          increased costs shall show the manner of calculation and shall be
          conclusive (absent manifest error) as to the amount thereof; and

     (e)  Company's obligations to make payments to Bank under this Section 2
          shall be deemed satisfied to the extent of payments made by the
          Trustee to Bank from funds on deposit with and held by the Trustee
          pursuant to the Indenture.

     Section 2.3.  Company's Obligations Unconditional. The payment obligations

     (c)  The existence of any claim, setoff, defense or right which Company may
          have at any time against any beneficiary or any transferee of the

          person or entity, whether in connection with this Reimbursement
          Agreement, the transactions contemplated by the Credit Documents or
          the Bond Documents, or any unrelated transaction;

     (d)  Any statement or any other document presented under the Letter of

          to any of the foregoing.

     Section 2.4.  Payments. The payments and amounts due Bank under Section 2.2

extend the Expiration Date. Bank shall notify Company and Trustee of its
decision of whether the Expiration Date shall be extended no later than ninety

shall do so in the form of an amendment to the Letter of Credit, which it shall
promptly deliver to Trustee.

for disbursements to be made from the Trust Estate (as defined in the Bond
Documents). All requests for disbursement with respect to construction costs
shall be accompanied by executed AIA Forms G-702 and G-703. Bank shall not be
required to approve disbursement of funds for any line item in excess of the
amount shown on Bank's Use of Proceeds form; however,

                                       18

<PAGE>

Company may request an increase in a line item by reducing a budgeted line item.
Any such reallocation shall not cause a deficiency with respect to the
"Company's Equity" category, and must be substantiated by a cost saving in the
line item being reduced. All authorizations of draw requests shall be made
within ten (10) days after receipt of all information required by Bank to
approve the draw requests.

     Section 5.5.  Timing. Company will submit draw requests not more often than
once a month. Each disbursement shall not be more than ninety (90%) of the value
of construction work which has been completed and which is covered by such
disbursement until the Project is fully completed, and the balance will be paid
upon completion based on requirements set forth below. Retainage will be held on
a subcontract by subcontract basis, and released in connection with a particular
subcontract upon the expiration of the time for filing of any mechanic's lien
with respect to such subcontract provided all work thereunder has been completed
to the satisfaction of Bank and its inspector and a mechanic's lien waiver has
been received from the subcontractor for all their work done on the property.
There are no retainage requirements for "soft costs" on the Project. "Soft
costs" are defined as expenses which have no mechanic's lien rights on the
subject security (this does not include the contingency line item under the
Construction Contract). Upon completion of all work and prior to disbursement of
the retainage, Company shall submit evidence of substantial completion of the
Project, consisting of a certificate of the Project Architect and a certificate
of occupancy for the Facility. Notwithstanding the foregoing, Bank, in its sole
discretion, may elect to release the retainage prior to completion of the
Project.

     Section 5.6.  Supporting Documentation. Company shall furnish Bank with an
affidavit of Company identifying all subcontractors and materialmen who have
performed work or furnished materials in connection with the Project, together
with lien waivers from the Contractor and from all subcontractors and
materialmen who have provided notices of furnishing or who have performed work
or furnished materials in connection with the Project, current through the end
of the period covered by Company's most recent request, and such other evidence
or affidavits required by Bank at the time of each request to ensure that all
bills then due and payable for labor and materials used in constructing the
Facility and all bills due and payable to the Contractor, subcontractors,
materialmen and their respective subcontractors, laborers, and material
suppliers have been paid in full, except those bills to be paid with the
proceeds of such disbursement, and except for retainages. Bank shall be provided
with an update to the Title Policy as of the date of the draw request, showing
no additional liens or encumbrances upon the Premises.

     Section 5.7.  Material Damage. Notwithstanding any provision of this
Reimbursement Agreement to the contrary, if the Premises shall have suffered any
material damage or destruction prior to any disbursement from the Project Fund,
such damaged or destroyed portion shall be restored or replaced in a manner
acceptable to Bank without cost to Bank prior to the approval by Bank of any
further disbursement from the Project Fund.

     Section 5.8.  Other Disbursement Approval Conditions. Bank shall not be
obligated to approve any disbursement from the Project Fund if, at the time of a
proposed disbursement, (i) an Event of Default or an event which, with the
passage of time or service of notice, or both, would be an Event of Default
under any of the Credit Documents has occurred, or (ii) any representation or
warranty made by Company in any of the Credit Documents proves to be

                                       19

<PAGE>

untrue in any material respect, or (iii) Bank determines, at any time, that the
Project will not be approved by the appropriate governmental regulatory
authorities.

     Section 5.9.  Permits. Company shall have delivered to Bank building,
zoning, and other required permits covering construction of the Facility
together with evidence satisfactory to Bank that all approvals required with
respect to the Premises from third parties or any governmental or
quasi-governmental authorities have been obtained or, in the case of approvals
relating to the operation of the Facility which cannot be obtained until
completion of construction, evidence satisfactory to Bank that such approvals
are obtainable.

     Section 5.10. Utilities. [Intentionally Omitted]

     Section 5.11. Conditions for Final Disbursement. Company will, on or prior
to the date of the final disbursement from the Project Fund, deliver or cause to
be delivered to Bank the following:

     (a)  If required by Bank, an additional endorsement to the Title Policy
          insuring the priority of the Mortgage in the full amount of the Letter
          of Credit against mechanic's and materialmen's liens (including
          inchoate liens) arising by reason of unpaid labor and materials
          supplied in connection with the construction and development of the
          Facility;

     (b)  An affidavit of Company stating that each person providing any
          material or performing any work in connection with the Premises has
          been (or will be, with the proceeds of and immediately following
          receipt by Company of such final disbursement) paid in full or bonded
          or insured to the reasonable satisfaction of Bank;

     (c)  Notification from the Construction Inspector to the effect that the
          improvements to the Premises have been completed in a good and
          workmanlike manner in accordance with the applicable Plans and
          Specifications;

     (d)  An as-built survey certified to the Bank and the Title Company showing
          the location of the completed improvements to the Premises; and

     (e)  A certificate of occupancy with respect to the completed improvements
          to the Premises.

     Section 5.12. Sufficiency of Project Fund to Complete Construction.
Notwithstanding anything contained in this Reimbursement Agreement to the
contrary, it is expressly understood and agreed that the Project Fund and equity
to be received from Company during construction (collectively, the "Construction
Proceeds") shall at all times be "in balance." The Construction Proceeds shall
be deemed to be "in balance" only at such time and from time to time, as Bank
may determine in Bank's sole discretion based on the certification of Bank's
Inspector that the then undisbursed portion of the Construction Proceeds equals
or exceeds the amount necessary for the timely and full payment of (i) all work
done and not theretofore paid for or to be done in connection with the
completion of the construction of the Facility in accordance with the Plans and
Specifications, including the installation of all fixtures and

                                       20

<PAGE>

equipment required for operation of the Facility and the Premises, and (ii) all
other costs and expenses incurred and not theretofore paid for, or to be
incurred in connection with the Project and the Premises (to the extent revenues
will not, in Bank's sole judgment, be sufficient for the timely and full payment
of such costs and expenses). Company agrees that if the Construction Proceeds
are deemed not to be "in balance," Company shall, within thirty (30) days after
written request by Bank, deposit the deficiency with Bank (the "Deficiency
Deposit"), which Deficiency Deposit shall first be exhausted before any further
disbursement from the Construction Proceeds is made. Bank shall not be obligated
to make any disbursement if the Construction Proceeds are not in balance.

     Section 5.13. Contractors May Be Paid Directly. Bank reserves the right to
direct that the Trustee pay individual contractors directly upon the occurrence
of any Event of Default under the Credit Documents.

                                   SECTION SIX

          effect of increasing the cost of the Project either by itself or when
          aggregated with any prior change orders to which the Bank's consent

          an amount not in excess of the Change Order Amount; and

disbursements after the filing or service upon Bank of any notice of mechanic's,
materialman's or laborer's lien until such lien is bonded or released.

          of the Bonds prior to maturity (the "Credit") pursuant to an optional

          any time thereafter to reduce permanently, without penalty or premium,
          the Letter of Credit Commitment in the manner set forth below. The

     (c)  If the Letter of Credit Commitment shall be reduced pursuant to
          paragraph (b) hereof, and Bank shall have received from the Trustee
          the outstanding Letter of Credit then, in substitution for the then
          outstanding Letter of Credit, a substitute irrevocable letter of
          credit, shall be issued dated such date, for an amount equal to the
          amount to which the Letter of Credit Commitment shall have been so
          reduced (also less the amount of any drawings upon the Letter of
          Credit which have not been reinstated under paragraph (d) hereof) but
          otherwise having terms identical to the then outstanding Letter of
          Credit;

     (d)  The obligation of Bank to honor Interest Drawings, under the Letter of
          Credit, up to the aggregate amount of the Interest Commitment (as same
          may have been reduced pursuant to subsection (b) of this Section 8.1

          reinstated pro rata to the Interest Coverage Requirement on the date
          of payment of each Interest Drawing; and

     (e)  Bank shall reinstate pro rata amounts drawn under the Letter of Credit
          pursuant to a Remarketing Drawing as set forth in the Letter of
          Credit.

certificate signed by an officer of the Trustee and an authorized representative
of Company stating that no Bonds remain outstanding; (iii) receipt by Bank of
the Letter of Credit and a certificate signed by an officer of the Trustee and
an authorized representative of Company stating that "A Substitute Letter of
Credit or a Substitute Credit Facility in substitution for the Letter of Credit
has been accepted by the Trustee and is in effect"; or (iv) the stated
Expiration Date. Notwithstanding the foregoing, the Expiration Date may be
extended at Bank's option pursuant to Section 2.5 hereof.

     Section 9.1.  Liability of Bank. Between Company and Bank, Company assumes
all risks of the acts or omissions of the Trustee and any transferee of the
Letter of Credit with respect to its use of the Letter of Credit or its
proceeds. Neither Bank nor any of its officers or directors shall be liable or
responsible for: (a) the use which may be made of the Letter of Credit or its
proceeds or for any acts or omissions of the Trustee and any transferee in
connection therewith; (b) the validity, sufficiency or genuineness of documents,
inaccuracy of any of the statements or representations contained therein or of
any endorsement(s) thereon, even if such documents should in fact prove to be in
any or all respects invalid, insufficient, fraudulent or forged; (c) good faith
payment by Bank against presentation of documents which do not strictly comply
with the terms of the Letter of Credit, including any failure of any documents
to bear any reference or adequate reference to the Letter of Credit; or (d) any
other circumstances whatsoever in making or failing to make payment under the
Letter of Credit. In furtherance and not in limitation of the foregoing, Bank
may accept documents that appear on their face to be in order, and may assume
the genuineness and rightfulness of any signature thereon, without
responsibility for further investigation, regardless of any notice or
information to the contrary unless actually received by Bank; provided, that if
Bank shall receive written notification from both the Trustee and Company that
documents conforming to the terms of the Letter of Credit to be presented to
Bank are not to be honored, Bank agrees that it will not honor such documents
and Company shall indemnify and hold Bank harmless from such failure to honor.

     Section 9.2.  Right to Set-Off. Upon the occurrence of any Event of Default
hereunder Bank is hereby irrevocably authorized at any time and from time to
time without notice to Company, any such notice being expressly waived by
Company, to set-off and appropriate and apply any and all deposits (general or
special, time or demand, provisional or final), in any currency, any other
credits, indebtedness or claims, in any currency, in each case whether direct or
indirect or contingent or matured or unmatured, at any time held or owing by
Bank to or for the credit or the account of Company, or any part thereof in such
amounts as Bank may elect, against and on account of the obligations and
liabilities of Company to Bank hereunder and claims of every nature and
description of Bank against Company, whether arising hereunder or otherwise, as
Bank may elect, whether or not Bank has made any demand for payment and although
such obligations, liabilities and claims may be contingent or unmatured. Bank
agrees to notify in writing Company promptly of any such set-off and the
application made by Bank, provided that the failure to give such notice shall
not affect the validity of such set-off and

Reimbursement Agreement, Company agrees that in the event that Trustee shall,

of the indebtedness evidenced hereby, draw upon the Letter of Credit to pay all
Bonds, Bank shall be and become the assignee of all rights and interests of the
Agency and the Trustee, all as provided more fully in the Indenture. Company
does hereby consent to such Assignment, and does agree to execute any and all
such documents, instruments and certificates in connection therewith as Bank
shall deem appropriate.

     Section 9.4.  Optional Redemption. If Company elects to exercise its option
to direct redemption of the Bonds by a prepayment, Company shall give Bank three
(3) days' prior written notice of such intent. Prior to notifying the Trustee of
its election to redeem the Bonds, Company shall deliver moneys (in good and
collected funds) in an amount equal to the amount necessary to effect the
redemption to Bank and Bank shall then inform the Trustee that those moneys are
on deposit and that the Trustee may draw on the Letter of Credit to effect that
redemption of the Bonds.

     Section 9.5.  Pledge of Bonds. Bonds which are not remarketed shall be held
by the Trustee, as agent for Bank, as security for the obligations of Company
under the Bond Pledge. Company hereby grants a lien on such Bonds while they are
so held by the Trustee.
