                                        ---------------------------------------
or its registered assigns, is entitled to purchase from e4L, INC.,
a corporation organized under the laws of the State of Delaware (the "COMPANY"),
at any time or from time to time during the period specified in Section 2
hereof,
       ------------------------------------------------------------------------
fully paid and nonassessable shares of the Company's common stock, par value
$.01 per share (the "COMMON STOCK"), at an exercise price per share (the
"EXERCISE PRICE") equal to $1.6875. The number of shares of Common Stock
purchasable hereunder (the "WARRANT SHARES") and the Exercise Price are subject
to adjustment as provided in Section 4 hereof. The term "WARRANTS" means this
Warrant which is being issued pursuant to that certain Settlement Agreement,
dated as of the date hereof, by and among the Company and the other signatories
thereto (the "SETTLEMENT AGREEMENT").

This Warrant is subject to the following terms, provisions, and conditions:

    6. MANNER OF EXERCISE; ISSUANCE OF CERTIFICATES; PAYMENT FOR SHARES. Subject
to the provisions hereof, including, without limitation, the limitations
contained in Section 7 hereof, this Warrant may be exercised by the holder
hereof, in whole or in part, by the surrender of this Warrant, together with a
completed exercise agreement in the form attached hereto (the "EXERCISE
AGREEMENT"), to the Company during normal business hours on any business day at
the Company's principal executive offices (or such other office or agency of the
Company as it may designate by notice to the holder hereof), and upon (i)
payment to the Company in cash, by certified or official bank check or by wire
transfer for the account of the Company, of the Exercise Price for the Warrant
Shares specified in the Exercise Agreement or (ii) if the holder is permitted to
effect a Cashless Exercise (as defined in Section 11(c) hereof) pursuant to
Section 11(c) hereof, delivery to the

<PAGE>

Company of a written notice of an election to effect a Cashless Exercise for the
Warrant Shares specified in the Exercise Agreement. The Warrant Shares so
purchased shall be deemed to be issued to the holder hereof, as the record owner
of such shares, as of the close of business on the date on which this Warrant
shall have been surrendered, the completed Exercise Agreement shall have been
delivered, and payment shall have been made for such shares as set forth above
or, if such date is not a business date, on the next succeeding business date.
Certificates for the Warrant Shares so purchased, representing the aggregate
number of shares specified in the Exercise Agreement, shall be delivered to the
holder hereof within a reasonable time (but in no event later than fifteen
business days) after this Warrant shall have been so exercised (the "DELIVERY
PERIOD"). The certificates so delivered shall be in such denominations as may be
requested by the holder hereof and shall be registered in the name of such
holder or such other name as shall be designated by such holder. If this Warrant
shall have been exercised only in part, then, unless this Warrant has expired,
the Company shall, at its expense, at the time of delivery of such certificates,
deliver to the holder a new Warrant representing the number of shares with
respect to which this Warrant shall not then have been exercised.

    7. PERIOD OF EXERCISE.

       7.1 This Warrant is exercisable, at any time or from time to time on or
after the date of initial issuance of this Warrant (the "ISSUE DATE") and before
5:00 p.m., New York City time on, November 18, 2001 (the "EXERCISE PERIOD").

    8. CERTAIN AGREEMENTS OF THE COMPANY.  The Company hereby covenants and
agrees as follows:

       8.1 SHARES TO BE FULLY PAID. All Warrant Shares will, upon issuance in
accordance with the terms of this Warrant, be validly issued, fully paid, and
nonassessable and free from all taxes, liens, claims and encumbrances.

       8.2 RESERVATION OF SHARES. During the Exercise Period, the Company shall
at all times have authorized, and reserved for the purpose of issuance upon
exercise of this Warrant, a suf ficient number of shares of Common Stock to
provide for the exercise in full of this Warrant.

       8.3 LISTING. The Company shall promptly secure the listing of the shares
of Common Stock issuable upon exercise of this Warrant upon each national
securities exchange or automated quotation system, if any, upon which shares of
Common Stock are then listed or become listed (subject to official notice of
issuance upon exercise of this Warrant) and shall maintain, so long as any other
shares of Common Stock shall be so listed, such listing of all shares of Common
Stock from time to time issuable upon the exercise of this Warrant; and the
Company shall so list on each national securities exchange or automated
quotation system, as the case may be, and shall maintain such listing of, any
other shares of capital stock of the Company issuable upon the exercise of this
Warrant if and so long as any shares of the same class shall be listed on such
national securities exchange or automated quotation system.

       8.4 SUCCESSORS AND ASSIGNS. This Warrant will be binding upon any entity
succeeding to the Company by merger, consolidation, or acquisition of all or
substantially all of the Company's assets.

<PAGE>

    9. ANTIDILUTION PROVISIONS. The Exercise Price and the number of Warrant
Shares issuable hereunder and for which this Warrant is then exercisable
pursuant to Section 2 hereof shall be subject to adjustment from time to time as
provided in this Section 4.

In the event that any adjustment of the Exercise Price as required herein
results in a fraction of a cent, such Exercise Price shall be rounded up or down
to the nearest cent.

       9.1 SUBDIVISION OR COMBINATION OF COMMON STOCK. If the Company, at any
time after the Issue Date, subdivides (by any stock split, stock dividend,
recapitalization, reorganization, reclassification or otherwise) its shares of
Common Stock into a greater number of shares, then, after the date of record for
effecting such subdivision, the Exercise Price in effect immediately prior to
such subdivision will be proportionately reduced. If the Company, at any time
after the Issue Date, combines (by reverse stock split, recapitalization,
reorganization, reclassification or otherwise) its shares of Common Stock into a
smaller number of shares, then, after the date of record for effecting such
combination, the Exercise Price in effect immediately prior to such combination
will be proportionately increased.

       9.2 ADJUSTMENT IN NUMBER OF SHARES. Upon each adjustment of the Exercise
Price pursuant to the provisions of this Section 4, the number of shares of
Common Stock issuable upon exercise of this Warrant and for which this Warrant
is or may become exercisable shall be adjusted by multiplying a number equal to
the Exercise Price in effect immediately prior to such adjustment by the number
of shares of Common Stock issuable or for which this Warrant is or may become
exercisable (as applicable) upon exercise of this Warrant immediately prior to
such adjustment and dividing the product so obtained by the adjusted Exercise
Price.

       9.3 CONSOLIDATION, MERGER OR SALE. In case of any consolidation of the
Company with, or merger of the Company into any other corporation, or in case of
any sale or conveyance of all or substantially all of the assets of the Company
other than in connection with a plan of complete liquidation of the Company at
any time during the Exercise Period, then as a condition of such consolidation,
merger or sale or conveyance, adequate provision will be made whereby the holder
of this Warrant will have the right to acquire and receive upon exercise of this
Warrant in lieu of the shares of Common Stock immediately theretofore acquirable
upon the exercise of this Warrant, such shares of stock, securities, cash or
assets as were issued or payable with respect to or in exchange for the number
of shares of Common Stock immediately theretofore acquirable and receivable upon
exercise of this Warrant had such consolidation, merger or sale or conveyance
not taken place. In any such case, the Company will make appropriate provision
to insure that the provisions of this Section 4 hereof will thereafter be
applicable as nearly as may be in relation to any shares of stock or securities
thereafter deliverable upon the exercise of this Warrant.

       9.4 NOTICE OF ADJUSTMENT. Upon the occurrence of any event which requires
any adjustment of the Exercise Price, then, and in each such case, the Company
shall give notice thereof to the holder of this Warrant, which notice shall
state the Exercise Price resulting from such adjustment and the increase or
decrease in the number of Warrant Shares purchasable at such price upon
exercise, setting forth in reasonable detail the method of calculation and the
facts upon which such calculation is based.

       9.5 MINIMUM ADJUSTMENT OF EXERCISE PRICE. No adjustment of the Exercise
Price shall be made in an amount of less than 1% of the Exercise Price in effect
at the time such

<PAGE>

adjustment is otherwise required to be made, but any such lesser adjustment
shall be carried forward and shall be made at the time and together with the
next subsequent adjustment which, together with any adjustments so carried
forward, shall amount to not less than 1% of such Exercise Price.

       9.6 NO FRACTIONAL SHARES. No fractional shares of Common Stock are to be
issued upon the exercise of this Warrant, but the Company shall pay a cash
adjustment in respect of any fractional share which would otherwise be issuable
in an amount equal to the same fraction of the Market Price of a share of Common
Stock on the date of such exercise.

       9.7 CERTAIN EVENTS. If, at any time after the Issue Date, any event
occurs of the type contemplated by the adjustment provisions of this Section 4
but not expressly provided for by such provisions, the Company will give notice
of such event as provided in Section 4(d) hereof, and the Company's Board of
Directors will make an appropriate adjustment in the Exercise Price and the
number of shares of Common Stock acquirable upon exercise of this Warrant so
that the rights of the holder shall be neither enhanced nor diminished by such
event.

    10. ISSUE TAX. The issuance of certificates for Warrant Shares upon the
exercise of this Warrant shall be made without charge to the holder of this
Warrant or such shares for any issuance tax or other costs in respect thereof,
provided that the Company shall not be required to pay any tax which may be
payable in respect of any transfer involved in the issuance and delivery of any
certificate in a name other than the holder of this Warrant.

    11. NO RIGHTS OR LIABILITIES AS A SHAREHOLDER. This Warrant shall not
entitle the holder hereof to any voting rights or other rights as a shareholder
of the Company. No provision of this Warrant, in the absence of affirmative
action by the holder hereof to purchase Warrant Shares, and no mere enumeration
herein of the rights or privileges of the holder hereof, shall give rise to any
liability of such holder for the Exercise Price or as a shareholder of the
Company, whether such liability is asserted by the Company or by creditors of
the Company.

    12. TRANSFER AND REPLACEMENT OF WARRANT.

       12.1 RESTRICTION ON TRANSFER. This Warrant and the rights granted to the
holder hereof are transferable, in whole or in part, upon surrender of this
Warrant, together with a properly executed assignment in the form attached
hereto, at the office or agency of the Company referred to in Section 9 below,
PROVIDED, HOWEVER, that any transfer or assignment shall be subject to the
conditions set forth in Section 7(d) hereof. Until due presentment for
registration of transfer on the books of the Company, the Company may treat the
registered holder hereof as the owner and holder hereof for all purposes, and
the Company shall not be affected by any notice to the contrary. Notwithstanding
anything to the contrary contained herein, the registration rights described in
Section 8 hereof are not assignable.

       12.2 REPLACEMENT OF WARRANT. Upon receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction, or mutilation of
this Warrant and, in the case of any such loss, theft, or destruction, upon
delivery of an indemnity agreement reasonably satisfactory in form and amount to
the Company, or, in the case of any such mutilation, upon surrender and
cancellation of this Warrant, the Company, at its expense, will execute and
deliver, in lieu thereof, a new Warrant of like tenor.

<PAGE>

       12.3 CANCELLATION; PAYMENT OF EXPENSES. Upon the surrender of this
Warrant in connection with any transfer or replacement as provided in this
Section 7, this Warrant shall be promptly canceled by the Company.

       12.4 EXERCISE OR TRANSFER WITHOUT REGISTRATION. If, at the time of the
surrender of this Warrant in connection with any exercise, transfer, or exchange
of this Warrant, this Warrant (or, in the case of any exercise, the Warrant
Shares issuable hereunder), shall not be registered under the Securities Act and
under applicable state securities or blue sky laws, the Company may require, as
a condition of allowing such exercise, transfer, or exchange, (i) that the
holder or transferee of this Warrant, as the case may be, furnish to the Company
a written opinion of counsel (which opinion shall be in form, substance and
scope customary for opinions of counsel in comparable transactions) to the
effect that such exercise, transfer, or exchange may be made without
registration under the Securities Act and under applicable state securities or
blue sky laws, (ii) that the holder or transferee execute and deliver to the
Company an investment letter in form and substance acceptable to the Company
and (iii) that the transferee be an "ACCREDITED INVESTOR" as defined in Rule
501(a) promulgated under the Securities Act; PROVIDED that no such opinion,
letter, status as an "accredited investor" shall be required in connection with
a transfer pursuant to Rule 144 under the Securities Act.

    13. REGISTRATION RIGHTS. The initial holder of this Warrant is entitled to
the benefit of such registration rights in respect of the Warrant Shares as are
set forth in the Settlement Agreement.

    14. NOTICES. Any notices required or permitted to be given under the terms
of this Warrant shall be sent by certified or registered mail (return receipt
requested) or delivered personally or by courier or by confirmed telecopy, and

                                     DEMISE

     A. Landlord does hereby lease to Tenant and Tenant hereby lets from
Landlord, the Premises set forth in the Lease Schedule, which are situated in
that certain building (the "Building") located as denoted as the Property
Address in the Lease Schedule. The Building and the real estate on which it is
located are hereinafter referred to as the "Property". Tenant acknowledges that

conditions herein set forth and Tenant and Landlord covenant as a material part
of the consideration for this Lease to keep and perform each and all of said

                                       1.

                                     PURPOSE

     The Premises are to be used for the Purpose set forth in the Lease Schedule
and for no other purpose without the prior written consent of the Landlord.

                                       2.

                                      TERM

     The Lease Term shall be as set forth in the Lease Schedule except as

                                   POSSESSION

     A. If Landlord, for any reason whatsoever, cannot deliver possession of the

                                      -2-
<PAGE>

Premises to the Tenant on the intended date of the commencement of the Term,
this Lease shall not be void or voidable, nor shall the Landlord be liable to
Tenant for any loss or damage resulting therefrom. Under such circumstances, the
rent provided for herein shall not commence until possession of the Premises is
made available to Tenant and no such failure to give possession on the date of
commencement of the Term shall affect the validity of this Lease or the
obligations of the Tenant hereunder, and the Term shall be extended accordingly.

     B. Subject to the provisions of Appendix "C" hereto, Landlord, at its sole
cost and expense, shall provide and furnish, free and clear of any and all liens
and claims of laborers, artisans, materialmen, suppliers and subcontractors, the
following (collectively, the "Work"): all labor, materials, supplies, apparatus,
equipment, fixtures, tools and implements required to fully construct, perform
and completely finish in a good and workmanlike manner, in accordance with all
applicable laws, ordinances, rules and regulations (including, without
limitation, all zoning, building, flood plain and control and health, safety and
environmental protection laws, rules and regulations), and in accordance with
the approved TI Budget (as defined below), which TI Budget shall provide for a
maximum ten (10%) percent construction fee, (inclusive of profit, g&a and
general conditions): (a) Base Building substantial completion of shell and core,
and all common areas of the Building sufficient to permit Tenant's access to and
use of the Premises for the purpose of installation by Tenant of its furniture,
and partitions, as well as telephones and data systems; and (b) the construction
of the Premises in accordance with the TI Plans and Specifications (as
hereinafter defined in Appendix "C"). Subject to Section 27 hereof, Landlord
shall substantially complete the Work ("Substantial Completion") on or prior to
November 1, 1999, and if for any reason other than the default or delay of
Tenant hereunder or delay resulting from the following improvements which may
require longer delivery times than normal: specialty or decorative light
fixtures; VAV and fan powered boxes; Herculite doors; custom receptionist desk,
or any approved Change Order which causes delay beyond November 1, 1999 (and to
the extent any such Change Order is approved, such November 1, 1999 date shall
be extended for the period of time reflected in the Change Order to complete
same), Substantial Completion shall not occur on November 1, 1999 (or such later
date as set forth in such Change Order), then Tenant shall be entitled to one
day's rent abatement for each day after November 1, 1999 until Substantial
Completion shall have occurred, and in all events if Substantial Completion
shall not have occurred on or prior to February 1, 2000, (the "Election Date"),
Tenant, at its election by written notice to Landlord (the "Election Notice")
shall have the right to either: (x) terminate the Lease effective as of the date
of such Election Notice, in which event Tenant shall receive an immediate refund
of all amounts theretofore paid by Tenant under the Lease (including, without
limitation, all amounts expended by Tenant in respect of the Work within or for
the benefit of the Premises in excess of Landlord's Construction Allowance (as
defined below); or (y) complete that portion of the Work attributable to the
Premises provided that: (1) said portion of the Work shall be limited to the
Premises only, except for Work required to those portions of the Building
necessary for Tenant to complete the Work in the Premises sufficient for Tenant
to occupy and use the Premises as herein provided; (2) Landlord's failure to
substantially complete the Work on or before the Election Date results from the
failure of the General Contractor to perform the Work in a timely manner; (3)
all Work affecting Building systems or common elements shall be subject to
review and approved by Landlord's Architect; and (4) Tenant's exercise of the
foregoing election in this subsection (y) shall not act to release Landlord of
its obligations hereunder; the provisions of Section 27 hereof shall not
however, notwithstanding anything to the contrary herein contained, act in any
manner to delay the Election Date and limit the rights of Tenant to deliver the
Election Notice if Substantial Completion has not occurred on or prior to the
Election Date, provided however, delays or defaults on the part of Tenant shall
delay the Election Date and the right of the Tenant to give the Election Notice.

         C. The Premises shall be deemed to be ready for Tenant's occupancy if
only minor or insubstantial details of construction, decoration or mechanical
adjustments remain to be done in the Premises or any part thereof, or if the
delay in the availability of the Premises or any part thereof for occupancy
shall be due to special work, changes, alterations, or additions required or
made by Tenant in the layout or finishing of the Premises. Whether or not the
Premises are ready for occupancy shall be determined by; (i) the Jurisdiction in
which the

                                      -3-
<PAGE>

Property is located as set forth in the Lease Schedule, which shall evidence
same by authorizing Tenant's occupancy thereof, which authorization may be in
the form of oral or written permission to occupy which if in the form of written
permission, may be in the form of a temporary or permanent certificate of
occupancy; and (ii) a certification by Landlord's architect ("Landlord's
Architect") of such Substantial Completion, provided however, in the event a
licensed architect appointed by Tenant ("Tenant's Architect"), disagrees with
Landlord's Architect that Substantial Completion has occurred, then such two
architects shall jointly select a third architect, who shall be independent of
Tenant and Landlord, and such independent architect's determination shall be
final and binding upon the parties hereto. The cost of Tenant's and Landlord's
architects shall be borne by Tenant and Landlord, respectively, and if a third
architect is required as aforesaid, the cost of such third architect shall be
split equally between Tenant and Landlord. It is further understood that within
48 hours of initial occupancy, the parties shall jointly inspect the Premises
and prepare a "punch list" of incomplete items to be completed by Landlord
within a reasonable time after occupancy. Tenant agrees to provide a
supplemental "punch list" within thirty (30) days after occupancy encompassing
all items not then completed except for latent defects. Landlord agrees to the
extent reasonably possible to complete all "punch list items" within thirty (30)
days of receipt thereof.

                                       4.

subdivision of any thereof in the Jurisdiction in which the Property is located.
Taxes shall not include any income, capital stock, estate or inheritance taxes.

financial matters of Landlord) janitorial expenses, roof repairs, exterminating,
elevator maintenance, HVAC system maintenance, which Landlord shall be or become
obligated to pay in respect of a calendar year regardless of when such Operating
Costs were incurred which in accordance with generally accepted accounting or
management principles respecting first class buildings in the Jurisdiction in
which the Property is located would be considered as an expense of owning,
managing, operating, maintaining or repairing the Property.

          (ii) Operating Costs shall not include:

               (a)  The cost of alterations, capital improvements, equipment

                    compliance with applicable law for owning, operation or
                    management of the Building to the extent said compliance
                    relates to the failure of Landlord to perform its respective

               (e)  Repairs required to cure violations of laws enacted prior to

                    violations of laws enacted after the date of the Lease,

                    its respective agreements, covenants and liabilities
                    hereunder.

               (f)  The cost of repairs or replacements incurred by reason of
                    fire or other casualty or condemnation to the extent that

                    risk of such nature at the time of same; or (3) Landlord is
                    not fully compensated therefor due to the coinsurance
                    provisions of its insurance policies on account of
                    Landlord's failure to obtain a sufficient amount of coverage
                    against such risk. Notwithstanding the foregoing, Landlord's
                    reasonable insurance deductibles shall be deemed as
                    Operating Costs.

               (g)  Damage and repairs necessitated by the negligence or willful

                    such salaries are applicable and relate to performance of

                    of the terms of any leases with tenants or the defense of

                    occupied by tenants during all or a portion of any calendar

                    tenants using the service, such that tenants then occupying
                    space in the Building will pay their respective
                    proportionate shares of the amount of such variable
                    components of Operating Costs which would have been incurred
                    if the Building had been ninety-five (95%) percent occupied
                    during the entire

                                      -6-
<PAGE>

                    calendar year and Landlord had paid or incurred such costs
                    and expenses for the calendar year. Any such adjustments
                    shall be deemed costs and expenses paid or incurred by
                    Landlord and included in Operating Costs for such calendar
                    year.

                                       5.

Base Rate on Corporate Loans published by the Wall Street Journal from time to
time, but the payment of such interest shall not excuse or cure any default by

additional rent) shall be independent of any other covenant set forth in this
Lease.

     C. Base Rent and all of the rent provided herein shall be paid without
deduction or off-set in lawful money of the United States of America to c/o
Lawrence M. Freedman, Ash, Anos, Freedman & Logan, L.L.C., 77 West Washington

     B. It is further agreed between the parties hereto that in addition to the
rental provided for herein that Tenant shall also pay during the term of this
Lease, as additional rent, an amount equal to Tenant's Share of the Operating
Costs, provided however: (i) so long as Tenant is not in default, Tenant shall
not be responsible for any Operating Costs until the Rent Commencement Date; and
(ii) for the first five (5) years of the Term those components of Operating
Costs which are subject to Landlord's reasonable control shall not exceed one

deliver to Tenant a written statement setting forth Landlord's good faith
estimate of Tenant's Share of Taxes and Operating Costs (a "Taxes and Operating

Costs as estimated by Landlord. Not less than once in each calendar year after
the initial year of the Term, Landlord shall furnish to Tenant a written
statement showing in reasonable detail actual Operating Costs and Taxes for the
preceding year for which such statement is furnished and showing the amount, if
any, of rental adjustment due for such year. Landlord shall use its best efforts
to deliver such statement on or before March 31 of each year, but in no event
later than June 1.

     B. Subject to paragraph 6.D hereof, on the monthly rental payment date (the
"adjustment date") next following Tenant's receipt of each such annual
statement, Tenant shall pay to Landlord as additional rent an amount equal to
the sum of the net aggregate rental adjustment shown on each such annual
statement less the amount, if any, of the total estimated additional rent paid
by Tenant during the preceding calendar year.

     C. In the event that any such settlement required above indicates that the
total additional rent paid by Tenant during the preceding calendar year exceeds
the aggregate rental payable by Tenant for such calendar year, Landlord shall
apply such excess on any amounts of additional rent next falling due under this
Lease as long as Tenant is not then in default of any of the terms and
provisions of this Lease, or upon expiration of the Lease pay any such amount to
Tenant.

     D. The annual determination of Taxes and Operating Cost Statement shall be
prepared in accordance with generally acceptable cash basis accounting
principles. Tenant using either its own employee(s) or its certified public
accountant shall have the right to inspect at reasonable times and in a
reasonable manner, at the Landlord's office, such of the Landlord's books of
account and records as pertain to or contain information concerning the items
included in Operating Costs and Taxes for that year in order to verify the
amounts thereof. Any and all information obtained through the Tenant's
inspection with respect to financial matters (including, without limitation,
costs, expenses, income) and any and all other matters pertaining to the
Landlord and/or the Property as well as any compromise, settlement, or
adjustment reached between Landlord and Tenant relative to the results of any
such inspection shall be held in strict confidence by the Tenant and its
officers, agents, and employees; and Tenant shall cause its certified public
accountant and any of its officers, agents, and employees to be similarly bound.
If Tenant shall dispute any item or items included in the Operating Costs or
Taxes for such year, and such dispute is not resolved by the parties within
ninety (90) days after such statement is delivered to Tenant, then either party
may at its sole expense, within thirty (30) days thereafter, request that a firm
of independent certified public accountants mutually selected by Landlord and
Tenant ("Independent Review") render to the parties an opinion as to whether or
not the disputed item or items should have been included in the Operating Costs
and/or Taxes for such year; and the opinion of such firm on such matter shall be
conclusive and binding upon both parties, provided however, it shall be a
further condition of Tenant's right to conduct an Independent Review that the
firm conducting the Independent Review shall not be retained upon the basis of
all or a portion of its fees being contingent based upon the results of the
Independent Review. Landlord and Tenant agree that the firm's opinion shall be
confidential and shall not be disclosed to any other party whatsoever. In the
event such Independent Review discloses that the amount due from Tenant was
overstated in excess of five (5%)

                                      -8-
<PAGE>

percent on an annualized basis, Landlord shall bear the reasonable cost of such
Independent Review. In all other cases, Tenant shall bear the cost of such
Independent Review. Tenant employee(s) or certified public accountants may
examine the records of Landlord supporting the Taxes and Operating Cost
Statement at Landlord's or the Management Agent's office during normal business
hours within forty-five (45) days after the Taxes and Operating Statement is
furnished. Unless Tenant takes written exception to any item within ninety (90)
days after the furnishing of the Taxes and Operating Statement (which shall be
noted on the item as "paid under protest"), such Statement shall be considered
as final and accepted by Tenant. Tenant shall promptly tender payment for any
undisputed items and shall tender payment for any disputed items within ten (10)
days after the resolution of any such dispute.

     E. In no event shall any rent adjustment result in a decrease of the Base
Rent as set forth in the Lease Schedule.

     F. In the event of the termination of this Lease by expiration of the
stated term or for any other cause or reason whatsoever prior to the
determination of rental adjustment as hereinabove set forth, Tenant's agreement
to pay additional rental accrued up to the time of termination, and Landlord's
obligation to pay any sums to Tenant shall survive the expiration or termination
of the Lease.

                                       8.

                                  HOLDING OVER

     Should Tenant hold over after the termination of this Lease, by lapse of
time or otherwise, Tenant shall become a tenant from month to month only upon
each and all of the terms herein provided as may be applicable to such month to
month tenancy and any such holding over shall not constitute an extension of
this Lease; provided, however, during such holding over, Tenant shall pay Base
Rent and all Additional Rent (as heretofore adjusted, or as estimated by
Landlord) for the first thirty (30) days of such holdover at One Hundred
Twenty-Five (125%) Percent of the rate payable for Base Rent and all Additional
Rent for the month immediately preceding said holding over, and thereafter at
One Hundred Seventy-Five (175%) Percent of such rate, and in addition, Tenant
shall pay Landlord all direct damages, sustained by reason of Tenant's holding
over. The provisions of this paragraph do not exclude the Landlord's rights of
re-entry or any other right hereunder.

                                       9.

                                BUILDING SERVICES

     A. Landlord agrees to furnish to the Premises and the common areas during
reasonable hours (8:00 A.M. to 6:00 P.M. Mondays through Fridays and 8:00 A.M.
to 1:00 P.M. on Saturdays) except for the following legal holidays: Memorial
Day, July 4th, Labor Day, Thanksgiving, Christmas and New Years Day, and subject
to the rules and regulations of the Building, passenger and elevator service to
the extent applicable, heat and air conditioning in accordance with the design
for such systems and as required in Landlord's reasonable judgment for the
comfortable use and occupancy of the Premises and common areas, subject to
scheduling by Landlord. Landlord shall also furnish janitorial and cleaning
services in and about the Premises, Saturdays, Sundays excepted, comparable to
the standard janitor services furnished by other first class office buildings in
the Jurisdiction which the property is located and further agrees to maintain
and operate the Building in the manner and to the standard of other first class
office buildings in the Jurisdiction which the property is located. Landlord
further agrees, except for the interior of the Premises (other than Building
systems, equipment or components), to maintain the Property in good condition
and repair, including but not limited to snow removal, landscaping, and parking
lot, provided that the cost of same may be included in Operating Costs.

     B. Except to the extent same are caused by the failure of Landlord to
perform its respective agreements, covenants, and obligations hereunder, neither
Landlord nor any company, firm or individual, operating, maintaining, managing
or supervising the plant or

                                      -9-
<PAGE>

facilities furnishing the services included in Landlord's energy costs nor
any of their respective agents, beneficiaries, or employees, shall be liable
to Tenant, or any of Tenant's employees, agents, customers or invitees or
anyone claiming through or under Tenant, for any damages, injuries, losses,
expenses, claims or causes of action, because of any interruption or
discontinuance at any time for any reason in the furnishing of any of such
services, or any other service to be furnished by Landlord as set forth
herein; nor shall any such interruption or discontinuance relieve Tenant from
full performance of Tenant's obligations under this lease. Provided however
to the extent that the Premises are rendered untenantable for seventy-two
(72) consecutive hours or more as a result of the act or omission of
Landlord, rent shall abate until tenantability is restored.

     C. Electricity shall not be furnished by Landlord, but except as
otherwise hereinafter provided, shall be furnished by the approved electric
utility company serving the area ("Electric Service Provider"). Landlord
shall permit the Tenant to receive such service direct from such public
utility company at Tenant's cost, and shall permit Landlord's wire and
conduits, to the extent available, suitable and safely capable, to be used
for such purposes. Tenant shall make all necessary arrangements with the
local utility company for metering and paying for electric current furnished
by it to Tenant and Tenant shall pay for all charges for electric current
consumed on the Premises during Tenant's occupancy thereof. The electricity
used during the performance of janitorial service, the making of alterations
or repairs in the Premises, and for the operation of the Premises' air
conditioning system at times other than as provided herein; or the operation
of any special air conditioning systems which may be required for data
processing equipment or for other special equipment or machinery installed by
Tenant, shall be paid for by Tenant. Tenant shall make no alterations or
additions to the Building's electric equipment and/or appliances without the
prior written consent of the Landlord in each instance, which consent shall
not be unreasonably withheld. Tenant also agrees to purchase from the
Landlord or its agent all lamps, bulbs after the initial installation
thereof, ballasts and starters used in the Premises, provided however that
the availability, quality, and cost of any such items shall be comparable to
that available to Tenant from other suppliers. Tenant covenants and agrees
that at all times its use of electric current shall never exceed the capacity
of the feeders to the Building or the risers or wiring installed thereon. If
Tenant shall require water or electric current in excess of that which is
respectively obtainable from existing water pipes or electrical outlets and
normal for use of the Premises as general office space, Tenant shall first
procure the consent of Landlord, which Landlord may not unreasonably refuse.
If Landlord consents to such excess water or electric requirements, Tenant
shall pay all costs including but not limited to meter service and
installation of facilities necessary to furnishing such excess capacity.

     D. (1) Landlord has advised Tenant that presently Electric Service
Provider is the utility company selected by Landlord to provide electricity
service for the Building. Notwithstanding the foregoing, to the extent
permitted by law, Landlord shall have the right at any time and from time to
time during the Term to either contract for service from a different company
or companies providing electricity service (each such company hereinafter
described as an "Alternate Service Provider") or continued to contract for
service from the Electric Service Provider, provided that any portion of the
cost of such service to Tenant shall be based upon the cost thereof as
changed by said Alternate Provider with no additional fee to Landlord.

        (2) Tenant shall cooperate with Landlord, the Electric Service
Provider, and any Alternate Service Provider at all times, and as reasonably
necessary, shall allow Landlord, Electric Service Provider and any alternate
Service Provider reasonable access to the Building's electric lines, feeders,
risers, writing, and any other machinery within the Premises.

                                       10.

                            CONDITION OF THE PREMISES

     A. Subject to latent defects and "punch lists" heretofore referred to by
taking

                                      -10-

<PAGE>

possession of the Premises, Tenant shall be deemed to have agreed that the
Premises were as of the date of taking possession, in good order, repair and
condition. No promises of the Landlord to alter, remodel, decorate, clean or
improve the Premises or the Building and no representation or warranty
expressed or implied, respecting the condition of the Premises or the
Building has been made by the Landlord to Tenant, unless the same is
contained herein or made a part hereof.

     B. Tenant shall, at its own expense, keep the Premises in good repair
and tenantable condition, and shall promptly and adequately repair all
damages to the Premises under the supervision and with the approval of
Landlord and within a reasonable period of time as specified by Landlord,
loss by ordinary wear and tear, fire and other casualty excepted. If Tenant
does not do so promptly and adequately, Landlord may, but need not, make such
repairs and Tenant shall pay Landlord immediately upon request by Landlord.

     C. The parties acknowledge that the Americans With Disabilities Act of
1990 (42 U.S.C. 12101 et seq.) and regulations and guidelines promulgated
thereunder, as all of the same may be amended and supplemented from time to
time (collectively referred to herein as the "ADA") establish requirements
under Title III of the ADA ("Title III") pertaining to business operations,
accessibility and barrier removal, and that such requirements may be unclear
and may or may not apply to the Premises and the Building depending on, among
other things: (1) whether Tenant's business operations are deemed a "place of
public accommodation" or a "commercial facility," (2) whether compliance with
such requirements is "readily achievable" or "technically infeasible," and
(3) whether a given alteration affects a "primary function area" or triggers
so-called "path of travel" requirements. Landlord represents that the
Building, as of the date of commencement hereof complies with Title III.
Tenant shall be responsible for all Title III compliance and costs in
connection with the Premises (including structural work, if any, and
including leasehold improvements or other work to be performed in the
Premises under or in connection with this Lease) to the extent that same
arises out of matters specific to Tenant's activities or operations or
resulting from alterations to the Premises made by Tenant.

                                       11.

                                 USES PROHIBITED

     Tenant shall not use, or permit the Premises or any part thereof to be
used, for any purpose or purposes other than as specified the Lease Schedule.
No use shall be made or permitted to be made of the Premises, nor acts done,
which will increase the existing rate of insurance upon the Building, or
cause a cancellation of any insurance policy covering the Building, or any
part thereof, nor shall Tenant sell, or permit to be kept, used or sold, in
or about the Premises, any article which may be prohibited by Landlord's
insurance policies. Tenant shall not commit or suffer to be committed, any
waste upon the Premises, or any public or private nuisance or other act or
thing which may disturb the quiet enjoyment of any other Tenant in the
Building, nor, without limiting the generality of the foregoing, shall Tenant
allow the Premises to be used for any improper, immoral, unlawful or
objectionable purpose. Tenant agrees at all times to cause the Premises to be
operated in compliance with all federal, state, local or municipal laws,
statutes, ordinances, and rules and regulations, including but not limited to
those relating to zoning, environmental protection, health, and safety.
Tenant further agrees to promptly cure any such violation at its own expense,
and shall furthermore defend and indemnify Landlord, beneficiaries,
mortgagees, and officers, agents, and employees thereof respectively, for any
and all liability, loss, costs (including attorneys' fees and expenses),
damages, responsibilities or obligations incurred as a result of any
violation of any of the foregoing. Tenant shall upon request of Landlord
certify in writing that it has not received any notice of non-compliance with
applicable local, state and federal environmental rules, regulations,
statutes and laws for the preceding year. At the request of the Landlord,
Tenant shall submit to the Landlord, or shall make available for inspection
and copying upon reasonable notice and at reasonable times, any or all of the
documents and materials prepared by or for Tenant pursuant to any
environmental law or regulation or submitted to any governmental regulatory
agency in conjunction therewith. Upon reasonable

                                      -11-

<PAGE>

notice except in cases of emergency, Landlord shall have reasonable access to
the Premises to inspect the same to confirm that the Tenant is using the
Premises in accordance with local, state and federal environmental rules,
regulations, statutes and laws. Tenant shall, at the request of the Landlord
and at the Tenant's expense, conduct such testing and analysis as is
necessary to ascertain whether the Tenant is using the Premises in compliance
with all local, state and federal environmental rules, regulations, statutes
and laws, provided however, Landlord shall not request that Tenant conduct
such tests unless Landlord has a reasonable basis for belief that Tenant may
be in violation of the foregoing rules, regulations, statutes, or laws. Said
tests shall be conducted by qualified independent experts chosen by the
Tenant and subject to Landlord's reasonable approval. Copies of reports of
any such tests shall be provided to the Landlord. The provisions within this
paragraph shall survive termination of this Lease and shall be binding upon
and shall inure to the benefit of the parties hereto, their respective
successors and assigns, and mortgagees thereof

                                       12.

                               COMPLIANCE WITH LAW

     Tenant shall not use the Premises or permit anything to be done in or
about the Premises which in any way conflict with any law, statute, ordinance
or governmental rule or regulation now in force or which may hereafter be
enacted or promulgated. Tenant shall, at its sole cost and expense, promptly
comply with all laws, statutes, ordinances and governmental rules,
regulations or requirements now in force or which may hereafter be in force
and with the requirements of any board of fire underwriters or other similar
body now or hereafter constituted relating to or affecting the condition, use
or occupancy of the premises, excluding structural changes not related to or
affected by Tenant's improvements or acts. The judgment of any court of
competent Jurisdiction or the admission of Tenant in an action against Tenant
whether Landlord be a party thereto or not, that Tenant has violated any law,
statute, ordinance or governmental rule, regulation or requirement shall be
conclusive of that fact as between Landlord and Tenant.

                                       13.

                             ALTERATIONS AND REPAIRS

     A. Tenant shall keep the Premises in good condition and repair ordinary
wear and tear and loss by fire and other casualty excepted, and shall not do
any painting or decorating, or erect any partitions, make any alterations in
or additions, changes or repairs to the Premises without the Landlord's prior
written approval in each and every instance, such consent not to be
unreasonably withheld, provided however, Landlord's consent shall not be
required so long as: (i) Landlord is given prior notice thereof; (ii)
Landlord is given as-built plans upon completion for alterations and repairs
which are affixed to the Premises; (iii) structure, roof, and building
systems are not affected; (iv) the aggregate cost does not exceed FIFTY
THOUSAND ($50,000.00) DOLLARS; and (v) Tenant obtains all necessary permits.
It shall not be unreasonable for Landlord to withhold approval of any
alteration or addition which impacts structure or any Building system, or
which would otherwise result in requiring additional improvements to the
Premises and/or the Property, or result in a labor dispute. Unless otherwise
agreed by Landlord and Tenant in writing, all such work shall be performed
either by or under the direction of Landlord, but at the cost of Tenant.
During the term of this Lease, no work shall be performed by or under the
direction of Tenant without the express written consent of Landlord. Unless
otherwise provided by written agreement, all alterations, improvements, and
changes shall remain upon and be surrendered with the Premises, excepting
however that at Landlord's option, Tenant shall, at its expense, when
surrendering the Premises, remove from the Premises and the Building all
alterations, improvements, and changes (other than initial Work) and further
provided that Tenant shall, on the election of Landlord, remove any trade
fixtures provided the Premises are restored to a condition reasonably
satisfactory to Landlord. If Tenant does not remove said additions,
decorations, fixtures, hardware, non-trade fixtures and improvements after
request to do so

                                      -12-

<PAGE>

by Landlord, Landlord may remove the same and Tenant shall pay the cost of such
removal to Landlord upon demand. Except to the extent of Landlord's negligent or
willful act or omission, Tenant hereby agrees to hold Landlord and Landlord's
beneficiaries, their agents and employees harmless from any and all liabilities
of every kind and description which may arise out of or be connected in any way
with said alterations or additions. Any mechanic's lien filed against Premises,
or the Building or the Property, for work claimed to have been furnished to
Tenant shall be discharged of record by Tenant within ten (10) days thereafter,
at Tenant's expense, provided however Tenant shall have the right to contest any
such lien on the posting of reasonably sufficient security.

     B. Tenant shall, at the termination of this Lease, surrender the Premises
to Landlord in as good condition and repair as reasonable and proper use thereof
will permit, loss by ordinary wear and tear, fire or other casualty excepted.

                                       14.

                        ABANDONMENT OF PERSONAL PROPERTY

     During the term, if Tenant shall abandon, vacate or surrender (whether at
the end of the stated term or otherwise) the Premises, or be dispossessed by
process of law, or otherwise, any personal property belonging to Tenant and left
on the Premises shall be deemed abandoned, at the option of the Landlord.

                                       15.

                            ASSIGNMENT AND SUBLETTING

     A. Tenant shall not assign this Lease, or any interest therein and shall
not sublet the Premises or any part thereof, or any right or privilege
appurtenant thereto, or suffer any other person to occupy or use the Premises,
or any portion thereof, without the written consent of Landlord first had and
obtained, which consent shall not be unreasonably withheld or delayed.
Notwithstanding the foregoing, Landlord's consent shall not be required for
assignments or subleases of all or a major portion of the Premises, so long as:
(i) the use of the Premises does not change and the proposed assignee or
sublessee is not a governmental agency, school, or medical office; (ii) Landlord
is given prior notice thereof; and (iii) the net worth of such assignee or
sublessee is not less than THIRTY-FIVE MILLION ($35,000,000.00) DOLLARS as
evidenced by an audited financial statement prepared in accordance with
generally accepted amounting principles by a nationally recognized public
accounting firm. In the event of an assignment or sublease which meets the
foregoing criteria in sections (i)-(iii) of this Section 15.A, Tenant and
Guarantor shall be released from further liability. Otherwise no such assignment
or sublease shall release Tenant or Guarantor of their respective obligations
under this Lease.

     B. Except for assignments and subleases to affiliates or subsidiaries (for
which no consent of Landlord shall be required under A above if Guarantor shall
remain liable under its Guaranty), Tenant shall, by notice in writing, advise
Landlord of its intention from on and after a stated date (which shall not be
less than sixty (60) days after the date of Tenant's notice) to assign or to
sublet any such part of all of the Premises for the balance or any part of the
Term, and, in such event Landlord shall have the right, to be exercised by
giving written notice to Tenant thirty (30) days after receipt of Tenant's
notice, to recapture the space described in Tenant's notice and such recapture
notice shall, if given, cancel and terminate this Lease with respect to the
space therein described as of the date stated in Tenant's notice. Tenant's said
notice shall state the name and address of the proposed subtenant or assignee,
the proposed subtenant's or assignee's intended use of the Premises, and shall
include the potential subtenant's or assignee's most current certified financial
statement, and a true and complete copy of the proposed assignment or sublease
or form of assignment shall be delivered to Landlord with said notice. If
Tenant's notice shall cover all of the space hereby demised and if Landlord
shall give the aforesaid recapture notice with respect thereto, the

                                      -13-
<PAGE>

Term of this Lease shall expire and end on the date stated in Tenant's notice
as fully and completely as if that date had been herein definitely fixed for
the expiration of the Term. If, however, this Lease be canceled pursuant to
the foregoing with respect to less than the entire Premises, the rental and
the escalation percentages herein reserved shall be adjusted on the basis of
the number of square feet retained by Tenant in proportion to the rent and
escalation percentages reserved in this Lease, and this Lease as so amended
shall continue thereafter in full force and effect. If Landlord, upon
receiving Tenant's said notice with respect to any such space, shall not
exercise its right to cancel as aforesaid, Landlord will not unreasonably
withhold its consent to Tenant's assigning or subletting the space covered by
its notice, provided; (i) at the time thereof Tenant is not in default under
this Lease, (ii) Landlord, in its sole discretion reasonably exercised,
determines that the reputation, business, proposed use of the Premises and
financial responsibility of the proposed sublessee or occupant, as the case
may be, of the Premises are satisfactory to Landlord, (iii) any assignee or
subtenant shall expressly assume all the obligations of this Lease on
Tenant's part to be performed; (iv) such consent if given shall not release
Tenant of any of its obligations (including, without limitation, its
obligation to pay rent) under this Lease, (v) Tenant agrees specifically to
pay over to Landlord, as additional rent, all sums received by Tenant under
the terms and conditions to such assignment or sublease, which are in excess
of the amounts otherwise required to be paid pursuant to the Lease; (vi) a
consent to one assignment, subletting occupation or use shall be limited to
such particular assignment, sublease or occupation and shall not be deemed to
constitute Landlord's consent to an assignment or sublease to or occupation
by another person. Any such assignment or subletting without such consent
shall be void and shall, at the option of Landlord, constitute a default
under this Lease. Tenant will pay all of Landlord's costs associated with any
such assignment or subletting including but not limited to reasonable legal
fees; and (vii) the person or entity to whom Tenant wishes to assign or
sublet is not (nor, immediately prior to such assignment or sublease, was) a
tenant or occupant in the Buildings; or any other building owned or operated
by Landlord or any affiliate thereof, in the same complex as the Building.

                                       16.

                                      SIGNS

     Tenant shall not place or affix any exterior or interior signs visible from
the outside of the Premises. For purposes of this Lease, "signs" shall include
all signs, designs, monuments, logos, banners, projected images, pennants,
decals, advertisements, pictures, notices, lettering, numerals, graphics, or
decorations. Notwithstanding the foregoing, Landlord agrees to provide, at
Landlord's cost which shall not be included in Tenant's allowance for the Work,
a monument sign upon which Tenant may, at Tenant's expense, including
installation of Tenant's letters, have identification on approximately fifty
(50%) percent thereof, which sign shall be subject to the reasonable approval of
Landlord and the approval of the Jurisdiction in which the Property is located.
Landlord further agrees that unless provided to Tenant, no other tenant will be
entitled to a sign on the Building, nor shall any other tenant have more
prominent signage than Tenant.

                                       17.

                     DAMAGE TO PROPERTY - INJURY TO PERSONS

     A. Tenant, as a material part of the consideration to be rendered to
Landlord under this Lease, to the extent permitted by law, hereby waives all
claims except claims caused by or resulting from the non-performance of the
Landlord, willful or negligent act or omission of Landlord, its agents, servants
or employees which Tenant or Tenant's successor or assigns may have against
Landlord, its agents, servants, or employees for loss, theft or damage to the
property and for injuries to persons in, upon or about the Premises or the
Building from any cause whatsoever. Tenant will hold Landlord, its agents,
servants, and employees exempt and harmless from and on account of any damage or
injury to any person, or to the goods, wares, and merchandise of any person,
arising from the uses of the Premises by Tenant or arising

                                      -14-
<PAGE>

from the failure of Tenant to keep the Premises in good condition as herein
provided if non-performance by the Landlord or negligence of the Landlord, its
agents, servants or employees does not contribute hereto. Neither Landlord nor
its agents, servants, employees shall be liable to Tenant for any damage by or
from any act or negligence of any co-tenant or other occupant of the same
Building, or by any owner or occupant of adjoining or contiguous property,
provided however, that the provisions of this paragraph shall not apply to
negligent or willful act or omission of Landlord or misconduct of any such
individuals or entities. Tenant agrees to pay for all damage to the Building or
the Premises, as well as all damage to tenants or occupants thereof caused by
Tenant's misuse or neglect of the Premises, its apparatus or appurtenances or
caused by any licensee, contractor, agent or employees of Tenant.

     B. Particularly, but not in limitation of the foregoing paragraph, all
property belonging to Tenant or any occupant of the Premises that is in the
Building or the Premises shall be there at the risk of Tenant or other person
only, and Landlord or its agent, servants, or employees (except in case of
non-performance by the Landlord or negligent or willful act or omission of
Landlord or its agents, servants, employees) shall not be liable for: damage to
or theft of or misappropriation of such property; nor for any damage to property
entrusted to Landlord, its agents, servants, or employees, if any; nor for the
loss of or damage to any property by theft or otherwise, by any means
whatsoever, nor for any injury or damage to persons or property resulting from
fire, explosion, falling plaster, steam, gas, electricity, snow, water or rain
which may leak from any part of the Building or from the pipes, appliances or
plumbing works therein or from the roof, street or subsurface or from any other
place or resulting from dampness or any other cause whatsoever; nor for
interference with the light or other incorporeal hereditaments, nor for any
latent defect in the Premises or in the Building. Tenant shall give prompt
notice to Landlord in case of fire or accidents in the Premises or in the
Building or of defects therein or in the fixtures or equipment.

     C. In case any action or proceeding be brought against Landlord by reason
of any obligation on Tenant's part to be performed under the term of this Lease,
or arising from any act or negligence of the Tenant, or of its agents or
employees, Tenant, upon notice from Landlord shall defend the same at Tenant's
expense by counsel reasonably satisfactory to Landlord.

     D. Tenant shall maintain in full force and effect during the term of this
Lease (including any period prior to the beginning of the term during which
Tenant has taken possession and including also any period of extension of the
Term in which Tenant obtains possession), in responsible companies approved by
Landlord (i) special causes of loss coverage insurance covering all Tenant's
property in, on or about the Premises, with full waiver of subrogation rights
against Landlord in an amount equal to the full replacement cost of such
Property, and (ii) commercial general liability insurance including products and
completed operations insuring Tenant against all claims, demands or action for
bodily injury and property damage with limits of not less than TWO MILLION
($2,000,000.00) DOLLARS or THREE MILLION ($3,000,000.00) DOLLARS each occurrence
and in the aggregate. A separate limit of TWO MILLION ($2,000,000.00) DOLLARS or
THREE MILLION ($3,000,000.00) DOLLARS each occurrence and in the aggregate shall
be provided for products and completed operations or such other amounts as
Landlord may reasonably require from time to time and (iii) rental insurance
equal to one year's rent insurance naming Landlord as loss payee. All liability
policies shall cover the entire demised premises. Landlord shall maintain in
full force and effect during the term of this Lease special causes of loss
coverage insurance for the full replacement cost of the Building, the premium
for which shall be included in the Operating Costs.

     E. All such policies shall name Landlord, any mortgagees of Landlord, and
all other parties designated by Landlord as additional parties insured. All
insurance policies shall indicate that at least thirty (30) days prior written
notice shall be delivered to all additional parties insured by the insurer prior
to modification, termination, or cancellation of such insurance and Tenant shall
provide Certificates of Insurance, not less than ten (10) days prior to the
Commencement Date, evidencing the aforesaid coverage to all insured parties.
Failure of Tenant to provide the insurance coverage set forth in subparagraphs
(ii) and (iii) in the

                                      -15-
<PAGE>

immediately preceding paragraph shall entitle Landlord to either (a) treat said
failure as a default and/or (b) obtain such insurance and charge Tenant the
premiums therefor plus interest thereon as additional rent. Tenant shall not
violate or permit a violation of any of the conditions or terms of any such
insurance policies and shall perform and satisfy all reasonable requirements of
the insurance company issuing such policies. With respect to any insurance
policy procured to comply with any financial assurance requirement imposed by
any state or federal law or regulation, or to any other casualty, property, or
environmental impairment insurance purchased by Tenant, such policy or policies
shall name Landlord and any mortgagees of Landlord as additional parties
insured.

                                       18.

                              DAMAGE OR DESTRUCTION

     In the event the Premises or the Building are damaged by fire or other
insured casualty and the insurance proceeds have been made available therefor by
the holder or holders of any mortgages or deeds of trust covering the Building,
the damage shall be repaired by and at the expense of Landlord to the extent of
such insurance proceeds available therefor, provided such repairs can, in
Landlord's reasonable opinion, be made within one hundred eighty (180) days
after the occurrence of such damage without the payment of overtime or other
premiums. Until such repairs are completed, the rent shall continue to be paid
by Tenant's rental insurance and shall otherwise be abated to the extent the
Premises are rendered untenantable. If repairs cannot, in Landlord's reasonable
opinion be made within one hundred eighty (180) days, Landlord shall notify
Tenant within thirty (30) days the occurrence of such damage of its
determination, in which event, or in the event such repairs are commenced but
are not substantially completed within one hundred eighty (180) days of the date
of such occurrence, either party may, by written notice to the other, cancel
this Lease as of the date of the occurrence of such damage. In the event
Landlord commences repairs, and same are not substantially completed within one
hundred eighty (180) days after occurrence of such damage, Tenant may elect to
terminate the Lease. Except as provided in this Section, there shall be no
abatement of rent and no liability of Landlord by reason of any injury to or
interference with Tenant's business or property arising from any such fire or
other casualty or from the making or not making of any repairs, alterations or
improvements in or to any portion of the Building or the Premises or in or to
fixtures, appurtenances and equipment therein. Tenant understands that Landlord
will not carry insurance of any kind on Tenant's furniture or furnishings or on
any fixtures or equipment removable by Tenant under the provisions of this
Lease and that Landlord shall not be obliged to repair any damage thereto or
replace the same. Landlord shall not be required to repair any injury or damage
caused by fire or other cause, or to make any repairs or replacements to or of
improvements installed in the Premises by or for Tenant.

                                       19.

                                ENTRY BY LANDLORD

     Landlord and its agents shall have the right to enter the Premises at all
reasonable times (upon reasonable notice except in cases of emergency) for the
purpose of examining or inspecting the same, to supply janitorial services and
any other service to be provided by Landlord to Tenant hereunder or any other
tenants, to show the same to prospective purchasers or tenants of the Building,
and make such alterations, repairs, improvements, or additions, whether
structural or otherwise, to the Premises or to the Building as Landlord may deem
necessary or desirable. Landlord may enter by means of a master key without
liability to Tenant except for any failure to exercise due care for Tenant's
property and without affecting this Lease. Landlord shall use reasonable efforts
on any such entry not to unreasonably interrupt or interfere with Tenant's use
and occupancy of the Premises. Landlord agrees not to enter the Premises to show
same to prospective tenants prior to ten (10) months before scheduled expiration
of the Lease, which time shall be extended to twelve (12) months in the event
Tenant has not elected to renew this Lease for any subsequent

                                      -16-

period.

                                       20.

                            INSOLVENCY OR BANKRUPTCY

     A. In the event that Tenant shall become a debtor under Chapter 7, 11 or 13
of the Bankruptcy Code ("Debtor") and the trustee ("Trustee") or Tenant shall
elect to assume this Lease for the purpose of assigning the same or otherwise,
such election and assignment may only be made if all of the terms and conditions
of Sections 20.B and 20.D hereof are satisfied. The Tenant acknowledges that it
is essential to the ability of Landlord to continue servicing the mortgage on
the Building that a decision on whether to assume or reject this Lease be made
promptly. Under these circumstances, Tenant agrees that should Tenant, as
debtor-in-possession ("Debtor-in-Possession") or any Trustee appointed for
Tenant, fail to elect to assume this Lease within sixty (60) days after the
filing of the petition under the Bankruptcy Code ("Tenant's Petition"), this
Lease shall be deemed to have been rejected. Tenant further knowingly and
voluntarily waives any right to seek additional time to affirm or reject the
Lease and acknowledges that there is no cause to seek such extension. If Tenant,
as Debtor-in-Possession, or the Trustee abandons the Premises, the same shall be
deemed a rejection of the Lease. Landlord shall be entitled to at least thirty
(30) days prior written notice from Tenant, as Debtor-in-Possession, or its
Trustee of any intention to abandon the Premises. Landlord shall thereupon be
immediately entitled to possession of the Premises without further obligation to
Tenant or the Trustee, and this Lease shall be cancelled, but Landlord's right
to be compensated for damages in such liquidation proceeding shall survive.

     B. No election by the Trustee or Debtor-in-Possession to assume this Lease,
whether under Chapter 7, 11 or 13, shall be effective unless each of the
following conditions, which Landlord and Tenant acknowledge are commercially
reasonable in the context of a bankruptcy proceeding of Tenant, have been
satisfied, and Landlord has so acknowledged in writing:

          (1)  The Trustee or the Debtor-in-Possession has cured, or has
               provided Landlord adequate assurance (as defined below) that:

               (a)  Within ten (10) days from the date of such assumption the
                    Trustee will cure all monetary defaults under this Lease;
                    and

               (b)  Within thirty (30) days from the date of such assumption the
                    Trustee will cure all non-monetary defaults under this
                    Lease.

          (2)  The Trustee or the Debtor-in-Possession has compensated, or has
               provided to Landlord adequate assurance that within ten (10) days
               from the date of assumption Landlord will be compensated, for any
               pecuniary loss incurred by Landlord arising from the default of
               Tenant, the Trustee, or the Debtor-in-Possession as recited in
               Landlord's written statement of pecuniary loss sent to the
               Trustee or Debtor-in-Possession.

          (3)  The Trustee or the Debtor-in-Possession has provided Landlord
               with adequate assurance of the future performance (as defined
               below) of each of Tenant's the Trustee's or
               Debtor-in-Possession's obligations under this Lease, provided,
               however, that:

               (a)  The Trustee or Debtor-in-Possession shall also deposit with
                    Landlord, as security for the timely payment of rent, an
                    amount equal to three (3) months Base Rent (as adjusted
                    pursuant to Section 20.B.(3)(c) below) and other monetary
                    charges accruing under this Lease; and

                                      -17-
<PAGE>

               (b)  If not otherwise required by the terms of this Lease, the
                    Trustee or Debtor-in-Possession shall also pay in advance
                    one-twelfth (1/12th) of Tenant's annual obligations under
                    this Lease for Operating Costs, Taxes, insurance and similar
                    charges.

               (c)  From and after the date of the assumption of this Lease, the
                    Trustee or Debtor-in-Possession shall pay as minimum rent
                    an amount equal to the sum of the minimum rent otherwise
                    payable hereunder, within the five (5) year period prior to
                    the date of Tenant's Petition, which amount shall be payable
                    in advance in equal monthly installments.

               (d)  The obligations imposed upon the Trustee or
                    Debtor-in-Possession shall continue with respect to Tenant
                    or any assignee of this Lease after the completion of
                    bankruptcy proceedings.

          (4)  The assumption of the Lease will not breach any provision in any
               other lease, mortgage, financing agreement or other agreement by
               which Landlord is bound relating to the Property.

          (5)  The Tenant as Debtor-in-Possession or its Trustee shall provide
               the Landlord at least forty-five (45) days' prior written notice
               of any proceeding concerning the assumption of this Lease.

          (6)  For purposes of this Section 20.B, Landlord and Tenant
               acknowledge that, in the context of a bankruptcy proceeding of
               Tenant, at a minimum "adequate assurance" shall mean:

               (1)  The Trustee or the Debtor-in-Possession has and will
                    continue to have sufficient unencumbered assets after the
                    payment of all secured obligations and administrative
                    expenses to assure Landlord that the Trustee or
                    Debtor-in-Possession will have sufficient funds to fulfill
                    the obligations of Tenant under this Lease.

               (2)  The Bankruptcy Court shall have entered an order segregating
                    sufficient cash payable to Landlord, and/or the Trustee or
                    Debtor-in-Possession shall have granted a valid and
                    perfected first lien and security interest and/or mortgage
                    in property of Tenant, the Trustee or Debtor-in-Possession,
                    acceptable as to value and kind to Landlord, to secure to
                    Landlord the obligation of the Trustee or
                    Debtor-in-Possession, to cure the monetary and/or
                    non-monetary defaults under this Lease within the time
                    periods set forth above.

     C. In the event that this Lease is assumed by a Trustee appointed for
Tenant or by Tenant as Debtor-in-Possession, under the provisions of Section
20.B hereof, and thereafter Tenant is liquidated or files a subsequent Tenant's
Petition for reorganization or adjustment of debts under Chapter 11 or 13 of the
Bankruptcy Code, then, and in either of such events, Landlord may, at its
option, terminate this Lease and all rights of Tenant hereunder, by giving
Tenant written notice of its election to so terminate, within thirty (30) days
after the occurrence of either of such events.

     D. If the Trustee or Debtor-in-Possession has assumed this Lease pursuant
to the terms and provisions of 20.A and 20.B hereof, for the purpose of
assigning (or elects to assign) Tenant's interest under this Lease or the estate
created thereby, to any other person, such interest or estate may be so assigned
only if Landlord shall acknowledge in writing that the intended assignee has
provided adequate assurance as defined in this Section 20.D of future
performance of all of the terms, covenants and conditions of this Lease to be
performed by Tenant.

                                      -18-
<PAGE>

          For purposes of this Section 20.D, Landlord and Tenant acknowledge
that, in the contest of a bankruptcy proceeding of Tenant, at a minimum
"adequate assurance of future performance" shall mean that each of the following
conditions have been satisfied, and Landlord has so acknowledged in writing:

          (a)  The assignee has submitted a current financial statement audited
               by a certified public accountant which shows a net worth and
               working capital in amounts determined to be sufficient by
               Landlord to assure the future performance by such assignee of
               Tenant's obligations under this Lease;

          (b)  The assignee, if requested by Landlord, shall have obtained
               guarantees in form and substance satisfactory to Landlord from
               one or more persons who satisfy Landlord's standards of
               creditworthiness; and

          (c)  The Landlord has obtained all consents or waivers from any third
               party required under any lease, mortgage, financing arrangement
               or other agreement by which Landlord is bound to permit Landlord
               to consent to such assignment.

     E. When, pursuant to the Bankruptcy Code, the Trustee or
Debtor-in-Possession shall be obligated to pay reasonable use and occupancy
charges for the use of the Premises or any portion thereof, such charges shall
not be less than the minimum rent as defined in this Lease and other monetary
obligations of Tenant for the payment of Operating Costs, Taxes, insurance and
similar charges.

     F. Neither Tenant's interest in this Lease, nor any lesser interest of
Tenant herein, nor any estate of Tenant hereby created, shall pass to any
trustee, receiver, assignee for the benefit of creditors, or any other person or
entity, or otherwise by operation of law, unless Landlord shall consent to such
transfer in writing. No acceptance by Landlord of rent or any other payments
from any such trustee, receiver, assignee, person or other entity shall be
deemed to have waived, nor shall it waive the need to obtain Landlord's consent,
or Landlord's right to terminate this Lease for any transfer of Tenant's
interest under this Lease without such consent.

     G. In the event the estate of Tenant created hereby shall be taken in
execution or by the process of law, or if Tenant or any guarantor of Tenant's
obligations shall be adjudicated insolvent pursuant to the provisions of any
present or future insolvency law under state law, or if any proceedings are
filed by or against such guarantor under the Bankruptcy Code, or any similar
provisions of any future federal bankruptcy law, or if a custodian receiver or
Trustee of the property of Tenant or such guarantor shall be appointed under
state law by reason of Tenant's or such guarantor's insolvency or inability to
pay its debts as they become due or otherwise, or if any assignment shall be
made of Tenant's or such guarantor's property for the benefit of creditors under
state law; then and in any such event Landlord may, at its option, terminate
this Lease and all rights of Tenant hereunder by giving Tenant written notice of
the election to so terminate within thirty (30) days after the occurrence of
such event.

                                       21.

                                     DEFAULT

     A.   If any of the following events of default shall occur, to wit;

          (i)  Tenant defaults for more than five (5) days after written notice
               of default after the due date therefor in the payment of rent
               (whether Base Rent or additional rent) or any other sum required
               to be paid hereunder, or any part thereof, or

          (ii) Tenant defaults in the prompt and full performance of any other
               (i.e.

                                      -19-
<PAGE>

               other than payment of rent or any other sum) covenant, agreement
               or condition of this Lease and such other default shall continue
               for a period of thirty (30) days after written notice thereof
               from Landlord to Tenant (unless such other default involves a
               hazardous condition, in which event it shall be cured forthwith),
               provided however in the event such default cannot be cured within
               a period of thirty (30) days and Tenant is diligently attempting
               to cure such default, the time period to cure same shall be
               reasonably extended, or

         (iii) The leasehold interest of Tenant be levied upon under execution
               or be attached by process of law, or if Tenant abandons the
               Premises, or

          (iv) Adjudication of Bankruptcy or insolvency of Tenant, then in any
               such event, Landlord, besides other rights or remedies, it may
               have, shall have the immediate right of re-entry and may remove
               all persons and property from the Premises; such Property may be
               removed and stored in any other place in the Building in which
               the Premises are situated, or in any other place, for the account
               of and at the expense and at the risk of Tenant.

     B. Tenant hereby waives all claims for damages which may be caused by the
re-entry of Landlord and taking possession of the Premises or removing or
storing the furniture and property as herein provided, and will save Landlord
harmless from any loss, costs, or damages occasioned Landlord thereby, and no
such re-entry shall be considered or construed to be a forcible entry.

     C. Should Landlord elect to re-enter, as herein provided, or should it take
possession pursuant to legal proceedings or pursuant to any notice provided for
by law; it may either terminate this Lease or it may from time to time, without
terminating this Lease, re-let the Premises or any part thereof for such terms
and at such rental or rentals and upon such other terms and conditions as
Landlord in its sole discretion may deem advisable, with the right to make
alterations and repairs to the Premises.

     D. Landlord may elect to apply rentals received by it (i) to the payment of
any indebtedness, other than rent, due hereunder from Tenant to Landlord; (ii)
to the payment of any reasonable cost of such re-letting including but not
limited to any broker's commissions or fees in connection therewith; (iii) to
the payment of the cost of any reasonable alterations and repairs to the
Premises; (iv) to the payment of rent due and unpaid hereunder; and the residue,
if any, shall be held by Landlord and applied in payment of future rent as the
same may become due and payable hereunder. Should such rentals received from
such re-letting after application by Landlord to the payments described in
foregoing clauses (i) through (iv) during any month be less than that agreed to
be paid during that month by Tenant hereunder, then Tenant shall pay such
deficiency to Landlord. Such deficiency shall be calculated and paid monthly on
demand by Landlord.

     E. In lieu of electing to receive and apply rentals as provided in the
immediately preceding paragraph, Landlord may elect to receive from Tenant as
and for Landlord's liquidated damages for Tenant's default, an amount equal to
the present value of the entire amount of Base Rent provided for in this Lease
for the remainder of the Term, less fair market rental value thereof, which
amount shall be forthwith due and payable by Tenant upon its being advised of
such election by Landlord.

     F. No such re-entry or taking possession of the Premises by Landlord shall
be construed as an election on its part to terminate this Lease unless a written
notice of same is given to Tenant or unless the termination thereof be decreed
by a court of competent Jurisdiction. Notwithstanding any such re-letting
without termination, Landlord may at any time thereafter elect to terminate this
Lease for such previous breach.

     G. Nothing herein contained shall limit or prejudice the right of Landlord
to provide for and obtain as damages by reason of any such termination of this
Lease or of

                                      -20-
<PAGE>

possession an amount equal to the maximum allowed by any statute or
rule of law in effect at the time when such termination takes place (other than
consequential or special damages), whether or not such amount be greater, equal
to or less than the amounts of damages which Landlord may elect to receive as
set forth above. Notwithstanding anything to the contrary herein contained or
any other rights exercised by Landlord hereunder, upon the occurrence of an
event of a monetary or material default by Tenant under the terms of this Lease,
rent which otherwise would be due or would have been due except for any
abatement provided for in this Lease shall be immediately due and payable.
Landlord agrees to use reasonable efforts to mitigate its damages in the event
of any default by Tenant.

                                       22.

                              RULES AND REGULATIONS

     The rules and regulations attached hereto and marked Appendix "B", as well
as such reasonable rules and regulations as may be hereafter adopted by Landlord
for the safety, care and cleanliness of the Premises and the preservation of
good order thereon, are hereby expressly made a part hereof, and Tenant agrees
to obey all such rules and regulations. The violation of any such rules and
regulations by Tenant shall be deemed a default under this Lease by Tenant,
affording Landlord all those remedies set out in the Lease. Landlord shall not
be responsible to Tenant for the non-performance by any other tenant or occupant
of the Building or any of said rules and regulations. Landlord agrees all rules
and regulations shall be uniformly enforced.

                                       23.

                              NON REAL ESTATE TAXES

     During the term hereof, Tenant shall pay prior to delinquency all taxes
assessed against and levied upon fixtures, furnishings, equipment and all other
personal property of Tenant contained in the Premises, and Tenant shall cause
said fixtures, furnishing, equipment and other personal property to be assessed
and billed separately from the real property of Landlord. In the event any or
all of the Tenant's fixtures, furnishings, equipment and other personal property
shall be assessed and taxed with the Landlord's real property, the Tenant shall
pay to Landlord its share of such taxes within ten (10) days after delivery to
Tenant by Landlord of a statement in writing setting forth the amount of such
taxes applicable to the Tenant's property.

                                       24.

                                 EMINENT DOMAIN

     If the Building, or a substantial part thereof or a substantial part of the
Premises, shall be lawfully taken or condemned or conveyed in lieu thereof, (or
conveyed under threat of such taking or condemnation), for any public or
quasi-public use or purpose, the term of this Lease shall end upon and not
before the date of the taking of possession by the condemning authority and
without apportionment of the award. Tenant hereby assigns to Landlord Tenant's
interest, if any, in such award and specifically agrees that any such award
shall be the entire property of Landlord in which Tenant shall not be entitled
to share. Tenant further waives any right to challenge the right of the
condemning authority to proceed with such taking. Current rent shall be
apportioned as of the date of such termination. If any part of the Building
other than the Premises or not constituting a substantial part of the Premises,
shall be so taken or condemned (or conveyed under threat of such taking or
condemnation), or if the grade of any street adjacent to the Building is changed
by any competent authority and such taking or change of grade makes it necessary
or desirable to substantially remodel or restore the Building, Landlord shall
have the right to cancel this Lease upon not less than ninety (90) days notice
prior to the date of cancellation designated in the notice. No money or

                                      -21-
<PAGE>

other consideration shall be payable by Landlord to Tenant for the right of
cancellation, and Tenant shall have no right to share in any condemnation
award or in any judgment for damages or in any proceeds of any sale made
under any threat of condemnation or taking. Tenant shall have the right to
separately pursue its own award for relocation expenses in the event of such

                                  SUBORDINATION

     A. Landlord has heretofore and may hereafter from time to time execute
and deliver mortgages or trust deeds in the nature of a mortgage, both
referred to herein as "Mortgages" against the Land and Building, or any
interest therein. If requested by the mortgagee or trustee under any
Mortgage, Tenant will either (a) subordinate its interest in this Lease to
said Mortgages, and to any and all advances made thereunder and to the
interest thereon, and to all renewals, replacements, modifications and
extensions thereof, or (b) make Tenant's interest in this Lease inferior
thereto; and Tenant will promptly execute and deliver such agreement or
agreements as may be reasonably required by such mortgage or trustee under
any Mortgage, provided however that any such subordination shall provide that
so long as Tenant is not in default hereunder, its tenancy shall not be
disturbed. Landlord further agrees to obtain written assurance of such
non-disturbance from any present mortgagee.

     B. It is further agreed that (i) if any Mortgage shall be foreclosed (a)
the liability of the mortgagee or trustee thereunder or purchaser at such
foreclosure sale or the liability of a subsequent owner designated as
Landlord under this Lease shall exist only so long as such trustee,
mortgagee, purchaser or owner is the owner of the Building and such liability
shall not continue or survive after further transfer of ownership; and (b)
upon request of the mortgagee or trustee, Tenant will attorn, as Tenant under
this Lease, to the purchaser at any foreclosure sale under any Mortgage, and
Tenant will execute such instruments as may be necessary or appropriate to
evidence such attornment; and (ii) this Lease may not be modified or amended
so as to reduce the rent or shorten the term provided hereunder, or so as to
adversely affect in any other respect to any material extent the rights of
the Landlord, nor shall this Lease be canceled or surrendered without the
prior written consent, in each instance of the mortgagee or trustee under any
Mortgage. It is understood that Tenant's tenancy shall not be disturbed so
long as Tenant is not in default under this Lease.

     C. No mortgagee and no person acquiring title to the premises by reason
of foreclosure of any Mortgage or by conveyance in lieu of foreclosure shall
have any obligation or liability to Tenant on account of any security deposit
unless such mortgagee or title holder shall receive such security deposit in
cash.

                                       26.

                                     WAIVER

     The waiver of Landlord of any breach of any term, covenant or condition
herein contained shall not be deemed to be a waiver of such term, covenant or
condition or any subsequent breach of the same or any other term, covenant,
or condition herein contained. The acceptance of rent hereunder shall not be
construed to be a waiver of any breach by Tenant of any term, covenant or
condition of this Lease. It is understood and agreed that the remedies herein
given to Landlord shall be cumulative, and the exercise of any one remedy by
Landlord shall not be to the exclusion of any other remedy. It is also agreed
that after the service of notice or the commencement of a suit or judgment
for possession of the Premises, Landlord may collect and receive any monies
due, and the payment of said monies shall not waive or affect said notice,
suit or judgment.

                                       27.

                              INABILITY TO PERFORM

     This Lease and the obligation of Tenant to pay rent hereunder and
perform all of the covenants and agreements hereunder on part of Tenant to be
performed shall not be affected, impaired or excused, nor shall Landlord at
any time be deemed to be in default hereunder because Landlord is unable to
fulfill any of its obligations under this Lease or to supply or is delayed in
supplying any service expressly or by implication to be supplied or is unable
to make, or is delayed in making any Tenant improvement, repair, additions,
alterations, or decorations or is unable to supply or is delayed in supplying
any equipment or fixtures if Landlord is prevented or delayed from so doing
by reason of acts or omissions of Tenant, strike or labor troubles or any
outside cause whatsoever beyond the reasonable control of Landlord, including
but not limited to riots and civil disturbances or energy shortages or
governmental preemption in connection with a national emergency or by reason
of any rule, order, or regulation of any department or subdivision thereof of
any government agency or by reason of the conditions of supply and demand
which have been or are affected by war or other emergency. Tenant shall at no
time be deemed in default hereunder because Tenant is unable to fulfill any
of its non-monetary obligations hereunder by reason of any outside cause
whatsoever beyond the reasonable control of Tenant.

                                       28.

                                   SUBROGATION

     The parties hereto agree to use good faith efforts to have any and all
fire, extended coverage or any and all material damage insurance which may be
carried endorsed with a subrogation clause substantially as follows: "This
insurance shall not be invalidated should the insured waive in writing prior
to a loss any or all right of recovery against any party for loss occurring
to the property described herein"; and each party hereto waives all claims
for recovery from the other party for any loss or damage (whether or not such
loss or damage is caused by negligence of the other party and notwithstanding
any provision or provisions contained in this Lease to the contrary) to any
of its property insured under valid and collectible insurance policies to the
extent of any recovery collectible under such insurance, subject to the
limitation that this waiver shall apply only when it is permitted by the
applicable policy of insurance.

                                       29.

                                SALE BY LANDLORD

     In the event of a sale or conveyance by Landlord of the Building
containing the Premises, the same shall operate to release Landlord from any
future liability upon any of the covenants or conditions, expressed or
implied, herein contained in favor of Tenant, and in such event Tenant agrees
to look solely to the responsibility of the successor in interest of Landlord
in and to this Lease for such future obligation. If any security deposit has
been made by Tenant hereunder, Landlord shall transfer such security deposit
to such successor in interest of Landlord and thereupon Landlord shall be
released from any further obligations hereunder. This Lease shall not be
affected by any such sale, and the Tenant agrees to attorn to the purchaser
or assignee.

                                       30.

                          RIGHTS OF LANDLORD TO PERFORM

     All covenants and agreements to be performed by Tenant under any of the
terms of this Lease shall be performed by Tenant at Tenant's sole cost and
expense and without any

                                      -23-

<PAGE>

abatement of rent. If Tenant shall fail to pay any sum of money, other than
rent, required to be paid it hereunder, or shall fail to perform any other
act on its part to be performed hereunder, and such failure shall continue
for ten (10) days after notice thereof by Landlord, Landlord may, but shall
not be obligated so to do, and without waiving or release Tenant from any
obligations of Tenant, make any such payment or perform any such other act on
Tenant's part to be made or performed as in this Lease provided. All sums so
paid by Landlord and all necessary incidental costs together with interest
thereon at the rate heretofore set forth with respect to late payments of
rent, computed from the date of such payment by Landlord shall be payable to
Landlord on demand and the Landlord shall have (in addition to any other
right or remedy of Landlord) the same rights and remedies in the event of the
non-payment thereof by Tenant as in the case of default by Tenant in the
payment of rent.

                                       31.

                                 ATTORNEYS' FEES

     In the event of any litigation between Tenant and Landlord to enforce
any provision of this Lease, or any right of either party hereto, the
unsuccessful party of such litigation, shall pay to the prevailing party all
costs and expenses, including reasonable attorneys' fees, incurred therein.
Moreover, if either party, without fault is made a party to any litigation
instituted by or against the other party, the other party shall indemnify
such party without fault against and save it harmless from all costs and
expenses, including reasonable attorneys' fees incurred by it in connection
therewith.

                                       32.

                              ESTOPPEL CERTIFICATE

     Either party shall at any time and from time to time upon not less than
ten (10) days' prior written notice from the other and not more than twice
annually, execute, acknowledge and deliver to the requesting party a
statement in writing certifying that this Lease is unmodified and in full
force and effect (or if modified, stating the nature of the modification and
certifying that this Lease, as so modified, is in full force and effect) and
the dates to which the rental and other charges are paid and acknowledging
that there are not, to such certifying party's knowledge, any uncured
defaults on the part of the other party hereunder or specifying such defaults
if any are claimed, as well as any other reasonable information requested by
Landlord. In the case of a statement made by Tenant, it is expressly
understood and agreed that 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 Premises are a part. Tenant's failure to deliver such
statement within such time shall be conclusive upon Tenant that this Lease is
in full force and effect, without modification except as may be represented
by Landlord, that there are no uncured defaults in Landlord's performance and
that not more than two (2) months' rental has been paid in advance.

                                       33.

                                   PREPARATION

     Landlord agrees as provided in Appendix "C" to cause the Premises to be
completed in accordance with the plans, specification and agreements approved
by both parties on the terms, conditions, and provision as provided in the
plans attached hereto in Appendix "C" which is attached hereto and made a
part of this Lease.

                                     NOTICE

     Any notice from Landlord to Tenant or from Tenant to Landlord may be served
personally, by mail, by overnight delivery, by affixing a copy on any door
leading into the Premises or by facsimile transmission. If served by mail,
notice shall be deemed served on the second day after mailing by registered or
certified mail, addressed to Tenant at the Premises or to Landlord at the place
from time to time established for the payment of rent and a copy thereof shall
until further notice, be served personally or by registered or certified mail to
Landlord at the address shown for service of notice in the Lease Schedule. In
the event of a release or threatened release of pollutants or contaminants to
the environment resulting from Tenant's activities at the site or in the event
any claim, demand, action or notice is made against the Tenant regarding
Tenant's failure or alleged failure to comply with any local, state and federal
environmental rules, regulations, statutes and laws, the Tenant shall
immediately notify the Landlord in writing and shall give to Landlord copies of
any written claims, demands or actions, or notices so made.

                                       35.

                                 RIGHTS RESERVED

     Landlord reserves the following rights, exercisable without notice and
without liability to Tenant for damage or injury to property, person or business
and without effecting an eviction, constructive or actual or disturbance of
Tenant's use of possession or giving rise to any claim for set-off or abatement
of rent:

     (a)  Except as otherwise herein provided, to install, affix and maintain
          any and all signs on the interior or exterior of the Building;

     (b)  To designate and approve, prior to installation, all types of window
          shades, blinds, drapes, awnings, window ventilators and other similar
          equipment, and to control all interior or exterior lighting of the
          Building;

     (c)  To designate, restrict and control all sources from which Tenant may
          obtain sign painting and lettering, food and beverages or other
          services on the Premises, and in general to designate, limit, restrict
          and control any service in or to the Building and its Tenant, provided
          such services as are designated by Landlord are reasonably competitive
          as to the rates charged thereby, and further provided that such
          designation, restrictions, or controls do not prohibit Tenant's
          operations in accordance with the terms of this Lease. No vending or
          dispensing machines of any kind shall be placed in or about the
          Premises without the prior written consent of Landlord, which consent
          shall not be unreasonably withheld. Notwithstanding the foregoing, it
          is understood that Tenant shall have the right to operate beverage
          machines, microwave ovens, and refrigerators for the convenience of
          its employees and invitees;

     (d)  To retain at all times, and to use in appropriate instances, keys
          and/or keycards, to all doors within and into the Premises. No locks

     (e)  To decorate or to make repairs, alterations, additions or
          improvements, whether structural or otherwise, in and about the

          Premises, and during the continuance of said work to temporarily close
          doors, entryways, and public spaces in the Building and to interrupt
          or temporarily suspend Building services and facilities, provided that
          Tenant is not prevented from access to the Premises, or are its
          operations materially interfered with;

                                      -25-
<PAGE>

     (f)  To prescribe the location and style of the suite number and
          identification sign or lettering for the Premises occupied by Tenant;

     (g)  Subject to any restrictions on Landlord's access provided elsewhere
          herein to enter the Premises at reasonable hours for reasonable
          purposes upon reasonable notice except in cases of emergency,

          other service to be provided to Tenant hereunder;

          provisions of the Lease. Landlord shall not be liable except for the
          willful or negligent act or omission of Landlord in damages for any
          error with respect to admission to or eviction or exclusion from the
          Building of any person. In case of fire, invasion, insurrection, mob,
          riot, civil disorder, public excitement or other commotion, or threat
          thereof, Landlord reserves the right to limit or prevent access to the
          Building during the continuance of the same or otherwise take such
          action or preventive measures deemed necessary by Landlord for the
          safety of the Tenants or other occupants of the Building or the
          protection of the Building and the property in the Building. Tenant
          agrees to cooperate in any reasonable safety program developed by
          Landlord;

     (i)  To control and prevent access to common areas and other non-general
          public areas including any loading docks, service elevators, or roof;

     (j)  To have and retain a paramount title to the Premises free and clear of
          any act of Tenant;

     (k)  To grant to anyone the exclusive right to conduct any business or
          render any services in the Building, which do not interfere with
          Tenant's use of the Premises;

          Landlord shall direct in writing. Movements of Tenant's property into
          or out of the Building and within the Building are entirely at the
          risk and responsibility of Tenant and Landlord reserves the right to
          require permits before allowing any such property to be moved into or
          out of the building.

                                       36.

                               REAL ESTATE BROKER

     Tenant represents that Tenant has dealt directly with and only with the
brokers set forth in the Lease Schedule as brokers in connection with this Lease
and agrees to indemnify and hold Landlord harmless from all claims or demands of
any other broker or brokers for any commission alleged to be due such broker or
brokers in connection with its participating in the negotiation with Tenant of
this Lease.

                                       37.

                            MISCELLANEOUS PROVISIONS

          provisions.

<PAGE>

          constitute a reservation or offer or option for lease, and it is not
          effective as a lease or otherwise so as to incur the least
          inconvenience to Tenant. Tenant acknowledges and agrees with Landlord
          that, except as may be specifically set forth elsewhere in this Lease,
          neither Landlord, nor any employee of Landlord, nor other party
          claiming to act on Landlord's behalf, has made any representations,
          warranties, estimations, or promises of any kind or nature whatsoever
          relating to the physical condition of the Building in which the
          Premises are located, or the land under the Building, including by way
          of example only, the fitness of the Premises for Tenant's intended use
          or the actual dimensions of the Premises or Building; and

     C.   The invalidity or unenforceability of any provision hereof shall not
          affect or impair any other provisions.

     D.   This Lease shall be governed by and construed pursuant to the laws of
          the Jurisdiction on which the property is located.

     E.   Tenant agrees to provide to Landlord, upon request, a current
          financial statement of Tenant certified by an authorized
          representative of Tenant to be true and correct, and further agrees to
          provide any other financial information reasonably requested by
          Landlord.

     F.   All rights and remedies of Landlord under this Lease, or that may be
          provided by law, may be exercised by Landlord in its own name
          individually, or in its name by its Management Agent, and all legal
          proceedings for the enforcement of any such rights or remedies,
          including distress for rent, forcible detainer, and any other legal or
          equitable proceedings, may be commenced and prosecuted to final
          judgment and execution by Landlord in its own name individually or in
          its name or by its agent. Tenant conclusively agrees that Landlord has
          full power and authority to execute this Lease and to make and perform
          the agreements herein contained and Tenant expressly stipulates that
          any rights or remedies available to Landlord either by the provision
          of this Lease or otherwise may be enforced by Landlord in its own name
          individually or in its name by agent or principal.

     G.   All of the covenants and conditions of this Lease shall survive
          termination of the Lease.

     H.   The marginal headings and titles to the paragraphs of this Lease are
          not a part of this Lease and shall have no effect upon the
          construction or interpretation of any part hereof.

     I.   Any and all Exhibits or Appendices attached hereto are expressly made
          a part of this Lease.

     J.   Upon termination of the Lease or upon Tenant's abandonment of the
          leasehold, the Tenant shall, at its sole expense, remove any equipment
          which may cause contamination of the property, and shall clean up any
          existing contamination in compliance with all applicable local, state
          and federal environmental rules, regulations, statutes and laws or in
          accordance with orders of any governmental regulatory authority.

     K.   This is a commercial lease and has been entered into by both parties
          in reliance upon the economic and legal bargains contained herein, and
          both parties agree and represent each to the other that they have had
          the opportunity to obtain counsel of their own choice to represent
          them in the negotiation and execution of this Lease, whether or not
          either or both have elected to avail themselves of such opportunity.
          This Lease shall be interpreted and construed in a fair and impartial
          manner without regard to such factors as the party which prepared the
          instrument, the relative bargaining powers of the parties or the
          domicile of

                                      -27-

     L.   WAIVER OF RIGHT TO TRIAL BY JURY. Landlord and Tenant hereby waive any
          right to a trial by jury in any action or proceeding based upon, or
          related to, the subject matter of this Lease. This waiver is
          knowingly, intentionally, and voluntarily made by each of parties
          hereto and each party acknowledges to the other that neither the other
          party nor any person acting on its respective behalf has made any
          representations to induce this waiver of trial by jury or in any way
          to modify or nullify its effect. The parties acknowledge that they
          have read and understand the meaning and ramifications of this waiver
          provision and have elected same of their own free will.

     M.   Landlord hereby covenants that so long as Tenant is not in default
          under the terms and provisions of this Lease, Tenant shall be entitled
          to quiet enjoyment of the Premises.

     N.   This Lease does not grant any rights to light or air over or about the
          real property of Landlord. Except to the extent specifically otherwise
          herein provided, Landlord specifically excepts and reserves to itself
          the use of any roofs, the exterior portions of the Building, all
          rights to and the land and improvements below the improved floor level
          of the Building, to the improvements and air rights above the Building
          and to the improvements and air rights located outside the demising
          walls of the Building and to such areas within the Building required
          for installation of utility lines and other installations required to
          serve any occupants of the Building and to maintain and repair same,
          and no rights with respect thereto are conferred upon Tenant, unless
          otherwise specifically provided herein.

     O.   In accordance with applicable codes, Landlord shall provide 4.4
          parking spaces per 1,000 square feet of rentable area of the Building,
          which Tenant shall be entitled to use on a non-exclusive basis.

                                      38.

                                   AUTHORITY

     Tenant represents and warrants that this Lease has been duly authorized,
executed and delivered by and on behalf of the Tenant and constitutes the valid
and binding agreement of the Tenant in accordance with the terms hereof.

                                       39.

                             SUCCESSORS AND ASSIGNS

     The covenants and conditions herein contained shall apply to and bind the
respective heirs, successors, Executors, administrators, and assigns of the
parties hereto. The terms "Landlord" and "Tenant" shall include the successors
and assigns of either such party, whether immediate or remote.

                                       40.

                               TERMINATION OPTIONS

     So long as Tenant is not in default, Tenant shall have the right to elect
to terminate the Lease effective February 28, 2005, or effective February 28,

                                 RENEWAL OPTIONS

     So long as Tenant is not in default, Tenant shall have two (2) options to
extend the Term of this Lease for two (2), five (5) year periods upon the same
terms and conditions contained herein except for rental. Said options shall be
exercised in writing not less than twelve (12) months prior to the expiration of
the initial term, or the first extended term as the case may be. In the event of
exercise of either or both of said options, Base Rent for each extended period
shall be equal to ninety-five (95%) percent of the then prevailing market rate
and terms, including but not limited to escalations, commissions, tenant
improvements, allowances and concessions ("PMR"). In the event Landlord and
Tenant are unable to agree on PMR within thirty (30) days of Tenant's exercise
of either option, each party shall select a Qualified Broker, as hereinafter
defined, which Qualified Broker shall select a third Qualified Broker. The
majority of such three Qualified Brokers shall determine the PMR within thirty
(30) days of the selection of the third Qualified Broker, and Tenant shall have
ten (10) days from receipt of such determination in writing to withdraw its
election, or to agree to lease based upon the PMR as so determined. A Qualified
Broker shall be licensed broker, with not less than ten (10) years brokerage
experience in the general vicinity of the Property with comparable properties.
Failure to exercise the first such option shall render the second such option
null and void.

                                       42.

                              RIGHT OF FIRST OFFER

     So long as Tenant is not in default, Tenant shall have a right of first
offer on not less than 12,000 rentable square feet of the first floor of the
Building on the following terms and conditions. At such time as Landlord has
either: (a) issued its initial proposal for the leasing of such space; or (b)
has prepared a space plan for such space, then Landlord shall notify Tenant of
the terms and conditions under which Landlord is willing to lease such space to
a third party. Tenant shall have a period of ten (10) calendar days from receipt
of such notice in which to advise Landlord in writing that it elects to lease
all of such space on the terms and conditions set forth in Landlord's notice for
a term which shall be co-terminus with the term hereunder, but shall in no event
be less than a period of five (5) years. If Tenant does not so advise Landlord
in writing of its exercise of such right, Landlord shall be entitled to enter
into a lease of such space to third party tenants on materially the same terms
and conditions contained in the notice given to Tenant. In the event Landlord
does not enter into a lease on such terms and conditions with third parties
within ninety (90) days from the date of said notice, then Tenant's rights
hereunder shall be deemed reinstated.

                                       43.

          CELLULAR, RADIO, MICROWAVE AND OTHER ELECTRONIC TRANSMISSION

     Tenant may use the Property for any lawful activity in connection with the
provision of mobile communication, including without limitation, the
transmission and the reception of radio, microwave, or other electronic
communication signals on various frequencies of service. Landlord agrees to
cooperate with Tenant in making applications for and obtaining all licenses,
permits and any and all other necessary approvals that may be required for this
aspect of Tenant's intended use of the Property, all of which shall be at
Tenant's sole cost and expense. At all times during the term of the Lease,
Tenant will be responsible for obtaining and maintaining any licenses or
approvals that may be required from any governmental body of competent
jurisdiction for this aspect of its intended use of the Property. Failure to
obtain any such required licenses or approvals shall not invalidate any portion
of the Lease other than those provision contained within this Section 43. If
requested by Landlord, Tenant shall provide copies of all such licenses or
approvals, including copies of any forms used in making

                                      -29-

application for same.

     After approval of Tenant's specific plans by Landlord, which approval shall
not be unreasonably withheld or delayed, Tenant, at its sole cost and expense,
shall have the right to erect, maintain and operate radio communications
facilities, including radio transmitting and receiving antennas, towers,
microwave dishes and supporting structures thereto (the Tenant's facilities). In
connection therewith and after Landlord's approval of Tenant's specific plans
and under Landlord's reasonable direction, Tenant shall have the right to
prepare, maintain and alter the Property for Tenant's business operations and to
install transmission lines connecting to Tenant's facilities to the Building.

in a workman like manner and any damage to the Building, Premises or Property
done by Tenant and Tenant's suppliers and/or subcontractors shall be reported to
Landlord and shall be repaired by Tenant at its sole cost and expense. Any

state or other applicable ordinances and/or codes and shall not interfere with
the reception of television, radio or other electronic signals or the operation
of any equipment used on the Property by any other tenant or other occupants, or
by owners or tenants of surrounding properties and/or building. Title to the
Tenant facilities shall be held by Tenant at all times. Tenant facilities shall
remain Tenant's personal property and are not fixtures. Tenant has the right to
remove all Tenant facilities at is sole cost and expense on or before expiration
of the term, provided that Tenant shall be responsible for repairing any damage
to the Building or the Property resulting from said removal to the reasonable
satisfaction of Landlord. Landlord agrees it will not allow other tenants to use
the roof of the Building in such a manner as may interfere with Tenant's
operations.

     TENANT shall at all times operate Tenant facilities in a manner that
Tenant's transmission will not cause interference with television, radio or
other electronic signals to Landlord, to other tenants of the Building or
Property, or to owners, tenants or occupants of surrounding properties lawful
and in compliance with all regulations or requirements of Federal Communications
Commission or, any other governmental agency of competent jurisdiction. Tenant
shall hold Landlord and Landlord's agents harmless from any and all liabilities
arising out of the installation, maintenance, or operation of the Tenant
facilities whether such liabilities arise (i) from interference with radio,
television and other electronic reception within the Building; (ii) from
interference with the business operations of Landlord's other tenants within the
Building; (iii) from interference with the business operation or radio,
television or other electronic reception in buildings surrounding or adjoining
the Property; (iv) from tower or equipment breakage, collapse or failure; (v) or
from any other cause directly or indirectly resulting from Tenant's use,
maintenance, installation and/or operation of the Tenant facilities.

day and year first above written.

                                    GUARANTY

     In order to induce Landlord to execute the foregoing Lease, the undersigned
does hereby absolutely and unconditionally guarantee the full performance and
observance of all of the covenants, conditions, and agreements provided to be
performed and observed by Tenant in said Lease, including, without limitation,
the prompt payment of the Base Rent and Rent Adjustments and all other amounts
provided in said Lease to be paid by Tenant.

     The undersigned hereby waives notice of non-payment, non-performance or
non-observance and all other notices and all proof or demands.

     Further, the undersigned expressly agrees that its obligations hereunder
shall in no way be terminated, affected or impaired by reason of the granting by
Landlord of any indulgences to Tenant or by reason of the assertion against
Tenant of any of the rights or remedies reserved to Landlord pursuant to the
provisions of said Tenant or by relief of the Tenant from any of the Tenant's
obligations under said Lease by operation of law or otherwise, the undersigned
hereby waiving all suretyship defense. The undersigned further covenants and
agrees that this Guaranty shall remain and continue in full force and effect as
to any renewal, modification or extension of the Lease whether or not the
undersigned shall have received any notice of or consented to such renewal,
modification or extension.

     The undersigned further agrees that its liability hereunder shall be
primary, and that in any right of action which shall accrue to the Landlord
under the Lease, the Landlord may, at its option, proceed against the
undersigned and the Tenant, jointly or severally, may proceed against the
undersigned without having commenced any action against or having obtained any
judgment against the Tenant.

     It is agreed that the failure of the Landlord to insist in any one or more
instances upon strict performance or observance of any of the terms, provisions
or covenants of the Lease or to exercise any right therein contained shall not
be construed or deemed to be a waiver or relinquishment for the future of such
term, provision, covenant or right but the same shall continue and remain in
full force and effect. Receipt by the Landlord of rent or other payments with
knowledge of the breach of any provision of the Lease shall not be deemed a
waiver of such breach.

     No assignment or other transfer of the Lease or any interest therein by any
party shall operate to extinguish or diminish the liability of the undersigned
hereunder except as otherwise provided in Section 15.A of the Lease.

     To the extent that Landlord is required to remit any amount previously paid
to Landlord by Tenant, including but not limited to those remitted pursuant to
the order of any bankruptcy court, Guarantor shall be obligated to reimburse
Landlord for the amount of such repayment.

     IN WITNESS WHEREOF, this Guaranty is executed this 30TH day of July, 1999.

               scheduled time periods, as deemed advisable by Landlord and/or
               its agents, in their sole discretion, require that persons

               its agents, in their sole discretion, employ such other security
               measures as but not limited to the search of all persons,
               parcels, packages, etc., entering and leaving the Building, the
               evacuation of the Building and the denial of access of any person
               to the Building.

          (c)  Tenant hereby assents to the exercise of the above discretion of
               Landlord and its agents, whether done acting under reasonable
               belief of cause or for drills, regardless of whether or not such
               action shall in fact be warranted and regardless of whether any
               such action is applied uniformly or as aimed at specific persons
               whose conduct is deemed suspicious.

          (d)  The exercise of such security measures and the resulting
               interruption of service and cessation or loss of Tenant's
               business, if any, shall never be deemed an eviction or
               disturbance of Tenant's use and possession of the Premises, or
               any part thereof, or render Landlord liable to Tenant for damages
               or relieve Tenant from Tenant's obligations under this Lease.

          (e)  Tenant agrees that it and its employees will cooperate fully with

occupancy thereof. Tenant shall not

make or permit any use of the Premises which directly or indirectly is forbidden
by law, ordinances, governmental regulations or order or direction of applicable
public authority, or which may be dangerous to person or property.

     20. Tenant shall not use or permit to be brought into the Premises or the
Building any flammable oils or fluids, or any explosive or other articles deemed
hazardous to persons or property, or do or permit to be done any act or thing
which will invalidate or which if brought in would be in conflict with any
insurance policy covering the Building or its operation, or the Premises, or any
part of either, and will not do or permit to be done anything in or upon the
Premises, or bring or keep anything therein, which shall not comply with all
rules, orders, regulations or requirements of any organization, bureau,

appurtenances, contents or operation. The foregoing prohibitions shall include

                                  APPENDIX "C"

     Landlord and Tenant agree as follows:

     1. Tenant agrees to cause its architect to provide plans and specifications
in form and substance sufficient to allow Landlord to approve same and obtain
all required governmental permits for all of the Work on or before August 15,
1999, for Landlord's review and approval in order to enable Landlord to complete
prior to the Commencement Date the Premises in accordance therewith.
Notwithstanding the date by which such plans and specifications are finalized or
approved, Tenant's obligation to pay rent shall commence on Rent Commencement
Date.

     2. All such plans and specifications shall be subject to Landlord's
reasonable approval and upon approval shall constitute the "TI Plans and
Specifications". Upon agreement as to such plans and specifications, Landlord
agrees to cause its general contractor ("the General Contractor") to bid same,
which bids shall be reviewed by the General Contractor and Tenant, who shall
mutually agree on which bids to accept. Upon reaching agreement as to which bids
are to be accepted, Landlord shall provide Tenant with a budget for the cost of
the Work which shall be subject to Tenant's reasonable approval ("TI Budget").
The TI Budget may be amended by a change order in writing signed by Landlord and
Tenant setting forth any change in the Work, any increase or decrease in cost
resulting therefrom, and any change in time for performance of the Work
resulting therefrom ("Change Order").

     3. Landlord agrees to provide an allowance for all tenant improvement
work in an amount of EIGHT HUNDRED FORTY-FOUR THOUSAND SEVEN HUNDRED SIXTY
($844,760.00) DOLLARS, up to TWO HUNDRED FORTY-ONE THOUSAND THREE HUNDRED
SIXTY ($241,360.00) DOLLARS of which may be used for Tenant's telephone, data
and other cabling, and for architects' and engineers' fees. It is understood
that Tenant shall pay for all Work to the extent that the cost of same
exceeds the foregoing allowance, but Tenant shall not be responsible to the
extent such costs exceed the amount of the TI Budget (as may be increased by
Change Order), and Landlord shall pay same. To the extent any portion of the
aforesaid allowance is not used, an amount, not to exceed TWO HUNDRED
FORTY-ONE THOUSAND THREE HUNDRED SIXTY ($241,360.00) DOLLARS, may be applied
toward a reduction in Base Rent amortized over the term of the Lease at an
amortization rate of ten (10%) percent.

     4. Landlord agrees that the General Contractor shall not be entitled to any
construction management fee, general contractor's fee, overhead, profit or
general conditions, which exceed in the aggregate more than ten (10%) percent of
the cost of the Work.

     5. The provisions of this Work Letter Agreement supplement are specifically
subject to all provisions of the Lease.
