FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY THE MORE DETAILED INFORMATION
AND FINANCIAL STATEMENTS APPEARING ELSEWHERE IN THIS PROSPECTUS.
 
                                  THE COMPANY
 
    EarthLink Network, Inc. ("EarthLink" or the "Company") is an Internet
service provider ("ISP") that was formed to help users derive meaningful
benefits from the extensive resources of the Internet. The Company focuses on
providing reliable access, useful information, assistance and services to its
customers to encourage their introduction to the Internet and to help them have
a satisfying user experience.
 
    International Data Corporation estimates that the number of Internet users
was approximately 56 million at the end of 1995 and that this number will reach
approximately 200 million by the end of 1999. However, the Company believes that
many users have not been able to enjoy the benefits of the Internet.
Particularly for non-technical users, access to the Internet is often difficult.
In addition, for some users the volume and lack of organization of the
information on the Internet makes accessing useful information and entertainment
an intimidating task.
 
    EarthLink's principal strategy is to rapidly expand its customer base and
retain those customers who use its services principally by addressing these
problems. The Company provides its services through its EarthLink Network
TotalAccess software, which is designed to simplify access to the Internet
through an online registration feature and a "point and click" graphical user
interface. This software permits users to browse the Internet through use of
Netscape Communications Corporation's ("Netscape") Navigator ("Netscape
Navigator") or Microsoft Corporation's ("Microsoft") Internet Explorer
("Microsoft Explorer") (one or the other of which is included in each copy of
TotalAccess), or any other third-party browser that a customer may wish to use.
The Company also provides useful information to users through its extensive
World Wide Web site. On this site, users can find technical assistance
information, an on-line newsletter, links to numerous popular categories of
information and entertainment and many other items and services designed to
enhance users' satisfaction with their Internet experience. In addition, the
Company provides a monthly printed newsletter, as well as 24 hour customer and
technical support.
 
    The Company markets its services through print advertisements, an affinity
marketing program, a customer referral program and other marketing activities.
Its affinity marketing program includes relationships with, among others,
prominent print publication, software and hardware companies. For example,
Macmillan Publishing USA bundles EarthLink Network TotalAccess software with
several Internet-related book titles. Customer referrals have also been an
important source of new customers, and the Company provides economic incentives
to its customers to encourage these referrals. The Company believes that these
programs are a cost-effective means of acquiring new customers.
 
    The Company believes that its long-term success largely depends on
maintaining customer satisfaction with its services. Therefore, the Company will
continue to devote substantial resources to enhancing its service offerings,
expanding its technical support staff and expanding its World Wide Web site.
 
    EarthLink also seeks to enhance its revenues by offering business services,
including business Web sites, high-speed ISDN communications capability in
Southern California and frame relay connectivity. In addition, the Company
offers consumer services such as multiplayer Internet games and the EarthLink
online store.
 
    The Company has achieved a nationwide presence, without incurring
significant capital costs, by leasing access to dial-up points-of-presence
("POPs") from UUNET Technologies, Inc. ("UUNET") on a non-exclusive basis. The
Company also operates its own POPs in California. In addition, EarthLink has
agreed to lease POP access from PSINet, Inc. ("PSINet") on a non-exclusive
basis, and the Company plans to expand its own POPs in Northern California
within the next year. The Company will consider establishing its own POPs in
other areas if there is sufficient concentration of customers to support the
required capital investment.
 
    The Company was incorporated as a California corporation in May 1994 and
reincorporated as a Delaware corporation in June 1996. The Company's principal
executive offices are located at 3100 New York Drive, Pasadena, California
91107, and its telephone number is (818) 296-2400.

                                  RISK FACTORS
 
    THIS PROSPECTUS CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS AND
UNCERTAINTIES. ACTUAL EVENTS AND RESULTS COULD DIFFER MATERIALLY FROM THOSE
ANTICIPATED IN THESE FORWARD-LOOKING STATEMENTS AS A RESULT OF CERTAIN FACTORS,
INCLUDING THOSE SET FORTH IN THE FOLLOWING RISK FACTORS AND ELSEWHERE IN THIS
PROSPECTUS. INVESTMENT IN THE COMMON STOCK OFFERED HEREBY INVOLVES A HIGH DEGREE
OF RISK. PROSPECTIVE INVESTORS IN THE SHARES OFFERED HEREBY SHOULD CAREFULLY
CONSIDER THE FOLLOWING RISK FACTORS IN ADDITION TO THE OTHER INFORMATION
CONTAINED IN THIS PROSPECTUS.
 
LIMITED OPERATING HISTORY; HISTORY OF LOSSES AND EXPECTATIONS OF FUTURE LOSSES
 
    The Company was founded in May 1994 and began offering its services in July
1994. Accordingly, the Company has only a limited operating history upon which
an evaluation of its prospects can be made. Such prospects must be considered in
light of the substantial risks, expenses and difficulties encountered by new
entrants into the Internet services industry. The Company had net losses of
approximately $6.3 million from inception through 1995 and of approximately
$11.7 million for the six months ended June 30, 1996. As of June 30, 1996, the
Company had an accumulated deficit of approximately $16.7 million (exclusive of
$1.3 million of losses incurred while the Company was an S Corporation for tax
purposes, which, upon the Company's conversion to C Corporation status in June
1995, were charged to the Company's capital accounts). The Company expects that
it is likely to continue to incur net losses as it continues to expend
substantial resources on sales, marketing and administration, build its network
systems, develop new service offerings and improve its management information
systems. There can be no assurance that the Company will achieve or sustain
profitability or positive cash flow from its operations. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
COMPETITION
 
    The Internet services market in which the Company operates is extremely
competitive, and the Company expects competition in this market to intensify in
the future. The Company's current and prospective competitors include many large
companies that have substantially greater market presence and financial,
technical, marketing and other resources than the Company. The Company competes
(or in the future is expected to compete) directly or indirectly with the
following categories of companies: (i) national and regional ISPs such as Bolt
Beranek & Newman, Inc. ("BBN"), IDT Corporation ("IDT"), MindSpring Enterprises,
Inc. ("MindSpring"), Netcom On-line Communication Services, Inc. ("NETCOM"),
PSINet and UUNET; (ii) established online services such as America Online,
CompuServe, Prodigy and the Microsoft Network; (iii) computer software and
technology companies such as Microsoft; (iv) national telecommunications
companies such as AT&T Corp. ("AT&T"), MCI Communications Corporation ("MCI")
and Sprint Corporation ("Sprint"); (v) regional Bell operating companies
("RBOCs"); (vi) cable operators such as Comcast Corporation ("Comcast"),
Tele-Communications, Inc. ("TCI") and Time Warner, Inc. ("Time Warner"); and
(vii) nonprofit or educational Internet service providers.
 
    The entry of new participants from these categories and the potential entry
of competitors from other categories (such as computer hardware manufacturers)
will result in substantially greater competition for the Company. The ability of
these competitors or others to bundle services and products with Internet
connectivity services could place the Company at a significant competitive
disadvantage. In addition, competitors in the telecommunications industry may be
able to provide customers with reduced communications costs in connection with
their Internet access services, reducing the overall cost of Internet access and
significantly increasing pricing pressures on the Company. Among other
competitors who have recently introduced or enhanced their Internet offerings,
AT&T has recently expanded its Internet services offerings. The Company believes
that AT&T's expansion has substantially increased pricing pressure in the
industry. In addition, certain of the Company's online competitors, including
America Online, the Microsoft Network and Prodigy, have recently announced
unlimited access to the Internet and their proprietary content at flat rates
that are equal to the Company's monthly flat rate, and do not require a set-up
fee. Certain of the RBOCs have also announced competitive flat-rate pricing for
unlimited access (without a set-up fee for at least some period of time). As a
result, competition for active users of Internet services should intensify.
There can be no assurance that the
 
                                       5
<PAGE>
Company will be able to offset the adverse effect on revenues of any necessary
price reductions resulting from competitive pricing pressures by increasing the
number of its customers, by generating higher revenue from enhanced services, by
reducing costs or otherwise.
 
    Competition is also expected to focus increasingly on overseas markets, in
which Internet services are just beginning to be introduced. The Company is not
presently seeking to penetrate overseas markets. To the extent that the ability
to provide Internet services overseas becomes a competitive advantage in the
Internet services industry, the failure of the Company to penetrate overseas
markets may result in the Company being at a competitive disadvantage relative
to other Internet access providers.
 
    There can be no assurance that the Company will have the financial
resources, technical expertise or marketing and support capabilities to compete
successfully. See "-- Dependence on Third-Party Network Providers," "-- New and
Uncertain Market; Dependence on Continued Growth in Use of the Internet;
Uncertainty of Customer Retention," "-- Dependence on Network Infrastructure;
Capacity; Risk of System Failure; Security Risks," "-- Dependence on Affinity
Marketing and Distribution Relationships," "Business -- Competition" and "--
Government Regulation."
 
RISKS ASSOCIATED WITH MANAGEMENT OF POTENTIAL GROWTH
 
    The Company's growth has placed, and is expected to continue to place, a
significant strain on its managerial, operational, financial and information
systems resources. To accommodate its current size and manage growth, the
Company must continue to implement and improve its operational, financial and
information systems, and expand, train and manage its employee base.
Additionally, expansion of the Company's information and network systems is
required to accommodate its growth. There can be no assurance that the Company
will be able to effectively manage the expansion of its operations, or that the
Company's facilities, systems, procedures or controls will be adequate to
support the Company's operations. The inability of the Company to effectively
manage its future growth would have a material adverse effect on the Company.
 
    Demand on the Company's network infrastructure, technical staff and
resources has grown rapidly with the Company's expanding customer base, and the
Company has experienced difficulties satisfying the demand for its Internet
services. There can be no assurance that the Company's infrastructure, technical
staff and resources will be adequate to facilitate the Company's growth. In
addition, delays have occurred in establishing Internet accounts for the
Company's customers, and customers have experienced significant delays in
contacting, and in receiving responses from, the Company's customer and
technical support personnel. There can be no assurance that the Company will be
able to establish accounts or provide customer or technical support on a timely
basis, or that any delays will not result in a loss of customers. The Company
believes that its ability to provide timely access for customers and adequate
customer and technical support will largely depend on its ability to attract,
identify, train, integrate and retain qualified personnel. Failure to provide
adequate customer and technical support services will adversely affect the
Company's ability to increase its customer base, and could therefore have a
material adverse effect on the Company. See "-- Dependence on Network
Infrastructure; Capacity; Risk of System Failure; Security Risks,"
"-- Dependence on Key Personnel," "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Overview" and "Business --
Employees."
 
DEPENDENCE ON THIRD-PARTY NETWORK PROVIDERS
 
    As of October 31, 1996, the Company maintained 20 Company-owned POPs and
provided Internet access through an additional 336 UUNET POPs to which it has
acccess on a non-exclusive basis. The Company is dependent on UUNET, a
third-party provider of Internet network infrastructure, to continue to provide
the Company's customers with access to the Internet through UUNET's systems of
POPs. The Company recently executed an agreement with PSINet to access PSINet's
nationwide system of POPs on a non-exclusive basis. The Company believes that
its customers will have Internet access through PSINet POPs by the end of 1996.
The Company's agreement with UUNET has a term expiring in March 1999 (subject to
 
                                       6
<PAGE>
earlier cancellation after March 1998 upon one year's prior notice, but provided
that if this notice is given, EarthLink is required to begin to reduce its usage
of UUNET's POPs in accordance with a schedule set forth in the agreement). If
the agreement expires at the end of its term, it is automatically renewed for
consecutive one-year terms unless prior notice of termination is given. The
PSINet agreement has a term expiring in July 1998 after which it is
automatically renewed for consecutive one-year terms unless prior notice of
termination is given.
 
    Both UUNET and PSINet provide POP access to ISPs other than the Company and
to entities offering online services. UUNET provides such access to, among
others, Microsoft for the Microsoft Network, a competitor of the Company. The
Microsoft Network has recently announced unlimited access to the Internet at a
flat rate, which could substantially increase utilization of UUNET POPs by
subscribers to the Microsoft Network. Microsoft is a stockholder of UUNET's
parent corporation, MFS Communications Company, Inc. ("MFS"), and therefore
could be granted preferred access to UUNET's system of POPs. Accordingly, if
customer usage of the Microsoft Network materially increases, the Company's
access to UUNET's system of POPs may be limited and the Company's customers may
experience increased difficulties in gaining access to the Internet. As usage of
UUNET's and PSINet's POPs by other ISPs' and online service providers' customers
increases, system performance experienced by EarthLink's customers may degrade
and POP access may become limited. UUNET and PSINet also independently compete
with the Company.
 
    UUNET was recently acquired by MFS, a supplier of local and long distance
telephone service. In August 1996, MFS and WorldCom, Inc. ("WorldCom") announced
that MFS and WorldCom had executed a definitive agreement for the merger of MFS
into WorldCom. The parties also announced that they expect to consumate this
merger during the first quarter of 1997. There can be no assurance that,
following the expiration of the Company's current agreement with UUNET, the
Company will continue to have access to UUNET's POPs or that such access, if
provided, will be available to the Company on acceptable terms.
 
    The Company's customers generally pay a fixed monthly fee for the Company's
Internet services. Under the Company's current agreement with UUNET, the Company
pays UUNET a monthly fee equal to the greater of a specified minimum or an
amount that varies based primarily on peak customer usage. The Company also pays
UUNET an additional fee to the extent that hours of usage exceed a formula set
forth in the agreement. The Company has recently experienced increasing per
customer usage of its services. If the number of hours used by EarthLink
customers accessing the Internet through UUNET increases beyond the amount
provided for in the agreement, the fees paid by the Company to UUNET would
increase, which would adversely affect the Company's operating margins.
 
    As noted above, under the Company's current agreement with UUNET, the
Company pays UUNET a monthly fee equal to the greater of a specified minimum or
an amount that varies based primarily on peak customer usage. The specified
minimum amount increases over the term of the agreement. The Company's operating
margins could be adversely affected if the Company is unable to increase its
customer base so as to avoid paying the increasing minimum amount. See "--
Dependence on Network Infrastructure; Capacity; Risk of System Failure; Security
Risks," "Management's Discussion and Analysis of Financial Condition and Results
of Operations -- Results of Operations -- Cost of Revenues," "Business --
EarthLink's Services" and "-- Customers, POPs and Network Infrastructure."
 
    The inability or unwillingness of one or both of UUNET and PSINet to provide
POP access to the Company's customers, or the Company's inability to secure
alternative POP arrangements if necessary, could limit the Company's ability to
provide Internet access to its customers, and could, in turn, have a material
adverse effect on the Company. See "-- Dependence on Network Infrastructure;
Capacity; Risk of System Failure; Security Risks."
 
FACTORS AFFECTING OPERATING RESULTS; POTENTIAL FLUCTUATIONS IN QUARTERLY RESULTS
 
    The Company's operating results may fluctuate significantly in the future as
a result of a variety of factors, many of which are beyond the Company's
control. These factors include the rates of, and costs
 
                                       7
<PAGE>
associated with, new customer acquisition, customer retention, capital
expenditures and other costs relating to the expansion of operations, including
upgrading the Company's systems and infrastructure, the timing and market
acceptance of new and upgraded service introductions, changes in the pricing
policies of the Company and its competitors, changes in operating expenses
(including telecommunications costs), personnel changes, the introduction of
alternative technologies, the effect of potential acquisitions, increased
competition in the Company's markets and other general economic factors. In
addition, a significant portion of the Company's expenses are fixed; therefore,
the Company's operating margins are particularly sensitive to fluctuations in
revenues. Due to these factors, in some future quarter the Company's operating
results may fall below the expectations of securities analysts and investors. In
such event, the market price of the Company's Common Stock would likely be
materially and adversely affected.
 
    In May 1996, the Company entered into an agreement with National Media
Corporation ("NMC"), a producer of infomercials and commercials, pursuant to
which NMC agreed to produce and broadcast 15-second and 60-second commercials
for EarthLink's services. Under this agreement, in addition to certain fees
payable to NMC, the Company agreed to issue warrants to NMC to purchase up to
100,000 shares of Common Stock having an exercise price of $4.88 per share, upon
the completion by NMC, subject to the Company's approval, of the 15-second and
60-second commercials, and to issue warrants to NMC to purchase one share of
Common Stock for each customer generated by this relationship, up to 600,000
shares of Common Stock. The exercise price of such additional warrants earned
through December 31, 1997 will be $4.88 per share, and thereafter the exercise
price will be the fair market value of the Common Stock on the date of grant.
Upon issuance of any such warrants, the Company will be required to record in
the quarter in which such warrant is issued a non-cash charge against earnings
in an amount equal to the fair value of the warrant on the date of issuance. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Potential Fluctuations in Quarterly Results."
 
DEPENDENCE ON NETWORK INFRASTRUCTURE; CAPACITY; RISK OF SYSTEM FAILURE; SECURITY
RISKS
 
    The future success of the Company's business will depend on the capacity,
reliability and security of the Company's network infrastructure, including the
POP sites to which the Company has access through UUNET and PSINet. The Company
will be required to expand and improve this infrastructure as the number of
customers and the amount and type of information its customers communicate over
the Internet increases, and the means by which customers connect to the Internet
evolve. Such expansion and improvement may require substantial financial,
operational and managerial resources. There can be no assurance that the Company
will be able to expand or improve its network infrastructure to meet any
additional demand or changing customer requirements on a timely basis or at a
commercially reasonable cost, if at all.
 
    Capacity constraints have occurred, and may occur in the future, both at the
level of particular POPs (affecting only customers attempting to use that
particular POP) and in connection with system wide services (such as email and
news services, which can affect all customers). From time to time, the Company
has experienced delayed delivery from suppliers of new telephone lines, modems,
servers and other equipment used by the Company in providing its services. Any
severe shortage of new telephone lines, modems, servers or other equipment could
result in incoming access lines becoming full during peak times, causing busy
signals for customers who are trying to connect to the Internet. Similar
problems may occur if the Company is unable to expand the capacity of its
various network, email, Web and other servers quickly enough to keep pace with
demand from the Company's expanding customer base. If the capacity of such
servers is exceeded, customers will experience delays when trying to use a
particular service. Further, if the Company does not maintain sufficient
capacity in its network connections, customers will experience a general slow
down of all services on the Internet. Any of these events could cause customers
to terminate use of the Company's services. Accordingly, any failure of the
Company to expand or enhance its network infrastructure on a timely basis, or to
adapt it to an expanding customer base, changing customer requirements or
evolving industry standards, could have a material adverse effect on the
Company. See "-- Dependence on Third-Party Network Providers" and "Business --
Customers, POPs and Network Infrastructure."
 
                                       8
<PAGE>
    The Company's operations are dependent on its ability to protect its
computer equipment against damage from fire, earthquake, power loss,
telecommunication failure and similar events. The occurrence of a natural
disaster or another unanticipated problem at the Company's headquarters and
network hub or at POPs through which customers connect to the Internet could
cause interruptions in the services provided by the Company. For example, in
October 1996, the Company experienced a power outage at its network hub in Los
Angeles, which caused a several hour system wide disruption of the Company's
Internet services. Services were restored when the Company installed a backup
power source, on which it is still relying. The Company's computer equipment,
including critical equipment dedicated to its Internet services, is located in
Los Angeles and Pasadena, California. The Company will relocate its data center
from Los Angeles to a facility adjacent to its Pasadena headquarters in the near
future. The risks associated with such a move include network and services down
time, loss of data, loss of system integrity and the risk of system failure. The
occurrence of any of these events could have a material adverse effect on the
Company's ability to provide Internet services to its customers, and, in turn,
on the Company. In addition, failure of the Company's telecommunications
providers to provide the data communications capacity required by the Company as
a result of a natural disaster, operational disruption or for any other reason
could cause interruptions in the services provided by the Company.
 
    The Company's network infrastructure, including the POP sites to which the
Company has access through UUNET and PSINet, is vulnerable to computer viruses
and other similar disruptive problems caused by its customers, other Internet
users or other third parties. Computer viruses and other problems could lead to
interruptions, delays in or cessation of service to the Company's customers, as
well as corruption of the Company's or its customers' computer systems.
Inappropriate use of the Internet by third parties could also potentially
jeopardize the security of confidential information stored in the computer
systems of the Company or those of its customers, which may cause losses to the
Company or its customers, or deter certain persons from using the Company's
services. The Company expects that its customers may increasingly use the
Internet for commercial transactions in the future. Any network malfunction or
security breach could cause these transactions to be delayed, not completed or
completed with compromised security. Alleviating problems caused by computer
viruses or other inappropriate uses or security breaches may cause
interruptions, delays or cessation in service to the Company's customers, which
could have a material adverse effect on the Company. There can be no assurance
that customers or others will not assert claims of liability against the Company
as a result of any such failure.
 
    The Company does not presently maintain redundant or backup Internet
services or backbone facilities or other redundant computing and
telecommunications facilities. Any accident, incident or system failure that
causes interruptions in the Company's operations could have a material adverse
effect on the Company's ability to provide Internet services to its customers,
and, in turn, on the Company. See "-- Risks Associated with Management of
Potential Growth," and "-- Dependence on Third-Party Network Providers."
 
FUTURE ADDITIONAL CAPITAL REQUIREMENTS
 
    The Company believes that the net proceeds from this Offering, together with
other available cash, will be sufficient to meet the Company's operating
expenses and capital requirements for at least the next 12 months. However, the
Company's capital requirements depend on numerous factors, including the rate of
market acceptance of the Company's services, the Company's ability to maintain
and expand its customer base, the rate of expansion of the Company's network
infrastructure, the level of resources required to expand the Company's
marketing and sales organization, information systems and research and
development activities, the availability of hardware and software provided by
third-party vendors and other factors. The timing and amount of such capital
requirements cannot accurately be predicted. If capital requirements vary
materially from those currently planned, the Company may require additional
financing sooner than anticipated. The Company has no commitments for any
additional financing, and there can be no assurance that any such commitments
can be obtained on favorable terms, if at all. Any additional equity financing
may be dilutive to the Company's stockholders, and debt financing, if available,
may involve restrictive covenants with respect to dividends, raising future
capital and other financial and operational matters. If the Company is unable to
 
                                       9
<PAGE>
obtain additional financing as needed, the Company may be required to reduce the
scope of its operations or its anticipated expansion, which could have a
material adverse effect on the Company, as well as the market price of the
Common Stock. See "-- Risks Associated with Management of Potential Growth," "--
Dependence or Network Infrastructure; Capacity; Risk of System Failure; Security
Risks," "Use of Proceeds" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Liquidity and Capital Resources."
 
DEPENDENCE ON TELECOMMUNICATIONS CARRIERS AND OTHER SUPPLIERS
 
    The Company relies on local telephone companies and other companies to
provide data communications capacity via local telecommunications lines and
leased long distance lines. The Company is subject to potential disruptions in
these telecommunications services and may have no means of replacing these
services, on a timely basis or at all, in the event of such disruption.
 
    In addition, the Company is dependent on certain third-party suppliers of
hardware components. Certain components used by the Company in providing its
network services are currently acquired from limited sources. The Company also
depends on third-party software vendors to provide the Company with much of its
Internet software, including Netscape Navigator and Microsoft Explorer, the
World Wide Web browser software that the Company licenses from Netscape and
Microsoft, respectively. Failure of the Company's suppliers to provide
components and products in the quantities, at the quality levels or at the times
required by the Company, or an inability by the Company to develop alternative
sources of supply if required, could adversely affect the Company's ability to
effectively support the growth of its customer base in a timely manner and
increase its costs of expansion. Moreover, because Netscape Navigator and
Microsoft Explorer are the two most widely used Web browsers, the failure of
Netscape or Microsoft to continue to provide World Wide Web browser software to
the Company could have a material adverse effect on the Company.
 
    The Company's suppliers and telecommunications carriers also sell or lease
services and products to the Company's competitors, and some of these carriers
are, and in the future others may become, competitors of the Company. There can
be no assurance that the Company's suppliers and telecommunications carriers
will not enter into exclusive arrangements with the Company's competitors or
otherwise stop selling or leasing their services or products to the Company. See
"-- Competition," "Business -- Supplier Relationships" and
"-- Marketing."
 
DEPENDENCE ON AFFINITY MARKETING AND DISTRIBUTION RELATIONSHIPS
 
    A significant number of the Company's customers have been generated through
its relationships with its affinity marketing partners. The Company relies on
these marketing relationships to assist it with distributing the EarthLink
Network TotalAccess software, which enables users to register as customers and
to access the Company's Internet services. There can be no assurance that the
Company's current affinity marketing partners will continue to distribute the
Company's software or will be successful in developing new customers for the
Company's services. The Company's inability to maintain its affinity marketing
relationships or establish new affinity marketing relationships could result in
delays and increased costs in expanding its customer base, which could, in turn,
have a material adverse effect on the Company. See "Business -- Marketing --
Affinity Marketing Partners Program."
 
NEW AND UNCERTAIN MARKET; DEPENDENCE ON CONTINUED GROWTH IN USE OF THE INTERNET;
UNCERTAINTY OF     CUSTOMER RETENTION
 
    EarthLink's future success is substantially dependent on continued growth in
the use of the Internet. Rapid growth in the use of, and interest in, the
Internet, and in particular the World Wide Web, is a recent phenomenon and there
can be no assurance that Internet usage will become more widespread, that
extensive Internet content will continue to be developed or that extensive
Internet content will continue to be accessible at no or nominal cost. The
Internet may not prove to be viable for a number of reasons, including
potentially inadequate development of the necessary infrastructure or of
performance improvements. If use of the Internet
 
                                       10
<PAGE>
does not continue to grow, the Company would be materially and adversely
affected. Conversely, to the extent that the Internet continues to experience
significant growth in the number of users and level of use, there can be no
assurance that the Internet infrastructure will be able to support the demands
placed on it by such potential growth. See "-- Risks Associated with Management
of Potential Growth."
 
    The sales, marketing and other costs to the Company of acquiring new
customers are substantial relative to the monthly fee derived from such
customers. Accordingly, the Company believes that its long-term success largely
depends on its ability to retain its existing customers, while continuing to
attract new customers. The Company continues to invest significant resources in
its infrastructure and customer and technical support capabilities. However,
there can be no assurance that such investment will improve customer retention.
Because the Internet services market is new and the variety of available
services is not well understood by new and potential customers, it is difficult,
if not impossible, for the Company to predict future customer retention rates.
Moreover, intense competition from competitors, some of whom offer many free
hours of services for new customers, have most likely caused, and may continue
to cause, some of the Company's customers to switch to a competitor's service.
In addition, a certain number of new Internet users experience the Internet only
as a novelty and do not become consistent users of Internet services. These
factors adversely affect the Company's customer retention rates. See "-- Risks
Associated with Management of Potential Growth," "-- Dependence on Network
Infrastructure; Capacity; Risk of System Failure; Security Risks," "--
Competition" and "Management's Discussion and Analysis of Financial Condition
and Results of Operations -- Overview."
 
RAPID TECHNOLOGICAL CHANGE
 
    The market for Internet services is characterized by rapidly changing
technology, evolving industry standards, changes in customer needs and frequent
new service and product introductions. The Company's future success will depend,
in part, on its ability to use leading technologies effectively, to continue to
develop its technical expertise, to enhance its existing services and to develop
new services that meet changing customer needs on a timely and cost-effective
basis and obtain market acceptance. There are currently under development a
number of alternative methods for users to connect to the Internet, including
cable modems and satellite and other wireless telecommunications technologies.
Any failure on the part of the Company to use new technologies effectively, to
develop its technical expertise and new services or to enhance existing services
on a timely basis, either internally or through arrangements with third parties,
could have a material adverse effect on the Company.
 
DEPENDENCE ON KEY PERSONNEL
 
    The Company is highly dependent on the technical and managerial skills of
its key employees, including technical, sales, marketing, information systems,
financial and executive personnel, and on its ability to identify, hire and
retain additional personnel. To accomodate its current size and manage its
anticipated growth, the Company must maintain and expand its employee base.
Competition for key personnel, particularly persons having technical expertise,
is intense, and there can be no assurance that the Company will be able to
retain existing personnel or to identify or hire additional personnel. The need
for such personnel is particularly important given the strains on the Company's
existing infrastructure and the need to anticipate the demands of future growth.
As of December 31, 1995 and September 30, 1996, the Company had 196 and 480
full-time employees, respectively. In particular, the Company is highly
dependent on the continued services of its senior management team, which
currently is composed of a small number of individuals, most of whom only
recently joined the Company. The inability to attract, hire or retain the
necessary technical, sales, marketing, information systems, financial and
executive personnel, or the loss of the services of any member of the Company's
senior management team, could have a material adverse effect on the Company. See
"-- Risks Associated with Management of Potential Growth," "Business --
Employees" and "Management."

GOVERNMENT REGULATION
 
    The Company provides Internet services, in part, through data transmissions
over public telephone lines. These transmissions are governed by regulatory
policies establishing charges and terms for wire line communications. The
Company is not currently subject to direct regulation by the Federal
Communications Commission (the "FCC") or any other governmental agency, other
than regulations applicable to businesses generally. However, in the future the
Company could become subject to regulation by the FCC or another regulatory
agency as a provider of basic telecommunications services. For example, a number
of long distance telephone carriers recently filed a petition with the FCC
seeking a declaration that Internet telephone service is a "telecommunications
service" subject to common carrier regulation. Such a declaration, if enacted,
would create substantial barriers to the Company's entry into the Internet
telephone market. The FCC has requested comments on this petition, but has not
set a deadline for issuing a final decision.
 
    The recently enacted Telecommunications Act of 1996 (the "Telecommunications
Act") contains certain provisions that lift, or establish procedures for
lifting, certain restrictions relating to the RBOCs' ability to engage directly
in the Internet access business. The Telecommunications Act also makes it easier
for national long distance carriers such as AT&T to offer local telephone
service and allows RBOCs to provide electronic publishing of information and
databases. Competition from these companies could have a material adverse effect
on the Company. See "Business -- Government Regulation."
 
POTENTIAL LIABILITY
 
    The case law relating to the liability of ISPs and online services companies
for information carried on or disseminated through their networks has not yet
been definitively established. Several private lawsuits seeking to impose such
liability upon ISPs and online services companies are currently pending.
Although no such claims have been asserted against the Company to date, there
can be no assurance that such claims will not be asserted in the future, or if
asserted, will not be successful. The Telecommunications Act imposes fines on
any entity that knowingly (i) uses any interactive computer service or
telecommunications device to send obscene or indecent material to minors; (ii)
makes obscene or indecent material available to minors via an interactive
computer service; or (iii) permits any telecommunications facility under such
entity's control to be used for the purposes detailed above. The standard for
determining whether an entity acted "knowingly" has not yet been established
although a federal district court panel recently issued a preliminary injunction
preventing enforcement of this part of the Telecommunications Act. As the law in
this area develops, the potential imposition of liability upon the Company for
information carried on and disseminated through its network could require the
Company to implement measures to reduce its exposure to such liability. The
implementation of such measures could require the expenditure of substantial
resources or the discontinuation of certain service offerings. Any costs that
are incurred as a result of such expenditure, contesting any such asserted
claims or the imposition of liability could have a material adverse effect on
the Company.
 
    Due to the increasing use of the Internet, it is possible that additional
laws and regulations may be adopted with respect to the Internet covering issues
such as content, user privacy, pricing and copyright and intellectual property
protection and infringement. Changes in the regulatory environment relating to
the Internet services industry, including regulatory changes that directly or
indirectly affect telecommunication costs or increase the likelihood or scope of
competition, could have a material adverse effect on the Company.
 
PROPRIETARY RIGHTS; INFRINGEMENT CLAIMS
 
    The Company believes that its success is dependent in part on its technology
and its continuing right to use such technology. The Company relies on a
combination of copyright, trademark and trade secret laws and contractual
restrictions to establish and protect its technology. It is the Company's policy
to require employees, consultants and, when possible, suppliers to execute
confidentiality agreements upon the commencement of their relationships with the
Company. There can be no assurance that the steps taken by the Company will be
 
                                       12
<PAGE>
adequate to prevent misappropriation of its technology and other proprietary
property or that the Company's competitors will not independently develop
technologies that are substantially equivalent or superior to the Company's
technology.
 
    The Company has obtained authorization, typically in the form of a license,
to distribute third-party software incorporated in the EarthLink Network
TotalAccess software product for Windows 3.1, Windows 95 and Macintosh
platforms. Most of these licenses have one-year terms and automatically renew
for additional one-year terms in the absence of notice of termination from the
other party, but are generally terminable earlier upon the occurence of certain
events (and, with respect to Microsoft, is terminable by Microsoft or the
Company at will). Applications licensed by the Company include Netscape
Navigator, Microsoft Explorer and MacTCP software from Apple Computer, Inc.
("Apple"). There can be no assurance that the Company will be able to maintain
its existing licenses or successfully obtain necessary license renewals in the
future. The failure to maintain or renew its licenses in the future could have a
material adverse effect on the Company.
 
    There can be no assurance that third parties will not assert that the
Company's services and products infringe their proprietary rights. From time to
time, the Company has received communications from third parties alleging that
certain of the names or marks for the Company's services infringe the trademarks
of such parties. To date, no such claims have had an adverse effect on the
Company's ability to market and sell its services. However, there can be no
assurance that those claims will not have an adverse effect in the future or
that other parties will not assert infringement claims against the Company in
the future with respect to current or future services. Such claims could result
in substantial costs and diversion of resources, even if ultimately decided in
favor of the Company, and could have a material adverse effect on the Company,
particularly if judgments on such claims are adverse to the Company. In the
event a claim is asserted alleging that the Company has infringed the
proprietary technology or information of a third party, the Company may be
required to seek licenses to continue to use such intellectual property. There
can be no assurance, however, that such licenses would be offered or obtained on
commercially reasonable terms, if at all, or that the terms of any offered
licenses will be acceptable to the Company. The failure to obtain the necessary
licenses or other rights could have a material adverse effect on the Company.
See "Business -- Proprietary Rights."
 
INTEGRATION OF POTENTIAL ACQUISITIONS
 
    As part of its business strategy, EarthLink may make acquisitions of, or
significant investments in, complementary companies, services or technologies,
although no such acquisitions or investments are currently pending. Any such
future transactions would be accompanied by the risks commonly encountered in
making acquisitions of companies, services and technologies. Such risks include,
among other things, the difficulty associated with assimilating the operations
and personnel of the acquired companies, the potential disruption of the
Company's ongoing business, the inability of management to maximize the
financial and strategic position of the Company through the successful
integration of acquired network facilities, technology, rights and other assets,
additional expenses associated with the amortization of acquired intangible
assets, the inability to maintain uniform standards, controls, procedures and
policies and the impairment of relationships with employees and customers as a
result of the integration of new management personnel. There can be no assurance
that the Company will be successful in overcoming these risks or any other
problems encountered in connection with any such acquisitions. See "Use of
Proceeds" and "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Potential Fluctuations in Quarterly Results."
 
CONTROL BY DIRECTORS, EXECUTIVE OFFICERS AND AFFILIATED ENTITIES
 
    The Company's directors, executive officers and entities affiliated with
them will, in the aggregate, beneficially own approximately    % of the
outstanding shares of Common Stock following this Offering (   % if the
Underwriter's over-allotment option is exercised in full). These stockholders,
if acting together, would be able to significantly influence all matters
requiring approval by the stockholders of the Company, including the election of
directors and the approval of mergers or other business combination
transactions. See "Principal Stockholders."
 
                                       13
<PAGE>
SHARES ELIGIBLE FOR FUTURE SALE
 
    Sales of a substantial number of shares of the Common Stock in the public
market following this Offering could adversely affect the market price of the
Common Stock. The number of shares of Common Stock available for sale in the
public market is limited by restrictions under the Securities Act of 1933, as
amended (the "Securities Act"), and lock-up agreements under which the holders
of       shares of Common Stock,       shares of Series A Convertible Preferred
Stock and warrants, options and convertible securities to purchase      shares
of Common Stock (including all of the Company's officers and directors) have
agreed not to sell or otherwise dispose of any of their shares of Common Stock,
any options or warrants to acquire shares of Common Stock or securities
exchangeable or convertible into shares of Common Stock for a period of one year
after the date of this Prospectus without the prior written consent of the
Underwriter. However, the Underwriter may, in its sole discretion and at any
time without notice, release all or any portion of the securities subject to
such lock-up agreements. Further, the holders of substantially all of the shares
of Common Stock outstanding prior to this Offering as well as holders of certain
warrants and convertible debt are parties to registration rights agreements. The
exercise of these registration rights and subsequent sale of a substantial
number of shares of the Common Stock in the public market could adversely affect
the market price of the Common Stock. See "Description of Capital Stock --
Registration Rights," "Shares Eligible for Future Sale" and "Underwriting."
 
EFFECT OF CERTAIN CHARTER AND BYLAW PROVISIONS
 
    The Company's Certificate of Incorporation and Bylaws contain certain
provisions that may discourage proposals or bids to acquire the Company. These
provisions could limit the price that investors might be willing to pay for
shares of the Common Stock. Certain of such provisions allow the Company to
issue Preferred Stock, the rights and preferences of which may be specified by
the Board of Directors at any time prior to issuance, without further
stockholder approval, and could have the effect of delaying, deferring or
preventing a change in control of the Company. The Company also will be subject
to Section 203 of the Delaware General Corporation Law which, under certain
circumstances, could delay, defer or prevent a business combination with an
"interested stockholder." Following the first meeting of its stockholders
subsequent to this Offering, and provided that there are 800 or more beneficial
owners of the Common Stock, the Company anticipates that it will seek
stockholder approval to divide its Board into three classes, each serving a
staggered three-year term. See "Description of Capital Stock."
 
NO PUBLIC MARKET FOR COMMON STOCK; POTENTIAL VOLATILITY OF STOCK PRICE
 
    Prior to this Offering, there has been no public market for the Common
Stock, and there can be no assurance that a regular trading market will develop
and continue after this Offering or that the market price of the Common Stock
will not decline below the initial public offering price. The initial public
offering price will be determined through negotiations between the Company and
the Underwriter and may not be indicative of the market price of the Common
Stock following this Offering. Among the factors to be considered in such
negotiations are an estimate of the business potential of the Company, the
present state of the Company's development, an assessment of the Company's
management, prevailing market conditions, the demand for similar securities of
comparable companies and other factors deemed relevant. The stock markets have
experienced price and volume fluctuations that have particularly affected the
stocks of technology companies, resulting in changes in the market prices of the
stocks of many companies that may not have been directly related to the
operating performance of those companies. Such broad market fluctuations may
adversely affect the market price of the Common Stock following this Offering.
In addition, the market price of the Common Stock following this Offering may be
highly volatile. Factors such as variations in the Company's financial results,
comments by securities analysts, announcements of technological innovations or
new products by the Company or its competitors, changing government regulations,
developments concerning the Company's proprietary rights or litigation may have
a material adverse effect on the market price of the Common Stock. See
"Underwriting."

<PAGE>
IMMEDIATE AND SUBSTANTIAL DILUTION
 
    Assuming an initial public offering price of $     per share, investors
purchasing shares of Common Stock in this Offering will incur immediate and
substantial dilution in net tangible book value of the Common Stock of $   per
share. To the extent that currently outstanding options, warrants and
convertible debt are exercised or converted, there will be further dilution. See
"Dilution."
 
                                USE OF PROCEEDS
 
    The net proceeds to the Company from the sale of the shares of Common Stock
offered hereby are estimated to be approximately $         ($         if the
Underwriter's over-allotment option is exercised in full) at an assumed initial
public offering price of $     per share, after deducting estimated underwriting
discounts and commissions and offering expenses payable by the Company.
 
    EarthLink expects to use the net proceeds of this Offering to finance sales
and marketing activities, leasehold improvements, investments in network
equipment, information systems and office equipment. In addition, the Company
expects to use the net proceeds for new service introductions and for working
capital and other general corporate purposes. The Company intends to use a
portion of the net proceeds of this Offering to repay approximately $2.95
million of short-term indebtedness (which bears interest at 10% per annum and
matures in June 1997). The Company also intends to repay $5 million of
outstanding convertible debt to UUNET (which bears interest at a floating rate
of prime plus 2% per annum (10.25% for November 1996) and matures in October
1997), unless UUNET decides to convert such debt to Common Stock prior to
repayment. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Liquidity and Capital Resources" and "Certain
Transactions."
 
    The amounts actually expended for each purpose will be determined at the
discretion of the Company's management. The Company's future capital
requirements and the allocation of the net proceeds of this Offering will depend
on many factors, including the rate of market acceptance of the Company's
services, the Company's ability to expand and maintain its customer base, the
rate of expansion of the Company's network infrastructure, the level of
resources required to expand the Company's marketing and sales organization,
information systems and research and development activities, the availability of
hardware and software provided by third-party vendors and other factors. The
Company also anticipates that it may use a portion of the net proceeds to
acquire complementary product and service lines, technology, equipment, other
companies or interests in other companies. While the Company from time to time
has engaged in preliminary discussions concerning possible acquisitions,
investments or joint ventures, it has no present understandings, commitments,
agreements or active negotiations with respect to any such transaction.
 
    Pending such uses, the net proceeds of this Offering will be invested in
short-term, investment grade, interest-bearing securities. The Company believes
that the net proceeds from this Offering, together with other available cash
will be sufficient to meet the Company's operating expenses and capital
requirements for at least the next 12 months. See "Risk Factors -- Future
Additional Capital Requirements" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Liquidity and Capital
Resources."
 
                                DIVIDEND POLICY
 
    The Company has not paid any dividends since its inception and does not
intend to pay any dividends in the foreseeable future. The payment of future
cash dividends, if any, will be at the sole discretion of the Board of
Directors.

initial public offering price of $     per share and the application of the
estimated net proceeds therefrom.

(1) The Company issued 2,727,273 shares of Series A Convertible Preferred Stock
    subsequent to June 30, 1996.
 
(2) This amount excludes the following securities outstanding or reserved for
    future grant as of October 31, 1996: (i) 2,011,500 shares of Common Stock
    subject to options outstanding under the Company's 1995 Stock Option Plan
    having a weighted average exercise price of $3.70 per share, (ii) 2,662,888
    shares of Common Stock subject to outstanding warrants and non-plan stock

                                    DILUTION
 
    The pro forma net tangible book value of the Common Stock as of June 30,
1996 was negative $2,892,000, or approximately negative $0.20 per share. Pro
forma net tangible book value per share represents the amount of the Company's
total tangible assets less total liabilities, divided by the pro forma number of
shares of Common Stock outstanding (assuming the issuance, on June 30, 1996, of
the Company's Series A Convertible Preferred Stock and the conversion of such
stock into shares of Common Stock). After giving effect to the sale by the
Company of the     shares of Common Stock offered hereby at an assumed initial
public offering price of $   per share and after deducting estimated
underwriting discounts and commissions and offering expenses payable by the
Company, the pro forma net tangible book value of the Company as of June 30,
1996 would have been $         , or approximately $   per share. This represents
an immediate increase in the net tangible book value of $   per share to
existing stockholders and an immediate dilution of $   per share to new
investors purchasing shares of Common Stock in this Offering. Dilution per share
represents the difference between the amount per share paid by purchasers of
shares of Common Stock in the Offering made hereby and the net tangible book
value per share of Common Stock immediately after completion of this Offering.
 
    The following table illustrates this per share dilution:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
    EarthLink is an ISP that was formed to help users derive meaningful benefits
from the extensive resources of the Internet. The Company began offering its
services in July 1994. Since inception, the growth in the Company's customer
base along with an expansion of service offerings has resulted in significant
increases in revenues and related expenses. As a result, period-to period
comparisons of the Company's results of operations may not be as meaningful as
these comparisons would be for mature companies.
 
    The Company's standard EarthLink Network service provides unlimited Internet
access for a one-time registration fee of $25.00 and a flat monthly fee of
$19.95, which is generally collected from a pre-authorized credit card account.
In addition to its standard service, the Company offers a number of premium,
add-on and other services which can increase the speed of, or add features to,
the capabilities of the standard service. Prices and billing methods for
premium, add-on and other services vary. See "Business -- EarthLink's Services."
 
    The Company has experienced net losses since it commenced operations and had
net losses of approximately $6.3 million from inception through 1995 and of
approximately $11.7 million for the six months ended June 30, 1996. As of June
30, 1996, the Company had an accumulated deficit of approximately $16.7 million
(exclusive of $1.3 million of losses incurred while the Company was an S
Corporation for tax purposes, which, upon the Company's conversion to C
Corporation status in June 1995, were charged to the Company's capital
accounts). The Company expects that it will continue to incur net losses as it
continues to expend substantial resources on sales, marketing and
administration, build its infrastructure, develop new service offerings and
improve its management information systems. There can be no assurance that the
Company will achieve or sustain profitability or positive cash flow from its
operations.
 
    The Company's principal strategy is to rapidly expand and retain its
customer base. To realize this strategy, the Company intends to increase its
investment in sales and marketing. Also, the Company plans to add administrative
infrastructure, increase customer and technical support capability and build
network infrastructure to meet customer demand. The sales and marketing and
other costs to the Company of acquiring new customers are substantial relative
to the monthly fee derived from such customers. Accordingly, the Company's
long-term success depends largely upon its ability to retain its existing
customers, while continuing to attract new customers.
 
    The market for the Company's services has only recently begun to develop, is
rapidly evolving and is characterized by an increasing number of market entrants
who have introduced new services for access to the Internet. The Company and its
prospects must be considered in light of the risks, expenses and difficulties
frequently encountered by companies in the new and rapidly evolving market for
Internet services and products. To address these risks, the Company must, among
other things, continue to attract, retain and motivate qualified persons, and
continue to upgrade its infrastructure, including its information systems,
technologies and services. There can be no assurance that the Company will be
successful in addressing such risks. See "Risk Factors."
 
RESULTS OF OPERATIONS
 
    REVENUES.  Recurring revenues consist of monthly fees charged to customers
for Internet access and other ongoing services. Other revenues generally
represent one-time setup fees. Recurring revenues are recognized over the period
for which the services are performed.
 
    For the period from inception, May 26, 1994, through December 31, 1994 (the
"Inception Period") and the year ended December 31, 1995, recurring revenues
were approximately $53,000 and $2.4 million, respectively. Other revenues for
the same periods were approximately $58,000 and $606,000, respectively.
Recurring revenues were approximately $426,000 and $7.6 million for the six
months ended June 30, 1995 and June 30, 1996, respectively. Other revenues were
approximately $192,000 and $2.5 million for the six
 
                                       19
<PAGE>
months ended June 30, 1995 and June 30, 1996, respectively. The increase in
recurring revenues in 1995 as compared to the Inception Period is primarily
attributable to the Company being operational for the full year in 1995 and an
increase in the number of customers during that period. Revenues for the six
months ended June 30, 1996 increased over revenues for the six months ended June
30, 1995 as a result of an increase in the number of customers. The increase in
other revenues for 1995 as compared to the Inception Period is primarily
attributable to an increase in the number of customers added in 1995 and
one-time set-up fees collected from customers. Other revenues for the six months
ended June 30, 1996 increased over other revenues in the six months ended June
30, 1995 as a result of an increase in the number of new customers during that
period and one-time set-up fees collected from customers. From time to time, the
Company waives the one-time set-up fee it charges new customers.
 
    COST OF REVENUES.  Cost of revenues consists of cost of recurring revenues
and cost of other revenues. Cost of recurring revenues principally includes
telecommunications expenses and depreciation expense on equipment used in
network operations for ongoing customer services. Included in telecommunications
cost are fees paid to UUNET for local access to its nationwide system of POPs.
Cost of other revenues principally includes expenses related to the registration
of new customers. These costs include licensing fees for software, software
duplication costs and commissions paid to third parties for referring new
customers to the Company.
 
    For the year ended December 31, 1995, cost of recurring revenues increased
to approximately 44% of recurring revenues, up from 8% of recurring revenues for
the Inception Period. This increase was due to increased hourly customer usage
and the Company's expansion of its POP sites. Cost of recurring revenues for the
six months ended June 30, 1996 increased to approximately 73% of recurring
revenues, up from 60% of recurring revenues for the six months ended June 30,
1995 due to increased hourly customer usage and the Company's expansion to
nationwide service through its relationship with UUNET. During these periods,
the Company paid UUNET a fixed monthly fee per customer plus a variable amount
based on customer usage in excess of a threshold number of hours per month. The
Company's agreement with UUNET was amended as of October 1996 such that the key
variable component is peak usage rather than hourly usage. As the Company
continues to expand, the Company anticipates that it may build and use
additional Company-owned POPs in those geographical areas where there is a
sufficient concentration of customers to support the cost of such investment.
 
    The Company's customers generally pay a fixed monthly fee for the Company's
Internet services. Under the Company's current agreement with UUNET, the Company
pays UUNET a monthly fee equal to the greater of a specified minimum or an
amount that varies based primarily on peak customer usage. The Company also pays
UUNET an additional fee to the extent that hours of usage exceed a formula set
forth in the agreement. The Company has recently experienced increasing per
customer usage of its services. If the number of hours used by EarthLink
customers accessing the Internet through UUNET increases beyond the amount
provided for in the agreement, the fees paid to UUNET would increase, which
would adversely affect the Company's operating margins.
 
    As noted above, under the Company's current agreement with UUNET, the
Company pays UUNET a monthly fee equal to the greater of a specified minimum or
an amount that varies based primarily on peak customer usage. The specified
minimum amount increases over the term of the agreement. The Company's operating
margins could be adversely affected if the Company is unable to increase its
customer base so as to avoid paying the increasing minimum amount. See "Business
- -- EarthLink's Services" and "-- Customers, POPs and Network Infrastructure."
 
    SALES AND MARKETING.  Sales and marketing expenses consist primarily of
sales commissions, salaries, cost of promotional material, advertising, travel
and third-party sales commissions. Sales and marketing expenses were
approximately $37,000, or 33% of revenues, and $3.7 million, or 123% of
revenues, for the Inception Period and the year ended December 31, 1995,
respectively. Sales and marketing expenses were approximately $510,000, or 83%
of revenues, and $5.5 million, or 54% of revenues, for the six months ended June
30, 1995 and June 30, 1996, respectively. These period-to-period increases have
primarily resulted from increased emphasis on marketing the Company's services,
expanding sales and marketing efforts nationwide, increased
 
                                       20
<PAGE>
sales commissions and increased marketing personnel. The Company intends to
aggressively promote EarthLink's services and as a result expects further
significant increases in sales and marketing expenses in future periods. The
Company does not capitalize costs associated with the acquisition of customers.
 
    GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
consist primarily of costs associated with the finance and accounting and human
resources departments, legal expenses, rent and expenses, principally
compensation, related to certain executive officers. General and administrative
expenses were approximately $168,000 and $2.1 million for the Inception Period
and the year ended December 31, 1995, respectively. General and administrative
expenses were approximately $509,000 and $4.1 million, for the six months ended
June 30, 1995 and June 30, 1996, respectively. Since inception, general and
administrative expenses have increased as a result of increased employee
headcount, rent and other general and administrative expenses as the Company
focused on building an administrative infrastructure to accommodate anticipated
increases in the number of customers and employees. During the six months ended
June 30, 1996, the Company hired a number of senior management personnel and
moved into a new headquarters building, which resulted in a significant increase
in general and administrative expenses as compared to the same period in 1995.
Management intends to implement new management information systems and continue
to expand staff in order to support anticipated customer and operational growth.
As a result, the Company expects general and administrative expenses to increase
in future periods.
 
    OPERATIONS AND CUSTOMER SUPPORT.  Operations and customer support expenses
consist primarily of expenses associated with technical support and customer
service to register and maintain customer accounts. Operations and customer
support expenses were approximately $38,000, or 34% of revenues, and $1.9
million, or 62% of revenues, for the Inception Period and the year ended
December 31, 1995, respectively. Operations and customer support expenses were
approximately $384,000, or 62% of revenues, and $5.2 million, or 51% of
revenues, for the six months ended June 30, 1995 and June 30, 1996,
respectively. These expenses have increased significantly since the Company's
inception. This trend reflects the costs associated with building a customer
service organization to support the Company's customer base and anticipated
customer growth. The Company intends to continue to increase expenditures for
operations and customer support.
 
    INCOME TAXES.  No provision for federal or state income taxes has been
recorded as the Company incurred net operating losses through December 31, 1995.
At December 31, 1995, the Company had net operating loss carryforwards for
federal income tax purposes of approximately $3.3 million, which begin to expire
in 2010, and for state income tax purposes of approximately $1.7 million, which
begin to expire in 2001. The Tax Reform Act of 1986 includes provisions that
limit the net operating loss carryforwards for use in a given year if
significant ownership changes have occurred. The Company expects that this
Offering will result in an ownership change limiting the Company's ability to
utilize net operating loss carryforwards to offset future income, if any. The
Company has provided a full valuation allowance on the deferred tax asset
because of the uncertainty regarding realizability. Prior to July 1995, the
Company was taxed as an S Corporation under the Internal Revenue Code. As a
result, losses totaling approximately $2.8 million flowed directly to the
stockholders during the period and are not included in the amount of net
operating loss carryforwards.
 
POTENTIAL FLUCTUATIONS IN QUARTERLY RESULTS
 
    The Company's operating results may fluctuate significantly in the future as
a result of a variety of factors, many of which are beyond the Company's
control. These factors include the rates of, and costs associated with, new
customer acquisition, customer retention, capital expenditures and other costs
relating to the expansion of operations, including upgrading the Company's
systems and infrastructure, the timing and market acceptance of new and upgraded
service introductions, changes in the pricing policies of the Company and its
competitors, changes in operating expenses (including telecommunications costs),
personnel changes, the introduction of alternative technologies, the effect of
potential acquisitions, increased competition in the Company's markets and other
general economic factors. In addition, a significant portion of the Company's
expenses are fixed; therefore, the Company's operating margins are particularly
sensitive to fluctuations in revenues.
 
                                       21
<PAGE>
    In May 1996, the Company entered into an agreement with NMC, a producer of
infomercials and commercials, pursuant to which NMC agreed to produce and
broadcast 15-second and 60-second commercials for EarthLink's services. Under
this agreement, for customers who, in response to these commercials, subscribe
to and pay for the Company's services for 60 days from the date of registration,
the Company is obligated to pay NMC, at NMC's one-time election made prior to
the first airing of any such commercials, either a $45.00 per customer fee or
fees equal to 7% of all revenues received from such customers for five years
from their registration. In addition, the Company agreed to issue warrants to
NMC to purchase up to 100,000 shares of Common Stock, having an exercise price
of $4.88 per share, upon the completion by NMC, subject to the Company's
approval, of the 15-second and 60-second commercials, and to issue warrants to
NMC to purchase one share of Common Stock for each customer generated by this
relationship, up to 600,000 shares of Common Stock. The exercise price of such
additional warrants earned through December 31, 1997 will be $4.88 per share,
and thereafter the exercise price will be the fair market value of the Common
Stock on the date of grant. Upon issuance of any such warrants, the Company will
be required to record in the quarter in which such warrant is issued a non-cash
charge against earnings in an amount equal to the fair value of the warrant on
the date of issuance.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The Company has not generated net cash from operations since its inception.
The Company has funded its operations primarily through private sales of equity
securities, borrowings from third parties and capital leases of equipment. The
Company's operating activities used net cash of approximately $3.6 million and
$7.1 million during 1995 and the six months ended June 30, 1996, respectively.
During 1995 and the six months ended June 30, 1996, net cash used in operations
resulted primarily from net losses, partially offset by increases in trade
accounts payable.
 
    Cash used by investing activities has consisted primarily of equipment
purchases for POP and network expansion. For the year ended December 31, 1995
and the six months ended June 30, 1996, capital expenditures amounted to
approximately $2.8 million and $9.6 million, respectively. Including the $9.6
million spent during the first six months of 1996, the Company anticipates
investing approximately $20.0 million during 1996 on network enhancements,
including leasehold improvements and investments in network equipment.
 
    Cash from financing activities provided the Company with approximately $8.2
million and $16.6 million during 1995 and the six months ended June 30, 1996,
respectively. The Company's financing activities have consisted of the private
sale of debt and equity securities and capital lease transactions, primarily for
equipment. From inception through June 30, 1996, the Company raised $15.1
million through the private sale of debt and equity securities and $7.6 million
relating to capital lease obligations, respectively.
 
    As of December 31, 1995 and June 30, 1996, the Company had cash and cash
equivalents of approximately $290,000 and $1.2 million, respectively, and
negative working capital of approximately $2.0 million and $9.0 million,
respectively. During the second quarter of 1996, the Company received short-term
debt financing (issued in the form of 10% Promissory Notes that mature in June
1997) of $2,950,000 from a limited number of investors, including certain
directors and existing stockholders. As additional consideration for this
investment, EarthLink issued warrants to purchase 196,670 shares of Common Stock
having an exercise price of $5.50 per share. Also during the third quarter of
1996, the Company sold 2,727,723 shares of Series A Convertible Preferred Stock
to a limited number of investors, including certain directors, existing
stockholders, the Underwriter and certain of its affiliates and associates for
$15 million in the aggregate, or $5.50 per share. In connection with this
financing, the Company issued to certain of the investors warrants to purchase
up to 200,000 shares of Common Stock at an exercise price of $5.50 per share.
Each share of Series A Convertible Preferred Stock will automatically convert
into one share of Common Stock upon the consummation of this Offering. See
"Certain Transactions."
 
    In connection with an amendment of its strategic network services
relationship with UUNET, in October 1996, the Company issued a $5 million,
one-year promissory note to UUNET. This note bears
 
                                       22
<PAGE>
interest at prime plus 2% per annum and is convertible into up to approximately
765,000 shares of Common Stock at a conversion price of between $6.60 and $8.00
per share, depending upon the number of shares of Common Stock, if any,
purchased in this Offering by certain investors referred to in the preceding
paragraph and the public offering price of the Common Stock in this Offering.
See "Certain Transactions."
 
    EarthLink expects to use the net proceeds of this Offering to finance sales
and marketing activities, leasehold improvements, investments in network
equipment, information systems, office equipment and new service introductions,
and for working capital and other general corporate purposes. The Company
intends to use a portion of the net proceeds of this Offering to repay
approximately $2.95 million of short-term indebtedness. The Company also intends
to use a portion of the net proceeds of this Offering to repay its outstanding
convertible debt to UUNET, unless UUNET decides to convert such debt to Common
Stock prior to repayment. The Company also anticipates that it may use a portion
of the net proceeds to acquire complementary products and service lines,
technology, equipment, other companies or interests in other companies. While
the Company from time to time has engaged in preliminary discussions concerning
possible acquisitions, investments or joint ventures, it has no present
understandings, commitments, agreements or active negotiations with respect to
any such transaction. See "Certain Transactions."
 
    Pending such uses, the net proceeds of this Offering will be invested in
short-term, investment grade, interest-bearing securities. The Company believes
that the net proceeds from this Offering, together with other available cash
will be sufficient to meet the Company's operating expenses and capital
requirements for at least the next 12 months. However, the Company's capital
requirements depend on numerous factors, including the rate of market acceptance
of the Company's services, the Company's ability to maintain and expand its
customer base, the rate of expansion of the Company's network infrastructure,
the level of resources required to expand the Company's marketing and sales
organization, information systems and research and development activities, the
availability of hardware and software provided by third-party vendors and other
factors. The timing and amount of such capital requirements cannot accurately be
predicted. If capital requirements vary materially from those currently planned,
the Company may require additional financing sooner than anticipated. The
Company has no commitments for any additional financing, and there can be no
assurance that any such commitments can be obtained on favorable terms, if at
all. Any additional equity financing may be dilutive to the Company's
stockholders, and debt financing, if available, may involve restrictive
covenants with respect to dividends, raising future capital and other financial
and operational matters. If the Company is unable to obtain additional financing
as needed, the Company may be required to reduce the scope of its operations or
its anticipated expansion, which could have a material adverse effect on the
Company.

OVERVIEW
 
    EarthLink is an ISP that was formed to help users derive meaningful benefits
from the extensive resources of the Internet. The Company focuses on providing
access, information, assistance and services to its customers to encourage their
introduction to the Internet and to help them have a satisfying user experience.
 
    The Company provides its services through its EarthLink Network TotalAccess
software package, which is designed to simplify access to the Internet through
an online registration feature and a "point and click" graphical user interface.
This software permits users to browse the Internet through use of Netscape
Navigator or Microsoft Explorer (one or the other of which is included in each
copy of TotalAccess), or any other third-party browser that a customer may wish
to use. The Company also provides useful information to its users through its
extensive World Wide Web site. On this site, a user can find technical
assistance information, an on-line newsletter, links to numerous popular
categories of information and entertainment and many other items and services
designed to enhance users' satisfaction with their Internet experience. In
addition, the Company provides a monthly printed newsletter to its customers, a
booklet entitled "Getting the Most Out of EarthLink" and 24 hour customer and
technical support.
 
    The Company markets its services through print advertisements, an affinity
marketing program, a customer referral program and other marketing activities.
Its affinity marketing programs include relationships with, among others,
prominent print publication, software and hardware companies. Customer referrals
have also been an important source of new customers, and the Company provides
economic incentives to its customers, to encourage referrals.
 
    EarthLink also offers business services, including business Web sites,
high-speed ISDN communications capability in Southern California and frame relay
connectivity. In addition, the Company offers consumer services such as
multiplayer Internet games and the EarthLink online store.
 
INDUSTRY BACKGROUND
 
    The Internet is a collection of computer networks linking millions of public
and private computers around the world. Historically, the Internet was used by
government agencies and academic institutions to exchange information, publish
research and transfer email. A number of factors, including the proliferation of
communication-enabled personal computers, the availability of intuitive
graphical user interface software and the wide accessibility of an increasingly
robust network infrastructure, have combined to allow users to easily access the
Internet and, in turn, have produced rapid growth in the number of Internet
users. International Data Corporation estimates that the number of Internet
users was approximately 56 million at the end of 1995 and that this number will
reach approximately 200 million by the end of 1999.
 
    The emergence of the World Wide Web, the graphical, multimedia environment
of the Internet, has resulted in the development of the Internet as a new mass
communications medium. The ease and speed of publishing, distributing and
communicating text, graphics, audio and video over the Internet has led to a
proliferation of Internet-based services, including chat, online magazines, news
feeds, interactive games and a wealth of educational and entertainment
information, as well as to the development of online communities. In addition,
the reduced cost of executing transactions over the Internet provides
individuals and organizations with a new means to conduct business.
 
STRATEGY
 
    The principal components of EarthLink's growth strategy are as follows:
 
    RAPIDLY EXPAND ITS CUSTOMER BASE.  EarthLink believes that a key to success
in the competitive ISP market is to expand its customer base as rapidly as
possible to establish a significant revenue base, thereby enhancing its ability
to enter into favorable arrangements with affinity marketing partners and
providers of content, network access and software enhancements. The Company
plans to devote significant effort and financial
 
                                       24
<PAGE>
resources on sales and marketing. The Company plans to continue print
advertising in major computer magazines, expand its radio advertising program,
seek to expand its affinity marketing program, maintain a presence at national,
regional and local trade shows and continue to offer economic incentives to
customers who refer new customers.
 
    RETAIN THE COMPANY'S EXISTING CUSTOMERS.  The sales, marketing and other
costs to the Company of acquiring new customers are substantial relative to the
monthly fee derived from such customers. Accordingly, the Company believes that
its long-term success largely depends on maintaining customer satisfaction with
its services. Therefore, EarthLink plans to devote significant resources to
enhancing its network operations capability, its World Wide Web site and its
service offerings. In addition, the Company will continue to expand its
technical support staff and enhance the staff's effectiveness by providing
software tools that can assist it in identifying and solving customer problems.
 
    DEVELOP ADDITIONAL SERVICE OFFERINGS.  EarthLink recognizes that the
introduction of additional service offerings can serve not only to expand and
maintain its customer base, but also, in certain instances, to enhance revenues.
Accordingly, the Company has introduced a variety of services for business
consumers, including business Web sites, high-speed ISDN communications
capability (presently offered in Southern California only) and frame relay
connections, each of which involve a monthly service charge plus set-up fees.
The Company also plans to expand its service offerings for consumers, including
personalized start pages, chat and multiplayer Internet games.
 
    FOCUS ON CUSTOMER NEEDS.  EarthLink seeks to help its customers derive
meaningful benefits from the extensive resources of the Internet. In order to
maintain its focus on customer needs, the Company has leveraged the
infrastructure and software development efforts of others by leasing POP
capacity from UUNET (and, in the future, PSINet) and licensing software from
software developers. The Company believes that this approach gives it
flexibility to rapidly expand its service coverage without the need for
substantial capital expenditures. The Company will continue to pursue this
strategy so that, in addition to its sales and marketing efforts, it can devote
its principal resources to improving its customers' experience with the
Internet.
 
EARTHLINK'S SERVICES
 
    EarthLink provides a variety of competitively-priced Internet services to
consumer and business customers. The Company makes these services available
through its EarthLink Network TotalAccess software package. This software
incorporates a telephone dialer and email functionality with several leading
third-party Internet access tools, including either Netscape Navigator or
Microsoft Explorer, thereby providing a functional, easy-to-use Internet access
solution for Windows 3.1, Windows 95 and Macintosh platforms. EarthLink Network
TotalAccess installation software automatically installs these and other
software applications on the customer's computer. The simple point-and-click
functionality of EarthLink Network TotalAccess, combined with its easy-to-use
registration module, permits online credit card registration, allowing new
EarthLink customers to quickly access the Internet.
 
    The prices quoted below are subject to change.
 
    STANDARD EARTHLINK NETWORK INTERNET SERVICES.  EarthLink provides its
customers with a core set of features through its standard Internet service,
which provides unlimited access to the Internet as well as the other features
and services for a flat monthly fee of $19.95 and a one-time setup fee of $25.
The following functionalities are included in the standard EarthLink service:
 
    INTERNET ACCESS.  EarthLink provides customers with direct high-speed access
to the Internet and the Web in a manner that is designed to be reliable and easy
to use.
 
    EARTHLINK NETWORK WEB SITE.  EarthLink has developed and maintains its own
Web site containing EarthLink content and links to third-party content.
EarthLink's in-house staff actively seeks out interesting content from across
the Internet and categorizes it into subject areas of interest organized on the
EarthLink Web site under topics such as "What's Hot," "Hollywood," "News,"
"Finance" and "Games." The Company's Web site provides a road map to volumes of
information and services available on the Internet. A user can
 
                                       25
<PAGE>
browse the site and click on topics of interest in order to link to desired
information. In addition, through search engines and the embedded functionality
of Netscape Navigator or Microsoft Explorer, a user can conduct customized
searches for other topics.
 
    EMAIL.  Each customer is provided a mailbox, or address, from which to send
and receive email. Email functionality allows customers to exchange an unlimited
number of multimedia text, graphics, audio and video messages with other
EarthLink customers as well as with non-EarthLink Internet users.
 
    PERSONAL WEB SITES.  Each EarthLink customer is provided two megabytes of
disk space on the Company's Web server to create his or her own Web home page.
This enables each customer to participate in the Internet community by
personally adding content to the World Wide Web.
 
    PUBLICATIONS.  EarthLink publishes BLINK-TM-, a monthly newsletter, which it
mails to each of its customers. Through this publication, the Company provides
its customers with useful information, such as tips on how to search for certain
categories of information on the Internet and information regarding new
EarthLink service offerings, new Internet sites and other items of interest.
This publication is also available as an online feature, updated daily, on the
EarthLink home page. Additionally, the Company's founder, Sky Dayton, has
authored and published a booklet entitled "Getting the Most Out of EarthLink,"
which the Company provides its new customers subscribing through dial-up sales
and provides to all other customers upon request.
 
    CHAT.  Chat enables customers to "talk" with one another in typed text in
real time, one-on-one or in groups known as chat rooms.
 
    PREMIUM EARTHLINK NETWORK SERVICES.  In addition to its standard service,
the Company offers a variety of premium services, including the following:
 
    BUSINESS WEB SITES.  The Company provides space on its Web server for
commercial customers to publish their own Web pages. Monthly fees for business
Web sites range from $89 to $439, plus one-time setup fees of $179 to $479,
depending on the size of the site and whether the site is a shared or unique
address. Each option is also available with an audio feature for an additional
charge. Additional charges, based on the volume of users accessing a site, may
apply.
 
    ISDN CAPABILITY.  EarthLink offers high-speed ISDN Internet access
communication lines for its Southern California business customers. ISDN
provides a faster, more efficient method for communicating digital data over
telephone lines. ISDN speeds are up to four times faster than conventional modem
speeds (up to 128 Kbps versus up to 33.6 Kbps). ISDN service charges range from
$45 to $249 per month depending on access speeds, connect time and other data
transfer metrics. One-time setup fees range from $50 to $495. The Company
anticipates offering ISDN service on a nationwide basis in the near future.
 
    FRAME RELAY CAPABILITY.  Frame relay enables direct, high-speed continuous
connection of an organization's internal local area network to the Internet
using dedicated circuits at speeds ranging from 56 Kbps to 1,544 Kbps. This
service enables businesses to connect an entire local area network or high-end
workstation to the Internet and provides the fastest data transfer rate
generally available. Frame relay service fees range from $495 to $995 per month
depending on access speeds, data throughput and other data transfer metrics.
One-time setup fees range from $745 to $1,245.
 
    MULTIPLAYER INTERNET GAMES.  The Company recently introduced The Arena, a
multi-player Internet games service that allows EarthLink and non-EarthLink
users to play multimedia games through the EarthLink Network for an hourly fee.
The Company creates an incentive for non-EarthLink users to subscribe to
EarthLink by charging them a slightly higher fee to participate in The Arena.
 
    SUPPLEMENTAL SERVICES.  To augment its standard and premium services, the
Company provides its customers with the following supplemental services:
 
    ADDITIONAL MAILBOXES.  The Company provides additional mailboxes for a per
mailbox setup fee of $9.95 and a monthly service fee of $4.95 for those
customers who require more than one mailbox for colleagues, employees or family
members.
 
                                       26
<PAGE>
    DOMAIN NAME REGISTRATION.  EarthLink provides unique domain names for those
customers who prefer an individualized address. Instead of
"[email protected]," the user Joe Smith may prefer the name "[email protected]."
Or a business user may find greater marketing presence by having a domain name
in the name of his business, such as "[email protected]." EarthLink charges $75 to
assist in establishing unique domain names for customers. Customers then pay an
annual renewal fee to an Internet domain registration agency.
 
    800 SERVICE.  EarthLink provides 800 number dial-up service for customers
who do not have access to a local POP. EarthLink charges customers $24.95 per
month for five hours of 800 number service plus a one-time setup fee of $25.00.
Additional hours are $4.95 per hour.
 
TECHNICAL DEVELOPMENT AND SERVICE ENHANCEMENT
 
    EarthLink places significant emphasis on expanding and refining its services
to enhance its customers' Internet experience. EarthLink's technical staff is
engaged in a variety of technical development and service enhancement
activities, including improvement of the functionality of the Company's
EarthLink Network TotalAccess software and reviewing new third-party software
products for potential incorporation into TotalAccess. EarthLink also regularly
updates and expands the online services provided through the EarthLink Web site.
These activities include organizing Web content and the development of online
guides, help screens and other user services.
 
    The Company anticipates the near-term release of the following services:
 
    PERSONALIZED START PAGE.  When customers "sign on" to EarthLink, they
generally begin their Internet session at the EarthLink home page and proceed
from there to the other sites and services of their choice. A "personalized
start page," which the Company plans to introduce in late 1996, will allow
customers to customize the page that first appears when they log on to the
EarthLink Network. For example, a customer may include short-cuts to favorite
Web sites, find advertisements targeted to the customer's interests
automatically displayed, change the "look and feel" of the start page and
otherwise tailor the start page to accomodate his or her personal preferences.
 
    PREMIUM SERVICE OFFERINGS.  The Company is engaged in ongoing efforts to
provide its customers with access to premium services, such as the Wall Street
Journal online newspaper and the ESPN sports service. The Company intends to
bundle these third-party premium services in packages and offer them to its
customers at discounted rates. These services will be billed directly to the
user's EarthLink account rather than separately by the provider of the premium
services, and will not require EarthLink customers to establish separate user
names and passwords to access the premium services.
 
    ONLINE COMMERCE.  The Company recently opened the EarthLink online store,
which offers EarthLink branded merchandise that online shoppers may purchase by
placing an order through the EarthLink Network via an online credit card
transaction. The Company intends to further develop its systems for offering
electronic retail services by establishing an online mall through which it can
"lease space" to businesses to advertise and sell their products and services.
 
MARKETING
 
    As of September 30, 1996, the Company marketed and sold its services through
its sales and marketing department comprised of 82 employees. EarthLink's sales
and marketing efforts consist of the following programs:
 
    ADVERTISING.  The Company advertises its services in print media and on
radio. Included in the advertisement is a toll-free 800 number to contact the
Company's internal sales staff. When a potential customer calls the Company's
sales staff, the customer is assigned a user name and password. Subsequently,
the new customer is sent a copy of EarthLink Network TotalAccess, which the
customer uses to log on to the Company's system.
 
                                       27
<PAGE>
    AFFINITY MARKETING PROGRAM.  EarthLink's affinity marketing program promotes
the Company through the distribution of the EarthLink Network TotalAccess
software package by its affinity marketing partners. These partners typically
bundle EarthLink Network TotalAccess disks with their own goods or services.
Marketing partners include MacMillan Publishing USA, Activision, Inc., Micro
Warehouse Incorporated, Adobe Systems, Inc., United Airlines, Inc., Iomega
Corp., CompUSA, Inc. and Best Buy Co., Inc.
 
    A significant number of EarthLink's customers have been generated through
its relationships with its affinity marketing partners, and the Company believes
that its affinity marketing relationships will continue to account for a
significant number of new customers. There can be no assurance, however, that
the Company's current affinity marketing partners will continue to distribute
the Company's software or will continue to generate new customers for the
Company's services. The Company's inability to maintain its affinity marketing
relationships or establish new affinity marketing relationships could result in
delays and increased costs in expanding its customer base, which could, in turn,
have a material adverse effect on the Company.
 
    CUSTOMER REFERRAL PROGRAM.  The Company believes that one of its most
important marketing tools is its existing customers. In order to encourage
customers to refer other users, the Company currently provides an incentive of
$19.95 credited to their account (equivalent to the standard monthly access fee)
per referred customer.
 
    OTHER MARKETING ACTIVITIES.  EarthLink maintains a presence at national
trade shows such as Comdex, MacWorld and OnLine Expo, as well as local and
regional trade shows. Additionally, the Company markets through computer,
Internet and related publications, and bundles EarthLink Network TotalAccess
with a few of these publications, either as disks that contain only the
EarthLink Network TotalAccess software package or as CD-ROMs that may include
numerous other software applications. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations -- Potential Fluctuations in
Quarterly Results" for additional information concerning a marketing agreement
with NMC.
 
CUSTOMERS, POPS AND NETWORK INFRASTRUCTURE
 
    As of the end of September 1996, the Company had approximately 186,000
customers.
 
    The Company presently provides its customers with Internet access primarily
through UUNET's nationwide system of POPs. Substantially all of the Company's
customers access the EarthLink Network and the Internet by dialing into local
POPs. Of these, the Company owns 20 POP sites in California and currently offers
additional access through 336 UUNET POPs, to which it has access on a
non-exclusive basis. The Company's POP network, as of October 31, 1996, is set
forth below.
 
                                       28
<PAGE>
                                  [MAP]
 
    Not reflected on this map are the approximately 350 POPs maintained by
PSINet, through which the Company has agreed to lease POP capacity on a
non-exclusive basis, which the Company anticipates becoming accessible to its
customers during the fourth quarter of 1996. The Company is dependent on UUNET
(and in the future may also be dependent on PSINet) to continue to provide the
Company's customers with access to the Internet through its system of POPs. The
inability or unwillingness of either or both of these third-party network
providers to permit POP access to EarthLink's customers, or the Company's
inability to secure alternative POP arrangements, could have a material adverse
effect on the Company. See "Risk Factors -- Dependence on Third-Party Network
Providers" and "Risk Factors -- Dependence on Network Infrastructure; Capacity;
Risk of System Failure; Security Risks."
 
    For customers located in a geographic area not presently serviced by a local
POP, the EarthLink Network can be accessed by a toll-free number for which the
Company bills customers on an hourly usage basis. The Company's POP sites are
connected to the Internet primarily through its network hub in Los Angeles. The
Company's network hub is in turn connected directly to the Internet via leased
high-speed fiber optic data lines. The Company intends to relocate its network
hub from Los Angeles to Pasadena. See "-- Facilities" and "Risk Factors --
Dependence on Network Infrastructure; Capacity; Risk of System Failure; Security
Risks."
 
    The Company does not presently maintain redundant or backup Internet
services or backbone facilities or other redundant computing and
telecommunication facilities. Any accident, incident or system failure that
causes interruptions in the Company's operations could have a material adverse
effect on the Company's ability to provide Internet services to its customers,
and, in turn, on the Company.
 
CUSTOMER AND TECHNICAL SUPPORT
 
    The Company believes that reliable customer and technical support is
critical to retaining existing and attracting new customers. The Company
currently provides the following types of customer and technical support: (i)
toll-free, live telephone assistance available seven days a week, 24 hours a
day; (ii) email-based
 
                                       29
<PAGE>
assistance available seven days a week, 24 hours a day; (iii) help sites and
Internet guide files on the EarthLink Web site; (iv) automated "fax back" and
"fax on demand" assistance; and (v) printed reference material. Additionally,
the Company provides dedicated support for its business customers.
 
    In order to continue to improve its support services and to deliver those
services in a more timely and cost-effective manner, the Company is currently
expanding its call center facilities and installing new call management database
software. The Company also intends to purchase new call center hardware and
software. The Company has expanded its support staff from 81 employees as of
December 31, 1995 to 211 employees as of September 30, 1996.
 
    The Company's growth has placed, and is expected to continue to place, a
significant strain on its managerial, operational, financial and information
system resources. Demand on the Company's network infrastructure, technical
staff and resources has grown rapidly with the Company's expanding customer
base, and the Company has experienced difficulties satisfying the demand for its
Internet services. There can be no assurance that the Company's infrastructure,
information systems, technical staff and resources will be adequate to
facilitate the Company's growth. See "Risk Factors -- Risks Associated with
Management of Potential Growth."
 
SUPPLIER RELATIONSHIPS
 
    The Company is dependent on certain third-party suppliers of hardware
components. Certain components used by the Company in providing its network
services are currently acquired from limited sources. The Company also depends
on third-party software vendors to provide the Company with much of its Internet
software, including Netscape Navigator and Microsoft Explorer, the World Wide
Web browser software that the Company licenses from Netscape and Microsoft,
respectively. Failure of the Company's suppliers to provide components and
products in the quantities, at the quality levels or at the times required by
the Company, or an inability by the Company to develop alternative sources of
supply if required, could adversely affect the Company's ability to effectively
support the growth of its customer base in a timely manner and result in delays
in and increase its costs of expansion. Moreover, because Netscape Navigator and
Microsoft Explorer are the two most widely used Web browsers, the failure of
Netscape or Microsoft to continue to provide World Wide Web browser software to
the Company could have a material adverse effect on the Company.
 
COMPETITION
 
    The Internet services market in which the Company operates is extremely
competitive, and the Company expects competition in this market to intensify in
the future. The Company's current and prospective competitors include many large
companies that have substantially greater market presence and financial,
technical, marketing and other resources than the Company. The Company competes
(or in the future is expected to compete) directly or indirectly with the
following categories of companies: (i) national and regional ISPs, such as BBN,
IDT, MindSpring, NETCOM, PSINet and UUNET; (ii) established online services such
as America Online, CompuServe, Prodigy and the Microsoft Network; (iii) computer
software and technology companies such as Microsoft; (iv) national
telecommunications companies, such as AT&T, MCI and Sprint; (v) RBOCs; (vi)
cable operators, such as Comcast, TCI and Time Warner; and (vii) nonprofit or
educational Internet service providers.
 
    The entry of new participants from these categories and the potential entry
of competitors from other categories (such as computer hardware manufacturers)
will result in substantially greater competition for the Company. The ability of
these competitors or others to bundle services and products with Internet
connectivity services could place the Company at a significant competitive
disadvantage. In addition, competitors in the telecommunications industry may be
able to provide customers with reduced communications costs in connection with
their Internet access services, reducing the overall cost of Internet access and
significantly increasing pricing pressures on the Company. Moreover, certain of
the Company's online competitors, including America Online, the Microsoft
Network and Prodigy, have recently announced unlimited access to the Internet
and their proprietary content at flat rates that are equal to the Company's flat
rate, and do not
 
                                       30
<PAGE>
require a set-up fee. Certain of the RBOCs have also announced competitive
flat-rate pricing for unlimited access (without a set-up fee) for at least some
period of time. As a result, competition for active users of Internet services
should intensify. There can be no assurance that the Company will be able to
offset the adverse effect on revenues of any necessary price reductions
resulting from competitive pricing pressures by increasing the number of its
customers, by generating higher revenue from enhanced services, by reducing
costs or otherwise. See "Risk Factors -- Competition."
 
    The Company believes that its ability to compete successfully in the
Internet services market depends on a number of factors, including market
presence; the adequacy of the Company's customer and technical support services;
the capacity, reliability and security of its network infrastructure; the ease
of access to and navigation of the Internet provided by the Company's services;
the pricing policies of the Company, its competitors and its suppliers; the
timing of introductions of new services by the Company and its competitors; the
Company's ability to support existing and emerging industry standards; and
industry and general economic trends. There can be no assurance that the Company
will have the financial resources, technical expertise or marketing and support
capabilities to compete successfully.
 
PROPRIETARY RIGHTS
 
    GENERAL.  The Company believes that its success is dependent in part on its
technology and its continuing right to use such technology. The Company relies
on a combination of copyright, trademark and trade secret laws and contractual
restrictions to establish and protect its technology. It is the Company's policy
to require employees and consultants and, when possible, suppliers to execute
confidentiality agreements upon the commencement of their relationships with the
Company. There can be no assurance that the steps taken by the Company will be
sufficient to prevent misappropriation of its technology and other proprietary
property or that the Company's competitors will not independently develop
technologies that are substantially equivalent or superior to the Company's
technology.
 
    There can be no assurance that third parties will not assert that
EarthLink's services infringe their proprietary rights. From time to time, the
Company has received communications from third parties alleging that certain of
the names or marks for the Company's services infringe the trademarks of such
third parties. To date, no such claims have had an adverse effect on the
Company's ability to market and sell its services. However, there can be no
assurance that those claims will not have an adverse effect in the future or
that other parties will not assert infringement claims against the Company in
the future with respect to current or future services. Such claims could result
in substantial costs and diversion of resources even if ultimately decided in
favor of the Company and could have a material adverse effect on the Company,
particularly if judgments on such claims are adverse to the Company. In the
event a claim is asserted alleging that the Company has infringed the
intellectual property or information of a third party, the Company may be
required to seek licenses to continue to use such intellectual property. There
can be no assurance, however, that such licenses would be offered or obtained on
commercially reasonable terms, if at all, or that the terms of any offered
licenses will be acceptable to the Company. The failure to obtain the necessary
licenses or other rights could have a material adverse effect on the Company.
 
    LICENSES.  EarthLink has obtained authorization, typically in the form of a
license, to distribute third-party software incorporated in the EarthLink
Network TotalAccess software product for Windows 3.1, Windows 95 and Macintosh
platforms. Applications licensed by the Company include Netscape Navigator (the
initial term of the license for which expires in December 1997 and thereafter
automatically renews for additional one-year terms unless either party
terminates the license on 120 days notice), Microsoft Explorer (the initial term
of the license for which expires in August 1998 and thereafter automatically
renews for additional one-year terms, although either party may terminate the
license at any time on 30 days notice), and MacTCP software from Apple (the
current term of the license for which expires on December 31, 1996 thereafter
and automatically renews for additional one-year terms unless either party
terminates the license on twelve-month notice). The only software in the
EarthLink Network TotalAccess package that is developed by the Company is the
front-end program and the installation/registration program. The Company
currently
 
                                       31
<PAGE>
intends to maintain or negotiate renewals of existing software licenses and
authorizations. The Company may want or need to license other applications in
the future. The failure to renew existing software licenses and authorizations
or license other applications could have a material adverse effect on the
Company.
 
    TRADEMARKS.  "EarthLink Network-Registered Trademark-," "EarthLink Network
TotalAccess-TM-," "bLink-TM-," "The Arena-TM-" and the EarthLink logo are
trademarks of the Company. This Prospectus includes trademarks of companies
other than the Company.
 
GOVERNMENT REGULATION
 
    The Company provides Internet services, in part, through data transmissions
over public telephone lines. These transmissions are governed by regulatory
policies establishing charges and terms for wire line communications. The
Company currently is not subject to direct regulation by the FCC or any other
governmental agency, other than regulations applicable to businesses generally.
However, in the future the Company could become subject to regulation by the FCC
or another regulatory agency as a provider of basic telecommunications services.
For example, a number of long distance telephone carriers recently filed a
petition with the FCC seeking a declaration that Internet telephone service is a
"telecommunications service" subject to common carrier regulation. Such a
declaration, if enacted, would create substantial barriers to the Company's
entry into the Internet telephone market. The FCC has requested comments on this
petition, but has not set a deadline for issuing a final decision.
 
    The recently enacted Telecommunications Act contains certain provisions that
lift, or establish procedures for lifting, certain restrictions relating to the
RBOCs' ability to engage directly in the Internet access business. The
Telecommunications Act also makes it easier for national long distance carriers
such as AT&T to offer local telephone service. In addition, the
Telecommunications Act allows the RBOCs to provide electronic publishing of
information and databases. Competition from these companies could have an
adverse effect on the Company's business. The Telecommunications Act also
imposes fines on any entity that knowingly (i) uses any interactive computer
service or telecommunications device to send obscene or indecent material to
minors; (ii) makes obscene or indecent material available to minors via an
interactive computer service; or (iii) permits any telecommunications facility
under such entity's control to be used for the purposes detailed above. The
standard for determining whether an entity acted "knowingly" has not yet been
established, although a federal district court panel recently issued a
preliminary injunction preventing enforcement of this part of the
Telecommunications Act. This decision may be appealed. See "Risk Factors --
Potential Liability."
 
    Due to the increasing use of the Internet, it is possible that additional
laws and regulations may be adopted with respect to the Internet, covering
issues such as content, user privacy, pricing and copyright and intellectual
property protection and infringement. Changes in the regulatory environment
relating to the Internet access industry, including regulatory changes that
directly or indirectly affect telecommunications costs or increase the
likelihood or scope of competition from regional telephone companies or others,
could have an adverse effect on the Company. See "Risk Factors -- Competition."
 
EMPLOYEES
 
    As of September 30, 1996, the Company employed 480 people on a full-time
basis, including 82 sales and marketing personnel, 30 Web site and content
development personnel, 83 MIS and information technologies personnel, 211
customer and technical support representatives and 74 administrative personnel.
As of that date, the Company also employed 34 people on a part-time basis, most
of whom serve as telephone customer and technical support representatives. None
of the Company's employees are represented by a labor union, and the Company is
not a party to any collective bargaining agreement.

FACILITIES
 
    EarthLink's corporate headquarters are located in an 85,500-square foot
facility in Pasadena, California. The lease for this space expires June 30,
2001. The Company has an option to extend this lease for an additional five
years at the then prevailing market rate. In addition to the Company's corporate
headquarters, the Company also leases approximately 7,200 square feet of office
space in Los Angeles that presently houses the Company's data center. EarthLink
has signed a lease for an additional 55,000 square feet in a facility located
adjacent to its corporate headquarters in which it plans to house its data
center. The Company expects to occupy this new space commencing February 1997
for an initial ten-year term.

     are based on assumed rates of stock price appreciation of 5% and 10%
     compounded annually from the date the respective options were granted to
     their expiration date based upon the fair market value on the date of grant
     as determined by the Board of Directors. These assumptions are not intended
     to forecast future appreciation of the Company's stock price. The potential
     realizable value computation does not take into account federal or state
     income tax consequences of option exercises or sales of appreciated stock.

EMPLOYMENT AGREEMENT
 
    In January 1996, the Company entered into a two-year employment agreement
with Mr. Charles G. Betty. Under this agreement, the Company agreed to employ
Mr. Betty as its President and Chief Operating Officer at a salary of $225,000
per year plus a $24,000 a year travel allowance for Mr. Betty and his family and
such other benefits as are generally made available to other senior executives
of the Company. In May 1996, Mr. Betty was named the Company's Chief Executive
Officer. Mr. Betty is also guaranteed a bonus of at least $37,500 for 1996 and
may earn up to an additional $37,500 for 1996 if the Company has a specified
number of customers by year-end. The agreement provides that (i) if Mr. Betty is
terminated by the Company other than for "cause" or "total disability," as
defined in the agreement, (ii) if the Company elects not to extend the term of
the employment agreement at the end of the first two-year term or any yearly
extension or (iii) if Mr. Betty terminates his employment because of a breach of
the employment agreement by the Company, he is entitled to severance
compensation equal to 100% of his then-current annual salary. In connection with
entering into the employment agreement, Mr. Betty purchased 50,000 shares of the
Common Stock at $2.42 per share, and also was granted options to purchase an
additional 350,000 shares of Common Stock at an exercise price of $2.42 per
share. In addition, in September 1996, Mr. Betty was granted options to purchase
an additional 150,000 shares of Common Stock at an exercise price of $5.50 per
share. All of Mr. Betty's options vest in equal quarterly increments of 5%
during the five-year period beginning on the respective dates of grant, January
15, 1996 and September 24, 1996. In the event of a "change in control," as
defined in the agreement, the termination of Mr. Betty by the Company other than
for cause or if Mr. Betty terminates his employment because of a breach of the
agreement by the Company, all unvested options held by Mr. Betty will vest
immediately.
 
1995 STOCK OPTION PLAN AND OTHER OPTION AND WARRANT ISSUANCES
 
    The EarthLink Network 1995 Stock Option Plan (the "1995 Plan") provides for
the grant of incentive stock options to employees of the Company within the
meaning of Section 422 of the Internal Revenue Code of 1986, as amended, and
non-qualified stock options to employees, officers, directors and consultants of
the Company. The 1995 Plan is administered by the Compensation Committee of the
Board of Directors, which determines the terms of the options granted, including
the exercise price, the number of shares subject to option and the option
vesting period. The exercise price of all options granted under the plan must be
at least 85% of the fair market value (for non-qualified stock options) or 100%
of the fair market value (for incentive stock options) as of the date of grant.
As of September 30, 1996, options to purchase 2,011,500 shares of
 
                                       39
<PAGE>
Common Stock were outstanding under the 1995 Plan. In addition, as of that date
the Company had issued non-plan options and warrants to purchase an aggregate of
2,662,888 shares of Common Stock at exercise prices ranging from $0.30 to $10.00
per share.
 
DIRECTORS STOCK OPTION PLAN AND OTHER DIRECTOR OPTION ISSUANCES
 
    Under the Company's Directors Stock Option Plan (the "Directors Plan"),
options to purchase 125,000 shares of Common Stock may be granted to directors
who do not also serve as employees of the Company. Under the Directors Plan,
grants of options to purchase 20,000 and 5,000 shares of Common Stock are
automatically made to each non-management director at the time such person first
becomes a member of the Board of Directors and at the beginning of each fiscal
year of the Company, respectively. As of September 30, 1996, there were no
options to purchase shares of Common Stock outstanding under the Directors Plan.
 
    Prior to the adoption by the Board of Directors of the Directors Plan, the
Company issued to each of Messrs. Kavner and Lacy warrants to purchase 100,000
shares of Common Stock at an exercise price of $2.42 per share, the amount then
determined by the Board of Directors to constitute fair market value, in
consideration of Messrs. Kavner's and Lacy's agreement to serve on the Board of
Directors. These warrants vest over a five-year period from January 12, 1996,
the date of grant.

                              CERTAIN TRANSACTIONS
 
    Kevin M. O'Donnell and Reed E. Slatkin are members of the Board of Directors
of the Company, and each owns more than five percent of the Company's
outstanding Common Stock. Messrs. O'Donnell and Slatkin have participated in the
Company's financing since inception, as described below.
 
    In December 1994, Messrs. Slatkin and O'Donnell provided a $400,000 credit
line to the Company for which each of them received warrants to purchase 150,000
shares of Common Stock at an exercise price of $0.91 per share, the amount then
determined by the Board of Directors to constitute the fair market value of the
Common Stock. Indebtedness outstanding under this line bore interest at 8.1% per
annum. The maximum amount outstanding under this line was $397,686, which was
repaid in full in September 1995.
 
    In August 1995 and January 1996, Mr. Slatkin agreed to act as lessee
together with the Company under equipment leases of $500,000 and $1.5 million,
respectively. As consideration for this agreement, the Company issued Mr.
Slatkin warrants to purchase 100,000 shares of Common Stock at an exercise price
of $0.91 per share and 200,000 shares of Common Stock at an exercise price of
$2.42 per share, the amount then determined by the Board of Directors to
constitute the fair market value as of August 1995 and January 1996,
respectively. The Company and Mr. O'Donnell subsequently agreed to indemnify Mr.
Slatkin against certain liability arising out of these leases. As consideration
for this agreement, Mr. Slatkin transferred one-half of these warrants to Mr.
O'Donnell.
 
    In December 1995, Mr. Slatkin guaranteed a $250,000 letter of credit as
security for the Company's lease of its Pasadena facility. In return, he
received warrants to purchase 100,000 shares of Common Stock at an exercise
price of $2.42 per share, the amount then determined by the Board of Directors
to constitute the fair market value of the Common Stock. The Company and Mr.
O'Donnell subsequently agreed to indemnify Mr. Slatkin with respect to certain
liability arising out of the letter of credit. As consideration for this
agreement, Mr. Slatkin transferred to Mr. O'Donnell one-half of these warrants.
 
    In addition, the Company and Messrs. Dayton, O'Donnell and Slatkin are
parties to a Buy-Sell Agreement pursuant to which the Company has the first
right of refusal upon sale or transfer of shares of Common Stock by such
persons. The right will expire upon consummation of this Offering. See Note 7 to
Notes to Financial Statements.
 
    From time to time since the Company's inception, the Company's officers,
directors and more than five percent stockholders (including certain of their
family members and affiliates) have purchased shares of Common Stock at the
weighted average per share purchase prices as follows: Gregory Abbott, 677,250
shares, $2.04 per share; Charles G. Betty, 50,000 shares, $2.42 per share; Sky
D. Dayton, 3,000,000 shares, $0.0003 per share; Sidney Azeez, 1,044,916 shares,
$3.13 per share; Linwood A. Lacy, Jr., 49,620 shares, $2.42 per share; Robert M.
Kavner, 41,350 shares, $2.42 per share; Robert London, 744,065 shares, $1.08 per
share; Kevin M. O'Donnell, 1,884,305 shares, $0.42 per share; Reed E. Slatkin,
1,884,315 shares, $0.42 per share; and Storie Partners, L.P., 831,197 shares,
$3.13 per share.
 
    In June 1996, the Company issued $2,950,000 of its 10% Promissory Notes to
17 purchasers, including certain of its directors and more than five percent
stockholders. In connection with this financing, and as additional consideration
for the investment of these purchasers, the Company also issued warrants to
purchase 196,670 shares of Common Stock having an exercise price of $5.50 per
share. The 10% Promissory Notes are due on or before June 6, 1997 with interest
payable monthly until such date. The warrants are exerciseable for five years
commencing on the date of issuance.
 
    The following directors and more than five percent stockholders participated
in this financing: Gregory Abbott, $200,000 note, 13,333 warrants; Sidney Azeez,
$200,000 note, 13,333 warrants; Robert M. Kavner, $100,000 note, 6,667 warrants;
Robert S. London, $200,000 note, 13,333 warrants; Kevin M. O'Donnell, $225,000
note, 15,000 warrants; Reed E. Slatkin, $225,000 note, 15,000 warrants; and
Storie Partners, L.P., $300,000 note, 20,000 warrants.
 
                                       41

    In September 1996, the Company sold 2,727,273 shares of its Series A
Convertible Preferred Stock to certain purchasers, including, among others,
certain directors, stockholders, the Underwriter and certain of its associates
for approximately $15,000,000 in the aggregate. In connection with this
transaction, Quantum Industrial Partners LDC and persons and entities associated
with or employed by Soros Fund Management ("SFM") received warrants to purchase
up to 200,000 shares of Common Stock at an exercise price of $5.50 per share.
Each share of Series A Convertible Preferred Stock will automatically convert
into one share of Common Stock upon the consummation of this Offering.
 
    The following directors and more than five percent stockholders (including
certain of their family members and affiliates) participated in this financing:
Quantum Industrial Partners LDC (1,866,127 shares of Common Stock and 190,600
shares of Common Stock underlying warrants, which includes 429,090 shares of
Common Stock and warrants to purchase 47,200 shares of Common Stock held by
George Soros, who may be deemed to have sole and ultimate control over SFM, in
which Quantum Industrial Partners LDC has vested investment discretion with
respect to its portfolio investments, and 90,910 shares of Common Stock and
10,000 shares of Common Stock underlying warrants held by trusts established for
the benefit of certain children of Mr. Soros); Reed E. Slatkin (78,547 shares);
Gregory Abbott (30,000 shares); Sidney Azeez (30,000 shares); Linwood A. Lacy,
Jr. (20,000 shares); Robert S. London (20,000 shares); Brinton O.C. Young
(20,000 shares); Kevin M. O'Donnell (20,000 shares); and Charles G. Betty
(10,000 shares).
 
    John W. Sidgmore, a member of the Company's Board of Directors, also serves
as a director and Chief Executive Officer of UUNET and as President and Chief
Operating Officer and as a director of UUNET's corporate parent, MFS. UUNET is
the Company's primary provider of POP capacity. In connection with the Company's
and UUNET's execution of a new network services agreement in May 1996, the
Company agreed to issue warrants to UUNET to purchase 20,000 shares of Common
Stock having an exercise price of $10.00 per share.
 
    In connection with an amendment to the Company's network services agreement
with UUNET, the Company issued a $5 million, one-year promissory note to UUNET
and filled a vacancy on the Board of Directors with a designate of UUNET, John
W. Sidgmore. The Company also granted UUNET registration rights identical to
those presently held by most of the Company's existing stockholders. For the
year ended December 31, 1995 and the six-month period ended June 30, 1996,
EarthLink paid UUNET approximately $52,000 and approximately $1.3 million for
network services.
 
    Linwood A. Lacy, Jr., a member of the Company's Board of Directors, also
serves as President and Chief Executive Officer of Micro Warehouse Incorporated
("Micro Warehouse"), one of the Company's affinity marketing partners. For the
nine-month period ended September 30, 1996, the Company paid Micro Warehouse
approximately $177,000 in bounties for new Company customers generated by Micro
Warehouse.
 
    The Company believes that the foregoing transactions were on terms no less
favorable to the Company than could be obtained from unaffiliated parties. It is
the Company's current policy that all transactions by the Company with officers,
directors, more than five percent stockholders and their affiliates will be
entered into only if such transactions are approved by a majority of
disinterested independent directors and are on terms such directors believe are
no less favorable to the Company than could be obtained from unaffiliated
parties.

                          DESCRIPTION OF CAPITAL STOCK
 
    The authorized capital stock of the Company consists of (i) 50 million
shares of Common Stock, $0.01 par value per share, and (ii) 10 million shares of
Preferred Stock, $0.01 par value per share, of which there is one authorized
series, Series A Convertible Preferred Stock, consisting of 2,727,273 authorized
shares. As of September 30, 1996, there were 12,045,465 shares of Common Stock
outstanding and 2,727,273 shares of Series A Convertible Preferred Stock. Each
share of Series A Convertible Preferred Stock will automatically convert into
one share of Common Stock upon consummation of this Offering. The following
summary is qualified in its entirety by reference to the Company's Certificate
of Incorporation, which is filed as an exhibit to the Registration Statement of
which this Prospectus is a part.
 
COMMON STOCK
 
    Under the Delaware General Corporation Law and the Company's Certificate of
Incorporation, holders of Common Stock are entitled to one vote per share on all
matters submitted to a vote of the stockholders, including the election of
directors. The Company's Certificate of Incorporation provides for cumulative
voting rights in the election of directors, meaning that in such elections (i)
each stockholder is entitled to cast such number of votes as is equal to the
product of the number of shares owned by such stockholder multiplied by the
number of directors standing for election and (ii) each stockholder may cast all
of such votes for a single director or may distribute them among any two or more
candidates for election as such stockholder chooses. Following the first meeting
of its stockholders subsequent to this Offering, and provided that there are 800
or more beneficial owners of the Common Stock, the Company anticipates that it
will seek stockholder approval to eliminate cumulative voting. The Common Stock
carries no preemptive rights and is not convertible, redeemable or assessable.
The holders of Common Stock are entitled to dividends in such amounts and at
such times as may be declared by the Board of Directors out of funds legally
available therefor. See "Dividend Policy." Upon the liquidation, dissolution or
winding up of the Company, the holders of Common Stock are entitled to receive
ratably the net assets of the Company available after payment or provision for
payment of all debts and other liabilities subject to prior rights of holders of
Preferred Stock then outstanding, if any. All shares of Common Stock outstanding
immediately following this Offering will be fully paid and non-assessable.
 
PREFERRED STOCK
 
    The Company's Certificate of Incorporation authorizes the issuance of 10
million shares of Preferred Stock, all of which will be available for future
issuance upon consummation of this Offering. Preferred Stock may be issued from
time to time in one or more series, and the Board of Directors, without further
approval of the stockholders, is authorized to fix the dividend rights and
terms, conversion rights, voting rights, redemption rights and terms,
liquidation preferences, sinking funds and any other rights, preferences,
privileges and restrictions applicable to each such series of Preferred Stock.
The issuance of Preferred Stock, while providing flexibility in connection with
possible acquisitions and other corporate purposes, could, among other things,
adversely affect the voting power of the holders of Common Stock and, under
certain circumstances, make it more difficult for a third party to gain control
of the Company, discourage bids for the Common Stock at a premium, or otherwise
adversely affect the market price of the Common Stock.
 
CERTAIN CHARTER AND BYLAW PROVISIONS
 
    Following the consummation of this Offering, the Company will be subject to
the "business combination" statute of the Delaware General Corporation Law. This
statute prohibits a publicly-held Delaware corporation from engaging in a
"business combination" with an "interested stockholder" for a period of three
years after the date of the transaction in which the person became an interested
stockholder, unless the business combination is approved in a prescribed manner,
such as the approval of a majority of certain members of the Board of Directors.
The term "business combination" includes mergers and stock and asset sales. An
"interested stockholder" is a person who, together with affiliates and
associates, owns (or within three years,
 
                                       45
<PAGE>
did own) 15% or more of the corporation's voting stock. The effect of this
statute could, among other things, make it more difficult for a third party to
gain control of the Company, discourage bids for the Common Stock at a premium
or otherwise adversely affect the market price of the Common Stock.
 
LIMITATION OF DIRECTORS' AND OFFICERS' LIABILITY; INDEMNIFICATION
 
    The Company has included in its Certificate of Incorporation provisions that
limit the personal liability of its officers and directors for monetary damages
for breach of their fiduciary duty of directors, except for liability that
cannot be eliminated under the Delaware General Corporation Law. The Certificate
of Incorporation provides that, to the fullest extent provided by the Delaware
General Corporation Law, directors of the Company will not be personally liable
for monetary damages for breach of their fiduciary duty as directors. The
Delaware General Corporation Law does not permit a provision in a corporation's
certificate of incorporation that would eliminate such liability (i) for any
breach of their duty of loyalty to the Company or its stockholders, (ii) for
acts or omissions not in good faith or that involve intentional misconduct or a
knowing violation of law, (iii) for any unlawful payment of a dividend or
unlawful stock repurchase or redemption, as provided in Section 174 of the
Delaware General Corporation Law, or (iv) for any transaction from which the
director derived an improper personal benefit.
 
    While these provisions provide directors with protection from awards for
monetary damages for breaches of their duty of care, they do not eliminate such
duty. Accordingly, these provisions will have no effect on the availability of
equitable remedies such as an injunction or rescission based on a director's
breach of his or her duty of care. The provisions described above apply to an
officer of a corporation only if he or she is a director of such corporation and
is acting in his or her capacity as director, and do not apply to the officers
of the corporation who are not directors.
 
    The Company's Bylaws provide that, to the fullest extent permitted by the
Delaware General Corporation Law, the Company may indemnify its directors,
officers and employees. The Bylaws further provide that the Company may
similarly indemnify its other employees and agents. In addition, the Company
anticipates that each director will enter into an indemnification agreement with
the Company pursuant to which the Company will indemnify such director to the
fullest extent permitted by the Delaware General Corporation Law. At present,
there is no pending litigation or proceeding involving a director or officer of
the Company in which indemnification is required or permitted, and the Company
is not aware of any threatened litigation or proceeding that may result in a
claim for such indemnification.
 
REGISTRATION RIGHTS
 
    The holders of substantially all of the shares of Common Stock and all of
the shares of Series A Convertible Preferred Stock outstanding prior to this
Offering (including the Company's founder and Chairman of the Board and its
President and Chief Executive Officer) as well as certain holders of warrants
and convertible debt are parties to registration rights agreements with the
Company. These agreements provide incidental or "piggyback" registration rights
that allow such holders, under certain circumstances, to include shares of
Common Stock in registration statements initiated by the Company or other
stockholders. These agreements also permit demand registrations on Form S-3
registration statements at such time when the Company is eligible to register
its capital stock on such form. These agreements do not permit holders of
registration rights to include their shares of Common Stock in this Offering.
See "Shares Eligible for Future Sale."
 
TRANSFER AGENT AND REGISTRAR
 
    The Company's Transfer Agent and Registrar is American Stock Transfer &
Trust Company.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Prior to this Offering, there has been no market for the Common Stock.
Future sales of substantial amounts of Common Stock in the public market could
adversely affect market prices prevailing from time to time. Sales of
substantial amounts of Common Stock in the public market after various
restrictions lapse could adversely affect the prevailing market price and the
ability of the Company to raise equity capital in the future.
 
    Upon the completion of this Offering,          shares of Common Stock will
be outstanding. Of these shares, the         shares of Common Stock sold in this
Offering will be freely tradable without restriction under the Securities Act,
except that shares purchased by "affiliates" of the Company, as that term is
defined in Rule 144 under the Securities Act, may generally be sold only in
compliance with the limitations of Rule 144.
 
    The shares of Common Stock held by existing stockholders prior to this
Offering were issued and sold by the Company in reliance on exemptions from the
registration requirements of the Securities Act and are deemed "restricted
shares" under Rule 144. These shares may be sold in the public market only if
registered, or pursuant to an exemption from registration such as those provided
by Rules 144 or 701 under the Securities Act. The holders of       shares of
Common Stock,       shares of Series A Convertible Preferred Stock and warrants,
options and convertible securities to purchase       shares of Common Stock
(including all of the Company's directors and officers) have entered into
lock-up agreements under which they have agreed not to offer, sell or otherwise
dispose of any shares of Common Stock, any options or warrants to acquire shares
of Common Stock or securities exchangeable for or convertible into shares of
Common Stock owned by them for a period of one year after the date of this
Prospectus, without the prior written consent of the Underwriter. The Company
has entered into a similar agreement, except that the Company may grant
additional options under its 1995 Stock Option Plan or issue shares of Common
Stock under outstanding options, warrants and convertible securities.
 
    Upon expiration of the lock-up agreements,         shares will become
eligible for immediate public resale subject to Rule 144. The remaining
shares held by existing stockholders will become eligible for public resale
following expiration of the lock-up agreements at various times over a period of
less than two years following the completion of this Offering, subject in some
cases to volume limitations. The holders of substantially all of the shares of
the shares of Common Stock and all of the shares of Series A Convertible
Preferred Stock outstanding prior to this Offering (including the Company's
founder and Chairman and its President and Chief Executive Officer) as well as
certain holders of warrants and convertible debt are parties to registration
rights agreements with the Company that provide incidental or "piggyback"
registration rights that allow such holders, under certain circumstances, to
include shares of Common Stock in registration statements initiated by the
Company or other stockholders. Such registration rights agreements also permit
demand registrations on Form S-3 registration statements at such time as the
Company is eligible to register securities on such form. The number of shares
sold in the public market could increase if such rights are exercised. See
"Description of Capital Stock -- Registration Rights."
 
    As of September 30, 1996, 4,674,371 shares were subject to outstanding
options and warrants. Of these shares,         are subject to the lock-up
agreements described above. Approximately 90 days after the date of this
Prospectus, the Company intends to file a Registration Statement on Form S-8
covering shares issuable under the Company's 1995 Stock Option Plan (including
shares subject to then outstanding options under such plans), thus permitting
the resale of such shares in the public market without restriction under the
Securities Act after expiration of the applicable lock-up agreements.
 
    Following the expiration of the 90-day period following the date of this
Prospectus, 2,891,083 shares of Common Stock subject to outstanding options will
become eligible for sale, to the extent they are vested, without restriction in
the public market pursuant to Rule 701; however, all of such shares will be
subject to lock-up agreements for an additional 275 days.
 
    In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated) who has beneficially owned shares for at least two
years (including the holding period of any prior owner, except an affiliate) is
entitled to sell within any three month period commencing 90 days after the date
of this Prospectus,
 
                                       47
<PAGE>
a number of shares that does not exceed the greater of (i) one percent of the
number of shares of Common Stock then outstanding or (ii) the average weekly
trading volume of the Common Stock during the four calendar weeks preceding the
required filing of a Form 144 with respect to such sale. Sales under Rule 144
are generally subject to certain manner of sale provisions and notice
requirements and to the availability of current public information about the
Company.
 
    The Securities and Exchange Commission (the "Commission") has recently
proposed reducing the initial Rule 144 holding period to one year. There can be
no assurance as to if or when such rule changes will be enacted. If enacted,
such modifications will have a material effect on the times when shares of the
Company's Common Stock become eligible for resale.

                                  UNDERWRITING
 
    Under the terms and subject to the conditions contained in an Underwriting
Agreement dated            , 1996 (the "Underwriting Agreement"), the
Underwriter has agreed to purchase from the Company       shares of Common Stock
at the initial public offering price less the underwriting discounts and
commissions set forth on the cover page of this Prospectus.
 
    The Underwriting Agreement provides that the obligations of the Underwriter
are subject to certain conditions precedent and that the Underwriter will be
obligated to purchase all of the shares of Common Stock offered hereby if any
are purchased.
 
    The Company has granted the Underwriter an option, expiring at the close of
business on the 30th day after the date of this Prospectus, to purchase up to
       additional shares of Common Stock at the initial public offering price
less the underwriting discounts and commissions as set forth on the cover page
of this Prospectus. Such option may be exercised only to cover over-allotments
in the sale of the shares of Common Stock.
 
    The Company has been advised by the Underwriter that the Underwriter
proposes to offer the Common Stock to the public initially at the offering price
set forth on the cover page of this Prospectus. The Underwriter may allot to
certain dealers a concession of $  per share, and the Underwriter and such
dealers may re-allow a concession of $  per share on sales to certain other
dealers. After the initial public offering, the public offering price and
concessions to dealers may be changed by the Underwriter.
 
    The Company, the holders of       shares of Common Stock,       shares of
Series A Convertible Preferred Stock and warrants, options and convertible
securities to purchase       shares of Common Stock (including all of the
Company's officers and directors) have entered into lock-up agreements under
which they have agreed, subject to limited exceptions, not to offer, issue, sell
or otherwise dispose of any shares of Common Stock, any options or warrants to
acquire shares of Common Stock or securities exchangeable for or convertible
into shares of Common Stock owned by them for a period of one year after the
date of this Prospectus, without the prior written consent of the Underwriter.
See "Shares Eligible for Future Sale."
 
    The Company has agreed to indemnify the Underwriter against certain
liabilities, including civil liabilities under the Securities Act, or to
contribute to payments which the Underwriter may be required to make with
respect thereto.
 
    Prior to this Offering, there has been no public market for the Common
Stock. The initial public offering price will be determined through negotiations
between the Company and the Underwriter and may not be indicative of the market
price of the Common Stock following this Offering. Among the factors to be
considered in such negotiations are an estimate of the business potential of the
Company, the present state of the Company's development, an assessment of the
Company's management, prevailing market conditions, the demand for similar
securities of comparable companies and other factors deemed relevant.
 
    As of October 31, 1996, the Underwriter and certain officers and employees
of the Underwriter held 113,635 shares of Series A Convertible Preferred Stock.
In addition, two minority shareholders and directors of the Underwriter's
corporate parent own an aggregate of 13,636 shares of Series A Convertible
Preferred Stock. Such stock was purchased in September 1996 for $5.50 per share.
 
                                 LEGAL MATTERS
 
    The validity of the issuance of the shares of Common Stock offered hereby
will be passed upon for the Company by Hunton & Williams, Atlanta, Georgia.
Certain legal matters in connection with the Offering will be passed upon for
the Underwriters by Morgan, Lewis & Bockius LLP, Philadelphia, Pennsylvania.

                         NOTES TO FINANCIAL STATEMENTS
 
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  ORGANIZATION
 
    EarthLink Network, Inc. ("EarthLink" or the "Company") was organized on May
26, 1994 and is an Internet service provider that was formed to help users
derive meaningful benefits from the extensive resources of the Internet.
 
    The Company has experienced operating losses since its inception as a result
of efforts to build its network infrastructure and internal staffing, develop
its systems, and expand into new markets. The Company expects to continue to
focus on increasing its customer base and to expend substantial resources on
sales, marketing and administration, building its network systems, developing
new service offerings and improving its management information systems.
Accordingly, the Company expects its cost of revenues, selling, general, and
administrative expenses and capital expenditures will continue to increase
significantly, all of which will have a negative impact on short-term operating
results. In addition, the Company may change its pricing policies to respond to
a changing competitive environment. There can be no assurance that growth in the
Company's revenues or customer base will continue or that the Company will be
able to achieve or sustain profitability or positive cash flow. The failure of
the Company to achieve or sustain profitability or positive cash flow may
require the Company to reduce the scope of its operations or its anticipated
expansion, which could adversely affect the Company's business and results of
operations.
 
  REVENUES
 
    Recurring revenues from monthly Internet service are recognized over the
period services are provided. Other revenues, consisting primarily of sign-up
fees, are recognized as revenue when earned.
 
  CASH AND CASH EQUIVALENTS
 
    All highly liquid investments with an original maturity of three months or
less at the date of acquisition are classified as cash equivalents.
 
  ACCOUNTS RECEIVABLE AND DEFERRED REVENUES
 
    Commencing in 1995, the Company began to bill for Internet service generally
one month in advance. Accordingly, these non-cancelable advanced billings are
included in both accounts receivable and deferred revenue.
 
  PROPERTY AND EQUIPMENT
 
    Property and equipment are depreciated using the straight-line method over
the estimated useful life of the assets, which is generally three years.
Leasehold improvements are amortized using the straight line method over the
shorter of their estimated lives or the term of the lease.
 
  EQUIPMENT UNDER CAPITAL LEASE
 
    The Company leases certain of its data communications and other equipment
under capital lease agreements. The assets and liabilities under capital lease
are recorded at the lesser of the present value of aggregate future minimum
lease payments, including estimated bargain purchase options, or the fair value
of the assets under lease. Assets under capital lease are amortized over the
lesser of their estimated useful lives of three years or the term of the lease.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  INTANGIBLES
 
    Intangible assets consist primarily of deferred financing costs, prepaid
lease guarantee costs, goodwill, rights to client lists and a covenant not to
compete. The costs assigned to intangible assets are being amortized on a
straight-line basis over the estimated useful lives of the assets, which range
from two to three years. The Company regularly reviews the recoverability of
intangible assets based on estimated undiscounted future cash flows from
operating activities compared with the carrying values of the intangibles.
 
  ACCOUNTING FOR STOCK-BASED COMPENSATION
 
    The Financial Accounting Standards Board issued Statement of Financial
Accounting Standards No. 123, "Accounting for Stock Based Compensation" (SFAS
123), effective for years beginning after December 15, 1995. For purposes of
recording expense associated with stock-based compensation, the Company intends
to continue to apply the provisions of APB Opinion No. 25 and related
interpretations. The effect of adoption of SFAS 123 in the year ending December
31, 1996 is not expected to be material.
 
  ADVERTISING AND CUSTOMER ACQUISITION COSTS
 
    Advertising and customer acquisition costs are included in sales and
marketing. Such costs are expensed as incurred.
 
  INCOME TAXES
 
    Income taxes are accounted for under Statement of Financial Accounting
Standards No. 109, "Accounting for Income Taxes." Under this method, deferred
tax assets and liabilities are determined based on differences between the
financial reporting basis and tax basis of assets and liabilities and are
measured using the enacted tax rates and laws that will be in effect when the
differences are expected to reverse.
 
  NET LOSS PER SHARE
 
    Net loss per share is computed using the weighted average number of common
shares outstanding. In addition, pursuant to Securities and Exchange Commission
Staff Accounting Bulletin No. 83, Common Stock and Common Stock equivalent
shares issued by the Company at prices below the public offering price during
the twelve-month period prior to the proposed offering date (using the treasury
stock method and an assumed initial public offering price of $8.00 per share)
including Common Stock pending issuance have been included in the calculation as
if they were outstanding for all periods regardless of whether they are
dilutive. Common Stock equivalent shares issued by the Company more than twelve
months prior to the proposed offering date have been excluded from the net loss
per share calculation because the impact is anti-dilutive.
 
  CONCENTRATIONS OF CREDIT RISK
 
    Financial instruments that potentially subject the Company to concentrations
of credit risk consists principally of cash investments and trade receivables.
The Company's cash investment policies limit investments to short-term, low-risk
instruments. Concentrations of credit risk with respect to trade receivables are
limited due to the large number of customers comprising the Company's customer
base.
 
  USE OF ESTIMATES IN PREPARATION OF FINANCIAL STATEMENTS
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and
 
                                      F-8

liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
 
  INTERIM FINANCIAL STATEMENTS
 
    The interim financial data is unaudited. However, in the opinion of the
Company, the interim financial data includes all adjustments, consisting only of
normal recurring adjustments, necessary for a fair statement of the results for
the interim periods.
 
2.  PURCHASE OF CERTAIN ASSETS FROM BECKEMEYER DEVELOPMENT TECHNOLOGIES
 
    In order to recruit the principal shareholder of Beckemeyer Development
Technologies ("BDT") to serve as the Company's Vice President of Engineering, on
November 7, 1995, the Company agreed to purchase all fixtures, equipment, and
the client list of BDT for cash of $64,000. In addition to the above, the
principal shareholder was issued warrants to purchase 20,661 shares of the
Company's Common Stock at $2.42 per share as consideration for an agreement not
to compete for a two-year period. The value assigned to the warrants was $5,000
based upon an appraisal obtained by the Company. The warrants expire October 10,
2005. This purchase price was allocated to the assets acquired with the
remainder reflected as an intangible asset. At the time of purchase, BDT was not
material to the results of operations, financial position or customer base of
EarthLink.

    Property and equipment consist of:

to option, and the option vesting period. The exercise price of all options
granted under the plan must be at least 85% of the fair market value (for

8.  INCOME TAXES
 
    The stockholders, upon incorporating the Company, elected to treat the
Company as an S Corporation under the Internal Revenue Code. On June 19, 1995,
this election was revoked as certain ineligible entities (i.e partnerships and
corporations) became stockholders. Losses of $1,261,000 incurred from inception
through June 19, 1995 have been reclassified from accumulated deficit to Common
Stock as a result of the change to C Corporation status. The Company is now
subject to income taxes on income earned after June 19, 1995. At December 31,
1995, the Company had net operating loss carryforwards for federal income tax
purposes totaling approximately $3,328,000, which begin to expire in 2010.
Operating loss carryforwards for state income tax purposes totaling
approximately $1,664,000 begin to expire in 2001. The Tax Reform Act of 1986
includes provisions which may limit the net operating loss carryforwards
available for use in any given year if certain events occur, including
significant changes in ownership. If the Company is successful in completing its
proposed initial public offering, utilization of the Company's net operating
loss carryforwards to offset future income may be limited.

  SIGNIFICANT AGREEMENTS
 
    Access to the Internet for customers outside of the Company's California
regional base is provided through points of presence ("POP") capacity leased
from UUNET Technologies, Inc. ("UUNET"). EarthLink is in effect a reseller of
UUNET's services, buying in bulk at a discount, and providing access to
EarthLink's customer base at EarthLink's normal rates. Payment to UUNET is
generally concurrent with EarthLink's receipt of funds from customers. UUNET
announced it would be acquired by MFS Communications, Inc. ("MFS"), a supplier
of local and long distance telephone service. There can be no assurance that
following the acquisition, MFS or UUNET will continue to provide the same
service and at affordable rates. Although leased POP capacity is available from
several alternative suppliers, there can be no assurance that the Company could
obtain substitute services from other providers at reasonable prices or in a
timely fashion.
 
    EarthLink has licensed Netscape Navigator software ("Netscape Navigator"),
the World Wide Web client software, from Netscape Communications Corporation.
This license permits the Company to distribute Netscape Navigator as part of its
EarthLink Network TotalAccess software package. Management believes that
contract renewal, under conditions acceptable to EarthLink, is probable.

    (b)  Financial Statement Schedules:
 
    All of the financial statement schedules for which provision is made in the
applicable accounting regulations of the Commission are either not required
under the related instructions or are inapplicable and have therefore been
omitted, except for the Financial Data Schedule referenced above as Exhibit 27
and filed herewith; provided, however, that Exhibit 27 shall not be deemed filed
for purposes of Section 11 of the Securities Act, Section 18 of the Exchange Act
and Section 323 of the Trust Indenture Act, or otherwise be subject to the
liabilities of such sections, nor shall it be deemed a part of this Registration
Statement.
 
ITEM 17.  UNDERTAKINGS
 
    The Company hereby undertakes to provide the Underwriter at the closing
specified in the underwriting agreement, certificates in such denominations and
registered in such names as required by the Underwriter to permit prompt
delivery to each Purchaser.
 
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended, may be permitted to directors, officers and controlling
persons to the Company, the Company has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Securities Act and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by the Company of expenses incurred or paid by a director, officer or
controlling person of the Company in the successful defense of any action, suit
or proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the
 
                                      II-6
<PAGE>
Company will, unless in the opinion of its counsel the matter has been settled
by controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.
 
    The undersigned registrant hereby undertakes that:
 
    (1)  For purposes of determining any liability under the Securities Act, the
information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in the form of a
prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this registration
statement as of the time it was declared effective.
 
    (2)  For the purpose of determining any liability under the Securities Act,
each post-effective amendment that contains a form of prospectus shall be deemed
to be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.

                               EARTHLINK NETWORK, INC.

                              CERTIFICATE OF DESIGNATION,
                              PREFERENCES AND RIGHTS OF
                         SERIES A CONVERTIBLE PREFERRED STOCK

                      -----------------------------------------

                           PURSUANT TO SECTION 151 OF THE 
                   GENERAL CORPORATION LAW OF THE STATE OF DELAWARE

                      ------------------------------------------

         EarthLink Network, Inc. (the "Corporation"), certifies that pursuant 
to the authority contained in Article IV of its Amended and Restated 
Certificate of Incorporation, and in accordance with the provisions of Section 
151 of the General Corporation Law of the State of Delaware, its Board of 
Directors has adopted the following resolution creating a series of the 
Preferred Stock, $.01 par value, designated as Series A Preferred Stock:

         RESOLVED, that a series of the class of Preferred Stock, $.01 par
value, of the Corporation be hereby created, and that the designation and amount
thereof and the voting powers, preferences, and relative, participating,
optional and other special rights of the shares of such series, and the
qualifications, limitations or restrictions thereof are as follows:

         1.   DESIGNATION AND AMOUNT.  The shares of such series shall be
designated "Series A Convertible Preferred Stock" (herein referred to as "Series
A Preferred Stock"), having a stated value per share equal to $.01, and the
number of shares constituting such series shall be 2,727,273.

         2.   DIVIDEND PROVISIONS: DEFINITIONS.

         (a)  CASH DIVIDENDS.  In case the Corporation at any time or from time
to time shall declare, order, pay or make a cash dividend on the Nonpreferred
Stock (as defined below) of the Corporation, the Board of Directors shall, at
the same time or times declare, order, pay and make a cash dividend on each
share of Series A Preferred Stock in an amount equal to the product of the
amount of such dividend declared, ordered, paid or made on each share of
Nonpreferred Stock, multiplied by the number of shares of Common Stock into
which the share of Series A Preferred Stock is convertible on the record date
for such action.  So long as any shares of Series A Preferred Stock are
outstanding, the Corporation shall not declare, order, pay or make a cash
dividend on any shares of Nonpreferred Stock unless it likewise declares,
orders, pays or makes such a cash dividend on all shares of Nonpreferred Stock.

         (b)  OTHER DISTRIBUTIONS.  In case the Corporation at any time or from
time to time shall declare, order, pay or make a dividend or other distribution
(including, without limitation, any distribution of other or additional stock or
other securities or property or rights or


<PAGE>


warrants to subscribe for securities of the Corporation or any of its 
subsidiaries by way of dividend or spin-off, reclassification, 
recapitalization or similar corporate rearrangement) on its Nonpreferred 
Stock, other than a dividend payable in cash or shares of the Corporation's 
Nonpreferred Stock, then the Board of Directors shall, at the same time or 
times, declare, order pay and make a dividend or other distribution on each 
share of Series A Preferred Stock which is equivalent to such dividend or 
other distribution declared, ordered, paid or made on each share of 
Nonpreferred Stock, multiplied by the number of shares of Common Stock into 
which a share of Series A Preferred Stock is convertible on the record date 
for such action.  So long as any shares of Series A Preferred Stock are 
outstanding, the Corporation shall not declare, order, pay or make any such 
dividend or other distribution unless it likewise declares, orders, pays or 
makes such dividend or other distribution  unless it likewise declares, 
orders, pays or makes such dividend or other distribution on all shares of 
Nonpreferred Stock.

         (c)  LIMITATION ON DISTRIBUTIONS.  No deposit, payment, dividend or 
distribution of any kind shall be made with respect to the Nonpreferred Stock 
unless all accumulations of dividends payable on the Series A Preferred Stock 
shall have been paid.  So long as any Series A Preferred Stock shall remain 
outstanding, no dividend or other distribution (except in Junior Shares) 
shall be paid or made on the Nonpreferred Stock of the Corporation (except in 
accordance with subsections (a) and (b) of this Section 2) or on other Junior 
Shares of the Corporation and no share of Nonpreferred Stock or other Junior 
Shares shall be purchased or otherwise acquired by the Corporation or any 
subsidiary of the Corporation.

         Subject to the above limitations, dividends may be paid on the
Nonpreferred Stock out of any funds legally available for such purpose when and
as declared by the Board of Directors, provided that dividends are also paid on
the Series A Preferred Stock in accordance with subsections (a) and (b) of this
Section 2.

         (d)  CERTAIN DEFINITIONS.

         As used in this Section 2 and elsewhere in this Certificate of
Designation, Preferences and Rights of Series A Preferred Stock, unless the
context otherwise requires:

              (i)       The term "Common Stock" shall mean the Corporation's
authorized Common Stock, $.01 par value, as constituted on September 10, 1996,
and any stock into which such Common Stock may thereafter be changed, and shall
also include stock of the Corporation of any other class, which is not preferred
as to dividends or assets over any other class of stock of the Corporation,
issued to the holders of shares of Common Stock upon any reclassification
thereof.

              (ii)      The term "Nonpreferred Stock" shall mean the Common
Stock and shall also include stock of the Corporation of any other class that
has no preference as to dividends or distributions of assets over any other
class of stock of the Corporation and that is not subject to redemption.

              (iii)     The term "Junior Shares" shall mean any class or series
of stock junior to the Series A Preferred Stock as to dividends and distribution
of assets.

<PAGE>
                   (iv)  The term "Liquidation Event" shall mean the
liquidation, dissolution or winding up of the Corporation, either voluntary or
involuntary and such other events that may be deemed to be liquidation events
pursuant to subsection 3(c) below.

                   (v)  The term "Control Transaction" shall have the meaning
set forth in subsection 3(c) below.

              3.   LIQUIDATION PREFERENCE.

              (a)  In the event of any Liquidation Event, the holders of Series
A Preferred Stock shall be entitled to receive, prior and in preference to any
distribution of any of the assets of this Corporation to the holders of
Nonpreferred Stock and other Junior Shares by reason of their ownership thereof,
an amount per share equal to the sum of (i) $5.50 for each outstanding share of
Series A Preferred Stock and (ii) all accumulations of unpaid dividends on each
share of Series A Preferred Stock. If upon the occurrence of such Liquidation
Event, the assets and funds thus distributed among the holders of the Series A
Preferred Stock shall be insufficient to permit the payment to such holders of
the full aforesaid preferential amounts, then the entire assets and funds of the
Corporation legally available for distribution shall be distributed ratably
among the holders of the Series A Preferred Stock in proportion to the amount of
such Series A Preferred Stock owned by each such holder.

              (b)  After the distribution described in subsection (a) has been
paid, the remaining assets of the Corporation available for distribution to
shareholders shall be distributed among the holders of Junior Shares in
accordance with their respective rights thereto.

              (c)  A consolidation or merger of the Corporation with or into
any other corporation or corporations (other than a merger that is not part of a
Control Transaction and that, pursuant to the provisions of Section 251(f) of
the General Corporation Law of the State of Delaware, does not require approval
by stockholders of the Corporation), or a sale, conveyance or disposition of all
or substantially all of the assets of the Corporation or the effectuation by the
Corporation or its stockholders of a transaction or series of related
transactions in which more than 50% of the voting power of the Corporation is
disposed of (a "Control Transaction"), shall be deemed to be a Liquidation
Event, if the holders of at least 60% of the outstanding Series A Preferred
Stock elect to have such transaction treated as a Liquidation Event.

              4.   CONVERSION.  The holders of the Series A Preferred Stock
shall have conversion rights as follows (the "Conversion Rights"):

              (a)  OPTIONAL CONVERSION RIGHTS AND AUTOMATIC CONVERSION.

                   (i)  Each share of Series A Preferred Stock shall be
convertible, at the option of the holder thereof, at any time after March 10,
1997, at the office of the Corporation or any transfer agent for the Series A
Preferred Stock, into such number of fully paid and nonassessable shares of
Common Stock as is determined by dividing 5.50 by the Conversion


                                          3

<PAGE>

Factor at the time in effect for such share. The initial Conversion Factor per
share for shares of Series A Preferred Stock shall be 5.50. The Conversion
Factor for the Series A Preferred Stock shall be subject to adjustment as set
forth in this Section 4.

                   (ii)  Each share of Series A Preferred Stock shall
automatically be converted into shares of Common Stock as is determined by
dividing 5.50 by the Conversion Factor at the time in effect for such Series A
Preferred Stock: (a) immediately upon the consummation of the Corporation's sale
of its Common Stock in a bona fide, firm commitment underwriting pursuant to a
registration statement on Form S-1 under the Securities Act of 1933, as amended
(or any equivalent successor form), the public offering price of which was not
less than $8.00 per share (adjusted to reflect changes after September 9, 1996
in the number of shares of Common Stock outstanding by reason of stock
dividends, stock splits or recapitalizations or the like) and the net proceeds
to the Corporation of which were not less than $20 million (a "Qualifying Public
Offering").

                   (iii)  Upon conversion of any Series A Preferred Stock,
payment shall be made by the Corporation to each holder of the Series A
Preferred Stock so converted on account of dividends accrued but unpaid on the
Series A Preferred Stock.

         (b)  MECHANICS OF OPTIONAL CONVERSION.  If the holder of shares of
Series A Preferred Stock desires to exercise such right of conversion, he shall
give written notice to the Corporation (the "Conversion Notice") of his election
to convert a stated number of shares of Series A Preferred Stock (the
"Conversion Shares") into shares of Common Stock, and surrender to the
Corporation his certificate or certificates representing such Conversion Shares.
The Conversion Notice shall also contain a statement of the name or names (with
addresses) in which the certificate or certificates for Common Stock shall be
issued. Notwithstanding the foregoing, the Corporation shall not be required to
issue any certificates to any person other than the holder thereof unless the
Corporation has obtained reasonable assurance that such transaction is exempt
from the registration requirements of, or is covered by an effective
registration statement under, the Securities Act of 1933, as amended (the
"Act"), and all applicable state securities laws, including, if necessary in the
reasonable judgment of the Corporation or its legal counsel, receipt of an
opinion to such effect from counsel reasonably satisfactory to the Corporation.
In no event would such opinion be required if the shares of Common Stock could,
upon conversion, be resold pursuant to rule 144 under the Act. Promptly after
the receipt of the Conversion Notice and the surrender of the certificate or
certificates representing the Conversion Shares, the Corporation shall issue and
deliver, or cause to be delivered, to the holder of the Conversion Shares or his
nominee or nominees, a certificate or certificates for the number of shares of
Common Stock issuable upon the conversion of such Conversion Shares. Such
conversion shall be deemed to have been effected as of the close of business on
the date the Corporation received the Conversion Notice and the certificate or
certificates representing the Conversion Shares, and the person or persons
entitled to receive the shares of Common Stock issuable upon conversion shall be
treated for all purposes as the holder or holders of record of such shares of
Common Stock as of the close of business on such date.


                                          4
<PAGE>

         (c)  MECHANICS OF AUTOMATIC CONVERSION.

              (i)    The Corporation shall give all holders of record of shares
of Series A Preferred Stock prior written notice of the date upon which the
registration statement relating to the Qualifying Public Offering will be
ordered effective by the Securities and Exchange Commission or is anticipated to
be ordered effective.  Such notice shall be given as promptly as practicable,
but in no event later than the date upon which the Company submits a request to
the Securities and Exchange Commission to accelerate the effectiveness of such
registration statement.  Such notice shall also specify the place designated for
exchanging shares of Series A Preferred Stock for shares of Common Stock, and
shall be sent by first class mail, postage prepaid, to each holder of record of
shares of Series A Preferred Stock at such holder's address as shown in the
records of the Corporation.  In the event that the Corporation gives notice of
an anticipated effective date of the Qualifying Public Offering and the actual
effective date is a different date, the conversion of the Series A Preferred
Stock shall nevertheless be effected in accordance with the provisions of this
Section 4.

              (ii)   From and after the date of conversion, all rights of the
holders of any shares of Series A Preferred Stock, as such, except for the right
to convert their shares of Series A Preferred Stock into shares of Common Stock
as provided in this Section 4, shall cease and terminate, regardless of whether
the holders of such shares of Series A Preferred Stock have tendered their
certificates therefor in accordance with this Section 4.

         (d)  CONVERSION FACTOR ADJUSTMENTS OF PREFERRED STOCK.

              (i)    In the event the Corporation should at any time or from 
time to time after September 10, 1996 (the "Purchase Date") fix a record date 
for the effectuation of a split or subdivision of the outstanding shares of 
Nonpreferred Stock or the determination of holders of Nonpreferred Stock 
entitled to receive a dividend or other distribution payable in additional 
shares of Nonpreferred Stock, then, as of such record date (or, if no record 
date is fixed, as of the close of business on the date on which the Board of 
Directors adopts the resolution relating to such dividend, distribution, 
split or subdivision), the Conversion Factor in effect immediately prior to 
such date shall be multiplied by a fraction, the numerator of which shall be 
the number of shares of Commmon Stock outstanding immediately prior thereto 
and the denominator of which shall be the number of shares of Common Stock 
outstanding immediately thereafter.  So long as any shares of Series A 
Preferred Stock are outstanding, the Corporation shall not fix a record date 
for, or effect, such a dividend, distribution, split or subdivision on any 
shares of Nonpreferred Stock unless it likewise fixes a record date for, or 
effects such a dividend, distribution, split or subdivision on all shares of 
Nonpreferred Stock.

              (ii)   If the number of shares of Nonpreferred Stock outstanding
at any time after the Purchase Date is decreased by a combination of the
outstanding shares of Nonpreferred Stock, then following such combination, the
Conversion Factor in effect immediately prior thereto shall be multiplied by a
fraction, the numerator of which shall be the number of shares of Common Stock
outstanding immediately prior thereto and the denominator of which shall be the
number of shares of Common Stock outstanding immediately thereafter.


                                          5

<PAGE>

So long as any shares of Series A Preferred Stock are outstanding, the
Corporation shall not combine any shares of Nonpreferred Stock unless it
likewise combines all shares of Nonpreferred Stock.

         (e)  RECAPITALIZATIONS, ETC.   If any capital reorganization or 
reclassification of the Common Stock of the Corporation (other than as set 
forth in subsection 2(b)), or consolidation or merger of the Corporation with 
or into another corporation, or the sale or conveyance of all or 
substantially all of its assets to another corporation, shall be effected, 
then, as a condition of such reorganization, reclassification, consolidation, 
merger or sale, lawful and adequate provision shall be made (unless such 
transaction is deemed to be a Liquidation Event pursuant to subsection 3(c)) 
whereby the holders of the Series A Preferred Stock shall thereafter have the 
right to receive, in lieu of the shares of Common Stock of the Corporation 
immediately theretofore receivable with respect to such shares of Series A 
Preferred Stock, such shares of stock, securities or assets as would have 
been issued or payable with respect to or in exchange for the shares of 
Common Stock which such holders would have held had the shares of Series A 
Preferred Stock been converted immediately prior to such reorganization, 
reclassification, consolidation, merger or sale.  In any such case, 
appropriate provisions shall be made with respect to the rights and interests 
of the holders of the Series A Preferred Stock to the end that such 
conversion rights (including, without limitation, provisions for adjustment 
of the Conversion Factor) shall thereafter be applicable, as nearly as may be 
practicable in relation to any shares of stock, securities or assets 
thereafter deliverable upon the exercise thereof.  The Corporation shall not 
consummate any such reorganization, reclassification, consolidation, merger 
or sale unless it provides the holders of the Series A Preferred Stock at 
least 20 days advance notice thereof.

         (f)  NO IMPAIRMENT.   The Corporation will not, by amendment of its
Certificate of Incorporation or through any reorganization, reclassification,
recapitalization, transfer of assets, consolidation, merger, dissolution, issue
or sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by the Corporation, but will at all times in good faith assist in the
carrying out of all the provisions of this Section 4 and in the taking of all
such action as may be necessary or appropriate in order to protect the
conversion rights of the holders of the Series A Preferred Stock against
impairment.  Without limiting the foregoing, the Company will not effect any
transaction described in Section 4(e), the result of which is to adversely
affect any of the rights of holders of Common Stock relative to the rights of
holders of any other Nonpreferred Stock.

         (g)  STOCK TRANSFER TAXES.   The issuance of stock certificates upon 
the conversion of the Series A Preferred Stock shall be made without charge 
to the converting holder for any tax in respect of such issuance.  The 
Corporation shall not, however, be required to pay any tax which may be 
payable in respect of any transfer involved in the issuance and delivery of 
shares in any name other than that of the holder of such shares of Series A 
Preferred Stock converted, and the Corporation shall not be required to issue 
or deliver any such stock certificate unless and until the person or persons 
requesting the issuance thereof shall have paid to the Corporation the amount 
of such tax, if any.

                                          6
<PAGE>


         (h)  NO FRACTIONAL SHARES: CERTIFICATE AS TO ADJUSTMENTS.


              (i)       No fractional shares shall be issued upon conversion of
the Series A Preferred Stock, and the number of shares of Common Stock to be
issued shall be rounded to the nearest whole share.

              (ii)      Upon the occurrence of each adjustment or readjustment
of the Conversion Factor of Series A Preferred Stock pursuant to this Section 4,
the Corporation, at its expense, shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and prepare and furnish to each
holder of Series A Preferred Stock a certificate setting forth such adjustment
or readjustment and showing in detail the facts upon which such adjustment or
readjustment is based.  The Corporation shall, upon the written request at any
time of any holder of Series A Preferred Stock, furnish or cause to be furnished
to such holder a like certificate setting forth (A) such adjustment and
readjustment, (B) the Conversion Factor at the time in effect, and (C) the
number of shares of Common Stock and the amount, if any, of other property which
at the time would be received upon the conversion of a share of Series A
Preferred Stock.

         (i)  NOTICES OF RECORD DATE.  In the event of any taking by the
Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, any right to
subscribe for, purchase or otherwise acquire any shares of stock or any class of
any other securities or property, or to receive any other right, the Corporation
shall mail to each holder of Series A Preferred Stock, at least 20 days prior to
the date specified therein, a notice specifying the date on which any such
record is to be taken for the purpose of such dividend, distribution or right,
and the amount and character of such dividend, distribution or right.

         (j)       RESERVATION OF STOCK ISSUABLE UPON CONVERSION.  The 
Corporation shall at all times reserve and keep available out of its 
authorized but unissued shares of Common Stock solely for the purpose of 
effecting the conversion of the shares of the Series A Preferred Stock, free 
from any preemptive right or other obligation, such number of its shares of 
Common Stock as shall from time to time be sufficient to effect the 
conversion of all outstanding shares of the Series A Preferred Stock; and if 
at any time the number of authorized but unissued shares of Common Stock 
shall not be sufficient to effect the conversion of all then outstanding 
shares of the Series A Preferred Stock, in addition to such other remedies as 
shall be available to the holder of such Series A Preferred Stock, the 
Corporation will take such corporate action as may be necessary to increase 
its authorized but unissued shares of Common Stock to such number of shares 
as shall be sufficient for such purposes.  The Corporation shall prepare and 
shall use its best efforts to obtain and keep in force such governmental or 
regulatory permits or other authorizations as may be required by law, and 
shall comply with all requirements as to registration, qualification or 
listing of the Common Stock, in order to enable the Corporation lawfully to 
issue and deliver to each holder of record of Series A Preferred Stock such 
number of shares of its Common Stock as shall from time to time be sufficient 
to effect the conversion of all Series A Preferred Stock then outstanding and 
convertible into shares of Common Stock.

                                          7

<PAGE>

         (k)       NOTICES.  Any notice required by the provisions of this
Section 4 to be given to the holders of shares of Series A Preferred Stock shall
be deemed given if deposited in the United States mail, postage prepaid, or by a
recognized commercial delivery service (e.g., United Parcel Service or Federal
Express), delivery prepaid and addressed to each holder of record at his address
appearing on the books of this Corporation.

         5.   VOTING RIGHTS

         (a)  ELECTION OF DIRECTORS

              (i)       The holders of the Series A Preferred Stock shall have
the exclusive right to elect one director.  The holders of the Common Stock and
the Series A Preferred Stock shall have the right to elect all other directors.

              (ii)      The director who shall have been elected solely by 
the holders of Series A Preferred Stock may be removed during his term of 
office, either for or without cause, by and only by, the affirmative vote of 
the holders of a majority of the shares of the Series A Preferred Stock who 
elected such director, given at a special meeting of such shareholders duly 
called for that purpose, and any vacancy thereby created may be filled by the 
holders of the Series A Preferred Stock represented at that meeting.

              (iii)     If the director who shall have been elected solely by 
the holders of Series A Preferred Stock shall cease to serve for any reason 
other than removal as set forth in Subsection (a)(ii) of this Section 5 
(including, without limitation, death, incapacity or resignation), any 
vacancy thereby created shall be filled exclusively by the holders of the 
Series A Stock.

         (b)  VOTING RIGHTS GENERALLY.  Subject to subsection (a) of this 
Section 5 and to Section 6, and except as otherwise required by law, the 
holder of each share of Series A Preferred Stock shall have the right to one 
vote for each share of Common Stock into which such Series A Preferred Stock 
could then be converted (with any fractional share determined on an aggregate 
conversion basis being rounded to the nearest whole share), and with respect 
to such vote, such holder shall have voting rights and powers equal to the 
voting rights and powers of the holders of Common Stock, and shall be 
entitled, notwithstanding any provision hereof, to notice of any 
shareholders' meeting in accordance with the by-laws of the Corporation, and 
shall be entitled to vote, together with holders of Common Stock, with 
respect to any question upon which holders of Common Stock have the right to 
vote.

         6.   PROTECTIVE PROVISIONS.  So long as shares of Series A
Preferred Stock are outstanding, this Corporation shall not, without first
obtaining the approval (by vote or written consent) of the holders of a majority
of the then outstanding shares of Series A Preferred Stock (voting in accordance
with Section 5):

         (a)  alter or change the rights, preferences or privileges of the
shares of Series A Preferred Stock so as to affect adversely the shares;

                                          8

<PAGE>

         (b)  increase the number of authorized shares of Series A Preferred 
Stock, or create any new series of stock or any other securities convertible 
into equity securities of the Corporation having a preference over, or being on
a parity with, the Series A Preferred Stock with respect to voting, dividends,
distribution of assets or conversion rights;

         (c)  Amend the Certificate of Incorporation or By-Laws of the 
Corporation or take any action or enter into any other agreements which prohibit
or conflict with the Corporation's obligations hereunder with respect to the 
holders of Series A Preferred Stock.

         7.   STATUS OF CONVERTED STOCK. In the event any shares of Series A
Preferred Stock shall be converted pursuant to Section 4 hereof, the shares so
converted shall be canceled and thereupon restored to the status of authorized
but unissued Preferred Stock undesignated as to class or series.

                      INTERNET SERVICES PROVIDER AGREEMENT

This Agreement is made in the city of _____, _____, this __ day of _____, 
199_, between __________________, whose address is ______________, _____, 
____________ (the "Company"), and ________________________________ whose 
address is _____________________________________________ ("Reseller").

The parties agree as follows:

1.  SERVICE  The Company will sell, and Reseller will purchase, 
telecommunications services for the interconnection of Reseller's end users 
with the Internet.  Reseller is responsible for all end-user customer 
support, billing, and collections.  The Company's relationship under this 
Agreement is solely with Reseller and not with any of Reseller's end users.  
The Company agrees that its telecommunications services provided to Reseller 
will be of a quality usual and customary in the Industry for similarly 
situated companies.  Although it is understood that the Company cannot 
guarantee continuous service, the Company agrees to provide prompt reparation 
of any disruption in services to the extent reasonably possible consistent 
with its obligations to other customers.

2.  PRICING  The Prices for services provided by the Company to Reseller are 
set forth on the attached Schedule A.

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

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

5.  TERM  The term of this Agreement is _____ from the date first set forth 
above, which term shall be automatically renewed for additional _____ terms, 
provided that neither party has delivered to the other party a written notice 
of intent not to renew for the forthcoming term.  Such notice of intent shall 
be given not less than _____ days in advance of the end of the current term.

6.  TERMINATION  Either party may terminate this Agreement for cause without 
penalty in the event that the other party hereto breaches any material term 
of this Agreement.  Prior to such termination, the party intending to 
terminate shall first give the other party written notice of its intent to 
terminate which shall clearly describe problem(s) constituting cause.  The 
other party will have _____ days from the date of receipt of such notice to 
correct the problem.  If the problem is not corrected within such period, the 
party intending to terminate may terminate this Agreement.  However, if 
Reseller shall violate the acceptable use policy in Section 2 of Schedule B, 
or permit such violation, and does not immediately act to remedy such 
violation when it becomes aware of it, the Company may terminate this 
Agreement without penalty with ten (10) days' written notice.  If any amounts 
due and owing by Reseller remain unpaid _____ days after date of invoice, 
then the Company may terminate this Agreement immediately upon written notice 
without penalty.  Either party may terminate this agreement for convenience 
_____ days after giving the other party written notice.  In the event of any 
such termination by Reseller, Reseller will pay the Company ________, in 
addition to paying all amounts currently due and owing.

7.  TESTING  The full effectiveness of this contract will be contingent upon 
the completion of technical testing to the mutual and reasonable satisfaction 
of both parties during the period of _____ days following execution of this 
Agreement.  If either party shall reasonably declare the testing results to 
be unsatisfactory at the conclusion of the _____ day period, then the parties 
shall have another _____ days to correct the problem.  If such correction is 
not completed to the mutual and reasonable satisfaction of the parties then 
this Agreement will terminate with no further liability to either party.  If 
no such declaration is made, acceptance of technical testing shall be 
presumed, and the contract shall remain in effect.

necessary for all parties to execute the same counterpart hereof.

18.  WAIVER  No failure on the part of either party to exercise, and no delay

     This Internet-Sign Up Referral and Microsoft Internet Explorer License 
and Distribution Agreement ("Agreement") is made and entered into this 16th 
day of August, 1996 ("Effective Date"), by and between MICROSOFT CORPORATION, 
a Washington corporation, One Microsoft Way, Redmond, WA 98052-6399 ("MS"),

owned subsidiaries and affiliates (collectively, "COMPANY").

                               INTRODUCTION

     This Agreement includes two distinct business arrangements.

     Under the first arrangements, MS plans to develop and distribute an 
"Internet Connection Wizard" as a means of promoting internet access services 
for various Internet access service providers, including COMPANY, and of 
acquiring subscribers for such access services.  COMPANY will pay MS a 
referral fee for each subscriber acquired by means of the Internet Connection 
Wizard.

     Under the second arrangement, COMPANY may distribute, on a royalty-free 
basis, a customized version of Microsoft Internet Explorer to subscribers 
or potential subscribers of its Internet access services.

     In consideration of the mutual promises and covenants contained herein,

    1.7  "Internet Connection Wizard" shall mean an electronic referral 
mechanism to be developed by MS to promote the ISP services for various ISP

             MICROSOFT-REGISTERED TRADEMARK- INTERNET EXPLORER
                       ONLINE LOGO USAGE GUIDELINES

                    This site is best experienced with
                                  [LOGO]
                           Click here to start.

1. USAGE
     Use the Internet Explorer online logo (the "logo") only to promote 
     Microsoft Internet Explorer and indicate that your Internet Site includes
     or is compatible with the Microsoft Internet Explorer.

     The Logo may only be used on your Internet Site which must meet the 
     applicable Logo Qualification Criteria and may not be used in any other 
     fashion.

     RECOMMENDED TEXT. Based upon extensive research, we suggest that the 
     Internet Explorer Logo be accompanied by the following text: "This site 
     is best experienced with ... Click here to start." as indicated in the 
     below images. This information clarifies how the logo should be used, 
     especially for new Internet visitors who are unfamiliar with the 
     different means of navigating the Internet.

                       This site is best experienced with
                                    [LOGO]

     PRODUCT NAME. It should appear as "Microsoft-Registered Trademark- 
     Internet Explorer" at the first and most prominent use in all materials 
     and can thereafter be referred to as "Internet Explorer."

2. INTENT
     You are not permitted to use the logo to disparage Microsoft, its 
     products or services, or for promotional goods or for products which, in 
     MS' reasonable judgement, may diminish or otherwise damage Microsoft's 
     goodwill in the Logo, including but not limited to uses which could be 
     deemed to be obscene, pornographic, excessively violent, or otherwise in 
     poor taste or unlawful, or which purpose is to encourage unlawful 
     activities. Similarly, you cannot imitate Microsoft's product packaging 
     or the Logo in any of your materials, including advertising, product 
     packaging, and promotional materials. The Logo must not be used in a 
     manner that implies Microsoft's sponsorship or endorsement of the 
     product, service, or content presented on your Internet Site.

3. LOGO LINK
     Used in an Internet Site, the Logo must be an active link to this 
     URL address:
                        http://www.microsoft.com/ie/ie.htm
                        ----------------------------------

<PAGE>

4. PRESENTATION
     PROMINENCE. Do not use the Logo or the names "Microsoft," "Microsoft 
     Internet Explorer," or "Internet Explorer" more prominently than your 
     company, product, or Internet Site name.

     ARTWORK. Use only Microsoft authorized electronic artwork of the Logo. 
     The Logo must stand by itself and must include a minimum amount of empty 
     space surrounding the Logo (30 pixels) so as to separate it from any 
     other object, such as type, photography, borders, edges, and so on. The 
     Logo may not be used as a feature or design element of any other Logo.

     SIZE. The Logo cannot be reduced in size beyond what is electronically 
     provided by Microsoft and must be placed in a prominent location on the 
     Internet Site where it is used. Do not remove any trademark symbols or 
     alter the Logo in any way. Redraws, distortions, or animation of the 
     Logo are not permitted beyond what is provided to authorized/registered 
     Microsoft Online logo Internet Sites.

     FOOTNOTE. Include the following footnote on Internet Sites that include 
     the Logo: "Microsoft is a registered trademark in the United States and 
     other countries and the Microsoft Internet Explorer Logo is a trademark  
     of Microsoft Corporation."

ALTERATIONS TO THESE GUIDELINES
Microsoft reserves the right to change the Logo and these Usage Guidelines at 
any time and solely at its discretion. If possible, Microsoft will provide 
advanced notice of these changes. Any use of the Logo that is not consistent 
with these guidelines is strictly prohibited.

CANCELLATION OF AUTHORIZATION TO HOST LOGO
Microsoft reserves the right to review use of the Internet Explorer Logo. 
Disregard for these Usage Guidelines may result in a revocation of the right 
to use the logo, and with it all benefits enjoyed through participation in 
the logo program.

Third parties improperly using the Logo must correct any deficiencies in 
their use of the Logo and/or in the quality of the product used in 
conjunction with the Logo upon reasonable notice from Microsoft. Refusal to 
correct such deficiencies may result in revocation of the right to use the 
Logo.

"[email protected]"

                                 [LOGO]

Microsoft has established the following set of guidelines to assist you in 
proper use of the Microsoft Internet Explorer standard logo (the "Logo").
The power of the Logo lies in its consistent and appropriate use. Any usage 
outside these guidelines dilutes the effectiveness of the Logo and makes it 
more difficult to defend our rights to the trademark.
Microsoft reserves the right to change the Logo and/or these Guidelines at 
any time at its discretion. Third parties shall comply with the Guidelines as 
amended from time to time.

ACCOMPANYING WORDS

The graphic may not be used without the words "Includes," 
"Microsoft-Registered Trademark-," and "Internet Explorer" attached, except 
as otherwise provided below. No additional or substitute words may be used. 
The words may not be abbreviated, translated, or transliterated, as in 
non-English documentation. Microsoft will, however, provide the Logo in 
versions where the word "Includes" may be translated for the local market, as 
available. You may not substitute your own translation of the Logo.

                                       25

<PAGE>

BLACK-AND-WHITE APPLICATIONS

The black-and-white Logo consists of a black graphic element and black type. 
Please use the file provided.

ACCESSING THE FILES

The print files are provided in Encapsulated PostScript-Registered Trademark- 
(EPS) and Windows-Registered Trademark- metafile (WMF) format. Use the EPS 
files for materials printed to a PostScript-compatible printer. Use the 
Windows metafile to print to a non-PostScript printer. These files should not 
be opened and edited, only placed (for example, select "import...picture") 
into software programs such as common page-layout or presentation programs, 
word-processing software, and so forth.
Due to translation problems between the Mac and PC, Mac-TM- EPS images may 
lose their preview. When you place them into your page-layout document, you 
will see a box or a big 'X' instead of the preview. The image will still 
print correctly and the bounding box accurately shows the size of the image. 
EPS images are sizable, but please scale proportionately.
PC EPS images only have black-and-white previews. If you chose to use a color 
PC EPS, it will still preview in black-and-white. When you print it, the 
color will print correctly.
EPS format is device-dependent so the resolution of the device you are 
printing to is the resolution you will achieve.
The art files include Adobe Illustrator (ART) and Macromedia Freehand (FH5) 
format. These are provided for use where the print files supplied will not 
work. They are not to be altered.

QUALITY CONTROL

Microsoft reserves the right to review your use of the Logo and to conduct 
spot checks on all products, product packaging, marketing materials, and 
documentation and may periodically send out requests for samples. Microsoft 
may also conduct spot checks in retail outlets and other product sources to 
monitor your compliance with these Logo Usage Guidelines. Refusal to submit 
samples, noncompliance with these Guidelines, or failure to correct any 
deficiencies in your use of the Logo and/or in the quality of the product 
used in conjunction with the Logo upon reasonable notice from Microsoft could 
result in revocation of your license to use the Logo.

        computers at remote locations which are operated by others and to 
        provide access to Internet.

1.4     "POP" shall mean a Network point-of-presence where PSINet equipment 
        will be located and these POPs will be positioned throughout the world

        (non-static-addressed) or non-LAN dial-up customers designated by
        EarthLink as having their principal dial-up access through PSINet's
        dial-up network in the U.S. and Canada.

1.6     "NON-PSINET CUSTOMER" will be EarthLink's dial-up customers 
        designated by EarthLink as having their principal dial-up access
        through another network than PSINet's, whether it be EarthLink's own
        network, or another of EarthLink's network vendors.

1.7     "CUSTOMER" will be a customer of EarthLink, whether a "PSINet 
        Customer" or "Non-PSINet Customer".

2.      INTERNET CONNECTION SERVICES.

2.1     GENERAL. PSINet agrees to provide Purchaser with dialup (also call 
        "switched") telephone connection services for Purchaser's Customers to
        access the Network and the Internet. Purchaser and its Customers may
        access the Network from any PSINet POP in the United States and Canada.
        The fees to be paid by Purchaser to PSINet for such access services are
        set forth in Section 5.1.

2.2     PROVISION OF ACCESS. Throughout the term of this Agreement, PSINet
        shall provide Purchaser's Customers with the right to access at 
        speeds up to 128 Kbps using standard telephone and ISDN lines, and 
        use its Network at the levels then provided and supported by PSINet
        ("Access"). A recent estimated listing of Network POPs can be retrieved
        by sending electronic mail at '[email protected]' or through access to 
        PSINet's world-wide web site at 'http://www.psi.net'. PSINet reserves 
        the right to install new POPs and/or to close existing POPs as it, in 
        its sole discretion, deems appropriate. In the event PSINet deems it 
        necessary to close an existing POP, PSINet shall provide Purchaser with
        sixty (60) days written notice thereof. Purchaser may order such Access
        on behalf of its present or future Customers and there shall be no 
        limit on the number of Customers who may use the Network; provided, 
        however, subject to the Service Level Agreement in Section 3.7 that 
        PSINet may refuse service to Purchaser because there is insufficient 
        capacity on the Network or in the POP to provide the Access amount 
        requested.

2.2.1   TERMINATION OF ACCESS. PSINet shall terminate the Access rights of 
        any Purchaser Customer as soon as is reasonably practicable upon written
        notice from Purchaser to do so or upon mutually agreed upon electronic
        process with receipt confirmed, but shall have no liability in
        connection therewith.

<PAGE>

2.2.2   ISDN SERVICE. PSINet shall make ISDN 64k and 128k Internet connection 
        services available to Purchaser for Purchaser's dial-up customers. The
        fees to be paid by Purchaser for such services are set forth in Section
        5.1.

3.      PURCHASER OBLIGATIONS.

3.1     PURCHASER RESPONSIBILITY FOR ITS CUSTOMERS. Purchaser shall be 
        responsible for all Customer support, pricing and service plans, billing
        and collections with respect to its own Customers.

3.2     PURCHASER CONNECTION TO THE NETWORK. Purchaser may provide, at its 
        own expense, the telecommunications circuit for its connection to the
        Network which shall run between the best suited PSINet POP (as
        determined by PSINet) and the Purchaser's operations center (which
        includes the local telephone company or Competitive Access Provider
        circuits). In addition, Purchaser may provide an estimate of the traffic
        it anticipates between Purchaser's network and PSINet's Network.

3.3     [INTENTIONALLY LEFT BLANK]

3.4     [INTENTIONALLY LEFT BLANK]

3.5     CUSTOMER EQUIPMENT. PSINet shall not be responsible for the 
        installation, operation or maintenance of any computer equipment or
        computer software programs used by any Purchaser Customer.

3.6     OPTIONAL PEERING. In addition to the connection of Purchaser's 
        network and PSINet's Network as set forth in Section 3.2, Purchaser may,
        but shall not be obligated to, provide telecommunications circuits
        interconnecting Purchaser's network with PSINet's network at a location
        agreed upon by the parties and, from time to time, in other locations.
        The parties will use these circuits only for traffic originating within
        one party's network (or the networks of its Customers) and destined only
        to the other party's network (or the networks of its Customers).

3.7     SERVICE LEVEL AGREEMENT. Purchaser will maintain a 90 day rolling 
        forecast of predicted PSINet Customers at each POP, and provide this
        forecast to PSINet as requested. This forecast will include comparative
        historical numbers as they become available. Except as set forth in the
        section below, Purchaser will have no liability for the inaccuracy of
        this forecast.

        The number forecasted at each POP 60 days prior to a given day will 
        give rise to mutual obligations for that day at that POP as follows:

             1. If the number of actual PSINet Customers for a given POP on a 
                given day is greater than 110% of the number forecasted, no
                penalty or Service Level Agreement ("SLA") applies.

Network Access Agreement           Page: 3                               7/24/96

<PAGE>

             2. If the number of PSINet Customers on a given day is less than 
                90% of the number forecasted, Purchaser will pay a penalty of *%
                above the applicable fees for that POP for that day.

             3. For each POP where neither 1 nor 2 applies, PSINet will be 
                required to provide 99.5% availability for dial-in-access. For
                each day less than 99.5% availability is provided, Purchaser
                will be credited *** ********** ********* ***** ****** *** ****
                ****** ******** ******** ********* ******* ** **** ***. For
                example, if on April 2, 1997 Purchaser forecasted that there
                would be 910 PSINet Customers on the Smalltown POP, and the
                actual number of PSINet Customers on the Smalltown POP on 
                June 1, 1997 were 1000, and the total number of PSINet
                Customers on June 30, 1997 were 155,001, and the availability of
                Smalltown POP fell below 99.5% on June 1, 1997, Purchaser would
                be credited ***** * ******* ** ******* for that service lapse.

        Purchaser will provide at least 60 days' notice if it decides to 
        build a POP to service existing PSINet Customers in a particular city,
        provided the existing PSINet Customers for that POP exceed 5,000
        customers.

4.      PSINET OBLIGATIONS.

4.1     QUALITY OF SERVICE. PSINet shall provide to Purchaser (for its 
        Customers) Internet connection services that meet reasonable commercial
        standards, including, without limitation, with respect to accessibility,
        latency, packet loss, and throughput. For example, PSINet shall maintain
        throughput of 80% of nominal port speed (e.g. 23 Kbps for a 28.8 Kbps
        connection, 51 Kbps for a 64 Kbps single ISDN connection) 90% of the
        time. PSINet shall keep and maintain its Network in good condition and
        repair. The Network shall be properly maintained, serviced and upgraded
        by PSINet as it, in its sole discretion, shall determine is necessary in
        order to ensure connectivity to Purchaser Customers.

4.1.1   REPORTS AND INFORMATION REGARDING SERVICE.

4.1.1.1 ACCESS TO NETWORK MONITORING SYSTEMS. PSINet shall provide Purchaser 
        with read-only access to all applicable network monitoring systems used
        by PSINet to monitor its network. Such access will permit Purchaser to
        determine availability at each POP.

4.1.1.2 PSINET NETWORK OUTAGES. PSINet shall provide to Purchaser prompt 
        notification of any PSINet network outages that affect Purchaser's 
        Customers. When possible, at least three days advance notice of planned
        outages shall be given to Purchaser so that Purchaser's Customers may be
        alerted.

4.1.1.3 SNMP ACCESS. PSINet shall provide to Purchaser SNMP access to 
        PSINet's Network (i.e., direct read-only access to the dialup equipment,
        as well as, if

possible, the devices used to provide backbone transport) with respect to 
Purchaser's dial-up Customers, as soon as such access is practicable.

4.1.1.4  TECHNICAL INTERCONNECT. PSINet will develop a means to allow PSINet 
Customers to be authenticated via Purchaser's RADIUS serves in Purchaser's 
data center. PSINet Customers will be set up by Purchaser to log into 
PSINet's network with an "ELN/" in front of their username.

PSINet will provide real-time monitoring capabilities for Purchaser's 
technical and support staff to track access of PSINet Customers on PSINet's 
network. PSINet will provide 24X7 NOC-to-NOC support for Purchaser.

5.  PRICE AND PRICING TERMS.

5.1  CHARGES.  Purchaser will pay PSINet the applicable monthly fee for each 
PSINet Customer who has access to PSI's network during a particular month. 
Where the PSINet Customer did not have access for the entire month, the 
monthly fee will be prorated. Where the PSINet Customer has signed up AND 
canceled Purchaser's service within an initial 30 day period, no monthly fee 
will be due PSINet for that PSINet Customer.

In addition to PSINet Customers, Purchaser will have customers who use 
Purchaser's own dial-up TCP/IP network or other networks provided by vendors 
other than PSINet. Purchaser will make reasonable efforts to ensure that it 
segregates customers to one network or another in a given billing month. 
However, for such Non-PSINet customers who access the PSINet network in a 
given month, PSINet will charge Purchaser $**** for each day such Non-PSINet 
customer accesses the PSINet network, but no more than the applicable flat 
monthly rate for each PSINet Customer.

For each PSINet customer in the United States, monthly charges to Purchaser 
shall be based upon the number of PSINet Customers, calculated at the end of 
each month, as follows:

      TIER       PRICE       VOLUME
       A         ******      0-10,000
       B         *****       10,001-125,000
       C         *****       125,001 +

For each PSINet Customer in Canada, the monthly charge to the Purchaser will 
be $**** more (U.S. dollars) than the price noted above. Canadian and US 
Customers will count together cumulatively for the purpose of determining

</TABLE>

The applicable base charges above are applied to all PSINet Customers 
irrespective of the rate that previously was applied to 
each group of Customers. That is, when the volume threshold for a certain 
tier is reached, Purchaser shall be entitled to the pricing for that tier for 
all PSINet Customers (e.g. at and below that tier volume).

ISDN Service:  Charges will be the same as above for ISDN 64K connection 
services. Charges will be twice the 64K rate for 128K service.

5.1.1  MOST FAVORED NATION.  PSINet commits that the pricing provided to 
Purchaser will be at least as low as for comparable volume levels and similar 
services as that provided any other PSINet customer.

5.2  ADJUSTMENTS TO BASE CHARGE.  When the number of PSINet Customers exceeds 
500,000, PSINet and purchaser will begin good faith negotiations on new 
pricing terms.

5.3  MINIMUM COMMITMENT: On January 1, 1997, Purchaser's minimum monthly 
commitment to PSINet shall become $******* per month for each month of 1997. 
This minimum commitment will expire on December 31, 1997.

5.4  TAXES. Purchaser shall be liable for and shall reimburse PSINet for all 
taxes and related charges however designated, imposed in connection with or 
arising from the provision of access to the PSINet network by Purchaser or 
its Customers. This clause is intended to cover "per-subscriber" or 
"per-byte" charges targeted at the Internet traffic of Purchaser or its 
customers. These taxes will not include the following:

         -Taxes on T1 or PRI local loop lines to PSINet POPs
         -Taxes on PSINet's equipment or facilities
         -Taxes on PSINet's dedicated data circuits

5.5  INVOICES. PSINet shall invoice Purchaser monthly in arrears for all 
charges under this Agreement. Except where inapplicable per Section 5.9, all 
invoices will be payable within (30) days of receipt of invoice. 
Delinquent payments are subject to a late payment charge at the annualized rate 
of prime plus four percent computed monthly (4%), or portion thereof, of the 
amount due (but not to exceed the maximum lawful rate). In the event 
Purchaser shall fail to pay PSINet any amount due under this Agreement for a 
period of forty (40) days, PSINet, in addition to charging applicable 
delinquency fees, may discontinue providing to Purchaser and its Customers 
upon seven (7) days' prior written notice to Purchaser. PSINet shall resume 
providing Access immediately upon receipt of 


* - Redacted Material subject to Confidential Treatment Application


                                      6

<PAGE>

such payment, and in such event Purchaser shall pay PSINet a reasonable 
reconnection fee. However, Purchaser shall not be deemed to be delinquent, 
nor may access be terminated, until Purchaser has exhausted the line of 
credit described in Section 5.9

5.6  CUSTOMER CHARGES.  Purchaser is solely responsible for establishing and 
collecting its Customer charges for services it offers its customers through 
the Network and for preparing and mailing invoices to its Customers. 
Purchaser is responsible for payment of the total amounts invoiced it by 
PSINet regardless of whether Purchaser is paid by its Customers.

5.7  MARKETING REFERRALS.  Until January 1, 1997, PSINet will provide 
Purchaser with the first opportunity to sell to all leads calling into PSINet 
inquiring about or seeking the purchase of non-dedicated, dial up Internet 
access. At Purchaser's discretion, such leads will be transferred 
telephonically directly to Purchaser's telemarketing group, where Purchaser 
will attempt to sell the lead a dial-up access account. Purchaser will pay 
PSINet a one-time bounty of $***** for each lead that signs up for services 
and remains a paying customer for more than 60 days. By 30 days after the end 
of each month, Purchaser shall provide PSINet an accounting of the number of 
leads received and the number successfully converted into sign-ups, along 
with payment of applicable bounties.

5.8  USAGE REPORTS.  PSINet will provide full usage reports at the end of 
each day. These reports shall include detailed accounting of each Purchaser 
network customer (PSINet Customer or Non-PSINet Customer) login to PSINet's 
network. Additionally, PSINet and Purchaser will work to set up a system 
whereby Purchaser can track usage (connects and disconnects) in real time.

5.9  ADDITIONAL CONSIDERATION.  In exchange for Purchaser issuing to PSINet 
the sum of 200,000 warrants to purchase the same number of shares of common 
stock of Purchaser (or the equivalent thereof to compensate for any changes 
in the capital structure of Purchaser between the time of grant and the time of
exercise by PSINet, with 4 years to exercise), the exercise price to be the fair
market value at the time of grant, PSINet will provide the following credit 
and rental facilities to Purchaser:

         1. A credit line for Purchaser's payables to PSINet hereunder 
according to these terms:

         - Up to $5,000,000
         - Accruing interest at prime plus 4% per annum
           Applied to payables beyond the 30 day payment term described above 
         - Balloon payment at the end of the initial term hereof

         2. A commitment to a rental facility for $5,000,000 of equipment 
(owned or leased by PSINet) for deployment in Purchaser's network. Such 
rental charges shall include all costs, such as service maintenance, and 
shall be for equipment agreed to in advance by the parties.

                   The equipment shall be Sun servers, Ascend Max Hubs and 
                   other network equipment. The maximum initial value of 
                   assets being rented shall not exceed $5,000,000 in value.

                   Rental agreement shall include Fair Market Value buyout 
                   provisions, a 3-year term and an effective rate of not 
                   more than prime plus 3% per annum.

                   Monthly rental payments will be due beginning 30 days 
                   after funding of Purchaser's IPO, or February 1, 1997,
                   whichever is sooner.

        Terms of Purchaser's warrants shall include a term of 4 years; 
        will provide for appropriate adjustments to the exercise price 
        and number of shares which may be purchased in the event of stock 
        splits, dividends and the like. In addition, PSINet shall receive 
        registration rights in respect to the shares (the "Shares") issuable 
        upon the exercise of the Warrants as described in the attached 
        Exhibit "A". PSINet shall be entitled to receive financial 
        information regarding the Company for so long as PSINet holds the 
        Shares.

6.      TERM/EXTENSIONS/TERMINATION. The term of this Agreement shall be two 
        (2) years, commencing on August 1, 1996 and ending July 31, 1998, 
        and, unless either party notifies the other in writing not less than 
        one-hundred eighty (180) days prior to the end of the initial term or 
        any extension thereof, this Agreement shall be automatically renewed 
        annually thereafter for a period of one year. Notwithstanding the 
        foregoing, such termination notice shall not be given by either party
        prior to December 31, 1997.

        Either party may terminate this Agreement if such other party has 
        materially breached this Agreement and has failed to cure such breach 
        within thirty (30) days after receiving written notice of such 
        breach; provided, however, that this notice period shall not apply to 
        a termination by PSINet in accordance with the provisions of Section 
        5.5.

7.      WARRANTIES EXCLUDED. EXCEPT AS EXPRESSLY PROVIDED HEREIN, PSINet 
        MAKES NO WARRANTIES IN CONNECTION WITH ITS NETWORK OR THE PROVISION 
        OF ACCESS AS CONTEMPLATED HEREIN, WHETHER WRITTEN OR ORAL, STATUTORY, 
        EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION THE WARRANTY OF 
        MERCHANTABILITY AND THE WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE 
        OR USE. PURCHASER'S SOLE AND EXCLUSIVE REMEDY SHALL BE PSINET'S 
        OBLIGATION TO ADJUST THE FEES PAYABLE BY PURCHASER AS SET FORTH 
        ELSEWHERE HEREIN.

8.      LIMITATION OF LIABILITY. NOTWITHSTANDING ANYTHING CONTAINED IN THIS 
        AGREEMENT TO THE CONTRARY, THE PARTIES AGREE THAT NEITHER PARTY SHALL 
        IN ANY EVENT BE LIABLE TO THE OTHER PARTY OR ANY OTHER PERSON FOR ANY

        KIND OR NATURE WHATSOEVER, REGARDLESS OF THE FORESEEABILITY THEREOF, 
        ARISING OUT OF THE PROVISION OF ACCESS OR IN ANY WAY ARISING OUT OF 
        THIS AGREEMENT, WHETHER IN AN ACTION ARISING OUT OF BREACH OF 
        CONTRACT, BREACH OF WARRANTY, DELAY, NEGLIGENCE, STRICT TORT 
        LIABILITY, PATENT MATTERS OR ANY OTHER THEORY. NO ACTION OR 
        PROCEEDING AGAINST EITHER PARTY MAY BE COMMENCED MORE THAN TWO YEARS 
        AFTER THE SERVICES ARE RENDERED. THIS CLAUSE SHALL SURVIVE FAILURE OF 
        AN EXCLUSIVE REMEDY. EITHER PARTY'S TOTAL LIABILITY FOR GROSS 
        NEGLIGENCE DURING THE LIFETIME OF THIS AGREEMENT SHALL IN NO EVENT 
        EXCEED FIVE HUNDRED THOUSAND DOLLARS ($500,000) IN THE AGGREGATE.

        transmitted by Purchaser Customers or other acts or omissions of 
        Purchaser and/or its Customers.

10.     CONFIDENTIAL INFORMATION.

10.1    Nondisclosure. If either party acquires Confidential Information of 
        the other, such receiving party shall maintain the confidentiality of 
        the disclosing party's Confidential Information shall use such 
        Confidential Information only for the purposes for which it is 
        furnished and shall not reproduce or copy it in whole or in part, 
        except for use as authorized in this Agreement. Confidential 
        Information shall mean all information of the disclosing party which 
        it treats as confidential or proprietary. Confidential Information 
        shall not include information which is or hereafter becomes generally 
        available to others without restriction or which is obtained by the 
        receiving party without violating the disclosing party's rights under 
        this Article 10 or any other obligation of confidentiality. The terms 
        and conditions of this Agreement shall constitute Confidential 
        Information. The provisions in the Bilateral Nondisclosure Agreement 
        executed between the parties on July 18, 1996 shall survive the 
        execution and termination of this Agreement for any reason.

10.2    Duration. With respect to all Confidential Information, the parties' 
        rights and obligations under this Article shall remain in full force 
        and effect following the termination of this Agreement.

10.3    Ownership. All materials and records which constitute Confidential 
        Information, other than service orders and copies of this Agreement, 
        shall be and remain the property of, and belong exclusively to, the 
        disclosing Party, and the receiving party agrees either to surrender 
        possession of and turn over or to destroy all such Confidential 
        Information which it may possess or control upon request of the 
        disclosing party or upon the termination of this Agreement.

10.4    Injunctive Relief. The parties acknowledge and agree that, in the 
        event of a breach or threatened breach by any party of any provision 
        of this Article 10, the other party will have no adequate remedy in 
        money or damages and, accordingly, shall be entitled to an injunction 
        against such breach. However, no specification in this Section of a 
        specific legal or equitable remedy shall be construed as a waiver or 
        prohibition against any other legal or equitable remedies in the 
        event of a breach of this Article of this Agreement.

10.5    Legal Obligation to Disclose. Each party shall be released from its 
        obligations under this Article 10 with respect to information which 
        such party is required to disclose to others pursuant to obligations 
        imposed by law, rule or regulation; provided, however, that prior to 
        any such required disclosure, if practicable, such party provides 
        written notice to and consults with the other party.

11.     MISCELLANEOUS.

11.1    Independent Parties/No Agency. The relationship of PSINet and 
        Purchaser shall be that of independent third parties. Except as 
        otherwise expressly provided in this Agreement, this Agreement does 
        not constitute either party as the agent or legal representative of 
        the other party and does not create a partnership or joint venture 
        between the parties. Except as otherwise expressly provided in this 
        Agreement, neither party shall have any authority to contract for or 
        bind any other party in any manner whatsoever. This Agreement confers 
        no rights of any kind upon any third party.

11.2    Force Majeure. PSINet shall not be liable for failure to fulfill its 
        obligations hereunder if such failure is due to causes beyond its 
        control, including, without limitation, acts of God, fire, 
        catastrophe, governmental prohibitions or regulations, viruses which 
        did not result from the acts or omissions of PSINet, its employees or 
        agents, national emergencies, insurrections, riots or wars, or 
        strikes, lockouts, work stoppages or other labor difficulties. The 
        time for any performance required hereunder shall be extended by the 
        delay incurred as a result of such act of force majeure, and PSINet 
        shall act with dilligence to correct such force majeure.

11.3    Delays or Omissions. No delay or omission to exercise any right, 
        power or remedy accruing to a party under this Agreement shall impair 
        any such right, power or remedy of such party nor shall it be 
        construed to be a waiver of any such breach or default, or an 
        acquiescence therein, or of or in any similar breach or default 
        thereafter occurring; nor shall any waiver of any single breach or 
        default be deemed a waiver of any other breach or default theretofore 
        or thereafter occurring.  Any waiver, permit, consent or approval of 
        any kind or character on the part of either party of any breach or 
        default under this Agreement, or any waiver on the part of either 
        party of any provisions or conditions of this Agreement must be made 
        in writing and shall be effective only to the extent specifically set 
        forth in such writing. All remedies, either under this Agreement or 
        by law or otherwise afforded to a party, shall be cumulative and not 
        alternative.

11.4  BENEFIT AND ASSIGNMENT. No party hereto shall assign this Agreement, in 
      whole or in part, whether by operation of law or otherwise, without the 
      prior written consent of the other party hereto (which consent shall not 
      be unreasonably delayed or withheld); and any purported assignment in 
      violation of the foregoing shall be void. This Agreement shall be 
      binding upon and shall inure to the benefit of the parties hereto and 
      their respective successors and assigns as permitted hereunder. No

      enforceable only by, the parties hereto or their respective successors 
      and assigns as permitted hereunder.

11.5  ADDITIONAL ACTIONS, DOCUMENTS AND INFORMATION: AUDIT. Each of the 
      parties hereto agrees that it will, at any time, prior to, at or after

      such further documents and instruments and obtain such consents, as may 
      be reasonably requested in order to fully effectuate the purposes, 
      terms and conditions of this Agreement. In addition, PSINet may, at 
      reasonable intervals and upon reasonable notice to Purchaser, either by 
      itself or by its outside audit firm, audit the relevant books, records 
      and electronic data of Purchaser to assure proper payments have been 
      made by Purchaser hereunder. PSINet shall bear the costs of each such 
      audit unless the results of such audit show that Purchaser has 
      underpaid PSINet by 5% or more, in which case the cost of such audit 
      and the following correctional audit shall be borne by Purchaser.

    B. The parties wish to amend the Original Agreement to reflect certain 
revisions as discussed between the parties.

NOW, THEREFORE, in consideration of the mutual obligations in this Amendment and
for other good consideration, the receipt and sufficiency of which are
acknowledged, the parties to this Amendment agree as follows:

SECTION III. COMMENCEMENT OF TERM AND POSSESSION OF PREMISES

A.  LEASE COMMENCEMENT DATE                         SEE ADDENDUM SECTION XXXV.B.

    The Term of the Lease shall commence on the Lease Commencement Date (as 
    extended only pursuant to Section III.C. below, if applicable), and shall
    continue, subject to earlier termination as provided herein, until the
    Expiration Date (as extended only pursuant to subsection C. below).

B.  COMPLETION OF TENANT IMPROVEMENTS AND POSSESSION OF PREMISES

    Upon execution of this Lease by the parties, Landlord shall proceed to 
    complete the tenant improvements in the Premises described as "Landlord's
    Work" in the "Construction Work Letter" attached hereto and incorporated
    herein as EXHIBIT C. At the time such work has been substantially completed
    in accordance with the Construction Work Letter(2) ("Substantial
    Completion"), Landlord shall notify Tenant thereof and Tenant shall take
    possession of the Premises on the Lease Commencement Date. In the event
    permission is given to Tenant to enter or occupy all or a portion of the
    Premises prior to the Lease Commencement Date, such occupancy shall be
    subject to all of the terms and conditions of this Lease.  Tenant shall
    complete all tenant improvements described as "Tenant's Work" in EXHIBIT C
    hereto, and shall open the Premises for business, on or before the Lease
    Commencement Date. Any professional fees or costs and expenses incurred by
    Landlord in reviewing plans and specifications for Tenant's Work shall be

C.  EXTENSION OF LEASE COMMENCEMENT DATE

    If the Premises are not ready for occupancy by Tenant on the original 
    Lease Commencement Date specified in Section I. due to one or more delays
    caused by Landlord or caused by matters beyond the control of Landlord, this
    Lease and the obligations of Landlord and Tenant hereunder shall
    nevertheless continue in full force and effect.  However, in such event
    Landlord and Tenant shall agree on an amendment of the original Lease
    Commencement Date to reflect such delay or delays and shall, in each
    instance, execute and attach hereto an amendment in the form of that
    attached as EXHIBIT F hereto stating such amended Lease Commencement Date
    and, if applicable, an amended Expiration Date and no rental shall be
    payable by Tenant hereunder until the amended Lease Commencement Date. The
    delay in commencement of the Term and in the accrual of rent described in
    the foregoing sentence shall constitute full settlement of

- ---------------------------
(2) , and any base Building improvements required for Tenant's occupancy of 
    the Premises are substantially completed

(3) credited against the Tenant Allowance (as defined in EXHIBIT C hereto), 
    if available, and otherwise shall be

                                       3

<PAGE>

    all claims that Tenant might otherwise have by reason of the Premises not
    being ready for occupancy on the original Lease Commencement Date specified
    in Section I. above.

    If the Premises are not ready for occupancy by Tenant on the Lease 
    Commencement Date due to one or more delays caused by Tenant, or anyone
    acting under or for Tenant, Landlord shall have no liability for such delay
    and the Lease Commencement Date shall nevertheless begin as of the Lease
    Commencement Date stated in Section I. (as extended only because of
    Landlord's delay pursuant to this subsection C., if applicable).

    (4)

D.  ACCEPTANCE AND SUITABILITY

    Within fifteen (15) days following the date Tenant takes possession of 
    the Premises, Tenant may provide Landlord with a "punch list" which sets
    forth any itemization of any corrective work to be performed by Landlord
    with respect to the Landlord's Work as set forth in the Construction Work
    Letter; provided, however, that Tenant's obligation to pay Monthly Rental as
    provided below shall not be affected thereby. (5)If Tenant fails to submit
    such "punch list" to Landlord within such fifteen (15) day period, Tenant
    agrees that by taking possession of the Premises it will conclusively be
    deemed to have inspected the Premises and found the Premises in satisfactory
    condition. Tenant acknowledges that neither Landlord, nor any agent,
    employee or servant of Landlord, has made any representation with respect to
    the Premises or the Project, or with respect to the suitability of them for
    the conduct of Tenant's business, nor has Landlord agreed to undertake any
    modifications, alterations, or improvements of the Premises or Project,
    except as specifically provided in this Lease.

    TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, LANDLORD HEREBY 
    DISCLAIMS, AND TENANT WAIVES THE BENEFIT OF, ANY AND ALL IMPLIED WARRANTIES,
    INCLUDING IMPLIED WARRANTIES OF HABITABILITY, FITNESS OR SUITABILITY FOR
    PURPOSE, OR THAT THE BUILDING OR THE IMPROVEMENTS IN THE PREMISES HAVE BEEN
    CONSTRUCTED IN A GOOD AND WORKMANLIKE MANNER. TENANT EXPRESSLY ACKNOWLEDGES
    THAT LANDLORD DID NOT CONSTRUCT OR APPROVE THE QUALITY OF CONSTRUCTION OF
    THE BUILDING.

(4) In the event that the Lease Commencement Date fails to occur within sixty 
    (60) days of the Lease Commencement Date specified in Section I. above 
    (which sixty (60) day period shall be extended one day for each day of 
    delay caused by Tenant or force majeure (as defined in Section XXXIII.K. 
    below)), then Tenant's obligation to pay Monthly Rental shall be delayed 
    one day for each day after expiration of such sixty (60) day period (as 
    so extended) and prior to the actual Lease Commencement Date. For 
    example, if the Lease Commencement Date occurs April 1, 1997 (a delay of 
    ninety (90) days), solely as a result of Landlord delay, then Tenant's 
    obligation to pay Monthly Rental shall commence May 1, 1997, 
    notwithstanding the occurrence of the Lease Commencement Date.

(4)  In the event that the Lease Commencement Date fails to occur 
     within sixty (60) days of the Lease Commencement Date specified in 
     Section I. above (which sixty (60) day period shall be extended one day
     for each day of delay caused by Tenant or force majeure (as defined in
     Section XXXIII.K. below)), then Tenant's obligation to pay Monthly Rental
     shall be delayed one day for each day after expiration of such sixty (60)
     day period (as so extended) and prior to the actual Lease Commencement
     Date. For example, if the Lease Commencement Date occurs May 1, 1997 (a
     delay of seventy-six (76) days), solely as a result of Landlord delay,
     then Tenant's obligation to pay Monthly Rental shall commence May 17, 
     1997, notwithstanding the occurrence of the Lease Commencement Date.

(5) Upon receipt of such punch-list, Landlord shall promptly commence to 
    complete the items noted thereon which Landlord agrees are properly included
    on the punch-list, and will use reasonable efforts to complete such items
    within thirty (30) days of receipt of the punch-list.

SECTION IV. RENT

A.   MONTHLY RENTAL

     Commencing on the Lease Commencement Date (subject, however, to any 
     modifications or adjustments specified hereinbelow and/or in the "Rent 
     Schedule" attached hereto as EXHIBIT D) Tenant shall pay to Landlord 
     during the Term, rental for the entire Term in the total amount as set 
     forth in EXHIBIT D payable in monthly installments (the "Monthly Rental") 
     in the amount set forth in EXHIBIT D, which sum shall be payable by 
     Tenant on or before the first day of each month, in advance, without 
     further notice, at the address specified for Landlord in Section I., or 
     such other place as Landlord shall designate, without any prior demand 
     therefor and (7) without any abatement, deduction or setoff 
     whatsoever. Monthly Rental for the first full month of the Term when 
     rental is due shall be paid upon the execution hereof. If the Lease 
     Commencement Date should occur on a day other than the first day of a
     calendar month, or the Expiration Date should occur on a day other than
     the last day of a calendar month, then the rental for such fractional 
     month shall be prorated on a daily basis upon a thirty (30) day calendar
     month.

B.   CONSUMER PRICE INDEX INCREASES

     The Monthly Rental payable by Tenant under this Section IV. shall be 
     increased upon the expiration of the twelfth (12th) calendar month of 
     the Term and upon the expiration of each twelve (12) month period 
     thereafter according to the increase in the "Consumer Price Index", as 
     hereinafter defined; provided, however, that the total rate of 
     increase shall not be less than five percent (5%) per annum compounded 
     annually from the Lease Commencement Date. As used herein, the term 
     "Consumer Price Index" shall mean the Consumer Price Index for all 
     Urban Consumers (all items) as published by the United States 
     Department of Labor, Bureau of Labor Statistics for the _____________ Area.
     The amount of such increase in the Monthly Rental shall be determined by 
     multiplying the Monthly Rental by a fraction, the denominator of which 
     shall be the most recent Consumer Price Index figure published prior 
     to the actual Lease Commencement Date, and the numerator of which 
     shall be the most recent Consumer Price Index figure published prior 
     to the date of such adjustment; provided, however, that in no event 
     shall the Monthly Rental for any month be less than the Monthly Rental 
     for the immediately preceding month. Should Landlord lack sufficient 
     data to determine the adjusted Monthly Rental on the date of any such 
     adjustment, Tenant shall continue to pay the Monthly Rental payable 
     immediately prior to such adjustment date. As soon as Landlord obtains 
     the necessary data, it shall determine the Monthly Rental payable from 
     and after such adjustment date computed on a retroactive basis from 
     the date of such adjustment and shall notify Tenant of the adjustment 
     in writing. Should the Monthly Rental for the period following such 
     adjustment date exceed the amount previously paid by Tenant for such 
     period, Tenant shall forthwith pay the difference to Landlord. If the 
     Consumer Price Index is discontinued or revised during the Term, such 
     other government index or computation with which it is replaced shall 
     be used in order to obtain substantially the same results as would be 
     obtained if the Consumer Price Index had not been discontinued or 
     revised.

- --------------------------
(6)  Notwithstanding the foregoing, Landlord will cure any latent defects in 
     Landlord's Work which are not readily ascertainable upon a thorough 
     walk-through of the Premises, which defects are identified by Tenant in 
     a written notice given to Landlord within six (6) months of the Lease 
     Commencement Date. Moreover, the provisions of this Section III.D. shall 
     not abrogate Landlord's obligations pursuant to Section X.A. below.

C.   RENT AND ADDITIONAL RENT

     As used in this Lease, the term "rent" shall mean Monthly Rental and 
     additional rent, and the term "additional rent" shall mean all other 
     amounts payable by Tenant to Landlord pursuant to this Lease other than 
     Monthly Rental, including without limitation, Tenant's Proportionate 
     Share of Common Operating Costs in excess of the Base Operating Expense. 
     All Monthly Rental and additional rent shall be paid in lawful money of 
     the United States which shall be legal tender at the time of payment. 
     Where no other time is stated herein for payment, payment of any amount 
     payable from Tenant to Landlord hereunder shall be due, and made, within 
     ten (10) days after Tenant's receipt of Landlord's invoice or statement 
     therefor.

           (l) municipal inspection fees or charges; (m) any other costs or

           with generally accepted accounting principles.

     (4)   In the event during all or any portion of any calendar year (9) 
           the Building is not at least ninety five percent (95%)(10) rented 
           and occupied, Landlord (11) may elect to make an appropriate 
           adjustment to the Common Operating Costs for such year, employing 
           sound accounting and management principles, to determine the Common 
           Operating Costs that would have been paid or incurred by Landlord 
           had the Building been ninety five percent (95%)(12) rented and 
           occupied and the amount so determined shall be deemed to have been 
           the Common Operating Costs for such year.

B.         REIMBURSEMENT

           Within a reasonable time before the commencement of each calendar 
           year during the Term, Landlord shall deliver to Tenant a 
           reasonable estimate of the anticipated Common Operating Costs for 
           the forthcoming calendar year. Tenant shall pay to Landlord, as 
           additional rental, commencing on (13) the Lease Commencement Date, 
           and continuing on the first day of each calendar month thereafter, 
           an amount equal to one-twelfth (1/12th) of the product obtained by 
           multiplying (1) the remainder of the then estimated Common 
           Operating Costs less the Base Operating Expense paid by Landlord, 
           times (2) Tenant's Proportionate Share; provided, however, that 
           such amount shall not be less than zero dollars ($0). The estimated 
           monthly charge for Tenant's Proportionate Share may be adjusted 
           periodically by Landlord during the calendar year on the basis of 
           Landlord's reasonably anticipated costs. Any expenditure (14)by 
           Landlord (e.g. resurfacing of parking areas, painting buildings, 
           refurbishing landscaping or walkways and similar items) during the 
           year which was not included in determining the estimated Common 
           Operating Costs, may be billed separately to Tenant according to 
           Tenant's Proportionate Share.

C.  REBATE OR ADDITIONAL CHARGES
    ----------------------------
    Within a reasonable time after the end of each calendar year, 
    Landlord shall furnish to Tenant a statement (each, an "Annual 
    Statement") showing the total Common Operating Costs and Tenant's 
    Proportionate Share of the Common Operating Costs less the Base Operating 
    Expense for the calendar year just ended. Tenant shall have the right, by 
    written notice to Landlord given within (15)thirty (30) days after 
    receipt of an Annual Statement, to protest specific items on the most 
    recent Annual Statement; to be effective, Tenant's notice must state with 
    specificity the item(s) to which Tenant objects. Tenant's failure to 
    object to an Annual Statement as, when and in the manner provided in the 
    preceding sentence shall render such Annual Statement binding on Tenant. 
    Any objections raised by Tenant in Tenant's notice must be resolved 
    within sixty (60) days after the same are raised, unless Landlord agrees 
    otherwise in writing. If the amount of estimated Common Operating Costs 
    less the Base Operating Expense paid by Tenant for any year during the 
    Term exceeds the actual Common Operating Costs less the Base Operating 
    Expense for such year, Landlord shall apply any amounts due to Tenant 
    hereunder to any outstanding amounts due or amounts next coming due from 
    Tenant to Landlord. If the estimated Common Operating Costs less the Base 
    Operating Expense for such year are less than the actual Common Operating 
    Costs less the Base Operating Expense for such year, then Tenant shall pay 
    to Landlord, within thirty (30) days of Tenant's receipt of the Annual 
    Statement, as additional rent, Tenant's Proportionate Share of the 
    difference between the amount of actual Common Operating Costs in excess 
    of the Base Operating Expense and the amount of estimated Common 
    Operating Costs in excess of the Base Operating Expense. In the event the 
    Term of this Lease expires, or this Lease is otherwise terminated, 
    Landlord shall compute and prorate the credit or deficiency up to the 
    date the Lease expired or was terminated and may apply any credit due 
    Tenant to any outstanding amounts due by Tenant hereunder at that time 
    and, at the end of the Lease, so long as Tenant is not then in default, 
    shall(16) refund any excess to Tenant.
    
D.  CONTROL OF COMMON AREAS

    Landlord shall have the sole and exclusive control of the Common 
    Areas, as well as the right to make changes to the Common Areas. 
    Notwithstanding the preceding sentence, Landlord is not responsible for 
    any harm or damage to any of Tenant's officers, agents, or employees as a 
    result of their use of the Common Areas(17). Landlord's rights shall 
    include, but not be limited to, the right to (a) restrain the use of the 
    Common Areas by unauthorized persons, (b) utilize from time to time any 
    portion of the Common Areas for promotional and related matters, 
    (c) temporarily close any portion of the Common Areas for repairs, 
    improvements or alterations, (d) change the shape and size of the Common 
    Areas or change the location of improvements within the Common Areas, 
    including, without limitation, parking areas, roadways and curb cuts, and 
    (e) prohibit access to or use of Common Areas that are designated for the 
    storage of supplies or operation of equipment necessary to operate the 
    Project or Building(18). Landlord may determine the

(16) promptly 

(17) except, subject to Sections XIV.C. and XV.B. below, if and to the extent 
it is determined by a court of competent jurisdiction the same were caused by 
Landlord's gross negligence or willful misconduct.

(18) ; provided, however, Landlord shall not exercise its rights pursuant to 
(b), (c) or (d) above so as to unreasonably interfere with Tenant's use and 
enjoyment of or access to the Premises

                                      8

<PAGE>

    nature, size and extent of the Common Areas as well as make changes to the 
    Common Areas from time to time which, in its (19) opinion, are deemed 
    desirable.

SECTION VI. SECURITY DEPOSIT                 See Addendum Section XXXV.D.

Upon execution of this Lease, Tenant shall deposit with Landlord the Security 
Deposit defined in Section I. above, which shall be held by Landlord as 
security for the performance by Tenant of all terms, covenants and conditions 
of this Lease. It is expressly understood and agreed that such deposit is not 
an advance rental deposit or a measure of Landlord's damages in case of 
Tenant's default. If Tenant defaults with respect to any provision of this 
Lease, including, but not limited to, the provisions relating to the payment 
of rent or the obligation to repair and maintain the Premises or to perform 
any other term, covenant or condition contained herein, Landlord may (but 
shall not be required to), without prejudice to any other remedy provided 
herein or provided by law and without notice to Tenant, use the Security 
Deposit, or any portion of it, to cure the default or to compensate Landlord 
for all damages sustained by Landlord resulting from Tenant's default. Tenant 
shall immediately on demand pay to Landlord a sum equivalent to the portion 
of the Security Deposit so expended or applied by Landlord as provided in 
this paragraph so as to maintain the Security Deposit in the sum initially 
deposited with Landlord. Although the Security Deposit shall be deemed the 
property of Landlord, if Tenant is not in default at the expiration or 
termination of this Lease, Landlord shall return the Security Deposit to 
Tenant. Landlord shall not be required to keep the Security Deposit separate 
from its general funds and Landlord, not Tenant, shall be entitled to all 
interest, if any, accruing on any such deposit. Upon any sale or transfer of 
its interest in the Building, Landlord shall transfer the Security Deposit to 
its successor in interest and thereupon, Landlord shall be released from any 
liability or obligation with respect thereto.

SECTION VII. TENANT'S TAXES

To the extent not covered as a Common Operating Cost, Tenant shall be liable 
for any tax (now or hereafter imposed by any governmental entity) applicable 
to or measured by or on the rents or any other charges payable by Tenant 
under this Lease, including (but not limited to) any gross income tax, gross 
receipts tax or excise tax with respect to the receipt of such rent or other 
charges or the possession, leasing or operation, use or occupancy of the 
Premises, but not including any net income, franchise, capital stock, estate 
or inheritance taxes. If any such tax is required to be paid to the 
governmental taxing entity directly by Landlord, then Landlord shall pay the 
amount due and, upon demand, shall be fully reimbursed by Tenant for such 
payment.

Tenant shall also be liable for all taxes levied against the leasehold held 
by Tenant or against any personal property, leasehold improvements, 
additions, alterations and fixtures placed by or for Tenant in, on or about 
the Premises, Building and Project or constructed by Landlord (20) for Tenant 
in the Premises; and if any such taxes are levied against Landlord or 
Landlord's property, or if the assessed value of such property is increased 
(whether by special assessment or otherwise) by the inclusion therein of 
value placed on such leasehold, personal property, leasehold improvements, 
additions, alterations and fixtures, and Landlord pays any such taxes (which 
Landlord shall have the right to do regardless of the validity thereof), 
Tenant, upon demand, shall fully reimburse Landlord for the taxes so paid by 
Landlord or for the proportion of such taxes resulting from such increase in 
any assessment.

SECTION VIII. USE OF PREMISES

A.  PERMITTED USES

    Tenant shall use the Premises and Common Areas solely for the 
    Permitted Use specified in subsection I.M. above, and for no other 
    use, and under the name specified in subsection I.B. above. Tenant 
    shall, at its own cost and expense, obtain any and all licenses and 
    permits necessary for any such use. Tenant shall not do or permit 
    anything to be done in or about the Premises, Common Areas, Building 
    or Project which will in any way(21) obstruct or interfere with the 
    rights of other tenants or occupants of the Project or injure or annoy them
    or use or allow the Premises to be used for any unlawful purpose, nor 
    shall Tenant cause, maintain or permit any nuisance in, on or about 
    the Premises and Common Areas or permit any odors to emanate from the 
    Premises and intrude upon the Common Areas or the premises of other 
    tenants. Tenant shall not commit or suffer to be committed any waste 
    in or upon the Premises, Common Areas, Building or Project. Tenant 
    shall not do or permit anything to be done in or about the Premises, 
    Common Areas, Building or Project which may render the insurance 
    thereon void or increase the insurance risk thereon. If an increase 
    in any fire and extended coverage insurance premiums paid by Landlord 
    for the Building and Project is caused by Tenant's use and occupancy 
    of the Premises,(22) then Tenant shall pay as additional rental the 
    amount of such increase to Landlord.

B.  COMPLIANCE WITH LAWS

    (23)Tenant shall not use the Premises, Building, Project or Common Areas 
    in any way (or permit or suffer anything to be done in or about the 
    same) which will conflict with any law, statute, ordinance or 
    governmental rule or regulation or any covenant, condition or 
    restriction (whether or not of public record) affecting the Premises, 
    Project or Building, now in force or which may hereafter be enacted 
    or promulgated including, but not limited to, the provisions of any 
    city or county zoning codes regulating the use thereof. Tenant shall, 
    at its sole cost and expense, promptly comply with (a) all laws, 
    statutes, ordinances and governmental rules and regulations, now in 
    force or which may hereafter be in force, applicable to Tenant (24) or
    its use of or business or operations in the Premises, (b) all 
    requirements, and other covenants, conditions and restrictions, now 
    in force or which may hereafter be in force, which affect the 
    Premises, and (c) all requirements, now in force or which may 
    hereafter be in force, of any board of fire underwriters or other 
    similar body now or hereafter constituted relating to or affecting 
    the condition, use or occupancy of the Premises, Building or Project. 
    The judgment of any court of competent jurisdiction or the admission 
    by Tenant in any action against Tenant, whether Landlord be a party 
    thereto or not, that Tenant has violated any law, statute, ordinance, 
    governmental rule or regulation or any requirement, covenant, 
    condition or restriction shall be conclusive of the fact as between 
    Landlord and Tenant. Tenant agrees to fully indemnify Landlord 
    against any liability, claims or damages arising as a result of a 
    breach of the provisions of this subsection by Tenant, and against

- -----------------------
 (21) , in Landlord's reasonable opinion,

 (22) as evidenced by a letter from the insurance company,

 (23) If and to the extent that Landlord's Work or the Common Areas 
      are not in compliance with applicable governmental requirements as in 
      effect and as applied to the Building as of the Lease Commencement 
      Date, Landlord shall, if, as and when required by such applicable 
      governmental authorities, cause Landlord's Work or the Common Areas, 
      as applicable, to comply therewith.

 (24) relating to

                                      10

<PAGE>

    all costs, expenses, fines or other charges arising, therefrom, 
    including, without limitation, reasonable fees and related costs 
    incurred by Landlord in connection therewith, which indemnity shall 
    survive the expiration or earlier termination of this Lease. Without 
    limiting the generality of the foregoing, it is expressly understood 
    and agreed that, subject to (25)performance by Landlord of Landlord's 
    Work described in EXHIBIT C hereto, Tenant is accepting the Premises 
    "AS IS," in its present state and condition, without any 
    representations or warranties from Landlord of any kind whatsoever, 
    either express or implied, with respect to the Premises or the 
    Building, including without limitation the compliance of the Premises 
    or the Building with The Americans With Disabilities Act and the 
    rules and regulations promulgated thereunder, as amended from time to 
    time (the "ADA").(26) Except as otherwise provided for in EXHIBIT C 
    hereto, if Tenant's use of the Premises or operations therein cause 
    Landlord to incur any obligation under the ADA, as reasonably 
    determined by Landlord, then Tenant shall reimburse Landlord for 
    Landlord's costs and expenses in connection therewith. If Tenant's 
    initial use of the Premises is not a "place of public accommodation" 
    within the meaning of the ADA, then Tenant may not thereafter change 
    the use of the Premises to cause the Premises to become a "place of 
    public accommodation." In the event that Tenant desires or is 
    required hereby to make Alterations (as defined below) to the 
    Premises in order to satisfy its obligations under the ADA, then all 
    such Alterations shall be subject to any requirements in the Lease 
    with respect to Alterations of the Premises, and shall be performed 
    at Tenant's sole cost and expense. Except for Alterations to the 
    Premises, Tenant shall have no right whatsoever to make any 
    alterations or modifications to any portion of the Building or its 
    appurtenant facilities. Tenant shall be responsible for insuring that

C.  HAZARDOUS MATERIALS                           SEE ADDENDUM SECTION XXXV.E.

    Tenant covenants and agrees that it shall not cause or permit any 
    Hazardous Material (as defined below) to be brought upon, kept, or 
    used in or about the Premises, Building or Project by Tenant, its 
    agents, employees, contractors or invitees. The foregoing covenant 
    shall not extend to substances typically found or used in general office 
    applications so long as (i) such substances and any equipment which 
    generates such substances are maintained only in such quantities as 
    are reasonably necessary for Tenant's operations in the Premises, 
    (ii) such substances are used strictly in accordance with the 
    manufacturers' instructions therefor, (iii) such substances are not 
    disposed of in or about the Project in a manner which would 
    constitute a release or discharge thereof, and (iv) all such 
    substances and any equipment which generates such substances are 
    removed from the Project by Tenant upon the expiration or earlier 
    termination of this Lease. Any use, storage, generation, disposal, 
    release or discharge by Tenant of Hazardous Materials in or about the 
    Project as is permitted pursuant to this subsection C. shall be 
    carried out in compliance with all applicable federal, state and 
    local laws, ordinances, rules and regulations. Moreover, no 
    hazardous waste resulting from any operations by Tenant shall be 
    stored or maintained by Tenant in or about the Project for more than 
    ninety (90) days prior to removal by Tenant. Tenant shall, annually 
    within thirty (30) days after Tenant's receipt of Landlord's written 
    request therefor, provide to Landlord a written list identifying any 
    Hazardous Materials then maintained by Tenant in the Project, the use 
    of each such Hazardous Material and the approximate quantity of each 
    such Hazardous Material so maintained by Tenant, together with 
    written certification by Tenant stating, in substance, that neither 
    Tenant nor any person for whom Tenant is responsible has released or 
    discharged any Hazardous Materials in or about the Project.

 (26) Notwithstanding the foregoing, but subject to the three 
      immediately succeeding sentences of this subsection B., Landlord 
      shall be responsible, at Landlord's sole cost and expense, for 
      compliance of the Common Areas with the ADA.

   In the event that Tenant proposes to conduct any use or to operate any 
   equipment which will or may utilize or generate a Hazardous Material other 
   than as specified in the first paragraph of this subsection, Tenant shall 
   first in writing submit such use or equipment to Landlord for approval. No 
   approval by Landlord shall relieve Tenant of any obligation of Tenant 
   pursuant to this subsection, including the removal, clean-up and 
   indemnification obligations imposed upon Tenant by this subsection. Tenant 
   shall, within five (5) days after receipt thereof, furnish to Landlord copies
   of all notices or other communications received by Tenant with respect to any
   actual or alleged release or discharge of any Hazardous Material in or 
   about the Premises or the Project and shall, whether or not Tenant receives 
   any such notice or communication, notify Landlord in writing of any discharge
   or release of Hazardous Material by Tenant or anyone for whom Tenant is 
   responsible in or about the Premises or the Project. In the event that Tenant
   is required to maintain any Hazardous Materials license or permit in 
   connection with any use conducted by Tenant or any equipment operated by 
   Tenant in the Premises, copies of each such license or permit, each renewal 
   or revocation thereof and any communication relating to suspension, renewal 
   or revocation thereof shall be furnished to Landlord within five (5) days 
   after receipt thereof by Tenant. Compliance by Tenant with the two 
   immediately preceding sentences shall not relieve Tenant of any other 
   obligation of Tenant pursuant to this subsection.

   Upon any violation of the foregoing covenants, Tenant shall be obligated, at 
   Tenant's sole cost, to clean-up and remove from the Project all Hazardous 
   Materials introduced into the Project by Tenant or any person or entity for
   whom Tenant is responsible. Such clean-up and removal shall include all 
   testing and investigation required by any governmental authorities having 
   jurisdiction and preparation and implementation of any remedial action plan 
   required by any governmental authorities having jurisdiction. All such 
   clean-up and removal activities of Tenant shall, in each instance, be 
   conducted to the satisfaction of Landlord and all governmental authorities 
   having jurisdiction. Landlord's right of entry pursuant to Section XI. shall
   include the right to enter and inspect the Premises for violations of 
   Tenant's covenants herein.

   Tenant shall indemnify, defend and hold harmless Landlord, its partners, and
   its and their successors, assigns, partners, officers, employees, agents, 
   lenders and attorneys from and against any and all claims, liabilities, 
   losses, actions, costs and expenses (including attorneys' fees and costs of 
   defense) incurred by such indemnified persons, or any of them, as the result
   of (A) the introduction into or about the Project by Tenant or anyone for 
   whom Tenant is responsible of any Hazardous Materials, (B) the usage, 
   storage, maintenance, generation, disposition or disposal by Tenant or
   anyone for whom Tenant is responsible of Hazardous Materials in or about the
   Project, (C) the discharge or release in or about the Project by Tenant or 
   anyone for whom Tenant is responsible of any Hazardous Materials, (D) any 
   injury to or death of persons or damage to or destruction of property 
   resulting from the use, introduction, maintenance, storage, generation, 
   disposal, disposition, release or discharge by Tenant or anyone for whom 
   Tenant is responsible of Hazardous Materials in or about the Project, and 
   (E) any failure of Tenant or anyone for whom Tenant is responsible to 
   observe the foregoing covenants of this subsection.

   Upon any violation of the foregoing covenants, Landlord shall be entitled to 
   exercise all remedies available to a landlord against a defaulting tenant, 
   including but not limited to those set forth in Section XX. Without limiting 
   the generality of the foregoing, Tenant expressly agrees that upon any 
   such violation Landlord may, at its option, (I) (27)immediately terminate 
   this Lease or (II) (28)continue this Lease in effect until 

____________________

   (27) which is not cured within the applicable cure period and, at Landlord's
        sole option, upon the third or subsequent violation of any one or more 
        of the foregoing covenants (regardless of whether any prior violations 
        were cured within any applicable cure period),

   (28) upon any such violation,

   compliance by Tenant with its clean-up and removal covenant notwithstanding 
   any earlier expiration date of the term of this Lease. No action by Landlord
   hereunder shall impair the obligations of Tenant pursuant to this subsection.

   sense and shall include any petroleum based products, pesticides, paints and
   solvents, polychlorinated biphenyl, lead, cyanide, DDT, acids, ammonium 
   compounds and other chemical products and any substance or material defined 
   or designated as hazardous or toxic, or other similar term, by any federal, 
   state or local environmental statute, regulation, or ordinance affecting the 
   Premises, Building or Project presently in effect or that may be promulgated

A. STANDARD BUILDING SERVICES AND REIMBURSEMENT BY TENANT         SEE ADDENDUM
                                                    SECTIONS XXXV.C.(2) AND F.

   So long as Tenant is not in default hereunder (including any default of a 
   type described in clauses (4) - (6) of Section XX.A. below), Landlord agrees
   to make available to the Premises, during the Building's normal business 
   hours of 7:00 a.m. to 6:00 p.m. Monday through Friday and 8:00 a.m. to 
   12:00 p.m. on Saturday (holidays excepted), which hours are subject to change
   from time to time as reasonably determined by Landlord, such heat and air 
   conditioning (hereinafter "HVAC"), water and electricity, as may be
   required in Landlord's (32)judgment for the comfortable use and occupation
   of the Premises for general office purposes and at a level which is usual 
   and customary in similar office buildings in the area where the Project is
   located, all of which shall be subject to the Rules of the Building as
   well as any governmental requirements or standards relating to, among other
   things, energy conservation. Tenant agrees to pay, as a Common Operating
   Cost in accordance with Section V. above, Tenant's Proportionate Share in
   excess of the Base Operating Expense of the full cost of all utilities
   supplied to the Premises, together with any taxes thereon; provided, 
   however, if(33) any such service or utilities (34)are separately metered to 
   the Premises, Tenant shall pay the cost thereof in a timely manner directly 
   to the utility company providing such service. Tenant's obligations in this 
   Section regarding utilities include, but are not limited to, initial 
   connection charges, all charges for gas, water and electricity used on the 
   Premises, and for all electric light lamps or tubes. If any such utility or 
   service is not separately metered to the Premises, Tenant shall be required 
   to pay any increased cost, as additional rent, of any such utility and 
   service, including without limitation water, electricity and HVAC, resulting 
   from any use of the Premises at any time other

   and services as reasonably determined by Landlord or any unusual or
   non-customary use beyond that which Landlord has agreed to make available
   as described above, or resulting from special electrical, cooling and
   ventilating needs created in certain areas by telephone equipment,
   computers and other similar equipment or uses. If the Building is designed
   for individual tenant operation of the HVAC, Tenant agrees to pay the cost
   of operating the HVAC at any time other than the schedule of hours for
   providing the same set forth above, which cost may include the operation
   of the HVAC for space located outside the Premises when such space is
   serviced concurrently with the operation of the HVAC for the benefit of
   the Premises.

B. LIMITATION ON LANDLORD'S OBLIGATIONS

   Landlord shall not be in breach of its obligations under this Section unless
   Landlord fails to make any repairs or perform maintenance which it is
   obligated to perform hereunder and such failure persists for an 
   unreasonable time after written notice of a need for such repairs or
   maintenance is given to Landlord by Tenant. Landlord shall be not liable 
   for and Tenant shall not be entitled to any abatement or reduction of rent by
   reason of Landlord's failure to furnish any of the foregoing when such 
   failure is caused by accidents, breakage, repairs, strikes, brownouts, 
   blackouts, lockouts or other labor disturbances or labor disputes of any 
   character, or by any other cause, similar or dissimilar, beyond the 
   reasonable control of Landlord, nor shall such failure under such 
   circumstances be construed as a constructive or actual eviction of Tenant. 
   (35)Landlord shall not be liable under any circumstances for loss or 
   injury to property or business, however occurring, through or in 
   connection with or incidental to Landlord's failure to furnish any of said 
   service or utilities.

C. EXCESS SERVICE

   Tenant shall not, without the written consent of Landlord, use any 
   apparatus or device in the Premises, including, without limitation,
   electronic data processing machines, punch card machines or machines
   using in excess of one hundred twenty (120) volts or which consumes
   more electricity than is usually furnished or supplied for the Permitted
   Use of the Premises, as determined by Landlord. Tenant shall not consume
   water or electric current in excess of that usually furnished or supplied
   for the use of the Premises (as determined by Landlord), without first
   procuring the written consent of Landlord, which Landlord may refuse.
   The excess cost (including any penalties for excess usage) for such water
   and electric current shall be established by an estimate made by a utility
   company or independent engineer hired by Landlord at Tenant's expense
   and Tenant shall pay such excess costs each month with the Monthly Rental.
   All costs and expenses of modifying existing equipment, cables, lines, etc.
   or installing additional equipment, cables, lines, etc. to accommodate such
   excess usage or use by Tenant of such apparatus or device shall be borne 
   by Tenant.




____________________

   (35) If, as a result of Landlord's negligence or willful misconduct,
        utility service to the Premises is interrupted and continues
        interrupted for a period of in excess of three (3) consecutive
        business days after written notice thereof is given to Landlord by 
        Tenant (which three (3) business day period shall be extended by 
        force majeure events described in Section XXXIII.K. below) and which 
        interruption materially prohibits the use of the Premises for the 
        Permitted Use, then Monthly Rental and Tenant's obligation to pay 
        Common Operating Costs shall abate from and after expiration of such 
        three (3) business day period (as so extended) until service is 
        restored (regardless of whether it is later interrupted) if and to 
        the extent that Tenant's ability to conduct business within the 
        Premises is materially and adversely affected by the interruption.

D.   SECURITY SERVICES

     Certain security measures (both by electronic equipment and personnel)
     may be provided by Landlord in connection with the Building and Common
     Areas. However, Tenant hereby acknowledges that such security is intended
     to be only for the benefit of the Landlord in protecting its property
     from fire, theft, vandalism and similar perils and while certain
     incidental benefits may accrue to the Tenant therefrom, such security is
     not for the purpose of protecting either the property of Tenant or the
     safety of its officers, employees, servants or invitees. By providing
     such security, Landlord assumes no obligation to Tenant and shall have no
     liability arising therefrom. If, as a result of Tenant's occupancy of the
     Premises, Landlord in its sole (36)discretion determines that it is
     necessary to provide security or implement additional security measures
     or devices in or about the Building or the Common Areas, Tenant shall be
     required to pay, as additional rent, the cost or increased cost, as the
     case may be, of such security.

     shall not be required to make any repairs that are the obligation of any 
     other tenant or occupant within the Building or Project or repairs for 
     damage caused by any negligent or intentional act or omission of Tenant 
     or any person claiming through or under Tenant or any of Tenant's 
     employees, suppliers, shippers, customers or invitees, in which event 
     Tenant shall repair such damage at its sole cost and expense. Tenant 
     hereby waives and releases its right to make repairs at Landlord's expense

     thereof then Tenant may, after expiration of such five (5) business day
     period, provide Landlord with a second notice of such failure, specifying
     what Tenant proposes as the nature and cost of the cure thereof. If
     Landlord fails to commence to cure such failure within five (5) business
     days after receipt of Tenant's second notice, Tenant may perform the cure
     identified in Tenant's second notice and Landlord shall reimburse to
     Tenant the out-of-pocket costs incurred by Tenant in so

have the right to use any and all means which Landlord may deem proper to 
open such doors in the event of an emergency. Any entry to the Premises or 
portions thereof obtained by Landlord by any of said means, or otherwise, 
shall not under any circumstances be

construed or deemed to be a forcible or unlawful entry into, or a detainer of, 
the Premises, or an eviction, actual or constructive, of Tenant from the 
Premises, or any portion thereof.

SECTION XII.  ALTERATIONS, ADDITIONS AND TRADE FIXTURES

Tenant shall not make any alterations, additions or improvements to the 
Premises, or any part thereof, whether structural or nonstructural 
(hereafter "Alterations"), without Landlord's prior written consent(52). In 
order to obtain Landlord's preliminary consent, which preliminary consent may 
be given or denied(53) in Landlord's sole discretion,(54) Tenant shall submit 
such information as Landlord may require, including without limitation plans 
and specifications for the Alterations. Any professional fees or other costs 
and expenses incurred by Landlord in reviewing such plans and specifications 
shall be paid to Landlord by Tenant as additional rent upon demand. After 
Landlord gives preliminary consent, in order to obtain Landlord's final 
consent, which consent may not be unreasonably withheld, Tenant shall then 
submit (i) permits, licenses, bonds, and the construction contract, all in 
conformance with the plans and specifications preliminarily approved by 
Landlord; (ii) evidence of insurance coverage in such types and amounts and 
from such insurers as Landlord deems satisfactory; and (iii) such other 
information as Landlord deems reasonably necessary. The construction contract 
shall, at a minimum, require the general contractor and all subcontractors to 
obey the rules and regulations of the Building and Project. All Alterations 
shall be done in a good workmanlike manner by qualified and licensed 
contractors or mechanics, as approved by Landlord. In no event shall any 
Alterations affect the structure of the Building or its exterior appearance. 
All Alterations made by or for Tenant (other than Tenant's moveable trade 
fixtures), shall, unless Landlord expressly requires or agrees otherwise in 
writing, immediately become the property of Landlord, without compensation to 
Tenant, but Landlord has no obligation to repair, maintain or insure those 
Alterations. Carpeting, shelving and cabinetry are considered improvements of 
the Premises and not movable trade fixtures, regardless of how or where 
affixed. No Alterations will be removed by Tenant from the Premises either 
during or at the expiration or earlier termination of the Term, and they 
shall be surrendered as a part of the Premises unless Landlord has required 
that Tenant remove them. At Landlord's discretion, Alterations are subject to 
removal by Tenant and at Tenant's sole cost and expense(55). Upon any such 
removal, Tenant shall repair any damage caused to the Premises thereby, and 
shall return the Premises to the condition they were in prior to installation 
of such Alterations so removed. Tenant shall indemnify, defend and keep 
Landlord free and harmless from and against all liability, loss, damage, 
cost, attorneys' fees and any other expense incurred on account of claims by 
any person performing work or furnishing materials or supplies for Tenant or 
any person claiming under Tenant. Landlord may require Tenant to provide 
Landlord, at Tenant's sole cost and expense, a lien and completion bond in an 
amount equal to one and one-half times the estimated cost of such 
improvements, to insure Landlord against any liability for mechanic's liens 
and to insure completion of the work. Landlord shall have the right at all 
times to post on the Premises any notices permitted or required by law, or 
that Landlord shall deem proper, for the protection of Landlord, the 
Premises, the Building and the Project, and any other party having an 
interest therein, from

- -------------------------

52   except that Tenant may make, without Landlord's prior consent but 
     subject to the remaining provisions of this Section XII., non-structural 
     Alterations to the Premises which do not affect the Building systems or 
     the floor plan of the Premises, which do not cost, in the aggregate, 
     over a twelve (12) month period in excess of $50,000.00 and which are 
     consistent, in terms of quality and design, with the initial Tenant 
     Improvements and Tenant's Work in the Premises

53   , in the case of Alterations which affect Building structure and/or
     systems or the floor plan of the Premises,

54   and otherwise in Landlord's reasonable discretion,

55   unless, upon Tenant's written request therefor made at the time Tenant
     requests Landlord's consent to the Alterations, Landlord has specified
     otherwise in writing

                                      19
<PAGE>

mechanics' and materialmen's liens, and Tenant shall give to Landlord written 
notice of the commencement of any construction in or on the Premises at least 
thirty (30) business days prior thereto.  Prior to the commencement of any 
such construction, Landlord shall be furnished certificates of insurance, 
naming Landlord as an additional insured, evidencing that each contractor 
performing work has insurance acceptable to Landlord, including but not 
limited to general liability insurance of not less that Two Million Dollars 
($2,000,000.00) and worker's compensation insurance in the statutorily 
required amount.


SECTION XIII.  MECHANIC'S LIENS

Tenant shall keep the Premises, the Building and the Project free from any 
liens arising out of any work performed, material furnished or obligation 
incurred by or for Tenant or any person or entity claiming through or under 
Tenant.  In the event that Tenant shall not, within (56)ten (10) days following
the imposition of any such lien, cause the same to be released of record by 
payment or posting of a proper bond, Landlord shall have, in addition to all 
other remedies provided herein and by law, the right, but not the obligation, 
to cause such lien to be released by such means as Landlord deems proper, 
including payment of the claim giving rise to such lien.  All such sums paid 
and all expenses incurred by Landlord in connection therewith shall be due 
and payable to Landlord by Tenant on demand.


SECTION XIV.  INSURANCE

A.   TENANT

     During the Term hereof, Tenant shall keep in full force and effect the 
     following insurance and shall provide appropriate insurance certificates 
     to Landlord prior to the Lease Commencement Date and annually thereafter 
     before the expiration of each policy:

     (1)  Commercial general liability insurance for the benefit of Tenant 
          and Landlord as an additional insured, with a limit of not less 
          than One Million Dollars ($1,000,000.00) combined single limit per 
          occurrence, against claims for personal injury liability including, 
          without limitation, bodily injury, death or property damage 
          liability and covering (i) the business(es) operated by Tenant and 
          by any subtenant of Tenant on the Premises, (ii) operations of 
          independent contractors engaged by Tenant for services or 
          construction on or about the Premises, and (iii) contractual 
          liability;

     (2)  Fire, extended coverage, vandalism and malicious mischief 
          insurance, insuring the personal property, furniture, furnishings 
          and fixtures belonging to Tenant located on the Premises for not 
          less than one hundred percent (100%) of the actual replacement 
          value thereof;

     (3)  Workers' compensation in the amount required by law;

     (4)  Business interruption or loss of income insurance in amounts 
          satisfactory to Landlord, with a rental interruption rider assuring 
          Landlord that the rent due hereunder will be paid for a period of 
          not less than twelve (12) months if the Premises are destroyed or 
          rendered inaccessible by a risk insured against by a policy of all 
          risk insurance; and

     (5)  Such other insurance(57) as Landlord deems reasonably necessary(58).

<PAGE>

     Each insurance policy obtained by Tenant pursuant to this Lease shall 
     contain a clause that the insurer will provide Landlord with at least 
     thirty (30) days' prior written notice of any material change, non-renewal
     or cancellation of the policy, shall be in a form satisfactory to Landlord 
     and shall be taken out with an insurance company authorized to do business 
     in the State in which the Project is located and rated not less than Best's
     Financial Class X and Best's Policy Holder Rating "A".  In addition, any 
     insurance policy obtained by Tenant shall be written as a primary policy, 
     and shall not be contributing with or in excess of any coverage which 
     Landlord may carry, and shall have loss payable clauses satisfactory to 
     Landlord and in favor of Landlord naming Landlord, and any other party 
     reasonably designated by Landlord, as an additional insured.  The liability
     limits of the above described insurance policies shall in no matter limit 
     the liability of Tenant under the terms of Section XV. below.

     Not more frequently than every two (2) years, if, in the reasonable 
     opinion of Landlord, the amount of liability insurance specified in this 
     Section XIV. is not adequate, the above-described limits of coverage 
     shall be adjusted by Landlord, by written notification to Tenant, in 
     order to maintain the level of insurance protection at least equal to 
     the protection afforded on the date the Term commences(59).  If Tenant 
     fails to maintain and secure the insurance coverage required under this 
     Section XIV., then Landlord shall have, in addition to all other 
     remedies provided herein and by law, the right, but not the obligation, 
     to procure and maintain such insurance, the cost of which shall be due 
     and payable to Landlord by Tenant on demand.

     If, on account of the failure of Tenant to comply with the provisions of 
     this Section, Landlord is deemed a co-insurer by its insurance carrier, 
     then any loss or damage which Landlord shall sustain by reason thereof 
     shall be borne by Tenant and shall be immediately paid by Tenant as 
     additional rent upon receipt of a bill therefor and evidence of such loss.

B.   LANDLORD

     During the Term hereof, Landlord shall keep in full force and effect the 
     following insurance:

     (1)  Fire, extended coverage and vandalism and malicious mischief 
          insurance insuring the Building and Project of which the Premises 
          are a part, in an amount not less than eighty percent (80%)(or such 
          greater percentage as may be required by law) of the full 
          replacement cost thereof; and

     (2)  Such other insurance as Landlord deems necessary in its sole and 
          absolute discretion(60).

     All insurance policies shall be issued in the names of Landlord and 
     Landlord's lender, and any other party reasonably designated by Landlord 
     as an additional insured, as their interests appear.  The insurance 
     policies shall provide that any proceeds shall be made payable to 
     Landlord, or to the holders of mortgages or deeds of trust encumbering

(60) , provided that Landlord adjusts the Base Operating Expense 
     appropriately in the event Landlord carries additional insurance of a 
     type not included in determining the Base Operating Expense which is not 
     a replacement for insurance costs included in the Base Operating Expense.

     insurance shall be included in Common Operating Costs.

     (61)

C.   WAIVER OF SUBROGATION

     Landlord and Tenant each hereby waives any and all rights of recovery 
     against the other, and against any other tenant or occupant of the 
     Project and against the officers, employees, agents, representatives, 
     customers and business visitors of such other party and of each such 
     other tenant or occupant of the Project, for loss of or damage to such 
     waiving party or its property or the property of others under its 
     control, arising from any cause insured against under any policy of 
     property insurance required to be carried by such waiving party pursuant 
     to the provisions of this Lease (or any other policy of property 
     insurance carried by such waiving party in lieu thereof) at the time of 
     such loss or damage.  The foregoing waiver shall be effective whether or 
     not a waiving party actually obtains and maintains such insurance which 
     such waiving party is required to obtain and maintain pursuant to this 
     Lease (or any substitute therefor).  Landlord and Tenant shall, upon 
     obtaining the policies of insurance which they are required to maintain 
     hereunder, give notice to their respective insurance carrier or carriers 
     that the foregoing mutual waiver of subrogation is contained in this Lease.


SECTION XV.  INDEMNITY

A.   TENANT

     Tenant agrees to indemnify, defend and hold Landlord and its officers, 
     directors, partners and employees entirely harmless from and against all 
     liabilities, losses, demands, actions, expenses or claims, including 
     reasonable attorneys' fees and court costs(62), for injury to or death of 
     any person or for damages to any property or for violation of law arising 
     out of or in any manner connected with (i) the use, occupancy or enjoyment 
     of the Premises, Building or Project by Tenant or Tenant's agents, 
     employees, invitees or contractors (the "Tenant's Agents") or any work, 
     activity or other things allowed or suffered by Tenant or Tenant's Agents 
     to be done in or about the Premises, Building or Project, (ii) any breach 
     or default in the performance of any obligation of Tenant under this Lease,
     and (iii) any act or failure to act, whether negligent or otherwise 
     tortious, by Tenant or Tenant's Agents in or about the Premises, Building 
     or Project.(63)

B.   LIMITATION ON LANDLORD'S LIABILITY; RELEASE OF DIRECTORS, OFFICERS AND 
     PARTNERS OF LANDLORD

     Tenant agrees that, in the event Tenant shall have any claim against 
     Landlord under this Lease arising out of the subject matter of this 
     Lease, Tenant's sole recourse shall be


________________________

(61) If, on account of the failure of Landlord to comply with the provisions 
     of this Section, Tenant is deemed a co-insurer by its insurance 
     carrier, then any loss or damage which Tenant shall sustain by reason 
     thereof shall be borne by Landlord and shall be immediately paid by 
     Landlord upon receipt of a bill therefor and evidence of such loss.

(62) (herein "Claims")

(63) Notwithstanding the foregoing, if and to the extent that a court of 
     competent jurisdiction determines that a Claim was caused by the gross 
     negligence or willful misconduct of Landlord, then Landlord shall be 
     required to reimburse to Tenant the reasonable attorneys' fees incurred 
     by Tenant in defending Landlord in connection with such Claim.

                                       22

<PAGE>

     against the Landlord's interest in the Building, for the satisfaction of 
     any claim, judgment or decree requiring the payment of money by Landlord 
     as a result of a breach hereof or otherwise in connection with this 
     Lease, and no other property or assets of Landlord, its successors or 
     assigns, shall be subject to the levy, execution or other enforcement 
     procedure for the satisfaction of any such claim, judgment, injunction 
     or decree.  Moreover, Tenant agrees that Landlord shall in no event and 
     under no circumstances be responsible for any consequential damages 
     incurred or sustained by Tenant, or its employees, agents, contractors 
     or invitees as a result of or in any way connected to Tenant's occupancy 
     of the Premises.  Tenant further hereby waives any and all right to 
     assert any claim against or obtain any damages from, for any reason 
     whatsoever, the directors, officers and partners of Landlord, including 
     all injuries, damages or losses to Tenant's property, real and personal, 
     whether known, unknown, foreseen, unforeseen, patent or latent, which 
     Tenant may have against Landlord or its directors, officers or partners. 
     Tenant understands and acknowledges the significance and consequence of 
     such specific waiver.

     Landlord shall not be liable or responsible to Tenant for any loss or 
     damage to any property or person occasioned by theft, fire, act of God, 
     public enemy, injunction, riot, strike, insurrection, war, court order, 
     requisition, or order of governmental body or authority, or for any 
     damage or inconvenience that may arise through repair or alteration of 
     any part of the Project, the Building or the Premises, or a failure to 
     make any such repairs, except as expressly provided in this Lease.


SECTION XVI.  ASSIGNMENT AND SUBLETTING BY TENANT

A.   Tenant shall not, directly or indirectly, voluntarily or by operation of 
     law, sell, assign, encumber, pledge or otherwise transfer or hypothecate 
     all or any part of the Premises or Tenant's leasehold estate hereunder 
     (collectively "Assignment"), or permit the Premises to be occupied by 
     anyone other than Tenant or sublet the Premises ("Sublease") or any 
     portion thereof without Landlord's prior written consent being had and 
     obtained in each instance, subject to the terms and conditions contained 
     in the Section(64).

B.   If Tenant desires at any time to enter into an Assignment of this Lease 
     or a Sublease of the Premises or any portion thereof(65), Tenant shall 
     request, in writing, at least sixty (60) days prior to the effective 
     date of the Assignment or Sublease, Landlord's consent to the Assignment 
     or Sublease, and shall provide Landlord with the following information:

     (1)  The name of the proposed assignee, subtenant or occupant;

     (2)  The nature of the proposed assignee's, subtenant's or occupant's 
          business to be carried on in the Premises;


________________________

(64) Notwithstanding the foregoing, Landlord's consent to an Assignment or 
     Sublease to Tenant's parent or to a wholly-owned subsidiary of Tenant or 
     its parent (herein, "Affiliate") shall not be required so long as there 
     is no change in use of the Premises.  Moreover, Landlord's prior consent 
     shall not be required in connection with an Assignment of the Lease in 
     connection with (1) a sale of all or substantially all of Tenant's 
     assets to a single purchaser in a single transaction, (2) a merger or 
     consolidation of Tenant with or into another entity or (3) in connection 
     with a public offering of Tenant's stock on a nationally recognized 
     public exchange, so long as, in connection therewith, (a) there shall be 
     no change in use of the Premises and (b) the net worth and proforma 
     revenues of the assignee immediately after such transfer are equal to or 
     greater than that of Tenant immediately prior to such transfer.

<PAGE>

    (3)  The terms and provisions of the proposed Assignment or Sublease and a
         copy of such documents; and

    (4)  Such financial information concerning the proposed assignee, 
         subtenant or occupant which Landlord shall have requested following 
         its receipt of Tenant's request for consent.

     (66)

C.  At any time within thirty (30) days after Landlord's receipt of the 
    notice specified above, Landlord may by written notice to Tenant elect
    either to (a) consent to the proposed Assignment or Sublease(67), (b) refuse
    to consent to the proposed Assignment or Sublease, or (c) terminate this 
    Lease in full with respect to an Assignment or terminate in part with 
    respect to a Sublease and enter into a lease directly with the proposed
    assignee or sublessee. Landlord and Tenant agree (by way of example and
    without limitation) that Landlord shall be entitled to take into account 
    any fact or factor which Landlord reasonably deems relevant to such 
    decision, including but not necessarily limited to the following, all of
    which are agreed to be reasonable factors for Landlord's consideration:

    (1)  The financial strength of the proposed assignee or subtenant 
         (which shall be at least equal to that of Tenant as of the date of 
         execution of this Lease), including the adequacy of its working 
         capital to pay all expenses anticipated in connection with any 
         remodeling of the Premises.

    (2)  The experience of the proposed assignee or subtenant with respect to 
         businesses of the type and size which such assignee or subtenant 
         proposes to conduct in the Premises.

    (3)  The quality and nature of the business and/or services to be 
         conducted in or from the Premises by the proposed assignee or 
         subtenant and in any other locations which it has, as reflected by,
         among other things, average sales or revenue.

    (4)  Violation of exclusive use rights previously granted by Landlord to 
         other tenants of the Building or Project.

    (5)  The effect of the type of services and business which the proposed 
         assignee or subtenant proposes to conduct in the Premises upon the 
         tenant mix in the Building or in the portion of the Project which 
         contains the Premises, including duplication of services offered by
         surrounding tenants and compatibility of the services and business 
         which such assignee or subtenant proposes to conduct in or offer from
         the Premises with business and services conducted by surrounding 
         tenants in the Project.

    (6)  Diminution or potential diminution of percentage rent, if any, 
         payable pursuant to this Lease as the result of such Assignment or 
         Sublease.

    (7)  The quality of the appearance of the Premises resulting from any 
         remodeling or renovation to be conducted by the proposed assignee or 
         subtenant, and the compatibility of such quality with that of other
         premises in the Building.


- ------------------
  (66) Tenant shall also provide to Landlord the foregoing information at the 
       time Tenant notifies Landlord of any Assignment or Sublease for which 
       Landlord's consent is not required hereunder.

  (67) or


                                     24

<PAGE>

    (8)  Whether the business in the Premises is, and whether the business to 
         be operated by the proposed assignee or subtenant will be, a "(68)
         destination business" (i.e., a business which draws patrons to the 
         Project or the Building specifically to obtain services from such 
         business).

    (9)  Whether there then exists any default by Tenant pursuant to this 
         Lease or any non-payment or non-performance by Tenant under this 
         Lease which, with the passage of time and/or the giving of notice,
         would constitute a default under this Lease.

    (10) Any fact or factor upon which Landlord reasonably concludes that the
         business to be conducted by such assignee or subtenant will not be a
         financial success in the Premises.

    Moreover, Landlord shall be entitled to be reasonably satisfied that each 
    and every covenant, condition or obligation imposed upon Tenant by this 
    Lease and each and every right, remedy or benefit afforded Landlord by 
    this Lease is not impaired or diminished by such Assignment or Sublease.
    In no event shall there be any substantial change in the use of the Premises
    in connection with any Assignment or Sublease except as expressly approved
    in writing by Landlord in advance. Landlord and Tenant acknowledge that 
    the express standards and provisions set forth in this Lease dealing with 
    Assignment and Sublease, including those set forth in subsections XVI.D., 
    E. and G. have been freely negotiated and are reasonable at the date 
    hereof taking into account Tenant's proposed use of the Premises and the
    nature and quality of the Building and Project. No withholding of consent
    by Landlord for any reason deemed sufficient by Landlord shall give rise
    to any claim by Tenant or any proposed assignee or subtenant or entitle
    Tenant to terminate this Lease or to any abatement of rent. Approval of 
    any Assignment of Tenant's interest shall, whether or not expressly so 
    stated, be conditioned upon such assignee assuming in writing all 
    obligations of Tenant hereunder by a written instrument satisfactory to
    Landlord.

D.  If Landlord consents to the Sublease or Assignment within said thirty (30)
    day period, Tenant may enter into such Assignment or Sublease of the 
    Premises or portion thereof, but only upon the terms and conditions set
    forth in the notice furnished by Tenant to Landlord pursuant to 
    subsection B. above; provided, however, that in connection with(69) such
    Assignment or Sublease(70), as a condition to Landlord's consent, Tenant
    shall pay to Landlord one hundred percent (100%) of the excess, if any, 
    of (i) in the case of an Assignment, the rental and other payment 
    obligations of the proposed assignee under the terms of the proposed
    Assignment over (71)the rental and other payment obligations of Tenant 
    under the terms of this Lease(72), or (ii) in the case of a Sublease, the

E.  No consent by Landlord to any Assignment or Sublease by Tenant shall 
    relieve Tenant of any obligation to be performed by Tenant under this 
    Lease, whether arising before or after the Assignment or Sublease. The
    consent by Landlord to any Assignment or Sublease shall not relieve 
    Tenant of the obligation to obtain Landlord's express written consent to
    any other Assignment or Sublease. Any Assignment or Sublease that is not
    in compliance with this Section shall be void and, at the option of 
    Landlord, shall constitute a material default by Tenant under this Lease.
    The acceptance of rent by Landlord or payment to Landlord of any other
    monetary obligation by a proposed assignee or sublessee shall not 
    constitute the consent by Landlord to such Assignment or Sublease. Tenant
    shall promptly provide to Landlord a copy of the fully executed Sublease
    or Assignment.

F.  Any sale or other transfer, including transfer by consolidation, merger or
    reorganization, of twenty-five percent (25%) or more of the voting stock of
    Tenant, if Tenant is a corporation, or any sale or other transfer of 
    twenty-five percent (25%) or more of the partnership interest in Tenant, 
    if Tenant is a partnership, shall be an Assignment for purposes of this 
    Section. As used in this subsection, the term "Tenant" shall also mean any
    entity that has guaranteed Tenant's obligation under this Lease, and the 
    prohibition hereof shall be applicable to any sales or transfers of stock
    or partnership interests of said guarantor.

G.  Each assignee, sublessee or other transferee, other than Landlord, shall
    assume, as provided in this subsection all obligations of Tenant under 
    this Lease and shall be and remain liable jointly and severally with 
    Tenant for the payment of Monthly Rental and all other monetary 
    obligations hereunder, and for the performance of all the terms, 
    covenants, conditions and agreements herein contained on Tenant's part to
    be performed for the Term; provided, however, that the assignee, 
    sublessee, or other transferee shall be liable to Landlord for rent only
    in the amount set forth in the Assignment or Sublease. No Assignment shall
    be binding on Landlord unless the assignee or Tenant shall deliver to 
    Landlord a counterpart of the Assignment and an instrument in recordable 
    form that contains a covenant of assumption by the assignee satisfactory in
    substance and form to Landlord, consistent with the requirements of this
    subsection but the failure or refusal of the assignee to execute such
    instrument of assumption shall not release or discharge the assignee from
    its liability as set forth above.

H.  If this Lease is assigned to any person or entity pursuant to the 
    provisions of the Bankruptcy Code, 11 U.S.C. Section 101 ET SEQ., (the 
    "Bankruptcy Code"), any and all monies or other consideration payable or 
    otherwise to be delivered in connection with such assignment shall be paid
    or delivered to Landlord, shall be and remain the exclusive property of 
    Landlord and shall not constitute property of Tenant or of the estate of
    Tenant within the meaning of the Bankruptcy Code. Any and all monies or
    other considerations constituting Landlord's property under the preceding
    sentence not paid or delivered to Landlord shall be held in trust for the
    benefit of Landlord and be promptly paid or delivered to Landlord.

I.  Any person or entity to which this Lease is assigned pursuant to the 
    provisions of the Bankruptcy Code, shall be deemed, without further act
    or deed, to have assumed all of the obligations arising under this Lease
    on and after the date of such assignment. Any

  (74) plus (2) the unamortized costs of improvements incurred and paid for by
       Tenant (I.E., not covered by the Tenant Allowance) which are included 
       in Tenant's Work and which are usable and used by the subtenant and 
       brokers' commissions, advertising costs and costs of tenant 
       improvements required to be paid or performed by Tenant as a condition 
       to or in connection with such Sublease, spread evenly over the term of
       the Sublease and deducted from the sublessee's rentals so amortized, 
       in each case

<PAGE>

    such assignee shall upon demand execute and deliver to Landlord an 
    instrument confirming such assumption.

J.  Tenant shall pay Landlord's expenses and (75)attorneys' fees incurred in
    processing an Assignment or Sublease, but in no event less than Five 
    Hundred Dollars ($500.00) for each such proposed transfer to cover the
    legal review and processing expenses of Landlord, whether or not Landlord
    shall grant its consent to such proposed transfers.

K.  All options to extend, renew or expand, if any, contained in this Lease 
    are personal to Tenant(76). Consent by Landlord to any Assignment or
    Subletting shall not include consent to the assignment or transfer of any
    such rights with respect to the Premises or any special privileges or 
    extra services granted to Tenant by this Lease, or any addendum or 
    amendment hereto or letter of agreement. All such options, rights,
    privileges and extra services shall terminate upon such assignment or
    subletting unless Landlord specifically grants in writing such options,
    rights, privileges and extra services to such assignee or subtenant. 
    Similarly, any allowance, abatement or monetary concession provided to
    Tenant as an inducement to execute this Lease is personal to Tenant and 
    shall be amortized (on a straight line basis) over the term of this Lease.
    Upon any assignment or subletting, the then unamortized portion thereof
    shall be paid by Tenant to Landlord in cash on or before the effective 
    date of such assignment or subletting.


SECTION XVII. TRANSFER OF LANDLORD'S INTEREST

In the event Landlord shall sell or otherwise convey its title to the Building,
then, after the effective date of such sale or conveyance, Landlord shall have
no further liability under this Lease to Tenant except as to matters of 
liability which have accrued and are unsatisfied as of the date of sale or 
conveyance, and Tenant shall seek performance solely from Landlord's 
purchaser or successor in title. In connection with such sale or transfer, 
Landlord may assign its interest under this Lease without notice to or 
consent by Tenant. In such event, Tenant agrees to be bound to any successor 
Landlord.


SECTION XVIII. DAMAGE AND DESTRUCTION

A.  MINOR INSURED DAMAGE

    In the event the Premises or the Building, or any portion thereof, is 
    damaged or destroyed by any casualty that is covered by the insurance
    maintained by Landlord pursuant to Section XIV. above, then Landlord shall
    rebuild, repair and restore the damaged portion thereof, provided that 
    (1) the amount of insurance proceeds available to Landlord equals or 
    exceeds the cost of such rebuilding, restoration and repair, (2) such
    rebuilding, restoration and repair can be completed within one hundred
    eighty (180) days after the work commences in the (77)opinion of a 
    registered architect or engineer appointed by Landlord, (3) the damage or 
    destruction has occurred more than twelve (12) months before the 
    expiration of the Term, and (4) such rebuilding, restoration or repair is
    then permitted, under applicable governmental laws, rules and regulations,
    to be done in such a manner as to return the damaged portion thereof to 
    substantially its condition immediately prior to the damage or 
    destruction, including, without limitation, the same net rentable floor 
    area. To the extent that insurance proceeds must be paid to a mortgagee 
    or beneficiary under, or must be applied to reduce any indebtedness

      by, a mortgage or deed of trust encumbering the Premises, Building or 
      Project, such proceeds, for the purposes of this subsection, shall be 
      deemed not available to Landlord unless such mortgagee or beneficiary  
      permits Landlord to use such proceeds for the rebuilding, restoration and
      repair of the damaged portion thereof. Notwithstanding the foregoing, 
      Landlord shall have no obligation to repair any damage to, or to replace
      any of, Tenant's personal property, furnishings, trade fixtures, 
      equipment or other such property or effects of Tenant.

B.    MAJOR OR UNINSURED DAMAGE

      In the event the Premises or the Building, or any portion thereof, is 
      damaged or destroyed by any casualty to the extent that Landlord is not 
      obligated, under subsection A. above, to rebuild, repair or restore the 
      damaged portion thereof, then Landlord shall, within sixty (60) days 
      after such damage or destruction, notify Tenant of its election, at its 
      option, to either (1) rebuild, restore and repair the damaged portions 
      thereof, in which case Landlord's notice shall specify the time period 
      within which Landlord estimates such repairs or restoration can be 
      completed; or (2) terminate this Lease effective as of the date the  
      damage or destruction occurred. If Landlord does not give Tenant written  
      notice within (60) days after the damage or destruction occurs of
      its election to rebuild or restore and repair the damaged portions 
      thereof, Landlord shall be deemed to have elected to terminate this
      Lease.(78)

C.    ABATEMENT OF RENT

      There shall be an abatement of rent by reason of damage to or 
      destruction of the Premises or the Building, or any portion thereof,
      to the extent that Landlord receives insurance proceeds for loss of 
      rental income attributable to the Premises, commencing on the date that 
      the damage to or destruction of the Premises or Building has occurred.

D.     WAIVER

       Tenant shall have no claim against Landlord for any damage suffered by 
       Tenant by reason of any such damage, destruction, repair or 
       restoration. Tenant waives the provisions of Civil Code Sections 
       1932(2) and 1933(4) and any present or future laws or case decisions 
       to the same effect. Upon completion of such repair or restoration, 
       Tenant shall promptly refixture the Premises substantially to the 
       condition they were in prior to the casualty and shall reopen for 
       business if closed by the casualty.


SECTION XIX. CONDEMNATION

A.     TOTAL OR PARTIAL TAKING

       If all or substantially all of the Premises is condemned or taken in 
       any manner for public or quasi-public use, including but not limited 
       to, a conveyance or assignment in lieu of

 .........................

    (78)Notwithstanding the foregoing, upon the occurrence of major damage 
        after Tenant has paid Monthly Rental for at least twenty-four (24) 
        months of the Term, for which the estimated repair time is 
        determined to exceed on hundred eighty (180) days, Tenant shall have 
        the right to terminate the Lease provided Tenant is not then in 
        default hereunder and the damage or destruction was not caused 
        by Tenant or anyone for whom Tenant is responsible, and 
        provided further that Tenant notifies Landlord of its election to 
        terminate the Lease in writing within ten (10) days after the damage 
        or destruction occurs. If Tenant is entitled to and properly 
        exercises the foregoing option strictly in the manner and within the 
        time set forth herein, and if Landlord's notice given pursuant to the 
        first sentence of this subsection B. specifies an estimated repair 
        time in excess of one hundred eighty (180) days, then the Lease shall 
        terminate effective as of the later of the date of Tenant's election 
        notice or the date Tenant vacated the Premises.

                                       28

<PAGE>

       the condemnation or taking, this Lease shall automatically terminate as 
       of the earlier of the date on which actual physical possession is 
       taken by the condemnor or the date of dispossession of Tenant as a 
       result of such condemnation or other taking. If less than all or 
       substantially all of the Premises is so condemned or taken, this Lease 
       shall automatically terminate only as to the portion of the Premises so 
       taken as of the earlier of the date on which actual physical possession 
       is taken by the condemnor or the date of dispossession of Tenant as a 
       result of such condemnation or taking (79). If such portion of the 
       Building is condemned or otherwise taken so as to require, in the 
       opinion of Landlord, a substantial alteration or reconstruction of the 
       remaining portions thereof, this Lease may be terminated by Landlord, 
       as or the date on which actual physical possession is taken by the 
       condemnor of dispossession of Tenant as a result of such condemnation 
       or taking, by written notice to Tenant within sixty (60) days following 
       notice to Landlord of the date on which such physical possession is 
       taken or dispossession will occur.

B.     AWARD

       Landlord shall be entitled to the entire award in any condemnation 
       proceeding or other proceeding for taking for public or quasi-public 
       use, including, without limitation, any award made for the value of the 
       leasehold estate created by this Lease. No award for any partial or 
       total taking shall be apportioned, and Tenant hereby assigns to 
       Landlord any award that may be made in such condemnation or other 
       taking, together with any and all rights of Tenant now or hereafter 
       arising in or to the same or any part thereof. Although all damages in 
       the event of any condemnation are to belong to Landlord whether such 
       damages are awarded as compensation for diminution in value of the 
       leasehold or to the fee of the Premises, Tenant shall have the right to 
       claim and recover from the condemnor, but not from Landlord, such 
       compensation as may be separately awarded or recoverable by Tenant in 
       Tenant's own right on account of damages to Tenant's business by reason 
       of the condemnation and for or on account of any cost or loss to which 
       Tenant might be put in removing Tenant's merchandise, furniture and 
       other personal property, fixtures, and equipment or for the 
       interruption of or damage to Tenant's business.

C.     ABATEMENT IN RENT

       In the event of a partial condemnation or other taking that does not 
       result in a termination of this Lease as to the entire Premises 
       pursuant to this Section the rent and all other charges shall abate in 
       proportion to the portion of the Premises taken by such condemnation 
       or other taking. If this Lease is terminated, in whole or in part, 
       pursuant to any of the provisions of this Section all rentals and other 
       charges payable by Tenant to Landlord hereunder and attributable to the 
       Premises taken shall be paid up to the date upon which actual physical 
       possession shall be taken by the condemnor. Landlord shall be entitled 
       to retain all of the Security Deposit until such time as this Lease is 
       terminated as to all of the Premises.

D.     TEMPORARY TAKING

       If all or any portion of the Premises is condemned or otherwise taken 
       for public or quasi-public use for a limited period of time(80), this 
       Lease shall remain in full force and effect and Tenant shall continue 
       to perform all terms, conditions and covenants of this Lease; provided, 
       however, the rent and all other charges payable by Tenant to Landlord 

 .........................

    (79); provided, however, if more than ten percent (10%) of the Premises 
        is taken in condemnation, then unless Landlord makes available 
        additional replacement space in the Building, Tenant shall have the 
        right to terminate the Lease, effective as of the date such portion of 
        the Premises is taken.

    (80)(not to exceed six (6) consecutive months, if the taking materially 
        impairs Tenant's ability to use the Premises)

<PAGE>

       hereunder shall abate during such limited period in proportion to the 
       portion of the Premises that is rendered untenantable and unusable as a 
       result of such condemnation or other taking.(81) Landlord shall be 
       entitled to receive the entire award made in connection with any such 
       temporary condemnation or other taking. Tenant shall have the right to 
       claim and recover from the condemnor, but not from Landlord, such 
       compensation as may be separately awarded or recoverable by Tenant in 
       Tenant's own right on account of damages to Tenant's business by reason 
       of the condemnation and for or on account of any cost or loss to which 
       Tenant might be put in removing Tenant's merchandise, furniture and 
       other personal property, fixtures and equipment or for the interruption 
       of or damage to Tenant's business.

E.     TRANSFER OF LANDLORD'S INTEREST TO CONDEMNOR

       Landlord may, without any obligation to Tenant, agree to sell and/or 
       convey to the condemnor the Premises, the Building, the Project or any 
       portion thereof, sought by the condemnor, free from this Lease and the 
       rights of Tenant hereunder, without first requiring that any action or 
       proceeding be instituted or, if instituted, pursued to a judgment.


SECTION XX. DEFAULT

             Premises;

      (2)    If Tenant fails to pay any rent or other charge required 
             to be paid by Tenant under this Lease and such

             payment is due and payable(83); provided, however, 
             that the obligation of Tenant to pay a late charge 
             or interest pursuant to this Lease below shall 
             commence as of the due date of the rent or such 
             other monetary obligation and not on the expiration 
             of such five (5) (84)day grace period;

      (3)    If Tenant involuntarily transfers Tenant's interest in

             interest in this Lease, without Landlord's prior written 
             consent(85);

      (4)    If Tenant files a voluntary petition for relief or if a

       recover rent and any other additional monetary charges as they become 
       due, for as long as Landlord does not terminate Tenant's right to 
       possession. Acts of maintenance or preservation, efforts to relet the 
       Premises, the appointment of a receiver upon Landlord's initiative to 
       protect its interest under this Lease or Landlord's withholding of 
       consent to an Assignment or Subletting pursuant to the terms and 
       conditions of Section XVI. above shall not constitute a termination of 
       Tenant's right to possession.

   (3) The foregoing provisions of clause (2) shall apply even though Tenant 
       has breached the Lease and abandoned the Premises, in which case Landlord
       shall have the right to re-enter the Premises with or without process of 
       law to eject therefrom all parties in possession thereof, and, without 
       terminating this Lease, at any time and from time to time, but without 
       obligation to do so, to relet the Premises and the improvements located 
       therein or any part or parts of any thereof for the account of Tenant, or
       otherwise, on such conditions as Landlord in its discretion may deem 
       proper, with the right to make alterations and repairs to the Premises in
       connection therewith, and to receive and collect the rents therefor, and 
       apply the same (i) first to the payment of such costs and expenses as 
       Landlord may have paid, assumed or incurred: (A) in recovering possession
       of the Premises and said improvements, including attorneys' fees, and 
       costs; (B) expenses for placing the Premises and said improvements in 
       good order and condition, for decorating and preparing the Premises for 
       reletting; (C) for making 

- -------------
(93) reasonable

                                       32

<PAGE>

       any alterations, repairs, changes or additions to the Premises that may 
       be necessary or convenient; and (D) all other costs and expenses, 
       including leasing and subleasing commissions, and charges paid, assumed 
       or incurred by Landlord in or upon reletting the Premises and said 
       improvements, or in fulfillment of the covenants of Tenant under this 
       Lease; (ii) then to the payment of Monthly Rental, Tenant's Proportionate
       Share of Common Operating Costs, and other monetary obligations due and 
       unpaid hereunder; and (iii) any balance shall be held by Landlord and 
       applied in payment of future amounts as the same may become due and 
       payable hereunder. Any such reletting may be for the remainder of the 
       term of this Lease or for a longer or shorter period. Landlord may 
       execute any lease or sublease made pursuant to the terms of this clause 
       (3) either in its own name or in the name of Tenant as its agent, as 
       Landlord may see fit. The tenant(s) or subtenant(s) thereunder shall be 
       under no obligation whatsoever with regard to the application by Landlord
       of any rent collected by Landlord from such tenant or subtenant to any 
       and all sums due and owing or which may become due and owing under the 
       provisions of this Lease, nor shall Tenant have any right or authority 
       whatever to collect any rent whatever from such tenant(s) or 
       subtenant(s). If Tenant has been credited with any rent received by such 
       reletting and such rent shall not be promptly paid to Landlord by the 
       tenant(s) or subtenant(s), or if such rentals received from reletting 
       during any month are less than those to be paid during that month by 
       Tenant hereunder, Tenant shall pay any such deficiency to Landlord. Such 
       deficiency shall be calculated and paid monthly. Tenant shall also pay to
       Landlord as soon as ascertained, any costs and expenses incurred by 
       Landlord in such reletting or in making such alterations and repairs not 
       covered by the rentals received from such reletting. For all purposes set
       forth in this subsection, Landlord is hereby irrevocably appointed as 
       agent for Tenant. No taking of possession of the Premises by Landlord 
       shall be construed as Landlord's acceptance of a surrender of the 
       Premises by Tenant or an election of Landlord's part to terminate this 
       Lease unless written notice of such intention is given to Tenant. 
       Notwithstanding any such subletting without termination, Landlord may 
       at any time thereafter elect to terminate this Lease for such previous 
       breach. Election by Landlord to proceed pursuant to this clause (3) shall
       be made upon written notice to Tenant and shall be deemed an election of 
       the remedy described in California Civil Code Section 1951.4 (providing 
       that a lessor of real property may continue a lease in effect after a 
       lessee's breach or abandonment and recover rent as it becomes due, if the
       lessee has the right to sublet or assign, subject only to reasonable 
       limitations). If Landlord elects to pursue such remedy, unless Landlord 
       relets the Premises, Tenant shall have the right to sublet the Premises 
       and to assign its interest in this Lease, subject to all of the standards
       and conditions set forth in Section XVI. Landlord may elect to terminate 
       the prosecution of such remedy at any time by written notice to Tenant, 
       and the right of Tenant to sublet or assign shall terminate upon receipt 
       by Tenant of such notice.

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

SECTION XXI. LATE PAYMENTS/INTEREST AND LATE CHARGES

A. INTEREST

   Any amount due from Tenant to Landlord which is not paid when due shall 
   bear interest at the maximum rate permitted by law from the date such payment
   is due until paid, except that amounts spent by Landlord on behalf of Tenant 
   shall bear interest at such rate from the date of disbursement by Landlord 
   which Tenant agrees is to compensate

                                       33

<PAGE>

   Landlord for Tenant's use of Landlord's money after it is due. Payment of 
   such interest shall not excuse or cure any default by Tenant pursuant to this
   Lease. Such rate shall remain in effect after the occurrence of any breach or
   default hereunder by Tenant to and until payment of the entire account due.

B. LATE CHARGES

   TENANT HEREBY ACKNOWLEDGES THAT IN ADDITION TO LOST INTEREST, THE LATE 
   PAYMENT BY TENANT TO LANDLORD OF RENT OR ANY OTHER SUMS DUE HEREUNDER WILL 
   CAUSE LANDLORD TO INCUR OTHER COSTS NOT CONTEMPLATED IN THIS LEASE. THE EXACT
   AMOUNT OF WHICH WILL BE EXTREMELY DIFFICULT AND IMPRACTICABLE TO ASCERTAIN. 
   SUCH OTHER COSTS INCLUDE, BUT ARE NOT LIMITED TO, PROCESSING, ADMINISTRATIVE 
   AND ACCOUNTING COSTS, AND LATE CHARGES WHICH MAY BE IMPOSED UPON LANDLORD BY 
   THE TERMS OF ANY ENCUMBRANCE COVERING THE PREMISES. ACCORDINGLY, IF ANY 
   INSTALLMENT OF RENT OR ANY ADDITIONAL RENT OR OTHER SUM DUE FROM TENANT 
   SHALL NOT BE RECEIVED BY LANDLORD WHEN SUCH AMOUNT SHALL BE DUE (WITHOUT 
   REGARD TO ANY GRACE PERIOD GRANTED IN THIS LEASE), TENANT SHALL PAY TO 
   LANDLORD AS ADDITIONAL RENT HEREUNDER A LATE CHARGE EQUAL TO TEN(94) PERCENT 
   (10(95)%) OF SUCH OVERDUE AMOUNT. THE PARTIES HEREBY AGREE THAT (I) SUCH LATE
   CHARGE REPRESENTS A FAIR AND REASONABLE ESTIMATE OF THE COSTS LANDLORD WILL 
   INCUR IN PROCESSING SUCH DELINQUENT PAYMENT BY TENANT, (II) SUCH LATE CHARGE
   SHALL BE PAID TO LANDLORD AS LIQUIDATED DAMAGES FOR EACH DELINQUENT PAYMENT,
   AND (III) THE PAYMENT OF THE LATE CHARGE IS TO COMPENSATE LANDLORD FOR THE 
   ADDITIONAL ADMINISTRATIVE EXPENSE INCURRED BY LANDLORD IN HANDLING AND 
   PROCESSING DELINQUENT PAYMENTS.

C. CONSECUTIVE LATE PAYMENT OF RENT

   Following each (96)second consecutive late payment of rent, Landlord shall 
   have the option (i) to require that beginning with the first payment of rent 
   next due, rent shall no longer be paid in monthly installments but shall be 
   payable quarterly three (3) months in advance and/or (ii) to require that 
   Tenant increase the amount, if any, of the Security Deposit by one hundred 
   percent (100%), which additional Security Deposit shall be retained by 
   Landlord, and may be applied by Landlord, in the manner provided for Security
   Deposits in this Lease.

D. NO WAIVER

   Neither assessment nor acceptance of partial payments, interest or late 
   charges by Landlord shall constitute a waiver of Tenant's default with 
   respect to such overdue amount, nor prevent Landlord from exercising any of
   its other rights and remedies under this Lease. Nothing contained in this 
   Section shall be deemed to condone, authorize, sanction or grant to Tenant 
   an option for the late payment of rent, additional rent or

   other sums due thereunder, and Tenant shall be deemed in default with
   regard to any such payments should the same not be made by the date on which
   they are due.

SECTION XXII. LIEN FOR RENT

IN CONSIDERATION OF THE MUTUAL BENEFITS ARISING UNDER THIS LEASE, TENANT
HEREBY GRANTS TO LANDLORD A LIEN AND SECURITY INTEREST IN ALL PROPERTY OF
TENANT (INCLUDING, BUT NOT LIMITED TO, ALL FIXTURES, MACHINERY, EQUIPMENT,
FURNISHINGS, AND OTHER ARTICLES OF PERSONAL PROPERTY NOW OR HEREAFTER PLACED
IN OR ON THE PREMISES BY TENANT, TOGETHER WITH THE PROCEEDS FROM THE 
DISPOSITION OF THOSE ITEMS TOGETHER WITH ALL ITEMS OF COLLATERAL DESCRIBED IN
EXHIBIT A TO EXHIBIT H HERETO, WHICH EXHIBIT A IS HEREBY INCORPORATED HEREIN BY 
REFERENCE) [THE "COLLATERAL"], NOW OR HEREAFTER PLACED IN OR ON THE PREMISES,
AS SECURITY FOR PAYMENT OF ALL RENT AND OTHER SUMS AGREED TO BE PAID BY 
TENANT HEREIN. THE PROVISIONS OF THIS SECTION (XXII.) CONSTITUTE A SECURITY 
AGREEMENT UNDER THE UNIFORM COMMERCIAL CODE OF THE STATE IN WHICH THE 
BUILDING IS LOCATED, AND LANDLORD HAS AND MAY ENFORCE A SECURITY INTEREST IN
THE COLLATERAL. THE COLLATERAL SHALL BE REMOVED WITHOUT THE CONSENT OF 
LANDLORD UNTIL ALL ARREARAGES IN RENT AND OTHER SUMS OF MONEY THEN DUE TO 
LANDLORD HEREUNDER HAVE BEEN PAID AND DISCHARGED. CONCURRENTLY WITH THE 
EXECUTION AND DELIVERY HEREOF, TENANT SHALL EXECUTE, AS DEBTOR, TWO OR MORE 
FINANCING STATEMENTS IN THE FORM ATTACHED HERETO AS EXHIBIT H, TO PERFECT 
THIS SECURITY INTEREST PURSUANT TO THE UNIFORM COMMERCIAL CODE OF THE STATE 
IN WHICH THE BUILDING IS LOCATED. LANDLORD MAY AT ITS ELECTION AT ANY TIME 
FILE A COPY OF THIS LEASE AS A FINANCING STATEMENT. LANDLORD, AS SECURED 
PARTY, HAS ALL THE RIGHTS AND REMEDIES AFFORDED A SECURED PARTY UNDER THE 
UNIFORM COMMERCIAL CODE OF THE STATE IN WHICH THE BUILDING IS LOCATED IN 
ADDITION TO AND CUMULATIVE OF THE LANDLORD'S LIENS AND RIGHTS PROVIDED BY
LAW OR BY THE OTHER TERMS AND PROVISIONS OF THIS LEASE.

SECTION XXIII. HOLDING OVER

   Any holding over by Tenant in the possession of the Premises, or any 
   portion thereof, after the expiration or earlier termination of the Term, 
   with or without the consent of Landlord, shall be construed to be a tenancy 
   from month to month at (97)two hundred percent (200%) of the Monthly Rental 
   herein specified for the last month in the Term (prorated on a monthly basis)
   unless Landlord shall specify a lesser amount for rent in its sole 
   discretion, together with an amount estimated by Landlord for the monthly 
   Common Operating Costs payable under this Lease, and shall otherwise be on 
   the terms and conditions herein specified as far as applicable. Any holding 
   over without Landlord's consent shall constitute a default by Tenant and 
   shall entitle Landlord to pursue all remedies provided in this Lease and 
   Tenant shall be liable for any and all direct or consequential damages or 
   losses of Landlord resulting from Tenant's holding over without Landlord's 
   consent.

SECTION XXIV. ATTORNEYS' FEES

Tenant shall pay to Landlord all amounts for costs and expenses, including, 
but not limited to, reasonable attorneys' fees and amounts paid to any 
collection agency, incurred by Landlord in


- --------------------

(97) one hundred fifty percent (150%)

                                       35

<PAGE>

connection with any breach or default by Tenant under this Lease or incurred 
in order to enforce or interpret the terms or provisions of this Lease. 
Tenant shall also pay to Landlord all such amounts, including attorneys' 
fees, incurred by Landlord in responding to any request by Tenant (a) to 
amend or modify this Lease or (b) to prepare any statement or document in 
connection with this Lease, including without limitation estoppel certificates 
or subordination agreements or the like. Such amounts shall be payable upon 
demand. In addition, if any action shall be instituted by either Landlord or 
Tenant for the enforcement or interpretation of any of its rights or remedies 
in or under this Lease, the prevailing party shall be entitled to recover 
from the losing party all costs incurred by the prevailing party in said 
action and any appeal therefrom, including reasonable attorneys' fees and 
court costs to be fixed by the court therein. In the event Landlord is made a 
party to any litigation between Tenant and any third party, then Tenant shall 
pay all costs and attorneys' fees incurred by or imposed upon Landlord in 
connection with such litigation; provided, however, if Landlord is ultimately 
held to be liable, then Landlord shall reimburse Tenant for the cost of any 
attorneys' fees paid by Tenant on behalf of Landlord.

SECTION XXV.  MORTGAGE PROTECTION/SUBORDINATION

A.   SUBORDINATION

     The rights of Tenant under this Lease are and shall be, at the option of 
     Landlord, either subordinate or superior to any mortgage or deed of 
     trust (including a consolidated mortgagee or deed of trust) constituting 
     a lien on the Premises, Building or Project, or Landlord's interest 
     therein or any part thereof, whether such mortgage or deed of trust has 
     heretofore been, or may hereafter be, placed upon the Premises by 
     Landlord, and to any ground or master lease if Landlord's title to the 
     Premises or any part thereof is or shall become a leasehold interest. To 
     further assure the foregoing subordination or superiority, Tenant shall, 
     upon Landlord's request, together with the request of any mortgagee under 
     a mortgage or beneficiary under a deed of trust or ground or master 
     lessor, execute any instrument (including without limitation an 
     amendment to this Lease that does not materially and adversely affect 
     Tenant's rights or duties under this Lease), or instruments intended to 
     subordinate this Lease, or at the option of Landlord, to make it 
     superior to any mortgage, deed of trust, or ground or master lease.
     Notwithstanding any such subordination, Tenant's right to occupy the 
     Premises pursuant to this Lease shall remain in effect for the full Term
     as long as Tenant is not in default hereunder.

     (98)

B.   ATTORNMENT

     Notwithstanding subsection A. above, Tenant agrees (1) to attorn to any 
     mortgagee of a mortgage or beneficiary of a deed of trust encumbering 
     the Premises and to any party acquiring title to the Premises by 
     judicial foreclosure, trustee's sale, or deed in lieu of foreclosure, 
     and to any ground or master lessor, as the successor to Landlord 
     hereunder, (2) to execute any attornment agreement reasonably requested 
     by a mortgagee, beneficiary, ground or master lessor, or party so 
     acquiring title to the Premises, and (3) that this Lease, subject to the 
     rights under any outstanding non-disturbance agreement, at the option of 
     such mortgagee, beneficiary, or ground or master lessor, or other party, 
     shall remain in force notwithstanding any such judicial foreclosure, 
     trustee's sale, deed in lieu of foreclosure, or merger of titles. 
     Notwithstanding the foregoing, neither a


- -----------------------
     (98)   Notwithstanding the foregoing, this Lease shall not be subordinate 
            to any future encumbrance in favor of Landlord's lender for the 
            Project unless and until Tenant, Landlord and such lender shall 
            have mutually executed and delivered a Subordination, 
            Non-Disturbance and Attornment Agreement, substantially in the form 
            of EXHIBIT I hereto (which Tenant shall, upon request by Landlord, 
            execute and deliver, and Tenant's failure to do so within ten 
            (10) days after written demand therefor by Landlord shall 
            constitute a default by Tenant under this Lease).


                                      36

<PAGE>


     mortgagee of a mortgage or beneficiary of a deed of trust encumbering 
     the Premises, any party acquiring title to the Premises by judicial 
     foreclosure, trustee sale, or deed in lieu of foreclosure, or any ground 
     lessor or master lessor, as the successor to Landlord hereunder, shall 
     be liable or responsible for any breach of a covenant contained in this 
     Lease that occurred before such party acquired its interest in the 
     Premises or for any continuing breach thereof until after the successor 
     Landlord has received the notice and right to cure as provided herein, 
     and no such party shall be liable or responsible for any security 
     deposits held by Landlord hereunder which have not been transferred or 
     actually received by such party, and such party shall not be bound by 
     any payment of rent or additional rent for more than two (2) months in 
     advance.

C.   AMENDMENT

     If any lending institution with which Landlord has negotiated or may 
     negotiate for financing for the Building or Project requires any changes 
     to this Lease, Tenant shall promptly execute and deliver an amendment to 
     this Lease prepared by Landlord and embodying such changes, so long as 
     such changes do not materially increase Tenant's obligations (99) 
     hereunder (100). In the event that Tenant shall fail to execute and 
     deliver such amendment within twenty (20) days after receipt thereof by 
     Tenant, such failure shall constitute a default hereunder by Tenant and 
     shall entitle Landlord to all remedies available to a landlord against a 
     defaulting tenant pursuant to a written lease, including but not limited 
     to those remedies set forth in Section XX.

SECTION XXVI.  ESTOPPEL CERTIFICATE/FINANCIAL STATEMENTS

A.   ESTOPPEL CERTIFICATE

     Tenant, at any time and from time to time upon not less than ten (10) 
     days' prior written notice from Landlord, agrees to execute and deliver 
     to Landlord a statement in the form provided by Landlord (a) certifying 
     that this Lease is unmodified and in full force and effect, or, if 
     modified, stating the nature of such modification and certifying that 
     this Lease, as so modified, is in full force and effect and the date to 
     which the rent and other charges are paid in advance, if any; (b) 
     acknowledging that there are not, to Tenant's knowledge, any uncured 
     defaults on the part of Landlord hereunder, or specifying such defaults 
     if they are claimed evidencing the status of this Lease; (c) 
     acknowledging the amount of the Security Deposit held by Landlord;
     and (d) containing such other information regarding this Lease 
     or Tenant as Landlord reasonably requests. (101) Tenant's failure to 
     deliver an estoppel certificate within such time shall be conclusive 
     upon Tenant that (i) this Lease is in full force and effect without 
     modification except as may be represented by Landlord, (ii) to Tenant's 
     knowledge there are no uncured defaults in Landlord's performance, (iii) 
     no rent has been paid in advance except as set forth in this Lease, and 
     (iv) such other information regarding this Lease and Tenant set forth 
     therein by Landlord is true and complete.
     
     
- -----------------------
     (99)   or materially decrease Tenant's rights

     (100)  In no event shall Tenant be required to execute an amendment 
            pursuant to this subsection C. which reduces the Rentable Area of 
            the Premises, increases the Monthly Rental rate(s), changes the 
            base year for the purposes of calculating Tenant's Proportionate 
            Share of Common Operating Costs, deprives Tenant of its options 
            pursuant to Addendum Section XXXV.A., restricts Tenant's ability 
            to access or use the Premises for the Permitted Use, reduces the 
            parking spaces available to Tenant or requires Tenant to use 
            Landlord's provider of janitorial services.

     (101)  Upon Tenant's written request therefor, Landlord agrees to 
            deliver to Tenant, not more than twice per calendar year, an 
            estoppel certificate containing information of the type described 
            in clauses (a) through (d) of the previous sentence.


                                      37

B.   FURNISHING OF FINANCIAL STATEMENTS

Landlord has reviewed the financial statements, if any, requested of the 
Tenant and has relied upon the truth and accuracy thereof with Tenant's 
knowledge and representations of the truth and accuracy of such 
statements and that said statements accurately and fairly depict the 
financial condition of Tenant. Said financial statements are an inducing 
factor and consideration for the entering into of this Lease by Landlord 
with this particular Tenant. Tenant shall, at any time and from time to 
time (102) upon not less than ten (10) days' prior written notice from 
Landlord, furnish Landlord with (a) Tenant's most recent audited 
financial statements, including a balance sheet and income statement, or 
a document in which Tenant states that its books are not independently 
audited (103) and (b) unaudited financial statements, including a 
balance sheet and income statement, dated within ninety (90) days of the 
request from Landlord. (104)

SECTION XXVII.  PARKING                            SEE ADDENDUM SECTION XXXV.H.

Landlord agrees to maintain or cause to be maintained an automobile parking 
area and to maintain and operate, or cause to be maintained and operated, 
said automobile parking area during the Term of this Lease for the benefit 
and use of the customers, service suppliers, other invitees and employees of 
Tenant. Whenever the words "automobile parking area" or "parking area" are 
used in this Lease, it is intended that the same shall include, whether in a 
surface parking area or a parking structure, the automobile parking stalls, 
driveways, loading docks, truck areas, service drives, entrances and exits 
and sidewalks, landscaped areas, pedestrian passageways in conjunction 
therewith and other areas designed for parking. Landlord shall keep said 
automobile parking area in a neat, clean and orderly condition, lighted and 
landscaped, and shall repair any damage to the facilities thereof, the cost 
of which shall be included in Common Operating Costs. Nothing contained 
herein shall be deemed to impose liability upon Landlord for personal injury 
or theft, for damage to any motor vehicle, or for loss of property from 
within any motor vehicle, which is suffered by Tenant or any of its 
employees, customers, service suppliers or other invitees in 
connection with their use of said automobile parking area. Landlord shall 
also have the right to establish such reasonable rules and regulations as may 
be deemed desirable, at Landlord's sole discretion, for the proper and 
efficient operation and maintenance of said automobile parking area. Such 
rules and regulations may include, without limitation, (i) restrictions in 
the hours during which the automobile parking area shall be open for use and 
(ii) (105) the establishment of charges for parking therein (on either a 
reserved or unreserved basis, at Landlord's sole discretion) by tenants of 
the Building and Project as well as by their employees, customers and service 
suppliers.

Landlord shall at all times during the Term hereof have the sole and 
exclusive control of the automobile parking area, and may at any time during 
the Term hereof exclude and restrain any person from use or occupancy 
thereof; excepting, however, Tenant and employees, customers, service 
suppliers and other invitees of Tenant and of other tenants in the Building 
and Project who make use of said area in accordance with any rules and 
regulations established by Landlord from time to time with respect thereto. 
The rights of Tenant and its employees, customers, service suppliers and 
invitees referred to in this Section XXVII. shall at all times be subject to 
(i) the rights of Landlord and other tenants in the Building and Project to 
use the same in common with Tenant and its employees, customers, service 
suppliers and invitees, (ii) the availability of parking spaces in said 
automobile parking area, and (iii) Landlord's right to

     (102)  (but no more frequently than quarterly)

     (103)  or, if Tenant's stock is publicly traded, Tenant's most recent 
            10K report.

     (104)  Landlord will keep such statements confidential and not disclose 
            such statements, except to any person or entity to whom Landlord 
            is permitted to disclose the terms of this Lease pursuant to 
            Section XXXII.R.

     (105)  subject to Addendum Section XXXV.H.
                                      38

<PAGE>


change the location of any assigned reserved parking spaces in such instances 
as shall be determined at Landlord's sole discretion. (106) Notwithstanding 
Landlord's exclusive control and obligations to provide a parking area, 
Landlord is not responsible or liable for any damage to any automobiles or 
persons in the parking area.

SECTION XXVIII.  SIGNS; NAME OF BUILDING           SEE ADDENDUM SECTION XXXV.I.

Tenant shall not have the right to place, construct, or maintain on or about 
the Premises, Building or Project, or in any interior portions of the 
Premises that may be visible from the exterior of the Building or Common 
Areas, any signs, names, insignia, trademark, advertising placard, 
descriptive material or any other similar item ("Sign") without Landlord's 
prior written consent, which consent may be withheld in Landlord's sole 
discretion; provided, however, any Signs are further subject to approval of 
any applicable governmental authority and/or compliance with applicable 
governmental requirements. In the event Landlord consents to Tenant placing a 
Sign on or about the Premises, Building or Project, any such Sign shall be 
subject to Landlord's approval of the color, size, style and location of such 
Sign, and shall conform to any current or future Sign criteria established by 
Landlord for the Building or Project. If Landlord enacts a Sign criteria or 
revises an existing Sign criteria, after Tenant has erected a Sign to which 
Landlord has granted its consent, if Landlord so elects, Tenant agrees, 
at Landlord's expense, subject to Landlord's prior approval of the cost 
thereof, to make the necessary changes to its Sign in order to conform the 
Sign to Landlord's Sign criteria, as enacted or revised, provided that such 
changes shall be limited to the color, size, style and location of Tenant's 
Sign and that Tenant shall not be required to change the content of its Sign. 
In the event Landlord consents to Tenant's placement of a Sign on the 
Building, Tenant shall, at its sole cost, remove such Sign from the Building 
at the end of the Term, restore the Building to the same condition as before 
the installation of the Sign, ordinary wear and tear excepted and remove any 
discoloration of the Building caused by the presence of such sign.

Landlord reserves the right at any time it deems necessary or appropriate to 
(a) place Signs at any location on the Building and Project as it deems 
necessary and (b) change the name, address or designation of the Building and

Landlord and to the holder(s) of the indebtedness or other obligations 
secured by any mortgage or deed of trust affecting the Premises as

SECTION XXXIII.  GENERAL

A.   PARAGRAPH HEADINGS

     The paragraph headings used in this Lease are for the purposes of

     meaning of any part of this Lease.

B.   INCORPORATION OF PRIOR AGREEMENTS; AMENDMENTS

     TENANT MAY NOT REPLY ON ANY SUCH INCONSISTENT REPRESENTATION OR WARRANTY.

C.   WAIVER

     Any waiver by Landlord of any breach of any term, covenant, or condition 
     contained in this Lease shall not be deemed to be a waiver of such term, 
     covenant, or condition or of any subsequent breach of the same or of any 
     other term, covenant, or condition contained in this Lease. Landlord's 
     consent to, or approval of, any act shall not be deemed to render 
     unnecessary the obtaining of Landlord's consent to, or approval of, any 
     subsequent act by Tenant. The acceptance of rent or other sums payable 
     hereunder by Landlord shall not be a waiver of any preceding breach by 
     Tenant of any provision hereof, other than failure of Tenant to pay the 
     particular rent or other sum so accepted, regardless of Landlord's 
     knowledge of such preceding breach at the time of acceptance of such 
     rent, or sum equivalent to rent.

     counsel for Landlord, and Landlord may, in its sole discretion, record 
     such short form or memorandum in the county where the Premises are 
     located. Tenant shall not record this Lease, or a short form or 
     memorandum of this Lease, without Landlord's prior written consent.

     Time is of the essence in the performance of each provision of this 
     Lease.

F.   EXAMINATION OF LEASE

     effective as a lease or otherwise until execution by and delivery to 
     both Landlord and Tenant.

G.   SEVERABILITY

     If any term or provision of this Lease or the application thereof to any 
     person or circumstance shall, to any extent, be invalid or 
     unenforceable, the remainder of this Lease, or the application of such 
     term or provision to persons or circumstances other than those as to 
     which it is held invalid or unenforceable, shall not be affected 
     thereby, and each term and provision of this Lease shall be valid and be 
     enforced to the fullest extent permitted by law.


H.   SURRENDER OF LEASE NOT MERGER

     Neither the voluntary or other surrender of the Lease by Tenant nor the 
     mutual cancellation thereof shall cause a merger of the titles of 
     Landlord and Tenant, but such surrender or cancellation shall, at the 
     option of Landlord, either terminate all or any existing subleases or 
     operate as an assignment to Landlord of any such subleases.

     material or labor, restriction by any governmental authority, civil 
     riot, flood, and any other cause not within the control of (110) 
     Landlord, then the period for (111) Landlord's performance of the 
     provision shall be automatically extended for the same time (112) 
     Landlord is so delayed or hindered. (113)

     bringing of any claim or action with respect to which indemnification may 
     be claimed by the indemnified party against the indemnifying party under 
     such provision or (b) the date on which any claim or action for which 
     indemnification may be claimed under such provision is fully and finally 
     resolved and, if applicable, any compromise thereof or judgment or award 
     thereon is paid in full by the indemnifying party and the indemnified 
     party is reimbursed by the indemnifying party for any amounts paid by 
     the indemnified party in compromise thereof or upon a judgment or award 
     thereon and in defense of such action or claim, including reasonable

                                   DATED SEPTEMBER __, 1996


SECTION XXXV. ADDENDUM

A.  PREMISES

    (1)    RIGHT OF FIRST REFUSAL

           During the twelve (12) month period commencing on the 
           Lease Commencement Date, Tenant shall have a one-time right of 
           first refusal to lease the second floor of the Building (the 
           "Expansion Space") from Landlord if, after the Lease Commencement 
           Date and during the initial Term of this Lease, Landlord is or 
           becomes interested in marketing such space. Landlord shall notify 
           Tenant in writing upon receipt by Landlord from a third party of 
           an offer for any portion of the Expansion Space (including all) 
           that Landlord desires to accept. Tenant shall, within (5) 
           business days following its receipt of Landlord's notice, 
           indicate in writing its intention to add to the Premises the 
           entire portion of the Expansion Space (including all) so offered 
           by Landlord on the terms and conditions specified herein. Any 
           failure by Tenant to respond to Landlord's notice within such 
           five (5) business day period, or any notice by Tenant specifying 
           Tenant's acceptance of the Expansion Space on terms other than 
           those set forth herein or of only a portion of the Expansion 
           Space so offered by Landlord, shall cause Tenant's rights under 
           this subsection A.(1) to terminate with respect to the Expansion 
           Space so offered, and Landlord shall thereafter be free to lease 
           the Expansion Space so offered to another party at any rate and 
           on any terms Landlord chooses.

           If Tenant is entitled to and gives notice to Landlord 
           within such five (5) business days of its desire to add the 
           offered Expansion Space to the Premises, the entire Expansion 
           Space shall be added to the Premises on the following terms and 
           conditions: the Expansion Space so offered shall be delivered by 
           Landlord to Tenant as soon as the same is available and shall be 
           added to the Premises on the same terms and conditions set forth 
           in this Lease with respect to the Premises (except that the 
           Security Deposit for the Expansion Space shall be prorated such 
           that Tenant shall deposit an amount equal to $1.455 per square 
           foot of Rentable Area within the Expansion Space (per year) of 
           the balance of the Term with respect to such Expansion Space, the 
           Tenant Allowance shall be an amount equal to $2.50 per square 
           foot of Rentable Area within the Expansion Space per year of the 
           balance of the Term with respect to the Expansion Space and the 
           Lease Commencement Date with respect to the Expansion Space shall 
           be a date selected by Landlord as the date for Substantial 
           Completion of Landlord's Work therein) AND the balance of the 
           Expansion Space (i.e., the portion of the Expansion Space, if 
           any, not covered by the third party offer) shall be added to the 
           Premises and delivered by Landlord to Tenant on the day before 
           the first anniversary of the date Landlord's notice offering 
           Tenant the Expansion Space was given (or sooner, if mutually 
           agreed in writing by Landlord and Tenant), on the terms and 
           conditions set forth herein with respect to the Expansion Space 
           identified in Landlord's notice.

           Notwithstanding anything to the contrary contained in this 
           subsection A.(1), Landlord shall be required to offer any portion 
           of the Expansion Space (including all) to Tenant, and Tenant 
           shall be entitled to exercise its rights hereunder with respect 
           thereto, only if, at the time of such offer and exercise, 
           respectively, Tenant is not in default under any of the terms, 
           conditions, provisions or

                                       45

<PAGE>

           covenants of this Lease, and there has not then occurred an event 
           which, with notice and/or lapse of time, would constitute such a 
           default.

    (2)    OPTION TO EXPAND

           During the twelve (12) month period commencing on the Lease 
           Commencement Date, and so long as no event has previously 
           occurred giving rise to Landlord's obligations to give notice to 
           Tenant pursuant to clause (1) of this subsection A. above, Tenant 
           shall have the option to lease the entire Expansion Space by 
           giving to Landlord written notice of its election to do so. 
           Provided that Tenant is entitled to and gives notice to Landlord 
           as provided in the foregoing sentence, the entire Expansion Space 
           shall be added to the Premises as soon as the same is available 
           on the terms and conditions set forth herein with respect to the 
           Premises (except that the Security Deposit for the Expansion 
           Space shall be prorated such that Tenant shall deposit an amount 
           equal to $1.455 per square foot of Rentable Area within the 
           Expansion Space per year of the balance of the Term with respect 
           to such Expansion Space, the Tenant Allowance shall be an amount 
           equal to $2.50 per square foot of Rentable Area within the 
           Expansion Space per year of the balance of the Term with respect 
           to the Expansion Space and the Lease Commencement Date with 
           respect to the Expansion Space shall be a date selected by 
           Landlord as the date for Substantial Completion of Landlord's 
           Work therein). Notwithstanding anything to the contrary contained 
           in this subsection A.(2), Tenant shall be entitled to exercise 
           its rights hereunder with respect to the Expansion Space only if, 
           at the time of such offer and exercise, respectively, Tenant is 
           not in default under any of the terms, conditions, provisions or 
           covenants of this Lease, and there has not then occurred an event 
           which, with notice and/or lapse of time, would constitute such a 
           default.

B.  OPTIONS TO EXTEND TERM

    Provided that Tenant is not in default hereunder either at 
    the date Tenant's notice of exercise is given or on the date an 
    Additional Term (as defined below) would otherwise commence, 
    Tenant shall have the option to extend the Term with respect to 
    the entire Premises then leased to Tenant by two (2) additional 
    periods of five (5) years each (each, an "Additional Term"). 
    Tenant's option for the first Additional Term (the "First 
    Additional Term") shall be exercised, if at all, by written 
    notice to Landlord given at least six (6) and no more than nine 
    (9) months prior to the Expiration Date determined pursuant to 
    Section I. of this Lease. Tenant's option for the second 
    Additional Term, if any (the "Second Additional Term"), shall be 
    exercisable by Tenant only if Tenant has previously exercised the 
    option for the First Additional Term and shall be exercised, if 
    at all, by written notice to Landlord given at least six (6) and 
    no more than nine (9) months prior to the expiration date of the 
    First Additional Term. If Tenant is entitled to and gives notice 
    in the manner and within the time set forth in this subsection 
    B., then the Term shall be extended by the applicable Additional 
    Term, on all of the conditions set forth in this Lease for the 
    Premises for original Term, except that parking rates shall be at 
    then-current fair market value:

    (1)    Monthly Rental for each Additional Term shall be determined as 
           follows:

           (a)    Monthly Rental for each Additional Term 
                  shall be 95% of fair market rental rate or rates for 
                  comparable buildings (considering size, age, quality, 
                  utility, location, access, improvements and amenities) 
                  located within the general geographic location of the 
                  Project, as reasonably determined by Landlord. Landlord 
                  shall, upon receipt of Tenant's notice provided for above 
                  and at least three (3) months prior to the then-current 
                  Expiration Date, notify Tenant in writing of its 
                  determination of the fair market rental rate or rates for 
                  parking and for the purpose of determining Monthly Rental 
                  for the ensuing Additional Term.

           (b)    Within ten (10) days after such notice is given, Tenant may 
                  elect in written notice to Landlord either to (i) 
                  unequivocally accept such Monthly Rental for the ensuing 
                  Additional Term as determined by Landlord or (ii) submit the 
                  matter of the fair market value for the purpose of determining
                  Monthly rental (only) to appraisal in accordance with (c) 
                  below. Tenant's failure to make a written election strictly 
                  in accordance with the preceding sentence shall be deemed to 
                  be an acceptance of the Monthly Rental as determined by 
                  Landlord, EXCEPT that an equivocal acceptance of the Monthly 
                  Rental shall be deemed an election by Tenant to submit the 
                  matter of the fair market value for the purpose of 
                  determining Monthly rental (only) to appraisal in accordance 
                  with (c) below; and

           (c)    If Tenant elects or is deemed to have 
                  elected to submit the matter to appraisal in accordance 
                  with (b) above, then each party shall, by written notice 
                  to the other party given within ten (10) days after such 
                  election or deemed election by Tenant, select an 
                  appraiser. If either party shall fail to select an 
                  appraiser in such manner and within such time, the single 
                  appraiser actually selected shall perform the appraisal. 
                  If each party timely and properly selects an appraiser, 
                  the two appraisers selected by the parties shall determine 
                  and attempt to agree on the fair market rental value for 
                  the ensuing Additional Term within thirty (30) days after 
                  their appointment; if they are unable to so agree and 
                  their appraised values differ by more than five percent 
                  (5%) in the aggregate over the ensuing Additional Term, 
                  the two appraisers shall, by written notice to Landlord 
                  and Tenant, select a third appraiser within five (5) days 
                  after expiration of the thirty (30) day period within 
                  which they were to determine and agree on the fair market 
                  rental, which third appraiser shall analyze the fair 
                  market rental for the ensuing Additional Term. If they 
                  cannot agree on a third appraiser within such time period, 
                  or if both parties fail to select an appraiser in the 
                  manner and within the time herein provided, either party 
                  may have the third (or sole, if applicable) appraiser 
                  appointed by application to the presiding judge of the Los 
                  Angeles County Superior Court or his or her designee. If 
                  the appraised values of the first two appraisers are 
                  within five percent (5%) in the aggregate over the ensuing 
                  Additional Term, then Landlord shall calculate the average 
                  of the two appraised values as a flat rental rate for the 
                  ensuing Additional Term, which average shall be the fair 
                  market rental rate for such Additional Term.

                  The appraisers shall have the MAI designation and a 
                  minimum of ten (10) years experience in the Los Angeles 
                  County (Glendale/Pasadena) office market. Each of the 
                  first two appraisers shall analyze the fair market rental 
                  value of the Premises and shall give written notice to the 
                  parties of his or her appraisal within thirty (30) days 
                  following his or her appointment or selection, but in no 
                  event later than the commencement of the Additional Term. 
                  If a single appraiser is used, his or her determination 
                  shall be the fair market rental rate. If three appraisers 
                  are used, the third appraiser shall select one of the 
                  values determined by the first two appraisers as the fair 
                  market rental rate. The cost of the appraisals shall be 
                  shared equally by Landlord and Tenant;

    (2)    The provisions of Sections III.B. and C. and EXHIBIT C shall not 
           apply to the Additional Term; and

    (3)    In the case of the First Additional Term, there shall 
           be one further option to extend the Term, and, in the case of the 
           Second Additional Term, there shall be no further options to 
           extend the Term. In the event Tenant fails or is not entitled to 
           exercise its option for the First Additional Term, or Tenant is 
           deemed



                                       47

<PAGE>

           (pursuant to (1)(b) above) to have elected to terminate the Lease 
           upon receipt of Landlord's notice of the fair market rental for 
           the First Additional Term, then Tenant's option for the Second 
           Additional Term shall lapse and shall thereafter not be 
           exercisable by Tenant.

C.  COMMON OPERATING COSTS

    (1)    As used in this Lease, the term "Project Operating 
           Costs" shall include all costs of the type included in Common 
           Operating Costs applicable to the Common Areas and/or the Project 
           in general, such as real property taxes applicable to the Common 
           Areas, liability insurance with respect to the Common Areas, 
           maintenance service for the buildings within the Project and 
           repair costs with respect to the Project or any equipment or 
           machinery therein, but excluding costs which are directly and 
           separately identifiable to the operation and maintenance of the 
           Building or other buildings within the Project. Common Operating 
           Costs shall also include the Building's share of Project 
           Operating Costs, which shall include, as appropriate, liability 
           and other insurance with respect the the Project generally, 
           expenses of operating and maintaining the parking structures, 
           landscaping expenses for exterior landscaping within the Project, 
           security services for the Project, property management fees and 
           costs for a manager and fees and other charges in connection with 
           membership in energy conservation associations and traffic 
           management organizations. To the extent that, in Landlord's sole 
           but reasonable judgment, it may not be equitable to allocate 
           certain Project Operating Costs on a pro rata basis based upon 
           the Rentable Areas of the buildings in the Project, as the case 
           may be, then Landlord may allocate the same on such basis as 
           Landlord, in its sole but reasonable judgment, determines to be 
           equitable.

    (2)    Notwithstanding anything to the contrary in the Lease, 
           Tenant's Proportionate Share of any and all costs of providing 
           janitorial service to the Premises which are includable in Common 
           Operating Costs in accordance with this Lease shall be payable by 
           Tenant, commencing on the Lease Commencement Date and on the 
           first day of each calendar month in the Term thereafter, without 
           any deduction for the Base Operating Expense attributable to such 
           janitorial services. In addition, electrical service to the 
           Premises will be separately metered, and Tenant shall pay such 
           separately metered costs directly to the providers of such 
           utilities as provided in Section IX.A. of the Lease. Accordingly, 
           costs attributable to tenant-area janitorial services and/or to 
           tenant-area electrical shall be excluded from the Base Operating 
           Expense, and Tenant's Proportionate Share of all Common Operating 
           Costs, other than such janitorial and electrical utility costs, 
           shall be determined by reference to the Base Operating Expense, 
           as so reduced.

    (3)    In the event that during all or any portion of any 
           calendar year, including the year used in calculating the Base 
           Operating Expense, the Building is not assessed as a completed 
           building, at such time as the Building is thereafter assessed as 
           a fully completed building, Landlord shall make an adjustment to 
           the Common Operating Costs for such year (including the year for 
           the Base Operating Expense, if applicable) employing sound 
           accounting and management principles, to reflect the Common 
           Operating Costs that would have been paid or incurred by Landlord 
           had the Building been fully completed. In no event shall Landlord 
           be entitled to recover from tenants of the Project more than one 
           hundred percent (100%), in the aggregate, of the increase in 
           Common Operating Costs actually incurred by Landlord.

    (4)    Notwithstanding the foregoing, the follow shall not be included in 
           Common Operating Costs (or shall be deducted therefrom if included 
           therein):

           (a)    Costs incurred by Landlord in performing or providing special 
                  work or services to a particular tenant of the Project at 
                  such tenant's cost, and



                                       48

<PAGE>


               costs of any additions, changes, replacements and other items
               to tenant-area premises which are made exclusively to prepare
               for a new tenant's occupancy and which benefit only that
               particular tenant;

          (b)  Compensation paid to officers and executives of Landlord and of
               Landlord's managing agent who are not directly involved in the
               management of the Project;

          (c)  Costs which were previously included in Common Operating Costs
               for either the base year (i.e., 1997) or any other year during
               the Term which are reimbursed to Landlord by insurance or
               condemnation proceeds, under warranty or otherwise outside of
               Common Operating Costs;

          (d)  Costs of repairs or restoration incurred by reason of fire or
               other casualty if and to the extent that Landlord failed to
               obtain insurance against such fire or casualty, if such insurance
               was available at commercially reasonable rates and was required
               to be carried by Landlord pursuant to this Lease; provided,
               however, that the foregoing shall not apply to preclude Landlord
               from including in Common Operating Costs the deductible amounts
               under insurance policies maintained by Landlord;

          (e)  Any financing or refinancing costs and expenses secured by real
               estate within the Project including, but not limited to,
               interest or amortization on debt and rent under any ground or
               underlying lease;

          (f)  Any real estate brokerage commissions or other costs incurred in
               procuring tenants or any fee or other form of compensation in
               lieu of such commission;

          (g)  Any media advertising or any other advertising expenses incurred
               in connection with the marketing of the Building or any rentable
               space therein; provided, however, that the foregoing shall not
               apply to preclude Landlord from including in Common Operating
               Costs, costs incurred in connection with signage for the Project
               which is not exclusively for marketing purposes;

          (h)  Costs of capital repairs, replacements or improvements (as
               reasonably determined by Landlord) except: (i) to the extent the
               same are amortized over the reasonable useful life of the item
               as reasonably determined by Landlord and included in Common
               Operating Costs as so amortized, or (ii) those designed to
               reduce Common Operating Costs; provided, however, in no
               event shall the foregoing apply to preclude Landlord from
               including in Common Operating Costs, costs of routine maintenance
               and repair;

          (i)  Rental payments for base building equipment, such as HVAC
               equipment and elevators, which, if purchased by Landlord, would
               be excluded from Common Operating Costs pursuant to item (h)
               above; provided, however, in no event shall the foregoing
               preclude Landlord from including in Common Operating Costs rental
               payments for equipment leased temporarily (e.g., in order to
               facilitate repair or replacement of Building equipment) or
               equipment leased to perform routine maintenance and repair
               (e.g., window washing equipment);

          (j)  Depreciation or amortization which would be excluded pursuant to
               items (h) or (i) above;


                                      49


<PAGE>



          (k)  Costs for materials or services paid to a related person or
               entity, if and to the extent that such costs exceed the amount
               that would have been paid if the services or materials had been
               procured from an unrelated person or entity;

          (l)  Costs incurred by Landlord due to the violation by Landlord of
               the terms and conditions of any lease of space in the Building
               or the Project which would not otherwise be included in Common
               Operating Costs in the absence of such default;

          (m)  Fines or penalties for late payments or non-compliance with laws
               assessed against Landlord as a result of Landlord's negligence;

          (n)  Painting or decorating space in the Project other than the Common
               Areas and/or the management office at the Building; and

          (o)  Costs incurred in connection with bringing the Premises,
               Building, Project or Common Areas into initial compliance with
               any laws as in effect and as applicable thereto as of the date of
               this Lease.


     (5)  Upon receipt of Tenant's notice protesting an Annual Statement
          delivered to Tenant by Landlord pursuant to Section V.C. of the
          Lease, Landlord will provide to Tenant reasonable documentary 
          back-up for those item(s) protested by Tenant. Tenant shall pay to 
          Landlord upon demand as additional rent the costs and expenses
          incurred by Landlord in responding to such request. In the event
          that, upon reviewing the back-up so provided by Landlord, Tenant
          disagrees with the amount charged by Landlord to Tenant for any
          such item, Tenant may so notify Landlord. If Landlord agrees with
          the findings of Tenant, then an appropriate adjustment shall be made.
          In the event that there is a disagreement, then Landlord and Tenant
          shall each identify an accountant, who shall meet to resolve the
          dispute, whose determination shall be binding upon Landlord and
          Tenant. Any such dispute must be resolved within nine (9) months
          after the end of the year to which the Annual Statement applies.

D.   SECURITY DEPOSIT

     All or any portion of the Security Deposit described in Section I.L. of
     the Lease may be provided by Tenant in the form of one or more 
     irrevocable letters of credit from an independent financial institution
     selected by Tenant and acceptable to Landlord in the form of EXHIBIT "I"
     hereto (collectively (if applicable) the "Letter of Credit"). If Tenant
     elects to provide a Letter of Credit to satisfy all or a portion of its
     obligations pursuant to Sections I.L. and VI. of the Lease, Tenant shall
     deliver to Landlord, concurrently with the execution and delivery of this
     Lease, cash and/or a Letter of Credit in the aggregate amount of Eight
     Hundred Thousand Dollars ($800,000.00) as security for Tenant's full and
     faithful performance of its obligations and payment of amounts due 
     pursuant to this Lease. Notwithstanding anything to the contrary herein,
     in no event shall Landlord be required to accept a letter of credit in
     excess of, in the aggregate, Four Hundred Thousand Dollars ($400,000.00)
     from any one financial institution. Notwithstanding the foregoing
     sentence, (a) Landlord hereby agrees that the Letter of Credit initially
     provided to Landlord upon execution and delivery of this Lease may be
     drawn on Union Bank of California in the entire amount required to be
     posted (i.e., $800,000.00) and (b) prior to renewing the Letter of Credit
     annually, Tenant shall give notice to Landlord of the financial
     institution(s) with whom Tenant proposes to renew the Letter of Credit 
     for the ensuing year, and Landlord shall have the right to approve such
     financial institution(s) for the renewal Letter of Credit, and may 
     require Tenant to provide two Letters of Credit if the aggregate amount
     thereof is greater than Four Hundred Thousand Dollars ($400,000.00) if
     Landlord, in its sole but reasonable discretion, deems the financial 
     strength of the proposed financial institution to be insufficient. 
     Any Letter of Credit

 
                                      50


<PAGE>

     provided hereunder shall be as available to Landlord as if the same were
     a cash security deposit made pursuant to Section VI. of the Lease. Any
     such Letter of Credit shall be renewed by Tenant annually, on or before
     its expiration date and, if Landlord does not receive an original 
     replacement letter of credit at least three (3) business days prior to 
     the expiration date of an expiring Letter of Credit, then Landlord shall
     have the right to draw the as-yet unexpired Letter of Credit in full;
     provided, however, that in the absence of the occurrence, prior to the 
     applicable anniversary date set forth below, of any event giving rise to
     Landlord's right to use, apply or retain all or any part of the Security
     Deposit pursuant to Section VI. of the Lease (herein, an "Event"), then 
     Tenant's obligation shall be to renew the Letter of Credit in an 
     applicable amount (in the aggregate, if applicable, with other Letters of
     Credit provided hereunder) set forth below. The occurrence of an Event
     prior to any anniversary date set forth below shall cause Tenant's
     obligation to provide the Letter of Credit pursuant to this Addendum
     Section to continue thereafter without any of the subsequent reductions
     described herein.


     Anniversary Date             Amount of Renewed Letter of Credit
     ----------------             ----------------------------------
     1st "Anniversary"*           $700,000.00
     2nd  Anniversary             $600,000.00
     3rd  Anniversary             $500,000.00
     4th  Anniversary             $400,000.00
     5th  Anniversary             $300,000.00
     6th  Anniversary             $200,000.00
     7th  Anniversary             $100,000.00
     8th  Anniversary             -0-

     As used in the foregoing table, the term "Anniversary" refers to the
     applicable anniversary of the Lease Commencement Date specified in the
     table.

E.   HAZARDOUS MATERIALS

     (1)  To the best of Landlord's knowledge, Landlord has not itself used 
          the Building or Project in violation of governmental laws and
          regulations governing Hazardous Materials applicable to the Project
          and, Landlord's actual knowledge, the Building does not contain any
          Hazardous Materials in violation of law and/or friable asbestos,
          and the only non-friable asbestos discovered in the Building is in
          roofing materials located on the roof of the Building. 
          Notwithstanding anything to the contrary in this Lease, in the event
          that Hazardous Materials are discovered in the Project, the presence
          of which is not caused by a breach of the obligations of Tenant set
          forth in Section VI.C. of the Lease, Landlord shall, at Landlord's
          sole cost and expense, remove, remediate, or otherwise deal with
          such Hazardous Materials if, as and when required by applicable
          governmental authorities.

     (2)  Due to the former existence of a landfill in the area of the 
          Project, a methane venting system has been installed at the Project
          and on adjacent properties. In addition, a nearby property owner,
          whose property is closer to the Southern California Edison (SCE)
          power lines which are in the general geographic area of the Project,
          has experienced some interference with MacIntosh computers adjacent
          to the walls of its premises nearest the power lines, which may be
          caused by electric and magnetic fields which may be being induced
          by the SCE power lines. Landlord is unaware of any similar or
          related complaints from the occupant of the other building at the
          Project or from the former occupant of the Building. Information
          with respect to the possible effects of power lines on equipment
          and human health is available from SCE, and Landlord will make
          available to Tenant upon request a copy of such SCE information and
          any other environmental reports in Landlord's possession regarding
          the Project. Tenant accepts the Premises "AS-IS" with respect to the
          SCE power lines and the effect thereof.

F.   SERVICE AND UTILITIES
 
     Access to the Building is available 24 hours per day, 7 days per week via
     a card-key security system. Landlord may assess a charge for any access
     cards for such system provided to Tenant and/or its employees. Utilities
     are, subject to Section XXXIII.K. below, available 24 hours per day,
     subject to Tenant's payment to Landlord of the reasonable costs thereof,
     as determined by Landlord. In the event that the Premises are not
     separately zoned such that after-hours HVAC can be made available to the
     Premises (only), and Tenant requests after-hours HVAC service to the
     Premises at the same time as a tenant or occupant of another area of the
     Building which is in the same zone as the Premises requests the same,
     then (unless the fees to Tenant and such other tenant or occupant are
     prorated by Landlord) any fees received by Landlord for such after-hours
     HVAC from such other tenant or occupant for any period of time for which
     Tenant is assessed a charge for after-hours HVAC shall be applied to
     reduce the charge imposed on Tenant.

G.   JANITORIAL SERVICE

     So long as Tenant is the only occupant of the Building, Tenant may 
     provide janitorial service to the Premises, the scope and the provider
     of which are subject to Landlord's prior written approval. Landlord
     hereby approves Omni Facility Group of Pasadena as the initial provider
     of Tenant's janitorial service; provided, however, that Landlord reserves
     the right to approve the proposed scope of such provider's service and 
     the contract therefor, and further reserves the right to require Tenant
     to replace such provider (and any subsequent provider) if Landlord
     determines that health, cleanliness or maintenance conditions are 
     adversely affected by the standard and level of service provided. If
     Tenant elects to contract directly for janitorial service, Tenant shall
     provide to Landlord a copy of the contract therefor for Landlord's
     approval. In the event that another tenant or occupant takes occupancy of
     the Building, Landlord shall have the right to require that janitorial
     service to the Premises be provided by Landlord's contractor, at Tenant's
     cost as provided in Addendum Section XXXV.C.(2) above, in accordance with
     Landlord's standard janitorial specifications, a copy of which are
     attached to the Lease as EXHIBIT G, but which are subject to change from
     time to time.

H.   PARKING

     Landlord shall make available for the use of Tenant, its employees,
     contractors, agents and invitees up to 4 unreserved parking spaces per
     1,000 square feet of Rentable Area, free of charge (subject to applicable
     governmental requirements) for the initial Term. If and so long as Tenant
     is the only tenant in the Building, Tenant may, with Landlord's prior
     written consent, restrict access to the parking area serving the Building
     so long as Landlord and its agents, employees and invitees are provided
     free access thereto and any improvements in connection therewith are
     treated as "Alterations" within the meaning of Section XII. of the Lease.

I.   SIGNAGE

     Notwithstanding anything to the contrary in Section XXVIII. of the Lease,
     Tenant may install on or before the Lease Commencement Date, at Tenant's
     sole cost and expense, one sign indicating Tenant's name on the Building 
     and may erect a monument sign for the Project, and, on such date (if any)
     as the entire second floor is added to the Premises pursuant to Addendum
     Section XXXV.A. above upon exercise by Tenant of its rights thereunder, a
     second such sign above the entrance to the Building, and in each case the
     contents, design, size, materials, location and method of application of 
     each such sign shall be subject to Landlord's prior written approval and 
     compliance with the CC&Rs for the Project, all applicable sign programs 
     and all other governmental requirements then in effect for the Project.
     From and after the date, if any, that Tenant leases the entire Building,
     and so long as there is no other occupant of the Building, Landlord 
     shall not


                                      52


<PAGE>


     grant to any other person any rights to erect or maintain Building
     identification signage on the Building. In no event shall governmental
     disapproval of any signage for Tenant constitute a default by Landlord
     pursuant to this Lease. Tenant shall be solely responsible to insure all
     signage erected by Tenant pursuant to this subsection I. and to maintain
     such signage in first-class condition at all times; provided, however, if
     Tenant fails to insure, repair or otherwise maintain any such signage
     within ten (10) days after request therefor by Landlord, Landlord may
     obtain insurance and/or perform any necessary repairs or maintenance for
     the account of Tenant, and any and all amounts incurred by Landlord in
     connection therewith shall be due and payable by Tenant to Landlord
     within ten (10) days after demand therefor as additional rent.
     Notwithstanding anything to the contrary in this Lease, upon the
     expiration or earlier termination of this Lease, Tenant shall be
     responsible, as to both cost and performance, for removing Tenant's
     Building sign(s) and Tenant's name from the monument sign and returning
     the surface to which such signs were affixed to the condition they were
     in prior to such installation, including without limitation removal of
     any discoloration.

J.   INTERPRETATION

     This Addendum is attached to and forms a part of the Lease. In the event
     of any inconsistency between the provisions of this Addendum and the
     balance of the Lease, the provisions of this Addendum shall control.

                                       CONSTRUCTION WORK LETTER
                                           (Tenant Allowance)

In connection with the Lease to which this Work Letter is attached and in 
consideration of the mutual covenants hereinafter contained, Landlord and 
Tenant hereby agree as follows:

1.  BASE BUILDING.

    Landlord and Tenant understand and acknowledge that this Work Letter 
    Agreement relates only to "non-base building" work in the Premises. The 
    "base building work" has or will be performed by Landlord at Landlord's 
    sole cost and expense. The term "base building work" means and refers to 
    the following elements of the initial (i.e., first floor) Premises: 
    concrete floors (without above-standard floor covering, i.e., in a 
    condition such that Tenant is not required to perform above-standard 
    floor preparation (e.g., no excessive cracking, hazing or spalling), but 
    Landlord shall not be required, e.g., to remove existing standard 
    flooring, remove mastic or depress the floor for Tenant's finishes)), 
    perimeter walls in place (which may require wall repair, removal of 
    existing wall-covering, preparation of walls to receive covering and/or 
    utility device removal and/or installation by Tenant), existing 2x2 "fine 
    line" ceiling grid, including (on first floor (i.e., initial) Premises 
    only) existing 2x4 parabolic light fixtures (which may require 
    modification to conform with Tenant's plans), finished toilet rooms 
    upgraded (if necessary) to conform to current California Handicap and ADA 
    code compliance, closets for telephone and electrical systems (but not 
    the systems themselves) and building systems as follows: elevator system 
    upgraded (if necessary) to conform to current California Handicap and ADA 
    code compliance, mechanical (including heating, ventilating and 
    air-conditioning systems, which may require modification by Tenant to 
    conform with Tenant's distribution plan), electrical and plumbing 
    systems, all within the Building core only.

    The "base building work" shall also include the building exterior, 
    grounds and parking lot (including striping and accessibility relative to 
    California Handicap law and ADA code compliance), corridors connecting 
    the new building lobby; (see Section 4 as it pertains to the new building 
    lobby), to exits as required by code and to the elevator vestibules (but 
    not exterior doors for the Premises, and excluding the cost of the 
    interior half of all walls, i.e., corridor walls and demising walls, 
    which adjoin the Premises).

    Notwithstanding anything to the contrary herein, any changes in existing 
    improvements required to be performed above the drop-ceiling within the 
    Premises and/or below the roof of the Building shall not be included in 
    "base building work;" provided, however, that "base building work" shall 
    include any repair required to be performed to existing HVAC equipment on 
    the roof of the Building to render the same operable (i.e., to ensure 
    there is out-take and in-take capacity).

2.  SPACE PLANS AND GENERAL SPECIFICATIONS.

    a.  The tenant improvements in the Premises consist of two components: 
        (i) improvements to the data center portion of the Premises, which is 
        located approximately as indicated on EXHIBIT B hereto (the "Data 
        Center") and (ii) improvements to the balance of the Premises 
        ("Landlord's Work" and, collectively with the Data Center 
        improvements, the "Tenant Improvements"). Tenant shall be solely 
        responsible, subject to Landlord's approval of the plans therefor, to 
        coordinate with Landlord's construction manager, ARES, Inc. ("ARES"), 
        in connection therewith and to Section 4.f. below, for all work to be 
        performed in the Data Center, both as to payment and performance. 
        Landlord


                                    EXHIBIT C,
                                    ---------
                                     Page 1

<PAGE>

        shall be responsible to perform Landlord's Work and, subject to 
        Section 4.e. below, for payment of costs incurred in connection 
        therewith.

    b.  Upon execution of the Lease, Tenant shall (i) authorize Wirt Design 
        Group ("ELN Spaceplanner") to coordinate the development of space 
        plans for the tenant improvements with ARES and Compel Corporation 
        ("Tenant's Contractor") and (ii) authorize Tenant's Contractor to 
        construct the improvements for the Data Center (the "Data Center 
        Improvements") on a design/build basis for Tenant. ELN Spaceplanner 
        will work with MEP and structural engineers selected or approved by 
        Landlord to assure complete coordination of Landlord's Work and the 
        Data Center.

    c.  Upon execution of the Lease, ARES shall republish the Work Schedule 
        attached hereto as EXHIBIT C-1 (which schedule is hereby approved by 
        Landlord and Tenant in all respects, including as to sequence, 
        resources, phasing and duration of tasks), inserting the date of 
        mutual execution and delivery of the Lease and the balance of the 
        dates based on the time periods specified therein, and shall 
        distribute the Work Schedule, as so revised, to Tenant. Upon 
        execution of the Lease, ARES and Tenant's Contractor shall together 
        develop a complete list of subcontractors for review by Tenant and 
        ELN Spaceplanner and their respective engineers and consultants. The 
        final subcontractor list approved by both Landlord and Tenant in 
        writing will designate those subcontractors who may be requested to 
        perform the Tenant Improvements.

    d.  Tenant shall cause ELN Spaceplanner to prepare space plans for the 
        Tenant Improvements for submission to Landlord for Landlord's 
        approval on or before the date specified therefor on the Work 
        Schedule, which space plans, together with general descriptions of 
        construction techniques, materials and finishes proposed for 
        Landlord's Work, for the Data Center and for the common lobby on the 
        first floor of the Building described in Section 4.b. below, shall be 
        delivered to Landlord for review and approval. Landlord shall approve 
        or disapprove said plans, in writing, within three (3) days of receipt 
        thereof as reflected on the Work Schedule. If Landlord timely 
        notifies Tenant of any disapproval of the space plans, Landlord's 
        notice of disapproval shall also set forth its reasons for 
        disapproval and suggested revisions to the space plans in order to 
        satisfy Landlord's concerns. Once the space plans have been approved 
        by both Landlord and Tenant (as so approved, the "Space Plans"), 
        Landlord shall develop from the Space Plans, within five (5) days 
        after final approval of the Space Plans and delivery to Landlord of 
        final Space Plans, a detailed "line-item" cost budget for Landlord's 
        Work which shall be presented to ELN Spaceplanner and Tenant for 
        review in budgeting.

3.  CONSTRUCTION DRAWINGS AND DETAILED SPECIFICATIONS.

    a.  Upon approval of the Space Plans by Landlord and Tenant and Tenant's 
        approval of the budget for Landlord's Work, ELN Spaceplanner, 
        together with the MEP and structural engineers approved by Landlord, 
        will develop working drawings for Landlord's Work and for the Data 
        Center. After approval by Tenant, the working drawings shall be 
        submitted to Landlord for review and approval. Landlord shall approve 
        or disapprove said drawings, in writing, within three (3) days of 
        receipt thereof as reflected on the Work Schedule.

    b.  After approval by Landlord and Tenant of the working drawings for the 
        Tenant Improvements (as so approved, the "Working Drawings"), ELN 
        Spaceplanner shall submit the drawings to the appropriate 
        governmental body for plan checking and building permitting.

                                       EXHIBIT C,
                                       ---------
                                        Page 2



<PAGE>

    c.  After review by governmental authorities, ELN Spaceplanner, together 
        with Landlord and Tenant, shall cause to be made any change in the 
        Working Drawings necessary to obtain the building permit.

    d.  The final set of Working Drawings prepared by ELN Spaceplanner will 
        be issued to Tenant's Contractor and ARES concurrently to assure that 
        the scheduling and execution of the Tenant Improvements are 
        completely coordinated.

    e.  After final approval of the Working Drawings, subject to Section 4.c. 
        above, no further changes thereto may be made without the prior 
        written approval of both Landlord and Tenant, and then only after 
        agreement by Tenant to pay any excess costs resulting from such 
        changes. Futhermore, Tenant shall be liable for any delays in 
        completing the Tenant Improvements, if any, resulting from such 
        changes. See "Over Tenant Allowance Payment Schedule", Section 6.

4.  COST OF TENANT IMPROVEMENTS.

    a.  Landlord shall pay the cost of the Tenant Improvements to be made 
        pursuant to the Space Plans, up to a total amount (inclusive of all 
        architectural, engineering, space planning, construction management, 
        permitting and other fees of Landlord in connection therewith) of 
        $25.00 per square foot of Rentable Area (one million three hundred 
        seventy-five and 00/100 dollars ($1,375,000.00); the "Tenant 
        Allowance"). Tenant shall be responsible for any excess of the costs 
        of Landlord's Work over the Tenant Allowance and, subject to Section 
        4.f. below, for the cost of the Data Center Improvements.

    b.  Costs incurred by Landlord in constructing the new common area lobby 
        on the first floor of the Building shall be Landlord's responsibility 
        and shall not be reimbursed to Landlord from the Tenant Allowance.

    c.  Costs incurred by Landlord in delivery of utilities to the existing 
        equipment in the equipment room for the Building from which such 
        systems are distributed to tenant(s) of the Building shall be 
        Landlord's responsibility and shall not be reimbursed to Landlord 
        from the Tenant Allowance.

    d.  In the event that the estimated costs of the Tenant Improvements 
        exceed the Tenant Allowance, Landlord shall so notify Tenant, 
        submitting such estimate and Landlord's calculation of the excess. 
        Tenant shall approve or disapprove the estimate in writing within 
        seven (7) days of receipt of the same. Any notice of disapproval 
        shall specify the reasons therefor. Tenant's failure to respond, in 
        writing, to the estimate within such seven (7) day period shall be 
        deemed approval of the estimate. If Tenant shall fail to approve any 
        estimate in full within such seven (7) day period, Tenant shall be 
        deemed to have disapproved the estimate, and Landlord shall not 
        proceed with any Landlord's Work affected thereby. Landlord and 
        Tenant shall thereafter cooperate to amend the plans and 
        specifications for the Premises as necessary to obtain Tenant's approval
        of the cost of the Tenant Improvements; provided, however, that 
        Tenant shall pay any costs resulting from such amendments and Tenant 
        shall be liable for the delay in completing the Tenant Improvements 
        and the increased costs in completing the affected Tenant 
        Improvements, if any, in excess of the Tenant Allowance resulting 
        from such delay. In addition, the cost of the changes requested by 
        Tenant which are to be paid by Tenant as set forth herein shall 
        include the contractor's charges and the construction management fee 
        based on the total cost of construction of any additional Landlord's 
        Work in excess of the Tenant Allowance. If Tenant approves any such 
        estimate, it shall pay Landlord the amount of such estimate on 
        account of Landlord's Work on a prorated basis as set forth in 
        "Over Tenant Allowance Payment Schedule", Section 6.

                                      EXHIBIT C,
                                      ----------
                                       Page 3

<PAGE>

    e.  Landlord may credit against the Tenant Allowance (i.e., reduce the 
        outstanding balance of the Tenant Allowance by) all costs incurred by 
        Landlord in connection with the Tenant Improvements (excluding fees 
        of engineers, space planners or architects hired by Landlord); permit 
        fees; a construction management fee of five percent (5%) based on the 
        total cost of Landlord's Work (which will be paid to an affiliate of 
        Landlord, ARES, for construction management services rendered by 
        ARES), profit and general conditions and other costs payable to 
        reimburse to ARES actual costs incurred by ARES in connection with 
        Landlord's Work and all hard construction costs.

    f.  In the event that there is any excess of the Tenant Allowance after 
        Landlord completely reconciles the cost of Landlord's Work and any 
        other costs permitted by Landlord to be applied against the Tenant 
        Allowance pursuant to Section 4.e. above, then Landlord shall so 
        notify Tenant, and Tenant may request Landlord to disburse the 
        balance of the Tenant Allowance to Tenant to cover actual, 
        out-of-pocket costs incurred by Tenant in connection with the Tenant 
        Improvements, including without limitation, costs of preparing the 
        Space Plans and Working Drawings; fees and reimbursable expenses of 
        professionals such as telephone/data consultants, mechanical, 
        electrical, plumbing and structural engineers, permit fees and all 
        hard construction costs including demountable full height walls and 
        systems furniture and exterior Building identification signage. 
        Disbursement of the balance, if any, of the Tenant Allowance pursuant 
        to this subsection f. (the "Excess Allowance") shall be made by 
        Landlord to Tenant upon Tenant's written request therefor and upon 
        the last to occur of the following: (A) submission by Tenant to 
        Landlord of a detailed list of improvements paid for with the Excess 
        Allowance, (B) submission by Tenant to Landlord of (i) a copy of a 
        Notice of Completion with respect to the Tenant's Work showing 
        thereon the recording stamp of the Los Angeles County Recorder, (ii) 
        evidence reasonably satisfactory to Landlord that all of Tenant's 
        Work has been paid in full and that no claim of any mechanic or 
        materialman may become a lien on the Premises and (iii) a copy of the 
        inspection card for Tenant's Work with all final signatures complete, 
        (C) completion of all punch-list items for Tenant's Work and (D) the 
        expiration (without filing of a claim) of the applicable period 
        within which a lien may be filed pursuant to California Civil Code 
        Section 3114 ET SEQ.; provided, however, that in no event shall 
        Landlord be required to pay the Excess Allowance or any portion 
        thereof until and unless Tenant is not then in default pursuant to 
        the Lease. Landlord shall be entitled to all tax benefits in 
        connection with the allowed costs covered by the Tenant Allowance, 
        including without limitation the Excess Allowance. Any application by 
        Tenant for payment of the Excess Allowance shall be accompanied by 
        documentary evidence reasonably satisfactory to Landlord as to the 
        amount so requested by Tenant (including without limitation a 
        detailed breakdown of any amount applied for on account of the 
        construction contract for the Data Center), and by conditional liens 
        executed by Tenant and its contractors or subcontractors in favor of 
        Landlord in the amount of the installment to be paid by Landlord with 
        respect to any permanent improvements covered thereby. As and when 
        progress payments are made by Tenant with respect to Tenant's Work, 
        Tenant shall obtain, from each person furnishing labor or material 
        with respect to Tenant's Work, unconditional waivers and releases of 
        lien claims in the forms required by California Civil Code Section 
        3262. All of Tenant's Work shall comply with all applicable 
        governmental requirements.

    g.  Upon completion by Landlord of Landlord's Work, Landlord shall 
        determine the actual final cost of the work for the Premises to be 
        paid for by Tenant in accordance with Section 4.d. above and shall 
        submit a written statement of such amount to Tenant. If the estimate 
        previously paid by Tenant for such work exceeds the actual cost of 
        such work, such excess shall be credited by Landlord against the next 
        rental coming due under the Lease. If the actual cost of such

                                      EXHIBIT C,
                                      ----------
                                       Page 4

<PAGE>

        work exceeds the estimate therefor previously paid by Tenant, then 
        Tenant shall pay such excess in full within ten (10) days of receipt 
        of Landlord's invoice therefor.

5.  OVER TENANT ALLOWANCE PAYMENT SCHEDULE.

    Upon completion of bidding, if the maximum Tenant Allowance is less than 
    the final approved cost of constructing Landlord's Work, Tenant shall have 
    the following options for payment and/or reduction in payment liabilities 
    to Landlord:

    a.  Should the budget for Landlord's Work exceed the Tenant Allowance, 
        Tenant shall pay Landlord the excess amount which is determined in 
        accordance with Section 4.d. above (the "Excess Costs") in four (4) 
        installments, as follows: thirty percent (30%) of the Excess Costs 
        shall be paid to Landlord by Tenant concurrently with Tenant's 
        approval of the estimate therefor in accordance with Section 4.d. 
        (which approval shall constitute Tenant's authorization to Landlord 
        to proceed with Landlord's Work); the second and third payments 
        (which shall each be equal to thirty percent (30%) of the Excess 
        Costs) shall be paid to Landlord by Tenant thirty (30) and sixty (60) 
        days, respectively, following the date Landlord commences 
        construction of Landlord's Work (which shall be conclusively 
        evidenced by Landlord's written notice to Tenant that such 
        construction has commenced); and the last payment of ten percent 
        (10%) of the Excess Costs shall be paid to Landlord by Tenant upon 
        completion by Landlord of the punchlist items for Landlord's Work in 
        accordance with Section III.D. of the Lease and ELN Spaceplanner's 
        "sign-off" to that effect.

    b.  If, during the course of construction, Tenant elects to modify the 
        scope of Landlord's Work, the subsequent increase or decrease in the 
        cost thereof shall be prorated over the balance of the payments to be 
        made by Landlord to Tenant pursuant to subsection a. above such that 
        the final payment is ten percent (10%) of the total Excess Costs, and 
        the balance of any such increase or decrease is spread evenly among the 
        other payments remaining to be made.

6.  CONSTRUCTION OF TENANT IMPROVEMENTS.

    a.  After the Working Drawings for the Tenant Improvements have been 
        approved by Tenant and Landlord and while the building department is 
        reviewing the plan submittals, ELN Spaceplanner shall coordinate with 
        the structural engineers to issue a complete set of construction 
        drawings for competitive bid.

    b.  Concurrently, Landlord shall cause its contractor, or 
        subcontractors, to complete the "base building" work required by the 
        Work Schedule to be completed prior to commencement of construction 
        of the Tenant Improvements.

    c.  All work, including the Tenant Improvements, shall be performed in 
        compliance with the ADA, the Space Plans and Working Drawings, and 
        shall be completed, subject to "Force Majeure" (as that term is 
        defined in Section XXXIII.K. of the Lease), on or before the 
        respective dates specified therefor on the Work Schedule. 
        Notwithstanding the foregoing, installation or construction of 
        Landlord's Work requested by Tenant after approval of the Space 
        Plans, or otherwise affected by any such request, shall not commence 
        until Tenant shall have approved the estimated cost thereof in 
        accordance with Section 4.d. above.

    d.  The construction of the Data Center shall not be included in 
        Landlord's Work and shall be performed by Tenant's Contractor under 
        separate contract with Tenant. Landlord shall have the right to 
        approve the contractor for the Data Center Improvements, and the form 
        of the contract Tenant proposes to use, which

                                     EXHIBIT C,
                                     ----------
                                      Page 5

<PAGE>

        contract shall meet the requirements of Section XII. of the Lease and 
        shall contain a waiver, executed by the contractor on behalf of its 
        and all subcontractors and in favor of Landlord, specifically waiving 
        any and all rights to recover any amount from Landlord on account of 
        the performance of the Data Center Improvements and waiving all lien 
        rights with respect to Landlord's interest in the Premises, Building 
        and Project. It shall be Tenant's sole responsibility, in a timely 
        manner and (subject to Section 4.f. above) at Tenant's sole cost and 
        expense, to perform all work necessary to completely segregate the 
        Data Center from the balance of the Premises (which work shall be 
        considered a Data Center Improvement) on or before December 19, 1996, 
        including without limitation to relocate any utilities serving the 
        balance of the Premises from the Data Center, such that the Data 
        Center is completely self-sufficient and separate from the balance of 
        the Premises and such that Tenant Improvements can be constructed 
        concurrently in the Data Center, by Tenant, and in the balance of the 
        Premises, by Landlord, without any interference and/or 
        interdependency in connection therewith.

7.  COMPLETION AND LEASE COMMENCEMENT DATE.

    If the Lease Commencement Date of the Lease, as determined under Sections 
    I.G. and III.C., is delayed by any of the following, then the Lease 
    Commencement Date of the Lease and the payment of rent shall be 
    accelerated (i.e., moved earlier in time) by the number of days of such 
    delay:

    a.  Tenant's failure to approve or furnish Space Plans or Working 
        Drawings or failure to approve any other item (including without 
        limitation estimates) or perform any other obligation in accordance 
        with and by the dates specified herein or in the Work Schedule.

    b.  Any delays caused by ELN Spaceplanner and/or Tenant's Contractor; 
        provided, however, that any delays prior to December 19, 1996 that do 
        not delay Tenant's ability to obtain all permits necessary to enable 
        Landlord to commence Landlord's Work in the Premises on December 19, 
        1996 in the condition specified in the last sentence of Section 6.d. 
        above and do not otherwise affect Landlord's ability to perform its 
        work in the Premises thereafter shall not accelerate the Lease 
        Commencement Date.

    c.  Delays of any nature resulting from Tenant's decision to use any 
        materials, finishes or installations other than Building standard 
        materials.

    d.  Tenant's changes in the Space Plans, Working Drawings or other plans 
        and specifications after the approval thereof by Tenant.

    e.  Delays in construction of the base building work, Landlord's Work 
        and/or the Data Center Improvements as a result of Tenant's failure 
        to approve written estimates in accordance with Section 4.

    f.  Delays in Tenant obtaining any necessary governmental approvals or 
        permits for Tenant's intended use of the Premises.

8.  FURNITURE AND TELEPHONE SYSTEM.

    Subject to Section 4.f. above, Tenant acknowledges and agrees that Tenant 
    is solely responsible, both as to performance and payment of costs, for 
    "Tenant's Work", which includes designing and constructing the Data 
    Center as provided above, obtaining, delivering and installing on the 
    Premises all necessary or desired telephone equipment, telephone cabling, 
    telephone service, business equipment, freestanding furniture, art work

                                        EXHIBIT C,
                                        ----------
                                         Page 6

<PAGE>

    and other similar items, and that Landlord shall have no responsibility 
    whatsoever with regard thereto. Tenant further acknowledges and agrees 
    that neither the Lease Commencement Date of the Lease nor the payment of 
    rent shall be delayed for any period of time whatsoever due to any delay 
    in the furnishing of the Premises with such items. Installation of all 
    telephone, computer and other electronic wires and cables within the 
    Premises and within the common ducts and shafts of the Building is 
    subject to Landlord's prior approval and shall be performed in accordance 
    with Landlord's reasonable rules and regulations.

9.  FAILURE OF TENANT TO COMPLY.

    Any failure of Tenant to comply with any of the provisions contained in 
    this EXHIBIT C, within the times for compliance set forth herein or in 
    the Work Schedule, shall be deemed a default pursuant to the Lease. In 
    addition to the remedies provided to Landlord in this EXHIBIT C, upon the 
    occurrence of such a default by Tenant, Landlord shall have all remedies 
    available at law or equity to a landlord against a defaulting tenant 
    pursuant to a written lease, including but not limited to those set forth 
    in Section XX. DEFAULT and Section XXIV. ATTORNEYS' FEES of the Lease.

10. AUTHORIZED APPROVALS.

    All approvals required pursuant to the terms of this Work Letter or 
    requests for changes and modifications to the Space Plans, Working 
    Drawings or any other matter relating to the construction of the Tenant 
    Improvements shall be deemed given for Tenant if approved or requested in 
    writing by Ken Washburn, Tenant's Construction Representative, and for 
    Landlord if approved or requested in writing by John Monahan, Landlord's 
    Construction Representative.

11. DESTRUCTION.

    If at any time prior to the completion of the Tenant Improvements a 
    casualty occurs resulting in any damage or destruction of the partially 
    completed Tenant Improvements or the Premises or Building, the terms and 
    conditions of Section XVIII. DAMAGE AND DESTRUCTION of the Lease shall 
    govern the rights and obligations of the parties.

The term "Rentable Area" as used in the Lease shall be determined in 
accordance with BOMA standards. For purposes of establishing the Monthly 
Rental, the Rentable Area of the Premises is deemed to be as set forth in 
Section 1.E. above, and the Rentable Area of the Building is deemed to be 
110,419 square feet. Prior to the Lease Commencement Date, and from time to 
time thereafter at Landlord's option, Landlord's architect shall determine 
and certify in writing to Tenant and Landlord the actual Rentable Area of the 
Premises and the Building, respectively, in accordance with the foregoing. 
Within five (5) days after receipt of Landlord's architect's calculation of 
the Rentable Area of the Premises, Building and/or Project, Tenant may, by 
written notice, protest Landlord's architect's determination. Landlord will 
provide to Tenant's architect reasonable back-up for its measurement of the 
areas objected to. In the event that, upon reviewing the back-up so provided 
by Landlord, Tenant disagrees with the measurements by Landlord's architect, 
Tenant may so notify Landlord. If Landlord agrees with the findings of 
Tenant, then an appropriate adjustment shall be made. In the event that there 
is a disagreement, then Landlord's architect and Tenant's architect shall 
select an architect who is an AIA member, who shall determine the Rentable 
Area(s) in dispute, which determination shall be binding upon Landlord and 
Tenant. Thereupon the Monthly Rental, Tenant's Proportionate Share, the 
Tenant Allowance and the Security Deposit shall be adjusted accordingly. 
Tenant shall, within ten (10) days after such determination, deliver to 
Landlord any additional Monthly Rental due as a result of such adjustment and 
shall deposit with Landlord, as an additional cash Security deposit, and 
amount equal to the increase, if any, in the Security Deposit effected 
thereby. If, as a result of such remeasurement, the Rentable Area is 
decreased, Landlord shall apply any overpayment of Monthly Rental against the 
next Monthly Rental coming due hereunder.

                                 EXHIBIT E

                          RULES AND REGULATIONS

                 ATTACHED TO AND MADE A PART OF THE LEASE

The following Rules and Regulations shall be in effect at the Building. 
Landlord reserves the right to adopt reasonable modifications and additions 
hereto. In the case of any conflict between these regulations and the Lease, 
the Lease shall be controlling. Landlord shall have the right to waive one or 
more rules for the benefit of a particular tenant in Landlord's reasonable 
discretion.

1.      Except with the prior written consent of Landlord, no tenant shall 
        conduct any retail sales (other than electronic or mail order sales) 
        in or from the Premises, or any business other than that specifically 
        provided for in the Lease. The foregoing shall not apply to sales of 
        internet services, to incidental, occasional sales of promotional 
        retail products associated with Tenant's business to invitees of 
        Tenant whose presence at the Premises is not for the primary purpose 
        of purchasing promotional retail products associated with Tenant's 
        business to employees of Tenant at the Premises. There shall be no 
        solicitation by Tenant of other tenants or occupants of the Building.

2.      Landlord reserves the right to prohibit personal goods and services 
        vendors from access to the Building except upon such reasonable terms 
        and conditions, including but not limited to a provision for 
        insurance coverage, as are related to the safety, care and 
        cleanliness of the Building, the preservation of good order thereon, 
        and the relief of any financial or other burden on Landlord 
        occasioned by the presence of such vendors or the sale by them of 
        personal goods or services to a tenant or its employees. If 
        reasonably necessary for the accomplishment of these purposes, 
        Landlord may exclude a particular vendor entirely or limit the number 
        of vendors who may be present at any one time in the Building. The 
        term "personal goods or services vendors" means persons who 
        periodically enter the Building of which the Premises are a part for 
        the purpose of selling goods or services to a tenant, other than 
        goods or services which are used by a tenant only for the purpose of 
        conducting its business on the Premises. "Personal goods or services" 
        include, but are not limited to, drinking water and other beverages, 
        food, barbering services, and shoeshining services.

3.      The sidewalks, halls, passages, elevators and stairways shall not be 
        obstructed by any tenant or used by it for any purpose other than for 
        ingress to and egress from their respective Premises. The halls, 
        passages, entrances, elevators, stairways, balconies, janitorial 
        closets, and roof are not for the use of the general public, and 
        Landlord shall in all cases retain the right to control and prevent 
        access thereto of all persons whose presence in the judgment of 
        Landlord shall be prejudicial to the safety, character, reputation 
        and interests of the Building and its tenants, provided that nothing 
        herein contained shall be construed to prevent such access to persons 
        with whom Tenant normally deals only for the purpose of conducting 
        its business on the Premises (such as clients, customers, office 
        suppliers and equipment vendors, and the like) unless such persons 
        are engaged in illegal activities. No tenant and no employees of any 
        tenant shall go upon the roof of the Building without the written 
        consent of the Landlord.

4.      The sashes, sash doors, windows, glass lights, and any lights or 
        skylights that reflect or admit light into the halls or other places 
        of the Building shall not be covered or obstructed. The toilet rooms, 
        water and wash closets and other water apparatus shall not be used 
        for any purpose other than that for which they were constructed, and 
        no foreign substance of any kind whatsoever shall be thrown therein, 
        and the expense of any


                                EXHIBIT E,
                                  Page 1

<PAGE>

        breakage, stoppage or damage, resulting from the violation of this rule
        shall be borne by the tenant who, or whose clerks, agents, employees, or
        visitors, shall have caused it.

5.      No sign, advertisement or notice visible from the exterior of the 
        Premises or Building shall be inscribed, painted or affixed by Tenant 
        on any part of the Building or the Premises without the prior written 
        consent of Landlord. If Landlord shall have given such consent at any 
        time, whether before or after the execution of this Lease, such 
        consent shall in no way operate as a waiver or release of any of the 
        provisions hereof or of this Lease, and shall be deemed to relate 
        only to the particular sign, advertisement or notice so consented to 
        by Landlord and shall not be construed as dispensing with the 
        necessity of obtaining the specific written consent of Landlord with 
        respect to each and every such sign, advertisement or notice other 
        than the particular sign, advertisement or notice, as the case may 
        be, so consented to by Landlord.

6.      In order to maintain the outward professional appearance of the 
        Building, all window coverings to be installed at the Premises shall 
        be subject to Landlord's prior reasonable approval. If Landlord, by a
        notice in writing to Tenant, shall object to any curtain, blind, 
        shade or screen attached to, or hung in, or used in connection with, 
        any window or door of the Premises, such use of such curtain, blind, 
        shade or screen shall be forthwith discontinued by Tenant. No awnings 
        shall be permitted on any part of the Premises.

7.      Tenant shall not do or permit anything to be done in the Premises, or 
        bring or keep anything therein, which shall in any way increase the 
        rate of fire insurance on the Building, or on the property kept 
        therein, or obstruct or interfere with the rights of other tenants, 
        or in any way injure or annoy them; or conflict with the regulations 
        of the Fire Department or the fire laws, or with any insurance policy 
        upon the Building, or any part thereof, or with any rules and 
        ordinances established by the Board of Health or other governmental 
        authority. Tenant shall not bring into, or permit or suffer in, the 
        Building or the Project, any weapons or firearms of any kind. 
        Landlord shall have the right, in order to conduct such fire drills 
        as may be required by applicable governmental authorities and/or 
        insurance requirements, and in all other situations where Landlord 
        reasonably deems the same necessary to avoid property damage and/or 
        personal injury, to cause tenants and/or occupants of the Project to 
        vacate the same for such period as is required or reasonably 
        necessary, and Tenant shall cause its employees, agents, contractors 
        and invitees to cooperate in connection therewith.

8.      No safes or other objects larger or heavier than the freight 
        elevators of the Building are limited to carry shall be brought into 
        or installed in the Premises. Landlord shall have the power to 
        prescribe the weight, method of installation and position of such 
        safes or other objects. The moving of safes shall occur only between 
        such hours as may be designated by, and only upon previous notice to, 
        the manager of the Building, and the persons employed to move safes 
        in or out of the Building must be acceptable to Landlord. No freight, 
        furniture or bulky matter of any description shall be received into 
        the Building or carried into the elevators except during hours and in 
        a manner approved by Landlord.

9.      Except as provided in the Lease, Landlord shall clean the Premises as 
        provided in the Lease, and except with the written consent of 
        Landlord, no person or persons other than those approved by Landlord 
        will be permitted to enter the Building for such purpose, but Tenant 
        shall not cause unnecessary labor by reason of Tenant's carelessness 
        and indifference in the preservation of good order and cleanliness.

10.     No tenant shall sweep or throw or permit to be swept or thrown from 
        the Premises any dirt or other substance into any of the corridors or 
        halls or elevators, or out of the doors or windows or stairways of 
        the Building, and Tenant shall not use, keep or permit to be used or 
        kept any foul or noxious gas or substance in the Premises, or permit 
        or suffer

                                EXHIBIT E,

        the Premises to be occupied or used in a manner offensive 
        or objectionable to Landlord or other occupants of the Building by 
        reason of noise, odors and/or vibrations, or interfere in any way 
        with other tenants or those having business therein, nor shall any 
        animals, firearms or birds be kept in or about the Building. The 
        Building is a non-smoking building. Smoking or carrying lighted 
        cigars or cigarettes in any buildings located in the Project, 
        including the Building and the elevators of the Building, is 
        prohibited.

11.     Except for the use of microwave ovens and coffee makers for Tenant's 
        personal use, no cooking shall be done or permitted by Tenant on the 
        Premises, nor shall the Building be used for lodging.

12.     Tenant shall not use or keep in the Building any kerosene, gasoline, 
        or inflammable fluid or any other illuminating material, or use any 
        method of heating other than that supplied by Landlord.

13.     Unless Tenant occupies the entire Building, if Tenant desires 
        telephone connections, Landlord will direct electricians as to where 
        and how the wires are to be introduced. Unless Tenant occupies the 
        entire Building, no boring or cutting for wires or other otherwise 
        shall be made without directions from Landlord.

14.     Each tenant, upon the termination of its tenancy, shall deliver to 
        Landlord all the keys of offices, rooms and toilet rooms, and 
        security access card/keys which shall have been furnished such tenant

                 (_____________________ / Loan No. ___________)


NOTICE; THE SUBORDINATION PROVIDED FOR IN THIS AGREEMENT RESULTS IN YOUR 
LEASEHOLD ESTATE IN THE PROPERTY BECOMING SUBJECT TO AND OF LOWER PRIORITY

THIS SUBORDINATION, NONDISTURBANCE AND ATTORNMENT AGREEMENT (the "Agreement") 
is made this ____ day of ___________________, 19__, by and between ___________
____________________, a ______________________ ("Lessor"), and _______________

                             --------------------

WHEREAS, Lessor has entered into or is about to execute a Deed of Trust, 
Assignment of Rents, Security Agreement and Fixture Filing in favor of
Beneficiary and naming therein __________________________, Trustee (the "Deed 
of Trust"), covering certain real property (the "Property") located in the

WHEREAS, Lessor and Lessee have entered into a lease dated as of 
_______________, 19__ (the "Lease"), covering a portion of the building located 
on the Property, for the term and upon the terms and conditions therein set 
forth; and,

WHEREAS, for the purpose of completing the loan financing to be provided to 
Lessor by Beneficiary with respect to the Property and improvements thereon, 
the parties hereto desire to expressly subordinate the Lease and all rights 
and interests of Lessee thereunder to the lien of the Deed of Trust (as the 
same may hereafter be amended), it being a condition precedent to the 
consummation of said loan financing that the lien of the Deed of Trust be 
unconditionally and at all times prior and superior to the leasehold 
interests and estates created by the Lease; and,

WHEREAS, it is to the mutual benefit of all of the parties hereto that 
Beneficiary make said loan to Lessor.

NOW, THEREFORE, in consideration of the foregoing and other good and valuable 
consideration, the receipt and sufficiency of which are hereby acknowledged, 
and of the mutual benefits to accrue to the parties hereto, and in order to 
induce Beneficiary to make the loan hereinabove referred to, it is hereby 
declared, understood and agreed as follows:

     1.  Lessor and Lessee declare and acknowledge that each hereby 
         intentionally waives, relinquishes and subordinates the priority and 
         superiority of the Lease, the leasehold interests and estates 
         created thereby, and the rights, privileges and powers of the Lessee
         and Lessor thereunder, including without limitation any purchase
         options, rights of first refusal, rights to any condemnation awards
         and similar rights or interests of the Lessee under said Lease, in
         favor of the Deed of Trust (and any and all modifications of the 
         same or replacements therefor entered into after the date hereof), 
         and that each understands that in reliance upon, and in consideration 
         of, this waiver, relinquishment and subordination, Beneficiary is 
         making the loan referred to hereinabove, which would not be made but in
         said reliance upon, and in consideration of, this waiver, 
         relinquishment and subordination.

     2.  It is expressly understood and agreed that this Agreement and the 
         Deed of Trust shall supersede, the provisions of the Lease, to the
         extent that the same are inconsistent with this Agreement or the Deed
         of Trust (as later modified, amended or replaced).

     3.  In the event Beneficiary or any other purchaser at a foreclosure 
         sale or sale under private power contained in the Deed of Trust
         succeeds to the interest of Lessor in the Property by reason of any
         foreclosure of the Deed of Trust or the acceptance of a deed in lieu
         of foreclosure, or by any other manner, it is agreed that,
         notwithstanding the subordination of the Lease provided for
         hereinabove:

         a.  Lessee shall be bound to Beneficiary or such other purchaser 
             under all of the terms, covenants and conditions of the Lease
             for the remaining balance of the term thereof and any extensions
             thereof, with the same force and effect as if Beneficiary or such
             other purchaser were the original lessor under such Lease, and 
             Lessee does hereby agree to attorn to Beneficiary or such other
             purchaser as its lessor, such attornment to be effective and
             self-operative without the execution of any further instruments 
             on the part of any of the parties to this Agreement, immediately
             upon Beneficiary or such other purchaser succeeding to the interest
             of Lessor in the Property.

         b.  Subject to the observance and performance by Lessee of all of 
             the terms, covenants and conditions of the Lease on the part of the
             Lessee to be observed and performed, and provided that Lessee is
             then in possession of the leased premises, Beneficiary or such 
             other purchaser shall recognize the leasehold estate of Lessee
             under all of the terms, covenants and conditions of the Lease for
             the remaining balance of the term or extension thereof with the
             same force and effect as if Beneficiary or such other purchaser
             were the original lessor under the Lease; provided, however, that
             Beneficiary or such other purchaser shall not be (i) liable for any
             act or omission of any prior lessor (including Lessor), (ii)
             obligated to cure any defaults of any prior lessor (including
             Lessor) under the Lease which occurred prior to the time that
             Beneficiary or such other purchaser succeeded to the interest of
             Lessor in the Property, (iii) subject to any offsets or defenses 
             which Lessee may be entitled to assert against any prior lessor 
             (including Lessor), (iv) bound by any payment of rent or additional
             rent by Lessee to any prior lessor (including Lessor) for more than
             two (2) months in advance, (v) bound by any amendment or
             modification of the Lease made without the prior written consent of
             Beneficiary or such other purchaser, (vi) liable or responsible for
             or with

             by Beneficiary of the Deed of Trust in connection with which 
             Beneficiary or a third party acquires title to the Property, (B) to
             a sale of the Property to Beneficiary or a third party in lieu of

             of Trust with respect to insurance and condemnation proceeds
             relating to the Property.

     4.  Lessee hereby agrees that it will not exercise any right granted it 
         under the Lease, or which it might otherwise have under applicable law,
         to terminate the Lease or perform any obligations of Lessor under the
         Lease for Lessor's account because of a default of Lessor thereunder or
         the occurrence of any other event without first giving to 
         Beneficiary prior written notice of Lessee's intent so to terminate 
         or perform, which notice shall include a statement of the default or
         event on which such intent to terminate or perform is based.
         Thereafter, Lessee shall not take any action to terminate the Lease or
         so perform if Beneficiary: (i) within sixty (60) days after service of
         such written notice on Beneficiary by Lessee of its intention so to
         terminate the Lease or perform, shall cure such default or event, if
         the same can be cured by the payment or expenditure of money; or (ii)
         shall diligently take action to obtain possession of the leased
         premises (including possession by receiver and/or foreclosure) and to
         cure such default or event in the case of a default or event which
         cannot be cured unless and until the Beneficiary has obtained
         possession.

     5.  Subject to paragraph 4 above, Lessor and Lessee hereby agree not to 
         terminate, modify or amend the Lease, or any of the terms thereof,
         without the prior written consent of Beneficiary, and further agree
         that any attempted termination, modification or amendment of the 
         Lease without prior written consent of Beneficiary shall be null and
         void.

     6.  For the purposes of facilitating Beneficiary's right hereunder, 
         Beneficiary shall have, and for such purposes is hereby granted by
         Lessee and Lessor, the right to enter upon the Property and any
         improvements thereon for the purpose of effecting any cure provided
         for herein and for the purpose of inspecting the Property and the
         improvements thereon and showing the same to prospective bidders and
         their agents and employees in connection with a pending judicial or
         non-judicial foreclosure sale.

     7.  Lessee hereby agrees to give to Beneficiary, concurrently with the 
         giving of any notice of any nature given by Lessee to the Lessor under
         the Lease, a copy of such notice by mailing the same to Beneficiary in
         the manner set forth hereinbelow, and no such notice given to the
         Lessor which is not at or about the same time also given to Beneficiary
         shall be valid or effective against Beneficiary for any purpose. Cure
         rights and other rights provided to Beneficiary herein shall run from
         the date of Beneficiary's receipt of such notice from Lessee (without
         regard to the date upon which Lessee delivers notice to Lessor).

         For purposes of any notices to be given to Beneficiary hereunder, 
         the same shall be sent by U.S. certified mail, return receipt
         requested, postage prepaid, to Beneficiary at the following address:

         [Address]

         or to such other address as Beneficiary may hereafter notify 
         Lessee in writing by notice sent to Lessee as aforesaid at Lessee's
         address at the Property, or such other address as Beneficiary may
         hereafter be advised of in writing by notice sent to Beneficiary as
         aforesaid.

     8.  The agreements contained herein shall run with the land and shall be 
         binding upon and inure to the benefit of the respective heirs, 
         administrators, executors, legal representatives, successors and
         assigns of the parties hereto.

     9.  Lessee, by the execution of this Agreement, acknowledges: (i) that 
         Lessor has collaterally assigned or is about to collaterally assign to 
         Beneficiary all of Lessor's right, title and interest in and to the
         Lease pursuant to an Assignment of Lessor's Interest (the
         "Assignment"); (ii) that under the terms of the Assignment, until the
         Note is paid in full, Lessor may not without the prior written consent
         of Beneficiary agree to any modification or termination of the Lease,
         accept the surrender of the Lease, collect any rent in advance of the
         due date specified in the Lease, collect any lease termination
         payments, exercise any right of election which would have an adverse
         effect upon the Lease or consent to any assignment or further
         subordination of Lessee's interest in the Lease; and (iii) that in the
         event of a default of any of the terms and conditions of the Note or
         any documents executed in connection therewith, Beneficiary has the
         right to collect the rental, lease termination and other payments due
         under the Lease in partial satisfaction of the Note. Unless and until
         Beneficiary notifies Lessee in writing of such a default (at which time
         all payments are to be made as the notice directs), all payments called
         for by the Lease are to be made as required by the Lease. Lessee
         acknowledges that the Lease has been assigned as security for the
         repayment of the Note only and no duty, liability, or obligation
         whatsoever under said Lease, solely by virtue of the Assignment, is
         assumed by Beneficiary.

    10.  Lessee shall, promptly upon written request of Beneficiary, execute, 
         cause to be acknowledged and deliver to Beneficiary any and all 
         documents which are required by Beneficiary to further carry out the 
         provisions of this Agreement, or the provisions of the Lease, including
         without limitation, execution, acknowledgement and delivery of a new 
         subordination, nondisturbance and attornment agreement, or a new lease,
         on the terms of such Lease, and as described herein, in the event this
         Agreement or the Lease, is deemed ineffective, following a foreclosure
         of the Deed of Trust, or an exercise of the power of sale thereunder,
         or for any other reason.

    11.  This Agreement may be executed in any number of counterparts, each 
         of which shall be deemed an original, and all such counterparts taken 
         together shall be deemed to constitute one and the same instrument.

         and prior and other writings with respect to its subject matter; and

any reason Lessor cannot deliver possession of the Premises to Lessee on said 
date and subject to paragraph 3.2.2, Lessor shall not be subject to any 
liability therefor, nor shall such failure affect the validity of this Lease

obligation of Lessee under the terms of this Lease, except as may be 
otherwise provided in this Lease, until possession of the Premises is 
tendered to Lessee, as hereinafter defined: provided, however, that if Lessor

option, by notice in writing to Lessor within ten (10) days thereafter, 
cancel this Lease, in which event the parties shall be discharged from all 
obligations hereunder: provided, however, that, as to Lessee's obligations, 
Lessee first reimburses Lessor for all costs incurred for Non-Standard 
Improvements and, as to Lessor's obligations, Lessor shall return any money 
previously deposited by Lessee (less any offsets due Lessor for Non-Standard 
Improvements): and provided further, that if such written notice by Lessee is 
not received by Lessor within said ten (10) day period, Lessee's right to 
cancel this Lease hereunder shall terminate and be of no further force or 
effect.

        3.2.1 POSSESSION TENDERED--DEFINED. Possession of the Premises shall 
be deemed tendered to Lessee ("Tender of Possession") when (1) the 
improvements to be provided by Lessor under this Lease are substantially 
completed, (2) the Building utilities are ready for use in the Premises, (3) 
Lessee has reasonable access to the Premises, and (4) ten (10) days shall 
have expired following advance written notice to Lessee of the occurrence of 
the matters described in (1), (2) and (3), above of this paragraph 3.2.1.

        3.2.2 DELAYS CAUSE BY LESSEE. There shall be no abatement of rent, 
and the sixty (60) day period following the Commencement Date before which 
Lessee's right to cancel this lease accrues under paragraph 3.2, shall be 
deemed extended to the extent of any delays caused by acts or omissions of 
Lessee, Lessee's agents, employees and contractors.

   3.3  EARLY POSSESSION. If Lessee occupies the Premises prior to said 
Commencement Date, such occupancy shall be subject to all provisions of this 
Lease, such occupancy shall not change the termination date, and Lessee shall 
pay rent for such occupancy.

   3.4  UNCERTAIN COMMENCEMENT. In the event commencement of the Lease term is 
defined as the completion of the improvements, Lessee and Lessor shall 
execute an amendment to this Lease establishing the date of Tender of 
Possession (as defined in paragraph 3.2.1) or the actual taking of possession 
by Lessee, whichever first occurs, as the Commencement Date.

4. RENT.

   4.1  BASE RENT. Subject to adjustment as hereinafter provided in paragraph 
4.3, and except as may be otherwise expressly provided in this Lease, Lessee 
shall pay to Lessor the Base Rent for the Premises set forth in paragraph 1.6 
of the Base Lease Provisions, without offset or deduction. Lessee shall pay 
Lessor upon execution hereof the advance Base Rent described in paragraph 1.8 
of the Basic Lease Provisions. Rent for any period during the term hereof 
which is for less than one month shall be prorated based upon the actual 
number of days of the calendar month involved. Rent shall be payable in 
lawful money of the United States to Lessor at the address stated herein or 
to such other persons or at such other places as Lessor may designate in 
writing.

   4.2  OPERATING EXPENSE INCREASE. Lessee shall pay to Lessor during the 
term hereof, in addition to the Base Rent, Lessee's Share, as hereinafter 
defined, of the amount by which all Operating Expenses, as hereinafter 
defined, for each Comparison Year exceeds the amount of all Operating 
Expenses for the Base Year, such excess being hereinafter referred to as the 
"Operating Expense Increase," in accordance with the following provisions:

        (a) "Lessee's Share" is defined, for purposes of this lease, as the 
percentage set forth in paragraph 1.10 of the Basic Lease Provisions, which 
percentage has been determined by dividing the approximate square footage of 
the Premises by the total approximate square footage of the rentable space 
contained in the Office Building Project. It is understood and agreed that the 
square footage figures set forth in the Basic Lease Provisions are 
approximations which Lessor and Lessee agree are reasonable and shall not be 
subject to revision except in connection with an actual change in the size of 
the Premises or a change in the space available for lease in the Office 
Building Project.

        (b) "Base Year" is defined as the calendar year in which the Lease 
term commences. Base year is 1996.

        (c) "Comparison Year" is defined as each calendar year during the 
term of this Lease subsequent to the Base Year; provided, however Lessee 
shall have no obligation to pay a share of the Operating Expense Increase 
applicable to the first twelve (12) months of the Lease Term (other than such 
as are mandated by a governmental authority, as to which government mandated 
expenses Lessee shall pay Lessee's Share, notwithstanding they occur during 
the first twelve (12) months). Lessee's Share of the Operating Expense 
Increase for the first and last Comparison Years of the Lease Term shall be 
prorated according to that portion of such Comparison Year as to which Lessee 
is responsible for a share of such increase.

        (d) "Operating Expenses" is defined, for purposes of this Lease, to 
include all costs, if any, incurred by Lessor in the exercise of its 
reasonable discretion, for:

            (i) The operation, repair, maintenance, and replacement, in neat, 
clean, safe, good order and condition, of the Office Building Project, 
including but not limited to, the following:

                (aa) The Common Areas, including their surfaces, coverings, 
decorative items, carpets, drapes and window coverings, and including parking 
areas, loading and unloading areas, trash areas, roadways, sidewalks, 
walkways, stairways, parkways, driveways, landscaped areas, striping, 
bumpers, irrigation systems, Common Area lighting facilities, building 
exteriors and roofs, fences and gates;

                (bb) All heating, air conditioning, plumbing, electrical 
systems, life safety equipment, telecommunication and other equipment used in 
common by, or for the benefit of, lessees or occupants of the Office Building 
Project, including elevators and escalators, tenant directories, fire 
detection systems including sprinkler system maintenance and repair.

           (ii) Trash disposal, janitorial and security services;

          (iii) Any other service to be provided by Lessor that is elsewhere 
in this Lease stated to be an "Operating Expense";

           (iv) The cost of the premiums for the liability and property 
insurance policies to be maintained by Lessor under paragraph 8 hereof;

            (v) The amount of the real property taxes to be paid by Lessor 
under paragraph 10.1 hereof;

           (vi) The cost of water, sewer, gas, electricity, and other 
publicly mandated services to the Office Building Project;

          (vii) Labor, salaries and applicable fringe benefits and costs, 
materials, supplies and tools, used in maintaining and/or cleaning the Office 
Building Project and accounting and a management fee attributable to the 
operation of the Office Building Project;

         (viii) Replacing and/or adding improvements mandated by any 
governmental agency and any repairs or removals necessitated thereby 
amortized over its useful life according to Federal income tax regulations or 
guidelines for depreciation thereof (including interest on the unamortized 
balance as is then reasonable in the judgment of Lessor's accountants);

          (ix) Replacements of equipment or improvements that have a useful 
life for depreciation purposes according to Federal income tax guidelines of 
five (5) years or less, as amortized over such life.

        (e) Operating Expenses shall not include the costs of replacements of 
equipment or improvements that have a useful life for Federal income tax 
purposes in excess of five (5) years unless it is of the type described in 
paragraph 4.2(d)(viii) in which case their cost shall be included as above 
provided.

        (f) Operating Expenses shall not include any expenses paid by any 
lessee directly to third parties, or as to which Lessor is otherwise 
reimbursed by any third party, other tenant, or by insurance proceeds.

        (g) Lessee's Share of Operating Expense increase shall be payable by 
Lessee within ten (10) days after a reasonably detailed statement of actual 
expenses is presented to Lessee by Lessor. At Lessor's option, however, an 
amount may be estimated by Lessor from time to time in advance of Lessee's 
Share of the Operating Expense Increase for any Comparison Year, and the same 
shall be payable monthly or quarterly, as Lessor shall designate, during each 
Comparison Year of the Lease term, on the same day as the Base Rent is due 
hereunder. In the event that the Lessee pays Lessor's estimate of Lessee's 
Share of Operating Expense Increase as aforesaid, Lessor shall deliver to 
Lessee within sixty (60) days after the expiration of each Comparison Year a 
reasonably detailed statement showing Lessee's Share of the actual Operating 
Expense Increase incurred during such year. If Lessee's payments under this 
paragraph 4.2(g) during said Comparison Year exceed Lessee's Share as 
indicated on said statement, Lessee shall be entitled to credit the amount of 
such overpayment against Lessee's Share of Operating Expense increase next 
falling due. If Lessee's payments under this paragraph during said Comparison 
Year were less than Lessee's Share as indicated on said statement, Lessee 
shall pay to Lessor the amount of the deficiency within ten (10) days after 
delivery by Lessor to Lessee of said statement. Lessor and Lessee shall 
forthwith adjust between them by cash payment any balance determined to exist 
with respect to that portion of the last Comparison Year for which Lessee is 
responsible as to Operating Expense increases, notwithstanding that the Lease 
term may have terminated before the end of such Comparison Year.

5.  SECURITY DEPOSIT. Lessee shall deposit with Lessor upon execution hereof 
the security deposit set forth in paragraph 1.9 of the Basic Lease Provisions 
as security for Lessee's faithful performance of Lessee's obligations 
hereunder. If Lessee fails to pay rent or other charges due hereunder, or 
otherwise defaults with respect to any provision of this Lease, Lessor may 
use, apply or retain all or any portion of said deposit for the payment of 
any rent or other charge in default 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 said deposit, Lessee shall within ten 
(10) days after written demand therefor deposit cash with Lessor in an amount 
sufficient to restore said deposit to the full amount then required of 
Lessee. If the monthly Base Rent shall, from time to time, increase during 
the term of this Lease, Lessee shall, at the time of such increase, deposit 
with Lessor additional money as a security deposit so that the total amount 
of the security deposit held by Lessor shall at all times bear the same 
proportion to the then current Base Rent as the initial security deposit 
bears to the initial Base Rent set forth in paragraph 1.6 of the Basic Lease 
Provisions. Lessor shall not be required to keep said security deposit 
separate from its general accounts. If Lessee performs all of Lessee's 
obligations hereunder, said deposit, or so much thereof as has not heretofore 
been applied by Lessor, shall be returned, without payment of interest or 
other increment for its use, to Lessee (or, at Lessor's option, to the last 
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 said Security 
Deposit.

6.  USE.

    6.1  USE. The Premises shall be used and occupied only for the purpose 
set forth in paragraph 1.4 of the Basic Lease Provisions or any other use 
which is reasonably comparable to that use and for no other purpose.

    6.2  COMPLIANCE WITH LAW.

         (a) Lessor warrants to Lessee that the Premises, in the state 
existing on the date that the Lease term commences, but without regard to 
alterations or improvements made by Lessee or the use for which Lessee will 
occupy the Premises, does not violate any covenants or restrictions of 
record, or any applicable building code, regulation or ordinance in effect on 
such Lease term Commencement Date. In the event it is determined that this 
warranty has been violated, then it shall be the obligation of the Lessor, 
after written notice from Lessee, to promptly, at Lessor's sole cost and 
expense, rectify any such violation.

         (b) Except as provided in paragraph 6.2(a) Lessee shall, at Lessee's 
expense, promptly comply with all applicable statutes, ordinances, rules, 
regulations, orders, covenants and restrictions of record, and requirements 
of any fire insurance underwriters or rating bureaus, now in effect or which 
may hereafter come into effect, whether or not they reflect a change in 
policy from that now existing, during the term or any part of the term 
hereof, relating in any manner to the Premises and the occupation and use by 
Lessee of the Premises. Lessee shall conduct its business in a lawful manner 
and shall not use or permit the use of the Premises or the Common Areas in 
any manner that will tend to create waste or a nuisance or shall tend to 
disturb other occupants of the Office Building Project.

    6.3  CONDITIONS OF PREMISES.

         (a) Lessor shall deliver the Premises to Lessee in a clean condition 
on the Lease Commencement Date (unless Lessee is already in possession) and 
Lessor warrants to Lessee that the plumbing, lighting, air conditioning, and 
heating system in the Premises shall be in good operating condition. In the 
event that it is determined that this warranty has been violated, then it 
shall be the obligation of Lessor, after receipt of written notice from 
Lessee setting forth with specificity the nature of the violation, to 
promptly, at Lessor's sole cost, rectify such violation.

         (b) Except as otherwise provided in this Lease, Lessee hereby 
accepts the Premises and the Office Building Project in their condition 
existing as of the Lease Commencement Date or the date that Lessee takes 
possession of the Premises, whichever is earlier, subject to all applicable 
zoning, municipal, county and state laws, ordinances and regulations 
governing and regulating the use of the Premises, and any easements, 
covenants or restrictions of record, and accepts this Lease subject thereto 
and to all matters disclosed thereby and by any exhibits attached hereto. 
Lessee acknowledges that it has satisfied itself by its own independent 
investigation that the Premises are suitable for its intended use, and that 
neither Lessor nor Lessor's agent or agents has made any representation or 
warranty as to the present or future suitability of the Premises, Common 
Areas, or Office Building Project for the conduct of Lessee's business.

7.  MAINTENANCE, REPAIRS, ALTERATIONS AND COMMON AREA SERVICES.

    7.1 LESSOR'S OBLIGATIONS. Lessor shall keep the Office Building Project, 
including the Premises, interior and exterior walls, roof, and common areas, 
and the equipment whether used exclusively for the Premises or in common with 
other premises, in good condition and repair; provided, however, Lessor shall 
not be obligated to paint, repair or replace wall coverings, or to repair or 
replace any improvements that are not ordinarily a part of the Building or 
are above then Building standards. Except as provided in paragraph 9.5, there 
shall be no abatement of rent or liability of Lessee on account of any injury 
or interference with Lessee's business with respect to any improvements, 
alterations or repairs made by Lessor to the Office Building Project or any 
part thereof. Lessee expressly waives the benefits of any statute now or 
hereafter in effect which would otherwise afford Lessee the right to make 
repairs at Lessor's expense or to terminate this Lease because of Lessor's 
failure to keep the Premises in good order, condition and repair.

    7.2 LESSEE'S OBLIGATIONS.

        (a) Notwithstanding Lessor's obligation to keep the Premises in good 
condition and repair, Lessee shall be responsible for payment of the cost 
thereof to Lessor as additional rent for that portion of the cost of any 
maintenance and repair of the Premises, or any equipment (wherever located) 
that serves only Lessee or the Premises, to the extent such cost is 
attributable to causes beyond normal wear and tear. Lessee shall be 
responsible for the cost of painting, repairing or replacing wall coverings, 
and to repair or replace any Premises Improvements that are not ordinarily a 
part of the Building or that are above then Building standards. Lessor may, 
at its option, upon reasonable notice, elect to have Lessee perform any 
particular such maintenance or repairs the cost of which is otherwise 
Lessee's responsibility hereunder.

        (b) On the last day of the term hereof, or on any sooner termination, 
Lessee shall surrender the Premises to Lessor in the same condition as 
received, ordinary wear and tear excepted, clean and free of debris. Any 
damage or deterioration of the Premises shall not be deemed ordinary wear and 
tear if the same could have been prevented by good maintenance practices by 
Lessee. Lessee shall repair any damage to the Premises occasioned by the 
installation or removal of Lessee's trade fixtures, alterations, furnishings 
and equipment. Except as otherwise stated in this Lease, Lessee shall leave 
the air lines, power panels, electrical distribution systems, lighting 
fixtures, air conditioning, window coverings, wall coverings, carpets, wall 
paneling, ceilings and plumbing on the Premises and in good operating 
condition.

    7.3  ALTERATIONS AND ADDITIONS.

         (a) Lessee shall not, without Lessor's prior written consent make 
any alterations, improvements, additions, Utility Installations or repairs 
in, on or about the Premises, or the Office Building Project. As used in this 
paragraph 7.3 the term "Utility Installation" shall mean carpeting, window 
and wall coverings, power panels, electrical distribution systems, lighting 
fixtures, air conditioning, plumbing, and telephone and telecommunication 
wiring and equipment. At the expiration of the term, Lessor may require the 
removal of any or all of said alterations, improvements, additions or Utility 
Installations, and the restoration of the Premises and the Office Building 
Project to their prior condition, at Lessee's expense. Should Lessor permit 
Lessee to make its own alterations, improvements, additions or Utility 
Installations, Lessee shall use only such contractor as has been expressly 
approved by Lessor, and Lessor may require Lessee to provide Lessor, at 
Lessee's sole cost and expense, a lien and completion bond in an amount equal 
to one and one-half times the estimated cost of such improvements, to insure 
Lessor against any liability for mechanic's and materialmen's liens and to 
insure completion of the work. Should Lessee make any alterations, 
improvements, additions or Utility Installations without the prior approval 
of Lessor, or use a contractor not expressly approved by Lessor, Lessor may, 
at any time during the term of this Lease, require that Lessee remove any 
part or all of the same.

         (b) Any alterations, improvements, additions or Utility 
Installations in or about the Premises or the Office Building Project that 
Lessee shall desire to make shall be presented to Lessor in written form, 
with proposed detailed plans. If Lessor shall give its consent to Lessee's 
making such alteration, improvement, addition or Utility Installation, the 
consent shall be deemed conditioned upon Lessee acquiring a permit to do so 
from the applicable governmental agencies, furnishing a copy thereof to 
Lessor prior to the commencement of the work, and compliance by Lessee with 
all conditions of said permit in a prompt and expeditious manner.

         (c) Lessee shall pay, when due, all claims for labor or materials 
furnished or alleged to have been furnished to or for Lessee at or for use in 
the Premises, which claims are or may be secured by any mechanic's or 
materialmen's lien against the Premises, the Building or the Office Building 
Project, or any interest therein.

         (d) Lessee shall give Lessor not less than ten (10) days' notice 
prior to the commencement of any work in the Premises by Lessee, and Lessor 
shall have the right to post notices of non-responsibility in or on the 
Premises or the Building as provided by law. If Lessee shall, in good faith, 
contest the validity of any such lien, claim or demand, then Lessee shall, at 
its sole expense defend itself and Lessor against the same and shall pay and 
satisfy

any such adverse judgment that may be rendered thereon before the 
enforcement thereof against the Lessor or the Premises, the Building or the 
Office Building Project, upon the condition that if Lessor shall require, 
Lessee shall furnish to Lessor a surety bond satisfactory to Lessor in an 
amount equal to such contested lien claim or demand indemnifying Lessor 
against liability for the same and holding the Premises, the Building and the 
Office Building Project free from the effect of such lien or claim. In 
addition, Lessor may require Lessee to pay Lessor's reasonable attorneys' 
fees and costs in participating in such action if Lessor shall decide it is 
to Lessor's best interest so to do.

       (e) All alterations, improvements, additions and Utility Installations 
(whether or not such Utility Installations constitute trade fixtures of 
Lessee), which may be made to the Premises by Lessee, including but not 
limited to, floor coverings, panelings, doors, drapes, built-ins, moldings, 
sound attenuation, and lighting and telephone or communication systems, 
conduit, wiring and outlets, shall be made and done in a good and workmanlike 
manner and of good and sufficient quality and materials and shall be the 
property of Lessor and remain upon and be surrendered with the Premises at 
the expiration of the Lease term, unless Lessor requires their removal 
pursuant to paragraph 7.3(a). Provided Lessee is not in default, 
notwithstanding the provisions of this paragraph 7.3(e), Lessee's personal 
property and equipment, other than that which is affixed to the Premises so 
that it cannot be removed without material damage to the Premises or the 
Building, and other than Utility Installations, shall remain the property of 
Lessee and may be removed by Lessee subject to the provisions of paragraph 
7.2.

       (f) Lessee shall provide Lessor with as-built plans and specifications 
for any alterations, improvements, additions or Utility Installations.

   7.4 UTILITY ADDITIONS. Lessor reserves the right to install new or 
additional utility facilities throughout the Office Building Project for the 
benefit of Lessor or Lessee, or any other lessee of the Office Building 
Project, including, but not by way of limitation, such utilities as plumbing, 
electrical systems, communication systems, and fire protection and detection 
systems, so long as such installations do not unreasonably interfere with 
Lessee's use of the Premises.

8. INSURANCE; INDEMNITY.

   8.1 LIABILITY INSURANCE--LESSEE. Lessee shall, at Lessee's expense, obtain 
and keep in force during the term of this Lease a policy of Comprehensive 
General Liability Insurance utilizing an Insurance Services Office standard 
form with Broad Form General Liability Endorsement (GL0404), or equivalent, 
in an amount of not less than $1,000,000 per occurrence of bodily injury and 
property damage combined or in a greater amount as reasonably determined by 
Lessor and shall insure Lessee with Lessor as an additional insured against 
liability arising out of the use, occupancy or maintenance of the Premises. 
Compliance with the above requirement shall not, however, limit the liability 
of Lessee hereunder.

   8.2 LIABILITY INSURANCE--LESSOR. 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 Office Building Project in an amount not less than 
$5,000,000.00 per occurrence.

   8.3 PROPERTY INSURANCE--LESSEE. Lessee shall, at Lessee's expense, obtain 
and keep in force during the term of this Lease for the benefit of Lessee, 
replacement cost fire and extended coverage insurance, with vandalism and 
malicious mischief, sprinkler leakage and earthquake sprinkler leakage 
endorsements, in an amount sufficient to cover not less than 100% of the full 
replacement cost, as the same may exist from time to time, of all of Lessee's 
personal property, fixtures, equipment and tenant improvements.

   8.4 PROPERTY INSURANCE--LESSOR. Lessor shall obtain and keep in force 
during the term of this Lease a policy or policies of insurance covering loss 
or damage to the Office Building Project Improvements, but not Lessee's 
personal property, fixtures, equipment or tenant improvements, in the amount 
of the full replacement cost thereof, as the same may exist from time to 
time, utilizing Insurance Services Office standard form, or equivalent, 
providing protection against all perils included within the classification of 
fire, extended coverage, vandalism, malicious mischief, plate glass, and such 
other perils as Lessor deems advisable or may be required by a lender having 
a lien on the Office Building Project. In addition, Lessor shall obtain and 
keep in force, during the term of this Lease, a policy of rental value 
insurance covering a period of one year, with loss payable to Lessor, which 
insurance shall also cover all Operating Expenses for said period. Lessee 
will not be named in any such policies carried by Lessor and shall have no 
right to any proceeds therefrom. The policies required by these paragraphs 
8.2 and 8.4 shall contain such deductibles as Lessor or the aforesaid lender 
may determine. In the event that the Premises shall suffer an insured loss as 
defined in paragraph 9.1(f) hereof, the deductible amounts under the 
applicable insurance policies shall be deemed an Operating Expense. Lessee 
shall not do or permit to be done anything which shall invalidate the 
insurance policies carried by Lessor. Lessee shall pay the entirety of any 
increase in the property insurance premium for the Office Building Project 
over what it was immediately prior to the commencement of the term of this 
Lease if the increase is specified by Lessor's insurance carrier as being 
caused by the nature of Lessee's occupancy or any act or omission of Lessee.

   8.5 INSURANCE POLICIES. Lessee shall deliver to Lessor copies of liability 
insurance policies required under paragraph 8.1 or certificates evidencing 
the existence and amounts of such insurance within seven (7) days after the 
Commencement Date of this Lease. No such policy shall be cancellable or 
subject to reduction of coverage or other modification except after thirty 
(30) days prior written notice to Lessor. Lessee shall, at least thirty (30) 
days prior to the expiration of such policies, furnish Lessor with renewals 
thereof.

   8.6 WAIVER OF SUBROGATION. Lessee and Lessor each hereby release and 
relieve the other, and waive their entire right of recovery against the 
other, for direct or consequential loss or damage arising out of or incident 
to the perils covered by property insurance carried by such party, whether 
due to the negligence of Lessor or Lessee or their agents, employees, 
contractors and/or invitees. If necessary all property insurance policies 
required under this Lease shall be endorsed to so provide.

   8.7 INDEMNITY. Lessee shall indemnify and hold harmless Lessor and its 
agents, Lessor's master or ground lessor, partners and lenders, from and 
against any and all claims for damage to the person or property of anyone or 
any entity arising from Lessee's use of the Office Building Project, or from 
the conduct of Lessee's business or from any activity, work or things done, 
permitted or suffered by Lessee in or about the Premises or elsewhere and 
shall further indemnify and hold harmless Lessor from and against any and all 
claims, costs and expenses arising from any breach or default in the 
performance of any obligation on Lessee's part to be performed under the 
terms of this Lease, or arising from any act or omission of Lessee, or any of 
Lessee's agents, contractors, employees, or invitees, and from and against 
all costs, attorney's fees, expenses and liabilities incurred by Lessor as 
the result of any such use, conduct, activity, work, things done, permitted 
or suffered, breach, default or negligence, and in dealing reasonably 
therewith, including but not limited to the defense or pursuit of any claim 
or any action or proceeding involved therein; and in case any action or 
proceeding be brought against Lessor by reason of any such matter, Lessee 
upon notice from Lessor shall defend the same at Lessee's expense by counsel 
reasonably satisfactory to Lessor and Lessor shall cooperate with Lessee in 
such defense. Lessor need not have first paid any such claim in order to be 
so indemnified. Lessee, as a material part of the consideration to Lessor, 
hereby assumes all risk of damage to property of Lessee or injury to persons, 
in, upon or about the Office Building Project arising from any cause and 
Lessee hereby waives all claims in respect thereof against Lessor.

   8.8 EXEMPTION OF LESSOR FROM LIABILITY. SEE ADDENDUM 55. Lessee hereby 
agrees that Lessor shall not be liable for injury to Lessee's business or any 
loss of income therefrom or for loss of or damage to the goods, wares, 
merchandise or other property of Lessee, Lessee's employees, invitees, 
customers, or any other person in or about the Premises or the Office 
Building Project, nor shall Lessor be liable for injury to the person of 
Lessee, Lessee's employees, agents or contractors, whether such damage or 
injury is caused by or results from theft, fire, steam, electricity, gas, 
water or rain, or from the breakage, leakage, obstruction or other defects of 
pipes, sprinklers, wires, appliances, plumbing, air conditioning or lighting 
fixtures, or from any other cause, whether said damage or injury results from 
conditions arising upon the Premises or upon other portions of the Office 
Building Project, or from other sources or places, or from new construction 
or the repair, alteration or improvement of any part of the Office Building 
Project, or of the equipment, fixtures or appurtenances applicable 
thereto, and regardless of whether the cause of such damage or injury or the 
means of repairing the same is inaccessible. Lessor shall not be liable for 
any damages arising from any act or neglect of any other lessee, occupant or 
user of the Office Building Project, nor from the failure of Lessor to 
enforce the provisions of any other lease of any other lessee of the Office 
Building Project.

   8.9 NO REPRESENTATION OF ADEQUATE COVERAGE. Lessor makes no representation 
that the limits or forms of coverage of insurance specified in this paragraph 
8 are adequate to cover Lessee's property or obligations under this Lease.

9. DAMAGE OR DESTRUCTION.

   9.1 DEFINITIONS.

       (a) "Premises Damage" shall mean if the Premises are damaged or 
destroyed to any extent.

       (b) "Premises Building Partial Damage" shall mean if the Building of 
which the Premises are a part is damaged or destroyed to the extent that the 
cost to repair is less than fifty percent (50%) of the then Replacement Cost 
of the building.

       (c) "Premises Building Total Destruction" shall mean if the Building 
of which the Premises are a part is damaged or destroyed to the extent that 
the cost to repair is fifty percent (50%) or more of the then Replacement 
Cost of the Building.

       (d) "Office Building Project Buildings" shall mean all of the 
buildings on the Office Building Project site.

       (e) "Office Building Project Buildings Total Destruction" shall mean 
if the Office Building Project Buildings are damaged or destroyed to the

Replacement Cost of the Office Building Project Buildings.

       (f) "Insured Loss" shall mean damage or destruction which was caused 
by an event required to be covered by the insurance described in paragraph 8. 
The fact that an Insured Loss has a deductible amount shall not make the loss 
an uninsured loss.

       (g) "Replacement Cost" shall mean the amount of money necessary to be 
spent in order to repair or rebuild the damaged area to the condition that 
existed immediately prior to the damage occurring, excluding all improvements

       (a) Insured Loss: Subject to the provisions of paragraphs 9.4 and 
9.5, if at any time during the term of this Lease there is damage which is an 
Insured Loss and which falls into the classification of other Premises Damage 
or Premises Building Partial Damage, then Lessor shall, as soon as reasonably 
possible and to the extent the acquired materials and labor are readily 
available through usual commercial channels at Lessor's expense, repair such 
damage (but not Lessee's fixtures, equipment or tenant improvements originally 
paid for by Lessee) to its condition existing at the time of the damage, and 
this Lease shall continue in full force and effect.

       (b) Uninsured Loss: Subject to the provisions of paragraphs 9.4 and 
9.5, if at any time during the term of this Lease there is damage which is 
not an insured Loss and which falls within the classification of Premises 
Damage or Premises Building Partial Damage, unless caused by a negligent or 
willful act of Lessee (in which event Lessee shall make the repairs at 
Lessee's expense), which damage prevents Lessee from making any substantial 
use of the Premises, Lessor may at Lessor's option either (i) repair such 
damage as soon as reasonably possible at Lessor's expense, in which event 
this Lease shall continue in full force and effect, or (ii) give written 
notice to Lessee within thirty (30) days after the date of the occurrence of 
such damage of Lessor's intention to cancel and terminate this Lease as of 
the date of the occurrence of such damage, in which event this Lease shall 
terminate as of the date of the occurrence of such damage.

  9.3  PREMISES BUILDING TOTAL DESTRUCTION; OFFICE BUILDING PROJECT TOTAL 
DESTRUCTION. Subject to the provisions of paragraphs 9.4 and 9.5, if at any 
time during the term of this Lease there is damage, whether or not it is an 
Insured Loss, which falls into the classification of either (i) Premises 
Building Total Destruction, or (ii) Office Building Project Total 
Destruction, then Lessor may at Lessor's option either (i) repair such damage 
or destruction as soon as reasonably possible at Lessor's expense (to the 
extent the required materials are readily available through usual commercial 
channels) to its condition existing at the time of the damage, but not 
Lessee's fixtures, equipment or tenant improvements, and this Lease shall 
continue in full force and effect, or (ii) give written notice to Lessee 
within thirty (30) days after the date of occurrence of such damage of 
Lessor's intention to cancel and terminate this Lease in which case this 
Lease shall terminate as of the date of the occurrence of such damage.

  9.4  DAMAGE NEAR END OF TERM.

       (a) Subject to paragraph 9.4(b), if at any time during the last twelve 
(12) months of the term of this Lease there is substantial damage to the 
Premises, Lessor may at Lessor's option cancel and terminate this Lease as of 
the date of occurrence of such damage by giving written notice to Lessee of 
Lessor's election to do so within 30 days after the date of occurrence of 
such damage.

       (b) Notwithstanding paragraph 9.4(a), in the event that Lessee has an 
option to extend or renew this Lease, and the time within which said option 
may be exercised has not yet expired, Lessee shall exercise such option, if 
it is to be exercised at all, no later than twenty (20) days after the 
occurrence of an Insured Loss falling within the classification of Premises 
Damage during the last twelve (12) months of the term of this Lease. If 
Lessee duly exercises such option during said twenty (20) day period, Lessor 
shall, at Lessor's expense, repair such damage, but not Lessee's fixtures, 
equipment or tenant improvements, as soon as reasonably possible and this 
Lease shall continue in full force and effect. If Lessee fails to exercise 
such option during said twenty (20) day period, than Lessor may at Lessor's 
option terminate and cancel this Lease as of the expiration of said twenty 
(20) day period by giving written notice to Lessee of Lessor's election to do 
so within ten (10) days after the expiration of said twenty (20) day period, 
notwithstanding any term or provision in the grant of option to the contrary.

  9.5  ABATEMENT OF RENT; LESSEE'S REMEDIES.

       (a) In the event Lessor repairs or restores the Building or Premises 
pursuant to the provisions of this paragraph 9, and any part of the Premises 
are not usable (including loss of use due to loss of access or essential 
services), the rent payable hereunder (including Lessee's Share of Operating 
Expense Increase) for the period during which such damage, repair or 
restoration continues shall be abated, provided (1) the damage was not the 
result of the negligence of Lessee, and (2) such abatement shall only be to 
the extent the operation and profitability of Lessee's business as operated 
from the Premises is adversely affected. Except for said abatement of rent, 
if any, Lessee shall have no claim against Lessor for any damage suffered by 
reason of any such damage, destruction, repair or restoration.

       (b) If Lessor shall be obligated to repair or restore the Premises or 
the Building under the provisions of this Paragraph 9 and shall not commence 
such repair or restoration within sixty (60) days after such occurrence, or 
if Lessor shall not complete the restoration and repair within six (6) months 
after such occurrence, Lessee may at Lessee's option cancel and terminate 
this Lease by giving Lessor written notice of Lessee's election to do so at 
any time prior to the commencement of completion, respectively, of such 
repair or restoration. In such event this Lease shall terminate as of the 
date of such notice.

       (c) Lessee agrees to cooperate with Lessor in connection with any such 
restoration and repair, including but not limited to the approval and/or 
execution of plans and specifications required.

  9.6 TERMINATION - ADVANCE PAYMENTS. Upon termination of this Lease pursuant 
to this paragraph 9, an equitable adjustment shall be made concerning advance 
rent and any advance payments made by Lessee to Lessor. Lessee shall, in 
addition, return to Lessee so much of Lessee's security deposit as has not 
theretofore been applied by Lessor.

  9.7 WAIVER. Lessor and Lessee waive the provisions of any statute which 
relate to termination of leases when leased property is destroyed and agree 
that such event shall be governed by the terms of this Lease.

10. REAL PROPERTY TAXES. 

  10.1 PAYMENT OF TAXES. SEE ADDENDUM 56. Lessor shall pay the real property 
tax, as defined in paragraph 10.3, applicable to the Office Building Project 
subject to reimbursement by Lessee of Lessee's Share of such taxes in accordance
with the provisions of paragraph 4.2, except as otherwise provided in 
paragraph 10.2.

  10.2 ADDITIONAL IMPROVEMENTS. Lessee shall not be responsible for paying 
any increase in real property tax specified in the tax assessor's records and 
work sheets as being caused by additional improvements placed upon the Office 
Building Project by other lessees or by Lessor for the exclusive enjoyment of 
any other lessee. Lessee shall, however, pay to Lessor at the time that 
Operation Expenses are payable under paragraph 4.2(c) the entirety of any 
increase in real property tax if assessed solely by reason of additional 
improvements placed upon the Premises by Lessee or at Lessee's request.

  10.3 DEFINITION OF "REAL PROPERTY TAX." As used herein, the term "real 
property tax" shall include any form of real estate tax or assessment, 
general, special, ordinary or extraordinary, and any license fee, commercial 
rental tax, improvement bond or bonds, levy or tax (other than inheritance, 
personal income or estate taxes) imposed on the Office Building Project or 
any portion thereof by any authority having the direct or indirect power to 
tax, including any city, county, state or federal government, or any school, 
agricultural, sanitary, fire, street, drainage or other improvement district 
thereof, as against any legal or equitable interest of Lessor in the Office 
Building Project or in any portion thereof, as against Lessor's right to rent 
or other income therefrom, and as against Lessor's business of leasing the 
Office Building Project. The term "real property tax" shall also include any 
tax, fee, levy, assessment of charge (i) in substitution of, partially or 
totally, any tax, fee, levy, assessment or charge hereinabove included within 
the definition of "real property tax," of (ii) the nature of which was 
hereinbefore included within the definition of "real property tax," or 
(iii) which is imposed for a service or right not charged prior to June 1, 1978 
or, if previously charged, has been increased since June 1, 1978, or (iv) which 
is imposed as a result of a change in ownership, as defined by applicable local 
statutes for property tax purposes, of the Office Building Project or which 
is added to a tax or charge hereinbefore included within the definition of 
real property tax by reason of such change of ownership, or (v) which is 
imposed by reason of this transaction, any modifications or changes hereto, or 
any transfers hereof.

  10.4 JOINT ASSESSMENTS. If the improvements or property, the taxes for 
which are to be paid separately by Lessee under paragraph 10.2 or 10.5 are 
not separately assessed, Lessee's portion of that tax shall be equitably 
determined by Lessor from the respective valuations assigned in the 
assessor's work sheets or such other information (which may include the cost 
of construction) as may be reasonably available. Lessor's reasonable 
determination thereof, in good faith, shall be conclusive.

  10.5 PERSONAL PROPERTY TAXES.
     
          (a) Lessee shall pay prior to delinquency all taxes assessed 
against and levied upon trade fixtures, furnishings, equipment and all other 
personal property of Lessee contained in the Premises or elsewhere.

          (b) If any of Lessee's said personal property shall be assessed with 
Lessor's real property, Lessee shall pay to Lessor the taxes attributable to 
Lessee within ten (10) days after receipt of a written statement setting 
forth the taxes applicable to Lessee's property.

11. UTILITIES. SEE ADDENDUM 52.

  11.1 SERVICES PROVIDED BY LESSOR. Lessor shall provide heating, 
ventilation, air conditioning, and janitorial service as reasonably 
required, reasonable amounts of electricity for normal lighting and office 
machines, water for reasonable and normal drinking and lavatory use, and 
replacement light bulbs and/or fluorescent tubes and ballasts for standard 
overhead fixtures.

  11.2 SERVICES EXCLUSIVE TO LESSEE. Lessee shall pay for all water, gas, 
heat, light, power, telephone and other utilities and services specially or 
exclusively supplied and/or metered exclusively to the Premises or to Lessee, 
together with any taxes thereon. If any such services are not separately 
metered to the Premises, Lessee shall pay at Lessor's option, either Lessee's 
Share or a reasonable proportion to be determined by Lessor of all charges 
jointly metered with other premises in the Building.

  11.3 HOURS OF SERVICE. Said services and utilities shall be provided during 
generally accepted business days and hours or such other days or hours as 
may hereafter be set forth. Utilities and services required at other times 
shall be subject to advance request and reimbursement by Lessee to Lessor of 
the cost thereof.

     11.4 EXCESS USAGE BY LESSEE. Lessee shall not make connection to the 
utilities except by or through existing outlets and shall not install or use 
machinery or equipment in or about the Premises that uses excess water, 
lighting or power, or suffer or permit any act that causes extra burden upon 
the utilities or services, including but not limited to security services, 
over standard office usage for the Office Building Project. Lessor shall 
require Lessee to reimburse Lessor for any excess expenses or costs that may 
arise out of a breach of this subparagraph by Lessee. Lessor may, in its sole 
discretion, install at Lessee's expense supplemental equipment and/or 
separate metering applicable to Lessee's excess usage or loading.

     11.5 INTERRUPTIONS. There shall be no abatement of rent and Lessor shall 
not be liable in any respect whatsoever for the inadequacy, stoppage, 
interruption or discontinuance of any utility or service due to riot, strike, 
labor dispute, breakdown, accident, repair or other cause beyond Lessor's 
reasonable control or in cooperation with governmental request or directions.

12. ASSIGNMENT AND SUBLETTING.

     12.1 LESSOR'S CONSENT REQUIRED. Lessee shall not voluntarily or by 
operation of law assign, transfer, mortgage, sublet, or otherwise transfer or 
encumber all or any part of Lessee's interest in the Lease or in the 
Premises, without Lessor's prior written consent, which Lessor shall not 
unreasonably withhold. Lessor shall respond to Lessee's request for consent 
hereunder in a timely manner and any attempted assignment, transfer, 
mortgage, encumbrance or subletting without such consent shall be void, and 
shall constitute a material default and breach of this Lease without the need 
for notice to Lessee under paragraph 13.1. "Transfer" within the meaning of 
this paragraph 12 shall include the transfer or transfers aggregating: (a) if 
Lessee is a corporation, more than twenty-five percent (25%) of the voting 
stock of such corporation, or (b) if Lessee is a partnership, more than 
twenty-five percent (25%) of the profit and loss participation in such 
partnership.

     12.2 LESSEE AFFILIATE. Notwithstanding the provisions of paragraph 12.1 
hereof, Lessee may assign or sublet the Premises, or any portion thereof, 
without Lessor's consent to any corporation which controls, is controlled by 
or is under common control with Lessee, or to any corporation resulting from 
the merger or consolidation with Lessee, or to any person or entity which 
acquires all the assets of Lessee as a going concern of the business that is 
being conducted on the Premises, all of which are referred to as "Lessee 
Affiliate"; provided that before such assignment shall be effective, (a) said 
assignee shall assume, in full, the obligations of Lessee under this Lease 
and (b) Lessor shall be given written notice of such assignment and 
assumption. Any such assignment shall not, in any way, affect or limit the 
liability of Lessee under the terms of this Lease even if after such 
assignment or subletting the terms of this Lease are materially changed or 
altered without the consent of Lessee, the consent of whom shall not be 
necessary.

     12.3 TERMS AND CONDITIONS APPLICABLE TO ASSIGNMENT AND SUBLETTING.

          (a) Regardless of Lessor's consent, no assignment or subletting 
shall release Lessee of Lessee's obligations hereunder or alter the primary 
liability of Lessee to pay the rent and other sums due Lessor hereunder 
including Lessee's Share of Operating Expense increase, and to perform all 
other obligations to be performed by Lessee hereunder.

          (b) Lessor may accept rent from any person other than Lessee 
pending approval or disapproval of such assignment.

          (c) Neither a delay in the approval or disapproval of such 
assignment or subletting, nor the acceptance of rent, shall constitute a 
waiver or estoppel of Lessor's right to exercise its remedies for the breach 
of any of the terms or conditions of this paragraph 12 or this Lease.

          (d) If Lessee's obligations under this Lease have been guaranteed 
by third parties, then an assignment or sublease, and Lessor's consent 
thereto, shall not be effective unless said guarantors give their written 
consent to such sublease and the terms thereof.

          (e) The consent by Lessor to any assignment or subletting shall not 
constitute a consent to any subsequent assignment or subletting by Lessee or 
to any subsequent or successive assignment or subletting by the sublessee. 
However, Lessor may consent to subsequent sublettings and assignments of the 
sublease or any amendments or modifications thereto without notifying Lessee 
or anyone else liable on the Lease or sublease and without obtaining their 
consent and such action shall not relieve such persons from liability under 
this Lease or said sublease; however, such persons shall not be responsible 
to the extent any such amendment or modification enlarges or increases the 
obligations of the Lessee or sublessee under this Lease or such sublease.

          (f) In the event of any default under this Lease, Lessor may 
proceed directly against Lessee, any guarantors or any one else responsible 
for the performance of this Lease, including the sublessee, without first 
exhausting Lessor's remedies against any other person or entity responsible 
therefor to Lessor, or any security held by Lessor or Lessee.

          (g) Lessor's written consent to any assignment or subletting of the 
Premises by Lessee shall not constitute an acknowledgement that no default 
then exists under this Lease of the obligations to be performed by Lessee nor 
shall such consent be deemed a waiver of any then existing default, except 
as may be otherwise stated by Lessor at the time.

          (h) The discovery of the fact that any financial statement relied 
upon by Lessor in giving its consent to an assignment or subletting was 
materially false shall, at Lessor's election, render Lessor's said consent 
null and void.

     12.4 ADDITIONAL TERMS AND CONDITIONS APPLICABLE TO SUBLETTING. 
Regardless of Lessor's consent, the following terms and conditions shall 
apply to any subletting by Lessee of all or any part of the Premises and 
shall be deemed included in all subleases under this Lease whether or not 
expressly incorporated therein:

          (a) Lessee hereby assigns and transfers to Lessor all of Lessee's 
interest in all rentals and income arising from any sublease heretofore or 
hereafter made by Lessee, and Lessor may collect such rent and income and 
apply same toward Lessee's obligations under this Lease; provided, however, 
that until a default shall occur in the performance of Lessee's obligations 
under this Lease, Lessee may receive, collect and enjoy the rents accruing 
under such sublease. Lessor shall not, by reason of this or any other 
assignment of such sublease to Lessor nor by reason of the collection of the 
rents from a sublessee, be deemed liable to the sublessee for any failure of 
Lessee to perform and comply with any of Lessee's obligations to such 
sublessee under such sublease. Lessee hereby irrevocably authorizes and 
directs any such sublessee, upon receipt of a written notice from Lessor 
stating that a default exists in the performance of Lessee's obligations 
under this Lease, to pay to Lessor the rents due and to become due under the 
sublease. Lessee agrees that such sublessee shall have the right to rely upon 
any such statement and request from Lessor, and that such sublessee shall pay 
such rents to Lessor without any obligation or right to inquire as to whether 
such default exists and notwithstanding any notice from or claim from Lessee 
to the contrary. Lessee shall have no right or claim against said sublessee 
or Lessor or any such rents so paid by said sublessee to Lessor.

          (b) No sublease entered into by Lessee shall be effective unless 
and until it has been approved in writing by Lessor. In entering into any 
sublease, Lessee shall use only such form of sublessee as is satisfactory to 
Lessor, and once approved by Lessor, such sublease shall not be changed or 
modified without Lessor's prior written consent. Any sublease shall, by 
reason of entering into a sublease under this Lease, be deemed, for the 
benefit of Lessor, to have assumed and agreed to conform and comply with each 
and every obligation herein to be performed by Lessee other than such 
obligations as are contrary to or inconsistent with provisions contained in a 
sublease to which Lessor has expressly consented in writing.

          (c) In the event Lessee shall default in the performance of its 
obligations under this Lease, Lessor at its option and without any obligation 
to do so, may require any sublessee to attorn to Lessor, in which event 
Lessor shall undertake the obligations of Lessee under such sublease from the 
time of the exercise of said option to the termination of such sublease; 
provided, however, Lessor shall not be liable for any prepaid rents or 
security deposit paid by such sublessee to Lessee or for any other prior 
defaults of Lessee under such sublease.

          (d) No sublessee shall further assign or sublet all or any part of 
the Premises without Lessor's prior written consent.

          (e) With respect to any subletting to which Lessor has consented, 
Lessor agrees to deliver a copy of any notice of default by Lessee to the 
sublessee. Such sublessee shall have the right to cure a default of Lessee 
within three (3) days after service of said notice of default upon such 
sublessee, and the sublessee shall have a right of reimbursement and offset 
from and against Lessee for any such defaults cured by the sublessee.

     12.5 LESSOR'S EXPENSES. In the event 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 Lessee proposes to 
do then Lessee shall pay Lessor's reasonable costs and expenses incurred in 
connection therewith, including attorneys', architects', engineers' or other 
consultants' fees.

     12.6 CONDITIONS TO CONSENT. Lessor reserves the right to condition any 
approval to assign or sublet upon Lessor's determination that (a) the 
proposed assignee or sublessee shall conduct a business on the Premises of a 
quality substantially equal to that of Lessee and consistent with the general 
character of the other occupants of the Office Building Project and not in 
violation of any exclusives or rights then held by other tenants, and (b) the 
proposed assignee or sublessee be at least as financially responsible as 
Lessee was expected to be at the time of the execution of this Lease or of 
such assignment or subletting, whichever is greater.

13. DEFAULTS; REMEDIES.

     13.1 DEFAULT. The occurrence of any one or more of the following events 
shall constitute a material default of this Lease by Lessee:

          (a) The vacation or abandonment of the Premises by Lessee. Vacation 
of the Premises shall  include the failure to occupy the Premises for a 
continuous period of sixty (60) days or more, whether or not the rent is paid.

          (b) The breach by Lessee of any of the covenants, conditions or 
provisions of paragraphs 7.3(a), (b) or (d) (alterations), 12.1 (assignment 
or subletting), 13.1(a) (vacation or abandonment), 13.1(e) (insolvency), 
13.1(f) (false statement), 16(a) (estoppel certificate), 30(b) 
(subordination), 33 (auctions), or 41.1 (easements), all of which are hereby 
deemed to be material, non-curable defaults without the necessity of any 
notice by Lessor to Lessee thereof.

          (c) The failure by Lessee to make any payment of rent or any other 
payment required to be made by Lessee hereunder, as and when due, where such 
failure shall continue for a period of three (3) days after written notice 
thereof from Lessor to Lessee. In the event that Lessor serves Lessee with a 
Notice to Pay Rent or Quit pursuant to applicable Unlawful Detainer statutes
such Notice to Pay Rent or Quit shall also constitute the notice required by 
this subparagraph.

      (d) The failure by Lessee to observe or perform any of the covenants, 
conditions or provisions of this Lease to be observed or performed by Lessee 
other than those referenced in subparagraphs (b) and (c) above, where 
such failure shall continue for a period of thirty (30) days after written 
notice thereof from Lessor to Lessee; provided, however, that if the nature 
of Lessee's noncompliance is such that more than thirty (30) days are 
reasonably required for its cure, then Lessee shall not be deemed to be in 
default if Lessee commenced such cure within said thirty (30) day period and 
thereafter diligently pursues such cure to completion. To the extent 
permitted by law, such thirty (30) day notice shall constitute the sole and 
exclusive notice required to be given to Lessee under applicable Unlawful 
Detainer statutes.

      (e) (i) The making by Lessee of any general arrangement or general 
assignment for the benefit of creditors; (ii) Lessee becoming a "debtor" as 
defined in II U.S.C. Section 101 or any successor statute thereto (unless, in 
the case of a petition filed against Lessee, the same is dismissed within 
sixty (60) days; (iii) the appointment of a trustee or receiver to take 
possession of substantially all of Lessee's assets located at the Premises or 
of Lessee's interest in this Lease, where possession is not restored to 
Lessee within thirty (30) days; or (iv) the attachment, execution or other 
judicial seizure of substantially all of Lessee's assets located at the 
Premises or of Lessee's interest in this Lease, where such seizure is not 
discharged within thirty (30) days. In the event that any provision of this 
paragraph 13.1(e) is contrary to any applicable law, such provision shall be 
of no force or effect.

      (f) The discovery by Lessor that any financial statement given to 
Lessor by Lessee, or its successor in interest or by any guarantor of 
Lessee's obligation hereunder, was materially false.

   13.2 REMEDIES. In the event of any material default or breach of this 
Lease by Lessee, Lessor may at any time thereafter, with or without notice or 
demand and without limiting Lessor in the exercise of any right or remedy 
which Lessor may have by reason of such default:

      (a) Terminate Lessee's right to possession of the Premises by any 
lawful means, in which case this Lease and the term hereof shall terminate 
and Lessee shall immediately surrender possession of the Premises to Lessor. 
In such event Lessor shall be entitled to recover from Lessee all damages 
incurred by Lessor by reason of Lessee's default including, but not limited 
to, the cost of recovering possession of the Premises: expenses of reletting, 
including necessary renovation and alteration of the Premises, reasonable 
attorneys' fees, and any real estate commission actually paid; the worth at 
the time of award by the court having jurisdiction thereof of the amount by 
which the unpaid rent for the balance of the term after the time of such 
award exceeds the amount of such rental loss for the same period that Lessee 
proves could be reasonably avoided; that portion of the leasing commission 
paid by Lessor pursuant to paragraph 15 applicable to the unexpired term of 
this Lease.

      (b) Maintain Lessee's right to possession in which case this Lease 
shall continue in effect whether or not Lessee shall have vacated or 
abandoned the Premises. In such event Lessor shall be entitled to enforce all 
of Lessor's rights and remedies under this Lease, including the right to 
recover the rent as it becomes due hereunder.

     (c) Pursue any other remedy now or hereafter available to Lessor under 
the laws or judicial decisions of the state wherein the Premises are located. 
Unpaid installments of rent and other unpaid monetary obligations of Lessee 
under the terms of this Lease shall bear interest from the date due at the 
maximum rate then allowable by law.

   13.3 DEFAULT BY LESSOR. Lessor shall not be in default unless Lessor fails 
to perform obligations required of Lessor within a reasonable time, but in no 
event later than thirty (30) days after written notice by Lessee to Lessor 
and to the holder of any first mortgage or deed of trust covering the 
Premises whose name and address shall have theretofore been furnished to 
Lessee in writing, specifying wherein Lessor has failed to perform such 
obligation; provided, however, that if the nature of Lessor's obligation is 
such that more than thirty (30) days are required for performance then Lessor 
shall not be in default if Lessor commences performance within such 30-day 
period and thereafter diligently pursues the same to completion.

   13.4 LATE CHARGES. Lessee hereby acknowledges that late payment by Lessee 
to Lessor of Base Rent, Lessee's Share of Operating Expense Increase or 
other sums due hereunder will cause Lessor to incur costs not contemplated by 
this Lease, the exact amount of which will be extremely difficult to 
ascertain. Such costs include, but are not limited to, processing and 
accounting charges, and late charges which may be imposed on Lessor by the 
terms of any mortgage or trust deed covering the Office Building Project. 
Accordingly, if any installment of Base Rent, Operating Expense Increase, or 
any other sum due from Lessee shall not be received by Lessor or Lessor's 
designee within five (5) days after such amount shall be due, then, without 
any requirement for notice to Lessee, Lessee shall pay to Lessor a late 
charge equal to 10% 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 granted hereunder.

14.  CONDEMNATION.  If the Premises or any portion thereof or the Office 
Building Project are taken under the power of eminent domain, or sold under 
the threat of the exercise of said power (all of which are herein called 
"condemnation"), this Lease shall terminate as to the part so taken as of the 
date of the condemning authority takes title or possession, whichever first 
occurs; provided that if so much of the Premises or the Office Building 
Project are taken by such condemnation as would substantially and adversely 
affect the operation and profitability of Lessee's business conducted from 
the Premises, Lessee shall have the option, to be exercised only in writing 
within thirty (30) days after Lessor shall have given Lessee written notice 
of such taking (or in the absence of such notice, within thirty (30) days 
after the condemning authority shall have taken possession), to terminate 
this Lease as of the date the condemning authority takes such possession. If 
Lessee does not terminate this Lease in accordance with the foregoing, this 
Lease shall remain in full force and effect as to the portion of the Premises 
remaining, except that the rent and Lessee's Share of Operating Expense 
Increase shall be reduced in the proportion that the floor area of the 
Premises taken bears to the total floor area of the Premises. Common Areas 
taken shall be excluded from the Common Areas usable by Lessee and no 
reduction of rent shall occur with respect thereto or by reason thereof. 
Lessor shall have the option in its sole discretion to terminate this Lease 
as of the taking of possession by the condemning authority, by giving written 
notice to Lessee of such election within thirty (30) days after receipt of 
notice of a taking by condemnation of any part of the Premises or the Office 
Building Project.  Any award for the taking of all or any part of the 
Premises or the Office Building Project under the power of eminent domain or 
any payment made under threat of the exercise of such power shall be the 
property of Lessor, whether such award shall be made as compensation for 
diminution in value of the leasehold or for the taking of the fee, or as 
severance damages, provided, however, that Lessee shall be entitled to any 
separate award for loss of or damage to Lessee's trade natures, removable 
personal property and unamortized tenant improvements that have been paid for 
by Lessee.  For that purpose the cost of such improvements shall be amortized 
over the original term of this Lease excluding any options.  In the event 
that this Lease is not terminated by reason of such condemnation, Lessor 
shall to the extent of severance damages received by Lessor in connection 
with such condemnation, repair any damage to the Premises caused by such 
condemnation except to the extent that Lessee has been reimbursed therefor by 
the condemning authority.  Lessee shall pay any amount in excess of such 
severance damages required to complete such repair.

15. BROKER'S FEE.

     (a) The brokers involved in this transaction WILL BE PAID BY 
LESSOR as "listing broker" and _______________________ as "cooperating broker,"
licensed real estate broker(s).  A "cooperating broker" is defined as any 
broker other than the listing broker entitled to a share of any commission 
arising under this Lease.  Upon execution of this Lease by both parties, Lessor
shall pay to said brokers jointly, or in such separate shares as they may 
mutually designate in writing, a fee as set forth in a separate agreement 
between Lessor and said broker(s), or in the event there is no separate 
agreement between Lessor and said broker(s), the sum of $_____________ for 
brokerage services rendered by said broker(s) to Lessor in this transaction.

     (b) Lessor further agrees that (i) if Lessee exercises any Option, as 
defined in paragraph 39.1 of this Lease, which is granted to Lessee under 
this Lease, or any subsequently granted option which is substantially similar 
to an Option granted to Lessee under this Lease, or (ii) if Lessee acquires 
any rights to the Premises or other premises described in this Lease which 
are substantially similar to what Lessee would have acquired had an Option 
herein granted to Lessee been exercised, or (iii) if Lessee remains in 
possession of the Premises after the expiration of the term of this Lease 
after having failed to exercise an Option, or (iv) if said broker(s) are the 
procuring cause of any other lease or sale entered into between the parties 
pertaining to the Premises and/or any adjacent property in which Lessor has 
an interest, or (v) if the Base Rent is increased, whether by agreement or 
operation of an escalation clause contained herein, then as to any of said 
transactions or rent increases, Lessor shall pay said broker(s) a fee in 
accordance with the schedule of said broker(s) in effect at the time of 
execution of this Lease. Said fee shall be paid at the time such increased 
rental is determined.

     (c) Lessor agrees to pay said fee not only on behalf of Lessor but also 
on behalf of any person, corporation, association, or other entity having an 
ownership interest in said real property or any part thereof, when such fee 
is due hereunder. Any transferee of Lessor's interest in this Lease, whether 
such transfer is by agreement or by operation of law, shall be deemed to have 
assumed Lessor's obligation under this paragraph 15. Each listing and 
cooperating broker shall be a third party beneficiary of the provisions of 
this paragraph 15 to the extent of their interest in any commission arising 
under this Lease and may enforce that right directly against Lessor; 
provided, however, that all brokers having a right to any part of such total 
commission shall be a necessary party to any suit with respect thereto.

     (d) Lessee and Lessor each represent and warrant to the other that 
neither has had any dealings with any person, firm, broker or finder (other 
than the person(s), if any, whose names are set forth in paragraph 15(a), 
above) in connection with the negotiation of this Lease and/or the 
consummation of the transaction contemplated hereby, and no other broker or 
other person, firm or entity is entitled to any commission or finder's fee in 
connection with said transaction and Lessee and Lessor do each hereby 
indemnify and hold the other harmless from and against any costs, expenses, 
attorney's fees or liability for compensation or charges which may be claimed 
by any such unnamed broker, finder or other similar party by reason of any 
dealings or actions of the indemnifying party.

16. ESTOPPEL CERTIFICATE.

     (a) Each party (as "responding party") shall at any time upon not less 
than ten (10) days' prior written notice from the other party ("requesting 
party") execute, acknowledge and deliver to the requesting party a statement 
in writing (i) certifying that this Lease is unmodified and in full force and 
effect (or, if modified, stating the nature of such modification and 
certifying that this Lease, as so modified, is in full force and effect) and

to which the rent and other charges are paid in advance, if any, and (ii) 
acknowledging that there are not, to the responding party's knowledge, any 
uncured defaults on the part of the requesting party, or specifying such 
defaults if any are claimed.  Any such statement may be conclusively relied 
upon by any prospective purchaser or encumbrancer of the Office Building 
Project or of the business of Lessee.

    (b) At the requesting party's option, the failure to deliver such 
statement within such time shall be a material default of this Lease by the 
party who is to respond, without any further notice to such party, or it 
shall be conclusive upon such party that (i) this Lease is in full force and 
effect, without modification, except as may be represented by the requesting 
party, (ii) there are no uncured defaults in the requesting party's 
performance, and (iii) if Lessor is the requesting party, not more than one 
month's rent has been paid in advance.

    (c) If Lessor desires to finance, refinance, or sell the Office Building 
Project, or any part thereof, Lessee hereby agrees to deliver to any lender 
or purchaser designated by Lessor such financial statements of Lessee as may 
be reasonably required by such lender or purchaser.  Such statements shall 
include the past three (3) years' financial statements of Lessee.  All such 
financial statements shall be received by Lessor and such lender or purchaser 
in confidence and shall be used only for the purposes herein set forth.

17. LESSOR'S LIABILITY. The term "Lessor" as used herein shall mean only the 
owner or owners, at the time in question, of the fee title or a lessee's 
interest in a ground lease of the Office Building Project, and except as 
expressly provided in paragraph 15, in the event of any transfer of such 
title or interest, Lessor herein named (and in case of any subsequent 
transfers then the grantor) shall be relieved from and after the date of such 
transfer of all liability as respects Lessor's obligations thereafter to be 
performed, provided that any funds in the hands of Lessor or the then grantor 
at the time of such transfer, in which Lessee has an interest, shall be 
delivered to the grantee.  The obligations contained in this Lease to be 
performed by Lessor shall, subject as aforesaid, be binding on Lessor's 
successors and assigns, only during their respective periods of ownership.

18. SEVERABILITY. The invalidity of any provision of this Lease as 
determined by a court of competent jurisdiction shall in no way affect the 
validity of any other provision hereof.

19. INTEREST ON PAST-DUE OBLIGATIONS. Except as expressly herein provided, 
any amount due to Lessor not paid when due shall bear interest at the maximum 
rate then allowable by law or judgments from the date due. Payment of such 
interest shall not excuse or cure any default by Lessee under this Lease; 
provided, however, that interest shall not be payable on late charges 
incurred by Lessee nor on any amounts upon which late charges are paid by 
Lessee.

20. TIME OF ESSENCE. Time is of the essence with respect to the obligations 
to be performed under this Lease.

21. ADDITIONAL RENT. All monetary obligations of Lessee to Lessor under the 
terms of this Lease, including but not limited to Lessee's Share of Operating 
Expense increase and any other expenses payable by Lessee hereunder shall be 
deemed to be rent.

22. INCORPORATION OF PRIOR AGREEMENTS; AMENDMENTS. This Lease contains all 
agreements of the parties with respect to any matter mentioned herein.  No 
prior or contemporaneous agreement or understanding pertaining to any such 
matter shall be effective.  This Lease may be modified in writing only, 
signed by the parties in interest at the time of the modification.  Except as 
otherwise stated in this Lease, Lessee hereby acknowledges that neither the 
real estate broker listed in paragraph 15 hereof nor any cooperating broker 
on this transaction nor the Lessor or any employee or agents of any of said 
persons has made any oral or written warranties or representations to Lessee 
relative to the condition or use by Lessee of the Premises or the Office 
Building Project and Lessee acknowledges that Lessee assumes all 
responsibility regarding the Occupational Safety Health Act, the legal use 
and adaptability of the Premises and the compliance thereof with all 
applicable laws and regulations in effect during the term of this Lease.

23. NOTICES. Any notice required or permitted to be given hereunder shall be 
in writing and may be given by personal delivery or by certified or 
registered mail, and shall be deemed sufficiently given if delivered or 
addressed to Lessee or to Lessor at the address noted below or adjacent to 
the signature of the respective parties, as the case may be.  Mailed notices 
shall be deemed given upon actual receipt at the address required, or 
forty-eight hours following deposit in the mail, postage prepaid, whichever 
first occurs.  Either party may by notice to the other specify a different 
address for notice purposes except that upon Lessee's taking possession of 
the Premises, the Premises shall constitute Lessee's address for notice 
purposes.  A copy of all notices required or permitted to be given to Lessor 
hereunder shall be concurrently transmitted to such party or parties at such 
addresses as Lessor may from time to time hereafter designate by notice to 
Lessee.

24. WAIVERS. No waiver by Lessor of any provision hereof shall be deemed a 
waiver of any other provision hereof or of any subsequent breach by Lessee of 
the same or any other provision.  Lessor's consent to, or approval of, any 
act shall not be deemed to render unnecessary the obtaining of Lessor's 
consent to or approval of any subsequent act by Lessee.  The acceptance of 
rent hereunder by Lessor shall not be a waiver of any preceding breach by 
Lessee of any provision hereof, other than the failure of Lessee to pay the 
particular rent so accepted, regardless of Lessor's knowledge of such 
preceding breach at the time of acceptance of such rent.

25. RECORDING. Either Lessor or Lessee shall, upon request of the other, 
execute, acknowledge and deliver to the other a "short form" memorandum of 
this Lease for recording purposes.

26. HOLDING OVER. If Lessee, with Lessor's consent, remains in possession of 
the Premises or any part thereof after the expiration of the term hereof, 
such occupancy shall be a tenancy from month to month upon all the
provisions of this Lease pertaining to the obligations of Lessee, except that 
the rent payable shall be two hundred percent (200%) of the rent payable 
immediately preceding the termination date of this Lease, and all Options, if 
any, granted under the terms of this Lease shall be deemed terminated and be 
of no further effect during said month to month tenancy.

27. CUMULATIVE REMEDIES. No remedy or election hereunder shall be deemed 
exclusive but shall, wherever possible, be cumulative with all other remedies 
at law or in equity.

28. COVENANTS AND CONDITIONS. Each provision of this Lease performable by 
Lessee shall be deemed both a covenant and a condition.

29. BINDING EFFECT; CHOICE OF LAW. Subject to any provisions hereof 
restricting assignment or subletting by Lessee and subject to the provisions 
of paragraph 17, this Lease shall bind the parties, their personal 
representatives, successors and assigns. This Lease shall be governed by the 
laws of the State where the Office Building Project is located and any 
litigation concerning this Lease between the parties hereto shall be 
initiated in the county in which the Office Building Project is located.

30. SUBORDINATION. 

    (a) This Lease, and any Option or right of first refusal granted hereby, 
at Lessor's option, shall be subordinate to any ground lease, mortgage, deed 
of trust, or any other hypothecation or security now or hereafter placed upon 
the Office Building Project and to any and all advances made on the security 
thereof and to all renewals, modifications, consolidations, replacements and 
extensions thereof. Notwithstanding such subordination, Lessee's right to 
quiet possession of the Premises shall not be disturbed if Lessee is not in 
default and so long as Lessee shall pay the rent and observe and perform all 
of the provisions of this Lease, unless this Lease is otherwise terminated 
pursuant to its terms. If any mortgagee, trustee or ground lessor shall elect 
to have this Lease and any Options granted hereby prior to the lien of its 
mortgage, deed of trust or ground lease, and shall give written notice 
thereof to Lessee, this Lease and such Options shall be deemed prior to such 
mortgage, deed of trust or ground lease, whether this Lease or such Options 
are dated prior or subsequent to the date of said mortgage, deed of trust or 
ground lease or the date of recording thereof.

    (b) Lessee agrees to execute any documents required to effectuate an 
attornment, a subordination, or to make this Lease or any Option granted 
herein prior to the lien of any mortgage, deed of trust or ground lease, as 
the case may be. Lessee's failure to execute such documents within ten (10) 
days after written demand shall constitute a material default by Lessee 
hereunder without further notice to Lessee or, at Lessor's option, Lessor 
shall execute such documents on behalf of Lessee as Lessee's 
attorney-in-fact. Lessee does hereby make, constitute and irrevocably appoint 
Lessor as Lessee's attorney-in-fact and in Lessee's name, place and stead, to 
execute such documents in accordance with this paragraph 30(b).

31. ATTORNEYS' FEES. 

    31.1 If either party or the broker(s) named herein bring an action to 
enforce the terms hereof or declare rights hereunder, the prevailing party in 
any such action, trial or appeal thereon, shall be entitled to his reasonable 
attorneys' fees to be paid by the losing party as fixed by the court in the 
same or a separate suit, and whether or not such action is pursued to 
decision or judgment. The provisions of this paragraph shall inure to the 
benefit of the broker named herein who seeks to enforce a right hereunder.

    31.2 The attorneys' fee award shall not be computed in accordance with 
any court fee schedule, but shall be such as to fully reimburse all 
attorneys' fees reasonably incurred in good faith.

    31.3 Lessor shall be entitled to reasonable attorneys' fees and all other 
costs and expenses incurred in the preparation and service of notice of 
default and consultations in connection therewith, whether or not a legal 
transaction is subsequently commenced in connection with such default.

32. LESSOR'S ACCESS.

    32.1 Lessor and Lessor's agents shall have the right to enter the 
Premises at reasonable times for the purpose of inspecting the same, 
performing any services required of Lessor, showing the same to prospective 
purchasers, lenders, or lessees, taking such safety measures, erecting such 
scaffolding or other necessary structures, making such alterations, repairs, 
improvements or additions to the Premises or to the Office Building Project 
as Lessor may reasonably deem necessary or desirable and the erecting, using 
and maintaining of utilities, services, pipes and conduits through the 
Premises and/or other premises as long as there is no material adverse effect 
to Lessee's use of the Premises. Lessor may at any time place on or about the 
Premises or the Building any ordinary "For Sale" signs and Lessor may at any 
time during the last 120 days of the term hereof place on or about the 
Premises any "For Lease" signs.

    32.2 All activities of Lessor pursuant to this paragraph shall be without 
abatement of rent, nor shall Lessor have any liability to Lessee for the same.

     32.3 Lessor shall have the right to retain keys to the Premises and to 
unlock all doors in or upon the Premises other than to files, vaults and 
safes, and in the case of emergency to enter the Premises by any reasonably 
appropriate means, and any such entry shall not be deemed a forceable or 
unlawful entry or detainer of the Premises or an eviction.  Lessee waives any 
charges for damages or injuries or interference with Lessee's property or 
business in connection therewith.

     33. AUCTIONS. Lessee shall not conduct, nor permit to be conducted, either 
voluntarily or involuntarily, any auction upon the Premises or the Common 
Areas without first having obtained Lessor's prior written consent.  
Notwithstanding anything to the contrary in this Lease, Lessor shall not be 
obligated to exercise any standard of reasonableness in determining whether 
to grant such consent.  The holding of any auction on the Premises or Common 
Areas in violation of this paragraph shall constitute a material default of 
this Lease.

     34. SIGNS. Lessee shall not place any sign upon the Premises or the Office 
Building Project without Lessor's prior written consent.  Under no 
circumstances shall Lessee place a sign on any roof of the Office Building 
Project.

     35. MERGER. The voluntary or other surrender of this Lease by Lessee, or a 
mutual cancellation thereof, or a termination by Lessor, shall not work a
merger, and shall, at the option of Lessor, terminate all or any existing 
subtenancies or may, at the option of Lessor, operate as an assignment to 
Lessor of any or all of such subtenancies.

     36. CONSENTS. Except for paragraphs 33 (auctions) and 34 (signs) hereof, 
wherever in this Lease the consent of one party is required to an act of the 
other party such consent shall not be unreasonably withheld or delayed.

     37. GUARANTOR. In the event that there is a guarantor of this Lease, said 
guarantor shall have the same obligations as Lessee under this Lease.

     38. QUIET POSSESSION. Upon Lessee paying the rent for the Premises and 
observing and performing all of the covenants, conditions and provisions on 
Lessee's part to be observed and performed hereunder, Lessee shall have quiet 
possession of the Premises for the entire term hereof subject to all of the 
provisions of this Lease.  The individuals executing this Lease on behalf of 
Lessor represent and warrant to Lessee that they are fully authorized and 
legally capable of executing this Lease on behalf of Lessor and that such 
execution is binding upon all parties holding an ownership interest in the 
Office Building Project.

39. OPTIONS.

     39.1 DEFINITION. As used in this paragraph the word "Option" has the 
following meaning: (1) the right or option to extend the term of this Lease 
or to renew this Lease or to extend or renew any lease that Lessee has on 
other property of Lessor; (2) the option of right of first refusal to lease 
the Premises or the right of first offer to lease the Premises or the right 
of first refusal to lease other space within the Office Building Project or 
other property of Lessor or the right of first offer to lease other space 
within the Office Building Project or other property of Lessor; (3) the right 
or option to purchase the Premises or the Office Building Project, or the 
right of first refusal to purchase the Premises or the Office Building 
Project or the right of first offer to purchase the Premises or the Office 
Building Project, or the right or option to purchase other property of 
Lessor, or the right of first refusal to purchase other property of Lessor or 
the right of first offer to purchase other property of Lessor.

     39.2 OPTIONS PERSONAL. Each Option granted to Lessee in this Lease is 
personal to the original Lessee and may be exercised only by the original 
Lessee while occupying the Premises who does so without the intent of 
thereafter assigning this Lease or subletting the Premises or any portion 
thereof, and may not be exercised or be assigned, voluntarily or 
involuntarily, by or to any person or entity other than Lessee; provided, 
however, that an Option may be exercised by or assigned to any Lessee 
Affiliate as defined in paragraph 12.2 of this Lease.  The Options, if any, 
herein granted to Lessee are not assignable separate and apart from this 
Lease, nor may any Option be separated from this Lease in any manner, either 
by reservation or otherwise.

     39.3 MULTIPLE OPTIONS. In the event that Lessee has any multiple options 
to extend or renew this Lease a later option cannot be exercised unless the 
prior option to extend or renew this Lease has been so exercised.

<PAGE>

     39.4 EFFECT OF DEFAULT ON OPTIONS.

          (a) Lessee shall have no right to exercise an Option, 
notwithstanding any provision in the grant of Option to the contrary, (i) 
during the time commencing from the date Lessor gives to Lessee a notice of 
default pursuant to paragraph 13.1(c) or 13.1(d) and continuing until the 
noncompliance alleged in said notice of default is cured, or (ii) during the 
period of time commencing on the day after a monetary obligation to Lessor is 
due from Lessee and unpaid (without any necessity for notice thereof to 
Lessee) and continuing until the obligation is paid, or (iii) in the event 
that Lessor has given to Lessee three or more notices of default under 
paragraph 13.1(c), or paragraph 13.1(d), whether or not the defaults are 
cured, during the 12 month period of time immediately prior to the time that 
Lessee attempts to exercise the subject Option, (iv) if Lessee has committed 
any non-curable breach, including without limitation those described in 
paragraph 13.1(b), or is otherwise in default of any of the terms, covenants 
or conditions in this Lease.

         (b) The period of time within which an Option may be exercised shall 
not be extended or enlarged by reason of Lessee's inability to exercise an 
Option because of the provisions of paragraph 39.4(a).

         (c) All rights of Lessee under the provisions of an Option shall 
terminate and be of no further force or effect, notwithstanding Lessee's due 
and timely exercise of the Option, if, after such exercise and during the 
term of this Lease, (i) Lessee fails to pay to Lessor a monetary obligation 
of Lessee for a period of thirty (30) days after such obligation becomes due 
(without any necessity of Lessor to give notice thereof to Lessee), or (ii) 
Lessee fails to commence to cure a default specified in paragraph 13.1(d) 
within thirty (30) days after the date that Lessor gives notice to Lessee of 
such default and/or Lessee fails thereafter to diligently prosecute said cure 
to completion, or (iii) Lessor gives to Lessee three or more notices of default 
under paragraph 13.1(c), or paragraph 13.1(d), whether or not the defaults 
are cured, or (iv) if Lessee has committed any non-curable breach, including 
without limitation those described in paragraph 13.1(b), or is otherwise in 
default of any of the terms, covenants and conditions of this Lease.

40. SECURITY MEASURES -- LESSOR'S RESERVATIONS.

     40.1 Lessee hereby acknowledges that Lessor shall have no obligation 
whatsoever to provide guard service or other security measures for the 
benefit of the Premises or the Office Building Project.  Lessee assumes all 
responsibility for the protection of Lessee, its agents, and invitees and the 
property of Lessee and of Lessee's agents and invitees from acts of third 
parties.  Nothing herein contained shall prevent Lessor, at Lessor's sole 
option, from providing security protection for the Office Building Project or 
any part thereof, in which event the cost thereof shall be included within 
the definition of Operating Expenses, as set forth in paragraph 4.2(b).

     40.2 Lessor shall have the following rights:

         (a) To change the name, address or title of the Office Building 
Project or building in which the Premises are located upon not less than 90 
days prior written notice;

         (b) To, at Lessee's expense, provide and install Building standard 
graphics on the door of the Premises and such portions of the Common Areas as 
Lessor shall reasonably deem appropriate;

         (c) To permit any lessee the exclusive right to conduct any business 
as long as such exclusive does not conflict with any rights expressly given 
herein;

         (d) To place such signs, notices or displays as Lessor reasonably 
deems necessary or advisable upon the roof, exterior of the buildings of the 
Office Building Project or on pole signs in the Common Areas;

     40.3 Lessee shall not:

         (a) Use a representation (photographic or otherwise) of the Building 
or the Office Building Project or their name(s) in connection with Lessee's 
business;

         (b) Suffer or permit anyone, except in emergency, to go upon the

desirable and to cause the recordation of Parcel Maps and restrictions, so 
long as such easements, rights, dedications, Maps and restrictions do not

payment shall not be regarded as a voluntary payment, and there shall survive 
the right on the part of said party to institute suit for recovery of such 
sum.  If it shall be adjudged that there was no legal obligation on the part 
of said party to pay such sum or any part thereof, said party shall be 
entitled to recover such sum or so much thereof as it was not legally 
required to pay under the provisions of this Lease.

     basic monthly rent and all other charges due under the Lease, including 
     Lessee's share under Lease Paragraph 4.2 of increases in base building

     fluorescent lights) and toward additional maintenance, repair and 
     replacement on account of the reduction in the useful life of the 
     building components. The additional monthly charge, based upon current 
     expenses, shall be determined as follows:

             EMPLOYEES                     LUMP SUM
             ---------                     --------
              50 to 100                    $250.00
             101 to 120                    $300.00
             121 to 140                    $350.00

     The Lessor shall reserve the right to increase the monthly lump 
     sum for excess usage on a going-forward basis if the Lessor reasonably 
     determines over time that the actual cost of the excess usage exceeds 
     the applicable described amount.

     Lessee shall provide Lessor by not later than the 25th calendar day of 
     each month a statement certified by an officer of Lessee setting forth 
     the number of employees currently employed by it and the number of 
     employees that shall be employed by it effective as of the first 
     calendar day of the following month. Lessee shall pay to Lessor with 
     its next base monthly rent payment the lump sum allocable to the number 
     of projected employees as of the first day of the following month. If 
     Lessee fails to timely provide Lessor with such monthly statement, then 
     the lump sum which shall be due and payable shall be the highest lump 
     sum payable under the schedule set forth above.

     Finally, Lessor reserves the right to prohibit or deny the use of the 
     Premises by employees in excess of 140 people, and nothing set forth in 
     this letter shall constitute a waiver of Lessor's right to require 
     separate metering under Lease Paragraph 11.4, or to declare a default 
     for over-usage of the Office Building Project by employees in excess of 
     140.
