                6.3.  CASH MANAGEMENT.

                      (a)  Collection Account. For so long as any obligations of
                           Borrower to Lender remain outstanding under the Loan
                           Agreement, Borrower agrees as follows:

                           (i)  Borrower shall open and maintain a lockbox

                          (iii) Borrower may designate a new financial
institution to serve as the Collection Account Bank if approved by Agent in
Agent's reasonable discretion. If the Collection Account Bank resigns pursuant
to the terms of the Collection Account Agreement, Borrower shall replace such
Collection Account Bank with a bank and documentation acceptable to Agent prior
to the date that such resignation becomes effective.

                  (b)     Payments. Prior to the occurrence of a Cash Management
Event, Borrower shall make all payments due under this Agreement and any other
Loan Document from an account of Borrower. After the occurrence of a Cash
Management Event, pursuant to the Collection Account Agreement among the
Collection Account Bank, Borrower and Agent (the "Collection Account
Agreement"), the Collection Account Bank will be authorized and directed to (a)
transfer on a daily basis all funds deposited in the Collection Account to Agent
or Agent's designee to be held in an Eligible Account established by Agent or
Agent's designee (the "Cash Collateral Account"), as directed by Agent, and (b)
take directions only from Agent (and not from Borrower) as to the withdrawal and
disbursement of funds in the Cash Collateral Account and and funds in the
Collection Account. Notwithstanding the foregoing, in the event funds in the
Collection Account are being transferred to the Cash Collateral Account on the
date which is 6 months after the cure of the event which triggered the Cash
Management Event and provided no Cash Management Event exists on such date, as
determined by Agent in its sole discretion, at Agent's direction, such funds
shall no longer be transferred to the Cash Collateral Account and shall be
transferred in accordance with the last sentence of subsection (a)(ii) above
until a Cash Management Event again occurs, in which event the funds in the
Collection Account shall be transferred to the Cash Collateral Account. The Cash
Collateral Account shall be under the sole dominion and control of Agent.
Borrower, each Joint Venture, and Alterra, as manager, shall have no right of
withdrawal from the Cash Collateral Account.

                  (c)     Establishment of Sub-Accounts. The Cash Collateral
Account shall contain a Property Tax Cost Sub-Account, a Debt Service Payment
Sub-Account and an Operating Expense Sub-Account, each of which Sub-Accounts (i)
may be ledger or book entry accounts and need not be actual accounts
(individually, a "Sub-Account" and collectively, the "Sub-Accounts") and (ii)
shall be an Eligible Account to which certain funds shall be allocated and from
which disbursements shall be made pursuant to the terms of this Loan Agreement.

                  (d)     Interest on Accounts. All interest paid or other
earnings on the funds in the Cash Collateral Account shall be income of Borrower
and shall be deposited into the Cash Collateral Account and shall be subject to
allocation and distribution like any other monies deposited therein.

                  (e)     Payment of Property Tax Costs, Debt Service and
Operating Expenses.

                          (i)   Payment of Property Tax Cost.

                           a. At least five (5) Business Days prior to the Due
Date of any Property Tax Cost payment, Borrower shall notify Agent in writing
and request that Agent make such Property Tax Cost payment on behalf of Borrower
on or prior to the due date thereof. Together with each such request, Borrower
shall furnish Agent with copies of bills and other documentation as may be
reasonably required by Agent to establish that such Property Tax Cost payment is
then due. Agent shall be entitled to conclusively rely on all bills or other
documentation received from Borrower, in each case without independent
investigation or verification. Agent shall make such payments out of the
Property Tax Cost Sub-Account before the same shall be delinquent to the extent
that there are funds available in the Property Tax Cost Sub-Account and Agent
has received appropriate documentation to establish the amounts due and the due
dates as and when provided above.

                           b. Except to the extent that Agent is obligated to
pay Property Tax Cost from the Property Tax Cost Sub-Account pursuant to the
terms of this section, Borrower shall pay all Property Tax Cost with respect to
itself and the Properties in accordance with the provisions of the Mortgages.

                  (ii)     Payment of Debt Service. On the first Business Day of
each month during the term of the Loan, Agent shall transfer to Lenders from the
Debt Service Payment Sub-Account the amount of principal and interest then due
pursuant to the Notes. Borrower shall be deemed to have made timely payment
regardless of the time Agent makes such transfer as long as sufficient funds are
on deposit in the Debt Service Payment Sub-Account at 12:00 noon, New York City
time on the first Business Day of the applicable month.

                  (iii)    Payment of Operating Expenses. Not more frequently
than once each month and provided that Lenders have not accelerated the
Indebtedness due to the occurrence of an Event of Default, Agent shall direct
the Cash Collateral Account Bank to, within five (5) Business Days after Agent's
receipt of an Operating Expense Certificate from Borrower (such Operating
Expense Certificate to be delivered by Borrower not more frequently than once
each month) transfer funds to Borrower or its designee from the Operating
Expense Sub-Account, to the extent that there are funds available therein, in an
amount not to exceed the amount stated in the Operating Expense Certificate up
to the Operating Expense Monthly Installment. Together with each such Operating
Expense Certificate, Borrower shall furnish Agent with an Officer's Certificate
stating that all operating expenses from previous periods have been paid in full
and that all amounts shown on the Operating Expense Certificate are then due or
have been paid.

                  (iv)     Extra Funds for Operating Expenses. Not more
frequently than once each month and provided that Lenders have not accelerated
the Indebtedness due to the occurrence of an Event of Default, if in a given
month Borrower requires amounts in excess of the Operating Expense Monthly
Installment (such excess amounts, "Extra Funds"), Borrower may deliver a written
request to Agent for a disbursement of Extra Funds stating the amount of Extra
Funds and the purpose for such



                                       4
<PAGE>   5

amount, together with copies of bills and other documentation as may be required
by Agent to establish that such additional operating expenses are reasonable and
that such amounts are then due or expected to come due in that month. Agent
shall approve or disapprove such request within ten (10) Business Days after
Agent's receipt of such request and, if approved, Agent shall release the Extra
Funds to Borrower or its designee within ten (10) Business Days after Agent's
approval.

                  (f)     Monthly Funding of Sub-Accounts. During each month of
the term of the Loan, Agent shall allocate all funds then on deposit in the Cash
Collateral Account among the Sub-Accounts as follows and in the following
priority:

                           (i)   first, to the Property Tax Cost Sub-Account,
until an amount equal to the Property Tax Cost Monthly Installment for the
current month has been allocated to the Property Tax Cost Sub-Account;

                           (ii)  second, to the Debt Service Payment
Sub-Account, until an amount equal to the payments due on the Notes on the first
Business Day of the next succeeding month has been allocated to the Debt Service
Payment Sub-Account;

                           (iii) third, to the Operating Expense Sub-Account,
until an amount equal to the Operating Expense Monthly Installment for the
current month has been allocated to the Operating Expense Sub-Account; and

                           (iv)  fourth, provided that (i) no Event of Default
has occurred and is continuing and (ii) Agent has received all financial
information described in Section 5.3 for the most current periods for which the
same are due, Lenders agree that in each month any amounts deposited into or
remaining in the Cash Collateral Account after (A) the minimum amounts set forth
in clauses (i), (ii) and (iii) have been satisfied with respect to the current
month and any periods prior thereto and (B) the funding of additional reserves
at levels determined by Borrower to be prudent for working capital and other
Borrower costs, which level shall be satisfactory to Agent in Agent's reasonable
discretion, shall be disbursed by Agent to such account as Borrower may request
in writing. Agent and Lenders shall not be responsible for monitoring Borrower's
use of any funds disbursed from the Cash Collateral Account or any of the
Sub-Accounts.

                           (v)   if an Event of Default has occurred and is
continuing or if on the date due the balance in any Sub-Account is insufficient
to make the required payment due from such Sub-Account, Agent may, in its sole
discretion, in addition to any other rights and remedies available hereunder,
withdraw funds from any other Sub-Account to pay such deficiency. If Lender
elects to apply funds of any such Sub-Account to pay amounts due under the
Notes, Borrower shall, upon demand, repay to Lenders the amount of such
withdrawn funds to replenish such Sub-Account, and if Borrower shall fail to
repay such amount within three (3) Business Days after notice of such
withdrawal, an Event of Default shall exist hereunder.

                           (g)   Notwithstanding the application of funds from
the Cash Collateral Account as herein provided, for purposes of determining
whether a Property Default has occurred under any Attornment, Subordination and
Non-Disturbance Agreement among Agent, Borrower and a Joint Venture, any
deposits to the Cash Collateral Account constituting Net Cash Flow from the
Project leased to such Joint Venture shall be treated as lease payments under
the applicable JV Lease.

copies, by the parties hereto.

         Section 4.        Governing Law.
