PARTIES: This Lease, executed in duplicate at Cupertino, California, on 
December__, 1996, by and between Berg & Berg Enterprises, Inc., a California 
Corporation, and General Surgical Innovations Inc., a California Corporation, 
hereinafter called respectively Lessor and Lessee, without regard to number or 
gender.

USE: WITNESSETH: That Lessor hereby leases to Lessee, and Lessee hires from 
Lessor, for the purpose of conducting therein office, research and development, 
light manufacturing, and warehouse activities, and any other legal activity; 
and for no other purpose without obtaining the prior written consent of Lessor.

PREMISES: The real property with appurtenances as shown on Exhibit A.1 (the 
"Premises") situated in the City of Cupertino, County of Santa Clara, State of 
California, and more particularly described as follows:

     A 30,460 square foot building including all improvements thereto and 
     the right to use up to 116 unreserved parking spaces as shown on 
     Exhibit A.2 ("Phase I") with the addition of approximately 15,000 
     square feet of building and improvements including the right to use 
     approximately 57 additional unreserved parking spaces at the Premises 
     effective September 1, 1998 as shown on Exhibit A.2 ("Phase II"). 
     Phase I and Phase II are collectively referred to herein as the 
     Building (the "Building").  The address for the Building is 10460 
     Bubb Road, Cupertino, California.  Lessee's pro-rata share of the 
     Building is 100%. 

TERM: The term shall be for eighty-four (84) months unless extended pursuant to 
Section 35 of this Lease (the "Lease Term"), commencing on the Commencement 
Date as defined in Section 1, and ending on the day eighty-four (84) months 
thereafter.

RENT: Base rent shall be payable in monthly installments as follows:

                                        Base rent       Estimated CAC*    Total
                                        ---------       --------------    -----
     Months 1 through 12                $46,895            $5,010*       $51,905
     Months 13 through 18               $48,302            $5,010*       $53,312
     Months 19 through 24               $72,100            $7,470*       $79,570

Monthly base rent, net of CAC charges, shall increase by 3% on the annual 
anniversary of the Commencement Date each year during the Lease Term over the 
prior year's rent.  The base rent starting on the 25th month of the Lease Term 
shall be $74,263.

* CAC charges to be adjusted per Common Area Charges Section below. 

Base rent as scheduled above shall be payable in advance on or before the first 
day of each calendar month during the Lease Term.  The term "Rent," as used 
herein, shall be deemed to be and to mean the base monthly rent and all other 
sums required to be paid by Lessee pursuant to the terms of this Lease.  Rent 
shall be paid in lawful money of the United States of America, without offset 
or deduction, and shall be paid to Lessor at such place or places as may be 
designated from time to time by Lessor.  Rent for any period less than a 
calendar month shall be a pro rata portion of the monthly installment.  Upon 
execution of this Lease, Lessee shall deposit with Lessor the first month's 
rent.

SECURITY DEPOSIT: Lessee shall deposit with Lessor the sum of Fifty-One 
Thousand Nine Hundred Five Dollars ($51,905) (the "Security Deposit").  The 
Security Deposit shall be held by Lessor as security for the faithful 
performance by Lessee of all of the terms, covenants, and conditions of this 
Lease applicable to Lessee.  If Lessee commits a default as provided for 
herein, including but not limited to a default with respect to the provisions 
contained herein relating to the condition of the Premises, Lessor may (but 
shall not be required to) use, apply or retain all or any part of the Security 
Deposit for the payment of any amount which Lessor may spend by reason of 
default by Lessee.  If any portion of the Security Deposit is so used or 
applied, Lessee shall, within ten days after written demand therefor, deposit 
cash with Lessor in an amount sufficient to restore the Security Deposit to its 
original amount.  Lessee's failure to do so shall be a default by Lessee.  Any 
attempt by Lessee to



transfer or encumber its interest in the Security Deposit shall be null and 
void.  Upon execution of this Lease by Lessee and Lessor, Lessee shall deposit 
with Lessor the Security Deposit.  Provided Lessee meets all of its obligations 
under this Lease, within 30 days after the termination of this Lease, Lessee 
shall refund the Security Deposit less any amount properly applied under the 
terms of this Lease.

LATE CHARGES: Lessee hereby acknowledges that a late payment made by Lessee to 
Lessor of Rent and other sums due hereunder will cause Lessor to incur costs 
not contemplated by this Lease, the exact amount of which will be extremely 
difficult to ascertain.  Such costs include, but are not limited to, processing 
and accounting charges, and late charges, which may be imposed on Lessor 
according to the terms of any mortgage or trust deed covering the Premises. 
Accordingly, if any installment of Rent or any other sum due from Lessee is not 
received by Lessor or Lessor's designee within ten (10) days after such amount 
is due, Lessee shall pay to Lessor a late charge equal to five (5%) percent of 
such overdue amount.  The parties hereby agree that such late charge represents 
a fair and reasonable estimate of the costs Lessor will incur by reason of late 
payments made by Lessee.  Acceptance of such late charges by Lessor shall in no 
event constitute a waiver of Lessee's default with respect to such overdue 
amount, nor shall it prevent Lessor from exercising any of the other rights and 
remedies granted hereunder.  Notwithstanding the above, Lessee shall not be 
required to pay a late charge if it is the result of a non-recurring unusual 
event such as a accounting error and not occurring more than five (5) times 
during the Lease Term.

QUIET ENJOYMENT: Lessor covenants and agrees with Lessee that upon Lessee 
paying Rent and performing its covenants and conditions under this Lease, 
Lessee shall and may peaceably and quietly have, hold and enjoy the Premises 
for the Lease Term, subject, however, to the rights reserved by Lessor 
hereunder.

COMMON AREA CHARGES: Lessee shall pay to Lessor, as additional Rent, an amount 
equal to Lessee's prorata share of the total common area charges of the 
Premises and Lessee's pro rata share of the total common area charges for the 
Building as defined below (the common area charges for the Premises and the 
common area charges for the Building collectively referred to herein as 
("CAC")).  Lessee shall pay to Lessor as Rent, on or before the first day of 
each calendar month during the Lease Term, subject to adjustment and 
reconciliation as provided hereinbelow, the sum of Five Thousand Ten Dollars 
($5,010), said sum representing Lessee's estimated monthly payment of Lessee's 
percentage share of CAC for 1997.  It is understood and agreed that Lessee's 
obligation under this paragraph shall be prorated to reflect the Commencement 
Date and the end of the Lease Term.

Lessee's estimated monthly payment of CAC payable by Lessee during the calendar 
year in which the Lease commences is set forth above.  At or prior to the 
commencement of each succeeding calendar year term (or as soon as practical 
thereafter), Lessor shall provide Lessee with a description of Lessee's 
estimated monthly payment for CAC which Lessee shall pay to Lessor as Rent. 
Within 120 days of the end of the calendar year and the end of the Lease Term, 
Lessor shall provide Lessee a statement of actual CAC incurred including 
capital reserves for the preceding year or other applicable period in the case 
of a termination year.  If such statement shows that Lessee has paid less than 
its actual percentage, then Lessee shall on demand pay to Lessor the amount of 
such deficiency within 30 days after the receipt of the statement therefore. If 
such statement shows that Lessee has paid more than its actual percentage, then 
Lessor shall, at its option, promptly refund such excess to Lessee or credit 
the amount thereof to the Rent next becoming due from Lessee.  Lessor reserves 
the right to revise any estimate of CAC if the actual or projected CAC show an 
increase or decrease in excess of 10% from an earlier estimate for the same 
period.  In such event, Lessor shall provide a revised estimate to Lessee, 
together with an explanation of the reasons therefor, and Lessee shall revise 
its monthly payments accordingly.  Lessor's and Lessee's obligation with 
respect to adjustments at the end of the Lease Term or earlier expiration of 
this Lease shall survive the Lease Term or earlier expiration.  Notwithstanding 
the above, CAC shall be limited to a maximum increase of 5% over the prior year 
during the initial Lease Term except that this limitation shall not apply to 
(i) tax increases and (ii) the increase resulting from the Substantial 
Completion of the Phase II Improvements.


Page 2



As used in this Lease, CAC shall include, but are not limited to (i) items 
specified as CAC items in Paragraphs 5(b), 6, 16 and 31; (ii) utility costs 
related to the common areas of the Premises as shown on Exhibit A.1; (iii) all 
costs and expenses including but not limited to supplies, materials, equipment 
and tools used or required in connection with the operation and maintenance of 
the Premises; (iv) licenses, permits and inspection fees; (v) all other costs 
incurred by Lessor in maintaining and operating the Premises; (vi) all reserves 
for capital replacements for HVAC, roof, parking lot and exterior painting 
shall not exceed Twelve Thousand Eight Hundred Seventy-Two Dollars ($12,872) 
per year prior to September 1, 1998 and Eighteen Thousand Five Hundred Dollars 
per year after September 1, 1998 or upon Substantial Completion of the Phase II 
Improvements plus annual increases equal to the consumer price index; and (vii) 
an amount equal to five percent (5%) of the aggregate of all CAC, as 
compensation for Lessor's accounting and processing services.  Lessee shall 
have the right to review the books or records related to the CAC applicable to 
this Lease annually.  CAC shall not include any cost related to: (a) hazardous 
or toxic materials unless some type of area-wide assessment is made by a 
government agency or commission; (b) structural defects or construction defects 
or non-compliance with codes existing as of the Commencement Date with respect 
to the Building Shell and Lessee Interior Improvements; (c) leasing and 
marketing costs or costs incurred in enforcing or administering leases (except 
for above accounting); (d) casualty damage covered by insurance or costs for 
which Lessor obtains reimbursement from other sources; and (e) capital 
improvement costs to the extent that Lessee has paid to Lessor reserve amounts 
for such capital improvements.  If Lessee's share of the cost of capital 
improvements due to governmental regulations as provided in Section 9 exceeds 
$5,000, and there are no reserves paid by Lessee to Lessor available for 
Section 9 capital improvements, and the capital improvement is not required due 
to Lessee's particular use of the Premises, such capital improvement cost shall 
be amortized over the estimated useful life of the improvement, not to exceed 
10 years at Wells Fargo prime rate plus one percent (1%).  Lessee shall pay to 
Lessor the amortized costs of such improvement on a monthly basis over the 
Lease Term as part of the CAC.  Notwithstanding the above exceptions to CAC, 
Lessee shall not be relieved of any of Lessee's obligations under this Lease.

COMMENCEMENT DATE MEMORANDUM: When the actual Commencement Date is determined,
the parties shall execute a Commencement Date Memorandum setting forth the
Commencement Date, the expiration date of the Lease Term and any required
adjustments to base rent as provided in this Lease, but failure to do so shall
not affect the continuing validity and enforceability of this Lease, which
shall remain in full force and effect.

IT IS FURTHER MUTUALLY AGREED BETWEEN THE PARTIES AS FOLLOWS:
1. POSSESSION: Possession shall be deemed tendered and the term shall commence
on the first to occur of the following (the "Commencement Date"): (i) the Phase
I Improvements are Substantially Complete or (ii) Lessee occupies Phase I and
commences to conduct business operations or (iii) if Lessor is prevented from
or delayed in completing its work under Section 2 of this Lease due to Lessee
Delays, such work will be deemed Substantially Complete as of the date on which
it would have been Substantially Complete had it not been for such Lessee
Delays.  It is the intention of Lessee and Lessor that March 1, 1997 shall be
the Commencement Date.

"Substantially Complete" shall mean that: (i) Lessor has tendered possession of
Phase I to Lessee, (ii) Lessor has met all legal requirements for occupancy of
Phase I, (iii) the Lessee Interior Improvements for Phase I are materially
complete per the approved plans, exclusive of telephone or other communication
systems, punchlist items and there remains no incomplete or defective items of
work which would materially adversely affect Lessee's intended use of the
Premises and (iv) said interior of the building is in a "broom clean"
condition.

2. IMPROVEMENTS


Page 3



  A. PHASE I IMPROVEMENTS:  The "Phase I Improvements" shall be defined as all
  items necessary for a turnkey remodel of Phase I.  The Phase I Improvements
  shall be constructed by independent contractors to be employed by and under
  the supervision of Lessor in accordance with complete plans and
  specifications prepared by Lessor for submission to the City of Cupertino
  ("Phase I Improvement Plans"), complete with all mechanical and electrical
  design, approved by Lessee, and then attached hereto as Exhibit B.1.  Lessee
  and its designated representatives, shall at all times during the
  construction of the Phase I Improvements have access to the building to
  monitor the progress of construction and Lessor's compliance with its
  obligations hereunder, provided however, that such access shall not
  unreasonably interfere with the activities of Lessor or its contractors.  If
  Lessor notifies Lessee that any fittings, finishes, or other materials
  included in the specifications for the Phase I Improvements cannot be
  obtained within fifteen (15) days after an order therefor, Lessee shall be
  responsible for selecting alternative fittings, finishes, or other materials
  which can be obtained within said fifteen (15) day period including Rent for
  each day of delay.

  Lessor shall be responsible for ensuring that the Phase I Improvements
  conform to the approved plans and all applicable statutes, rules,
  regulations, ordinances, and City of Cupertino Building Department.

  Lessor estimates the total cost of the turnkey Phase I Improvements will be
  one million one hundred fifty thousand dollars ($1,150,000) including all
  items shown on Exhibit B.
  
  Lessor shall be responsible for and shall pay the cost of the Phase I
  Improvements up to the amount of Two Hundred Thousand Dollars ($200,000) (the
  "Phase I TI Allowance").  Lessee's cash budget for the Phase I Improvements
  shall be Nine Hundred Fifty Thousand Dollars ($950,000) ("Lessee's Phase I
  Costs").  Costs in excess of the Phase I TI Allowance and Lessee's Phase I
  Costs shall not be incurred without the advance approval of Lessee.  Any
  approved cost over the Phase I TI Allowance shall be paid for by Lessee in
  cash within fifteen (15) days after Lessor has provided Lessee with evidence
  that the billed work is complete.  Lessor shall be entitled to a construction
  management fee covering its overhead and profit on the Phase I TI Allowance
  and Lessee's Phase I Costs of six percent (6%).  All costs for the Phase I
  Improvements shall be documented and subject to verification by Lessee.

  For any contract to be entered into between Lessor and any contractor
  furnishing labor or materials in connection with the construction of the
  Lessee Interior Improvements where the payment due under such contract is
  estimated by Lessor to be in excess of One Hundred Thousand Dollars $100,000,
  Lessor shall request bids from at least three (3) qualified contractors
  selected by Lessor for bidding.  Lessor will accept the lowest qualified bid.
  Lessee shall have the opportunity to review the qualified bidders list and
  may select a bidder of their choice for any bid provided the bidder meets
  Lessor's reasonable requirements.  Within five (5) business days after
  approval by Lessee of Lessor's single line drawings depicting the Phase I
  Improvements, together with specifications for HVAC and electrical
  installations which will be included in the Phase I Improvements, Lessor
  shall provide Lessee with a guaranteed maximum price for the construction of
  the Phase I Improvements.  Following approval of that amount by Lessee,
  Lessee shall have no obligation to pay any costs in excess of the guaranteed
  maximum price in connection with the construction of the Phase I
  Improvements, except to the extent that the cost of such construction is
  increased by changes approved by Lessee.

  Lessor shall use its best efforts to cause the Commencement Date of the
  initial term to occur not later than March 1, 1997.  If the Commencement Date
  has not occurred by April 1, 1997, Lessee shall receive one day of base rent
  abatement for each day after April 1, 1997 until the Commencement Date.
  Lessor and Lessee agree that having a Commencement Date after April 1, 1997
  will cause Lessee and Lessor to incur costs not contemplated by this Lease,
  the exact amount of which will be extremely difficult to ascertain.
  Accordingly, the parties hereby agree that Lessee's right to the amount of
  one day's rent for each day of delay after April 1, 1997 represents a fair
  and reasonable settlement for both parties and neither party shall


Page 4



  have further liability to the other for any damages.  If the Commencement 
  Date has not occurred by April 30, 1997, Lessee may at its sole option, by 
  written notice to Lessor, have the right to terminate this Lease at any time 
  after April 30, 1997 until the Commencement Date.  Notwithstanding anything 
  to the contrary herein, all dates stated herein shall be extended for the 
  number of days  Lessor is unable to Substantially Complete the Building as a 
  result of delays (i) due to governmental actions (other than governmental 
  action of refusing to approve work which fails to comply with the law or the 
  building permit) which occurs after receipt of normal building permits, (ii) 
  due to acts of God, , and (iii) due to Lessee Delays.  Items (i) and (ii) are 
  referred to herein as Third Party Delays ("Third Party Delays").  "Lessee 
  Delays" means a delay in Substantial Completion resulting from (a) Lessee's 
  failure to meet Lessee's deadlines for approval as shown on Exhibit E, (b) 
  delays due to change orders, (c) delays due to Lessee's failure to meet the 
  deadlines for approving any plans or change orders, and (d) delays because of 
  the inability to obtain any product, materials, design, color, fitting, or 
  finish pursuant to this Section 2.  Lessee shall have a maximum of 3 business 
  days to approve or disapprove any preliminary plans or change orders and a 
  maximum of 10 business days to approve or disapprove any final plans.  If 
  Lessee does not disapprove any plans or change orders within the time period 
  set forth herein in writing, Lessor may proceed on the basis that the plans 
  or change orders are approved by Lessee.  If plans or change orders are 
  disapproved, Lessee shall state the reason for disapproval and Lessor and 
  Lessee shall act in good faith to resolve any issues.  Lessor shall charge 
  Lessee $250 per change order after the fifth (5th) change order for 
  processing. 
  
  Notwithstanding any other provisions herein, Lessee shall during the Lease 
  Term own all Phase I Improvements paid for by Lessee.  Ownership of these 
  improvements shall, for the sum of $1.00, the receipt of which is hereby 
  acknowledged, revert to Lessor at the end of the Lease Term or earlier 
  expiration of this Lease. 

  B. PHASE II BUILDING SHELL AND LESSEE'S INTERIOR IMPROVEMENTS: The "Building 
  Shell", as defined on the attached Exhibit C shall be constructed at Lessor's 
  sole cost and expense. 

  The "Phase II Lessee Interior Improvements" shall be defined as all items
  that are not part of the Building Shell and shall be constructed by
  independent contractors to be employed by and under the supervision of Lessor
  in accordance with complete plans and specifications prepared by Lessor for
  submission to the City of Cupertino ("Phase II Lessee Improvement Plans"),
  complete with all mechanical and electrical design, approved by Lessee, and
  then to be attached hereto as Exhibit D.  Lessee and its designated
  representatives, shall at all times during the construction of  the Phase II
  Lessee Interior Improvements have access to the building to monitor the
  progress of construction and Lessor's compliance with its obligation
  hereunder; provided however, that such access shall not unreasonably
  interfere with the activities of Lessor or its contractors.  If Lessor
  notifies Lessee that any fittings, finishes or other materials included in
  the specifications for the Lessee Interior Improvements cannot be obtained
  within fifteen (15) days after placing an order therefor, Lessee shall be
  responsible for selecting alternative fittings, finishes, or other materials
  which can be obtained within said fifteen (15) day period, or, if Lessee does
  not specify any alternative, Lessee shall be responsible for any delay beyond
  said fifteen (15) day period including Rent for each day of delay.

  Lessor shall be responsible for ensuring that the Phase II Lessee Interior
  Improvements conform to the approved plans and all applicable statutes,
  rules, regulations, ordinances, and City of Cupertino Building Department.

  For any contract to be entered into between Lessor and any contractor
  furnishing labor or materials in connection with the construction of the
  Lessee Interior Improvements where the payment due under such contract is
  estimated by Lessor to be in excess of One Hundred Thousand Dollars $100,000,
  Lessor shall request bids from at least three (3) qualified contractors
  selected by Lessor for bidding.  Lessor will accept the lowest qualified bid.
  Lessee shall have the opportunity to review the qualified bidders list and
  may select a bidder of their choice for any bid provided the bidder meets
  Lessor's


Page 5



  reasonable requirements.  Within five (5) business days after approval by 
  Lessee of  Lessor's single line drawings depicting the Phase II Lessee 
  Interior Improvements, together with specifications for HVAC and electrical 
  installations which will be included in the Phase II Lessee Interior 
  Improvements, Lessor shall provide Lessee with a guaranteed maximum price 
  for the construction of the Phase II Lessee Interior Improvements.
  Following approval of that amount by Lessee, Lessee shall have no obligation
  to pay any costs in excess of the guaranteed maximum price in connection with
  the construction of the Phase II Lessee Interior Improvements, except to the
  extent that the cost of such construction is increased by changes approved by
  Lessee.

  Lessor shall be responsible for and shall pay the cost of the Phase II Lessee
  Interior Improvements up to the amount of Five Hundred Thousand Dollars
  ($500,000)  (the "Phase II TI Allowance").  In the event the approved cost of
  the Phase II Lessee Interior Improvements is more than the Phase II TI
  Allowance Lessee shall pay the excess cost in cash, as provided for herein.
  Costs in excess of the Phase II TI Allowance, if any,  will not be incurred
  without advance approval of Lessee.  Any approved cost over the Phase II TI
  Allowance shall be paid  in cash within fifteen (15) days after Lessor has
  provided Lessee with any invoice for the portion of the work that has been
  completed.  Lessor shall be entitled to a construction management fee
  covering its overhead and profit on the costs of the Phase II Lessee Interior
  Improvements  of six percent (6%).  All costs for Phase II Lessee Interior
  Improvements shall be documented and subject to verification by Lessee.

  Lessor shall use its best efforts to cause the Substantial Completion of
  Phase II  to occur not later than September 1, 1998.  All base rent related
  to Phase II shall be adjusted for each day the Phase II Lessee Interior
  Improvements are not Substantially Complete after September 1, 1998.  Lessor
  and Lessee agree that having a Substantial Completion date for Phase II after
  September 1, 1998 will cause Lessee and Lessor to incur costs not
  contemplated by this Lease, the exact amount of which will be extremely
  difficult to ascertain.  Accordingly, the parties hereby agree that Lessee's
  right to the abatement of base rent specified herein  represents a fair and
  reasonable settlement for both parties and neither party shall have further
  liability to the other for any damages.  If the Phase II Lessee Interior
  Improvements are not Substantially Complete by October 1, 1998, Lessee may at
  its sole option, by written notice to Lessor, have the right to terminate
  this Lease for applicable to the Phase II space at any time after October 1,
  1998 until the Commencement Date.  Notwithstanding anything to the contrary
  herein, all dates stated herein shall be extended for the number of days
  Lessor is unable to Substantially Complete the Building as a result of delays
  (i) due to governmental actions (other than governmental action of refusing
  to approve work which fails to comply with the law or the building permit)
  which occurs after receipt of normal building permits, (ii) due to acts of
  God, , and (iii) due to Lessee Delays.  Items (i) and (ii) are referred to
  herein as Third Party Delays ("Third Party Delays").  "Lessee Delays" means a
  delay in Substantial Completion resulting from (a) Lessee's failure to meet
  Lessee's deadlines for approval as shown on Exhibit E, (b) delays due to
  change orders, (c) delays due to Lessee's failure to meet the deadlines for
  approving any plans or change orders, and (d) delays because of the inability
  to obtain any product, materials, design, color, fitting, or finish pursuant
  to this Section 2.  Lessee shall have a maximum of 3 business days to approve
  or disapprove any preliminary plans or change orders and a maximum of 10
  business days to approve or disapprove any final plans.  If Lessee does not
  disapprove any plans or change orders within the time period set forth herein
  in writing, Lessor may proceed on the basis that the plans or change orders
  are approved by Lessee.  If plans or change orders are disapproved, Lessee
  shall state the reason for disapproval and Lessor and Lessee shall act in
  good faith to resolve any issues.  Lessor shall charge Lessee $250 per change
  order after the fifth (5th) change order for processing.

  Lessor further agrees, at its cost, to spend up to Fifty Thousand Dollars
  ($50,000) to upgrade the exterior of Phase I as part of the Phase II Lessee
  Interior Improvements.


Page 6




  Notwithstanding the above obligations with respect to the Building Shell and
  the Phase II Lessee Interior Improvements, Lessor's obligation to proceed
  with the indicated improvements shall be subject to Lessee having available
  cash of a minimum of  Ten Million Dollars ($10,000,000) as of the start of
  the Phase II construction.

2.1 ACCEPTANCE OF PREMISES AND COVENANTS TO SURRENDER: Lessor represents that 
the Premises shall be in good order and repair, and shall comply with all 
requirements for occupancy as of the Commencement Date.  Lessee agrees on the 
last day of the Lease Term, or on the sooner termination of this Lease, to 
surrender the Building to Lessor in Good Condition and Repair.  Good 
Condition and Repair ("Good Condition and Repair") shall not mean original 
condition, but shall mean that the Building are in a commercially acceptable 
condition suitable for occupancy by a reasonable lessee.  The interior walls 
of all office and warehouse areas, the floors of all office and warehouse 
areas, all suspended ceilings and any carpeting are to be cleaned and in Good 
Condition and Repair  Lessee also agrees to surrender unto Lessor all 
alterations, additions, and improvements which may have been made in, to, or 
on the Building by Lessee.  Lessor agrees to allow any reasonable alterations 
and improvements and will notify Lessee at the time of approval if such 
improvements or alterations are to be removed at the end of the Lease Term  
or earlier termination of this Lease and the Building restored to its 
condition as of the Commencement Date of the Lease.  Lessee, on or before the 
end of the Lease Term or sooner termination of this Lease, shall remove all 
its personal property and trade fixtures from the Building, and all such 
property not so removed shall be deemed to be abandoned by Lessee.  Lessee 
shall reimburse Lessor for all disposition costs incurred by Lessor relative 
to Lessee's abandoned property. If the Building are not surrendered at the 
end of the Lease Term or earlier termination of this Lease, Lessee shall 
indemnify Lessor against loss or liability resulting from any delay caused by 
Lessee in surrendering the Building including, without limitation, any claims 
made by any succeeding Lessee founded on such delay.

3. USES PROHIBITED: Lessee shall not commit, or suffer to be committed, any 
waste upon the Premises, or any nuisance, or other act or thing which may 
disturb the quiet enjoyment of any other tenant in or around the buildings in 
which the subject Premises are located or allow any sale by auction upon the 
Premises, or allow the Premises to be used for any improper, immoral, 
unlawful or objectionable purpose, or place any loads upon the floor, walls, 
or ceiling which may endanger the structure, or use any machinery or 
apparatus which will in any manner vibrate or shake the Building, or place 
any harmful liquids in the drainage system of the building.  No waste 
materials or refuse shall be dumped upon or permitted to remain upon any part 
of the Premises outside of the building proper.  No materials, supplies, 
equipment, finished products or semi-finished products, raw materials or 
articles of any nature shall be stored upon or permitted to remain on any 
portion of the Premises outside of the building structure, unless approved by 
the local, state federal or other applicable governing authority.  Lessor 
consents to Lessee's use of materials which are incidental to the normal, 
day-to-day operations of any office user, such as copier fluids, cleaning 
materials, etc., but this does not relieve Lessee of any of its obligations 
not to contaminate the Premises or related real property or violated any 
Hazardous Materials Laws.

4. ALTERATIONS AND ADDITIONS: Lessee shall not make, or suffer to be made, 
any alteration or addition to the Building, or any part thereof, without the 
express, advance written consent of Lessor; any addition or alteration to 
said Building, except movable furniture and trade fixtures, shall become at 
once a part of the realty and belong to Lessor at the end of the Lease Term 
or earlier termination of this Lease.  Alterations and additions which are 
not deemed as trade fixtures shall include HVAC systems, lighting systems, 
electrical systems, partitioning, carpeting, or any other installation which 
has become an integral part of the Building.  Lessee agrees that it will not 
proceed to make such alterations or additions until all required government 
permits have been obtained and after having obtained consent from Lessor to 
do so, until five (5) days from the receipt of such consent, so that Lessor 
may post appropriate notices to avoid any liability to contractors or 
material suppliers for payment for Lessee's improvements.  Lessee shall at 
all times permit such notices to be posted and to remain posted until the 
completion of work.  At the end of the Lease Term or earlier termination of 
this Lease, Lessee shall remove and shall be required to remove its special 
tenant improvements and all related equipment installed by Lessee at or 
during the Lease Term and Lessee shall 

Page 7


return the Building to the condition that existed before the installation of 
the special tenant improvements.  Notwithstanding the above, Lessor agrees to 
allow any reasonable alterations and improvements and will notify Lessee at 
the time of approval if such improvements or alterations are to be removed at 
the end of the Lease Term or earlier termination of this Lease.

5. MAINTENANCE OF PREMISES:
  (a) Lessee shall at its sole cost and expense keep and maintain the 
  interior of the Building, including, but not limited to, all lighting 
  systems, temperature control systems, all window washing, exterior and 
  interior, clean room systems other than base HVAC units and plumbing 
  systems, in Good Condition and Repair, including any required replacements. 
   Lessee shall maintain all wall surfaces and floor coverings in Good 
  Condition and Repair, free of holes, gouges, or defacements.

  (b) Lessor shall keep and maintain in Good Condition and Repair including 
  replacements, at Lessee's expense, based on a pro-rata share of cost based 
  on square footage or costs directly related to Lessee's use of the Premises 
  the following, which shall be included in the monthly CAC:
     1. The exterior of the building, any appurtenances and every part
     thereof, including but not limited to, glazing, sidewalks, parking
     areas, electrical systems, HVAC systems,  roof membrane, and painting
     of exterior walls.
     2. The HVAC by a service contract with a licensed air conditioning
     and heating contractor which contract shall provide for a minimum of
     quarterly maintenance of all air conditioning and heating equipment
     at the Building including HVAC repairs or replacements which are
     either excluded from such service contract or any existing equipment
     warranties.
     3. The landscaping by a landscape contractor to water, maintain, trim
     and replace, when necessary, any shrubbery and landscaping at the
     Premises.
     4. The roof membrane by a service contract with a licensed reputable
     roofing contractor which contract shall provide for a minimum of semi-
     annual maintenance, cleaning of storm gutters, drains, removing of
     debris and trimming overhanging trees, repair of the roof and
     application of a finish coat every five years at the Building.
     5. Extermination services.
     6. Fire monitoring services.
     
  (c) Lessee hereby waives any and all rights to make repairs at the expense 
  of Lessor as provided in Section 1942 of the Civil Code of the State of 
  California, and all rights provided for by Section 1941 of said Civil Code. 
  Lessor shall assign any warranties, guaranties and similar rights which 
  would apply to the Building elements to be maintained by Lessee and shall 
  cooperate with Lessee as reasonably necessary to enforce such rights.
  
  (d) Lessor shall be responsible and pay for the repair of any structural 
  defects in the Building including the roof structure (not membrane, except 
  as provided at Lessee's expense in 5(b) above), exterior walls and 
  foundation and to correct any condition which does not comply with 
  applicable laws after completion of the Phase I or Phase II Improvements.

6. HAZARD INSURANCE: Lessee shall not use, or permit said Premises, or any 
part thereof, to be used, for any purpose other than that for which said 
Premises are hereby leased; and no use shall be made or permitted to be made 
of the Premises, nor acts done, which may cause a cancellation of any 
insurance policy covering said building, or any part thereof, nor shall 
Lessee sell or permit to be kept, used or sold, in or about said Premises, 
any article which may be prohibited by a standard form fire insurance policy. 
Lessee shall, at its sole cost 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 general 
liability insurance, 

Page 8


covering said building and appurtenances.  Lessor agrees to purchase and keep 
in force fire and extended coverage insurance covering loss or damage to the  
Premises in amounts equal  to the full replacement cost of the Premises as 
determined by Lessor, with proceeds payable to Lessor.  Lessee acknowledges 
that the insurance referenced above does not include coverage for Lessee's 
personal property.  In the event of a loss per the insurance provisions of 
this paragraph, Lessee shall be responsible for deductibles up to a maximum 
of $5,000 per occurrence.  Lessee agrees to pay to the Lessor as additional 
Rent, on demand, the full cost of said insurance as evidenced by insurance 
billings to the Lessor which shall be included in Lessee's monthly CAC.    If 
said insurance billings cover the Premises, and Lessee does not occupy the 
entire Premises, the insurance premiums and deductibles shall be allocated to 
the portion of the Premises occupied by Lessee on a  pro-rata square footage 
or other equitable basis, as determined by Lessor.  It is understood and 
agreed that Lessee's obligation under this paragraph will be prorated to 
reflect the Commencement Date and the end of the Lease Term.

Lessor and Lessee hereby waive any rights each may have against the other 
related to any loss or damage caused to Lessor or Lessee as the case may be, 
or to the Premises, the Building,  or its contents, and which may arise from 
any risk generally covered by fire and extended coverage insurance.  The 
parties shall provide that their respective insurance policies insuring the 
property or the personal property include a waiver of any right of 
subrogation which said insurance company may have against Lessor or Lessee, 
as the case may be. Lessor shall maintain in full force and effect, a policy 
of rental loss insurance, in an amount equal to the amount of Rent payable by 
Lessee commencing on the date of loss during the next ensuing one (1) year, 
as reasonably determined by Lessor with proceeds payable to Lessor ("Loss of 
Rents Insurance").  Lessee shall reimburse Lessor for Lessee's pro-rata share 
of the cost of said rental loss insurance coverage.

7. ABANDONMENT: Lessee shall not vacate or abandon the Building at any time 
during the Lease Term; and if Lessee shall abandon, vacate or surrender the 
Building, or be dispossessed by process of law, or otherwise, any personal 
property belonging to Lessee and left on the Building shall be deemed to be 
abandoned, at the option of Lessor.  Notwithstanding the above, the Building 
shall not be considered vacated or abandoned if Lessee maintains the Building 
in Good Condition and Repair, provides security and is not in default.

8. FREE FROM LIENS: Lessee shall keep the subject Premises and the property 
in which the subject Premises are situated, free from any and all liens 
including but not limited to liens arising out of any work performed, 
materials furnished, or obligations incurred by Lessee.  However, the Lessor 
shall allow Lessee to contest a lien claim, so long as the claim is 
discharged prior to any foreclosure proceeding being initiated against the 
property and provided Lessee provides Lessor a bond if the lien exceeds 
$5,000.

9. COMPLIANCE WITH GOVERNMENTAL REGULATIONS: Lessee shall, at its sole cost 
and expense, comply with all of the requirements of all local, municipal, 
state and federal authorities after the Commencement Date, or which may 
hereafter be in force, pertaining to Lessee's use and occupancy of the said 
Premises, and shall faithfully observe in the use of the Premises all local 
and municipal ordinances and state and federal statutes in force after the 
Commencement Date or which may hereafter be in force.  Except as stated 
above, Lessee shall not be required to pay for the construction of any single 
improvement resulting from future government regulation under this paragraph 
in excess of $5,000, unless such improvement is required to comply with 
Lessee's particular use of the Premises; if such improvement is not required 
due to Lessee's particular use of the Premises and such improvement cost 
exceeds $5,000, such improvement cost shall be amortized over ten (10) years 
at Wells Fargo prime rate plus one percent (1%).  Lessee shall pay to Lessor 
the amortized costs of such improvement on a monthly basis over the Lease 
Term.

10. LESSEE'S INSURANCE: Lessee, as a material part of the consideration to be 
rendered to Lessor, hereby waives all claims against Lessor and Lessor's 
Agents for damages to goods, wares and merchandise, and all other personal 
property in, upon or 

Page 9


about said Premises, and for injuries to persons in, upon or about said 
Premises, from any cause arising at any time, and Lessee will hold Lessor and 
Lessor's Agents exempt and harmless from any damage or injury to any person, 
or to the goods, wares and merchandise and all other personal property of any 
person, arising from the use or occupancy of the Premises by Lessee, or from 
the failure of Lessee to keep the Building in good condition and repair, as 
herein provided.  Lessee shall secure and keep in force a standard policy of 
commercial general liability insurance and property damage policy covering 
the Premises, including parking areas, insuring the Lessee.   A certificate 
of said policy naming Lessor as an additional insured shall be delivered to 
Lessor and will have a combined single limit for both bodily injury, death 
and property damage in an amount not less than five million dollars 
($5,000,000.00).  The limits of said insurance shall not, however, limit the 
liability of Lessee hereunder.  Lessee shall obtain a written obligation on 
the part of the insurer to notify Lessor 30 days in advance in writing before 
any cancellation thereof. Lessee shall obtain, at Lessee's sole cost and 
expense, a policy of fire and extended coverage insurance including coverage 
for direct physical loss special form, and a sprinkler leakage endorsement 
insuring the personal property of Lessee.  The proceeds from any personal 
property damage policy shall be payable to Lessee.  Lessee shall, at its sole 
cost and expense, comply with all of the insurance requirements of all local, 
municipal, state and federal authorities now in force, or which may hereafter 
be in force, pertaining to Lessee's use and occupancy of the said Premises.

11. ADVERTISEMENTS AND SIGNS: Lessee shall not place or permit to be placed, 
in, upon or about the Premises any unusual or extraordinary signs, or any 
signs not approved by the city, local, state, federal or other applicable 
governing authority. Lessee shall not place, or permit to be placed upon the 
Premises, any signs, advertisements or notices without the written consent of 
the Lessor, and such consent shall not be unreasonably withheld.  A sign so 
placed on the Premises shall be so placed upon the understanding and 
agreement that Lessee will remove same at the end of the Lease Term or 
earlier termination of this Lease and repair any damage or injury to the 
Premises caused thereby, and if not so removed by Lessee, then Lessor may 
have the same removed at Lessee's expense.  Lessor hereby consents to the 
placement of a monument sign identifying Lessee, subject to Lessor's 
reasonable approval as to the placement and appearance of the signage, and 
further subject to compliance with the requirements of applicable government 
agencies.

12. UTILITIES: Lessee shall pay for all water, gas, heat, light, power, 
telephone and other utilities supplied to the Building.  Any charges for 
sewer usage or related fees shall be the obligation of Lessee and paid for by 
Lessee. If any such services are not separately metered to Lessee, Lessee 
shall pay a reasonable proportion of all charges which are jointly metered, 
the determination to be made by Lessor acting reasonably and on any equitable 
basis.  Lessor shall not be liable to Lessee for any disruption in any of the 
utility services to the Building or Premises.

13. ATTORNEY'S FEES: In case suit should be brought for the possession of the 
Building or Premises, for the recovery of any sum due hereunder, or because 
of the breach of any other covenant herein, the losing party shall pay to the 
prevailing party reasonable attorney's fee which shall be deemed to have 
accrued on the commencement of such action and shall be enforceable whether 
or not such action is prosecuted to judgment.

14.1 DEFAULT: The occurrence of any of the following shall constitute a 
default and breach of this Lease by Lessee: a) Any failure by Lessee to pay 
Rent or to make any other payment required to be made by Lessee hereunder 
when due if not cured within ten (10) days after written notice thereof by 
Lessor to Lessee; b) The abandonment or vacation of the Premises by Lessee 
except as provided in Section 7; c) A failure by Lessee to observe and 
perform any other provision of this Lease to be observed or performed by 
Lessee, where such failure continues for thirty days after written notice 
thereof by Lessor to Lessee; provided, however, that if the nature of such 
default is such that the same cannot be reasonably cured within such thirty 
(30) day period, Lessee shall not be deemed to be in default if Lessee shall, 
within such period, commence such cure and thereafter diligently prosecute 
the same to completion; d) The making by Lessee of any general assignment for 
the benefit of creditors; the filing by or against Lessee of a petition to 
have Lessee adjudged a bankrupt or of a petition for reorganization or 
arrangement under any 

Page 10


law relating to bankruptcy; e) the appointment of a trustee or receiver to 
take possession of substantially all of Lessee's assets or Lessee's interest 
in this Lease, or the attachment, execution or other judicial seizure of 
substantially all of Lessee's assets located at the Premises or of Lessee's 
interest in this Lease.

14.2 SURRENDER OF LEASE: In the event of any such default by Lessee, then in 
addition to any other remedies available to Lessor at law or in equity, 
Lessor shall have the immediate option to terminate this Lease before the end 
of the Lease Term and all rights of Lessee hereunder, by giving written 
notice of such intention to terminate.  In the event that Lessor terminates 
this Lease due to a default of Lessee, then Lessor may recover from Lessee: 
a) the worth at the time of award of any unpaid Rent which had been earned at 
the time of such termination; plus b) the worth at the time of award of 
unpaid Rent which would have been earned after termination until the time of 
award exceeding the amount of such rental loss that the Lessee proves could 
have been reasonably avoided; plus c) the worth at the time of award of the 
amount by which the unpaid Rent for the balance of the Lease Term after the 
time of award exceeds the amount of such rental loss that the Lessee proves 
could have been reasonably avoided; plus d) any other amount necessary to 
compensate Lessor for all the detriment proximately caused by Lessee's 
failure to perform his obligations under this Lease or which in the ordinary 
course of things would be likely to result therefrom; and e) at Lessor's 
election, such other amounts in addition to or in lieu of the foregoing as 
may be permitted from time to time by applicable California law.  As used in 
(a) and (b) above, the "worth at the time of award" is computed by allowing 
interest at the rate of Wells Fargo's prime rate plus two percent (2%) per 
annum.  As used in (c) above, the "worth at the time of award" is computed by 
discounting such amount at the discount rate of the Federal Reserve Bank of 
San Francisco at the time of award plus one percent (1%).

14.3 RIGHT OF ENTRY AND REMOVAL: In the event of any such default by Lessee, 
Lessor shall also have the right, with or without terminating this Lease, to 
re-enter the Building and remove all persons and property from the Building; 
such property may be removed and stored in a public warehouse or elsewhere at 
the cost of and for the account of Lessee.

14.4 ABANDONMENT: In the event of the vacation or abandonment, except as 
provided in Section 7, of the Building by Lessee or in the event that Lessor 
shall elect to re-enter as provided in paragraph 14.3 above or shall take 
possession of the Premises pursuant to legal proceeding or pursuant to any 
notice provided by law, and Lessor does not elect to terminate this Lease as 
provided in paragraph 14.2 above, then Lessor may from time to time, without 
terminating this Lease, either recover all Rent as it becomes due or relet 
the Building or any part thereof for such term or terms and at such rental 
rates and upon such other terms and conditions as Lessor, in its sole 
discretion, may deem advisable with the right to make alterations and repairs 
to the Building. In the event that Lessor elects to relet the Building, then 
Rent received by Lessor from such reletting shall be applied; first, to the 
payment of any indebtedness other than Rent due hereunder from Lessee to 
Lessor; second, to the payment of any cost of such reletting; third, to the 
payment of the cost of any alterations and repairs to the Building; fourth, 
to the payment of Rent due and unpaid hereunder; and the residue, if any, 
shall be held by Lessor and applied to the payment of future Rent as the same 
may become due and payable hereunder.  Should that portion of such Rent 
received from such reletting during any month, which is applied by the 
payment of Rent hereunder according to the application procedure outlined 
above, be less than the Rent payable during that month by Lessee hereunder, 
then Lessee shall pay such deficiency to Lessor immediately upon demand 
therefor by Lessor.  Such deficiency shall be calculated and paid monthly.  
Lessee shall also pay to Lessor, as soon as ascertained, any costs and 
expenses incurred by Lessor in such reletting or in making such alterations 
and repairs not covered by the rentals received from such reletting.

14.5 NO IMPLIED TERMINATION: No re-entry or taking possession of the Building 
by Lessor pursuant to 14.3 or 14.4 of this Article 14 shall be construed as 
an election to terminate this Lease unless a written notice of such intention 
is given to Lessee or unless the termination thereof is decreed by a court of 
competent jurisdiction.  Notwithstanding any reletting without 

Page 11


termination by Lessor because of any default by Lessee, Lessor may at any 
time after such reletting elect to terminate this Lease for any such default.

15. SURRENDER OF LEASE: The voluntary or other surrender of this Lease by 
Lessee, or a mutual cancellation thereof, shall not work a merger, and shall, 
at the option of Lessor, terminate all or any existing subleases or sub 
tenancies, or may, at the option of Lessor, operate as an assignment to him 
of any or all such subleases or sub tenancies.

16. TAXES: Lessee shall pay and discharge punctually and when the same shall 
become due and payable without penalty, all real estate taxes, personal 
property taxes, taxes based on vehicles utilizing parking areas in the 
Premises, taxes computed or based on rental income (other than federal, state 
and municipal net income taxes), Environmental Surcharges, privilege taxes, 
excise taxes, business and occupation taxes, school fees or surcharges, gross 
receipts taxes, sales and/or use taxes, employee taxes, occupational license 
taxes, water and sewer taxes, assessments (including, but not limited to, 
assessments for public improvements or benefit), assessments for local 
improvement and maintenance districts, and all other governmental impositions 
and charges of every kind and nature whatsoever, regardless of whether now 
customary or within the contemplation of the parties hereto and regardless of 
whether resulting from increased rate and/or valuation, or whether 
extraordinary or ordinary, general or special, unforeseen or foreseen, or 
similar or dissimilar to any of the foregoing (all of the foregoing being 
hereinafter collectively called "Tax" or "Taxes") which, at any time during 
the Lease Term, shall be applicable or against the Premises, or shall become 
due and payable and a lien or charge upon the Premises under or by virtue of 
any present or future laws, statutes, ordinances, regulations, or other 
requirements of any governmental authority whatsoever. The term 
"Environmental Surcharge" shall include any and all expenses, taxes, charges 
or penalties imposed by the Federal Department of Energy, Federal 
Environmental Protection Agency, the Federal Clean Air Act, or any 
regulations promulgated thereunder, or any other local, state or federal 
governmental agency or entity now or hereafter vested with the power to 
impose taxes, assessments or other types of surcharges as a means of 
controlling or abating environmental pollution or the use of energy (i) 
generally imposed on similar properties in a wide geographic area without 
regard to whether the properties are subject to the tax are contaminated by 
Hazardous Materials and which is part of a comprehensive plan imposed by a 
governmental unit or (ii) imposed with respect to the Premises as the result 
of presence of Hazardous Materials for which Lessee is required to indemnify 
Lessor under Section 33.The term "Tax" shall include, without limitation, all 
taxes, assessments, levies, fees, impositions or charges levied, imposed, 
assessed, measured, or based in any manner whatsoever (i) in whole or in part 
on the Rent payable by Lessee under this Lease, (ii) upon or with respect to 
the use, possession, occupancy, leasing, operation or management of the 
Premises, (iii) upon this transaction or any document to which Lessee is a 
party creating or transferring an interest or an estate in the Premises, (iv) 
upon Lessee's business operations conducted at the Premises, (v) upon, 
measured by or reasonably attributable to the cost or value of Lessee's 
equipment, furniture, fixtures and other personal property located on the 
Premises or the cost or value of any leasehold improvements made in or to the 
Premises by or for Lessee, regardless of whether title to such improvements 
shall be in Lessor or Lessee, or (vi) in lieu of or equivalent to any Tax set 
forth in this Section 16.  In the event any such Taxes are payable by Lessor 
and it shall not be lawful for Lessee to reimburse Lessor for such Taxes, 
then the Rent payable thereunder shall be increased to net Lessor the same 
net rent after imposition of any such Tax upon Lessor as would have been 
payable to Lessor prior to the imposition of any such Tax.  It is the 
intention of the parties that Lessor shall be free from all such Taxes and 
all other governmental impositions and  charges of every kind and nature 
whatsoever. However, nothing contained in this Section 16 shall require 
Lessee to pay any Federal or State income, franchise, estate, inheritance, 
succession, transfer or excess profits tax imposed upon Lessor.   If any 
general or special assessment is levied and assessed against the Premises, 
Lessor agrees to use its best reasonable efforts to cause the assessment to 
become a lien on the Premises securing repayment of a bond sold to finance 
the improvements to which the assessment relates which is payable in 
installments of principal and interest over the maximum term allowed by law.  
It is understood and agreed that Lessee's obligation under this paragraph 
will be prorated to reflect the Commencement Date and the end of the Lease 
Term.  It is further understood that if Taxes cover the Premises and Lessee 
does not occupy the entire Premises, the Taxes will be 

Page 12


allocated to the portion of the Premises occupied by Lessee based on a 
pro-rata square footage or other equitable basis.  Taxes billed by Lessor to 
Lessee shall be included in the monthly CAC.

Subject to any limitations or restrictions imposed by any deeds of trust or 
mortgages now or hereafter covering or affecting the Premises, Lessee shall 
have the right to contest or review the amount or validity of any Tax by 
appropriate legal proceedings but which is not to be deemed or construed in 
any way as relieving, modifying or extending Lessee's covenant to pay such 
Tax at the time and in the manner as provided in this Section 16.  However, 
as a condition of Lessee's right to contest, if such contested Tax is not 
paid before such contest and if the legal proceedings shall not operate to 
prevent or stay the collection of the Tax so contested, Lessee shall, before 
instituting any such proceeding, protect the Premises and the interest of 
Lessor and of the beneficiary of a deed of trust or the mortgagee of a 
mortgage affecting the Premises against any lien upon the Premises by a 
surety bond, issued by an insurance company acceptable to Lessor and in an 
amount equal to one and one-half (1 1/2) times the amount contested or, at 
Lessor's option, the amount of the contested Tax and the interest and 
penalties in connection therewith.  Any contest as to the validity or amount 
of any Tax, whether before or after payment, shall be made by Lessee in 
Lessee's own name, or if required by law, in the name of Lessor or both 
Lessor and Lessee.  Lessee shall defend, indemnify  and hold harmless Lessor 
from and against any and all costs or expenses, including attorneys' fees, in 
connection with any such proceedings brought by Lessee, whether in its own 
name or not. Lessee shall be entitled to retain any refund of any such 
contested Tax and penalties or interest thereon which have been paid by 
Lessee.  Nothing contained herein shall be construed as affecting or limiting 
Lessor's right to contest any Tax at Lessor's expense.

17. NOTICES: Unless otherwise provided for in this Lease, any and all written 
notices or other communication (the "Communication") to be given in 
connection with this Lease shall be given in writing and shall be given by

prepaid, in a sealed envelope addressed to the intended recipient as follows:

courier, on the first business day following deposit with such overnight 
courier and if given by facsimile transmission, on the day on which it was

business day thereafter.

18. ENTRY BY LESSOR: Lessee shall permit Lessor and its agents to enter into 
the Building at all reasonable times using the minimum amount of interference 
and inconvenience to Lessee and Lessee's business, subject to any security 
regulations of Lessee, for the purpose of inspecting the same or for the 
purpose of maintaining the Building, or for the purpose of making 

Page 13


repairs, alterations or additions to any other portion of said Building, 
including the erection and maintenance of such scaffolding, canopies, fences 
and props as may be required, without any rebate of Rent and without any 
liability to Lessee for any loss of occupation or quiet enjoyment of the 
Premises; and shall permit Lessor and his agents, at any time within ninety 
(90) days prior to the end of the Lease Term, to place upon said Premises any 
usual or ordinary "For Sale" or "For Lease" signs and exhibit the Premises 
and the Building to prospective tenants at reasonable hours.

19. DESTRUCTION OF PREMISES: In the event of a partial destruction of the 
said Premises during the Lease Term from any cause which is covered by 
Lessor's property insurance, Lessor shall forthwith repair the same, provided 
such repairs can be made within ninety (90) days after the issuance of a 
building permit under the laws and regulations of State, Federal, County, or 
Municipal authorities, but such partial destruction shall in no way annul or 
void this Lease, except that Lessee shall be entitled to a proportionate 
reduction of Rent while such repairs are being made to the extent of payments 
received by Lessor under its Loss of Rents Insurance coverage.  With respect 
to any partial destruction which Lessor is obligated to repair or may elect 
to repair under the terms of this paragraph, the provision of Section 1932, 
Subdivision 2, and of Section 1933, Subdivision 4, of the Civil Code of the 
State of California are waived by Lessee.  In the event that the Building is 
destroyed to an extent greater than thirty-three and one-third (33 1/3%) of 
the replacement cost thereof, Lessor may, at its sole option, elect to 
terminate this Lease, whether the subject Premises is insured or not.  A 
total destruction of the Building shall terminate this Lease.  
Notwithstanding the above, Lessor is only obligated to repair or rebuild to 
the extent of any available insurance proceeds including any deductible 
amount.  Should Lessor determine that insufficient or no insurance proceeds 
are available for repair or reconstruction of Premises, Lessor, at its sole 
option, may terminate the Lease.  Lessee shall have the option of continuing 
this Lease by agreeing to pay all repair costs which are not covered by 
insurance available to Lessor. If Lessor reasonably estimates that the repair 
of any damage or destruction to the Premises will require in excess of 120 
days to repair from the date of damage, Lessee shall be entitled to terminate 
this Lease effective upon written notice to Lessor delivered within 15 days 
of receipt of such notice that repairs will exceed 120 days.

20. ASSIGNMENT AND SUBLETTING: Lessee shall not assign this Lease, or any 
interest therein, and shall not sublet the said Building or any part thereof, 
or any right or privilege appurtenant thereto, or cause any other person or 
entity (a bona fide subsidiary or affiliate of Lessee, any entity which 
controls Lessee and any entity which results from the merger, consolidation 
or reorganization of Lessee excepted ("Lessee Affiliate")) to occupy or use 
the Building, or any portion thereof, without the advance written consent of 
Lessor.  Any such assignment or subletting without such consent shall be 
void, and shall, at the option of the Lessor, terminate this Lease.  This 
Lease shall not, or shall any interest therein, be assignable, as to the 
interest of Lessee, by operation of law, without the written consent of 
Lessor. Notwithstanding Lessor's obligation to provide reasonable approval, 
Lessor reserves the right to withhold its consent for any proposed sublessee 
or assignee of Lessee if the proposed sublessee or assignee is a user or 
generator of Hazardous Materials.  If Lessee desires to assign its rights 
under this Lease or to sublet, all or a portion of the subject Building to a 
party other than a Lessee Affiliate, Lessee shall first notify Lessor of the 
proposed terms and conditions of such assignment or subletting.  Lessor and 
Lessee shall split any net proceeds of any sublease other than to a Lessee 
Affiliate 50/50 after deducting amortized leasing costs, the amortization of 
Lessee's TI Allowance, tenant improvements for the subtenant and reasonable 
legal fees in conjunction with securing the subtenant.  Notwithstanding the 
foregoing, Lessee may assign this Lease to a successor in interest, whether 
by merger or acquisition, provided there is no substantial reduction in the 
net worth of the resulting entity and the resulting entity is not a user or 
generator of Hazardous Materials.  Whether or not Lessor's consent to a 
sublease or assignment is required, in the event of any sublease or 
assignment, Lessee shall be and shall remain primarily liable for the 
performance of all conditions, covenants, and obligations of Lessee hereunder 
and, in the event of a default by an assignee or sublessee, Lessor may 
proceed directly against the original Lessee hereunder and/or any other 
predecessor of such assignee or sublessee without the necessity of exhausting 
remedies against said assignee or sublessee.

21. CONDEMNATION: If any part of the Building shall be taken for any public 
or quasi-public use, under any statute or by right of eminent domain or 
private purchase in lieu thereof, and a part thereof remains which is 
susceptible of occupation hereunder, this Lease shall as to the part so 
taken, terminate as of the date title vests in the condemnor or purchaser, 
and the Rent payable hereunder shall be adjusted so that the Lessee shall be 
required to pay for the remainder of the Lease Term only that portion of Rent 
as the value of the part remaining.  The rental adjustment resulting will be 
computed at the same Rental rate for the remaining part not taken; however, 
Lessor shall have the option to terminate this Lease as of the date when 
title to the part so taken vests in the condemnor or purchaser.  If all of 
the Building, or such part thereof be taken so that there does not remain a 
portion susceptible for occupation hereunder, this Lease shall thereupon 
terminate.  If a part or all of the Building be taken, all compensation 
awarded upon such taking shall be payable to the Lessor.  Lessee may file a 
separate claim and be entitled to any award granted to Lessee.

22. EFFECTS OF CONVEYANCE: The term "Lessor" as used in this Lease, means 
only the owner for the time being of the land and building constituting the 
Premises, so that, in the event of any sale of said land or building, or in 
the event of a Lease of said building, Lessor shall be and hereby is entirely 
freed and relieved of all covenants and obligations of Lessor hereunder, and 
it shall be deemed and construed, without further agreement between the 
parties and the purchaser of any such sale, or the Lessor of the building, 
that the purchaser or lessor of the building has assumed and agreed to carry 
out any and all covenants and obligations of the Lessor hereunder.  If any 
security is given by Lessee to secure the faithful performance of all or any 
of the covenants of this Lease on the part of Lessee, Lessor may transfer and 
deliver the security, as such, to the purchaser at any such sale of the 
building, and thereupon the Lessor shall be discharged from any further 
liability.

23. SUBORDINATION: This Lease, in the event Lessor notifies Lessee in 
writing, shall be subordinate to any ground lease, deed of trust, or other 
hypothecation for security now or hereafter placed upon the real property at 
which the Premises are a part and to any and all advances made on the 
security thereof and to renewals, modifications, replacements and extensions 
thereof. Lessee agrees to promptly execute any documents which may be 
required to effectuate such subordination. Notwithstanding such 
subordination, if Lessee is not in default and so long as Lessee shall pay 
the Rent and observe and perform all of the provisions and covenants required 
under this Lease, Lessee's right to quiet possession of the Premises shall 
not be disturbed or effected by any subordination.

24. WAIVER: The waiver by Lessor of any breach of any term, covenant or 
condition, herein contained shall not be construed to be a waiver of such 
term, covenant or condition or any subsequent breach of the same or any other 
term, covenant or condition therein contained.  The subsequent acceptance of 
Rent hereunder by Lessor shall not be deemed to be a waiver of Lessee's 
breach of any term, covenant, or condition of the Lease.

25. HOLDING OVER: Any holding over after the end of the Lease Term requires 
Lessor's written approval prior to the end of the Lease Term, which, 
notwithstanding any other provisions of this Lease, Lessor may withhold and 
shall be construed to be a tenancy at sufferance from month to month.  Lessee 
shall pay to Lessor monthly base rent equal to one and one-quarter (1.25) 
times the monthly base rent installment due in the last month of the Lease 
Term and all other additional rent and all other terms and conditions of the 
Lease shall apply, so far as applicable.  Holding over by Lessee without 
written approval of Lessor shall subject Lessee to the liabilities and 
obligations provided for in this Lease and by law, including, but not limited 
to those in Section 2.1 of this Lease.  Lessee shall indemnify and hold 
Lessor harmless against any loss or liability resulting from any delay caused 
by Lessee in surrendering the Building, including without limitation, any 
claims made or penalties incurred by any succeeding lessee or by Lessor.  No 
holding over shall be deemed or construed to exercise any option to extend or 
renew this Lease in lieu of full and timely exercise of any such option as 
required hereunder.

26. SUCCESSORS AND ASSIGNS: The covenants and conditions herein contained
shall, subject to the provisions as to assignment, apply to and bind the heirs,
successors, executors, administrators and assigns of all of the parties hereto;
and all of the parties hereto shall be jointly and severally liable hereunder.

27. ESTOPPEL CERTIFICATES: Lessee shall at any time during the Lease Term, upon
not less than ten (10) days prior written notice from Lessor, execute and
deliver to Lessor a statement in writing certifying that, this Lease is
unmodified and in full force and effect (or, if modified, stating the nature of
such modification) and the dates to which the Rent and other charges have been
paid in advance, if any, and acknowledging that there are not, to Lessee's
knowledge, any uncured defaults on the part of Lessor hereunder or specifying
such defaults if they are claimed.  Any such statement may be conclusively
relied upon by any prospective purchaser or encumbrancer of the Premises.
Lessee's failure to deliver such a statement within such time shall be
conclusive upon the Lessee that (a) this Lease is in full force and effect,
without modification except as may be represented by Lessor; (b) there are no
uncured defaults in Lessor's performance.

28. TIME: Time is of the essence of the Lease.

29. CAPTIONS: The headings on titles to the paragraphs of this Lease are not a
part of this Lease and shall have no effect upon the construction or
interpretation of any part thereof.  This instrument contains all of the
agreements and conditions made between the parties hereto and may not be
modified orally or in any other manner than by an agreement in writing signed
by all of the parties hereto or their respective successors in interest.

30. PARTY NAMES: Landlord and Tenant may be used in various places in this
Lease as a substitute for Lessor and Lessee respectively.

31. EARTHQUAKE INSURANCE: As a condition of Lessor agreeing to waive the
requirement for earthquake insurance, Lessee agrees that it will pay, as
additional Rent, which shall be included in the monthly CAC, an amount not to
exceed eighteen thousand two hundred dollars ($18,200) per year for earthquake
insurance if Lessor desires to obtain some form of earthquake insurance in the
future, if and when available, on terms acceptable to Lessor.

32. HABITUAL DEFAULT: Notwithstanding anything to the contrary contained in
Section 14 herein, Lessor and Lessee agree that if Lessee shall have defaulted
in the payment of Rent for three or more times during any twelve month period
during the Lease Term, then such conduct shall, at the option of the Lessor,
represent a separate event of default which cannot be cured by Lessee.  Lessee
acknowledges that the purpose of this provision is to prevent repetitive
defaults in the payment of Rent by the Lessee under the Lease, which constitute
a hardship to the Lessor and deprive the Lessor of the timely performance by
the Lessee hereunder.

cost and expense, promptly take any and all action necessary to remediate
contamination of the Premises by Hazardous Materials arising or occurring as a

Lessee shall not be responsible to remediate contamination of the Premises

cost and expense, obtain insurance coverage for "midnight dumping" and similar-
type events if available on terms acceptable to Lessee.

33.6 OBLIGATION TO NOTIFY: Lessor and Lessee shall each give written notice to
the other as soon as reasonably practical of (i) any communication received
from any governmental authority concerning Hazardous Material which related to

33.7 SURVIVAL: The obligations of Lessee under this Section 33 shall survive

33.8 CERTIFICATION AND CLOSURE: On or before the end of the Lease Term or
earlier termination of this Lease, Lessee shall deliver to Lessor a
certification executed by Lessee stating that, to the best of Lessee's

against any claim, cost, liability or cause of action asserted by any broker or
finder claiming through Lessee other than CC.  Lessor shall at its sole cost
and expense pay the brokerage commission per Lessor's standard commission

warrants that it has not utilized or contacted a real estate broker or finder
with respect to this Lease other than CC and Lessor agrees to indemnify and
hold Lessee harmless against any claim, cost, liability or cause of action
asserted by any broker or finder claiming through Lessor.

35. OPTION TO EXTEND
A. OPTION: Lessor hereby grants to Lessee two (2) options to extend the Lease
Term, with each extended term to be for a period of five (5) years, on the
following terms and conditions, which shall apply separately to each option to
extend:


Page 18



     (i) Lessee shall give Lessor written notice of its exercise of one of its
     options to extend no earlier than twenty-four (24) calendar months, nor
     later than six (6) calendar months before the Lease Term would end but for
     said exercise.  Time is of the essence.  Lessee may withdraw from its
     option at any time prior to six (6) months before the end of the Lease
     Term and therefore must give notice in sufficient time to complete all
     lease negotiations and appraisal six (6) months before the end of the
     Lease Term.
     
     (ii) Lessee may not extend the Lease Term pursuant to any option granted
     by this section 35 if Lessee is in default as of the date of the exercise
     of one of its options.  If Lessee has committed a default by Lessee as
     defined in Section 14 or 32 that has not been cured or waived by Lessor in
     writing by the date that any extended term is to commence, then Lessor may
     elect not to allow the Lease Term to be extended, notwithstanding any
     notice given by Lessee of an exercise of this option to extend.
     
     (iii) Lessee must exercise each option consecutively, and if it fails to
     exercise any one option, it waives the right to exercise the subsequent
     option and the Lease Term shall not be extended further.
     
     (iv) All terms and conditions of this Lease shall apply during each
     extended term, except that the Base Rent and rental increases for each
     extended term shall be determined as provided in Section 35 (B) below
     
     (v) Once Lessee delivers a notice of exercise of one of its options to
     extend the Lease Term, Lessee may not withdraw such exercise and subject
     to the provisions of this Section 35, such notice shall operate to extend
     the Lease Term.  Upon any extension of the Lease Term pursuant to this
     Section 35, the term "Lease Term" as used in this Lease shall thereafter
     include the then extended term.
     
     (v) The option rights of General Surgical Innovations Corporation granted
     under this Section 35 may not be assigned or transferred by General
     Surgical Innovations Corporation  other than to an entity which controls,
     is controlled by, or is under common control with Lessee, or which results
     from a merger, consolidation, or reorganization of Lessee, to whom such
     option may be assigned in connection with an assignment of this Lease,
     provided the assignment otherwise complies with the requirements of
     Section 20.

B. EXTENDED TERM RENT - OPTION PERIOD: The monthly Rent for the Building during
the extended term(s) shall equal ninety-five percent (95%) of  the fair market
monthly Rent for the Building as of the commencement date of the extended term,
but in no case (i) less than the Rent during the last month of the prior lease
term and (ii) greater than one hundred five percent (105%) of the Rent during
the last month of the prior lease term.  Promptly upon Lessee's exercise of the
option to extend, Lessee and Lessor shall meet and attempt to agree on the fair
market monthly Rent for the Building as of the commencement date of the
extended term.  In the event the parties fail to agree upon the amount of the
monthly Rent for the extended term prior to commencement thereof, the monthly
Rent for the extended term shall be determined by appraisal in the manner
hereafter set forth; provided, however, that in no event shall the monthly Rent
for the extended term be less than in the immediate preceding period.  Annual
base rent increases during the extended term shall be 3% per year.  In the
event it becomes necessary under this paragraph to determine the fair market
monthly Rent of the Building by appraisal, Lessor and Lessee each shall appoint
a real estate appraiser who shall be a member of the American Institute of Real
Estate Appraiser ("AIREA") and such appraisers shall each determine the fair
market monthly Rent for the Building taking into account the value of the
Premises and the amenities provided by the outside areas, the common areas, and
the Building, and prevailing comparable Rentals in the area.  Such appraisers
shall, within twenty (20) business days after their appointment, complete their
appraisals and submit their appraisal reports to Lessor and Lessee.  If the
fair market monthly Rent of the Building established in the two (2) appraisals
varies by five percent (5%) or less of the higher Rent, the average of the two
shall be controlling.  If said fair market monthly


Page 19



Rent varies by more than five percent (5%) of the higher Rental, said 
appraisers, within ten (10) days after submission of the last appraisal, shall 
appoint a third appraiser who shall be a member of the AIREA and who shall also 
be experienced in the appraisal of Rent values and adjustment practices for 
commercial properties in the vicinity of the Building.  Such third appraiser 
shall, within twenty (20) business days after his appointment, determine by 
appraisal the fair market monthly Rent of the Building taking into account the 
same factors referred to above, and submit his appraisal report to Lessor and 
Lessee.  The fair market monthly Rent determined by the third appraiser for the 
Building shall be controlling, unless it is less than that set forth in the 
lower appraisal previously obtained, in which case the value set forth in said 
lower appraisal shall be controlling, or unless it is greater than that set 
forth in the higher appraisal previously obtained in which case the Rent set 
for in said higher appraisal shall be controlling.  If either Lessor or Lessee 
fails to appoint an appraiser, or if an appraiser appointed by either of them 
fails, after his appointment to submit his appraisal within the required period 
in accordance with the foregoing, the appraisal submitted by the appraiser 
properly appointed and timely submitting his appraisal shall be controlling.  
If the two appraisers appointed by Lessor and Lessee are unable to agree upon a 
third appraiser within the required period in accordance with the foregoing, 
application shall be made within twenty (20) days thereafter by either Lessor 
or Lessee to AIREA, which shall appoint a member of said institute willing to 
serve as appraiser.  The cost of all appraisals under this subparagraph shall 
be borne equally be Lessor and Lessee.

36. APPROVALS: Whenever in this Lease the Lessor's or Lessee's consent is
required, such consent shall not be unreasonably or arbitrarily withheld or
delayed.  In the event that the Lessor or Lessee does not respond to a request
for any consents which may be required of it in this Lease within ten business
days of the request of such consent in writing by the Lessee or Lessor, such
consent shall be deemed to have been given by the Lessor or Lessee.

37. AUTHORITY: Each party executing this Lease represents and warrants that he
or she is duly authorized to execute and deliver the Lease.  If executed on
behalf of a corporation, that the Lease is executed in accordance with the by-
laws of said corporation (or a partnership that the Lease is executed in
accordance with the partnership agreement of such partnership), that no other
party's approval or consent to such execution and delivery is required, and
that the Lease is binding upon said individual, corporation (or partnership) as
the case may be in accordance with its terms.

38. INDEMNIFICATION OF LESSOR: Except to the extent caused by the sole
negligence or willful misconduct of Lessor or Lessor's Agents, Lessee shall
defend, indemnify and hold Lessor harmless from and against any and all
obligations, losses, costs, expenses, claims, demands, attorney's fees,
investigation costs or liabilities on account of, or arising out of the use,
condition or occupancy of the Premises or any act or omission to act of Lessee
or Lessee's Agents or any occurrence in, upon, about or at the Premises,
including, without limitation, any of the foregoing provisions arising out of
the use, generation, manufacture, installation, release, discharge, storage, or
disposal of Hazardous Materials by Lessee or Lessee's Agents.  It is understood
that Lessee is and shall be in control and possession of the Premises and that
Lessor shall in no event be responsible or liable for any injury or damage or
injury to any person whatsoever, happening on, in, about, or in connection with
the Premises, or for any injury or damage to the Premises or any part thereof.
This Lease is entered into on the express condition that Lessor shall not be
liable for, or suffer loss by reason of injury to person or property, from
whatever cause, which in any way may be connected with the use, condition or
occupancy of the Premises or personal property located herein. The provisions
of this Lease permitting Lessor to enter and inspect the Premises are for the
purpose of enabling Lessor to become informed as to whether Lessee is complying
with the terms of this Lease and Lessor shall be under no duty to enter,
inspect or to perform any of Lessee's covenants set forth in this Lease.
Lessee shall further indemnify, defend and hold harmless Lessor from and
against any and all claims arising from any breach or default in the
performance of any obligation to Lessee's part to be performed under the terms
of this Lease.  The provisions of Section 38 shall survive the Lease Term or
earlier termination of this Lease with respect to any damage, injury or death
occurring during the Lease Term.


Page 20



39. LESSOR'S LIABILITY: If Lessee should recover a money judgment against
Lessor arising in connection with this Lease, the judgment shall be satisfied
only out of the Lessor's interest in the Building and neither Lessor or any of
its partners shall be liable personally for any deficiency.

40. INTENTIONALLY OMITTED.

41. LESSEE'S RIGHT OF OFFER: Lessor hereby agrees to telephone and fax notice
to Lessee of any available space owned by Lessor on Bubb Road.  This notice
shall be subordinate to any existing rights of any existing tenants on Bubb
Road.

42. ARBITRATION OF DISPUTES:  If the parties are unable to resolve any dispute
regarding the terms of this Lease or Lessor or Lessee's rights hereunder,
except money to be paid, within 30 days after commencement of good faith
negotiations, any such dispute may be referred to arbitration by either party.
Any unresolved dispute as to any amount or sum of money to be paid by one party
to the other party under the provisions hereof, the party against whom the
obligation to pay the money is asserted shall have the right to make payment
"under protest," such payment not being regarded as voluntary payment and there
shall survive the right on the part of said party to request that the matter be
submitted to arbitration as provided below concerning the recovery of such sum.
Notwithstanding the above, this provision shall not apply to payments of the
base rent or to the initial CAC payable under this Lease or any amount based on
Lessee's pro rata share.  If it shall be adjudged that there was no legal
obligation on the part of said party to pay such sum or any part thereof, said
party shall be entitled to recover such sum or so much thereof as it was not
legally required to pay under the provisions of this Lease.  In the event of
such dispute between Lessor and Lessee regarding the terms of this Lease, or
Lessor and Lessee's rights and obligations hereunder, such dispute shall be
resolved by binding arbitration pursuant to California Code of Civil Procedure
Sections 1280 through 1294.2 or successor stature.  Any such arbitration shall
be held and conducted in San Jose, California.  The prevailing party in such
arbitration shall be entitled to recover its reasonable attorneys' fees and
costs.
