          D.   Records. Licensee shall, and shall cause its Sublicensees and
               -------
Affiliates of either, to keep full and accurate books and records in sufficient

reporting period(s) to which they relate. During the term hereof and for three
(3) calendar year thereafter, Licensee shall permit, and shall cause its
Sublicensees and Affiliates of either to permit, accountants designated by ARCH,
to whom Licensee has no reasonable objection, to examine its books and records
for the purpose of verifying the accuracy of the written statements submitted by

than once in any calendar year. After completion of any such examination, ARCH
shall promptly notify Licensee in writing of any proposed modification to
Licensee's statement of sums due and payable. If Licensee accepts such
modification, or if the parties agree on other modifications, one party shall
promptly pay or credit the other in accordance with such resolution. Such
examination shall be made at the expense of ARCH, except that if such
examination discloses a discrepancy of * * * or more in the amount of Royalties
and other payments due ARCH, then Licensee shall reimburse ARCH for the cost of
such examination and pay the amount due with interest from the date at which

by law, calculated on the basis of a 360-day year for the number of days
actually elapsed, beginning on the due date and ending on the day prior to the
day on which payment is made in full. Interest accruing under this Paragraph
shall be due to ARCH on demand or upon payment of past due amounts, whichever is
sooner. The accrual or receipt by ARCH of interest under this Paragraph shall
not constitute a waiver by ARCH of any right it may otherwise have to declare a
default under this Agreement or to terminate this Agreement.

          F.   Single Royalty Payment. Royalties shall be payable only once with
               ----------------------

notify Licensee in writing of any country(ies) where it either previously
declared its intention to file under Paragraph 6.A. and subsequently decided not
to file in such country(ies) or previously filed and decided to abandon the
patent application or issued patent. All such notices shall be given so as to
allow Licensee a reasonable time within which to file in countries where ARCH
either does not intend to file or is not going to continue the prosecution or
maintenance of the application or patent, whichever is relevant. In all cases
where Licensee elects to file, Licensee shall file, prosecute and maintain the
applications and patents in ARCH's name and at Licensee's expense. In the case
of Group IV Patents, such patents shall be included in the definition of Group
IV Patents, for all purposes of this Agreement.

          C.   Patent Costs. Licensee agrees to pay all necessary and reasonable
               ------------

Group IV Patents in Canada, France, Germany, Japan, Netherlands, United Kingdom
and the United States, including those incurred by ARCH prior to the date of
this Agreement but not including any fees and expenses already paid for by * *
*. In this regard, Licensee agrees to pay ARCH * * * U.S. dollars within thirty
(30) business days of the date hereof as full reimbursement for such prior fees
and expenses incurred through December 5, 1996. Payment for fees and expenses
incurred after the date of this Agreement shall be invoiced to Licensee on a
monthly basis and Licensee agrees to pay such invoices within thirty (30) days
of receipt. Documentation received from the third party vendors to support the
amounts invoiced shall be included with each invoice. Licensee may raise any
objections to such amounts invoiced within the thirty (30) day time period for
payment provided Licensee has not preapproved such amount.

make advance payments or pay or reimburse ARCH for all or any portion of the
patent fees and expenses (including maintenance fees) as required by Paragraph
6.C. for any application or patent, Licensee's rights with respect to all such
applications and patents for which Licensee fails to make advance payments or
does not reimburse ARCH shall terminate effective sixty (60) days after written
notice from ARCH requesting such payment, unless payment in full is made within
such time. Such notice can be sent by ARCH at any time after the expiration of

or Affiliates of either. Licensee agrees and agrees to cause each of its
Sublicenses and Affiliates of either to agree not to sue any Indemnified Person
in connection with the development, production, use, sale or other disposition
of Products or the use of Technical Information, and all activities associated
therewith. ARCH shall be entitled to participate at its option and expense

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

Affiliates of either, provided that such assumption of the risk shall not apply
to the intentional misconduct or gross negligence by Indemnified Persons.
Indemnified Persons shall not, except for their intentional misconduct or gross
negligence, be responsible or liable for any injury, loss, or damage of any
kind, including but not limited to direct, indirect, special, incidental or
consequential damages or lost profits to Licensee, any Sublicensee, Affiliates
of either or customers or any of the foregoing, or for any such injury, loss or
damage to any other individual or entity, regardless of legal theory based on
the development, manufacture, use, sale or other disposition of Products or the
Technical Information, and all activities associated therewith. The above
limitations on liability apply even though the Indemnified Person may have been
advised of the possibility of such injury, loss or damage. Licensee shall not,
and shall require all Sublicensees and Affiliates of either to not, make any
agreements, statements, representations or warranties or accept any liabilities
or responsibilities whatsoever with regard to any person or entity which are

inventions claimed in the Licensed Patents. At ARCH's request, Licensee will

coverage under any such policies.

     9.   Confidentiality.
          ---------------

          A.   Confidentiality, Publications and Data Access. All information
               ---------------------------------------------
submitted by one party to the other concerning the Products, the Licensed
Patents, the invention(s) claimed in the Licensed Patents, and the Technical
Information shall be considered as confidential ("Confidential Information") and
shall be utilized only pursuant to the licenses granted hereunder. During the
term of this Agreement and for a period of ten.(10) years thereafter, neither
party shall disclose to any third party any Confidential Information received
from the other party without the specific written consent of such party.
Provided that Licensee may disclose Confidential Information belonging to ARCH
to potential sublicensees for the purpose of evaluating their interest in
entering into a Sublicense but only after entering into a confidentiality
agreement on the same terms as those contained in this Paragraph. The foregoing
shall not apply where Confidential Information a) was or becomes public through
no fault of the receiving party, b) was, at the time of receipt, already in the
possession of the receiving party as evidenced by its written records, c) was
obtained from a third party legally entitled to use and disclose the same, or d)
is required by law to be disclosed to a governmental agency.

          B.   Publications. ARCH shall provide to Licensee copies of any
               ------------
proposed written publication by ARCH containing any Confidential Information
and, to the extent ARCH is aware of them, proposed publications containing any
Confidential information by the Inventor(s). Licensee agree to provide copies of
any proposed written publication of Licensee, its Sublicensees and Affiliates of
either of them to ARCH. The parties shall provide copies of such proposed
written publications at least ninety (90) days in advance of publication in
order to protect potentially patentable subject matter. The receiving party may
request, and the disclosing party agrees, that publication will be withheld for
an additional thirty (30) days, if required, to obtain patent protection. The
receiving party may object to such proposed publication or disclosure on the
grounds that the publication contains Confidential Information of the objecting
party. At the request of the objecting party, Confidential Information of such
party shall be deleted from the publication.

     10.  Infringement. In the event of an infringement of a Licensed Patent the
          ------------
following shall apply:

          A.   Notice. Each party shall give the other written notice if one of
               ------
them becomes aware of any infringement by a third party of any Licensed Patent.
Upon notice of any such infringement, the parties shall promptly consult with
one another with a view toward reaching agreement on a course of action to be
pursued.

          B.   Licensee's Right to Bring Infringement Action.
               ---------------------------------------------

               (1)  If a third party infringes any patent included in the
Licensed Patents within the Field, Licensee shall have the right to institute
and prosecute an action or proceeding to abate such infringement and to resolve
such matter by settlement or otherwise. Licensee agrees to notify ARCH of its
intention to bring an action or proceeding prior to filing the same and in
sufficient time to allow ARCH the opportunity to discuss with Licensee the
choice of counsel for such matter. Licensee agrees to hire counsel reasonably
acceptable to ARCH. Licensee shall keep ARCH timely informed of material
developments in the prosecution or settlement of such action or proceeding.
Licensee shall be responsible for all costs and expenses of any action or
proceeding against infringers which Licensee initiates. ARCH shall cooperate
fully by joining as a party plaintiff if required to do so by law to maintain
such action or proceeding and by executing and making available such documents
as Licensee may reasonably request. Licensee agrees to promptly reimburse ARCH
for its reasonable third party out-of-pocket fees and expenses incurred in
joining an action or proceeding or cooperating with Licensee. ARCH may be
represented by counsel in any such legal proceedings, at ARCH's own expense,
subject to reimbursement under Paragraph 10.B.(3), acting in an advisory but not
controlling capacity.

               (2)  The prosecution, settlement, or abandonment of any action or
proceeding under Paragraph 10.B.(1) shall be at Licensee's reasonable discretion
provided that Licensee shall not have any right to surrender any of ARCH's
rights to the Licensed Patents or to grant any infringer any rights to the
Licensed Patents.

               (3)  Except as provided herein, all amounts of every kind and
nature recovered from an action or proceeding, of infringement by Licensee shall
belong to Licensee. If the amounts recovered by Licensee exceed Licensee's
reasonable third party out-of-pocket fees and expenses, Licensee shall reimburse
ARCH for ARCH's reasonable out-of-pocket fees and expenses incurred in hiring
its own counsel. After deduction of the fees and expenses of both parties to
this Agreement, any remaining amounts recovered shall be considered Net Revenue
under this Agreement and subject to Royalty payments in accordance with
Paragraph 3.

          C.   ARCH's Right to Bring Infringement Action. If a third party
               -----------------------------------------
infringes any patent included in the Licensed Patents within the Field which
ARCH wishes to prosecute, ARCH shall first notify Licensee in writing and
request that Licensee bring an action or proceeding against the infringing third
party. If Licensee declines or fails to bring such an action or proceeding
within ninety (90) of receipt of the notice, ARCH shall have the right, at its
discretion, to institute and prosecute an action or proceeding to abate such
infringement and to resolve such matter by settlement or otherwise. Licensee
shall cooperate fully by joining as a party plaintiff if required to do so by
law to maintain such action and by executing and making available such documents
as ARCH may reasonably request. If the amounts recovered by ARCH exceed its
reasonable out-of-pocket fees and expenses, ARCH agrees to pay Licensee for its
and its Sublicensees' reasonable out-of-pocket third party expenses incurred by
it in cooperating in the action or proceeding. Except as specifically provided
in this Paragraph, ARCH shall have the right to retain all amounts recovered of
every kind and nature. Amounts recovered by ARCH shall not be considered Net
Revenue under this Agreement and shall not give rise to Royalty payments under
Paragraph 3.

such failure within the sixty (60) days.

               (3) If Licensee shall have filed by or against it a petition
under any bankruptcy or insolvency law and such petition is not dismissed within

substantially all of its assets for the benefit of its creditors ARCH may
terminate this Agreement by written notice effective as of the (i) date of
filing by Licensee of any such petition, (ii) date of any such assignment to
creditors, or (iii) end of the sixty (60) days if a petition is filed against it
and not dismissed by such time, whichever is applicable.

               (4) If Licensee shall be dissolved, liquidated or otherwise

bound by a decision of the arbitration panel with respect to the matter in
dispute. All proceedings of the arbitration panel shall be held in Wilmington,
Delaware. The panel's costs and fees shall be borne by the party bringing the
action. The arbitrators shall presume that all claims of all Licensed Patents
are valid and enforceable, and shall not have the power to assess the validity
or enforceability of the Licensed Patents.

            B.   Appeals. There shall be no appeal from an arbitration panel's
                 -------
unanimous decision. In the event of a majority decision by the arbitration
panel, a dissatisfied party may appeal the panel's decision to the American

appeal within thirty (30) days after receipt of the arbitration panel's decision

appeal. The AAA is hereby authorized to make arrangements for such arbitration,
to be held under the procedures provided by its arbitration rules. Judgment upon

judgment of the initial panel, may be entered in any court in any country having
jurisdiction, after any and all applicable appeal periods have passed.

portion thereof;

          (f) To do and perform such other acts and make such other changes in,

may, in the exercise of sound business judgment deem to be appropriate.

3.   Term.

     3.1  Term. The term and Commencement Date of this Lease shall be as
specified in paragraph 1.5 of the Basic Lease Provisions.

     3.2  Delay in Possession. Notwithstanding said Commencement Date, if for
any reason Lessor cannot deliver possession of the Premises to Lessee on said
date and subject to paragraph 3.2.2, Lessor shall not be subject to any
liability therefor, nor shall such failure affect the validity of this Lease or
the obligations of Lessee hereunder or extend the term hereof; but in such case,
Lessee shall not be obligated to pay rent or perform any other obligation of
Lessee under the terms of this Lease, except as may be otherwise provided in
this Lease, until possession of the Premises is tendered to Lessee, as
hereinafter defined; provided, however, that if Lessor shall not have delivered
possession of the Premises within sixty (60) days following said Commencement
Date, as the same may be extended under the terms of a Work Letter executed by
Lessor and Lessee, Lessee may, at Lessee's option, by notice in writing to
Lessor within ten (10) days thereafter, cancel this Lease, in which event the
parties shall be discharged from all obligations hereunder; provided, however,
that, as to Lessee's obligations, Lessee first reimburses Lessor for all costs
incurred for Non-Standard Improvements and, as to Lessor's obligations, Lessor
shall return any money previously deposited by Lessee (less any offsets due
Lessor for Non-Standard Improvements); and provided further, that if such
written notice by Lessee is not received by Lessor within said ten (10) day
period, Lessee right to cancel this Lease hereunder shall terminate and be of no
further force or effect.

          3.2.1  Possession Tendered-Defined. Possession of the Premises shall
be deemed tendered to Lessee ("Tender of Possession") when (1) the improvements
to be provided by Lessor under this Lease are substantially completed, (2) the
Building utilities are ready for use in the Premises, (3) Lessee has reasonable
access to the Premises, and (4) ten (10) days shall have expired following
advance written notice to Lessee of the occurrence of the matters described in
(1), (2) and (3), above of this paragraph 3.2.1.

          3.2.2  Delays Caused by Lessee. There shall be no abatement of rent,
and the sixty (60) day period following the Commencement Date before which
Lessee's right to cancel this Lease accrues under paragraph 3.2, shall be deemed
extended to the extent of any delays caused by acts or omissions of Lessee, its
agents, employees and contractors.

     3.3  Early Possession. If Lessee occupies the Premises prior to said
Commencement Date, such occupancy shall be subject to all provisions of this
Lease, such occupancy shall not change the termination date, and Lessee shall
pay rent for such occupancy.

     3.4  Uncertain Commencement. In the event commencement of the Lease term is
defined as the completion of the improvements, Lessee and Lessor shall execute
an amendment to this Lease establishing the date of Tender of Possession (as
defined in paragraph 3.2.1) or the actual taking of possession by Lessee,
whichever first occurs, as the Commencement Date.

4.   Rent

     4.1  Base Rent. Subject to adjustment as hereinafter provided in paragraph
4.3, and except as may be otherwise expressly provided in this Lease, Lessee
shall pay to Lessor the Base Rent for the Premises set forth in paragraph 1.6 of
the Basic Lease Provisions, without offset or deduction. Lessee shall pay Lessor
upon execution hereof the advance Base Rent described in paragraph 1.8 of the
Basic Lease Provisions. Rent for any period during the term hereof which is for
less than one month shall be prorated based upon the actual number of days of
the calendar month involved. Rent shall be payable in lawful money of the United
States to Lessor at the address stated herein or to such other persons or at
such other places as Lessor may designate in writing.

     4.2  Operating Expenses. Lessee shall pay to Lessor during the term hereof,

Operating Expenses, as hereinafter defined, during each calendar year of the
term of this Lease, in accordance with the following provisions:

          (a) "Lessee's Share" is defined, for purposes of this Lease, as the
percentage set forth in paragraph 1.10 of the Basic Lease Provisions, which
percentage has been determined by dividing the approximate square footage of
the Premises by the total approximate square footage of the rentable space
contained in the Office Building Project. It is understood and agreed that the
square footage figures set forth in the Basic Lease Provisions are
approximations which Lessor and Lessee agree are reasonable and shall not be
subject to revision except in connection with an actual change in the size of
the Premises or a change in the space available for lease in the Office Building
Project.

          (b) "Operating Expenses" is defined, for purposes of this Lease, to
include all reasonable costs, if any, incurred by Lessor in the exercise of its
reasonable discretion, for:

              (i)     The operation, repair, maintenance, and replacement, in
neat, clean, safe, good order and condition, of the Office Building Project,
including but not limited to, the following:

                 (aa) The Common Areas, including their surfaces, coverings,
decorative items, carpets, drapes and window coverings, and including parking
areas, loading and unloading areas, trash areas, roadways, sidewalks, walkways,
stairways, parkways, driveways, landscaped areas, striping, bumpers, irrigation

              (ii)    Trash disposal, janitorial and security services;

              (iii)   Any other service to be provided by Lessor that is
elsewhere in this Lease stated to be an "Operating Expense";

              (iv)    The cost to the premiums for the liability and property
insurance policies to be maintained by Lessor under paragraph 8 hereof;

              (v)     The amount of the real property taxes to be paid by Lessor
under paragraph 10.1 hereof;

              (vi)    The cost of water, sewer, gas, electricity, and other
publicity mandated services to the Office Building Project;

              (vii)   Labor, salaries and applicable fringe benefits and costs,
materials, supplies and tools, used in maintaining and/or cleaning the Office
Building Project and accounting and a management fee attributable to the
operation of the Office Building Project;

              (viii)  Replacing and/or adding improvements mandated by any
governmental agency and any repairs or removals necessitated thereby amortized
over its useful life according to Federal income tax regulations or guidelines
for depreciation thereof;

              (ix)    Replacements of equipment or improvements that have a
useful life for depreciation purposes according to Federal Income tax guidelines
of five (5) years or less, as amortized over such life.

          (c) Operating Expenses shall not include the costs of replacements of
equipment or improvements that have a useful life for Federal Income tax
purposes in excess of five (5) years unless it is of the type described in
paragraph 4.2(b)(viii), in which case their cost shall be included as above
provided.

          (d) Operating Expenses shall not include any expenses paid by any
lessee directly to third parties, or as to which Lessor is otherwise reimbursed
by any third party, other tenant, or by insurance proceeds.

          (e) Lessee's Share of Operating Expenses shall be payable by Lessee
within twenty (20) days after a reasonably detailed statement of actual expenses
is presented to Lessee by Lessor. At Lessor's option, however, an amount may be
estimated by Lessor from time to time of Lessee's Share of annual Operating
Expenses and the same shall be payable monthly or quarterly, as Lessor shall
designate, during each calendar year of the Lease term, on the same day as the
Base Rent is due hereunder, in the event that Lessee pays Lessor's estimate of
Lessee's Share of Operating Expenses as aforesaid, Lessor shall deliver to
Lessee within sixty (60) days after the expiration of each calendar year a
reasaonably detailed statement showing Lessee's Share of the actual Operating
Expenses incurred during the preceding year. If Lessee's payments under this
paragraph 4.2(e) during said preceding calendar year exceed Lessee's Share as
indicated on said statement, Lessee shall be entitled to credit the amount of
such overpayment against Lessee's Share of Operating Expenses next falling due.
If Lessee's payments under this paragraph during said preceding calendar year
were less than Lessee's Share as indicated on said statement, Lessee shall pay
to Lessor the amount of the deficiency within twenty (20) days after delivery by
Lessor to Lessee of said statement.

     4.3  Rent Increase.

          4.3.1  At the times set forth in paragraph 1.7 of the Basic Lease
Provisions, the monthly Base Rent payable under paragraph 4.1 of this Lease
shall be adjusted by the increase, if any, in the Consumer Price Index of the
Bureau of Labor Statistics of the Department of Labor for All Urban Consumers,
(1967=100), "All items," for the city nearest the location of the Building,
herein referred to as "C.P.I.," since the date of this Lease.

          4.3.2  The monthly Base Rent payable pursuant to paragraph 4.3.1 shall
be calculated as follows: the Base Rent payable for the first month of the term
of this Lease, as set forth in paragraph 4.1 of this Lease, shall be multiplied
by a fraction the numerator of which shall be the C.P.I. of the calendar month
during which the adjustment is to take effect, and the denominator of which
shall be the C.P.I. for the calendar month in which the original Lease term
commences. The sum so calculated shall constitute the new monthly Base Rent
hereunder, but, in no event, shall such new monthly Base Rent be less than the
Base Rent payable for the month immediately preceding the date for the rent
adjustment.

          4.3.3  In the event the compilation and/or publication of the C.P.I.
shall be transferred to any other governmental department or bureau or agency
or shall be discontinued, then the index most nearly the same as the C.P.I.
shall be used to make such calculations. In the event that Lessor and Lessee
cannot agree on such alternative index, then the matter shall be submitted for
decision to the American Arbitration Association in the county in which the
Premises are located, in accordance with the then rules of said association and
the decision of the arbitrators shall be binding upon the parties,
notwithstanding one party failing to appear after due notice of the proceeding.
The cost of said Arbitrators shall be paid equally by Lessor and Lessee.

          4.3.4  Lessee shall continue to pay the rent at the rate previously in
effect until the increase, if any, is determined. Within five (5) days following
the date on which the increase is determined, Lessee shall make such payment to
Lessor as will bring the increased rental current, commencing with the effective
date of such increase through the date of any rental instalments then due.
Thereafter the rental shall be paid at the increased rate.

          4.3.5  At such time as the amount of any change in rental required by
this Lease is known or determined, Lessor and Lessee shall execute an amendment
to this Lease setting forth such change.

     5.   Security Deposit. Lessee shall deposit with Lessor upon execution
hereof the security deposit set forth in paragraph 1.9 of the Basic Lease
Provisions as security for Lessee's faithful performance of Lessee's
obligations hereunder. If Lessee fails to pay rent or other charges due
hereunder, or otherwise defaults with respect to any provision of this Lease,
Lessor may use, apply or retain all or any portion of said deposit for the
payment of or otherwise defaults with respect to any provision of this Lease,
Lessor may use, apply or retain all or any portion of said deposit for the
payment of any rent or other charge in default for the payment of any other sum
to which Lessor may become obligated by reason of Lessee's default, or to

                                                             Initials:    KRD
                                                                       ---------

compensate Lessor for any loss or damage which Lessor may suffer thereby. If
Lessor so uses or applies all or any portion of said deposit, Lessee shall
within ten (10) days after written demand therefor deposit cash with Lessor in
an amount sufficient to restore said deposit to the full amount then required of
Lessee. Lessor shall not be required to keep said security deposit separate from
its general accounts. If Lessee performs all of Lessee's obligations hereunder,
said deposit, or so much thereof as has not heretofore been applied by Lessor,
shall be returned, without payment of interest or other increment for its use,
to Lessee (or, at Lessor's option, to the last assignee, if any, of Lessee's
interest hereunder) at the expiration of the term hereof, and after Lessee has
vacated the Premises. No trust relationship is created herein between Lessor and
Lessee with respect to said Security Deposit.

6. Use.

   6.1  Use. The Premises shall be used and occupied only for the purpose
set forth in paragraph 1.4 of the Basic Lease Provisions or any other use which
is reasonably comparable to that use and for no other purpose.

   6.2  Compliance with Law.

        (a)  Lessor warrants to Lessee that the Premises, in the state existing
on the date that the Lease term commences, but without regard to alterations or
improvements made by Lessee or the use for which Lessee will occupy the
Premises, does not violate any covenants or restrictions of record, or any
applicable building code, regulation or ordinance in effect on such Lease term
Commencement Date. In the event it is determined that this warranty has been
violated, then it shall be the obligation of the Lessor, after written notice
from Lessee, to promptly, at Lessor's sole cost and expense, rectify any such
violation.

        (b)  Except as provided in paragraph 6.2(a) Lessee shall, at Lessee's
expense, promptly comply with all applicable statutes, ordinances, rules
regulations, orders, covenants and restrictions of record, and requirements of
any fire insurance underwriters or rating bureaus, now in effect or which may
hereafter come into effect, whether or not they reflect a change in policy from
that now existing, during the term or any part of the term hereof, relating in
any manner to the Premises and the occupation and use by Lessee of the Premises.
Lessee shall conduct its business in a lawful manner and shall not use or permit
the use of the Premises or the Common Areas in any manner that will tend to
create waste or a nuisance or shall tend to disturb other occupants of the
Office Building Project.

   6.3  Condition of Premises.

        (a)  Lessor shall deliver the Premises to Lessee in a clean condition on
the Lease Commencement Date (unless Lessee is already in possession) and Lessor
warrants to Lessee that the plumbing, lighting, air conditioning, and heating
system in the Premises shall be in good operating condition. In the event that
it is determined that this warranty has been violated, than it shall be the
obligation of Lessor, after receipt of written notice from Lessee setting forth
with specificity the nature of the violation, to promptly, at Lessor's sole
cost, rectify such violation.

        (b)  Except as otherwise provided in this Lease, Lessee hereby accepts
the Premises and the Office Building Project in their condition existing as of
the Lease Commencement Date or the date that Lessee takes possession of the
Premises, whichever is earlier, subject to all applicable zoning, municipal,
county and state laws, ordinances and regulations, governing and regulating the
use of the Premises, and any easements, covenants or restrictions of record, and
accepts this Lease subject thereto and to all matters disclosed thereby and by
any exhibits attached hereto. Lessee acknowledges that it has satisfied itself
by its own independent investigation that the Premises are suitable for its
intended use, and that neither Lessor nor Lessor's agent or agents has made any
representation or warranty as to the present or future suitability of the
Premises, Common Areas, or Office Building Project for the conduct of Lessee's
business.

7. Maintenance, Repairs, Alterations and Common Areas Services.

   7.1  Lessor's Obligations. Lessor shall keep the Office Building Project,
including the Premises, interior and exterior walls, roof, and common areas, and
the equipment whether used exclusively for the Premises or in common with other
premises, in good condition and repair; provided, however, Lessor shall not be
obligated to paint, repair or replace wall coverings, or to repair or replace
any improvements that are not ordinarily a part of the Building or are above
then Building standards. Except as provided in paragraph 9.5, there shall be no
abatement of rent or liability of Lessee on account of any injury or
interference with Lessee's business with respect to any improvements,
alterations or repairs made by Lessor to the Office Building Project or any part
thereof. Lessee expressly waives the benefits of any statute now or hereafter in
effect which would otherwise afford Lessee the right to make repairs at Lessor's
expense or to terminate this Lease because of Lessor's failure to keep the
Premises in good order, condition and repair.

   7.2  Lessee's Obligations.

        (a)  Notwithstanding Lessor's obligation to keep the Premises in good
condition and repair, Lessee shall be responsible for payment of the cost
thereof to Lessor as additional rent for that portion of the cost of any
maintenance and repair of the Premises, or any equipment (wherever located) that
serves only Lessee or the Premises, to the extent such cost is attributable to
causes beyond normal wear and tear. Lessee shall be responsible for the cost of
painting, repairing or replacing wall coverings, and to repair or replace any
Premises improvements that are not ordinarily a part of the Building or that are
above then Building standards. Lessor may, at its option, upon reasonable
notice, elect to have Lessee perform any particular such maintenance or repairs
the cost of which is otherwise Lessee's responsibility hereunder.

        (b)  On the last day of the term hereof, or on any sooner termination,
Lessee shall surrender the Premises to Lessor in the same condition as received,
ordinary wear and tear excepted, clean and free of debris. Any damage or
deterioration of the Premises shall not be deemed ordinary wear and tear if the
same could have been prevented by good maintenance practices by Lessee. Lessee
shall repair any damage to the Premises occasioned by the installation or
removal of Lessee's trade fixtures, alterations, furnishings and equipment.
Except as otherwise stated in this Lease, Lessee shall leave the air lines,
power panels, electrical distribution systems, lighting fixtures, air
conditioning, window coverings, wall coverings, carpets, wall panelling,
ceilings and plumbing on the Premises and in good operating condition.

   7.3  Alterations and Additions.

        (a)  Lessee shall not, without Lessor's prior written consent make any
alterations, improvements, additions, Utility installations or repairs in, on or
about the Premises, or the Office Building Project. As used in this paragraph
7.3 the term "Utility Installation" shall mean carpeting, window and wall
coverings, power panels, electrical distribution systems, lighting fixtures, air
conditioning, plumbing, and telephone and telecommunication wiring and
equipment. At the expiration of the term, Lessor may require the removal of any
or all of said alterations, improvements, additions or Utility Installations,
and the restoration of the Premises and the Office Building Project to their
prior condition, at Lessee's expense. Should Lessor permit Lessee to make its
own alterations, improvements, additions or Utility Installations, lessee shall
use only such contractor as has been expressly approved by Lessor, and Lessor
may require Lessee to provide Lessor, at Lessee's sole cost and expense, a lien
and completion bond in an amount equal to one and one-half times the estimated
cost of such improvements, to insure Lessor against any liability for mechanic's
and materialmen's liens and to insure completion of the work. Should Lessee make
any alterations, improvements, additions or Utility Installations without the
prior approval of Lessor, or use a contractor not expressly approved by Lessor,
Lessor may, at any time during the term of this Lease, require that Lessee
remove any part or all of the same.

        (b)  Any alterations, improvements, additions or Utility Installations
in or about the Premises or the Office Building Project that Lessee shall desire
to make shall be presented to Lessor in written form, with proposed detailed
plans. If Lessor shall give its consent to Lessee's making such alteration,
improvement, addition or Utility Installation, the consent shall be deemed
conditioned upon Lessee acquiring a permit to do so from the alteration,
improvement, addition or Utility Installation, the consent shall be deemed
conditioned upon Lessee acquiring a permit to do so from the applicable
governmental agencies, furnishing a copy thereof to Lessor prior to the
commencement of the work, and compliance by Lessee with all conditions of said
permit in a prompt and expeditious manner.

        (c)  Lessee shall pay, when due, all claims for labor or materials
furnished to or for Lessee at or for use in the Premises, which claims are or
may be secured by any mechanic's or materialmen's lien against the Premises, the
Building or the Office Building Project, or any interest therein.

        (d)  Lessee shall give Lessor not less than ten (10) days' notice prior
to the commencement of any work in the Premises by Lessee, and Lessor shall have
the right to post notices of non-responsibility in or on the Premises or the
Building as provided by law. If Lessee shall, in good faith, contest the
validity of any such lien, claim or demand, then Lessee shall, at its sole
expense defend itself and Lessor against the same and shall pay and satisfy any
such adverse judgment that may be rendered thereon before the enforcement
thereof against the Lessor or the Premises, the Building or the Office Building
Project, upon the condition that if Lessor shall require, Lessee shall furnish
to Lessor a surety bond satisfactory to Lessor in an amount equal to such
contested lien claim or demand indemnifying Lessor against liability for the
same and holding the Premises, the Building and the Office Building Project free
from the effect of such lien or claim. In addition, Lessor may require Lessee to
pay Lessor's reasonable attorneys fees and costs in participating in such action
if Lessor shall decide it is to Lessor's best interest so to do.

        (e)  All alterations, improvements, additions and Utility installations

(whether or not such Utility Installations constitute trade fixtures of Lessee),
which may be made to the Premises by Lessee, including but not limited to, floor
coverings, panelings, doors, drapes, built-ins, moldings, sound attenuation, and
lighting and telephone or communication systems, conduit, wiring and outlets,
shall be made and done in a good and workmanlike manner and of good and
sufficient quality and materials and shall be the property of Lessor and remain
upon and be surrendered with the Premises at the expiration of the Lease term,
unless Lessor requires their removal pursuant to paragraph 7.3(a).
Notwithstanding the provisions of this paragraph 7.3(e), Lessee's personal
property and equipment, other than that which is affixed to the Premises so that
it cannot be removed without material damage to the Premises or the Building,
and other than Utility Installations, shall remain the property of Lessee and
may be removed by Lessee subject to the provisions of paragraph 7.2.

        (f)  Lessee shall provide Lessor with as-built plans and specifications
for any alterations, improvements, additions or Utility Installations.

        7.4      Utility Additions. Lessor reserves the right to install new or
additional utility facilities throughout the Office Building Project for the
benefit of Lessor or Lessee, or any other lessee of the Office Building Project,
including, but not by way of limitation, such utilities as plumbing, electrical
systems, security systems, communication systems, and fire protection and
detection systems, so long as such installations do not unreasonably interfere
with Lessee's use of the Premises.

8.      Insurance; Indemnity.

        8.1     Liability Insurance-Lessee. Lessee shall, at Lessee's expense,
obtain and keep in force during the term of this Lease a policy of
Comprehensive General Liability insurance utilizing an Insurance Services Office
standard form with Broad Form General Liability Endorsement (GL0404), or
equivalent, in an amount of not less than $1,000,000 per occurrence of bodily
injury and property damage combined or in a greater amount as reasonably
determined by Lessor and shall insure Lessee with Lessor as an additional
insured against liability arising out of the use, occupancy or maintenance of
the Premises. Compliance with the above requirement shall not, however, limit
the liability of Lessee hereunder.

        8.2     Liability Insurance-Lessor. Lessor shall obtain and keep in
force during the term of this Lease a policy of Combined Single Limit Bodily
injury and Broad Form Property Damage Insurance, plus coverage against such
other risks Lessor deems advisable from time to time, insuring Lessor, but not
Lessee, against liability arising out of the ownership, use, occupancy or
maintenance of the Office Building Project in an amount not less than
$5,000,000.00 per occurrence.

        8.3     Property Insurance-Lessee. Lessee shall, at Lessee's expense,
obtain and keep in force during the term of this Lease for the benefit of
Lessee, replacement cost fire and extended coverage insurance, with vandalism
and malicious mischief, sprinkler leakage and in an amount sufficient to cover
not less than 100% of the full replacement cost, as the same may exist from
time to time, of all of Lessee's personal property, fixtures, equipment and
tenant improvements.

        8.4     Property Insurance-Lessor. Lessor shall obtain and keep in force
during the term of this Lease a policy or policies of insurance covering loss or
damage to the Office Building Project improvements, but not Lessee's personal
property, fixtures, equipment or tenant improvements, in the amount of the full
replacement cost thereof, as the same may exist from time to time, utilizing
Insurance Services Office standard form, or equivalent, providing protection
against all perils included within the classification of fire, extended
coverage, vandalism, malicious mischief, plate glass, and such other perils as
Lessor deems advisable or may be required by a lender having a lien on the
Office Building Project. In addition, Lessor shall obtain and keep in force,
during the term of this Lease, a policy of rental value insurance covering a
period of one year, with loss payable to Lessor, which insurance shall also
cover all Operating Expenses for said period. Lessee will not be named in any
such policies carried by Lessor and shall have no right to any proceeds
therefrom. The policies required by these paragraphs 8.2 and 8.4 shall contain
such deductibles as Lessor or the aforesaid lender may determine. In the event
that the Premises shall suffer an insured loss as defined in paragraph 9.1(f)
hereof, the deductible amounts under the applicable insurance policies shall be
deemed an Operating Expense. Lessee shall not do or permit to be done anything
which shall invalidate the insurance policies carried by Lessor. Lessee shall
pay the entirety of any increase in the property insurance premium for the
Office Building Project over what it was immediately prior to the commencement
of the term of this Lease if the increase is specified by Lessor's insurance
carrier as being caused by the nature of Lessee's occupancy or any act or
omission of Lessee.

        8.5     Insurance Policies. Lessee shall deliver to Lessor copies of
liability insurance policies required under paragraph 8.1 or certificates
evidencing the existence and amounts of such insurance within seven (7) days
after the Commencement Date of this Lease. No such policy shall be canceliable
or subject to reduction of coverage or other material modification except after
thirty (30) days prior written notice to Lessor. Lessee shall, at least thirty
(30) days prior to the expiration of such policies furnish Lessor with renewals
thereof.

        8.6     Waiver of Subrogation. Lessee and Lessor each hereby release and
relieve the other, and waive their entire right of recovery against the other,
for direct or consequential loss or damage arising out of or incident to the
perils covered by property insurance carried by such party, whether due to the
negligence of Lessor or Lessee or their agents, employees, contractors and/or
invitees. If necessary all property insurance policies required under this Lease
shall be endorsed to so provide.

        8.7     Indemnity. Lessee shall indemnify and hold harmless Lessor and
its agents, Lessor's master or ground lessor, partners and lenders, from and
against any and all claims for damage to the person or property of anyone or any
entity arising from Lessee's use of the Office Building Project, or from the
conduct of Lessee's business or from any activity, work or things done,
permitted or suffered by Lessee in or about the Premises or elsewhere and shall
further indemnify and hold harmless Lessor from and against any and all claims,
costs and expenses arising from any breach or default in the performance of any
obligation on Lessee's part to be performed under the terms of this Lease, or
arising from any act or omission of Lessee, or any of Lessee's agents,
contractors, employees or invitees and from and against all costs, attorney's
fees, expenses and liabilities incurred by Lessor as the result of any such use,
conduct, activity, work, things done, permitted or suffered, breach, default or
negligence, and in dealing reasonably therewith, including but not limited to
the defense or pursuit of any claim or any action or proceeding involved
therein; and in case any action or proceeding be brought against Lessor by
reason of any such matter, Lessee upon notice from Lessor shall defend the same
at Lessee's expense by counsel reasonably satisfactory to Lessor and Lessor
shall cooperate with Lessee in such defense. Lessor need not have first paid any
such claim in order to be so indemnified. Lessee, as a material part of the
consideration to Lessor, hereby assumes all risk of damage to property of Lessee
or injury to persons, in, upon or about the Office Building Project arising from
any cause and Lessee hereby waives all claims in respect thereof against Lessor.

        8.8     Exemption of Lessor from Liability. Lessee hereby agrees that
Lessor shall not be liable for injury to Lessee's business or any loss of
income therefrom or for loss of or damage to the goods, wares, merchandise or
other property of Lessee, Lessee's employees, invitees, customers, or any other
person in or about the Premises or the Office Building Project, nor shall Lessor
be liable for injury to the person of Lessee, Lessee's employees, agents or
contractors, whether such damage or injury is caused by or results from theft,
fire, steam, electricity, gas, water or rain, or from the breakage, leakage,
obstruction or other defects of pipes, sprinklers, wires, appliances, plumbing,
air conditioning or lighting fixtures, or from any other cause, whether said
damage or injury results from conditions arising upon the Premises or upon other
portions of the Office Building Project, or from other sources or places, or
from new construction or the repair, alteration or improvement of any part of
the Office Building Project, or of the equipment, fixtures or appurtenances
applicable thereto, and regardless of whether the cause of such damage or injury
or the means of repairing the same is inaccessible. Lessor shall not be liable
for any damages arising from any act or neglect of any other lessee, occupant or
user of the Office Building Project, nor from the failure of Lessor to enforce
the provisions of any other lease of any other lessee of the Office Building
Project.

        8.9     No Representation of Adequate Coverage. Lessor makes no
representation that the limits or forms of coverage of insurance specified in
this paragraph 8 are adequate to cover Lessee's property or obligations under
this Lease.

or destroyed to any extent.

                (b)     "Premises Building Partial Damage" shall mean if the

that the cost to repair is less than fifty percent (50%) of the then Replacement
Cost of the Building.

                (c)     "Premises Building Total Destruction" shall mean if the
Building of which the Premises are a part is damaged or destroyed to the extent
that the cost to repair is fifty percent (50%) or more of the then Replacement
Cost of the Building.

necessary to be spent in order to repair or rebuild the damaged area to the
condition that existed immediately prior to the damage occurring, excluding all

reasonably possible and to the extent the required materials and labor are
readily available through usual commercial channels, at Lessor's expense, repair
such damage (but not Lessee's fixtures, equipment or tenant improvements
originally paid for by Lessee) to its condition existing at the time of the
damage, and this Lease shall continue in full force and effect.

                (b)     Uninsured Loss: Subject to the provisions of paragraph
9.4 and 9.5, if at any time during the term of this Lease there is damage which
is not an insured Loss and which falls within the classification of Premises
Damage or Premises Building Partial Damage, unless caused by a negligent or
willful act of Lessee (in which event Lessee shall make the repairs at Lessee's
expense), which damage prevents Lessee from making any substantial use of the
Premises, Lessor may at Lessor's option either (i) repair such damages as soon
as reasonably possible at Lessor's expense, in which event this Lease shall
continue in full force and effect, or (ii) give written notice to Lessee within
(30) days after the date of the occurrence of such damage of Lessor's intention
to cancel and terminate this Lease as of the date of the occurrence of such
damage, in which event this Lease shall terminate as of the date of the
occurrence of such damage.

Building Total Destruction, or (ii) Office Building Project Total Destruction,
than Lessor may at Lessor's option either (i) repair such damage or destruction
as soon as reasonably possible at Lessor's expense (to the extent the required
materials are readily available through usual commercial channels) to its
condition existing at the time of the damage, but not Lessee's fixtures,
equipment or tenant improvements, and this Lease shall continue in full force
and effect, or (ii) give written notice to Lessee within thirty (30) days after
the date of occurrence of such damage of Lessor's intention to cancel and
terminate this Lease, in which case this Lease shall terminate as of the date of
the occurrence of such damage.

    9.4  Damage Near End of Term.

         (a) Subject to paragraph 9.4(b), if at any time during the last twelve
(12) months of the term of this Lease there is substantial damage to the
Premises, Lessor may at Lessor's option cancel and terminate this Lease as of
the date of occurrence of such damage by giving written notice to Lessee of
Lessor's election to do so within 30 days after the date of occurrence of such
damage.

         (b) Notwithstanding paragraph 9.4(a), in the event that Lessee has an
option to extend or renew this Lease, and the time within which said option may
be exercised has not yet expired, Lessee shall exercise such option, if it is to
be exercised at all, no later than twenty (20) days after the occurrence of an
insured Loss failing within the classification of Premises Damage during the
last twelve (12) months of the term of this Lease. If Lessee duly exercises such
option during said twenty (20) day period, Lessor shall, at Lessor's expense,
repair such damage, but not Lessee's fixtures, equipment or tenant improvements,
as soon as reasonably possible and this Lease shall continue in full force and
effect. If Lessee fails to exercise such option during said twenty (20) day
period, then Lessor may at Lessor's option terminate and cancel this Lease as of
the expiration of said twenty (20) day period, notwithstanding any term or
provision in the grant of option to the contrary.

    9.5  Abatement of Rent; Lessee's Remedies.

         (a) In the event Lessor repairs or restores the Building or Premises
pursuant to the provisions of the paragraph 9, and any part of the Premises are
not usable (including loss of use due to loss of access or essential services),
the rent payable hereunder (including Lessee's Shares of Operating Expenses) 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 from 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.

         (b) If Lessor shall be obligated to repair or restore the Premises or
the Building under the provisions of this Paragraph 9 and shall not commence
such repair or restoration within ninety (90) days after such occurrence, or if
Lessor shall not complete the restoration and repair within six (6) months after
such occurrence, Lessee may at Lessee's option cancel and terminate this Lease
by giving Lessor written notice of Lessee's election to do so at any time prior
to the commencement or completion, respectively, of such repair or restoration.
In such event this Lease shall terminate as of the date of such notice.

         (c) Lessee agrees to cooperate with Lessor in connection with any such
restoration and repair, including but not limited to the approval and/or
execution of plans and specifications required.

    9.6  Termination-Advance Payments. Upon termination of this Lease pursuant
to this paragraph 9, an equitable adjustment shall be made concerning advance
rent and any advance payments made by Lessee to Lessor. Lessor shall, in
addition, return to Lessee so much of Lessee's security deposit as has not
theretofore been applied by Lessor.

    9.7  Waiver. Lessor and Lessee waive the provision of any statute which
relate to termination of leases when leased property is destroyed and agree that
such event shall be governed by the terms of this Lease.

10. Real Property Taxes.

    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,
special, 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 district thereof, as 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, levy, assessment or
charge (i) in substitution of, partially or totally, any tax, fee, levy,
assessment or charge hereinabove included within the definition of "real
property tax," or (ii) the nature of which was hereinbefore included within the
definition of "real property tax," or (iii) which is imposed for a service or
right not charged prior to June 1, 1978, 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 not
separately assessed, Lessee's portion of that tax shall be equitably determined
by Lessor from the respective valuations assigned in the assessor's work sheets
or such other information (which may include the cost of construction) as may be
reasonably available.

    10.5 Personal Property Taxes.

         (a) Lessee shall pay prior to delinquency all taxes assessed against
and levied upon trade fixtures, furnishings, equipment and all other personal
property of Lessee contained in the Premises or elsewhere.

         (b) If any of Lessee's said personal property shall be assessed with
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.

11. 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 metered
to the Premises, Lessee shall pay at Lessor's option, either Lessee's 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
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 in or about the Premises that uses excess water, lighting
or power, or suffer or permit any act that causes extra burden upon the
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 at Lessee's expense supplemental 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 discontinuance of any utility or service due to riot, strike, labor dispute,
breakdown, accident, repair or other cause beyond Lessor's reasonable control or
in cooperation with governmental request or directions.

12. Assignment and Subletting.

    12.1 Lessor's Consent Required. Lessee shall not voluntarily or by operation
of law assign, transfer, mortgage, sublet, or otherwise transfer or encumber 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, encumbrance or
subletting without such consent shall be void, and shall constitute default and
breach of this Lease. Lessee shall have cure rights for such default as
described under section 13.1. "Transfer" within the meaning of this paragraph 12
shall include the transfer or transfers aggregating: (a) If

                                                                Initials: KRD

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 Lessee Affiliate. 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 from 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 that is being
conducted on the Premises, all of which are referred to as "Lessee Affiliate";
provided that before such assignment shall be effective, (a) said assignee shall
assume, in full, the obligations of Lessee under this Lease and (b) Lessor shall
be given written notice of such assignment and assumption. Any such assignment
shall not, in any way, affect or limit the liability of Lessee under the terms
of this Lease even if after such assignment or subletting the terms of this
Lease are materially changed or altered without the consent of Lessee, the
consent of whom shall not be necessary.

     12.3 Terms and Conditions Applicable to Assignment and Subletting.

          (a) Regardless of Lessor's consent, no assignment or subletting shall
release Lessee of Lessee's obligations hereunder or alter the primary liability
of Lessee to pay the rent and other sums due Lessor hereunder including Lessee's
Share of Operating Expenses, and to perform all other obligations to be
performed by Lessee hereunder.

          (b) Lessor may accept rent from any person 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 estoppel
of Lessor's right to exercise its remedies 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 thereto,
shall not be effective unless said guarantors give their written consent to such
sublease and the terms thereof.

          (e) The consent by Lessor to any assignment or subletting shall not
constitute a consent to any subsequent assignment or subletting by Lessee or to
any subsequent or successive assignment or subletting by the sublessee. However,
Lessor may consent to subsequent sublettings and assignments of the sublease or
any amendments or modifications thereto without notifying Lessee or anyone else
liable on the Lease or sublease and without obtaining their consent and such
action shall not relieve such persons from liability under this Lease or said
sublease; provided, 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 such 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 the
performance of this Lease, including the sublessee, without first exhausting
Lessor's remedies against any other person or entity responsible therefor to
Lessor, or 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 then
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 constent null and void.

     12.4 Additional Terms and Conditions Applicable to Subletting. Regardless
or Lessor's consent, the following terms and conditions shall apply to any
subletting 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
hereafter 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 the 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 sublessee under such
sublease. Lessee hereby irrevocably authorizes and directs any such sublessee,
upon receipt of a written notice from Lessor stating 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 sublease. Lessee agrees that such
sublessee shall have the right to rely 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 Lessee 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 sublease 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 sublessee shall, by reason of entering into
a sublease under this Lease, be deemed, for the benefit of Lessor, to have
assumed and agreed to conform and comply with each and every obligation herein
to be performed by Lessee other than such obligations as are contrary to or
inconsistent with provisions contained in a sublease to 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.

          (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 or if
Lessee shall request the consent of Lessor for any act Lessee proposes to do
then Lessee shall pay Lessor's reasonable costs and expenses incurred in
connection therewith, including attorneys', architects', engineers' or other
consultants' fees.

     12.6 Conditions to 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 of 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
or subletting, whichever is greater.

13.  Default; Remedies.

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

          (a) Or abandonment of the Premises by Lessee.

SEE PARAGRAPH 50.

          (c) The failure by Lessee to make any payment of rent or any other
payment to be made by Lessee hereunder, as and when due, where such failure
shall continue for a period of three (3) days after written notice therof 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.

          (d) The failure by Lessee to observe or perfom any of the covenants,
conditions or provisions of this Lesse to be observed or performed by Lessee
other than those referenced in subparagraphs (a), (b), (c), and (e), above,
where such failure shall continue for a period of thirty (30) 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 thereafter
diligently pursues such cure to completion. To the extent permitted by law, such
thirty (30) day notice shall constitute the sole and exclusive notice required

of a petition filed against Lessee, the same is dismissed within sixty (60)

          (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
obligation hereunder, was intentionally 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 or demand
and without limiting Lessor in the exercise of any right or 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.

          (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's
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 late payment by Lessee
to Lessor of Base Rent, Lessee's Share of Operating Expenses 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, 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, then, without any requirement for notice to Lessee, Lessee shall
pay to Lessor a late charge equal to 6% of such overdue amount. The parties
hereby agree that such late charge represents a fair and reasonable estimate of
the costs Lessor will incur by reason of late payment by Lessee. Acceptance of
such late charge by Lessor shall in no 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.

14. 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 are taken by such
condemnation as would 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 Expenses 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 taken 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 payment made
under threat of the exercise of such power shall be the property of Lessor,
whether such award shall be made as compensation for diminution 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 award 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 therefor by the condemning authority. Lessee shall pay any amount in
excess of such severance damages required to complete such repair.

15. Broker's Fee.

          (a) The brokers involved in this transaction are N/A as "listing
                                                           ---
broker" and N/A as "cooperating broker," licensed real estate broker(s). A
            ---
"cooperating broker" is defined as any broker other than the listing broker
entitled to a share of any commission arising 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 $
N/A, 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 subsequently granted option which is substantially similar to an
Option granted to Lessee under this Lease, or (ii) if Lessee acquires any 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 having 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 or operation of 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 fee 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, whether
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 arising 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 dealings 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 any dealings or actions of the indemnifying
party.

16. 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 to
which the rent and other charges are paid in advance, if any, and (ii)
acknowledging that there are not, to the responding party's knowledge, any
uncured defaults 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 and after notice has been given as outlined in
50(ii), shall be a material default of this Lease by the party who is 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, without
modification except as may be represented by the requesting party, (ii) there
are no uncured defaults in the requesting party's performance, and (iii) if
Lessor is the requesting party, not more than one month's 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 or purchaser designated by Lessor such financial statements of Lessee as
may be reasonably required by such lender or purchaser. Such statements shall
include the past three (3) years' financial statements of Lessee. All such
financial statements shall be received by Lessor and such lender or purchaser in
confidence and shall be used only for the purpose herein set forth.

17. Lessor's 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
or interest. Lessor herein named (and in case of any subsequent transfers than
the grantor) shall be relieved from and after the date of such transfer of all
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 the Lease to be performed by Lessor shall, subject
as aforesaid, be binding on Lessor's successors and assigns, only during their
respective periods of ownership.

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

19. Interest on Past-due Obligations. Except as expressly herein provided, any
amount due to Lessor not paid when due shall bear interest at the maximum 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.

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

21. 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 and any other expenses payable by Lessee hereunder shall be deemed to be
rent.

22. Incorporation of Prior Agreements; Amendments. This Lease contains all
agreements of the parties with respect to any matter mentioned herein. No prior
or contemporaneous agreement or understanding pertaining to any such matter
shall be effective. This Lease may be modified in writing only; signed by the
parties in interest at the time of the modification. Except as otherwise stated
in this Lease, Lessee hereby acknowledges that neither the real estate broker
listed in paragraph 15 hereof nor any cooperating broker on this transaction nor
the Lessor or any employee or agents of any of said persons has made any oral or
written warranties or representations to Lessee relative to the condition or
use by Lessee of the Premises or the Office Building Project and Lessee
acknowledges that Lessee assumes all responsibility regarding the Occupational
Safety Health Act, the legal use and adaptability of the Premises and the
compliance thereof with all applicable laws and regulations in effect during the
term of this Lease.

23. 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 signature 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 notice purposes except
that upon Lessee's taking possession of the Premises, the Premises shall
constitute Lessee's address for notice purposes. A copy of all notices required
or permitted to be given to Lessor hereunder shall be concurrently transmitted
to such party or parties at such addresses as Lessor may from time to time
hereafter designate by notice of Lessee.

24. 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 such preceding breach at the time of
acceptance of such rent.

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

26. 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, such
occupancy shall be a tenancy from month to month upon all the provisions of
this Lease pertaining to the obligations of Lessee, except that the rent payable
shall be two hundred percent (200%) of the rent payable immediately preceding
the termination date of this Lease, and all Options, if any, granted under the
terms of this Lease shall be deemed terminated and be of no further effect
during said month to month tenancy.

27. 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.

28. Covenants and Conditions. Each provision of this Lease performable by Lessee
shall be deemed both a covenant and a condition.

29. 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 the State
where the Office Building Project is located and any litigation concerning this
Lease between the parties hereto shall be initiated in the country in which the
Office Building Project is located.

30. Subordination.

    (a) This Lease, and any Option or right of first refusal granted hereby, at
Lessor's option, shall be subordinate to any ground lease, mortgage, deed or
trust, or any other hypothecation or security now or hereafter placed upon the
Office Building Project and to any and all advances made on the 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 observe and perform all of the provisions of
this Lease, unless this Lease is otherwise terminated pursuant to its terms. If
any mortgagee, trustee or ground lessor shall elect to have this Lease and any
Options granted hereby prior to the lien of its mortgage, deed of trust or
ground lease, and shall give written notice thereof to Lessee, this Lease and
such Options shall be deemed prior to such mortgage, deed of trust or ground
lease, whether this 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 herein
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, constitute and irrevocably appoint Lessor as Lessee's attorney-in-fact and
in Lessee's name, place and stead, to execute such documents in accordance with
this paragraph 30(b).

31. Attorney's Fees.

    31.1 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
any 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 same
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.

    31.2 The attorneys' fees 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.

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

32. Lessor's Access.

    32.1 Lessor and Lessor's agents shall have the right to enter the Premises
at reasonable times for the purpose of inspecting the same, performing any
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 as 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 time during the last 120 days of
the term hereof place on or about the Premises any ordinary "For Lease" signs.

    32.2 All activities of Lessor pursuant to this paragraph shall be without
abatement of rent, nor shall Lessor have any liability to Lessee 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 the Premises or an eviction. Lessee waives any charges for damages
or injuries or interference with Lessee's property or business in connection
therewith.

33. Auctions. Lessee shall not conduct, nor permit to be conducted, either
voluntarily or involuntarily, any auction upon the Premises of 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.

34. 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.

                                                               Initials:  KRD

35. Merger. The voluntary or other surrender of this Lease by Lessee, or a
mutual cancellation thereof, or a termination by Lessor, shall not work 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.

36. 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 reasonably withheld or delayed.

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

38. 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
following meaning: (1) the right or option to extend the term of this Lease or
to renew this Lease or to extend or renew any lease that Lessee has on other
property of Lessor; (2) the option or right of first refusal to lease the
Premises or the right of first offer to lease the Premises or the right of first
refusal to lease other space within the Office Building Project or other
property of Lessor or the right of first offer to lease other space within the
Office Building Project or other property of Lessor; (3) the right or option to
purchase the Premises or the Office Building Project, or the right of first
refusal to purchase the Premises or the Office Building Project or the right of
first offer to purchase the Premises or the Office Building Project, or the
right or option to purchase other property of Lessor, or the right of first
refusal to purchase other property of Lessor or the right of first offer to
purchase other property of Lessor.

    39.2 Options Personal. Each Option granted to Lessee in this Lease is
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 an 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 a part 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 the prior
option to extend or renew this Lease has been so exercised.

    39.4 Effect of Default on Options.

        (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 alleged 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 terms, covenants or conditions of this Lease.

        (b) The period of time within which an Option may be exercised shall not
be extended or enlarge by reason of Lessee's inability to exercise an 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

    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

from providing security protection for the Office Building Project or any part
thereof, in which event the cost thereof shall be included within the definition
of Operating Expenses, as set forth in paragraph 4.2(b).

    40.2 Lessor shall have the following rights:

long as such exclusive does not conflict with any rights expressly given herein;

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

    40.3 Lessee shall not:

        (a) Use a representation (photographic or otherwise) of the Building or

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 unreasonably
interfere with the use of the Premises by Lessee. Lessee shall sign any of the
aforementioned documents upon request of Lessor.

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.

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 regarded as a voluntary payment, and there shall survive the right on the
part of said party to institute suit for recovery of such sum. If it shall be
adjudged that there was no legal obligation on the part of said party to pay
such sum or any part thereof, said party shall be entitled to recover such sum
or so much thereof as it was not legally required to pay under the provisions of
this Lease.

43. Authority. If Lessee is a corporation, trust, or general or limited
partnership, Lessee, and each individual executing this Lease on behalf of such
entity, represent and warrant that such individual is duly authorized to execute
and deliver this Lease on behalf of said entity. If Lessee is a corporation,
trust or partnership, Lessee shall, within thirty (30) days after execution of
this Lease, deliver to Lessor evidence of such authority satisfactory to Lessor.

44. Conflict. Any conflict between the printed provisions, Exhibits or Addenda
of this Lease and the typewritten or handwritten provisions, if any, shall be
controlled by the typewritten or handwritten provisions.

45. No Offer. Preparation of this Lease by Lessor or Lessor's agent and
submission of same to Lessee shall not be deemed an offer to Lessee to lease.
This Lease shall become binding upon Lessor and Lessee only when fully executed
by both parties.

46. Lender Modification. Lessee agrees to make such reasonabe modifications to
this Lease as may be reasonably required by an institutional lender in
connection with the obtaining of normal financing or refinancing of the Office
Building Project.

                              RIGHT OF FIRST OFFER
                            TO LEASE ADJACENT SPACE

     This RIDER NO. 1 is attached to and incorporated into that certain
"Standard Office Lease (Tenant)" dated March 16, 2000 (the Lease), between GVE
Distel Associates, a California General Partnership ("Landlord") and R2
Technology, Inc., a California Corporation ("Tenant"), for the Premises known as
730 Distel Drive, Los Altos California. The capitalized terms used and not
otherwise defined herein shall have the same definitions as set forth in the
Lease. The provisions of this Lease Rider shall supersede any inconsistent or
conflicting provisions of the Lease.

     Provided no Event of Default has occurred and is continuing, if rentable
space within the Building adjacent to the Premises located at 333 Distel Circle
in the approximate amount of 16,227 square feet ("Adjacent Space") shall become
available for leasing by other than the existing tenant(s), said Adjacent Space
shall be made available to Tenant to lease, one (1) time only, upon the terms
and conditions hereinafter set forth ("Right to First Offer"). If at any time
during the Term of the Lease any Adjacent Space becomes available, Landlord
shall prior to making the Adjacent Space available to other third parties, first
deliver written notice of such availability to Tenant and the terms upon which
Landlord is willing to lease such space to Tenant ("Landlord Notice"). The
rental rate shall be at the then current market rate for office space in the Los
Altos/Palo Alto market for space leased to other tenant's of similar credit
worthiness as Tenant. For a period of three (3) business days following Tenant's
receipt of Landlord's Notice, Tenant shall have the first opportunity to lease
the Adjacent Space upon the terms and conditions set forth in Landlord's Notice
by delivering to Landlord within said three (3) business day period written
notice ("Election Notice") of its election to exercise its Right of First Offer.
If Tenant fails or elects not to exercise its Right of First Offer granted
pursuant to this paragraph within said three (3) business day period, the Right
of First Offer shall automatically terminate without further action of the
parties, and Landlord shall be free to lease the Adjacent Space to any third
party upon such terms and conditions as Landlord desired. If Tenant timely and
properly exercises its Right of First Offer as hereinabove provided, Tenant
shall, within five (5) days after receipt from Landlord, enter into a new lease
with Landlord upon Landlord's then current standard lease form for the Building,
which new lease incorporates the terms set forth in Landlord's Notice with
respect to the Adjacent Space. If Tenant fails to execute and deliver such new
lease within said five (5) day period, the Right for First Offer shall
automatically terminate without further action of the parties, and Landlord
shall be thereafter free to lease the Adjacent Space to any third party upon
such terms and conditions as Landlord desires.

     Tenant's Right of First Offer is personal to Tenant and may not be
exercised by or assigned to any person or entity other than Tenant, and shall
terminate and be of no further force or effect upon any assignment of the Lease
or subletting of the Premises.
