THIS LEASE AGREEMENT is made and entered into as of the date set forth below 
between Faison & Associates, Inc. d/b/a Southland Management Company, not

                                                              ---------------
registered fictitious name), hereinafter referred to as "Lessor" and NOVELLUS
                                                                     --------

--------------
                                 W I T N E S S E T H:

     1.  LEASED PREMISES:  In consideration of the rents, terms, provisions and
covenants of this Lease, Lessor hereby leases, lets and demises to Lessee the
following described premises (referred to as "leased premises" and containing
approximately 1,720 square feet) situated at PLAZA CENTRAL I, (sometimes 
                                             ---------------
referred to as "the building" or "the project"):
                                             6220 S. Orange Blossom Trail
                                             Suite 186
                                             Orlando, Florida 32809
                                             (See Exhibit "A" (floor plan)    
                                              attached hereto and made a part 
                                             hereof.)


     2.  TERM:  Subject to and upon the conditions set forth below, the term of
this Lease shall commence on (FEBRUARY 1, 1996, the "commencement date"), and
                             ------------------
shall terminate THIRTY-SIX (36) months thereafter.
                ---------------

     3.  RENT:  (a) Lessee agrees to pay monthly as base rental during the term
of this Lease the sum of ONE THOUSAND SEVEN HUNDRED TWENTY & 00/100 DOLLARS
                         ---------------------------------------------------
($1,720.00), which amount shall be payable to Lessor at the address shown below
-----------
on the first day of the month.  One monthly installment of rent shall be due and
payable on the date of execution of this Lease by Lessee for the first month's
rent and a like monthly installment shall be due and payable on or before the
first day of each calendar month succeeding the "commencement date" during the
demised term; provided, that if the "commencement date" should be a date other
than the first day of a calendar month, the monthly rental set forth above shall
be prorated to the end of that calendar month, and all succeeding installments
of rent shall be payable on or before the first day of each succeeding calendar
month during the demised term.  Lessee shall pay, as additional rental, all
other sums due under this Lease.

          (b)  On the date of execution of this Lease by Lessee, there shall be
due and payable by Lessee a security deposit in an amount equal to one monthly
rental installment to be held for the performance by Lessee of Lessee's
covenants and obligations under this lease, it being expressly understood that
the deposit shall not be considered an advance payment of rental or a measure of
Lessor's damage in case of default by Lessee.  Upon the occurrence of any event
of default by Lessee or breach by Lessee of Lessee's covenants under this Lease,
Lessor may, from time to time, without prejudice to any other remedy, use the
security deposit to the extent necessary to make good any arrears of rent and/or
any damage, injury, expense or liability caused to Lessor by the event of
default or breach of covenant, any remaining balance of the security deposit to
be returned by Lessor to Lessee upon termination of this Lease.

          (c)  If any increase in the fire insurance premiums paid by Lessor 
for the building in which Lessee occupies space is caused by Lessee's use and 
occupancy of the leased premises, or if Lessee vacates the leased premises 
and causes an increase in such premiums, then Lessee shall pay as additional 
rental the amount of such increase to Lessor.

          (d)  Other remedies for nonpayment of rent notwithstanding, if the
monthly rental payment is not received by Lessor on or before the tenth day of
the month for which rent is due, or if any other payment due Lessor by Lessee is
not received by Lessor on or before the tenth day of the month next following
the month in which Lessee was invoiced, a service charge of five per cent (5%)
of such past due amount shall become due and payable in addition to such amounts
owed under this Lease.

                                                                    See Addendum

     4.  SIGNS:  (a)  If the leased premises are within a multi-story 
building, Lessor will furnish and install a suitable building directory and 
establish suite numbers to facilitate locating and identifying Lessee's 
premises.  In order to effect uniformity, to control the graphics, and to 
maintain dignified aesthetics, Lessor will also furnish and install at the 
entrance door to Lessee's premises a uniform suite number plate and a name 
plate.  Signs, name plates or graphics which are wholly within the leased 
premises and not visible from the exterior of the building or from public 
spaces within the building will be permitted.

          (b)  If the leased premises are within a single-story building which
has integral exterior sign pylons or sign plaques, Lessee shall have the right
to install letters upon a sign plaque provided by Lessor or upon the sign pylon
adjacent to the leased premises, if space is available.  The letters, numerals,
emblems, trademarks, insignia and other designs shall be of non-illuminated
plastic, porcelain enamel or aluminum and shall be individual cut-out letters
using the surface of the pylon or sign plaque as background and shall be subject
to approval of Lessor for the purpose of maintaining architectural continuity
and quality of design.  If Lessee has not installed a sign in accordance with
the provisions of this paragraph within ninety (90) days following the
commencement date of this Lease, Lessee's right to install a sign shall
terminate.

          (c)  If the leased premises are within a single story building with or
without integral exterior sign pylons, Lessee shall have the right to place
lettering upon the entrance doors, plate glass windows or sign plaques of the
leased premises; provided, however, that the lettering shall not exceed six
inches in height and shall be subject to the approval of Lessor.  If the leased
premises open off of a public corridor or lobby, Lessor will furnish and install
a uniform number plate and name plate for Lessee for installation at the
corridor door, and Lessor will furnish and install a suitable building directory
to facilitate locating and identifying Lessee's premises.

          (d)  Lessee agrees that no other sign (mobile or stationary) of any
description shall be erected, placed or painted in or about the leased premises.
Lessee shall, at Lessee's expense, remove all signs at the termination of this
Lease, and the installation and removal shall be in such manner as to avoid
injury, defacement or overloading of the building or other improvements.

     5.  USAGE AND INSURANCE:  Lessee warrants and represents to Lessor that the
leased premises shall be used and occupied only for the purpose of general
office use.  Lessee shall occupy the leased premises, conduct its business and
control its agents, employees, invitees and visitors in such a manner as is
lawful, reputable and will not create any nuisance or otherwise interfere with,
annoy or disturb any other tenant in its normal business operations or Lessor in
its management of the building.  Lessee shall not commit, or suffer to be
committed, any waste on the leased premises, nor shall Lessee permit the leased
premises to be used in any way which would, in the opinion of the Lessor, be
extra hazardous on account of fire or otherwise which would in any way increase
or render void the fire insurance on the leased premises or contents of the
building.

     6.  JANITORIAL SERVICE:  Lessor shall furnish janitorial services during
the term of this Lease.  The janitorial services shall be provided five times
per week during the term of this Lease.

     7.  BUILDING SERVICES:  (a)  Lessor shall furnish gas, water and
electricity for Lessee during the term of this Lease.  Lessee shall pay all
telephone charges.  Lessor shall furnish Lessee hot and cold water at those
points of supply provided for general use of other tenants in the building,
central heating and air conditioning in season (at times Lessor normally
furnishes these services to other tenants in the building, and at temperatures
and in amounts as are considered by Lessor to be standard or in compliance with
any governmental regulations, such service on Saturday afternoons, Sundays and
holidays to be furnished only upon the request of Lessee, who shall bear the
entire cost).  Lessor shall also furnish routine maintenance, painting and
electrical lighting service for all public areas and special service areas of
the building in the manner and to the extent deemed by Lessor to be standard. 
Lessor shall not bear the utility costs (including meter installation and air
conditioning costs) occasioned by electrodata processing machines, computers and
similar machines of high electrical consumption.  Failure by Lessor to any
extent to furnish these defined services, or any cessation thereof, resulting
from causes beyond the control of Lessor shall neither render Lessor liable in
any respect for damages to either person or property, be construed as an
eviction of Lessee, work an abatement of rent nor relieve Lessee from
fulfillment of any covenant in this Lease.  Should any of the equipment or
machinery break down, or for any cause cease to function properly, Lessor shall
use reasonable diligence to repair the same promptly, but Lessee shall have no
claim for rebate on account of any interruption in service occasioned from the
repairs.

          (b)  Lessor shall furnish and install window coverings on all exterior
windows to maintain a uniform exterior appearance.  Lessee shall not remove or
replace these window coverings or install any other window covering which would
affect the exterior appearance of the building.  Lessee may install lined or
unlined over draperies on the interior sides of the Lessor furnished draperies,
for interior appearance, or to reduce light transmission, provided such over
draperies do not affect the exterior appearance of the building.

                                         -2-

     8.  RELOCATION:  In the event Lessor determines to utilize the leased
premises for other purposes during the term of this Lease, Lessee agrees to
relocate to other space in the building and/or project designated by Lessor,
provided such other space is of equal or larger size than the leased premises
and has at least the same number of windows.  Lessor shall pay all out-
of-pocket expenses of any such relocation, including the expenses of moving and
reconstruction of all Lessee furnished and Lessor furnished improvements.  In
the event of such relocation, this Lease shall continue in full force and effect
without any change in the terms and other conditions, but with the new location
substituted for the old location set forth in paragraph 1 of this Lease.

     9.  REPAIRS AND MAINTENANCE:  (a)  Unless otherwise expressly provided,
Lessor shall not be required to make any improvements, replacements or repairs
of any kind or character to the leased premises during the term of this Lease,
except repairs to walls, doors, corridors, windows and other structures and
equipment within and serving the leased premises, and additional maintenance as
may be necessary because of damage by persons other than Lessee, its agents,
employees, invitees, licensees or visitors, and as may be necessary solely
because of the negligence of Lessor, which repairs shall be made by Lessor at
its expense beginning not more than fifteen (15) days after written notice by
Lessee.  Lessor's cost of maintaining the items set forth in this subparagraph
are subject to the additional rental provisions in paragraph 3.  Lessor shall
not be liable to Lessee, except as expressly provided in this Lease, for any
damage or inconvenience, and Lessee shall not be entitled to any abatement or
reduction of rent by reason of any repairs, alterations or additions made by
Lessor under this Lease.

          (b)  Lessee shall, at its own cost and expense, repair or replace any
damage or injury to all or any part of the leased premises caused by Lessee or
Lessee's agents, employees, invitees, licensees or visitors; provided, however,
if Lessee fails to make the repairs or replacements promptly, Lessor may, at its
option, make the repairs or replacements and the costs of such repairs or
replacements shall be charged to Lessee as additional rental and shall become
payable by Lessee with the payment of the rental next due hereunder.

          (c)  Lessee shall not allow any damage to be committed on any portion
of the leased premises, and at the termination of this Lease, by lapse of time
or otherwise, Lessee shall deliver the leased premises to Lessor in as good
condition as existed at the commencement date or completion date of this Lease,
ordinary wear and tear excepted.  The cost and expense of any repairs necessary
to restore the condition of the leased premises shall be borne by Lessee, and if
Lessor undertakes to restore the leased premises it shall have a right of
reimbursement against Lessee.

          (d)  All requests for repairs or maintenance that are the
responsibility of Lessor pursuant to any provision of this Lease must be made in
writing to Lessor at the address set forth below.

     10.  COMPLIANCE WITH LAWS, RULES AND REGULATIONS:  Lessee, at Lessee's
expense, shall comply with all laws, ordinances, orders, rules and regulations
of state, federal, municipal or other agencies or bodies having jurisdiction
relating to the use, condition and occupancy of the leased premises.  Lessee
will comply with the rules of the building adopted by Lessor which are set forth
on a schedule attached to this Lease.  Lessor shall have the right at all times
to change the rules and regulations of the building or to amend them in any
reasonable manner as may be deemed advisable for the safety, care and
cleanliness, and for the preservation of good order, of the leased premises. 
All changes and amendments in the rules and regulations of the building will be
sent by Lessor to Lessee in writing and shall thereafter be carried out and
observed by Lessee.

     11.  LESSOR IMPROVEMENTS:  If construction to the leased premises is to be
performed by Lessor prior to Lessee's occupancy, Lessor will, at its expense,
commence and/or complete the construction of the improvements constituting the
leased premises, including partitions, in accordance with the floor plan and its
specifications agreed to by the parties and made a part of this Lease by
reference.  The plans and specifications shall be approved and signed by the
parties prior to the commencement of construction.  Any changes or modifications
to the approved plans and specifications shall be made and accepted by written
change order signed by Lessor and Lessee and shall constitute an amendment to
this Lease.  Upon completion of the building and other improvements in
accordance with the plans and specifications, Lessee agrees to execute and
deliver to Lessor a letter accepting delivery of the leased premises.

     12.  ALTERATIONS AND IMPROVEMENTS:  Lessee shall not make or allow to be
made any alterations or physical additions in or to the leased premises without
first obtaining the written consent of Lessor.  Any alterations, physical
additions or improvements to the leased premises made by Lessee shall at once
become the property of Lessor and shall be surrendered to Lessor upon the
termination of this Lease.  Lessor, at its option, may require Lessee to remove
any physical additions and/or repair any alterations in order to restore the
leased premises to the condition existing at the time Lessee took possession,
all costs of removal and/or alterations to be borne by Lessee.  This clause
shall not apply to moveable equipment or furniture owned by Lessee which may be
removed by Lessee at the end of the term of this Lease if Lessee is not then in
default and if such equipment and furniture is not then subject to any other
rights, liens and interests of Lessor.

     13.  CONDEMNATION:  (a)  If, during the term (or any extension or renewal)
of this Lease, all or a substantial part of the leased premises are taken for
any public or quasi-public use under any governmental law, ordinance or
regulation, or by right of eminent domain or by purchase in lieu thereof, and
the taking would prevent or materially interfere with the use of the leased
premises for the purpose for which they are then being used, this Lease shall
terminate and the rent shall be abated during the unexpired portion of this
Lease effective on the date physical possession is taken by the condemning
authority.  Lessee shall have no claim to the condemnation award.

          (b)  In the event a portion of the leased premises shall be taken for
any public or quasi-public use under any governmental law, ordinance or
regulation, or by right of eminent domain or by purchase in lieu thereof, and
this Lease is not terminated as provided in subparagraph (a) above, Lessor may,
at Lessor's sole risk and expense, restore and reconstruct the building and
other improvements on the leased premises to the extent necessary to make it
reasonably tenable.  The rent payable under this Lease during the unexpired
portion of the term shall be adjusted to such an extent as may be fair and
reasonable under the circumstances.  Lessee shall have no claim to the
condemnation award.

     14.  FIRE AND CASUALTY:  (a)  If the leased premises should be totally
destroyed by fire or other casualty, or if the leased premises should be so
damaged so that rebuilding cannot reasonably be completed within ninety (90)
working days after the date of written notification by Lessee to Lessor of the
destruction, this Lease shall terminate and the rent shall be abated for the
unexpired portion of the Lease, effective as of the date of the written
notification.

          (b)  If the leased premises should be partially damaged by fire or
other casualty, and rebuilding or repairs can reasonably be completed within
ninety (90) working days from the date of written notification by Lessee to
Lessor of the destruction, this Lease shall not terminate, but Lessor may at its
sole risk and expense proceed with reasonable diligence to rebuild or repair the
building or other improvements to substantially the same condition in which they
existed prior to the damage.  If the leased premises are to be rebuilt or
repaired and are untenantable in whole or in part following the damage, and the
damage or destruction was not caused or contributed to by act or negligence of
Lessee, its agents, employees, invitees or those for whom Lessee is responsible,
the rent payable under this Lease during the period for which the leased
premises are untenantable shall be adjusted to such an extent as may be fair and
reasonable under the circumstances.  In the event that Lessor fails to complete
the necessary repairs or rebuilding within ninety (90) working days from the
date of written notification by Lessee to Lessor of the destruction, Lessee may
at its option terminate this Lease by delivering written notice of termination
to Lessor, whereupon all rights and obligations under this Lease shall cease to
exist.

     15.  PROPERTY INSURANCE:  Lessor shall at all times during the term of this
Lease maintain a policy or policies of insurance with the premiums paid in
advance, issued by and binding upon some solvent insurance company, insuring the
building against all risk of direct physical loss in an amount equal to ninety
percent (90%) of the full replacement cost of the building structure and its
improvements as of the date of the loss; provided, that Lessor shall not be
obligated in any way or manner to insure any personal property (including, but
not limited to, any furniture, machinery, goods or supplies) of Lessee or which
Lessee may have upon or within the leased premises or any fixtures installed by
or paid for by Lessee upon or within the leased premises or any additional
improvements which Lessee may construct on the leased premises.  Lessee shall
provide to Lessor a Certificate of Insurance as proof of coverage.

                                         -3-

     16.  WAIVER OF SUBROGATION:  Anything in this Lease to the contrary
notwithstanding, Lessor and Lessee hereby waive and release each other of and
from any and all rights of recovery, claim, action or cause of action, against
each other, their agents, officers and employees, for any loss or damage that
may occur to the leased premises, improvements to the building of which the
leased premises are a part, or personal property (building contents) within the
building, by reason of fire or the elements regardless of cause or origin,
including negligence of Lessor or Lessee and their agents, officers and
employees.  Because this paragraph will preclude the assignment of any claim
mentioned in it by way of subrogation or otherwise to an insurance company or
any other person, each party to this Lease agrees immediately to give to each
insurance company which has issued to it policies of insurance covering all risk
of direct physical loss, written notice of the terms of the mutual waivers
contained in this paragraph, and to have the insurance policies properly
endorsed, if necessary, to prevent the invalidation of the insurance coverages
by reason of the mutual waivers contained in this paragraph.

     17.  HOLD HARMLESS:  Lessor shall not be liable to Lessee's employees,
agents, invitees, licensees or visitors, or to any other person, for any injury
to person or damage to property on or about the leased premises caused by the
negligence or misconduct of Lessee, its agents, servants or employees, or of any
other person entering upon the leased premises under express or implied
invitation by Lessee, or caused by the building and improvements located on the
leased premises becoming out of repair, or caused by leakage of gas, oil, water
or steam or by electricity emanating from the leased premises.  Lessee agrees to
indemnify and hold harmless Lessor of and from any loss, attorney's fees,
expenses or claims arising out of any such damage or injury.

     18.  QUIET ENJOYMENT:  Lessor warrants that it has full right to execute
and to perform this Lease and to grant the estate demised and that Lessee, upon
payment of the required rents and performing the terms, conditions, covenants
and agreements contained in this Lease, shall peaceably and quietly have, hold
and enjoy the leased premises during the full term of this Lease as well as any
extension or renewal thereof.  Lessor shall not be responsible for the acts or
omissions of any other lessee or third party that may interfere with Lessee's
use and enjoyment of the leased premises.

     19.  LESSOR'S RIGHT OF ENTRY:  Lessor shall have the right, at all
reasonable hours, to enter the leased premises for the following reasons:
inspection; cleaning or making repairs; making alterations or additions as
Lessor may deem necessary or desirable; determining Lessee's use of the leased
premises, or determining if an act of default under this Lease has occurred.

     20.  ASSIGNMENT OR SUBLEASE:  Lessor shall have the right to transfer and
assign, in whole or in part, its rights and obligations in the building and
property that are the subject of this Lease.  Lessee shall not assign this Lease
or sublet all or any part of the leased premises without the prior written
consent of Lessor.  Lessor shall have the option, upon receipt from Lessee of
written request for Lessor's consent to subletting or assignment, to cancel this
Lease as of the date the requested subletting or assignment is to be effective. 
The option shall be exercised, if at all, within fifteen (15) days following
Lessor's receipt of such written request by delivery to Lessee of written notice
of Lessor's intention to exercise the option.  In the event of any assignment or
subletting, Lessee shall nevertheless at all times remain fully responsible and
liable for the payment of the rent and for compliance with all of its other
obligations under the terms, provisions and covenants of this Lease.  Upon the
occurrence of an "event of default" as defined below, if all or any part of the
leased premises  are then assigned or sublet, Lessor, in addition to any other
remedies provided by this Lease or provided by law, may, at its option, collect
directly from the assignee or subtenant all rents becoming due to Lessee by
reason of the assignment or sublease, and Lessor shall have a security interest
in all properties on the leased premises to secure payment of such sums.  Any
collection directly by Lessor from the assignee or subtenant shall not be
construed to constitute a novation or a release of Lessee from the further
performance of its obligations under this Lease.

     21.  LANDLORD'S LIEN:  As security for payment of rent, damages and all
other payments required to be made by this Lease, Lessee hereby grants to Lessor
a lien upon all property of Lessee now or subsequently located upon the leased
premises.  If Lessee abandons or vacates any substantial portion of the leased
premises or is in default in the payment of any rentals, damages or other
payments required to be made by this Lease or is in default of any other
provision of this Lease, Lessor may enter upon the leased premises, by picking
or changing locks if necessary, and take possession of all or any part of the
personal property, and may sell all or any part of the personal property at a
public or private sale, in one or successive sales, with or without notice, to
the highest bidder for cash, and, on behalf of Lessee, sell and convey all or
part of the personal property to the highest bidder, delivering to the highest
bidder all of Lessee's title and interest in the personal property sold to him. 
The proceeds of the sale of the personal property shall be applied by Lessor
toward the reasonable costs and expenses of the sale, including attorney's fees,
and then toward the payment of all sums then due by Lessee to Lessor under the
terms of this Lease; any excess remaining shall be paid to Lessee or any other
person entitled thereto by law.

     22.  UNIFORM COMMERCIAL CODE:  This Lease is intended as and constitutes a
security agreement within the meaning of the Uniform Commercial Code of the
state in which the leased premises are situated and, Lessor, in addition to the
rights prescribed in this Lease, shall have all of the rights, titles, liens and
interests in and to Lessee's property now or hereafter located upon the leased
premises which are granted a secured party, as that term is defined, under the
Uniform Commercial Code to secure the payment to Lessor of the various amounts
provided in this Lease.  Lessee will on request execute and deliver to Lessor a
financing statement for the purpose of perfecting Lessor's security interest
under this Lease or Lessor may file this Lease or a copy thereof as a financing
statement.

     23.  DEFAULT BY LESSEE:  The following shall be deemed to be events of
default by Lessee under this Lease:

          (a)  Lessee shall fail to pay when due any installment of rent or any
other payment required persuant to this Lease; and such failure is not cured by
Lessee within 5 days from receipt of written notice;
          (b)  Lessee shall abandon any substantial portion of the leased
premises;
          (c)  Lessee shall fail to comply with any term, provision or covenant
of this Lease, other than the payment of rent, and the failure is not cured
within thirty (30) days after written notice to Lessee;
          (d)  Lessee shall file a petition or be adjudged bankrupt or insolvent
under the National Bankruptcy Act, as amended, or any similar law or statute of
the United States or any state; or a receiver or trustee shall be appointed for
all or substantially all of the assets of Lessee; or Lessee shall make a
transfer in fraud of creditors or shall make an assignment for the benefit of
creditors; or
          (e)  Lessee shall do or permit to be done any act which results in a
lien being filed against the leased premises or the building and/or project of
which the leased premises are a part.

     24.  REMEDIES FOR LESSEE'S DEFAULT:  Upon the occurrence of any event of
default set forth in this Lease, Lessor shall have the option to pursue any one
or more of the following remedies without any notice or demand:

          (a)  Terminate this Lease, in which event Lessee shall immediately 
surrender the leased premises to Lessor, and if Lessee fails to surrender the 
leased premises, Lessor may, without prejudice to any other remedy which it 
may have for possession or arrearages in rent, enter upon and take possession 
of the leased premises, by picking or changing locks if necessary, and lock 
out, expel, or remove Lessee and any other person who may be occupying all or 
any part of the leased premises without being liable for prosecution of any 
claim for damages.  Lessee agrees to pay on demand the amount of all loss and 
damage which Lessor may suffer by reason of the termination of the Lease 
under this subparagraph, whether through inability to relet the leased 
premises on satisfactory terms or otherwise.

          (b)  Enter upon and take possession of the leased premises, by picking
or changing locks if necessary, and lock out, expel or remove Lessee and any
other person who may be occupying all or any part of the leased premises without
being liable for any claim for damages and relet the leased premises on behalf
of Lessee and receive directly the rent by reason of the reletting.  Lessee
agrees to pay Lessor on demand any deficiency that may arise by reason of any
reletting of the leased premises; further, Lessee agrees to reimburse Lessor for
any expenditures made by it for remodeling or repairing in order to relet the
leased premises.

          (c)  Enter upon the leased premises, by picking or changing locks if
necessary, without being liable for prosecution of any claim for damages, and do
whatever Lessee is obligated to do under the terms of this Lease.  Lessee agrees
to reimburse Lessor on

demand for any expenses which Lessor may incur in effecting compliance with
Lessee's obligations under this Lease; further, Lessee agrees that Lessor shall
not be liable for any damages resulting to Lessee from effecting compliance with
Lessee's obligations under this subparagraph caused by the negligence of Lessor
or otherwise.

     25.  WAIVER OF DEFAULT OR REMEDY:  Failure of Lessor to declare an event of
default immediately upon its occurrence, or delay in taking any action in
connection with an event of default, shall not constitute a waiver of the
default, but Lessor shall have the right to declare the default at any time and
take such action as is lawful or authorized under this Lease. Pursuit of any one
or more of the remedies set forth in paragraph 24 above shall not preclude
pursuit of any one or more of the other remedies provided elsewhere in this
Lease or provided by law, nor shall pursuit of any remedy provided constitute
forfeiture or waiver of any rent or damages accruing to Lessor by reason of the
violation of any of the terms, provisions or covenants of this Lease.  Failure
by Lessor to enforce one or more of the remedies provided upon an event of
default shall not be deemed or construed to constitute a waiver of the default
or of any other violation or breach of any of the terms, provisions and
covenants contained in this Lease.

     26.  ACTS OF GOD:  Lessor shall not be required to perform any covenant or
obligation in this Lease, or be liable in damages to Lessee, so long as the
performance or non-performance of the covenant or obligation is delayed, caused
by or prevented by an act of God or force majeure.

     27.  ATTORNEY'S FEES:  In the event Lessee defaults in the performance of
any of the terms, covenants, agreements or conditions contained in this Lease
and Lessor places in the hands of an attorney the enforcement of all or any part
of this Lease, the collection of any rent due or to become due or recovery of
the possession of the leased premises, Lessee agrees to pay Lessor reasonable
attorney's fees for the services of the attorney, whether suit is actually filed
or not.  In no event shall the attorney's fees be less than fifteen percent of
the outstanding balance owed by Lessee to Lessor.

     28.  HOLDING OVER:  In the event of holding over by Lessee after the
expiration or termination of this Lease, the hold over shall be as a tenant at
will and all of the terms and provisions of this Lease shall be applicable
during that period, except that Lessee shall pay Lessor as rental for the period
of such hold over an amount equal to one and one-half the rent which would have
been payable by Lessee had the hold over period been a part of the original term
of this Lease.  Lessee agrees to vacate and deliver the leased premises to
Lessor upon Lessee's receipt of notice from Lessor to vacate.  The rental
payment during the hold over period shall be payable to Lessor on demand.  No
holding over by Lessee, whether with or without consent of Lessor, shall operate
to extend this Lease except as otherwise expressly provided.

     29.  RIGHTS OF FIRST MORTGAGEE:  Lessee accepts this Lease subject and
subordinate to any recorded first mortgage or deed of trust lien presently
existing or hereafter created upon the leased premises.  Lessor is hereby
irrevocably vested with full power and authority to subordinate Lessee's
interest under this Lease to any first mortgage or deed of trust lien hereafter
placed on the leased premises, and Lessee agrees upon demand to execute
additional instruments subordinating this Lease as Lessor may require.  If the
interests of Lessor under this Lease shall be transferred by reason of
foreclosure or other proceedings for enforcement of any first mortgage or deed
of trust on the leased premises, Lessee shall be bound to the transferee
(sometimes called the "Purchaser"), at the option of the Purchaser, under the
terms, covenants and conditions of this Lease for the balance of the term
remaining, and any extentions or renewals, with the same force and effect as if
the Purchaser were Lessor under this Lease, and, if requested by the Purchaser,
Lessee agrees to attorn to the Purchaser, including the first mortgagee under
any such mortgage if it be the Purchaser, as its lessor.

     30.  ESTOPPEL CERTIFICATES:  Lessee agrees to furnish promptly, from time
to time, upon request of Lessor or Lessor's mortgage, a statement certifying, if
applicable, that Lessee is in possession of the leased premises; the leased
premises are acceptable; the Lease is in full force and effect; the Lease is
unmodified; Lessee claims no present charge, lien, or claim of offset against
rent; the rent is paid for the current month, but is not prepaid for more than
one month and will not be prepaid for more than one month in advance; there is
no existing default by reason of some act or omission by Lessor; and such other
matters as may be reasonably required by Lessor or Lessor's mortgagee.

     31.  SUCCESSORS:  This Lease shall be binding upon and inure to the
benefit of Lessor and Lessee and their respective heirs, personal
representatives, successors and assigns.  It is hereby covenanted and agreed
that should Lessor's interest in the leased premises cease to exist for any
reason during the term of this Lease, then notwithstanding the happening of
such event this Lease nevertheless shall remain unimpaired and in full force and
effect and Lessee hereunder agrees to attorn to the then owner of the leased
premises.

     32.  RENT TAX:  If applicable in the jurisdiction where the leased premises
are situated, Lessee shall pay and be liable for all rental, sales and use taxes
or other similar taxes, if any, levied or imposed by any city, state, county or
other governmental body having authority, such payments to be in addition to all
other payments required to be paid to Lessor by Lessee under the terms of this
Lease.  Any such payment shall be paid concurrently with the payment of the rent
upon which the tax is based as set forth above.

     work performed on or about the leased premises or project, including
     installation of telephones, telegraph equipment, electrical devices and

     Lessor.  All such movement shall be under supervision of Lessor and carried
     out in the manner agreed between Lessee and Lessor by prearrangement before
     performance.  Such prearrangement will include determination by Lessor of
     time, method, and routing of movement and limitations imposed by safety 
     or other concerns which may prohibit any article, equipment or any other 
     item from being brought into the building.  Lessee assumes, and shall

reported directly to Lessor.  Your cooperation will be mutually beneficial and
sincerely appreciated.  Lessor reserves the right to make such other and further
reasonable rules and regulations as in its judgment may from time to time be
necessary, for the safety, care and cleanliness of the leased premises, and for
the preservation of good order therein.
