                                  OFFICE LEASE

THIS LEASE, dated May 9, 1999, for purposes of reference only, is made and
entered into by and between 945 BATTERY LLC., a California limited liability
company ("Lessor") and MEDICALOGIC, INC., an Oregon corporation ("Lessee").

                                   WITNESSETH:

Lessor hereby leases to Lessee, and Lessee hereby leases from Lessor, the
premises described in paragraph 1(b) below for the term and subject to the
terms, covenants, agreements and conditions hereinafter set forth, to each and
all of which Lessor and Lessee hereby mutually agree.

1.   Definitions. Unless the context otherwise specifies or requires, the
following terms shall have the meanings herein specified.

     (a) The term "Building" shall mean the building located at 945 Battery
Street, San Francisco, California.

     (b) The term "Premises" shall mean the second floor, third floor,
mezzanine, and penthouse of the Building.

     (c) The term "Lessee's percentage share" shall mean Fifty-Seven and 34/100
percent (57.34%). Lessor and Lessee acknowledge that Lessee's percentage share
has been obtained by dividing the rentable area of the Premises by the total
rentable area of the Building, and multiplying such quotient by 100. In the
event Lessee's percentage share is changed during a calendar year by reason of a
change in the rentable area of the Premises and/or a change in the total
rentable area of the Building, Lessee's percentage share shall thereafter mean
the result obtained by dividing the then rentable area of the Premises by the
then total rentable area of the Building, and multiplying such quotient by 100,
and for the purposes of paragraph 3, Lessee's percentage share shall be
determined on the basis of the number of days during such calendar year at each
such percentage share. The parties hereto agree that the total rentable area of
the Building for purposes of this paragraph (c) is currently 65,540 square feet.

     (d) The term "lease year" shall mean the first 12 full calendar months
during the term hereof together with any partial month at the commencement of
the term, and each successive 12-month period thereafter, provided that the last
lease year of the term may be a partial lease year.

2.   Term. The term of this Lease shall commence on the earlier of the date
Lessor delivers possession of the Premises to Lessee, provided temporary or
permanent certificate of occupancy is issued for the Premises, and Lessor's work
is substantially completed unless sooner terminated as hereinafter provided,
shall continue thereafter for a period of ten (10) years. Notwithstanding the
foregoing, in the event that Lessee selects a general contractor other than
Birmingham Builders, Inc. to perform tenant improvements at the Premises as
provided herein, the term of this Lease shall commence on September 1, 1999
regardless of the date of completion of drawings for tenant improvements to the
Premises, the completion of construction

                                       -1-

of tenant improvements to the Premises, or the date Lessee commences occupancy
of the Premises.

3.   Rental.

     (a) Lessee shall pay to Lessor throughout the term of this Lease as rental
for the Premises the following sums as the Base Rent:

              Years 1-5        $133,096.00 per month

              Years 6-10       $155,017.50 per month

     (b) Rental shall be paid to Lessor on or before the first day of the term
hereof and on or before the first day of each and every successive calendar
month thereafter during the term hereof. In the event the term of this Lease
commences on a day other than the first day of a calendar month or ends on a day
other than the last day of a calendar month, then the monthly rental for the
first and last fractional months of the term hereof shall be appropriately
prorated.

     (c) Lessee hereby acknowledges that late payment by Lessee to Lessor of
rent and other sums due hereunder after the expiration of any applicable grace
period 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 by the terms of any mortgage or trust
deed covering the Premises. Accordingly, if any installment of rent or any other
sums due from Lessee shall not be received by Lessor when due or, if a grace or
cure period is applicable, shall not be received by Lessor prior to the
expiration of the applicable grace or cure period, Lessee shall pay to Lessor a
late charge equal to 6% 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 payment by Lessee. Acceptance of such late charge
by Lessor shall in no event constitute a waiver of Lessee's default with respect
to such overdue amount nor prevent Lessor from exercising any of the other
rights and remedies available to Lessor hereunder or at law.

     (d) Rental and all other payments to be made by Lessee hereunder shall be
paid to Lessor without deduction or offset, in lawful money of the United States
of America at Lessor's address for notices hereunder or to such other person or
at such other place as Lessor may from time to time designate in writing. All
amounts of money payable by Lessee to Lessor hereunder, if not paid within ten
days of the date when due, shall bear interest from the due date until paid at
the highest rate legally permitted.

     (e) All sums of money or charges required to be paid by Lessee hereunder
shall be deemed rental for the Premises and may be designated as such in any
statutory notice to pay rent or quit the Premises.

4.   Letter of Credit as Security. In lieu of making a cash security deposit to
Lessor, Lessee shall, within ten (10) days after execution of this lease,
deliver to Lessor and cause to be in effect during the term hereof an
unconditional, irrevocable letter of credit ("LC") in a form reasonably
acceptable to Lessor. The initial amount of the LC shall be $1,750,000.00.
Provided that Lessee

                                       -2-

is not then in default under this lease, the LC shall remain in place until such
time as Lessee can demonstrate a minimum of $75,000,000 in cash on its month-end
balance sheet, at which point the LC shall be reduced to zero, provided,
however, that if at any time during the term of the Lease, the cash amount on
Lessee's month-end balance sheet falls below $75,000,000, Lessor shall have the
right to require reinstatement of the LC in the full amount of $1,750,000.00. In
the event that the LC is ever reduced to zero pursuant to the preceding
sentence, Lessee shall thereafter provide Lessor with copies of Lessee's
month-end balance sheets on a monthly basis by no later than the fifteenth
(15th) day of each month, or as soon thereafter as such balance sheets have been
prepared for Lessee's internal use.

The LC shall be issued by a bank that accepts deposits, maintains accounts, has
a San Francisco Bay area office that will negotiate a letter of credit, and the
deposits of which are insured by the Federal Deposit Insurance Corporation.
Lessee shall pay all expenses, points, or fees incurred by Lessee in obtaining
the LC. Lessor shall hold the LC as security for the performance of Lessee's
obligations under this lease. If, after notice and failure to cure within any
applicable cure period, Lessee defaults under any provision of this lease,
Lessor may, upon delivery to the issuing bank a statement that Lessee is in
default hereunder beyond the expiration of applicable cure period, without
prejudice to any other remedy it has, draw on that portion of the LC necessary
to pay any rent or other sum in default or to compensate Lessor for any expense,
loss, or damage (including reasonable attorneys' fees) that Lessor may suffer as
a result of Lessee's default. If Lessor draws on any portion of the LC, Lessee
shall, within five (5) business days after written demand by Lessor, either (a)
deposit cash with Lessor in an amount that, when added to the amount remaining
under the LC, shall equal the amount of the LC then required under this
paragraph, or (b) deliver written documentation executed by the bank issuing the
LC confirming that the LC has been reinstated to the amount then required under
this paragraph.

5.   Use. The Premises shall be used for general office purposes and for no
other purpose whatsoever. Any kitchenette facilities installed in the Premises
shall be ancillary to the office use and shall consist of no more than a sink,
dishwasher, refrigerator, microwave, and other UL-rated countertop cooking
equipment such as, for example, only, and not by way of limitation, a toaster
oven or coffeemaker. Lessee shall not do or permit to be done in or about the
Premises, nor bring or keep or permit to be brought or kept therein, anything
which is prohibited by or will in any way conflict with any law, statute,
ordinance or governmental rule or regulation now in force or which may hereafter
be enacted or promulgated, or which is prohibited by the standard form of fire
insurance policy, or will in any way increase the existing rate of or affect any
fire or other insurance upon the Building or any of its contents, or cause a
cancellation of any insurance policy covering the Building or any part thereof
or any of its contents. Lessee shall not use, store, or dispose of in the
Premises any hazardous at toxic substances, with the sole exception of such
substances as are ordinarily used in the course of normal office operations
(such as copier fluids), provided that such substances are kept in only such
quantities as are reasonably required for normal office operations and are used,
handled, stored, and disposed of in accordance with all applicable laws. Losses
shall not do or permit anything to be done in or about the Premises which will
in any way obstruct or interfere with the rights of other tenants of the
Building, or injure or annoy them, or use or allow the Premises to be used for
any unlawful purpose, nor shall Lessee cause, maintain or permit any nuisance
in, on, or about the Premises or commit or suffer to be committed any waste in,
on, or about the Premises.

Notwithstanding anything to the contrary in this paragraph, Lessor understands
and agrees that Lessee intends to locate computers, servers, and other equipment
in a secure climate-controlled portion of the Premises in a

                                       -3-

manner similar to other web hosting services. Lessee also requires sufficient
electrical capacity to the Premises for the operation of normal office equipment
as well as the computer equipment and air conditioning equipment for the
climate-controlled room in the Premises. Lessor hereby consents to Lessee's use
of the Premises and installation of the equipment as described in this paragraph
and agrees that Lessee shall not be liable for any additional costs, other than
electricity which shall be separately metered to the Premises.

6.   Services.

     (a) Lessor shall, during the term of this Lease and at its sole cost and
expense, be responsible for conforming the Building and all Building systems
outside the Premises (including, without limitation, elevators and fire, safety,
and security systems) to applicable governmental requirements, including those
of environmental laws and regulations and the Americans With Disabilities Act.

     (b) Lessor shall maintain the public and common areas of the Buildings
including the lobbies, stairs, elevators, corridors and restrooms, the exterior
windows of the Building, the heating, ventilating and air-conditioning systems,
the mechanical, plumbing and electrical equipment serving the Building, and the
structure itself in a manner and condition suitable for comparable office
buildings in downtown San Francisco, except for damage caused by the willful or
grossly negligent act of Lessee, which damage shall be repaired by Lessor at
Lessee's expense.

     (c) The Premises shall be separately metered for all utilities, including
water and electricity, provided to the Premises. Lessee shall be responsible for
providing and paying for all utilities and services to the Premises, including,
without limitation, electricity, gas, and water. Lessee shall during the term of
this Lease contract directly for, and pay for, garbage disposal, janitorial, and
window cleaning services. Notwithstanding the foregoing, it is agreed that there
are certain utility costs related to the central air conditioning system and the
common areas of the building (including elevators and lighting for the common
area lobby) that are impossible or impractical to meter separately, and Lessee
agrees to pay Lessee's percentage share of such costs within ten (10) days after
receipt of a billing therefor from Lessor.

     (d) Lessor shall not be in default hereunder or be liable for any damages
directly or indirectly resulting from, nor shall the rental herein reserved be
abated by reason of, (i) the installation, use or interruption of use of any
equipment in connection with the furnishing of any of the foregoing services,
(ii) failure to furnish or delay in furnishing any such services when such
failure or delay is caused by accident or any condition beyond the reasonable
control of Lessor or by the reasonable making of repairs or improvements to the
Premises or to the Building, or (iii) the limitation, curtailment, rationing or
restrictions on use of water, electricity, gas or any other form of energy
serving the Premises or the Building. None of the foregoing events shall be
construed as a constructive or other eviction of Lessee. Lessor shall use
reasonable efforts diligently to remedy any interruption in the furnishing of
such services.

     (e) Lessee shall not install or use heat-generating machines, lighting
other than building standard or other equipment which may affect the temperature
otherwise maintained by the heating, air conditioning and ventilation system,
office machines using more than 220 volts, or equipment causing the connected
electrical load in the Premises to exceed 15 watts per square

                                      -4-

foot, without the prior consent of Lessor, not to be unreasonably withheld or
delayed. Lessor makes no representation with respect to the adequacy or fitness
of the electrical, heating, air conditioning or ventilation equipment in the
Building to accommodate or maintain temperatures which may be required for any
equipment other than ordinary office equipment, or for any equipment exceeding
the maximum voltage or wattage referred to above, and Lessor shall have no
liability for loss or damage suffered by Lessee or others in connection
therewith, except as provided in Paragraph 5 above. If Lessee installs lighting
requiring power in excess of that required for normal office use in the Building
or if Lessee installs equipment requiring power in excess of that required for
normal office equipment or normal copying equipment, Lessee shall pay for the
cost of such excess power as additional rent, together with the cost of
installing any additional risers or other facilities that may be necessary to
furnish such excess power to the Premises; which cost shall include, without
limitation.

7.   Impositions Payable by Lessee. In addition to the monthly rental and other
charges to be paid by Lessee hereunder, Lessee shall pay before delinquency or
reimburse Lessor for any and all of the following, whether or not now customary
or in the contemplation of the parties hereto (collectively, the "Impositions"):
taxes (other than local, state and federal personal or corporate income taxes
measured by the net income of Lessor from all sources), assessments (including,
without limitation, all assessments for public improvements, services or
benefits, irrespective of when commenced or completed), excises, levies,
business taxes, license permit, inspection and other authorization fees, transit
development fees assessments or charges for housing funds, service payments in
lieu of taxes and any other fees or charges of any kind, which are levied,
assessed, confirmed or imposed by any public authority, but only to the extent
the Impositions are: (a) upon, measured by or reasonably attributable to the
cost or value of Lessee's equipment, furniture, fixtures and other personal
property located in the Premises or by the cost or any leasehold improvements
made in or to the Premises by or for Lessee, regardless of whether title to such
improvements shall be in Lessee or Lessor, (b) upon or measured by the monthly
rental or other charges payable hereunder including, without limitation, any
gross income tax or excise tax levied by the City and County of San Francisco,
the State of California the Federal Government or any other governmental body
with respect to the receipt of such rental; (c) upon with respect to or by
reason of the development, possession, leasing operation, management,
maintenance, alteration, repair, use or occupancy by Lessee of the Premises or
any portion thereof; (d) upon this, transaction or any document to which Lessee
is a party creating or transferring an interest or an estate in the Premises. In
the event that it shall not be lawful for Lessee to reimburse Lessor for all or
any part of such Impositions, the monthly rental payable to Lessor under this
Lease shall be revised to net Lessor the same net rental after imposition of any
such Impositions by Lessor as would have been payable to Lessor prior to the
payment of any such Imposition.

8.   Work to be Performed by Lessor Prior to Commencement of Term; Tenant
     Improvements; Allowance.

     (a) Prior to the commencement of the term of this Lease, Lessor shall, at
Lessor's sole cost and expense, have performed the base building work described
in Exhibit "A" hereto.

                                      -5-

     (b) In the event that Lessee selects Birmingham Builders, Inc. to perform
tenant improvements at the Premises as provided herein, Lessee shall, at its
sole cost and expense, cause to be prepared and submit to Lessor by no later
than May 31, 1999 fully scaled, dimensioned, and integrated architectural and
engineering drawings for tenant improvements to the Premises which have been
approved by Lessee and which are of sufficient detail and quality as to be ready
for immediate submission to the City and County of San Francisco Building
Inspection Department. Failure by Lessee to deliver such plans to Lessor by May
31, 1999 shall result in a penalty of one day's rent for each day that the plans
are delayed. This penalty, if incurred, shall be paid in a lump sum at the
commencement date of the lease.

     (c) In the event that a contractor other than Birmingham Builders is
selected by Lessee as contractor for the tenant improvements, rent shall
commence September 1, 1999 regardless of the date of completion of drawings for
the tenant improvements, the completion of construction of the tenant
improvements, or the date Lessee takes occupancy of the space.

     (d) Lessor agrees, upon written request by Lessee made no later than one
hundred eighty (180) days following the commencement date of this lease, to
reimburse Lessee an amount not to exceed $1,503,200.00 for the exclusive purpose
of Lessee's payment of costs of architectural, engineering, and permit fees,
cabling the Premises, Lessee's move into the Premises, and tenant improvements
to the Premises in addition to the base building work to be performed by Lessor.
Lessee shall support its request for such reimbursement by providing Lessor with
documentation evidencing Lessee's obligation to pay such costs, and if Lessee
fails to provide Lessor with such documentation Lessor shall be under no
obligation to provide Lessee with such reimbursement. Lessee shall use such
reimbursement for no purpose other than paying such costs.

9.   Alterations.

     (a) All of Lessee's trade fixtures, furniture, furnishings, equipment and
other movable personal property not permanently affixed to the Premises shall,
subject to the provisions hereof, remain the property of Lessee.

     (b) Lessee shall not make or offer to be made any alterations, additions or
improvements (collectively "alterations") to or of the Premises or any part
thereof, or attach any fixtures or equipment thereto, or cause a building permit
to be issued for any alterations without Lessor's prior consent, which consent
shall not be unreasonably withhold or delayed; provided that, with prior notice
to Lessor but without the necessity of Lessor's consent, Lessee shall have the
right to make non-structural alterations not affecting Building systems and for
which a general construction building permit is not required. Any alterations to
the Premises shall be made by Lessee at Lessee's sole cost and expense. The
contractor selected by Lessee to make any alterations to the Premises must be
reasonably approved in writing by Lessor prior to commencement of any work and
such contractor shall at all times be subject to Lessor's reasonable control
while in the Building. Lessee shall be responsible for any additional
alterations required by law to be made by Lessor to or in the Building as a
result of any alterations to the Premises made by or for Lessee. All alterations
and fixtures, including, but not limited to, carpeting, other affixed floor
coverings, paneling, and cabling for built-in security systems made in or upon
the Premises either by or for Lessee and affixed to or forming a part of

                                      -6-

the Premises, shall immediately upon installation or construction become
Lessor's property free and clear of all liens and encumbrances.

     (c) Lessee shall have the right to place and maintain a neat and
appropriate sign of the name of Lessee's business on the Green Street facade of
the building, provided Lessor consents in writing to the shape, size, color and
location thereof. Lessor shall not unreasonably withhold or delay such consent.
Lessee upon request of Lessor shall immediately remove any sign or decoration
which Lessee has placed or permitted to be placed upon the exterior of the
premises or upon the windows facing any street upon which the premises abut
without the consent of Lessor and which, in the opinion of Lessor, is
inappropriate or objectionable and, if Lessee fails so to do, Lessor, in
addition to any rights it may have hereunder, may enter upon the premises and
remove such sign without liability whatsoever. Lessee agrees that its signage
will comply with all applicable governmental requirements. Lessor expressly
reserves the exclusive right to the use of the exterior side walls, rear walls,
and roof of the demised premises and Lessee shall not be permitted to place any
sign or advertisement thereon or any other matter or property without the
written consent of Lessor.

     (d) Upon the expiration or any sooner termination of this Lease, Lessee
shall remove or cause to be removed at its expense (i) all of Lessee's personal
property described in paragraph 8(a) above, (ii) all telephone, data processing,
audio and video, security, and electrical (other than Building standard)
improvements installed by or for Lessee, and (iii) any alterations, additions,
fixtures, or improvements installed in the Premises by or for Lessee; provided
that, in the case of an item described in clause (ii) or (iii) above, Lessor
shall have notified Lessee at the time Lessor consented to its installation that
Lessor would require removal of the item. Lessee shall repair at its expense all
damage to the Premises and the Building caused by the removal of any of the
items described in this paragraph, reasonable wear and tear and damage by fire
or other casualty (other than damage caused by the willful or grossly negligent
act of Lessee) excepted. Lessee shall not remove any fixtures from the Premises
without Lessor's prior written consent if such removal would impair any
structural elements of the Building or would damage any improvements within the
Premises. Any personal property described in this paragraph not removed from the
Premises by Lessee upon the expiration or sooner termination of this Lease,
shall, at Lessor's option, become the property of Lessor, or Lessor may remove
or cause to be removed such property for Lessee's account, and Lessee shall
reimburse Lessor for the cost of removal (including the reasonable cost of
repairing any damage to the Premises or the Building caused by removal) and
storage and a reasonable charge for Lessor's overhead, within ten (10) days
after receipt of a statement therefor. Lessee's obligations under this paragraph
shall survive the termination of this Lease.

10.  Liens. Lessee shall keep the Premises and the Building free from any liens
arising out of any work performed, materials furnished or obligations incurred
by Lessee. In the event that Lessee shall not, within 10 business days following
notice to Lessee of the imposition of any such lien, cause the same to be
released of record (whether by means of posting a bond or otherwise), Lessor
shall have, in addition to all other remedies provided herein and by law, the
right but not the obligations to cause the same to be released by means of
posting a bond or causing the same to be released by such means as it shall deem
proper, including payment of the claim giving rise to such lien. All sums paid
by Lessor for such purposes, and all expenses incurred by it in connection
therewith, shall be payable to Lessor by Lessee immediately upon

                                      -7-

demand. Lessor shall have the right to post and keep posted on the Premises any
notices that may be provided by law or which Lessor may deem to be proper for
the protection of Lessor, the Premises and the Building from such liens, and
Lessee shall give Lessor at least five (5) days' prior notice of the date of
commencement of any construction on the Premises in order to permit the posting
of such notices.

11. Repairs. By entry hereunder Lessee accepts the Premises as being in the
condition in which Lessor is obligated to deliver the Premises, subject only to
latent or seasonal defects of which Lessee notifies Lessor within 12 months
following the date Lessee takes occupancy of the Premises. Lessee shall, at all
times during the term hereof and at Lessee's sole cost and expense, keep the
Premises and every part thereof in good condition and repair, ordinary wear and
tear and damage thereto by fire, earthquake, act of God or the elements
excepted, Lessee hereby waiving all rights to make repairs at the expense of
Lessor or in lieu thereof to vacate the Premises as provided by California Civil
Code Section 1942 or any other similar law, statute or ordinance now or
hereafter in affect. All repairs and replacements made by or on behalf of Lessee
hereunder shall be made and performed at Lessee's cost and expense and at such
time and in such manner as Lessor may reasonably designate by contractors or
mechanics reasonably approved by Landlord and so that the same shall be at least
equal in quality, value, character and utility to the original work or
installation being repaired or replaced. Lessee shall at the end of the term
hereof surrender to Lessor the Premises and all alterations, additions and
improvements thereto in the same condition as when received, ordinary wear and
tear and damage by fire, earthquake, act of God or the elements excepted. Lessor
has no obligation and has made no promise to alter, remodel, improve, repair,
decorate or paint the Premises or any part thereof, except as specifically
herein set forth. No representations respecting the condition of the Premises or
the Building have been made by Lessor to Lessee.

12.  Destruction or Damage.

     (a) In the event the Premises or the portion of the Building necessary for
Lessee's occupancy are damaged by first earthquake, act of God, the elements or
other casualty, Lessor shall forthwith repair the same, subject to the
provisions of this paragraph 10 hereinafter set forth, if such repairs can, in
Lessor's reasonable opinion, be made within 90 days and if insurance proceeds
are available to pay the full replacement cost thereof. This Lease shall remain
in full force and effect except that, if and to the extent that such damage is
not the result of the gross negligence or willful misconduct of Lessee or
Lessee's employees or invitees, an abatement of rental shall be allowed Lessee
for such part of the Premises as shall be rendered unusable by Lessee in the
conduct of its business during the time such part is so unusable.

     (b) If such repairs cannot, in Lessor's reasonable opinion, be made within
90 days, or if sufficient insurance proceeds are not available to pay the full
replacement cost thereof, Lessor may elect upon notice to Lessee within 30 days
after the date of such fire or other casualty, to repair or restore such damage,
in which event this Lease shall continue in full force and effect, but the rent
shall be abated as provided above in this paragraph. If in the reasonable
opinion of Lessor's contractor, which opinion shall be rendered within 45 days
of the date of damage or destruction, the damage or destruction cannot be
repaired so as to allow Lessee to reoccupy the Premises within 120 days after
such damage or destruction occurs (without regard to the issuance of a building
permit or any governmental delays), either Lessor or Lessee may terminate this
                                      -8-

Lease by notice to the other given within 30 days after receiving notice of such
determination. If Lessor does not elect to make such repairs, this Lease shall
terminate as of the date of such fire or other casualty.

     (c) A total destruction of the Building shall automatically terminate this
Lease. Lessee waives California Civil Code Sections 1932(2) and 1933(4)
providing for termination of hiring upon destruction of the thing hired.

     (d) If the Premises are to be repaired under this paragraph, Lessor shall
repair at its cost any injury or damage to the structural portions of the
Building, Building systems, and all leasehold improvements, in the Premises
other then alterations, additions or improvements made by or for Lessee. Lessee
shall pay the cost of repairing any alterations, additions or improvements made
by or for Lessee and the cost of repairing or replacing Lessee's fixtures and
personal property in the Premises.

13.  Insurance.

     (a) Lessee shall obtain and maintain during the term of this Lease
commercial general liability insurance with a combined single limit for bodily
injury and property damage in an amount not less than $2,000,000, and employer's
liability and workers' compensation insurance as required by law. If Lessee's
insurance contains a split limit of liability the liability limit shall be not
less than $2,000,000 for bodily injury and $1,000,000 for property damage. Such
insurance policy shall also cover Lessee's indemnity obligations set forth
below. Lessee's commercial general liability insurance policy shall be an
occurrence basis and shall be endorsed to provide that (i) it may not be
cancelled or altered in such a manner as adversely to affect the coverage
afforded thereby without 30 days' prior written notice to Lessor, (ii) Lessor is
named as additional insured, (iii) such insurance is primary with respect to
Lessor and that any other insurance maintained by Lessor is excess and
noncontributing with such insurance, (iv) it shall contain cross-liability
endorsements and (v) it shall contain a waiver of subrogation as provided below.
Lessee shall insure all personal property and fixtures of Lessee and all
improvements made by or for Lessee to the Premises. If, in the reasonable
opinion of Lessor's insurance advisor, based on a substantial increase in
recovered liability claims generally, the specified amounts of coverage are no
longer adequate, such coverage shall be appropriately increased to an amount
comparable to that required by prudent owners of comparable, similarly situated
buildings in the San Francisco area. Prior to the commencement of the term, a
duplicate of such policy or a duplicate certificate thereof shall be delivered
to Lessor for retention by it. If Lessee fails to obtain such insurance or to
furnish Lessor any such duplicate policy or certificate as herein required,
Lessor may, at its election, with not less than 10 days' prior notice to Lessee
but without any obligation so to do, procure and maintain such coverage and
Lessee shall reimburse Lessor on demand as additional rent for any premium so
paid by Lessor. The insurance required under this paragraph and all renewals
thereof shall be issued by such good and responsible insurance companies
qualified to do and doing business in the State of California as may be approved
by Lessor, which approval shall not be unreasonably withheld. Lessee shall have
the right to provide all insurance required herein pursuant to blanket policies
so long as the coverage applicable to the Premises or afforded Lessor will not
be reduced or diminished by reason of the use of such blanket, policies and so
long as all other requirements of this paragraph are satisfied.

                                      -9-

     (b) Lessor shall obtain and keep in force during the term of this Lease a
policy of Combined Single Limit Bodily Injury and Broad Form Property Damage
insurance plus coverage against such other risks Lessor deems advisable from
time to time, insuring Lessor, but not Lessee, against liability arising out of
the ownership, use, occupancy or maintenance of the Building in amounts
customary for properties comparable to the Building in downtown San Francisco.
The policy required herein shall contain such deductibles as Lessor or the
aforesaid lender may determine.

14. Waiver of Subrogation. Notwithstanding anything to the contrary contained
herein, to the extent of insurance proceeds received with respect to the loss,
Lessee and Lessor each hereby waive any right of recovery against the other
party for any loss or damage maintained by such other party with respect to the
Building, the Premises, the contents of same or any operation therein, whether
or not such loss is caused by the fault or negligence of such other party.
Lessor and Lessee shall each obtain from their respective insurers under all
policies of fire, theft, public liability, and other insurance maintained by
either of them (excluding worker's compensation) at any time during the term
hereof insuring or covering the Building, the Premises or any portion thereof or
operations therein, a waiver of all rights of subrogation which the insurer of
one party might have against the other party, and Lessor and Lessee shall each
indemnify the other against any loss or expense, including reasonable attorneys'
fees, resulting from the failure to obtain such waiver.

15.  Indemnification. Lessee hereby waives all claims against Lessor for damage
to any property or injury or death of any person in, upon or about the Premises
arising at any time and from any cause other than by reason of the gross
negligence or willful act of Lessor, its contractors, employees or agents, and
Lessee shall indemnify and hold Lessor harmless from any damage to any property
or injury to or death of any person arising from the use of the Premises or the
Building by Lessee, its agents, employees, contractors and invitees, except to
the extent caused by the gross negligence or willful act of Lessor, its
contractors, employees or agents. Lessor hereby waives all claims against Lessee
for damage to or destruction of any property or injury to or death of any person
in, on, or about the areas of the Building other than the Premises arising at
any time and from any cause other than by reason of the gross negligence or
willful act of Lessee or any of its employees, agents, or contractors, and
Lessor shall indemnify and hold Lessee harmless against all liability for death
or injury to person and damage to property caused by the gross negligence or
willful act of Lessor or any of its employees, agents, or contractors. The
foregoing indemnity obligations shall include reasonable attorneys' fees,
investigation costs and all other reasonable costs and expenses incurred by the
indemnified party from the first notice that any claim or demand is to be made
or may be made. The provisions of this paragraph shall survive the termination
of this Lease with respect to any damage, injury or death occurring prior to
such termination.

16.  Compliance with Legal Requirements. Lessee shall at its sole cost and
expense promptly comply with all laws, statutes, ordinances and governmental
rules regulations or requirements which may hereafter be in force, with the
requirements of any governmental body now or hereafter constituted prescribing
fire protection standards, with any direction or occupancy certificate issued
pursuant to any law by any public officer or officers, as well as the provisions
of all recorded documents affecting the Premises, insofar as any thereof relate
to or affect the condition, use or occupancy of the Premises by Lessee,
excluding alterations or improvements to

                                      -10-

the Building as a whole or the premises of tenants generally that are not by law
the responsibility of tenants to comply with and are not required as a result of
Lessee's particular use of the Premises (as opposed to general office use).
Lessee shall indemnify and hold Lessor harmless from any and all demands,
claims, losses or damages suffered by Lessor as a result of Lessee's failure to
perform the foregoing covenant.

17.  Assignment and Subletting.

     (a) Lessee shall not, without the prior written consent of Lessor (which
consent shall not be unreasonably withheld or delayed), assign this Lease or any
interest herein, sublet the Premises or any part thereof, permit the use or
occupancy of the Premises by any person other than Lessee, or hypothecate this
Lease or any interest herein. Any of the foregoing acts without such consent
shall be void and shall, at the option of Lessor, constitute a default that
shall entitle Lessor to terminate this Lease. Notwithstanding the foregoing,
Lessee shall be permitted to assign all or a portion of its interest in this
Lease or sublet all or a portion of the Premises to an affiliate of Lessee (as
defined below), with notice to Lessor but without the necessity of Lessor's
consent, provided (i) Lessee is not then in default under the terms of this
Lease beyond the expiration of the applicable grace or cure period, if any, and
(ii) in the event of an assignment, only, any such affiliate agrees to assume
all of Lessee's obligations under this Lease. For purposes of the immediately
preceding sentence, an affiliate of Lessee shall mean (1) a corporation which
controls Lessee, is controlled by Lessee or its principals, or is under common
control with Lessee or its principals or (2) any entity merged into or merging
with Lessee or into which Lessee is merged or which acquires all of Lessee's
assets as a going concern of the business that is being conducted on the
Premises. Any such consent by Lessor shall not release Lessee from any of
Lessee's obligations hereunder or be deemed to be a consent to any subsequent
hypothecation, assignment, subletting, occupation or use by another person. This
Lease shall not, nor shall any interest herein, be assignable as to the interest
of Lessee involuntarily or by operation of law without the prior written consent
of Lessor. Lessee agrees that the instrument by which any assignment or
subletting consented to by Lessor is accomplished shall be in a form reasonably
satisfactory to Lessor and shall expressly provide that the assignee or
subtenant will perform and observe all the agreements, covenants, conditions and
provisions arising from and after such assignment or sublease to be performed
and observed by Lessee under this Lease as and when performance and observance
in due, that no assignee or subtenant shall have the further right to assign or
sublet with Lessor's prior consent, not to be unreasonably withheld, and that
Lessor shall have the right to enforce such agreements, covenants, conditions
and provisions directly against such assignee or subtenant. Lessee shall in all
cases remain responsible for the performance by any subtenant or assignee as
indicated thereon of all such agreements, covenants, conditions and provisions.
Any assignment or subletting without an instrument containing the foregoing
provision shall be void and shall, at the option of Lessor, constitute a default
that entitles Lessor to terminate this Lease.

     (b) Notwithstanding the foregoing, before entering into any assignment of
this Lease or into a sublease of all or part of the Premises, Lessee shall give
written notice to Lessor identifying the intended assignee or subtenant by name
and address, the terms of the intended assignment or sublease, and the nature of
the business of the proposed assignee or sublessee, together with current
audited or reviewed financial statements for the proposed assignee or sublessee
to the extent available, and, thereafter, any other information which Lessor
shall

                                      -11-

reasonably request that is readily available to the proposed subtenant or
assignee in the ordinary course of business. For a period of 15 days after such
notice is given, Lessor shall have the right by written notice to Lessee (but
not in the case of an assignment or subletting to an affiliate pursuant to
subparagraph (a) above for which Lessor's consent is not required) to (i) in the
case of a proposed sublease of one floor or more of the Premises, either (A)
sublet from Lessee any portion of the Premises proposed to be sublet for the
term for which such portion is proposed to be sublet but at the same rent as
Lessee is required to pay to Lessor under this Lease for the same spaces
computed on a pro rata square footage basis, or (B) if the proposed subletting
is for substantially the remaining period of the term of this Lease, terminate
this Lease, or terminate this Lease as it pertains to the portion of the
Premises so proposed by Lessee to be sublet, or (ii) in the case of a proposed
assignment, terminate this Lease. If Lessor so terminates this Lease, such
termination shall be as of the date specified in such notice. If Lessor so
terminates this Lease, Lessor may, if it elects, enter into a new lease covering
the Premises or a portion thereof with the intended assignee or subtenant on
such terms as Lessor and such person may agree, or enter into a new lease
covering the Premises or a portion thereof with any other person; in such event,
Lessee shall not be entitled to any portion of the profit, if any, which lessor
may realize on account of such termination and reletting. Lessor's exercise of
its aforesaid option shall not be construed to impose any liability upon Lessor
with respect to any real estate brokerage commission(s) or any other costs or
expenses incurred by Lessee in connection with its proposed subletting or
assignment.

     (c) If Lessee complies with the foregoing provisions of this paragraph, and
Lessor does not exercise an option provided to Lessor under subparagraph (b) of
this paragraph, Lessor's consent to a proposed assignment or sublet shall not be
unreasonably withheld and shall be given, or the specific reasons for denial
thereof shall be stated, within 15 days following Lessee's request therefor.
Without limiting the other instances in which it may be reasonable for Lessor to
withhold its consent to an assignment or subletting, Lessor and Lessee
acknowledge that it shall be reasonable for Lessor to withhold its consent in
the following instances:

          (1) the proposed assignee or sublessee is a governmental agency;

          (2) in Lessor's reasonable judgment, the use of the Premises by the
     proposed assignee or sublessee would involve occupancy by other than
     primarily general office personnel or otherwise be in violation of this
     Lease, would entail any alterations which would lessen materially the value
     of the leasehold improvements in the Premises, or would require materially
     increased services by Lessor;

          (3) in Lessor's reasonable judgment, the financial worth of the
     proposed assignee or sublessee does not meet the credit standards applied
     by Lessor for other tenants under leases with comparable terms;

          (4) in Lessor's reasonable judgment, the proposed assignee or
     sublessee does not have a good reputation as a tenant of property;

                                      -12-

          (5) Lessor has experienced previous repeated, material defaults by or
     is in litigation with the proposed assignee or subtenant;

          (6) in Lessor's reasonable judgment, the Premises, or the relevant
     part thereof, will be used in a manner that will violate any pre-existing
     negative covenant as to use contained in any other lease of space in the
     Building;

          (7) the use of the Premises by the proposed assignee or subtenant will
     violate any applicable law, ordinance or regulation;

          (8) the proposed assignment or sublease will create a vacancy
     elsewhere in the Building with respect to comparable space in the Building;

          (9) the proposed assignee or subtenant is a person with whom Lessor is
     negotiating to lease space in the Building;

          (10) the proposed assignment or sublease fails to include all of the
     terms and provisions required to be included therein pursuant to this
     paragraph 16;

          (11) Lessee is in default of any obligation of Lessee under this Lease
     beyond the expiration of the applicable grace or cure period, if any, or
     Lessee has defaulted under this Lease beyond the expiration of the
     applicable grace or cure period, if any, an two or more occasions during
     the IS months preceding the date that Lessee shall request consent; or

          (12) in the case of a subletting of less then the entire Premises if
     the subletting would result in the division of any floor of the Premises
     into two or more subparcels or would require access to be provided through
     space leased or held for lease to another tenant or improvements to be made
     outside of the Premises.

     (d) In the case of an assignment, one-half of any sums or other economic
consideration received by Lessee as a result of such assignment shall be paid to
Lessor after first deducting the unamortized cost of leasehold improvements paid
for by Lessee (including demising costs), and the cost of any attorneys' fees,
advertising expenses, and real estate commissions incurred in connection with
such assignment. In the case of a subletting, one-half of any, sum or economic
consideration received by Lessee as a result of such subletting shall be paid to
Lessor after first deducting (1) the rental due hereunder, prorated to reflect
only rental allocable to the sublet portion of the Premises, (2) the cost of
leasehold improvements (including demising costs) made to the sublet portion of
the Premises at Lessee's cost, amortized over the term of this Lease, except for
leasehold improvements made for the specific benefit of the sublessee, which
shall be amortized over the term of the sublease, and (3) the cost of any
attorneys' fees, advertising expenses, and real estate commissions incurred in
connection with such subletting, amortized over the term of the sublease.

                                      -13-

     (e) If Lessee shall assign or sublet the Premises, or request the consent
of Lessor to any assignment or subletting, or if Lessee shall request the
consent of Lessor for any act that Lessee proposes to do, then Lessee shall pay
Lessor's reasonable attorneys' fees incurred in connection therewith.

18. Entry by Lessor. Lessor may enter the Premises at reasonable hours and,
except in case of emergency or the provision of routine janitorial services,
upon reasonable prior notice (which, notwithstanding anything to the contrary
contained herein, may be oral), in order to (a) inspect the same, (b) exhibit
the same to prospective purchasers, lenders or, during the last 12 months of the
term hereof, tenants, (c) determine whether Lessee is complying with all its
obligations hereunder, (d) supply janitorial service and any other service to be
provided by Lessor to Lessee hereunder, (e) post notices of nonresponsibility,
(f) post "to Lease" signs of reasonable size upon the Premises during the final
90 days of the term hereof, and (g) make repairs required of Lessor under the
terms hereof or repairs to any adjoining space or utility services or to make
repairs, alterations or improvements to any other portion of the Building;
provided, however, that all such work shall be done as promptly as is reasonably
possible and so as to cause as little interference to Lessee as is reasonably
possible, and provided further that Lessor shall not store materials within the
Premises for more than 2 business days in any 12-month period. Lessee hereby
waives any claims for damages for any injury or inconvenience to or interference
with Lessee's business, any loss of occupancy or quiet enjoyment of the Premises
or any other loss occasioned by such reasonable entry. Lessor shall at all times
have and retain a key with which to unlock all of the doors in, on or about the
Premises (excluding Lessee's vaults, safes and similar areas designated by
Lessee); and Lessor shall have the right to use any and all means which Lessor
may deem proper to open said doors in an emergency only in order to obtain entry
to the Premises, and any emergency entry to the Premises obtained by Lessor by
any of said means, or otherwise, shall not under any circumstances be construed
or deemed to be a forcible or unlawful entry into or a detainer of the Premises
or an eviction, actual or constructive, of Lessee from the Premises, or any
portion thereof.

19.  Events of Default. The occurrence of any one or more of the following
events ("Events of Default") shall constitute a breach of this Lease by Lessee:
(a) if Lessee shall fail to pay rental or any other sum due hereunder when and
as the same becomes due and payable and such failure shall continue for more
than five (5) days after notice by Lessor, provided that if Lessee shall have
failed twice or more in any calendar year to pay rent when due and notice of
such default shall have been given by Lessor in two or more such instances, no
notice by Lessor shall thereafter be required hereunder for the remainder of
such calendar year; or (b) if Lessee shall fail to perform or observe any other
term hereof to be performed or observed by Lessee, and such failure shall
continue for more than 30 days after notice thereof by Lessor, or, if the
failure is not susceptible of cure within 30 days, 90 days provided that Lessee
commences to cure within 30 days following Lessor's notice and prosecutes with
due diligence and dispatch the curing of such default; or (c) if Lessee shall
make a general assignment for the benefit of creditors, shall become insolvent
or shall admit in writing its inability to pay its debts as they become due or
shall file a petition in bankruptcy, or shall be adjudicated as bankrupt or
insolvent, or shall file a petition in any proceeding seeking any
reorganization, arrangement, composition, readjustment, liquidation, dissolution
or similar relief under any present or future statute law or regulation, or
shall file an answer admitting or fail timely to contest the material
allegations of a petition filed against it in any such proceeding, or shall seek
or consent to or

                                      -14-

acquiesce in the appointment of any trustee, receiver or liquidation of Lessee
or any material part of its properties; or (d) if within 90 days after the
commencement of any proceeding against Lessee seeking any reorganization,
arrangement, composition, readjustment, liquidation, dissolution or similar
relief under any present or future statute, law or regulation, such proceeding
shall not have been dismissed, or if, within 90 days after the appointment
without the consent or acquiescence of Lessee, of any trustee, receiver or
liquidator of Lessee or of any material part of its properties, such appointment
shall not have been vacated; or (e) if this Lease or any estate of Lessee
hereunder shall be levied upon under any attachment or execution and such
attachment or execution is not vacated within 10 days after notice thereof to
Lessee; or (f) Lessee shall vacate or abandon the Premises without payment of
rent.

20.  Termination Upon Default.

     (a) If an Event of Default shall occur, Lessor at any time thereafter may
give a written termination notice to Lessee, and on the date specified in such
notice Lessee's right to possession shall terminate and this Lease shall
terminate, unless on or before such date all arrears of rental and all other
sums payable by Lessee under this Lease and all costs and expenses incurred by
or on behalf of Lessor hereunder shall have been paid by Lessee and all other
breaches of this Lease by Lessee at the time existing shall have been fully
remedied to the satisfaction of Lessor. Upon such termination, Lessor may
recover from Lessee: (a) the worth at the time of award of the unpaid rental
which had been earned at the time of termination; (b) the worth at the time of
award of the amount by which the unpaid rental which would have been earned
after termination until the time of award exceeds the amount of such rental loss
that Lessee proves could have been reasonably avoided; (c) the worth at the time
of award of the amount by which the unpaid rental for the balance of the term of
this Lease after the time of award exceeds the amount of such rental loss that
Lessee proves could be reasonably avoided; and (d) any other amount necessary to
compensate Lessor for all the detriment proximately caused by Lessee's failure
to perform its obligations under this Lease or which in the ordinary course of
things would be likely to result therefrom. The "worth at the time of award" of
the amounts referred to in clauses (a) and (b) above is computed by allowing
interest at the rate of 10% per annum or, if a higher rate is legally
permissible, at the highest rate legally permitted. The "worth at the time of
award" of the amount referred to in clause (c) above is computed by discounting
such amount at the discount rate of the Federal Reserve Bank of San Francisco at
the time of award plus 1%. For purposes of this paragraph, all rental sums shall
be computed an the basis of the average monthly amount thereof accruing during
the 24-month period immediately preceding the occurrence of an event of default
unless a 24-month period of this Lease has not elapsed, in which case the
average monthly amount shall be based upon the entire period of Lessee's
occupancy of the Premises. As used herein, the "time of the award" shall be
deemed to be the time of entry of judgment on Lessor's claim or the similar
point of determination if the matter is determined by a tribunal other than a
court. The amount recoverable by Lessor pursuant to subsection (d) above shall
include, but shall not be limited to, any reasonable costs or expenses incurred
by Lessor in maintaining or preserving the Premises after such default,
preparing the Premises for reletting to a new tenant, accomplishing any repairs
or alterations to the Premises for the purpose of such reletting, rectifying any
damage thereto occasioned by the act or omission of Lessee and any other cost
reasonably necessary or appropriate to relet the Premises.

                                      -15-

     (b) Lessee hereby waives all rights under California Code of Civil
Procedure Section 1179 and California Civil Code Section 3275 providing for
relief from forfeiture, and any other right now or hereafter existing to redeem
the Premises or reinstate this Lease after termination pursuant to this
paragraph or by order or judgment of any court or by any legal process.

     (c) IT IS MUTUALLY AGREED BY AND BETWEEN LESSOR AND LESSEE THAT THE
RESPECTIVE PARTIES HERETO SHALL AND THEY HEREBY DO WAIVE TRIAL BY JURY IN ANY
ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY EITHER OF THE PARTIES HEREBY
AGAINST THE OTHER ARISING OUT OF OR IN ANY WAY CONNECTED WITH THIS LEASE, THE
RELATIONSHIP OF LESSOR AND LESSEE, LESSEE'S USE OR OCCUPANCY OF THE PREMISES,
AND ANY STATUTORY OR ANY OTHER STATUTORY REMEDY.

21. Continuation After Default. Even though Lessee has breached this Lease and
abandoned the Premises without payment of rent, this Lease shall continue in
effect for so long as Lessor does not terminate Lessee's right to possession,
and Lessor may enforce all its rights and remedies under this Lease, including
the right to recover the rental as it becomes due under this Lease. Acts of
maintenance or preservation or efforts to relet the Premises or the appointment
of a receiver upon initiative of Lessor to protect Lessor's interest under this
Lease shall not constitute a termination of Lessee's right to possession.

22.  Other Relief. The remedies provided to Lessor in this Lease shall be
cumulative and are in addition to any other remedies available to Lessor at law
or in equity by statute or otherwise.

23.  Lessor's Right to Cure Defaults. All agreements and provisions to be
performed by Lessee under any of the terms of this Lease shall be at its sole
cost and expense and without any abatement of rental. If Lessee shall fail to
pay any sum of money, other than rental, required to be paid by it hereunder or
shall fail to perform any other act on its part to be performed hereunder and
such failure shall continue for 30 days after notice thereof by Lessor, Lessor
may, but shall not be obligated so to do, and without waiving or releasing
Lessee from any obligations of Lessee, make any such payment or perform any such
other act on Lessee's part to be made or performed as in this Lease provided.
All reasonable sums so paid by Lessor and all necessary incidental costs shall
be deemed additional rent hereunder and shall be payable to Lessor on demand,
and Lessor shall have (in addition to any other right or remedy of Lessor) the
same rights and remedies in the event of the nonpayment thereof by Lessee as in
the case of default by Lessee in the payment of rental.

24.  Attorneys' Fees. If either party commences an action or proceeding against
the other party arising out of or in connection with this Lease, or institutes
any proceeding in a bankruptcy or similar court which has jurisdiction over the
other party or any or all of its property or assets, the prevailing party in
such action or proceeding and in any appeal in connection therewith shall be
entitled to have and recover from the unsuccessful party reasonable attorneys'
fees, court costs, expenses and other costs of investigation and preparation. If
such prevailing party recovers a judgment in any such action, proceeding, or
appeal, such attorneys' fees, court costs and expenses shall be included in and
as a part of such judgment.

                                      -16-

25.  Eminent Domain. If all or any part of the Premises shall be taken as a
result of the exercise of the power of eminent domain, this Lease shall
terminate as to the part so taken as of the date of taking. In the case of a
partial taking, either Lessor or Lessee shall have the right to terminate this
Lease as to the balance of the Premises by delivering a written notice to the
other within 30 days after the date of taking, provided, however, that a
condition to the exercise by Lessee of such right to terminate shall be that the
portion of the Premises taken shall be of such extent and nature as to render
the remaining portion thereof untenantable and unusable by Lessee. The Lease
shall terminate as of the date thirty (30) days after delivery by either party
of a termination notice. In the event of any taking, Lessor shall be entitled to
any and compensation, damages, income, rent, awards, or any interest therein
whatsoever which may be paid or made in connection therewith, and Lessee shall
have no claim against Lessor for the value of any unexpired term of this Lease
or otherwise. In the event of a partial taking of the Premises which does not
result in a termination of this Lease, the monthly rental thereafter to be paid
shall be abated in proportion to the percentage of the Premises taken or
substantially impaired by such taking.

26. Subordination. This Lease shall be subject and subordinated at all times to
(1) all ground or underlying leases which may hereafter be executed affecting
the Building, and (2) the lien of all mortgages and deeds of trust in any amount
or amounts whatsoever now or hereafter placed on or against the Building or on
or against Lessor's interest or estate therein or on or against all such ground
or underlying leases, all without the necessity of having further instruments
executed on the part of Lessee to effectuate such subordination. Notwithstanding
the foregoing, (i) in the event of termination for any reason whatsoever of any
such ground or underlying lease, this Lease shall not be barred, terminated, cut
off or foreclosed nor shall the rights and possession of Lessee hereunder be
disturbed if Lessee shall not then be in default in the payment of rental or
other sums beyond the expiration of the applicable grace or cure period or be
otherwise in default beyond the expiration of the applicable grace or cure
period under the terms of this Lease, and Lessee shall attorn to the lessor of
any such ground or underlying lease, or, if requested, enter into a new lease
for the balance of the original or extended term hereof then remaining upon the
same terms and provisions as are in this Lease contained; (ii) in the event of a
foreclosure of any such mortgage or deed of trust or of any other action or
proceeding for the enforcement thereof, or of any sale thereunder, this Lease
will not be barred, terminated, cut off or foreclosed nor will the rights and
possession of Lessee thereunder be disturbed if Lessee shall not then be in
default in the payment of rental or other sums beyond the expiration of the
applicable grace or cure period or be otherwise in default beyond the expiration
of the applicable grace or cure period under the terms of this Lease, and Lessee
shall attorn to the purchaser at such foreclosure, sale or other action or
proceeding; and (iii) Lessee agrees to execute and deliver upon demand such
further instruments evidencing such subordination of this Lease to said deed, to
such ground or underlying leases, and to the lien of any such mortgages or deeds
of trust as may reasonably be required by Lessor. Lessee's covenant to
subordinate this Lease to ground or underlying leases and/or mortgages or deeds
of trust hereafter executed is conditioned upon each such senior instrument
containing the commitments specified in the preceding clauses (i) and (ii) and
the receipt by Lessee of an agreement from the holder of each such senior
instrument confirming such commitments in a form acceptable to such holder.

27.  No Merger. 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

                                      -17-

any existing subleases or subtenancies, or may, at the option of Lessor, operate
as an assignment to it of any or all such subleases or subtenancies.

28.  Sale. In the event the original Lessor hereunder, or any successor owner of
the Building, shall sell or convey the Building, all liabilities and obligations
on the part of the original Lessor, or such successor owner, under this Lease
accruing thereafter shall terminate, and thereupon all such liabilities and
obligations shall be binding upon the new owner. Lessee agrees to attorn to such
new owner.

29.  Estoppel Certificate. At any time and from time to time but on not less
than 10 days' prior written request by either party, the other party will
execute, acknowledge and deliver to the requesting party, promptly upon request,
a certificate certifying (a) that this Lease is unmodified and in full force and
effect (or, if there have been modifications, that this Lease is in full force
and effect, as modified, and stating the date and nature of each modification),
(b) the date, if any, to which rental and other sums payable hereunder have been
paid, (c) that no notice has been received by the certifying party of any
default which has not been cured, except as to defaults specified in said
certificate, and (d) such other matters as may be reasonably requested by the
requesting party. Any such certificates may be relied upon by an prospective
purchaser, mortgagee or beneficiary under any deed of trust on the Building or
any part thereof.

30.  No Light, Air or View Easement. Any diminution or shutting off of light,
air or view by any structure which may be erected on lands adjacent to the
Building shall in no way affect this Lease or impose any liability on Lessor.

31.  Holding Over. If, without the express consent of Lessor, Lessee holds
possession of the Premises after expiration of the term of this Lease, Lessee
shall become a tenant from month to month upon the terms herein specified but at
a monthly rental equivalent to 150% of the then prevailing monthly rental paid
by Lessee at the expiration of the term of this Lease, payable in advance on or
before the first day of each month. Each party shall give the other notice at
least one month prior to the date of termination of such monthly tenancy of its
intention to terminate such tenancy.

32.  Abandonment. Lessee shall not at any time during the term hereof vacate or
abandon the Premises without payment of rent, and if Lessee shall abandon or
surrender the Premises, or be dispossessed by process of law or otherwise, any
personal property belonging to Lessee and left on the Premises shall be deemed
to be abandoned, at the option of Lessor, except such property as may be
mortgaged to Lessor.

33.  Security Deposit. Upon execution of this Lease, Lessee shall deposit with
Lessor a security deposit (the "Deposit") in the amount of $82,300.00. The
Deposit shall be held by Lessor as security for the faithful performance by
Lessee of all the provisions of this Lease to be performed or observed by
Lessee. If Lessee fails to pay rent or other sums due hereunder, or otherwise
defaults with respect to any provision of this Lease, Lessor may use, apply or
retain all or any portion of the Deposit for the payment of any rent or other
sum in default or for the payment of any other sum to which Lessor may become
obligated by reason of Lessee's default, or to compensate Lessor for any loss or
damage which Lessor may suffer thereby. If Lessor so uses or applies all or any
portion of the Deposit, then within 10 days after demand therefor

                                      -18-

Lessee shall deposit cash with Lessor in an amount sufficient to restore the
Deposit to the full amount thereof, and Lessee's failure to do so shall be a
material breach of this Lease. Lessor shall not be required to keep the Deposit
separate from its general accounts. If Lessee performs all of Lessee's
obligations hereunder, the Deposit, or so much thereof as has not theretofore
been applied by Lessor, shall be returned without payment of interest for its
use, to Lessee (or, at Lessor's option, to the last approved assignee, if any,
of Lessee's interest hereunder) at the expiration of the term hereof, and after
Lessee has vacated the Premises. No trust relationship is created herein between
Lessor and Lessee with respect to the Deposit.

34.  Waiver. The waiver by either party of any agreement, condition or provision
herein contained shall not be deemed to be a waiver of any subsequent breach of
the same or any other agreement, condition or provision herein contained, nor
shall any custom or practice which may grow up between the parties in the
administration of the terms hereof be construed to waive or to lessen the right
of either party to insist upon performance in strict accordance with said terms.
The subsequent acceptance of rental hereunder by Lessor shall not be deemed to
be a waiver of any preceding breach by Lessee of any agreement, condition or
provision of this Lease other than the failure of Lessee to pay the particular
rental so accepted, regardless of Lessor's knowledge of such preceding breach at
the time of acceptance of such rental.

35.  Notices. All notices, consents, and demands given by either party to the
other hereunder shall be in writing and shall be deemed to have been fully given
when personally delivered (which shall be deemed to include, without limitation
delivery by means of overnight courier service) or deposited in the United
States mail, certified or registered, postage prepaid, and addressed as follows:
to Lessee at the Premises, or to such other place as Lessee may from time to
time designate in a written notice to Lessor; to Lessor at Birmingham Builders,
Inc., 1475 Folsom Street, Suite 400, San Francisco, CA 94103, or to such other
place as Lessor may from time to time designate in a written notice to Lessee.

36.  Complete Agreement. There are no oral agreements between Lessor and Lessee
affecting this Lease and this Lease supersedes and cancels any and all previous
negotiations, arrangements, brochures, agreements and understandings, if any,
between Lessor and Lessee or displayed by Lessor to Lessee with respect to the
subject matter of this Lease or the Building. There are no representations
between Lessor and Lessee other than those contained in this Lease and all
reliance with respect to any representations is solely upon such
representations.

37.  Corporate Authority. The persons executing this Lease on behalf of Lessee
do hereby covenant and warrant that Lessee is a duly authorized and existing
corporation, has and is qualified to do business in California, that such
corporation has full right and authority to enter into this Lease, and that each
and both of the persons signing on behalf of such corporation were authorized to
do so.

38.  Miscellaneous. The words "Lessor" and "Lessee" as used herein shall include
the plural as well as the singular. If there be more than one Lessee, the
obligations hereunder imposed upon Lessee shall be joint and several. Time is of
the essence of this Lease and each and all of its provisions. Submission of this
instrument for examination of signature by Lessee does not constitute a
reservation of or option for lease, and it is not effective as a lease or
otherwise until execution and delivery by both Lessor and Lessee. The
agreements, conditions and provisions

                                      -19-

herein contained shall, subject to the provisions as to assignment, apply to and
bind the heirs, executors, administrators, successors and assigns of the parties
hereto. If any provision of this Lease shall be determined to be illegal or
unenforceable, such determination shall not affect any other provision of this
Lease and all such other provisions shall remain in full force and effect. This
Lease shall be governed by and construed pursuant to the laws of the State of
California. No amendments or modifications of this Lease or any agreements in
connection therewith shall be valid unless in writing and duly executed by the
party to be charged therewith.

39. Limitation of Liability. The liability of Lessor under this Lease shall be
and is hereby limited to Lessor's interest in the Building, and no other assets
of Lessor shall be affected by reason of any liability which Lessor may have to
Lessee or to any other person by reason of this Lease.

40.  Option to Extend Lease. Provided that Lessee has not been in default under
any of the provisions of this Lease beyond any cure period specified herein and
is not in default hereunder at the time it exercises this option, Lessee shall
have one (1) option to extend the term of this Lease for an additional term of
five (5) years (the "extended term") following the expiration of this Lease,
upon all of the same terms and conditions as this Lease, provided that such
option shall be exercised by written notice to Lessor not more than twelve (12)
months nor less than nine (9) months prior to expiration of the original term of
this Lease. The rent for the extended term shall be 100% of the fair market
rental for the Premises, taking into account any concessions to tenants of
comparable size and credit in buildings of similar age and quality in the
immediate submarket. Within thirty (30) days following the date Lessee exercises
its option, Lessor and Lessee shall use their reasonable best efforts to agree
on the rent for the extended term. If Lessor and Lessee are unable to agree on
the rent for the extended term within said thirty (30) day period, then within
ten (10) days after said period, Lessor and Lessee shall each submit to the
other in writing their good faith estimate of the rent for the extended term. If
the higher of said estimates is not more than one hundred ten percent (110%) of
the lower of such estimates, the rent for the extended term shall be the average
thereof. If otherwise, then within five (5) days after submission of said
estimates, either party may submit the question to appraisal in accordance with
the following procedure. Within twenty (20) days after either party requests
appraisal, the parties shall select a mutually acceptable commercial real estate
broker with experience in the leasing of comparable space in the vicinity of the
premises, who shall determine the rent for the extended term. If the parties
cannot agree on such a commercial real estate broker within said twenty (20) day
period, then within five (5) days thereafter, each party shall select an
independent commercial real estate broker meeting the criteria set forth above.
If one party shall fail to make such appointment within said five (5) day
period, then the broker chosen by the other party shall determine the rent for
the extended term. Within twenty (20) days thereafter, each such broker shall
independently determine his or her opinion of the rent for the extended term,
and shall provide a report to Lessor and Lessee stating the basis for such
opinion. If Lessor and Lessee cannot agree upon the rent for the extended term
within twenty (20) days thereafter, the two brokers shall within such twenty
(20) day period select a third commercial real estate broker meeting the above
criteria and the third broker shall select the rent for the extended term
determined by one of the two brokers. If the two brokers selected by Lessor and
Lessee cannot agree on the third broker, the third broker shall be selected by
Lessor and Lessee within five (5) days after the expiration of said twenty (20)
day period. If Lessor and Lessee cannot agree on the third broker, the third
broker shall be selected by the then presiding judge of the

                                      -20-

Superior Court of California in and for the City and County of San Francisco. If
the foregoing process does not result in the selection of a third broker, the
parties shall equally share the costs associated with the selection process. The
amount selected in accordance with this paragraph shall be deemed to be the rent
for the extended term and such determination shall be final and binding on both
Lessor and Lessee. The cost of the appraisal shall be borne by the nonprevailing
party, as determined by the third broker. In no event shall the rent for the
extended term be less than the rent in effect during the last month of the
original term of this Lease.

41.  Brokerage Commissions. Lessee and Lessor each represents and warrants to
the other that it has dealt with no broker, agent or other person in connection
with this transaction and that no broker, agent or other person brought about
this transaction other than Colliers International, and Lessee and Lessor each
agrees to indemnify and hold the other harmless from and against any claims by
any other broker, agent or other person claiming a commission or other form of
compensation by virtue of having dealt with the indemnifying party with regard
to this leasing transaction. The provisions of this paragraph shall survive the
termination of this Lease. Any broker's fee or commission payable to Colliers
International in connection with this Lease shall be paid by Lessor pursuant to
a separate agreement.

42. Lessee's Grant to Lessor of Option to Purchase Stock of Lessee. In
consideration of Lessor's agreement to enter into this Lease, Lessee hereby
irrevocably grants to Lessor the option to purchase any number of shares of the
common stock of Lessee, in a quantity not to exceed fifty thousand (50,000)
shares, at the price of $3.25 per share. Lessor shall exercise this option by
giving Lessee written notice of such exercise at any time within three years of
Lessee's initial public offering ("IPO"). Upon receipt of such notice and tender
of the purchase price for the shares to be acquired by Lessor, Lessee shall take
all actions necessary to effect the prompt transfer of such shares to Lessor.
Within thirty (30) days after execution of this Lease by Lessor and Lessee, the
parties shall enter into a written agreement (in a form substantially similar to
that previously used by Lessee for grants to third parties (including Lessee's
employees) of options to purchase Lessee's stock) setting forth additional terms
and conditions relating to the option hereby granted. Such agreements shall
contain commercially reasonable anti-dilution provisions. The parties agree to
use their best, good-faith efforts to agree upon the terms and conditions of
such agreement. In the event that the parties are unable to agree upon the terms
and conditions of such agreement, the matter shall be resolved by way of binding
arbitration conducted under the auspices of Judicial Arbitration and Mediation
Services of San Francisco, California, with the award of the arbitrator in such
arbitration to be rendered by no later than ninety (90) days after execution of
this Lease by Lessor and Lessee. In the event either party fails to comply with
the award of the arbitrator, such award shall be confirmed in the Superior Court
of the State of California for the City and County of San Francisco. In addition
to the foregoing, at the time of the IPO Lessor shall have the right to purchase
the greater of one hundred thousand (100,000) shares or one percent (1.0%) of
the number of shares offered, at the initial offering price.

                                      -21-

     IN WITNESS WHEREOF, the parties have executed this Lease on the respective
dates indicated below:
