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 1(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 true
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 mixtures, 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 Landlord's 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 l(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 Best'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 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.


                                        5

     (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
Landlord's 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 termparary 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, Landlord's 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 Tenant's 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.

19. SUBORDINATION; MORTGAGEE'S RIGHTS.

     (A) This lease shall be subordinate to any first mortgage or other 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 Landlord's prior written consent. Within 10 days
after Landlord's 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 fact 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, Landlord's 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
Landlord's prior written consent shall constitute a default 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 be an 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 landlord's 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 Landlord's 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.

24. REPRESENTATIONS OF TENANT. Tenant represents to Landlord and agrees that:

     (A) The word "TENANT" as used herein includes the Tenant named above as
well as its successors and assigns, each of which shall be under the same
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 enter into
this lease and has taken all corporate or partnership action, as the 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


                                        9

<PAGE>

Landlord with corporate resolutions or other proof in a form acceptable to
Landlord, authorizing the execution of this lease at the time of such execution.

25. LIABILITY OF LANDLORD. The word "LANDLORD" as used herein includes the
Landlord named above as well as its successors and assigns, each of which shall
have the same rights, remedies, powers, authorities and privileges as it would
have had it originally signed this lease as Landlord. Any such person or entity,
whether or not named herein, shall have no liability hereunder after it 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.

26. INTERPRETATION; DEFINITIONS.

     (A) CAPTIONS. The captions in this lease are for convenience only and are
not a part of this lease and do not in any way define, limit, describe or
amplify the terms and provisions of this lease or the scope or intent thereof.

     (B) ENTIRE AGREEMENT. This lease represents the entire agreement between
the parties hereto and there are no collateral or oral agreements or
understandings between Landlord and Tenant with respect to the Premises or the
Property. No rights, easements or licenses are acquired in the Property or any
land adjacent to the Property by Tenant by implication or otherwise except as
expressly set forth in the provisions of this lease. This lease shall not be
modified in any manner except by an instrument in writing executed by the
parties. The masculine (or neuter) pronoun and the singular number shall include
the masculine, feminine and neuter genders and the singular and plural number.
The word "INCLUDING" followed by any specific item(s) is deemed to refer to
examples rather than to be words of limitation. Both parties having participated
fully and equally in the negotiation and preparation of this lease, this lease
shall not be more strictly construed, nor any ambiguities in this lease
resolved, against either Landlord or Tenant.

     (C) COVENANTS. Each covenant, agreement, obligation, term, condition or
other provision herein contained shall be deemed and construed as a separate and
independent covenant of the party bound by, undertaking or making the same, not
dependent on any other provision of this lease unless otherwise expressly
provided. All of the terms and conditions set forth in this lease shall apply
throughout the Term unless otherwise expressly set forth herein.

     (D) INTEREST. Wherever interest is required to be paid hereunder, such
interest shall be at the highest rate permitted under law but not in excess of
15% per annum.

     (E) SEVERABILITY; GOVERNING LAW. If any provisions of this lease shall be
declared unenforceable in any respect, such unenforceability shall not affect
any other provision of this lease, and each such provision shall be deemed to be
modified, if possible, in such a manner as to render it enforceable and to
preserve to the extent possible the intent of the parties as set forth herein.
This lease shall be construed and enforced in accordance with the laws of the
state in which the Property is located.

     (F) "MORTGAGE" AND "MORTGAGEE." The word "MORTGAGE" as used herein includes
any lien or encumbrance on the Premises or the Property or on any part of or
interest in or appurtenance to any of the foregoing, including without
limitation any ground rent or ground lease if Landlord's interest is or becomes
a leasehold estate. The word "MORTGAGEE" as used herein includes the holder of
any mortgage, including any ground lessor if Landlord's interest is or becomes a
leasehold estate. Wherever any right is given to a mortgagee, that right may be
exercised on behalf of such mortgagee by any representative or servicing agent
of such mortgagee.

     (G) "PERSON." The word "person" is used herein to include a natural person,
a partnership, a corporation, an association and any other form of business
association or entity.

     (H) PROPORTIONATE SHARE. At any time or times, upon request of Landlord or
of any tenant of the Building, the method for allocating Tenant's Proportionate
Share of any Impositions, cost, charge, rent, expense or payment then or
thereafter payable shall be redetermined by an independent qualified expert. The
cost of such redetermination shall be borne by the tenants of the Building in


                                       10

<PAGE>
the same proportion as that determination such expert for reallocation of said
relevant sum; except that if such redetermination is requested by a tenant, the
cost thereof shall be borne entirely by such tenant if the proportionate share
of said relevant sum allocable to such tenant as the result of such
redetermination shall not vary by at least 5% from the amount which would have
been allocable to such tenant in accordance with the percentage based on square
foot area.

27. NOTICES. Any notice or other communication under this lease shall be in
writing and addressed to Landlord or Tenant at their respective addresses
specified at the beginning of this lease, except that after the Commencement
Date Tenant's address shall be at the Premises, (or to such other address as
either may designate by notice to the other) with a copy to any mortgagee or
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,
return receipt requested, postage prepaid or in any other manner, with delivery
in any case evidenced by a receipt, and shall be deemed received on the day of
actual receipt by the intended recipient or on the business day delivery is
refused. The giving of notice by Landlord's 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
been received shall mean and refer to the date on which a party to this lease,
and not its counsel or other recipient to which a copy of the notice may be
sent, is deemed to have received the notice.

28. SECURITY DEPOSIT. At the time of signing this lease, Tenant shall, deposit
with Landlord the Security Deposit to be retained by Landlord as cash security
for the faithful performance and observance by Tenant of the provisions of this
lease. Tenant shall not be entitled to any interest whatever on the Security
Deposit. Landlord shall have the right to commingle the Security Deposit with
its other funds. Landlord may use the whole or any part of the Security Deposit
for the payment of any amount as to which Tenant is in default hereunder or to
compensate Landlord for any loss or damage it may suffer by reason of Tenant's
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
used by Landlord. If Tenant shall comply fully and faithfully with all of the
provisions of this lease, the Security Deposit shall be returned to Tenant after
the Expiration Date and surrender of the Premises to Landlord.

     IN WITNESS WHEREOF, and in consideration of the mutual entry into this
lease and for other good and valuable consideration, and intending to be legally
bound, Landlord and Tenant have executed this lease.

(In the event of any conflict between the provisions of this Rider and the Lease
Agreement to which it is attached, the provisions of this Rider will govern,
control and prevail. All capitalized terms used but not defined in this Rider
shall have the meanings given to them in the Lease Agreement.)

29. Radon Gas. Radon is a naturally occurring radioactive gas that, when it has
accumulated in a building in sufficient quantities, may present health risks to
persons who are exposed to it over time. Levels of radon that exceed federal and
state guidelines have been found in buildings in Florida. Additional information
regarding radon and radon testing may be obtained from your county public health
unit.

30. Completion by Tenant.

     (a) At Tenant's option, the Premises shall be completed by Tenant and its
contractor(s), at Tenant's sole expense, in accordance with the plans attached
hereto as Exhibit "E" (the "Plans") and the specifications attached hereto as
Exhibit "F" (the "Specifications"). In addition to the improvements shown on the
Plans and Specifications, Tenant may, at its sole cost and expense, make the
following improvements to the exterior of or outside the Premises (the
"Additional Improvements"): (i) remove two (2) 36" wide door units to the
Premises and replace same with two (2) 72" wide door units to the Premises
(provided, however, upon the expiration or earlier termination of this lease,
Tenant shall restore the 36" wide door units and repair any damage caused by
such installation and removal); (ii) widen existing ramps to conform to new door
widths; (iii) remove several short bushes impeding access to the new doors; and
(iv) move one (1) handicapped parking space approximately 20 feet north.
Landlord hereby consents to the alterations Tenant intends to make to the
Premises in accordance with the Plans and Specifications and the Additional
Improvements, provided that Tenant complies with Sections 9 and 10 of this lease
and the following conditions:

          (i) At least ten (10) days prior to commencement of construction,
Tenant shall deliver to Landlord a certificate of insurance for each of Tenant's
contractors evidencing adequate insurance coverage naming Landlord and
Landlord's agent as additional insureds.

          (ii) In addition to the right of Landlord and its Agents to inspect
the Premises set forth in Section 11 of this lease, Landlord and its Agents
shall have the right to conduct a walk-through inspection of the Premises as
completed by Tenant.

          (iii) The warranties from Tenant's contractor(s) shall be for the
benefit of Landlord as well as Tenant and Tenant shall deliver such warranties
to Landlord upon receipt.

          (iv) All construction shall be done in a good and workmanlike manner
and shall comply at the time of completion with all Laws and Requirements.
Tenant shall deliver to Landlord copies of all certificates of occupancy,
permits and licenses required to be issued by any authority in connection with
Tenant's construction.

     (b) Landlord agrees that Tenant shall be entitled to a tenant improvement
allowance (the "Allowance") in the amount of $173,619 which may be used by
Tenant in connection with the initial buildout of the Premises by Tenant as set
forth in subsection (a) above and any further alterations made by Tenant during
the Term of the lease pursuant to Section 9 of the lease, including without
limitation, improvements to the Premises, computer/telephone infrastructure,
work station installation and the installation of any wiring, cabling, signage
and/or security systems (the "Tenant Improvements"). Provided Tenant is not then
in default under the lease, within 60 days after (i) Landlord's receipt of
invoice therefor and evidence of Tenant's payment thereof, and (ii) inspection
of the premises by Landlord to confirm the completion of the work covered by
such invoice. Landlord shall pay Tenant the amount of such invoice, the total of
all advances by Landlord hereunder not to exceed $173,619. With respect to
requests by Tenant for advances of the Allowance in excess of $86,809.50 in the
aggregate on account of payment for Tenant Improvements, Tenant shall also be
required, as a condition precedent to Landlord's obligation to make any such
advance, to deliver to Landlord a letter of credit as required in Section 51 (or
endorsement thereto) increasing Tenant's Security Deposit hereunder by the
amount of such advance.

     (c) In the event the Allowance is not fully advanced by Landlord and
provided Tenant is not then in default hereunder, the unadvanced balance of the
Allowance as of November 1, 2004, but not more than $86,809.50 (the "Maximum
Rent Credit"), shall, at Tenant's option, upon prior written notice to Landlord
given on or before October 1, 2004, be credited against Minimum Annual Rent
first coming due under the Lease. It is expressly agreed and understood that the
Allowance will not be credited against Annual Operating Expenses.

     (d) In the event the Allowance is not fully advanced by Landlord as of the
date which is six (6) months prior to the Expiration Date and provided Tenant is
not then in default hereunder, the remaining balance of the Maximum Rent Credit
not advanced pursuant to subsection (c) above, if any (but not in excess of the
unadvanced balance of the Allowance), shall be credited against Minimum Annual
Rent next coming due under the Lease. It is expressly agreed that the Allowance
will not be credited against Annual Operating Expenses.

     (e) At Tenant's option, Landlord will apply the Allowance to improvements
performed by Tenant to space leased by Tenant from Landlord at 13650 N.W. 8th
Street, Sunrise, Florida; however, any credit against Minimum Annual Rent to
which Tenant may be entitled hereunder shall only be made against Minimum Annual
Rent due and payable under this lease.

31. Early Occupancy. Tenant and its authorized agents, employees and contractors
shall at all reasonable times on or after the date of execution of this lease
and prior to the Commencement Date have the right, at Tenant's own risk, expense
and responsibility, to occupy the Premises. If Tenant occupies the Premises
prior to the Commencement Date, Tenant shall abide by the terms and conditions
of this lease including payment of all utilities which are separately metered to
the Premises, Premises Direct Operating Expenses and any other sums payable by
Tenant to Landlord pursuant to this lease, as if the term of this lease had
already commenced, except that


                                       R-2

Tenant shall have no obligation to pay the Minimum Annual Rent or Annual
Operating Expenses or any portion thereof until the Commencement Date.

32. Option to Extend Term. Provided that Landlord has not given Tenant notice of
default more than two (2) times in the immediately preceding twelve (12) months,
that there then exists no event of default by Tenant under this lease nor any
event that with the giving of notice and/or the passage of time would constitute
a default, and that Tenant or a person or entity to whom Tenant has the right to
assign this lease or sublet the Premises without Landlord's prior written
consent pursuant to Section 18(a) of this lease are the sole occupants of the
Premises, Tenant shall have the right and option to extend the Term for two (2)
additional periods of thirty-six (36) months each, exercisable by giving
Landlord prior written notice, at least nine (9) months in advance of the
Expiration Date or the first extended Expiration Date, as the case may be, of
Tenant's election to extend the Term; it being agreed that time is of the
essence and that this option is personal to Tenant and to any person or entity
to whom Tenant has the right to assign this lease or sublet the Premises without
Landlord's prior written consent pursuant to Section 18(a) of this lease and is
non-transferable to any other assignee or sublessee (regardless of whether any
such assignment or sublease was made with or without Landlord's consent) or
other party. Such extension shall be under the same terms and conditions as
provided in this lease except as follows:

     (a) the first additional period shall begin on the initial Expiration Date
and thereafter the Expiration Date shall be deemed to be the date which is
thirty-six (36) months after the initial Expiration Date;

     (b) the second additional period shall begin on the first extended
Expiration Date and thereafter the Expiration Date shall be deemed to be the
date which is seventy-two (72) months after the initial Expiration Date;

     (c) there shall be no further options to extend;

     (d) The minimum annual rent for the first year of each additional term
shall be equal to the greater of (i) the minimum annual rent then being paid by
Tenant hereunder, or (ii) 95% of the fair market rental value of the Premises,
determined pursuant to subsection (e) hereof. The minimum annual rent for each
subsequent year of each additional term shall increase by $0.50 per rentable
square foot over the minimum annual rent payable in the immediately preceding
year. For purposes hereof, "fair market rental value of the Premises" shall be
the then prevailing fair market rental value for tenants leasing space of
comparable size in comparable buildings in the Sunrise, Florida area for the
same period of time (taking into account such leasing and economic terms as are
then obtained in the market).


                                       R-3

<PAGE>

     (e) For purposes of this Section 32, if Landlord and Tenant cannot agree as
to the fair market rental value within thirty (30) days after receipt of
Tenant's notice to Landlord under subsection 32(a), the fair market rental value
shall be determined by appraisal. Within ten (10) days after the expiration of
such thirty (30) day period, Landlord and Tenant shall give written notice to
the other setting forth the name and address of an appraiser designated by the
party giving notice. All appraisers selected shall be members of the American
Institution of Real Estate Appraisers and shall have had at least ten (10) years
continuous experience in the business of appraising office buildings in the
greater Sunrise, Florida area. If either party shall fail to give notice of such
designation within the time period provided, then the party who has designated
its appraiser (the "Designating Party") shall notify the other party (the
"Non-Designating Party") in writing that the Non-Designating Party has an
additional ten (10) days to give notice of its designation, otherwise the
appraiser, if any, designated by the Designating Party shall conclusively
determine the fair market rental value. If two appraisers have been designated,
such appraisers shall attempt to agree upon the fair market rental value. If the
two appraisers do not agree on the fair market rental value within twenty (20)
days of their designation, the two appraisers shall designate a third appraiser.
If the two appraisers shall fail to agree upon the identity of a third appraiser
within five (5) business days following the end of such twenty (20) day period,
then either Landlord or Tenant may apply to the American Arbitration
Association, or any successor thereto having jurisdiction, for the settlement of
the dispute as to the designation of the third appraiser and the American
Arbitration Association shall designate a third appraiser in accordance with the
Real Estate Valuation Arbitration Rules of the American Arbitration Association.
The three appraisers shall conduct such hearings as they may deem appropriate,
shall make their determination of fair market rental value in writing and shall
give notice to Landlord and Tenant of such determination within twenty (20) days
after the appointment of the third appraiser. If the three appraisers cannot
agree upon the fair market rental value, each appraiser shall submit in writing
to Landlord and Tenant the fair market rental value as determined by such
appraiser. The fair market rental value for the purposes of this paragraph shall
be equal to the arithmetic average of the two closest fair market rental values
submitted by the appraisers. Each party shall pay its own fees and expenses in
connection with any appraiser selected by such party under this paragraph, and
the parties shall share equally all other expenses and fees of the arbitration,
including the fees and expenses charged by the third appraiser. The fair market
rental value as determined in accordance with the provisions of this Section
shall be final and binding upon Landlord and Tenant.

33. Waiver of Jury Trial. Landlord and Tenant by this subparagraph waive trial
by jury in any action, proceeding, or counterclaim brought by either of the
parties to this lease against the other on any matters whatsoever arising out of
or in any way connected with this lease, the relationship of Landlord and
Tenant, Tenant's use or occupancy of the Premises, or any other claims
(including without limitation claims for personal injury or property damage),
and any emergency statutory or any other statutory remedy.

34.  Brokers: Recognition and Indemnity.

     (a) Tenant and Landlord represent and warrant to each other that U.S.
Realty Advisors, Inc. is the only broker or finder that either has had any
dealings, negotiations or consultations with relating to the Premises or this
transaction and that no other broker or finder called the Premises to Tenant's
attention for lease or took any part in any dealings, negotiations or
consultations relating to the Premises or this lease. Such named broker is
entitled to a commission from Landlord pursuant to a separate agreement between
Landlord and such broker.

     (b) Tenant agrees to be responsible for, indemnify, defend and hold
harmless Landlord from and against all costs, fees (including, without
limitation, attorney's fees), expenses, liabilities and claims incurred or
suffered by Landlord arising from any breach by Tenant of Tenant's foregoing
representation and warranty. Landlord agrees to be responsible for, indemnify,
defend and hold harmless Tenant from and against all costs, fees (including,
without limitation, attorney's fees), expenses, liabilities and claims incurred
or suffered by Tenant arising from any breach by Landlord of Landlord's
foregoing representation and warranty.

35. Consents. Whenever the consent of a party hereto is required hereunder, such
consent shall not be unreasonably withheld, conditioned or delayed.

36. Parking. The parking lots appurtenant to the Property contain 4.5 parking
spaces per 1000 rentable square feet in the Building. So long as Tenant's leases
in the Building and the Adjacent Building remain in full force and effect,
Tenant and its Agents shall have the right to the exclusive use, without charge,
of those parking spaces shown as "Tenant's Exclusive Parking" on Exhibit "A"
attached hereto. At Tenant's option, Landlord shall designate some or all of
such exclusive parking spaces as reserved spaces by appropriate signs or
painting, but shall have no duty to enforce such exclusive or reserved parking.
To the extent additional spaces in the parking lots are available, Tenant and
its Agents shall have the right to use same, without charge on a non-exclusive
basis, provided that such use does not deprive other tenants in the Building
from using their respective Proportionate Shares of the spaces in the parking
areas in violation of their respective leases.

37. Additional Contiguous Space. If and when any other space in the Building or
in the adjacent building at 13650 N.W. 8th Street (the "Adjacent Building")
(individually, the "Additional Space") first becomes available for rental during
the term of this lease and provided that Landlord has not given Tenant notice of
default more than two (2) times during the immediately preceding twelve (12)
months, that there then exists no event of default by Tenant under this lease
nor any event that with the giving of notice and/or the passage of time would
constitute a default, and that Tenant is the sole occupant of the Premises,
Tenant shall have the right of first offer to lease all of each Additional
Space, subject to the following:

     (a) Landlord shall notify Tenant when each Additional Space first becomes
available for rental by any party other than the tenant then in occupancy of
such Additional Space and Tenant shall have five (5) business days following
receipt of such notice within which to notify Landlord in writing that Tenant is
interested in negotiating terms for leasing such Additional


                                       R-5

<PAGE>

Space and to have its offer considered by Landlord prior to the leasing by
Landlord of such Additional Space to a third party. If Tenant notifies Landlord
within such time period that Tenant is so interested, then Landlord and Tenant
shall have ten (10) business days following Landlord's receipt of such notice
from Tenant within which to negotiate mutually satisfactory terms for the
leasing of such Additional Space by Tenant and to execute an amendment to this
lease incorporating such terms or a new lease for such Additional Space.

     (b) If Tenant does not notify Landlord within such five (5) business days
of its interest in leasing such Additional Space or if Tenant does not execute
such amendment or lease within such ten (10) business days, if applicable, then
this right of first offer to lease such Additional Space will lapse and be of no
further force or effect and Landlord shall have the right to lease all or part
of such Additional Space to any other party at any time on any terms and
conditions acceptable to Landlord.

     (c) This right of first offer to lease each Additional Space is a one-time
right if and when each Additional Space first becomes available, is personal to
Tenant and is non-transferable to any assignee or sublessee (regardless of
whether any such assignment or sublease was made with or without Landlord's
consent) or other party, and with respect to the Adjacent Building, is only
effective so long as both the Building and the Adjacent Building are owned by
the same party.

furniture, fixtures, equipment, chattels, inventory, and other tangible personal

which (i) provides financing to Tenant secured by any of such items, or (ii)
provides such items or the funds to purchase or lease the same, or (b) Tenant's
general business creditors (if granted in the normal course of business).

is more than 6%, the excess may be billed to Tenant in any future year in which
the increase in controllable operating expenses on an annualized basis is less
than 6% as long as in any year controllable operating expenses are not in excess

          (E) access to the Premises 24 hours per day, 365 (or 366, if
applicable) days per year, except during necessary repairs or emergencies."

     (f) Add a new Section (g) as follows:

          "(g) Landlord shall make all necessary repairs to the Premises,
including, without limitation, maintenance, repair and replacement of the HVAC
systems appurtenant to the Premises, and shall provide Tenant with trash removal
and janitorial services pursuant to a cleaning schedule attached hereto as
Exhibit "G"; provided that Landlord shall have no responsibility to make any
repair until Landlord receives written notice of the need for such repair. The
services to be provided by Landlord pursuant to this Section 7(g) (the 'Premises
Direct Services') include (1) janitorial services per Exhibit 'G', emergency
day-time clean-up needs, janitorial supplies, semi-annual interior window
cleaning, exterminating, trash removal and recycling, (2) Premises maintenance
and repair, including supplies and parts (e.g., lighting, ceiling tiles,
plumbing, mechanical, etc.), 24-hour on-call maintenance technicians and
property management, and (3) HVAC maintenance, repair and replacement, including
semi-annual indoor air quality testing, preventive maintenance and on-call
repairs and maintenance, including parts and labor. The costs for Premises
Direct Services (the 'Premises Direct Operating Expenses') shall be provided at
the sole expense of Tenant. Tenant shall pay to Landlord the Premises Direct
Operating Expenses in equal monthly installments in the amount set forth in
Section l(d)(iii) (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. Landlord
shall apply such payments to the Premises Direct Operating Expenses owed to
Landlord by Tenant pursuant to this Section 7(g). The amount of the Premises
Direct Operating Expenses set forth in Subsection 1(d)(iii) represents the
estimated Premises Direct 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 Premises Direct 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 Premises Direct Operating 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 Premises Direct Operating Expenses pursuant to this
Section 7(g) shall survive the expiration or termination of this lease.

               Premises Direct Operating Expenses for calendar year 2004 on an
annualized basis shall not exceed $0.91 per rentable square foot of the
Premises. Commencing with calendar year 2005, annual increases in Premises
Direct Operating Expenses on an annualized basis shall not exceed 6% more than
such Premises Direct Operating Expenses for the prior calendar year on an
annualized basis. In the event an increase in Premises Direct Operating Expenses
on an annualized basis in any year is more than 6%, the excess may be billed to
Tenant


                                      R-11

<PAGE>

in any future year in which the increase in Premises Direct Operating Expenses
on an annualized basis is less than 6% as long as in any year Premises Direct
Operating Expenses are not in excess of 6% more than the Premises Direct
Operating Expenses in the immediately preceding year on an annualized basis."

               Notwithstanding anything to the contrary herein contained, Tenant
shall have the right, at any time during the Term, upon thirty (30) days prior
written notice to Landlord, to provide its own janitorial services with respect
to the Premises. In such event janitorial services shall no longer be included
in Premises Direct Services and appropriate adjustments shall be made to
Premises Direct Operating Expenses for the current calendar year and, for
purposes only of determining the maximum increase in Premises Direct Operating
Expenses for the current calendar year, appropriate adjustments shall be made to
Premises Direct Operating Expenses for the prior calendar year to reflect
janitorial expenses for the same length of time Landlord provided same in the
current calendar year.

43. Additional Provisions Relating to Signs. Section 8 of the lease is amended
as follows:

governmental and owner association approvals therefor, Tenant at its sole
expense shall be permitted to install and maintain identification signs in
existing colors specifying Tenant's name and logo (i) on each of the three (3)
sides of the exterior of the Building abutting the Premises, (ii) on the wall
space immediately adjacent to its main entrance doors to the Premises, and (iii)
on an additional monument sign at the entrance to the Property. Landlord shall
cooperate with Tenant, at no expense to Landlord, in seeking and obtaining
required approvals. Landlord agrees that, other than Tenant's signs, no other
exterior signage shall be permitted to be installed on the Building except for
Building standard tenant identification signage.

          Landlord further agrees that, so long as no space in the Building or
the Adjacent Building is available for lease, it will not maintain a leasing
sign on the Property."

its entirety and replaced with the following:

          "10. Mechanics' Liens. The property shall not be subject in any way to

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

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."

attorneys, investigators and experts) in connection with loss of life, personal
injury or damage to property caused to any person in or about the Property
(other than the Premises) occasioned wholly or in part by the negligence of
Landlord or its Agents, except to the extent such loss, injury or damage was
caused by the negligence of Tenant or its Agents. In case any action or
proceeding is brought against Tenant and/or its Agents by reason of the
foregoing, Landlord, 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 Tenant and its Agents) designated by the insurer whose policy

counters of such bank in such location. The letter of credit shall be
irrevocable and shall impose no condition upon the beneficiary's right to draw
funds under it, other than a written statement by the beneficiary that Tenant
has committed a default of one or more of its obligations under the lease. The
beneficiary of the letter of credit shall be Landlord, and such letter of credit
shall be transferable by Landlord to any entity succeeding to Landlord's
interest in the Property, without cost to Landlord or its successors in

failure of Tenant to renew or replace the letter of credit in accordance with
the foregoing requirements shall be deemed a default by Tenant under the terms
of this lease which shall not require the giving of notice or the allowance of
any grace period, and shall entitle Landlord to immediately draw funds under the
letter of credit (an "Early Draw"), in addition to any other remedies provided
for in this lease or under applicable law. In the event of an Early Draw,
Landlord shall hold and apply the funds so drawn as if cash in such amount had
been posted by Tenant as the Security Deposit."

to be present with Tenant at the installation or removal.

     (e) Tenant shall maintain the Generator in a safe, good and orderly
condition. The installation, maintenance, repair and removal of the Generator
shall be performed at Tenant's sole expense in a manner which will not impair
the integrity of, damage or adversely affect the warranty applicable to, any
portion of the Property.

     (f) The Generator will remain Tenant's property throughout the Term of the
lease and, no later than the expiration or sooner termination of the Term, at
Tenant's sole expense, Tenant shall remove the Generator and all wiring
therefrom to and through the Building and repair any resulting damage, including
without limitation, damage to landscaping or paving, or, at Landlord's option,
Tenant shall also be responsible for restoring all affected areas to the
condition existing prior to the execution of this lease. Tenant shall comply
with all Laws and Requirements in connection with the removal of the Generator
and shall deliver to Landlord copies of all required permits and approvals in

Property therefor. Without limiting the foregoing, Tenant solely shall be
responsible for any damage or injury caused by or in any way relating to the
Generator, including, but not limited to, damage or injury to persons or
property, including the Property, caused by reason of any leaking of fuel
therefrom.

     (h) In the event the cost of Landlord's insurance on the Building is
increased as a result of the installation of the Generator, Tenant shall pay for
the increase in such insurance as set forth in subsection 7(c)(iv) of this
lease.

measures implemented by Landlord to control abuse of the parking areas,
including without limitation access control programs, tenant and guest vehicle
identification programs, and validated parking programs, provided that no such
validated parking program shall result in Tenant being charged for spaces to
which it has a right to free use under its lease. Each vehicle owner shall
promptly respond to any sounding vehicle alarm or horn, and failure to do so may
result in temporary or permanent exclusion of such vehicle from the parking
areas. Any vehicle which violates the parking regulations may be cited, towed at

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.

agreed to abide by them as a condition to Tenant's occupancy of the Premises.

     20. Tenant shall not burn candles, incense, matches or other ignitable
