by the Bank, promptly pay to the Bank such amount as is necessary to give effect
to such change.

warranties contained herein have been made after diligent inquiry calculated to

                                   ARTICLE IV

                              COVENANTS OF BORROWER

         Borrower covenants with Bank as follows:

         Section 4.01. No Conveyances or Encumbrances. (a) It will not sell,
lease, mortgage, assign, pledge, convey or encumber the Project or any part
thereof or interest therein in any way without the prior written consent of Bank
excepting, however, the leasing of a portion of the Project to CTI PET Systems,
Inc., an affiliate of Borrower. All easements and restrictive covenants not
already in existence at the Closing Date affecting the Land shall be submitted
to Bank for its approval prior to the execution thereof by Borrower, accompanied
by a drawing or survey showing the location thereof.

         (b) The Borrower will promptly pay and discharge all claims and liens
for labor done and materials and services furnished in connection with the
construction of the Improvements. The Borrower will have the right to contest in
good faith any claim or lien, provided that it does so diligently and without
prejudice to the Bank. Upon the Bank's request, the Borrower will promptly
provide a bond, cash deposit, or other security reasonably satisfactory to the
Bank to protect the Bank's interest and security, should the contest be
unsuccessful.

         Section 4.02. Compliance With Law. It will comply promptly with all
existing and future applicable laws, ordinances, rules and regulations of all
governmental, judicial or other legal authorities having jurisdiction over the
Land or the Improvements and it will comply with all recorded restrictions
affecting the Property.

         Section 4.03. Inspections. (a) It will permit Bank, or its
representatives, and Bank's Architect to enter upon the Land, inspect the
Project and all materials to be used in

                                       14
<PAGE>

the construction thereof and to examine all detailed plans and shop drawings
which are or may be kept at the construction site and will cooperate, and cause
the General Contractor to cooperate, with Bank and Bank's Architect to enable
him to perform his functions hereunder. The Borrower agrees to bear the cost,
expense or fee of such inspections.

         (b) If the Bank determines in good faith that any work or materials do
not conform to the approved Plans and Specifications or sound building practice
or otherwise materially depart from any of the requirements of this Agreement,
the Bank may require the work to be stopped and may withhold disbursements until
the matter is corrected to the reasonable satisfaction of Bank. In that event,
the Borrower will promptly correct the work to the Bank's reasonable
satisfaction. No such action by the Bank will affect the Borrower's obligation
to complete the Improvements on or before the Completion Date.

         (c) The Bank is under no duty to supervise or inspect the construction
or examine any books and records. Any inspection or examination by the Bank is
for the sole purpose of protecting the Bank's security and preserving the Bank's
rights under this Agreement and the other Loan Documents. No default of the
Borrower will be waived by any inspection by the Bank. In no event will any
inspection by the Bank be a representation that there has been or will be
compliance with the Plans and Specifications or that the construction is free
from defective materials or workmanship.

         Section 4.04. Payment of Costs. It will pay to Bank at closing, and
thereafter upon demand, all fees, charges and expenses incurred by Bank
(including Bank's reasonable attorneys' fees, court costs, etc.) in connection
with the Loan.

         Section 4.05. Construction of the Project. It agrees to begin
construction of the Improvements promptly after the Closing Date and to
prosecute diligently and continuously the construction of the Improvements in
accordance with the Plans and Specifications so that the Improvements are fully
complete and ready for use and occupancy on or before the Completion Date.
Pursuant to Section 6.01 (e) on or before the date hereof, a master set of the
Plans and Specifications shall be delivered to the Bank, each page of which
shall be initialed or otherwise identified and approved by the Bank and the
Borrower, which master set shall govern all questions that may arise with
respect thereto. All requests for material changes in the Plans and
Specifications must be made in writing by the Borrower according to the terms of
Section 4.10 below.

         Section 4.06. Satisfaction of Conditions. It will cause all conditions
hereof to be satisfied to the extent it is within its power to do so.

         Section 4.07. Use of Loan Proceeds. Borrower shall use the Loan
proceeds only for the following purposes: (i) acquisition of the Land, (ii)
Construction Costs approved by Bank, (iii) payment of any fees, charges or
expenses related to the Project, (iv) such other purposes as may be approved in
advance in writing by Bank and (v), at the option of the Bank, accrued interest
upon unpaid Loan advances. Borrower shall furnish to Bank, promptly after Bank's
request therefore, evidence satisfactory to Bank that all Loan proceeds have
actually been paid or applied by Borrower for the purposes specified in this
Section.

         Section 4.08. Indemnification. It will indemnify Bank from claims of
brokers arising by reason of the execution hereof or the consummation of the
transactions contemplated hereby. The Borrower also agrees to indemnify the Bank
and hold it harmless from and against all liabilities, claims, damages, costs,
and expenses (including, but not limited to, reasonable legal fees, court costs
and disbursements) arising out of, or resulting from, any defective workmanship
or materials occurring in the construction of the Improvements. Upon demand by
the Bank, the Borrower will defend any action or proceeding brought against the
Bank alleging any defective workmanship or materials, or the Bank may elect to
conduct its own defense at the expense of the Borrower. The provisions of this
Section will survive the termination of this Agreement and the payment and
performance of the Obligations.

         Section 4.09. Correction of Defects. It will, upon demand of Bank's
Architect, correct any structural defect in the Improvements or any material
departure from the Plans and Specifications not approved by Bank's Architect,
and the advance of and proceeds of the Loan shall not constitute a waiver of
Bank's right to require compliance with this covenant with respect to any such
defects or departures from the Plans and Specifications not theretofore
discovered by, or called to the attention of, Bank's Architect.

         Section 4.10. Change Orders. It will not enter into any Change Order in
an amount in excess of $50,000 or an aggregate of Change Orders during the
construction period in an amount in excess of $150,000 except with the prior
written consent of Bank. The Borrower shall be required to provide Bank notice
of each Change Order after Change Orders have been made in an aggregate amount
equal to $50,000. The Borrower must also obtain the Bank's prior written
approval of any material change in the Plans and Specifications for the
Improvements approved by the Bank that might adversely affect the value of the
Bank's security. The Borrower must also obtain all approvals of any changes in
plans, specifications, work, materials, or contracts that are required by law or
under the terms of any recorded instrument affecting the Project or under any
lease, loan commitment, or other agreement relating to the Project. The Bank
will have a reasonable time to evaluate any requests for its approval of any
changes referred to in this Section, and the Bank will not be required to
consider approving any changes unless all other approvals that are required from
other parties have been obtained. The Bank may approve or disapprove changes in
its reasonable discretion.

         Section 4.11. Right to Cure. Bank may apply amounts due hereunder to
the satisfaction of the conditions hereof, and amounts so applied shall be part
of the Loan, shall be evidenced by and accrue interest at the rate set forth in
the Note and shall be secured by the Deed of Trust.

         Section 4.12. No Other Contracts. It will not execute any material
contract or become party to any material arrangement for the acquisition,
construction or equipping of the Project unless (a) such contract or arrangement
is approved in writing by Bank, (b) Borrower delivers to Bank a photocopy of the
fully executed contract or other document evidencing the arrangement, and (c) if
requested by the Bank, Borrower delivers to Bank

                                       16
<PAGE>

a performance and payment bond, with surety satisfactory to Bank, in the amount
of the contract price, in such form as Bank may require and naming Bank as
co-obligee.

         Section 4.13. Project Information. It shall provide Bank with such
information and documentation with respect to the construction, ownership and
operation of the Project as Bank may reasonably require from time to time during
the term of the Loan.

         Section 4.14. Receipts. It will deliver to Bank, upon Bank's reasonable
demand, any contracts, bills of sale, statements, receipted vouchers or
agreements under which Borrower claims title to any materials, fixtures or
articles incorporated in the Improvements or subject to the lien of the Deed of
Trust. In addition, Borrower shall furnish to Bank, whenever reasonably
requested to do so, satisfactory evidence showing that all moneys theretofore
advanced or paid by Bank on account of the Loan have actually been paid or
applied by Borrower for the purposes represented.

         Section 4.15. Insurance. It will keep the Project in good repair,
maintain insurance on its property in such amounts and against such risks as is
customarily maintained by similar businesses operating in the same vicinity,
promptly deliver to the Bank true copies of all renewal and replacement
insurance policies and, within 10 days after notice in writing from the Bank,
obtain such additional insurance as the Bank may reasonably request. Upon the
request of the Bank, any insurance policy insuring the Project must name the
Bank as mortgagee, loss payee and additional insured and require that all net
proceeds from any claim in excess of $50,000 are paid to the Bank. The proceeds
of insurance will be applied as provided by the Deed of Trust. Each policy shall
contain an undertaking by the insurer that such policy shall not be modified
adversely to the interests of the Bank or canceled without at least 30 days'
prior written notice to the Bank. All such policies shall be deposited with the
Bank, provided that in lieu of such policies there may be deposited with the
Bank a certificate or certificates of the respective insurers attesting the fact
that the insurance required by this Section is in force and effect. If requested
by the Bank, the Borrower shall furnish to the Bank prior to the Closing Date
and annually thereafter a certificate of a person selected by the Borrower and
knowledgeable in the insurance business who is not an officer, partner, member
or employee of the Borrower reciting that all policies required to be in effect
at that time are in full force and effect and that the amounts and types of
insurance evidenced thereby comply with and satisfy all the requirements of this
Section. Prior to the expiration of any such policy, the Borrower shall furnish
the Bank evidence satisfactory to the Bank that the policy has been renewed or
replaced or is no longer required by this Agreement.

         Section 4.16. Payment of Charges. Borrower shall pay all insurance
premiums, taxes, assessments and other charges that have or will become liens or
encumbrances upon the Project or any part thereof.

         Section 4.17. Books and Records. The Borrower will maintain full and
correct books and records in accordance with GAAP showing in detail the earnings
and expenses relating to the Project and will permit representatives of the Bank
to examine such books and records and all supporting vouchers and data at any
time and from time to time as the

                                       17
<PAGE>

Bank may reasonably request at such place in the vicinity of the Project as such
books and records are customarily kept.

         Section 4.18. Eminent Domain: Condemnation. In the event that any
proceedings to take the Project or any part thereof by exercise of the power of
eminent domain are undertaken or threatened, the Borrower will give the Bank
prompt notice thereof. Any award made to the Borrower will be paid to the Bank,
and the Borrower hereby appoints the Bank its attorney-in-fact to receive and
give all appropriate discharges for any such award. Any such award may, at the
option of the Bank, be applied to (a) the prepayment of the principal of the
Note in inverse order of maturity of any installments thereof or (b) the payment
of accrued interest, if any, or (c) be released to the Borrower in whole or in
part upon conditions satisfactory to the Bank. Upon any default hereunder, all
of the Borrower's rights, title and interest in and to all such awards are
hereby assigned to the Bank. Upon payment of accrued interest and the unpaid
principal balance of the Note and all other Obligations, the Borrower will be
entitled to the remaining balance, if any, of any such award.

         Section 4.19. Financial Covenants. Borrower shall maintain the
financial covenants set forth in the Revolving Credit Loan Agreement, all of
which are incorporated herein by reference as if fully set forth herein, and

                         ADDITIONAL CONDITIONS OF BANK'S
                           OBLIGATION TO MAKE ADVANCES

         Section 7.01. General Provisions Regarding Disbursement of Loans. If
all conditions precedent to the advance have been performed to the satisfaction
of the Bank, the Bank shall make advances for payment of the Construction Costs
into the Construction Disbursement Account or payable to the Borrower, or
jointly to the Borrower and the General Contractor (or other appropriate
subcontractors), or, after a default or an event which with notice or lapse of
time or both could constitute a default hereunder, in such other manner as the
Bank may elect; provided, however, the Bank shall in no event be required to
make any advance based on a percentage of completion greater than that estimated
by the Bank's Architect, and provided further, the Bank may, at its option, (a)
retain the Retainage until completion of the Improvements and/or issuance of the
certificate of occupancy and (b) withhold an additional amount of the Loan
sufficient to cover the unpaid balance of the Construction Costs and to complete
construction. The proceeds of each advance hereunder shall be applied solely and
exclusively to payment, or reimbursement to the Borrower for payment, of the
Construction Costs and the application for such advance. The Bank may also
elect, without further notice to or authorization by the Borrower, to use the
Loan proceeds to pay, as and when due, any Loan fees owing to the Bank, interest
on the Loan, release charges under prior deeds of trust on the Land, legal fees
and disbursements of the Bank's attorneys that are payable by the Borrower, and
any other sums with respect to

                                       24
<PAGE>

the Loan that may be owing from time to time by the Borrower to the Bank. These
payments may be made, at the option of the Bank, by (i) debiting or charging the
Loan proceeds in the amount of the payments without first disbursing that amount
into the Construction Disbursement Account, or (ii) disbursing all or any part
of the amount of the payments into the Borrower's Construction Disbursement
Account and then debiting that account for those payments or invoicing the
Borrower therefor. Each advance whether made to the Borrower or in any other
manner permitted hereby, shall be deemed to be an advance under the Note and
shall be secured by the Deed of Trust.

         The Bank shall not be required to make any advance of the Loan if, in
the opinion of the Bank, (a) the amount of such Loan advance shall (i) together
with all Loan amounts previously advanced hereunder and applied to the
Construction Costs, be greater than the Construction Costs (as estimated from
time to time by the Bank's Architect and the Bank) incurred by the Borrower to
the date of the requested Loan advance, or (ii) together with the balance of the
Loan, be less than the amount of the Construction Costs (as estimated by the
Bank's Architect and the Bank) of completing the Improvements, (b) the
representations made and the information furnished by the Borrower to the Bank
with regard to the Loan and the Borrower's qualification therefor shall not have
been or not continue to be true and not misleading in all material respects, (c)
any Event of Default or any event which with notice or lapse of time or both
could constitute an Event of Default shall exist hereunder or (d) all conditions
precedent to all prior Loan advances shall not have been or continue to be
satisfied or shall not have been waived in writing by the Bank. The Bank shall
have no obligation to advance Loan proceeds more than once per month unless
otherwise permitted by the Bank.

         The Borrower's Requisition shall constitute a representation by the
Borrower to the Bank that the monies therein referred to have been or are to be
used in the construction of the Improvements, and the Bank shall be entitled to
rely thereon and shall be held harmless for all liability in connection
therewith. The payment of any Requisition maybe made upon such additional terms
and conditions as may be deemed appropriate and reasonable by the Bank.

         If the Bank makes Loan advances before they are due in accordance with
the schedule of payments because the Bank believes it advisable to do so, such
Loan advances shall be deemed to be made in pursuance and not in modification
hereof, but the making of any such Loan advance or part thereof shall not be
deemed an approval or acceptance by the Bank of the work done on the
Improvements prior thereto.

         Bank's obligation to make each Loan advance hereunder shall be subject
to the satisfaction (as determined in the sole discretion of Bank) or written
waiver by Bank of the following additional conditions:

         (a)      all conditions of the first Loan advance shall have been and
remain satisfied;

be delivered to Bank an endorsement to the Mortgagee Title Policy (i) advancing

acknowledging liability of the Title Company in an amount equal to all prior
Loan advances (if any) plus the requested Loan advance and (iii) reflecting that
subsequent to the last preceding Loan advance there has been no change in the
status of title and that no survey or other exceptions not previously approved
by Bank have arisen;

         (g)      if requested by the Bank, Borrower shall deliver or cause to
be delivered to Bank a sworn statement of Borrower that, to the best of its
knowledge, at the time of the Loan advance (i) there are no uncured defaults

both, would give rise to or constitute such a default, (ii) each of the
representations and warranties made by Borrower herein are true and correct as
of the date of such Loan advance and (iii) Borrower's financial condition has
not changed materially and adversely from that set forth in Borrower's most
recent financial statements delivered to Bank; and

and substance satisfactory to Bank and its counsel, properly executed and duly
recorded or filed (as applicable), and all approvals to be given by Bank
hereunder shall be at the sole reasonable discretion of Bank and no changes or

hereunder) without the prior written consent of Bank;

         (f)      If requested by the Bank, waivers by the General Contractor

         (b)      all breaches or violations of this Agreement (other than an
Event of Default) or any event that would become a breach or violation (other
than an Event of Default) upon notice or lapse of time or both under any of the
terms or provisions of any note, or of any other evidence of Indebtedness or
agreement or contract governing the borrowing of money by the Borrower; and

         (c)      levy of an attachment, execution or other process against any
of the property or assets, real or personal, of the Borrower, which property and
assets in the aggregate have a book value or fair market value in excess of
$100,000.

         Section 9.05. Maintenance of Property. Maintain all of its properties
and assets in good condition, repair and working order, ordinary wear and tear
excepted.

         Section 9.06. Compliance with Laws. Comply in all material respects
with all laws and governmental regulations of the United States of America and
all political subdivisions thereof applicable to the rights of the Borrower to
transact business under any such laws and regulations, including, without
limitation, all applicable federal, state

                                       29
<PAGE>

and local laws and regulations relating to environmental matters, including,
without limitation, air and water pollution and safety, health and
discrimination, the noncompliance with which would have a material adverse
effect on the business, properties or financial condition of the Borrower or the
Borrower's ability to perform its obligations hereunder.

         Section 9.07. Indemnity by Borrower. Indemnify, save, and hold harmless
the Bank and its directors, officers, agents, attorneys, and employees
(collectively, the "Indemnitees") from and against: (i) any and all claims,
demands, actions, or causes of action that are asserted against any Indemnitee
by any Person if the claim, demand, action, or cause of action directly or
indirectly relates to a claim, demand, action, or cause of action that the
Person asserts or may assert against Borrower, any affiliate of Borrower or any
officer, director, shareholder or member of Borrower, as applicable, (ii) any
and all claims, demands, actions or causes of action that are asserted against
any Indemnitee if the claim, demand, action or cause of action directly or
indirectly relates to this Agreement, the use of proceeds of the Note, or the
relationship of Borrower and Bank under this Agreement or any other Loan
Document or any transaction contemplated pursuant to this Agreement or any other
Loan Document, (iii) any administrative or investigative proceeding by any
governmental authority directly or indirectly related to a claim, demand, action
or cause of action described in clauses (i) or (ii) above, and (iv) any and all
liabilities, losses, costs, or expenses (including reasonable attorneys' fees,
court costs and disbursements) that any Indemnitee suffers or incurs as a result
of any of the foregoing; provided, however, that Borrower shall have no
obligation under this Section to the Bank with respect to any of the foregoing
arising out of the gross negligence or willful misconduct of the Bank or the
breach by the Bank of this Agreement or any other Loan Document or from the
transfer or disposition of the Note by the Bank. If any claim, demand, action or
cause of action is asserted against any Indemnitee, such Indemnitee shall
promptly notify Borrower, but the failure to so promptly notify Borrower shall
not affect Borrower's obligations under this Section unless such failure
materially prejudices Borrower's right to participate in the contest of such
claim, demand, action or cause of action, as hereinafter provided. If requested
by Borrower in writing and so long as no Event of Default shall have occurred
and be continuing, such Indemnitee shall in good faith contest the validity,
applicability and amount of such claim, demand, action or cause of action and
shall permit Borrower to participate in such contest. Any Indemnitee that
proposes to settle or compromise any claim or proceeding for which Borrower may
be liable for payment of indemnity hereunder shall give Borrower written notice
of the terms of such proposed settlement or compromise reasonably in advance of
settling or compromising such claim or proceeding and shall obtain Borrower's
concurrence thereto. Each Indemnitee is authorized to employ counsel at the
expense of the Borrower in enforcing its rights hereunder and in defending
against any claim, demand, action, or cause of action covered by this Section;
provided, however, that each Indemnitee shall endeavor, but shall not be
obligated, in connection with any matter covered by this Section which also
involves other Indemnitees, to use reasonable efforts to avoid unnecessary
duplication of effort by counsel for all Indemnitees. Any obligation or
liability of Borrower to any Indemnitee under this Section shall survive the
expiration or termination of this Agreement and the other Loan Documents and the
repayment of the Obligations.

                               NEGATIVE COVENANTS

         The Borrower agrees that until payment and performance in full of the
Obligations, without the prior written consent of the Bank, the Borrower shall
not:

         Section 10.01. Negative Pledge. Create, incur, assume or suffer to come
into existence after the date hereof any mortgage, pledge or other encumbrance
upon any of its property or assets whether now owned or thereafter arising or
acquired other than Permitted Encumbrances.

         Section 10.02. Breach or Violation. Enter into any agreement containing
any provision that would be violated or breached by the performance of the
Borrower's obligations under this Agreement or any other Loan Document.

         Section 10.03. Restrictions on Indebtedness. Create, incur, assume or
suffer to exist any Indebtedness, except that Indebtedness permitted pursuant to
the terms of the Revolving Credit Loan Agreement, which terms are incorporated
herein by reference as if fully set forth herein.

                                   ARTICLE XI

                               GENERAL CONDITIONS

         Section 11.01. Third Parties; Benefit; Miscellaneous. All obligations
of Borrower set forth in the Loan Documents are imposed solely for the benefit
of Bank, its successors and assigns, and no other Person shall be deemed to be a
beneficiary of such obligations or be entitled to require satisfaction of such
obligations in accordance with their terms or to assume that Bank will require
strict compliance therewith. The terms and provisions of the Loan Documents are
for the benefit of the parties hereto and no other Person shall have any right
or cause of action on account thereof. Bank shall in no event be liable to any
Person other than Borrower for any advance of Loan proceeds and no contractor,
subcontractor, materialman or other Person (including, without limitation, the
General Contractor) shall have any right or claim against Bank pursuant to this
Agreement, any such Loan Document, or the administration of the Loan. Nothing
contained in the Loan Documents shall be construed to create any relationship
between Borrower and Bank other than the relationship of debtor and lender. By
accepting or approving anything required to be observed, performed or fulfilled
by Borrower, or to be given to Bank pursuant to the terms of the Loan Documents,
Bank shall not be deemed to have warranted or represented the sufficiency,
legality, effectiveness or legal effect of the same, or of any term, provision
or condition thereof, and such acceptance or approval thereof shall not
constitute any warranty or representation to any party with respect thereto by
Bank.

         Section 11.02. Liability of Bank. Bank shall not be liable for any act
or omission by it pursuant to the provisions of the Loan Documents in the
absence of fraud, willful malfeasance, gross negligence or breach of contract.
Bank shall incur no liability to

                                       31
<PAGE>

Borrower or any other Person in connection with the acts or omissions of Bank in
reliance upon any certificate or other paper believed by Bank to be genuine or
with respect to any other thing that Bank may do or refrain from doing, unless
such act or omission amounts to fraud, willful malfeasance, gross negligence or
breach of contract. In connection with the performance of its duties pursuant to
the Loan Documents, Bank may consult with counsel of its own selection, and
anything that Bank may do or refrain from doing, in good faith and in reliance
upon the opinion of such counsel, shall be a complete defense against any claim
of any Person on account thereof. Borrower shall indemnify and hold Bank
harmless from and against all liability disclaimed in this Section.

         Section 11.03. Brokers' Fees. Bank shall not be required to pay any
premium, brokerage fee, commission, finder's fee or other compensation in
connection with the Loan, and Borrower shall indemnify and hold Bank harmless
from and against all loss or expense suffered or incurred by Bank by reason of
any claim for such compensation.

         Section 11.04. Governing Law. This Agreement and all other Loan
Documents shall be construed and enforced in accordance with and governed by the
laws of the State of Tennessee without regard to conflict of law provisions
thereof.

         Section 11.05. Borrower's Payment of Costs and Expenses. Whether or not
all or a portion of the Loan is disbursed, the Borrower shall pay all fees,
charges and expenses incurred in the procuring, making, servicing and collecting
of the Loan including, without limitation, charges for mortgagee title insurance
and the examination of title for the Project, expenses of surveys, mortgage
recording taxes, and fees of the Bank's Architect, fees of attorneys for the
Bank, insurance premiums, taxes, assessments, water rates, sewer rates and other
charges, liens and encumbrances upon the Project and any other similar amounts.
Such amounts, unless sooner paid, shall be paid from time to time as the Bank
shall request either to the Person to whom such payments are due or to the Bank
if the Bank has paid the same, or the Bank may, at its option, deduct from any
Loan advance to be made under this Agreement (or advance to itself for such
purpose) any amount necessary for the payment of such costs, and apply such
amounts in making such payments, and all sums so applied shall be deemed
advances under this Agreement and be evidenced by the Note and secured by the
Deed of Trust. The obligations of the Borrower under this Section shall survive
the termination of this Agreement and the payment and performance in full of the
Obligations.

         Section 11.06. Offset. In addition to, and not in limitation of, all
rights of offset that the Bank or other holder of the Note may have under
applicable law, upon the occurrence of any Event of Default hereunder or any
event which, upon notice or the lapse of time, or both, would become an Event of
Default hereunder, the Bank or other holder of such Note and, to the extent
permitted by applicable law, any participant in the Note or the Loan, shall have
the right to appropriate and apply to the payment of the Note and all other
Obligations any and all balances, credits, deposits, accounts or monies of the
Borrower then or thereafter maintained with the Bank or its affiliates or such
other holder of the Note or Obligations, as applicable.

         Section 11.07. Miscellaneous Conditions. The following conditions shall
be applicable throughout the tern of this Agreement:

                  (a)      No advance of Loan proceeds hereunder shall
constitute a waiver of any of the conditions of Bank's obligation 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 Bank from
thereafter declaring such inability to be an Event of Default as hereinabove
provided.

                  (b)      No work shall be commenced with respect to any
particular segment of construction of the Project until the Plans and
Specifications for such segment shall have been submitted to Bank's Architect
and approved by Bank.

                  (c)      The Bank retains the right to hire at the expense of
the Borrower an independent inspector or firm to review all documents or matters
or make any investigations related to the Project, including any investigation
for Hazardous Materials.

                  (d)      All proceedings taken in connection with the
transactions provided for herein, all surveys, appraisals and documents required
or contemplated by this Agreement or the other Loan Documents and the persons
responsible for the execution and preparation thereof, the General Contractor,
all sureties, all insurers, the form of the Construction Contract, and all
leases, bonds, guaranties and policies of insurance shall be satisfactory to
Bank, and Bank's counsel shall have received copies (or certified copies where
appropriate in such counsel's judgment) of all documents which they may request
in connection therewith.

                  (e)      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 Bank shall, at all times, be free independently to
establish to its satisfaction and in its absolute discretion such existence or
nonexistence.

                  (f)      No materials, Equipment or Fixtures, incorporated by
the Borrower in the construction of the Improvements, shall be purchased or
installed under any security agreement, conditional sales contract, or other
arrangement whereby the seller reserves or purports to reserve title to or any
security interest in such items, or the right to remove or repossess such items,
or consider them personal property after their incorporation in the
Improvements, unless expressly authorized by the Bank in writing.

                  (g)      The Borrower shall at all times keep the Bank fully
informed in writing of the cause of any substantial delay in the progress of
construction of the Improvements.

         Section 11.08. Notices. All written notices hereunder to either party
hereto shall be by certified or registered mail, postage prepaid, or delivered
in person or by telefax, addressed to the party for whom intended at the address

by giving notice hereunder, including the

                                       33

on the date of receipt as shown on the return receipt or as shown by telefax
confirmation, as applicable, and any notice given by personal delivery to an
officer of a party shall be deemed given on the date of receipt as evidenced by
such officer's signed receipt; provided, however, that if any party shall refuse
to accept delivery of any notice so sent, such notice shall be deemed given when
tendered for delivery. Such notices shall be addressed,
