       4. Confidentiality: a. The parties expressly acknowledge that in the
course of their performance hereunder, they may learn or have access to certain
confidential, patent, copyright, business, trade secret, proprietary or other
like information or products of the other party or of third parties, including
but not limited to the other party's vendors, consultants, suppliers or
customers (the Information). Anything in the Agreement to the contrary
notwithstanding, the parties expressly agree that they will keep strictly
confidential any such Information that they learn.

       b. STATE FARM and CONSULTANT agree that, for the purposes of the
Agreement, third parties whose duties for STATE FARM require access to the
Information provided under the Agreement shall have access to the Information as
required by such duties, provided that: i) such third parties have agreed in
writing with either STATE FARM or CONSULTANT, in terms no less restrictive than
the confidentiality obligations of the Agreement, to keep confidential the
Information, ii) such third parties have agreed in writing with either STATE
FARM or CONSULTANT not to use the Information for their own benefit or the
benefit of any person or entity besides STATE FARM, and iii) STATE FARM, when

the license or use restrictions in the Agreement.

       c. CONSULTANT agrees not to use a third party's Information for its own
benefit or the benefit of any person besides STATE FARM.

refer to the party to the Agreement providing the Information to the other
party. The term "Receiving Party" shall refer to the party receiving the
Information in the course of its performance under this Agreement. The term

prior written approval of the Disclosing Party; (iii) are independently
developed by the Receiving Party; or (iv) are ordered to be produced by a court

the Receiving Party producing the Information agrees to notify the Disclosing
Party immediately and cooperate with the Disclosing Party in asserting a
confidential or protected status for the Information.

       e. Each party expressly further agrees that it shall return to Disclosing
Party upon the Disclosing Party's request any such Information and copies
thereof. The provisions of this Section 4 shall survive termination of the
Agreement.

expressly warrants to STATE FARM that:

             a. It has the ability and expertise to perform its responsibilities

             b. All materials (the "Materials") provided to STATE FARM by
CONSULTANT as a product of the Consulting Services, and the ideas and techniques
contained therein with respect to STATE FARM's business, shall be the sole and
absolute property of STATE FARM.

             c. Any Materials, or Consulting Services furnished or used under
this Agreement do not or will not infringe upon or violate a patent, copyright,
license or other property or proprietary right held, or misappropriate a trade
secret or other property right claimed by a third party. CONSULTANT at its own
expense shall defend and hold STATE FARM fully harmless against any action
asserted against STATE FARM (and specifically including costs and reasonable
attorneys' fees associated with any such action) to the extent that it is based
on a claim that use of the Materials within the scope of this Agreement
infringes any patent, copyright, license or other property right or proprietary
right of any third party. STATE FARM shall promptly notify CONSULTANT in writing
of any such claim. If as a result of any claim of infringement against any
patent, copyright, license or other property right or proprietary right of any
third party, STATE FARM is enjoined from using the Materials, or if either party
believes that the Materials are likely to become the subject of a claim of
infringement, STATE FARM at its option may terminate this Agreement and receive
a full refund of any fees paid hereunder, or request that CONSULTANT at its
option and expense procure the right for STATE FARM to continue to use the
Materials, or replace or modify the Materials so as to make it non-infringing.

       6. Work Made for Hire. The parties agree that the Materials produced
hereunder shall be considered a work made for hire. CONSULTANT further
transfers, assigns, sells, and conveys all rights to the Materials hereunder,
including but not limited to copyright, trademark, trade secret, and patent
rights.

       7. Use of State Farm Name. CONSULTANT shall not disclose or otherwise
identify STATE FARM or any of its affiliates or subsidiaries orally or in any of
CONSULTANT's advertising, publications, or other media to be displayed or
disseminated to CONSULTANT's customers or other parties.

       8. Independent Contractor. The parties expressly agree that the
CONSULTANT shall be an independent contractor for all purposes in the
performance of this Agreement and shall not be an employee of STATE FARM.

       9. Hold Harmless. CONSULTANT expressly agrees anything herein to the
contrary notwithstanding, that it shall indemnify and hold harmless STATE FARM
against any damages of any kind whatsoever, including costs and reasonable
attorneys' fees, STATE FARM shall incur as a result of the negligent acts or
omissions of CONSULTANT, its employees or agents, while on STATE FARM's
premises.

       10. LIMITATION OF LIABILITY. UNDER NO CIRCUMSTANCES WHATSOEVER SHALL
STATE FARM BE LIABLE TO CONSULTANT FOR ANY SPECIAL,

                                       -3-
<PAGE>

CONSEQUENTIAL, INDIRECT, OR INCIDENTAL DAMAGES OF ANY KIND WHATSOEVER. IN NO
EVENT WHATSOEVER SHALL STATE FARM'S LIABILITY TO CONSULTANT FOR ANY REASON
WHATSOEVER EXCEED IN THE AGGREGATE THE MUTUALLY AGREED TO COMPENSATION FOR
SERVICES PROVIDED UNDER THE WORK ORDER.

       11. Limitation of Actions. No action, whether in contract or tort,
including negligence, arising out of the performance of services under this
Agreement may be brought by either party more than eighteen (18) months after
the cause of action accrues.

       12. No Waiver. It is expressly understood that if either party, on any
occasion fails to perform any term of this Agreement, and the other party does
not enforce that term, the failure to enforce on that occasion shall not prevent
enforcement on any other occasion.

       13. Liquidated Damages. If either party neglects or fails to perform any
of its obligations under this Agreement and such failure continues for a period
of ten (10) days after notice thereof, the other party shall have the right to
terminate this Agreement. On written notification to CONSULTANT, STATE FARM may
at any time terminate the services of individual employees or agents of
CONSULTANT for reasons of performance or conduct. Both parties acknowledge that
the determination of actual damages in the case of nonperformance by either
party will be difficult or impossible. Both parties therefore agree that damages
under this Agreement will be as follows: In the event of CONSULTANT's default,
CONSULTANT shall forfeit its fees hereunder and no fee shall be payable to it;
in the event of STATE FARM's default, CONSULTANT shall receive only the portion
of the total fee representing work previously completed, but in no event shall
this amount exceed the total fee. This measure of damages shall be interpreted
as liquidated damages, and not as a penalty.

       14. Assignment. CONSULTANT may not assign its duties under the Agreement
to any other entity, including an entity which affiliates or merges with or
acquires CONSULTANT, except when such assignment is approved in advance by STATE
FARM in writing, which approval STATE FARM may in its sole discretion grant or
deny.

       15. Time is of the Essence. CONSULTANT acknowledges that time is of the
essence to STATE FARM.

       16. In the event STATE FARM, in its sole discretion, decides to loan
equipment to CONSULTANT to facilitate CONSULTANT's performance of the Consulting
Services, CONSULTANT shall be responsible for any loss or damage to such
equipment.

This Agreement together with the exhibit attached hereto shall be an agreement
binding upon each of the parties hereto, their successors, and to the extent
permitted their assigns. This Agreement shall be governed by the laws of the
State of Illinois without regard to its conflicts of law principles. This

Agreement cannot be amended or otherwise modified except as agreed to in writing
by each of the parties hereto. This Agreement and the exhibit attached hereto

matter hereof. This Agreement shall become effective on the date the second of

set forth herein shall remain applicable to all subsequent offers.

unusual expense to readapt the Premises to normal office use upon termination of
this Lease or increase (i) the cost of (a) construction or (b) insurance or (ii)
Taxes. All alterations and additions shall be part of the Premises unless and

as they were in at the beginning of the Term, reasonable wear and tear, damage

agents and Taking by eminent domain excepted. Tenant shall replace any glass
which may be damaged or broken with glass of the same quality at Tenant's
expense (if caused by the action of Tenant or its employees or agents). Tenant,
upon vacating the Premises, shall shampoo all carpets. Tenant further agrees to

additions becoming the property of the Landlord, except as to improvements or
additions which are personal property of Tenant and are removable without damage
to the Premises.

Premises at reasonable times, and that it will permit Landlord to enter the
Premises without charge or reduction in rent to make such repairs, improvements,
alterations or additions as may be required in order to comply with the
requirements of this Lease or of any public authority having jurisdiction, or to
make repairs which Tenant may have failed promptly to make pursuant to Tenant's
covenants hereunder. If such work is not of an emergency nature, it shall be
done only after reasonable notice to Tenant and in such a manner as will least
interfere with Tenant's operations.

the Premises free and clear of all tenants, occupants, liens, and encumbrances
holding by, through or under or caused by Tenant, as the case may be. Tenant

and tear, damage by fire or casualty only excepted) with all damages occasioned

                             Covenant Against Liens

11.01. Mechanics Liens. Landlord's right, title and interest in the Premises or
the Land or the Building shall not be subject to or liable for liens of
mechanics or materialmen for work done on behalf of Tenant in connection with
improvements to the Premises. Notwithstanding such restriction, if because of
any act or omission of Tenant, any mechanic's lien or other lien, charge or
order for payment of money shall be filed against any portion of the Premises or

operation of law) enter (nor may Landlord cause, suffer or permit Tenant to

Arrangement shall be absolutely void and

<PAGE>

ineffective for any purpose. Tenant shall not enter into any other Occupancy
Arrangement, either voluntarily or by operation of law, (other than with a
Person who is a Subsidiary Company or Affiliate of Tenant) without the prior
written consent of Landlord, such consent not to be unreasonably withheld or
delayed. Landlord may withhold approval of any Subtenant if Tenant is in default
under the Lease or if the Subtenant is one of Landlord's existing Tenants.

If the Landlord consents to such Occupancy Arrangement Tenant shall remain
liable for the payment and performance of the terms and covenants of this Lease.
Tenant agrees to disclose the terms of any sublease arrangement to Landlord
prior to signing said sublease. Landlord shall have the right of first refusal
on any sublease space under the same terms and conditions as offered to the
potential Subtenant. If Tenant enters into such an occupancy Arrangement, Tenant
shall pay to Landlord when received fifty percent (50%) of the Excess Rent (as
defined below), received in respect of such Occupancy Arrangement. Tenant agrees
to pay Landlord's reasonable legal fees associated with any sublease or
assignment.

Excess Rent shall be the amount by which (a) rent received from such subtenant
less all costs incurred by Tenant in procuring such subtenant, including without
limitations, broker's and attorney's fees and commissions exceeds (b) the Rent.

14.01. Tenant's Indemnity. To the fullest extent permitted by law, Tenant shall
indemnify and save harmless Landlord from and against any and all liability,
damage, penalties or judgments and from and against any claims, actions,

counsel fees arising from injury to person or property sustained by anyone in

defend any and all suits or actions (just or unjust) in which Landlord may be
impleaded with others upon any such above-mentioned matter, claim or claims,
except as may result from the acts as set forth in Section 14.02. All
merchandise, furniture, fixtures and property of every kind, nature and
description of Tenant or Tenant's employees, agents, contractors, invitees,
visitors or guests which may be in or upon the Premises, the Land or the
Building during the Lease Term shall be at the sole risk and hazard of Tenant,
and that if the whole or any part thereof shall be damaged, destroyed, stolen or
removed by reason of any cause or reason whatsoever, other than the negligence
or willful default of Landlord, no part of said damage or loss shall be charged
to or borne by Landlord.

14.02. Landlord's Liability. To the fullest extent permitted by law, Landlord
shall indemnify and save harmless Tenant from and against any and all liability,
damage, penalties or judgments and from and against any claims, actions,
proceedings and expenses and costs in connection therewith, including reasonable
counsel fees arising from injury to person or property sustained by anyone in
and about the Premises or the Building or the Land resulting from any act or
omission of Landlord, or Landlord's officers, agents, servants, employees,
contractors, sublessees or invitees. Landlord shall, at its own cost and
expense, defend any and all suits

                                       19
<PAGE>

or actions (just or unjust) in which Tenant may be impleaded with others upon
any such above-mentioned matter, claim or claims. All merchandise, furniture,
fixtures and property of every kind, nature and description of Tenant or
Tenant's employees, agents, contractors, invitees, visitors or guests which may
be in or upon the Premises, the Land or the Building during the Lease Term shall
be at the sole risk and hazard of Tenant, and that if the whole or any part
thereof shall be damaged, destroyed, stolen or removed by reason of any cause or
reason whatsoever, other than the negligence or willful default of Landlord, no
part of said damage or loss shall be charged to or borne by Landlord.

                                    Insurance

15.01. Liability Insurance. Tenant shall provide or cause to be provided at its
expense, and keep in force during the Lease Term, general comprehensive
liability insurance in a good and solvent insurance company or companies
licensed to do business in the Commonwealth of Massachusetts, selected by
Tenant, and reasonably satisfactory to Landlord, and in an amount reasonably
required by Landlord but in any event not less than One Million Dollars
($1,000,000.00) with respect to injury or death to any one person and One
Million Dollars ($1,000,000.00) with respect to injury or death to more than one
person in any one accident or other occurrence and One Hundred Thousand Dollars
($100,000.00) with respect to damages to property. Such policy or policies shall
include Landlord as an additional insured. Tenant agrees to deliver certificates
of such insurance to Landlord as of the date hereof and thereafter not less than
ten (10) days prior to the expiration of any such policy. Such insurance shall
not be cancelable without ten (10) days' written notice to Landlord.

15.02. Casualty Insurance. Tenant shall cause its improvements to the Premises
to be insured for the benefit of Landlord and Tenant as their respective
interests may appear, against loss or damage by fire and customary extended
coverage in an amount equal to (i) the replacement value thereof, if insurance
in such amount is available, or (ii) the amount necessary to avoid the effect of
co-insurance provisions of the applicable policies. Certificates thereof shall
be delivered to Landlord. Landlord shall, at Tenant's cost and expense,
cooperate fully with Tenant and execute any and all consents and other
instruments and take all other actions necessary to obtain the largest possible
recovery. Landlord shall not carry any insurance concurrent in coverage and
contributing in the event of loss with any insurance required to be furnished by
Tenant hereunder if the effect of such separate insurance would be to reduce the
protection or the payment to be made under Tenant's insurance.

                                   ARTICLE 16
                              Waiver of Subrogation

16.01. Waiver of Subrogation. All insurance policies carried by either party
covering the Premises, including but not limited to contents, fire and casualty
insurance, shall expressly waive any right on the part of the insurer to make
any claim against the other party. The parties hereto agree that their policies
will include such waiver clause or endorsement.

                                       20
<PAGE>

16.02. Waiver of Rights. Landlord and Tenant each hereby waive all claims,
causes of action and rights or recovery against the other and their respective
partners, agents, officers and employees, for any damage to or destruction of
persons, property or business which shall occur on or about the Premises and
shall result from any of the perils insured under any and all policies of
insurance maintained by Landlord and Tenant, regardless of cause, including the
negligence and intentional wrongdoing of either party and their respective
agents, officers and employees but only to the extent of recovery, if any, under
such policy or policies of insurance; provided, however, that this waiver shall
be null and void to the extent that any such insurance shall be invalidated by
reason of this waiver.

                              Damage or Destruction

17.01. Substantial Damage. If the Building or any part thereof shall be damaged
by fire or other casualty to the extent that substantial alteration or
reconstruction of the Building shall, in Landlord's or Tenant's opinion, be
required (whether or not the Premises shall have been damaged) or if as a result
any mortgagee of the Building requires that Proceeds payable be used to retire
the mortgage debt, either Landlord or Tenant may, terminate this Lease by
notifying Tenant in writing of such termination within thirty (30) days after
the date of such damage. If this Lease is so terminated, Rent shall be abated as
of the date of such damage.

17.02. Restoration. If this Lease is not terminated pursuant to Section 17.01,
Landlord shall, proceed with reasonable diligence to repair and restore the
Building (subject to Force Majeure) to substantially the same condition in which
it was immediately prior to the occurrence of the casualty to the extent of
Landlord's Work and the value of Landlord's Contribution. Tenant shall have the
right to terminate this Lease if such restoration is not complete within ninety
(90) days after the date of such damage. Landlord shall not be required to
rebuild, repair, or replace any part of Tenant's furniture, furnishings or
fixtures or equipment. Landlord shall not be liable for any inconvenience or
annoyance to Tenant or injury to the business of Tenant resulting in any way
from such damage or the repair thereof, except that, Landlord shall allow Tenant
a fair diminution of Rent during the time and to the extent the Premises are
wholly or partially untenable.

The term "untenable" shall mean damage or destruction to the Premises or the
Building which shall prevent the Tenant from carrying on its business in
substantially the manner in which it has previously conducted such business at
the Premises.

                                   ARTICLE 18
                                 Eminent Domain

18.01. Total Taking. If the Premises or the Building should be the subject of a
Total Taking, then this Lease shall terminate as of the date when physical
possession of the Building or the Premises is taken by the condemning authority.

                                       21
<PAGE>

18.02. Partial Taking. If there occurs a Partial Taking, Landlord (whether or
not the Premises are affected thereby) may terminate this Lease by giving
written notice thereof to Tenant within thirty (30) days after the right of
election accrues, in which event this Lease shall terminate as of the date when
physical possession of such portion of the Building or Premises is taken by the
condemning authority. If upon any such Partial Taking this lease is not
terminated, Rent shall be abated by an amount representing that part of the Rent
allocated to the portion of the Premises so taken and Landlord shall, at
Landlord's sole expense, restore and reconstruct the Building and the Premises
to substantially their former condition to the extent that the same, in
Landlord's judgment, may be feasible, but such work shall not exceed the scope
of Landlord's Work and the value of Landlord's Contribution.

18.03. Awards and Proceeds. All Proceeds payable in respect of a Taking shall be
the property of Landlord. Tenant hereby assigns to Landlord all rights of Tenant
in or to such Proceeds, provided that Tenant shall be entitled to separately
petition the condemning authority for a separate award for its moving expenses
and trade fixtures but only if such a separate award will not diminish the
amount of Proceeds payable to Landlord.

                                   ARTICLE 19
                                 Quiet Enjoyment

19.01. Landlord's Covenant. Provided that an Event of Default has not occurred
and is not then continuing, Tenant shall, subject to the Permitted Exceptions,
quietly have and enjoy the Premises during the Lease Term, without hindrance or
molestation from any Person lawfully claiming by, through or under Landlord.

19.02. Subordination. This Lease and all terms, covenants and provisions thereof
and all rights, remedies and options of Tenant under this Lease as the same may
hereafter be modified, amended or extended are and shall remain subject and
subordinate to any mortgage now or hereafter on the Building and to each advance
made or hereafter to be made under any mortgage, and to all renewals,
modifications, consolidations, replacements and extensions thereof and all
substitutions therefor. This Section 19.02 shall be self-operative and no
further instrument of subordination shall be required. In confirmation of such
subordination, Tenant shall execute and deliver promptly any certificate that
Landlord or any mortgagee may request in form satisfactory to Tenant. Tenant
waives the provisions of any statute or rule of law now or hereafter in effect
which may give or purport to give Tenant any right to terminate or otherwise
adversely affect this Lease or Tenant's obligations in the event of any
foreclosure proceeding is prosecuted or completed or in the event the Land, the
Building or Landlord's interest therein is sold at a foreclosure sale or by deed
in lieu of foreclosure. In the event that any mortgagee shall succeed to the
interest of Landlord then, this Lease shall nevertheless continue in full force
and effect and Tenant shall and does hereby agree to (1) attorn to such
mortgagee and to recognize such mortgagee as its Landlord, and upon request of
such mortgagee, Tenant shall execute and deliver to such mortgagee an agreement
of attornment in a form satisfactory to Tenant, or, at such mortgagee's option,
(2) enter into a new lease with such mortgagee, as Landlord, for the remaining
term of this Lease and otherwise on the identical terms and conditions and with
the same options, if any, then remaining, including all

                                       22
<PAGE>

modifications set forth in this Article provided that, notwithstanding anything
contained in this Article, the provisions of any mortgage held by such mortgagee
encumbering the Land and/or the Building (a "Mortgage") shall govern with
respect to the proceeds of any award in condemnation or of any fire or casualty
insurance policies affecting the Building.

19.03. Notice to Mortgagee. No act or failure to act on the part of Landlord
which would entitle Tenant under the terms of this Lease, or by law, to be
relieved of Tenant's obligations hereunder or to terminate this Lease, shall
result in a release or termination of such obligations or a termination of this
Lease unless Tenant shall have first given written notice of Landlord's act or
failure to act to Landlord's mortgagees of record, if any, specifying the act or
failure to act on the part of Landlord which could or would give basis to
Tenant's rights; and such mortgagees, after receipt of such notice, have failed
or refused to correct or cure the condition complained of within a reasonable
time thereafter. "Reasonable time" as used above shall mean a period of not more
than thirty (30) Calendar Days.

19.04. Other Provisions Regarding Mortgagees. (a) If this Lease or the Rent due
hereunder is assigned to a mortgagee as collateral security for a loan, no such
mortgagee shall be deemed to have assumed any of Landlord's obligations
hereunder solely as a result of said assignment. A mortgagee to whom this Lease
has been so assigned shall be deemed to have assumed such obligations only if
(i) by the terms of the instrument of assignment such mortgagee specifically
elects to assume such obligations and (ii) such mortgagee has (a) foreclosed its
mortgage (b) accepted a deed in lieu thereof, or (c) taken possession of the
Premises by entry or otherwise. Even if such mortgagee or its designee so
assumes the obligations of Landlord hereunder, (i) any such obligation under
Section 24.01 to return the Security Deposit to the Tenant shall be limited to
the amount actually received by the mortgagee, or its designee with respect
thereto, (ii) such mortgagee or its designee will be liable for breaches of any
of Landlord's obligations hereunder only to the extent such breaches occur
during the period of ownership by the mortgagee or its designee after
foreclosure (or any conveyance by a deed in lieu thereof), (iii) such mortgagee
or its designee shall not have any liability to Tenant in the event of damage or
destruction to the Building or the Premises, for any repairs, replacements,
rebuilding or restoration, unless required to be made under the provisions of
this Lease and in any event, except as can reasonably be accomplished from the
deductible and net proceeds of insurance actually received by, or made available
to such mortgagee or its designee and not applied in reduction and/or repayment
of the loan secured by any Mortgage and (iv) such mortgagee or its designee
shall not have any liability to Tenant for or be subject to any credits,
offsets, abatements, or claims against the rent under this Lease accruing to
Tenant as a result of any acts or omissions of Landlord, its successors or
assigns, occurring or committed prior to the date upon which such mortgagee or
its designee shall become the owner of or obtain possession or control of the
Building and the Land.

(b) If required by any such mortgagee, Tenant shall promptly join in any
non-disturbance agreement to indicate its concurrence with the provisions
hereof, in a form satisfactory to Tenant.

                                       23
<PAGE>

(c) If any such mortgagee or its designee shall succeed to the interest of
Landlord, or any successor to Landlord, any such mortgagee or its designee shall
have no personal liability as successor to Landlord and Tenant shall look only
to the estate and property of any mortgagee or its designee in the Land and in
the Building for the satisfaction of Tenant's remedies for the collection of a
money judgment (or other judicial process) requiring the payment of money in the
event of any default by any such mortgagee or its designee, as Landlord under
the Lease, and no other property or assets of any such mortgagee or its designee
shall be subject to levy, execution or other enforcement procedure for the
satisfaction of Tenant's remedies under or with respect to this Lease, the
relationship of Landlord and Tenant thereunder or Tenant's use or occupancy of
the Premises.

(d) Tenant agrees that no prepayment of rent or additional rent due under this
Lease of more than one month in advance, and no amendment, modification,
surrender or cancellation of this Lease shall be binding upon or as against any
such mortgagee whose name shall have been provided to Tenant in writing prior to
such amendment, modification, surrender or cancellation and as Landlord under
this Lease if it succeeds to that position, unless consented to in writing by
any such mortgagee.

(e) Any such mortgagee shall not be obligated to undertake or complete any
specific renovations or additions to the Premises specifically provided for in
this Lease to be performed by Landlord or pay the cost of any construction or
other special landlord work (either now or concurrently under way or hereafter
to be undertaken, whether or not the same is set forth in this Lease or any
other agreement).

(f) In the event any mortgagee requires, as a condition to providing any
construction or permanent financing or any refinancing for the Land and/or the
Building, that modifications to this Lease be obtained, and provided that such
modifications (i) are reasonable, (ii) do not adversely affect in a material
manner Tenant's use of the Premises as herein permitted, or Tenant's rights
hereunder and (iii) do not increase the Rent and other sums to be paid by Tenant
or other of Tenant's obligations hereunder, Landlord may submit to Tenant a
written amendment to this Lease incorporating such required changes, and Tenant
hereby covenants and agrees to execute and deliver such amendment to Landlord
within fifteen (15) days of Tenant's receipt thereof.

                           Defaults: Events of Default

20.01. Defaults. The following shall, if any requirement for notice or lapse of
time or both has not been met, constitute Defaults, and, if such conditions have
been met, constitute Events of Default hereunder:

(1) The occurrence of any event set forth in Article 21 hereof;

                                       24
<PAGE>

(2) The failure of Tenant to pay rent when the same shall be due and payable and
the continuance of such failure for a period of ten (10) days after receipt by
Tenant of notice in writing from Landlord specifying such failure;

(3) The failure of Tenant to observe any covenant made by it in Sections 13.01,
15.01 and 25.03 hereof; and

(4) The failure of Tenant to keep, observe or perform any of the other
covenants, conditions and agreements herein contained on Tenant's part to be
kept, observed or performed and the continuance of such failure without the
curing of same for a period of twenty (20) days after receipt by Tenant of
notice in writing from Landlord specifying in reasonable detail the nature of
such failure.

(5) If Tenant defaults under the terms of this Lease all of Tenant's options
contained in this Lease shall become null and void.

20.02. Tenant's Best Efforts. In the event that the Default of which Landlord
gives notice is of such a nature that it cannot be cured within such twenty (20)
day period, then such Default shall not be deemed to continue so long as Tenant,
after receiving such notice, proceeds to cure the Default as soon as reasonably
possible and continues to take all steps necessary to complete the same within a
period of time which, under all prevailing circumstances, shall be reasonable.
No Default shall be deemed to continue if and so long as Tenant shall be so
proceeding to cure the same in good faith or be delayed in or prevented from
curing the same by reason of Force Majeure.

                                   Insolvency

21.01. Insolvency. If (1) there occurs with respect to Tenant an Insolvency or
(2) any execution or attachment is issued against Tenant or any of its property
and as a result thereof the Premises are taken or occupied by some Person other
than the Tenant, except as may herein be permitted, then an Event of Default
hereunder shall be deemed to have occurred so that the provisions of Article 22
hereof shall become effective and Landlord shall have the rights and remedies
provided for therein.

                                   ARTICLE 22
                     Landlord's Remedies: Damages on Default

22.01. Landlord's Remedies. If an Event of Default shall occur and be
continuing, Landlord may, at its option, give to Tenant a notice terminating
this Lease upon a date specified in such notice, which date shall be not less
than three (3) Business Days after the date of receipt by Tenant of such notice
from Landlord, and upon the date specified in said notice, the term and estate
hereby vested in Tenant shall cease and any and all other right, title and
interest of Tenant hereunder shall likewise cease without further notice or
lapse of time, as fully and with

                                       25
<PAGE>

like effect as if the entire Lease Term has elapsed, but Tenant shall continue
to be liable to Landlord as hereinafter provided.

If such event of Default results from Tenant's failure to pay a charge for an
Additional Service pursuant to Section 8.03 hereof, Landlord may, without
further notice to Tenant, discontinue any or all of such Additional Services.

22.02. Surrender. Upon any termination of this Lease as the result of an Event
of Default, Tenant shall quit and peacefully surrender the Premises to Landlord.
Upon or at any time after any such termination, may without further notice,
enter the Premises and possess itself thereof by summary proceedings or
otherwise, and may dispossess Tenant and remove Tenant and all other Persons and
property from the Premises and may have, hold and enjoy the Premises and the
right to receive all rental income of and from the same.

22.03. Right to Relet. At any time or from time to time after any such
termination, Landlord may relet the Premises or any part thereof, in the name of
Landlord or otherwise, for such term or terms (which may be greater or less than
the period which would otherwise have constituted the balance of the Lease term)
and on such conditions (which may include concessions or free rent) as Landlord,
in its reasonable discretion, may determine and may collect and receive the
rents therefor. Landlord shall in no way be responsible or liable for any
failure to relet the Premises or any part thereof, or for any failure to collect
any rent due upon any such reletting. In the event of Tenant's default, Tenant
shall be liable to Landlord for all expenses including but not limited to legal,
brokerage, construction, vacancy, expenses associated with reletting, it's
construction and rent differential.

22.04. Survival of Covenants. No such termination of this Lease shall relieve
Tenant of its liability and obligations under this Lease and such liability and
obligations shall survive any such termination. Tenant shall indemnify and hold
Landlord harmless from all loss, cost, expense, damage or liability arising out
or in connection with such termination.

In the event of any such termination, Tenant shall pay to the Landlord the Rent
up to the date of such termination. Tenant shall also pay to Landlord, on
demand, as and for liquidated and agreed damages for Tenant's Default the
present value of:

(1) The aggregate Rent which would have been payable under this Lease by Tenant
from the date of such termination until the Stated Expiration Date minus the
fair rental value of the Premises, plus

(2) All of Landlord's reasonable estimate of expenses to be incurred in
connection with reletting the Premises, including, without limitation, all
repossession costs, brokerage commissions, legal expenses, reasonable attorneys'
fees, alteration costs, and expenses of preparation for such reletting.

If the Premises or any part thereof are relet by the Landlord before
presentation of proof of such liquidated damages to any court, commission or
tribunal, the amount of rent reserved

                                       26
<PAGE>

upon such reletting shall be, prima facie, the fair and reasonable rental value
for the part or the whole of the Premises so relet during the term of the
reletting.

Nothing herein contained shall limit or prejudice the right of the Landlord to
prove and obtain as liquidated damages by reason of such termination, an amount
equal to the maximum allowed by any statute or rule of law in effect at the time
when, and governing the proceedings in which, such damages are to be proved,
whether or not such amount be greater, equal to, or less than the amount of the
difference referred to above.

22.05. Right to Equitable Relief. If there shall occur a Default or threatened
Default, Landlord shall be entitled to enjoin such default or threatened Default
and shall have the right to invoke any right and remedy allowed at law or in
equity or by statute or otherwise as though re-entry, summary proceedings, and
other remedies were not provided for in this Lease.

22.06. Right to Self Help; Interest On Overdue Rent. If an Event of Default
shall occur and be continuing, either Landlord or Tenant shall have the right,
but shall not be obligated, to enter upon the Premises and to perform such
obligation notwithstanding the fact that no specific provision for such
substituted performance by either Landlord or Tenant is made in this Lease with
respect to such Default. In performing such obligation, either Landlord or
Tenant may make any payment of money or perform any other act. The aggregate of
(i) all sums so paid by either Landlord or Tenant (ii) interest (at the rate of
1-1/2% per month or the highest rate permitted by law, whichever is less) on
such sum plus all Rent not paid when due and (iii) all necessary incidental
costs and expenses in connection with the performance of any such act by either
Landlord or Tenant, shall be deemed to be Rent under this Lease and shall be
payable to either Landlord or Tenant immediately upon demand. Either Landlord or
Tenant may exercise the foregoing rights without waiving any other of its rights
or releasing either Landlord or Tenant from any of its obligations under this
Lease.

22.07. Further Remedies. Upon any termination of this Lease pursuant to Section
22.01, or at any time thereafter, Landlord may, in addition to and without
prejudice to any other rights and remedies Landlord shall have at law or in
equity, re-enter the Premises, and recover possession thereof and may dispossess
any or all occupants of the Premises in the manner prescribed by the statute
relating to summary proceedings, or similar statutes; but Tenant in such case
shall remain liable to Landlord as hereinbefore provided. In the event of
Tenant's default under Article 20 or 21, Tenant shall be liable to Landlord for
the legal expenses incurred in the event of Tenant's default.

23.01. No Waivers. Failure of Landlord to complain of any act or omission on the
part of Tenant no matter how long the same may continue, shall not be deemed to
be a waiver by said Landlord of any of its rights hereunder. No waiver by
Landlord at any time, expressed or implied, of any breach of any provision of
this Lease shall be deemed a waiver of a breach of any other provision of this
Lease or a consent to any subsequent breach of the same or any

                                       27

on account.
