                                   ARTICLE 2
                                 PURCHASE PRICE

The total purchase price to be paid by Buyer for the purchase of the Property is
as more particularly set forth in a Supplemental  Agreement dated as of the date
hereof  (the  "SUPPLEMENTAL  AGREEMENT")  between  Seller  and Buyer  ("PURCHASE
PRICE"). The Purchase Price shall be paid in the following manner:

      2.1 DEPOSIT  MONEY.  Within  three (3) business  days after the  Effective
      Date, and as a condition precedent to the effectiveness of this Agreement,
      Buyer  shall  deposit  an amount set forth in the  Supplemental  Agreement
      ("INITIAL EARNEST MONEY") with First American Title Insurance Company, 633
      Third Avenue, New York, New York 10017,  Attention:  Bruce Clay, as escrow
      agent  ("ESCROW  AGENT").  If Buyer approves or is deemed to have approved
      the  Property as set forth in Section 4.2 of this  Agreement,  Buyer shall
      deposit  an  additional  amount  set forth in the  Supplemental  Agreement
      ("ADDITIONAL  EARNEST  MONEY") with Escrow Agent (the  Additional  Earnest
      Money and the Initial Earnest Money are collectively  hereinafter referred
      to as the "DEPOSIT").  The Deposit shall be nonrefundable except as herein
      provided.   The  Deposit   shall  be  deposited  by  Escrow  Agent  in  an
      interest-bearing  account, and any interest earned on the Deposit shall be
      considered a part of the Deposit.  Except as expressly otherwise set forth
      herein,  the Deposit  shall be applied  against the Purchase  Price on the
      Closing Date.

      2.2 CASH AT  CLOSING.  On the Closing  Date,  Buyer shall pay to Seller an
      amount  equal  to  the  Purchase  Price,  subject  to the  prorations  and
      adjustments  set forth in Article 5 or as  otherwise  provided  under this
      Agreement,  plus any other amounts required to be paid by Buyer at Closing
      (as  defined in  Section  6.1),  in  immediately  available  funds by wire
      transfer as more particularly set forth in Section 6.2.

                                   ARTICLE 3
                                  TITLE MATTERS

      3.1 TITLE TO REAL  PROPERTY.  Seller has  delivered to Buyer a preliminary
      title  report for the Real  Property,  together  with  copies of all items
      shown  as   exceptions   to  title  in  the   preliminary   title   report
      (collectively,  the  "TITLE  REPORT")  prepared  by First  American  Title
      Insurance  Company  ("TITLE  COMPANY").  Buyer has ordered and is awaiting
      receipt  of an ALTA  As-Built  survey  of the  Real  Property  ("SURVEY").
      Fifteen (15) business  days after Buyer's  receipt of the Title Report and
      Survey ("APPROVAL DATE"),  Buyer shall provide written notice to Seller of
      any matters shown by the Title Report or Survey which are not satisfactory
      to Buyer  ("TITLE  Notice").  In the event Buyer  disapproves  one or more
      items in the Title Notice  ("DISAPPROVED  EXCEPTIONS"),  then, within five
      (5) business  days after  receipt of the Title  Notice,  Seller may notify
      Buyer  in  writing  of  Seller's  election  to  cause  one or  more of the
      Disapproved  Exceptions  to be  eliminated  prior to the Closing  Date (as
      defined below), or, alternatively, Seller may notify Buyer in writing that
      Seller  does not  intend to take  action to  eliminate  one or more of the
      Disapproved  Exceptions  (alternatively,   "SELLER'S  NOTICE").   Seller's
      failure to timely  deliver  Seller's  Notice shall be deemed to constitute
      Seller's  election not to take action to eliminate any of such Disapproved
      Exceptions.  Except as provided below,  Seller shall have no obligation to
      cause any of the Disapproved Exceptions to be eliminated.

                                       2
<PAGE>

Within three (3) business days after the earlier to occur of (i) Buyer's receipt
of Seller's  Notice  specifying  which  Disapproved  Exceptions  Seller does not
intend to  eliminate,  or (ii) the date on which  Seller  last could have timely
delivered  Seller's  Notice,  Buyer shall have the right to accept  title to the
Real Property  subject to such Disapproved  Exceptions,  provided Buyer notifies
Seller in writing of such  acceptance  within such five (5) business day period.
Buyer's  failure to so notify  Seller  within such five (5)  business day period
shall be deemed  to  constitute  Buyer'  election  to  approve  the  Disapproved
Exceptions and to purchase the Property  subject to the Disapproved  Exceptions.
The term "Permitted  Exceptions"  shall  hereinafter  refer to (a) title matters
approved  or  deemed  approved  by  Buyer  pursuant  to  this   paragraph,   (b)
nondelinquent  real property  taxes,  (c) any  exceptions  caused by Buyer,  its
agents,  representatives or employees, (d) the printed terms and conditions in a
ALTA (or equivalent form customarily used in the jurisdiction where the Property
is located) Owner's  Extended  Coverage Title Insurance  Policy,  (e) applicable
zoning  and  building  ordinances  and land use  regulations  and (f) the Lease.
Notwithstanding  anything to the contrary,  except as may be expressly  provided
with respect to Buyer's  assumption of the existing bond  financing,  if any, in
all other instances,  Seller shall remove prior to the Closing Date, at Seller's
sole cost and  expense,  the lien of any deed of trust or  mortgage  encumbering
Seller's  interest  in the Real  Property  and the lien of any  delinquent  real
property taxes encumbering the Real Property. Prior to the Closing, Seller shall
provide to Title  Company an affidavit  stating the name of the single tenant of
the Real Property.  Notwithstanding  any provision to the contrary  contained in
this Agreement or any of the documents to be executed in connection  herewith or
pursuant hereto, any or all of the Permitted Exceptions may be omitted by Seller
in the Deeds (as  defined  in  Subsection  6.3(a))  without  giving  rise to any
liability  of  Seller,  irrespective  of any  covenant  or  warranty  of  Seller
contained in the Deeds (which  provisions  shall  survive the Closing and not be
merged therein).

            3.1.1  DISCHARGE OF TITLE  OBJECTIONS.  If on the Closing Date there
            are  any  Title  Objections  which  Seller  has  elected  to pay and
            discharge,  Seller  may use any  portion  of the  Purchase  Price to
            satisfy the same,  provided Seller shall either (a) deliver to Buyer
            at the Closing  instruments  in  recordable  form and  sufficient to
            cause such Title Objections to be released of record,  together with
            the cost of recording or filing such  instruments,  or (b) cause the
            Title Company to insure over the same,  without any additional  cost
            to Buyer,  whether such insurance is made available in consideration
            of payment, bonding, indemnity of Seller or otherwise.

      3.2 TITLE INSURANCE. At Closing, the Title Company shall issue to Buyer an
      ALTA  Owner's  Form of title  insurance  policy  in the form of the  Title
      Report  ("OWNER'S  TITLE  POLICY"),  in the amount of the Purchase  Price,
      insuring  that fee simple  title to the Real  Property  is vested in Buyer
      subject  only to the  Permitted  Exceptions.  Buyer  shall be  entitled to
      request that the Title Company provide such  endorsements  (or amendments)
      to the Owner's Title Policy as Buyer may reasonably require, provided that
      (a) such  endorsements  (or amendments)  shall be at no cost to, and shall
      impose no additional  liability on, Seller, (b) Buyer's  obligations under
      this  Agreement  shall not be conditioned  upon Buyer's  ability to obtain
      such  endorsements  and, if Buyer is unable to obtain  such  endorsements,
      Buyer shall  nevertheless be obligated to proceed to close the transaction
      contemplated by this Agreement ("TRANSACTION") without reduction of or set
      off against the Purchase  Price,  and (c) the Closing shall not be delayed
      as a result of Buyer's request.

                                   ARTICLE 4
                 BUYER'S DUE DILIGENCE/CONDITION OF THE PROPERTY

      4.1  BUYER'S  INSPECTIONS  AND  DUE  DILIGENCE.  Buyer  acknowledges  that
      commencing  prior to the execution of this  Agreement and continuing for a
      period which will expire on July 8, 2005 ("DUE DILIGENCE  PERIOD"),  Buyer
      has  conducted,   and  shall  continue  to  conduct,   its   examinations,
      inspections,  testing,  studies and/or investigations (herein collectively
      called the "DUE  DILIGENCE") of the Property.  By way of example,  and not
      limitation,   the  Due  Diligence  shall  include  Buyer's  evaluation  of
      information   regarding  the  Property  and  such  documents  in  Seller's
      possession applicable to the Property,  including, but not limited to, the
      Title Report, the Survey, the Lease, the Contracts, the Property Documents
      (as defined in Subsection  6.3(l)),  the  environmental  reports listed on
      Exhibit B attached hereto and incorporated  herein by this reference,  and
      such other nonproprietary,  nonprivileged  reports,  documents,  books and
      records  which  pertain to the  Property as Buyer has deemed or shall deem
      necessary or  appropriate  (all of the  foregoing  documents  being herein
      collectively  called the  "DOCUMENTS").  Buyer shall not have the right to
      perform  any  invasive  testing of the  Property  without  Seller's  prior
      written  consent,  which  Seller may give or  withhold,  in Seller's  sole
      discretion.  In  connection  with  such  due  diligence,  subject  to  the
      limitations in Section 1.2, Seller shall deliver any documents  reasonably
      requested by Buyer and in the  possession  of Seller or Seller's  property
      manager, within three (3) business days following such request.

      4.2 TERMINATION OF AGREEMENT DURING DUE DILIGENCE  PERIOD. If Buyer is not
      satisfied,  in  Buyer's  sole  discretion,  with  the  results  of its Due
      Diligence  during  the Due  Diligence  Period,  Buyer may  terminate  this
      Agreement  by  written  notice  to  Seller  given in  accordance  with the
      provisions  of Section 14.9 hereof at any time prior to 5:00 p.m.  Central
      Time on the last day of the Due  Diligence  Period,  and,  in the event of
      such  termination,  neither  Seller  nor Buyer  shall  have any  liability
      hereunder  except  for  those  obligations  which  expressly  survive  the
      termination of this Agreement and Buyer shall be entitled to the return of
      the Deposit. In the event Buyer fails to terminate this Agreement prior to
      5:00 p.m. Central Time on the last day of the Due Diligence Period,  Buyer
      shall be deemed to have waived its rights to terminate  this  Agreement in
      accordance  with this  Article 4 and shall be  obligated  to  deliver  the
      Additional  Earnest Money to the Escrow Agent.  Subject to Seller's  prior
      approval, which shall not be unreasonably withheld or delayed, Buyer shall
      have the right after the expiration of the Due Diligence Period to conduct
      further  physical  examinations,   inspections,  testing,  studies  and/or
      investigations  regarding the Property, but such additional  examinations,
      inspections,  testing,  studies and/or investigations shall not extend the
      Due Diligence Period.

      4.3 BUYER'S  CERTIFICATE.  Buyer shall deliver to Seller at the Closing, a
      certificate  in the form of  Exhibit C attached  hereto  and  incorporated
      herein by this reference.

                                   ARTICLE 5
                           ADJUSTMENTS AND PROBATIONS

The following adjustments and proration shall be made at Closing or at such time
as agreed between the parties:

      5.1 LEASE RENTALS AND EXPENSES. Subject to the provisions of this Section,
      Rent (as defined below) shall be prorated as of the Closing.  Seller shall
      be entitled to all Rents attributable to any period prior to and including
      the day on which the  Closing  occurs,  and Buyer shall be entitled to all
      Rent attributable to any period after the day on which the Closing occurs.
      "RENT" as used herein shall mean the fixed  monthly  rents and  escalation
      rents and any tax and operating  cost  reimbursements  due from the tenant
      under the Lease. Tax reimbursements  include, but are not limited to, real
      property tax  reimbursements.  Pursuant to the terms of the Lease, rent is
      paid  monthly,  in arrears.  At Closing,  Seller shall be entitled to, and
      receive a credit  for all  accrued  but  unpaid  Rent and  which  right to
      collect same shall be assigned to Buyer. In addition,  in the event Seller
      shall have paid any tax reimbursements  which remain due and unpaid by the
      tenant under the Lease,  Seller shall  receive at Closing a credit for any
      such tax  reimbursement  and which right to collect same shall be assigned
      to Buyer at Closing.  Seller's and Buyer's  rights and  obligations  under
      this section shall survive the Closing.

      5.2 TAXES.  Real estate taxes and assessments on the Property shall not be
      prorated as such costs are the  obligation  of the tenant  under the Lease
      and will be reimbursed  pursuant to the terms thereof.  Buyer shall accept
      the property subject to all non-delinquent taxes and assessments and shall
      subsequently  be responsible for the payment of same and collection of the
      reimbursement  from the tenant under the Lease. As provided in Section 5.1
      herein,  in the event  Seller  shall have paid any real  estate  taxes and
      assessments  on the Property and  submitted  same for  reimbursement  from
      tenant  pursuant to the terms of the Lease,  Seller shall receive a credit
      for  such  reimbursement  at  Closing  and  which  right to  collect  such
      reimbursement  shall be  assigned  to Buyer at  Closing.  Seller  shall be
      entitled to retain the full amount of any tax refund  received by Buyer or
      Seller after the Closing and attributable to a period prior to the Closing
      to the extent such refund is not owed to the tenant pursuant to the Lease.
      Buyer shall promptly  deliver the full amount of such tax refund to Seller
      if it is received by Buyer.

      5.3 UTILITIES.  Seller shall attempt to cause the utility and water meters
      to be read by the  applicable  utility  provider  on the day  prior to the
      Closing or as close to the  Closing as is possible if a reading on the day
      prior to the Closing cannot be obtained,  and shall be responsible for the
      cost of all  utilities  and water used  prior to that time,  except to the
      extent such utility charges are billed to and paid by tenants directly. To
      the  extent  utility  readings  cannot  be taken  on the day  prior to the
      Closing,  Buyer and Seller shall reasonably estimate what the readings are
      likely to have been as of the Closing  based on the actual  reading,  when
      the actual  reading  occurred and such  information as may be available to
      Buyer and Seller  relating to daily usage  rates.  Any security or service
      deposits  delivered  by  Seller to  utility  providers,  and any  interest
      required  to be paid  thereon,  shall be and remain the sole  property  of
      Seller, and any refund of such security deposits shall be made directly to
      Seller  except to the extent such deposits are assigned to Buyer by Seller
      in which case,  Buyer shall be debited and Seller  credited  the amount of
      such assigned deposits. On the Closing,  except to the extent such utility
      accounts  are in the name of the tenant,  Buyer  shall cause all  accounts
      with utility  companies to be changed to its name,  and all utility  bills
      for periods from and after the Closing shall be paid by Buyer.

      5.4 CLOSING COSTS.  Buyer shall pay (a) the cost of all  endorsements  and
      all premiums and charges of the Title Company for the Owner's Title Policy
      (b)  the  cost of  updating  the  Survey,  (c) all  recording  charges  in
      connection with the instruments by which Seller conveys the Property,  (d)
      one-half of all escrow  charges,  (e) all costs of Buyer's Due  Diligence,
      including fees due its  consultants  and attorneys,  (f) all lenders' fees
      related to any financing to be obtained by Buyer, if any, (g) all personal
      property  taxes  and (h) all  mortgage  registration  taxes  and any other
      recording fees, taxes or other expenses  applicable to any financing to be
      obtained by Buyer and the cost of all  endorsements  and all  premiums and
      charges of the Title  Company  for any Loan Title  Policy  relating to any
      financing  to be obtained by Buyer.  Seller  shall pay (a) one-half of all
      escrow  charges,  (b) all fees due its attorneys,  and (c) all documentary
      transfer  taxes  applicable  to the  transfer  of a  parcel  of  the  Real
      Property,  if any. The  obligations  of the parties under this Section 5.4
      shall  survive  the  Closing  (and not be merged  therein)  or any earlier
      termination of this Agreement.

      5.5 Intentionally Deleted.

      5.6 APPORTIONMENT  CREDIT.  In the event the  apportionments to be made at
      the Closing  result in a credit  balance  (i) to Buyer,  such sum shall be
      paid at the Closing by giving Buyer a credit against the Purchase Price or
      (ii) to Seller, Buyer shall pay the amount of the credit to Seller through
      escrow on the Closing in addition to the Purchase Price.

      5.7  DELAYED  ADJUSTMENT;   DELIVERY  OF  OPERATING  AND  OTHER  FINANCIAL
      STATEMENTS.  If at any time  following the Closing Date,  the amount of an
      item listed in any section of this  Article 5 shall prove to be  incorrect
      (whether as a result in an error in  calculation or a lack of complete and
      accurate  information  as of the  Closing),  the party in whose  favor the
      error was made shall  promptly pay to the other party the sum necessary to
      correct such error upon receipt of proof of such error, provided that such
      proof is  delivered  to the party  from whom  payment is  requested  on or
      before  eighteen (18) months after Closing (such period being  referred to
      herein as the "POST CLOSING ADJUSTMENT PERIOD"). In order to enable Seller
      to determine whether any such delayed adjustment is necessary, Buyer shall
      provide to Seller  current  operating  and  financial  statements  for the
      Property no later than the date one (1) month prior to the  expiration  of
      the  Post-Closing  Adjustment  Period  and at other  times  upon  Seller's
      written  request.  The  provisions  of this Section 5.7 shall  survive the
      Closing and not be merged therein.

      5.8 PURCHASE PRICE  ADJUSTMENT.  If the actual operating  expenses for the
      Property  for the first year of  operation,  as  verified  by the  current
      property  manager  ("ACTUAL  OPERATING  EXPENSES"),  are greater  than the
      operating  expenses  set forth in the Argus run that was provided to Buyer
      by Seller  as set forth in  Exhibit R  attached  hereto  and  incorporated
      herein by this reference (the "ARGUS RUN OPERATING EXPENSES") by more than
      3%, the Purchase Price will be reduced by an amount equal to the amount by
      which Actual Operating Expenses exceed the Argus Run Operating Expenses by
      more than 3%, divided by a 7% capitalization rate. If the Actual Operating
      Expenses are less than the Argus Run  Operating  Expenses by more than 3%,
      the  Purchase  Price will be increased by an amount equal to the amount by
      which  Actual  Operating  Expenses  are less than the Argus Run  Operating
      Expenses by more than 3%, divided by a 7%  capitalization  rate. The first
      year of operation  shall be defined as the one year period  beginning  the
      earlier  of  (i)  The  receipt  of  an  Acceptance/Rent  Start  Letter  or
      Supplemental Lease Agreement executed by tenant; or (ii) the issuance of a
      permanent certificate of occupancy for the Property. The reconciliation of
      Actual  Operating  Expenses  and  Argus  Run  Operating  Expenses  for the
      purchase  price  adjustment as set forth in this Section 5.8 shall include
      only  those  expenses  specifically  itemized  in the Argus Run  Operating
      Expenses and such additional  expenses that were incurred  pursuant to the
      Lease. Any expenses not identified by line item in the Argus Run Operating
      Expenses  will  not be  included  in a  reconciliation  to  calculate  the
      purchase price  adjustment  unless such additional  expenses were incurred
      pursuant to the lease. As set forth in Section 9.1.4 of this Agreement, CB
      Richard Ellis and BC Development Company will act as property managers for
      the Property (the "Property Manager").  During the first year of operation
      of the  Property,  Buyer  will  act in good  faith  and in a  commercially
      reasonable  manner  and will not cause  Annual  Operating  Expenses  to be
      increased in comparison  to the Argus Run Operating  Expenses by directing
      the Property  Manager to conduct daily business in a manner contrary to of
      the  expenses  itemized  in the Argus  Run  Operating  Expenses  and those
      expenses required in the Lease.  During the first year of operation of the
      Property,  Seller will act in good faith an in a  commercially  reasonable
      manner and will not cause  Annual  Operating  Expenses to be  decreased in
      comparison  to the Argus Run  Operating  Expenses  by  directing  Property
      Manager  to  conduct  daily  business  in  a  manner   contrary  to  those
      requirements  under the Lease and those expenses  necessary to operate and
      maintain the building in a first-class  office  building.  If Buyer causes
      Annual Operating  Expenses to increase as a result of actions that are not
      consistent  with  those  expenses  itemized  in the  Argus  Run  Operating
      Expenses and those expenses that should be incurred pursuant to the Lease,
      such resulting amount of increase in Annual Operating Expenses will not be
      included in a reconciliation for the purchase price adjustment.  If Seller
      causes Annual  Operating  Expenses to decrease as a result of actions that
      are not consistent with those expenses itemized in the Argus Run Operating
      Expenses,  or  necessary  to  operate  and  maintain  the  building  in  a
      first-class office manner, or necessary additional expenses that should be
      incurred  pursuant  to the Lease,  such  resulting  amount of  decrease in
      Annual Operating Expenses will not be included in a reconciliation for the
      purchase price adjustment.

            Buyer  shall be "deemed to know" that a  representation  or warranty
            was  untrue,  inaccurate  or  incorrect  to  the  extent  that  this
            Agreement,  the Documents,  any estoppel certificate executed by any
            tenant  of the  Property  and  delivered  to Buyer,  or any  Buyer's
            Representatives,   or   otherwise   obtained  by  Buyer  or  Buyer's
            Representatives contains information which is inconsistent with such
            representation or warranty.

            8.3.4  Notice  of  Breach;  Seller's  Right  to Cure.  If after  the
            expiration  of the Due  Diligence  Period but prior to the  Closing,
            Buyer or any Buyer's  Representative  obtains actual  knowledge that
            any of the  representations  or warranties made herein by Seller are
            untrue, inaccurate or incorrect in any material respect, Buyer shall
            give Seller  written notice thereof within five (5) business days of
            obtaining such knowledge (but, in any event,  prior to the Closing).
            If at or prior to the Closing,  Seller obtains actual knowledge that
            any of the  representations  or warranties made herein by Seller are
            untrue,  inaccurate  or incorrect in any  material  respect,  Seller
            shall give Buyer  written  notice  thereof  within five (5) business
            days of obtaining  such knowledge  (but, in any event,  prior to the
            Closing).  In either such event, Seller shall have the right to cure
            such  misrepresentation  or  breach  and  shall  be  entitled  to  a
            reasonable  adjournment  of the Closing  (not to exceed  ninety (90)
            days) for the  purpose of such cure.  If Seller is unable to so cure
            any  misrepresentation or breach, then Buyer, as its sole remedy for
            any and all such materially untrue, inaccurate or incorrect material
            representations or warranties,  shall elect either (a) to waive such
            misrepresentations or breaches of representations and warranties and
            consummate  the  Transaction  without  any  reduction  of or  credit
            against the Purchase  Price,  or (b) to terminate  this Agreement by
            written  notice given to Seller on the Closing  Date, in which event
            this  Agreement  shall be terminated , the Deposit shall be returned
            to Buyer, Seller shall reimburse Buyer for all reasonable legal fees
            and the costs of third party  reports,  not to exceed  $50,000  and,
            thereafter,   neither  party  shall  have  any  further   rights  or
            obligations  hereunder except as provided in any section hereof that
            by its terms expressly  provides that it survives any termination of
            this Agreement.  If any such  representation  or warranty is untrue,
            inaccurate or incorrect  but is not untrue,  inaccurate or incorrect
            in any  material  respect,  Buyer  shall be  deemed  to  waive  such
            misrepresentation or breach of warranty, and Buyer shall be required
            to  consummate  the  Transaction  without any reduction of or credit
            against the Purchase Price. The untruth, inaccuracy or incorrectness
            of a  representation  or warranty  shall be deemed  material only if
            Buyer's aggregate damages resulting from the untruth,  inaccuracy or
            incorrectness  of any  of  the  representations  or  warranties  are
            reasonably  estimated  to exceed an amount in excess of One  Hundred
            Thousand  and No/100  ($100,000.00)  Dollars.  A default of Seller's
            representation under Section 8.2.2(e) shall be deemed material.

            8.3.5   Survival;    Limitation   on   Seller's    Liability.    The
            representations  and warranties  made by Seller in Section 8.2 shall
            survive the  Closing  and not be merged  therein for a period of one
            hundred  eighty  (180) days and Seller shall only be liable to Buyer
            hereunder for a breach of a representation  and warranty made herein
            or in any of the  documents  executed by Seller at the Closing  with
            respect  to  which a claim  is made by Buyer  against  Seller  on or
            before  the two  hundred  tenth  (210t)  day  after  the date of the
            Closing. Anything in this Agreement to the contrary notwithstanding,
            the maximum  aggregate  liability of Seller for Seller's breaches of
            representations  and warranties herein or in any documents  executed
            by Seller at Closing (including, but not limited to, any of Seller's
            representation  letters  delivered  pursuant to Subsection  6.3 (j))
            shall  be   limited   as  set  forth  in   Section   14.15   hereof.
            Notwithstanding the foregoing, however, if the Closing occurs, Buyer
            hereby  expressly  waives,  relinquishes  and  releases any right or
            remedy  available to it at law, in equity or under this Agreement to
            make a claim against Seller for damages that Buyer may incur,  or to
            rescind this Agreement and the Transaction,  as the result of any of
            Seller's  representations or warranties being untrue,  inaccurate or
            incorrect  if  (a)  Buyer  knew  or is  deemed  to  know  that  such
            representation  or warranty was untrue,  inaccurate  or incorrect at
            the time of the Closing,  or (b) Buyer's damages as a result of such
            representations or warranties being untrue,  inaccurate or incorrect
            are  reasonably  estimated to aggregate less than an amount equal to
            One Hundred Thousand and No/100 ($100,000.00) Dollars.

                                    COVENANTS

      9.1 BUYER'S COVENANTS. Buyer hereby covenants as follows:

            9.1.1  Confidentiality.  Buyer  acknowledges  that  any  information
            heretofore  or  hereafter  furnished  to Buyer  with  respect to the
            Property  has been and will be so furnished  on the  condition  that
            Buyer maintain the confidentiality thereof. Accordingly, Buyer shall
            hold,  and shall cause its directors,  officers and other  personnel
            and representatives to hold, in strict confidence,  and not disclose
            to any other  person  without  the prior  written  consent of Seller
            until  the  Closing  shall  have  been   consummated,   any  of  the
            information  in  respect  of the  Property  delivered  to or for the
            benefit  of Buyer  whether  by  agents,  consultants,  employees  or
            representatives  of  Buyer  or by  Seller  or  any  of  its  agents,
            representatives  or  employees,  including,  but not limited to, any
            information  heretofore  or  hereafter  obtained  by Buyer or any of
            Buyer's Representatives in connection with any studies, inspections,
            testings  or  analyses  conducted  by  Buyer  as  part  of  its  due
            diligence. In the event the Closing does not occur or this Agreement
            is terminated,  Buyer shall promptly  return to Seller all copies of
            documents  delivered  by  Seller  to  Buyer  containing  any of such
            information without retaining any copy thereof or extract therefrom.
            Notwithstanding  anything  to the  contrary  hereinabove  set forth,
            Buyer may disclose such  information (i) on a need-to-know  basis to
            its employees, consultants, members of professional firms serving it
            or  potential  lenders,  and  (ii) as any  governmental  agency  may
            require in order to comply with applicable municipal,  county, state
            or federal statutes,  codes, ordinances,  laws, rules or regulations
            (herein   collectively  called  "LAWS").   The  provisions  of  this
            Subsection 9.1.1 shall survive any termination of this Agreement.

            9.1.2 Buyer's Indemnity; Delivery of Reports. Buyer hereby agrees to
            indemnify,  defend,  and  hold  Seller  free and  harmless  from and
            against any and all costs, losses, damages and expenses, of any kind
            or nature whatsoever (including reasonable attorneys' fees and costs
            but excluding punitive damages) arising out of or resulting from the
            breach of the terms of  Subsection  9.1.1 or the  entry  and/or  the
            conduct of  activities  upon the Property by Buyer or any of Buyer's
            Representatives  in connection with the  inspections,  examinations,
            testings and  investigations  of the Property  conducted at any time
            prior to the Closing, which indemnity shall survive the Closing (and
            not be merged therein) or any earlier termination of this Agreement.
            Buyer shall  deliver  promptly  to Seller  copies of all third party
            reports commissioned by or on behalf of Buyer evidencing the results
            of tests, studies or inspections of the Property.

            9.1.3 Limit on Government Contacts. Notwithstanding any provision in
            this  Agreement  to the  contrary,  except  in  connection  with the
            preparation  of a  so-called  "Phase I"  environmental  report  with
            respect to the  Property,  Buyer shall not contact any  governmental
            official or representative  regarding  Hazardous Materials on or the
            environmental  condition  of the  Property  without  Seller's  prior
            written  consent  thereto,  which consent shall not be  unreasonably
            withheld.  In  addition,  if Seller's  consent is obtained by Buyer,
            Seller  shall be  entitled  to  receive at least five (5) days prior
            written notice of the intended  contact and to have a representative
            present  when  Buyer  has any such  contact  with  any  governmental
            official or  representative.  As used  herein,  the term  "HAZARDOUS
            MATERIAL" shall mean any substance, chemical, waste or material that
            is or becomes regulated by any federal,  state or local governmental
            authority  because of its toxicity,  infectiousness,  radioactivity,
            explosiveness, ignitability, corrosiveness or reactivity, including,
            without limitation,  asbestos or any substance  containing more than
            0.1   percent   asbestos,   the   group   of   compounds   known  as
            polychlorinated biphenyls,  flammable explosives,  oil, petroleum or
            any refined petroleum product.

            9.1.4 Property Management  Agreement.  Buyer agrees that Buyer shall
            enter into a Property Management Agreement with CB Richard Ellis and
            BC  Development  Company for the  management  of the Property  after
            Closing in accordance with Property  Management  Agreement  attached
            hereto as Exhibit N and incorporated herein by reference.

            9.1.5 No Contact with  Tenant.  Buyer agrees not to make any contact
            with the tenant of the Property  without  first  obtaining the prior
            written  consent of Seller.  In  addition,  if  Seller's  consent is
            obtained by Buyer, Seller shall be entitled to receive at least five
            (5) days prior written notice of the intended  contact and to have a
            representative  present  when  Buyer has any such  contact  with the
            tenant.

      9.2 SELLER'S COVENANTS. Seller hereby covenants as follows:

            9.2.1  Service  Contracts.  Without  Buyer's  prior  consent,  which
            consent shall not be unreasonably withheld,  between the date hereof
            and the Closing  Date Seller  shall not  extend,  renew,  replace or
            modify any Contract  unless such contract (as so extended,  renewed,
            replaced or modified) can be terminated by the owner of the Property
            without penalty on not more than thirty (30) days' notice.

            9.2.2  Maintenance  of  Property.  Except  to the  extent  Seller is
            relieved of such obligations by Article 11 hereof,  between the date
            hereof and the Closing  Date,  Seller  shall  maintain  and keep the
            Property in a manner  consistent  with Seller's past  practices with
            respect to the Property; provided, however, that, subject to Buyer's
            right to terminate this Agreement prior to the expiration of the Due
            Diligence  Period in accordance  with the terms of Article 4 hereof,
            Buyer hereby  agrees that it shall  accept the Property  subject to,
            and Seller shall have no obligation to cure,  (i) any  violations of
            Laws,  and (ii) any  physical  conditions  which  would give rise to
            violations  of Laws,  which,  with  respect to both  clauses (i) and
            (ii), exist on the last day of the Due Diligence Period and of which
            Buyer has actual knowledge.  Between the date hereof and the Closing
            Date, Seller will advise Buyer of any written notice Seller receives
            after  the  date  hereof  from  any  governmental  authority  of the
            violation  of  any  Laws  regulating  the  condition  or  use of the
            Property.

            9.2.3  Access to  Property.  Between the date hereof and the Closing
            Date, Seller shall allow Buyer or Buyer's  representatives access to
            the  Property  upon  reasonable  prior  notice at  reasonable  times
            provided (a) such access does not  interfere  with the  operation of
            the Property or the rights of the tenant;  (b) after the  expiration
            of the Due Diligence Period, Buyer shall not be permitted to perform
            any further  testing or other  physical  evaluation  of the Property
            prior to Closing  except with Seller's  prior written  consent;  (c)
            Seller  or its  designated  representative  shall  have the right to
            pre-approve,  in Seller's sole discretion, and be present during any
            physical  testing of the  Property;  and (d) Buyer shall  return the
            Property  to  the  condition   existing  prior  to  such  tests  and
            inspections.

            9.2.4 Within five (5) business days  following  the Effective  Date,
            Seller shall submit a request to the Contracting  Officer to execute
            and  deliver a  Statement.  Seller  shall use good faith  efforts to
            obtain such Statement from the Contracting Officer.

            9.2.5 Seller shall,  without  incurring any expense,  cooperate with
            efforts of Buyer to obtain any title related  estoppel  certificates
            that Buyer may require.

      9.3 MUTUAL COVENANTS.

            9.3.1 Publicity. Seller and Buyer each hereby covenant that prior to
            and after the Closing neither Seller nor Buyer shall issue any press
            release  or public  statement  (a  "RELEASE")  with  respect  to the
            Transaction  without the prior  consent of the other,  which consent
            may be granted or withheld in the sole discretion of Seller,  except
            to the extent  required by applicable Law. If either Seller or Buyer
            is required by applicable Law to issue a Release,  such party shall,
            at least two (2)  business  days prior to the  issuance of the same,
            deliver a copy of the  proposed  Release to the other  party for its
            review.

            9.3.2 Broker.  Seller and Buyer expressly acknowledge that Gary Carr
            and Russell Ingrum of CB Richard Ellis,  Inc.  ("BROKER") have acted
            as the  exclusive  broker with respect to the  Transaction  and with
            respect to this  Agreement,  and that Seller shall pay the brokerage
            commission due to Broker in accordance  with the separate  agreement
            between  Seller  and  Broker  if  this  Transaction  closes  but not
            otherwise,  anything  to  the  contrary  in the  separate  agreement
            between Seller and Broker  notwithstanding (it being understood that
            the payment of the Purchase  Price to Seller and the  performance of
            all of  Buyer's  obligations  hereunder  to  Seller  are  conditions
            precedent to Seller's obligation to pay any brokerage commission due
            Broker under the separate  agreement between Seller and Broker).  By
            its execution hereof,  Broker acknowledges that Cathy Howard and Jon
            Walker  (collectively the "PARTICIPATING  BROKER") are participating
            brokers and Broker shall pay the Participating  Broker in accordance
            with the separate agreement between Broker and Participating  Broker
            if this Transaction closes but not otherwise.  Seller agrees to hold
            Buyer  harmless  and  indemnify  Buyer from and  against any and all
            damages,   costs  or  expenses  (including,   but  not  limited  to,
            reasonable attorneys' fees and disbursements) suffered by Buyer as a
            result of any claims by any party  (other than  Broker)  claiming to
            have   represented   Seller  as  broker  in   connection   with  the
            Transaction.  Buyer  agrees to hold Seller  harmless  and  indemnify
            Seller  from and  against  any and all  damages,  costs or  expenses
            (including,  but not  limited  to,  reasonable  attorneys'  fees and
            disbursements)  suffered  by Seller as a result of any claims by any
            party  (other than  Broker)  claiming to have  represented  Buyer as
            broker in connection with the Transaction.

            9.3.3 Tax Protests;  Tax Refunds and Credits.  Seller shall have the
            right to  continue  and to control  the  progress of and to make all
            decisions  with  respect to any contest of the real estate taxes and
            personal  property  taxes for the  Property  due and payable for the
            calendar  year in which the  Closing  occurs and all prior  calendar
            years.  Buyer shall have the right to control the progress of and to
            make all  decisions  with  respect  to any tax  contest  of the real
            estate  taxes and personal  property  taxes for the Property due and
            payable for all calendar  years  subsequent  to the calendar year in
            which the Closing occurs.  All real estate and personal property tax
            refunds and  credits  received  after  Closing  with  respect to the
            Property shall be applied in the following order of priority: first,
            to pay the costs and expenses (including  reasonable attorneys' fees
            and expenses)  incurred in connection with obtaining such tax refund
            or credit;  second, to pay any amounts due to tenant of the Property
            as a result of such tax  refund or  credit  to the  extent  required
            pursuant to the terms of the Lease; and third,  apportioned  between
            Buyer and Seller as follows:

                  (a) with  respect to any  refunds or credits  attributable  to
real estate and personal  property taxes assessed for the calendar year in which
the Closing  occurs  (regardless of the year for which such taxes are assessed),
such  refunds  and  credits  shall be  apportioned  between  Buyer and Seller in
proportion to the number of days in such calendar year that each party owned the
Property  (with title to the  Property  being  deemed to have passed as of 12:01
a.m. on the Closing Date);

                  (b) with  respect to any  refunds or credits  attributable  to
real estate and  personal  property  taxes  assessed for any period prior to the
calendar  year in which the  Closing  occurs,  Seller  shall be  entitled to the
entire refunds and credits; and

                  (c) with  respect to any  refunds or credits  attributable  to
real  estate and  personal  property  taxes  assessed  for any period  after the
calendar year in which the Closing occurs, Buyer shall be entitled to the entire
refunds and credits.

            9.3.4 Survival. The provisions of this Section 9.3 shall survive the
            Closing (and not be merged  therein) or earlier  termination of this
            Agreement.

                              FAILURE OF CONDITIONS

      10.1 TO SELLER'S OBLIGATIONS.  If, on or before the Closing Date, Buyer is
      in default of any of its obligations under this Agreement, then Seller may
      elect to (a) terminate this  Agreement by written notice to Buyer;  or (b)
      proceed to close the Transaction. If this Agreement is so terminated, then
      Seller shall be entitled to retain the Deposit as liquidated damages,  and
      thereafter  neither party to this Agreement  shall have any further rights
      or obligations  hereunder  other than any arising under any section herein
      which  expressly  provides  that  it  survives  the  termination  of  this
      Agreement.

IN THE EVENT THE CONSUMMATION OF THE TRANSACTION  HEREIN  CONTEMPLATED  DOES NOT
OCCUR AS HEREIN  PROVIDED  BY REASON OF ANY  DEFAULT OF BUYER,  BUYER AND SELLER
AGREE THAT IT WOULD BE  IMPRACTICAL  AND  EXTREMELY  DIFFICULT  TO ESTIMATE  THE
DAMAGES  WHICH  SELLER MAY SUFFER.  THEREFORE,  BUYER AND SELLER DO HEREBY AGREE
THAT A REASONABLE  ESTIMATE OF THE DAMAGES THAT SELLER WOULD SUFFER IN THE EVENT
THAT BUYER  DEFAULTS  AND FAILS TO COMPLETE  THE PURCHASE OF THE PROPERTY IS AND
SHALL BE, AS SELLER'S SOLE AND EXCLUSIVE  REMEDY  (WHETHER AT LAW OR IN EQUITY),
AN AMOUNT EQUAL TO THE DEPOSIT (WHICH  INCLUDES ANY ACCRUED  INTEREST  THEREON).
SAID AMOUNT SHALL BE THE FULL,  AGREED AND LIQUIDATED  DAMAGES FOR THE BREACH OF
THIS  AGREEMENT BY BUYER,  ALL OTHER CLAIMS TO DAMAGES OR OTHER  REMEDIES  BEING
HEREIN  EXPRESSLY  WAIVED BY SELLER.  THE PAYMENT OF SUCH  AMOUNT AS  LIQUIDATED
DAMAGES IS NOT INTENDED AS A FORFEITURE OR PENALTY BUT IS INTENDED TO CONSTITUTE
LIQUIDATED  DAMAGES TO SELLER.  UPON DEFAULT BY BUYER,  THIS AGREEMENT  SHALL BE
TERMINATED,  AND  NEITHER  PARTY SHALL HAVE ANY  FURTHER  RIGHTS OR  OBLIGATIONS
HEREUNDER,  EACH TO THE OTHER  EXCEPT  FOR THE RIGHT OF SELLER TO  COLLECT  SUCH
LIQUIDATED  DAMAGES  FROM BUYER AND ESCROW  HOLDER.  NOTHING  CONTAINED  IN THIS
PARAGRAPH  SHALL LIMIT  SELLER'S  RIGHT TO RECOVER  ATTORNEYS  FEES AND COSTS IN
ENFORCING ITS RIGHTS UNDER THIS AGREEMENT.

      10.2 TO BUYER'S OBLIGATIONS.  If, at the Closing,  Seller is in default of
      any of its obligations  under this Agreement,  Buyer shall have the right,
      to elect, as its sole and exclusive remedy, to take one, but not more than
      one, of the following  actions:  (a) terminate  this  Agreement by written
      notice to Seller,  promptly  after which the Deposit  shall be returned to
      Buyer, and to recover the actual  out-of-pocket  expenses paid by Buyer to
      unrelated  third parties in  evaluating  the purchase of the Property in a
      total amount not to exceed Fifty Thousand Dollars ($50,000.00),  (b) waive
      the  default and  proceed to close the  Transaction  or (c) in lieu of (a)
      above bring an action  against  Seller for specific  performance.  Buyer's
      right to sue for  specific  performance  is  conditioned  upon the parties
      agreement that in order to sue for specific performance Buyer must forever
      waive any claim  against  Seller for  damages  for any breach of  Seller's
      obligations  hereunder (except as specifically  provided for below), Buyer
      will not be, in any such suit for  specific  performance,  entitled to any
      off-set or reduction in the Purchase Price,  Buyer must file any such suit
      for specific performance within ninety (90) days after Buyer becomes aware
      of the breach by Seller of its  obligations  hereunder  (and if Buyer does
      not file any such suit with such  ninety  (90) day period  Buyer  shall be
      deemed to have elected to have  terminated this  Agreement).  Seller shall
      not be  deemed to be in  default  under  this  Agreement  until  Buyer has
      provided Seller with a written notice specifying the default of Seller and
      Seller  has  failed  to cure  such  default  within  five (5)  days  after
      receiving such notice.  As a condition  precedent to Buyer  exercising any
      right it may have to bring an action to recover the  expenses  referred to
      above,  Buyer must not be in default under this Agreement,  and Buyer must
      commence an action to recover the expenses  within  ninety (90) days after
      the  occurrence  of  Seller's  default.  Buyer  agrees that its failure to
      timely commence such an action within such ninety (90) day period shall be
      deemed a waiver  by it of its right to  commence  such an  action.  In the
      event Buyer  timely  files and is  otherwise  entitled to sue for specific
      performance  hereunder,  Seller shall  reimburse  Buyer for its reasonable
      costs and  expenses  incurred by Buyer in  connection  with such  specific
      performance lawsuit.

                              CONDEMNATION/CASUALTY

      11.1 CONDEMNATION.

            11.1.1 Right to Terminate. If, prior to the Closing Date, all or any
            significant  portion (as  hereinafter  defined)  of the  Property is
            taken by eminent domain (or is the subject of a pending taking which
            has not yet been consummated),  Seller shall notify Buyer in writing
            of such  fact  promptly  after  obtaining  knowledge  thereof,  and,
            thereafter,  Buyer shall have the right to terminate  this Agreement
            by giving written notice to Seller no later than ten (10) days after
            the  giving  of  Seller's  notice,  and the  Closing  Date  shall be
            extended, if necessary, to provide sufficient time for Buyer to make
            such  election.  The  failure  by Buyer to so  elect in  writing  to
            terminate  this  Agreement  within such ten (10) day period shall be
            deemed an election to terminate this Agreement. For purposes hereof,
            a "significant portion" of the Property shall mean such a portion as
            shall have a value, as reasonably determined by Seller, in excess of
            ten  percent  (10%)  of the  Purchase  Price or  shall  result  in a
            termination  of the  Lease of the  Property,  or shall  result  in a
            reduction of the parking  spaces of the Property below the number of
            spaces  required by  applicable  Laws.  If Buyer elects to terminate
            this  Agreement as aforesaid,  the  provisions of Section 11.4 shall
            apply.

            11.1.2  Assignment  of  Proceeds.  If (a)  Buyer  does not  elect to
            terminate  this  Agreement as  aforesaid  if all or any  significant
            portion of the  Property is taken,  or (b) a portion of the Property
            not  constituting a significant  portion of the Property is taken or
            becomes subject to a pending taking, by eminent domain,  there shall
            be no abatement of the Purchase Price;  provided,  however, that, at
            the  Closing,  Seller shall pay to Buyer the amount of any award for
            or other proceeds on account of such taking which have been actually
            paid to Seller  prior to the Closing Date as a result of such taking
            (less all reasonable costs and expenses,  including  attorneys' fees
            and costs,  incurred by Seller as of the Closing  Date in  obtaining
            payment of such award or proceeds)  and, to the extent such award or
            proceeds  have not been paid,  Seller  shall  assign to Buyer at the
            Closing  (without  recourse  to Seller) the rights of Seller to, and
            Buyer shall be  entitled  to receive and retain,  all awards for the
            taking of the Property or such portion thereof.

      11.2 DESTRUCTION OR DAMAGE. In the event any of the Property is damaged or
      destroyed prior to the Closing Date,  Seller shall notify Buyer in writing
      of such fact  promptly  after  obtaining  knowledge  thereof.  If any such
      damage or destruction:  (i) (a) is an insured  casualty and (b) would cost
      less than an amount equal to ten percent  (10%) of the  Purchase  Price to
      repair or restore, and (ii) does not result in a termination of the Lease,
      then this Agreement  shall remain in full force and effect and Buyer shall
      acquire the Property upon the terms and conditions  set forth herein.  The
      cost of repair shall be determined by an architect and contractor selected
      by Seller and  reasonably  approved by Buyer.  In such event,  Buyer shall
      receive a credit against the Purchase Price equal to the deductible amount
      applicable  under  Seller's  casualty  policy less all costs and expenses,
      including reasonable  attorneys' fees and costs,  incurred by Seller as of
      the Closing Date in connection with the negotiation  and/or  settlement of
      the  casualty  claim with the insurer  ("REALIZATION  Costs"),  and Seller
      shall assign to Buyer all of Seller's right,  title and interest in and to
      all proceeds of insurance on account of such damage or destruction. In the
      event the Property is damaged or  destroyed  prior to the Closing Date and
      the cost of repair  would  equal or exceed an amount  equal to ten percent
      (10%) of the Purchase  Price,  or the  casualty is an uninsured  casualty,
      then,  notwithstanding  anything to the  contrary  set forth above in this
      section,  Buyer shall have the right,  at its election,  to terminate this
      Agreement.  Buyer shall have ten (10) days after Seller  notifies Buyer of
      the cost of  repairing  the damage to make such  election  by  delivery to
      Seller of a written  election notice  ("ELECTION  NOTICE") and the Closing
      Date shall be extended, if necessary, to provide sufficient time for Buyer
      to make such election. The failure by Buyer to deliver the Election Notice
      within such ten (10) day period  shall be deemed an election to  terminate
      this Agreement.  Notwithstanding  anything  contained in Section 7.1(d) to
      the contrary,  any  termination by Buyer under this Section 11.2 shall not
      result  in a  termination  of  Buyer's  right  to  acquire  any  remaining
      Portfolio  Properties under the Portfolio  Agreements.  In the event Buyer
      does not  elect to  terminate  this  Agreement  as set forth  above,  this
      Agreement  shall  remain in full force and effect,  Seller shall assign to
      Buyer all of  Seller's  right,  title and  interest  in and to any and all
      proceeds of  insurance on account of such damage or  destruction,  if any,
      and, if the casualty was an insured casualty, Buyer shall receive a credit
      against  the  Purchase  Price  equal to the  deductible  amount  (less the
      Realization Costs) under Seller's casualty insurance policy.

      11.3  INSURANCE.  Seller shall  maintain the property  insurance  coverage
      currently in effect for the Property through the Closing Date.

      11.4 EFFECT OF  TERMINATION.  If this Agreement is terminated  pursuant to
      Section 11.1 or Section 11.2, the Deposit shall be returned to Buyer. Upon
      such refund,  this  Agreement  shall  terminate  and neither party to this
      Agreement  shall have any further  rights or obligations  hereunder  other
      than any arising under any section herein which expressly provides that it
      shall survive the termination of this Agreement.

      11.5 WAIVER. The provisions of this Article 11 supersede the provisions of
      any applicable Laws with respect to the subject matter of this Article 11.

                                   ARTICLE 12
                                     ESCROW

The Deposit  and any other sums which the parties  agree shall be held in escrow
(herein  collectively called the "ESCROW DEPOSITS"),  together with all interest
earned  thereon,  shall be held by the Escrow Agent,  in trust,  and disposed of
only in accordance with the following provisions:

                  (a) The Escrow  Agent  shall  invest the  Escrow  Deposits  in
government insured  interest-bearing  instruments satisfactory to both Buyer and
Seller,  shall not  commingle  the Escrow  Deposits with any funds of the Escrow
Agent or others,  and shall promptly provide Buyer and Seller with  confirmation
of the investments made.

<PAGE>

                  (b) The party  entitled  to the  Deposit  shall pay any income
taxes on any interest earned on the Escrow Deposits.

                  (c) This  Agreement  shall  constitute  Escrow  Agent's escrow
instructions.  Buyer and Seller  shall  execute  and return to Escrow  Agent any
additional  standard escrow  instructions  Escrow Agent reasonably requests that
Buyer and Seller execute within two (2) business days after they are received by
Buyer and Seller. To the extent of any conflict between the terms and conditions
of this Agreement and Escrow Agent's standard escrow instructions,  the terms of
this Agreement shall control.

                                   ARTICLE 13
                                 LEASING MATTERS

      13.1 CERTAIN  DEFINITIONS.  For purposes of this Agreement,  the following
      terms shall have the following meanings:

      "EXECUTION  DATE"  shall  mean the date that both  Buyer and  Seller  have
      executed this Agreement.

      "PRE-EXECUTION  LEASES" shall mean,  collectively,  any lease for space at
      the  Property  executed  by the  landlord  and the tenant on or before the
      Execution Date.

      13.2  LEASE  MODIFICATIONS.  After  the  Execution  Date and  prior to the
      expiration of the Due Diligence Period,  Seller shall not, without Buyer's
      prior  written  consent  in each  instance,  which  consent  shall  not be
      unreasonably  withheld and shall be given or denied,  with the reasons for
      such denial specified in reasonable detail,  within five (5) business days
      after  receipt  by  Buyer  of the  information  referred  to in  the  next
      sentence,  (a) modify or amend any Pre-Execution Lease (except pursuant to
      the exercise by a tenant of a renewal,  extension  or expansion  option or
      other  right  contained  in  such  tenant's  lease);  (b)  consent  to any
      assignment or sublease in connection with any Pre-Execution  Lease; or (c)
      remove  any  tenant  under any  Pre-Execution  Lease,  whether  by summary
      proceedings  or  otherwise,  (the matters set forth in  subparagraphs  (a)
      through (c) above are collectively referred to as a "Lease Modification").
      Seller shall  furnish Buyer with a written  notice of the proposed  action
      which shall  contain  information  regarding  the proposed  action that is
      reasonably  necessary  to enable  Buyer to make  informed  decisions  with
      respect  to  the  advisability  of  the  proposed  action  including,   if
      available,  any  draft  renewal,  extension,   amendment,   assignment  or
      sublease.  If Buyer fails to object in writing to any such proposed action
      within  five  (5)  business  days  after  receipt  of  the  aforementioned
      information,  Buyer shall be deemed to have approved the proposed  action.
      If any Lease  requires  that the  landlord's  consent  be given  under the
      applicable  circumstances,  then Buyer  shall be deemed ipso facto to have
      approved such action.  Any notice from Buyer rejecting the proposed action
      shall include a description of the reasons for Buyer's rejection. If Buyer
      rejects the proposed action,  Seller shall nevertheless retain full right,
      power and  authority to execute such  documents as are necessary to effect
      such action,  and Seller  shall  promptly  advise  Buyer of the same.  The
      foregoing  notwithstanding,  in the event Buyer has  rejected the proposed
      action but Seller nonetheless  proceeds to effect it, Buyer shall have the
      right, within five (5) business days after receipt of Seller's notice that
      Seller has taken such action,  to elect to terminate this Agreement by the
      delivery to Seller of a written notice of  termination,  in which case the
      Deposit shall be paid to Buyer and, thereafter,  the parties shall have no
      further rights or obligations  hereunder  other than any arising under any
      section  herein  which  expressly  provides  that  it  shall  survive  the
      termination of this Agreement. If Buyer fails to notify Seller within such
      time  period,  Buyer  shall be deemed to have  fully  waived any rights to
      terminate  this  Agreement  pursuant to this  Section  13.2.  Seller shall
      deliver  to  Buyer  a true  and  complete  copy of each  such  renewal  or
      extension  agreement,  modification,  or  amendment,  as the  case may be,
      promptly after the execution and delivery thereof. After the expiration of
      the Due Diligence Period,  Seller shall not, without Buyer's prior written
      consent,  which consent may be withheld in Buyer's sole discretion,  enter
      into any Lease  Modification.  Seller shall  furnish  Buyer with a written
      notice of the  proposed  Lease  Modification.  If Buyer fails to object in
      writing to such proposed Lease Modification within three (3) business days
      after  receipt of such notice,  Buyer shall be deemed to have rejected the
      proposed Lease  Modification.  After the Execution Date, Seller shall not,
      without Buyer's prior written consent,  in Buyer's sole discretion,  enter
      into any additional leases affecting the Property.

      13.3 LEASE  ENFORCEMENT.  Subject to the provisions of Section 13.2 above,
      prior to the  Closing  Date,  Seller  shall  have the  right,  but not the
      obligation,  to enforce the rights and remedies of the landlord  under any
      Pre-Execution  Lease,  by summary  proceedings  or  otherwise  (including,
      without limitation,  the right to remove any tenant),  and to apply all or
      any portion of any security  deposits  then held by Seller toward any loss
      or damage incurred by Seller by reason of any defaults by tenants, and the
      exercise of any such rights or remedies  shall not affect the  obligations
      of  Buyer  under  this  Agreement  in any  manner  or  entitle  Buyer to a
      reduction in, or credit or allowance  against,  the Purchase Price or give
      rise to any other claim on the part of Buyer.

                                   ARTICLE 14
                                  MISCELLANEOUS

      14.1  BUYER'S  ASSIGNMENT.  Buyer shall not assign this  Agreement  or its
      rights  hereunder to any  individual  or entity  without the prior written
      consent of Seller,  which consent Seller may grant or withhold in its sole
      discretion,  and any such  assignment  shall  be null and void ab  initio;
      provided, however, Buyer shall be permitted to assign its rights hereunder
      upon  notice to, but  without  the  consent of Seller,  to a wholly  owned
      subsidiary  of  Buyer.  If  Seller  consents  to  an  assignment  of  this
      Agreement, as a condition to Buyer's right to assign this Agreement, Buyer
      and the  assignee  shall  deliver to Seller a written  agreement in a form
      reasonably acceptable to Seller executed by Buyer and the assignee whereby
      Buyer's  obligations  under this  Agreement are assigned to and assumed by
      the assignee,  and the assignee agrees to be bound by all of the terms and
      conditions of this  Agreement as if the assignee had  originally  executed
      this Agreement ("ASSIGNMENT AGREEMENT").  In the Assignment Agreement, the
      assignee  shall also  acknowledge  receipt of all Due  Diligence and other
      information received or obtained by Buyer. An assignment of this Agreement
      shall not relieve Buyer of its obligations hereunder.

      14.2 DESIGNATION AGREEMENT.  Section 6045(e) of the United States Internal
      Revenue  Code  and  the   regulations   promulgated   thereunder   (herein
      collectively called the "REPORTING  REQUIREMENTS")  require an information
      return to be made to the United States  Internal  Revenue  Service,  and a
      statement to be furnished to Seller, in connection with the Transaction.

                                       13
<PAGE>

                  (a)  Escrow  Agent  is  hereby  designated  as the  "REPORTING
PERSON" (as defined in the Reporting  Requirements) for the Transaction.  Escrow
Agent shall perform all duties that are required by the  Reporting  Requirements
to be performed by the Reporting Person for the Transaction.

                  (b)  Seller and Buyer  shall  furnish  to Escrow  Agent,  in a
timely  manner,  any  information  requested by Escrow Agent and  necessary  for
Escrow Agent to perform its duties as Reporting Person for the Transaction.

      14.3  SURVIVAL/MERGER.  Except for the provisions of this Agreement  which
      are  explicitly  stated to survive the  Closing,  (a) none of the terms of
      this Agreement shall survive the Closing, and (b) the delivery of the Deed
      and any other  documents  and  instruments  by Seller  and the  acceptance
      thereof by Buyer shall effect a merger, and be deemed the full performance
      and  discharge of every  obligation  on the part of Buyer and Seller to be
      performed hereunder.

      14.4  INTEGRATION;  WAIVER.  This  Agreement,  together  with the Exhibits
      hereto,  embodies and  constitutes  the entire  understanding  between the
      parties  with  respect  to  the  Transaction  and  all  prior  agreements,
      understandings,  representations  and  statements,  oral or  written,  are
      merged into this  Agreement.  Neither  this  Agreement  nor any  provision
      hereof may be waived, modified,  amended,  discharged or terminated except
      by an instrument  signed by the party against whom the enforcement of such
      waiver, modification,  amendment,  discharge or termination is sought, and
      then only to the extent set forth in such instrument.  No waiver by either
      party  hereto of any  failure or refusal by the other party to comply with
      its  obligations  hereunder  shall  be  deemed a  waiver  of any  other or
      subsequent failure or refusal to so comply.

      14.5 GOVERNING LAW. This Agreement  shall be governed by, and construed in
      accordance with, the law of the State where the Property is located.

      14.6 CAPTIONS NOT BINDING;  EXHIBITS.  The captions in this  Agreement are
      inserted for  reference  only and in no way define,  describe or limit the
      scope or intent of this Agreement or of any of the provisions  hereof. All
      Exhibits  attached hereto shall be incorporated by reference as if set out
      herein in full.

      14.7 BINDING EFFECT.  This Agreement shall be binding upon and shall inure
      to the benefit of the parties hereto and their  respective  successors and
      permitted assigns.

      14.8  SEVERABILITY.  If any term or  provision  of this  Agreement  or the
      application thereof to any persons or circumstances  shall, to any extent,
      be  invalid or  unenforceable,  the  remainder  of this  Agreement  or the
      application  of such term or provision to persons or  circumstances  other
      than those as to which it is held  invalid or  unenforceable  shall not be
      affected  thereby,  and each term and provision of this Agreement shall be
      valid and enforced to the fullest extent permitted by law.

      14.9 NOTICES. Any notice,  request,  demand,  consent,  approval and other
      communications  under this  Agreement  shall be in  writing,  and shall be
      deemed  duly  given or made at the time and on the date when  received  by

      receipt therefor (which shall include delivery by a nationally  recognized

      14.10 COUNTERPARTS.  This Agreement may be executed in counterparts,  each
      of which shall be an original and all of which counterparts taken together
      shall constitute one and the same agreement.

      14.11 NO  RECORDATION.  Seller and Buyer each  agrees  that  neither  this
      Agreement nor any  memorandum or notice hereof shall be recorded and Buyer
      agrees (a) not to file any notice of pendency or other  instrument  (other
      than a judgment) against the Property or any portion thereof in connection
      herewith  and (b) to  indemnify  Seller  against all costs,  expenses  and
      damages,  including,  without limitation,  reasonable  attorneys' fees and
      disbursements, incurred by Seller by reason of the filing by Buyer of such

      14.12 ADDITIONAL AGREEMENTS;  FURTHER ASSURANCES. Subject to the terms and
      conditions  herein provided,  each of the parties hereto shall execute and
      deliver  such  documents  as the other party shall  reasonably  request in
      order to consummate and make effective the Transaction; provided, however,
      that the execution and delivery of such  documents by such party shall not
      result in any additional liability or cost to such party.

      14.13  CONSTRUCTION.  The  parties  acknowledge  that  each  party and its
      counsel have reviewed and revised this  Agreement and that the normal rule
      of  construction  to the effect  that any  ambiguities  are to be resolved

      agrees  to pay any and all  costs  arising  as a result  of said  default,
      including reasonable attorneys' fees.

      event or condition is required by the terms of this  Agreement to occur or
      be  fulfilled  on a day which is not a business  day,  such  period  shall
      expire or such event or condition shall occur or be fulfilled, as the case
      may be, on the next succeeding business day.

      14.16 SELLER'S MAXIMUM AGGREGATE LIABILITY.  Notwithstanding any provision
      to the contrary  contained in this Agreement or any documents  executed by
      Seller pursuant hereto or in connection  herewith,  the maximum  aggregate
      liability of Seller, and the maximum aggregate amount which may be awarded
      to and collected by Buyer,  in connection  with the  Transaction and under
      this Agreement  (including,  without  limitation,  in connection  with the
      breach of any representations and warranties contained herein) and any and
      all documents executed pursuant hereto or in connection herewith for which
      a claim is timely  made by Buyer  shall not exceed Two  Hundred  and Fifty
      Thousand  and  No/100  Dollars  ($250,000.00);   and  provided,  shall  be
      actionable by the Buyer only if Buyer's  aggregate  damages resulting from
      the breach are  reasonably  estimated to exceed an amount in excess of One
      Hundred Thousand and No/100 ($100,000.00)  Dollars;  and provided,  Seller
      shall not be liable  for the  initial  One  Hundred  Thousand  and  No/100
      ($100,000.00)  Dollars in damages resulting from the breach.  Seller shall
      only have  liability  for the amount by which  Buyer's  aggregate  damages
      resulting  from  the  breach  exceed  One  Hundred   Thousand  and  No/100
      ($100,000.00), and in no manner shall Seller's maximum aggregate liability
      exceed Two Hundred and Fifty  Thousand and no/100  Dollars  ($250,000.00).
      The  provisions  of this  section  shall  survive the Closing  (and not be
      merged therein) or any earlier termination of this Agreement.

      14.17 1031  EXCHANGE.  Buyer may  acquire or Seller may sell the  Property
      through a tax-free  exchange  under  Section 1031 of the Internal  Revenue
      Code. In connection therewith, each party agrees to execute such documents
      as are reasonably  necessary or appropriate  and otherwise  cooperate with
      the other to effectuate  such  exchange;  provided the other party and its
      representatives shall have a reasonable opportunity to review all relevant
      documents prior to Closing. Seller hereby indemnifies and holds Buyer free
      and harmless  from any liability  (including,  but not limited to, the tax
      ramifications to the Seller of such tax-free  exchange)  arising by reason
      of  performing  the  acts  required  hereby  to  effectuate  the  Seller's
      exchange,  except insofar as any such  liabilities are attributable to the
      failure  of the Buyer to  perform  as  required  hereunder.  Buyer  hereby
      indemnifies  and holds the Seller  free and  harmless  from any  liability
      (including, but not limited to, the tax ramifications to the Buyer of such
      tax-free exchange) arising by reason of performing acts required hereby to
      effectuate the Buyer's  exchange,  except insofar as any such  liabilities
      are  attributable  to the  failure of the  Seller to  perform as  required
      hereunder.  No party shall be required to take title or  otherwise  assume
      any liability with respect to any property other than the Property.

      FOR VALUE RECEIVED,  the  undersigned,  CLF FBI BIRMINGHAM LLC, a Delaware
limited liability  company  ("Maker"),  having an address c/o Caplease,  LP, 110
Maiden Lane, 36th Floor, New York, New York 10005,  promises to pay to the order
of  WACHOVIA  BANK,  NATIONAL   ASSOCIATION,   a  national  banking  association
("PAYEE"),  at the office of Payee at  Commercial  Real  Estate  Services,  8739
Research Drive URP - 4, NC 1075,  Charlotte,  North Carolina  28262,  or at such
other place as Payee may  designate to Maker in writing  from time to time,  the
principal  sum of Eighteen  Million Eight  Hundred  Thousand and No/100  Dollars
($18,800,000.00),  together  with interest on so much thereof as is from time to
time  outstanding  and  unpaid,  from the date of the  advance of the  principal
evidenced hereby, at the Note Rate (as hereinafter  defined),  together with all
other  amounts  due  hereunder  or under the other Loan  Documents  (as  defined
herein),  in lawful  money of the United  States of America,  which shall at the
time of  payment be legal  tender in  payment of all debts and dues,  public and
private.  This promissory note shall be hereinafter  referred to as the "A Note"
and the loan evidenced by this A Note shall be hereinafter referred to as the "A
Loan".  Concurrently  with the execution of this A Note,  Maker has executed and
delivered to Caplease,  LP that certain promissory note dated the date hereof in
the original principal amount of Two Million One Hundred  Thirty-Seven  Thousand
Two Hundred Seventy-Six and 54/100 Dollars ($2,137,276.54),  which note shall be
hereinafter  referred  to as the "B Note" and the loan  evidenced  by the B Note
shall be hereinafter referred to as the "B Loan". The indebtedness  evidenced by
the B Note and the obligations  created thereby are also secured by the Security
Instrument  (as  hereinafter  defined),   the  Assignment  (as  defined  in  the
hereinafter defined Loan Documents) and the other Loan Documents (as hereinafter
defined)  securing  the A Loan.  Payee has been engaged as  collateral  agent by
Payee and the holder of the B Note to administer  the  documents and  collateral
securing this A Note and the B Note, including, without limitation, the Security
Property (as hereinafter defined). Maker shall make separate monthly payments of
principal  and  interest  under the A Note and the B Note,  as  directed  by the
holder of this A Note and the  holder  of the B Note.  The A Loan and the B Loan
shall be hereinafter referred to collectively as the "Loan".

                        ARTICLE I. - TERMS AND CONDITIONS

      1.1.  Note Rate.  The term "NOTE RATE" as used in this Note shall mean (a)
from the date of this Note through but not  including  the  Optional  Prepayment
Date (as hereinafter  defined),  a rate per annum equal to five and twenty-three
one hundredths  percent (5.23%) (the "INITIAL INTEREST RATE"),  and (b) from the
Optional  Prepayment  Date through and  including  the date this Note is paid in
full,  a rate per annum equal to the greater of (i) the  Initial  Interest  Rate
plus two and  one-half  percent  (2.5%) or (ii) the Treasury  Constant  Maturity
Yield Index (as hereinafter  defined) plus two and one-half  percent (2.5%) ((i)
or (ii),  as  applicable,  the "REVISED  INTEREST  RATE").  For purposes of this
Section 1.1, the term  "TREASURY  CONSTANT  MATURITY YIELD INDEX" shall mean the
average  yield for "This  Week" as  reported  by the  Federal  Reserve  Board in
Federal  Statistical  Release H.15 (519)  published  during the second full week
preceding  the  Optional  Prepayment  Date,  for  instruments  having a maturity
coterminous  with the  remaining  term of this  Note.  If  there is no  Treasury
Constant Maturity Yield Index for instruments having a maturity coterminous with
the remaining  term of this Note,  then the index shall be equal to the weighted
average yield to maturity of the Treasury  Constant  Maturity Yield Indices with
maturities next longer and shorter than such remaining average life to maturity,
calculated by averaging  (and rounding  upward to the nearest whole  multiple of
1/100 of 1% per annum,  if the average is not such a multiple) the yields of the
relevant Treasury Constant Maturity Yield Indices (rounded, if necessary, to the
nearest 1/100 of 1% with any figure of 1/200 of 1% or above rounded upward).  If
such Release is not available or no longer published, Payee may refer to another
recognized source of financial market information.

      1.2.  Computation of Interest.  Interest shall be computed hereunder based
on a 360-day year and based on the actual  number of days elapsed for any period
in which  interest  is  being  calculated  including,  without  limitation,  the
Interest Only Period  (hereinafter  defined),  as more particularly set forth on
Annex 1 attached  hereto and  incorporated  by this  reference.  Interest  shall
accrue from the date on which funds are advanced  hereunder  (regardless  of the
time of day) through and including the day on which funds are credited  pursuant
to Section 1.3 hereof.

      1.3.  Payment  of  Principal  and  Interest.  Payments  in  federal  funds
immediately  available  at the place  designated  for payment  received by Payee
prior to 2:00 p.m.  local time on a day on which  Payee is open for  business at
said place of payment shall be credited prior to close of business,  while other
payments,  at the  option  of  Payee,  may  not be  credited  until  immediately
available to Payee in federal funds at the place designated for payment prior to
2:00  p.m.  local  time on the  next day on  which  Payee is open for  business.
Interest  only  shall  be  payable  in  forty-eight  (48)  consecutive   monthly
installments  in the amount set forth on Annex 1,  beginning on October 11, 2005
(the "FIRST PAYMENT  DATE"),  and continuing on the eleventh  (11th) day of each
and every calendar  month  thereafter  through and including  September 11, 2009
(the  "INTEREST ONLY PERIOD") and,  thereafter,  principal and interest shall be
payable in seventy-two (72) consecutive  monthly  installments in the amount set
forth on Annex 1,  beginning on October 11, 2009 and  continuing on the eleventh
(11th) day of each and every  calendar  month  thereafter  through and including
August 11, 2015 (each, a "PAYMENT  DATE").  On September 11, 2015 (the "MATURITY
DATE" or the  "OPTIONAL  PREPAYMENT  DATE"),  the entire  outstanding  principal
balance hereof,  together with all accrued but unpaid interest thereon, shall be
due and payable in full; provided,  however, that in the event that such amounts
are not paid on such  date,  Payee  may,  at  Payee's  sole  option,  extend the
Maturity Date to September 11, 2039 (the "EXTENDED MATURITY DATE").

      Maker hereby  authorizes  Payee to use its automated loan payment  service
pursuant to which on each Payment Date Maker shall have its monthly  payments of
principal and interest  payments  together with any other sums then due to Payee
automatically  drawn by Payee or its  servicer in  accordance  with that certain
Auto-Draft  Request Form by and between  Maker and Payee  executed in connection
with the Loan.

<PAGE>

      In the event that, on any Payment Date,  there are  insufficient  funds in
such  account for sums due to Payee,  then Payee shall be  permitted to withdraw
sums from such account on any day thereafter until such time as all payments due
to Payee have been drawn from such  account;  provided,  however,  the foregoing
shall in no event limit or otherwise modify Maker's obligations to make payments
of principal  and interest and other sums due  hereunder or under any other Loan
Document.

      1.4.  Application  of  Payments.  So  long  as no  Event  of  Default  (as
hereinafter  defined)  exists  hereunder or under any other Loan Document,  each
such monthly  installment  shall be applied,  prior to the  Optional  Prepayment
Date, first, to any amounts  hereafter  advanced by Payee hereunder or under any
other  Loan  Document,  second,  to any late fees and other  amounts  payable to
Payee,  third,  to the  payment of accrued  interest  and last to  reduction  of
principal,  and from and after the  Optional  Prepayment  Date,  as  provided in
Section 2.2 of this Note.

      1.5.   Payment   of   "Short   Interest".   Maker   shall   pay  to  Payee
contemporaneously  with the  execution  hereof  interest  at the Note Rate for a
period from the date hereof through September 10, 2005.

      1.6. Prepayment; Defeasance.

            (a) This A Note may not be prepaid,  in whole or in part  (except as
otherwise  specifically  provided  herein),  at any time  prior to the  Optional
Prepayment  Determination  Date.  In the  event  that  Maker  wishes to have the
Security  Property  (as  hereinafter  defined)  released  from  the  lien of the
Security  Instrument (as hereinafter  defined) prior to the Optional  Prepayment
Determination  Date,  Maker's sole option shall be a Defeasance (as  hereinafter
defined)  upon  satisfaction  of the terms and  conditions  set forth in Section
1.6(d) hereof,  provided,  however,  that any Defeasance  under this A Note must
occur  simultaneously  with  the  Defeasance  of the B Note.  This A Note may be
prepaid in whole but not in part without  premium or penalty on any Payment Date
occurring on or after the Optional  Prepayment  Determination  Date provided (i)
written notice of such prepayment is received by Payee not more than ninety (90)
days and not less than  thirty  (30) days prior to the date of such  prepayment,
and (ii) such  prepayment  is  accompanied  by all  interest  accrued  hereunder
through  and  including  the  date of such  prepayment  and all  other  sums due
hereunder  or under  the  other  Loan  Documents.  If,  upon any such  permitted
prepayment  on any Payment Date  occurring  on or after the Optional  Prepayment
Determination  Date,  the  aforesaid  prior  written  notice has not been timely
received by Payee, there shall be due a prepayment fee equal to, an amount equal
to the lesser of (i) thirty (30) days' interest computed at the Note Rate on the
outstanding  principal  balance  of this A Note so  prepaid  and  (ii)  interest
computed at the Note Rate on the outstanding principal balance of this A Note so
prepaid  that would have been payable for the period from,  and  including,  the
date of prepayment  through the Maturity Date, or the Extended Maturity Date, as
the case may be, of this A Note as though such prepayment had not occurred.

            (b) If, prior to the fourth (4th)  anniversary  of the First Payment
Date (the "LOCKOUT EXPIRATION DATE"), the indebtedness  evidenced by this A Note
shall have been declared due and payable by Payee pursuant to Article III hereof
or the provisions of any other Loan Document due to a default by Maker, then, in
addition to the indebtedness  evidenced by this A Note being immediately due and
payable, there shall also then be immediately due and payable a sum equal to the
interest  which would have accrued on the principal  balance of this Note at the
Note Rate from the date of such  acceleration  to the Lockout  Expiration  Date,
together  with a  prepayment  fee in an amount  equal to the  Yield  Maintenance
Premium (as hereinafter defined) based on the entire indebtedness on the date of
such  acceleration.  If  such  acceleration  is  on  or  following  the  Lockout
Expiration  Date, the Yield  Maintenance  Premium shall also then be immediately
due and payable as though Maker were  prepaying the entire  indebtedness  on the
date of such  acceleration.  In  addition to the  amounts  described  in the two
preceding sentences,  in the event of any such acceleration or tender of payment
of  such  indebtedness  occurs  or is  made  on or  prior  to  the  first  (1st)
anniversary of the date of this Note,  there shall also then be immediately  due
and payable an additional  prepayment fee of three percent (3%) of the principal
balance  of this A Note.  The term  "YIELD  MAINTENANCE  PREMIUM"  shall mean an
amount equal to the greater of (A) two percent  (2.0%) of the  principal  amount
being  prepaid,  and (B) the present value of a series of payments each equal to
the Payment  Differential  (as hereinafter  defined) and payable on each Payment
Date over the remaining  original term of this A Note and on the Maturity  Date,
discounted at the Reinvestment Yield (as hereinafter  defined) for the number of
months remaining as of the date of such prepayment to each such Payment Date and
the Maturity Date. The term "PAYMENT DIFFERENTIAL" shall mean an amount equal to
(i) the Note Rate less the Reinvestment  Yield,  divided by (ii) twelve (12) and
multiplied  by (iii) the  principal  sum  outstanding  under  this A Note  after
application of the constant monthly payment due under this A Note on the date of
such  prepayment,  provided that the Payment  Differential  shall in no event be
less than zero. The term "REINVESTMENT  YIELD" shall mean an amount equal to the
lesser  of (i) the  yield on the U.S.  Treasury  issue  (primary  issue)  with a
maturity  date  closest  to the  Maturity  Date,  or (ii) the  yield on the U.S.
Treasury issue (primary  issue) with a term equal to the remaining  average life
of the  indebtedness  evidenced by this A Note, with each such yield being based
on the bid price for such issue as published  in the Wall Street  Journal on the
date that is  fourteen  (14) days prior to the date of such  prepayment  (or, if
such bid price is not published on that date,  the next  preceding date on which
such bid price is so published)  and converted to a monthly  compounded  nominal
yield.  In the event  that any  prepayment  fee is due  hereunder,  Payee  shall
deliver to Maker a statement  setting forth the amount and  determination of the
prepayment  fee,  and,  provided that Payee shall have in good faith applied the
formula  described  above,  Maker  shall  not have the  right to  challenge  the
calculation or the method of calculation  set forth in any such statement in the
absence of manifest  error,  which  calculation  may be made by Payee on any day
during the fifteen (15) day period preceding the date of such prepayment.  Payee
shall not be  obligated  or required  to have  actually  reinvested  the prepaid
principal  balance at the  Reinvestment  Yield or  otherwise  as a condition  to
receiving the prepayment fee.

            (c)  Partial  or  full  prepayments  of  this  A Note  shall  not be
permitted,  except  for  partial  or full  prepayments  resulting  from  Payee's
election to apply insurance or  condemnation  proceeds to reduce the outstanding
principal  balance of this A Note as provided  in the  Security  Instrument,  in
which event no  prepayment  fee or premium  shall be due unless,  at the time of
either Payee's  receipt of such proceeds or the  application of such proceeds to
the  outstanding  principal  balance of this A Note, an Event of Default,  or an
event which,  with notice or the passage of time, or both,  would  constitute an
Event of  Default,  shall have  occurred,  which  default or Event of Default is
unrelated  to the  applicable  casualty  or  condemnation,  in which  event  the
applicable  prepayment  fee or premium  shall be due and payable  based upon the
amount of the  prepayment.  No notice of prepayment  shall be required under the
circumstances  specified in the preceding  sentence.  No principal amount repaid
may be reborrowed. Any such partial prepayments of principal shall be applied to
the unpaid principal  balance  evidenced  hereby but such application  shall not
reduce the amount of the fixed monthly installments required to be paid pursuant
to Section 1.3 above.  Except as otherwise  expressly  provided in this Section,
the  prepayment  fees  provided  above shall be due, to the extent  permitted by
applicable law, under any and all

                                       2

circumstances where all or any portion of this A Note is paid prior to the
Maturity Date, whether such prepayment is voluntary or involuntary, including,
without limitation, if such prepayment results from Payee's exercise of its
rights upon Maker's default and acceleration of the Maturity Date of this A Note
(irrespective of whether foreclosure proceedings have been commenced), and shall
be in addition to any other sums due hereunder or under any of the other Loan
Documents. No tender of a prepayment of this A Note with respect to which a
prepayment fee is due shall be effective unless such prepayment is accompanied
by the applicable prepayment fee.

            Any  voluntary  prepayment or defeasance of the A Loan or the B Loan
must occur concurrently with the voluntary prepayment or defeasance of the other
Loan.  Unless  there  is a  continuing  Event  of  Default,  there  shall  be no
prepayment penalty or premium for prepayment resulting from application of title
insurance, casualty insurance or condemnation proceeds or awards.

            (d) (i) On any Payment  Date on or after the earlier to occur of (x)
the  Lockout  Expiration  Date,  and  (y)  the  later  to  occur  of (A) the day
immediately  following the date which is two (2) years after the "startup  day,"
within the meaning of Section 860G(a) (9) of the Internal  Revenue Code of 1986,
as amended from time to time or any successor  statute (the "CODE"),  of a "real
estate mortgage  investment  conduit," within the meaning of Section 860D of the
Code (a  "REMIC  TRUST"),  that  holds  this A Note and (B) the day  immediately
following  the date which is two (2) years after the "startup  day",  within the
meaning of Section 860G(a)(9) of the Code, of a "real estate mortgage investment
conduit," within the meaning of Section 860D of the Code, that holds the B Note,
and  provided no Event of Default  has  occurred  hereunder  or under any of the
other Loan Documents,  at Maker's  option,  Payee shall cause the release of the
Security  Property from the lien of the Security  Instrument  and the other Loan
Documents (a "DEFEASANCE") upon the satisfaction of the following conditions:

                  (A) Maker  shall give not more than  ninety (90) days' or less
            than sixty (60) days' prior written  notice to Payee  specifying the
            date  Maker  intends  for  the  Defeasance  to be  consummated  (the
            "RELEASE DATE"), which date shall be a Payment Date.

                  (B) All  accrued  and unpaid  interest  and all other sums due
            under  this A Note and  under  the other  Loan  Documents  up to and
            including  the Release Date shall be paid in full on or prior to the
            Release Date.

                  (C) Maker  shall  deliver to Payee on or prior to the  Release
            Date:

                  (1)   a sum of  money  in  immediately  available  funds  (the
                        "DEFEASANCE DEPOSIT") equal to the outstanding principal
                        balance  of this A Note plus an  amount,  if any,  which
                        together with the outstanding  principal balance of this
                        A Note, shall be sufficient to enable Payee to purchase,
                        through  means  and  sources  customarily  employed  and
                        available  to  Payee,  for the  account  of  Maker,  (x)
                        direct,  non-callable,  fixed  rate  obligations  of the
                        United States of America or (y) non-callable, fixed rate
                        obligations,  other than U.S. Treasury Obligations, that
                        are  "government   securities"  within  the  meaning  of
                        Section 2(a)(16) of the Investment  Company Act of 1940,
                        as amended,  that  provide for  payments  prior,  but as
                        close as possible,  to all  successive  monthly  Payment
                        Dates  occurring  after  the  Release  Date  and  to the
                        Maturity Date,  with each such payment being equal to or
                        greater than the amount of the corresponding installment
                        of principal  and/or interest  required to be paid under
                        this A Note (including,  but not limited to, all amounts
                        due on the  Maturity  Date) for the  balance of the term
                        hereof  (the  "DEFEASANCE  COLLATERAL"),  each of  which
                        shall be duly endorsed by the holder thereof as directed
                        by Payee  or  accompanied  by a  written  instrument  of
                        transfer in form and substance  satisfactory to Payee in
                        its sole discretion (including, without limitation, such
                        instruments   as  may  be  required  by  the  depository
                        institution   holding  such  securities  or  the  issuer
                        thereof,  as the case may be, to  effectuate  book-entry
                        transfers and pledges through the book-entry  facilities
                        of such  institution)  in  order  to  perfect  upon  the
                        delivery  of  the  Defeasance   Security  Agreement  (as
                        hereinafter   defined)  the  first   priority   security
                        interest in the Defeasance  Collateral in favor of Payee
                        in conformity with all applicable state and federal laws
                        governing granting of such security interests;

                  (2)   a pledge and security  agreement,  in form and substance
                        satisfactory   to  Payee,   creating  a  first  priority
                        security  interest  in favor of Payee in the  Defeasance
                        Collateral (the "DEFEASANCE SECURITY AGREEMENT");

                  (3)   a  certificate  of  Maker  certifying  that  all  of the
                        requirements set forth in this subsection 1.6(d)(i) have

                        substance  and  delivered  by  counsel  which  would  be
                        satisfactory to Payee stating,  among other things, that
                        (i)  Payee  has  a  perfected  first  priority  security
                        interest  in the  Defeasance  Collateral  and  that  the
                        Defeasance  Security  Agreement is  enforceable  against
                        Maker in accordance with its terms, (ii) in the event of
                        a  bankruptcy  proceeding  or  similar  occurrence  with
                        respect to Maker, none of the Defeasance  Collateral nor
                        any proceeds  thereof will be property of Maker's estate

                        amended,  or  any  similar  statute  and  the  grant  of
                        security  interest therein to Payee shall not constitute
                        an avoidable  preference  under  Section 547 of the U.S.
                        Bankruptcy  Code, as amended,  or applicable  state law,
                        (iii) the release of the lien of the Security Instrument
                        and  the  pledge  of  Defeasance   Collateral  will  not
                        directly  or  indirectly  result  in or cause  any REMIC
                        Trust that then  holds  this A Note to fail to  maintain
                        its status as a REMIC Trust and (iv) the defeasance will
                        not cause any REMIC Trust to be an "investment  company"
                        under the Investment Company Act of 1940;

                        (as defined in the  Security  Instrument)  to the effect
                        that the  Defeasance  will not result in a  downgrading,

                        with the  securitization  which  are  then  outstanding;
                        provided,  however,  no  evidence  from a Rating  Agency
                        shall  be  required  if this A Note  does  not  meet the
                        then-current review requirements of such Rating Agency;

                        Collateral,    including,    without   limitation,   all

                        assumption of the A Note, or  substitution of collateral
                        for the Security Property shall be paid on or before the
                        Release Date. Without limiting Maker's  obligations with
                        respect  thereto,  Payee shall be entitled to deduct all
                        such  fees,   costs,   expenses  and  charges  from  the
                        Defeasance  Deposit to the extent of any  portion of the

                        purchase the Defeasance Collateral.

                  (D) In connection  with the Defeasance  Deposit,  Maker hereby
            authorizes and directs Payee using the means and sources customarily
            employed  and  available to Payee to use the  Defeasance  Deposit to
            purchase  for  the  account  of  Maker  the  Defeasance  Collateral.
            Furthermore,  the Defeasance  Collateral shall be arranged such that
            payments  received  from such  Defeasance  Collateral  shall be paid
            directly  to Payee to be applied on account of the  indebtedness  of
            this A Note.  Any part of the  Defeasance  Deposit  in excess of the
            amount  necessary to purchase the  Defeasance  Collateral and to pay

            Section 1.6 shall be refunded to Maker.

                  (E)  The  Defeasance  of  the  A  Loan  must  occur  with  the
            simultaneous  Defeasance  of the B Loan subject to and in accordance
            with the terms of each such Loan.

                  (F) The following  conditions  shall be satisfied with respect
            to that certain loan (Loan No. 50-2852182) in the original principal

            LOAN") and that certain loan (Loan No.  50-2852180)  in the original
            principal  amount of  $11,280,000.00  by Payee to CLF DEA Birmingham

                  (1)   The  United   States  of   America  or  another   tenant
                        reasonably  acceptable to Payee having an unsecured debt
                        rating  of at least  BBB by  Standard  & Poor's  Ratings
                        Group and Baa2 by Moody's Investors Service,  Inc. shall
                        be in occupancy and paying unabated rent;

                  (2)   After the partial defeasance described in subsection (4)
                        below, the loan to value ratio shall be no more than 75%
                        and the debt service coverage ratio shall be no less
                        than 1.25:1.00, as determined by Payee in Payee's
                        reasonable discretion;

                  (3)   Twenty-five   percent  (25%)  of  the   then-outstanding
                        principal balance of the Promissory Notes evidencing the
                        SSA  Loan  and  the  DEA  Loan  shall  be   defeased  in
                        accordance with Section 1.6(e) and Section 1.6(f) of the
                        Promissory  Note  evidencing  the SSA  Loan  and the DEA
                        Loan.

                  (4)   No event of default shall have  occurred  under the loan
                        documents  evidencing  the SSA Loan and the DEA Loan and
                        remain uncured.

            (ii) Upon compliance with the requirements of subsection  1.6(d)(i),
      the  Security  Property  shall be released  from the lien of the  Security
      Instrument and the other Loan  Documents,  and the  Defeasance  Collateral
      shall  constitute  collateral which shall secure this A Note and all other
      obligations  under the Loan  Documents.  Payee will,  at Maker's  expense,
      execute  and  deliver  any  agreements  reasonably  requested  by Maker to
      release the lien of the Security Instrument from the Security Property.

            (iii) Upon the release of the Security  Property in accordance  with
      this Section  1.6(d),  Maker shall assign all its  obligations  and rights
      under this A Note, together with the pledged Defeasance  Collateral,  to a
      newly created  successor  entity which  complies with the terms of Section
      2.29 of the Security Instrument  designated by Maker and approved by Payee
      in its sole discretion.  Such successor entity shall execute an assumption
      agreement  in  form  and  substance  satisfactory  to  Payee  in its  sole
      discretion  pursuant to which it shall assume  Maker's  obligations  under
      this A Note and the Defeasance Security  Agreement.  As conditions to such
      assignment and assumption,  Maker shall (x) deliver to Payee an opinion of
      counsel  in form  and  substance  satisfactory  to a  prudent  lender  and
      delivered by counsel satisfactory to a prudent lender stating, among other
      things,  that such assumption  agreement is enforceable  against Maker and
      such  successor  entity in accordance  with its terms and that this A Note
      and the  Defeasance  Security  Agreement  as so assumed,  are  enforceable
      against such successor entity in accordance with their  respective  terms,
      and (y) pay all costs and expenses  (including,  but not limited to, legal
      fees) incurred by Payee or its agents in connection  with such  assignment
      and assumption (including,  without limitation, the review of the proposed
      transferee and the  preparation  of the  assumption  agreement and related
      documentation).  Upon such  assumption,  Maker  shall be  relieved  of its
      obligations  hereunder,  under  the other  Loan  Documents  other  than as
      specified  in  Section  1.6(d)(i)(C)(7)  above and  under  the  Defeasance
      Security Agreement (or other Defeasance document).

            (e) (i) In connection with the Defeasance of the SSA Loan or the DEA
            Loan,  provided no Event of Default  shall have  occurred and remain
            uncured, Maker shall have the right at any time after the earlier to
            occur  of (x)  four (4)  years  following  the  first  Payment  Date
            hereunder,  and (y) the day immediately  following the date which is
            two (2) years after the "startup day," within the meaning of Section
            860G(a) (9) of the Code of a REMIC Trust,  that holds this A Note to
            voluntarily    defease    twenty-five    percent    (25%)   of   the
            then-outstanding principal balance of this A Note by providing Payee
            with the  Partial  Defeasance  Collateral  (hereinafter,  a "Partial
            Defeasance  Event") upon  satisfaction  of the following  conditions
            precedent:

                        (A) Maker shall provide  Payee not less than  forty-five
                  (45) (but not more than ninety (90)) days notice (or a shorter
                  period of time if permitted  by Payee in its sole  discretion)
                  specifying a date (the "Partial Defeasance Date") on which the
                  Partial Defeasance Event is to occur.

                        (B)  Maker  shall  pay to  Payee  (x)  all  payments  of
                  principal  and interest due on the A Loan to and including the
                  Partial  Defeasance Date and (y) all other sums then due under
                  this A  Note,  the  Security  Instrument  and the  other  Loan
                  Documents;

                        (C)  Maker  shall   deposit   the   Partial   Defeasance
                  Collateral   (hereinafter   defined)   into   the   Defeasance
                  Collateral Account and otherwise comply with the provisions of
                  Section 1.6(f) hereof;

                        (D)  Payee  shall  prepare,  at  Maker's  sole  cost and
                  expense,  all necessary documents to modify, amend and restate
                  the A Note and issue two substitute  notes,  one note having a
                  principal  balance equal to  twenty-five  percent (25%) of the
                  then-outstanding   principal  balance  of  this  A  Note  (the
                  "Defeased  Note"),  and the  other  note  having  a  principal
                  balance  equal to the excess of (x) the unpaid  balance of the
                  original  principal  amount of the A Loan, over (y) the amount
                  of the Defeased  Note (the  "Undefeased  Note").  The Defeased
                  Note and Undefeased  Note shall have identical terms as this A
                  Note except for the  principal  balance;  and,  in  connection
                  therewith,  the amount due on each Payment Date and the amount
                  of each such payment applied to principal  thereafter shall be
                  divided  between the Defeased Note and the Undefeased  Note in
                  the same proportion as the unpaid  principal  balance (in each
                  case immediately  after the Partial  Defeasance  Event) of the
                  Defeased  Note and the  Undefeased  Note,  as the case may be,
                  bears  to  the  aggregate  principal  balance  due  under  the
                  Defeased Note and the Undefeased  Note  immediately  after the
                  Partial Defeasance Event. The Defeased Note and the Undefeased
                  Note shall be cross defaulted and cross collateralized  unless
                  the  Rating  Agencies  shall  require  otherwise  or  unless a
                  successor  entity  that  is  not  an  Affiliate  of  Maker  is
                  established pursuant to Section 1.6(d)(iii) hereof. A Defeased
                  Note may not be the subject of any further defeasance;

                        (E)  Maker   shall   execute  and  deliver  to  Payee  a
                  Defeasance  Security  Agreement  in respect of the  Defeasance
                  Collateral Account and the Partial Defeasance Collateral;

                        (F) Maker  shall  deliver to Payee an opinion of counsel
                  for Maker that is standard in commercial lending  transactions
                  and subject only to customary qualifications,  assumptions and
                  exceptions  opining,  among other things, that (1) Payee has a
                  perfected  first  priority  security  interest  in the Partial
                  Defeasance  Collateral and the Defeasance  Collateral  Account
                  and that the  Defeasance  Security  Agreement  is  enforceable
                  against Maker in accordance  with its terms,  (2) in the event
                  of a bankruptcy  proceeding or similar occurrence with respect
                  to Maker,  none of the Partial  Defeasance  Collateral nor any
                  proceeds  thereof  will be  property of Maker's  estate  under
                  Section 541 of the U.S. Bankruptcy Code or any similar statute
                  and the grant of security  interest therein to Payee shall not
                  constitute  an avoidable  preference  under Section 547 of the
                  U.S.  Bankruptcy Code or applicable  state law, (3) the pledge
                  of the  Partial  Defeasance  Collateral  will not  directly or
                  indirectly  result in or cause any REMIC Trust that then holds
                  the Note to fail to maintain its status as a REMIC Trust,  and
                  (4) the  defeasance  will not cause  any REMIC  Trust to be an
                  "investment company" under the Investment Company Act of 1940;

                        (G)  Maker  shall   deliver  to  Payee  a   No-Downgrade
                  Confirmation   (as  that  term  is  defined  in  the  Security
                  Instrument) with respect to such partial defeasance;

                        (H) Maker shall deliver to Payee a  certificate  in form
                  and scope  acceptable to Payee in its sole  discretion from an
                  accountant  which would be acceptable to a reasonably  prudent
                  payee certifying that the Defeasance  Collateral will generate
                  amounts  sufficient  to make all  payments  of  principal  and
                  interest  due  under  this A  Note  (including  the  scheduled
                  outstanding  principal  balance  of  the A  Loan  due  on  the
                  Maturity Date);

                        (I) Maker  shall pay all  costs  and  expenses  of Payee
                  incurred  in  connection  with the Partial  Defeasance  Event,
                  including Payee's reasonable attorneys' fees and expenses.

            No portion of the Security  Property shall be released in connection
      with such partial defeasance.

            (ii) [Reserved].

            (iii) Upon  compliance with the  requirements of Section  1.6(e)(i),
      the Partial Defeasance  Collateral shall constitute collateral which shall
      secure  the  Defeased  Note  and all  other  obligations  under  the  Loan
      Documents.

            (iv) Upon the  completion  of such partial  defeasance in accordance
      with this  Section,  Maker may elect to  assign,  or at  Payee's  sole and
      absolute  discretion,  Payee  may  require  Maker  to  assign,  all of its
      obligations and rights under the Defeased Note,  together with the pledged
      Partial Defeasance Collateral,  to a successor Maker. Such successor Maker
      shall execute an assignment and assumption agreement in form and substance
      satisfactory  to Payee in its sole and  absolute  discretion  pursuant  to
      which it shall assume Maker's  obligations under the Defeased Note and the
      Defeasance  Security  Agreement.  As  conditions  to such  assignment  and
      assumption,  Maker  shall (A)  deliver  to Payee one or more  opinions  of
      counsel in form and  substance  and  delivered  by counsel  which would be
      satisfactory  to a prudent payee  stating,  among other things,  that such
      assignment and assumption  agreement is enforceable  against Maker and the
      successor  Maker in accordance  with its terms and that the Defeased Note,
      the  Defeasance  Security  Agreement and the other Loan  Documents,  as so
      assigned and  assumed,  are  enforceable  against the  successor  Maker in
      accordance with their respective  terms, and opining to such other matters
      relating to successor Maker and its organizational  structure as Payee may
      require, and (B) pay all fees, costs and expenses incurred by Payee or its
      agents in  connection  with such  assignment  and  assumption  (including,
      without  limitation,  legal  fees and  expenses  and for the review of the
      proposed  transferee and the  preparation of the assignment and assumption
      agreement and related certificates, documents and instruments and any fees
      payable to any Rating  Agencies and their counsel in  connection  with the
      issuance of the confirmation  referred to in subsection  (e)(i)(G) above).
      Upon such  assignment  and  assumption,  Maker  shall be  relieved  of its
      obligations  hereunder,  under the Defeased Note and under the  Defeasance
      Security Agreement.

            (f) On or before the date on which  Maker  delivers  the  Defeasance
      Collateral  or  Partial  Defeasance  Collateral,  Maker  shall open at any
      institution  which would be  acceptable  to a prudent  payee acting in its
      reasonable  discretion the defeasance  collateral account (the "Defeasance
      Collateral Account"). The Defeasance Collateral Account shall contain only
      (i) Defeasance Collateral or Partial Defeasance Collateral,  and (ii) cash
      from interest and principal paid on the  Defeasance  Collateral or Partial
      Defeasance Collateral.  All cash from interest and principal payments paid
      on the Defeasance  Collateral or Partial  Defeasance  Collateral  shall be
      paid over to Payee on each  scheduled  payment  date and applied  first to
      accrued and unpaid  interest and then to principal.  Maker shall cause the
      institution  at which the  Defeasance  Collateral  or  Partial  Defeasance
      Collateral  is  deposited  to enter an  agreement  with  Maker and  Payee,
      satisfactory  to Payee  in its sole  discretion,  pursuant  to which  such
      institution  shall agree to hold and distribute the Defeasance  Collateral
      or Partial Defeasance Collateral in accordance with this A Note. The Maker
      or Successor  Maker,  as applicable,  shall be the owner of the Defeasance
      Collateral  Account and shall report all income  accrued on the Defeasance
      Collateral or Partial Defeasance  Collateral for federal,  state and local
      income tax purposes in its income tax return.  Maker shall prepay all cost
      and  expenses  associated  with  opening and  maintaining  the  Defeasance
      Collateral Account.  Payee shall not in any way be liable by reason of any
      insufficiency in the Defeasance Collateral Account.

            (g) For purposes herein,  "Partial Defeasance Collateral" shall mean
      direct  non-callable  obligations of the United States of America or other
      obligations  which are  "government  securities"  within  the  meaning  of
      Section 2(a)(16) of the Investment  Company Act of 1940, to the extent the
      applicable  Rating Agencies rating the Secondary  Market  Transaction have
      confirmed  in writing  that such  obligations  will not cause a downgrade,
      withdrawal or qualification of the initial, or, if higher, then applicable
      ratings of the Secondary  Market  Transaction,  that provide for (i) on or
      prior to,  but as close as  possible  to,  the  Business  Day  immediately
      preceding all scheduled  payments dates and, under the Defeased Note after
      the Partial Defeasance Date and up to and including the Maturity Date, and
      (ii) in amounts equal to or greater than the scheduled defeasance payments
      relating to such scheduled payment dates.

      1.7.  Security.  The  indebtedness  evidenced  by  this  A  Note  and  the
obligations  created  hereby are secured by,  among other  things,  that certain
Mortgage, Security Agreement and Fixture Filing (the "SECURITY INSTRUMENT") from
Maker to Payee, dated of even date herewith, covering the Security Property. The
Security Instrument,  together with this A Note and all other documents to or of
which Payee is a party or  beneficiary  now or hereafter  evidencing,  securing,
guarantying,  modifying  or  otherwise  relating to the  indebtedness  evidenced
hereby, are herein referred to collectively as the "LOAN DOCUMENTS".  All of the
terms and provisions of the Loan Documents are incorporated herein by reference.
Some of the Loan  Documents  are to be filed  for  record  on or about  the date
hereof in the appropriate public records.

         ARTICLE II. - OPTIONAL PREPAYMENT DATE/TRIGGER EVENT PROVISIONS

      2.1. Optional  Prepayment Date;  Trigger Event. The following  subsections
shall apply from and after July 11, 2015 (the "OPTIONAL PREPAYMENT DETERMINATION

Security  Agreement of even date

                                       6
<PAGE>

herewith between Maker and Payee (the "LOCK-BOX AGREEMENT"), after the
occurrence of a Trigger Event (as defined in the Lock-Box Agreement):

            (a)  Except  as  hereinafter  set  forth in  subsection  (e) of this
Section 2.1,  Maker shall be obligated to pay, and Payee shall  collect from the
Lock-Box  Account (as defined in the Lock-Box  Agreement) to the extent of funds
on  deposit  in such  account,  on each  Payment  Date  following  the  Optional
Prepayment  Determination  Date the  following  payments in the listed  order of
priority:

            (i) First,  the  payment  of the amount set forth in Section  1.3 of
            this A Note  (the  "MONTHLY  DEBT  SERVICE  PAYMENT  AMOUNT")  to be
            applied  first to the  payment of  interest  computed at the Initial
            Interest  Rate with the  remainder  applied to the  reduction of the
            outstanding principal balance of this A Note;

            (ii)  Second,  payments to the  Reserves (as defined in the Security
            Instrument)  in  accordance  with the  terms and  conditions  of the
            Security Instrument;

            (iii)  Third,  payments  to the  deposit  bank  selected by Payee to
            maintain the Lock-Box Account (the "DEPOSIT BANK") for any customary
            fees charged in accordance with the Lock-Box Agreement;

            (iv)  Fourth,  payments for monthly  Cash  Expenses (as  hereinafter
            defined),  less  management  fees  payable to  affiliates  of Maker,
            pursuant to the terms and conditions of the related  Approved Annual
            Budget (as hereinafter defined);

            (v)  Fifth,  payment  for  Extraordinary  Expenses  (as  hereinafter
            defined) approved by Payee, if any;

            (vi)  Sixth,  payments  of any  other  amounts  due  under  the Loan
            Documents; and

            (vii)  Lastly,  any excess  amounts  shall  remain on deposit in the
            Lock-Box Account.

            (b)  For  the  calendar  year  in  which  the  Optional   Prepayment
Determination  Date or any  Trigger  Event  occurs  and for each  calendar  year
thereafter,  Maker shall submit to Payee for Payee's written  approval an annual
budget  (an  "Annual  Budget")  not  later  than  (i)  the  Optional  Prepayment
Determination Date or the first Payment Date after the date on which any Trigger
Event   occurs  for  the  calendar   year  in  which  the  Optional   Prepayment
Determination Date or any Trigger Event occurs and (ii) sixty (60) days prior to
the commencement of each calendar year thereafter, in form satisfactory to Payee
setting forth in reasonable detail budgeted monthly operating income and monthly
operating  capital and other  expenses  for the Security  Property.  Each Annual
Budget shall contain, among other things,  limitations on management fees, third
party service fees and other expenses as Maker may reasonably  determine.  Payee
shall have the right to approve  such Annual  Budget and in the event that Payee
objects to the proposed  Annual  Budget  submitted by Maker,  Payee shall advise
Maker of such  objections  within  fifteen (15) days after receipt  thereof (and
deliver to Maker a reasonably detailed description of such objections) and Maker
shall,  within  three (3) days after  receipt of notice of any such  objections,
revise such Annual  Budget and  resubmit  the same to Payee.  Payee shall advise
Maker of any objections to such revised Annual Budget within ten (10) days after
receipt thereof (and deliver to Maker a reasonably detailed  description of such
objections)  and Maker  shall  revise the same in  accordance  with the  process
described in this  subsection  until Payee approves an Annual Budget,  provided,
however,  that if Payee shall not advise Maker of its objections to any proposed
Annual Budget within the  applicable  time period set forth in this  subsection,
then such proposed  Annual Budget shall be deemed  approved by Payee.  Each such
Annual  Budget   approved  by  Payee  in  accordance  with  terms  hereof  shall
hereinafter be referred to as an "Approved  Annual Budget." Until such time that
Payee  approves a proposed  Annual  Budget,  the most recently  Approved  Annual
Budget shall apply; provided, that such Approved Annual Budget shall be adjusted
to reflect  actual  increases  in real  estate  taxes,  insurance  premiums  and
utilities expenses.

            (c) In the event that Maker  must incur an  extraordinary  operating
expense or  capital  expense  not set forth in the  Approved  Annual  Budget (as
defined in the Security  Instrument)  or allotted for in any Reserve  (each,  an
"EXTRAORDINARY   EXPENSE"),  then  Maker  shall  promptly  deliver  to  Payee  a
reasonably  detailed  explanation  of such  proposed  Extraordinary  Expense for
Payee's approval.

            (d) For the purposes of this A Note, "CASH EXPENSES" shall mean, for
any period,  the operating  expenses for the operation  and  maintenance  of the
Security  Property as set forth in an Approved  Annual Budget to the extent that
such  expenses are actually  incurred by Maker  excluding  payments into the any
Reserve, or which shall be paid for out of, any Reserve.

            (e) Notwithstanding the other provisions of this Section 2.1, in the
event that, prior to the Optional Prepayment  Determination Date, Maker delivers
to Payee either (i) a written commitment (the  "COMMITMENT")for  the refinancing
of the loan evidenced by this A Note from a Qualified  Institutional  Lender (as
hereinafter  defined),  which  reasonably  provides for the consummation of such
refinance  prior to the Optional  Prepayment Date or (ii) other evidence in form
and substance satisfactory to Payee in its sole determination of Maker's ability
to refinance the loan evidenced by this A Note prior to the Optional  Prepayment
Date,  then,  solely in either such  event,  and  provided no Trigger  Event has
occurred,  the terms of Section 2.1(a), (b), (c) and (d) of this A Note shall be
inoperative;  provided,  however, that upon (x) the failure of such refinance to
be  consummated  in  accordance  with the terms of the  Commitment or such other
evidence, as applicable, (y) the termination of the Commitment for any reason or
(z) any adverse change in circumstances  with respect to Maker or any principals
of Maker, the Security Property, the proposed lender or otherwise, as determined
by Payee in its sole  determination,  which,  in  Payee's  reasonable  judgment,
significantly decreases the likelihood of such refinance being consummated prior
to the Optional  Prepayment Date, the terms of Section 2.1(a),  (b), (c) and (d)
of this A Note shall  immediately  become operative and Maker shall  immediately
comply with any of the terms  thereof  which,  except for the  operation of this
subsection  (e),  Maker  would   theretofore  have  been  obligated  to  comply.
"QUALIFIED  INSTITUTIONAL  LENDER" shall mean a financial  institution  or other
lender with a long term credit rating which is not less than  investment  grade.
The  determination  of whether  the  conditions  set forth in clause (i) or (ii)
above,  shall be made and notice of such  determination  shall be  delivered  to
Maker,  within ten (10) business days following Payee's receipt of the items set
forth in such clauses.

      2.2.  Failure to Pay Prior to Optional  Prepayment Date. In the event that
Maker does not prepay the entire principal  balance of this A Note and any other
amounts  outstanding  under this A Note or any of the other Loan Documents on or
prior to the Optional Prepayment Date, the provisions of Section 2.1(b), (c) and
(d) as set forth above shall remain in full force and effect,  and the following
subsections also shall apply:

            (a) From and after the  Optional  Prepayment  Date,  interest  shall
accrue on the unpaid principal  balance from time to time outstanding under this
A Note at the Revised  Interest Rate.  Interest  accrued at the Revised Interest
Rate and not paid  pursuant to this  Section 2.2 shall be deferred  and added to
the  principal  balance of this A Note and shall earn  interest  at the  Revised
Interest Rate to the extent  permitted by applicable law (such accrued  interest
is hereinafter referred to as "ACCRUED  INTEREST").  All of the unpaid principal
balance of this A Note,  including,  without  limitation,  any Accrued Interest,
shall be due and payable on the Extended Maturity Date.

            (b) Maker shall be obligated  to pay,  and Payee shall  collect from
the Lock-Box  Account to the extent of funds on deposit in such account,  on the
Optional  Prepayment  Date and on the eleventh (11th) day of each calendar month
thereafter to and including  the Extended  Maturity Date the following  payments
from the funds on deposit in the Lock-Box Account received on or before such day
in the listed order of priority:

            (i) First, the payment of the Monthly Debt Service Payment Amount to
            be applied first to the payment of interest  computed at the Initial
            Interest  Rate with the  remainder  applied to the  reduction of the
            outstanding principal balance of this A Note;

            (ii) Second,  payments to the Reserves in accordance  with the terms
            and conditions of the Security Instrument;

            (iii) Third, payments to the Deposit Bank any customary fees charged
            in accordance with the Lock-Box Agreement;

            (iv) Fourth,  payments for monthly Cash  Expenses,  less  management
            fees  payable  to  affiliates  of Maker,  pursuant  to the terms and
            conditions of the related Approved Annual Budget;

            (v) Fifth, payment for Extraordinary  Expenses approved by Payee, if
            any;

            (vi)  Sixth,  payments  to Payee of the balance of the funds then on
            deposit  in the  Lock-Box  Account  to be  applied  to (x) any other
            amounts due under the Loan Documents,  (y) Accrued  Interest and (z)
            the reduction of the  outstanding  principal  balance of this A Note
            until such principal balance is paid in full in whatever  proportion
            and priority as Payee may determine.

            (c)  Nothing in this  Article II shall  limit,  reduce or  otherwise
affect Maker's  obligations to make payments of the Monthly Debt Service Payment
Amount, payments to the Reserves and payments of other amounts due hereunder and
under the other Loan Documents,  whether or not Rents and Profits (as defined in
the Security Instrument) are available to make such payments.

      2.3.  Trigger  Event.  In the event that any  Trigger  Event  occurs,  the
provisions of Section  2.1(b),  (c) and (d) as set forth above and the following
subsections shall apply:

      (a) Maker shall be  obligated  to pay,  and Payee shall  collect  from the
Lock-Box  Account  to the extent of funds on  deposit  in such  account,  on the
eleventh  (11th) day of each calendar  month  thereafter  until all amounts owed
under the Loan Documents are paid in full, the following payments from the funds
on deposit in the Lock-Box  Account received on or before such day in the listed
order of priority:

            (i) First, the payment of the Monthly Debt Service Payment Amount to
      be  applied  first to the  payment of  interest  computed  at the  Initial
      Interest  Rate  with  the  remainder  applied  to  the  reduction  of  the

      by this  Note  until  released  in  accordance  with  Section  3(b) of the
      Lock-Box Agreement.

      (b) Nothing in this  Section 2.3 shall limit,  reduce or otherwise  affect
Maker's obligations to make payments of the Monthly Debt Service Payment Amount,
payments to the Reserves and payments of other  amounts due  hereunder and under
the other  Loan  Documents,  whether or not Rents (as  defined  in the  Security
Instrument) are available to make such payments.

                             ARTICLE III. - DEFAULT

                                       8
<PAGE>

      3.1. Events of Default;  Cross Default.  (a) It is hereby expressly agreed
that  should any  default  occur in the  payment of  principal  or  interest  as
stipulated  above and such  payment is not made on the date such payment is due,
or should any other default not be cured within any  applicable  grace or notice
period occur under any other Loan Document,  then an event of default (an "EVENT
OF DEFAULT") shall exist hereunder, and in such event the indebtedness evidenced
hereby, including all sums advanced or accrued hereunder or under any other Loan
Document, and all unpaid interest accrued thereon, shall, at the option of Payee
and without notice to Maker, at once become due and payable and may be collected
forthwith,  whether  or not  there  has  been a prior  demand  for  payment  and
regardless of the stipulated date of maturity.

            (b) A default  or Event of Default  under any of the Loan  Documents
delivered in connection with either the A Loan or the B Loan (as the term "Event
of Default" is defined in the Security  Instrument) shall constitute an Event of
Default under the other Loan Documents  delivered in connection  with the A Loan
and/or the B Loan.

      3.2. Late Charges.  In the event that any payment is not received by Payee
on the date when due (subject to any applicable grace period), then, in addition
to any default interest payments due hereunder,  Maker shall also pay to Payee a
late  charge  in an  amount  equal to five  percent  (5%) of the  amount of such
overdue payment.

      3.3.  Default  Interest  Rate.  So long as any  Event  of  Default  exists
hereunder,  regardless of whether or not there has been an  acceleration  of the
indebtedness   evidenced  hereby,  and  at  all  times  after  maturity  of  the
indebtedness  evidenced hereby (whether by acceleration or otherwise),  interest
shall accrue on the outstanding  principal balance of this A Note, from the date
due until the date  credited,  at a rate per annum equal to four percent (4%) in
excess of the Note  Rate,  or, if such  increased  rate of  interest  may not be
collected under  applicable  law, then at the maximum rate of interest,  if any,
which may be collected from Maker under  applicable  law (the "DEFAULT  INTEREST
RATE"), and such default interest shall be immediately due and payable.

      3.4. Maker's  Agreements.  Maker  acknowledges  that it would be extremely
difficult or  impracticable to determine  Payee's actual damages  resulting from
any late  payment or default,  and such late  charges and default  interest  are
reasonable  estimates  of those  damages and do not  constitute  a penalty.  The
remedies  of  Payee  in this A Note or in the  Loan  Documents,  or at law or in
equity,  shall  be  cumulative  and  concurrent,  and  may  be  pursued  singly,
successively or together, in Payee's discretion.

      3.5.  Maker to Pay  Costs.  In the  event  that  this A Note,  or any part
hereof, is collected by or through an  attorney-at-law,  Maker agrees to pay all
costs of collection, including, but not limited to, reasonable attorneys' fees.

      3.6.  Exculpation.  Notwithstanding  anything  in this A Note or the  Loan
Documents to the contrary,  but subject to the  qualifications  hereinbelow  set
forth, Payee agrees that:

            (a) Maker shall be liable upon the indebtedness evidenced hereby and
for the other  obligations  arising under the Loan  Documents to the full extent
(but only to the extent) of the security therefor, the same being all properties
(whether  real or  personal),  rights,  estates and interests now or at any time
hereafter  securing the payment of this A Note and/or the other  obligations  of
Maker under the Loan Documents (collectively, the "SECURITY PROPERTY");

            (b) if a default  occurs in the timely and proper  payment of all or
any part of such  indebtedness  evidenced  hereby or in the  timely  and  proper
performance  of the other  obligations  of Maker under the Loan  Documents,  any
judicial  proceedings  brought by Payee  against  Maker  shall be limited to the
preservation,  enforcement  and  foreclosure,  or any  thereof,  of  the  liens,
security titles, estates,  assignments,  rights and security interests now or at
any  time  hereafter  securing  the  payment  of this A Note  and/or  the  other
obligations of Maker under the Loan Documents,  and no attachment,  execution or
other  writ of  process  shall be  sought,  issued  or levied  upon any  assets,
properties  or funds of Maker  other than the  Security  Property,  except  with
respect to the liability described below in this section; and

            (c) in the event of a foreclosure  of such liens,  security  titles,
estates, assignments,  rights or security interests securing the payment of this
A Note  and/or  the other  obligations  of Maker  under the Loan  Documents,  no
judgment for any  deficiency  upon the  indebtedness  evidenced  hereby shall be
sought or obtained by Payee against Maker,  except with respect to the liability
described below in this section;  provided,  however, that,  notwithstanding the
foregoing provisions of this section, Maker shall be fully and personally liable
and subject to legal action (i) for proceeds paid under any  insurance  policies
(or paid as a result of any other claim or cause of action against any person or
entity) by reason of damage,  loss or  destruction  to all or any portion of the
Security Property,  to the full extent of such proceeds not previously delivered
to Payee,  but which,  under the terms of the Loan  Documents,  should have been
delivered to Payee,  (ii) for proceeds or awards resulting from the condemnation
or other  taking in lieu of  condemnation  of all or any portion of the Security
Property, to the full extent of such proceeds or awards not previously delivered
to Payee,  but which,  under the terms of the Loan  Documents,  should have been
delivered to Payee,  (iii) for all tenant security  deposits or other refundable
deposits  paid to or held by Maker or any other  person or entity in  connection
with leases of all or any portion of the Security Property which are not applied
in accordance with the terms of the applicable  lease or other  agreement,  (iv)
for rent and other  payments  received  from tenants  under leases of all or any
portion of the Security  Property  paid more than one (1) month in advance,  (v)
for rents,  issues,  profits and  revenues of all or any portion of the Security
Property received or applicable to a period after the occurrence of any Event of
Default or any event which,  with notice or the passage of time, or both,  would
constitute an Event of Default,  hereunder or under the Loan Documents which are
not  either  applied  to the  ordinary  and  necessary  expenses  of owning  and
operating the Security  Property or paid to Payee,  (vi) for waste  committed on
the  Security  Property,  damage  to the  Security  Property  as a result of the
intentional  misconduct or gross  negligence of Maker or any of its  principals,
officers,  general partners or members,  any guarantor,  any indemnitor,  or any
agent or  employee of any such  person,  or any removal of all or any portion of
the Security  Property in violation of the terms of the Loan  Documents,  to the
full  extent of the  losses or  damages  incurred  by Payee on  account  of such
occurrence,  (vii) for failure to pay any valid taxes,  assessments,  mechanic's
liens,  materialmen's  liens or other  liens  which  could  create  liens on any
portion of the Security Property which would be superior to the lien or security
title of the Security Instrument or the other Loan Documents, to the full extent
of the amount claimed by any such lien claimant except, with respect to any such
taxes or  assessments,  to the extent that funds have been  deposited with Payee
pursuant to the terms of the Security Instrument

                                       9
<PAGE>

specifically for the applicable taxes or assessments and not applied by Payee to
pay such taxes and assessments, (viii) for all obligations and indemnities of
Maker under the Loan Documents relating to Hazardous Substances (as defined in
the Security Instrument) or radon or compliance with environmental laws and
regulations to the full extent of any losses or damages (including those
resulting from diminution in value of any Security Property) incurred by Payee
as a result of the existence of such hazardous or toxic substances or radon or
failure to comply with environmental laws or regulations, and (ix) for fraud,
material misrepresentation or failure to disclose a material fact by Maker or
any of its principals, officers, general partners or members, any guarantor, any
indemnitor or any agent, employee or other person authorized or apparently
authorized to make statements, representations or disclosures on behalf of
Maker, any principal, officer, general partner or member of Maker, any guarantor
or any indemnitor, to the full extent of any losses, damages and expenses of
Payee on account thereof. References herein to particular sections of the Loan
Documents shall be deemed references to such sections as affected by other
provisions of the Loan Documents relating thereto. Nothing contained in this
section shall (1) be deemed to be a release or impairment of the indebtedness
evidenced by this A Note or the other obligations of Maker under the Loan
Documents or the lien of the Loan Documents upon the Security Property, or (2)
preclude Payee from foreclosing the Loan Documents in case of any default or
from enforcing any of the other rights of Payee except as stated in this
section, or (3) limit or impair in any way whatsoever (A) the Indemnity and
Guaranty Agreement (the "INDEMNITY AGREEMENT") or (B) the Environmental
Indemnity Agreement (the "ENVIRONMENTAL INDEMNITY AGREEMENT"), each of even date
herewith executed and delivered in connection with the indebtedness evidenced by
this A Note or release, relieve, reduce, waive or impair in any way whatsoever,
any obligation of any party to the Indemnity Agreement or the Environmental
Indemnity Agreement.

      Notwithstanding  the  foregoing,  the  agreement  of Payee  not to  pursue
recourse  liability  as set forth in this Section 3.6 SHALL BECOME NULL AND VOID
and shall be of no further  force and effect in the event of a default by Maker,
Indemnitor  (as defined in the  Security  Instrument)  or any  general  partner,
manager or managing member of Maker which is a Single-Purpose Entity (as defined
in the  Security  Instrument)  (if  any) of any of the  covenants  set  forth in
Section 2.9 or Section 2.29 of the Security Instrument (excluding,  however, the
covenants set forth in Sections 2.29(n) and (t)).

      Notwithstanding  anything  to the  contrary in this A Note,  the  Security
Instrument or any of the other Loan Documents, Payee shall not be deemed to have
waived any right which Payee may have under Section 506(a),  506(b),  1111(b) or
any other  provisions of the U.S.  Bankruptcy  Code to file a claim for the full
amount  of  the  indebtedness  evidenced  hereby  or  secured  by  the  Security
Instrument or any of the other Loan  Documents or to require that all collateral
shall  continue to secure all of the  indebtedness  owing to Payee in accordance
with this A Note, the Security Instrument and the other Loan Documents.

      All rights,  powers or remedies of  enforcement  available to Payee by the
terms of the Loan Documents may be exercised by Collateral Agent.

                        ARTICLE IV. - GENERAL CONDITIONS

      4.1.  No Waiver;  Amendment.  No failure to  accelerate  the  indebtedness
evidenced hereby by reason of default hereunder, acceptance of a partial or past
due payment,  or indulgences granted from time to time shall be construed (i) as
a novation of this A Note or as a reinstatement  of the  indebtedness  evidenced
hereby or as a waiver  of such  right of  acceleration  or of the right of Payee
thereafter  to insist upon strict  compliance  with the terms of this A Note, or
(ii) to prevent the  exercise of such right of  acceleration  or any other right
granted  hereunder or by any applicable  laws; and Maker hereby expressly waives
the benefit of any statute or rule of law or equity now  provided,  or which may
hereafter be provided,  which would produce a result  contrary to or in conflict
with the  foregoing.  No extension of the time for the payment of this A Note or
any installment due hereunder made by agreement with any person now or hereafter
liable  for the  payment of this A Note shall  operate  to  release,  discharge,
modify,  change or affect the  original  liability  of Maker  under this A Note,
either in whole or in part,  unless  Payee agrees  otherwise in writing.  This A
Note may not be changed  orally,  but only by an agreement in writing  signed by
the party  against  whom  enforcement  of any waiver,  change,  modification  or
discharge is sought.

      4.2.  Waivers.  Presentment  for  payment,  demand,  protest and notice of
demand, protest and nonpayment and all other notices are hereby waived by Maker.
Maker hereby further waives and  renounces,  to the fullest extent  permitted by
law, all rights to the benefits of any  moratorium,  reinstatement,  marshaling,
forbearance, valuation, stay, extension, redemption, appraisement, exemption and
homestead now or hereafter  provided by the  Constitution and laws of the United
States of America and of each state thereof, both as to itself and in and to all
of its property,  real and personal,  against the  enforcement and collection of
the obligations evidenced by this A Note or the other Loan Documents.

      4.3.  Limit  of  Validity.  The  provisions  of  this  A  Note  and of all
agreements  between Maker and Payee,  whether now existing or hereafter  arising
and whether written or oral, including,  but not limited to, the Loan Documents,
are hereby  expressly  limited so that in no  contingency  or event  whatsoever,
whether by reason of demand or  acceleration  of the  maturity of this A Note or
otherwise,  shall the amount contracted for, charged,  taken, reserved,  paid or
agreed to be paid ("INTEREST") to Payee for the use, forbearance or detention of
the money loaned under this A Note exceed the maximum amount  permissible  under
applicable law. If, from any circumstance whatsoever, performance or fulfillment
of any provision  hereof or of any agreement  between Maker and Payee shall,  at
the time  performance or fulfillment of such provision  shall be due, exceed the
limit  for  Interest  prescribed  by law or  otherwise  transcend  the  limit of
validity  prescribed by applicable law, then,  ipso facto,  the obligation to be
performed  or  fulfilled  shall  be  reduced  to such  limit,  and if,  from any
circumstance  whatsoever,  Payee 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  owing under this A Note in the inverse order of its maturity
(whether or not then due) or, at the option of Payee, be paid over to Maker, and
not to the payment of Interest.  All Interest (including any amounts or payments
judicially  or otherwise  under the law deemed to be Interest)  contracted  for,
charged,  taken,  reserved,  paid or  agreed to be paid to Payee  shall,  to the
extent permitted by applicable law, be amortized, prorated, allocated and spread
throughout  the full term of this A Note,  including any extensions and renewals
hereof until payment in full of the principal balance of this A Note so that the
Interest  thereon  for such full term  will not  exceed at any time the  maximum
amount  permitted by applicable  law. To the extent  United  States  federal law
permits a greater  amount of  interest  than is  permitted  under the law of the
State in which the  Security  Property  is  located,  Payee  will rely on United
States federal law for the purpose of determining  the maximum amount  permitted
by applicable law.  Additionally,  to the extent permitted by applicable law now
or  hereafter  in

                                       10
<PAGE>

effect, Payee may, at its option and from time to time, implement any other
method of computing the maximum lawful rate under the law of the State in which
the Security Property is located or under other applicable law by giving notice,
if required, to Maker as provided by applicable law now or hereafter in effect.
This Section 4.3 will control all agreements between Maker and Payee.

      4.4. Use of Funds. Maker hereby warrants, represents and covenants that no
funds  disbursed  hereunder  shall be used for  personal,  family  or  household
purposes.

      4.5.  Unconditional  Payment.  Maker  is and  shall  be  obligated  to pay
principal, interest and any and all other amounts which become payable hereunder
or under the other Loan Documents absolutely and unconditionally and without any
abatement,  postponement,  diminution or deduction and without any reduction for
counterclaim  or setoff.  In the event that at any time any payment  received by
Payee  hereunder  shall be deemed by a court of competent  jurisdiction  to have
been a  voidable  preference  or  fraudulent  conveyance  under any  bankruptcy,
insolvency or other debtor relief law, then the  obligation to make such payment
shall survive any  cancellation or satisfaction of this A Note or return thereof
to Maker and shall not be discharged or satisfied with any prior payment thereof
or cancellation of this A Note, but shall remain a valid and binding  obligation
enforceable in accordance with the terms and provisions hereof, and such payment
shall be immediately due and payable upon demand.

      4.6.  Governing  Law.  THIS A NOTE  SHALL BE  INTERPRETED,  CONSTRUED  AND
ENFORCED  ACCORDING TO THE LAWS OF THE STATE IN WHICH THE  SECURITY  PROPERTY IS
LOCATED.

      4.7.  Waiver of Jury Trial.  MAKER,  TO THE FULL EXTENT  PERMITTED BY LAW,
HEREBY  KNOWINGLY,  INTENTIONALLY  AND VOLUNTARILY,  WITH AND UPON THE ADVICE OF
COMPETENT COUNSEL, WAIVES, RELINQUISHES AND FOREVER FORGOES THE RIGHT TO A TRIAL
BY JURY IN ANY ACTION OR  PROCEEDING  BASED UPON,  ARISING OUT OF, OR IN ANY WAY
RELATING TO THE DEBT EVIDENCED BY THIS A NOTE OR ANY CONDUCT, ACT OR OMISSION OF
PAYEE  OR  MAKER,  OR ANY OF THEIR  RESPECTIVE  DIRECTORS,  OFFICERS,  PARTNERS,
MEMBERS,  EMPLOYEES,  AGENTS OR ATTORNEYS,  OR ANY OTHER PERSONS AFFILIATED WITH
PAYEE OR MAKER, IN EACH OF THE FOREGOING  CASES,  WHETHER  SOUNDING IN CONTRACT,
TORT OR OTHERWISE.

      4.8.  Secondary  Market.  Payee may sell,  transfer  and  deliver the Loan
Documents  to  one or  more  investors  in the  secondary  mortgage  market.  In
connection  with such  sale,  Payee may  retain  or  assign  responsibility  for
servicing the loan  evidenced by this A Note or may delegate some or all of such
responsibility and/or obligations to a servicer,  including, but not limited to,
any subservicer or master servicer,  on behalf of the investors.  All references
to  Payee  herein  shall  refer to and  include,  without  limitation,  any such
servicer, to the extent applicable.

      4.9.  Dissemination  of  Information.  If Payee  determines at any time to
sell, transfer or assign this A Note, the Security Instrument and the other Loan
Documents,  and any or all servicing  rights with respect  thereto,  or to grant
participations  therein (the  "PARTICIPATIONS")  or issue mortgage  pass-through
certificates or other securities  evidencing a beneficial interest in a rated or
unrated  public  offering or private  placement  (the  "SECURITIES"),  Payee may
forward  to  each  purchaser,   transferee,   assignee,  servicer,  participant,
investor,   or  their  respective   successors  in  such  Participations  and/or
Securities  (collectively,  the  "INVESTOR")  or any Rating  Agency  rating such
Securities,  each  prospective  Investor and each of the foregoing's  respective
counsel,  all  documents  and  information  which Payee now has or may hereafter
acquire  relating  to the  debt  evidenced  by  this A Note  and to  Maker,  any
guarantor,  any  indemnitor  and the  Security  Property,  which shall have been
furnished  by  Maker,  any  guarantor  or any  indemnitor  as  Payee  determines
necessary or desirable.

      4.10.  Splitting the Loan.  Payee shall have the right at no cost to Maker
from time to time to sever this A Note and the other Loan  Documents into one or
more separate notes, mortgages, deeds of trust and other security documents (the
"SEVERED LOAN  DOCUMENTS") in such  denominations  and priorities as Payee shall
determine in its sole discretion,  provided, however, that the terms, provisions
and clauses of the Severed Loan Documents shall be no more adverse to Maker than
those  contained  in this A Note,  the  Security  Instrument  and the other Loan
Documents.  Maker shall execute and deliver to Payee from time to time, promptly
after the request of Payee,  a severance  agreement and such other  documents as
Payee shall reasonably request in order to effect the severance described in the
preceding sentence, all in form and substance reasonably  satisfactory to Payee.
Maker hereby  absolutely and  irrevocably  appoints Payee as its true and lawful
attorney,  coupled with an  interest,  in its name and stead to make and execute
all documents  necessary or desirable to effect the aforesaid  severance,  Maker
ratifying  all that its said  attorney  shall do by  virtue  thereof;  provided,
however,  that Payee  shall not make or execute  any such  documents  under such
power  until  three (3) days  after  notice  has been given to Maker by Payee of
Payee's intent to exercise its rights under such power.

                      ARTICLE V. - MISCELLANEOUS PROVISIONS

      5.1. Miscellaneous.  The terms and provisions hereof shall be binding upon
and  inure to the  benefit  of Maker  and  Payee  and  their  respective  heirs,
executors, legal representatives,  successors,  successors-in-title and assigns,
whether by  voluntary  action of the  parties or by  operation  of law.  As used
herein,  the  terms  "Maker"  and  "Payee"  shall be  deemed  to  include  their
respective    heirs,    executors,     legal    representatives,     successors,
successors-in-title  and assigns,  whether by voluntary action of the parties or
by operation of law. If Maker  consists of more than one person or entity,  each
shall be jointly and severally  liable to perform the obligations of Maker under
this A Note. All personal  pronouns used herein,  whether used in the masculine,
feminine or neuter gender,  shall include all other genders;  the singular shall
include  the plural and vice  versa.  Titles of articles  and  sections  are for
convenience only and in no way define,  limit,  amplify or describe the scope or
intent of any  provisions  hereof.  Time is of the essence  with  respect to all
provisions of this A Note. This A Note and the other Loan Documents  contain the
entire  agreements  between the parties  hereto  relating to the subject  matter
hereof and thereof and all prior  agreements  relative  hereto and thereto which
are not contained herein or therein are terminated.

      5.2.  Taxpayer  Identification.   Maker's  Tax  Identification  Number  is
13-4196336.
