the exercise of any other power or right. The rights and remedies of the Lender

otherwise has.

Advances are fully disbursed by the Escrow Company or are withheld in full or in
part.

     (c) ADVANCES BY LENDER TO ITSELF OR OTHERS. The Lender may, at the Lender's
option, advance to itself or to others all sums due or to become due to the
Lender or to others under any of the Loan Documents, whether or not an Advance
is requested by the Borrower.

     (d) INSPECTIONS. The Lender, the Escrow Company, the Inspecting Architect,
the Lender's consultants and their representatives shall have access to the
Project at all reasonable times to conduct such inspections thereof as they deem
necessary or desirable for the protection of the Lender's interests. All costs
of the Inspecting Architect and any other consultants deemed necessary or
desirable by the Lender to make periodic inspections of the Project and to
review all Draw Requests and change orders shall be paid by the Borrower.
Neither the Borrower nor any third party shall have the right to use or rely
upon the reports of the Inspecting Architect or any other reports generated by
the Lender or its consultants for any purpose whatsoever. By advancing funds
after any inspection of the Project, the Lender shall not be deemed to waive any
Default or Event of Default, waive any right to require construction defects to
be corrected, or acknowledge that all construction conforms with the Plans.

     (e) LENDER NOT RESPONSIBLE FOR PROJECT. The Lender assumes no liability or
responsibility for the sufficiency of the Loan proceeds to complete the Project,
to service any interest or other payment due under the terms of the Loan under
Section 2(c) above, for protection of the Project, for the satisfactory
Completion of the Project, for the Plans, for the compliance of the Plans and
the Project with Governmental Requirements, for inspection during construction,
for the adequacy of Reserves, for the adequacy or accuracy of the Sworn Project
Cost Statement, for any representations made by the Borrower, or for any acts on
the part of the Borrower or its Contractors to be performed in

the construction of the Project. The Borrower assumes sole responsibility for
all of the foregoing.

     (f) LOAN IN BALANCE. Borrower acknowledges that Borrower is responsible for
all cost overruns on the Project. The Lender shall not be obligated to make any
Advance unless and until the Borrower has provided the Lender with evidence that
the Borrower has paid sufficient costs of the Project so that all remaining
unpaid costs of the Project, including the Reserves, do not exceed the amount of
the Loan proceeds not yet Advanced by the Lender. If the Lender or the Borrower
determines that the unAdvanced balance of Loan proceeds is insufficient to cover
any cost allocation set forth on the Sworn Project Cost Statement, including the
Reserves and interest during construction, or to complete the Project, it shall
notify the other party of such determination, and the Borrower shall, within ten
(10) Business Days after such notice, deposit with the Lender funds equal to the
amount of the deficiency. The Borrower hereby assigns and pledges to the Lender
all funds so deposited as additional security for the Obligations. The Borrower
may not reallocate items of cost or change the Sworn Project Cost Statement
without the consent of the Lender.

     Section 3. CONDITIONS PRECEDENT TO ADVANCES. The Lender shall not be
required to make any Advances until the conditions and requirements set forth
below have been satisfied, at the Borrower's sole cost and expense. The Lender
may, in its discretion, make Advances prior to satisfaction of any or all of the
conditions and requirements set forth below, all of which are for the sole
benefit of the Lender, without waiving its right to require such satisfaction
before any additional Advances are made.

     (a) CONDITIONS PRECEDENT TO INITIAL ADVANCE. The Lender shall not be
obligated to make the initial Advance until the conditions precedent set forth
in Article III of the Loan Agreement have been satisfied and the Lender has
received all of the following in form and substance acceptable to the Lender:

     (i)    The Plans.

     (ii) Soil reports on the Land, showing that the soil will adequately
     support the Improvements when constructed in accordance with the Plans.

     (vii) Letters from the appropriate municipalities or utility companies

     services necessary to construct and operate the Project.

     (viii) The Assignment of Construction Contract and the Assignment of Plans
     and the Disbursing Agreement, each duly executed by the parties thereto.

     (x) The parties acknowledge that work on the Improvements commenced prior
     to closing, and that all preconditions to any subsequent Advances hereunder
     apply to the initial Advance hereunder.

     (b)    CONDITIONS PRECEDENT TO ALL ADVANCES. The obligation of the Lender
to make each Advance (including the initial Advance) is subject to the following
conditions precedent:

     (i) No Default or Event of Default shall have occurred and be continuing or
     will exist upon the making of such Advance.

     (ii) All representations and warranties of the Borrower made in the Loan
     Agreement shall remain true and correct as of the date of the Advance as
     though made on and as of such date, except to the extent that such
     representations and warranties relate solely to an earlier date and no
     Default or Event of Default shall exist.

     (iii) All requirements and conditions for an Advance under Section 2 of
     this Addendum shall have been complied with and satisfied.

<Page>

     (iv) There shall not have occurred any change, which in the sole judgment
     of the Lender is materially adverse, in the condition (financial or
     otherwise) or operations of the Borrower or in the Project or the prospects
     for the timely and satisfactory completion of the construction of the
     Improvements and operation of the Project.

     Section 4. WARRANTIES, REPRESENTATIONS, COVENANTS AND AGREEMENTS. In
addition to the warranties, representations, covenants and agreements of the
Borrower contained in the Loan Agreement, the Borrower hereby warrants,
represents, covenants and agrees to and with the Lender as follows:

     (a) BOUNDARY LINES, GOVERNMENTAL REQUIREMENTS AND RESTRICTIONS. The
exterior lines of the Improvements are, and at all times will be, within the
boundary lines of the Land and any required set back lines, and the Borrower has
examined and is familiar with all applicable covenants, conditions, restrictions
and reservations, and with all applicable Governmental Requirements affecting
the Project, and the Project will conform to and comply with all of the
foregoing.

     (b)    LOAN IN BALANCE. The amount of the Loan proceeds not yet advanced by
the Lender equals or exceeds the total of all remaining unpaid costs of the
Project, including the Reserves.

     (c) COMMENCING AND COMPLETING CONSTRUCTION. Regardless of whether or not
there are sufficient Loan proceeds or sufficient funds disbursed under the
Disbursing Agreement, the Borrower shall expeditiously complete and fully pay
for the development and construction of the Project in a good and workmanlike
manner and in accordance with the contracts, subcontracts and Plans submitted to
and approved by the Lender, and in compliance with all applicable Governmental
Requirements, and any applicable covenants, conditions, restrictions and
reservations, so that Completion occurs on or before the Completion Deadline.
The Borrower shall correct or cause to be corrected (a) any defect in the
Improvements, (b) any departure in the construction of the Improvements from the
Plans or Governmental Requirements, and (c) any encroachment by any part of the
Improvements or any other structure located on the Loan on any building line,
easement, property line or restricted area. The Borrower shall cause the bearing
capacity of the soil on the Loan to be made sufficient to support the
Improvements, and sufficient local utilities to be made available to the Project
and installed at costs (if any) set out in the Sworn Project Cost Statement, on
or before the Completion Deadline.

     (d)    CHANGING COSTS, SCOPE OR TIMING OF WORK. The Borrower shall deliver
to the Lender revised, sworn statements of estimated costs of the Project,
showing changes

<Page>

in or variations from the original Sworn Project Cost Statement, as soon as such
changes are known to the Borrower. The Borrower shall furnish the Lender with
copies of all changes or modifications in the Plans, contracts or subcontracts
for the construction of the Improvements, prior to incorporation of any such
change or modification into the Improvements, whether or not the Lender's
consent to such change or modification is required. The Borrower shall not make
or consent to any change or modification in such Plans, contracts or
subcontracts, and no work shall be performed with respect to any such change or
modification, without the prior written consent of Lender, if such change or
modification would in any material way alter the design or structure of the
Improvements, or increase or decrease the cost of the construction of the
Improvements by $250,000.00 or more for any single change or modification, or if
the aggregate amount of all changes and modifications exceeds $1,000,000.00.

     (e) PAYING COSTS OF PROJECT AND LOAN. The Borrower shall pay and discharge,
when due, all taxes, assessments and other governmental charges upon the
Project, as well as all claims for labor and materials which, if unpaid, might
become a lien or charge upon the Project; provided, however, that the Borrower
shall have the right to contest the amount, validity and/or applicability of any
of the foregoing in strict accordance with the terms of the Mortgage. The
Borrower shall also pay all costs and expenses of the Lender, the Lender's
consultants and the Borrower in connection with the Project, the preparation and
review of the Loan Documents and the making, closing, administration, repayment
and/or transfer of the Loan, including but not limited to the fees of the
Lender's attorneys, fees of the Inspecting Architect, title insurance costs,
disbursement expenses, and all other costs and expenses payable to third parties
incurred by the Lender or the Borrower in connection with the Loan. Such costs
and expenses shall be paid by the Borrower whether or not the Loan is fully
advanced or disbursed.

     (f) USING LOAN PROCEEDS. The Borrower shall use the Loan proceeds solely to
pay, or to reimburse the Borrower for paying, costs and expenses shown on the
Sworn Project Cost Statement approved by the Lender and incurred by the Borrower
in connection with the acquisition, development and construction of the Project.
The Borrower shall take all steps necessary to assure such use of Loan proceeds
by its Contractors.

     (g) KEEPING RECORDS. The Borrower shall maintain accurate and complete
books, accounts and records pertaining to the Project in a manner reasonably
acceptable to the Lender and to the Escrow Company. The Borrower will permit
representatives of the Lender, the Inspecting Architect and the Escrow Company
to have free access to and to inspect and copy all books, records and contracts
of the Borrower.

<Page>

     (h) PROVIDING EVIDENCE OF COMPLETION. Upon Completion, and prior to the
final Advance of Loan proceeds to pay for hard costs of construction of the
Project, and as a condition of the same, the Borrower shall furnish the Lender
with all items required to evidence Completion, including an unconditional
occupancy certificate if required by applicable law to occupy the Project; a
zoning endorsement (Form 3.1 or equivalent) to the Title Policy; a final,
certified Project "as-built" survey (3 copies) if requested by Lender; the
evidence of insurance required by Section 1.4 of the Mortgage; and photographs
of the completed Improvements.

     Section 5. EVENTS OF DEFAULT. In addition to the Events of Default set
forth in Article VI of the Loan Agreement, the following events shall constitute
an Event of Default under the Loan Agreement:

     (a) ABANDONMENT OF OR DELAY IN CONSTRUCTION. Work on the Project shall be
substantially abandoned, or shall, by reason of the Borrower's fault, be
unreasonably delayed or discontinued for a period of thirty (30) days, or shall
be delayed for any reason whatsoever to the extent that Completion of the
Project cannot, in the reasonable judgment of the Lender, be accomplished prior
to the Completion Deadline.

     (b) LOAN IMBALANCE NOT REMEDIED. The Lender determines that the remaining
undisbursed Loan proceeds are insufficient to fully pay all of the then unpaid
costs of the Project and estimated expenses of completion, and the Borrower (i)
fails to deposit with the Lender, within ten (10) Business Days after demand,
sufficient funds to permit the Lender to pay said excess costs as the same
become payable or (ii) does not pay said excess costs directly and deliver to
the Lender unconditional mechanics' lien waivers therefor (or paid receipts for
nonlienable items), at the Lender's option.

     Section 6. REMEDIES. If an Event of Default shall occur under the Loan
Agreement, then in addition to the rights and remedies set forth in the Loan
Agreement and the other Loan Documents, the Lender shall be entitled, at the
option of the Lender, to exercise any or all of the following rights and
remedies:

     (a)    MAKE OR REFRAIN FROM MAKING FURTHER ADVANCES. The Lender may make
one(1) or more further Advances, without liability to make any subsequent
Advances.

     (b)    SUSPEND ADVANCES. The Lender may suspend or terminate its obligation
to make Advances, and if it does so, shall promptly notify Borrower.

     (c)    COMPLETION OF IMPROVEMENTS BY THE LENDER. In addition, in case of
the occurrence of any Event of Default caused by, or which results in, the
Borrower's failure,

<Page>

for any reason, to continue with the construction of the Project as required by
the Loan Agreement and this Addendum, the Lender may (but shall not be obligated
to) take over and complete the construction of the Project in accordance with
the Plans, with such changes therein as the Lender may, in its discretion, deem
appropriate, all at the risk, cost and expense of the Borrower. The Lender may
assume or reject any contracts entered into by the Borrower in connection with
the Project, may enter into additional or different contracts, and may pay,
compromise and settle all claims in connection with the Project. All costs and
expenses, including attorneys' fees, incurred by the Lender in completing or
attempting to complete the Project (whether aggregating more, or less, than the
face amount of the Note), shall be deemed Advances made by the Lender to the
Borrower hereunder, and the Borrower shall be liable to the Lender, on demand,
for the repayment of such sums, together with interest on such sums from the
date of their expenditure at the Default Rate. The Lender may, in its
discretion, at any time abandon work on the Project, after having commenced such
work, and may recommence such work at any time. Nothing in this Section 6(c)
shall impose any obligation on the Lender either to complete or not to complete
the Project. For the purpose of carrying out the provisions of this Section
6(c), the Borrower irrevocably appoints the Lender its attorney-in-fact, with
full power of substitution, to execute and deliver all such documents, to pay
and receive such funds, and to take such action as may be necessary, in the
judgment of the Lender, to complete the Project. This power of attorney is
coupled with an interest and is irrevocable.

     IN WITNESS WHEREOF, the parties hereto have caused this Construction Loan
Addendum to be executed the same date as execution of the Loan Agreement.
