not usable (including loss of use due to loss of access or essential services),
the rent payable hereunder (including Lessee's Share of Operating Expense
increase) for the period during which such damage, repair or restoration
continues shall be abated, provided (1) the damage was not the result of the
negligence of Lessee, and (2) such abatement shall only be to the extent the
operation and profitability of Lessee's business as operated on the Premises is
adversely affected.  Except for said abatement of rent, if any, Lessee shall
have no claim against Lessor for any damage suffered by reason of any such
damage, destruction, repair or restoration.

     10.1  Payment of Taxes.  Lessor shall pay the real property tax as defined
           ----------------
in paragraph 10.3, applicable to the Office Building Project subject to
reimbursement by Lessee of Lessee's Share of such taxes in accordance with the
provisions of paragraph 4.2, except as otherwise provided in paragraph 10.2.

     10.2  Additional Improvements.  Lessee shall not be responsible for paying
           -----------------------
any increase in real property tax specified in the tax assessor's records and
work sheets as being caused by additional improvements placed upon the Office
Building Project by other lessees or by Lessor for the exclusive enjoyment of
any other lessee.  Lessee shall, however, pay to Lessor at the time that
Operating Expenses are payable under paragraph 4.2(c) the entirety of any
increase in real property tax if assessed solely by reason of additional
improvements placed upon the Premises by Lessee or at Lessee's request.

     10.3  Definition of "Real Property Tax."  As used herein, the term "real
           --------------------------------
property tax" shall include any form of real estate tax or assessment, general,
ordinary or extraordinary, and any license fee, commercial rental tax,
improvement bond or bonds, levy or tax (other than inheritance, personal income
or estate taxes) imposed on the Office Building Project or any portion thereof
by any authority having the direct or indirect power to tax, including any city,
county, state or federal government, or any school, agricultural, sanitary,
fire, street, drainage or other improvement thereof, against any legal or
equitable interest of Lessor in the Office Building Project or in any portion
thereof, as against Lessor's right to rent or other income therefrom, and as
against Lessor's business of leasing the Office Building Project.  The term
"real property tax" shall also include any tax, fee, or assessment of charge
(i) in substitution of, partially or totally, any tax, fee, levy, assessment or
charge hereinabove included within the definition of "real property

                                      -14-
<PAGE>

tax," or (ii) the nature of which was hereinbefore included within the
definition of "real property tax," or (iii) which is imposed for a right not
charged prior to June 1, 1979, or, if previously charged, has been increased
since June 1, 1978, or (iv) which is imposed as a result of a change in
ownership, as defined by applicable local statutes for property tax purposes, of
the Office Building Project or which is added to a tax or charge hereinbefore
included within the definition of real property tax by reason of such change of
ownership, or (v) which is imposed by reason of this transaction, any
modifications or changes hereto, or any transfers hereof.

     10.4  Joint Assessment.  If the improvements or property, the taxes for
           ----------------
which are to be paid separately by Lessee under paragraph 10.2 or 10.5 are
separately assessed, Lessee's portion of that tax shall be equitably determined
by Lessor from the respective valuations assigned in the assessor's worksheets
or such other information (which may include the cost of construction) as may be
reasonably available.  Lessor's reasonable determination thereof, in good faith,
shall be conclusive.

     10.5  Personal Property Taxes.

Lessor's real property, Lessee shall pay to Lessor the taxes attributable to
Lessee within ten (10) days after receipt of a written statement setting forth
the taxes applicable to Lessee's property.

Utilities.
---------

     11.1  Services Provided by Lessor.  Lessor shall provide heating,
           ---------------------------
ventilation, air conditioning, and janitorial service as reasonably required,
reasonable amounts of electricity for normal lighting and office machines, water
for reasonable and normal drinking and lavatory use, and replacement light bulbs
and/or fluorescent tubes and ballasts for standard overhead fixtures.

     11.2  Services Exclusive to Lessee.  Lessee shall pay for all water, gas,
           ----------------------------
heat, light, power, telephone and other utilities and services specially or
exclusively supplied and/or metered exclusively to the Premises or to Lessee,
together with any taxes thereon.  If any such services are not separately

Share or a reasonable proportion to be determined by Lessor of all charges
jointly, metered with other premises in the Building.

     11.3  Hours of Service.  Said services and utilities shall be provided
           ----------------
during generally accepted business days and hours or such other days or hours as
may

                                      -15-
<PAGE>

hereafter be set forth. Utilities and services required at other times shall be
subject to advance request and reimbursement by Lessee to Lessor of the cost
thereof.

     11.4  Excess Usage by Lessee.  Lessee shall not make connection to the
           ----------------------
utilities except by or through existing outlets and shall not install or use
machinery or equipment on the Premises that uses excess water, lighting or
power, or suffer or permit any act that causes extra burden upon utilities or
services, including but not limited to security services, over standard office
usage for the Office Building Project.  Lessor shall require Lessee to reimburse
Lessor for any excess expenses or costs that may arise out of a breach of this
subparagraph by Lessee.  Lessor may, in its sole discretion, install equipment
and/or separate metering applicable to Lessee's excess usage or loading.

     11.5  Interruptions.  There shall be no abatement of rent and Lessor shall
           -------------
not be liable in any respect whatsoever for the inadequacy, stoppage,
interruption or delay in utility or service due to riot, strike, labor dispute,
breakdown, accident, repair or other cause beyond Lessor's reasonable control.

Assignment and Subletting.
-------------------------

     12.1  Lessee shall not voluntarily or by operation of law assign, transfer,
mortgage, sublet, or otherwise transfer or exchange all or any part of Lessee's
interest in the Lease or in the Premises, without Lessor's prior written
consent, which Lessor shall not unreasonably withhold.  Lessor shall respond to
Lessee's request for consent hereunder in a timely manner and any attempted
assignment, transfer, mortgage, or encumbrance shall be void, and shall
constitute a material default and breach of this Lease without the need for
notice within the meaning of this paragraph 12 shall include the transfer or
transfers aggregating:  (a) if Lessee is a corporation, more than twenty-five
percent (25%) of the voting stock of such corporation, or (b) if Lessee is a
partnership, more than twenty-five percent (25%) of the profit and loss
participation in such partnership.

     12.2  Notwithstanding the provisions of paragraph 12.1 hereof, Lessee may
assign or sublet the Premises, or any portion thereof, without Lessor's consent,
to any corporation which controls, is controlled by or is under common control
with Lessee, or to any corporation resulting in the merger or consolidation with
Lessee, or to any person or entity which acquires all the assets of Lessee as a
going concern of the business and is being conducted on the Premises all of
which are referred to as "Lessee Affiliate"; provided that before such
assignment shall be effective, said Affiliate of Lessee under this Lease and
(b) Lessor shall be given written notice of such assignment and assumption.

     12.3  Terms and Conditions Applicable to Assignment and Subletting.
           ------------------------------------------------------------

           (a) No assignment or subletting shall release Lessee of Lessee's
obligations hereunder or alter the primary ability of Lessee to pay the rent or
other

                                      -16-
<PAGE>

sums due Lessor hereunder including Lessee's Share of Operating Expense
Increase, and to perform all other obligations to be performed by Lessee
hereunder.

           (b) Lessee shall allow no other party other than Lessee pending
approval or disapproval of such assignment.

           (c) Neither a delay in the approval or disapproval of such assignment
or subletting, nor the acceptance of rent, shall constitute a waiver or
renouncement of Lessor's claim for the breach of any of the terms or conditions
of this paragraph 12 or this Lease.

           (d) If Lessee's obligations under this Lease have been guaranteed by
third parties, then an assignment or sublease, and Lessor's consent to such
shall not be effective unless said guarantors give their written consent to such
sublease and the terms thereof.

           (e) The assignment or subletting shall not constitute a consent to
any subsequent assignment or subletting by Lessee in regards to any subsequent
or successive assignment or subletting by the sublessee. However, Lessor may
consent to subsequent sublettings and assignments of a sublease or any
amendments or modifications thereto without notifying Lessee or anyone else
liable on the Lease or sublease and without obtaining prior consent and such
action shall not relieve such persons from liability under this Lease or said
sublease; however, such persons shall not be responsible to the extent any such
amendment or modification enlarges or increases the obligations of the Lessee or
sublessee under this Lease or any sublease.

           (f) In the event of any default under this Lease, Lessor may proceed
directly against Lessee, any guarantors or any one else responsible for
performance of this Lease, including the sublessee, without first exhausting
Lessor's remedies against any other person or entity responsible to Lessor, of
any security held by Lessor or Lessee.

           (g) Lessor's written consent to any assignment or subletting of the
Premises by Lessee shall not constitute an acknowledgement that no default
exists under this Lease of the obligations to be performed by Lessee nor shall
such consent be deemed a waiver of any then existing default, except as may be
otherwise stated by Lessor at the time.

           (h) The discovery of the fact that any financial statement relied
upon by Lessor in giving its consent to an assignment or subletting was
materially false shall, at Lessor's election, render Lessor's said consent null
and void.

     12.4  Additional Terms and Conditions Applicable to Subletting.  Regardless
           --------------------------------------------------------
of Lessor's consent, the following terms and conditions shall apply to any
subletting

                                      -17-
<PAGE>

by Lessee of all or any part of the Premises and shall be deemed included in all
subleases under this Lease whether or not expressly incorporated therein:

           (a) Lessee hereby assigns and transfers to Lessor all of Lessee's
interest in all rentals and income arising from any sublease heretofore or
otherwise made by Lessee, and Lessor may collect such rent and income and apply
same toward Lessee's obligations under this Lease; provided, however, that until
a default shall occur in the performance of Lessee's obligations under this
Lease, Lessee may receive, collect and enjoy the rents accruing under such
sublease. Lessor shall not, by reason of this or any other assignment of such
sublease to Lessor nor by reason of the collection of rents from a sublessee, be
deemed liable to the sublessee for any failure of Lessee to perform and comply
with any of Lessee's obligations to such lessee under such sublease. Lessee
hereby irrevocably authorizes and directs any such sublessee, upon receipt of a
written notice from Lessor that a default exists in the performance of Lessee's
obligations under this Lease, to pay to Lessor the rents due and to become due
under the lease. Lessee agrees that such sublessee shall have the right to reply
upon any such statement and request from Lessor, and that such sublessee shall
pay such rents to Lessor without any obligation or right to inquire as to
whether such default exists and notwithstanding any notice from or claim from
Lessor to the contrary. Lessee shall have no right or claim against said
sublessee or Lessor for any such rents so paid by said sublessee to Lessor.

           (b) No sublease entered into by Lessee shall be effective unless and
until it has been approved in writing by Lessor. In entering into any sublease,
Lessee shall use only such form of sublessee as is satisfactory to Lessor, and
once approved by Lessor, such sublease shall not be changed or modified without
Lessor's prior written consent. Any sublease shall, by reason of entering into a
sublease under this Lease, be deemed, for the benefit of Lessor, have assumed
and agreed to conform and comply with each and every obligation herein to be
performed by Lessee other than such obligations as contrary to or inconsistent
with provisions contained in a sublease of which Lessor has expressly consented
in writing.

           (c) In the event Lessee shall default in the performance of its
obligations under this Lease, Lessor at its option and without any obligation to
do so may require any sublessee to attorn to Lessor, in which event Lessor shall
undertake the obligations of Lessee under such sublease from the time of the
exercise of said option to the termination of such sublease; provided, however,
Lessor shall not be liable for any prepaid rents or security deposit paid by
such sublessee to Lessee or for any other prior defaults of Lessee under such
sublease.

           (d) No sublessee shall further assign or sublet all or any part of
the Premises without Lessor's prior written consent.

                                      -18-
<PAGE>

           (e) With respect to any subletting to which Lessor has consented,
Lessor agrees to deliver a copy of any notice of default by Lessee to the
sublessee. Such sublessee shall have the right to cure a default of Lessee
within three (3) days after service of said notice of default upon such
sublessee, and the sublessee shall have a right of reimbursement and offset from
and against Lessee for any such defaults cured by the sublessee.

     12.5  Lessor's Expenses.  In the event Lessee shall assign or sublet the
           -----------------
Premises or request the consent of Lessor to any assignment or subletting Lessee
shall request the consent of Lessor for any-act Lessee proposes to do then
Lessee shall pay Lessor's reasonable costs and expenses in connection therewith,
including attorneys;  architects; engineers' or other consultants' fees.

     12.6  Conditions by Consent.  Lessor reserves the right to condition any
           ---------------------
approval to assign or sublet upon Lessor's determination that (a) the proposed
assignee or sublessee shall conduct a business on the Premises of a quality
substantially equal to that of Lessee and consistent with the general character
of the other occupants to the Office Building Project and not in violation of
any exclusives or rights then held by other tenants, and (b) the proposed
assignee or sublessee be at least as financially responsible as Lessee was
expected to be at the time of the execution of this Lease or of such assignment,
whichever is greater.

Default; Remedies.
------------------

     13.1  Default.  The occurrence of any one or more of the following events
           -------
shall constitute a material default of this Lease by Lessee:

           (a) The vacation or abandonment of the Premises by Lessee. Vacation
of the Premises shall include the failure to occupy the Premises for a
continuous period of sixty (60) days or more, whether or not the rent is paid.

           (b) The breach by Lessee of any of the covenants, conditions or
provisions of paragraphs 7.3(a), (b) or (d) (alterations), 12.1 (assignment or
subletting), 13.1(a) (vacation or abandonment), 13.1(e) (insolvency), 13.1(f)
(false statement), 16(a) (estoppel certificate), 30(b) (subordination) or 41.1
(easements), all of which are hereby deemed to be material, non-curable defaults
without the necessity of any notice by Lessor to Lessee thereof.

           (c) The failure by Lessee to make any payment of rent or any other
payment required to be made by Lessee hereunder, as and when due, and if such
failure shall continue for a period of three (3) days after written notice
thereof from Lessor to Lessee. In the event that Lessor serves Lessee with a
Notice to Pay Rent or Quit pursuant to applicable Unlawful Detainer statutes
such Notice to Pay Rent or Quit shall also constitute the Notice required by
this subparagraph.

                                      -19-
<PAGE>

           (d) The failure by Lessee to observe or perform any of the covenants,
conditions or provisions of this Lease to be observed or performed by Lessee
other than those referenced in subparagraphs (b) and (c), above, where such
failure shall continue for a period of thirty (30) days after written notice
thereof from Lessor to Lessee; provided, however, that if the nature of Lessee's
noncompliance is such that more than thirty (30) days are reasonably required
for its cure, then Lessee shall not be deemed to be in default if Lessee
commenced such cure within said thirty (30) day period and notice required to be
given to Lessee under applicable Unlawful Detainer statutes.

           (e) (i) The making by Lessee of any general arrangement or general
assignment for the benefit of creditors; (ii) Lessee becoming a "debtor" as
defined in 11 U.S.C. (S)101 or any successor statute thereto (unless, in the
case of a petition filed against Lessee, the same is dismissed within sixty (60)
days; (iii) the appointment of a trustee or receiver to take possession of
substantially all of Lessee's assets located at the Premises or of Lessee's
interest in this Lease, where possession is not restored to Lessee within thirty
(30) days; or (iv) the attachment, execution or other judicial seizure of
substantially all of Lessee's assets located at the Premises or of Lessee's
interest in this Lease, where such seizure is not discharged within thirty (30)
days.  In the event that any provision of this paragraph 13.1(3) is contrary to
any applicable law, such provision shall be of no force or effect.

           (f) The discovery by Lessor that any financial statement given to
Lessor by Lessee, or its successor in interest or by any guarantor of Lessee's
rights hereunder, was materially false.

     13.2  Remedies.  In the event of any material default or breach of this
           --------
Lease by Lessee, Lessor may at any time thereafter, with or without notice and
without limiting Lessor in the exercise of any right of remedy which Lessor may
have by reason of such default:

           (a) Terminate Lessee's right to possession of the Premises by any
lawful means, in which case this Lease and the term hereof shall terminate and
Lessee shall immediately surrender, possession of the Premises to Lessor, in
such event Lessor shall be entitled to recover from Lessee all damages incurred
by Lessor by reason of Lessee's default, including, but not limited to, the cost
of recovering possession of the Premises; expenses of reletting, including
necessary renovation and alteration of the Premises, reasonable attorneys' fees,
and any real estate commission actually paid; the worth at the time of award by
the court having jurisdiction thereof of the amount by which the unpaid rent for
the balance of the term after the time of such award exceeds the amount of such
rental loss for the same period that Lessee proves could be reasonably avoided;
that portion of the leasing commission paid by Lessor pursuant to paragraph 15
applicable to the unexpired term of this Lease.

                                      -20-
<PAGE>

           (b) Maintain Lessee's right to possession in which case this Lease
shall continue in effect whether or not Lessee shall have vacated or abandoned
the Premises. In such event Lessor shall be entitled to enforce all of Lessor'
rights and remedies under this Lease, including the right to recover the rent as
it becomes due hereunder.

           (c) Pursue any other remedy now or hereafter available to Lessor
under the laws or judicial decisions of the state wherein the Premises are
located. Unpaid installments of rent and other unpaid monetary obligations of
Lessee under the terms of this Lease shall bear interest from the date due at
the maximum rate then allowable by law.

     13.3  Default by Lessor.  Lessor shall not be in default unless Lessor
           -----------------
fails to perform obligations required of Lessor within a reasonable time, but in
no event later than thirty (30) days after written notice by Lessee to Lessor
and to the holder of any first mortgage or deed of trust covering the Premises
whose name and address shall have theretofore been furnished to Lessee in
writing, specifying wherein Lessor has failed to perform such obligation;
provided, however, that if the nature of Lessor's obligation is such that more
than thirty (30) days are required for performance then Lessor shall not be in
default if Lessor commences performance within such 30-day period and thereafter
diligently pursues the same to completion.

     13.4  Late Charges.  Lessee hereby acknowledges that the late payment by
           ------------
Lessee to Lessor of Base Rent, Lessee's Share of Operating Expense and or other
sums due hereunder will cause Lessor to incur costs not contemplated by this
Lease, the exact amount of which will be extremely difficult to ascertain.  Such
costs include, but are not limited to, processing and accounting charges, and
late charges which may be imposed on Lessor by the terms of any mortgage or
trust deed covering the Office Building Project.  Accordingly, if any
installment of Base Rent, Operating Expenses and or any other sum due from
Lessee shall not be received by Lessor or Lessor's designee within ten (10) days
after such amount shall be due.  Lessee, without any requirement for notice to
Lessor, Lessee shall pay to Lessor a later charge equal to 8% of such overdue
amount.  The parties hereby agree that such later charge represents a fair and
reasonable estimate of the costs Lessor will incur by reason of late payment by
Lessee.  Acceptance of such later charge by Lessor shall in not event constitute
a waiver of Lessee's default with respect to such overdue amount, nor prevent
Lessor from exercising any of the other rights and remedies granted hereunder.

Condemnation.  If the Premises or any portion thereof or the Office Building
------------
Project are taken under the power of eminent domain, or sold under the threat of
the exercise of said power (all of which are herein called "condemnation").
This Lease shall terminate as to the part so taken as of the date the condemning
authority takes title or possession, whichever first occurs; provided that if so
much of the Premises or the Office Building Project is taken by such
condemnation as would

                                      -21-
<PAGE>

substantially and adversely affect the operation and profitability of Lessee's
business conducted from the Premises, Lessee shall have the option, to be
exercised only in writing within thirty (30) days after Lessor shall have given
Lessee written notice of such taking (or in the absence of such notice, within
thirty (30) days after the condemning authority shall have taken possession), to
terminate this Lease as of the date the condemning authority takes such
possession. If Lessee does not terminate this Lease in accordance with the
foregoing, this Lease shall remain in full force and effect as to the portion of
the Premises remaining, except that the rent and Lessee's Share of Operating
Expense shall be reduced in the proportion that the floor area of the Premises
taken bears to the total floor area of the Premises. Common Areas condemned
shall be excluded from the Common Areas usable by Lessee and no reduction of
rent shall occur with respect thereto or by reason thereof. Lessor shall have
the option in its sole discretion to terminate this Lease as of the taking of
possession by the condemning authority by giving written notice to Lessee of
such election within thirty (30) days after receipt of notice of a taking by
condemnation of any part of the Premises or the Office Building Project. Any
award for the taking of all or any part of the Premises or the Office Building
Project under the power of eminent domain, or any claim made under threat of the
exercise of such power shall be the property of Lessor, whether such award shall
be made as compensation for depreciation in value of the leasehold or for the
taking of the fee, or as severance damages; provided, however, that Lessee shall
be entitled to any separate claim for loss of or damage to Lessee's trade
fixtures, removable personal property and unamortized tenant improvements that
have been paid for by Lessee. For that purpose the cost of such improvements
shall be amortized over the original term of this Lease excluding any options.
In the event that this Lease is not terminated by reason of such condemnation,
Lessor shall to the extent of severance damages received by Lessor in connection
with such condemnation, repair any damage to the Premises caused by such
condemnation except to the extent that Lessee has been reimbursed by the
condemning authority. Lessee shall pay any amount in excess of such severance
damages required to complete such repair.

Broker's Fee.
------------

     (a) The brokers involved in this transaction are none "listing broker" and
none as "cooperating broker",  ____________ real estate broker(s).  A
"cooperating Broker" is defined as any broker other than the listing broker
entitled to a share of any commission _________ under this Lease.  Upon
execution of this Lease by both parties, Lessor shall pay to said brokers
jointly, or in such separate shares as they may mutually designate in writing, a
fee as set forth in a separate agreement between Lessor and said broker(s), or
in the event there is no separate agreement between Lessor and said broker(s),
the sum of $0 for brokerage services rendered by said broker(s) to Lessor in
this transaction.

     (b) Lessor further agrees that (i) if Lessee exercises any Option, as
defined in paragraph 39.1 of this Lease, which is granted to Lessee under this
Lease, or any

                                      -22-
<PAGE>

subsequently granted option which is substantially similar to an Option granted
to Lessee under this Lease, or (ii) if Lessee acquires its rights to the
Premises or other premises described in this Lease which are substantially
similar to what Lessee would have acquired had an Option herein granted to
Lessee been exercised, or (iii) if Lessee remains in possession of the Premises
after the expiration of the term of this Lease after Lessee failed to exercise
an Option, or (iv) if said broker(s) are the procuring cause of any other lease
or sale entered into between the parties pertaining to the Premises and/or any
adjacent property in which Lessor has an interest, or (v) if the Base Rent is
increased, whether by agreement to an escalation clause contained herein, then
as to any of said transactions or rent increases. Lessor shall pay said
broker(s) a fee in accordance with the schedule of said broker(s) in effect at
the time of execution of this Lease. Said fee shall be paid at the time such
increased rental is determined.

     (c) Lessor agrees to pay said free not only on behalf of Lessor but also on
behalf of any person, corporation, association, or other entity having an
ownership interest in said real property or any part thereof, when such fee is
due hereunder.  Any transferee of Lessor's interest in this Lease, or other such
transfer is by agreement or by operation of law, shall be deemed to have assumed
Lessor's obligation under this paragraph 15.  Each listing and cooperating
broker shall be a third party beneficiary of the provisions of this paragraph 15
to the extent of their interest in any commission due under this Lease and may
enforce that right directly against Lessor; provided, however, that all brokers
having a right to any part of such total commission shall be a necessary party
to any suit with respect thereto.

     (d) Lessee and Lessor each represent and warrant to the other that neither
has had any dealing with any person, firm, broker or finder (other than the
person(s), if any, whose names are set forth in paragraph 15(a), above) in
connection with the negotiation of this Lease and/or the consummation of the
transaction contemplated hereby, and no other broker or other person, firm or
entity is entitled to any commission or finder's fee in connection with said
transaction and Lessee and Lessor do each hereby indemnify and hold the other
harmless from and against any costs, expenses, attorneys' fees or liability for
compensation or charges which may be claimed by any such unnamed broker, finder
or other similar party by reason of dealings or actions of the indemnifying
party.

Estoppel Certificate.
--------------------

     (a) Each party (as "responding party") shall at any time upon not less than
ten (10) days' prior written notice from the other party ("requesting party")
execute, acknowledge and deliver to the requesting party a statement in writing
(i) certifying that this Lease is unmodified and in full force and effect (or,
if modified, stating the nature of such modification and certifying that this
Lease, as so modified, is in full force and effect) and the date which the rent
and other charges are paid in advance, if any, and (ii) acknowledging that there
are not, to the responding party's

                                      -23-
<PAGE>

knowledge, any default on the part of the requesting party, or specifying such
defaults if any are claimed. Any such statement may be conclusively relied upon
by any prospective purchaser or encumbrancer of the Office Building Project or
of the business of Lessee.

     (b) AT the requesting party's option, the failure to deliver such statement
within such time shall be a material default of this Lease by the party
requested to respond, without any further notice to such party, or it shall be
conclusive upon such party that (i) this Lease is in full force and effect, and
no modification except as may be represented by the requesting party, (ii) there
are no uncured defaults in the requesting party's performance, (iii) if Lessor
is the requesting party, not more than one months' rent has been paid in
advance.

     (c) If Lessor desires to finance, refinance, or sell the Office Building
Project, or any part thereof, Lessee hereby agrees to deliver to any lender
purchaser designated by Lessor such financial statements of Lessee as may be
reasonably required by such lender or purchaser.  Such statements will include
the past three (3) years' financial statements of Lessee.  All such financial
statements shall be received by Lessor and such lender of purchaser in
confidence and shall be used only for the purposes herein set forth.

Liability.  The term "Lessor" as used herein shall mean only the owner or
---------
owners, at the time in question, of the fee title or a lessee's interest in a
ground lease of the Office Building Project, and except as expressly provided in
paragraph 15. In the event of any transfer of such title interest, Lessor herein
named (and in case of any subsequent transfers then the grantor) shall be
relieved from and after the date of such transfer liability as respects Lessor's
obligations thereafter to be performed, provided that any funds in the hands of
Lessor or the then grantor at the time of such transfer, in which Lessee has an
interest, shall be delivered to the grantee. The obligations contained in this
Lease to be performed by Lessor or shall, subject as aforesaid, be binding on
Lessor's successors and assigns, only during their respective periods of
ownership.

The invalidity of any provision of this Lease as determined by a court of
competent jurisdiction shall in no way affect the validity of other provisions
hereof.

Interest on Past-due Obligations.  Except as expressly herein provided, any
--------------------------------
amount due to Lessor not paid when due shall bear interest at the minimum rate
then allowable by law or judgments from the date due.  Payment of such interest
shall not excuse or cure any default by Lessee under this Lease; provided,
however, that interest shall not be payable on late charges incurred by Lessee
nor on any amounts upon which late charges are paid by Lessee.

Time of Essence.  Time is of the essence with respect to the obligations to be
---------------
performed under this Lease.

                                      -24-
<PAGE>

Additional Rent.  All monetary obligations of Lessee to Lessor under the terms
---------------
of this Lease, including but not limited to Lessee's Share of Operating Expense
increase and any other expenses payable by Lessee hereunder shall be deemed to
be rent.

Incorporation of Prior Agreements; Amendments.  This Lease contains all
---------------------------------------------
agreements of the parties with respect to any matter mentioned herein.  Prior or
contemporaneous agreement or understanding pertaining to any such matter shall
be effective.  This Lease may be modified in writing signed by the parties in
interest at the time of the modification.  Except as otherwise stated in this
Lease, Lessee hereby acknowledges that neither real estate broker listed in
paragraph 15 hereof nor any cooperating broker on this transaction nor the
Lessor or any employee or agent of any other persons has made any oral or
written warranties or representations to Lessee relative to the condition or use
by Lessee of the Premises or Office Building Project and Lessee acknowledges
that Lessee assumes all responsibility regarding the Occupational Safety Health
Act, the legal and adaptability of the Premises and the compliance thereof with
all applicable laws and regulations in effect during the term of this Lease.

Notices.  Any notice required or permitted to be given hereunder shall be in
-------
writing and may be given by personal delivery or by certified or registered
mail, and shall be deemed sufficiently given if delivered or addressed to Lessee
or to Lessor at the address noted below or adjacent to the name of the
respective parties, as the case may be.  Mailed notices shall be deemed given
upon actual receipt at the address required, or forty-eight hours following
deposit in the mail, postage prepaid, whichever first occurs.  Either party may
by notice to the other specify a different address for all purposes except that
upon Lessee's taking possession of the Premises, the Premises shall constitute
Lessee's address for notice purposes and of all notices required or permitted to
be given to Lessor hereunder shall be concurrently transmitted to such party or
parties at such addresses and may from time to time hereafter designate by
notice to Lessee.

Waivers.  No waiver by Lessor of any provision hereof shall be deemed a waiver
-------
of any other provision hereof or of any subsequent breach by Lessee of the same
or any other provision.  Lessor's consent to, or approval of, any act shall not
be deemed to render unnecessary the obtaining of Lessor's consent to or approval
of any subsequent act by Lessee.  The acceptance of rent hereunder by Lessor
shall not be a waiver of any preceding breach by Lessee of any provision hereof,
other than the failure of Lessee to pay the particular rent so accepted,
regardless of Lessor's knowledge of the preceding breach at the time of
acceptance of such rent.

Recording.  Either Lessor or Lessee shall, upon request of the other, execute,
---------
acknowledge and deliver to the other a "short form" memorandum of Lessee for
recording purposes.

                                      -25-
<PAGE>

Holding Over.  If Lessee, with Lessor's consent, remains in possession of the
------------
Premises or any part thereof after the expiration of the term hereof.  The new
occupancy shall be a tenancy from month to month upon all the provisions of this
Lease pertaining to the obligations of Lessee, except that rent payable shall be
two hundred percent (200%) of the rent payable immediately preceding the
termination date of this Lease, and all Options, if granted under the terms of
this Lease shall be deemed terminated and be of no further effect during said
month to month tenancy.

Cumulative Remedies.  No remedy or election hereunder shall be deemed exclusive
-------------------
but shall, wherever possible, be cumulative with all other remedies at law or in
equity.

Binding Effect; Choice of Law.  Subject to any provisions hereof restricting
-----------------------------
assignment or subletting by Lessee and subject to the provisions of paragraph
17, this Lease shall bind the parties, their personal representatives,
successors and assigns.  This Lease shall be governed by the laws of State where
the Office Building Project is located and any litigation concerning this Lease
between the parties hereto shall be initiated in the City in which the Office
Building Project is located.

Subordination.
-------------

     (a) This Lease, and any Option or right or first refusal granted hereby, at
Lessor's option, shall be subordinate to any ground lease, mortgage, deed of
trust, or any other hypothecation or security now or hereafter placed upon the
Office Building Project and to any and all advances made on security thereof and
to all renewals, modifications, consolidations, replacements and extensions
thereof.  Notwithstanding such subordination, Lessee's right to quiet possession
of the Premises shall not be disturbed if Lessee is not in default and so long
as Lessee shall pay the rent and continue and perform all of the provisions of
this Lease unless this Lease is otherwise terminated pursuant to its terms.
If any mortgagee, trustee or the Lessor shall elect to have this Lease and any
Options granted hereby prior to the line of its mortgage, deed of trust or
ground lease, and shall give written notice thereof to Lessee, this Lease and
such Option shall be deemed prior to such mortgage, deed of trust or ground
lease, whether Lease or such Options are dated prior or subsequent to the date
of said Mortgage, deed of trust or ground lease or the date of recording
thereof.

     (b) Lessee agrees to execute any documents required to effectuate an
attornment, a subordination, or to make this Lease or any Option granted
hereunder prior to the lien of any mortgage, deed of trust or ground lease, as
the case may be.  Lessee's failure to execute such documents within ten (10)
days after written demand shall constitute a material default by Lessee
hereunder without further notice to Lessee or, at Lessor's option, Lessor shall
execute such documents on behalf of Lessee as Lessee's attorney-in-fact..
Lessee does hereby make,

                                      -26-
<PAGE>

constitute and irrevocably appoint Lessor as Lessee's attorney-in-fact and
Lessee' name, place and stead, to execute such documents in accordance with this
paragraph 30(b).

Attorneys' Fees.
---------------

     If either party or the broker(s) named herein bring an action to enforce
the terms hereof or declare rights hereunder, the prevailing party in such
action, trial or appeal thereon, shall be entitled to his reasonable attorneys'
fees to be paid by the losing party as fixed by the court in the action or a
separate suit, and whether or not such action is pursued to decision or
judgment.  The provisions of this paragraph shall inure to the benefit of the
broker named herein who seeks to enforce a right hereunder.

     The attorneys' fee award shall not be computed in accordance with any court
fee schedule, but shall be such as to fully reimburse all attorneys' fees
reasonably incurred in good faith.

     Lessor shall be entitled to reasonable attorneys' fees and all other costs
and expenses incurred in the preparation and service of notice of action and
consultations in connection therewith, whether or not a legal transaction is
subsequently commenced in connection with such default.

Lessor's Access.
---------------

     Lessor and Lessor's agents shall have the right to enter the Premises at
reasonable times for the purpose of inspecting the same, performing services
required of Lessor, showing the same to prospective purchasers, lenders, or
lessees, taking such safety measures, erecting such scaffolding or other
necessary structures, making such alterations, repairs, improvements or
additions to the Premises or to the Office Building Project Lessor may
reasonably deem necessary or desirable and the erecting, using and maintaining
of utilities, services, pipes and conduits through the Premises and/or other
premises as long as there is no material adverse effect to Lessee's use of the
Premises.  Lessor may at any time place on or about the Premises or the Building
any ordinary "For Sale" signs and Lessor may at any time during the last 120
days of the term hereof place on or about the Premises any ordinary "For Lease"
signs.

     All activities of Lessor pursuant to this paragraph shall be without
abatement of rent, nor shall Lessor have any liability for the same.

     32.3  Lessor shall have the right to retain keys to the Premises and to
unlock all doors in or upon the Premises other than to files, vaults and safes,
and in the case of emergency to enter the Premises by any reasonably appropriate
means, and any such entry shall not be deemed a forceable or unlawful entry or
detainer of

                                      -27-
<PAGE>

the Premises or an eviction. Lessee waives any charges for damages or injuries
or interference with Lessee's property or business in connection therewith.

     1.  Auctions.  Lessee shall not conduct, nor permit to be conducted, either
         --------
voluntarily or involuntarily, any auction upon the Premises or the Common Areas
without first having obtained Lessor's prior written consent.  Notwithstanding
anything to the contrary in this Lease, Lessor shall not be obligated to
exercise any standard of reasonableness in determining whether to grant such
consent.  The holding of any auction on the Premises or Common Areas in
violation of this paragraph shall constitute a material default of this Lease.

     4.  Signs.  Lessee shall not place any sign upon the Premises or the Office
         -----
Building Project without Lessor's prior written consent.  Under no circumstances
shall Lessee place a sign on any roof of the Office Building Project.

     5.  Merger.  The voluntary or other surrender of this Lease, or a mutual
         ------
cancellation thereof, or a termination by Lessor, shall not work as a merger and
shall, at the option of Lessor, terminate all or any existing subtenancies or
may, at the option of Lessor, operate as an assignment to Lessor of any or all
of such subtenancies.

     6.  Consents.  Except for paragraphs 33 (auctions) and 34 (signs) hereof,
         --------
wherever in this Lease the consent of one party is required to an act of the
other party such consent shall not be unreasonably withheld or delayed.

     7.  Guarantor.  In the event that there is a guarantor of this Lease, said
         ---------
guarantor shall have the same obligations as Lessee under this Lease.

     8.  Quiet Possession.  Upon Lessee paying the rent for the Premises and
         ----------------
observing and performing all of the covenants, conditions and provisions on
Lessee's part to be observed and performed hereunder, Lessee shall have quiet
possession of the Premises for the entire term hereof subject to all of the
provisions of this Lease.  The individuals executing this Lease on behalf of
Lessor represent and warrant to Lessee that they are fully authorized and
legally capable of executing this Lease on behalf of Lessor and that such
execution is binding upon all parties holding an ownership interest in the
Office Building Project.

39.  Options.
     -------

     39.1  Definition.  As used in this paragraph the word "Option" has the

           ----------------
personal to the original Lessee and may be exercised only by the original Lessee
while occupying the Premises who does so without the intent of thereafter
assigning this Lease or subletting the Premises or any portion thereof, and may
not be exercised or be assigned, voluntarily or involuntarily, by or to any
person or entity other than Lessee; provided, however, that the Option may be
exercised by or assigned to any Lessee Affiliate as defined in paragraph 12.2 of
this Lease.  The Options, if any, herein granted to Lessee are not assignable
separate and apart from this Lease, nor may any Option be separated from this
Lease in any manner, either by reservation or otherwise.

     39.3  Multiple Options.  In the event that Lessee has any multiple options
           ----------------
to extend or renew this Lease a later option cannot be exercised unless a prior

           ----------------------------

     (a) Lessee shall have no right to exercise an Option, notwithstanding any
provision in the grant of Option to the contrary (i) during the time commencing
from the date Lessor gives to Lessee a notice of default pursuant to paragraph
13.1(c) or 13.1(d) and continuing until the noncompliance outlined in said
notice of default is cured, or (ii) during the period of time commencing on the
day after a monetary obligation to Lessor is due from Lessee and unpaid (without
any necessity for notice thereof to Lessee) and continuing until the obligation
is paid, or (iii) in the event that Lessor has given to Lessee three or more
notices of default under paragraph 13.1(c), or paragraph 13.1(d), whether or not
the defaults are cured, during the 12 month period of time immediately prior to
the time that Lessee attempts to exercise the subject Option, (iv) if Lessee has
committed any non-curable breach, including without limitation those described
in paragraph 13.1(b), or is otherwise in default of any of the terms, covenants
or conditions of this Lease.

     (b) The period of time within which an Option may be exercised shall not be
extended or enlarged by reason of Lessee's inability to exercise any Option
because of the provisions of paragraph 39.4(a).

     (c) All rights of Lessee under the provisions of an Option shall terminate
and be of no further force or effect, notwithstanding Lessee's due and timely
exercise of the Option, if, after such exercise and during the term of this
Lease,

                                      -29-

Security Measures - Lessor's Reservations.
-----------------------------------------

     40.1  Lessee hereby acknowledges that Lessor shall have no obligation
whatsoever to provide guard service or other security measures for the benefit
of the Premises or the Office Building Project.  Lessee assumes all
responsibility for the protection of Lessee, its agents, and invitees and the
property of Lessee and of Lessee's agents and invitees from acts of third
parties.  Nothing herein contained shall prevent Lessor, at Lessor's sole
discretion, from providing security protection for the Office Building Project
or any part thereof, in which event the cost thereof shall be included within a
definition of Operating Expenses, as set forth in paragraph 4.2(b).

     40.2  Lessor shall have the following rights:

     (a) To change the name, address or title of the Office Building Project or
building in which the Premises are located upon not less than 90 days prior
written notice;

     (b) To, at Lessee's expense, provide and install Building standard graphics

shall reasonably deem appropriate;

     (c) To permit any lessee the exclusive right to conduct any business as
long as such exclusive does not conflict with any rights expressly described
herein;

     (d) To place such signs, notices or displays as Lessor reasonably deems
necessary or advisable upon the roof, exterior of the buildings or Office
Building Project or on pole signs in the Common Areas;

     40.3  Lessee shall not:

Office Building Project or their name(s) in connection with Lessee's business;

                                      -30-

     (b) Suffer or permit anyone, except in emergency, to go upon the roof of
the Building.

Easements.
---------

     41.1  Lessor reserves to itself the right, from time to time, to grant such
easements, rights and dedications that Lessor deems necessary or desirable, and
to cause the recordation of Parcel Maps and restrictions, so long as such
easements, rights, dedications, maps and restrictions do not reasonably
interfere with the use of the Premises by Lessee.  Lessee shall sign any of the
aforementioned documents upon request of Lessor and failure to do so shall
constitute a material default of this Lease by Lessee without the need for
further notice to Lessee.

     41.2  The obstruction of Lessee's view, air, or light by any structure
erected in the vicinity of the Building, whether by Lessor or third parties,
shall in no way affect this Lease or impose any liability upon Lessor.

     Performance Under Protest.  If at any time a dispute shall arise as to any
     -------------------------
amount or sum of money to be paid by one party to the other under the provisions
hereof, the party against whom the obligation to pay the money is asserted shall
have the right to make payment "under protest" and such payment shall not be

relief (to the extent permitted by law) without the necessity of proving actual
damages.

         4.4. Retroactive Confirmation. For the same consideration received upon
              ------------------------
entering into this agreement, Executive hereby confirms that from the time he
first entered the Company's employment, all Developments which he may claim as
attributable to him during that period of employment have been disclosed and
assigned to the Company or may be considered "works for hire" created for the
exclusive benefit of the Company, all as if the provisions of section 4.2,
including without limiting the generality of the foregoing provisions of section
4.2(d), were in full force and effect and binding upon the Executive during that
period of employment.

         5. Employment Termination. The employment of the Executive by the
            ----------------------
Company pursuant to this Agreement shall terminate upon the occurrence of any of
the following:

         5.1 Expiration of the Employment Period unless it is theretofore
extended by mutual written agreement of the parties hereto;

         5.2 At the election of the Company, for cause, immediately upon written
notice by the Company to the Executive. For the purposes of this Section 5.2,
cause for termination shall be upon (a) a good faith finding by the Board of
Directors of the Executive's dishonesty, gross negligence or misconduct, or (b)
the conviction of the Executive of, or the entry of a pleading of guilty or nolo
contendere by the Executive to, any crime involving moral turpitude or any
felony;

         5.3 Immediately upon the death or disability of the Executive. As used
in this Agreement, the term "disability" shall mean the inability of the
Executive, due to a physical or mental disability, for a period of 180 days,
whether or not consecutive, during any 365-day period to perform the services
contemplated under this Agreement. A determination of disability shall be made
by a physician satisfactory to both the Executive and the Company, provided that
                                                                   -------------
if the Executive and the Board of Directors do not agree on a physician, the
Executive and the Company shall each select a physician and these two together
shall select a third physician, whose determination as to disability shall be
binding on all parties;

                                      -4-
<PAGE>

         5.4 At the election of the Executive, upon not less than one hundred
and eighty (180) days' prior written notice to the Company; or

         5.5 At the election of the Company, upon its payment to the Executive
of $200,000.00 for the earlier of (a) a period of 12 months following the
termination date and (b) the balance of the Employment Period.

         6. Effect of Termination. In the event the Executive's employment is
            ---------------------
terminated for any reason, the Company shall pay to the Executive the
compensation and benefits otherwise payable to him under Section 3 through the
last day of the Executive's actual employment by the Company except as may be
provided otherwise under section 5.5. The provisions of Sections 4 shall survive
the termination of this Agreement.

         7. Non-Competition.
            ---------------

         7.1 Executive hereby acknowledges that the Company has developed and
will develop substantial and valuable goodwill with its past, present and future
customers as a result of substantial investments of time, effort and capital.
Executive further acknowledges that he has acquired, and will continue to
acquire, a high level of skill and expertise in the Company's field of business
as a direct result of the Executive's employment by the Company, and that the
Company will likely suffer serious competitive damage if Executive were to
utilize that skill and expertise for the benefit of a competitor of the Company.
Accordingly, Executive hereby covenants and agrees that, during the Employment
Period or any extension thereof and for a period of one (1) year after
termination of his employment by the Company for any reason or no reason, or
from the date of any final judgment upholding the provisions of this Section 7,
whichever is later, Executive shall not, anywhere in North America, Europe and
the Pacific Rim countries, or any other state in which the Company conducts its
business, engage directly, work for or become employed by or associated with any
person or entity, in the same or similar lines of business as the Company.

         7.2 Executive acknowledges that the Company has a place of business,
has employees or representatives, or has advertised or sold products or services
in the restricted geographic region referenced in Section 7.1, thereby
warranting such geographic restriction. The Company and Executive agree that the
duration and geographic scope of the non-competition provisions set forth in
this Section 7 are reasonable. In the event that any court determines that the
duration or the geographic scope, or both, are unreasonable and that either such
provision is to that extent unenforceable, the parties hereto agree that the
provision shall remain in full force and effect for the greatest time period and
in the greatest area that would not render it unenforceable. Executive expressly
grants to the Company for a period of up to one (1) year, as the case may be,
following the termination of this Agreement the right to notify any person at
any time of the terms of this restrictive covenant.

         7.3 The provisions of this Section 7 shall survive any termination of
this Agreement.

         8. Notices. Any notice required or permitted by this Agreement shall be
            -------
given by registered or certified mail, return receipt required, addressed to the
Company at its then principal office, or to the Executive at his address
specified below, or to either party hereto at

                                      -5-
<PAGE>

such other address or addresses as he or it may from time to time specify for
the purpose in a notice similarly given.

         9. Entire Agreement. This Agreement contains the entire agreement of
            ----------------
the parties relating to the subject matter hereof, and there are no agreements,
representations or warranties not herein set forth. No modification of this
Agreement shall be valid unless in writing and signed by the parties hereto. The
waiver or breach of any term or condition of this Agreement shall not be deemed
to constitute a waiver of any subsequent breach of the same or any other term or
condition.

         10. Amendment. This Agreement may be amended or modified only by a
             ---------
written instrument executed by both the Company and the Executive.

         11. Governing Law. This Agreement shall be construed, interpreted and
             -------------
enforced in accordance with the laws of the Commonwealth of Massachusetts.

         12. Successors and Assigns. This Agreement shall extend to and be
             ----------------------
binding upon the Executive, his legal representative or representatives and
testate or intestate distributees, and this Agreement shall extend to and be
binding upon the Company, its successors and assigns. The term "Company" as used
herein shall include such successors and assigns. The term "successors and
assigns" as used herein shall mean a corporation or other entity acquiring all
or substantially all the assets and business of this Company (including this
Agreement) whether by operation of law or otherwise.

         13. Remedies. The rights and remedies of the parties hereunder shall
             --------
not be mutually exclusive, i.e., the exercise of one or more of the provisions
hereof shall not preclude the exercise of any other provisions hereof. Each of
the parties confirms that damages at law will be an inadequate remedy for a
breach or threatened breach of this Agreement and agrees that, in the event of a
breach or threatened breach of any provision hereof, the respective rights and
obligations hereunder shall be enforceable by specific performance, injunction
or other equitable remedy, but nothing herein contained is intended to, nor
shall it, limit or affect any rights at law or by statute or otherwise of any
party aggrieved as against the other for a breach or threatened breach of any
provision hereof, it being the intention by this Section to make clear the
agreement of the parties that the respective rights and obligations of the
parties hereunder shall be enforceable in equity as well as at law or otherwise.
Anything in the contrary notwithstanding, neither party shall seek or be
entitled to punitive damages for any breach alleged of the other and each party
hereby waives his or its right to a jury trial on any matters in dispute under
the Agreement.

         14. Severability. In the event that any section of this Agreement, or
             ------------
any provision of any such section, shall for any reason be held to be wholly
invalid, illegal or unenforceable, such invalidity, illegality or
unenforceability shall not affect any other section hereof, or any other
provisions of any affected section, and this Agreement shall be construed as if,
and enforced as fully as if, such invalid, illegal or unenforceable section or
provisions had never been contained herein. In the event any section, or any
provision thereof, is found to be partially invalid, illegal or unenforceable
(on the ground, for example, that it is excessive in scope), then such section
or

                                      -6-
<PAGE>

provision shall be enforced to the extent not invalid, illegal or unenforceable,
and its partial invalidity, illegality or unenforceability shall not affect any
other section of this Agreement.

         IN WITNESS WHEREOF, the parties hereto have duly executed and delivered
this Agreement under seal as of the day, month and year first above.
