                             SECURED PROMISSORY NOTE

$629,672.09                                                 Berkeley, California
                                                            June 30, 2000

         1. OBLIGATION. Howard B. Urnovitz (the "OBLIGOR"), for value received,
hereby promises to pay to the order of Calypte Biomedical Corporation (the
"PAYEE"), on December 31, 2000, in lawful money of the United States of America
at the address of the Payee set forth below, (a) the principal sum of Six
Hundred Twenty-Nine Thousand Six Hundred Seventy-Two Dollars and Nine Cents
($629,672.09), which principal sum includes (i) Five Hundred Twenty-Five
Thousand Seven Hundred Seventy-Seven Dollars and Fifty-Five Cents ($525,777.55)
as the principal amount, as agreed by the Obligor and Payee hereby to have been
due as of the issuance date thereof, notwithstanding any other figure therein to
the contrary, under Obligor's Secured Promissory Note to the Payee dated
November 13, 1998 (the "1998 NOTE"), plus (ii) One Hundred Three Thousand Eight
Hundred Ninety-Four Dollars and Fifty-Four Cents ($103,894.54) of interest on
the 1998 Note accrued to date, none of which principal or interest has been paid
to the date hereof, together with (b) interest on the unpaid principal hereof
from the date hereof until paid in full, at an annual rate equal to the Prime
Rate, as hereinafter defined. The "PRIME RATE" will mean the prime rate as
published from time to time in the WALL STREET JOURNAL. Accrued interest will be
payable on payment of principal, and will continue to accrue until all principal
and accrued interest will be paid in full. Any payment of less than the total
principal amount and all accrued interest hereunder will be credited first to
accrued but unpaid interest and the balance to principal, and interest will
cease to accrue on the amount of principal so paid. Interest will be computed on
the basis of a year of 365 days for the actual number of days elapsed. This Note
may be prepaid, in whole or in part, at any time without premium or penalty. The
Obligor will, on or before August 31, 2000, sell as much of the shares of stock
of the Payee as he owns as he lawfully can sell, having net proceeds to the
Obligor, after taxes and brokerage fees and other customary costs of sale, up to
the amount owed by the Obligor hereunder, and will pay such proceeds to the
Payee, immediately upon the Obligor's receipt thereof, as a payment hereunder to
reduce the Obligor's obligations hereunder; provided that the Obligor will not
be required to sell any shares on or before such date at a price of less than
Three Dollars and Fifty Cents ($3.50). Any such shares so sold by the Obligor
will be deemed released, upon such sale, from the security interest of the Payee
granted herein. The Obligor will be responsible for and will timely pay when due
all taxes, brokerage fees and other customary costs of sale legally required to
be paid by the Payee as a result of such sale of his shares and will hold the
Payee harmless against payment thereof.

         2. EFFECT OF THIS NOTE UPON 1998 NOTE; CERTAIN WAIVERS BY PAYEE. This
Note is being issued by the Obligor to the Payee as a replacement for the 1998
Note, and upon such issuance hereof, the 1998 Note is cancelled and of no
further force and effect. The Payee hereby waives (a) the failure of the Obligor
to timely pay the 1998 Note when due, and (b) any failure of the Obligor to
maintain the level of Collateral required thereunder, provided that such waivers
are given only for such specific failures and are not given for any other
failure of Obligor either retroactively or prospectively.

         3. GRANT OF SECURITY INTEREST IN THE COLLATERAL. To secure the prompt
and punctual payment of and performance of all obligations hereunder, the
Obligor hereby grants to the Payee a continuing security interest in and lien on
all of the Obligor's right, title and interest in all the shares of capital
stock held of record or beneficially by the Obligor, and in all options held by
the Obligor to purchase capital stock of, (a) the Payee, and (b) to the extent
any such shares are held by the Obligor from time to time prior to payment in
full of this Note by the Obligor, and if permitted by the Board of Directors of
the relevant following-named corporations, of (i) Chronix Corporation and (ii)
Pepgen Corporation, whether now owned or hereafter acquired, and all proceeds
and products thereof (collectively, the "COLLATERAL"). The Obligor agrees that
the Payee may imprint a legend on the certificates evidencing all shares of
stock that are part of the Collateral in order to properly refer to this Note
therein and the security interest of the Payee therein. Upon payment in full of
all

<PAGE>

amounts due under this Note, the Payee will remove such legends and will
promptly return to the Obligor all Collateral then held by the Payee.

     4.   CERTAIN COVENANTS OF THE OBLIGOR. The Obligor agrees and covenants
that:

          (a)  The Obligor will execute and deliver such documents, and take
such other actions, as the Payee deems necessary to create, perfect and continue
the perfection of the security interest in the Collateral contemplated hereby.
The Obligor will, as soon as possible after the date hereof, deliver to the
Payee, to the attention of its Chief Executive Officer, to hold as Collateral
pursuant to this Note, all shares of stock of the Company, and, to the extent
then held by the Obligor, of Chronix Corporation and Pepgen Corporation held by
the Obligor.

          (b)  The Obligor will pay all expenses, including attorneys fees,
reasonably incurred by the Payee in the preservation, realization, enforcement
or exercise of any of the Payee's rights under this Note.

          (c)  If while this Note is outstanding the aggregate fair market value
of the Collateral is less than two hundred percent (200%) of the then-current
outstanding balance of this Note, the Obligor will, unless waived by the Payee
on a case-by-case basis in writing no more frequently than monthly, by the end
of each month in which such Collateral maintenance condition is not met, which
waiver will be entirely within the discretion of Payee, increase the Collateral
by (i) such number of shares of capital stock in the Payee, and/or of Chronix
Corporation and/or of Pepgen Corporation, to the extent that the Obligor then
holds any such shares, and/or by (ii) unexercised options to purchase shares of
capital stock of the Payee, and/or of Chronix Corporation and/or of Pepgen
Corporation, in each case to the extent that the Obligor then holds any such
unexercised options, such that the total aggregate fair market value of the
Collateral, less any exercise price for any such options, is not less than two
hundred percent (200%) of the then-outstanding balance of this Note.

     5.   EVENTS OF DEFAULT. If the Obligor fails to pay when due and payable
any principal or interest due hereunder within five (5) business days (defined
as a day when national banks in California are open for business) after the date
scheduled for payment thereof (an "EVENT OF DEFAULT") then, at the expiration of
such five-day period, or at any time thereafter, the Payee will have all rights,
privileges, powers and remedies provided by law and by this Note, which rights,
privileges, powers and remedies will be cumulative, and no single or partial
exercise of any of them will preclude the further or other exercise of the same
or any of them.

     6.   APPOINTMENT OF PAYEE AS ATTORNEY-IN-FACT. The Obligor hereby appoints
the Payee the attorney-in-fact of the Obligor to prepare, sign and file or
record, for the Obligor in the Obligor's name, any financing statements,
applications for registration and like papers and to take any other action
deemed by the Payee to be reasonably necessary or desirable in order to perfect
the security interest of the Payee hereunder in the Collateral.

                                 LEASE AGREEMENT

         LEASE AGREEMENT (this "Lease"), entered into this ___ day of June,
1998, between RYAN SOUTHBANK II, L.L.C., a Minnesota Limited Liability
Company ("Landlord"), and MINDSPRING ENTERPRISES, INC. ("Tenant").

1.       PREMISES; PERMITTED USE:

         Landlord, subject to the following terms and conditions, hereby
leases to Tenant the premises (the "Premises") at 3255 East Elwood Street,
Suite 106, Phoenix, Arizona, designated on the floor plan attached as EXHIBIT
A, comprising 40,398 square feet of area in the building located at such
address (the "Building"). Landlord has provided Tenant with the basis of the
calculation of square footages of the Premises and of the Building, which
are, respectively, 40,398 sq. ft. and 120,778 sq. ft., and which Landlord and
Tenant hereby approve for all purposes of this Lease. The Building, the
underlying land described on EXHIBIT B (the "Land") and all improvements
thereon are referred to as the "Property".

         The Premises shall be used by Tenant for general office purposes,
and for no other purpose. Tenant shall conduct and permit no activities on
the Property which create the risk of release of a Hazardous Material on, in,
under or about the Property or into the environment or violation of the
Hazardous Material Laws, or otherwise expose Landlord, Tenant, or the
Property to action by any governmental authority or third parties under the
Hazardous Materials Laws, or otherwise.

         Tenant shall have the exclusive right of possession of the Premises
and the non-exclusive and reasonable use of the driveways, parking lot and
other common areas on the Property throughout the Lease Term, 24 hours each
day, subject to casualty, condemnation, force majeure or other events beyond
the control of Landlord.

2.       TERM; POSSESSION:

         The term of this Lease ("Lease Term") shall be approximately
seventy-two (72) months commencing on the eighty-fourth (84th) calendar day
after the issuance of a building permit for the Tenant Improvements (the
"Target Commencement Date"), subject to the provisions of this Paragraph 2,
and of Paragraph 27, and ending on the last day of the seventy-second (72nd)
calendar month thereafter, unless sooner terminated or extended as herein
provided.

         Notwithstanding the Target Commencement Date, the Lease Term will
commence on the tenth (10th) business day after Landlord notifies Tenant that
a certificate of occupancy (or equivalent governmental approval of
completion) has been issued for the Tenant Improvements (as defined in
Paragraph 27) by the appropriate governmental agency, at which time the
Premises will be deemed "ready for occupancy. The certificate of occupancy
(or equivalent governmental approval of completion) may contain stipulations
and conditions to be fulfilled by Landlord so long as it permits Tenant to
take possession of the Premises and to use the Premises for the purposes
contemplated by this Lease. Tenant shall take possession of the Premises no
later than thirty (30) business days after Landlord notifies Tenant that a
certificate of occupancy (or

<PAGE>

equivalent governmental approval of completion) has been issued. The Premises
shall be considered "ready for occupancy" notwithstanding that punchlist
items of a minor nature not interfering with Tenant's intended beneficial use
of the Premises exist. Landlord agrees to complete the punchlist items to
Tenant's reasonable satisfaction at Landlord's sole expense within a period
of time that is reasonable under the circumstances following the commencement
date of the Lease Term. Landlord and Tenant shall execute a written statement
specifying (a) the commencement date of the Lease Term and (b) the
termination date of the Lease Term prior to Tenant's taking possession of the
Premises.

         If the Premises are not ready for occupancy by the Tenant on the
Target Commencement Date for any reason other than Tenant's default under
this Lease, Landlord shall continue to use due diligence to complete
construction and to deliver possession of the Premises to Tenant.

         Notwithstanding any provision in this Lease to the contrary:

         (a) If the Premises are not ready for occupancy by Tenant on or
before the one hundredth (100th) calendar day after the issuance of a
building permit for the Tenant Improvements (the "Adjusted Delivery Date")
for any reason other than Tenant's default under this Lease, Tenant Delay or
force majeure, then Tenant's sole and exclusive remedy will be to receive one
(1) day of free rent for each day from the Adjusted Delivery Date until the
Premises are ready for occupancy; and

         (b) If the Premises are not ready for occupancy by Tenant on or
before the fiftieth (50th) day after the Adjusted Delivery Date for any
reason other than Tenant's default under this Lease or Tenant Delay, then
Tenant shall have the right to cancel this Lease as its sole and exclusive
remedy by notice given to Landlord on or before ten (10) days thereafter.

         The Adjusted Delivery Date shall be extended one (1) day for each
day of Tenant Delay. "Tenant Delay" shall mean any delay in Landlord's
commencement or completion of the Building or the Tenant Improvements that
occurs as the result of: (i) any request by Tenant either that Landlord
perform any work in addition to that required under the Final Plans or that
Landlord delay in the commencement or completion of the Building or the
Tenant Improvements for any reason, (ii) any change by Tenant to the Final
Plans after final approval thereof, (iii) any failure of Tenant to respond to
any request for approval required hereunder within the time period specified
for such response or, where no response time is specified, within a
reasonable period of time after the request, (iv) any delay in Landlord's
construction of the Building or the Tenant Improvements caused by Tenant's
activities in the Premises, or (v) any other act or omission of Tenant that
effectively delays commencement or completion of the Building or the Tenant
Improvements.

         Tenant shall be entitled to enter the Premises prior to commencement
of the Lease Term, without the payment of rent or any other sums under this
Lease, but subject to all other requirements and covenants of this Lease, for
the sole purpose of installing Tenant's furniture, fixtures and equipment.
Tenant shall use reasonable care in connection with such entry, and shall not
materially interfere with construction of the Tenant Improvements or other
activity of Landlord.

                                     2

3.       MONTHLY BASE RENT:

         Tenant shall pay to Landlord during the Lease Term without any
set-off, deduction, or abatement (except only as otherwise expressly provided
in this Lease) monthly base rent ("Rent") calculated at the following annual
rates and payable on the first day of each month, in advance, at the office
of Landlord at 900 Second Avenue South, Suite 700, Minneapolis, Minnesota
55402, or at such other place as may from time to time be designated by
Landlord:

         Years 1 - 3               $12.00 / sq. ft., Net of Operating Costs

         Years 4 - 6               $13.00 / sq. ft., Net of Operating Costs

         If the Lease Term commences on a day other than the first day of a
calendar month, Rent for such month shall be prorated on a daily basis, based
on the number of days in effect during such month, and paid on or before the
commencement of the Lease Term.

         Notwithstanding the foregoing, monthly base rent will be paid for
the initial six (6) months on 15,000 square feet and for the subsequent six
(6) months on 25,000 square feet. Tenant will nevertheless be responsible for
Tenant's prorata share of Operating Costs and for all other Tenant
performance under this Lease during the abatement periods. Should tenant
default in its performance under this Lease and fail to cure the default
within any grace period expressly granted to Tenant under this Lease, the
rental abatement will become null and void and Tenant shall be liable to
Landlord for immediate repayment of all sums of rent abated under this
provision without further notice or demand from Landlord.

4.       OPERATING COSTS:

         Tenant shall, for the entire Lease Term, pay to Landlord as
additional rent, without any set-off, deduction or abatement (except only as
otherwise expressly provided in this Lease), Tenant's Proportionate Share of
Operating Costs incurred by Landlord in the operation, maintenance, repair
and management of the Property. Operating Costs shall be based on a one
hundred percent (100%)-occupied building, whether or not the entire Building
is actually occupied. Tenant's Proportionate Share of Operating Costs is a
fraction whose numerator is the square footage of the Premises and whose
denominator is the square footage of the Building.

         "Operating Costs" incurred in respect to the Property are hereby
defined to include, but shall not be limited to: (i) real estate taxes and
assessments, general or special, ordinary or extraordinary, foreseen or
unforeseen, including, without limitation, ad valorum taxes, personal
property taxes, transit taxes, special or extraordinary assessments,
government levies, substitute taxes, assessments, excises, charges or fees
assessed or levied in lieu of the foregoing, and expenses and fees incurred
in protesting any of the foregoing taxes or assessments, but excluding income
taxes, franchise taxes, inheritance taxes and gift taxes; (ii) insurance
premiums and costs including deductibles for the all-risk property and
casualty insurance that Landlord maintains under this Lease; (iii) the yearly
amortization of capital costs incurred by Landlord for improvements or
structural repairs to the Property required to comply with any laws, rules or
regulations of any governmental authority having jurisdiction over the
Property which are

                                     3

<PAGE>

enacted after the commencement date of this Lease, or with any changes in
laws, rules or regulations of any governmental authority having jurisdiction
over the Property which existed on the commencement date of this Lease, but
which changes were enacted or come into effect after the commencement date of
this Lease, or the application of either, or for the purposes of reducing
Operating Costs, which shall be amortized over the useful life of such
improvements or repairs, as reasonably estimated by Landlord; (iv) costs of
maintenance, repair, and replacement of the parking lot and driveways
(including periodic resurfacing as needed), sidewalks, loading docks (if
any), exterior light fixtures, landscaping, common signage, other common
areas and elements, and regular painting of the exterior of the Building; (v)
routine service and maintenance of the roof (including reasonable preventive
care but excluding structural repairs/replacements); (vi) costs of
electricity, water and other utilities for the common areas; (vii)
competitively priced management fees charged by Landlord, an affiliate of
Landlord or any other entity managing the Property or any part thereof;
(viii) reasonable reserves for Operating Costs; (ix) assessments, charges,
and fees levied, assessed or imposed against the Property or any part thereof
under any CC&RS or any property owner association or authority; (x) wages,
salaries and compensation of employees, consulting, accounting, legal,
maintenance and other services; and (x) any other reasonable cost, charge, or
expense which under generally accepted accounting principles would be
regarded as a maintenance and operating expense of the Property.

         In no event (except only as provided in the preceding subparagraph
or in Paragraph 8) will Operating Costs include, nor will Tenant be obligated
to pay for, (A) STRUCTURAL improvements, alterations or expenditures; (B)
depreciation; (C) Landlord's overhead; (D) repairs, alterations, additions,
improvements or replacements made to rectify or correct any defect in the
design, materials or workmanship of the Building or the Property (unless
caused by Tenant) or to comply with any requirements of any governmental
authority; (E) damage and repairs attributable to fire or other casualty; (F)
damage and repairs paid for under any insurance policy carried by Landlord in
connection with the Property; (G) costs incurred due to violation by Landlord
of the terms and conditions of this Lease; (H) legal fees, brokerage
commissions, advertising costs or other related expenses incurred in
connection with leasing; (I) accountants' fees; (J) sculptures or artwork;
(K) fees and costs incurred in connection with the defense of Landlord's
title or interest in the Property or the Building or any part thereof; (L)
rent and other costs payable under any ground lease; and (M) principal,
interest and other amounts paid pursuant to any loan secured by the Property
or the Building or any part thereof.

         As soon as reasonably practicable prior to the commencement of each
calendar year during the Lease Term, Landlord shall furnish to Tenant an
estimate of Tenant's Proportionate Share of Operating Costs for the ensuing
calendar year and Tenant shall pay, as additional rent hereunder together
with each installment of Rent, one-twelfth (1/12th) of its estimated annual
share of such Operating Costs. Attached as EXHIBIT C is Landlord's estimate
of Operating Costs for the period indicated, which is subject to adjustment
hereafter, and which Tenant shall pay, as additional rent hereunder together
with each installment of rent, one-twelfth (1/12th) of its share of such
estimated Operating Costs. As soon as reasonably practicable (but in no event
later than ninety (90) days) after the end of each calendar year during the
Lease Term, Landlord shall furnish to Tenant a statement of the actual
Operating Costs for the previous calendar year, including Tenant's share of
such amount, and within thirty (30) days thereafter Tenant shall pay to
Landlord, or Landlord to Tenant, as the case may be, the difference between
such actual and

                                     4

<PAGE>

estimated Operating Costs paid by Tenant. Tenant's share of such Operating
Costs for the years in which this Lease commences and terminates shall be
prorated based upon the dates of commencement and termination of the Lease
Term.

         The annual statement of actual Operating Costs shall be certified to
be correct by Landlord. Landlord shall maintain full and accurate books and
records with respect to all Operating Costs for a period of not less than one
(1) year.

         Tenant shall have the right at any time during normal business hours
and upon reasonable prior notice to Landlord to inspect and audit Landlord's
books and records with respect to Operating Costs. Tenant shall not have the
right, however, to inspect and audit Landlord's books and records with
respect to the Operating Costs of any given year following the first (1st)
anniversary of Tenant's receipt of the statement of the actual Operating
Costs for the year in question.

5.       ADDITIONAL TAXES:

         Tenant shall pay as additional rent to Landlord, together with each
installment of Rent, Tenant's Proportionate Share of Operating Costs and any
other payment made by Tenant under this Lease, the amount of any gross
receipts tax, transaction privilege or sales tax or similar tax (but
excluding therefrom any income tax) payable, or which will be payable, by
Landlord, by reason of the receipt of the Rent, Tenant's share of Operating
Costs and any other payment made by Tenant under this Lease, and adjustments
thereto.

6.       ASSIGNMENT, SUBLETTING:

         Except for an assignment or subletting to a parent, an affiliate or
a wholly owned subsidiary of Tenant (any such entity is referred to herein as
a "Tenant Affiliate"), Tenant may not assign this Lease, or sublet all or any
part of the Premises, without the Landlord's prior written consent, which
consent shall not be unreasonably withheld, or delayed. Notwithstanding the
foregoing, it shall be a condition to any assignment or subletting
(including, without limitation, one to a Tenant Affiliate) that the assignee
or sublessee shall assume in writing the obligations of Tenant under this
Lease, and such assignment or subletting shall not relieve Tenant of its
obligations to Landlord under this Lease.

7.       UTILITIES:

         Landlord shall provide mains and conduits to supply phone, water,
electricity (including main panel with breakers) and sanitary sewage to the
Premises. Tenant shall pay, when due, all charges for sewer usage, garbage
disposal, refuse removal, water, electricity, telephone and/or other utility
services or energy source furnished to the Premises during the Lease Term.
Tenant may separately contract for utilities with utility providers so long
as Tenant pays all associated costs and expenses.

                                     5

<PAGE>

8.       CARE AND REPAIR OF PREMISES:

         Tenant shall, at all times throughout the Lease Term, including all
renewals and extensions, and at its sole expense, keep and maintain the
Premises in good repair and in a clean, safe, orderly, sanitary and first
class condition in compliance with all applicable laws, codes, ordinances,
rules and regulations, free of any accumulation of dirt and rubbish, and
Tenant shall arrange its own trash removal. Tenant's obligations shall
include, but not be limited to, the maintenance, repair, and replacement, if
necessary, of interior lighting, HVAC, electrical and plumbing systems
(including without limitation sewer lines), fixtures and equipment,
restrooms, interior walls and ceilings, partitions, doors and windows,
regular painting of the interior, and the replacement of all broken glass
from doors and windows unless breakage is due to a defect in the design,
materials or workmanship of the Building (excluding Tenant's design errors),
to a breach of Landlord's own repair and maintenance obligations under this
Lease, or to Landlord's negligence. Tenant's responsibility in respect to the
electrical and plumbing systems is limited to system components within the
Premises and to any damage to the systems that is caused by Tenant. Tenant
shall cause to be performed by a competent service company, preventive
maintenance of the HVAC units serving the Premises as recommended by the
equipment manufacturer. When used in this provision, the term "repairs" shall
include ordinary and customary replacements or renewals when necessary, and
all repairs made by Tenant shall be equal in quality and class to the
original work.

         Tenant shall not be required to perform or pay for any structural
expenditure on the Property in order to comply with (i) any law, ordinance,
rule or regulation; or (ii) with any recommendation of Landlord's insurance
rating organization, unless the same is required as the direct result of
Tenant's particular use of the Premises (as opposed to Tenant's mere
occupancy of the Premises or Tenant's conduct of business, generally), EXCEPT
to the extent that Tenant is required to pay Tenant's Proportionate Share of
amortized capital expenditures under Paragraph 4.

         If Tenant fails, refuses or neglects to maintain or repair the
Premises and the Property as required in this Lease for ten (10) days after
notice shall have been given Tenant, Landlord may make such repairs without
liability to Tenant for any loss or damage that may accrue to Tenant's
merchandise, fixtures or other property or to Tenant's business by reason
thereof (except that Landlord shall be liable for its own negligence or
willful misconduct), and upon completion thereof, Tenant shall pay to
Landlord all competitively priced costs plus eight percent (8%) for overhead
incurred by Landlord in making such repairs within ten (10) days after Tenant
receives from Landlord the bill therefor.

         Landlord shall be responsible for maintenance, repair and
replacement of the parking lot, driveways, sidewalks, loading docks (if any),
exterior light fixtures, landscaping, and other common areas located on the
Property, the structural elements of the roof and shall keep the foundation
(concrete slab floor), exterior walls, and all other structural portions of
the Property and the Building (not otherwise designated to be maintained and
repaired by Tenant) in good repair and in a clean, safe, sanitary and first
class condition and in compliance with all applicable laws, codes,
ordinances, rules and regulations, and if necessary or required by proper
governmental authority, make modifications or replacements thereof, except
that Landlord shall

                                     6

<PAGE>

not be required to make any such repairs, modifications or replacements which
become necessary or desirable by reason of the negligence or willful
misconduct of Tenant, its agents, servants or employees, by reason of anyone
illegally entering or upon the Premises, which repairs, modifications or
replacements shall be made by Tenant at its sole expense. Landlord shall also
remedy, at Landlord's sole expense, any latent defects in the Premises
existing at the beginning of the Lease Term as well as damage to the Premises
caused by the willful act or negligence of Landlord or its agents; Landlord
shall also repair any defects or failures in building systems to the extent
the same were not constructed in accordance with the terms of this Lease or
applicable law. Notwithstanding the foregoing, Landlord shall have no
liability under this paragraph for any repair, maintenance or replacement
required because of Tenant's own design error, and nothing in this paragraph
will alter Tenant's obligation to pay Operating Costs to Landlord under
Paragraph 4 even though this paragraph may impose on Landlord the obligation
of performing the necessary maintenance, repair or replacement.

9.       COVENANTS OF TENANT:

         Tenant agrees that it shall:

         (a) Observe (i) such reasonable and customary rules and regulations
as from time to time may be put in effect by Landlord, provided that Tenant
has received reasonable prior notice of the same, for the general safety of
Landlord and the occupants of the Building and for the integrity and
reputation of the Property; and (ii) the restrictions and requirements of
CC&RS now or hereafter applicable to the Property or any portion thereof.

         (b) Give Landlord access to the Premises at all reasonable times,
and upon reasonable prior notice (but not less than one (1) business day,
except in case of emergency) from Landlord, without change or diminution of
rent so long as Landlord complies with the terms of this Lease, to enable
Landlord to examine the same and to make such repairs, additions and
alterations as Landlord is entitled or required to make under the terms of
this Lease, and to exhibit the Premises to prospective purchaser of the
Property or lenders thereon; and during the one hundred twenty (120) days
prior to the expiration of the term, to exhibit the Premises to prospective
tenants. Landlord may place upon the Building any "For Sale" and "For Lease"
signs. Landlord will schedule such entries with Tenant and will use
reasonable efforts to minimize disruption of Tenant's business caused by such
entry and Landlord will comply with Tenant's reasonable security procedures
in connection with such entry. Tenant will have the right to be present
whenever Landlord comes on the Premises under this paragraph.

         (c) Upon the expiration or earlier termination of this Lease in any
manner whatsoever, excepting only termination because of Tenant's default
under this Lease (unless Landlord elects the contrary in writing), remove
Tenant's furniture, fixtures and equipment, generators, computers, telephones
and switches, and telecommunications equipment (to the extent the same was
installed by Tenant) and Tenant's other goods, inventory and effects and
those of any other person claiming under Tenant, and quit and deliver the
Premises and the Property to Landlord peaceably and quietly in as good order
and condition as the same are now in or hereafter may be put in by Landlord
or Tenant, reasonable use and wear thereof, and repairs which are Landlord's
obligation, excepted. Furniture, fixtures, equipment, and all other property

                                     7

<PAGE>

not removed by Tenant at the termination of this Lease shall be considered
abandoned, and Landlord may dispose of the same as it deems expedient.

         (d) Not place signs on or about the Premises or the Property without
first obtaining Landlord's written consent thereto, which consent will not be
unreasonably withheld or delayed. All signs must comply with applicable laws,
ordinances, and regulations, all CC&RS and Landlord's reasonable sign
criteria. Tenant shall have "major tenant" status for signage purposes under
the Southbank Comprehensive Sign Program dated June 30, 1988, and if
authorization of the governing body under the Southbank Comprehensive Sign
Program is required, Landlord will make every reasonable effort to obtain
such authorization for Tenant, such that Tenant will have three exterior
signs on the building facing each of the three major roadways, which are
University Drive, Ellwood Street, and Interstate 10. Landlord agrees that
placement of these three signs is acceptable under Landlord's sign criteria
EXHIBIT D sets forth "major tenant" criteria and associated signage rights.

         (e) Not overload, damage or deface the Premises or do any act which
may make void or voidable any insurance on the Premises or the Building, or
which may render an increased or extra premium payable for insurance.

         (f) Not make any alterations or additions to the Property the cost
of which would exceed $10,000.00 without obtaining the prior written approval
of the Landlord, which shall not be unreasonably withheld or delayed. All
alterations, additions or improvements (including carpeting or other floor
covering which has been glued or otherwise affixed to the floor) which may be
made by Landlord upon the Property, except movable office furniture,
equipment and generators, computers, telephone and telecommunication systems,
shall be the property of Landlord, and shall remain upon and be surrendered
with the Premises, as a part thereof, at the termination of this Lease.

         (g) Keep the Premises and the Property free from any mechanics',
materialmen's, contractors' or other liens arising from, or any claims for
damages growing out of, any work performed, materials furnished or
obligations incurred by or on behalf of Tenant. Provided, however, that
Tenant shall have the right to contest any such lien, in which event such
lien shall not be considered a default under this Lease until the existence
of the lien has been finally adjudicated and all appeal periods have expired.
Tenant shall indemnify, defend, and hold harmless Landlord for, from and
against any such lien, or claim or action thereon, reimburse Landlord within
ten (10) business days after demand therefor by Landlord for costs of suit
and reasonable attorneys' fees incurred by Landlord in connection with any
such lien, claim or action, and, upon written request of Landlord, provide
Landlord with a bond in an amount and under circumstances necessary to obtain
a release of the Premises or the Property from such lien. Notwithstanding the
foregoing, Tenant will have no responsibility for the liens of contractors or
others hired exclusively by and for Landlord.

         (h) Indemnify, defend and hold Landlord harmless for, from and
against all claims, obligations, liabilities, costs, expenses and reasonable
attorneys' fees and court costs which Landlord may suffer or incur by reason
of Tenant's breach of this Lease, or by reason of the negligence or willful
misconduct of Tenant or its employees, agents, invitees or licensees on or

                                     8

<PAGE>

about the Premises or the Property. Tenant shall comply with all applicable
laws, regulations, ordinances and other legal requirements in connection with
its use and occupancy of the Premises.

10.      PARKING AND DRIVES:

         Subject to the refinements, if any, in Paragraph 26 of the Rider to
this Lease, Tenant, its employees, and invitees shall have the non-exclusive
right to use the common driveways and parking lots with the other tenants and
customers of the Building. The use of such driveways and parking facilities
is subject to such reasonable rules and regulations as Landlord may impose.
Tenant further agrees not to use, or permit the use by employees, the
driveways, parking or truck-loading areas for the overnight or any other
storage, or for the maintenance or repair or cleaning, of automobiles or
other vehicles without the written permission of Landlord. Tenant shall not
place or store goods, materials, supplies, equipment, automobiles or other
vehicles or other property of Tenant in the common areas, common driveways or
parking lots or anywhere else in the Project or in the Building, excepting
wholly with the Premises.

11.      CASUALTY LOSS:

         Subject to the qualifications in this Paragraph 11, in case of
damage to the Premises or the Building by fire or other casualty, Tenant
shall give immediate notice to Landlord, who shall then cause the damage
(including any damage to the Tenant Improvements) to be repaired with
reasonable speed, at the expense of the Landlord, subject to reasonable
delays caused by force majeure events and other similar delays beyond the
reasonable control of Landlord. Rent and other charges payable by Tenant
hereunder shall abate proportionately during any period in which, by reason
of such casualty, Tenant reasonably determines that there is substantial
interference with the operation of Tenant's business in the Premises. Such
abatement shall continue for the period commencing with the date of such
damage or destruction and ending with the date that business may be fully
resumed on the Premises, as reasonably determined by Tenant. In the event
such damage results solely from the act, fault or neglect of Tenant, Tenant's
employees or agents, there shall be no abatement of rent.

         In the event the cost to repair the damage shall exceed twenty-five
percent (25%) of the full replacement value of the Building, or if the damage
shall be so extensive that repairs cannot be completed within ninety (90)
days from the date of issuance of required permits (permitting to take no
more than 60 days and Landlord to use diligent efforts to obtain same), then
Landlord shall have the right to terminate this Lease, as of the date of such
damage, by notice given to Tenant within thirty (30) days following the
casualty loss. If this Lease is terminated, Rent and Operating Costs shall be
adjusted to the date of such damage and Tenant shall vacate the Premises.

         Tenant hereby waives any statutory right to terminate this Lease or
to have a reduction of rent in the event of casualty loss or destruction, the
rights of tenant in such instance to be determined by this Paragraph 11.
Notwithstanding the foregoing two paragraphs, Landlord shall have no
obligation to repair or rebuild the Premises or any portion of the Building
unless Landlord has received sufficient insurance proceeds for that purpose,
free of any claim by any

                                     9

<PAGE>

lender on the Property, or if the casualty loss occurs in the last eighteen
(18) months of the Lease Term.

12.      CONDEMNATION:

         If all or a portion or the Premises or the Property is taken by
eminent domain or transferred under threat of such taking, this Lease shall
automatically terminate as of the date of taking only with respect to the
portion of the Premises or Property so taken. If a portion of the Premises or
the Property is taken by eminent domain such that the Premises are no longer
suitable for Tenant's intended use, in Tenant's reasonable discretion, Tenant
shall have the right to terminate this Lease as of the date of taking by
giving written notice thereof to Landlord within ten (10) days after such
date of taking. If Tenant does not elect to terminate this Lease, Landlord
shall, at its expense, promptly restore the Premises and the Property
(including the Tenant Improvements), exclusive of any improvements or other
changes made by Tenant, to as near the condition which existed immediately
prior to the date of taking as reasonably possible, and the rent and other
charges payable under this Lease shall abate in the same manner as described
in Paragraph 11.

         All damages awarded for a taking of the Property under the power of
eminent domain shall belong to and be the exclusive property of Landlord,
whether such damages be awarded as compensation for diminution in value of
the leasehold estate hereby created or to the fee of the Property; provided,
however, that Landlord shall not be entitled to any separate award made to
Tenant for the value and cost of Tenant's personal property, fixtures and
moving expenses.

13.      MUTUAL RELEASE/WAIVER OF SUBROGATION; INSURANCE:

         Landlord and Tenant each hereby release the other from any and all
liability or responsibility for any direct or consequential loss, injury or
damage during the Lease Term, to the extent such loss, injury or damage is
covered by the terms of any insurance policy maintained by Landlord or
Tenant. Inasmuch as the above mutual waivers will preclude the assignment of
any claim by way of subrogation (or otherwise) to an insurance company (or
any other person), each party hereto agrees if required by such policies to
give to each insurance company which has issued to it all risk and other
property insurance, written notice of the terms of said mutual waivers, and
to have such policies properly endorsed, if necessary, to prevent the
invalidation of said insurance coverage by reason of the waivers.

         Tenant shall not do anything in or about the Premises or the
Property which will increase insurance rates on the Premises or the Property.
If Landlord shall consent to such use, Tenant agrees to pay as additional
rental any increase in premiums for all risk insurance resulting from the
business carried on in the Premises by Tenant. Tenant shall, at its own
expense, comply with the requirements of insurance underwriters and insurance
rating bureaus and governmental authorities having jurisdiction, except to
the extent this Lease requires Landlord to comply with the same.

         Tenant shall maintain in full force and effect during the term
hereof, a policy of public liability insurance under which Landlord and
Tenant shall be named insureds. The minimum

                                     10

<PAGE>

limits of liability of such insurance shall be $2,000,000.00 combined single
limit as to bodily injury and property damage. Tenant shall also carry at its
own cost business interruption insurance with coverage and terms that are
commercially reasonable.

         Tenant may provide any coverage required under this Lease through
blanket policies.

         Landlord shall, during the Lease Term, maintain the following
insurance:

         (a) Property insurance insuring the Building and the Premises
(including all installations and fixtures) but excluding Tenant's personal
property) against loss or damage due to the perils of fire and other
casualties covered within the classification of fire and extended coverage,
vandalism, malicious mischief, special extended coverage (All Risk),
sprinkler leakage and water damage. Such policies shall provide for loss
payable to Landlord. Such policies shall include coverage equal to the full
replacement cost of the Building, including the Premises (replacement cost
new, including coverage for the cost of debris removal and coverage for the
cost of complying with building, zoning, safety, land use and other laws as a
result of any casualty or loss) as to prevent the application of co-insurance
provisions. Such policies may include rent loss and difference-in-conditions
coverage.

         Property insurance required to be carried by Landlord hereunder
shall be obtained from companies maintaining at the commencement of the
policy term a "General Policyholders Rating" of at least B+ and a financial
rating of at least Class, as set forth in the most current issue of "Best's
Insurance Guide."

         The party with a duty to maintain insurance hereunder (the "Insured
Party") agrees to deliver to the other party certificates of insurance
evidencing such coverage. Each policy shall contain a provision requiring
thirty (30) days' written notice to both parties before cancellation of the
policy can be effected. The Insured Party shall provide the other party, at
least fifteen (15) days prior to the expiration of such policies, with
evidence of renewals or "insurance binders" evidencing renewal thereof.

14.      HAZARDOUS MATERIALS:

         (a) As used in this Lease, the term "Hazardous Material" means any
explosives, radioactive materials, or substances defined as or included in
the definition of "hazardous substances", "hazardous wastes", "infectious
wastes", "hazardous materials" or "toxic substances" now or subsequently
regulated under any past, present, or future federal, state or local laws or
regulations or ordinances ("Hazardous Materials Laws") including, without
limitation, oil, petroleum-based products, medical wastes, paints, solvents,
lead, mercury, cyanide, DDT, acids, pesticides, asbestos, radon, PCBs,
similar compounds, and other contaminants.

         (b) Excepting the reasonable and prudent use of materials essential
to the processes in Tenant's operations, and the incidental storage thereof,
which shall be in full compliance with all Hazardous Material Laws, Tenant
shall not cause or permit any Hazardous Material to be generated, produced,
brought upon, used, stored, treated, discharged, released, spilled or
disposed

                                     11

<PAGE>

of on, in, under or about the Premises or the Property, or into the
groundwater or the environment, by Tenant, its affiliates, sublessees,
assignees, or the employees, agents, invitees, licensees, contractors or
representatives of any of the foregoing. Tenant shall conduct no business on
the Premises or the Property whose primary purpose is the generation,
production, use, storage, treatment, disposal, sale, conveyance or transfer
of any Hazardous Material. The use of any Hazardous Material on the Premises
or the Property shall be a secondary function incidental to Tenant's
business. Tenant shall not cause or permit any above-ground or underground
storage tank or container to be located on, in, under or about the Premises
or the Property without Landlord's prior written consent, full compliance
with all Hazardous Materials Laws, and adherence to all other reasonable
requirements of Landlord protecting the Premises, the Property, the
groundwater and the environment.

         (c) Tenant shall indemnify, defend and hold Landlord harmless for,
from and against all actions (including, without limitation, remedial or
enforcement actions of any kind, administrative or judicial proceedings, and
orders or judgments arising out of or resulting therefrom), costs, claims,
damages, expenses (including, without limitation, attorneys', consultants'
and experts' fees, court costs and amounts paid in settlement of any claims
or actions), fines, forfeitures or other civil, administrative or criminal
penalties, injunctive or other relief (whether or not based upon personal
injury, property damage, or contamination of, or adverse effects upon, the
environment, water tables or natural resources), liabilities or losses
arising from a breach of the provisions of this Paragraph 14, or from any
release of a Hazardous Material on, in, under or about the Property, or into
the groundwater or the environment, by Tenant, its affiliates, sublessees,
assignees, or the employees, agents, invitees, licensees, contractors or
representatives of any of the foregoing.

         (d) In the event that Hazardous Materials are discovered upon, in,
or under the Property, and any governmental agency or entity having
jurisdiction over the Property or any Hazardous Material Law requires the
removal or remediation of such Hazardous Materials, (i) Tenant shall be
responsible for removing and remediating those Hazardous Materials arising
out of or related to (x) any breach of the provisions of clause (b) above or
(y) any act or omission of Tenant, it affiliates, sublessees, assignees or
the employees, agents, invitees, licensees, contractors or representatives of
any of the foregoing on or about the Property, and (ii) Landlord shall be
responsible for removing and remediating any Hazardous Materials released on,
in, under or about the Property by Landlord or Landlord's employees, agents,
invitees, licensees, contractors or representatives, at Landlord's expense.
Notwithstanding the foregoing, Tenant shall not take any remedial action in
or about the Premises or the Property without first notifying Landlord of
Tenant's intention to do so and affording Landlord the opportunity to protect
Landlord's interest with respect thereto.

         (e) Tenant immediately shall notify Landlord in writing of: (i) any
spill, release, discharge or disposal of any Hazardous Material in, on or
under the Premises, the Property or any portion thereof; (ii) any
enforcement, cleanup, removal or other governmental or regulatory action
instituted, contemplated, or threatened (if Tenant has notice thereof)
pursuant to any Hazardous Materials Laws; (iii) any claim made or threatened
by any person against Tenant, the Premises, or the Property relating to
damage, contribution, cost recovery, compensation, loss or injury resulting
from or claimed to result from any Hazardous Materials; and (iv) any reports

                                     12

<PAGE>

made to any governmental agency or entity arising out of or in connection
with any Hazardous Materials in, on, under or about or removed from the
Premises or the Property, including any complaints, notices, warnings,
reports or asserted violations in connection therewith. Tenant also shall
supply to Landlord as promptly as possible, and in any event within five (5)
business days after Tenant first receives or sends the same, copies of all
claims, reports, complaints, notices, warnings or asserted violations
relating in any way to the Premises, the Property or Tenant's use or
occupancy thereof.

         (f) Without limiting the foregoing indemnity, Tenant shall be
responsible to pay for, or reimburse Landlord for, the cost of any
investigations, studies, cleanup or corrective action initiated or undertaken
on account of any action or inaction of Tenant in violation of any Hazardous
Materials Laws at or affecting the Premises and/or Property, or by reason of
any other act or omission of Tenant in breach of this Lease.

         (g) Tenant will provide Landlord with a copy of any environmental
audit, study or report concerning the Property or any part thereof within the
possession or control of Tenant.

         (h) Landlord represents and warrants to Tenant that the Premises
contains no Hazardous Materials (including, without limitation, asbestos) as
a result of Landlord's development of the Property, excepting insubstantial
amounts thereof, if any, in quantities not having materially adverse effects
on the environment or upon the health and safety of persons. Landlord is
making no representation or warranty to Tenant in respect to the Land other
than the assurance that Landlord has not discharged, released, spilled or
disposed of a Hazardous Material on, in, under or about the Land.

         (i) The respective rights and obligations of Landlord and Tenant
under this Paragraph 14 shall survive the expiration or termination of this
Lease or Tenant's non-occupancy of the Premises.

15.      DEFAULT; WAIVER OF TRIAL BY JURY:

         In the event Tenant fails to perform any of the terms or conditions
hereof (but excluding the payment of rental or other monetary sums due under
this Lease) and such failure continues for thirty (30) days after written
notice of default from Landlord, provided, however, that if such failure
cannot reasonably be corrected, even by prompt and diligent action, within
thirty (30) days, and if Tenant commences curing such failure within such
30-day period and thereafter diligently pursues the cure to completion,
Tenant shall have a reasonable period of time after the thirtieth (30th) day
to continue curing, or in the event Tenant fails to pay any rental or other
sum of money due hereunder and such failure continues for ten (10) days after
notice thereof to Tenant, time being declared to be of the essence, and no
further notice of default being required, Landlord may resort to any and all
legal remedies or combination of remedies which Landlord may desire to assert
including but not limited to one or more of the following: (1) re-enter the
Premises in the manner provided by law, (2) declare this Lease at an end and
terminated, (3) sue for the rent due and to become due under the Lease, and
for any damages sustained by Landlord and (4) continue this Lease in effect
and relet the Premises on such terms and conditions as Landlord may deem
reasonably advisable with Tenant remaining liable for the monthly rent and

                                     13

<PAGE>

all other sums payable under this Lease, plus the reasonable cost of
obtaining possession of the Premises and of reletting the Premises, including
broker's commissions, and of any repairs and alterations necessary to prepare
the Premises for reletting, less the rentals actually received from such
reletting, if any. Landlord shall use reasonable efforts to mitigate damages
and relet the Premises. Any recovery of future rent from Tenant, will be
discounted by applying the Federal Reserve rate of the Federal Reserve Bank
in San Francisco at the time of award, plus one percent (1%).

         No action of Landlord shall be construed as an election to terminate
the Lease or to accept a surrender of the Premises unless written notice of
such intention be given to Tenant. Tenant agrees to pay as additional rental
all reasonable attorneys' fees and other costs and expenses incurred by
Landlord in enforcing any of Tenant's obligations under this Lease. The
mention in this Lease of any remedies shall not be deemed to be a waiver by
Landlord of any other or further remedies available at law or in equity or
under other provisions of this Lease, all of which are expressly preserved
and shall be available to Landlord including, without limitation, Landlord's
statutory lien rights.

         The prevailing party in any dispute arising under this Lease shall
be entitled to recover from the other party all reasonable attorneys' fees
and other costs and expenses incurred by the prevailing party, such fees to
be set by a court and not a jury. Any amount due from either party hereunder
which is not paid when due shall bear interest at the rate of twelve percent
(12%) per annum from the due date until paid. The mention in this Lease of
any remedies shall not be deemed to be a waiver by Tenant of any other or
further remedies available at law or in equity from time to time, all of
which are expressly preserved and shall be available to Tenant.

         Neither acceptance of Rent by Landlord, nor acceptance of partial
payment of Rent or other partial performance, with or without knowledge of
breach, nor failure of Landlord to take action on account of any breach
hereof or to enforce its rights hereunder shall be deemed a waiver of any
breach, and absent written notice or consent, the breach shall be a
continuing one.

         If Landlord defaults under this Lease, Tenant shall give Landlord
written notice of the default and Landlord shall have (a) ten (10) days to
correct the same, if the default can be corrected by the payment of money,
and (b) thirty (30) days to correct the same, if the default cannot be
corrected by the payment of money, provided that if a non-monetary default
cannot reasonably be cured within such 30-day period, and if Landlord is
proceeding with due diligence to cure the default, Landlord will have such
additional time as may be reasonably necessary to cure the default so long as
Landlord promptly commences such cure within the 30-day period. The holder of
any mortgage or deed of trust on the Property shall have the right to cure
any default of Landlord with equal cure periods. Such lender's cure period
will begin to run upon its receipt of written notice from Tenant setting
forth the alleged default of Landlord, provided Landlord or such lender has
given Tenant written notice of the lender's address. If Landlord or its
lender fails to pay any amounts due Tenant within the applicable time period
or to otherwise cure any default of Landlord within the time period specified
above, then Tenant shall have as its sole and exclusive remedy the right to
cure any default at Landlord's expense and seek recovery of such sum from
Landlord by an action at law, except that nothing herein shall limit Tenant's

                                     14

<PAGE>

right to equitable relief (including injunction or specific performance) in
the event Landlord and its lender fail to cure within the applicable time
period.

         Tenant agrees to look solely to Landlord's interest in the Property
for the recovery of any judgment from Landlord or the payment of any
obligation, liability or claim under, arising out of, or relating to this
Lease, it being hereby agreed that, except to the extent of Landlord's
interest in the Property, Landlord, the assets of Landlord, or if Landlord is
a partnership, its partners whether general or limited, or if Landlord is a
corporation, Landlord, its directors, officers or shareholders, or if
Landlord is a limited liability company, Landlord and its members and
managers shall never be liable for any judgments, claims, obligations or
liabilities under, arising out of, or relating to this Lease.

         LANDLORD AND TENANT, EACH BEING FULLY INFORMED BY THEIR RESPECTIVE
COUNSEL OF THE LEGAL CONSEQUENCES, WAIVE THE RIGHT TO TRIAL BY JURY.

16.      NOTICES:

         All bills, statements, notices or communications which Landlord or

Any notice by Tenant to Landlord must be given in the same manner, but addressed
to Landlord at the address set forth above, or in case of subsequent change upon
notice given, to the latest address furnished.

17.      HOLDING OVER:

         Should Tenant continue to occupy the Premises after expiration of
the Lease Term with Landlord's express written consent, such tenancy shall be
from month to month (and in no event for any longer term) at a rental rate
equal to the rate in force immediately preceding expiration of the Lease
Term. If Tenant's holdover is WITHOUT Landlord's express written consent,
Landlord may re-enter and take possession of the Premises immediately and
have all other remedies set forth in this Lease, in which event Tenant shall
pay for each day of occupancy after the expiration of the Lease Term a sum
equal to one hundred fifty percent (150%) of the monthly rent for the last
month of the Lease Term, prorated on a daily basis and based upon a
thirty-day month.

18.      SUBORDINATION:

         This Lease and the rights of Tenant shall be and are subject and
subordinate at all times to the lien of any first mortgage or deed of trust
now or hereafter in force against the Property, provided, however, that (i)
in the case of any mortgage or deed of trust encumbering the Property as of
the date of this Lease, Landlord will obtain, prior to the commencement of
the Lease Term, an agreement between the beneficiary or mortgagee thereof and
Tenant that so long as no default exists hereunder and Tenant attorns to
Landlord's successor pursuant to the provisions of this Lease, no termination
of such encumbrance (or any proceeding in connection therewith) shall disturb
Tenant's possession of the Premises and this Lease shall remain in full force
and effect; and (ii) in the case of any first mortgage or deed of trust
encumbering the Property after the date hereof, the beneficiary or mortgagee
thereof agrees, either in such encumbrance or in a separate agreement with
Tenant, that so long as no default exists under this Lease and Tenant attorns
pursuant to Landlord's successor pursuant to the provisions of this Lease, no
foreclosure of such encumbrance (or any proceeding in connection therewith)
shall disturb Tenant's possession of the Premises and this Lease shall remain
in full force and effect. Tenant at any time and from time to time, upon not
less than ten (10) days' prior written notice from Landlord shall execute
such further instruments confirming the subordination of this Lease to the
lien of any such first mortgage or deed of trust as shall be requested by
Landlord.

19.      ESTOPPEL CERTIFICATE:

         Tenant shall at any time and from time to time, upon not less than
ten (10) days' prior written notice from Landlord, execute, acknowledge and
deliver to Landlord and any other parties designated by Landlord, a statement
in writing certifying (a) that this Lease is in full force and effect and is
unmodified and that Tenant has taken possession of the Premises and has
accepted and approved the condition of the Premises and the Tenant
Improvements (or, if modified, or disapproved, stating the nature of such
modification or disapproval), (b) the date to which the rental and other
charges payable hereunder have been paid in advance, if any, (c) that there
are, to Tenant's actual knowledge, no uncured defaults on the part of
Landlord hereunder (or specifying such defaults if any are claimed), and (d)
any additional statement commonly included in a reputable institutional
lender's estoppel certificate in similar transactions. Such statement may be
furnished to and relied upon by any prospective purchaser, tenant or
encumbrancer of all or any portion of the Property and shall include any
further statement that a good faith purchaser, tenant or encumbrancer would
reasonably require.

         Landlord shall at any time and from time to time, upon not less than
ten (10) days' prior written notice from Tenant, execute, acknowledge and
deliver to Tenant and any other parties designated by Tenant, a statement in
writing certifying (a) that this Lease is in full force and effect and is
unmodified (or, if modified, stating the nature of such modification), (b)
the date to which the rental and other charges payable hereunder have been
paid in advance, if any, and (c) that there are, to Landlord's actual
knowledge, no uncured defaults on the part of Tenant hereunder (or specifying
such defaults if any are claimed), and (d) any additional statement commonly
included in a reputable institutional lender's estoppel certificate in
similar transactions. Such statement may be furnished to and relied upon by
any prospective sublessee, assignee or encumbrancer of all or any portion of
Tenant's interest in the Property and shall include any further statement
that a good faith sublessee, assignee or encumbrancer would reasonably
require.

20.      SERVICE CHARGE:

         Tenant agrees to pay a service charge equal to one percent (1 %) per
month or any portion thereof of any payment of Rent payable by Tenant
hereunder which is not paid within ten (10) business days from the date due,
or of $5.00 per month or portion thereof, whichever is greater. Such service
charge shall only be assessed against Tenant if Tenant has failed to pay the
Rent within ten (10) business days of the date due more than twice in a
12-month period during the Lease Term, and Landlord has delivered to Tenant
notice of such failure more than twice in such 12-month period.

21.      BINDING EFFECT:

         The word "Tenant", wherever used in this Lease, shall be construed
to mean tenants in all cases where there is more than one tenant, and the
necessary grammatical changes required to make the provisions hereof apply to
corporations, partnerships, limited liability companies, or individuals, men
or women, shall in all cases be assumed as though in each case fully
expressed. Each provision hereof shall extend to and shall, as the case may
require, bind and inure to the

                                     17

<PAGE>

benefit of Landlord and Tenant and their respective heirs, legal
representatives, successors and assigns, provided that this Lease shall not
inure to the benefit of any heir, legal representative, transferee or
successor of Tenant except as expressly provided in this Lease.

         Landlord may assign its right, title, and interest in the Property
and under this Lease, and such assignment shall thereupon automatically
terminate Landlord's future obligations under this Lease, provided that the
assignee shall assume, in writing, the Landlord's obligations under this
Lease arising from the date of assignment.

22.      QUIET ENJOYMENT:

         So long as Tenant is not in default under this Lease (after
expiration of any applicable notice and cure periods), Tenant shall peaceably
and quietly have, hold and enjoy the Premises during the Lease Term, subject
to force majeure, casualty, condemnation and other events beyond Landlord's
reasonable control. Notwithstanding the foregoing, defects in Landlord's
title, foreclosure or other enforcement of Landlord's lender's lien shall not
be excluded from Landlord's covenant of quiet enjoyment.

23.      BROKER:

         If and when Tenant takes possession of the Premises, Landlord shall
pay a leasing commission to CB Commercial Real Estate Group, Inc., in the
amount of five percent (5.0%) for years one (1) through five (5) and three
(3.0%) for year six (6) of the rent payable hereunder. Each party hereto
represents to the other that, except for CB Commercial Real Estate Group,
Inc. (with respect to Tenant) and Lee & Associates (with respect to
Landlord), it has not authorized any broker or finder to act on its behalf in
connection with this Lease and that such party has not dealt with any broker,
agent, or finder purporting to act on behalf of any other party. Landlord
shall pay any commissions due Lee & Associates. Each party hereto agrees to
indemnify and hold harmless the other party from and against any and all
claims, losses, damages, costs, or expenses of any kind or character arising
out of or resulting from any agreement, arrangement, or understanding (except
as set forth above with respect to Agent) alleged to have been made by such
party or on its behalf with any broker or finder in connection with this
Lease or the transaction contemplated hereby.

                            RIDER TO LEASE AGREEMENT
                               DATED JUNE __, 1998

                                     BETWEEN

      RYAN SOUTHBANK II, L.L.C., A LIMITED LIABILITY COMPANY, AS LANDLORD,

                                       AND

                          MINDSPRING ENTERPRISES, INC.,
                                    AS TENANT

         THIS RIDER is an integral part of the attached Lease Agreement
between Ryan Southbank II, L.L.C., a Limited Liability Company, as Landlord,
and Mindspring Enterprises, Inc., as Tenant. In the event of any conflict
between the two, the terms of this Rider will govern. This Rider and the
attached Lease Agreement are called the "Lease."

25.      FINANCIAL INFORMATION:

         Tenant represents and warrants to Landlord that there has been no
material adverse change in the financial condition of Tenant between the
effective date of the information delivered to Landlord and the date of this
Lease. Tenant acknowledges that, but for the truth and completeness of the
financial information given to Landlord, as well as the truth of the foregoing
representations, Landlord would not have entered into this Lease with Tenant.

26.      PARKING:

         At no additional charge to Tenant during the term of this Lease and
any renewals, Landlord will provide Tenant with six (6) parking spaces for
every one thousand (1,000) square feet of space in the Premises, thirty (30)
of which will be covered (if Tenant elects to have covered spaces) and
reserved and the rest uncovered and unreserved, and all of which shall be in
the general parking areas within the Project as shown on EXHIBIT A. The cost
for constructing the covered spaces (if Tenant elects to have covered spaces)
(which Landlord estimates to be approximately $30,000) may, at Tenant's
election, be charged against the Tenant Improvement Allowance. Tenant's
parking privileges are contingent on Tenant's full compliance with the terms
and conditions of this Lease. While Tenant is in default hereunder, Tenant's
parking privileges will be suspended without further demand or notice from
Landlord.

27.      TENANT IMPROVEMENTS AND OTHER INCENTIVES:

         27.1. Landlord shall provide, at Landlord's sole cost and expense, a
base building (the "Building") with parking lot, driveways, sidewalks,
exterior lighting and landscaping. Attached as EXHIBIT E is a description of
the Building. Landlord shall also provide an Allowance for Tenant
Improvements to the Premises not to exceed twenty seven dollars ($27.00) per
square foot. Notwithstanding any provision in this Lease to the contrary,
Tenant shall have the right to apply the Allowance for Tenant Improvements
(not to exceed $27.00 per square foot) to Tenant Improvements and/or to the
moving allowance, lease assumption, signage and parking allowances in such
combination as Tenant may select, but without increase in Landlord's total
obligation, which shall not exceed $27.00 per square foot.

                                     20

<PAGE>

         27.2. If plans and specifications for the Tenant Improvements are
not attached to this Lease (the "Final Plans"), Landlord and Tenant will
mutually develop the Final Plans before Landlord will commence construction,
and both parties agree to negotiate in good faith to determine the Final
Plans. Landlord and Tenant shall determine the Final Plans within Thirty (30)
days from the date of this Lease. Agreement on the Final Plans by the
foregoing date is necessary to enable Landlord to obtain required permits
sufficiently early to commence construction on or about July 1, 1998. If
Landlord and Tenant fail to determine the Final Plans within such period of
time, each day of delay will extend, day-for-day, the Adjusted Delivery Date
in Paragraph 2 of this Lease.

         27.3. Landlord will construct the Tenant Improvements based upon the
Final Plans under a design/build format, on an open book basis at cost plus
5% for overhead and 3% for profit, together with Landlord's general
conditions charges which are included as a portion of the estimated cost
shown on EXHIBIT F attached hereto. EXHIBIT F, the Project Cost Estimate, is
subject to completion of the Final Plans as provided herein, and to
completion of detailed construction drawings and to solicitation of bids for
the work to be performed. Accordingly, the Project Cost Estimate is
preliminary and is subject to change. The Tenant Improvements will be
constructed in a good and workmanlike manner in accordance with the terms of
this Lease pursuant to applicable laws, rules and regulations. Subcontractor
contracts will be competitively bid where appropriate.

         Landlord will be required to construct and provide no additional
improvements other than the Tenant Improvements.

         27.4. If the actual cost of the Tenant Improvements exceeds the
Allowance, Tenant will pay the difference by a cash payment made to Landlord
within thirty (30) days following the issuance of the certificate of
occupancy for the Tenant Improvements. If the actual cost of the Tenant
Improvements is less than the Allowance. Any unused portion of the Tenant
Improvement Allowance shall be applied to rent payments in the regular order
of maturity; provided however, that the amount credited shall not exceed five
dollars ($5.00) per square foot; and provided that any unused portion of the
Tenant Improvement Allowance may in Tenant's discretion be applied to other
allowance items as permitted above.

         27.5. The Tenant Improvements will be the property of Landlord, and
upon expiration or termination of this Lease, Tenant will deliver the
Premises including the Tenant Improvements to Landlord in good condition,
normal wear and tear excepted.

         Landlord represents and warrants to Tenant (as of the commencement
of the Lease Term):

         (a) the Premises will be  structurally  sound,  and the mechanical
and electrical  systems  therein will be in good working order; and

         (b) the Premises will substantially comply with all legal
requirements (including without limitation the Americans With Disabilities
Act of 1990) and with applicable regulatory standards and codes, excepting
any noncompliance resulting from design error or acts of Tenant or its own
designers or consultants.

                                     21

28.      RENEWAL OPTION(S):

         Provided that Tenant is not in default under this Lease either at
the time it exercises the Renewal Options set forth below, or at the date a
Renewal Term begins, Tenant will have the right to renew this Lease for two
(2) successive five (5) year terms (the "Renewal Terms") by giving notice of
exercise of the Renewal Option to Landlord at least six (6) months before the
end of the Lease Term and the first Renewal Term. If Tenant fails to deliver
timely written notice of exercise of a Renewal Option to Landlord, all
Renewal Options shall lapse and Tenant will have no further privilege to
extend the Lease Term.

         Each Renewal Term shall be on the same terms and conditions of this
Lease (unless by their very nature inapplicable), except that Rent payable by
Tenant to Landlord during each Renewal Term shall be based on the prevailing
"market rental rate" for comparable space in competing buildings of similar
size, type, quality and location as reasonably calculated by Landlord for
each Renewal Term, BUT IN NO EVENT LESS than the rate in force at the end of
the preceding Lease Term. Determination of the effective "market rental rate"
will give appropriate consideration to rental rates for renewals, rental
escalations, tenant improvement allowances, common area charges, operating
costs, and other terms that would affect the economics in a similar lease
renewal at a competing building in the area.

         If Landlord and Tenant are unable to agree on the "market rental
rate" to be applied to the Property, Landlord and Tenant shall select a
highly qualified and reputable real estate professional with at least ten
(10) years of experience in the relevant leasing market (the "Arbiter") to
determine the "market rental rate." If Landlord and Tenant are unable to
agree on the Arbiter, the resident manager of the largest commercial real
estate brokerage house in Phoenix will select the Arbiter from a major
brokerage house other than his or her own. The term "largest" means the
brokerage house with the largest sales volume in the preceding calendar year.

         In addition to paying the Rent determined pursuant to this Paragraph
28, Tenant will continue to pay Tenant's Proportionate Share of Operating
Costs and all other sums required under this Lease during each Renewal Term.

         If this Lease, or Tenant's right to possession of the Premises,
shall expire or terminate for any reason whatsoever before Tenant exercises
the Renewal Options, or if Tenant has sublet or assigned all or any portion
of the Premises other than to a Tenant Affiliate, then immediately upon such
expiration or termination, subletting or assignment, the Renewal Options
shall simultaneously terminate and become null and void. The Renewal Options
are personal to

                                     22

<PAGE>

Tenant.  Under no  circumstances  shall a subtenant or an assignee other than
a Tenant  Affiliate have the right to exercise the Renewal Options.  TIME IS
OF THE ESSENCE OF THIS PROVISION.
