set forth in this Agreement, each of the Banks severally agrees to lend to the
Borrowers, and the Borrowers may borrow (and repay and reborrow) from time to
time between the Closing Date and the Maturity Date upon notice by the
Borrowers to the Agent given in accordance with Section 2.6, such sums as are
requested by the Borrowers for the purposes set forth in Section 7.11 up to the
lesser of (a) a maximum aggregate principal amount outstanding (after giving
effect to all amounts requested) at any one time equal to such Bank's
Commitment and (b) such Bank's Commitment Percentage of the Borrowing Base and
the Collateral Borrowing Base (whichever is less), provided, that, in all
events no Default or Event of Default shall have occurred and be continuing;
and provided, further, that the outstanding principal amount of the Loans
(after giving effect to all amounts requested) shall not at any time exceed the
Total Commitment. The Loans (other than Swing Loans) shall be made pro rata in
accordance with each Bank's Commitment Percentage. Each request for a Loan
hereunder shall constitute a representation and warranty by the Borrowers that
all of the conditions set forth in Section 10 and Section 11, in the case of
the initial Loan, and Section 11, in the case of all other Loans, have been
satisfied on the date of such request. No Bank shall have any obligation to
make Loans to the Borrowers in the maximum aggregate principal amount
outstanding of more than the principal face amount of its Note.

         Section 2.2. Facility Fee. The Borrowers agree to pay to the Agent for
the account of the Banks in accordance with their respective Commitment
Percentages a facility fee calculated at the rate per annum as set forth below

thereof commencing on the date hereof and ending on the Maturity Date. The
facility fee shall be calculated based on the ratio (expressed as a percentage)
of (a) the average daily amount of the outstanding principal amount of the
Loans during such quarter to (b) the Total Commitment as follows:

<TABLE>
<CAPTION>
                  Ratio of Outstanding Principal
                   Balance to Total Commitment                       Rate
                  ------------------------------                     -----
                  <S>                                                <C>
                          33.33% or less                             0.25%
                   Greater than 33.33% but not
                         more than 66.67%                            0.20%
                       Greater than 66.67%                           0.15%
</TABLE>

The facility fee shall be payable quarterly in arrears on the first day of each
calendar quarter for the immediately preceding calendar quarter or portion
thereof, and on any earlier date on which the Commitments shall be reduced or
shall terminate as provided in Section 2.3, with a final payment on the
Maturity Date.

         Section 2.3. Reduction and Termination of Commitment. The Borrowers
shall have the right at any time and from time to time upon five Business Days'
prior written notice to the Agent to reduce by $5,000,000 or an integral
multiple of $1,000,000 in excess thereof (provided that in no event shall the
Total Commitment be reduced to an amount less than $50,000,000.00) or to
terminate entirely the unborrowed portion of the Commitments, whereupon the
Commitments of the Banks shall be reduced pro rata in accordance with their
respective Commitment Percentages of the amount specified in such notice or, as
the case may be, terminated, any such termination or reduction to be without
penalty (unless such termination or reduction requires repayment of a LIBOR
Rate Loan); provided, however, that no such termination or reduction shall be
permitted if, after giving effect thereto, the Outstanding Loans would exceed
the Commitments of the Banks as so terminated or reduced. In the event that as
a result of the reduction or termination of the Commitments, the Commitment of
the Swing Loan Bank shall be reduced to an amount less than the Swing Loan
Commitment, the Swing Loan Commitment shall automatically and without further
action of the parties be reduced to an equal amount. Promptly after receiving
any notice of the Borrowers delivered pursuant to this Section 2.3, the Agent
will notify the Banks of the substance thereof. Upon the effective date of any
such reduction or termination, the Borrowers shall pay to the Agent for the
respective accounts of the Banks the full amount of any facility fee under
Section 2.2 then accrued on the amount of the reduction. No reduction or
termination of the Commitment or Swing Loan Commitment may be reinstated.

         Section 2.4. Notes. The Loans (other than Swing Loans) shall be
evidenced by separate promissory notes of the Borrowers in substantially the
form of Exhibit F hereto (collectively, the "Revolving Credit Notes"), dated
the date of this Agreement and completed with appropriate insertions. One
Revolving Credit Note shall be payable to the order of each Bank in the
principal face amount equal to such Bank's Commitment and shall be payable as
set forth below. The Borrowers irrevocably authorize each Bank to make or cause
to be made, at or about the time of the Drawdown Date of any Loan (other than
Swing Loans) or at the time of receipt of any payment of principal thereof, an
appropriate notation on such Bank's Record reflecting the making of such Loan
or (as the case may be) the receipt of such payment. The outstanding amount of
the Loans (other than Swing Loans) set forth on such Bank's Record shall be
prima facie evidence of the principal amount thereof owing and unpaid to such
Bank, but the failure to record, or any error in so recording, any such amount
on such Bank's Record shall not limit or otherwise affect the obligations of
the Borrowers hereunder or under any Revolving Credit Note to make payments of
principal of or interest on any Revolving Credit Note when due. By delivery of
the Revolving Credit Notes, there shall not be deemed to have occurred, and
there has not otherwise occurred, any payment, satisfaction or novation of the
indebtedness evidenced by the "Notes" as defined in the Original Credit
Agreement, which indebtedness is instead allocated among the Banks as of the
date hereof and evidenced by the Revolving Credit Notes in accordance with
their respective Commitment Percentages.

         Section 2.4A Swing Loan Commitments.

                      (a) Subject to the terms and conditions set forth in this
Agreement, and if necessary to meet the Borrowers' funding deadlines, Swing
Loan Bank agrees to lend to the Borrowers (the "Swing Loans"), and the
Borrowers may borrow (and repay and reborrow) from


                                      -17-

<PAGE>   19

time to time between the Closing Date and the date which is seven (7) Business
Days prior to the Maturity Date upon notice by the Borrowers to the Swing Loan
Bank given in accordance with this Section 2.4A, such sums as are requested by
the Borrowers for the purposes set forth in Section 7.11 in an aggregate
principal amount at any one time outstanding not exceeding the Swing Loan
Commitment; provided that at no time shall the aggregate principal balance of
Swing Loans then outstanding, when added to the Swing Loan Bank's Commitment
Percentage of all other Outstanding Loans (after giving effect to all amounts
requested), exceed the lesser of (i) such Bank's Commitment and (ii) such
Bank's Commitment Percentage of the Borrowing Base and the Collateral Borrowing
Base (whichever is less), provided, further, that in all events no Default or
Event of Default shall have occurred and be continuing; and provided, further,
that the outstanding principal amount of the Loans (after giving effect to all
amounts requested) shall not at any time exceed the Total Commitment. Swing
Loans shall constitute "Loans" for all purposes hereunder, but shall not be
considered the utilization of a Bank's Commitment. The funding of a Swing Loan
hereunder shall constitute a representation and warranty by the Borrowers that
all of the conditions set forth in Section 10 and Section 11, in the case of
the initial Swing Loan, and Section 11, in the case of all other Swing Loans,
have been satisfied on the date of such funding.

                      (b) The Swing Loans shall be evidenced by a separate
promissory note of the Borrowers in substantially the form of Exhibit G hereto
(the "Swing Loan Note"), dated the date of this Agreement and completed with
appropriate insertions. The Swing Loan Note shall be payable to the order of
the Swing Loan Bank in the principal face amount equal to the Swing Loan
Commitment and shall be payable as set forth below. The Borrowers irrevocably
authorize the Swing Loan Bank to make or cause to be made, at or about the time
of the Drawdown Date of any Swing Loan or at the time of receipt of any payment
of principal thereof, an appropriate notation on the Swing Loan Bank's Record
reflecting the making of such Swing Loan or (as the case may be) the receipt of
such payment. The outstanding amount of the Swing Loans set forth on the Swing
Loan Bank's Record shall be prima facia evidence of the principal amount
thereof owing and unpaid to the Swing Loan Bank, but the failure to record, or
any error in so recording, any such amount on the Swing Loan Bank's Record
shall not limit or otherwise affect the obligations of the Borrowers hereunder
or under the Swing Loan Note to make payments of principal of or interest on
any Swing Loan Note when due.

                      (c) Each borrowing of Swing Loan shall be subject to the
limits for Base Rate Loans and LIBOR Rate Loans set forth in Section 2.6.
Borrowers shall request a Swing Loan by delivering to the Swing Loan Bank a
Loan Request no later than 9:00 a.m. (Boston time) on the requested Drawdown
Date specifying the amount of the requested Swing Loan. The Loan Request shall
also contain the statements and certifications required by Section 2.6(i) and
(ii). Each such Loan Request shall be irrevocable and binding on the Borrowers
and shall obligate the Borrowers to accept such Swing Loan on the Drawdown
Date. Notwithstanding anything herein to the contrary, a Swing Loan shall
either be a Base Rate Loan or a LIBOR Rate Loan having an Interest Period of
one month, and in the event that the Borrowers fail to specify whether they
have selected a Base Rate Loan or a LIBOR Rate Loan, the Borrowers shall be
deemed conclusively to have selected a LIBOR Rate Loan with an Interest Period
of one month. Notwithstanding the foregoing, upon the date that the Banks shall
be required to fund the Loans 


                                      -18-

<PAGE>   20

pursuant to Section 2.4A(d) to refund such Swing Loan, the interest rate shall
be reset to a LIBOR Rate Loan with an Interest Period as specified in the Loan
Request given by the Borrowers to the Agent in connection with such Swing Loan,
or if no Interest Period is specified, then as a Base Rate Loan. The proceeds
of the Swing Loan will be made available by the Swing Loan Bank to the
Borrowers at the Agent's Head Office by crediting the account of the Borrowers
at such office with such proceeds.

                      (d) The Swing Loan Bank shall within three (3) Business
Days after the Drawdown Date with respect to such Swing Loan, request each
Bank, including the Swing Loan Bank, to make a Loan pursuant to Section 2.1 in
an amount equal to such Bank's Commitment Percentage of the amount of the Swing
Loan outstanding on the date such notice is given. Borrowers hereby irrevocably
authorize and direct the Swing Loan Bank to so act on its behalf, and agree
that any amount advanced to the Agent for the benefit of the Swing Loan Bank
pursuant to this Section 2.4A(d) shall be considered a Loan pursuant to Section
2.1. Unless any of the events described in paragraph (h), (i) or (j) of Section
12.1 shall have occurred (in which event the procedures of Section 2.4A(e)
shall apply), each Bank shall make the proceeds of its Loan available to the
Swing Loan Bank for the account of the Swing Loan Bank at the Agent's Head
Office prior to 12:00 noon (Boston time) in funds immediately available no
later than the third (3rd) Business Day after the date such notice is given
just as if the Banks were funding directly to the Borrowers, so that thereafter
such Obligations shall be evidenced by the Revolving Credit Notes. The proceeds
of such Loan shall be immediately applied to repay the Swing Loans.

                      (e) If prior to the making of a Loan pursuant to Section
2.4A(d) by all of the Banks, one of the events described in Section 12.1(h),
(i) or (j) shall have occurred, each Bank will, on the date such Loan pursuant
to Section 2.4A(d) was to have been made, purchase an undivided participating
interest in the Swing Loan in an amount equal to its Commitment Percentage of
such Swing Loan. Each Bank will immediately transfer to the Swing Loan Bank in
immediately available funds the amount of its participation and upon receipt
thereof the Swing Loan Bank will deliver to such Bank a Swing Loan
participation certificate dated the date of receipt of such funds and in such
amount.

                      (f) Whenever at any time after the Swing Loan Bank has
received from any Bank such Bank's participating interest in a Swing Loan, the
Swing Loan Bank receives any payment on account thereof, the Swing Loan Bank
will distribute to such Bank its participating interest in such amount
(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 Loan Bank is required to be returned, such Bank will return to the Swing
Loan Bank any portion thereof previously distributed by the Swing Loan Bank to
it.

                      (g) Each Bank's obligation to fund a Loan as provided in
Section 2.4A(d) or to purchase participating interests pursuant to Section
2.4A(e) shall be absolute and unconditional and shall not be affected by any
circumstance, including, without limitation, (i) any setoff, counterclaim,
recoupment, defense or other right which such Bank or the Borrowers or
Guarantors may have against the Swing Loan Bank, the Borrowers or Guarantors or
anyone else for any reason 


                                     -19-
<PAGE>   21

whatsoever; (ii) the occurrence or continuance of a Default or an Event of
Default; (iii) any adverse change in the condition (financial or otherwise) of
the Borrowers or Guarantors or any of their respective Subsidiaries; (iv) any
breach of this Agreement or any of the other Loan Documents by the Borrowers or
Guarantors or any Bank; or (v) any other circumstance, happening or event
whatsoever, whether or not similar to any of the foregoing. Any portions of a
Swing Loan not so purchased or converted may be treated by the Swing Loan Bank
as a Loan which was not funded by the non-purchasing Bank as contemplated by
Section 2.7 and Section 12.4. Each Swing Loan, once so sold or converted, shall
cease to be a Swing Loan for the purposes of this Agreement, but shall be a
Loan made by each Bank under its Commitment.

         Section 2.5. Interest on Loans

                      (a) Each Base Rate Loan shall bear interest for the
period commencing with the Drawdown Date thereof and ending on the date on
which such Base Rate Loan is repaid or converted to a LIBOR Rate Loan at the
rate per annum equal to the sum of the Applicable Margin plus the Base Rate.

                      (b) Each LIBOR Rate Loan shall bear interest for the
period commencing with the Drawdown Date thereof and ending on the last day of
the Interest Period with respect thereto at the rate per annum equal to the sum
of the Applicable Margin plus the LIBOR Rate determined for such Interest
Period.

                      (c) The Borrowers promise to pay interest on each Loan in
arrears on each Interest Payment Date with respect thereto. In the event that
any additional interest becomes due and payable for any period with respect to
a Loan as a result of a change in the Applicable Margin, and the interest for
such period has previously been paid by the Borrowers, the Borrowers shall pay
to the Agent for the account of the Banks the amount of such increase within
ten (10) days of demand.

                      (d) Base Rate Loans and LIBOR Rate Loans may be converted
to Loans of the other Type as provided in Section 4.1.

         Section 2.6. Requests for Loans. Except with respect to the initial
Loan on the Closing Date and Swing Loans, the Borrowers (a) shall notify the
Agent of a potential request for a Loan as soon as possible, and (b) shall give
to the Agent written notice in the form of Exhibit H hereto (or telephonic
notice confirmed in writing in the form of Exhibit H hereto) of each Loan
requested hereunder (a "Loan Request") no less than five (5) Business Days
prior to the proposed Drawdown Date. Each such notice shall specify with
respect to the requested Loan the proposed principal amount, Drawdown Date,
Interest Period (if applicable) and Type. Each such notice shall also contain
(i) a statement as to the purpose for which such advance shall be used (which
purpose shall be in accordance with the terms of Section 7.11), and (ii) a
certification by the chief financial or chief accounting officer of the sole
general partner of WDOP and the chief financial or chief accounting officer of
Walden that the Borrowers are and will be in compliance with all covenants
under the Loan Documents after giving effect to the making of such Loan.
Promptly upon receipt of any such notice, the Agent shall notify each of the
Banks thereof. Except as 


                                     -20-
<PAGE>   22

provided in this Section 2.6, each such Loan Request shall be irrevocable and
binding on the Borrowers and shall obligate the Borrowers to accept the Loan
requested from the Banks on the proposed Drawdown Date, provided that, in
addition to the Borrowers' other remedies against any Bank which fails to
advance its proportionate share of a requested Loan, such Loan Request may be
revoked by the Borrowers by notice received by the Agent no later than the
Drawdown Date if any Bank fails to advance its proportionate share of the
requested Loan in accordance with the terms of this Agreement, provided further
that the Borrowers shall be liable in accordance with the terms of this
Agreement to any Bank which is prepared to advance its proportionate share of
the requested Loan for any costs, expenses or damages incurred by such Bank as
a result of the Borrowers' election to revoke such Loan Request. Nothing herein
shall prevent the Borrowers from seeking recourse against any Bank that fails
to advance its proportionate share of a requested Loan as required by this
Agreement. The Borrowers may without cost or penalty revoke a Loan Request by
delivering notice thereof to each of the Banks no later than three (3) Business
Days prior to the Drawdown Date. Each Loan Request shall be (a) for a Base Rate
Loan in a minimum aggregate amount of $1,000,000 or an integral multiple of
$100,000 in excess thereof, or (b) for a LIBOR Rate Loan in a minimum aggregate
amount of $2,000,000 or an integral multiple of $100,000 in excess thereof;
provided, however, that there shall be no more than ten (10) LIBOR Rate Loans
outstanding at any one time.

         Section 2.7. Funds for Loans.

                      (a) Not later than 11:00 a.m. (Boston time) on the
proposed Drawdown Date of any Loans (other than Swing Loans), each of the Banks
will make available to the Agent, at the Agent's Head Office, in immediately
available funds, the amount of such Bank's Commitment Percentage of the amount
of the requested Loans which may be disbursed pursuant to Section 2.1. Upon
receipt from each Bank of such amount, and upon receipt of the documents
required by Section 10 and Section 11 and the satisfaction of the other
conditions set forth therein, to the extent applicable, the Agent will make
available to the Borrowers the aggregate amount of such Loans made available to
the Agent by the Banks by crediting such amount to the account of the Borrowers
maintained at the Agent's Head Office. The failure or refusal of any Bank to
make available to the Agent at the aforesaid time and place on any Drawdown
Date the amount of its Commitment Percentage of the requested Loans shall not
relieve any other Bank from its several obligation hereunder to make available
to the Agent the amount of such other Bank's Commitment Percentage of any
requested Loans, including any additional Loans that may be requested subject
to the terms and conditions hereof to provide funds to replace those not
advanced by the Bank so failing or refusing, provided that the Borrowers may by
notice received by the Agent no later than the Drawdown Date refuse to accept
any Loan which is not fully funded in accordance with the Borrowers' Loan
Request subject to the terms of Section 2.6. In the event of any such failure
or refusal, the Banks not so failing or refusing shall be entitled to a
priority position as against the Bank or Banks so failing or refusing for such
Loans as provided in Section 12.4.

                      (b) Unless Agent shall have been notified by any Bank
prior to the applicable Drawdown Date that such Bank will not make available to
Agent such Bank's pro rata share of a proposed Loan, Agent may in its
discretion assume that such Bank has made such Loan available 


                                     -21-
<PAGE>   23

to Agent in accordance with the provisions of this Agreement and Agent may, if
it chooses, in reliance upon such assumption make such Loan available to
Borrowers, and such Bank shall be liable to the Agent for the amount of such
advance.

         Section 3. REPAYMENT OF THE LOANS.

         Section 3.1. Stated Maturity. The Borrowers promise to pay on the
Maturity Date and there shall become absolutely due and payable on the Maturity
Date, all of the Loans outstanding on such date, together with any and all
accrued and unpaid interest thereon.

         Section 3.2. Mandatory Prepayments.

                      (a) If at any time the aggregate outstanding principal
amount of the Loans exceeds the Total Commitment, the Borrowing Base or the
Collateral Borrowing Base, then the Borrowers shall immediately pay the amount
of such excess to the Agent for the respective accounts of the Banks for
application to the Loans, except that the amount of any Swing Loans shall be
paid solely to the Swing Loan Bank.

                      (b) All of the Borrowers' interest in the gross proceeds
of each and every sale or refinancing of real estate assets of the Borrowers
and their respective Subsidiaries (whether held directly or indirectly), less
all reasonable costs, expenses and commissions paid to unrelated parties and
less any Indebtedness (other than the Obligations) secured by such asset to be
satisfied as a part of such sale or refinance, shall be promptly paid by the
Borrowers to the Agent for the account of the Banks as a prepayment of the
Loans to the extent of the outstanding balance of the Loans.

         Section 3.3. Optional Prepayments. The Borrowers shall have the right,
at their election, to prepay the outstanding amount of the Loans, as a whole or
in part, at any time without penalty or premium; provided, that the full or
partial prepayment of the outstanding amount of any LIBOR Rate Loans pursuant
to this Section 3.3 may be made only on the last day of the Interest Period
relating thereto except as otherwise required pursuant to Section 4.7. The
Borrowers shall give the Agent, no later than 10:00 a.m., Boston time, at least
five Business Days prior written notice of any prepayment pursuant to this
Section 3.3, in each case specifying the proposed date of payment of Loans and
the principal amount to be paid. Notwithstanding the foregoing, no prior notice
shall be required for the prepayment of any Swing Loan.

         Section 3.4. Partial Prepayments. Each partial prepayment of the Loans
under Section 3.2 and Section 3.3 shall be in an integral multiple of $100,000,
shall be accompanied by the payment of accrued interest on the principal
prepaid to the date of payment and, after payment of such interest, shall be
applied, in the absence of instruction by the Borrowers, first to the principal
of any Outstanding Swing Loans, and next to the principal of Base Rate Loans
and then to the principal of LIBOR Rate Loans.

         Section 3.5. Effect of Prepayments. Amounts of the Loans prepaid under
Section 3.2 and Section 3.3 prior to the Maturity Date may be reborrowed as
provided in Section 2.


                                     -22-
<PAGE>   24

         Section 3.6. Proceeds from Debt or Equity Offering. Unless otherwise
approved by the Majority Banks, the Borrowers shall cause all gross proceeds of
each and every Debt Offering and Equity Offering, less all reasonable costs,
fees, expenses, underwriting commissions, fees and discounts incurred in
connection therewith, to be paid by the Borrowers to the Agent for the account
of the Banks as a prepayment of the Loans within thirty (30) days of the date
of such offering to the extent of the outstanding balance of the Loans.

         Section 4. CERTAIN GENERAL PROVISIONS.

         Section 4.1. Conversion Options.

                      (a) The Borrowers may elect from time to time to convert
any outstanding Loan to a Loan of another Type and such Loan shall thereafter
bear interest as a Base Rate Loan or a LIBOR Rate Loan, as applicable; provided
that (i) with respect to any such conversion of a LIBOR Rate Loan to a Base
Rate Loan, the Borrowers shall give the Agent at least three Business Days'
prior written notice of such election, and such conversion shall only be made
on the last day of the Interest Period with respect to such LIBOR Rate Loan;
(ii) with respect to any such conversion of a Base Rate Loan to a LIBOR Rate
Loan, the Borrowers shall give the Agent at least four LIBOR Business Days'
prior written notice of such election and the Interest Period requested for
such Loan, the principal amount of the Loan so converted shall be in a minimum
aggregate amount of $2,000,000 or an integral multiple of $100,000 in excess
thereof and, after giving effect to the making of such Loan, there shall be no
more than ten (10) LIBOR Rate Loans outstanding at any one time; and (iii) no
Loan may be converted into a LIBOR Rate Loan when any Default or Event of
Default has occurred and is continuing. Promptly upon receipt of any such
Conversion Request, the Agent shall notify each of the Banks thereof. All or
any part of the outstanding Loans of any Type may be converted as provided
herein, provided that no partial conversion shall result in a Base Rate Loan in
an aggregate principal amount of less than $1,000,000 or a LIBOR Rate Loan in
an aggregate principal amount of less than $2,000,000 and that the aggregate
principal amount of each Loan shall be in an integral multiple of $100,000. On
the date on which such conversion is being made, each Bank shall take such
action as is necessary to transfer its Commitment Percentage of such Loans to
its Domestic Lending Office or its LIBOR Lending Office, as the case may be.
Each Conversion Request relating to the conversion of a Base Rate Loan to a
LIBOR Rate Loan shall be irrevocable by the Borrowers.

                      (b) Any Loan may be continued as such Type upon the
expiration of an Interest Period with respect thereto by compliance by the
Borrowers with the terms of Section 4.1; provided that no LIBOR Rate Loan may
be continued as such when any Default or Event of Default has occurred and is
continuing, but shall be automatically converted to a Base Rate Loan on the
last day of the Interest Period relating thereto ending during the continuance
of any Default or Event of Default.

                      (c) In the event that the Borrowers do not notify the
Agent of their election hereunder with respect to any Loan, such Loan shall be
automatically converted to a Base Rate Loan at the end of the applicable
Interest Period.

         Section 4.2. Closing Fee.

         (a) The Borrowers have previously paid to BKB certain closing and
structuring fees pursuant to the Original Credit Agreement, which fees are
non-refundable.

         (b) The Borrowers agree to pay to BKB certain fees for services
rendered or to be rendered in connection with the Loan as provided pursuant to
the Agreement Regarding Fees. Upon payment of such fees, BKB shall pay to the
Banks a closing fee in accordance with their separate agreement. All such fees
shall be non-refundable.

         Section 4.3. Agent's Fee. The Borrowers shall pay to the Agent, for
the Agent's own account, an annual Agent's fee as provided in the Agreement
Regarding Fees. The Agent's fee shall be payable quarterly in arrears on the
first day of each calendar quarter for the immediately preceding calendar
quarter or portion thereof. The Agent's fee shall also be paid upon the
Maturity Date or earlier termination of the Commitments. The Agent's fee for
any partial quarter shall be prorated.

         Section 4.4. Funds for Payments.

                      (a) All payments of principal, interest, facility fees,
Agent's fees, closing fees, and any other amounts due hereunder or under any of
the other Loan Documents shall be made to the Agent, for the respective
accounts of the Banks and the Agent, as the case may be, at the Agent's Head
Office, not later than 11:00 a.m. (Boston time) on the day when due, in each
case in immediately available funds. The Agent is hereby authorized to charge
the account of the Borrowers with BKB, on the dates when the amount thereof
shall become due and payable, with the amounts of the principal of and interest
on the Loans and all fees, charges, expenses and other amounts owing to the
Agent and/or the Banks (including the Swing Loan Bank) under the Loan
Documents.

                      (b) All payments by the Borrowers hereunder and under any
of the other Loan Documents shall be made without setoff or counterclaim and
free and clear of and without deduction for any taxes, levies, imposts, duties,
charges, fees, deductions, withholdings, compulsory loans, restrictions or
conditions of any nature now or hereafter imposed or levied by any jurisdiction
or any political subdivision thereof or taxing or other authority therein
unless the Borrowers are compelled by law to make such deduction or
withholding. If any such obligation is imposed upon the Borrowers with respect
to any amount payable by it hereunder or under any of the other Loan Documents,
the Borrowers will pay to the Agent, for the account of the Banks (including
the Swing Loan Bank) or (as the case may be) the Agent, on the date on which
such amount is due and payable hereunder or under such other Loan Document,
such additional amount in Dollars as shall be necessary to enable the Banks or
the Agent to receive the same net amount which the Banks or the Agent would
have received on such due date had no such obligation been imposed upon the
Borrowers. The Borrowers will deliver promptly to the Agent certificates or
other valid vouchers for all taxes or other charges deducted from or paid with
respect to payments made by the Borrowers hereunder or under such other Loan
Document.


                                     -24-
<PAGE>   26

         Section 4.5. Computations. All computations of interest on the Loans
and of other fees to the extent applicable shall be based on a 360-day year and
paid for the actual number of days elapsed. Except as otherwise provided in the
definition of the term "Interest Period" with respect to LIBOR Rate Loans,
whenever a payment hereunder or under any of the other Loan Documents becomes
due on a day that is not a Business Day, the due date for such payment shall be
extended to the next succeeding Business Day, and interest shall accrue during
such extension. The outstanding amount of the Loans as reflected on the records
of the Agent from time to time shall be considered prima facie evidence of such
amount.

         Section 4.6. Inability to Determine LIBOR Rate. In the event that,
prior to the commencement of any Interest Period relating to any LIBOR Rate
Loan, the Agent shall determine that adequate and reasonable methods do not
exist for ascertaining the LIBOR Rate for such Interest Period, the Agent shall
forthwith give notice of such determination (which shall be conclusive and
binding on the Borrowers and the Banks) to the Borrowers and the Banks. In such
event (a) any Loan Request with respect to LIBOR Rate Loans shall be
automatically withdrawn and shall be deemed a request for Base Rate Loans, and
(b) each LIBOR Rate Loan will automatically, on the last day of the then
current Interest Period thereof, become a Base Rate Loan, and the obligations
of the Banks to make LIBOR Rate Loans shall be suspended until the Agent
determines that the circumstances giving rise to such suspension no longer
exist, whereupon the Agent shall so notify the Borrowers and the Banks.

         Section 4.7. Illegality. Notwithstanding any other provisions herein,
if any present or future law, regulation, treaty or directive or the
interpretation or application thereof shall make it unlawful, or any central
bank or other governmental authority having jurisdiction over a Bank or its
LIBOR Lending Office shall assert that it is unlawful, for any Bank to make or
maintain LIBOR Rate Loans, such Bank shall forthwith give notice of such
circumstances to the Agent and the Borrowers and thereupon (a) the commitment
of the Banks to make LIBOR Rate Loans or convert Loans of another type to LIBOR
Rate Loans shall forthwith be suspended and (b) the LIBOR Rate Loans then
outstanding shall be converted automatically to Base Rate Loans on the last day
of each Interest Period applicable to such LIBOR Rate Loans or within such
earlier period as may be required by law.

         Section 4.8. Additional Interest. If any LIBOR Rate Loan or any
portion thereof is repaid or is converted to a Base Rate Loan for any reason on
a date which is prior to the last day of the Interest Period applicable to such
LIBOR Rate Loan, the Borrowers will pay to the Agent upon demand for the
account of the Banks in accordance with their respective Commitment Percentages
(or to the Swing Loan Bank with respect to a Swing Loan), in addition to any
amounts of interest otherwise payable hereunder, any amounts required to
compensate the Banks for any losses, costs or expenses which may reasonably be
incurred as a result of such payment or conversion, including, without
limitation, an amount equal to daily interest for the unexpired portion of such
Interest Period on the LIBOR Rate Loan or portion thereof so repaid or
converted at a per annum rate equal to the excess, if any, of (a) the interest
rate calculated on the basis of the LIBOR Rate applicable to such LIBOR Rate
Loan minus (b) the yield obtainable by the Agent upon the purchase of debt
securities customarily issued by the Treasury of the United States of America
which have a maturity date most closely approximating the last day of such


                                     -25-
<PAGE>   27

Interest Period (it being understood that the purchase of such securities shall
not be required in order for such amounts to be payable and that a Bank shall
not be obligated or required to have actually obtained funds at the LIBOR Rate
or to have actually reinvested such amount as described above).

         Section 4.9. Additional Costs, Etc. Notwithstanding anything herein to
the contrary, if any present or future applicable law, which expression, as
used herein, includes statutes, rules and regulations thereunder and legally
binding interpretations thereof by any competent court or by any governmental
or other regulatory body or official with appropriate jurisdiction charged with
the administration or the interpretation thereof and requests, directives,
instructions and notices at any time or from time to time hereafter made upon
or otherwise issued to any Bank or the Agent by any central bank or other
fiscal, monetary or other authority (whether or not having the force of law),
shall:

                      (a) subject any Bank or the Agent to any tax, levy,
impost, duty, charge, fee, deduction or withholding of any nature with respect
to this Agreement, the other Loan Documents, such Bank's Commitment (including
the Swing Loan Commitment) or the Loans (other than taxes based upon or
measured by the income or profits of such Bank or the Agent), or

                      (b) materially change the basis of taxation (except for
changes in taxes on income or profits) of payments to any Bank of the principal
of or the interest on any Loans or any other amounts payable to any Bank under
this Agreement or the other Loan Documents, or

                      (c) impose or increase or render applicable any special
deposit, reserve, assessment, liquidity, capital adequacy or other similar
requirements (whether or not having the force of law) against assets held by,
or deposits in or for the account of, or loans by, or letters of credit from,
or commitments of an office of any Bank, or

                      (d) impose on any Bank or the Agent any other conditions
or requirements with respect to this Agreement, the other Loan Documents, the
Loans, such Bank's Commitment (including the Swing Loan Commitment), or any
class of loans or commitments of which any of the Loans or such Bank's
Commitment (including the Swing Loan Commitment) forms a part; and the result
of any of the foregoing is

                          (i) to increase the cost to any Bank of making, 
funding, issuing, renewing, extending or maintaining any of the Loans or such
Bank's Commitment (including the Swing Loan Commitment), or

                          (ii) to reduce the amount of principal, interest or 
other amount payable to such Bank or the Agent hereunder on account of such
Bank's Commitment (including the Swing Loan Commitment) or any of the Loans, or

                          (iii) to require such Bank or the Agent to make any
payment or to forego any interest or other sum payable hereunder, the amount of
which payment or foregone 


                                     -26-
<PAGE>   28

interest or other sum is calculated by reference to the gross amount of any sum
receivable or deemed received by such Bank or the Agent from the Borrowers
hereunder,

then, and in each such case, the Borrowers will, within fifteen (15) days of
demand made by such Bank or (as the case may be) the Agent at any time and from
time to time and as often as the occasion therefor may arise, pay to such Bank
or the Agent such additional amounts as such Bank or the Agent shall determine
in good faith to be sufficient to compensate such Bank or the Agent for such
additional cost, reduction, payment or foregone interest or other sum. Each
Bank and the Agent in determining such amounts may use any reasonable averaging
and attribution methods, generally applied by such Bank or the Agent.

         Section 4.10. Capital Adequacy. If after the date hereof any Bank
determines that (a) the adoption of or change in any law, rule, regulation or
guideline regarding capital requirements for banks or bank holding companies or
any change in the interpretation or application thereof by any governmental
authority charged with the administration thereof, or (b) compliance by such
Bank or its parent bank holding company with any guideline, request or
directive of any such entity regarding capital adequacy (whether or not having
the force of law), has the effect of reducing the return on such Bank's or such
holding company's capital as a consequence of such Bank's commitment to make
Loans hereunder to a level below that which such Bank or holding company could
have achieved but for such adoption, change or compliance (taking into
consideration such Bank's or such holding company's then existing policies with
respect to capital adequacy and assuming the full utilization of such entity's
capital) by any amount deemed by such Bank to be material, then such Bank may
notify the Borrowers thereof. The Borrowers agree to pay to such Bank the
amount of such reduction in the return on capital as and when such reduction is
determined, upon presentation by such Bank of a statement of the amount setting
forth the Bank's calculation thereof. In determining such amount, such Bank may
use any reasonable averaging and attribution methods.

         Section 4.11. Indemnity of Borrowers. The Borrowers agree to indemnify
each Bank and to hold each Bank harmless from and against any loss, cost or
expense that such Bank may sustain or incur as a consequence of (a) default by
the Borrowers in payment of the principal amount of or any interest on any
LIBOR Rate Loans as and when due and payable, including any such loss or
expense arising from interest or fees payable by such Bank to lenders of funds
obtained by it in order to maintain its LIBOR Rate Loans, or (b) default by the
Borrowers in making a borrowing or conversion after the Borrowers have given
(or are deemed to have given) a Loan Request or a Conversion Request.

         Section 4.12. Interest on Overdue Amounts; Late Charge. Overdue
principal and (to the extent permitted by applicable law) interest on the Loans
and all other overdue amounts payable hereunder or under any of the other Loan
Documents shall bear interest payable on demand at a rate per annum equal to
five percent (5.00%) above the Base Rate until such amount shall be paid in
full (after as well as before judgment). In addition, the Borrowers shall pay a
late charge equal to three percent (3%) of any amount of interest and/or
principal payable on the Loans or any other amounts payable hereunder or under
the Loan Documents, which is not paid within ten days of the date when due.


                                     -27-
<PAGE>   29

         Section 4.13. Certificate. A certificate setting forth any amounts
payable pursuant to Section 4.8, Section 4.9, Section 4.10, Section 4.11 or
Section 4.12 and a brief explanation of such amounts which are due, submitted
by any Bank or the Agent to the Borrowers, shall be conclusive in the absence
of manifest error.

         Section 4.14. Limitation on Interest. Notwithstanding anything in this
Agreement to the contrary, all agreements between the Borrowers and the Banks
and the Agent, whether now existing or hereafter arising and whether written or
oral, are hereby limited so that in no contingency, whether by reason of
acceleration of the maturity of any of the Obligations or otherwise, shall the
interest contracted for, charged or received by the Banks exceed the maximum
amount permissible under applicable law. If, from any circumstance whatsoever,
interest would otherwise be payable to the Banks in excess of the maximum
lawful amount, the interest payable to the Banks shall be reduced to the
maximum amount permitted under applicable law; and if from any circumstance the
Banks shall ever receive anything of value deemed interest by applicable law in
excess of the maximum lawful amount, an amount equal to any excessive interest
shall be applied to the reduction of the principal balance of the Obligations
and to the payment of interest or, if such excessive interest exceeds the
unpaid balance of principal of the Obligations, such excess shall be refunded
to the Borrowers. All interest paid or agreed to be paid to the Banks shall, to

cost and expense, with respect to each Unencumbered Operating Property. The
Borrowers shall upon demand pay the cost of any such mortgagee's title
insurance policy, the cost of any updated UCC searches, all recording costs and
fees, and any and all intangible taxes or other documentary or mortgage taxes,
assessments or charges which are demanded in connection with the recording of

                   (e) The Borrowers may elect by the delivery of written notice
to the Agent to remove any Unencumbered Operating Property from the Borrowing
Base and the Collateral Borrowing Base in order to sell such asset or to
encumber such asset as permitted pursuant to Section 8.2, provided that no

previously been recorded pursuant hereto. Such request shall be accompanied by
a statement certified by the principal financial or accounting officer of
Walden that no Default or Event of Default exists or will exist following the
requested release and a Compliance Certificate demonstrating that the Borrowers
will be in compliance with their covenants referred to therein after giving
effect to such release and sale or refinance. Upon the satisfaction of the
foregoing conditions, the Agent shall return the Escrowed Security Documents
relating to such Unencumbered Operating Property to the applicable Borrower.

                   (f) The Majority Banks may, in their discretion, elect by the
delivery of written notice to the Borrowers to cause the Borrowers to remove
any Unencumbered Operating Property from the Collateral Borrowing Base and to

transporters and facilities have been and are, to the best of the Borrowers'
knowledge operating in compliance with such permits and applicable
Environmental Laws. Upon the receipt by the Agent of any such disclosure, the
Agent shall promptly notify the Banks thereof.

                       (d) Neither the Borrowers, their respective Subsidiaries
nor any Real Estate of such Person is subject to any applicable Environmental
Law requiring the performance of Hazardous Substances site assessments, or the
removal or remediation of Hazardous Substances, or the giving of notice to any
governmental agency or the recording or delivery to other Persons of an
environmental disclosure document or statement by virtue of the transactions
set forth herein and contemplated hereby, or as a condition to the recording of
the Escrowed Security Documents or to the effectiveness of any other
transactions contemplated hereby.

         Section 6.18. Subsidiaries. Schedule 6.18 sets forth all of the
Subsidiaries of WDOP and Walden. The form and jurisdiction of organization of
each of the Subsidiaries, and WDOP's and Walden's ownership interest therein,
is set forth in said Schedule 6.18.

         Section 6.19. Loan Documents and the Guarantors. All of the
representations and warranties of the Borrowers and the Guarantors made in this
Agreement and the other Loan Documents or any document or instrument delivered
to the Agent or the Banks pursuant to or in connection with any of such Loan
Documents are true and correct in all material respects, and none of the


                                     -37-
<PAGE>   39

Borrowers nor the Guarantors has failed to disclose such information as is
necessary to make such representations and warranties not misleading.

         Section 6.20. Property. All of the Borrowers', the Guarantors' and
their respective Subsidiaries' properties are in good repair and condition,
subject to ordinary wear and tear, other than with respect to deferred
maintenance existing as of the date of acquisition of such property as
permitted in this Section 6.20. The Borrowers further have completed or caused
to be completed an appropriate investigation of the environmental condition of
each such property as of the later of the date of the Borrowers', the
Guarantors' or such Subsidiaries' purchase thereof or the date upon which such
property was last security for Indebtedness of such Borrower, such Guarantor or
such Subsidiary, including preparation of a "Phase I" report and, if
appropriate, a "Phase II" report, in each case prepared by a recognized
environmental engineer in accordance with customary standards which discloses
that such property is not in violation of the representations and covenants set
forth in this Agreement, unless such violation has been disclosed in writing to
the Agent and satisfactory remediation actions are being taken. There are no
unpaid or outstanding real estate or other taxes or assessments on or against
any property of any Borrower, any Guarantor or any of their respective
Subsidiaries which are payable by such Person (except only real estate or other
taxes or assessments, that are not yet due and payable). There are no pending
eminent domain proceedings against any property of Borrowers, the Guarantors or
their respective Subsidiaries or any part thereof, and, to the knowledge of the
Borrowers, no such proceedings are presently threatened or contemplated by any
taking authority which may individually or in the aggregate have any materially
adverse effect on the business or financial condition of the Borrowers or the
Guarantors. None of the property of Borrowers, the Guarantors or their
respective Subsidiaries is now damaged or injured as a result of any fire,
explosion, accident, flood or other casualty in any manner which individually
or in the aggregate would have any materially adverse effect on the business or
financial condition of the Borrowers or the Guarantors. The Real Estate owned
by Walden, WDOP and their respective Subsidiaries is set forth on Schedule 6.20
hereto.

         Section 6.21. Brokers. None of the Borrowers nor any of their
respective Subsidiaries has engaged or otherwise dealt with any broker, finder
or similar entity in connection with this Agreement or the Loans contemplated
hereunder.

         Section 6.22. Other Debt. None of the Borrowers, the General Partner,
the Guarantors or any of their respective Subsidiaries is in default in the
payment of any other Indebtedness or under any agreement, mortgage, deed of
trust, security agreement, financing agreement, indenture or lease to which any
of them is a party. None of the Borrowers is a party to or bound by any
agreement, instrument or indenture that may require the subordination in right
or time of payment of any of the Obligations to any other indebtedness or
obligation of such Borrower. The Borrowers have provided to the Agent copies of
all agreements, mortgages, deeds of trust, financing agreements or other
material agreements binding upon Borrowers, the General Partner, the Guarantors
or their respective properties and entered into by such Person as of the date
of this Agreement with respect to any Indebtedness of such Person. Schedule
6.22 hereto sets forth all of the Indebtedness of the type described in Section
8.1(g) and (h) of the Borrowers and their respective Subsidiaries as of the
date hereof.

         Section 6.23. Solvency. As of the Closing Date and after giving effect
to the transactions contemplated by this Agreement and the other Loan
Documents, including all of the Loans made or to be made hereunder, neither the
Borrowers nor any Guarantor is insolvent on a balance sheet basis such that the
sum of such Person's assets exceeds the sum of such Person's liabilities, each
Borrower and each Guarantor is able to pay its debts as they become due, and
each Borrower and each Guarantor has sufficient capital to carry on its
business.

         Section 6.24. Partners. Walden is the sole general partner of WDOP and
owns a 1% partnership interest in WDOP. Walden Operating, Inc. is the sole
general partner of WROP and owns a 1% partnership interest in WROP. WDN
Properties, Inc. is a limited partner of WDOP and WROP and owns an
approximately 58% partnership interest in WDOP and a 77.3784% partnership
interest in WROP. WROP is a limited partner of WDOP and owns an approximately
11% partnership interest in WDOP. Walden owns one hundred percent (100%) of the
issued and outstanding shares of stock of WDN Properties, Inc. and Walden
Operating, Inc.

         Section 6.25. No Fraudulent Intent. Neither the execution and delivery
of this Agreement or any of the other Loan Documents nor the performance of any
actions required hereunder or thereunder is being undertaken by any Borrower or
any Guarantor with or as a result of any actual intent by any of such Persons
to hinder, delay or defraud any entity to which any of such Persons is now or
will hereafter become indebted.

         Section 6.26. Transaction in best interests of Borrowers;
Consideration. The transaction evidenced by this Agreement and the other Loan
Documents is in the best interests of the Borrowers and the creditors of such
Persons. The direct and indirect benefits to inure to the Borrowers pursuant to
this Agreement and the other Loan Documents constitute substantially more than
"reasonably equivalent value" (as such term is used in Section 548 of the
Bankruptcy Code) and "valuable consideration," "fair value," and "fair
consideration" (as such terms are used in any applicable state fraudulent
conveyance law), in exchange for the benefits to be provided by the Borrowers
pursuant to this Agreement and the other Loan Documents, and but for the
willingness of the Borrowers to be jointly and severally liable as co-borrowers
for the Loan, Borrowers would be unable to obtain the financing contemplated
hereunder which financing will enable the Borrowers and their respective
Subsidiaries to have available financing to conduct and expand their business.

         Section 6.27. Year 2000 Compliant. Borrowers have (i) undertaken a
detailed inventory, review and assessment of all areas within their business
and operations that could be adversely affected by the failure to be Year 2000
Compliant on a timely basis, (ii) developed a detailed plan and timeline for
becoming Year 2000 Compliant on a timely basis, and (iii) to date, implemented
that plan in accordance with that timetable in all material aspects. Borrowers
reasonably anticipate that they will be Year 2000 Compliant by September 30,
1999 or such earlier date as is necessary to avoid any material disruption of
Borrowers' business and have committed and will commit reasonably adequate
resources to be Year 2000 Compliant.

         Section 7.5. Notices.

                      (a) Defaults. The Borrowers will promptly notify the Agent
in writing of the occurrence of any Default or Event of Default. If any Person
shall give any notice or take any other action in respect of a claimed default
(whether or not constituting an Event of Default) under this Agreement or under
any note, evidence of indebtedness, indenture or other obligation to which or
with respect to which the Borrowers, the General Partner, the Guarantors or any
of their respective Subsidiaries is a party or obligor, whether as principal or
surety, and such default would permit the holder of such note or obligation or
other evidence of indebtedness to accelerate the maturity thereof, which
acceleration would have a material adverse effect on the Borrowers, the General
Partner or the Guarantors or the existence of which claimed default might
become an Event of Default under Section 12.1(g), the Borrowers shall forthwith
give written notice thereof to the Agent and each of the Banks, describing the
notice or action and the nature of the claimed default.

                      (b) Environmental Events. The Borrowers will promptly give

Hazardous Substances at or from any Real Estate; (ii) of any violation of any
Environmental Law that either Borrower, the Guarantors or any of their
respective Subsidiaries reports in writing or is reportable by such Person in
writing (or for which any written report supplemental to any oral report is
made) to any federal, state or local environmental agency; and (iii) upon
becoming aware thereof, of any inquiry, proceeding, investigation, or other
action, including a notice from any agency of potential environmental
liability, of any federal, state or local environmental agency or board, that
in either case involves any Real Estate or has the potential to materially
affect the assets, liabilities, financial conditions or operations of such
Person or the Agent's liens on the Collateral pursuant to the Security
Documents in the event the same are recorded as provided herein.

                      (c) Notice of Litigation and Judgments. The Borrowers will

to become a party involving an uninsured claim against such Person that could
reasonably be expected to have a materially adverse effect on either Borrower
or any Guarantor and stating the nature and status of such litigation or
proceedings. The Borrowers will give notice to the Agent, in writing, in form
and detail satisfactory to the Agent and each of the Banks, within ten days of
any judgment not covered by insurance, whether final or otherwise, against a
Borrower, the General Partner, a Guarantor or any of their respective
Subsidiaries in an amount in excess of $1,000,000.00.


                                     -43-
<PAGE>   45

                      (d) Notice of Proposed Sales, Encumbrances, Refinance or
Transfer. The Borrowers will give notice to the Agent of any proposed or
completed sale, encumbrance, refinance or transfer of any Real Estate within
any fiscal quarter of the Borrowers, such notice to be submitted together with
the Compliance Certificate provided or required to be provided to the Banks
under Section 7.4 with respect to such fiscal quarter. The Compliance
Certificate shall with respect to any proposed or completed sale, encumbrance,
refinance or transfer be adjusted in the best good-faith estimate of the
Borrowers to give effect to such sale, encumbrance, refinance or transfer and
demonstrate that no Default or Event of Default with respect to the covenants
referred to therein shall exist after giving effect to such sale, encumbrance,
refinance or transfer. Notwithstanding the foregoing, in the event of any sale,
encumbrance, refinance or transfer of any Real Estate involving an aggregate
amount in excess of $25,000,000.00, the Borrowers shall promptly give notice to
the Agent of such transaction, which notice shall be accompanied by a
certification of the chief financial officer of Walden for itself and as the
sole general partner of WDOP that no Default or Event of Default shall exist
after giving affect to such event.

                      (e) Notification of Claims Against Collateral. The
Borrowers will, immediately upon becoming aware thereof, notify the Agent in
writing of any setoff, claims (including environmental claims), withholdings or
other defenses to which any of the Collateral (including for the purposes
hereof any collateral subject to the Escrowed Security Documents), or the
rights of the Agent or the Banks with respect to the Collateral (including for
the purposes hereof any collateral subject to the Escrowed Security Documents),
are subject.

                      (f) Notification of Banks. Promptly after receiving any
notice under this Section 7.5, the Agent will forward a copy thereof to each of
the Banks, together with copies of any certificates or other written
information that accompanied such notice.

         Section 7.6. Existence; Maintenance of Properties.

                      (a) The Borrowers will do or cause to be done all things
necessary to preserve and keep in full force and effect its existence as a
Delaware limited partnership or Maryland corporation, as applicable. The
Borrowers will cause each of their respective Subsidiaries to do or cause to be
done all things necessary to preserve and keep in full force and effect its
legal existence. Each Borrower will do or cause to be done all things necessary
to preserve and keep in full force all of its rights and franchises and those
of its Subsidiaries. Each Borrower will, and will cause each of its
Subsidiaries to, continue to engage primarily in the businesses now conducted
by it and in related businesses.

                      (b) Irrespective of whether proceeds of the Loans are
available for such purpose, each Borrower (i) will cause all of its properties
and those of its Subsidiaries used or useful in the conduct of its business or
the business of its Subsidiaries to be maintained and kept in good condition,
repair and working order (ordinary wear and tear excepted) and supplied with
all necessary equipment, and (ii) will cause to be made all necessary repairs,
renewals, replacements, betterments and improvements thereof in all cases in
which the failure so to do would have a material adverse effect on the
condition of its properties or on the financial condition, assets or operations
of such Borrower and its Subsidiaries.

listed for trading and be traded on the New York Stock Exchange.

         Section 7.7. Insurance. The Borrowers will, at their expense, procure
and maintain or cause to be procured and maintained insurance covering the
Borrowers, their respective Subsidiaries and their respective properties in
such amounts and against such risks and casualties as are customary for
properties of similar character and location, due regard being given to the
type of improvements thereon, their construction, location, use and occupancy.

         Section 7.8. Taxes. The Borrowers and their respective Subsidiaries
will duly pay and discharge, or cause to be paid and discharged, before the
same shall become overdue, all taxes, assessments and other governmental
charges imposed upon each of them and upon the Real Estate, sales and
activities, or any part thereof, or upon the income or profits therefrom, as
well as all claims for labor, materials, or supplies that if unpaid might by
law become a lien or charge upon any of its property; provided that any such
tax, assessment, charge, levy or claim need not be paid if the validity or
amount thereof shall currently be contested in good faith by appropriate
proceedings and if such Borrower or such Subsidiary shall have set aside on its
books adequate reserves with respect thereto; and provided, further, that
forthwith upon the commencement of proceedings to foreclose any lien that may
have attached as security therefor, each Borrower and each Subsidiary of the
Borrowers either (i) will provide a bond issued by a surety reasonably
acceptable to the Agent and sufficient to stay all such proceedings or (ii) if
no such bond is provided, will pay each such tax, assessment, charge, levy or
claim. The Borrowers shall certify annually to the Agent that this Section 7.8
has been satisfied with respect to the Unencumbered Operating Properties.

         Section 7.9. Inspection of Properties and Books. The Borrowers shall
permit the Banks, through the Agent or any representative designated by the
Agent, at the Borrowers' expense to visit and inspect any of the properties of
the Borrowers or any of their respective Subsidiaries, to examine the books of
account of the Borrowers and their respective Subsidiaries (and to make copies
thereof and extracts therefrom) and to discuss the affairs, finances and
accounts of the Borrowers and their respective Subsidiaries with, and to be
advised as to the same by, its officers, all at such reasonable times and
intervals as the Agent or any Bank may reasonably request. The Banks shall use
good faith efforts to coordinate such visits and inspections so as to minimize
the interference with and disruption to the Borrowers' normal business
operations.

         Section 7.10. Compliance with Laws, Contracts, Licenses, and Permits.

comply in all respects with (i) all applicable laws and regulations now or
hereafter in effect wherever its business is conducted, including all
Environmental Laws, (ii) the provisions of its corporate charter, partnership
agreement or declaration of trust, as the case may be, and other charter
documents and bylaws, (iii) all agreements and instruments to which it is a
party or by which it or any of its properties may be bound, (iv) all applicable
decrees, orders, and judgments, and (v) all licenses and permits required by
applicable laws and regulations for the conduct of its business or the
ownership, use or operation of its properties. If at any time while any Loan or
Note is outstanding or the Banks have any obligation to make Loans hereunder,
any authorization, consent, approval, permit or


                                     -45-
<PAGE>   47

license from any officer, agency or instrumentality of any government shall
become necessary or required in order that the Borrowers may fulfill any of
their obligations hereunder, the Borrowers will immediately take or cause to be
taken all steps necessary to obtain such authorization, consent, approval,
permit or license and furnish the Agent and the Banks with evidence thereof.

         Section 7.11. Use of Proceeds. The Borrowers will use the proceeds of
the Loans solely to provide short-term financing (a) for the acquisition of fee
interests by WDOP in Real Estate which is utilized principally for multifamily
housing (including reasonable transaction costs related thereto) (provided that
no more than $20,000,000.00 in the aggregate for the term of the Loans may be
used by WDOP for the acquisition of fee interests in such Real Estate by
wholly-owned Subsidiaries of WDOP as provided in Section 7.16), (b) for working
capital purposes of WDOP and Walden, (c) for Investments permitted pursuant to
Section 8.3(k), and (d) for such other purposes as the Majority Banks in their

$25,000,000.00. Any repayment of a principal portion of the Loans at a time
when any amount of Loans has been advanced for the purpose described in Section

         Section 7.12. Further Assurances. The Borrowers will cooperate with,
and will cause each of the Guarantors and their respective Subsidiaries to

         Section 7.13. Management; Business Operations. The Borrowers shall

shall at all time comply with all requirements of applicable laws necessary to
maintain REIT Status and shall operate, and shall cause its Subsidiaries to
operate, their respective businesses as described in the Prospectus and in
compliance with the terms and conditions of this Agreement.

         Section 7.14. Unencumbered Operating Properties.

                       (a) The Borrowers shall at all times own Unencumbered
Operating Properties which satisfy all of the following conditions:

                           (i) the Unencumbered Operating Properties shall
         consist solely of Real Estate which has an aggregate occupancy level
         (on a portfolio basis) of at least ninety percent (90%) for the
         previous four (4) fiscal quarters of the Borrowers based on bona fide
         arms-length tenant leases requiring current rental payments; and


                                     -46-
<PAGE>   48

                           (ii) no more than thirty percent (30%) of the Asset
         Value of the Unencumbered Operating Properties may be located in any
         one city or metropolitan area (it being agreed that Dallas and Fort
         Worth and their respective suburbs shall be considered as separate
         cities for the purposes hereof).

                      (b) The Borrowers shall provide to the Agent and each of
the Banks as of the Closing Date and concurrently with the delivery of the
financial statements described in Section 7.4(a) (i) a list of the Unencumbered
Operating Properties, (ii) the certification of the chief financial or chief
accounting officer of Walden, for itself and as the sole general partner of
WDOP of the Asset Values and that such properties are in compliance with
Section 7.14(a) and Section 9.1, (iii) operating statements setting forth the
Operating Cash Flow and capital expenditures for each of the Unencumbered
Operating Properties for the previous four (4) fiscal quarters certified as
true and correct by the chief financial or chief accounting officer of Walden,
for itself and as the sole general partner of WDOP, and (iv) that the
Unencumbered Operating Properties comply with the terms of Section Section 6.17
and 6.20. In the event that all or any material portion of a property within

condemnation, then such property shall no longer be a part of the Unencumbered
Operating Properties unless and until any damage to such Real Estate is
repaired or restored, such Real Estate becomes fully operational and the Agent
shall receive evidence satisfactory to the Agent of the value and Operating
Cash Flow of such Real Estate following such repair or restoration.

         Section 7.15. Limiting Agreements.

                       (a) Neither Borrower, any Guarantor nor any of their
respective Subsidiaries shall enter into, any agreement, instrument or
transaction which has or may have the effect of prohibiting or limiting such
Borrower's or any Guarantor's ability to pledge to Agent the Unencumbered
Operating Properties, Real Estate which is owned by the Borrowers or such
Guarantors which is free and clear of all Liens other than the Liens permitted
in Section 8.2(i), (iii) and (v) or any other assets of the Borrowers or such
Guarantor as security for the Loans. Borrowers shall take, and shall cause the
Guarantors and their respective Subsidiaries to take, such actions as are
necessary to preserve the right and ability of Borrowers and the Guarantors to
pledge those Real Estate and other assets as security for the Loans without any
such pledge after the date hereof causing or permitting the acceleration (after
the giving of notice or the passage of time, or otherwise) of any other
Indebtedness of Borrowers, the Guarantors or any of their respective
Subsidiaries.

                      (b) Borrowers shall upon demand provide to the Agent such
evidence as the Agent may reasonably require to evidence compliance with this
Section 7.15, which evidence shall include, without limitation, copies of any
agreements or instruments which would in any way restrict or limit a Borrower's
or any Guarantor's ability to pledge assets as security for Indebtedness, or
which provide for the occurrence of a default (after the giving of notice or
the passage of time, or otherwise) if assets are pledged in the future as
security for Indebtedness of such Borrower or any of its Subsidiaries.

         Section 7.16. Ownership of Real Estate. Without the prior written
consent of the Majority Banks, which consent may be withheld by the Majority
Banks in their sole discretion, all interests (whether direct or indirect) of
the Borrowers, the General Partner, the Guarantors or their respective
Subsidiaries in income-producing real estate assets acquired after the Closing
Date shall be owned directly by WDOP except as permitted by Section 8.3(k).
Notwithstanding the foregoing, Walden and WDOP may acquire income-producing
real estate assets after the Closing Date (a) as provided in Section 8.11, and
(b) in a like-kind exchange of Real Estate owned by such Person as of the
Closing Date. In addition, WDOP may subject to the terms of this Agreement
acquire through a wholly-owned Subsidiary of WDOP Real Estate that is
encumbered by Indebtedness that is to be assumed by such Subsidiary in
connection with the acquisition thereof and which acquisition is financed in
part with proceeds of the Loans as provided in Section 7.11(a).

         Section 7.17. Distributions of Income to the Borrowers. Each Borrower
shall cause all of its Subsidiaries to promptly distribute to such Borrower
(but not less frequently than once each fiscal quarter of such Borrower),
whether in the form of dividends, distributions or otherwise, all profits,
proceeds or other income relating to or arising from its Subsidiaries' use,
operation, financing, refinancing, sale or other disposition of their
respective assets and properties after (a) the payment by each Subsidiary of
its Debt Service and operating expenses for such quarter and (b) the
establishment of reasonable reserves for the payment of operating expenses not
paid on at least a quarterly basis and capital improvements to be made to such
Subsidiary's assets and properties approved by such Subsidiary in the ordinary
course of business consistent with its past practices.

         Section 7.18. More Restrictive Agreements. Should any Borrower or any
Guarantor enter into or modify any agreements or documents pertaining to any
existing or future Indebtedness, Debt Offering or Equity Offering, which
agreements or documents include covenants (whether affirmative or negative),
warranties, representations, defaults or events of default (or any other
provision which may have the same practical effect as any of the foregoing)
which are individually or in the aggregate more restrictive against either
Borrower, any Guarantor or their respective Subsidiaries than those set forth
herein or in any of the other Loan Documents or which provide for a guaranty of
the obligations thereunder by a Person that is not liable for the Obligations,
the Borrowers shall promptly notify the Agent and, if requested by the Majority
Banks, the Borrowers, the Agent, and the Majority Banks shall (and if
applicable, the Borrower shall cause the Guarantors to) promptly amend this
Agreement and the other Loan Documents to include some or all of such more
restrictive provisions or provide for a guaranty of the Obligations by such
Person as determined by the Majority Banks in their sole discretion.

         Section 8. CERTAIN NEGATIVE COVENANTS OF THE BORROWERS.

times thereafter shall not exceed forty percent (40%) of Walden's Consolidated
Total Assets; and

                      (h) subject to the provisions of Section 9, secured or

Obligations) and the portion of the Indebtedness described in Section 8.1(g)
that is recourse to Walden and its Subsidiaries shall not exceed five percent
(5%) of Walden's Consolidated Total Assets (provided, however, that with

                      (i) in the event of any change in Environmental Laws
governing the assessment, release or removal of Hazardous Substances, which
change would lead a prudent lender to require additional testing to avail
itself of any statutory insurance or limited liability, take all action
(including, without limitation, the conducting of engineering tests at the sole
expense of the Borrowers) to confirm that no Hazardous Substances are or ever
were Released or disposed of on the Real Estate; and

Release or threatened Release of Hazardous Substances may have occurred,
relating to any Real Estate, or that any of the Real Estate is not in
compliance with the Environmental Laws, the Agent may at its election (and will
at the request of the 


                                     -53-
<PAGE>   55

Majority Banks) obtain such environmental assessments of such Real Estate
prepared by an environmental engineer as may be necessary or advisable for the

present in the soil or water at or adjacent to such Real Estate and (ii)
whether the use and operation of such Real Estate comply with all Environmental
Laws. Environmental assessments may include detailed visual inspections of such
Real Estate including, without limitation, any and all storage areas, storage
tanks, drains, dry wells and leaching areas, and the taking of soil samples, as
well as such other investigations or analyses as are necessary or appropriate
for a complete determination of the compliance of such Real Estate and the use
and operation thereof with all applicable Environmental Laws. All such
environmental assessments shall be at the sole cost and expense of the
Borrowers.

         Section 8.7. Distributions. The Borrowers shall not make any

quarter and the preceding three (3) fiscal quarters, would exceed ninety
percent (90%) of its Funds from Operations for the four consecutive fiscal
quarters ending prior to the quarter in which such Distribution is paid;

                      (b) In the event that an Event of Default shall have
occurred and be continuing, WDOP shall make no Distributions other than
Distributions to Walden in an amount equal to the minimum Distributions
required under the Code to maintain the REIT Status of Walden, as evidenced by
a certification of the principal financial or accounting officer of Walden
containing calculations in reasonable detail satisfactory in form and substance
to Agent; and

                      (c) In the event that an Event of Default shall have
occurred and be continuing, Walden shall make no Distributions other than the
minimum Distributions required under the Code to maintain the REIT Status of
Walden, as evidenced by a certification of the principal financial or
accounting officer of Walden containing calculations in reasonable detail
satisfactory in form and substance to Agent;

                      (d) Notwithstanding the foregoing, at any time when an
Event of Default shall have occurred and the maturity of the Obligations has
been accelerated, at the option of the Majority Banks, neither Borrower shall
make any Distributions whatsoever, directly or indirectly.

shall sell, transfer or otherwise dispose of any Real Estate or any of the
Unencumbered Operating Properties in excess of $25,000,000.00 (except as the
result of a condemnation or casualty and except for the granting of Permitted
Liens, as applicable) unless there shall have been delivered to the Banks a

thereof shall engage, directly or indirectly, in the development of properties

are hereby expressly waived by the Borrowers; provided that in the event of any
Event of Default specified in Section 12.1(h), Section 12.1(i) or Section

                       (b) Notwithstanding the provisions of subsections (d)
and (e) of Section 12.1, the cure periods provided therein shall not be allowed
and the occurrence of a Default thereunder immediately shall constitute an
Event of Default for all purposes of this Agreement and the other Loan
Documents if, within the period of twelve months immediately preceding the
occurrence of such Default, there shall have occurred two periods of cure or
portions thereof under any one or more than one of said subsections.

         Section 12.2. Termination of Commitments. If any one or more Events of

Bank any unused portion of the credit hereunder shall terminate and the Banks
shall be relieved of all obligations to make Loans to the Borrowers. If any
other Event of Default shall have occurred, the Agent, upon the election of the
Majority Banks, may by notice to the Borrowers terminate the obligation to make
Loans to the Borrowers. No termination under this Section 12.2 shall relieve
the Borrowers of their obligations to the Banks arising under this Agreement or
the other Loan Documents.

         Section 12.3. Remedies. In case any one or more of the Events of
Default shall have occurred and be continuing, and whether or not the Banks
shall have accelerated the maturity of the Loans pursuant to Section 12.1, the
Agent on behalf of the Banks, may, with the consent of the Majority Banks but
not otherwise, proceed to protect and enforce their rights and remedies under
this Agreement, the Notes or any of the other Loan Documents by suit in equity,
action at law or other appropriate proceeding, whether for the specific
performance of any covenant or agreement contained in this Agreement and the
other Loan Documents or any instrument pursuant to which the Obligations are
evidenced, including to the full extent permitted by applicable law the
obtaining of the ex parte appointment of a receiver, and, if such amount shall
have become due, by declaration or otherwise, proceed to enforce the payment
thereof or any other legal or equitable right. No remedy herein conferred upon
the Agent or the holder of any Note is intended to be exclusive of any other
remedy and each and every remedy shall be cumulative and shall be in addition
to every other remedy given hereunder or now or hereafter existing at law or in
equity or by statute or any other provision of law. In the event that all or
any portion of the Obligations is collected by or through an attorney-at-law,
the Borrowers shall pay all costs of collection including, but not limited to,
reasonable attorney's fees not to exceed fifteen percent (15%) of such portion
of the Obligations.

         Section 12.4. Distribution of Proceeds. In the event that, following
the occurrence or during the continuance of any Event of Default, any monies
are received in connection with the enforcement of any of the Loan Documents,
or otherwise with respect to the realization upon any of the assets of the
Borrowers or any other Person liable with respect to the Obligations
(including, without limitation, any Collateral), such monies shall be
distributed for application as follows:

                     (a) First, to the payment of, or (as the case may be) the
reimbursement of, the Agent for or in respect of all reasonable costs,
expenses, disbursements and losses which shall have been incurred or sustained
by the Agent to protect or preserve any collateral or in connection with the
collection of such monies by the Agent, for the exercise, protection or
enforcement by the Agent of all or any of the rights, remedies, powers and
privileges of the Agent under this Agreement or any of the other Loan Documents
or in respect of any collateral or in support of any provision of adequate
indemnity to the Agent against any taxes or liens which by law shall have, or
may have, priority over the rights of the Agent to such monies;

                     (b) Second, to all other Obligations in such order or
preference as the Majority Banks shall determine; provided, however, that (i)
Swing Loans shall be repaid first, (ii) distributions in respect of such other
Obligations shall be made pari passu among Obligations with respect to the
Agent's fee payable pursuant to Section 4.3 and all other Obligations, (iii) in
the event that any Bank shall have wrongfully failed or refused to make an
advance under Section 2.7 and such failure or refusal shall be continuing,
advances made by other Banks during the pendency of such failure or refusal
shall be entitled to be repaid as to principal and accrued interest in priority
to the other Obligations described in this subsection (b), and (iv) Obligations
owing to the Banks with respect to each type of Obligation such as interest,
principal, fees and expenses (but excluding Swing Loans), shall be made among
the Banks pro rata; and provided, further that the Majority Banks may in their
discretion make proper allowance to take into account any Obligations not then
due and payable; and

                     (c) Third, the excess, if any, shall be returned to the
Borrowers or to such other Persons as are entitled thereto.

         Section 13. SETOFF.

         Regardless of the adequacy of any collateral, during the continuance
of any Event of Default, any deposits (general or specific, time or demand,
provisional or final, regardless of currency, maturity, or the branch of where
such deposits are held) or other sums credited by or due from any of the Banks
to the Borrowers or the Guarantors and any securities or other property of the
Borrowers or the Guarantors in the possession of such Bank may be applied to or
set off against the payment of Obligations of such Person and any and all other
liabilities, direct, or indirect, absolute or contingent, due or to become due,
now existing or hereafter arising, of such Person to such Bank. Each of the
Banks agrees with each other Bank that if such Bank shall receive from any of
the Borrowers or the Guarantors, whether by voluntary payment, exercise of the
right of setoff, or otherwise, and shall retain and apply to the payment of the
Note or Notes held by such Bank (but excluding the Swing Loan Note) any amount
in excess of its ratable portion of the payments received by all of the Banks
with respect to the Notes held by all of the Banks, such Bank will make such
disposition and arrangements with the other Banks with respect to such excess,
either by way of distribution, pro tanto assignment of claims, subrogation or
otherwise as shall result in each Bank receiving in respect of the Notes held
by it its proportionate payment as contemplated by this Agreement; provided
that if all or any part of such excess payment is thereafter recovered from
such Bank, such disposition and arrangements shall be rescinded and the amount
restored to the extent of such recovery, but without interest.

         Section 14. THE AGENT.

         Section 14.1. Authorization. The Agent is authorized to take such
action on behalf of each of the Banks and to exercise all such powers as are
hereunder and under any of the other Loan Documents and any related documents
delegated to the Agent, together with such powers as are reasonably incident
thereto, provided that no duties or responsibilities not expressly assumed
herein or therein shall be implied to have been assumed by the Agent. The
obligations of Agent hereunder are primarily administrative in nature, and
nothing contained in this Agreement, the Escrowed Security Documents or any of
the other Loan Documents shall be construed to constitute the Agent as a
trustee for any Bank or to create an agency or fiduciary relationship. The
Borrowers and any other Person shall be entitled to conclusively rely on a
statement from the Agent that it has the authority to act for and bind the
Banks pursuant to this Agreement and the other Loan Documents.

         Section 14.2. Employees and Agents. The Agent may exercise its powers
and execute its duties by or through employees or agents and shall be entitled
to take, and to rely on, advice of counsel concerning all matters pertaining to
its rights and duties under this Agreement and the other Loan Documents. The
Agent may utilize the services of such Persons as the Agent may reasonably
determine, and all reasonable fees and expenses of any such Persons shall be
paid by the Borrowers.

         Section 14.3. No Liability. Neither the Agent nor any of its
shareholders, directors, officers or employees nor any other Person assisting
them in their duties nor any agent, or employee thereof, shall be liable to any
of the Banks for any waiver, consent or approval given or any action taken, or
omitted to be taken, in good faith by it or them hereunder or under any of the
other Loan Documents, or in connection herewith or therewith, or be responsible
for the consequences of any oversight or error of judgment whatsoever, except
that the Agent or such other Person, as the case may be, may be liable for
losses due to its willful misconduct or gross negligence.

         Section 14.4. No Representations. The Agent shall not be responsible
for the execution or validity or enforceability of this Agreement, the Notes,
the Escrowed Security Documents, any of the other Loan Documents or any
instrument at any time constituting, or intended to constitute, collateral
security for the Notes, or for the value of any such collateral security or for
the validity, enforceability or collectability of any such amounts owing with
respect to the Notes, or for any recitals or statements, warranties or
representations made herein, in the Escrowed Security Documents or any
agreement, instrument or certificate delivered in connection therewith or in
any of the other Loan Documents or in any certificate or instrument hereafter
furnished to it by or on behalf of the Borrowers or the Guarantors or any of
their respective Subsidiaries, or be bound to ascertain or inquire as to the
performance or observance of any of the terms, conditions, covenants or
agreements herein, in the Escrowed Security Documents or any agreement,
instrument or certificate delivered in connection therewith or in any other of
the Loan Documents. The Agent shall not be bound to ascertain whether any
notice, consent, waiver or request delivered to it by the Borrowers or the
Guarantors or any holder of any of the Notes shall have been duly authorized or
is true, accurate and complete. The Agent has not made nor does it 


                                     -65-
<PAGE>   67

now make any representations or warranties, express or implied, nor does it
assume any liability to the Banks, with respect to the creditworthiness or
financial condition of the Borrowers, their respective partners, the Guarantors
or any of their respective Subsidiaries. Each Bank acknowledges that it has,
independently and without reliance upon the Agent or any other Bank, and based
upon such information and documents as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement. Each Bank also
acknowledges that it will, independently and without reliance upon the Agent or
any other Bank, based upon such information and documents as it deems
appropriate at the time, continue to make its own credit analysis and decisions
in taking or not taking action under this Agreement and the other Loan
Documents.

         Section 14.5. Payments.

                       (a) A payment by the Borrowers or the Guarantors to the
Agent hereunder or under any of the other Loan Documents for the account of any
Bank shall constitute a payment to such Bank. The Agent agrees to distribute to
each Bank not later than one Business Day after the Agent's receipt of good
funds, determined in accordance with the Agent's customary practices, such
Bank's pro rata share of payments received by the Agent for the account of the
Banks except as otherwise expressly provided herein or in any of the other Loan
Documents.

                       (b) If in the opinion of the Agent the distribution of
any amount received by it in such capacity hereunder, under the Notes or under
any of the other Loan Documents might involve it in liability, it may refrain
from making distribution until its right to make distribution shall have been
adjudicated by a court of competent jurisdiction. If a court of competent
jurisdiction shall adjudge that any amount received and distributed by the
Agent is to be repaid, each Person to whom any such distribution shall have
been made shall either repay to the Agent its proportionate share of the amount
so adjudged to be repaid or shall pay over the same in such manner and to such
Persons as shall be determined by such court.

                       (c) Notwithstanding anything to the contrary contained in
this Agreement or any of the other Loan Documents, any Bank that fails (i) to
make available to the Agent its pro rata share of any Loan or (ii) to comply
with the provisions of Section 13 with respect to making dispositions and
arrangements with the other Banks, where such Bank's share of any payment
received, whether by setoff or otherwise, is in excess of its pro rata share of
such payments due and payable to all of the Banks, in each case as, when and to
the full extent required by the provisions of this Agreement, shall be deemed
delinquent (a "Delinquent Bank") and shall be deemed a Delinquent Bank until
such time as such delinquency is satisfied. A Delinquent Bank shall be deemed
to have assigned any and all payments due to it from the Borrowers and the
Guarantors, whether on account of outstanding Loans, interest, fees or
otherwise, to the remaining nondelinquent Banks for application to, and
reduction of, their respective pro rata shares of all outstanding Loans. The
Delinquent Bank hereby authorizes the Agent to distribute such payments to the
nondelinquent Banks in proportion to their respective pro rata shares of all
outstanding Loans. A Delinquent Bank shall be deemed to have satisfied in full
a delinquency when and if, as a result of application of the assigned payments
to all outstanding Loans of the nondelinquent Banks or as a result of other
payments by the Delinquent Banks to the 


                                     -66-
<PAGE>   68

nondelinquent Banks, the Banks' respective pro rata shares of all outstanding
Loans have returned to those in effect immediately prior to such delinquency
and without giving effect to the nonpayment causing such delinquency.

         Section 14.6. Holders of Notes. Subject to the terms of Article 18,
the Agent may deem and treat the payee of any Note as the absolute owner or
purchaser thereof for all purposes hereof until it shall have been furnished in
writing with a different name by such payee or by a subsequent holder, assignee
or transferee.

         Section 14.7. Indemnity. The Banks ratably agree hereby to indemnify
and hold harmless the Agent from and against any and all claims, actions and
suits (whether groundless or otherwise), losses, damages, costs, expenses
(including any expenses for which the Agent has not been reimbursed by the
Borrowers as required by Section 15), and liabilities of every nature and
character arising out of or related to this Agreement, the Notes, the Escrowed
Security Documents, or any of the other Loan Documents or the transactions
contemplated or evidenced hereby or thereby, or the Agent's actions taken
hereunder or thereunder, except to the extent that any of the same shall be
directly caused by the Agent's willful misconduct or gross negligence.

         Section 14.8. Agent as Bank. In its individual capacity, BKB shall
have the same obligations and the same rights, powers and privileges in respect
to its Commitment and the Loans made by it, and as the holder of any of the
Notes as it would have were it not also the Agent.

         Section 14.9. Resignation. The Agent may resign at any time by giving
60 days' prior written notice thereof to the Banks and the Borrowers. Upon any
such resignation, the Majority Banks shall have the right to appoint as a
successor Agent any Bank or any other bank whose senior debt obligations are
rated not less than "A" or its equivalent by Moody's Investors Service, Inc. or
not less than "A" or its equivalent by Standard & Poor's corporation and which
has a net worth of not less than $500,000,000. Unless a Default or Event of
Default shall have occurred and be continuing, such successor Agent shall be
reasonably acceptable to the Borrowers. If no successor Agent shall have been
so appointed by the Majority Banks and shall have accepted such appointment
within 30 days after the retiring Agent's giving of notice of resignation, then
the retiring Agent may, on behalf of the Banks, appoint a successor Agent,
which shall be any Bank or a bank whose debt obligations are rated not less
than "A" or its equivalent by Moody's Investors Service, Inc. or not less than
"A" or its equivalent by Standard & Poor's Corporation and which has a net
worth of not less than $500,000,000. Upon the acceptance of any appointment as
Agent hereunder by a successor Agent, such successor Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Agent, and the retiring Agent shall be discharged from its
duties and obligations hereunder as Agent. After any retiring Agent's
resignation, the provisions of this Agreement and the other Loan Documents
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 Agent. Upon any change in the
Agent under this Agreement, the resigning Agent shall execute such assignments
of and amendments to the Loan Documents or the Escrowed Security Documents, as
applicable, as may be necessary to substitute the successor Agent for the
resigning Agent.


                                     -67-
<PAGE>   69

         Section 14.10. Duties in the Case of Enforcement. In case one or more
Events of Default have occurred and shall be continuing, and whether or not
acceleration of the Obligations shall have occurred, the Agent shall, if (a) so
requested by the Majority Banks and (b) the Banks have provided to the Agent
such additional indemnities and assurances against expenses and liabilities as
the Agent may reasonably request, proceed to exercise all or any legal and
equitable and other rights or remedies as it may have. The Majority Banks may
direct the Agent in writing as to the method and the extent of any such
exercise, the Banks hereby agreeing to indemnify and hold the Agent harmless
from all liabilities incurred in respect of all actions taken or omitted in
accordance with such directions, provided that the Agent need not comply with
any such direction to the extent that the Agent reasonably believes the Agent's
compliance with such direction to be unlawful or commercially unreasonable in
any applicable jurisdiction.

         Section 15. EXPENSES.

         The Borrowers agree to pay (a) the reasonable costs of producing and
reproducing this Agreement, the other Loan Documents and the other agreements
and instruments mentioned herein, (b) any taxes (including any interest and
penalties in respect thereto) payable by the Agent or any of the Banks (other

amounts paid by them in respect of taxes based on income or other taxes

Documents or the Security Documents (as applicable) is located, such
indemnification to be limited to taxes due solely on account of the granting of
Collateral under the Escrowed Security Documents or the Security Documents, as

any other State on account of the payment or incurrence of such tax by such
indemnified party), including any recording, mortgage, documentary or
intangibles taxes in connection with the Escrowed Security Documents and the
other Loan Documents, or other taxes payable on or with respect to the

agreeing to indemnify the Agent and each Bank with respect thereto), (c) all
reasonable internal charges of the Agent (determined in good faith and in
accordance with the Agent's internal policies applicable generally to its
customers) for commercial finance exams and engineering and environmental

any of the Loan Documents against the Borrowers, the General Partner or the
Guarantors or the administration thereof after the occurrence of a Default or
Event of Default and (ii) any litigation, proceeding or dispute whether arising
hereunder or otherwise, in any way related to the Agent's or any of the Bank's
relationship with the Borrowers, the General Partner or the Guarantors, (g) all
reasonable fees, expenses and disbursements of any Bank or the Agent incurred
in connection with UCC searches, UCC filings, title rundowns or title searches,

attorney's fees and costs) of BKB in connection with the syndication of
interests in the Loans. The covenants of this Section 15 shall survive payment
or satisfaction of payment of amounts owing with respect to the Notes.

         Section 16. INDEMNIFICATION.

         The Borrowers agree to indemnify and hold harmless the Agent and the
Banks and each director, officer, employee, agent and Person who controls the
Agent or any Bank from and against any and all claims, actions and suits,
whether groundless or otherwise, and from and against any and all liabilities,

their respective Subsidiaries, (e) the Borrowers and the Guarantors entering

limited to claims with respect to wrongful death, personal injury or damage to

disbursements of counsel and allocated costs of internal counsel incurred in
connection with any such investigation, litigation or other proceeding;
provided, however, that the Borrowers shall not be obligated under this Section
16 to indemnify any Person for liabilities arising from such Person's own gross
negligence or willful misconduct. In litigation, or the preparation therefor,
the Banks and the Agent shall be entitled to select a single law firm as their
own counsel and, in addition to the foregoing indemnity, the Borrowers agree to
pay promptly the reasonable fees and expenses of such counsel. If, and to the
extent that the obligations of the Borrowers under this Section 16 are
unenforceable for any reason, the Borrowers hereby agree to make the maximum
contribution to the payment in satisfaction of such obligations which is
permissible under applicable law. The provisions of this Section 16 shall
survive the repayment of the Loans and the termination of the obligations of
the Banks hereunder.

in the Notes, in any of the other Loan Documents or in any documents or other
papers delivered by or on behalf of the Borrowers, the General Partner, the
Guarantors or any of their respective Subsidiaries pursuant hereto or thereto

notwithstanding any investigation heretofore or hereafter made by any of them,
and shall survive the making by the Banks of any of the Loans, as herein
contemplated, and shall continue in full force and effect so long as any amount
due under this Agreement or the Notes or any of the other Loan Documents

indemnification obligations of the Borrowers provided herein and the other Loan
Documents shall survive the full repayment of amounts due and the termination
of the obligations of the Banks hereunder and thereunder to the extent provided
herein and therein. All statements contained in any certificate or other paper
delivered to any Bank or the Agent at any time by or on behalf of the
Borrowers, the General Partner, the Guarantors or any of their respective
Subsidiaries pursuant hereto or in connection with the transactions
contemplated hereby shall constitute representations and warranties by such
Person hereunder.

         Section 18. ASSIGNMENT AND PARTICIPATION.

         Section 18.1. Conditions to Assignment by Banks. Except as provided

portion of its interests, rights and obligations under this Agreement
(including all or a portion of its Commitment Percentage and Commitment and the
same portion of the Loans at the time owing to it, and the Notes held by it);
provided that (a) the Agent shall have given its prior written consent to such
assignment, which consent shall not be unreasonably withheld or delayed
(provided that such consent shall not be required for any assignment to another
Bank, to a bank which is under common control with the assigning Bank or to a
wholly-owned Subsidiary of such Bank provided that such assignee shall remain a
wholly-owned Subsidiary of such Bank), (b) each such assignment shall be of a
constant, and not a varying, percentage of all the assigning Bank's rights and
obligations under this Agreement, (c) the parties to such assignment shall
execute and deliver to the Agent, for recording in the Register (as hereinafter
defined), a notice of such assignment, together with any Notes subject to such
assignment, (d) in no event shall any voting, consent or approval rights of a
Bank be assigned to any Person controlling, controlled by or under common

Borrowers, the General Partner or the Guarantors which rights shall instead be
allocated pro rata among the other remaining Banks, (e) such assignee shall
have a net worth as of the date of such assignment of not less than
$500,000,000, and (f) such assignee shall acquire an interest in the Loans of
not less than $10,000,000. Upon such execution, delivery, acceptance and
recording, of such notice of assignment, (i) the assignee thereunder shall be a
party hereto and all other Loan Documents executed by the Banks and, to the
extent provided in such assignment, have the rights and obligations of a Bank
hereunder, (ii) the assigning Bank shall, to the extent provided in such
assignment and upon payment to the Agent of the registration fee referred to in
Section 18.2, be released from its obligations under this Agreement, and (iii)
the Agent may unilaterally amend Schedule 1 to reflect such assignment. In
connection with each assignment, the assignee shall represent and warrant to
the Agent, the


                                     -70-
<PAGE>   72

assignor and each other Bank as to whether such assignee is controlling,
controlled by, under common control with or is not otherwise free from
influence or control by, the Borrowers, the General Partner and the Guarantors.

         Section 18.2. Register. The Agent shall maintain a copy of each
assignment delivered to it and a register or similar list (the "Register") for
the recordation of the names and addresses of the Banks and the Commitment
Percentages of, and principal amount of the Loans owing to the Banks from time
to time. The entries in the Register shall be conclusive, in the absence of
manifest error, and the Borrowers, the Agent and the Banks may treat each
Person whose name is recorded in the Register as a Bank hereunder for all
purposes of this Agreement. The Register shall be available for inspection by
the Borrowers and the Banks at any reasonable time and from time to time upon
reasonable prior notice. Upon each such recordation, the assigning Bank agrees
to pay to the Agent a registration fee in the sum of $2,000.

         Section 18.3. New Notes. Upon its receipt of an assignment executed by
the parties to such assignment, together with each Note subject to such
assignment, the Agent shall (a) record the information contained therein in the
Register, and (b) give prompt notice thereof to the Borrowers and the Banks
(other than the assigning Bank). Within five Business Days after receipt of
such notice, the Borrowers, at their own expense, shall execute and deliver to
the Agent, in exchange for each surrendered Note, a new Note to the order of
such assignee in an amount equal to the amount assumed by such assignee
pursuant to such assignment and, if the assigning Bank has retained some
portion of its obligations hereunder, a new Note to the order of the assigning
Bank in an amount equal to the amount retained by it hereunder, and shall cause
the Guarantors to deliver to the Agent an acknowledgment in form and substance
satisfactory to the Agent to the effect that the Guaranty extends to and is
applicable to each new Note. Such new Notes shall provide that they are
replacements for the surrendered Notes, shall be in an aggregate principal
amount equal to the aggregate principal amount of the surrendered Notes, shall
be dated the effective date of such assignment and shall otherwise be in
substantially the form of the assigned Notes. The surrendered Notes shall be
canceled and returned to the Borrowers.

         Section 18.4. Participations. Each Bank may sell participations to one
or more banks or other entities in all or a portion of such Bank's rights and
obligations under this Agreement and the other Loan Documents; provided that
(a) any such sale or participation shall not affect the rights and duties of
the selling Bank hereunder to the Borrowers, (b) such sale and participation
shall not entitle such participant to any rights or privileges under this
Agreement or the Loan Documents (including, without limitation, the right to
approve waivers, amendments or modifications), (c) such participant shall have
no direct rights against the Borrowers or the Guarantors except the rights
granted to the Banks pursuant to Section 13, (d) such sale is effected in
accordance with all applicable laws, and (e) such participant shall not be a
Person controlling, controlled by or under common control with, or which is not
otherwise free from influence or control by, the Borrowers, the General Partner
or the Guarantors. Any Bank which sells a participation shall promptly notify
the Agent of such sale and the identity of the purchaser of such interest.

any portion of its interest and rights under this Agreement (including all or
any portion of its Note) to any of the twelve Federal Reserve Banks organized

right to specify as its address any other address within the United States of

partners, joint venturers or any other relationship other than lender and
borrower.

<PAGE>   75

AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS MAY BE BROUGHT IN THE COURTS OF
THE COMMONWEALTH OF MASSACHUSETTS OR ANY FEDERAL COURT SITTING THEREIN AND

against whom enforcement is sought.

         EACH OF THE BORROWERS, THE AGENT AND THE BANKS HEREBY WAIVES ITS RIGHT
TO A JURY TRIAL WITH RESPECT TO ANY ACTION OR CLAIM ARISING OUT OF ANY DISPUTE
IN CONNECTION WITH THIS AGREEMENT, ANY NOTE OR ANY OF THE OTHER LOAN DOCUMENTS,
ANY RIGHTS OR OBLIGATIONS HEREUNDER OR THEREUNDER OR THE PERFORMANCE OF SUCH
RIGHTS AND OBLIGATIONS. EXCEPT TO THE EXTENT EXPRESSLY PROHIBITED BY LAW, THE
BORROWERS HEREBY WAIVE ANY RIGHT EITHER OF THEM MAY HAVE TO CLAIM OR RECOVER IN
ANY SUCH LITIGATION ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES
OR ANY DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES. THE BORROWERS (A)
CERTIFY THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY BANK OR THE AGENT HAS
REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH BANK OR THE 


                                     -74-
<PAGE>   76

AGENT WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING

TO THE FOREGOING AS ITS FREE, KNOWING AND VOLUNTARY ACT.

         Section 26. DEALINGS WITH THE BORROWERS.

         The Banks and their affiliates may accept deposits from, extend credit
to and generally engage in any kind of banking, trust or other business with
either Borrower, the Guarantors, their respective Subsidiaries or any of their
affiliates regardless of the capacity of the Bank hereunder.

         Section 27. CONSENTS, AMENDMENTS, WAIVERS, ETC.

         Except as otherwise expressly provided in this Agreement, any consent
or approval required or permitted by this Agreement may be given, and any term
of this Agreement or of any other instrument related hereto or mentioned herein
may be amended, and the performance or observance by the Borrowers of any terms
of this Agreement or such other instrument or the continuance of any Default or
Event of Default may be waived (either generally or in a particular instance
and either retroactively or prospectively) with, but only with, the written
consent of the Majority Banks. Notwithstanding the foregoing, none of the
following may occur without the written consent of each Bank: a change in the
rate of interest on and the term of the Notes; a change in the amount of the
Commitments of the Banks; a forgiveness, reduction or waiver of the principal
of any unpaid Loan or any interest thereon or fee payable under the Loan
Documents; a change in the amount of any fee payable to a Bank hereunder; the
postponement of any date fixed for any payment of principal of or interest on
the Loan; an extension of the Maturity Date; a change in the manner of
distribution of any payments to the Banks or the Agent; the release of a
Borrower or a Guarantor or any Collateral except as otherwise provided herein;
an amendment of the definition of Majority Banks or of any requirement for
consent by all of the Banks; any modification to require a Bank to fund a pro
rata share of a request for an advance of the Loan made by the Borrowers other
than based on its Commitment Percentage; an amendment to Section 9.1; an
amendment to this Section 27; an amendment of the definition of Majority Banks;
or an amendment of any provision of this Agreement or the Loan Documents which
requires the approval of all of the Banks or the Majority Banks to require a
lesser number of Banks to approve such action. The amount of the Agent's fee
payable for the Agent's account and the provisions of Section 14 may not be
amended without the written consent of the Agent. There shall be no amendment,
modification or waiver of any provision in the Loan Documents with respect to
Swing Loans without the consent of the Swing Loan Bank. No waiver shall extend
to or affect any obligation not expressly waived or impair any right consequent
thereon. No course of dealing or delay or omission on the part of the Agent or
any Bank in exercising any right shall 


                                     -75-
<PAGE>   77

operate as a waiver thereof or otherwise be prejudicial thereto. No notice to
or demand upon the Borrowers shall entitle the Borrowers to other or further
notice or demand in similar or other circumstances.

         Section 28. SEVERABILITY.

         The provisions of this Agreement are severable, and if any one clause
or provision hereof shall be held invalid or unenforceable in whole or in part
in any jurisdiction, then such invalidity or unenforceability shall affect only
such clause or provision, or part thereof, in such jurisdiction, and shall not
in any manner affect such clause or provision in any other jurisdiction, or any
other clause or provision of this Agreement in any jurisdiction.

         Section 29. TIME OF THE ESSENCE.

         Time is of the essence with respect to each and every covenant,
agreement and obligation of the Borrowers under this Agreement and the other
Loan Documents.

         Section 30. NO UNWRITTEN AGREEMENTS.

         THE WRITTEN LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE
PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR
SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL
AGREEMENTS BETWEEN THE PARTIES.

         Section 31. REPLACEMENT OF NOTES.

         Upon receipt of evidence reasonably satisfactory to the Borrowers of
the loss, theft, destruction or mutilation of any Note, and in the case of any
such loss, theft or destruction, upon delivery of an indemnity agreement
reasonably satisfactory to the Borrowers or, in the case of any such
mutilation, upon surrender and cancellation of the applicable Note, the
Borrowers will execute and deliver, in lieu thereof, a replacement Note,
identical in form and substance to the applicable Note and dated as of the date
of the applicable Note and upon such execution and delivery all references in
the Loan Documents to such Note shall be deemed to refer to such replacement
Note.

         Section 32. JOINT AND SEVERAL LIABILITY.

         Each of the Borrowers covenants and agrees that each and every
covenant and obligation of any Borrower hereunder and under the other Loan
Documents shall be the joint and several obligations of each Borrower.

         Section 33.1. Waiver of Automatic or Supplemental Stay. Each of the
Borrowers represent, warrant and covenant to the Banks and Agent that in the
event of the filing of any voluntary or involuntary petition in bankruptcy by
or against the other of the Borrowers at any time following the execution and
delivery of this Agreement, neither of the Borrowers shall seek a supplemental
stay or any other relief, whether injunctive or otherwise, pursuant to Section
105 of the Bankruptcy Code or any other provision of the Bankruptcy Code, to
stay, interdict, condition, reduce or inhibit the ability of the Banks or Agent
to enforce any rights it has by virtue of this Agreement, the Loan Documents,
or at law or in equity, or any other rights the Banks or Agent has, whether now
or hereafter acquired, against the other Borrower or against any property owned
by such other Borrower.

                       (e) any failure on the part of the Banks or Agent to

other rights with respect thereto, or the liability of any party liable for the
Loan Documents or the obligations evidenced or secured thereby, or any failure
on the part of the Banks or Agent to disclose to the Borrowers any facts any of
them may now or hereafter know regarding the Borrowers, any Guarantors, their
respective assets, or such other parties, whether such facts materially
increase the risks to Borrowers or not;

equitable or surety defenses whatsoever to which a Borrower might otherwise be
entitled

         Section 33.3. Waiver. Each of the Borrowers waives, to the fullest
extent that each may lawfully so do, the benefit of all appraisement,
valuation, stay, extension, homestead, exemption and redemption laws which such
Person may claim or seek to take advantage of in order to prevent or hinder the
enforcement of any of the Loan Documents or the exercise by Banks or Agent of
any of their respective remedies under the Loan Documents and, to the fullest
extent that the Borrowers may lawfully so do, such Person waives any and all
right to have the assets of such Person marshaled upon any exercise of remedies
hereunder. Each of the Borrowers further agrees that the Banks and Agent shall
be entitled to exercise their respective rights and remedies under the Loan
Documents or at law or in equity in such order as they may elect. Without
limiting the foregoing, each of the Borrowers further agrees that upon the
occurrence of an Event of Default, the Banks and Agent may exercise any of such
rights and remedies without notice to either of the Borrowers except as
required by law or the Loan Documents and agrees that neither the Banks nor
Agent shall be required to proceed against the other of the Borrowers, any
Guarantor or any other Person or to proceed against or to exhaust any other
security held by the Banks or Agent at any time or to pursue any other remedy
in Bank's or Agent's power or under any of the Loan Documents before proceeding
against a Borrower or its assets under the Loan Documents.

         Section 33.4. Subordination. Each of the Borrowers hereby expressly
waives any right of contribution from or indemnity against the other, whether
at law or in equity, arising from any payments made by such Person pursuant to
the terms of this Agreement or the Loan Documents, and each of the Borrowers
acknowledges that it has no right whatsoever to proceed against the other for
reimbursement of any such payments. In connection with the foregoing, each of
the Borrowers expressly waives any and all rights of subrogation to the Banks
or Agent against the other of the Borrowers, and each of the Borrowers hereby
waives any rights to enforce any remedy which the Banks or Agent may have
against the other of the Borrowers and any rights to participate in any
collateral or any other assets of the other Borrower. In addition to and
without in any way limiting the foregoing, each of the Borrowers hereby
subordinates any and all indebtedness it may now or hereafter owe to such other
Borrower to all indebtedness of the 


                                     -79-
<PAGE>   81

Borrowers to the Banks and Agent, and agrees with the Banks and Agent that
neither of the Borrowers shall claim any offset or other reduction of such
Borrower's obligations hereunder because of any such indebtedness and shall not
take any action to obtain any collateral or any other assets of the other
Borrower.

$______________                                       As of December ___ , 1998


         FOR VALUE RECEIVED, the undersigned WALDEN/DREVER OPERATING
PARTNERSHIP, L.P., a Delaware limited partnership, and WALDEN RESIDENTIAL
PROPERTIES, INC., a Maryland corporation, hereby jointly and severally promise
to pay to ______________________________ or order, in accordance with the terms
of that certain First Amended and Restated Revolving Credit Agreement dated as
of December 18, 1998 (the "Credit Agreement"), as from time to time in effect,
among the undersigned, BankBoston, N.A., for itself and as Agent, and such
other Banks as may be from time to time named therein, to the extent not sooner
paid, on or before the Maturity Date the principal sum of _____________________
__________________________________ DOLLARS ($______________), or such amount as
may be advanced by the payee hereof under the Credit Agreement (but excluding
Swing Loans made pursuant to Section Section 2.4A(a) through (c) of the Credit
Agreement) with daily interest from the date hereof, computed as provided in
the Credit Agreement, on the principal amount hereof from time to time unpaid,
at a rate per annum on each portion of the principal amount which shall at all
times be equal to the rate of interest applicable to such portion in accordance
with the Credit Agreement, and with interest on overdue principal and, to the
extent permitted by applicable law, on overdue installments of interest and
late charges at the rates provided in the Credit Agreement. Interest shall be
payable on the dates specified in the Credit Agreement, except that all accrued
interest shall be paid at the stated or accelerated maturity hereof or upon the
prepayment in full hereof. Capitalized terms used herein and not otherwise
defined herein shall have the meanings set forth in the Credit Agreement.

         Payments hereunder shall be made to BankBoston, N.A., as Agent for the
payee hereof, 100 Federal Street, Boston, Massachusetts 02110.

         This Note is one of one or more Notes evidencing borrowings under and
is entitled to the benefits and subject to the provisions of the Credit
Agreement. The principal of this Note may be due and payable in whole or in
part prior to the maturity date stated above and is subject to mandatory
prepayment in the amounts and under the circumstances set forth in the Credit
Agreement, and may be prepaid in whole or from time to time in part, all as set
forth in the Credit Agreement.

         Notwithstanding anything in this Note to the contrary, all agreements
between the Borrowers and the Banks and the Agent, whether now existing or
hereafter arising and whether written or oral, are hereby limited so that in no
contingency, whether by reason of acceleration of the maturity of any of the
Obligations or otherwise, shall the interest contracted for, charged or
received by the Banks exceed the maximum amount permissible under applicable
law. If, from any circumstance whatsoever, interest would otherwise be payable
to the Banks in excess of the maximum lawful amount, the interest payable to 
the Banks shall be reduced to the maximum 

<PAGE>   95

amount permitted under applicable law; and if from any circumstance the Banks
shall ever receive anything of value deemed interest by applicable law in
excess of the maximum lawful amount, an amount equal to any excessive interest
shall be applied to the reduction of the principal balance of the Obligations
and to the payment of interest or, if such excessive interest exceeds the
unpaid balance of principal of the Obligations, such excess shall be refunded
to the Borrowers. All interest paid or agreed to be paid to the Banks shall, to
the extent permitted by applicable law, be amortized, prorated, allocated and
spread throughout the full period until payment in full of the principal of the
Obligations (including the period of any renewal or extension thereof) so that
the interest thereon for such full period shall not exceed the maximum amount
permitted by applicable law. This paragraph shall control all agreements
between the Borrowers and the Banks and the Agent.

         In case an Event of Default shall occur, the entire principal amount
of this Note may become or be declared due and payable in the manner and with
the effect provided in said Credit Agreement.

         This Note shall be governed by and construed in accordance with the
laws of the Commonwealth of Massachusetts (without giving effect to the
conflict of laws rules of any jurisdiction).

         The undersigned makers and all guarantors and endorsers, hereby waive
presentment, demand, notice, protest, notice of intention to accelerate the
indebtedness evidenced hereby, notice of acceleration of the indebtedness
evidenced hereby and all other demands and notices in connection with the
delivery, acceptance, performance and enforcement of this Note, except as
specifically otherwise provided in the Credit Agreement, and assent to
extensions of time of payment or forbearance or other indulgence without
notice.

officer or partner executed this Note under seal as of the day and year first
above written.
