to the
Borrower, whereupon, (i) the Borrower shall execute and deliver to the
Designating Lender a Designated Lender Note payable to the order of the
Designated Lender, (ii) from and after the effective date specified in the
Designation Agreement, the Designated Lender shall become a party to this
Agreement with a right (subject to the provisions of Section 2.3(b)) to make
Money Market Loans on behalf of its Designating Lender pursuant to Section 2.3
after the Borrower has accepted a Money Market Loan (or portion thereof) of the
Designating Lender, and (iii) the Designated Lender shall not be required to
make payments with respect to any obligations in this Agreement except to the
extent of excess cash flow of such Designated Lender which is not otherwise
required to repay obligations of such Designated Lender which are then due and
payable; provided, however, that regardless of such designation and assumption
by the Designated Lender, the Designating Lender shall be and remain obligated
to the Borrower, the Administrative Agent and the Banks for each and

                                       94

<PAGE>

every of the obligations of the Designating Lender and its related Designated
Lender with respect to this Agreement, including, without limitation, any
indemnification obligations under Section 7.6 hereof and any sums otherwise
payable to the Borrower by the Designated Lender. Each Designating Lender shall
serve as the administrative agent of the Designated Lender and shall on behalf
of, and to the exclusion of, the Designated Lender: (i) receive any and all
payments made for the benefit of the Designated Lender and (ii) give and receive
all communications and notices and take all actions hereunder, including,
without limitation, votes, approvals, waivers, consents and amendments under or
relating to this Agreement and the other Loan Documents. Any such notice,
communication, vote, approval, waiver, consent or amendment shall be signed by
the Designating Lender as administrative agent for the Designated Lender and
shall not be signed by the Designated Lender on its own behalf and shall be
binding upon the Designated Lender to the same extent as if signed by the
Designated Lender on its own behalf. The Borrower, the Administrative Agent and
the Banks may rely thereon without any requirement that the Designated Lender
sign or acknowledge the same. No Designated Lender may assign or transfer all or
any portion of its interest hereunder or under any other Loan Document, other
than assignments to the Designating Lender which originally designated such
Designated Lender or otherwise in accordance with the provisions of Section 9.6
(b) and (c).

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

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

         SECTION 9.7 COLLATERAL. Each of the Banks represents to the
Administrative Agent and each of the other Banks that it in good faith is not
relying upon any "margin stock" (as defined in Regulation U) as collateral in
the extension or maintenance of the credit provided for in this Agreement.

         SECTION 9.8 GOVERNING LAW; SUBMISSION TO JURISDICTION.

         (a)   THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HEREUNDER AND

THE STATE OF ILLINOIS (WITHOUT GIVING EFFECT TO THE PRINCIPLES THEREOF RELATING
TO CONFLICTS OF LAW).

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

         SECTION 9.9 COUNTERPARTS; INTEGRATION; EFFECTIVENESS. This Agreement
may be signed in any number of counterparts, each of which shall be an original,
with the same effect as if the signatures thereto and hereto were upon the same
instrument. This Agreement constitutes the entire agreement and understanding
among the parties hereto and supersedes any and all prior agreements and
understandings, oral or written, relating to the subject matter hereof. This
Agreement shall become effective upon receipt by the Administrative Agent and
the Borrower of counterparts hereof signed by each of the parties hereto (or, in
the case of any party as to which an executed counterpart shall not have been
received, receipt by the Administrative Agent in form satisfactory to it of
telegraphic or other written confirmation from such party of execution of a
counterpart hereof by such party).

         SECTION 9.10 WAIVER OF JURY TRIAL. EACH OF THE BORROWER, THE
ADMINISTRATIVE AGENT, THE SYNDICATION AGENT AND THE BANKS HEREBY IRREVOCABLY
WAIVE ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF

         SECTION 9.11 SURVIVAL. All indemnities set forth herein shall survive
the execution and delivery of this Agreement

                                       96

and the other Loan Documents and the making and repayment of the Loans
hereunder.

         SECTION 9.12 DOMICILE OF LOANS. Each Bank may transfer and carry its
Loans at, to or for the account of any domestic or foreign branch office,
subsidiary or affiliate of such Bank.

         SECTION 9.13 LIMITATION OF LIABILITY. No claim may be made by the
Borrower or any other Person acting by or through Borrower against the
Administrative Agent or any Bank or the affiliates, directors, officers,
employees, attorneys or agent of any of them for any consequential or punitive
damages in respect of any claim for breach of contract or any other theory of
liability arising out of or related to the transactions contemplated by this
Agreement or by the other Loan Documents, or any act, omission or event
occurring in connection therewith; and the Borrower hereby waives, releases and
agrees not to sue upon any claim for any such damages, whether or not accrued
and whether or not known or suspected to exist in its favor.

         SECTION 9.14 RECOURSE OBLIGATION. This Agreement and the Obligations
hereunder are fully recourse to the Borrower. Notwithstanding the foregoing, no
recourse under or upon any obligation, covenant, or agreement contained in this
Agreement shall be had against any officer, director, shareholder or employee of
the Borrower or EQR except in the event of fraud or misappropriation of funds on
the part of such officer, director, shareholder or employee.

         SECTION 9.15 CONFIDENTIALITY. The Administrative Agent and each Bank
shall use reasonable efforts to assure that information about Borrower, EQR and
its Subsidiaries and Investments Affiliates, and the Properties thereof and
their operations, affairs and financial condition, not generally disclosed to
the public, which is furnished to Administrative Agent or any Bank pursuant to
the provisions hereof or any other Loan Document is used only for the purposes
of this Agreement and shall not be divulged to any Person other than the
Administrative Agent, the Banks, and their affiliates and respective officers,
directors, employees and agents who are actively and directly participating in
the evaluation, administration or enforcement of the Loan, except: (a) to their
attorneys and accountants, (b) in connection with the enforcement of the rights
and exercise of any remedies of the Administrative Agent and the Banks hereunder
and under the other Loan Documents, (c) in connection with assignments and
participations and the solicitation of prospective assignees and participants
referred to in Section 9.6 hereof, who have agreed in writing to be bound by a

         SECTION 9.16 BANK'S FAILURE TO FUND.

         (a)   Unless the Administrative Agent shall have received notice from a
Bank prior to the date of any Borrowing that such Bank will not make available
to the Administrative Agent such Bank's share of such Borrowing, the
Administrative Agent may assume that such Bank has made such share available to
the Administrative Agent on the date of such Borrowing in accordance with
subsection (b) of Section 2.4 or Section 2.16(e) hereof, and the Administrative
Agent may, in reliance upon such assumption, make available to Borrower on such
date a corresponding amount. If and to the extent that such Bank shall not have
so made such share available to the Administrative Agent, such Bank and Borrower
severally agree to repay to the Administrative Agent forthwith on demand such
corresponding amount together with interest thereon, in accordance with the
provisions of Section 2.4(c) or Section 2.16(e) hereof. If such Bank shall repay
to the Administrative Agent such corresponding amount, such amount so repaid
shall constitute such Bank's Loan included in such Borrowing for purposes of
this Agreement. Nothing contained in this Section or Sections 2.4(c) or 2.16(e)
shall be deemed to reduce the Commitment of any Bank or in any way affect the
rights of Borrower with respect to any defaulting Bank or Administrative Agent.
The failure of any Bank to make available to the Administrative Agent such
Bank's share of any Borrowing in accordance with Sections 2.4(b) or 2.16(e)
hereof shall not relieve any other Bank of its obligations to fund its
Commitment, in accordance with the provisions hereof.

         (b)   If a Bank does not advance to Administrative Agent such Bank's
pro rata share of a Loan in accordance herewith, then neither Administrative
Agent nor the other Banks shall be required or obligated to fund such Bank's pro
rata share of such Loan.

         (c)   As used herein, the following terms shall have the meanings set
forth below:

         (i)   "DEFAULTING BANK" shall mean any Bank which (x) does not advance
to the Administrative Agent such Bank's pro rata share of a Loan in accordance
herewith for a period of five (5) Domestic Business Days after notice of such
failure from Administrative Agent, (y) shall otherwise fail to perform such
Bank's obligations under the Loan Documents for a period of five (5) Domestic
Business Days after notice of such failure from Administrative Agent, or (z)
shall fail to pay the Administrative Agent or any other Bank, as the case may
be, upon demand, such Bank's pro rata share of any costs, expenses or
disbursements incurred or made by the Administrative Agent pursuant to the terms
of the Loan Documents for a period of five (5) Domestic Business Days after
notice of such failure from Administrative Agent, and in all cases, such failure
is not as a result of a good faith dispute as to whether such advance is
properly

                                       98

<PAGE>

required to be made pursuant to the provisions of this Agreement, or as to
whether such other performance or payment is properly required pursuant to the
provisions of this Agreement.

         (ii)  "JUNIOR CREDITOR" means any Defaulting Bank which has not (x)
fully cured each and every default on its part under the Loan Documents and (y)
unconditionally tendered to the Administrative Agent such Defaulting Bank's pro
rata share of all costs, expenses and disbursements required to be paid or
reimbursed pursuant to the terms of the Loan Documents.

         (iii) "PAYMENT IN FULL" means, as of any date, the receipt by the Banks
who are not Junior Creditors of an amount of cash, in lawful currency of the
United States, sufficient to indefeasibly pay in full all Senior Debt.

         (iv)  "SENIOR DEBT" means (x) collectively, any and all indebtedness,
obligations and liabilities of the Borrower to the Banks who are not Junior
Creditors from time to time, whether fixed or contingent, direct or indirect,
joint or several, due or not due, liquidated or unliquidated, determined or
undetermined, arising by contract, operation of law or otherwise, whether on
open account or evidenced by one or more instruments, and whether for principal,
premium, interest (including, without limitation, interest accruing after the
filing of a petition initiating any proceeding referred to in Section 6.1(f) or
(g)), reimbursement for fees, indemnities, costs, expenses or otherwise, which
arise under, in connection with or in respect of the Loans or the Loan
Documents, and (y) any and all deferrals, renewals, extensions and refundings
of, or amendments, restatements, rearrangements, modifications or supplements
to, any such indebtedness, obligation or liability.

         (v)   "SUBORDINATED DEBT" means (x) any and all indebtedness,
obligations and liabilities of Borrower to one or more Junior Creditors from
time to time, whether fixed or contingent, direct or indirect, joint or several,
due or not due, liquidated or unliquidated, determined or undetermined, arising
by contract, operation of law or otherwise, whether on open account or evidenced
by one or more instruments, and whether for principal, premium, interest
(including, without limitation, interest accruing after the filing of a petition
initiating any proceeding referred to in Section 6.1(f) or (g)), reimbursement
for fees, indemnities, costs, expenses or otherwise, which arise under, in
connection with or in respect of the Loans or the Loan Documents, and (y) any
and all deferrals, renewals, extensions and refundings of, or amendments,
restatements, rearrangements, modifications or supplements to, any such
indebtedness, obligation or liability.

         (d)   Immediately upon a Bank's becoming a Junior Creditor, no Junior
Creditor shall, prior to Payment in Full of all Senior Debt:

                                       99

<PAGE>

         (i)   accelerate, demand payment of, sue upon, collect, or receive any
payment upon, in any manner, or satisfy or otherwise discharge, any Subordinated
Debt, whether for principal, interest and otherwise;

         (ii)  take or enforce any Liens to secure Subordinated Debt or attach
or levy upon any assets of Borrower, to enforce any Subordinated Debt;

         (iii) enforce or apply any security for any Subordinated Debt; or

         (iv)  incur any debt or liability, or the like, to, or receive any
loan, return of capital, advance, gift or any other property, from, the
Borrower.

         (e)   In the event of:

         (i)   any insolvency, bankruptcy, receivership, liquidation,
dissolution, reorganization, readjustment, composition or other similar
proceeding relating to Borrower;

         (ii)  any liquidation, dissolution or other winding-up of the Borrower,
voluntary or involuntary, whether or not involving insolvency, reorganization or
bankruptcy proceedings;

         (iii) any assignment by the Borrower for the benefit of creditors;

         (iv)  any sale or other transfer of all or substantially all assets of
the Borrower; or

         (v)   any other marshalling of the assets of the Borrower;

each of the Banks shall first have received Payment in Full of all Senior Debt
before any payment or distribution, whether in cash, securities or other
property, shall be made in respect of or upon any Subordinated Debt. Any payment
or distribution, whether in cash, securities or other property that would
otherwise be payable or deliverable in respect of Subordinated Debt to any
Junior Creditor but for this Agreement shall be paid or delivered directly to
the Administrative Agent for distribution to the Banks in accordance with this
Agreement until Payment in Full of all Senior Debt. If any Junior Creditor
receives any such payment or distribution, it shall promptly pay over or deliver
the same to the Administrative Agent for application in accordance with the
preceding sentence.

         (f)   Each Junior Creditor shall file in any bankruptcy or other
proceeding of Borrower in which the filing of claims is required by law, all
claims relating to Subordinated Debt that such Junior Creditor may have against
Borrower and assign to the Banks who are not Junior Creditors all rights of such
Junior

                                      100
<PAGE>

Creditor thereunder. If such Junior Creditor does not file any such claim
prior to forty-five (45) days before the expiration of the time to file such
claim, Administrative Agent, as attorney-in-fact for such Junior Creditor, is
hereby irrevocably authorized to do so in the name of such Junior Creditor
or, in Administrative Agent's sole discretion, to assign the claim to a
nominee and to cause proof of claim to be filed in the name of such nominee.
The foregoing power of attorney is coupled with an interest and cannot be
revoked. The Administrative Agent shall, to the exclusion of each Junior
Creditor, have the sole right, subject to Section 9.5 hereof, to accept or
reject any plan proposed in any such proceeding and to take any other action
that a party filing a claim is entitled to take. In all such cases, whether
in administration, bankruptcy or otherwise, the Person or Persons authorized
to pay such claim shall pay to Administrative Agent the amount payable on
such claim and, to the full extent necessary for that purpose, each Junior
Creditor hereby transfers and assigns to the Administrative Agent all of the
Junior Creditor's rights to any such payments or distributions to which
Junior Creditor would otherwise be entitled.

         (g)   (i) If any payment or distribution of any character or any
security, whether in cash, securities or other property, shall be received by
any Junior Creditor in contravention of any of the terms hereof, such payment or
distribution or security shall be received in trust for the benefit of, and
shall promptly be paid over or delivered and transferred to, Administrative
Agent for application to the payment of all Senior Debt, to the extent necessary
to achieve Payment in Full. In the event of the failure of any Junior Creditor
to endorse or assign any such payment, distribution or security, Administrative
Agent is hereby irrevocably authorized to endorse or assign the same as
attorney-in-fact for such Junior Creditor.

         (ii)  Each Junior Creditor shall take such action (including, without
limitation, the execution and filing of a financing statement with respect to
this Agreement and the execution, verification, delivery and filing of proofs of
claim, consents, assignments or other instructions that Administrative Agent may
require from time to time in order to prove or realize upon any rights or claims
pertaining to Subordinated Debt or to effectuate the full benefit of the
subordination contained herein) as may, in Administrative Agent's sole and
absolute discretion, be necessary or desirable to assure the effectiveness of
the subordination effected by this Agreement.

         (h)   (i) Each Bank that becomes a Junior Creditor understands and
acknowledges by its execution hereof that each other Bank is entering into this
Agreement and the Loan Documents in reliance upon the absolute subordination in
right of payment and in time of payment of Subordinated Debt to Senior Debt as
set forth herein.

                                      101

<PAGE>

         (ii)  Only upon the Payment in Full of all Senior Debt shall any Junior
Creditor be subrogated to any remaining rights of the Banks which are not
Defaulting Banks to receive payments or distributions of assets of the Borrower
made on or applicable to any Senior Debt.

         (iii) Each Junior Creditor agrees that it will deliver all instruments
or other writings evidencing any Subordinated Debt held by it to Administrative
Agent, promptly after request therefor by the Administrative Agent.

         (iv)  No Junior Creditor may at any time sell, assign or otherwise
transfer any Subordinated Debt, or any portion thereof, including, without
limitation, the granting of any Lien thereon, unless and until satisfaction of
the requirements of Section 9.6 above and the proposed transferee shall have
assumed in writing the obligation of the Junior Creditor to the Banks under this
Agreement, in a form acceptable to the Administrative Agent.

         (v)   If any of the Senior Debt, should be invalidated, avoided or set
aside, the subordination provided for herein nevertheless shall continue in full
force and effect and, as between the Banks which are not Defaulting Banks and
all Junior Creditors, shall be and be deemed to remain in full force and effect.

         (vi)  Each Junior Creditor hereby irrevocably waives, in respect of
Subordinated Debt, all rights (x) under Sections 361 through 365, 502(e) and 509
of the Bankruptcy Code (or any similar sections hereafter in effect under any
other Federal or state laws or legal or equitable principles relating to
bankruptcy, insolvency, reorganizations, liquidations or otherwise for the
relief of debtors or protection of creditors), and (y) to seek or obtain
conversion to a different type of proceeding or to seek or obtain dismissal of a
proceeding, in each case in relation to a bankruptcy, reorganization, insolvency
or other proceeding under similar laws with respect to the Borrower. Without
limiting the generality of the foregoing, each Junior Creditor hereby
specifically waives (A) the right to seek to give credit (secured or otherwise)
to the Borrower in any way under Section 364 of the Bankruptcy Code unless the
same is subordinated in all respects to Senior Debt in a manner acceptable to
Administrative Agent in its sole and absolute discretion and (B) the right to
receive any collateral security (including any "super priority" or equal or
"priming" or replacement Lien) for any Subordinated Debt unless the Banks which
are not Defaulting Banks have received a senior position acceptable to the Banks
in their sole and absolute discretion to secure all Senior Debt (in the same
collateral to the extent collateral is involved).

         (i)   (i) In addition to and not in limitation of the subordination
effected by this Section 9.16, the

                                      102

<PAGE>

Administrative Agent and each of the Banks which are not Defaulting Banks may in
their respective sole and absolute discretion, also exercise any and all other
rights and remedies available at law or in equity in respect of a Defaulting
Bank; and

         (ii)  The Administrative Agent shall give each of the Banks notice of
the occurrence of a default under this Section 9.16 by a Defaulting Bank and if
the Administrative Agent and/or one or more of the other Banks shall, at their
option, fund any amounts required to be paid or advanced by a Defaulting Bank,
the other Banks who have elected not to fund any portion of such amounts shall
not be liable for any reimbursements to the Administrative Agent and/or to such
other funding Banks.

         (j)   Notwithstanding anything to the contrary contained or implied
herein, a Defaulting Bank shall not be entitled to vote on any matter as to
which a vote by the Banks is required hereunder, including, without limitation,
any actions or consents on the part of the Administrative Agent as to which the
approval or consent of all the Banks or the Required Banks is required under
Article VIII, Section 9.5 or elsewhere, so long as such Bank is a Defaulting
Bank; provided, however, that in the case of any vote requiring the unanimous
consent of the Banks, if all the Banks other than the Defaulting Bank shall have
voted in accordance with each other, then the Defaulting Bank shall be deemed to
have voted in accordance with such Banks.

         (k)   Each of the Administrative Agent and any one or more of the Banks
which are not Defaulting Banks may, at their respective option, (i) advance to
the Borrower such Bank's pro rata share of the Loans not advanced by a
Defaulting Bank in accordance with the Loan Documents, or (ii) pay to the
Administrative Agent such Bank's pro rata share of any costs, expenses or
disbursements incurred or made by the Administrative Agent pursuant to the terms
of this Agreement not theretofore paid by a Defaulting Bank. Immediately upon
the making of any such advance by the Administrative Agent or any one of the
Banks, such Bank's pro rata share and the pro rata share of the Defaulting Bank
shall be recalculated to reflect such advance. All payments, repayments and
other disbursements of funds by the Administrative Agent to Banks shall
thereupon and, at all times thereafter be made in accordance with such Bank's
recalculated pro rata share unless and until a Defaulting Bank shall fully cure
all defaults on the part of such Defaulting Bank under the Loan Documents or
otherwise existing in respect of the Loans or this Agreement, at which time the
pro rata share of the Bank(s) which advanced sums on behalf of the Defaulting
Bank and of the Defaulting Bank shall be restored to their original percentages.

         SECTION 9.17 NO BANKRUPTCY PROCEEDINGS. Each of the Borrower, the Banks
and the Administrative Agent hereby agrees that it will not institute against
any Designated Lender or join any other Person in instituting against any
Designated Lender any

                                      103

bankruptcy, reorganization, arrangement, insolvency or liquidation proceeding
under any federal or state bankruptcy or similar law, until the later to occur
of (i) one year and one day after the payment in full of the latest maturing
commercial paper note issued by such Designated Lender and (ii) the Maturity
Date.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be

defined in the Credit Agreement are used herein with the same meaning.

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

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

              2. Except as set forth in Section 7 below, the Designor makes no
representation or warranty and assumes no responsibility pursuant to this
Designation Agreement with respect to (a) any statements, warranties or
representations made in or in connection with any Loan Document or the

Articles IV and V of the Credit Agreement and such other documents and

appropriate at the time, continue to make its own credit decisions in taking or
not taking action under any Loan Document; (c) confirms that it is a Designated
Lender; (d) appoints and authorizes the Administrative Agent to take such action
as agent on its behalf and to exercise such powers and discretion under any Loan
Document as are delegated to

perform in accordance with their terms all of the obligations which by the terms
of any Loan Document are required to be performed by it as a Bank.

              4. The Designee hereby appoints Designor as Designee's agent and

              6. The Administrative Agent hereby agrees that it will not
institute against any Designated Lender or join any other Person in instituting
against any Designated Lender any bankruptcy, reorganization, arrangement,
insolvency or liquidation proceeding under any federal or state bankruptcy or
similar law, until the later to occur of (i) one year and one day after the
payment in full of the latest maturing commercial paper note issued by such
Designated Lender and (ii) the Maturity Date.

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

                  FIRST AMENDMENT TO REVOLVING CREDIT AGREEMENT

              THIS FIRST AMENDMENT TO REVOLVING CREDIT AGREEMENT (this
"AMENDMENT") is made as of November 10, 1999, by and among ERP OPERATING LIMITED
PARTNERSHIP (the "BORROWER"), BANK OF AMERICA, NATIONAL ASSOCIATION, as
Administrative Agent (the "ADMINISTRATIVE AGENT"), THE CHASE MANHATTAN BANK, as
Syndication Agent, MORGAN GUARANTY TRUST COMPANY OF NEW YORK, as Documentation
Agent, and the BANKS listed on the signature pages hereof.

                              W I T N E S S E T H:

              WHEREAS, the Borrower and the Banks have entered into the
Revolving Credit Agreement, dated as of August 12, 1999 (the "CREDIT
AGREEMENT"); and

              WHEREAS, the parties desire to modify the Credit Agreement upon
the terms and conditions set forth herein.

              NOW THEREFORE, for good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the parties do hereby agree as
follows:

              1. DEFINITIONS. All capitalized terms not otherwise defined herein
shall have the meanings ascribed to them in the Credit Agreement.

<PAGE>

              2. LOAN DOCUMENTS. The definition "Loan Documents" is hereby
amended by adding the following after "and the Letter of Credit Documents": "and
any Guaranty".

              3. QUALIFYING UNENCUMBERED PROPERTY. The definition "Qualifying
Unencumbered Property" is hereby amended by adding the following after the last
sentence thereof:

                  Notwithstanding the foregoing, for the purposes of this
                  definition, a Property shall be deemed to be wholly-owned by
                  Borrower if such Property shall be owned by a Down REIT (as
                  hereinafter defined) or a wholly-owned Subsidiary of such Down
                  REIT. The term "Down REIT" shall mean a limited liability
                  company or limited partnership in which the only interest in
                  such Down REIT not owned (directly or indirectly) by Borrower
                  shall be preference interests or preference units,
                  respectively, and which limited liability company or limited
                  partnership, as the case may be (collectively, a "GUARANTOR"),
                  has executed and delivered to the Administrative Agent, on
                  behalf of the Banks, (i) a Guaranty of Payment in the form
                  attached hereto as EXHIBIT A (a "GUARANTY"), (ii) all
                  documents reasonably requested by the Administrative Agent
                  relating to the existence of such Down REIT, and the authority
                  for and validity of the Guaranty, including, without
                  limitation, the organizational documents of such Down REIT,
                  modified or supplemented prior to the date of such Guaranty,
                  each certified to be true, correct and complete by such Down
                  REIT, not more than ten (10) days prior to the date of such
                  Guaranty, together with a good standing certificate from the
                  Secretary of State (or the equivalent thereof) of the State of
                  formation of such Down REIT, to be dated not more than ten
                  (10) days prior to the date

                                        2

<PAGE>

                  of such Guaranty, as well as authorizing resolutions in
                  respect of the Guaranty, and (iii) an opinion of counsel with
                  respect to such Down REIT and Guaranty, in form and substance
                  reasonably acceptable to the Administrative Agent, with
                  respect to due organization, existence, good standing and
                  authority, and validity and enforceability of the Guaranty. In
                  addition, for purposes of this definition, a Guaranty shall
                  not be deemed to constitute Unsecured Debt of the applicable
                  Down REIT.

              4. LETTERS OF CREDIT. Sections 2.16(b) and (d) of the Credit
Agreement are hereby deleted.

              5. PERMITTED HOLDINGS. For purposes of calculating Multifamily
Residential Property Partnership Interests pursuant to Section 5.8(j) of the
Credit Agreement, a Down REIT (or a wholly-owned Subsidiary thereof) shall be
deemed to be wholly-owned by Borrower.

              6. GUARANTY. (i) Notwithstanding any other provision of the Credit
Agreement or any other Loan Document to the contrary, the Administrative Agent,
the Banks and Designated Lenders agree with Borrower that any funds, claims, or
distributions actually received by the Administrative Agent for the account of
any Bank or Designated Lender as a result of the enforcement of, or pursuant to,
any Guaranty, net of the Administrative Agent's and the Banks' expenses of
collection thereof (such net amount, "GUARANTY PROCEEDS"), shall be made
available for distribution equally and ratably (in proportion to the aggregate
amount of principal, interest and other

                                       3

<PAGE>

amounts then owed in respect of the Obligations or of an issuance of Public Debt
(as defined below), as the case may be) among the Administrative Agent, the
Banks and the Designated Lenders and the trustee or trustees of any Unsecured
Debt, not subordinated to the Obligations (or to the holders thereof), issued by
Borrower, before or after the Effective Date, in offerings registered under the
Securities Act of 1933, as amended, or in transactions exempt from registration
pursuant to rule 144A or Regulation 8 thereunder or listed on non-U.S.
securities exchanges ("PUBLIC DEBT"), and the Administrative Agent is hereby
authorized, by Borrower, by each Bank (on its own behalf and on behalf of its
Designated Lender, if any) and by each Guarantor by its execution and delivery
of a Guaranty, to make such Guaranty Proceeds so available. No Bank or
Designated Lender shall have any interest in any amount paid over by the
Administrative Agent to the trustee or trustees in respect of any Public Debt
(or to the holders thereof) pursuant to the foregoing authorization. This
Section 6 shall apply solely to Guaranty Proceeds, and not to any payments,
funds, claims or distributions received by the Administrative Agent, any Bank or
Designated Lender directly or indirectly from Borrower or any other Person other
than from a Guarantor pursuant to a Guaranty. Borrower is aware of the terms of
the

                                       4

<PAGE>

Guaranties, and specifically understands and agrees with the Administrative
Agent, the Banks and the Designated Lenders that, to the extent Guaranty
Proceeds are distributed to holders of Public Debt or their respective trustees,
such Guarantor has agreed that the Obligations will not be deemed reduced by any
such distributions and such Guarantor shall continue to make payments pursuant
to its Guaranty until such time as the Obligations have been paid in full (and
the Commitments have been terminated and any Letter of Credit returned), after
taking into account any such distributions of Guaranty Proceeds in respect of
Indebtedness other than the Obligations.

              (ii) Nothing contained herein shall be deemed (A) to limit,
    modify, or alter the rights of the Administrative Agent, the Banks and the
    Designated Lenders under any Guaranty, (b) to subordinate the Obligations to
    any Public Debt, or (C) to give any holder of Public Debt (or any trustee
    for such holder) any rights of subrogation.

              (iii) This Amendment and all Guaranties, are for the sole benefit
    of the Administrative Agent, the Banks and the Designated Lenders and their
    respective successors and assigns. Nothing contained herein or in any
    Guaranty shall be deemed for the benefit of any holder of Public Debt, or
    any trustee for such holder; nor shall

                                       5

<PAGE>

    anything contained herein or therein be construed to impose on the
    Administrative Agent, any Bank or any Designated Lender any fiduciary
    duties, obligations or responsibilities to the holders of any Public Debt or
    their trustees (including, but not limited to, any duty to pursue any
    Guarantor for payment under its Guaranty).
