EXHIBIT "A"

GENERAL LEASE PROVISIONS

These following General Lease Provisions shall become effective when
attached to the signed Lease Agreement containing the Specific Lease Provisions
and shall, together with the Exhibits, form the Lease Agreement.

1. ABANDONMENT. Tenant shall not vacate without payment of Rent nor
abandon the Leased Premises at any time during the term of this Lease Agreement,
nor permit the Leased Premises to remain unoccupied for a period longer than
fifteen (15) consecutive days during the term of this Lease Agreement. If Tenant
shall abandon, vacate without payment of Rent, or surrender the Leased Premises,
or be dispossessed by process of law or otherwise, any personal property
belonging to Tenant and left on the Leased Premises shall, at the option of the
Landlord, be deemed abandoned and title thereto shall vest to Landlord. If
Tenant vacates the Leased Premises but continues to pay all sums due hereunder
and otherwise complies with the terms hereof, it shall not be considered
abandonment.

2. ASSIGNMENT OR SUBLEASE. Tenant shall not, either voluntarily or by
operation of law, assign, encumber, pledge, or otherwise transfer or hypothecate
all or any part of Tenant's leasehold estate hereunder, or permit the Leased
Premises to be occupied by anyone other than Tenant or Tenant's employees, or
sublet the Leased Premises or any portion thereof, without Landlord's prior
written consent in every instance, which Landlord shall not unreasonably
withhold, condition or delay. Tenant shall give Landlord written notice of such
desire at least thirty (30) days in advance of the date on which Tenant desires
to make such assignment or sublease, which notice shall include the name,
address, evidence of financial capability, and other pertinent information
regarding the proposed assignee or sublessee.

a. No assignment or subletting by Tenant shall relieve Tenant
of any obligations under this Lease Agreement. Any attempted transfer of this
Lease Agreement by Tenant without the consent of Landlord shall be null and void
and, at the option of Landlord, shall cause termination of this Lease Agreement.
The giving of consent by Landlord in one instance shall not preclude the need
for Tenant, and its successors and assigns, to obtain Landlord's consent to
further transfers.

b. In the event Tenant shall propose to assign or sublet the
Leased Premises and request the consent of Landlord to any assignment or
subletting, or if Tenant shall request consent of Landlord to any other act
Tenant proposes to do, as herein provided, then Tenant shall pay Landlord's
reasonable attorney's fees incurred in connection therewith. Any assignment or

subletting shall not relieve Tenant from responsibility under the Lease
Agreement, and Tenant shall therefore remain liable for the faithful performance
of the Lease Agreement in case of breach or default by assignee or sublessee.

c. If the proposed Base Rental between Tenant and any
Sublessee is greater the Base Rental of this lease, then such excess rental
shall be deemed Additional Rent owed by Tenant to Landlord.

d. Tenant shall not publicly advertise the Rent for which
Tenant is willing to sublet the space; and all public advertisements of the
assignment of the Lease Agreement or sublet of Leased Premises, or any portion
thereof, shall be subject to prior approval in writing by Landlord.

e. In any assignment or transfer, each assignee or transferee,
other than Landlord, shall assume, as provided herein, all obligations of the
Tenant under this Lease Agreement which relate to all or a portion of the Leased
Premises assigned or sublet, as the case may be, and shall be and remain liable
jointly and severally with Tenant for the payment of the Rent and for due
performance of all the terms, covenants, conditions, and agreements herein
contained on Tenant's part to be performed during the term of this Lease
Agreement.

f. No consent by Landlord to any assignment or subletting by
Tenant shall relieve Tenant of any obligation to be performed by the Tenant
under this Lease Agreement, whether accruing before or after such assignment or
subletting, unless granted by Landlord to Tenant in writing. The consent by
Landlord to any assignment or subletting shall not relieve Tenant from the
obligation to obtain Landlord's express written consent to any other assignment
or subletting. Any assignment or subletting which is not in compliance with this
Lease Agreement shall be void, and, at the option of Landlord, shall constitute
a material default by Tenant under this Lease Agreement.

3. ATTORNEY'S FEES. In the event either party places the enforcement of
this Lease Agreement, or any part thereof, or the collection of any rent due, or
to become due hereunder, or recovery of the possession of the Leased Premises in
the hands of an attorney, or files suit upon the same, the nonprevailing (or
defaulting) party shall pay the other party's reasonable attorney's fees and
court costs, in any proceeding, whether at trial, or appeal therefrom, or on any
petition for review, or in bankruptcy.

4. BINDING. Each individual executing this Lease Agreement on behalf of
Tenant and Landlord represents and warrants that he/she is duly authorized to
execute and deliver this Lease Agreement on behalf of Tenant and Landlord, and
that this Lease Agreement is binding upon each in accordance with its terms.

executed by Landlord and Tenant.

Term, reasonable wear and tear, unrepaired casualty that was either not caused
by Tenant or covered by insurance (or that would have been covered by insurance
depicted in Paragraph 25), and condemnation excepted. All property of Tenant
remaining in the Leased Premises after expiration of the Term shall be deemed
conclusively abandoned and may be removed by Landlord, and Tenant shall
reimburse Landlord for the cost of removing the same, subject, however, to
Landlord's right to require Tenant to remove any improvements or additions made
to the Leased Premises by Tenant pursuant to this Lease Agreement, unless
previously agreed to otherwise by the parties in writing,.

b. In doing any work related to the installation of Tenant's
furnishings, fixtures, or equipment in the Leased Premises, Tenant will use only
contractors or workmen consented to by Landlord in writing prior to the time

evidence of workers compensation insurance acceptable lien waivers from such
contractors or workmen. Tenant shall promptly remove any lien or claim of lien
for material or labor claimed against the Leased Premises or Project, or both,
by such contractors or workmen, if such claim should arise, and hereby

damage, expense, or liabilities including, but not limited to, attorney's fees

liens. Landlord hereby consents to Tenant using for the improvements depicted in

destruction, or such longer period as Landlord has estimated, plus such

materials, or any other cause beyond Landlord's reasonable control.

12. EVENTS OF DEFAULT BY TENANT. The following shall constitute events
of default by Tenant: (a) If Tenant shall fail to make any payment due under
this Lease Agreement, and such failure shall continue for ten (10) days after
written notice by Landlord; (b) if a default exists in the performance of any of
the other covenants or conditions which Tenant is required to observe and to
perform, and such default shall continue for thirty (30) days after written
notice by Landlord or such longer period as reasonably required if Tenant
commences and diligently pursues the cure of default within said thirty (30) day
period; (c) if the interest of Tenant under this Lease Agreement is levied upon,
or is under execution or other legal process, or if any petition shall be filed
by or against Tenant to declare Tenant as bankrupt or to delay, reduce, or
modify Tenant's debts or obligations, which petition or case is not dismissed
within sixty days thereafter; (d) if any petition shall be filed or other action
taken to reorganize or modify Tenant's capital structure if Tenant be a
corporation or other entity; (e) if Tenant is declared insolvent, or if any
assignment of Tenant's property is made for the benefit of creditors or if a
receiver or trustee is appointed for Tenant or its property; (f) if Tenant
vacates without payment of rent or abandons the Leased Premises during the term
of this Lease Agreement or any extensions thereof; or (g) if Tenant makes any
transfer of any interest in the Leased Premises not in accordance with the
requirements of this Lease Agreement, then Landlord may treat the occurrence of
any one or more of the foregoing events as a breach of this Lease Agreement and
thereupon, at Landlord's option, Landlord shall have one or more of the
following described remedies in addition to all other rights and remedies
provided at law or in equity:

a. .Landlord may terminate this Lease Agreement and forthwith,
in accordance with applicable law, repossess the Leased Premises and remove all
persons or property therefrom, and be entitled to recover as damages a sum of
money equal to the total of (i) the cost of recovering the Leased Premises (ii)
the unpaid rent owed thereon from due date plus interest thereon at the rate of
18% per annum or the maximum rate permitted by applicable law, whichever is
lower, (iii) the difference between the present value of the balance of the rent
for the remainder of the term, discounted to the present at 8% per annum, minus
the aggregate fair market rental value of the Leased Premises for the remainder
of the Lease Term, and (iv) any other sum of money and damages owed by Tenant to
Landlord;

b. Landlord shall also be entitled to terminate Tenant's right
of possession in accordance with applicable law and to repossess the Leased
Premises, without demand or notice of any kind to Tenant (except as expressly
required herein or by applicable laws), by summary proceedings, any other
applicable action or proceeding, or otherwise, all without terminating this
Lease Agreement, in which event Landlord may, but shall be under no obligation
to, relet the same for the account of Tenant for such rent and upon such terms
as shall be satisfactory to Landlord. None of these actions will be deemed an
acceptance of surrender of the Leased Premises. For the purpose of such
reletting Landlord is authorized to decorate or to make any repairs, changes,
alterations, or additions in or to the Leased Premises that may be necessary or
convenient, and (i) if Landlord shall fail or refuse to relet the Leased
Premises, or (ii) if the same are relet and a sufficient sum shall not be
realized from such reletting, after paying the unpaid Base Rental due hereunder
earned or unpaid at the time of reletting, plus interest thereon at the rate set
forth herein, the cost of recovering possession, and all of the costs and
expenses of such decoration, repairs that are Tenant's obligations hereunder,
changes, alterations, and additions, and the reasonable expense of such
reletting including tenant improvement costs based on a proration of the ratio
of the remaining Lease Term as it compares to the new tenant lease term, and of
the collection of the rent accruing therefrom to satisfy the payment of the rent
provided for in this Lease Agreement, then Tenant shall pay to Landlord as
damages a sum equal to the amount of the rental reserved in this Lease Agreement
for such period or periods, or if the Leased Premises have been relet, Tenant
shall satisfy and pay any such deficiency upon demand therefor from time to
time; and Tenant agrees that Landlord may file suit to recover any sums falling
due under the terms of this Lease Agreement from time to time on one or more
occasions without Landlord being obligated to wait until expiration of the term
of this Lease Agreement and without barfing or affecting in any manner
Landlord's right to bring a later action or actions for further damages; nor
shall such reletting be construed as an election on the part of Landlord to
terminate this Lease Agreement unless a written notice of such intention be
given to Tenant by Landlord. Notwithstanding any such reletting without
termination, Landlord may at any time thereafter elect to terminate this Lease
Agreement for such previous breach.

c. Without prejudice to any other remedy for default, Landlord
may perform any obligation or make any payment required to cure a default by
Tenant. The cost of

performance, including attorneys' fees and all disbursements, shall immediately
be paid by Tenant to Landlord upon demand as Additional Rent.

13. DEFECTS. Tenant agrees to report in writing to Landlord any
defective condition in or about the Leased Premises known to Tenant, and further
agrees to attempt to contact Landlord by telephone immediately in such instance.

14. EMINENT DOMAIN

a. In the event the Leased Premises are taken pursuant to
powers of eminent domain, all awards for the taking other than awards for
interruption of Tenant's business shall belong solely to Landlord, and Tenant
shall make no claim therefor.

b. In the event of a partial taking, which does not result in
a termination of this Lease Agreement, rent shall be abated in proportion to the
part of the Leased Premises so made unusable by said partial taking, and any
award for the taking shall belong solely to Landlord.

c. No temporary taking of the Leased Premises and/or of
Tenant's rights therein or under this Lease Agreement shall terminate this Lease
Agreement or give Tenant any right to any abatement of rent hereunder; and any
award made to Tenant by reason of any such temporary taking shall belong
entirely to Tenant, and Landlord shall not be entitled to share therein. The
Tenant and Landlord will work together to cause the governmental agency
responsible for the taking to restore the Leased Premises and Project, after the
taking, to their original condition prior to the taking.

d. If the whole of the Leased Premises, or so much thereof as
to render the balance unusable by Tenant, shall be taken by any governmental
authority under power of Eminent Domain, this Lease Agreement shall
automatically terminate as of the date of such condemnation, or as of the date
possession is taken by the condemning authority, whichever is earlier. No award
for any partial or entire taking shall be apportioned, and Tenant hereby assigns
to Landlord any award which may be made in such taking or condemnation, together
with any and all rights of Tenant now or hereafter arising in or to the same or
any part thereof, provided, however, that nothing contained herein shall be
deemed to give Landlord any interest in or to require Tenant to assign to
Landlord any award made to Tenant for the taking of personal property,
equipment, and fixtures belonging to Tenant and/or for the interruption of or
damage to Tenant's business or for Tenant's unamortized cost of improvements
installed by Tenant and/or the cost of moving and/or the lost value of Tenant's
unexpired Lease Agreement term.

15. ENTIRE AGREEMENT. This instrument, along with any exhibits and
attachments or other documents affixed hereto or referred to herein, constitute
the entire and exclusive agree-ment between Landlord and Tenant relative to the
Leased Premises herein described, and this

Agreement and said exhibits and attachments and other documents may be altered
and/or revoked only by an instrument in writing signed by both Landlord and
Tenant. Landlord and Tenant hereby agree that all prior written and oral
agreements, understandings and/or practices relative to the leasing of the
Leased Premises are merged in or revoked by this Lease Agreement.

16. ESTOPPEL CERTIFICATE. Tenant shall at any time and from time to
time, upon not less than ten (10) days prior written notice from Landlord,
execute, acknowledge and deliver to Landlord or to other parties as Landlord may
direct, a statement in writing, (a) certifying that this Lease Agreement is
modified and in full force and effect (or, if modified, stating the nature of
such modification and certifying that this Lease Agreement as so modified is in
full force and effect), the date to which the rental and other charges are paid
in advance, and the amount of the Base Rental, Estimated Operating Expense
Adjustment, and the commencement and termination dates of the Lease Agreement,
and (b) acknowledging that there are not, to Tenant's knowledge, any uncured
defaults on the part of Landlord hereunder, or specifying such defaults if any
are claimed. Any such statement may be relied upon by any prospective purchaser
or encumbrancer of all or any portion of the real property of which the Leased
Premises are a part. Tenant's failure to deliver such statement within such time
shall be conclusive upon Tenant that: (i) this Lease Agreement is in full force
and effect, without modification except as may be represented by Landlord, (ii)
there are no uncured defaults in Landlord's performance, and (iii) not more than
one month's Base Rental, or Estimated Operating Expense Adjustment installment,
has been paid in advance. If Landlord desires to finance or refinance the
Project, or any part thereof, Tenant agrees to deliver to any lender designated
by Landlord such financial statements of Tenant as may be reasonably required by
such financial institution. All such financial statements shall be received by
Landlord in confidence and shall be used only for the purpose herein set forth.

17. FORCE MAJEURE. Any prevention, delay, or stoppage of work to be
performed by Landlord or Tenant which is due to strikes, labor disputes,
inability to obtain labor, materials, equipment, or reasonable substitutes
therefor, acts of God, governmental restrictions or regulations or controls,
judicial orders, enemy or hostile government actions, civil commotion, fire or
other casualties, or other causes beyond the reasonable control of the party
obligated to perform hereunder, shall excuse performance of the work by that
party for a period equal to the duration of that prevention, delay, or stoppage.

charges under this Lease Agreement, except as otherwise provided in this Lease
Agreement.

any "Hazardous Substances," as defined below, except in amounts as permitted by
law, to be brought upon or kept or used in or about the Premises or the Project
by Tenant, its agents, employees, contractors, or invitees. Notwithstanding
anything contained in this Lease, Tenant shall in no event be liable with
respect to (i) any Hazardous Substances brought onto or installed on the Leased
Premises prior to the Beginning Date of this Lease Agreement, or (ii) with
respect to the violation of any Hazardous Substance Laws prior to the Beginning
Date of this Lease, or (iii)

Hazardous Substances used, stored, generated or released by anyone other than
Tenant, its agents, invitees or employees, (iv) any violation of any Hazardous
substance laws by anyone other than Tenant, its agents, invitees or employees.

a. Tenant shall at all times and in all respects comply with
all local, state, and federal laws, ordinances, regulations and orders
(collectively, "Hazardous Substances Laws") relating to industrial hygiene,
environmental protection, or the use, analysis, generation, manufacture,

listed pursuant to Section 307 of the Clean Water Act (33 U.S.C. Sections
1317), (vi) defined as a "hazardous waste" pursuant to Section 1004 of the
Resource Conservation and Recovery Act, 42 U.S.C. Sections 6901, ET Seq. (42
U.S.C. Sections 6903) or (vii) defined as "hazardous substance" pursuant to
Section 101 of the Comprehensive Environmental Response, Compensation, and
Liability Act, 42 U.S.C. Sections 9601, ET Seq. (42 U.S.C. Sections 9601).

c. Tenant shall indemnify, defend (by counsel acceptable to
Landlord), protect, and hold harmless Landlord, and each of Landlord's partners,

and against any and all claims, liabilities, penalties, fines, judgments,
forfeitures, losses (including, without limitation), diminution in the value of
the Premises or the Building, damages for the loss or restriction on use of

Premises or the Building, or (b) Tenant's failure to comply with any Hazardous
Substances Law. Tenant's obligations under this Section shall include, without
limitation, and whether foreseeable or unforeseeable, any and all costs incurred
in connection with any investigation of site conditions, and any and all costs
of any required or necessary repair, cleanup, detoxification, or decontamination
of the Premises or the Building, and the preparation and implementation of any
closure, remedial action, or other required plans in

connection therewith. Tenant's obligations under this Section shall survive the
expiration or earlier termination of the term of the Lease. For purposes of the
release and indemnity provisions hereof, any acts or omissions of Tenant, or by
employees, agents, assignees, contractors, or subcontractors of Tenant or others
acting for or on behalf of Tenant (whether or not they are negligent,
intentional, willful, or unlawful), shall be strictly attributable to Tenant.

d. Tenant acknowledges and agrees that it shall not be
unreasonable for Landlord to withhold its consent to any proposed assignment,
subletting, or transfer of Tenant's interest in this Lease if (a) the

property, if the contamination resulted from such Transferee's actions or use of
the property in question; or (c) the proposed Transferee is subject to an
enforcement order issued by any governmental authority in connection with the
use, disposal, or storage of a Hazardous Substance.

e. Landlord does hereby represent to Tenant that, to the best
of Landlord's knowledge, no toxic or hazardous substances have been deposited in
or located on the Leased Premises on the commencement date of the lease except
in the amounts as permitted by law.

any other tenant of the Project or of any other person in or about the Project
for any purpose whatsoever, or due to administrative or criminal action by a
governmental authority, whether such injury, expense, damage, liability, or
claim results either directly or indirectly from the act, omission, negligence,
misconduct, or breach of any provisions of this Lease Agreement by Tenant, the
agents, servants, or employees of Tenant, or any other person entering upon the
Leased Premises under express or implied invitation or consent of Tenant. Tenant
further agrees to reimburse Landlord for any costs or expenses, including, but

for any purpose whatsoever, or due to administrative or criminal action by a
governmental authority, whether such injury, expense, damage, liability, or
claim results either

directly or indirectly from the act, omission, gross negligence, misconduct, or
breach of any provisions of this Lease Agreement by Landlord, the agents,
servants, or employees of Landlord, or any other person entering upon the Leased
Premises under express or implied invitation or consent of Landlord. Landlord
further agrees to reimburse Tenant for any costs or expenses, including, but not

any such holdover period, together with any Additional Rent. No holding over by
Tenant after the termination of this Lease Agreement shall operate to extend the
Lease Agreement term. In the event of any unauthorized holding over, Tenant

against Landlord to whom Landlord may have leased all or any part of the Leased
Premises covered hereby effective upon the termination of this Lease Agreement.

Tenant may terminate it upon not less than thirty (30) days prior written
notice.

21. IMPROVEMENT DELAYS CAUSED BY TENANT. If Tenant shall cause any of
the following delays in the completion of Landlord's Work, then the beginning
date of the Lease Agreement shall be altered: (i) delay caused because Tenant's
requirements for materials or installations are different from Landlord's
"Project Standard Improvements" (the basic improvement package Landlord offers
to tenants of the Project), (ii)delay in the payment of any sum due from Tenant
pertaining to Landlord's Work, (iii) delay in performance or completion by a
party employed by Tenant, (iv) delay by reason of compliance with applicable
laws arising from Tenant's design of Tenant's Improvements, (v) delay by reason
of changes in the work ordered by Tenant or by reason of any Change Order, (vi)
delay by reason of the malfunctioning of any item or aspect of Tenant's
Improvements which was designed by Tenant.

a. In the event of any such delay mentioned above then,
notwithstanding the provisions of the Lease Agreement or any other provision of
Exhibit B, the Beginning Date of the Lease Agreement shall be the earlier of (i)
the date Landlord would have completed Landlord's Work had it not been for
Tenant's delay, or (ii) the earliest Beginning Date as provided in this Lease
Agreement. Any and all cost related to either the illegality or malfunctioning
of any item or aspect of Tenant's Improvements, which arises from Tenant's
design, plans, specifications, or working drawings, shall be borne solely by
Tenant, notwithstanding Landlord's approval or installation of the same.

22. IMPROVEMENTS, ALTERATIONS, AND ADDITIONS. Tenant shall not make or
allow to be made any alterations or physical additions in or to the Leased
Premises which affect the

structure or any other improvements in excess of the amount stated in the
Specific Lease Provisions without first obtaining the written consent of
Landlord. All work shall be done by contractors approved by Landlord. Landlord's
approval or consent shall not be unreasonably withheld or delayed and approval
shall state if the alterations or physical additions shall be removed or
reinstalled by Tenant upon the Expiration Date. Any and all such alterations,
physical additions, or improvements, when made to the Leased Premises by Tenant,
shall at once become the property of Landlord and shall be surrendered to
Landlord upon the termination of this Lease Agreement by lapse of time or
otherwise unless agreed to otherwise in the required Landlord's approval above;
provided, however, this clause shall not apply to movable equipment or furniture
owned by Tenant. Tenant shall comply with all government, local building code
and permitting requirements and provide Landlord with evidence of compliance.
Tenant shall give Landlord written notice five (5) days prior to employing any
laborer or contractor to perform work on the Leased Premises so that Landlord
may post a notice of nonresponsibility if allowed by law. Landlord reserves the
right to require Tenant, at Tenant's expense, to remove such alterations,
physical additions, or improvements upon termination of this Lease Agreement and
to repair any damage caused by such removal. Landlord hereby consents to the
improvements and alterations set forth and/or shown on Exhibit "C" attached

unreasonably interfere with Tenant's use and occupancy.

25. INSURANCE BY LANDLORD. Landlord shall maintain during the term of

to replacement value. Landlord shall not be obligated to insure any furniture,
equipment, machinery, goods, or supplies owned by Tenant or which Tenant may
bring or obtain upon the Leased Premises, or any additional improvements which
Tenant may construct thereon. If the annual premiums charged Landlord for such
insurance exceed the standard premium rates because of the nature of Tenant's
operations, then Tenant shall, upon receipt of appropriate premium invoices,
reimburse Landlord for such increases in premium. Landlord may, should it choose
to do so, self insure all or part of the above referenced risks. Should Landlord
choose to self insure any insurance risks, the cost demonstrated by a bid from a
reputable insurance company shall be included in the cost of insurance for
expense reimbursement purposes.

Leased Premises. Tenant shall comply, at its sole cost, with requirements of the

28. LEASE MEMORANDUM. Neither this Lease Agreement, nor any notice nor
memorandum regarding the terms hereof, shall be recorded by Tenant without the
prior written consent of the Landlord.

or its partners or any of their personal assets for such satisfaction.

any purpose other than as an address of business to be conducted by the Tenant.

venture or similar relationship or arrangement between Landlord and Tenant
hereunder.

32. NOTICES. All notices, demands, consents, and approvals, which may
or are required to be given by either party to the other hereunder, shall be in
writing and shall be deemed to have been fully given when personally delivered
or delivered by a nationally recognized over night courier, or, if the notice is

▇▇▇▇ ▇▇▇▇▇, and ▇▇▇▇▇▇ and ▇▇▇▇▇▇▇▇, ▇▇ ▇. ▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇

date set forth on the receipt, or (iii) three (3) days after the notice is
deposited in the mail.

a. Either party may change its address for notice by at least fifteen
(15) days written notice to the other party. Tenant hereby appoints as its agent
to receive the service of all dispossessory or distraint proceedings and notices
thereunder the person in charge of or occupying the Leased Premises at the time,
and, if no person shall be in charge of or occupying the same, then, if allowed
by law, such service may be made by attaching the same on the main entrance of
the Leased Premises.

33. OCCUPANCY DELAY. In the event that the Leased Premises should not
be ready for occupancy for any reason, this Lease Agreement shall not be void or
voidable, and Landlord shall not be liable or responsible for any claims,
damages, or liabilities in connection therewith or by reason thereof, and the
term of this Lease Agreement shall be for the same term of months as set forth
in the Lease Agreement, but the beginning date shall be effective only from the
time that the Leased Premises are prepared for occupancy in accordance with the
terms and conditions set forth herein. Should the term of this Lease Agreement
begin on a date other than the beginning date, Landlord and Tenant will, at the
request of either, execute a declaration specifying the revised beginning the
term of this Lease Agreement. In such event rental under this Lease Agreement
shall not commence until said revised beginning date, and the stated term in
this Lease Agreement shall thereupon commence and the expiration date shall be
extended so as to give effect to the full stated term. Notwithstanding anything
to the contrary contained herein, Tenant may terminate this Lease if Landlord is
unable to deliver the Premises to Tenant by February 15, 2000. Within five (5)
days after Tenant receives Landlord's notice that the Leased Premises are ready
for occupancy, Tenant shall inspect the Leased Premises, and except for items
specified by Tenant to Landlord within five (5) days of Tenant's inspection,
Tenant shall be deemed to have accepted the Leased Premises in their then
condition, "as is." The existence of

"punch list" (as that term is generally used in the construction industry) items
shall not postpone the beginning date of this Lease Agreement.

34. PEACEFUL ENJOYMENT. Tenant shall occupy and may peacefully have,
hold, and enjoy the Leased Premises, subject to the other provisions hereof,
provided that Tenant pays the rent herein recited and performs all of Tenant's
covenants and agreements herein contained, including the observance of all
reasonable rules and regulations made by Landlord from time to time pursuant to
this Lease Agreement. It is understood and agreed that this covenant and any and
all other covenants of Landlord contained in this Lease Agreement shall be
binding upon Landlord and its successors only with respect to breaches occurring
during its and their respective ownerships of Landlord's interest hereunder.

35. PERSONAL PROPERTY TAX. Tenant shall be liable for and shall pay,
not later than ten (10) days before delinquency, all taxes levied against any
personal property or trade fixture placed by Tenant, in or about the Leased
Premises. Landlord may, after written notice to Tenant, pay any such levy or
tax, regardless of the validity of such levy, but only under proper protest if
so requested by Tenant in writing. Additionally, if the assessed value of
Landlord's property is increased by the inclusion of the value placed upon any
of the personal property or trade fixture of Tenant, Landlord may, after written
notice to Tenant, pay those taxes which are based upon such increased
assessment; regardless of the validity thereof, but only with proper protest if
so requested by Tenant in writing. In such an event Tenant shall, upon demand,
repay to Landlord taxes so levied and paid by Landlord, or that portion of such
taxes resulting from such increase in the assessment. Tenant shall have the
right, in the name of the Landlord and with Landlord's full cooperation, at no
cost to Landlord, to bring suit in any court of competent jurisdiction to
recover the amount of any such taxes so paid under protest. Any amounts so
recovered shall belong to Tenant.

36. PROHIBITED ACTIVITIES. Tenant shall not do or permit anything to be
done in or about the Leased Premises nor bring or keep anything therein which
will in any way increase the existing rate of or affect any fire or other
insurance upon the Project or any of its contents, or cause cancellation of any
insurance policy coveting said Project or any part thereof or any of its
contents. Tenant shall not do or permit anything to be done in or about the

objectionable purpose, nor shall Tenant cause, maintain, or permit any nuisance
in, on, or about the Leased Premises. Tenant shall not violate any of the rules
and regulations of the Project.

Lease Agreement for the purposes of regulating access, parking, use of the
common areas in the Leased Premises, and promoting safety, order, cleanliness,
and good service to the Project. Tenant will promptly comply with all such Rules
and Regulations. The parties acknowledge that the Rules and Regulations attached

however, Landlord, may at its option and at any time, reasonably amend and
modify said Rules and Regulations, and Tenant, upon receipt of written notice of
same, shall be obligated to comply with said Rules and Regulations. Landlord
shall uniformly apply and enforce all Rules and regulations against all tenants
of the Project.

41. SALES TAX. In addition to the rental payments hereunder, all state,

or repairs, alterations, or improvements necessary to be made, by strikes or
accident or by any cause beyond the reasonable control of Landlord, or by orders
or regulations of any federal, state, county, or municipal authority.

a. Any such interruption or suspension of services shall never
be deemed an eviction of or disturbance to Tenant's use and possession of the
Leased Premises or any part thereof, or render Landlord liable to Tenant for
damages by abatement of rent, or otherwise relieve Tenant of performance of
Tenant's obligation under this Lease Agreement. Landlord will use commercially

required to give Landlord under this Lease Agreement. In the event of the
enforcement by the mortgagee or the beneficiary under such mortgage or deed of
trust of the remedies provided for by law or by such mortgage or deed of trust,
or in the event Landlord gives a deed-in-lieu-of-foreclosure to such mortgagee
or trust deed beneficiary, Tenant will, upon request of any person or party
succeeding to the interest of Landlord as a result of such enforcement or
termination; automatically become the Tenant of such successor in interest
without change in the terms or other provisions of this Lease Agreement,
provided, however, that such successor in interest shall not be bound by (i) any
payment of rent or additional rent for more than one month in advance, (ii) any
amendment or modification of this Lease Agreement made without the written
consent of such mortgagee or such beneficiary or their successor in interest, or
(iii) any defaults of Landlord under this Lease Agreement which remain uncured

writing of such act or omission by Landlord, and (ii) Tenant has given the
mortgagee or trust deed beneficiary (a) thirty (30) days after written notice
of the same from Tenant, or such longer period as is reasonably necessary to
cure the act or ommission, provided that the cure is commenced within said

and no assignee shall conduct an audit for any period during which such
assignee was not in possession of the Leased Premises. Any refund due Tenant

51. TIME OF THE ESSENCE. Time shall be of the essence of this
Agreement.

52. TOTAL DESTRUCTION. A total destruction of the Project shall

immediately upon occurrence thereof, or delay in taking any action in connection
therewith, shall not waive such default, but said party shall have the right to
declare any such default at any time thereafter. Landlord's acceptance of rent
will not be deemed a waiver of any Tenant breach or default existing at the time
of payment, except a default in the payment of money, and then only to the
extent of the mount received by Landlord. Tenant's payment of Rent will not be
deemed a waiver of any Landlord breach or default existing at the time of
payment.

respective parties hereto shall and they hereby do waive trial by jury in any
action, proceeding or cross-action whatsoever arising out of or in any way
connected with this lease, the relationship of Landlord and Tenant, Tenant's use
or occupancy of the Premises, or any claim for injury or damage, or the
enforcement of any remedy under any statute or otherwise.

55. WAIVER OF TIME LIMITATIONS. In the event Tenant shall have any
claim or cause of action against Landlord arising out of or otherwise related to
this lease, Tenant must file such action with a court of competent jurisdiction
within the time period required by Minnesota law; otherwise, such claim or cause
of action shall be deemed waived and permanently barred by the passage of time
and be void.

the other from any and all liability or responsibility (to the other or to
anyone claiming through or under the other by way of subrogation or otherwise)
for any loss or damage to property caused by perils insured against by the
policies to be carried pursuant to this Lease, or if Landlord elects to self
insure, perils that would have been covered by the insurance required under
paragraph 25 even if the cause of such peril or damage shall have been the
negligence of the other party or of anyone for whom such party may be
responsible. Such waiver of subrogation shall be effective with respect to such
loss or damage, and each policy hereunder shall contain a clause or endorsement
to the effect that any such release shall not adversely affect or impair said
policies or prejudice the right of the releasing party to recover thereunder.
Landlord and Tenant each agree that their

policies shall include such a clause or endorsement. The failure to obtain a
clause or endorsement providing such waiver of subrogation shall in no manner
limit or restrict the validity and enforceability of the waivers of subrogation
herein contained.
