2.  Lease of Premises. Landlord, in consideration of the covenants and
agreements to be performed by Tenant, and upon the terms and conditions
hereinafter stated, does hereby rent and lease unto Tenant, and Tenant does
hereby rent and lease from Landlord, certain premises (the "Demised Premises")
in the building (hereinafter referred to as "Building") located or to be
located on that certain tract of land (the "Land") more particularly described
in Exhibit "A" attached hereto and by this reference made a part hereof, which
Demised Premises are outlined in red or crosshatched on the floor plan attached
hereto as Exhibit "B" and by this reference made a part hereof, with no
easement for light, view or air included in the Demised Premises or being
granted hereunder. The obligations of Landlord and Tenant with respect to the
initial leasehold improvements to the Demised Premises are set forth in Exhibit
"C" attached hereto and by this reference made a part hereof. Landlord shall
cause the Demised Premises to be "ready for occupancy" (as defined in Exhibit
"C" attached hereto) not later than April 1, 1999, subject to force majeure,
delays caused by Tenant and Tenant's compliance with the terms and provisions
of Exhibit "C" attached hereto. In the event the Demised Premises are not ready
for occupancy on or before April 1, 1999 (the "Turnover Date"), Landlord shall
reimburse Tenant, as set forth below, for any rental expense actually incurred
by Tenant in excess of the rental expense Tenant would have incurred but for
the delay in the Turnover Date based on the rental rates in effect for the
month of March, 1999 (the "Excess Rent Payments"). The reimbursement obligation
set forth in the immediately preceding sentence shall apply only to Tenant's
office premises at the following locations:

     Inverness Office Park Building 10           22,152 Rentable Square Feet
     Inverness Office Park Building 31           15,872 Rentable Square Feet
     Meadow Brook Corporate Park Building 300    21,058 Rentable Square Feet

Such obligation of Landlord for Excess Rent Payments shall continue until the
Demised Premises are "ready for occupancy" as defined in Exhibit "C" attached
hereto. Notwithstanding the foregoing, Landlord shall have no obligation to
reimburse Tenant for any Excess Rent Payments if the Turnover Date shall be
delayed due to force majeure or delays caused by or within the reasonable
control of Tenant.

                                       2

The "Project" is comprised of the Building, the Land, the Building's parking
facilities, any walkways, covered walkways, tunnels or other means of access to
the Building and the Building's parking facilities, all common areas, including
any lobbies or plazas, and any other improvements or landscaping on the Land.
The Project is located in the development known as "Meadow Brook South" (the
"Development").

3.   Term. The term of this Lease ("Lease Term") shall commence on the Effective
Date, and, unless extended or sooner terminated as provided in this Lease, shall
end on the expiration of the Rental Term designated in Article 1(i) above,
which Rental Term shall commence on the Rental Commencement Date, unless the
Rental Commencement Date shall be other than the first day of a calendar month,
in which event the Rental Term shall commence on the first day of the calendar
month following the month in which the Rental Commencement Date occurs. Promptly
after the Rental Commencement Date, Landlord shall send to Tenant a Confirmation
Notice in the form of Exhibit "D" attached hereto and by this reference made a
part hereof, specifying the Rental Commencement Date, the date of expiration of
the Lease Term established in accordance herewith and certain other matters
Landlord may deem appropriate.

4.   Possession. Taking of possession by Tenant shall be deemed conclusively to
establish Tenant has accepted the Demised Premises as suitable for Tenant's
intended use and that Landlord's construction obligations with respect to the
Demised Premises have been completed and that the Demised Premises, to the
extent of Landlord's construction obligations with respect thereto, are in good
and satisfactory condition (subject to completion of any incomplete or
corrective items specified in a "punch list" approved by Landlord and Tenant).

5.   Rental Payments.

     (a)  Effective upon the Rental Commencement Date, and continuing thereafter
throughout the Lease Term, Tenant covenants and agrees to pay Landlord, all
Rent due and payable under this Lease, at the times and in the manner provided
in this Lease. As used in this Lease, the term "Rent" shall mean the Base Rental
(as hereinafter defined), Tenant's Forecast Additional Rental (as hereinafter
defined), Tenant's Additional Rental (as hereinafter defined), and any other
amounts that Tenant assumes or agrees to pay under the provisions of this Lease
that are owed to Landlord, including without limitation any and all other sums
that may become due by reason of any default of Tenant or failure on Tenant's
part to comply with the agreements, terms, covenants and conditions of this
Lease to be performed by Tenant. For both Tenant's and Landlord's accounting
purposes, it is agreed that Rent charges of every kind herein set forth shall
begin to accrue on the Rental Commencement Date and continue throughout the
Lease Term and any extensions or renewals thereof.

     With regard to payments of Base Rental and Tenant's Forecast Additional
Rental, the first installment shall be due, in advance, on the Rental
Commencement Date. Each subsequent installment, in an amount equal to one
twelfth (1/12) of the annual rate, shall be due, in advance, on the first day of
each month next ensuing after the Rental Commencement Date, and continuing
thereafter throughout the Lease Term and any extensions or renewals thereof.

     All Rent payable by Tenant hereunder to Landlord shall be paid, in lawful
money of the United States of America, to Landlord at the address provided for
payment of Rent or to such other payee or address as Landlord may designate in
writing to Tenant. Tenant shall pay all Rent and other sums of money as shall
become due from and payable by Tenant to Landlord under this Lease at the times
and in the manner provided in this Lease, without demand, deduction, set-off or
counterclaim.



                                       3
   7

     (b)  If the Rental Commencement Date is other than the first day of a
calendar month or if this Lease terminates on other than the last day of a
calendar month, then the installments of Base Rental and Tenant's Forecast
Additional Rental for such month or months shall be prorated on a daily basis.
Also, if the Rental Commencement Date occurs on other than the first day of a
calendar year, or if this Lease expires or is terminated on other than the last
day of a calendar year, Tenant's Additional Rental shall be prorated for such
commencement or termination year, as the case may be, by multiplying such
Tenant's Additional Rental by a fraction, the numerator of which shall be the
number of days of the Lease Term (from and after the Rental Commencement Date)
during the commencement or expiration or termination year, as the case may be,
and the denominator of which shall be 365, and the calculation described in
Article 8 hereof shall be made as soon as possible after the expiration or
termination of this Lease, Landlord and Tenant hereby agreeing that the
provisions relating to said calculation shall survive the expiration or
termination of this Lease.

     (c)  As security for Tenant's obligations to take possession of the Demised
Premises in accordance with the terms of this Lease and to comply with all of
Tenant's covenants, warranties and agreements hereunder, Tenant has deposited
with Landlord the Rent Deposit set forth in Article 1(l) above. Such amount
shall be applied by Landlord to the first monthly installment(s) of Base Rental
as they become due hereunder. In the event Tenant fails to take possession of
the Demised Premises as aforesaid or otherwise fails to comply with any of
Tenant's covenants, warranties or agreements hereunder, said sum shall be
retained by Landlord for application in reduction, but not in satisfaction, of
damages suffered by Landlord as a result of such breach by Tenant. Unless
otherwise required by State law, Landlord shall not be required to keep such
deposit separate from its general accounts.

     (d)  No payment by Tenant or acceptance by Landlord of an amount less than
the Rent herein stipulated or otherwise becoming due shall be deemed a waiver of
any other Rent due. No partial payment or endorsement on any check or any letter
accompanying such payment of Rent shall be deemed an accord and satisfaction,
but Landlord may accept such payment without prejudice to Landlord's right to
collect the balance of any Rent due under the terms of this Lease or any late
charge assessed against Tenant hereunder. All payments received by Landlord
shall be applied by Landlord as Landlord shall determine, regardless of any
notation that may be made on any check or any letter accompanying such payment.

6.   Base Rental.  Subject to adjustments in accordance with Article 7 and
paragraph 4.01(2) of Exhibit "G" below, from and after the Rental Commencement
Date, Tenant shall pay to Landlord a base annual rental (herein called "Base
Rental") equal to the Base Rental Rate set forth in Article 1(j) above
multiplied by the Rentable Floor Area of the Demised Premises set forth in
Article l(g) above. Payments of Base Rental shall be made at the times and in
the manner set forth in Article 5(a) hereinabove.

7.   Base Rental Escalation.

     (a)  As used in this Article 7, the term "Subsequent Year" shall mean each
Lease Year of the Lease Term following the first Lease Year. The term "Prior
Year" shall mean the Lease Year immediately preceding each Subsequent Year.

     (b)  On the first day of each Subsequent Year, the Base Rental Rate shall
be increased to an amount equal to the Base Rental Rate set forth below:


                               
          Second Lease Year       $17.61 per square foot of Rentable Floor Area
          Third Lease Year        $17.98 per square foot of Rentable Floor Area
          Fourth Lease Year       $18.36 per square foot of Rentable Floor Area




                                       4
   8


                               
          Fifth Lease Year        $18.76 per square foot of Rentable Floor Area
          Sixth Lease Year        $19.16 per square foot of Rentable Floor Area
          Seventh Lease Year      $19.58 per square foot of Rentable Floor Area
          Eighth Lease Year       $20.01 per square foot of Rentable Floor Area
          Ninth Lease Year        $20.45 per square foot of Rentable Floor Area
          Tenth Lease Year        $20.91 per square foot of Rentable Floor Area


8.   Additional Rental.

     (a)  Subject to the terms of this Article 8, from and after the Rental
Commencement Date, Tenant shall pay to Landlord "Tenant's Forecast Additional
Rental" (as defined in subparagraph (b) hereinbelow) and "Tenant's Additional
Rental" (as defined in subparagraph (c) hereinbelow). Payments of Tenant's
Forecast Additional Rental shall be made as set forth in Article 5(a).

     (b)  For purposes of this Lease, "Tenant's Forecast Additional Rental"
shall mean Landlord's reasonable estimate of Tenant's Additional Rental for the
coming calendar year or portion thereof. If at any time it appears to Landlord
that Tenant's Additional Rental for the current calendar year will vary from
Landlord's estimate by more than five percent (5%), Landlord shall have the
right to revise, by notice to Tenant, its estimate for such year, and subsequent
payments by Tenant for such year shall be based upon such revised estimate of
Tenant's Additional Rental. Failure to make a revision contemplated by the
immediately preceding sentence shall not prejudice Landlord's right to collect
the full amount of Tenant's Additional Rental. Prior to the Rental Commencement
Date and thereafter prior to the beginning of each calendar year during the
Lease Term, including any extensions thereof, Landlord shall present to Tenant a
statement of Tenant's Forecast Additional Rental for such calendar year;
provided, however, that if such statement is not given prior to the beginning of
any calendar year as aforesaid, Tenant shall continue to pay during the next
ensuing calendar year on the basis of the amount of Tenant's Forecast Additional
Rental payable during the calendar year just ended until the month after such
statement is delivered to Tenant.

     (c)  For purposes of this Lease, "Tenant's Additional Rental" shall mean
for each calendar year (or portion thereof) the Operating Expense Amount
(defined below), less the Expense Stop set forth in Article 1(s), multiplied by
the number of square feet of Rentable Floor Area of the Demised Premises. As
used herein, "Operating Expense Amount" shall mean an amount equal to (x) plus
(y) where:

          (x) equals the amount of Operating Expenses (as defined below) for
          such calendar year divided by the greater of (i) 95% of the number of
          square feet of Rentable Floor Area of the Building, or (ii) the total
          number of square feet of Rentable Floor Area occupied in the Building
          for such calendar year on an average annualized basis; provided,
          however, if the Operating Expenses actually incurred by Landlord are
          lower than would be incurred if at least 95% of the Building were
          occupied or if Landlord shall not furnish any particular item(s) of
          work or services (the cost of which would otherwise be included within
          Operating Expenses) to portions of the Building because (A) such
          portions are not occupied, (B) such item of work or services is not
          required or desired by the tenant of such portion, (C) such tenant is
          itself obtaining such item of work or services, or (D) of any other
          reason, then appropriate adjustments shall be made to determine
          Operating Expenses for such calendar year as though the Building were
          actually occupied to the extent of the greater of (i) or (ii) above
          and as though Landlord had furnished such item of work or services to
          the greater of (i) or (ii) above; and



                                       5
   9

          (y) equals a management fee contribution equal to three percent (3%)
          of the difference between Tenant's Base Rental Rate and the Expense
          Stop, plus three percent (3%) of the per square foot amount described
          in (x) above.

     (d)  Within one hundred twenty (120) days after the end of the calendar
year in which the Rental Commencement Date occurs and of each calendar year
thereafter during the Lease Term, or as soon thereafter as practicable, Landlord
shall provide Tenant a statement showing the Operating Expenses for said
calendar year, and a statement comparing Tenant's Forecast Additional Rental
with Tenant's Additional Rental. In the event Tenant's Forecast Additional
Rental exceeds Tenant's Additional Rental for said calendar year, Landlord shall
credit such amount against Rent then owing or next due hereunder or, if the
Lease Term has expired or is about to expire, refund such excess to Tenant if
Tenant is not in default under this Lease (in the instance of a default such
excess shall be held as additional security for Tenant's performance, may be
applied by Landlord to cure any such default, and shall not be refunded until
any such default is cured). In the event that the Tenant's Additional Rental
exceeds Tenant's Forecast Additional Rental for said calendar year, Tenant
covenants and agrees to pay Landlord, within thirty (30) days of receipt of the
statement, an amount equal to such difference, Landlord's failure to provide
Tenant said statement within one hundred twenty (120) days as set forth above
shall not affect Tenant's obligation for payment of any amounts due under
Article 8. The provisions of this Lease concerning the payment of Tenant's
Additional Rental shall survive the expiration or earlier termination of this
Lease.

     (e)  For so long as Tenant is not in default under this Lease, Landlord's
books and records pertaining to the calculation of Operating Expenses for any
calendar year within the Lease Term may be audited by an authorized
representative of Tenant at Tenant's expense, at any time within twelve (12)
months after the end of each such calendar year; provided that Tenant shall give
Landlord not less than thirty (30) days' prior written notice of any such audit.
For purposes hereof, an authorized representative of Tenant shall mean a bona
fide employee of Tenant, any of the "big six" accounting firms, or any other
party reasonably approved in writing by Landlord. In no event shall an
authorized representative of Tenant include the owner of any office building in
the metropolitan area in which the Demised Premises are located or any affiliate
of such owner. Prior to the commencement of such audit, Tenant shall cause its
authorized representative to agree in writing for the benefit of Landlord that
such representative will keep the results of the audit confidential and that
such representative will not disclose or divulge the results of such audit
except to Tenant and Landlord and except in connection with any dispute between
Landlord and Tenant relating to Operating Expenses. Such audit shall be
conducted during reasonable business hours at Landlord's office where Landlord's
books and records are maintained. Tenant shall cause a written audit report to
be prepared by its authorized representative following any such audit and shall
provide Landlord with a copy of such report promptly after receipt thereof by
Tenant. If Landlord's calculation of Tenant's Additional Rental for the audited
calendar year was incorrect, then Tenant shall be entitled to a prompt refund of
any overpayment or Tenant shall promptly pay to Landlord the amount of any
underpayment, as the case may be.

Article 9[a][1] above);

          5.   the cost of any items for which Landlord is reimbursed by
insurance, condemnation or otherwise, except for costs reimbursed pursuant to

10.  Tenant Taxes; Rent Taxes. Tenant shall pay promptly when due all taxes

shall be made on a timely basis, as provided in this Lease, and shall be payable
to Landlord or as Landlord may otherwise designate. All such payments shall be

Article l(b) above or at such other place as Landlord may designate from time to

     (a)  Tenant shall use and occupy the Demised Premises solely for the
Use set forth in Article 1(r), and no other purposes, and in accordance with all

and the rules and regulations attached hereto as Exhibit "G" and made a part
hereof (the "Rules and Regulations"). The occupancy rate of the Demised Premises
shall in no event be more than one (1) person per 143 square feet of Rentable
Floor Area of the Demised Premises; and

     (b)  Tenant covenants and agrees to abide by the Rules and Regulations in
all respects as now set forth and attached hereto as Exhibit "G" or as hereafter
promulgated by Landlord. All Rules and Regulations for the Building shall be
uniformly applied to all tenants in the Building, and Landlord will not be
arbitrary in effecting changes in the Rules and Regulations. Landlord shall have
the right at all times during the Lease Term, with notice to Tenant, to publish
and promulgate and thereafter enforce such rules and regulations or changes in
the existing Rules and Regulations as it may reasonably deem necessary in its
sole discretion to protect the tenantability, safety, operation, and welfare of
the Demised Premises, the Project and the Development; and

     (c)  Notwithstanding anything to the contrary in this Lease, in no event
shall Tenant, its employees, agents, contractors, visitors and invitees in the
aggregate utilize more than 1 parking space for each 143 square feet of the
Rentable Floor Area of the Demised Premises.

14.  Alterations and Installations. Except for any initial improvement of the
Demised Premises pursuant to Exhibit "C" which shall be governed by the
provisions of said Exhibit "C", Tenant shall not make, suffer or permit to be
made any alterations, additions or improvements to or of the Demised Premises or
any part thereof, or attach any fixtures or equipment thereto, without first
obtaining Landlord's written consent, which consent shall not be unreasonably
withheld. Any such alterations, additions or improvements to the Demised
Premises shall be made subject to Landlord's requirements and at Tenant's sole
cost and expense. All such alterations, additions and improvements shall become
Landlord's property at the expiration or earlier termination of the Lease Term
and shall remain on the Demised Premises without compensation to Tenant unless
Landlord elects by notice to Tenant to have Tenant remove such alterations,
additions and improvements, in which event, notwithstanding any contrary
provisions respecting such alterations, additions and improvements contained in
Article 33 hereof, Tenant shall promptly restore, at its sole cost and expense,
the Demised Premises to its condition prior to the installation of such
alterations, additions and improvements, normal wear and tear excepted.

15.  Repairs.

     (a)  Landlord shall maintain in good order and repair, subject to normal
wear and tear and subject to casualty and condemnation, the Building (excluding
the Demised Premises and other portions



                                       10
   14

of the Building leased to other tenants), the Building parking facilities, the
public areas and the landscaped areas. Notwithstanding the foregoing obligation,
the cost of any repairs or maintenance to the foregoing necessitated by the
intentional acts or negligence of Tenant or its agents, contractors, employees,
invitees, licensees, tenants or assigns, shall be borne solely by Tenant and
shall be deemed Rent hereunder and shall be reimbursed by Tenant to Landlord
upon demand. Landlord shall not be required to make any repairs or improvements
to the Demised Premises except structural repairs necessary for safety and
tenantability.

     (b)  Tenant covenants and agrees that it will take good care of the Demised
Premises and all alterations, additions and improvements thereto and will keep
and maintain the same in good condition and repair, except for normal wear and
tear. Tenant shall at once report, in writing, to Landlord any defective or
dangerous condition known to Tenant. To the fullest extent permitted by law,
Tenant hereby waives all rights to make repairs at the expense of Landlord or in
lieu thereof to vacate the Demised Premises as may be provided by any law,
statute or ordinance now or hereafter in effect. Landlord has no obligation and
has made no promise to alter, remodel, improve, repair, decorate or paint the
Densed Premises or any part thereof, except as specifically and expressly herein
set forth.

16.  Landlord's Right of Entry. Landlord shall retain duplicate keys to all
doors of the Demised Premises, and Landlord and its agents, employees and
independent contractors shall have the right to enter the Demised Premises at
reasonable hours to inspect and examine same, to make repairs, additions,
alterations, and improvements, to exhibit the Demised Premises to mortgagees,
prospective mortgagees, purchasers or tenants, and to inspect the Demised
Premises to ascertain that Tenant is complying with all of its covenants and
obligations hereunder, all without being liable to Tenant in any manner
whatsoever for any damages arising therefrom; provided, however, that Landlord
shall, except in case of emergency, afford Tenant such prior notification of an
entry into the Demised Premises as shall be reasonably practicable under the
circumstances. Landlord shall be allowed to take into and through the Demised
Premises any and all materials that may be required to make such repairs,
additions, alterations or improvements. During such time as such work is being
carried on in or about the Demised Premises, the Rent provided herein shall not
abate, and Tenant waives any claim or cause of action against Landlord for
damages by reason of interruption of Tenant's business or loss of profits
therefrom because of the prosecution of any such work or any part thereof.

17.  Insurance. From and after the Rental Commencement Date, Tenant shall
procure at its expense and maintain throughout the remainder of the Lease Term a
policy or policies of special form/all-risk insurance insuring the full
replacement cost of its furniture, fixtures, equipment, supplies, and other
property owned, leased, held or possessed by it and contained in the Demised
Premises, together with the excess value of the improvements to the Demised
Premises over the Construction Allowance, and worker's compensation insurance as
required by applicable law. From and after the Rental Commencement Date, Tenant
shall also procure at its expense and maintain throughout the remainder of the
Lease Term a policy or policies of commercial general liability insurance,
insuring Tenant, Landlord and any other person designated by Landlord, against
any and all liability for injury to or death of a person or persons and for
damage to property occasioned by or arising out of any construction work being
done on the Demised Premises, or arising out of the condition, use, or occupancy
of the Demised Premises, or in any way occasioned by or arising out of the
activities of Tenant, its agents, contractors, employees, guests, or licensees
in the Demised Premises, or other portions of the Building or the Project or the
Development, the limits of such policy or policies to be in combined single
limits for both damage to property and personal injury and in amounts not less
than Three Million Dollars ($3,000,000) for each occurrence, with deductibles
acceptable to Landlord. Such insurance shall, in addition, extend to any
liability of Tenant arising out of the indemnities provided for in this Lease.
Tenant shall also carry such other types of insurance in form and amount which
Landlord shall reasonably deem to be prudent for



                                       11
   15

Tenant to carry, should the circumstances or conditions so merit Tenant carrying
such type of insurance, provided that such other insurance is then customarily
carried by tenants in other comparable buildings in the metropolitan area in
which the Project is located. All insurance policies procured and maintained by
Tenant pursuant to this Article 17 shall name Landlord and any additional
parties designated by Landlord as additional insureds, shall be carried with
companies licensed to do business in the State having a rating from Best's
Insurance Reports of not less than A-/X, and shall be non-cancelable and not
subject to material change except after thirty (30) days' written notice to
Landlord. Such policies or duly executed certificates of insurance with respect
thereto, accompanied by proof of payment of the premium therefor, shall be
delivered to Landlord prior to the date Tenant first enters upon the Demised
Premises (for installation of Tenant's improvements and fixtures, or otherwise),
and renewals of such policies shall be delivered to Landlord at least thirty
(30) days prior to the expiration of each respective policy term.

Landlord shall procure and maintain at its expense (but with the expense to be
included in Operating Expenses) throughout the Lease Term a policy or policies
of special form/all-risk (including rent loss coverage) real and personal
property insurance covering the Project (including the leasehold improvements in
the Demised Premises up to the amount of the Construction Allowance, but
excluding Tenant's personal property and equipment), in an amount equal to the
full insurable replacement cost thereof as such may increase from time to time
(but such insurance may provide for a commercially reasonable deductible), and
in an amount sufficient to comply with any co-insurance requirements in such
policy, and a policy of workers' compensation insurance, if any, as required by
applicable law. In addition, Landlord shall procure and maintain at its expense
(but with the expense to be included in Operating Expenses) and shall thereafter
maintain throughout the Lease Term, a commercial general liability insurance
policy covering the Project with combined single limits for both damage to
property and personal injury of not less than Three Million Dollars ($3,000,000)
per occurrence, subject to annual aggregate limits of not less than Five Million
Dollars ($5,000,000). Landlord may also carry such other types of insurance in
form and amounts which Landlord shall determine to be appropriate from time to
time, and the cost thereof shall be included in Operating Expenses. All such
policies procured and maintained by Landlord pursuant to this Article 17 shall
be carried with companies licensed to do business in the State. Any insurance
required to be carried by Landlord hereunder may be carried under blanket
policies covering other properties of Landlord and/or its partners and/or their
respective related or affiliated corporations so long as such blanket policies
provide insurance at all times for the Project as required by this Lease.

18.  Waiver of Subrogation. Landlord and Tenant shall each have included in all
policies of fire, extended coverage, business interruption and loss of rents
insurance respectively obtained by them covering the Demised Premises, the
Building and contents therein, a waiver by the insurer of all right of
subrogation against the other in connection with any loss or damage thereby
insured against. Any additional premium for such waiver shall be paid by the
primary insured. To the full extent permitted by law, Landlord and Tenant each
waives all right of recovery against the other for, and agrees to release the
other from liability for, loss or damage to the extent such loss or damage is
covered by valid and collectible insurance in effect at the time of such loss or
damage or would be covered by the insurance required to be maintained under this
Lease by the party seeking recovery.

this Lease:



                                       13
   17

          (i)    terminate this Lease, in which event Tenant shall immediately
surrender the Demised Premises to Landlord and if Tenant fails to do so,
Landlord may without prejudice to any other remedy which it may have for
possession or arrearage in Rent, enter upon and take possession of the Demised
Premises and expel or remove Tenant and any other person who may be occupying
said Demised Premises or any part thereof without being liable for prosecution
or any claim of damages therefor; Tenant hereby agreeing to pay to Landlord on
demand the amount of all loss and damage which Landlord may suffer by reason of
such termination, whether through inability to relet the Demised Premises on
satisfactory terms or otherwise;

          (ii)   terminate Tenant's right of possession, without terminating
this Lease, and enter upon and take possession of the Demised Premises and expel
or remove Tenant and any other person who may be occupying said Demised Premises
or any part thereof, by entry, dispossessory suit or otherwise, without thereby
releasing Tenant from any liability hereunder, and without being liable for
prosecution or any claim of damages therefor and, if Landlord so elects, make
such alterations, decoration and repairs as, in Landlord's judgment, may be
necessary to relet the Demised Premises, and Landlord may, but shall be under no
obligation to do so (except as may be provided by State law), relet the Demised
Premises or any portion thereof in Landlord's or Tenant's name, but for the
account of Tenant, for such term or terms (which may be for a term extending
beyond the Lease Term) and at such rental or rentals and upon such other terms
as Landlord may deem advisable, with or without advertisement, and by private
negotiations, and receive the rent therefor, Tenant hereby agreeing to pay to
Landlord the deficiency, if any, between all Rent reserved hereunder and the
total rental applicable to the Lease Term hereof obtained by Landlord
re-letting, and Tenant shall be liable for Landlord's expenses in redecorating

including broker's commissions and lease assumptions, and in no event shall
Tenant be entitled to any rentals received by Landlord in excess of the amounts
due by Tenant hereunder; and any such demand, reentry and taking possession of
the Demised Premises by Landlord shall not of itself constitute an acceptance by
Landlord of a surrender of this Lease or of the Demised Premises by Tenant and
shall not of itself constitute a termination of this Lease by Landlord; or

          (iii)  enter upon the Demised Premises without being liable for
prosecution or any claim of damages therefor, and do whatever Tenant is
obligated to do under the terms of this Lease; and Tenant agrees to reimburse

charges and assessments which in Landlord's reasonable determination would
become due and payable during the remainder of the Lease Term (including, but
not limited to, increases in Rent pursuant to Article 7 hereof) to be
immediately due and payable; and thereupon all Rent and other charges due
hereunder to the end of the initial term or any then in effect renewal term,
shall be accelerated.

     (c)  Pursuit of any of the foregoing remedies shall not preclude pursuit of
any other remedy herein provided or any other remedy provided by law or at
equity, nor shall pursuit of any remedy herein provided constitute an election
of remedies thereby excluding the later election of an alternate remedy, or a
forfeiture or waiver of any Rent or other charges and assessments payable by
Tenant and due to Landlord hereunder or of any damages accruing to Landlord by
reason of violation of any of the terms, covenants, warranties and provisions
herein contained. No reentry or taking possession of the Demised Premises by
Landlord or any other action taken by or on behalf of Landlord shall be
construed to be an



                                       14
   18

acceptance of a surrender of this Lease or an election by Landlord to terminate
this Lease unless written notice of such intention is given to Tenant.
Forbearance by Landlord to enforce one or more of the remedies herein provided
upon an event of default shall not be deemed or construed to constitute a waiver
of such default. In determining the amount of loss or damage which Landlord may
suffer by reason of termination of this Lease or the deficiency arising by
reason of any reletting of the Demised Premises by Landlord as above provided,
allowance shall be made for the expense of repossession. Tenant agrees to pay to
Landlord all costs and expenses incurred by Landlord in the enforcement of this
Lease, including, without limitation, the fees of Landlord's attorneys as
provided in Article 26 hereof.

20.  Waiver of Breach. No waiver of any breach of the covenants, warranties,
agreements, provisions, or conditions contained in this Lease shall be construed
as a waiver of said covenant, warranty, provision, agreement or condition or of
any subsequent breach thereof, and if any breach shall occur and afterwards be
compromised, settled or adjusted, this Lease shall continue in full force and
effect as if no breach had occurred.

21.  Assignment and Subletting. Tenant shall not, without the prior written
consent of Landlord, assign this Lease or any interest herein or in the Demised
Premises, or mortgage, pledge, encumber, hypothecate or otherwise transfer or
sublet the Demised Premises or any part thereof or permit the use of the Demised
Premises by any party other than Tenant. Consent to one or more such transfers
or subleases shall not destroy or waive this provision, and all subsequent
transfers and subleases shall likewise be made only upon obtaining the prior
written consent of Landlord. Without limiting the foregoing prohibition, in no
event shall Tenant assign this Lease or any interest herein, whether directly,
indirectly or by operation of law, or sublet the Demised Premises or any part
thereof or permit the use of the Demised Premises or any part thereof by any
party (i) if the proposed assignee or subtenant is a party who would, or whose
use would, detract from the character of the Building as a first class office
building (such as, without limitation, a dental, medical or chiropractic office
or a governmental office), or conflict with the uses, practices or requirements
of this Lease, or the Building; (ii) if the proposed use of the Demised Premises
shall involve an occupancy rate of more than one (1) person per 143 square feet
of Rentable Floor Area of the Demised Premises, (iii) if the proposed assignment
or subletting shall be to a governmental subdivision or agency or any person or
entity who enjoys diplomatic or sovereign immunity, (iv) if such proposed
assignee or subtenant is an existing tenant of the Building, or (v) if such
proposed assignment, subletting or use would contravene any restrictive covenant
(including any exclusive use) granted to any other tenant of the Building.
Sublessees or transferees of the Demised Premises for the balance of the Lease
Term shall become directly liable to Landlord for all obligations of Tenant
hereunder, without relieving Tenant (or any guarantor of Tenant's obligations
hereunder) of any liability therefor, and Tenant shall remain obligated for all
liability to Landlord arising under this Lease during the entire remaining Lease
Term including any extensions thereof, whether or not authorized herein. If
Tenant is a partnership, a limited liability company or a limited liability
partnership, a withdrawal or change, whether voluntary, involuntary or by
operation of law, of partners or members owning a controlling interest in the
Tenant shall be deemed a voluntary assignment of this Lease and subject to the
foregoing provisions. If Tenant is a corporation, any dissolution, merger,
consolidation or other reorganization of Tenant, or the sale or transfer of a
controlling interest in the capital stock of Tenant, shall be deemed a voluntary
assignment of this Lease and subject to the foregoing provisions. Landlord may,
as a prior condition to considering any request for consent to an assignment or
sublease, require Tenant to obtain and submit current financial statements of
any proposed subtenant or assignee. In the event Landlord consents to an
assignment or sublease, Tenant shall pay to Landlord a fee to cover Landlord's
accounting costs plus any legal fees incurred by Landlord as a result of the
assignment or sublease. Landlord may require an additional security deposit from
the assignee or subtenant as a condition of its consent. Any consideration, in
excess of the Rent and other charges and sums due and payable by Tenant under
this Lease, paid to Tenant by any assignee of this Lease for its assignment, or



                                       15
   19

by any sublessee under or in connection with its sublease, or otherwise paid to
Tenant by another party for use and occupancy of the Demised Premises or any
portion thereof, shall be promptly remitted by Tenant to Landlord as additional
rent hereunder and Tenant shall have no right or claim thereto as against
Landlord. No assignment of this Lease consented to by Landlord shall be
effective unless and until Landlord shall receive an original assignment and
assumption agreement, in form and substance satisfactory to Landlord, signed by
Tenant and Tenant's proposed assignee, whereby the assignee assumes due
performance of this Lease to be done and performed for the balance of the then
remaining Lease Term of this Lease. No subletting of the Demised Premises, or
any part thereof, shall be effective unless and until there shall have been
delivered to Landlord an agreement, in form and substance satisfactory to
Landlord, signed by Tenant and the proposed sublessee, whereby the sublessee
acknowledges the right of Landlord to continue or terminate any sublease, in
Landlord's sole discretion, upon termination of this Lease, and such sublessee
agrees to recognize and attorn to Landlord in the event that Landlord elects
under such circumstances to continue such sublease.

     Notwithstanding anything contained in this Lease which may be to the
contrary, in the event Tenant shall assign this Lease or sublet the Demised
Premises in contravention of this Article 21, or if Tenant shall otherwise, by
operation of law, cease to be the sole occupant of the Demised Premises, same
shall be deemed a material default of Tenant, and, in addition to any other
rights or remedies Landlord may have with respect to such failure, Landlord may
also charge and collect from Tenant (and/or the occupant of the Demised
Premises) as Base Rental, an amount equal to 150% of the Base Rental otherwise
reserved and payable under this Lease until such time as Tenant shall have
caused compliance with the terms of this Lease. Occupancy or possession of the
Demised Premises shall cause said unapproved assignee, sublessee, or occupant to
be liable directly to Landlord for all amounts chargeable under this Lease,
without the granting thereto of a right of possession of the Demises Premises.
Acceptance by Landlord of any Rent payable hereunder made by anyone other than
Tenant as named herein shall under no circumstances in and of itself be deemed
an approval by Landlord of any assignment or subletting without compliance with
this Article 21.

22.  Destruction.

     (a)  If the Demised Premises are damaged by fire or other casualty, the
same shall be repaired or rebuilt as speedily as practical under the
circumstances at the expense of the Landlord (subject to subparagraph (c)
below], unless this Lease is terminated as provided in this Article 22, and
during the period required for restoration, a just and proportionate part of
Base Rental shall be abated until the Demised Premises are repaired or rebuilt.

     (b)  If the Demised Premises are (i) damaged to such an extent that repairs
cannot, in Landlord's judgment, be completed within nine (9) months after the
date of the casualty or (ii) damaged or destroyed as a result of a risk which is
not insured under standard special form/all-risk insurance policies, or (iii)
damaged or destroyed during the last eighteen (18) months of the Lease Term, or
if the Building is damaged in whole or in part (whether or not the Demised
Premises are damaged), to such an extent that the Building cannot, in Landlord's
judgment, be operated economically as an integral unit, then and in any such
event Landlord may at its option terminate this Lease by notice in writing to
the Tenant within sixty (60) days after the date of such occurrence. Landlord
shall give notice in writing to Tenant within one hundred twenty (120) days
after the date of such occurrence whether or not in Landlord's judgment such
repairs can be completed within nine (9) months after the date of the casualty.
If the Demised Premises are damaged to such an extent that repairs cannot, in
Landlord's judgment, be completed within nine (9) months after the date of the
casualty or if the Demised Premises are substantially damaged during the last
eighteen (18) months of the Lease Tenn, then in either such event Tenant may
elect to terminate this Lease by notice in writing to Landlord within fifteen
(15) days after



                                       16
   20

Tenant's receipt of such notice from Landlord. Unless Landlord or Tenant elects
to terminate this Lease as hereinabove provided, this Lease will remain in full
force and effect and Landlord shall repair such damage at its expense to the
extent required in this Article as expeditiously as possible under the
circumstances.

     (c)  If Landlord should elect or be obligated pursuant to subparagraph (a)
above to repair or rebuild because of any damage or destruction, Landlord's
obligation shall be limited to the original Building and the leasehold
improvements in the Demised Premises (to the extent such leasehold improvements
can be restored for the amount of the Construction Allowance applicable thereto)
and shall not extend to any fumiture, equipment, supplies or other personal
property owned or leased by Tenant, its employees, contractors, invitees or
licensees. If the cost of performing such repairs and restoration exceeds the
actual proceeds of insurance paid or payable to Landlord on account of such
casualty, or if Landlord's mortgagee or the lessor under a ground or underlying
lease shall require that any insurance proceeds from a casualty loss be paid to
it, Landlord may terminate this Lease unless Tenant, within fifteen (15) days
after demand therefor, deposits with Landlord a sum of money sufficient to pay
the difference between the cost of repair and the proceeds of the insurance
available to Landlord for such purpose.

     (d)  In no event shall Landlord be liable for any loss or damage sustained
by Tenant by reason of casualties mentioned hereinabove or any other accidental
casualty.

23.  Landlord's Lien. Landlord shall at all times have a valid first lien upon
all of the personal property of Tenant situated in the Demised Premises to
secure payment of Rent and other sums and charges due hereunder from Tenant to
Landlord and to secure the performance by Tenant of each and all of the
covenants, warranties, agreements and conditions hereof; provided that Landlord
will agree to subordinate such lien, upon terms and conditions reasonably
satisfactory to Landlord, to any first lien securing Tenant's financing of such
personal property or any part thereof. Said personal property shall not be
removed from the Demised Premises without the consent of Landlord until all
arrearages in Rent and other charges as well as any and all other sums of money
due hereunder shall first have been paid and discharged and until this Lease and
all of the covenants, conditions, agreements and provisions hereof have been
fully performed by Tenant. Tenant shall from time to time execute any financing
statements and other instruments necessary to perfect the security interest
granted herein. The lien herein granted may be foreclosed in the manner and form
provided by law for the foreclosure of security instruments or chattel
mortgages, or in any other manner provided by law. This Lease is intended as and
constitutes a security agreement within the meaning of the Uniform Commercial
Code of the State.

24.  Tenant's Waiver of Redemption and with Regard to Billings. Tenant hereby
expressly waives any and all rights of redemption granted by or under any
present or future laws in the event of Tenant being evicted or dispossessed for
any cause, or in the event of Landlord obtaining possession of the Demised
Premises by reason of the violation by Tenant of any of the covenants and
conditions of this Lease or otherwise. The rights given to Landlord herein are
in addition to any rights that may be given to Landlord by any statute or
otherwise. Except as provided in Article 8(e), Tenant's failure to object to any
statement, invoice or billing rendered by Landlord within a period of thirty
(30) days after receipt thereof shall constitute Tenant's acquiescence with
respect thereto and shall render such statement, invoice or billing an account
stated between Landlord and Tenant.

25.  Services by Landlord. Landlord shall provide the Building Standard Services
described on Exhibit "E" attached hereto and by reference made a part hereof.
Any services requested or required to be supplied to Tenant in excess of the
Building Standard Services shall be at Tenant's sole cost and expense and shall
be paid for by Tenant promptly upon invoice therefor, which invoice may include



                                       17
   21

Landlord's administrative costs and a fee of 10% for such provision. Nothing
herein shall be deemed to require Landlord to provide to Tenant any services in
excess of the Building Standard Services.

26.  Attorneys' Fees and Homestead. If any Rent or other debt owing by Tenant to
Landlord hereunder is collected by or through an attorney-at-law, Tenant agrees
to pay an additional amount equal to fifteen percent (15%) of such sum as
attorney's fees. If Landlord uses the services of any attorney in order to
secure compliance with any other provisions of this Lease, to recover damages
for any breach or default of any other provisions of this Lease, or to terminate
this Lease or evict Tenant, Tenant shall reimburse Landlord upon demand for any
and all attorney's fees and expenses so incurred by Landlord. Tenant waives all
homestead rights and exemptions which it may have under any law as against any
obligation owing under this Lease, and assigns to Landlord its homestead and
exemptions to the extent necessary to secure payment and performance of its
covenants and agreements hereunder.

27.  Time. Time is of the essence of this Lease, and whenever a certain day is
stated for payment or performance of any obligation of Tenant or Landlord, the
same enters into and becomes a part of the consideration hereof.

28.  Subordination and Attornment.

     (a)  Subject to the provisions of this Article, Tenant agrees that this
Lease and all rights of Tenant hereunder are and shall be subject and
subordinate to any ground or underlying lease which may now or hereafter be in
effect regarding the Project or any component thereof, to any mortgage now or
hereafter encumbering the Demised Premises or the Project or any component
thereof, to all advances made or hereafter to be made upon the security of such
mortgage, to all amendments, modifications, renewals, consolidations,
extensions, and restatements of such ground lease or mortgage, and to any
replacements and substitutions for such ground lease or mortgage. The terms of
this provision shall be self-operative and no further instrument of
subordination shall be required. Upon request of any party in interest, Tenant
shall execute promptly such instrument or certificates as may be reasonably
required to carry out the intent hereof, whether said requirement is that of
Landlord or any other party in interest, including, without limitation, any
ground lessor or mortgagee. Landlord is hereby irrevocably vested with full
power and authority as attorney-in-fact for Tenant and in Tenant's name, place
and stead, to subordinate Tenant's interest under this Lease to the lien or
security title of any ground lease or mortgage and to any future instrument
amending, modifying, renewing, consolidating, extending, restating, replacing or
substituting any such ground lease or mortgage.

     (b)  If any mortgagee, or any lessor under a ground or underlying lease,
elects to have this Lease superior to its mortgage or lease and signifies its
election in the instrument creating its lien or lease or by separate recorded
instrument, then this Lease shall be superior to such mortgage or lease, as the
case may be. The term "mortgage", as used in this Lease, includes any deed to
secure debt, deed of trust or security deed and any other instrument creating a
lien or conveying real property or any interest therein, in connection with any
other method of financing or refinancing. The term "mortgagee", as used in this
Lease, refers to the holder(s) of the indebtedness secured by a mortgage.

     (c)  In the event any proceedings are brought for the foreclosure of, or in
the event of exercise of the power of sale under, any mortgage covering the
Demised Premises or the Project, or in the event the interests of Landlord under
this Lease shall be transferred by reason of deed in lieu of foreclosure or
other legal proceedings, or in the event of termination of any lease under which
Landlord may hold title, Tenant shall, at the option of the transferee or
purchaser at foreclosure or under power of sale, or the lessor of the Landlord
upon such lease termination, as the case may be (sometimes hereinafter called
"such person"), attorn to such person and shall recognize and be bound and
obligated hereunder to such



                                       18
   22

person as the Landlord under this Lease; provided, however, that no such person
shall be (i) bound by any payment of Rent for more than one (1) month in
advance, except prepayments in the nature of security for the performance by
Tenant of its obligations under this Lease (and then only if such prepayments
have been deposited with and are under the control of such person); (ii) bound
by any amendment or modification of this Lease made without the express written
consent of the mortgagee or lessor of the Landlord, as the case may be; (iii)
obligated to cure any defaults under this Lease of any prior landlord (including
Landlord); (iv) liable for any act or omission of any prior landlord (including
Landlord); (v) subject to any offsets or defenses which Tenant might have
against any prior landlord (including Landlord); or (vi) bound by any warranty
or representation of any prior landlord (including Landlord) relating to work
performed by any prior landlord (including Landlord) under this Lease. Tenant
agrees to execute any attornment agreement not in conflict herewith requested by
Landlord, the mortgagee or such person. Tenant's obligation to attorn to such
person shall survive the exercise of any such power of sale, foreclosure or
other proceeding. Tenant agrees that the institution of any suit, action or
other proceeding by any mortgagee to realize on Landlord's interest in the
Demised Premises or the Building pursuant to the powers granted to a mortgagee
under its, mortgage, shall not, by Operation of law or otherwise, result in the
cancellation or termination of the obligations of the Tenant hereunder. Landlord
and Tenant agree that notwithstanding that this Lease is expressly subject and
subordinate to any mortgages, any mortgagee, its successors and assigns, or
other holder of a mortgage or of a note secured thereby, may sell the Demised
Premises or the Building, in the manner provided in the mortgage and may, at the
option of such mortgagee, its successors and assigns, or other holder of the
mortgage or note secured thereby, make such sale of the Demised Premises or
Building subject to this Lease.

29.  Estoppel Certificates. Within ten (10) days after request therefor by
Landlord, Tenant agrees to execute and deliver to Landlord in recordable form an
estoppel certificate addressed to Landlord, any mortgagee or assignee of
Landlord's interest in, or purchaser of, the Demised Premises or the Building or
any part thereof, certifying (if such be the case) that this Lease is unmodified
and is in full force and effect (and if there have been modifications, that the
same is in full force and effect as modified and stating said modifications);
certifying that there are no defenses or offsets against the enforcement thereof
or stating those claimed by Tenant; stating the date to which Rent and other
charges have been paid; certifying that there are no defaults, or events which,
with the giving of notice or the passage of time would be an event of default,
under this Lease; and certifying as to any other matters which may reasonably be
requested. Such certificate shall also include such other information as may
reasonably be required by such mortgagee, proposed mortgagee, assignee,
purchaser or Landlord. Any such certificate may be relied upon by Landlord, any
mortgagee, proposed mortgagee, assignee, purchaser and any other party to whom
such certificate is addressed.

30.  No Estate. This Lease shall create the relationship of landlord and tenant
only between Landlord and Tenant and no estate shall pass out of Landlord.

31.  Cumulative Rights. All rights, powers and privileges conferred hereunder
upon the parties hereto shall be cumulative to, but not restrictive of, or in
lieu of those conferred by law.

32.  Holding Over. If Tenant remains in possession after expiration or
termination of the Lease Term with or without Landlord's written consent, Tenant
shall become a tenant-at-sufferance, and there shall be no renewal of this Lease
by operation of law. During the period of any such holding over, all provisions
of this Lease shall be and remain in effect except that the monthly rental for
the first three (3) months of such holdover period shall be 125% of, and for all
months thereafter shall be 150% of, the amount of Rent (including any
adjustments as provided herein) payable for the last full calendar month of the
Lease Term including renewals or extensions. The inclusion of the preceding
sentence in this Lease shall not be construed as Landlord's consent for Tenant
to hold over.



                                       19
   23

33.  Surrender of Premises. Upon the expiration or other termination of this
Lease, Tenant shall quit and surrender to Landlord the Demised Premises and
every part thereof and all alterations, additions and improvements thereto,
broom clean and in good condition and state of repair, reasonable wear and tear
only excepted. If Tenant is not then in default, Tenant shall remove all
personalty and equipment not attached to the Demised Premises which it has
placed upon the Demised Premises, and Tenant shall restore the Demised Premises
to the condition immediately preceding the time of placement thereof. If Tenant
shall fail or refuse to remove all of Tenant's effects, personalty and equipment
from the Demised Premises upon the expiration or termination of this Lease for
any cause whatsoever or upon the Tenant being dispossessed by process of law or
otherwise, such effects, personalty and equipment shall be deemed conclusively
to be abandoned and may be appropriated, sold, stored, destroyed or otherwise
disposed of by Landlord without written notice to Tenant or any other party and
without obligation to account for same. Tenant shall pay Landlord on demand any
and all expenses incurred by Landlord in the removal of such property,
including, without limitation, the cost of repairing any damage to the Building
or Project caused by the removal of such property and storage charges (if
Landlord elects to store such property). The covenants and conditions of this
Article 33 shall survive any expiration or termination of this Lease.

34.  Notices. All notices required or permitted to be given hereunder shall be
in writing and may be delivered in person to either party or may be sent by
courier, recognized national overnight delivery service or by United States
Mail, certified, return receipt requested, postage prepaid. Any such notice
shall be deemed received by the party to whom it was sent (i) in the case of
personal delivery, recognized national overnight delivery service or courier
delivery, on the date of delivery to such party, (ii) in the case or certified
mail, the date receipt is acknowledged on the return receipt for such notice,
and (iii) if delivery is rejected or refused or the courier, overnight delivery
service or U.S. Postal Service is unable to deliver same because of changed
address of which no notice was given pursuant hereto, the first date of such
rejection, refusal or inability to deliver. All such notices shall be addressed
to Landlord or Tenant at their respective addresses set forth hereinabove or at
such other address is either party shall have theretofore given to the other by
notice as herein provided, and all such notices to Landlord shall be sent
simultaneously to both addresses set forth for Landlord's Address for notices in
Article 1(b) hereof. Tenant hereby designates and appoints as its agent to
receive notice of all dispossessory or distraint proceedings and all other
notices required under this Lease, the person in charge of the Demised Premises
at the time said notice is given or occupying the Demised Premises at said time;
and, if no person is in charge of or occupying the said Demised Premises, then
such service or notice may be made by attaching the same, in lieu of mailing, on
the main entrance to the Demised Premises.

35.  Damage or Theft of Personal property. All personal property brought into
Demised Premises by Tenant, or Tenant's employees, patients or invitees, shall
be at the risk of Tenant only, and Landlord shall not be liable for theft
thereof or any damage thereto occasioned by any act of co-tenants, occupants,
invitees or other users of the Building or any other person. Landlord shall not
at any time be liable for damage to any property in or upon the Demised Premises
which results from power surges or other deviations from the constancy of
electrical service or from gas, smoke, water, rain, ice or snow which issues or
leaks from or forms upon any part of the Building or from the pipes or plumbing
work of the same, or from any other place whatsoever.

36.  Eminent Domain

     (a)  If all or part of the Demised Premises shall be taken for any public
or quasi-public use by virtue of the exercise of the power of eminent domain or
by private purchase in lieu thereof, this Lease shall terminate as to the part
of the Demised Premises so taken or rendered untenantable as a result of such
taking, as of the date of taking, and, in the case of a partial taking, either
Landlord or Tenant



                                       20
   24

shall have the right to terminate this Lease as to the balance of the Demised
Premises by written notice to the other within thirty (30) days after such date;
provided, however, that a condition to the exercise by Tenant of such right to
terminate shall be that the portion of the Demised Premises taken shall be of
such extent and nature as substantially to handicap, impede or impair Tenant's
use of the balance of the Demised Premises. If title to so much of the Building
or Project is taken that a reasonable amount of reconstruction thereof will not
in Landlord's sole discretion result in the Building being a practical
improvement and reasonably suitable for use for the purpose for which it is
designed, then this Lease shall terminate on the date that the condemning
authority actually takes possession of the part so condemned or purchased.

     (b)  If this Lease is terminated under the provisions of this Article 36,
Rent shall be apportioned and adjusted as of the date of termination. Tenant
shall have no claim against Landlord or against the condemning authority for the
value of any leasehold estate or for the value of the unexpired Lease Term
provided that the foregoing shall not preclude any claim that Tenant may have
against the condemning authority for the unamortized cost of leasehold
improvements, to the extent the same were installed at Tenant's expense (and not
with the proceeds of the Construction Allowance), or for loss of business,
moving expenses or other consequential damages, in accordance with subparagraph
(d) below.

     (c)  If there is a partial taking of the Building or the Project and this
Lease is not thereupon terminated under the provisions of this Article 36, then
this Lease shall remain in full force and effect, and Landlord shall, within a
reasonable time thereafter, repair or reconstruct the remaining portion of the
Building or the Project to the extent necessary to make the same a complete
architectural unit to which Tenant has access; provided that in complying with
its obligations hereunder Landlord shall not be required to expend more than the
net proceeds of the condemnation award which are paid to Landlord.

     (d)  All compensation awarded or paid to Landlord upon a total or partial
taking of the Demised Premises, the Building or the Project shall belong to and
be the property of Landlord without any participation by Tenant. Nothing herein
shall be construed to preclude Tenant from prosecuting any claim directly
against the condemning authority for loss of business, for damage to, and cost
of removal of, trade fixtures, furniture and other personal property belonging
to Tenant, and for the unamortized cost of leasehold improvements to the extent
same were installed at Tenant's expense (and not with the proceeds of the
Construction Allowance), provided, however, that no such claim shall diminish or
adversely affect Landlord's award. In no event shall Tenant have or assert a
claim for the value of any unexpired term of this Lease. Subject to the
foregoing provisions of this subparagraph (d), Tenant hereby assigns to Landlord
any and all of its right, title and interest in or to any compensation awarded
or paid as a result of any such taking.

     (e)  Notwithstanding anything to the contrary contained in this Article 36,
if, during the Lease Term, the use or occupancy of any part of the Building or
the Demised Premises shall be taken or appropriated temporarily for any public
or quasi-public use under any governmental law, ordinance, or regulations, or by
right of eminent domain, this Lease shall be and remain unaffected by such
taking or appropriation, and Tenant shall continue to pay in full all Rent
payable hereunder by Tenant during the Lease Term. In the event of any such
temporary appropriation or taking, Tenant shall be entitled to receive that
portion of any award which represents compensation for the loss of use or
occupancy of the Demised Premises during the Lease Term, and Landlord shall be
entitled to receive that portion of any award which represents the cost of
restoration and compensation for the loss of use or occupancy of the Demised
Premises after the end of the Lease Term.

37.  Parties. The term "Landlord", as used in this Lease, shall include Landlord
and its assigns and successors. It is hereby covenanted and agreed by Tenant
that should Landlord's interest in the Demised



                                       21
   25

Premises cease to exist for any reason during the Lease Term, then
notwithstanding the happening of such event, this Lease nevertheless shall
remain in full force and effect, and Tenant hereby agrees to attorn to the then
owner of the Demised Premises. The term "Tenant" shall include Tenant and its
heirs, legal representatives and successors, and shall also include Tenant's
assignees and sublessees, if this Lease shall be validly assigned or the Demised
Premises be validly sublet for the balance of the Lease Term or any renewals or
extensions thereof. In addition, Landlord and Tenant covenant and agree that
Landlord's right to transfer or assign Landlord's interest in and to the Demised
Premises, or any part or parts thereof, shall be unrestricted, and that in the
event of any such transfer or assignment by Landlord which includes the Demised
Premises, Landlord's obligations to Tenant hereunder shall cease and terminate,
and Tenant shall look only and solely to Landlord's assignee or transferee for
performance thereof. "Landlord" and "Tenant" and the pronouns used with
reference thereto, include male and female, singular and plural, corporation,
partnership, company or individual, as may fit the particular parties.

38.  Liability of Tenant. Tenant hereby indemnifies Landlord from and agrees to
hold Landlord harmless against, any and all liability, loss, cost, damage or
expense, including, without limitation court costs and reasonable attorney's
fees actually incurred (without regard to statutory definitions or constraints
upon the charge or collection thereof), through all appeals, imposed on Landlord
by any person whomsoever, caused in whole or in part by any act or omission of
Tenant, or any of its employees, contractors, servants, agents, subtenants,
assignees, representatives or invitees, or otherwise occurring in connection
with any default of Tenant hereunder. The provisions of this Article 38 shall
survive any termination of this Lease.

39.  Intentionally Omitted.

40.  Force Majeure. In the event of strike, lockout, labor trouble, civil
commotion, Act of God, or any other cause beyond a party's control (collectively
"force majeure") resulting in the Landlord's inability to supply the services or
to perform the other obligations required of Landlord hereunder, this Lease
shall not terminate and Tenant's obligation to pay Rent and all other charges
and submit due and payable by Tenant shall not be affected or excused. If, as a
result of force majeure, Landlord or Tenant is delayed in performing any of its
obligations under this Lease, other than Tenant's obligation to take possession
of the Demised Premises on or before the Rental Commencement Date and to pay
Rent and all other charges and sums payable by Tenant hereunder, Landlord's and
Tenant's performance shall be excused for a period equal to such delay and
Landlord and Tenant shall not during such period be considered to be in default
under this Lease with respect to the obligation, performance of which has thus
been delayed.

41.  Landlord's Liability. Landlord shall have no personal liability with
respect to any of the provisions of this Lease. If Landlord is in default with
respect to its obligations under this Lease, Tenant shall look solely to the
equity of Landlord in and to the Building and the Land described in EXHIBIT "A"
hereto for satisfaction of Tenant's remedies, if any. It is expressly understood
and agreed that Landlord's liability under the terms of this Lease shall in no
event exceed the amount of its interest in and to said Land and Building. In no

Landlord, nor any officer, director or shareholder of Landlord or any such
partner, member or joint venturer of Landlord be personally liable with respect

conditions and covenants of this Lease, and subject to the terms and provisions

43.  INTENTIONALLY OMITTED.

44.  Hazardous Substances. Tenant hereby covenants and agrees that Tenant shall
not cause or permit any "Hazardous Substances" (as hereinafter defined) to be
generated, placed, held, stored, used, located or disposed of at the Project or
any part thereof, except for Hazardous Substances as are commonly and legally
used or stored as a consequence of using the Demised Premises for general office
and administrative purposes, but only so long as the quantities thereof do not
pose a threat to public health or to the environment or would necessitate a
"response action", as that term is defined in CERCLA (as hereinafter defined),
and so long as Tenant strictly complies or causes compliance with all applicable
governmental rules and regulations concerning the use, storage, production,
transportation and disposal of such Hazardous Substances. Promptly upon receipt
of Landlord's request, Tenant shall submit to Landlord true and correct copies
of any reports filed by Tenant with any governmental or quasi-governmental
authority regarding the generation, placement, storage, use, treatment or
disposal of Hazardous Substances on or about the Demised Premises.

For purposes of this Article 44, "Hazardous Substance" and "release" shall have
the meanings specified for said terms in CERCLA; provided however, that in the
event CERCLA is amended to broaden the meaning of any term defined thereby, such
broadened meaning shall apply subsequent to the effective date of such
amendment; and provided further, that to the extent that the laws of the State
of Alabama establish a meaning for "Hazardous Substance" or "release" which is
broader than that specified in CERCLA, such broader meaning shall I apply; and
provided further, that "Hazardous Substance" shall also be defined to include
oil, petroleum products, extremely flammable substances, explosives; and
radioactive materials, and all other elements or compounds which are contained
in the list of Hazardous Substances adopted by the United States Environmental
Protection Agency (EPA) or in any list of toxic pollutants designated by
Congress or the EPA or which are defined as hazardous, toxic, pollutant,
infectious or radioactive by any other federal, state or local statute, law,
ordinance, code, rule, regulation, order or decree regulating, relating to or
imposing liability (including, without limitation, strict liability) or
standards of conduct concerning, any hazardous, toxic or dangerous waste,
substance or material, as now or at any time hereinafter in effect (collectively
"Environmental Laws"). Tenant hereby agrees to indemnify Landlord and hold
Landlord harmless from and against any and all losses, liabilities, including
strict liability, damages, injuries, expenses, including reasonable attorneys'
fees, costs of settlement or judgment and claims of any and every kind
whatsoever paid, incurred or suffered by, or asserted against, Landlord by any
person, entity or governmental agency for, with respect to, or as a direct or
indirect result of, the presence in, or the disposal, escape, leakage, spillage,
discharge, emission or release from, the Demised Premises of any Hazardous
Substances (including, without limitation, any losses, liabilities, including
strict liability, damages, injuries, expenses, including reasonable attorneys'
fees, costs of any settlement or judgment or claims asserted or arising under
the Comprehensive Environmental Response, Compensation and Liability Act
["CERCLA"], any so-called federal, state or local "Superfund" or "Superlien"
laws or any other Environmental Law); provided, however, that the foregoing
indemnity is limited to matters arising solely from Tenant's violation of the
covenant contained in this Article 44. The obligations of Tenant under this
Article 44 shall survive any expiration or termination of this Lease.

     45.  Submission of Lease. The submission of this Lease for examination does
not constitute an offer to lease and this Lease shall be effective only upon
execution hereof by Landlord and Tenant and upon execution of any required
Guaranty Agreement annexed hereto and incorporated herein as Exhibit "H".
Notwithstanding anything contained in this Lease to the contrary, in the event
during the Tenn of this Lease (i) Tenant becomes a separate publicly traded
entity (the "Nichols TXEN Public Entity") with a net worth of at least $25
million, and (ii) Tenant has not defaulted in payment of Rent form the Rental
Commencement Date through the period ending thirty-six (36) months after the
initial public offering of



                                       23
   27

the Nichols TXEN Public Entity, and (iii) Tenant is not otherwise in default of
this Lease, then the Guaranty shall be terminated and Guarantor shall have no
further liability with respect to this Lease.

46.  Severability. If any clause or provision of this Lease is illegal, invalid
or unenforceable under present or future laws, the remainder of this Lease shall
not be affected thereby, and in lieu of each clause or provision of this Lease
which is illegal, invalid or unenforceable, there shall be added as a part of
this Lease a clause or provision as nearly identical to the said clause or
provision as may be legal, valid and enforceable.

47.  Entire Agreement. This Lease contains the entire agreement of the parties
and no representations, inducements, promises or agreements, oral or otherwise,
between the parties not embodied herein shall be of any force or effect. No
failure of Landlord to exercise any power given Landlord hereunder, or to insist
upon strict compliance by Tenant with any obligation of Tenant hereunder, and no
custom or practice of the parties at variance with the terms hereof, shall
constitute a waiver of Landlord's right to demand exact compliance with the
terms hereof. This Lease may not be altered, waived, amended or extended except
by an instrument in writing signed by Landlord and Tenant. This Lease is not in
recordable form, and Tenant agrees not to record or cause to be recorded this
Lease or any short form or memorandum thereof.

48.  Headings. The use of headings herein is solely for the convenience of
indexing the various paragraphs hereof and shall in no event be considered in
construing or interpreting any provision of this Lease.

49.  Brokers.  THE BROKER(S), AS DEFINED IN ARTICLE 1(O) ARE ENTITLED TO A
LEASING COMMISSION BY VIRTUE OF THIS LEASE, WHICH LEASING COMMISSION SHALL BE
PAID BY LANDLORD TO BROKER(S) IN ACCORDANCE WITH THE TERMS OF A SEPARATE
AGREEMENT BETWEEN LANDLORD AND BROKER(S). Each party hereto (each "Party")
represents and warrants to the other Party hereto (the "Indemnified Party") that
(except with respect to any Broker[s] identified in Article 1(o) hereinabove)
no broker, agent, commission salesperson, or other person has represented such
Party in the negotiations for and procurement of this Lease and of the Demised
Premises and that (except with respect to any Broker(s] identified in Article
l(o) hereinabove) no commissions, fees, or compensation of any kind are due and
payable in connection herewith to any broker, agent, commission salesperson, or
other person as a result of any act or agreement of such Party. Each Party
agrees to indemnify and hold the Indemnified Party harmless from all loss,
liability, damage, claim, judgment, cost or expense (including reasonable
attorneys' fees and court costs actually incurred, without regard to statutory
definitions or constraints upon the charge or collection thereof, through all
appeals) suffered or incurred by the Indemnified Party as a result of a breach
of the representation and warranty contained in the immediately preceding
sentence or as a result of the failure to pay commissions, fees, or
compensation due to any broker who represented such Party, whether or not
disclosed, or as a result of any claim for any fee, commission or similar
compensation with respect to this Lease made by any broker, agent or finder
(other than any Broker[s] identified in Article l(o) hereinabove) claiming to
have dealt with such Party, whether or not such claim is meritorious. Tenant
shall cause any agent or broker representing Tenant to execute a lien waiver to
and for the benefit of Landlord, waiving any and all lien rights with respect to
the Building and Land which such agent or broker has or might have under State
law.

50.  Governing Law. The laws of the State shall govern the validity, performance
and enforcement of this Lease.



                                       24

51.  Guaranty. As a material inducement to Landlord, without which Landlord
would not enter into this Lease, Tenant agrees to cause to be delivered to
Landlord, together with Tenant's delivery of this Lease to Landlord, a fully
executed Guaranty in the form of Exhibit "H" attached hereto and incorporated
herein by reference.

52.  Authority. If Tenant executes this Lease as a corporation, each of the
persons executing this Lease on behalf of Tenant does hereby personally
represent and warrant that Tenant is a duly incorporated or a duly qualified (if
a foreign corporation) corporation and is fully authorized and qualified to do
business in the State in which the Demised Premises are located, that the
corporation has full right and authority to enter into this Lease, and that each
person signing on behalf of the corporation is an officer of the corporation and
is authorized to sign on behalf of the corporation. If Tenant signs as a
partnership, joint venture, limited liability company, limited liability
partnership, or sole proprietorship or other business entity (each being herein
called "Entity"), each of the persons executing on behalf of Tenant does hereby
covenant and warrant that Tenant is a duly authorized and existing Entity, that
Tenant has full right and authority to enter into this Lease, that all persons
executing this Lease on behalf of the Entity are authorized to do so on behalf
of the Entity, and that such execution is fully binding upon the Entity and its
partners, joint venturers, or principal, as the case may be. Upon the request of
Landlord, Tenant shall deliver to Landlord documentation satisfactory to
Landlord evidencing Tenant's compliance with this Article, and Tenant agrees to
promptly execute all necessary and reasonable applications or documents as
reasonably requested by Landlord, required by the jurisdiction in which the
Demised Premises is located, to permit the issuance of necessary permits and
certificates for Tenant's use and occupancy of the Demised Premises.

53.  Financial Statements. Upon or before the Effective Date, and thereafter,
upon Landlord's written request therefor, but not more often than once per year,
Tenant shall promptly furnish to Landlord a financial statement with respect to
Tenant (and any guarantor of this Lease) for its most recent fiscal year
prepared in accordance with generally accepted accounting principles and
certified to be true and correct by Tenant, and such other financial information
as Landlord may reasonably request. Landlord agrees to keep confidential and not
use such financial statements and information, except in connection with the
administration or enforcement of this Lease, a proposed sale of the Building, or
the consummation or administration of loan transactions.

54.  Joint and Several Liability. If Tenant comprises more than one person,
corporation, partnership or other entity, the liability hereunder of all such
persons, corporations, partnerships or other entities shall be joint and
several.

55.  ERISA Compliance. Tenant represents to Landlord that Tenant is not an
"employee benefit plan", a "plan" or a "governmental plan" as defined below or
an entity whose assets constitute "plan assets" as defined below. The term
"employee benefit plan" means an "employee benefit plan" as defined in Section
3(3) of the Employment Retirement Income Security Act of 1974, as amended
("ERISA"), which is subject to Title I of ERISA. The term "plan" means a "plan"
as defined in Section 4975(e)(i) of the Internal Revenue Code of 1986, as
amended. The term "governmental plan" means a "governmental plan" within the
meaning of Section 3(32) of ERISA. The term "plan assets" means "plan assets" of
one or more plans within the meaning of 2a C.F.R. 2510.3-101.

56.  Delivery of Documents. If Tenant fails to execute, acknowledge or deliver
any of the documents or instruments required under Article 28 or Article 29,
same shall be deemed a material default of Tenant; however, Tenant does hereby
make, constitute and irrevocably appoint Landlord as Tenant's attorney-in-fact
and in its name, place and stead to execute, acknowledge and deliver such
documents or instruments, and Landlord shall have the right to do so without
waiving such material default of Tenant.



                                       25
   29
In addition to any other rights or remedies Landlord may have with respect to
such failure, Landlord may also charge and collect from Tenant, as Additional
Rental, an administrative fee of $50 per day with respect to each day the same
remain delinquent.

57.     Use of Name of Tenant. Tenant hereby authorizes Landlord to identify
Tenant as a tenant of the Building and to state the amount of space leased by
Tenant in advertisements and promotional materials relating to the Building.

58.     Rule Against Perpetuities. In the event Landlord has not completed
construction of the Building on or before three (3) years from the Effective
Date, this Lease shall be null and void without any further action of the
parties.

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

pursuant to this Lease shall be deemed to be strictly limited to an
acknowledgment of approval or consent by Landlord thereto and, whether or not

warranty by Landlord that the design is safe, feasible, structurally sound or
will comply with any legal or goverrunental requirements, and Tenant shall be

                                   EXHIBIT "E"

                           BUILDING STANDARD SERVICES

Landlord shall furnish the following services to Tenant during the lease Term
(the "Building Standard Services"):

       (a)    Common-use restrooms (with cold and tempered domestic water) and
toilets at locations provided for general use and as reasonably deemed by
Landlord to be in keeping with the first-class standards of the Building, and
soap, toilet tissue and paper towels or hand dryers for such common-use
restrooms.

       (b)    Subject to curtailment as required by governmental laws, rules or
mandatory regulations, central heat and air conditioning in season, at such
temperatures and in such amounts as are reasonably deemed by Landlord to be in
keeping with the first-class standards of the Building and in contemplation of
mean climate conditions. Such heating and air conditioning shall be furnished
between 8:00 a.m. and 6:00 p.m. on weekdays (from Monday through Friday,
inclusive) and between 8:00 a.m. and 1:00 p.m. on Saturdays, all exclusive of
Holidays, as defined below (the "Building Operating Hours").

       (c)    Electric lighting service for all public areas and special service
areas of the Building in the manner and to the extent reasonably deemed by
Landlord to be in keeping with the first-class standards of the Building.

       (d)    Janitor service shall be provided five (5) days per week (Monday
through Friday), exclusive of Holidays (as hereinbelow defined), in a manner
that Landlord reasonably deems to be consistent with the first-class standards
of the Building.

       (e)    Sufficient electrical capacity at the building core electrical
panels to operate (i) incandescent lights, typewriters, calculating machines,
photocopying machines, personal computers and other machines of the same low
voltage electrical consumption (120/208 volts), provided that the total rated
electrical design load for said lighting and machines of low electrical voltage
shall not exceed 2.0 watts per square foot of rentable area; and (ii) lighting
(277/480 volts), provided that the total rated electrical design load for said
lighting shall not exceed 2.0 watts per square foot of rentable area (each such
rated electrical design load to be hereinafter referred to as the "Building
Standard Rated Electrical Design Load").

              Should Tenant's total rated electrical design load exceed the
Building Standard Rated Electrical Design Load for either low or high voltage
electrical consumption, or if Tenant's electrical design requires low voltage or
high voltage circuits in excess of Tenant's share of the Building Standard
circuits, Landlord will (at Tenant's expense) install such additional circuits
and associated high voltage panels and/or additional low voltage panels with
associated transformers (which additional circuits, panels and transformers
shall be hereinafter referred to as the "Additional Electrical Equipment"). If
the Additional Electrical Equipment is installed because Tenant's low or high
voltage rated electrical design load exceeds the applicable Building Standard
Rated Electrical Design Load, then a meter shall also be added (at Tenant's
expense) to measure the electricity used through the Additional Electrical
Equipment.

                                       34

   39



              The design and installation of any Additional Electrical Equipment
(or any related meter) required by Tenant shall be subject to the prior approval
of Landlord (which approval shall not be unreasonably withheld) and the terms
and conditions of the Lease and the Rules and Regulations attached hereto. All
expenses incurred by Landlord in connection with the review and approval of any
Additional Electrical Equipment shall also be reimbursed to Landlord by Tenant.
Tenant shall also pay on demand the actual metered cost of electricity consumed
through the Additional Electrical Equipment (if applicable), plus any actual
accounting expenses incurred by Landlord in connection with the metering
thereof.

              Tenant agrees that if Tenant uses data processing or other
electronic equipment which incorporates the use of switched mode power supplies
or any other type device causing harmonic distortion on Landlord's power
distribution system, Tenant shall install filters at Tenant's cost to eliminate
the harmonic distortion. In addition, any damage to Landlord's equipment
resulting from harmonic distortion caused by Tenant's electronic equipment shall
be repaired at Tenant's expense. Total harmonic distortion shall not exceed
thirteen percent (13%).

              If any of Tenant's electrical equipment requires conditioned
air in excess of Building Standard air conditioning, the same shall be installed
by Landlord (on Tenant's behalf), and Tenant shall pay all design, installation,
metering and operating costs relating thereto.

              If Tenant requires that certain areas within Tenant's Demised
Premises must operate in excess of the normal Building Operating Hours (as
hereinabove defined), the electrical service to such areas may be separately
circuited and metered (at Tenant's expense) such that Tenant shall be billed the
costs associated with electricity consumed during hours other than Building
Operating Hours. In the event separately metering is not practicable, such
additional electrical service shall be reasonably estimated by Landlord and
charged to Tenant as additional Rent. In the event of disagreement as to the
reasonableness of such charge, the opinion of the appropriate local utility
company or an independent professional engineering firm shall prevail.

       (f)    All Building Standard fluorescent bulb and ballast replacement in
all areas and all incandescent bulb replacement in public areas, toilet and
restroom areas, and stairwells. Tenant shall be responsible for the cost and
installation expense of any special lamps and ballasts in the Demised Premises
which are not Building Standard.

       (g)    Non-exclusive passenger elevator service to the floor(s) of the
Demised Premises during Building Operating Hours (as hereinabove defined) and
one (1) cab passenger service to the floor(s) on which the Demised Premises are
located twenty-four (24) hours per day (all subject to temporary cessation for
ordinary repair and maintenance and during times when life safety systems
override normal building operating systems), with such elevator service
available upon reasonable prior notice for purposes of receiving and taking out
furniture, fixtures and equipment.

       (h)    Security services for the Building comparable as to coverage,
control and responsiveness (but not necessarily as to means for accomplishing
same) to other similarly sized first-class, multi-tenant office buildings in the
area in which the Building is located; provided, however, Landlord shall have no
responsibility to prevent, and shall not be liable to Tenant for, any liability
or loss to Tenant, its agents, employees and visitors arising out of losses due
to theft, burglary, or damage or injury to persons or property caused by persons
gaining access to the Building and/or the Demised Premises, and Tenant hereby
releases Landlord from all liability for such losses, damages or injury.

   40



              To the extent the services described above require
electricity and water supplied by public utilities, Landlord's covenants
thereunder shall only impose on Landlord the obligation to use its reasonable
efforts to cause the applicable public utilities to furnish same. Except for
deliberate and willful acts of Landlord, failure by Landlord to furnish the
services described herein, or any cessation thereof, shall not render Landlord
liable for damages to either person or property, nor be construed as an eviction
of Tenant, nor work an abatement of rent, nor relieve Tenant from fulfillment of
any covenant or agreement hereof. In addition to the foregoing, should any of
the equipment or machinery, for any cause, fail to operate, or function
properly, Tenant shall have no claim for rebate of rent or damages on account of
an interruption in service occasioned thereby or resulting therefrom; provided,
however, Landlord agrees to use reasonable efforts to promptly repair said
equipment or machinery and to restore said services during normal business
hours.

The following dates shall constitute "Holidays" as that term is used in this
Lease: New Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving
Day, Christmas, and any other holiday generally recognized as such by landlords
of office space in the metropolitan area of the Building, as determined by
Landlord in good faith. If in the case of any specific holiday mentioned in the
preceding sentence, a different day shall be observed than the respective day
mentioned, then that day which constitutes the day observed by national banks in
the Birmingham, Alabama area on account of said holiday shall constitute the
Holiday under this Lease.

notice of the change, unless the change is required by governmental authority.

25. The directory of the Building will be provided for the display of the name
and location of the tenants. Any additional name which Tenant shall desire to
place upon said directory must first be approved by Landlord, and if so
approved, a reasonable charge may be made therefor. Additional access to the
directory of the Building may be limited by the size and location thereof.

26. Landlord may waive any one or more of these Rules and Regulations for the
benefit of any particular lessee, but no such waiver by Landlord shall be

shall be subject to and in strict accordance with the terms and conditions
hereinafter set forth.

       (a) In order to exercise the Extension Option, Tenant must provide
Landlord with written notice at least eighteen months (18) prior to the
expiration of the Term hereof of its intent to so extend the term.

       (b) All of the terms, covenants, and conditions of this Lease shall
continue in full force and effect during the Extension Term of the Lease, as if
the Extension Term were part of the original Lease Term, except that the Base
Rental Rate for the Demised Premises during the Extension Term shall be the
"then current market rate", as defined in subparagraph (c) below.

       (c) The "current market rate" shall mean the Landlord's determination of
the amount per square foot of the Rentable Floor Area of the Demised Premises
that a willing, non-equity, non-renewal, non-expansion new tenant would pay and
a willing landlord would accept at arm's length for space in a comparable
building or buildings with comparable tenant improvements, in a comparable
location in the "Highway 280/I-459" submarket of Birmingham, Alabama, giving
appropriate consideration to rental rates per rentable square foot, the presence
or absence of rent escalation clauses such as operating expense and tax pass-
throughs, length of lease term, size and location of premises being leased, if
any, and other generally applicable terms and conditions of the tenancy for a
similar building or buildings; provided, that the value of any improvements made
to the Demised Premises by Tenant at Tenant's expense shall not be considered
for the purpose of valuing the current market rate of the Premises.

4.01   Option to Expand: Provided Tenant has not assigned or subleased all or
any portion of the Demised Premises, and Tenant is not in default in the
performance of or with respect to any of the terms, covenants and conditions of
the Lease beyond any applicable cure period, Tenant, at its election, shall have
the right to expand the Demised Premises in accordance with either of the
following alternatives, provided that Tenant shall deliver written notice of its
election and its choice of option to Landlord on or before October 31, 1998.

5.01   Option to Convert to Net Lease: At such time during the Rental
Term of this Lease as Tenant occupies the entire Building, Tenant may notify the
Landlord that it proposes to convert the Lease from its current "gross" lease
standard to a "net" or "modified net" standard. In such event Landlord and
Tenant agree to negotiate in good faith to convert the Lease to such a "net" or
"modified net" standard. Such conversion will include restating the Base Rental
Rate to a "net" or "modified net" form and revising the operating expense
reimbursement provisions of this Lease to specify those expenses (i) that Tenant
will pay directly, (ii) that Tenant will reimburse Landlord for, and (iii) will
be included in common area maintenance charges for the Meadow Brook South
development or for Meadow Brook Corporate Park. Upon the mutual agreement of
Landlord and Tenant on a "net" or "modified net" conversion, the Lease Agreement
shall be amended to reflect such changes.

6.01   Exterior Tenant Signage: Tenant may be permitted to display signage
graphics in one location on the exterior surface of the Building in a location
designated by Landlord. The size and style of the sign shall be subject to
approval by Landlord and the Architectural Review Committee of Meadow Brook
Corporate Park. The fabrication and installation of the sign shall be at
Tenant's sole expense.

                                       43

   48



Any signage placed on or adjacent to the Building in accordance with this
Section 7.01 must comply with all codes and requirements imposed by governing
authorities with jurisdiction over the Building. Tenant shall be responsible for
the ongoing maintenance of the sign and shall be responsible for removing the
sign upon vacating the Demised Premises in accordance with the provisions of
this Lease. Additionally, if Tenant's Demised Premises shall be reduced, for any
reason, below 50,000 square feet of Rentable Floor Area, Tenant shall be
responsible for removing the signage on the Building at Tenant's sole cost.
Tenant shall repair any damage to the Building or Land caused during the
installation, maintenance or removal of the signage as set forth above.

1.     Expansion Option 1 (Must Take Expansion): Tenant shall expand its Demised
Premises into the remaining 24,638 square feet of rentable area in the Building
no later than April 1, 2000 (hereinafter referred to as "Expansion Option 1").
Said Expansion Option 1 shall be subject to and in strict accordance with the
terms and conditions hereinafter set forth.

       (a) After Tenant has notified Landlord of its intent to exercise
Expansion Option 1, Landlord and Tenant shall promptly proceed to amend the
Lease to reflect the addition of the "Expansion Space" (as hereinafter defined)
to the Demised Premises upon Tenant's election to actually exercised its option
to expand, as described below.

       (b) Expansion Option 1 shall apply to the entire remaining rentable area
in the Building (the "Expansion Space") so that upon the Expansion Space
Commencement Date, as defined below, Tenant shall occupy the entire Building.

       (c) Rent for the Expansion Space shall commence on the date ("Expansion
Space Commencement Date") which is the earlier of (i) the date on which Tenant
occupies the Expansion Space for conduct of business or (ii) April 1, 2000.

       (d) The term for the Expansion Space shall be co-terminus with the Rental
Term of this Lease ("Expansion Term").

       (e) Subject to the provisions of this Paragraph 4.01 of Exhibit "G" of
the Lease, the provisions of Exhibit "C" of this Lease shall apply to Tenant's
build-out of the Expansion Space.

       (f) All of the terms, covenants and conditions of this Lease shall
continue in full force and effect, except that there shall be no Refurbishment
Allowance for the Expansion Space and except that the Base Rental and Tenant's
Additional Rental under the Lease shall be adjusted to reflect the addition to
the Demised Premises of the Expansion Space as of the Expansion Space
Commencement Date.

       (g) In connection with the Expansion Space, Landlord shall provide Tenant
(i) the Construction Allowance set forth in Article 1 (m) above and (ii) the
Additional Tenant Allowance set forth in paragraph 1.01 of this Exhibit "G",
each of which shall be adjusted by multiplying by a fraction, the numerator of
which shall be the number of months remaining in the Rental Term as of the
Expansion Space Commencement Date and the denominator of which shall be 120.

2.      Expansion Option 2 (Option to Expand): Provided Tenant has not assigned
or subleased all or any portion of the Demised Premises, and Tenant is not in
default in the performance of or with respect to any of the terms, covenants and
conditions of the Lease beyond any applicable cure period, Tenant shall have the
right during the first twelve (12) months following the Rental Commencement Date
to exercise an option to expand its Demised Premises into the remaining 24,638
square feet of rentable area in the Building (hereinafter referred to as
"Expansion Option 2"). Said Expansion Option 2 shall

                                       44

   49



be subject to and in strict accordance with the terms and conditions hereinafter
set forth.

       (a) If Tenant has notified Landlord of its intent to exercise Expansion
Option 2, Landlord and Tenant shall promptly proceed to amend the Lease to
reflect the addition of the Expansion Space to the Demised Premises upon
Tenant's election to actually exercise its option to expand, as described below.

       (b) Expansion Option 2 shall apply to the entire Expansion Space so that
upon the Expansion Space Commencement Date, as defined below, Tenant shall
occupy the entire rentable area of the Building.

       (c) Rent for the Expansion Space shall commence on the Expansion Space
Commencement Date, as defined in 4.01-1 above.

       (d) The term for the Expansion Space shall be co-terminus with the Rental
Term of this Lease ("Expansion Term").

       (e) Subject to the provisions of this Paragraph 4.01 of Exhibit "G" of
the Lease, the provisions of Exhibit "C" of this Lease shall apply to Tenant's
build-out of the Expansion Space.

       (f) All of the terms, covenants and conditions of this Lease shall
continue in full force and effect except that the Base Rental and Tenant's
Additional Rental under the Lease shall be adjusted to reflect the addition to
the Demised Premises of the Expansion Space as of the Expansion Space
Commencement Date.

       (g) In connection with the Expansion Space, Landlord shall provide Tenant
(i) the Construction Allowance set forth in Article 1(m), (ii) the Additional
Tenant Allowance set forth in paragraph 1.01 of this Exhibit "G", and (iii) the
Refurbishment Allowance as set forth in paragraph 2.01 of this Exhibit "G", each
of which shall be adjusted by multiplying by a fraction, the numerator of which
shall be the number of months remaining in the Rental Term as of the Expansion
Space Commencement Date and the denominator of which shall be 120.

       (h) Notwithstanding anything contained in this Lease to the contrary, if
Tenant elects Expansion Option 2, the Base Rental Rate set forth in Article 1(j)
above shall be increased to $17.75 per square foot of Rentable Floor Area of the
entire Demised Premises, including the Expansion Space, per year commencing on
the Rental Commencement Date, subject to adjustment in accordance with Article 7
above, except that the following Base Rental Rates shall be substituted for
those contained in Article 7(b):

                                 EXHIBIT "H"

               ABSOLUTE, UNCONDITIONAL AND CONTINUING GUARANTY
                       OF PAYMENT OF LEASE OBLIGATIONS



1.     FOR VALUE RECEIVED, and in consideration of and as an express
inducement, to the execution, acknowledgement and delivery of that certain:

       Lease Agreement by and between Daniel Meadow Brook South, L.L.C.
       (herein referred to as "Lessor"), and Nichols TXEN Corporation (herein
       referred to as "Lessee"), dated as of May 8, 1998.

(herein referred to as the "Lease Agreement") for the lease of that certain
tract or parcel of real property, together with the improvements located
thereon, situated and lying and being located at Meadow Brook, in the City of
Hoover, County of Shelby, State of Alabama (herein referred to as the "Leased
Premises"), the undersigned, Nichols Research Corporation, a Delaware
corporation, as Guarantor (herein referred to as "Guarantor") hereby
absolutely, unconditionally and continually guarantees to Daniel Meadow Brook
South, L.L.C., Lessor, the due, full, prompt and punctual payment when due or
at any time thereafter of:

       All rents, costs, expenses, late charges, penalties and other sums due
       and payable by Lessee under the Lease Agreement, including, without
       limitation, the repayment of the Relocation Planning Allowance, whether
       now or hereafter owed by Lessee pursuant to the Lease Agreement (herein
       referred to, separately and severally, and collectively, as the "Lease
       Obligations"),

of every kind and character, direct or indirect, absolute or contingent,
whether written, oral and/or otherwise, and whether the Lease Obligations are
from time to time reduced and thereafter increased, or entirely extinguished
and thereafter reincurred, or whether the Lease Obligations arise with or
without notice to the Guarantor.

2.     This Guaranty is, and is intended to be, an absolute, unconditional and
continuing guaranty of payment which shall not be affected by any act or thing
whatsoever except as herein provided, and which shall be independent of and in
addition to any other guaranty, endorsement or collateral held by the Lessor
with respect to the Leased Premises, the Lease Agreement and/or any or all of
the Lease Obligations.

3.     This Guaranty shall remain in full force and effect until the Lease
Obligations have been fully paid irrespective of any cancellation, expiration
or termination of this Lease Agreement and/or any change in the condition,
nature, occupancy or state of the Leased Premises.

4.     Lessor shall have the right from time to time and at any time, without
in any way affecting, diminishing, impairing, releasing and/or terminating in
any manner Lessor's rights against Guarantor's obligations hereunder and/or any
of the conditions, provisions and terms of the Lease Agreement, and/or of
Lessee's obligations thereunder, and without demand or notice, or consent of
Guarantor:

       (a)     To amend, change, and/or modify, whether by action or inaction,
any one or more of the conditions, provisions and terms of the Lease Agreement
including, but not limited to, the Lease

                                      46
   51

Obligations;

       (b) To allow, grant and/or permit, whether by action or inaction, any
extensions, indulgences and/or waives to one or more of the conditions,
provisions and terms of the Lease Agreement including, but not limited to, the
Lease Obligations;

       (c) To allow, consent to and/or permit, whether by action or inaction,
any assignment of the Lease Agreement and/or any sublease of the Leased
Premises;

       (d) To assert against Lessee any one or more of the rights or remedies
reserved to Lessor pursuant to or by virtue of the Lease Agreement or any
amendment, change or modification thereto;

       (e) To release any obligor or other guarantor of the Lease Agreement
and/or the Lease Obligations, or any part thereof, in whole or in part;

       (f) To amend, change, extend, increase, mature, modify, renew and/or
otherwise change any one or more of the conditions, provisions and/or terms of
the Lease Agreement and/or the terms and/or the time for payment of the Lease
Obligations, with or without the use of amendments, documents, instruments,
modifications or other writings;

       (g) To receive, exchange or release any collateral securing the Lease
Agreement and/or the payment of any of the Lease Obligations, or any part of any
of them;

       (h) To make any agreement extending, reducing or terminating the term of
the Lease Agreement, or otherwise affecting or altering the payment of all or
any part of the Lease Obligations, and to grant indulgences with respect to
these matters;

       (i) To exercise or refrain from exercising or waiving any right Lessor
might have pertaining to the Leased Premises and/or under the Lease Agreement;

       (j) To accept security of any kind from Lessee;

       (k) To consent to a changed or different use of the Leased Premises;

       (1) To terminate the Lease Agreement and relet the Leased Premises to a
new tenant (i) upon breach or default by Lessee under the Lease Agreement and/or
(ii) upon Lessee abandoning the Leased Premises, all as provided in the Lease
Agreement and subject to such conditions set forth therein.

Guarantor agrees that despite any of the foregoing, Guarantor is and shall
remain at all times absolutely, fully and unconditionally liable to Lessor for
payment of the Lease Obligations.

5.     Guarantor waives notice of the acceptance of this Guaranty, presentment,
protest, notice of protest and any and all demands for performance or any and
all notice of non-performance which might otherwise be a condition precedent to
the liability of Guarantor under this Guaranty. Guarantor agrees and covenants
that Lessor may proceed directly against Guarantor, without first proceeding or
making claim or exhausting any remedy against Lessee or pursuing any particular
remedy or remedies available to Lessor.

6.     Until such time as the Lease Obligations shall have been paid in full,
Guarantor, as an insider of the Lessee, waives and agrees not to assert any
claim Guaranty may now or later have against Lessee

                                       47



   52



for any payment or transfer of anything of value which Guarantor has made, or
may be obligated to make, for any reason. Guarantor agrees that Guarantor will
have no claim against Lessee and no right of recourse to or with respect to any
assets or property of Lessee until Lessor shall have fully paid all of the Lease
Obligations as and when due. Nothing herein, however, shall be deemed to
preclude any Guarantor from (i) receiving or asserting the right to receive any
payment due to Guarantor as the parent corporation of the Lessee provided such
payment does not render the Lessee unable to make any payments then or
thereafter due under the Lease Agreement, and (ii) receiving or asserting the
right to receive from the Lessee any payment made by Guarantor pursuant to this
Guaranty provided that Lessee has not been in default with respect to any
obligation for payment under the Lease Agreement for a period of six (6)
consecutive months and such payment will not render the Lessee unable to make
payments then or thereafter due under the Lease Agreement. Guarantor agrees that
this paragraph is intended to benefit Lessee and is relied upon by Lessor. (As
used in this paragraph, the terms "insider" and "claim" are defined and shall
have the same meaning as set forth in the United States Bankruptcy Code, 11
U.S.C, ss.101 et. seq.)

7.     Subrogation rights or any other rights of any kind of Guarantor, in its
capacity as Guarantor, against Lessee, if any, shall not become available to
Guarantor until all of the Lease Obligations are fully paid.

8.     Guarantor agrees that upon the occurrence of any one or more of the
following events:


       (a) Lessee's default in payment of any of the Lease Obligations;

       (b) Lessee shall become insolvent or shall be adjudicated a bankrupt;

       (c) Lessee shall file a petition for reorganization, arrangement or
similar relief under any present or future provision of the Bankruptcy Code;

       (d) A petition for reorganization, arrangement or similar relief under
any present or future provision of the Bankruptcy Code filed by creditors of
Lessee shall be approved by a court;

       (e) Lessee shall seek a judicial readjustment of the rights of Lessee's
creditors under any present or future federal or state law; or

       (f) A receiver of all or any part of Lessee's property and asserts is
appointed by any state or federal court, and in any such proceeding the Lease
Agreement shall be terminated or rejected or the Lease Obligations of Lessee
under the Lease Agreement shall be modified.

then Guarantor will pay to Lessor:

       (i) Immediately upon the occurrence of one or more such events, an amount
equal to all Lease Obligations accrued to the date of such event(s), plus

       (ii) Subsequent to the occurrence of one or more of such events, the
Lease Obligations due under the Lease Agreement for the balance of the term
thereof as and when such payments become due reduced by any payments received by
Lessor as a result of the reletting of the Leased Premises.

9.     Neither Guarantor's obligations to make payment in accordance with the
terms of this Guaranty, nor any remedy for the enforcement of this Guaranty,
shall be impaired, modified, changed, released or limited in any manner
whatsoever by any impairment, modification, change, release or limitation of the

                                       48

   53



liability of Lessee or Lessee's estate in bankruptcy or of any remedy for the
enforcement resulting from the operation of any present or future provision of
the federal Bankruptcy Code or from the decision of any court.

10.    Guarantor shall pay all reasonable costs and expenses of Lessor in
attempting to collect and actually collecting the indebtedness due from Lessee,
and in attempting to enforce and actually enforcing performance of the
Obligations, and in enforcing the Lease Agreement and/or this Guaranty,
including, but not limited to, reasonable attorney's fees and court costs.

11.    This Guaranty may not be canceled by Guarantor, this Guaranty shall
remain continually in full force and effect until the Lease Obligations have
been fully paid irrespective of any cancellation, expiration or termination of
the Lease Agreement and/or any change in the condition, nature, occupancy or
state of the Leased Premises.

12.    All notices and/or demands given or made pursuant to this Agreement shall
be given or made either by (a) United States First Class Certified Mail, Return
Receipt Requested, Postage Prepaid, or (b) by expedited courier service (such as
Federal Express) and shall be deemed given when addressed to and received by (i)
Lessor at the address specified in the Lease Agreement and (ii) Guarantor at
the address set forth under its signature on this Agreement.

13.    The word "Lessor" wherever used in this Guaranty and the Lease Agreement
shall include successors and assigns of Lessor as if each time fully expressed.
The word "Guarantor" wherever used in this Guaranty shall include the respective
successors of the Guarantor as if each time fully expressed.

14.    If, for any reason, any provision of this Guaranty should be declared
null and void or unconstitutional or unenforceable by a final, non-appealable
order of any court of competent jurisdiction, the remainder of this Guaranty
shall not be impaired and shall remain in full force and effect.

15.    As this Guaranty has been drafted jointly by Lessor and by Guarantor,
after extensive consultation with their respective counsel, no presumption
against the draftsman of this Guaranty shall be indulged in the construction
and/or interpretation hereof.

16.    This Guaranty is to be construed, controlled, enforced, governed, and
interpreted by the laws of the State of Alabama.

17.    Each and every provision of this Guaranty inures and shall inure to the
benefit of Lessor's successors, assigns, grantees, and successors in interest.

18.    Guarantor's successors and assigns shall be fully bound by this Guaranty
and all provisions hereof, just as Guarantor is bound.

19.    This Guaranty embodies the entire agreement and understanding of Lessor
and Guarantor as to the matters set forth herein, and mergers herein all
agreements, covenants, representations, statements and understandings heretofore
made by and between Lessor and Guarantor as to such matters, whether written,
oral or both. Any agreements, covenants, representations, statements or
understandings as to such matters not incorporated herein, are, and shall be,
null and void and of no force and effect.

20.    Neither this Guaranty nor any condition, provision or term hereof, shall
be amended, changed, or modified in any respect, nor may any estoppel, novation
or waiver regarding the same be effectuated, without Lessor and Guarantor first
executing a writing, in equal dignity to this Guaranty, embodying their

                                       49
   54

complete and full agreement and understanding as to such amendment, change,
modification, estoppel, novation, or waiver.


21.  Guarantor acknowledges, agrees, covenants, represents and warrants to
Lessor that the Guarantor is the parent corporation of Lessee, and that it is
of material advantage and benefit to Guarantor for Lessor and Lessee to enter
into the Lease Agreement.


22.  This Guaranty is executed, acknowledged and delivered by Guarantor prior
to, or simultaneously with, the execution, acknowledgement and delivery of the
Lease Agreement by Lessor and Lessee, and to expressly induce Lessor to
execute, acknowledge and deliver the Lease Agreement, well knowing and
understanding that Lessor would not do so without this Guaranty being in full
force and effect.


IN WITNESS WHEREOF, Guarantor has caused these presents to be executed as of
the 8 day of May, 1998.


             CAUTION--IT IS IMPORTANT THAT YOU THOROUGHLY READ THE

                       FIRST AMENDMENT TO LEASE AGREEMENT
                           TENANT EXPANSION AGREEMENT

         THIS First Amendment to Lease ("First Amendment") made and entered into
as of this 9th day of December, 1998, by and between Meadow Brook South 2500,
L.L.C. ("Landlord"), and Nichols TXEN Corporation ("Tenant").

                                   WITNESSETH

           WHEREAS, Landlord's predecessor in interest, Daniel Meadow Brook
 South, L.L.C., has heretofore entered into that certain lease (the "Lease")
 dated the 8th day of May, 1998 for premises (the "Demised Premises") initially
 containing approximately 73,915 square feet of Rentable Floor Area, in the
 building known as 2500 Corporate Drive (the "Building") the address of which is
 2500 Corporate Drive.

  WHEREAS, Tenant has requested (a) that additional space in the Building
 consisting of approximately 23,908 square feet of Rentable Floor Area shown on
 Exhibit "B" attached hereto and incorporated herein (the "Expansion Space") be
 added to the Demised Premises, so that Tenant will occupy the entire Rentable
 Floor Area of the Building, and (b) that the location of the Demised Premises
 and Expansion Space as defined in the Lease be altered.

          NOW, THEREFORE, in consideration of the mutual covenants and
 agreements herein contained, and other good and valuable consideration, the
 parties do hereby agree as follows. Capitalized terms used herein not otherwise
 defined shall have the same meaning as set forth in the Lease.

          1. RELOCATION OF DEMISED PREMISES AND EXPANSION SPACE. The Demised
 Premises shall be relocated as shown on Exhibit "A-1 " and "A-2" attached
 hereto. The Expansion Space shall be relocated as shown on Exhibit "B" attached
 hereto.

          2. ADJUSTMENT OF RENTABLE FLOOR AREA. The parties hereto acknowledge
 and agree that the Rentable Floor Areas of the Building and the Demised
 Premises have changed. Accordingly, the Rentable Floor Area of the Demised
 Premises set forth in Article 1 (g) of the Lease shall be 74,308 square feet
 and the Rentable Floor Area of the Building set forth in Article 1 (h) of the
 Lease shall be 98,216 square feet.

          3. EXPANSION. Commencing on the earlier of (a) April 1, 2000 or (b)
 the date on which the Tenant occupies the Expansion Space and operates
 therefrom (the "Expansion Space Commencement Date"), the Expansion Space shall
 be added to and become a part of the Demised Premises, subject to all of the
 terms and conditions of the Lease currently in effect, except as expressly
 modified herein. On the Expansion Space Commencement Date set forth above, the
 Demised Premises, including the Expansion Space, shall be increased to 98,216
 square feet of Rentable Floor Area. The Expansion Space Commencement Date shall
 be subject to adjustment as described in Paragraph 5, below.

          4. RENTALS AND OTHER CHARGES. Effective as of the Expansion Space
 Commencement Date, the Rent under the Lease, as defined in Article 5 (a) of the
 Lease, for the Demised Premises shall be adjusted to reflect the addition of
 the Expansion Space to the Demised Premises.

          The Rent respecting the Expansion Space is sometimes herein called the
"Expansion Space Rent".

          5. Possession. Tenant agrees to accept the Expansion Space without any
 agreements, representations, understanding or obligations on the part of
 Landlord to perform any alterations, repairs



   57



 or improvements except as expressly provided for in the Work Letter, attached
 to the Lease as Exhibit C. Tenant covenants and agrees to cause the plans and
 specifications (as set forth in paragraph 1 (b) of Exhibit C of the Lease) for
 the Expansion Space to be delivered to Landlord upon the earlier to occur of
 the date which is (a) 150 days prior to the anticipated Expansion Space
 Commencement Date, or (b) November 1, 1999. Any construction, alterations or
 improvements made to the Expansion Space by Tenant shall be subject to
 Landlord's prior written approval including without limitation, approval of the
 plans, specifications, contractors and subcontractors therefor, and all
 applicable terms and conditions of the Lease relating to construction,
 alterations or improvements of the Demised Premises, and such other reasonable
 requirements or conditions as Landlord may impose. During any period that
 Tenant shall be permitted to enter the Expansion Space prior to the Expansion
 Space Commencement Date other than to occupy the same in the normal conduct of
 business (e.g., to perform alterations or improvements), Tenant shall comply
 with all terms and provisions of the Lease, except those provisions requiring
 payment of Expansion Space Rent. If Tenant shall enter the Expansion Space
 prior to the Expansion Space Commencement Date for the purpose of occupying the
 same in the normal conduct of business, Expansion Space Rent shall commence on
 such date.

          The Expansion Space Commencement Date shall be delayed and Expansion
 Space Rent shall be abated to the extent that Landlord fails: (a) to
 substantially complete any improvements to the Expansion Space required to be
 performed by Landlord under Exhibit C of the Lease in connection herewith, or
 (b) to deliver possession of the Expansion Space for any other reason, except
 to the extent that Tenant, its contractors, agents, or employees in any way
 contribute to either such failures. Any such delay in the Expansion Space
 Commencement Date shall not subject Landlord to any liability for any loss or
 damage resulting therefrom, and Tenant's sole remedy with respect thereto shall
 be the abatement of Expansion Space Rent.

          6. TENANT ALLOWANCES. Landlord shall provide Tenant a Construction
 Allowance for the Expansion Space equal to $15.00 per rentable square foot of
 the Expansion Space multiplied by a fraction, the numerator of which shall be
 the number of months remaining in the initial Rental Term as of the Expansion
 Space Commencement Date and the denominator of which shall be 120.
 Additionally, Landlord shall provide Tenant a Moving Allowance for the
 Expansion Space equal to $1.50 per rentable square foot of the Expansion Space
 multiplied by a fraction, the numerator of which shall be the number of months
 remaining in the initial Rental Term as of the Expansion Space Commencement
 Date and the denominator of which shall be 120. The Moving Allowance shall be
 paid to Tenant within thirty (30) days of the Expansion Space Commencement Date
 and upon receipt by Landlord of copies of the invoices for the costs associated
 with Tenant's move into the Expansion Space.

          7. WHOLE AGREEMENT. This First Amendment, together with its
 attachments and Exhibits, sets forth the entire agreement between the parties
 with respect to the matters set forth herein. Other than the Lease, there have
 been no additional oral or written representations or agreements nor shall any
 agreement between the parties be valid unless it is set forth in writing and
 duly signed by each party. As amended herein, the Lease between the parties
 shall remain in full force and effect. In case of any inconsistency between the
 provisions of the Lease and this First Amendment, the provisions of this First
 Amendment shall govern and control.

          8. GUARANTORS. This First Amendment shall be of no force or effect
 unless and until accepted by any guarantors of the Lease, who by signing below
 agree that their guarantee shall apply to the Lease as amended herein.



   58



IN WITNESS WHEREOF, the Landlord and Tenant have duly executed this First
Amendment as of the day and year first above written.

         1. Section 1.01 A of Exhibit G of the Lease shall be modified in

                  at Inverness Center.
         b)       The last paragraph of Section 1.01 A of Exhibit G of the
