                  "Applicable Fee Percentage" means the respective percentages
per annum determined, at any time, based on the range into which Borrower's
Credit Rating then falls, in accordance with the table set forth below. Any
change in Borrower's Credit Rating causing it to move to a different range on
the table shall effect an immediate change in the Applicable Fee Percentage. In

Ratings are not equivalent, the Applicable Fee Percentage shall be determined by
the lower of such two (2) Credit Ratings. In the event that Borrower receives
more than two (2) Credit Ratings, and such Credit Ratings are not all
equivalent, the Applicable Fee Percentage shall be determined by the higher of
the ratings from S&P and Moody's, provided that the rating from one of the other
Rating Agencies shall be at least equivalent to such higher rating; provided,
further, that if the rating from one of the other Rating Agencies is not at
least equivalent to the higher of the ratings from S&P and Moody's, then the
Applicable Fee Percentage shall be determined by the second (2nd) highest Credit
Rating. In the event that only one of the Rating Agencies shall have set
Borrower's Credit Rating, then the Applicable Fee Percentage shall be based on
such rating only.

Unencumbered Property located outside of the United States (after first taking
into account the adjustment provided in clause (aa) of this proviso) which would
cause such amount to exceed ten percent (10%) of the total Unencumbered Asset
Value at such time (after making all adjustments required by this proviso) will
be disregarded in determining Unencumbered Asset Value. Anything in the
foregoing to the contrary notwithstanding, in the event that Borrower, a
Financing Partnership or a Joint Venture Subsidiary disposes (for purposes of
this definition of "Unencumbered Asset Value", each, a "Disposition") of (x) an
interest in any Qualified Unencumbered Property (which was not acquired during
the Fiscal Quarter most recently ended), (y) a direct or indirect interest in
the owner of any such Property or (z) any such Property in such a manner that
results in Borrower holding a direct or indirect interest in such Property or
the owner of such Property, then, for purposes of the foregoing calculation of
Unencumbered Asset Value, such Property shall be treated as follows:

                           (A)      if, following a Disposition, an undivided
         interest in the Property is owned by Borrower or a Financing

         interest in the Property for the entire Fiscal Quarter most recently
         ended;

         Fiscal Quarter.

                  "Unencumbered Net Operating Income" means, for any period, for
all Qualifying Unencumbered Properties, the aggregate EBITDA attributable to

for such period, which adjustment shall be at the rate of One Dollar and Fifty
Cents ($1.50) per square foot per annum of office space leased as of the
applicable date of determination for all Qualifying Unencumbered Properties that

such period, such amount per square foot shall be pro-rated for the period of
ownership).

                  "United States" means the United States of America, including
the fifty states and the District of Columbia.

                  "Unsecured Debt" means the amount of Indebtedness for borrowed
money of EOPT Borrower and any Financing Partnership which is not Secured Debt,
including, without limitation, the amount of all then outstanding Loans, plus,
for the purpose of calculating the ratio of outstanding Unsecured Debt to
Unencumbered Asset Value, an amount equal to the Borrower's percentage ownership
interest (whether direct or indirect) in each Joint Venture Subsidiary which is
not a Consolidated Subsidiary times any Indebtedness for borrowed money of such
Joint Venture Subsidiary which is not Secured Debt.

                  "Unsecured Debt Service" means Debt Service payable in respect
of Unsecured Debt.

                  "Unused Commitments" shall mean an amount equal to all
unadvanced funds (other than unadvanced funds in connection with any
construction loan) which any third party is obligated to advance to Borrower or
another Person or otherwise pursuant to any loan document, written instrument or
otherwise.

                  SECTION I.2. Accounting Terms and Determinations. Unless
otherwise specified herein, all accounting terms used herein shall be
interpreted, all accounting determinations hereunder shall be made, and all
financial statements required to be delivered hereunder shall be prepared in
accordance with GAAP applied on a basis consistent (except for changes concurred
in by the Borrower's independent public accountants) with the most recent
audited consolidated financial statements of the Borrower and its Consolidated
Subsidiaries delivered to the Administrative Agent; provided that for purposes
of references to the financial results and information of "EOPT, on a
consolidated basis," EOPT shall be deemed to own one hundred percent (100%) of
the partnership interests in Borrower; and provided further that, if the
Borrower notifies the Administrative Agent that the Borrower wishes to amend any
covenant in Article V to eliminate the effect of any change in GAAP on the
operation of such covenant (or if the Administrative Agent notifies the Borrower
that the Required Banks wish to amend Article V for such purpose), then the
Borrower's compliance with such covenant shall be determined on the basis of
GAAP in effect immediately before the relevant change in GAAP became effective,
until either such notice is withdrawn or such covenant is amended in a manner
reasonably satisfactory to the Borrower and the Required Banks.

                  SECTION I.3. Types of Borrowings. The term "Borrowing" denotes
the aggregation of Loans of one or more Banks to be made to the Borrower
pursuant to Article 2 on the same date, all of which Loans are of the same type
(subject to Article 8) and, except in the case of Base Rate Loans and Swingline
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 IBOR 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

                                       29

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
2.4 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 2.3 in which
only the Swingline Lender participates (subject to the provisions of said
Section 2.3)).

                                   ARTICLE II

                                   THE CREDITS

                  SECTION II.1. Commitments to Lend. Each Bank severally agrees,
on the terms and conditions set forth in this Agreement, to make Loans to 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 by such Bank
at any one time outstanding plus such Bank's Pro Rata Share of Swingline Loans
outstanding at such time shall not exceed the amount of its Commitment. Each
Borrowing outstanding under this Section 2.1 shall be in an aggregate principal
amount of $5,000,000, 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 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. Subject to the limitations set
forth herein, up to $250,000,000 of amounts repaid pursuant to Section 2.11 (a)
and (b) may be reborrowed one or more times , provided that (i) no amounts in
excess of such $250,000,000 may be reborrowed and (ii) no amounts required to be
repaid pursuant to Section 2.11(c), (d) or (e) may be reborrowed.

                  SECTION II.2. Notice of Borrowing. (a) With respect to any
Committed Borrowing, the Borrower shall give Administrative Agent notice not
later than 12:00 p.m. (New York, New York time) (x) one Business Day before each
Base Rate Borrowing, or (y) three Business Days before each Euro-Dollar
Borrowing, specifying:

                  (i)      the date of such Borrowing, which shall be a Business
         Day in the case of a Base Rate Borrowing or a Business Day in the case
         of a Euro-Dollar Borrowing,

                  (ii)     the aggregate amount of such Borrowing,

                  (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.

                  SECTION II.3.  Swingline Loan Subfacility.

                  (a)      Swingline Commitment. Subject to the terms and
conditions of this Section 2.3, 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)
SEVENTY-FIVE MILLION DOLLARS ($75,000,000), 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 Borrowings.

                  (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 2:00 p.m. (New York, New York 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 Business Day and (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-Business Days from the date of
the applicable Swingline Borrowing, (B) the date of the next Committed Borrowing
or (C) the Maturity Date. 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-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 2.3(b)(iii) is hereinafter referred to as a
"Mandatory Borrowing". Each Bank hereby irrevocably agrees to make Committed
Loans promptly upon

                                       31

<PAGE>

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
Business Day if such notice is received after 1:00 P.M. (New York, New York
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 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 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 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 to Section 6.2), 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)
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 Rate. 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

                                       32

<PAGE>

it is repaid, at a rate per annum equal to the Federal Funds Rate plus the
Applicable Margin for Euro-Dollar Loans for such day.

                  SECTION II.4.  Money Market Borrowings.

                  (a)      The Money Market Option. From time to time during the
Term, and provided that at such time the Borrower maintains a Credit Rating of
at least BBB- or Baa3 (or their equivalent) from two (2) Rating Agencies at
least one (1) of which shall be S&P or Moody's, the Borrower may, as set forth
in this Section 2.4, request the Banks during the Term to make offers to make
Money Market Loans to the Borrower, not to exceed, at such time, the lesser of
(i) $350,000,000 (adjusted pro rata for changes in the aggregate Commitments),
and (ii) the aggregate Commitments less all Loans (excluding any Loans or any
portion thereof to be repaid from the proceeds of such Money Market Loans).
Subject to the provisions of this Agreement, the Borrower may repay any
outstanding Money Market Loan on any day which is a Business Day and any amounts
so repaid may be reborrowed, up to the amount available under this Section 2.4
at the time of such Borrowing, until the Business Day next preceding the
Maturity Date. The Banks may, but shall have no obligation to, make such offers
and the Borrower may, but shall have no obligation to, accept any such offers in
the manner set forth in this Section 2.4.

                  (b)      Money Market Quote Request. When the Borrower wishes
to request offers to make Money Market Loans under this Section, it shall
transmit to the Administrative Agent by telex or facsimile transmission a Money
Market Quote Request substantially in the form of Exhibit B hereto (a "Money
Market Quote Request") so as to be received not later than 12:00 P.M. (New York,
New York time) on (x) the fifth Business Day prior to the date of Borrowing
proposed therein, in the case of a IBOR Auction or (y) the Business Day
immediately preceding the date of Borrowing proposed therein, 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 the Banks not later than the date of the Money Market Quote Request for
the first IBOR Auction or Absolute Rate Auction for which such change is to be
effective) specifying:

                  (i)      the proposed date of Borrowing, which shall be a
         Business Day in the case of a IBOR Auction or a Business Day in the
         case of an Absolute Rate Auction,

                  (ii)     the aggregate amount of such Borrowing, which shall
         be $5,000,000 or a larger multiple of $100,000,

                  (iii)    the duration of the Interest Period applicable
         thereto (which shall not be less than 14 days or more than 90 days),
         subject to the provisions of the definition of Interest Period,

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

                  (v)      the aggregate amount of all Money Market Loans then
         outstanding.

                                       33

<PAGE>

The Borrower may request offers to make Money Market Loans for more than one
Interest Period in a single Money Market Quote Request. In no event may Borrower
give a Money Market Quote Request within ten (10) days of the giving of any
other Money Market Quote Request.

                  (c)      Invitation for Money Market Quotes. Promptly upon
receipt of a Money Market Quote Request, the Administrative Agent shall send to
the Banks by telex or facsimile transmission an "Invitation for Money Market
Quotes" substantially in the form of Exhibit C hereto, which shall constitute an
invitation by the Borrower to each Bank to submit Money Market Quotes offering
to make the Money Market Loans to which such Money Market Quote Request relates
in accordance with this Section.

                  (d)      Submission and Contents of Money Market Quotes.

                  1.       Each Bank may submit a Money Market Quote containing
an offer or offers to make Money Market Loans in response to any Invitation for
Money Market Quotes. Each Money Market Quote must comply with the requirements
of this subsection (d) and must be submitted to the Administrative Agent by
telex or facsimile transmission at its offices specified in or pursuant to
Section 9.1 not later than (x) 3:00 P.M. (New York, New York time) on the fourth
Business Day prior to the proposed date of Borrowing, in the case of a IBOR
Auction or (y) 10:30 A.M. (New York, New York time) on 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 IBOR Auction or Absolute Rate
Auction for which such change is to be effective); provided that Money Market
Quotes submitted by the Administrative Agent (or any affiliate of the
Administrative Agent) in the capacity of a Bank may be submitted, and may only
be submitted, if the Administrative Agent or such affiliate notifies the
Borrower of the terms of the offer or offers contained therein not later than
(x) one hour prior to the deadline for the other Banks, in the case of an IBOR
Auction or (y) one hour prior to the deadline for the other Banks, in the case
of an Absolute Rate Auction. Subject to Articles 3 and 6, any Money Market Quote
so made shall be irrevocable except with the written consent of the
Administrative Agent given on the instructions of the Borrower.

                  2.       Each Money Market Quote shall be in substantially the
form of Exhibit D hereto and shall in any case specify:

                  (i)      the proposed date of Borrowing,

                  (ii)     the principal amount of the Money Market Loan for
         which each such offer is being made, which principal amount (w) may be
         greater than or less than the Commitment of the quoting Bank, (x) must
         be $5,000,000 or a larger multiple of $100,000, (y) may not exceed the
         principal amount of Money Market Loans for which offers were requested
         and (z) may be subject to an aggregate limitation as to the principal

                                       34

<PAGE>

         amount of Money Market Loans for which offers being made by such
         quoting Bank may be accepted,

                  (iii)    the Interest Period(s) with respect to which each
         such offer is being made,

                  (iv)     in the case of an IBOR Auction, the margin above or
         below the applicable Euro-Dollar Rate (the "Money Market Margin")
         offered for each such Money Market Loan, expressed as a percentage
         (specified to the nearest 1/10,000th of 1%) to be added to or
         subtracted from such base rate,

                  (v)      in the case of an Absolute Rate Auction, the rate of
         interest per annum (specified to the nearest 1/10,000th of 1%) (the
         "Money Market Absolute Rate") offered for each such Money Market Loan,
         and

                  (vi)     the identity of the quoting Bank.

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

                  3.       Any Money Market Quote shall be disregarded if it:

                  (i)      is not substantially in conformity with Exhibit D
         hereto or does not specify all of the information required by
         subsection (d)(2) above;

                  (ii)     contains qualifying, conditional or similar language
         (except for an aggregate limitation as provided in subsection
         (d)(2)(ii) above);

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

                  (iv)     arrives after the time set forth in subsection
         (d)(1).

                  (e)      Notice to Borrower. The Administrative Agent shall
promptly (and in any event within one (1) Business Day after receipt thereof)
notify the Borrower in writing of the terms (x) of any Money Market Quote
submitted by a Bank that is in accordance with subsection (d) and (y) of any
Money Market Quote that amends, modifies or is otherwise inconsistent with a
previous Money Market Quote submitted by such Bank with respect to the same
Money Market Quote Request. Any such subsequent Money Market Quote shall be
disregarded by the Administrative Agent unless such subsequent Money Market
Quote is submitted solely to correct a manifest error in such former Money
Market Quote 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

                                       35

<PAGE>

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
11:00 A.M. (New York, New York time) on (x) the third Business Day prior to the
proposed date of Borrowing, in the case of an IBOR 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 IBOR Auction or Absolute Rate
Auction for which such change is to be effective), the Borrower shall notify the
Administrative Agent of its acceptance or non-acceptance of the offers so
notified to it pursuant to subsection (e). In the case of acceptance, such
notice (a "Notice of Money Market Borrowing") shall specify the aggregate
principal amount of offers for each Interest Period that are accepted. The
Borrower may accept any Money Market Quote in whole or in part; provided that:

                  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 $5,000,000 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)
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)      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.

                                       36

                  SECTION II.5.  Notice to Banks; Funding of Loans.

                  (a)      Upon receipt of a Notice of Borrowing from Borrower
in accordance with Section 2.2 hereof, the Administrative Agent shall, on the
date such Notice of Borrowing is received by the Administrative Agent, 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 2:00 p.m. (New York, New York time) on
the date of each Committed Borrowing (including without limitation each
Mandatory Borrowing) as indicated in the applicable Notice of Borrowing, each
Bank shall (except as provided in subsection (d) of this Section) make available
its share of such Committed Borrowing in Federal funds immediately available in
New York, New York, to the Administrative Agent at its address referred to in
Section 9.1.

                  (c)      Not later than 3:00 p.m. (New York, New York 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 New York, New York, to the Administrative
Agent at its address referred to in Section 9.1.

                  (d)      Unless the Administrative Agent shall have received
notice from a Bank prior to the time 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 of
this Section 2.5 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 agrees to repay to the Administrative Agent forthwith on demand
such corresponding amount together with interest thereon, for each day from the
date such amount is made available to the Borrower until the date such amount is
repaid to the Administrative Agent, at the rate of interest applicable to such
Borrowing hereunder. 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. If such Bank shall
not pay to Administrative Agent such corresponding amount after reasonable
attempts are made by Administrative Agent to collect such amounts from such
Bank, Borrower agrees to repay to Administrative Agent forthwith on demand such
corresponding amounts together with interest thereto, for each day from the date
such amount is made available to Borrower until the date such amount is repaid
to Administrative Agent, at the interest rate applicable thereto one (1)
Business Day after demand. Nothing contained in this Section 2.5(d) 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

                                       37

Agent. The failure of any Bank to make available to the Administrative Agent
such Bank's share of any Borrowing in accordance with Section 2.5(b) hereof
shall not relieve any other Bank of its obligations to fund its Commitment, in
accordance with the provisions hereof.

                  (e)      Subject to the provisions hereof, the Administrative
Agent shall make available each Borrowing to Borrower in Federal funds
immediately available in accordance with, and on the date set forth in, the
applicable Notice of Borrowing.

                  SECTION II.6.  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,
without limitation, 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 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 2.3(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

                                       38

<PAGE>

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 and no more than ten (10) Money Market Loans outstanding at any
one time.

                  SECTION II.7.  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 or as otherwise provided in Section 2.3 with
respect to Mandatory Borrowings. Thereafter, the Borrower may from time to time
elect to change or continue the type of interest rate borne by each Group of
Loans (subject in each case to the provisions of Article VIII), as follows:

                           (i)      if such Loans are Base Rate Loans, the
Borrower may elect to convert all or any portion of such Loans to Euro-Dollar
Loans as of any 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"), signed by an Authorized Officer, to the Administrative Agent at
least three (3) 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;

                                       39

<PAGE>

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

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

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

                  (c)      Upon receipt of a Notice of Interest Rate Election
from the Borrower pursuant to subsection (a) above, the 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.

                  SECTION II.8.  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 2.7, at a rate per annum equal to the Base Rate plus the Applicable
Margin for Base Rate Loans for such day.

                  (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 Euro-Dollar Rate applicable
to such Interest Period.

                  (c)      Subject to Section 8.1, each Money Market IBOR 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
Euro-Dollar Rate for such Interest Period (determined in accordance with Section
2.8(b) as if the related Money Market IBOR Borrowing were a Euro-Dollar
Borrowing) plus (or minus) the Money Market Margin quoted by the Bank making
such Loan in accordance with Section 2.4. 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 2.4. 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.

                                       40

<PAGE>

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

                  (f)      Intentionally Omitted.

                  (g)      Interest on all Loans (other than Base Rate Loans)
shall be payable on the last Business Day of each applicable Interest Period
(provided that in the event any Interest Period ends on the date which is 60 or
90 days after the date on which any Interest Period commences, interest on all
Loans (other than Base Rate Loans) shall be payable on the first Business Day of
each calendar month during such Interest Period and on the last day of such
Interest Period) and interest on Base Rate Loans shall be payable on the first
Business Day of each calendar month.

                  SECTION II.9.  Fees.

                  (a)      Facility Fee. For the period beginning on the Closing
Date and ending on the date the Obligations are paid in full and this Agreement
is terminated (the "Facility Fee Period"), the Borrower shall pay to the
Administrative Agent for the account of the Banks ratably in proportion to their
respective Commitments (1) for so long as the Borrower has an Investment Grade
Rating, a facility fee on the aggregate Commitments less all amounts repaid
pursuant to Section 2.11(c) or (d) or pursuant to Section 2.11 (a) or (b) if
such amount may not be reborrowed and at the Applicable Fee Percentage or (2) in
the event that the Borrower does not have an Investment Grade Rating, an unused
fee at an annual rate equal to the product of (i) the daily average aggregate
Commitments less the aggregate amount of all Loans then outstanding and less all
amounts repaid pursuant to Section 2.11(c) or (d) or pursuant to Section 2.11
(a) or (b) if such amount may not be reborrowed and (ii) the Applicable Fee
Percentage. The facility fee or, if applicable, the unused fee, shall be payable
in arrears on each January 1, April 1, July 1 and October 1 during the Facility
Fee Period.

                  (b)      Fees Non-Refundable. All fees set forth in this
Section 2.9 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, the Syndication Agent and the Banks regardless of whether
any Loans are actually made.

                  SECTION II.10.  Maturity Date; Extension.

                                       41

<PAGE>

                  (a)      The term (the "Term") of the Commitments (and each
Bank's obligations to make Loans hereunder) shall terminate and expire on the
Maturity Date.

                  (b)      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 II.11.  Prepayments.

                  (a)      The Borrower may, upon at least one (1) 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 together with
accrued interest thereon to the date of prepayment. The Borrower may, from time
to time on any Business Day so long as prior notice is given to the
Administrative Agent and Swingline Lender no later than 2:00 p.m. (New York, New
York 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 of all Swingline Loans then outstanding) by paying the
principal amount to be prepaid together with accrued interest thereon to the
date of prepayment no later than 3:00 p.m. (New York, New York time) on such
day. Each such optional prepayment shall be applied to prepay ratably the Loans
of the several Banks (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) 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. In addition, the Borrower may not prepay all or any portion of the
principal amount of any Money Market Loan prior to the end of the Interest
Period applicable thereto without the consent of all applicable Designated
Lenders and Banks. Any such prepayment shall be upon at least three (3) 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)      If, at any time, Borrower or EOPT receives Net
Offering Proceeds in the form of cash (other than drawings under this Agreement
or the Existing Facility or proceeds

                                       42

<PAGE>

received within ninety (90) days after the redemption, retirement or repurchase
of ownership or equity interests in Borrower or Guarantor, up to the amount paid
by Borrower or Guarantor in connection with such redemption, retirement or
repurchase, where, for the avoidance of doubt, the net effect is that neither
Borrower nor Guarantor shall have increased its Net Worth as a result of any
such proceeds), then, the Borrower shall repay the Loans as LIBOR tranches
expire in an amount equal to the lesser of (x) the aggregate Net Offering
Proceeds in the form of cash then received by Borrower and (y) the outstanding
Obligations, and, if and to the extent that the outstanding Obligations shall be
less than the amount of such Net Offering Proceeds, the Commitments shall be
reduced on a pro rata basis by an amount equal to the difference between such
Net Offering Proceeds and the outstanding Obligations. Borrower shall deliver a
Mandatory Prepayment Notice to the Administrative Agent within one (1) Business
Day after Borrower or EOPT receives any such Net Offering Proceeds.

                  (d)      If at any time Borrower or EOPT receives proceeds,
dividends or distributions relating to the sale or disposition of the Borrower's
interests in material Property or other assets (including, but not limited to,
Joint Venture Interests and equity interests in Subsidiaries), then, the
Borrower shall repay the Loans as LIBOR tranches expire in an amount equal to
the lesser of (x) the aggregate Net Price in the form of cash relating to such
sale or disposition received by the Borrower, and (y) the outstanding
Obligations, and, if and to the extent that the outstanding Obligations shall be
less than the amount of such Net Price, the Commitment Amount shall be reduced
by an amount equal to the difference between such Net Price and the outstanding
Obligations. Borrower shall deliver a Mandatory Prepayment Notice to the
Administrative Agent within one (1) Business Day after Borrower or EOPT receives
any such proceeds, dividends or distributions. Notwithstanding the foregoing,
however, (1) Borrower shall not be required to prepay any outstanding
Obligations, nor shall the Commitments be reduced, with respect to up to
$50,000,000 in aggregate proceeds, dividends or distributions in the form of
cash relating to sales or dispositions of the Borrower's interests in material
Properties or other assets (including, but not limited to, Joint Venture
Interests and equity interests in Subsidiaries) if and to the extent Borrower
uses such proceeds, dividends or distributions to purchase Real Property Assets,
provided that (i) Borrower identifies such Real Property Assets to
Administrative Agent within forty-five (45) days after the date of the receipt
of such proceeds, dividends or distributions and (ii) the purchase and sale of
one or more of such Real Property Assets closes within 180 days after the date
of the receipt of such proceeds, dividends or distributions; and (2) Borrower
shall not be required to prepay any outstanding Obligations, nor shall the
Commitments be reduced, as a result of the closing of the proposed joint venture
arrangement with TIAA CREF, anticipated to result in approximately $440,000,000
of net proceeds.

                  (e)      The Borrower may at any time and from time to time
cancel all or any part of the Commitments in amounts aggregating Ten Million
Dollars ($10,000,000) or any larger multiple of One Hundred Thousand Dollars
($100,000), by the delivery to the Administrative Agent of a notice of
cancellation, signed by an Authorized Officer, 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

                                       43

<PAGE>

canceled, upon at least three (3) Business Days' 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),
Borrower shall be permitted to designate in its notice of cancellation which
Loans, if any, are to be prepaid. In no event shall the Borrower be permitted to
cancel Commitments, if, after giving effect to such cancellation and any related
payments as well as any returns by Borrower, the amount of the Loans exceeds the
Commitments, as so reduced. A reduction of the Commitments pursuant to this
Section 2.11(e) 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)      Subject to the limitations set forth herein, up to
$250,000,000 of amounts repaid pursuant to Section 2.11 (a) and (b) may be
reborrowed one or more times, provided that (i) no amounts in excess of such
$250,000,000 may be reborrowed and (ii) no amounts required to be repaid
pursuant to Section 2.11(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.

                  SECTION II.12.  General Provisions as to Payments.

                  (a)      The Borrower shall make each payment of principal of
and interest on the Loans and of fees hereunder, not later than 12:00 p.m. (New
York, New York time) on the date when due, in Federal or other funds immediately
available in New York, New York, to the Administrative Agent at its address
referred to in Section 9.1. The Administrative Agent will promptly (and in any
event within one (1) Business Day after receipt thereof) 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 1:00 p.m. (New York, New York
time) on any Business Day, and Administrative Agent shall not have distributed
to any Bank its applicable share of such payment on such 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
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 Business Day, the date for payment thereof
shall be extended to the next succeeding 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 Business Day, the date for payment thereof shall be extended to the
next succeeding Business Day unless such Business Day falls in another calendar
month, in which case the date for payment thereof shall be the next preceding
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 Business Day, the date for
payment thereof shall be extended to the next succeeding Business Day. If the
date for any payment of principal

                                       44

<PAGE>

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 II.13. Funding Losses. If the Borrower makes any
payment of principal with respect to any Euro-Dollar Loan or Money Market IBOR
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 IBOR Loans after notice has been
given to any Bank in accordance with Section 2.5(a) or 2.4(f), as applicable, 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 (1st) 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 II.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).

                  SECTION II.15. Use of 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

material respects on and as of the date of such Borrowing both before and after
giving effect to the making of such Loans;

                  (e)      no law or regulation shall have been adopted, no

                  (f)      no event, act or condition shall have occurred after
the Closing Date which, in the reasonable judgment of the Administrative Agent
or the Required Banks, as the case may be, has had or is likely to have a
Material Adverse Effect; and

                  (g)      all Commitments (as defined in the Existing Revolving

Agreement or in any of the other Loan Documents.

                                   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

                                       48

<PAGE>

survive the effectiveness of this Agreement, the execution and delivery of the
other Loan Documents and the making of the Loans.

                  SECTION IV.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 Delaware and has all powers and all material governmental
licenses, authorizations, consents and approvals required to own its property
and assets and carry on its business as now conducted or as it presently
proposes to conduct and has been duly qualified and is in good standing in every
jurisdiction in which the failure to be so qualified and/or in good standing is
likely to have a Material Adverse Effect. EOPT 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 IV.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 and EOPT each have 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 and EOPT, 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. EOPT has the power and authority to execute, deliver and carry out the
terms and provisions of each of the Loan Documents to which it is a party and
has taken all necessary action to authorize the execution, delivery and
performance of such Loan Documents. EOPT 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.

                  SECTION IV.3.  No Violation.

                  (a)      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

                                       49

<PAGE>

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 (except for such breaches and
defaults under loan agreements which the lenders thereunder have agreed to
forbear pursuant to valid forbearance agreements), 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).

                  (b)      Neither the execution, delivery or performance by
EOPT of the Loan Documents to which it is a party, nor compliance by EOPT 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 EOPT 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 EOPT (or of any partnership of
which EOPT 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
(except for such breaches and defaults under loan agreements which the lenders
thereunder have agreed to forbear pursuant to valid forbearance agreements), or
(iii) will cause a material default by EOPT under any organizational document of
any Person in which EOPT has an interest, 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 IV.4.  Financial Information.

                  (a)      The consolidated balance sheets of EOPT and the
Borrower as of December 31, 2002 and as of September 30, 2003, and the related
statements of operations and cash flows of EOPT and the Borrower for the fiscal
year or quarter then ended, reported on by Ernst & Young LLP, fairly present, in
conformity with GAAP, the consolidated financial position of EOPT and the
Borrower, as the case may be, as of such date and the consolidated results of
operations and cash flows for such fiscal year.

                  (b)      Since September 30, 2003, (i) except as may have been
disclosed in writing to the Banks, nothing has occurred having a Material
Adverse Effect, and (ii) except as set forth on Schedule 4.4(b), neither the
Borrower nor EOPT has incurred any material indebtedness or guaranty on or
before the Closing Date.

                                       50

<PAGE>

                  SECTION IV.5. Litigation. Except as previously disclosed by
the Borrower in writing to the Banks, there is no action, suit, proceeding or
investigation pending against, or to the knowledge of the Borrower threatened
against or affecting, (i) the Borrower, EOPT 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. As of the
Closing Date, no such action, suit or proceeding exists.

                  SECTION IV.6.  Compliance with ERISA.

                  (a)      Except as set forth on Schedule 4.6 attached hereto,
neither Borrower nor EOPT is a member of or has entered into, maintained,
contributed to, or been required to contribute to, or may incur any liability
with respect to any Plan or Multiemployer Plan or any other Benefit Arrangement.
In the event that at any time after the Closing Date, either the Borrower or
EOPT shall become a member of any other material Plan or Multiemployer Plan,
Borrower promptly shall notify the Administrative Agent thereof and from and
after such notice Schedule 4.6 shall be deemed modified thereby.

                  (b)      Except for a "prohibited transaction" arising solely
because of a Bank's breach of the covenant set forth in Section 9.17 hereof, 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 any of the
Banks to any tax or penalty on prohibited transactions imposed under Section
4975 of the Code or Section 502(i) of ERISA and such transactions will not
otherwise result in the Administrative Agent or any of the Banks being deemed in
violation of Sections 404 or 406 of ERISA or Section 4975 of the Code or in the
Administrative Agent or any of the Banks being a fiduciary or party in interest
under ERISA or a "disqualified person" as defined in Section 4975(e)(2) of the
Code with respect to an "employee benefit plan" within the meaning of Section
3(3) of ERISA or a "plan" within the meaning of Section 4975(e)(1) of the Code.
No assets of Borrower constitute "assets" (within the meaning of ERISA or
Section 4975 of the Code, including, but not limited to, 29 C.F.R. ss.
2510.3-101 or any successor regulation thereto) of an "employee benefit plan"
within the meaning of Section 3(3) of ERISA or a "plan" within the meaning of
Section 4975(e)(1) of the Code. In addition to the prohibitions set forth in
this Agreement and the other Loan Documents, and not in limitation thereof,
Borrower covenants and agrees that Borrower shall not use any "assets" (within
the meaning of ERISA or Section 4975 of the Code, including but not limited to
29 C.F.R. ss. 2510.3-101) of an "employee benefit plan" within the meaning of
Section 3(3) of ERISA or a "plan" within the meaning of Section 4975(e)(1) of
the Code to repay or secure the Note, the Loan, or the Obligations.

                  SECTION IV.7. Environmental. The Borrower conducts reviews of
the effect of Environmental Laws on the business, operations and properties of
the Borrower and its Consolidated Subsidiaries when necessary in the course of
which it identifies and evaluates

                                       51

<PAGE>

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, without limitation, employees, and any related costs and expenses).
On the basis of this review, the Borrower has reasonably concluded that such
associated liabilities and costs, including, without limitation, the costs of
compliance with Environmental Laws, are unlikely to have a Material Adverse
Effect.

                  SECTION IV.8. Taxes. The Borrower, EOPT 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, EOPT 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, EOPT and their Consolidated Subsidiaries in respect of taxes or other
governmental charges are, in the opinion of the Borrower, adequate.

                  SECTION IV.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 IV.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 and EOPT will be Solvent.

                  SECTION IV.11. Use of Proceeds. All proceeds of the Loans will
be used by the Borrower only in accordance with the provisions hereof. 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 IV.12. Governmental Approvals. No order, consent,
approval, license, authorization, or validation of, or filing, recording or
registration with, or exemption by, any Governmental 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;

                                       52

<PAGE>

                  SECTION IV.13. Investment Company Act; Public Utility Holding
Company Act. Neither the Borrower, EOPT 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 "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 IV.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, Chicago, Illinois 60606.

                  SECTION IV.15. REIT Status. EOPT is qualified and EOPT intends
to continue to qualify as a real estate investment trust under the Code.

                  SECTION IV.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 IV.17. Judgments. There are no final, non-appealable
judgments or decrees in an aggregate amount of Five Million Dollars ($5,000,000)
or more entered by a court or courts of competent jurisdiction against EOPT or
the Borrower or, to the extent such judgment would be recourse to EOPT or
Borrower, any of its Consolidated Subsidiaries (other than judgments as to
which, and only to the extent, a reputable insurance company has acknowledged
coverage of such claim in writing or which have been paid or stayed).

                  SECTION IV.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 IV.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 IV.20. Compliance With Law. To the Borrower's
knowledge, the Borrower and each of its Real Property Assets are in compliance
with all laws, rules, regulations,

                                       53

<PAGE>

orders, 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 IV.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 IV.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, the Syndication Agent and the Banks, and certain other
Persons as previously disclosed in writing to the Administrative Agent.

                  SECTION IV.23. Labor Matters. Except as disclosed on Schedule
4.6, as of the Closing Date, there are no collective bargaining agreements or
Multiemployer Plans covering the employees of the Borrower or any member of the
ERISA Group and neither the Borrower nor any member of the ERISA Group has
suffered any strikes, walkouts, work stoppages or other material labor
difficulty within the last five years.

                  SECTION IV.24. Insurance. The Borrower currently maintains
insurance at 100% replacement cost insurance coverage (subject to customary
deductibles) in respect of each of its Real Property Assets, as well as
commercial general liability insurance (including, without limitation,
"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 owners of assets such as Borrower's
directly or indirectly owned Real Property Assets would maintain.

                  SECTION IV.25. Organizational Documents. The documents
delivered pursuant to Section 3.1(e) constitute, as of the Closing Date, all of
the organizational documents (together with all amendments and modifications
thereof) of the Borrower and EOPT. The Borrower represents that it has delivered
to the Administrative Agent true, correct and complete copies of each such
documents, except for exhibits to Borrower's partnership agreement identifying
the current list of partners which, with the permission of the Banks, has been
omitted therefrom. EOPT holds (directly or indirectly) an 89.06% ownership
interest in the Borrower as of the date hereof.

                  SECTION IV.26. Qualifying Unencumbered Properties. As of the
date hereof, each Property listed on Schedule 1.1 as a Qualifying Unencumbered
Property (i) is an operating Office Building or Parking Property wholly-owned or
ground leased (directly or beneficially) by Borrower, a Financing Partnership or
a Joint Venture Subsidiary, (ii) is not subject (nor are any equity interests in
such Property that are owned directly or indirectly by Borrower, EOPT or any
Joint Venture Parent subject) to a Lien which secures Indebtedness of any
Person, other than Permitted Liens, and (iii) is not subject (nor are any equity
interests in such Property that are owned directly or indirectly by Borrower,
EOPT or Joint Venture Parent subject) to any Negative Pledge. All of the
information set forth on Schedule 1.1 is true and correct in all material
respects.

                  SECTION IV.27. Tax Shelter Regulations. Borrower does not
intend to treat the Loans as being a "reportable transaction" (within the
meaning of Treasury Regulation Section 1.6011-4). In the event Borrower
determines to take any action inconsistent with such intention, it will promptly
notify the Administrative Agent thereof. If Borrower so notifies the
Administrative Agent, Borrower acknowledges that one or more of the Banks may
treat its Committed Loans, Money Market Loans and/or its interest in Swingline
Loans as part of a transaction that is subject to Treasury Regulation Section
301.6112-1, and such Bank or Banks, as applicable, will maintain the lists and
other records required by such Treasury Regulation.

                                    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
related consolidated statements of Borrower's and EOPT's operations and

the chief financial officer of the Borrower (i) setting forth in reasonable
detail the calculations required to establish whether the Borrower was in

the financial condition and the results of operations of the Borrower on the

of any communication (written or oral), whether from a Governmental Authority,
citizens group, employee or otherwise, that alleges that the Borrower, or any of
the Environmental Affiliates, is not in compliance with applicable Environmental
Laws, and such noncompliance is likely to have a Material Adverse Effect; (ii)
the existence of any Environmental Claim pending against the Borrower or any
Environmental Affiliate and such Environmental Claim is likely to have a
Material Adverse Effect; or (iii) any release, emission, discharge or disposal
of any Material of Environmental Concern that is likely to form the basis of any

                                       57

<PAGE>

Borrower or any Environmental Affiliate which in any such event is likely to
have a Material Adverse Effect;

                  (i)      promptly and in any event within five (5) Business
Days after receipt of any notices or correspondence from any company or agent
for any company providing insurance coverage to the Borrower relating to any
loss which is likely to result in a Material Adverse Effect, copies of such
notices and correspondence;

                  (j)      promptly after Borrower has notified the
Administrative Agent of any intention by Borrower to treat the Loans as being a
"reportable transaction" (within the meaning of Treasury Regulation Section
1.6011-4), a duly completed copy of IRS Form 8886 or any successor form; and

                  (k)      from time to time such additional information
regarding the financial position or business of the Borrower, EOPT and their
Subsidiaries as the Administrative Agent, at the request of any Bank, may
reasonably request in writing, so long as disclosure of such information could
not result in a violation of, or expose the Borrower, EOPT or their Subsidiaries
to any material liability under, any applicable law, ordinance or regulation or
any agreements with unaffiliated third parties that are binding on the Borrower,
EOPT or any of their Subsidiaries or on any Property of any of them.

                  SECTION V.2. Payment of Obligations. The Borrower, EOPT and
their Consolidated Subsidiaries will pay and discharge, at or before maturity,
all their respective material obligations and liabilities including, without
limitation, any obligation pursuant to any agreement by which it or any of its
properties is bound, in each case where the failure to so pay or discharge such
obligations or liabilities is likely to result in a Material Adverse Effect, and
will maintain in accordance with GAAP, appropriate reserves for the accrual of
any of the same.

                  SECTION V.3.  Maintenance of Property; Insurance; Leases.

                  (a)      The Borrower will keep, and will cause each
Consolidated Subsidiary to keep, all property useful and necessary in its
business, including without limitation its Real Property Assets (for so long as
it constitutes Real Property Assets), in good repair, working order and
condition, ordinary wear and tear excepted, in each case where the failure to so
maintain and repair will have a Material Adverse Effect.

                  (b)      The Borrower shall maintain, or cause to be
maintained, insurance comparable to that described in Section 4.24 hereof with
insurers meeting the qualifications described therein, which insurance shall in
any event not provide for less coverage than insurance customarily carried by
owners of properties similar to, and in the same locations as, Borrower's Real
Property Assets; provided, however, that such coverages and amounts are
available to Borrower at commercially reasonable rates. The Borrower will
deliver to the Administrative Agent upon the reasonable request of the
Administrative Agent from time to time (i) full information as to the insurance
carried, (ii) within five (5) days of receipt of notice from any

                                       58

<PAGE>

insurer a copy of any notice of cancellation or material change in coverage from
that existing on the date of this Agreement and (iii) forthwith, notice of any
cancellation or nonrenewal (without replacement) of coverage by the Borrower.

                  SECTION V.4. Maintenance of Existence. The Borrower and EOPT
each will preserve, renew and keep in full force and effect, its partnership and
trust existence and its respective rights, privileges and franchises necessary
for the normal conduct of business unless the failure to maintain such rights
and franchises does not have a Material Adverse Effect.

                  SECTION V.5. Compliance with Laws. The Borrower and EOPT will,
and will cause their Subsidiaries to, comply in all material respects with all
applicable laws, ordinances, rules, regulations, and requirements of
governmental authorities (including, without limitation, Environmental Laws, and
all zoning and building codes with respect to its Real Property Assets and ERISA
and the rules and regulations thereunder and all federal securities laws) except
where the necessity of compliance therewith is contested in good faith by
appropriate proceedings or where the failure to do so will not have a Material
Adverse Effect or expose Administrative Agent or Banks to any material liability
therefor.

                  SECTION V.6. Inspection of Property, Books and Records. The
Borrower 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
its business and activities in conformity with GAAP, modified as required by
this Agreement and applicable law; and will permit representatives of any Bank
at such Bank's expense to visit and inspect any of its properties, including
without limitation its Real Property Assets, and so long as disclosure of such
information could not result in a violation of, or expose the Borrower, EOPT or
their Subsidiaries to any material liability under, any applicable law,
ordinance or regulation or any agreements with unaffiliated third parties that
are binding on the Borrower, EOPT or any of their Subsidiaries or on any
Property of any of them, to examine and make abstracts from any of its books and
records and to discuss its affairs, finances and accounts with its officers and
independent public accountants, all at such reasonable times during normal
business hours, upon reasonable prior notice and as often as may reasonably be
desired. Administrative Agent shall coordinate any such visit or inspection to
arrange for review by any Bank requesting any such visit or inspection.

                  SECTION V.7. Existence. The Borrower shall do or cause to be
done, all things necessary to preserve and keep in full force and effect its,
EOPT's and their Consolidated Subsidiaries' existence and its patents,
trademarks, servicemarks, tradenames, copyrights, franchises, licenses, permits,
certificates, authorizations, qualifications, accreditation, easements, rights
of way and other rights, consents and approvals the nonexistence of which is
likely to have a Material Adverse Effect.

                  SECTION V.8.  Financial Covenants.

                  (a)      Total Liabilities to Total Asset Value. The Borrower
shall not permit the ratio of Total Liabilities to Total Asset Value of Borrower
to exceed 0.55:1 at any time.

                                       59

<PAGE>

                  (b)      EBITDA to Interest Expense Ratio. Borrower shall not
permit the ratio of EBITDA for the then most recently completed Fiscal Quarter
to Interest Expense for the then most recently completed Fiscal Quarter to be
less than 2.00:1.

                  (c)      [Intentionally Omitted.]

                  (d)      Cash Flow to Fixed Charges Ratio. Borrower shall not
permit the ratio of Cash Flow for the then most recently completed Fiscal
Quarter to Fixed Charges for the then most recently completed Fiscal Quarter to
be less than 1.5:1.

                  (e)      Secured Debt to Total Asset Value. Borrower shall not
permit the ratio of Secured Debt to Total Asset Value of Borrower to exceed
0.40:1 at any time.

                  (f)      Unencumbered Pool. Borrower shall not permit the
ratio of the outstanding Unsecured Debt to Unencumbered Asset Value to exceed
0.55:1 at any time.

                  (g)      Unencumbered Net Operating Income to Unsecured Debt
Service. Borrower shall not permit the ratio of Unencumbered Net Operating
Income for the then most recently completed Fiscal Quarter to Unsecured Debt
Service for the then most recently completed Fiscal Quarter to be less than
2.0:1.

                  (h)      Minimum Tangible Net Worth. The Consolidated Tangible
Net Worth of the Borrower determined in conformity with GAAP will at no time be
less than the sum of (i) $10,700,000,000, and (ii) seventy percent (70%) of all
Net Offering Proceeds (other than Net Offering Proceeds as a result of the
issuance or offering of any secured or unsecured note, bond or debt instrument)
received by EOPT or Borrower after December 31, 2002 (other than proceeds
received within ninety (90) days after the redemption, retirement or repurchase
of ownership or equity interests in Borrower or Guarantor, up to the amount paid
by Borrower or Guarantor in connection with such redemption, retirement or
repurchase, where, for the avoidance of doubt, the net effect is that neither
Borrower nor Guarantor shall have increased its Net Worth as a result of any
such proceeds).

                  (i)      Dividends. The Borrower will not, as determined on an
aggregate annual basis, pay any partnership distributions in excess of 90% of
the Borrower's FFO for such year. During the continuance of a monetary Event of
Default, Borrower shall only pay partnership distributions that are necessary to
enable EOPT to make those dividends necessary to maintain EOPT's status as a
real estate investment trust.

                  (j)      Permitted Holdings. Borrower's primary business will
be the ownership, operation and development of Office Properties and Parking
Properties and any other business activities of Borrower and its Subsidiaries
will remain incidental thereto. Notwithstanding the foregoing, Borrower and its
Subsidiaries may acquire or maintain Permitted Holdings if and so long as the
aggregate value of Permitted Holdings, whether held directly or indirectly by

                                       60

<PAGE>

Borrower does not exceed, at any time, twenty-five percent (25%) of Total Asset
Value of Borrower unless a greater percentage is approved by the Majority Banks
(which approval shall not be unreasonably withheld, conditioned or delayed);
provided, however, Borrower and its Subsidiaries may not acquire or maintain (i)
Unimproved Assets if and to the extent that the aggregate value of Unimproved
Assets, whether held directly or indirectly by Borrower, exceeds, at any time
ten percent (10%) of Total Asset Value of Borrower or (ii) interests in Taxable
REIT Subsidiaries if and to the extent that the aggregate value of interests in
Taxable REIT Subsidiaries, whether held directly or indirectly by Borrower
exceeds, at any time, twenty percent (20%) of Total Asset Value of Borrower
unless, in either case, a greater percentage is approved by the Majority Banks
(which approval shall not be unreasonably withheld, conditioned or delayed). For
purposes of calculating the foregoing percentage the value of Unimproved Assets
and interests in Taxable REIT Subsidiaries shall be calculated based upon the
lower of the cost thereof and value, determined in accordance with GAAP;
provided that, in the case of any Unimproved Assets held by an Investment
Affiliate, only Borrower's Share of the cost or value of such Unimproved Assets
shall be used in calculating the foregoing percentages.

                  (k)      No Liens. Borrower and EOPT shall not, and shall not
allow any of their Subsidiaries, Financing Partnerships or Joint Venture
Subsidiaries to, allow any Qualifying Unencumbered Property (or any equity
interests in such Property that are owned directly or indirectly by Borrower,
EOPT or any Joint Venture Parent), that is necessary to comply with the
provisions of Sections 5.8(f) and (g) hereof, to become subject to a Lien that
secures the Indebtedness of any Person, other than Permitted Liens or Liens
securing obligations under the Existing Revolver Credit Agreement.

                  (l)      Calculation. Each of the foregoing ratios and
financial requirements shall be calculated as of the last day of each Fiscal
Quarter.

                  SECTION V.9.  Restriction on Fundamental Changes.

                  (a)      Neither the Borrower nor EOPT shall enter into any
merger or consolidation without obtaining the prior written consent thereto in
writing of the Majority Banks, which consent shall not be unreasonably withheld,
conditioned or delayed, unless (i) the Borrower or EOPT is the surviving entity,
(ii) the entity which is merged into Borrower or EOPT is predominantly in the
commercial real estate business, (iii) the creditworthiness of the surviving
entity's long term unsecured debt or implied senior debt, as applicable, is not
lower than Borrower's or EOPT's creditworthiness two months immediately
preceding such merger, and (iv) the then fair market value of the assets of the
entity which is merged into the Borrower or EOPT is less than twenty-five
percent (25%) of the Borrower's or EOPT's then Total Asset Value following such
merger. Neither the Borrower nor EOPT shall liquidate, wind-up or dissolve (or
suffer any liquidation or dissolution), discontinue its business or convey,
lease, sell, transfer or otherwise dispose of, in one transaction or series of
transactions, all or substantially all of its business or property, whether now
or hereafter acquired. Nothing in this Section shall be deemed to prohibit the
sale or leasing of portions of the Real Property Assets in the ordinary course
of business.

                                       61

<PAGE>

                  (b)      The Borrower shall not amend its agreement of limited
partnership or other organizational documents in any manner that would have a
Material Adverse Effect without the Majority Banks' consent, which shall not be
unreasonably withheld, conditioned or delayed. Without limitation of the
foregoing, no Person shall be admitted as a general partner of the Borrower
other than EOPT. EOPT shall not amend its declaration of trust, by-laws, or
other organizational documents in any manner that would have a Material Adverse
Effect without the Majority Banks' consent, which shall not be unreasonably
withheld, conditioned or delayed. The Borrower shall not make any "in-kind"
transfer of any of its property or assets to any of its constituent partners if
such transfer would result in an Event of Default under Section 6.1(b) by reason
of a breach of the provisions of Section 5.8.

                  (c)      Subject to the provisions of clause (b) above, the
Borrower shall deliver to Administrative Agent copies of all amendments to its
agreement of limited partnership or to EOPT's declaration of trust, by-laws, or
other organizational documents no less than ten (10) days after the effective
date of any such amendment.

                  SECTION V.10.  Changes in Business.

                  (a)      Except for Permitted Holdings, neither the Borrower
nor EOPT shall enter into any business which is substantially different from
that conducted by the Borrower or EOPT on the Closing Date after giving effect
to the transactions contemplated by the Loan Documents. The Borrower shall carry
on its business operations through the Borrower, its Consolidated Subsidiaries
and its Investment Affiliates.

                  (b)      Except for Permitted Holdings, Borrower shall not
engage in any line of business other than ownership, operation and development
of Office Properties and Parking Properties and the provision of services
incidental thereto, whether directly or through its Consolidated Subsidiaries
and Investment Affiliates.

                  SECTION V.11.  EOPT Status.

                  (a)      Status. EOPT shall at all times (i) remain a publicly
traded company listed for trading on the New York Stock Exchange, and (ii)
maintain its status as a self-directed and self-administered real estate
investment trust under the Code.

                  (b)      Indebtedness. EOPT shall not, directly or indirectly,
create, incur, assume or otherwise become or remain directly or indirectly
liable with respect to, any Indebtedness, except:

                           (1)      the Obligations; and

                                       62

<PAGE>

                           (2)      Indebtedness of Borrower for which there is
         recourse to EOPT which, after giving effect thereto, may be incurred or
         may remain outstanding without giving rise to an Event of Default or
         Default under any provision of this Article V.

                  (c)      Restriction on Fundamental Changes.

                           (1)      EOPT shall not have an investment in any
         Person other than (i) Borrower or indirectly through Borrower, (ii)
         directly or indirectly in Financing Partnerships, and (iii) the
         interests identified on Schedule 5.11(c)(1) as being owned by EOPT.

                           (2)      EOPT shall not acquire an interest in any
         Property other than (i) securities issued by Borrower, Financing
         Partnerships and Persons formed solely for the purpose of holding
         EOPT's indirect investments in Financing Partnerships and (ii) the
         interests identified on Schedule 5.11(c)(2) attached hereto.

                           (3)      Neither of EOP-QRS Trust nor EOP-QRS LaJolla
         Trust shall have any investments or own any assets other than (i) the
         interests in the Financing Partnerships identified on Schedule
         5.11(c)(3) as being owned by EOP-QRS Trust or EOP-QRS LaJolla Trust and
         (ii) investments in Financing Partnerships that EOPT is permitted to
         own pursuant to Section 5.11(c)(1).

                  (d)      Environmental Liabilities. Neither EOPT nor any of
its Subsidiaries shall become subject to any Environmental Claim which has a
Material Adverse Effect, including, without limitation, any arising out of or
related to (i) the release or threatened release of any Material of
Environmental Concern into the environment, or any remedial action in response
thereto, or (ii) any violation of any Environmental Laws. Notwithstanding the
foregoing provision, EOPT shall have the right to contest in good faith any
claim of violation of an Environmental Law by appropriate legal proceedings and
shall be entitled to postpone compliance with the obligation being contested as
long as (i) no Event of Default shall have occurred and be continuing, (ii) EOPT
shall have given Administrative Agent prior written notice of the commencement
of such contest, (iii) noncompliance with such Environmental Law shall not
subject EOPT or such Subsidiary to any criminal penalty or subject
Administrative Agent or any Bank to pay any civil penalty or to prosecution for
a crime, and (iv) no portion of any Property material to Borrower or its
condition or prospects shall be in substantial danger of being sold, forfeited
or lost, by reason of such contest or the continued existence of the matter
being contested.

                  (e)      Disposal of Partnership Interests. EOPT will not
directly or indirectly convey, sell, transfer, assign, pledge or otherwise
encumber or dispose of any of its partnership interests in Borrower or any of
its equity interest in any of the partners of the Borrower as of the date hereof
(except in connection with the dissolution or liquidation of such partners of
the Borrower), except for the reduction of EOPT's interest in the Borrower
arising from Borrower's

allow any of their Subsidiaries, Financing Partnerships or Joint Venture
Subsidiaries that own, directly or indirectly, any Qualifying Unencumbered
Property to directly or indirectly create, incur, assume or otherwise become or
remain liable with respect to any Indebtedness other than trade debt incurred in
the ordinary course of business, Indebtedness owing to Borrower and obligations
under the Existing Revolving Credit Facility, if the resulting failure of such
Property to qualify as a Qualifying Unencumbered Property would result in an
Event of Default under Section 5.8.

                  SECTION V.13. Forward Equity Contracts. If Borrower shall
enter into any forward equity contracts, Borrower may only settle the same by
delivery of stock, it being agreed that if Borrower shall settle the same with
cash, the same shall constitute an Event of Default hereunder.

for 30 days after written notice thereof has been given to the Borrower by the
Administrative Agent, or if such default is of such a nature that it cannot with
reasonable effort be completely remedied within said period of thirty (30) days
such additional period of time as may be reasonably necessary to cure same,
provided Borrower commences such cure within said thirty (30) day period and
diligently prosecutes same, until completion, but in no event shall such

indebtedness or to permit (without any further requirement of notice or lapse of
time) the holder or holders thereof, or any trustee or agent for such holders,
to accelerate the maturity of any such indebtedness;

                  (f)      the Borrower or EOPT shall commence a voluntary case
or other proceeding seeking liquidation, reorganization or other relief with

bankruptcy laws as now or hereafter in effect;

                  (h)      one or more final, non-appealable judgments or
decrees in an aggregate amount of Twenty Million Dollars ($20,000,000) or more
shall be entered by a court or courts of competent jurisdiction against EOPT,

its Consolidated Subsidiaries (other than any judgment as to which, and only to
the extent, a reputable insurance company has acknowledged coverage of such
claim in

be continuing and in the case of a liability with respect to a Termination Event
which is or could be a liability of the Borrower or EOPT rather than a liability

$10,000,000 and which the Administrative Agent reasonably determines will have a
Material Adverse Effect;

                  (m)      if, any member of the ERISA Group shall commit a

obligations under the EOPT Guaranty;

<PAGE>

                  (p)      any assets of Borrower shall constitute "assets"
(within the meaning of ERISA or Section 4975 of the Code, including but not
limited to 29 C.F.R. ss. 2510.3-101 or any successor regulation thereto) of an
"employee benefit plan" within the meaning of Section 3(3) of ERISA or a "plan"
within the meaning of Section 4975(e)(1) of the Code; or

                  (q)      the Note, the Loan, the Obligations, the EOPT
Guaranty or any of the Loan Documents or the exercise of any of the
Administrative Agent's or any of the Bank's rights in connection therewith shall
constitute a prohibited transaction under ERISA and/or the Code.

                  SECTION VI.2.  Rights and Remedies.

                  (a)      Upon the occurrence of any Event of Default described
in Sections 6.1(f), (g), (p) or (q), the Commitments and the 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,
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 that the Commitments
are terminated and declare the unpaid principal amount of and any and all
accrued and unpaid interest on the Loans and any and all accrued fees and other
Obligations hereunder to be, and the same shall thereupon be, immediately due
and payable with all additional interest from time to time accrued thereon and
(except as otherwise 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 Administrative 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 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.

<PAGE>

                  SECTION VI.3. Notice of Default. The Administrative Agent
shall give notice to the Borrower under Section 6.1(c) and 6.1(d) 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 referring to this
Agreement or the other Loan Documents, describing such event or 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 VI.4.  [Intentionally Omitted].

                  SECTION VI.5. Distribution of Proceeds after Default.
Notwithstanding anything contained herein to the contrary but subject to the
provisions of Section 9.16 hereof, 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 (giving effect to any participations granted therein pursuant to
Section 2.3 and Section 9.4).

                                   ARTICLE VII

                                   THE AGENTS

                  SECTION VII.1. Appointment and Authorization. Each Bank
irrevocably appoints and authorizes the Administrative Agent and the Syndication
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 and the Syndication 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, the Syndication 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 and the Syndication Agent shall each act solely as an agent
of the Banks and do 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 VII.2. Agency and Affiliates. JPMorgan Chase Bank
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 JPMorgan Chase Bank, and its affiliates may accept
deposits from, lend money to, and generally engage in any kind of business with
the Borrower, EOPT or any Subsidiary or affiliate of the Borrower as if they
were

                                       68

<PAGE>

not the Administrative Agent and Syndication Agent, respectively, hereunder, and
the term "Bank" and "Banks" shall include JPMorgan Chase Bank, in its individual
capacities.

                  SECTION VII.3. Action by Administrative Agent and Syndication
Agent. The obligations of the Administrative Agent and Syndication Agent
hereunder are only those expressly set forth herein. Without limiting the
generality of the foregoing, the Administrative Agent and Syndication 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 and Syndication Agent shall be administrative in nature.
Subject to the provisions of Sections 7.1, 7.5 and 7.6, Administrative Agent
shall use the same care in the administration of the Loans in the same manner as
Administrative Agent uses in the administration of its own loans.

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

                  SECTION VII.5. Liability of Administrative Agent. As between
Administrative Agent on the one hand and the Banks on the other hand, none of
the Administrative Agent nor any of its affiliates nor any Agent-Related Person,
shall be liable for any action taken or not taken by it in connection herewith
(i) with the consent or at the request of the Required Banks or (ii) in the
absence of its own gross negligence or willful misconduct. As between
Administrative Agent on the one hand and the Banks on the other hand, none of
the Administrative Agent nor any Agent-Related Person, shall be responsible for
or have any duty to ascertain, inquire into or verify: (i) any statement,
warranty or representation made in connection with this Agreement or any
borrowing hereunder; (ii) the performance or observance of any of the covenants
or agreements of the Borrower; (iii) the satisfaction of any condition specified
in Article III, except receipt of items required to be delivered to the
Administrative Agent; or (iv) the validity, effectiveness or genuineness of this
Agreement, the other Loan Documents or any other instrument or writing furnished
in connection herewith. As between Administrative Agent and the Agent-Related
Persons on the one hand and the Banks on the other hand, neither the
Administrative Agent nor the Agent-Related Persons shall incur any liability by
acting in reliance upon any notice, consent, certificate, statement, or other
writing (which may be a bank wire, telex or similar writing) believed by it to
be genuine or to be signed by the proper party or parties.

                  SECTION VII.6. Indemnification. Each Bank shall, ratably in
accordance with its Commitment, indemnify the Administrative Agent and each
Agent-Related Person and their affiliates and its directors, officers, agents
and employees (to the extent not reimbursed by the Borrower) against any cost,
expense (including, without limitation, counsel fees and disbursements), claim,
demand, action, loss or liability (except such as result from such indemnitee's
gross negligence or willful misconduct) that such indemnitee may suffer or incur
in

                                       69

<PAGE>

connection with its duties as Administrative Agent under this Agreement, the
other Loan Documents or any action taken or omitted by such indemnitee
hereunder. In the event that the Administrative Agent or any Agent-Related
Person 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, the
Administrative Agent or such Agent-Related Person 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 Administrative Agent or such
Agent-Related Person shall reimburse such Banks so entitled to reimbursement
within two (2) Business Days of its receipt of such funds from the Borrower or
such other party liable therefor.

                  SECTION VII.7. Credit Decision. Each Bank acknowledges that it
has, independently and without reliance upon the Administrative Agent, the
Syndication Agent or any other Bank or Agent-Related Person, 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,
the Syndication Agent or any other Bank or Agent-Related Person, and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking any action
under this Agreement.

                  SECTION VII.8. Successor Administrative Agent 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. In addition,
the Administrative Agent or the Syndication Agent, as applicable, shall resign
in the event its Commitment (without participations) is reduced to less than
Thirty Million Dollars ($30,000,000), in the case of the Administrative Agent,
or Twenty-Five Million Dollars ($25,000,000), in the case of the Syndication
Agent, unless as a result of a cancellation or reduction in the aggregate
Commitments. In addition, if the Administrative Agent shall so resign, then it
shall also resign as the Swingline Lender. Upon any such resignation, the
Majority Banks shall have the right to appoint a successor Administrative Agent
and Swingline Lender or Syndication Agent, as applicable, which successor
Administrative Agent and Swingline Lender 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, conditioned or delayed (except that Borrower shall, in
all events, be deemed to have approved Citicorp North America, Inc., as a
successor Administrative Agent or as a successor Swingline Lender). If no
successor Administrative Agent and Swingline Lender or Syndication Agent (as
applicable) shall have been so appointed by the Majority Banks and approved by
the Borrower, and shall have accepted such appointment, within 30 days after the
retiring Administrative Agent and Swingline Lender 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 Administrative Agent and Swingline Lender or the Syndication
Agent as the case may be, who shall act until the Majority Banks shall appoint
an Administrative Agent and Swingline Lender or Syndication Agent. Any
appointment of a successor Administrative Agent and Swingline Lender

                                       70

<PAGE>

or Syndication Agent by Majority Banks or the retiring Administrative Agent and
Swingline Lender or the Syndication Agent pursuant to the preceding sentence
shall, provided no Event of Default has occurred and is then continuing, be
subject to the Borrower's approval, which approval shall not be unreasonably
withheld, conditioned or delayed. Upon the acceptance of its appointment as the
Administrative Agent and Swingline Lender or Syndication Agent hereunder by a
successor Administrative Agent and Swingline Lender or successor Syndication
Agent, as applicable, such successor Administrative Agent and Swingline Lender,
or successor Syndication Agent, as applicable, shall thereupon succeed to and
become vested with all the rights and duties of the retiring Administrative
Agent and Swingline Lender or retiring Syndication Agent, as applicable, and the
retiring Administrative Agent and Swingline Lender 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 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) 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 VII.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) 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 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, Majority 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, Majority Banks or all the Banks (and

                                       71

<PAGE>

each non-responding Bank shall be deemed to have concurred with such recommended
course of action), as the case may be.

                                  ARTICLE VIII

                             CHANGE IN CIRCUMSTANCES

                  SECTION VIII.1. Basis for Determining Interest Rate Inadequate
or Unfair. If on or prior to the first day of any Interest Period for any
Euro-Dollar Borrowing or Money Market IBOR Loan the Administrative Agent
determines in good faith that deposits in dollars (in the applicable amounts)
are not being offered in the relevant market 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 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 IBOR
Borrowing for which a Notice of Money Market Borrowing has previously been
given, the Money Market IBOR Loans comprising such Borrowing shall bear interest
for each day from and including the first day to but excluding the last day of
the Interest Period applicable thereto at the Base Rate for such day.

                  SECTION VIII.2. Illegality. If, 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) to make, maintain or fund its
Euro-Dollar Loans, the Administrative Agent shall forthwith give notice thereof
to the other Banks and the Borrower, whereupon until such Bank notifies the
Borrower and the Administrative Agent that the circumstances giving rise to such
suspension no longer exist, the obligation of such Bank to make Euro-Dollar
Loans 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

                                       72

<PAGE>

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) 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 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 canceled pursuant to Section 2.11(e).

                  SECTION VIII.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 each case, the "Loan Effective Date"), 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), 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 interbank market any other condition
materially more burdensome in nature, extent or consequence than those in
existence as of the Loan Effective 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

                                       73

<PAGE>

by any Governmental Authority, central bank or comparable agency charged with
the interpretation or administration thereof, or any request or directive
regarding capital adequacy (whether or not having the force of law) 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 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 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)
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 canceled pursuant to Section 2.11(e).

                  SECTION VIII.4. Taxes.

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

                                       74

<PAGE>

of each Bank and the Administrative Agent, taxes imposed on its income, and
franchise taxes imposed on it, by the jurisdiction under the laws of which such
Bank or the Administrative Agent (as the case may be) is organized or any
political subdivision thereof and, in the case of each Bank, taxes imposed on
its income, and franchise or similar taxes imposed on it, by the jurisdiction of
such Bank's Applicable Lending Office or any political subdivision thereof 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, (i) the sum payable shall be increased as
necessary so that after making all required deductions (including, without
limitation, deductions applicable to additional sums payable under this Section
8.4) such 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 from the execution or delivery of, or otherwise with respect to,
this Agreement or any Note (hereinafter referred to as "Other Taxes").

                  (c)      The Borrower agrees to indemnify each 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 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
respect thereto. This indemnification shall be made within 15 days from the date
such 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 any successor form prescribed by the Internal
Revenue Service, and (B) an Internal Revenue Service Form W-8BEN or W-8ECI, as
appropriate, 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, that such Bank is entitled to benefits under an income
tax treaty to which the United

                                       75
<PAGE>

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 being under Sections 1442(c)(1) and 1442(a) of
the Internal Revenue Code, 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.

                  (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)
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 canceled pursuant to Section 2.11(c).

                  SECTION VIII.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 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:

                                       76
<PAGE>

                  (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 IX.1. Notices. All notices, requests and other
communications to any party hereunder shall be in writing (including bank wire,
telex, facsimile transmission followed by telephonic confirmation or similar
writing) and shall be given to such party: (x) in the case of the Borrower, the
Syndication Agent or the Administrative Agent, at its address, telex number or

appropriate answerback or facsimile confirmation is received, (ii) if given by
certified registered mail, return receipt requested, with first class postage
prepaid, addressed as aforesaid, upon receipt or refusal to accept delivery,
(iii) if given by a nationally recognized overnight carrier, 24 hours after such
communication is deposited with such carrier with postage prepaid for next day

specified in this Section; provided that notices to the Administrative Agent
under Article II or Article VIII shall not be effective until received.

                  SECTION IX.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

                                       77
<PAGE>

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 IX.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 (including, without limitation,
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
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, without limitation, fees and
disbursements of counsel for the Administrative Agent and each of the Banks, in
connection with the enforcement of the Loan Documents and the instruments
referred to therein and such Event of Default and collection, bankruptcy,
insolvency and other enforcement proceedings resulting therefrom; 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 Administrative Agent).

                  (b)      The Borrower agrees to indemnify the Administrative
Agent and each Bank, their respective affiliates and the respective directors,
officers, agents and employees of the foregoing (each an "Indemnitee") and hold
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
or the Environmental Affiliates of any applicable Environmental Law, (iii) any
Environmental Claim arising out of the management, use, control, ownership or
operation of property or assets by the Borrower or any of the Environmental
Affiliates, including, without limitation, all on-site and off-site activities
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

                                       78
<PAGE>

compensated pursuant to the terms of this Agreement, (b) incurred solely by
reason of the gross negligence, willful misconduct bad faith or fraud of any
Indemnitee as finally determined by a court of competent jurisdiction, (c)
arising from 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) owing by 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 employee of Administrative Agent or any Bank shall be solely
in their respective capacities 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. Without limitation of the other
provisions of this Section 9.3, Borrower shall indemnify and hold each of the
Administrative Agent and the Banks free and harmless from and against all loss,
costs (including reasonable attorneys' fees and expenses), expenses, taxes, and
damages (including consequential damages) that the Administrative Agent and the
Banks may suffer or incur by reason of the investigation, defense and settlement
of claims and in obtaining any prohibited transaction exemption under ERISA or
the Code necessary in the Administrative Agent's reasonable judgment by reason
of the inaccuracy of the representations and warranties, or a breach of the
provisions, set forth in Section 4.6(b).

                  SECTION IX.4. Sharing of Set-Offs. In addition to any rights
now or hereafter granted under applicable law or otherwise, and not by way of
limitation of any such rights, upon the occurrence and during the continuance of
any Event of Default, each Bank is hereby authorized at any time or from time to
time, without presentment, demand, protest or other notice of any kind to the
Borrower or to any other Person, any such notice being hereby expressly waived,
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, the Bank
receiving such proportionately greater payment shall purchase such
participations in the Notes held by the other Banks, and such other adjustments
shall be made, as may be required so that all such payments of principal and
interest with respect to the Notes held by the Banks shall be shared by the
Banks pro rata; provided that nothing in this Section shall impair the right of
any Bank to exercise any right of set-off or counterclaim it may have 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. The Borrower agrees, to the fullest
extent it may effectively do so under applicable law, that any holder of a
participation in a Note, whether or not acquired pursuant to the foregoing
arrangements, may exercise rights of set-off or counterclaim and other rights
with respect to such participation as fully as if such holder of a participation
were a direct creditor of the Borrower in the amount of

                                       79
<PAGE>

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

                  SECTION IX.5. Amendments and Waivers. Any provision of this
Agreement or the Notes or other Loan Documents may be amended or waived if, but
only if, such amendment or waiver is in writing and is signed by the Borrower
and the Majority Banks (and, if the rights or duties of the Administrative Agent
or the Swingline Lender in their capacity as Administrative Agent or the
Swingline Lender, as applicable, are affected thereby, by the Administrative
Agent or the Swingline Lender, as applicable); provided that (A) no amendment or
waiver of the provisions of Article V (including, without limitation, any of the
definitions of the defined terms used in Section 5.8 hereof) shall be effective
unless signed by the Borrower and the Required Banks and (B) no such amendment
or waiver with respect to this Agreement, the Notes 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 beyond the
Maturity Date, (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 EOPT Guaranty or (vi)
modify the provisions of this Section 9.5.

                  SECTION IX.6.  Successors and Assigns.

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

                  (b)      Prior to the occurrence of an Event of Default, any
Bank may at any time, from and after the date that is six (6) months after the
Closing Date, with (and subject to) the consent of Borrower (which consent shall
not be unreasonably withheld, conditioned or delayed), grant to an existing
Bank, one or more banks, finance companies, insurance companies or other
financial institutions (a "Participant") in minimum amounts of not less than
$5,000,000 (or any lesser amount in the case of participations to an existing
Bank) participating interests in its Commitment or any or all of its Loans.
After the occurrence and during the continuance of an Event of Default, any Bank
may at any time grant to any Person in any amount (also a "Participant"),
participating interests in its Commitment or any or all of its Loans.
Notwithstanding anything to the contrary in this subsection (b), with respect to
a Bank's granting of participations in its outstanding Money Market Loans prior
to the occurrence of an Event of Default, the minimum amount of such
participations shall be $5,000,000 and no consent of the

                                       80
<PAGE>

Administrative Agent or the Borrower shall be required. 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.

                  (c)      Any Bank may assign to a Qualified Institution (in
each case, an "Assignee") (i) prior to the occurrence of an Event of Default and
from and after the date that is six (6) months after the Closing Date, in
minimum amounts of not less than Five Million Dollars ($5,000,000) and integral
multiple 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, in any amount, 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; provided, that if no Event of Default shall have occurred and
be continuing, such assignment shall be subject to the Administrative Agent's
and the Borrower's consent, which consent shall not be unreasonably withheld,
conditioned or delayed; and provided further that if an Assignee is an affiliate
of such transferor Bank and is an Affiliate Qualified Institution, or was a Bank
immediately prior to such assignment, no such consent shall be required; and
provided further that such assignment may, but need 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

                                       81
<PAGE>

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 Lead Agent for
its acceptance a Designation Agreement. Upon such receipt of an appropriately
completed Designation Agreement executed by a Designating Lender and a designee
representing that it is a Designated Lender, the Lead 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 2.4(b)) to make Money Market Loans on behalf of its
Designating Lender pursuant to Section 2.4 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, the Senior Managing Agents, the Managing Agents, the
Co-Agents and the Banks for each and every one 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, the Senior Managing Agents, the Managing Agents, the
Co-Agents and the Banks may rely thereon without any requirement that the
Designated Lender sign or acknowledge the same. No Designated Lender may assign
or transfer all or any portion of its interest hereunder or under any other Loan
Document, other than assignments to the Designating Lender which originally
designated such Designated Lender or otherwise in accordance with the provisions
of Section 9.6 (b) and (c).

<PAGE>

                  (e)      Any Bank may at any time assign all or any portion of
its rights under this Agreement and its Note to a Federal Reserve Bank. No such
assignment shall release the transferor Bank from its obligations hereunder.

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

                  (g)      No Assignee of any rights and obligations under this
Agreement shall be permitted to further assign less than all of such rights and
obligations. No participant in any rights and obligations under this Agreement
shall be permitted to sell subparticipations of such rights and obligations.

                  (h)      Anything in this Agreement to the contrary
notwithstanding, so long as no Event of Default shall have occurred and be
continuing, no Bank shall be permitted to enter into an assignment of, or sell a
participation interest in, its rights and obligations hereunder which would
result in such Bank holding a Commitment without participants of less than Five
Million Dollars ($5,000,000) (or in the case of the Administrative Agent, Thirty
Million Dollars ($30,000,000)) unless as a result of a cancellation or reduction
of the aggregate Commitments; provided, however, that no Bank shall be
prohibited from assigning its entire Commitment so long as such assignment is
otherwise permitted under this Section 9.6.

                  SECTION IX.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 IX.8.  Governing Law; Submission to Jurisdiction.

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

                  (b)      Any legal action or proceeding with respect to this
Agreement or any other Loan Document and any action for enforcement of any
judgment in respect thereof may be brought in the courts of the State of New
York or of the United States of America for the Southern District of New York,
and, by execution and delivery of this Agreement, the Borrower hereby accepts
for itself and in respect of its property, generally and unconditionally, the
non-exclusive jurisdiction of the aforesaid courts and appellate courts from any
thereof. The

                                       83
<PAGE>

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 IX.9. Counterparts; Integration;. Effectiveness. This
Agreement may be signed in any number of counterparts, each of which shall be an
original, with the same effect as if the signatures thereto and hereto were upon
the same instrument. This 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, telex or other written confirmation from such party of
execution of a counterpart hereof by such party).

                  SECTION IX.10. WAIVER OF JURY TRIAL. EACH OF THE BORROWER, THE
ADMINISTRATIVE AGENT, THE SYNDICATION AGENT AND THE BANKS HEREBY IRREVOCABLY
WAIVE ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF
OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

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

                  SECTION IX.12. Domicile of Loans. Each Bank may transfer and
carry its Loans at, to or for the account of any domestic or foreign branch
office, subsidiary or affiliate of such Bank.

                  SECTION IX.13. Limitation of Liability. No claim may be made
by the Borrower or any other Person acting by or through Borrower against the
Administrative Agent, the Syndication Agent or any Bank or the affiliates,
directors, officers, employees, attorneys or agent of any of them for any
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

                                       84
<PAGE>

claim for any such damages, whether or not accrued and whether or not known or
suspected to exist in its favor.

                  SECTION IX.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 (i) any officer, director,
shareholder or employee of the Borrower or EOPT or (ii) any general partner of
Borrower other than EOPT, in each case except in the event of fraud or
misappropriation of funds on the part of such officer, director, shareholder or
employee or such general partner.

                  SECTION IX.15. Confidentiality. The Administrative Agent and
each Bank shall use reasonable efforts to assure that information about
Borrower, EOPT 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 and other transactions between such Bank and the Borrower, 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 confidentiality agreement substantially equivalent to the terms of
this Section 9.15, and (d) as may otherwise be required or requested by any
regulatory authority having jurisdiction over the Administrative Agent or any
Bank or by any applicable law, rule, regulation or judicial process.
Notwithstanding anything herein to the contrary, "information" shall not
include, and the Administrative Agent and each Bank may disclose without
limitation of any kind, any information with respect to the "tax treatment" and
"tax structure" (in each case within the meaning of Treasury Regulation Section
1.6011-4) of the transactions contemplated hereby and all materials of any kind
(including opinions and tax analyses) that are provided to the Administrative
Agent or such Bank relating to such tax treatment and tax structure; provided
that with respect to any document or similar item that in either case contains
information concerning the tax treatment or tax structure of the transaction as
well as other information, this sentence shall only apply to such portion of the
documents or similar item that relate to the tax treatment or tax structure of
the Loans and transactions contemplated hereby. The Administrative Agent and/or
the Bank making any such disclosure shall endeavor to notify Borrower prior to
making any such disclosure of the fact that such disclosure is being made and
the nature of the disclosure. In addition, the Administrative Agent and/or such
Bank shall provide Borrower with a copy of the disclosure promptly after the
same is made.

                  SECTION IX.16.  Bank's Failure to Fund.

                                       85
<PAGE>

                  (a)      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.

                  (b)      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) Business Days after notice
of such failure from Administrative Agent, (y) shall otherwise fail to perform
such Bank's obligations under the Loan Documents (including, without limitation,
the obligation to purchase participations pursuant to Section 2.3) for a period
of five (5) 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) 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
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 monetary 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.

                                       86
<PAGE>

                           (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.

                  (c)      Immediately upon a Bank's becoming a Junior Creditor
and until such time as such Bank shall have cured all applicable defaults, no
Junior Creditor shall, prior to Payment in Full of all Senior Debt:

                           (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.

                  (d)      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 marshaling of the assets of the
Borrower;

                                       87
<PAGE>

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.

                  (e)      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 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.

                  (f)      (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,

                                       88
<PAGE>

be necessary or desirable to assure the effectiveness of the subordination
effected by this Agreement.

                  (g)      (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.

                           (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,
without limitation, 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).

<PAGE>

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

                  (i)      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 or
Majority 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.

                  (j)      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 IX.17. Banks' ERISA Covenant. Each Bank, by its
signature hereto or on the applicable Transfer Supplement, hereby agrees (a)
that on the date any Loan is disbursed hereunder no portion of such Bank's Pro
Rata Share of such Loan will constitute "assets" within the meaning of 29 C.F.R.
ss. 2510.3-101 of an "employee benefit plan" within the meaning of Section 3(3)
of ERISA or a "plan" within the meaning of Section 4975(e)(1) of the Code, and
(b)

                                       90
<PAGE>

that following such date such Bank shall not allocate such Bank's Pro Rata
Share of any Loan to an account of such Bank if such allocation (i) by itself
would cause such Pro Rata Share of such Loan to then constitute "assets" (within
the meaning of 29 C.F.R. ss. 2510.3-101) of an "employee benefit plan" within
the meaning of Section 3(3) of ERISA or a "plan" within the meaning of Section
4975(e)(1) of the Code and (ii) by itself would cause such Loan to constitute a
prohibited transaction under ERISA or the Code (which is not exempt from the
restrictions of Section 406 of ERISA and Section 4975 of the Code and the taxes
and penalties imposed by Section 4975 of the Code and Section 502(i) of ERISA)
or any Agent or Bank being deemed in violation of Section 404 of ERISA.

                  SECTION IX.18.  [Intentionally Omitted]

                  SECTION 9.19. No Bankruptcy Proceedings. Each of the Borrower,
the Banks, the Administrative Agent, the Syndication Agent, the Co-Documentation
Agents 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.

                  SECTION 9.20. Administrative Agent May File Proofs of Claim.
In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to Borrower or any party to the EOPT Guaranty, the
Administrative Agent (irrespective of whether the principal of any Loan shall
then be due and payable as herein expressed or by declaration or otherwise and
irrespective of whether the Administrative Agent shall have made any demand on
Borrower) shall be entitled and empowered, by intervention in such proceeding or
otherwise:

         (a) to file and prove a claim for the whole amount of the principal and
         interest owing and unpaid in respect of the Loans and all other
         Obligations that are owing and unpaid and to file such other documents
         as may be necessary or advisable in order to have the claims of the
         Banks and the Administrative Agent (including any claim for the
         reasonable compensation, expenses, disbursements and advances of the
         Banks and the Administrative Agent and their respective agents and
         counsel and other amounts due the Banks and the Administrative Agent
         hereunder allowed in such judicial proceeding); and

         (b) to collect and receive any monies or other property payable or
         deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Bank to make such payments to the Administrative Agent and, in the event
that the Administrative Agent shall consent to the making of such payments
directly to the Banks, to pay to the Administrative Agent any amount due for

                                       91
<PAGE>

the reasonable compensation, expenses, disbursements and advances of the
Administrative Agent and its agents and counsel and other amounts due the
Administrative Agent hereunder. Nothing contained herein shall be deemed to
authorize the Administrative Agent to authorize or consent to or accept or adopt
on behalf of any Bank any plan of reorganization, arrangement, adjustment or
composition affecting the Obligations or the rights of any Bank or to authorize
the Administrative Agent to vote in respect of the claim of any Bank in any such
proceeding.

same may be amended from time to time, the "Credit Agreement").

                              W I T N E S S E T H:

         WHEREAS, THE BANKS HAVE AGREED TO MAKE LOANS TO BORROWER IN THE
AGGREGATE PRINCIPAL AMOUNT NOT TO EXCEED ONE BILLION DOLLARS ($1,000,000,000)
(HEREINAFTER COLLECTIVELY REFERRED TO AS THE "LOANS");

         WHEREAS, THE LOANS ARE EVIDENCED BY CERTAIN PROMISSORY NOTES (THE
"NOTES") OF BORROWER MADE TO EACH OF THE BANKS IN ACCORDANCE WITH THE TERMS OF
THE CREDIT AGREEMENT;

         WHEREAS, THE CREDIT AGREEMENT AND THE NOTES AND ANY OTHER DOCUMENTS
EXECUTED IN CONNECTION THEREWITH ARE HEREINAFTER COLLECTIVELY REFERRED TO AS THE
"LOAN DOCUMENTS";

         WHEREAS, CAPITALIZED TERMS USED HEREIN AND NOT OTHERWISE DEFINED SHALL
HAVE THE MEANINGS ASCRIBED THERETO IN THE CREDIT AGREEMENT;

         WHEREAS, GUARANTOR IS THE SOLE GENERAL PARTNER OF BORROWER; AND

         WHEREAS, AS A CONDITION TO THE EXECUTION AND DELIVERY OF THE LOAN
DOCUMENTS, THE BANKS HAVE REQUIRED THAT GUARANTOR EXECUTE AND DELIVER THIS
GUARANTY; AND

         NOW THEREFORE, IN CONSIDERATION OF THE PREMISES AND THE BENEFITS TO BE
DERIVED FROM THE MAKING OF THE LOANS BY THE BANKS TO BORROWER, AND IN ORDER TO
INDUCE THE ADMINISTRATIVE AGENT, THE SYNDICATION AGENT, THE CO-DOCUMENTATION
AGENTS, AND THE BANKS TO ENTER INTO THE CREDIT AGREEMENT AND THE OTHER LOAN
DOCUMENTS, THE GUARANTOR HEREBY AGREES AS FOLLOWS:

<PAGE>

         1.       Guarantor, on behalf of itself and its successors and assigns,
hereby irrevocably, absolutely and unconditionally guarantees the full and
punctual payment when due, whether at stated maturity or otherwise, of all
Obligations of Borrower now or hereafter existing under the Notes and the Credit
Agreement, for principal and/or interest as well as any and all other amounts
due thereunder, including, without limitation, all indemnity obligations of
Borrower thereunder, and any and all reasonable costs and expenses (including,
without limitation, reasonable attorneys' fees and disbursements) incurred by
the Administrative Agent, the Syndication Agent, the Co-Documentation Agents, or
the Banks in enforcing their rights under this Guaranty (all of the foregoing
obligations being the "Guaranteed Obligations").

         2.       It is agreed that the Guaranteed Obligations of Guarantor
hereunder are primary and this Guaranty shall be enforceable against Guarantor
and its successors and assigns without the necessity for any suit or proceeding
of any kind or nature whatsoever brought by the Administrative Agent or any of
the Banks against Borrower or its respective successors or assigns or any other
party or against any security for the payment and performance of the Guaranteed
Obligations and without the necessity of any notice of non-payment or
non-observance or of any notice of acceptance of this Guaranty or of any notice
or demand to which Guarantor might otherwise be entitled (including, without
limitation, diligence, presentment, notice of maturity, extension of time,
change in nature or form of the Guaranteed Obligations, acceptance of further
security, release of further security, imposition or agreement arrived at as to
the amount of or the terms of the Guaranteed Obligations, notice of adverse
change in Borrower's financial condition and any other fact which might
materially increase the risk to Guarantor), all of which Guarantor hereby
expressly waives; and Guarantor hereby expressly agrees that the validity of
this Guaranty and the obligations of Guarantor hereunder shall in no way be
terminated, affected, diminished, modified or impaired by reason of the
assertion of or the failure to assert by the Administrative Agent or any of the
Banks against Borrower or its respective successors or assigns, any of the
rights or remedies reserved to the Administrative Agent or any of the Banks
pursuant to the provisions of the Loan Documents. Guarantor agrees that any
notice or directive given at any time to the Administrative Agent or any of the
Banks which is inconsistent with the waiver in the immediately preceding
sentence shall be void and may be ignored by the Administrative Agent and the
Banks, and, in addition, may not be pleaded or introduced as evidence in any
litigation relating to this Guaranty for the reason that such pleading or
introduction would be at variance with the written terms of this Guaranty,
unless the Administrative Agent has specifically agreed otherwise in a writing,
signed by a duly authorized officer. Guarantor specifically acknowledges and
agrees that the foregoing waivers are of the essence of this transaction and
that, but for this Guaranty and such waivers, the Administrative Agent and the
Banks would have declined to execute and deliver the Loan Documents.

         3.       Guarantor waives, and covenants and agrees that it will not at
any time insist upon, plead or in any manner whatsoever claim or take the
benefit or advantage of, any and all appraisal, valuation, stay, extension,
marshalling-of-assets or redemption laws, or right of homestead or exemption,
whether now or at any time hereafter in force, which may delay, prevent or
otherwise affect the performance by Guarantor of its obligations under or the

                                        2
<PAGE>

enforcement by the Administrative Agent or any of the Banks of, this Guaranty.
Guarantor further covenants and agrees not to set up or claim any defense,
counterclaim, offset, setoff or other objection of any kind to any action, suit
or proceeding in law, equity or otherwise, or to any demand or claim that may be
instituted or made by the Administrative Agent or any of the Banks other than
the defense of the actual timely payment and performance by Borrower of the
Guaranteed Obligations hereunder; provided, however, that the foregoing shall
not be deemed a waiver of Guarantor's right to assert any compulsory
counterclaim, if such counterclaim is compelled under local law or rule of
procedure, nor shall the foregoing be deemed a waiver of Guarantor's right to
assert any claim which would constitute a defense, setoff, counterclaim or
crossclaim of any nature whatsoever against Administrative Agent or any Bank in
any separate action or proceeding. Guarantor represents, warrants and agrees
that, as of the date hereof, its obligations under this Guaranty are not subject
to any counterclaims, offsets or defenses against the Administrative Agent or
any Bank of any kind.

                  4.       The provisions of this Guaranty are for the benefit
of the Administrative Agent, the Syndication Agent, the Co-Documentation Agents,
and the Banks and their successors and permitted assigns, and nothing herein
contained shall impair as between Borrower and the Administrative Agent, the
Syndication Agent, the Co-Documentation Agents, and the Banks the obligations of
Borrower under the Loan Documents.

                  5.       This Guaranty shall be a continuing, unconditional
and absolute guaranty and the liability of Guarantor hereunder shall in no way
be terminated, affected, modified, impaired or diminished by reason of the
happening, from time to time, of any of the following, although without notice
or the further consent of Guarantor:

                  (1)      any assignment, amendment, modification or waiver of
         or change in any of the terms, covenants, conditions or provisions of
         any of the Guaranteed Obligations or the Loan Documents or the
         invalidity or unenforceability of any of the foregoing; or

                  (2)      any extension of time that may be granted by the
         Administrative Agent to Borrower, any guarantor, or their respective
         successors or assigns, heirs, executors, administrators or personal
         representatives; or

                  (3)      any action which the Administrative Agent, the
         Syndication Agent, the Co-Documentation Agents, the Arrangers and/or
         the Banks may take or fail to take under or in respect of any of the
         Loan Documents or by reason of any waiver of, or failure to enforce any
         of the rights, remedies, powers or privileges available to the
         Administrative Agent under this Guaranty or available to the
         Administrative Agent, the Syndication Agent, the Co-Documentation
         Agents, the Arrangers and/or the Banks at law, equity or otherwise, or
         any action on the part of the Administrative Agent, the Syndication
         Agent, the Co-Documentation Agents, the Arrangers and/or the Banks
         granting indulgence or extension in any form whatsoever; or

                  (4)      any sale, exchange, release, or other disposition of
         any property pledged,

                                        3
<PAGE>

         mortgaged or conveyed, or any property in which the Administrative
         Agent and/or the Banks have been granted a lien or security interest to
         secure any indebtedness of Borrower to the Administrative Agent and/or
         the Banks; or

                  (5)      any release of any person or entity who may be liable
         in any manner for the payment and collection of any amounts owed by
         Borrower to the Administrative Agent, the Syndication Agent, the
         Co-Documentation Agents, the Arrangers and/or the Banks; or

                  (6)      the application of any sums by whomsoever paid or
         however realized to any amounts owing by Borrower to the Administrative
         Agent, the Syndication Agent, the Co-Documentation Agents, the
         Arrangers and/or the Banks under the Loan Documents in such manner as
         the Administrative Agent shall determine in its sole discretion; or

                  (7)      Borrower's or any guarantor's voluntary or
         involuntary liquidation, dissolution, sale of all or substantially all
         of their respective assets and liabilities, appointment of a trustee,
         receiver, liquidator, sequestrator or conservator for all or any part
         of Borrower's or Guarantor's assets, insolvency, bankruptcy, assignment
         for the benefit of creditors, reorganization, arrangement, composition
         or readjustment, or the commencement of other similar proceedings
         affecting Borrower or any guarantor or any of the assets of any of
         them, including, without limitation, (i) the release or discharge of
         Borrower or any guarantor from the payment and performance of their
         respective obligations under any of the Loan Documents by operation of
         law, or (ii) the impairment, limitation or modification of the
         liability of Borrower or any guarantor in bankruptcy, or of any remedy
         for the enforcement of the Guaranteed Obligations under any of the Loan
         Documents, or Guarantor's liability under this Guaranty, resulting from
         the operation of any present or future provisions of the Bankruptcy
         Code or other present or future federal, state or applicable statute or
         law or from the decision in any court; or

                  (8)      any improper disposition by Borrower of the proceeds
         of the Loans, it being acknowledged by Guarantor that the
         Administrative Agent, the Syndication Agent, the Arrangers, the
         Co-Documentation Agents, or any Bank shall be entitled to honor any
         request made by Borrower for a disbursement of such proceeds and that
         neither the Administrative Agent, the Syndication Agent, the
         Co-Documentation Agents, the Arrangers nor any Bank shall have any
         obligation to see the proper disposition by Borrower of such proceeds.

                  6.       Guarantor agrees that if at any time all or any part
of any payment at any time received by the Administrative Agent from Borrower or
Guarantor under or with respect to this Guaranty is or must be rescinded or
returned by the Administrative Agent, the Syndication Agent, the
Co-Documentation Agents, the Arrangers or any Bank for any reason whatsoever
(including, without limitation, the insolvency, bankruptcy or reorganization of
Borrower or Guarantor), then Guarantor's obligations hereunder shall, to the
extent of the payment rescinded or returned, be deemed to have continued in
existence notwithstanding such previous receipt by

                                        4
<PAGE>

such party, and Guarantor's obligations hereunder shall continue to be effective
or reinstated, as the case may be, as to such payment, as though such previous
payment had never been made.

                  7.       Until this Guaranty is terminated pursuant to the
terms hereof, Guarantor (i) shall have no right of subrogation against Borrower
or any entity comprising same by reason of any payments or acts of performance
by Guarantor in compliance with the obligations of Guarantor hereunder, (ii)
waives any right to enforce any remedy which Guarantor now or hereafter shall
have against Borrower or any entity comprising same by reason of any one or more
payment or acts of performance in compliance with the obligations of Guarantor
hereunder and (iii) from and after an Event of Default (as defined in the Credit
Agreement), subordinates any liability or indebtedness of Borrower or any entity
comprising same now or hereafter held by Guarantor or any affiliate of Guarantor
to the obligations of Borrower under the Loan Documents. The foregoing, however,
shall not be deemed in any way to limit any rights that Guarantor may have
pursuant to the Agreement of Limited Partnership of Borrower or which it may
have at law or in equity with respect to any other partners of Borrower.

                  8.       Guarantor represents and warrants to the
Administrative Agent, the Syndication Agent, the Co-Documentation Agents, the
Arrangers and the Banks with the knowledge that the Administrative Agent, the
Syndication Agent, the Co-Documentation Agents, the Arrangers and the Banks are
relying upon the same, as follows:

                  (1)      as of the date hereof, Guarantor is the sole general
         partner of Borrower;

                  (2)      based upon such relationships, Guarantor has
         determined that it is in its best interests to enter into this
         Guaranty;

                  (3)      this Guaranty is necessary and convenient to the
         conduct, promotion and attainment of Guarantor's business, and is in
         furtherance of Guarantor's business purposes;

                  (4)      the benefits to be derived by Guarantor from
         Borrower's access to funds made possible by the Loan Documents are at
         least equal to the obligations undertaken pursuant to this Guaranty;

                  (5)      Guarantor is solvent and has full power and legal
         right to enter into this Guaranty and to perform its obligations under
         the term hereof and (i) Guarantor is organized and validly existing
         under the laws of the State of Maryland, (ii) Guarantor has complied
         with all provisions of applicable law in connection with all aspects of
         this Guaranty, and (iii) the person executing this Guaranty has all the
         requisite power and authority to execute and deliver this Guaranty;

                  (6)      to the best of Guarantor's knowledge, there is no
         action, suit, proceeding, or investigation pending or threatened
         against or affecting Guarantor at law, in equity, in admiralty or
         before any arbitrator or any governmental department, commission,
         board,

                                        5
<PAGE>

         bureau, agency or instrumentality (domestic or foreign) which is likely
         to materially and adversely impair the ability of Guarantor to perform
         its obligations under this Guaranty;

                  (7)      the execution and delivery of and the performance by
         Guarantor of its obligations under this Guaranty have been duly
         authorized by all necessary action on the part of Guarantor and do not
         (i) violate any provision of any law, rule, regulation (including,
         without limitation, Regulation U or X of the Board of Governors of the
         Federal Reserve System of the United States), order, writ, judgment,
         decree, determination or award presently in effect having applicability
         to Guarantor or the organizational documents of Guarantor the
         consequences of which violation is likely to materially and adversely
         impair the ability of Guarantor to perform its obligations under this
         Guaranty or (ii) violate or conflict with, result in a breach of or
         constitute (with due notice or lapse of time or both) a default under
         any indenture, agreement or other instrument to which Guarantor is a
         party, or by which Guarantor or any of its property is bound, the
         consequences of which violation, conflict, breach or default is likely
         to materially and adversely impair the ability of Guarantor to perform
         its obligations under this Guaranty;

                  (8)      this Guaranty has been duly executed by Guarantor and
         constitutes the legal, valid and binding obligation of Guarantor,
         enforceable against it 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;

                  (9)      no authorization, consent, approval, license or
         formal exemption from, nor any filing, declaration or registration
         with, any Federal, state, local or foreign court, governmental agency
         or regulatory authority is required in connection with the making and
         performance by Guarantor of this Guaranty, except those which have
         already been obtained; and

                  (10)     Guarantor is not an "investment company" as that term
         is defined in, nor is it otherwise subject to regulation under, the
         Investment Company Act of 1940, as amended.

                  9.       Guarantor and Administrative Agent each acknowledge
and agree that this Guaranty is a guarantee of payment and performance and not
of collection and enforcement in respect of any obligations which may accrue to
the Administrative Agent and/or the Banks from Borrower under the provisions of
any Loan Document.

                  10.      Subject to the terms and conditions of the Credit
Agreement, and in conjunction therewith, the Administrative Agent or any Bank
may assign any or all of its rights under this Guaranty. In the event of any
such assignment, the Administrative Agent shall give Guarantor prompt notice of
same. If the Administrative Agent or any Bank elects to sell all the Loans or
participations in the Loans and the Loan Documents, including this Guaranty, the

                                        6
<PAGE>

Administrative Agent or any Bank may forward to each purchaser and prospective
purchaser all documents and information relating to this Guaranty or to
Guarantor, whether furnished by Borrower or Guarantor or otherwise, subject to
the terms and conditions of the Credit Agreement.

                  11.      Guarantor agrees, upon the written request of the
Administrative Agent, to execute and deliver to the Administrative Agent, from
time to time, any modification or amendment hereto or any additional instruments
or documents reasonably considered necessary by the Administrative Agent or its
counsel to cause this Guaranty to be, become or remain valid and effective in
accordance with its terms, provided, that, any such modification, amendment,
additional instrument or document shall not increase Guarantor's obligations or
diminish its rights hereunder and shall be reasonably satisfactory as to form to
Guarantor and to Guarantor's counsel.

                  12.      The representations and warranties of Guarantor set
forth in this Guaranty shall survive until this Guaranty shall terminate in
accordance with the terms hereof.

                  13.      This Guaranty contains the entire agreement among the
parties with respect to the subject matter hereof and supersede all prior
agreements relating to such subject matter and may not be modified, amended,
supplemented or discharged except by a written agreement signed by Guarantor and
the Administrative Agent.

                  14.      If all or any portion of any provision contained in
this Guaranty shall be determined to be invalid, illegal or unenforceable in any
respect for any reason, such provision or portion thereof shall be deemed
stricken and severed from this Guaranty and the remaining provisions and
portions thereof shall continue in full force and effect.

                  15.      This Guaranty may be executed in counterparts which
together shall constitute the same instrument.

                  16.      All notices, requests and other communications to any
party hereunder shall be in writing (including bank wire, telex, facsimile
transmission followed by telephonic confirmation or similar writing) and shall
be addressed to such party at the address set forth below or to such other
address as may be identified by any party in a written notice to the others:

                  17.      Any acknowledgment or new promise, whether by payment
of principal or interest or otherwise by Borrower or Guarantor, with respect to
the Guaranteed Obligations shall, if the statute of limitations in favor of
Guarantor against the Administrative Agent shall have commenced to run, toll the
running of such statute of limitations, and if the period of such statute of
limitations shall have expired, prevent the operation of such statute of
limitations.

                  18.      This Guaranty shall be binding upon Guarantor and its
successors and assigns and shall inure to the benefit of the Administrative
Agent, the Syndication Agent, the Co-Documentation Agents, and the Banks and
their successors and permitted assigns.

                  19.      The failure of the Administrative Agent to enforce
any right or remedy hereunder, or promptly to enforce any such right or remedy,
shall not constitute a waiver thereof, nor give rise to any estoppel against the
Administrative Agent, nor excuse Guarantor from its obligations hereunder. Any
waiver of any such right or remedy to be enforceable against the Administrative
Agent must be expressly set forth in a writing signed by the Administrative
Agent.

                  20.      (a)      THIS GUARANTY AND THE RIGHTS AND OBLIGATIONS
OF THE PARTIES HEREUNDER SHALL BE CONSTRUED IN ACCORDANCE WITH AND

<PAGE>

BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

                           (b)      Any legal action or proceeding with respect
to this Guaranty and any action for enforcement of any judgment in respect
thereof may be brought in the courts of the State of New York or of the United
States of America for the Southern District of New York, and, by execution and
delivery of this Guaranty, the Guarantor 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
Guarantor irrevocably consents to the service of process out of any of the
aforementioned courts in any such action or proceeding by the mailing of copies
thereof by registered or certified mail, postage prepaid, to the Guarantor at
its address for notices set forth herein. The Guarantor 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 Guaranty 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 Guarantor in any other
jurisdiction.

                           (c)      GUARANTOR HEREBY WAIVES ITS RIGHTS TO A JURY
TRIAL OF ANY AND ALL CLAIMS OR CAUSES OF ACTION BASED UPON OR ARISING OUT OF
THIS GUARANTY. IT IS HEREBY ACKNOWLEDGED BY GUARANTOR THAT THE WAIVER OF A JURY
TRIAL IS A MATERIAL INDUCEMENT FOR THE ADMINISTRATIVE AGENT TO ACCEPT THIS
GUARANTY AND THAT THE LOANS MADE BY THE BANKS ARE MADE IN RELIANCE UPON SUCH
WAIVER. GUARANTOR FURTHER WARRANTS AND REPRESENTS THAT SUCH WAIVER HAS BEEN
KNOWINGLY AND VOLUNTARILY MADE, FOLLOWING CONSULTATION WITH LEGAL COUNSEL. IN
THE EVENT OF LITIGATION, THIS GUARANTY MAY BE FILED BY THE ADMINISTRATIVE AGENT
IN COURT AS A WRITTEN CONSENT TO A NON-JURY TRIAL.

                           (d)      Guarantor does hereby further covenant and
agree to and with the Administrative Agent that Guarantor may be joined in any
action against Borrower in connection with the Loan Documents and that recovery
may be had against Guarantor in such action or in any independent action against
Guarantor (with respect to the Guaranteed Obligations), without the
Administrative Agent first pursuing or exhausting any remedy or claim against
Borrower or its successors or assigns. Guarantor also agrees that, in an action
brought with respect to the Guaranteed Obligations in any jurisdiction, it shall
be conclusively bound by the judgment in any such action by the Administrative
Agent (wherever brought) against Borrower or its successors or assigns, as if
Guarantor were a party to such action, even though Guarantor was not joined as a
party in such action.

                           (e)      Guarantor agrees to pay all reasonable
expenses (including, without limitation, attorneys' fees and disbursements)
which may be incurred by the

                                        9

Administrative Agent or the Banks in connection with the enforcement of their
rights under this Guaranty, whether or not suit is initiated.

                  21.      Notwithstanding anything to the contrary contained
herein, this Guaranty shall terminate and be of no further force or effect upon
the full performance and payment of the Guaranteed Obligations hereunder and the
termination of the Commitments under the Credit Agreement. Upon termination of
this Guaranty in accordance with the terms of this Guaranty, the Administrative
Agent promptly shall deliver to Guarantor such documents as Guarantor or
Guarantor's counsel reasonably may request in order to evidence such
termination.

                  22.      All of the Administrative Agent's rights and remedies
under each of the Loan Documents or under this Guaranty are intended to be
distinct, separate and cumulative and no such right or remedy therein or herein
mentioned is intended to be in exclusion of or a waiver of any other right or
remedy available to the Administrative Agent.

                  23.      The Guarantor shall not use any assets of an
"employee benefit plan" within the meaning of Section 3(3) of ERISA or a "plan"
within the meaning of Section 4975(e)(1) of the Internal Revenue Code (the
"Code") to repay or secure the Loan, the Note, the Obligations or this Guaranty.
The Guarantor shall not assign, sell, pledge, encumber, transfer, hypothecate or
otherwise dispose of any of its rights or interests (direct or indirect) in
Borrower, or attempt to do any of the foregoing or suffer any of the foregoing,
or permit any party with a direct or indirect interest or right in Borrower to
do any of the foregoing, if such action would cause the Note, the Loan, the
Obligations, this Guaranty, or any of the Loan Documents or the exercise of any
of the Administrative Agent's, the Syndication Agent's, any Co-Documentation
Agent's, any Arranger's or Bank's rights in connection therewith, to constitute
a prohibited transaction under ERISA or the Code (unless the Guarantor furnishes
to the Administrative Agent a legal opinion satisfactory to the Administrative
Agent that the transaction is exempt from the prohibited transaction provisions
of ERISA and the Code (and for this purpose, the Administrative Agent, the
Syndication Agent, the Co-Documentation Agents, the Arrangers and the Banks, by
accepting the benefits of this Guaranty, hereby agree to supply Guarantor all
relevant non-confidential, factual information reasonably necessary to such
legal opinion and reasonably requested by Guarantor) or would otherwise result
in the Administrative Agent, the Syndication Agent, the Co-Documentation Agents,
or any of the Arrangers or Banks being deemed in violation of Sections 404 or
406 of ERISA or Section 4975 of the Code or would otherwise result in the
Administrative Agent, the Syndication Agent, the Co-Documentation Agents, or any
of the Arrangers or Banks being a fiduciary or party in interest under ERISA or
a "disqualified person" as defined in Section 4975(e)(2) of the Code with
respect to an "employee benefit plan" within the meaning of Section 3(3) of
ERISA or a "plan" within the meaning of Section 4975(e)(1) of the Code. The
Guarantor shall indemnify and hold each of the Administrative Agent, the
Syndication Agent, the Co-Documentation Agents, the Arrangers and the Banks free
and harmless from and against all loss, costs (including attorneys' fees and
expenses), expenses, taxes and damages (including consequential damages) that
each of the Administrative Agent, the Syndication Agent, the Co-Documentation
Agents, the Arrangers and the Banks may suffer by reason of the investigation,
defense and settlement of claims and in

                                       10

obtaining any prohibited transaction exemption under ERISA necessary in
Administrative Agent's reasonable judgment as a result of Guarantor's action or
inaction or by reason of a breach of the foregoing provisions by Guarantor.

                  24.      This Guaranty shall become effective simultaneously
with the making of the initial Loans under the Credit Agreement.
