Mr. James Helfrich
Mr. Scott Kepner
Mr. Robert Issacson
Village Properties
562 Mission Street, Suite 201
San Francisco, CA  94105

Dear Sirs:

Thank you for your  cooperation over the past several months with our evaluation
of candidate sites for Fair,  Isaac's  corporate  facilities  expansion.  As you
know,  Sandy  Greenblat of H&L  Commercial  and AMB have been working with Fair,
Isaac management to determine Fair, Isaac's best course of action. At this time,
we are prepared to recommend that Fair, Isaac & Company,  Inc.  ("Tenant") enter
into a build-to suit lease ("Lease") with Village Properties ("Landlord") on the
following terms:

1.       INITIAL PROCESS

         1.1  Feasibility  Phase.  This letter presents an outline of terms that
both Landlord and Tenant find acceptable  given the parties'  current  knowledge
and understanding of the intended project. Commencing with the execution of this
letter of intent and extending for a period of one hundred and twenty (120) days
(the  "Feasibility  Phase") both  Landlord and Tenant will endeavor to 1) refine
their  respective  understanding  of  the  feasibility  of the  project  through
undertaking design studies,  environmental investigations,  and discussions with
technical  consultants,  public  officials and others;  and 2) draft a lease and
other agreements  incorporating  the terms of this letter with additional detail
as required.  A separate letter agreement will describe  Landlord's and Tenant's
cost responsibility during the Feasibility Phase.

2.       PARTIES & PREMISES

         2.1 Parties.  The parties to the Lease would be Fair,  Isaac & Company,
Inc., a Delaware  corporation and an entity  affiliated  with Village  Builders,
L.P., a California limited partnership. Landlord warrants that Village Builders,
L.P. holds a valid option to purchase the parcels  identified  below as the PG&E
Property and the City of San Rafael has passed a  resolution  to grant an option
to purchase City Property.

         2.2 Area and Location. The initial premises would consist of a building
or buildings to be built  according to plans and  specifications  to be mutually
agreed upon by Tenant and  Landlord,  and  comprising  a total of  approximately
200,000  gross  building  square feet of office space in the initial  phase with
structure  and  on-grade  parking as mutually  agreed upon by the  Parties.  The
project  will be located in San Rafael,  California  on the PG&E  Property.  The
development process for the project is described in Paragraph 5, below.

         2.2.1 PG&E Property.  The PG&E Property  consists of all that presently
unimproved  real  property  commonly  known as 750 & 751  Lindaro  Streets,  San
Rafael,  CA,  further  referred  to as  Assessor's  Parcel  Numbers  13-021-10 &
13-012-12  comprising  approximately 13.97 gross acres (less  dedications),  and
described more fully in Exhibit A.

         1.2.2 City Property.  The City Property  consists of all that presently
improved site  presently  owned by the City of San Rafael  Redevelopment  Agency
located  between the general  boundaries of Second Street on the north,  Lindaro
Street on the west,  San Rafael Creek on the east and the  confluence of Lincoln
Avenue  and San  Rafael  Creek on the  south,  presently  occupied  by the Shell
Service Station at the north end of site and the City of San Rafael  Corporation
Yard on the balance of site.  This parcel is further  referred to as  Assessor's
Parcel Number 13-021-19,  comprising approximately 2.38 acres (less dedications)
and described more fully in Exhibit A.

3.       TERM

         3.1 Term and Commencement.  The term of the Lease would commence thirty
(30) days  following  substantial  completion  of the  tenant  improvements  and
issuance by the City of San Rafael of a Certificate  of Occupancy and extend for
a term of twenty (20) years. The Lease will address issues of phased move-in and
Landlord  and  Tenant  delay  in  construction.   The  parties   anticipate  the
commencement  date to occur not  before  July 1, 1999 and not later than July 1,
2000.

         3.2 Extension Options. Tenant would have four (4) options to extend the
Lease for a term of five (5) years  each,  subject to not less than  twelve (12)
months prior  written  notice.  The annual base rent for each option would be no
more than ninety-five percent (95%) of the Fair Market Rental Value ("FMRV") for
the premises at the start of the additional  term, but in no event less than the
initial base rent.

         FMRV  would  be  defined  in the  Lease as the net  effective  rent per
rentable square foot being charged for comparable space in comparable  buildings
leased on comparable terms including as relevant factors the presence or absence
of tenant  improvement  contributions and rent concessions.  The discount of the
FMRV to ninety five  percent  (95%) would  adjust for the fact that no lost rent
would be incurred by the Landlord and no leasing  commissions would be incurred.
If the  parties  are  unable  to  agree  on the  FMRV  of the  space,  the  rent
determination would be submitted to arbitration through a procedure described in
the Lease.

         In the  alternative,  Tenant would have two options to extend the Lease
for terms of ten (10) years each at ninety-two  and one half percent  (92.5%) of
FMRV.

         3.3  Holdover.  Upon twelve (12) months prior  written  notice,  Tenant
would  have the  option to  holdover  following  expiration  of the  initial  or
extension term of the Lease for a fixed period designated in the notice, but not
exceeding six (6) months,  at a rent equal to one hundred and ten percent (110%)
of the escalated  base rent  applying to the final month of the term.  The Lease
would address holdover rights absent such prior notice.

4.       RENT

         4.1 Initial  Base Rent.  The  initial  annual base rent for the initial
premises  would be  established  by  multiplying  the  Project  Cost  times  the
Development Constant.

                           (10)  Carrying  and  operating   costs   incurred  by
Landlord during the period between Landlord's  purchase of the PG&E Property and
commencement of construction,  including  interest,  property taxes,  insurance,
maintenance  and any other  costs of  ownership,  subject to the  provisions  of
Paragraph 5.6.

         4.1.1.1.2.  All Environmental Issues.

                           (1)  Remediation  including  any  existing and future
obligations and any premiums or costs imposed on the construction of the Project
solely  by  virtue  of  contamination  of the soil or  groundwater.  During  the
Feasibility Phase, the parties will establish a practical method for determining
the amount of this premium, if any.

                           (2) Reports

                           (3) Indemnities

                               50% of Mitigation - Stipulated Price: 
                               $1,000,000.00

         Landlord  and  Tenant  agree that the value of the  property  described
above,  for the  purposes  of  calculating  Phase  One  Project  Costs,  are the
stipulated prices shown above. A portion of the DFPI would be allocated to Phase
One development  with the exact amount depending on site development and parking
strategies. That portion of the DFPI not included in the Project Cost would be a
Forward Cost Item.

         4.1.1.2  Construction  Hard Costs.  The following costs of constructing
the project would be included in the Project Costs.

         4.1.1.2.1  Off-site  Utilities.  The cost of installation of utilities,
including  extensions  to offsite  services,  and  utility  impact  fees will be
included in Phase One Project  Costs  except to the extent  allocable  to future
phases.

         4.1.1.2.2 Site Work and  Landscaping.  The cost of site work,  off-site
work not related to mitigations,  and landscaping  will be included in Phase One
Project Costs except to the extent allocable to future phases.

         4.1.1.2.3  Base  Buildings  Shell  and Core.  The cost of  constructing
approximately 200,000 GSF of office building space will be included in Phase One
Project Cost. The definition of Base Building in relation to Tenant  Improvement
scope of work is outlined in Exhibit D.

         4.1.1.2.4  Parking  Structure(s).  The  cost  of  constructing  parking
structures  as  required  by the design of the  Project  would be  included as a
Project Cost.

         4.1.1.2.5  Tenant  Improvements.  An allowance of twenty-eight  dollars
($28.00)  per gross  square foot of  building  area would be included in Project
Costs.

         4.1.1.3 Soft Costs.  The following  soft costs would be included in the
Project Costs:

         4.1.1.3.1   Architectural  and  Engineering  Fees.   Architectural  and
Engineering  Fees  related to the  planning,  design,  and  construction  of the
Project would be included in the Project Cost.

         4.1.1.3.2  Development  Management  Fees. A Development  Management Fee
would be included in the Project Cost. The amount of the Development  Management
Fee would be established based on comparable fees for similar projects, with the
scope of work excluding the  entitlements  phase of the project.  This fee would
not exceed 2% of Project Cost.

         4.1.1.3.3  Building Permit,  Plan Check and Inspection Fees. These fees
would be included at rates actually incurred.

         4.1.1.3.4 Governmental Fees. Governmental fees, including school, park,
utility district,  and other fees normally imposed on all new office projects in
San Rafael, CA. These fees would be included at rates actually incurred.

         4.1.1.3.5  Construction  Financing.  The  actual  cost of  obtaining  a
construction  loan and the  actual  interest  paid on that loan,  through  lease
commencement,  would be included in Phase One Project  Cost.  Interest  and land
option   payments   related  to  carrying  the  land  through   commencement  of
construction,  subject to  Paragraph  5.6, and  associated  entitlements-related
costs  would  be  excluded.  Landlord  would  finance  actual  costs of land and
entitlements,  as opposed to the Land  Entitlement  Stipulated  Price. The Lease
will contain a provision entitling Tenant to provide substitute financing.

         4.1.1.3.6  Property Tax and  Insurance.  The cost of property taxes and
insurance,  allocated to Phase One, commencing upon construction and terminating
upon Lease Commencement, would be a Project Cost.

         4.1.1.3.7  Permanent  Financing Fees. The cost of obtaining a permanent
loan,  not to exceed two percent (2%) of the loan  amount,  would be included in
Project Cost.

         4.1.1.3.8 Mitigations. The portion of the mitigation and exaction costs
not paid as part of the DFPI will be included in Project Costs.

         4.1.2 Development  Constant.  The Development  Constant will be 110% of
the Mortgage Constant. The Mortgage Constant will be based upon an institutional
loan quote for  funding  upon  completion  of the Phase One  buildings  upon the
following terms:

         Fixed rate; non-recourse;  75% loan to value or 75% loan to cost, to be
determined in the Lease, for 25 year amortization for a 25-year term.

         The  use of the  above  loan-to-cost  criteria  is for the  purpose  of
establishing  a rental rate and is no intended  to limit  Landlord's  ability to
borrow in excess of the 75% loan level,  if it so desires.  Tenant will have the
right to obtain a forward  commitment  on permanent  financing  with the cost of
such financing to be included in Project Costs.

         4.1.3 Example.  Assume the Project Cost equals $38.0  Million.  Further
assume that on the Rent Determination  Date, the interest rate for the benchmark
loan having the  parameters  described  in Paragraph  4.1.2 above,  is 8.55% per
annum. Given a twenty-five (25) year  amortization,  the Mortgage Constant would
equal  9.63%.  This  constant  would then be  multiplied  by 1.10 to produce the
Development  Constant of 10.60%.  The  Development  Constant  would, in turn, be
multiplied by the Project Cost to produce the net rent of $4,025,340 per year.

         4.1.4 Rent  Determination  Dates. The Initial Rent  Determination  Date
will be a date determined by Tenant within thirty (30) days following acceptance
by Landlord and Tenant of a Guaranteed Maximum Price construction  contract.  In
the case in  which  Landlord  and  Tenant  elect  to  purchase  a  forward  loan
commitment  in  advance  of  commencement  of  construction,  the  Initial  Rent
Determination  Date will also be the date on which the commitment to an interest
rate is made. In the case the parties wish to defer the mortgage loan commitment
but the  construction  lender  requires a stated  rental rate,  the rent will be
determined by the same methodology described above except the interest rate will
be based on quoted rates and no loan  commitment  will be made. On the date such
mortgage loan  commitment is made,  the rent will be adjusted  accordingly.  The
Rent will be adjusted within ninety (90) days following  substantial  completion
of the Project to include  any  legitimate  change  order costs in excess of the
Guaranteed  Maximum  Price,  plus actual soft cost  incurred,  multiplied by the
Development Constant.

         4.2  Adjustments.  The  Initial  Base Rent  would be  subject  to a ten
percent (10%) increase on the fifth,  tenth, and fifteenth  anniversaries of the
Lease.

         4.3 Carrying  Costs Related to Future  Development.  It is  anticipated
that the Landlord will incur certain costs and expenses related to preparing the
site to accept future phases of the project ("Forward Cost Items").  Examples of
such Forward Cost Items include, but are not limited to, land, architectural and
engineering fees, site development costs, and utilities  installation costs. The
Lease will describe a procedure to enable Tenant and Landlord to mutually  agree
on a schedule of Forward Cost Items.

         Tenant will pay Landlord, as option payments for the Future Phase land,
upon  commencement  of the Lease term,  the cost of carrying  these Forward Cost
Items at an annual rate equal to the total actual cost of the Forward Cost Items
multiplied  times the  Development  Constant.  Tenant would be  responsible  for
paying any operating  expenses and taxes associated with the Forward Cost Items.
The Lease will  address the  prospect  that future  phase  development  might be
delayed or abandoned,  in which case an equitable  termination  payment would be
made to Landlord.

         4.4 Operating  Expenses and Taxes. The Lease will be "triple net," with
the Tenant  responsible  for payment of all direct  building and site  operating
expenses, including maintenance,  property management, insurance, janitorial and
security  services,  taxes and utilities and amortization or reserves related to
replacement of capital items. Landlord will be responsible for any costs related
to continued  monitoring  and  remediation  of any  environmental  contamination
identified  as of the Lease  Date,  and one half of any  continuing  obligations
imposed on the  project as a special  condition  of  approval  (i.e.,  excluding
municipal taxes,  fees, and imposition  required of all developments as a result
of laws existing as of the Lease date). Tenant will have the right to select and
contract   directly  with  service   providers   (e.g.   janitorial,   landscape
maintenance, etc.) subject to reasonable Landlord approval.

         4.5  Property  Tax  Reassessment.   The  Lease  will  address  Tenant's
requirement  for some  protection  from  increases  in  property  tax  caused by
Landlord's transfer of the project.

5.       DEVELOPMENT OF PROJECT

         5.1  Entitlement  Process.  Landlord will undertake to achieve land use
entitlements for the development of four hundred fifty thousand  (450,000) gross
square feet of  commercial  office  space but in no case less than four  hundred
thousand  (400,000) gross square feet, with parking for not less than 1,600 cars
on the Property.  Tenant would consider a reduced amount of parking if supported
by an analysis of usage patterns and  acceptable to the City of San Rafael.  All
significant  decisions  affecting  the design and phasing of the Project will be
subject to Tenant's  review and  approval.  Landlord  will  consult  with Tenant
regarding  its  conduct  of the  approval  process.  Tenant  will  expeditiously
cooperate with Landlord in the effort to achieve the  entitlements.  Tenant will
have the right to approve all significant  documents related to the development,
including all of the following:  the  application  for planning  review,  the PD
application,  application  for a  vesting  tentative  map,  and the  development
agreement.  All costs related to the  entitlement  process,  including  fees and
project expenses, and consulting expenses incurred by Landlord in furtherance of
the entitlement effort,  will be borne by Landlord.  Tenant will pay the cost of
its own consultants retained to advise it during this process. Architectural and
engineering fees will be paid by Landlord subject to the overall limit described
in Paragraph 4.1.1.3.1.

         5.2  Construction  of Base Buildings and Parking  Structures.  Landlord
will undertake the development of office buildings and parking structures on the
site,   including   site  work  and   landscaping  as  described  in  plans  and
specifications  to be  approved  by  Tenant.  The  cost  of  this  construction,
including governmental fees, permits, construction interest, taxes, and the cost
of architectural,  engineering,  and other consulting  services will be borne by
Landlord.  Exhibit  D  describes  the  scope of base  building  construction  in
relation to the scope of tenant  improvement  construction.  Landlord and Tenant
will cooperate  during the design process to develop a base building design with
flexibility  to enable  eventual  conversion  for  multi-tenant  occupancy.  The
project  will be  developed  on an "open  book"  basis with  respect to all cost
information.

         5.3  Construction of Tenant  Improvements  Landlord would construct all
improvements  to the  premises  in  accordance  with  plans  and  specifications
provided by Tenant,  according to a schedule and procedure  mutually agreed upon
in the Lease. The selection of a general  contractor and  subcontractors for the
tenant  improvement work would be subject to Tenant's  approval.  In the case in
which  Landlord  provides  construction   management  services  for  the  tenant
improvement work, the cost of such services will be charged at prevailing market
rates for similar third party  services.  Landlord may not impose any charge for
review or approval of plans and  specifications,  either for the initial  tenant
improvement  work or for  subsequent  improvements  and  alterations  within the
project.  In the  alternative,  Tenant would have the right to undertake its own
tenant improvement  construction,  subject to notice,  delivery and commencement
provisions to be described in the Lease.

         5.4 Tenant  Improvement  Allowance.  Landlord  would  provide  Tenant a
tenant  improvement  allowance equal to twenty-eight  dollars ($28.00) per gross
square foot of space leased.

         5.5 Limitation on Project Costs and Developer Equity Requirements.  The
Lease will address the legitimate  needs of the Landlord with respect to project
financing.  The method of determining rent based on the Development Constant and
Project Cost assumes a loan ratio of 75% or greater.

         5.6 Timing of  Construction.  The  parties  intend to proceed  with the
project according to the Preliminary Project Schedule attached as Exhibit B. The
Lease will contain a provision that will enable Tenant to defer  commencement of
construction  for the maximum period  allowable by the terms of the  Development
Agreement to be executed between Landlord and the City of San Rafael.

         All  actual   costs  of   deferral   beyond  the  target   construction
commencement  date  will be borne by Tenant as a  current  expense.  The  target
construction  commencement date will be mutually agreed by the parties,  but not
before the later of June 1, 1998 or that date six (6) months  following  receipt
of an executed development agreement,  unless Tenant consents to an earlier date
or the parties agree to a method to allocate  risk  associated  with  proceeding
with architectural work in advance of receipt of final  entitlements.  The Lease
will define the target date and itemize cost categories  related to deferral.  A
similar  provision will apply to construction of the second phase of the project
with the  objective  of affording  Tenant  maximum  flexibility  with respect to
timing the second phase.

6.       OPTIONS TO PURCHASE

         6.1 First  Option to Purchase -  Execution  of  Development  Agreement.
Landlord  grants  Tenant the right to purchase the PG&E Property and to purchase
the  option  to  purchase  the  City  Property,  complete  with  all  plans  and
specifications,  and subject to agreements with the City of San Rafael and other
jurisdictions,  for a price of Ten Million  Dollars  ($10,000,000).  This option
would become  effective upon Execution of the  Development  Agreement and extend
for sixty  (60)  days.  An  adjustment  would be made to the  purchase  price to
reflect  the  cost  of any  obligations  for  which  Landlord  would  have  been
responsible  subject to  Paragraphs  4.1.1.1.1  and 4.1.1.1.2 had the option not
been exercised.  In addition,  Tenant would reimburse Landlord any Project Costs
incurred by Landlord prior to closing.  No  reimbursement  would be made for any
portion of the Development Management Fee.

         6.2 Second  Option to Purchase - Completion  of Phase One  Development.
Landlord  grants  Tenant the right to purchase the PG&E Property and to purchase
the option to  purchase  the City  Property,  including  the  office  buildings,
parking structures,  and other improvements  constructed pursuant to this Lease,
at a price equal to one hundred and ten percent  (110%) of the Project Cost plus
an agreed upon price for Forward Cost Items.  Notice of intent to exercise  this
option would be made no later than sixty (60) days  following  the  execution of
the  development  agreement.  Landlord  would remain  responsible  for all costs
described in Paragraphs 4.1.1.1.1, 4.1.1.1.2 and 4.1.1.1.3. except to the extent
the parties agree to transfer  specified  obligations from Landlord to Tenant in
exchange for an adjustment in the purchase price.  The Lease will provide for an
interest  bearing  deposit or Letter of Credit  adequate to secure the purchase,
and will address  accommodations to Landlord's preference for a closing deferral
of one  year.  Closing  would  occur  on a date  corresponding  to the  intended
Commencement Date of the Lease.

         6.3 Third  Option to Purchase -  Completion  of Phase One  Development.
Landlord grants Tenant the right to purchase the PG&E Property,  and to purchase
the option to  purchase  the City  Property,  including  all  office  buildings,
parking structures,  and other improvements  constructed pursuant to this Lease,
at a price equal to one hundred and thirteen  percent (113%) of the Project Cost
plus an agreed upon price for Forward  Cost Items.  Notice of intent to exercise
this  option  must be made no later  than one  hundred  and  eighty  (180)  days
following  the  Commencement  of the Lease.  Closing  would be  scheduled  for a
mutually  agreed upon date not earlier than the first  anniversary  of the Lease
Commencement.  The Lease will provide for an interest  bearing deposit or Letter
of Credit adequate to secure the purchase.

         6.4 Financing  Limitation The option prices indicated in Paragraphs 6.2
and 6.3 above are  predicated on the  Landlord's  ability to attract  sufficient
equity  capital to the project to enable  construction.  The Lease will  address
those  circumstances  in which the  purchase  price  would be adjusted to enable
financing by third-party equity sources. In addition,  the Lease will describe a
procedure  whereby Tenant would have the right to contribute  cash equity to the
project prior to  construction in exchange for a reduction in the purchase price
corresponding to the value of the avoided financing costs.

         6.4 Right of First  Refusal  to  Purchase.  Throughout  the term of the
Lease,  Tenant  will have the right of first  refusal to purchase  the  Project,
subject to a thirty (30) day response period. The details of this right would be
addressed in the Lease.

7.       DEVELOPMENT OF FUTURE PHASE(S)

         Future  phase or phases are  expected to total from  200,000 to 250,000
gross square feet plus parking (the "Expansion Premises").  The Lease will grant
Tenant  the  option to lease  these  Expansion  Premises  on the same  terms and
conditions as the Lease on the initial Premises, excephere circumstances dictate
an  appropriate  notification.  The Lease will  describe a  procedure  governing
notification,  design, and construction of the Expansion Premises. The rent will
be established  according to the formula presented in Paragraph 3.1. At Tenant's
option,  the term of the Lease with respect to the  Expansion  Premises  will be
coterminous with that of the initial Premises,  but in no case less than fifteen
(15) years. The Lease will contain  assurances  satisfactory to Tenant regarding
Landlord's obligation to develop Phase Two, if so requested.

8.       TERMINATION OF LEASE

         8.1  Tenant's  Option to  Terminate  Lease  Prior to Land  Purchase  by
Landlord.  The Lease will address  issues related to termination of the Lease by
Tenant. In general,  prior to Landlord's  exercise of its option to purchase the
PG&E Property, Tenant will have the right to terminate the Lease upon payment to
Landlord of liquidated  damages in an amount to be stipulated in the Lease based
on Landlord's  projected  overhead costs,  out-of-pocket  costs, and opportunity
costs.

         8.2  Tenant's  Option to Terminate  Lease  Following  Land  Purchase by
Landlord.  Following  Landlord's  purchase  of the PG&E  Property,  but prior to
commencement of construction,  Tenant will have an option to terminate the lease
upon payment to Landlord of Liquidated  Damages in an amount to be stipulated in
the Lease based on Landlord's projected overhead costs, out-of-pocket costs, and
opportunity costs.

         8.3 Termination Due to Landlord Non-Performance. The Lease will provide
Tenant  adequate  security  with  respect  to  Landlord's   performance  of  its
obligations under the Lease.

         8.4 Landlord's Termination Rights.  Landlord may terminate the Lease if
the City of San Rafael fails to grant the necessary entitlements or to execute a
development agreement consistent with the terms of the Lease and Project plans.

9.       Environmental Indemnities.

         Tenant will require  indemnities from Landlord and PG&E with respect to
the PG&E Property,  and from Landlord and the City of San Rafael with respect to
the City Property,  assuring  Tenant that it will bear no risk of  environmental
liability related to the existing condition of the soil and groundwater,  either
as Tenant or as owner.

         During the  Feasibility  Phase,  Tenant will require  cooperation  from
Landlord  regarding access to existing  documents related to the Properties.  In
addition,  Tenant will require Landlord to obtain an agreement from PG&E and the
City  of  San   Rafael   to   undertake   additional   Phase  II   environmental
investigations, subject to Tenant cost reimbursement.

10.      OTHER PROVISIONS

         10.1 Assignment and  Subleasing.  Tenant would have the right to assign
the Lease or sublease  space in the premises  with the consent of the  Landlord,
which consent would not be unreasonably withheld.

         Tenant  would  have the right to assign  the Lease in its  entirety  or
sublease all or a portion of the premises without the consent of the Landlord to
any entity resulting from merger or consolidation with Tenant, or any subsidiary
or affiliate of Tenant.  This waiver of  Landlord's  consent would be contingent
upon the financial worth and  organizational  structure of the resulting  entity
being  greater  than  or  equal  to that of the  Tenant  as of the  date of such
assignment.

         Subsequent to a sublease  notification or sublease,  the Landlord would
have no right to terminate the Lease,  "recapture"  the premises by the right of
first refusal, or otherwise. The Landlord would have no right to additional rent
from subleases entered into by Tenant.

         10.2  Restoration  of  Premises.  Landlord  would  agree to  waive  any
requirement  that  Tenant  restore  the  premises  or  remove  any  improvements
including stairs, floor penetrations,  cabling,  supplemental HVAC units, or any
other construction upon expiration of the Lease.

         10.3  Building  Identity.  Within the terms and  conditions of existing
local  ordinances,  the subject  property will be identified as exclusively  the
site of Fair, Isaac & Co. with signage and/or other identity  designed in such a
way as to compliment the project.  Such identity will be subject to the approval
of Landlord with such approval not to be unreasonably withhold.

         10.4 Tenant  Security.  The Lease will  address  Landlord's  reasonable
concerns with respect to Tenant's financial  capability to undertake the Lease's
obligations.

11.      CESSATION OF TENANT'S SEARCH AND LANDLORD'S MARKETING EFFORTS

         Upon mutual  execution  of this Letter of Intent,  Tenant and  Landlord
agree to end their  respective  search  and  marketing  efforts  related  to the
subject property for a period of one hundred and twenty (120) days.

12.      Non-Binding Agreement

         With the  exception  of  Paragraph  11 above,  this letter is a general
expression  of interest  and does not  constitute a binding  agreement.  Neither
Tenant nor  Landlord  will be bound  until a  definitive,  mutually-satisfactory
lease has been executed and both Tenant and Landlord  warrant that they will not
act in reliance on any terms of this agreement, except Paragraph 11, above.

We would  appreciate  receiving a response by July 14, 1996.  If the above terms
are acceptable to you,  please  indicate by signing in the space provided below.
When  counter-signed  by Fair,  Isaac,  this letter will  constitute a Letter of
Intent with regard to the matters agreed upon.

Sincerely,

AMB CORPORATE REAL ESTATE ADVISORS, INC.
