                  (a) The Partnership hereby establishes in the name of Account

held in trust by it for the benefit, and as the property, of Account Bank, for
the benefit of Trustee, and shall not be commingled with any other funds or

                        (5) The funds released to the Partnership pursuant

in Permitted Investments of the type described in clause (viii) of the
definition of Permitted Investments which investment shall be Evergreen 100%
Treasury Fund (the "FUND INVESTMENT") to enable Account Bank, for the benefit of
Trustee, or Trustee to exercise and enforce Trustee's rights and remedies
hereunder with respect to any Collateral.

                  (r) Any amounts held in any of the Accounts shall be invested,
liquidated and reinvested at the Partnership's written direction, in the name of
Account Bank, for the benefit of Trustee, as secured party in Permitted

for purposes of purchasing Permitted Investments. In no event shall Account Bank
or Trustee have any responsibility or liability for the types of investments

confirm that the same are in fact Permitted Investments.

                  (s) All of the Accounts established pursuant to this Agreement

is a segregated trust account or accounts maintained with the corporate trust
department of a federal depository institution or state-chartered depository

it by the Partnership, Trustee or the Servicer. In case of conflict between the
instructions of the Partnership, on the one hand, and Trustee or any Servicer,
on the other, Account Bank will follow instructions of the Trustee or such
Servicer, as the case may be.

            4. FINANCING STATEMENT; FURTHER ASSURANCES. Simultaneously herewith,
the Partnership shall execute and file (and deliver to the Trustee photostatic
confirmation of such filing) a financing statement or statements in connection
with the Collateral in the form required properly to perfect Account Bank's
security interest, for the benefit of Trustee, therein. Account Bank shall be
under no obligation to monitor such filing. At any time and from time to time,
at the expense of the Partnership, the Partnership shall promptly execute and
deliver all further instruments and documents, and take all further action, that
may be necessary or desirable, or that Account Bank or Trustee may reasonably
request, in order to perfect and protect any security interest granted or
purported to be granted hereby (including, without limitation, any security
interest in and to any Permitted Investments) or to enable Account Bank or
Trustee to exercise and enforce its rights and remedies hereunder with respect
to any Collateral.

            5. TRANSFERS AND OTHER LIENS. Each of the Partnership and MAALP
agrees that it will not (i) sell or otherwise dispose of any of the Collateral
except in accordance with this Agreement or (ii) create or permit to exist any

                                      -5-

lien upon or with respect to all or any of the Collateral, except for the lien
of the Indenture, any Mortgage or any other Security Document and the lien
granted to Account Bank, for the benefit of Trustee, under this Agreement.

            6. TRUSTEE'S RIGHT TO PERFORM THE PARTNERSHIP'S OBLIGATIONS; NO
LIABILITY OF TRUSTEE. If the Partnership fails to perform any of the covenants
or obligations contained herein, and such failure shall continue for a period
five (5) Business Days after the Partnership's receipt of written notice thereof
from Trustee, Trustee may itself perform, or cause performance of, such
covenants or obligations, and the reasonable expenses of Trustee and its agents,
if any, incurred in connection therewith shall be payable by the Partnership to
Trustee in accordance with Section 10 hereof. Notwithstanding Trustee's right to
perform certain obligations of the Partnership, it is acknowledged and agreed
that the Partnership retains control of the Premises and operation thereof and
notwithstanding anything contained herein or Account Bank's or Trustee's
exercise of any of its rights or remedies hereunder, under the Notes, the
Indenture or any of the other Security Documents or otherwise at law or in
equity, neither Account Bank nor Trustee shall be deemed to be a
mortgagee-in-possession nor shall Trustee or Account Bank be subject to any
liability with respect to the Premises or otherwise based upon any claim of
trustee liability, except to the extent that any loss or damage results from
Trustee's or Account Bank's gross negligence or willful misconduct.

            7.    REASONABLE CARE.

                  (a) Account Bank shall have no liability or obligation with
respect to the Accounts except for Account Bank's willful misconduct or gross
negligence. Account Bank's sole responsibility shall be for the safekeeping,
investment and disbursement of the Accounts in accordance with the terms of this
Agreement. Account Bank shall have no implied duties or obligations and shall
not be charged with knowledge or notice of any fact or circumstance except as
specifically set forth herein. Account Bank shall not be obligated to take any
legal action or commence any proceeding in connection with the Accounts or this
Agreement.

                  (b) Except for the exercise of reasonable care in the custody
thereof, Trustee shall have no duty as to any Collateral in its possession or
control as agent therefor or bailee thereof or any income thereon or the
preservation of rights against any person or otherwise with respect thereto.
Trustee shall be deemed to have exercised reasonable care in the custody and
preservation of the Collateral in its possession if the Collateral is accorded
treatment substantially equal to that which Trustee accords its own property, it
being understood that Trustee shall not be liable or responsible for any loss or
damage to any of the Collateral, or for any diminution in value thereof, by
reason of the act or omission of Trustee, its Affiliates, agents, employees or
bailees, except to the extent that such loss or damage results from the gross
negligence or willful misconduct of Trustee.

            8. REMEDIES. Upon the occurrence of an Event of Default prior to the
Permitted Merger Date, Account Bank, acting upon the written direction of
Trustee, may:

                                      -9-

                  (a) at any time or from time to time, charge, set off and
      otherwise apply all or any part of the Collateral against the Obligations
      or any part thereof;

                  (b) at any time and from time to time, exercise any and all
      rights and remedies available to it under this Agreement and/or as a
      secured party under the UCC; and

                  (c) demand, collect, take possession of, receipt for, settle,
      compromise, adjust, sue for, foreclose or realize upon the Collateral (or
      any portion thereof) as Trustee may determine in its sole discretion.

            The Partnership hereby expressly waives, to the fullest extent
permitted by law, presentment, demand, protest or any notice of any kind in
connection with this Agreement or the Collateral (except as otherwise provided
herein). The Partnership acknowledges and agrees that ten (10) days' prior
written notice of the time and place of any public sale of the Collateral or any
other intended disposition thereof shall be reasonable and sufficient notice to
the Partnership within the meaning of the UCC.

            9. NO WAIVER. The rights and remedies provided in this Agreement,
the Indenture and the other Security Documents are cumulative and may be
exercised independently or concurrently, and are not exclusive of any other
right or remedy provided at law or in equity. No failure to exercise or delay by
Account Bank or Trustee in exercising any right or remedy hereunder or under the
Indenture or the other Security Documents shall impair or prohibit the exercise
of any such rights or remedies in the future or be deemed to constitute a waiver
or limitation of any such right or remedy or acquiescence therein. Every right
and remedy granted to Account Bank and/or Trustee under Paragraph 8 or by law
may be exercised by Account Bank and/or Trustee at any time and from time to
time, and as often as Account Bank and/or Trustee may deem it expedient. Any and
all of Account Bank's and/or Trustee's rights with respect to the lien and
security interest granted hereunder shall continue unimpaired, and the
Partnership shall be and remain obligated in accordance with the terms hereof,
notwithstanding (a) any proceeding of the Partnership under the Federal
Bankruptcy Code or any bankruptcy, insolvency or reorganization laws or statutes
or any state, (b) the release or substitution of Collateral at any time, or of
any rights or interests therein except for any such release as provided in
Article Nine of the Indenture or (c) any delay, extension of time, renewal,
compromise or other indulgence granted by Account Bank and/or Trustee in the
event of any default with respect to the Collateral or otherwise hereunder or
under the Indenture or the other Security Documents. No delay or extension of
time by Account Bank and/or Trustee in exercising any power of sale, option or
other right or remedy hereunder, and no notice or demand which may be given to
or made upon the Partnership by Account Bank and/or Trustee, shall constitute a
waiver thereof, or limit, impair or prejudice Account Bank's and/or Trustee's
right, without notice or demand (except as herein provided), to take any action
against the Partnership or to exercise any other power of sale, option or any
other right or remedy.

                                      -10-

            10. FEES AND EXPENSES. The Collateral shall secure, and the
Partnership shall pay to Account Bank and Trustee, their respective agents
and/or Account Bank's and Trustee's respective counsel on demand, from time to
time, all reasonable fees, costs and expenses (including, but not limited to,
reasonable attorneys' fees and disbursements, and transfer, recording and filing
fees, taxes and other charges) of, or incidental to, the creation or perfection
of any Lien or security interest granted or intended to be granted hereby, the
custody, care, sale, transfer, administration, investment, reinvestment,
collection of or realization on the Collateral, or in any way relating to the
enforcement, protection or preservation of the rights or remedies of Account
Bank and/or Trustee under this Agreement, the Note, the Mortgage or the other
Security Documents.

            11. ACCOUNT BANK APPOINTED ATTORNEY-IN-FACT. For so long as no Event
of Default hereunder or under the Indenture, the Notes or any of the other
Security Documents shall have occurred and be continuing, the Partnership hereby
irrevocably constitutes and appoints Account Bank as the Partnership's true and
lawful attorney-in-fact, with full power of substitution, to execute,
acknowledge and deliver any instruments and to exercise and enforce every right,
power, remedy, option and privilege of the Partnership with respect to the
Collateral, and do in the name, place and stead of the Partnership, all such
acts, things and deeds for and on behalf of and in the name of the Partnership,
which the Partnership could or might do or which Account Bank or Trustee may
deem necessary or desirable to vest more fully in Account Bank, the rights and
remedies provided for herein and to accomplish the purposes of this Agreement.
The foregoing powers of attorney are irrevocable and coupled with an interest.
Subject to Paragraph 12(a) below, if the Partnership fails to perform any
agreement herein contained, Account Bank, acting upon the written direction of
Trustee, may itself perform or cause performance of any such agreement, and any
reasonable expenses of Account Bank and Trustee incurred in connection therewith
shall be paid by the Partnership as provided in Paragraph 10.

            12. LIABILITY OF TRUSTEE AND ACCOUNT BANK.

                  (a) Account Bank and Trustee shall be responsible for the
performance only of such of their respective duties as are specifically set
forth herein, and no duty shall be implied from any provision hereof or of the
Indenture or any other Security Document. Account Bank shall not be under any
obligation or duty to perform any act which would involve it in expense or
liability or to institute or defend any suit in respect hereof, or to advance
any of its own monies. The Partnership and, following the Permitted Merger Date,
MAALP, with regard to any time period on or after the Permitted Merger Date,
shall indemnify and hold Account Bank and Trustee, their respective employees,
directors, agents, officers and "control persons" within the meaning of the
Securities Act of 1933, as amended, and the Securities Exchange Act of 1934 as
amended, harmless from and against any loss, cost, liability, damage or expense
(including, without limitation, reasonable attorneys' fees and disbursements)
incurred by Account Bank or Trustee or such other persons in connection with the
transactions contemplated hereby or by the Indenture or any other Security
Document (unless a court of competent jurisdiction shall have determined,
subject to no further appeal, that such loss, cost, liability, damage or expense
has resulted solely from the gross negligence or willful misconduct of Account
Bank or Trustee, as the case may be) and shall make such indemnification
payments on a current basis.

                                      -11-

                  (b) Account Bank and Trustee shall each be protected in acting
upon any Officers' Certificate, notice, resolution, request, consent, order,
certificate, report, opinion, bond or other paper, document or signature
believed by it to be genuine, and Account Bank and Trustee may assume that any
Person purporting to give any of the foregoing in connection with the provisions
hereof has been duly authorized to do so. Account Bank and Trustee may consult
with counsel, and the opinion of such counsel shall be full and complete
authorization and protection in respect of any action taken or suffered by it
hereunder and in good faith in accordance therewith. Neither Account Bank nor
Trustee shall be liable to the Partnership for any act or omission done or
omitted to be done by Account Bank or Trustee in reliance upon any instruction,
direction or certification received by Account Bank from Trustee or by the
Trustee from Securityholders or the Partnership and without gross negligence or
willful or reckless misconduct of Account Bank or the Trustee.

                  (c) Account Bank is hereby authorized to provide information
in writing concerning the Accounts to such persons or entities as Trustee may
designate to Account Bank in writing, including, without limitation, the Rating
Agencies.

                  (d) If, at any time, Account Bank shall reasonably determine
that there is any dispute between any of the parties hereto with respect to the
holding or disposition of any funds in any Accounts hereunder, or if at any time
Account Bank is unable to determine, to Account Bank's satisfaction, the proper
disposition of any funds in the Accounts or Account Bank's proper actions with
respect to its obligations hereunder, then Account Bank may, in its sole
discretion, take either or both of the following actions:

                        (i)   suspend   the   performance   of   any   of  its
obligations under this Agreement until such dispute or uncertainty shall be
resolved to the sole satisfaction of Account Bank or until a successor Account
Bank shall have been appointed pursuant to Section 14 hereof; or

                        (ii)  petition (by means of an interpleader  action or
any other appropriate method) any court of competent jurisdiction in Charlotte,
North Carolina, for instructions with respect to such dispute or uncertainty,
and pay into such court all funds held by it in the Accounts for holding and
disposition in accordance with the instructions of such court.

Account Bank shall have no liability to any person with respect to any such
suspension of performance or disbursement into court, specifically including any
liability or claimed liability that may arise, or to be alleged to have arisen,
out of or as a result of any delay in the disbursement of funds held in the
Accounts or any delay in or with respect to any other action required or
requested of Account Bank.

                                      -12-

            13. CONTINUING SECURITY INTEREST. This Agreement shall create a
continuing security interest in the Collateral and shall remain in full force
and effect until the earlier of the Permitted Merger Date or payment in full of
the Notes. Upon the earlier of payment in full of the Notes or the occurrence of
the Permitted Merger Date, this Agreement shall terminate (subject to Paragraph
15) and the Partnership shall be entitled to the return, upon its request and at
its expense, of such of the Collateral as shall not have been sold or otherwise
applied pursuant to the terms hereof and Account Bank and/or Trustee shall
execute such instruments and documents prepared by the Partnership and delivered
to Account Bank or Trustee, including UCC-3 termination statements, as may be
reasonably requested by the Partnership to evidence such termination and the
release of the lien hereof.

            14. RESIGNATION OF ACCOUNT BANK. (a) Account Bank shall have the
right to resign as Account Bank hereunder upon thirty (30) days' prior written
notice to the Partnership, Trustee and the Rating Agencies, and in the event of
such resignation, the Partnership shall appoint a successor Account Bank which
may be any banking institution which has a rating on its unsecured debt by the
Rating Agencies not lower than "A" or its equivalent. No such resignation by
Account Bank shall become effective until a successor Account Bank shall have
accepted such appointment and executed an instrument by which it shall have
assumed all of the rights and obligations of Account Bank hereunder. If no such
successor Account Bank is appointed within sixty (60) days after receipt of the
resigning Account Bank's notice of resignation, the resigning Account Bank may
petition a court for the appointment of a successor Account Bank. Upon the
acceptance by the successor Account Bank of its appointment, the resigning
Account Bank shall be discharged from its duties and obligations hereunder.

                  (b) In connection with any resignation by Account Bank, (i)
the resigning Account Bank shall, at the sole cost of the Partnership, (A) duly
assign, transfer and deliver to the successor Account Bank this Agreement and
all cash and Permitted Investments held by it hereunder, (B) execute such
financing statements and other instruments prepared by the Partnership as may be
necessary to assign to the successor Account Bank the security interest in the
Collateral existing in favor of the retiring Account Bank hereunder and to
otherwise give effect to such succession and (C) take such other actions as may
be reasonably requested by the Partnership or the successor Account Bank in
connection with the foregoing and (ii) the successor Account Bank shall
establish in its name, as secured party, cash collateral accounts which shall
become the Accounts for purposes of this Agreement upon the succession of such
Account Bank.

            15. TERMINATION OF AGREEMENT. Promptly upon the earlier to occur of
(a) the receipt by Trustee of the notice from the Partnership specified in
Section 9.02(viii) of the Indenture or (b) the satisfaction and discharge of the
Indenture pursuant to Section 6.01 thereof, Trustee shall give written notice of
such event to Account Bank, Account Bank shall disburse all Collateral held by
it, in the Accounts or otherwise, to or at the direction of the Partnership, and
this Agreement shall terminate and be of no further force and effect; PROVIDED,
HOWEVER, that the provisions for the payment of fees and expenses set forth in
Paragraph 10 and the indemnification obligations of the Partnership and MAALP
set forth in Paragraph 12(a) shall continue in full force and effect.

                                      -13-

            16.   MISCELLANEOUS.

                  (a) This Agreement constitutes the entire and final agreement
between the parties with respect to the subject matter hereof and may not be
changed, terminated or otherwise varied, except by a writing duly executed by
the parties.

                  (b) No waiver of any term or condition of this Agreement,
whether by delay, omission or otherwise, shall be effective unless in writing
and signed by the party sought to be charged, and then such waiver shall be
effective only in the specific instance and for the purpose for which given.

                  (c) This Agreement shall be binding upon and inure to the
benefit of the parties hereto, their respective successors and permitted
assigns.
