causes beyond the reasonable control of Landlord.  Subject to possible rent
abatement as may be provided pursuant to the conditions described in ARTICLE

never be deemed a disturbance of Tenant's use and possession of the Leased
Premises, or render Landlord liable to Tenant for damages by abatement of rent
or otherwise, or relieve Tenant from performance of Tenant's obligations under
this Lease.  However, Landlord shall use its best efforts to cause the Building

future alterations of the Leased Premises by Tenant, comply with the provisions
of all applicable recorded covenants, conditions and restrictions and all
applicable building, zoning, fire and other governmental laws, ordinances,
regulations or rules as the same are applicable to the Leased Premises.

covenants, conditions and restrictions affecting the Leased Premises.

      c.      Nuisances or Waste:  Not do or permit anything to be done in or
about the Leased Premises, or bring or keep anything in the Leased Premises
that may increase Landlord's fire and extended coverage insurance premium,

menace or other disturbance to tenants of adjoining premises or anyone else, or
use or store any toxic chemicals, wastes, elements or substances in the Leased
Premises.

      d.      Alterations and Improvements:  Make no substantial alterations or
improvements to the Leased Premises without the prior written approval of
Landlord not to be unreasonably withheld.  Any such alterations or improvements
by Tenant shall be done in a good and workmanlike manner, at Tenant's expense,
by a licensed contractor approved by Landlord and in conformity with plans and
specifications approved by Landlord.

      e.      Liens:  Keep the Leased Premises, the Building and the Project
free from liens arising out of any work performed, materials furnished or
obligations incurred by or for Tenant.  If, at any time, a lien or encumbrance
is filed against the Leased Premises, the Building or the Project as a result
of Tenant's work, materials or obligations, Tenant shall promptly discharge
such lien or encumbrance.  If such lien or encumbrance has not been removed
within sixty (60) days from the date it is filed, Tenant agrees to deposit with
Landlord cash or a bond in an amount equal to 150% of the amount of the lien,
to be held by Landlord as security for the lien being discharged, however, if
Landlord is, at the time of the filing of the lien, involved in any
negotiations that require a clear title to the property, Tenant agrees to
immediately deposit with Landlord cash or bond as provided above.

      f.      Rules and Regulations:  Observe, perform and abide by all the
reasonable rules and regulations promulgated by Landlord from time to time as
said rules and regulations are applied equally to other tenants of the

      g.      Signage:  Obtain the prior approval of the Landlord and
Landlord's mortgagee, if any, before placing any sign or symbol in doors or
windows or elsewhere in or about the Leased Premises, or upon any other part of
the Building, or Project including building directories.  Any signs or symbols
which have been placed without Landlord's approval may be removed by Landlord.
Upon expiration or termination of this Lease, all signs installed by Tenant
shall be removed and any damage resulting therefrom shall be promptly repaired,
or such removal and repair may be done by Landlord and the cost charged to
Tenant as Rent.  Tenant shall be entitled to customary recognition in the
Building's directory and suite signage, and to recognition on the exterior
mounted building signage.  The signage tenant directory shall be installed by
Landlord prior to commencement of the Lease Term.

comprehensive general liability insurance and fire and extended casualty

and maintain during the Lease Term comprehensive general liability insurance
with respect to the Leased Premises and Tenant's activities in the Leased
Premises and in the Building and the Project, providing bodily injury, broad

      a.      $1,000,000.00 with respect to bodily injury or death to any one

100% of their actual replacement cost; and

      e.      Workers' compensation insurance in at least the statutory
amounts.

      Nothing in this paragraph 6.2 shall prevent Tenant from either providing
a self-insured retention of $5,000,000.00 per occurrence covering the risks and
exposures set forth in Sections a. through c. hereof or from obtaining
insurance of the kind and in the amounts provided for under this paragraph
under a blanket insurance policy covering other properties as well as the
Leased Premises, provided, however, that any such policy of blanket insurance
(i) shall specify the amounts of the total insurance allocated to the Leased
Premises, which amounts shall not be less than the amounts required by sections
a. through c. hereof., and (ii) such amounts so specified shall be sufficient
to prevent any one of the assureds from becoming a coinsurer within the terms
of the applicable policy, and (iii) shall,





                                     -25-
<PAGE>   7

as to the Leased Premises, otherwise comply as to endorsements and coverage
with the provisions of this paragraph.

      Tenant's insurance shall be issued by an insurer reasonably  acceptable
to and approved by Landlord.  Landlord and Landlord's mortgagee, if any, shall
be named as "additional insureds" under Tenant's insurance, and such Tenant's
insurance shall be primary and non-contributing with Landlord's insurance.
Tenant's insurance policies shall contain endorsements requiring thirty (30)
days' notice to Landlord and Landlord's mortgagee, if any, prior to any
cancellation, lapse or nonrenewal or any reduction in amount of coverage.

      Tenant shall deliver to Landlord as a condition to its taking occupancy
of the Leased Premises a certificate or certificates evidencing such insurance.

6.3   REPAIRS:  Subject to Landlord's Maintenance Services obligations as
described in ARTICLE 5.1b and in Schedule 4, Tenant agrees to maintain the
interior of the Leased Premises in a neat, clean and sanitary condition.  If
Tenant fails to maintain or keep the Leased Premises in good repair and such
failure continues for five (5) business days after written notice from Landlord
or if such failure results in a nuisance or health or safety risk, Landlord may
perform any such required maintenance and repairs and the cost thereof shall be
payable by Tenant as Rent within thirty (30) days of receipt of an invoice from
Landlord.  Tenant shall also pay to Landlord the costs of any repair to the
Building or Project necessitated by any act or neglect of Tenant.

6.4   ASSIGNMENT AND SUBLETTING:  Tenant shall not assign, mortgage, pledge or
encumber this Lease, or permit all or any part of the Leased Premises to be
subleased to another, without the prior written consent of Landlord.  Landlord
agrees that it will not unreasonably withhold its consent to Tenant's assigning
this Lease or subletting the Leased Premises.  Tenant may, without the
Landlord's consent, assign this Lease to any parent, affiliate and/or any
successor, provided Tenant remains at all times primarily liable for all
obligations under the Lease.

     Except as it relates to Tenant's assignment or subletting as noted above
to the parent, affiliate or successor, Tenant hereby agrees that Landlord shall
be deemed to be reasonable in withholding its consent if Tenant is in default
under any of the substantial terms, covenants, conditions, provisions and
agreements of this Lease past any period of cure provided for herein at the
time of request for consent or on the effective date of such subletting or
assigning, or if the proposed subtenant or assignee is, in Landlord's good
faith judgment, incompatible with other tenants in the Building, or seeks to
use the Leased Premises for a use not consistent with other uses in the
Building.  Upon the Landlord's request, Tenant shall submit to Landlord the
name of a proposed assignee or subtenant, the terms of the proposed assignment
or subletting, the nature of the proposed





                                     -26-
<PAGE>   8

subtenant's business and such information as to the assignee's or subtenant's
general reputation as Landlord may reasonably require.

     No subletting or assignment, even with the consent of the Landlord, shall
relieve Tenant of its obligation to pay the Rent and to perform all of the
other obligations to be performed by Tenant hereunder.  The acceptance of rent
by Landlord from any other person shall not be deemed to be a waiver by
Landlord of any provision of this Lease or to be a consent to any assignment,
subletting or other transfer.  Consent to one assignment, subletting or other
transfer shall not be deemed to constitute consent to any subsequent
assignment, subletting or other transfer.

6.5   ESTOPPEL CERTIFICATE:  From time to time and within thirty (30) days
after Tenant's receipt of a written request by Landlord, Tenant shall execute
and deliver a certificate supplied by Landlord to any proposed lender or
purchaser, or to Landlord,  certifying with any appropriate exceptions, (i)
that this Lease is in full force and effect without modification, (ii) the
amount, if any, of Prepaid Rent and Deposit paid by Tenant to Landlord, (iii)
the nature and kind of concessions, rental or otherwise, if any, which Tenant
has received or is entitled to receive, (iv) that Landlord has performed all of
its obligations due to be performed under this Lease and that there are no
defenses, counterclaims, deductions or offsets outstanding or other excuses for
Tenant's performance under this Lease, or any exceptions to same, and (v) any
other fact reasonably requested by Landlord or such proposed lender or
purchaser.

6.6   BROKERAGE COMMISSIONS:  Tenant represents to the Landlord that no broker
or agent represented Tenant other than the Tenant's broker, Cushman & Wakefield
of Michigan, Inc., and Tenant agrees to defend and indemnify Landlord against
any loss, expense or liability incurred by Landlord as a result of a claim by
any other broker or finder with regard to its representation of Tenant in
connection with this Lease or its negotiation.  Landlord agrees to defend and
indemnify Tenant against any loss, expense or liability incurred by Tenant as a
result of a claim by any other broker or finder in connection with this Lease
or its negotiation.

                           LANDLORD'S RESERVED RIGHTS

7.1   ADDITIONAL RIGHTS RESERVED TO LANDLORD:  Without notice and without
liability to Tenant or without effecting an eviction or disturbance of Tenant's
use or possession, Landlord shall have the right to (i) grant utility easements
or other easements in, or replat, subdivide or make other changes in the legal
status of the land underlying the Building or the Project as Landlord shall
deem appropriate in its sole discretion, provided such changes do not
substantially interfere with Tenant's use of the Leased Premises for the
Permitted Purpose; (ii) enter the Leased Premises at reasonable times and after
reasonable notice to the Tenant (twenty-four (24)





                                     -27-

hours' notice required), and at any time in the event of an emergency to
inspect or repair the Leased Premises or the Building and to perform any acts
related to the safety, protection, reletting, sale or improvement of the Leased
Premises or the Building; (iii) change the name or street address of the
Building; (iv) install and maintain signs on and in the Building, subject to
Tenant's right to review and approve structural changes to be made to exterior
wall-mounted building sign; and (v) make such reasonable rules and regulations
as, in the sole judgment of Landlord, may be needed from time to time for the
safety of the tenants, the care and cleanliness of the Leased Premises, the
Building and the preservation of good order therein, which rules and
regulations shall be applied equally to all tenants of the Building.


                                 ARTICLE EIGHT
                          CASUALTY AND UNTENANTABILITY

8.1   CASUALTY AND UNTENANTABILITY:  If the Building is made substantially
untenantable or if Tenant's use and occupancy of the Leased Premises are
substantially interfered with due to damage to the common areas of the Building
or the Leased Premises are made wholly or partially untenantable by fire or
other casualty, (i) Landlord may, by notice to Tenant within sixty (60) days
after the damage, terminate this Lease, or (ii) Tenant may, by notice to
Landlord within sixty (60) days after the damage, terminate this Lease,
provided, however, that Landlord shall be provided a reasonable opportunity
within such sixty-day period to restore the Leased Premises to the conditions
specified in Schedule 1 and Tenant's working drawings.  Such termination shall
become effective as of the date of such casualty.

      If the Leased Premises are made partially or wholly untenantable by fire
or other casualty and this Lease is not terminated as provided above, Landlord
shall restore within 150 days of the date of such casualty the Leased Premises
to the condition specified in Schedule 1 and Tenant's working drawings.

      If this Lease is not terminated as provided above, and Landlord fails
within 150 days from the date of such casualty to restore the damaged common
areas thereby eliminating substantial interference with Tenant's use and
occupancy of the Leased Premises, or fails to restore the Leased Premises to
the condition specified in Schedule 1 and Tenant's working drawings, Tenant may
terminate this Lease as of the end of such 150-day period, such termination
being effective as of the date of such casualty.

      In the event of termination of this Lease pursuant to this ARTICLE EIGHT,
Rent shall be prorated on a per diem basis and paid to the date of the
casualty, unless the Leased Premises shall be tenantable, in which case Rent
shall be payable to the date of the lease termination.  If the Leased Premises
are untenantable and this Lease is not terminated, Rent and Tenant's other
obligations hereunder shall abate on a per diem basis from the date of the
casualty until the Leased





                                     -28-
<PAGE>   10

Premises are ready for occupancy by Tenant.  If part of the Leased Premises are
untenantable, Rent and Tenant's other obligations hereunder shall be prorated
on a per diem basis and apportioned in accordance with the part of the Leased
Premises which is usable by Tenant until the damaged part is ready for Tenant's
occupancy.

                                  ARTICLE NINE
                                  CONDEMNATION

9.1   CONDEMNATION:  If all or any part of the Leased Premises shall be taken
under power of eminent domain or sold under imminent threat to any public
authority or private entity having such power, this Lease shall terminate as to
the part of the Leased Premises so taken or sold, effective as of the date
title transfers or possession is required to be delivered to such authority,
whichever occurs earlier.  In such event, Base Rent shall abate in the ratio
that the portion of Tenant's Square Footage taken or sold bears to Tenant's
Square Footage.  If a partial taking or sale of the Leased Premises, the
Building or the Project (i) substantially reduces Tenant's Square Footage
resulting in a substantial inability of Tenant to use the Leased Premises for
the Permitted Purpose, or (ii) renders the Building or the Project commercially
unviable to Landlord in Landlord's sole opinion, either Tenant in the case of
(i), or Landlord in the case of (ii), may terminate this Lease by notice to the
other party within thirty (30) days after the terminating party receives
written notice of the portion to be taken or sold.  Such termination shall be
effective 180 days after notice thereof, or when the portion is taken or sold,
whichever is sooner.  All condemnation awards and similar payments shall be
paid and belong to Landlord, except any amounts awarded or paid specifically to
Tenant for removal and reinstallation of Tenant's trade fixtures, personal
property, Tenant's moving costs, or other amounts to which Tenant may be
entitled as long as they do not prejudice Landlord or reduce Landlord's award.

party or its respective property, which occurs in or about the Leased Premises,

policies of insurance obtained by either of them in connection with the Leased
Premises shall contain appropriate waiver of subrogation clauses.

                                  TERMINATION

12.1  SURRENDER OF LEASED PREMISES:  On expiration of this Lease, if no Event
of Default exists, Tenant shall surrender the Leased Premises in the same
condition as when the Lease Term commenced, ordinary wear and tear and casualty
damage excepted.  Except for furnishings, trade fixtures and other personal
property installed at Tenant's expense, all alterations, additions or
improvements, whether temporary or permanent in character, made in or upon the
Leased Premises, either by Landlord or Tenant, shall be Landlord's property and
at the expiration or earlier termination of the term shall remain on the Leased
Premises without compensation to Tenant, except if requested by Landlord at the
time they are made, Tenant, at its expense and without delay, shall remove any
alterations, additions or improvements made to the Leased Premises by Tenant
designated by Landlord to be removed, and repair any damage to the Leased
Premises or the Building caused by such removal, provided, however, that Tenant
shall not be required to remove improvements to the Leased Premises which have
previously been approved by Landlord.  If Tenant fails to repair the Leased
Premises, Landlord may complete such repairs and Tenant shall reimburse
Landlord for such repair and restoration.  Landlord shall have the option to
require Tenant to remove all its personal property.  If Tenant fails to remove
such property as required under this Lease, Landlord may dispose of such
property in its sole discretion without any liability to Tenant, and further
may charge the reasonable cost of any such disposition to Tenant.

12.2  HOLD OVER TENANCY:  If Tenant shall hold over after the Lease expiration
Date, Tenant may be deemed, at Landlord's option, to occupy the Leased Premises
as a tenant from month to month, which tenancy may be terminated by one month's
written notice.  During such tenancy, Tenant agrees to pay to Landlord, monthly
in advance, an amount equal to 150% of all Rent which would become due (based
on Base Rent payable for the last month of the Lease Term, together with all
other amounts payable by Tenant to Landlord under this Lease), and to be bound
by all of the terms, covenants and conditions herein specified.  If Landlord
relets the Leased Premises or any portion thereof to a new tenant and the term
of such new lease commences during the period for which Tenant holds over,
Landlord shall be entitled to recover from Tenant all reasonable costs and
expenses, attorney's fees, damages or loss of profits incurred by Landlord as a
result of Tenant's failure to deliver possession of the Leased Premises to
Landlord when required under this Lease.

                                UTILITY SERVICES


   The Landlord shall provide, as part of Operating Costs, except as otherwise
provided, the following services:

1.    Air conditioning and heat for normal general office purposes only, to
provide in Landlord's judgment consistent with other comparable Class A
buildings, comfortable occupancy Monday through Friday from 7:00 a.m. to 6:00

the right to charge for such services at the hourly rate of $55.00.  The charge
shall be payable as additional rental.  Should Tenant fail to make payment
within thirty (30) days after demand for same, such excess charge constitutes a
breach of the obligation to pay rent under this Lease and shall entitle

Building supply (at the prevailing temperature) through fixtures installed by
Landlord, (or by Tenant with Landlord's written consent).

               21333 Haggerty Road Office Building

Gentlemen:

   You (referred to as "Tenant"), and we (referred to as "Landlord") are
executing, simultaneous with this work letter agreement, a written lease (the
"Lease") pertaining to the space referred to above (the "Leased Premises").
This work letter agreement is attached to the Lease as Schedule 6 and made a
part of the Lease.

   To induce Tenant and Landlord, each, to enter into the Lease (which is
hereby incorporated by reference to the extent that the provisions of this work
letter agreement may apply thereto) and in consideration of the mutual
covenants hereinafter contained, Landlord and Tenant mutually agree as follows:

   1.    Definitions.  The terms defined in this paragraph, for purposes of
this work letter agreement, shall have the meanings specified herein, and, in
addition to the terms defined herein, terms defined in the Lease shall, for the
purposes of this work letter agreement, have the meanings specified therein.

    1.01  "Base Tenant Improvements" means the Building Standard items which
    are supplied, installed and finished by Landlord and such other items shown
    on the Construction Documents, according to Building Standard specifications
    and the Construction Documents and which shall be paid for by Landlord as
    provided for in paragraph 2.01 below.  Landlord agrees to provide up to a
    maximum of $18.25 per usable square foot of leased area toward the cost of
    Base Tenant Improvements.  The cost of the first $15.25 per square foot of
    construction costs have been incorporated into the base rent shown on
    Schedule 8 of the Lease.  The remaining $3.00 of construction costs, if
    required, shall be provided by Landlord and the lease rental rate schedule
    shall be 
     




                                     -50-
<PAGE>   32

    amended to reflect this additional expenditure in accordance with the
    "Additional Rent" paragraph of Schedule 8.

    1.02  "Building Standard" means the quantity and quality of materials,
    finishing and workmanship specified by Landlord for the Building.

    1.03  "Construction Documents" means Exhibit 1 which is attached hereto     
    and made a part hereof, and have been approved.

    1.04  "Extraordinary Tenant Improvements" means any work Tenant requests
    Landlord to do in connection with the Leased Premises, other than Base      
    Tenant Improvements, after the Construction Documents have been approved
    and signed by both Landlord and Tenant.  All construction costs in
    excess of $18.25 per usable square foot shall be deemed as Extraordinary
    Tenant Improvements.

    1.05  "Leasehold Improvements" means the aggregate of Base Tenant
    Improvements and Extraordinary Tenant Improvements.
        
    1.06 "Substantial Completion" means that the Leasehold Improvements have
    been substantially completed according to the Construction Documents, except
    for items which will not materially affect the use of the Leased Premises or
    which customarily are deemed to be "punchlist work," and Landlord has
    obtained either a temporary or final certificate of occupancy for the Leased
    Premises.

   2.    Construction Documents; Payments.

    2.01  The parties have approved and executed Construction Documents for     
    the Leased Premises, a copy of which is attached hereto as Exhibit 1.
    Landlord shall be solely responsible at Landlord's cost to buildout the Base
    Tenant Improvements.  Tenant shall be solely responsible at Tenant's expense
    for any Extraordinary Tenant Improvements.

   3.    Leasehold Improvements.

    3.01  The following provisions shall apply to the construction of the
    Leasehold Improvements:

         (a)  All work involved in the completion of the Leasehold Improvements
         shall be carried out by Landlord and its agents and contractors under
         the sole direction of Landlord.  Tenant shall cooperate with Landlord
         and its agents and contractors to promote the efficient and
         expeditious completion of the Leasehold Improvements; and

         (b)  Landlord agrees to construct the Leasehold Improvements in
         accordance with the Construction Documents, provided Tenant has
         complied with all the applicable provisions of this work letter
         agreement and the Lease.





                                     -51-
<PAGE>   33

   3.02  If there are any changes in the Leasehold Improvements requested by,
   or on behalf of, Tenant from the work as reflected in the approved
   Construction Documents, each such change must receive the prior written
   approval of Landlord, and Tenant shall bear the cost of all such changes.

   3.03  Landlord shall have no obligation to commence construction of any work
   in the Leased Premises until Landlord has submitted and Tenant has approved
   and signed the Construction Documents.

   3.04  Tenant shall be responsible for the installation of all security,
   voice, data and telephone cabling and any costs in excess of the Estimate
   provided in paragraph 2.01 above.

   In the event that Landlord shall fail, for any cause, to complete the
   Leasehold Improvements on or before November 1, 1996, Landlord shall not be
   subject to any liability therefor nor shall such failure affect the validity
   of the Lease and Tenant's obligations thereunder.

  4.    Lease Commencement Date.

   4.01 Landlord shall notify Tenant when Substantial Completion has been       
   achieved, and thereafter the Lease Commencement Date shall be established as
   set forth in the Lease.  Notwithstanding anything to the contrary contained
   in the Lease or this work letter agreement, the Lease Commencement Date shall
   not be extended for any delay in Substantial Completion to the extent that
   such delay is caused in whole or in part by any act or omission attributable
   to Tenant, including without limitation:

         (a) Tenant's request for any Extraordinary Tenant Improvements;

         (b) Tenant's failure to furnish promptly information concerning
         Tenant's requirements pertaining to construction of the Leasehold
         Improvements or any other information requested by the Landlord's
         architect as necessary or useful to prepare the initial drawings,
         plans and specifications which are to comprise the Construction
         Documents;

         (c) Tenant's failure to approve and promptly sign the Construction
         Documents; and

         (d) Tenant's request for any changes in the Leasehold Improvements
         from the work as reflected in the Construction Documents, if Tenant
         has initiated such changes.

<PAGE>   34

      4.02 In any event, Rent payable under the Lease shall not abate by reason
      of any delay, expense or other burden arising out of or incurred in
      connection with the design or construction of the Leasehold Improvements
      to the extent that such delay, expense or other burden is caused in whole
      or in part by any act or omission attributable to Tenant (including,
      without limitation, the acts and omissions referred to in subparagraphs
      (a) through (d) of paragraph 4.01 above).

   5.    Tenant's Access to Leased Premises.

      5.01 Landlord, in its sole discretion, may permit Tenant and Tenant's
      agents or independent contractors to enter the Leased Premises prior to
      the scheduled Lease Commencement Date in order that Tenant may do other
      work as may be required by Tenant to make the Leased Premises ready for
      Tenant's use and occupancy.  Such permission must be in writing prior to
      entry.  If Landlord permits such prior entry, then such license shall be
      subject to the condition that Tenant and Tenant's agents, contractors,
      workmen, mechanics, suppliers, and invitees shall work in harmony and not
      interfere with Landlord and its agents and contractors in doing its work
      in the Leased Premises or the Building or with other tenants and
      occupants of the Building or the Project.  If at any time such entry
      shall cause or threaten to cause disharmony or interference, Landlord, in
      its sole discretion, shall have the right to withdraw and cancel such
      license upon notice to Tenant.  Tenant agrees that any such entry into
      the Leased Premises shall be deemed to be under all of the terms,
      covenants, conditions and provisions of the Lease, except as to the
      covenant to pay periodic Rent.  Tenant further agrees that, to the extent
      permitted by law, Landlord and its principals shall not be liable in any
      way for any injury or death to any person or persons, loss or damage to
      any of the Leasehold Improvements or installations made in the Leased
      Premises or loss or damage to property placed therein or there about, the
      same being at Tenant's sole risk.

      5.02 In addition to any other conditions or limitations on such license
      to enter the Leased Premises prior to the Lease Commencement Date, Tenant
      expressly agrees that none of its agents, contractors, workmen,
      mechanics, suppliers or invitees shall enter the Leased Premises prior to
      the Lease Commencement Date unless and until each of them shall furnish
      Landlord with satisfactory evidence of insurance coverage, financial
      responsibility and appropriate written releases of mechanics' or
      materialmen's lien claims.

   6.    Miscellaneous Provisions.  Landlord and Tenant further agree as
follows:

      6.01 Except as herein expressly set forth with respect to the Leasehold
      Improvements, Landlord has no agreement with Tenant and has no obligation
      to do any work with respect to the Leased





                                     -53-
<PAGE>   35

      Premises.  Any other work in the Leased Premises which may be permitted
      by Landlord pursuant to the terms and conditions of the Lease, including
      any alterations or improvements as contemplated by paragraph 11 of the
      Lease, shall be done at Tenant's sole cost and expense and in accordance
      with the terms and conditions of the Lease.

      6.02 This work letter agreement shall not be deemed applicable to:  (a)
      any additional space added to the original Leased Premises at any time,
      whether by the exercise of any options under the Lease or otherwise, or
      (b) any portion of the original Leased Premises or any additions thereto
      in the event of a renewal or extension of the original Lease Term,
      whether by the exercise of any options under the Lease or any amendment
      or supplement thereto.  The construction of any additions or improvements
      to the Leased Premises not contemplated by this work letter agreement
      shall be effected pursuant to a separate work letter agreement, in the
      form then being used by Landlord and specifically addressed to the
      allocation of costs relating to such construction.

      6.03 Any person signing this work letter agreement on behalf of Tenant
      warrants and represents he has authority to do so.

      6.04 This work letter agreement shall be binding upon and inure to the
      benefit of the parties hereto and their respective heirs, legal
      representatives, successors and assigns.

      6.05 Anything in the Lease to the contrary notwithstanding, notices and
      other items to be delivered pursuant to this work letter agreement shall
      be effective upon receipt of same by the party to whom such notice or
      item is directed.

your approval in the space provided below for that purpose and return to us two
(2) signed counterparts of this work letter agreement.

                                Additional Rent

     The Base Rent Schedule set forth above is based upon a Tenant Improvement
Allowance of $15.25 per usable square foot under this Lease ($76,250.00 total).
Landlord agrees to provide up to $18.25 per usable square foot ($91,250.00
total) as a Tenant Improvement Allowance, provided, however, that the Base Rent
set forth above will be adjusted to allow Landlord to recover the additional
$3.00 Tenant Improvement Allowance (or any part thereof) over the initial term
of the Lease, plus interest at the rate of ten percent (10%) per annum on said
increased amount. The Landlord and Tenant agree to execute an addendum to this
Lease to reflect the change in Base Rent, if any, at such time as the cost of
the Tenant Improvements is known and the rental adjustment calculation can be
made.


                           Tenant Electricity Charges

     Electricity charges have been incorporated into the Base Rent Schedule.
Electricity for extraordinary computer usage or other special uses requiring
excessive electrical power shall be separately metered and paid for by the
Tenant.


                               Operating Expenses

     All operating expenses and taxes are the obligation of the Landlord except
for Tenant's electricity as noted above.
