                                    THE LOANS

           Section 2.01   Ratable Loans; Bid Rate Loans; Purpose. (a) Subject to
the terms and conditions of this Agreement, the Banks agree to make loans to
Borrower as provided in this Article II.

           (b) Each of the Banks severally agrees to make a loan to Borrower
(each such loan by a Bank, a "Ratable Loan") in an amount up to its Loan
Commitment pursuant to which the Bank shall from time to time advance and
re-advance to Borrower an amount equal to its Pro Rata Share of the excess (the
"Available Total Loan Commitment") of the Total Loan Commitment over the sum of
(1) all previous advances (including Bid Rate Loans and Swing Loans) made by the
Banks which remain unpaid and (2) the outstanding amount of all Letters of
Credit. Within the limits set forth herein, Borrower may borrow from time to
time under this paragraph (b) and prepay from time to time pursuant to Section
2.09 (subject, however, to the restrictions on prepayment set forth in said
Section), and thereafter re-borrow pursuant to this paragraph (b). The Ratable
Loans may be outstanding as (1) Base Rate Loans; (2) LIBOR Loans; or (3) a
combination of the foregoing, as Borrower shall elect and notify Administrative
Agent in accordance with Section 2.14. The LIBOR Loan, Bid Rate Loan and Base
Rate Loan of each Bank shall be maintained at such Bank's Applicable Lending
Office.

           (c) In addition to Ratable Loans pursuant to paragraph (b) above, so
long as Borrower's Credit Rating is BBB- or better by S&P or Baa(3) or better by
Moody's, one or more Banks may, at Borrower's request and in their sole
discretion, make non-ratable loans which shall bear interest at the LIBOR Bid
Rate in accordance with Section 2.02 (such loans being referred to in this
Agreement as "Bid Rate Loans"). Borrower may borrow Bid Rate Loans from time to
time pursuant to this paragraph (c) in an amount up to the Available Total Loan
Commitment at the time of the borrowing (taking into account any repayments of
the Loans made simultaneously therewith) and shall repay such Bid Rate Loans as
required by Section 2.08, and it may thereafter re-borrow pursuant to this
paragraph (c); provided, however, that the aggregate outstanding principal
amount of Bid Rate Loans at any particular time shall not exceed the Bid
Borrowing Limit.

           (d) The obligations of the Banks under this Agreement are several,
and no Bank shall be responsible for the failure of any other Bank to make any
advance of a Loan to be made by such other Bank. However, the failure of any
Bank to make any advance of the Loan to be made by it hereunder on the date
specified therefor shall not relieve any other Bank of its obligation to make
any advance of its Loan specified hereby to be made on such date.

           (e) Borrower shall use the proceeds of the Loans for general capital
and working capital requirements of Borrower and its Consolidated Businesses and
UJVs (which shall include, but not be limited to, Acquisitions and/or costs
incurred in connection with the development, construction or reconstruction of
multi-family real estate properties). In no event shall proceeds of the Loans be
used in a manner that would violate Regulation U or in connection with a hostile
acquisition.

(x) one (1) hour prior to the deadline for the other Banks in the case of a
LIBOR Auction or (y) thirty (30) minutes prior to the deadline for the other

this Agreement to its entitlement to an advance) be irrevocable except with the
written consent of Administrative Agent given on the

              (vi)   the identity of the quoting Bank.

A Bid Rate Quote may set forth up to three (3) separate offers by the quoting
Bank with respect to each Interest Period specified in the related Invitation
for Bid Rate Quotes.

           (3)    Any Bid Rate Quote shall be disregarded if it:

              (i)    is not substantially in conformity with EXHIBIT G-3 or does
     not specify all of the information required by sub-paragraph (c)(2) above;

              (ii)   contains qualifying, conditional or similar language
     (except for an aggregate limitation as provided in sub-paragraph (c)(2)(ii)
     above);

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

<PAGE>   26


              (iv)   arrives after the time set forth in sub-paragraph (c)(1)
     above.


           (d) Administrative Agent shall (x) not later than 3:00 p.m. (New York
time) on the fourth Banking Day prior to the proposed date of funding of the
LIBOR Bid Rate Loan(s) in the case of a LIBOR Auction or (y) not later than
10:30 a.m. (New York time) on the Banking Day immediately preceding the proposed
date of funding of the Absolute Bid Rate Loan(s) in the case of an Absolute Rate
Auction, notify Borrower in writing of the terms of any Bid Rate Quote submitted
by a Bank that is in accordance with paragraph (c). In addition, Administrative
Agent shall, on the Banking Day of its receipt thereof, notify Borrower in
writing of any Bid Rate Quote that amends, modifies or is otherwise inconsistent
with a previous Bid Rate Quote submitted by such Bank with respect to the same
Bid Rate Quote Request. Any such subsequent Bid Rate Quote shall be disregarded
by Administrative Agent unless such subsequent Bid Rate Quote is submitted
solely to correct a manifest error in such former Bid Rate Quote. Administrative
Agent's notice to Borrower shall specify (A) the aggregate principal amount of
Bid Rate Loans for which offers have been received for each Interest Period
specified in the related Bid Rate Quote Request, (B) the respective principal
amounts, LIBOR Bid Margins and Absolute Bid Rates so offered and (C) if
applicable, limitations on the aggregate principal amount of Bid Rate Loans for
which offers in any single Bid Rate Quote may be accepted.

           (e) Not later than (x) 9:30 a.m. (New York time) on the third Banking
Day prior to the proposed date of funding of the LIBOR Bid Rate Loan in the case
of a LIBOR Auction or (y) the Banking Day immediately preceding the proposed
date of funding of the Absolute Bid Rate Loan in the case of an Absolute Rate
Auction, Borrower shall notify Administrative Agent of its acceptance or
non-acceptance of the offers so notified to it pursuant to paragraph (d). A
notice of acceptance shall be substantially in the form of EXHIBIT G-4 and shall
specify the aggregate principal amount of offers for each Interest Period that
are accepted. Borrower may accept any Bid Rate Quote in whole or in part;
provided that:

              (i)    the principal amount of each Bid Rate Loan may not exceed
     the applicable amount set forth in the related Bid Rate Quote Request or be
     less than $500,000 per Bank and shall be an integral multiple of $100,000;

              (ii)   acceptance of offers with respect to a particular Interest
     Period may only be made on the basis of ascending LIBOR Bid Margins or
     Absolute Bid Rates, as the case may be, offered for such Interest Period
     from the lowest effective cost; and

              (iii)  Borrower may not accept any offer that is described in
     sub-paragraph (c)(3) or that otherwise fails to comply with the
     requirements of this Agreement.

           (f) If offers are made by two (2) or more Banks with the same LIBOR
Bid Margins or Absolute Bid 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 Bid Rate Loans in
respect of which such offers are accepted shall be allocated by Administrative
Agent among such Banks as nearly as possible (in multiples of $100,000, as
Administrative Agent may deem appropriate) in proportion to the aggregate
principal amounts of such offers. Administrative Agent shall promptly (and in
any event within one (1) Banking Day after such offers are accepted) notify
Borrower and each such Bank in


                                       21
<PAGE>   27


writing of any such allocation of Bid Rate Loans. Determinations by
Administrative Agent of the allocation of Bid Rate Loans shall be conclusive in
the absence of manifest error.

           (g) In the event that Borrower accepts the offer(s) contained in one
(1) or more Bid Rate Quotes in accordance with paragraph (e), the Bank(s) making
such offer(s) shall make a Bid Rate Loan in the accepted amount (as allocated,
if necessary, pursuant to paragraph (f)) on the date specified therefor, in
accordance with the procedures specified in Section 2.04, and such Bid Rate Loan
shall bear interest at the accepted LIBOR Bid Rate or Absolute Bid Rate, as the
case may be, for the applicable Interest Period.

           (h) Notwithstanding anything to the contrary contained herein, each
Bank shall be required to fund its Pro Rata Share of the Available Total Loan
Commitment in accordance with Section 2.01(b) despite the fact that any Bank's
Loan Commitment may have been or may be exceeded as a result of such Bank's
making Bid Rate Loans.

           (i) A Bank who is notified that it has been selected to make a Bid
Rate Loan as provided above may designate its Designated Lender (if any) to fund
such Bid Rate Loan on its behalf, as described in Section 12.16. Any Designated
Lender which funds a Bid Rate Loan shall on and after the time of such funding
become the obligee under such Bid Rate Loan and be entitled to receive payment
thereof when due. No Bank shall be relieved of its obligation to fund a Bid Rate
Loan, and no Designated Lender shall assume such obligation, prior to the time
the applicable Bid Rate Loan is funded.

           (j) Administrative Agent shall promptly notify each Bank which
submitted a Bid Rate Quote of Borrower's acceptance or non-acceptance thereof.
At the request of any Bank which submitted a Bid Rate Quote, Administrative
Agent will promptly notify all Banks which submitted Bid Rate Quotes of (a) the
aggregate principal amount of, and (b) the range of Absolute Bid Rates or LIBOR
Bid Margins of, the accepted Bid Rate Loans for each requested Interest Period.

           Section 2.03   Advances, Generally. The Initial Advance shall be in
the minimum amount of $500,000 and in integral multiples of $100,000 above such
amount and shall be made upon satisfaction of the conditions set forth in
Section 4.01. Subsequent advances shall be made no more frequently than weekly
thereafter, upon satisfaction of the conditions set forth in Section 4.02. The
amount of each advance subsequent to the Initial Advance shall be in the minimum
amount of $500,000 (unless less than $500,000 is available for disbursement
pursuant to the terms hereof at the time of any subsequent advance, in which
case the amount of such subsequent advance shall be equal to such remaining
availability) and in integral multiples of $100,000 above such amount.
Additional restrictions on the amounts and timing of, and conditions to the
making of, advances of Bid Rate Loans are set forth in Section 2.02.

           Section 2.04   Procedures for Advances. In the case of advances of
Ratable Loans hereunder, Borrower shall submit to Administrative Agent a request
for each advance, stating the amount requested and certifying the purpose, in
general terms, for which such advance is to be used, no later than 11:00 a.m.
(New York time) on the date, in the case of advances of Base Rate Loans, which
is one (1) Banking Day, and, in the case of advances of LIBOR Loans, which is
three (3) Banking Days, prior to the date the advance is to be made. In


                                       22
<PAGE>   28


the case of advances of Swing Loans hereunder, Borrower shall submit to
Administrative Agent a request for such advance, stating the amount requested
and certifying the purpose, in general terms, for which such advance is to be
used, no later than 11:00 a.m. (New York time) on the date which is one (1)
Banking Day prior to the date the advance is to be made. In the case of advances
of Bid Rate Loans hereunder, Borrower shall submit a Bid Rate Quote Request at
the time specified in Section 2.02, accompanied by a certification of the
purpose, in general terms, for which the advance is to be used. Administrative
Agent, on the Banking Day of its receipt and approval of the request for
advance, will so notify the Banks (or, in the case of Swing Loans, the Swing
Lender) either by telephone or by facsimile. Not later than 11:00 a.m. (New York
time) on the date of each advance, each Bank (in the case of Ratable Loans) or
the applicable Bank(s) (in the case of Bid Rate Loans) or the Swing Lender (in
the case of Swing Loans) shall, through its Applicable Lending Office and
subject to the conditions of this Agreement, make the amount to be advanced by
it on such day available to Administrative Agent, at Administrative Agent's
Office and in immediately available funds for the account of Borrower. The
amount so received by Administrative Agent shall, subject to the conditions of
this Agreement, be made available to Borrower, in immediately available funds,
by Administrative Agent's crediting an account of Borrower designated by
Borrower and maintained with Administrative Agent at Administrative Agent's
Office.

           Section 2.05   Interest Periods; Renewals. In the case of the LIBOR
Loans and Bid Rate Loans, Borrower shall select an Interest Period of any
duration in accordance with the definition of Interest Period in Section 1.01,
subject to the following limitations: (1) no Interest Period may extend beyond
the Maturity Date; and (2) if an Interest Period would end on a day which is not
a Banking Day, such Interest Period shall be extended to the next Banking Day,
unless such Banking Day would fall in the next calendar month, in which event
such Interest Period shall end on the immediately preceding Banking Day. Only
twelve (12) discrete segments of a Bank's Ratable Loan bearing interest at a
LIBOR Interest Rate, for a designated Interest Period, pursuant to a particular
Election, Conversion or Continuation, may be outstanding at any one time (each
such segment of each Bank's Ratable Loan corresponding to a proportionate
segment of each of the other Banks' Ratable Loans).

           Upon notice to Administrative Agent as provided in Section 2.14,
Borrower may Continue any LIBOR Loan on the last day of the Interest Period of
the same or different duration in accordance with the limitations provided
above. If Borrower shall fail to give notice to Administrative Agent of such a
Continuation, such LIBOR Loan shall automatically become a LIBOR Loan with an
Interest Period of one (1) month on the last day of the current Interest Period.
Administrative Agent shall notify each of the Banks, either by telephone or by
facsimile, at least two (2) Banking Days prior to the termination of the
Interest Period in question in the event of such failure by Borrower to give
such notice of Continuation.

           Section 2.06   Interest. Borrower shall pay interest to
Administrative Agent for the account of the applicable Bank on the outstanding
and unpaid principal amount of the Loans, at a rate per annum as follows: (1)
for Base Rate Loans at a rate equal to the Base Rate plus the Applicable Margin;
(2) for LIBOR Loans at a rate equal to the applicable LIBOR Interest Rate plus
the Applicable Margin; (3) for LIBOR Bid Rate Loans at a rate equal to the
applicable LIBOR Bid Rate; (4) for Absolute Bid Rate Loans at a rate equal to
the applicable Absolute Bid Rate; and (5) for Swing Loans at a three (3)-day
LIBOR rate, as determined by the Swing


                                       23
<PAGE>   29


Lender. Any principal amount not paid when due (when scheduled, at acceleration
or otherwise) shall bear interest thereafter, payable on demand, at the Default
Rate.

           The interest rate on Base Rate Loans shall change when the Base Rate
changes. Interest on Base Rate Loans, LIBOR Loans, Bid Rate Loans and Swing
Loans shall not exceed the maximum amount permitted under applicable law.
Interest shall be calculated for the actual number of days elapsed on the basis
of, in the case of Base Rate Loans, LIBOR Loans, Bid Rate Loans and Swing Loans,
three hundred sixty (360) days.

           Accrued interest shall be due and payable in arrears upon and with
respect to any payment or prepayment of principal and, (x) in the case of Base
Rate Loans, LIBOR Loans and Swing Loans, on the first Banking Day of each
calendar month and (y) in the case of Bid Rate Loans, at the expiration of the
Interest Period applicable thereto; provided, however, that interest accruing at
the Default Rate shall be due and payable on demand.

           Section 2.07   Fees. (a) Borrower agrees to pay to and for the
accounts of the parties specified therein, the fees provided for in the
Supplemental Fee Letter.

           (b) Borrower shall pay to Administrative Agent for the account of
each Bank a facility fee computed on the daily Loan Commitment of such Bank
(irrespective of usage) at a rate per annum equal to the daily Facility Fee
Rate, calculated on the basis of a year of three hundred sixty (360) days for
the actual number of days elapsed. The accrued facility fee shall be due and
payable quarterly in arrears on the tenth (10th) day of October, January, April
and July of each year, commencing on the first such date after the Closing Date,
and upon the Maturity Date (as stated or by acceleration or otherwise) or
earlier termination of the Loan Commitments.

           Section 2.08   Notes. The Ratable Loan made by each Bank under this
Agreement shall be evidenced by, and repaid with interest in accordance with, a
single promissory note of Borrower in the form of EXHIBIT B duly completed and
executed by Borrower, in the principal amount equal to such Bank's Loan
Commitment, payable to such Bank for the account of its Applicable Lending
Office (each such note, as the same may hereafter be amended, modified,
extended, severed, assigned, renewed or restated from time to time, including
any substitute notes pursuant to Section 3.07 or 12.05, a "Ratable Loan Note").
The Bid Rate Loans of the Banks shall be evidenced by a single global promissory
note of Borrower, in the form of EXHIBIT B-1, duly completed and executed by
Borrower, in the principal amount of $400,000,000, payable to Administrative
Agent for the account of the respective Banks making Bid Rate Loans (such note,
as the same may hereafter be amended, modified, extended, severed, assigned,
substituted, renewed or restated from time to time, the "Bid Rate Loan Note").
The Swing Loan of the Swing Lender shall be evidenced by, and repaid with
interest in accordance with, a promissory note of Borrower, in the form of
EXHIBIT B-2, duly completed and executed by Borrower, payable to the Swing
Lender (such note, as the same may hereafter be amended, modified extended,
severed, assigned, substituted, renewed or restated from time to time, the
"Swing Loan Note"). A particular Bank's Ratable Loan Note, together with its
interest, if any, in the Bid Rate Loan Note, and, in the case of the Swing
Lender, the Swing Loan Note, are referred to collectively in this Agreement as
such Bank's "Note"; all such Ratable Loan Notes and interests and Swing Loan
Notes are referred to collectively in this Agreement as the "Notes". The Ratable
Loan Notes shall mature, and all outstanding principal


                                       24
<PAGE>   30


and accrued interest and other sums thereunder shall be paid in full, on the
Maturity Date, as the same may be accelerated. The outstanding principal amount
of each Bid Rate Loan evidenced by the Bid Rate Loan Note, and all accrued
interest and other sums with respect thereto, shall become due and payable to
the Bank making such Bid Rate Loan at the earlier of the expiration of the
Interest Period applicable thereto or the Maturity Date, as the same may be
accelerated. Principal amounts evidenced by the Swing Loan Notes shall become
due and payable three (3) Banking Days after said amounts are advanced.

           Each Bank is hereby authorized by Borrower to endorse on the schedule
attached to the Ratable Loan Note held by it, the amount of each advance and
each payment of principal received by such Bank for the account of its
Applicable Lending Office(s) on account of its Ratable Loan, which endorsement
shall, in the absence of manifest error, be conclusive as to the outstanding
balance of the Ratable Loan made by such Bank. The Swing Lender is hereby
authorized by Borrower to endorse on the schedule attached to the Swing Loan
Note held by it, the amount of each advance and each payment of principal
received by the Swing Lender for the account of its Applicable Lending Office(s)
on account of its Swing Loan, which endorsement shall, in the absence of
manifest error, be conclusive as to the outstanding balance of the Swing Loan
made by the Swing Lender. Administrative Agent is hereby authorized by Borrower
to endorse on the schedule attached to the Bid Rate Loan Note the amount of each
LIBOR Bid Rate Loan and/or Absolute Bid Rate Loan, the name of the Bank making
the same, the date of the advance thereof, the interest rate applicable thereto
and the expiration of the Interest Period applicable thereto (i.e., the maturity
date thereof). The failure by Administrative Agent or any Bank to make such
notations with respect to the Loans or each advance or payment shall not limit
or otherwise affect the obligations of Borrower under this Agreement or the
Notes.

           In case of any loss, theft, destruction or mutilation of any Bank's
Note, Borrower shall, upon its receipt of an affidavit of an officer of such
Bank as to such loss, theft, destruction or mutilation and an appropriate
indemnification, execute and deliver a replacement Note to such Bank in the same
principal amount and otherwise of like tenor as the lost, stolen, destroyed or
mutilated Note.

           Section 2.09   Prepayments. Without prepayment premium or penalty but
subject to Section 3.05, Borrower may, upon at least one (1) Banking Day's
notice to Administrative Agent in the case of the Base Rate Loans and Swing
Loans, and at least three (3) Banking Days' notice to Administrative Agent in
the case of LIBOR Loans, prepay the Ratable Loans, provided that (1) any partial
prepayment under this Section shall be in integral multiples of $500,000; (2) a
LIBOR Loan or Swing Loan may be prepaid at any time, subject, however, to the
provisions of Section 3.05; and (3) each prepayment under this Section shall
include all interest accrued on the amount of principal prepaid through the date
of prepayment. Prepayment of Bid Rate Loans shall not be permitted.

           Section 2.10   Cancellation of Commitments. (a) At any time, Borrower
shall have the right, without premium or penalty, to terminate any unused Loan
Commitments or unused commitment of the Swing Lender to make Swing Loans, in
whole or in part, from time to time, provided that: (1) Borrower shall give
notice of each such termination to Administrative Agent and the Swing Lender, if
applicable, no later then 10:00 a.m. (New York time) on the date which is
fifteen (15) Banking Days prior to the effectiveness of such termination; (2)
the Loan Commitments of each of the Banks, or Swing Lender, as applicable, must
be terminated ratably and simultaneously with those of the other Banks, or Swing
Lender, as applicable; and (3) each partial termination of the Loan Commitments,
or commitments to make Swing Loans, as a whole (and corresponding reduction of
the Total Loan Commitment) shall be in an integral multiple of $1,000,000.


                                       25
<PAGE>   31


           (b) The Loan Commitments, to the extent terminated, may not be
reinstated.

           Section 2.11   Method of Payment. Borrower shall make each payment
under this Agreement and under the Notes not later than 11:00 a.m. (New York
time) on the date when due in Dollars to Administrative Agent at Administrative
Agent's Office in immediately available funds. Administrative Agent will
thereafter, on the day of its receipt of each such payment, cause to be
distributed to each Bank (1) such Bank's appropriate share (based upon the
respective outstanding principal amounts and rate(s) of interest under the Notes
of the Banks) of the payments of principal and interest in like funds for the
account of such Bank's Applicable Lending Office; and (2) fees payable to such
Bank in accordance with the terms of this Agreement. In the event Administrative
Agent fails to pay funds received from Borrower to the Banks on the date on
which Borrower is credited with payment, Administrative Agent shall pay interest
on such amounts at the Federal Funds Rate until such payment to the Banks is
made. Borrower hereby authorizes Administrative Agent and the Banks, if and to
the extent payment by Borrower is not made when due under this Agreement or
under the Notes, to charge from time to time against any account Borrower
maintains with Administrative Agent or any Bank any amount so due to
Administrative Agent and/or the Banks.

           Except to the extent provided in this Agreement, whenever any payment
to be made under this Agreement or under the Notes is due on any day other than
a Banking Day, such payment shall be made on the next succeeding Banking Day,
and such extension of time shall in such case be included in the computation of
the payment of interest and other fees, as the case may be.

           Section 2.12   Elections, Conversions or Continuation of Loans.
Subject to the provisions of Article III and Sections 2.05 and 2.13, Borrower
shall have the right to Elect to have all or a portion of any advance of the
Ratable Loans be LIBOR Loans, to Convert Base Rate Loans into LIBOR Loans, to
Convert LIBOR Loans into Base Rate Loans, or to Continue LIBOR Loans as LIBOR
Loans, at any time or from time to time, provided that (1) Borrower shall give
Administrative Agent notice of each such Election, Conversion or Continuation as
provided in Section 2.14; and (2) a LIBOR Loan may be Converted or Continued
only on the last day of the applicable Interest Period for such LIBOR Loan.
Except as otherwise provided in this Agreement, each Election, Continuation and
Conversion shall be applicable to each Bank's Ratable Loan in accordance with
its Pro Rata Share.

           Section 2.13   Minimum Amounts. With respect to the Ratable Loans as
a whole, each Election and each Conversion shall be in an amount at least equal
to $1,000,000 and in integral multiples of $500,000.

           Section 2.14   Certain Notices Regarding Elections, Conversions and
Continuations of Loans. Notices by Borrower to Administrative Agent of
Elections, Conversions and Continuations of LIBOR Loans shall be irrevocable and
shall be effective only if received by Administrative Agent not later than 10:30
a.m. (New York time) on the number of Banking Days prior to the date of the
relevant Election, Conversion or Continuation specified below:

</TABLE>

Promptly following its receipt of any such notice, and no later than the close
of business on the Banking Day of such receipt, Administrative Agent shall so
advise the Banks either by telephone or by facsimile. Each such notice of
Election shall specify the portion of the amount of the advance that is to be
LIBOR Loans (subject to Section 2.13) and the duration of the Interest Period
applicable thereto (subject to Section 2.05); each such notice of Conversion
shall specify the LIBOR Loans or Base Rate Loans to be Converted; and each such
notice of Conversion or Continuation shall specify the date of Conversion or
Continuation (which shall be a Banking Day), the amount thereof (subject to
Section 2.13) and the duration of the Interest Period applicable thereto
(subject to Section 2.05). In the event that Borrower fails to Elect to have any
portion of an advance of the Ratable Loans be LIBOR Loans, the entire amount of
such advance shall constitute Base Rate Loans. In the event that Borrower fails
to Continue LIBOR Loans within the time period and as otherwise provided in this
Section, such LIBOR Loans will automatically become LIBOR Loans with an Interest
Period of one (1) month on the last day of the then current applicable Interest
Period for such LIBOR Loans. Administrative Agent shall notify each of the
Banks, either by telephone or by facsimile, at least two (2) Banking Days prior
to the termination of the Interest Period in question in the event of such
failure by Borrower.

           Section 2.15   Late Payment Premium. Borrower shall, at
Administrative Agent's option and upon notice to Borrower, pay to Administrative
Agent for the account of the Banks a late payment premium in the amount of 4% of
any payments of interest under the Loans made more than ten (10) days after the
due date thereof, which shall be due with any such late payment.

           Section 2.16   Letters of Credit. (a) Borrower, by notice to
Administrative Agent, may request, in lieu of advances of proceeds of the
Ratable Loans, that Administrative Agent issue unconditional, irrevocable
standby letters of credit (each, a "Letter of Credit") for the account of
Borrower, payable by sight drafts, for such beneficiaries and with such other
terms as Borrower shall specify. Promptly upon issuance of a Letter of Credit,
Administrative Agent shall notify each of the Banks.

           (b) The amount of any Letter of Credit shall be limited to the lesser
of (x) $75,000,000 less the aggregate amount of all Letters of Credit
theretofore issued or (y) the Available Total Loan Commitment, it being
understood that the amount of each Letter of Credit issued and outstanding shall
effect a reduction, by an equal amount, of the Available Total Loan Commitment
(such reduction to be allocated to each Bank's Ratable Loan ratably in
accordance with the Banks' respective Pro Rata Shares).


                                       27
<PAGE>   33


           (c) The amount of each Letter of Credit shall be further subject to
the limitations applicable to amounts of advances set forth in Section 2.03 and
the procedures for the issuance of each Letter of Credit shall be the same as
the procedures applicable to the making of advances as set forth in the first
sentence of Section 2.04. Administrative Agent's issuance of each Letter of
Credit shall be subject to Administrative Agent's determination that Borrower
has satisfied all conditions precedent to its entitlement to an advance of
proceeds of the Loans.

           (d) Each Letter of Credit shall expire no later than one (1) month
prior to the Maturity Date, but may have a so-called "evergreen" clause allowing
for the extension of the expiration date thereof upon the extension of the
Maturity Date pursuant to Section 2.19.

           (e) In connection with, and as a further condition to the issuance
of, each Letter of Credit, Borrower shall execute and deliver to Administrative
Agent an application for the Letter of Credit on Administrative Agent's standard
form therefor, together with such other documents, opinions and assurances as
Administrative Agent shall reasonably require.

           (f) In connection with each Letter of Credit, Borrower hereby
covenants to pay to Administrative Agent the following fees: (1) a fee, payable
quarterly in arrears (on the first Banking Day of each calendar quarter
following the issuance of the Letter of Credit), for the account of the Banks,
computed daily on the amount of the Letter of Credit issued and outstanding at a
rate per annum equal to the "Banks' L/C Fee Rate" (as hereinafter defined) and
(2) the fee, for Administrative Agent's own account, required by the
Supplemental Fee Letter between Borrower and Fleet. For purposes of this
Agreement, the "Banks' L/C Fee Rate" shall mean, at any time, a rate per annum
equal to the Applicable Margin for LIBOR Loans less 0.125% per annum. It is
understood and agreed that the last installment of the fees provided for in this
paragraph (f) with respect to any particular Letter of Credit shall be due and
payable on the first day of the calendar quarter following the return, undrawn,
or cancellation of such Letter of Credit and Borrower's receipt of notice from
Administrative Agent.

           (g) The parties hereto acknowledge and agree that, immediately upon
notice from Administrative Agent of any drawing under a Letter of Credit, each
Bank shall, notwithstanding the existence of a Default or Event of Default or
the non-satisfaction of any conditions precedent to the making of an advance of
the Loans, advance proceeds of its Ratable Loan, in an amount equal to its Pro
Rata Share of such drawing, which advance shall be made to Administrative Agent
to reimburse Administrative Agent, for its own account, for such drawing. Each
of the Banks further acknowledges that its obligation to fund its Pro Rata Share
of drawings under Letters of Credit as aforesaid shall survive the Banks'
termination of this Agreement or enforcement of remedies hereunder or under the
other Loan Documents.

           (h) Borrower agrees, upon the occurrence of an Event of Default and
at the written request of Administrative Agent, (1) to deposit with
Administrative Agent cash collateral in the amount of all the outstanding
Letters of Credit, which cash collateral shall be held by Administrative Agent
as security for Borrower's obligations in connection with the Letters of Credit
and (2) to execute and deliver to Administrative Agent such documents as
Administrative Agent reasonably requests to confirm and perfect the assignment
of such cash collateral to Administrative Agent.

           Section 2.17   Intentionally Omitted.

           Section 2.18   Swing Loans. (a) During the term of this Agreement,
the Swing Lender agrees, on the terms and conditions set forth in this
Agreement, to make advances to Borrower pursuant to this Section from time to
time in amounts such that (i) the aggregate of such advance and amount of Swing
Loans theretofore advanced and still outstanding does not at any time exceed the
Swing Loan Commitment and (ii) the amount of such advance does not exceed the
Available Total Loan Commitment. Each advance under this Section shall be in an
aggregate principal amount of $1,000,000 or a larger multiple of $100,000
(except that any such advance may be in the aggregate available amount of Swing
Loans determined in accordance with the immediately preceding sentence). With
the foregoing limits, Borrower may borrow under this Section, repay or, to the
extent permitted by Section 2.09, prepay Swing Loans and reborrow under this
Section at any time during the term of this Agreement.

           (b) The Swing Lender shall, on behalf of Borrower (which hereby
irrevocably directs the Swing Lender to act on its behalf), on notice given by
the Swing Lender no later than 1:00 p.m. (New York time) on the Banking Day
immediately following the funding of any Swing Loan, request each Bank to make,
and each Bank hereby agrees to make, an advance of its Ratable Loan, in an
amount (with respect to each Bank, its "Swing Loan Refund Amount") equal to such
Bank's Pro Rata Share of the aggregate principal amount of the Swing Loans (the
"Refunded Swing Loans") outstanding on the date of such notice, to repay the
Swing Lender. Unless any of the events described in paragraph (5) of Section
9.01 with respect to Borrower shall have occurred and be continuing (in which
case the procedures of paragraph (c) of this Section shall apply), each Bank
shall make such advance of its Ratable Loan available to Administrative Agent at
Administrative Agent's Office in immediately available funds, not later than
1:00 p.m. (New York time), on the third Banking Day immediately following the
date of such notice. Administrative Agent shall pay the proceeds of such advance
of Ratable Loans to the Swing Lender, which shall immediately apply such
proceeds to repay Refunded Swing Loans. Effective on the day such advances of
Ratable Loans are made, the portion of the Swing Loans so paid shall no longer
be outstanding as Swing Loans, shall no longer be due as Swing Loans under the
Swing Loan Note held by the Swing Lender, and shall be due as Ratable Loans
under the respective Ratable Loan Notes issued to the Banks (including the Swing
Lender). Borrower authorizes the Swing Lender to charge Borrower's accounts with
Administrative Agent (up to the amount available in each such accounts) in order
to immediately pay the amount of such Refunded Swing Loans to the extent amounts
received from the Banks are not sufficient to repay in full such Refunded Swing
Loans.

           (c) If, prior to the time advances of Ratable Loans would have
otherwise been made pursuant to paragraph (b) of this Section, one of the events
described in paragraph (5) of Section 9.01 with respect to the Borrower shall
have occurred and be continuing, each Bank shall, on the date such advances were
to have been made pursuant to the notice referred to in paragraph (b) of this
Section (the "Refunding Date"), purchase an undivided participating interest in
the Swing Loans in an amount equal to such Bank's Swing Loan Refund Amount. On
the Refunding Date, each Bank shall transfer to the Swing Lender, in immediately
available funds, such Bank's Swing Loan Refund Amount, and upon receipt thereof,
the Swing Lender shall deliver to such Bank a Swing Loan participation
certificate dated the date of the Swing Lender's receipt of such funds and in
the Swing Loan Refund Amount of such Bank.


                                       29
<PAGE>   35


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

           (e) Each Bank's obligation to transfer the amount of a Loan to the
Swing Lender as provided in paragraph (b) of this Section or to purchase a
participating interest pursuant to paragraph (c) of this Section shall be
absolute and unconditional and shall not be affected by any circumstance,
including, without limitation, (i) any set-off, counterclaim, recoupment,
defense or other right which such Bank, Borrower or any other Person may have
against the Swing Lender or any other Person, (ii) the occurrence or continuance
of a Default or an Event of Default, the termination or reduction of the Loan
Commitments or the non-satisfaction of any condition precedent to the making of
any advance of the Loans, (iii) any adverse change in the condition (financial
or otherwise) of Borrower or any other Person, (iv) any breach of this Agreement
by Borrower, any other Bank or any other Person or (v) any other circumstance,
happening or event whatsoever, whether or not similar to any of the foregoing.

           (f) Notwithstanding anything above in this Section or elsewhere in
this Agreement to the contrary, in the event that the Swing Lender funds a Swing
Loan hereunder when it has actual knowledge that a monetary Default, or material
Event of Default (which, for the avoidance of doubt shall include any violation
of any provision of Article VII or Article VIII) has occurred and is continuing,
the Banks shall have the option to make Ratable Loans to fund their ratable
shares of such Swing Loan as contemplated in paragraph (b) of this Section or to
purchase participations as contemplated in paragraph (c) of this Section.

           (g) For purposes of Article III, Swing Loans shall be deemed to be
LIBOR Loans.

           Section 2.19   Extension Of Maturity. (a) Borrower shall have the
option (the "Extension Option") to extend the original Maturity Date for a
period of one (1) year. Subject to the conditions set forth below, Borrower may
exercise the Extension Option by delivering a written notice to Administrative
Agent not less than one hundred twenty (120) days prior to the original Maturity
Date (a "Notice to Extend"), stating that Borrower has elected to extend the
original Maturity Date for one (1) year. Borrower's delivery of the Notice to
Extend shall be irrevocable and Borrower's right to exercise the Extension
Option shall be subject to the following terms and conditions: (i) there shall
exist no Event of Default on both the date Borrower delivers the Notice to
Extend to Administrative Agent and on the original Maturity Date, (ii) Borrower
shall have paid to Administrative Agent for the account of each Bank an
extension fee equal to 0.10% of such Bank's Loan Commitment simultaneously with
delivery of the Notice to Extend and (iii) Borrower shall be in compliance with
the covenants contained in Articles VII and VIII.


                                       30
<PAGE>   36

           (b) If Borrower shall have effectively exercised the Extension Option
pursuant to paragraph (a) above, Borrower may request a one-year extension of
the Maturity Date, as so extended, by delivering a written request therefor to
Administrative Agent not more than six (6) months or less than one hundred
twenty (120) days prior to such Maturity Date (a "Request to Extend").
Administrative Agent shall notify the Banks of its receipt of the Request to
Extend and each Bank shall give notice in writing to Administrative Agent not
less than ninety (90) days prior to the Maturity Date to be extended of such
Bank's acceptance or rejection of such Request to Extend. If all the Banks shall
have notified Administrative Agent on or prior to the date which is ninety (90)
days prior to the Maturity Date to be extended that they accept such request,
the Maturity Date shall be extended for one (1) year. If any Bank shall not have
notified Administrative Agent on or prior to the date which is ninety (90) days
prior to the Maturity Date to be extended that it accepts such Request to
Extend, the Maturity Date shall not be extended. Administrative Agent shall
notify Borrower and the Banks whether the Request to Extend has been accepted by
all of the Banks. If the Request to Extend is accepted by all of the Banks, the
Maturity Date shall be extended for one (1) year. The effectiveness of the
acceptance of the Request to Extend shall be subject to the following terms and
conditions: (i) there shall exist no Event of Default on both the date Borrower
delivers the Request to Extend to Administrative Agent and on the Maturity Date
to be extended, (ii) Borrower shall pay to Administrative Agent for the account
of each Bank an extension fee equal to 0.10% of such Bank's Loan Commitment
within five (5) Banking Days after receipt of notice from Administrative Agent
that the Request to Extend has been accepted by all of the Banks and (iii)
Borrower shall be in compliance with the covenants contained in Articles VII and
VIII.

                                  ARTICLE III

                       YIELD PROTECTION; ILLEGALITY, ETC.

           Section 3.01   Additional Costs. Borrower shall pay directly to each
Bank from time to time on demand such amounts as such Bank may determine to be
necessary to compensate it for any increased costs which such Bank determines
are attributable to its making or maintaining a LIBOR Loan or a LIBOR Bid Rate
Loan, or its obligation to make or maintain a LIBOR Loan or a LIBOR Bid Rate
Loan, or its obligation to Convert a Base Rate Loan to a LIBOR Loan hereunder,
or any reduction in any amount receivable by such Bank hereunder in respect of
its LIBOR Loan or LIBOR Bid Rate Loan(s) or such obligations (such increases in
costs and reductions in amounts receivable being herein called "Additional
Costs"), in each case resulting from any Regulatory Change which:

           (1) changes the basis of taxation of any amounts payable to such Bank
     under this Agreement or the Notes in respect of any such LIBOR Loan or
     LIBOR Bid Rate Loan (other than changes in the rate of general corporate,
     franchise, branch profit, net income or other income tax imposed on such
     Bank or its Applicable Lending Office by the jurisdiction in which such
     Bank has its principal office or such Applicable Lending Office); or

           (2) (other than to the extent the LIBOR Reserve Requirement is taken
     into account in determining the LIBOR Rate at the commencement of the
     applicable Interest Period) imposes or modifies any reserve, special
     deposit, deposit insurance or


                                       31
<PAGE>   37


     assessment, minimum capital, capital ratio or similar requirements relating
     to any extensions of credit or other assets of, or any deposits with or
     other liabilities of, such Bank (including any LIBOR Loan or LIBOR Bid Rate
     Loan or any deposits referred to in the definition of "LIBOR Interest Rate"
     in Section 1.01), or any commitment of such Bank (including such Bank's
     Loan Commitment hereunder); or

           (3) imposes any other condition affecting this Agreement or the Notes
(or any of such extensions of credit or liabilities).

           Without limiting the effect of the provisions of the first paragraph
of this Section, in the event that, by reason of any Regulatory Change, any Bank
either (1) incurs Additional Costs based on or measured by the excess above a
specified level of the amount of a category of deposits of other liabilities of
such Bank which includes deposits by reference to which the LIBOR Interest Rate
is determined as provided in this Agreement or a category of extensions of
credit or other assets of such Bank which includes loans based on the LIBOR
Interest Rate or (2) becomes subject to restrictions on the amount of such a
category of liabilities or assets which it may hold, then, if such Bank so
elects by notice to Borrower (with a copy to Administrative Agent), the
obligation of such Bank to permit Elections of, to Continue, or to Convert Base
Rate Loans into, LIBOR Loans shall be suspended (in which case the provisions of
Section 3.04 shall be applicable) until such Regulatory Change ceases to be in
effect.

           Determinations and allocations by a Bank for purposes of this Section
of the effect of any Regulatory Change pursuant to the first or second paragraph
of this Section, on its costs or rate of return of making or maintaining its
Loan or portions thereof or on amounts receivable by it in respect of its Loan
or portions thereof, and the amounts required to compensate such Bank under this
Section, shall be included in a calculation of such amounts given to Borrower
and shall be conclusive absent manifest error.

           Section 3.02   Limitation on Types of Loans. Anything herein to the
contrary notwithstanding, if, on or prior to the determination of the LIBOR
Interest Rate for any Interest Period:

           (1) Administrative Agent reasonably determines (which determination
     shall be conclusive), and provides Borrower, in writing, with reasonable
     detail supporting such determination, that quotations of interest rates for
     the relevant deposits referred to in the definition of "LIBOR Interest
     Rate" in Section 1.01 are not being provided in the relevant amounts or for
     the relevant maturities for purposes of determining rates of interest for
     the LIBOR Loans or LIBOR Bid Rate Loans as provided in this Agreement; or

           (2) a Bank reasonably determines (which determination shall be
     conclusive), and provides Borrower, in writing, with reasonable detail
     supporting such determination, and promptly notifies Administrative Agent
     that the relevant rates of interest referred to in the definition of "LIBOR
     Interest Rate" in Section 1.01 upon the basis of which the rate of interest
     for LIBOR Loans or LIBOR Bid Rate Loans for such Interest Period is to be
     determined do not adequately cover the cost to such Bank of making or
     maintaining such LIBOR Loan or LIBOR Bid Rate Loan for such Interest
     Period;


                                       32
<PAGE>   38


then Administrative Agent shall give Borrower prompt notice thereof, and so long
as such condition remains in effect, the Banks (or, in the case of the
circumstances described in clause (2) above, the affected Bank) shall be under
no obligation to permit Elections of LIBOR Loans, to Convert Base Rate Loans
into LIBOR Loans or to Continue LIBOR Loans and Borrower shall, on the last
day(s) of the then current Interest Period(s) for the affected outstanding LIBOR
Loans or LIBOR Bid Rate Loans, either (x) prepay the affected LIBOR Loans or
LIBOR Bid Rate Loans or (y) Convert the affected LIBOR Loans into Base Rate
Loans in accordance with Section 2.12 or convert the rate of interest under the
affected LIBOR Bid Rate Loans to the rate applicable to Base Rate Loans by
following the same procedures as are applicable for Conversions into Base Rate
Loans set forth in Section 2.12.

           Section 3.03   Illegality. Notwithstanding any other provision of
this Agreement, in the event that it becomes unlawful for any Bank or its
Applicable Lending Office to honor its obligation to make or maintain a LIBOR
Loan or LIBOR Bid Rate Loan hereunder, to allow Elections of a LIBOR Loan or to
Convert a Base Rate Loan into a LIBOR Loan, then such Bank shall promptly notify
Administrative Agent and Borrower thereof and such Bank's obligation to make or
maintain a LIBOR Loan or LIBOR Bid Rate Loan, or to permit Elections of, to
Continue, or to Convert its Base Rate Loan into, a LIBOR Loan shall be suspended
(in which case the provisions of Section 3.04 shall be applicable) until such
time as such Bank may again make and maintain a LIBOR Loan or a LIBOR Bid Rate
Loan.

           Section 3.04   Treatment of Affected Loans. If the obligations of any
Bank to make or maintain a LIBOR Loan or a LIBOR Bid Rate Loan, or to permit an
Election of a LIBOR Loan, to Continue its LIBOR Loan, or to Convert its Base
Rate Loan into a LIBOR Loan, are suspended pursuant to Sections 3.01 or 3.03
(each LIBOR Loan or LIBOR Bid Rate Loan so affected being herein called an
"Affected Loan"), such Bank's Affected Loan shall be automatically Converted
into a Base Rate Loan (or, in the case of an Affected Loan that is a LIBOR Bid
Rate Loan, the interest rate thereon shall be converted to the rate applicable
to Base Rate Loans) on the last day of the then current Interest Period for the
Affected Loan (or, in the case of a Conversion (or conversion) required by
Sections 3.01 or 3.03, on such earlier date as such Bank may specify to
Borrower).

           To the extent that such Bank's Affected Loan has been so Converted
(or the interest rate thereon so converted), all payments and prepayments of
principal which would otherwise be applied to such Bank's Affected Loan shall be
applied instead to its Base Rate Loan (or to its LIBOR Bid Rate Loan bearing
interest at the converted rate) and such Bank shall have no obligation to
Convert its Base Rate Loan into a LIBOR Loan.

           Section 3.05   Certain Compensation. Other than in connection with a
Conversion of an Affected Loan, Borrower shall pay to Administrative Agent for
the account of the applicable Bank, upon the request of such Bank through
Administrative Agent which request includes a calculation of the amount(s) due,
such amount or amounts as shall be sufficient (in the reasonable opinion of such
Bank) to compensate it for any loss, cost or expense which such Bank reasonably
determines is attributable to:

           (1) any payment or prepayment of a LIBOR Loan or Bid Rate Loan made
     by such Bank, or any Conversion or Continuation of a LIBOR Loan made by
     such Bank, in any


                                       33
<PAGE>   39


     such case on a date other than the last day of an applicable Interest
     Period, whether by reason of acceleration or otherwise; or

           (2) any failure by Borrower for any reason to Convert or Continue a
     LIBOR Loan to be Converted or Continued by such Bank on the date specified
     there for in the relevant notice under Section 2.14; or

           (3) any failure by Borrower to borrow (or to qualify for a borrowing
     of) a LIBOR Loan or Bid Rate Loan which would otherwise be made hereunder
     on the date specified in the relevant Election notice under Section 2.14 or
     Bid Rate Quote acceptance under Section 2.02(e) given or submitted by
     Borrower.

           Without limiting the foregoing, such compensation shall include any
loss incurred in obtaining, liquidating or employing deposits from third
parties, but excluding loss of margin for the period after the date of such
payment, prepayment, Conversion or Continuation (or failure to Convert, Continue
or borrow). A determination of any Bank as to the amounts payable pursuant to
this Section shall be conclusive absent manifest error.

           Section 3.06   Capital Adequacy. If any Bank shall have determined
that, after the date hereof, the adoption of any applicable law, rule or
regulation regarding capital adequacy, or any change therein, or any change in
the interpretation or administration thereof by any Governmental Authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or any request or directive regarding capital adequacy
(whether or not having the force of law) of any such Governmental Authority,
central bank or comparable agency, has or would have the effect of reducing the
rate of return on capital of such Bank (or its Parent) as a consequence of such
Bank's obligations hereunder to a level below that which such Bank (or its
Parent) could have achieved but for such adoption, change, request or directive
(taking into consideration its policies with respect to capital adequacy) by an
amount deemed by such Bank to be material, then from time to time, within
fifteen (15) days after demand by such Bank (with a copy to Administrative
Agent), Borrower shall pay to such Bank such additional amount or amounts as
will compensate such Bank (or its Parent) for such reduction. A certificate of
any Bank claiming compensation under this Section, setting forth in reasonable
detail the basis therefor, shall be conclusive absent manifest error.

           Section 3.07   Substitution of Banks. If any Bank (an "Affected
Bank") (1) makes demand upon Borrower for (or if Borrower is otherwise required
to pay) Additional Costs pursuant to Section 3.01 or (2) is unable to make or
maintain a LIBOR Loan or LIBOR Bid Rate Loan as a result of a condition
described in Section 3.03 or clause (2) of Section 3.02, Borrower may, within
ninety (90) days of receipt of such demand or notice (or the occurrence of such
other event causing Borrower to be required to pay Additional Costs or causing
said Section 3.03 or clause (2) of Section 3.02 to be applicable), as the case
may be, give written notice (a "Replacement Notice") to Administrative Agent and
to each Bank of Borrower's intention either (x) to prepay in full the Affected
Bank's Note and to terminate the Affected Bank's entire Loan Commitment or (y)
to replace the Affected Bank with another financial institution (the
"Replacement Bank") designated in such Replacement Notice.


                                       34
<PAGE>   40


           In the event Borrower opts to give the notice provided for in clause
(x) above, and if the Affected Bank shall not agree within thirty (30) days of
its receipt thereof to waive the payment of the Additional Costs in question or
the effect of the circumstances described in Section 3.03 or clause (2) of
Section 3.02, then, so long as no Default or Event of Default shall exist,
Borrower may (notwithstanding the provisions of clause (2) of Section 2.10(a))
terminate the Affected Bank's entire Loan Commitment, provided that in
connection therewith it pays to the Affected Bank all outstanding principal and
accrued and unpaid interest under the Affected Bank's Note, together with all
other amounts, if any, due from Borrower to the Affected Bank, including all
amounts properly demanded and unreimbursed under Sections 3.01 and 3.05.

           In the event Borrower opts to give the notice provided for in clause
(y) above, and if (i) Administrative Agent shall, within thirty (30) days of its
receipt of the Replacement Notice, notify Borrower and each Bank in writing that
the Replacement Bank is reasonably satisfactory to Administrative Agent and (ii)
the Affected Bank shall not, prior to the end of such thirty (30)-day period,
agree to waive the payment of the Additional Costs in question or the effect of
the circumstances described in Section 3.03 or clause (2) of Section 3.02, then
the Affected Bank shall, so long as no Default or Event of Default shall exist,
assign its Note and all of its rights and obligations under this Agreement to
the Replacement Bank, and the Replacement Bank shall assume all of the Affected
Bank's rights and obligations, pursuant to an agreement, substantially in the
form of an Assignment and Assumption Agreement, executed by the Affected Bank
and the Replacement Bank. In connection with such assignment and assumption, the
Replacement Bank shall pay to the Affected Bank an amount equal to the
outstanding principal amount under the Affected Bank's Note plus all interest
accrued thereon, plus all other amounts, if any (other than the Additional Costs
in question), then due and payable to the Affected Bank; provided, however, that
prior to or simultaneously with any such assignment and assumption, Borrower
shall have paid to such Affected Bank all amounts properly demanded and
unreimbursed under Sections 3.01 and 3.05. Upon the effective date of such
assignment and assumption, the Replacement Bank shall become a Bank Party to
this Agreement and shall have all the rights and obligations of a Bank as set
forth in such Assignment and Assumption Agreement, and the Affected Bank shall
be released from its obligations hereunder, and no further consent or action by
any party shall be required. Upon the consummation of any assignment pursuant to
this Section, a substitute Ratable Loan Note (and, if applicable, Swing Loan
Note) shall be issued to the Replacement Bank by Borrower, in exchange for the
return of the Affected Bank's Ratable Loan Note (and, if applicable, Swing Loan
Note). The obligations evidenced by such substitute note shall constitute
"Obligations" for all purposes of this Agreement and the other Loan Documents.
In connection with Borrower's execution of substitute notes as aforesaid,
Borrower shall deliver to Administrative Agent evidence, satisfactory to
Administrative Agent, of all requisite corporate action to authorize Borrower's
execution and delivery of the substitute notes and any related documents. If the
Replacement Bank is not incorporated under the laws of the United States of
America or a state thereof, it shall, prior to the first date on which interest
or fees are payable hereunder for its account, deliver to Borrower and
Administrative Agent certification as to exemption from deduction or withholding
of any United States federal income taxes in accordance with Section 10.13. Each
Replacement Bank shall be deemed to have made the representations contained in,
and shall be bound by the provisions of, Section 10.13.

modifications to the Loan Documents as shall be reasonably required in
connection with and to effectuate the foregoing.

           Section 3.08   Applicability. The provisions of this Article III
shall be applied to Borrower so as not to discriminate against Borrower
vis-a-vis similarly situated customers of the Banks.

           Borrower represents and warrants to Administrative Agent and each
Bank as follows:

           Section 5.01   Due Organization. Borrower is duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
organization, has the power and authority to own its assets and to transact the
business in which it is now engaged, and, if applicable, is duly qualified for
the conduct of business and in good standing under the laws of each other
jurisdiction in which such qualification is required and where the failure to be

performed by Borrower of the Loan Documents does not and will not (a) require

or require, the creation or imposition of any Lien, upon or with respect to any

Borrower's knowledge, cause it to be in default under any such Law, order, writ,
judgment, injunction, decree, determination or award or any such indenture,
agreement, lease or instrument; to the best of its knowledge, Borrower is in
material compliance with all Laws applicable to it and its properties.

           Section 5.03   Legally Enforceable Agreements. Each Loan Document is
a legal, valid and binding obligation of Borrower, enforceable against Borrower
in accordance with its terms, except to the extent that such enforcement may be
limited by applicable bankruptcy, insolvency and other similar laws affecting
creditors' rights generally.

           Section 5.04   Litigation. There are no actions, suits or proceedings
pending or, to its knowledge, threatened against Borrower or any of its
Affiliates before any court or arbitrator or any Governmental Authority which
are reasonably likely to result in a Material Adverse Change.

           Section 5.05   Good Title to Properties. Borrower and each of its
Material Affiliates have good, marketable and legal title to all of the
properties and assets each of them purports to own (including, without
limitation, those reflected in the Consolidated Financial Statements referred to
in Section 5.13), only with exceptions which do not materially detract from the
value of such property or assets or the use thereof in Borrower's and such
Material Affiliate's business, and except to the extent that any such properties
and assets have been encumbered or disposed of since the date of such financial
statements without violating any of the covenants contained in Article VII or
elsewhere in this Agreement. Borrower and its Material Affiliates enjoy peaceful
and undisturbed possession of all leased property necessary in any material
respect in the conduct of their respective businesses. All such leases are valid
and subsisting and are in full force and effect.

           Section 5.06   Taxes. Borrower has filed all tax returns (federal,
state and local) required to be filed and has paid all taxes, assessments and
governmental charges and levies due and payable without the imposition of a
penalty, including interest and penalties, except to the extent they are the
subject of a Good Faith Contest.

           Section 5.07   ERISA. Borrower is in compliance in all material
respects with all applicable provisions of ERISA. Neither a Reportable Event nor
a Prohibited Transaction has occurred with respect to any Plan which could
result in liability of Borrower; no notice of intent to terminate a Plan has
been filed nor has any Plan been terminated within the past five (5) years; no
circumstance exists which constitutes grounds under Section 4042 of ERISA
entitling the PBGC to institute proceedings to terminate, or appoint a trustee
to administer, a Plan, nor has the PBGC instituted any such proceedings;
Borrower and the ERISA Affiliates have not completely or partially withdrawn
under Sections 4201 or 4204 of ERISA from a Multiemployer Plan; Borrower and the
ERISA Affiliates have met the minimum funding requirements of Section 412 of the
Code and Section 302 of ERISA of each with respect to the Plans of each and
there is no material "Unfunded Current Liability" (as such quoted term is
defined in ERISA) with respect to any Plan established or maintained by each;
and Borrower and the ERISA Affiliates have not incurred any liability to the
PBGC under ERISA (other than for the payment of premiums under Section 4007 of
ERISA). No part of the funds to be used by Borrower in satisfaction of its
obligations under this Agreement constitute "plan assets" of any "employee
benefit plan" within the meaning of ERISA or of any "plan" within the meaning of
Section 4975(e)(1) of the Code, as interpreted by the Internal Revenue Service
and the U.S. Department of Labor in rules, regulations, releases, bulletins or
as interpreted under applicable case law.

Borrower and each of its Material Affiliates have satisfied all judgments which
are not being appealed or which are not fully covered by insurance, and are not
in default with respect to any judgment, order, writ, injunction, decree, rule
or regulation of any court, arbitrator or federal, state, municipal or other
Governmental Authority, commission, board, bureau, agency or instrumentality,
domestic or foreign.

           Section 5.09   No Defaults on Other Agreements. Except as disclosed

regulation under the Investment Company Act of 1940 or any statute or regulation
limiting its ability to incur indebtedness for money borrowed as contemplated
hereby.

           Section 5.11   Environmental Protection. To the best of Borrower's
knowledge, none of Borrower's or its Material Affiliates' properties contains
any Hazardous Materials that, under any Environmental Law currently in effect,
(1) would impose liability on Borrower that is likely to result in a Material
Adverse Change, or (2) is likely to result in the imposition of a Lien on any
assets of Borrower or its Material Affiliates, in each case if not properly
handled in accordance with applicable Law or not covered by insurance or a bond,
in either case reasonably satisfactory to the Required Banks. To the best of
Borrower's knowledge, neither it nor any of its Material Affiliates is in
material violation of, or subject to any existing, pending or threatened
material investigation or proceeding by any Governmental Authority under any
Environmental Law.

           Section 5.12   Solvency. Borrower is, and upon consummation of the

Statements of Avalon, Bay and Borrower most recently delivered to the Banks
pursuant to the terms of this Agreement are in all material respects complete
and correct and fairly present the financial condition of the subjects thereof

accordance with GAAP. There has been no Material Adverse Change since the date
of such most recently delivered Consolidated Financial Statements.

the laws of the jurisdiction of its formation. As to each Material Affiliate,

beneficial interest therein, and the type of business in which it is primarily
engaged, are set forth on said EXHIBIT C. Borrower and each of its Material


                                       40
<PAGE>   46


Affiliates have the power to own their respective properties and to carry on
their respective businesses now being conducted. Each Material Affiliate is duly
qualified as a foreign corporation to do business and is in good standing in
every jurisdiction in which the nature of the respective businesses conducted by
it or its respective properties, owned or held under lease, make such
qualification necessary and where the failure to be so qualified would cause a
Material Adverse Change.

           Section 5.15   Insurance. Borrower and each of its Material
Affiliates have in force paid insurance with financially sound and reputable
insurance companies or associations in such amounts and covering such risks as
are usually carried by companies engaged in the same type of business and

Agreement nor any documents, financial statements, reports, notices, schedules,
certificates, statements or other writings furnished by or on behalf of Borrower
to Administrative Agent or any Bank in connection with the negotiation of this
Agreement or the consummation of the transactions contemplated hereby, or
required herein to be furnished by or on behalf of Borrower (other than
projections which are made by Borrower in good faith), contains any untrue or
misleading statement of a material fact or omits a material fact necessary to
make the statements herein or therein not misleading. To the best of Borrower's
knowledge, there is no fact which Borrower has not disclosed to Administrative
Agent and the Banks in writing which materially affects adversely nor, so far as
Borrower can now foresee, will materially affect adversely the business affairs
or financial condition of Borrower or the ability of Borrower to perform this
Agreement and the other Loan Documents.

           Section 5.17   Corporate Merger and Termination of Other Credit
Facilities. The merger of Avalon and Bay into Borrower has been effectively
completed in accordance with all applicable Laws, and any and all existing
credit facilities of Avalon and Bay have been effectively terminated.

Affiliates to:

           Section 6.01   Maintenance of Existence. Preserve and maintain its

qualified in such other jurisdictions is not likely to result in a Material
Adverse Change.

place as of the Closing Date is acceptable to Administrative Agent.

(12)-month period, such property's contribution to Combined EBITDA shall be

           (2) If any representation or warranty made by Borrower in this

contemplated hereby and such failure under this clause (b) shall remain
unremedied for thirty (30) consecutive calendar days after notice thereof (or
such shorter cure period as may be expressly prescribed in the applicable
document); provided, however, that if any such default under clause (b) above
cannot by its nature be cured within such thirty (30) day, or shorter, as the
case may be, grace period and so long as Borrower shall have commenced cure
within such thirty (30) day, or shorter, as the case may be, grace period and
shall, at all times thereafter, diligently prosecute the same to completion,
Borrower shall have an additional period, not to exceed sixty (60) days, to cure
such default; in no event, however, is the foregoing intended to effect an
extension of the Maturity Date; or

           (4) If Borrower shall fail (a) to pay any Recourse Debt (other than
the payment obligations described in paragraph (1) of this Section) in any
amount, or any Debt (other than Recourse Debt) in an amount equal to or greater
than $50,000,000, in any such case when due (whether by scheduled maturity,
required prepayment, acceleration, demand, or otherwise) after the expiration of
any applicable grace period, or (b) to perform or observe any material term,
covenant, or condition under any agreement or instrument relating to any such
Debt, when required to be performed or observed, if the effect of such failure
to perform or observe is to accelerate, or to permit the acceleration of, after
the giving of notice or the lapse of time, or both (other than in cases where,
in the judgment of the Required Banks, meaningful discussions likely to result
in (i) a waiver or cure of the failure to perform or observe, or (ii) otherwise

money in excess of $10,000,000 (excluding any such judgments, decrees or orders
which are fully covered by insurance) in the aggregate shall be rendered against

ERISA; or (e) complete or partial withdrawal under Section 4201 or 4204 of ERISA
from a Multiemployer Plan or the reorganization, insolvency, or termination of
any Multiemployer Plan; and in each case above, if such event or conditions, if

penalty, or other liability to a Plan, Multiemployer Plan, the PBGC or otherwise
(or any combination thereof) which in the aggregate exceeds or is likely to
exceed $50,000; or

           (8) If at any time Borrower is not a qualified real estate investment

           (10)   If, in the reasonable judgment of all of the Banks (and the

           (11)   If there shall occur a change in the majority of the Board of

           Section 9.02   Remedies. If any Event of Default shall occur and be
continuing, Administrative Agent shall, upon request of the Majority Banks, by
notice to Borrower, (1) declare the outstanding balance of the Notes, all
interest thereon, and all other amounts payable under this Agreement to be
forthwith due and payable, whereupon such balance, all such interest, and all
such amounts due under this Agreement and under any other Loan Document shall
become and be forthwith due and payable, without presentment, demand, protest,
or further


                                       48
<PAGE>   54


notice of any kind, all of which are hereby expressly waived by Borrower; and/or
(2) exercise any remedies provided in any of the Loan Documents or by law.
Notwithstanding the foregoing, if an Event of Default under Section 9.01(10)
shall occur and be continuing, Administrative Agent shall not be entitled to
exercise the foregoing remedies until (1) it has received a written notice from
all of the Banks (the "Unanimous Bank Notices") (i) requesting Administrative
Agent exercise such remedies and (ii) indicating each Bank's conclusion in its
reasonable judgment that a Material Adverse Change has occurred and (2)
Administrative Agent has provided notice to Borrower, together with copies of

                                   ARTICLE X

                   ADMINISTRATIVE AGENT; RELATIONS AMONG BANKS

           Section 10.01  Appointment, Powers and Immunities of Administrative
Agent. Each Bank hereby irrevocably appoints and authorizes Administrative Agent
to act as its agent hereunder and under any other Loan Document with such powers
as are specifically delegated to Administrative Agent by the terms of this
Agreement and any other Loan Document, together with such other powers as are
reasonably incidental thereto. Administrative Agent shall have no duties or
responsibilities except those expressly set forth in this Agreement and any
other Loan Document or required by law, and shall not by reason of this
Agreement be a fiduciary or trustee for any Bank except to the extent that
Administrative Agent acts as an agent with respect to the receipt or payment of
funds (nor shall Administrative Agent have any fiduciary duty to Borrower nor
shall any Bank have any fiduciary duty to Borrower or to any other Bank). No
implied covenants, responsibilities, duties, obligations or liabilities shall be
read into this Agreement or otherwise exist against Administrative Agent.
Neither Administrative Agent nor any of its directors, officers, employees,
attorneys-in-fact or affiliates shall be responsible to the Banks for any
recitals, statements, representations or warranties made by Borrower or any
officer, partner or official of Borrower or any other Person contained in this
Agreement or any other Loan Document, or in any certificate or other document or
instrument referred to or provided for in, or received by any of them under,
this Agreement or any other Loan Document, or for the value, legality, validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement or
any other Loan Document or any other document or instrument referred to or
provided for herein or therein, for the perfection or priority of any Lien
securing the Obligations or for any failure by Borrower to perform any of its
obligations hereunder or thereunder. Administrative Agent may employ agents and
attorneys-in-fact and shall not be responsible, except as to money or securities
received by it or its authorized agents, for the negligence or misconduct of any
such agents or attorneys-in-fact selected by it with reasonable care. Neither
Administrative Agent nor any of its directors, officers, employees,
attorneys-in-fact, agents or affiliates shall be liable or responsible for any
action taken or omitted to be taken by it or them hereunder or under any other
Loan Document or in connection herewith or therewith, except for its or their
own gross negligence or willful misconduct. Borrower shall pay any fee agreed to
by Borrower and Administrative Agent with respect to Administrative Agent's
services hereunder.

           Section 10.02  Reliance by Administrative Agent. Administrative Agent
shall be entitled to rely upon any certification, notice or other communication
(including any thereof by telephone, telex, telegram or cable) believed by it to
be genuine and correct and to have been signed or sent by or on behalf of the
proper Person or Persons, and upon advice and statements


                                       49
<PAGE>   55


of legal counsel, independent accountants and other experts selected by
Administrative Agent. Administrative Agent may deem and treat each Bank as the
holder of the Loan made by it for all purposes hereof and shall not be required
to deal with any Person who has acquired a participation in any Loan or
participation from a Bank. As to any matters not expressly provided for by this
Agreement or any other Loan Document, Administrative Agent shall in all cases be
fully protected in acting, or in refraining from acting, hereunder in accordance
with instructions signed by the Required Banks, and such instructions of the
Required Banks and any action taken or failure to act pursuant thereto shall be
binding on all of the Banks and any other holder of all or any portion of any
Loan or participation.

           Section 10.03  Defaults. Administrative Agent shall not be deemed to
have knowledge of the occurrence of a Default or Event of Default unless
Administrative Agent has received notice from a Bank or Borrower specifying such
Default or Event of Default and stating that such notice is a "Notice of
Default." In the event that Administrative Agent receives such a notice of the
occurrence of a Default or Event of Default, Administrative Agent shall give
prompt notice thereof to the Banks. Administrative Agent, following consultation
with the Banks, shall (subject to Section 10.07) take such action with respect
to such Default or Event of Default which is continuing as shall be directed by
the Majority Banks; provided that, unless and until Administrative Agent shall
have received such directions, Administrative Agent may take such action, or
refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable in the best interest of the Banks; and
provided further that Administrative Agent shall not send a notice of Default or
acceleration to Borrower without the approval of the Majority Banks. In no event
shall Administrative Agent be required to take any such action which it
determines to be contrary to Law or to the Loan Documents. Each of the Banks
acknowledges and agrees that no individual Bank may separately enforce or
exercise any of the provisions of any of the Loan Documents, including, without
limitation, the Notes, other than through Administrative Agent.

           Section 10.04  Rights of Administrative Agent as a Bank. With respect
to its Loan Commitment and the Loan provided by it, Administrative Agent in its
capacity as a Bank hereunder shall have the same rights and powers hereunder as
any other Bank and may exercise the same as though it were not acting as
Administrative Agent, and the term "Bank" or "Banks" shall, unless the context
otherwise indicates, include Administrative Agent in its capacity as a Bank.
Administrative Agent and its Affiliates may (without having to account therefor
to any Bank) accept deposits from, lend money to (on a secured or unsecured
basis), and generally engage in any kind of banking, trust or other business
with Borrower (and any Affiliates of Borrower) as if it were not acting as
Administrative Agent.

           Section 10.05  Indemnification of Administrative Agent. Each Bank
agrees to indemnify Administrative Agent (to the extent not reimbursed under
Section 12.04 or under the applicable provisions of any other Loan Document, but
without limiting the obligations of Borrower under Section 12.04 or such
provisions), for its Pro Rata Share of any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind and nature whatsoever which may be imposed on,
incurred by or asserted against Administrative Agent in any way relating to or
arising out of this Agreement, any other Loan Document or any other documents
contemplated by or referred to herein or the transactions contemplated hereby or
thereby (including, without limitation, the costs and


                                       50
<PAGE>   56


expenses which Borrower is obligated to pay under Section 12.04) or under the
applicable provisions of any other Loan Document or the enforcement of any of
the terms hereof or thereof or of any such other documents or instruments;
provided that no Bank shall be liable for (1) any of the foregoing to the extent
they arise from the gross negligence or willful misconduct of the party to be
indemnified, (2) any loss of principal or interest with respect to
Administrative Agent's Loan or (3) any loss suffered by Administrative Agent in
connection with a swap or other interest rate hedging arrangement entered into
with Borrower.

           Section 10.06  Non-Reliance on Administrative Agent and Other Banks.
Each Bank agrees that it has, independently and without reliance on
Administrative Agent or any other Bank, and based on such documents and
information as it has deemed appropriate, made its own credit analysis of
Borrower and the decision to enter into this Agreement and that it will,
independently and without reliance upon Administrative Agent or any other Bank,
and based on such documents and information as it shall deem appropriate at the
time, continue to make its own analysis and decisions in taking or not taking
action under this Agreement or any other Loan Document. Administrative Agent
shall not be required to keep itself informed as to the performance or
observance by Borrower of this Agreement or any other Loan Document or any other
document referred to or provided for herein or therein or to inspect the
properties or books of Borrower. Except for notices, reports and other documents
and information expressly required to be furnished to the Banks by
Administrative Agent hereunder, Administrative Agent shall not have any duty or
responsibility to provide any Bank with any credit or other information
concerning the affairs, financial condition or business of Borrower (or any
Affiliate of Borrower) which may come into the possession of Administrative
Agent or any of its Affiliates. Administrative Agent shall not be required to
file this Agreement, any other Loan Document or any document or instrument
referred to herein or therein, for record or give notice of this Agreement, any
other Loan Document or any document or instrument referred to herein or therein,
to anyone.

           Section 10.07  Failure of Administrative Agent to Act. Except for
action expressly required of Administrative Agent hereunder, Administrative
Agent shall in all cases be fully justified in failing or refusing to act
hereunder unless it shall have received further assurances (which may include
cash collateral) of the indemnification obligations of the Banks under Section
10.05 in respect of any and all liability and expense which may be incurred by
it by reason of taking or continuing to take any such action. If any indemnity
furnished by the Banks to Administrative Agent for any purpose shall, in the
reasonable opinion of Administrative Agent, be insufficient or become impaired,
Administrative Agent may call for additional indemnity and cease, or not
commence, to do the action indemnified against until such additional indemnity
is furnished.

           Section 10.08  Resignation or Removal of Administrative Agent.
Administrative Agent hereby agrees not to unilaterally resign except in the
event it becomes an Affected Bank and is removed or replaced as a Bank pursuant
to Section 3.07, in which event it shall have the right to resign.
Administrative Agent may be removed at any time with cause by the Required
Banks, provided that Borrower and the other Banks shall be promptly notified
thereof. Upon any such removal, the Required Banks shall have the right to
appoint a successor Administrative Agent which successor Administrative Agent,
so long as it is reasonably acceptable to the Required Banks, shall be that Bank
then having the greatest Loan Commitment. If no successor


                                       51
<PAGE>   57


Administrative Agent shall have been so appointed by the Required Banks and
shall have accepted such appointment within thirty (30) days after the Required
Banks' removal of the retiring Administrative Agent, then the retiring
Administrative Agent may, on behalf of the Banks, appoint a successor
Administrative Agent, which shall be one of the Banks. The Required Banks or the
retiring Administrative Agent, as the case may be, shall upon the appointment of
a successor Administrative Agent promptly so notify Borrower and the other
Banks. Upon the acceptance of any appointment as Administrative Agent hereunder
by a successor Administrative Agent, such successor Administrative Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Administrative Agent, and the retiring Administrative
Agent shall be discharged from its duties and obligations hereunder. After any
retiring Administrative Agent's removal hereunder as Administrative Agent, the
provisions of this Article X shall continue in effect for its benefit in respect
of any actions taken or omitted to be taken by it while it was acting as
Administrative Agent.

           Section 10.09  Amendments Concerning Agency Function. Notwithstanding
anything to the contrary contained herein, Administrative Agent shall not be
bound by any waiver, amendment, supplement or modification hereof or of any
other Loan Document which affects its duties, rights, and/or function hereunder
or thereunder unless it shall have given its prior written consent thereto.

           Section 10.10  Liability of Administrative Agent. Administrative
Agent shall not have any liabilities or responsibilities to Borrower on account
of the failure of any Bank to perform its obligations hereunder or to any Bank
on account of the failure of Borrower to perform its obligations hereunder or
under any other Loan Document.

           Section 10.11  Transfer of Agency Function. Without the consent of
Borrower or any Bank, Administrative Agent may at any time or from time to time
transfer its functions as Administrative Agent hereunder to any of its offices
wherever located in the United States, provided that Administrative Agent shall
promptly notify Borrower and the Banks thereof.

           Section 10.12  Non-Receipt of Funds by Administrative Agent. (a)
Unless Administrative Agent shall have received notice from a Bank or Borrower
(either one as appropriate being the "Payor") prior to the date on which such
Bank is to make payment hereunder to Administrative Agent of the proceeds of a
Loan or Borrower is to make payment to Administrative Agent, as the case may be
(either such payment being a "Required Payment"), which notice shall be
effective upon receipt, that the Payor will not make the Required Payment in
full to Administrative Agent, Administrative Agent may assume that the Required
Payment has been made in full to Administrative Agent on such date, and
Administrative Agent in its sole discretion may, but shall not be obligated to,
in reliance upon such assumption, make the amount thereof available to the
intended recipient on such date. If and to the extent the Payor shall not have
in fact so made the Required Payment in full to Administrative Agent, the
recipient of such payment shall repay to Administrative Agent forthwith on
demand such amount made available to it together with interest thereon, for each
day from the date such amount was so made available by Administrative Agent
until the date Administrative Agent recovers such amount, at the customary rate
set by Administrative Agent for the correction of errors among Banks for three
(3) Banking Days and thereafter at the Base Rate.


                                       52
<PAGE>   58


           (b) If, after Administrative Agent has paid each Bank's share of any
payment received or applied by Administrative Agent in respect of the Loan, that
payment is rescinded or must otherwise be returned or paid over by
Administrative Agent, whether pursuant to any bankruptcy or insolvency law,
sharing of payments clause of any loan agreement or otherwise, such Bank shall,
at Administrative Agent's request, promptly return its share of such payment or
application to Administrative Agent, together with such Bank's proportionate
share of any interest or other amount required to be paid by Administrative
Agent with respect to such payment or application. In addition, if a court of
competent jurisdiction shall adjudge that any amount received and distributed by
Administrative Agent is to be repaid, each Person to whom any such distribution
shall have been made shall either repay to Administrative Agent its share of the
amount so adjudged to be repaid or shall pay over to the same in such manner and
to such Persons as shall be determined by such court.

           Section 10.13  Withholding Taxes. Each Bank represents that it is
entitled to receive any payments to be made to it hereunder without the
withholding of any tax and will furnish to Administrative Agent such forms,
certifications, statements and other documents as Administrative Agent may
request from time to time to evidence such Bank's exemption from the withholding
of any tax imposed by any jurisdiction or to enable Administrative Agent or
Borrower to comply with any applicable Laws or regulations relating thereto.
Without limiting the effect of the foregoing, if any Bank is not created or
organized under the laws of the United States of America or any state thereof,
such Bank will furnish to Administrative Agent a United States Internal Revenue
Service Form 4224 in respect of all payments to be made to such Bank by Borrower
or Administrative Agent under this Agreement or any other Loan Document or a
United States Internal Revenue Service Form 1001 establishing such Bank's
complete exemption from United States withholding tax in respect of payments to
be made to such Bank by Borrower or Administrative Agent under this Agreement or
any other Loan Document, or such other forms, certifications, statements or
documents, duly executed and completed by such Bank as evidence of such Bank's
exemption from the withholding of U.S. tax with respect thereto. Administrative
Agent shall not be obligated to make any payments hereunder to such Bank in
respect of any Loan or participation or such Bank's Loan Commitment or
obligation to purchase participations until such Bank shall have furnished to
Administrative Agent the requested form, certification, statement or document.

           Section 10.14  Minimum Commitment by Co-Agents. Subsequent to the
Closing Date and provided there exists no Event of Default, Fleet agrees to
maintain a Loan Commitment in an amount no less than $25,000,000. Fleet further
agrees to hold and not to participate or assign any of such amount other than an
assignment to a Federal Reserve Bank or to its Parent or a majority-owned
subsidiary. In addition, each of Morgan and UBS agrees that, in the event it
sells its individual Loan Commitment down to zero, it may be removed as a
Co-Agent and either Syndication Agent or Documentation Agent, as the case may
be, by the Required Banks.

           Section 10.15  Pro Rata Treatment. Except to the extent otherwise
provided, (1) each advance of proceeds of the Ratable Loans shall be made by the
Banks; (2) each reduction of the amount of the Total Loan Commitment under
Section 2.10 shall be applied to the Loan Commitments of the Banks; and (3) each
payment of the fee accruing under paragraph (b) of Section 2.07 and clause (1)
of Section 2.16(f) shall be made for the account of the Banks, ratably according
to the amounts of their respective Loan Commitments.

           Section 10.16  Sharing of Payments Among Banks. If a Bank shall
obtain payment of any principal of or interest on any Loan made by it through
the exercise of any right of setoff, banker's lien, counterclaim, or by any
other means (including direct payment), and such


                                       53
<PAGE>   59


payment results in such Bank receiving a greater payment than it would have been
entitled to had such payment been paid directly to Administrative Agent for
disbursement to the Banks, then such Bank shall promptly purchase for cash from
the other Banks participations in the Loans made by the other Banks in such
amounts, and make such other adjustments from time to time as shall be equitable
to the end that all the Banks shall share ratably the benefit of such payment.
To such end the Banks shall make appropriate adjustments among themselves (by
the resale of participations sold or otherwise) if such payment is rescinded or
must otherwise be restored. Borrower agrees that any Bank so purchasing a
participation in the Loans made by other Banks may exercise all rights of
setoff, banker's lien, counterclaim or similar rights with respect to such
participation. Nothing contained herein shall require any Bank to exercise any
such right or shall affect the right of any Bank to exercise, and retain the
benefits of exercising, any such right with respect to any other indebtedness of
Borrower.

           Section 10.17  Possession of Documents. Each Bank shall keep
possession of its own Ratable Loan Note and the Swing Lender shall keep
possession of its Swing Loan Note. Administrative Agent shall hold all the other
Loan Documents and related documents in its possession and maintain separate
records and accounts with respect thereto, and shall permit the Banks and their
representatives access at all reasonable times to inspect such Loan Documents,
related documents, records and accounts.

                                   ARTICLE XI

                              NATURE OF OBLIGATIONS

           Section 11.01  Absolute and Unconditional Obligations. Borrower
acknowledges and agrees that its obligations and liabilities under this
Agreement and under the other Loan Documents shall be absolute and unconditional
irrespective of (1) any lack of validity or enforceability of any of the
Obligations, any Loan Documents, or any agreement or instrument relating
thereto; (2) any change in the time, manner or place of payment of, or in any
other term in respect of, all or any of the Obligations, or any other amendment
or waiver of or consent to any departure from any Loan Documents or any other
documents or instruments executed in connection with or related to the
Obligations; (3) any exchange or release of any collateral, if any, or of any
other Person from all or any of the Obligations; or (4) any other circumstances
which might otherwise constitute a defense available to, or a discharge of,
Borrower or any other Person in respect of the Obligations.

           The obligations and liabilities of Borrower under this Agreement and
other Loan Documents shall not be conditioned or contingent upon the pursuit by
any Bank or any other Person at any time of any right or remedy against Borrower
or any other Person which may be or become liable in respect of all or any part
of the Obligations or against any collateral or security or guarantee therefor
or right of setoff with respect thereto.

           Section 11.02  Non-Recourse to Borrower's Principals. Notwithstanding
anything to the contrary contained herein, in any of the other Loan Documents,
or in any other instruments, certificates, documents or agreements executed in
connection with the Loans (all of the foregoing, for purposes of this Section,
hereinafter referred to, individually and collectively, as the "Relevant
Documents"), no recourse under or upon any Obligation, representation, warranty,
promise or other matter whatsoever shall be had against any of Borrower's
Principals and each Bank expressly waives and releases, on behalf of itself and
its successors and assigns,


                                       54
<PAGE>   60


all right to assert any liability whatsoever under or with respect to the
Relevant Documents against, or to satisfy any claim or obligation arising
thereunder against, any of Borrower's Principals or out of any assets of
Borrower's Principals, provided, however, that nothing in this Section shall be
deemed to (1) release Borrower from any personal liability pursuant to, or from
any of its respective obligations under, the Relevant Documents, or from
personal liability for its fraudulent actions or fraudulent omissions; (2)
release any of Borrower's Principals from personal liability for its or his own
fraudulent actions or fraudulent omissions; (3) constitute a waiver of any
obligation evidenced or secured by, or contained in, the Relevant Documents or
affect in any way the validity or enforceability of the Relevant Documents; or
(4) limit the right of Administrative Agent and/or the Banks to proceed against
or realize upon any collateral hereafter given for the Loans or any and all of
the assets of Borrower (notwithstanding the fact that any or all of Borrower's
Principals have an ownership interest in Borrower and, thereby, an interest in
the assets of Borrower) or to name Borrower (or, to the extent that the same are
required by applicable law or are determined by a court to be necessary parties
in connection with an action or suit against Borrower or any collateral
hereafter given for the Loans, any of Borrower's Principals) as a party
defendant in, and to enforce against any collateral hereafter given for the
Loans and/or assets of Borrower any judgment obtained by Administrative Agent
and/or the Banks with respect to, any action or suit under the Relevant
Documents so long as no judgment shall be taken (except to the extent taking a
judgment is required by applicable law or determined by a court to be necessary
to preserve Administrative Agent's and/or Banks' rights against any collateral
hereafter given for the Loans or Borrower, but not otherwise) or shall be
enforced against Borrower's Principals or their assets.

                                  ARTICLE XII

                                  MISCELLANEOUS

           Section 12.01  Binding Effect of Request for Advance. Borrower agrees
that, by its acceptance of any advance of proceeds of the Loans under this
Agreement, it shall be bound in all respects by the request for advance
submitted on its behalf in connection therewith with the same force and effect
as if Borrower had itself executed and submitted the request for advance and
whether or not the request for advance is executed and/or submitted by an
authorized person.

           Section 12.02  Amendments and Waivers. No amendment or any material
waiver of any provision of this Agreement or any other Loan Document nor consent
to any material departure by Borrower therefrom, shall in any event be effective
unless the same shall be in writing and signed by the Required Banks and, solely
for purposes of its acknowledgment thereof, Administrative Agent, and then such
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given, provided, however, that no amendment, waiver
or consent shall, unless in writing and signed by all the Banks do any of the
following: (1) reduce the principal of, or interest on, the Notes or any fees
due hereunder or any other amount due hereunder or under any Loan Document; (2)
postpone any date fixed for any payment of principal of, or interest on, the
Notes or any fees due hereunder or under any Loan Document; (3) change the
definition of Required Banks; (4) amend this Section or any other provision
requiring the consent of all the Banks; or (5) waive any default under paragraph
(5) of Section 9.01. Any advance of proceeds of the Loans made prior to or
without the fulfillment by Borrower of all of the conditions precedent thereto,
whether or not known to Administrative


                                       55
<PAGE>   61


Agent and the Banks, shall not constitute a waiver of the requirement that all
conditions, including the non-performed conditions, shall be required with
respect to all future advances. No failure on the part of Administrative Agent
or any Bank to exercise, and no delay in exercising, any right hereunder shall
operate as a waiver thereof or preclude any other or further exercise thereof or
the exercise of any other right. The remedies herein provided are cumulative and
not exclusive of any remedies provided by law. 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 thing as
to which such determination, approval, consent or disapproval is requested and
(iii) 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) Banking Days (or five (5) Banking Days with respect to any
decision to accelerate or stop acceleration of the Loan) after receipt of the
request therefor by 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 or consented to such recommendation
or determination.

           Section 12.03  Usury. Anything herein to the contrary
notwithstanding, the obligations of Borrower under this Agreement and the Notes
shall be subject to the limitation that payments of interest shall not be
required to the extent that receipt thereof would be contrary to provisions of
law applicable to a Bank limiting rates of interest which may be charged or
collected by such Bank.

           Section 12.04  Expenses; Indemnification. Borrower agrees to
reimburse Co-Agents and Administrative Agent on demand for all costs, expenses,
and charges (including, without limitation, all reasonable fees and charges of
engineers, appraisers and legal counsel) incurred by any of them in connection
with the Loans and to reimburse each of the Banks for reasonable legal costs,
expenses and charges incurred by each of the Banks in connection with the
performance or enforcement of this Agreement, the Notes, or any other Loan
Documents; provided, however, that Borrower is not responsible for costs,
expenses and charges incurred by the Bank Parties in connection with the
administration or syndication of the Loans (other than the fees required by the
Supplemental Fee Letter). Borrower agrees to indemnify Administrative Agent and
each Bank and their respective directors, officers, employees and agents from,
and hold each of them harmless against, any and all losses, liabilities, claims,
damages or expenses incurred by any of them arising out of or by reason of (x)
any claims by brokers due to acts or omissions by Borrower, or (y) any
investigation or litigation or other proceedings (including any threatened
investigation or litigation or other proceedings) relating to any actual or
proposed use by Borrower of the proceeds of the Loans, including without
limitation, the reasonable fees and disbursements of counsel incurred in
connection with any such investigation or litigation or other proceedings (but
excluding any such losses, liabilities, claims, damages or expenses incurred by
reason of the gross negligence or willful misconduct of the Person to be
indemnified).

           The obligations of Borrower under this Section shall survive the
repayment of all amounts due under or in connection with any of the Loan
Documents and the termination of the Loans.

           Section 12.05  Assignment; Participation. This Agreement shall be
binding upon, and shall inure to the benefit of, Borrower, Administrative Agent,
the Banks and their respective successors and permitted assigns. Borrower may
not assign or transfer its rights or obligations hereunder.

           Any Bank may at any time grant to one or more banks or other
institutions (each a "Participant") participating interests in its Loan (the
"Participations"). In the event of any such grant by a Bank of a Participation
to a Participant, whether or not Borrower or Administrative Agent was given
notice, such Bank shall remain responsible for the performance of its
obligations hereunder, and Borrower and Administrative Agent shall continue to
deal solely and directly with such Bank in connection with such Bank's rights
and obligations hereunder. 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 Borrower hereunder and
under any other Loan Document including, without limitation, the right to
approve any amendment, modification or waiver of any provision of this Agreement
or any other Loan Document; 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 (1) through (5) of Section 12.02 without
the consent of the Participant.

           Subject to the provisions of Section 10.14, any Bank may at any time
assign to any bank or other institution with the acknowledgment of
Administrative Agent and the consent of Co-Agents and, provided there exists no
Event of Default, Borrower, which consents shall not be unreasonably withheld or
delayed (such assignee, a "Consented Assignee"), or to one or more banks or
other institutions which are majority owned subsidiaries of a Bank or to the
Parent of a Bank (each Consented Assignee or subsidiary bank or institution, an
"Assignee") all, or a proportionate part of all, of its rights and obligations
under this Agreement and its Note, and such Assignee shall assume rights and
obligations, pursuant to an Assignment and Assumption Agreement executed by such
Assignee and the assigning Bank, provided that, in each case, after giving
effect to such assignment the Assignee's Loan Commitment, and, in the case of a
partial assignment, the assigning Bank's Loan Commitment, each will be equal to
or greater than $10,000,000, provided, further, however, that the assigning Bank
shall not be required to maintain a Loan Commitment in the minimum amount
aforesaid in the event it assigns all of its rights and obligations under this
Agreement and its Note. Notwithstanding the provisions of the immediately
preceding sentence, the consents of Co-Agents and Borrower shall not be required
in the case of assignments by any Bank provided that the Assignee thereunder (or
a guarantor of such Assignee's obligations under this Agreement) has a credit
rating of AA (or its equivalent) or better from a nationally recognized rating
agency, and provided, further, however, that assignments by the Co-Agents shall
remain subject to the provisions of Section 10.14. Upon (i) execution and
delivery of such instrument, (ii) payment by such Assignee to the Bank of an
amount equal to the purchase price agreed between the Bank and such Assignee and
(iii) payment by such Assignee to Administrative Agent of a fee, for
Administrative Agent's own account, in the amount of $2,500, such Assignee shall
be a Bank Party to this Agreement and shall have all the rights and obligations
of a Bank as set forth in such Assignment and Assumption Agreement, and the
assigning Bank shall be released from its obligations hereunder to a
corresponding extent, and no further consent or action by any party shall be
required. Upon the consummation of any assignment pursuant to this paragraph,
substitute Ratable Loan Notes (and, if applicable, Swing Loan Notes) shall be
issued to the assigning Bank and Assignee by


                                       57
<PAGE>   63


Borrower, in exchange for the return of the original Ratable Loan Note (and, if
applicable, Swing Loan Note). The obligations evidenced by such substitute notes
shall constitute "Obligations" for all purposes of this Agreement and the other
Loan Documents. In connection with Borrower's execution of substitute notes as
aforesaid, Borrower shall deliver to Administrative Agent evidence, satisfactory
to Administrative Agent, of all requisite corporate action to authorize
Borrower's execution and delivery of the substitute notes and any related
documents. If the Assignee is not incorporated under the laws of the United
States of America or a state thereof, it shall, prior to the first date on which
interest or fees are payable hereunder for its account, deliver to Borrower and
Administrative Agent certification as to exemption from deduction or withholding
of any United States federal income taxes in accordance with Section 10.13. Each
Assignee shall be deemed to have made the representations contained in, and
shall be bound by the provisions of, Section 10.13.

           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.

           Borrower recognizes that in connection with a Bank's selling of
Participations or making of assignments, any or all documentation, financial
statements, appraisals and other data, or copies thereof, relevant to Borrower
or the Loans may be exhibited to and retained by any such Participant or
assignee or prospective Participant or assignee. In connection with a Bank's
delivery of any financial statements and appraisals to any such Participant or
assignee or prospective Participant or assignee, such Bank shall also indicate
that the same are delivered on a confidential basis. Borrower agrees to provide
all assistance reasonably requested by a Bank to enable such Bank to sell
Participations or make assignments of its Loan as permitted by this Section.
Each Bank agrees to provide Borrower with notice of all Participations sold by
such Bank to other than its Affiliates.

           Section 12.06  Documentation Satisfactory. All documentation required
from or to be submitted on behalf of Borrower in connection with this Agreement
and the documents relating hereto shall be subject to the prior approval of, and
be satisfactory in form and substance to, Administrative Agent, its counsel and,
where specifically provided herein, the Banks. In addition, the persons or
parties responsible for the execution and delivery of, and signatories to, all
of such documentation, shall be acceptable to, and subject to the approval of,
Administrative Agent and its counsel and the Banks.

           Section 12.07  Notices. Unless the party to be notified otherwise
notifies the other party in writing as provided in this Section, and except as
otherwise provided in this Agreement, notices shall be given to Administrative
Agent by telephone, confirmed by writing, and to the Banks and to Borrower by
ordinary mail or overnight courier, receipt confirmed, addressed to such party
at its address on the signature page of this Agreement. Notices shall be
effective (1) if by telephone, at the time of such telephone conversation, (2)
if given by mail, three (3) days after mailing; and (3) if given by overnight
courier, upon receipt.

           Section 12.08  Setoff. Borrower agrees that, in addition to (and
without limitation of) any right of setoff, bankers' lien or counterclaim a Bank
may otherwise have, each Bank shall be entitled, at its option, to offset
balances (general or special, time or demand, provisional or


                                       58
<PAGE>   64


final) held by it for the account of Borrower at any of such Bank's offices, in
Dollars or in any other currency, against any amount payable by Borrower to such
Bank under this Agreement or such Bank's Note, or any other Loan Document which
is not paid when due (regardless of whether such balances are then due to
Borrower), in which case it shall promptly notify Borrower and Administrative
Agent thereof; provided that such Bank's failure to give such notice shall not
affect the validity thereof. Payments by Borrower hereunder or under the other
Loan Documents shall be made without setoff or counterclaim.

           Section 12.09  Table of Contents; Headings. Any table of contents and
the headings and captions hereunder are for convenience only and shall not
affect the interpretation or construction of this Agreement.

           Section 12.10  Severability. The provisions of this Agreement are
intended to be severable. If for any reason any provision of this Agreement
shall be held invalid or unenforceable in whole or in part in any jurisdiction,
such provision shall, as to such jurisdiction, be ineffective to the extent of
such invalidity or unenforceability without in any manner affecting the validity
or enforceability thereof in any other jurisdiction or the remaining provisions
hereof in any jurisdiction.

           Section 12.11  Counterparts. This Agreement may be executed in any
number of counterparts, all of which taken together shall constitute one and the
same instrument, and any party hereto may execute this Agreement by signing any
such counterpart.

           Section 12.12  Integration. The Loan Documents and Supplemental Fee
Letter set forth the entire agreement among the parties hereto relating to the
transactions contemplated thereby and supersede any prior oral or written
statements or agreements with respect to such transactions.

           Section 12.13  Governing Law. This Agreement shall be governed by,
and interpreted and construed in accordance with, the laws of the State of New
York.

           Section 12.14  Waivers. In connection with the obligations and
liabilities as aforesaid, Borrower hereby waives (1) promptness and diligence;
(2) notice of any actions taken by any Bank Party under this Agreement, any
other Loan Document or any other agreement or instrument relating thereto except
to the extent otherwise provided herein; (3) all other notices, demands and
protests, and all other formalities of every kind in connection with the
enforcement of the Obligations, the omission of or delay in which, but for the
provisions of this Section, might constitute grounds for relieving Borrower of
its obligations hereunder; (4) any requirement that any Bank Party protect,
secure, perfect or insure any Lien on any collateral or exhaust any right or
take any action against Borrower or any other Person or any collateral; (5) any
right or claim of right to cause a marshalling of the assets of Borrower; and
(6) all rights of subrogation or contribution, whether arising by contract or
operation of law (including, without limitation, any such right arising under
the Federal Bankruptcy Code) or otherwise by reason of payment by Borrower,
either jointly or severally, pursuant to this Agreement or other Loan Documents.

           Section 12.15  Jurisdiction; Immunities. Borrower, Administrative
Agent and each Bank hereby irrevocably submit to the jurisdiction of any New
York State or United States


                                       59
<PAGE>   65


Federal court sitting in New York City over any action or proceeding arising out
of or relating to this Agreement, the Notes or any other Loan Document.
Borrower, Administrative Agent, and each Bank irrevocably agree that all claims
in respect of such action or proceeding may be heard and determined in such New
York State or United States Federal court. Borrower, Administrative Agent, and
each Bank irrevocably consent to the service of any and all process in any such
action or proceeding by the mailing of copies of such process to Borrower,
Administrative Agent or each Bank, as the case may be, at the addresses
specified herein. Borrower, Administrative Agent and each Bank agree that a
final judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law. Borrower, Administrative Agent and each Bank further waive any
objection to venue in the State of New York and any objection to an action or
proceeding in the State of New York on the basis of forum non conveniens.
Borrower, Administrative Agent and each Bank agree that any action or proceeding
brought against Borrower, Administrative Agent or any Bank, as the case may be,
shall be brought only in a New York State court sitting in New York City or a
United States Federal court sitting in New York City, to the extent permitted or
not expressly prohibited by applicable law.

           Nothing in this Section shall affect the right of Borrower,
Administrative Agent or any Bank to serve legal process in any other manner
permitted by law.

           To the extent that Borrower, Administrative Agent or any Bank have or
hereafter may acquire any immunity from jurisdiction of any court or from any
legal process (whether from service or notice, attachment prior to judgment,
attachment in aid of execution, execution or otherwise) with respect to itself
or its property, Borrower, Administrative Agent and each Bank hereby irrevocably
waive such immunity in respect of its obligations under this Agreement, the
Notes and any other Loan Document.

           BORROWER, ADMINISTRATIVE AGENT AND EACH BANK WAIVE ANY RIGHT EACH
SUCH PARTY MAY HAVE TO JURY TRIAL IN CONNECTION WITH ANY SUIT, ACTION OR
PROCEEDING BROUGHT WITH RESPECT TO THIS AGREEMENT, THE NOTES OR THE LOANS.

           Section 12.16  Designated Lender. Any Bank (other than a Bank who is
such solely because it is a Designated Lender) (each, a "Designating Lender")
may at any time designate one (1) Designated Lender to fund Bid Rate Loans on
behalf of such Designating Lender subject to the terms of this Section and the
provisions in Section 12.05 shall not apply to such designation. No Bank may
designate more than one (1) Designated Lender. The parties to each such
designation shall execute and deliver to Administrative Agent for its acceptance
a Designation Agreement. Upon such receipt of an appropriately completed
Designation Agreement executed by a Designating Lender and a designee
representing that it is a Designated Lender, Administrative Agent will accept
such Designation Agreement and give prompt notice thereto to Borrower,
whereupon, (i) from and after the "Effective Date" specified in the Designation
Agreement, the Designated Lender shall become a party to this Agreement with a
right to make Bid Rate Loans on behalf of its Designating Lender pursuant to
Section 2.02 after Borrower has accepted the Bid Rate Quote of the Designating
Lender and (ii) 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


                                       60
<PAGE>   66


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 Borrower, Administrative Agent and the Banks for each and every of the
obligations of the Designating Lender and its related Designated Lender with
respect to this Agreement, including, without limitation, any indemnification
obligations under Section 10.05. Each Designating Lender shall serve as the
administrative agent of its 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 and consents under or relating to this
Agreement and the other Loan Documents. Any such notice, communication, vote,
approval, waiver or consent 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, but shall be binding on the Designated
Lender to the same extent as if actually signed by the Designated Lender.
Borrower, Administrative Agent and the Banks may rely thereon without any
requirement that the Designated Lender sign or acknowledge the same. No
Designated Lender may assign or transfer all or any portion of its interest
hereunder or under any other Loan Document, other than assignments to the
Designating Lender which originally designated such Designated Lender.

           Section 12.17  No Bankruptcy Proceedings. Each of Borrower, the Banks
and Administrative Agent hereby agrees that it will not institute against any
Designated Lender or join any other Person in instituting against any Designated
Lender any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceeding under any federal or state bankruptcy or similar law, for one (1)
year and one (1) day after the payment in full of the latest maturing commercial
paper note issued by such Designated Lender.

           Section 12.18  Year 2000. Borrower represents, warrants and covenants
that Borrower has taken and shall take all action reasonably necessary to assure
that its data processing and information technology systems are capable of
effectively processing data and information, including dates on and after
January 1, 2000, and shall not cease to perform, or provide, or cause any
software and/or system which is material to its operations or any interface
therewith to provide, invalid or incorrect results as a result of date
functionality and/or data, or otherwise experience any material degradation of
performance or functionality arising from, relating to or including date
functionality and/or data which represents or references different centuries or
more than one century or leap years, and that all such systems shall be
reasonably effective and accurate in managing and manipulating data derived
from, involving or relating in any way to dates (including single century
formulas and multi-century or leap year formulas), and will not cause a material
abnormally ending scenario within such systems or in any software and/or system
with which such systems interface, or generate materially incorrect values or
invalid results involving such dates. At the request of Administrative Agent,
Borrower shall provide Administrative Agent with reasonably acceptable assurance
of Borrower's year 2000 capability.

                              Designation Agreement
                              ---------------------

            Reference is made to that certain Revolving Loan Agreement dated as
of ____________, 1998 (as amended, supplemented or otherwise modified from time
to time, the "Loan Agreement") among Avalon Bay Communities, Inc., a Maryland
corporation, the banks parties thereto, and Fleet National Bank, as
administrative agent for said banks. Terms defined in the Loan Agreement not
otherwise defined herein are used herein with the same meaning.

            [BANK] ("Designor") and ____________________, a ____________________
("Designee") agree as follows:

            1.    Designor hereby designates Designee, and Designee hereby
accepts such designation, to have a right to make Bid Rate Loans pursuant to
Section 2.02 of the Loan Agreement. Any assignment by Designor to Designee of
its rights to make a Bid Rate Loan pursuant to such Section shall be effective
at the time of the funding of such Bid Rate Loan and not before such time.

            2.    Except as set forth in Section 6 below, Designor makes no
representation or warranty and assumes no responsibility pursuant to this
Designation Agreement with respect to (a) any statements, warranties or
representations made in or in connection with any Loan Document or the
execution, legality, validity, enforceability, genuineness, sufficiency or value
of any Loan Document or any other instrument and document furnished pursuant
thereto and (b) the financial condition of Borrower or the performance or
observance by Borrower of any of its obligations under any Loan Document or any
other instrument or document furnished pursuant thereto.

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

            4.    Designee hereby appoints Designor as Designee's agent and
attorney-in-fact, and grants to Designor an irrevocable power of attorney, to
receive payments made for the benefit of Designee under the Loan Agreement, to
deliver and receive all communications and notices under the Loan Agreement and
other Loan Documents and to exercise on Designee's behalf all rights to vote and
to grant and make approvals, waivers, consents or amendments to or under the
Loan Agreement or other Loan Documents. Any document executed by Designor on

                                      F-1

<PAGE>   97

Designee's behalf in connection with the Loan Agreement or other Loan Documents
shall be binding on Designee. Borrower, Administrative Agent and each of the
Banks may rely on and are beneficiaries of this Designation Agreement.

            5.    Following the execution of this Designation Agreement by
Designor and Designee, it will be delivered to Administrative Agent for
acceptance by Administrative Agent. The effective date for this Designation
Agreement (the "Effective Date") shall be the date of acceptance hereof by
Administrative Agent.

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

            7.    As of the Effective Date, Designee shall be a party to the
Loan Agreement with a right to make Bid Rate Loans as a Bank pursuant to Section
2.02 of the Loan Agreement and the rights and obligations of a Bank related
thereto; provided, however, that Designee shall not be required to make payments
with respect to such obligations except to the extent of excess cash flow of
such Designee which is not otherwise required to repay obligations of such
Designated Lender which are then due and payable. Notwithstanding the foregoing,
Designor, as administrative agent for Designee, shall be and remain obligated to
Borrower, Administrative Agent and the Banks for each and every of the
obligations of Designee and its Designor with respect to the Loan Agreement,
including, without limitation, any indemnification obligations under Section
10.05 of the Loan Agreement.

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

            9.    This Designation Agreement may be executed in any number of
counterparts and by different parties hereto in separate counterparts, each of
which when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

            IN WITNESS WHEREOF, Designor and Designee have executed and
delivered this Designation Agreement as of the date first set forth above.
