                             "D" - Estoppel Certificate Form
<PAGE>

2.   Premises.  Landlord hereby leases to Tenant and Tenant hereby leases from
     --------
Landlord the Premises as shown on attached Exhibit "A" within the Building (the
Building and the lot on which it is located, the "PROPERTY"), together with the
nonexclusive right with Landlord and other occupants of the Building to use all
areas and facilities provided by Landlord for the use of all tenants in the
Property including any driveways, sidewalks and parking, loading and landscaped
areas (the "COMMON AREAS").

3.   Acceptance of Premises.  Tenant has examined and knows the condition of the
     ----------------------
Property, the zoning, streets, sidewalks, parking areas, curbs and access ways
adjoining it, visible easements, any surface conditions and the present uses,
and Tenant accepts them in the condition in which they now are, without relying
on any representation, covenant or warranty by Landlord. Tenant and its agents
shall have the right, at Tenant's own risk, expense and responsibility, at all
reasonable times prior to the Commencement Date, to enter the Premises for the
purpose of taking measurements and installing its furnishings and equipment;
provided that the Premises are vacant and Tenant obtains Landlord's prior
written consent.

4.   Use; Compliance.
     ---------------

          (a)  Permitted Use. Tenant shall occupy and use the Premises for and
only for the Use specified in Section l(f) above and in such a manner as is
lawful, reputable and will not create any nuisance or otherwise interfere with
any other tenant's normal operations or the management of the Building. Without
limiting the foregoing, such Use shall exclude any use that would cause the
Premises or the Property to be deemed a "place of public accommodation" under
the Americans with Disabilities Act (the "ADA") as further described in the
Building Rules (defined below). All Common Areas shall be subject to Landlord's
exclusive control and management at all times. Tenant shall not use or permit
the use of any portion of the Property for outdoor storage or installations
outside of the Premises nor for any use that would interfere with any other
person's use of any portion of the Property outside of the Premises.

          (b)  Compliance. Landlord represents that, as of the date of this
lease, there is no action required with respect to the Premises or Common Areas
under any laws (including Title III of the ADA), ordinances, notices, orders,
rules, regulations and requirements applicable to the Premises or to the Common
Areas. From and after the Commencement Date, Tenant shall comply promptly, at
its sole expense, (including making any alterations or improvements) with all
laws (including the ADA), ordinances, notices, orders, rules, regulations and
requirements regulating the Property during the Term which impose any duty upon
Landlord or Tenant with respect to Tenant's use, occupancy or alteration of, or
Tenant's installations in or upon, the Property including the Premises, (as the
same may be amended, the "LAWS AND REQUIREMENTS") and the building rules
attached as Exhibit "C", as amended by Landlord from time to time (the "BUILDING
RULES"). Provided, however, that Tenant shall not be required to comply with the
Laws and Requirements with respect to the footings, foundations, structural
steel columns and girders forming a part of the Property unless the need for
such compliance arises out of Tenant's use, occupancy or alteration of the
Property, or by any act or omission of Tenant or any employees, agents,
contractors, licensees or invitees ("AGENTS") of Tenant. With respect to
Tenant's obligations as to the Property, other than the Premises, at Landlord's
option and at Tenant's expense, Landlord may comply with any repair, replacement
or other construction requirements of the Laws and Requirements and Tenant shall
pay to Landlord all costs thereof as additional rent.

          (c)  Environmental. Tenant shall comply, at its sole expense, with all
Laws and Requirements as set forth above, all manufacturers' instructions and
all requirements of insurers relating to the treatment, production, storage,
handling, transfer, processing, transporting, use, disposal and release of
hazardous substances, hazardous fixtures, chemicals, pollutants, petroleum
products, toxic or radioactive matter (the "RESTRICTED ACTIVITIES"). Tenant
shall deliver to Landlord copies of all Material Safety Data Sheets or other
written information prepared by manufacturers, importers or suppliers of any
chemical and all notices, filings, permits and any other written communications
from or to Tenant and any entity regulating any Restricted Activities.

          (d)  Notice. If at any time during or after the Term, Tenant becomes
aware of any inquiry, investigation or proceeding regarding the Restricted
Activities or becomes aware of any claims, actions or investigations regarding
the ADA, Tenant shall give Landlord written notice, within 5 days after first
learning thereof, providing all available information and copies of any notices.

5.   Term.  The Term of this lease shall commence on the Commencement Date and
     ----
shall end at 11:59 p.m. on the last day of the Term (the "EXPIRATION DATE"),
without the necessity for notice from either party, unless sooner terminated in
accordance with the terms hereof. At Landlords request, Tenant shall confirm the
Commencement Date and Expiration Date by executing a lease commencement
certificate in the form attached as Exhibit "B".

6.   Minimum Annual Rent.  Tenant agrees to pay to Landlord the Minimum Annual
     -------------------
Rent in equal monthly installments in the amount set forth in Section l(d) (as
increased at the beginning of each lease year as set forth in Section 1(d)), in
advance, on the first day of each calendar month during the Term, without
notice, demand or setoff, at Landlord's address designated at the beginning of

                                       2
<PAGE>

this lease unless Landlord designates otherwise; provided that rent for the
first full month shall be paid at the signing of this lease. If the Commencement
Date falls on a day other than the first day of a calendar month, the rent shall
be apportioned pro rata on a per diem basis for the period from the Commencement
Date until the first day of the following calendar month and shall be paid on or
before the Commencement Date. As used in this lease, the term "lease year" means
the period from the Commencement Date through the succeeding 12 full calendar
months (including for the first lease year any partial month from the
Commencement Date until the first day of the first full calendar month) and each
successive 12 month period thereafter during the Term.

7.   Operation of Property, Payment of Expenses.
     ------------------------------------------

          (a)  Payment of Operating Expenses. Tenant shall pay to Landlord the
Annual Operating Expenses in equal monthly installments in the amount set forth
in Section l(d) (prorated for any partial month), from the Commencement Date and
continuing throughout the Term on the first day of each calendar month during
the Term, as additional rent, without notice, demand or setoff; provided that
the monthly installment for the first full month shall be paid at the signing of
this lease. Landlord shall apply such payments to the operating expenses owed to
Landlord by Tenant pursuant to the following Sections 7(b)-(f). The amount of
the Annual Operating Expenses set forth in Section l(d) represents Tenant's
Proportionate Share of the estimated operating expenses during the first
calendar year of the Term on an annualized basis; from time to time Landlord may
adjust such estimated amount if the estimated operating expenses increase. By
April 30th of each year (and as soon as practical after the expiration or
termination of this lease or at any time in the event of a sale of the
Property), Landlord shall provide Tenant with a statement of the actual amount
of such expenses for the preceding calendar year or part thereof. Landlord or
Tenant shall pay to the other the amount of any deficiency or overpayment then
due from one to the other or, at Landlord's option, Landlord may credit Tenant's
account for any overpayment. Tenant's obligation to pay the Annual Operating
Expenses pursuant to this Section 7 shall survive the expiration or termination
of this lease.

          (b)  Taxes and Other Impositions. Tenant shall pay prior to
delinquency all levies, taxes (including sales taxes and gross receipt taxes),
assessments, liens, license and permit fees, which are applicable to the Term,
and which are imposed by any authority or under any law, ordinance or regulation
thereof, or pursuant to any recorded covenants or agreements, and the reasonable
cost of contesting any of the foregoing (the "IMPOSITIONS") upon or with respect
to the Premises, or any, improvements thereto, or directly upon this lease or
the Rent (defined in Section 7(f)) or amounts payable by any subtenants or other
occupants of the Premises, or against Landlord because of Landlord's estate or
interest herein. Additionally, Tenant shall pay as aforesaid its Proportionate
Share of any Imposition which is not imposed upon the Premises as a separate
entity but which is imposed upon all or part of the Property or upon the leases
or rents relating to the Property.

                  (i)   Nothing herein contained shall be interpreted as
requiring Tenant to pay any income, excess profits or corporate capital stock
tax imposed or assessed upon Landlord, unless such tax or any similar tax is
levied or assessed in lieu of all or any part of any Imposition or an increase
in any Imposition.

                  (ii)  If it shall not be lawful for Tenant to reimburse
Landlord for any of the Impositions, the Minimum Annual Rent shall be increased
by the amount of the portion of such Imposition allocable to Tenant, unless
prohibited by law.

          (c)  Insurance.

                  (i)   Property. Landlord shall keep in effect, and Tenant
shall pay to Landlord its Proportionate Share of the cost of, insurance against
loss or damage to the Building or the Property by fire and such other casualties
as may be included within fire, extended coverage and special form insurance
covering the full replacement cost of the Building (but excluding coverage of
Tenant's personal property in, and any alterations by Tenant to, the Premises),
and such other insurance as Landlord may reasonably deem appropriate or as may
be required from time-to-time by any mortgagee.

                  (ii)  Liability. Tenant, at its own expense, shall keep in
effect comprehensive general public liability insurance with respect to the
Premises and the Property, including contractual liability insurance, with such
limits of liability for bodily injury (including death) and property damage as
reasonably may be required by Landlord from time-to-time, but not less than a
combined single limit of $1,000,000 per occurrence and a general aggregate limit
of not less than $3,000,000 (which aggregate limit shall apply separately to
each of Tenant's locations if more than the Premises); however, such limits
shall not limit the liability of Tenant hereunder. The policy of comprehensive
general public liability insurance also shall name Landlord and Landlord's agent
as insured parties with respect to the Premises, shall be written on an
"occurrence" basis and not on a "claims made" basis, shall provide that it is
primary with respect to any policies carried by Landlord and that any coverage
carried by Landlord shall be excess insurance, shall provide that it shall not
be cancelable or reduced without at least 30 days prior written notice to
Landlord and shall be issued in form satisfactory to Landlord. The insurer shall
be a responsible insurance carrier which is authorized to issue such insurance
and licensed to do business in the state in which the Property is located and
which has at all times during the Term a rating of no less than A vii in the
most current edition of Rest's Insurance Reports. Tenant shall deliver to
Landlord on or before the

                                       3
<PAGE>

Commencement Date, and subsequently renewals of, a certificate of insurance
evidencing such coverage and the waiver of subrogation described below.

                  (iii)  Waiver of Subrogation. Landlord and Tenant shall have
included in their respective property insurance policies waivers of their
respective insurers' right of subrogation against the other party. If such a
waiver should be unobtainable or unenforceable, then such policies of insurance
shall state expressly that such policies shall not be invalidated if, before a
casualty, the insured waives the right of recovery against any party responsible
for a casualty covered by the policy.

                  (iv)   Increase of Premiums. Tenant agrees not to do anything
or fail to do anything which will increase the cost of Landlord's insurance or
which will prevent Landlord from procuring policies (including public liability)
from companies and in a form satisfactory to Landlord. If any breach of the
preceding sentence by Tenant causes the rate of fire or other insurance to be
increased, Tenant shall pay the amount of such increase as additional rent
promptly upon being billed.

          (d)  Repairs and Maintenance; Common Areas; Building Management.
Except as specifically otherwise provided in this Section (d), Tenant at its
sole expense shall maintain the Premises in good order and condition, promptly
make all repairs necessary to maintain such condition, and repair any damage to
the Premises caused by Tenant or its Agents. All repairs made by Tenant shall
utilize materials and equipment which are comparable to those originally used in
constructing the Building and Premises. When used in this Section (d), the term
"repairs" shall include replacements and renewals when necessary.

                  (i)    Landlord, at its sole expense, shall make all necessary
repairs to the footings, foundations, structural steel columns and girders
forming a part of the Premises, provided that Landlord shall have no
responsibility to make any repair until Landlord receives written notice of the
need for such repair.

                  (ii)   Landlord, at Tenant's sole expense, shall maintain and
repair the HVAC systems appurtenant to the Premises.

                  (iii)  Landlord shall make all necessary repairs to the roof,
exterior portions of the Premises and the Building, utility and communications
lines, equipment and facilities in the Building, which serve more than one
tenant, and to the Common Areas, the cost of which shall be an operating expense
of which Tenant shall pay its Proportionate Share, provided that Landlord shall
have no responsibility to make any repair until Landlord receives written notice
of the need for such repair. Landlord shall operate and manage the Property and
shall maintain all Common Areas and any paved areas appurtenant to the Property
in a clean and orderly condition. Landlord reserves the right to make
alterations to the Common Areas from time to time. Operating expenses also shall
include (A) all sums expended by Landlord for the supervision, maintenance,
repair, replacement and operation of the Common Areas (including the costs of
utility services), (B) any costs of building improvements made by Landlord to
the Property that are required by any governmental authority or for the purpose
of reducing operating expenses and (C) a management and administrative fee
applicable to the overall operation of the Property.

                  (iv)   Notwithstanding anything herein to the contrary,
repairs and replacements to the Property including the Premises made necessary
by Tenant's use, occupancy or alteration of, or Tenant's installation in or upon
the Property or by any act or omission of Tenant or its Agents shall be made at
the sole expense of Tenant to the extent not covered by any applicable insurance
proceeds paid to Landlord. Tenant shall not bear the expense of any repairs or
replacements to the Property arising out of or caused by any other tenant's use,
occupancy or alteration of, or any other tenant's installation in or upon, the
Property or by any act or omission of any other tenant or any other tenant's
Agents.

          (e)  Utility Charges. Tenant shall pay for water, sewer, gas,
electricity, heat, power, telephone and other communication services and any
other utilities supplied to or consumed in or on the Premises. Landlord shall
not be responsible or liable for any interruption in utility service, nor shall
such interruption affect the continuation or validity of this lease.

          (f)  Net lease. Except for the obligations of Landlord expressly set
forth herein, this lease is a "triple net lease" and Landlord shall receive the
Minimum Annual Rent as net income from the Premises, not diminished by any
expenses other than payments under any mortgages, and Landlord is not and shall
not be required to render any services of any kind to Tenant. The term "RENT" as
used in this lease means the Minimum Annual Rent, Annual Operating Expenses and
any other additional rent or sums payable by Tenant to Landlord pursuant to this
lease, all of which shall be deemed rent for purposes of Landlord's rights and
remedies with respect thereto. Tenant shall pay all Rent to Landlord within 30
days after Tenant is billed, unless otherwise provided in this lease, and
interest shall accrue on all sums due but unpaid.

8.   Signs. Except for signs which are located wholly within the interior of the
     -----
Premises and not visible from the exterior of the Premises, no signs shall be
placed on the Property without the prior written consent of Landlord. All signs
installed by Tenant shall

                                       4
<PAGE>

be maintained by Tenant in good condition and Tenant shall remove all such signs
at the termination of this lease and shall repair any damage caused by such
installation, existence or removal.

9.   Alterations and Fixtures.
     ------------------------

          (a)  Subject to Section 10, Tenant shall have the right to install its
trade fixtures in the Premises, provided that no such installation or removal
thereof shall affect any structural portion of the Property nor any utility
lines, communications lines, equipment or facilities in the Building serving any
tenant other than Tenant. At the expiration or termination of this lease and at
the option of Landlord or Tenant, Tenant shall remove such installation(s) and,
in the event of such removal, Tenant shall repair any damage caused by such
installation or removal; if Tenant, with Landlord's written consent, elects not
to remove such installation(s) at the expiration or termination of this lease,
all such installations shall remain on the Property and become the property of
Landlord without payment by Landlord.

          (b)  Except for non-structural changes which do not exceed $5000 in
the aggregate, Tenant shall not make or permit to be made any alterations to the
Premises without Landlord's prior written consent. Tenant shall pay the costs of
any required architectural engineering reviews. In making any alterations, (i)
Tenant shall deliver to Landlord the plans, specifications and necessary
permits, together with certificates evidencing that Tenant's contractors and
subcontractors have adequate insurance coverage naming Landlord and Landlord's
agent as additional insureds, at least 10 days prior to commencement thereof,
(ii) such alterations shall not impair the structural strength of the Building
or any other improvements or reduce the value of the Property or affect any
utility lines, communications lines, equipment or facilities in the Building
serving any tenant other than Tenant, (iii) Tenant shall comply with Section 10
and (iv) the occupants of the Building and of any adjoining property shall not
be disturbed thereby. All alterations to the Premises by Tenant shall be the
property of Tenant until the expiration or termination of this lease; at that
time all such alterations shall remain on the Property and become the property
of Landlord without payment by Landlord unless Landlord gives written notice to
Tenant to remove the same, in which event Tenant will remove such alterations
and repair any resulting damage. At Tenant's request prior to Tenant making any
alterations, Landlord shall notify Tenant in writing, whether Tenant is required
to remove such alterations at the expiration or termination of this lease.

10.  Mechanics' Liens.  Tenant shall pay promptly any contractors and
     ----------------
materialmen who supply labor, work or materials to Tenant at the Property and
shall take all steps permitted by law in order to avoid the imposition of any
mechanic's lien upon all or any portion of the Property. Should any such lien or
notice of lien be filed for work performed for Tenant other than by Landlord,
Tenant shall bond against or discharge the same within 5 days after Tenant has
notice that the lien or claim is filed regardless of the validity of such lien
or claim. Nothing in this lease is intended to authorize Tenant to do or cause
any work to be done or materials to be supplied for the account of Landlord, all
of the same to be solely for Tenant's account and at Tenant's risk and expense.
Throughout this lease the term "mechanic's lien" is used to include any lien,
encumbrance or charge levied or imposed upon all or any Portion of, interest in
or income from the Property on account of any mechanic's, laborer's,
materialman's or construction lien or arising out of any debt or liability to or
any claim of any contractor, mechanic, supplier, materialman or laborer and
shall include any mechanic's notice of intention to file a lien given to
Landlord or Tenant, any stop order given to Landlord or Tenant, any notice of
refusal to pay naming Landlord or Tenant and any injunctive or equitable action
brought by any person claiming to be entitled to any mechanic's lien.

11.  Landlord's Right of Entry.  Tenant shall permit Landlord and its Agents to
     -------------------------
enter the Premises at all reasonable times following reasonable notice (except
in the event of an emergency), for the purpose of inspection, maintenance or
making repairs, alterations or additions as well as to exhibit the Premises for
the purpose of sale or mortgage and, during the last 12 months of the Term, to
exhibit the Premises to any prospective tenant. Landlord will make reasonable
efforts not to inconvenience Tenant in exercising the foregoing rights, but
shall not be liable for any loss of occupation or quiet enjoyment thereby
occasioned.

12.  Damage by Fire or Other Casualty.
     --------------------------------

          (a)  If the Premises or Building shall be damaged or destroyed by fire
or other casualty, Tenant promptly shall notify Landlord and Landlord, subject
to the conditions set forth in this Section 12, shall repair such damage and
restore the Premises to substantially the same condition in which they were
immediately prior to such damage or destruction, but not including the repair,
restoration or replacement of the fixtures or alterations installed by Tenant.
Landlord shall notify Tenant in writing, within 30 days after the date of the
casualty, if Landlord anticipates that the restoration will take more than 180
days from the date of the casualty to complete; in such event, either Landlord
or Tenant may terminate this lease effective as of the date of casualty by
giving written notice to the other within 10 days after Landlord's notice.
Further, if a casualty occurs during the last 12 months of the Term or any
extension thereof, Landlord may cancel this lease unless Tenant has the right to
extend the Term for at least 3 more years and does so within 30 days after the
date of the casualty.

          (b)  Landlord shall maintain a 12 month rental coverage endorsement or
other comparable form of coverage as part of its fire. extended coverage and
special form insurance. Tenant will receive an abatement of its Minimum Annual
Rent and Annual Operating Expenses to the extent the Premises are rendered
untenantable as determined by the carrier providing the rental coverage
endorsement.

13.  Condemnation.
     ------------

          (a)  Termination. If (i) all of the Premises are taken by a
condemnation or otherwise for any public or quasi-public use, (ii) any part of
the Premises is so taken and the remainder thereof is insufficient for the
reasonable operation of Tenant's business or (iii) any of the Property is so
taken, and, in Landlords opinion, it would be impractical or the condemnation
proceeds are insufficient to restore the remainder of the Property, then this
lease shall terminate and all unaccrued obligations hereunder shall cease as of
the day before possession is taken by the condemnor.

          (b)  Partial Taking. If there is a condemnation and this lease has not
been terminated pursuant to this Section, (i) Landlord shall restore the
Building and the improvements which are a part of the Premises to a condition
and size as nearly comparable as reasonably possible to the condition and size
thereof immediately prior to the date upon which the condemnor took possession
and (ii) the obligations of Landlord and Tenant shall be unaffected by such
condemnation except that there shall be an equitable abatement of the Minimum
Annual Rent according to the rental value of the Premises before and after the
date upon which the condemnor took possession and/or the date Landlord completes
such restoration.

          (c)  Award. In the event of a condemnation affecting Tenant, Tenant
shall have the right to make a claim against the condemnor for moving expenses
and business dislocation damages to the extent that such claim does not reduce
the sums otherwise payable by the condemnor to Landlord. Except as aforesaid and
except as set forth in (d) below, Tenant hereby assigns all claims against the
condemnor to Landlord.

          (d)  Temporary Taking. No temporary taking of the Premises shall
terminate this lease or give Tenant any right to any rental abatement. Such a
temporary taking will be treated as if Tenant had sublet the Premises to the
condemnor and had assigned the proceeds of the subletting to Landlord to be
applied on account of Tenant's obligations hereunder. Any award for such a
temporary taking during the Term shall be applied first, to Landlord's costs of
collection and, second, on account of sums owing by Tenant hereunder, and if
such amounts applied on account of sums owing by Tenant hereunder should exceed
the entire amount owing by Tenant for the remainder of the Term, the excess will
be paid to Tenant.

14.  Non-Abatement of Rent.  Except as otherwise expressly provided as to damage
     ---------------------
by fire or other casualty in Section 12(b) and as to condemnation in Section
13(b), there shall be no abatement or reduction of the Rent for any cause
whatsoever, and this lease shall not terminate, and Tenant shall not be entitled
to surrender the Premises.

15.  Indemnification of Landlord.  Subject to Sections 7(c)(iii) and 16, Tenant
     ---------------------------
will protect, indemnify and hold harmless Landlord and its Agents from and
against any and all claims, actions, damages, liability and expense (including
fees of attorneys, investigators and experts) in connection with loss of life,
personal injury or damage to property in or about the Premises or arising out of
the occupancy or use of the Premises by Tenant or its Agents or occasioned
wholly or in part by any act or omission of Tenant or its Agents, whether prior
to, during or after the Term, except to the extent such loss, injury or damage
was caused by the negligence of Landlord or its Agents. In case any action or
proceeding is brought against Landlord and/or its Agents by reason of the
foregoing, Tenant, at its expense, shall resist and defend such action or
proceeding, or cause the same to be resisted and defended by counsel (reasonably
acceptable to Landlord and its Agents) designated by the insurer whose policy
covers such occurrence or by counsel designated by Tenant and approved by
Landlord and its Agents. Tenant's obligations pursuant to this Section 15 shall
survive the expiration or termination of this lease.

16.  Waiver of Claims.  Landlord and Tenant each hereby waives all claims for
     ----------------
recovery against the other for any loss or damage which may be inflicted upon
the property of such party even if such loss or damage shall be brought about by
the fault or negligence of the other party or its Agents; provided, however,
that such waiver by Landlord shall not be effective with respect to any
liability of Tenant described in Sections 4(c) and 7(d)(iv).

17.  Quiet Enjoyment.  Landlord covenants that Tenant, upon performing all of
     ---------------
its covenants, agreements and conditions of this lease, shall have quiet and
peaceful possession of the Premises as against anyone claiming by or through
Landlord, subject, however, to the exceptions, reservations and conditions of
this lease.

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

          (a)  Limitation. Tenant shall not transfer this lease, voluntarily or
by operation of law, without the prior written consent of Landlord which shall
not be withheld unreasonably. However, Landlords consent shall not be required
in the event of any transfer by Tenant to an affiliate of Tenant which is at
least as creditworthy as Tenant as of the date of this lease and provided Tenant
delivers to Landlord the instrument described in Section (c)(iii) below,
together with a certification of such creditworthiness by Tenant and such
affiliate. Any transfer not in conformity with this Section 18 shall be void at
the option of Landlord, and Landlord may exercise any or all of its rights under
Section 23. A consent to one transfer shall not be deemed to be a consent to any
subsequent transfer. "Transfer" shall include any sublease, assignment, license
or concession agreement, change in ownership or control of Tenant, mortgage or
hypothecation of this lease or Tenant's interest therein or in all or a portion
of the Premises.

          (b)  Offer to Landlord. Tenant acknowledges that the terms of this
lease, including the Minimum Annual Rent, have been based on the understanding
that Tenant physically shall occupy the Premises for the entire Term. Therefore,
upon Tenant's request to transfer all or a portion of the Premises, at the
option of Landlord, Tenant and Landlord shall execute an amendment to this lease
removing such space from the Premises, Tenant shall be relieved of any liability
with respect to such space and Landlord shall have the right to lease such space
to any party, including Tenants proposed transferee.

          (c)  Conditions. Notwithstanding the above, the following shall apply
to any transfer, with or without Landlord's consent:

                   (i)   As of the date of any transfer, Tenant shall not be in
default under this lease nor shall any act or omission have occurred which would
constitute a default with the giving of notice and/or the passage of time.

                   (ii)  No transfer shall relieve Tenant of its obligation to
pay the Rent and to perform all its other obligations hereunder. The acceptance
of Rent by Landlord from any person shall not be deemed to be a waiver by
Landlord of any provision of this lease or to be a consent to any transfer.

                   (iii) Each transfer shall be by a written instrument in form
and substance satisfactory to Landlord which shall (A) include an assumption of
liability by any transferee of all Tenant's obligations and the transferee's
ratification of and agreement to be bound by all the provisions of this lease,
(B) afford Landlord the right of direct action against the transferee pursuant
to the same remedies as are available to Landlord against Tenant and (C) be
executed by Tenant and the transferee.

                   (iv)  Tenant shall pay, within 10 days of receipt of an
invoice which shall be no less than $250, Landlord's reasonable attorneys' fees
and costs in connection with the review, processing and documentation of any
transfer for which Landlord's consent is requested.

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

primary encumbrance now or hereafter affecting the Premises. Although the
subordination is self-operative, within 10 days after written request, Tenant
shall execute and deliver any further instruments confirming such subordination
of this lease and any further instruments of attornment that may be desired by
any such mortgagee or Landlord. However, any mortgagee may at any time
subordinate its mortgage to this lease, without Tenant's consent, by giving
written notice to Tenant, and thereupon this lease shall be deemed prior to such
mortgage without regard to their respective dates of execution and delivery;
provided, however, that such subordination shall not affect any mortgagee's
right to condemnation awards, casualty insurance proceeds, intervening liens or
any right which shall arise between the recording of such mortgage and the
execution of this lease.

          (b)  It is understood and agreed that any mortgagee shall not be
liable to Tenant for any funds paid by Tenant to Landlord unless such funds
actually have been transferred to such mortgagee by Landlord.

          (c)  Notwithstanding the provisions of Sections 12 and 13 above,
Landlord's obligation to restore the Premises after a casualty or condemnation
shall be subject to the consent and prior rights of Landlord's first mortgagee.

20.  Recording; Tenant's Certificate.  Tenant shall not record this lease or a
     -------------------------------
memorandum thereof without Landlords prior written consent.  Within 10 days
after Landlords written request from time to time:

          (a)  Tenant shall execute, acknowledge and deliver to Landlord a
written statement certifying the Commencement Date and Expiration Date of this
lease, that this lease is in full force and effect and has not been modified and
otherwise as set forth in the

                                       7
<PAGE>

form of estoppel certificate attached as Exhibit "D" or with such modifications
as may be necessary to reflect accurately the stated facts and/or such other
certifications as may be requested by a mortgagee or purchaser.  Tenant
understands that its failure to execute such documents may cause Landlord
serious financial damage by causing the failure of a financing or sale
transaction.

          (b)  Tenant shall furnish to Landlord, Landlords mortgagee,
prospective mortgagee or purchaser reasonably requested financial information.

21.  Surrender; Abandoned Property.
     -----------------------------

          (a)  Subject to the terms of Sections 9(b), 12(a) and 13(b), at the
expiration or termination of this lease, Tenant promptly shall yield up in the
same condition, order and repair in which they are required to be kept
throughout the Term, the Premises and all improvements thereto, and all fixtures
and equipment servicing the Building, ordinary wear and tear excepted.

          (b)  Upon or prior to the expiration or termination of this lease,
Tenant shall remove any personal property from the Property. Any personal
property remaining thereafter shall be deemed conclusively to have been
abandoned, and Landlord, at Tenant's expense, may remove, store, sell or
otherwise dispose of such property in such manner as Landlord may see fit and/or
Landlord may retain such property as its property. If any part thereof shall be
sold, then Landlord may receive and retain the proceeds of such sale and apply
the same, at its option, against the expenses of the sale, the cost of moving
and storage and any Rent due under this lease.

          (c)  If Tenant, or any person claiming through Tenant, shall continue
to occupy the Premises after the expiration or termination of this lease or any
renewal thereof, such occupancy shall be deemed to be under a month-to-month
tenancy under the same terms and conditions set forth in this lease, except that
the monthly installment of the Minimum Annual Rent during such continued
occupancy shall be double the amount applicable to the last month of the Term.
Anything to the contrary notwithstanding, any holding over by Tenant without
Landlords prior written consent shall constitute a do-fault hereunder and shall
be subject to all the remedies available to Landlord.

22.  Curing Tenant's Defaults.  If Tenant shall be in default in the performance
     ------------------------
of any of its obligations hereunder, Landlord, without any obligation to do so,
in addition to any other rights it may have in law or equity, may elect to cure
such default on behalf of Tenant after written notice (except in the case of
emergency) to Tenant.  Tenant shall reimburse Landlord upon demand for any sums
paid or costs incurred by Landlord in curing such default, including interest
thereon from the respective dates of Landlord's incurring such costs, which sums
and costs together with interest shall be deemed additional rent.

23.  Defaults -Remedies.
     ------------------

          (a)  Defaults.  It shall bean event of default:

                  (i)    If Tenant does not pay in full when due any and all
Rent;

                  (ii)   If Tenant fails to observe and perform or otherwise
breaches any other provision of this lease;

                  (iii)  If Tenant abandons the Premises, which shall be
conclusively presumed if the Premises remain unoccupied for more than 10
consecutive days, or removes or attempts to remove Tenant' s goods or property
other than in the ordinary course of business; or

                  (iv)   If Tenant becomes insolvent or bankrupt in any sense or
makes a general assignment for the benefit of creditors or offers a settlement
to Creditors, or if a petition in bankruptcy or for reorganization or for an
arrangement with creditors under any federal or state law is filed by or against
Tenant, or a bill in equity or other proceeding for the appointment of a
receiver for any of Tenant's assets is commenced, or if any of the real or
personal property of Tenant shall be levied upon; provided, however, that any
proceeding brought by anyone other than Landlord or Tenant under any bankruptcy,
insolvency, receivership or similar law shall not constitute a default until
such proceeding has continued unstayed for more than 60 consecutive days.

          (b)  Remedies.  Then, and in any such event, Landlord shall have the
following rights:

                  (i)    To charge a late payment fee equal to the greater of
$100 or 5% of any amount owed to Landlord pursuant to this lease which is not
paid within 5 days after the due date.

                  (ii)   To enter and repossess the Premises, by breaking open
locked doors if necessary, and remove all persons and all or any property
therefrom, by action at law or otherwise, without being liable for prosecution
or damages therefor, and Landlord may,

                                       8
<PAGE>

at Landlords option, make alterations and repairs in order to relet the Premises
and relet all or any part(s) of the Premises for Tenant's account.  Tenant
agrees to pay to Landlord on demand any deficiency that may arise by reason of
such reletting.  In the event of reletting without termination of this lease,
Landlord may at any time thereafter elect to terminate this lease for such
previous breach.

               (iii)  To accelerate the whole or any part of the Rent for the
balance of the Term, and declare the same to be immediately due and payable.

               (iv)   To terminate this lease and the Term without any right on
the part of Tenant to save the forfeiture by payment of any sum due or by other
performance of any condition, term or covenant broken.

          (c)  Grace Period. Notwithstanding anything hereinabove stated,
neither party will exercise any available right because of any default of the
other, except those remedies contained in subsection (b)(i) of this Section,
unless such party shall have first given 10 days written notice thereof to the
defaulting party, and the defaulting party shall have failed to cure the default
within such period; provided, however, that:

               (i)    No such notice shall be required if Tenant fails to comply
with the provisions of Sections 10 or 20(a), in the case of emergency as set
forth in Section 22 or in the event of any default enumerated in subsections
(a)(iii) and (iv) of this Section.

               (ii)   Landlord shall not be required to give such 10 days notice
more than 2 times during any 12 month period.

               (iii)  If the default consists of something other than the
failure to pay money which cannot reasonably be cured within 10 days, neither
party will exercise any right if the defaulting party begins to cure the default
within the 10 days and continues actively and diligently in good faith to
completely cure said default.

               (iv)   Tenant agrees that any notice given by Landlord pursuant
to this Section which is served in compliance with Section 27 shall be adequate
notice for the purpose of Landlords exercise of any available remedies.

          (d)  Non-Waiver; Non-Exclusive. No waiver by Landlord of any breach by
Tenant shall be a waiver of any subsequent breach, nor shall any forbearance by
Landlord to seek a remedy for any breach by Tenant be a waiver by Landlord of
any rights and remedies with respect to such or any subsequent breach. Efforts
by Landlord to mitigate the damages caused by Tenant's default shall not
constitute a waiver of Landlord's right to recover damages hereunder. No right
or remedy herein conferred upon or reserved to Landlord is intended to be
exclusive of any other right or remedy provided herein or by law, but each shall
be cumulative and in addition to every other right or remedy given herein or now
or hereafter existing at law or in equity. No payment by Tenant or receipt or
acceptance by Landlord of a lesser amount than the total amount due Landlord
under this lease shall be deemed to be other than on account, nor shall any
endorsement or statement on any check or payment be deemed an accord and
satisfaction, and Landlord may accept such check or payment without prejudice to
Landlord's right to recover the balance of Rent due, or Landlord's right to
pursue any other available remedy.

          (e)  Costs and Attorneys' Fees.  If either party commences an action
against the other party arising out of or in connection with this lease, the
prevailing party shall be entitled to have and recover from the losing party
attorneys' fees, costs of suit, investigation expenses and discovery costs,
including costs of appeal.

obligations and liabilities and each of which shall have the same rights,
privileges and powers as it would have possessed had it originally signed this
lease as Tenant. Each and every of the persons named above as Tenant shall be
bound jointly and severally by the terms, covenants and agreements contained
herein. However, no such rights, privileges or powers shall inure to the benefit
of any assignee of Tenant immediate or remote, unless Tenant has complied with
the terms of Section 18 and the assignment to such assignee is permitted or has
been approved in writing by Landlord. Any notice required or permitted by the
terms of this lease may be given by or to any one of the persons named above as
Tenant, and shall have the same force and effect as if given by or to all
thereof.

          (b)  If Tenant is a corporation, partnership or any other form of
business association or entity, Tenant is duly formed and in good standing, and
has full corporate or partnership power and authority, as the case may be, to

case may be, necessary to carry out the transaction contemplated herein, so that
when executed, this lease constitutes a valid and binding obligation enforceable
in accordance with its terms. Tenant shall provide

ceases to hold title to the Premises except for obligations already accrued
(and, as to any unapplied portion of Tenant's Security Deposit, Landlord shall
be relieved of all liability therefor upon transfer of such portion to its
successor in interest) and Tenant shall look solely to Landlord's successor in
interest for the performance of the covenants and obligations of the Landlord
hereunder which thereafter shall accrue.  Neither Landlord nor any principal of
Landlord nor any owner of the Property, whether disclosed or undisclosed, shall
have any personal liability with respect to any of the provisions of this lease
or the Premises, and if Landlord is in breach or default with respect to
Landlord's obligations under this lease or otherwise, Tenant shall look solely
to the equity of Landlord in the Property for the satisfaction of Tenant's
claims.  Notwithstanding the foregoing, no mortgagee or ground lessor succeeding
to the interest of Landlord hereunder (either in terms of ownership or
possessory rights) shall be (a) liable for any previous act or omission of a
prior landlord, (b) subject to any rental offsets or defenses against a prior
landlord or (c) bound by any amendment of this lease made without its written
consent, or by payment by Tenant of Minimum Annual Rent in advance in excess of
one monthly installment.

Property in

                                       10

other party designated by Landlord. Each notice or other communication shall be
deemed given if sent by prepaid overnight delivery service or by certified mail,

actual receipt by the intended recipient or on the business day delivery is
refused.  The giving of notice by Landlords attorneys, representatives and
agents under this Section shall be deemed to be the acts of Landlord; however,
the foregoing provisions governing the date on which a notice is deemed to have

and not its counsel or other recipient to which a copy of the notice may be
sent, is deemed to have received the notice.

default under this lease.  If Landlord uses all or any portion of the Security
Deposit as herein provided, within 10 days after written demand therefor, Tenant
shall pay Landlord cash in amount equal to that portion of the Security Deposit

Landlord in any measures implemented by Landlord to control abuse of the parking

maintenance, operation and cleanliness of the Property.  Notice of any action by
Landlord referred to in this paragraph, given to Tenant, shall have the same
force and effect as if originally made a part of the foregoing lease.  New rules
or regulations will not, however, be unreasonably inconsistent with the proper
and rightful enjoyment of the Premises by Tenant under the lease.

     18.  These Building Rules are not intended to give Tenant any rights or
claims in the event that Landlord does not enforce any of them against any other
tenants or if Landlord does not have the right to enforce them against any other
tenants and such non-enforcement will not constitute a waiver as to Tenant.
