Terms of the Loan Documents. The Mortgagor covenants that it will

          ---------------
visions with respect to the Expense Account.

          6.02.1 Upon written request of the Mortgagee, the Mortgagor 
will pay to the Mortgagee monthly installments, each of which shall be 
equal to one-twelfth (1/12th) of the sum of (a) the estimated annual 
premiums for all insurance policies required by Sections 8.01 and 8.02, 
and (b) the estimated annual Taxes pertaining to the Property, to be 
held by the Mortgagee in the Expense Account and disbursed by the Mort-
gagee to pay insurance premiums as they become due, and the Taxes 
before any penalty or interest shall accrue thereon.  Estimates are 
to be made solely by the Mortgagee and payments shall be made on the 
day of the month designated by the Mortgagee.  No interest shall be 
payable by the Mortgagee on the Expense Account unless, and then only 
to the extent that, applicable law shall otherwise require.  All over-
payments to the Expense Account shall be applied to reduce future 
payments to the Expense Account, if any, or shall be returned to the 
Mortgagor, at the sole discretion of the Mortgagee.

          6.02.2 Upon the request of the Mortgagee, the Mortgagor shall 
pay such additional sums into the Expense Account as the Mortgagee 
determines are necessary, so that one month prior to the date the 
Mortgagee is required to make payments of insurance premiums, or Taxes,
as the case may be, payments can be made therefor out of the Expense 
Account.

          6.02.3 The Mortgagor hereby grants the Mortgagee a security 
interest in the sums on deposit in the Expense Account to secure the 
obligations secured hereby, and upon the occurrence of an Event of 
Default, the Mortgagee may, unless prohibited by applicable law, apply

ditions of the Mortgagor, (b) the ability to use buildings and other

     6.04 Notice With Respect to Ownership and Control of Mortgagor. 
          ---------------------------------------------------------
Mortgagor will at all times promptly notify Mortgagee of all changes 
in the ownership of the stock of Mortgagor. At any time Mortgagee may 
request, Mortgagor shall furnish a complete statement, certified by an
officer of Mortgagor, setting forth all of the stockholders, officers,
and directors of Mortgagor, and the extent of their respective stock 
ownership or control.  In the event the Mortgagor is aware of any other
person or entity having a beneficial interest in such stock, the state-
ment shall also set forth the name of such person or entity and the 
extent of such person's interest.

     6.05 Statement of Amount Owing. Within ten (10) days after re-
          -------------------------
quest from the Mortgagee, the Mortgagor shall certify, in writing, 
the amount of principal and interest then owing on the Loan.

     6.06 Changes in Applicable Tax Laws. In the event (a) any law is 
          ------------------------------
hereafter enacted which imposes a tax upon the Loan, any of the Loan 
Documents, or the transactions evidenced or contemplated by any of the 
Loan Documents, or (b) any law now in force governing the taxation of 
deeds of trust, debts secured by mortgages, or the manner of collecting
any such tax shall be changed or modified, in any manner, so as to 
impose a tax upon the Loan, any of the Loan Documents, or the trans-
actions evidenced or contemplated by any of the Loan Documents, 
(including, without limitation, a requirement that revenue stamps be 
affixed to any or all of the Loan Documents), the Mortgagor will 
promptly pay any such tax.  If the Mortgagor fails to make prompt 
payment, or if any law either prohibits the Mortgagor from making the 
payment or would penalize the Mortgagee if Mortgagor makes the payments,
then the failure, prohibition, or penalty, shall entitle the Mortgagee 
to declare the entire unpaid principal balance of the Loan, together 
with all accrued interest and any other amounts due, immediately due 
and payable, provided that no Event of Default has occurred, and the 
Mortgagor shall thereupon have thirty (30) days to pay the entire 
amount due without penalty. If an Event of Default has occurred or if 
the Mortgagor fails to make payment in full within thirty (30) days, 
then the Mortgagee shall be entitled to exercise all rights hereunder 
as though an Event of Default had occurred.

     6.07 Further Assurances and Continuation Statements. The Mort-
          ----------------------------------------------
gagor from time to time will execute, acknowledge, deliver and record,
at the Mortgagor's sole cost and expense, all further instruments,

statements, transfers, and assurances as in the opinion of the 
Mortgagee's counsel may be

  7

necessary (a) to preserve, continue, and protect the interest of the 
Mortgagee in the Property, (b) to perfect the grant to the Mortgagee 
of every part of the Property, (c) to facilitate the execution of the 
terms of this Mortgage, (d) to secure the rights and remedies of the 
Mortgagee under this Mortgage and the other Loan Documents, or (e) to 
transfer to any new mortgagee or purchaser at a sale hereunder the 
Property, funds, and powers now or hereafter held by Mortgagee here-
under.  The Mortgagor, at the request of the Mortgagee, shall promptly 
execute any continuation statements required by the Uniform Commercial 
Code to maintain the lien on any portion of the Property subject to the
Uniform Commercial Code.

     6.08 Expenses. The Mortgagor shall reimburse the Mortgagee for any 
          --------
sums, including attorney's fees and expenses, incurred or expended by it
(a) in connection with any action or proceeding to sustain the lien, 
security interest, priority, or validity of any Loan Document, (b) to 
protect, enforce, interpret, or construe any of its rights under the 
Loan Documents, (c) for any title examination or title insurance policy
relating to the title to the Property, or (d) for any other purpose 
contemplated by the Loan Documents.  The Mortgagor shall, upon demand, 
pay all such sums together with interest thereon at the Default Interest
Rate defined in the Note accruing from the time the expense is paid.  
All such sums so expended by the Mortgagee shall be secured by this 
Mortgage.  In any action or proceeding to foreclose this Mortgage or 
to recover or collect the Loan, the provisions of law allowing the 
recovery of costs, disbursements, and allowances shall be in addition 
to the rights given by this Section 6.08.

     6.09 Environmental Requirements. The Mortgagor hereby covenants 
          --------------------------
and agrees that, if at any time it is determined that there are 
materials (hereinafter, Environmental Materials") located on the 
Property which under any Environmental Requirements require special 
handling in collection, storage, treatment, disposal or removal, the 
Mortgagor shall, within thirty (30) days after written notice thereof, 
take or cause to be taken, at its sole expense, such actions as may be 
necessary to comply with all Environmental Requirements.  If the Mort-
gagor shall fail to take such action, the Mortgagee may make advances 
or payments towards performance or satisfaction of the same but shall 
be under no obligation to do so; and all sums so advanced or paid, 
including all sums advanced or paid in connection with any judicial or 
administrative investigation or proceeding relating thereto, including, 
without limitation, reasonable attorneys' fees, fines, or other penalty 
payments, shall be at once repayable by Mortgagor and shall bear 
interest at the Default Interest Rate defined in the Note or at the

  8

maximum interest rate which the Mortgagor may by law pay, which ever 
is lower, from the date the same shall become due and payable until 
the date paid, and all sums so advanced or paid, with interest as 
aforesaid, shall become a part of the indebtedness secured hereby.  
Failure of the Mortgagor to comply with all Environmental Requirements
shall constitute and be a default under this Mortgage.  Mortgagor shall
defend, indemnify and hold harmless the Mortgagee against any loss, 
cost or expense incurred by the Mortgagee resulting from the presence 
on the Property at any time of any Environmental Materials.

          ---------------------------------------------

Mortgagor shall not permit the Property, or any part or portion thereof
or any interest therein, to be transferred (whether by voluntary or 
involuntary conveyance, merger, operation of law, or otherwise) without
the prior written consent of the Mortgagee.  Any transferee of the 
Property or any part or portion thereof or any interest therein, by 
virtue of its acceptance of the transfer, shall (without in any way 
affecting Mortgagor's liability under the Loan Documents) be conclu-
sively deemed to have agreed to assume primary personal liability for 
the performance of the Mortgagor's obligations under the Loan Documents.
This section shall not apply to any condemnation, any disposition per-
mitted by Section 7.12, any Lease entered into in compliance with

of the Property, except supplies consumed or raw materials, work in 
progress and finished goods sold or transferred in the ordinary course 
of business and operations as they are currently conducted, shall be 
removed from the Land, demolished, or materially altered without the 
prior written consent of the Mortgagee.  The Mortgagor may, without 
consent and free from the lien and security interest of this Mortgage, 
remove and dispose of any worn out or obsolete fixtures or equipment 
which are a part of the Property, provided that prior to or simul-
taneously with their removal, such fixtures and equipment shall be
 replaced with fixtures or equipment of equal or greater value.  The 
replacement fixtures or equipment shall be free of all Encumbrances, 
shall automatically be subject to the lien and security interest of 
this Mortgage, and shall automatically be subject to the granting 
clauses hereof.  Upon the sale of any removed fixtures and equipment 
which are not replaced, the proceeds shall, at the election of the 
Mortgagee, be applied as a prepayment of the Loan, to be applied in 
inverse order of maturity.  All sales shall be conducted in a commer-
cially reasonable manner.

     7.13 Taxes and Permitted Contests. The Mortgagor shall pay: (a) 
          ----------------------------
all Taxes on or before the date any interest or penalty begins to accrue

become a lien or charge upon the Property to such an extent as to 
materially and adversely affect the Mortgagor's ability to use the 
Property for the purposes for which it was designed or intended; 
provided however, that the Mortgagor shall not be required to pay any 
Taxes or claim the amount, validity or payment of which is being con-
tested, in good faith, by appropriate legal proceedings, and so long 
as, in the sole opinion of the Mortgagee, no part of the Property is 
in danger of being sold, forfeited or lost and the contest is not 
impairing the security for the Loan.  Upon payment thereof, the Mort-
gagor shall promptly supply the Mortgagee with receipts showing the 
payment of the Taxes or claim.

     SECTION 8. INSURANCE AND CONDEMNATION

     8.01 Casualty and Liability Insurance. The Mortgagor shall at 
          --------------------------------
all times keep the Property insured for the benefit of the Mortgagor 
and the Mortgagee against loss or damage by fire by fire insurance 
and extended coverage insurance and against such other hazards, 
casualties, and contingencies, all as Mortgagee may require from time 
to time.  Such insurance shall be written in amounts equal to one 
hundred percent (100%) of the replacement value of the Property or 
such other amount as may be approved by Mortgagee.  Such insurance 
shall be written in forms and by companies satisfactory to the Mort-
gagee, and the losses thereunder shall be payable to the Mortgagee 
alone and not to the Mortgagor and the Mortgagee, jointly.  The 
policy or policies of such casualty insurance shall, if requested by 
Mortgagee, be delivered to and retained by the Mortgagee, and the 
Mortgagor shall provide the Mortgagee with receipt evidencing the 
payment of all premiums due on such policies.  The Mortgagor shall 
give the Mortgagee prompt notice of any loss covered by such casualty 
insurance, and the Mortgagee shall have the right (subject to the 
approval of Mortgagor, so long as no Event of Default has occurred) 
to adjust any loss covered by an insurance policy.  All monies 
received as payment for a loss covered by an insurance policy 
("Insurance Proceeds") shall be paid over to the Mortgagee to be 
applied, at the option of the Mortgagee, either to the prepayment of 
the indebtedness secured by the Mortgage or to the payment of other 
charges or expenses actually incurred by the Mortgagor in the res-
toration, reconstruction, repair, renovation' or replacement of the 
Property; provided, however, that the application of Insurance 
Proceeds shall be made at the option of the Mortgagor so long as no 
default or Event of Default has occurred and so long as the Insurance 
Proceeds are sufficient, together with other funds deposited for this 
purpose with the Mortgagee by Mortgagor, to restore the Property to a 
condition and value satisfactory to the Mortgagee.

     The Mortgagor may not take out separate insurance concurrent in 
form or contributing in the event of loss with that required to be 
maintained under the above paragraph unless

  13

the mortgagee is included thereon as a named insured with losses 
payable to the Mortgagee as above provided.  The Mortgagor shall 
immediately notify the Mortgagee whenever any such separate insurance 
is taken out and shall promptly deliver to the Mortgagee the policy 
or policies of such insurance.

     If any of the Property is located in an area which has been iden-
tified as a flood hazard area, the Mortgagor will keep the Property 
covered by flood insurance in an amount at least equal to the full 
amount secured by this Mortgage or the maximum limit 6f coverage 
available for the Property.

     Unless a written waiver from Mortgagee is obtained, Mortgagor 
shall (a) keep all of its insurable properties insured against all risks
usually insured against by persons operating like properties in the 
localities where the properties are located; (b) maintain public lia-
bility insurance against claims for personal injury, death or property
damage suffered by others upon or in or about any premises occupied by
it or occurring as a result of its maintenance or operation of any 
automobiles, trucks or other vehicles or airplanes or other facilities 
or as a result of the use of products sold by it or services rendered 
by it; and (c) maintain all such worker's compensation or similar 
insurance as may be required under the laws of any state or jurisdic-
tion in which it may be engaged in business.

     8.02 Business Interruption Insurance. If requested by Mortgagee, 
          -------------------------------
the Mortgagor shall also carry and maintain business interruption 
insurance on the Property in an amount equal to six (6) months pro-
jected income, as approved by Mortgagee.

     8.03 Condemnation and Allocation of Condemnation Awards. Mortgagor, 
          --------------------------------------------------
immediately upon obtaining knowledge of the institution of any proceeding
for a condemnation, will notify the Mortgagee of such proceedings.  The 
Mortgagee may participate in any such proceedings, and Mortgagor will, 
from time to time, deliver to them all instruments requested by it to 
permit such participation.  Any award or payment made as a result of 
any Taking shall be paid to the Mortgagee, to be applied (a) if funds 
sufficient to restore the remainder of the Property are available from 
such award or payment (together with other funds supplied or caused to 
be supplied by Mortgagor) and no Event of Default is then outstanding, 
to the restoration of the remainder of the Property, or (b) if suffi-
cient funds are not available to restore the remainder of the 
Property, or an Event of Default is then outstanding, to prepayment 
of amounts due under the Note in inverse order of maturity.  All 
moneys not utilized for the repair or restoration of the remainder 
of the Property shall be applied

  14



as a prepayment of amount due under the Note, in inverse order of matur
ity. The application of any award or payment as a prepayment of amounts
due under the Note shall take effect only on the actual date of the 
receipt of the payment or award by the Mortgagee. In the event any 
payment or award is used to restore the Property, as aforesaid, the 
Mortgagee shall not be obligated to see to the proper allocation 
thereof nor shall any amount so used be deemed a payment of any indebt-
edness secured by this Mortgage.  Payments or awards to be used for 
restoration purposes, as aforesaid, shall be held by the Mortgagee and 
disbursed under such terms and conditions, to such persons, and at such
times, as Mortgagee may determine.
