RE:  Lease  Expansion  Proposal for Forecross  Corporation  at 90 New Montgomery
     Street, San Francisco

Dear Kim:

The following is a preliminary  letter of intent and outlines the basic business
terms and  conditions  of a proposed  lease  between The Canada  Life  Assurance
Company (as  "Landlord")  and  Forecross  Corporation  (as  "Tenant")  at 90 New
Montgomery Street, San Francisco (the "Building").

1.   PREMISES: Approximately 3,974 rentable square feet (suite 1401) on floor 14
     ("Premises").  Exhibit A attached hereto shows the location of the Premises
     on the floor.  Final  space  measurement  would be  subject  to  Landlord's
     architect's review.

2.   TERM:  January 1, 1998 to December 31, 2,001.

3.   COMMENCEMENT:  January 1, 1998 or  upon  delivery  of  Premises  to Tenant,
     whichever is sooner.

4.   BASE RENT:  $ 36.00,per square foot, fully serviced.

5.   TENANT  IMPROVEMENTS:  Tenant  would  accept the  Premises in their "as is"
     configuration and condition.  Prior to Tenant's occupancy the Landlord,  at
     its sole cost and expense,  shall  recarpet and repaint the Premises  using
     building standard finishes.

     An additional  $5.00  per  square  foot  in  tenant  improvements  could be
     Amortized  as additional  rent over the term of the remaining  lease  term.
     The  Landlord  would  use  11%  interest  per  annum  for  amortization  of
     Landlord's costs.

     Landlord would prepare all architectural and  engineering  services  needed
     In  connection  with  the  construction   of  the  tenant  improvements  if
     necessary.  The costs for  architectural  and  engineering  services  would
     be paid out of the Tenant's amortized costs.

6.   BASE YEAR FOR  OPERATING  EXPENSES AND PROPERTY  TAXES:  Calendar Year 1997
     from January 1, 1997 through December 31, 1997 ("Base Year") based an a 95%
     occupied building. Base Year expenses would be included as part of the Base
     Rent.

If in any  calendar  year after the Base Year  operating  expenses  and property
taxes exceed those for the Base Year, Tenant would pay its pro rata share of any
such increase.

7.   SECURITY  DEPOSIT:  One  months'  Base Rent would be held by  Landlord in a
     non-interest bearing account for the lease term.

8.   ADVANCE  RENT:  Tenant  would pay to  Landlord  one (1)  month's  rent upon
     execution of the lease agreement  between Landlord and Tenant.  The advance
     rent would apply to the 1st month's Base Rent payable under the Lease.

9.   AGENCY:  Landlord and Tenant have been  notified and  acknowledge  the fact
     that The CAC Group and NAMCO represent both the Landlord and Tenant in this
     transaction.

10.  FINANCIAL REVIEW:  Tenant is to submit evidence of its financial  condition
     (i.e. financial statements, bank references,  etc.) with this signed letter
     for review and approval by Landlord.

Landlord  requests  that  Tenant  evidence by its  signature  below (1) that the
foregoing correctly reflects the basic business terms upon which Tenant would be
prepared to enter into a lease, and (2) Tenant's  understanding that this letter
of intent is preliminary  only in nature and is not intended to create any legal
obligation  binding on either party. It is to be used as a basis for preparation
of a  definitive  written  lease  which may  contain  materially  additional  or
different  terms and  conditions,  and which will be subject,  in any event,  to
approval in form and  substance by each party and its  respective  counsel.  Any
binding agreement will be only evidenced by such definite lease, so approved and
mutually  executed and delivered by the parties.  We have enclosed a basic lease
information  form which the Tenant  would need to complete in order to allow the
Landlord to properly prepare the lease document.

Tenant is  encouraged  to sign and return one  duplicate of this letter prior to
November 25, 1997, so that we may proceed. Naturally, the matter needs to go

forward promptly and without delay, since the Premises will remain on the market
until a transaction is finally concluded.

As in any real estate  transaction,  it is  recommended  that you consult with a
professional,  such as a civil engineer,  industrial  hygienist or other person,
with the  experience in evaluating  the condition of the property  including the
possible  presence of asbestos,  hazardous  materials  and  underground  storage
tanks.

The parties hereto agree to comply with all applicable federal,  state and local
laws,   regulations,   codes,   ordinances  and  administrative   orders  having
jurisdiction  over the parties,  property or subject  matter of this  agreement,
including,  but not  limited to, the 1964 Civil  Rights Act and all  amendments.
thereto,  the Foreign  Investment  in Real  Property Tax Act, the  Comprehensive
Environmental  Response  Compensation and Liability Act, and The American's With
Disabilities Act.

On behalf of the Landlord, we are excited about the prospect of having Forecross
Corporation  expand  as a tenant in 90 New  Montgomery  Street.  Please  call us
should you have any questions or need additional information.

Sincerely,




/S/ Steven A. Anderson
