ITEM 14. INDEMNIFICATION OF OFFICERS AND DIRECTORS.

     As permitted by Delaware law, our amended and restated certificate of
incorporation provides that no director of ours will be personally liable to us
or our stockholders for monetary damages for breach of fiduciary duty as a
director, except for liability:

     - for any breach of duty of loyalty to us or to our stockholders;

     - for acts or omissions not in good faith or that involve intentional
       misconduct or a knowing violation of law;

     - under Section 174 of the Delaware General Corporation Law; or

     - for any transaction from which the director derived an improper personal
       benefit.

     Our amended and restated certificate of incorporation further provides that
we must indemnify our directors and executive officers and may indemnify its
other officers and employees and agents to the fullest extent permitted by
Delaware law. We believe that indemnification under our amended and restated
certificate of incorporation covers negligence and gross negligence on the part
of indemnified parties.

     We have entered into indemnification agreements with each of our directors
and officers. These agreements, among other things, require us to indemnify each
director and officer for some expenses including attorneys' fees, judgments,
fines and settlement amounts incurred by any of these persons in any action or
proceeding, including any action by or in the right of iPass, arising out of
person's services as our director or officer, any subsidiary of ours or any
other company or enterprise to which the person provides services at our
request.

     The underwriting agreement will provide for indemnification by the
underwriters of iPass, our directors, our officers who sign the registration
statement, and our controlling persons for some liabilities, including
liabilities arising under the Securities Act.

     All schedules are omitted because they are not required, they are not
applicable or the information is already included in the financial statements or
notes thereto.

ITEM 17. UNDERTAKINGS.

     The undersigned registrant hereby undertakes:

          (1) That for purposes of determining any liability under the
     Securities Act, the information omitted from the form of this prospectus
     filed as part of this Registration Statement in reliance upon Rule 430A and
     contained in a form of prospectus filed by the Registrant pursuant to Rule
     424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be
     part of this Registration Statement as of the time it was declared
     effective.

          (2) That for purposes of determining any liability under the
     Securities Act, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of the securities at that
     time shall be deemed to be the initial bona fide offering thereof.

          (3) Insofar as indemnification for liabilities arising under the
     Securities Act may be permitted to directors, officers and controlling
     persons of the Registrant pursuant to the provisions referenced in Item 15
     of this Registration Statement or otherwise, the Registrant has been
     advised that in the opinion of the Securities and Exchange Commission this
     indemnification is against public policy as expressed in the Securities Act
     and is, therefore, unenforceable. In the event that a claim for
     indemnification against these liabilities (other than the payment by the
     Registrant of expenses incurred or paid by a director, officer, or
     controlling person of the Registrant in the successful defense of any
     action, suit or proceeding) is asserted by a director, officer, or
     controlling person in connection with the securities being registered, the
     Registrant will, unless in the opinion of its counsel the matter has been
     settled by controlling precedent, submit to a court of appropriate
     jurisdiction the question of whether the indemnification by it is against
     public policy as expressed in the Securities Act of 1933, and will be
     governed by the final adjudication of this issue.

          (4) To provide to the Underwriters at the closing specified in the
     Underwriting Agreement certificates in the denomination and registered in
     the names required by the Underwriters to permit prompt delivery to each
     purchaser.

the term or sooner termination of this Lease, Tenant shall indemnify Landlord
against loss or liability resulting from the delay by Tenant in so surrendering
the Premises including, without limitation, any claims made by any succeeding
tenant founded on such delay. Nothing contained herein shall be construed as an
extension of the term hereof or as a consent of Landlord to any holding over by
Tenant. The voluntary or other surrender of this Lease or the Premises by Tenant
or a mutual cancellation of this Lease shall not work as a merger and, at the
option of Landlord, shall either terminate all or any existing sublease or
subtenancies or operate as an assignment to Landlord of all or any such
subleases or subtenancies.

9.      ALTERATIONS AND ADDITIONS.

        Tenant shall not make, or suffer to be made, any alteration or addition

unreasonably withheld) but at the cost of Tenant, and any addition to, or
alteration of, the Premises, except moveable furniture and trade fixtures, shall

such alterations and additions. Tenant shall retain title to all moveable
furniture and trade fixtures placed in the Premises. All heating, lighting,
electrical air conditioning, floor to ceiling partitioning, drapery, carpeting,
and floor installation made by Tenant, together with all property that has
become an integral part of the Premises, shall not be deemed trade fixtures.
Tenant agrees that it will not proceed to make such alteration or additions,
without having obtained consent from Landlord to do so, and until five (5) days
from the receipt of such consent, in order that Landlord may post appropriate
notices to avoid any liability to contractors or material suppliers for payment
for Tenant's improvements. Tenant will at all times permit such notices to be
posted and to remain posted until the completion of work. Tenant shall, if
required by Landlord, secure at Tenant's own cost and expense, a completion and
lien indemnity bond, satisfactory to Landlord, for such work. Tenant further
covenants and agrees that any mechanic's lien filed against the Premises or
against the Complex for work claimed to have been done for, or materials claimed
to have been furnished to Tenant, will be discharged by Tenant, by bond or
otherwise, within ten (10) days after the filing thereof, at the cost and
expense of Tenant. Any exceptions to the foregoing must be made in writing and
executed by both Landlord and Tenant. Notwithstanding anything to the contrary
herein, under no circumstances shall Tenant be authorized to penetrate the soil
to a depth that exceeds three and one-half feet from the uppermost surface of

beyond the reasonable control of Landlord.

12.     TAXES.

A. As Additional Rent and in accordance with Paragraph 4 D of this Lease, Tenant
shall pay to Landlord Tenant's proportionate share of all Real Property taxes,
which prorata share shall be allocated to the leased Premises by square footage
or other equitable basis, as calculated by Landlord. The term "Real Property
Taxes", as used herein, shall mean (i) all taxes, assessments, levies and other
charges of any kind or nature whatsoever, general and special, foreseen and
unforeseen (including all installments of principal and interest required to pay
any general or special assessments for public improvements and any increases
resulting from reassessments caused by any change in ownership of the Complex)
now or hereafter imposed by any governmental or quasi-governmental authority or
special district having the direct or indirect power to tax or levy assessments,
which are levied or assessed against, or with respect to the value, occupancy or
use of, all or any portion of the Complex (as now constructed or as may at any
time hereafter be constructed, altered, or otherwise changed) or Landlord's
interest therein; any improvements located within the Complex (regardless of
ownership); the fixtures, equipment and other property of Landlord, real or
personal, that are an integral part of and located in the Complex; or parking
areas, public utilities, or energy within the Complex; (ii) all charges, levies
or fees imposed by reason of environmental regulation or other governmental
control of the Complex; and (iii) all costs and fees (including attorneys' fees)

public authorities as to any Real Property Tax. If at any time during the term
of this Lease the taxation or assessment of the



                                       9.
<PAGE>   10

Complex prevailing as of the commencement date of this Lease shall be altered to
that in lieu of or in addition to any Real Property Tax described above there
shall be levied, assessed or imposed (whether by reason of a change in the
method of taxation or assessment, creation of a new tax or charge, or any other
cause) an alternate or additional tax or charge (i) on the value of the
occupancy of the Complex or Landlord's interest therein or (ii) on a measured by
the gross receipts, income or rentals from the Complex, or Landlord's business
of leasing the Complex, or computed in any manner with respect to the operation
of the Complex, then any such tax or charge, however designated, shall be
included within the meaning of the term "Real Property Taxes" for purposes of
this Lease. If any Real Property Tax is based upon property or rents unrelated
to the Complex, then only that part of such real Property tax that is fairly
allocable to the Complex shall be included within the meaning of the term "Real
Property Taxes". Notwithstanding the foregoing, the term "Real Property Taxes"
shall not include estate, inheritance, gift or franchise taxes of Landlord or
the federal or state net income tax imposed on Landlord's income from all
sources. The term "Real Estate Taxes" shall also include supplemental taxes
related to the period of Tenant's Lease Term whenever levied, including any such
taxes that may be levied after the Lease Term has expired.

        B. TAXES ON TENANT'S PROPERTY

           (a) Tenant shall be liable for and shall pay ten (10) days before
delinquency, taxes levied against any personal property or trade fixtures placed
by Tenant in or about in the Premises. If any such taxes on Tenant's personal
property or trade fixtures are levied against Landlord or Landlord's property or
if the assessed value of the Premises is increased by the inclusion therein of a
value placed upon such personal property or trade fixtures of Tenant and if
Landlord, after written notice to Tenant, pays the taxes based on such increased
assessments, which Landlord shall have the right to do regardless of the
validity thereof, but only under proper protest if requested by Tenant. Tenant
shall upon demand, as the case may be, repay to Landlord the taxes so levied
against Landlord, or the proportion of such taxes resulting from such increase
in the assessment; provided that in any such event Tenant shall have the right,
in the name of Landlord and with Landlord's full cooperation, to bring suit in
any court of competent jurisdiction to recover the amount of any such taxes so
paid under protest, and any amount so recovered shall belong to Tenant.

           (b) if the Tenant improvements in the Premises, whether installed,
and/or paid for by Landlord or Tenant and whether or not affixed to the real
property so as to become a part thereto, are assessed for real property tax
purposes at a valuation higher than the valuation to which standard office
improvements in other space in the Complex are assessed, then the real property
taxes and assessments levied against Landlord or the Complex by reason of such
excess assessed valuation shall be deemed to be taxes levied against personal
property of Tenant and shall be governed by the provisions of 12B(a) above. If
the records of the County Assessor are available and sufficiently detailed to
serve as a basis for determining whether said Tenant improvements are assessed
at a higher valuation than standard office improvements in other space in the
Complex, such records shall be binding on both the Landlord and the Tenant. If
the records of the County Assessor are not available or sufficiently detailed to
serve as a basis for making said determination, the actual cost of construction
shall be used.

13.     LIABILITY INSURANCE.

increase. Tenant shall have no interest in nor any right to the proceeds of any
insurance procured by Landlord for the Complex.

Landlord and Tenant do each hereby respectively release the other, to the extent
of insurance coverage of the releasing party, from any liability for loss or
damage caused by fire or any of the extended coverage casualties included in the
releasing party's insurance policies,


                                      11.
<PAGE>   12

irrespective of the cause of such fire or casualty; provided, however, that if
the insurance policy or either releasing party prohibits such waiver, then this
waiver shall not take effect until consent to such waiver is obtained. If such
waiver is so prohibited, the insured party affected shall promptly notify the
other party thereof.

16.     INDEMNIFICATION.

        Landlord shall not be liable to Tenant and Tenant hereby waives all

contractors of which negligence Landlord has knowledge and reasonable time to
correct. Except as to injury to persons or damage to property to the extent
arising from the willful misconduct or the negligence of Landlord, its agents,
servants, employees, invitees, or contractors, Tenant shall hold Landlord
harmless from and defend Landlord against any and all expenses, including
reasonable attorneys' fees, in connection therewith, arising out of any injury
to or death of any person or damage to or destruction of property occurring in,
on or about the Premises, or any part thereof, from any cause whatsoever.

17.     COMPLIANCE.

        Tenant, at its sole cost and expense, shall promptly comply with all
laws, statues, ordinances and governmental rules, regulations or requirements
now or hereafter in effect; with the requirements of any board of fire
underwriters or other similar body now or hereafter constituted; and with any
direction or occupancy certificate issued pursuant to law by any public officer;
provided, however, that no such failure shall be deemed a breach of the
provisions if Tenant, immediately upon notification, commences to remedy or
rectify said failure. The judgment of any court of competent jurisdictions or
the admission of Tenant in any action against Tenant, whether Landlord be a
party thereto or not, that Tenant has violated any such law, statute, ordinance
or governmental rule, regulation, requirement, direction or provision, shall be
conclusive of that fact as between Landlord and Tenant. This paragraph shall not
be interpreted as requiring Tenant to make structural changes or improvements,
except to the extent such changes or improvements are required as a result of
Tenant's use of the Premises. Tenant shall, at its sole costs and expense,
comply with any and all requirements pertaining to said Premises, of any
insurance organization or company, necessary for the maintenance of reasonable
fire and public liability insurance covering the Premises.

18.     LIENS.

addition to all other remedies provided herein and by law, the right, but no
obligation, to cause the same to be released by such means as it shall deem
proper, including payment of the claim giving rise to such lien. All sums paid
by Landlord for


                                      12.
<PAGE>   13

such purpose, and all expenses incurred by it in connection therewith, shall be
payable to Landlord by Tenant on demand with interest at the prime rate of
interest as quoted by the Bank of America.

19.     ASSIGNMENT AND SUBLETTING.

Tenant shall not assign, transfer, or hypothecate the leasehold estate under
this Lease, or any interest therein, and shall not sublet the Premises, or any
part thereof, or any right or privilege appurtenant thereto, or suffer any other
person or entity to occupy or use the Premises, or any portion thereof, without,
in each case, the prior written consent of Landlord which consent will not be
unreasonably withheld. As a condition for granting this consent to any
assignment, transfer, or subletting, Landlord shall require Tenant to pay to
Landlord as Additional Rent, seventy-five (75%) percent of all rents and/or
additional consideration due Tenant from its assignees, transferees or
subtenants in excess of the Rent payable by Tenant to Landlord hereunder for the
assigned, transferred and/or subleased space ("Excess Rent"); provided, however,
that before sharing such Excess Rent, Tenant shall first be entitled to recover
from such Excess Rent the amount of any reasonable leasing commissions related
to said transaction paid by Tenant to third party brokers not affiliated with
Tenant. Tenant shall by thirty (30) days written notice, advise Landlord of its
intent to assign or transfer Tenant's interest in the Lease or sublet the
Premises or any portion thereof for any part of the term hereto. Within
thirty(30) days after receipt of said written notice, Landlord may, in its sole
discretion, elect to terminate this Lease as to the portion of the Premises
described in Tenant's notice on the date specified in Tenant's notice by giving
written notice of such election to termination. If no such notice to terminate
is given to Tenant within said thirty (30) day period, Tenant may proceed to
locate an acceptable sublessee, assignee, or other transferee for presentment to
Landlord for Landlord's approval, all in accordance with the terms, covenants,
and conditions of this paragraph 19. If Tenant intends to sublet the entire
Premises and Landlord elects to terminate this Lease, this Lease shall be
terminated on the date specified in Tenant's notice. If, however, this Lease
shall terminate pursuant to the foregoing with respect to less than all the
Premises, the rest, as defined and reserved hereinabove shall be adjusted on a
pro rata basis to the number of square feet retained by Tenant, and this Lease
as so amended shall continue in full force and effect. In the event Tenant is
allowed to assign, transfer or sublet the whole or any part of the Premises,
with the prior written consent of Landlord, no assignee, transferee or subtenant
shall assign or transfer this Lease, either in whole or in part, or sublet the
whole or any part of the Premises, without also having obtained the prior
written consent of Landlord. A consent of Landlord to one assignment, transfer,
hypothecation, subletting, occupation or use by any other person shall not
release Tenant from any of Tenant's obligations hereunder or be deemed to be a
consent to any subsequent similar or dissimilar assignment, transfer,
hypothecation, subletting, occupation or use by any other person. Any such
assignment, transfer, hypothecation, subletting, occupation or use without such
consent shall be void and shall constitute a breach of the Lease by Tenant and
shall, at the option of Landlord exercised by written notice to Tenant,
terminate this Lease. The leasehold estate under this Lease shall not, nor shall
any interest therein, be assignable for any purpose by operation of law without
the written consent of Landlord. As a condition to its consent, Landlord shall
require Tenant to pay all expenses in connection with the assignment, and
Landlord shall require Tenant's assignee or transferee (or other assignees or
transferees) to assume in writing all of the obligations under this Lease and
for Tenant to remain liable to


                                      13.
<PAGE>   14

Landlord under the Lease. Notwithstanding the above, in no event will Landlord
consent to a sub-sublease.

20.     SUBORDINATION AND MORTGAGES.

        In the event Landlord's title or leasehold interests is now or hereafter
encumbered by a deed of trust, upon the interest of Landlord in the land and
buildings in which the demised Premises are located, to secure a loan from a
lender (hereinafter referred to as "Lender") to Landlord, Tenant shall, at the
request of Landlord or Lender, execute in writing an agreement subordinating its
rights under this Lease to the lien of such deed of trust, or, if so requested,
agreeing that the lien of Lender's deed of trust shall be or remain subject and
subordinate to the rights to Tenant under this Lease. Notwithstanding any such
subordination, Tenant's possession under this Lease shall not be disturbed if
Tenant is not in default and so long as Tenant shall pay all rent and observe
and perform all of the provisions set forth in this Lease.

21.     ENTRY BY LANDLORD.

        Landlord reserves, and shall at all reasonable times after at least 24
hours notice (except in emergencies) have, the right to enter the Premises to
inspect them; to perform any services to be provided by Landlord hereunder, to
submit the Premises to prospective purchasers, mortgagers or tenants; to post
notices of nonresponsibility; and to alter, improve or repair the Premise and
any portion of the Complex, all without abatement of rent; and may erect
scaffolding and other necessary structures in or through the Premises where
reasonably required by the character of the work to be performed; provided,
however, that the business of Tenant shall be interfered with to the least
extent that is reasonably practical. For each of the foregoing purposes,
Landlord shall at all times have and retain a key with which to unlock all of
the doors in an emergency in order to obtain entry to the Premises, and any
entry to the Premises obtained by Landlord by any of said means, or otherwise,
shall not under any circumstances be construed or deemed to be a forcible or
unlawful entry into or a detainer of the Premises or an eviction, actual or
constructive, of Tenant from the Premises or any portion thereof. Landlord shall
also have the right at any time to change the arrangement or location of
entrances or passageways, doors and doorways, and corridors, elevators, stairs,
toilets or other public parts of the Complex and to change the name, number or
designation by which the Complex is commonly known, and none of the foregoing
shall be deemed an actual or constructive eviction of Tenant, or shall entitle
Tenant to any reduction of rent hereunder.

22.     BANKRUPTCY AND DEFAULT.

        The commencement of a bankruptcy action or liquidation action or
reorganization action or insolvency action or an assignment of or by Tenant for
the benefit of creditors, of any similar action undertaken by Tenant, or the
insolvency of Tenant, shall at Landlord's option, constitute a breach of this
Lease by Tenant. If the trustee or receive appointed to serve during a
bankruptcy, liquidation, reorganization, insolvency or similar action elects to
reject Tenant's unexpired Lease, the trustee or receiver shall notify Landlord
in writing of its election within thirty (30) days after an order for relief in
a liquidation action or within thirty (30) days after the commencement of any
action.




                                      14.
<PAGE>   15

        Within thirty (30) days after court approval of the assumption of this
Lease, the trustee or receiver shall cure (or provide adequate assurance to the
reasonable satisfaction of Landlord that the trustee or receiver shall cure) any
and all previous defaults under the unexpired Lease and shall compensate
Landlord for all actual pecuniary loss and shall provide adequate assurance of
future performance under said Lease to the reasonable satisfaction of Landlord.
Adequate assurance of future performance, as used herein, include, but shall not
be limited to: (i) assurance of source and payment of rent and other
consideration due under this Lease; (ii) assurance that the assumption or
assignment of this Lease will not breach substantially any provisions, such as
radius, location, use, or exclusivity provision, in any agreement relating to
the above described Premises.

        Nothing contained in this section shall affect the existing right of
Landlord to refuse to accept an assignment upon commencement of or in connection
with a bankruptcy, liquidation, reorganization or insolvency action or an
assignment of Tenant for the benefit of creditors or other similar act. Nothing
contained in this Lease shall be construed as giving or granting or creating an
equity in the demised Premises to Tenant. In no event shall the leasehold estate
under this Lease, or any interest therein, be assigned by voluntary or
involuntary bankruptcy proceeding without the prior written consent of Landlord.
In no event shall this Lease or any right or privileges hereunder be an asset of
Tenant under any bankruptcy, insolvency or reorganization proceedings.

        The failure to perform or honor any covenant, condition or
representation made under this Lease shall constitute a default hereunder by
Tenant upon expiration of the appropriate grace period hereinafter provided.
Tenant shall have a period of five (5) days from the date of written notice from
Landlord within which to cure any default in the payment of rental or adjustment
thereto. Tenant shall have a period of thirty (30) days from the date of written
notice from Landlord within which to cure any other default under this Lease,
provided, however, that if the nature of Tenant's failure is such that more than
thirty (30) days is reasonably required to cure the same, Tenant shall not be in
default so long as Tenant commences performance within such thirty (30) day
period and thereafter prosecutes the same to completion. Upon an uncured default
of this Lease by Tenant, Landlord shall have the following rights and remedies
in addition to any other rights or remedies available to Landlord at law or in
equity:

           (a) The rights and remedies provided for by California Civil Code
Section 1951.2, including but not limited to, recovery of the worth at the time
of award of the amount by which the unpaid rent for the balance of the term
after the time of award exceeds the amount of rental loss for the same period
that Tenant proves could be reasonably avoided as computed pursuant to
subsection(b) of said Section 1951.2. Any proof by Tenant under subparagraph (2)
and (3) of Section 1951.2 of the California Civil Code of the amount of rental
loss that could be reasonably avoided shall be made in the following manner.
Landlord and Tenant shall each select a licensed real estate broker in the
business of renting property of the same type and use as the Premises and in the
same geographic vicinity. Such two real estate brokers shall select a third
licensed real estate broker, and the three licensed real estate brokers so
selected shall determine the amount of the rental loss that could be reasonably
avoided from the balance of the term of this Lease after the time of award. The
decision of the majority of said licensed real estate brokers shall be final and
binding upon the parties hereto.




                                      15.
<PAGE>   16

           (b) The right and remedies provided by California Civil Code Section
which allows Landlord to continue the Lease in effect and to enforce all of its
rights and remedies under this Lease, including the right to recover rent as it
becomes due, for so long as Landlord does not terminate Tenant's right to
possession; acts of maintenance or preservation, efforts to relet the Premises,
or the appointment of a receiver upon Landlord's initiative to protect its
interests under this Lease shall not constitute a termination of Tenant's right
to possession.

           (c) The right to terminate this Lease by giving notice to Tenant in
accordance with applicable law.

           (d) To the extent permitted by law the right of power, to enter the
Premises and remove therefrom all persons and property, to store such property
in a public warehouse or elsewhere at the cost of and for the account of Tenant,
and to sell such property and apply such proceeds therefrom pursuant to
applicable California law. Landlord, may from time to time sublet the Premises
or any part thereof for such term or terms (which may extend beyond the term of
the Lease) and at such rent and such other terms as Landlord in its sole
discretion may deem advisable, with the right to make alterations and repairs to
the Premises. Upon each subletting, (i) Tenant shall be immediately liable to
pay Landlord, in addition to indebtedness other than rent due hereunder, the
cost of such subletting, including, but not limited to, reasonable attorney's
fees and any real estate commissions actually paid, and the cost of such
alteration and repairs incurred by Landlord and the amount, if any, by which the
rent hereunder for the period of such subletting (to the extent such period does
not exceed the term hereof) exceeds the amount to be paid as rent for the
Premises for such period or (ii) at the option of Landlord, rents received from
such subletting shall be applied first to payment of indebtedness other than
rent due hereunder from Tenant to Landlord; second, to the payment of any costs
of such subletting and of such alterations and repairs; third to payment of rent
due and unpaid hereunder, and the residue, if any, shall be held by Landlord and
applied to payment of future rent as the same becomes due hereunder. If Tenant
has been credited with any rent to be received by such subletting under option
(i) and such rent shall not be promptly paid to Landlord by the subtenant(s), or
if such rentals received from such subletting under option (ii) during any month
by less than that to be paid during the month by Tenant hereunder. Tenant shall
pay any such deficiency to Landlord. Such deficiency shall be calculated and
paid monthly. No taking possession of the Premises by Landlord, shall be
construed as an election on its part to terminate this Lease unless a written
notice of such intention be given to Tenant. Notwithstanding any such subletting
without termination, Landlord may at any time hereafter elect to terminate this
Lease for such previous breach.

           (e) The right to have a receiver appointed for Tenant upon
application by Landlord, to take possession of the Premises and to apply any
rental collected from the Premises and to exercise all other rights and remedies
granted to Landlord pursuant to subparagraph (d) above.

23.     ABANDONMENT.

Tenant shall not vacate or abandon the Premises at any time during the term of
this Lease and if Tenant shall abandon, vacate or surrender the Premises, or be
dispossessed by the process of law, or otherwise, any personal property
belonging to Tenant and left on the Premises shall be



                                      16.

deemed to be abandoned, at the option of Landlord, except such property as may
be mortgage to Landlord.

24.     DESTRUCTION.

        In the event the Premises are destroyed in whole or in part form any
cause, except for routine maintenance and repairs and incidental damage and
destruction caused form vandalism and accidents for which Tenant is responsible
for under Paragraph 10, Landlord may, at its option:

           (a) Rebuild or restore the Premises to the condition prior to the
damage or destruction; or

           (b) Terminate this Lease, (providing that the Premises is damaged to
the extent of 33 1/3% of the replacement cost). If Landlord does not give Tenant
notice in writing within thirty (30) days from the destruction of the Premises
of its election to either rebuild and restore them, or to terminate this Lease,
Landlord shall be deemed to have elected to rebuild or restore them, in which
event Landlord agrees, at its expense, promptly to rebuild or restore the
Premises to their condition prior to the damage or destruction. Tenant shall be
entitled to a reduction in rent while such repair is being made in the
proportion that the area of the Premises rendered untenantable by such damage
bears to the total area of the Premises. If Landlord initially estimates that
the rebuilding or restoration will exceed one hundred eighty (180) days or if
Landlord does not complete the rebuilding or restoration within one hundred
eighty (180) days following the date of destruction (such period of time to be
extended for delays caused by the fault or neglect of Tenant or because of acts
of God, acts of public agencies, labor disputes, strikes, fires, freight
embargoes, rainy or stormy weather, inability to obtain materials, supplies or
fuels, acts of contractors or subcontractors, or delay of the contractors or
subcontractors due to such causes or other contingencies beyond the control of
Landlord), then Tenant shall have the right to terminate this Lease by giving
fifteen (15) days prior written notice to Landlord. Notwithstanding anything
herein to the contrary. Landlord's obligation to rebuild or restore shall be
limited to the building and interior improvements constructed by Landlord as
they existed as of the commencement date of the Lease and shall not include
restoration of Tenant's trade fixtures, equipment, merchandise, or any
improvements, alterations or additions made by Tenant to the Premises, which
Tenant shall forthwith replace or fully repair at Tenant's sole cost and expense
provided this Lease is not cancelled according to the provisions above.

        Unless this Lease is terminated pursuant to the foregoing provisions,
this Lease shall remain in full force and effect. Tenant hereby expressly waives
the provisions of Section 1932, Subdivision 2, in Section 1933, Subdivision 4 of
the California Civil Code.

        In the event that the building in which the Premises are situated is
damaged or destroyed to the extent of not less than 33 1/8 % of the replacement
cost thereof, Landlord may elect to terminate this Lease, whether the Premises
be injured or not. Notwithstanding anything to the contrary herein, Landlord may
terminate this Lease in the event of an uninsured event or if insurance proceeds
are insufficient to cover one hundred percent of the rebuilding costs net of the
deductible.

25.     EMINENT DOMAIN.

        If all or any part of the Premises shall be taken by any public or
quasi-public authority under the power of eminent domain or conveyance in lieu
thereof, this Lease shall terminate as to any portion of the Premises so taken
or conveyed on the date when title vests in the condemnor, and Landlord shall be
entitled to any and all payment, income, rent, award, or any interest therein
whatsoever which may be paid or made in connection with such taking or
conveyance, and Tenant shall have no claim against Landlord or otherwise for the
value of any unexpired term of this Lease. Notwithstanding the foregoing
paragraph, any compensation specifically awarded Tenant for loss of business,
Tenant's personal property, moving cost or loss of goodwill, shall be and remain
the property of Tenant.

        If (i) any action or proceeding is commenced for such taking of the
Premises or any part thereof, or if Landlord is advised in writing by any entity
or body having the right or power of condemnation of its intention to condemn
the premises or any portion thereof, or (ii) any of the foregoing events occur
with respect to the taking of any space in the Complex not leased hereby, or if
any spaces so taken or conveyed in lieu of such taking and Landlord shall decide
to discontinue the use and operation of the Complex, or decide to demolish,
alter or rebuild the Complex, then, in any of such events Landlord shall have
the right to terminate this Lease by giving Tenant written notice thereof within
sixty (60) days of the date of receipt of said written advice, or commencement
of said action or proceeding, or taking conveyance, which termination shall take
place as of the first to occur of the last day of the calendar month next
following the month in which such notice is given or the date on which title to
the Premises shall vest in the condemnor.

        In the event of such a partial taking or conveyance of the Premises, if
the portion of the Premises taken or conveyed is so substantial that the Tenant
can no longer reasonably conduct its business, Tenant shall have the privilege
of terminating this Lease within sixty (60) days from the date of such taking or
conveyance, upon written notice to Landlord of its intention so to do, and upon
giving of such notice this Lease shall terminate on the last day of the calendar
month next following in which such notice is given, upon payment by Tenant of
the rent form the date of such taking or conveyance to the date of termination.

        If a portion of the Premises be taken by condemnation or conveyance in
lieu thereof and neither Landlord nor Tenant shall terminate this Lease as
provided herein, this Lease shall continue in full force and effect as to the
part of the Premises not so taken or conveyed, and the rent herein shall be
apportioned as of the date of such taking or conveyance so that thereafter the
rent to be paid by Tenant shall be in the ratio that the area of the portion of
the Premises not so taken or conveyed bears to the total area of the Premises
prior to such taking.

26.     SALE OR CONVEYANCE BY LANDLORD.

In the event of a sale or conveyance of the Complex or any interest therein, by
any owner of the reversion then constituting Landlord, the transferor shall
thereby be released form any further liability upon any of the terms, covenants
or conditions (express or implied) herein contained in favor of Tenant, and in
such event, insofar as such transfer is concerned. Tenant agrees to look solely
to the responsibility of the successor in interest of such transferor in and to


                                      18.
<PAGE>   19

shall not be affected by any such sale or conveyance, and Tenant agrees, upon
recognition, to attorn to the successor in interest of such transferor.

27.     ATTORNMENT TO LENDER OR THIRD PARTY.

        In the event the interest of Landlord in the land and buildings in which
the leased Premises are located (whether such interest of Landlord is a fee
title interest or a leasehold interest) is encumbered by deed of trust, and such
interest is acquired by the lender or any third party through judicial
foreclosure or by exercise of a power of sale at private trustee's foreclosure
sale. Tenant hereby agrees, upon recognition, to attorn to the purchaser at any
such foreclosure sale and to recognize such purchaser as the Landlord under this
Lease. In the event lien of the deed of trust securing the loan from a Lender to
Landlord is prior and paramount to the Lease, this Lease shall nonetheless
continue in full force and effect for the remainder of the unexpired term
hereof, at the same rental herein reserved and upon all the other terms,
conditions and covenants herein contained.

28.     HOLDING OVER.

        Any holding over by Tenant after expiration or other termination of the
term of this Lease with the written consent of Landlord delivered to Tenant
shall not constitute a renewal or extension of the Lease or give Tenant any
rights in or to the leased Premises except as expressly provided in this Lease.
Any holding over after the expiration or other termination f the term of this
Lease, with the consent of Landlord, shall be construed to be a tenancy from
month to month, on the same terms and conditions herein specified insofar as
applicable except that the monthly Basic Rent shall be increased to an amount
equal to one hundred fifty (150%) percent of the monthly Basic Rent required
during the last month of the Lease term.

29.     CERTIFICATE OF ESTOPPEL.

        Tenant shall at any time upon not less than ten (10) days' prior written
notice to Landlord execute, acknowledge and deliver to Landlord a statement in
writing (i) certifying that this Lease is unmodified and in full force and
effect (or, if modified, stating the nature of such modification and certifying
that this Lease, as so modified, is in full force and effect) and the date to
which the rent and other charges are paid in advance, if any, and (ii)
acknowledging that there are not, to Tenant's knowledge, any uncured defaults on
the part of Landlord hereunder, or specifying such defaults, if any, are
claimed. Any such statmeent may be conclusively relied upon by any prospective
purchaser or encumbrancer of the Premises. Tenant's failure to deliver such
statement with in such time shall be conclusive upon Tenant that this Lease is
in full force and effect, without modification except as may be represented by
Landlord; that there are no uncured defaults in Landlord's performance, and that
not more than one month's rent has been paid in advance.

30.     CONSTRUCTION CHANGES.

ductwork, plumbing and other facilities therein are subject to such minor
changes as Landlord or Landlord's architect determines to be desirable in the
course of construction of the Premises, and

shall affect this Lease or entitle Tenant to any reduction of rent hereunder or
result in any liability of Landlord to Tenant. Landlord does not guarantee the
accuracy of any drawings supplied to Tenant and verification for the accuracy of
such drawings rests with Tenant.

observed by Tenant shall be performed or observed by Tenant at Tenant's sole

failure shall continue for five (5) days after written notice thereof by
Landlord, or shall fail to perform any other term or covenant hereunder on its
part to be performed, and such failure shall continue for thirty (30) days after
written notice thereof by Landlord, Landlord, without waiving or releasing
Tenant from any obligation of Tenant hereunder, may, but shall not be obligated
to, make any such payment or perform any such other term or covenant on Tenant's
part to be performed. All sums so paid by Landlord and all necessary costs of
such performance by Landlord together with interest thereon at the rate of the
prime rate of interest per annum as quoted by the Bank of America from the date
of such payment or performance by Landlord, shall be paid (and Tenant covenants
to make such payment) to Landlord on demand by Landlord, and Landlord shall have
(in addition to any other right or remedy of Landlord) the same rights and
remedies in the event of nonpayment by Tenant as in the case of failure by

therein contained, and no custom or practice which may develop between the
parties hereto during the term hereof shall be deemed a waiver of, or in any way

between the parties that after Landlord makes the interior improvements as shown
on EXHIBIT B, Landlord shall not be required to make, nor be responsible for any
cost, in connection with any repair, restoration, and/or improvement to the
Premises in order for this Lease to commence, or thereafter, throughout the Term
of this Lease. Notwithstanding anything to the contrary within this Lease,
Landlord makes no warranty or representation of any kind or nature whatsoever as
to the condition or repair of the Premises, nor as to the use or occupancy which
may be made thereof.

44.   TENANT INTERIOR IMPROVEMENTS.

      Landlord shall, at its sole cost and expense, construct certain interior
improvements (the "Tenant Improvements") in the Premises, as shown on EXHIBIT B
to be attached to the Lease and Landlord agrees to deliver the Premises leased
hereunder to Tenant, at Landlord's expense, in the configuration shown in Red on
EXHIBIT B to be attached hereto. Notwithstanding anything to the contrary above,
it is specifically understood and agreed that Landlord shall be required to
furnish only a standard air conditioning/heating system, normal electrical
outlets, standard fire sprinkler systems, standard bathroom, standard lobby, 2'
x 4' suspended acoustical tile drop ceiling throughout the entire space leased,
carpeting and/or vinyl-coated floor tile, and standard office partitions and
doors, as shown on EXHIBIT B to be attached hereto; provided, however, that any
special HVAC and/or plumbing and/or electrical requirements over and above that
normally supplied by Landlord shall be 100 percent the responsibility of and be
paid for 100 percent by Tenant.

      It is further agreed that Tenant shall furnish Landlord with Tenant's
required specifications and a preliminary space plan showing the layout of the
improvements to be constructed in the Premises by November 15, 1999. At that
time, Landlord shall have the final interior plans drawn by Landlord's
architect. All of the plans and specifications shall be EXHIBIT B to this Lease.
If said preliminary plans and specifications for any items affecting the
interior improvements to be constructed in the building are not received by
Landlord for Landlord's approval (which approval shall not be unreasonably
withheld) by November 15, 1999, then it is


                                      26.
<PAGE>   27

agreed that, notwithstanding anything to the contrary in this Lease, this Lease
and Tenant's obligation to perform all terms, covenants and conditions of this
Lease shall commence February 15, 2000, regardless of whether or not the
building and interior improvements are completed on February 15, 2000, and
Landlord shall complete construction of the interior improvements as soon as
reasonably possible thereafter.

      Notwithstanding anything to the contrary, it is agreed that in the event
Tenant makes changes, additions or modifications to the plans and specifications
to be constructed by Landlord as set forth herein, or improvements are installed
for Tenant in excess of those to be provided Tenant by Landlord as set forth on
EXHIBIT B, any increased cost(s) resulting from said changes, additions and/or
modifications and/or improvements in excess of those to be provided Tenant shall
be contracted for with Landlord and paid for one hundred percent (100%) by
Tenant.

      The interior shall be constructed in accordance with EXHIBIT B of the
Lease, it being agreed, however, that if the interior improvements constructed
by Landlord relating thereto, do not conform exactly to the plans and
specifications as set forth in the Lease, and the general appearance, structural
integrity, and Tenant's uses and occupancy of the Premises and interior
improvements relating thereto are not materially or unreasonably affected by
such deviation, it is agreed that the commencement date of the Lease, and
Tenant's obligation to pay rental, shall not be affected, and Tenant hereby
agrees, in such event, to accept the Premises and interior improvements as
constructed by Landlord.

      Tenant shall have thirty (30) days after the Commencement Date to provide
Landlord with a "punch list" pertaining to Landlord's work with respect to
Tenant's interior improvements. As soon as reasonably possible thereafter,
Landlord, or one of Landlord's representatives (if so approved by Landlord), and
Tenant shall conduct a joint walk-through of the Premises (if Landlord so
requires), and inspect such Tenant Improvements, using their best efforts to
agree on the incomplete or defective construction related to the Tenant
Improvements installed by Landlord. After such inspection has been completed,
Landlord shall prepare, and both parties shall sign, a list of all "punch list"
items which the parties reasonably agree are to be corrected by landlord (but
which shall exclude any damage or defects caused by Tenant, its employees,
agents or parties Tenant has contracted with to work on the Premises). landlord
shall have thirty (30) days thereafter (or longer if necessary, provided
Landlord is diligently pursuing the completion of the same) to complete, at
Landlord's expense, the repairs on the "punch list" without the Commencement
Date of the Lease and Tenant's obligation to pay Rental thereunder being
affected. This Paragraph shall be of no force and effect if Tenant shall fail to
give any such notice to Landlord within thirty (30) days after the Commencement
Date of this Lease.

45.   CONSENT.

      Whenever the consent of one party to the other is required hereunder, such
consent shall not be unreasonably withheld.

46.   CHOICE OF LAW; SEVERABILITY.

      This Lease shall in all respects be governed by and construed in
accordance with the laws of the State of California. If any provisions of this
Lease shall be invalid, unenforceable or



                                      27.
<PAGE>   28

ineffective for any reason whatsoever, all other provisions hereof shall be and
remain in full force and effect.

47.   AUTHORITY TO EXECUTE.

      The parties executing this Lease Agreement hereby warrant and represent
that they are properly authorized to execute this Lease Agreement and bind the
parties on behalf of whom they execute this Lease Agreement and to all of the
terms, covenants and conditions of this Lease Agreement as they relate to the
respective parties hereto.

48.   ASSESSMENT CREDITS.

      The demised property herein may be subject to a special assessment levied
by the City of Redwood City as part of an Improvement District. As a part of
said special assessment proceedings (if any), additional bonds were or may be
sold and assessments were or may be levied to provide for construction
contingencies and reserve funds. Interest shall be earned on such funds created
for contingencies and on reserve funds which will be credited for the benefit of
said assessment district. To the extent surpluses are created in said district
through unused contingency funds, interest earnings or reserve funds, such
surpluses shall be deemed the property of Landlord. Notwithstanding that such
surpluses may be credited on assessments otherwise due against the Leased
Premises, Tenant shall pay to Landlord, as additional rent if, and at the time
of any such credit of surpluses, an amount equal to all such surpluses so
credited. For example: if (i) the property is subject to an annual assessment of
$1,000.00, and (ii) a surplus of $200.00 is credited towards the current year's
assessment which reduces the assessment amount shown on the property tax bill
from $1,000.00 to $800.00, Tenant shall, upon receipt of notice from Landlord,
pay to Landlord said $200.00 credit as Additional Rent.

49.   ASSIGNMENT AND SUBLETTING (CONTINUED).

      A.    In addition to and notwithstanding anything to the contrary in
Paragraph 19 of this Lease and provided Tenant is not in default of this Lease,
Landlord hereby agrees to consent to: (1) Tenant's assigning or subletting said
Lease to: (i) any parent or subsidiary corporation, or corporation with which
Tenant merges or consolidates provided that the net worth of said parent or
subsidiary corporation, or said corporation has a net worth equal to or greater
than the net worth of Tenant (a) at the time of Lease execution or (b) at the
time of such assignment, merger, or consolidation (whichever is greater); or
(ii) any third party or entity to whom Tenant sells all or substantially all of
its assets; provided, that the net worth of the resulting or acquiring
corporation has a net worth after the merger, consolidation or acquisition equal
to or greater than the net worth of Tenant (a) at the time of Lease execution or
(b) at the time of such merger, consolidation or acquisition, whichever is
greater (collectively "Permitted Transfers"); (2) waive its right to terminate
the Lease due to a Permitted Transfer; and (3) waive any rights to Excess Rent
related to a Permitted Transfer. No such assignment or subletting will release
the Tenant from its liability and responsibility under this Lease to the extend
Tenant continues in existence following such transaction. Notwithstanding the
above, Tenant shall be required to (a) give Landlord written notice prior to
such assignment or subletting to any party as described in (i) and (ii) above,
(b) execute Landlord's consent document prepared by Landlord reflecting the



                                      28.
<PAGE>   29

assignment or subletting and (c) pay Landlord's costs for processing said
Consent prior to the effective date of said assignment or sublease.

      B.    Notwithstanding the foregoing, Landlord and Tenant agree that it
shall not be unreasonable for Landlord to refuse to consent to a proposed
assignment, sublease or other transfer ("Proposed Transfer") if the Premises or
any other portion of the Property would become subject to additional or
different Government Requirements as a direct or indirect consequence of the
Proposed Transfer and/or the Proposed Transferee's use and occupancy of the
Premises and the Property. However, Landlord may, in its sole discretion,
consent to such a proposed Transfer where Landlord is indemnified by Tenant and
(i) Subtenant or (ii) Assignee, in form and substance satisfactory to Landlord's
counsel, by Tenant and/or the Proposed Transferee from and against any and all
costs, expenses, obligations and liability arising out of the Proposed Transfer
and/or the Proposed Transferee's use and occupancy of the premises and the
Property.

      C.    Any and all sublease agreement(s) between Tenant and any and all
subtenant(s) (which agreements must be consent to by Landlord, pursuant to the
requirements of this Lease) shall contain the following language:

            "If Landlord and Tenant jointly and voluntarily elect, for any
      reason whatsoever, to terminate the Master Lease prior to the scheduled
      Master Lease termination date, then this Sublease (if then still in
      effect) shall terminate concurrently with the termination of the Master
      Lease. Subtenant expressly acknowledges and agrees that (1) the voluntary
      termination of the Master Lease by Landlord and Tenant and the resulting
      termination of this Sublease shall not give Subtenant any right or power
      to make any legal or equitable claim against Landlord, including without
      limitation any claim for interference with contract or interference with
      prospective economic advantage, and (2) Subtenant hereby waives any and
      all rights it may have under law or at equity against Landlord to
      challenge such an early termination of the Sublease, and unconditionally
      releases and relieves Landlord, and its officers, directors, employees and
      agents, from any and all claims, demands, and/or causes of action
      whatsoever (collectively, "Claims"), whether such matters are known or
      unknown, latent or apparent, suspected or unsuspected, foreseeable or
      unforeseeable, which Subtenant may have arising out of or in connection
      with any such early termination of this Sublease. Subtenant knowingly and
      intentionally waives any and all protection which is or may be given by
      Section 1542 of the California Civil Code which provides as follows: "A
      general release does not extend to claims which the creditor does not know
      or suspect to exist in his favor at the time of executing the release,
      which if known by him must have materially affected his settlement with
      debtor.

            The term of this Sublease is therefore subject to early termination.
      Subtenant's initials here below evidence (a) Subtenant's consideration of
      and agreement to this early termination provision, (b) Subtenant's
      acknowledgment that, in determining the net benefits to be derived by
      Subtenant under the terms of this Sublease, Subtenant has anticipated the
      potential for early termination, and (c) Subtenant's agreement to the
      general waiver and release of Claims above.

50.   BANKRUPTCY AND DEFAULT.

      Paragraph 22 is modified to provide that with respect to non-monetary
defaults not involving Tenant's failure to pay Basic Rent or Additional Rent,
Tenant shall not be in default of any non-monetary obligation if (i) more than
thirty (30) days is required to cure such non-monetary default, and (ii) Tenant
commences cure of such default as soon as reasonably practicable after receiving
written notice of such default from Landlord and thereafter continuously and
with due diligence prosecutes such cure to completion.

51.   ABANDONMENT.

      Paragraph 23 is modified to provide that Tenant shall not be in default
under the Lease if it leaves all or any part of Premises vacant so long as (i)
tenant is performing all of its other obligations under the Lease including the
obligation to pay Basic Rent and Additional Rent (ii) Tenant provides on-site
security during normal business hours for those parts of the Premises left
vacant, (iii) such vacancy does not materially and adversely affect the validity
or coverage of any policy of insurance carried by Landlord with respect to the
Premises, and (iv) the utilities and heating and ventilation system are operated
and maintained to the extent necessary to prevent damage to the Premises or its
systems.

52.   HAZARDOUS MATERIALS.

      Landlord and Tenant agree as follows with respect to the existence or use
of "Hazardous Materials" (as defined herein) on, in, under or about the Premises
and real property located beneath said Premises and the common areas of the
Complex (hereinafter collectively referred to as the "Property"):

      A.    As used herein, the term "Hazardous Materials," shall mean any
material, waste, chemical, mixture or byproduct which is or hereafter is
defined, listed or designated under Environmental Laws (defined below) as a
pollutant, or as a contaminant, or as a toxic or hazardous substance, waste or
material, or any other unwholesome, hazardous, toxic, biohazardous or
radioactive material, waste, chemical, mixture or byproduct or which is listed,
regulated or restricted by any Environmental Law (including, without limitation,
petroleum hydrocarbons or any distillates or derivatives or fractions thereof,
polychlorinated biphenyls or asbestos). As used herein, the term "Environmental
Laws" shall mean any applicable Federal, State of California or local government
law (including common law), statute, regulation, rule, ordinance, permit,
license, order, requirement, agreement or approval, or any determination,
judgment, directive or order of any executive or judicial authority at any level
of Federal, State of California or local government (whether now existing or
subsequently or promulgated) relating to pollution or the protection of the
environment, ecology, natural resources or public health and safety.

      B.    Tenant shall obtain Landlord's written consent, which may be
withheld in Landlord's discretion, prior to the occurrence of any Tenant's
Hazardous Materials Activities (defined below); provided, however, that
Landlord's consent shall not be required for normal use in


                                      30.
<PAGE>   31

compliance with applicable Environmental Laws of customary household and office
supplies (Tenant shall first provide Landlord with a list of said materials
use), such as mild cleaners, lubricants and copier toner. As used herein, the
term "Tenant's Hazardous Materials Activities" shall mean any and all use,
handling, generation, storage, disposal, treatment, transportation, release,
discharge or emission of any Hazardous Materials on, in, beneath, to, from, at
or about the Property, in connection with Tenant's use of the Property, or by
Tenant or by any of Tenant's agents, employees, contractors, vendors, invitees,
visitors or its future subtenants or assignees. Tenant agrees that any and all
Tenant's Hazardous Materials Activities shall be conducted in strict, full
compliance with applicable Environmental Laws at Tenant's expense, and shall not
result in any contamination of the Property or the environment. Tenant agrees to
provide Landlord with prompt written notice of any spill or release of Hazardous
Materials at the Property during the term of the Lease of which Tenant becomes
aware, and further agrees to provide Landlord with prompt written notice of any
violation of Environmental Laws in connection with Tenant's Hazardous Materials
Activities of which Tenant becomes aware. If Tenant's Hazardous Materials
Activities involve Hazardous Materials other than normal use of customary
household and office supplies, Tenant also agrees at Tenant's expense: (i) to
install such Hazardous Materials monitoring, storage and containment devices as
Landlord reasonably deems necessary (Landlord shall have no obligation to
evaluate the need for any such installation or to require any such
installation); (ii) provide Landlord with a written inventory of such Hazardous
Materials, including an update of same each year upon the anniversary date of
the Commencement Date of the Lease ("Anniversary Date"); and (iii) on each
Anniversary Date, to retain a qualified environmental consultant, acceptable to
Landlord, to evaluate whether Tenant is in compliance with all applicable
Environmental Laws with respect to Tenant's Hazardous Materials Activities.
Tenant, at its expense, shall submit to Landlord a report from such
environmental consultant which discusses the environmental consultant's findings
within two (2) months of each Anniversary Date. Tenant, at its expense, shall
promptly undertake and complete any and all steps necessary, and in full
compliance with applicable Environmental Laws, to fully correct any and all
problems or deficiencies in connection with Tenant's Hazardous Materials
Activities identified by the environmental consultant, and promptly provide
Landlord with documentation of all such corrections.

      C.    Prior to termination or expiration of the Lease, Tenant, at its
expense, shall (i) properly remove from the Property all Hazardous Materials
which come to be located at the Property in connection with Tenant's Hazardous
Materials Activities, and (ii) fully comply with and complete all facility
closure requirements of applicable Environmental Laws regarding Tenant's
Hazardous Materials Activities, including but not limited to (x) properly
restoring and repairing the Property to the extent damaged by such closure
activities, and (y) obtaining from the local Fire Department or other
appropriate governmental authority with jurisdiction a written concurrence that
closure has been completed in compliance with applicable Environmental Laws.
Tenant shall promptly provide Landlord with copies of any claims, notices, work
plans, data and reports prepared, received or submitted in connection with any
such closure activities.

      D.    If Landlord, in its sole discretion, believes that the Property has
become contaminated as a result of Tenant's Hazardous Materials Activities,
Landlord in addition to any other rights it may have under this Lease or under
Environmental Laws or other laws, may enter upon the Property and conduct
inspection, sampling and analysis, including but not limited to, obtaining and
analyzing samples of soil and groundwater, for the purpose of determining the
nature and


                                      31.
<PAGE>   32

extent of such contamination. Tenant shall promptly reimburse Landlord for the
costs of such an investigation, including but not limited to, reasonable
attorneys' fees Landlord incurs with respect to such investigation, that
discloses Hazardous Materials contamination for which Tenant is liable under
this Lease. Except as may be required of Tenant by applicable Environmental
Laws, Tenant shall not perform any sampling, testing or drilling to identify the
presence of any Hazardous Materials at the Property, without Landlord's prior
written consent which may be withheld in Landlord's discretion. Tenant shall
promptly provide Landlord with copies of any claims, notices, work plans, data
and reports prepared, received or submitted in connection with any sampling,
testing or drilling performed pursuant to the preceding sentence.

      E.    Tenant shall indemnify, defend (with legal counsel acceptable to
Landlord, whose consent shall not unreasonably be withheld) and hold harmless
Landlord, its employees, assigns, successors, successors-in-interest, agents and
representatives from and against any and all claims (including but not limited
to third party claims from a private party or a government authority),
liabilities, obligations, losses, causes of action, demands, governmental
proceedings or directives, fines, penalties, expenses, costs (including but not
limited to reasonable attorneys', consultants' and other experts' fees and
costs), and damages, which arise from or relate to: (i) Tenant's Hazardous
Materials Activities; (ii) any Hazardous Materials contamination caused by
Tenant prior to the Commencement Date of the Lease; or (iii) the breach of any
obligation of Tenant under this Paragraph 53 (collectively, "Tenant's
Environmental Indemnification"). Tenant's Environmental Indemnification shall
include but is not limited to the obligation to promptly and fully reimburse
Landlord for losses in or reductions to rental income, and diminution in fair
market value of the Property. Tenant's Environmental Indemnification shall
further include but is not limited to the obligation to diligently and properly
implement to completion, at Tenant's expense, any and all environmental
investigation, removal, remediation, monitoring, reporting, closure activities
or other environmental response action (collectively, "Response Actions").
Tenant shall promptly provide Landlord with copies of any claims, notices, work
plans, data and reports prepared, received or submitted in connection with any
Response Actions.

      F.    Landlord hereby informs Tenant, and Tenant hereby acknowledges, that
the Premises and adjacent properties overlie a former solid waste landfill site
commonly known as the Westport Landfill ("Former Landfill"). Landlord further
informs Tenant, and Tenant hereby acknowledges, that (i) prior testing has
detected the presence of low levels of certain volatile and semi-volatile
organic compounds and other contaminants in the groundwater, in the leachate
from the landfilled sold waste, and/or in certain surface waters of the
Property, as more fully described in Section 2.3.2 of the report entitled
"Revised Discharge Monitoring Plan, Westport Landfill Site, Redwood City,
California," prepared by Geomatrix Consultants, dated May 1996 ("Discharge
Plan"), (ii) methane gas is or may be generated by the landfilled solid waste
(item "i" immediately preceding and this item "ii" are hereafter collectively
referred to as the "Landfill Contamination"), and (iii) the Premises and the
Former Landfill are subject to the California Regional Water Quality Control
Board's ("Regional Board") Waste Discharge Requirements Order No. 94-181 (the
"Order"). The Order is attached hereto as EXHIBIT C. As evidenced by their
initials set forth immediately below, Tenant acknowledges that Landlord has
provided Tenant with copies of the environmental reports listed on EXHIBIT D,
and Tenant acknowledges that Tenant and Tenant's experts (if any) have had ample
opportunity to review such reports and


                                      32.
<PAGE>   33

that Tenant has satisfied itself as to the environmental conditions of the
Property and the suitability of such conditions for Tenant's intended use of the
Property.

      G.    Landlord shall indemnify, defend and hold harmless Tenant against
any and all claims asserted by third parties (excluding any agents, employees,
contractors, vendors, invitees, visitors, future subtenants and assignees of
Tenant, and excluding any other parties related to Tenant), including all
liabilities, judgments, damages, suits, orders, government directives, costs and
expenses in connection with such claims, which arise from (i) the Landfill
Contamination, or (ii) the Order, as may be amended ("Landlord's Environmental
Indemnity"); provided, however, that Landlord's Environmental Indemnity shall be
subject to the following limitations and conditions:

            (a)   Landlord's Environmental Indemnity shall not apply to any
economic or consequential damages suffered by Tenant, including but not limited
to loss of business or profits.

            (b)   Landlord's Environmental Indemnity shall not apply, without
limitation, to any releases caused by Tenant's Hazardous Materials Activities.

            (c)   Tenant acknowledges that Landlord must comply with the Order,
as may be amended, and with directives of government authorities including the
Regional Board, with respect to the Contamination and the Former Landfill.
Tenant further acknowledges that groundwater monitoring wells, methane recovery
wells and equipment, and other environmental control devices are located on and
about the Premises and may be modified or added to during the term of the Lease
(collectively, "Environmental Equipment"), and that environmental investigation,
monitoring, closure and post-closure activities (collectively, "Environmental
Activities") will be performed on the Premises during the term of the Lease.
Tenant shall allow Landlord, and any other party named as a discharger under the
Order, as may be amended, and their respective agents, consultants and
contractors, and agents of governmental environmental authorities with
jurisdiction ("Government Representatives") to enter the Premises to access the
Environmental Equipment and to perform Environmental Activities during the term
of the Lease, provided that Tenant's use and occupancy of the Premises shall not
unreasonably be disturbed.

            (d)   Tenant and Landlord shall reasonably cooperate with each other
regarding any Environmental Activities to be performed, and regarding any
Environmental Equipment to be installed, maintained, or removed on the Premises
during the term of the Lease.

            (e)   Tenant shall be responsible at its expense for repairing any
Environmental Equipment damages due to the negligence of Tenant or Tenant's
agents, employees, contractors, vendors, invitees, visitors, future subtenants
or assignees (such terms "invitees" and "visitors" as used in this Paragraph 53
shall not include Landlord or any other party named as a discharger under the
Order as may be amended, or any of their respective agents, consultants or
contractors, or any Government Representatives).


                                      33.
<PAGE>   34

      It is agreed that the Tenant's responsibilities related to Hazardous
Materials will survive the expiration or termination of this Lease and that
Landlord may obtain specific performance of Tenant's responsibilities under this
Paragraph 53.

53.   LEASE TERMS CO-TERMINOUS.

      It is acknowledged that (i) concurrently with the execution of this Lease,
Landlord and Tenant are also executing a second Lease Agreement dated October
26, 1999 (hereinafter referred to as the "Building 19 Lease") affecting adjacent
property located at 3600 Bridge Parkway, Redwood City and (ii) it is the
intention of the parties that the term of this Lease be co-terminous with the
term of the Building 19 Lease such that the terms of both leases expire on the
same date; provided, however, the termination of this Lease resulting from the
terms and conditions stated under Paragraph 19 "Bankruptcy and Default" (subject
to Landlord's option as stated in the respective leases' "Cross Default"
Paragraph) or Paragraph 21 "Destruction" or Paragraph 22 "Eminent Domain" shall
not result in a termination of the Building 19 Lease, unless Landlord elects, at
its sole and absolute discretion, to terminate both of the leases.

54.   CROSS DEFAULT.

      As a material part of the consideration for the execution of this Lease by
Landlord, it is agreed between Landlord and Tenant that a default under this
Lease, or a default under said Building 19 Lease may, at the option of Landlord,
be considered a default under both leases, in which event Landlord shall be
entitled (but in no event required) to apply all rights and remedies of Landlord
under the terms of one lease to both leases including, but not limited to, the
right to terminate one or both of said leases by reason of a default under said
Building 19 Lease or hereunder.

55.   ADDITIONAL RENT CONTINUED.

      The following items shall be excluded from "Additional Rent":

      A.    Leasing commissions, attorney's fees, costs, disbursements, and
other expenses incurred in connection with negotiations with other tenants, or
disputes between Landlord and other third party not related to Tenant
(hereinafter referred to as "Third Party"), or in connection with marketing,
leasing, renovating, or improving space for other current or prospective tenants
or other current or prospective occupants of the Complex; notwithstanding
anything to the contrary herein, any costs and expenses Landlord is entitled to
be reimbursed for as stated under Paragraph 22 ("Bankruptcy and Default") ARE
NOT excluded Additional Rent items as reflected in this Paragraph 56.

      B.    The cost of any service sold to any other Third Party or other
occupant whose leased premises are not part of the Premises leased herein and
for which Landlord is entitled to be reimbursed as an additional charge or
rental over and above the basic rent and additional rent payable under the lease
agreement with said other tenant.

      C.    Any costs, fines, or penalties incurred due to violations by
Landlord of any governmental rule or authority, provided Tenant is not
responsible under the Lease for such


                                      34.
<PAGE>   35

costs, fines and/or penalties, and/or provided Tenant's actions or inactions did
not cause, in whole or in part, such costs, fines and/or penalties.

      D.    Wages, salaries, or other compensation paid to executive employees
above the grade of Property Manager.

      E.    Repairs or other work occasioned by fire, windstorm, or other
insured peril, to the extent that Landlord shall receive proceeds of such
insurance or would have received such proceeds had Landlord maintained the
insurance coverage required under this Lease providing said insurance coverage
was available and Tenant paid its share of the premium as required under the
Lease and any insurance deductible(s) which Tenant is responsible for paying and
provided Tenant is not responsible for the damage to the Premises.

56.   SECURITY DEPOSIT IN THE FORM OF AN IRREVOCABLE STANDBY LETTER OF CREDIT.

      The cash Security Deposit provided for in Paragraph 4G of the Lease shall
be deposited by Tenant with Landlord upon execution of this Lease; however,
Tenant shall have the right, at Tenant's sole election, to replace one-half
($246,758.40) of the cash Security Deposit held by Landlord with an irrevocable
letter of credit, drawn upon an institutional lender reasonably acceptable and
accessible to Landlord in form and content reasonably satisfactory to Landlord
and for a term equal to the Term of this Lease plus a period of sixty (60) days,
and said irrevocable letter of credit shall not be subject to annual renewal.
Said financial institution must agree that the presentment for demand may be
made in San Jose, Santa Clara or Palo Alto, California. One half of the cash
Security Deposit ($246,758.40) held by Landlord shall be refunded to Tenant upon
Landlord's receipt of an acceptable irrevocable letter of credit. If Tenant
defaults with respect to any provisions of this Lease, including but not limited
to provisions relating to the payment of Rent, Landlord may (but shall not be
required to) draw down on the irrevocable letter of credit for payment of any
sum which Landlord may spend or become obligated to spend by reason of Tenant's
default, or to compensate Landlord for any loss or damage which Landlord may
suffer by reason of Tenant's default. Landlord and Tenant acknowledge that such
irrevocable letter of credit will be treated as if it were a cash Security
Deposit, and such irrevocable letter of credit may be drawn down upon by
Landlord upon demand and presentation of evidence of the identity of Landlord to
the issuing bank, in the event that Tenant defaults with respect to any
provision of this Lease and such default is not cured within any applicable cure
period. Landlord acknowledges that it is not entitled to draw down such
irrevocable letter of credit unless Landlord would have been entitled to draw
upon a cash Security Deposit pursuant to the terms of Paragraph 4G of the Lease.
Concurrently with the delivery of the required information to the issuing bank,
Landlord shall deliver to Tenant written evidence of the default upon which the
draw down was based, together with evidence that Landlord has provided to Tenant
the written notice of such default which was required under the applicable
provision of the Lease, and evidence of the failure of Tenant to cure such
default


                                      35.
<PAGE>   36

within the applicable grace period following receipt of such notice of default.
If any portion of the irrevocable letter of credit is used or applied pursuant
hereto, Tenant shall, within ten (10) days after receipt of a written demand
therefor from Landlord, restore and replace the value of such security by either
(i) depositing cash with Landlord in the amount equal to the sum drawn down
under the irrevocable letter of credit, or (ii) increasing the irrevocable
letter of credit to its value immediately prior to such application. Tenant's
failure to replace the value of the security as provided in the preceding
sentence shall be a material breach of its obligation under this Lease.

57.   ASSIGNMENT OF WARRANTIES.

      During the Term of the Lease, Landlord hereby assigns to Tenant all of
Landlord's Contractor's warranties and shall cooperate with Tenant in enforcing
any of such warranties except that Landlord shall not be required to pay any
legal fees or incur any expenses in this regard.

58.   BROKERS.

      Landlord and Tenant each represent to the other that they have dealt with
no real estate brokers, agents, or finders in connection with this transaction,
except as follows: Cornish & Carey Oncor International ("C&C"), whose commission
shall be paid by Landlord in accordance with Landlord's standard commission
schedule which commission for this Lease is a total of $100,000.00. Each party
agrees to defend, protect, indemnify and hold the other party harmless from and
against all claims for brokerage commissions, finder's fees, and other
compensation made by any broker, agent, or finder as consequence of the
indemnifying party's actions or dealing with such broker, agent or finder. The
parties hereto acknowledge that Landlord will not pay an additional brokerage
fee to C&C or any broker in the event the term of this Lease is extended for any
reason whatsoever.

existing sublease or subtenancies or operate as an assignment to Landlord of all
or any such subleases or subtenancies.

9. ALTERATIONS AND ADDITIONS.

        Tenant shall not make, or suffer to be made, any alteration or addition
to the Premises, or any part thereof, without the written consent of Landlord
(which written consent (i) shall not be unreasonably withheld and (ii) will
specify whether Landlord shall require removal of said alterations and/or
additions, provided Tenant requests such determination from Landlord), first had
and obtained by Tenant, but at the cost of Tenant, and any addition to, or
alteration of, the Premises, except moveable furniture and trade fixtures, shall
at once become a part of the Premises and belong to Landlord. Landlord reserves
the right to approve all contractors and mechanics proposed by Tenant to make
such alterations and additions. Tenant shall retain title to all moveable
furniture and trade fixtures placed in the Premises. All heating, lighting,
electrical, air-conditioning, floor to ceiling partitioning, drapery, carpeting,
and floor installations made by Tenant, together with all property that has
become an integral part of the Premises, shall not be deemed trade floor to
ceiling fixtures. Tenant agrees that it will not proceed to make such alteration
or additions, without having obtained consent from Landlord to do so, and until
five (5) days from the receipt of such consent, in order that Landlord may post
appropriate notices to avoid any liability to contractors or material suppliers
for payment for Tenant's improvements. Tenant will at all times permit such
notices to be posted and to remain posted until the completion of work. Tenant
shall, if required by Landlord, secure at Tenant's own cost and expense, a
completion and lien indemnity bond, satisfactory to Landlord, for such work.
Tenant further covenants and agrees that any mechanic's lien filed against the
Premises or against the Complex for work claimed to have been done for, or
materials claimed to have been furnished to Tenant, will be discharged by
Tenant, by bond or otherwise, within ten (10) days after the filing thereof, at
the cost and expense of Tenant. Any exceptions to the foregoing must be made in
writing and executed by both Landlord and Tenant. Notwithstanding anything to
the contrary herein, under no circumstances shall Tenant be authorized to
penetrate the soil to a depth that exceeds three and one-half feet from the
uppermost surface of the soil.

10. TENANT MAINTENANCE.

        Tenant shall, at its sole cost and expense, keep and maintain the
Premises (including appurtenances) and every part thereof in a high standard of
maintenance and repair, and in good and sanitary condition. Tenant's maintenance
and repair responsibilities herein referred to include, but are not limited to,
all windows, window frames, plate glass, glazing, truck doors, plumbing systems
(such as water and drain lines, sinks, toilets, faucets, drains, showers and
water fountains), electrical systems (such as panels, conduits, outlets,
lighting fixtures, lamps, bulbs, tubes, ballasts), heating and air-conditioning
systems (such as compressors, fans, air handlers, ducts, mixing boxes,
thermostats, time clocks, boilers, heaters, supply and return grills), store
fronts, roofs, downspouts, all interior improvements within the premises
including but not limited to wall coverings, window coverings, carpet, floor
coverings, partitioning, ceilings, doors (both interior and exterior, including
closing mechanisms, latches, locks, skylights (if any), automatic fire
extinguishing systems, and elevators and all other interior improvements of any
nature whatsoever. Tenant agrees to provide carpet shields under all rolling
chairs or to otherwise be responsible for wear and tear of the carpet caused by
such rolling chairs if such wear and tear exceeds that caused by normal foot
traffic in surrounding areas. Areas of excessive wear shall be replaced at
Tenant's sole expense upon Lease termination. Tenant hereby waives all rights
under, and benefits of, subsection 1 of Section 1932 and Section 1941 of the
California Civil Code and under any similar law, statute or ordinance now or
hereafter in effect.

11. UTILITIES.

        Tenant shall pay promptly, as the same become due, all charges for
water, gas, electricity, telephone, telex and other electronic communications
service, sewer service, waste pick-up and any other utilities, materials or
services furnished directly to or used by Tenant on or about the Premises during
the term of this Lease, including, without limitation, any temporary or
permanent utility surcharge or other exactions whether or not hereinafter
imposed.

        Landlord shall not be liable for and Tenant shall not be entitled to any
abatement or reduction of rent by reason of any interruption or failure of
utility services to the Premises when such interruption or failure is caused by
accident, breakage, repair, strikes, lockouts, or other labor disturbances or
labor disputes of any nature, or by any other cause, similar or dissimilar,
beyond the reasonable control of Landlord.

12. TAXES.

        A. As Additional Rent and in accordance with Paragraph 4D of this Lease,
Tenant shall pay to Landlord Tenant's proportionate share of all Real Property
Taxes, which prorata share shall be allocated to the leased Premises by square
footage or other equitable basis, as calculated by Landlord. The term "Real
Property Taxes", as used herein, shall mean (i) all taxes, assessments, levies
and other charges of any kind or nature whatsoever, general and special,
foreseen and unforeseen (including all installments of principal and interest
required to pay any general or special assessments for public improvements and
any increases resulting from reassessment caused by any change in ownership of
the Complex) now or hereafter imposed by any governmental or quasi-governmental
authority or special district having the direct or indirect



                                       9.
<PAGE>   47

power to tax or levy assessments, which are levied or assessed against, or with
respect to the value, occupancy or use of, all or any portion of the Complex (as
now constructed or as may at any time hereafter be constructed, altered, or
otherwise changed) or Landlord's interest therein; any improvements located
within the Complex (regardless of ownership); the fixtures, equipment and other
property of Landlord, real or personal, that are an integral part of and located
in the Complex; or parking areas, public utilities, or energy within the
Complex; (ii) all charges, levies or fees imposed by reason of environmental
regulation or other governmental control of the Complex; and (iii) all costs and
fees (including attorneys' fees) incurred by Landlord in contesting any Real
Property Tax and in negotiating with public authorities as to any Real Property
Tax. If at any time during the term of this Lease the taxation or assessment of
the Complex prevailing as of the commencement date of this Lease shall be
altered so that in lieu of or in addition to any Real Property Tax described
above there shall be levied, assessed or imposed (whether by reason of a change
in the method of taxation or assessment, creation of a new tax or charge, or any
other cause) an alternate or additional tax or charge (i) on the value, use or
occupancy of the Complex or Landlord's interest therein or (ii) on or measured
by the gross receipts, income or rentals from the Complex, on Landlord's
business on leasing the Complex, or computed in any manner with respect to the
operation of the Complex, then any such tax or charge, however designated, shall
be included within the meaning of the term "Real Property Taxes" for purposes of
this Lease. If any Real Property Tax is based upon property or rents unrelated
to the Complex, then only that part of such real Property Tax that is fairly
allocable to the Complex shall be included within the meaning of the term "Real
Property Taxes". Notwithstanding the foregoing, the term "Real Property Taxes"
shall not include estate, inheritance, gift or franchise taxes of Landlord or
the federal or state net income tax imposed on Landlord's income from all
sources. The term "Real Estate Taxes" shall also include supplemental taxes
related to the period of Tenant's Lease Term whenever levied, including any such
taxes that may be levied after the Lease Term has expired.

        B. TAXES ON TENANT'S PROPERTY

             (a) Tenant shall be liable for and shall pay ten (10) days before
delinquency, taxes levied against any personal property or trade fixtures placed
by Tenant in or about the Premises. If any such taxes on Tenant's personal
property or trade fixtures are levied against Landlord or Landlord's property or
if the assessed value of the Premises is increased by the inclusion therein of a
value placed upon such personal property or trade fixtures of Tenant and if
Landlord, after written notice to Tenant, pays the taxes based on such increased
assessment, which Landlord shall have the right to do regardless of the validity
thereof, but only under proper protest if requested by Tenant, Tenant shall upon
demand, as the case may be, repay to Landlord the taxes so levied against
Landlord, or the proportion of such taxes resulting from such increase in the
assessment; provided that in any such event Tenant shall have the right, in the
name of Landlord and with Landlord's full cooperation, to bring suit in any
court of competent jurisdiction to recover the amount of any such taxes so paid
under protest, and any amount so recovered shall belong to Tenant.

             (b) if the Tenant improvements in the Premises, whether installed,
and/or paid for by Landlord or Tenant and whether or not affixed to the real
property so as to become a part thereof, are assessed for real property tax
purposes at a valuation higher than the valuation at which standard office
improvements in other space in the Complex are assessed, then the real



                                      10.
<PAGE>   48

property taxes and assessments levied against Landlord or the Complex by reason
of such assessed valuation shall be deemed to be taxes levied against personal
property of Tenant and shall be governed by the provisions of 12B(a) above. If
the records of the County Assessor are available and sufficiently detailed to
serve as a basis for determining whether said Tenant improvements are assessed
at a higher valuation than standard office improvements in other space in the
Complex, such records shall be binding on both the Landlord and the Tenant. If
the records of the County Assessor are not available or sufficiently detailed to
serve as a basis for making said determination, the actual cost of construction
shall be used.

13. LIABILITY INSURANCE.

        Tenant, at Tenant's expense, agrees to keep in force during the term of
this Lease a policy of commercial general liability insurance with a combined
single limit coverage of not less than Two Million Dollars ($2,000,000) per
occurrence for injuries to or death of persons occurring in, on or about the
Premises or the Complex, and property damage insurance with limits of $500,000.
The policy or policies affecting such insurance, certificate of insurance of
which shall be furnished to Landlord, shall name Landlord as additional
insureds, and shall inure any liability of Landlord, contingent or otherwise, as
respects acts or omissions of Tenant, its agents, employees or invitees or
otherwise by any conduct or transactions of any of said persons in or about or
concerning the Premises, including any failure of Tenants to observe or perform
any of its obligations hereunder; shall be issued by an insurance company
admitted to transact business in the State of California; and shall provide that
the insurance effected thereby shall not be canceled, except upon thirty (30)
days' prior written notice to Landlord. If, during the term of this Lease, in
the considered opinion of Landlord's Lender, insurance advisor, or counsel, the
amount of insurance described in this paragraph 13 is not adequate, Tenant
agrees to increase said coverage to such reasonable amount as Landlord's Lender,
insurance advisor, or counsel shall deem adequate.

14. TENANT'S PERSONAL PROPERTY INSURANCE AND WORKMAN'S COMPENSATION INSURANCE.

        Tenant shall maintain a policy or policies of fire and property damage
insurance in "all risk" form with a sprinkler leakage endorsement insuring the
personal property, inventory, trade fixtures, and leasehold improvements within
the leased Premises for the full replacement value thereof. The proceeds from
any of such policies shall be used for the repair or replacement of such items
so insured.

        Tenant shall also maintain a policy or policies of workman's
compensation insurance and any other employee benefit insurance sufficient to
comply with all laws.

15. PROPERTY INSURANCE.

        Landlord shall purchase and keep in force and as Additional Rent and in
accordance with Paragraph 4D of this Lease, Tenant shall pay to Landlord (or
Landlord's agent if so directed by Landlord) Tenant's proportionate share
(calculated on a square footage or other equitable basis as calculated by
Landlord) of the deductibles on insurance claims and the cost of policy or
policies of insurance covering loss or damage to the Premises and Complex in the
amount of the



                                      11.
<PAGE>   49

full replacement value thereof, providing protection against those perils
included within the classification of "all risks" insurance and flood and/or
earthquake insurance, if available, plus a policy of rental income insurance in
the amount of one hundred (100%) percent of twelve (12) months Basic Rent, plus
sums paid as Additional Rent and any deductibles related thereto. If such
insurance cost is increased due to Tenant's use of the Premises or the Complex,
Tenant agrees to pay to Landlord the full cost of such increase. Tenant shall
have no interest in nor any right to the proceeds of any insurance procured by
Landlord for the Complex.

        Landlord and Tenant do each hereby respectively release the other, to
the extent of insurance coverage of the releasing party, from any liability for
loss or damage caused by fire or any of the extended coverage casualties
included in the releasing party's insurance policies, irrespective of the cause
of such fire or casualty; provided, however, that if the insurance policy of
either releasing party prohibits such waiver, then this waiver shall not take
effect until consent to such waiver is obtained. If such waiver is so
prohibited, the insured party affected shall promptly notify the other party
thereof.

16. INDEMNIFICATION.

        Landlord shall not be liable to Tenant and Tenant hereby waives all
claims against Landlord for any injury to or death of any person or damage to or
destruction of property in or about the Premises or the Complex by or from any
cause whatsoever, including, without limitation, gas, fire, oil, electricity or
leakage of any character from the roof, walls, basement or other portion of the
Premises or the Complex but excluding, however, the willful misconduct or
negligence of Landlord, its agents, servants, employees, invitees, or
contractors of which negligence Landlord has knowledge and reasonable time to
correct. Except as to injury to persons or damage to property to the extent
arising from the willful misconduct or the negligence of Landlord, its agents
servants, employees, invitees, or contractors. Tenant shall hold Landlord
harmless from and defend Landlord against any and all expenses, including
reasonable attorneys' fees, in connection therewith, arising out of any injury t
or death of any person or damage to or destruction of property occurring in, on
or about the Premises, or any part thereof, from any cause whatsoever.

17. COMPLIANCE.

        Tenant, at its sole cost and expense, shall promptly comply with all
laws, statutes, ordinances and governmental rules, regulations or requirements
now or hereafter in effect; with the requirements of any board of fire
underwriters or other similar body now or hereafter constituted; and with any
direction or occupancy certificate issued pursuant to law by any public officer;
provided, however, that no such failure shall be deemed a breach of the
provisions if Tenant, immediately upon notification, commences to remedy or
rectify said failure. The judgment of any court of competent jurisdiction or the
admission of Tenant in any action against Tenant, whether Landlord be a party
thereto or not, that Tenant has violated any such law, statute, ordinance or
governmental rule, regulation, requirement, direction or provision, shall be
conclusive of that fact as between Landlord and Tenant. This paragraph shall not
be interpreted as requiring Tenant to make structural changes or improvements,
except to the extent such changes or improvements are required as a result of
Tenant's use of the Premises. Tenant shall, at its sole cost and expense, comply
with any and all requirements pertaining to said Premises, or



                                      12.
<PAGE>   50

any insurance organization or company, necessary for the maintenance of
reasonable fire and public liability insurance covering the Premises.

18. LIENS.

        Tenant shall keep the Premises and the Complex free from any liens
arising out of any work performed, materials furnished or obligation incurred by
Tenant. In the event that Tenant shall not, within ten (10) days following the
imposition of such lien, cause the same to be released of record, Landlord shall
have, in addition to all other remedies provided herein and by law, the right,
but no obligation, to cause the same to be released by such means as it shall
deem proper, including payment of the claim giving rise to such lien. All sums
paid by Landlord for such purpose, and all expenses incurred by it in connection
therewith, shall be payable to Landlord by Tenant on demand with interest at the
prime rate of interest as quoted by the Bank of America.

19. ASSIGNMENT AND SUBLETTING.

        Tenant shall not assign, transfer, or hypothecate the leasehold estate
under this Lease, or any interest therein, and shall not sublet the Premises, or
any part thereof, or any right or privilege appurtenant thereto, or suffer any
other person or entity to occupy or use the Premises, or any portion thereof,
without, in each case, the prior written consent of Landlord which consent will
not be unreasonably withheld. As a condition for granting this consent to any
assignment, transfer, or subletting, Landlord shall require Tenant to pay to
Landlord, as Additional Rent, seventy-five (75%) percent of all rents and/or
additional consideration due Tenant from its assignees, transferees, or
subtenants in excess of the Rent payable by Tenant to Landlord hereunder for the
assigned, transferred and/or subleased space ("Excess Rent"); provided, however,
that before sharing such Excess Rent, Tenant shall first be entitled to recover
from such Excess Rent the amount of any reasonable leasing commissions related
to said transaction paid by Tenant to third party brokers not affiliated with
Tenant. Tenant shall, by thirty (30) days written notice, advise Landlord of its
intent to assign or transfer Tenant's interest in the Lease or sublet the
Premises or any portion thereof for any part of the term hereof. Within thirty
(30) days after receipt of said written notice, Landlord may, in its sole
discretion, elect to terminate this Lease as to the portion of the Premises
described in Tenant's notice on the date specified in Tenant's notice by giving
written notice of such election to terminate. If no such notice to terminate is
given to Tenant within said thirty (30) day period, Tenant may proceed to locate
an acceptable sublease, assignee, or other transferee for presentment to
Landlord for Landlord's approval, all in accordance with the terms, covenants,
and conditions of this paragraph 19. If Tenant intends to sublet the entire
Premises and Landlord elects to terminate this Lease, this Lease shall be
terminated on the date specified in Tenant's notice. If, however, this Lease
shall be terminated on the date specified in Tenant's notice. If, however, this
Lease shall terminate pursuant to the foregoing with respect to less than all
the Premises, the rent, as defined and reserved hereinabove shall be adjusted on
a pro rata basis to the number of square feet retained by Tenant, and this Lease
as so amended shall continue in full force and effect. In the event Tenant is
allowed to assign, transfer or sublet the whole or any part of the Premises,
with the prior written consent of Landlord, no assignee, transferee or subtenant
shall assign or transfer this Lease, either in whole or in art, or sublet the
whole or any part of the Premises, without also having obtained the prior
written consent of Landlord. A consent of Landlord to one assignment,



                                      13.
<PAGE>   51

transfer, hypothecation, subletting, occupation or use by any other person shall
not release Tenant from any of Tenant's obligations hereunder or be deemed to be
a consent to any subsequent similar or dissimilar assignment, transfer,
hypothecation, subletting, occupation or use by any other person. Any such
assignment, transfer, hypothecation, subletting, occupation or use without such
consent shall be void and shall constitute a breach of this Lease by Tenant and
shall, at the option of Landlord exercised by written notice to Tenant,
terminate this Lease. The leasehold estate under this Lease shall not, nor shall
any interest therein, be assignable for any purpose by operation of law without
the written consent of Landlord. As a condition to its consent, Landlord shall
require Tenant to pay all expenses in connection with the assignment, and
Landlord shall require Tenant's assignee or transferee (or other assignees or
transferees) to assume in writing all of the obligations under this Lease and
for Tenant to remain liable to Landlord under the Lease. Notwithstanding the
above, in no event will Landlord consent to sub-sublease.

20. SUBORDINATION AND MORTGAGES.

        In the event Landlord's title or leasehold interest is now or hereafter
encumbered b a deed of trust, upon the interest of Landlord in the land and
buildings in which the demised Premises are located, to secure a loan from a
lender (hereinafter referred to as "Lender") to Landlord, Tenant shall, at the
request of Landlord or Lender, execute in writing an agreement subordinating its
rights under this Lease to the lien of such deed of trust, or, if so required,
agreeing that the lien of Lender's deed of trust shall be or remain subject and
subordinate to the rights of Tenant under this Lease. Notwithstanding any such
subordination, Tenant's possession under this Lease shall not be disturbed if
Tenant is not in default and so long as Tenant shall pay all rent and observe
and perform all of the provisions set forth in this Lease.

21. ENTRY BY LANDLORD.

        Landlord reserves, and shall at all reasonable times after at least 24
hours notice (except in emergencies) have, the right to enter the Premises to
inspect them; to perform any services to be provided by Landlord hereunder, to
submit the Premises o prospective purchasers, mortgagers or tenants; to post
notices of nonresponsibility; and to alter, improve or repair the Premises and
any portion of the Complex, all without abatement of rent; and may erect
scaffolding and other necessary structures in or through the Premises where
reasonably required by the character of the work to be performed; provided,
however that the business of Tenant shall be interfered with to the least extent
that is reasonably practical. For each of the foregoing purposes, Landlord shall
at all times have and retain a key with which to unlock all of the doors in an
emergency in order to obtain entry to the Premises, and any entry to the
Premises obtained by Landlord and by any of said means, or otherwise, shall not
under any circumstances be construed or deemed to be a forcible or unlawful
entry into or a detainer of the Premises or an eviction, actual or constructive,
of Tenant from the Premises or any potion thereof. Landlord shall also have the
right at any time to change the arrangement or location of entrances or
passageways, doors and doorways, and corridors, elevators, stairs, toilets or
other public parts of the Complex and to change the name, number or designation
by which the Complex is commonly known, and none of the foregoing shall be
deemed an actual or constructive eviction of Tenant, or shall entitle Tenant to
any reduction of rent hereunder.



                                      14.
<PAGE>   52

22. BANKRUPTCY AND DEFAULT.

        The commencement of a bankruptcy action or liquidation action or
reorganization action or insolvency action or an assignment of or by Tenant for
the benefit of creditors, or any similar action undertaken by Tenant, or the
insolvency of Tenant, shall, at Landlord's option, constitute a breach of this
Lease by Tenant. If the trustee or receiver appointed to serve during a
bankruptcy, liquidation, reorganization, insolvency or similar action elects to
reject Tenant's unexpired Lease, the trustee or receiver shall notify Landlord
in writing of its election within thirty (30) days after an order for relief in
a liquidation action or within thirty (30) days after the commencement of any
action.

        Within thirty (30) days after court approval of the assumption of this
Lease, the trustee or receiver shall cure (or provide adequate assurance to the
reasonable satisfaction of Landlord that the trustee or receiver shall cure) any
and all previous defaults under the unexpired Lease and shall compensate
Landlord for all actual pecuniary loss and shall provide adequate assurance of
future performance under said Lease to the reasonable satisfaction of Landlord.
Adequate assurance of future performance, as used herein, includes, but shall
not be limited to: (i) assurance of source and payment of rent, and other
consideration due under this Lease; (ii) assurance that the assumption or
assignment of this Lease will not breach substantially any provision, such as
radius, location, use, or exclusivity provision, in any agreement relating to
the above described Premises.

        Nothing contained in this section shall affect the existing right of
Landlord to refuse to accept an assignment upon commencement of or in connection
with a bankruptcy, liquidation, reorganization or insolvency action or an
assignment of Tenant for the benefit of creditors or other similar act. Nothing
contained in this Lease shall be construed as giving or granting or creating an
equity in the demised Premises to Tenant. In no event shall the leasehold estate
under this Lease, or any interest therein, be assigned by voluntary or
involuntary bankruptcy proceeding without the prior written consent of Landlord.
In no event shall this Lease or any rights or privileges hereunder be an asset
of Tenant under any bankruptcy, insolvency or reorganization proceedings.

        The failure to perform or honor any covenant, condition or
representation made under this Lease shall constitute a default hereunder by
Tenant upon expiration of the appropriate grace period hereinafter provided.
Tenant shall have a period of five (5) days from the date of written notice from
Landlord within which to cure any default in the payment of rental or adjustment
thereto. Tenant shall have a period of thirty (30) days from the date of written
notice from Landlord within which to cur any other default under this Lease;
provided, however, that if the nature of Tenant's failure is such that more than
thirty (30) days is reasonably required to cure the same, Tenant shall not be in
default so long as Tenant commences performance within such thirty (30) day
period and thereafter prosecutes the same to completion. Upon an uncured default
of this Lease by Tenant, Landlord shall have the following rights and remedies
in addition to any other rights or remedies available to Landlord at law or in
equity:

             (a) The rights and remedies provided for by California Civil Code
Section 1951.2, including but not limited to, recovery of the worth at the time
of award of the amount by which the unpaid rent for the balance of the term
after the time of award exceeds the amount of



                                      15.
<PAGE>   53

rental loss for the same period that Tenant proves could be reasonably avoided,
as computed pursuant to subsection (b) of said Section 1951.2. Any proof by
Tenant under subparagraphs (2) and (3) of Section 1951.2 of the California Civil
Code of the amount of rental loss that could be reasonably avoided shall be made
in the following manner: Landlord and Tenant shall each select a licensed real
estate broker in the business of renting property of the same type and use as
the Premises and in the same geographic vicinity. Such two real estate brokers
shall select a third licensed real estate broker, and the three licensed real
estate brokers so selected shall determine the amount of the rental loss that
could be reasonably avoided from the balance of the term of this Lease after the
time of award. The decision of the majority of said licensed real estate brokers
shall be final and binding upon the parties hereto.

             (b) The rights and remedies provided by California Civil Code
Section which allows Landlord to continue the Lease in effect and to enforce all
of its rights and remedies under this Lease, including the right to recover rent
as it becomes due, for so long as Landlord does not terminate Tenant's right to
possession; acts of maintenance or preservation, efforts to relet the Premises,
or the appointment of a receiver upon Landlord's initiative to protect its
interest under this Lease shall not constitute a termination of Tenant's right
to possession.

             (c) The right to terminate this Lease by giving notice to Tenant in
accordance with applicable law.

             (d) To the extent permitted by law the right and power, to enter
the Premises and remove therefrom all persons and property, to store such
property in a public warehouse or elsewhere at the cost of and for the account
of Tenant, and to sell such property and apply such proceeds therefrom pursuant
to applicable California law, Landlord may from time to time sublet the Premises
or any part thereof for such term or terms (which may extend beyond the term of
this Lease) and at such rent and such other terms as Landlord in its sole
discretion may deem advisable, with the right to make alterations and repairs to
the Premises. Upon each subletting, (i) Tenant shall be immediately liable to
pay Landlord, in addition to indebtedness other than rent due hereunder, the
cost of such subletting, including, but not limited to, reasonable attorneys'
fees, and any real estate commissions actually paid, and the cost of such
alterations and repairs incurred by Landlord and the amount, if any, by which
the rent hereunder for the period of such subletting (to the extent such period
does not exceed the term hereof) exceeds the amount to be paid as rent for the
Premises for such period or (ii) at the option of Landlord, rents received from
such subletting shall be applied first to payment to indebtedness other than
rent due hereunder from Tenant to Landlord; second, to the payment of any costs
of such subletting and of such alterations and repairs; third, to payment of
rent due and unpaid hereunder; and the residue, if any, shall be held by
Landlord and applied in payment of future rent as the same becomes due
hereunder. If Tenant has been credited with any rent to be received by such
subletting under option (i) and such rent shall not be promptly paid to Landlord
by the subtenant(s), or if such rentals received from such subletting under
option (ii) during any month be less than that to be paid during that month by
Tenant hereunder, Tenant shall pay any such deficiency to Landlord. Such
deficiency shall be calculated and paid monthly. No taking possession of the
Premises by Landlord, shall be construed as an election on its part to terminate
this Lease unless a written notice of such intention be given to Tenant.
Notwithstanding any such subletting without termination, Landlord may at any
time hereafter elect to terminate this Lease for such previous breach.



                                      16.
<PAGE>   54

             (e) The right to have a receiver appointed for Tenant upon
application by Landlord, to take possession of the Premises and to apply any
rental collected from the Premises and to exercise all other rights and remedies
granted to Landlord pursuant to subparagraph d. above.

23. ABANDONMENT.

        Tenant shall not vacate or abandon the Premises at any time during the
term of this Lease, and if Tenant shall abandon, vacate or surrender said
Premises, or be dispossessed by the process of law, or otherwise, any personal
property belonging to Tenant and left on the Premises shall be deemed to be
abandoned, at the option of Landlord, except such property as may be mortgaged
to Landlord.

24. DESTRUCTION.

        In the event the Premises are destroyed in whole or in part from any
cause, except for routine maintenance and repairs and incidental damage and
destruction caused from vandalism and accidents for which Tenant is responsible
for under Paragraph 10, Landlord may, at its option:

        A. Rebuild or restore the Premises to their condition prior to the
damage or destruction, or

        B. Terminate this Lease (providing that the Premises is damaged to the
extent of 33 1/3% of the replacement cost).

        If Landlord does not give Tenant notice in writing within thirty (30)
days from the destruction of the Premises of its election to either rebuild and
restore them, or to terminate this Lease, Landlord shall be deemed to have
elected to rebuild or restore them, in which event Landlord agrees, at its
expense, promptly to rebuild or restore the Premises to their condition prior to
the damage or destruction. Tenant shall be entitled to a reduction in rent while
such repair is being made in the proportion that the area of the Premises
rendered untenantable by such damage bears to the total area of the Premises. If
Landlord initially estimates that the rebuilding or restoration will exceed one
hundred eighty (180) days or if Landlord does not complete the rebuilding or
restoration within one hundred eighty (180) days following the date of
destruction (such period of time to be extended for delays caused by the fault
or neglect of Tenant or because of Acts of God, acts of public agencies, labor
disputes, strikes, fires, freight embargoes, rainy or stormy weather, inability
to obtain materials, supplies or fuels, acts of contractors or subcontractors,
or delay of the contractors or subcontractors due to such causes or other
contingencies beyond the control of Landlord), then Tenant shall have the right
to terminate this Lease by giving fifteen (15) days prior written notice to
Landlord. Notwithstanding anything herein to the contrary, Landlord's obligation
to rebuild or restore shall be limited to the building and interior improvements
constructed by Landlord as they existed as of the commencement date of the Lease
and shall not include restoration of Tenant's trade fixtures, equipment,
merchandise, or any improvements, alterations or additions made by Tenant to the
Premises, which Tenant shall forthwith replace or fully repair at Tenant's sole
cost and expense provided this Lease is not cancelled according to the
provisions above.



                                      17.
<PAGE>   55

        Unless this Lease is terminated pursuant to the foregoing provisions,
this Lease shall remain in full force and effect. Tenant hereby expressly waives
the provisions of Section 1932, Subdivision 2, in Section 1933, Subdivision 4 of
the California Civil Code.

        In the event that the building in which the Premises are situated is
damaged or destroyed to the extent of not less than 33 1/3% of the replacement
cost thereof, Landlord may elect to terminate this Lease, whether the Premises
be injured or not. Notwithstanding anything to the contrary herein, Landlord may
terminate this Lease in the event of an uninsured event or if insurance proceeds
are insufficient to cover one hundred percent of the rebuilding costs net of the
deductible.

25. EMINENT DOMAIN.

        If all or any part of the Premises shall be taken by any public or
quasi-public authority under the power of eminent domain or conveyance in lieu
thereof, this Lease shall terminate as to any portion of the Premises so taken
or conveyed on the date when title vests in the condemnor, and Landlord shall be
entitled to any and all payment, income, rent, award, or any interest therein
whatsoever which may be paid or made in connection with such taking or
conveyance, and Tenant shall have no claim against Landlord or otherwise for the
value of any unexpired term of this Lease. Notwithstanding the foregoing
paragraph, any compensation specifically awarded Tenant for loss of business,
Tenant's personal property, moving cost or loss of goodwill, shall be and remain
the property of Tenant.

        If (i) any action or proceeding is commenced for such taking of the
Premises or any part thereof, or if Landlord is advised in writing by any entity
or body having the right or power of condemnation of its intention to condemn
the premises or any portion thereof, or (ii) any of the foregoing events occur
with respect to the taking of any space in the Complex not leased hereby, or if
any such spaces so taken or conveyed in lieu of such taking and Landlord shall
decide to discontinue the use and operation of the Complex, or decide to
demolish, alter or rebuild the Complex, then, in any of such events Landlord
shall have the right to terminate this Lease by giving Tenant written notice
thereof within sixty (60) days of the date of receipt of said written advice, or
commencement of said action or proceeding, or taking conveyance, which
termination shall take place as of the first to occur of the last day of the
calendar month next following the month in which such notice is given or the
date on which title to the Premises shall vest in the condemnor.

        In the event of such a partial taking or conveyance of the Premises, if
the portion of the Premises taken or conveyed is so substantial that the Tenant
can no longer reasonably conduct its business, Tenant shall have the privilege
of terminating this Lease within sixty (60) days from the date of such taking or
conveyance, upon written notice to Landlord of its intention so to do, and upon
giving of such notice this Lease shall terminate on the last day of the calendar
month next following the month in which such notice is given, upon payment by
Tenant of the rent from the date of such taking or conveyance to the date of
termination.

        If a portion of the Premises be taken by condemnation or conveyance in
lieu thereof and neither Landlord nor Tenant shall terminate this Lease as
provided herein, this Lease shall continue in full force and effect as to the
part of the Premises not so taken or conveyed, and the



                                      18.
<PAGE>   56

rent herein shall be apportioned as of the date of such taking or conveyance so
that thereafter the rent to be paid by Tenant shall be in the ratio that the
area of the portion of the Premises not so taken or conveyed bears to the total
area of the Premises prior to such taking.

26. SALE OR CONVEYANCE BY LANDLORD.

        In the event of a sale or conveyance of the Complex or any interest
therein, by any owner of the reversion then constituting Landlord, the
transferor shall thereby be released from any further liability upon any of the
terms, covenants or conditions (express or implied) herein contained in favor of
Tenant, and in such event, insofar as such transfer is concerned. Tenant agrees
to look solely to the responsibility of the successor in interest of such
transferor in and to the Complex and this Lease for all obligations thereafter
arising. This Lease shall not be affected by any such sale or conveyance, and
Tenant agrees, upon recognition, to attorn to the successor in interest of such
transferor.

27. ATTORNMENT TO LENDER OR THIRD PARTY.

        In the event the interest of Landlord in the land and buildings in which
the leased Premises are located (whether such interest of Landlord is a fee
title interest or a leasehold interest is encumbered by deed of trust, and such
interest is acquired by the lender or any third party through judicial
foreclosure or by exercise of a power of sale at private trustee's foreclosure
sale. Tenant hereby agrees, upon recognition, to attorn to the purchaser at any
such foreclosure sale and to recognize such purchaser as the Landlord under this
Lease. In the event the lien of the deed of trust securing the loan from a
Lender to Landlord is prior and paramount to the Lease, this Lease shall
nonetheless continue in full force and effect for the remainder of the unexpired
term hereof, at the same rental herein reserved and upon all the other terms,
conditions and covenants herein contained.

28. HOLDING OVER.

        Any holding over by Tenant after expiration or other termination of the
term of this Lease with the written consent of Landlord delivered to Tenant
shall not constitute a renewal or extension of the Lease or give Tenant any
rights in or to the leased Premises except as expressly provided in this Lease.
Any holding over after the expiration or other termination of the term of this
Lease, with the consent of Landlord, shall be construed to be a tenancy from
month to month, on the same terms and conditions herein specified insofar as
applicable except that the monthly Basic Rent shall be increased to an amount
equal to one hundred fifty (150%) percent of the monthly Basic Rent required
during the last month of the Lease term.

29. CERTIFICATE OF ESTOPPEL.

        Tenant shall at any time upon not less than ten (10) days' prior written
notice to Landlord execute, acknowledge and deliver to Landlord a statement in
writing (i) certifying that this Lease is unmodified and in full force and
effect (or, if modified, stating the nature of such modification and certifying
that this Lease, as so modified, is in full force and effect) and the date to
which the rent and other charges are paid in advance, if any, and (ii)
acknowledging that there are not, to Tenant's knowledge, any uncured defaults on
the part of Landlord hereunder, or specifying such defaults, if any, are
claimed. Any such statement may be conclusively relied upon by any



                                      19.
<PAGE>   57

prospective purchaser or encumbrancer of the Premises. Tenant's failure to
deliver such statement within such time shall be conclusive upon Tenant that
this Lease is in full force and effect, without modification except as may be
represented by Landlord; that there are no uncured defaults in Landlord's
performance, and that not more than one month's rent has been paid in advance.

30. CONSTRUCTION CHANGES.

        It is understood that the description of the Premises and the location
of ductwork, plumbing and other facilities therein are subject to such minor
changes as Landlord or Landlord's architect determines to be desirable in the
course of construction of the Premises, and no such changes, or any changes in
plans for any other portions of the Complex shall affect this Lease or entitle
Tenant to any reduction of rent hereunder or result in any liability of Landlord
to Tenant. Landlord does not guarantee the accuracy of any drawings supplied to
Tenant and verification of the accuracy of such drawings rests with Tenant.

31. RIGHT OF LANDLORD TO PERFORM.

        All terms, covenants and conditions of this Lease to be performed or
observed by Tenant shall be performed or observed by Tenant at Tenant's sole
cost and expense and without any reduction of rent. If Tenant shall fail to pay
any sum of money, or other rent, required to be paid by it hereunder and such
failure shall continue for five (5) days after written notice thereof by
Landlord, or shall fail to perform any other term or covenant hereunder on its
part to be performed, and such failure shall continue for thirty (30) days after
written notice thereof by Landlord, Landlord, without waiving or releasing
Tenant from any obligation of Tenant hereunder, may, but shall not be obligated
to, make any such payment or perform any such other term or covenant on Tenant's
part to be performed. All sums so paid by Landlord and all necessary costs of
such performance by Landlord together with interest thereon at the rate of the
prime rate of interest per annum as quoted by the Bank of America from the date
of such payment or performance by Landlord, shall be paid (and Tenant covenants
to make such payment) to Landlord on demand by Landlord, and Landlord shall have
(in addition to any other right or remedy of Landlord) the same rights and
remedies in the event of nonpayment by Tenant as in the case of failure by
Tenant in the payment of rent hereunder.

32. ATTORNEYS' FEES.

        A. In the event that either Landlord or Tenant should bring suit for the
possession of the Premises, for the recovery of any sum due under this Lease, or
because of the breach of any provision of this Lease, or for any other relief
against the other party hereunder, then all costs and expenses, including
reasonable attorneys' fees, incurred by the prevailing party therein shall be
paid by the other party, which obligation on the part of the other party shall
be deemed to have accrued on the date of the commencement of such action and
shall be enforceable whether or not the action is prosecuted to judgment.

        B. Should Landlord be named as a defendant in any suit brought against
Tenant in connection with or arising out of Tenant's occupancy hereunder, Tenant
shall pay to Landlord its costs and expenses incurred in such suit, including a
reasonable attorney's fee.

33. WAIVER.

        The waiver by either party of the other party's failure to perform or
observe any term, covenant or condition herein contained to be performed or
observed by such waiving party shall not be deemed to be a waiver of such term,
covenant or condition or of any subsequent failure of the party failing to
perform or observe the same or any other such term, covenant or condition
therein contained, and no custom or practice which may develop between the
parties hereto during the term hereof shall be deemed a waiver of, or in any way
affect, the right of either party to insist upon performance and observance by
the other party in strict accordance with the terms hereof.

name and address shall have heretofore been furnished to Tenant in writing,
specifying wherein Landlord has failed to perform such obligations; provided,
however, that if the nature of Landlord's obligations is such that more than
thirty (30) days are required for performance, then Landlord shall not be in
default if Landlord commences performance within such thirty (30) day period and
thereafter diligently prosecutes the same to completion.

normally supplied by Landlord shall be 100 percent the responsibility of and be
paid for 100 percent by Tenant.

        It is further agreed that Tenant shall furnish Landlord with Tenant's
required specifications and a preliminary space plan showing the layout of the
improvements to be constructed in the Premises by November 15, 1999. At that
time, Landlord shall have the final interior plans drawn by Landlord's
architect. all of the plans and specifications shall be Exhibit B to this Lease.
If said preliminary plans and specifications for any items affecting the
interior improvements to be constructed in the building are not received by
Landlord for Landlord's approval (which approval shall not be unreasonably
withheld) by November 15, 1999, then it is agreed that, notwithstanding anything
to the contrary in this Lease, this Lease and Tenant's obligation to perform all
terms, covenants and conditions of this Lease shall commence February 15, 2000,
regardless of whether or not the building and interior improvements are
completed on February 15, 2000, and Landlord shall complete construction of the
interior improvements as soon as reasonably possible thereafter.

        Notwithstanding anything to the contrary, it is agreed that in the event
Tenant makes changes, additions, or modifications to the plans and
specifications to be constructed by Landlord as set forth herein, or
improvements are installed for Tenant in excess of those to be provided Tenant
by Landlord as set forth on Exhibit B, any increased cost(s) resulting from said
changes, additions, and/or modifications and/or improvements in excess of those
to be provided Tenant shall be contracted for with landlord and paid for one
hundred percent (100%) by Tenant.

        The interior shall be constructed in accordance with Exhibit B of the
Lease, it being agreed, however, that if the interior improvements constructed
by landlord relating thereto, do not conform exactly to the plans and
specifications as set forth in the Lease, and the general appearance, structural
integrity, and Tenant's uses and occupancy of the Premises and interior
improvements relating thereto are not materially or unreasonably affected by
such deviation, it is agreed that the commencement date of the Lease, and
Tenant's obligation to pay rental, shall not be affected, and Tenant hereby
agrees, in such event to accept the Premises and interior improvements as
constructed by Landlord.

        Tenant shall have thirty (30) days after the Commencement Date to
provide Landlord with a "punch list" pertaining to Landlord's work with respect
to Tenant's interior improvements. As soon as reasonably possible thereafter,
Landlord, or one of Landlord's



                                      27.

representatives (if so approved by landlord), and Tenant shall conduct a joint
walk-through of the Premises (if Landlord so requires), and inspect such Tenant
Improvements, using their best efforts to agree on the incomplete or defective
construction related to the Tenant Improvements installed by Landlord. After
such inspection has been completed, Landlord shall prepare, and both parties
shall sign, a list of all "punch list" items which the parties reasonably agree
are to be corrected by Landlord (but which shall exclude any damage defects
caused by Tenant, its employees, agents or parties Tenant has contracted with to
work on the Premises). Landlord shall have thirty (30) days thereafter (or
longer if necessary, provided Landlord is diligently pursuing the completion of
the same) to complete, at Landlord's expense, the repairs on the "punch list"
without the Commencement Date of the Lease and Tenant's obligation to pay Rental
thereunder being affected. This Paragraph shall be of no force and effect if
Tenant shall fail to give any such notice to Landlord within thirty (30) days
after the Commencement Date of this Lease.

45. CONSENT.

        Whenever the consent of one party to the other is required hereunder,
such consent shall not be unreasonably withheld.

46. CHOICE OF LAW: SEVERABILITY.

        This Lease shall in all respects be governed by and construed in
accordance with the laws of the State of California. If any provisions of this
Lease shall be invalid, unenforceable, or ineffective for any reason whatsoever,
all other provisions hereof shall be and remain in full force and effect.

47. AUTHORITY TO EXECUTE.

        The parties executing this Lease Agreement hereby warrant and represent
that they are properly authorized to execute this Lease Agreement and bind the
parties on behalf of whom they execute this Lease Agreement and to all of the
terms, covenants and conditions of this Lease Agreement as they relate to the
respective parties hereto.

48. ASSESSMENT CREDITS.

        The demised property herein may be subject to a special assessment
levied by the City of Redwood City as part of an Improvement District. As a part
of said special assessment proceedings (if any), additional bonds were or may be
sold and assessments were or may be levied to provide for construction
contingencies and reserve funds. Interest shall be earned on such funds created
for contingencies and on reserve funds which will be credited for the benefit of
said assessment district. to the extent surpluses are created in said district
through unused contingency funds, interest earnings or reserve funds, such
surpluses shall be deemed the property of Landlord. Notwithstanding that such
surpluses may be credited on assessments otherwise due against the Leased
Premises, Tenant shall pay to Landlord, as additional rent if, and at the time
of any such credit of surpluses, an amount equal to all such surpluses so
credited. For example: If (i) the property is subject to an annual assessment of
$1,000.00, and (ii) a surplus of $200.00 is credited towards the current year's
assessment which reduces the



                                      28.
<PAGE>   66

assessment amount shown on the property tax bill from $1,000.00 to $800.00,
Tenant shall, upon receipt of notice from Landlord, pay to Landlord said $200.00
credit as Additional Rent.

49. ASSIGNMENT AND SUBLETTING (CONTINUED).

        A. In addition to and notwithstanding anything to the contrary in
Paragraph 19 of this Lease and provided Tenant is not in default of this Lease,
Landlord hereby agrees to consent to: (1) Tenant's assigning or subletting said
Lease to: (i) any parent or subsidiary corporation, or corporation with which
Tenant merges or consolidates provided that the net worth of said parent or
subsidiary corporation, or said corporation has a net worth equal to or greater
than the net worth of Tenant (a) at the time of Lease execution or (b) at the
time of such assignment, merger, or consolidation (whichever is greater); or
(ii) any third party or entity to whom Tenant sells all or substantially all of
its assets; provided, that the net worth or the resulting or acquiring
corporation has a net worth after the merger, consolidation or acquisition equal
to or greater than the net worth of Tenant (a) at the time of Lease execution or
(b) at the time of such merger, consolidation or acquisition, whichever is
greater (collectively "Permitted Transfers"); (2) waive its right to terminate
the Lease due to a Permitted Transfer; and (3) waive any rights to Excess Rent
related to a Permitted Transfer. No such assignment or subletting will release
the Tenant from its liability and responsibility under this Lease to the extent
Tenant continues in existence following such transaction. Notwithstanding the
above, Tenant shall be required to (a) give Landlord written notice prior to
such assignment or subletting to any party as described in (i) and (ii) above,
(b) execute Landlord's consent document prepared by Landlord reflecting the
assignment or subletting and (c) pay Landlord's costs for processing said
Consent prior to the effective date of said assignment or sublease.

        B. Landlord hereby acknowledges that, during the first three years of
the Lease Term, Tenant intends to sublease all or a portion of the Leased
Premises. Provided Tenant is not in default of this Lease and the prospective
subtenant(s) use complies with the requirements of the "use" as stated in
Paragraph 1, Landlord agrees that it will not exercise its right, as provided
for in Paragraph 19, to terminate the Lease as a result of Tenant's initial
request(s) to sublease all or a portion of the Premises for a sublease term(s)
not to extend beyond February 14, 2003. In each such event, Landlord agrees to
issue Landlord's standard consent to said sublease, subject to (a) Tenant
submitting to Landlord a copy of said sublease(s) (prior to said sublease
commencing), (b) Landlord, Tenant and Subtenant(s) thereafter executing
Landlord's standard Consent to Sublease agreement and (c) Landlord receiving
payment from Tenant of Landlord's costs for processing said Sublease Consent(s)
prior to said sublease commencing.

        C. Notwithstanding the foregoing, Landlord and Tenant agree that it
shall not be unreasonable for Landlord to refuse to consent to a proposed
assignment, sublease or other transfer ("Proposed Transfer") if the Premises or
any other portion of the Property would become subject to additional or
different Government Requirements as a direct or indirect consequence of the
Proposed Transfer and/or the Proposed Transferee's use and occupancy of the
Premises and the Property. However, Landlord may, in its sole discretion,
consent to such a Proposed Transfer where Landlord is indemnified by Tenant and
(i) Subtenant or (ii) Assignee, in form and substance satisfactory to Landlord's
counsel, by Tenant and/or the Proposed Transferee from and against any and all
costs, expenses, obligations and liability arising out of the Proposed Transfer
and/or the Proposed Transferee's use and occupancy of the Premises and the
Property.

<PAGE>   67

        D. Any and all sublease agreement(s) between Tenant and any and all
subtenant(s) (which agreements must be consented to by Landlord, pursuant to the
requirements of this Lease) shall contain the following language:

                "If Landlord and Tenant jointly and voluntarily elect, for any
        reason whatsoever, to terminate the Master Lease prior to the scheduled
        Master Lease termination date, then this Sublease (if then still in
        effect) shall terminate concurrently with the termination of the Master
        Lease. Subtenant expressly acknowledges and agrees that (1) the
        voluntary termination of the Master Lease by Landlord and Tenant and the
        resulting termination of this Sublease shall not give Subtenant any
        right or power to make any legal or equitable claim against Landlord,
        including without limitation any claim for interference with contract or
        interference with prospective economic advantage, and (2) Subtenant
        hereby waives any and all rights it may have under law or at equity
        against Landlord to challenge such an early termination of the Sublease,
        and unconditionally releases and relieves Landlord, and its officers,
        directors, employees and agents, from any and all claims, demand, and/or
        causes of action whatsoever (collectively, "Claims"), whether such
        matters are known or unknown, latent or apparent, suspected or
        unsuspected, foreseeable or unforeseeable, which Subtenant may have
        arising out of or in connection with any such early termination of this
        Sublease. Subtenant knowingly and intentionally waives any and all
        protection which is or may be given by Section 1542 of the California
        Civil Code which provides as follows: "A general release does not extend
        to claims which the creditor does not know or suspect to exist in his
        favor at the time of executing the release, which if known by him must
        have materially affected his settlement with debtor.

                The term of this Sublease is therefore subject to early
        termination. Subtenant's initials here below evidence (a) Subtenant's
        consideration of and agreement to this early termination provision, (b)
        Subtenant's acknowledgment that, in determining the net benefits to be
        derived by Subtenant under the terms of this Sublease, Subtenant has
        anticipated the potential for early termination, and (c) Subtenant's
        agreement to the general waiver and release of Claims above.

50. BANKRUPTCY AND DEFAULT.

        Paragraph 22 is modified to provide that with respect to non-monetary
defaults not involving Tenant's failure to pay Basic Rent or Additional Rent,
Tenant shall not be in default of any non-monetary obligation if (i) more than
thirty (30) days is required to cure such non-monetary default, and (ii) Tenant
commences cure of such default as soon as reasonably practicable after receiving
written notice of such default from Landlord and thereafter continuously and
with due diligence prosecutes such cure to completion.

<PAGE>   68

51. ABANDONMENT.

        Paragraph 23 is modified to provide that Tenant shall not be in default
under the Lease if it leaves all or any part of Premises vacant so long as (i)
Tenant is performing all of its other obligations under the Lease including the
obligation to pay Basic Rent and Additional Rent (ii) Tenant provides on-site
security during normal business hours for those parts of the Premises left
vacant, (iii) such vacancy does not materially and adversely affect the validity
or coverage of any policy of insurance carried by Landlord with respect to the
Premises, and (iv) the utilities and heating and ventilation system are operated
and maintained to the extent necessary to prevent damage to the Premises or its
systems.

of the environment, ecology, natural resources, or public health and safety.

        B. Tenant shall obtain Landlord's written consent, which may be withheld
in Landlord's discretion, prior to the occurrence of any Tenant's Hazardous
Materials Activities (defined below); provided, however, that Landlord's consent

Landlord in addition to any other rights it may have under this Lease or under
environmental Laws or other laws, may enter upon the Property and conduct
inspection, sampling and analysis, including but not limited to obtaining and
analyzing samples of soil and groundwater, for the purpose of determining the
nature and extent of such contamination. Tenant shall promptly reimburse
Landlord for the costs of such an investigation, including but not limited to
reasonable attorneys' fees Landlord incurs with respect to such investigation,

Environmental Laws. Tenant shall not perform any sampling, testing, or drilling
to identify the presence of any Hazardous materials at the Property, without
landlord's prior written consent which may be withheld in Landlord's discretion.

shall be refunded to Tenant upon Landlord's receipt of an acceptable irrevocable
letter of credit. If Tenant defaults with respect to any provisions of this
Lease, including but not limited to provisions relating to the payment of Rent,
landlord may (but shall not be required to) draw down on the irrevocable letter
of credit for payment of any sum which Landlord may spend or become obligated to
spend by reason of Tenant's default, or to compensate Landlord for any loss or
damage which Landlord may suffer by reason of Tenant's default. Landlord and
Tenant acknowledge that such irrevocable letter of credit will be treated as if
it were a cash Security Deposit, and such irrevocable letter of credit may be
drawn down upon by Landlord upon demand and presentation of evidence of the
identity of landlord to the issuing bank, in the event that Tenant defaults with
respect to any provision of this Lease and such default is not cured within any
applicable cure period. Landlord acknowledges that it is not entitled to draw
down such irrevocable letter of credit unless Landlord would have been entitled
to draw upon a cash Security Deposit pursuant to the terms of Paragraph 4G of
the Lease. Concurrently with the delivery of the required information to the
issuing bank, Landlord shall deliver to Tenant written evidence of the default
upon which the draw down was based, together with evidence that Landlord has
provided to Tenant the written notice of such default which was required under
the applicable provision of the Lease, and evidence of the failure of Tenant to
cure such default within the applicable grace period following receipt of such
notice of default. If any portion of the irrevocable letter of credit is used or
applied pursuant hereto, Tenant shall, within ten (10) days after receipt of a
written demand therefor from Landlord, restore and replace the value of such
security by either (i) depositing cash with Landlord in the amount equal to the
sum drawn down under the irrevocable letter of credit, or (ii) increasing the
irrevocable letter of credit to its value immediately prior to such application.
Tenant's failure to replace the value of the security as provided in the
preceding sentence shall be a material breach of its obligation under this
lease.

57. ASSIGNMENT OF WARRANTIES.

        During the Term of the Lease, Landlord hereby assigns to Tenant all of
Landlord's Contractors' warranties and shall cooperate with Tenant in enforcing
any of such warranties



                                      36.
<PAGE>   74

except that Landlord shall not be required to pay any legal fees or incur any
expenses in this regard.

58. BROKERS.

        Landlord and Tenant each represent to the other that they have dealt
with no real estate brokers, agents, or finders in connection with this
transaction, except as follows: Cornish & Carey Oncor International ("C&C"),
whose commission shall be paid by Landlord in accordance with landlord's
standard commission schedule which commission for this Lease is a total of
$100,000.00. Each party agrees to defend, protect, indemnify and hold the other
party harmless from and against all claims for brokerage commissions, finder's
fees, and other compensation made by any broker, agent, or finder as consequence
of the indemnifying party's actions or dealings with such broker, agent or
finder. The parties hereto acknowledge that landlord will not pay an additional
brokerage fee to C&C or any broker in the event the term of this Lease is
extended for any reason whatsoever.

                                 AMENDMENT NO. 1

                       DIAL UP NETWORK SERVICES AGREEMENT

        This amendment (the "Amendment") to the Dial Up Network Services
Agreement between BBN Planet Corporation and i-Pass Alliance Inc. dated October
15, 1996 (the "Agreement") revises certain terms and conditions in the
Agreement.

The parties agree to amend the Agreement as follows:.

1. Delete Section 1.6 "Term" and substitute the following:

        1.6 "Term" shall mean the period beginning on the Commencement Date and
        extending until December 31, 1997.

2. Delete Section 5.2 Customer Committed Hours and replace with the following:

        5.2     Customer Committed Hours. Customer understands and agrees that
                it is obligated to pay for the minimum number of hours of
                Network Access Service specified as Customer Committed Hours as
                set forth in Exhibit C. Section A.2. Based on the Customer
                Committed Hours amount, BBN Planet will invoice Customer for BBN
                Basic Services at the hourly rate set forth in Exhibit C,
                Section A.1. Customer acknowledges and understands that it is
                obligated to pay the full amount due for the Customer Committed
                Hours notwithstanding the fact that cumulative actual network
                access service connect hours during the Term may be less than
                the Customer Committed Hours amount. In such event, Customer
                agrees to pay an amount which is the difference between (a) the
                total amount due for the Customer Committed Hours at the Local
                Access Service rate less (c) the amount due for actual network
                Access Service connect hours at the Local Access Service rate.
                Such amount is due and payable within thirty days of the last
                day of the Term.

3. Delete Section 8.1 Term and replace with the following:

        8.1 Term. The Term of this Agreement shall begin on the Commencement
        Date and extend until December 31, 1997.

4. Delete Exhibit C. Prices and substitute the revised Exhibit C as set forth in
Attachment No. 1 to this Amendment.

5. Change all references to "BBN Planet Corporation" in the Agreement to "BBN
Planet, a division of BBN Corporation.

6. Other Matters

        6.1 BBN Planet Engineering Activities. BBN Planet agrees to carry out
the following engineering activities for the benefit of Customer:



                                      15.
<PAGE>   16

                6.1.1 BBN Planet agrees to implement additional "redundancy" of
                DiaLinx user authentication by adding to BBN Planet's RADIUS
                authentication procedure the capability to utilize a second or
                backup i-Pass RADIUS Server if Customer's primary RADIUS Server
                is unavailable. This capability will be delivered to i-Pass by
                4/15/97. Cost: [*]. Until BBN Planet delivers this
                "redundancy" capability, BBN Planet and i-Pass will implement a
                mutually agreeable interim, low cost solution by 1/31/97.

                6.1.2 BBN Planet will identify at the time of user authorization
                any user accessing the BBN Planet dial network via the 800
                number. BBN Planet will provide a new attribute in the
                authentication request packet that will flag the call as an
                "800" access call. It will the responsibility of the i-Pass
                end-user RADIUS server to use this information in conjunction
                with the account name and password to authorize or deny access.
                This capability will be delivered to i-Pass by 4/30/97. Cost:
                [*]. Until BBN Planet delivers this "800 Identification"
                capability, BBN Planet and i-Pass will implement a mutually
                agreeable interim, low cost solution by 1/31/97.

                6.1.3 i-Pass desires that BBN Planet provide "real-time"
                disconnect data for each user. Ascend Communications has advised
                BBN Planet that it plans to include an enhancement to track and
                pass real-time disconnect data in the next version of the
                Ascend software, Version 5.0. BBN Planet will provide the per
                user session information in real-time via RADIUS accounting
                packets to i-Pass, i-Pass is responsible to modify its RADIUS
                servers to support a new accounting server attribute in each
                user profile. Expected availability of Ascend software Version
                5.0 on our network is April-May `97. BBN Planet will provide the
                information on the specification to support this feature to
                i-Pass by February 28, 1997. BBN Planet shall have no obligation
                to provide "real time" disconnect data in the event that the
                next version of Ascend does not include the capability to track
                and pass real-time disconnect data as noted above.

                6.1.4 BBN Planet and i-Pass agree to limit the number of realms
                assigned to i-Pass and to establish a naming convention which
                uniquely identifies BBN Planet's customers and i-Pass'
                customers. On a reasonable efforts basis, BBN Planet and i- Pass
                will implement a mutually agreeable approach for accomplishing
                these objectives by 4/1/97. Until this approach is implemented,
                BBN Planet will continue to support i-Pass' realm requirements
                and its current naming convention.

                6.1.5 Consideration. In consideration for BBN Planet's agreement
                to undertake the engineering activities as described in
                Paragraphs 6.1.1 and 6.1.2 above, Customer agrees to make a
                nonrefundable prepayment of [*] (for 6000 hours of Local
                Access Service) for the aforementioned engineering activities as
                described above (i.e, a total of [*]) which amounts are
                due and payable within fifteen days of the completion of each

                activity. These amounts will be credited against amounts due and
                payable under Section 5. for BBN Planet Basic Services.

        6.2 Dialinx Pricing Assurance. If BBN Planet agrees to provide BBN
        Planet Basic Services to one or more of the following competitors of
        Customer ("Competitors") at prices (based on substantially similar
        Customer Committed Hours, terms and conditions) which are less than
        those granted to Customer under this Agreement, BBN Planet will so
        advise Customer. BBN Planet may elect, but shall have no obligation, to
        offer revised prices to Customer which are comparable to those offered
        to a Competitor. In the event that BBN Planet elects not to offer
        revised prices to Customer, Customer shall have the right to terminate
        this Agreement at its convenience. If Customer elects to so terminate,
        Customer's obligation under Section 5.2 Customer Committed Hours (as set
        forth in the Agreement as amended) shall expire.

        Competitors of Customer are as follows:

        [List no more than two companies]: AimQuest, EUnet AimQuest, EUnet

During the Term Customer shall have the right to add up to four additional
companies to the above list upon delivery of written notice to BBN Planet.

        6.3 BBN Planet Marketing Support

                6.3.1 To facilitate Customer's sales efforts, BBN Planet will
                carry out the marketing support activities as described in
                Attachment No. 2.

                6.3.2 In the event that BBN Planet fails to complete any of the
                Marketing Support activities as described in Attachment No. 2,
                BBN Planet will reduce the Customer Committed Hours amount as
                set forth in Exhibit C (as revised) by the amount of hours set
                listed in Attachment No. 2.

All other terms and conditions in the Agreement remain unchanged.

                     EXHIBIT C FOR DIALINX SERVICE FOR IPASS
- --------------------------------------------------------------------------------

This Exhibit C shall supercede the Exhibit C in the Dial-Up Network Services
Agreement dated December 21, 1998 ("Agreement") and any amendment thereto,
provided, however, that all fees for services delivered prior to the execution
of this revised Exhibit C are still due.

1.      Pricing Summary: This section highlights the general elements of pricing
        and commitments:

1.1     Network Access. You will be billed for each end user that may access the
        GTE Internetworking DiaLinx network ("North American Network") in
        accordance with the pricing options set forth herein. You will be
        charged for Network Access, which, for each calendar month, shall be the
        greater of either (a) Access charges due in accordance with Section 5
        "Rates and Charges" or (b) Monthly Customer Commitment as set forth in
        Section 2 "Minimum Monthly Commitment".

        1.2     Monthly Customer Commitment: In return for volume discounts
                (inherent in the prices stated below) you have agreed to use a
                minimum dollar volume of network access in each month of the
                agreement ("Monthly Customer Commitment"). In the event that
                your actual network access charges do not meet the Monthly
                Customer Commitment, you will be billed for the applicable
                Monthly Customer Commitment (the difference between you actual
                network access usage and the Monthly Customer Commitment is the
                "Commitment Payment")

        1.3     Term Commitment: The aggregate of the Monthly Customer
                Commitment is [*] ("Term Commitment"). In the event your
                actual network access charges exceeds the Term Commitment all
                subsequent Monthly Customer Commitment obligations shall be
                suspended.

        1.4     If, at the end of each twelve (12) month period, your actual
                network access charges exceeds [*] ("Annual Commitment") and you
                have paid a Commitment Payment, you will be credited either (a)
                the amount Customer has exceeded the Annual Commitment or (b)
                the applicable Commitment Payment, whichever is less.

                For example:
                If Customer's actual network access charges reached [*] in month
                12 and during that same period Customer made one Commitment
                Payment of [*], then Customer shall be issued a credit equal
                to [*]. (Example One)

                If Customer's actual network access charges reached [*] in month
                12 and Customer had never made a Commitment Payment, then
                Customer shall not be issued a credit in this example. (Example
                Two)

2.      Minimum Customer Commitment. During the Service Period, in return for
        discounts inherent in the pricing outlined therein, you have agreed to
        use a minimum dollar volume of network access in the amount of
        two-hundred-thousand-dollars ([*] per month, after discounts, of
        the agreement ("Minimum Customer Commitment"). In the event that Network
        access charges do not meet the Minimum Customer Commitment you will be
        billed for the difference between the amount actually charged within the
        given month and the Minimum Customer Commitment.

3.      Commencement Date: The terms and conditions of this Exhibit C shall be
        applied to charges assessed in the month of December (1999) if the
        Agreement is executed on or before December 17, 1999. In the event this
        Agreement is executed after December 15, 1999, the terms and conditions
        of this Exhibit C shall be applied to charges assessed in the month of
        January (2000).

4.      Service Period. The Service Period shall be thirty-six (36) full
        calendar months.

5.      Rates and Charges: All rates and charges for the services defined in
        this Section 5. All network connect time is rounded up to the next

                        this Agreement for a phase-out period of ninety (90)
                        days, and GTE shall cooperate and assist Customer in

                  8.6.2 We reserve the right, but assume no obligation, to
                        terminate performance immediately if you are more than
                        30 days overdue in payments. Additionally, we reserve
                        the right to terminate performance if you have violated
                        (a) any laws concerning the transmission of technical
                        data and/or other regulated material or 9b) our
                        acceptable use of policy which is attached hereto as
                        Exhibit D ("Acceptable Use Policy"). Prior to
                        termination of the Service (or any portion thereof) for
                        said violation, we shall provide you with written
                        notification and a ten (10) day cure period from your
                        receipt of such notification. If the violation has not
                        been rectified by the end of the third day of the ten
                        (10) day cure period, we reserve the right to suspend
                        service for the remainder of the ten (10) day cure
                        period. If, the violation has not been rectified after
                        the ten (10) day cure period, we reserve the right to
                        terminate performance. Notwithstanding the foregoing, if
                        the violation is of a nature that disrupts the network
                        in a technical and/or operational manner ("Operational
                        Violation"), we reserve the right to immediately suspend
                        or terminate performance; provided however that
                        performance due to an Operational Violation will be
                        suspended for no more than 10 days in any three (3)
                        month period. GTE may modify the Acceptable-Use Policy
                        only to accommodate (i) the standard business practices
                        and social policies of the internet community; (ii)
                        compliance with administrative directives, legal
                        precedent and/or applicable legislation; or (iii) the
                        reasonable business and economic concerns of GTE
                        Internetworking. If, at any time, we change the
                        Acceptable Use Policy in a material manner which we
                        attempt to

shall be forwarded to such reseller or downstream service provider for
resolution. If at time GTE Internetworking determines that such reseller or
downstream service provider is not taking appropriate action in accordance with

downstream service provider to review their policies and enforcement procedures.

o     Infringes any copyright, trademark, trade secret, or other intellectual
      property right.

Internetworking will notify or cooperate with applicable law enforcement
authorities for potential civil or criminal investigation or prosecution.

B.      ABUSE

The following general actions are considered "abuse" and are strictly
prohibited:

Any conduct which violates the accepted norms and expectations of the Internet
community at large (whether or not detailed in this Acceptable Use Policy). GTE
Internetworking reserves the

                                       4
<PAGE>   40
right, in its sole discretion, to make a determination whether any particular
conduct violates such norms and expectations.

Resale of GTE Internetworking's services or products, unless expressly
authorized in a separate written agreement with GTE Internetworking.

o       Any conduct that restricts or inhibits any other user, whether a
        customer of GTE Internetworking or a user of any other system or
        network, from using or enjoying any of GTE Internetworking's services or
        products, as determined by GTE Internetworking in its sole discretion.

o       Harassment, whether through language, frequency, or size of messages.

o       Creating, forwarding, posting, or distribution of chain messages of any
        type (also known as "pyramid" or "Ponzi" schemes).

o       Forging of message headers or a sender's identity, or taking any similar
        action with the intent of bypassing restrictions or limits on access to
        a specific service or site (such as a moderated newsgroup or a site
        utilizing filters). This prohibition does not restrict the legitimate
        use of aliases or anonymous re-mailers.

o       Falsifying identity or contact information (whether given to GTE
        Internetworking, to the InterNIC, or put in a message header) to
        circumvent this Acceptable Use Policy. This prohibition does not
        restrict the legitimate use of aliases or anonymous re-mailers.

o       Furnishing false or incorrect data to GTE Internetworking on written or
        online applications, contracts, or other materials or formation provided
        to GTE Internetworking, including fraudulent use of credit card numbers
        or "bill to" telephone numbers.

o       Attempting to circumvent or alter the processes or procedures to measure
        time, bandwidth utilization, or other methods to document use of GTE
        Internetworking's products and services.

C.      SECURITY

Violations of system or network security are prohibited, and may result in
criminal and civil liability. GTE Internetworking will investigate potential
security violations, and may notify applicable law enforcement agencies if
violations are suspected.

It is strictly prohibited to attempt to circumvent the authentication procedures
or security of any host, network, network component, or account (i.e.,
"cracking") to access data, accounts, or servers which the user is not expressly
permitted or authorized to access. This prohibition applies whether or not the
attempted intrusion is successful, and includes unauthorized probes or scans
performed with the intent to gather information on possible security weaknesses
or exploitable configurations.

Users of the GTE Internetworking Network are responsible for educating
themselves and configuring their systems with at least basic security. Should
systems at a user's site be violated,


                                       5
<PAGE>   41
the user is responsible for reporting the violation and then fixing the
exploited system. For instance, should a site be abused to distribute unlicensed
software due to a poorly configured FTP (File Transfer Protocol) Server, the
user is responsible for re-configuring the system to stop the abuse.

Users are prohibited from interfering or attempting to interfere with service to
any other user, host, or network on the Internet ("denial of service attacks").
Examples of such prohibited activity include without limitation (a) sending
massive quantities of data (i.e., "flooding" with ICMP, SMTP, or any other type
of traffic that exceeds accepted norms of size and/or frequency) with the intent
of filling circuits, overloading systems, and/or crashing hosts, (b) attempting
to attack or disable any user, host, or site, or (c) using, distributing, or
propagating any type of program, script, or command designed to interfere with
the use, functionality, or connectivity of any Internet user, host, system, or
site (for example, by propagating messages, via e-mail, ______ posting, or
otherwise, that contain computer worms, viruses, control characters or Trojan
horses).

Users are prohibited from intentionally or negligently injecting false data into
the Internet, for instance in the form of bad routing information (including but
not limited to the announcing of networks owned by someone else or reserved by
the Internet Assigned Numbers Authority) or incorrect DNS information.

D.      E-MAIL

mail ("e-mail") over the Internet. Without limitation of the foregoing, it is
strictly prohibited to engage in any of the following activities:

o     Sending unsolicited bulk e-mail ("UBE", or "spamming"). This includes, but
      is not limited to, the distribution of UBE for commercial, informational,
      advertising, political, or religious purposes.

o     Setting up "mailback" or "drop box" addresses in order to receive
      responses from UBE, either directly by the user or by a third party on
      behalf of the user.

o     Using a mail transport agent (MTA) outside of a user's own site to relay
      mail (unless a user has received express permission to do so). Even if
      permission has been received, users are prohibited from forging their
      identities to make it appear as though the e-mail sourced from the relay.

o     Sending UBE, or posting news, to advertise or promote resources whose
      connectivity depends in any way on the GTE Internetworking Network,
      regardless of whether such UBE or news posting is made using the GTE
      Internetworking Network. For example, using another ISP's services to send
      UBE which advertises a web page hosted by or via the GTE Internetworking
      Network is prohibited.

o     Hiring or using any third party service for the purpose of distributing
      UBE or excessively "multi-posting" or "cross-posting" any ______ posting
      in the name of a user. Users will be

                                       6
<PAGE>   42

      held responsible for the actions of any third party agent that acts on
      behalf of or for the benefit of the user, and such users shall be held
      directly accountable for any violations of this Acceptable User Policy by
      such third party agent.

o     Bulk e-mail may be sent only to recipients who have expressly requested
      receipt of such e-mail. Users that send solicited bulk e-mail are required
      to maintain records of all bulk e-mail subscription requests, and to
      provide GTE Internetworking with such records upon request of GTE
      Internetworking, to enable GTE Internetworking to investigate complaints
      from third parties. The sender of any solicited bulk e-mail shall, upon
      the request of a recipient, immediately remove such recipient from all
      applicable mailing lists and refrain from further transmissions of e-mail
      to such recipient.

o     Use of any auto-responder messages, mailing lists, or any other programs
      or scripts run by a user to handle or re-distribute e-mail is the sole
      responsibility of the user, and shall be operated in a reasonable manner.
      This responsibility includes, but is not limited to, maintaining
      up-to-date mailing lists to minimize mail bouncing and to facilitate the
      processing of removal requests, configuring auto-responders so that they
      do not create mail loops, and the prompt handling of any complaints
      regarding UBE re-distributed through a mailing list onsite.

E.      UNSENET (ALSO KNOWN AS NETNEWS OR NEWSGROUPS)

GTE Internetworking recommends that users not post to any newsgroup until they
have familiarized themselves with the subjects, established guidelines, and
restrictions of such newsgroup. All Usenet guidelines and restrictions are
incorporated herein by reference, and users of the GTE Internetworking Network
agree to adhere to such guidelines unconditionally.

Without limitation of the foregoing, it is strictly prohibited to engage in any
of the following activities:

o     Making any posting for commercial purposes (including without limitation
      the pointing to specific URLs for commercial purposes), except where such
      postings are expressly permitted under the charter and/or Frequently Asked
      Questions (FAQ) of an applicable newsgroup.

o     Posting binary files to newsgroups whose charter or name does not include
      allowances for such files.

o     Posting via GTE Internetworking's newsfeed any solicitation for mailback
      to an e-mail address (including addresses of non-GTE Internetworking
      users) networks with the intention of bypassing this Acceptable Use
      Policy.

o     Canceling newsgroup posting other than their own, or using auto-responders
      or cancel-bots (or similar automated or manual routines) which generate
      excessive network traffic or disrupt Usenet newsgroup/e-mail use by others
      (except in cases of official newsgroup moderators performing their
      duties).


                                      7
<PAGE>   43

o     Engaging in "Excessive Cross-Posting" (ECP) or "Excessive Multi-Posting"
      (EMP) or "Usenet spam" (no matter what the content might be) as defined by
      the Internet community and expressed in the news.admin.net-abuse."
      Newsgroups and FAQs.

o     Disrupting newsgroups with materials, postings, or activities that are (as
      determined by GTE Internetworking in its sole discretion) frivolous,
      unlawful, obscene, threatening, abusive, libelous, hateful, excessive, or
      repetitious, unless such materials or activities are expressly allowed or
      encouraged under the newsgroup's name, FAQ, or charter.

o     Using filtering messages (e.g., NoCoM) in an intrusive manner, or at other
      than the user's server level. Generally, filtering messages are considered
      normal Usenet traffic and are treated as such by GTE Internetworking.
      Complaints regarding filter use or abuse should be directed either to the
      source generating them or the sites utilizing them.

o     Performing any authorized creation, cancellation, or removal of
      newsgroups.

The legitimacy of a given post or cancellation is determined by the official
newsgroup or mailing-list moderator. Therefore, GTE Internetworking defers to
their judgment on these issues. If no such official entity exists, it is at GTE
Internetworking's discretion to determine whether any post or cancellation is
complaint with this Acceptable Use Policy and Internet community standards for
that newsgroup.

F.      WORLD WIDE WEB

GTE Internetworking strictly prohibits users from engaging in any of the
following web-related activities:

o     The exploitation or attempted exploitation of any scripts presented on web
      pages (e.g., forms for answering questions or for entering data).

o     Excessive use of bandwidth by utilizing programs, scripts, or commands to
      abuse a web site (for example, by connecting for an excessive amount of
      time, repeatedly engaging site-local scripts, or related behavior).

o     "Walking" a database for the purpose of collecting data contained therein
      (whether or not this behavior requires that the reader of the page must
      knowingly ignore files such as "robot.txt" which is designed to guide
      cataloguing robots/programs).

o     Operating a robot on a site's page after the site has asked that the
      behavior cease.

o     Configuring a web page to act maliciously against users that visit that
      web page.

CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY BRACKETS,
HAS BEEN OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
COMMISSION PURSUANT TO RULE 406 OF THE SECURITIES ACT OF 1933, AS AMENDED.

                                                                   EXHIBIT 10.11

                   VIRTUAL INTERNET PROVIDER (VIP) AGREEMENT

This Agreement is made in the city of Fairfax, Virginia, this 9th day of January
1997, between UUNET Technologies, Inc., whose address is 3060 Williams Drive,
Fairfax, Virginia 22031 (UUNET), and i-Pass Alliance Inc., (Reseller), whose
address is 650 Castro Street, Suite 280 Mountain View, CA 94041.

The parties hereto agree and bind themselves as follows:

1. SERVICE. UUNET will sell, and Reseller will purchase, telecommunications
services for the interconnection of Reseller's end users with the Internet.
Reseller is responsible for all end-user customer support, billing, and
collections. UUNET's relationship under this Agreement is solely with Reseller
and not with any of reseller's end users. UUNET agrees that its
telecommunications services provided to Reseller will be of a quality usual and
customary in the industry for similarly situated companies. Although it is
understood that UUNET cannot guarantee continuous service, UUNET agrees to
provide prompt reparation of any disruption in services to the extent reasonably
possible consistent with its obligations to other customers. To this end, UUNET
agrees to provide Reseller with a toll-free number to report problems relating
to network integrity. This number is to be used only by Reseller and will not be
released to Reseller's customers.

2. PRICING. For PPP dial-up traffic (analog dial, 28.8Kbps and ISDN) and VIP
radius server interoperability, the prices contained in Schedule A apply. For
all other services, UUNET's list prices apply unless other prices have been
specifically established.

3. TERMS AND CONDITION. Reseller agrees to comply with the Network Services
Terms and Conditions contained in Schedule B. It further agrees to require its
end users to comply with terms and conditions in substance identical to those in
Sections One and Two of Schedule B. Reseller shall defend, indemnify, and hold
harmless UUNET against any claims resulting from Reseller's use of UUNET's
services, or that of its customers throughout its chain of distribution.

4. PUBLICITY. The prices and terms of this Agreement shall be held confidential
by both parties. Neither party shall publicize the existence of this agreement
without the consent of the other, and in the event of such agreement, all press
release materials shall be reviewed and approved by the other party.

5. TECHNICAL AGREEMENT. Reseller agrees to comply with the Technical Agreement
for Network Interoperability, attached as Schedule C.

6. TERM. The term of this Agreement is one year from the date of contract
signature, which term shall be automatically renewed for additional one year
terms, provided that neither party has delivered to the other party a written
notice of intent not to renew for the forthcoming term. Such notice of intent
shall be given not less than sixty (60) days in advance of the end of the
current term.

7. TERMINATION. Either party may terminate this Agreement for cause without
penalty in the event that the other party hereto breaches any material term of
this Agreement. Prior to such termination, the party intending to terminate
shall first give the other party written notice of its



                                       1.
<PAGE>   2

intent to terminate which shall clearly describe problem(s) constituting cause.
The other party will have thirty (30) days from the date of receipt of such
notice to correct the problem. If the problem is not corrected within such
period, the party intending to terminate may terminate this Agreement on such
30th day. However, if Reseller shall violate the acceptable use policy in
Section 2 of Schedule B, or permit such violation, and does not immediately act
to remedy such violation when it becomes aware of it, UUNET may terminate this
Agreement without penalty with ten (10) days written notice. If any amounts due
and owing by Reseller remain unpaid sixty (60) days after date of invoice, then
UUNET may terminate this Agreement immediately upon written notice without
penalty.

8. TESTING. The full effectiveness of this contract will be contingent upon the
completion of technical testing to the mutual and reasonable satisfaction of
both parties during the period of thirty (30) days following execution of this
Agreement. If either party shall reasonably declare the testing results to be
unsatisfactory at the conclusion of this thirty (30) day period, then the
parties shall have another ten (10) days to correct the problem. If such
correction is not completed to the mutual and reasonable satisfaction of the
parties then this Agreement will terminate with not further liability to either
party. If no such declaration is made, acceptance of technical testing shall be
presumed, and the contract shall remain in effect. Monthly minimums will begin
to accrue from the date of the satisfactory completion of technical testing. If
testing is completed during the course of a month, the first month's minimum
commitment will be prorated to reflect the shortened month.

9. LIMITATION OF LIABILITY. NOTWITHSTANDING ANYTHING ELSE TO THE CONTRARY
STATED OR IMPLIED HEREIN, NEITHER PARTY SHALL HAVE ANY LIABILITY WHATSOEVER FOR
ANY INCIDENTAL CONSEQUENTIAL OR SPECIAL DAMAGES SUFFERED BY THE OTHER OR BY ANY
ASSIGNEE OR OTHER TRANSFEREE OF THE OTHER, EVEN IF INFORMED IN ADVANCE OF THE
POSSIBILITY OF SUCH DAMAGES, EXCEPT IN CONNECTION WITH THE INDEMNIFICATION
PROVISIONS OF SECTION 3 OF THIS AGREEMENT AND SECTION 2 OF SCHEDULE B.

10. GOVERNING LAW. This Agreement and the rights of the parties hereunder shall
be governed by and interpreted in accordance with the laws of the Commonwealth
of Virginia, USA, and the parties agree that any appropriate state or district
court located in Fairfax County, VA, shall have exclusive jurisdiction over any
case of controversy arising hereunder, and shall be the proper forum in which to
adjudicate such case or controversy.

11. ENTIRE AGREEMENT. The parties hereto acknowledge that they have read this
entire Agreement and that this Agreement and the exhibits attached hereto
constitute the entire understanding and contract between the parties and
supersedes any and all prior or contemporaneous oral or written communications
with respect to the subject matter hereof. This Agreement shall not be modified,
amended or in any way altered except by an instrument in writing signed by the
parties.

12. RELATIONSHIP OF PARTIES. No agency, partnership, joint venture or employment
is created as a result of this Agreement. Neither party is authorized to bind
the other in any respect whatsoever.

13. BINDING EFFECT. Except as herein otherwise specifically provided, this
Agreement shall be binding upon and inure to the benefit of the parties and
their legal representatives, heirs, administrators, executors, successors and
assigns.

14. FORECASTS. Reseller shall provide UUNET with initial and periodically
revised forecasts of its expected usage, and recognizes UUNET's reliance upon
the reasonable accuracy of these forecasts. Specifically, during the first week
of each calendar month. Reseller shall provide UUNET with its best forecast of
users and hours for each remaining month of the terms of the Agreement. Reseller
shall also provide UUNET with any information as to marketing programs which
will be helpful in determining expected future loads, particularly any
information relevant to expected loads in particular geographical
locations/POPs.

15. CONFIDENTIALITY. The parties agree that all disclosures of confidential
and/or proprietary information during the term of this Agreement shall
constitute confidential information of the disclosing party. Each party shall
use its best efforts to ensure the confidentiality of such information supplied
by the disclosing party, or which may be acquired by either in connection with
or as a result of the provision of the services under this Agreement. Both
parties warrants that they shall not disclose, use, modify, copy, reproduce, or
otherwise divulge such confidential information. Both parties further agree to
prevent its employees and representatives from disclosing, using, modifying,
copying, reproducing, or otherwise divulging such confidential information, and
shall hold each other harmless and protect and indemnify the same in the event
of any disclosure by said persons. The terms of this Section 15 shall continue
beyond the term of this Agreement and shall be binding and enforceable even
after the termination of this Agreement.

16. PLURAL/GENDER. Whenever from the context it appears appropriate, each term
stated in either the singular or the plural shall include the singular and the
plural, and pronouns stated in the masculine, the feminine or the neuter gender
shall include the masculine, feminine and neuter. The term "person" means any
individual, corporation, partnership, trust or other entity.

17. SEVERABILITY. If any provision of this Agreement, or the application of such
provision to any person or circumstance, shall be held invalid, the remainder of
this agreement, or the application of such provision to persons or circumstances
other than those to which it is held invalid, shall not be affected thereby.

18. COUNTERPARTS. This Agreement may be executed in several counterparts, each
of which shall be deemed an unlawful but all of which, when taken together,
shall constitute one and the same instrument. It shall not be necessary for all
parties to execute the same counterpart hereof.

19. WAIVER. No failure on the part of either party to exercise, and no delay in
exercising any right or remedy hereunder shall operate as a waiver thereof, nor
shall any single or partial exercise of any right or remedy hereunder preclude
any other or further exercise thereof or the exercise of any other right or
remedy granted hereby or by law.

20. NOTICE. Unless otherwise provided, any notice to be given hereunder shall be
effective on the fifth day after dispatch. Such notice shall be sent by first

                                   SCHEDULE B

                    NETWORK SERVICES VIP TERMS AND CONDITIONS

1. UUNET exercises no control whatsoever over the content of the information
passing through UUNET. Except as otherwise provided for in Section Ten of the
Network Services Agreement attached hereto, UUNET makes no warranties of any
kind, whether expressed or implied, for the service it is providing. UUNET also
disclaims any warranty or merchantability or fitness for a particular purpose.
UUNET will not be responsible for any damage Reseller suffers. This includes
loss of data resulting from delays, nondeliveries, misdeliveries, or service
interruptions caused by Reseller's own negligence or Reseller's errors or
omissions. Use of any information obtained via UUNET is at the user's own risk.
UUNET specifically denies any responsibility for the accuracy or quality of
information obtained through its services.

2. UUNET's network may be used only for lawful purposes. Use of UUNET's network
for lawful commercial purposes is both permitted and encouraged. Transmission of
any material in violation f any applicable law is prohibited. This includes, but
is not limited to: copyrighted material, material which is threatening or
obscene, or material protected by trade secret. Any access to other networks
connected to UUNET's network must comply with the rules appropriate for the
other network. Reseller agrees to indemnify and hold harmless UUNET from any
claims resulting from Reseller's use of the service or the use of the service by
any of Reseller's customers or others throughout Reseller's chain of
distribution, including end users, which damages UUNET or another party.

3. Resale to other individuals and organizations is permitted, but they may not
further resell the services.

4. Payment is due thirty (30) days after date of invoice. Accounts are in
default if payment is not received within thirty (30) days after date of
invoice. Accounts unpaid sixty (60) days after date of invoice may have service
interrupted. Such interruption does not relieve Reseller from the obligation to
pay the monthly charge. Only a written request to terminate service relieves it
of the obligation to pay the monthly account charge. Accounts in default are
subject to an interest charge of one-and-one-half percent (1.5%) per month on
the outstanding balance. If Reseller's state does not allow an interest rate of
one-and-one-half-percent (1.5%), then the maximum allowable rate will be
charged. Reseller agrees to pay UUNET its reasonable expenses, including
attorney and collection agency fees, incurred in enforcing UUNET's rights under
this Agreement for money due and owing.

5. These Terms and Conditions supersede all previous representations,
understandings or agreement sand shall prevail notwithstanding any variance with
terms and conditions of any order submitted. Use of UUNET's network constitutes
acceptance of these Terms and Conditions.

                                   SCHEDULE C

                TECHNICAL AGREEMENT FOR NETWORK INTEROPERABILITY

1. Reseller agrees to secure a minimum 11 connection from UUNET and operate its
own Radius server. Such server will perform user validation functions, and
will be maintained in a secure environment. Reseller also will maintain this
server with reasonably current versions of the Radius protocols as provided
by UUNET.

2. Reseller agrees to use software and procedural safeguards to insure that
only accurate routing information for networks to be used by Reseller's
customers is transmitted from Reseller's Radius server into UUNET's network and
to use best efforts to immediately remedy any problems leading to transmission
of incorrect routing information.

3. Reseller agrees to assign each end user customer a unique identification
number for billing purposes, and to reasonably cooperate with UUNET in
establishing the structure of this identification number.

4. Reseller and UUNET each agree to cooperate with the other in identifying and
resolving any security infringements which involve Reseller's customers and
UUNET's network.

5. It is recognized and agreed that any billing data supplied on an interim
basis (more frequently than monthly) is an estimate and may not be relied upon
for 100% accuracy.

                                 AMENDMENT NO. 1

This Amendment No. 1 ("Amendment") to the Virtual Internet Provider (VIP)
Agreement between UUNET Technologies, Inc. ("UUNET") and I-Pass Alliance, Inc.
("Reseller"), dated January 8, 1997 ("Agreement") is made as of the date of the
second signature below.

The parties agree to add the following Sections to Schedule A of the Agreement
as follows:

5.      RADIUS ACCOUNTING AND PRICING

        UUNET will provide Radius Accounting, a method of measuring End Users'
        use of the services consisting of login and logout statistics of each
        End User, at Reseller's written request. Reseller has the sole
        responsibility to analyze these statistics to identify and investigate
        duplicate log-ins and take appropriate action. The statistics are not to
        be used as a method for calculating monthly charges for UUNET services,
        as the definitive calculation of Reseller's monthly charges will be set
        forth in the invoice provided Reseller on a monthly basis.

        The Monthly Fee for Radius Accounting will be waived for six (6) months
        from the date of the second signature below provided that monthly
        charges paid by Reseller to UUNET increase by [*] over the charges in
        the month prior to execution of this Amendment during each of the six

                                 AMENDMENT NO. 2

This Amendment No. 2 ("Amendment") to the Virtual Internet Provider Agreement
("VIP") between UUNET Technologies, Inc. ("UUNET") and I-Pass Alliance, Inc.
("Reseller"), dated January 9, 1997 ("Agreement") is made as of the date of the
second signature below ("Effective Date"). The Amendment also amends the
CompuServe Network Services Agreement for Managed Service Providers (MSP) dated
November 4, 1997 ("CompuServe NSA").

Whereas, the parties desire to amend the Agreement and the CompuServe NSA,

Whereas, UUNET is the successor in interest to CompuServe Network Services,
Inc., and has assumed the obligations and rights of CompuServe, Inc. under the
CompuServe NSA;

Now, therefore, in accordance with procedures for amendment of the Agreement and
the CompuServe NSA set forth therein, and in consideration of the foregoing and
the mutual agreements herein set forth, the parties hereby agree as follows:

The parties agree as follows:

1.      The parties agree to extend the term of the Agreement and the term of
        the CompuServe NSA for an additional three (3) years from the Effective
        Date of this Amendment, which terms shall hereafter remain coterminous
        and upon the expiration of such agreements shall be automatically
        renewed for an additional one year term, provided that neither party has
        delivered to the other a written notice of intent not to renew for the
        forthcoming term not less than 60 days in advance of the end of the
        then-current term.

2.      Section 7 of the Agreement shall be replaced with the following:

        This Agreement may not be terminated by either party except that either
        party may terminate this Agreement if the other party materially
        breaches the terms of this Agreement and does not cure the breach within
        sixty (60) days after receipt of written notice of such breach, which
        notice describes such breach in reasonable detail. Upon termination or
        expiration of this Agreement for any reason other than Reseller's breach
        of Reseller's payment or confidentiality obligations, at Reseller's
        request the parties shall continue to perform all of their obligations
        and maintain all of their rights under the Agreement for a phase-out
        period of thirty (30) days from the date of termination or expiration.
        However, if Reseller violates the Acceptable Use Policy in Section 2 of
        Schedule B, or becomes aware of such a violation, and in either event
        does not immediately act to remedy such violation when it becomes aware
        of it, UUNET may terminate this Agreement without penalty with thirty
        (30) days written notice, provided that service may be suspended without
        prior notice to the extent necessary for UUNET to respond to a court or
        government demand, or to preserve the integrity or normal operation of
        the UUNET Network. Reseller shall be notified promptly of any material
        suspension of service undertaken pursuant to the previous sentence.

3.      Section 1 of Schedule A of the Agreement shall be replaced with the
        following:

4.      Section 2 of Schedule A of the Agreement shall be replaced with the
        following:

        Reseller agrees to a total Monthly Minimum Amount of [*] per month
        for dial-up Internet access services from UUNET. If in any month the sum
        of the actual charges for dial-up Internet access service under the
        Agreement and the CompuServe NSA is less than [*] then Reseller
        shall pay the applicable Monthly Minimum Amount in lieu of actual
        charges.

5.      In consideration for the Monthly Minimum Amount agreed to in Section 3
        of this Amendment, UUNET will reduce the basic Rate Per Hour set forth
        in Section 3.1 of the CompuServe NSA to [*] per hour. Surcharges and
        other fees in the CompuServe NSA shall not be modified by this
        Amendment.

6.      The following shall be included in Section 2 of the Schedule B of the
        Agreement

All use of the service or the UUNET Network shall comply with the UUNET
Acceptable Use Policy ("Policy") for the country in which the service is used,

such revised Policy will be included with Reseller's monthly invoice in the
month following the change. Reseller agrees to develop, maintain, and require
its customers to comply with an acceptable use policy containing terms at least
as restrictive as the Policy, as applicable, including any subsequent
modifications.

7.      Section 3 of Schedule B of the Agreement shall be replaced with the
        following:

        Notwithstanding any other provision of this Agreement, Reseller shall

        more tiers of subdistributors, and to grant the right to its customers
        to do the same, provided that all such customers or subdistributors
        comply with the applicable terms of this Agreement.

activities within 4 working hours of notification, provided the notification is
received, and the call-out can be made during the normal business day of the
Scitor ITS Sub-Contractor nearest to the affected Location, and provided, also
that the affected Location is within a 45 mile radius of said center ("Normal
Service"). Remedial service on Equipment other than Normal Service shall be

possible, taking into account availability of service personnel, the time and
date of Customer's notification and the country concerned.

        6.10 Scitor ITS shall not be responsible for Service faults, nor shall
Scitor ITS be obliged to comply with its obligations under Clause 6.9, if such

carried out by non Scitor ITS personnel; (c) modifications, to the Equipment
which have not been approved by the Equipment manufacturer or carried out by
personnel unapproved by Scitor ITS; (d) improper treatment to the Equipment,

conditions; or (e) accident or negligence on the part of Customer or any Force
Majeure event. Any site visits or repairs made necessary by the events specified

cause Customer to incur increased charges for the Service at the affected
Location, such charges to be commensurate with the cost to Scitor ITS of
restoring or repairing the Service.

7.      SOFTWARE

        Customer is hereby granted non-exclusive and non-transferable licenses
to use Software strictly in performing this Agreement. The Software and any
intellectual property rights of whatever nature in the Software are and shall
remain vested in Scitor ITS or an Associated Company of Scitor ITS and nothing
contained in this Agreement shall convey any ownership interest in the Software
to Customer. Customer acknowledges that the provision of Software is made by
Scitor ITS strictly for use in conjunction with the Service and Customer agrees
not to produce, copy, alter, modify, or add to the Software or any part thereof,
nor to attempt or to

        8.2 Subject to this Clause 8.2, Scitor ITS warrants that the Service
will not infringe third party intellectual property rights in any country where

infringement and will pay resulting costs and damages finally awarded by a
court, provided that Customer: (a) promptly notifies Scitor ITS in writing of
the claim and; (b) gives Scitor ITS sole control of the defense and all related
settlement negotiations. Scitor ITS will either procure the right for Customer
to continue using the Service (including the part of the Service that has

no cost to Customer. Scitor ITS will have no liability for any claim based upon
the combination, operation or use of the Service with equipment, data or
software not supplied by Scitor ITS if the cause of the infringement cannot be
clearly identified. Notwithstanding anything else contained in this Clause 8.2,
in no event shall Scitor ITS's liability to Customer in respect of Equipment or
software not proprietary to Scitor ITS or an Associated Company of Scitor ITS
exceed any intellectual property infringement warranties provided to Scitor ITS
or an Associated Company of Scitor ITS by third party equipment and software
suppliers.

        8.3 Customer and Scitor ITS acknowledge that they will receive
confidential information and trade secrets ("Confidential Information") from

available at the time of the disclosure or subsequently becomes publicly
available through no fault of Customer or Scitor ITS or is rightfully acquired
from a third party who is not in breach of an agreement to keep such information
confidential.

entitled to invoice Customer a connection and project management charge for the
new Location as agreed by the Parties;

        2.3 Customer may remove a Location if Customer is unable to conduct its
business at that Location due to Force Majeure. This provision may only be

3.      Any cancellation of Service at a Location under Clauses 2.2 and 2.3
        above (but not pursuant to Clause 2.1 of this Attachment 3 where there
        are no conditions other than as set forth in the Agreement at the
        appropriate clauses) shall be conditional on the following:

        3.1 Customer must give Scitor ITS at least 60 days prior written notice;

        3.2 Customer shall remain responsible for any Tail Circuit charges

        3.3 Customer shall pay to Scitor ITS a disconnection fee of [*] per
canceled Location;

        3.4 Customer shall remain responsible for the duration of the term of

transfer shall not affect the rental term.

CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY BRACKETS,
HAS BEEN OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
COMMISSION PURSUANT TO RULE 406 OF THE SECURITIES ACT OF 1933, AS AMENDED.


                                 AMENDMENT NO. 2
                 TO THE MANAGED DATA NETWORK SERVICES AGREEMENT
                            NO. MDNS/US/TPAS/09/96/99
                                  ("AGREEMENT")
                BETWEEN EQUANT NETWORK SERVICES, INC. ("EQUANT")
                                       AND
                       I-PASS ALLIANCE, INC. ("CUSTOMER")

This Amendment No. 2 ("Amendment") is made by and between EQUANT and Customer
and shall be effective as of October 1, 1998 ("Effective Date").

In consideration of the covenants, premises and agreements set forth below, and
in consideration of those set forth in the Agreement, which this Amendment
supplements and modifies, the parties do hereby agree as follows:

        1.      Year 2000 Compliance

        The Agreement is hereby amended by renumbering the existing Clause 7 as
        Clause 7.1 and inserting the following as new Clause 7.2:

                "7.2 EQUANT warrants that all software (including the Software
                and any firmware), hardware, networks and equipment (together
                "Systems") over which it has Control (as defined below) used in
                connection with the provision, running and operation of the
                Service ("EQUANT Systems") will be Year 2000 Compliant (as
                defined below) by December 31, 1998. In respect of relevant
                Systems that EQUANT does not Control, including without
                limitation, all relevant Systems operated by, or proprietary to,
                telecommunications operators, EQUANT shall endeavor to obtain a
                Year 2000 Compliance statement from the relevant suppliers and
                shall advise Customer as to the results thereof and thereafter
                keep Customer informed of changes in status. EQUANT shall use
                reasonable endeavors to mitigate any fault in the Service caused
                by the non-Year 2000 Compliance of any Systems it does not
                Control, but shall not be liable to Customer for any loss or
                damages in the event that any such non-Year 2000 Compliance
                causes a fault in, or the non-availability of, the Service.

                7.2.1 Customer shall ensure that any of its programs or Systems
                or data into which the Systems used in the provision, running
                and operation of the Service will communicate or integrate are
                Year 2000 Compliant.

                7.2.2 EQUANT shall not be liable for any faults in or
                non-availability of the Service or Systems provided under this
                Agreement which arise out of non-Year 2000 Compliance except to
                the extent expressly provide above. Furthermore, EQUANT shall
                have no liability under the above warranty for any breach
                arising from the use of non-Year 2000 Compliant Systems or data
                with EQUANT Systems.

<PAGE>   29

                7.2.3 For the purposes of this Agreement, EQUANT shall be deemed
                to "Control" a System if it (or any Associated Company of
                EQUANT) operates (or has given the Customer the right to use
                under this Agreement) and owns the intellectual property rights
                to the System; and "Year 2000 Compliant/ce" means Year 2000
                conformity as that term is defined in DISC PD2000-1 published by
                the British Standards Institution."

        2.      EXCLUSIONS AND LIMITATIONS OF LIABILITY

        The Agreement is hereby amended by deleting Clause 10.3 in its entirety
        and substituting the following therefor:

                "EXCEPT FOR SHORTFALL CHARGES RESULTING FROM THE FAILURE TO
                SATISFY THE MINIMUM REVENUE COMMITMENTS SET FORTH IN ATTACHMENT
                2, NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY FOR ANY
                INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES HOWSOEVER
                ARISING, INCLUDING BUT NOT LIMITED TO, ANY DAMAGES FOR LOST
                TIME, INCOME, REVENUE, CLIENTS' GOODWILL, PROFITS, OR OTHER
                SIMILAR ITEMS, OR ANY BUSINESS INTERRUPTION OF ANY KIND, EVEN IF
                THE OTHER PARTY HAS BEEN INFORMED OF THE POSSIBILITY OF SUCH
                DAMAGES IN ADVANCE."

        3.      MINIMUM VOLUME COMMITMENT

        The Agreement is hereby amended by adding the following new Clause 8 to
        Attachment 2:

                "8. MINIMUM VOLUME COMMITMENT

                During each "Commitment Period" specified below (as measured
                from the Effective Date of this Amendment), Customer shall
                satisfy the corresponding minimum volume commitment based on
                Customer's combined usage of X.25, X.28, and Remote LAN Access
                services (each such minimum volume commitment referred to as an
                "MVC"):

                Each MVC shall be calculated after application of all discounts
                using Customer's monthly recurring Port, Dial Access, and Remote
                LAN Access service charges and usage charges set forth in this
                Attachment 2, excluding one-time charges, Tail

                Charges ("Qualifying Charges").

                Should the actual Qualifying Charges invoiced to Customer during
                any Commitment Period be less than the applicable MVC
                ("Shortfall"), EQUANT shall invoice, and Customer shall pay, the
                Shortfall in accordance with Clause 9 of the Agreement.

                Alternatively, EQUANT and Customer may agree to extend the
                Initial Term for such a period so as to cover all or part of the
                Shortfall ("Grace Period"). Notwithstanding the foregoing, in no
                event shall the Grace Period exceed six (6) months. EQUANT shall
                invoice, and Customer shall pay, any Shortfall balance remaining
                at the end of the Grace Period in accordance with Clause 9 of
                the Agreement."

        4.      PUBLIC X.28 CONNECTION CHARGES

        Attachment 2 of the Agreement is hereby amended by deleting the Schedule

                     OEM SERVICE PROVIDER LICENSE AGREEMENT
                               RSA SECURITY, INC.


Thank you for choosing to do business with us. This Agreement has the purpose of
licensing you the right to (i) incorporate the RSA Software into your products
and (ii) use and/or distribute to end users the RSA Software solely as
incorporated into such products for the purpose of providing Your service. In
return, You agree to pay RSA the license fees described in this Agreement (or
its attachments) which typically comprise an initial payment of license fees,
plus ongoing royalties, but, alternatively may consist of annual license fee
amount, paid-up license fee amounts or other arrangements as described in this
Agreement. This license is for object code only. Maintenance and support for the
RSA Software licensed, if elected, is under separate terms and conditions. This
License Agreement is to be construed and interpreted in accordance with this
general purpose, though any conflict between this general purpose and the
express terms found in this Agreement shall be resolved in favor of the express
terms.

ENTERPRISE NAME ("YOU"):  iPass Inc.   JURISDICTION OF INCORPORATION: California

STREET ADDRESS:  3800 Bridge Parkway   STATE & ZIP CODE:  California 94065

CITY:  Redwood Shores

ENTERPRISE LEGAL CONTACT (NAME & TITLE):

AGREEMENT NUMBER:  0200-iPA-SER-2

This LICENSE AGREEMENT (the "Agreement"), effective as of the later date of
execution ("Effective Date"), is entered into by and between RSA Security, Inc.,
a Delaware corporation ("RSA"), having a principal address at 2955 Campus Drive,
Suite 400, San Mateo, CA 94403-2507, and the Enterprise identified above.

1. DEFINITIONS

        The following terms when used in this Agreement shall have the following
meanings:

        1.1 "DISTRIBUTOR" means a dealer or distributor in the business of
relicensing or distributing Client Licensed Products to End User Customers,
directly or through one or more Distributors, by virtue of authority granted by
You for the purpose of providing the Licensed Service. Client Licensed Products
relicensed or distributed by a Distributor shall bear Your trademarks and
service marks and shall not be privately labeled by such Distributor or other
parties. A Distributor shall have no right to add to or modify any part of a
Licensed Product.

        1.2 "END USER CUSTOMER" means a person or an entity receiving the RSA
Software as part of a Client Licensed Product from You or a Distributor for
personal or internal use to obtain the Licensed Service and primarily not for
resale, redistribution or other transfer of such Client Licensed Product to any
other person or entity.



                                       1.
<PAGE>   2

        1.3 "LICENSED PRODUCT(S)" means one or more of Your products or product
groups identified in the attached "License/Product Schedule Exhibit" which has
been or will be developed by You and which incorporates in any manner any
portion of the RSA Software. A Licensed Product (i) must represent a significant
functional and value enhancement to the RSA Software, (ii) shall not expose or,
directly or indirectly, pass through any APIs, and (iii) shall not be a security
add-on or "bolt-on," the primary purpose of which is providing security to a
third party's product. A Licensed Product consists of a client component
("Client Licensed Product") and a server component ("Server Licensed Product").
Each component of a Licensed Product shall be capable of operating only in
conjunction with the other component. The Server Licensed Product must be owned
and operated by You at Your site, and You shall have no right to change a
license fee or comparable fee for distribution of the Client Licensed Product.

        1.4 "LICENSED SERVICE(S)" means one or more of Your services identified
in the attached "License/Product Schedule Exhibit" which has been or will be
developed by You and which uses or is supported by the Licensed Products. The
Licensed Service must represent a significant functional and value enhancement
to the RSA Software, such that the primary reason for an End User Customer to
obtain the Licensed Service is other than the right to use the RSA Software.
Only You may provide the Licensed Service.

        1.5 "RSA SOFTWARE" means RSA's proprietary software identified on the
attached "License/Product Schedule Exhibit" (and including only those algorithms
listed therewith), as further described in the User Manual(s) associated
therewith.

        1.6 "UPDATES" means any new version of the RSA Software designated by a
progressing of the release number (either right or left of the decimal point)
following the version initially shipped hereunder.

        1.7 "USER MANUAL" means the most current version of the user manual
and/or reference manual customarily supplied by RSA to entities who license the
RSA Software.

        1.8 "SUBSCRIBER" means a person or entity to whom a copy/unit of the
Client Licensed Product has been distributed and who has paid You any cash or
in-kind consideration at any time for the Licensed Service, whether as use,
transaction, subscription, or service fees or any comparable fees based on or
involving the use of the Licensed Service. You shall have no right to charge a
license fee or comparable fee for distribution of the Client Licensed Product.

2. LICENSES

        2.1 LICENSE GRANT. During the term of this Agreement and within the
Field of Use limitation set forth in the "License/Product Schedule Exhibit"
attached hereto RSA hereby grants You a non-exclusive, non-transferable license
to:

             2.1.1 (i) incorporate the RSA Software in object or byte code
format into a Licensed Product; (ii) reproduce and have reproduced the RSA
Software in object or byte code format as incorporated in a License Product and
as reasonably needed for inactive backup or archival purposes; (iii) license or
otherwise distribute the RSA Software in the Territory as incorporated in a
Client Licensed Product (if distribution of such Licensed Product is not
prohibited in the attached "Licensed/Product Schedule Exhibit") to End User
Customers, directly



                                       2.
<PAGE>   3

or indirectly through one or more Distributors; and (iv) reproduce, have
reproduced and distribute the RSA Software in the Territory as incorporated in a
Licensed Product to Your employees at Your site(s) and for use by such employees
solely for the purpose of providing the Licensed Service to End User Customers
or supporting the Licensed Service.

             2.1.2 (i) use the User Manual to support End User Customers and the
Licensed Service; (ii) modify and incorporate any or all of the User Manual in
Licensed Product and Licensed Service documentation; (iii) reproduce, have
reproduced and distribute in the Territory such portions of the User Manual as
incorporated in Licensed Product documentation to Your employees at Your site(s)
and for use by such employees solely for the purpose of providing the Licensed
Service to End User Customers or supporting the Licensed Service; and (iv)
reproduce and have reproduced and distribute in the Territory such portions of
the User Manual as incorporated in Licensed Product and Licensed Service
documentation to End User Customers.

        2.2 LIMITATIONS ON LICENSES. Notwithstanding the generality of the
foregoing: You may not in any way sell, lease, rent, license, sublicense or
otherwise distribute the RSA Software, except as part of a Client Licensed
Product whose distribution is not prohibited on the attached "License/Product
Schedule Exhibit". Such distribution must be for the sole purpose of providing
the Licensed Service. The RSA Software may only be accessed by the functionality
of the Licensed Product in which it is included, and a Licensed Product shall
not make the RSA Software directly accessible to End User Customers or to
products other than the Licensed Product, or otherwise expose an API. Nothing in
this Agreement grants You any rights, license or interest with respect to source
code of the RSA Software. You shall not modify, translate reverse engineer,
decompile or disassemble the RSA Software or any part thereof or otherwise
attempt to derive source code or create derivative works therefrom, and shall
not authorize any third party to do any of the foregoing.

3. OWNERSHIP/PROPRIETARY RIGHTS

        3.1 RSA SOFTWARE TITLE. Except for the limited licenses expressly
granted in Section 2.1 and as further limited by Section 2.2, RSA does not by
this Agreement grant You any right, title or ownership interest in or to the RSA
Software or in any related patents, trademarks, copyrights of proprietary or
trade secret rights. Similarly, RSA receives no right, title or ownership
interest in any of Your products by way of this Agreement.

        3.2 RSA COPYRIGHT NOTICES. You agree not to remove, alter or destroy any
proprietary, trademark or copyright markings or notices placed upon or contained
within the RSA Software, User Manuals or any related materials or documentation.
You further agree to insert and maintain within every Licensed Product and any
related materials or documentation a copyright notice in Your name.

        3.3 TRADEMARKS. Except as provided in Section 6.1, You shall acquire no
rights of any kind in or to any RSA trademark, trade name, logo or product
designation under which the RSA Software was or is marketed and shall not make
any use of the same for any reason except as expressly authorized by this
Agreement or otherwise authorized in writing by RSA. You shall cease to use the
markings, or any similar markings, in any manner on the expiration or other
termination of this Agreement.

4. LICENSE FEES

        4.1 LICENSE FEES. In consideration of RSA's granting you the license
rights in this Agreement, You agree to pay RSA the license fees and ongoing
royalties (collectively, "License Fees") set forth in the "License/Product
Schedule Exhibit" attached hereto.

        4.2 TERMS OF PAYMENT - GENERAL. License Fees due RSA hereunder shall be
paid to the attention of the Software Licensing Department at RSA's address set
forth above. Payments of all License Fees shall be made in lawful United States
currency and shall in no case be refundable. A late payment penalty on any
License Fees not paid when due shall be assessed at the rate of one percent (1%)
per thirty (30) days, beginning on the thirty-first (31st) day after the delayed
payment was due. All taxes, duties, fees and other governmental charges of any
kind (including sales and use taxes, but excluding taxes based on the gross
revenues or net income of RSA) which are imposed by or under the authority of
any government or any political subdivision thereof on the License Fees or any
aspect of this Agreement shall be borne by You and shall not be considered a
part of, a deduction from, or an offset against License Fees.

        4.3 LICENSES WITH ONGOING ROYALTIES. In the event You have elected to
pay License Fees based on ongoing royalties, as indicated on the attached
"License/Product Schedule Exhibit," You agree to pay the prepaid License Fees
and ongoing royalties as described therein and in accordance with the following:

             4.3.1 PREPAYMENTS AND ONGOING ROYALTY PAYMENT. All prepaid license
fees ("Prepayments") may be offset against on-going royalties accrued until the
Prepayments are exhausted. You shall show the application or Prepayments in the
licensing reports provided to RSA pursuant to Section 4.3.2. Ongoing royalties
shall be paid on or before the thirtieth (30th) day after the close of the
calendar quarter during which such royalties accrued. Ongoing royalties shall
accrue with respect to the Licensed Service upon the date of invoice for the
Licensed Service to an End User Customer or the date payment therefor was first
payable to You, whichever occurs first. To the extent the License Fees described
in the "License/Product Schedule Exhibit" are based on Service Revenue, "Service
Revenue" means the gross amount of all cash, in-kind or other consideration
receivable by You at any time in consideration of providing the Licensed
Service, whether as use, transaction, subscription, or service fees, or any
comparable fees based on or involving the use of the Licensed Service. For the
purposes of determining Service Revenue, the amount of in-kind or other non-cash
consideration receivable by You shall be deemed to have a dollar value equal to
the standard price (as listed in Your published price schedule on the date the
Licensed Service is provided) for the Licensed Service, less all cash paid.

             4.3.2 LICENSING REPORT AND RECORDS. You agree to provide to RSA on
or before the thirtieth (30th) day after the close of each calendar quarter
during the term of this Agreement (even if no royalty amounts have accrued or
are to be paid in such period) a report in reasonable detail setting forth the
calculation of License Fees due hereunder and signed by a responsible officer.
The report shall include, at a minimum, the following information with respect
to the relevant quarter: (i) the total Service Revenue accrued; (ii) the
relevant royalty rate applied to the Service Revenue; (iii) credit taken against
any Prepayments; and (iv) the total License Fees payable. Whether or not You
have elected to pay License Fees based on ongoing



                                       4.
<PAGE>   5

royalties, You agree to maintain reasonable records relating to the Licensed
Products distributed, License Services provided and License Fees accrued and
paid for a period of five (5) years following the relevant dates. RSA shall have
the right, at its sole cost and expense, to have an independent certified public
accountant conduct during normal business hours (but not more than once in any
twelve (12) month period) an audit of Your records to verify compliance with the
terms of this Agreement. In the event such an audit discloses a discrepancy
between the amounts owed and the License Fees actually paid, You will be
invoiced or credited for any future amounts owed by You, as applicable. If any
deficiency in License Fees paid exceeds five percent (5%) of the License Fees
reported by You for any period, You agree to pay the reasonable expenses
associated with such audit, in addition to the deficiency.

             4.3.3 EVALUATION COPIES. You may deliver copies of Client Licensed
Products whose distribution is not prohibited in the attached "License/Product
Schedule Exhibit" to prospective End User Customers on a trial basis for
evaluation purposes only (each, an "Evaluation Copy"). No License Fees shall be
reportable or payable with respect to Evaluation Copies unless and until (i) the
Licensed Service is activated using the applicable Client Licensed Product; (ii)
the End User Customer pays for or is invoiced for the Licensed Service; or (iii)
the End User Customer's use of the Evaluation Copy, for any reason, continues
beyond sixty (60) days, whichever occurs first.

        4.4 MAINTENANCE AND SUPPORT SERVICE. You may elect to receive updates
and other support services for the RSA Software licensed hereunder under a
separate maintenance and support agreement by executing such an agreement and
paying the applicable fee. All Updates provided to You pursuant to such
maintenance and support agreement shall constitute licensed RSA Software under
this Agreement, and such Updates shall be governed by the terms hereof.

5. LIMITED WARRANTY

        5.1 LIMITED WARRANTY. During the initial ninety (90) day term of this
Agreement, RSA warrants that the RSA Software will operate in material
conformance to RSA's published specifications for the RSA Software. RSA does not
warrant that the RSA Software or any portion thereof is error-free. Your
exclusive remedy, and RSA's entire liability shall be correction of any
warranted nonconformity as provided in Section 5.2. This limited warranty and
any obligations of RSA hereunder shall not apply to nonconformities caused by
any unauthorized modification made to the RSA Software.

        5.2 ERROR CORRECTION. In the event You discover an error in the RSA
Software which causes the RSA Software not to operate in material conformance to
RSA's published specifications therefor, You shall submit to RSA a written
report describing such error in sufficient detail to permit RSA to reproduce
such error. Upon receipt of any such written report, RSA will use its reasonable
business judgment to classify a reported error as either (i) a "Level 1
Severity" error, meaning an error that causes the RSA Software to fail to
operate in a material manner or to produce materially incorrect results and for
which there is no workaround or only a difficult workaround; or (ii) a "Level 2
Severity" error, meaning an error that produces a situation in which the RSA
Software is usable but does not function in the most convenient or expeditious
manner, and the use or value of the RSA Software suffers no material impact. RSA
will acknowledge receipt of a conforming error report within two (2) business
days and will use



                                       5.

its reasonable efforts to (A) provide a correction for any Level 1 Seventy error
to You as early as practicable, and (B) include a correction for any Level 2
Severity error in the next release of the RSA Software.

        5.3 DISCLAIMER. EXCEPT FOR THE EXPRESS LIMITED WARRANTY PROVIDED IN THIS
SECTION 5, THE RSA SOFTWARE IS PROVIDED "AS IS" WITHOUT ANY WARRANTY WHATSOEVER.
RSA DISCLAIMS ALL WARRANTIES, EXPRESS, IMPLIED OR STATUTORY, AS TO ANY MATTER

Seal within any Licensed Product such that users thereof are exposed to the RSA
Seal during normal operation of such Licensed Product as follows: In a software
Licensed Product, the RSA Seal shall be featured in such Licensed Product's
startup splash screen and within any security-related dialog windows visible in
the normal operation of the product (e.g., password dialog window). In a
hardware Licensed Product, the RSA Seal shall be visible on the panel of such
Licensed Product most normally viewed by the user. You agree to include the RSA
Seal within related marketing materials including but not limited to printed and
electronic data sheets, direct mail, user documentation, product packaging and
advertisements for the Licensed Products and Licensed Service.

        6.2 REPRESENTATIONS REGARDING RSA SOFTWARE. You are authorized to

        The parties agree to treat as confidential the terms of this Agreement
and any License Fee or accounting information provided by one party to the other
in performance hereof, and the parties agree to use their reasonable efforts to
prevent disclosure thereof to any third party except with the prior written
consent of the other party, or as required by law. This obligation of
confidentiality shall extend for a period of three years following termination
or expiration of this Agreement. Notwithstanding the generality of the
foregoing, either party may disclose the existence of this Agreement and that
You are an OEM of the RSA Software and that any publicly-announced Licensed
Service uses the RSA Software.

8. LIMITATION OF LIABILITY

        IN NO EVENT WILL EITHER PARTY BE LIABLE TO THE OTHER PARTY FOR INDIRECT,

9. INTELLECTUAL PROPERTY INDEMNITY

        9.1 DUTY TO DEFEND. RSA agrees that it shall at its own expense, defend,
or at its option settle, any action instituted against You, and pay any award or
damages assessed against You or agreed by RSA to be paid in settlement resulting
from such action, insofar as the same is based upon a claim that any RSA
Software used in accordance with the terms of this Agreement infringes any
United States copyright, United States trade secret, or a claim that RSA has no
right to license the RSA Software hereunder, provided that You give RSA: (i)
prompt notice in writing of such action; (ii) the right to control and direct
the investigation, preparation, defense and settlement of the action; and (iii)
reasonable assistance and information.

        9.2 RSA OPTIONS. If such an action is made or RSA reasonably determines
in its discretion that such a claim is likely to be made, RSA shall have the
option to (i) obtain the right for you to continue use of the RSA Software; or
(ii) replace or modify the RSA Software so that it is no longer infringing but
functionally equivalent. If RSA determines that neither of these alternatives is
reasonably available, RSA shall have the option to refund the License Fees paid
by You hereunder less depreciation for use assuming straight line depreciation
over a five (5) year useful life and terminate this Agreement.

        9.3 CLAIMS FOR WHICH RSA IS NOT RESPONSIBLE. Notwithstanding the
foregoing, RSA shall have no liability under this Section 9 if the alleged
infringement arises from (i) the use of other than the current unaltered release
of the RSA Software or other than in the manner specified in the relevant User
Manual; or (ii) the combination of the RSA Software with other



                                       7.
<PAGE>   8

equipment or software not provided by RSA, if such action would have been
avoided but for such use or combination. You agree that You shall at Your
expense, defined, or at Your option settle, and hold RSA harmless from any
action instituted against RSA resulting from any infringement claim based upon
either of the foregoing.

        9.4 EXCLUSIVE REMEDY. NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS
AGREEMENT, THE FOREGOING STATES RSA'S ENTIRE LIABILITY AND YOUR EXCLUSIVE REMEDY

approval of the other party.
