materials, and services incorporated into the Improvements in accordance with
the Development Agreement and the Construction Contract, plus (b) the purchase
price of all uninstalled materials to be utilized in the construction of the
Improvements stored on the Property, or elsewhere in accordance with the
Development Agreement and the Construction Contract, less (c) all prior Advances
for payment of costs of labor, materials, and services for the construction of
the Improvements or in the consummation of this Loan.

      2.6   Use of Advances. Borrower shall disburse all Advances for payment of
costs and expenses incurred for the development, financing, and construction of
the Improvements as specified in the Approved Budget, and most recently
requested on an Application for Advance, and for no other purpose.

      2.7   The Borrower's Deposit. If Lender and Inspecting
Architects/Engineers at any time make a reasonable good-faith determination that
the amount of the unadvanced portion of the Loan will not be sufficient to pay
fully for all costs required to complete the construction of the Improvements in
accordance with the approved Plans and Approved Budget, whether such deficiency
is attributable to changes in the work of construction or in the Plans or to any
other cause, Lender may make written demand on Borrower to deliver to Lender the
amount of the shortage determined by Lender (the "Borrower's Deposit"), which
Borrower's Deposit shall be placed in an interest bearing account by Lender.
Borrower shall deposit the amount of the Borrower's Deposit within thirty (30)
days after the date of Lender's written demand. No further Advances need be made
by Lender until the Borrower's Deposit is made by Borrower. Borrower shall
promptly notify Lender in writing if and when, to Borrower's Knowledge, the cost
of the

                                      -10-
<PAGE>

construction of the Improvements exceeds, or appears likely to exceed, the
amount of the unadvanced portion of the Loan and the unadvanced portion of the
Borrower's Deposit.

      2.8   Direct Disbursement and Application by Lender. Lender shall have the
right, but not the obligation, following at least five (5) days' prior written
notice to Borrower, to disburse and apply the proceeds of any Advance to the
satisfaction of any of Borrower's obligations hereunder directly to Contractor,
the Title Company, and any other person or firm to whom payment is due under
this Agreement or any other Loan Documents, except with respect to any payment
contested by Borrower pursuant to Section 4.22 hereof. Any Advance by Lender for
such purpose, except Borrower's Deposit, shall be part of the Loan and shall be
secured by the Loan Documents. Subject to Borrower's right to contest a claim
pursuant to Section 4.22 hereof, Borrower hereby authorizes Lender, following at
least five (5) business days' prior written notice to Borrower, to hold, use,
disburse, and apply the Loan and the Borrower's Deposit for payment of costs of
construction of the Improvements, expenses incident to the Loan and the
Property, and the payment or performance of any obligation of Borrower
hereunder, including, without limitation, interest on the Loan, any Loan fees
owing to Lender, legal fees of Lender's attorneys which are payable by Borrower,
and such other sums as may be owing from time to time by Borrower to Lender with
respect to the Loan. Such payments may be made, at the option of Lender
following at least five (5) business days' prior written notice to Borrower, by
(a) debiting or charging Borrower's Loan account in the amount of such payments
without first disbursing such amounts to Borrower, or (b) advancing all or any
part of the amount of such payments to Borrower and then invoicing Borrower
therefor. No further direction or authorization from Borrower shall be necessary
to warrant such direct Advances and all such Advances shall satisfy pro tanto
the obligations of Lender hereunder and shall be secured by the Loan Documents
as rally as if made directly to Borrower. Notwithstanding the other provisions
of this paragraph, nothing in this Agreement is intended to be for the benefit
of, nor may be enforced by, nor should be relied upon by, any person, firm or
corporation other than Borrower.

      2.9   Advances Do Not Constitute A Waiver. No Advance shall constitute a
waiver of any of the conditions of Lender's obligations to make further Advances
nor, in the event Borrower is unable to satisfy any such condition, shall any
such waiver have the effect of precluding Lender from thereafter declaring an
Event of Default hereunder with respect to any such inability which shall
constitute an Event of Default.

      2.10  Conditions to the First Advance. As a condition precedent to the
first Advance hereunder (the "First Advance"), Borrower must satisfy the
conditions required hereby and set forth elsewhere in this Agreement and deliver
to Lender, the documents, certificates, and other items that are set forth
below:

      applicable Governmental Authority, with all costs and expenses of the
      installation and acceptance thereof having been paid in full, and that
      there are no restrictions on the use and enjoyment of such streets that
      adversely affect, limit, or impair Borrower's ability to develop and
      construct the Property or operate the Property for the purposes and in the
      manner represented to Lender;

      Agreement and all Loan Documents to be executed and delivered by or on
      behalf of Borrower will be valid and binding upon Borrower or the person

      terms. Such evidence shall include the legal opinion of legal counsel for

      ($5,118,823.00) has been invested in or loaned to Borrower, and that such
      amount will be spent by Borrower to defray the costs of the Project before
      any advances are made by Lender to Borrower, provided that Lender hereby
      acknowledges that certain affiliates of the Borrower have previously
      advanced to Borrower the sum of approximately One Million Nine Hundred
      Sixty-Three Thousand Three Hundred Seventy-Four and 71/100 Dollars
      ($1,963,374.71) to fund initial construction costs of the Improvements and

      been furnished to Borrower or by reason of the development, design or
      construction of the Improvements including, without limitation, any tests,
      investigations or studies ordered or conducted by Borrower (excluding,
      however, any liens filed as a direct result of MOB Owner's failure to

      or any contractor or subcontractor, which evidence shall include an
      endorsement to the Title Policy evidencing that no mechanics' and
      materialmen's liens or other encumbrances have been filed against the
      Property, except as permitted herein;

            (d)   Evidence that the Developer, Developer's authorized

                                      -16-
<PAGE>

      2.14  Reallocation of Approved Budget. Lender reserves the right, upon
Borrower's prior written consent (which consent may not be unreasonably
withheld, conditioned, or delayed), to make Advances which are allocated to any
of the designated items in the Approved Budget for such other purposes or in
such different proportions as Lender may, in its reasonable discretion, deem
necessary or advisable. With the prior written consent of Lender (which consent
may not be unreasonably withheld, conditioned, or delayed), Borrower shall be
entitled to make reallocations from items in the Approved Budget for which
substantial completion has been achieved as determined by Lender and no further
funds are required, to the extent of any amount remaining in such item.

      2.15  Conditions Precedent for the Benefit of Lender. All conditions
precedent to the obligation of Lender to make any Advance are imposed hereby
solely for the benefit of Lender, and no other party may require satisfaction of
any such condition precedent or be entitled to assume that Lender will refuse to
make any Advance in the absence of strict compliance with such conditions
precedent. All requirements of this Agreement may be waived by Lender, in whole
or in part, at any time.

      2.16  Subordination. Lender shall not be obligated to make, nor shall
Borrower be entitled to, any Advance until such time as Lender shall have
received, to the extent requested, by Lender, subordination agreements from
Architect, Contractor, and all other persons furnishing labor, materials, or
services for the design or construction of the Improvements, subordinating to
the lien of the Mortgage any Lien, claim, or charge they may have against
Borrower or the Property.

      2.17  Interest Reserve. Borrower acknowledges and agrees that the amount
of Nine Hundred Forty-One Thousand Eight Hundred Thirteen and No/100 Dollars
($941,813.00), as specified in the Approved Budget, represents reserves for
interest on the Loan (the "Interest Reserve"). So long as no Event of Default
exists and no event exists which with the giving of notice or the passage of
time or both would reasonably be expected to constitute an Event of Default,
interest due and payable under the Note may be paid from the Interest Reserve.
Borrower shall notify Lender in writing as to the amount to be disbursed from
the Interest Reserve, subject to verification by Lender. Borrower hereby
authorizes and directs Lender, and Lender shall have the right to, disburse and
charge the Interest Reserve for interest due under the Loan on the seventeenth
(17th) day of each month as interest payments become due and payable pursuant to
the terms of the Loan Documents. Such disbursements shall be made by a
bookkeeping entry on Lender's records and shall be reflected as additional
Advances under the Loan, in amounts equal to the accrued interest due and
payable on the seventeenth (17th) day of each month. Such bookkeeping entry
shall be deemed to be as if Borrower had delivered a check to Lender for the
amount in question. Unless otherwise directed by Lender in its sole discretion,
the Interest Reserve shall be available only for disbursements of the periodic
payments of accrued interest due to Lender on the Loan pursuant to the terms of
this Agreement and the other Loan Documents. Any funds disbursed in the manner
provided in this Section 2.17 shall have been deemed paid to and received by
Borrower.

      2.18  Maximum Funding Obligation. Lender shall have no obligation to make
Advances in excess of amounts Borrower has properly qualified in advance to
receive, and Lender shall have no obligation to make Advances in excess of
Fifteen Million Three Hundred

                                      -17-

Fifty-Six Thousand Five Hundred Seventy-Five and No/100 Dollars ($15,356,575.00)
(the "Maximum Funding Obligation").

                                  ARTICLE III.
                   REPRESENTATIONS AND WARRANTIES OF BORROWER

      3.1   The Financial Statements. The Financial Statements delivered by
Borrower to Lender on or prior to the date hereof were prepared in accordance
with generally accepted accounting principles and fairly present the financial
condition and results of operations of the Borrower for the respective periods
specified therein, except for the absence of footnotes and subject to normal
year-end adjustments which, in the aggregate, are not material. To Borrower's
Knowledge, no material adverse change has occurred in the financial condition of
Borrower since the period ending as of the last Financial Statement delivered by
Borrower to Lender.

      3.2   Suits, Actions, Etc. There are no actions, suits, or proceedings
pending or, to Borrower's Knowledge, threatened in any court or before or by any
Governmental Authority affecting Borrower or the Property, or involving the
validity or enforceability of any of the Loan Documents, at law or in equity.
The consummation of the transactions contemplated hereby, and the performance of
any of the terms and conditions hereof and of the other Loan Documents, will not
result in a material breach of, or constitute a material default in, any
mortgage, deed of trust, deed to secure debt, lease, promissory note, loan
agreement, credit agreement, partnership agreement, or other agreement to which
Borrower is a party or by which Borrower may be bound or affected.

      3.3   Valid and Binding Obligation. All of the Loan Documents, and all
other documents referred to herein to which Borrower is a party, upon execution
and delivery will constitute valid and binding obligations of Borrower,
enforceable against the Borrower in accordance with their terms except as
limited by Debtor Relief Laws.

      3.4   Title to the Property. Borrower holds good and marketable title to
the Property subject only to title exceptions set forth in the Title Policy.

      3.5   No Default. Borrower is not in default in the payment of the
principal of, or interest on, any material indebtedness for borrowed money, nor
is Borrower in default under any instrument or agreement under or subject to
which any material indebtedness for borrowed money has been issued, and no event
has occurred under the provisions of any such instrument which, with or without
the lapse of time or the giving of notice or both, constitutes or would
reasonably be expected to constitute an event of default of Borrower thereunder.

      3.6   Approval and Consent. No approval, authorization, or consent of any
Tribunal or Governmental Authority that has not yet been received, is required
for the proper execution, delivery, and performance of this Agreement or the
other Loan Documents.

      3.7   Cost Certification. To Borrower's Knowledge, the Approved Budget
contains, in all material respects, true and accurate cost estimates for each
line item contained therein, based upon the most complete and up-to-date
information available to Borrower on the date of this Agreement, all as more
particularly described on Exhibit B attached hereto.

within ten (10) days after written notice of such opinion from Lender, do all
things and matters reasonably necessary to assure to the reasonable satisfaction

release Lender from its obligations to make Advances hereunder; provided,
however, that during the pendency of any such contest, Borrower shall furnish to
Lender and Title Company either (x) reasonably satisfactory evidence that

      creditors or files or consent to the filing of a petition in bankruptcy or
      for protection under any Debtor Relief Laws or commence or consent to the
      commencement of any proceeding under the Federal Bankruptcy Code or any
      other federal or state law, now or hereafter in effect, relating to the
      reorganization of Borrower or Guarantor or the arrangement or
      rearrangement or readjustment of the debts of Borrower or Guarantor or
      having the effect of enjoining or staying the exercise of rights or
      remedies by creditors, it being understood that the filing against
      Borrower or Guarantor of such a petition by a partner, officer or
      stockholder of Borrower shall be deemed to be a filing with the consent of
      Borrower; if there is an attachment or sequestration of or relating to the
      Property or to any other substantial portion of any other assets of
      Borrower or Guarantor and the same is not promptly discharged;

            (j)   If Borrower shall cause, institute or fail to contest any
      proceeding for the dissolution or termination of Borrower;

            (k)   If Borrower ceases to do business or terminates its business
      as presently conducted for any reason whatsoever;

            (l)   If any condemnation, eminent domain or other taking
      proceedings shall have commenced against the Property (or any material
      portion thereof) which Lender, in its reasonable judgment, believes will
      materially and adversely affect the value of the Property;

            (m)   If any event of default shall occur under any of the Loan
      Documents (as such term may be defined therein), and such event of default
      shall continue beyond all applicable notice, grace, and cure periods; or

            (n)   Any representation or warranty made by Guarantor under the
      Guaranty is incorrect in any material respect or Guarantor is in default
      of any of Guarantor's non-monetary obligations to Lender under the
      Guaranty, and Guarantor shall fail to cure such non-monetary default
      within thirty (30) days following written notice thereof from Lender to
      Guarantor.

                                   ARTICLE VI.
                         RIGHTS AND REMEDIES OF LENDER

      6.1   Rights of Lender. Upon the occurrence of any one or more Events of
Default, Lender shall have the right, in addition to any other right or remedy
of Lender under the Loan Documents or at equity or under applicable law, but not
the obligation, in its own name or through an agent or in the name of Borrower,
to enter into possession of the Property; to perform

                                      -28-
<PAGE>

all work necessary to complete the construction and equipping of the
Improvements substantially in accordance with the Plans, Governmental
Requirements, and the requirements of any tenant lease approved by Lender; and
to do anything necessary or desirable in Lender's sole judgment to fulfill the
obligations of Borrower hereunder and under the other Loan Documents, including
the right to avail itself of, and procure performance of the Construction
Contract and subcontract or to let new or additional contracts with a new
general contractor or the same subcontractors or to others; and to employ
watchmen and other safeguards to protect the Property. Without restricting the
generality of the foregoing, and for the purposes aforesaid, Borrower hereby
appoints Lender as the attorney-in-fact of Borrower, with full power of
substitution, and in the name of Borrower, if Lender elects to do so, upon the
occurrence and continuation beyond any applicable notice, grace, or cure period
of an Event of Default, to (a) use such sums as are necessary, including any
proceeds of the Loan and the Borrower's Deposit, to make such changes or
corrections in the Plans, and employ such architects, engineers, inspectors,
rental agents, managers and contractors as may be reasonably required for the
purpose of completing the construction of the Improvements substantially in the
manner contemplated by the Plans, and Governmental Requirements, (b) execute all
applications and certificates in the name of Borrower which may be required for
completion of construction of the Improvements, (c) endorse the name of Borrower
on any checks or drafts representing proceeds of the insurance policies, or
other checks or installments payable to Borrower with respect to the Property,
(d) do every act with respect to the construction of the Improvements which
Borrower may do, (e) prosecute or defend any action or proceeding incident to
the Property, (f) to do all things reasonably necessary in Lender's reasonable
judgment, to complete construction, finishing and equipping of the Improvements
and to rent, operate and manage the Improvements, and to pay operating costs and
expenses, including management fees, of every kind and nature in connection
therewith so that the same shall be operational and usable for its intended
purpose, all in the name of Borrower, Lender or both; (g) pay interest when due
on all amounts disbursed hereunder (either by adding such interest to the
principal balance of the Loan or paying the same in cash); (h) pay, settle or
compromise all existing bills and claims which may be or become Liens or
security interests, or to avoid such bills and claims becoming Liens against the
Property or against fixtures or equipment, or as may be necessary or desirable
for the completion of construction or for the equipping and operation of the
Improvements; (i) prosecute and defend all actions or proceedings in connection
with the Property or any equipment or fixtures; (j) the right, to be exercised
in Lender's sole discretion, to terminate any remaining obligations under this
Agreement; and (k) apply for and obtain, by appropriate judicial action,
appointment of a receiver or receivers for all or any part of the Property as a
matter of right, without regard to the sufficiency of the security, without any
showing of insolvency, fraud or mismanagement on the part of Borrower and
without the necessity of filing judicial proceedings (other than for the
appointment of the receiver(s)) to protect or enforce the rights of Lender (and
Borrower hereby consents to such appointment). The power-of-attorney granted
hereby is a power coupled with an interest and is irrevocable. Lender shall have
no obligation to undertake any of the foregoing actions, and if Lender should do
so, it shall have no liability to Borrower for the sufficiency or adequacy of
any such actions taken by Lender. All reasonable cost and expenses, including
all reasonable attorneys' fees in connection with the matters contemplated in
this Section 6.1 shall be payable by Borrower on demand, and if not promptly
paid, shall be added to the principal of the Loan and shall be secured by all of
the Loan Documents. The power-of-attorney granted hereby is a power coupled with
an interest and irrevocable by action of Borrower without the joinder of Lender.
Lender shall have no obligation to undertake any of the foregoing actions,

                                      -29-
<PAGE>

and if Lender should do so, it shall have no liability to Borrower for the
sufficiency or adequacy of any such actions taken by Lender.

      6.2   Acceleration. Upon the occurrence of an Event of Default, Lender
may, at its option, declare the Loan immediately due and payable upon written
notice to Borrower, and Borrower hereby expressly waives, but not by way of
limitation, any other notice of default, notice of intent to accelerate and
notice of acceleration.

      6.3   Cessation of Advances. Upon the occurrence of an Event of Default,
the obligation of Lender to make any Advance and to make disbursements from the
Borrower's Deposit and all other obligations of Lender hereunder and under the
Loan Documents shall at Lender's option, immediately terminate; provided,
however, that nothing in this paragraph shall be deemed to limit the other
provisions of this Agreement setting forth the conditions precedent to Lender's
obligation to make any Advance or the conditions under which Lender may refuse
to make further disbursements or to limit Lender's option to make further
Advances at Lender's sole option notwithstanding the occurrence of one or more
Events of Default.

      6.4   Funds of Lender. Any funds of Lender used for any purpose referred
to in this Article VI shall constitute Advances secured by the Loan Documents
and shall bear interest at the Default Rate specified in the Note.

      6.5   No Waiver or Exhaustion. No waiver by Lender of any of its rights or
remedies hereunder, in the other Loan Documents, or otherwise, shall be
considered a waiver of any other or subsequent right or remedy of Lender; no
delay or omission in the exercise or enforcement by Lender of any rights or
remedies shall ever be construed as a waiver of any right or remedy of Lender;
and, no exercise or enforcement of any such rights or remedies shall ever be
held to exhaust any right or remedy of Lender.

      6.6   Performance by Lender. Should any covenant, duty, or agreement of
Borrower fail to be performed during the continuation of an Event of Default in
accordance with the terms of the Loan Documents, Lender may, at its option,
perform, or attempt to perform, such covenant, duty, or agreement on behalf of
Borrower. In such event, Borrower shall, at the request of Lender and promptly
pay to Lender any amount reasonably expended by Lender in such performance or
attempted performance, together with interest thereon at the Default Rate from
the date of such expenditure by Lender until paid. Notwithstanding the
foregoing, it is expressly understood that Lender does not assume and shall
never have, except by express written consent of Lender, any liability or
responsibility for the performance of any duties of Borrower hereunder or in
connection with all or any part of the Property.

      6.7   Use or Operation by Lender. Should all or any part of the Property
come into the possession of Lender, Lender may use or operate the same for the
purpose of preserving it or its value, or pursuant to the order of a court of
appropriate jurisdiction, or in accordance with any other rights held by Lender
in respect thereof. The risk of accidental loss or damage to the Property is on
Borrower, and Lender shall have no liability whatsoever for failure to obtain or
maintain insurance, or to determine whether any insurance ever in force is
adequate as to amounts or as to the risks insured, or for decline in the value
of the Property.

                                      -30-
<PAGE>

      6.8   Cumulative Rights. All rights available to Lender under the Loan
Documents shall be cumulative of and in addition to all other rights granted to
Lender at law or in equity, whether or not any sums be due and payable to Lender
and whether or not Lender shall have instituted any suit for collection,
foreclosure, or other action in connection with the Loan Documents.

      6.9   Acceptance of Assignments and Items Delivered. By acceptance of
delivery of copies of, or by taking an assignment of or security interest in,
any of the items delivered to or received by Lender pursuant to this Agreement,
including, but not limited to, the Plans, Approved Budget, and the Material
Agreements, Lender shall not be deemed to have approved same or to have assumed
any liability, obligation, or responsibility whatsoever in connection therewith
except as expressly stated in the Loan Documents.

      6.10  Delegation of Duties and Rights. Lender may exercise any of its
duties and/or exercise any of its rights under the Loan Documents by or through
its officers, directors, employees, attorneys, agents, or other representatives.

      6.11  Lender Not in Control. None of the covenants or other provisions
contained in this Agreement shall, or shall be deemed to, give Lender the right
or power to exercise control over the affairs of Borrower, the power of Lender
being limited to the right to exercise the remedies provided in this Article VI
and elsewhere in the Loan Documents.

                                  ARTICLE VII.
                          GENERAL TERMS AND CONDITIONS

      7.1   Modifications. No provision of this Agreement or the other Loan
Documents may be modified, waived, or terminated except by instrument in writing
executed by the party against whom a modification, waiver or termination is
sought to be enforced.

      7.2   Severability. In case any of the provisions of this Agreement shall
for any reason be held to be invalid, illegal, or unenforceable, such
invalidity, illegality, or unenforciability shall not affect any other provision
hereof, and this Agreement shall be construed as if such invalid, illegal, or
unenforceable provision had never been contained herein; provided, however, if
the disregard of such provision would frustrate the intent and purposes of this
Agreement. Lender may petition any court having jurisdiction in equity to render
a judgment modifying the disregarded provision(s) of this Agreement so as to
carry out such intent and purposes.

      7.3   Election of Remedies. Lender shall have all of the rights and
remedies granted in the Loan Documents in addition to such rights and remedies
that may be available to Lender at law or in equity, and these same rights and
remedies shall be cumulative and may be pursued separately, successively, or
concurrently against Borrower or any property covered under the Loan Documents
at the sole discretion of Lender. The exercise or failure to exercise any of the
same shall not constitute a waiver or release thereof or of any other right or
remedy, and such exercise or failure to exercise shall be nonexclusive.

                                      -31-
<PAGE>

      7.4   Form and Substance. All documents, certificates, insurance policies,
and other items required under this Agreement to be executed and/or delivered to
Lender shall be in form and substance satisfactory to Lender and its legal
counsel.

      7.5   Savings Clause. It is the intention to the parties hereto to comply
with all applicable federal and state laws relating to usury; that is, laws
limiting changes for the use, detention or forbearance of money and governing
contracts relating thereto; accordingly, all agreements between Borrower and
Lender, whether now existing or hereafter arising and whether written or oral,
are expressly limited so that in no contingency or event whatsoever, whether by
reason of acceleration of the maturity hereof, or otherwise, shall the amount
paid or agreed to be paid to Lender for the use, forbearance or detention of the
money to be loaned hereunder or otherwise, or for the performance or payment of
any covenant or obligation contained herein or in any other document evidencing
securing or pertaining to the Loan, exceed the Maximum Rate. If from any
circumstance whatsoever fulfillment of any provision hereof or of any such other
document, at the time performance of such provision shall be due, shall involve
transcending the limit of validity prescribed by law, then, ipso facto, the
obligation to be fulfilled shall be reduced to the limit of such validity, and
if from any such circumstance Lender shall ever receive anything of value deemed
interest by applicable law which would exceed the Maximum Rate, an amount equal
to any excessive interest shall be applied to the reduction of the principal
amount owing under the Note or on account of any other principal indebtedness of
Borrower to Lender, and not to the payment of interest, or if such excessive
interest exceeds the unpaid balance of such principal and such other
indebtedness, such excess shall be refunded to Borrower. All sums paid or agreed
to be paid to Lender for the use, forbearance or detention of the indebtedness
of Borrower to Lender shall, to the extent permitted by applicable law, be
amortized, prorated, allocated and spread throughout the full term of such
indebtedness until payment in full in such manner as permitted by law so as to
avoid any portion of the interest on the Loan becoming usurious. The terms and
provisions of this Section 7.5 shall control and supersede every other provision
of all agreements between Borrower and Lender in the event of a conflict in such
provisions.

      7.6   Rights of Third Parties. All conditions of the obligations of Lender
hereunder, including the obligation to make Advances, are imposed solely and
exclusively for the benefit of Lender and its successors and assigns and no
other person or entity shall have standing to require satisfaction of such
conditions in accordance with their terms or be entitled to assume that Lender
will refuse to make Advances in the absence of strict compliance with any or all
thereof, and no other person or entity shall, under any circumstances, be deemed
to be a beneficiary of this Agreement, any and all of the terms and conditions
of which may be freely waived in whole or in part by Lender at any time if in
its sole discretion it deems it desirable to do so, and Lender reserves the
right to enter into modifications or amendments of this Agreement with Borrower
without notification to or the consent of any other party. In particular, Lender
makes no representations and assumes no obligations as to third parties
concerning the quality of the construction of the Improvements by Borrower or
the absence therefrom of defects. In this connection Borrower agrees to and
shall indemnify, defend and hold harmless Lender from and against any
liabilities, claims or losses resulting from the disbursement of the proceeds of
the Loan or from the condition of the Property whether related to the quality of
construction or otherwise and whether arising during or after the term of the
Loan. This provision shall survive

                                      -32-
<PAGE>

the repayment of the Loan and shall continue in full force and effect so long as
the possibility of such liability, claims or losses exists.

      7.7   Evidence of Satisfaction of Conditions. Any condition of this
Agreement which requires the submission of evidence of the existence or
non-existence of a specified fact or facts implies as a condition the existence
or non-existence, as the case may be, of such fact or facts and Lender shall, at
all times, be free independently to establish to its reasonable satisfaction
such existence or non-existence.

      7.8   [Intentionally omitted]

      7.9   No Agency. Lender is not the agent or representative of Borrower,
and Borrower is not the agent or representative of Lender, and nothing in this
Agreement shall be construed to make Lender liable to anyone for goods delivered
or services performed upon the Property or for debts or claims accruing against
Borrower.

      7.10  No Partnership or Joint Venture. Nothing herein nor the acts of the
parties hereto shall be construed to create a partnership or joint venture
between Borrower and Lender.

      7.11  Number and Gender. Whenever used herein, the singular number shall
include the plural and the singular, and the use of any gender shall be
applicable to all genders. The duties, covenants, obligations, and warranties of
Borrower in this Agreement shall be joint and several obligations of Borrower,
and of each Borrower if more than one.

      7.12  Conflicts. In the event of any conflict between the provisions of
this Agreement and those of the Mortgage, the provisions of this Agreement shall
govern.

      7.13  Time of Essence. Time is of the essence in performance of this
Agreement by Borrower.

      7.14  Participation. Lender shall have the right, at its sole discretion,
to invite participants to participate in or to purchase all or portions of the
Loan.

      7.15  Further Assurances. Borrower shall do, execute, acknowledge and
deliver, at the sole cost and expense of Borrower, all and every such further
acts, deeds, conveyances, mortgages, assignments, estoppel certificates, notices
of assignment, transfers and assurances as Lender may reasonably require from
time to time in order to better assure, convey, assign, transfer and confirm
unto the Lender, the rights now or hereafter intended to be granted to the
Lender under the Loan Documents for carrying out the intention of facilitating
the performance of the terms of this Agreement.

      7.16  Captions. The captions, headings, and arrangements used in this
Agreement are for convenience only and do not in any way affect, limit, amplify,

      7.17  APPLICABLE LAW. THIS AGREEMENT AND THE LOAN DOCUMENTS SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF

                                      -33-

WITHIN SUCH STATE.

      7.18  Notices. All notices pursuant to any provisions of this Agreement or
of the other Loan Documents which require the giving of notice as a condition to
creating or effectuating an obligation of Borrower to Lender or a right on the
part of Lender to exercise rights or remedies against Borrower or any
collateral, and any notice by Borrower to Lender to the effect that Lender has
not fulfilled one or more of any obligation to Borrower under this Agreement or
under any other Loan Documents, must be in writing. Such notice shall be given
by messenger, telegram or mail (registered or certified, return receipt
requested) effective when received by the party to whom addressed or when
delivered to such address, and shall be addressed to the parties at the
addresses given below. Rejection or other refusal to accept or the inability to

to be receipt of the notice, demand or request sent. By giving at least ten (10)
days written notice thereof in the manner specified in this Section 7.18,
Borrower or Lender shall have the right from time to time and at any time during
the term of this Agreement to change their respective addresses and each shall
have the right to specify as its address any other address within the United

by Lender until the Borrower's Deposit is made by Borrower. Borrower shall
promptly notify Lender in writing if and when, to Borrower's Knowledge, the cost
of the construction of the Improvements exceeds, or appears likely to exceed,
the amount of the unadvanced portion of the Loan and the unadvanced portion of
the Borrower's Deposit.

      2.8   Direct Disbursement and Application by Lender. Lender shall have the
right, but not the obligation, following at least five (5) days' prior written
notice to Borrower, to disburse and apply the proceeds of any Advance to the
satisfaction of any of Borrower's obligations hereunder directly to Contractor,
the Title Company, and any other person or firm to whom payment is due under
this Agreement or any other Loan Documents, except with respect to any payment
contested by Borrower pursuant to Section 4.22 hereof. Any Advance by Lender for
such purpose, except Borrower's Deposit, shall be part of the Loan and shall be
secured by the Loan Documents. Subject to Borrower's right to contest a claim
pursuant to Section 4.22 hereof, Borrower hereby authorizes Lender, following at
least five (5) business days' prior written notice to Borrower, to hold. use.
disburse, and apply the Loan and the Borrower's Deposit for payment of costs of
construction of the Improvements, expenses incident to the Loan and the

Property, and the payment or performance of any obligation of Borrower
hereunder, including, without limitation, interest on the Loan, any Loan fees
owing to Lender, legal fees of Lender's attorneys which are payable by Borrower,
and such other sums as may be owing from time to time by Borrower to Lender with
respect to the Loan. Such payments may be made, at the option of Lender
following at least five (5) business days' prior written notice to Borrower, by
(a) debiting or charging Borrower's Loan account in the amount of such payments
without first disbursing such amounts to Borrower, or (b) advancing all or any
part of the amount of such payments to Borrower and then invoicing Borrower
therefor. No further direction or authorization from Borrower shall be necessary
to warrant such direct Advances and all such Advances shall satisfy pro tanto
the obligations of Lender hereunder and shall be secured by the Loan Documents
as fully as if made directly to Borrower. Notwithstanding the other provisions
of this paragraph, nothing in this Agreement is intended to be for the benefit
of, nor may be enforced by. nor should be relied upon by, any person, firm or
corporation other than Borrower.

      2.9   Advances Do Not Constitute A Waiver. No Advance shall constitute a
waiver of any of the conditions of Lender's obligations to make further Advances
nor, in the event Borrower is unable to satisfy any such condition, shall any
such waiver have the effect of precluding Lender from thereafter declaring an
Event of Default hereunder with respect to any such inability which shall
constitute an Event of Default.

      2.10  Conditions to the First Advance. As a condition precedent to the
first Advance hereunder (the "First Advance"), Borrower must satisfy the

      or entity executing and delivering such document in accordance with its
      terms. Such evidence shall include the legal opinion of legal counsel for

      Property, except as permitted herein;

            (d) Evidence that the Developer, Developer's authorized

withheld, conditioned, or delayed), to make Advances which are allocated to any
of the designated items in the Approved Budget for such other purposes or in
such different proportions as Lender may, in its reasonable discretion, deem
necessary or advisable. With the prior written consent of Lender (which consent
may not be unreasonably withheld, conditioned, or delayed), Borrower shall be
entitled to make reallocations from items in the Approved Budget for which
substantial completion has been achieved as determined by Lender and no further
funds are required, to the extent of any amount remaining in such item.

                                      -16-
<PAGE>

      2.15 Conditions Precedent for the Benefit of Lender. All conditions
precedent to the obligation of Lender to make any Advance are imposed hereby
solely for the benefit of Lender, and no other party may require satisfaction of
any such condition precedent or be entitled to assume that Lender will refuse to
make any Advance in the absence of strict compliance with such conditions
precedent. All requirements of this Agreement may be waived by Lender, in whole
or in part, at any time.

      2.16 Subordination. Lender shall not be obligated to make, nor shall
Borrower be entitled to, any Advance until such time as Lender shall have
received, to the extent requested, by Lender, subordination agreements from
Architect, Contractor, and all other persons furnishing labor, materials, or
services for the design or construction of the Improvements, subordinating to
the lien of the Mortgage any Lien, claim, or charge they may have against
Borrower or the Property.

      2.17 Interest Reserve. Borrower acknowledges and agrees that the amount of
Two Million One Hundred Seventy Thousand One Hundred Seventy-Two and No/100
Dollars ($2,170,172.00), as specified in the Approved Budget, represents
reserves for interest on the Loan (the "Interest Reserve"). So long as no Event
of Default exists and no event exists which with the giving of notice or the
passage of time or both would reasonably be expected to constitute an Event of
Default, interest due and payable under the Note may be paid from the Interest
Reserve. Borrower shall notify Lender in writing as to the amount to be
disbursed from the Interest Reserve, subject to verification by Lender. Borrower
hereby authorizes and directs Lender, and Lender shall have the right to
disburse and charge the Interest Reserve for interest due under the Loan on the
seventeenth (17th) day of each month as interest payments become due and payable
pursuant to the terms of the Loan Documents. Such disbursements shall be made by
a bookkeeping entry on Lender's records and shall be reflected as additional
Advances under the Loan, in amounts equal to the accrued interest due and
payable on the seventeenth (17th) day of each month. Such bookkeeping entry
shall be deemed to be as if Borrower had delivered a check to Lender for the
amount in question. Unless otherwise directed by Lender in its sole discretion,
the Interest Reserve shall be available only for disbursements of the periodic
payments of accrued interest due to Lender on the Loan pursuant to the terms of
this Agreement and the other Loan Documents. Any funds disbursed in the manner
provided in this Section 2.17 shall have been deemed paid to and received by
Borrower.

      2.18 Maximum Funding Obligation. Lender shall have no obligation to make
Advances in excess of amounts Borrower has properly qualified in advance to
receive, and Lender shall have no obligation to make Advances in excess of
Twenty-Eight Million Eighty-Six Thousand Four Hundred Twenty-Five and No/100
Dollars ($28,086,425.00) (the "Maximum Funding Obligation").

validity or enforceability of any of the Loan Documents, at law or in equity.
The consummation of the transactions contemplated hereby, and the performance of
any of the terms and conditions hereof and of the other Loan Documents, will not
result in a material breach of, or constitute a material default in, any
mortgage, deed of trust, deed to secure debt, lease, promissory note, loan
agreement, credit agreement, partnership agreement, or other agreement to which
Borrower is a party or by which Borrower may be bound or affected.

of, or interest on, any indebtedness for borrowed money, nor is Borrower in
default under any instrument or agreement under or subject to which any material
indebtedness for borrowed money has been issued, and no event has occurred under
the provisions of any such instrument which, with or without the lapse of time
or the giving of notice or both, constitutes or would reasonably be expected to
constitute an event of default of Borrower thereunder.

Tribunal or Governmental Authority that has not yet been received, is required
for the proper execution, delivery, and performance of this Agreement or the
other Loan Documents.

required to be filed have been filed, and no deficiency, claim, controversy or
dispute exists with respect to any federal, state, foreign, and other taxes
imposed upon Borrower, except for any such taxes as are being contested in good
faith by Borrower through appropriate proceedings.

      Guaranty, and Guarantor shall fail to cure such non-monetary default
      within thirty (30) days following written notice thereof from Lender to
      Guarantor.

                                   ARTICLE VI.
                         RIGHTS AND REMEDIES OF LENDER

      6.1 Rights of Lender. Upon the occurrence of any one or more Events of
Default, Lender shall have the right, in addition to any other right or remedy
of Lender under the Loan Documents or at equity or under applicable law, but not
the obligation, in its own name or through an agent or in the name of Borrower,
to enter into possession of the Property; to perform all work necessary to
complete the construction and equipping of the Improvements substantially in
accordance with the Plans, Governmental Requirements, and the requirements of
any tenant lease approved by Lender; and to do anything necessary or desirable
in Lender's sole judgment to fulfill the obligations of Borrower hereunder and
under the other Loan Documents, including the right to avail itself of, and
procure performance of the Construction Contract and subcontract or to let new
or additional contracts with a new general contractor or the same subcontractors
or to others; and to employ watchmen and other safeguards to protect the
Property. Without restricting the generality of the foregoing, and for the
purposes aforesaid, Borrower hereby appoints Lender as the attorney-in-fact of
Borrower, with full power of substitution, and in the name of Borrower, if
Lender elects to do so, upon the occurrence and continuation beyond any
applicable notice, grace, or cure period of an Event of Default, to (a) use such
sums as are necessary, including any proceeds of the Loan and the Borrower's
Deposit, to make such changes or corrections in the Plans, and employ such
architects, engineers, inspectors, rental agents, managers and contractors as
may be reasonably required for the purpose of completing the construction of the
Improvements substantially in the manner contemplated by the Plans, and

                                     - 28 -
<PAGE>

Governmental Requirements, (b) execute all applications and certificates in the
name of Borrower which may be required for completion of construction of the
Improvements, (c) endorse the name of Borrower on any checks or drafts
representing proceeds of the insurance policies, or other checks or installments
payable to Borrower with respect to the Property, (d) do every act with respect
to the construction of the Improvements which Borrower may do, (e) prosecute or
defend any action or proceeding incident to the Property, (f) to do all things
reasonably necessary in Lender's reasonable judgment, to complete construction,
finishing and equipping of the Improvements and to rent, operate and manage the
Improvements, and to pay operating costs and expenses, including management
fees, of every kind and nature in connection therewith so that the same shall be
operational and usable for its intended purpose, all in the name of Borrower,
Lender or both; (g) pay interest when due on all amounts disbursed hereunder
(either by adding such interest to the principal balance of the Loan or paying
the same in cash); (h) pay, settle or compromise all existing bills and claims
which may be or become Liens or security interests, or to avoid such bills and
claims becoming Liens against the Property or against fixtures or equipment, or
as may be necessary or desirable for the completion of construction or for the
equipping and operation of the Improvements; (i) prosecute and defend all
actions or proceedings in connection with the Property or any equipment or
fixtures; (j) the right, to be exercised in Lenders sole discretion, to
terminate any remaining obligations under this Agreement; and (k) apply for and
obtain, by appropriate judicial action, appointment of a receiver or receivers
for all or any part of the Property as a matter of right, without regard to the
sufficiency of the security, without any showing of insolvency, fraud or
mismanagement on the part of Borrower and without the necessity of filing
judicial proceedings (other than for the appointment of the receiver(s)) to
protect or enforce the rights of Lender (and Borrower hereby consents to such
appointment). The power-of-attorney granted hereby is a power coupled with an
interest and is irrevocable. Lender shall have no obligation to undertake any of
the foregoing actions, and if Lender should do so, it shall have no liability to
Borrower for the sufficiency or adequacy of any such actions taken by Lender.
All reasonable cost and expenses, including all reasonable attorneys' fees in
connection with the matters contemplated in this Section 6.1 shall be payable by
Borrower on demand, and if not promptly paid, shall be added to the principal of
the Loan and shall be secured by all of the Loan Documents. The
power-of-attorney granted hereby is a power coupled with an interest and
irrevocable by action of Borrower without the joinder of Lender. Lender shall
have no obligation to undertake any of the foregoing actions, and if Lender
should do so, it shall have no liability to Borrower for the sufficiency or
adequacy of any such actions taken by Lender.

      6.2 Acceleration. Upon the occurrence of an Event of Default, Lender may,
at its option, declare the Loan immediately due and payable upon written notice
to Borrower, and Borrower hereby expressly waives, but not by way of limitation,
any other notice of default, notice of intent to accelerate and notice of
acceleration.

      6.3 Cessation of Advances. Upon the occurrence of an Event of Default, the
obligation of Lender to make any Advance and to make disbursements from the
Borrower's Deposit and all other obligations of Lender hereunder and under the
Loan Documents shall at Lender's option, immediately terminate; provided,
however, that nothing in this paragraph shall be deemed to limit the other
provisions of this Agreement setting forth the conditions precedent to Lender's
obligation to make any Advance or the conditions under which Lender may refuse
to

                                     - 29 -
<PAGE>

make further disbursements or to limit Lender's option to make further Advances
at Lender's sole option notwithstanding the occurrence of one or more Events of
Default.

      6.4 Funds of Lender. Any funds of Lender used for any purpose referred to
in this Article VI shall constitute Advances secured by the Loan Documents and
shall bear interest at the Default Rate specified in the Note.

      6.5 No Waiver or Exhaustion. No waiver by Lender of any of its rights or
remedies hereunder, in the other Loan Documents, or otherwise, shall be
considered a waiver of any other or subsequent right or remedy of Lender; no
delay or omission in the exercise or enforcement by Lender of any rights or
remedies shall ever be construed as a waiver of any right or remedy of Lender;
and, no exercise or enforcement of any such rights or remedies shall ever be
held to exhaust any right or remedy of Lender.

      6.6 Performance by Lender. Should any covenant, duty, or agreement of
Borrower fail to be performed during the continuation of an Event of Default in
accordance with the terms of the Loan Documents, Lender may, at its option,
perform, or attempt to perform, such covenant, duty, or agreement on behalf of
Borrower. In such event, Borrower shall, at the request of Lender and promptly
pay to Lender any amount reasonably expended by Lender in such performance or
attempted performance, together with interest thereon at the Default Rate from
the date of such expenditure by Lender until paid. Notwithstanding the
foregoing, it is expressly understood that Lender does not assume and shall
never have, except by express written consent of Lender, any liability or
responsibility for the performance of any duties of Borrower hereunder or in
connection with all or any part of the Property.

      6.7 Use or Operation by Lender. Should all or any part of the Property
come into the possession of Lender, Lender may use or operate the same for the
purpose of preserving it or its value, or pursuant to the order of a court of
appropriate jurisdiction, or in accordance with any other rights held by Lender
in respect thereof. The risk of accidental loss or damage to the Property is on
Borrower, and Lender shall have no liability whatsoever for failure to obtain or
maintain insurance, or to determine whether any insurance ever in force is
adequate as to amounts or as to the risks insured, or for decline in the value
of the Property.

      6.8 Cumulative Rights. All rights available to Lender under the Loan
Documents shall be cumulative of and in addition to all other rights granted to
Lender at law or in equity, whether or not any sums be due and payable to Lender
and whether or not Lender shall have instituted any suit for collection,
foreclosure, or other action in connection with the Loan Documents.

      6.9 Acceptance of Assignments and Items Delivered. By acceptance of
delivery of copies of, or by taking an assignment of or security interest in,
any of the items delivered to or received by Lender pursuant to this Agreement,
including, but not limited to, the Plans, Approved Budget, and the Material
Agreements, Lender shall not be deemed to have approved same or to have assumed
any liability, obligation, or responsibility whatsoever in connection therewith
except as expressly stated in the Loan Documents.

                                     - 30 -
<PAGE>

      6.10 Delegation of Duties and Rights. Lender may exercise any of its
duties and/or exercise any of its rights under the Loan Documents by or through
its officers, directors, employees, attorneys, agents, or other representatives.

      6.11 Lender Not in Control. None of the covenants or other provisions
contained in this Agreement shall, or shall be deemed to, give Lender the right
or power to exercise control over the affairs of Borrower, the power of Lender
being limited to the right to exercise the remedies provided in this Article VI
and elsewhere in the Loan Documents.

                                  ARTICLE VII.
                          GENERAL TERMS AND CONDITIONS

      7.1 Modifications. No provision of this Agreement or the other Loan
Documents may be modified, waived, or terminated except by instrument in writing
executed by the party against whom a modification, waiver or termination is
sought to be enforced.

      7.2 Severability. In case any of the provisions of this Agreement shall
for any reason be held to be invalid, illegal, or unenforceable, such
invalidity, illegality, or unenforceability shall not affect any other provision
hereof, and this Agreement shall be construed as if such invalid, illegal, or
unenforceable provision had never been contained herein; provided, however, if
the disregard of such provision would frustrate the intent and purposes of this
Agreement, Lender may petition any court having jurisdiction in equity to render
a judgment modifying the disregarded provision(s) of this Agreement so as to
carry out such intent and purposes.

      7.3 Election of Remedies. Lender shall have all of the rights and remedies
granted in the Loan Documents in addition to such rights and remedies that may
be available to Lender at law or in equity, and these same rights and remedies
shall be cumulative and may be pursued separately, successively, or concurrently
against Borrower or any property covered under the Loan Documents at the sole
discretion of Lender. The exercise or failure to exercise any of the same shall
not constitute a waiver or release thereof or of any other right or remedy, and
such exercise or failure to exercise shall be nonexclusive.

      7.4 Form and Substance. All documents, certificates, insurance policies,
and other items required under this Agreement to be executed and/or delivered to
Lender shall be in form and substance satisfactory to Lender and its legal
counsel.

      7.5 Savings Clause. It is the intention to the parties hereto to comply
with all applicable federal and state laws relating to usury; that is, laws
limiting changes for the use, detention or forbearance of money and governing
contracts relating thereto; accordingly, all agreements between Borrower and
Lender, whether now existing or hereafter arising and whether written or oral,
are expressly limited so that in no contingency or event whatsoever, whether by
reason of acceleration of the maturity hereof, or otherwise, shall the amount
paid or agreed to be paid to Lender for the use, forbearance or detention of the
money to be loaned hereunder or otherwise, or for the performance or payment of
any covenant or obligation contained herein or in any other document evidencing
securing or pertaining to the Loan, exceed the Maximum Rate. If from any
circumstance whatsoever fulfillment of any provision hereof or of any such other
document, at the time performance of such provision shall be due, shall involve

                                      -31-
<PAGE>

transcending the limit of validity prescribed by law, then, ipso facto, the
obligation to be fulfilled shall be reduced to the limit of such validity, and
if from any such circumstance Lender shall ever receive anything of value deemed
interest by applicable law which would exceed the Maximum Rate, an amount equal
to any excessive interest shall be applied to the reduction of the principal
amount owing under the Note or on account of any other principal indebtedness of
Borrower to Lender, and not to the payment of interest, or if such excessive
interest exceeds the unpaid balance of such principal and such other
indebtedness, such excess shall be refunded to Borrower. All sums paid or agreed
to be paid to Lender for the use, forbearance or detention of the indebtedness
of Borrower to Lender shall, to the extent permitted by applicable law, be
amortized, prorated, allocated and spread throughout the full term of such
indebtedness until payment in full in such manner as permitted by law so as to
avoid any portion of the interest on the Loan becoming usurious. The terms and
provisions of this Section 7.5 shall control and supersede every other provision
of all agreements between Borrower and Lender in the event of a conflict in such
provisions.

      7.6 Rights of Third Parties. All conditions of the obligations of Lender
hereunder, including the obligation to make Advances, are imposed solely and
exclusively for the benefit of Lender and its successors and assigns and no
other person or entity shall have standing to require satisfaction of such
conditions in accordance with their terms or be entitled to assume that Lender
will refuse to make Advances in the absence of strict compliance with any or all
thereof, and no other person or entity shall, under any circumstances, be deemed
to be a beneficiary of this Agreement, any and all of the terms and conditions
of which may be freely waived in whole or in part by Lender at any time if in
its sole discretion it deems it desirable to do so, and Lender reserves the
right to enter into modifications or amendments of this Agreement with Borrower
without notification to or the consent of any other party. In particular, Lender
makes no representations and assumes no obligations as to third parties
concerning the quality of the construction of the Improvements by Borrower or
the absence therefrom of defects. In this connection Borrower agrees to and
shall indemnify, defend and hold harmless Lender from and against any
liabilities, claims or losses resulting from the disbursement of the proceeds of
the Loan or from the condition of the Property whether related to the quality of
construction or otherwise and whether arising during or after the term of the
Loan. This provision shall survive the repayment of the Loan and shall continue
in full force and effect so long as the possibility of such liability, claims or
losses exists.

      7.7 Evidence of Satisfaction of Conditions. Any condition of this
Agreement which requires the submission of evidence of the existence or
non-existence of a specified fact or facts implies as a condition the existence
or non-existence, as the case may be, of such fact or facts and Lender shall, at
all times, be free independently to establish to its reasonable satisfaction
such existence or non-existence.

      7.8 [Intentionally omitted]

      7.9 No Agency. Lender is not the agent or representative of Borrower, and
Borrower is not the agent or representative of Lender, and nothing in this
Agreement shall be construed to make Lender liable to anyone for goods delivered
or services performed upon the Property or for debts or claims accruing against
Borrower.

                                      -32-
<PAGE>

      7.10 No Partnership or Joint Venture. Nothing herein nor the acts of the
parties hereto shall be construed to create a partnership or joint venture
between Borrower and Lender.

      7.11 Number and Gender. Whenever used herein, the singular number shall
include the plural and the singular, and the use of any gender shall be
applicable to all genders. The duties, covenants, obligations, and warranties of
Borrower in this Agreement shall be joint and several obligations of Borrower,
and of each Borrower if more than one.

      7.12 Conflicts. In the event of any conflict between the provisions of
this Agreement and those of the Mortgage, the provisions of this Agreement shall
govern.

      7.13 Time of Essence. Time is of the essence in performance of this
Agreement by Borrower.

      7.14 Participation. Lender shall have the right, at its sole discretion,
to invite participants to participate in or to purchase all or portions of the
Loan.

      7.15 Further Assurances. Borrower shall do, execute, acknowledge and
deliver, at the sole cost and expense of Borrower, all and every such further
acts, deeds, conveyances, mortgages, assignments, estoppel certificates, notices
of assignment, transfers and assurances as Lender may reasonably require from
time to time in order to better assure, convey, assign, transfer and confirm
unto the Lender, the rights now or hereafter intended to be granted to the
Lender under the Loan Documents for carrying out the intention of facilitating
the performance of the terms of this Agreement.

      7.16 Captions. The captions, headings, and arrangements used in this
Agreement are for convenience only and do not in any way affect, limit, amplify,

      7.17 APPLICABLE LAW. THIS AGREEMENT AND THE LOAN DOCUMENTS SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS AND
THE LAWS OF THE UNITED STATES APPLICABLE TO TRANSACTIONS WITHIN SUCH STATE.

      7.18 Notices. All notices pursuant to any provisions of this Agreement or
of the other Loan Documents which require the giving of notice as a condition to
creating or effectuating an obligation of Borrower to Lender or a right on the
part of Lender to exercise rights or remedies against Borrower or any
collateral, and any notice by Borrower to Lender to the effect that Lender has
not fulfilled one or more of any obligation to Borrower under this Agreement or
under any other Loan Documents, must be in writing. Such notice shall be given
by messenger, telegram or mail (registered or certified, return receipt
requested) effective when received by the party to whom addressed or when
delivered to such address, and shall be addressed to the parties at the
addresses given below. Rejection or other refusal to accept or the inability to
deliver because of changed address of which no notice was given shall be deemed
to be receipt of the notice, demand or request sent. By giving at least ten (10)
days written notice thereof in the manner specified in this Section 7.18,
Borrower or Lender shall have the right from time to time and at any time during
the term of this Agreement to change their respective addresses and each

                                      -33-

shall have the right to specify as its address any other address within the
