                  FORD MOTOR COMPANY, INC. AND AVANTGO, INC.
                               January 31, 2000

OVERVIEW                         Ford Motor Company, all its subsidiaries and
                                 affiliates whether wholly owned or controlled
                                 by Ford Motor Company, as well as subsidiaries
                                 and affiliates of Ford Motor Company that
                                 might be spun off during the life of this
                                 Agreement in which latter case the provisions
                                 of this Agreement shall apply only for the
                                 remainder of its term (collectively "Ford") and
                                 AvantGo, Inc. ("AvantGo") propose to amend the
                                 existing Software License Agreement ("SLA") to
                                 enable Ford to broadly deploy AvantGo
                                 Enterprise Interactive Server software
                                 ("AvantGo Software"). AvantGo Software will be
                                 used by Ford employees and contractors.

                                 This term sheet will supersede the SLA in the
                                 event of contradictions in terms.

                                 In addition, the following sections will be
                                 stricken from the SLA:

                                 Section 1 Definitions -- "Confidential
                                 Information" -- Delete second sentence
                                 beginning with, "Confidential Information may
                                 also include oral information....."

                                 Section 12 "Confidentiality of Agreement" --
                                 Delete in its entirety.

                                 AvantGo Software will be used to deliver Ford
                                 automotive content and business applications to
                                 a variety of wireless and casually-connected
                                 handheld devices such as those based on the
                                 PalmOS and WindowsCE operating systems and in-
                                 vehicle systems that may be based on
                                 alternative operating systems.

                                 Ford will be responsible for the management and
                                 support of AvantGo Software on Ford servers at
                                 any of its locations.

                                 enhancements and updates that require AvantGo
                                 to enter into royalty and/or licensing

                                 OFFICE LEASE

     THIS LEASE is entered as of June 23, 1997, by and CORNERSTONE PROPERTIES I,
LLC, a California Limited Liability Company ("Landlord")'and BOMBARDIER SOFTWARE
("Tenant").

     Landlord and Tenant hereby agree as follows:

     1.   PREMISES.

          Subject to the contents of this Lease, Landlord hereby leases to
Tenant and Tenant hereby leases from Landlord the premises described in the
Basic Lease Information Summary (the "Summary") (the "Premises") in the building
described in the Summary (the "Building"), as shown on the floor plan (s)
attached as Exhibit A to this Lease. The Building is part of an office complex
consisting of 1650-1730 S. Amphlett Blvd. (the "Complex"). All measurements of
area contained in this Lease are conclusively agreed to be correct and binding
upon the parties, even if a subsequent measurement of any one of these areas
determines that it is more or less than the amount of area reflected in the
Lease. Any such subsequent determination that the area is more or less than
shown in this Lease shall not result in a change in any of the computations of
rent, improvement allowances or other matters described in this Lease where area
is a factor.

     2.   TERM.

          The term of this lease (the "Term") is Month to Month and commences on
the earlier of (a) the Target Commencement Date; or (b) the date on which Tenant
first occupies all or any portion of the Premises. The dates on which the Term
commences and terminates pursuant to this Article 2 are herein called the
"Commencement Date and the "Expiration Date," respectively. If, for any reason,
Landlord cannot deliver possession of the Premises to. Tenant on or prior to the
Commencement Date, this Lease shall not be void or voidable nor shall Landlord
be liable to Tenant for any loss or damage resulting therefrom. In such case,
Tenant shall not pay any rest and the Commencement Date shall not occur until
such date as Landlord can deliver the Premises, provided, however that if
Landlord's failure to deliver the Premises is attributable to any action or
inaction by Tenant, then the Commencement Date shall not be advanced to the date
on which possession of the Premises is delivered to Tenant and Landlord shall be
entitled to full performance by Tenant (including payment of rent) from the date
the Premises would have been ready for delivery to Tenant but for Tenant's
action or inaction.

     3.   RENT, ADDITIONAL CHARGES.

          3.1 Base Rent. Tenant will pay to Landlord during the Term the monthly
Base Rent set forth in the Summary (the "Base Rent") in consecutive monthly
installments on or before the first day of each calendar month, in advance, at
the address specified for Landlord in the Summary, or such other place as
Landlord may designate in writing, without any prior demand and without any
deductions or setoff. Upon execution of this Lease, Tenant shall pay to Landlord
the first month's Base Rent. If the Commencement Date occurs on a day other than
the first day of a calendar month, or the Expiration Date occurs on a day other
than the last day of a calendar month, then the rental for such fractional month
will be prorated based on a thirty (30) day month.

          3.2 Additional Charges. Tenant shall pay to Landlord all charges and
other amounts required to be paid by Tenant under this Lease (herein called
"Additional Charges") as additional rent at the place where the Base Rent is
payable. Landlord will have the same remedies for a default in the payment of
any Additional Charges as for a default in the payment of Base Rent. (Base Rent
and Additional Charges are sometimes collectively referred to herein as "rent.")

          3.3 Late Charge. If Tenant fails to pay any Base Rent or additional
Charges within five (5) days after the date the same is due and payable, such
unpaid amounts will be subject to a late payment charge equal to ten percent
(10%) of the unpaid amounts in each instance. The late payment charge has been
agreed upon by Landlord and Tenant after negotiation, as a reasonable estimate
of the additional administrative costs and detriment that will be incurred by
Landlord as a result of any such failure by Tenant. the actual costs thereof
being extremely difficult if not impossible to determine. The late payment
charge constitutes liquidated damages to compensate Landlord for its damages
resulting from such failure to pay and shall be paid to Landlord together with
such unpaid amounts.

     4.   ADDITIONAL CHARGES FOR EXPENSES AND REAL ESTATE TAXES.

          4.1 Definition of Expenses. For purposes of this Article 4, the
following terms shall have the
<PAGE>

                                                       Bayshore Corporate Center

meanings set forth in this Section 4.1 "Tenant's Building Percentage Share",
Tenant's Common Area Expense percentage Share" and "Base Year" shall be as set
forth in the Summary. Landlord may adjust these percentages as a result of any
change in the rentable area of the Premises or the total rentable area of the
Building or the other building in the Complex. "Computation Year" means each
calendar year during the Term, including any partial calendar year in which the
Term may commence or terminate. "Real Estate Taxes", "Building Expenses",
"Insurance Expenses" and "Common Area Expenses" are defined in Exhibit B to this
                                                               ---------
Lease.

          4.2 Payment of Charges. From the first day of the thirteenth month of
the Term through the Expiration Date, Tenant shall pay to Landlord as Additional
Charges (i) Tenant's Building Share of the total dollar increase, if any, in
Building Expenses attributable to each Computation Year over Budding Expenses
for the Base Year, (ii) Tenant's Building Share of the total dollar increase, if
any, in Real Estate Taxes attributable to each Computation Year over Real Estate
Taxes for the Base Year, (iii) Tenant's Building Share of the total dollar
increase, if any, in Insurance Expenses attributable to each Computation Year
over Insurance Expenses for the Base Year and (iv) Tenant's Common Area Expense
Share of the total dollar increase, if any, in Common Area Expenses attributable
to each Computation Year over Common Area Expenses for the Base Year. During the
last month of each Computation Year or as soon thereafter as practicable,
Landlord shall give to Tenant notice of Landlord's estimate of the amounts
payable by Tenant for the following Computation Year. On or before the first day
of each month during the following Computation Year, Tenant shall pay to
Landlord one-twelfth (l/12th) of the estimated amounts, provided that until
Landlord gives such notice, Tenant shall continue to pay on the basis of the
prior year's estimate until the first day of the calendar month after Landlord
gives such notice. If at any time or times Landlord determines flint the amounts
payable by Tenant for the current Computation Year will vary from its estimate
given to Tenant, Landlord, by notice to Tenant, may revise its estimate for the
Computation Year, and subsequent payments for the Computation year shall be
based upon the revised estimate. Following the end of each Computation Year,
Landlord shall deliver to Tenant a statement of amounts payable for the
Computation Year. If the statement shows an amount owing by Tenant that is less
than the payments for such Computation Year previously made by Tenant, and if no
Event of Default is outstanding, Landlord shall credit the amount to the next
payments of rent due. If the statement shows an amount owing by Tenant that is
more than the estimated payments for the Computation Year previously made by
Tenant, Tenant shall pay the deficiency to Landlord within thirty (30) days
after delivery of such statement. The respective obligations of Landlord and
Tenant under this Section 4.2 shall survive the Expiration Dale. If the
Commencement Date is a day other than the first day of a Computation Year or the
Expiration Date is a day other than the last day of a Computation Year, the
adjustment in rent pursuant to this Section 4.2 for such Computation Year shall
be prorated based on a 365-day year.
