to 365; and any amounts owed or to be credited pursuant to Paragraph 4.3.2 shall
be paid at the time in the last Subsequent Year or in the calendar year
immediately following the last Subsequent Year, that such amount is calculated

the event of a default which is not capable of being cured by Tenant, Landlord
shall have the following rights and remedies in addition to any other rights and

                                    (ii)     Landlord shall have rights and
remedies provided by California Civil Code Section 1951.4 ( or any successor
statute), which allows landlord to continue this 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 receiver upon the Landlord's initiative to
protect its interest under this Lease shall not constitute a termination of
Tenant's right to possession; and

                                    (iii)    Landlord shall have the right but
not the obligation to make any payment or perform any act on Tenant's part as
may be required to cure Tenant's default, without waiving its rights based upon
such default by Tenant and without releasing Tenant from any of its obligations.
All sums so paid and all costs incurred by Landlord together with interest
thereon at the Overdue Rate from the date of such payment or the incurrence of
such cost by Landlord, whichever occurs first, shall be paid to Landlord on
demand.

14.      DEFAULT BY LANDLORD

         14.1     Existence of Default. Landlord shall not be deemed to be in
default in the performance of any obligation under this Lease unless and until
it has failed to perform such obligation within thirty (30) days after receipt
of written notice by Tenant to Landlord specifying such failure: provided,
however, that if the nature of Landlord's default is such that more than thirty
(30) days are required for its cure, then Landlord shall not be deemed to be in
default if it commences such cure within the thirty (30) day period and
thereafter diligently prosecutes such cure to completion.

         14.2     Mortgagee's Right To Cure. Tenant shall give any Mortgagee a
copy, by registered mail, of any notice of default served upon Landlord,
provided that Tenant previously has been notified in writing (by way of Notice
of Assignment of Rents and Leases, or otherwise), of the address of such
Mortgagee. If landlord fails to cure such default within the time provided in
this Lease, any such Mortgagee shall have an additional forty-five (45) days
within which to cure such default by Landlord, or if such default cannot be
cured within that time, then such additional time as may be necessary if within
that forty-five (45) day period the Mortgagee has commenced and is pursuing the
remedies necessary to cure such default (including but not limited to
commencement of foreclosure proceedings, if necessary to effect such cure), in
which event this Lease shall not be terminated while such remedies are being so
pursued.

         14.3     Judgment Against Landlord. If Tenant recovers any judgement
against Landlord for a default by Landlord under this Lease, the judgement shall
be satisfied only out of the interest of Landlord in the Building and neither
Landlord nor any of its partners, officers, employees or agents shall be
personally liable for any such default or for any deficiency.

15.      CONDEMNATION

         15.1     Termination Due To Taking. If all or any part of the Premises
are the subject of a Taking, either Landlord or Tenant may, by written notice
given to the other within thirty (30) days of receipt of notice of such Taking,
elect to terminate this Lease as of the date possession is transferred pursuant
to the Taking, provided however, that before tenant may terminate this Lease for
a Taking, such Taking must be of such an extent and nature as to substantially
impede Tenant's use of the Premises. If any part of the Building other than the
Premises shall be the subject of a Taking, Landlord may elect to terminate this
Lease. If there is a Taking of all or a part of the Parking Facilities and the
parking rights granted to Tenant under Paragraph 2.4 are substantially reduced
thereby, Landlord shall have the right to provided replacement parking to
compensate for such reduction within other parking areas serving the Office
Complex. If such replacement parking is not provided, then for a period of
thirty (30) days after Landlord notifies

                                       16
<PAGE>
Tenant that such replacement parking cannot be provided. Tenant shall have the
right to terminate this Lease, effective at a time specified by Tenant not to
exceed thirty (30) days from the date of the notice.

         15.2     No Termination Due To Taking. If a partial Taking of the
Premises does not result in a termination of this Lease, Base Rent, Tenant's
Share of Increased Operating Costs and Tenant's parking rights shall be reduced
in proportion to what the area of the Premises taken bears to the area of the
Premises immediately prior to the Taking. No temporary taking of the Premises or
any part of the Building shall terminate this Lease, except at Landlord's
election, or give Tenant any right to any abatement of Base Rent or Increased
Operating Costs, except that Base Rent and Operating Costs shall be reduced in
accordance with the preceding sentence during that portion of any temporary
Taking of the Premises lasting more than thirty (30) days. Each party hereto
waives the provisions of California Code of Civil Procedure Section 1265.130 (or
any successor statute) allowing either party to file a petition to terminate
this Lease for a partial Taking.

         15.3     Award For Taking. No award for any partial or entire Taking
shall be apportioned, and Tenant hereby assigns to Landlord any and all rights
of Tenant to any portion of the award for a Taking. However, nothing contained
herein shall be deemed to give Landlord any interest in or to require Tenant to
assign to Landlord any award made to Tenant for taking of personal property
belonging to Tenant.

16.       DAMAGE AND DESTRUCTION

         16.1     Partial Damage - Insured. If the Premises or the Building are
damaged by a risk covered under fire and extended coverage insurance insuring

are available to Landlord to pay ninety percent (90%) or more of the cost of
restoration, and provided such restoration by Landlord can be completed within
eight (8) months after the commencement of work in the opinion of a licensed
architect or engineer appointed by Landlord. In such event this Lease shall
continue in full force and effect, except that Tenant shall, so long as the
damage is not due to the act or omission of Tenant, be entitled to an equitable
reduction of Base Rent and Tenant's Share of Excess Building Operating Costs
while such restoration takes place, such reduction to be based upon the extent
to which the damage or restoration efforts materially interfere with Tenant's
use of the Premises.

         16.2     Partial Damage - Uninsured. If the Premises or the Building
are damaged by a risk not covered by such insurance or if the insurance proceeds
available to Landlord are less than eighty percent (80%) of the cost of
restoration, or if the restoration cannot be completed within eight (8) months
after the commencement of work in the opinion of the licensed architect or
engineer appointed by Landlord, then Landlord shall have the option either to
(a) repair or restore such damage, this Lease continuing in full force and
effect, with the Base Rent and Tenant's Share of Excess Building Operating Costs
to be equitably reduced as provided in Paragraph 16.1, or (b) give notice to
Tenant at any time within ninety (90) days after such damage terminating this
Lease as of a date to be specified in such notice, which date shall be not less
than thirty (30) nor more than sixty (60) days after the giving of such notice.
If such notice is given, this Lease shall expire and any interest of Tenant in
the Premises shall terminate on the date specified in such notice. The Base Rent
and Tenant's Share of Excess Building Operating Costs during the period prior to
the termination shall be reduced as provided in Paragraph 16.1 and paid up
through the date of termination.

         16.3     Total Destruction. If the Premises are totally destroyed or in
Landlord's judgment the Premises cannot be restored as required herein under
applicable laws and regulations, notwithstanding the availability of insurance
proceeds, this Lease shall be terminated effective as of the date of the damage.

         16.4     Landlord's Obligations. Any restoration by Landlord pursuant
to Paragraphs 16.1 or 16.2 shall be commenced as soon as reasonably possible
after the date of damage and prosecuted diligently to completion at the earliest
possible date. Landlord shall not be required to carry insurance of any kind on
Tenant's property and shall not be required to repair any injury or damage
thereto by fire or other causes, or to make any restoration or replacement of
any paneling, decorations, partitions, ceilings, floor covering, office fixtures
or any other improvements or property installed in the Premises by or at the
direct or indirect expense of Tenant (other than building standard tenant
improvements), and Tenant shall be required to restore or replace same in the
event of damage. Tenant shall have no claim against Landlord for any loss
suffered by reason of any such damage, destruction, repair or restoration.
Notwithstanding anything to the contrary contained in this section, Landlord
shall have no obligation to repair, reconstruct or restore the Premises with
respect to damage or destruction as described in this section occurring during
the last twelve (12) months of the Term.

         16.5     Waiver by Tenant. Tenant shall have no right to terminate this
Lease as a result of any statutory provisions now or hereafter in effect
pertaining to the damage and destruction of the Premises or the Building, except
as expressly provided herein, and Tenant expressly waives the provisions of
California Civil Code Sections 1932(2) and 1933(4) with respect to any damage or
destruction of the Premises.

         18.1 Estoppel Certificates. Within ten (10) days following any written
request Landlord may make from time to time, Tenant without any charge therefor,
shall execute, acknowledge and deliver a statement certifying: (a) the
Commencement Date of this Lease; (b) the fact that this Lease is unmodified and
in full force and effect (or, if there have been modifications hereto, that this
Lease is in full force and effect, as modified, and stating the date and nature
of such modifications); (c) the date to which the rent and other sums payable
under this Lease have been paid; (d) the fact that there are no current defaults
under this Lease by either Landlord or Tenant except as specified in the
statement; and (e) such other matters as may be reasonably requested by
Landlord. Landlord and Tenant intend that any statement delivered pursuant to
this

                                       23

<PAGE>

paragraph may be relied upon by a mortgagee, beneficiary, purchaser or
prospective purchaser of the Building or any interest therein. Tenant's failure
to deliver any such statement within said ten (10) day period shall constitute a
material default, and Tenant shall indemnify and hold Landlord harmless form and
against any and all liability, loss, cost, damage and expense which Landlord may
sustain or incur as a result of or in connection with Tenant's failure or delay
in delivering such statement. If Landlord elects to sell the Building or to
obtain loans secured by a lien on the Building, Tenant, promptly after demand,
shall provide to any such purchaser or lender financial statements of Tenant
reasonably required by the purchaser or lender. The financial statements so
provided shall be kept confidential as to any parties other than the purchaser
or lender.

         18.2 Surrender of Premises. A voluntary or other surrender of this
Lease by Tenant or the mutual cancellation of this Lease shall not work a merger
and shall, at the option of Landlord, terminate all or any existing subleases or
subtenancies, or may, at the option of Landlord, operate as an assignment to it
of any or all such subleases or subtenancies.

         18.3 Light and Air. No diminution of light, air or view by any
structure which may hereafter be erected (whether or not by Landlord) shall
entitle Tenant to any reduction of rent under this Lease, result in any
liability of Landlord to Tenant, or in any other way affect this Lease.

         18.4 Waiver. If either Landlord or Tenant waives the performance of any
term, covenant or condition contained in this Lease, such waiver shall not be
deemed to be a waiver of the term, covenant or condition itself or a waiver of
any subsequent breach of the same or any other term, covenant or condition
contained herein. Furthermore, the acceptance of rent by Landlord shall not
constitute a waiver of any preceding breach by Tenant of any term, covenant or
condition of this Lease, regardless of Landlord's knowledge of such preceding
breach at the time Landlord accepts such rent. Failure by Landlord to enforce
any of the terms, covenants or conditions of this Lease for any length of time
shall not be deemed to waive or to decrease the right of Landlord to insist
thereafter upon strict performance by Tenant. Waiver by Landlord of any term,
covenant or condition contained in this Lease may only be made by a written
document signed by Landlord.

         18.5 Attorneys' Fees. In the event that any action or proceeding
(including arbitration) is brought to enforce or interpret any term, covenant or
condition of this Lease on the part of Landlord or Tenant, the prevailing party
in such action or proceeding (whether after trial or appeal) shall be entitled
to recover from the party not prevailing its expenses therein, including
reasonable attorneys' fees and all allowable costs. If Landlord is made a party
to any action or proceeding commenced by a third party due to any
actual or alleged act or omission of Tenant or Tenant's agents, employees,
contractors, invitees or subtenants, Tenant shall indemnify and hold Landlord
harmless from all costs incurred in such action or proceeding, including
reasonable attorneys' fees. If Tenant requests Landlord's consent to, approval
of or signature on any instrument or agreement which would alter or affect
Landlord's legal rights and duties, Tenant shall reimburse Landlord upon demand
for Landlord's reasonable attorneys' fees incurred in connection with the review
and evaluation of the requested action.

         18.6 Notices. Any notice required or permitted under this Lease shall
be in writing and shall be delivered either personally or by depositing same in
the United States Mail, postage prepaid, registered or certified, return receipt
requested, addressed to the intended recipient at such party's address set forth
in the Basic Lease Provisions or at such other address as such party has
theretofore specified by written notice delivered in accordance with this
paragraph. Any notice delivered by mail in the manner specified in this
paragraph shall be deemed delivered on the earlier of the third day following
deposit hereof in the United States Mail or on the delivery date shown on the
return receipt prepared in connection therewith; and any such notice specifying
a default by Tenant shall be deemed sufficient for all purposes under California
Code of Civil

                                       24

<PAGE>

Procedure Section 1161 and 1162, notwithstanding the fact that such notice is
not personally served on Tenant or that such notice does not demand possession
of the Premises as an alternative to Tenant's curing of such default.

         18.7     Merger. Notwithstanding the acquisition (if same should occur)
by the same party of the title and interests of both Landlord and Tenant under
this Lease, there shall never be a merger of the estates of Landlord and Tenant
under this Lease, but instead the separate estates, rights, duties and
obligations of Landlord and Tenant, as existing hereunder, shall remain
unextinguished and continue, separately, in full force and effect until this
Lease expires or otherwise terminates in accordance with the express provisions
herein contained.

         18.8     Substituted Premises. [Deleted]

masculine, where applicable. If there is more than one Tenant, the obligations
imposed under this Lease upon Tenant shall be joint and several. The headings
and titles to the sections and paragraphs of this Lease are used for convenience
only and shall have no effect upon the construction or interpretation of this
Lease.

and all of its provisions. This Lease shall in all respects be governed by and

prior to the expiration or termination of this Lease shall be subject to this
Lease and shall relieve the grantor of all further liability or obligations as
Landlord, except for such liability or obligations accruing prior to the date of
such conveyance. If any Security Deposit has been given to Landlord, Landlord
shall deliver such Security Deposit to Landlord's successor in interest and
thereupon be released of all further liability with regard thereto without the
requirement of any notice thereof to Tenant. Tenant agrees to attorn to
Landlord's successors in interest, whether such interest is acquired by sale,
transfer, foreclosure, deed in lieu of foreclosure or otherwise. Subject to the
foregoing and to the provisions of Section 16, the terms, covenants and
conditions contained herein shall be binding upon and inure to the benefit of
the heirs, successors, executors, administrators and assigns of the parties
hereto.

of non-responsibility, (e) to alter, improve or repair the Premises and any

structures, where required by the work to be performed, all without reduction or
abatement of rent. Tenant hereby waives any claim for damages for any injury to
or interference with Tenant's business or quiet enjoyment of the Premises or any
other loss occasioned by such entry. Landlord shall at all times have a key to
unlock all doors in and about the Premises, excluding Tenant's vaults and
safes, and Landlord shall have the right to use any means which Landlord deems
proper to open said doors in an

                                       25
<PAGE>

emergency, and any such entry to the Premises shall not under any circumstances
be construed or deemed to be a forcible or unlawful entry into the Premises or
a detainer of the Premises or an eviction of Tenant from any portion of the
Premises.

         18.13    Entire Agreement. This Lease, together with its exhibits,
contains all the agreements of the parties hereto and supersedes any previous
negotiations. There have been no representations made by the Landlord or
understandings made between the parties other than those set forth in this Lease
and its exhibits. This Lease may not be modified except by a written instrument
duly executed by the parties hereto.

         18.14    Severability. If any provision of this Lease or the
application thereof to any person or circumstance shall be invalid or
unenforceable to any extent, the remainder of this Lease and the application of
such provision to other persons or circumstances shall not be affected thereby
and shall be enforced to the greatest extent permitted by law.

         18.15    Signs. Tenant shall not place or permit to be placed in or

in any area of the Building not leased to Tenant, such signs, notices, displays
and similar items as Landlord deems appropriate in the proper operation of the
Building.

         18.16    Execution By Landlord. The submission of this document for
examination and negotiation does not constitute an offer to lease, or a
reservation of, or option for, the Premises. This document becomes effective and
binding only upon execution and delivery hereof by Tenant and by Landlord. No
act or omission of any employee or agent of Landlord or of Landlord's broker
shall alter, change or modify any of the provisions hereof.

         18.17    Brokers. Tenant shall hold Landlord harmless from all damages
(including attorneys fees and costs) resulting from any claims that may be
asserted against Landlord by any broker, finder, or other person with whom
Tenant has or purportedly has dealt, except the leasing agent for the Building
duly appointed by Landlord.

         18.18    Name Of Building. Tenant shall not use the name of the
Building for any purpose other than the address of the business to be conducted
by Tenant in the Premises. Tenant shall not use any picture of the Building in
its advertising, stationery or in any other manner so as to imply that the
entire Building is leased by Tenant. Landlord expressly reserves the right at
any time to change the name or street address of the Building without in any
manner being liable to Tenant therefor.

         18.19    Nonrecordability Of Lease. Tenant agrees that in no event
shall this Lease or a memorandum hereof be recorded without Landlord's express
prior written consent, which consent Landlord may withhold in its sole
discretion.

conditions, shall be deemed to be both covenants and conditions. The definitions

remedies of Landlord and Tenant shall, except as otherwise expressly provided,
be cumulative and non-exclusive of any other remedy at law or in equity.

hereunder shall not be affected or impaired because Landlord is unable to
fulfill any of its obligations hereunder or is

                                       26
<PAGE>

delayed in doing so, if such inability or delay is caused by reason of force
majeure, strike, labor troubles, acts of God, acts of government, unavailability
of materials or labor, or any other cause beyond the control of Landlord.

         18.22    Authority. If Tenant is a corporation, each individual

qualified to do business in California and that he is duly authorized to execute
and deliver this Lease on behalf of Tenant and shall deliver appropriate

venture, or other unincorporated association, each individual executing this

consent hereunder, or any written modification or termination of this Lease, by
any general partner of Tenant or any other authorized agent of Tenant, shall be
binding on Tenant.

<PAGE>

6.       FIRST RIGHT TO NEGOTIATE FOR ADDITIONAL SPACE

         GRANT OF RIGHT. During the Term of this Lease and provided Tenant is
         not in default under this Lease, Tenant shall have the right to
         negotiate (the "Negotiation Right") to lease an additional 8,210
         rentable square feet of office space on the Third (3rd ) Floor in the
         Building (the "Spieker Space") as such space becomes available. This
         Negotiation Right shall arise and may be exercised only in accordance
         with the terms of this section.

         NOTICE OF SPACE REQUIREMENT. As Tenant requires additional space,
         Tenant shall notify Landlord in writing of its additional space
         requirements, (the "Requirement Notice"). Tenant's Negotiation Right
         shall become operative upon Landlord's receipt of Tenant's Requirement
         Notice; provided, however, that such Negotiation Right shall be subject
         to any preexisting options, rights of refusal or rights to negotiate
         contained in leases with other tenants. For purposes hereof, a right of
         refusal or right to negotiate in another lease shall be deemed to
         preexist Tenant's Negotiation Right where the same became operative
         prior to the date Tenant delivered its Requirement Notice to Landlord,
         (even though such other lease may have been executed after the
         execution of this Lease). Tenant shall immediately notify Landlord in
         writing of the cessation of any requirement for additional space as set
         forth in a previously delivered Requirement Notice; and such subsequent
         notice shall serve to terminate any previous Requirement Notice and
         Tenant's Negotiation Right.

         EXERCISE OF NEGOTIATION RIGHT. Where Tenant's Negotiation Right is
         operative and not subject to any preexisting options, rights of refusal
         or rights to negotiate in other leases, the following procedure shall
         apply:

         (a) At such time the Spieker Space is available for lease, Landlord
         shall give Tenant notice thereof and shall specify in such notice the
         rent and other basic terms on which Landlord is willing to lease the
         Spieker Space to Tenant (the "Offer Notice"), provided that:

         (b) Tenant shall have a period of ten (10) days after receipt of the
         Offer Notice within which to notify Landlord to writing of Tenant's
         exercise of the Negotiation Right. Should Tenant fail to so notify
         Landlord in writing within said ten (10) day period, Tenant's
         Negotiation Right shall lapse and Landlord shall be free to deal with
         the Spieker Space described in the Offer Notice without regard thereto.

7.       TENANT IMPROVEMENTS

         Landlord shall, at Landlord's sole cost and expense, provide the
         following Tenant Improvements within the Premises:

         1. Conduct an audit of the existing Heating, Air Conditioning and
         Ventilation system on the fourth (4th) Floor. (A copy of which shall be

         otherwise make any necessary repairs

         7. Provide and install soundproofing in two conference rooms and four
         private offices, to be selected by Tenant.

         8. Remove 3/4 height wall at existing entrance to Suite 450

         9. Remove a portion of the demising wall at the west end of Suite 450

         10. Remove glass entry doors to Suite 450 at corridor, and replace with
         a single building standard door

         11. Remove one partition wall between two interior offices.

         Additionally, Landlord shall provide to Tenant a Tenant Improvement
         Allowance of $1.50 per rentable square foot, to be utilized by Tenant
         at Tenant's discretion.

8.       SECURITY DEPOSIT

         By January 15, 1999, Tenant shall pay to Landlord a security deposit in
         the amount of $25,217.61

Landlord may spend or become obligated to spend in exercising Landlord's rights
under Paragraph 13.2 of the Lease (Landlord's Remedies); and/or (c) compensate
Landlord for any expense, loss, or damage that Landlord may suffer because of
Tenant's default. If Tenant fails to renew or replace the LOC at least thirty
(30) days before its expiration, Landlord may, without prejudice to any other
remedy it has, draw on the entire amount of the LOC.

C. LOC SECURITY DEPOSIT. Any amount of the LOC that is drawn on by Landlord but
not applied by Landlord shall be held by Landlord as a security deposit (the
"LOC SECURITY DEPOSIT") in accordance with Paragraph 4 of this Lease.

on any poration of the LOC and/or applies all or any portion of such draw,
Tenant shall, within five (5) business days after demand by Landlord, either (a)
deposit cash with Landlord in an amount that, when added to the amount remaining
under the LOC and the amount of any LOC Security Deposit, shall equal the LOC
Amount then required under this Paragraph 3; or (b) reinstate the LOC to the
full LOC Amount.

currently occupying suite 675 ("Medtronic") has an option to renew their lease
by providing Landlord with notice of intent to renew as of August 4, 2000. In
