                            MCCANN-ERICKSON SOUTHWEST

Lake Helen, Florida 32744

Dear Peter:

We are delighted to have been chosen the advertising agency for your
Attorneys.com venture. We are anxious to get started and we are sending this
letter of agreement for the project we discussed.

Scope of Work
-------------
McCann-Erickson will provide the following services:

     1.  Develop a communications strategy, including the proprietary
         McCann-Erickson strategic tools - the Brand Footprint(TM)and Selling
         Strategy(TM).

     2.  Explore multiple creative avenues, including a spokesperson and assist
         in hiring spokesperson and creating storyboards should one be selected.

     3.  Upon agreement to a creative direction, write and produce the TV and
         radio commercials including billboard advertising if appropriate.

     4.  Design a media kit template, including some inexpensive packaging and
         some blank letterhead to be used for enclosures

     5.  Design identity package

     6.  Create a CD ROM that will include a filmed introduction, the TV spots
         and a filmed conclusion

     7.  Design a logo/identity package

     8.  Attorneys.com shall have the right to select all outside vendors
         including a director and post-production personnel

FEES
The manpower fee to deliver the above services is $512,206. We are willing to
accept 33% or $169,028 in PCNA unregistered common stock ( the "Stock") with
piggy-back registration rights, and $343,557 in cash. The Stock will be earned
in three equal, consecutive monthly payments, beginning June 30, 2000. The
number of shares of Stock shall be determined based upon the average of the
daily closing prices as reported by Nasdaq for the month then ended, less a 20%
discount. The unregistered shares of Stock shall have piggyback registration
rights as specified in Exhibit A.

o    Please understand that the fees cover only agency time; all out-of-pocket
     costs will be billed to you at cost.

o    The fee has been discounted to accommodate your request to keep startup
     costs low. We offer this discount because we will be conducting the media
     planning and placement for a period of one year
<PAGE>

     after the creative is completed. Should you decide to use a firm other than
     McCann-Erickson to plan or place media, during the one-year period after
     the creative is completed, there will be an additional fee charged of
     $200,000. McCann-Erickson's media fees will be within industry standards.
     Further, if for some reason you were not to place media, this fee would not
     be charged.

TERMS

     o   All fees must be paid in advance of work commencing.

     o   Out-of-pocket costs will be paid on the vendor's terms. It has been our
         experience that most expect dot.coms to pay cash in advance, and in
         television production, pre-payment is standard practice for all
         clients.

     o   Out-of-pocket costs will be estimated and presented for approval before
         work commences. No out-of-pocket costs will be assessed without
         approval.

     o   This project is expected to take no more than three months to complete.

I hope you find these fees and terms agreeable. If you do, please sign the
document as indicated below. If you have any questions or issues, please call me
as soon as possible to resolve. As media becomes a more immediate issue, we will
look to create a more ongoing, long-term agreement between our two companies.

We are thrilled to be working with you and anxious to get started. Thank you for
selecting us as your agency. I assure you that Attorneys.com will get the best
of what we have to offer.

Best regards,

                  a.       PIGGYBACK. If at any time or from time to time, the
                           Company shall decide to register any of its Common
                           Stock, either for its own account or the account of a
                           security holder or holders, in a registration
                           statement covering the sale of Company's Common Stock
                           under the Securities Act, the Company will: (1)
                           promptly give to Holder written notice thereof (which
                           shall include a list of the jurisdictions in which
                           the Company intends to attempt to qualify such Common
                           Stock under the applicable blue sky or other state
                           securities laws if the Common Stock is not a "covered
                           security" within the meaning of the National
                           Securities Markets Improvement Act of 1996); and (2)
                           include in such registration statement (and any
                           related qualification under blue sky laws) all the
                           Registrable Securities specified in a written
                           request, made within 30 days after receipt of such
                           written notice from the Company, except as set forth
                           in Section 2 b. below.

<PAGE>

                  b.       UNDERWRITING. In the event that the registration
                           statement filed pursuant to Section 2 shall be for an
                           underwritten public offering, the right of Holder to
                           registration pursuant to Section 2 shall be
                           conditioned upon the Holder's participation in the
                           underwriting and the inclusion of such Holder's
                           Registrable Securities in the underwriting to the
                           extent provided herein. The Holder proposing to
                           distribute its Common Stock through such underwriting
                           shall (together with the Company and any shareholders
                           distributing their Common Stock through such
                           underwriting) enter into an underwriting agreement in
                           customary form with the managing underwriter or
                           underwriters selected for such underwriting by the
                           Company. Notwithstanding any other provision of this
                           Section 2, if the managing underwriter determines
                           that marketing factors require a limitation of the
                           number of shares to be underwritten, the managing
                           underwriter may limit the number of Registrable
                           Securities to be included in the registration and
                           underwriting, or may exclude the Registrable
                           Securities entirely from such registration and
                           underwriting. The Company shall so advise the Holder
                           and the number of shares of Registrable Securities
                           that may be included in the registration and
                           underwriting shall be allocated among the Holder and
                           any other selling shareholders in proportion
                           (excluding warrants or their equivalent issued to the
                           underwriter of a registered public offering which may
                           be included in their entirety), as nearly as
                           practicable, to the respective amounts of securities
                           entitled to inclusion in such registration held by
                           the Holder and such selling shareholders at the time
                           of filing the registration statement. If the
                           Registrable Securities are excluded, no securities
                           may be sold for the account of any shareholders or
                           securityholders. If the Holder disapproves of the
                           terms of any such underwriting, it may elect to
                           withdraw therefrom by written notice to the Company
                           and the underwriter. Any Registrable Securities
                           excluded or withdrawn from such underwriting shall
                           not be transferred in a public distribution prior to
                           90 days after the effective date of the registration
                           statement relating thereto.

         3.       Expenses of Registration. Except as provided herein, the
                  Company shall pay all expenses incurred in connection with a
                  registration pursuant to Section 2 hereof. Expenses incurred
                  in connection with any registration or qualification pursuant
                  to this Agreement include, without limitation, all
                  registration, filing, and qualification fees, printing
                  expenses, fees and disbursements of counsel for the Company,
                  and expenses of any special audits incidental to or required
                  by such registration; provided, however, that such expenses
                  shall not include fees of legal counsel to the Holder, selling
                  expenses of the Holder, or underwriting fees, discounts, or
                  commissions relating to Registrable Securities.

         4.       Registration Procedures. In the case of each registration or
                  qualification effected by the Company pursuant to this
                  Agreement, the Company will keep Holder advised in writing as
                  to the initiation of each registration or qualification and as
                  to the completion thereof. The Company will use its best
                  efforts to:
<PAGE>

                  a.       keep such registration and qualification effective
                           for a period of 60 days or until the Holder has
                           completed the distribution described in the
                           registration statement relating thereto, whichever
                           first occurs; and

                  b.       furnish such number of prospectuses and other
                           documents incident thereto as Holder from time to
                           time may reasonably request.

         5.       Indemnification.

                  a.       The Company will indemnify Holder, each of the
                           Holder's officers and directors, and each person
                           controlling such Holder, with respect to such
                           registration or qualification effected pursuant to
                           this Agreement, and each underwriter, if any, and
                           each person who controls any underwriter of the
                           Registrable Securities held by or issuable to Holder,
                           against all claims, losses, damages, and liabilities
                           (or actions in respect thereto) arising out of or
                           based on any untrue statement or alleged untrue
                           statement of a material fact ("Untrue Statement")
                           contained in any prospectus, offering circular or
                           other document (including any related registration
                           statement, notification or the like) incident to any
                           such registrations or qualification, or based on any
                           omission or alleged omission to state therein a
                           material fact required to be stated therein or
                           necessary to make the statements therein not
                           misleading ("Omission"), and will reimburse Holder,
                           each of the Holder's officers and directors, and each
                           person controlling Holder, each such underwriter and
                           each person who controls any such underwriter, for
                           any legal and any other expenses reasonably incurred
                           in connection with investigating or defending any
                           such claim, loss, damage, liability or action.
                           Provided, however, the Company will not be liable in
                           any such case to the extent that any such claim,
                           loss, damage or liability arises out of or is based
                           on (i) any Untrue Statement or Omission based upon
                           written information furnished to the Company by an
                           instrument duly executed by Holder or an underwriter
                           specifically for use therein, (ii) failure to
                           register or qualify the Common Stock under any state
                           securities law or (iii) the failure of an
                           underwriter, broker-dealer sales or agent to be
                           registered under any state securities laws (clauses
                           (i), (ii) and (iii) are collectively, the "Excluded
                           Provisions").

                  b.       Holder will, if Registrable Securities held by or
                           issuable to such Holder are included in the Common
                           Stock as to which such registration or qualification,
                           is being effected, indemnify the Company, each of its
                           directors and officers who sign such registration
                           statement, each underwriter, if any, of the Company's
                           Common Stock covered by such a registration
                           statement, and each person who controls the Company
                           and each underwriter within the meaning of the
                           Securities Act, against all claims, losses, damages
                           and liabilities (or actions in respect thereof)
                           arising out of or based on any Excluded Provisions.

                  c.       Each party entitled to indemnification under this
                           Section 5 (the "Indemnified Party") shall give notice
                           to the party required to provide indemnification (the
                           "Indemnifying Party") promptly after such Indemnified
                           Party has actual knowledge of any claim as
<PAGE>

                           to which indemnity may be sought and shall permit the
                           Indemnifying Party to assume the defense of any such
                           claim or any litigation resulting therefrom, provided
                           that counsel for the Indemnifying Party, who shall
                           conduct the defense of such claim or litigation,
                           shall be approved by the Indemnified Party (whose
                           approval shall not be unreasonably withheld), and the
                           Indemnified Party may participate in such defense at
                           such party's expense. No Indemnifying Party, in the
                           defense of any such claim or litigation, shall,
                           except with the consent of the Indemnified Party,
                           consent to entry of any judgment or enter into any
                           settlement which does not include as an unconditional
                           term thereof the giving by the claimant or plaintiff
                           to such Indemnified Party of a release from all
                           liability in respect to such claim or litigation. If
                           the Indemnified Party fails to execute a release or
                           other settlement agreement under circumstances where
                           all of the conditions of the preceding sentence have
                           been met, the Indemnifying Party shall have no
                           further obligation to the Indemnified Party pursuant
                           to this Agreement or otherwise.

         6.       Information by Holder. The Holder of Registrable Securities
                  included in any registration shall (i) furnish to the Company
                  such written information regarding such Holder and the

June, 2000, by and between NEW BOSTON MONTVALE LIMITED PARTNERSHIP, a Delaware
Limited Partnership, having a business address at One Longfellow Place, Suite
3612, Boston, Massachusetts 02114 (hereinafter called "LANDLORD") and
SIMPLAYER.COM, LTD. (hereinafter called "TENANT").

         SECTION I. PREMISES. Landlord leases to Tenant, and Tenant hereby hires
and takes from Landlord the following described premises subject to the
mortgages as hereinafter provided, and to all encumbrances of record.

         The "PREMISES" are that portion of a building in the Town of Stoneham,
Commonwealth of Massachusetts, having a mailing address of 91 Montvale Avenue,
Stoneham, Massachusetts 02180 (hereinafter called the "BUILDING") consisting of
a total of approximately 16,355 square feet of net rentable area (the "NET
RENTABLE AREA") on the second and third floors of the Building, and more
particularly consisting of approximately 8,084 square feet of net rentable area
on the second floor of the Building (the "SECOND FLOOR SPACE") as set forth on
EXHIBIT A attached hereto and made a part hereof, which shall be delivered to
the Tenant upon the execution hereof, and an additional 8,271 square feet of net
rentable area on the third floor of the Building (the "THIRD FLOOR SPACE") as
set forth on EXHIBIT A-1 attached hereto and made a part hereof. The Building
and the parcel of land on which it is located are hereinafter referred to as the
"PROPERTY" as described in EXHIBIT A-2.

         Landlord reserves and excepts all rights of ownership and use in all
respects outside the Premises, including, without limitation, the Building and
all other structures and improvements and plazas, parking areas, and common
areas on the Property, except that at all times during the term of this Lease,
Tenant shall have a reasonable means of access from the street to the Premises
on a 24 hour per day, seven day per week basis, including elevator access.
Without limitation of the foregoing reservation of rights by Landlord, it is
understood that with regard to the Building and the Property, Landlord in its
sole discretion shall have the right to change, relocate and eliminate
facilities therein, to permit the use of or lease all or part thereof for
exhibition and displays, to sell, lease or dedicate all or part thereof to
public use; and further that Landlord shall have the right to make changes in,
additions to and eliminations from the Building, and other structures and
improvements on the Property, the Premises excepted. Landlord's exercise of its
rights hereunder shall not unreasonably interfere with Tenant's use of the
Premises nor reduce the number of parking spaces allotted to Tenant under this
Lease.

         SECTION II. USE. Tenant shall have the right to use, in common with
others so entitled, all common areas associated with the Building and located in
the Building or on the Property including all hallways, elevator(s), if any,
loading dock(s), access ways, walkways, parking areas, courtyards and landscaped
areas. Tenant shall have the exclusive right to use twelve (12) reserved parking
spaces, and up to an additional forty-three (43) unreserved parking spaces in
common with others on the parking area located on the Property (the "MAXIMUM
PARKING LOT USAGE"). Tenant covenants that at no time during the term of this
Lease shall it exceed the Maximum Parking Lot Usage. Tenant shall use the
Premises for general office use and other reasonable uses incidental and related
thereto, provided that Tenant shall not use, permit nor suffer anything to be
done or anything to be brought into or kept in the Premises or on

                                      -1-
<PAGE>

the Property which in Landlord's reasonable judgment occasions discomfort or
annoyance to any other tenants or occupants of the Building and parking area, or
which may tend to impair the reputation or appearance of the Building or the
Property, or tend to materially interfere with the proper and economic operation
of the Building, parking area or the Property by Landlord, or which shall
violate the Certificate of Occupancy for the Building or any law or regulation
of any governmental body. If, due to Tenant's use of the Premises, improvements
or alterations to the Premises or the Building are necessary to comply with any
requirements imposed by law, Tenant shall pay the entire cost of such
improvements or alterations.

         Tenant covenants that at no time during the term of this Lease shall
the Premises be occupied at one time by more than seventy-five (75) employees or
independent contractors hired in lieu of employees of Tenant (the "MAXIMUM
OCCUPANCY"). Landlord shall be entitled to access to the Premises during regular
business hours to monitor the occupancy of the Premises provided such monitoring
will not interfere with the business operations of Tenant..

         Tenant covenants that it will move into the Premises promptly at the
commencement of the term hereof and, will not abandon the Premises without the
prior written notice to Landlord.

         SECTION III. TERM With respect to the Second Floor Space the term of
this Lease shall commence upon the delivery of the Second Floor Space by
Landlord to Tenant (the "COMMENCEMENT DATE"), and with respect to the entire
Premises the term shall commence on August 1, 2000 and shall terminate on July
31, 2005. Upon the Commencement Date Landlord shall deliver the Second Floor
Space free and clear of all tenants and in good working order.

         SECTION IV. RENT. Tenant shall pay the following "RENT":

         (a) From and after the date which is the earlier to occur of (i)
occupancy of the Second Floor Space by Tenant for business purposes or (ii)
August 15, 2000iii) (the "SECOND FLOOR RENT COMMENCEMENT DATE") Tenant shall pay
annual "RENT" on the Second Floor Space equal to the product of the net rentable
area of the Second Floor Space as set forth in Section I of this Lease (8,084
square feet) multiplied by $21.50.

         (b) From and after August 1, 2000 (the "THIRD FLOOR RENT COMMENCEMENT
DATE") Tenant shall pay annual Rent on the Third Floor Space equal to the
product of the Net Rentable Area of the Third Floor Space (8,271 square feet) as

         The Rent shall be paid in equal installments of one-twelfth (1/12) of
the annual Rent in advance on the first day of each calendar month.

         Tenant shall pay a proportionate share of such monthly installment for
any fraction of a calendar month at the beginning or end of the Lease term.

         Tenant shall pay the Rent and Additional Rent without demand or notice
and without deduction, abatement, counterclaim, or set-off, to the Landlord in
care of New Boston Montvale Limited Partnership, P.O. Box 42001, Providence,
Rhode Island 02940, or at such other place as designated from time to time by
Landlord in writing.

         In the event that the Rent is not paid within five days when due,
Landlord shall assess and Tenant shall pay a late charge in an amount equal to
interest at the rate of one and one-half percent (1 1/2%) per month on the
unpaid balance from the date said Rent became due. All other charges which
Tenant is required to pay hereunder, together with all interest and penalties
that

                                      -2-
<PAGE>

may accrue thereon, shall be deemed to be "ADDITIONAL RENT" and in the event of
non-payment thereof by Tenant, beyond applicable notice and cure periods,
Landlord shall have all the rights and remedies with respect thereto as would
accrue to Landlord for non-payment of Rent.

         SECTION V.   CONSTRUCTION AND PREPARATION OF THE PREMISES.

         (a) Landlord's Work. Landlord shall do the work shown on EXHIBIT B
attached hereto and made a part hereof as the work on the part of Landlord in a
good and workmanlike manner in accordance with all laws, rules, regulations and
ordinances applicable thereto, and in accordance with the scope of work set
forth on said EXHIBIT B (herein referred to as "Landlord's Work"). Landlord's
Work shall be done at Landlord's expense except as otherwise provided on EXHIBIT
B. To the extent practical, Landlord shall give advance notice to the Tenant of
the approximate date upon which Landlord's Work shall be "substantially
completed". "Substantial Completion" or "substantially completed" shall mean
that Landlord's Work has been completed, except for minor details of mechanical
adjustment, decoration and finish which do not materially interfere with
Tenant's ability to use and occupy the Premises for the purposes permitted
hereunder. If Substantial Completion of Landlord's Work is delayed due to any
act or omission of Tenant or Tenant's representative, including, but not limited
to, any delay by Tenant in submission of plans, drawings, specifications or
other information or in approving any working drawings or estimates or in giving
any authorization or approval, the Premises shall be deemed substantially
completed on the date when they would have been ready but for such delay. The
taking of possession of the Premises by Tenant shall be conclusive evidence of
the acceptance of the Premises by Tenant and that the Premises are in good and
satisfactory condition, in accordance with Landlord's obligations hereunder.

         (b) Tenant's Work. Tenant shall do the work, if any, shown on EXHIBIT B
(herein referred to as "Tenant's Work"), as the work on the part of the Tenant,
in a good and workmanlike manner in accordance with "Plans and Specifications"
(as hereinafter defined) which have Landlord's written approval prior to the
commencement of Tenant's Work, which approval shall not be unreasonably
withheld, conditioned or delayed. Tenant shall furnish and install any and all
necessary trade fixtures, equipment and other items necessary for the proper
conduct of Tenant's business. "PLANS AND SPECIFICATIONS", as used in this
Section V(b) and in Section XIII, shall mean documents and drawings sufficient
for contract bidding and work completion. All of the foregoing work and all work
Tenant may undertake pursuant to Section XIII of this Lease shall be done in
accordance with all laws, rules, regulations and ordinances applicable thereto,
including, if necessary, compliance with the Americans With Disabilities Act, as
amended from time to time, and the acquisition by Tenant of a Building Permit
from the municipal department having jurisdiction, if required. In no event
shall Landlord be required to provide or install any trade fixtures or
equipment. Tenant agrees to employ for any work it may do pursuant to Sections
V(b) and XIV of this Lease, one or more responsible contractors whose labor will
work in harmony with other labor working in and about the Building and Property
and with suppliers of materials for use in construction in and about the
Building and Property, and especially Tenant agrees that it will not do or
permit to be done anything which would cause any labor difficulty in connection
with any construction in and about the Building and Property. Tenant's Work
shall be performed in a manner as to minimize

                                      -3-
<PAGE>

interference with the proper and economic operation of the Building and the
operations of other tenant's in the Building and Landlord may direct such work
to be performed after regular business hours so as to minimize such"
interference if reasonably necessary. Tenant shall require all contractors
employed by Tenant to carry Worker's Compensation Insurance in accordance with
statutory requirements and to carry Commercial General Liability Insurance and
Automobile Liability Insurance covering such contractors in or about the
Premises, Building and Property in amounts not less than One Million Dollars
($1,000,000) combined single limits for property damage, for injury or death of
more than one person in a single accident, and to submit certificates of
insurance evidencing such coverage to Landlord prior to commencement of such
work. Tenant agrees to indemnify and hold harmless Landlord and its management
agent from all claims, actions, demands and causes of actions occasioned by
Tenant's contractors being on or about the Premises, or the Building or the
Property of which the same form a part and from Tenant's contractors performing
work in the Premises.

         All contractors, subcontractors, mechanics, laborers, materialmen, and
others who perform any work, labor or services, or furnish any materials, or
otherwise participate in the labor or services, or furnish any materials, or
otherwise participate in the improvement of the Premises shall be and are hereby
given notice that Tenant is not authorized to subject Landlord's interest in the
Premises, Building or Property to any claim for mechanics', laborers' and
materialmen's liens, and all persons dealing directly or indirectly with Tenant
may not look to the Premises, Building or Property as security for payment.
Tenant shall save Landlord harmless from and against all expenses, liens, claims
or damages to either property or person which may or might arise by reason of
the making of any such additions, improvements, alterations and/or
installations.

         SECTION VI. BUILDING AND EQUIPMENT. Landlord shall keep in serviceable
condition and repair and replace as necessary, the structure (including the
foundation, floor slabs, and supporting columns and beams) and exterior of the

equipment and serviceable lines installed by Tenant and except otherwise
provided in Section VIII), and the exterior parking area serving the Building.
The Landlord shall comply with applicable governmental rules, regulations, laws
and ordinances affecting the Building and the Property, including, without
limitation, the Americans with Disabilities Act, (excluding the Premises for
which Tenant shall be responsible for all compliance with the Americans with
Disabilities Act)unless the violation is caused by Tenant or Tenant's use of the
Premises. The Landlord shall keep the sidewalks, common corridors, stairway,
elevators, and all other means of ingress and egress for the Premises and all
public portions of the Building in serviceable repair and in a reasonably clean
and safe condition. Landlord reserves the right to interrupt, curtail, stop and
suspend the furnishing of any services and operation of the plumbing and
electrical, heating, ventilation and air conditioning systems and elevators when
necessary by reason of accident or emergency or for repairs, alterations,
replacements or improvements, which may become necessary or when it cannot
secure supplies or labor or by reason of any other cause beyond its control,
without liability or any abatement of Rent or Additional Rent being due thereby.

                                      -4-

         Notwithstanding the foregoing, if as a result of :

         (1) Landlord's negligence, misconduct or intentional actions, or
         failure to fulfill any covenant or provision of this Lease on its part
         to be performed (unless such failure is caused in whole or in part by
         the action or inaction of Tenant) which negligence, misconduct,
         intentional actions, or failure affects the life safety, HVAC,
         mechanical, electrical and/or plumbing systems of the Building
         ("ESSENTIAL SERVICES"); or (2) the United States Environmental
         Protection Agency, or any other federal, state or municipal
         governmental agency, officially declaring the Building or the Premises
         untenantable (unless such condition is caused in whole or in part by
         the action or inaction of Tenant),

the conduct of Tenant's business is materially and adversely interfered with and
precludes the Tenant's use of the Premises or a portion of the Premises
("MATERIAL FAILURE TO PROVIDE ESSENTIAL SERVICES"), then Tenant shall have the
right hereinafter set forth. During such period of Material Failure to Provide
Essential Services, Landlord will, if reasonably practical, arrange for the
provision of Essential Services on an interim basis via temporary measures until
final corrective measures can be accomplished. In the event a Material Failure
to Provide Essential Services is not remedied by Landlord within ten (10)
consecutive business days after written notice thereof from a corporate officer
of Tenant, then Tenant shall have the right to abate the Rent and Additional
Rent due or becoming due under this Lease until said Material Failure to Provide
Essential Services is remedied by Landlord, but only to the extent that the
foregoing conditions materially and adversely interfere with Tenant's business
in the Premises or a portion of the Premises. Said Rent abatement shall be taken
as a credit in four (4) equal installments against Tenant's rental obligations
for the next four (4) successive calendar months hereunder.

         SECTION VII. FLOOR LOAD, HEAVY MACHINERY. Tenant shall not place a load
upon any floor of the Premises exceeding the floor load per square foot area
which floor was designed to carry and which is allowed by law. Business machines
and mechanical equipment shall be placed and maintained by Tenant at Tenant's
expense in settings sufficient to prevent transmission of noise and vibration to
any other part of the Building in which the Premises are located. Any moving of
any machinery and/or equipment into, out of, or within the Premises shall be
done only with the prior written consent of Landlord in each instance, which
consent shall not be unreasonably withheld, conditioned or delayed, and shall be
at the sole risk and hazard of Tenant and Tenant will indemnify and save
Landlord harmless against and from any liability, loss, injury, claim or suit
resulting directly or indirectly from such moving. In the event riggers shall be
required to accomplish such moving, only persons holding a Master Rigger's
License shall perform the work. Tenant shall not in any way break, cut into, or
damage the exterior perimeter walls or insulating panels of the Building in
installing, ventilating or exhausting its equipment or in any other manner,
without the prior written consent of Landlord not to be unreasonably withheld,
conditioned or delayed.

         SECTION VIII. SERVICES. Landlord shall provide throughout the term of
this Lease:

         (a) Access to the Building and Premises from the lobby Monday through
Friday, excepting legal holidays in the Commonwealth of Massachusetts,

are shown on EXHIBIT C attached hereto. Normal business hours shall mean Monday
through Friday, 8:00 AM to 6:00 PM, holidays excepted, Saturdays 8:00 AM to 1:00
PM. At all other times Landlord shall provide limited access to the Building and
Premises in accordance with such Building standard entry system as shall from
time to time be in effect. The Landlord reserves the right to alter the Building
standard entry system as it sees fit. Notwithstanding any provision in this
Lease to the contrary, Tenant shall always have 24 hours, seven days per week
access to the Premises during the term of this Lease, including elevator
service.

         (b) Use, in common with others, of all elevator facilities at all
times.

         (c) Building Standard heat and air conditioning during normal business
hours which is reasonably required for reasonably comfortable occupation of the
Premises, under normal business operation at an occupancy of not more than one
person per 218 square feet of Net Rentable Area and an electrical load not
exceeding 3 watts per square foot of Net Rentable Area, subject to all
governmental laws, regulations or restrictions now or hereafter in force
pertaining to the furnishing or use of such heat and air conditioning. Landlord
shall provide heat and air conditioning to Tenant at other than normal business
hours, provided that Tenant pays Landlord its charges for supplying the same. At
the commencement of the term of this Lease, Landlord's charge for supplying heat
and air conditioning to Tenant at other than normal business hours is $30 per
hour. Landlord reserves the right to increase this charge from time to time
throughout the term of this Lease upon prior written notice to Tenant. Tenant
shall not introduce into the Premises personnel or equipment which overloads the
capacity of the Building HVAC systems or in any other way interferes with any
system's ability to perform adequately its proper functions; provided, however,
if Tenant violates the foregoing, Landlord may, at its option after the
expiration of applicable notice and cure periods, elect to provide supplementary
systems or otherwise take steps to cure such violation, at Tenant's sole
reasonable cost and expense in all respects including, without limitation,
system installation (and removal) and continuing costs of operation.

         (d) Cause the Premises to be kept reasonably clean, provided the
Premises are kept in order by Tenant. The cleaning services provided hereunder
are set forth on EXHIBIT D attached hereto and made a part hereof which
represents the scope of the cleaning services. The cleaning services shall be
provided only Monday through Friday, legal holidays excepted. Notwithstanding
the foregoing, at no time and under no circumstances shall Landlord have any
responsibility for the storage or removal of any "medical waste", "infectious
waste", "hazardous medical waste", "hazardous waste", as such terms may from
time to time be defined in such municipal, state and federal statutes, laws,
ordinances, rules and regulations as may apply to Tenant or to the Premises
demised to Tenant because of the business, profession or activity carried on in
the Premises by Tenant, Tenant's servants, agents, employees, invitees or anyone
claiming by, through or under Tenant.

         (g) Snow and ice removal from all walkways, entrances and parking
areas.

         SECTION IX. UTILITIES. As of the Commencement Date, Tenant shall pay
for all utilities furnished to the Premises by Landlord or any other supplier,
which may include cable service, water and sewer charges, electricity, gas, and
telephone services, and all costs associated with the heating, ventilating and
air conditioning units serving the Premises. The listing of any utility service
in the previous sentence shall not constitute a representation that such utility
service is available to the Premises. To the extent Landlord elects to
separately meter the Premises for water, gas or electricity usage, a separate
meter serving only the Premises shall be installed, maintained, repaired and
replaced, as necessary, at Landlord's expense, and the cost of all such
utilities shall be billed directly to Tenant by the appropriate public utility
company.

         (a) Demand and Usage. To the extent not separately metered to the
Premises, Landlord shall supply electricity, as supplied to Landlord by the
electric utility, to the Premises to meet a demand requirement (utilizing the
demand measurement standards established by the supplying utility under the rate
applicable to Landlord) not to exceed 3.0 watts per square foot of Net Rentable
Area for premises lighting and convenience outlets. Tenant agrees Tenant's use
of the Premises shall not exceed such requirements or any limits from time to
time established under applicable laws or regulations, or regulations of the
utility provider(s). In addition to the Rent set forth in Section IV of this
Lease and as part of the Additional Rent due under this Lease, Tenant shall pay
Landlord the sum of $1.00 per square foot of Net Rentable Area per annum as an
"ELECTRICITY CHARGE". The Electricity Charge shall be paid in equal installments
of one-twelfth (1/12)of the Electricity Charge each in advance on the first day
of each calendar month without deduction, demand, or set off, together with the
Rent and Additional Rent described in this Lease. If Tenant's electricity demand
exceeds the foregoing, Tenant shall pay the cost of such excess electricity
demand.

         (b) Consumption. Landlord's supply of electricity shall allow for a
rate of consumption by Tenant of 3.0 watts per square foot of Net Rentable Area,
multiplied by sixty (60) hours of consumption per week. If Tenant's consumption
exceeds such allowance, Tenant shall pay the excess costs.

         (c) Survey. From time to time during the Term or any extension thereof,
Landlord shall have the right to have an electrical consultant selected by
Landlord make a survey of Tenant's electrical usage. If such survey shows that
Tenant has exceeded the aforesaid requirements or standards set forth in the
Lease, then within thirty (30) days and in addition to any other rights Landlord
may have hereunder, Tenant shall reimburse Landlord, as part of Tenant's
Additional Rent, for the cost of such survey and the cost, as determined by such
consultant, of electricity usage or demand in excess of such requirements or
standards.

         (d) Escalation. Furthermore, it being the intention of the parties that
the Rent set forth in Section IV of this Lease be net of any cost to Landlord of
providing electric current to the Premises, if Landlord is furnishing electric
current to the Premises (i.e. Tenant's Premises is not separately metered by the
supplying utility company), Tenant shall pay, as part of Tenant's Additional
Rent, an Escalation Charge calculated and payable as follows:

                  1. If Landlord's cost in supplying electricity to the Premises
for any Operating Year exceeds the Electricity Charge (such excess being called
"Tenant Excess

                                      -7-
<PAGE>

Electricity Expenses"), Tenant shall pay to Landlord, as part of Tenant's
Additional Rent, an amount equal to the Tenant Excess Electricity Expenses for
such year (and at that rate for a partial year and extrapolated to full
occupancy if total Building electric current figures are used to calculate
Tenant Excess Electricity Expenses). In determining and calculating the amount
of the Tenant Excess Electricity Expenses for and in respect of any Operating
Year, Landlord may utilize electric meters, equipment surveys, engineering
estimates, electric consumption data for the entire Building, or any other
reasonable measurement, calculation and allocation devices and formulas.

                  2. Tenant shall make reasonably estimated escalation payments
on account of the Tenant Excess Electricity Expenses either in monthly
installments or in year-end lump sum, as Landlord shall elect. After the end of
each Operating Year, Landlord shall submit to Tenant an accounting of the Tenant
Excess Electricity Expenses for such Operating Year. If the estimated payments
by Tenant for such Year exceed Tenant's required payment on account of the
Tenant Excess Electricity Expenses for that Operating Year, according to such
statement, Landlord shall credit the amount of overpayment against subsequent
obligations of Tenant (or refund the overpayment if the Term has ended and
Tenant has no further obligations to Landlord). If, however, the required
payments are greater than the estimated payments made by Tenant, Tenant shall
pay to Landlord the difference within thirty (30) days after being billed
therefor by Landlord.

         (e) Service and Metering. Landlord shall have the right at any time and
from time to time to: (i) discontinue furnishing electricity to the Premises
upon at least sixty (60) days' notice to Tenant provided Landlord shall, at
Tenant's expense, separately meter the Premises; or (ii) continue or recommence
to furnish electricity to the Premises, and install at Landlord's expense a
so-called check meter which shall measure the amount of electricity actually
used in the Premises. If Landlord exercises the right described in clause (i),
then from and after the effective date of such discontinuance, Landlord shall
not be obligated to furnish electricity to the Premises. In either case, from
and after the effective date of such new metering:

                  1. The Electricity Charge shall no longer be due from Tenant
to Landlord and Tenant shall cease making payments pursuant to subsection (e)
above;

                  2. In the case described in clause (e)(i) above, Landlord
shall permit Landlord's existing wires, risers, conduits and other electrical
equipment to be used to supply electricity to Tenant provided that the limits
set forth in subsection (a) shall not be exceeded; and

                  3. In the case described in clause (e)(i) above, Tenant shall
arrange for electrical service from, and make payments directly to, the
appropriate utility company; and in the case described in clause (ii) above,
Landlord may bill Tenant monthly for electricity usage as shown by such meter.

         SECTION X.  ADDITIONAL RENT.

         (a) Additional Rent/Taxes. In addition to the Rent set forth in Section
IV of this Lease and as part of the Rent due pursuant to the terms of this
Lease, Tenant shall pay Landlord as Additional Rent the Tax Excess as set forth
in herein. For the purposes of this Section X(a), the following words and terms
shall have the following meaning:

                                      -8-
<PAGE>

                  (1) "TAXES" shall mean the real estate taxes and assessments
imposed upon Landlord with respect to the Property commonly known as 91 Montvale
Avenue, Stoneham, Massachusetts, as such parcel is defined in the records of the
Assessor's Office of Stoneham on January 1, 1999), including all structures
located thereon, and any and all other taxes, levies, betterments, assessments
and charges arising from the ownership and/or operation of the Property, and all
the structures located thereon which are or shall be imposed by a national,
state or municipal or other authorities which are or may become a lien upon
Landlord and the Property, but excluding any fee or penalty levied on Landlord
for late payment thereof. If, or to the extent that, due to a future change in
the method of taxation any franchise, income, profit or other tax shall be
levied against Landlord in substitution or in lieu of any tax which would
otherwise constitute a real estate tax, such franchise, income, profit or other
tax shall be deemed to constitute "Taxes" for the purposes hereof. It is
recognized and agreed by Landlord and Tenant that it is their intention by this
paragraph to include in "Taxes" that which in tax year 2000 was commonly known
in the Town of Stoneham as "real estate taxes", including that portion covered
by the school tax rate, and any type of tax or assessment which may, throughout
the term hereof be substituted, in whole or in part therefore. If, in any tax
year after the tax year 2000, the Town of Stoneham or any of its departments,
shall require Landlord to pay for any service which during the tax year 2000 was
provided by said Town of Stoneham or any of its departments without requiring
payment by Landlord, then all such payments due on account of services rendered
during any tax year after the tax year 2000 shall, for purposes of this Section
X(a)(1) be considered and treated as real estate taxes for the tax year for
which such payments are due. Without in any way limiting the generality of the
preceding sentence some of the services for which the Town of Stoneham or any of
its departments might require payment are: police protection, fire protection,
public schools, library services, park services, building inspections. Water and
sewer use charges are covered elsewhere in this Lease and the same shall not
enter into the calculations made under this Section X(a).

                  (2) "TAX BASE" shall mean the taxes for the fiscal tax year
commencing July 1, 1999 and terminating June 30, 2000 as abated, if abated.

                  (3) "TENANT'S PROPORTIONATE SHARE FOR TAXES" only with respect
to the structures currently located on the Property shall be:

                           (a) With respect to the Second Floor Space, Sixteen
                           and eight one hundredths percent (16.08%) from and
                           after the Second Floor Rent Commencement Date. (b)
                           With respect to the Third Floor Space Sixteen and
                           forty-five one hundredths percent (16.45%) from and
                           after the Third Floor Rent Commencement Date. In the
                           event that the Building is enlarged or diminished or
                           a new building or rentable area are otherwise added
                           to the Property so as to increase or decrease the net
                           rentable area of the Building, Tenant's Proportionate
                           Share for Taxes shall be adjusted to reflect
                           accurately the portion of the net rentable area
                           levied to Tenant.

                  (4) "TAX YEAR" shall mean the twelve-month period commencing
July 1 and ending on June 30 during the term of the Lease.

                                      -9-
<PAGE>

                  (5) "TAX EXCESS" shall mean the amount, in any Tax Year by
which the Taxes for said year exceed the Tax Base, multiplied by Tenant's
Proportionate Share for Taxes. Landlord may bill Tenant annually, semi-annually,
quarterly, or monthly for such Tax Excess as may be due, and Tenant shall pay
such bills within thirty (30) days after receipt of the same.

                  (6) "TAX EXCESS STATEMENT" shall mean a statement setting
forth in reasonable detail the amount payable by Tenant as Tax Excess for said
Tax Year.

                  Appropriate credit against Tax Excess shall be given for any
refund obtained by reason of a reduction in any Taxes by the Courts or other
governmental agency responsible therefor. The original computation of Taxes as
well as reimbursement or payments of additional charges, if any, or allowances,
if any, under the provisions of this Section X shall be based on the assessed
valuations, as set forth in the tax bills issued for the Property with the tax
bill for the Tax Base Tax Year with adjustments to be made at a later date when
the tax refund, if any, shall be paid to Landlord by the taxing authority.
Expenditures for legal fees and for other similar or dissimilar expenses
incurred in obtaining the tax refund shall be charged against the tax refund
before the adjustments are made for the Tax Year. In no event shall Tenant be
entitled to receive a credit against Tax Excess for any Tax Year in an amount
greater than Tenant's share of the Tax Excess for such Tax Year.

                  (7) If the Commencement Date or the Termination Date occurs in
the middle of a Tax Year, Tenant shall be liable for only that portion of the
Tax Excess as the case may be, in respect of said Tax Year represented by a
fraction, the numerator of which is the number of days of the herein term which
falls within Tax Year, and the denominator of which is three hundred sixty-five
(365).

                  (8) In the event of any taking of the Building or Property
whereby this Lease shall not terminate under the provisions of Section XVI, then
for the purposes of determining Tax Excess, in the event the valuation of the
Property is lowered to reflect the taking, the Tax Base shall be lowered
proportionately in relation to the reduced valuation. In the event the taking
includes a portion of the Premises or the Building which it is a part, Tenant's
Proportionate Share shall be adjusted pro-rata to reflect the proportion of the
Premises and/or Property remaining after such taking.

                  (9) Any obligation under this Section X(a) of Tenant which
shall not have been paid at the expiration of the term of this Lease shall
survive such obligation and shall be paid when and as the amount of same shall
be determined to be due.

         (b) Additional Rent/Operating Costs. In addition to the Rent set forth
in Section IV of this Lease and as part of the Rent due pursuant to the terms of
this Lease, Tenant shall pay Landlord as Additional Rent the Operating Cost
Excess as set forth in this Section X(b). For the purposes of this Section X,
the following words and terms shall have the following meaning:

                  1. "OPERATING COSTS" shall mean all reasonable costs incurred

heating and cooling equipment, including, without limitation, those items
described in clauses (a) through (o) inclusive of this Section X(b)(1) shown
above, for the calendar year 2000.

                  (3) "COMPUTATION YEAR" shall mean each calendar year or a
portion thereof beginning with the calendar year 2001.

                  (4) "TENANT'S PROPORTIONATE SHARE FOR OPERATING COSTS" shall
be 32.53%. In the event that the Building is enlarged or diminished so as to
increase or decrease the net rentable area of the Building, Tenant's
Proportionate Share for Operating Costs shall be adjusted to reflect accurately
the portion of the net rentable area leased by tenant. If during a Computation
Year, the Building has an average annual occupancy rate of less than one hundred
percent (100%) of the net rentable square footage, then for the purposes of this
subsection (b)(4) those Operating Costs which are variable depending upon
occupancy levels shall be equitably adjusted as though the Building occupancy
were one hundred percent (100%).

                  (5) "OPERATING COST EXCESS" shall mean the amount, in any
Computation Year by which the Operating Costs for said year exceed the Operating
Costs Base, multiplied by Tenant's Proportionate Share for Operating Costs.

                                      -13-
<PAGE>

                  (6) "OPERATING COST EXCESS STATEMENT" shall mean a statement
setting forth in reasonable detail the amount payable by Tenant as Operating
Cost Excess for the Computation Year.

                  Landlord may, at its sole discretion, bill Tenant monthly,
quarterly, semi-annually or annually for such Operating Cost Excess. Each bill
shall set forth on an item by item basis the increase over the Operating Cost
Base of the cost of each item for the month, quarter, half-year or year for
which the bill is rendered. Any bill for a month, quarter or half-year may be
rendered on an estimated basis, in which event the estimate shall be the actual
cost of the item for the next year preceding increased by Landlord's good faith
estimate of what the increase for the current year shall be. Any estimated bill
need not include all of the items mentioned in Section X(b). Any annual bill
shall be rendered on the basis of actual costs only. If Landlord shall render a
monthly, quarterly or semi-annual bill on account of any calendar year, then
within one hundred eighty (180) days after the close of such calendar year,
Landlord shall render an annual bill for such year which annual bill shall make
all adjustments as may be necessary to reflect actual changes during that year
including, without limitation, any refund as may be due to Tenant. All bills for
the cost escalation portion of the Rent shall be due within thirty (30) days
after receipt.

                  (7) If the Commencement Date or the Termination Date of the
Lease occurs in the middle of a Computation Year, Tenant shall be liable for
only that portion of the Operating Cost Excess in respect of such Computation
Year represented by a fraction, the numerator of which is the number of days of
the herein term which falls within the Computation Year, and the denominator of
which is three hundred sixty-five (365).

                  (8) In the event of any taking of the Building or the land
upon which it stands under circumstances whereby this Lease shall not terminate
under the provisions of Section XVI, the Operating Cost Base shall be adjusted
pro-rata to reflect the proportion of the Premises and/or Property remaining
after such taking.

                  (9) Any obligation under this Section X(b) of Tenant which
shall not have been paid at the expiration of the term of this Lease shall
survive such obligation and shall be paid when and as the amount of same shall
be determined to be due.

         Provided Tenant shall have paid any amounts due under any Operating
Cost Excess Statement and Tax Excess Statement, within sixty (60) days after
receipt of each Landlord's Operating Cost Excess Statement and Tax Excess
Statement, Tenant or its agent shall have the right to examine Landlord's
records relating to the Operating Expenses and Taxes (including the results of
any Survey provided in Section XI(c)) and the calculation of Tenant's
Proportionate Share thereof. Landlord shall make all its records relating to the
calculation of Operating Expenses and Taxes (including the results of any Survey
provided in Section XI(c)) available to Tenant or its agent at reasonable times
at the address of Landlord. Tenant may take exception to such matters included
in Operating Expenses, Taxes (including the results of any Survey provided in
Section XI(c)) or Tenant's Proportionate Share thereof as are not properly
included therein pursuant to the terms of this Lease and Landlord shall, within
30 days after written demand, refund Tenant the amounts which Tenant has been
improperly charged unless Landlord in good faith contests such amount. If
Landlord in good faith contests such amount, then either

                                      -14-
<PAGE>

Landlord or Tenant shall have the right, upon notice to the other, to initiate
the following dispute resolution procedure: Tenant and Landlord shall endeavor
to reconcile such dispute within thirty (30) days after the written notice from
Tenant. If the parties are unable to resolve such dispute, they shall jointly
select a third, independent party who shall make a final and binding decision
within thirty (30) days after being selected. The third party's fee shall be
paid by the party against whom such decision is rendered.

         SECTION XI. REMOVAL OF GOODS AND TENANT'S REPAIRS. At the expiration or
sooner termination of this Lease, Tenant will remove its goods and effects
(except as elsewhere provided herein) and will peaceably yield up to the
Landlord the Premises in as good order and condition as when delivered to it,
excepting ordinary wear and tear (which shall not be deemed to include holes in
walls or floors or special wiring caused by installation of Tenant's fixtures or
equipment), repairs required to be made by Landlord and damage by fire or
unavoidable casualty and the exercise of eminent domain powers.

         The Tenant shall be responsible for all damages or injury to the
Premises, fixtures, appurtenances and equipment of Landlord, and to the Building
and the Property, caused by Tenant's installation or removal of furniture,
fixtures or equipment.

         SECTION XII. SALES TAX. In the event that any sales tax shall be levied
by the Commonwealth of Massachusetts, or the Town of Stoneham, or any other
authority having jurisdiction, upon the Rent and/or the Additional Rent received
by Landlord from Tenant, the exact amount of such tax shall be paid by Tenant to
Landlord at the same time each installment of Rent and/or Additional Rent is
paid to the Landlord.

         SECTION XIII. IMPROVEMENTS AND ALTERATIONS. The Tenant may place such
partitions, fixtures, (including light fixtures), personal property, machinery
and the like (subject to Section VII) in the Premises and may make, at its own
expense, such improvements and alterations as have the prior written approval of
Landlord in each instance, which approval shall not be unreasonably withheld,
conditioned or delayed. All work done by Tenant in the Premises shall be done in
accordance with all zoning, building, fire and other codes applicable thereto.
All fixtures, equipment (except Tenant's trade fixtures and equipment),
improvements and appurtenances paid for by Tenant and attached to or built into
the Premises prior to or during the term shall be and remain part of the
Premises as of the end of the term unless specifically excluded elsewhere in
this Lease. In the case of damage or destruction of such items during the term,
Tenant shall have the right to recover its loss from any insurance company with
which it has insured the same, notwithstanding that any of such things might be
considered part of the Premises at the end of the term. At the option of
Landlord, Tenant shall remove any or all of such fixtures, equipment,
improvements and alterations at the end of the term; provided that Landlord
notifies Tenant in writing at the time Landlord approves of the installation of
any such fixtures, equipment, improvement and alterations that Landlord wishes
to exercise such option. Landlord may not require removal of pipes, wires and
the like from the walls, ceilings or floors, provided that the Tenant properly
cuts, caps and disconnects such pipes and wires and seals them off in a safe and
lawful manner flush with the applicable wall, floor or ceiling and redecorates
the area consistent with the remainder of the Premises. Tenant shall be
responsible for any

                                      -15-
<PAGE>

damage to the Building caused by the malfunction of its equipment or the removal
of its property as aforesaid, subject to Section XXXIII.

         SECTION XIV. INSPECTION. The Landlord and any mortgagee of the Building
or of the Building and Property, or of Landlord's interest therein, and their
representatives shall have the right during business hours and upon 24 hour
advance notice, except in the event of an emergency, to enter the Premises to
inspect the same and to make repairs or replacements therein as required by this
Lease and to introduce conduits and pipes or ducts within walls then existing in
the Premises and above ceilings then existing in the Premises; provided,
however, that the Landlord shall use reasonable effort not to unduly disturb the
Tenant's use and occupancy.

         SECTION XV. CASUALTY. If the Premises, the Building or Property shall
be damaged or destroyed by fire or other casualty insurable under standard
coverage insurance to the extent of less than twenty-five percent (25%) of the
full replacement cost thereof at the time of such damage or destruction,
Landlord shall, except as otherwise provided herein, repair and/or rebuild the
same with reasonable diligence, but Landlord's obligation hereunder shall be
limited to restoring the Premises to the condition of the Premises immediately
prior to the date of such casualty and shall also be subject to zoning and
building laws then applicable to the Premises. Landlord's obligation hereunder
shall be limited to the proceeds received by Landlord (net of any amounts
required to be paid to Landlord's mortgagee) plus any deductible under the
insurance policy which is allocable to the Premises and Landlord shall not be
obligated to commence such repairs and/or rebuilding until such insurance
proceeds are released to Landlord. Tenant shall repair or restore with due
diligence all trade fixtures, equipment and other installations theretofore
installed by Tenant to the extent of Tenant's obligations as set forth in
EXHIBIT B and damaged or destroyed by such fire or casualty. If the Premises or
the Building shall be damaged or destroyed to the extent of twenty-five percent
(25%) or more of the full replacement cost thereof at the time of such damage or
destruction, or shall be damaged or destroyed as a result of a risk which is not
covered by insurance, or shall be damaged or destroyed to any extent by any
cause in the last two (2) years of the then current term of this Lease (unless
Tenant shall have exercised prior to the date of said fire or other casualty any
remaining option to extend the term of this Lease), or if the Property (whether
or not including the Premises or the Building) should be damaged or destroyed to
the extent of twenty-five percent (25%) or more of the full replacement cost
thereof at the time of such damage or destruction, the Landlord may at its sole
election restore or rebuild the Premises, the Building or the Property, as the
case may be, or terminate this Lease.

         In any instance where Landlord shall have an election to terminate this
Lease by reason of such damage or destruction, it shall give Tenant notice of
its election within sixty (60) days after such damage or destruction, and in
such event, if Landlord shall elect to restore or rebuild the Premises, Building
or Property as applicable, Landlord shall proceed to do so and Tenant shall
replace or restore with due diligence all trade fixtures, equipment and other
installations theretofore installed by Tenant and damaged or destroyed by such
fire or other casualty. Landlord's obligation hereunder shall be to restore or
rebuild the Premises to the condition of the Premises immediately prior to the
date of such casualty and shall also be subject to zoning and building laws then
applicable to the Premises. Landlord's obligation hereunder shall be limited

                                      -16-
<PAGE>

to the proceeds received and retained by Landlord (net of any amounts required
to be paid to Landlord's mortgagee) under the insurance policy which is
allocable to the Premises, and Landlord shall not be obligated to commence such
repairs and/or rebuilding until such insurance proceeds are released to
Landlord. Tenant shall, during any period of reconstruction or repair of the
Premises, the Building and/or of the Property, continue the operation of its
business in the Premises to the extent reasonably practicable. If the Premises
or any part thereof, or the Building shall be damaged or destroyed by fire or
other casualty (irrespective of the time when such damage or destruction shall
occur, and irrespective of whether or not Landlord shall be insured against the
perils causing same) and if as a result thereof the Premises shall be rendered
untenantable to an extent which would reasonably require the Tenant to curtail a
part of its business operation, then a just proportion of the Rent reserved
hereunder shall be suspended or abated according to the extent to which Tenant
may be reasonably required to discontinue its business in the Premises until the
work of restoration to be done by Landlord as aforesaid shall be substantially
completed.

         Notwithstanding anything herein to the contrary, in the event that (i)
any portion of the Premises, or (ii) such portion of the Property as shall
materially adversely interfere with Tenant's use and occupancy of the Premises,
is damaged or destroyed and Landlord does not elect to terminate this Lease as
provided herein, and in the further event that Landlord has not substantially
completed the repair and restoration thereof within two hundred seventy (270)
days following the date of the damage or destruction for any reason whatsoever,
then Tenant shall have the right to terminate this Lease upon ninety (90) days'
written notice to Landlord given anytime following said two hundred seventy
(270) day period, unless such repair and restoration is substantially completed
prior the effective date specified in such notice.

         SECTION XVI. EMINENT DOMAIN. If the whole of the Premises, the
Building, or the Property shall be taken by condemnation or rights of eminent
domain (the words "condemnation" and "eminent domain" as used herein to include
purchase in lieu thereof) hereinafter collectively referred to as "taking", then
the term hereof shall cease as of the date of the vesting of title or as of the
day possession shall be taken thereunder, whichever is earlier. If twenty-five
percent (25%) or more of the Property shall be taken (whether or not the
Building or the Premises is within said twenty-five percent (25%) or if
twenty-five percent (25%) or more of the Premises or twenty-five percent (25%)
or more of the Building are a part shall be taken, Landlord shall be entitled to
terminate this Lease effective as of the day of vesting of title or as of the
day possession shall be taken thereunder, whichever Landlord shall elect, by
giving Tenant notice of its election within sixty (60) days of such vesting of
title or taking of possession; but if Landlord does not elect to so terminate
this Lease, it shall with due diligence restore the Premises and/or the Building
and/or the Property to an architectural unit as nearly like its condition prior
to such taking as shall be practical. If forty percent (40%) or more of the
Premises shall be taken, or if twenty-five (25%) or more of the Building of
which the Premises are a part shall be taken, including in such taking some
portion of the Premises, Tenant shall be entitled to terminate this Lease by
giving notice to Landlord to that effect within sixty (60) days following the
taking of possession of the Premises, in which event this Lease and the term
hereof shall cease and terminate as of the end of the calendar month in which
such notice shall be given.

                                      -17-
<PAGE>

If this Lease is not terminated as hereinbefore provided, either by Landlord or
Tenant, all of the provisions hereof shall continue in effect, but in case there
shall be a reduction of the floor area of the Premises by reason of such taking,
the Rent and Additional Rent shall be equitably abated to the extent of the
reduction of the floor area of the Premises from the time possession shall be
taken for the balance of the term.

         During the restoration work to be done by Landlord, if any, a just
proportion of the Rent and Additional Rent herein reserved shall be suspended or
abated according to the extent that Tenant may be reasonably required to
discontinue its business in the Premises until the work shall be completed.
Tenant shall during any period of such work continue the operation of the
business in the Premises to the extent reasonably practicable. In the event of
restoration, Landlord's obligation to restore shall be limited to the
obligations of Landlord in connection with the condition of the Premises as of
the Commencement Date and limited to the extent of the damages awarded for the
taking and released to Landlord (net of any amounts required to be paid to
Landlord's mortgagee). Landlord's obligations shall be subject to zoning and
building laws then applicable to the Premises. Tenant shall repair or restore
all Tenant trade fixtures or equipment and other installations theretofore
installed by Tenant to the extent of recovery by Tenant in condemnation
proceedings. All damages awarded for any taking, whether for the whole or a part
of the Premises, the Building, or the balance of the Property, or otherwise,
shall belong to and be the property of Landlord whether such damages shall be
awarded as compensation for diminution in value to the leasehold or to any fee
or otherwise; provided, however, that Tenant shall be entitled to receive and
retain any amounts which may be specifically awarded to it by reason of the loss
of its trade fixtures or furniture. Tenant shall have the right to prosecute any
claim for its relocation or moving expenses.

         SECTION XVII. INDEMNIFICATION. Tenant shall save Landlord harmless, and
will exonerate and indemnify Landlord from and against any and all claims,
liabilities or penalties asserted by or on behalf of any person, firm or public
authority:

         (a) on account of or based upon any injury to person, or loss of or
damage to property, sustained or occurring on the Premises on account of or
based upon the act, omission, fault, or neglect of Tenant, its servants, agents,
employees, licensees, invitees and guests;

         (b) on account of or based upon any injury to person or loss of or
damage to property, sustained or occurring elsewhere (other than on the
Premises) in or about the Building (and, in particular, without limiting the
generality of the foregoing on or about the elevators, stairways, public
corridors, sidewalks, concourses, arcades, approaches, areaways, roof, parking
areas, or other appurtenances and facilities used in connection with the
Building or Premises) arising out of the negligence or willful misconduct by the
Tenant or by any person claiming by, through or under Tenant, except to the
extent caused by or resulting from Landlord's negligence, or willful misconduct
or that of Landlord's, or its agents, employees or contractors under its direct
control, and in addition to and not in limitation of either of the foregoing
subdivisions (a) or (b); and

         (c) on account of or based upon (including monies due on account of)
any work or things whatsoever done (other than by Landlord or its contractors,
or agents or employees of either) on the Premises during the term of this Lease
and during the period of time, if any, prior to the Commencement Date that
Tenant may have been given access to the Premises; and, in

                                      -18-
<PAGE>

respect of any of the foregoing, from and against all costs, expenses (including
reasonable attorney's fees), and liabilities incurred in or in connection with
any such claim, or any action or proceeding brought thereon; and in case any
action or proceeding be brought against Landlord by reason of any such claim,
Tenant, upon notice from Landlord, shall, at Tenant's expense, resist or defend
such action or proceeding and employ counsel therefor reasonably satisfactory to
Landlord, it being agreed that such counsel as may act for insurance
underwriters of Tenant engaged in such defense shall be deemed satisfactory.

         Notwithstanding the foregoing, the indemnity set forth in subsection
(a),(b) and (c) above shall not apply in the event that the injury to person or
loss of or damage to property is sustained or occurs elsewhere (other than on
the Premises) in or about the Building and the Property (and, in particular,
without limiting the generality of the foregoing on or about the elevators,
stairways, public corridors, sidewalks, concourses, arcades, approaches,
areaways, roof, parking areas, or other appurtenances and facilities used in
connection with the Building or Premises) and arises out of or is caused by the
negligence, willful acts or omissions of the Landlord, or its agents,
contractors or employees not acting under separate contract to Tenant for
specific work.

         SECTION XVIII. PROPERTY OF TENANT. In addition to and not in limitation
of other provisions of this Lease, Tenant covenants and agrees that all of its
merchandise, furniture and property of every kind, nature and description which
may be in or upon the Premises, Building, or Property in the public corridors,
or on the sidewalks, areaways, and approaches thereto, or parking areas during
the term hereof, shall be at the sole risk and hazard of Tenant, and that if the
whole or any part thereof shall be damaged, destroyed, stolen or removed by any
cause whatsoever, no part of said damage or loss shall be charged to or borne by
Landlord, unless caused by the negligence or willful misconduct of Landlord or
its employees, contractors or agents, subject to the rights of subrogation
herein. Tenant shall, at Tenant's expense, obtain and keep in force "all risk"
property insurance covering Tenant against damage to or loss of any personal
property, fixtures and equipment of Tenant, and provide for waiver of
subrogation by Tenant's insurer against Landlord and coverage for the full
replacement cost of such property.

         SECTION XIX. INJURY AND DAMAGE. Landlord shall not be liable for any
injury or damage to persons or property resulting from fire, explosion, falling
plaster, steam, gas, electricity, electrical disturbance, water, rain or snow,
or leaks from any part of the Building or parking area, or from the pipes,
appliances, or plumbing works or from the roof, street or subsurface or from any
other place or from dampness or by any other cause of whatever nature, whether
caused by other tenants or persons in the Building, or on the Property, or in
any parking area or caused by operations in construction of any private, public
or quasi-public work unless caused by the negligence or willful misconduct of
Landlord or employees, contractors or agents; nor shall Landlord be liable for
any latent defect in the Premises, in the Building, or on the Property, except
to the extent Landlord had prior written notice of such condition and failed to
reasonably attempt, in a reasonable period of time to cure said condition unless
caused by the negligence or willful misconduct of Landlord or employees,
contractors or agents.

         SECTION XX. ASSIGNMENT, MORTGAGING, AND SUBLETTING. Tenant covenants
and agrees that neither this Lease nor the term and estate hereby granted, nor
any interest herein or therein, will be assigned, mortgaged, pledged, encumbered
or otherwise

                                      -19-
<PAGE>

transferred, and that neither the Premises, nor any part thereof will be
encumbered in any manner by reason of any act or omission on the part of Tenant,
or used or occupied, or utilized for desk space or for mailing privileges, by
anyone other than Tenant, or for any use or purpose other than as stated herein,
or be sublet or offered or advertised for subletting without the prior notice to
Landlord. Without in any manner limiting the generality of the foregoing,
several of the considerations which Landlord may include in its determination
are the quality and character of the business of the proposed assignee or
subtenant, the anticipated impact of the business of the proposed assignee or
subtenant on the reputation and operation of the Building, and the credit
worthiness of the proposed assignee or subtenant. Notwithstanding anything
contained herein to the contrary, Tenant shall have no right to (i) assign this
Lease or sublet any interest hereunder to any person or entity with whom
Landlord is then negotiating for the rental of other space in the Building, or
(ii) offer any proposed assignment or sublet premises, and Landlord shall not be
deemed to unreasonably withhold its consent to assign or sublet such premises at
a rental rate which is less than the Rent the Tenant is currently paying for the
Premises, when, in Landlord's reasonable determination, and subject to Tenant's
satisfactory review, the proposed assignment or sublet premises would compete
with space then being offered by Landlord in the Building at the same time which
is comparable to the space being offered by the Tenant. Not in limitation of the
foregoing, Tenant's request for Landlord's consent to subletting or assignment
shall be submitted in writing, and Landlord shall respond to such request within
thirty (30) days of receipt thereof, and Landlord's consent to an assignment or
subletting shall be conditioned upon the deletion of any and all rights of
Tenant of expansion, contraction, first offer and term extension and Landlord's
consent to a sublet, if granted, shall obligate Tenant to pay to Landlord, in
addition to the Rent and Additional Rent required hereunder, fifty percent (50%)
of any and all "profits" derived from such sublet. For the purposes hereof,
"profits" shall mean all monies and other consideration received by Tenant from
the subtenant, less any Rent paid by Tenant to Landlord allocable to the portion
of the Premises so sublet, and less the total of customary transaction costs
incurred by Tenant with respect to such sublet for brokerage and leasehold
improvements amortized over the term of such sublease. The foregoing provisions
shall not apply to the transfer of this Lease to an Assignee. Tenant agrees to
reimburse Landlord for reasonable legal fees and any other reasonable expenses
and costs incurred by Landlord in connection with any proposed assignment or
subletting.

         Landlord's consent shall be granted only if the assignee, subtenant or
sublessee, shall promptly execute, acknowledge, and deliver to Landlord an
agreement in form and substance reasonably satisfactory to Landlord whereby the
assignee, subtenant or sublessee shall agree to be bound by and upon the
covenants, agreements, terms, provisions and conditions set forth in this Lease,
to the extent incorporated into any sublease. If Tenant shall sublet the
Premises, having first obtained Landlord's consent, at a rental in excess of the
Rent and Additional Rent due and payable by Tenant under the provisions of this
Lease, such excess Rent and Additional Rent shall be equally divided equally
between Landlord and Tenant, net of reasonable expenses related to said sublease
paid by Tenant, it being agreed, however, that Landlord shall not be responsible
for any deficiency if Tenant shall sublet the Premises at a rental less than
that provided for herein. Further, it is agreed that in lieu of withholding or
granting its consent to an

                                      -20-
<PAGE>

assignment or sublease of all of the Premises Landlord may, within thirty (30)
days of receipt of a request for consent from Tenant, cancel this Lease as to
the entire Premises. If Landlord shall elect to cancel this Lease as to the
Premises, it shall give Tenant written notice of its election, which notice
shall set forth a "termination date" which shall be not less than sixty (60) or
more than one hundred twenty (120) days from the receipt by Landlord of Tenant's
request to assign or sublet, and on that "termination date" Tenant shall
surrender the Premises in accordance with the provisions of this Lease relating
to the surrender of the Premises as the expiration of the term of this Lease. It
is hereby expressly understood and agreed, however, if Tenant is a corporation,
that the assignment, or transfer of this Lease, and the term and estate granted,
to any corporation, entity or individual into which Tenant is merged or with
which Tenant is consolidated or which acquires all or substantially all of
Tenant's assets, which corporation shall have a net worth at least equal to that
of Tenant immediately prior to such merger or consolidation (such corporation
being hereinafter called "ASSIGNEE"), without the prior written consent of
Landlord shall not be deemed to be prohibited hereby, if, and upon the express
condition that, Assignee and Tenant shall promptly execute, acknowledge, and
deliver to Landlord an agreement in form and substance reasonably satisfactory
to Landlord whereby Assignee shall agree to be bound by and upon the covenants,
agreements, terms, provisions and conditions set forth in this Lease on the part
of Tenant to be performed and whereby Assignee shall expressly agree that the
provisions of this Section XX shall, notwithstanding such assignment transfer,
continue to be binding upon it with respect to all future assignments and
transfers. The listing of any name other than that of Tenant, whether on the
doors of the Premises or on the Building directory, or otherwise, shall not
operate to vest any right or interest in this Lease or in the Premises or be
deemed to be the written consent of Landlord mentioned in this Section XX, it
being expressly understood that such listing is a privilege extended by Landlord
revocable at will by written notice to Tenant.

         If this Lease is assigned, or if the Premises or any part thereof is
sublet or occupied by anybody other than Tenant, Landlord may, after default by
Tenant, collect Rent and/or Additional Rent from the Assignee, subtenant or
occupant, and apply the net amount collected to the Rent herein reserved, but no
such assignment, subletting, occupancy or collection shall be deemed a waiver of
this covenant, or the acceptance of the Assignee, subtenant or occupant as a
tenant, or a release of Tenant from the further performance by Tenant of
covenants on the part of Tenant herein contained. The consent by Landlord to an
assignment or subletting shall not in any way be construed to relieve Tenant
from obtaining the express consent in writing of Landlord to any further
assignment or subletting. No assignment, subletting or use of the Premises by an
affiliate of Tenant shall affect the purpose for which the Premises may be used
stated in Section II. Notwithstanding any permitted assignment or subletting,
Tenant shall at all times remain directly, primarily and fully responsible and
liable for the payment of all sums payable under the Lease and for compliance
with all the obligations of Tenant under the Lease.

         SECTION XXI. SIGNS, BLINDS AND WINDOW TREATMENTS. No signs or blinds
may be put on or in any window by Tenant. Tenant may install its own window
treatment, provided that the same shall not in any way interfere with the
Building standard blinds or be visible from the exterior of the Building. Any
signs or letters in the public corridors or on the doors or on monument signage
must be submitted to Landlord for written approval (which

                                      -21-
<PAGE>

approval shall not be unreasonably withheld, conditioned or delayed provided
such signage is consistent with what currently exists in the Building) before
installation, which installation shall be at the sole expense of Tenant. Tenant
shall have the right to building standard signage in the lobby directory and on
the existing monument sign at the entrance to the Property, subject to
reasonable consent of Landlord and the initial cost of such signage shall be at
Landlord's expense. Any subsequent changes to the signage shall be at Tenant's
expense.

         SECTION XXII. INSURANCE COMPLIANCE. Tenant will not do or omit to do or
keep anything in, upon or about the Premises which may prevent the obtaining of
any fire, liability or other insurance upon or written in connection with the
Premises or the Building or the Property or which may make any such insurance
void or voidable, or which may create any extra premiums or increase the rate of
any such insurance over that normally applicable to office buildings unless the
Tenant pays such extra or increased premiums.

         SECTION XXIII. INFLAMMABLES, ODORS. Tenant shall not bring or permit to
be brought or kept in or on the Premises or elsewhere in the Building, any
inflammable, combustible or explosive fluids, material, chemical or substance
(other than small quantities of industrial solvents used in the normal course of
cleaning and maintenance), or cause or permit any odors of cooking or other
processes, or any unusual or other objectionable odors to emanate from or
permeate the Premises.

         SECTION XXIV. DEFAULT. Any one of the following shall be deemed to be
an "EVENT OF DEFAULT":

         (a) Failure on the part of Tenant to pay Rent, Additional Rent or other
charges for which provision is made herein on or before the date on which the
same become due and payable and such failure continues for ten (10) days (the
"MONETARY NOTICE AND CURE PERIOD") after Landlord has sent to Tenant notice of
such default. However, if: (i) Landlord shall have sent to Tenant a notice of
default, even though the same shall have been cured and this Lease not
terminated; and (ii) during the twelve (12) month period next following the date
on which said notice of default has been sent by Landlord to Tenant, Tenant
thereafter shall have defaulted twice in any monetary obligation pursuant to the
Lease, the same shall automatically be deemed to be an Event of Default upon
Landlord giving Tenant written notice thereof, and there shall be no monetary
notice and cure period.

         (b) Failure on the part of Tenant to comply with any term, condition,
or requirement of this Lease and failure of Tenant to cure the same within
thirty (30) days (the "NON-MONETARY NOTICE AND CURE PERIOD") following notice
from Landlord to Tenant of a non-monetary default, unless any such cure cannot
reasonably be made within such thirty (30) days period, then Tenant shall have a
reasonable period of time to effectuate a cure provided Tenant promptly
commences such cure upon receipt of notice of default and diligently prosecutes
such cure to completion. Notwithstanding the thirty (30) day non-monetary notice
and cure period (or such period as may be required to cure) provided in the
preceding sentence, Tenant shall be obligated to immediately commence, and use
best efforts to complete as soon as possible, the curing of such default.

         (c) Failure on the part of Tenant to comply with Maximum Parking Lot
Usage or Maximum Occupancy requirements as described in Section II herein and
failure of Tenant to

                                      -22-
<PAGE>

cure the same within twenty-four (24) hours following notice from Landlord to
Tenant of such default. However, if: (i) Landlord shall have sent to Tenant a
notice of such default, even though the same shall have been cured and this
Lease not terminated; and (ii) during the twelve (12) month period next
following the date on which said notice of default has been sent by Landlord to
Tenant, Tenant thereafter shall default in its obligations to comply with the
Maximum Parking Lot Usage or Maximum Occupancy, the same shall automatically be
deemed to be an Event of Default upon Landlord giving Tenant written notice
thereof, and there shall be no twenty-four (24) hour cure period.

         (d) The commencement of any of the following proceedings, which are not
dismissed within sixty (60) days after filing: (i) the estate hereby created
being taken on execution or by other process of law; (ii) Tenant being
judicially declared bankrupt or insolvent according to law; (iii) an assignment
being made of the property of Tenant for the benefit of creditors; (iv) a
receiver, guardian, conservator, trustee in involuntary bankruptcy or other
similar officer being appointed to take charge of all or any substantial part of
Tenant's property by a court of competent jurisdiction; or (v) a petition being
filed for the reorganization of Tenant under any provisions of the Bankruptcy
Act now or hereafter enacted.

         (e) Tenant filing a petition for reorganization or for rearrangement
under any provisions of the United States Bankruptcy Code now or hereafter
enacted, and providing a plan for a debtor to settle, satisfy or to extend the
time for the payment of debts.

         If an Event of Default shall occur, then in addition to any other
remedy Landlord may have at law or equity, Landlord may (i) apply the Security
Deposit, if any, specified in Section XLIII toward the satisfaction of such
Event of Default without waiving any of Landlord's other rights hereunder, (ii)
cure Tenant's Event of Default at Tenant's cost and expense, and/or (iii)
Landlord may lawfully enter the Premises or any part thereof and repossess the
same as the former estate of the Landlord and expel the Tenant and those
claiming under the Tenant without being deemed guilty of any manner of trespass.

         In the case of Lease termination, whether as aforesaid or otherwise,
the Tenant covenants that it will indemnify the Landlord against all losses
Landlord may incur by reason of such termination. Upon such termination, all of
Tenant's monetary obligations under the Lease shall immediately become due and
payable to Landlord, and the Tenant will immediately be liable for, and pay to
Landlord as damages, all such losses, including without limitation; all Rent,
Additional Rent and other charges due pursuant to the Lease up until the normal
expiration of the Lease term (had the Lease not been terminated in accordance
herewith) (including escalations projected on the basis of experience under the
Lease), together with all costs Landlord may incur in obtaining possession of,
or in reletting the Premises (including without limitation reasonable attorneys
fees, brokerage commissions, prospective tenant improvements, alterations,
repairs and decorations to the Premises as Landlord in its sole judgment
considers advisable or necessary to relet the same), together with Tenant's
proportionate share of any permitted unamortized capital improvements incurred
during the Lease term, and any monies owed by Tenant to Landlord for any tenant
improvements to the Premises in accordance with the Lease, together with
interest at the rate of 1.5% per month until said monies are paid in full.

                                      -23-
<PAGE>

         Landlord shall use reasonable efforts to relet the Premises on such
terms and conditions as Landlord in its sole discretion may determine (including
a term different from the term of the Lease, rental concessions, and alterations
to, and improvement of, the Premises), and otherwise mitigate its damages
hereunder. However, Landlord shall not be obligated to relet the Premises at
below market rates, nor shall Landlord be obligated to relet the Premises before
leasing other portions of the Building. Landlord shall not be liable for, nor
shall Tenant's obligations hereunder be diminished because of, Landlord's
failure to relet the Premises or to collect rent due for such reletting. In the
event of reletting, Landlord shall have no liability to account to Tenant for
any excess in proceeds received from such reletting.

         SECTION XXV. SUBORDINATION AND ESTOPPEL. This Lease shall be subject
and subordinate in all respects to all mortgages which may now or hereafter be
placed on or affect the real property of which the Premises are a part, or
Landlord's interest or estate therein, and to each advance made and/or hereafter
to be made under any such mortgages, and to all renewals, modifications,
consolidations, replacements and extensions thereof and all substitutions
therefor. This Section XXV shall be self-operative and no further instrument of
subordination shall be required. Notwithstanding the generality of the foregoing
provisions of this Section XXV, Tenant agrees that any such mortgagee shall have
the right at any time to subordinate any such mortgages or other instruments of
security to this Lease on such terms and subject to such conditions as such
mortgagee may deem appropriate in its discretion. Tenant further covenants and
agrees upon demand by Landlord's mortgagee at any time, before or after the
institution of any proceedings for the foreclosure of any such mortgages or
other instruments of security, or sale of the Building pursuant to any such
mortgages or other instruments of security (which agreement shall survive any
such foreclosure sale), to attorn to such mortgagee or such purchaser upon any
such sale and to recognize such purchaser as Landlord under this Lease, provided
that Tenant's possession shall not be disturbed except under the terms of this
Lease, and further agrees to execute any and all documents as such mortgagee may
require to confirm such attornment and provided further, that subordination of
this Lease and Tenant's rights hereunder shall be conditioned upon the holder of
any future mortgage agreeing, in a duly executed writing in recordable form
reasonably acceptable to Tenant, that this Lease and Tenant's rights hereunder
shall not be divested or in any way affected or disturbed by any foreclosure or
other exercise of rights or remedies under such mortgage, so long as there
exists no Event of Default under the terms and provisions of this Lease.
Landlord agrees to use all reasonable efforts to obtain a subordination and
non-disturbance agreement from the current mortgagee in favor of the Tenant, For
the purposes hereof, the term "all reasonable efforts" shall not include the
payment of any such sum of money or the consent to less favorable terms and
conditions with respect to the obligations or indebtedness secured or created by
such mortgage. In the event Tenant fails to deliver and execute such documents
within ten (10) days after demand in writing, Tenant does hereby make,
constitute and irrevocably appoints Landlord as attorney in fact to execute said
documents.

         Tenant shall, from time to time, within twenty (20) days after request
from Landlord, or from any mortgagee of Landlord, execute, acknowledge and
deliver in recordable form an estoppel certificate ("ESTOPPEL CERTIFICATE")
certifying, to the extent true, that this Lease is in

                                      -24-
<PAGE>

full force and effect and unmodified (or, if there have been modifications, that
the same is in full force and effect as modified and stating the modifications);
that the term has commenced and the full amount of the Rent and Additional Rent
then accruing thereunder the dates to which the Rent has been paid; that Tenant
has accepted possession of the Premises and that any improvements required by
the terms of this Lease to be made by Landlord have been completed to the
satisfaction of Tenant; the amount, if any, that Tenant has paid to Landlord as
a security deposit; that no Rent under this Lease has been paid more than thirty
(30) days in advance of its due date; that the address for notices to be sent to
Tenant is as set forth in this Lease (or has been changed by notice duly given
and is as set forth in the Estoppel Certificate); that Tenant, as of the date of
such Estoppel Certificate, has no charge, lien, or claim of offset under this
Lease or otherwise against Rent or Additional Rent due or to become due
hereunder; that, to the knowledge of Tenant, Landlord is not then in default
under this Lease; and such other matters as may be reasonably requested by
Landlord or any mortgagee of Landlord. Any Estoppel Certificate may be relied
upon by Landlord, any successor of Landlord, any mortgagees of Landlord or any
prospective purchaser of the Building. In addition, Landlord and Tenant will
execute a mutually acceptable short form notice of lease prepared by Tenant.

Landlord. The failure of Landlord to seek redress for violation of, or to insist
upon the strict performance of this Lease, or any of the rules and regulations
set forth in this Lease or hereafter adopted by Landlord, shall not constitute a

a violation from having all force and effect of an original violation. The
receipt by Landlord of Rent or Additional Rent with knowledge of the breach of
any provision of this Lease shall not be deemed a waiver of such breach. No
payment by Tenant or receipt by Landlord of a lesser amount than the monthly
Rent or Additional Rent herein stipulated shall be deemed to be other than on
account, nor shall any endorsement or statement on any check, nor any letter
accompanying any check or payment as Rent or Additional Rent be deemed an accord
and satisfaction, and Landlord may accept such check or payment without
prejudice to Landlord's right to recover the balance of such Rent or Additional
Rent or pursue any other remedy in this Lease provided.

construed as a tenancy at sufferance only, provided that all the terms of this
Lease shall apply except that the Rent set forth in Section IV shall be
calculated at a daily rate equal to one hundred fifty percent (150%) of the
daily Rent reserved in said Section IV. Nothing contained in this Section XXXIX
shall be construed as Landlord's consent to Tenant holding over.

a matter of convenience and for reference and in no way define, limit or
describe the scope of this Lease nor the intent of any provisions hereof.

the Letter of Credit in the amounts required hereunder notwithstanding any prior
presentation and draw thereon.

         The Letter of Credit must at all times be an "irrevocable clean"
commercial Letter of Credit in the amount required by this Lease and payable
through a bank, acceptable to Landlord in Landlord's reasonable discretion. In
addition, the Letter of Credit shall be payable solely to the benefit of the
Landlord from time to time under this Lease and shall be automatically renewable
and, upon the direction of Landlord, transferable to and payable for the benefit
of any successor Landlord under the Lease. The Letter of Credit shall be and
remain presentable and payable for the time period beginning on the date of this
Lease through and including the date

                                      -30-

which is the last to occur of (i) the date which is 60 days after the last day
of the Term of this Lease or (ii) the date which is 60 days after the date of
delivery of the entire Premises to Landlord in accordance with the terms and
provisions of this Lease or (iii) 60 days after the last of Tenant's monetary
obligations to Landlord under this Lease have been satisfied in full. Tenant
shall bear all costs and expenses in connection with procuring the Letter of
Credit and maintaining it in full force and effect for the time periods required
hereunder. In the event of a sale or other transfer of the Building, Tenant
shall, at its sole cost and expense, cause the Letter of Credit, in the form
required hereunder, to be issued to and for the benefit of such transferee or
purchaser, as designated by Landlord.

         The Landlord from time to time under this Lease, shall be entitled to
receive 60 days prior written notice of any cancellation of the Letter of Credit
for any reason and the Letter of Credit shall not be cancelable unless and until
Landlord shall have received such sixty (60) day advance written notice. Upon
(i) receiving notice of cancellation of the Letter of Credit or (ii) failure of
Tenant to deliver to Landlord a substitute Letter of Credit on or before the
date which is 30 days prior any renewal date and whether or not Tenant shall
then be in default in the payment, performance or observance of any term,
covenant or provision of this Lease, Landlord shall be entitled to present, draw
upon and retain the entire amount of the Letter of Credit and upon so doing,
Landlord shall be entitled to hold, apply and retain the proceeds of such
payment as if it were a Cash Security Deposit under this Lease to be applied
against Defaults of Tenant from time to time arising under this Lease. Provided
that Tenant shall provide Landlord with a replacement Letter of Credit, Landlord
shall refund any such cash being held as a security deposit to Tenant.

         Landlord may apply all or any portion of the security deposit to any
damage to the Premises or to the restoration thereof or to any Rent or
Additional Rent which may be due from Tenant to Landlord. In the event that
Landlord shall so apply all or any portion of the said security deposit, Tenant
shall immediately upon notice, restore the same to its full amount. All or any
portion of the security deposit remaining at the expiration or other termination
of this Lease which has not been so applied shall be returned to Tenant, as set
forth above.

         SECTION XLIV. LANDLORD'S RIGHT TO PERFORM FOR TENANT. Landlord shall
have the right, but shall not be required, to pay such sums and do any act,
whether the same requires the expenditures of monies or not, which may be
necessary or appropriate by reason of failure or neglect of the Tenant after
expiration of any applicable notice and cure periods to perform any of the
provisions of this Lease, and in the event of the exercise of such right by the
Landlord, the Tenant agrees to pay to the Landlord forthwith upon demand the
cost of performing the same, plus interest at one and one-half percent (1 1/2%)
per month of such cost; and if Tenant shall default in such payment after
expiration of any applicable notice and cure periods, the Landlord shall have
the same rights and remedies as the Landlord has hereunder for the failure of
the Tenant to pay the Rent or Additional Rent. Landlord may exercise the
foregoing rights without waiving any other of its rights or releasing Tenant
from any of its obligations under this Lease, and the exercise of these rights
shall not be deemed an obligation of Landlord to perform such right in the
future.

                                      -31-

         SECTION XLV. GOVERNING LAW. This Lease shall be governed by the
provisions hereof and by the laws of the state in which the Premises are
located.

         SECTION XLVI. INTENTIONALLY DELETED.

         SECTION XLVII. FORCE MAJEURE. In the event that either party shall be
delayed or hindered in or prevented from the performance of act required under
this Lease, by reason of strikes, lockouts, labor troubles, inability to procure
materials, failure of power, restrictive governmental laws or regulations,
riots, insurrection, war or other reasons of a like nature not the fault of the
party delayed in performing work or doing the acts required, then performance of
such act shall be excused for the period of the delay and the period for such
party's performance of any such act shall be extended for a period equivalent to
the period of such delay. The provisions of this Section shall in no event
operate to excuse Tenant from the prompt payment of Rent, or Additional Rent, or
excuse performance due to lack of funds. In any case where work is to be paid
for out of insurance proceeds of condemnation awards, due allowance shall be
made, both to the party required to perform such work and to the party required
to make such payments, for delays in the collection of such proceeds or awards.

         SECTION XLVIII. MULTIPLE COUNTERPARTS. This Lease may be executed
simultaneously in two or more counterparts, each of which shall be deemed an
original but all of which shall constitute one and the same instrument.

         IN WITNESS WHEREOF, the parties hereto have set their hands and seals
as of the day and year first above written.

         The following Rules and Regulations constitute a part of the Lease and
of Tenant's obligations thereunder in respect of Tenant's use and occupancy of

permitted to perform any work outside their regular duties except upon special
instructions from the Building Manager.

         4.3. All schedules for the performance of your construction and repair

concern doing the work, and the name of the individual who will supervise the
performance of the work. You will be required to obtain from the persons doing

         5.1 You may not place a load upon any floor in the Premises or Building
exceeding the floor load which such floor was designed to carry and which is

positions of all business machines and mechanical equipment, including safes,
all of which shall be so placed as to distribute the weight. You shall place and
maintain your business machines and mechanical equipment in settings sufficient,
in Landlord's judgment, to absorb and prevent vibration, noise and annoyance.
You may not move any safe, heavy machinery, heavy equipment, freight, bulky
matter or fixtures into or out of the Building without Landlord's prior consent,
which consent may include a requirement to provide insurance, naming Landlord as
an insured, in such amounts as Landlord may deem reasonable. Notwithstanding the
foregoing, proper placement of all such business machines, etc. in the Premises
shall be your responsibility as Tenant.

         5.2. If any such safe, machinery, equipment, freight, bulky matter or
fixtures requires special handling, you must employ only persons holding a
Master Rigger's License to do such work; and all work in connection therewith
must comply with applicable laws and regulations. Any such moving shall be at
your own sole risk and hazard and you, as Tenant, will defend, exonerate,
indemnify and save Landlord harmless against and from any liability, loss,
injury, claim or suit resulting directly or indirectly from such moving.

                VI. ELECTRICAL SYSTEM: ENERGY CONSERVATION: WATER

         6.1. In order to assure that the Building's electrical standards are
not exceeded and to avert possible adverse effect on the Building's electric
system, you may not, without Landlord's prior consent, connect any fixtures,
appliances or equipment to the Building's electric distribution system other
than standard office equipment, such as typewriters, pencil sharpeners, adding
machines, hand-held or desk top calculators, dictaphones, office computers and
copies.

         6.2. Landlord reserves the right to implement policies and procedures
it deems, in its reasonable judgment, to be necessary or expedient in order to
conserve and/or preserve energy and related services, or as may be necessary or
required in order to comply with applicable government laws, rules, regulations,
codes, orders and standards.

         6.3. If you shall use water for any purpose other than for ordinary
lavatory and drinking purposes, Landlord may assess a reasonable charge for the
additional water so used, or install a water meter and thereby measure your
water consumption for all water purposes. In the latter event, you shall pay the
cost of the meter and the cost of installation thereof and shall keep such meter
and installation equipment in good working order and repair. You agree to pay
for water consumed, as shown on such meter, together with the sewer charge based
on such meter charges, as and when bills are rendered, and in default in making
such payment Landlord may pay such charges and collect the same from you as an
additional charge.

         6.4. The windows of the Building are designed for superior insulation
and to reduce glare. Building standard blinds or drapes present and elegant
appearance and contribute to the effectiveness of the Building's heating and
cooling systems. You should keep the blinds or drapes closed when windows are
exposed to the sun's rays in summer and keep them open when the sun is bright
