                               PROSPECTUS SUMMARY

   You should read the following summary together with the more detailed
information regarding Mercata and the financial statements and the notes to
those statements appearing elsewhere in this prospectus.

                                  Our Business

   We are a provider of Internet-based demand aggregation services. Our
business model empowers buyers with common purchasing interests to achieve
discounts on high-quality, brand-name products and services. Demand aggregation
operates on two basic principles: (1) sellers are more likely to offer
discounts to buyers when merchandise is purchased in volume and (2) buyers are
more likely to purchase merchandise as prices decrease. We call our Internet-
based form of demand aggregation "We-Commerce(TM)". On our Mercata.com Web
site, buyers participate in group buying through PowerBuy(TM) group purchases.
PowerBuys are limited-time buying opportunities in which the price of the
featured product or service dynamically decreases, based on parameters
determined by the seller, as more visitors join the buying group.

   Through the use of our proprietary business methods and technology,
individual buyers are able to combine their purchasing power to receive volume
pricing benefits on featured merchandise. Using this same technology, a seller
may gain access to actual buyer demand and price sensitivity data, enabling the
seller to adjust prices during a PowerBuy in order to achieve sales objectives,
such as increasing units sold, revenues, gross profit dollars or gross margin
percentage.

   For online businesses, we offer an e-commerce solution through our We-
Commerce Network. Currently, the We-Commerce Network has two principal types of
participants:

  .  merchants that desire to sell their products and services on their Web
     sites using a dynamic pricing mechanism and extend the reach of their
     merchandise offerings to other Web sites; and

  .  portal, community and content Web sites that desire to enhance their e-
     commerce capabilities by providing users a novel buying experience.

  Within this network of online businesses, PowerBuy group purchases can be
conducted simultaneously on multiple Web sites, thus potentially increasing the
number of individual buyers within any given PowerBuy. To date, participants in
the We-Commerce Network include DealTime.com, Inc., Football Northwest LLC
(Seahawks.com), Go2Net, Inc., Mercata.com, the Microsoft Network LLC (MSN),
mybytes.com (a division of Youthstream Media Networks, Inc.), Online Office
Supplies Company and SAVIshopper.com, Inc.

   We began offering products for sale on Mercata.com in May 1999. In the
fiscal year ended December 31, 1999, we generated net revenues of $6.3 million
and received orders from over 72,000 customer accounts.

                             Corporate Information

   We were incorporated in Delaware on September 23, 1998. Our principal
executive offices are located at 110 --110th Avenue N.E., Bellevue, Washington
98004. Our telephone number is (425) 468-9800. Our Web site is located at

   Mercata(TM), We-Commerce(TM), PowerBuy(TM), Share the Power(TM), Buying
Power to the People(TM), the Power Swirl design and The Power of We(TM) are
trademarks held by us. This prospectus also includes trademarks, trade names
and service marks of other companies. Use or display by Mercata of other
parties' trademarks, trade names or service marks is not intended to and does

                                  RISK FACTORS

   You should consider carefully the risks described below before making an
investment decision. The risks and uncertainties described below are not the
only ones we face. Additional risks and uncertainties presently not known to us
or that we currently deem immaterial may also impair our business operations.
If any of the following risks actually occur, our business, results of
operations and financial condition could be materially and adversely affected.
Additionally, the value of our stock could decline, and you may lose all or
part of your investment.

                         Risks Related to Our Business

Our limited operating history makes forecasting future results difficult.

   We were incorporated in September 1998 and began selling products on our
Mercata.com Web site in May 1999. Accordingly, we have only a limited operating
history on which you can evaluate our business and prospects. Our prospects
must be considered in the light of the risks, uncertainties, expenses and
difficulties frequently encountered by companies in their early stages of
development, particularly companies in new and rapidly evolving markets, such
as online commerce, and companies with new and unproven business models. You
must consider the risks associated with our ability to:

  .  execute successfully our business and marketing strategy;

  .  expand and enhance our product and service offerings;

  .  expand the We-Commerce Network;

  .  source merchandise and work with manufacturers, distributors and our
     third-party warehouse facility to fulfill orders;

  .  attract visitors to Mercata.com, convert visitors to customers,
     encourage repeat purchases and maintain a high level of customer
     satisfaction;

  .  maintain and enhance our brands;

  .  continue to develop and upgrade our technology; and

  .  attract, integrate, retain and motivate qualified personnel.

If we are unsuccessful in addressing these risks and uncertainties, our
business, results of operations and financial condition will be harmed.

Our business model is unproven.

   Our demand aggregation business model is unproven. We will be successful
only if buyers purchase and sellers offer products through Mercata.com or the
Web sites of other participants in the We-Commerce Network. Prior to the launch
of Mercata.com, we believe relatively few buyers and sellers had bought and
sold goods and services over the Internet using a group buying method. The
method of aggregating demand to reduce prices on products sold online is new
and may not become a popular method of purchasing goods and services.
Therefore, it is impossible to predict the degree to which buyers and sellers
will use our group buying service. It is possible that buyers and sellers will
never utilize our group buying service to the degree necessary for us to
achieve profitability or sustain our operations. In addition, merchandise
suppliers may be reluctant to use a newly-developed business model to
distribute and sell products. If we are unable to attract a sufficient number
of buyers or source a sufficient amount of merchandise, our business could be
harmed.

                                       6
<PAGE>

Failure to successfully promote and maintain our brands would adversely affect
our business.

   Our ability to develop and maintain awareness of the Mercata, We-Commerce
and PowerBuy brands is critical to achieving widespread acceptance of
Mercata.com and the We-Commerce Network, as well as our overall e-commerce
model. Due in part to the emerging nature of e-commerce and the substantial
resources available to many of our competitors, our opportunity to achieve and
maintain a significant market share may be limited. We launched our Web site in
May 1999 and, accordingly, we have had a limited amount of time to establish
our brands. Successfully promoting and positioning our brands will depend
largely on the effectiveness of our marketing efforts, our ability to source
desired products at competitive prices and our ability to attract well-known
companies to participate in the We-Commerce Network. If our planned marketing
efforts are ineffective, we may need to increase our financial commitment in
creating and maintaining brand awareness, which could divert financial and
management resources from other aspects of our business, or cause our operating
expenses to increase disproportionately to our revenues. In addition, our
inability to promote our brands successfully could result in decreased customer
awareness and lower sales on Mercata.com.

If we fail to expand the We-Commerce Network, our business will be harmed.

   Our success will depend, in part, on our ability to expand the number of
participants in the We-Commerce Network. Our failure to expand this network
could significantly harm our business. In addition to Mercata.com, we currently
have only eight participants in the We-Commerce Network, three of which are
affiliated with one of our significant stockholders. In addition, our
relationships with current We-Commerce Network participants may not be
indicative of relationships we may have with We-Commerce Network participants
in the future. To date, we have not generated any service fee revenues from the
We-Commerce Network. We do not know if we will ever be able to generate
revenues from the We-Commerce Network services we offer or to attract
additional participants to the We-Commerce Network.

   Our success will also depend, in part, on our ability and the ability of We-
Commerce Network participants to generate traffic, source merchandise and
generate sales transactions across the We-Commerce Network. For this to occur,
our existing and future network participants must drive sufficient numbers of
users to their e-commerce Web sites and must devote sufficient resources to
making their sites attractive to buyers and sellers. In addition, there must be
demand for the merchandise being offered on those sites. We have little control
over the activities or efforts of the participants in the We-Commerce Network.
We cannot assure you these participants will be successful in accomplishing any
of these objectives, and their failure to do so could impede our growth and
harm our business.

We may make mistakes when we set or adjust our PowerBuy pricing mechanism
during a PowerBuy purchasing period, which could result in reduced buyer
demand, adverse supplier reaction or decreased gross margins.

   In adjusting the price at which we offer a product or service during a
PowerBuy, we may make pricing decisions that reduce buyer demand, adversely
affect our suppliers or decrease our gross margins. We consider several factors
when making these pricing decisions, including customer acquisition,
maximization of gross margins, generation of revenues and the amount of product
available for sale. It is possible that, in an effort to pursue one or more of
these objectives, we could alienate buyers or otherwise harm our business. For
example, when our PowerBuy prices are adjusted to maximize margins, the price
of offered products may not fall to a level that would make it an attractive
purchase for most buyers, and therefore we could lose potential customers and
fail to sell the products. Likewise, a decision to reduce prices dramatically
in an effort to acquire new customers may negatively affect our gross margins
and our relationships with current or potential

                                       7
<PAGE>

suppliers. If we fail to anticipate adequately the buyer or supplier reaction
to, or the overall financial effect of, our PowerBuy management decisions, our
business will be harmed.

Our quarterly operating results vary significantly and may cause our stock
price to fluctuate.

   Our quarterly operating results have varied significantly in the past and
will vary significantly in the future, which makes it difficult for us to
predict our future operating results. Our future operating results may fall
below the expectations of securities analysts or investors, which would likely
cause the trading price of our common stock to decline. In addition, we may
make purchasing, pricing, customer acquisition, customer service, acquisition
or financing decisions that could adversely affect our operating results.

   Our quarterly operating results will fluctuate for several reasons,
including:

  .  our ability to attract visitors to Mercata.com, convert visitors to
     customers, encourage repeat purchases and maintain a high level of
     customer satisfaction;

  .  our ability to anticipate demand accurately;

  .  changes in gross margins of our current and future product and service
     offerings;

  .  the mix of products we sell;

  .  the mix of revenues derived from products we sell, and the revenues
     derived from We-Commerce Network services offered by us;

  .  introductions of new products and services by us or our competitors;

  .  technical difficulties, system downtime or Internet brownouts, including
     breakdowns in our system operations caused by security breaches;

  .  timing of upgrades and developments in our systems and infrastructure;

  .  the effects of any future acquisitions of technologies or businesses,
     and related integration efforts;

  .  our ability to prevent credit card fraud;

  .  our level of merchandise returns; and

  .  disruptions in service by common shipping carriers due to strikes or
     other occurrences.

   Both seasonal fluctuations in Internet usage and traditional retail cycles
affect our business. Internet usage generally declines during the summer. Sales
in traditional consumer retail markets usually increase significantly in the
fourth calendar quarter of each year. The fourth quarter seasonal impact may be
even more pronounced in certain product categories, such as consumer
electronics. For these reasons, you should not rely on period-to-period
comparisons of our financial results to forecast our future performance.

We have incurred significant net losses, and we expect to incur significant net
losses for the foreseeable future.

   Since our inception in 1998, we have incurred significant net losses,
resulting primarily from costs related to establishing our brands, developing
our proprietary business methods and technology, developing relationships with
distributors and other suppliers, attracting customers and building our user
databases. We incurred net losses of $1.9 million for the period from our
inception on September 23, 1998 to December 31, 1998 and $36.1 million for the
year ended December 31, 1999. As of December 31, 1999, we had an accumulated
deficit of approximately $38.0 million, and we expect to incur significant net
losses for the foreseeable future.

                                       8
<PAGE>

   To succeed, we must invest heavily in marketing and promotion, and in
developing our We-Commerce business methods, technology and operating
infrastructure. We expect to increase our operating expenses in order to
enhance our brands, expand the We-Commerce Network, increase our customer base,
support our growing infrastructure and introduce new products and services.
From time to time we sell products below target margins and, on rare occasions,
we sell merchandise below cost in order to acquire customers. In addition,
products sold using our PowerBuy pricing mechanism sometimes have lower gross
margins than fixed priced products. Accordingly, we may need to generate and
sustain substantially higher revenues in order to become profitable. If we do
achieve profitability, we cannot be certain we will be able to sustain
profitability on a quarterly or annual basis.

We depend on third parties to fulfill all of our customer orders, and any
problems with these parties could impair our operating results and harm our
reputation.

   In 1999, we relied on third-party distributors to fulfill approximately 67%
of our customers' orders in terms of revenues. The remaining orders were
fulfilled at our third-party warehouse. We cannot ensure that our fulfillment
partners fill our customers' orders accurately and that orders are shipped
promptly and in appropriate packaging. If any of our existing fulfillment
arrangements were to be terminated, our business could be disrupted, and we
could incur significant costs in attempting to make alternative arrangements.
Our distribution network is also dependent heavily upon third-party carriers,
primarily United Parcel Service, for product shipments. UPS accounted for
approximately 93% of our customer shipments by units in the fiscal year ended
December 31, 1999. We therefore are subject to the risk that labor shortages,
strikes, inclement weather or other factors may limit the ability of UPS and
other carriers to meet our shipping needs. Our shippers' failure to deliver
products to our customers in a timely manner would damage our reputation and
adversely affect our operating results. If UPS or our other existing shippers
are unable or unwilling to deliver our products to our customers, we will need
to arrange for alternative carriers. We may be unable to engage an alternative
carrier on a timely basis or upon terms favorable to us.

   Our third-party carriers may also increase their shipping rates. For
promotional reasons, we currently pay ground shipping charges for our
customers. For competitive reasons, we may be required to continue paying
shipping charges for our customers in the future, and any increase in shipping
charges would decrease our operating margins and could harm our business.

Because we do not have long-term or exclusive vendor contracts, we may not be
able to get sufficient quantities of products in a timely manner.

   If we are not able to offer our customers sufficient quantities of
merchandise in a timely manner, we could lose customers, and our net revenues
could decrease. In addition, we may be limited in our ability to obtain new or
popular products. Our success depends on our ability to procure these types of
products in sufficient quantities at competitive prices, particularly for the
holiday shopping season. As is common in the industry, we do not have long-term
or exclusive vendor arrangements that guarantee the availability of products
for resale. Therefore, we do not have a predictable or guaranteed supply of
such products.

If we fail to expand our fulfillment operations successfully, net revenues
could fall below expectations, and we could incur unexpected costs.

   We must be able to fill customer orders quickly and efficiently. If we do
not expand our third-party fulfillment operations and systems to accommodate
increases in demand, particularly during the holiday shopping season, we will
not be able to increase our net revenues in accordance with the expectations of
securities analysts and investors. We intend to add to the capacity of our
fulfillment operations by entering into agreements with additional fulfillment
partners. It may be difficult for us to

                                       9
<PAGE>

assimilate new partners into our fulfillment operations quickly or at all, or
to integrate their systems and technologies into ours. It is also possible that
our existing fulfillment partners may adopt new systems or technologies that
are difficult to integrate or are incompatible with ours. If we fail to
maintain or expand our fulfillment operations, we may lose sales and our
reputation may suffer. Even if we are successful in expanding our fulfillment
operations, our planned expansion may cause disruptions in our business, and
our fulfillment operations may be inadequate to accommodate increases in
customer demand.

We do not generate cash sufficient to fund our operations, and we will need
additional financing to continue our growth, which we may be unable to obtain.

   To date, we have funded our operations from the sale of equity and debt
securities and have not generated sufficient cash from operations. Cash from
operations must increase significantly for us to fund anticipated operating
expenses. If our cash flows are insufficient to fund these expenses, we will
need to fund our growth through additional equity or debt financings or reduce
costs. Poor financial results, unanticipated expenses or unanticipated
opportunities that require financial commitments could give rise to additional
financing requirements sooner than we expect. We may not be able to obtain this
financing on satisfactory terms, or at all. If we issue securities to raise
capital, our existing stockholders may experience additional dilution and the
new securities may have rights senior to those of our common stock. If adequate
funds are not available or are not available on acceptable terms, our ability
to enhance our services, fund our growth, respond to competitive pressures or
take advantage of business opportunities would be significantly limited, and we
might need to significantly restrict our operations.

We have experienced significant growth in our business in recent periods, and
any inability to manage this growth and any future growth could harm our
business.

   Our historical growth has placed, and any further growth likely will
continue to place, a significant strain on our management, administrative
resources, software and systems. Any failure to manage growth effectively could
seriously harm our business. We have grown from 39 employees on December 31,
1998 to 104 employees on December 31, 1999. We have also expanded our
operations significantly. To be successful, we will need to continue to
implement management information systems and improve our operating,
administrative, financial and accounting systems and controls. We will also
need to train new employees and maintain close coordination among our executive
management, merchandising, operations, program management and Web site design,
engineering, customer acquisition and retention and customer service
organizations. These processes are time consuming and expensive, will increase
management responsibilities and will divert management attention from other
business concerns.

Failure to adapt to changing technology may negatively affect our business.

   To remain competitive, we must continue to enhance and improve our
proprietary group buying business methods and technology, including our We-
Commerce business methods and technology, and the functionality and features of
Mercata.com, the We-Commerce Network and the systems we use to process
customers' orders and payments. We may need to adopt wireless and broadband
technologies to facilitate better access to our services. The Internet and the
online commerce industry are changing rapidly. Competitors may introduce new
technologies, or use new or existing technologies more effectively. In
addition, new industry standards and practices may emerge. If we do not respond
quickly and effectively to these developments, our existing Web site,
proprietary business methods, technology and systems may become obsolete and
visitors could stop using Mercata.com or the We-Commerce Network. Our business
could also be affected negatively by technical difficulties, system downtime,
Internet brownouts or break-ins by unauthorized persons.


                                       10

Our ability to expand our registered user and customer database and to keep
this database current and confidential is critical to our success.

   Failure to keep our proprietary registered user and customer database
current and confidential, or the damage to or the destruction of the
information in this proprietary database, could seriously harm our business.
Our failure to expand effectively our database of registered users and
customers to create targeted direct marketing offers, or enhance and refine our
techniques for segmenting this information to maximize its usefulness, may harm
our business. In addition, if federal or state governments enact privacy
legislation resulting in the increased regulation of electronic mailing lists,
we could experience increased costs in complying with potential regulations
concerning the solicitation of consents to keep or add customer names to our
mailing lists.

We may not be able to compete successfully against current and future
competitors.

   The e-commerce market is new, rapidly evolving and intensely competitive. We
expect competition to intensify in the future because current and new
competitors can enter our market and launch new Web sites and e-commerce
services at a relatively low cost. For example, Yahoo! Inc. recently announced
that it will be entering the group buying market in the second half of 2000,
and America Online, Inc. announced it will do so during the first quarter of
2000. Increased competition is likely to result in price reductions, reduced
gross margins and loss of market share, any of which could seriously harm our
net sales and results of operations.

   We currently or potentially compete with a variety of companies, including:

  .  other group buying services such as Accompany, Inc. and Letsbuyit.com,
     NV;

  .  Internet portals such as America Online, Inc. and Yahoo! Inc.;

  .  online retailers such as 800.com Inc., Amazon.com, Inc., Buy.com, Inc.
     and Priceline.com;

  .  providers of e-commerce services or functionality such as Fairmarket,
     Inc., Freemarkets, Inc., MySimon Inc. and Inktomi Corporation;

  .  business-to-business sellers such as Onvia.com, Inc. and Staples, Inc.;
     and

  .  traditional brick and mortar retailers such as Circuit City Stores,
     Inc., Costco Wholesale Corporation and Wal-Mart Stores, Inc.

   Many of our online and traditional store-based competitors have longer
operating histories, larger customer or user bases, greater brand recognition
and significantly greater financial, marketing and other resources than we do.
Many of these competitors also can devote substantially more resources to Web
site and systems development and may be better able to leverage customer bases
and supplier and other relationships. In addition, large, well-established or
well-financed manufacturers and retailers may join with online competitors, or
other companies as the use of the Internet and other online services increases.

   Our competitors may be able to procure products from vendors on more
favorable terms, fulfill customer orders more efficiently, adopt more
aggressive pricing or inventory availability policies and attract more clients
for their e-commerce services than we. Our online competitors may also adopt
new technologies or methods that have greater performance and features than
ours. We also may face additional competition as we expand our product and
service offerings into new categories. In addition, new technologies and the
expansion of existing technologies, such as price comparison programs, may
increase competition. Dealing with these competitors may require significant
additional expenditures and could affect our business, results of operations
and financial condition. We cannot assure you that we will be able to compete
successfully against these competitors.

Online security breaches could seriously harm our business.

   If third parties are able to penetrate our network security or otherwise
misappropriate users' personal or credit card information, we could be subject
to liability. Our liability could include claims for unauthorized purchases
with credit card information, impersonation or other similar fraud claims as
well as for other misuses of personal information, such as for unauthorized
marketing purposes. These claims could result in costly and time-consuming
litigation which could harm our business and divert the attention of management
from other concerns.

   In addition, anyone who is able to circumvent our security measures could
cause interruptions in our operations. Recently, several well-known Web sites
were targeted by unauthorized persons and experienced short-term disruptions in
service. We cannot assure you we will be able to prevent similar disruptions of
service. Breaches such as this could seriously harm our business.

We depend on our key personnel and the loss of any key personnel may harm our
business.

   Our success depends to a significant degree upon the continued contributions
of our key management, engineering, sales and marketing and finance personnel,
many of whom would be difficult to replace. In particular, we rely on our
President and Chief Executive Officer, Tom Van Horn. In addition, several key
members of our management team joined us in February 2000, including Scott
Scharfman, our Chief Financial Officer, and Warren Meyer, our Executive Vice
President of the We-Commerce Network. Our future success depends on these
officers effectively working together with our original management team. The
loss of services of any of our key personnel, especially the services of Mr.
Van Horn, may seriously harm our business and results of operations. We do not
have employment contracts or maintain "key person" life insurance policies for
any of our key personnel.

   We devote, and will continue to devote, substantial resources to attract
high-quality employees. Competition for such personnel is intense, particularly
in high technology centers such as the Pacific Northwest. In making employment
decisions, particularly in the Internet and high technology industries, job
candidates often consider the value of stock options they may receive in
connection with their employment. If the value of our common stock decreases,
it could harm our recruiting efforts. If we do not succeed in attracting new
personnel or retaining and motivating our current personnel, our business could
be harmed.

If the protection of our technology and intellectual property is inadequate,
our business could be harmed and our brands and reputation could suffer.

   We regard our pending patents, copyrights, service marks, trademarks, trade
dress, trade secrets and similar intellectual property as critical to our
success. We rely on patent, trademark and copyright law, trade secret
protection and confidentiality or license agreements with our employees,
consultants, customers, partners and others to protect our proprietary rights.
The steps we take to protect our proprietary rights may be inadequate.
Effective patent, trademark, service mark, copyright and trade secret
protection may not be available in every country in which we will sell our
products and services online. We believe that there are companies that have
infringed our trademarks in the past, and similar infringements may occur in
the future. Any infringement of our trademarks could result in customer
confusion, damage to our reputation or brands and harm to our business.

   We have filed 11 United States and international patent applications
relating to our demand aggregation business methods and technology. We also
endeavor to identify and protect new inventions. Nevertheless, it is possible
that:

  .  our pending patent applications may not result in the issuance of any
     patents;

  .  if our pending patents are issued, one or more of these patents could be
     challenged successfully by third parties, which could result in the loss
     of our right to prevent others from exploiting the group buying methods
     and technology claimed in such patents;

                                       12
<PAGE>

  .  if our pending patents are issued, our ability to rely on one or more of
     these patents to offer our demand aggregation services could be
     prevented if third parties prevail in an interference action in the U.S.
     Patent and Trademark Office and thereby obtain priority of invention for
     the subject matter claimed in any issued patents; and

  .  current and future competitors could devise new methods of competing
     with our business that are not covered by our patent applications.

   We currently are aware of several online businesses that appear to use group
buying transaction models. Any patents issued to us may not prevent these or
other competitors from developing and operating e-commerce businesses that use
a group buying-based approach.

Intellectual property claims against us can be costly and could impair our
business.

   Other parties may assert infringement or unfair competition claims against
us. Although we have not been notified of any such claims to date, we cannot
predict whether third parties will assert claims of infringement against us, or
whether any future assertions or prosecutions will harm our business. If we are
forced to defend against any such claims, whether they are with or without
merit or are determined in our favor, we may face costly litigation and
diversion of technical and management personnel. As a result of such a dispute,
we may have to develop non-infringing business methods or technology or enter
into royalty or licensing agreements. Such royalty or licensing agreements, if
required, may be unavailable on terms acceptable to us, or at all. The patent
field covering Internet-related business methods and technologies is new and
rapidly evolving and surrounded by a great deal of uncertainty, and we believe
other pending patent applications relating to demand aggregation may exist. If
there is a successful claim of patent infringement against us, and we are
unable to develop non-infringing business methods and technology or license the
infringed or similar technology on a timely basis, it would impair our
business.

If we cannot protect our domain names, it will impair our ability to
successfully build our brands.

   We may be unable to acquire or maintain Web domain names relating to our
brands in the United States and other countries in which we may conduct
business. As a result, we may be unable to prevent third parties from acquiring
and using domain names relating to our brands. Such use could damage our brands
and reputation and take customers away from our Web site. We currently hold
over 50 domain names, including "www.mercata.com". The acquisition and
maintenance of domain names generally is regulated by Internet regulatory
bodies. Governing bodies may establish additional top-level domains, appoint
additional domain name registrars or modify the requirements for holding domain
names. If we cannot prevent others from using similar domain names we may be
unable to successfully build our brands, which could negatively affect our
business. Furthermore, the relationship between regulations governing domain
names and laws protecting trademarks and similar proprietary rights is unclear.
Therefore, we may be unable to prevent third parties from acquiring domain
names that are similar to, infringe upon or otherwise decrease the value of our
trademarks and other proprietary rights.

Our facilities and systems are vulnerable to natural disasters and other
unexpected problems, and the occurrence of a natural disaster or other
unexpected problem could damage our reputation and reduce our net sales.

   Substantially all of our computer, communications and information systems
and our administrative offices are housed at our leased office space in
Bellevue, Washington. The occurrence of an earthquake, fire, flood, volcanic
eruption or other natural disaster or unanticipated problems such as power
loss, telecommunications failure or break-in at our headquarters could cause

                                       13
<PAGE>

interruptions or delays in our business, loss of data or render us unable to
accept and fulfill customer orders. In addition, substantially all of our
computer hardware for operating our Web site currently is located at the
facilities of Exodus Communications, Inc. in Tukwila, Washington. We currently
do not have a backup system in place. In addition, we have no formal disaster
recovery plan. Our business interruption insurance may not compensate us
adequately for losses that may occur. In addition, the failure to obtain the
data communications capacity required by us, as a result of human error,
natural disaster or other operational disruptions, could result in
interruptions in our service. The occurrence of any or all of these similar
events could damage our reputation and impair our business.

We plan to increase our inventory levels, and we may have to write down the
value of our inventory if buyer demand changes after we order products.

   Although currently we rely primarily on our distributors to carry most of
the inventory available for purchase on Mercata.com, we anticipate that we will
carry an increasing amount of inventory and that the absolute dollar value of
sales derived from our own inventory will rise. We hold inventory because some
manufacturers do not have direct distribution channels in place, and may not be
willing to establish such channels. As a result, our success will depend, in
part, on our ability to predict accurately the rapidly changing trends in
preferences for products that we sell and to avoid overstocking unpopular
products. Predicting these trends is difficult. If demand for one or more of
these products falls short of our expectations, we may be required to take
significant inventory markdowns, which could reduce our net revenues and gross
margins. This risk may be greatest in the first calendar quarter of each year,
after we have increased significantly our inventory levels for the holiday
shopping season. In addition, to the extent that demand for our products
increases over time, we may be forced to increase inventory levels. Any
increase would subject us to additional inventory risks.

Because a key element of our strategy is to generate a high volume of traffic
on Mercata.com, our business could be harmed by capacity constraints.

   A key element of our strategy is to generate a high volume of traffic on,
and purchases at, our Web site. Accordingly, the satisfactory performance,
reliability and availability of Mercata.com, transaction-processing systems and
network infrastructure are critical to our reputation, as well as our ability
to attract and retain customers and maintain a high level of customer service.
Our revenues depend upon the number of visitors who shop on our Mercata.com Web
site and the volume of orders that we can fulfill. Any system interruptions
that result in the unavailability of Mercata.com or reduced order fulfillment
would reduce the volume of goods that we sell and the attractiveness of our
product offerings. We have experienced periodic system interruptions in the
past, and we believe that system interruptions may continue to occur in the
future. For example, in January 2000, we had a system interruption which caused
our Web site to be unavailable for approximately 110 minutes. Any substantial
increase in the volume of traffic on Mercata.com or the number of orders placed
by customers will require that we expand and upgrade our technology,
transaction-processing systems and network infrastructure. We may not be able
to project accurately the rate or timing of increases, if any, in the use of
Mercata.com, or necessary expansions of and upgrades to our technology,
transaction-processing systems and network infrastructure to accommodate these
increases.

We may be sued for information retrieved from Mercata.com or from the
We-Commerce Network.

   We may be subject to claims for defamation, negligence, copyright or
trademark infringement, personal injury or other legal theories relating to the
information we publish on Mercata.com or that participants in the We-Commerce
Network might publish on their Web sites. These types of claims

                                       14
<PAGE>

have been brought, sometimes successfully, against Web site operators and
providers of online services. We could also be subject to claims based upon the
content that is accessible from our Web site through links to other Web sites
or through content and materials that may be posted by users on bulletin boards
or in chat rooms operated by us or by third parties. Our insurance, which
covers commercial general liability and advertising injuries, may not
adequately protect us against these types of claims.

International expansion could impose substantial burdens on our resources and
divert management's attention from domestic operations

   We intend to explore opportunities for expanding our business into
international markets. International expansion of our operations could impose
substantial burdens on our resources, divert management's attention from
domestic operations, and otherwise harm our business. This expansion into
international markets will require extensive management attention and
resources. In addition, we may need to rely extensively on third parties in
foreign countries to help conduct our international operations, coordinate with
foreign Web sites and conduct sales and marketing efforts. Our success in
international markets will depend to a large degree on the success of these
third parties, over whom we may have little control, and on their willingness
to dedicate sufficient resources to our relationships. Furthermore,
international operations are subject to several risks, including:

  .  local distribution monopolies;

  .  difficulties and costs of staffing and managing foreign offices;

  .  the impact of recessions in economies outside the United States;

  .  changes in regulatory requirements;

  .  export restrictions;

  .  greater uncertainty regarding the protection of intellectual property
     rights;

  .  adverse tax consequences;

  .  political and economic instability;

  .  tariffs and other trade barriers; and

  .  fluctuations in currency exchange rates.

Our failure to address these risks adequately could harm our business.

                     Risks Related To The Internet Industry

Our long-term success depends on the development of the electronic commerce
market, which is uncertain.

   Our future sales depend substantially upon the widespread acceptance and use
of the Internet as an effective medium of commerce by consumers. Demand for
recently introduced products and services such as ours over the Internet is
subject to a high level of uncertainty. We cannot be certain our sales will
grow at the same rate as forecasted for other segments of the Internet. The
development of the Internet as a viable commercial marketplace is subject to a
number of risks, including whether potential customers are willing to shift
their purchasing from traditional vendors to online vendors and whether
communication services are adequate to promote the acceptance of the Internet
as an effective commerce medium. In addition, the increased use of the Internet
as a medium for commerce raises concerns about Internet security, reliability,
pricing, accessibility and quality of service. If use of the Internet does not
continue to grow, or grows at a slower rate than we

                                       15
<PAGE>

anticipate, or if the necessary Internet infrastructure or complementary
services are not developed to support effectively the growth that may occur,
our business could be harmed.

If we become subject to additional burdens associated with government
regulation, our sales may decline and our business may be negatively affected.

   Any new legislation or regulation could hinder the growth of the Internet
and other online services generally and decrease the acceptance of the Internet
and other online services as media of commerce. Laws and regulations directly
applicable to Internet communications, commerce and advertising are becoming
more prevalent. Laws and regulations may be adopted covering issues such as
user privacy, pricing, content, taxation and quality of products and services.
Federal, state and foreign governments might attempt to regulate our activities
or levy sales or other taxes relating to our activities. The laws governing the
Internet are largely unsettled, even in areas where legislation has been
enacted. It may take years to determine whether and how existing laws such as
those governing taxation apply to the Internet. In addition, the growth and
development of the market for e-commerce may prompt calls for more stringent
consumer protection and privacy laws, both in the United States and abroad,
which may impose additional burdens on companies conducting business online.
For example, the Federal Trade Commission and state agencies have been
investigating various Internet companies regarding their use of personal
information of Internet users. In addition, the European Union Directive on the
Protection of Personal Data may affect our ability to expand into Europe if we
or participants in the We-Commerce Network do not afford adequate privacy to
users of our sites. We could incur additional expenses or otherwise lose our
ability to grow our database if new regulations regarding the use of personal
information of Internet users are introduced, or if our uses of this
information are investigated. We do not currently have insurance to cover these
types of losses. The adoption or modification of laws or regulations relating
to the Internet and other online services could cause our sales to decline and
negatively affect our business.

   All of our services are subject to federal and state consumer protection
laws and regulations prohibiting unfair and deceptive trade practices. We are
also subject to related "plain language" statutes in place in many
jurisdictions, which require the use of simple, easy-to-read terms and
conditions in contracts with consumers. If we fail to comply with these laws
and regulations, our business may suffer.

                         Risks Related To This Offering

We may apply the net proceeds of this offering to uses that do not improve our
results of operations or increase our market value.

   Our management will have considerable discretion in the application of the
net proceeds of this offering, and you will not have the opportunity, as part
of your initial investment decision, to assess whether the net proceeds are
being used appropriately. The net proceeds of this offering may be used for
corporate purposes that do not improve our results of operations or our market
value. Pending application of the net proceeds, they may be placed in
investments that do not produce income or that lose value. See "Use of
Proceeds".

Executive officers, directors and entities affiliated with them will continue
to have substantial control over us after the offering, which could delay or
prevent a change in our corporate control favored by our other stockholders.

   Executive officers, directors and entities affiliated with them, if acting
together, would be able to influence significantly all matters requiring
approval by our stockholders, including the election of directors and the
approval of mergers or other business combination transactions. These

                                       16
<PAGE>

stockholders will beneficially own, in the aggregate, approximately   % of our
common stock following the completion of this offering,   % if the
overallotment option is exercised in full. In particular, Vulcan Ventures
Incorporated will control approximately   % of our common stock after this
offering,   % if the overallotment option is exercised in full. The interests
of these stockholders may differ from the interests of other stockholders. As a
result, these stockholders could approve or cause us to take actions of which
you disapprove or that are contrary to your interests and those of other
investors.

It may be difficult for a third party to acquire us even if doing so would be
beneficial to our stockholders.

   Provisions of our Certificate of Incorporation, our Bylaws, Delaware law and
Washington law could make it more difficult for a third party to acquire us,
even if doing so would be beneficial to our stockholders. See "Description of
Capital Stock -- Antitakeover Effects of Charter Documents, Delaware Law and
Washington Law" and "Management-Board Composition".

There has been no prior market for our common stock, our stock price may
experience extreme price and volume fluctuations and any volatility in our
stock price could result in claims against us.

   Prior to this offering, investors could not buy or sell our common stock
publicly. An active public market for our common stock may not develop or be
sustained after the offering. The initial public offering price will be
determined by negotiations between us and the representatives of the
underwriters. The market price of our common stock may decline below the
initial public offering price after this offering.

   Fluctuations in market price and volume are particularly common among
securities of e-commerce and other Internet companies. The market price of our
common stock may fluctuate significantly in response to the following factors,
many of which are beyond our control:

  .  variations in quarterly operating results;

  .  changes in market valuations of Internet and other e-commerce companies;

  .  our announcements relating to significant contracts, acquisitions,
     strategic partnerships, joint ventures or capital commitments;

  .  additions or departures of key personnel;

  .  future sales of common stock; and

  .  changes in financial estimates by securities analysts.

   In the past, securities class action litigation has often been brought
against companies following periods of volatility in the market price of their
common stock. We may be the target of similar litigation. Securities litigation
could result in substantial costs and divert management's time and attention.

Substantial future sales of our common stock in the public market may depress
our stock price.

   Sales of a substantial number of shares of our common stock after this
offering could cause our stock price to fall. In addition, the sale of these
shares could impair our ability to raise capital through the sale of additional
stock. Our current stockholders hold a substantial number of shares, which they
will be able to sell in the public market in the near future. All of the shares
sold in this offering will be

                                       17
<PAGE>

freely tradable. The 31,927,951 other shares outstanding, based on the number
of shares outstanding as of March 1, 2000, will be restricted securities as
defined in Rule 144 of the Securities Act of 1933. Approximately 28,075,701 of
those shares will be freely tradable beginning 180 days after the effective
date of this offering, and the remainder of these will become freely tradable
at various times thereafter.

The purchasers in this offering will immediately experience substantial
dilution in net tangible book value.

   The initial public offering price is expected to be substantially higher
than the book value per share of our outstanding common stock immediately after
the offering. Accordingly, if you purchase common stock in the offering, you
will incur immediate dilution of approximately $    in the book value per share
of our common stock from the price you pay for our common stock, based upon an
assumed initial public offering price of $     . In addition, we have issued
options to acquire common stock at prices significantly below the assumed
initial public offering price. To the extent that these outstanding options are
ultimately exercised, you will experience further dilution.

                   NOTE REGARDING FORWARD-LOOKING STATEMENTS

   This prospectus contains forward-looking statements that relate to future
events or our future financial performance, which involve risks and
uncertainties. We use words such as "may", "will", "should", "expects",
"plans", "anticipates", "believes", "estimates", "potential" or "continue" and
similar expressions to identify forward-looking statements. These statements
are only predictions. Our actual results could differ materially from those
anticipated in these forward-looking statements as a result of various factors,
including those discussed under "Risk Factors" and elsewhere in this
prospectus.

                                USE OF PROCEEDS

   The net proceeds we will receive from the sale of shares of our common stock
in this offering are estimated to be $   million, or $   million if the
underwriters exercise their overallotment option in full, assuming an offering
price of $   per share and after deducting underwriting discounts and
commissions and estimated offering expenses we will pay.

   The principal purposes of this offering are to increase our working capital,
to create a public market for our common stock, to facilitate our future access
to the public capital markets and to increase our visibility in the e-commerce
marketplace. We expect to use the net proceeds from this offering principally
for working capital and for general corporate purposes, including marketing and
the expansion of the We-Commerce Network. In addition, we may use a portion of
the net proceeds to develop further our demand aggregation service, to acquire
or develop complementary products, services, technologies or businesses or to
make strategic investments. We currently have no present commitments or
agreements with respect to any such acquisitions or investments. Pending any of
these uses, we intend to invest the net proceeds in short-term, investment-
grade, interest-bearing securities.

                                DIVIDEND POLICY

   We have never declared or paid cash dividends on our capital stock. We
currently intend to retain all available funds and any future earnings for use
in the operations and expansion of our business and do not anticipate paying
any cash dividends in the foreseeable future. Payments of future dividends, if
any, will be at the discretion of our Board of Directors and will depend on our
results of operations, financial condition, contractual and legal restrictions
and other factors the Board of Directors deems relevant.

                                    DILUTION

   Our pro forma net tangible book value as of December 31, 1999 was
approximately $42.2 million or $1.43 per share. Pro forma net tangible book
value per share represents the amount of our total tangible assets reduced by
the amount of our total liabilities and divided by the total number of shares
of common stock outstanding after giving effect to the issuance of
2,522,250 shares of Series C preferred stock and the issuance in March 2000 of
a $10.0 million convertible note payable and the automatic conversion of all
shares of our preferred stock outstanding as of March 1, 2000 into common
stock. Dilution in pro forma net tangible book value per share represents the
difference between the amount per share paid by purchasers of shares of common
stock in this offering and the pro forma net tangible book value per share of
common stock immediately after the completion of this offering. After giving
effect to the sale of the shares of common stock offered by us at an assumed
initial public offering price of $   per share, and after deducting the
underwriting discounts and commissions and estimated offering expenses payable
by us, our pro forma net tangible book value at December 31, 1999 would have
been approximately $   million, or $   per share of common stock. This
represents an immediate increase in pro forma net tangible book value of $
per share to existing stockholders and an immediate dilution of $   per share
to new investors of common stock. The following table illustrates this dilution
on a per share basis:

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS

   The following discussion should be read in conjunction with the financial
statements and the notes to those statements included elsewhere in this
prospectus.

Overview

   We are a provider of Internet-based demand aggregation services that empower
buyers with common purchasing interests to achieve discounts on high-quality,
brand-name products and services. On Mercata.com, buyers can participate in
group buying through PowerBuy group purchases and can also purchase products at
fixed prices. For online businesses, we also offer an e-commerce solution,
known as the We-Commerce Network, that enables merchant, portal, community and
content Web sites to offer merchandise for sale using our proprietary business
methods and technology.

   We were incorporated in September 1998 and began offering products for sale
on our Web site in May 1999. For the period from inception through April 1999,
we had no revenues and our operating activities related primarily to developing
our proprietary business methods, technology and infrastructure. From the
launch of our Web site in May 1999 through December 31, 1999, we continued to
build our infrastructure and also focused on customer acquisition and
retention, the expansion of vendor relationships, the establishment of our
brands, the expansion of our fulfillment and customer service operations and
the development of the We-Commerce Network. Our operating expenses have
increased significantly since our inception due to costs associated with these
activities.

   To date, we have derived substantially all of our revenues from selling
products on Mercata.com. We currently sell merchandise using two pricing
structures: PowerBuy group purchases and Group Values. PowerBuy group purchases
are limited-time buying opportunities in which the price of the featured
product or service dynamically decreases, based on parameters determined by the
seller, as more visitors join the buying group. Customers join a PowerBuy by
entering an offer at the current PowerBuy price or, alternatively, by making a
conditional offer at a price below the current price. At the conclusion of a
Powerbuy, all customers whose offers equal or exceed the final price of the
featured item are shipped the item and charged the final PowerBuy price.
PowerBuy group purchases have a fixed duration and generally lasts
approximately two to three days. Group Values are products that have fixed
prices and can be purchased at any time.

   Due to the dynamic nature of the PowerBuy and the flexibility of our
proprietary PowerBuy management tools, we can optimize customer acquisition,
gross margins, net revenues or unit sales by adjusting the PowerBuy price to
meet predetermined goals. For example, we can maximize sales volume by reducing
the price during the PowerBuy to capture outstanding offers made below the
current price. Alternatively, we can maximize gross margin percentage by
limiting the level to which the PowerBuy price will drop. From time to time, we
sell merchandise below target margins and, on rare occasions, we sell products
below cost in order to acquire customers.

   Group Value products typically have higher gross margin percentages than
PowerBuys, since a large portion of Group Value products have Minimum
Advertised Price (MAP) restrictions placed on them by manufacturers. Products
placed on PowerBuy generally do not have such restrictions.

   In 1999, approximately 71% of all orders placed, in terms of total dollar
value, were generated through PowerBuy group purchases. During 1999, we filled
orders for approximately 72,000 customer accounts, and approximately 32% of all
orders placed, in terms of individual orders, came from repeat buyers.

                                       23
<PAGE>

   We primarily use two methods of distributing our products to our customers:
shipments made through distributors and shipments made through our third-party
fulfillment warehouse. In 1999, approximately 67% of our shipments, in terms of
net revenues, were fulfilled through distributors, and the remaining 33% were
fulfilled by our third-party warehouse. We do not incur any handling fees when
the products are sourced from a distributor, although we do incur shipping
costs. A nominal handling charge is incurred to store, pick, pack and ship
products from our third-party warehouse.

   To date, revenues derived from the We-Commerce Network have come exclusively
from the sale of merchandise to customers who have bought products through the
We-Commerce Network's co-branded stores. In exchange for this additional
traffic to the We-Commerce Network, we pay the participants a percentage of net
revenues or promotional fees. We intend to extend PowerBuy functionality to a
variety of merchants, product manufacturers, and portal, content and community
Web sites and intend to implement a new revenue-generating service with these
We-Commerce Network participants by charging up-front activation charges and
service and transaction fees.

   Since inception, we have incurred significant losses and, as of December 31,
1999, we had an accumulated deficit of approximately $38.0 million. We expect
to increase our operating expenses in order to enhance our brands, expand the
We-Commerce Network, increase our customer base, support our growing
infrastructure and introduce new products and services. Our revenues and gross
margins will need to increase significantly to cover these and other future
costs. We will need to generate and sustain substantially higher revenues in
order to become profitable.

   In connection with the grant of certain employee stock options with exercise
prices less than the deemed fair value of the underlying common stock for
financial reporting purposes, we recorded aggregate deferred stock-based
compensation of $3.3 million for the year ended December 31, 1999. This
deferred stock-based compensation is being amortized over vesting periods of
the options.

Composition of Income Statement Line Items

Net Revenues

   Net revenues consist of product sales to customers less allowances for sale
returns, and exclude promotional credits offered to first-time customers, such
as Mercata$ store credits. Promotional credits for first-time customers were
discontinued as of January 31, 2000.

Cost of Revenues

   Cost of revenues consists primarily of the cost of merchandise sold to
customers, inbound freight, handling charges at our third-party warehouse and
expedited shipping costs, net of expedited shipping revenues. Cost of revenues
excludes costs of merchandise associated with promotional credits used for new
customer purchases, such as Mercata$ store credits. These costs are included in
sales and marketing expense.

Operating Expenses

   Sales and Marketing. Sales and marketing expenses consist primarily of
advertising, public relations and third-party fulfillment fees, as well as
payroll and related expenses for personnel engaged in marketing, sales and
related activities. These expenses also include promotional expenditures, such
as free ground shipping and the cost of merchandise associated with promotional
credits used for new customer purchases.

                                       24
<PAGE>

   Technology and Development. Technology and development expenses consist
primarily of payroll and related expenses for development, Website design and
network operations, as well as systems infrastructure costs.

   General and Administrative. General and administrative expenses consist of
payroll and related expenses for executive, accounting and administrative
personnel, recruiting and professional fees, and other general corporate
expenses.

Interest Income (Expense), Net

   Interest income (expense), net consists of interest income from earnings on
our cash and cash equivalents, offset by interest expense paid on short-term
debt instruments.

Income Taxes

   We have had a net loss for each period since inception. As of December 31,
1999, we had approximately $35.8 million of net operating loss carryforwards
for federal income tax purposes, which expire in 2014. We have provided a full
valuation allowance on our net deferred tax assets, consisting primarily of net
operating loss carryforwards, because of uncertainty regarding their
realizability. See Note 9 of notes to financial statements.

Results of Operations

Period from September 23, 1998 (Inception) to December 31, 1998 and the Year
Ended December 31, 1999

Net Revenues

   We did not begin to sell products on Mercata.com until May 1999, and
therefore we did not record any net revenues in 1998. Net revenues in 1999 were
$6.3 million.

Cost of Revenues

   As we had no net revenues in 1998, there was no cost of revenues recorded in
that period. Cost of revenues in 1999 was $5.8 million.

Operating Expenses

   Sales and Marketing. Sales and marketing expenses increased from $498,000 in
1998 to $29.7 million in 1999, primarily due to the launch of our Web site in
May 1999 and the implementation of our brand and Web site awareness campaigns
during the second half of 1999. Advertising expenses totaled $0 in 1998 and
approximately $21.5 million in 1999. The cost of merchandise associated with
promotional discount programs used for new customer purchases was $2.4 million
in 1999. Advertising expenses, which totaled $17.6 million during the fourth
quarter of 1999, increased as a result of increased offline advertising costs.
We intend to continue our aggressive branding and marketing campaigns in the
foreseeable future. We anticipate sales and marketing expenses will decrease as
a percentage of net revenues throughout 2000, with a significant percentage of
the total annual expenditures occurring during the fourth quarter.

   Technology and Development. Technology and development expenses increased
from $664,000 in 1998 to $3.9 million in 1999. The increase in technology and
development expenses was attributable primarily to costs associated with
increasing staffing, building our Web site and expanding our systems
infrastructure. We believe that continued investment in technology and

                                       25
<PAGE>

development is critical to attaining our strategic objectives and, as a result,
we expect a steady growth of these expenditures during 2000.

   General and Administrative. General and administrative expenses increased
from $761,000 in 1998 to $3.5 million in 1999. The increase in general and
administrative expenses was due primarily to increased salaries and related
expenses associated with the hiring of personnel and increases in professional
fees and travel expenses. We expect general and administrative expenses to
decrease as a percentage of net revenues in 2000 as we continue to utilize
existing administrative infrastructure put in place during 1999.

Interest Income (Expense), Net

   Interest income (expense), net was ($12,000) in 1998, and $467,000 in 1999.
The increase in interest income (expense), net was due to the sale of Series A
and B preferred stock in 1999, which significantly increased our average
balance of cash and cash equivalents.

Quarterly Results of Operations

   The following table sets forth certain unaudited quarterly statement of
operations data for each of the last five quarters through December 31, 1999.
In the opinion of management, this information has been prepared substantially
on the same basis as the audited financial statements appearing elsewhere in
this prospectus, and all necessary adjustments, consisting only of normal
recurring adjustments, have been included in the amounts stated below to
present fairly the unaudited quarterly results. The quarterly data should be
read in conjunction with our audited financial statements and the notes to
those statements appearing elsewhere in this prospectus. The operating results
for any quarter are not necessarily good indications of future performance.

</TABLE>

   Our net revenues have increased significantly in the quarters following the
launch of our Web site in May 1999. Total operating expenses have increased
over the most recent three quarters, reflecting increased spending on
developing, delivering, supporting and marketing our business and products.
Sales and marketing expenses, in particular, significantly increased in the
fourth quarter of 1999. As a result of our limited operating history and the
emerging nature of the markets in which we compete, we are unable to forecast
accurately our revenues. Our current and future expense level estimates are
based largely on our investment plans and estimates of future revenues and are
largely discretionary, due to the high advertising component.

                                       26
<PAGE>

   We expect our online retail business to be highly seasonal, reflecting the
general pattern associated with the retail industry of peak sales and earnings
during the fourth quarter. We believe that a substantial portion of our annual
sales will occur in the fourth quarter of each year. We expect to experience
lower quarterly sales during the first three quarters of each fiscal year
relative to the fourth quarter, as is typical in the retail industry. As a
result, we may continue to incur greater losses in these quarters. See "Risk
Factors -- Our quarterly operating results vary significantly and may cause our
stock price to fluctuate".

   We funded our operations in 1998 through a private placement of common stock
in exchange for $400,000 and a series of short-term notes, totaling $3.6
million, in favor of Paul G. Allen. In March of 1999, we completed a Series A
preferred stock financing in the amount of $14.7 million with Vulcan Ventures
Incorporated, at which time the short-term notes were retired. In September and
October of 1999, we raised an additional $35.0 million by issuing Series B
preferred stock.

   Net cash used in operations in 1999 totaled $30.2 million, with the majority
of funds spent on marketing activities in the second half of the year.

   Net cash used in investing activities during 1999 was $3.8 million, which is
attributable primarily to the purchase of computer-related equipment and
software used to operate the Mercata.com Web site. Currently, we have no
material commitments for future capital expenditures, although we expect to
make purchases of capital equipment to accommodate the expected growth of our
business and the related increase in traffic to Mercata.com.

   Net cash provided by financing activities in 1999 totaled $47.0 million.
These funds were raised primarily through the sale of our Series A and Series B
preferred stock. In addition, in September 1999, we borrowed $2,000,000 under a
promissory note payable to a stockholder. The promissory note was payable on
demand and bore interest at the prime rate. The principal, plus accrued
interest of $9,945, was repaid in October 1999. We canceled the promissory note
in March 2000.

   In March 2000, we raised $40.0 million through the sale of our Series C
preferred stock and the issuance of a $10.0 million convertible note.

   We believe that the net proceeds of this offering, together with existing
cash and cash equivalents, will be sufficient to meet our operating and capital
requirements for at least the next 12 months. After that, we may need to raise
additional funds. We may seek to raise additional funds through additional
borrowings, public or private equity financings or from other sources. We
cannot assure you that additional financing will be available at all or, if
available, will be on terms acceptable to us.

Year 2000 Risk

   Many currently-installed computer system and software products are coded to
accept or recognize only two digit entries in the date code field. These
systems may recognize a date using "00" as the year 1900 rather than the year
2000. As a result, computer systems or software used by many companies and
governmental agencies may need to be upgraded to comply with Year 2000
requirements or risk system failure or miscalculations causing disruptions of
normal business activities.

   We expect most material Year 2000 problems to have arisen on or immediately
after January 1, 2000. As of March 1, 2000, we are not aware of any Year 2000
problems associated with our internal systems or software or with the software
and systems of our vendors, distributors or suppliers. It is possible, however,
that Year 2000 problems will occur in the future.

                                       27
<PAGE>

   Undetected Year 2000 problems in our systems may result in substantial
revisions or replacements. In the event that the fulfillment and operational
facilities that support our business, or our Web-hosting facilities, are not
Year 2000 compliant, we may be unable to deliver goods or services to our
customers and portions of our Web site may become inaccessible. In addition, we
cannot assure you that third-party software, hardware or services incorporated
into our material systems will not need to be revised or replaced, which could
be time-consuming and expensive. Our inability to fix or replace third-party
software, hardware or services on a timely basis could result in lost revenues,
increased operating costs and other business interruptions, any of which could
harm our business. Moreover, the failure to adequately address Year 2000
problems in our software, hardware or systems could result in claims of
mismanagement, misrepresentation or breach of contract and related litigation,
which could be costly and time-consuming to defend.

   In addition, we cannot assure you that governmental agencies, utility
companies, Internet service providers and other third parties outside our
control will be Year 2000 compliant. The failure by these parties to be Year
2000 compliant could result in a systemic failure beyond our control,
including, for example, a prolonged Internet, telecommunications or electrical
failure, which could prevent us from delivering our services to our customers,
prevent customers from accessing our services or decrease the use of the
Internet any of which would harm our business.

   If our present efforts to address potential Year 2000 problems are not
successful, or if distributors, suppliers and other third parties with which we
conduct business do not successfully address such issues, our customers could
seek alternate suppliers of our products and services. Any material Year 2000
problem could require us to incur significant unanticipated expenses to remedy
the problem and could divert our management's time and attention, either of
which could harm our business.

Recently Issued Accounting Pronouncements

   The Financial Accounting Standards Board issued Statement of Financial
Accounting Standards (SFAS) No. 133, "Accounting for Derivative Instruments and
Hedging Activities", in June 1998. SFAS No. 133 establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts, and for hedging activities. It
requires that an entity recognize all derivatives as either assets or
liabilities in the balance sheet and measure those instruments at fair value.
If certain conditions are met, a derivative may be specifically designated as a
hedge. The accounting for changes in the fair value of a derivative depends on
the intended use of the derivative and the resulting designation. SFAS No. 133,
as amended by SFAS No. 137, "Accounting for Derivative Instruments and Hedging
Activities--Deferral of the Effective Date of FASB Statement No. 133", is
effective for all fiscal quarters of fiscal years beginning after June 15,
2000. The adoption of this statement is not expected to have a material impact
on our financial statements.

   In December 1999, the United States Securities and Exchange Commission (SEC)
released Staff Accounting Bulletin (SAB) No. 101 "Revenue Recognition in
Financial Statements", which must be applied in our first fiscal quarter of
2000. SAB No. 101 provides guidance on revenue recognition and the SEC staff's
views on the application of accounting principles to selected revenue
recognition issues. We do not expect that the adoption of SAB No. 101 will have
a material effect on our financial statements.

   In October 1999, the SEC identified a list of issues that have arisen in
Internet businesses which the SEC believes should be addressed by the Emerging
Issues Task Force (EITF) of the FASB or other standard setting bodies. While
the EITF is in the process of addressing such issues, many of the identified
issues have not yet been resolved. Future resolution of all of the issues
identified by the SEC may affect our financial statements. We are not able to
determine the impact on our financial statements, if any, of such future rule
making.

Market Risk

   We currently market our products in the United States and Canada. As all
sales are currently made in U.S. dollars, we do not believe we are exposed to
currency risk with respect to our sales. As of December 31, 1999, we had cash
and cash equivalents of $13.9 million consisting of cash and highly liquid,
short-term investments. Our short-term investments will decline by an
immaterial amount if market interest rates increase, and therefore, our
exposure to interest rate changes presently is not significant. Decline of
interest rates over time, on the other hand, will reduce our interest income
from our short-term investments.

                                    BUSINESS

Mercata(TM)

   We are a provider of Internet-based demand aggregation services. Our
business model empowers buyers with common purchasing interests to achieve
discounts on high-quality, brand-name products and services. Demand aggregation
operates on two basic principles: (1) sellers are more likely to offer
discounts to buyers when merchandise is purchased in volume and (2) buyers are
more likely to purchase merchandise as prices decrease. We call our Internet-
based form of demand aggregation "We-Commerce(TM)". On our Mercata.com Web
site, buyers participate in group buying through PowerBuy(TM) group purchases.
PowerBuys are limited-time buying opportunities in which the price of the
featured product or service dynamically decreases, based on parameters
determined by the seller, as more visitors join the buying group.

   Through the use of our proprietary business methods and technology,
individual buyers are able to combine their purchasing power to receive volume
pricing benefits on featured merchandise. Using this same technology, a seller
may gain access to actual buyer demand and price sensitivity data, enabling the
seller to adjust prices during a PowerBuy in order to achieve sales objectives,
such as increasing units sold, revenues, gross profit dollars or gross margin
percentage.

   For online businesses, we offer an e-commerce solution through the We-
Commerce Network. Currently, the We-Commerce Network has two principal types of
participants:

  .  merchants that desire to sell their products and services on their Web
     sites using a dynamic pricing mechanism and extend the reach of their
     merchandise offerings to other Web sites; and

  .  portal, community and content Web sites that desire to enhance their e-
     commerce capabilities by providing users a novel buying experience.

   Within this network of online businesses, PowerBuy group purchases can be
conducted simultaneously on multiple Web sites, thus potentially increasing the
number of individual buyers within any given PowerBuy. To date, participants in
the We-Commerce Network include DealTime.com, Inc., Football Northwest LLC
(Seahawks.com), Go2Net, Inc., Mercata.com, the Microsoft Network LLC (MSN),
mybytes.com (a division of Youthstream Media Networks, Inc.), Online Office
Supplies Company and SAVIshopper.com, Inc.

   We were incorporated in September 1998 and began to offer products for sale
on Mercata.com in May 1999. In the fiscal year ended December 31, 1999, we
generated net revenues of $6.3 million and received orders from over 72,000
customer accounts.

Industry Overview

Growth of the Internet

   The Internet has emerged as a significant interactive medium for conducting
business. International Data Corporation estimates that the number of users
worldwide will increase from 196 million in 1999 to 502 million in 2003. IDC
also estimates that business-to-consumer e-commerce will rise from $31.2
billion in 1999 to $171 billion in 2003, and business-to-business e-commerce
will rise from $64.6 billion in 1999 to $974 billion in 2003, representing the
widespread commercial adoption of the Internet by both consumers and
businesses.

   The Internet possesses a number of unique and commercially powerful
characteristics that differentiate it from traditional media: users communicate
without geographic limitation, have access to dynamic and interactive content
on a real-time basis and transact business virtually instantaneously at little
or no incremental cost. The Internet has created a dynamic and attractive
medium for commerce, enabling real-time communication between buyers and
sellers, greater

                                       30
<PAGE>

access to comparative purchasing data and the ability to shop in ways perceived
as more convenient. As the Internet has become more accessible and widely used
for transactions, new and diverse business models for online commerce have
emerged and are gaining rapid market acceptance.

Limitations of Traditional Retail Formats and Pricing Methods

   Competition among retailers often is based principally on product selection
and price. In order to offer the broadest selection at the lowest price,
retailers must have purchasing economies of scale and effective inventory
management; however, the process of forecasting consumer demand and predicting
inventory needs accurately can be inefficient and costly for a traditional
retailer. We believe traditional retail pricing methods, where sellers
typically market products to consumers at fixed retail prices, have significant
disadvantages for both sellers and consumers. For example, sellers are unable
to take fully into account the price sensitivity of potential buyers before
setting prices. In addition, sellers who later reduce prices to clear excess
inventory risk disruption of their existing distribution channels. Individual
buyers, on the other hand, often are required to pay more for fixed-price
products because they lack sufficient bargaining power to negotiate more
favorable pricing terms.

   The membership warehouse club and traditional buyers' cooperative business
models address some of the problems associated with traditional retail formats
and pricing methods. Membership warehouse clubs are based, in part, on the
concept that offering consumers and small businesses low prices on a limited
selection of nationally branded and private label products in a wide range of
merchandise categories will produce high sales volumes and rapid inventory
turnover. We believe this turnover, when combined with the operating
efficiencies achieved by volume purchasing, efficient distribution and reduced
handling of merchandise, enables membership warehouse clubs to maintain their
profitability while offering low prices to consumers. From the buyers'
perspective, however, this format can be perceived as an inconvenient
alternative because individual purchasers often must buy in large quantities in
order to enjoy significant discounts. Traditional buyers' cooperatives
aggregate buyers to purchase products and services in bulk, typically resulting
in lower per unit costs. However, the range of products and services that could
be purchased through cooperatives historically has been limited, and the
logistics of assembling large groups of buyers with similar interests has
hindered the wide-spread adoption of this group buying model for routine
commercial transactions.

Convergence of the Internet With Traditional Retail Formats and Pricing Methods

   With the emergence of the Internet, some companies have adapted traditional
pricing methods to online commerce, while others have created entirely new
selling formats designed to take advantage of the unique attributes of the
Internet. For example, Internet-based auctions are not limited by geography and
the logistical challenge of bringing buyers and sellers together. New
electronic commerce formats have been employed by other online businesses to
allow buyers to participate in "name your price" transactions where sellers can
accept or reject buyers' bids on an individual basis. The interactive, real-
time and far-reaching nature of the Internet has allowed these models to
achieve rapid acceptance. Nevertheless, we believe these retail formats and
pricing methods have not recognized the commercial potential of aggregating
buyer demand on the Internet. We believe that the convergence of the Internet
and group buying methods represents a significant opportunity to create a
commercial format that provides benefits to both buyers and sellers.

The Mercata Business Model

   We have developed a novel Internet-based group buying service, based upon a
demand aggregation business model, that empowers buyers with common purchasing
interests to achieve

                                       31
<PAGE>

discounts on high-quality, brand-name products and services. Demand aggregation
operates on two basic principles: (1) sellers are more likely to offer
discounts to buyers when merchandise is purchased in volume and (2) buyers are
more likely to purchase merchandise as prices decrease. Whereas the traditional
retail approach requires sellers to hold inventory, stock products and set
prices in advance, our technology provides them access to actual buyer demand
data in order to reduce the risk associated with forecasting inventory needs
and buyer price sensitivity. Our approach also allows sellers to offer
increasing discounts to buyers during the course of a group buying opportunity.
We call our Internet-based form of demand aggregation "We-Commerce".

  We offer buyers the opportunity to participate in group buying through
PowerBuy group purchases. PowerBuys are limited-time buying opportunities in
which the price of the featured product or service dynamically decreases, based
on parameters determined by the seller, as more visitors join the buying group.
Buyers can participate in PowerBuy group purchase opportunities on Mercata.com
and throughout the We-Commerce Network. The We-Commerce Network is an
e-commerce solution for online businesses designed to enable merchant, portal,
community and content Web sites to offer merchandise for sale using our
proprietary business methods and technology.

   Our business model delivers value to both buyers and sellers by matching
buyers' demands with sellers' objectives. We believe that the principal
advantages of our model include:

   Cost Savings and Empowerment for Buyers. By bringing together buyers with
similar purchasing interests, we enable them to aggregate their purchasing
power to receive volume pricing benefits. Through PowerBuy group purchases, in
which an increasing number of buyers can influence prices dynamically, we
deliver cost savings to individual buyers on high-quality, brand-name products
and services, without requiring them to make purchases in bulk. We believe our
model empowers buyers and offers them a rewarding and exciting buying
experience.

   Interactive Buyer Community and Information Sharing. Visitors to Mercata.com
and to other We-Commerce Network participants' Web sites communicate through
PowerTalk message boards associated with each PowerBuy group purchase and
through our Share the Power(TM) e-mail referral features. On the PowerTalk
message boards, visitors share information relevant to specific products, meet
others with common purchasing interests and potentially influence group buying
decisions. Through our Share the Power e-mail referral features, visitors to
Mercata.com send messages to others who may be interested in an offered product
or our group buying experience. The PowerTalk and Share the Power features are
important customer acquisition tools because buyers are motivated to encourage
participation by others in group buying opportunities in order to receive
greater pricing benefits.

   Dynamic Yield Management for Sellers. Our proprietary business methods and
technology are designed to provide sellers with information on buyers' product
preferences and price sensitivities. Our group buying model provides a seller
access to information on all offers made by buyers for products offered by the
seller, including those below current PowerBuy prices. Based on the unique
demand profile for specific products, prices may be adjusted dynamically to
optimize a PowerBuy to meet sellers' goals. For example, if the number of
prospective buyers who have made offers below the current PowerBuy price is
large, the price may be reduced in order to maximize customer acquisition,
sales volume or absolute gross profit dollars. Alternatively, sellers may
choose to optimize gross margin percentage by limiting the level to which the
PowerBuy price can drop.

   Novel Distribution Channel. Our retail format creates a new channel for
sellers to distribute efficiently large volumes of products, to liquidate
products and to test market new products. Using our channel to sell large
volumes of products, sellers can adjust pricing in real-time to maximize sales
volume or other factors. Using our channel to liquidate products, sellers can
avoid disrupting their

                                       32
<PAGE>

existing distribution channels. Using our channel to test new products, sellers
can gather real-time data on buyer responses to changes in price. In addition,
sellers are able to obtain the preference information and related data of
participants in a PowerBuy, regardless of whether their offers result in sales.

Our Strategy

   Our goal is to be the world's leading provider of Internet-based demand
aggregation services. Key elements of our strategy are to:

   Continue to Build our Mercata.com Customer Base. We intend to increase the
number of buyers who purchase products and services on Mercata.com. To
accomplish this goal, we plan to provide buyers with significant cost savings,
broad selection, responsive customer service, reliable fulfillment and an
enjoyable buying experience. In addition, we intend to establish, maintain and
strengthen relationships with new and existing manufacturers and distributors
to increase the breadth and depth of products and services we offer to our
customers. We also will continue to advertise the Mercata brands aggressively
through both offline and online media and to focus on building strong, lasting
customer relationships in order to drive repeat purchases and high average
order sizes.

   Continue to Build the We-Commerce Network. We intend to expand the We-
Commerce Network to include a larger number of merchant, portal, community and
content Web sites. We plan to offer these businesses group buying solutions
using We-Commerce business methods and technology to offer products and
services directly to their visitors. By assembling this collection of online
businesses, we expect that our ability to aggregate buyers within any given
PowerBuy will increase.

   Penetrate the Business-to-Business Market. We intend to take advantage of
our demand aggregation expertise, our experience in the business-to-consumer
market and the existing awareness of our brands to penetrate the business-to-
business market. We believe the business-to-business market is well-suited to
take advantage of our demand aggregation services, and could represent
substantial gross sales and transaction revenues for us. We will explore
opportunities to work cooperatively with existing online and offline companies
that focus on providing products and services to small businesses. We intend to
expand our presence in this market through targeted sales and marketing
efforts, the expansion of the We-Commerce Network and enhanced service
offerings.

   Continue to Expand Technology and Broaden Communication Channels. We intend
to continue to expand our technology to add functions and features to
Mercata.com and the We-Commerce Network. We also intend to take advantage of
new means of electronic communication and distribution to bring increasingly
larger buying groups together quickly and easily. We currently are developing
software to enable wireless communication with our customers, and we also plan
to extend our business methods and technology to position ourselves for the
migration of e-commerce to broadband environments. We believe the use of
higher-speed wired and wireless technologies, including interactive cable
television, digital subscriber line (DSL), personal digital assistant (PDA) and
satellite and cellular technologies will further enhance our customer group
buying experience.

The Mercata.com Experience

   We believe we provide a rewarding and exciting customer buying experience at
Mercata.com. We offer over 300 brands across the following product categories:
appliances, baby products, electronics, gifts and gadgets, home and kitchen
items, lawn and garden products, luggage, sporting goods, tools, and watches
and jewelry. Mercata.com enables users to navigate easily and purchase from a
wide selection of items -- many of which are featured as PowerBuy group
purchases.

                                       33
<PAGE>

Mercata.com offers visitors helpful features such as search functions, buyer's
guides, customer message boards and the ability to browse and shop by consumer
brands.

   Browsing. Mercata.com offers visitors an easy-to-use format intended to
enhance the product search, selection and discovery process. Visitors have the
ability to search by brands, pre-defined categories, keywords, and PowerBuy
closing dates. In addition to the search engines, at the top of every shopping
page the dynamically generated "Powerbuy Ticker" prominently displays high-
profile PowerBuys, their current PowerBuy prices, and the amount the price has
dropped since the start of the PowerBuy.

   Product Research. In our Smart Shopper area visitors can learn details
regarding key product features and specifications, obtain answers to frequently
asked questions, view lists of glossary terms and more. Visitors may select and
compare up to four different products that currently are offered on Mercata.com
based on price and other specifications. Visitors may also view rebates by
product brand, print coupons or coupon summaries and view the brands currently
offered on our Web site.

   PowerBuy Group Purchases. Customers join a PowerBuy by entering an offer at
the current PowerBuy price, or, alternatively, by making a conditional offer at
a price below the current price. At the conclusion of the PowerBuy, all
customers whose offers equal or exceed the final price of the PowerBuy are
shipped the product and charged the final PowerBuy price. PowerBuy group
purchases have a fixed duration and generally last approximately two to three
days.

   Interactive Community Features. The use of our Share the Power e-mail
referral features is an important part of our cost-effective, word-of-mouth
customer acquisition strategy. Our registered users can send Share the Power e-
mails to potential buyers with pre-scripted messages detailing specific
PowerBuys. In addition, users may also send e-mail messages containing general
introductory information regarding Mercata. If the recipients of these general
introductory e-mails make a purchase at Mercata.com, the sender is given a
Mercata$ store credit. Users also can encourage others to participate in
specific PowerBuy group purchases by posting messages on our PowerTalk message
boards. Users are motivated to use these features because an increasing number
of buyers in each PowerBuy generally lowers the price of the featured item.

   Mercata$ store credits. Visitors to our Web site receive Mercata$ store
credits on select product purchases and by referring others to Mercata.com
through our Share the Power e-mail referral program. Mercata$ store credits can
be redeemed to receive a discount of up to 50% off future purchases.

   Group Value Products. Group Value products have fixed prices and can be
purchased at any time. These products expand our selection and offer customers
the opportunity to purchase products immediately.

   Product Requests. Visitors can notify us of products and brands they are
interested in purchasing through the Product Request feature on Mercata.com. We
actively review these requests and attempt to respond to these suggestions by
sourcing products, as appropriate, and offering them for sale on our Web site.

   Customer Service. Customers can visit Mercata.com to manage their own
personal account information, including credit card, shipping and profile data.
Customers can also use our Web site to track the progress of PowerBuy group
purchases and the status of orders, review their account history, view details
on all past transactions and track Mercata$ store credits that have been earned
and spent. In addition, we provide a toll-free number and e-mail access to
allow customers to contact our customer support and service personnel.

                                       34

The We-Commerce Network

   In addition to Mercata.com, we offer demand aggregation services to online
businesses to enable them to offer We-Commerce business methods and technology
to their customers. The We-Commerce Network currently consists of merchant,
portal, community and content Web sites, including DealTime.com, Inc., Football
Northwest LLC (Seahawks.com), Go2Net, Inc. Mercata.com, the Microsoft Network
LLC (MSN), mybytes.com (a division of Youthstream Media Networks Inc.), Online
Office Supplies Company and SAVIshopper, Inc. We are dedicating significant
resources to expand the network and expect to add other participants, including
selected manufacturers and other online merchants. By assembling this
collection of online businesses, we expect our ability to aggregate buyers
within any given PowerBuy will increase. Through the We-Commerce Network, we
are able to extend further our proprietary business methods and technology and
accelerate the growth of group buying on the Internet.

   We offer merchants the ability to provide PowerBuy group purchases to their
customers. We will create and manage PowerBuy group purchases for these
merchants as a service and expect to earn account set-up, management and
transaction fees based on the volume of sales derived from these PowerBuy group
purchases. We believe online merchants will benefit from the addition of a
novel pricing format and from an efficient direct channel to large groups of
buyers.

   As a participant in the We-Commerce Network, portal, community and content
Web sites can offer their visitors the ability to participate in a variety of
PowerBuy group purchases in either co-branded or private label formats. This
feature is designed to encourage repeat visits and increase the likelihood that
visitors will spend more time on their sites. In the future, Internet portals
may also receive fees from other We-Commerce Network participants for directing
visitor traffic to such participants' PowerBuy merchandise.

Product Merchandising and Sourcing

   Our merchandising strategy is to provide a broad assortment of high-quality,
brand-name products at competitive prices. Top selling brands in our highest
revenue generating product categories include Bushnell, Graco, Krups,
Leatherman, Makita, Phillips and Sharp. To encourage product purchases, we
feature various promotions on a rotating basis and regularly update our
PowerBuy specials. The primary factors that we consider when deciding to offer
a product as a PowerBuy are buyer demand, the need to move large volumes of
product quickly, our agreements with manufacturers and distributors of the
product, the desire of a particular supplier to test price sensitivity, and the
price at which we can purchase the product. We create and maintain Web pages
that are designed to highlight certain product brands we sell in our different
departments. We believe this strategy provides us with an excellent opportunity
to cross-sell a brand across our departments and promote impulse purchases by
customers.

   We believe that the breadth and depth of our product selection, together
with the flexibility of our PowerBuy pricing mechanism and our range of
shopping services, enable us to pursue an effective merchandising strategy.
Mercata.com features a large selection of products in the following categories:
appliances, baby products, electronics, gifts and gadgets, home and kitchen
items, lawn and garden products, luggage, sporting goods, tools, and watches
and jewelry. In cooperation with our product vendors, we have developed
detailed and helpful descriptions and comparative charts for many of the
products offered. Unlike store-based retail formats, Mercata.com provides us
significant flexibility with regard to the organization and presentation of our
product selection. In addition, our online format enables us to adjust our
product mix dynamically to respond to changing customer demand.

   We source products through our direct relationships with distributors and
manufacturers. Our in-house merchandise buyers are responsible for identifying
new products to offer, establishing new

                                       35
<PAGE>

supplier relationships, managing existing supplier relationships, negotiating
product costs and setting product prices. These buyers also analyze current
buying trends by maintaining close relationships with our suppliers, monitoring
sales at competing Web sites and studying Mercata.com traffic data. As an
authorized reseller of substantially all of the products currently offered on
Mercata.com, we have access to manufacturer information relating to warranties,
return policies and other technical or product-specific data and, more
importantly, we can offer products to which other unauthorized resellers may
not have access.

Marketing and Promotion

   We rely on offline and online marketing programs and promotional activities
to generate market awareness and build our brands. Our offline efforts include
traditional media, such as print, radio, outdoor and television advertising.
For example, we launched our "Down is Good" television and radio advertising
campaign in 12 cities in November 1999. In addition, we participate in public
relations activities and attend industry trade shows and conferences to raise
awareness of our brands. To augment our offline efforts, we advertise
Mercata.com on third-party Web sites and have established e-mail direct
marketing and online affiliate programs. We also rely on our customer and
manufacturer relationships to drive traffic to Mercata.com. We believe many of
our customers actively encourage others to come to our Web site and to
participate in PowerBuy group purchases. Registered users of Mercata.com can
reach out to other potential customers through Share the Power e-mails located
on each PowerBuy product page. They also may benefit from Share the Power
promotions where they earn product discounts when they refer customers to
Mercata.com. We benefit significantly from this word-of-mouth marketing and
expect to continue to promote our brands and our service indirectly through our
customers. In addition, we rely on links from manufacturers to Mercata.com and
referrals from our We-Commerce Network participants to drive traffic to our Web
site.

Operations, Fulfillment and Shipping

   We obtain the products we sell on Mercata.com through our relationships with
over 300 manufacturers and distributors. We requisition these products on a
purchase order basis. We currently use two primary methods of distributing
products to our customers:

   Via Distributors. We have relationships with seven distributors who reserve
inventory to be made available for sale on Mercata.com. We submit completed
order information to these suppliers, and they ship the product directly to the
customer using our Mercata packing slip. In 1999, approximately 67% of our net
revenues resulted from sales of products shipped using this method.

   Via Our Third-Party Warehouse. We also purchase inventory that we hold at a
third-party distribution center for processing, packaging and shipping to
customers. Because we own the products held in our third-party warehouse, we
are subject to inventory risk on products distributed using this method.
Because some manufacturers do not have direct distribution capabilities, having
our third-party warehouse allows us to offer a broader range of products on
Mercata.com. In 1999, approximately 33% of our net revenues resulted from sales
of products shipped using this method.

   The shipment of products directly from our distributors to our customers
reduces the level of inventory we are required to carry. Products purchased on
Mercata.com generally are shipped to customers within two business days of
acceptance of the final order. In 1999, over 90% of products ordered were
shipped within one business day and approximately 95% were shipped within
two business days. Because we reserve or purchase merchandise inventory in
advance, and because we can close a PowerBuy if a product sells out early,
generally 1% of customer orders are on back order status at any given time.

                                       36

   We use technology, whenever feasible, to optimize the exchange of
information between Mercata and our fulfillment partners, so that we can
properly set customer expectations about product availability and delivery
dates. Our operations team works with our partners and third-party warehouse to
manage and monitor order accuracy, fulfillment rate, shipment speed and overall
delivery reliability and timeliness. We measure product availability and
performance through daily reports and periodic on-site visits with partners and
our fulfillment warehouse.

   To date, we have offered free ground shipping to customers within the
continental United States and Canada via United Parcel Service (UPS) and the
United States Postal Service. Expedited shipping is available to customers via
UPS for an additional charge. We also offer our customers "white glove"
delivery on large and heavy items, such as big screen televisions, through our
agreement with Residential Delivery Services. This service provides scheduled
home or office delivery of the product, and removal of packaging materials.

Customer Service and Support

   We believe that a high level of customer service and support is critical to
retaining and expanding our customer base. Mercata.com is designed to answer
many questions customers might have in selecting, ordering or returning
products. In addition, we currently offer e-mail and toll-free telephone
service and support to our customers. Our customer service center is open
Monday -- Friday, 6:00 a.m. to 10:00 p.m. (Pacific Time) and Saturday --
 Sunday, 9:00 a.m. to 3:00 p.m. (Pacific Time) to provide assistance via e-mail
or telephone. We strive to answer all customer inquiries within 24 hours.
Mercata.com also contains a customer service page that outlines store policies
and provides answers to frequently asked questions. In addition, we currently
are implementing "live chat" technology on Mercata.com which will allow
customers to contact a customer service representative via an interactive
computer chat system. We manage our customer service center to provide prompt
and responsive customer communications and augment our customer service
personnel with customer and e-mail management systems from third-party vendors.
Our customer service representatives are trained to answer questions about
products and orders, assist customers in finding desired products and handle
any product returns. We accept returns within thirty days after a product has
shipped. After thirty days, customers are encouraged to utilize their
manufacturer's warranty for any product specific issues.

Technology

   Our proprietary We-Commerce business methods and technology are a
significant component of Mercata.com and the We-Commerce Network. We have built
a suite of server-based software components and PowerBuy management and pricing
tools that allow us to set up, initiate, monitor and manage PowerBuys for
varying products and services and for different durations. The We-Commerce
software also enables inventory checks with our third-party distribution
facility to determine the availability of products.

   To support our We-Commerce systems, we have licensed a broad array of
software from third-party vendors. Our system hardware is hosted at Exodus
Communications, Inc., a third-party data center in Tukwila, Washington, which
provides redundant communications lines and emergency power backup. We have
also implemented load-balancing systems to provide for high levels of
availability. System security is managed by both internal staff as well as
security staff at our third-party data center.

   Currently we are developing software to enable buyers to browse and make
purchases on Mercata.com using advanced cellular phones and wireless handheld
PDAs and are also designing systems to send notifications to wireless devices
about PowerBuy product offerings. We anticipate that these and other
communications technologies will be implemented in the future to further
increase the accessibility and functionality of Mercata.com and the We-Commerce
Network.

Competition

   The online commerce market is new, rapidly evolving and intensely
competitive. We expect competition to intensify in the future because current
and new competitors can enter our market and launch new Web sites or services
at a relatively low cost. For example, Yahoo! Inc. recently announced that it
will be entering the group buying market in the second half of 2000 and America
Online, Inc. announced it will do so in the first quarter of 2000. Increased
competition is likely to result in price reductions, reduced gross margins and
loss of market share, any of which could seriously harm our net sales and
results of operations.

   We currently or potentially compete with a variety of other companies,
including:

  .  other group buying services such as Accompany, Inc. and Letsbuyit.com,
     NV;

  .  Internet portals such as America Online, Inc. and Yahoo! Inc.

  .  online retailers such as 800.com, Inc., Amazon.com, Inc., Buy.com, Inc.
     and Priceline.com;

  .  providers of e-commerce services or functionality such as Fairmarket,
     Inc., Freemarkets, Inc., MySimon Inc. and Inktomi Corporation;

  .  business-to-business sellers such as Onvia.com, Inc. and Staples, Inc.;
     and

  .  traditional brick and mortar retailers such as Circuit City Stores,
     Inc., Costco Wholesale Corporation and Wal-Mart Stores, Inc.

   We believe Mercata.com competes in the online retail marketplace primarily
on the basis of price, recognition of the brands we offer, the breadth of our
product offerings, the amount of product information provided to customers and
convenience of shopping experience. Particularly with online retailers, we
compete on the basis of speed and accessibility of our Web site, quality of
site content, customer service and reliability, speed of order shipment and
price.

   Many of our online and traditional store-based competitors have longer
operating histories, larger customer or user bases, greater brand recognition
and significantly greater financial, marketing and other resources than we.
Many of these competitors also can devote substantially more resources to Web
site and systems development and may be better able to leverage customer bases
and supplier and other relationships. In addition, large well-established or
well-financed entities may join with online competitors or other companies, as
the use of the Internet and other online services increases.

   Our competitors may be able to secure products from vendors on more
favorable terms, fulfill customer orders more efficiently, adopt more
aggressive pricing or inventory availability policies and attract more clients
for their e-commerce services than we. Traditional store-based retailers also
enable customers to see and feel products in a manner that is not possible over
the Internet. Our online competitors may also adopt new technologies or methods
that have greater performance and features than ours. We also may face
additional competition as we expand our product and service offerings into new
categories. Additionally, new technologies and the expansion of existing
technologies, such as price comparison programs, may increase competition.
Dealing with these competitors may require significant additional expenditures
and could affect our business results of operations and financial condition. We
cannot be sure that we will be able to compete successfully against these
competitors.

Intellectual Property

   We currently have 11 United States and international patent applications. We
are in the process of filing one additional patent application, with ongoing
efforts to identify and protect new inventions.

                                       38
<PAGE>

Our pending patent applications relate to our novel demand aggregation business
methods and technology. Some of the patent applications also cover various
aspects of our PowerBuy management and pricing tools, and the expansion of
demand aggregation through the We-Commerce Network.

   While we believe that our pending patents ultimately will help to protect
our business, we cannot assure you that any of these pending patents will
issue, that any issued patents will protect our intellectual property or that
any issued patents will not be challenged by third parties. In addition, other
parties may independently develop similar or competing business methods or
technologies not covered by any patents that may issue to us.

   We currently are aware of several group buying Web sites that appear to use
a group buying business model. It is possible that we may enter into
arrangements with the operators of these sites to license our proprietary
business methods and technologies to them.

   We seek to protect our copyrights, service marks, trademarks, trade dress
and trade secrets through a combination of laws and contractual restrictions,
such as confidentiality agreements. For example, we attempt to register our
core trademarks and service marks in the United States and internationally.
However, effective trademark, service mark, copyright and trade secret
protection may not be available.

   We currently own over 50 Internet domain names, including "Mercata.com".
Domain names generally are regulated by Internet regulatory bodies. The
relationship between regulations governing domain names and laws protecting
trademarks and similar proprietary rights is unclear. We may be unable to
prevent third parties from acquiring domain names that infringe or otherwise
decrease the value of our trademarks and other proprietary rights.

Government Regulation

   Due to the increasing popularity and use of the Internet, a number of laws
and regulations may be adopted with respect to the Internet covering issues
such as user privacy, freedom of expression, pricing, content and quality of
products and services, taxation, financial reporting, advertising, intellectual
property rights and information security. The nature of these laws and
regulations and the manner in which they may be interpreted and enforced cannot
be fully determined and, therefore, these laws and regulations could subject us
to potential liability, which in turn could harm our business. The adoption of
any such laws or regulations might also decrease the rate of growth of Internet
use, which in turn could decrease the demand for our products and services, or
increase the cost of doing business, or otherwise harm our business. In
addition, applicability to the Internet of existing laws governing issues such
as property ownership, copyrights and other intellectual property issues,
taxation, libel, obscenity and personal privacy is uncertain. The vast majority
of these laws were adopted prior to the advent of the Internet and related
technologies and, as a result, do not contemplate or address the unique issues
of electronic commerce.

   All of our services are subject to federal and state consumer protection
laws and regulations prohibiting unfair and deceptive trade practices. We are
also subject to related "plain language" statutes in place in many
jurisdictions, which require the use of simple, easy-to-read terms and
conditions in contracts with consumers.

   We intend to explore opportunities for expanding our business into
international markets. It is possible, however, that our group buying business
model will not be readily adaptable to regulatory environments of certain
foreign jurisdictions. In addition, there are various other risks associated
with international expansion. They include local distribution monopolies,
language barriers, unexpected changes in regulatory requirements, trade
barriers, problems in staffing and operating foreign

                                       39
<PAGE>

operations, changes in currency exchange rates, difficulties in enforcing
contracts and other legal rights and economic and political instability.

   In addition, because our products and services are accessible throughout the
United States, other jurisdictions may claim that we are required to qualify to
do business as a foreign corporation in a particular state. We are qualified to
do business in Washington State and Pennsylvania. Our failure to qualify in a
jurisdiction where we are required to do so could subject us to taxes and
penalties for the failure to qualify and could result in our inability to
enforce contracts in those jurisdictions. Any new law or regulation relating to
the qualification to do business, or the application of laws or regulations
from jurisdictions whose laws do not currently apply to our business, could
harm our business, financial condition or results of operations.

Employees

   As of December 31, 1999, we had 104 employees, including 13 in customer
service, 12 in customer acquisition and retention, 33 in engineering, program
management and Web site design, five in operations, 24 in merchandising and 17
in executive management and administration. We devote, and will continue to
devote, substantial resources to attract high-quality employees; however, in
light of the tight labor market in which we operate, we cannot assure you we
will be successful in doing so. None of our employees is represented by a labor
union. We have not experienced any work stoppages and consider our employee
relations to be good.

Facilities

   Our corporate offices are located in Bellevue, Washington, where we lease
approximately 21,206 square feet under a lease and multiple subleases. We
currently are in the process of relocating our corporate offices. Under several
lease and sublease arrangements, we have the right to occupy up to 72,150
square feet of office space in Bellevue beginning in March 2000. The terms for
these leases and subleases range from two to approximately five years. When we
occupy all of this additional space, we anticipate our total annual lease
payments will be approximately $2.0 million. We expect that these facilities
will be adequate for our needs for the next 12 months.

Legal Proceedings

   From time to time, we may be involved in litigation relating to claims
arising out of our ordinary course of business. As of March 1, 2000, there are
no claims or actions pending or threatened against us, the ultimate disposition
of which would have a materially adverse effect on us.

of other antitakeover provisions found in our Certificate of Incorporation.

Board Committees

   Our Board of Directors has an Audit Committee, a Compensation Committee and
an Option Committee. The Audit Committee meets with our independent auditors at
least annually to review the results of the annual audit. The Audit Committee
also studies, reviews and evaluates our accounting, auditing and reporting
practices, including audit and control functions; serves as a focal point for
communication between non-committee directors, the independent accountants and
our management; and monitors transactions between us and our employees,
officers and members of the Board, or any of their affiliates. The Compensation
Committee sets, reviews and approves the compensation levels of and policies
for officers and employees; proposes the adoption, amendment and termination of
employee benefit plans; prepares a report of our compensation policies for our
proxy or information statements; and establishes guidelines for administration
of our 1999 Equity Incentive Plan, our 2000 Equity Incentive Plan and our 2000
Employee Stock Purchase Plan. The Option Committee proposes adoption, amendment
and termination of our equity incentive plans to the Board and grants options
to employees, other than executive officers, under such plans. The Audit and
Compensation Committees are each composed of three independent directors,
Ms. Levinson, Dr. Master and Mr. Nova, and the Option Committee is composed of
one director, Mr. Van Horn.

Compensation Committee Interlocks and Insider Participation

   No interlocking relationship exists between our Board of Directors or
Compensation Committee and the Board of Directors or Compensation Committee of
any other company, nor has such an interlocking relationship existed in the
past.

Board Compensation

   We do not currently provide our directors with cash compensation for their
services as members of the Board of Directors, although members are reimbursed
for reasonable expenses incurred in connection with attendance at Board and
committee meetings. Directors are eligible to participate in our stock plans,
and after the closing of this offering, each non-employee director will receive
an option to purchase 40,000 shares of our common stock as compensation for his
or her services. Current non-employee directors will each receive this grant
upon the closing of this offering, and each future non-employee director will
receive this grant at the time he or she first becomes a

                                       44
<PAGE>

director. In addition, beginning upon the closing of this offering, each non-
employee director who serves on a committee of the Board during the following
year will receive an option to purchase an additional 5,000 shares for each
committee seat the director holds. See "Employee Benefit Plans -- 2000 Equity
Incentive Plan".

Executive Compensation

(1) Mr. Shepard resigned as our Chief Operating Officer effective February 28,
    2000. In February 2000, Mr. Shepard exercised options to purchase 150,000
    shares of common stock, the vesting of options to purchase 37,500 shares of
    common stock was accelerated, and his remaining 412,500 unvested options
    were canceled.

   Each of the options set forth above was granted pursuant to our 1999 Equity
Incentive Plan and is subject to the terms of that plan. The options were
granted at an exercise price equal to the fair market value of our common stock
as determined by our Board of Directors on the date of grant. With the
exception of the options held by Mr. Shepard, the options are fully exercisable
and the shares purchasable upon exercise of such options are subject to
repurchase by Mercata at the original exercise price paid per share if the
optionee terminates his or her employment or attempts to transfer the shares
before the shares have vested. In this context, "vested" means that the shares
subject to, or issued upon exercise of, options are no longer subject to
repurchase by Mercata. The grant to Mr. Van Horn vests over thirty-nine months
at a rate of 9/48 of the shares subject to the option on October 3, 1998, and
1/48 of the shares subject to the option per month thereafter. The grant to
Mr. Engman and the first grant to Mr. Miller vest over thirty-six months at a
rate of 1/4 of the shares subject to the option on October 3, 1998, and 1/48 of
the shares subject to the option per month thereafter. The remaining grants
vest over forty-eight months at the rate of 1/4 of the shares subject to the
option on the first anniversary of the vesting commencement date specified in
the grant and 1/48 of the shares subject to the option per month thereafter.

   In 1999, we granted options to purchase up to a total of 4,547,600 shares to
employees, directors and consultants under our 1999 Equity Incentive Plan at
exercise prices equal to the fair market value of our common stock on the dates
of grant, as determined in good faith by our Board of Directors.

   The potential realizable value is calculated assuming that the aggregate
exercise price on the date of grant appreciates at the indicated rate for the
entire term of the option and that the option is exercised and sold on the last
day of its term at the appreciated price. All options listed have a term of 10
years. Stock price appreciation rates of 5% and 10% are assumed pursuant to the
rules of the Securities and Exchange Commission. We can give no assurance that
the actual stock price will appreciate over the 10-year option term at the
assumed 5% and 10% levels or at any other defined level. Actual gains, if any,
on stock option exercises will be dependent upon the future performance

                                       46
<PAGE>

of our common stock. Unless the market price of the common stock appreciates
over the option term, no value will be realized from the option grants made to
the above officers.

                Aggregated Option Exercises in Last Fiscal Year

   The following table sets forth the number of shares acquired the by the
officers listed in the Summary Compensation Table through the exercise of
options in 1999 and the value realized on those exercises. The value realized
is based on the fair market value of our common stock on the date of exercise,
as determined by the Board of Directors, less the exercise price payable for
the shares.

Employee Benefit Plans

1999 Equity Incentive Plan

   Our 1999 Plan was adopted by our Board of Directors in February 1999 and
subsequently approved by our stockholders. Our 1999 Plan provides for the grant
of incentive stock options to employees and nonstatutory stock options, stock
appreciation rights, stock bonuses and rights to acquire restricted stock to
our employees, directors and consultants. A total of 7,400,000 shares of common
stock have been reserved for issuance under the 1999 Plan.

   As of March 1, 2000, options to purchase 2,560,094 shares of common stock
were outstanding and 1,664,205 shares were available for future grant. Upon
completion of this offering, the 1999 plan will terminate, no further option
grants will be made under the 1999 Plan, and any shares reserved but not yet
issued under the 1999 Plan will not be carried over into the 2000 Plan.

   Our Board of Directors administers the 1999 Plan and may determine the terms
of options granted, including the exercise price, the number of shares subject
to individual option awards and the vesting period of the options. The Board of
Directors has delegated responsibility for approving option grants to new, non-
officer employees to the Option Committee. These grants must be within
guidelines prescribed by the Board of Directors. Grants to executive officers,
directors, or subsequent option grants to existing employees however, require
approval of the Board of Directors or the Compensation Committee. The exercise
price of incentive stock option grants to employees cannot

                                       47
<PAGE>

be lower than 100% of the fair market value of the common stock on the date of
grant. In the case of incentive stock options granted to employees who are
holders of more than 10% of our voting power, the exercise price cannot be less
than 110% of the fair market value. The term of an incentive stock option
cannot exceed ten years, and the term of an incentive stock option granted to a
holder of more than 10% of our voting power cannot exceed five years.
Nonstatutory options granted to employees, consultants or directors must have
an exercise price of at least 50% of the fair market value on the date of
grant. Options and stock purchase rights granted under our 1999 Plan generally
become exercisable at the rate of 25% of the total number of shares subject to
the option twelve months after the date of grant, and approximately 2.1% of the
shares subject to the option each month thereafter. The Board of Directors may
amend, suspend or terminate the 1999 Plan at any time as long as the amendment
or termination does not impair the rights of plan participants with respect to
outstanding options under the 1999 Plan.

   In February 2000, our Board of Directors authorized the amendment of certain
stock option agreements to allow optionholders to purchase shares issuable
under their option agreements before the shares have vested. All unvested
shares issued under this early exercise provision are subject to repurchase by
us at the original exercise price. All stock certificates representing
exercised but unvested shares are held in escrow until the shares have vested.

   In the event we are acquired in a merger or asset purchase, the successor
corporation will assume or substitute an equivalent option for each outstanding
option under the 1999 Plan. In the event that the successor corporation refuses
to assume or issue an equivalent option for each outstanding option, all
outstanding options, stock appreciation rights, stock bonuses and rights to
acquire restricted stock will become fully vested. After the date on which our
stock is first listed (or approved for listing) on notice of issuance on any
securities exchange or designated (or approved for designation) upon notice of
issuance as a national market security on an interdealer quotation system, if
Mercata undergoes a change in control and the successor corporation terminates
an optionholder's status as an employee or consultant, other than for cause,
within one month before or thirteen months following the change in control,
then the optionholder's options will become fully vested.

2000 Equity Incentive Plan

   Our 2000 Plan was adopted by our Board of Directors in March 2000. We intend
to submit the 2000 Plan to our stockholders for approval within 12 months of
the date of adoption. It will become effective upon the closing of this
offering. The 2000 Plan provides for the grant of incentive stock options to
employees and nonstatutory stock options, stock bonuses and stock purchase
rights to employees, directors and consultants. The 2000 Plan also provides for
nondiscretionary grants of nonstatutory options to non-employee directors.
Under this nondiscretionary grant mechanism, each non-employee director will
receive an option to purchase 40,000 shares of our common stock at the time he
or she first becomes a director. Our current directors will each receive this
initial grant upon the closing of this offering. The initial grant will vest
over four years in four equal annual installments. In addition, beginning upon
the closing of this offering, each non-employee director who will serve on a
committee of the Board during the following year will receive an option to
acquire an additional 5,000 shares for each committee seat the director holds.
Our current directors who serve on committees of the Board will each receive an
annual grant upon the closing of this offering. Each of these annual option
grants will vest in full one year from the date of grant. All options granted
to non-employee directors under this nondiscretionary grant mechanism will have
an exercise price equal to the fair market value of our common stock on the
date of grant.

   A total of 4,500,000 shares of common stock have been reserved for issuance
under the 2000 Plan. No shares or options have been issued under the 2000 Plan
prior to this offering. An

                                       48
<PAGE>

annual increase in the share reserve will be added on each January 1st
beginning in 2001, equal to the lesser of:

  .  1,500,000 shares;

  .  5% of the outstanding shares on that date; or

  .  a lesser amount determined by the Board of Directors.

   Our Board of Directors or a committee thereof will administer the 2000 Plan
and will determine the terms of options granted, including the exercise price,
the number of shares subject to individual option awards and the vesting period
of options. The exercise price of incentive stock option grants cannot be lower
than 100% of the fair market value on the date of grant and, in the case of
incentive stock options granted to employees who are holders of more than 10%
of our voting power, not less than 110% of the fair market value. The exercise
price of options granted to non-employee directors will be 100% of the fair
market value on the date of grant. The exercise price of nonstatutory stock
options may not be less than 85% of the fair market value on the date of grant.
The term of an incentive stock option or a nonstatutory stock option cannot
exceed ten years, and the term of an incentive stock option granted to a holder
of more than 10% of our voting power cannot exceed five years. The terms of
stock bonus awards and restricted stock awards are determined by the Board or
committee thereof. Stock bonus awards and restricted stock awards may, but need
not, be subject to a share repurchase option in favor of Mercata in accordance
with a vesting schedule determined by the Board. Options and other awards
granted under our 2000 Plan become exercisable as determined by the Board.

   If we are acquired in a merger or asset purchase, or if we dissolve or
liquidate or otherwise undergo a "change in control", the successor corporation
will assume or substitute an equivalent option for each outstanding option
under the 2000 Plan. If the successor corporation refuses to assume or issue an
equivalent option or other award for each outstanding option and award,
however, the options and awards will become fully vested and exercisable.
Following an assumption or substitution in connection with a merger or
acquisition, if the successor corporation terminates an optionholder's status
as an employee or consultant other than for cause within 12 months following
such merger or acquisition, then the optionholder's options will become fully
vested.

2000 Employee Stock Purchase Plan

   Our 2000 Purchase Plan was adopted by our Board of Directors in February
2000. We intend to submit the 2000 Purchase Plan to our stockholders for
approval within 12 months of the date of adoption. It will become effective
upon the closing of this offering. The 2000 Purchase Plan provides our
employees with an opportunity to purchase our common stock through accumulated
payroll deductions. A total of 250,000 shares of common stock has been reserved
for issuance under the 2000 Purchase Plan, none of which has been issued prior
to this offering. An annual increase in the share reserve under the 2000
Purchase Plan will be added on each January 1st, beginning in 2001, equal to
the lesser of:

  .  125,000 shares;

  .  1% of the outstanding shares on that date; or

  .  a lesser amount determined by the Board of Directors.

   The 2000 Purchase Plan will be administered by our Board of Directors or by
a committee appointed by the Board of Directors. The 2000 Purchase Plan will
permit eligible employees to purchase common stock through payroll deductions
of up to 15% of an employee's base compensation on each pay day during the
offering period. However, no employee may purchase more than $25,000 worth of
stock, determined at the fair market value of the shares at the time the

                                       49
<PAGE>

right is granted, in one calendar year. Employees employed by us on a given
enrollment date are eligible to participate during that offering period,
provided they remain employed by us for the duration of that offering period.

   Unless the Board of Directors or its committee determines otherwise, the
2000 Purchase Plan will be implemented in a series of overlapping offering
periods, each approximately 24 months in duration. However, the first offering
period will be approximately 27 months in duration, beginning on the effective
date of this offering. Offering periods contain four consecutive, six-month
purchase periods, and will begin on the first trading day on or after February
1 and August 1 of each year and terminate on the last trading day in the period
twenty-four months later.

   The first purchase period will commence on the date upon which the
registration statement, of which this prospectus is a part, is declared
effective by the Securities and Exchange Commission and terminate on the last
trading day in the period ending July 31, 2000. If we are acquired, and the
acquiring corporation refuses to assume all existing rights, offering and
purchase periods then in progress will be shortened and all rights
automatically exercised.

   The price at which common stock will be purchased under the 2000 Purchase
Plan is equal to 85% of the fair market value of our common stock on the first
day of the applicable offering period or the last day of the applicable
purchase period, whichever is lower. Employees may end their participation in
the offering period at any time, and participation automatically ends on
termination of employment.

   The Board of Directors may amend or terminate the 2000 Purchase Plan at any
time as long as the amendment or termination does not impair vesting rights of
plan participants. The 2000 Purchase Plan will terminate in January 2010,
unless terminated earlier in accordance with its provisions.

401(k) Plan

   Our employees currently are eligible to participate in the 401(k) plan of
Vulcan Northwest Inc. ("The PGA Companies 401(k) Plan"). Pursuant to The PGA
Companies 401(k) Plan, employees may elect to reduce their current compensation
and have the amount of such reduction contributed to the plan. After the
closing of this offering, we intend to establish a tax-qualified employee
savings and retirement plan for which our employees will generally be eligible
(the "401(k) Plan"). We intend for the 401(k) Plan to qualify under Section 401
of the Internal Revenue Code of 1986, as amended, so that contributions to the
401(k) Plan, and income earned on plan contributions, are not taxable to
employees until withdrawn from the 401(k) Plan, and so that our contributions,
if any, will be deductible when made by us. To date, we have made no matching
contributions. In the future, however, we may make discretionary matching
contributions to the 401(k) Plan. Additionally, we may make annual
discretionary profit sharing contributions in amounts to be determined annually
by the Board of Directors.

Limitation of Liability and Indemnification Matters

   Our Certificate of Incorporation limits the liability of directors to the
maximum extent permitted by Delaware law. Delaware law provides that directors
of a corporation will not be personally liable for monetary damages for breach
of their fiduciary duties as directors, except liability for:

  .  any breach of their duty of loyalty to the corporation or its
     stockholders;

  .  acts or omissions not in good faith or which involve intentional
     misconduct or a knowing violation of law;

  .  unlawful payments of dividends or unlawful stock repurchases or
     redemptions; or

  .  any transaction from which the director derived an improper personal
     benefit.

                                       50
<PAGE>

   Such limitation of liability does not apply to liabilities arising under the
federal securities laws and does not affect the availability of equitable
remedies such as injunctive relief or rescission.

   Our Certificate of Incorporation and Bylaws provide that we shall indemnify
our directors and executive officers and may indemnify our other officers and
employees and other agents to the fullest extent permitted by law. Our Bylaws
also permit us to secure insurance on behalf of any officer, director, employee
or other agent for any liability arising out of his or her actions in such
capacity, regardless of whether the Bylaws would permit indemnification.

   Upon the closing of this offering, we intend to enter into agreements to
indemnify our directors and certain officers, in addition to indemnification
provided for in our Certificate of Incorporation or Bylaws. These agreements,
among other things, will indemnify our directors and certain officers for
certain expenses, including attorneys' fees, judgments, fines and settlement
amounts incurred by any such person in any action or proceeding, including any
action by us, arising out of that person's services as our director or officer,
or that person's services provided to any other company or enterprise at our
request. We believe that these provisions and agreements are necessary to
attract and retain qualified persons as directors and officers. We also intend
to maintain liability insurance for our officers and directors.

   At present, we are not aware of any pending or threatened litigation or
proceeding involving a director, officer, employee or agent in which
indemnification would be required or permitted. We are not aware of any

                              Sales of Securities

   Since our inception in September 1998, we have issued and sold securities to
the persons identified below who are our directors, executive officers, or
holders of more than 5% of our common stock. You may find more details about
shares held by these purchasers in the "Principal Stockholders" section of this
prospectus. Similarly, stock option grants to our directors and executive
officers are described in this prospectus under the captions "Management --
 Board Compensation", "Management -- Executive Compensation" and "Principal
Stockholders".

Common Stock and Notes

   On October 7, 1998, we issued 4,000,000 shares of our common stock to Paul
G. Allen, the sole stockholder of Vulcan Ventures Incorporated, at a price of
$0.10 per share for an aggregate purchase price of $400,000. Mr. Allen
subsequently assigned the shares to Vulcan Ventures in March 1999. As a result
of the transactions discussed below, Vulcan Ventures currently holds 1,000,000
shares of common stock.

   From October 1998 to February 1999, we issued promissory notes to Mr. Allen
in the aggregate principal amount of $3,600,000. The notes each bore interest
at 6% per year and were payable upon demand at any time on or after December
31, 1999. Mr. Allen subsequently assigned the notes to Vulcan Ventures in March
1999 and, as a result of the conversions discussed below, the notes are no
longer outstanding.

Preferred Stock

   In March 1999, we sold an aggregate of 14,000,000 shares of Series A
preferred stock to Vulcan Ventures at a price per share of $1.05 for an
aggregate purchase price of $14,700,000. In exchange for the Series A preferred
stock, Vulcan Ventures assigned to us 3,000,000 shares of our outstanding
common stock with an aggregate value of $300,000, canceled the $3,600,000 in
promissory notes originally issued to Mr. Allen and then assigned to Vulcan
Ventures, and paid us $10,800,000 in cash.

   In September 1999 and October 1999, we sold an aggregate of 11,200,000
shares of Series B preferred stock at a price per share of $3.125 for an
aggregate purchase price of $35,000,000 to a group of private investors that
included the following directors and 5% stockholders:

In addition, Waelinvest, S.A., an existing stockholder, purchased a note that,
upon expiration of the waiting period under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, will be converted into 840,750 shares of Series C
preferred stock. Upon conversion of the note, Waelinvest will be a 5%
stockholder and will hold an aggregate of 1,261,125 shares of Series C
preferred stock.

   Pursuant to the sales of preferred stock described above, in September and
October 1999, we entered into an Investor Rights Agreement, a Co-Sale Agreement
and a Voting Agreement with the purchasers of our Series A and Series B
preferred stock, and we amended and restated these agreements in March 2000 to
include the purchasers of our Series C preferred stock. The purchasers listed
in the table above are parties to each of the agreements. Except for the
registration rights granted under the Amended and Restated Investor Rights
Agreement, all of the rights described below pursuant to the Amended and
Restated Investor Rights Agreement, the Amended and Restated Co-Sale Agreement
and the Amended and Restated Voting Agreement will terminate upon the closing
of this offering.

   Under the Amended and Restated Investor Rights Agreement, we agreed to
provide financial information to purchasers of our preferred stock on an
ongoing basis, as well as registration rights with respect to their shares of
common stock, including common stock issuable upon conversion of their
preferred stock. For a complete description of the registration rights, see
"Description of Capital Stock -- Registration Rights". Also, pursuant to the
Amended and Restated Investor Rights Agreement, holders of at least 300,000
shares (including shares held by their affiliates) have a right of first
refusal to purchase a pro rata share of any securities that we propose to issue
except, among other things, shares that we issue pursuant to this registration
statement.

   Pursuant to the Amended and Restated Co-Sale Agreement, all of the
purchasers of our preferred stock, other than Vulcan Ventures, have the right
to participate pro rata in sales of shares by Vulcan Ventures, except for sales
to affiliates of Vulcan Ventures, sales to the public and repurchases by
Mercata of shares held by Vulcan Ventures.

   Under the Amended and Restated Voting Agreement, the purchasers of our
preferred stock agreed to vote their shares to elect directors to our Board of
Directors as follows: one representative of Global Retail Partners Funding,
Inc., two representatives of Vulcan Ventures, one representative of Highland
Capital Partners IV Limited Partnership, one representative of the holders of a
majority of our common stock and our Chief Executive Officer. See
"Management --  Voting Agreement".

                       Transactions with Related Parties

   We have entered into a number of agreements and transactions with companies
affiliated with our directors and 5% stockholders. They include the following:

     Vulcan Northwest. We sublease approximately 17,332 square feet of office
  space from Vulcan Northwest at lease rates of approximately $37,000 per
  month, which we believe approximates fair market rates. In addition, for
  insurance purposes, we are named as an additional insured under an umbrella
  policy covering the Paul G. Allen group of companies.

     Vulcan Ventures. On September 10, 1999, we signed a promissory note in
  favor of Vulcan Ventures pursuant to which we were able to borrow up to
  $10.0 million at the prime interest rate as reported in the Wall Street
  Journal. All funds borrowed by us were payable on demand. We have repaid
  the outstanding balance in full. We canceled this note in March 2000.

     Go2Net. In May of 1999, we entered into a Web linking agreement with
  Go2Net involving a number of links and ad placements throughout Go2Net's
  network of Web sites. The agreement required payments to Go2Net over a 9-
  month period for a variety of specific placements and guaranteed minimum
  impressions for us on Go2Net's network. In February 2000, we entered into
  an addendum to the agreement, pursuant to which Go2Net joined the We-
  Commerce Network of Web sites. This addendum requires no additional
  payments by either party. In March 2000, we entered into a new advertising
  agreement with Go2Net, pursuant to which Go2Net will provide us services
  similar to those provided under the Web linking agreement, at similar
  monthly costs to us. William Savoy, Diane Daggatt and Linda Fayne Levinson
  are directors of Go2Net, and Vulcan Ventures is a significant shareholder
  of Go2Net.

     Seattle Seahawks. In July 1999, we entered into a contract with Football
  Northwest LLC, owner of the Seattle Seahawks franchise of the National
  Football League, pursuant to which we received numerous ad placements,
  including television commercials, "live" commentator announcements, stadium
  announcements and billboard placements, during the telecast of each
  preseason Seahawks game. In addition, the Seahawks produced, at their own
  cost, a television ad featuring one of the Seahawks players that was used
  as one of the ad spots shown during the preseason telecasts. Total
  consideration paid by us for these promotional benefits was $40,000. In
  August 1999, we agreed with Football Northwest to extend the Seahawk
  promotions into the regular season. This contract involved various print,
  in-stadium, and certain television network promotions within the Seahawk's
  weekly "Seahawks Saturday" show. Total consideration paid by us for these
  promotions was $67,000. In March 2000, we entered into a We-Commerce
  Network Services Agreement, pursuant to which Football Northwest LLC joined
  the We-Commerce Network. The agreement requires that we pay a 5% commission
  on revenues from sales made on the Seahawks.com Web site through the We-
  Commerce Network. Paul Allen owns Football Northwest Management Inc., which
  owns Football Northwest LLC.

     Portland Trailblazers. In October 1999, we entered into a sponsorship
  agreement with the Portland Trailblazers National Basketball Association
  franchise, pursuant to which we will receive numerous television
  commercials, in-game features, live PowerBuy announcements, print
  advertising, in-arena promotions and on-line banner advertising. The
  approximate consideration for the sponsorship agreement is $130,000. Paul
  Allen owns Trail Blazers, Inc., which owns the Portland Trailblazers. Bert
  Kolde is a director of Trail Blazers, Inc.

     CyberSource. In March 1999, we entered into a contract with CyberSource
  Corporation for fraud checking and other services, which we expect will
  involve payments to CyberSource of over $60,000 per year. Bert Kolde and
  Linda Fayne Levinson both are directors of CyberSource.

                                       54
<PAGE>

     BeFree, Inc. On August 5, 1999, we entered into a contract with BeFree,
  Inc., pursuant to which BeFree will support our affiliate program. The
  agreement requires us to pay BeFree a percentage of monthly net sales
  generated through our affiliate programs that are supported by BeFree. We
  expect these fees to exceed $60,000 per year. Highland Capital Partners is
  a significant shareholder of BeFree, and Dan Nova is a director of BeFree.

   We believe that all transactions with affiliates described above were made
on terms no less favorable to us than could have been obtained from
unaffiliated third parties. We expect that a majority of the independent and
disinterested outside directors on our Board of Directors will approve all
future transactions between us and our officers, directors, principal
stockholders and their affiliates. We expect that such transactions will
continue to be on terms no less favorable to us than we could obtain from
unaffiliated third parties.

   We plan to enter into indemnification agreements with our executive officers
and directors for the indemnification of and advancement of expenses to such
persons to the fullest extent permitted by law. We also intend to enter into
these agreements with our future directors and executive officers. For a
description of limitations of liability and certain indemnification
arrangements with respect to our directors and officers, see "Management --
 Limitation of Liability and Indemnification Matters".

all outstanding shares of preferred stock upon the closing of this offering and
treating as outstanding all options exercisable within 60 days of March 1,
2000, held by the optionee. Shares subject to options, however, are not deemed
outstanding for the purpose of computing the percentage ownership of any other
stockholder. Percentage of beneficial ownership after the offering is also
based on shares of common stock outstanding after the completion of the
offering, assuming no exercise of the underwriters' over-allotment option.

                          DESCRIPTION OF CAPITAL STOCK

   Upon the completion of this offering, our authorized capital stock will
consist of     shares of common stock, $0.001 par value, and 5,000,000 shares
of preferred stock, $0.001 par value. The following description of our capital
stock does not purport to be complete. This description is subject to and
qualified in its entirety by our Certificate of Incorporation and Bylaws, which
are included as exhibits to the registration statement of which this prospectus
forms a part, and by the provisions of Delaware law.

Common Stock

   As of March 1, 2000, there were 4,205,701 shares of common stock outstanding
that were held of record by 61 stockholders. There will be       shares of
common stock outstanding after giving effect to the sale of common stock in
this offering.

   The holders of common stock are entitled to one vote per share on all
matters to be voted upon by the stockholders. Subject to preferences that may
be applicable to any outstanding preferred stock, the holders of common stock
are entitled to receive ratably those dividends, if any, that may be declared
from time to time by our Board of Directors out of funds legally available for
dividends. See "Dividend Policy". In the event of the liquidation, dissolution
or winding up of Mercata, the holders of our common stock are entitled to share
ratably in all assets remaining after payment of liabilities, subject to prior
distribution rights of preferred stock, if any, then outstanding. The common
stock does not have cumulative voting rights. The common stock has no
preemptive or conversion rights or other subscription rights. No redemption or
sinking fund provisions apply to the common stock. All outstanding shares of
common stock are fully paid and nonassessable, and the shares of common stock
to be issued upon completion of this offering will be fully paid and
nonassessable.

Preferred Stock

   Subject to stockholder approval, at the closing of this offering our Board
of Directors will have the authority to issue preferred stock in one or more
series and to fix or alter from time to time the designation, powers,
preferences and rights of the shares of each such series, and the
qualifications, limitations or restrictions of any wholly unissued series of
preferred stock, and to establish from time to time the number of shares
constituting any such series. The issuance of preferred stock may have the
effect of delaying, deferring or preventing a change in control of Mercata
without further action by the stockholders. For example, our Board of Directors
could issue preferred stock that has the power to prevent a change of control
transaction. The issuance of preferred stock with voting and conversion rights
may adversely affect the voting power of the holders of common stock, including
the loss of voting control to others. Upon the closing of this offering, no
shares of preferred stock will be outstanding, and we currently have no plans
to issue any of the preferred stock.

Registration Rights

   At the closing of this offering, the holders of 28,722,250 shares of common
stock will be entitled to rights with respect to the registration of such
shares ("Registrable Securities") under the Securities Act. Registrable
Securities include shares of our common stock issued upon conversion of our
Series A, Series B and Series C preferred stock, as well as 1,000,000 shares of
our common stock held by Vulcan Ventures Incorporated. Beginning 180 days after
this offering, holders of such securities may require us to use our best
efforts to file a registration statement under the Securities Act, provided
that the proposed aggregate offering price exceeds $25,000,000. If we propose
to register any of our securities under the Securities Act, either for our own
account or for the account

                                       58
<PAGE>

of other security holders exercising registration rights, such holders are
entitled to notice of such registration and are entitled to include shares of
common stock in such registration, subject to the ability of the underwriters
to limit the number of shares included in the offering. Furthermore, holders of
Registrable Securities may require us to register all or a portion of their
common stock subject to these rights on Form S-3, when use of this form becomes
available, provided that, among other limitations, the proposed aggregate
offering price would be at least $2,000,000. All fees and expenses of such
registrations (other than underwriting discounts and commissions) will be borne
by us. The registration rights of a holder terminate when the holder can,
within a three-month period, offer and sell all of his or her registrable
securities pursuant to Rule 144 and, as to all holders, three years after this
offering.

Antitakeover Effects of Charter Documents, Delaware Law and Washington Law

   Provisions of our Certificate of Incorporation and Bylaws may be deemed to
have an antitakeover effect and may delay, defer or prevent a tender offer or
takeover attempt that a stockholder might consider in his best interest,
including those attempts that might result in a premium over the market price
for the shares held by our stockholders.

   Advance Notice Requirements for Stockholder Proposals and Director
Nominations. The Bylaws provide that stockholders seeking to bring business
before an annual meeting of stockholders, or to nominate candidates for
election as directors at an annual meeting of stockholders, must provide timely
notice thereof in writing. To be timely, a stockholder's notice must be
delivered to or mailed and received at our principal executive offices not less
than 60 days or more than 90 days prior to the first anniversary of our
previous year's annual meeting. The Bylaws also specify requirements as to the
form and content of a stockholder's notice. These provisions may preclude
stockholders from bringing matters before an annual meeting of stockholders or
from making nominations for directors at an annual meeting of stockholders.

   Authorized But Unissued Shares. The authorized but unissued shares of common
stock and preferred stock will be available for future issuance without
stockholder approval following the closing of this offering. These additional
shares may be utilized for a variety of corporate purposes, including future
public offerings to raise additional capital, corporate acquisitions and
employee benefit plans. The existence of authorized but unissued shares of
common stock and preferred stock could render more difficult or discourage an
attempt to obtain control of us by means of a proxy contest, tender offer,
merger or otherwise.

   Classified Board of Directors; Removal. Subject to stockholder approval,
following this offering, our Board of Directors will be divided into three
classes. The classification of the Board of Directors will have the effect of
requiring at least two annual stockholder meetings, instead of one, to replace
a majority of the directors which could have the effect of delaying or
preventing a change in control of Mercata. Subject to the rights of the holders
of any outstanding series of preferred stock, the Certificate of Incorporation
authorizes only the Board of Directors to fill vacancies, including newly
created directorships. Subject to stockholder approval, the Certificate of
Incorporation also will provide that directors may be removed by stockholders
only for cause and only by the affirmative vote of holders of a majority of the
outstanding shares of voting stock.

   Right of First Refusal. Our Bylaws provide Mercata with a right of first
refusal with respect to certain transfers of stock by existing stockholders.
This right of first refusal will expire upon the closing of this offering.

   Business Combination Statutes. In addition, we are subject to the provisions
of Section 203 of the Delaware General Corporation Law. Subject to exceptions,
Section 203 prohibits a publicly-held Delaware corporation from engaging in a
"business combination" with an "interested

                                       59
<PAGE>

stockholder" for a period of three years from the date of the transaction in
which the person became an interested stockholder, unless the interested
stockholder attained this status with the approval of the Board of Directors or
unless the business combination is approved in a prescribed manner. A "business
combination" includes mergers, asset sales and other transactions resulting in
a financial benefit to the interested stockholder. Subject to exceptions, an
"interested stockholder" is a person who, together with affiliates and
associates, owns, or within three years did own, 15% or more of the
corporation's voting stock. This statute could prohibit or delay the
accomplishment of mergers or other takeover or change in control in attempts
with respect to Mercata and, accordingly, may discourage attempts to acquire
Mercata. Although a corporation may opt out of this statute, we have not.

   Finally, the laws of Washington, where our principal executive offices are
located, impose restrictions on transactions between foreign corporations and
significant stockholders. Chapter 23B.19 of the Washington Business Corporation
Act generally prohibits a target corporation from engaging in significant
business transactions with an acquiring person. An acquiring person is defined
as a person or group of persons that beneficially owns 10% or more of the
voting securities of the target corporation, for a period of five years after
the acquisition, unless a majority of the members of the target corporations's
board of directors approves the transaction before the acquisition. Prohibited
transactions include

  .  a merger or consolidation with, disposition of assets to, or issuance or
     redemption of stock to or from, the acquiring person;

  .  termination of 5% or more of the employees of the target corporation as
     a result of the acquiring person's acquisition of 10% or more of the
     shares; and

  .  allowing the acquiring person to receive any disproportionate benefit as
     a stockholder.

   After the five-year period, a significant business transaction may take
place so long as it complies with the fair price provisions of the statute or
is approved at an annual or special meeting of stockholders. A target
corporation includes a foreign corporation if

  .  the corporation's principal executive office is located in Washington;

  .  any of (a) more than 10% of the corporation's stockholders of record are
     Washington residents, (b) more than 10% of its shares of record are
     owned by Washington residents or (c) 1,000 or more of its stockholders
     of record are Washington residents;

  .  a majority of the corporation's employees are Washington residents or
     more than 1,000 Washington residents are employees of the corporation;
     and

  .  a majority of the corporation's tangible assets are located in
     Washington or the corporation has more than $50 million of tangible
     assets located in Washington.

   A corporation may not opt out of this statute. If we continue to meet the
definition of a target corporation, Chapter 23B.19 of the Washington Business
Corporation Act may have the effect of delaying, deferring or preventing a
change of control of Mercata.

                        SHARES ELIGIBLE FOR FUTURE SALE

   Prior to the offering, there was no public market for our common stock.
Based on shares outstanding at March 1, 2000, upon completion of the offering
we will have       shares of common stock outstanding, assuming no exercise of
the underwriters' over-allotment option and no exercise of outstanding options.
Of these outstanding shares, the       shares sold in the offering will be
freely tradeable without restrictions or further registration under the
Securities Act, unless such shares are purchased by our affiliates as that term
is defined in Rule 144 under the Securities Act.

Sales of Restricted Shares

   The remaining 31,927,951 shares of common stock outstanding after the
offering are restricted securities under Rule 144 or Rule 701. Restricted
shares may be sold in the public market only if registered or if they qualify
for an exemption from registration under Rule 144, 144(k) or 701 promulgated
under the Securities Act, which are summarized below. No restricted shares will
be available for resale in the public market in reliance on Rule 144(k) on the
date of this prospectus. Upon expiration of the lock-up agreements described
below, 180 days after the date of this prospectus, an additional 28,075,701
shares will be available for resale in the public market in reliance on Rule
144.

   Rule 144. In general, under Rule 144 as currently in effect, beginning 90
days after the date of this prospectus, a person who has beneficially owned
restricted shares for at least one year is entitled to sell a number of shares
within any three-month period that cannot exceed the greater of one percent of
the number of shares of common stock then outstanding, which will equal
approximately      shares immediately after the offering, and the average
weekly trading volume of our common stock on the Nasdaq National Market during
the four calendar weeks preceding the filing of a notice on Form 144 with
respect to such sale. Sales under Rule 144 are also subject to manner of sale
provisions, notice requirements and the availability of current public
information about Mercata. Rule 144 also provides that affiliates who are
selling shares of common stock that are not restricted shares must nonetheless
comply with the same restrictions applicable to restricted shares, with the
exception of the holding period requirement.

   Rule 144(k). Under Rule 144(k), a person who is not deemed to have been our
affiliate at any time during the 90 days preceding a sale, and who has
beneficially owned the shares proposed to be sold for at least two years, is
entitled to sell such shares without complying with the manner of sale, public
information, volume limitation or notice provisions of Rule 144. Accordingly,
unless otherwise restricted, these shares may therefore be sold immediately
upon the completion of the offering. Because Mercata was formed less than two
years ago, no shares will be available for resale in the public market in
reliance on Rule 144(k) on the date of this prospectus.

Options

   Rule 701 provides that the shares of common stock acquired upon the exercise
of currently outstanding options or pursuant to other rights granted under our
stock plans may be resold (to the extent not subject to the lock-up agreements)
by persons, other than affiliates, beginning 90 days after the date of this
prospectus, subject only to the manner of sale provisions of Rule 144, and by
affiliates under Rule 144, without compliance with its one-year minimum holding
period, subject to certain limitations. As of the date of this prospectus, the
Board of Directors has authorized an aggregate of up to 7,400,000 shares of
common stock for issuance pursuant to our 1999 Plan. As of March 1, 2000,
options to purchase a total of 2,560,094 shares of common stock were
outstanding, 1,091,918 of which options are exercisable. Of the total shares
issuable pursuant to such options, all are subject to contractual lock-up
agreements with the Company. At the completion of this offering an

                                       61
<PAGE>

aggregate of 4,750,000 shares of common stock will be reserved for issuance
under our 2000 Plan and our 2000 Purchase Plan, and no further options or other
stock awards may be granted under our 1999 Plan.

   We intend to file one or more registration statements on Form S-8 under the
Securities Act following the offering to register the shares of common stock
which are issuable pursuant to our stock option and stock purchase plans. These
registration statements are expected to become effective upon filing. Shares
covered by these registration statements will then be eligible for sale in the
public markets, subject to any applicable lock-up agreements and to Rule 144
limitations applicable to affiliates.

Lock-up Agreements

   Except for sales of common stock to the underwriters pursuant to the
underwriting agreement and in limited other transactions, Mercata, our
executive officers and directors and some of our stockholders and optionholders
have agreed not to, among other things, sell or otherwise dispose of, directly
or indirectly, any shares of common stock (or any security convertible into or
exchangeable or exercisable for common stock) without the prior written consent
of Goldman, Sachs & Co. for a period of 180 days from the date of this
prospectus. Goldman, Sachs & Co. may, in its sole discretion, at any time and
without notice, release for sale in the public market all or any portion of the
shares subject to the lock-up agreements.

Registration Rights

   Registration rights held by certain of our stockholders are described in
this prospectus under the caption "Description of Capital Stock -- Registration
Rights".

Effects of Sales of Shares

   Prior to the offering, there has been no public market for our common stock.
No predictions can be made as to the effect, if any, that market sales of
shares of our common stock from time to time, or the availability of shares for
future sale, may have on the market price for our common stock. Sales of
substantial amounts of common stock, or the perception that such sales could
occur, could adversely effect prevailing market prices for our common stock and
could impair our future ability to obtain capital through an offering of equity
securities.

   If the underwriters sell more shares than the total number set forth in the
table above, the underwriters have an option to buy up to an additional
shares from Mercata to cover such sales. They may exercise that option for 30
days. If any shares are purchased pursuant to this option, the underwriters
will severally purchase shares in approximately the same proportion as set
forth in the table above.

   The following table shows the per share and total underwriting discounts and
commissions to be paid to the underwriters by Mercata. Such amounts are shown
assuming both no exercise and full exercise of the underwriters' option to

   Shares sold by the underwriters to the public will initially be offered at
the initial public offering price set forth on the cover of this prospectus.
Any shares sold by the underwriters to securities dealers may be sold at a
discount of up to $       per share from the initial public offering price. Any
such securities dealers may resell any shares purchased from the underwriters
to certain other brokers or dealers at a discount of up to $       per share
from the initial public offering price. If all the shares are not sold at the
initial public offering price, the representatives may change the offering
price and the other selling terms.

   Mercata, its directors, officers and certain of its stockholders have agreed
with the underwriters not to dispose of or hedge any of their common stock or
securities convertible into or exchangeable for common stock during the period
from the date of this prospectus continuing through the date 180 days after the
date of this prospectus, except with the prior written consent of the
representatives. Please see "Shares Eligible for Future Sale" for a discussion
of certain transfer restrictions.

   At Mercata's request, the underwriters have reserved, at the initial public
offering price, up to       shares of common stock for sale to certain
directors, officers, employees and friends of

                                       63
<PAGE>

Mercata. There can be no assurance that any of the reserved shares will be so
purchased. The number of shares available for sale to the general public in the
offering will be reduced by the number of reserved shares sold. Any reserved
shares not purchased will be offered to the general public on the same basis as
the other shares offered in this prospectus.

   Prior to this offering, there has been no public market for the shares. The
initial public offering price will be negotiated among Mercata and the
representatives. Among the factors to be considered in determining the initial
public offering price of the shares, in addition to prevailing market
conditions, will be Mercata's historical performance, estimates of its business
potential and earnings prospects, an assessment of its management and the
consideration of the above factors in relation to market valuation of companies
in related businesses.

   Mercata has applied to list the common stock on the Nasdaq National Market
under the symbol "MCTA".

   In connection with the offering, the underwriters may purchase and sell
shares of common stock in the open market. These transactions may include short
sales, stabilizing transactions and purchases to cover positions created by
short sales. Short sales involve the sale by the underwriters of a greater
number of shares than they are required to purchase in the offering.
Stabilizing transactions consist of certain bids or purchases made for the
purpose of preventing or retarding a decline in the market price of the common
stock while the offering is in progress.

   The underwriters also may impose a penalty bid. This occurs when a
particular underwriter repays to the underwriters a portion of the underwriting
discount received by it because the representatives have repurchased shares
sold by or for the account of such underwriter in stabilizing or short covering
transactions.

   These activities by the underwriters may stabilize, maintain or otherwise
affect the market price of the common stock. As a result, the price of the
common stock may be higher than the price that otherwise might exist in the
open market. If these activities are commenced, they may be discontinued by the
underwriters at any time. These transactions may be effected on the Nasdaq
National Market, in the over-the-counter market or otherwise.

   The underwriters do not expect sales to discretionary accounts to exceed
five percent of the total number of shares offered.

   Mercata estimates that its share of the total expenses of the offering,
excluding underwriting discounts and commissions, will be approximately $     .

   Mercata has agreed to indemnify the several underwriters against certain
liabilities, including liabilities under the Securities Act.

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors and Shareholders
Mercata, Inc.:

   We have audited the accompanying balance sheets of Mercata, Inc. as of
December 31, 1998 and 1999, and the related statements of operations,
stockholders' equity (deficit), and cash flows for the period from September
23, 1998 (inception) to December 31, 1998 and the year ended December 31, 1999.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.

   We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

   In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Mercata, Inc. as of
December 31, 1998 and 1999, and the results of its operations and its cash
flows for the period from September 23, 1998 (inception) to December 31, 1998
and the year ended December 31, 1999 in conformity with generally accepted
accounting principles.

                         NOTES TO FINANCIAL STATEMENTS

(1) Business and Summary of Significant Accounting Policies

  (a) Description of Business

   Mercata, Inc. (Company) is a provider of Internet-based demand aggregation
services that empower buyers with common purchasing interests to achieve
discounts on high-quality, brand-name products and services. On the Company's
Mercata.com Web site, buyers can participate in group buying through PowerBuy
group purchases and can also purchase products at fixed prices. For online
businesses, the Company also offers an e-commerce solution, known as the We-
Commerce Network, that enables merchants and portal, community and content Web
sites to offer merchandise for sale using its proprietary business methods and
technology.

   The Company was incorporated on September 23, 1998 and launched its Web site
and commenced commercial operations in May 1999. The Company was previously
considered a development stage company. The Company has incurred significant
operating losses since its inception and has limited working capital. The
Company has financed its operations to date primarily through the issuance of
equity securities. Further development and establishment of the Company's
business will require additional equity financing. The Company believes that
equity financing can be obtained from existing or new investors. However, there
can be no assurance that the Company will be able to obtain such equity
financing on acceptable terms, if at all.

  (b) Use of Estimates

   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, liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and reported amounts of net sales and expenses during the reporting
period. Actual results could differ from those estimates.

  (c) Cash and Cash Equivalents

   Cash equivalents are carried at cost plus accrued interest, which
approximates fair value. For purposes of the statements of cash flows, the
Company considers all highly liquid investments with maturities at the date of
purchase of three months or less to be cash equivalents.

  (d) Accounts Receivable

   The Company generally does not extend credit to customers, except through
third-party issued credit cards. The Company's agreements with third-party
credit card companies provide for the electronic processing of credit approvals
and the electronic submission of transactions. The Company does not bill
customers' credit cards until the products ordered by the customers have been
shipped. The Company records these amounts as accounts receivable upon the
electronic submission of the transaction to the appropriate processing agency,
and as collections upon remittance of the funds to the Company's bank account.

  (e) Inventories

   Inventories are stated at the lower of cost or market. Cost is determined
using the first-in, first-out method.

  (f) Property and Equipment

   Property and equipment are stated at cost, less accumulated depreciation and
amortization. Depreciation on property and equipment is calculated on the
straight-line method over the estimated useful lives of the assets, which range
from three to five years. Leasehold improvements are amortized straight line
over the shorter of the lease term or estimated useful life of the asset.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)


   In accordance with the provisions of the American Institute of Certified
Public Accountants Statement of Position 98-1 (SOP 98-1), the Company
capitalizes certain costs related to development of internal-use software for
its enterprise reporting and transaction processing systems. Total capitalized
costs to acquire or develop internal-use software was $650,745 and $2,630,238
for the period ended December 31, 1998 and the year ended December 31, 1999,
respectively. Capitalized costs consisted primarily of external direct costs
for software licenses and services, and payroll and payroll-related costs for
employees who were directly involved in such development projects.

  (g) Impairment of Long-lived Assets

   The Company accounts for long-lived assets in accordance with the provisions
of Statement of Financial Accounting Standards (SFAS) No. 121, "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of." This Statement requires that long-lived assets and certain identifiable
intangibles be reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable. Recoverability of assets to be held and used is measured by a
comparison of the carrying amount of an asset to undiscounted future net cash
flows expected to be generated by the asset. If such assets are considered to
be impaired, the impairment to be recognized is measured by the amount by which
the carrying amount of the assets exceeds the fair value of the assets. To
date, no such impairment has been indicated.

  (h) Revenue Recognition

   The Company recognizes revenues from product sales at the time the title to
the product passes from the Company to the customer. Revenues are recorded net
of promotional discounts and allowance for sales returns. The Company provides
an estimated allowance for sales returns in the period of sale that is based on
industry and historical experience. For all product sales transactions with its
customers, the Company takes title to all products sold, bears credit risk and
bears inventory risk for returned products that are not successfully returned
to suppliers, although these risks are mitigated through arrangements with
credit card issuers, shippers and suppliers.

  (i) Cost of Revenues

   Cost of revenues consists primarily of the cost of merchandise sold to
customers, inbound freight, handling charges at our third-party warehouse and
expedited shipping costs, net of expedited shipping revenues. Cost of revenues
excludes costs of merchandise associated with promotional credits used for new
customer purchases, such as Mercata$ store credits. These costs are included in
sales and marketing expenses.

  (j) Sales and Marketing Expenses

   Sales and marketing expenses consist primarily of advertising, public
relations and third-party fulfillment fees, as well as payroll and related
expenses for personnel engaged in marketing, sales and related activities.
These expenses also include promotional expenditures, such as free ground
shipping and the cost of merchandise associated with promotional credits used
for new customer purchases.

   Advertising costs are expensed as incurred and totaled $0 and approximately
$21,460,000 for the periods ended December 31, 1998 and 1999, respectively.
Prepaid marketing expenses

represent media advertisements purchased by the Company but not yet delivered
by advertisers at the balance sheet date. The costs of merchandise associated
with promotional discount programs used for new customer purchases are included
in sales and marketing expense and totaled approximately $2.4 million for the
year ended December 31, 1999.

  (k) Technology and Development Expenses

   Technology and development expenses consist primarily of payroll and related
expenses for development, Web site design and network operations, as well as
systems infrastructure costs.

  (l) Stock-based Compensation

   The Company accounts for its stock option plans for employees in accordance
with the provisions of Accounting Principles Board (APB) Opinion No. 25,
"Accounting for Stock Issued to Employees," and related interpretations. As
such, compensation expense related to fixed employee stock options is recorded
only if, on the date of grant, the fair value of the underlying stock exceeded
the exercise price. The Company has adopted the disclosure-only requirements of
SFAS No. 123, "Accounting for Stock-Based Compensation," which allows entities
to continue to apply the provisions of APB No. 25 for transactions with
employees and provide pro-forma net income (loss) and pro forma earnings per
share disclosures as if the fair value based method of accounting in
SFAS No. 123 had been applied to employee stock option grants.

  (m) Income Taxes

   The Company computes income taxes under the asset and liability method.
Under this method, deferred tax assets and liabilities are determined based on
differences between the financial statement carrying amounts of existing assets
and liabilities and their respective tax bases and operating loss and tax
credit carryforwards and are measured using the enacted tax rates expected to
apply to taxable income in the years in which those temporary differences are
expected to be recovered or settled. The effect on deferred tax assets and
liabilities of a change in tax rate is recognized in income in the period that
includes the enactment date.

  (n) Fair Value of Financial Instruments

   The Company's financial instruments include cash and cash equivalents,
accounts receivable, notes payable, accounts payable and accrued expenses. The
carrying value of these financial instruments approximates their fair values.

  (o) Net Loss per Share

   Basic net loss per share is computed on the basis of the weighted-average
number of common shares outstanding for all periods presented. Diluted net loss
per share is computed on the basis of the weighted-average number of common
shares plus the dilutive potential common shares outstanding. Securities that
could potentially dilute basic income per share consist of outstanding stock
options and convertible preferred stock. As the Company has incurred net losses
in each of the periods presented, basic and diluted net loss per share are the
same. There were no dilutive potential securities outstanding in 1998. Dilutive
potential securities outstanding in 1999 that were not included in the
computation of diluted earnings per share included preferred stock convertible
into 25.2 million common shares and options to purchase approximately 3.7
million common shares at a weighted average exercise price of $0.18 per share.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)


  (p) Comprehensive Income

   The Company has adopted SFAS No. 130, "Reporting Comprehensive Income,"
which establishes standards for the reporting and presentation of comprehensive
income and its components in a full set of financial statements. Comprehensive
income is defined as the change in net assets of a business enterprise during a
period from transactions generated from nonowner sources. It includes all
changes in equity during a period except those resulting from investments by
owners and distributions to owners. There were no significant differences
between the Company's net loss and comprehensive loss in the periods presented.

  (q) Segment and Geographic Information

   The Company identifies its operating segments based on business activities
and management responsibility. The Company operates in a single business
segment across domestic markets selling consumer products online. Substantially
all of the Company's assets and operations are in the United States.

  (r) Concentrations of Risk

   The Company purchases a majority of its products from seven distributors.
The Company does not have long-term contracts or arrangements with these
distributors and alternative sources of supply exist should changes be
necessary. However, loss of any of these distributors could have an adverse
affect on the Company's operations until alternative sources of supply are
secured. Revenue on merchandise fulfilled by these distributors approximated
67% of net revenues for the year ended December 31, 1999.

   The Company uses a third-party fulfillment organization for the warehousing
of its inventory and the shipping, packaging and handling of products purchased
by customers. The Company's reliance on an external source of warehousing and
order fulfillment can be shifted should such a change be necessary. However, if
the fulfillment house becomes unable to provide services, the Company's
operations could be disrupted until an alternative source is secured. Revenue
on merchandise fulfilled by this fulfillment organization approximated 33% of
net revenues for the year ended December 31, 1999.

  (s) New Accounting Pronouncements

   The Financial Accounting Standards Board issued SFAS No. 133, "Accounting
for Derivative Instruments and Hedging Activities" in June 1998. SFAS No. 133
establishes accounting and reporting standards for derivative instruments,
including certain derivative instruments embedded in other contracts, and for
hedging activities. It requires that an entity recognize all derivatives as
either assets or liabilities in the balance sheet and measure those instruments
at fair value. If certain conditions are met, a derivative may be specifically
designated as a hedge. The accounting for changes in the fair value of a
derivative depends on the intended use of the derivative and the resulting
designation. SFAS No. 133, as amended by SFAS No. 137, is effective for all
fiscal quarters of fiscal years beginning after June 15, 2000. The adoption of
this statement is not expected to have a material impact on the Company's
financial statements.

   In December 1999, the United States Securities and Exchange Commission (SEC)
released Staff Accounting Bulletin (SAB) No. 101 "Revenue Recognition in
Financial Statements," which must be applied in the Company's first fiscal
quarter of 2000. SAB No. 101 provides guidance on revenue recognition and the
SEC staff's views on the application of accounting principles to selected
revenue

                                 MERCATA, INC.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

recognition issues. The Company does not expect that the adoption of SAB No.
101 will have a material effect on its financial statements.

   In October 1999, the SEC identified a list of issues that have arisen in
Internet businesses which the SEC believes should be addressed by the Emerging
Issues Task Force (EITF) of the Financial Accounting Standards Board or other
standard setting bodies. While the EITF is in the process of addressing such
issues, many of the identified issues have not yet been resolved. Future
resolution of all of the issues identified by the SEC may affect the Company's
financial statements. The Company is not able to determine the impact of on its
financial statements, if any, of such future rule making.

  (t) Initial Public Offering and Unaudited Pro Forma Information

   In February 2000, the board of directors authorized the filing of a
registration statement with the SEC that would permit the Company to sell
shares of the Company's common stock in connection with a proposed initial
public offering (IPO). If the offering is consummated under the terms presently
anticipated, all of the then outstanding shares of the Company's convertible
preferred stock will automatically convert into shares of common stock on a
one-for-one basis upon closing of the proposed IPO. The pro forma information
on the accompanying balance sheet as of December 31, 1999 reflects the issuance
of Series C preferred stock and a convertible note payable (see note 6), and
the conversion of all convertible preferred stock outstanding as of March 1,
2000 as if these transactions had occurred on December 31, 1999.

   Pro forma basic and diluted loss per share and pro forma weighted average
common shares used in the calculation of pro forma basic and diluted loss per
share for the year ended 1999 are $(2.25) and 16,044,345, respectively,
assuming conversion at issuance of the convertible preferred stock issued in
1999.

</TABLE>

   For the periods ended December 31, 1998 and 1999, depreciation and
amortization expense was $12,438 and $822,220, respectively.

(4) Employee Benefit Plans

   The Company has a savings plan (the 401(k) Plan), which qualifies as a
defined contribution arrangement under Section 401(a), 401(k) and 501(a) of the
Internal Revenue Code. Under the 401(k) Plan, participating employees may defer
a percentage (not to exceed 15%) of their eligible pretax earnings up to the
Internal Revenue Code's annual contribution limit. All employees on the payroll
of the Company are eligible to participate in the 401(k) Plan. The Company will
determine its contributions, if any, based on its current profits or retained
earnings; however, no contributions have been made since the inception of the
401(k) Plan.

(5) Notes Payable to Stockholders

   In 1998, the Company issued notes payable to a stockholder totaling
$2,400,000. In 1999, the Company issued additional notes payable to a
stockholder totaling $1,200,000. The notes were payable on demand anytime on or
before December 31, 1999 with annual interest accruing at 6%. These notes,
totaling $3,600,000 were exchanged for 3,428,571 shares of Series A preferred
stock in March 1999. In September 1999, the Company issued notes payable to a
stockholder totaling $2,395,835. These notes were convertible into Series B
preferred stock and were converted into 766,667 shares of Series B preferred
stock in October 1999.

   In September 1999, the Company issued a promissory note payable to a
stockholder that enabled the Company to borrow up to $10,000,000. Disbursements
under the note payable bear interest at the quoted prime rate (8.5% at December
31, 1999) and are payable on demand. In September 1999, the Company borrowed
$2,000,000 under this note payable. The principal, plus accrued interest of
$9,945 was repaid in October 1999. As of December 31, 1999, the Company may
borrow up to an additional $8,000,000 under this note. The Company canceled
this note in March 2000.

(6) Stockholders' Equity

  (a) Incorporation and Authorized Capital

   In September 1998, the Company was incorporated in the state of Delaware
with authorized capital of 10,000,000 shares of $.001 par value common stock.
In March 1999, the Company

                                      F-12

                                 MERCATA, INC.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

increased its authorized capital to 21,000,000 shares of common stock and
14,000,000 shares of $.001 par value preferred stock. In September 1999, the
Company increased its authorized common stock to 40,000,000 shares and
increased its authorized preferred stock to 30,000,000 shares.

  (b) Convertible Preferred Stock

   In March 1999, the Company entered into a Stock Purchase Agreement with a
common stockholder under which the Company agreed to issue and sell 14,000,000
shares of Series A preferred stock for a purchase price of $1.05 per share in
exchange for cash of $10,800,000, promissory notes of $3,600,000, and 3,000,000
shares of outstanding common stock.

   In September and October 1999, the Company issued 10,433,333 shares of
Series B preferred stock in a private placement offering in exchange for gross
cash proceeds of $32,604,165. In September 1999, two promissory notes were
issued in the amount of $2,395,835 in connection with the Series B financing.
In October 1999, the notes were converted into 766,667 shares of preferred
Series B stock.

   In March 2000, the Company designated 4,000,000 shares of preferred stock as
Series C preferred stock and then issued 2,522,250 shares of Series C preferred
stock in a private placement offering for gross cash proceeds of $30,000,000.

   In conjunction with the issuance of Series C preferred stock, the Company
issued a $10,000,000 note payable. This note automatically converts into
840,750 shares of Series C preferred stock upon the occurrence of certain
events. Should the events not occur, the principal amount of the notes plus
accrued interest at 7% become due in May 2000.

   Each share of Series A, Series B and Series C preferred stock is convertible
into one share of common stock at the option of the holder, subject to certain
antidilutive adjustments, in accordance with the conversion formula provided in
the Company's certificate of incorporation (currently on a 1:1 ratio).
Outstanding preferred shares automatically convert into common stock upon the
closing of an initial public offering of the Company's common stock in which
gross proceeds exceed $25.0 million with a per share price of not less than
$17.84 per share. Holders of each share of preferred stock are entitled to the
number of votes per share that would be equivalent to the number of shares of
common stock into which a share of preferred stock is convertible and are
entitled to dividends if and when declared by the board of directors. No
dividends have been declared. In the event of any consolidation, merger, or
liquidation, the holders of the Series A, Series B and Series C preferred stock
shall be entitled to receive $1.05, $3.125 and $11.89, respectively, per share
of preferred stock plus cumulative dividends, if and when declared, at the
annual rate of 8%. The Company granted the preferred stockholders certain
registration rights and also agreed not to carry out certain actions without
prior approval of the holders of not less than two-thirds of the outstanding
preferred shares, voting together as a single class.

  (c) Common Stock

   In October 1998, the Company issued to its initial investor 4,000,000 shares
of common stock at a price of $0.10 per share for an aggregate purchase price
of $400,000. In March 1999, in connection with the issuance of Series A
preferred stock, the Company's initial investor exchanged 3,000,000 shares of
common stock for 285,714 shares of Series A preferred stock.

   The Company and its common and preferred Series A, Series B and Series C
stockholders entered into an agreement, which, among other issues, addresses
election of directors, restrictions

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

on transfer of equity securities by stockholders, sales of new securities by
the Company, and covenants related to transfer of shares of the Company's
stock. All provisions of the agreement, with the exception of covenants related
to transfer of shares, expire upon the closing of an initial public offering.

  (d) Equity Incentive Plan

   In February 1999, the Company adopted the 1999 Equity Incentive Plan (the
1999 Plan) under which an aggregate of 5,000,000 shares of common stock was
reserved for grants to employees, directors, and independent contractors. Stock
awards may be designated as incentive stock options, nonstatutory stock
options, stock appreciation rights, stock bonuses, and rights to acquire
restricted stock. Incentive stock options may be granted only to employees. In
September 1999, the Company authorized an additional 2,400,000 shares of common
stock increasing the total common shares reserved under the 1999 Plan to
7,400,000.

   The Board of Directors determines the option price for stock options granted
under the 1999 Plan. Options expire ten years from the date of grant and
generally vest annually over a four-year period. Certain initial options
granted in 1999 were granted with a portion of the shares vesting immediately
on the date of grant. Additionally, the 1999 Plan allows certain optionholders
to exercise unvested options in exchange for stock subject to repurchase rights
of the Company. These repurchase rights would lapse over the original vesting
schedule of the options. As of December 31, 1999, no unvested options had been
exercised under these provisions.

   The following table summarizes the Company's stock option activity:

  (e) Stock-based Compensation

   The Company applies APB Opinion No. 25 in accounting for options granted to
employees under its 1999 Plan. In 1999, the Company issued certain options to
employees under the 1999 Plan with exercise prices less than the deemed fair
value of the underlying common stock for financial reporting purposes on the
date of grant and recorded an aggregate of $3,292,115 as deferred stock
compensation. This deferred stock-based compensation is being recognized as
compensation expense over the options' vesting period. The Company recognized
compensation expense of $452,506 associated with these options during the year
ended December 31, 1999, of which $284,053, $114,776, and $53,677 is reported
on the accompanying statement of operations in selling and marketing,
technology and development, and general and administrative expense,
respectively.

   Under SFAS 123, the per share weighted-average fair value on the date of
grant of stock options granted to employees during 1999 was $0.03 and $4.59,
respectively, for options with the exercise prices equal to the deemed fair
value of common stock and exercise prices less than the deemed fair value of
common stock. The per share weighted average fair value was calculated using
the minimum value method with the following weighted average assumptions:
expected life of 4 years, no dividend yield and a risk free interest rate of
5.5%. If the Company had elected to recognize compensation cost based upon the
per share weighted average fair value of the employee options, net loss and net
loss per common share would have been as follows:

  (f) Approval of New Employee Stock Plans

   In March of 2000, the Board of Directors adopted the 2000 Equity Incentive
Plan (2000 Plan). The 2000 Plan serves as the successor program to the
Company's 1999 Plan. A total of 4,500,000 shares of common stock have been
reserved for issuance under the 2000 Plan. The 2000 Plan will become effective
upon completion of the Company's IPO, and no further option grants will be made
under the 1999 Plan.

   In February of 2000, the Board of Directors adopted the 2000 Employee Stock
Purchase Plan (ESPP). The ESPP allows eligible employees to purchase shares of
common stock, at semi-annual intervals, with their accumulated payroll
deductions. The Company has initially reserved 250,000 shares for purchase
under this plan.

(9) Income Taxes

   The Company did not provide any current or deferred United States federal
income tax provision or benefit for any of the periods presented because it has
experienced operating losses since its inception. The Company provided a full
valuation allowance on net deferred tax assets, consisting primarily of net
operating loss carryforwards and research and development credit carryforwards,
because of the uncertainty regarding their realizability.

   As of December 31, 1998 and December 31, 1999, the Company had approximately
$12,000 and $35.8 million, respectively, of federal tax net operating loss
carryforwards, which begin to expire in 2018. The Company's utilization of its
net operating loss carryforwards may be limited pursuant to the Tax Reform Act
of 1986, due to cumulative changes in ownership in excess of 50%, as defined.

   Deferred tax assets reflect the differences between the carrying amounts of
assets and liabilities for financial reporting purposes and the amounts used
for income tax purposes together with the tax affect of loss carryforwards and
tax credits. Significant items giving rise to deferred tax assets and deferred
tax liabilities are as follows:

(10) Related Party Transactions

and other services with a company in which the majority shareholder of the
Company has a minority ownership interest. Total costs for these services was
approximately $30,000 in 1999.

   In 1999, the Company entered into advertising and promotion arrangements
with various entities affiliated through common ownership. Under these

ITEM 14. Indemnification of Directors and Officers

   Section 145 of the Delaware General Corporation Law authorizes a court to
award or a corporation's board of directors to grant indemnification to
directors and officers in terms sufficiently broad to permit such
indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act. Our
Certificate of Incorporation provides for mandatory indemnification of our
directors to the fullest extent of the Delaware General Corporation Law. In
addition, our Bylaws provide for mandatory indemnification of our directors and
officers and permissible indemnification of employees and other agents to the
maximum extent permitted by the Delaware General Corporation Law. These
provisions, however, do not eliminate the directors' fiduciary duty to Mercata.
In addition, each director will continue to be subject to liability for breach
of the director's duty of loyalty to Mercata, for acts or omissions not in good
faith or involving intentional misconduct, for knowing violations of law, for
actions leading to improper personal benefit to the director and for payment of

ITEM 17. Undertakings

   Mercata hereby undertakes to provide to the Underwriters at the closing
specified in the Underwriting Agreement, certificates in such denominations and
registered in such names as required by the Underwriters to permit prompt
delivery to each purchaser.

   Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers and controlling persons of Mercata pursuant to
the Delaware General Corporation Law, the

                                      II-4
<PAGE>

Certificate of Incorporation or the Bylaws of Mercata, Indemnification
Agreements entered into between Mercata and its officers and directors, the
Underwriting Agreement, or otherwise, Mercata has been advised that in the
opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Act and is, therefore, unenforceable.
In the event that a claim for indemnification against such liabilities (other
than the payment by Mercata of expenses incurred or paid by a director,
officer, or controlling person of Mercata 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, Mercata
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 of whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.

   Mercata hereby undertakes that:

     (1) For purposes of determining any liability under the Act, the
  information omitted from the form of prospectus filed as part of this
  Registration Statement in reliance upon Rule 430A and contained in a form
  of prospectus filed by Mercata pursuant to Rule 424(b)(1) or (4) or 497(h)
  under the 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 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.

The name of the corporation is Mercata, Inc. (the "Corporation" or the

     The address of the registered office of the Corporation in the State of

               30 Old Rudnick Lane

                                     III.

     The purpose of the Corporation is to engage in any lawful act or activity
for which a corporation may be organized under the General Corporation Law of

                                      IV.

     A.  This Corporation is authorized to issue two classes of stock to be
designated, respectively, "Common Stock" and "Preferred Stock."  The total
number of shares which the Corporation is authorized to issue is seventy million
(70,000,000) shares, forty million (40,000,000) shares of which shall be Common
Stock (the "Common Stock") and thirty million (30,000,000) shares of which shall
be Preferred Stock (the "Preferred Stock").  The Preferred Stock shall have a
par value of one tenth of a cent ($0.001) per share and the Common Stock shall
have a par value of one tenth of a cent ($0.001) per share.

                                       1.
<PAGE>

     B.  The number of authorized shares of Common Stock may be increased or
decreased (but not below the number of shares of Common Stock then outstanding)
by the affirmative vote of the holders of a majority of the stock of the
Corporation (voting together on an as-if-converted basis).

     C.  Fourteen million (14,000,000) of the authorized shares of Preferred
Stock are hereby designated "Series A Preferred Stock," twelve million
(12,000,000) of the authorized shares of Preferred Stock are hereby designated
"Series B Preferred Stock" and four million (4,000,000) of the authorized shares
of Preferred Stock are hereby designated "Series C Preferred Stock"
(collectively, the "Series Preferred").

     D.  The rights, preferences, privileges, restrictions and other matters
relating to the Series Preferred are as follows:

          1.   Dividend Rights.

               (a)  Holders of Series Preferred, in preference to the holders of
any other stock of the Company ("Junior Stock"), shall be entitled to receive,
when and as declared by the Board of Directors, but only out of funds that are
legally available therefor, cash dividends at the rate of eight percent (8%) of
the Original Issue Price (as defined below) per annum on each outstanding share
of Series Preferred (as adjusted for any stock dividends, combinations, splits,
recapitalizations and the like with respect to such shares). The "Original Issue
Price" of the Series A Preferred Stock, the Series B Preferred Stock and the
Series C Preferred Stock shall be one dollar and five cents ($1.05) per share,
three dollars twelve and one-half cents ($3.125) per share and eleven dollars
and eighty-nine and four thousand one hundred forty-two ten-thousands cents
($11.894142) per share, respectively. Such dividends shall be payable only when,
as and if declared by the Board of Directors and shall be non-cumulative.

               (b)  So long as any shares of Series Preferred shall be
outstanding, no dividend, whether in cash or property, shall be paid or
declared, nor shall any other distribution be made, on any Junior Stock, nor
shall any shares of any Junior Stock of the Company be purchased, redeemed, or
otherwise acquired for value by the Company (except for acquisitions of Common
Stock by the Company pursuant to agreements which permit the Company to
repurchase such shares upon termination of services to the Company or in
exercise of the Company's right of first refusal upon a proposed transfer) until
all dividends (set forth in Section 1(a) above) on the Series Preferred shall
have been paid or declared and set apart. In the event dividends are paid on any
share of Common Stock, an additional dividend shall be paid with respect to all
outstanding shares of Series Preferred in an amount equal per share (on an
as-if-converted to Common Stock basis) to the amount paid or set aside for each
share of Common Stock. The provisions of this Section 1(b) shall not, however,
apply to (i) a dividend payable in Common Stock, (ii) the acquisition of shares
of any Junior Stock in exchange for shares of any other Junior Stock, or (iii)
any repurchase of any outstanding securities of the Company that is unanimously
approved by the Company's Board of Directors.

                                       2.
<PAGE>

          2.   Voting Rights.

               (a)  General Rights.  Except as otherwise provided herein or as
required by law, the Series Preferred shall be voted equally with the shares of
the Common Stock of the Company and not as a separate class, at any annual or
special meeting of stockholders of the Company, and may act by written consent
in the same manner as the Common Stock, in either case upon the following basis:
each holder of shares of Series Preferred shall be entitled to such number of
votes as shall be equal to the whole number of shares of Common Stock into which
such holder's aggregate number of shares of Series Preferred are convertible
(pursuant to Section 4 hereof) immediately after the close of business on the
record date fixed for such meeting or the effective date of such written
consent.

               (b)  Separate Vote of Series Preferred.  For so long as at least
ten million (10,000,000) shares of Series Preferred (subject to adjustment for
any stock split, reverse stock split or other similar event affecting the Series
Preferred) remain outstanding, in addition to any other vote or consent required
herein or by law, the vote or written consent of the holders of at least a
majority of the outstanding Series Preferred shall be necessary for effecting or
validating the following actions:

                    (i)    Any amendment, alteration, or repeal of any provision
of the Certificate of Incorporation or Bylaws of the Company (including any
filing of a Certificate of Designation), that alters or changes the voting
powers, preferences, or other special rights or privileges, or restrictions of
the Series Preferred (including by way of a merger or consolidation).

                    (ii)   Any increase or decrease (other than by redemption or
conversion) in the authorized number of shares of Common Stock or Preferred
Stock;

                    (iii)  Any authorization or any designation, whether by
reclassification or otherwise, of any new class or series of stock or any other
securities convertible into equity securities of the Company ranking on a parity
with or senior to the Series Preferred in right of redemption, liquidation
preference, voting or dividends or any increase in the authorized or designated
number of any such new class or series;

                    (iv)   Any redemption, repurchase, payment of dividends or
other distributions with respect to Junior Stock (except for acquisitions of
Common Stock by the Company pursuant to agreements which permit the Company to
repurchase such shares upon termination of services to the Company or in
exercise of the Company's right of first refusal upon a proposed transfer);

                    (v)    Any agreement by the Company or its stockholders
regarding an Asset Transfer or Acquisition (each as defined in Section 3(c));

                    (vi)   Any action that results in the payment or declaration
of a dividend on any shares of Common Stock or Preferred Stock;

                                       3.
<PAGE>

                    (vii)  Any voluntary dissolution or liquidation of the
Company; or

                    (viii) Any increase or decrease in the authorized number of
members of the Company's Board of Directors.

               (c)  Separate Votes of Series B Preferred Stock and Series C
Preferred Stock. For so long as at least an aggregate of six million (6,000,000)
shares of Series B Preferred Stock and/or Series C Preferred Stock (subject to
adjustment for any stock split, reverse stock split or other similar event
affecting the Series B Preferred Stock or the Series C Preferred Stock) remain
outstanding, in addition to any other vote or consent required herein or by law,
the vote or written consent of the holders of at least a majority of the
outstanding Series B Preferred Stock and Series C Preferred Stock voting
together as a combined class shall be necessary for effecting or validating the
following actions:

                    (i)    Any amendment, alteration, or repeal of any provision
of the Certificate of Incorporation or Bylaws of the Company (including any
filing of a Certificate of Designation), that alters or changes the voting
powers, preferences, or other special rights or privileges, or restrictions of
the Series B Preferred Stock or the Series C Preferred Stock (including by way
of a merger or consolidation).

                    (ii)   Any authorization or any designation, whether by
reclassification or otherwise, of any new class or series of stock or any other
securities convertible into equity securities of the Company ranking on a parity
with or senior to the Series B Preferred or the Series C Preferred Stock in
right of redemption, liquidation preference, voting or dividends or any increase
in the authorized or designated number of any such new class or series;

                    (iii)  Any redemption, repurchase, payment of dividends or
other distributions with respect to Junior Stock (except for acquisitions of
Common Stock by the Company pursuant to agreements which permit the Company to
repurchase such shares upon termination of services to the Company or in
exercise of the Company's right of first refusal upon a proposed transfer);

                    (iv)   Any agreement by the Company or its stockholders
regarding an Asset Transfer or Acquisition (each as defined in Section 3(c)).

               (d)  Election of Board of Directors. For so long as at least ten
million (10,000,000) shares of Series Preferred remain outstanding (subject to
adjustment for any stock split, reverse stock split or similar event affecting
the Series Preferred) (i) the holders of Series A Preferred Stock, voting as a
separate class, shall be entitled to elect two (2) members of the Company's
Board of Directors at each meeting or pursuant to each consent of the Company's
stockholders for the election of directors, and to remove from office such
directors and to fill any vacancy caused by the resignation, death or removal of
such directors; (ii) the holders of Series B Preferred Stock, voting as a
separate class, shall be entitled to elect one (1) member of the Company's Board
of Directors at each meeting or pursuant to each consent of the Company's

                                       4.
<PAGE>

stockholders for the election of directors, and to remove from office such
director and to fill any vacancy caused by the registration, death or removal of
such director; (iii) the holders of Common Stock, voting as a separate class,
shall be entitled to elect two (2) members of the Board of Directors at each
meeting or pursuant to each consent of the Company's stockholders for the
election of directors, and to remove from office such directors and to fill any
vacancy caused by the resignation, death or removal of such directors; and (iv)
the holders of Common Stock and Series Preferred, voting together as a single
class on an as-if-converted basis, shall be entitled to elect all remaining
members of the Board of Directors at each meeting or pursuant to each consent of
the Company's stockholders for the election of directors, and to remove from
office such directors and to fill any vacancy caused by the resignation, death
or removal of such directors.

          3.   Liquidation Rights.

               (a)  Upon any liquidation, dissolution, or winding up of the
Company, whether voluntary or involuntary, before any distribution or payment
shall be made to the holders of any Junior Stock, the holders of Series
Preferred shall be entitled to be paid out of the assets of the Company an
amount per share of Series Preferred equal to the Original Issue Price plus all
declared and unpaid dividends on the Series Preferred (as adjusted for any stock
dividends, combinations, splits, recapitalizations and the like with respect to
such shares) for each share of Series Preferred held by them. If, upon any such
liquidation, distribution, or winding up, the assets of the Company shall be
insufficient to make payment in full to all holders of Series Preferred of the
liquidation preference set forth in this Section 3(a), then such assets shall be
distributed among the holders of Series Preferred at the time outstanding,
ratably in proportion to the full amounts to which they would otherwise be
respectively entitled.

               (b)  After the payment of the full liquidation preference of the
Series Preferred as set forth in Section 3(a) above, the assets of the Company
legally available for distribution, if any, shall be distributed ratably to the
holders of the Common Stock and Series Preferred on an as-if-converted to Common
Stock basis until such time as the holders of Series Preferred have received
pursuant to Section 3(a) above and this Section 3(b) in aggregate an amount per
share of Series Preferred equal to three (3) times the Original Issue Price (as
adjusted for any stock, dividends, combinations, splits, recapitalizations and
the like with respect to such shares); thereafter the remaining assets of the
Company legally available for distribution, if any, shall be distributed ratably
to the holders of the Common Stock.

               (c)  The following events shall be considered a liquidation under
this Section:

                    (i)    any consolidation or merger of the Company with or
into any other corporation or other entity or person, or any other corporate
reorganization, in which the stockholders of the Company immediately prior to
such consolidation, merger or reorganization, own less than 50% of the Company's
voting power immediately after such consolidation, merger or reorganization, or
any transaction or series of related transactions to which the Company is a
party in which in excess of fifty percent (50%) of the Company's voting

                                       5.
<PAGE>

power is transferred, excluding any consolidation or merger effected exclusively
to change the domicile of the Company (an "Acquisition"); or

                    (ii)   a sale, lease or other disposition of all or
substantially all of the assets of the Company (an "Asset Transfer").

                    (iii)  In any of such events, if the consideration received
by this corporation is other than cash, its value will be deemed its fair market
value as determined in good faith by the Board of Directors. Any securities
shall be valued as follows:

                           (A)  Securities not subject to investment letter or
other similar restrictions on free marketability covered by (B) below:

                                (1)  If traded on a securities exchange or
through the Nasdaq National Market, the value shall be deemed to be the average
of the closing prices of the securities on such quotation system over the thirty
(30) day period ending three (3) days prior to the closing;

                                (2)  If actively traded over-the-counter, the
value shall be deemed to be the average of the closing bid or sale prices
(whichever is applicable) over the thirty (30) day period ending three (3) days
prior to the closing; and

                                (3)  If there is no active public market, the
value shall be the fair market value thereof, as determined by the Board of
Directors.

                           (B)  The method of valuation of securities subject to
investment letter or other restrictions on free marketability (other than
restrictions arising solely by virtue of a shareholder's status as an affiliate
or former affiliate) shall be to make an appropriate discount from the market
value determined as above in (A) (1), (2) or (3) to reflect the approximate fair
market value thereof, as determined by the Board of Directors.

          4.   Conversion Rights.

               The holders of the Series Preferred shall have the following
rights with respect to the conversion of the Series Preferred into shares of
Common Stock (the "Conversion Rights"):

               (a)  Optional Conversion.  Subject to and in compliance with the
provisions of this Section 4, any shares of Series Preferred may, at the option
of the holder, be converted at any time into fully-paid and nonassessable shares
of Common Stock. The number of shares of Common Stock to which a holder of
Series Preferred shall be entitled upon conversion shall be the product obtained
by multiplying the "Series Preferred Conversion Rate" then in effect (determined
as provided in Section 4(b)) by the number of shares of Series Preferred being
converted.

               (b)  Series Preferred Conversion Rate.  The conversion rate in
effect at any time for conversion of the Series Preferred (the "Series Preferred
Conversion Rate") shall

                                       6.
<PAGE>

be the quotient obtained by dividing the Original Issue Price of the Series
Preferred by the "Series Preferred Conversion Price," calculated as provided in
Section 4(c).

               (c)  Series Preferred Conversion Price.  The conversion price for
the Series Preferred shall initially be the Original Issue Price of the Series
Preferred (the "Series Preferred Conversion Price"). Such initial Series
Preferred Conversion Price shall be adjusted from time to time in accordance
with this Section 4. All references to the Series Preferred Conversion Price
herein shall mean the Series Preferred Conversion Price as so adjusted.

               (d)  Mechanics of Conversion. Each holder of Series Preferred who
desires to convert the same into shares of Common Stock pursuant to this Section
4 shall surrender the certificate or certificates therefor, duly endorsed, at
the office of the Company or any transfer agent for the Series Preferred, and
shall give written notice to the Company at such office that such holder elects
to convert the same. Such notice shall state the number of shares of Series
Preferred being converted. Thereupon, the Company shall promptly issue and
deliver at such office to such holder a certificate or certificates for the
number of shares of Common Stock to which such holder is entitled and shall
promptly pay (i) in cash or, to the extent sufficient funds are not then legally
available therefor, in Common Stock (at the Common Stock's fair market value
determined by the Board of Directors as of the date of such conversion), any
declared and unpaid dividends on the shares of Series Preferred being converted
and (ii) in cash (at the Common Stock's fair market value determined by the
Board of Directors as of the date of conversion) the value of any fractional
share of Common Stock otherwise issuable to any holder of Series Preferred. Such
conversion shall be deemed to have been made at the close of business on the
date of such surrender of the certificates representing the shares of Series
Preferred to be converted, and the person entitled to receive the shares of
Common Stock issuable upon such conversion shall be treated for all purposes as
the record holder of such shares of Common Stock on such date.

               (e)  Adjustment for Stock Splits and Combinations. If the Company
shall at any time or from time to time after the date that the first share of
Series Preferred is issued (the "Original Issue Date") effect a subdivision of
the outstanding Common Stock without a corresponding subdivision of the
Preferred Stock, the Series Preferred Conversion Price in effect immediately
before that subdivision shall be proportionately decreased. Conversely, if the
Company shall at any time or from time to time after the Original Issue Date
combine the outstanding shares of Common Stock into a smaller number of shares
without a corresponding combination of the Preferred Stock, the Series Preferred
Conversion Price in effect immediately before the combination shall be
proportionately increased. Any adjustment under this Section 4(e) shall become
effective at the close of business on the date the subdivision or combination
becomes effective.

               (f)  Adjustment for Common Stock Dividends and Distributions. If
the Company at any time or from time to time after the Original Issue Date
makes, or fixes a record date for the determination of holders of Common Stock
entitled to receive, a dividend or other distribution payable in additional
shares of Common Stock, in each such event the Series Preferred Conversion Price
that is then in effect shall be decreased as of the time of such issuance or, in
the event such record date is fixed, as of the close of business on such record
date, by

                                       7.
<PAGE>

multiplying the Series Preferred Conversion Price then in effect by a fraction
(i) the numerator of which is the total number of shares of Common Stock issued
and outstanding immediately prior to the time of such issuance or the close of
business on such record date, and (ii) the denominator of which is the total
number of shares of Common Stock issued and outstanding immediately prior to the
time of such issuance or the close of business on such record date plus the
number of shares of Common Stock issuable in payment of such dividend or
distribution; provided, however, that if such record date is fixed and such
dividend is not fully paid or if such distribution is not fully made on the date
fixed therefor, the Series Preferred Conversion Price shall be recomputed
accordingly as of the close of business on such record date and thereafter the
Series Preferred Conversion Price shall be adjusted pursuant to this Section
4(f) to reflect the actual payment of such dividend or distribution.

               (g)  Adjustment for Reclassification, Exchange and Substitution.
If at any time or from time to time after the Original Issue Date, the Common
Stock issuable upon the conversion of the Series Preferred is changed into the
same or a different number of shares of any class or classes of stock, whether
by recapitalization, reclassification or otherwise (other than an Acquisition or
Asset Transfer as defined in Section 3(c) or a subdivision or combination of
shares or stock dividend or a reorganization, merger, consolidation or sale of
assets provided for elsewhere in this Section 4), in any such event each holder
of Series Preferred shall have the right thereafter to convert such stock into
the kind and amount of stock and other securities and property receivable upon
such recapitalization, reclassification or other change by holders of the
maximum number of shares of Common Stock into which such shares of Series
Preferred could have been converted immediately prior to such recapitalization,
reclassification or change, all subject to further adjustment as provided herein
or with respect to such other securities or property by the terms thereof.

               (h)  Reorganizations, Mergers, Consolidations or Sales of Assets.
If at any time or from time to time after the Original Issue Date, there is a
capital reorganization of the Common Stock (other than an Acquisition or Asset
Transfer as defined in Section 3(c) or a recapitalization, subdivision,
combination, reclassification, exchange or substitution of shares provided for
elsewhere in this Section 4), as a part of such capital reorganization,
provision shall be made so that the holders of the Series Preferred shall
thereafter be entitled to receive upon conversion of the Series Preferred the
number of shares of stock or other securities or property of the Company to
which a holder of the number of shares of Common Stock deliverable upon
conversion would have been entitled on such capital reorganization, subject to
adjustment in respect of such stock or securities by the terms thereof. In any
such case, appropriate adjustment shall be made in the application of the
provisions of this Section 4 with respect to the rights of the holders of Series
Preferred after the capital reorganization to the end that the provisions of
this Section 4 (including adjustment of the Series Preferred Conversion Price
then in effect and the number of shares issuable upon conversion of the Series
Preferred) shall be applicable after that event and be as nearly equivalent as
practicable.

               (i)  Sale of Shares Below Series Preferred Conversion Price.

                    (i)  If at any time or from time to time after the Original
Issue Date, the Company issues or sells, or is deemed by the express provisions
of this subsection (i) to

                                       8.
<PAGE>

have issued or sold, Additional Shares of Common Stock (as defined in subsection
(i)(iv) below), other than as a dividend or other distribution on any class of
stock as provided in Section 4(f) above, and other than a subdivision or
combination of shares of Common Stock as provided in Section 4(e) above, for an
Effective Price (as defined in subsection (i)(iv) below) less than the then
effective Series Preferred Conversion Price, then and in each such case the then
existing Series Preferred Conversion Price shall be reduced, as of the opening
of business on the date of such issue or sale, to a price determined by
multiplying the Series Preferred Conversion Price by a fraction (i) the
numerator of which shall be (A) the number of shares of Common Stock deemed
outstanding (as defined below) immediately prior to such issue or sale, plus (B)
the number of shares of Common Stock which the aggregate consideration received
(as defined in subsection (i)(ii) by the Company for the total number of
Additional Shares of Common Stock so issued would purchase at such Series
Preferred Conversion Price, and (ii) the denominator of which shall be the
number of shares of Common Stock deemed outstanding (as defined below)
immediately prior to such issue or sale plus the total number of Additional
Shares of Common Stock so issued. For the purposes of the preceding sentence,
the number of shares of Common Stock deemed to be outstanding as of a given date
shall be the sum of (A) the number of shares of Common Stock actually
outstanding, (B) the number of shares of Common Stock into which the then
outstanding shares of Series Preferred could be converted if fully converted on
the day immediately preceding the given date, and (C) the number of shares of
Common Stock which could be obtained through the exercise or conversion of all
other rights, options and convertible securities outstanding on the day
immediately preceding the given date.

                    (ii)  For the purpose of making any adjustment required
under this Section 4(i), the consideration received by the Company for any issue
or sale of securities shall (A) to the extent it consists of cash, be computed
at the net amount of cash received by the Company after deduction of any
underwriting or similar commissions, compensation or concessions paid or allowed
by the Company in connection with such issue or sale but without deduction of
any expenses payable by the Company, (B) to the extent it consists of property
other than cash, be computed at the fair value of that property as determined in
good faith by the Board of Directors, and (C) if Additional Shares of Common
Stock, Convertible Securities (as defined in subsection (i)(iii)) or rights or
options to purchase either Additional Shares of Common Stock or Convertible
Securities are issued or sold together with other stock or securities or other
assets of the Company for a consideration which covers both, be computed as the
portion of the consideration so received that may be reasonably determined in
good faith by the Board of Directors to be allocable to such Additional Shares
of Common Stock, Convertible Securities or rights or options.

                    (iii) For the purpose of the adjustment required under this
Section 4(i), if the Company issues or sells (i) stock or other securities
convertible into, Additional Shares of Common Stock (such convertible stock or
securities being herein referred to as "Convertible Securities") or (ii) rights
or options for the purchase of Additional Shares of Common Stock or Convertible
Securities and if the Effective Price of such Additional Shares of Common Stock
is less than the Series Preferred Conversion Price, in each case the Company
shall be deemed to have issued at the time of the issuance of such rights or
options or Convertible Securities the maximum number of Additional Shares of
Common Stock issuable upon exercise or conversion thereof and to have received
as consideration for the issuance of such shares an

amount equal to the total amount of the consideration, if any, received by the
Company for the issuance of such rights or options or Convertible Securities,
plus, in the case of such rights or options, the minimum amounts of
consideration, if any, payable to the Company upon the exercise of such rights
or options, plus, in the case of Convertible Securities, the minimum amounts of
consideration, if any, payable to the Company (other than by cancellation of
liabilities or obligations evidenced by such Convertible Securities) upon the
conversion thereof; provided that if in the case of Convertible Securities the
minimum amounts of such consideration cannot be ascertained, but are a function
of antidilution or similar protective clauses, the Company shall be deemed to
have received the minimum amounts of consideration without reference to such
clauses; provided further that if the minimum amount of consideration payable to
the Company upon the exercise or conversion of rights, options or Convertible
Securities is reduced over time or on the occurrence or non-occurrence of
specified events other than by reason of antidilution adjustments, the Effective
Price shall be recalculated using the figure to which such minimum amount of
consideration is reduced; provided further that if the minimum amount of
consideration payable to the Company upon the exercise or conversion of such
rights, options or Convertible Securities is subsequently increased, the
Effective Price shall be again recalculated using the increased minimum amount
of consideration payable to the Company upon the exercise or conversion of such
rights, options or Convertible Securities. No further adjustment of the Series
Preferred Conversion Price, as adjusted upon the issuance of such rights,
options or Convertible Securities, shall be made as a result of the actual
issuance of Additional Shares of Common Stock on the exercise of any such rights
or options or the conversion of any such Convertible Securities. If any such
rights or options or the conversion privilege represented by any such
Convertible Securities shall expire without having been exercised, the Series
Preferred Conversion Price as adjusted upon the issuance of such rights, options
or Convertible Securities shall be readjusted to the Series Preferred Conversion
Price which would have been in effect had an adjustment been made on the basis
that the only Additional Shares of Common Stock so issued were the Additional
Shares of Common Stock, if any, actually issued or sold on the exercise of such
rights or options or rights of conversion of such Convertible Securities, and
such Additional Shares of Common Stock, if any, were issued or sold for the
consideration actually received by the Company upon such exercise, plus the
consideration, if any, actually received by the Company for the granting of all
such rights or options, whether or not exercised, plus the consideration
received for issuing or selling the Convertible Securities actually converted,
plus the consideration, if any, actually received by the Company (other than by
cancellation of liabilities or obligations evidenced by such Convertible
Securities) on the conversion of such Convertible Securities, provided that such
readjustment shall not apply to prior conversions of Series Preferred.

                    (iv)  "Additional Shares of Common Stock" shall mean all
shares of Common Stock issued by the Company or deemed to be issued pursuant to
this Section 4(i), other than (A) shares of Common Stock issued upon conversion
of the Series Preferred; (B) shares of Common Stock and/or options, warrants or
other Common Stock purchase rights, and the Common Stock issued pursuant to such
options, warrants or other rights (as adjusted for any stock dividends,
combinations, splits, recapitalizations and the like) after the Original Issue
Date to employees, officers or directors of, or consultants or advisors to the
Company or any subsidiary pursuant to stock purchase or stock option plans or
other

                                      10.
<PAGE>

arrangements that are approved by the Board; (C) shares of Common Stock issued
pursuant to the exercise of options, warrants or convertible securities
outstanding as of the Original Issue Date, (D) shares of Common Stock and/or
options, warrants or other Common Stock purchase rights, and the Common Stock
issued pursuant to such options, warrants or other rights issued for
consideration other than cash pursuant to a merger, consolidation, acquisition
or similar business combination approved by the Board and (E) shares of Common
Stock issued pursuant to any equipment leasing arrangement, or debt financing
from a bank or similar financial institution approved by the Board. References
to Common Stock in the subsections of this clause (iv) above shall mean all
shares of Common Stock issued by the Company or deemed to be issued pursuant to
this Section 4(i). The "Effective Price" of Additional Shares of Common Stock
shall mean the quotient determined by dividing the total number of Additional
Shares of Common Stock issued or sold, or deemed to have been issued or sold by
the Company under this Section 4(i), into the aggregate consideration received,
or deemed to have been received by the Company for such issue under this Section
4(i), for such Additional Shares of Common Stock.

               (j)  Certificate of Adjustment. In each case of an adjustment or
readjustment of the Series Preferred Conversion Price for the number of shares
of Common Stock or other securities issuable upon conversion of the Series
Preferred, if the Series Preferred is then convertible pursuant to this Section
4, the Company, at its expense, shall compute such adjustment or readjustment in
accordance with the provisions hereof and prepare a certificate showing such
adjustment or readjustment, and shall mail such certificate, by first class
mail, postage prepaid, to each registered holder of Series Preferred at the
holder's address as shown in the Company's books. The certificate shall set
forth such adjustment or readjustment, showing in detail the facts upon which
such adjustment or readjustment is based, including a statement of (i) the
consideration received or deemed to be received by the Company for any
Additional Shares of Common Stock issued or sold or deemed to have been issued
or sold, (ii) the Series Preferred Conversion Price at the time in effect, (iii)
the number of Additional Shares of Common Stock and (iv) the type and amount, if
any, of other property which at the time would be received upon conversion of
the Series Preferred.

               (k)  Notices of Record Date. Upon (i) any taking by the Company
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 or
other distribution, or (ii) any Acquisition (as defined in Section 3(c)) or
other capital reorganization of the Company, any reclassification or
recapitalization of the capital stock of the Company, any merger or
consolidation of the Company with or into any other corporation, or any Asset
Transfer (as defined in Section 3(c)), or any voluntary or involuntary
dissolution, liquidation or winding up of the Company, the Company shall mail to
each holder of Series Preferred at least ten (10) days prior to the record date
specified therein (or such shorter period approved by a majority of the
outstanding Series Preferred) a notice specifying (A) the date on which any such
record is to be taken for the purpose of such dividend or distribution and a
description of such dividend or distribution, (B) the date on which any such
Acquisition, reorganization, reclassification, transfer, consolidation, merger,
Asset Transfer, dissolution, liquidation or winding up is expected to become
effective, and (C) the date, if any, that is to be fixed as to when the holders
of record of Common Stock (or other securities) shall be entitled to exchange
their shares of Common Stock (or other securities) for securities or other
property deliverable upon such Acquisition, reorganization,

                                      11.
<PAGE>

reclassification, transfer, consolidation, merger, Asset Transfer, dissolution,
liquidation or winding up.

               (l)  Automatic Conversion.

                    (i)  Each share of Series Preferred shall automatically be
converted into shares of Common Stock, based on the then-effective Series
Preferred Conversion Price, (A) at any time upon the affirmative election of the
holders of at least a majority of the outstanding shares of the Series A
Preferred Stock and of the holders of at least a majority of the outstanding
shares of the Series B Preferred Stock and Series C Preferred Stock, voting
together as a combined class, or (B) immediately upon the closing of a firmly
underwritten public offering pursuant to an effective registration statement
under the Securities Act of 1933, as amended, covering the offer and sale of
Common Stock for the account of the Company in which (i) the per share price is
at least $17.84 (as adjusted for stock splits, dividends, recapitalizations and
the like), and (ii) the gross cash proceeds to the Company (before underwriting
discounts, commissions and fees) are at least $25,000,000. Upon such automatic
conversion, any declared and unpaid dividends shall be paid in accordance with
the provisions of Section 4(d).

                    (ii) Upon the occurrence of either of the events specified
in Section 4(l)(i) above, the outstanding shares of Series Preferred shall be
converted automatically without any further action by the holders of such shares
and whether or not the certificates representing such shares are surrendered to
the Company or its transfer agent; provided, however, that the Company shall not
be obligated to issue certificates evidencing the shares of Common Stock
issuable upon such conversion unless the certificates evidencing such shares of
Series Preferred are either delivered to the Company or its transfer agent as
provided below, or the holder notifies the Company or its transfer agent that
such certificates have been lost, stolen or destroyed and executes an agreement
satisfactory to the Company to indemnify the Company from any loss incurred by
it in connection with such certificates. Upon the occurrence of such automatic
conversion of the Series Preferred, the holders of Series Preferred shall
surrender the certificates representing such shares at the office of the Company
or any transfer agent for the Series Preferred. Thereupon, there shall be issued
and delivered to such holder promptly at such office and in its name as shown on
such surrendered certificate or certificates, a certificate or certificates for
the number of shares of Common Stock into which the shares of Series Preferred
surrendered were convertible on the date on which such automatic conversion
occurred, and any declared and unpaid dividends shall be paid in accordance with
the provisions of Section 4(d).

               (m)  Fractional Shares. No fractional shares of Common Stock
shall be issued upon conversion of Series Preferred. All shares of Common Stock
(including fractions thereof) issuable upon conversion of more than one share of
Series Preferred by a holder thereof shall be aggregated for purposes of
determining whether the conversion would result in the issuance of any
fractional share. If, after the aforementioned aggregation, the conversion would
result in the issuance of any fractional share, the Company shall, in lieu of
issuing any fractional share, pay cash equal to the product of such fraction
multiplied by the Common Stock's fair market value (as determined by the Board
of Directors) on the date of conversion.

                                      12.
<PAGE>

               (n)  Reservation of Stock Issuable Upon Conversion. The Company
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 Preferred, 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 Preferred. 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 Preferred, the
Company will take such corporate action as may, in the opinion of its counsel,
be necessary to increase its authorized but unissued shares of Common Stock to
such number of shares as shall be sufficient for such purpose.

               (o)  Notices. Any notice required by the provisions of this
Section 4 shall be in writing and shall be deemed effectively given: (i) upon
personal delivery to the party to be notified, (ii) when sent by confirmed telex
or facsimile if sent during normal business hours of the recipient; if not, then
on the next business day, (iii) five (5) days after having been sent by
registered or certified mail, return receipt requested, postage prepaid, or (iv)
one (1) day after deposit with a nationally recognized overnight courier,
specifying next day delivery, with written verification of receipt. All notices
shall be addressed to each holder of record at the address of such holder
appearing on the books of the Company.

               (p)  Payment of Taxes. The Company will pay all taxes (other than
taxes based upon income) and other governmental charges that may be imposed with
respect to the issue or delivery of shares of Common Stock upon conversion of
shares of Series Preferred, excluding any tax or other charge imposed in
connection with any transfer involved in the issue and delivery of shares of
Common Stock in a name other than that in which the shares of Series Preferred
so converted were registered.

               (q)  No Dilution or Impairment. Without the consent of the
holders of then outstanding Series Preferred as required under Section 2(b), the
Company shall not amend its Restated Certificate of Incorporation or participate
in any reorganization, transfer of assets, consolidation, merger, dissolution,
issue or sale of securities or take any other voluntary action, for the purpose
of avoiding or seeking to avoid the observance or performance of any of the
terms to be observed or performed hereunder by the Company, but shall at all
times in good faith assist in carrying out all such action as may be reasonably
necessary or appropriate in order to protect the conversion rights of the
holders of the Series Preferred against dilution or other impairment.

          5.   No Reissuance of Series Preferred.

               No share or shares of Series Preferred acquired by the
Corporation by reason of redemption, purchase, conversion or otherwise shall be
reissued.

                                      V.

     A.   The liability of the directors for monetary damages shall be
eliminated to the fullest extent under applicable law.

                                      13.
<PAGE>

     B.   Any repeal or modification of this Article V shall only be prospective
and shall not effect the rights under this Article V in effect at the time of
the alleged occurrence of any action or omission to act giving rise to
liability.

                                      VI.

     For the management of the business and for the conduct of the affairs of
the Corporation, and in further definition, limitation and regulation of the
powers of the Corporation, of its directors and of its stockholders or any class
thereof, as the case may be, it is further provided that:

     A.   The management of the business and the conduct of the affairs of the
Corporation shall be vested in its Board of Directors. The number of directors
which shall constitute the whole Board of Directors shall be fixed by the Board
of Directors in the manner provided in the Bylaws.

     B.   Subject to the indemnification provisions in the Bylaws, the Board of
Directors may from time to time make, amend, supplement or repeal the Bylaws;
provided, however, that the stockholders may change or repeal any Bylaw adopted
by the Board of Directors by the affirmative vote of the percentage of holders
of capital stock as provided therein; and, provided further, that no amendment
or supplement to the Bylaws adopted by the Board of Directors shall vary or
conflict with any amendment or supplement thus adopted by the stockholders.

     C.   The directors of the Corporation need not be elected by written ballot
unless the Bylaws so provide.

                       (Incorporated September 23, 1998)

     Tom Van Horn and Jon C. Engman hereby certify that:

     The address of the registered office of the Corporation in the State of
Delaware is:

          CorpAmerica, Inc.
          30 Old Rudnick Lane

          County of Kent

     The name of the Corporation's registered agent at said address is
CorpAmerica, Inc.

                                     III.

     The purpose of this corporation is to engage in any lawful act or activity
for which a corporation may be organized under the General Corporation Law of
the State of Delaware.

                                      IV.

     A.   This corporation is authorized to issue two classes of stock to be
designated, respectively, "Common Stock" and "Preferred Stock."  The total
number of shares which the corporation is authorized to issue is
_________________ (__________) shares.  _______________ (__________) shares
shall be Common Stock, each having a par value of one-tenth of one cent ($.001).
___________ (_________) shares shall be Preferred Stock, each having a par value
of one-tenth of one cent ($.001).

     B.   The Preferred Stock may be issued from time to time in one or more
series.  The Board of Directors is hereby authorized, by filing a certificate (a
"Preferred Stock Designation") pursuant to the Delaware General Corporation Law
("DGCL"), to fix or alter from time to time

                                       1.
<PAGE>

the designation, powers, preferences and rights of the shares of each such
series and the qualifications, limitations or restrictions of any wholly
unissued series of Preferred Stock, and to establish from time to time the
number of shares constituting any such series or any of them; and to increase or
decrease the number of shares of any series subsequent to the issuance of shares
of that series, but not below the number of shares of such series then
outstanding. In case the number of shares of any series shall be decreased in
accordance with the foregoing sentence, the shares constituting such decrease
shall resume the status that they had prior to the adoption of the resolution
originally fixing the number of shares of such series.

                                      V.

     For the management of the business and for the conduct of the affairs of
the corporation, and in further definition, limitation and regulation of the
powers of the corporation, of its directors and of its stockholders or any class
thereof, as the case may be, it is further provided that:

     A.

          1.   The management of the business and the conduct of the affairs of
the corporation shall be vested in its Board of Directors.  The number of
directors which shall constitute the whole Board of Directors shall be fixed
exclusively by one or more resolutions adopted by the Board of Directors.

          2.   Board of Directors

               Subject to the rights of the holders of any series of Preferred
Stock to elect additional directors under specified circumstances, following the
closing of the initial public offering pursuant to an effective registration
statement under the Securities Act of 1933, as amended (the "1933 Act"),
covering the offer and sale of Common Stock to the public (the "Initial Public
Offering"), the directors shall be divided into three classes designated as
Class I, Class II and Class III, respectively. Directors shall be assigned to
each class in accordance with a resolution or resolutions adopted by the Board
of Directors. At the first annual meeting of stockholders following the closing
of the Initial Public Offering, the term of office of the Class I directors
shall expire and Class I directors shall be elected for a full term of three
years. At the second annual meeting of stockholders following the closing of the
Initial Public Offering, the term of office of the Class II directors shall
expire and Class II directors shall be elected for a full term of three years.
At the third annual meeting of stockholders following the closing of the Initial
Public Offering, the term of office of the Class III directors shall expire and
Class III directors shall be elected for a full term of three years. At each
succeeding annual meeting of stockholders, directors shall be elected for a full
term of three years to succeed the directors of the class whose terms expire at
such annual meeting.

     Notwithstanding the foregoing provisions of this section, each director
shall serve until his successor is duly elected and qualified or until his
death, resignation or removal.  No decrease in the number of directors
constituting the Board of Directors shall shorten the term of any incumbent
director.

                                       2.
<PAGE>

          3.   Removal of Directors

               a.   Neither the Board of Directors nor any individual director
may be removed without cause.

               b.   Subject to any limitation imposed by law, any individual
director or directors may be removed with cause by the holders of a majority of
the voting power of the corporation entitled to vote at an election of
directors.

          4.   Vacancies

               a.   Subject to the rights of the holders of any series of
Preferred Stock, any vacancies on the Board of Directors resulting from death,
resignation, disqualification, removal or other causes and any newly created
directorships resulting from any increase in the number of directors, shall,
unless the Board of Directors determines by resolution that any such vacancies
or newly created directorships shall be filled by the stockholders, except as
otherwise provided by law, be filled only by the affirmative vote of a majority
of the directors then in office, even though less than a quorum of the Board of
Directors, and not by the stockholders.  Any director elected in accordance with
the preceding sentence shall hold office for the remainder of the full term of
the director for which the vacancy was created or occurred and until such
director's successor shall have been elected and qualified.

               b.   If at the time of filling any vacancy or any newly created
directorship, the directors then in office shall constitute less than a majority
of the whole board (as constituted immediately prior to any such increase), the
Delaware Court of Chancery may, upon application of any stockholder or
stockholders holding at least ten percent (10%) of the total number of the
shares at the time outstanding having the right to vote for such directors,
summarily order an election to be held to fill any such vacancies or newly
created directorships, or to replace the directors chosen by the directors then
in offices as aforesaid, which election shall be governed by Section 211 of the
DGCL.

     B.

          1.   Bylaw Amendments

               Subject to paragraph (h) of Section 43 of the Bylaws, the Bylaws
may be altered or amended or new Bylaws adopted by the affirmative vote of at
least sixty-six and two-thirds percent (66-2/3%) of the voting power of all of
the then-outstanding shares of the voting stock of the corporation entitled to
vote. The Board of Directors shall also have the power to adopt, amend, or
repeal Bylaws.

          2.   The directors of the corporation need not be elected by written
ballot unless the Bylaws so provide.

          3.   No action shall be taken by the stockholders of the corporation
except at an annual or special meeting of stockholders called in accordance with
the Bylaws or by written consent of stockholders in accordance with the Bylaws
prior to the closing of the Initial Public

                                       3.

Offering and following the closing of the Initial Public Offering no action
shall be taken by the stockholders by written consent.

          4.   Advance notice of stockholder nominations for the election of
directors and of business to be brought by stockholders before any meeting of
the stockholders of the corporation shall be given in the manner provided in the
Bylaws of the corporation.

     A.   The liability of the directors for monetary damages shall be
eliminated to the fullest extent under applicable law.

     B.   Any repeal or modification of this Article VI shall be prospective and
shall not affect the rights under this Article VI in effect at the time of the
alleged occurrence of any act or omission to act giving rise to liability or
indemnification.

                                     VII.

     A.   The corporation reserves the right to amend, alter, change or repeal
any provision contained in this Certificate of Incorporation, in the manner now
or hereafter prescribed by statute, except as provided in paragraph B. of this
Article VII, and all rights conferred upon the stockholders herein are granted
subject to this reservation.

     B.   Notwithstanding any other provisions of this Certificate of
Incorporation or any provision of law which might otherwise permit a lesser vote
or no vote, but in addition to any affirmative vote of the holders of any
particular class or series of the voting stock required by law, this Certificate
of Incorporation or any Preferred Stock Designation, the affirmative vote of the
holders of at least sixty-six and two-thirds percent (66-2/3%) of the voting
power of all of the then-outstanding shares of the voting stock, voting together
as a single class, shall be required to alter, amend or repeal Articles V, VI,
and VII.

                               *    *    *    *

Preferred Stock approved this Restated Certificate of Incorporation by written

                           (A DELAWARE CORPORATION)

                                   ARTICLE I

                                    Offices

     Section 1.   Registered Office. The registered office of the corporation in
the State of Delaware shall be in the City of Dover, County of Kent.

     Section 2.   Other Offices. The corporation shall also have and maintain an
office or principal place of business at such place as may be fixed by the Board
of Directors, and may also have offices at such other places, both within and
without the State of Delaware, as the Board of Directors may from time to time
determine or the business of the corporation may require.

                                Corporate Seal

     Section 3.   Corporate Seal.  The corporate seal shall consist of a die
bearing the name of the corporation and the inscription, "Corporate Seal-
Delaware."  Said seal may be used by causing it or a facsimile thereof to be
impressed or affixed or reproduced or otherwise.

                                  ARTICLE III

                            Stockholders' Meetings

     Section 4.   Place of Meetings.  Meetings of the stockholders of the
corporation shall be held at such place, either within or without the State of
Delaware, as may be designated from time to time by the Board of Directors, or,
if not so designated, then at the principal office of the corporation required
to be maintained pursuant to Section 2 hereof.

     Section 5.   Annual Meeting.

            (a)   The annual meeting of the stockholders of the corporation, for
the purpose of election of directors and for such other business as may lawfully
come before it, shall be held on such date and at such time as may be designated
from time to time by the Board of Directors.

            (b)   At an annual meeting of the stockholders, only such business
shall be conducted as shall have been properly brought before the meeting. To be
properly brought before an annual meeting, business must be: (A) specified in
the notice of meeting (or any

                                      1.
<PAGE>

supplement thereto) given by or at the direction of the Board of Directors, (B)
otherwise properly brought before the meeting by or at the direction of the
Board of Directors, or (C) otherwise properly brought before the meeting by a
stockholder. For business to be properly brought before an annual meeting by a
stockholder, the stockholder must have given timely notice thereof in writing to
the Secretary of the corporation. To be timely, a stockholder's notice must be
delivered to or mailed and received at the principal executive offices of the
corporation not later than the close of business on the sixtieth (60th) day nor
earlier than the close of business on the ninetieth (90th) day prior to the
first anniversary of the preceding year's annual meeting; provided, however,
that in the event that no annual meeting was held in the previous year or the
date of the annual meeting has been changed by more than thirty (30) days from
the date contemplated at the time of the previous year's proxy statement, notice
by the stockholder to be timely must be so received not earlier than the close
of business on the ninetieth (90th) day prior to such annual meeting and not
later than the close of business on the later of the sixtieth (60th) day prior
to such annual meeting or, in the event public announcement of the date of such
annual meeting is first made by the corporation fewer than seventy (70) days
prior to the date of such annual meeting, the close of business on the tenth
(10th) day following the day on which public announcement of the date of such
meeting is first made by the corporation. A stockholder's notice to the
Secretary shall set forth as to each matter the stockholder proposes to bring
before the annual meeting: (i) a brief description of the business desired to be
brought before the annual meeting and the reasons for conducting such business
at the annual meeting, (ii) the name and address, as they appear on the
corporation's books, of the stockholder proposing such business, (iii) the class
and number of shares of the corporation which are beneficially owned by the
stockholder, (iv) any material interest of the stockholder in such business and
(v) any other information that is required to be provided by the stockholder
pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended
(the "1934 Act"), in his capacity as a proponent to a stockholder proposal.
Notwithstanding the foregoing, in order to include information with respect to a
stockholder proposal in the proxy statement and form of proxy for a
stockholders' meeting, stockholders must provide notice as required by the
regulations promulgated under the 1934 Act. Notwithstanding anything in these
Bylaws to the contrary, no business shall be conducted at any annual meeting
except in accordance with the procedures set forth in this paragraph (b). The
chairman of the annual meeting shall, if the facts warrant, determine and
declare at the meeting that business was not properly brought before the meeting
and in accordance with the provisions of this paragraph (b), and, if he should
so determine, he shall so declare at the meeting that any such business not
properly brought before the meeting shall not be transacted.

          (c)  For purposes of this Section 5, "public announcement" shall mean
disclosure in a press release reported by the Dow Jones News Service, Associated
Press or comparable national news service or in a document publicly filed by the
corporation with the Securities and Exchange Commission pursuant to Section 13,
14 or 15(d) of the 1934 Act.

     Section 6.   Special Meetings.

          (a)  Special meetings of the stockholders of the corporation may be
called, for any purpose or purposes, by (i) the Chairman of the Board of
Directors, (ii) the Chief Executive Officer, or (iii) the Board of Directors
pursuant to a resolution adopted by a majority of the total number of authorized
directors (whether or not there exist any vacancies in previously authorized

                                      2.
<PAGE>

directorships at the time any such resolution is presented to the Board of
Directors for adoption) and shall be held at such place, on such date, and at
such time as the Board of Directors shall fix.

          (b)  If a special meeting is properly called by any person or persons
other than the Board of Directors, the request shall be in writing, specifying
the general nature of the business proposed to be transacted, and shall be
delivered personally or sent by registered mail or by telegraphic or other
facsimile transmission to the Chairman of the Board of Directors, the Chief
Executive Officer, or the Secretary of the corporation. No business may be
transacted at such special meeting otherwise than specified in such notice. The
Board of Directors shall determine the time and place of such special meeting,
which shall be held not less than thirty-five (35) nor more than one hundred
twenty (120) days after the date of the receipt of the request. Upon
determination of the time and place of the meeting, the officer receiving the
request shall cause notice to be given to the stockholders entitled to vote, in
accordance with the provisions of Section 7 of these Bylaws. If the notice is
not given within sixty (60) days after the receipt of the request, the person or
persons properly requesting the meeting may set the time and place of the
meeting and give the notice. Nothing contained in this paragraph (b) shall be
construed as limiting, fixing, or affecting the time when a meeting of
stockholders called by action of the Board of Directors may be held.

     Section 7.   Notice of Meetings. Except as otherwise provided by law or the
Certificate of Incorporation, written notice of each meeting of stockholders
shall be given not less than ten (10) nor more than sixty (60) days before the
date of the meeting to each stockholder entitled to vote at such meeting, such
notice to specify the place, date and hour and purpose or purposes of the
meeting. Notice of the time, place and purpose of any meeting of stockholders
may be waived in writing, signed by the person entitled to notice thereof,
either before or after such meeting, and will be waived by any stockholder by
his attendance thereat in person or by proxy, except when the stockholder
attends a meeting for the express purpose of objecting, at the beginning of the
meeting, to the transaction of any business because the meeting is not lawfully
called or convened. Any stockholder so waiving notice of such meeting shall be
bound by the proceedings of any such meeting in all respects as if due notice
thereof had been given.

     Section 8.   Quorum. At all meetings of stockholders, except where
otherwise provided by statute or by the Certificate of Incorporation, or by
these Bylaws, the presence, in person or by proxy duly authorized, of the
holders of a majority of the outstanding shares of stock entitled to vote shall
constitute a quorum for the transaction of business. In the absence of a quorum,
any meeting of stockholders may be adjourned, from time to time, either by the
chairman of the meeting or by vote of the holders of a majority of the shares
represented thereat, but no other business shall be transacted at such meeting.
The stockholders present at a duly called or convened meeting, at which a quorum
is present, may continue to transact business until adjournment, notwithstanding
the withdrawal of enough stockholders to leave less than a quorum. Except as
otherwise provided by law, the Certificate of Incorporation or these Bylaws, all
action taken by the holders of a majority of the vote cast in all matters other
than the election of directors, the affirmative vote of a majority of shares
present in person or represented by proxy at the meeting and entitled to vote on
the subject matter shall be the act of the stockholders. Except as otherwise
provided by statute, the Certificate of Incorporation or these Bylaws, directors
shall be elected by a plurality of the votes of the shares present in person or

                                      3.
<PAGE>

represented by proxy at the meeting and entitled to vote on the election of
directors.  Where a separate vote by a class or classes or series is required,
except where otherwise provided by the statute or by the Certificate of
Incorporation or these Bylaws, a majority of the outstanding shares of such
class or classes or series, present in person or represented by proxy, shall
constitute a quorum entitled to take action with respect to that vote on that
matter and, except where otherwise provided by statute or by the Certificate of
Incorporation or these Bylaws, the affirmative vote of the majority (plurality,
in the case of the election of directors) of the votes cast by the holders of
shares of such class or classes or series shall be the act of such class or
classes or series.

     Section 9.   Adjournment and Notice of Adjourned Meetings.  Any meeting of
stockholders, whether annual or special, may be adjourned from time to time
either by the chairman of the meeting or by the vote of a majority of the shares
casting votes.  When a meeting is adjourned to another time or place, notice
need not be given of the adjourned meeting if the time and place thereof are
announced at the meeting at which the adjournment is taken.  At the adjourned
meeting, the corporation may transact any business which might have been
transacted at the original meeting.  If the adjournment is for more than thirty
(30) days or if after the adjournment a new record date is fixed for the
adjourned meeting, a notice of the adjourned meeting shall be given to each
stockholder of record entitled to vote at the meeting.

     Section 10.  Voting Rights. For the purpose of determining those
stockholders entitled to vote at any meeting of the stockholders, except as
otherwise provided by law, only persons in whose names shares stand on the stock
records of the corporation on the record date, as provided in Section 12 of
these Bylaws, shall be entitled to vote at any meeting of stockholders. Every
person entitled to vote or execute consents shall have the right to do so either
in person or by an agent or agents authorized by a proxy granted in accordance
with Delaware law. An agent so appointed need not be a stockholder. No proxy
shall be voted after three (3) years from its date of creation unless the proxy
provides for a longer period.

     Section 11.  Joint Owners of Stock.  If shares or other securities having
voting power stand of record in the names of two (2) or more persons, whether
fiduciaries, members of a partnership, joint tenants, tenants in common, tenants
by the entirety, or otherwise, or if two (2) or more persons have the same
fiduciary relationship respecting the same shares, unless the Secretary is given
written notice to the contrary and is furnished with a copy of the instrument or
order appointing them or creating the relationship wherein it is so provided,
their acts with respect to voting shall have the following effect:  (a) if only
one (1) votes, his act binds all; (b) if more than one (1) votes, the act of the
majority so voting binds all; (c) if more than one (1) votes, but the vote is
evenly split on any particular matter, each faction may vote the securities in
question proportionally, or may apply to the Delaware Court of Chancery for
relief as provided in the Delaware General Corporation Law, Section 217(b).  If
the instrument filed with the Secretary shows that any such tenancy is held in
unequal interests, a majority or even-split for the purpose of subsection (c)
shall be a majority or even-split in interest.

     Section 12.  List of Stockholders. The Secretary shall prepare and make, at
least ten (10) days before every meeting of stockholders, a complete list of the
stockholders entitled to vote at said meeting, arranged in alphabetical order,
showing the address of each stockholder and the number of shares registered in
the name of each stockholder. Such list shall be open to the

                                      4.
<PAGE>

examination of any stockholder, for any purpose germane to the meeting, during
ordinary business hours, for a period of at least ten (10) days prior to the
meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not
specified, at the place where the meeting is to be held. The list shall be
produced and kept at the time and place of meeting during the whole time thereof
and may be inspected by any stockholder who is present.

     Section 13.  Action Without Meeting.

          (a)  Unless otherwise provided in the Certificate of Incorporation,
any action required by statute to be taken at any annual or special meeting of
the stockholders, or any action which may be taken at any annual or special
meeting of the stockholders, may be taken without a meeting, without prior
notice and without a vote, if a consent in writing, setting forth the action so
taken, shall be signed by the holders of outstanding stock having not less than
the minimum number of votes that would be necessary to authorize or take such
action at a meeting at which all shares entitled to vote thereon were present
and voted.

          (b)  Every written consent shall bear the date of signature of each
stockholder who signs the consent, and no written consent shall be effective to
take the corporate action referred to therein unless, within sixty (60) days of
the earliest dated consent delivered to the corporation in the manner herein
required, written consents signed by a sufficient number of stockholders to take

     Section 15. Number and Term of Office. The authorized number of directors
of the corporation shall be seven (7). Directors need not be stockholders unless

Stock to elect additional directors under specified circumstances, directors
shall be elected at each annual meeting of stockholders for a term of one year.

of Directors determines by resolution that any such vacancies or newly created
directorships shall be filled by stockholders, be filled only by the affirmative
vote of a majority of the directors then in office, even though less than a
quorum of the Board of Directors. Any director elected in accordance with the
preceding sentence shall hold office for the remainder of the full term of the
director for which the vacancy was created or occurred and until such director's

of the whole board (as constituted immediately prior to any such increase), the
Delaware Court of Chancery may, upon application of any stockholder or
stockholders holding at least ten percent (10%) of the total number of the
shares at the time outstanding having the right to vote for such directors,
summarily order an election to be held to fill any such vacancies or newly
created directorships, or to replace the directors chosen by the directors then
in offices as aforesaid, which election shall be governed by Section 211 of the
Delaware General Corporation Law.

     Section 19. Resignation. Any director may resign at any time by delivering
his written resignation to the Secretary, such resignation to specify whether it
will be effective at a particular time, upon receipt by the Secretary or at the
pleasure of the Board of Directors. If no such specification is made, it shall
be deemed effective at the pleasure of the Board of Directors. When one or more
directors shall resign from the Board of Directors, effective at a future date,
a majority of the directors then in office, including those who have so
resigned, shall have power to fill such vacancy or vacancies, the vote thereon
to take effect when such resignation or resignations shall become effective, and
each Director so chosen shall hold office for the unexpired portion of the term
of the Director whose place shall be vacated and until his successor shall have
been duly elected and qualified.

          (a)  Subject to any limitations imposed by applicable law, the Board
of Directors or any director may be removed from office at any time (i) with
cause by the affirmative vote of the holders of a majority of the voting power
of all then-outstanding shares of voting stock of the corporation entitled to

of the Board of Directors, or any committee thereof, however called or noticed,

of this Bylaw may at any time increase or decrease the number of members of a
committee or terminate the existence of a committee. The membership of a
committee member shall terminate on the date of his death or voluntary
resignation from the committee or from the Board of Directors. The Board of
Directors may at any time for any reason remove any individual committee member
and the Board of Directors may fill any committee vacancy created by death,
resignation, removal or increase in the number of members of the committee. The
Board of Directors may designate one or more directors as alternate members of
any committee, who may replace any absent or disqualified member at any meeting
of the committee, and, in addition, in the absence or disqualification of any
member of a committee, the member or members thereof present at any meeting and

committee, upon written notice to the members of such committee of the time and
place of such special meeting given in the manner provided for the giving of
written notice to members of the Board of Directors of the time and place of

any committee may be waived in writing at any time before or after the meeting
and will be waived by any director by attendance thereat, except when the
director attends such special meeting for the express purpose of objecting, at
the beginning of the meeting, to the transaction of any business because the
meeting is not lawfully called or convened.  A majority of the authorized number
of members of any such committee shall constitute a quorum for the transaction

corporation will furnish without charge to each stockholder who so requests the

of certificates representing stock of the same class and series shall be
identical.

issued in place of any certificate or certificates theretofore issued by the
corporation alleged to have been lost, stolen, or destroyed, upon the making of

precedent to the issuance of a new certificate or certificates, the owner of
such lost, stolen, or destroyed certificate or certificates, or his legal
representative, to agree to indemnify the corporation in such manner as it shall
require or to give the corporation a surety bond in such form and amount as it
may direct as indemnity against any claim that may be made against the
corporation with respect to the certificate alleged to have been lost, stolen,
or destroyed.

date shall not precede the date upon which the resolution fixing the record date
is adopted by the Board of Directors, and which record date shall, subject to
applicable law, not be more than sixty (60) nor less than ten (10) days before
the date of such meeting.  If no record date is fixed by the Board of Directors,
the record date for determining stockholders entitled to notice of or to vote at
a meeting of stockholders shall be at the close of business on the day next
preceding the day on which notice is given, or if notice is waived, at the close
of business on the day next preceding the day on which the meeting is held.  A
determination of stockholders of record entitled to notice of or to vote at a
meeting of stockholders shall apply to any adjournment of the meeting; provided,
however, that the Board of Directors may fix a new record date for the adjourned
meeting.

     (b)  In order that the corporation may determine the stockholders entitled
to consent to corporate action in writing without a meeting, the Board of
Directors may fix a record date, which record date shall not precede the date
upon which the resolution fixing the record date is adopted by the Board of
Directors, and which date shall not be more than ten (10) days after the date
upon which the resolution fixing the record date is adopted by the Board of
Directors.  Any stockholder of record seeking to have the stockholders authorize
or take corporate action by written consent shall, by written notice to the
Secretary, request the Board of Directors to fix a record date.  The Board of
Directors shall promptly, but in all events within ten (10) days after the date

principal place of business or an officer or agent of the corporation having
custody of the book in which proceedings of meetings of stockholders are
recorded.  Delivery made to the corporation's registered office shall be by hand
or by certified or registered mail, return receipt requested.  If no record date
has been fixed by the Board of Directors and prior action by the Board of
Directors is required by law, the record date for determining stockholders
entitled to consent to corporate action in writing without a meeting shall be at
the close of business on the day on which the Board of Directors adopts the
resolution taking such prior action.

          (c)  In order that the corporation may determine the stockholders
entitled to receive payment of any dividend or other distribution or allotment
of any rights or the stockholders entitled to exercise any rights in respect of
any change, conversion or exchange of stock, or for the purpose of any other
lawful action, the Board of Directors may fix, in advance, a record date, which
record date shall not precede the date upon which the resolution fixing the
record date is adopted, and which record date shall be not more than sixty (60)
days prior to such action. If no record date is fixed, the record date for
determining stockholders for any such purpose shall be at the close of business
on the day on which the Board of Directors adopts the resolution relating
thereto.

     Section 38.  Registered Stockholders.  The corporation shall be entitled to
recognize the exclusive right of a person registered on its books as the owner
of shares to receive dividends, and to vote as such owner, and shall not be
bound to recognize any equitable or other claim to or interest in such share or
shares on the part of any other person whether or not it shall have express or
other notice thereof, except as otherwise provided by the laws of Delaware.

                                 ARTICLE VIII

                      Other Securities Of The Corporation

     Section 39.  Execution of Other Securities. All bonds, debentures and other
corporate securities of the corporation, other than stock certificates (covered
in Section 34), may be signed by the Chairman of the Board of Directors, the
President or any Vice President, or such other person as may be authorized by
the Board of Directors, and the corporate seal impressed thereon or a facsimile
of such seal imprinted thereon and attested by the signature of the Secretary or
an Assistant Secretary, or the Chief Financial Officer or Treasurer or an
Assistant Treasurer; provided, however, that where any such bond, debenture or
other corporate security shall be authenticated by the manual signature, or
where permissible facsimile signature, of a trustee under an indenture pursuant
to which such bond, debenture or other corporate security shall be issued, the
signatures of the persons signing and attesting the corporate seal on such bond,
debenture or other corporate security may be the imprinted facsimile of the
signatures of such persons. Interest coupons appertaining to any such bond,
debenture or other corporate security, authenticated by a trustee as aforesaid,
shall be signed by the Treasurer or an Assistant Treasurer of the corporation or
such other person as may be authorized by the Board of Directors, or bear
imprinted thereon the facsimile signature of such person. In case any officer
who shall have signed or attested any bond, debenture or other corporate
security, or whose facsimile signature shall appear thereon or on any such
interest coupon, shall have ceased to be such officer before the bond, debenture
or other corporate security so signed or attested shall have been delivered,
such bond, debenture or other corporate security nevertheless may be adopted by
the corporation and issued and delivered as though the person who signed the
same or whose facsimile signature shall have been used thereon had not ceased to
be such officer of the corporation.

     Section 40.  Declaration of Dividends.  Dividends upon the capital stock of
the corporation, subject to the provisions of the Certificate of Incorporation
and applicable law, if any, may be declared by the Board of Directors pursuant
to law at any regular or special meeting.  Dividends may be paid in cash, in

Certificate of Incorporation and applicable law.

     Section 41.  Dividend Reserve. Before payment of any dividend, there may be
set aside out of any funds of the corporation available for dividends such sum
or sums as the Board of Directors from time to time, in their absolute
discretion, think proper as a reserve or reserves to meet contingencies, or for
equalizing dividends, or for repairing or maintaining any property of the
corporation, or for such other purpose as the Board of Directors shall think
conducive to the interests of the corporation, and the Board of Directors may
modify or abolish any such reserve in the manner in which it was created.

                                  ARTICLE XI

                                Indemnification

     Section 43.  Indemnification of Directors, Executive Officers, Other
Officers, Employees and Other Agents.

          (a)  Directors and Officers. The corporation shall indemnify its
directors and officers to the fullest extent not prohibited by the Delaware
General Corporation Law or any other applicable law; provided, however, that the
corporation may modify the extent of such indemnification by individual
contracts with its directors and officers; and, provided, further, that the
corporation shall not be required to indemnify any director or officer in
connection with any proceeding (or part thereof) initiated by such person unless
(i) such indemnification is expressly required to be made by law, (ii) the
proceeding was authorized by the Board of Directors of the corporation, (iii)
such indemnification is provided by the corporation, in its sole discretion,
pursuant to the powers vested in the corporation under the Delaware General
Corporation Law or any other applicable law or (iv) such indemnification is
required to be made under subsection (d).

          (b)  Officers, Employees and Other Agents. The corporation shall have
power to indemnify its officers, employees and other agents as set forth in the
Delaware General Corporation Law or any other applicable law. The Board of
Directors shall have the power to

                                      16.
<PAGE>

delegate the determination of whether indemnification shall be given to any such
person to such officers or other persons as the Board of Directors shall
determine.

          (c)  Expenses. The corporation shall advance to any person who was or
is a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative, by reason of the fact that he is or was a director or officer, of
the corporation, or is or was serving at the request of the corporation as a
director or officer of another corporation, partnership, joint venture, trust or
other enterprise, prior to the final disposition of the proceeding, promptly
following request therefor, all expenses incurred by any director or officer in
connection with such proceeding upon receipt of an undertaking by or on behalf
of such person to repay said amounts if it should be determined ultimately that
such person is not entitled to be indemnified under this Bylaw or otherwise.

     Notwithstanding the foregoing, unless otherwise determined pursuant to
paragraph (e) of this Bylaw, no advance shall be made by the corporation to an
officer of the corporation (except by reason of the fact that such officer is or
was a director of the corporation, in which event this paragraph shall not
apply) in any action, suit or proceeding, whether civil, criminal,
administrative or investigative, if a determination is reasonably and promptly
made (i) by the Board of Directors by a majority vote of a quorum consisting of
directors who were not parties to the proceeding, or (ii) if such quorum is not
obtainable, or, even if obtainable, a quorum of disinterested directors so
directs, by independent legal counsel in a written opinion, that the facts known
to the decision-making party at the time such determination is made demonstrate
clearly and convincingly that such person acted in bad faith or in a manner that
such person did not believe to be in or not opposed to the best interests of the
corporation.

          (d)  Enforcement.  Without the necessity of entering into an express
contract, all rights to indemnification and advances to directors and officers
under this Bylaw shall be deemed to be contractual rights and be effective to
the same extent and as if provided for in a contract between the corporation and
the director or officer.  Any right to indemnification or advances granted by
this Bylaw to a director or officer shall be enforceable by or on behalf of the
person holding such right in any court of competent jurisdiction if (i) the
claim for indemnification or advances is denied, in whole or in part, or (ii) no
disposition of such claim is made within ninety (90) days of request therefor.
The claimant in such enforcement action, if successful in whole or in part,
shall be entitled to be paid also the expense of prosecuting his claim.  In
connection with any claim for indemnification, the corporation shall be entitled
to raise as a defense to any such action that the claimant has not met the
standards of conduct that make it permissible under the Delaware General
Corporation Law or any other applicable law for the corporation to indemnify the
claimant for the amount claimed.  In connection with any claim by an officer of
the corporation (except in any action, suit or proceeding, whether civil,
criminal, administrative or investigative, by reason of the fact that such
officer is or was a director of the corporation) for advances, the corporation
shall be entitled to raise a defense as to any such action clear and convincing
evidence that such person acted in bad faith or in a manner that such person did
not believe to be in or not opposed to the best interests of the corporation, or
with respect to any criminal action or proceeding that such person acted without
reasonable cause to believe that his conduct was lawful.  Neither the failure of
the corporation (including its Board of Directors, independent legal counsel or
its stockholders) to have made a determination prior to

                                      17.
<PAGE>

the commencement of such action that indemnification of the claimant is proper
in the circumstances because he has met the applicable standard of conduct set
forth in the Delaware General Corporation Law or any other applicable law, nor
an actual determination by the corporation (including its Board of Directors,
independent legal counsel or its stockholders) that the claimant has not met
such applicable standard of conduct, shall be a defense to the action or create
a presumption that claimant has not met the applicable standard of conduct. In
any suit brought by a director or officer to enforce a right to indemnification
or to an advancement of expenses hereunder, the burden of proving that the
director or officer is not entitled to be indemnified, or to such advancement of
expenses, under this Article XI or otherwise shall be on the corporation.

          (e)  Non-Exclusivity of Rights. The rights conferred on any person by
this Bylaw shall not be exclusive of any other right which such person may have
or hereafter acquire under any applicable statute, provision of the Certificate
of Incorporation, Bylaws, agreement, vote of stockholders or disinterested
directors or otherwise, both as to action in his official capacity and as to
action in another capacity while holding office. The corporation is specifically
authorized to enter into individual contracts with any or all of its directors,
officers, employees or agents respecting indemnification and advances, to the
fullest extent not prohibited by the Delaware General Corporation Law or any
other applicable law.

          (f)  Survival of Rights. The rights conferred on any person by this
Bylaw shall continue as to a person who has ceased to be a director, officer,
employee or other agent and shall inure to the benefit of the heirs, executors
and administrators of such a person.

          (g)  Insurance. To the fullest extent permitted by the Delaware
General Corporation Law, the corporation or any other applicable law, upon
approval by the Board of Directors, may purchase insurance on behalf of any
person required or permitted to be indemnified pursuant to this Bylaw.

          (h)  Amendments. Any repeal or modification of this Bylaw shall only
be prospective and shall not affect the rights under this Bylaw in effect at the
time of the alleged occurrence of any action or omission to act that is the
cause of any proceeding against any agent of the corporation.

          (i)  Saving Clause.  If this Bylaw or any portion hereof shall be
invalidated on any ground by any court of competent jurisdiction, then the
corporation shall nevertheless indemnify each director and officer to the full
extent not prohibited by any applicable portion of this Bylaw that shall not
have been invalidated, or by any other applicable law.  If this Section 43 shall
be invalid due to the application of the indemnification provisions of another
jurisdiction, then the corporation shall indemnify each director and officer to
the full extent under applicable law.

          (j)  Certain Definitions. For the purposes of this Bylaw, the
following definitions shall apply:

               (1)  The term "proceeding" shall be broadly construed and shall
include, without limitation, the investigation, preparation, prosecution,
defense, settlement,

                                      18.
<PAGE>

arbitration and appeal of, and the giving of testimony in, any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative.

          (2)  The term "expenses" shall be broadly construed and shall include,
without limitation, court costs, attorneys' fees, witness fees, fines, amounts
paid in settlement or judgment and any other costs and expenses of any nature or
kind incurred in connection with any proceeding.

          (3)  The term the "corporation" shall include, in addition to the
resulting corporation, any constituent corporation (including any constituent of
a constituent) absorbed in a consolidation or merger which, if its separate
existence had continued, would have had power and authority to indemnify its
directors, officers, and employees or agents, so that any person who is or was a
director, officer, employee or agent of such constituent corporation, or is or
was serving at the request of such constituent corporation as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, shall stand in the same position under the provisions
of this Bylaw with respect to the resulting or surviving corporation as he would
have with respect to such constituent corporation if its separate existence had
continued.

          (4)  References to a "director," "executive officer," "officer,"
"employee," or "agent" of the corporation shall include, without limitation,
situations where such person is serving at the request of the corporation as,
respectively, a director, executive officer, officer, employee, trustee or agent
of another corporation, partnership, joint venture, trust or other enterprise.

          (5)  References to "other enterprises" shall include employee benefit
plans; references to "fines" shall include any excise taxes assessed on a person
with respect to an employee benefit plan; and references to "serving at the
request of the corporation" shall include any service as a director, officer,
employee or agent of the corporation which imposes duties on, or involves
services by, such director, officer, employee, or agent with respect to an
employee benefit plan, its participants, or beneficiaries; and a person who
acted in good faith and in a manner he reasonably believed to be in the interest
of the participants and beneficiaries of an employee benefit plan shall be
deemed to have acted in a manner "not opposed to the best interests of the
corporation" as referred to in this Bylaw.

                                  ARTICLE XII

                                    Notices

     Section 44.  Notices.

          (a)  Notice to Stockholders.  Whenever, under any provisions of these
Bylaws, notice is required to be given to any stockholder, it shall be given in
writing, timely and duly deposited in the United States mail, postage prepaid,
and addressed to his last known post office address as shown by the stock record
of the corporation or its transfer agent.

          (b)  Notice to Directors. Any notice required to be given to any
director may be given by the method stated in subsection (a), or by overnight
delivery service, facsimile, telex

                                      19.
<PAGE>

or telegram, except that such notice other than one which is delivered
personally shall be sent to such address as such director shall have filed in
writing with the Secretary, or, in the absence of such filing, to the last known
post office address of such director.

          (c)  Affidavit of Mailing. An affidavit of mailing, executed by a duly
authorized and competent employee of the corporation or its transfer agent
appointed with respect to the class of stock affected, specifying the name and
address or the names and addresses of the stockholder or stockholders, or
director or directors, to whom any such notice or notices was or were given, and
the time and method of giving the same, shall in the absence of fraud, be prima
facie evidence of the facts therein contained.

          (d)  Time Notices Deemed Given. All notices given by mail or by
overnight delivery service, as above provided, shall be deemed to have been
given as at the time of mailing, and all notices given by facsimile, telex or
telegram shall be deemed to have been given as of the sending time recorded at
time of transmission.

          (e)  Methods of Notice. It shall not be necessary that the same method
of giving notice be employed in respect of all directors, but one permissible
method may be employed in respect of any one or more, and any other permissible
method or methods may be employed in respect of any other or others.

          (f)  Failure to Receive Notice. The period or limitation of time
within which any stockholder may exercise any option or right, or enjoy any
privilege or benefit, or be required to act, or within which any director may
exercise any power or right, or enjoy any privilege, pursuant to any notice sent
him in the manner above provided, shall not be affected or extended in any
manner by the failure of such stockholder or such director to receive such
notice.

          (g)  Notice to Person with Whom Communication Is Unlawful. Whenever
notice is required to be given, under any provision of law or of the Certificate
of Incorporation or Bylaws of the corporation, to any person with whom
communication is unlawful, the giving of such notice to such person shall not be
required and there shall be no duty to apply to any governmental authority or
agency for a license or permit to give such notice to such person. Any action or
meeting which shall be taken or held without notice to any such person with whom
communication is unlawful shall have the same force and effect as if such notice
had been duly given. In the event that the action taken by the corporation is
such as to require the filing of a certificate under any provision of the
Delaware General Corporation Law, the certificate shall state, if such is the
fact and if notice is required, that notice was given to all persons entitled to
receive notice except such persons with whom communication is unlawful.

          (h)  Notice to Person with Undeliverable Address.  Whenever notice is
required to be given, under any provision of law or the Certificate of
Incorporation or Bylaws of the corporation, to any stockholder to whom (i)
notice of two consecutive annual meetings, and all notices of meetings or of the
taking of action by written consent without a meeting to such person during the
period between such two consecutive annual meetings, or (ii) all, and at least
two, payments (if sent by first class mail) of dividends or interest on
securities during a twelve-month period, have been mailed addressed to such
person at his address as shown on the records of the corporation and have been
returned undeliverable, the giving of such notice to such person

                                      20.
<PAGE>

shall not be required. Any action or meeting which shall be taken or held
without notice to such person shall have the same force and effect as if such
notice had been duly given. If any such person shall deliver to the corporation
a written notice setting forth his then current address, the requirement that
notice be given to such person shall be reinstated. In the event that the action
taken by the corporation is such as to require the filing of a certificate under
any provision of the Delaware General Corporation Law, the certificate need not
state that notice was not given to persons to whom notice was not required to be
given pursuant to this paragraph.

                                 ARTICLE XIII

                                  Amendments

     Section 45.  Amendments.  Subject to paragraph (h) of Section 43 of the
Bylaws, these Bylaws may be amended or repealed and new Bylaws adopted by the
stockholders entitled to vote.  The Board of Directors shall also have the
power, if such power is conferred upon the Board of Directors by the Certificate
of Incorporation, to adopt, amend, or repeal Bylaws (including, without
limitation, the amendment of any Bylaw setting forth the number of Directors who
shall constitute the whole Board of Directors).

                                  ARTICLE XIV

                            Right Of First Refusal

     Section 46.  Right of First Refusal.  No stockholder shall sell, assign,
pledge, or in any manner transfer any of the shares of stock, of the corporation
or any right or interest therein, whether voluntarily or by operation of law, or
by gift or otherwise, except by a transfer which meets the requirements
hereinafter set forth in this bylaw:

          (a)  If the stockholder desires to sell or otherwise transfer any of
his shares of stock, then the stockholder shall first give written notice
thereof to the corporation. The notice shall name the proposed transferee and
state the number of shares to be transferred, the proposed consideration, and
all other terms and conditions of the proposed transfer.

          (b)  For thirty (30) days following receipt of such notice, the
corporation shall have the option to purchase all (but not less than all) of the
shares specified in the notice at the price and upon the terms set forth in such
notice; provided, however, that, with the consent of the stockholder, the
corporation shall have the option to purchase a lesser portion of the shares
specified in said notice at the price and upon the terms set forth therein. In
the event of a gift, property settlement or other transfer in which the proposed
transferee is not paying the full price for the shares, and that is not
otherwise exempted from the provisions of this Section 46, the price shall be
deemed to be the fair market value of the stock at such time as determined in
good faith by the Board of Directors. In the event the corporation elects to
purchase all of the shares or, with consent of the stockholder, a lesser portion
of the shares, it shall give written notice to the transferring stockholder of
its election and settlement for said shares shall be made as provided below in
paragraph (d).

          (c)  The corporation may assign its rights hereunder.

                                      21.
<PAGE>

          (d)  In the event the corporation and/or its assignee(s) elect to
acquire any of the shares of the transferring stockholder as specified in said
transferring stockholder's notice, the Secretary of the corporation shall so
notify the transferring stockholder and settlement thereof shall be made in cash
within thirty (30) days after the Secretary of the corporation receives said
transferring stockholder's notice; provided that if the terms of payment set
forth in said transferring stockholder's notice were other than cash against
delivery, the corporation and/or its assignee(s) shall pay for said shares on
the same terms and conditions set forth in said transferring stockholder's
notice.

          (e)  In the event the corporation and/or its assignees(s) do not elect
to acquire all of the shares specified in the transferring stockholder's notice,
said transferring stockholder may, within the sixty-day period following the
expiration of the option rights granted to the corporation and/or its
assignees(s) herein, transfer the shares specified in said transferring
stockholder's notice which were not acquired by the corporation and/or its
assignees(s) as specified in said transferring stockholder's notice. All shares
so sold by said transferring stockholder shall continue to be subject to the
provisions of this bylaw in the same manner as before said transfer.

          (f)  Anything to the contrary contained herein notwithstanding, the
following transactions shall be exempt from the provisions of this bylaw:

               (1)  A stockholder's transfer of any or all shares held either
during such stockholder's lifetime or on death by will or intestacy to such
stockholder's immediate family or to any custodian or trustee for the account of
such stockholder or such stockholder's immediate family or to any limited
partnership of which the shareholder, members of such shareholder's immediate
family or any trust for the account of such shareholder or such shareholder's
immediate family will be the general of limited partner(s) of such partnership.
"Immediate family" as used herein shall mean spouse, lineal descendant, father,
mother, brother, or sister of the stockholder making such transfer.

               (2)  A stockholder's bona fide pledge or mortgage of any shares
with a commercial lending institution, provided that any subsequent transfer of
said shares by said institution shall be conducted in the manner set forth in
this bylaw.

               (3)  A stockholder's transfer of any or all of such stockholder's
shares to the corporation or to any other stockholder of the corporation.

               (4)  A stockholder's transfer of any or all of such stockholder's
shares to a person who, at the time of such transfer, is an officer or director
of the corporation.

               (5)  A corporate stockholder's transfer of any or all of its
shares pursuant to and in accordance with the terms of any merger,
consolidation, reclassification of shares or capital reorganization of the
corporate stockholder, or pursuant to a sale of all or substantially all of the
stock or assets of a corporate stockholder.

               (6)  A corporate stockholder's transfer of any or all of its
shares to any or all of its stockholders.

                                      22.
<PAGE>

               (7)  A transfer by a stockholder which is a limited or general
partnership to any or all of its partners or former partners.

               (8)  A transfer by a stockholder to a person or entity who
controls, is controlled by or under common control with such stockholder.

     In any such case, the transferee, assignee, or other recipient shall
receive and hold such stock subject to the provisions of this bylaw, and there
shall be no further transfer of such stock except in accord with this bylaw.

          (g)  The provisions of this bylaw may be waived with respect to any
transfer either by the corporation, upon duly authorized action of its Board of
Directors, or by the stockholders, upon the express written consent of the
owners of a majority of the voting power of the corporation (excluding the votes
represented by those shares to be transferred by the transferring stockholder).
This bylaw may be amended or repealed either by a duly authorized action of the
Board of Directors or by the stockholders, upon the express written consent of
the owners of a majority of the voting power of the corporation.

          (h)  Any sale or transfer, or purported sale or transfer, of
securities of the corporation shall be null and void unless the terms,
conditions, and provisions of this bylaw are strictly observed and followed.

          (i)  The foregoing right of first refusal shall terminate on either of
the following dates, whichever shall first occur:

               (1)  On September 23, 2008; or

               (2)  Upon the date securities of the corporation are first
offered to the public pursuant to a registration statement filed with, and
declared effective by, the United States Securities and Exchange Commission
under the Securities Act of 1933, as amended.

          (j)  The certificates representing shares of stock of the corporation
shall bear on their face the following legend so long as the foregoing right of
first refusal remains in effect:

          "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A
          RIGHT OF FIRST REFUSAL OPTION IN FAVOR OF THE CORPORATION
          AND/OR ITS ASSIGNEE(S), AS PROVIDED IN THE BYLAWS OF THE
          CORPORATION."

                                  ARTICLE XIV

                               Loans To Officers

     Section 47.  Loans to Officers.  The corporation may lend money to, or
guarantee any obligation of, or otherwise assist any officer or other employee
of the corporation or of its subsidiaries, including any officer or employee who
is a Director of the corporation or its subsidiaries, whenever, in the judgment
of the Board of Directors, such loan, guarantee or assistance may reasonably be
expected to benefit the corporation.  The loan, guarantee or other assistance
may be with or without interest and may be unsecured, or secured in such manner
as the Board of Directors shall approve, including, without limitation, a pledge
of shares of stock of

                                      23.

the corporation. Nothing in these Bylaws shall be deemed to deny, limit or
restrict the powers of guaranty or warranty of the corporation at common law or
under any statute.

determine or the business of the corporation may require.

                            STOCKHOLDERS' MEETINGS

     Section 4.   Place Of Meetings.  Meetings of the stockholders of the
corporation shall be held at such place, either within or without the State of
Delaware, as may be designated from time to time by the Board of Directors, or,
if not so designated, then at the office of the corporation required to be

     Section 5.   Annual Meetings.

          (a)  The annual meeting of the stockholders of the corporation, for
the purpose of election of directors and for such other business as may lawfully
come before it, shall be held on such date and at such time as may be designated
from time to time by the Board of Directors. Nominations of persons for election
to the Board of Directors of the corporation and the proposal of business to be
considered by the stockholders may be made at an annual meeting of stockholders:
(i) pursuant to the corporation's notice of meeting of stockholders; (ii) by or
at the direction of the Board of Directors; or (iii) by any stockholder of the
corporation who was a

                                      1.
<PAGE>

stockholder of record at the time of giving of notice provided for in the
following paragraph, who is entitled to vote at the meeting and who complied
with the notice procedures set forth in Section 5.

          (b)  At an annual meeting of the stockholders, only such business
shall be conducted as shall have been properly brought before the meeting. For
nominations or other business to be properly brought before an annual meeting by
a stockholder pursuant to clause (c) of Section 5(a) of these Bylaws, (i) the
stockholder must have given timely notice thereof in writing to the Secretary of
the corporation, (ii) such other business must be a proper matter for
stockholder action under the Delaware General Corporation Law ("DGCL"), (iii) if
the stockholder, or the beneficial owner on whose behalf any such proposal or
nomination is made, has provided the corporation with a Solicitation Notice (as
defined in this Section 5(b)), such stockholder or beneficial owner must, in the
case of a proposal, have delivered a proxy statement and form of proxy to
holders of at least the percentage of the corporation's voting shares required
under applicable law to carry any such proposal, or, in the case of a nomination
or nominations, have delivered a proxy statement and form of proxy to holders of
a percentage of the corporation's voting shares reasonably believed by such
stockholder or beneficial owner to be sufficient to elect the nominee or
nominees proposed to be nominated by such stockholder, and must, in either case,
have included in such materials the Solicitation Notice, and (iv) if no
Solicitation Notice relating thereto has been timely provided pursuant to this
section, the stockholder or beneficial owner proposing such business or
nomination must not have solicited a number of proxies sufficient to have
required the delivery of such a Solicitation Notice under this Section 5. To be
timely, a stockholder's notice shall be delivered to the Secretary at the
principal executive offices of the Corporation not later than the close of
business on the ninetieth (90th) day nor earlier than the close of business on
the one hundred twentieth (120th) day prior to the first anniversary of the
preceding year's annual meeting; provided, however, that in the event that the
date of the annual meeting is advanced more than thirty (30) days prior to or
delayed by more than thirty (30) days after the anniversary of the preceding
year's annual meeting, notice by the stockholder to be timely must be so
delivered not earlier than the close of business on the one hundred twentieth
(120th) day prior to such annual meeting and not later than the close of
business on the later of the ninetieth (90th) day prior to such annual meeting
or the tenth (10th) day following the day on which public announcement of the
date of such meeting is first made. In no event shall the public announcement of
an adjournment of an annual meeting commence a new time period for the giving of
a stockholder's notice as described above. Such stockholder's notice shall set
forth: (A) as to each person whom the stockholder proposed to nominate for
election or reelection as a director all information relating to such person
that is required to be disclosed in solicitations of proxies for election of
directors in an election contest, or is otherwise required, in each case
pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended
(the "1934 Act") and Rule 14a-11 thereunder (including such person's written
consent to being named in the proxy statement as a nominee and to serving as a
director if elected); (B) as to any other business that the stockholder proposes
to bring before the meeting, a brief description of the business desired to be
brought before the meeting, the reasons for conducting such business at the
meeting and any material interest in such business of such stockholder and the
beneficial owner, if any, on whose behalf the proposal is made; and (C) as to
the stockholder giving the notice and the beneficial owner, if any, on whose
behalf the nomination or proposal is made (i) the name and address of such
stockholder, as they appear on the corporation's books, and of such beneficial
owner, (ii) the class and number of shares of the corporation which are

                                      2.
<PAGE>

owned beneficially and of record by such stockholder and such beneficial owner,
and (iii) whether either such stockholder or beneficial owner intends to deliver
a proxy statement and form of proxy to holders of, in the case of the proposal,
at least the percentage of the corporation's voting shares required under
applicable law to carry the proposal or, in the case of a nomination or
nominations, a sufficient number of holders of the corporation's voting shares
to elect such nominee or nominees (an affirmative statement of such intent, a
"Solicitation Notice").

          (c)  Notwithstanding anything in the second sentence of Section 5(b)
of these Bylaws to the contrary, in the event that the number of directors to be
elected to the Board of Directors of the Corporation is increased and there is
no public announcement naming all of the nominees for director or specifying the
size of the increased Board of Directors made by the corporation at least one
hundred (100) days prior to the first anniversary of the preceding year's annual
meeting, a stockholder's notice required by this Section 5 shall also be
considered timely, but only with respect to nominees for any new positions
created by such increase, if it shall be delivered to the Secretary at the
principal executive offices of the corporation not later than the close of
business on the tenth (10th) day following the day on which such public
announcement is first made by the corporation.

          (d)  Only such persons who are nominated in accordance with the
procedures set forth in this Section 5 shall be eligible to serve as directors
and only such business shall be conducted at a meeting of stockholders as shall
have been brought before the meeting in accordance with the procedures set forth
in this Section 5. Except as otherwise provided by law, the Chairman of the
meeting shall have the power and duty to determine whether a nomination or any
business proposed to be brought before the meeting was made, or proposed, as the
case may be, in accordance with the procedures set forth in these Bylaws and, if
any proposed nomination or business is not in compliance with these Bylaws, to
declare that such defective proposal or nomination shall not be presented for
stockholder action at the meeting and shall be disregarded.

          (e)  Notwithstanding the foregoing provisions of this Section 5, in
order to include information with respect to a stockholder proposal in the proxy
statement and form of proxy for a stockholders' meeting, stockholders must
provide notice as required by the regulations promulgated under the 1934 Act.
Nothing in these Bylaws shall be deemed to affect any rights of stockholders to
request inclusion of proposals in the corporation proxy statement pursuant to
Rule 14a-8 under the 1934 Act.

          (f)  For purposes of this Section 5, "public announcement" shall mean
disclosure in a press release reported by the Dow Jones News Service, Associated
Press or comparable national news service or in a document publicly filed by the
corporation with the Securities and Exchange Commission pursuant to Section 13,
14 or 15(d) of the 1934 Act.

     Section 6.   Special Meetings.

          (a)  Special meetings of the stockholders of the corporation may be
called, for any purpose or purposes, by (i) the Chairman of the Board of
Directors, (ii) the Chief Executive Officer, or (iii) the Board of Directors
pursuant to a resolution adopted by a majority of the total

                                      3.
<PAGE>

number of authorized directors (whether or not there exist any vacancies in
previously authorized directorships at the time any such resolution is presented
to the Board of Directors for adoption).

          (b)  If a special meeting is properly called by any person or persons
other than the Board of Directors, the request shall be in writing, specifying
the general nature of the business proposed to be transacted, and shall be
delivered personally or sent by registered mail or by telegraphic or other
facsimile transmission to the Chairman of the Board of Directors, the Chief
Executive Officer, or the Secretary of the corporation. No business may be
transacted at such special meeting otherwise than specified in such notice. The
Board of Directors shall determine the time and place of such special meeting,
which shall be held not less than thirty-five (35) nor more than one hundred
twenty (120) days after the date of the receipt of the request. Upon
determination of the time and place of the meeting, the officer receiving the
request shall cause notice to be given to the stockholders entitled to vote, in
accordance with the provisions of Section 7 of these Bylaws. If the notice is
not given within one hundred (100) days after the receipt of the request, the
person or persons properly requesting the meeting may set the time and place of
the meeting and give the notice. Nothing contained in this paragraph (b) shall
be construed as limiting, fixing, or affecting the time when a meeting of
stockholders called by action of the Board of Directors may be held.

          (c)  Nominations of persons for election to the Board of Directors may
be made at a special meeting of stockholders at which directors are to be
elected pursuant to the corporation's notice of meeting (i) by or at the
direction of the Board of Directors or (ii) by any stockholder of the
corporation who is a stockholder of record at the time of giving notice provided
for in these Bylaws who shall be entitled to vote at the meeting and who
complies with the notice procedures set forth in this Section 6(c). In the event
the corporation calls a special meeting of stockholders for the purpose of
electing one or more directors to the Board of Directors, any such stockholder
may nominate a person or persons (as the case may be), for election to such
position(s) as specified in the corporation's notice of meeting, if the
stockholder's notice required by Section 5(b) of these Bylaws shall be delivered
to the Secretary at the principal executive offices of the corporation not
earlier than the close of business on the one hundred twentieth (120th) day
prior to such special meeting and not later than the close of business on the
later of the ninetieth (90th) day prior to such meeting or the tenth (10th) day
following the day on which public announcement is first made of the date of the
special meeting and of the nominees proposed by the Board of Directors to be
elected at such meeting. In no event shall the public announcement of an
adjournment of a special meeting commence a new time period for the giving of a
stockholder's notice as described above.

     Section 7.   Notice Of Meetings. Except as otherwise provided by law or the
Certificate of Incorporation, written notice of each meeting of stockholders
shall be given not less than ten (10) nor more than sixty (60) days before the
date of the meeting to each stockholder entitled to vote at such meeting, such
notice to specify the place, date and hour and purpose or purposes of the
meeting. Notice of the time, place and purpose of any meeting of stockholders
may be waived in writing, signed by the person entitled to notice thereof,
either before or after such meeting, and will be waived by any stockholder by
his attendance thereat in person or by proxy, except when the stockholder
attends a meeting for the express purpose of objecting, at the beginning of the
meeting, to the transaction of any business because the meeting is not lawfully
called or convened. Any stockholder so waiving notice of such meeting shall be

                                      4.
<PAGE>

bound by the proceedings of any such meeting in all respects as if due notice
thereof had been given.

     Section 8.   Quorum. At all meetings of stockholders, except where
otherwise provided by statute or by the Certificate of Incorporation, or by
these Bylaws, the presence, in person or by proxy duly authorized, of the
holders of a majority of the outstanding shares of stock entitled to vote shall
constitute a quorum for the transaction of business. In the absence of a quorum,
any meeting of stockholders may be adjourned, from time to time, either by the
chairman of the meeting or by vote of the holders of a majority of the shares
represented thereat, but no other business shall be transacted at such meeting.
The stockholders present at a duly called or convened meeting, at which a quorum
is present, may continue to transact business until adjournment, notwithstanding
the withdrawal of enough stockholders to leave less than a quorum. Except as
otherwise provided by statute, the Certificate of Incorporation or these Bylaws,
in all matters other than the election of directors, the affirmative vote of the
majority of shares present in person or represented by proxy at the meeting and
entitled to vote on the subject matter shall be the act of the stockholders.
Except as otherwise provided by statute, the Certificate of Incorporation or
these Bylaws, directors shall be elected by a plurality of the votes of the
shares present in person or represented by proxy at the meeting and entitled to
vote on the election of directors. Where a separate vote by a class or classes
or series is required, except where otherwise provided by the statute or by the
Certificate of Incorporation or these Bylaws, a majority of the outstanding
shares of such class or classes or series, present in person or represented by
proxy, shall constitute a quorum entitled to take action with respect to that
vote on that matter and, except where otherwise provided by the statute or by
the Certificate of Incorporation or these Bylaws, the affirmative vote of the
majority (plurality, in the case of the election of directors) of the votes cast
by the holders of shares of such class or classes or series shall be the act of
such class or classes or series.

     Section 9.   Adjournment And Notice Of Adjourned Meetings.  Any meeting of
stockholders, whether annual or special, may be adjourned from time to time
either by the chairman of the meeting or by the vote of a majority of the shares
casting votes.  When a meeting is adjourned to another time or place, notice
need not be given of the adjourned meeting if the time and place thereof are
announced at the meeting at which the adjournment is taken.  At the adjourned
meeting, the corporation may transact any business which might have been
transacted at the original meeting.  If the adjournment is for more than thirty
(30) days or if after the adjournment a new record date is fixed for the
adjourned meeting, a notice of the adjourned meeting shall be given to each
stockholder of record entitled to vote at the meeting.

     Section 10.  Voting Rights. For the purpose of determining those
stockholders entitled to vote at any meeting of the stockholders, except as
otherwise provided by law, only persons in whose names shares stand on the stock
records of the corporation on the record date, as provided in Section 12 of
these Bylaws, shall be entitled to vote at any meeting of stockholders. Every
person entitled to vote shall have the right to do so either in person or by an
agent or agents authorized by a proxy granted in accordance with Delaware law.
An agent so appointed need not be a stockholder. No proxy shall be voted after
three (3) years from its date of creation unless the proxy provides for a longer
period.

                                      5.
<PAGE>

     Section 11.  Joint Owners Of Stock.  If shares or other securities having
voting power stand of record in the names of two (2) or more persons, whether
fiduciaries, members of a partnership, joint tenants, tenants in common, tenants
by the entirety, or otherwise, or if two (2) or more persons have the same
fiduciary relationship respecting the same shares, unless the Secretary is given
written notice to the contrary and is furnished with a copy of the instrument or
order appointing them or creating the relationship wherein it is so provided,
their acts with respect to voting shall have the following effect:  (a) if only
one (1) votes, his act binds all; (b) if more than one (1) votes, the act of the
majority so voting binds all; (c) if more than one (1) votes, but the vote is
evenly split on any particular matter, each faction may vote the securities in
question proportionally, or may apply to the Delaware Court of Chancery for
relief as provided in the DGCL, Section 217(b).  If the instrument filed with
the Secretary shows that any such tenancy is held in unequal interests, a
majority or even-split for the purpose of subsection (c) shall be a majority or
even-split in interest.

     Section 12.  List Of Stockholders. The Secretary shall prepare and make, at
least ten (10) days before every meeting of stockholders, a complete list of the
stockholders entitled to vote at said meeting, arranged in alphabetical order,
showing the address of each stockholder and the number of shares registered in
the name of each stockholder. Such list shall be open to the examination of any
stockholder, for any purpose germane to the meeting, during ordinary business
hours, for a period of at least ten (10) days prior to the meeting, either at a
place within the city where the meeting is to be held, which place shall be
specified in the notice of the meeting, or, if not specified, at the place where
the meeting is to be held. The list shall be produced and kept at the time and
place of meeting during the whole time thereof and may be inspected by any
stockholder who is present.

     Section 13.  Action Without Meeting.

          (a)  No action shall be taken by the stockholders except at an annual
or special meeting of stockholders called in accordance with these Bylaws, and
no action shall be taken by the stockholders by written consent.

     Section 14.  Organization.

          (a)  At every meeting of stockholders, the Chairman of the Board of
Directors, or, if a Chairman has not been appointed or is absent, the President,
or, if the President is absent, a chairman of the meeting chosen by a majority
in interest of the stockholders entitled to vote, present in person or by proxy,
shall act as chairman.  The Secretary, or, in his absence, an Assistant
Secretary directed to do so by the President, shall act as secretary of the
meeting.

          (b)  The Board of Directors of the corporation shall be entitled to
make such rules or regulations for the conduct of meetings of stockholders as it
shall deem necessary, appropriate or convenient. Subject to such rules and
regulations of the Board of Directors, if any, the chairman of the meeting shall
have the right and authority to prescribe such rules, regulations and procedures
and to do all such acts as, in the judgment of such chairman, are necessary,
appropriate or convenient for the proper conduct of the meeting, including,
without limitation, establishing an agenda or order of business for the meeting,
rules and procedures for maintaining order at the meeting and the safety of
those present, limitations on participation in

                                      6.
<PAGE>

such meeting to stockholders of record of the corporation and their duly
authorized and constituted proxies and such other persons as the chairman shall
permit, restrictions on entry to the meeting after the time fixed for the
commencement thereof, limitations on the time allotted to questions or comments
by participants and regulation of the opening and closing of the polls for
balloting on matters which are to be voted on by ballot. Unless and to the
extent determined by the Board of Directors or the chairman of the meeting,
meetings of stockholders shall not be required to be held in accordance with

                                   DIRECTORS

     Section 15.  Number And Term Of Office. The authorized number of directors
of the corporation shall be fixed in accordance with the Certificate of
Incorporation. Directors need not be stockholders unless so required by the
Certificate of Incorporation. If for any cause, the directors shall not have
been elected at an annual meeting, they may be elected as soon thereafter as
convenient at a special meeting of the stockholders called for that purpose in
the manner provided in these Bylaws.

     Section 16.  Powers.  The powers of the corporation shall be exercised, its
business conducted and its property controlled by the Board of Directors, except
as may be otherwise provided by statute or by the Certificate of Incorporation.

     Section 17.  Classes of Directors.  Subject to the rights of the holders of
any series of Preferred Stock to elect additional directors under specified
circumstances, the directors shall be divided into three classes designated as
Class I, Class II and Class III, respectively.  Directors shall be assigned to
each class in accordance with a resolution or resolutions adopted by the Board
of Directors.  At the first annual meeting of stockholders following the
adoption and filing of the Certificate of Incorporation providing for a
classified Board of Directors, the term of office of the Class I directors shall
expire and Class I directors shall be elected for a full term of three years.
At the second annual meeting of stockholders following the adoption and filing
of the Certificate of Incorporation providing for a classified Board of
Directors, the term of office of the Class II directors shall expire and Class
II directors shall be elected for a full term of three years.  At the third
annual meeting of stockholders following the adoption and filing of the
Certificate of Incorporation providing for a classified Board of Directors, the
term of office of the Class III directors shall expire and Class III directors
shall be elected for a full term of three years.  At each succeeding annual
meeting of stockholders, directors shall be elected for a full term of three
years to succeed the directors of the class whose terms expire at such annual
meeting.

     Notwithstanding the foregoing provisions of this section, each director
shall serve until his successor is duly elected and qualified or until his
death, resignation or removal.  No decrease in the number of directors
constituting the Board of Directors shall shorten the term of any incumbent
director.

     Section 18.  Vacancies.

          (a)  Unless otherwise provided in the Certificate of Incorporation,
any vacancies on the Board of Directors resulting from death, resignation,
disqualification, removal or other causes and any newly created directorships
resulting from any increase in the number of directors shall, unless the Board
of Directors determines by resolution that any such vacancies or newly created
directorships shall be filled by stockholders, be filled only by the affirmative
vote of a majority of the directors then in office, even though less than a
quorum of the Board of Directors. Any director elected in accordance with the
preceding sentence shall hold office for the remainder of the full term of the
director for which the vacancy was created or occurred and until such director's
successor shall have been elected and qualified. A vacancy in the Board of
Directors shall be deemed to exist under this Section 18 in the case of the
death, removal or resignation of any director. (Del. Code Ann., tit. 8,
Section 223(a), (b))

          (b)  If at the time of filling any vacancy or any newly created
directorship, the directors then in office shall constitute less than a majority
of the whole board (as constituted immediately prior to any such increase), the
Delaware Court of Chancery may, upon application of any stockholder or
stockholders holding at least ten percent (10%) of the total number of the
shares at the time outstanding having the right to vote for such directors,
summarily order an election to be held to fill any such vacancies or newly
created directorships, or to replace the directors chosen by the directors then
in offices as aforesaid, which election shall be governed by Section 211 of the
DGCL. (Del. Code Ann., tit. 8, Section 223(c)).

     Section 19.  Resignation. Any director may resign at any time by delivering
his written resignation to the Secretary, such resignation to specify whether it
will be effective at a particular time, upon receipt by the Secretary or at the
pleasure of the Board of Directors. If no such specification is made, it shall
be deemed effective at the pleasure of the Board of Directors. When one or more
directors shall resign from the Board of Directors, effective at a future date,
a majority of the directors then in office, including those who have so
resigned, shall have power to fill such vacancy or vacancies, the vote thereon
to take effect when such resignation or resignations shall become effective, and
each Director so chosen shall hold office for the unexpired portion of the term
of the Director whose place shall be vacated and until his successor shall have
been duly elected and qualified. (Del. Code Ann., tit. 8, Sections 141(b),
223(d))

     Section 20.  Removal.

                  (a)  Neither the Board of Directors nor any individual
director may be removed without cause.

                  (b)  Subject to any limitation imposed by law, any individual
director or directors may be removed with cause by the affirmative vote of a
majority of the voting power of the corporation entitled to vote at an election
of directors.

notice. All such waivers shall be filed with the corporate records or made a
part of the minutes of the meeting. (Del. Code Ann., tit. 8, Section 229)

     Section 24.  Fees And Compensation.  Directors shall be entitled to such
compensation for their services as may be approved by the Board of Directors,
including, if so approved, by resolution of the Board of Directors, a fixed sum
and expenses of attendance, if any, for attendance at each regular or special
meeting of the Board of Directors and at any meeting of a committee of the Board
of Directors.  Nothing herein contained shall be construed to preclude any
director from serving the corporation in any other capacity as an officer,
agent, employee, or otherwise and receiving compensation therefor.  (Del. Code
Ann., tit. 8, Section 141(h))

     Section 25.  Committees.

member. (Del. Code Ann., tit. 8, Section 141(c))

determined by the Board of Directors, or by any such committee, and when notice
thereof has been given to each member of such committee, no further notice of
such regular meetings need be given thereafter.  Special meetings of any such
committee may be held at any place which has been determined from time to time
by such committee, and may be called by any director who is a member of such
committee, upon written notice to the members of such committee of the time and
place of such special meeting given in the manner provided for the giving of
written notice to members of the Board of Directors of the time and place of
special meetings of the Board of Directors.  Notice of any special meeting of

meeting is not lawfully called or convened.  A majority of the authorized number
of members of any such committee shall constitute a quorum for the transaction
of business, and the act of a majority of those present at any meeting at which
a quorum is present shall be the act of such committee.  (Del. Code Ann., tit.

record date shall not precede the date upon which the resolution fixing the
record date is adopted, and which record date shall be not more than sixty (60)
days prior to such action. If no record date is fixed, the record date for
determining stockholders for any such purpose shall be at the close of business
on the day on which the Board of Directors adopts the resolution relating
thereto. (Del. Code Ann., tit. 8, Section 213)

     Section 38.  Registered Stockholders.  The corporation shall be entitled to
recognize the exclusive right of a person registered on its books as the owner
of shares to receive dividends, and to vote as such owner, and shall not be
bound to recognize any equitable or other claim to or interest in such share or
shares on the part of any other person whether or not it shall have express or
other notice thereof, except as otherwise provided by the laws of Delaware.

                      OTHER SECURITIES OF THE CORPORATION

     Section 39.  Execution Of Other Securities.  All bonds, debentures and
other corporate securities of the corporation, other than stock certificates
(covered in Section 34), may be signed by the Chairman of the Board of
Directors, the President or any Vice President, or such other person as may be
authorized by the Board of Directors, and the corporate seal impressed thereon
or a facsimile of such seal imprinted thereon and attested by the signature of
the Secretary or an Assistant Secretary, or the Chief Financial Officer or
Treasurer or an Assistant Treasurer; provided, however, that where any such
bond, debenture or other corporate security shall be authenticated by the manual
signature, or where permissible facsimile signature, of a trustee under an
indenture pursuant to which such bond, debenture or other corporate security
shall be issued, the signatures of the persons signing and attesting the
corporate seal on such bond, debenture or other corporate security may be the
imprinted facsimile of the signatures of such persons. Interest coupons
appertaining to any such bond, debenture or other corporate security,
authenticated by a trustee as aforesaid, shall be signed by the Treasurer or an
Assistant Treasurer of the corporation or such other person as may be authorized
by the Board of Directors, or bear imprinted thereon the facsimile signature of
such person. In case any officer who shall have signed or attested any bond,
debenture or other corporate security, or whose facsimile signature shall appear
thereon or on any such interest coupon, shall have ceased to be such officer
before the bond, debenture or other corporate security so signed or attested
shall have been delivered, such bond, debenture or other corporate security
nevertheless may be adopted by the corporation and issued and delivered as
though the person who signed the same or whose facsimile signature shall have
been used thereon had not ceased to be such officer of the corporation.

     Section 41.  Dividend Reserve.  Before payment of any dividend, there may
be set aside out of any funds of the corporation available for dividends such
sum or sums as the Board of Directors from time to time, in their absolute
discretion, think proper as a reserve or reserves to meet contingencies, or for
equalizing dividends, or for repairing or maintaining any property of the
corporation, or for such other purpose as the Board of Directors shall think
conducive to the interests of the corporation, and the Board of Directors may
modify or abolish any such reserve in the manner in which it was created. (Del.

                                  ARTICLE XI

                                INDEMNIFICATION

     Section 43.  Indemnification Of Directors, Executive Officers, Other
Officers, Employees And Other Agents.

           (a)    Directors and Officers.  The corporation shall indemnify its
directors and officers to the fullest extent not prohibited by the DGCL or any
other applicable law; provided, however, that the corporation may modify the
extent of such indemnification by individual contracts with its directors and
officers; and, provided, further, that the corporation shall not be required to
indemnify any director or officer in connection with any proceeding (or part
thereof) initiated by such person unless (i) such indemnification is expressly
required to be made by law, (ii) the proceeding was authorized by the Board of
Directors of the corporation, (iii) such indemnification is provided by the
corporation, in its sole discretion, pursuant to the powers vested in the
corporation under the DGCL or any other applicable law or (iv) such
indemnification is required to be made under subsection (d).

           (b)    Employees and Other Agents.  The corporation shall have power
to indemnify its employees and other agents as set forth in the DGCL or any
other applicable law. The Board of Directors shall have the power to delegate
the determination of whether

                                      17.
<PAGE>

indemnification shall be given to any such person or other persons as the Board
of Directors shall determine.

           (c)    Expenses.  The corporation shall advance to any person who was
or is a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative, by reason of the fact that he is or was a director or officer, of
the corporation, or is or was serving at the request of the corporation as a
director or executive officer of another corporation, partnership, joint
venture, trust or other enterprise, prior to the final disposition of the
proceeding, promptly following request therefor, all expenses incurred by any
director or officer in connection with such proceeding upon receipt of an
undertaking by or on behalf of such person to repay said amounts if it should be
determined ultimately that such person is not entitled to be indemnified under
this Section 43 or otherwise.

     Notwithstanding the foregoing, unless otherwise determined pursuant to
paragraph (e) of this Section 43, no advance shall be made by the corporation to
an officer of the corporation (except by reason of the fact that such officer is
or was a director of the corporation in which event this paragraph shall not
apply) in any action, suit or proceeding, whether civil, criminal,
administrative or investigative, if a determination is reasonably and promptly
made (i) by the Board of Directors by a majority vote of a quorum consisting of
directors who were not parties to the proceeding, or (ii) if such quorum is not
obtainable, or, even if obtainable, a quorum of disinterested directors so
directs, by independent legal counsel in a written opinion, that the facts known
to the decision-making party at the time such determination is made demonstrate
clearly and convincingly that such person acted in bad faith or in a manner that
such person did not believe to be in or not opposed to the best interests of the
corporation.

           (d)    Enforcement.  Without the necessity of entering into an
express contract, all rights to indemnification and advances to directors and
officers under this Bylaw shall be deemed to be contractual rights and be
effective to the same extent and as if provided for in a contract between the
corporation and the director or officer. Any right to indemnification or
advances granted by this Section 43 to a director or officer shall be
enforceable by or on behalf of the person holding such right in any court of
competent jurisdiction if (i) the claim for indemnification or advances is
denied, in whole or in part, or (ii) no disposition of such claim is made within
ninety (90) days of request therefor. The claimant in such enforcement action,
if successful in whole or in part, shall be entitled to be paid also the expense
of prosecuting his claim. In connection with any claim for indemnification, the
corporation shall be entitled to raise as a defense to any such action that the
claimant has not met the standards of conduct that make it permissible under the
DGCL or any other applicable law for the corporation to indemnify the claimant
for the amount claimed. In connection with any claim by an officer of the
corporation (except in any action, suit or proceeding, whether civil, criminal,
administrative or investigative, by reason of the fact that such executive
officer is or was a director of the corporation) for advances, the corporation
shall be entitled to raise a defense as to any such action clear and convincing
evidence that such person acted in bad faith or in a manner that such person did
not believe to be in or not opposed to the best interests of the corporation, or
with respect to any criminal action or proceeding that such person acted without
reasonable cause to believe that his conduct was lawful. Neither the failure of
the corporation (including its Board of Directors, independent legal counsel or
its stockholders) to have made a determination prior to the

                                      18.
<PAGE>

commencement of such action that indemnification of the claimant is proper in
the circumstances because he has met the applicable standard of conduct set
forth in the DGCL or any other applicable law, nor an actual determination by
the corporation (including its Board of Directors, independent legal counsel or
its stockholders) that the claimant has not met such applicable standard of
conduct, shall be a defense to the action or create a presumption that claimant
has not met the applicable standard of conduct. In any suit brought by a
director or officer to enforce a right to indemnification or to an advancement
of expenses hereunder, the burden of proving that the director or officer is not
entitled to be indemnified, or to such advancement of expenses, under this
Article XI or otherwise shall be on the corporation.

           (e)    Non-Exclusivity of Rights.  The rights conferred on any person
by this Bylaw shall not be exclusive of any other right which such person may
have or hereafter acquire under any applicable statute, provision of the
Certificate of Incorporation, Bylaws, agreement, vote of stockholders or
disinterested directors or otherwise, both as to action in his official capacity
and as to action in another capacity while holding office. The corporation is
specifically authorized to enter into individual contracts with any or all of
its directors, officers, employees or agents respecting indemnification and
advances, to the fullest extent not prohibited by the Delaware General
Corporation Law, or by any other applicable law.

           (f)    Survival of Rights.  The rights conferred on any person by
this Bylaw shall continue as to a person who has ceased to be a director,
officer, employee or other agent and shall inure to the benefit of the heirs,
executors and administrators of such a person.

           (g)    Insurance.  To the fullest extent permitted by the DGCL or any
other applicable law, the corporation, upon approval by the Board of Directors,
may purchase insurance on behalf of any person required or permitted to be
indemnified pursuant to this Section 43.

           (h)    Amendments.  Any repeal or modification of this Section 43
shall only be prospective and shall not affect the rights under this Bylaw in
effect at the time of the alleged occurrence of any action or omission to act
that is the cause of any proceeding against any agent of the corporation.

           (i)    Saving Clause.  If this Bylaw or any portion hereof shall be
invalidated on any ground by any court of competent jurisdiction, then the
corporation shall nevertheless indemnify each director and officer to the full
extent not prohibited by any applicable portion of this Section 43 that shall
not have been invalidated, or by any other applicable law. If this Section 43
shall be invalid due to the application of the indemnification provisions of
another jurisdiction, then the corporation shall indemnify each director and
officer to the full extent under any other applicable law.

           (j)    Certain Definitions.  For the purposes of this Bylaw, the
following definitions shall apply:

                  (1)  The term "proceeding" shall be broadly construed and
shall include, without limitation, the investigation, preparation, prosecution,
defense, settlement,

                                      19.
<PAGE>

arbitration and appeal of, and the giving of testimony in, any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative.

                  (2)  The term "expenses" shall be broadly construed and shall
include, without limitation, court costs, attorneys' fees, witness fees, fines,
amounts paid in settlement or judgment and any other costs and expenses of any
nature or kind incurred in connection with any proceeding.

                  (3)  The term the "corporation" shall include, in addition to
the resulting corporation, any constituent corporation (including any
constituent of a constituent) absorbed in a consolidation or merger which, if
its separate existence had continued, would have had power and authority to
indemnify its directors, officers, and employees or agents, so that any person
who is or was a director, officer, employee or agent of such constituent
corporation, or is or was serving at the request of such constituent corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, shall stand in the same position under
the provisions of this Section 43 with respect to the resulting or surviving
corporation as he would have with respect to such constituent corporation if its
separate existence had continued.

                  (4)  References to a "director," "executive officer,"
"officer," "employee," or "agent" of the corporation shall include, without
limitation, situations where such person is serving at the request of the
corporation as, respectively, a director, executive officer, officer, employee,
trustee or agent of another corporation, partnership, joint venture, trust or
other enterprise.

                  (5)  References to "other enterprises" shall include employee
benefit plans; references to "fines" shall include any excise taxes assessed on
a person with respect to an employee benefit plan; and references to "serving at
the request of the corporation" shall include any service as a director,
officer, employee or agent of the corporation which imposes duties on, or
involves services by, such director, officer, employee, or agent with respect to
an employee benefit plan, its participants, or beneficiaries; and a person who
acted in good faith and in a manner he reasonably believed to be in the interest
of the participants and beneficiaries of an employee benefit plan shall be
deemed to have acted in a manner "not opposed to the best interests of the
corporation" as referred to in this Section 43.

                                  ARTICLE XII

                                    NOTICES

     Section 44.  Notices.

           (a)    Notice To Stockholders.  Whenever, under any provisions of
these Bylaws, notice is required to be given to any stockholder, it shall be
given in writing, timely and duly deposited in the United States mail, postage
prepaid, and addressed to his last known post office address as shown by the
stock record of the corporation or its transfer agent. (Del. Code Ann., tit. 8,
Section 222)

                                      20.
<PAGE>

           (b)    Notice To Directors.  Any notice required to be given to any
director may be given by the method stated in subsection (a), or by overnight
delivery service, facsimile, telex or telegram, except that such notice other
than one which is delivered personally shall be sent to such address as such
director shall have filed in writing with the Secretary, or, in the absence of
such filing, to the last known post office address of such director.

           (c)    Affidavit Of Mailing.  An affidavit of mailing, executed by a
duly authorized and competent employee of the corporation or its transfer agent
appointed with respect to the class of stock affected, specifying the name and
address or the names and addresses of the stockholder or stockholders, or
director or directors, to whom any such notice or notices was or were given, and
the time and method of giving the same, shall in the absence of fraud, be prima
facie evidence of the facts therein contained. (Del. Code Ann., tit. 8, Section
222)

           (d)    Time Notices Deemed Given.  All notices given by mail or by
overnight delivery service, as above provided, shall be deemed to have been
given as at the time of mailing, and all notices given by facsimile, telex or
telegram shall be deemed to have been given as of the sending time recorded at
time of transmission.

           (e)    Methods of Notice.  It shall not be necessary that the same
method of giving notice be employed in respect of all directors, but one
permissible method may be employed in respect of any one or more, and any other
permissible method or methods may be employed in respect of any other or others.

           (f)    Failure To Receive Notice.  The period or limitation of time
within which any stockholder may exercise any option or right, or enjoy any
privilege or benefit, or be required to act, or within which any director may
exercise any power or right, or enjoy any privilege, pursuant to any notice sent
him in the manner above provided, shall not be affected or extended in any
manner by the failure of such stockholder or such director to receive such
notice.

           (g)    Notice To Person With Whom Communication Is Unlawful.
Whenever notice is required to be given, under any provision of law or of the
Certificate of Incorporation or Bylaws of the corporation, to any person with
whom communication is unlawful, the giving of such notice to such person shall
not be required and there shall be no duty to apply to any governmental
authority or agency for a license or permit to give such notice to such person.
Any action or meeting which shall be taken or held without notice to any such
person with whom communication is unlawful shall have the same force and effect
as if such notice had been duly given. In the event that the action taken by the
corporation is such as to require the filing of a certificate under any
provision of the DGCL, the certificate shall state, if such is the fact and if
notice is required, that notice was given to all persons entitled to receive
notice except such persons with whom communication is unlawful.

           (h)    Notice To Person With Undeliverable Address.  Whenever notice
is required to be given, under any provision of law or the Certificate of
Incorporation or Bylaws of the corporation, to any stockholder to whom (i)
notice of two consecutive annual meetings, and all notices of meetings or of the
taking of action by written consent without a meeting to such person during the
period between such two consecutive annual meetings, or (ii) all, and at least
two, payments (if sent by first class mail) of dividends or interest on
securities during a twelve-

                                      21.
<PAGE>

month period, have been mailed addressed to such person at his address as shown
on the records of the corporation and have been returned undeliverable, the
giving of such notice to such person shall not be required. Any action or
meeting which shall be taken or held without notice to such person shall have
the same force and effect as if such notice had been duly given. If any such
person shall deliver to the corporation a written notice setting forth his then
current address, the requirement that notice be given to such person shall be
reinstated. In the event that the action taken by the corporation is such as to
require the filing of a certificate under any provision of the DGCL, the
certificate need not state that notice was not given to persons to whom notice
was not required to be given pursuant to this paragraph. (Del. Code Ann, tit. 8,
Section 230)

                                 ARTICLE XIII

                                  AMENDMENTS


     Section 45.  Amendments.  Subject to paragraph (h) of Section 43 of the
Bylaws, the Bylaws may be altered or amended or new Bylaws adopted by the
affirmative vote of at least sixty-six and two-thirds percent (66-2/3%) of the
voting power of all of the then-outstanding shares of the voting stock of the
corporation entitled to vote. The Board of Directors shall also have the power
to adopt, amend, or repeal Bylaws.

                               LOANS TO OFFICERS

     Section 45.  Loans To Officers.  The corporation may lend money to, or
guarantee any obligation of, or otherwise assist any officer or other employee
of the corporation or of its subsidiaries, including any officer or employee who
is a Director of the corporation or its subsidiaries, whenever, in the judgment
of the Board of Directors, such loan, guarantee or assistance may reasonably be
expected to benefit the corporation. The loan, guarantee or other assistance may
be with or without interest and may be unsecured, or secured in such manner as
the Board of Directors shall approve, including, without limitation, a pledge of
shares of stock of the corporation. Nothing in these Bylaws shall be deemed to
deny, limit or restrict the powers of guaranty or warranty of the corporation at
common law or under any statute. (Del. Code Ann., tit. 8, Section 143)

                              INDEMNITY AGREEMENT

     This Agreement is made and entered into this __________ day of __________,
2000 by and between Mercata Corporation, a Delaware corporation (the
"Corporation"), and __________ ("Agent").

                                   Recitals

     Whereas, Agent performs a valuable service to the Corporation in __________
capacity as __________ of the Corporation;

     Whereas, the stockholders of the Corporation have adopted bylaws (the
"Bylaws") providing for the indemnification of the directors, officers,
employees and other agents of the Corporation, including persons serving at the
request of the Corporation in such capacities with other corporations or
enterprises, as authorized by the Delaware General Corporation Law, as amended
(the "Code");

     Whereas, the Bylaws and the Code, by their non-exclusive nature, permit
contracts between the Corporation and its agents, officers, employees and other
agents with respect to indemnification of such persons; and

     Whereas, in order to induce Agent to continue to serve as __________ of the
Corporation, the Corporation has determined and agreed to enter into this
Agreement with Agent;

     Now, Therefore, in consideration of Agent's continued service as __________
after the date hereof, the parties hereto agree as follows:

                                   Agreement

     1.   Services to the Corporation.  Agent will serve, at the will of the
Corporation or under separate contract, if any such contract exists, as
__________ of the Corporation or as a director, officer or other fiduciary of an
affiliate of the Corporation (including any employee benefit plan of the
Corporation) faithfully and to the best of his ability so long as he is duly
elected and qualified in accordance with the provisions of the Bylaws or other
applicable charter documents of the Corporation or such affiliate; provided,
however, that Agent may at any time and for any reason resign from such position
(subject to any contractual obligation that Agent may have assumed apart from
this Agreement) and that the Corporation or any affiliate shall have no
obligation under this Agreement to continue Agent in any such position.

     2.   Indemnity of Agent.  The Corporation hereby agrees to hold harmless
and indemnify Agent to the fullest extent authorized or permitted by the
provisions of the Bylaws and the Code, as the same may be amended from time to
time (but, only to the extent that such amendment permits the Corporation to
provide broader indemnification rights than the Bylaws or the Code permitted
prior to adoption of such amendment).

                                       1.
<PAGE>

     3.   Additional Indemnity.  In addition to and not in limitation of the
indemnification otherwise provided for herein, and subject only to the
exclusions set forth in Section 4 hereof, the Corporation hereby further agrees
to hold harmless and indemnify Agent:

          (a)  against any and all expenses (including attorneys' fees), witness
fees, damages, judgments, fines and amounts paid in settlement and any other
amounts that Agent becomes legally obligated to pay because of any claim or
claims made against or by him in connection with any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, arbitrational,
administrative or investigative (including an action by or in the right of the
Corporation) to which Agent is, was or at any time becomes a party, or is
threatened to be made a party, by reason of the fact that Agent is, was or at
any time becomes a director, officer, employee or other agent of Corporation, or
is or was serving or at any time serves at the request of the Corporation as a
director, officer, employee or other agent of another corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise; and

          (b)  otherwise to the fullest extent as may be provided to Agent by
the Corporation under the non-exclusivity provisions of the Code and Section 41
of the Bylaws.

     4.   Limitations on Additional Indemnity.  No indemnity pursuant to Section
3 hereof shall be paid by the Corporation:

          (a)  on account of any claim against Agent solely for an accounting of
profits made from the purchase or sale by Agent of securities of the Corporation
pursuant to the provisions of Section 16(b) of the Securities Exchange Act of
1934 and amendments thereto or similar provisions of any federal, state or local
statutory law;

          (b)  on account of Agent's conduct that is established by a final
judgment as knowingly fraudulent or deliberately dishonest or that constituted
willful misconduct;

          (c)  on account of Agent's conduct that is established by a final
judgment as constituting a breach of Agent's duty of loyalty to the Corporation
or resulting in any personal profit or advantage to which Agent was not legally
entitled;

          (d)  for which payment is actually made to Agent under a valid and
collectible insurance policy or under a valid and enforceable indemnity clause,
bylaw or agreement, except in respect of any excess beyond payment under such
insurance, clause, bylaw or agreement;

          (e)  if indemnification is not lawful (and, in this respect, both the
Corporation and Agent have been advised that the Securities and Exchange
Commission believes that indemnification for liabilities arising under the
federal securities laws is against public policy and is, therefore,
unenforceable and that claims for indemnification should be submitted to
appropriate courts for adjudication); or

          (f)  in connection with any proceeding (or part thereof) initiated by
Agent, or any proceeding by Agent against the Corporation or its directors,
officers, employees or other agents, unless (i) such indemnification is
expressly required to be made by law, (ii) the proceeding was authorized by the
Board of Directors of the Corporation, (iii) such

                                       2.
<PAGE>

indemnification is provided by the Corporation, in its sole discretion, pursuant
to the powers vested in the Corporation under the Code, or (iv) the proceeding
is initiated pursuant to Section 9 hereof.

     5.   Continuation of Indemnity.  All agreements and obligations of the
Corporation contained herein shall continue during the period Agent is a
director, officer, employee or other agent of the Corporation (or is or was
serving at the request of the Corporation as a director, officer, employee or
other agent of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise) and shall continue thereafter so long as Agent
shall be subject to any possible claim or threatened, pending or completed
action, suit or proceeding, whether civil, criminal, arbitrational,
administrative or investigative, by reason of the fact that Agent was serving in
the capacity referred to herein.

     6.   Partial Indemnification.  Agent shall be entitled under this Agreement
to indemnification by the Corporation for a portion of the expenses (including
attorneys' fees), witness fees, damages, judgments, fines and amounts paid in
settlement and any other amounts that Agent becomes legally obligated to pay in
connection with any action, suit or proceeding referred to in Section 3 hereof
even if not entitled hereunder to indemnification for the total amount thereof,
and the Corporation shall indemnify Agent for the portion thereof to which Agent
is entitled.

     7.   Notification and Defense of Claim.  Not later than thirty (30) days
after receipt by Agent of notice of the commencement of any action, suit or
proceeding, Agent will, if a claim in respect thereof is to be made against the
Corporation under this Agreement, notify the Corporation of the commencement
thereof; but the omission so to notify the Corporation will not relieve it from
any liability which it may have to Agent otherwise than under this Agreement.
With respect to any such action, suit or proceeding as to which Agent notifies
the Corporation of the commencement thereof:

          (a)  the Corporation will be entitled to participate therein at its
own expense;

          (b)  except as otherwise provided below, the Corporation may, at its
option and jointly with any other indemnifying party similarly notified and
electing to assume such defense, assume the defense thereof, with counsel
reasonably satisfactory to Agent. After notice from the Corporation to Agent of
its election to assume the defense thereof, the Corporation will not be liable
to Agent under this Agreement for any legal or other expenses subsequently
incurred by Agent in connection with the defense thereof except for reasonable
costs of investigation or otherwise as provided below. Agent shall have the
right to employ separate counsel in such action, suit or proceeding but the fees
and expenses of such counsel incurred after notice from the Corporation of its
assumption of the defense thereof shall be at the expense of Agent unless (i)
the employment of counsel by Agent has been authorized by the Corporation, (ii)
Agent shall have reasonably concluded, and so notified the Corporation, that
there is an actual conflict of interest between the Corporation and Agent in the
conduct of the defense of such action or (iii) the Corporation shall not in fact
have employed counsel to assume the defense of such action, in each of which
cases the fees and expenses of Agent's separate counsel shall be at the expense
of the Corporation. The Corporation shall not be entitled to assume the defense
of any

                                       3.
<PAGE>

action, suit or proceeding brought by or on behalf of the Corporation or as to
which Agent shall have made the conclusion provided for in clause (ii) above;
and

          (c)  the Corporation shall not be liable to indemnify Agent under this
Agreement for any amounts paid in settlement of any action or claim effected
without its written consent, which shall not be unreasonably withheld.  The
Corporation shall be permitted to settle any action except that it shall not
settle any action or claim in any manner which would impose any penalty or
limitation on Agent without Agent's written consent, which may be given or
withheld in Agent's sole discretion.

     8.   Expenses.  The Corporation shall advance, prior to the final
disposition of any proceeding, promptly following request therefor, all expenses
incurred by Agent in connection with such proceeding upon receipt of an
undertaking by or on behalf of Agent to repay said amounts if it shall be
determined ultimately that Agent is not entitled to be indemnified under the
provisions of this Agreement, the Bylaws, the Code or otherwise.

     9.   Enforcement.  Any right to indemnification or advances granted by this
Agreement to Agent shall be enforceable by or on behalf of Agent in any court of
competent jurisdiction if (i) the claim for indemnification or advances is
denied, in whole or in part, or (ii) no disposition of such claim is made within
ninety (90) days of request therefor.  Agent, in such enforcement action, if
successful in whole or in part, shall be entitled to be paid also the expense of
prosecuting his claim.  It shall be a defense to any action for which a claim
for indemnification is made under Section 3 hereof (other than an action brought
to enforce a claim for expenses pursuant to Section 8 hereof, provided that the
required undertaking has been tendered to the Corporation) that Agent is not
entitled to indemnification because of the limitations set forth in Section 4
hereof.  Neither the failure of the Corporation (including its Board of
Directors or its stockholders) to have made a determination prior to the
commencement of such enforcement action that indemnification of Agent is proper
in the circumstances, nor an actual determination by the Corporation (including
its Board of Directors or its stockholders) that such indemnification is
improper shall be a defense to the action or create a presumption that Agent is
not entitled to indemnification under this Agreement or otherwise.

     10.  Subrogation.  In the event of payment under this Agreement, the
Corporation shall be subrogated to the extent of such payment to all of the
rights of recovery of Agent, who shall execute all documents required and shall
do all acts that may be necessary to secure such rights and to enable the
Corporation effectively to bring suit to enforce such rights.

     11.  Non-Exclusivity of Rights.  The rights conferred on Agent by this
Agreement shall not be exclusive of any other right which Agent may have or
hereafter acquire under any statute, provision of the Corporation's Certificate
of Incorporation or Bylaws, agreement, vote of stockholders or directors, or
otherwise, both as to action in his official capacity and as to action in
another capacity while holding office.

     12.  Survival of Rights.

          (a)  The rights conferred on Agent by this Agreement shall continue
after Agent has ceased to be a director, officer, employee or other agent of the
Corporation or to serve

                                       4.
<PAGE>

at the request of the Corporation as a director, officer, employee or other
agent of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise and shall inure to the benefit of Agent's
heirs, executors and administrators.

          (b)  The Corporation shall require any successor (whether direct or
indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business or assets of the Corporation, expressly to
assume and agree to perform this Agreement in the same manner and to the same
extent that the Corporation would be required to perform if no such succession
had taken place.

     13.  Separability.  Each of the provisions of this Agreement is a separate
and distinct agreement and independent of the others, so that if any provision
hereof shall be held to be invalid for any reason, such invalidity or
unenforceability shall not affect the validity or enforceability of the other
provisions hereof.  Furthermore, if this Agreement shall be invalidated in its
entirety on any ground, then the Corporation shall nevertheless indemnify Agent
to the fullest extent provided by the Bylaws, the Code or any other applicable
law.

     14.  Governing Law.  This Agreement shall be interpreted and enforced in
accordance with the laws of the State of Delaware.

     15.  Amendment and Termination.  No amendment, modification, termination or
cancellation of this Agreement shall be effective unless in writing signed by
both parties hereto.

     16.  Identical Counterparts.  This Agreement may be executed in one or more
counterparts, each of which shall for all purposes be deemed to be an original
but all of which together shall constitute but one and the same Agreement.  Only
one such counterpart need be produced to evidence the existence of this
Agreement.

     17.  Headings.  The headings of the sections of this Agreement are inserted
for convenience only and shall not be deemed to constitute part of this
Agreement or to affect the construction hereof.

     18.  Notices.  All notices, requests, demands and other communications
hereunder shall be in writing and shall be deemed to have been duly given (i)
upon delivery if delivered by hand to the party to whom such communication was
directed or (ii) upon the third business day after the date on which such
communication was mailed if mailed by certified or registered mail with postage
prepaid:

(b)  Powers of Board.  The Board shall have the power, subject to, and within
     the limitations of, the express provisions of the Plan:

     (i)   To determine from time to time which of the persons eligible under
           the Plan shall be granted Stock Awards; when and how each Stock Award

(c)  Delegation to Committee.

     (i)  General.  The Board may delegate administration of the Plan to a
          Committee or Committees of one (1) or more members of the Board, and
          the term "Committee" shall apply to any person or persons to whom such
          authority has been delegated. If administration is delegated to a
          Committee, the Committee shall have, in connection with the
          administration of the Plan, the powers theretofore possessed by the
          Board, including the power to delegate to a subcommittee any of the
          administrative powers the Committee is authorized to exercise (and

          Committee or subcommittee), subject, however, to such resolutions, not
          inconsistent with the provisions of the Plan, as may be adopted from

          time and revest in the Board the administration of the Plan.

     (ii) Committee Composition when Common Stock is Publicly Traded.  At such
          time as the Common Stock is publicly traded, in the discretion of the
          Board, a Committee may consist solely of two or more Outside
          Directors, in accordance with Section 162(m) of the Code, and/or
          solely of two or more Non-Employee Directors, in accordance with Rule
          16b-3. Within the scope of such authority, the Board or the Committee
          may (1) delegate to a committee of one or more members of the Board
          who are not Outside Directors the authority to grant Stock Awards to
          eligible persons who are either (a) not then Covered Employees and are
          not expected to be Covered Employees at the time of recognition of
          income resulting from such Stock Award or (b) not persons with respect
          to whom the Company wishes to comply with Section 162(m) of the Code
          and/or (2) delegate to a committee of one or more members of the Board
          who are not Non-Employee Directors the authority to grant Stock Awards
          to eligible persons who are not then subject to Section 16 of the
          Exchange Act.

(d)  Effect of Board's Decision.  All determinations, interpretations and
     constructions made by the Board in good faith shall not be subject to
     review by any person and shall be final, binding and conclusive on all
     persons.

4.  Shares Subject to the Plan.

(a)  Share Reserve.  Subject to the provisions of Section 12 relating to
     adjustments upon changes in Common Stock, the Common Stock that may be
     issued pursuant to Stock Awards shall not exceed in the aggregate Four
     Million Five Hundred Thousand (4,500,000) shares of Common Stock, plus an
     annual increase to be added each January 1, beginning January 1, 2002,
     equal to the lesser of One Million Five Hundred Thousand (1,500,000) shares
     or five percent (5%) of the total number of shares of Common Stock
     outstanding on such January 1.  Notwithstanding the foregoing, the Board
     may designate a smaller number of shares of Common Stock to be added to the
     share reserve as of a particular January 1.

(b)  Reversion of Shares to the Share Reserve.  If any Stock Award shall for any
     reason expire or otherwise terminate, in whole or in part, without having
     been exercised in full,

                                       5
<PAGE>

     the shares of Common Stock not acquired under such Stock Award shall revert
     to and again become available for issuance under the Plan.

(c)  Source of Shares.  The shares of Common Stock subject to the Plan may be
     unissued shares or reacquired shares, bought on the market or otherwise.

5.  Eligibility.

(a)  Eligibility for Specific Stock Awards.  Incentive Stock Options may be
     granted only to Employees.  Stock Awards other than Incentive Stock Options
     may be granted to Employees, Directors and Consultants.

(b)  Ten Percent Stockholders.  A Ten Percent Shareholder shall not be granted
     an Incentive Stock Option unless the exercise price of such Option is at
     least one hundred ten percent (110%) of the Fair Market Value of the Common
     Stock at the date of grant and the Option is not exercisable after the
     expiration of five (5) years from the date of grant.

(c)  Section 162(m) Limitation.  Subject to the provisions of Section 12
     relating to adjustments upon changes in the shares of Common Stock, no
     Employee shall be eligible to be granted Options covering more than two
     million (2,000,000) shares of Common Stock during any calendar year.

(d)  Consultants.

     (i)  A Consultant shall not be eligible for the grant of a Stock Award if,
          at the time of grant, a Form S-8 Registration Statement under the
          Securities Act ("Form S-8") is not available to register either the
          offer or the sale of the Company's securities to such Consultant
          because of the nature of the services that the Consultant is providing
          to the Company, or because the Consultant is not a natural person, or
          as otherwise provided by the rules governing the use of Form S-8,
          unless the Company determines both (i) that such grant (A) shall be
          registered in another manner under the Securities Act (e.g., on a Form
          S-3 Registration Statement) or (B) does not require registration under
          the Securities Act in order to comply with the requirements of the
          Securities Act, if applicable, and (ii) that such grant complies with
          the securities laws of all other relevant jurisdictions.

     (ii) Form S-8 generally is available to consultants and advisors only if
          (i) they are natural persons; (ii) they provide bona fide services to
          the issuer, its parents, its majority-owned subsidiaries or majority-
          owned subsidiaries of the issuer's parent; and (iii) the services are
          not in connection with the offer or sale of securities in a capital-
          raising transaction, and do not directly or indirectly promote or
          maintain a market for the issuer's securities.

6.  Option Provisions.

     Each Option shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate.  All Options shall be separately
designated Incentive Stock Options or Nonstatutory Stock Options at the time of
grant, and, if certificates are issued, a separate certificate or certificates
will be issued for shares of Common Stock purchased on exercise of each type of
Option.  The provisions of separate Options need not be identical, but

                                       6
<PAGE>

each Option shall include (through incorporation of provisions hereof by
reference in the Option or otherwise) the substance of each of the following
provisions:

(a)  Term.  Subject to the provisions of subsection 5(b) regarding Ten Percent
     Stockholders, no Incentive Stock Option shall be exercisable after the
     expiration of ten (10) years from the date it was granted.

(b)  Exercise Price of an Incentive Stock Option.  Subject to the provisions of
     subsection 5(b) regarding Ten Percent Stockholders, the exercise price of
     each Incentive Stock Option shall be not less than one hundred percent
     (100%) of the Fair Market Value of the Common Stock subject to the Option
     on the date the Option is granted.  Notwithstanding the foregoing, an
     Incentive Stock Option may be granted with an exercise price lower than
     that set forth in the preceding sentence if such Option is granted pursuant
     to an assumption or substitution for another option in a manner satisfying
     the provisions of Section 424(a) of the Code.

(c)  Exercise Price of a Nonstatutory Stock Option.  The exercise price of each
     Nonstatutory Stock Option shall be not less than eighty-five percent (85%)
     of the Fair Market Value of the Common Stock subject to the Option on the
     date the Option is granted.  Notwithstanding the foregoing, a Nonstatutory
     Stock Option may be granted with an exercise price lower than that set
     forth in the preceding sentence if such Option is granted pursuant to an
     assumption or substitution for another option in a manner satisfying the
     provisions of Section 424(a) of the Code.

(d)  Consideration.  The purchase price of Common Stock acquired pursuant to an
     Option shall be paid, to the extent permitted by applicable statutes and
     regulations, either (i) in cash or check at the time the Option is
     exercised or (ii) at the discretion of the Board at the time of the grant
     of the Option (or subsequently in the case of a Nonstatutory Stock Option)
     (1) by delivery to the Company of other Common Stock, (2) according to a
     deferred payment or other similar arrangement with the Optionholder or (3)
     in any other form of legal consideration that may be acceptable to the
     Board.  Unless otherwise specifically provided in the Option, the purchase
     price of Common Stock acquired pursuant to an Option that is paid by
     delivery to the Company of other Common Stock acquired, directly or
     indirectly from the Company, shall be paid only by shares of the Common
     Stock of the Company that have been held for more than six (6) months (or
     such longer or shorter period of time required to avoid a charge to
     earnings for financial accounting purposes).  At any time that the Company
     is incorporated in Delaware, payment of the Common Stock's "par value," as
     defined in the Delaware General Corporation Law, shall not be made by
     deferred payment.

     In the case of any deferred payment arrangement, interest shall be
     compounded at least annually and shall be charged at the minimum rate of
     interest necessary to avoid the treatment as interest, under any applicable
     provisions of the Code, of any amounts other than amounts stated to be
     interest under the deferred payment arrangement.

(e)  Transferability of an Incentive Stock Option.  An Incentive Stock Option
     shall not be transferable except by will or by the laws of descent and
     distribution and shall be exercisable during the lifetime of the
     Optionholder only by the Optionholder.  Notwithstanding

                                       7
<PAGE>

     the foregoing, the Optionholder may, by delivering written notice to the
     Company, in a form satisfactory to the Company, designate a third party
     who, in the event of the death of the Optionholder, shall thereafter be
     entitled to exercise the Option.

(f)  Transferability of a Nonstatutory Stock Option.  A Nonstatutory Stock
     Option shall be transferable to the extent provided in the Option
     Agreement.  If the Nonstatutory Stock Option does not provide for
     transferability, then the Nonstatutory Stock Option shall not be
     transferable except by will or by the laws of descent and distribution and
     shall be exercisable during the lifetime of the Optionholder only by the
     Optionholder.  Notwithstanding the foregoing, the Optionholder may, by
     delivering written notice to the Company, in a form satisfactory to the
     Company, designate a third party who, in the event of the death of the
     Optionholder, shall thereafter be entitled to exercise the Option.

(g)  Vesting Generally.  The total number of shares of Common Stock subject to
     an Option may, but need not, vest and therefore become exercisable in
     periodic installments that may, but need not, be equal.  The Option may be
     subject to such other terms and conditions on the time or times when it may
     be exercised (which may be based on performance or other criteria) as the
     Board may deem appropriate.  The vesting provisions of individual Options
     may vary.  The provisions of this subsection 6(g) are subject to any Option
     provisions governing the minimum number of shares of Common Stock as to
     which an Option may be exercised. Notwithstanding the foregoing, in the
     event an Employee who is also a member of the Board terminates his or her
     employment for any reason but remains as a member of the Board, the vesting
     on such individual's Option shall (unless the Board determines otherwise)
     cease as of the date of the termination of his or her employment but such
     individual shall be permitted to exercise his or her Option to purchase the
     vested number of shares of Common Stock subject to the Option for such
     period of time as provided above or in his or her Option Agreement.

(h)  Termination of Continuous Service.  In the event an Optionholder's
     Continuous Service terminates (other than upon the Optionholder's death or
     Disability), the Optionholder may exercise his or her Option (to the extent
     that the Optionholder was entitled to exercise such Option as of the date
     of termination) but only within such period of time ending on the earlier
     of (i) the date three (3) months following the termination of the
     Optionholder's Continuous Service (or such longer or shorter period
     specified in the Option Agreement), or (ii) the expiration of the term of
     the Option as set forth in the Option Agreement.  If, after termination,
     the Optionholder does not exercise his or her Option within the time
     specified in the Option Agreement, the Option shall terminate.

(i)  Extension of Termination Date.  An Optionholder's Option Agreement may also
     provide that if the exercise of the Option following the termination of the
     Optionholder's Continuous Service (other than upon the Optionholder's death
     or Disability) would be prohibited at any time solely because the issuance
     of shares of Common Stock would violate the registration requirements under
     the Securities Act, then the Option shall terminate on the earlier of (i)
     the expiration of the term of the Option set forth in subsection 6(a) or
     (ii) the expiration of a period of three (3) months after the termination
     of the Optionholder's Continuous Service during which the exercise of the
     Option would not be in violation of such registration requirements.

                                       8
<PAGE>

(j)  Disability of Optionholder.  In the event that an Optionholder's Continuous
     Service terminates as a result of the Optionholder's Disability, the
     Optionholder may exercise his or her Option (to the extent that the
     Optionholder was entitled to exercise such Option as of the date of
     termination), but only within such period of time ending on the earlier of
     (i) the date twelve (12) months following such termination (or such longer
     or shorter period specified in the Option Agreement) or (ii) the expiration
     of the term of the Option as set forth in the Option Agreement.  If, after
     termination, the Optionholder does not exercise his or her Option within
     the time specified herein, the Option shall terminate.

(k)  Death of Optionholder.  In the event (i) an Optionholder's Continuous
     Service terminates as a result of the Optionholder's death or (ii) the
     Optionholder dies within the period (if any) specified in the Option
     Agreement after the termination of the Optionholder's Continuous Service
     for a reason other than death, then the Option may be exercised (to the
     extent the Optionholder was entitled to exercise such Option as of the date
     of death) by the Optionholder's estate, by a person who acquired the right
     to exercise the Option by bequest or inheritance or by a person designated
     to exercise the Option upon the Optionholder's death pursuant to subsection
     6(e) or 6(f), but only within the period ending on the earlier of (1) the
     date eighteen (18) months following the date of death (or such longer or
     shorter period specified in the Option Agreement) or (2) the expiration of
     the term of such Option as set forth in the Option Agreement.  If, after
     death, the Option is not exercised within the time specified herein, the
     Option shall terminate.

(l)  Early Exercise.  The Option may, but need not, include a provision whereby
     the Optionholder may elect at any time before the Optionholder's Continuous
     Service terminates to exercise the Option as to any part or all of the
     shares of Common Stock subject to the Option prior to the full vesting of
     the Option.  Any unvested shares of Common Stock so purchased may be
     subject to a repurchase option in favor of the Company or to any other
     restriction the Board determines to be appropriate.  The Company will not
     exercise its repurchase option until at least six (6) months (or such
     longer or shorter period of time required to avoid a charge to earnings for
     financial accounting purposes) have elapsed following exercise of the
     Option unless the Board otherwise specifically provides in the Option.

(m)  Re-Load Options.

     (i)   Without in any way limiting the authority of the Board to make or not
           to make grants of Options hereunder, the Board shall have the
           authority (but not an obligation) to include as part of any Option
           Agreement a provision entitling the Optionholder to a further Option
           (a "Re-Load Option") in the event the Optionholder exercises the
           Option evidenced by the Option Agreement, in whole or in part, by
           surrendering other shares of Common Stock in accordance with this
           Plan and the terms and conditions of the Option Agreement. Unless
           otherwise specifically provided in the Option, the Optionholder shall
           not surrender shares of Common Stock acquired, directly or indirectly
           from the Company, unless such shares have been held for more than six
           (6) months (or such longer or shorter period of time required to
           avoid a charge to earnings for financial accounting purposes).

     (ii)  Any such Re-Load Option shall (1) provide for a number of shares of
           Common Stock equal to the number of shares of Common Stock
           surrendered as part or all of the

                                       9
<PAGE>

           exercise price of such Option; (2) have an expiration date which is
           the same as the expiration date of the Option the exercise of which
           gave rise to such Re-Load Option; and (3) have an exercise price
           which is equal to one hundred percent (100%) of the Fair Market Value
           of the Common Stock subject to the Re-Load Option on the date of
           exercise of the original Option. Notwithstanding the foregoing, a Re-
           Load Option shall be subject to the same exercise price and term
           provisions heretofore described for Options under the Plan.

     (iii) Any such Re-Load Option may be an Incentive Stock Option or a
           Nonstatutory Stock Option, as the Board may designate at the time of
           the grant of the original Option; provided, however, that the
           designation of any Re-Load Option as an Incentive Stock Option shall
           be subject to the one hundred thousand dollar ($100,000) annual
           limitation on the exercisability of Incentive Stock Options described
           in subsection 9(d) and in Section 422(d) of the Code. There shall be
           no Re-Load Options on a Re-Load Option. Any such Re-Load Option shall
           be subject to the availability of sufficient shares of Common Stock
           under subsection 4(a) and the "Section 162(m) Limitation" on the
           grants of Options under subsection 5(c) and shall be subject to such
           other terms and conditions as the Board may determine which are not
           inconsistent with the express provisions of the Plan regarding the
           terms of Options.

7.  Non-Employee Director Stock Options.

     Without any further action of the Board, each Non-Employee Director shall
be granted Nonstatutory Stock Options as described in subsections 7(a) and 7(b)
(collectively, "Non-Employee Director Options"). The provisions of this Section
7 shall apply only to a Non-Employee Director Option.  Each Non-Employee
Director Option shall include the substance of the terms set forth in
subsections 7(c) through 7(k).

(a)  Initial Grants.  On the IPO Date, each person who is elected or appointed
     for the first time to be a Non-Employee Director automatically shall, upon
     the date of his or her initial election or appointment to be a Non-Employee
     Director by the Board or stockholders of the Company, be granted an Initial
     Grant to purchase forty thousand (40,000) shares of Common Stock on the
     terms and conditions set forth herein.  For purposes of the foregoing
     sentence, on the IPO Date, each person then serving as a Non-Employee
     Director and who has not previously been granted options to acquire Common
     Stock shall be deemed to have been initially elected as a Non-Employee
     Director on such date.

(b)  Annual Grants.  After the IPO Date, each person who is a Non-Employee
     Director on the Board on the day after the annual stockholders' meeting,
     shall, on that date, be granted an Annual Grant to purchase five thousand
     (5,000) shares of Common Stock on the terms and conditions set forth herein
     for each committee of the Board on which he or she serves; provided, that
     each Non-Employee Director who is on a committee of the Board on the IPO
     Date shall be granted his or her first such Annual Grant on the IPO Date
     for each committee on which he or she serves.   Notwithstanding the
     foregoing, each Non-Employee Director who is first elected or appointed to
     a committee after an annual stockholders' meeting shall be entitled to the
     Annual Grant for service on that committee which shall be reduced, pro-rata
     on a twelve-month basis, for each month following the annual stockholders'
     meeting that such person did not serve on the committee; the pro-rated
     Annual Grant shall vest monthly over the remainder of the twelve (12) month
     period immediately following the annual stockholders' meeting.

                                       10
<PAGE>

(c)  Term.  Each Non-Employee Director Option shall have a term of ten (10)
     years from the date it is granted.

(d)  Exercise Price.  The exercise price of each Non-Employee Director Option
     shall be one hundred percent (100%) of the Fair Market Value of the stock
     subject to the Non-Employee Director Option on the date of grant.
     Notwithstanding the foregoing, a Non-Employee Director Option may be
     granted with an exercise price lower than that set forth in the preceding
     sentence if such Non-Employee Director Option is granted pursuant to an
     assumption or substitution for another option in a manner satisfying the
     provisions of Section 424(a) of the Code.  The exercise price for each
     Initial Grant shall be the initial offering price for the initial public
     offering of the Company's Common Stock as set forth in the Company's
     prospectus for the initial public offering.

(e)  Vesting.  Each Initial Grant shall vest one-fourth (1/4th) per year from
     the date on which the director first served on the Board.  Each Annual
     Grant shall vest fully one (1) year from the date on which it is granted.

(f)  Consideration.  The purchase price of stock acquired pursuant to a Non-
     Employee Director Option may be paid, to the extent permitted by applicable
     statutes and regulations, in any combination of (i) cash or check, (ii)
     delivery to the Company of other Common Stock, (ii) deferred payment or
     (iv) any other form of legal consideration that may be acceptable to the
     Board and provided in the Non-Employee Director Option Agreement; provided,
     however, that at any time that the Company is incorporated in Delaware,
     payment of the Common Stock's "par value," as defined in the Delaware
     General Corporation Law, shall not be made by deferred payment. In the case
     of any deferred payment arrangement, interest shall be compounded at least
     annually and shall be charged at the minimum rate of interest necessary to
     avoid the treatment as interest, under any applicable provisions of the
     Code, of any amounts other than amounts stated to be interest under the
     deferred payment arrangement.

(g)  Transferability.  A Non-Employee Director Option shall not be transferable
     except by will or by the laws of descent and distribution and shall be
     exercisable during the lifetime of the Non-Employee Director only by the
     Non-Employee Director.  Notwithstanding the foregoing, the Non-Employee
     Director may, by delivering written notice to the Company, in a form
     satisfactory to the Company, designate a third party who, in the event of
     the death of the Non-Employee Director, shall thereafter be entitled to
     exercise the Non-Employee Director Option.

(h)  Termination of Continuous Service.  In the event a Non-Employee Director's
     Continuous Service terminates (other than upon the Non-Employee Director's
     death or Disability), the Non-Employee Director may exercise his or her
     Non-Employee Director Option (to the extent that the Non-Employee Director
     was entitled to exercise it as of the date of termination) but only within
     such period of time ending on the earlier of (i) the date three (3) months
     following the termination of the Non-Employee Director's Continuous
     Service, or (ii) the expiration of the term of the Non-Employee Director
     Option as set forth in the Non-Employee Director Option Agreement.  If,
     after termination, the Non-Employee Director does not exercise his or her
     Non-Employee Director Option within the time specified in the Non-Employee
     Director Option Agreement, the Non-Employee Director Option shall
     terminate.

                                       11
<PAGE>

(i)  Extension of Termination Date. If the exercise of the Non-Employee Director
     Option following the termination of the Non-Employee Director's Continuous
     Service (other than upon the Non-Employee Director's death or Disability)
     would be prohibited at any time solely because the issuance of shares would
     violate the registration requirements under the Securities Act, then the
     Non-Employee Director Option shall terminate on the earlier of (i) the
     expiration of the term of the Non-Employee Director Option set forth in
     subsection 7(c) or (ii) the expiration of a period of three (3) months
     after the termination of the Non-Employee Director's Continuous Service
     during which the exercise of the Non-Employee Director Option would not
     violate such registration requirements.

(j)  Disability of Non-Employee Director.  In the event a Non-Employee
     Director's Continuous Service terminates as a result of the Non-Employee
     Director's Disability, the Non-Employee Director may exercise his or her
     Non-Employee Director Option (to the extent that the Non-Employee Director
     was entitled to exercise it as of the date of termination), but only within
     such period of time ending on the earlier of (i) the date twelve (12)
     months following such termination or (ii) the expiration of the term of the
     Non-Employee Director Option as set forth in the Non-Employee Director
     Option Agreement.  If, after termination, the Non-Employee Director does
     not exercise his or her Non-Employee Director Option within the time
     specified herein, the Non-Employee Director Option shall terminate.

(k)  Death of Non-Employee Director.  In the event (i) a Non-Employee Director's
     Continuous Service terminates as a result of the Non-Employee Director's
     death or (ii) the Non-Employee Director dies within the three-month period
     after the termination of the Non-Employee Director's Continuous Service for
     a reason other than death, then the Non-Employee Director Option may be
     exercised (to the extent the Non-Employee Director was entitled to exercise
     the Non-Employee Director Option as of the date of death) by the Non-
     Employee Director's estate, by a person who acquired the right to exercise
     the Non-Employee Director Option by bequest or inheritance or by a person
     designated to exercise the Non-Employee Director Option upon the Non-
     Employee Director's death, but only within the period ending on the earlier
     of (1) the date eighteen (18) months following the date of death or (2) the
     expiration of the term of such Non-Employee Director Option as set forth in
     the Non-Employee Director Option Agreement.  If, after death, the Non-
     Employee Director Option is not exercised within the time specified herein,
     the Non-Employee Director Option shall terminate.

8.  Provisions of Stock Awards other than Options.

(a)  Stock Bonus Awards.  Each stock bonus agreement shall be in such form and
     shall contain such terms and conditions as the Board shall deem
     appropriate.  The terms and conditions of stock bonus agreements may change
     from time to time, and the terms and conditions of separate stock bonus
     agreements need not be identical, but each stock bonus agreement shall
     include (through incorporation of provisions hereof by reference in the
     agreement or otherwise) the substance of each of the following provisions:

     (i)   Consideration.  A stock bonus may be awarded in consideration for
           past services actually rendered to the Company or an Affiliate for
           its benefit.

                                       12
<PAGE>

     (ii)  Vesting.  Shares of Common Stock awarded under the stock bonus
           agreement may, but need not, be subject to a share repurchase option
           in favor of the Company in accordance with a vesting schedule to be
           determined by the Board.

     (iii) Termination of Participant's Continuous Service.  In the event a
           Participant's Continuous Service terminates, the Company may
           reacquire any or all of the shares of Common Stock held by the
           Participant which have not vested as of the date of termination under
           the terms of the stock bonus agreement.

     (iv)  Transferability.  Rights to acquire shares of Common Stock under the
           stock bonus agreement shall be transferable by the Participant only
           upon such terms and conditions as are set forth in the stock bonus
           agreement, as the Board shall determine in its discretion, so long as
           Common Stock awarded under the stock bonus agreement remains subject
           to the terms of the stock bonus agreement.

(b)  Restricted Stock Awards.  Each restricted stock purchase agreement shall be
     in such form and shall contain such terms and conditions as the Board shall
     deem appropriate.  The terms and conditions of the restricted stock
     purchase agreements may change from time to time, and the terms and
     conditions of separate restricted stock purchase agreements need not be
     identical, but each restricted stock purchase agreement shall include
     (through incorporation of provisions hereof by reference in the agreement
     or otherwise) the substance of each of the following provisions:

     (i)   Purchase Price.  The purchase price under each restricted stock
           purchase agreement shall be such amount as the Board shall determine
           and designate in such restricted stock purchase agreement. The
           purchase price shall not be less than eighty-five percent (85%) of
           the Common Stock's Fair Market Value on the date such award is made
           or at the time the purchase is consummated.

     (ii)  Consideration.  The purchase price of Common Stock acquired pursuant
           to the restricted stock purchase agreement shall be paid either: (i)
           in cash or check at the time of purchase; (ii) at the discretion of
           the Board, according to a deferred payment or other similar
           arrangement with the Participant; or (iii) in any other form of legal
           consideration that may be acceptable to the Board in its discretion;
           provided, however, that at any time that the Company is incorporated
           in Delaware, then payment of the Common Stock's "par value," as
           defined in the Delaware General Corporation Law, shall not be made by
           deferred payment.

     (iii) Vesting.  Shares of Common Stock acquired under the restricted stock
           purchase agreement may, but need not, be subject to a share
           repurchase option in favor of the Company in accordance with a
           vesting schedule to be determined by the Board.

     (iv)  Termination of Participant's Continuous Service.  In the event a
           Participant's Continuous Service terminates, the Company may
           repurchase or otherwise reacquire any or all of the shares of Common
           Stock held by the Participant which have not vested as of the date of
           termination under the terms of the restricted stock purchase
           agreement.

     (v)   Transferability.  Rights to acquire shares of Common Stock under the
           restricted stock purchase agreement shall be transferable by the
           Participant only upon such terms

                                      13
<PAGE>

           and conditions as are set forth in the restricted stock purchase
           agreement, as the Board shall determine in its discretion, so long as
           Common Stock awarded under the restricted stock purchase agreement
           remains subject to the terms of the restricted stock purchase
           agreement.

9.  Covenants of the Company.

(a)  Availability of Shares.  During the terms of the Stock Awards, the Company
     shall keep available at all times the number of shares of Common Stock
     required to satisfy such Stock Awards.

(b)  Securities Law Compliance.  The Company shall seek to obtain from each
     regulatory commission or agency having jurisdiction over the Plan such
     authority as may be required to grant Stock Awards and to issue and sell
     shares of Common Stock upon exercise of the Stock Awards; provided,
     however, that this undertaking shall not require the Company to register
     under the Securities Act the Plan, any Stock Award or any Common Stock
     issued or issuable pursuant to any such Stock Award.  If, after reasonable
     efforts, the Company is unable to obtain from any such regulatory
     commission or agency the authority which counsel for the Company deems
     necessary for the lawful issuance and sale of Common Stock under the Plan,
     the Company shall be relieved from any liability for failure to issue and
     sell Common Stock upon exercise of such Stock Awards unless and until such
     authority is obtained.

10.  Use of Proceeds from Stock.

     Proceeds from the sale of Common Stock pursuant to Stock Awards shall
constitute general funds of the Company.

11.  Miscellaneous.

(a)  Acceleration of Exercisability and Vesting.  The Board shall have the power
     to accelerate the time at which a Stock Award may first be exercised or the
     time during which a Stock Award or any part thereof will vest in accordance
     with the Plan, notwithstanding the provisions in the Stock Award stating
     the time at which it may first be exercised or the time during which it
     will vest.

(b)  Stockholder Rights.  No Participant shall be deemed to be the holder of, or
     to have any of the rights of a holder with respect to, any shares of Common
     Stock subject to such Stock Award unless and until such Participant has
     satisfied all requirements for exercise of the Stock Award pursuant to its
     terms.

(c)  No Employment or other Service Rights.  Nothing in the Plan or any
     instrument executed or Stock Award granted pursuant thereto shall confer
     upon any Participant any right to continue to serve the Company or an
     Affiliate in the capacity in effect at the time the Stock Award was granted
     or shall affect the right of the Company or an Affiliate to terminate (i)
     the employment of an Employee with or without notice and with or without
     cause, (ii) the service of a Consultant pursuant to the terms of such
     Consultant's agreement with the Company or an Affiliate or (iii) the
     service of a Director pursuant to the Bylaws of the Company or an
     Affiliate, and any applicable provisions of the corporate law of the state
     in which the Company or the Affiliate is incorporated, as the case may be.

(d)  Incentive Stock Option $100,000 Limitation.  To the extent that the
     aggregate Fair Market Value (determined at the time of grant) of Common
     Stock with respect to which Incentive Stock Options are exercisable for the
     first time by any Optionholder during any calendar year (under all plans of
     the Company and its Affiliates) exceeds one hundred thousand dollars
     ($100,000), the Options or portions thereof which exceed such limit
     (according to the order in which they were granted) shall be treated as
     Nonstatutory Stock Options.

(e)  Investment Assurances.  The Company may require a Participant, as a
     condition of exercising or acquiring Common Stock under any Stock Award,
     (i) to give written assurances satisfactory to the Company as to the
     Participant's knowledge and experience in financial and business matters
     and/or to employ a purchaser representative reasonably satisfactory to the
     Company who is knowledgeable and experienced in financial and business
     matters and that he or she is capable of evaluating, alone or together with
     the purchaser representative, the merits and risks of exercising the Stock
     Award; and (ii) to give written assurances satisfactory to the Company
     stating that the Participant is acquiring Common Stock subject to the Stock
     Award for the Participant's own account and not with any present intention
     of selling or otherwise distributing the Common Stock.  The foregoing
     requirements, and any assurances given pursuant to such requirements, shall
     be inoperative if (1) the issuance of the shares of Common Stock upon the
     exercise or acquisition of Common Stock under the Stock Award has been
     registered under a then currently effective registration statement under
     the Securities Act or (2) as to any particular requirement, a determination
     is made by counsel for the Company that such requirement need not be met in
     the circumstances under the then applicable securities laws.  The Company
     may, upon advice of counsel to the Company, place legends on stock
     certificates issued under the Plan as such counsel deems necessary or
     appropriate in order to comply with applicable securities laws, including,
     but not limited to, legends restricting the transfer of the Common Stock.

(f)  Withholding Obligations.  To the extent provided by the terms of a Stock
     Award Agreement, the Participant may satisfy any federal, state or local
     tax withholding obligation relating to the exercise or acquisition of
     Common Stock under a Stock Award by any of the following means (in addition
     to the Company's right to withhold from any compensation paid to the
     Participant by the Company) or by a combination of such means:  (i)
     tendering a cash payment; (ii) authorizing the Company to withhold shares
     of Common Stock from the shares of Common Stock otherwise issuable to the
     Participant as a result of the exercise or acquisition of Common Stock
     under the Stock Award, provided, however, that no shares of Common Stock
     are withheld with a value exceeding the minimum amount of tax required to
     be withheld by law; or (iii) delivering to the Company owned and
     unencumbered shares of Common Stock.

12.  Adjustments upon Changes in Stock.

     The provisions in this Section 12 may be modified by the Board, Committee
or the person or persons delegated the authority to make Stock Awards under
Section 3 with respect to a particular Stock Award as provided in the pertinent
Stock Award Agreement.

(a)  Capitalization Adjustments.  If any change is made in the stock subject to
     the Plan, or subject to any Stock Award, without the receipt of
     consideration by the Company (through merger, consolidation,
     reorganization, recapitalization, reincorporation, stock dividend,

                                       15
<PAGE>

     dividend in property other than cash, stock split, liquidating dividend,
     combination of shares, exchange of shares, change in corporate structure or
     other transaction not involving the receipt of consideration by the
     Company), the Plan will be appropriately adjusted in the class(es) and
     maximum number of securities subject to the Plan pursuant to subsection
     4(a) and the maximum number of securities subject to award to any person
     pursuant to subsection 5(c), and the outstanding Stock Awards will be
     appropriately adjusted in the class(es) and number of securities and price
     per share of stock subject to such outstanding Stock Awards. The Board
     shall make such adjustments, and its determination shall be final, binding
     and conclusive. (The conversion of any convertible securities of the
     Company shall not be treated as a transaction "without receipt of
     consideration" by the Company.)

(b)  Dissolution or Liquidation.  In the event of a dissolution or liquidation
     of the Company, then all outstanding Stock Awards shall terminate
     immediately prior to such event.

(c)  Asset Sale, Merger, Consolidation or Reverse Merger.

     (i)   In the event of a "Change of Control" (as defined below), the
           surviving corporation or acquiring corporation shall assume any Stock
           Awards outstanding under the Plan or shall substitute similar stock
           awards (including an award to acquire the same consideration paid to
           the stockholders in the transaction constituting a "Change of
           Control" for those outstanding under the Plan). In the event such
           surviving corporation or acquiring corporation in the "Change of
           Control" refuses to assume such Stock Awards or to substitute similar
           stock awards for those outstanding under the Plan, then with respect
           to Stock Awards held by Participants whose Continuous Service has not
           terminated, the vesting of such Stock Awards (and, if applicable, the
           time during which such Stock Awards may be exercised) shall be
           accelerated in full, and the Stock Awards shall terminate if not
           exercised (if applicable) at or prior to such event. With respect to
           any other Stock Awards outstanding under the Plan, such Stock Awards
           shall terminate if not exercised (if applicable) prior to such event

     (ii)  If within twelve (12) months following the effective date of a
           "Change of Control," the employment of a Participant is terminated
           without Cause, then with respect to Stock Awards held by Participants
           whose Continuous Service was not terminated prior to the effective
           date of the "Change of Control," the vesting of such Stock Awards
           (and, if applicable, the time during which such Stock Awards may be
           exercised) shall be accelerated in full, and the Stock Awards shall
           be exercisable as provided in this Plan or the Participant's Stock
           Award Agreement.

     (iii) For purposes of this Section 12(c), a "Change of Control" shall mean
           any one of the following transactions or events: the following
           transactions ((i) a dissolution or liquidation of the Company; (ii) a
           sale of all or substantially all of the assets of the Company; (iii)
           a merger or consolidation in which the Company is not the surviving
           corporation and in which beneficial ownership of securities of the
           Company representing at least fifty percent (50%) of the combined
           voting power entitled to vote in the election of Directors has
           changed; (iv) a reverse merger in which the Company is the surviving
           corporation but the shares of Common Stock outstanding immediately
           preceding the merger are converted by virtue of the merger into other
           property, whether in the form of securities, cash or otherwise, and
           in which beneficial ownership of securities of the Company
           representing at least fifty percent (50%) of the

                                       16
<PAGE>

           combined voting power entitled to vote in the election of Directors
           has changed; (v) an acquisition by any person, entity or group within
           the meaning of Section 13(d) or 14(d) of the Exchange Act, or any
           comparable successor provisions (excluding any employee benefit plan,
           or related trust, sponsored or maintained by the Company or
           subsidiary of the Company or other entity controlled by the Company)
           of the beneficial ownership (within the meaning of Rule 13d-3
           promulgated under the Exchange Act, or comparable successor rule) of
           securities of the Company representing at least fifty percent (50%)
           of the combined voting power entitled to vote in the election of
           Directors; or (vi) in the event that the individuals who, as of the
           Listing Date, are members of the Company's Board (the "Incumbent
           Board"), cease for any reason to constitute at least fifty percent
           (50%) of the Board. If the election, or nomination for election by
           the Company's stockholders, of any new Director is approved by a vote
           of at least fifty percent (50%) of the Incumbent Board, such new
           Director shall be considered to be a member of the Incumbent Board in
           the future. Notwithstanding the foregoing, the initial public
           offering of the common stock of the Company shall not constitute a
           Change of Control.

13.  Amendment of the Plan and Stock Awards.

(a)  Amendment of Plan.  The Board at any time, and from time to time, may amend
     the Plan.  However, except as provided in Section 12 relating to

     thereunder relating to Incentive Stock Options and/or to bring the Plan
     and/or Incentive Stock Options granted under it into compliance therewith.

(d)  No Impairment of Rights.  Rights under any Stock Award granted before

     Participant consents in writing.

(e)  Amendment of Stock Awards.  The Board at any time, and from time to time,
     may amend the terms of any one or more Stock Awards; provided, however,

     amendment unless (i) the Company requests the consent of the Participant
     and (ii) the Participant consents in writing.

14.  Termination or Suspension of the Plan.

     the Company, whichever is earlier. No Stock Awards may be granted under the
     Plan while the Plan is suspended or after it is terminated.

(b)  No Impairment of Rights.  Suspension or termination of the Plan shall not
     impair rights and obligations under any Stock Award granted while the Plan
     is in effect except with the written consent of the Participant.

     The Plan shall become effective as determined by the Board, but no Stock
Award shall be exercised (or, in the case of a stock bonus, shall be granted)
unless and until the Plan has been approved by the Stockholders of the Company,
which approval shall be within twelve (12) months before or after the date the
Plan is adopted by the Board.

16.  Choice of Law.

construction, validity and interpretation of this Plan, without regard to such
state's conflict of laws rules.

     (a)   Administration by Board. The Board shall administer the Plan unless
and until the Board delegates administration to a Committee, as provided in
subsection 3(c).

     (b)   Powers of Board. The Board shall have the power, subject to, and

          (i)   General.  The Board may delegate administration of the Plan to a
Committee or Committees of one or more members of the Board, and the term

the administrative powers the Committee is authorized to exercise (and
references in this Plan to the Board shall thereafter be to the Committee or

provisions of the Plan, as may be adopted from time to time by the Board.  The
Board may abolish the Committee at any time and revest in the Board the
administration of the Plan.

          (ii)   Committee Composition when Common Stock is Publicly Traded. At
such time as the Common Stock is publicly traded, in the discretion of the
Board, a Committee may consist solely of two or more Outside Directors, in
accordance with Section 162(m) of the Code, and/or solely of two or more Non-
Employee Directors, in accordance with Rule 16b-3. Within the scope of such

more members of the Board who are not Outside Directors, the authority to grant
Stock Awards to eligible persons who are either (a) not then Covered Employees
and are not expected to be Covered Employees at the time of recognition of
income resulting from such Stock Award or (b) not persons with respect to whom
the Company wishes to comply with Section 162(m) of the Code and/or (2) delegate
to a committee of one or more members of the Board who are not Non-Employee
Directors the authority to grant Stock Awards to eligible persons who are not
then subject to Section 16 of the Exchange Act.

adjustments upon changes in stock, the stock that may be issued pursuant to
Stock Awards shall not exceed in the aggregate seven million four hundred
thousand (7,400,000) shares of non-voting Common Stock.

     (b)  Reversion of Shares to the Share Reserve.  If any Option shall for any
reason expire or otherwise terminate, in whole or in part, without having been
exercised in full, the stock not acquired under such Option shall revert to and
again become available for issuance under the Plan.  Shares subject to stock
appreciation rights exercised in accordance with the Plan shall not be available
for subsequent issuance under the Plan.

     (c)  Source of Shares. The stock subject to the Plan may be unissued shares
or reacquired shares, bought on the market or otherwise.

5.   Eligibility.

     (a)  Eligibility for Specific Stock Awards.  Incentive Stock Options may be
granted only to Employees.  Stock Awards other than Incentive Stock Options may
be granted to Employees, Directors and Consultants.

     (b)  Ten Percent Stockholders. No Ten Percent Stockholder shall be eligible
for the grant of an Incentive Stock Option unless the exercise price of such
Option is at least one hundred ten percent (110%) of the Fair Market Value of
the Common Stock at the date of grant and the Option is not exercisable after
the expiration of five (5) years from the date of grant.

     (c)  Section 162(m) Limitation.  Subject to the provisions of Section 11
relating to adjustments upon changes in stock, no employee shall be eligible to
be granted Stock Awards covering more than one million seven hundred fifty
thousand (1,750,000) shares of the Common Stock during any calendar year.  This
subsection 5(c) shall not apply prior to the Listing Date and, following the
Listing Date, this subsection 5(c) shall not apply until (i) the earliest of:
(1) the first material modification of the Plan (including any increase in the
number of shares reserved for issuance under the Plan in accordance with Section
4); (2) the issuance of all of the shares of Common Stock reserved for issuance
under the Plan; (3) the expiration of the Plan; or (4) the first meeting of
stockholders at which Directors of the Company are to be elected that occurs
after the close of the third calendar year following the calendar year in which
occurred the first registration of an equity security under Section 12 of the
Exchange Act; or (ii) such other date required by Section 162(m) of the Code and
the rules and regulations promulgated thereunder.

6.   Option Provisions.

     Each Option shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate.  All Options shall be separately
designated Incentive Stock Options or Nonstatutory Stock Options at the time of
grant, and a separate certificate or certificates will be issued for shares
purchased on exercise of each type of Option.  The provisions of separate
Options need not be identical, but each Option shall include (through
incorporation of provisions hereof by reference in the Option or otherwise) the
substance of each of the following provisions:

     (a)  Term. Subject to the provisions of subsection 5(b) regarding Ten
Percent Stockholders, no Incentive Stock Option shall be exercisable after the
expiration of ten (10) years from the date it was granted.

     (b)  Exercise Price of an Incentive Stock Option. Subject to the provisions
of subsection 5(b) regarding Ten Percent Stockholders, the exercise price of
each Incentive Stock Option shall be not less than one hundred percent (100%) of
the Fair Market Value of the stock subject to the Option on the date the Option
is granted. Notwithstanding the foregoing, an Incentive Stock Option may be
granted with an exercise price lower than that set forth in the preceding
sentence if such Option is granted pursuant to an assumption or substitution for
another option in a manner satisfying the provisions of Section 424(a) of the
Code.

                                       7.
<PAGE>

     (c)  Exercise Price of a Nonstatutory Stock Option. The exercise price of
each Nonstatutory Stock Option shall be not less than fifty percent (50%) of the
Fair Market Value of the stock subject to the Option on the date the Option is
granted. Notwithstanding the foregoing, a Nonstatutory Stock Option may be
granted with an exercise price lower than that set forth in the preceding
sentence if such Option is granted pursuant to an assumption or substitution for
another option in a manner satisfying the provisions of Section 424(a) of the
Code.

     (d)  Consideration. The purchase price of stock acquired pursuant to an
Option shall be paid, to the extent permitted by applicable statutes and
regulations, either (i) in cash at the time the Option is exercised or (ii) at
the discretion of the Board at the time of the grant of the Option (or
subsequently in the case of a Nonstatutory Stock Option) (1) by delivery to the
Company of other Common Stock, (2) according to a deferred payment or other
arrangement (which may include, without limiting the generality of the
foregoing, the use of other Common Stock) with the Participant or (3) in any
other form of legal consideration that may be acceptable to the Board; provided,
however, that at any time that the Company is incorporated in Delaware, payment
of the Common Stock's "par value," as defined in the Delaware General
Corporation Law, shall not be made by deferred payment.

     In the case of any deferred payment arrangement, interest shall be
compounded at least annually and shall be charged at the minimum rate of
interest necessary to avoid the treatment as interest, under any applicable
provisions of the Code, of any amounts other than amounts stated to be interest
under the deferred payment arrangement.

     (e)  Transferability of an Incentive Stock Option. An Incentive Stock
Option shall not be transferable except by will or by the laws of descent and
distribution and shall be exercisable during the lifetime of the Optionholder
only by the Optionholder. Notwithstanding the foregoing, the Optionholder may,
by delivering written notice to the Company, in a form satisfactory to the
Company, designate a third party who, in the event of the death of the
Optionholder, shall thereafter be entitled to exercise the Option.

     (f)  Transferability of a Nonstatutory Stock Option. A Nonstatutory Stock
Option shall be transferable to the extent provided in the Option Agreement. If
the Nonstatutory Stock Option does not provide for transferability, then the
Nonstatutory Stock Option shall not be transferable except by will or by the
laws of descent and distribution and shall be exercisable during the lifetime of
the Optionholder only by the Optionholder. Notwithstanding the foregoing, the
Optionholder may, by delivering written notice to the Company, in a form
satisfactory to the Company, designate a third party who, in the event of the
death of the Optionholder, shall thereafter be entitled to exercise the Option.

     (g)  Vesting Generally. The total number of shares of Common Stock subject
to an Option may, but need not, vest and therefore become exercisable in
periodic installments which may, but need not, be equal. The Option may be
subject to such other terms and conditions on the time or times when it may be
exercised (which may be based on performance or other criteria) as the Board may
deem appropriate. The vesting provisions of individual Options may vary. The
provisions of this subsection 6(g) are subject to any Option provisions
governing the minimum number of shares as to which an Option may be exercised.

                                       8.
<PAGE>

     (h)  Termination of Continuous Service. In the event an Optionholder's
Continuous Service terminates (other than upon the Optionholder's death or
Disability), the Optionholder may exercise his or her Option (to the extent that
the Optionholder was entitled to exercise it as of the date of termination) but
only within such period of time ending on the earlier of (i) the date three (3)
months following the termination of the Optionholder's Continuous Service (or
such longer or shorter period specified in the Option Agreement), or (ii) the
expiration of the term of the Option as set forth in the Option Agreement. If,
after termination, the Optionholder does not exercise his or her Option within
the time specified in the Option Agreement, the Option shall terminate.

     (i)  Extension of Termination Date.  An Optionholder's Option Agreement may
also provide that if the exercise of the Option following the termination of the
Optionholder's Continuous Service (other than upon the Optionholder's death or
Disability) would be prohibited at any time solely because the issuance of
shares would violate the registration requirements under the Securities Act,
then the Option shall terminate on the earlier of (i) the expiration of the term
of the Option set forth in subsection 6(a) or (ii) the expiration of a period of
three (3) months after the termination of the Optionholder's Continuous Service
during which the exercise of the Option would not be in violation of such
registration requirements.

     (j)  Disability of Optionholder.  In the event an Optionholder's Continuous
Service terminates as a result of the Optionholder's Disability, the
Optionholder may exercise his or her Option (to the extent that the Optionholder
was entitled to exercise it as of the date of termination), but only within such
period of time ending on the earlier of (i) the date twelve (12) months
following such termination (or such longer or shorter period specified in the
Option Agreement) or (ii) the expiration of the term of the Option as set forth
in the Option Agreement.  If, after termination, the Optionholder does not
exercise his or her Option within the time specified herein, the Option shall
terminate.

     (k)  Death of Optionholder.  In the event (i) an Optionholder's Continuous
Service terminates as a result of the Optionholder's death or (ii) the
Optionholder dies within the period (if any) specified in the Option Agreement
after the termination of the Optionholder's Continuous Service for a reason
other than death, then the Option may be exercised (to the extent the
Optionholder was entitled to exercise the Option as of the date of death) by the
Optionholder's estate, by a person who acquired the right to exercise the Option
by bequest or inheritance or by a person designated to exercise the option upon
the Optionholder's death pursuant to subsection 6(e) or 6(f), but only within
the period ending on the earlier of (1) the date eighteen (18) months following
the date of death (or such longer or shorter period specified in the Option
Agreement) or (2) the expiration of the term of such Option as set forth in the
Option Agreement.  If, after death, the Option is not exercised within the time
specified herein, the Option shall terminate.

     (l)  Early Exercise.  The Option may, but need not, include a provision
whereby the Optionholder may elect at any time before the Optionholder's
Continuous Service terminates to exercise the Option as to any part or all of
the shares subject to the Option prior to the full vesting of the Option. Any
unvested shares so purchased may be subject to an unvested share

                                       9.
<PAGE>

repurchase option in favor of the Company or to any other restriction the Board
determines to be appropriate.

     (m)  Right of Repurchase. The Option may, but need not, include a provision
whereby the Company may elect, prior to the Listing Date, to repurchase all or
any part of the vested shares acquired by the Optionholder pursuant to the
exercise of the Option.

     (n)  Right of First Refusal. The Option may, but need not, include a
provision whereby the Company may elect, prior to the Listing Date, to exercise
a right of first refusal following receipt of notice from the Optionholder of
the intent to transfer all or any part of the shares received upon the exercise
of the Option. Except as expressly provided in this subsection 6(n), such right
of first refusal shall otherwise comply with any applicable provisions of the
Bylaws of the Company.

     (o)  Re-Load Options. Without in any way limiting the authority of the
Board to make or not to make grants of Options hereunder, the Board shall have
the authority (but not an obligation) to include as part of any Option Agreement
a provision entitling the Optionholder to a further Option (a "Re-Load Option")
in the event the Optionholder exercises the Option evidenced by the Option
Agreement, in whole or in part, by surrendering other shares of Common Stock in
accordance with this Plan and the terms and conditions of the Option Agreement.
Any such Re-Load Option shall (i) provide for a number of shares equal to the
number of shares surrendered as part or all of the exercise price of such
Option; (ii) have an expiration date which is the same as the expiration date of
the Option the exercise of which gave rise to such Re-Load Option; and (iii)
have an exercise price which is equal to one hundred percent (100%) of the Fair
Market Value of the Common Stock subject to the Re-Load Option on the date of
exercise of the original Option. Notwithstanding the foregoing, a Re-Load Option
shall be subject to the same exercise price and term provisions heretofore
described for Options under the Plan.

          Any such Re-Load Option may be an Incentive Stock Option or a
Nonstatutory Stock Option, as the Board may designate at the time of the grant
of the original Option; provided, however, that the designation of any Re-Load
Option as an Incentive Stock Option shall be subject to the one hundred thousand
dollar ($100,000) annual limitation on the exercisability of Incentive Stock
Options described in subsection 10(d) and in Section 422(d) of the Code.  There
shall be no Re-Load Options on a Re-Load Option.  Any such Re-Load Option shall
be subject to the availability of sufficient shares under subsection 4(a) and
the "Section 162(m) Limitation" on the grants of Options under subsection 5(c)
and shall be subject to such other terms and conditions as the Board may
determine which are not inconsistent with the express provisions of the Plan
regarding the terms of Options.

7.   Provisions of Stock Awards other than Options.

     (a)  Stock Bonus Awards. Each stock bonus agreement shall be in such form
and shall contain such terms and conditions as the Board shall deem appropriate.
The terms and conditions of stock bonus agreements may change from time to time,
and the terms and conditions of separate stock bonus agreements need not be
identical, but each stock bonus

                                      10.
<PAGE>

agreement shall include (through incorporation of provisions hereof by reference
in the agreement or otherwise) the substance of each of the following
provisions:

          (i)   Consideration. A stock bonus shall be awarded in consideration
for past services actually rendered to the Company or an Affiliate for its
benefit.

          (ii)  Vesting.  Shares of Common Stock awarded under the stock bonus
agreement may, but need not, be subject to a share repurchase option in favor of
the Company in accordance with a vesting schedule to be determined by the Board.

          (iii) Termination of Participant's Continuous Service.  In the event a
Participant's Continuous Service terminates, the Company may reacquire any or
all of the shares of Common Stock held by the Participant which have not vested
as of the date of termination under the terms of the stock bonus agreement.

          (iv)  Transferability.  Rights to acquire shares under the stock bonus
agreement shall be transferable by the Participant only upon such terms and
conditions as are set forth in the stock bonus agreement, as the Board shall
determine in its discretion, so long as stock awarded under the stock bonus
agreement remains subject to the terms of the stock bonus agreement.

     (b)  Restricted Stock Awards. Each restricted stock purchase agreement
shall be in such form and shall contain such terms and conditions as the Board
shall deem appropriate. The terms and conditions of the restricted stock
purchase agreements may change from time to time, and the terms and conditions
of separate restricted stock purchase agreements need not be identical, but each
restricted stock purchase agreement shall include (through incorporation of
provisions hereof by reference in the agreement or otherwise) the substance of
each of the following provisions:

          (i)   Purchase Price.  The purchase price under each restricted stock
purchase agreement shall be such amount as the Board shall determine and
designate in such restricted stock purchase agreement.  The purchase price shall
not be less than eighty-five percent (85%) of the stock's Fair Market Value on
the date such award is made or at the time the purchase is consummated.

          (ii)  Consideration. The purchase price of stock acquired pursuant to
the restricted stock purchase agreement shall be paid either: (i) in cash at the
time of purchase; (ii) at the discretion of the Board, according to a deferred
payment or other arrangement with the Participant; or (iii) in any other form of
legal consideration that may be acceptable to the Board in its discretion;
provided, however, that at any time that the Company is incorporated in
Delaware, payment of the Common Stock's "par value," as defined in the Delaware
General Corporation Law, shall not be made by deferred payment.

          (iii) Vesting.  Shares of Common Stock acquired under the restricted
stock purchase agreement may, but need not, be subject to a share repurchase
option in favor of the Company in accordance with a vesting schedule to be
determined by the Board.

                                      11.
<PAGE>

          (iv) Termination of Participant's Continuous Service.  In the event a
Participant's Continuous Service terminates, the Company may repurchase or
otherwise reacquire any or all of the shares of Common Stock held by the
Participant which have not vested as of the date of termination under the terms
of the restricted stock purchase agreement.

          (v) Transferability. Rights to acquire shares under the restricted
stock purchase agreement shall be transferable by the Participant only upon such
terms and conditions as are set forth in the restricted stock purchase
agreement, as the Board shall determine in its discretion, so long as stock
awarded under the restricted stock purchase agreement remains subject to the
terms of the restricted stock purchase agreement.

     (c)  Stock Appreciation Rights.

          (i)  Authorized Rights. The following three types of stock
appreciation rights shall be authorized for issuance under the Plan:

               (1) Tandem Rights. A "Tandem Right" means a stock appreciation
right granted appurtenant to an Option which is subject to the same terms and
conditions applicable to the particular Option grant to which it pertains with
the following exceptions: The Tandem Right shall require the holder to elect
between the exercise of the underlying Option for shares of Common Stock and the
surrender, in whole or in part, of such Option for an appreciation distribution.
The appreciation distribution payable on the exercised the Tandem Right shall be
in cash (or, if so provided, in an equivalent number of shares of Common Stock
based on Fair Market Value on the date of the Option surrender) in an amount up
to the excess of (A) the Fair Market Value (on the date of the Option surrender)
of the number of shares of Common Stock covered by that portion of the
surrendered Option in which the Optionholder is vested over (B) the aggregate
exercise price payable for such vested shares.

               (2) Concurrent Rights. A "Concurrent Right" means a stock
appreciation right granted appurtenant to an Option which applies to all or a
portion of the shares of Common Stock subject to the underlying Option and which
is subject to the same terms and conditions applicable to the particular Option
grant to which it pertains with the following exceptions: A Concurrent Right
shall be exercised automatically at the same time the underlying Option is
exercised with respect to the particular shares of Common Stock to which the
Concurrent Right pertains. The appreciation distribution payable on an exercised
Concurrent Right shall be in cash (or, if so provided, in an equivalent number
of shares of Common Stock based on Fair Market Value on the date of the exercise
of the Concurrent Right) in an amount equal to such portion as determined by the
Board at the time of the grant of the excess of (A) the aggregate Fair Market
Value (on the date of the exercise of the Concurrent Right) of the vested shares
of Common Stock purchased -under the underlying Option which have Concurrent
Rights appurtenant to them over (B) the aggregate exercise price paid for such
shares.

               (3) Independent Rights.  An "Independent Right" means a stock
appreciation right granted independently of any Option but which is subject to
the same terms and conditions applicable to a Nonstatutory Stock Option with the
following exceptions:  An Independent Right shall be denominated in share
equivalents.  The appreciation distribution

                                      12.
<PAGE>

payable on the exercised Independent Right shall be not greater than an amount
equal to the excess of (a) the aggregate Fair Market Value (on the date of the
exercise of the Independent Right) of a number of shares of Company stock equal
to the number of share equivalents in which the holder is vested under such
Independent Right, and with respect to which the holder is exercising the
Independent Right on such date, over (b) the aggregate Fair Market Value (on the
date of the grant of the Independent Right) of such number of shares of Company
stock. The appreciation distribution payable on the exercised Independent Right
shall be in cash or, if so provided, in an equivalent number of shares of Common
Stock based on Fair Market Value on the date of the exercise of the Independent
Right.

          (ii)  Relationship to Options. Stock appreciation rights appurtenant
to Incentive Stock Options may be granted only to Employees. The "Section 162(m)
Limitation" provided in subsection 5(c) and any authority to reprice Options
shall apply as well to the grant of stock appreciation rights.

          (iii) Exercise.  To exercise any outstanding stock appreciation right,
the holder shall provide written notice of exercise to the Company in compliance
with the provisions of the Stock Award Agreement evidencing such right.   Except
as provided in subsection 5(c) regarding the "Section 162(m) Limitation," no
limitation shall exist on the aggregate amount of cash payments that the Company
may make under the Plan in connection with the exercise of a stock appreciation
right.

8.   Covenants of the Company.

     (a)  Availability of Shares. During the terms of the Stock Awards, the
Company shall keep available at all times the number of shares of Common Stock
required to satisfy such Stock Awards.

     (b)  Securities Law Compliance.  The Company shall seek to obtain from each
regulatory commission or agency having jurisdiction over the Plan such authority
as may be required to grant Stock Awards and to issue and sell shares of Common
Stock upon exercise of the Stock Awards; provided, however, that this
undertaking shall not require the Company to register under the Securities Act
the Plan, any Stock Award or any stock issued or issuable pursuant to any such
Stock Award.  If, after reasonable efforts, the Company is unable to obtain from
any such regulatory commission or agency the authority which counsel for the
Company deems necessary for the lawful issuance and sale of stock under the
Plan, the Company shall be relieved from any liability for failure to issue and
sell stock upon exercise of such Stock Awards unless and until such authority is
obtained.

9.   Use of Proceeds from Stock.

     Proceeds from the sale of stock pursuant to Stock Awards shall constitute
general funds of the Company.

                                      13.
<PAGE>

10.  Miscellaneous.

     (a) Acceleration of Exercisability and Vesting.  The Board shall have the
power to accelerate the time at which a Stock Award may first be exercised or
the time during which a Stock Award or any part thereof will vest in accordance
with the Plan, notwithstanding the provisions in the Stock Award stating the
time at which it may first be exercised or the time during which it will vest.

     (b) Stockholder Rights. No Participant shall be deemed to be the holder of,
or to have any of the rights of a holder with respect to, any shares subject to
such Stock Award unless and until such Participant has satisfied all
requirements for exercise of the Stock Award pursuant to its terms.

     (c) No Employment or other Service Rights.  Nothing in the Plan or any
instrument executed or Stock Award granted pursuant thereto shall confer upon
any Participant any right to continue to serve the Company or an Affiliate in
the capacity in effect at the time the Stock Award was granted or shall affect
the right of the Company or an Affiliate to terminate (i) the employment of an
Employee with or without notice and with or without cause, (ii) the service of a
Consultant pursuant to the terms of such Consultant's agreement with the Company
or an Affiliate or (iii) the service of a Director pursuant to the Bylaws of the
Company or an Affiliate, and any applicable provisions of the corporate law of
the state in which the Company or the Affiliate is incorporated, as the case may
be.

     (d) Incentive Stock Option $100,000 Limitation.  To the extent that the
aggregate Fair Market Value (determined at the time of grant) of stock with
respect to which Incentive Stock Options are exercisable for the first time by
any Optionholder during any calendar year (under all plans of the Company and
its Affiliates) exceeds one hundred thousand dollars ($100,000), the Options or
portions thereof which exceed such limit (according to the order in which they
were granted) shall be treated as Nonstatutory Stock Options.

     (e) Investment Assurances.  The Company may require a Participant, as a
condition of exercising or acquiring stock under any Stock Award, (i) to give
written assurances satisfactory to the Company as to the Participant's knowledge
and experience in financial and business matters and/or to employ a purchaser
representative reasonably satisfactory to the Company who is knowledgeable and
experienced in financial and business matters and that he or she is capable of
evaluating, alone or together with the purchaser representative, the merits and
risks of exercising the Stock Award; and (ii) to give written assurances
satisfactory to the Company stating that the Participant is acquiring the stock
subject to the Stock Award for the Participant's own account and not with any
present intention of selling or otherwise distributing the stock.  The foregoing
requirements, and any assurances given pursuant to such requirements, shall be
inoperative if (i) the issuance of the shares upon the exercise or acquisition
of stock under the Stock Award has been registered under a then currently
effective registration statement under the Securities Act or (ii) as to any
particular requirement, a determination is made by counsel for the Company that
such requirement need not be met in the circumstances under the then applicable
securities laws.  The Company may, upon advice of counsel to the Company, place
legends on stock certificates issued under the Plan as such counsel deems
necessary or

                                      14.
<PAGE>

appropriate in order to comply with applicable securities laws, including, but
not limited to, legends restricting the transfer of the stock.

     (f) Withholding Obligations. To the extent provided by the terms of a Stock
Award Agreement, the Participant may satisfy any federal, state or local tax
withholding obligation relating to the exercise or acquisition of stock under a
Stock Award by any of the following means (in addition to the Company's right to
withhold from any compensation paid to the Participant by the Company) or by a
combination of such means: (i) tendering a cash payment; (ii) authorizing the
Company to withhold shares from the shares of the Common Stock otherwise
issuable to the participant as a result of the exercise or acquisition of stock
under the Stock Award; or (iii) delivering to the Company owned and unencumbered
shares of the Common Stock.

11.  Adjustments upon Changes in Stock.

     (a) Capitalization Adjustments. If any change is made in the stock subject
to the Plan, or subject to any Stock Award, without the receipt of consideration
by the Company (through merger, consolidation, reorganization, recapitalization,
reincorporation, stock dividend, dividend in property other than cash, stock
split, liquidating dividend, combination of shares, exchange of shares, change
in corporate structure or other transaction not involving the receipt of
consideration by the Company), the Plan will be appropriately adjusted in the
class(es) and maximum number of securities subject to the Plan pursuant to
subsection 4(a) and the maximum number of securities subject to award to any
person pursuant to subsection 5(c), and the outstanding Stock Awards will be
appropriately adjusted in the class(es) and number of securities and price per
share of stock subject to such outstanding Stock Awards. The Board shall make
such adjustments, and its determination shall be final, binding and conclusive.
(The conversion of any convertible securities of the Company shall not be
treated as a transaction "without receipt of consideration" by the Company.)

     (b) Dissolution or Liquidation. In the event of a dissolution or
liquidation of the Company, then all outstanding Stock Awards shall terminate
immediately prior to such event.

     (c) Asset Sale, Merger, Consolidation or Reverse Merger. In the event of
(i) a sale of all or substantially all of the assets of the Company, (ii) a
merger or consolidation in which the Company is not the surviving corporation or
(iii) a reverse merger in which the Company is the surviving corporation but the
shares of Common Stock outstanding immediately preceding the merger are
converted by virtue of the merger into other property, whether in the form of
securities, cash or otherwise, then any surviving corporation or acquiring
corporation shall assume any Stock Awards outstanding under the Plan or shall
substitute similar stock awards (including an award to acquire the same
consideration paid to the stockholders in the transaction described in this
subsection 11(c) for those outstanding under the Plan). In the event any
surviving corporation or acquiring corporation refuses to assume such Stock
Awards or to substitute similar stock awards for those outstanding under the
Plan, then with respect to Stock Awards held by Participants whose Continuous
Service has not terminated, the vesting of such Stock Awards (and, if
applicable, the time during which such Stock Awards may be exercised) shall be
accelerated in full, and the Stock Awards shall terminate if not exercised (if
applicable)

                                      15.
<PAGE>

at or prior to such event. With respect to any other Stock Awards outstanding
under the Plan, such Stock Awards shall terminate if not exercised (if
applicable) prior to such event.

     (d) Special Acceleration Provisions. Notwithstanding any other provisions
of this Plan to the contrary, following the Listing Date if (i) a Change in
Control (as such term is defined below) occurs and (ii) within one (1) month
prior to the date of such Change in Control or thirteen (13) months after the
date of such Change in Control the Continuous Service of a Participant
terminates due to an involuntary termination (not including death or Disability)
without Cause or due to a Constructive Termination, then the vesting and
exercisability of all Stock Awards held by such Participant shall be accelerated
in full or any reacquisition or repurchase rights held by the Company with
respect to a Stock Award shall lapse in full, as appropriate; provided, however,
that if such potential acceleration of the vesting and exercisability of Stock
Awards (or lapse of reacquisition or repurchase rights held by the Company with
respect to Stock Awards) would cause a contemplated Change in Control
transaction that would otherwise be eligible to be accounted for as a "pooling-
of-interests" transaction to become ineligible for such accounting treatment
under generally accepted accounting principles as determined by the Accountants
prior to the Change of Control, such acceleration shall not occur.

     For purposes of this subsection 11(d) only, Change in Control means: (i) a
dissolution or liquidation of the Company; (ii) a sale of all or substantially
all of the assets of the Company; (iii) a merger or consolidation in which the
Company is not the surviving corporation and in which beneficial ownership of
securities of the Company representing at least fifty percent (50%) of the
combined voting power entitled to vote in the election of Directors has changed;
(iv) a reverse merger in which the Company is the surviving corporation but the
shares of Common Stock outstanding immediately preceding the merger are
converted by virtue of the merger into other property, whether in the form of
securities, cash or otherwise, and in which beneficial ownership of securities
of the Company representing at least fifty percent (50%) of the combined voting
power entitled to vote in the election of Directors has changed; (v) an
acquisition by any person, entity or group within the meaning of Section 13(d)
or 14(d) of the Exchange Act, or any comparable successor provisions (excluding
any employee benefit plan, or related trust, sponsored or maintained by the
Company or subsidiary of the Company or other entity controlled by the Company)
of the beneficial ownership (within the meaning of Rule 13d-3 promulgated under
the Exchange Act, or comparable successor rule) of securities of the Company
representing at least fifty percent (50%) of the combined voting power entitled
to vote in the election of Directors; or (vi) in the event that the individuals
who, as of the Listing Date, are members of the Company's Board  (the "Incumbent
Board"), cease for any reason to constitute at least fifty percent (50%) of the
Board.  (If the election, or nomination for election by the Company's
stockholders, of any new Director is approved by a vote of at least fifty
percent (50%) of the Incumbent Board, such new Director shall be considered to
be a member of the Incumbent Board in the future.)

     (e) Parachute Payments. In the event that the acceleration of the vesting
and exercisability of the Stock Awards or lapse of reacquisition or repurchase
rights held by the Company with respect to Stock Awards provided for in
subsection 11(d) and benefits otherwise

                                      16.
<PAGE>

payable to a Participant (i) constitute "parachute payments" within the meaning
of Section 280G (as it may be amended or replaced) of the Code, and (ii) but for
this subsection 11(e) would be subject to the excise tax imposed by Section 4999
(as it may be amended or replaced) of the Code (the "Excise Tax"), then such
Participant's benefits hereunder shall be delivered to such lesser extent which
would result in no portion of such benefits being subject to the Excise Tax;
provided, however, that the benefits hereunder shall be reduced only to the
extent necessary only after all cash amounts otherwise payable to such
Participant and which constitute "parachute payments" have been returned. Unless
the Company and such Participant otherwise agree in writing, any determination
required under this subsection 11(e) shall be made in writing in good faith by
the Accountants. For purposes of making the calculations required by this
subsection 11(e), the Accountants may make reasonable assumptions and
approximations concerning applicable taxes and may rely on reasonable, good
faith interpretations concerning the application of the Code. The Company and
such Participants shall furnish to the Accountants such information and
documents as the Accountants may reasonably request in order to make a
determination under this subsection 11(e). The Company shall bear all costs the
Accountants may reasonably incur in connection with any calculations
contemplated by this subsection 11(e).

12.  Amendment of the Plan and Stock Awards.

     (a) Amendment of Plan.  The Board at any time, and from time to time, may
amend the Plan.  However, except as provided in Section 11 relating to
adjustments upon changes in stock, no amendment shall be effective unless
approved by the stockholders of the Company to the extent stockholder approval
is necessary to satisfy the requirements of Section 422 of the Code, Rule 16b-3
or any Nasdaq or securities exchange listing requirements.

     (b) Stockholder Approval. The Board may, in its sole discretion, submit any
other amendment to the Plan for stockholder approval, including, but not limited
to, amendments to the Plan intended to satisfy the requirements of Section
162(m) of the Code and the regulations thereunder regarding the exclusion of
performance-based compensation from the limit on corporate deductibility of
compensation paid to certain executive officers.

     (c) Contemplated Amendments. It is expressly contemplated that the Board
may amend the Plan in any respect the Board deems necessary or advisable to
provide eligible Employees with the maximum benefits provided or to be provided
under the provisions of the Code and the regulations promulgated thereunder
relating to Incentive Stock Options and/or to bring the Plan and/or Incentive
Stock Options granted under it into compliance therewith.

     (d) No Impairment of Rights.  Rights under any Stock Award granted before
amendment of the Plan shall not be impaired by any amendment of the Plan unless
(i) the Company requests the consent of the Participant and (ii) the Participant
consents in writing.

     (e) Amendment of Stock Awards. The Board at any time, and from time to
time, may amend the terms of any one or more Stock Awards; provided, however,
that the rights under any Stock Award shall not be impaired by any such
amendment unless (i) the Company requests the consent of the Participant and
(ii) the Participant consents in writing.

                                      17.

13.  Termination or Suspension of the Plan.

     (a) Plan Term.  The Board may suspend or terminate the Plan at any time.
Unless sooner terminated, the Plan shall terminate on the day before the tenth
(10th) anniversary of the date the Plan is adopted by the Board or approved by
the stockholders of the Company, whichever is earlier.  No Stock Awards may be
granted under the Plan while the Plan is suspended or after it is terminated.

     (b) No Impairment of Rights. Suspension or termination of the Plan shall
not impair rights and obligations under any Stock Award granted while the Plan
is in effect except with the written consent of the Participant.

14.  Effective Date of Plan.

     The Plan shall become effective as determined by the Board, but no Stock
Award shall be exercised (or, in the case of a stock bonus, shall be granted)
unless and until the Plan has been approved by the stockholders of the Company,
which approval shall be within twelve (12) months before or after the date the
Plan is adopted by the Board.

15.  Choice of Law.

     All questions concerning the construction, validity and interpretation of
this Plan shall be governed by the law of the State of Delaware, without regard
to such state's conflict of laws rules.

                                      18.

3.   Administration.

Whether or not the Board has delegated administration, the Board shall have the
final power to determine all questions of policy and expediency that may arise
in the administration of the Plan.

     (b)  The Board (or the Committee) shall have the power, subject to, and
within the limitations of, the express provisions of the Plan:

          (i)   To determine when and how Rights to purchase shares of the

(which need not be identical).

          (ii)  To designate from time to time which Affiliates of the Company
shall be eligible to participate in the Plan.

          (iii) To construe and interpret the Plan and Rights granted under it,

The Board, in the exercise of this power, may correct any defect, omission or
inconsistency in the Plan, in a manner and to the extent it shall deem necessary
or expedient to make the Plan fully effective.

          (iv)  To amend the Plan as provided in paragraph 14.

          (v)   To terminate or suspend the Plan as provided in paragraph 16.

          (vi)  Generally, to exercise such powers and to perform such acts as

Committee may be, in the discretion of the Board, Non-Employee Directors and/or

shall have, in connection with the administration of the Plan, the powers
theretofore possessed by the Board, including the power to delegate to a

                                       3.
<PAGE>

subcommittee of two (2) or more Outside Directors any of the administrative
powers the Committee is authorized to exercise (and references in this Plan to
the Board shall thereafter be to the Committee or such a subcommittee), subject,
however, to such resolutions, not inconsistent with the provisions of the Plan,
as may be adopted from time to time by the Board. The Board may abolish the
Committee at any time and revest in the Board the administration of the Plan.

4.   Shares subject to the Plan.

     (a)  Subject to the provisions of paragraph 13 relating to adjustments upon
changes in securities, the shares of the Common Stock that may be sold pursuant
to Rights granted under the Plan shall not exceed in the aggregate two hundred
fifty thousand (250,000) shares of the Common Stock (the "Reserved Shares").  As
of each January 1, beginning on January 1, 2002, and continuing through and
including January 1, 2010, the number of Reserved Shares will be increased
automatically by the lesser of (i) one percent (1%) of the total number of
shares of the Common Stock outstanding on such January 1 or (ii) one hundred
twenty-five thousand (125,000) shares.  Notwithstanding the foregoing, the Board
may designate a smaller number of shares to be added to the share reserve as of
a particular January 1.  If any Right granted under the Plan shall for any
reason terminate without having been exercised, the shares of the Common Stock
not purchased under such Right shall again become available for the Plan.

     (b)  The shares of the Common Stock subject to the Plan may be unissued
shares of the Common Stock or shares of the Common Stock that have been bought
on the open market at prevailing market prices or otherwise.

5.   Grant of Rights; Offering.

     The Board may from time to time grant or provide for the grant of Rights to
purchase shares of the Common Stock under the Plan to Eligible Employees in an
Offering on an Offering Date or Dates selected by the Board.  Each Offering
shall be in such form and shall contain such terms and conditions as the Board
shall deem appropriate, which shall comply with the requirements of Section
423(b)(5) of the Code that all Employees granted Rights to purchase shares of
the Common Stock under the Plan shall have the same rights and privileges.  The
terms and conditions of an Offering shall be incorporated by reference into the
Plan and treated as part of the Plan.  The provisions of separate Offerings need
not be identical, but each Offering shall include (through incorporation of the
provisions of this Plan by reference in the document comprising the Offering or
otherwise) the period during which the Offering shall be effective, which period
shall not exceed twenty-seven (27) months beginning with the Offering Date, and
the substance of the provisions contained in paragraphs 6 through 9, inclusive.

6.   Eligibility.

     (a)  Rights may be granted only to Employees of the Company or, as the
Board may designate as provided in subparagraph 3(b), to Employees of an
Affiliate. Except as provided in subparagraph 6(b), an Employee shall not be
eligible to be granted Rights under the Plan unless, on the Offering Date, such
Employee has been in the employ of the Company or the Affiliate, as the case may
be, for such continuous period preceding such grant as the Board may require,
but

                                       4.
<PAGE>

in no event shall the required period of continuous employment be less than
ninety (90) days or equal to or greater than two (2) years; provided, however,
that Employees who are employed by the Company as of the Effective Date of this
Plan who would otherwise be Eligible Employees if not for the required period of
continuous employment with the Company shall be eligible to participate in the
Plan with respect to the first Offering Period without regard to their period of
prior continuous employment with the Company provided that they remain in
continuous employment through the end of the first Offering Period.

     (b)  The Board may provide that each person who, during the course of an
Offering, first becomes an Eligible Employee will, on a date or dates specified
in the Offering which coincides with the day on which such person becomes an
Eligible Employee or which occurs thereafter, receive a Right under that
Offering, which Right shall thereafter be deemed to be a part of that Offering.
Such Right shall have the same characteristics as any Rights originally granted
under that Offering, as described herein, except that:

          (i)   the date on which such Right is granted shall be the "Offering
Date" of such Right for all purposes, including determination of the exercise
price of such Right;

          (ii)  the period of the Offering with respect to such Right shall
begin on its Offering Date and end coincident with the end of such Offering; and

          (iii) the Board may provide that if such person first becomes an
Eligible Employee within a specified period of time before the end of the
Offering, he or she will not receive any Right under that Offering.

     (c)  No Employee shall be eligible for the grant of any Rights under the
Plan if, immediately after any such Rights are granted, such Employee owns stock
possessing five percent (5%) or more of the total combined voting power or value
of all classes of stock of the Company or of any Affiliate. For purposes of this
subparagraph 6(c), the rules of Section 424(d) of the Code shall apply in
determining the stock ownership of any Employee, and stock which such Employee
may purchase under all outstanding rights and options shall be treated as stock
owned by such Employee.

     (d)  An Eligible Employee may be granted Rights under the Plan only if such
Rights, together with any other Rights granted under all Employee Stock Purchase
Plans of the Company and any Affiliates, as specified by Section 423(b)(8) of
the Code, do not permit such Eligible Employee's rights to purchase shares of
the Common Stock or any Affiliate to accrue at a rate which exceeds twenty five
thousand dollars ($25,000) of the fair market value of such shares of the Common
Stock (determined at the time such Rights are granted) for each calendar year in
which such Rights are outstanding at any time.

     (e)  The Board may provide in an Offering that Employees who are highly
compensated Employees within the meaning of Section 423(b)(4)(D) of the Code
shall not be eligible to participate.

                                       5.

7.   Rights; Purchase Price.

     (a)  On each Offering Date, each Eligible Employee, pursuant to an Offering
made under the Plan, shall be granted the Right to purchase up to the number of
shares of the Common Stock purchasable either:

          (i)  with a percentage designated by the Board not exceeding fifteen
percent (15%) of such Employee's Earnings (as defined by the Board in each
Offering) during the period which begins on the Offering Date (or such later
date as the Board determines for a particular Offering) and ends on the date
stated in the Offering, which date shall be no later than the end of the
Offering; or

          (ii) with a maximum dollar amount designated by the Board that, as the
Board determines for a particular Offering, (1) shall be withheld, in whole or
in part, from such Employee's Earnings (as defined by the Board in each
Offering) during the period which begins on the Offering Date (or such later
date as the Board determines for a particular Offering) and ends on the date
stated in the Offering, which date shall be no later than the end of the
Offering and/or (2) shall be contributed, in whole or in part, by such Employee
during such period.

     (b)  The Board shall establish one or more Purchase Dates during an
Offering on which Rights granted under the Plan shall be exercised and purchases
of shares of the Common Stock carried out in accordance with such Offering.

     (c)  In connection with each Offering made under the Plan, the Board may
specify a maximum number of shares of the Common Stock that may be purchased by
any Participant as well as a maximum aggregate number of shares of the Common
Stock that may be purchased by all Participants pursuant to such Offering.  In
addition, in connection with each Offering that contains more than one Purchase
Date, the Board may specify a maximum aggregate number of shares of the Common
Stock which may be purchased by all Participants on any given Purchase Date
under the Offering.  If the aggregate purchase of shares of the Common Stock
upon exercise of Rights granted under the Offering would exceed any such maximum
aggregate amount, the Board shall make a pro rata allocation of the shares of
the Common Stock available in as nearly a uniform manner as shall be practicable
and as it shall deem to be equitable.

     (d)  The purchase price of shares of the Common Stock acquired pursuant to
Rights granted under the Plan shall be not less than the lesser of:

          (i)   an amount equal to eighty-five percent (85%) of the fair market
value of the shares of the Common Stock on the Offering Date; or

          (ii)  an amount equal to eighty-five percent (85%) of the fair market
value of the shares of the Common Stock on the Purchase Date.

8.   Participation; Withdrawal; Termination.

     (a)  An Eligible Employee may become a Participant in the Plan pursuant to
an Offering by delivering a participation agreement to the Company within the
time specified in the Offering, in such form as the Company provides. Each such
agreement shall authorize payroll

                                       6.
<PAGE>

deductions of up to the maximum percentage specified by the Board of such
Employee's Earnings during the Offering (as defined in each Offering). The
payroll deductions made for each Participant shall be credited to a bookkeeping
account for such Participant under the Plan and either may be deposited with the
general funds of the Company or may be deposited in a separate account in the
name of, and for the benefit of, such Participant with a financial institution
designated by the Company. To the extent provided in the Offering, a Participant
may reduce (including to zero) or increase such payroll deductions. To the
extent provided in the Offering, a Participant may begin such payroll deductions
after the beginning of the Offering. A Participant may make additional payments
into his or her account only if specifically provided for in the Offering and
only if the Participant has not already had the maximum permitted amount
withheld during the Offering.

     (b)  At any time during an Offering, a Participant may terminate his or her
payroll deductions under the Plan and withdraw from the Offering by delivering
to the Company a notice of withdrawal in such form as the Company provides.
Such withdrawal may be elected at any time prior to the end of the Offering
except as provided by the Board in the Offering.  Upon such withdrawal from the
Offering by a Participant, the Company shall distribute to such Participant all
of his or her accumulated payroll deductions (reduced to the extent, if any,
such deductions have been used to acquire shares of the Common Stock for the
Participant) under the Offering, without interest unless otherwise specified in
the Offering, and such Participant's interest in that Offering shall be
automatically terminated.  A Participant's withdrawal from an Offering will have
no effect upon such Participant's eligibility to participate in any other
Offerings under the Plan but such Participant will be required to deliver a new
participation agreement in order to participate in subsequent Offerings under
the Plan.

     (c)  Rights granted pursuant to any Offering under the Plan shall terminate
immediately upon cessation of any participating Employee's employment with the
Company or a designated Affiliate for any reason (subject to any post-employment
participation period required by law) or other lack of eligibility. The Company
shall distribute to such terminated Employee all of his or her accumulated
payroll deductions (reduced to the extent, if any, such deductions have been
used to acquire shares of the Common Stock for the terminated Employee) under
the Offering, without interest unless otherwise specified in the Offering. If
the accumulated payroll deductions have been deposited with the Company's
general funds, then the distribution shall be made from the general funds of the
Company, without interest.  If the accumulated payroll deductions have been
deposited in a separate account with a financial institution as provided in
subparagraph 8(a), then the distribution shall be made from the separate
account, without interest unless otherwise specified in the Offering.

     (d)  Rights granted under the Plan shall not be transferable by a
Participant otherwise than by will or the laws of descent and distribution, or
by a beneficiary designation as provided in paragraph 15 and, otherwise during
his or her lifetime, shall be exercisable only by the person to whom such Rights
are granted.

9.   Exercise.

     (a)  On each Purchase Date specified therefor in the relevant Offering,
each Participant's accumulated payroll deductions and other additional payments
specifically

                                       7.
<PAGE>

provided for in the Offering (without any increase for interest) will be applied
to the purchase of shares of the Common Stock up to the maximum number of shares
of the Common Stock permitted pursuant to the terms of the Plan and the
applicable Offering, at the purchase price specified in the Offering. No
fractional shares of the Common Stock shall be issued upon the exercise of
Rights granted under the Plan unless specifically provided for in the Offering.

     (b)  Unless otherwise specifically provided in the Offering, the amount, if
any, of accumulated payroll deductions remaining in any Participant's account
after the purchase of shares of the Common Stock that is equal to the amount
required to purchase one or more whole shares of the Common Stock on the final
Purchase Date of the Offering shall be distributed in full to the Participant at
the end of the Offering, without interest. If the accumulated payroll deductions
have been deposited with the Company's general funds, then the distribution
shall be made from the general funds of the Company, without interest. If the
accumulated payroll deductions have been deposited in a separate account with a
financial institution as provided in subparagraph 8(a), then the distribution
shall be made from the separate account, without interest unless otherwise
specified in the Offering. The amount of accumulated payroll deductions
remaining in any Participant's account that is less than the amount required to
purchase one whole share of Common Stock on the final Purchase Date of the
Offering shall be carried over to the next Offering or shall, if the Participant
requests or does not participate in the next Offering, be refunded.

     (c)  No Rights granted under the Plan may be exercised to any extent unless
the shares of the Common Stock to be issued upon such exercise under the Plan
(including Rights granted thereunder) are covered by an effective registration
statement pursuant to the Securities Act and the Plan is in material compliance
with all applicable state, foreign and other securities and other laws
applicable to the Plan. If on a Purchase Date in any Offering hereunder the Plan
is not so registered or in such compliance, no Rights granted under the Plan or
any Offering shall be exercised on such Purchase Date, and the Purchase Date
shall be delayed until the Plan is subject to such an effective registration
statement and such compliance, except that the Purchase Date shall not be
delayed more than twelve (12) months and the Purchase Date shall in no event be
more than twenty-seven (27) months from the Offering Date. If, on the Purchase
Date of any Offering hereunder, as delayed to the maximum extent permissible,
the Plan is not registered and in such compliance, no Rights granted under the
Plan or any Offering shall be exercised and all payroll deductions accumulated
during the Offering (reduced to the extent, if any, such deductions have been
used to acquire Shares) shall be distributed to the Participants, without
interest unless otherwise specified in the Offering. If the accumulated payroll
deductions have been deposited with the Company's general funds, then the
distribution shall be made from the general funds of the Company, without
interest. If the accumulated payroll deductions have been deposited in a
separate account with a financial institution as provided in subparagraph 8(a),
then the distribution shall be made from the separate account, without interest
unless otherwise specified in the Offering.

10.  Covenants of the Company.

     (a)  During the terms of the Rights granted under the Plan, the Company
shall ensure that the number of shares of the Common Stock required to satisfy
such Rights are available.

                                       8.
<PAGE>

     (b)  The Company shall seek to obtain from each federal, state, foreign or
other regulatory commission or agency having jurisdiction over the Plan such
authority as may be required to issue and sell shares of the Common Stock upon
exercise of the Rights granted under the Plan.  If, after reasonable efforts,
the Company is unable to obtain from any such regulatory commission or agency
the authority which counsel for the Company deems necessary for the lawful
issuance and sale of shares of the Common Stock under the Plan, the Company
shall be relieved from any liability for failure to issue and sell shares of the
Common Stock upon exercise of such Rights unless and until such authority is
obtained.

11.  Use of Proceeds from Shares.

     Proceeds from the sale of shares of the Common Stock pursuant to Rights
granted under the Plan shall constitute general funds of the Company.

12.  Rights as a Stockholder.

     A Participant shall not be deemed to be the holder of, or to have any of
the rights of a holder with respect to, shares of the Common Stock subject to
Rights granted under the Plan unless and until the Participant's shares of the
Common Stock acquired upon exercise of Rights under the Plan are recorded in the
books of the Company.

13.  Adjustments upon Changes in Securities.

     (a)  If any change is made in the shares of the Common Stock subject to the
Plan, or subject to any Right, without the receipt of consideration by the
Company (through merger, consolidation, reorganization, recapitalization,
reincorporation, stock dividend, dividend in property other than cash, stock
split, liquidating dividend, combination of shares, exchange of shares, change
in corporate structure or other transaction not involving the receipt of
consideration by the Company), the Plan will be appropriately adjusted in the
class(es) and maximum number of Reserved Shares of the Common Stock subject to
the Plan pursuant to subparagraph 4(a) including the annual increases in the
Reserved Shares of the Common Stock to be reserved under the Plan, and the
outstanding Rights will be appropriately adjusted in the class(es), number of
shares of the Common Stock and purchase limits of such outstanding Rights.  The
Board shall make such adjustments, and its determination shall be final, binding
and conclusive.  (The conversion of any convertible securities of the Company
shall not be treated as a transaction that does not involve the receipt of
consideration by the Company.)

     (b)  In the event of:  (i) a dissolution, liquidation, or sale of all or
substantially all of the assets of the Company; (ii) a merger or consolidation
in which the Company is not the surviving corporation; or (iii) a reverse merger
in which the Company is the surviving corporation but the shares of the Common
Stock outstanding immediately preceding the merger are converted by virtue of
the merger into other property, whether in the form of securities, cash or
otherwise, then: (1) any surviving or acquiring corporation may assume Rights
outstanding under the Plan or may substitute similar rights (including a right
to acquire the same consideration paid to the Company's stockholders in the
transaction described in this subparagraph 13(b)) for those outstanding under
the Plan, or (2) in the event any surviving or acquiring corporation does not
assume such Rights or substitute similar rights for those

                                       9.
<PAGE>

outstanding under the Plan, then, as determined by the Board in its sole
discretion, such Rights may continue in full force and effect or the
Participants' accumulated payroll deductions (exclusive of any accumulated
interest which cannot be applied toward the purchase of shares of the Common
Stock under the terms of the Offering) may be used to purchase shares of the
Common Stock immediately prior to the transaction described above under the
ongoing Offering and the Participants' Rights under the ongoing Offering
thereafter terminated.

14.  Amendment of the Plan.

     (a)  The Board at any time, and from time to time, may amend the Plan.
However, except as provided in paragraph 13 relating to adjustments upon changes
in securities and except as to minor amendments to benefit the administration of
the Plan, to take account of a change in legislation or to obtain or maintain
favorable tax, exchange control or regulatory treatment for Participants or the
Company or any Affiliate, no amendment shall be effective unless approved by the
stockholders of the Company to the extent stockholder approval is necessary for
the Plan to satisfy the requirements of Section 423 of the Code, Rule 16b-3
under the Exchange Act and any Nasdaq or other securities exchange listing
requirements.  Currently under the Code, stockholder approval within twelve (12)
months before or after the adoption of the amendment is required where the
amendment will:

          (i)   Increase the number of shares of the Common Stock reserved for
Rights under the Plan;

          (ii)  Modify the provisions as to eligibility for participation in the
Plan to the extent such modification requires stockholder approval in order for
the Plan to obtain employee stock purchase plan treatment under Section 423 of
the Code or to comply with the requirements of Rule 16b-3; or

          (iii) Modify the Plan in any other way if such modification requires
stockholder approval in order for the Plan to obtain employee stock purchase
plan treatment under Section 423 of the Code or to comply with the requirements
of Rule 16b-3.

     (b)  It is expressly contemplated that the Board may amend the Plan in any
respect the Board deems necessary or advisable to provide Employees with the
maximum benefits provided or to be provided under the provisions of the Code and
the regulations promulgated thereunder relating to Employee Stock Purchase Plans
and/or to bring the Plan and/or Rights granted under it into compliance
therewith.

     (c)  Rights and obligations under any Rights granted before amendment of
the Plan shall not be impaired by any amendment of the Plan, except with the
consent of the person to whom such Rights were granted, or except as necessary
to comply with any laws or governmental regulations, or except as necessary to
ensure that the Plan and/or Rights granted under the Plan comply with the
requirements of Section 423 of the Code.

15.  Designation of Beneficiary.

     (a)  A Participant may file a written designation of a beneficiary who is
to receive any shares of the Common Stock and/or cash, if any, from the
Participant's account under the Plan in

                                      10.
<PAGE>

the event of such Participant's death subsequent to the end of an Offering but
prior to delivery to the Participant of such shares of the Common Stock and
cash. In addition, a Participant may file a written designation of a beneficiary
who is to receive any cash from the Participant's account under the Plan in the
event of such Participant's death during an Offering.

     (b)  The Participant may change such designation of beneficiary at any time
by written notice. In the event of the death of a Participant and in the absence
of a beneficiary validly designated under the Plan who is living at the time of
such Participant's death, the Company shall deliver such shares of the Common
Stock and/or cash to the executor or administrator of the estate of the
Participant, or if no such executor or administrator has been appointed (to the
knowledge of the Company), the Company, in its sole discretion, may deliver such
shares of the Common Stock and/or cash to the spouse or to any one or more
dependents or relatives of the Participant, or if no spouse, dependent or
relative is known to the Company, then to such other person as the Company may
designate.

16.  Termination or Suspension of the Plan.

     (a)  The Board in its discretion may suspend or terminate the Plan at any
time. Unless sooner terminated, the Plan shall terminate at the time that all of
the shares of the Common Stock subject to the Plan's reserve, as increased
and/or adjusted from time to time, have been issued under the terms of the Plan.
No Rights may be granted under the Plan while the Plan is suspended or after it
is terminated.

     (b)  Rights and obligations under any Rights granted while the Plan is in
effect shall not be impaired by suspension or termination of the Plan, except as
expressly provided in the Plan or with the consent of the person to whom such
Rights were granted, or except as necessary to comply with any laws or
governmental regulation, or except as necessary to ensure that the Plan and/or
Rights granted under the Plan comply with the requirements of Section 423 of the
Code.

17.  Effective Date of Plan.

     The Plan shall become effective simultaneously with the effectiveness of
the Company's registration statement under the Securities Act with respect to
the initial public offering of shares of the Company's Common Stock (the
"Effective Date"), but no Rights granted under the Plan shall be exercised
unless and until the Plan has been approved by the stockholders of the Company
within twelve (12) months before or after the date the Plan is adopted by the
Board, which date may be prior to the Effective Date.

THIS SUBLEASE, dated December 3, 1999, between GMAC MORTGAGE CORPORATION, a

Sublessee,

                             W I T N E S S E T H:

Sublessor hereby lets to the Sublessee and Sublessee hires from the Sublessor
the following described premises:

     Approximately 2,912 rentable square feet known as Suite 100 located at
     110 - 110th Avenue, Bellevue, Washington,

to be used only for office purposes, for a term commencing December 1, 1999 (or
upon the date of first occupancy, whichever occurs later), and expiring May 31,
2000, at the yearly rent of EIGHTY-ONE THOUSAND FIVE HUNDRED THIRTY-SIX AND
04/100 DOLLARS ($81,536.04), payable in equal installments of $6,794.67 in
advance on the first business day of each and every month during the term,
together with monthly payments of $800.00 for furniture rental.

THE PARTIES HERETO COVENANT AND AGREE WITH EACH OTHER AS FOLLOWS:

FIRST - PAYMENT OF RENT: Sublessee shall pay the rent at the times and in the
manner aforesaid to General Motors Corporation, c/o Corporate Accounting, 4
Walnut Grove, Horsham, PA 19044, Attention: Leslie Kornfeld.

SECOND - REPAIRS: Sublessee at Sublessee's expense shall keep the premises in
good repair, ordinary wear and tear, repairs to the roof, exterior of the
building and structural repairs excepted, unless such repairs are made necessary
by the act or negligence of the Sublessee and at the expiration of the term to
remove its goods and effects and peaceably yield up the premises to the
Sublessor in as good condition as when delivered to Sublessee, ordinary wear and
tear, damage by fire, the elements, act of the public enemy or casualty
excepted; all notices to quit or vacate being hereby expressly waived, any law,
usage or custom to the contrary notwithstanding.

THIRD - COMPLIANCE WITH LAWS, ORDINANCES, AND ENVIRONMENTAL: Sublessee shall
promptly comply with all laws, ordinances, requirements, and regulations of the
federal, state, county, municipal, and other authorities, the fire insurance
underwriters, and any insurance organizations or associations; except that
Sublessee shall not be required to make any alterations to the exterior of the
building, or alterations of a structural nature. Sublessee represents and
warrants that it will comply with all specifically applicable Environmental Laws
in connection with its use of or operations at the property, and that Sublessee
warrants and agrees that it will indemnify and hold Sublessor harmless from any
claim to which Sublessor may be subjected to the extent such claim results from
Sublessee's breach of any of its representations or warranties.

FOURTH - VIEWING PREMISES: Sublessee shall use the premises exclusively for the
purpose set forth herein and during the last three (3) months of this Sublease,
or any extension thereof, and permit the Sublessor to display the usual "To Let"
signs and to show the premises to prospective tenants. Sublessee further agrees
that at any time during the term Sublessor, Sublessor's landlord, or their
agents, may enter the premises for the purpose of examining the condition
thereof, or to make repairs in any part of the building, but in making such
reservation, Sublessor does not assume any liability for the care or supervision
of the premises or appurtenances.

FIFTH - ALTERATIONS AND ASSIGNMENT: Sublessee will not make or permit to be made
any alterations or additions to said premises, nor assign, mortgage, or pledge
this Sublease, nor sublet the whole or any part of the premises without
Sublessor's written consent. Consent by Sublessor shall apply solely to the
particular transaction consented to and shall not constitute a waiver by
Sublessor of the provisions of this Sublease.

SIXTH - INSURANCE: Sublessee will not leave the premises unoccupied during the
term, nor by any act of commission or omission cause an increase in the rate of
insurance or the cancellation of any insurance policy. In the event of any
increase in the rate of insurance caused by Sublessee's occupancy, Sublessee
agrees to pay on demand the amount of any such increase, and in default of such
payment, such amount may be added to the next installment of rent as additional
rent. Sublessee shall, at its sole cost and expense, obtain and maintain during
the term of the Sublease, Comprehensive General Liability Insurance, including
Blanket Contractual Liability coverage, with limits of not less than Two Million
Dollars ($2,000,000) Combined Single Limit for Personal Injury and Property
Damage; Comprehensive Automobile Liability Insurance covering all owned, non-
owned and hired vehicles with limits of not less than One Million Dollars
($1,000,000) Combined Single Limit for Personal Injury and Property Damage; and
Statutory Workers Compensation and Employers Liability coverage with limits of
not less than $250,000. Sublessee shall deliver to Sublessor upon request a
certificate evidencing such coverages. Such insurance policies shall provide for
no cancellation or material alteration without thirty (30) days prior written
notice to Sublessor.

SEVENTH - SIGNS AND SIDEWALKS: Sublessee shall not install any awnings,
advertisements, or signs on any part of the premises without Sublessor's written
consent and will keep the sidewalks free from ice, snow, and all obstructions.

EIGHTH - UTILITIES: Sublessee will make its own arrangements for the supply and
payment of all services including without limitation gas, electricity, and
water.

NINTH - INDEMNIFICATION: Sublessor shall not be responsible for any defect or
change of condition in said premises, nor for any damage thereto, not to any
person, nor to goods or things contained therein due to any cause whatsoever
except the act or negligence of the Sublessor, and Sublessee will indemnify
Sublessor from any claims, demands, and actions arising in connection with
Sublessee's use of the property, or the use by any person occupying said
premises during the term hereof, or by reason of any breach or non-performance
of any covenant herein, or the violation of any law or regulation by Sublessee.

                                      1.
<PAGE>

TENTH - FIRE AND CASUALTY: If the premises shall be so damaged by fire, other
casualty, or act of the public enemy so as to be substantially destroyed, then
this Sublease shall terminate and any unearned rent paid in advance by Sublessee
shall be apportioned and refunded to it, but in case the premises are not
substantially destroyed, Sublessor will endeavor to have its Lessor restore the
premises and a just proportion of the rent shall abate according to the extent
to which premises have been rendered untenantable until the premises have been
restored. The Sublessee agrees to give the Sublessor immediate notice of any
damage to the premises.

ELEVENTH - DEFAULT: In the event Sublessee fails to perform or observe any of
the covenants contained herein on its part to be observed and performed for ten
(10) days after notice by Sublessor, (a) Sublessor may forthwith terminate or
cancel this Sublease by notifying Sublessee as hereinafter provided, and upon
such termination or cancellation, Sublessee shall be liable to Sublessor for all
damages Sublessor sustains by reason of Sublessee's breach of covenant and of
such termination or cancellation; or (b) Sublessor may forthwith re-enter the
premises without notice and upon re-entry may let the premises or any part
thereof as agent for Sublessee and receive the rent therefor, applying the same
first to the payment of such expense as Sublessor may be put to in entering and
letting the premises and then to the payment of the rent and the fulfillment of
Sublessee's covenants hereunder, and Sublessee agrees to pay and shall be liable
for amounts equal to the several installments of rent as they would, under the
terms of this Sublease, become due if no default had occurred, whether the
demised premises be re-let or remain vacant in whole or in part for a period
less than the remainder of the term, or for the whole thereof, but Sublessee
shall be entitled to be credited at the end of each month with any net amounts
actually received by Sublessor during such months for the use or occupancy of
the demised premises or any part thereof; provided, however, that all sums paid
and liabilities incurred by Sublessor for any of the purposes aforesaid (which
Sublessee also agrees to pay and shall be liable for) shall have been first paid
in full to Sublessor, either directly by Sublessee or out of moneys actually
received for renting said demised premises after Sublessor shall have received
undisputed possession thereof, and the maintenance of any action or proceeding
to recover possession of the premises or any installment or installments of rent
or any other moneys that may be due or become due from Sublessee to Sublessor
shall not preclude Sublessor from thereafter instituting and maintaining
subsequent actions or proceedings for the recovery of possession of the premises
or of any subsequent payment or payments of rent or any other moneys that may be
due or become due from Sublessee or Sublessor. A waiver by Sublessor of any
breach or breaches by Sublessee of any one or more of the covenants or
conditions hereof shall not bar forfeiture or any other rights or remedies of
Sublessor for any subsequent breach of any such or other covenants and
conditions.

TWELFTH - ADDITIONAL RENT: If Sublessor shall make any expenditure for which
Sublessee is responsible, or if Sublessee shall fail to make any payment which
Sublessee is obliged to make hereunder, then the amount thereof may, at
Sublessor's option, be added to any installment of rent then due or thereafter
becoming due.

THIRTEENTH - CONDEMNATION: In the event the premises or any part thereof are
taken or condemned for a temporary or permanent public or quasi-public use,
Sublessor may, at its option, terminate this Sublease and in such event any
unearned rent paid in advance shall be returned to Sublessee.

FOURTEENTH - DEMOLITION: If any authority having jurisdiction shall decide that
the building or buildings should be demolished and removed, then forthwith upon
such decision being made, the Sublessee shall vacate the premises and this
Sublease shall cease and come to an end and any unearned rent paid in advance by
Sublessee shall be apportioned and refunded to it.

FIFTEENTH - NOTICES: That all notices to be given hereunder by either party
shall be in writing and given by personal delivery to the Sublessee or to one of
the executive officers of the Sublessor or shall be sent by certified mail
addressed to the party intended to be notified at the post office address of
such party last known to the party giving such notice and notice given as
aforesaid shall be a sufficient service thereof. Provided, however, that it is
mutually agreed that the Sublessor appoints the General Director and all
Directors of Worldwide Real Estate, General Motors Corporation, Mail Code 482-
309-939, 485 West Milwaukee Avenue, Detroit, Michigan 48202, as its agents, and
that any of them may give or receive all notices to be given hereunder, and
notices shall be sent to any of them and not otherwise. The right is hereby
reserved by the Sublessor to countermand such appointments and make others
consistent herewith, due notice of which shall be given by the Sublessor to the
Sublessee.

SIXTEENTH - TERMINATION: If at any time proceedings in bankruptcy, or pursuant
to any other act for the relief of debtors, shall be instituted by or against
Sublessee, or if Sublessee shall compound Sublessee's debts or assign over
Sublessee's estate or effects for payment thereof, or if any execution shall
issue against Sublessee or any of Sublessee's effects whatsoever, or if a
receiver or trustee shall be appointed of Sublessee's property, or if this
Sublease shall by operation of law, devolve upon or pass to any person or
persons other than Sublessee personally, then and in each of said cases,
Sublessor may terminate this Sublease forthwith by notifying Sublessee as herein
provided. Upon such termination all sums due and payable or to become due and
payable by Sublessee shall at once become due and payable.

SEVENTEENTH - SUBLEASE: This is a Sublease and the Sublessor's interest in the
premises is as Lessee under an underlying Lease made by 110 Atrium Place
Associates, LLC, dated October 19, 1998, a copy of which, initialed for
identification, is attached hereto. This Sublease is expressly made subject to
all the terms and conditions of said underlying Lease and the Sublessee agrees
to use the premises in accordance with the terms of said underlying Lease and
not do or omit to do anything which will breach any of the terms thereof. If
said underlying Lease is terminated, this Sublease shall terminate
simultaneously and any unearned rent paid in advance shall be refunded to the
Sublessee.

EIGHTEENTH - QUIET POSSESSION: Sublessor hereby covenants that Sublessee, upon
paying the rent as herein reserved and performing all the covenants and
agreements herein contained on the part of the Sublessee, may quietly enjoy the
premises, except as herein otherwise provided, and subject, however, to the
terms of the Sublease to Sublessor, and to the terms of any mortgages which may
now or hereafter affect the premises.

NINETEENTH - WAIVER OF SUBROGATION: Sublessor and Sublessee waive all rights,
each against the other, for damages caused by fire or other perils covered by
insurance where such damages are sustained in connection with the occupancy of
the leased premises.

The covenants and agreements contained in the foregoing Sublease are binding
upon the parties hereto and their respective heirs, executors, administrators,
successors, legal representatives and assigns.

________________________________________________________________________________
                                  2. PREMISES
________________________________________________________________________________

     (a) Premises. Landlord hereby leases to Tenant and Tenant leases from
         --------
Landlord those certain premises described in subsection 1(a) and in Exhibit "A"
                                                                    -----------
attached hereto (the "Premises"); provided, that prior to the Second Floor
Commencement Date (defined below), the Premises shall include only the area
depicted on Exhibit "A" on the third floor of the Building (the "Third Floor").
            -----------
Immediately upon the Second Floor Commencement Date, and without any further
action of the parties, the Premises shall be automatically expanded to include
the area depicted on Exhibit "A" on the second floor of the Building (the
                     -----------
"Second Floor"). The exact amount of Rentable Square Feet and Useable Square
Feet in the Third Floor shall be determined upon the completion of the build-out
of the Tenant Improvements in and to the Third Floor pursuant to the Work Letter
Agreement attached hereto. The exact amount of Rentable Square Feet and Useable
Square Feet in the Second Floor shall be determined upon completion of the
build-out of the Tenant Improvements in and to the Second Floor pursuant to the
Work Letter Agreement attached hereto. All exact square footages of space in the
Premises, the Building, the Newport Corporate Center, or any portion thereof
shall be determined reasonably by Landlord's architect and verified by Tenant's
architect. Any dispute regarding any such determination shall be resolved in
accordance with Section 18(j). Until such determination of the exact number of
Rentable Square Feet and Useable Square Feet of space in the Premises, the
Building and the Newport Corporate Center as set forth above, the number of
Rentable Square Feet and Useable Square Feet of space shown in subsection 1(a)
shall control. Upon final determination of the number of Rentable Square Feet
and Useable Square Feet of space in the Second Floor or Third Floor, as the case
may be, the Building or the Newport Corporate Center, Landlord and Tenant shall,
within ten (10) days of Landlord's written request, execute a written
confirmation of Rentable Square Feet and Useable Square Feet in such floor
generally in the form attached hereto as "Exhibit D".  The "Rentable Square
                                         ----------
Feet" and "Useable Square Feet" as used in this Lease shall be calculated
according to the Building Owner's and Manager's Association ("1996 BOMA")
standard, the "Standard Method for Measuring Floor Area in Office Buildings -
American National Standard," ANSI Z65.1-1996.  The Premises are contained within
the building (the "Building") which is located at the address designated in
subsection 1(a).  The Building is located on the real property (the "Land")
described on Exhibit "B" attached hereto.  The term "Newport Corporate Center"
             -----------
shall mean the properties and buildings located thereon commonly known as One
Newport, Two Newport, Newport Tower, Newport Heights, Newport Terrace and Four
Newport described on Exhibit "B-1" attached hereto, together with such other
                     -------------
additional properties and/or buildings in the immediately adjacent area which
Landlord may add in the future, all of which Landlord may rename from time to
time. Tenant now consents to the addition of Five Newport to the Newport
Corporate Center at such time as Landlord so elects, provided it shall have been
completed.  "Tenant's Percentage of the Building" shall equal a fraction whose
numerator is the number of Rentable Square Feet within the Premises as set forth
in subsection 1(a) and whose denominator is the number of Rentable Square Feet
within the Building as set forth in subsection 1(a).  "Tenant's Percentage of
Newport Corporate Center" shall equal a fraction whose numerator is the number
of Rentable Square Feet within the Premises as set forth in subsection 1(a) and
whose denominator is the number of Rentable Square Feet within Newport Corporate
Center as set forth in subsection 1(a).  If the number of Rentable Square Feet
within the Premises, the Building or the Newport Corporate Center is adjusted,
including without limitation pursuant to the automatic expansion of the Premises
to include the Second Floor of the Building as provided in this subparagraph
1(a), then Tenant's Percentage of the Building and Tenant's Percentage of the
Newport Corporate Center shall be automatically adjusted without further action
of either party.  Upon the written request of either party, both parties shall
execute a written confirmation of such percentages generally in the form
attached hereto as "Exhibit D".

     (b)  Acceptance of Premises. All prior representations of Landlord and its
          ----------------------
agents with respect to the Premises or the Building are superceded by those
expressly set forth herein.  No rights, easements, or licenses are acquired by
Tenant by implication or otherwise except as expressly set forth in the
provisions of this Lease.  Tenant accepts the Premises "as is", subject to
Landlord's obligations under Exhibit "C", including without limitation
                             -----------
Landlord's obligation to construct any Tenant Improvements described in Exhibit
                                                                        -------
"C", and subject further to any latent defects in the Premises or Building which
- ---
are not reasonably ascertainable by a visual inspection of Tenant.  In addition,
Landlord shall deliver the Premises to Tenant with all cabling of prior tenants
removed (unless otherwise requested by Tenant).  The taking of possession of the
Premises by Tenant shall be conclusive evidence that the Premises and the
Building were in good condition and suitable for Tenant's intended use at the
time possession was taken, except for any latent defects in the Premises or
Building not reasonably ascertainable by a visual inspection of Tenant,
provided, however, Tenant agrees to provide Landlord notice promptly following
Tenant's discovery of any latent defects.

     (c)  Common Areas.  Tenant shall have the nonexclusive right to use in
          ------------
common with other tenants in the Building and in connection with Tenant's

          Landlord reserves the right from time to time without cost to Tenant
(except as allowed under the terms of this Lease) and unreasonable interference
with Tenant's use and, if Tenant's use of the Premises or Common Areas will be
interfered with, then upon reasonable prior written notice to Tenant

          v)    To install, use, maintain, repair and replace pipes, ducts,
conduits, wires and appurtenant meters and equipment for service to other parts
of the Building above the ceiling surfaces, below the floor surfaces, within the
walls and in the central core areas, and to relocate any pipes, ducts, conduits,
wires and appurtenant meters and equipment included in the Premises which are
located in the Premises or located elsewhere outside the Premises, and to expand
the Building;

          vi)   To make changes to the Common Areas, including, without
limitation, changes in the location, size, shape and number of driveways,
entrances, parking spaces (as long as the parking ratio for Tenant stated in
Section 1(g) is maintained unless a reduction on Landlord's overall parking
ratio for the Building is required by law), parking areas, loading and unloading
areas, ingress, egress, direction of traffic, landscaped areas and walkways;

          vii)  To close temporarily any of the Common Areas for maintenance

that Tenant shall notify Landlord if Tenant believes such maintenance is not
being diligently pursued to completion;

<PAGE>

          viii) To designate other land outside but adjacent to the boundaries
of the Building or Land to be a part of the Common Areas;

          ix)   To add additional buildings and improvements to the Common
Areas;

          x)    To use the Common Areas while engaged in making additional
improvements, repairs or alterations to the Building, or any portion thereof so
long as reasonable access to the Premises remains available;

          xi)   To do and perform such other acts and make such other changes
in, to or with respect to the Common Areas or the Building as Landlord may, in
the exercise of sound business judgment, deem to be appropriate; and

          xii)  To establish, modify or change reasonable rules governing the
move-in and move-out procedures of Tenant's furniture, equipment, and fixtures.

     (d)  Exclusive Option to Expand. Subject to the terms of this subsection
          --------------------------
2(d) and to the existing rights of the current tenant, Tenant shall have the
exclusive right to lease the approximately 23,529 rentable and 21,485 usable
square feet of space located on the first (1st) floor of the Building in the
location identified on Exhibit "A-1" attached hereto (the "Expansion Space").
                       -------------
Landlord shall notify Tenant in writing ("Landlord's Notice") of the estimated
date on which the Expansion Space will be available and delivered to Tenant for
installing Tenant's tenant improvements (the "Expansion Space Availability
Date"), which Landlord's Notice shall be provided to Tenant at least five (5)
months but not more than seven (7) months prior to the Expansion Space
Availability Date (unless Landlord and Tenant agree, in writing, to a different
notice period prior to the date Landlord's Notice is due).  Tenant shall have
twenty (20) business days from receipt of Landlord's Notice to notify Landlord
that Tenant elects to lease the Expansion Space.  If Tenant fails to notify
Landlord within such twenty (20) business day period that Tenant elects to lease
the Expansion Space, Tenant's rights hereunder to lease the Expansion Space
shall expire and Landlord shall be entitled to lease the Expansion Space to any
third party or third parties.  If Tenant notifies Landlord of Tenant's election
to lease the Expansion Space within such twenty (20) business day period, the
Expansion Space shall become part of the Premises and Tenant shall commence
paying Rent for such Expansion Space on the date which is the earlier of (1)
forty-five (45) days after Landlord actually tenders possession thereof to
Tenant for purposes of installing Tenant's tenant improvements, or (2) the date
Tenant opens for business in any part of the Expansion Space (the earlier of
which is hereafter referred to as the "Expansion Space Commencement Date").
Landlord estimates that the Expansion Space will be available for Lease to
Tenant sometime between November, 2000, and February, 2001.  Except as otherwise
provided in this Section 2(d), if Landlord is unable to deliver possession of
the Expansion Space as provided herein for any reason, Landlord shall not be
subject to any liability for the failure to deliver possession but in such event
Tenant shall not be liable for any Rent related to the Expansion Space until
Landlord tenders possession of the Expansion Space to Tenant.  No such failure
to deliver possession as provided herein shall in any other respect affect the
validity of this Lease or the obligation of Tenant hereunder; provided, however,
subject to delays caused by an event of force majeure (as defined in Section 31
and specifically including, without limitation, delays in Landlord's completion
of the Five Newport Building for reasons beyond the control of Landlord) or
delays caused by construction related changes requested by a tenant of the Five
Newport Building, if the Expansion Space is not available to Tenant to commence
construction of the Tenant Improvements on the date which is the earlier of (1)
within sixty (60) days after the Expansion Space Availability Date set forth in
Landlord's Notice, or (2) May 1, 2001 (regardless of whether or when Landlord's
Notice was given), and at such time Tenant does not sublease space from
Attachmate in the Four Newport Building, then per diem liquidated damages
payable by Landlord shall accrue in favor of Tenant in the amount of one day of
free Basic Rent with respect to the Expansion Space for each day which damages
shall continue until the actual Expansion Space Availability Date.
Notwithstanding anything in this Lease to the contrary, the parties agree that
the actual damages that Tenant would suffer as a consequence of a delay in the
delivery of the Expansion Space beyond the earlier of such dates are too
difficult to quantify.  Tenant shall have the right to offset any such accrued
liquidated damages against Basic Rent first due under this Lease with respect to
the Expansion Space. The Expansion Space Availability Date shall not be deemed
to have occurred until Tenant is actually given unencumbered access to the
Expansion Space to construct tenant improvements, or so long as any person or
entity claims a leasehold or other possessory interest in the Expansion Space.
Basic Rent for the Expansion Space shall be equal to the then current market
rate, which shall be determined in accordance with the procedures of Section
3(b)(iii) below and shall take into

                                       5
<PAGE>

consideration the Expansion Space Allowance (as defined below). Landlord shall
provide Tenant with a tenant improvement allowance with respect to the Expansion
Space in the amount of $12.00 per useable square foot multiplied by a fraction,
the denominator of which is sixty (60) and the numerator of which is the number
of months left in the initial Term at the time of the Expansion Space
Commencement Date (the "Expansion Space Allowance"). All tenant improvements to
the Expansion Space, as well as the disbursement of the Expansion Space
Allowance, shall be performed substantially in accordance with the Work Letter
Agreement attached hereto as Exhibit "C". Except as to any latent defects in the
                             -----------
Expansion Space which are not reasonably ascertainable by a visual inspection of
Tenant and subject to Landlord's obligations under Exhibit "C", Tenant shall
                                                   -----------
accept the Expansion Space in its "as is" condition as of the actual Expansion
Space Availability Date; provided, however, Tenant shall notify Landlord
promptly upon Tenant's discovery of any latent defects in the Expansion Space.
Beginning on the date Tenant notifies Landlord of its election to lease the
Expansion Space, Landlord and Tenant shall promptly and diligently work to amend
and supplement Exhibit "C" so as to conform it to include the Expansion Space
               -----------
and the necessary obligations and deadlines to be imposed on each party for
preparing the space plan, work schedule, construction documents and other steps
necessary to construct the Expansion Space to meet Tenant's requirements. The
parties agree to use the structure and process set forth in Exhibit "C" for
                                                            -----------
construction of the tenant improvements in the Expansion Space. The Expansion
Space shall be measured, and any disputes regarding such measurement shall be
resolved, as provided in Section 2(a) regarding the Third and Second Floors.
Notwithstanding anything contained above to the contrary, Tenant shall not be
entitled to exercise its option to lease the Expansion Space if, at the time of
such exercise, Tenant is in default under this Lease beyond any applicable cure
period. In addition, Tenant's exercise of its option with respect to the
Expansion Space shall, at Landlord's election, be void if Tenant is in default
under this Lease beyond any applicable cure period at any time after the date
Tenant exercises its option and prior to the commencement of Tenant's lease of
the Expansion Space. Within fifteen (15) days after Tenant notifies Landlord of
Tenant's election to lease the Expansion Space, Landlord and Tenant shall enter
into an amendment to this Lease adding the Expansion Space to the Premises upon
all terms and conditions of this Lease, which amendment shall include the
amended and supplemented Exhibit C. Except with respect to assignments of this
Lease to a Permitted Assignee (as defined in Section 10), this option to expand
is personal to Tenant and may not be exercised or be assigned, voluntarily or
involuntarily, by or to any person or entity other than Tenant and shall
automatically terminate upon the assignment or other transfer of Tenant's
interest in this Lease.

     (e) Right of First Offer.   Subject to the existing rights of existing
tenants in the Building or Newport Corporate Center, and provided that Tenant is
not in default under the terms and conditions of this Lease beyond any
applicable cure period at the time Tenant accepts the terms of a First Offer
Notice (defined below), Tenant shall have, during the initial Term, a one time
right of first offer to lease all space (other than the Premises) located in the
Building (the "First Offer Space"). Except as set forth in the following
sentence, at least sixty (60) days, but not more than one hundred twenty (120)
days, prior to offering any First Offer Space for lease in the market, Landlord
will provide Tenant with written notice (the "First Offer Notice") of the intent
to offer the First Offer Space for lease in the market, and shall offer to lease
the First Offer Space to Tenant on terms specified by Landlord in such First
Offer Notice, which terms Landlord shall represent are the then market terms for
a lease of the First Offer Space.  Notwithstanding the preceding sentence to the
contrary, Landlord shall not be required to give Tenant the First Offer Notice
at least sixty (60) days prior to offering any First Offer Space for lease in
the market (but Tenant shall still have five business days to respond to such
notice as described below) and Landlord may give Tenant such notice immediately
prior to offering the space for lease in the market if the First Offer Space
covered by such notice comes available for lease through a means other than the
natural expiration of an existing lease term. The First Offer Notice shall
specify: (i) the location and rentable area of the space which Landlord intends
to lease; (ii) the date upon which Landlord estimates such space shall be
available for occupancy; (iii) the annual rate of base rent per square foot of
rentable area which Landlord intends to charge for such space, including all
fixed and/or indexed adjustments to said rate; (iv) and all other economic terms
which Landlord intends to offer with respect to such space.  Such notice may
include terms that Landlord believes are market for various lease terms (e.g.,
the market terms for a three-year lease, a five-year lease, or a ten-year lease)
and may include terms that Landlord believes are market for various sized
premises (e.g. the market terms for a partial floor tenant or a full floor
tenant).  Tenant will then have five (5) business days from the date of the
First Offer Notice to express in writing an interest in leasing such space on
the terms offered and an additional twenty (20) days (after the expiration of
such initial five (5) day period) to complete a mutually acceptable amendment to
this Lease adding to the Premises the space which is the subject of the First
Offer Notice under the terms and conditions specified in the First Offer Notice.
If Tenant elects not to accept the

                                       6
<PAGE>

terms offered by Landlord, or if a mutually acceptable lease amendment is not
executed within the time limits set forth above, then Landlord may lease the
First Offer Space to another party or parties at final terms that are within
ninety-five percent (95%) of what Landlord offered to Tenant. Should Landlord
not complete a lease with another party within six (6) months after Tenant
rejects Landlord's offers, then Tenant's Right of First Offer will be renewed.
If Tenant leases the First Offer Space described in the First Offer Notice, then
Landlord shall tender such First Offer Space, as provided above, to Tenant in
its then "as is" condition (and otherwise in accordance with the terms of the
First Offer Notice), except for any latent defects not reasonably ascertainable
from a visual inspection by Tenant; provided, however, Tenant shall promptly
notify Landlord upon Tenant's discovery of any such latent defects. This Right
of First Offer is personal to Tenant and may not be exercised or be assigned,
voluntarily or involuntarily, by or to any person or entity other than Tenant or
any Permitted Assignee (as defined in Section 10) and shall automatically
terminate upon the assignment or other transfer of Tenant's interest in this
Lease.

                                    3. TERM
________________________________________________________________________________

     (a)  Term. The term of this Lease shall be for the period designated in
          -----
Section 1 above (the "Term") unless the Term shall be sooner terminated as
hereinafter provided.  The term "Term" shall include any exercised "Renewal
Term" (defined below).  The Term as well as the Tenant's obligation to pay Rent
(as defined in Section 5 below) with respect to the Premises (but excluding the
Second Floor) shall commence upon the date (the "Commencement Date") which is
the earlier of:

          i)   Substantial Completion (as defined in Exhibit "C") of the Tenant
                                                     -----------
Improvements described in the Work Letter Agreement for the portion of the
Premises located on the Third Floor, or

          ii)  The date that Tenant opened for business in any portion of the
Premises located on the Third Floor, or

          iii) Forty-five (45) days after the tender of possession of the
portion of the Premises located on the Third Floor to Tenant for the purposes of
commencing work on said Tenant Improvements (such date of tender of possession
being referred to as the "Third Floor Availability Date").

In the event the Commencement Date does not occur on the first day of the month,
Tenant shall pay Rent for the fractional month on a per diem basis (calculated
on the basis of a thirty-day month) until the first day of the following month.
The Term, as well as Tenant's obligation to pay Rent (as defined in Section 5
below) with respect to the Second Floor, shall commence upon the date (the
"Second Floor Commencement Date") which is the earlier of:

          iv)  Substantial Completion (as defined in Exhibit "C") of the Tenant
                                                     -----------
Improvements described in the Work Letter Agreement for the Second Floor, or

          v)   The date that Tenant opened for business in any portion of the
Second Floor, or

          vi)  Forty-five (45) days after the tender of possession of the Second
Floor to Tenant for the purpose of commencing work on said Tenant Improvements
(such date of tender of possession being referred to as the "Second Floor
Availability Date").

Except as provided below in Section 3(b), the Term shall terminate at midnight
on the last day of the sixtieth (60th) full month after the Second Floor
Commencement Date.  In the event the Second Floor Commencement Date does not
occur on the first day of the month, Tenant shall pay Rent for the Second Floor
for the fractional month on a per diem basis (calculated on the basis of a
thirty-day month) until the first day of the following month. Upon the
Commencement Date and the Second Floor Commencement Date, the parties shall
execute a written letter agreement setting forth the precise commencement and
termination dates of this Lease as of the execution date of said written letter
agreement.  Said letter agreement shall be generally in the form attached hereto
as Exhibit "D".  Failure to execute such letter agreement, however, shall not
   -----------
affect Tenant's liability hereunder.

                                       7
<PAGE>

     (b)  Option to Extend.
          ----------------

          i)   Landlord hereby grants Tenant the right and option to renew and
extend the Term of this Lease for two (2) consecutive periods of five (5) years
each (such renewal and extension periods are hereinafter referred to as a
"Renewal Term" or as the "First Renewal Term" and "Second Renewal Term", as
applicable) on the same terms and conditions contained in the Lease, except that

               a) Basic Rent for each Renewal Term shall be as set forth
hereinbelow,

               b) Except as expressly provided in this Section 3, Tenant shall
not be entitled to any lease concessions with respect to a Renewal Term
including, without limitation, commissions or allowances, free parking rights,
or storage space, and

               c) No additional options to renew and extend shall apply
following the expiration of the Second Renewal Term.

Written notice (the "Tenant's Election") of Tenant's exercise of its option to
renew and extend ("Option to Renew") the Term of this Lease for a Renewal Term
must be given to Landlord no less than ten (10) months prior to the date the
then current Term of the Lease would otherwise expire.  The Tenant's Election
shall be binding upon Tenant and shall set forth the name of the Landlord and
Tenant, the Lease date, and the Renewal Term dates.

          ii)  Notwithstanding anything to the contrary set forth in this
Section, at Landlord's option, Tenant shall not have the right to exercise an
Option to Renew:

               a) During the time commencing from the date Landlord gives to
Tenant a written notice that Tenant is in default under any provisions of this
Lease, and continuing until the default alleged in said notice is cured; or

               b) Under any of the following circumstances:

                  (1) If Tenant leases between three (3) to four (4) floors in
the Building at the time Tenant exercises its Option to Renew, Tenant does not
occupy at least two (2) of such floors or has entered into subleases for in
excess of 44,000 rentable square feet; or

                  (2) If Tenant leases less than three (3) floors but more than
one (1) floor in the Building at the time Tenant exercises its Option to Renew,
Tenant does not occupy at least one (1) of such floors or has entered into
subleases for in excess of 22,000 rentable square feet; or

                  (3) If Tenant leases one (1) floor in the Building or less,
Tenant shall not have the right to exercise a second Option to Renew.

          The period of time within which an Option to Renew may be exercised
shall not be extended or enlarged by reason of Tenant's inability to exercise an
Option to Renew because of the foregoing provisions and/or restrictions.  At
Landlord's election, all rights of Tenant under the provisions of this Option
shall terminate and be of no further force or effect even after Tenant's due and
timely exercise of the Option, if after such exercise, but prior to the
commencement date of the new term,

               c) Tenant fails to pay to Landlord a monetary obligation of
Tenant for a period of thirty (30) days after Tenant's receipt of written notice
from Landlord that such obligation is past due; or

               d) Tenant fails to commence to cure a default within thirty (30)
days after the date Landlord, during the term of this Lease, gives written
notice to Tenant of such default.

                                       8
<PAGE>

          Notwithstanding the above to the contrary, at Landlord's option, (1)
Tenant shall not be entitled to exercise an Option to Renew with respect to any
portion of the Premises in excess of 5,000 rentable square feet which is either
not occupied by Tenant or which is sublet to a third party on the date Tenant
otherwise attempts to exercise its Option to Renew, and (2) Tenant shall not
have the right to lease any portion of the Premises in excess of 5,000 square
feet with respect to which Tenant has already exercised an Option to Renew for a
Renewal Term if Tenant does not occupy such space on the Renewal Term
commencement date or has sublet such space to any third party on the Renewal
Term  commencement date.

          (iii) In the event Tenant validly exercises an Option to Renew the
Term of this Lease as herein provided, Basic Rent shall be adjusted as of the
commencement date of the applicable Renewal Term as follows:

                a) Commencing within ten (10) days after Landlord's receipt of
Tenant's Election, Landlord and Tenant shall attempt to agree upon Basic Rent
for the Premises for the applicable Renewal Term, such Basic Rent to equal the
estimated fair market rental value of the Premises for the applicable Renewal
Term.  If the parties are unable to agree upon the Basic Rent within thirty (30)
days after Landlord's receipt of Tenant's Election, then within thirty (30) days
thereafter each party, at its own cost and by giving written notice to the other
party, shall appoint a real estate appraiser with at least five (5) years full-
time commercial real estate appraisal experience in the area in which the
Premises are located to appraise and set Basic Rent for the applicable Renewal
Term.  If a party does not appoint an appraiser within ten (10) days after the
other party has given written notice of the name of its appraiser, the single
appraiser appointed shall be the sole appraiser and shall set Basic Rent for the
applicable Renewal Term.  If each party shall have so appointed an appraiser,
the two appraisers shall meet promptly and attempt to set the Basic Rent for the
applicable Renewal Term.  If the two appraisers are unable to agree within
thirty (30) days after the second appraiser has been appointed, they shall
attempt to select a third appraiser meeting the qualifications herein stated
within ten (10) days after the last day the two appraisers are given to set
Basic Rent.  If the two appraisers are unable to agree on the third appraiser
within such ten (10) day period, either of the parties to this Lease, by giving
five (5) days written notice to the other party, may apply to the then presiding
judge of the Superior Court of King County for the selection of a third
appraiser meeting the qualifications stated in this paragraph.  Each of the
parties shall bear one-half (1/2) of the cost of appointing the third appraiser
and of paying the third appraiser's fee.  The third appraiser, however selected,
shall be a person who has not previously acted in any capacity for either party.

                b) Within thirty (30) days after the selection of the third
appraiser, a majority of the appraisers shall set Basic Rent for the applicable
Renewal Term.  If a majority of the appraisers are unable to agree upon the
Basic Rent within the stipulated period of time, the three appraisals shall be
added together and their total divided by three (3).  The resulting quotient
shall be the Basic Rent for the Premises during the applicable Renewal Term.
If, however, the low appraisal and/or the high appraisal is/are more than five
percent (5%) lower and/or higher than the middle appraisal, the low appraisal
and/or the high appraisal shall be disregarded.  If only one (1) appraisal is
disregarded, the remaining two (2) appraisals shall be added together and their
total divided by two (2), and the resulting quotient shall be Basic Rent for the
Premises during the applicable Renewal Term.

                c) For purposes of determining the Basic Rent for a Renewal
Term, including the determination of Basic Rent by the appraisers, the "fair
market rental value" shall be based on the actual rental rates which ready and
willing tenants (including renewal tenants) are paying or would pay, as of the
applicable Renewal Term commencement date, as annual rent for a primary premises
(as distinguished from the rent payable for a sublet premises or with respect to
an assignment of an interest in an existing lease) to a ready and willing
landlord of such primary premises for space comparable to the amount then leased
by Tenant and comparable to the Premises, Building and Newport Corporate Center
in terms of quality, design, and location on the I-90 corridor; provided,
however, the "fair market rental value" shall not be increased as a result of
any special improvements Tenant has made at its expense and shall be determined
as if the Premises were improved with Landlord's Building standard tenant
improvements. Determination of fair market rental value will take into
consideration all relevant factors including, without limitation, any
concessions or inducements (e.g., rent abatement, tenant improvement and other
allowances) then being offered by landlords to prospective tenants, or then
being offered by tenants to landlords, for comparable space. Rental rates quoted
or used under sublease agreements shall be considered rates of special
circumstances and shall be excluded from the definition of "fair market rental
value" under this Section 3.

                                       9
<PAGE>

               d) If Landlord and Tenant are unable to agree upon the Basic Rent
for the Renewal Term prior to the commencement of such Renewal Term, Tenant
will, during such Renewal Term, pay Basic Rent at a rate equivalent to the Basic
Rent in effect immediately prior to the Renewal Term in question until the
parties agree upon the new Basic Rent, or until the Basic Rent is determined
pursuant to this Subsection. The amount of the new Basic Rent for the applicable
Renewal Term will be applied retroactively to the beginning of such Renewal
Term, and any rent adjustment will be made in connection with the next
installment of Basic Rent due, following the determination of Basic Rent
pursuant to this Subsection.

          (iv) The Option to Renew is granted for Tenant's or any Permitted
Assignee's personal benefit and may not be assigned or transferred by Tenant or
a Permitted Assignee, either voluntarily or by operation of law, in any manner
whatsoever, except to a Permitted Assignee.

          (v)  In the event Tenant timely and properly exercises an Option to
Renew, Landlord and Tenant shall within fifteen (15) days after the
determination of rent for the Renewal Term, execute an amendment to this Lease
extending the Lease Term on the terms and conditions set forth in this Section 3
and otherwise upon all terms and conditions of this Lease.

________________________________________________________________________________
                 4. DELIVERY OF PREMISES; DELAY IN POSSESSION
________________________________________________________________________________

     (a)  Third Floor.  Landlord shall tender possession of the Third Floor to
          -----------
Tenant for the purposes of commencing work on the Tenant Improvements related to
the Third Floor on the Third Floor Availability Date, which is estimated to be
on or after April 10, 2000, and Tenant shall not be obligated to accept
possession of the Third Floor prior to April 10, 2000.  The Third Floor
Availability Date shall not be deemed to have occurred until Tenant is actually
given unencumbered access to the Third Floor to construct tenant improvements
(regardless of whether or not Tenant has a tenant improvement permit).  Except
as otherwise provided in this Section 4(a), if Landlord is unable to deliver
possession of the Third Floor as provided herein for any reason, Landlord shall
not be subject to any liability for the failure to deliver possession but in
such event Tenant shall not be liable for any Rent until Landlord tenders
possession of the Third Floor to Tenant and the provisions of Section 3(a)
relating to the Third Floor have been satisfied.  No such failure to deliver
possession as provided herein shall in any other respect affect the validity of
this Lease or the obligation of Tenant hereunder; provided, however, subject to
delays caused by an event of force majeure (as described in Section 31) if the
Third Floor is not available to Tenant to commence construction of the Tenant
Improvements by July 15, 2000, Tenant shall thereafter have the right to
terminate this Lease by giving Landlord written notice of such termination on or
before July 24, 2000.  If Tenant elects to terminate this Lease, all Rent,
deposits and any other sums paid to Landlord by Tenant shall be refunded and
paid to Tenant within five (5) days of such termination.  Tenant shall have
access to the Third Floor at least two (2) weeks prior to Landlord's estimated
date of Substantial Completion of the Tenant Improvements on the Third Floor for
the purpose of installing Tenant's furniture, fixtures and equipment.

     (b)  Second Floor.  Landlord shall tender possession of the Second Floor to
          ------------
Tenant for the purposes of commencing work on the Tenant Improvements related to
the Second Floor on the Second Floor Availability Date, which shall be no sooner
than October 31, 2000 (unless otherwise agreed by Landlord and Tenant).  The
Second Floor Availability Date shall not be deemed to have occurred until Tenant
is actually given unencumbered access to the Second Floor to construct tenant
improvements (regardless of whether or not Tenant has a tenant improvement
permit).  Landlord shall use its best reasonable efforts provide Tenant with
five (5) months' prior written notice of the actual Second Floor Availability
Date, which Landlord currently estimates will be January 1, 2001.  Landlord
shall also provide Tenant with written notice of any change in the estimated
Second Floor Availability Date set forth in Section 1(b).  Except as otherwise
provided in this Section 4(b), if Landlord is unable to deliver possession of
the Second Floor as provided herein for any reason, Landlord shall not be
subject to any liability for the failure to deliver possession but in such event
Tenant shall not be liable for any Rent related to the Second Floor until
Landlord tenders possession of the Second Floor to Tenant and the provisions of
Section 3(a) relating to the Second Floor have been satisfied.  No such failure
to deliver possession as provided herein shall in any other respect affect the
validity of this Lease or the obligation of Tenant hereunder; provided, however,
subject to delays caused by an event of force majeure (as defined in Section 31
and specifically including, without limitation, delays in Landlord's completion
of the Five Newport

<PAGE>

Building for reasons beyond the control of Landlord) or delays caused by
construction related changes requested by a tenant of the Five Newport Building,
if the Second Floor is not available to Tenant to commence construction of the
Tenant Improvements by May 1, 2001, and at such time Tenant actually occupies
all of the Third Floor and all of the space Tenant subleases (if any) from
Attachmate in the Four Newport Building, then per diem liquidated damages
payable by Landlord shall accrue in favor of Tenant in the amount of one day of
free Basic Rent with respect to the Second Floor for each day which damages
shall continue until the actual Second Floor Availability Date. Notwithstanding
anything in this Lease to the contrary, the parties agree that the actual
damages that Tenant would suffer as a consequence of a delay in the delivery of
the Second Floor beyond May 1, 2001, are too difficult to quantify. Tenant shall
have the right to offset any such accrued liquidated damages against Basic Rent
first due under this Lease. Landlord's failure to provide the five (5) month's
prior written notice required under this Section 4(b) shall in no way alter,
modify or diminish the liquidated damage provisions of this Section 4(b). Tenant
shall have access to the Second Floor at least two (2) weeks prior to Landlord's
estimated date of Substantial Completion of the Tenant Improvements on the
Second Floor for the purpose of installing Tenant's furniture, fixtures and
equipment.

                                    5. RENT
________________________________________________________________________________

     (a) Monthly Basic Rent.  Tenant shall pay to Landlord as Basic Rent for the
         ------------------
Premises the sum set forth in subsection 1(c) (as may be adjusted through the
execution of Exhibit D), as applicable, which shall be payable in equal monthly
             ---------
installments.  The first installment (equal to the first month's Basic Rent)
shall be payable upon the execution of this Lease and the remaining installments
shall be paid, in advance, on the first day of each and every calendar month
during the Term.  Rent for any partial month shall be prorated based on the
actual number of days in such month.

     (b) Definition of Rent.  All amounts due from Tenant to Landlord under this
         ------------------
Lease other than Basic Rent shall be due as "Additional Rent".  The terms "Rent"
and "Rental" as used in this Lease shall mean all amounts to be paid hereunder
by Tenant whether those sums are designated as Basic Rent or Additional Rent or
otherwise and as adjusted by the terms of this Lease.  Failure by Tenant to pay
any sum of Rent due under this Lease shall entitle Landlord to pursue any or all
remedies specified in this Lease as well as remedies specified in RCW Chapter
59.12 or otherwise allowed by law.

     (c) Payment of Rent - No Deduction or Offset.  Tenant shall pay Rent to
         -----------------------------------------
Landlord, at the address of Landlord set forth in Section 1, without demand and
without deduction, setoff or counterclaim, except as otherwise provided in this
Lease.  If Landlord shall at any time or times accept Rent after it shall become
due and payable, such acceptance shall not excuse delay upon subsequent
occasions, or constitute, or be construed as a waiver of any or all of
Landlord's rights hereunder.  In addition to any late charges which may be
incurred under Section 22, Tenant shall pay interest at the rate of twelve
percent (12%) per annum compounded on all late payments of Rent thirty (30) or
more days past due.

                              6. OPERATING COSTS
________________________________________________________________________________

     (a) Acknowledged Net Terms.  Tenant acknowledges that this Lease is, in all
         -----------------------

<PAGE>

          xviii)    Costs incurred by the Landlord in leasing the Building,
including commissions, legal costs, advertising costs and tenant inducement
payments; and further provided that there shall be credited against Operating
Costs all net proceeds from policies of insurance, warranties or guarantees to
the extent (but only to the extent) that such proceeds reimburse the Landlord
for costs of repair and replacement which have previously been included in the
calculation of Operating Costs.

          If any facilities, services, systems or utilities:

          i)        For the operation, maintenance, administration, management,
repair or replacement of the Building and/or the Land are provided from another
building or buildings owned or operated by the Landlord or its agent; or

          ii)       For the operation, maintenance, administration, management,
repair or replacement of another building or buildings owned or operated by the
Landlord or its agent are provided from the Building and/or the Land, the costs,
charges and expenses therefor shall for the purpose of calculation of Operating
Costs be allocated by the Landlord between the Building and/or Land and the
other building or buildings on a reasonable basis.

          In computing Operating Costs for any fiscal period, if less than one
hundred percent (100%) of the Rentable Square Feet of the Building is occupied
by tenants during that period, then the variable Operating Costs for such year
shall be apportioned among the tenants as if the Building had been one hundred
percent (100%) occupied during such year by such Tenants.  For example, if there
were only two tenants occupying an equal amount of space in the Building during
one year, but they occupied less than the entire building, each tenant would pay
50% of the variable Operating Costs.

     (d)  Operating Cost and Adjustment.  Before the commencement of each
          ------------------------------
calendar year of the Term, or as soon thereafter as practicable, Landlord will
notify Tenant in writing of Landlord's estimate of Operating Costs, for the next
succeeding year (until the following December 31) and the amount of Tenant's
percentage share thereof as set forth in subsection 1(a).  Effective January 1
and each month thereafter, Tenant shall pay to Landlord as Additional Rent one-
twelfth (1/12) of Tenant's percentage share of said estimated Operating Costs.
On the next succeeding January 1, or as soon thereafter as possible or upon
sooner termination of the Term, Landlord will compute Tenant's percentage share
of the total Operating Costs for such previous year or portion thereof if
applicable, based on the actual Operating Costs and, shall provide Tenant with a
written statement showing the actual Operating Costs and Tenant's percentage
share of said costs. Landlord shall use its best efforts to deliver such
statement to Tenant by March 31.  Such statement shall provide an itemized
breakdown of the actual Operating Costs and shall be in generally the form
attached hereto as Exhibit "E".  If the total amount of Tenant's percentage
                   -----------
share of Operating Costs paid for such previous year or portion thereof is less
than Tenant's percentage share of actual Operating Costs, then Tenant shall pay
Landlord any deficiency.  If the total amount paid by Tenant for such previous
year or portion thereof exceeds the Tenant's percentage share of actual
Operating Costs, then Landlord shall credit such excess to the payment of Rent
which may thereafter become due.  Any adjustment payment required to be made
pursuant to this subsection 6(d) shall be made within thirty (30) days after
Landlord has notified Tenant thereof in writing. If this Lease commences at a
time other than at the commencement of a calendar year, or expires at a time
other than the expiration of the calendar year, Landlord shall estimate Tenant's
percentage share of Operating Costs for that portion of the calendar year
contained in the Term and Tenant shall pay such charge in equal monthly
installments on the first day of those months of that calendar year which are in
the Term.  If at any time Landlord obtains or receives additional information
regarding the actual amount of the Tenant's percentage share of Operating Costs,
Landlord may, at its election, adjust the amount of the monthly installments due
during the balance of the calendar year of the Term to reflect such additional
information.

     Even though the term has expired and Tenant has vacated the Premises, when
the final determination is made of Tenant's percentage share of Operating Costs
for the year in which this Lease terminates, Tenant shall pay within thirty (30)
days of written notice any increase due over the estimated expenses paid and,
conversely, if Tenant has otherwise complied with all other terms and conditions
of this Lease, Landlord shall refund any excess (any over-

                                      15
<PAGE>

payment in the event said expenses decrease) to Tenant within thirty (30) days
following the expiration or termination date of this Lease.

     (e)  Tenant's Right to Audit Operating Costs.
          ---------------------------------------

          (i)       Tenant shall have the right, upon fulfillment of the
conditions set forth below, to conduct one (1) audit of the Landlord's books and
records covering the Operating Costs for each particular calendar year, or
portion thereof as the case may be, to verify the accuracy of the Landlord's
determination of the Tenant's percentage of such Operating Costs. In the event
Tenant does not elect to conduct an audit of the Landlord's books and records
for a particular calendar year as set forth herein, then the Landlord's
statement of Operating Costs for that particular calendar year shall be deemed
conclusive and binding for all purposes. The conditions which must be met before
Tenant shall have the right to audit the books and records of a particular
calendar year are as follows:

                    a)  Tenant must provide Landlord not less than fifteen (15)
days' prior written notice of the Tenant's election to audit (the "Tenant's
Notice of Audit"); provided, however, Tenant's audit may only cover the
preceding two (2) calendar years.

                    b)  Tenant's audit must be undertaken and completed by
Tenant or its agents at reasonable times during Landlord's normal business hours
at the place where the Landlord's records are normally kept. Said audit must be
completed within ninety (90) days of Landlord's receipt of Tenant's Notice of
Audit.

                    c)  Tenant shall not be entitled to withhold Rent pending
the outcome of any audit.

                    d)  At the time the Tenant delivers its Tenant's Notice of
Audit to Landlord, the Tenant shall also provide evidence reasonably acceptable
to the Landlord that the audit will be a "fair and true audit." For the purposes
hereof, the term "fair and true audit" shall mean that the review of the subject
books and records shall be undertaken and completed by the Tenant, its officers
or employees, or by an independent accounting firm or property management firm
and that in no event will the party auditing the books (or that party's employer
or principal) directly or indirectly base the compensation or fees for such
audit work upon a percentage of the savings found or the return due the Tenant
by reason of that audit.

          (ii)      The Tenant's rights to audit the Landlord's books and
records shall be strictly limited to the right set forth above and the Tenant
shall have no right to audit any of the Landlord's books or records for any
calendar year before or after the Lease Term or for any calendar year other than
the immediately two (2) preceding calendar years as set forth above. All costs
and expenses of the audit shall be borne solely by the Tenant, except as set
forth below.

          (iii)     A true and correct copy of the audit shall be delivered to
the Landlord within fifteen (15) days of the completion of such audit. Any
underpayment shown by the Tenant's audit shall be paid in cash to Landlord
within thirty (30) days of the date of the audit. Any overpayment shown by such
audit shall be subject to the Landlord's prompt verification and, upon such
verification, shall be given to the Tenant in cash or as a credit against Rent
next falling due. If Landlord and Tenant are unable to agree upon any
adjustments Landlord or Tenant request as a result of an audit within thirty
(30) days after such request, the issues shall be resolved through binding
arbitration in Seattle, Washington, in accordance with the Commercial
Arbitration rules of the American Arbitration Association. If such audit
discloses an error in Landlord's determination of actual Operating Costs
allocable to the Premises in Landlord's favor in excess of five percent (5%) of
Tenant's percentage of actual annual Operating Costs (i.e., resulting in payment
or reimbursement by Landlord to Tenant), then all reasonable costs of Tenant's
audit shall be borne by Landlord.

                           7.      SECURITY DEPOSIT
________________________________________________________________________________

          Within thirty (30) days after the execution of this Lease, Tenant
shall deposit with Landlord a clean, irrevocable and unconditional standby
letter of credit in a form reasonably acceptable to Landlord and Tenant

                                      16
<PAGE>

(the "Letter of Credit") issued by a bank reasonably approved by Landlord
(hereinafter referred to as the "Bank") in favor of Landlord, in the amount of
One Million Dollars ($1,000,000.00). The Letter of Credit shall have a term
which expires no sooner than the date which is four (4) years from the
Commencement Date, or alternatively Tenant may deliver a one (1) year Letter of
Credit which by its terms automatically renews for successive one (1) year
periods until the date which is four (4) years from the Commencement Date unless
the Bank provides no less than thirty (30) days written notice to Landlord that
such Letter of Credit shall not be renewed. If the Bank provides Landlord
written notice that the Letter of Credit shall not be renewed, Landlord shall
have the right to draw down the entire amount of the Letter of Credit unless
Tenant substitutes, prior to the expiration of such Letter of Credit, a new
Letter of Credit which meets the requirements of this Section 7. If Tenant is
not in default of this Lease for the failure to pay Basic Rent beyond any
applicable cure period and has not previously been in default in the payment of
Basic Rent beyond any applicable cure period more than two (2) times in any
preceding twelve (12) month period on the date which is two (2) years from the
Commencement Date, then on such date or the immediately succeeding date on which
such conditions have been satisfied, (A) the amount of the Letter of Credit may,
in Tenant's sole discretion, be reduced to Five Hundred Thousand Dollars
($500,000.00), or (B) if the Bank has paid any sums to Landlord based upon the
Letter of Credit and Landlord still holds such sums or any portion thereof, then
Landlord shall return a portion of such sums to Tenant such that Landlord shall
retain only Five Hundred Thousand Dollars ($500,000.00). The Letter of Credit
shall be held by Landlord as security for the faithful performance and
observance by Tenant of the terms, conditions and provisions of this Lease. If
Tenant defaults in any of the terms, conditions or provisions of this Lease
including, but not limited to, the payment of Rent, and Tenant fails to cure any
such default after any required notice and within any applicable cure period
hereunder (i) Landlord shall have the right to require the Bank to make payment
to Landlord or its designee of the entire proceeds of the Letter of Credit, and
(ii) Landlord may, at the option of Landlord (but Landlord shall not be required
to) apply or retain the whole or any part of such sum so paid to it by Tenant or
the Bank to the extent required for the payment of any Rent or any other
reasonable sums incurred by Landlord as a result of such default, and (iii)
Landlord shall hold the remainder of such sum paid to it by the Bank or Tenant,
if any, for Landlord's benefit, as security for the faithful performance and
observance by Tenant of the terms, covenants, and conditions of this Lease on
Tenant's part to be observed and performed, with the same rights as hereinabove
set forth to apply or retain the same in the event of any further default by
Tenant under this Lease; provided that if Tenant, on its own accord at any time
thereafter or within ten (10) business days after written demand by Landlord,
shall deposit with Landlord or its designee the amount so applied or retained so
that Landlord or its designee shall have the full deposit on hand, then Landlord
shall immediately return the entire deposit to the Bank provided that the Bank
or such other Bank reasonably acceptable to Landlord issues, simultaneously with
Landlord's return of such deposit, a substitute letter of credit which meets the
requirements of this Section 7, which substitute letter of credit shall then be
the Letter of Credit. Tenant's failure to deposit with Landlord the amount so
applied or retained so that the Landlord or its designee shall have the full
deposit on hand within ten (10) business days of Landlord's written demand shall
constitute a breach of this Lease.

     In the event of a transfer, sale or lease of Landlord's interest in the
Building, Landlord shall transfer or cause to be transferred both the Letter of
Credit and any sums collected thereunder by Landlord, together with any other
sums then held by Landlord or its designee as such security, to the transferee,
and Landlord thereupon shall be released by Tenant from all liability under this
Section.  Tenant agrees to look solely to the new landlord for the return of the
Letter of Credit or any sums collected thereunder and any other security.
Tenant further covenants that it shall not assign or encumber, or attempt to
assign or encumber, any part of such security and that neither Landlord nor its
successors or assigns shall be bound by any such assignment, encumbrance,
attempted assignment, or attempted encumbrance.  Landlord shall not be required
to exhaust its remedies against Tenant before having recourse to the Letter of
Credit or such cash security held by Landlord.  Recourse by Landlord to the
Letter of Credit or such security shall not affect any remedies of Landlord
which are provided in this Lease or which are available to Landlord in law or
equity.

     In the event that Tenant is not in default of this Lease in the payment of
Basic Rent beyond any applicable cure period and has not previously been in
default in the payment of Basic Rent beyond any applicable cure period more than
two (2) times in any preceding twelve (12) month period on the date which is
four (4) years from the Commencement Date, then on such date, or the immediately
succeeding date on which such conditions have been satisfied, the Letter of
Credit or any sums held by Landlord as a result of a payment to Landlord by the
Bank under the Letter of Credit, except as the same may have been applied by
Landlord in accordance with this Lease, shall be

                                      17
<PAGE>

returned to Tenant; provided, however, Tenant shall have deposited with Landlord
on or before such date a cash security deposit in the amount of the last months'
Basic Rent, which shall be held by Landlord as a cash security deposit in lieu
of the Letter of Credit and Landlord and Tenant shall have the same rights and
obligations with respect thereto as they had with respect to the Letter of
Credit except that upon termination of this Lease Landlord shall refund or
credit to Tenant (or Tenant's successor) the unused portion of the cash security
deposit, provided that a reasonable amount of the deposit may be retained by
Landlord until Tenant has vacated the Premises and the final Operating Costs
reconciliation under Section 6 has been completed, at which time the balance
shall be promptly refunded to Tenant.

five (365) day per year access to the Building and Premises without prior notice

desired by Tenant shall be contracted for by Tenant directly with Landlord's
janitorial agent, and the cost and payment thereof shall be Tenant's
responsibility.

          (vi)      Provide water for drinking, lavatory and toilet purposes
drawn through fixtures installed by Landlord.

be in accordance with Section 8 of this Lease.

          (viii)    Utilities or services provided to Tenant in excess of the
services provided herein, or other than during the Building Business Hours
described herein, shall be charged to Tenant as Additional Rent at reasonable
rates established by Landlord as to services and as set forth in Section 8(a)ii)
as to utilities, and shall be payable monthly.

                                      18
<PAGE>

          (ix)      Except as provided in Section 9(p), Landlord shall, as of
the Commencement Date and throughout the entire term of this Lease, comply with
the provisions of the Americans with Disabilities Act ("ADA") as regards the
Building, Land and Common Areas. Landlord reserves the right to object to and
appeal any determination that it must take any specific action to comply with
the ADA; provided Landlord shall hold Tenant harmless from any adverse effects
or cost of such objection or appeal.

     (b)  Interruption.  It is understood that Landlord does not warrant that
          ------------
 any of the services referred to above will be free from interruption by virtue
 of a strike or a labor trouble or any other cause beyond Landlord's reasonable
 control. Except as otherwise provided in this Lease, such interruption of
 service shall not be deemed an eviction or disturbance of Tenant's use or
 possession of the Premises, or any part thereof, nor shall it render Landlord
 liable to Tenant for damages, by abatement or reduction of Rent or otherwise,
 nor shall it relieve Tenant from performance of Tenant's obligations under this
 Lease, nor shall Tenant be relieved from the performance of any covenant or
 agreement in this Lease because of such failure or interruption. Landlord
 reserves the right to stop service of the elevator, plumbing, ventilation, air-
 conditioning, and electrical systems, when necessary, by reason of accident or
 emergency, or for repairs, alterations or improvements, which are in the
 reasonable judgment of Landlord desirable or necessary, until said repairs,
 alterations or improvements shall have been completed; provided, Landlord shall
 use its good faith efforts to minimize interruption to Tenant's business
 operations.

     (c)  Self-Help Rights. If an interruption of services or utilities which is
          ----------------
caused by the intentional or negligent act or omission of Landlord materially
interferes with the conduct of Tenant's business in the Premises for three (3)
consecutive business days after notice thereof from Tenant to Landlord, Rent
shall be abated thereafter in proportion to the extent of the interference until
such services or utilities are restored and, if such services or utilities are
not restored within such three (3) day period, Tenant shall have the right,
after giving Landlord at least 24 hours prior written notice of the actions
Tenant proposes to take, to take such reasonable actions as may be necessary to
remedy the situation.  Landlord shall, within thirty (30) days of receipt of
evidence thereof, reimburse Tenant for Tenant's reasonable out-of-pocket costs
incurred in connection with Tenant's corrective actions taken pursuant to this
Section.

                            9.      CARE OF PREMISES
________________________________________________________________________________

     Tenant agrees that it shall:


     (a)  Not use or occupy the Premises in violation of law or of the
certificate of occupancy issued for the Building, and shall, upon written notice
from Landlord, discontinue any use of the Premises which is declared by any
governmental authority having jurisdiction to be a violation of law or of said
certificate of occupancy.  Tenant shall comply with any direction of any
governmental authority having jurisdiction which shall, by reason of the nature
of Tenant's use or occupancy of the Premises, impose any duty upon Tenant or
Landlord with respect to the Premises or with respect to the use or occupancy
thereof.

     (b)  Give Landlord access to the Premises at all reasonable times, without
charge or diminution of Rent, to enable Landlord to examine the same and to make
such repairs, additions and alterations as Landlord reasonably may deem
advisable, including, upon reasonable advance notice, the right to show the
Premises for the purpose of a potential sale or lease; provided, Landlord shall
only have the right to show the Premises to a prospective tenant during the last
ten (10)months of the Lease Term and, provided further, that any third party
which Landlord shows the Premises to shall be accompanied by a Tenant
representative and shall required to sign a non-disclosure agreement in a form
reasonably acceptable to Tenant prior to such third party entering Tenant's
server room or any other confidential areas.  If Landlord gives notice to Tenant
and Tenant fails to respond to Landlord within twenty-four (24) hours then
Landlord shall have the right to enter the Premises.

     (c)  At Tenant's own cost and expense and without liens, keep, repair,
maintain and replace the Premises, and every part thereof, including all
fixtures, equipment and Tenant Improvements, in first class order, condition and
repair and shall make all replacements necessary to keep the same in such
condition, ordinary wear and tear and damage caused by Landlord, casualty or
condemnation excepted; provided that Landlord shall keep, maintain, repair

                                      19
<PAGE>

and replace in good condition and repair (1) the structural elements of the
Building (including without limitation the foundations, exterior walls, roof and
roof membrane) and the gutters and downspouts of the Building, (2) the sewer,
water, gas, telephone and power lines and meters serving the Premises, and (3)
the plumbing, heating, ventilating, air conditioning, elevator and electrical
system installed or furnished by Landlord; provided further that Landlord shall
make such repairs to the Premises as may be required or become necessary because
of any latent defects not ascertainable from a visual inspection by Tenant
within a reasonable time after Landlord receives notice of such defects. If
Tenant shall fail to commence to so repair and maintain the Premises after five
(5) days notice from Landlord to do so (or such shorter period as Landlord, in
the exercise of its good faith business judgment, may decide that the
circumstances warrant), Landlord may, but in no event shall be obligated to,
make the repairs and Tenant shall pay the reasonable cost thereof to Landlord
within five (5) days after written demand as Additional Rent. Except to the
extent they are excluded from Operating Costs under Section 6, maintenance and
repair costs incurred by Landlord with respect to the structural elements of the
Building and the plumbing, heating, ventilating, air conditioning, elevator and
electrical system installed or furnished by Landlord shall be part of the
Operating Costs defined in Section 6; provided that, except to the extent
Landlord has waived its right of recovery against Tenant in Section 15, if such
maintenance and repairs are caused in part or in whole by the act, neglect, or
omission by Tenant, its agents, employees, sublessees, licensees, or invitees,
Tenant shall pay to Landlord, as Additional Rent, that portion of the cost of
such maintenance and repairs which, in Landlord's good faith business judgment,
is reasonably attributable to the act, neglect, or omission by Tenant, its
agents, employees, sublessees, licensees, or invitees.

     (d)  Recognize that improvements attached to the Premises (excluding all
property that shall remain the property of Tenant as provided in Section 25(c))
become the property of the Building and may not be removed without approval of
Landlord which approval shall not be unreasonably withheld, unreasonably
conditioned or unreasonably delayed, except that such approval may be subject to
the Tenant's paying for the cost of repairs resulting from the removal of such
improvements.

     (e)  Upon the termination of this Lease in any manner whatsoever, remove
Tenant's property and those of any other person claiming under Tenant, and quit
and deliver up the Premises to Landlord peaceably and quietly in as good order
and condition as the same is as of the Commencement Date (as to the Third Floor)
or as of the Second Floor Commencement Date (as of the Second Floor) or
hereafter may be put in by Landlord or Tenant, reasonable use,  wear and tear
thereof, damage by Landlord, casualty or condemnation, and permitted alterations
or improvements not required to be removed at the time of the installation of
the same as provided in Section 25(c) excepted.  Any and all reasonable costs
incurred by Landlord to restore the Premises to such good order and condition
will be billed to Tenant, and property not removed by Tenant at the termination
of this Lease, however terminated, shall be considered abandoned and Landlord
may dispose of the same as it deems expedient with reasonable cost thereof to be
billed to the Tenant.

     (f)  Except as may otherwise be provided in this Lease, not place signs on
the Premises except as authorized and approved by Landlord, such authorization
and approval not to be unreasonably withheld, unreasonably conditioned or
unreasonably delayed, and subject to all applicable governmental rules and
restrictions, as well as the "Building Rules and Regulations" as set forth in
Exhibit "F".
- -----------

     (g)  Except as expressly provided in this Lease, not make any alteration
of, improvements to, or addition to the Premises without the prior written
approval of Landlord, which approval shall not be unreasonably withheld,
unreasonably conditioned or unreasonably delayed; provided that Tenant shall
have the right to install an electronic security system within the Premises,
serving only the Premises, as its sole cost and expense, and Tenant shall, upon
the expiration or earlier termination of this Lease, remove such security system
and repair any damage caused by such removal and restore the portion of the
Premises affected thereby to its original condition as it existed as of the
Commencement Date.

     (h)  Not install or authorize the installation of more than six (6) coin
operated vending machines without obtaining prior written consent from Landlord,
which consent shall not be unreasonably withheld, unreasonably conditioned or
unreasonably delayed; provided, however, that Tenant shall obtain Landlord's
prior approval of the location of all vending machines and such machines shall
be located in an area with sufficient structural support.

                                      20
<PAGE>

     (i)  Not do or permit anything to be done in or about the Premises which
will in any way unreasonably obstruct or interfere with the rights of other
tenants or occupants of the Building, 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.  Tenant shall not
commit or suffer to be committed any waste in or upon the Premises.

     (j)  Not do or permit to be done anything which will invalidate or increase
the cost of any fire, extended coverage or any other insurance policy covering
the Building and/or property located therein, unless Tenant agrees, after
Landlord gives thirty (30) days' prior written notice to Tenant of the cost
thereof, to reimburse Landlord for any increase in the cost of such insurance
and subject to Landlord's lender's approval.  Tenant shall promptly, upon
demand, reimburse Landlord for any additional premium charges for such policy by
reason of Tenant's failure to comply with the provisions of this subsection
9(j).

     (k)  Observe the "Building Rules and Regulations" described in Exhibit "F",
                                                                    -----------
which may be modified by Landlord from time to time upon reasonable written
notice from Landlord to Tenant; provided that the same or any such modifications
thereto are reasonable and do not discriminate against any tenant of the
Building.

     (l)  Monitor issuance of keys.  Unless specifically provided otherwise in
the Lease, all keys and/or Building security card devices for access to the
Premises and Building are provided at Tenant's cost after Tenant receives its
initial allotment of two (2) keys and/or Building security card devices per
1,000 square feet of useable square feet in the Premises.  Any re-keying of the
Premises and/or Building due to lost or missing keys shall be at Tenant's cost.
No additional locks shall be placed upon any doors without the written consent
of Landlord.  Additional keys and/or Building security card devices shall be
furnished at Tenant's cost.  Upon termination of this Lease, all keys and
Building security card devices shall be surrendered to Landlord.

     (m)  Install Tenant's communications equipment and cabling in accordance
with Landlord's Building Rules and Regulations.

     (n)  Remove, upon Landlord's request, all cabling provided in Tenant's
Premises, at Tenant's sole cost, upon Lease termination.

     (o)  Not place any other equipment of any kind or nature whatsoever which
will or may necessitate any changes, replacements or additions to or require the
use of the water system, plumbing system, heating system, air conditioning
system or the electrical system of the Premises or Building without the prior
written consent of Landlord, which consent shall not be unreasonably withheld,
unreasonably conditioned or unreasonably delayed, unless Tenant agrees, after
Landlord gives thirty (30) days' prior written notice to Tenant of the actual
cost of such changes, replacements or additions or the actual usage costs of
such systems, to reimburse Landlord for any such actual costs.

          All heating, ventilation and air conditioning (HVAC) equipment
installed in the Premises for Tenant's specific requirements, separate or in
addition to the Building HVAC system, shall be maintained at Tenant's sole cost
and expense.  Any maintenance contractor hired by Tenant to maintain or repair
Tenant's separate HVAC equipment must have Landlord's written approval in
advance of any work, which approval shall not be unreasonably withheld,
unreasonably conditioned or unreasonably delayed.

     (p)  Comply with the Americans Disabilities Act with respect to Tenant's
use and occupancy of the Premises.

________________________________________________________________________________

                       10.     ASSIGNMENT AND SUBLETTING
________________________________________________________________________________

     (a)  Except as specifically provided otherwise in this Section 10, Tenant
shall not, either voluntarily or by operation of law, assign, hypothecate or
transfer this Lease, or sublet the Premises or any part thereof, without the
prior written consent of Landlord in each instance, which consent shall not be
unreasonably withheld, unreasonably conditioned, or unreasonably delayed.

                                      21
<PAGE>

     (b)  In the event Tenant desires to assign, hypothecate or otherwise
transfer this Lease or sublet the Premises, then at least fifteen (15) days
prior to the date when Tenant desires the assignment or sublease to be effective
(the "Assignment Date"), Tenant shall give Landlord a written notice (the
"Assignment Notice"), which shall set forth the name, address and business of
the proposed assignee or sublessee, information (including references)
concerning the character, ownership, and financial condition of the proposed
assignee or sublessee, the Assignment Date, any ownership or commercial
relationship between Tenant and the proposed assignee or sublessee, and the
consideration and all other material terms and conditions of the proposed
assignment or sublease, all in such detail as Landlord shall reasonably require.
Within five (5) business days after Landlord's receipt of Tenant's Assignment
Notice, Landlord shall notify Tenant of whether or not Landlord consents to the
proposed transfer (but Landlord shall not be required to actually execute
transfer documents within such five day period) or if Landlord needs additional
detail.  If Landlord requests additional detail, the Assignment Notice shall not
be deemed to have been received until Landlord receives such additional detail
and Landlord may withhold consent to any assignment or sublease until such
information is provided to it.  Without limiting Landlord's right to withhold
consent to a proposed sublease for other reasons, Landlord shall have the right
to withhold consent to a proposed sublease which is a "Qualifying Transfer" as
defined in subsection 10(f) below if, in Landlord's reasonable judgment, the
proposed sublease is on terms and conditions which are below the then current
fair market terms and conditions for comparable space in a comparable building.

     (c)  The subletting of substantially all of the Premises for all or any
part of the remaining Term of this Lease shall be deemed an assignment rather
than a sublease for purposes of this clause. Notwithstanding the foregoing,
Landlord shall consent to the assignment or transfer, if the Assignment Notice
states that Tenant desires to assign the Lease to any entity into which Tenant
is merged, with which Tenant is consolidated, with which Tenant completes a
share exchange, or which acquires all or substantially all of the assets of
Tenant or all or substantially all of the outstanding shares of capital stock of
Tenant (a "Permitted Assignee"), provided that the assignee first executes,
acknowledges and delivers to Landlord an agreement whereby the assignee agrees
to be bound by all of the covenants and agreements in this Lease which Tenant
has agreed to keep, observe or perform, that the assignee agrees that the
provisions of this Section 10 shall be binding upon it as if it were the
original Tenant hereunder and that the assignee shall have a net worth
(determined in accordance with generally accepted accounting principles
consistently applied) immediately after such assignment which is at least equal
to the net worth (as so determined) of Tenant at the time this Lease was entered
into.

     (d)  If Tenant shall sublet all or any portion of the Premises, then one-
half (1/2) of any consideration paid by the sublessee for the portion of the
Premises being sublet that exceeds the Basic Rent and rental adjustments
provided by this Lease for such portion of the Premises being sublet shall be
due, owing and payable from Tenant to Landlord when paid or owing by the
sublessee under the sublease without any deduction or adjustment whatsoever for
costs incurred by Tenant in connection with the sublease. All costs incurred in
connection with any sublease including, without limitation, brokers fees and
tenant improvement costs, shall be paid by Tenant.

     (e)  Any sale, assignment, hypothecation or transfer of this Lease or
subletting of the Premises that is not in compliance with the provisions of this
Section 10 shall be void and shall, at the option of Landlord, terminate this
Lease.  The consent by Landlord to any assignment or subletting shall not be
construed as relieving Tenant or any assignee of this Lease or sublessee of the
Premises from obtaining the express written consent of Landlord to any further
assignment or subletting, or as releasing Tenant or any assignee or sublessee of
Tenant from any liability or obligation hereunder whether or not then accrued.
Tenant shall pay Landlord as Additional Rent a reasonable fee for costs incurred
in connection herewith, including but not limited to costs for attorneys,
accountants, architects, Tenant Improvement oversight and administration at the
time Tenant requests in writing that Landlord consent to any assignment or
subletting of the Lease.  At a minimum, Landlord shall charge a fee of Five
Hundred and No/100 Dollars ($500.00) for all assignments and subleases which
require or do not require Landlord's consent, whether or not an assignment or
sublease is executed.  This Section 10 shall be fully applicable to all further
sales, hypothecations, transfers, assignments and subleases of any portion of
the Premises by any successors or assignee of Tenant, or any sublessee of the
Premises.

     (f)  For the purposes of this Section 10, a "Qualifying Transfer" shall
mean (i) any proposed assignment of this Lease, (ii) any proposed sublease of
any portion of the Premises with a term expiring within one year of the
expiration date of the Lease Term, (iii) any proposed sublease of any portion of
the Premises with a term of more than

                                      22
<PAGE>

two (2) years, (iv) if Tenant leases two or more floors in the Building, any
proposed sublease of a portion of the Premises which exceeds one full floor, or
(v) if Tenant leases less than two floors in the Building, any proposed sublease
of any portion of the Premises. Notwithstanding any provisions of this Section
10 to the contrary, after the Landlord receives a request from Tenant to consent
to any Qualifying Transfer, Landlord shall have the option, to be exercised by
written notice within thirty (30) days after the receipt of such request, to
terminate this Lease and the Term hereof with respect to the portion of the
Premises covered by the proposed assignment or sublease on not less than thirty
(30) days and not more than ninety (90) days notice to the Tenant. If the
Landlord elects to terminate this Lease as aforesaid, the Tenant shall have the
right, to be exercised by written notice to the Landlord within ten (10) days
after receipt of such notice of termination, to withdraw the request for consent
to the proposed assignment or sublease, in which case the Tenant shall not
proceed with such assignment or sublease, the notice of termination shall be
null and void and this Lease shall continue in full force and effect in
accordance with its terms. In the event Landlord elects to terminate this Lease
as provided herein, then Landlord shall have the additional right to negotiate
directly with Tenant's proposed assignee or subtenant and to enter into a direct
lease with such party on such terms as shall be acceptable to Landlord in its
sole and absolute discretion, and Tenant hereby waives any claims against
Landlord related thereto, including, without limitation, any claims for any
compensation or profit related to such lease. In addition, in the event Landlord
elects to terminate this Lease as provided herein, then upon the applicable
termination date Tenant shall pay to Landlord, as Additional Rent, a termination
fee equal to Landlord's unamortized costs incurred in connection with this Lease
including, without limitation, brokerage fees, tenant improvement allowances,
free rent, and any other concessions granted by Landlord in connection with this
Lease.

     The term "assign," as used herein, shall include an assignment of a part of
interest in this Lease, as well as any assignment from one co-tenant to another;
and an assignment to any prior owner of the Tenant's interest herein or part
thereof.

________________________________________________________________________________

                         11. DAMAGE OR DESTRUCTION
________________________________________________________________________________

     (a)  In the event the Building and/or the Premises is damaged by fire or
other perils covered by Landlord's insurance, Landlord shall:

          i)        In the event of a partial destruction of the Building and/or
the Premises, to an extent not exceeding twenty-five percent (25%) of the full
insurable value thereof, and if the damage thereto is such that the Building
and/or the Premises may be repaired, reconstructed or restored within a period
of one hundred twenty (120) days from the date of the happening of such casualty
and if Landlord will receive insurance proceeds sufficient to cover the cost of
such repairs, then Landlord shall commence and proceed diligently with the work
of repair, reconstruction or restoration and this Lease shall continue in full
force and effect;

          ii)       If such repair, reconstruction, or restoration shall require
a period longer than one hundred twenty (120) days or exceeds twenty-five
percent (25%) of the full insurable value thereof, or if said insurance proceeds
will not be sufficient to cover the cost of such repairs, then Landlord either
may elect to so repair, reconstruct or restore and the Lease shall continue in
full force and effect or Landlord may elect not to repair, reconstruct, or
restore and the Lease shall then terminate; and

          iii)      Under any of the conditions of this subsection 11(a) or
subsection 11(e), Landlord shall give written notice to Tenant of its intention
within ninety (90) days after the occurrence of such damage or destruction.  If
Landlord fails to provide such written notice within such ninety (90) day
period, then Landlord shall be deemed to have elected not to restore the
Building and/or Premises.  In the event Landlord elects not to restore the
Building and/or the Premises, this Lease shall be deemed to have terminated as
of the date of such partial destruction.  In the event Landlord elects to
restore the Building and/or the Premises, but it is reasonably estimated that
such restoration will take longer than ten (10) months from the date of the
casualty, then Tenant may terminate this Lease on written notice to Landlord.

     Notwithstanding anything contained in this Section 11(a) to the contrary,
provided that Tenant leases at least fifty percent (50%) of the Building, if any
casualty does not render the Premises untenantable, regardless of the amount

                                      23
<PAGE>

of damage or destruction to the remainder of the Building, then Landlord shall
not have the right to terminate this Lease under this Section 11(a).

     (b)  Upon any termination of this Lease under any of the provisions of this
Section 11, the parties shall be released without further obligation to the
other from the date possession of the Premises is surrendered to Landlord except
for items which have theretofore accrued and are then unpaid; provided that
Landlord shall, upon such termination, return to Tenant any unearned Rent or
other unearned sums paid to Landlord.

     (c)  In the event of repair, reconstruction, or restoration by Landlord as
herein provided, the Rental payable under this Lease shall be abated
proportionately with the degree to which Tenant's use of the Premises is
impaired during the period of such repair, reconstruction or restoration.
Tenant's recovery for damages, if any, is limited to Rental abatement.  Tenant
shall not be entitled to any compensation or damages for loss in the use of the
whole or any part of the Premises and/or any inconvenience or annoyance
occasioned by any damage, repair, reconstruction or restoration.

     (d)  Tenant shall not be released from any of its obligations under this
Lease except to the extent and upon the conditions expressly stated in this
Section 11 or as otherwise provided in this Lease.  Notwithstanding anything to
the contrary contained in this Section 11, if Landlord is delayed or prevented
from repairing or restoring the damaged Premises within one year after the
occurrence of such damage or destruction by reason of acts of God, war,
governmental restrictions, inability to procure the necessary labor or materials
after diligent efforts to obtain such labor or materials, or other cause beyond
the reasonable control of Landlord, Landlord shall be relieved of its obligation
to make such repair or restoration and Tenant shall be released from its
obligations under this Lease as of the end of said one year period and this
Lease shall be deemed terminated.

     (e)  If damage is due to any cause other than fire or other peril covered
by extended coverage insurance, Landlord may elect to terminate this Lease.

     (f)  If Landlord is obligated to or elects to repair or restore as herein
provided, Landlord shall be obligated to make repair or restoration only of
those portions of the Building and/or the Premises which were originally
provided at Landlord's expense, and the repair and restoration of items not
provided at Landlord's expense shall be the obligation of Tenant.

     (g)  Notwithstanding anything to the contrary contained in this Section 11,
Landlord shall not have any obligation whatsoever to repair, reconstruct or
restore the Premises when the damage resulting from any casualty covered under
this Section 11 occurs during the last twelve (12) months of the then current
Term of this Lease.  However, if Landlord chooses not to restore, Tenant may
elect to terminate this Lease.

________________________________________________________________________________

                            12. INDEMNIFICATION
________________________________________________________________________________

     (a)  Tenant shall indemnify, defend and hold Landlord harmless from all
claims arising from Tenant's use of the Premises or the conduct of its business
or from any activity, work, or thing done, permitted or suffered by Tenant in or
about the Premises.  Tenant shall further indemnify, defend and hold Landlord
harmless from all claims arising from any breach or default in the performance
of any obligation to be performed by Tenant under the terms of this Lease, or
arising from any act, neglect, fault or omission of Tenant or of its agents or
employees, and from and against all costs, reasonable attorneys' fees, expenses,
and liabilities incurred in or about such claim or any action or proceeding
brought thereon.  In case any action or proceeding shall be brought against
Landlord by reason of any such claim, Tenant upon notice from Landlord shall
defend the same at Tenant's expense by counsel approved in writing by Landlord;
provided that the foregoing provision shall not be construed to make Tenant
responsible for loss, damage, liability or expense resulting from injuries to
third parties caused by the negligence of Landlord, or its officers,
contractors, agents or employees.

     (b)  Landlord shall indemnify, defend and hold Tenant harmless from all
claims arising from any activity, work or thing done or permitted by Landlord in
or about the Building, Land or Common Area.  Landlord shall further indemnify,
defend and hold Tenant harmless from all claims arising from any breach or
default in the performance of

                                      24
<PAGE>

any obligation to be performed by Landlord under the terms of this Lease, or
arising from any act, neglect, fault or omission of Landlord or of its agents or
employees, and from and against all costs, reasonable attorneys' fees, expenses,
and liabilities incurred in or about such claim or any action or proceeding
brought thereon. In case any action or proceeding shall be brought against
Tenant by reason of any such claim, Landlord, upon notice from Tenant, shall
defend the same at Landlord's expense by counsel approved in writing by Tenant;
provided that the foregoing provision shall not be construed to make Landlord
responsible for loss, damage, liability or expense resulting from injuries to
third parties caused by the negligence of Tenant, or its officers, contractors,
agents or employees.

     (c)  Notwithstanding anything contained above in this Section, in the event
of concurrent negligence of Tenant, its agents, employees or contractors, on the
one hand, and that of Landlord, its agents, employees or contractors on the
other hand, which concurrent negligence results in injury or damage to persons
or property, either party's obligation to indemnify the other as set forth in
this Section shall be limited to the extent of the negligence of the
indemnifying party and that of its agents, employees or contractors, including
the indemnifying party's proportional share of costs, attorneys' fees and
expenses incurred in connection with any claim, action or proceeding brought
with respect to such injury or damage.

________________________________________________________________________________

                      13. DAMAGE TO TENANT'S PROPERTY
________________________________________________________________________________

     Notwithstanding anything in this Lease to the contrary, Landlord or its
agents shall not be liable for any damage to Tenant's property which is caused
by the following:

     (a)  Any damage to any property entrusted to employees of the Landlord;

     (b)  Loss or damage to any property by theft or otherwise unless caused by
Landlord's or Landlord's employees' negligence or willful misconduct and not
covered by Tenant's insurance;

     (c)  Any injury or damage to property resulting from fire, explosion,
falling plaster, steam, gas, electricity, water or rain which may leak from any
part of the Building or the pipes, appliances or plumbing work therein or from
the roof, street or sub-surface or from any other place or resulting from
dampness unless caused by Landlord's or Landlord's employees' negligence or
willful misconduct and not covered by Tenant's insurance; and

     (d)  Landlord or its agents shall not be liable for interference with light
or other incorporeal hereditaments, nor shall Landlord be liable for any latent
defect in the Premises or in the Building; provided that nothing in this Section
13(d) shall release Landlord from its duties under this Lease to repair any
latent defects in the Premises or Building within a reasonable time after
receiving notice of such defects.

     Tenant shall give prompt notice to Landlord in case of fire or accidents in
the Premises or in the Building or of defects therein or in the fixtures or
equipment.

________________________________________________________________________________

                               14. INSURANCE
________________________________________________________________________________

    (a)   Tenant shall, during the term hereof and any other period of
occupancy, at its sole cost and expense, keep in full force and effect
Commercial General Liability Insurance insuring Tenant against any liability
arising out of lease, use, occupancy or maintenance of the Premises and all
areas appurtenant thereto. Such insurance shall be in the amount of not less
than Three Million and No/100 Dollars ($3,000,000.00) Combined Single Limit for
injury to, or death of one or more persons in an occurrence, and for damage to
tangible property (including loss of use) in an occurrence. The policy shall
insure the hazards of Premises and operations, independent contractors,
contractual liability (covering the indemnity contained in Section 12 hereof)
and shall (1) name Landlord as an additional insured, and (2) contain a
provision that "the insurance provided Landlord hereunder shall be primary and
non-contributing with any other insurance available to Landlord."

     (b)  Landlord shall, during the term hereof any other period of occupancy
by Tenant, keep in full force and effect the following insurance:

                                      25
<PAGE>

          i)        Commercial General Liability Insurance insuring Landlord
against any liability arising out of Landlord's use, occupancy or maintenance of
the Building and Land and all areas appurtenant thereto. Such insurance shall be
in the amount of not less than Three Million and No/100 Dollars ($3,000,000.00)
Combined Single Limit for injury to, or death of one or more persons in an
occurrence, and for damage to tangible property (including loss of use) in an
occurrence. The policy shall insure the operations of the Building and Land and
of independent contractors, and include contractual liability (covering the
indemnity contained in Section 12 hereof) and shall contain a provision that
"the insurance provided Tenant hereunder shall be primary and non-contributing
with any other insurance available to Tenant."

          ii)       Property insurance together with coverage for earthquake
(excluding any property which Tenant is obligated to insure), for the full
replacement value of the Building, and all improvements and betterments to the
Building, with a deductible not to exceed twenty thousand dollars ($20,000.00).


     (b)  All policies shall be written in a form satisfactory to Landlord and
shall be taken out with insurance companies holding a General Policyholders
Rating of "A" and a Financial Rating of "A5" or better, as set forth in the most
current issue of Bests Insurance Guide.  Within five (5) days after occupancy of
the Premises, Tenant shall deliver to Landlord certificates evidencing the
existence of the amounts and forms of coverage required above.  No such policy
shall be cancelable or reducible in coverage except after thirty (30) days prior
written notice to Landlord.  Tenant shall within ten (10) days prior to the
expiration of such policies, furnish Landlord with renewals or "binders"
thereof, or Landlord may order such insurance and charge the cost thereof to
Tenant as Additional Rent.  If Landlord obtains any insurance that is the
responsibility of Tenant under this Section 14, Landlord shall deliver to Tenant
a written statement setting forth the cost of any such insurance and showing in
reasonable detail the manner in which it has been computed.

________________________________________________________________________________

                   15. WAIVER OF SUBROGATION AND RELEASE
________________________________________________________________________________

     Notwithstanding anything to the contrary contained in this Lease, Landlord
and Tenant, for themselves and their respective insurers, each release the other
from liability and waive any and all rights to recover against the other for any
loss or damage to the property of such waiving party, both real and personal and
including without limitation earnings derived from such property,
notwithstanding that any such loss or damage may be due to or result from the
negligence of either of the parties hereto or their respective employees or
agents; provided, that this waiver shall not affect or relieve Tenant of its
obligation to maintain the Premises, or the right of Landlord to recover against
Tenant the amount of any deductible under Landlord's insurance where Tenant
causes the damage covered by Landlord's insurance.  Each party shall  make
reasonable attempts to obtain a written consent to the waiver of subrogation
contained in this Section from its insurer.

________________________________________________________________________________

                             16. EMINENT DOMAIN
________________________________________________________________________________

     If more than twenty-five percent (25%) of the Building shall be taken or
condemned for public or quasi-public use, under any statute or by right of
eminent domain, or private purchase in lieu thereof, by any competent authority,
Tenant shall have no claim against Landlord and shall not have any claim or
right to any portion of the amount that may be awarded as damages or paid as a
result of any such condemnation.  All rights of the Tenant to damages therefore
are hereby assigned by the Tenant to Landlord; provided, nothing contained in
this Section 16 shall be deemed to give Landlord any interest in any award made
to Tenant for the taking of personal property and fixtures belonging to Tenant
or for any relocation costs provided to Tenant, and Tenant shall have the right
to claim the same from such condemning authority.  Upon such condemnation or
taking, at the option of either Landlord or Tenant, the term of this Lease shall
cease and terminate from the date such governmental agency takes possession, and
the Tenant shall have no claim against Landlord for the value of any unexpired
term of the Lease.  If less than twenty-five percent (25%) of the Building shall
be so taken, but if such taking shall substantially affect the Premises or the
means of access thereto, or if such taking shall be of a material part of the
Premises, Landlord or Tenant shall have the right, by delivery of notice in
writing to the other party, to terminate this Lease as of the date when
possession shall be so taken.  If neither party shall so elect, this Lease shall
be and remain unaffected by such taking except that, effective as of the date

                                      26
<PAGE>

when possession shall be so taken, the Rent payable hereunder shall be
diminished by an amount which shall bear the same ratio to the rent as the area
of the part of the Premises taken bears to the area of the Premises before such
taking.

________________________________________________________________________________

                               17. BANKRUPTCY
________________________________________________________________________________

     If Tenant shall file a petition in bankruptcy under any provision of the
Bankruptcy Code as then in effect, or if Tenant shall be adjudicated bankrupt in
involuntary bankruptcy proceedings and such adjudication shall not have been
vacated within thirty (30) days from the date thereof, or if a receiver or
trustee shall be appointed of Tenant's property and the order appointing such
receiver or trustee shall not be set aside or vacated within sixty (60) days
after the entry thereof, or if Tenant shall assign Tenant's estate or effects
for the benefit of creditors, or if this Lease shall, by operation of law or
otherwise, pass to any person or persons other than Tenant, then in any such
event Landlord may terminate this Lease, if Landlord so elects, with or without
notice of such election and with or without entry or action by Landlord.  In
such case, notwithstanding any other provisions of this Lease, Landlord, in
addition to any and all rights and remedies allowed by law or equity, shall,
upon such termination, be entitled to recover damages in the amount provided for
by Section 18 of this Lease.  Neither Tenant nor any person claiming through or
under Tenant or by virtue of any statute or order of any court shall be entitled
to possession of the Premises but shall surrender the Premises to Landlord.
Nothing contained herein shall limit or prejudice the right of Landlord to
recover damages by reason of any such termination equal to the maximum allowed
by any statute or rule of law in effect at the time when, and governing the
proceedings in which, such damages are to be proved; whether or not such amount
is greater, equal to, or less than the amount of damages recoverable under the
provisions of this Section 17.

________________________________________________________________________________

                          18. DEFAULT AND REMEDIES
________________________________________________________________________________

     (a)  The occurrence of any one or more of the following events shall
constitute a default hereunder by Tenant:

          i)        The abandonment of the Premises by Tenant. Abandonment is
herein defined to include, but is not limited to, any absence by Tenant from the
Premises for ten (10) business days or longer while Tenant is in default of any
provisions or term of this Lease.

          ii)       The failure by Tenant to make any payment of Rent or any
other payment required to be made by Tenant hereunder within ten (10) days after
written notice from Landlord that such payment is overdue.

          iii)      The failure by Tenant to observe or perform any of the
express or implied covenants or provisions of this Lease to be observed or
performed by Tenant, other than as specified in (i) or (ii) above, where such
failure shall continue for a period of ten (10) days after written notice
thereof from Landlord to Tenant. If the nature of Tenant's default is such that
more than ten (10) days are reasonably required for its cure, then Tenant shall
not be deemed to be in default if Tenant shall commence such cure within said
ten (10) day period and thereafter diligently prosecute such cure to completion,
which completion shall occur not later than sixty (60) days from the date of
such notice from Landlord.

          iv)

                    a)  The making by Tenant of any general assignment for the
benefit of creditors;

                    b)  The filing by or against Tenant of a petition to have
Tenant adjudged a bankrupt or a petition for reorganization or arrangement under
any law relating to bankruptcy (unless, in the case of a petition filed against
Tenant, the same is dismissed within sixty (60) days);

                    c)  The appointment of a trustee or receiver to take
possession of substantially all of Tenant's assets located at the Premises or of
Tenant's interest in this Lease, where possession is not restored to Tenant
within sixty (60) days; or

                                      27
<PAGE>

                    d)  The attachment, execution or other judicial seizure of
substantially all of Tenant's assets located at the Premises or of Tenant's
interest in this Lease where such seizure is not discharged within sixty (60)
days.

     (b)  In the event of any such default by Tenant, in addition to any other
remedies available to Landlord at law or in equity, Landlord shall have the
immediate option to terminate this Lease and all rights of Tenant hereunder. In
the event that Landlord shall elect to so terminate this Lease then Landlord may
recover from Tenant:

          i)        The amount of any unpaid Rent which had been earned at the
time of such termination; plus

          ii)       The amount by which the unpaid Rent which would have been
earned after termination and for the present value at the time of the award of
the amount by which the unpaid Rent for the balance of the Lease Term exceeds
the amount of such Rental loss that Tenant proves could have been reasonably
avoided; plus

          iii)      Any interest charged on delinquent Rent; plus

          iv)       The reasonable costs incurred by Landlord in reletting the
Premises which costs shall include, but not be limited to, real estate broker's
fees incurred by Landlord, the reasonable costs of repairing the Premises and
putting the same into a tenantable condition, and an amount equal to the
difference between the Basic Rent as specified in this Lease and the basic rent
payable by the replacement tenant(s) (provided such basic rent is substantially
similar to fair market rent for such space),, but shall exclude the cost of
tenant improvements, alterations, renovations and decorating the Premises for
the new tenant(s), any allowances or credits which Landlord grants such new
tenant(s), any expenses or costs related to any assumption by Landlord of the
lease of such replacement tenant(s);, and the attorneys' fees and costs incurred
by Landlord; plus

          v)        Any other amount necessary to compensate Landlord for all
the actual damages proximately caused by Tenant's failure to perform Tenant's
obligation under this Lease.

     (c)  In the event of any such default by Tenant, and in addition to all
other remedies, Landlord shall also have the right, with or without terminating
this Lease, to re-enter the Premises and remove all persons and property from
the Premises; such property may be removed and stored in a public warehouse or
elsewhere at the cost of and for the account of Tenant. Landlord shall be
entitled to hold and sell Tenant's property in a commercially reasonable manner
as specified in the Uniform Commercial Code as enacted in the State of
Washington. No re-entry or taking possession of the Premises by Landlord
pursuant to this Section 18 shall be construed as an election to terminate this
Lease unless a written notice of such intention is given to Tenant or unless the
termination thereof is decreed by a court of competent jurisdiction.

     (d)

          i)        In the event of any such default by Tenant and in the event
that Landlord shall elect to re-enter as provided above or shall take possession
of the Premises pursuant to legal proceeding or pursuant to any notice provided
by law, Landlord may from time to time, without terminating this Lease, and
without waiving its right to recover all Rent as it becomes due, relet the
Premises or any part thereof for the Term of this Lease on terms and conditions
as Landlord in its sole discretion may deem advisable with the right to make
alterations and repairs to the Premises.

          ii)       In the event that Landlord shall elect to so relet, then
Rentals received by Landlord from such reletting shall be applied; first, to the
payment of any cost of such reletting (including the costs described in
subsection 18(b)(iv) above); second, to the payment of the cost of any
alterations and repairs to the Premises; third, to the payment of an
indebtedness other than Rent due hereunder from Tenant to Landlord; and fourth,
to the payment of Rent due and unpaid hereunder, and the residue, if any, shall
be held by Landlord and applied to payment of future Rent as the same may become
due and payable hereunder. Should the portion of such Rentals received from such
reletting during any month, which is applied to the payment of Rent hereunder,
be less than the Rent payable during

                                      28
<PAGE>

that month by Tenant hereunder, then Tenant shall pay such deficiency to
Landlord immediately upon demand therefor by Landlord.

     (e)  Tenant acknowledges that certain benefits or concessions provided by
Landlord are conditioned upon Tenant's timely, full and faithful performance of
each and every obligation, covenant, representation and warranty of this Lease
throughout the entire Term, even though such benefits or concessions may be
realized by Tenant over less than the entire Term.  Accordingly, notwithstanding
anything to the contrary contained herein, in the event Landlord brings an
action against Tenant for default under this Lease, Landlord shall become
immediately entitled to receive from Tenant as Additional Rent the amount of all
such benefits and concessions allocable to the balance of the Lease term on a
pro rata basis, including, without limitation,

          i)        any amounts theretofore paid by Landlord to Tenant or to any
third party or any amounts credited to Tenant or to any third party, for or on
account of

                    a)  any moving, tenant improvement, decorating or other
allowance or credit granted to Tenant,

                    b)  any real estate commission paid on account of this
Lease,

                    c)  any expenses or costs related to assumption by Landlord
of any other lease, plus

          ii)       Rent for any period for which this Lease provides any zero
or nominal Rent, including any period of early occupancy of the Premises prior
to the commencement of the Term of this Lease, plus

          iii)      The amount spent by Landlord for any tenant improvements to
the Premises.

     (f)  All rights, options and remedies of either party contained in this
Lease shall be construed and held to be cumulative, and no one of them shall be
exclusive of the other, and the parties shall have the right to pursue any one
or all of such remedies or any other remedy or relief which may be provided by
law, whether or not stated in this Lease.  No waiver of any default of either
party hereunder shall be implied from any acceptance by the non-defaulting party
of any Rent or other payments due hereunder or any omission by the non-
defaulting party to take any action on account of such default if such default
persists or is repeated, and no express waiver shall affect defaults other than
as specified in said waiver.  The consent or approval of Landlord to or of any
act by Tenant requiring Landlord's consent or approval shall not be deemed to
waive or render unnecessary Landlord's consent or approval to or of any
subsequent similar acts by Tenant.

     (g)  Landlord shall be in default under this Lease if  Landlord fails to
make any payment required to be made by Landlord hereunder within ten (10) days
after written notice from Tenant that such payment is overdue. Landlord shall
also be in default in the performance of any non-monetary obligation required to
be performed by Landlord under the Lease if Landlord has failed to perform such
obligation within thirty (30) days after the receipt of notice from Tenant
specifying in detail Landlord's failure to perform; provided, however, that if
the nature of Landlord's obligation is such that more than thirty (30) calendar
days are required for its performance, then Landlord shall not be deemed in
default if it shall commence such performance within thirty (30) days and
thereafter diligently pursues the same to completion.

     (h)  Notwithstanding anything herein to the contrary, both Landlord and
Tenant shall have the obligation to take reasonable steps to mitigate their
damages caused by any default under this Lease.

     (i)  Except with respect to actions by Landlord to recover possession of
the Premises through an unlawful detainer or similar procedure, and except with
respect to emergency matters for which a restraining order or other similar
equitable relief is necessary, the parties agree to attempt to resolve any
disputes under this Lease as follows: both parties covenant to provide a person
authorized and empowered to resolve any dispute that may arise to meet face to
face with the person from the other party upon ten (10) days prior notice at a
mutually convenient place. Such persons shall negotiate in good faith to attempt
to resolve the dispute for as long as either party so desires and in

                                      29
<PAGE>

good faith believes progress can be made, but no party shall be obligated to
continue negotiations for longer than ten (10) days. Failing a resolution of the
dispute by this method, the parties shall submit to non-binding mediation of the
dispute with a mediator of their choice with experience in mediating commercial
disputes. Both parties shall pay an equal share of the fees of the mediator
prior to the commencement of the mediation. Otherwise the parties shall each pay
their own costs and expenses of such mediation. Failing resolution of the
dispute by this method, the parties shall resort to any other remedies provided
at law.

________________________________________________________________________________

                     19. SUBORDINATION, QUIET ENJOYMENT
________________________________________________________________________________

     (a)  Without the necessity of any additional document being executed by
Tenant for the purpose of effective subordination, and at the election of
Landlord or any mortgagee or beneficiary of a deed of trust with a lien on the
Building, Common Areas, or Land or any ground lessor (collectively referred to
in this Lease as "Mortgagee"), this Lease shall be subject and subordinate at
all times to:

          i)        All ground leases or underlying leases which may now exist
or hereafter be executed affecting the Building, Common Areas or the Land or
both; and

          ii)       The lien of any mortgage or deed of trust which may now
exist or hereafter be executed in any amount for which the Building, Common
Areas, Land, ground leases or underlying leases, or Landlord's interest or
estate in any of said items is specified as security (collectively referred to
as "Mortgages").

     (b)  Notwithstanding the foregoing, Landlord shall have the right to
subordinate or cause to be subordinated any such ground leases or underlying
leases or Mortgages to this Lease.

     (c)  In the event that any ground lease or underlying lease terminates for
any reason or any Mortgage is foreclosed or a conveyance in lieu of foreclosure
is made for any reason, Tenant shall, notwithstanding any subordination, attorn
to and become the Tenant of the successor-in-interest to Landlord, at the option
of such successor-in-interest. Tenant covenants and agrees to execute and
deliver, upon demand by Landlord and in the form reasonably requested by
Landlord, any reasonable additional documents evidencing the priority of
subordination of this Lease with respect to any such ground leases or underlying
leases or the lien of any such Mortgage. Should Tenant fail to sign and return
any such documents within twenty (20) business days of such request, Tenant
shall, at Landlord's election, be in default under this Lease.

     (d)  The provisions of subsections (a) and (c) of this Section are
conditioned upon Landlord obtaining and delivering to Tenant a nondisturbance
agreement in which any Mortgagee currently or hereafter holding a Mortgage to
which this Lease is to be subordinate agrees to recognize this Lease upon
foreclosure, trustee's sale or deed in lieu thereof so long as Tenant is not in
default under this Lease; provided that, even if Landlord has not obtained such
a nondisturbance agreement, in the event of any such subordination of this Lease
by operation of law or otherwise, Tenant's possession of the Premises shall
remain undisturbed and Tenant's rights under this Lease shall be recognized and
shall not be adversely affected so long as Tenant is not in default under this
Lease, including upon any foreclosure, trustee's sale or deed in lieu thereof.

________________________________________________________________________________

                         20. ESTOPPEL CERTIFICATES
________________________________________________________________________________

     Tenant shall, from time to time, upon written request of Landlord, execute,
acknowledge and deliver to Landlord or its designee a written statement stating:
the date this Lease was executed; the Term Commencement Date, as well as the
date of Term expiration; the date Tenant entered into occupancy of the Premises;
the amount of minimum monthly Rental and the date through which such Rental has
been paid; and certifying to the extent true:  that this Lease is in full force
and effect and has not been assigned, modified, supplemented or amended in any
way (or specifying the date of the agreement so affecting this Lease); that this
Lease represents the entire agreement between the parties as to this leasing;
that all conditions under this Lease to be performed by Landlord have been
satisfied; that all required contributions by Landlord to Tenant on account of
Tenant's improvements have been received; that on this date there are no
existing defenses or offsets which the Tenant has against the enforcement of
this Lease by Landlord, and that not more than one month's Rental has been paid
in advance; and such other matters as Landlord may reasonably request.  It

                                      30
<PAGE>

is intended that any such statement delivered pursuant to this paragraph may be
relied upon by a prospective purchaser of Landlord's interest or a mortgagee of
Landlord's interest or assignee of any mortgage upon Landlord's interest in the
Building. If Tenant shall fail to respond within ten (10) business days of
receipt by Tenant of a written request by Landlord as herein provided, Tenant
shall be deemed to have given such certificate as above provided without
modification and shall be deemed to have admitted the accuracy of any
information supplied by Landlord to a prospective purchaser or mortgagee, that
this Lease is in full force and effect, that there are no uncured defaults in
Landlord's performance, that the Security Deposit is as stated in this Lease,
and that not more than one month's Rental has been paid in advance.

________________________________________________________________________________

                            21. ATTORNEYS' FEES
________________________________________________________________________________

     (a)  Payment to Prevailing Party.  If either party shall bring an action or
          ---------------------------
proceeding (including, without limitation, any cross-complaint, counterclaim or
third party claim) against any other party by reason of the breach or alleged
violation of any covenant, term or obligation hereof, or for the enforcement of
any provision hereof, or to interpret the Lease, or for any other claim
otherwise arising out of this Lease, the Prevailing Party (as defined below) in
such action or proceeding shall be entitled to its costs and expenses of suit,
including but not limited to reasonable attorneys' fees, which shall be payable
whether or not such action is prosecuted to judgment.  "Prevailing Party" within
the meaning of this Section 21 shall include, without limitation, a party who
dismisses an action for recovery hereunder in exchange for payment of the sums
allegedly due, performance of covenants allegedly breached or consideration
substantially equal to the relief sought in the action.

     (b)  Attorneys' Fees in Third Party Litigation.   If either party is
          -----------------------------------------
required to initiate or defend any action or proceeding with a third party
(including, without limitation, any cross-complaint, counterclaim or third party
claim) because of the other party's breach of this Lease, or otherwise arising
out of this Lease, and such party is the Prevailing Party in such action or
proceeding, then the party so initiating or defending shall be entitled to
reasonable attorneys' fees from the other party.

     (c)  Scope of Fees.  Attorneys' fees under this Section 21 shall include
          -------------
attorneys' fees on any appeal, attorney fees on any confirmation of an
arbitration award or in enforcing any judgment on an arbitration award, and, in
addition, a party entitled to attorneys' fees shall be entitled to all other
reasonable costs and expenses occurred in connection with such action.

________________________________________________________________________________

                              22. LATE CHARGES
________________________________________________________________________________

     Tenant acknowledges that a late payment of Rent or other sums due hereunder
will cause Landlord to incur costs not contemplated by this Lease, the exact
amount of which is difficult to ascertain.  Such costs may include, but not be
limited to, processing and accounting charges, and penalties imposed by terms of
any contracts, mortgages or deeds of trust covering the Building.  Therefore, in
the event Tenant should fail to pay any installment of Rent or any sum due
hereunder within five (5) days after written notice from Landlord that such
amount is due, then Tenant shall pay Landlord as Additional Rent, a late charge
equal to five percent (5%) of the amount owing.  Notwithstanding the above,
nothing contained in this Section 22 shall be deemed to preclude Landlord from
exercising any other right or remedy Landlord may have under this Lease in law
or equity, in addition to or in lieu of the above late charges.  Tenant shall
also pay Landlord an "NSF" fee of Fifty and No/100 Dollars ($50.00) for all
checks of Tenant returned for insufficient funds.

________________________________________________________________________________

                                23. NOTICES
________________________________________________________________________________

     Any notice required or permitted to be given hereunder must be in writing
and may be given by personal delivery, overnight air courier or by mail, and if
given by mail shall be mailed by certified mail, return receipt requested,
addressed to Tenant or to Landlord at the addresses designated in subsection
1(h).  Notice shall be deemed sufficiently given

     (a)  When tendered, if written notice is personally delivered; or

                                      31
<PAGE>

     (b)  On the date delivered (or on the date delivery is refused) if sent by
overnight air courier; or

     (c)  If mailed, forty-eight (48) hours after deposit of the above-described
certified mail with the United States Postal Service.  Either party may specify
a different address for notice purposes by written notice to the other.

________________________________________________________________________________

                              24. HOLDING OVER
________________________________________________________________________________

     Should Tenant continue to occupy the Premises after expiration or
termination of the Term or any renewal or renewals thereof with Landlord's
written consent, such tenancy shall be from month-to-month at a monthly Rent
equal to one hundred fifty percent (150%) of the Rent and Additional Rent paid
for the last month of the Term of this Lease and all other charges due hereunder
for each month or any part thereof of any such holdover period.  In the event of
any unauthorized holding over by Tenant, Tenant shall indemnify Landlord against
all claims for damages by any other tenant to whom Landlord may have leased all
or any part of the Premises covered hereby effective upon termination of this
Lease.

________________________________________________________________________________

                              25. ALTERATIONS
________________________________________________________________________________

     (a)  Approval Process.
          ----------------

          i)        Interior Finishes or Structural Work.  Tenant shall not make
                    ------------------------------------
or cause to be made interior finish work (alterations, additions or
improvements) to the Premises or structural interior alterations (structural
interior alterations include but are not limited to alterations involving the
Building electrical, mechanical, plumbing, fire safety, life or other Building
systems), without the prior written approval of Landlord, which approval shall
not be unreasonably withheld, unreasonably conditioned or unreasonably delayed.
All contractors used by Tenant shall be licensed and bonded and approved by
Landlord in writing and in advance of any work.  In addition, Tenant and
Tenant's contractor shall comply with the terms and conditions provided in the
Construction Rules and Regulations attached hereto as  Exhibit "G."  Tenant
                                                       -----------
shall provide Landlord with written notice of its intent to make changes at
least thirty (30) days prior to the start of any proposed work.  Notice shall
include detailed information concerning the following items:

                    (a)  General description of the changes to be made including

     Notwithstanding the above to the contrary, in the event any proposed
alterations are estimated by Landlord to cost in excess of $15,000.00, Landlord
shall have the right, in Landlord's sole discretion, to contract directly with
the approved contractor for the installation of the alterations.  If Landlord
contracts directly with the approved contractor for the installation of the
alterations, (1) Tenant shall reimburse Landlord for the costs of installation,
as Additional Rent, within ten (10) days of Tenant's receipt of an invoice for
such costs and/or, at Landlord's election, Tenant shall deposit with Landlord

require a lien search on the Land at Tenant's cost and expense.  Tenant
covenants and agrees that all work done shall comply with the requirements of
all governmental agencies, offices and boards having jurisdiction over the
Premises.  Further, Tenant shall provide to Landlord, within thirty (30) days of
completion of any work, copies of all as-builts and plans and specifications

such installation, reasonable wear and tear and damage by Landlord, casualty or
condemnation excepted. Notwithstanding the foregoing sentence, Tenant shall be
obligated to remove, at Tenant's cost, all cabling within the Premises, and to
restore the Premises to the condition it was in prior to the installation of
such cabling, reasonable wear and tear excepted. At the expiration or earlier
termination of this Lease, all alterations, additions or improvements made by
Tenant after the Commencement Date shall, at Tenant's option (unless otherwise

caused by fire or other casualty, condemnation or Landlord excepted), or shall
become the property of Landlord, free and clear of liens, claims and
encumbrances, to remain upon and be surrendered with the Premises.
Notwithstanding anything to the contrary herein, all movable partitions,
business and trade fixtures, machinery and equipment, communications equipment
and office equipment affixed to or located within the Premises, which can be
removed without damage to the Building, shall remain the property of Tenant;
provided, Tenant shall promptly repair any damage to the Premises and Building
upon their removal. Furniture, furnishings and other articles of personal
property owned by Tenant and located in the Premises shall be and remain the
property of Tenant and may be removed by Tenant at any time during the Term and
any extensions thereof.

All alterations to the Premises with or without Landlord's written approval
shall be made in accordance with Landlord's Construction Rules and Regulations
attached hereto as Exhibit "G."  Landlord reserves the right to modify such
                   ----------
rules and regulations as Landlord determines in its sole discretion; provided
such modifications are reasonable and do not discriminate against any tenant of
the Building.

actions, Landlord's inability to obtain permits or other governmental approvals,
inability to obtain materials, or damage to work in progress by reason of fire
or other casualty, or other cause beyond the reasonable control of said party

     (a)  Accord and Satisfaction.  No payment by Tenant or receipt by Landlord
          -----------------------
of a lesser amount than any installment or payment of the Rent due shall be
deemed to be other than on account of the amount due, nor shall any endorsement
or statement on any check or any letter accompanying any check or payment as
Rent be deemed an accord and satisfaction.  Landlord's right to recover the

question, of the fee title of the Premises or the lessees under any master
lease, if any.  In the event of any transfer, assignment or other conveyance or

subsequent transfer shall not be deemed a violation on Landlord's part of any of
the terms and conditions of this Lease.

     (h)  Definition of "Tenant".  The word "Tenant", wherever used in this
          ---------------------
Lease, shall be construed to mean tenants in all cases where there is more than

contained, nor shall any custom or practice which may grow up between the
parties in the

                                      37
<PAGE>

administration of the terms hereof be deemed a waiver of or in any way affect
the right of Landlord to insist upon the performance by Tenant in strict
accordance with said terms.  The subsequent acceptance of Rent hereunder by
Landlord shall not be deemed to be a waiver of any preceding breach by Tenant of
any term, covenant or condition of this Lease, other than the failure of Tenant
to pay the particular Rent so accepted, regardless of Landlord's knowledge of
such preceding breach at the time of acceptance of such Rent.

     (v)  Communications Equipment.  Subject to Landlord and Tenant agreeing on
          ------------------------
a reasonably monthly fee for the use thereof, Tenant, at its sole cost and
expense, shall have the non-exclusive right (it being understood that Landlord

of any rights which are granted after Tenant has installed its Dish do not
interfere with the rights granted to Tenant hereunder) to install, maintain, and

that all installation, construction and maintenance shall be performed in a
neat, responsible, and workmanlike manner, using generally acceptable
construction standards, consistent with such reasonable requirements as shall be
imposed by Landlord. Tenant further agrees to label each cable or wire placed by
Tenant in the telecommunications pathways of the Building, with identification
information as required by Landlord.  Tenant shall repair any damage to the
Building caused by Tenant's installation, maintenance, replacement, use or
removal of the Dish.  The Dish shall remain the property of Tenant, and Tenant
may remove the Dish at its cost at any time during the Term.  Tenant shall
remove the Dish at Tenant's cost and expense upon the expiration or termination
of this Lease.  Tenant agrees that the Dish, and any wires, cables or
connections relating thereto, and the installation, maintenance and operation
thereof shall in no way interfere with the use and enjoyment of the Building, or
the operation of communications (including, without limitation, other satellite
dishes) or computer devices by Landlord or by other tenants or occupants of the
Newport Corporate Center. If such interference shall occur, Landlord shall give
Tenant written notice thereof and Tenant shall correct the same within twenty-
four (24) hours of receipt of such notice. Landlord reserves the right to
disconnect power to any Dish if Tenant fails to correct such interference within
twenty-four (24) hours after such notice.  Landlord makes no warranty or
representation that the Building or any portions thereof are suitable for the
use of a Dish, it being assumed that Tenant has satisfied itself thereof.
Tenant shall protect, defend, indemnify and hold harmless Landlord from and
against claims, damages, liabilities, costs and expenses of every kind and

installation and construction of said data center and uninterrupted power supply
shall be in accordance with Section 25 hereof.

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

This exhibit is a continuation of that certain Lease dated February 17, 2000,
between Bentall Newport Centre L.L.C., a Washington limited liability company
and Mercata, Inc., a Delaware corporation on real property in King County,
Washington, and by this reference shall become part of that agreement.

This Work Letter Agreement is entered into upon the date this Lease is fully
executed by and between Landlord and Tenant.

                                   RECITALS

     A.   Concurrently with the execution of this Work Letter Agreement,
Landlord and Tenant have entered into a lease (the "Lease") covering certain
premises (the "Premises") more particularly described in the Lease.

     B.   In order to induce Tenant to enter into the Lease (which is hereby
incorporated by reference to the extent that the provisions of this Work Letter
Agreement may apply thereto) and in consideration of the mutual covenants herein
after contained, Landlord and Tenant hereby agree:

     1.   Space Plan and Related Requirements.
          -----------------------------------

          (a)  Landlord and Tenant have agreed upon standard Building
specifications (the "Uniform Building Specifications") for the tenant
improvements to be constructed in the Premises.  The Uniform Building
Specifications are attached hereto as Exhibit "C-2".  On or before February 25,
                                      ------------
2000, Tenant shall submit to Landlord for its review and approval a proposed,
preliminary space plan (the "Space Plan") for the Tenant Improvements to be
constructed on the Third Floor showing the location of demising walls,
partitions, doors, electrical devices, communication devices and indicating  in
general, the improvements to be done in Premises pursuant to this Work Letter
Agreement (which improvements are hereafter referred to as the "Tenant
Improvements").  The Preliminary Space Plan shall be attached to this Lease as
"Exhibit C-1".  Tenant shall submit a preliminary Space Plan for the Second
 -----------
Floor on or before a date which is three (3) months prior to the Second Floor
Delivery Date.  Tenant shall submit a preliminary Space Plan for the Expansion
Space on or before a date which is three (3) months prior to the Expansion Space
Availability Date.  The term "Tenant Improvements" shall include the tenant
improvements to be installed in the Second Floor and Expansion Space.

          (b)  Within seven (7) calendar days following the date Tenant submits
the preliminary Space Plan to Landlord, Tenant shall approve the preliminary
Space Plan and shall furnish to Landlord any final adjustments to the
preliminary Space Plan, including final location of partitions, doors, ceiling
devices, and final specifications for materials and finishes, electrical
devices, electrical loads, heat loads, extraordinary floor loads, special
equipment and all other requirements (all of which must be in conformance with
the Uniform Building Specifications).   Final adjustments to the preliminary
Space Plan shall not materially change the defined scope of the Tenant
Improvements set forth in Exhibit "C-1" attached hereto.  Any increases in cost
                          ------------
due to Tenant's changes not covered by the Tenant Improvement Allowance shall be
paid for by Tenant as Additional Rent.  Tenant agrees to meet and cooperate with
Landlord's architects and engineers and provide complete information as
requested.  Landlord shall be entitled, in all respects, to rely upon
information so supplied by Tenant's Representative (defined below). If Tenant
does not provide Landlord with any adjustments to the preliminary Space Plan
within the seven (7) day period referenced above, the preliminary Space Plan
attached hereto as Exhibit "C-1" shall be the final Space Plan.
                   ------------

          (c)  All space plans and related requirements referred to herein above
shall be subject to Landlord's prior approval, which approval shall not be
unreasonably withheld, unreasonably conditioned or unreasonably delayed, except
to the extent there are variations from the Uniform Building Specifications, in
which case Landlord may withhold its approval in Landlord's sole discretion.

                                      48
<PAGE>

          (d)  Tenant shall be allowed up to a maximum of three (3) adjustments
to the preliminary Space Plan.  Any adjustments beyond the first three (3) shall
be at Tenant's sole cost and expense.

          (e)  Landlord appoints Sam Buckingham ("Landlord's Representative") to
act for Landlord in all matters associated with this Work Letter Agreement.
Tenant appoints Laurel Vanek of TenantWorks ("Tenant's Representative") to act
for Tenant in all matters associated with this Work Letter Agreement.  All
inquiries, requests, instructions, authorizations and other communications with
respect to the matters covered by this Work Letter Agreement will be made to
Landlord's Representative or Tenant's Representative, as the case may be.
Neither party will make any inquiries of or requests to, and neither party will
give any instructions or authorizations to, any employee or agent of the other
party, including without limitation Tenant's architect, engineers and
contractors working at the Building, or any of their agents or employees, with
regard to matters associated with this Work Letter Agreement without providing
notice of the same to the respective Landlord's Representative or Tenant's
Representative.  Either party may change its Representative at any time by
providing three (3) days' prior written notice to the other party of the name,
address, and contact numbers of the new Representative.

     2.   Work Schedule.
          -------------

          Provided Tenant does not delay in providing any final adjustments to
the Space Plan within the time period described in subsection 1(b) above, then
within ten (10) business days following the date Landlord receives the Space
Plan with any final adjustments, Landlord shall provide Tenant with a
preliminary work schedule (the "Preliminary Work Schedule") setting forth the
various items of work and duration of each task.

     3.   Construction Drawings and Specifications.
          ----------------------------------------

          (a)  Within five (5) business days of Tenant's approval of the final
Space Plan, Tenant shall cause its architects and engineers to prepare the
initial set of construction drawings and specifications (the "Construction
Drawings") detailing the complete scope of the Tenant Improvements (the "Work")
based on the approved Space Plan.  The Construction Drawings shall include
architectural, structural, plumbing, mechanical, electrical, and fire protection
drawings as required and shall be prepared by duly licensed or registered
architects as required by regulatory agencies, and shall utilize the Uniform
Building Specifications.  Any additional drawings or revisions shall be at
Tenant's sole cost and expense.

          (b)  Tenant and Landlord shall approve Construction Drawings in
writing within five (5) business days from their completion, such approval not
to be unreasonably withheld, unreasonably conditioned or unreasonably delayed.
If neither party disapproves of the Construction Drawings within such five (5)
business day period, approval shall be deemed granted. If either party
disapproves of the Construction Drawings, Landlord shall cause the drawings to
be corrected within five business (5) days. After final approval, no further
changes may be made to the Construction Drawings without the prior written
approval of Tenant and Landlord, which approval not to be unreasonably withheld,
unreasonably conditioned or unreasonably delayed. Additional revisions requested
by the Tenant resulting in additional costs shall be the sole responsibility of
the Tenant. Approval of Construction Drawings shall be considered final
authorization to proceed.

          (c)  Landlord shall cause approved Construction Drawings to be
submitted to the appropriate governmental agencies for plan review and building
permit and attached to this Lease as Exhibit "C-3."  Revisions which may be
                                     ------------
required by governmental agencies as a result of the plan review process shall
be reviewed by Tenant and Landlord and modifications reflecting same shall be
mutually agreed upon in a timely manner so as not to delay progress of the Work.
The final work schedule and Substantial Completion date shall be extended as
required to reflect time lost, if any, to incorporate any such revisions.

          (d)  Tenant shall be allowed up to a maximum of three (3) adjustments
to the approved Construction Drawings.  Any adjustments beyond the first three
(3) shall be at Tenant's sole cost and expense.

                                                                     EXHIBIT "C"

<PAGE>

     4.   Construction of Tenant Improvements.
          -----------------------------------

          After the Construction Drawings have been prepared and approved,
Landlord shall submit for a building permit for the Tenant Improvements.
Landlord shall obtain three (3) competitive bids, on an open book basis, from
Landlord's preferred contractor list.  Landlord and Tenant shall approve one (1)
bid within three (3) days from Landlord's notice to Tenant of the bids.  Upon
approval, Landlord shall enter into a construction contract with its contractor
for the installation of Tenant Improvements in accordance with the Construction
Drawings.  The construction contract shall be a guaranteed maximum price
contract and shall not be signed until approved by Tenant, which approval shall
not be unreasonably withheld, unreasonably conditioned or unreasonably delayed.
Landlord shall include a provision in its contracts with the contractors and
subcontractors who perform the Work that Tenant is a direct third party
beneficiary of all warranties provided to Landlord.  All such warranties shall
be for the longest period the Landlord can obtain.  Within five (5) business
days from the date Landlord enters into the construction contract Landlord shall
obtain from the contractor a final work schedule (the "Final Work Schedule")
which shall replace the Preliminary Work Schedule.  Landlord shall supervise the
completion of the Work and shall use its reasonable best efforts to secure
completion of the Work by the date which is forty-five (45) days after the Third
Floor Availability Date provided that Tenant meats all required time lines and
such completion date is reasonably possible.  Tenant shall pay to Landlord a fee
for overhead and coordination of the Work equal to two percent (2%) of the gross
value (less any sales taxes and other amounts paid by Tenant directly to any
vendor) of the amount of the general contractor's final application for payment
related to such Work.  The scope of the services provided by Landlord shall
include without limitation the services listed on Exhibit "C-4".
                                                  ------------


     5.   Payment for Tenant Improvements.
          -------------------------------

     (a)  Landlord shall provide Tenant with an allowance of up to  $14.00 per
usable square foot of space on the Second Floor and $10.00 per useable square
foot of space on the Third Floor (the "Tenant Improvement Allowance") towards
the cost of the installation of the Tenant Improvements excluding Tenant's

(vi) delay of the Final Work Schedule. Upon written approval thereof by Tenant,
Landlord shall authorize its contractor, architect, engineer and/or vendor to
proceed with the Additional Work, and to submit actual costs by Change Order to
the construction contract for invoicing to Tenant. Failure by Tenant to approve

defined prior to such Change Order. Under no circumstances shall the Substantial
Completion Date or the Rent Commencement Date change as a result of Tenant's
Additional Work.

          (b)  Tenant shall pay to Landlord a fee for overhead and coordination

sales taxes and other amounts paid by Tenant directly to any vendor) of the
amount of the general contractor's final application for payment related to such
Additional Work.

          (c)  Tenant shall utilize Uniform Building Specifications as defined
in Exhibit "C-2" to the extent such finishes and materials are applicable to the
   ------------
scope of the Additional Work.  Tenant shall be responsible for all costs related
to the proper design, operation and maintenance of the Additional Work whether
or not installed by Landlord's contractor at Tenant's request.

          (d)  All Additional Work referred to herein above shall be subject to
Landlord's approval, which approval shall not be unreasonably withheld,
conditioned or delayed.

     7.   Substantial Completion and Commencement of Term.

Landlord's work as described in this Work Letter Agreement is substantially
complete, except for punch list items, Additional Work and/or Change Orders, and
a temporary certificate of occupancy for the Premises has been issued.

          (b)  Notwithstanding the provisions of Paragraph 6(a) above, if there

               i)   Tenant's failure to approve any item or to perform any other
obligation by the date specified in the Work Letter;

               ii)  Tenant's request for materials, finishes or methods of
construction not readily available; or

               iii) Tenant's request for Additional Work (whether or not
agreeable to Landlord),

such a delay shall cause the Commencement Date to accelerate by the number of
days delayed from the date the Commencement Date would otherwise have occurred.

          (c)  Within three (3) days prior to the date Landlord anticipates
delivering the Premises to Tenant, Tenant will conduct a walk-through inspection
of the Premises with Landlord and prepare a punch list of items needing
additional work by Landlord.  Landlord will complete all reasonable punch list
items within a reasonably time after the walk-through inspection.  In addition,

     2.   Payment.  Purchaser encloses herewith its check payable to the Company
in the amount equal to the total purchase price of the shares indicated in
section 1 above.

     3.   Representations and Warranties of the Purchaser.  The Purchaser hereby
represents and warrants that:

          3.1  Requisite Power and Authority.  Purchaser has all necessary power
and authority under all applicable provisions of law to execute and deliver this
Agreement and to carry out its provisions.  All action on Purchaser's part
required for the lawful execution and delivery of this Agreement have been or
will be effectively taken prior to the closing of the Offering.  Upon their
execution and delivery, this Agreement will be a valid and binding obligation of
Purchaser, enforceable in accordance with their terms, except (a) as limited by
applicable bankruptcy, insolvency, reorganization, moratorium or other laws of
general application affecting enforcement of creditors' rights, and (b) general
principles of equity that restrict the availability of equitable remedies.

          3.2  Investment Representations.  Purchaser understands that the
Shares have not been registered under the Securities Act of 1933, as amended
(the "Act").  Purchaser also understands that the Shares are being offered and
sold pursuant to an exemption from registration contained in the Act based in
part upon Purchaser's representations contained in the Agreement.  Purchaser
hereby represents and warrants as follows:

               (a)  Acquisition Entirely for Own Account. Purchaser is acquiring
the Shares for Purchaser's own account for investment only, not as a nominee or
agent, and not with a view to the resale or distribution of any part thereof,
and Purchaser has no present intention of selling, granting any participation
in, or otherwise distributing the same. By executing this Agreement, the
Purchaser further represents that the Purchaser does not have any contract,
undertaking, agreement or arrangement with any person to sell, transfer or grant
participation to such person or to any third person, with respect to any of the
Shares.

               (b)  Disclosure of Information.  Purchaser has received all the
information it considers necessary or appropriate for deciding whether to
purchase the Shares. The Purchaser further represents that it has had an

that it is capable

                                       1.
<PAGE>

of evaluating the merits and risks of the investment in the Company and has the
capacity to protect its own interest in connection with the transactions
contemplated in this Agreement. Purchaser understands that it must bear the
economic risk of this investment indefinitely unless the Shares are registered
pursuant to the Act, or an exemption from registration is available. Purchaser
understands that the Company has no present intention of registering the Shares
or any shares of its Common Stock. Purchaser also understands that there is no
assurance that any exemption from registration under the Act will be available
and that, even if available, such exemption may not allow Purchaser to transfer
all or any portion of the Shares under the circumstances, in the amounts or at
the times Purchaser might propose. Further, Purchaser is aware of no publication
of any advertisement in connection with the transactions contemplated in this
Agreement. Purchaser also represents it has not been organized for the purpose
of acquiring the Shares.

               (d)  Accredited Purchaser. Purchaser is an accredited purchaser
within the meaning of Regulation D under the Act.

               (e)  Restricted Securities. Purchaser understands that the Shares
may not be sold, transferred, or otherwise disposed of without registration
under the Act or an exemption therefrom, and that in the absence of an effective
registration statement covering the Shares or an available exemption from
registration under the Act, the Shares must be held indefinitely. In particular,
each Purchaser is aware of the provisions of Rule 144 promulgated under the Act
that the Shares may not be sold pursuant to Rule 144 unless all of the
conditions of that Rule are met. Among the conditions for use of Rule 144 may be
the availability of certain current information to the public about the Company.

make such information available.

the Shares are subject to restrictions on transfer.

     4.   Counterparts.  This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

                                       2.

understanding and agreement between the parties with regard to the subjects
hereof and no party shall be liable or bound to any other in any manner by any
representations, warranties, covenants and agreements except as specifically set

material adverse effect on the Company or its business.

except as may be granted pursuant to the Related Agreements, there are no
outstanding options, warrants, rights (including conversion or preemptive rights

and non-assessable, and will be free of any liens or encumbrances; provided,
however, that the Shares and the Conversion Shares may be subject to
restrictions on transfer under state and/or federal securities laws as set forth
herein or as otherwise required by such laws at the time a transfer is proposed.

Notes pursuant hereto and the Conversion Shares pursuant to the Notes and the
Restated Charter has been taken or will be taken prior to the Closing.  The
Agreement, the Notes and the Related Agreements, when executed and delivered,
will be valid and binding obligations of the Company enforceable in accordance
with their terms, except (a) as limited by applicable bankruptcy, insolvency,
reorganization, moratorium or other laws of general application affecting
enforcement of creditors' rights, (b) general principles of equity that restrict
the availability of equitable remedies, and (c) to the extent that the
enforceability of the indemnification provisions in Section 2.9 of the Investor
Rights Agreement may be limited by applicable laws.  The sale of the Shares and

(other than such contracts as relate to any such person's ownership of capital
stock or other securities of the Company).  Except as may be disclosed in the
Financial Statements, the Company is not a guarantor or indemnitor of any
indebtedness of any other person, firm or corporation.

          3.9  Changes. Since the Statement Date, there has not been:

               (a)  Any change in the assets, liabilities, financial condition
or operations of the Company from that reflected in the Financial Statements,

adverse effect on such assets, liabilities, financial condition, operations or
prospects of the Company;

               (b)  Any resignation or termination of any officer or key

business, assets, liabilities, financial condition, operations or prospects of
the Company;

               (m)  Any other event or condition of any character that, either

and marketable title to its properties and assets, including the properties and
assets reflected in the most recent balance sheet included in the Financial
Statements, and good title to its leasehold estates, in each case subject to no
mortgage, pledge, lien, lease, encumbrance or charge, other than (a) those
resulting from taxes which have not yet become delinquent, (b) minor liens and
encumbrances which do not materially detract from the value of the property
subject thereto or materially impair the operations of the Company, and (c)
those that have otherwise arisen in the ordinary course of business.  All
facilities, machinery, equipment, fixtures, vehicles and other properties owned,
leased or used by the Company are in good operating condition and repair and are
reasonably fit and usable for the purposes for which they are being used.  The
Company is in compliance with all material terms of each lease to which it is a
party or is otherwise bound.

          3.11 Patents and Trademarks.  To the best of its knowledge, the
Company owns or possesses sufficient legal rights to all patents, trademarks,
service marks, trade names, copyrights, trade secrets, licenses, information and
other proprietary rights and processes necessary for its business as now
conducted and as presently proposed to be conducted, without any known
infringement of the rights of others.  There are no outstanding options,
licenses or

                                      6.
<PAGE>

agreements of any kind relating to the foregoing, nor is the Company bound by or
a party to any options, licenses or agreements of any kind with respect to the
patents, trademarks, service marks, trade names, copyrights, trade secrets,
licenses, information and other proprietary rights and processes of any other
person or entity other than such licenses or agreements arising from the
purchase of "off the shelf" or standard products. The Company has not received
any communications alleging that the Company has violated or, by conducting its
business as presently proposed, would violate any of the patents, trademarks,
service marks, trade names, copyrights or trade secrets or other proprietary
rights of any other person or entity. The Company is not aware that any of its
employees is obligated under any contract (including licenses, covenants or
commitments of any nature) or other agreement, or subject to any judgment,
decree or order of any court or administrative agency, that would interfere with
their duties to the Company or that would conflict with the Company's business
as presently proposed to be conducted. Neither the execution nor delivery of
this Agreement or the Related Agreements, nor the carrying on of the Company's
business by the employees of the Company, nor the conduct of the Company's
business as presently proposed, will, to the Company's knowledge, conflict with
or result in a breach of the terms, conditions or provisions of, or constitute a
default under, any contract, covenant or instrument under which any employee is
now obligated. The Company does not believe it is or will be necessary to
utilize any inventions, trade secrets or proprietary information of any of its
employees made prior to their employment by the Company, except for inventions,
trade secrets or proprietary information that have been assigned to the Company.

          3.12 Compliance with Other Instruments.  The Company is not in
violation or default of any term of its Restated Charter or Bylaws, or, to the
Company's knowledge, of any provision of any mortgage, indenture, contract,
agreement, instrument or contract to which it is party or by which it is bound
or of any judgment, decree, order, or writ.  The execution, delivery, and
performance of and compliance with this Agreement, the Notes and the Related
Agreements, and the issuance and sale of the Shares pursuant hereto and of the
Conversion Shares and the Notes pursuant to the Notes and Restated Charter, will
not, with or without the passage of time or giving of notice, result in any such
material violation, or be in conflict with or constitute a default under any
such term, or result in the creation of any mortgage, pledge, lien, encumbrance
or charge upon any of the properties or assets of the Company or the suspension,
revocation, impairment, forfeiture or non-renewal of any permit, license,
authorization or approval applicable to the Company, its business or operations
or any of its assets or properties.

          3.13 Litigation. There is no action, suit, proceeding or investigation
pending or to the Company's knowledge currently threatened in writing against
the Company that questions the validity of this Agreement, the Notes or the
Related Agreements or the right of the Company to enter into any of such
agreements, or to consummate the transactions contemplated hereby or thereby, or
which might result, either individually or in the aggregate, in any material
adverse change in the assets, condition, affairs or prospects of the Company,
financially or otherwise, or any change in the current equity ownership of the
Company, nor is the Company aware that there is any basis for any of the
foregoing.  The foregoing includes, without limitation, actions pending or
threatened in writing (or any basis therefor known to the Company) involving the
prior employment of any of the Company's employees, their use in connection with
the Company's business of any information or techniques allegedly proprietary to
any of their former employers, or their obligations under any agreements with
prior employers.  The Company is not a party or

                                      7.
<PAGE>

subject to the provisions of any order, writ, injunction, judgment or decree of
any court or government agency or instrumentality. There is no action, suit,
proceeding or investigation by the Company currently pending or which the
Company intends to initiate.

          3.14 Tax Returns and Payments. The Company has filed all tax returns
(federal, state and local) required to be filed by it.  All taxes shown to be
due and payable on such returns, any assessments imposed, and all other taxes
due and payable by the Company on or before the Closing, have been paid or will
be paid prior to the time they become delinquent.  The Company has not been
advised (a) that any of its returns, federal, state or other, have been or are
being audited as of the date hereof, or (b) of any deficiency in assessment or
proposed judgment to its federal, state or other taxes.  The Company has no
knowledge of any liability for any tax to be imposed upon its properties or
assets as of the date of this Agreement that is not adequately provided for.

          3.15 Employees. The Company has no collective bargaining agreements
with any of its employees.  There is no labor union organizing activity pending
or, to the Company's knowledge, threatened with respect to the Company.  To the
Company's knowledge, no employee of the Company, nor any consultant with whom
the Company has contracted, is in violation of any term of any employment
contract, proprietary information agreement or any other agreement relating to
the right of any such individual to be employed by, or to contract with, the
Company because of the nature of the business to be conducted by the Company;
and to the Company's knowledge the continued employment by the Company of its
present employees, and the performance of the Company's contracts with its
independent contractors, will not result in any such violation.  The Company has
not received any notice alleging that any such violation has occurred.  No
employee of the Company has been granted the right to continued employment by
the Company or to any material compensation following termination of employment
with the Company.  The Company is not aware that any officer or key employee, or
that any group of key employees, intends to terminate his, her or their
employment with the Company, nor does the Company have a present intention to
terminate the employment of any officer, key employee or group of key employees.

          3.16 Proprietary Information and Inventions Agreements. Each employee,
officer and consultant of the Company has executed a Proprietary Information and
Inventions Agreement in the form of Exhibit H attached hereto.  No current
employee, officer or consultant of the Company has excluded works or inventions
made prior to his or her employment with the Company from his or her assignment
of inventions pursuant to such employee, officer or consultant's Proprietary
Information and Inventions Agreement.

          3.17 Registration Rights and Voting Rights.

               (a)  Except as required pursuant to the Investor Rights
Agreement, the Company is presently not under any obligation, and has not
granted any rights, to register (as defined in Section 1.1 of the Investor
Rights Agreement) any of the Company's presently outstanding securities or any
of its securities that may hereafter be issued.

                                      8.
<PAGE>

               (b)  Except as provided for in the Voting Agreement, to the
Company's knowledge, no shareholder of the Company has entered into any
agreement with respect to the voting of equity securities of the Company.

          3.18 Compliance with Laws; Permits.  To its knowledge, the Company is
not in violation of any applicable statute, rule, regulation, order or
restriction of any domestic or foreign government or any instrumentality or
agency thereof in respect of the conduct of its business or the ownership of its
properties which violation would materially and adversely affect the business,
assets, liabilities, financial condition, operations or prospects of the
Company.  No governmental orders, permissions, consents, approvals or
authorizations are required to be obtained and no registrations or declarations
are required to be filed in connection with the execution and delivery of this
Agreement and the issuance of the Shares, the Notes or the Conversion Shares,
except such as has been duly and validly obtained or filed, or with respect to
any filings that must be made after the Closing, as will be filed in a timely
manner.  The Company has all franchises, permits, licenses and any similar
authority necessary for the conduct of its business as now being conducted by
it, the lack of which could materially and adversely affect the business,
properties, prospects or financial condition of the Company and believes it can
obtain, without undue burden or expense, any similar authority for the conduct
of its business as planned to be conducted.

          3.19 Offering Valid. Assuming the accuracy of the representations and
warranties of the Purchasers contained in Section 4.2 hereof, the offer, sale
and issuance of the Shares, the Notes and the Conversion Shares will be exempt
from the registration requirements of the Securities Act of 1933, as amended
(the "Securities Act"), and will have been registered or qualified (or are
exempt from registration and qualification) under the registration, permit or
qualification requirements of all applicable state securities laws.  Neither the
Company nor any agent on its behalf has solicited or will solicit any offers to
sell or has offered to sell or will offer to sell all or any part of the Shares
or the Notes to any person or persons so as to bring the sale of such Shares by
the Company within the registration provisions of the Securities Act or any
state securities laws.

          3.20 Full Disclosure. The Company has provided the Purchasers with all
information requested by the Purchasers in connection with their decision to
purchase the Shares and/or the Notes, including all information the Company
believes is reasonably necessary to make such investment decision.  To the
Company's knowledge, neither this Agreement, the Exhibits hereto, the Related
Agreements nor any other document delivered by the Company to Purchasers or
their attorneys or agents in connection herewith or therewith or with the
transactions contemplated hereby or thereby, contain any untrue statement of a
material fact nor, to the Company's knowledge, omit to state a material fact
necessary in order to make the statements contained herein or therein not
misleading.

          3.21 Insurance. The Company has fire and casualty insurance policies
with coverage customary for companies similarly situated to the Company.

     4.   Representations And Warranties Of The Purchasers.

          Each Purchaser hereby represents and warrants to the Company as
follows (such representations and warranties do not lessen or obviate the
representations and warranties of the Company set forth in this Agreement):

          4.1  Requisite Power and Authority. Purchaser has all necessary power
and authority under all applicable provisions of law to execute and deliver this
Agreement, the Notes (if applicable) and the Related Agreements and to carry out
their provisions.  All action on Purchaser's part required for the lawful
execution and delivery of this Agreement, the Notes (if applicable) and the
Related Agreements have been or will be effectively taken prior to the Closing.
Upon their execution and delivery, this Agreement, the Notes (if applicable) and
the Related Agreements will be valid and binding obligations of Purchaser,
enforceable in accordance with their terms, except (a) as limited by applicable
bankruptcy, insolvency, reorganization, moratorium or other laws of general
application affecting enforcement of creditors' rights, (b) general principles
of equity that restrict the availability of equitable remedies, and (c) to the
extent that the enforceability of the indemnification provisions of Section 2.9
of the Investor Rights Agreement may be limited by applicable laws.

          4.2  Investment Representations. Purchaser understands that neither
the Shares, the Notes nor the Conversion Shares have been registered under the
Securities Act.  Purchaser also understands that the Shares and the Notes are
being offered and sold pursuant to an exemption from registration contained in
the Securities Act based in part upon Purchaser's representations contained in
this Agreement.  Purchaser hereby represents and warrants as follows:

               (a)  Purchaser Bears Economic Risk. Purchaser has substantial
experience in evaluating and investing in private placement transactions of
securities in companies similar to the Company so that it is capable of
evaluating the merits and risks of its investment in the Company and has the
capacity to protect its own interests. Purchaser must bear the economic risk of
this investment indefinitely unless the Shares (or the Notes or the Conversion
Shares) are registered pursuant to the Securities Act, or an exemption from
registration is available. Purchaser understands that the Company has no present
intention of registering the Shares, the Notes, the Conversion Shares or any
shares of its Common Stock. Purchaser also understands that there is no
assurance that any exemption from registration under the Securities Act will be
available and that, even if available, such exemption may not allow Purchaser to
transfer all or any portion of the Shares, the Notes or the Conversion Shares
under the circumstances, in the amounts or at the times Purchaser might propose.

               (b)  Acquisition for Own Account. Purchaser is acquiring the
Shares, the Notes (if applicable) and the Conversion Shares for Purchaser's own
account for investment only, and not with a view towards their distribution.

               (c)  Purchaser Can Protect Its Interest. Purchaser represents
that by reason of its, or of its management's, business or financial experience,
Purchaser has the capacity to protect its own interests in connection with the
transactions contemplated in this Agreement,

                                      10.
<PAGE>

and the Related Agreements. Further, Purchaser is aware of no publication of any
advertisement in connection with the transactions contemplated in the Agreement.

               (d)  Accredited Investor. Purchaser represents that it is an
accredited investor within the meaning of Regulation D under the Securities Act.

               (e)  Company Information. Purchaser has received and read the
Financial Statements and has had an opportunity to discuss the Company's
business, management and financial affairs with directors, officers and
management of the Company and has had the opportunity to review the Company's
operations and facilities. Purchaser has also had the opportunity to ask
questions of and receive answers from, the Company and its management regarding
the terms and conditions of this investment.

               (f)  Rule 144. Purchaser acknowledges and agrees that the Shares,
the Notes and, if issued, the Conversion Shares must be held indefinitely unless
they are subsequently registered under the Securities Act or an exemption from
such registration is available. Purchaser has been advised or is aware of the
provisions of Rule 144 promulgated under the Securities Act as in effect from
time to time, which permits limited resale of shares purchased in a private
placement subject to the satisfaction of certain conditions, including, among
other things: the availability of certain current public information about the
Company, the resale occurring following the required holding period under Rule
144 and the number of shares being sold during any three-month period not
exceeding specified limitations.

               (g)  Residence. If the Purchaser is an individual, then the
Purchaser resides in the state or province identified in the address of the
Purchaser set forth on Exhibit A; if the Purchaser is a partnership,
corporation, limited liability company or other entity, then the office or
offices of the Purchaser in which its investment decision was made is located at
the address or addresses of the Purchaser set forth on Exhibit A.

          4.3  Transfer Restrictions. Each Purchaser acknowledges and agrees
that the Shares and, if issued, the Conversion Shares are subject to
restrictions on transfer as set forth in the Investor Rights Agreement.

     5.   Conditions To Closing.

          5.1  Conditions to Purchasers' Obligations at the Closing. Purchasers'

               (b)  Consents, Permits, and Waivers. The Company shall have

          6.6  Amendment and Waiver.

               (a)  This Agreement may be amended or modified only upon the
written consent of the Company and holders of at least a majority of the Shares
(treated as if converted and including any Conversion Shares into which the
Shares have been converted that have not been sold to the public).

               (b)  The obligations of the Company and the rights of the holders
of the Shares and the Conversion Shares under the Agreement may be waived only
with the written consent of the holders of at least a majority of the Shares
(treated as if converted and including any Conversion Shares into which the
Shares have been converted that have not been sold to the public).

               (c)  Notwithstanding the foregoing, this Agreement may be amended

exercise any right, power or remedy accruing to any party, upon any breach,
default or noncompliance  by another party under this Agreement, the Related
Agreements or the Restated Charter, shall impair any such right, power or
remedy, nor shall it be construed to be a waiver of any such breach, default or
noncompliance, or any acquiescence therein, or of or in any similar breach,
default or noncompliance thereafter occurring. It is further agreed that any
waiver, permit, consent or approval of any kind or character on any Purchaser's

          6.8  Waiver of Conflicts.  Each party to this Agreement acknowledges
that Cooley Godward LLP ("Cooley Godward"), outside general counsel to the
Company, has in the past performed and is or may now or in the future represent
one or more of the Purchasers or their affiliates in matters unrelated to the
transactions contemplated by this Agreement (the "Financing"), including
representation of such Purchasers or their affiliates in matters of a similar
nature to the Financing.   The applicable rules of professional conduct require
that Cooley Godward inform the parties hereunder of this representation and
obtain their consent.  Cooley Godward has served as outside general counsel to
the Company and has negotiated the terms of the Financing solely on behalf of
the Company.  It is the belief of Cooley Godward that these terms and conditions
represent an arm's length transaction between the Company and the Purchasers.
Purchasers have been represented by independent legal counsel regarding the
terms of the Financing.  The Company and each Purchaser hereby (a) acknowledge
that they have had an opportunity to ask for and have obtained information
relevant to such representation, including disclosure of the reasonably
foreseeable adverse consequences of such representation; (b) acknowledge that
with respect to the Financing, Cooley Godward has represented solely the
Company, and not any Purchaser or any stockholder, director or employee of the
Company or any Purchaser; and (c) gives its informed consent to Cooley Godward's
representation the Company  in the Financing.

          6.9  Notices. All notices required or permitted hereunder shall be in
writing and shall be deemed effectively given: (a) upon personal delivery to the
party to be notified, (b) when sent by confirmed telex or facsimile if sent
during normal business hours of the recipient, if not, then on the next business
day, (c) five (5) days after having been sent by registered or certified mail,
return receipt requested, postage prepaid, or (d) one (1) day after deposit with
a nationally recognized overnight courier, specifying next day delivery, with
written verification of receipt.  All communications shall be sent to the
Company at the address as set forth on the signature page hereof and to
Purchaser at the address set forth on Exhibit A attached hereto or at such other
address as the Company or Purchaser may designate by ten (10) days advance
written notice to the other parties hereto.

          6.10 Expenses.  The Company shall pay all costs and expenses that it
incurs with respect to the negotiation, execution, delivery and performance of
the Agreement.  The Company shall, at the Closing, reimburse the reasonable fees
of and expenses of one special counsel for the Purchasers, not to exceed
$15,000, incurred in connection with the negotiation, execution, delivery and
performance of this Agreement.

          6.11 Attorneys' Fees. In the event that any suit or action is
instituted to enforce any provision in this Agreement, the prevailing party in
such dispute shall be entitled to recover from the losing party all fees, costs
and expenses of enforcing any right of such prevailing party under or with
respect to this Agreement, including without limitation, such reasonable fees
and expenses of attorneys and accountants, which shall include, without
limitation, all fees, costs and expenses of appeals.

          6.12 Titles and Subtitles. The titles of the sections and subsections
of the Agreement are for convenience of reference only and are not to be
considered in construing this Agreement.

                                      15.
<PAGE>

          6.13 Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be an original, but all of which together
shall constitute one instrument.

          6.14 Broker's Fees. Each party hereto represents and warrants that no
agent, broker, investment banker, person or firm acting on behalf of or under
the authority of such party hereto is or will be entitled to any broker's or
finder's fee or any other commission directly or indirectly in connection with
the transactions contemplated herein.  Each party hereto further agrees to
indemnify each other party for any claims, losses or expenses incurred by such
other party as a result of the representation in this Section 6.14 being untrue.

          6.15 Exculpation Among Purchasers. Each Purchaser acknowledges that it
is not relying upon any person, firm, or corporation, other than the Company and
its officers and directors, in making its investment or decision to invest in
the Company.  Each Purchaser agrees that no Purchaser nor the respective
controlling persons, officers, directors, partners, agents, or employees of any
Purchaser shall be liable to any other Purchaser for any action heretofore or
hereafter taken or omitted to be taken by any of them in connection with the
Shares and Conversion Shares.

          6.16 Confidentiality. Each party hereto agrees that, except with the
prior written consent of the other party, it shall at all times keep
confidential and not divulge, furnish or make accessible to anyone any
confidential information, knowledge or data concerning or relating to the
business or financial affairs of the other parties to which such party has been
or shall become privy by reason of this Agreement or the Related Agreements,
discussions or negotiations relating to this Agreement or the Related
Agreements, the performance of its obligations hereunder or the ownership of the
Shares purchased hereunder.  The provisions of this Section 6.16 shall be in
addition to, and not in substitution for, the provisions of any separate
nondisclosure agreement executed by the parties hereto.

          6.17 Pronouns. All pronouns contained herein, and any variations
thereof, shall be deemed to refer to the masculine, feminine or neutral,
singular or plural, as to the identity of the parties hereto may require.

          6.18 California Corporate Securities Law. THE SALE OF THE SECURITIES
WHICH ARE THE SUBJECT OF THIS AGREEMENT HAS NOT BEEN QUALIFIED WITH THE
COMMISSIONER OF CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF SUCH
SECURITIES OR THE PAYMENT OR RECEIPT OF ANY PART OF THE CONSIDERATION THEREFOR
PRIOR TO SUCH QUALIFICATION OR IN THE ABSENCE OF AN EXEMPTION FROM SUCH
QUALIFICATION IS UNLAWFUL.  PRIOR TO ACCEPTANCE OF SUCH CONSIDERATION BY THE
COMPANY, THE RIGHTS OF ALL PARTIES TO THIS AGREEMENT ARE EXPRESSLY CONDITIONED
UPON SUCH QUALIFICATION BEING OBTAINED OR AN EXEMPTION FROM SUCH QUALIFICATION
BEING AVAILABLE.

                          CONVERTIBLE PROMISSORY NOTE


$_________.00                                              __________  ___, 1999
                                                            Bellevue, Washington

     For value received, Mercata, Inc., a Delaware corporation (the "Company"),
promises to pay to __________________________ (the "Holder"), the principal sum
of __________________ dollars ($________.00).  No interest shall accrue or be
paid on this Note; provided, that if this Note shall not have converted in
accordance with Section 2 below on or before November 30, 1999, this Note shall
bear interest accruing from the date hereof on the unpaid principal amount at a
rate equal to the lower of (a) 7.00% per annum, compounded annually or (b) the
highest rate permitted by law.  This Note is one of a series of Convertible
Promissory Notes containing substantially identical terms and conditions issued
pursuant to that certain Series B Preferred Stock Purchase Agreement, dated
September ____, 1999 (the "Purchase Agreement").  Such Notes are referred to
herein as the "Notes," and the holders thereof are referred to herein as the
"Holders."  This Note is subject to the following terms and conditions.

     1.   Maturity.  Unless converted as provided in Section 2, this Note will
automatically mature and be due and payable on November 30, 1999 (the "Maturity
Date").  Subject to Section 2 below, any interest shall accrue on this Note but
shall not be due and payable until the Maturity Date.

     2.   Conversion

          (a)  HSR Clearance.  As soon as practicable after the Closing (as
defined in the Purchase Agreement), the Company and the Holder hereby agree to
file or to cause to be filed with the United States Federal Trade Commission
(the "FTC") and the Antitrust Division of the United States Department of
Justice (the "DOJ") pursuant to the Hart-Scott-Rodino Antitrust Improvements Act
of 1976, as amended (the "HSR Act") all requisite documents and notifications in
order to provide for the conversion of this Note into shares of the Company's
Series B Preferred Stock. Upon the earlier of one business day after (i) the
date all required clearances or pre-termination notices under the HSR Act have
been received from the FTC and the DOJ (or all applicable waiting periods have
expired) or (ii) the date the Holder and the Company are no longer required by
law to make filings under the HSR to convert this Note into capital stock, the
entire principal amount of this Note shall automatically convert into fully-paid
and non-assessable shares of the Company's Series B Preferred Stock (the
"Stock"); provided,

                                      1.
<PAGE>

however, the automatic conversion of such principal amount into shares of the
Company's Series B Preferred Stock shall be conditioned upon (A) the Company
having provided to the Holder a compliance certificate in the form attached
hereto as Exhibit A or (B) the Holder having waived such applicable terms,
conditions or certifications included in such certificate, either individually
or in the aggregate. The number of shares of Stock to be issued upon such
conversion shall be equal to the quotient obtained by dividing (i) the entire
outstanding principal amount of this Note by (ii) $3.125 (as adjusted for any
future stock splits, stock dividends, recapitalizations or the like to the
Stock), provided that no fractional shares shall be issued. In the event that
the required clearances from the FTC and the DOJ are not obtained, this Note
shall not be convertible into the Stock.

          (b)  Redemption.  In the event the Company consummates a Liquidity
Event (as defined below) prior to the conversion of this note pursuant to
Section 2(a), then the Company shall redeem this Note for an aggregate
consideration substantially equivalent to the consideration which would have
been received by the Holder had the Note been converted into Series B Preferred
Stock immediately prior to the consummation of such Liquidity Event, as
determined in the reasonable and good faith judgement of the Board of Directors
of the Company. For the Purposes of hereof "Liquidity Event" shall mean (i) any
consolidation or merger of the Company with or into any other corporation or
other entity or person, or any other corporate reorganization, in which the
stockholders of the Company immediately prior to such consolidation, merger or
reorganization, own less than 50% of the Company's voting power immediately
after such consolidation, merger or reorganization, or any transaction or series
of related transactions to which the Company is a party in which in excess of
50% of the Company's voting power is transferred (ii) any voluntary or
involuntary liquidation or dissolution of the Company, or (iii) the sale of all
or substantially all the assets of the Company.

          (c)  Mechanics and Effect of Conversion.  No fractional shares of the
Company's capital stock will be issued upon conversion of this Note. In lieu of
any fractional share to which the Holder would otherwise be entitled, the
Company will pay to the Holder in cash the amount of the unconverted principal
and interest balance of this Note that would otherwise be converted into such
fractional share. Upon conversion of this Note pursuant to this Section 2, the
Holder shall surrender this Note, duly endorsed, at the principal offices of the
Company or any transfer agent of the Company. At its expense, the Company will,
as soon as practicable thereafter, issue and deliver to such Holder, at such
principal office, a certificate or certificates for the number of shares to
which such Holder is entitled upon such conversion, together with any other
securities and property to which the Holder is entitled upon such conversion
under the terms of this Note, including a check payable to the Holder for any
cash amounts payable as described herein. Upon conversion of this Note, the
Company will be forever released from all of its obligations and liabilities
under this Note with regard to that portion of the principal amount and accrued
interest being converted including without limitation the obligation to pay such
portion of the principal amount and accrued interest.

     3.   Payment.  All payments shall be made in lawful money of the United
States of America at such place as the Holder hereof may from time to time
designate in writing to the Company. Payment shall be credited first to the
accrued interest then due and payable and the

                                      2.
<PAGE>

remainder applied to principal. Prepayment of this Note may be made without
penalty, if the Company's Board of Directors has determined, in consultation
with legal counsel, and with the consent of the Holders of a majority of the
outstanding principal amount of the Notes, that the required clearances or pre-
termination notices under the HSR Act specified in Section 2(a) are not likely
to be obtained, otherwise this note made not prepaid without the consent of the
Holders of a majority of the outstanding principal amount of the Notes;
provided, however, that the Company may repay the Note on or after November 30,
1999 in the event the conditions to conversion set forth in Section 2 hereof
have not occurred.

     4.   Transfer; Successors and Assigns.  The terms and conditions of this
Note shall inure to the benefit of and be binding upon the respective successors
and assigns of the parties. Notwithstanding the foregoing, the Company may not
assign, pledge or otherwise transfer this Note without the prior written consent
of the Holder, which shall not be unreasonably withheld, and the Holder may not
assign, pledge, or otherwise transfer this Note without the prior written
consent of the Company, which shall not be unreasonably withheld. Subject to the
preceding sentence, this Note may be transferred only upon surrender of the
original Note for registration of transfer, duly endorsed, or accompanied by a
duly executed written instrument of transfer in form satisfactory to the Holder.
Thereupon, a new note for the same principal amount and interest will be issued
to, and registered in the name of, the transferee. Interest and principal are
payable only to the registered holder of this Note.

     5.   Governing Law.  This Note and all acts and transactions pursuant
hereto and the rights and obligations of the parties hereto shall be governed,
construed and interpreted in accordance with the laws of the State of
Washington, without giving effect to principles of conflicts of law.

     6.   Notices.  Any notice required or permitted by this Note shall be in
writing and shall be deemed sufficient upon delivery, when delivered personally
or one business day after being sent by a nationally-recognized overnight
delivery service (such as Federal Express or UPS), or forty-eight (48) hours
after being deposited in the U.S. mail, as certified or registered mail, with
postage prepaid, addressed to the party to be notified at such party's address
as set forth below or as subsequently modified by written notice.

     7.   Amendments and Waivers.  Any term of this Note may be amended only
with the written consent of the Company and at least a majority in interest of
the Holders. Any amendment or waiver effected in accordance with this Section 7
shall be binding upon the Company, the Holders and each transferee of the Notes.

     8.   Waiver.  The Company waives presentment and demand for payment, notice
of dishonor, protest and notice of protest of this Note, and shall pay all costs
of collection when incurred, including, without limitation, reasonable
attorneys' fees, costs and other expenses.

     The right to plead any and all statutes of limitations as a defense to any
demands hereunder is hereby waived to the full extent permitted by law.

     A.   This Corporation is authorized to issue two classes of stock to be
designated, respectively, "Common Stock" and "Preferred Stock."  The total
number of shares which the Corporation is authorized to issue is seventy million
(70,000,000) shares, forty million (40,000,000) shares of which shall be Common
Stock (the "Common Stock") and thirty million (30,000,000) shares of which shall
be Preferred Stock (the "Preferred Stock").  The Preferred Stock shall have a
par value of one tenth of a cent ($0.001) per share and the Common Stock shall
have a par value of one tenth of a cent ($0.001) per share.

                                      1.
<PAGE>

     B.   The number of authorized shares of Common Stock may be increased or
decreased (but not below the number of shares of Common Stock then outstanding)
by the affirmative vote of the holders of a majority of the stock of the
Corporation (voting together on an as-if-converted basis).

     C.   Fourteen million (14,000,000) of the authorized shares of Preferred
Stock are hereby designated "Series A Preferred Stock" and twelve million
(12,000,000) of the authorized shares of Preferred Stock are hereby designated
"Series B Preferred Stock" (collectively, the "Series Preferred").

     D.   The rights, preferences, privileges, restrictions and other matters
relating to the Series Preferred are as follows:

          1.   Dividend Rights.

               (a)  Holders of Series Preferred, in preference to the holders of
any other stock of the Company ("Junior Stock"), shall be entitled to receive,
when and as declared by the Board of Directors, but only out of funds that are
legally available therefor, cash dividends at the rate of eight percent (8%) of
the Original Issue Price (as defined below) per annum on each outstanding share
of Series Preferred (as adjusted for any stock dividends, combinations, splits,
recapitalizations and the like with respect to such shares). The "Original Issue
Price" of the Series A Preferred Stock and the Series B Preferred Stock shall be
one dollar and five cents ($1.05) per share and three dollars twelve and one-
half cents per share ($3.125), respectively. Such dividends shall be payable
only when, as and if declared by the Board of Directors and shall be non-
cumulative.

               (b)  So long as any shares of Series Preferred shall be
outstanding, no dividend, whether in cash or property, shall be paid or
declared, nor shall any other distribution be made, on any Junior Stock, nor
shall any shares of any Junior Stock of the Company be purchased, redeemed, or
otherwise acquired for value by the Company (except for acquisitions of Common
Stock by the Company pursuant to agreements which permit the Company to
repurchase such shares upon termination of services to the Company or in
exercise of the Company's right of first refusal upon a proposed transfer) until
all dividends (set forth in Section 1(a) above) on the Series Preferred shall
have been paid or declared and set apart. In the event dividends are paid on any
share of Common Stock, an additional dividend shall be paid with respect to all
outstanding shares of Series Preferred in an amount equal per share (on an as-
if-converted to Common Stock basis) to the amount paid or set aside for each
share of Common Stock. The provisions of this Section 1(b) shall not, however,
apply to (i) a dividend payable in Common Stock, (ii) the acquisition of shares
of any Junior Stock in exchange for shares of any other Junior Stock, or (iii)
any repurchase of any outstanding securities of the Company that is unanimously
approved by the Company's Board of Directors.

          2.   Voting Rights.

               (a)  General Rights.  Except as otherwise provided herein or as
required by law, the Series Preferred shall be voted equally with the shares of
the Common Stock

                                      2.
<PAGE>

of the Company and not as a separate class, at any annual or special meeting of
stockholders of the Company, and may act by written consent in the same manner
as the Common Stock, in either case upon the following basis: each holder of
shares of Series Preferred shall be entitled to such number of votes as shall be
equal to the whole number of shares of Common Stock into which such holder's
aggregate number of shares of Series Preferred are convertible (pursuant to
Section 4 hereof) immediately after the close of business on the record date
fixed for such meeting or the effective date of such written consent.

               (b)  Separate Vote of Series Preferred.  For so long as at least
ten million (10,000,000) shares of Series Preferred (subject to adjustment for
any stock split, reverse stock split or other similar event affecting the Series
Preferred) remain outstanding, in addition to any other vote or consent required
herein or by law, the vote or written consent of the holders of at least a
majority of the outstanding Series Preferred shall be necessary for effecting or
validating the following actions:

                    (i)     Any amendment, alteration, or repeal of any
provision of the Certificate of Incorporation or Bylaws of the Company
(including any filing of a Certificate of Designation), that alters or changes
the voting powers, preferences, or other special rights or privileges, or
restrictions of the Series Preferred (including by way of a merger or
consolidation).

                    (ii)    Any increase or decrease (other than by redemption
or conversion) in the authorized number of shares of Common Stock or Preferred
Stock;

                    (iii)   Any authorization or any designation, whether by
reclassification or otherwise, of any new class or series of stock or any other
securities convertible into equity securities of the Company ranking on a parity
with or senior to the Series Preferred in right of redemption, liquidation
preference, voting or dividends or any increase in the authorized or designated
number of any such new class or series;

                    (iv)    Any redemption, repurchase, payment of dividends or
other distributions with respect to Junior Stock (except for acquisitions of
Common Stock by the Company pursuant to agreements which permit the Company to
repurchase such shares upon termination of services to the Company or in
exercise of the Company's right of first refusal upon a proposed transfer);

                    (v)     Any agreement by the Company or its stockholders
regarding an Asset Transfer or Acquisition (each as defined in Section 3(c));

                    (vi)    Any action that results in the payment or
declaration of a dividend on any shares of Common Stock or Preferred Stock;

                    (vii)   Any voluntary dissolution or liquidation of the
Company; or

                    (viii)  Any increase or decrease in the authorized number of
members of the Company's Board of Directors.

                                      3.
<PAGE>

               (C)  Separate Votes of Series B Preferred Stock.  For so long as
at least five million (5,000,000) shares of Series B Preferred Stock (subject to
adjustment for any stock split, reverse stock split or other similar event
affecting the Series B Preferred Stock) remain outstanding, in addition to any
other vote or consent required herein or by law, the vote or written consent of
the holders of at least a majority of the outstanding Series B Preferred Stock
shall be necessary for effecting or validating the following actions:

                    (i)    Any amendment, alteration, or repeal of any provision
of the Certificate of Incorporation or Bylaws of the Company (including any
filing of a Certificate of Designation), that alters or changes the voting
powers, preferences, or other special rights or privileges, or restrictions of
the Series B Preferred Stock (including by way of a merger or consolidation).

                    (ii)   Any authorization or any designation, whether by
reclassification or otherwise, of any new class or series of stock or any other
securities convertible into equity securities of the Company ranking on a parity
with or senior to the Series B Preferred in right of redemption, liquidation
preference, voting or dividends or any increase in the authorized or designated
number of any such new class or series;

                    (iii)  Any redemption, repurchase, payment of dividends or
other distributions with respect to Junior Stock (except for acquisitions of
Common Stock by the Company pursuant to agreements which permit the Company to
repurchase such shares upon termination of services to the Company or in
exercise of the Company's right of first refusal upon a proposed transfer);

                    (iv)   Any agreement by the Company or its stockholders
regarding an Asset Transfer or Acquisition (each as defined in Section 3(c)).

               (d)  Election of Board of Directors.  For so long as at least ten
million (10,000,000) shares of Series Preferred remain outstanding (subject to
adjustment for any stock split, reverse stock split or similar event affecting
the Series Preferred) (i) the holders of Series A Preferred Stock, voting as a
separate class, shall be entitled to elect two (2) members of the Company's
Board of Directors at each meeting or pursuant to each consent of the Company's
stockholders for the election of directors, and to remove from office such
directors and to fill any vacancy caused by the resignation, death or removal of
such directors; (ii) the holders of Series B Preferred Stock, voting as a
separate class, shall be entitled to elect one (1) member of the Company's Board
of Directors at each meeting or pursuant to each consent of the Company's
stockholders for the election of directors, and to remove from office such
director and to fill any vacancy caused by the registration, death or removal of
such director; (iii) the holders of Common Stock, voting as a separate class,
shall be entitled to elect two (2) members of the Board of Directors at each
meeting or pursuant to each consent of the Company's stockholders for the
election of directors, and to remove from office such directors and to fill any
vacancy caused by the resignation, death or removal of such directors; and (iv)
the holders of Common Stock and Series Preferred, voting together as a single
class on an as-if-converted basis, shall be entitled to elect all remaining
members of the Board of Directors at each meeting or pursuant to each consent of
the Company's stockholders for the election of directors, and to remove from

                                      4.
<PAGE>

office such directors and to fill any vacancy caused by the resignation, death
or removal of such directors.

          3.   Liquidation Rights.

               (a)  Upon any liquidation, dissolution, or winding up of the
Company, whether voluntary or involuntary, before any distribution or payment
shall be made to the holders of any Junior Stock, the holders of Series
Preferred shall be entitled to be paid out of the assets of the Company an
amount per share of Series Preferred equal to the Original Issue Price plus all
declared and unpaid dividends on the Series Preferred (as adjusted for any stock
dividends, combinations, splits, recapitalizations and the like with respect to
such shares) for each share of Series Preferred held by them. If, upon any such
liquidation, distribution, or winding up, the assets of the Company shall be
insufficient to make payment in full to all holders of Series Preferred of the
liquidation preference set forth in this Section 3(a), then such assets shall be
distributed among the holders of Series Preferred at the time outstanding,
ratably in proportion to the full amounts to which they would otherwise be
respectively entitled.

               (b)  After the payment of the full liquidation preference of the
Series Preferred as set forth in Section 3(a) above, the assets of the Company
legally available for distribution, if any, shall be distributed ratably to the
holders of the Common Stock and Series Preferred on an as-if-converted to Common
Stock basis until such time as the holders of Series Preferred have received
pursuant to Section 3(a) above and this Section 3(b) in aggregate an amount per
share of Series Preferred equal to three (3) times the Original Issue Price (as
adjusted for any stock, dividends, combinations, splits, recapitalizations and
the like with respect to such shares); thereafter the remaining assets of the
Company legally available for distribution, if any, shall be distributed ratably
to the holders of the Common Stock.

               (c)  The following events shall be considered a liquidation under
this Section:

                    (i)    any consolidation or merger of the Company with or
into any other corporation or other entity or person, or any other corporate
reorganization, in which the stockholders of the Company immediately prior to
such consolidation, merger or reorganization, own less than 50% of the Company's
voting power immediately after such consolidation, merger or reorganization, or
any transaction or series of related transactions to which the Company is a
party in which in excess of fifty percent (50%) of the Company's voting power is
transferred, excluding any consolidation or merger effected exclusively to
change the domicile of the Company (an "Acquisition"); or

                    (ii)   a sale, lease or other disposition of all or
substantially all of the assets of the Company (an "Asset Transfer").

                    (iii)  In any of such events, if the consideration received
by this corporation is other than cash, its value will be deemed its fair market
value as determined in good faith by the Board of Directors. Any securities
shall be valued as follows:

                                      5.
<PAGE>

                           (A)   Securities not subject to investment letter or
other similar restrictions on free marketability covered by (B) below:

                                 (1)  If traded on a securities exchange or
through the Nasdaq National Market, the value shall be deemed to be the average
of the closing prices of the securities on such quotation system over the thirty
(30) day period ending three (3) days prior to the closing;

                                 (2)  If actively traded over-the-counter, the
value shall be deemed to be the average of the closing bid or sale prices
(whichever is applicable) over the thirty (30) day period ending three (3) days
prior to the closing; and

                                 (3)  If there is no active public market, the
value shall be the fair market value thereof, as determined by the Board of
Directors.

                           (B)   The method of valuation of securities subject
to investment letter or other restrictions on free marketability (other than
restrictions arising solely by virtue of a shareholder's status as an affiliate
or former affiliate) shall be to make an appropriate discount from the market
value determined as above in (A) (1), (2) or (3) to reflect the approximate fair
market value thereof, as determined by the Board of Directors.

          4.   Conversion Rights.

               The holders of the Series Preferred shall have the following
rights with respect to the conversion of the Series Preferred into shares of
Common Stock (the "Conversion Rights"):

               (a)  Optional Conversion.  Subject to and in compliance with the
provisions of this Section 4, any shares of Series Preferred may, at the option
of the holder, be converted at any time into fully-paid and nonassessable shares
of Common Stock. The number of shares of Common Stock to which a holder of
Series Preferred shall be entitled upon conversion shall be the product obtained
by multiplying the "Series Preferred Conversion Rate" then in effect (determined
as provided in Section 4(b)) by the number of shares of Series Preferred being
converted.

               (b)  Series Preferred Conversion Rate.  The conversion rate in
effect at any time for conversion of the Series Preferred (the "Series Preferred
Conversion Rate") shall be the quotient obtained by dividing the Original Issue
Price of the Series Preferred by the "Series Preferred Conversion Price,"
calculated as provided in Section 4(c).

               (c)  Series Preferred Conversion Price.  The conversion price for
the Series Preferred shall initially be the Original Issue Price of the Series
Preferred (the "Series Preferred Conversion Price"). Such initial Series
Preferred Conversion Price shall be adjusted from time to time in accordance
with this Section 4. All references to the Series Preferred Conversion Price
herein shall mean the Series Preferred Conversion Price as so adjusted.

                                      6.
<PAGE>

               (d)  Mechanics of Conversion.  Each holder of Series Preferred
who desires to convert the same into shares of Common Stock pursuant to this
Section 4 shall surrender the certificate or certificates therefor, duly
endorsed, at the office of the Company or any transfer agent for the Series
Preferred, and shall give written notice to the Company at such office that such
holder elects to convert the same. Such notice shall state the number of shares
of Series Preferred being converted. Thereupon, the Company shall promptly issue
and deliver at such office to such holder a certificate or certificates for the
number of shares of Common Stock to which such holder is entitled and shall
promptly pay (i) in cash or, to the extent sufficient funds are not then legally
available therefor, in Common Stock (at the Common Stock's fair market value
determined by the Board of Directors as of the date of such conversion), any
declared and unpaid dividends on the shares of Series Preferred being converted
and (ii) in cash (at the Common Stock's fair market value determined by the
Board of Directors as of the date of conversion) the value of any fractional
share of Common Stock otherwise issuable to any holder of Series Preferred. Such
conversion shall be deemed to have been made at the close of business on the
date of such surrender of the certificates representing the shares of Series
Preferred to be converted, and the person entitled to receive the shares of
Common Stock issuable upon such conversion shall be treated for all purposes as
the record holder of such shares of Common Stock on such date.

               (e)  Adjustment for Stock Splits and Combinations. If the Company
shall at any time or from time to time after the date that the first share of
Series Preferred is issued (the "Original Issue Date") effect a subdivision of
the outstanding Common Stock without a corresponding subdivision of the
Preferred Stock, the Series Preferred Conversion Price in effect immediately
before that subdivision shall be proportionately decreased. Conversely, if the
Company shall at any time or from time to time after the Original Issue Date
combine the outstanding shares of Common Stock into a smaller number of shares
without a corresponding combination of the Preferred Stock, the Series Preferred
Conversion Price in effect immediately before the combination shall be
proportionately increased. Any adjustment under this Section 4(e) shall become
effective at the close of business on the date the subdivision or combination
becomes effective.

               (f)  Adjustment for Common Stock Dividends and Distributions.  If
the Company at any time or from time to time after the Original Issue Date
makes, or fixes a record date for the determination of holders of Common Stock
entitled to receive, a dividend or other distribution payable in additional
shares of Common Stock, in each such event the Series Preferred Conversion Price
that is then in effect shall be decreased as of the time of such issuance or, in
the event such record date is fixed, as of the close of business on such record
date, by multiplying the Series Preferred Conversion Price then in effect by a
fraction (i) the numerator of which is the total number of shares of Common
Stock issued and outstanding immediately prior to the time of such issuance or
the close of business on such record date, and (ii) the denominator of which is
the total number of shares of Common Stock issued and outstanding immediately
prior to the time of such issuance or the close of business on such record date
plus the number of shares of Common Stock issuable in payment of such dividend
or distribution; provided, however, that if such record date is fixed and such
dividend is not fully paid or if such distribution is not fully made on the date
fixed therefor, the Series Preferred Conversion Price shall be recomputed
accordingly as of the close of business on such record date and thereafter the

                                      7.
<PAGE>

Series Preferred Conversion Price shall be adjusted pursuant to this Section
4(f) to reflect the actual payment of such dividend or distribution.

               (g)  Adjustment for Reclassification, Exchange and Substitution.
If at any time or from time to time after the Original Issue Date, the Common
Stock issuable upon the conversion of the Series Preferred is changed into the
same or a different number of shares of any class or classes of stock, whether
by recapitalization, reclassification or otherwise (other than an Acquisition or
Asset Transfer as defined in Section 3(c) or a subdivision or combination of
shares or stock dividend or a reorganization, merger, consolidation or sale of
assets provided for elsewhere in this Section 4), in any such event each holder
of Series Preferred shall have the right thereafter to convert such stock into
the kind and amount of stock and other securities and property receivable upon
such recapitalization, reclassification or other change by holders of the
maximum number of shares of Common Stock into which such shares of Series
Preferred could have been converted immediately prior to such recapitalization,
reclassification or change, all subject to further adjustment as provided herein
or with respect to such other securities or property by the terms thereof.

               (h)  Reorganizations, Mergers, Consolidations or Sales of Assets.
If at any time or from time to time after the Original Issue Date, there is a
capital reorganization of the Common Stock (other than an Acquisition or Asset
Transfer as defined in Section 3(c) or a recapitalization, subdivision,
combination, reclassification, exchange or substitution of shares provided for
elsewhere in this Section 4), as a part of such capital reorganization,
provision shall be made so that the holders of the Series Preferred shall
thereafter be entitled to receive upon conversion of the Series Preferred the
number of shares of stock or other securities or property of the Company to
which a holder of the number of shares of Common Stock deliverable upon
conversion would have been entitled on such capital reorganization, subject to
adjustment in respect of such stock or securities by the terms thereof. In any
such case, appropriate adjustment shall be made in the application of the
provisions of this Section 4 with respect to the rights of the holders of Series
Preferred after the capital reorganization to the end that the provisions of
this Section 4 (including adjustment of the Series Preferred Conversion Price
then in effect and the number of shares issuable upon conversion of the Series
Preferred) shall be applicable after that event and be as nearly equivalent as
practicable.

               (i)  Sale of Shares Below Series Preferred Conversion Price.

                    (i)    If at any time or from time to time after the
Original Issue Date, the Company issues or sells, or is deemed by the express
provisions of this subsection (i) to have issued or sold, Additional Shares of
Common Stock (as defined in subsection (i)(iv) below), other than as a dividend
or other distribution on any class of stock as provided in Section 4(f) above,
and other than a subdivision or combination of shares of Common Stock as
provided in Section 4(e) above, for an Effective Price (as defined in subsection
(i)(iv) below) less than the then effective Series Preferred Conversion Price,
then and in each such case the then existing Series Preferred Conversion Price
shall be reduced, as of the opening of business on the date of such issue or
sale, to a price determined by multiplying the Series Preferred Conversion Price
by a fraction (i) the numerator of which shall be (A) the number of shares of
Common Stock deemed outstanding (as defined below) immediately prior to such
issue or sale, plus (B) the

                                      8.
<PAGE>

number of shares of Common Stock which the aggregate consideration received (as
defined in subsection (i)(ii) by the Company for the total number of Additional
Shares of Common Stock so issued would purchase at such Series Preferred
Conversion Price, and (ii) the denominator of which shall be the number of
shares of Common Stock deemed outstanding (as defined below) immediately prior
to such issue or sale plus the total number of Additional Shares of Common Stock
so issued. For the purposes of the preceding sentence, the number of shares of
Common Stock deemed to be outstanding as of a given date shall be the sum of (A)
the number of shares of Common Stock actually outstanding, (B) the number of
shares of Common Stock into which the then outstanding shares of Series
Preferred could be converted if fully converted on the day immediately preceding
the given date, and (C) the number of shares of Common Stock which could be
obtained through the exercise or conversion of all other rights, options and
convertible securities outstanding on the day immediately preceding the given
date.

                    (ii)   For the purpose of making any adjustment required
under this Section 4(i), the consideration received by the Company for any issue
or sale of securities shall (A) to the extent it consists of cash, be computed
at the net amount of cash received by the Company after deduction of any
underwriting or similar commissions, compensation or concessions paid or allowed
by the Company in connection with such issue or sale but without deduction of
any expenses payable by the Company, (B) to the extent it consists of property
other than cash, be computed at the fair value of that property as determined in
good faith by the Board of Directors, and (C) if Additional Shares of Common
Stock, Convertible Securities (as defined in subsection (i)(iii)) or rights or
options to purchase either Additional Shares of Common Stock or Convertible
Securities are issued or sold together with other stock or securities or other
assets of the Company for a consideration which covers both, be computed as the
portion of the consideration so received that may be reasonably determined in
good faith by the Board of Directors to be allocable to such Additional Shares
of Common Stock, Convertible Securities or rights or options.

                    (iii)  For the purpose of the adjustment required under this
Section 4(i), if the Company issues or sells (i) stock or other securities
convertible into, Additional Shares of Common Stock (such convertible stock or
securities being herein referred to as "Convertible Securities") or (ii) rights
or options for the purchase of Additional Shares of Common Stock or Convertible
Securities and if the Effective Price of such Additional Shares of Common Stock
is less than the Series Preferred Conversion Price, in each case the Company
shall be deemed to have issued at the time of the issuance of such rights or
options or Convertible Securities the maximum number of Additional Shares of
Common Stock issuable upon exercise or conversion thereof and to have received
as consideration for the issuance of such shares an amount equal to the total
amount of the consideration, if any, received by the Company for the issuance of
such rights or options or Convertible Securities, plus, in the case of such
rights or options, the minimum amounts of consideration, if any, payable to the
Company upon the exercise of such rights or options, plus, in the case of
Convertible Securities, the minimum amounts of consideration, if any, payable to
the Company (other than by cancellation of liabilities or obligations evidenced
by such Convertible Securities) upon the conversion thereof; provided that if in
the case of Convertible Securities the minimum amounts of such consideration
cannot be ascertained, but are a function of antidilution or similar protective
clauses, the Company shall be deemed to have received the minimum amounts of
consideration without reference to such

                                      9.
<PAGE>

clauses; provided further that if the minimum amount of consideration payable to
the Company upon the exercise or conversion of rights, options or Convertible
Securities is reduced over time or on the occurrence or non-occurrence of
specified events other than by reason of antidilution adjustments, the Effective
Price shall be recalculated using the figure to which such minimum amount of
consideration is reduced; provided further that if the minimum amount of
consideration payable to the Company upon the exercise or conversion of such
rights, options or Convertible Securities is subsequently increased, the
Effective Price shall be again recalculated using the increased minimum amount
of consideration payable to the Company upon the exercise or conversion of such
rights, options or Convertible Securities. No further adjustment of the Series
Preferred Conversion Price, as adjusted upon the issuance of such rights,
options or Convertible Securities, shall be made as a result of the actual
issuance of Additional Shares of Common Stock on the exercise of any such rights
or options or the conversion of any such Convertible Securities. If any such
rights or options or the conversion privilege represented by any such
Convertible Securities shall expire without having been exercised, the Series
Preferred Conversion Price as adjusted upon the issuance of such rights, options
or Convertible Securities shall be readjusted to the Series Preferred Conversion
Price which would have been in effect had an adjustment been made on the basis
that the only Additional Shares of Common Stock so issued were the Additional
Shares of Common Stock, if any, actually issued or sold on the exercise of such
rights or options or rights of conversion of such Convertible Securities, and
such Additional Shares of Common Stock, if any, were issued or sold for the
consideration actually received by the Company upon such exercise, plus the
consideration, if any, actually received by the Company for the granting of all
such rights or options, whether or not exercised, plus the consideration
received for issuing or selling the Convertible Securities actually converted,
plus the consideration, if any, actually received by the Company (other than by
cancellation of liabilities or obligations evidenced by such Convertible
Securities) on the conversion of such Convertible Securities, provided that such
readjustment shall not apply to prior conversions of Series Preferred.

                    (IV)   "Additional Shares of Common Stock" shall mean all
shares of Common Stock issued by the Company or deemed to be issued pursuant to
this Section 4(i), other than (A) shares of Common Stock issued upon conversion
of the Series Preferred; (B) shares of Common Stock and/or options, warrants or
other Common Stock purchase rights, and the Common Stock issued pursuant to such
options, warrants or other rights (as adjusted for any stock dividends,
combinations, splits, recapitalizations and the like) after the Original Issue
Date to employees, officers or directors of, or consultants or advisors to the
Company or any subsidiary pursuant to stock purchase or stock option plans or
other arrangements that are approved by the Board; (C) shares of Common Stock
issued pursuant to the exercise of options, warrants or convertible securities
outstanding as of the Original Issue Date, (D) shares of Common Stock and/or
options, warrants or other Common Stock purchase rights, and the Common Stock
issued pursuant to such options, warrants or other rights issued for
consideration other than cash pursuant to a merger, consolidation, acquisition
or similar business combination approved by the Board and (E) shares of Common
Stock issued pursuant to any equipment leasing arrangement, or debt financing
from a bank or similar financial institution approved by the Board. References
to Common Stock in the subsections of this clause (iv) above shall mean all
shares of Common Stock issued by the Company or deemed to be issued pursuant

                                      10.
<PAGE>

to this Section 4(i). The "Effective Price" of Additional Shares of Common Stock
shall mean the quotient determined by dividing the total number of Additional
Shares of Common Stock issued or sold, or deemed to have been issued or sold by
the Company under this Section 4(i), into the aggregate consideration received,
or deemed to have been received by the Company for such issue under this Section
4(i), for such Additional Shares of Common Stock.

               (j)  Certificate of Adjustment.  In each case of an adjustment or
readjustment of the Series Preferred Conversion Price for the number of shares
of Common Stock or other securities issuable upon conversion of the Series
Preferred, if the Series Preferred is then convertible pursuant to this Section
4, the Company, at its expense, shall compute such adjustment or readjustment in
accordance with the provisions hereof and prepare a certificate showing such
adjustment or readjustment, and shall mail such certificate, by first class
mail, postage prepaid, to each registered holder of Series Preferred at the
holder's address as shown in the Company's books. The certificate shall set
forth such adjustment or readjustment, showing in detail the facts upon which
such adjustment or readjustment is based, including a statement of (i) the
consideration received or deemed to be received by the Company for any
Additional Shares of Common Stock issued or sold or deemed to have been issued
or sold, (ii) the Series Preferred Conversion Price at the time in effect, (iii)
the number of Additional Shares of Common Stock and (iv) the type and amount, if
any, of other property which at the time would be received upon conversion of
the Series Preferred.

               (k)  Notices of Record Date.  Upon (i) any taking by the Company
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 or
other distribution, or (ii) any Acquisition (as defined in Section 3(c)) or
other capital reorganization of the Company, any reclassification or
recapitalization of the capital stock of the Company, any merger or
consolidation of the Company with or into any other corporation, or any Asset
Transfer (as defined in Section 3(c)), or any voluntary or involuntary
dissolution, liquidation or winding up of the Company, the Company shall mail to
each holder of Series Preferred at least ten (10) days prior to the record date
specified therein (or such shorter period approved by a majority of the
outstanding Series Preferred) a notice specifying (A) the date on which any such
record is to be taken for the purpose of such dividend or distribution and a
description of such dividend or distribution, (B) the date on which any such
Acquisition, reorganization, reclassification, transfer, consolidation, merger,
Asset Transfer, dissolution, liquidation or winding up is expected to become
effective, and (C) the date, if any, that is to be fixed as to when the holders
of record of Common Stock (or other securities) shall be entitled to exchange
their shares of Common Stock (or other securities) for securities or other
property deliverable upon such Acquisition, reorganization, reclassification,
transfer, consolidation, merger, Asset Transfer, dissolution, liquidation or
winding up.

               (l)  Automatic Conversion.

                    (i)   Each share of Series Preferred shall automatically be
converted into shares of Common Stock, based on the then-effective Series
Preferred Conversion Price, (A) at any time upon the affirmative election of the
holders of at least a majority of the

                                      11.
<PAGE>

outstanding shares of the Series A Preferred Stock and of the holders of at
least a majority of the outstanding shares of the Series B Preferred Stock, or
(B) immediately upon the closing of a firmly underwritten public offering
pursuant to an effective registration statement under the Securities Act of
1933, as amended, covering the offer and sale of Common Stock for the account of
the Company in which (i) the per share price is at least $9.375 (as adjusted for
stock splits, dividends, recapitalizations and the like), and (ii) the gross
cash proceeds to the Company (before underwriting discounts, commissions and
fees) are at least $10,000,000. Upon such automatic conversion, any declared and
unpaid dividends shall be paid in accordance with the provisions of Section
4(d).

                    (ii)  Upon the occurrence of either of the events specified
in Section 4(l)(i) above, the outstanding shares of Series Preferred shall be
converted automatically without any further action by the holders of such shares
and whether or not the certificates representing such shares are surrendered to
the Company or its transfer agent; provided, however, that the Company shall not
be obligated to issue certificates evidencing the shares of Common Stock
issuable upon such conversion unless the certificates evidencing such shares of
Series Preferred are either delivered to the Company or its transfer agent as
provided below, or the holder notifies the Company or its transfer agent that
such certificates have been lost, stolen or destroyed and executes an agreement
satisfactory to the Company to indemnify the Company from any loss incurred by
it in connection with such certificates. Upon the occurrence of such automatic
conversion of the Series Preferred, the holders of Series Preferred shall
surrender the certificates representing such shares at the office of the Company
or any transfer agent for the Series Preferred. Thereupon, there shall be issued
and delivered to such holder promptly at such office and in its name as shown on
such surrendered certificate or certificates, a certificate or certificates for
the number of shares of Common Stock into which the shares of Series Preferred
surrendered were convertible on the date on which such automatic conversion
occurred, and any declared and unpaid dividends shall be paid in accordance with
the provisions of Section 4(d).

               (m)  Fractional Shares.  No fractional shares of Common Stock
shall be issued upon conversion of Series Preferred. All shares of Common Stock
(including fractions thereof) issuable upon conversion of more than one share of
Series Preferred by a holder thereof shall be aggregated for purposes of
determining whether the conversion would result in the issuance of any
fractional share. If, after the aforementioned aggregation, the conversion would
result in the issuance of any fractional share, the Company shall, in lieu of
issuing any fractional share, pay cash equal to the product of such fraction
multiplied by the Common Stock's fair market value (as determined by the Board
of Directors) on the date of conversion.

               (n)  Reservation of Stock Issuable Upon Conversion.  The Company
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 Preferred, 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 Preferred. 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 Preferred, the
Company will take such corporate action as may, in the opinion of its counsel,
be necessary to increase its authorized but unissued shares of Common Stock to
such number of shares as shall be sufficient for such purpose.

holders of then outstanding Series Preferred as required under Section 2(b), the
Company shall not amend its Restated Certificate of Incorporation or participate
in any reorganization, transfer of assets, consolidation, merger, dissolution,
issue or sale of securities or take any other voluntary action, for the purpose
of avoiding or seeking to avoid the observance or performance of any of the
terms to be observed or performed hereunder by the Company, but shall at all
times in good faith assist in carrying out all such action as may be reasonably
necessary or appropriate in order to protect the conversion rights of the
holders of the Series Preferred against dilution or other impairment.

          5.   No Reissuance of Series Preferred.

               No share or shares of Series Preferred acquired by the

     A.   The liability of the directors for monetary damages shall be
eliminated to the fullest extent under applicable law.

     B.   Any repeal or modification of this Article V shall only be prospective
and shall not effect the rights under this Article V in effect at the time of
the alleged occurrence of any action or omission to act giving rise to
liability.

                                      VI.

     For the management of the business and for the conduct of the affairs of
the Corporation, and in further definition, limitation and regulation of the

by the Board of Directors by the affirmative vote of the percentage of holders
of capital stock as provided therein; and, provided further, that no amendment
or supplement to the Bylaws adopted by the Board of Directors shall vary or
conflict with any amendment or supplement thus adopted by the stockholders.

SECTION 2.  REGISTRATION; RESTRICTIONS ON TRANSFER

     2.1  Restrictions on Transfer.

          (a)  Each Holder agrees not to make any disposition of all or any
portion of the Shares or Registrable Securities unless and until:

               (i)   There is then in effect a registration statement under the
Securities Act covering such proposed disposition and such disposition is made
in accordance with such registration statement; or

               (ii)  (A) The transferee has agreed in writing to be bound by the
terms of this Agreement, (B) such Holder shall have notified the Company of the
proposed disposition and shall have furnished the Company with a detailed
statement of the circumstances surrounding the proposed disposition, and (C) if
reasonably requested by the Company, such Holder shall have furnished the
Company with an opinion of counsel, reasonably satisfactory to the Company, that
such disposition will not require registration of such shares under the
Securities Act. It is agreed that the Company will not require opinions of
counsel for transactions made pursuant to Rule 144 except in unusual
circumstances.

               (iii) Notwithstanding the provisions of paragraphs (i) and (ii)
above, no such registration statement or opinion of counsel shall be necessary
for a transfer by a Holder which is (A) a partnership to its partners or former
partners in accordance with partnership interests, (B) a corporation to its
shareholders in accordance with their interest in the corporation, (C) a limited
liability company to its members or former members in accordance with their
interest in the limited liability company, or (D) to the Holder's family member
or trust for the benefit of an individual Holder; provided that in each case the
transferee will be subject to the terms of this Agreement to the same extent as
if he were an original Holder hereunder.

          (b)  Each certificate representing Shares or Registrable Securities
shall (unless otherwise permitted by the provisions of the Agreement) be stamped
or otherwise imprinted with a legend substantially similar to the following (in
addition to any legend required under applicable state securities laws):

          THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
          UNDER THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE
          OFFERED, SOLD OR OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED OR
          HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR
          UNLESS THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL
          SATISFACTORY TO THE COMPANY AND ITS COUNSEL THAT SUCH
          REGISTRATION IS NOT REQUIRED.

          (c)  The Company shall be obligated to reissue promptly unlegended
certificates at the request of any holder thereof if the holder shall have
obtained an opinion of counsel (which counsel may be counsel to the Company)
reasonably acceptable to the Company to the effect that the securities proposed
to be disposed of may lawfully be so disposed of without registration,
qualification or legend.

                                      3.
<PAGE>

          (d)  Any legend endorsed on an instrument pursuant to applicable state
securities laws and the stop-transfer instructions with respect to such
securities shall be removed upon receipt by the Company of an order of the
appropriate blue sky authority authorizing such removal.

     2.2  Demand Registration.

          (a)  Subject to the conditions of this Section 2.2, if the Company
shall receive a written request from the Holders (the "Initiating Holders")
proposing to sell Registrable Securities at an anticipated aggregate offering
price, net of underwriting discounts and commissions, exceeding ten million
dollars ($10,000,000) (a "Qualified Public Offering")), then the Company shall,
within thirty (30) days of the receipt thereof, give written notice of such
request to all Holders, and subject to the limitations of this Section 2.2, use
its best efforts to effect, as soon as practicable, the registration under the
Securities Act of all Registrable Securities that the Holders request to be
registered.

          (b)  If the Initiating Holders intend to distribute the Registrable
Securities covered by their request by means of an underwriting, they shall so
advise the Company as a part of their request made pursuant to this Section 2.2
or any request pursuant to Section 2.4 and the Company shall include such
information in the written notice referred to in Section 2.2(a) or Section
2.4(a), as applicable.  In such event, the right of any Holder to include its
Registrable Securities in such registration shall be conditioned upon such
Holder's participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting to the extent provided herein.  All
Holders proposing to distribute their securities through such underwriting shall
enter into an underwriting agreement in customary form with the underwriter or
underwriters selected for such underwriting by a majority in interest of the
Initiating Holders (which underwriter or underwriters shall be reasonably
acceptable to the Company).  Notwithstanding any other provision of this Section
2.2 or Section 2.4, if the underwriter advises the Company that marketing
factors require a limitation of the number of securities to be underwritten
(including Registrable Securities) then the Company shall so advise all Holders
of Registrable Securities which would otherwise be underwritten pursuant hereto,
and the number of shares that may be included in the underwriting shall be
allocated to the Holders of such Registrable Securities on a pro rata basis
based on the number of Registrable Securities held by all such Holders
(including the Initiating Holders); provided, however, that the number of shares
of Registrable Securities to be included in such underwriting and registration
shall not be reduced unless all other securities of the Company are first
entirely excluded from the underwriting and registration.  Any Registrable
Securities excluded or withdrawn from such underwriting shall be withdrawn from
the registration.

          (c)  The Company shall not be required to effect a registration
pursuant to this Section 2.2:

               (i)  prior to one hundred eighty (180) days following the
effective date of the registration statement pertaining to the Initial Offering;

               (ii) after the Company has effected two (2) registrations
pursuant to this Section 2.2, and such registrations have been declared or
ordered effective;

                                      4.
<PAGE>

               (iii) if the Company shall furnish to Holders requesting a
registration statement pursuant to this Section 2.2, a certificate signed by the
Chairman of the Board stating that in the good faith judgment of the Board of
Directors of the Company, it would be seriously detrimental to the Company and
its shareholders for such registration statement to be effected at such time, in
which event the Company shall have the right to defer such filing for a period
of not more than ninety (90) days after receipt of the request of the Initiating
Holders; provided that such right to delay a request shall be exercised by the
Company not more than once in any twelve (12) month period; or

               (iv)  if the Initiating Holders propose to dispose of shares of
Registrable Securities that may be immediately registered on Form S-3 pursuant
to a request made pursuant to Section 2.4 below.

     2.3  Piggyback Registrations.  The Company shall notify all Holders of
Registrable Securities in writing at least fifteen (15) days prior to the filing
of any registration statement under the Securities Act for purposes of a public
offering of securities of the Company (including, but not limited to,
registration statements relating to secondary offerings of securities of the
Company, but excluding registration statements relating to employee benefit
plans or with respect to corporate reorganizations or other transactions under
Rule 145 of the Securities Act) and will afford each such Holder an opportunity
to include in such registration statement all or part of such Registrable
Securities held by such Holder.  Each Holder desiring to include in any such
registration statement all or any part of the Registrable Securities held by it
shall, within ten (10) days after the above-described notice from the Company,
so notify the Company in writing.  Such notice shall state the intended method
of disposition of the Registrable Securities by such Holder.  If a Holder
decides not to include all of its Registrable Securities in any registration
statement thereafter filed by the Company, such Holder shall nevertheless
continue to have the right to include any Registrable Securities in any
subsequent registration statement or registration statements as may be filed by
the Company with respect to offerings of its securities, all upon the terms and
conditions set forth herein.

          (a)  Underwriting.  If the registration statement under which the
Company gives notice under this Section 2.3 is for an underwritten offering, the
Company shall so advise the Holders of Registrable Securities. In such event,
the right of any such Holder to be included in a registration pursuant to this
Section 2.3 shall be conditioned upon such Holder's participation in such
underwriting and the inclusion of such Holder's Registrable Securities in the
underwriting to the extent provided herein. All Holders proposing to distribute
their Registrable Securities through such underwriting shall enter into an
underwriting agreement in customary form with the underwriter or underwriters
selected for such underwriting by the Company. Notwithstanding any other
provision of the Agreement, if the underwriter determines in good faith that
marketing factors require a limitation of the number of shares to be
underwritten, the number of shares that may be included in the underwriting
shall be allocated, first, to the Company; second, to the Holders on a pro rata
basis based on the total number of Registrable Securities held by the Holders;
and third, to any shareholder of the Company (other than a Holder) on a pro rata
basis. No such reduction shall (i) reduce the securities being offered by the
Company for its own account to be included in the registration and underwriting,
or (ii) reduce the amount of securities of the selling Holders included in the
registration below twenty-five percent (25%) of the total amount of securities
included in such registration, unless

                                      5.
<PAGE>

such offering is the Initial Offering and such registration does not include
shares of any other selling shareholders, in which event any or all of the
Registrable Securities of the Holders may be excluded in accordance with the
immediately preceding sentence. In no event will shares of any other selling
shareholder be included in such registration which would reduce the number of
shares which may be included by Holders without the written consent of Holders
of not less than a majority of the Registrable Securities proposed to be sold in
the offering. If any Holder disapproves of the terms of any such underwriting,
such Holder may elect to withdraw therefrom by written notice to the Company and
the underwriter, delivered at least ten (10) business days prior to the
effective date of the registration statement. Any Registrable Securities
excluded or withdrawn from such underwriting shall be excluded and withdrawn
from the registration. For any Holder which is a partnership or corporation, the
partners, retired partners and shareholders of such Holder, or the estates and
family members of any such partners and retired partners and any trusts for the
benefit of any of the foregoing person shall be deemed to be a single "Holder",
and any pro rata reduction with respect to such "Holder" shall be based upon the
aggregate amount of shares carrying registration rights owned by all entities
and individuals included in such "Holder," as defined in this sentence.

          (b)  Right to Terminate Registration.  The Company shall have the
right to terminate or withdraw any registration initiated by it under this
Section 2.3 prior to the effectiveness of such registration whether or not any
Holder has elected to include securities in such registration. The Registration
Expenses of such withdrawn registration shall be borne by the Company in
accordance with Section 2.5 hereof.

     2.4  Form S-3 Registration.  In case the Company shall receive from any
Holder or Holders of Registrable Securities a written request or requests that
the Company effect a registration on Form S-3 (or any successor to Form S-3) or
any similar short-form registration statement and any related qualification or
compliance with respect to all or a part of the Registrable Securities owned by
such Holder or Holders, the Company will:

          (a)  promptly give written notice of the proposed registration, and
any related qualification or compliance, to all other Holders of Registrable
Securities; and

          (b)  as soon as practicable, effect such registration and all such
qualifications and compliances as may be so requested and as would permit or
facilitate the sale and distribution of all or such portion of such Holder's or
Holders' Registrable Securities as are specified in such request, together with
all or such portion of the Registrable Securities of any other Holder or Holders
joining in such request as are specified in a written request given within
fifteen (15) days after receipt of such written notice from the Company;
provided, however, that the Company shall not be obligated to effect any such
registration, qualification or compliance pursuant to this Section 2.4:

               (i)  if Form S-3 (or any successor or similar form) is not
available for such offering by the Holders, or

               (ii) if the Holders, together with the holders of any other
securities of the Company entitled to inclusion in such registration, propose to
sell Registrable Securities and

                                      6.
<PAGE>

such other securities (if any) at an aggregate price to the public of less than
two million dollars ($2,000,000), or

               (iii) if within thirty (30) days of receipt of a written request
from any Holder or Holders pursuant to this Section 2.4, the Company gives
notice to such Holder or Holders of the Company's intention to make a public
offering within ninety (90) days;

               (iv)  if the Company shall furnish to the Holders a certificate
signed by the Chairman of the Board of Directors of the Company stating that in
the good faith judgment of the Board of Directors of the Company, it would be
seriously detrimental to the Company and its shareholders for such Form S-3
registration to be effected at such time, in which event the Company shall have
the right to defer the filing of the Form S-3 registration statement for a
period of not more than ninety (90) days after receipt of the request of the
Holder or Holders under this Section 2.4; provided, that such right to delay a
request shall be exercised by the Company not more than once in any twelve (12)
month period, or

               (v)   in any particular jurisdiction in which the Company would
be required to qualify to do business or to execute a general consent to service
of process in effecting such registration, qualification or compliance.

          (c)  Subject to the foregoing, the Company shall file a Form S-3
registration statement covering the Registrable Securities and other securities
so requested to be registered as soon as practicable after receipt of the
request or requests of the Holders.  Registrations effected pursuant to this
Section 2.4 shall not be counted as demands for registration or registrations
effected pursuant to Sections 2.2 or 2.3, respectively.

     2.5  Expenses of Registration.  Except as specifically provided herein, all
Registration Expenses incurred in connection with any registration,
qualification or compliance pursuant to Section 2.2 or any registration under
Section 2.3 or Section 2.4 herein shall be borne by the Company. All Selling
Expenses incurred in connection with any registrations hereunder, shall be borne
by the holders of the securities so registered pro rata on the basis of the
number of shares so registered. The Company shall not, however, be required to
pay for expenses of any registration proceeding begun pursuant to Section 2.2 or
2.4, the request of which has been subsequently withdrawn by the Initiating
Holders unless (a) the withdrawal is based upon material adverse information
concerning the Company of which the Initiating Holders were not aware at the
time of such request or (b) the Holders of a majority of Registrable Securities
agree to forfeit their right to one requested registration pursuant to Section
2.2 or Section 2.4, as applicable, in which event such right shall be forfeited
by all Holders. If the Holders are required to pay the Registration Expenses,
such expenses shall be borne by the holders of securities (including Registrable
Securities) requesting such registration in proportion to the number of shares
for which registration was requested. If the Company is required to pay the
Registration Expenses of a withdrawn offering pursuant to clause (a) above, then
the Holders shall not forfeit their rights pursuant to Section 2.2 or Section
2.4 to a demand registration.

                                      7.
<PAGE>

     2.6  Obligations of the Company.  Whenever required to effect the
registration of any Registrable Securities, the Company shall, as expeditiously
as reasonably possible:

          (a)  Prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use all reasonable efforts to cause
such registration statement to become effective, and, upon the request of the
Holders of a majority of the Registrable Securities registered thereunder, keep
such registration statement effective for up to thirty (30) days or, if earlier,
until the Holder or Holders have completed the distribution related thereto. The
Company shall not be required to file, cause to become effective or maintain the
effectiveness of any registration statement that contemplates a distribution of
securities on a delayed or continuous basis pursuant to Rule 415 under the
Securities Act.

          (b)  Prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Securities Act with respect to the disposition of all securities covered by such
registration statement for the period set forth in paragraph (a) above.

          (c)  Furnish to the Holders such number of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Securities Act, and such other documents as they may reasonably request in order
to facilitate the disposition of Registrable Securities owned by them.

          (d)  Use its reasonable best efforts to register and qualify the
securities covered by such registration statement under such other securities or
Blue Sky laws of such jurisdictions as shall be reasonably requested by the
Holders; provided that the Company shall not be required in connection therewith
or as a condition thereto to qualify to do business or to file a general consent
to service of process in any such states or jurisdictions.

          (e)  In the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter(s) of such offering.  Each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement.

          (f)  Notify each Holder of Registrable Securities covered by such
registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing.

          (g)  Use its best efforts to furnish, on the date that such
Registrable Securities are delivered to the underwriters for sale, if such
securities are being sold through underwriters, (i) an opinion, dated as of such
date, of the counsel representing the Company for the purposes of such
registration, in form and substance as is customarily given to underwriters in
an underwritten public offering, addressed to the underwriters, if any, and (ii)
a letter dated as of such date, from the independent certified public
accountants of the Company, in form and

                                      8.
<PAGE>

substance as is customarily given by independent certified public accountants to
underwriters in an underwritten public offering addressed to the underwriters.

     2.7  Termination of Registration Rights.  All registration rights granted
under this Section 2 shall terminate and be of no further force and effect three
(3) years after the date of the Company's Initial Offering.  In addition, a
Holder's registration rights shall expire if all Registrable Securities held by
and issuable to such Holder (and its affiliates, partners, former partners,
members and former members) may be sold under Rule 144 during any ninety (90)
day period.

     2.8  Delay of Registration; Furnishing Information.

          (a)  No Holder shall have any right to obtain or seek an injunction
restraining or otherwise delaying any such registration as the result of any
controversy that might arise with respect to the interpretation or
implementation of this Section 2.

          (b)  It shall be a condition precedent to the obligations of the
Company to take any action pursuant to Section 2.2, 2.3 or 2.4 that the selling
Holders shall furnish to the Company such information regarding themselves, the
Registrable Securities held by them and the intended method of disposition of
such securities as shall be required to effect the registration of their
Registrable Securities.

          (c)  The Company shall have no obligation with respect to any
registration requested pursuant to Section 2.2 or Section 2.4 if, due to the
operation of subsection 2.2(b), the number of shares or the anticipated
aggregate offering price of the Registrable Securities to be included in the
registration does not equal or exceed the number of shares or the anticipated
aggregate offering price required to originally trigger the Company's obligation
to initiate such registration as specified in Section 2.2 or Section 2.4,
whichever is applicable.

     2.9  Indemnification.  In the event any Registrable Securities are included
in a registration statement under Sections 2.2, 2.3 or 2.4:

          (a)  To the extent permitted by law, the Company will indemnify and
hold harmless each Holder, the partners, officers and directors of each Holder,
any underwriter (as defined in the Securities Act) for such Holder and each
person, if any, who controls such Holder or underwriter within the meaning of
the Securities Act or the Exchange Act, against any losses, claims, damages, or
liabilities (joint or several) to which they may become subject under the
Securities Act, the Exchange Act or other federal or state law, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any of the following statements, omissions or violations
(collectively a "Violation") by the Company: (i) any untrue statement or alleged
untrue statement of a material fact contained in such registration statement,
including any preliminary prospectus or final prospectus contained therein or
any amendments or supplements thereto, (ii) the omission or alleged omission to
state therein a material fact required to be stated therein, or necessary to
make the statements therein not misleading, or (iii) any violation or alleged
violation by the Company of the Securities Act, the Exchange Act, any state
securities law or any rule or regulation promulgated under the Securities Act,
the Exchange Act or any state securities law in connection with the offering
covered by

                                      9.
<PAGE>

such registration statement; and the Company will pay as incurred to each such
Holder, partner, officer, director, underwriter or controlling person for any
legal or other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action;
provided however, that the indemnity agreement contained in this Section 2.9(a)
shall not apply to amounts paid in settlement of any such loss, claim, damage,
liability or action if such settlement is effected without the consent of the
Company, which consent shall not be unreasonably withheld, nor shall the Company
be liable in any such case for any such loss, claim, damage, liability or action
to the extent that it arises out of or is based upon a Violation which occurs in
reliance upon and in conformity with written information furnished expressly for
use in connection with such registration by such Holder, partner, officer,
director, underwriter or controlling person of such Holder.

          (b)  To the extent permitted by law, each Holder will, if Registrable
Securities held by such Holder are included in the securities as to which such
registration qualifications or compliance is being effected, indemnify and hold
harmless the Company, each of its directors, its officers and each person, if
any, who controls the Company within the meaning of the Securities Act, any
underwriter and any other Holder selling securities under such registration
statement or any of such other Holder's partners, directors or officers or any
person who controls such Holder, against any losses, claims, damages or
liabilities (joint or several) to which the Company or any such director,
officer, controlling person, underwriter or other such Holder, or partner,
director, officer or controlling person of such other Holder may become subject
under the Securities Act, the Exchange Act or other federal or state law,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereto) arise out of or are based upon any Violation, in each case to the
extent (and only to the extent) that such Violation occurs in reliance upon and
in conformity with written information furnished by such Holder under an
instrument duly executed by such Holder and stated to be specifically for use in
connection with such registration; and each such Holder will pay as incurred any
legal or other expenses reasonably incurred by the Company or any such director,
officer, controlling person, underwriter or other Holder, or partner, officer,
director or controlling person of such other Holder in connection with
investigating or defending any such loss, claim, damage, liability or action if
it is judicially determined that there was such a Violation; provided, however,
that the indemnity agreement contained in this Section 2.9(b) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action
if such settlement is effected without the consent of the Holder, which consent
shall not be unreasonably withheld; provided further, that in no event shall any
indemnity under this Section 2.9 exceed the proceeds from the offering received
by such Holder.

          (c)  Promptly after receipt by an indemnified party under this Section
2.9 of notice of the commencement of any action (including any governmental
action), such indemnified party will, if a claim in respect thereof is to be
made against any indemnifying party under this Section 2.9, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the fees and expenses to be paid
by the indemnifying party, if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to actual
or potential differing interests between such indemnified party and any other
party represented by such

                                      10.
<PAGE>

counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action, if materially prejudicial to its ability to defend such action, shall
relieve such indemnifying party of any liability to the indemnified party under
this Section 2.9, but the omission so to deliver written notice to the
indemnifying party will not relieve it of any liability that it may have to any
indemnified party otherwise than under this Section 2.9.

          (d)  If the indemnification provided for in this Section 2.9 is held
by a court of competent jurisdiction to be unavailable to an indemnified party
with respect to any losses, claims, damages or liabilities referred to herein,
the indemnifying party, in lieu of indemnifying such indemnified party
thereunder, shall to the extent permitted by applicable law contribute to the
amount paid or payable by such indemnified party as a result of such loss,
claim, damage or liability in such proportion as is appropriate to reflect the
relative fault of the indemnifying party on the one hand and of the indemnified
party on the other in connection with the Violation(s) that resulted in such
loss, claim, damage or liability, as well as any other relevant equitable
considerations. The relative fault of the indemnifying party and of the
indemnified party shall be determined by a court of law by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission; provided, that in no event shall any contribution by a
Holder hereunder exceed the proceeds from the offering received by such Holder.

          (e)  The obligations of the Company and Holders under this Section 2.9
shall survive completion of any offering of Registrable Securities in a
registration statement and the termination of this agreement. No Indemnifying
Party, in the defense of any such claim or litigation, shall, except with the
consent of each Indemnified Party, consent to entry of any judgment or enter
into any settlement which does not include as an unconditional term thereof the
giving by the claimant or plaintiff to such Indemnified Party of a release from
all liability in respect to such claim or litigation.

     2.10 Assignment of Registration Rights.  The rights to cause the Company to
register Registrable Securities pursuant to this Section 2 may be assigned by a
Holder to a transferee or assignee of Registrable Securities which (a) is an
Affiliate, general partner, limited partner, retired partner, member or retired
member of a Holder, (b) is a Holder's family member or trust for the benefit of
an individual Holder, or (c) acquires at least one hundred thousand (100,000)
shares of Registrable Securities (as adjusted for stock splits and
combinations); provided, however, (i) the transferor shall, within ten (10) days
after such transfer, furnish to the Company written notice of the name and
address of such transferee or assignee and the securities with respect to which
such registration rights are being assigned and (ii) such transferee shall agree
to be subject to all restrictions set forth in this Agreement.

     2.11 Amendment of Registration Rights.  Any provision of this Section 2 may
be amended and the observance thereof may be waived (either generally or in a
particular instance and either retroactively or prospectively), only with the
written consent of the Company and the Holders of at least a majority of the
Registrable Securities then outstanding.  Any amendment or waiver effected in
accordance with this Section 2.11 shall be binding upon each Holder and the

                                      11.
<PAGE>

Company.  By acceptance of any benefits under this Section 2, Holders of
Registrable Securities hereby agree to be bound by the provisions hereunder.

     2.12  Limitation on Subsequent Registration Rights. After the date of this
Agreement, the Company shall not, without the prior written consent of the
Holders of a majority of the Registrable Securities then outstanding, enter into
any agreement with any holder or prospective holder of any securities of the
Company that would grant such holder registration rights pari passu or senior to
those granted to the Holders hereunder.

     2.13   "Market Stand-Off" Agreement; Agreement to Furnish Information. Each
Holder hereby agrees that such Holder shall not sell, transfer, make any short
sale of, grant any option for the purchase of, or enter into any hedging or
similar transaction with the same economic effect as a sale, any Common Stock
(or other securities) of the Company held by such Holder (other than those
included in the registration) for a period specified by the representative of
the underwriters of Common Stock (or other securities) of the Company not to
exceed one hundred eighty (180) days following the effective date of a
registration statement of the Company filed under the Securities Act; provided
that:

            (a)  such agreement shall apply only to the Company's Initial
Offering;

            (b)  all officers and directors of the Company enter into similar
agreements;

            (c)  such agreement shall not apply to the purchase or sale of
Common Stock (or other securities registered by the Company) acquired in the
Company's Initial Offering (other than any shares that are purchased in the
Initial Offering as part of a directed share program) or on the open market
after the Company's Initial Offering by ATGF II.

            Each Holder agrees to execute and deliver such other agreements as
may be reasonably requested by the Company or the underwriter which are
consistent with the foregoing or which are necessary to give further effect
thereto. In addition, if requested by the Company or the representative of the
underwriters of Common Stock (or other securities) of the Company, each Holder
shall provide, within ten (10) days of such request, such information as may be
required by the Company or such representative in connection with the completion
of any public offering of the Company's securities pursuant to a registration
statement filed under the Securities Act. The obligations described in this
Section 2.13 shall not apply to a registration relating solely to employee
benefit plans on Form S-1 or Form S-8 or similar forms that may be promulgated
in the future, or a registration relating solely to a Commission Rule 145
transaction on Form S-4 or similar forms that may be promulgated in the future.
The Company may impose stop-transfer instructions with respect to the shares of
Common Stock (or other securities) subject to the foregoing restriction until
the end of said one hundred eighty (180) day period.

     2.14   Rule 144 Reporting. With a view to making available to the Holders
the benefits of certain rules and regulations of the SEC which may permit the
sale of the Registrable Securities to the public without registration, the
Company agrees to use its best efforts to:

            (a)  Make and keep public information available, as those terms are
understood and defined in SEC Rule 144 or any similar or analogous rule
promulgated under the

                                      12.
<PAGE>

Securities Act, at all times after the effective date of the first registration
filed by the Company for an offering of its securities to the general public;

            (b)  File with the SEC, in a timely manner, all reports and other
documents required of the Company under the Exchange Act; and

            (c)  So long as a Holder owns any Registrable Securities, furnish to
such Holder forthwith upon request: a written statement by the Company as to its
compliance with the reporting requirements of said Rule 144 of the Securities
Act, and of the Exchange Act (at any time after it has become subject to such
reporting requirements); a copy of the most recent annual or quarterly report of
the Company; and such other reports and documents as a Holder may reasonably
request in availing itself of any rule or regulation of the SEC allowing it to
sell any such securities without registration.

SECTION 3.  COVENANTS OF THE COMPANY

     3.1    Basic Financial Information and Reporting.

            (a)  The Company will maintain true books and records of account in
which full and correct entries will be made of all its business transactions
pursuant to a system of accounting established and administered in accordance
with generally accepted accounting principles consistently applied, and will set
aside on its books all such proper accruals and reserves as shall be required
under generally accepted accounting principles consistently applied.

            (b)  As soon as practicable after the end of each fiscal year of the
Company, and in any event within one hundred twenty (120) days thereafter, the
Company will furnish to each Investor a balance sheet of the Company, as at the
end of such fiscal year, and a statement of income and a statement of cash flows
of the Company, for such year, all prepared in accordance with generally
accepted accounting principles consistently applied and setting forth in each
case in comparative form the figures for the previous fiscal year, all in
reasonable detail. Such financial statements shall be accompanied by a report
and opinion thereon by independent public accountants of national standing
selected by the Company's Board of Directors.

            (c)  The Company will furnish each Investor, as soon as practicable
after the end of the first, second and third quarterly accounting periods in
each fiscal year of the Company, and in any event within forty-five (45) days
thereafter, a balance sheet of the Company as of the end of each such quarterly
period, and a statement of income and a statement of cash flows of the Company
for such period and for the current fiscal year to date, prepared in accordance
with generally accepted accounting principles, with the exception that no notes
need be attached to such statements and year-end audit adjustments may not have
been made.

            (d)  So long as an Investor (with its Affiliates) shall own not less
than one million (1,000,000) shares of Registrable Securities (as adjusted for
stock splits, combinations and the like) (a "Major Investor"), the Company will
furnish each such Major Investor requesting such information as soon as
practicable after the end of each month, and in any event within twenty-one (21)
days thereafter, a balance sheet of the Company as of the end of each such month
and a statement of income and a statement of cash flows of the Company for such
month and for the current fiscal year to date prepared in accordance with
generally accepted

                                      13.
<PAGE>

accounting principles consistently applied, with the exception that no notes
need be attached to such statements and year-end audit adjustments may not have
been made.

     3.2    Inspection Rights. Each Major Investor shall have the right to visit
and inspect any of the properties of the Company or any of its subsidiaries, and
to discuss the affairs, finances and accounts of the Company or any of its
subsidiaries with its officers, and to review such information as is reasonably
requested all at such reasonable times and as often as may be reasonably
requested; provided, however, that the Company shall not be obligated under this
Section 3.2 with respect to a competitor of the Company or with respect to
information which the Board of Directors determines in good faith is
confidential and should not, therefore, be disclosed.

     3.3    Confidentiality of Records. Each Investor agrees to use, and to use
its best efforts to insure that its authorized representatives use, the same
degree of care as such Investor uses to protect its own confidential information
to keep confidential any information furnished to it which the Company
identifies as being confidential or proprietary (so long as such information is
not in the public domain), except that such Investor may disclose such
proprietary or confidential information to any partner, subsidiary or parent of
such Investor for the purpose of evaluating its investment in the Company as
long as such partner, subsidiary or parent is advised of the confidentiality
provisions of this Section 3.3.

     3.4    Reservation of Common Stock. The Company will at all times reserve
and keep available, solely for issuance and delivery upon the conversion of the
Preferred Stock, all Common Stock issuable from time to time upon such
conversion.

     3.5    Stock Vesting. Unless otherwise approved by the Board of Directors,
all stock options and other stock equivalents issued after the date of this
Agreement to employees, directors, consultants and other service providers shall
be subject to vesting as follows: (a) twenty-five percent (25%) of such stock
shall vest at the end of the first year following the earlier of the date of
issuance or such person's services commencement date with the company, and (b)
seventy-five percent (75%) of such stock shall vest over the remaining three (3)
years. With respect to any shares of stock purchased by any such person, the
Company's repurchase option shall provide that upon such person's termination of
employment or service with the Company, with or without cause, the Company or
its assignee (to the extent permissible under applicable securities laws and
other laws) shall have the option to purchase at cost any unvested shares of
stock held by such person.

     3.6    Proprietary Information and Inventions Agreement. The Company shall
require all employees to execute and deliver a Proprietary Information and
Inventions Agreement in the form attached to the Purchase Agreement. The Company
shall require all consultants to execute and deliver an agreement containing
confidentiality and other reasonably protective provisions for the Company under
the circumstances.

     3.7    Assignment of Right of First Refusal. In the event the Company
elects not to exercise any right of first refusal or right of first offer the
Company may have on a proposed transfer of any of the Company's outstanding
capital stock pursuant to the Company's charter documents, by contract or
otherwise, the Company shall, to the extent it may do so, assign such

                                      14.
<PAGE>

right of first refusal or right of first offer to each Major Investor. In the
event of such assignment, each Major Investor shall have a right to purchase its
pro rata portion (as defined in Section 4.1) of the capital stock proposed to be
transferred.

     3.8    Termination of Covenants. All covenants of the Company contained in
Section 3 of this Agreement shall expire and terminate as to each Investor upon
the earlier of (i) the effective date of the registration statement pertaining
to the Initial Offering or (ii) upon (a) the sale, lease or other disposition of
all or substantially all of the assets of the Company or (b) an acquisition of
the Company by another corporation or entity by consolidation, merger or other
reorganization in which the holders of the Company's outstanding voting stock
immediately prior to such transaction own, immediately after such transaction,
securities representing less than fifty percent (50%) of the voting power of the
corporation or other entity surviving such transaction, provided that this
Section 3.8(ii)(b) shall not apply to a merger effected exclusively for the
purpose of changing the domicile of the Company (a "Change in Control").

SECTION 4.  RIGHTS OF FIRST REFUSAL

     4.1    Subsequent Offerings. So long as an Investor (with its Affiliates)
shall own not less than three hundred thousand (300,000) shares of Registrable
Securities (as adjusted for stock splits and combinations and the like) (a
"Significant Investor"), each such Significant Investor shall have a right of
first refusal to purchase its pro rata share of all Equity Securities, as
defined below, that the Company may, from time to time, propose to sell and
issue after the date of this Agreement, other than the Equity Securities
excluded by Section 4.7 hereof. Each Investor's pro rata share is equal to the
ratio of (a) the number of shares of the Company's Common Stock (including all
shares of Common Stock issued or issuable upon conversion of the Shares) which
such Investor is deemed to be a holder immediately prior to the issuance of such
Equity Securities to (b) the total number of shares of the Company's outstanding
Common Stock (including all shares of Common Stock issued or issuable upon
conversion of the Shares or upon the exercise of any outstanding warrants or
options) immediately prior to the issuance of the Equity Securities. The term
"Equity Securities" shall mean (i) any Common Stock, Preferred Stock or other
security of the Company, (ii) any security convertible, with or without
consideration, into any Common Stock, Preferred Stock or other security
(including any option to purchase such a convertible security), (iii) any
security carrying any warrant or right to subscribe to or purchase any Common
Stock, Preferred Stock or other security or (iv) any such warrant or right.

     4.2    Exercise of Rights. If the Company proposes to issue any Equity
Securities, it shall give each Significant Investor written notice of its
intention, describing the Equity Securities, the price and the terms and
conditions upon which the Company proposes to issue the same. Each Significant
Investor shall have fifteen (15) days from the giving of such notice to agree to
purchase its pro rata share of the Equity Securities for the price and upon the
terms and conditions specified in the notice by giving written notice to the
Company and stating therein the quantity of Equity Securities to be purchased.
Notwithstanding the foregoing, the Company shall not be required to offer or
sell such Equity Securities to any Significant Investor who would cause the
Company to be in violation of applicable federal securities laws by virtue of
such offer or sale.

                                      15.

     4.3    Issuance of Equity Securities to Other Persons. If not all of the
Significant Investors elect to purchase their pro rata share of the Equity
Securities, then the Company shall promptly notify in writing the Significant
Investors who do so elect and shall offer such Significant Investors the right
to acquire such unsubscribed shares. The Significant Investors shall have five
(5) days after receipt of such notice to notify the Company of its election to
purchase all or a portion thereof of the unsubscribed shares. If the Significant
Investors fail to exercise in full the rights of first refusal, the Company
shall have ninety (90) days thereafter to sell the Equity Securities in respect
of which the Significant Investor's rights were not exercised, at a price and
upon general terms and conditions materially no more favorable to the purchasers
thereof than specified in the Company's notice to the Significant Investors
pursuant to Section 4.2 hereof. If the Company has not sold such Equity
Securities within ninety (90) days of the notice provided pursuant to Section
4.2, the Company shall not thereafter issue or sell any Equity Securities,
without first offering such securities to the Significant Investors in the
manner provided above.

     4.4    Sale Without Notice. In lieu of giving notice to the Significant
Investors prior to the issuance of Equity Securities as provided in Section 4.2,
the Company may elect to give notice to the Significant Investors within thirty
(30) days after the issuance of Equity Securities. Such notice shall describe
the type, price and terms of the Equity Securities. Each Significant Investor
shall have twenty (20) days from the date of receipt of such notice to elect to
purchase its pro rata share of Equity Securities (as defined in Section 4.1, and
calculated before giving effect to the sale of the Equity Securities to the
purchasers thereof). The closing of such sale shall occur within sixty (60) days
of the date of notice to the Significant Investors.

     4.5    Termination and Waiver of Rights of First Refusal. The rights of
first refusal established by this Section 4 shall not apply to, and shall
terminate upon the earlier of (i) the effective date of the registration
statement pertaining to the Company's Initial Offering or (ii) a Change in
Control. The rights of first refusal established by this Section 4 may be
amended, or any provision waived with the written consent of Significant
Investors holding a majority of the Registrable Securities held by all
Significant Investors, or as permitted by Section 5.6.

     4.6    Transfer of Rights of First Refusal. The rights of first refusal of
each Significant Investor under this Section 4 may be transferred to the same
parties, subject to the same restrictions as any transfer of registration rights
pursuant to Section 2.10.

     4.7    Excluded Securities. The rights of first refusal established by this
Section 4 shall have no application to any of the following Equity Securities:

            (a)  shares of Common Stock (and/or options, warrants or other
Common Stock purchase rights issued pursuant to such options, warrants or other
rights) issued or to be issued after the Original Issue Date (as defined in the
Company's Certificates of Incorporation) to employees, officers or directors of,
or consultants or advisors to the Company or any subsidiary, pursuant to stock
purchase or stock option plans or other arrangements that are approved by the
Board of Directors;

            (b)  stock issued pursuant to any rights or agreements outstanding
as of the date of this Agreement, options and warrants outstanding as of the
date of this Agreement, and

                                      16.
<PAGE>

stock issued pursuant to any such rights or agreements granted after the date of
this Agreement; provided that the rights of first refusal established by this
Section 4 applied with respect to the initial sale or grant by the Company of
such rights or agreements;

            (c)  any Equity Securities issued for consideration other than cash
pursuant to a merger, consolidation, acquisition or similar business
combination;

            (d)  shares of Common Stock issued in connection with any stock
split, stock dividend or recapitalization by the Company;

            (e)  shares of Common Stock issued upon conversion of the Shares;

            (f)  any Equity Securities issued pursuant to any equipment leasing
or loan arrangement, or debt financing from a bank or similar financial or
lending institution;

            (g)  any Equity Securities that are issued by the Company pursuant
to a registration statement filed under the Securities Act; and

            (h)  shares of the Company's Common Stock or Preferred Stock issued
in connection with strategic transactions involving the Company and other
entities, including (i) joint ventures, manufacturing, marketing or distribution
arrangements or (ii) technology transfer or development arrangements; provided
that such strategic transactions and the issuance of shares therein, has been
approved by the Company's Board of Directors.

                               CO-SALE AGREEMENT

     This Co-Sale Agreement (the "Agreement") is made and entered into as of
this 30th day of September, 1999, by and among Mercata, Inc., a Delaware
corporation (the "Company"), each of the persons and entities listed on Exhibit
A hereto (the "Investors"), and Vulcan Ventures Incorporated (referred to herein
as the "Founder").

                                    Recitals

     Whereas, the Founder is the beneficial owner of an aggregate of one million
(1,000,000) shares of Common Stock of the Company, fourteen million (14,000,000)
shares of Series A Preferred Stock of the Company and one million eight hundred
eighty-eight thousand (1,888,000) shares of Series B Preferred Stock of the
Company;

     Whereas, Investors are purchasing shares of the Company's Series B
Preferred Stock (the "Series B Preferred Stock") pursuant to that certain Series
B Preferred Stock Purchase Agreement (the "Purchase Agreement") of even date
herewith;

     Whereas, such Investors were induced by the Company to purchase the Series
B Preferred Stock in part by the Company's and the Founder's agreement to enter
into this Agreement; and

     Whereas, the parties desire to enter into this Agreement in order to grant
rights of co-sale to each Investor.

     Now, Therefore, in consideration of the mutual promises, representations,
warranties, covenants and conditions set forth in this Agreement and the
Purchase Agreement and for other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the parties agree hereto as
follows:

     1.   Definitions.

          (a)  "Co-Sale Stock" shall mean shares of the Company's Common Stock
and Preferred Stock now owned or subsequently acquired by the Founder by gift,
purchase, dividend, option exercise or any other means whether or not such
securities are only registered in a Founder's name or beneficially or legally
owned by Founder, including any interest of a spouse in any of the Co-Sale
Stock, whether that interest is asserted pursuant to marital property laws or
otherwise. The number of shares of Co-Sale Stock owned by the Founder as of the
date hereof are set forth on Exhibit B, which Exhibit may be amended from time
to time by the Company to reflect changes in the number of shares owned by the
Founder, but the failure to so amend shall have no effect on such Co-Sale Stock
being subject to this Agreement.

          (b)  "Common Stock" shall mean the Company's Common Stock and shares
of Common Stock issued or issuable upon exercise of any option, warrant or other
security or right of any kind convertible into or exchangeable for Common Stock.

                                      1.
<PAGE>

          (c)  "Preferred Stock" shall mean the Company's Preferred Stock and
shares of Preferred Stock issued or issuable upon exercise of any option,
warrant or other security or right of any kind convertible into or exchangeable
for Preferred Stock.

          (d)  For the purpose of this Agreement, the term "Transfer" shall
include any sale, assignment, encumbrance, hypothecation, pledge, conveyance in
trust, gift, transfer by request, devise or descent, or other transfer or
disposition of any kind, including, but not limited to, transfers to receivers,
levying creditors, trustees or receivers in bankruptcy proceedings or general
assignees for the benefit of creditors, whether voluntary or by operation of
law, directly or indirectly, of any of the Co-Sale Stock.

          (e)  "Affiliate" of a person or entity means any person or entity who
controls, is controlled by or under common control with such person or entity.

     2.   Transfers by a Founder.

          (a)  If the Founder proposes to Transfer any shares of Co-Sale Stock
then the Founder shall promptly give written notice (the "Notice")
simultaneously to the Company and to each of the Investors at least thirty (30)
days prior to the closing of such Transfer. The Notice shall describe in
reasonable detail the proposed Transfer including, without limitation, the
number of shares of Co-Sale Stock to be transferred, the nature of such
Transfer, the consideration to be paid, and the name and address of each
prospective purchaser or transferee. In the event that the Transfer is being
made pursuant to the provisions of Section 3(a), the Notice shall state under
which section the Transfer is being made.

          (b)  Each Investor shall have the right, exercisable upon written
notice to the Founder within fifteen (15) days after the Notice, to participate
in such Transfer of Co-Sale Stock on the same terms and conditions. Such notice
shall indicate the number of shares of Common Stock and/or Preferred Stock such
Investor wishes to sell under his or her right to participate. To the extent one
or more of the Investors exercise such right of participation in accordance with
the terms and conditions set forth below, the number of shares of Co-Sale Stock
that the Founder may sell in the transaction shall be correspondingly reduced.

          (c)  Each Investor may sell all or any part of that number of shares
equal to the product obtained by multiplying (i) the aggregate number of shares
of Co-Sale Stock covered by the Notice by (ii) a fraction the numerator of which
is the number of shares of Common Stock (including shares of Preferred Stock on
an as converted basis) owned by such Investor at the time of the Transfer and
the denominator of which is the total number of shares of Common Stock
(including shares of Preferred Stock on an as converted basis) owned by Founder
and the Investors at the time of the Transfer.

          (d)  Each Investor who elects to participate in the Transfer pursuant
to this Section 2 (a "Participant") shall effect its participation in the
Transfer by promptly delivering to Founder for transfer to the prospective
purchaser one or more certificates, properly endorsed for transfer, which
represent:

               (i)   the type and number of shares of Common Stock and/or
Preferred Stock which such Participant elects to sell; or

                                      2.
<PAGE>

               (ii)  that number of shares of Preferred Stock which is at such
time convertible into the number of shares of Common Stock which such
Participant elects to sell; provided, however, that if the prospective purchaser
objects to the delivery of Preferred Stock in lieu of Common Stock, such
Participant shall convert such Preferred Stock into Common Stock and deliver
Common Stock as provided in Section 2(d)(i) above. The Company agrees to make
any such conversion concurrent with the actual transfer of such shares to the
purchaser.

          (e)  The stock certificate or certificates that the Participant
delivers to Founder pursuant to Section 2(d) shall be transferred to the
prospective purchaser in consummation of the sale of the Common Stock pursuant
to the terms and conditions specified in the Notice, and the Founder shall
concurrently therewith remit to such Participant that portion of the sale
proceeds to which such Participant is entitled by reason of its participation in
such sale. To the extent that any prospective purchaser or purchasers prohibits
such assignment or otherwise refuses to purchase shares or other securities from
a Participant exercising its rights of co-sale hereunder, the Founder shall not
sell to such prospective purchaser or purchasers any Co-Sale Stock unless and
until, simultaneously with such sale, the Founder shall purchase such shares or
other securities from such Participant on the same terms and conditions
specified in the Notice.

          (f)  The exercise or non-exercise of the rights of the Investors
hereunder to participate in one or more Transfers of Co-Sale Stock made by the
Founder shall not adversely affect their rights to participate in subsequent
Transfers of Co-Sale Stock subject to Section 2(a).

          (g)  If none of the Investors elect to participate in the sale of the
Co-Sale Stock subject to the Notice, the Founder may, not later than sixty (60)
days following delivery to the Company of the Notice, enter into an agreement
providing for the closing of the Transfer of the Co-Sale Stock covered by the
Notice within thirty (30) days of such agreement on terms and conditions not
more materially favorable to the transferor than those described in the Notice.
Any proposed transfer on terms and conditions materially more favorable than
those described in the Notice, as well as any subsequent proposed transfer of
any of the Co-Sale Stock by Founder, shall again be subject to the co-sale
rights of the Investors and shall require compliance by Founder with the
procedures described in this Section 2.

     3.   Exempt Transfers.

          (a)  Notwithstanding the foregoing, the co-sale rights of the
Investors shall not apply to (i) any transfer to the ancestors, descendants or
spouse or to trusts for the benefit of such persons or the Founder, (ii) any
transfer or transfers by a Founder to another Founder (the "Transferee-Founder")
so long as the Transferee-Founder is, at the time of the transfer, employed by
or acting as a consultant or director of the Company, (iii) any pledge of Co-
Sale Stock made pursuant to a bona fide loan transaction that creates a mere
security interest, (iv) any bona fide gift, or (v) any transfer to an Affiliate;
provided that in the event of any transfer made pursuant to one of the
exemptions provided above, (A) the Founder shall inform the Investors of such
pledge, transfer or gift prior to effecting it and (B) the pledgee, transferee
or donee shall furnish the Investors with a written agreement to be bound by and
comply with all provisions of Section 2. Except with respect to Co-Sale Stock
transferred under clause (i) above (which Co-Sale Stock shall no longer be
subject to the co-sale rights of the Investors), such transferred Co-

                                      3.
<PAGE>

Sale Stock shall remain "Co-Sale Stock" hereunder, and such pledgee, transferee
or donee shall be treated as the "Founder" for purposes of this Agreement.

          (b)  Notwithstanding the foregoing, the provisions of Section 2 shall
not apply to the sale of any Co-Sale Stock to the public pursuant to a
registration statement filed with, and declared effective by, the Securities and
Exchange Commission under the Securities Act of 1933, as amended (the
"Securities Act").

          (c)  This Agreement is subject to, and shall in no manner limit the
right which the Company may have to repurchase securities from the Founder
pursuant to (i) a stock restriction agreement or other agreement between the
Company and the Founder and (ii) any right of first refusal set forth in the
Bylaws of the Company.

     4.   Prohibited Transfers.

          (a)  In the event that Founder should Transfer any Co-Sale Stock in
contravention of the co-sale rights of each Investor under this Agreement (a
"Prohibited Transfer"), each Investor, in addition to such other remedies as may
be available at law, in equity or hereunder, shall have the put option provided
below, and the Founder shall be bound by the applicable provisions of such
option.

          (b)  In the event of a Prohibited Transfer, each Investor shall have
the right to sell to Founder the type and number of shares of Common Stock equal
to the number of shares each Investor would have been entitled to transfer to
the purchaser under Section 2(c) hereof had the Prohibited Transfer been
effected pursuant to and in compliance with the terms hereof. Such sale shall be
made on the following terms and conditions:

               (i)    The price per share at which the shares are to be sold to
the Founder shall be equal to the price per share paid by the purchaser to the
Founder in such Prohibited Transfer. The Founder shall also reimburse each
Investor for any and all fees and expenses, including legal fees and expenses,
incurred pursuant to the exercise or the attempted exercise of the Investor's
rights under Section 2.

               (ii)   Within ninety (90) days after the date on which an
Investor received notice of the Prohibited Transfer or otherwise became aware of
the Prohibited Transfer, such Investor shall, if exercising the option created
hereby, deliver to the Founder the certificate or certificates representing
shares to be sold, each certificate to be properly endorsed for transfer.

               (iii)  The Founder shall, upon receipt of the certificate or
certificates for the shares to be sold by an Investor, pursuant to this Section
4(b), pay the aggregate purchase price therefor and the amount of reimbursable
fees and expenses, as specified in Section 4(b)(i), in cash or by other means
acceptable to the Investor.

               (iv)   Notwithstanding the foregoing, any attempt by a Founder to
transfer Co-Sale Stock in violation of Section 2 hereof shall be voidable at the
option of a majority in interest of the Investors if the Investors do not elect
to exercise the put option set forth in this Section 4, and the Company agrees
it will not effect such a transfer nor will it treat

                                      4.
<PAGE>

any alleged transferee as the holder of such shares without the written consent
of a majority in interest of the Investors.

     5.   Legend.

          (a)  Each certificate representing shares of Co-Sale Stock now or
hereafter owned by the Founder or issued to any person in connection with a
transfer pursuant to Section 3(a) hereof shall be endorsed with the following
legend:

               "THE SALE, PLEDGE, HYPOTHECATION OR TRANSFER OF THE SECURITIES
     REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO THE TERMS AND CONDITIONS OF A
     CERTAIN CO-SALE AGREEMENT BY AND BETWEEN THE SHAREHOLDER, THE COMPANY AND
     CERTAIN HOLDERS OF STOCK OF THE COMPANY. COPIES OF SUCH AGREEMENT MAY BE
     OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF THE COMPANY."

          (b)  The Founder agrees that the Company may instruct its transfer
agent to impose transfer restrictions on the shares represented by certificates
bearing the legend referred to in Section 5(a) above to enforce the provisions
of this Agreement and the Company agrees to promptly do so. The legend shall be
removed upon termination of this Agreement.

shall not affect any other provisions of this Agreement, and this Agreement
shall be construed as if such invalid, illegal or unenforceable provision had
never been contained herein.

     3.5   Successors.  This Agreement shall inure to the benefit of and be
binding upon the parties hereto and their respective heirs, successors, assigns,
administrators, executors and other legal representatives.

deemed to be Investor Shares for purposes of this Agreement.

an additional counterpart signature page to this Agreement and shall be deemed
an "Investor" hereunder.

                                 MERCATA, INC.

                       EMPLOYEE PROPRIETARY INFORMATION
                           AND INVENTIONS AGREEMENT

     In consideration of my employment or continued employment by Mercata, Inc.
(the "Company"), and the compensation now and hereafter paid to me, I hereby
agree as follows:

1.   Nondisclosure

     1.1  Recognition of Company's Rights; Nondisclosure. At all times during my
employment and thereafter, I will hold in strictest confidence and will not
disclose, use, lecture upon or publish any of the Company's Proprietary
Information (defined below), except as such disclosure, use or publication may
be required in connection with my work for the Company, or unless an officer of
the Company expressly authorizes such in writing. I will obtain Company's
written approval before publishing or submitting for publication any material
(written, verbal, or otherwise) that relates to my work at Company and/or
incorporates any Proprietary Information. I hereby assign to the Company any
rights I may have or acquire in such Proprietary Information and recognize that
all Proprietary Information shall be the sole property of the Company and its
assigns.

     1.2  Proprietary Information. The term "Proprietary Information" shall mean
any and all confidential and/or proprietary knowledge, data or information of
the Company. By way of illustration but not limitation, "Proprietary
Information" includes (a) trade secrets, inventions, mask works, ideas,
processes, formulas, source and object codes, data, programs, other works of
authorship, know-how, improvements, discoveries, developments, designs and
techniques (hereinafter collectively referred to as "Inventions"); and (b)
information regarding plans for research, development, new products, marketing
and selling, business plans, budgets and unpublished financial statements,
licenses, prices and costs, suppliers and customers; and (c) information
regarding the skills and compensation of other employees of the Company.
Notwithstanding the foregoing, it is understood that, at all such times, I am
free to use information which is generally known in the trade or industry, which
is not gained as result of a breach of this Agreement, and my own, skill,
knowledge, know-how and experience to whatever extent and in whichever way I
wish.

     1.3  Third Party Information.  I understand, in addition, that the Company
has received and in the future will receive from third parties confidential or
proprietary information ("Third Party Information") subject to a duty on the
Company's part to maintain the confidentiality of such information and to use it
only for certain limited purposes.  During the term of my employment and
thereafter, I will hold Third Party Information in the strictest confidence and
will not disclose to anyone (other than Company personnel who need to know such
information in connection with their work for the Company) or use, except in
connection with my work for the Company, Third Party Information unless
expressly authorized by an officer of the Company in writing.

     1.4  No Improper Use of Information of Prior Employers and Others. During
my employment by the Company I will not improperly use or disclose any
confidential information or trade secrets, if any, of any former employer or any
other person to whom I have an obligation of confidentiality, and I will not
bring onto the premises of the Company any unpublished documents or any property
belonging to any former employer or any other person to whom I have an
obligation of confidentiality unless consented to in writing by that former
employer or person. I will use in the performance of my duties only information
which is generally known and used by persons with training and experience
comparable to my own, which is common knowledge in the industry or otherwise
legally in the public domain, or which is otherwise provided or developed by the
Company.

2.   Assignment of Inventions.

     2.1  Proprietary Rights. The term "Proprietary Rights" shall mean all trade
secret, patent, copyright, mask work and other intellectual property rights
throughout the world.

     2.2  Prior Inventions.  Inventions, if any, patented or unpatented, which I
made prior to the commencement of my employment with the Company are excluded
from the scope of this Agreement.  To preclude any possible uncertainty, I have
set forth on Exhibit A (Previous Inventions) attached hereto a complete list of
all Inventions that I have, alone or jointly with others, conceived, developed
or reduced

                                      1.
<PAGE>

to practice or caused to be conceived, developed or reduced to practice prior to
the commencement of my employment with the Company, that I consider to be my
property or the property of third parties and that I wish to have excluded from
the scope of this Agreement (collectively referred to as "Prior Inventions"). If
disclosure of any such Prior Invention would cause me to violate any prior
confidentiality agreement, I understand that I am not to list such Prior
Inventions in Exhibit A but am only to disclose a cursory name for each such
invention, a listing of the party(ies) to whom it belongs and the fact that full
disclosure as to such inventions has not been made for that reason. A space is
provided on Exhibit A for such purpose. If no such disclosure is attached, I
represent that there are no Prior Inventions. If, in the course of my employment
with the Company, I incorporate a Prior Invention into a Company product,
process or machine, the Company is hereby granted and shall have a nonexclusive,
royalty-free, irrevocable, perpetual, worldwide license (with rights to
sublicense through multiple tiers of sublicensees) to make, have made, modify,
use and sell such Prior Invention. Notwithstanding the foregoing, I agree that I
will not incorporate, or permit to be incorporated, Prior Inventions in any
Company Inventions without the Company's prior written consent.

     2.3  Assignment of Inventions.  Subject to Sections 2.4, and 2.6, I hereby
assign and agree to assign in the future (when any such Inventions or
Proprietary Rights are first reduced to practice or first fixed in a tangible
medium, as applicable) to the Company all my right, title and interest in and to
any and all Inventions (and all Proprietary Rights with respect thereto) whether
or not patentable or registrable under copyright or similar statutes, made or
conceived or reduced to practice or learned by me, either alone or jointly with
others, during the period of my employment with the Company.  Inventions
assigned to the Company, or to a third party as directed by the Company pursuant
to this Section 2, are hereinafter referred to as "Company Inventions."

     2.4  Nonassignable Inventions.  I recognize that, my obligation to assign
shall not apply to any Invention about which I can prove that: (i) it was
developed entirely on my own time; and (ii) no equipment, supplies, facility,
services, or trade secret information of the Company was used in its
development; and (iii) it does not relate (a) directly to the business of the
Company or (b) to the actual or demonstrably anticipated research or development
of the Company; and (iv) it does not result from any work performed by me for
the Company (a "Nonassignable Invention").

     2.5  Obligation to Keep Company Informed. During the period of my
employment and for six (6) months after termination of my employment with the
Company, I will promptly disclose to the Company fully and in writing all
Inventions authored, conceived or reduced to practice by me, either alone or
jointly with others. In addition, I will promptly disclose to the Company all
patent applications filed by me or on my behalf within a year after termination
of employment. At the time of each such disclosure, I will advise the Company in
writing of any Inventions that I believe fully qualify as a Nonassignable
Invention; and I will at that time provide to the Company in writing all
evidence necessary to substantiate that belief. The Company will keep in
confidence and will not use for any purpose or disclose to third parties without
my consent any confidential information disclosed in writing to the Company
pursuant to this Agreement relating to Nonassignable Inventions. I will preserve
the confidentiality of any Invention that does not fully qualify as a
Nonassignable Invention.

     2.6  Government or Third Party.  I also agree to assign all my right, title
and interest in and to any particular Company Invention to a third party,
including without limitation the United States, as directed by the Company.

     2.7  Works for Hire.  I acknowledge that all original works of authorship
which are made by me (solely or jointly with others) within the scope of my
employment and which are protectable by copyright are "works made for hire,"
pursuant to United States Copyright Act (17 U.S.C., Section 101).

     2.8  Enforcement of Proprietary Rights.  I will assist the Company in every
proper way to obtain, and from time to time enforce, United States and foreign
Proprietary Rights relating to Company Inventions in any and all countries.  To
that end I will execute, verify and deliver such documents and perform such
other acts (including appearances as a witness) as the Company may reasonably
request for use in applying for, obtaining, perfecting, evidencing, sustaining
and enforcing such Proprietary Rights and the assignment thereof.  In addition,
I will execute, verify and deliver assignments of such Proprietary Rights to the
Company or its designee.  My obligation to assist the Company with respect to
Proprietary Rights relating to such Company Inventions in any and all countries
shall continue beyond the termination of my employment, but the Company shall
compensate me at a reasonable rate after my termination for the time actually
spent by me at the Company's request on such assistance.

                                      2.
<PAGE>

In the event the Company is unable for any reason, after reasonable effort, to
secure my signature on any document needed in connection with the actions
specified in the preceding paragraph, I hereby irrevocably designate and appoint
the Company and its duly authorized officers and agents as my agent and attorney
in fact, which appointment is coupled with an interest, to act for and in my
behalf to execute, verify and file any such documents and to do all other
lawfully permitted acts to further the purposes of the preceding paragraph with
the same legal force and effect as if executed by me.  I hereby waive and
quitclaim to the Company any and all claims, of any nature whatsoever, which I
now or may hereafter have for infringement of any Proprietary Rights assigned
hereunder to the Company.

3.   Records.  I agree to keep and maintain adequate and current records (in the
form of notes, sketches, drawings and in any other form that may be required by
the Company) of all Proprietary Information developed by me and all Inventions
made by me during the period of my employment at the Company, which records
shall be available to and remain the sole property of the Company at all times.

4.   Additional Activities.  I agree that during the period of my employment by
the Company I will not, without the Company's express written consent, engage in
any employment or business activity which is competitive with, or would
otherwise conflict with, my employment by the Company.  I agree further that for
the period of my employment by the Company and for one (l) year after the date
of termination of my employment by the Company I will not induce any employee of
the Company to leave the employ of the Company.

5.   No Conflicting Obligation. I represent that my performance of all the terms
of this Agreement and as an employee of the Company does not and will not breach
any agreement to keep in confidence information acquired by me in confidence or
in trust prior to my employment by the Company. I have not entered into, and I
agree I will not enter into, any agreement either written or oral in conflict
herewith.

6.   Return of Company Documents. When I leave the employ of the Company, I will
deliver to the Company any and all drawings, notes, memoranda, specifications,
devices, formulas, and documents, together with all copies thereof, and any
other material containing or disclosing any Company Inventions, Third Party
Information or Proprietary Information of the Company. I further agree that any
property situated on the Company's premises and owned by the Company, including
disks and other storage media, filing cabinets or other work areas, is subject
to inspection by Company personnel at any time with or without notice. Prior to
leaving, I will cooperate with the Company in completing and signing the
Company's termination statement.

7.   Legal and Equitable Remedies.  Because my services are personal and unique
and because I may have access to and become acquainted with the Proprietary
Information of the Company, the Company shall have the right to enforce this
Agreement and any of its provisions by injunction, specific performance or other
equitable relief, without bond and without prejudice to any other rights and
remedies that the Company may have for a breach of this Agreement.

8.   Notices.  Any notices required or permitted hereunder shall be given to the
appropriate party at the address specified below or at such other address as the
party shall specify in writing.  Such notice shall be deemed given upon personal
delivery to the appropriate address or if sent by certified or registered mail,
three (3) days after the date of mailing.

9.   Notification of New Employer.  In the event that I leave the employ of the
Company, I hereby consent to the notification of my new employer of my rights
and obligations under this Agreement.

10.  General Provisions.

     10.1 Governing Law; Consent to Personal Jurisdiction.  This Agreement will
be governed by and construed according to the laws of the State of Washington,
as such laws are applied to agreements entered into and to be performed entirely
within Washington between Washington residents.  I hereby expressly consent to
the personal jurisdiction of the state and federal courts located in King
County, Washington for any lawsuit filed there against me by Company arising
from or related to this Agreement.

     10.2 Severability.  In case any one or more of the provisions contained in
this Agreement shall, for any reason, be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect the other provisions of this Agreement, and this Agreement
shall be construed as if such invalid, illegal or unenforceable provision had
never been contained herein.  If moreover, any one or more of the provisions
contained in this Agreement shall for any reason be held to be excessively broad
as to duration, geographical scope, activity or subject, it shall be construed
by limiting and

                                      3.

<PAGE>

reducing it, so as to be enforceable to the extent compatible with the
applicable law as it shall then appear.

     10.3 Successors and Assigns.  This Agreement will be binding upon my heirs,
executors, administrators and other legal representatives and will be for the
benefit of the Company, its successors, and its assigns.

     10.4 Survival.  The provisions of this Agreement shall survive the
termination of my employment and the assignment of this Agreement by the Company
to any successor in interest or other assignee.

     10.5 Employment.  I agree and understand that nothing in this Agreement
shall confer any right with respect to continuation of employment by the
Company, nor shall it interfere in any way with my right or the Company's right
to terminate my employment at any time, with or without cause.

     10.6 Waiver.  No waiver by the Company of any breach of this Agreement
shall be a waiver of any preceding or succeeding breach.  No waiver by the
Company of any right under this Agreement shall be construed as a waiver of any
other right.  The Company shall not be required to give notice to enforce strict
adherence to all terms of this Agreement.

     10.7 Entire Agreement.  The obligations pursuant to Sections 1 and 2 of
this Agreement shall apply to any time during which I was previously employed,
or am in the future employed, by the Company as a consultant if no other
agreement governs nondisclosure and assignment of inventions during such period.
This Agreement is the final, complete and exclusive agreement of the parties
with respect to the subject matter hereof and supersedes and merges all prior
discussions between us.  No modification of or amendment to this Agreement, nor
any waiver of any rights under this Agreement, will be effective unless in
writing and signed by the party to be charged.  Any subsequent change or changes
in my duties, salary or compensation will not affect the validity or scope of
this Agreement.

     This Agreement shall be effective as of the first day of my employment with
the Company, namely:  _______________, 19__.

     I HAVE READ THIS AGREEMENT CAREFULLY AND UNDERSTAND ITS TERMS.  I HAVE
COMPLETELY FILLED OUT EXHIBIT A TO THIS AGREEMENT.

                             FORM OF LEGAL OPINION

Ladies and Gentlemen:

We have acted as counsel for Mercata, Inc., a Delaware corporation (the
"Company"), in connection with the issuance and sale of ________ shares of the
Company's Series B Preferred Stock ("Shares") to the Purchasers under the Series
B Preferred Stock Purchase Agreement dated as of _____________ (the
"Agreement").  We are rendering this opinion pursuant to Section 5.1(j) of the
Agreement.  Except as otherwise defined herein, capitalized terms used but not
defined herein have the respective meanings given to them in the Agreement.

In connection with this opinion, we have examined and relied upon the
representations and warranties as to factual matters contained in and made
pursuant to the Agreement by the various parties and originals or copies
certified to our satisfaction, of such records, documents, certificates,
opinions, memoranda and other instruments as in our judgment are necessary or
appropriate to enable us to render the opinion expressed below.  Where we render
an opinion "to the best of our knowledge" or concerning an item "known to us" or
our opinion otherwise refers to our knowledge, it is based solely upon (i) an
inquiry of attorneys within this firm who perform legal services for the
Company, (ii) receipt of a certificate executed by an officer of the Company
covering such matters, and (iii) such other investigation, if any, that we
specifically set forth herein.

In rendering this opinion, we have assumed:  the genuineness and authenticity of
all signatures on original documents; the authenticity of all documents
submitted to us as originals; the conformity to originals of all documents
submitted to us as copies; the accuracy, completeness and authenticity of
certificates of public officials; and the due authorization, execution and
delivery of all documents (except the due authorization, execution and delivery
by the Company of the Agreement, the Investor Rights Agreement, the Co-Sale
Agreement and the Voting Agreement (the "Transaction Agreements")), where
authorization, execution and delivery are prerequisites to the effectiveness of
such documents.  We have also assumed:  that all individuals executing and
delivering documents had the legal capacity to so execute and deliver; that you
have received all documents you were to receive under the Agreement; that the
Transaction Agreements are obligations binding upon you; and that there are no
extrinsic agreements or understandings among the parties to the Transaction
Agreements that would modify or interpret the terms of the Transaction
Agreements or the respective rights or obligations of the parties thereunder.

Our opinion is expressed only with respect to the federal laws of the United
States of America, the laws of the State of Washington and the General
Corporation Law of the State of Delaware. We express no opinion as to whether
the laws of any particular jurisdiction apply, and no opinion to the extent that
the laws of any jurisdiction other than those identified above are applicable to
the subject matter hereof.  We are not rendering any opinion as to compliance
with any antifraud law, rule or regulation relating to securities, or to the
sale or issuance thereof, or as to reportability of the sale of the Shares under
the Hart Scott Rodino Antitrust Improvements Act of 1976, as amended.
<PAGE>

With regard to our opinion in paragraph 2 below, we express no opinion as to the
obligation of the Company to qualify as a foreign corporation to do business in
the State of Pennsylvania.

With regard to our opinion in paragraph 4 below, we have examined and relied
upon a certificate executed by an officer of the Company, to the effect that the
consideration for all outstanding shares of capital stock of the Company was
received by the Company in accordance with the provisions of the applicable
Board of Directors resolutions and any plan or agreement relating to the
issuance of such shares, and we have undertaken no independent verification with
respect thereto.

On the basis of the foregoing, in reliance thereon and with the foregoing
qualifications, we are of the opinion that:

1.   The Company has been duly incorporated and is a validly existing
     corporation in good standing under the laws of the State of Delaware.

2.   The Company has the requisite corporate power to own its property and
     assets and to conduct its business as it is currently being conducted and,
     to the best of our knowledge, is qualified as a foreign corporation to do
     business and is in good standing in each jurisdiction in the United States
     in which the ownership of its property or the conduct of its business
     requires such qualification and where any statutory fines or penalties or
     any corporate disability imposed for the failure to qualify would
     materially and adversely affect the Company, its assets, financial
     condition or operations.

3.   The Transaction Agreements have been duly and validly authorized, executed
     and delivered by the Company and constitute valid and binding agreements of
     the Company enforceable against the Company in accordance with their terms,
     except as rights to indemnity under Section 2.9 of the Investor Rights
     Agreement may be limited by applicable laws and except as enforcement may
     be limited by applicable bankruptcy, insolvency, reorganization,
     arrangement, moratorium or other similar laws affecting creditors' rights,
     and subject to general equity principles and to limitations on availability
     of equitable relief, including specific performance.

4.   The Company's authorized capital stock consists of (a) forty million
     (40,000,000) shares of Common Stock, par value $0.001 per share, of which
     one million four hundred forty-four thousand fifty-eight (1,444,058) shares
     are issued and outstanding, and (b) thirty million (30,000,000) shares of
     Preferred Stock, par value $0.001 per share, fourteen million (14,000,000)
     of which have been designated Series A Preferred Stock, all of which are
     issued and outstanding, and twelve million (12,000,000) of which have been
     designated Series B Preferred Stock, none of which are issued and
     outstanding (excluding the Shares).  The outstanding shares of Common Stock
     and of Preferred Stock have been duly authorized and validly issued and are
     fully paid and non-assessable.  The rights, preferences and privileges of
     the Series A Preferred Stock and the Series B Preferred Stock are as stated
     in the Restated Certificate of Incorporation.  The Shares have been duly
     authorized, and upon issuance and delivery against payment therefor in
     accordance with the terms of the Agreement, the Shares will be validly
     issued, outstanding, fully paid
<PAGE>

     and non-assessable. The shares of Common Stock issuable upon conversion of
     the Shares have been duly authorized, and upon issuance and delivery upon
     conversion of the Shares, will be validly issued, outstanding, fully paid
     and non-assessable. To the best of our knowledge, there are no options,
     warrants, conversion privileges, preemptive rights or other rights
     presently outstanding to purchase any of the authorized but unissued
     capital stock of the Company, other than the conversion privileges of the
     Series A Preferred Stock, rights created in connection with the
     transactions contemplated by the Agreement, and seven million four hundred
     thousand (7,400,000) shares reserved for issuance under the Company's 1999
     Equity Incentive Plan.

5.   The execution and delivery of the Agreement by the Company and the issuance
     of the Shares pursuant thereto do not violate any provision of the
     Company's Certificate of Incorporation or Bylaws.

6.   To the best of our knowledge, there is no action, proceeding or
     investigation pending or overtly threatened against the Company before any
     court or administrative agency that questions the validity of the
     Transaction Agreements or might result, either individually or in the
     aggregate, in any material adverse change in the assets, financial
     condition, or operations of the Company that has not been disclosed in
     writing to the Investors.

7.   All consents, approvals, authorizations, or orders of, and filings,
     registrations, and qualifications with any regulatory authority or
     governmental body in the United States required for the consummation by the
     Company of the transactions contemplated by the Agreement, have been made
     or obtained, except for the filing of a Form D pursuant to Securities and
     Exchange Commission Regulation D and the filings required by the securities
     laws of the state of Washington.

8.   The offer and sale of the Shares are exempt from the registration
     requirements of the Securities Act of 1933, as amended.

                          CONVERTIBLE PROMISSORY NOTE


$[Amount]                                                     September 30, 1999
                                                            Bellevue, Washington

     For value received, Mercata, Inc., a Delaware corporation (the "Company"),
promises to pay to ____________________ (the "Holder"), the principal sum of
____________________ Dollars ($__________).  No interest shall accrue or be paid
on this Note; provided, that if this Note shall not have converted in accordance
with Section 2 below on or before November 30, 1999, this Note shall bear
interest accruing from the date hereof on the unpaid principal amount at a rate
equal to the lower of (a) 7.00% per annum, compounded annually or (b) the
highest rate permitted by law.  This Note is one of a series of Convertible
Promissory Notes containing substantially identical terms and conditions issued
pursuant to that certain Series B Preferred Stock Purchase Agreement, dated
September 30, 1999 (the "Purchase Agreement").  Such Notes are referred to
herein as the "Notes," and the holders thereof are referred to herein as the
"Holders."  This Note is subject to the following terms and conditions.

     1.  Maturity.  Unless converted as provided in Section 2, this Note will
automatically mature and be due and payable on November 30, 1999 (the "Maturity
Date").  Subject to Section 2 below, any interest shall accrue on this Note but
shall not be due and payable until the Maturity Date.

     2.  Conversion

         (A) HSR Clearance. As soon as practicable after the Closing (as defined
in the Purchase Agreement), the Company and the Holder hereby agree to file or
to cause to be filed with the United States Federal Trade Commission (the "FTC")
and the Antitrust Division of the United States Department of Justice (the
"DOJ") pursuant to the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended (the "HSR Act") all requisite documents and notifications in order to
provide for the conversion of this Note into shares of the Company's Series B
Preferred Stock. Upon the earlier of one business day after (i) the date all
required clearances or pre-termination notices under the HSR Act have been
received from the FTC and the DOJ (or all applicable waiting periods have
expired) or (ii) the date the Holder and the Company are no longer required by
law to make filings under the HSR to convert this Note into capital stock, the
entire principal amount of this Note shall automatically convert into fully-paid
and non-assessable shares of the Company's Series B Preferred Stock (the
"Stock"); provided, however, the automatic conversion of such principal amount
into shares of the Company's

                                       1.
<PAGE>

Series B Preferred Stock shall be conditioned upon (A) the Company having
provided to the Holder a compliance certificate in the form attached hereto as
Exhibit A or (B) the Holder having waived such applicable terms, conditions or
certifications included in such certificate, either individually or in the
aggregate. The number of shares of Stock to be issued upon such conversion shall
be equal to the quotient obtained by dividing (i) the entire outstanding
principal amount of this Note by (ii) $3.125 (as adjusted for any future stock
splits, stock dividends, recapitalizations or the like to the Stock), provided
that no fractional shares shall be issued. In the event that the required
clearances from the FTC and the DOJ are not obtained, this Note shall not be
convertible into the Stock.

          (b)  Redemption. In the event the Company consummates a Liquidity
Event (as defined below) prior to the conversion of this note pursuant to
Section 2(a), then the Company shall redeem this Note for an aggregate
consideration substantially equivalent to the consideration which would have
been received by the Holder had the Note been converted into Series B Preferred
Stock immediately prior to the consummation of such Liquidity Event, as
determined in the reasonable and good faith judgement of the Board of Directors
of the Company. For the Purposes of hereof "Liquidity Event" shall mean (i) any
consolidation or merger of the Company with or into any other corporation or
other entity or person, or any other corporate reorganization, in which the
stockholders of the Company immediately prior to such consolidation, merger or
reorganization, own less than 50% of the Company's voting power immediately
after such consolidation, merger or reorganization, or any transaction or series
of related transactions to which the Company is a party in which in excess of
50% of the Company's voting power is transferred (ii) any voluntary or
involuntary liquidation or dissolution of the Company, or (iii) the sale of all
or substantially all the assets of the Company.

          (c)  Mechanics and Effect of Conversion. No fractional shares of the
Company's capital stock will be issued upon conversion of this Note. In lieu of
any fractional share to which the Holder would otherwise be entitled, the
Company will pay to the Holder in cash the amount of the unconverted principal
and interest balance of this Note that would otherwise be converted into such
fractional share. Upon conversion of this Note pursuant to this Section 2, the
Holder shall surrender this Note, duly endorsed, at the principal offices of the
Company or any transfer agent of the Company. At its expense, the Company will,
as soon as practicable thereafter, issue and deliver to such Holder, at such
principal office, a certificate or certificates for the number of shares to
which such Holder is entitled upon such conversion, together with any other
securities and property to which the Holder is entitled upon such conversion
under the terms of this Note, including a check payable to the Holder for any
cash amounts payable as described herein. Upon conversion of this Note, the
Company will be forever released from all of its obligations and liabilities
under this Note with regard to that portion of the principal amount and accrued
interest being converted including without limitation the obligation to pay such
portion of the principal amount and accrued interest.

     3.   Payment.  All payments shall be made in lawful money of the United
States of America at such place as the Holder hereof may from time to time
designate in writing to the Company. Payment shall be credited first to the
accrued interest then due and payable and the remainder applied to principal.
Prepayment of this Note may be made without penalty, if the

                                       2.
<PAGE>

Company's Board of Directors has determined, in consultation with legal counsel,
and with the consent of the Holders of a majority of the outstanding principal
amount of the Notes, that the required clearances or pre-termination notices
under the HSR Act specified in Section 2(a) are not likely to be obtained,
otherwise this note made not prepaid without the consent of the Holders of a
majority of the outstanding principal amount of the Notes; provided, however,
that the Company may repay the Note on or after November 30, 1999 in the event
the conditions to conversion set forth in Section 2 hereof have not occurred.

     4.   Transfer; Successors and Assigns. The terms and conditions of this
Note shall inure to the benefit of and be binding upon the respective successors
and assigns of the parties. Notwithstanding the foregoing, the Company may not
assign, pledge or otherwise transfer this Note without the prior written consent
of the Holder, which shall not be unreasonably withheld, and the Holder may not
assign, pledge, or otherwise transfer this Note without the prior written
consent of the Company, which shall not be unreasonably withheld. Subject to the
preceding sentence, this Note may be transferred only upon surrender of the
original Note for registration of transfer, duly endorsed, or accompanied by a
duly executed written instrument of transfer in form satisfactory to the Holder.
Thereupon, a new note for the same principal amount and interest will be issued
to, and registered in the name of, the transferee. Interest and principal are
payable only to the registered holder of this Note.

     5.   Governing Law. This Note and all acts and transactions pursuant hereto
and the rights and obligations of the parties hereto shall be governed,
construed and interpreted in accordance with the laws of the State of
Washington, without giving effect to principles of conflicts of law.

     6.   Notices. Any notice required or permitted by this Note shall be in
writing and shall be deemed sufficient upon delivery, when delivered personally
or one business day after being sent by a nationally-recognized overnight
delivery service (such as Federal Express or UPS), or forty-eight (48) hours
after being deposited in the U.S. mail, as certified or registered mail, with
postage prepaid, addressed to the party to be notified at such party's address
as set forth below or as subsequently modified by written notice.

     7.   Amendments and Waivers. Any term of this Note may be amended only with
the written consent of the Company and at least a majority in interest of the
Holders. Any amendment or waiver effected in accordance with this Section 7
shall be binding upon the Company, the Holders and each transferee of the Notes.

     8.   Waiver. The Company waives presentment and demand for payment, notice
of dishonor, protest and notice of protest of this Note, and shall pay all costs
of collection when incurred, including, without limitation, reasonable
attorneys' fees, costs and other expenses.

     The right to plead any and all statutes of limitations as a defense to any
demands hereunder is hereby waived to the full extent permitted by law.

<PAGE>

copyrights, trade secrets, licenses, information and other proprietary rights
and processes necessary for its business as now conducted and as presently
proposed to be conducted, without any known infringement of the rights of
others. There are no outstanding options, licenses or agreements of any kind
relating to the foregoing, nor is the Company bound by or a party to any
options, licenses or agreements of any kind with respect to the patents,
trademarks, service marks, trade names, copyrights, trade secrets, licenses,
information and other proprietary rights and processes of any other person or
entity other than such licenses or agreements arising from the purchase of "off
the shelf" or standard products. The Company has not received any communications
alleging that the Company has violated or, by conducting its business as
presently proposed, would violate any of the patents, trademarks, service marks,
trade names, copyrights or trade secrets or other proprietary rights of any
other person or entity. The Company is not aware that any of its employees is
obligated under any contract (including licenses, covenants or commitments of
any nature) or other agreement, or subject to any judgment, decree or order of
any court or administrative agency, that would interfere with their duties to
the Company or that would conflict with the Company's business as presently
proposed to be conducted. Neither the execution nor delivery of this Agreement
or the Related Agreements, nor the carrying on of the Company's business by the
employees of the Company, nor the conduct of the Company's business as presently
proposed, will, to the Company's knowledge, conflict with or result in a breach
of the terms, conditions or provisions of, or constitute a default under, any
contract, covenant or instrument under which any employee is now obligated. The
Company does not believe it is or will be necessary to utilize any inventions,
trade secrets or proprietary information of any of its employees made prior to
their employment by the Company, except for inventions, trade secrets or
proprietary information that have been assigned to the Company.

          3.12  Compliance with Other Instruments. The Company is not in
violation or default of any term of its Restated Charter or Bylaws, or, to the
Company's knowledge, of any provision of any mortgage, indenture, contract,
agreement, instrument or contract to which it is party or by which it is bound
or of any judgment, decree, order, or writ. The execution, delivery, and
performance of and compliance with this Agreement, the Notes and the Related
Agreements, and the issuance and sale of the Shares pursuant hereto and of the
Conversion Shares and the Notes pursuant to the Notes and Restated Charter, will
not, with or without the passage of time or giving of notice, result in any such
material violation, or be in conflict with or constitute a default under any
such term, or result in the creation of any mortgage, pledge, lien, encumbrance
or charge upon any of the properties or assets of the Company or the suspension,
revocation, impairment, forfeiture or non-renewal of any permit, license,
authorization or approval applicable to the Company, its business or operations
or any of its assets or properties.

          3.13  Litigation. There is no action, suit, proceeding or
investigation pending or to the Company's knowledge currently threatened in
writing against the Company that questions the validity of this Agreement, the
Notes or the Related Agreements or the right of the Company to enter into any of
such agreements, or to consummate the transactions contemplated hereby or
thereby, or which might result, either individually or in the aggregate, in any
material adverse change in the assets, condition, affairs or prospects of the
Company, financially or otherwise, or any change in the current equity ownership
of the Company, nor is the Company aware that there is any basis for any of the
foregoing. The foregoing includes, without limitation, actions pending or
threatened in writing (or any basis therefor known to the Company) involving the
prior

                                      7.
<PAGE>

employment of any of the Company's employees, their use in connection with the
Company's business of any information or techniques allegedly proprietary to any
of their former employers, or their obligations under any agreements with prior
employers. The Company is not a party or subject to the provisions of any order,
writ, injunction, judgment or decree of any court or government agency or
instrumentality. There is no action, suit, proceeding or investigation by the
Company currently pending or which the Company intends to initiate.

          3.14  Tax Returns and Payments. The Company has filed all tax returns
(federal, state and local) required to be filed by it.  All taxes shown to be
due and payable on such returns, any assessments imposed, and all other taxes
due and payable by the Company on or before the Closing, have been paid or will
be paid prior to the time they become delinquent.  The Company has not been
advised (a) that any of its returns, federal, state or other, have been or are
being audited as of the date hereof, or (b) of any deficiency in assessment or
proposed judgment to its federal, state or other taxes.  The Company has no
knowledge of any liability for any tax to be imposed upon its properties or
assets as of the date of this Agreement that is not adequately provided for.

          3.15  Employees. The Company has no collective bargaining agreements
with any of its employees.  There is no labor union organizing activity pending
or, to the Company's knowledge, threatened with respect to the Company.  To the
Company's knowledge, no employee of the Company, nor any consultant with whom
the Company has contracted, is in violation of any term of any employment
contract, proprietary information agreement or any other agreement relating to
the right of any such individual to be employed by, or to contract with, the
Company because of the nature of the business to be conducted by the Company;
and to the Company's knowledge the continued employment by the Company of its
present employees, and the performance of the Company's contracts with its
independent contractors, will not result in any such violation.  The Company has
not received any notice alleging that any such violation has occurred.  No
employee of the Company has been granted the right to continued employment by
the Company or to any material compensation following termination of employment
with the Company.  The Company is not aware that any officer or key employee, or
that any group of key employees, intends to terminate his, her or their
employment with the Company, nor does the Company have a present intention to
terminate the employment of any officer, key employee or group of key employees.

          3.16  Proprietary Information and Inventions Agreements. Each
employee, officer and consultant of the Company has executed a Proprietary
Information and Inventions Agreement in the form of Exhibit G attached hereto.
No current employee, officer or consultant of the Company has excluded works or
inventions made prior to his or her employment with the Company from his or her
assignment of inventions pursuant to such employee, officer or consultant's
Proprietary Information and Inventions Agreement.

          3.17  Registration Rights and Voting Rights.

                (a)  Except as required pursuant to the Investor Rights
Agreement, the Company is presently not under any obligation, and has not
granted any rights, to register (as

                                      8.
<PAGE>

defined in Section 1.1 of the Investor Rights Agreement) any of the Company's
presently outstanding securities or any of its securities that may hereafter be
issued.

                 (b)  Except as provided for in the Voting Agreement, to the
Company's knowledge, no shareholder of the Company has entered into any
agreement with respect to the voting of equity securities of the Company.

          3.18   Compliance with Laws; Permits. To its knowledge, the Company is
not in violation of any applicable statute, rule, regulation, order or
restriction of any domestic or foreign government or any instrumentality or
agency thereof in respect of the conduct of its business or the ownership of its
properties which violation would materially and adversely affect the business,
assets, liabilities, financial condition, operations or prospects of the
Company. No governmental orders, permissions, consents, approvals or
authorizations are required to be obtained and no registrations or declarations
are required to be filed in connection with the execution and delivery of this
Agreement and the issuance of the Shares, the Notes or the Conversion Shares,
except such as has been duly and validly obtained or filed, or with respect to
any filings that must be made after the Closing, as will be filed in a timely
manner. The Company has all franchises, permits, licenses and any similar
authority necessary for the conduct of its business as now being conducted by
it, the lack of which could materially and adversely affect the business,
properties, prospects or financial condition of the Company and believes it can
obtain, without undue burden or expense, any similar authority for the conduct
of its business as planned to be conducted.

          3.19   Offering Valid. Assuming the accuracy of the representations
and warranties of the Purchasers contained in Section 4.2 hereof, the offer,
sale and issuance of the Shares, the Notes and the Conversion Shares will be
exempt from the registration requirements of the Securities Act of 1933, as
amended (the "Securities Act"), and will have been registered or qualified (or
are exempt from registration and qualification) under the registration, permit
or qualification requirements of all applicable state securities laws. Neither
the Company nor any agent on its behalf has solicited or will solicit any offers
to sell or has offered to sell or will offer to sell all or any part of the
Shares or the Notes to any person or persons so as to bring the sale of such
Shares by the Company within the registration provisions of the Securities Act
or any state securities laws.

all information requested by the Purchasers in connection with their decision to
purchase the Shares and/or the Notes, including all information the Company
believes is reasonably necessary to make such investment decision. To the
Company's knowledge, neither this Agreement, the Exhibits hereto, the Related
Agreements nor any other document delivered by the Company to Purchasers or
their attorneys or agents in connection herewith or therewith or with the
transactions contemplated hereby or thereby, contain any untrue statement of a
material fact nor, to the Company's knowledge, omit to state a material fact
necessary in order to make the statements contained herein or therein not
misleading.

     4.   Representations And Warranties Of The Purchasers.

          Each Purchaser hereby represents and warrants to the Company as
follows (such representations and warranties do not lessen or obviate the
representations and warranties of the Company set forth in this Agreement):

          4.1  Requisite Power and Authority. Purchaser has all necessary power
and authority under all applicable provisions of law to execute and deliver this
Agreement, the Notes (if applicable) and the Related Agreements and to carry out
their provisions.  All action on Purchaser's part required for the lawful
execution and delivery of this Agreement, the Notes (if applicable) and the
Related Agreements have been or will be effectively taken prior to the Closing.
Upon their execution and delivery, this Agreement, the Notes (if applicable) and
the Related Agreements will be valid and binding obligations of Purchaser,
enforceable in accordance with their terms, except (a) as limited by applicable
bankruptcy, insolvency, reorganization, moratorium or other laws of general
application affecting enforcement of creditors' rights, (b) general principles
of equity that restrict the availability of equitable remedies, and (c) to the
extent that the enforceability of the indemnification provisions of Section 2.9
of the Investor Rights Agreement may be limited by applicable laws.

          4.2  Investment Representations. Purchaser understands that neither
the Shares, the Notes nor the Conversion Shares have been registered under the
Securities Act.  Purchaser also understands that the Shares and the Notes are
being offered and sold pursuant to an exemption from registration contained in
the Securities Act based in part upon Purchaser's representations contained in
this Agreement.  Purchaser hereby represents and warrants as follows:

               (a)  Purchaser Bears Economic Risk. Purchaser has substantial
experience in evaluating and investing in private placement transactions of
securities in companies similar to the Company so that it is capable of
evaluating the merits and risks of its investment in the Company and has the
capacity to protect its own interests. Purchaser must bear the economic risk of
this investment indefinitely unless the Shares (or the Notes or the Conversion
Shares) are registered pursuant to the Securities Act, or an exemption from
registration is available. Purchaser understands that the Company has no present
intention of registering the Shares, the Notes, the Conversion Shares or any
shares of its Common Stock. Purchaser also understands that there is no
assurance that any exemption from registration under the Securities Act will be
available and that, even if available, such exemption may not allow Purchaser to
transfer all or any portion of the Shares, the Notes or the Conversion Shares
under the circumstances, in the amounts or at the times Purchaser might propose.

               (b)  Acquisition for Own Account. Purchaser is acquiring the
Shares, the Notes (if applicable) and the Conversion Shares for Purchaser's own
account for investment only, and not with a view towards their distribution.

               (c)  Purchaser Can Protect Its Interest. Purchaser represents
that by reason of its, or of its management's, business or financial experience,
Purchaser has the capacity to protect its own interests in connection with the
transactions contemplated in this Agreement,

                                      10.
<PAGE>

and the Related Agreements. Further, Purchaser is aware of no publication of any
advertisement in connection with the transactions contemplated in the Agreement.

               (d)  Accredited Investor. Purchaser represents that it is an
accredited investor within the meaning of Regulation D under the Securities Act.

               (e)  Company Information. Purchaser has received and read the
Financial Statements and has had an opportunity to discuss the Company's
business, management and financial affairs with directors, officers and
management of the Company and has had the opportunity to review the Company's
operations and facilities. Purchaser has also had the opportunity to ask
questions of and receive answers from, the Company and its management regarding
the terms and conditions of this investment.

               (f)  Rule 144. Purchaser acknowledges and agrees that the Shares,
the Notes and, if issued, the Conversion Shares must be held indefinitely unless
they are subsequently registered under the Securities Act or an exemption from
such registration is available. Purchaser has been advised or is aware of the
provisions of Rule 144 promulgated under the Securities Act as in effect from
time to time, which permits limited resale of shares purchased in a private
placement subject to the satisfaction of certain conditions, including, among
other things: the availability of certain current public information about the
Company, the resale occurring following the required holding period under Rule
144 and the number of shares being sold during any three-month period not
exceeding specified limitations.

               (g)  Residence. If the Purchaser is an individual, then the
Purchaser resides in the state or province identified in the address of the
Purchaser set forth on Exhibit A; if the Purchaser is a partnership,
corporation, limited liability company or other entity, then the office or
offices of the Purchaser in which its investment decision was made is located at
the address or addresses of the Purchaser set forth on Exhibit A.

          4.3  Transfer Restrictions. Each Purchaser acknowledges and agrees
that the Shares and, if issued, the Conversion Shares are subject to
restrictions on transfer as set forth in the Investor Rights Agreement.

     5.   Conditions To Closing.

Shares have been converted that have not been sold to the public).

               (b)  The obligations of the Company and the rights of the holders
of the Shares and the Conversion Shares under the Agreement may be waived only

          6.8   Waiver of Conflicts. Each party to this Agreement acknowledges
that Cooley Godward LLP ("Cooley Godward"), outside general counsel to the
Company, has in the past performed and is or may now or in the future represent
one or more of the Purchasers or their affiliates in matters unrelated to the
transactions contemplated by this Agreement (the "Financing"), including
representation of such Purchasers or their affiliates in matters of a similar
nature to the Financing. The applicable rules of professional conduct require
that Cooley Godward inform the parties hereunder of this representation and
obtain their consent. Cooley Godward has served as outside general counsel to
the Company and has negotiated the terms of the Financing solely on behalf of
the Company. It is the belief of Cooley Godward that these terms and conditions
represent an arm's length transaction between the Company and the Purchasers.
Purchasers have been represented by independent legal counsel regarding the
terms of the Financing. The Company and each Purchaser hereby (a) acknowledge
that they have had an opportunity to ask for and have obtained information
relevant to such representation, including disclosure of the reasonably
foreseeable adverse consequences of such representation; (b) acknowledge that
with respect to the Financing, Cooley Godward has represented solely the
Company, and not any Purchaser or any stockholder, director or employee of the
Company or any Purchaser; and (c) gives its informed consent to Cooley Godward's
representation the Company in the Financing.

          6.9   Notices. All notices required or permitted hereunder shall be in
writing and shall be deemed effectively given: (a) upon personal delivery to the
party to be notified, (b) when sent by confirmed telex or facsimile if sent
during normal business hours of the recipient, if not, then on the next business
day, (c) five (5) days after having been sent by registered or certified mail,
return receipt requested, postage prepaid, or (d) one (1) day after deposit with
a nationally recognized overnight courier, specifying next day delivery, with
written verification of receipt.  All communications shall be sent to the
Company at the address as set forth on the signature page hereof and to
Purchaser at the address set forth on Exhibit A attached hereto or at such other
address as the Company or Purchaser may designate by ten (10) days advance
written notice to the other parties hereto.

          6.10  Expenses.  The Company shall pay all costs and expenses that it
incurs with respect to the negotiation, execution, delivery and performance of
the Agreement.  The Company shall, at the Closing, reimburse the reasonable fees
of and expenses of one special counsel for the Purchasers, not to exceed
$15,000, incurred in connection with the negotiation, execution, delivery and
performance of this Agreement.

          6.11  Attorneys' Fees. In the event that any suit or action is
instituted to enforce any provision in this Agreement, the prevailing party in
such dispute shall be entitled to recover from the losing party all fees, costs
and expenses of enforcing any right of such prevailing party under or with
respect to this Agreement, including without limitation, such reasonable fees
and expenses of attorneys and accountants, which shall include, without
limitation, all fees, costs and expenses of appeals.

          6.12  Titles and Subtitles. The titles of the sections and subsections
of the Agreement are for convenience of reference only and are not to be
considered in construing this Agreement.

     6.13      Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be an original, but all of which together
shall constitute one instrument.

     6.14      Broker's Fees. Each party hereto represents and warrants that no
agent, broker, investment banker, person or firm acting on behalf of or under
the authority of such party hereto is or will be entitled to any broker's or
finder's fee or any other commission directly or indirectly in connection with
the transactions contemplated herein.  Each party hereto further agrees to
indemnify each other party for any claims, losses or expenses incurred by such
other party as a result of the representation in this Section 6.14 being untrue.

     6.15      Exculpation Among Purchasers. Each Purchaser acknowledges that it
is not relying upon any person, firm, or corporation, other than the Company and
its officers and directors, in making its investment or decision to invest in
the Company.  Each Purchaser agrees that no Purchaser nor the respective
controlling persons, officers, directors, partners, agents, or employees of any
Purchaser shall be liable to any other Purchaser for any action heretofore or
hereafter taken or omitted to be taken by any of them in connection with the
Shares and Conversion Shares.

     6.16      Confidentiality. Each party hereto agrees that, except with the
prior written consent of the other party, it shall at all times keep
confidential and not divulge, furnish or make accessible to anyone any
confidential information, knowledge or data concerning or relating to the
business or financial affairs of the other parties to which such party has been
or shall become privy by reason of this Agreement or the Related Agreements,
discussions or negotiations relating to this Agreement or the Related
Agreements, the performance of its obligations hereunder or the ownership of the
Shares purchased hereunder.  The provisions of this Section 6.16 shall be in
addition to, and not in substitution for, the provisions of any separate
nondisclosure agreement executed by the parties hereto.

     6.17      Pronouns. All pronouns contained herein, and any variations
thereof, shall be deemed to refer to the masculine, feminine or neutral,
singular or plural, as to the identity of the parties hereto may require.

     6.18      California Corporate Securities Law. THE SALE OF THE SECURITIES
WHICH ARE THE SUBJECT OF THIS AGREEMENT HAS NOT BEEN QUALIFIED WITH THE
COMMISSIONER OF CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF SUCH
SECURITIES OR THE PAYMENT OR RECEIPT OF ANY PART OF THE CONSIDERATION THEREFOR
PRIOR TO SUCH QUALIFICATION OR IN THE ABSENCE OF AN EXEMPTION FROM SUCH
QUALIFICATION IS UNLAWFUL.  PRIOR TO ACCEPTANCE OF SUCH CONSIDERATION BY THE
COMPANY, THE RIGHTS OF ALL PARTIES TO THIS AGREEMENT ARE EXPRESSLY CONDITIONED
UPON SUCH QUALIFICATION BEING OBTAINED OR AN EXEMPTION FROM SUCH QUALIFICATION
BEING AVAILABLE.

$9,999,999.89                                                      March 1, 2000
                                                            Bellevue, Washington

     For value received, Mercata, Inc., a Delaware corporation (the "Company"),
promises to pay to Waelinvest. (the "Holder"), the principal sum of nine million
nine hundred ninety-nine thousand nine hundred ninety-nine dollars and eighty-
nine cents ($9,999,999.89). No interest shall accrue or be paid on this Note;
provided, that if this Note shall not have converted in accordance with Section
2 below on or before May 31, 2000, this Note shall bear interest accruing from
the date hereof on the unpaid principal amount at a rate equal to the lower of
(a) 7.00% per annum, compounded annually or (b) the highest rate permitted by
law. This Note is one of a series of Convertible Promissory Notes containing
substantially identical terms and conditions issued pursuant to that certain
Series C Preferred Stock Purchase Agreement, dated March 1, 2000 (the "Purchase
Agreement"). Such Notes are referred to herein as the "Notes," and the holders
thereof are referred to herein as the "Holders." This Note is subject to the
following terms and conditions.

     1.   Maturity.  Unless converted as provided in Section 2, this Note will
automatically mature and be due and payable on May 31, 2000 (the "Maturity
Date"). Subject to Section 2 below, any interest shall accrue on this Note but
shall not be due and payable until the Maturity Date.

     2.   Conversion

          (a)  HSR Clearance.  As soon as practicable after the Closing (as
defined in the Purchase Agreement), the Company and the Holder hereby agree to
file or to cause to be filed with the United States Federal Trade Commission
(the "FTC") and the Antitrust Division of the United States Department of
Justice (the "DOJ") pursuant to the Hart-Scott-Rodino Antitrust Improvements Act
of 1976, as amended (the "HSR Act") all requisite documents and notifications in
order to provide for the conversion of this Note into shares of the Company's
Series C Preferred Stock. Upon the earlier of one business day after (i) the
date all required clearances or pre-termination notices under the HSR Act have
been received from the FTC and the DOJ (or all applicable waiting periods have
expired) or (ii) the date the Holder and the Company are no longer required by
law to make filings under the HSR to convert this Note into capital stock, the
entire principal amount of this Note shall automatically convert into fully-paid
and non-assessable shares of the Company's Series C Preferred Stock (the
"Stock"); provided,

                                       1.
<PAGE>

however, the automatic conversion of such principal amount into shares of the
Stock shall be conditioned upon (A) the Company having provided to the Holder a
compliance certificate in the form attached hereto as Exhibit A or (B) the
Holder having waived such applicable terms, conditions or certifications
included in such certificate, either individually or in the aggregate. The
number of shares of Stock to be issued upon such conversion shall be equal to
the quotient obtained by dividing (i) the entire outstanding principal amount of
this Note by (ii) $11.894142 (as adjusted for any future stock splits, stock
dividends, recapitalizations or the like to the Stock), provided that no
fractional shares shall be issued. In the event that the required clearances
from the FTC and the DOJ are not obtained, this Note shall not be convertible
into the Stock.

          (b)  Redemption. In the event the Company consummates a Liquidity
Event (as defined below) prior to the conversion of this note pursuant to
Section 2(a), then the Company shall redeem this Note for an aggregate
consideration substantially equivalent to the consideration which would have
been received by the Holder had the Note been converted into Series C Preferred
Stock immediately prior to the consummation of such Liquidity Event, as
determined in the reasonable and good faith judgement of the Board of Directors
of the Company. For the Purposes of hereof "Liquidity Event" shall mean (i) any
consolidation or merger of the Company with or into any other corporation or
other entity or person, or any other corporate reorganization, in which the
stockholders of the Company immediately prior to such consolidation, merger or
reorganization, own less than 50% of the Company's voting power immediately
after such consolidation, merger or reorganization, or any transaction or series
of related transactions to which the Company is a party in which in excess of
50% of the Company's voting power is transferred (ii) any voluntary or
involuntary liquidation or dissolution of the Company, or (iii) the sale of all
or substantially all the assets of the Company.

          (c)  Mechanics and Effect of Conversion. No fractional shares of the
Company's capital stock will be issued upon conversion of this Note. In lieu of
any fractional share to which the Holder would otherwise be entitled, the
Company will pay to the Holder in cash the amount of the unconverted principal
and interest balance of this Note that would otherwise be converted into such
fractional share. Upon conversion of this Note pursuant to this Section 2, the
Holder shall surrender this Note, duly endorsed, at the principal offices of the
Company or any transfer agent of the Company. At its expense, the Company will,
as soon as practicable thereafter, issue and deliver to such Holder, at such
principal office, a certificate or certificates for the number of shares to
which such Holder is entitled upon such conversion, together with any other
securities and property to which the Holder is entitled upon such conversion
under the terms of this Note, including a check payable to the Holder for any
cash amounts payable as described herein. Upon conversion of this Note, the
Company will be forever released from all of its obligations and liabilities
under this Note with regard to that portion of the principal amount and accrued
interest being converted including without limitation the obligation to pay such
portion of the principal amount and accrued interest.

     3.   Payment.  All payments shall be made in lawful money of the United
States of America at such place as the Holder hereof may from time to time
designate in writing to the Company. Payment shall be credited first to the
accrued interest then due and payable and the remainder applied to principal.
Prepayment of this Note may be made without penalty, if the Company's Board of
Directors has determined, in consultation with legal counsel, and with the

                                       2.
<PAGE>

consent of the Holders of a majority of the outstanding principal amount of the
Notes, that the required clearances or pre-termination notices under the HSR Act
specified in Section 2(a) are not likely to be obtained, otherwise this note
made not prepaid without the consent of the Holders of a majority of the
outstanding principal amount of the Notes; provided, however, that the Company
may repay the Note on or after May 31, 2000 in the event the conditions to
conversion set forth in Section 2 hereof have not occurred.

     4.   Transfer; Successors and Assigns.  The terms and conditions of this
Note shall inure to the benefit of and be binding upon the respective successors
and assigns of the parties. Notwithstanding the foregoing, the Company may not
assign, pledge or otherwise transfer this Note without the prior written consent
of the Holder, which shall not be unreasonably withheld, and the Holder may not
assign, pledge, or otherwise transfer this Note without the prior written
consent of the Company, which shall not be unreasonably withheld. Subject to the
preceding sentence, this Note may be transferred only upon surrender of the
original Note for registration of transfer, duly endorsed, or accompanied by a
duly executed written instrument of transfer in form satisfactory to the Holder.
Thereupon, a new note for the same principal amount and interest will be issued
to, and registered in the name of, the transferee. Interest and principal are
payable only to the registered holder of this Note.

     5.   Governing Law. This Note and all acts and transactions pursuant hereto
and the rights and obligations of the parties hereto shall be governed,
construed and interpreted in accordance with the laws of the State of
Washington, without giving effect to principles of conflicts of law.

     6.   Notices.  Any notice required or permitted by this Note shall be in
writing and shall be deemed sufficient upon delivery, when delivered personally
or one business day after being sent by a nationally-recognized overnight
delivery service (such as Federal Express or UPS), or forty-eight (48) hours
after being deposited in the U.S. mail, as certified or registered mail, with
postage prepaid, addressed to the party to be notified at such party's address
as set forth below or as subsequently modified by written notice.

     7.   Amendments and Waivers.  Any term of this Note may be amended only
with the written consent of the Company and at least a majority in interest of
the Holders. Any amendment or waiver effected in accordance with this Section 7
shall be binding upon the Company, the Holders and each transferee of the Notes.

     8.   Waiver.  The Company waives presentment and demand for payment, notice
of dishonor, protest and notice of protest of this Note, and shall pay all costs
of collection when incurred, including, without limitation, reasonable
attorneys' fees, costs and other expenses.

     The right to plead any and all statutes of limitations as a defense to any
demands hereunder is hereby waived to the full extent permitted by law.

Securities Act covering such proposed disposition and such disposition is made
in accordance with such registration statement; or

              (ii)   (A) The transferee has agreed in writing to be bound by the
terms of this Agreement, (B) such Holder shall have notified the Company of the
proposed disposition and shall have furnished the Company with a detailed
statement of the circumstances surrounding the proposed disposition, and (C) if
reasonably requested by the Company, such Holder shall have furnished the
Company with an opinion of counsel, reasonably satisfactory to the Company, that
such disposition will not require registration of such shares under the
Securities Act. It is agreed that the Company will not require opinions of
counsel for transactions made pursuant to Rule 144 except in unusual
circumstances.

              (iii)  Notwithstanding the provisions of paragraphs (i) and (ii)
above, no such registration statement or opinion of counsel shall be necessary
for a transfer by a Holder which is (A) a partnership to its partners or former
partners in accordance with partnership interests, (B) a corporation to its
shareholders in accordance with their interest in the corporation, (C) a limited
liability company to its members or former members in accordance with their
interest in the limited liability company, or (D) to the Holder's family member
or trust for the benefit of an individual Holder; provided that in each case the
transferee will be subject to the terms of this Agreement to the same extent as
if he were an original Holder hereunder.

          (b) Each certificate representing Shares or Registrable Securities
shall (unless otherwise permitted by the provisions of the Agreement) be stamped
or otherwise imprinted with a legend substantially similar to the following (in
addition to any legend required under applicable state securities laws):

     THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
     THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED,
     SOLD OR OTHERWISE

                                      3.
<PAGE>

       TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS AND
       UNTIL REGISTERED UNDER THE ACT OR UNLESS THE COMPANY HAS
       RECEIVED AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY
       AND ITS COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED.

       (c) The Company shall be obligated to reissue promptly unlegended
certificates at the request of any holder thereof if the holder shall have
obtained an opinion of counsel (which counsel may be counsel to the Company)
reasonably acceptable to the Company to the effect that the securities proposed
to be disposed of may lawfully be so disposed of without registration,
qualification or legend.

       (d) Any legend endorsed on an instrument pursuant to applicable state
securities laws and the stop-transfer instructions with respect to such
securities shall be removed upon receipt by the Company of an order of the
appropriate blue sky authority authorizing such removal.

  2.2  Demand Registration.

       (a) Subject to the conditions of this Section 2.2, if the Company shall
receive a written request from the Holders (the "Initiating Holders") proposing
to sell Registrable Securities at an anticipated aggregate offering price, net
of underwriting discounts and commissions, exceeding twenty-five million dollars
($25,000,000) (a "Qualified Public Offering")), then the Company shall, within
thirty (30) days of the receipt thereof, give written notice of such request to
all Holders, and subject to the limitations of this Section 2.2, use its best
efforts to effect, as soon as practicable, the registration under the Securities
Act of all Registrable Securities that the Holders request to be registered.

       (b) If the Initiating Holders intend to distribute the Registrable
Securities covered by their request by means of an underwriting, they shall so
advise the Company as a part of their request made pursuant to this Section 2.2
or any request pursuant to Section 2.4 and the Company shall include such
information in the written notice referred to in Section 2.2(a) or Section
2.4(a), as applicable.  In such event, the right of any Holder to include its
Registrable Securities in such registration shall be conditioned upon such
Holder's participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting to the extent provided herein.  All
Holders proposing to distribute their securities through such underwriting shall
enter into an underwriting agreement in customary form with the underwriter or
underwriters selected for such underwriting by a majority in interest of the
Initiating Holders (which underwriter or underwriters shall be reasonably
acceptable to the Company).  Notwithstanding any other provision of this Section
2.2 or Section 2.4, if the underwriter advises the Company that marketing
factors require a limitation of the number of securities to be underwritten
(including Registrable Securities) then the Company shall so advise all Holders
of Registrable Securities which would otherwise be underwritten pursuant hereto,
and the number of shares that may be included in the underwriting shall be
allocated to the Holders of such Registrable Securities on a pro rata basis
based on the number of Registrable Securities held by all such Holders
(including the Initiating Holders); provided, however, that the number of shares
of Registrable Securities to be included in such underwriting and registration
shall not be

                                      4.
<PAGE>

reduced unless all other securities of the Company are first entirely excluded
from the underwriting and registration. Any Registrable Securities excluded or
withdrawn from such underwriting shall be withdrawn from the registration.

        (c) The Company shall not be required to effect a registration pursuant
to this Section 2.2:

            (i)    prior to one hundred eighty (180) days following the
effective date of the registration statement pertaining to the Initial Offering;

            (ii)   after the Company has effected two (2) registrations pursuant
to this Section 2.2, and such registrations have been declared or ordered
effective;

            (iii)  if the Company shall furnish to Holders requesting a
registration statement pursuant to this Section 2.2, a certificate signed by the
Chairman of the Board stating that in the good faith judgment of the Board of
Directors of the Company, it would be seriously detrimental to the Company and
its shareholders for such registration statement to be effected at such time, in
which event the Company shall have the right to defer such filing for a period
of not more than ninety (90) days after receipt of the request of the Initiating
Holders; provided that such right to delay a request shall be exercised by the
Company not more than once in any twelve (12) month period; or

            (iv)   if the Initiating Holders propose to dispose of shares of
Registrable Securities that may be immediately registered on Form S-3 pursuant
to a request made pursuant to Section 2.4 below.

  2.3     Piggyback Registrations.  The Company shall notify all Holders of
Registrable Securities in writing at least fifteen (15) days prior to the filing
of any registration statement under the Securities Act for purposes of a public
offering of securities of the Company (including, but not limited to,
registration statements relating to secondary offerings of securities of the
Company, but excluding registration statements relating to employee benefit
plans or with respect to corporate reorganizations or other transactions under
Rule 145 of the Securities Act) and will afford each such Holder an opportunity
to include in such registration statement all or part of such Registrable
Securities held by such Holder.  Each Holder desiring to include in any such
registration statement all or any part of the Registrable Securities held by it
shall, within ten (10) days after the above-described notice from the Company,
so notify the Company in writing.  Such notice shall state the intended method
of disposition of the Registrable Securities by such Holder.  If a Holder
decides not to include all of its Registrable Securities in any registration
statement thereafter filed by the Company, such Holder shall nevertheless
continue to have the right to include any Registrable Securities in any
subsequent registration statement or registration statements as may be filed by
the Company with respect to offerings of its securities, all upon the terms and
conditions set forth herein.

          (a) Underwriting. If the registration statement under which the
Company gives notice under this Section 2.3 is for an underwritten offering, the
Company shall so advise the Holders of Registrable Securities. In such event,
the right of any such Holder to be included in a registration pursuant to this
Section 2.3 shall be conditioned upon such Holder's

                                      5.
<PAGE>

participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting to the extent provided herein. All
Holders proposing to distribute their Registrable Securities through such
underwriting shall enter into an underwriting agreement in customary form with
the underwriter or underwriters selected for such underwriting by the Company.
Notwithstanding any other provision of the Agreement, if the underwriter
determines in good faith that marketing factors require a limitation of the
number of shares to be underwritten, the number of shares that may be included
in the underwriting shall be allocated, first, to the Company; second, to the
Holders on a pro rata basis based on the total number of Registrable Securities
held by the Holders; and third, to any shareholder of the Company (other than a
Holder) on a pro rata basis. No such reduction shall (i) reduce the securities
being offered by the Company for its own account to be included in the
registration and underwriting, or (ii) reduce the amount of securities of the
selling Holders included in the registration below twenty-five percent (25%) of
the total amount of securities included in such registration, unless such
offering is the Initial Offering and such registration does not include shares
of any other selling shareholders, in which event any or all of the Registrable
Securities of the Holders may be excluded in accordance with the immediately
preceding sentence. In no event will shares of any other selling shareholder be
included in such registration which would reduce the number of shares which may
be included by Holders without the written consent of Holders of not less than a
majority of the Registrable Securities proposed to be sold in the offering. If
any Holder disapproves of the terms of any such underwriting, such Holder may
elect to withdraw therefrom by written notice to the Company and the
underwriter, delivered at least ten (10) business days prior to the effective
date of the registration statement. Any Registrable Securities excluded or
withdrawn from such underwriting shall be excluded and withdrawn from the
registration. For any Holder which is a partnership or corporation, the
partners, retired partners and shareholders of such Holder, or the estates and
family members of any such partners and retired partners and any trusts for the
benefit of any of the foregoing person shall be deemed to be a single "Holder",
and any pro rata reduction with respect to such "Holder" shall be based upon the
aggregate amount of shares carrying registration rights owned by all entities
and individuals included in such "Holder," as defined in this sentence.

          (b) Right to Terminate Registration. The Company shall have the right
to terminate or withdraw any registration initiated by it under this Section 2.3
prior to the effectiveness of such registration whether or not any Holder has
elected to include securities in such registration. The Registration Expenses of
such withdrawn registration shall be borne by the Company in accordance with
Section 2.5 hereof.

  2.4     Form S-3 Registration.  In case the Company shall receive from any
Holder or Holders of Registrable Securities a written request or requests that
the Company effect a registration on Form S-3 (or any successor to Form S-3) or
any similar short-form registration statement and any related qualification or
compliance with respect to all or a part of the Registrable Securities owned by
such Holder or Holders, the Company will:

          (a) promptly give written notice of the proposed registration, and any
related qualification or compliance, to all other Holders of Registrable
Securities; and

          (b) as soon as practicable, effect such registration and all such
qualifications and compliances as may be so requested and as would permit or
facilitate the sale and

                                      6.
<PAGE>

distribution of all or such portion of such Holder's or Holders' Registrable
Securities as are specified in such request, together with all or such portion
of the Registrable Securities of any other Holder or Holders joining in such
request as are specified in a written request given within fifteen (15) days
after receipt of such written notice from the Company; provided, however, that
the Company shall not be obligated to effect any such registration,
qualification or compliance pursuant to this Section 2.4:

              (i)    if Form S-3 (or any successor or similar form) is not
available for such offering by the Holders, or

              (ii)   if the Holders, together with the holders of any other
securities of the Company entitled to inclusion in such registration, propose to
sell Registrable Securities and such other securities (if any) at an aggregate
price to the public of less than two million dollars ($2,000,000), or

              (iii)  if within thirty (30) days of receipt of a written request
from  any Holder or Holders pursuant to this Section 2.4, the Company gives
notice to such Holder or Holders of the Company's intention to make a public
offering within ninety (90) days;

              (iv)   if the Company shall furnish to the Holders a certificate
signed by the Chairman of the Board of Directors of the Company stating that in
the good faith judgment of the Board of Directors of the Company, it would be
seriously detrimental to the Company and its shareholders for such Form S-3
registration to be effected at such time, in which event the Company shall have
the right to defer the filing of the Form S-3 registration statement for a
period of not more than ninety (90) days after receipt of the request of the
Holder or Holders under this Section 2.4; provided, that such right to delay a
request shall be exercised by the Company not more than once in any twelve (12)
month period, or

              (v)    in any particular jurisdiction in which the Company would
be required to qualify to do business or to execute a general consent to service
of process in effecting such registration, qualification or compliance.

          (c) Subject to the foregoing, the Company shall file a Form S-3
registration statement covering the Registrable Securities and other securities
so requested to be registered as soon as practicable after receipt of the
request or requests of the Holders.  Registrations effected pursuant to this
Section 2.4 shall not be counted as demands for registration or registrations
effected pursuant to Sections 2.2 or 2.3, respectively.

  2.5     Expenses of Registration.  Except as specifically provided herein, all
Registration Expenses incurred in connection with any registration,
qualification or compliance pursuant to Section 2.2 or any registration under
Section 2.3 or Section 2.4 herein shall be borne by the Company.  All Selling
Expenses incurred in connection with any registrations hereunder, shall be borne
by the holders of the securities so registered pro rata on the basis of the
number of shares so registered.  The Company shall not, however, be required to
pay for expenses of any registration proceeding begun pursuant to Section 2.2 or
2.4, the request of which has been subsequently withdrawn by the Initiating
Holders unless (a) the withdrawal is based upon material adverse information
concerning the Company of which the Initiating Holders were not

                                      7.
<PAGE>

aware at the time of such request or (b) the Holders of a majority of
Registrable Securities agree to forfeit their right to one requested
registration pursuant to Section 2.2 or Section 2.4, as applicable, in which
event such right shall be forfeited by all Holders. If the Holders are required
to pay the Registration Expenses, such expenses shall be borne by the holders of
securities (including Registrable Securities) requesting such registration in
proportion to the number of shares for which registration was requested. If the
Company is required to pay the Registration Expenses of a withdrawn offering
pursuant to clause (a) above, then the Holders shall not forfeit their rights
pursuant to Section 2.2 or Section 2.4 to a demand registration.

  2.6     Obligations of the Company.  Whenever required to effect the
registration of any Registrable Securities, the Company shall, as expeditiously
as reasonably possible:

          (a) Prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use all reasonable efforts to cause
such registration statement to become effective, and, upon the request of the
Holders of a majority of the Registrable Securities registered thereunder, keep
such registration statement effective for up to thirty (30) days or, if earlier,
until the Holder or Holders have completed the distribution related thereto. The
Company shall not be required to file, cause to become effective or maintain the
effectiveness of any registration statement that contemplates a distribution of
securities on a delayed or continuous basis pursuant to Rule 415 under the
Securities Act.

          (b) Prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Securities Act with respect to the disposition of all securities covered by such
registration statement for the period set forth in paragraph (a) above.

          (c) Furnish to the Holders such number of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Securities Act, and such other documents as they may reasonably request in order
to facilitate the disposition of Registrable Securities owned by them.

          (d) Use its reasonable best efforts to register and qualify the
securities covered by such registration statement under such other securities or
Blue Sky laws of such jurisdictions as shall be reasonably requested by the
Holders; provided that the Company shall not be required in connection therewith
or as a condition thereto to qualify to do business or to file a general consent
to service of process in any such states or jurisdictions.

          (e) In the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter(s) of such offering.  Each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement.

          (f) Notify each Holder of Registrable Securities covered by such
registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits

                                      8.
<PAGE>

to state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing.

          (g) Use its best efforts to furnish, on the date that such Registrable
Securities are delivered to the underwriters for sale, if such securities are
being sold through underwriters, (i) an opinion, dated as of such date, of the
counsel representing the Company for the purposes of such registration, in form
and substance as is customarily given to underwriters in an underwritten public
offering, addressed to the underwriters, if any, and (ii) a letter dated as of
such date, from the independent certified public accountants of the Company, in
form and substance as is customarily given by independent certified public
accountants to underwriters in an underwritten public offering addressed to the
underwriters.

  2.7     Termination of Registration Rights.  All registration rights granted
under this Section 2 shall terminate and be of no further force and effect three
(3) years after the date of the Company's Initial Offering.  In addition, a
Holder's registration rights shall expire if all Registrable Securities held by
and issuable to such Holder (and its affiliates, partners, former partners,
members and former members) may be sold under Rule 144 during any ninety (90)
day period.

  2.8     Delay of Registration; Furnishing Information.

          (a) No Holder shall have any right to obtain or seek an injunction
restraining or otherwise delaying any such registration as the result of any
controversy that might arise with respect to the interpretation or
implementation of this Section 2.

          (b) It shall be a condition precedent to the obligations of the
Company to take any action pursuant to Section 2.2, 2.3 or 2.4 that the selling
Holders shall furnish to the Company such information regarding themselves, the
Registrable Securities held by them and the intended method of disposition of
such securities as shall be required to effect the registration of their
Registrable Securities.

          (c) The Company shall have no obligation with respect to any
registration requested pursuant to Section 2.2 or Section 2.4 if, due to the
operation of subsection 2.2(b), the number of shares or the anticipated
aggregate offering price of the Registrable Securities to be included in the
registration does not equal or exceed the number of shares or the anticipated
aggregate offering price required to originally trigger the Company's obligation
to initiate such registration as specified in Section 2.2 or Section 2.4,
whichever is applicable.

  2.9     Indemnification.  In the event any Registrable Securities are included
in a registration statement under Sections 2.2, 2.3 or 2.4:

          (a) To the extent permitted by law, the Company will indemnify and
hold harmless each Holder, the partners, officers and directors of each Holder,
any underwriter (as defined in the Securities Act) for such Holder and each
person, if any, who controls such Holder or underwriter within the meaning of
the Securities Act or the Exchange Act, against any losses, claims, damages, or
liabilities (joint or several) to which they may become subject under the
Securities Act, the Exchange Act or other federal or state law, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any of the

                                      9.
<PAGE>

following statements, omissions or violations (collectively a "Violation") by
the Company: (i) any untrue statement or alleged untrue statement of a material
fact contained in such registration statement, including any preliminary
prospectus or final prospectus contained therein or any amendments or
supplements thereto, (ii) the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the statements
therein not misleading, or (iii) any violation or alleged violation by the
Company of the Securities Act, the Exchange Act, any state securities law or any
rule or regulation promulgated under the Securities Act, the Exchange Act or any
state securities law in connection with the offering covered by such
registration statement; and the Company will pay as incurred to each such
Holder, partner, officer, director, underwriter or controlling person for any
legal or other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action;
provided however, that the indemnity agreement contained in this Section 2.9(a)
shall not apply to amounts paid in settlement of any such loss, claim, damage,
liability or action if such settlement is effected without the consent of the
Company, which consent shall not be unreasonably withheld, nor shall the Company
be liable in any such case for any such loss, claim, damage, liability or action
to the extent that it arises out of or is based upon a Violation which occurs in
reliance upon and in conformity with written information furnished expressly for
use in connection with such registration by such Holder, partner, officer,
director, underwriter or controlling person of such Holder.

          (b) To the extent permitted by law, each Holder will, if Registrable
Securities held by such Holder are included in the securities as to which such
registration qualifications or compliance is being effected, indemnify and hold
harmless the Company, each of its directors, its officers and each person, if
any, who controls the Company within the meaning of the Securities Act, any
underwriter and any other Holder selling securities under such registration
statement or any of such other Holder's partners, directors or officers or any
person who controls such Holder, against any losses, claims, damages or
liabilities (joint or several) to which the Company or any such director,
officer, controlling person, underwriter or other such Holder, or partner,
director, officer or controlling person of such other Holder may become subject
under the Securities Act, the Exchange Act or other federal or state law,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereto) arise out of or are based upon any Violation, in each case to the
extent (and only to the extent) that such Violation occurs in reliance upon and
in conformity with written information furnished by such Holder under an
instrument duly executed by such Holder and stated to be specifically for use in
connection with such registration; and each such Holder will pay as incurred any
legal or other expenses reasonably incurred by the Company or any such director,
officer, controlling person, underwriter or other Holder, or partner, officer,
director or controlling person of such other Holder in connection with
investigating or defending any such loss, claim, damage, liability or action if
it is judicially determined that there was such a Violation; provided, however,
that the indemnity agreement contained in this Section 2.9(b) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action
if such settlement is effected without the consent of the Holder, which consent
shall not be unreasonably withheld; provided further, that in no event shall any
indemnity under this Section 2.9 exceed the proceeds from the offering received
by such Holder.

          (c) Promptly after receipt by an indemnified party under this Section
2.9 of notice of the commencement of any action (including any governmental
action), such indemnified party will, if a claim in respect thereof is to be
made against any indemnifying party

                                      10.
<PAGE>

under this Section 2.9, deliver to the indemnifying party a written notice of
the commencement thereof and the indemnifying party shall have the right to
participate in, and, to the extent the indemnifying party so desires, jointly
with any other indemnifying party similarly noticed, to assume the defense
thereof with counsel mutually satisfactory to the parties; provided, however,
that an indemnified party shall have the right to retain its own counsel, with
the fees and expenses to be paid by the indemnifying party, if representation of
such indemnified party by the counsel retained by the indemnifying party would
be inappropriate due to actual or potential differing interests between such
indemnified party and any other party represented by such counsel in such
proceeding. The failure to deliver written notice to the indemnifying party
within a reasonable time of the commencement of any such action, if materially
prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
2.9, but the omission so to deliver written notice to the indemnifying party
will not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 2.9.

          (d) If the indemnification provided for in this Section 2.9 is held by
a court of competent jurisdiction to be unavailable to an indemnified party with
respect to any losses, claims, damages or liabilities referred to herein, the
indemnifying party, in lieu of indemnifying such indemnified party thereunder,
shall to the extent permitted by applicable law contribute to the amount paid or
payable by such indemnified party as a result of such loss, claim, damage or
liability in such proportion as is appropriate to reflect the relative fault of
the indemnifying party on the one hand and of the indemnified party on the other
in connection with the Violation(s) that resulted in such loss, claim, damage or
liability, as well as any other relevant equitable considerations.  The relative
fault of the indemnifying party and of the indemnified party shall be determined
by a court of law by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or the omission to state a material
fact relates to information supplied by the indemnifying party or by the
indemnified party and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission;
provided, that in no event shall any contribution by a Holder hereunder exceed
the proceeds from the offering received by such Holder.

          (e) The obligations of the Company and Holders under this Section 2.9
shall survive completion of any offering of Registrable Securities in a
registration statement and the termination of this agreement. No Indemnifying
Party, in the defense of any such claim or litigation, shall, except with the
consent of each Indemnified Party, consent to entry of any judgment or enter
into any settlement which does not include as an unconditional term thereof the
giving by the claimant or plaintiff to such Indemnified Party of a release from
all liability in respect to such claim or litigation.

  2.10    Assignment of Registration Rights.  The rights to cause the Company to
register Registrable Securities pursuant to this Section 2 may be assigned by a
Holder to a transferee or assignee of Registrable Securities which (a) is an
Affiliate, general partner, limited partner, retired partner, member or retired
member of a Holder, (b) is a Holder's family member or trust for the benefit of
an individual Holder, or (c) acquires at least one hundred thousand (100,000)
shares of Registrable Securities (as adjusted for stock splits and
combinations); provided, however, (i) the transferor shall, within ten (10) days
after such transfer, furnish to the Company written notice of the name and
address of such transferee or assignee and the securities with

                                      11.
<PAGE>

respect to which such registration rights are being assigned and (ii) such
transferee shall agree to be subject to all restrictions set forth in this
Agreement.

  2.11    Amendment of Registration Rights.  Any provision of this Section 2 may
be amended and the observance thereof may be waived (either generally or in a
particular instance and either retroactively or prospectively), only with the
written consent of the Company and the Holders of at least a majority of the
Registrable Securities then outstanding.  Any amendment or waiver effected in
accordance with this Section 2.11 shall be binding upon each Holder and the
Company.  By acceptance of any benefits under this Section 2, Holders of
Registrable Securities hereby agree to be bound by the provisions hereunder.

  2.12    Limitation on Subsequent Registration Rights.  After the date of this
Agreement, the Company shall not, without the prior written consent of the
Holders of a majority of the Registrable Securities then outstanding, enter into
any agreement with any holder or prospective holder of any securities of the
Company that would grant such holder registration rights pari passu or senior to
those granted to the Holders hereunder.

  2.13    "Market Stand-Off" Agreement; Agreement to Furnish Information.  Each
Holder hereby agrees that such Holder shall not sell, transfer, make any short
sale of, grant any option for the purchase of, or enter into any hedging or
similar transaction with the same economic effect as a sale, any Common Stock
(or other securities) of the Company held by such Holder (other than those
included in the registration) for a period specified by the representative of
the underwriters of Common Stock (or other securities) of the Company not to
exceed one hundred eighty (180) days following the effective date of a
registration statement of the Company filed under the Securities Act; provided
that:

          (a) such agreement shall apply only to the Company's Initial Offering;

          (b) all officers and directors of the Company enter into similar
agreements;

          (c) such agreement shall not apply to the purchase or sale of Common
Stock (or other securities registered by the Company) acquired in the Company's
Initial Offering (other than any shares that are purchased in the Initial
Offering as part of a directed share program) or on the open market after the
Company's Initial Offering by Amerindo.

          Each Holder agrees to execute and deliver such other agreements as may
be reasonably requested by the Company or the underwriter which are consistent
with the foregoing or which are necessary to give further effect thereto. In
addition, if requested by the Company or the representative of the underwriters
of Common Stock (or other securities) of the Company, each Holder shall provide,
within ten (10) days of such request, such information as may be required by the
Company or such representative in connection with the completion of any public
offering of the Company's securities pursuant to a registration statement filed
under the Securities Act.  The obligations described in this Section 2.13 shall
not apply to a registration relating solely to employee benefit plans on Form S-
1 or Form S-8 or similar forms that may be promulgated in the future, or a
registration relating solely to a Commission Rule 145 transaction on Form S-4 or
similar forms that may be promulgated in the future.  The Company may impose
stop-transfer instructions with respect to the shares of Common Stock (or other
securities)

                                      12.
<PAGE>

subject to the foregoing restriction until the end of said one hundred eighty
(180) day period.

  2.14      Rule 144 Reporting.  With a view to making available to the Holders
the benefits of certain rules and regulations of the SEC which may permit the
sale of the Registrable Securities to the public without registration, the
Company agrees to use its best efforts to:

            (a) Make and keep public information available, as those terms are
understood and defined in SEC Rule 144 or any similar or analogous rule
promulgated under the Securities Act, at all times after the effective date of
the first registration filed by the Company for an offering of its securities to
the general public;

            (b) File with the SEC, in a timely manner, all reports and other
documents required of the Company under the Exchange Act; and

            (c) So long as a Holder owns any Registrable Securities, furnish to
such Holder forthwith upon request: a written statement by the Company as to its
compliance with the reporting requirements of said Rule 144 of the Securities
Act, and of the Exchange Act (at any time after it has become subject to such
reporting requirements); a copy of the most recent annual or quarterly report of
the Company; and such other reports and documents as a Holder may reasonably
request in availing itself of any rule or regulation of the SEC allowing it to
sell any such securities without registration.

SECTION 3.  COVENANTS OF THE COMPANY

  3.1       Basic Financial Information and Reporting.

            (a) The Company will maintain true books and records of account in
which full and correct entries will be made of all its business transactions
pursuant to a system of accounting established and administered in accordance
with generally accepted accounting principles consistently applied, and will set
aside on its books all such proper accruals and reserves as shall be required
under generally accepted accounting principles consistently applied.

            (b) As soon as practicable after the end of each fiscal year of the
Company, and in any event within one hundred twenty (120) days thereafter, the
Company will furnish to each Investor a balance sheet of the Company, as at the
end of such fiscal year, and a statement of income and a statement of cash flows
of the Company, for such year, all prepared in accordance with generally
accepted accounting principles consistently applied and setting forth in each
case in comparative form the figures for the previous fiscal year, all in
reasonable detail.  Such financial statements shall be accompanied by a report
and opinion thereon by independent public accountants of national standing
selected by the Company's Board of Directors.

            (c) The Company will furnish each Investor, as soon as practicable
after the end of the first, second and third quarterly accounting periods in
each fiscal year of the Company, and in any event within forty-five (45) days
thereafter, a balance sheet of the Company as of the end of each such quarterly
period, and a statement of income and a statement of cash flows of the Company
for such period and for the current fiscal year to date, prepared in accordance
with generally accepted accounting principles, with the exception that no notes
need be attached to such statements and year-end audit adjustments may not have
been made.

                                      13.
<PAGE>

          (d) So long as an Investor (with its Affiliates) shall own not less
than one million (1,000,000) shares of Registrable Securities (as adjusted for
stock splits, combinations and the like) (a "Major Investor"), the Company will
furnish each such Major Investor requesting such information as soon as
practicable after the end of each month, and in any event within twenty-one (21)
days thereafter, a balance sheet of the Company as of the end of each such month
and a statement of income and a statement of cash flows of the Company for such
month and for the current fiscal year to date prepared in accordance with
generally accepted accounting principles consistently applied, with the
exception that no notes need be attached to such statements and year-end audit
adjustments may not have been made.

  3.2     Inspection Rights.  Each Major Investor shall have the right to visit
and inspect any of the properties of the Company or any of its subsidiaries, and
to discuss the affairs, finances and accounts of the Company or any of its
subsidiaries with its officers, and to review such information as is reasonably
requested all at such reasonable times and as often as may be reasonably
requested; provided, however, that the Company shall not be obligated under this
Section 3.2 with respect to a competitor of the Company or with respect to
information which the Board of Directors determines in good faith is
confidential and should not, therefore, be disclosed.

  3.3     Confidentiality of Records. Each Investor agrees to use, and to use
its best efforts to insure that its authorized representatives use, the same
degree of care as such Investor uses to protect its own confidential information
to keep confidential any information furnished to it which the Company
identifies as being confidential or proprietary (so long as such information is
not in the public domain), except that such Investor may disclose such
proprietary or confidential information to any partner, subsidiary or parent of
such Investor for the purpose of evaluating its investment in the Company as
long as such partner, subsidiary or parent is advised of the confidentiality
provisions of this Section 3.3.

  3.4     Reservation of Common Stock.  The Company will at all times reserve
and keep available, solely for issuance and delivery upon the conversion of the
Preferred Stock, all Common Stock issuable from time to time upon such
conversion.

  3.5     Stock Vesting.  Unless otherwise approved by the Board of Directors,
all stock options and other stock equivalents issued after the date of this
Agreement to employees, directors, consultants and other service providers shall
be subject to vesting as follows:  (a) twenty-five percent (25%) of such stock
shall vest at the end of the first year following the earlier of the date of
issuance or such person's services commencement date with the company, and (b)
seventy-five percent (75%) of such stock shall vest over the remaining three (3)
years.  With respect to any shares of stock purchased by any such person, the
Company's repurchase option shall provide that upon such person's termination of
employment or service with the Company, with or without cause, the Company or
its assignee (to the extent permissible under applicable securities laws and
other laws) shall have the option to purchase at cost any unvested shares of
stock held by such person.

  3.6     Proprietary Information and Inventions Agreement.  The Company shall
require all employees to execute and deliver a Proprietary Information and
Inventions Agreement in the form attached to the Purchase Agreement.  The
Company shall require all consultants to

                                      14.
<PAGE>

execute and deliver an agreement containing confidentiality and other reasonably
protective provisions for the Company under the circumstances.

  3.7       Assignment of Right of First Refusal. In the event the Company
elects not to exercise any right of first refusal or right of first offer the
Company may have on a proposed transfer of any of the Company's outstanding
capital stock pursuant to the Company's charter documents, by contract or
otherwise, the Company shall, to the extent it may do so, assign such right of
first refusal or right of first offer to each Major Investor. In the event of
such assignment, each Major Investor shall have a right to purchase its pro rata
portion (as defined in Section 4.1) of the capital stock proposed to be
transferred.

  3.8       Termination of Covenants.  All covenants of the Company contained in
Section 3 of this Agreement shall expire and terminate as to each Investor upon
the earlier of (i) the effective date of the registration statement pertaining
to the Initial Offering or (ii) upon (a) the sale, lease or other disposition of
all or substantially all of the assets of the Company or (b) an acquisition of
the Company by another corporation or entity by consolidation, merger or other
reorganization in which the holders of the Company's outstanding voting stock
immediately prior to such transaction own, immediately after such transaction,
securities representing less than fifty percent (50%) of the voting power of the
corporation or other entity surviving such transaction, provided that this
Section 3.8(ii)(b) shall not apply to a merger effected exclusively for the
purpose of changing the domicile of the Company (a "Change in Control").

SECTION 4.  RIGHTS OF FIRST REFUSAL

  4.1       Subsequent Offerings.  So long as an Investor (with its Affiliates)
shall own not less than three hundred thousand (300,000) shares of Registrable
Securities (as adjusted for stock splits and combinations and the like) (a
"Significant Investor"), each such Significant Investor shall have a right of
first refusal to purchase its pro rata share of all Equity Securities, as
defined below, that the Company may, from time to time, propose to sell and
issue after the date of this Agreement, other than the Equity Securities
excluded by Section 4.7 hereof.  Each Investor's pro rata share is equal to the
ratio of (a) the number of shares of the Company's Common Stock (including all
shares of Common Stock issued or issuable upon conversion of the Shares) which
such Investor is deemed to be a holder immediately prior to the issuance of such
Equity Securities to (b) the total number of shares of the Company's outstanding
Common Stock (including all shares of Common Stock issued or issuable upon
conversion of the Shares or upon the exercise of any outstanding warrants or
options) immediately prior to the issuance of the Equity Securities.  The term
"Equity Securities" shall mean (i) any Common Stock, Preferred Stock or other
security of the Company, (ii) any security convertible, with or without
consideration, into any Common Stock, Preferred Stock or other security
(including any option to purchase such a convertible security), (iii) any
security carrying any warrant or right to subscribe to or purchase any Common
Stock, Preferred Stock or other security or (iv) any such warrant or right.

  4.2       Exercise of Rights.  If the Company proposes to issue any Equity
Securities, it shall give each Significant Investor written notice of its
intention, describing the Equity Securities, the price and the terms and
conditions upon which the Company proposes to issue the

                                      15.
<PAGE>

same. Each Significant Investor shall have fifteen (15) days from the giving of
such notice to agree to purchase its pro rata share of the Equity Securities for
the price and upon the terms and conditions specified in the notice by giving
written notice to the Company and stating therein the quantity of Equity
Securities to be purchased. Notwithstanding the foregoing, the Company shall not
be required to offer or sell such Equity Securities to any Significant Investor
who would cause the Company to be in violation of applicable federal securities
laws by virtue of such offer or sale.

  4.3     Issuance of Equity Securities to Other Persons.  If not all of the
Significant Investors elect to purchase their pro rata share of the Equity
Securities, then the Company shall promptly notify in writing the Significant
Investors who do so elect and shall offer such Significant Investors the right
to acquire such unsubscribed shares.  The Significant Investors shall have five
(5) days after receipt of such notice to notify the Company of its election to
purchase all or a portion thereof of the unsubscribed shares.  If the
Significant Investors fail to exercise in full the rights of first refusal, the
Company shall have ninety (90) days thereafter to sell the Equity Securities in
respect of which the Significant Investor's rights were not exercised, at a
price and upon general terms and conditions materially no more favorable to the
purchasers thereof than specified in the Company's notice to the Significant
Investors pursuant to Section 4.2 hereof.  If the Company has not sold such
Equity Securities within ninety (90) days of the notice provided pursuant to
Section 4.2, the Company shall not thereafter issue or sell any Equity
Securities, without first offering such securities to the Significant Investors
in the manner provided above.

  4.4     Sale Without Notice.  In lieu of giving notice to the Significant
Investors prior to the issuance of Equity Securities as provided in Section 4.2,
the Company may elect to give notice to the Significant Investors within thirty
(30) days after the issuance of Equity Securities.  Such notice shall describe
the type, price and terms of the Equity Securities.  Each Significant Investor
shall have twenty (20) days from the date of receipt of such notice to elect to
purchase its pro rata share of Equity Securities (as defined in Section 4.1, and
calculated before giving effect to the sale of the Equity Securities to the
purchasers thereof).  The closing of such sale shall occur within sixty (60)
days of the date of notice to the Significant Investors.

  4.5     Termination and Waiver of Rights of First Refusal.  The rights of
first refusal established by this Section 4 shall not apply to, and shall
terminate upon the earlier of (i) the effective date of the registration
statement pertaining to the Company's Initial Offering or (ii) a Change in
Control.  The rights of first refusal established by this Section 4 may be
amended, or any provision waived with the written consent of Significant
Investors holding a majority of the Registrable Securities held by all
Significant Investors, or as permitted by Section 5.6.

  4.6     Transfer of Rights of First Refusal.  The rights of first refusal of
each Significant Investor under this Section 4 may be transferred to the same
parties, subject to the same restrictions as any transfer of registration rights
pursuant to Section 2.10.

                                      16.
<PAGE>

     4.7  Excluded Securities. The rights of first refusal established by this
Section 4 shall have no application to any of the following Equity Securities:

          (a)  shares of Common Stock (and/or options, warrants or other Common
Stock purchase rights issued pursuant to such options, warrants or other rights)
issued or to be issued after the Original Issue Date (as defined in the
Company's Certificates of Incorporation) to employees, officers or directors of,
or consultants or advisors to the Company or any subsidiary, pursuant to stock
purchase or stock option plans or other arrangements that are approved by the
Board of Directors;

          (b)  stock issued pursuant to any rights or agreements outstanding as
of the date of this Agreement, options and warrants outstanding as of the date
of this Agreement, and stock issued pursuant to any such rights or agreements
granted after the date of this Agreement; provided that the rights of first
refusal established by this Section 4 applied with respect to the initial sale
or grant by the Company of such rights or agreements;

          (c)  any Equity Securities issued for consideration other than cash
pursuant to a merger, consolidation, acquisition or similar business
combination;

          (d)  shares of Common Stock issued in connection with any stock split,
stock dividend or recapitalization by the Company;

          (e)  shares of Common Stock issued upon conversion of the Shares;

          (f)  any Equity Securities issued pursuant to any equipment leasing or
loan arrangement, or debt financing from a bank or similar financial or lending
institution;

          (g)  any Equity Securities that are issued by the Company pursuant to
a registration statement filed under the Securities Act; and

          (h)  shares of the Company's Common Stock or Preferred Stock issued in
connection with strategic transactions involving the Company and other entities,
including (i) joint ventures, manufacturing, marketing or distribution
arrangements or (ii) technology transfer or development arrangements; provided
that such strategic transactions and the issuance of shares therein, has been
approved by the Company's Board of Directors.

                                 MERCATA, INC.

                    AMENDED AND RESTATED CO-SALE AGREEMENT


     This Amended and Restated Co-Sale Agreement (the "Agreement") is made and
entered into as of this lst day of March, 2000, by and among Mercata, Inc., a
Delaware corporation (the "Company"), each of the persons and entities listed on
Exhibit A hereto (the "Investors"), and Vulcan Ventures Incorporated (referred
to herein as the "Founder").

                                   Recitals

     Whereas, the Founder is the beneficial owner of an aggregate of one million
(1,000,000) shares of Common Stock of the Company, fourteen million (14,000,000)
shares of Series A Preferred Stock of the Company, one million eight hundred
eighty-eight thousand (1,888,000) shares of Series B Preferred Stock of the
Company and three million three hundred sixty-three thousand (3,363,000) shares
of Series C Preferred Stock of the Company;

     Whereas, the Company, the Founder and the Investors that have entered into
that certain Co-Sale Agreement, dated as of September 30, 1999, as amended (the
"Prior Co-Sale Agreement"), and desire to amend and restate such agreement with
the terms and conditions of this agreement;

     Whereas, Investors are purchasing shares of the Company's Series C
Preferred Stock (the "Series C Preferred Stock") pursuant to that certain Series
C Preferred Stock Purchase Agreement (the "Purchase Agreement") of even date
herewith;

     Whereas, such Investors were induced by the Company to purchase the Series
C Preferred Stock in part by the Company's and the Founder's agreement to enter
into this Agreement; and

     Whereas, the parties desire to enter into this Agreement in order to
grant rights of co-sale to each Investor.

     Now, Therefore, in consideration of the mutual promises, representations,
warranties, covenants and conditions set forth in this Agreement and the
Purchase Agreement and for other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the parties agree hereto as
follows:

     1.   Definitions.

          (a)  "Co-Sale Stock" shall mean shares of the Company's Common Stock
and Preferred Stock now owned or subsequently acquired by the Founder by gift,
purchase, dividend, option exercise or any other means whether or not such
securities are only registered in a Founder's name or beneficially or legally
owned by Founder, including any interest of a spouse in any of the Co-Sale
Stock, whether that interest is asserted pursuant to marital property laws or
otherwise. The number of shares of Co-Sale Stock owned by the Founder as of the
date hereof are set forth on Exhibit B, which Exhibit may be amended from time
to time by the Company

                                       1.
<PAGE>

to reflect changes in the number of shares owned by the Founder, but the failure
to so amend shall have no effect on such Co-Sale Stock being subject to this
Agreement.

          (b)  "Common Stock" shall mean the Company's Common Stock and shares
of Common Stock issued or issuable upon exercise of any option, warrant or other
security or right of any kind convertible into or exchangeable for Common Stock.

          (c)  "Preferred Stock" shall mean the Company's Preferred Stock and
shares of Preferred Stock issued or issuable upon exercise of any option,
warrant or other security or right of any kind convertible into or exchangeable
for Preferred Stock.

          (d)  For the purpose of this Agreement, the term "Transfer" shall
include any sale, assignment, encumbrance, hypothecation, pledge, conveyance in
trust, gift, transfer by request, devise or descent, or other transfer or
disposition of any kind, including, but not limited to, transfers to receivers,
levying creditors, trustees or receivers in bankruptcy proceedings or general
assignees for the benefit of creditors, whether voluntary or by operation of
law, directly or indirectly, of any of the Co-Sale Stock.

          (e)  "Affiliate" of a person or entity means any person or entity who
controls, is controlled by or under common control with such person or entity.

     2.   Transfers by the Founder.

          (a)  If the Founder proposes to Transfer any shares of Co-Sale Stock
then the Founder shall promptly give written notice (the "Notice")
simultaneously to the Company and to each of the Investors at least thirty (30)
days prior to the closing of such Transfer. The Notice shall describe in
reasonable detail the proposed Transfer including, without limitation, the
number of shares of Co-Sale Stock to be transferred, the nature of such
Transfer, the consideration to be paid, and the name and address of each
prospective purchaser or transferee. In the event that the Transfer is being
made pursuant to the provisions of Section 3(a), the Notice shall state under
which section the Transfer is being made.

          (b)  Each Investor shall have the right, exercisable upon written
notice to the Founder within fifteen (15) days after the Notice, to participate
in such Transfer of Co-Sale Stock on the same terms and conditions. Such notice
shall indicate the number of shares of Common Stock and/or Preferred Stock such
Investor wishes to sell under his or her right to participate. To the extent one
or more of the Investors exercise such right of participation in accordance with
the terms and conditions set forth below, the number of shares of Co-Sale Stock
that the Founder may sell in the transaction shall be correspondingly reduced.

          (c)  Each Investor may sell all or any part of that number of shares
equal to the product obtained by multiplying (i) the aggregate number of shares
of Co-Sale Stock covered by the Notice by (ii) a fraction the numerator of which
is the number of shares of Common Stock (including shares of Preferred Stock on
an as converted basis) owned by such Investor at the time of the Transfer and
the denominator of which is the total number of shares of Common Stock
(including shares of Preferred Stock on an as converted basis) owned by Founder
and the Investors at the time of the Transfer.

                                       2.
<PAGE>

          (d)  Each Investor who elects to participate in the Transfer pursuant
to this Section 2 (a "Participant") shall effect its participation in the
Transfer by promptly delivering to Founder for transfer to the prospective
purchaser one or more certificates, properly endorsed for transfer, which
represent:

               (i)   the type and number of shares of Common Stock and/or
Preferred Stock which such Participant elects to sell; or

               (ii)  that number of shares of Preferred Stock which is at such
time convertible into the number of shares of Common Stock which such
Participant elects to sell; provided, however, that if the prospective purchaser
objects to the delivery of Preferred Stock in lieu of Common Stock, such
Participant shall convert such Preferred Stock into Common Stock and deliver
Common Stock as provided in Section 2(d)(i) above. The Company agrees to make
any such conversion concurrent with the actual transfer of such shares to the
purchaser.

          (e)  The stock certificate or certificates that the Participant
delivers to Founder pursuant to Section 2(d) shall be transferred to the
prospective purchaser in consummation of the sale of the Common Stock pursuant
to the terms and conditions specified in the Notice, and the Founder shall
concurrently therewith remit to such Participant that portion of the sale
proceeds to which such Participant is entitled by reason of its participation in
such sale. To the extent that any prospective purchaser or purchasers prohibits
such assignment or otherwise refuses to purchase shares or other securities from
a Participant exercising its rights of co-sale hereunder, the Founder shall not
sell to such prospective purchaser or purchasers any Co-Sale Stock unless and
until, simultaneously with such sale, the Founder shall purchase such shares or
other securities from such Participant on the same terms and conditions
specified in the Notice.

          (f)  The exercise or non-exercise of the rights of the Investors
hereunder to participate in one or more Transfers of Co-Sale Stock made by the
Founder shall not adversely affect their rights to participate in subsequent
Transfers of Co-Sale Stock subject to Section 2(a).

          (g)  If none of the Investors elect to participate in the sale of the
Co-Sale Stock subject to the Notice, the Founder may, not later than sixty (60)
days following delivery to the Company of the Notice, enter into an agreement
providing for the closing of the Transfer of the Co-Sale Stock covered by the
Notice within thirty (30) days of such agreement on terms and conditions not
more materially favorable to the transferor than those described in the Notice.
Any proposed transfer on terms and conditions materially more favorable than
those described in the Notice, as well as any subsequent proposed transfer of
any of the Co-Sale Stock by Founder, shall again be subject to the co-sale
rights of the Investors and shall require compliance by Founder with the
procedures described in this Section 2.

     3.   Exempt Transfers.

          (a)  Notwithstanding the foregoing, the co-sale rights of the
Investors shall not apply to (i) any transfer to the ancestors, descendants or
spouse or to trusts for the benefit of such persons or the Founder, (ii) any
transfer or transfers by a Founder to another Founder (the "Transferee-Founder")
so long as the Transferee-Founder is, at the time of the transfer, employed by
or acting as a consultant or director of the Company, (iii) any pledge of Co-
Sale

                                       3.
<PAGE>

Stock made pursuant to a bona fide loan transaction that creates a mere security
interest, (iv) any bona fide gift, or (v) any transfer to an Affiliate; provided
that in the event of any transfer made pursuant to one of the exemptions
provided above, (A) the Founder shall inform the Investors of such pledge,
transfer or gift prior to effecting it and (B) the pledgee, transferee or donee
shall furnish the Investors with a written agreement to be bound by and comply
with all provisions of Section 2. Except with respect to Co-Sale Stock
transferred under clause (i) above (which Co-Sale Stock shall no longer be
subject to the co-sale rights of the Investors), such transferred Co-Sale Stock
shall remain "Co-Sale Stock" hereunder, and such pledgee, transferee or donee
shall be treated as the "Founder" for purposes of this Agreement.

          (b)  Notwithstanding the foregoing, the provisions of Section 2 shall
not apply to the sale of any Co-Sale Stock to the public pursuant to a
registration statement filed with, and declared effective by, the Securities and
Exchange Commission under the Securities Act of 1933, as amended (the
"Securities Act").

          (c)  This Agreement is subject to, and shall in no manner limit the
right which the Company may have to repurchase securities from the Founder
pursuant to (i) a stock restriction agreement or other agreement between the
Company and the Founder and (ii) any right of first refusal set forth in the
Bylaws of the Company.

     4.   Prohibited Transfers.

          (a)  In the event that Founder should Transfer any Co-Sale Stock in
contravention of the co-sale rights of each Investor under this Agreement (a
"Prohibited Transfer"), each Investor, in addition to such other remedies as may
be available at law, in equity or hereunder, shall have the put option provided
below, and the Founder shall be bound by the applicable provisions of such
option.

          (b)  In the event of a Prohibited Transfer, each Investor shall have
the right to sell to Founder the type and number of shares of Common Stock equal
to the number of shares each Investor would have been entitled to transfer to
the purchaser under Section 2(c) hereof had the Prohibited Transfer been
effected pursuant to and in compliance with the terms hereof. Such sale shall be
made on the following terms and conditions:

               (i)   The price per share at which the shares are to be sold to
the Founder shall be equal to the price per share paid by the purchaser to the
Founder in such Prohibited Transfer. The Founder shall also reimburse each
Investor for any and all fees and expenses, including legal fees and expenses,
incurred pursuant to the exercise or the attempted exercise of the Investor's
rights under Section 2.

               (ii)  Within ninety (90) days after the date on which an Investor
received notice of the Prohibited Transfer or otherwise became aware of the
Prohibited Transfer, such Investor shall, if exercising the option created
hereby, deliver to the Founder the certificate or certificates representing
shares to be sold, each certificate to be properly endorsed for transfer.

               (iii) The Founder shall, upon receipt of the certificate or
certificates for the shares to be sold by an Investor, pursuant to this Section
4(b), pay the aggregate purchase

                                       4.
<PAGE>

price therefor and the amount of reimbursable fees and expenses, as specified in
Section 4(b)(i), in cash or by other means acceptable to the Investor.

               (iv)  Notwithstanding the foregoing, any attempt by a Founder to
transfer Co-Sale Stock in violation of Section 2 hereof shall be voidable at the
option of a majority in interest of the Investors if the Investors do not elect
to exercise the put option set forth in this Section 4, and the Company agrees
it will not effect such a transfer nor will it treat any alleged transferee as
the holder of such shares without the written consent of a majority in interest
of the Investors.

     5.   Legend.

          (a)  Each certificate representing shares of Co-Sale Stock now or
hereafter owned by the Founder or issued to any person in connection with a
transfer pursuant to Section 3(a) hereof shall be endorsed with the following
legend:

               "THE SALE, PLEDGE, HYPOTHECATION OR TRANSFER OF THE
     SECURITIES REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO THE
     TERMS AND CONDITIONS OF A CERTAIN CO-SALE AGREEMENT BY AND
     BETWEEN THE SHAREHOLDER, THE COMPANY AND CERTAIN HOLDERS OF STOCK
     OF THE COMPANY. COPIES OF SUCH AGREEMENT MAY BE OBTAINED UPON
     WRITTEN REQUEST TO THE SECRETARY OF THE COMPANY."

          (b)  The Founder agrees that the Company may instruct its transfer
agent to impose transfer restrictions on the shares represented by certificates
bearing the legend referred to in Section 5(a) above to enforce the provisions
of this Agreement and the Company agrees to promptly do so. The legend shall be
removed upon termination of this Agreement.

     6.   Miscellaneous.

          (a)  Conditions to Exercise of Rights. Exercise of the Investors'
rights under this Agreement shall be subject to and conditioned upon, and the
Founder and the Company shall use their best efforts to assist each Investor in,
compliance with applicable laws.

          (b)  Governing Law. This Agreement shall be governed by and construed
under the laws of the State of Washington as applied to agreements among
Washington residents entered into and to be performed entirely within
Washington.

          (c)  Amendment. Any provision of this Agreement may be amended and the
observance thereof may be waived (either generally or in a particular instance
and either retroactively or prospectively), only by the written consent of (i)
as to the Company, only the Company, (ii) as to the Investors, persons holding
more than a majority in interest of the Common Stock (including shares of
Preferred Stock on an as converted basis) held by the Investors and their
assignees, pursuant to Section 6(d) hereof, and (iii) as to the Founder, only
the Founder; provided, that no consent of the Founder shall be necessary for any

Stock or other preferred stock of the Company as "Investors" and parties hereto.

binding upon each Investor, its successors and assigns, the Company and the
Founder.

          (d)  Assignment of Rights. This Agreement constitutes the entire
agreement between the parties relative to the specific subject matter hereof.
Any previous agreement among the parties relative to the specific subject matter
hereof is superseded by this Agreement. This Agreement and the rights and
obligations of the parties hereunder shall inure to the benefit of, and be
binding upon, their respective successors, assigns and legal representatives.
Each Investor may transfer or assign its rights hereunder only along with the
corresponding shares of Common Stock or Preferred Stock and any purported

          (e)  Term. This Agreement shall continue in full force and effect from
the date hereof through the earliest of the following dates, on which date it
shall terminate in its entirety:

               (i)  the date of the closing of a firmly underwritten public
offering of the Common Stock pursuant to a registration statement filed with the
Securities and Exchange Commission, and declared effective under the Securities
Act of 1933, as amended;

               (ii) the date of the closing of a sale, lease, or other
disposition of all or substantially all of the Company's assets or the Company's
merger into or consolidation with any other corporation or other entity, or any
other corporate reorganization, in which the holders of the Company's
outstanding voting stock immediately prior to such transaction own, immediately
after such transaction, securities representing less than fifty percent (50%) of
the voting power of the corporation or other entity surviving such transaction,
provided, that this Section 6(e)(ii) shall not apply to a merger effected
exclusively for the purpose of changing the domicile of the Company; or

          (f)  the date as of which the parties hereto terminate this Agreement
by written consent of a majority in interest of the Investors (excluding Vulcan)
and a majority in interest of the Founder.

          (g)  Notices.  All notices required or permitted hereunder shall be in
writing and shall be deemed effectively given: (i) upon personal delivery to the

          (h)  Severability.  In the event one or more of the provisions of this
Agreement should, for any reason, be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality, or unenforceability
shall not affect any other provisions of this

                                       6.
<PAGE>

Agreement, and this Agreement shall be construed as if such invalid, illegal or
unenforceable provision had never been contained herein.

          (i)  Attorneys' Fees. In the event that any suit or action is
instituted to enforce any provision in this Agreement, the prevailing party in
such dispute shall be entitled to recover from the losing party all fees, costs
and expenses of enforcing any right of such prevailing party under or with
respect to this Agreement, including without limitation, such reasonable fees
and expenses of attorneys and accountants, which shall include, without
limitation, all fees, costs and expenses of appeals.

          (j)  Entire Agreement. This Agreement and the Exhibits hereto, along
with the Purchase Agreement and each of the Exhibits thereto, constitute the
full and entire understanding and agreement between the parties with regard to
the subjects hereof and thereof and no party shall be liable or bound to any
other in any manner by any representations, warranties, covenants and agreements
except as specifically set forth herein and therein.

          (k)  Additional Investors.  Notwithstanding anything to the contrary
contained herein, if the Company shall issue additional shares of its Series C
Preferred Stock pursuant to the Purchase Agreement, any purchaser of such shares
of Series C Preferred Stock may become a party to this Agreement by executing
and delivering an additional counterpart signature page to this Agreement and
shall be deemed an "Investor" hereunder.

          (l)  Counterparts.  This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

          (m)  Amendment of Prior Co-Sale Agreement. The Prior Co-Sale Agreement
is hereby amended in its entirety herein. Such amendment and restatement is
effective upon the execution of this Agreement by the Company, the Founders and
the holders of a majority in interest of the Common Stock (on an as converted
basis) held by the Investors and their assigns outstanding as of the date of
this Agreement. Upon such execution, all provisions of, rights granted and
covenants made in the Prior Co-Sale Agreement are hereby waived, released and
amended in their entirety and shall have no further force or effect.

Revenue Share:
Until such time as Mercata is able to track transaction revenue based on the
origin of each customer visit, the revenue shares under this agreement shall be
based on the percentage of Mercata's overall monthly net sales likely to have
resulted from Go2Net links. This percentage will be calculated by Mercata based
on the percentage of overall user sessions received through links from the
Go2Net site. Such percentage will be applied to Mercata's overall net sales on a
monthly basis to get the net sales permanently attributable to Go2Net. Go2Net's
revenue share will be [...***...] of such presumed net sale. The parties agree
not to artificially inflate the number of reported click throughs by their own
visits to the linked web page or other inappropriate means.
- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------
Impression Delivery Guarantee:
Go2Net agrees to guarantee Mercata [...***...] impressions over the course of

Within 3 business days of the first of each month, Go2Net will provide Mercata

will provide Go2Net with monthly reports accurately stating overall user
sessions per month and overall sales, and will present Go2Net with calculations
specifying the portion of net sales presumably attributable to Go2Net (per the
formula above), upon which the [...***...] revenue share will be applied.
Mercata's overall traffic, sales data and customer information is highly
confidential and proprietary to Mercata. As such, Go2Net agrees to hold all such
information in strict confidence and only use it for the purposes of reviewing
the revenue share calculations provided by Mercata. Either party shall have the
right, at its own expense and upon reasonable notice, to audit reports supplied
by the other party and the party supplying the reports in question shall
cooperate in good faith to facilitate any audit that is requested.

    the right of any party, including the plaintiff, to submit the controversy
    or claim to arbitration.

    is tried, heard or decided, including the court which hears any exceptions
    made to an arbitration award submitted to it for confirmation as a judgment
    (with respect to attorneys' fees incurred in such confirmation proceedings),

          ----------
Advertiser shall be entitled to the additional promotions and media specified in
the attached Schedule A, which is incorporated herein by reference.

     3.   Fees and Payment Schedule.  In consideration for the commercial time
          ---- --- ------- --------
and additional promotions and media to be received by Advertiser hereunder,
Advertiser agrees to pay a non-cancelable Annual Fee for each NBA season covered
by this Agreement and to pay a non-cancelable Additional Playoff Fee for each
playoff game in accordance with the following:

          (a)

          (b)  The Annual Fee is payable as follows: TBI will send invoices to

     4.   Protection and Operative Clauses.
          ---------- --- --------- -------

          (a) No rights of exclusivity are granted to Advertiser by this
Agreement and nothing contained herein shall limit in any manner the rights of
the Trail Blazers to sell commercial time during any of its telecasts for
advertisements to any other entity or for the advertisement of any product or
service.

          (b) The script and tone of any advertising must conform to the
policies of the Trail Blazers and the telecasting station, each of which shall
have the continuing right to reject or edit telecast material to the extent
necessary to conform to such policies and as may be in the public interest.  In
addition, Advertiser acknowledges that the Trail Blazers maintain a variety of
commercial relationships and, therefore, in the interest of protecting the
interests of all its sponsors, the Trail Blazers have the unilateral discretion
to reject advertising based on product category exclusivity, the incompatibility
or antithetical nature of the advertising, the tenor and object of the
advertising, or the promotion of a product or service either not in the category
for which Advertiser contracted or of an entity other than Advertiser.  If any
advertising is so rejected, the Trail Blazers will provide Advertiser with 10
days' written notice of such rejection to allow Advertiser to furnish suitable
substitute advertising prior to the next scheduled telecast.  Advertiser will be
entitled to a pro rata refund or a make good for any commercials it does not
receive as a result of such rejection.

          (c) All advertisements will be in the form of videotape recordings,
half-inch, three-fourths-inch, one-inch or Beta format.  Advertiser shall be
responsible for the content and quality of all commercial materials.  All
advertising and commercial code-traffic instructions shall be delivered to the
Trail Blazers 10 days prior to telecast.  Advertiser may change the content on 7
days' advance notice.

          (d) If Advertiser's telecast material or code-traffic instructions are
not furnished by Advertiser in a timely manner, the Trail Blazers may utilize
any previously furnished material of Advertiser to fill spots reserved for
Advertiser for upcoming telecasts.  No requirement as to air time product
separation regarding the scheduling of advertisements for competitive products
applies to this Agreement.  Unless otherwise stated herein, no exclusivity
rights are granted to Advertiser.

          (e) Advertiser will receive written deadline and specifications for
any print media referenced in this Agreement.  Advertiser shall be responsible
for the content and quality of any print commercial productions.  If
Advertiser's printed material is not furnished in a timely manner, the benefits
in this Agreement which involve printed material will be forfeited with no
financial rebates.

          (f) All advertising material furnished to the Trail Blazers which is
not retrieved by Advertiser within two months following the end of the term of
this Agreement shall become the property of the Trail Blazers.  This paragraph
is not intended to, nor shall it be construed to, give TBI any right, title or
interest in any of the trademarks, trade names, advertising slogans or
copyrighted material belonging to Advertiser, nor does this paragraph give TBI
use of the Advertising materials for any purpose other than to the extent
permitted herein during the term of this Agreement or the destruction of such
materials.

reasonable use of TBI's name, trade names, trademarks and logos in connection
with advertising by Advertiser in the state of Oregon and the Portland, Oregon
metropolitan area; provided, however, that Advertiser shall only do so with the
prior written approval of TBI, which approval may be withheld in TBl's sole
discretion, and provided further that any advertising material making use of

understands and agrees that Advertiser is the exclusive owner of Advertiser's
proprietary business models and technology, including but not limited to its

method of demand aggregation.  However, Advertiser grants TBI a royalty-free,

state of Oregon.

          (i)  (1)  Advertiser shall indemnify, defend, and hold the Trail
Blazers harmless from and against any and all claims, damages, loss, liability
or expense, including attorneys' fees and the cost of any legal proceedings,
arising out of the advertisements furnished by Advertiser, including but not
limited to claims, actions or proceedings, and any appeal, for libel, slander,
invasion of privacy, infringement of copyright or license, unfair or improper
trade practices, other wrongful business conduct, or conduct in violation of the
rules and regulations of the Federal Trade Commission and analogous state
agencies. This indemnity shall specifically extend to the television station
telecasting such advertisements.

               (2)  TBI shall indemnify, defend, and hold Advertiser harmless
from and against any and all claims, damages, loss, liability or expense,
including attorney fees and the cost of any legal proceedings, arising out of
TBI's improper use of the advertisements, trademarks, trade names or logos
furnished by Advertiser.

          (j)  If legal proceedings or arbitration proceedings are initiated by
either party to enforce or interpret this Agreement, the party prevailing in any
suit, action or proceeding, and in any appeal therefrom, shall be entitled to
recover its reasonable attorney fees as fixed by the court in which the action
is tried or in which the appeal is heard or by the arbitrator who hears the
proceeding.  Additionally, in the event that Advertiser seeks the protection of
or becomes the subject of proceedings in the United States Bankruptcy Court, the
Trail Blazers shall be entitled to recover its reasonable attorney fees incurred
in such proceedings as fixed by such court.

          (k)  If after 7 days advance written notice from TBI, Advertiser fails
to pay any overdue invoice (a "Default"), the entire Annual Fee for the
remainder of the term of this Agreement shall become immediately due and
payable.  If the entire Annual Fee is not paid within 7 days of receipt by
Advertiser of a notice of Default, the Trail Blazers may immediately terminate
this Agreement in addition to seeking whatever other relief is afforded by
applicable law.

          (l)  Either party may terminate this Agreement upon the cancellation
or termination of the Trail Blazers' NBA franchise or the relocation of the
Trail Blazers' franchise to a location more than 50 miles from Portland, Oregon.
In such event, Advertiser will receive a pro rata refund based upon the number
of commercials not delivered.

                                      -3-

          (m)  In no event shall either party be liable for any special,
incidental, or consequential damages or loss of profits arising out of or
relating to any breach of this Agreement.  The exclusive remedies for Advertiser
in the event of a breach by TBI shall be a suitable make good and a pro rata
compensating credit for lost time.

          (n)  Neither this Agreement nor the rights hereunder may be assigned
by Advertiser without the prior written consent of the Trail Blazers which
consent may be withheld in the sole discretion of the Trail Blazers.

     5.   Right of Refusal.  Subject to another advertiser purchasing
          ----- -- -------
exclusivity in the retail e-commerce web site category, Advertiser shall have a
right of first refusal with respect to advertising time offered by the Trail
Blazers for local telecasts of selected games for the 2000-2001 season, on terms

apply to placements the same as those provided for in this Agreement and must be
exercised by executing and returning to the Trail Blazers the Letter Agreement

Advertiser or Advertiser's agent.

Constitution and Bylaws and other rules and regulations of the National
Basketball Association as they presently exist or as they may from time to time

1.   Term And Termination.

1.1  This Agreement will begin on the Agreement Date and end one year from the

Notwithstanding any other provision of this Agreement, Merchant may terminate
any Optional BFAST Service upon 60 days written notice to Be Free.  Sections
1.1, 2.1, 3.3, 4..1, 4.2, 5, 6, 7.4, 7.5, 7.6 and 7.7 shall survive any
expiration or termination of this Agreement.

1.2  Provided that a party is not in default of any payment or other material
breach, that party may terminate this Agreement upon 60 days written notice (the
"Notice Period") upon any material breach or default of a provision of this
Agreement by the other party.  Any termination under this section shall become
effective at the end of the Notice Period unless the party in violation cures
the material breach or default, or has commenced reasonable efforts to cure the
breach or default within such period.

Clickthrough requests at a rate not greater than the expected peak request rate

"Performance Obligation").  Due to the complexity of the Internet, the
variability of user hardware and software capabilities and the provision of
services to End Users by various providers, Be Free does not guarantee end-to-
end response times or transmission rates.  Should Be Free fail to provide
services in accordance with the Performance Obligation for greater than 60

audit.  Such accounting firm shall be required to sign an agreement protecting

the accuracy of the Merchant's Transaction File for the period requested.  Be
Free shall bear the costs of the audit unless it is determined by the auditor

underpayment of BFAST Service Fees in any calendar quarter period.  In such
event, Merchant shall bear the reasonable costs of the audit for the period
requested.

party (i) promptly notifies the indemnifying party in writing of any such claim;
(ii) gives the indemnifying party full control of the defense and settlement of

of the Affiliate Sales Channel and, specifically, shall not disclose any trade
secret or confidential business information at any time to any third party

network supported by BeFree pursuant to this Agreement.  Such network consists
of affiliate sites that carry offers and links for products or services of
Merchant in exchange for payment based on the traffic to or sales generated by
such advertisement or promotion pursuant to a set of terms that are
substantially standard (e.g., negotiated relationships with strategic partners,
relationships with advertising agencies and direct marketing activities would
all be outside of the Sales Affiliate Program).

7.2  The parties agree to announce this Agreement shortly after the its
execution.  Each party shall have the right to approve the other party's
announcement before it is made public, which approval shall not unreasonably be
withheld.

acquiring company.  Any attempted assignment in contravention of this section
shall be null and void.

WARRANTIES, WHETHER WRITTEN OR ORAL, EXPRESS OR IMPLIED, REGARDING THIS
AGREEMENT'S SUBJECT MATTER.  EACH PARTY HEREBY DISCLAIMS ALL WARRANTIES IMPLIED
IN LAW OR OTHERWISE, INCLUDING WITHOUT LIMITATION, IMPLIED WARRANTIES OF
MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE.

7.5  Other than breaches of Section 6 (Confidentiality) and the indemnification
obligations in Section 4, it is expressly agreed that, in the event of any
breach or purported breach of this Agreement, the remedy shall be limited to
equitable remedies or an action at law for money damages, if any were actually
suffered.  OTHER THAN BREACHES OF SECTION 6 (CONFIDENTIALITY) AND THE
INDENIFICATION OBLIGATIONS IN SECTION 4, NEITHER PARTY SHALL BE LIABLE UNDER
THIS AGREEMENT FOR ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL OR PUNITIVE DAMAGES,
WHETHER SUCH LIABILITY IS ASSERTED ON THE BASIS OF CONTRACT, TORT (INCLUDING
NEGLIGENCE OR STRICT LIABILITY) OR OTHERWISE, EVEN IF THE OTHER PARTY HAS WARNED
OF THE POSSIBILITY OF SUCH DAMAGES.

7.6  Neither party shall be liable to the other party for any delay or default
hereunder to the extent due to any cause beyond its reasonable control, if such
party notifies the other of the cause and the expected duration of such delay or
default.  All such obligations shall return to full force and effect upon the
termination of such cause.  A "cause beyond the reasonable control" includes any
act of God, act of any government authority, labor dispute, fire, explosion,
accident, power failure, flood, riot or declared or undeclared war.

7.7  This Agreement is the entire agreement between the parties regarding its
subject matter, supersedes any other agreements or understandings between them,
and may only be amended by a writing signed by both parties.  A party's waiver
of, or failure to enforce, any right hereunder on one occasion shall not be
deemed a waiver of any other right on the same occasion or the same right on any
other occasion.  If a court having competent jurisdiction declares any provision
of this Agreement invalid or unenforceable, the remainder of this Agreement
shall continue in full force and effect.  This Agreement shall be construed and
governed according to the laws of Commonwealth of Massachusetts applicable to
contracts made, and fully performed, in Massachusetts.

this Agreement, each party shall promptly deliver to the other party all of the
other party's Confidential Information.

6.   Limitation of Liability

Agreement.

EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, CYBERSOURCE HEREBY SPECIFICALLY
DISCLAIMS ANY REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED, REGARDING THE

PARTICULAR PURPOSE AND NON-INFRINGEMENT AND ANY IMPLIED WARRANTIES ARISING FROM

8.   Indemnification
     ---------------

a)   Subject to Section 6 of this Agreement, each Party (the "Indemnifying
Party") will defend at its expense any legal cause of action brought against the
other party (the "Indemnified Party"), to the extent that such cause of action
is based upon a claim that any services or products of the Indemnifying Party
provided hereunder infringe a copyright, United States patent, trade secret, or
other intellectual property rights of a third party (other than claims relating
to conducting internet commerce generally). The Indemnifying Party will pay
those costs and damages finally awarded against the Indemnified Party which are
attributable to any such claim, provided that (i) Indemnified Party notifies
Indemnifying Party in writing immediately after Indemnified Party becomes aware
of such claim or the possibility thereof, and, (ii) Indemnifying Party has sole
control of the settlement, compromise, negotiation, and defense of any such
action; and, (iii) Indemnified Party cooperates in good faith, in the defense of
any such legal action.

Indemnifying Party's opinion is highly likely to become, the subject of a

                                      2.
<PAGE>

claim of infringement, Indemnifying Party may, at its option, (i) obtain the
right for Indemnified Party to continue using the Services; (ii) replace or
modify the Indemnifying Party's products and services so it is no longer
infringing or reduces the likelihood that it will be determined to be
infringing, or (iii) if neither of the foregoing options is commercially
reasonable, terminate this Agreement, provided that Indemnifying Party refunds
any fees received from or remits any amounts due to Indemnified Party hereunder,
whichever applicable.

c)   Indemnifying Party shall have no liability for any claim of infringement
based on (i) products or services of the Indemnifying Party which have been
modified by parties other than Indemnifying Party; (ii) Indemnified Party's use
of Indemnifying Party's products or services in conjunction with data where use
with such data gave rise to the infringement claim; or (iii) Indemnified Party's
use of Indemnifying Party's products or services with non-Indemnifying Party
software or hardware, where use with such other software or hardware gave rise
to the infringement claim.

9.   Marketing
     ---------

CyberSource shall be entitled to disclose the existence of the relationship
formed hereunder between Customer and CyberSource through the use of media
releases, public announcements, and customer reference materials. CyberSource
agrees to use commercially reasonable efforts to coordinate the release of its
announcements in conjunction with related announcements of the other party.
Customer hereby grants CyberSource a limited, non-exclusive, non-transferable
royalty-free license to use its trademarks and service marks solely for the
issuance of media releases and public announcements; provided that CyberSource
agrees to change, at CyberSource's expense, any displays of Logos which Customer
reasonably determines to be a misuse of Licensor's Logos.

10.  Relationship of Parties
     -----------------------

The parties shall perform all of their duties under this Agreement as
independent contractors. Nothing in this Agreement shall be construed to give
either party the power to direct or control the daily activities of the other
party, or to constitute the parties as principal and agent, employer and
employee, franchiser and franchiseee, partners, joint venturers, co-owners, or
otherwise as participants in a joint undertaking. The parties understand and
agree that, except as specifically provided in this Agreement, neither party
grants the other party the power or authority to make or give any agreement,
statement, representation, warranty, or other commitment on behalf of the other
party, or to enter into any contract or otherwise incur any liability or
obligation, express or implied, on behalf of the other party, or to transfer,
release, or waive any right, title, or interest of such other party.

11.  Government Law; Consent to Jurisdiction
     ---------------------------------------

This Agreement will be deemed entered into in California and will be governed by
and interpreted in accordance with the laws of the State of California,
excluding (i) that body of law known as conflicts of law and (ii) the United
Nations Convention on Contracts for the International Sale of Goods. The parties
agree that any dispute arising under this Agreement, which is not subject to
Section 12 below, will be resolved in the state or federal courts in Santa Clara
County, California, and the parties hereby expressly consent to jurisdiction
therein.

12.  Arbitration
     -----------

a)   Except that the parties shall be entitled to apply to the courts for
mandatory or injunctive equitable relief, any controversy or claim arising out
of or relating to this Agreement, or the breach thereof, will be settled by
arbitration before three (3) arbitrators in accordance with the rules then
prevailing of the American Arbitration Association, and judgment upon the reward
rendered by the arbitrators may be entered in any court having jurisdiction
thereof. In any such proceeding the arbitrators shall make every reasonable
effort to resolve the matter expeditiously and to reduce the costs of the
proceeding, by limiting discovery and other means; and neither party shall be
entitled under any circumstances to receive punitive exemplary damages. Unless
the parties otherwise agree in writing, such arbitration shall be conducted in
San Jose, California, and the parties consent to jurisdiction and venue in the
courts of California located in Santa Clara County, California. Judgment of
arbitrator shall be final and binding. Each party hereto waives its right to an
appeal and/or a jury.

13.  Assignment
     ----------

This Agreement may not be transferred to assigned by either party without the
prior written consent of the other party, which consent shall not be
unreasonably withheld. Notwithstanding the foregoing, consent of the other party
shall not be required for assignment or transfer made by (i) operation of law or
(ii) to an entity that acquires substantially all of its stock, assets or
business.

14.  Employee Hiring
     ---------------

During the term of this Agreement and for six (6) months thereafter, neither
party shall directly solicit or recruit any employee or consultant of the other
party for itself or for any other company or individual, without the prior
written consent of the other party. Nothing in the foregoing sentence shall be
construed to prevent either party from hiring an employee of the other party
resulting from (i) advertising of open positions, participating in job fairs or
the like, or other forms of soliciting candidates for employment which are
general in nature or not directed specifically and solely at a given employee of
the other party, (ii) unsolicited inquiries about employment opportunities or
possibilities from headhunters or other agents acting for unidentified
principals, or (iii) unsolicited inquiries about employment opportunities from
any employee.

15.  Force Majeure
     -------------

Neither party hereto shall be responsible for any failure to perform its
obligations under this Agreement (other than obligations under Sections 4 and 5)
if such failure is caused by acts of God, war, strikes, revolutions, lack or
failure of transportation, facilities, laws or governmental regulations or other
causes that are beyond the reasonable control of such party. Obligations
hereunder, however, shall in no event be excused but shall be suspended only
until the cessation of any cause of such failure. In the event that such force
majeure should obstruct performance of this Agreement for more than thirty (30)
calendar days, the parties hereto shall consult with each other to determine
whether this Agreement should be modified or terminated. The party facing an
event of force majeure shall use reasonably commercial efforts to remedy that
situation as well as to minimize its effects. A case of force majeure shall be
notified to the other party by facsimile within five (5) days after its
occurrence and shall be confirmed by a letter.

16.  Entire Agreement
     ----------------

This Agreement constitutes and contains the entire agreement between the parties
with respect to the subject matter hereof and supersedes any prior oral or
written agreements. Each party acknowledges and agrees that the other has not
made any representations, warranties or agreements of any kind, except as
expressly set forth herein.

trade, or course of dealing, except by an instrument in writing signed by duly
authorized employees of both of the parties hereto.

The waiver by either party of a breach of any provision contained herein shall
be in writing and shall in no way be construed as a waiver of any subsequent
breach of such provision or the waiver of the provision itself.

18.  Counterparts
     ------------
This Agreement may be executed in counterparts, including counterpart
transmitted by facsimile, each of which shall be deemed an original, and all
such counterparts shall constitute one and the same agreement.

19.  Survival

20.  Severability

If any provision of this Agreement shall be held illegal or unenforceable, that
provision shall be limited or eliminated to the minimum extent necessary so that
this Agreement shall otherwise remain in full force and effect and enforceable.

21.  Headings
     --------

3.   PREMISES. Landlord hereby leases to Tenant, and Tenant hereby leases from
Landlord, upon the terms and subject to the conditions of this Lease, that
certain space located in the suite and floor of the Building, and containing the
approximate rentable area set forth in Article 2 above (the "Premises") as
further described in Exhibit A attached hereto.

4.   TERM; POSSESSION.  The term of this Lease shall commence on the
Commencement Date and end on the Expiration Date set forth in Article 2 above.
If Landlord, for any reason whatsoever, cannot deliver possession of the
Premises to Tenant at the Commencement Date, this Lease shall not be void or
voidable, nor shall Landlord be liable to Tenant for any loss or damage
resulting therefrom, but in that event no rent shall be payable until the date
on which Landlord delivers possession.

5.   RENT. Tenant agrees to pay to Landlord as rent for the Premises, without
prior notice or demand, offset or deduction, the sum(s) set forth in Paragraph
2(g) above, on the first day of each and every successive calendar month during
the Lease term, except that the first month's rent shall be paid upon the
execution hereof. Rent for any period during the Lease term which is for less
than one (1) month shall be prorated based on a thirty (30) day month. Rent
shall be paid in lawful money of the United States of America to Landlord at the
Office of the Building, or to such other person or at such other place as
Landlord may from time to time designate in writing. All amounts payable or
reimbursable by Tenant to Landlord under this Lease, including amounts payable
as late charges or interest, shall constitute rent and shall be payable and
recoverable as rent in the manner provided in this Lease.

6.   SECURITY DEPOSIT. Tenant has deposited with Landlord the sum set forth in
Paragraph 2(h) above, which shall be held by Landlord as security for the
faithful performance by Tenant of all the terms, covenants and conditions of
this Lease to be kept and performed by Tenant. If Tenant defaults with respect
to any provision of this Lease, including but not limited to the provisions
relating to the payment of rent, Landlord may (but shall not be required to)
use, apply or retain all or any part of this security deposit for the payment of
any rent or for the payment of any amount which Landlord may incur by reason of
Tenant's default. If any portion of such deposit in so used or applied, Tenant
shall, within five (5) days after demand therefor, deposit cash with Landlord in
an amount sufficient to restore the security deposit to its original amount.
Landlord shall not be required to keep this security deposit separate from its
general

                                      1.
<PAGE>

funds, and Tenant shall not be entitled to interest on such deposit. If Tenant
shall fully and faithfully perform every provision of this Lease to be performed
by it, the security deposit or any balance thereof shall be returned to Tenant
(or, at Landlord's option, to the last assignee of Tenant's interest hereunder)
at the expiration of the Lease term. Upon termination of Landlord's interest in
the Building, whether by sale of the Building or otherwise, Landlord shall have
no further obligation to Tenant with respect to the security deposit or any
other sums due hereunder and prepaid by Tenant upon transfer of the security
deposit to Landlord's successor in interest.

7.   USE AND COMPLIANCE WITH LAWS.
       a.   The Premises shall be used for the purposes set forth in Article 2
above and for no other business or purpose.

       b.   Tenant shall not use the Premises or permit anything to be done in
or about the Premises which will in any way conflict with any law, statute,
ordinance or governmental rule or regulation now in force or which may hereafter
be enacted or promulgated (collectively, "Legal Requirements"). Tenant shall, at
its sole cost and expense, promptly comply with all Legal Requirements, and with
the requirements of any board of fire insurance underwriters or other similar
bodies now or hereafter constituted, relating to, or affecting the condition,
use or occupancy of the Premises, excluding structural changes not related to or
affected by Tenant's improvements or acts. The judgment of any court of
competent jurisdiction or the admission of Tenant in any action against Tenant,
whether Landlord be a party thereto or not, that Tenant has violated any Legal
Requirement, shall be conclusive of that fact as between Landlord and Tenant.

       c.   Tenant shall not do or permit anything to be done in or about the
Premises nor bring or keep anything therein which will in any way increase the
existing rate of or affect any fire or other insurance upon the Building or any
of its contents, or cause cancellation of any insurance policy covering the
Building or any part thereof or any of its contents. Tenant shall not do or
permit anything to be done in or about the Premises which will in any way
obstruct or interfere with the rights of other tenants or occupants of the
Building or injure or annoy them, or use or allow the Premises to be used for
any improper, immoral, unlawful or objectionable purpose, nor shall Tenant
cause, maintain or permit any nuisance in, on or about the Premises. Tenant
shall not commit or allow to be committed any waste in or upon the Premises.

       d.   No material or substance that is regulated as a hazardous or toxic
waste, substance, pollutant or contaminant under any Legal Requirement
(collectively, "Hazardous Materials") shall be used, handled, released or
disposed of by Tenant or its employees, agents or representatives (collectively,
"Representatives") or customers, visitors or invitees (collectively, "Visitors")
at or about the Premises or Building without Landlord's prior consent, which
consent may be granted, denied, or conditioned upon compliance with Landlord's
requirements, all in Landlord's absolute discretion. Notwithstanding the
foregoing, normal quantities and use of those Hazardous Materials customarily
used in the conduct of general office activities, such as copier fluids and
cleaning supplies, may be used and stored at the Premises without Landlord's
prior consent. Tenant's activities at or about the Premises and Building with
respect to Hazardous Materials shall comply at all times with all Legal
Requirements. At the expiration or termination of the Lease, Tenant shall
promptly remove from the Premises and Building all Hazardous Materials
introduced by Tenant or its Representatives or Visitors at the Premises or the
Building.

       e.   Tenant shall not make or allow to be made any alterations, additions
or improvements to the Premises or any part thereof. Tenant shall keep the
Premises and the property on which the Premises are situated free from any liens
arising out of any work performed, materials furnished or obligations incurred
by Tenant. If any such lien attaches to the Premises or the Building, and Tenant
does not cause the same to be released by payment, bonding or otherwise within
ten (10) days after the attachment thereof, Landlord shall have the right but
not the obligation to cause the same to be released by such means as it shall
deem proper, and any sums expended Landlord in connection therewith shall be
payable by Tenant on demand.

8.   CONDITION OF PREMISES. By taking possession of the Premises, Tenant shall
be deemed to have accepted the Premises as being in good order, condition and
repair and accepts the Premises in their "as is" condition. During the Lease
term Tenant, at Tenant's sole cost and expense, shall keep the

                                      2.
<PAGE>

Premises and every part thereof, and upon the expiration or sooner termination
of this Lease shall surrender the Premises to Landlord, in good condition and
repair, damage thereto from causes beyond the reasonable control of Tenant and
ordinary wear and tear excepted. Landlord shall have no obligation whatsoever to
alter, remodel, improve, repair, decorate or paint this Premises or any part
thereof. The parties hereto affirm that Landlord has made no representation to
Tenant respecting the condition of the Premises or the Building.

9.   ASSIGNMENT AND SUBLETTING. Tenant shall not either voluntarily or by
operation of law, assign, transfer, mortgage, pledge, hypothecate or encumber
this Lease or any interest therein, and shall not sublet the Premises or any
part thereof, or any right or privilege appurtenant thereto, or allow any other
person (the Representatives and Visitors of Tenant excepted) to occupy or use
the Premises, or any portion thereof.

10.  INDEMNIFICATION OF LANDLORD. Tenant shall indemnify and hold Landlord
harmless from and against any claims, liability, damages, costs or expenses,
including reasonable attorneys' fees and costs incurred in defending against the
same (collectively, "Claims"), arising from (a) the acts or omissions of Tenant
or its Representatives or Visitors in or about the Building, or (b) any
construction or other work undertaken by Tenant on the Premises, or (c) any
breach or default under this Lease by Tenant, or (d) any accident, injury or
damage, howsoever and by whomsoever caused, to any person or property, occurring
in or about the Premises during the Lease term; excepting only such Claims to
the extent they are caused by the gross negligence or willful misconduct of
Landlord or its authorized Representatives. The foregoing indemnity shall
survive the expiration or termination of this Lease.

11.  DAMAGE TO TENANT'S PROPERTY. Tenant hereby assumes all risk of loss, injury
or other damage to any person or property (including, but not limited to, Tenant
or Tenant's Personal Property) in or about the Premises or the Building from any
cause (including, but not limited to: defects in the Building or in any
equipment in the Building, fire, explosion or other casualty; bursting, rupture,
leakage or overflow of any plumbing or other pipes or lines, sprinklers, tanks,
drains, drinking fountains or washstands in, above, or about the Premises or the
Building; or acts of other tenants in the Building), other than from Landlord's
gross negligence or willful misconduct, and Tenant hereby waives all claims in
respect thereof against Landlord. In no event shall Landlord or its
Representatives be liable for any loss or damage to property by theft or
otherwise, for any injury to or damage to property entrusted to employees of the
Building, for interference with the light or other incorporeal hereditaments,
for consequential or punitive damages or loss of business by Tenant, or for any
latent defect in the Premises or in the Building. Tenant shall give prompt
notice to Landlord in case of fire or accidents in the Premises or in the
Building, or of defects therein or in the fixtures or equipment therein.

12.  LIABILITY INSURANCE. Tenant shall, at Tenant's expense, obtain and keep in
force during the Lease term a policy of commercial general liability insurance,
with a comprehensive single limit of not less than $2,000,000, insuring Landlord
and Tenant against any liability arising out of the ownership, use, occupancy or
maintenance of the Premises and all areas appurtenant thereto. The limit of such
insurance shall not, however, limit the liability of Tenant hereunder. If Tenant
fails to procure and maintain such insurance, Landlord may, but shall not be
obligated to, procure and maintain the same at the expense of Tenant. Prior to
occupancy of the Premises, Tenant shall deliver to Landlord copies of policies
of the insurance required herein or certificates evidencing the existence and
amount of such insurance with loss payable clauses satisfactory to Landlord. No
policy shall be cancelable or subject to reduction of coverage except after
thirty (30) days' prior notice to Landlord.

13.  MUTUAL WAIVER. To the extent permitted by their respective policies of
insurance, Landlord and Tenant each hereby waive any right of recovery against
the other and the authorized Representatives of the other for any loss or damage
that is covered by any policy of insurance maintained by either party with
respect to the Premises or the Building or any operation therein. If any policy
of insurance relating to this Lease or to the Premises or the Building does not
permit the foregoing waiver or if the coverage under any such policy would be
invalidated as a result of such waiver, the party maintaining such policy shall,
if

                                      3.
<PAGE>

possible, obtain from the insurer under such policy a waiver of all right of
recovery by way of subrogation against either party in connection with any
claim, loss or damage covered by such policy. If either party is not able to
obtain such waiver, then such party shall have the other party named as an
additional insured on all such policies of insurance.

14.  SERVICES AND UTILITIES.

       a.   Landlord agrees to furnish to the Premises, during Business Hours on
Business Days as set forth in Paragraph 2(k) above, and subject to the rules and
regulations of the Building, "Building Standard" amounts of electricity, heat
and janitorial service.  Upon request by Tenant in accordance with the
procedures established by Landlord from time to time for furnishing HVAC Service
at times other than Business Hours on Business Days, Landlord shall furnish such
service to Tenant and Tenant shall pay for such services on an hourly basis at
the then prevailing rate established for the Building by Landlord.  As of the
date of this Lease, the prevailing rate for furnishing HVAC Service at times
other than Business Hours on Business Days is $25.00 per hour per floor which
may be changed from time to time in Landlord's sole discretion.  Landlord shall
also maintain and keep lighted the common stairs, common entries and toilet
rooms in the Building.  No interruption, failure or inability to provide any
service or utility, regardless of its duration, shall constitute an eviction of
Tenant, constructive or otherwise, or impose upon Landlord any liability
whatsoever, including, but not limited to, liability for consequential damages
or loss of business by Tenant, or entitle Tenant to an abatement of rent.

       b.   Tenant shall not use any apparatus or device in the Premises which
will in any way increase the amount of electricity usually furnished or supplied
for the use of the Premises as general office space, nor connect with electric
current any apparatus or device except through existing electrical outlets in
the Premises. If Tenant's usage of electricity, water or any other utility
exceeds the Building Standard use of such utility, then to the extent permitted
by Legal Requirements, Landlord may determine the amount of such excess use by
any reasonable means (including, but not limited to, the installation at
Landlord's request but at Tenant's expense of a separate meter or other
measuring device) and charge Tenant for the cost thereof.

15.  CASUALTY. If the Premises shall be partially or totally destroyed by fire
or other casualty, this Lease shall terminate effective upon the date of such
casualty.

16.  TENANT'S TAXES. Tenant shall pay, or cause to be paid, before delinquency,
any and all taxes levied or assessed and which become payable during the Lease
term upon all of Tenant's equipment, furniture, fixtures and personal property
located in the Premises (collectively, "Tenant Property"). If any or all of
Tenant's Property shall be assessed and taxed with the Building, Tenant shall
pay to Landlord its share of such taxes within ten (10) days after delivery to
Tenant by Landlord of a statement in writing setting forth the amount of such
taxes applicable to Tenant's property.

17.  RULES AND REGULATIONS. Tenant shall comply with the rules and regulations
that Landlord shall from time to time promulgate with respect to the Building.
Landlord reserves the right from time to time to make all reasonable
modifications to such rules, which shall be binding upon Tenant upon delivery of
a copy to Tenant. Landlord shall not be liable to Tenant for the nonperformance
of any rules or regulations by any other tenants or occupants. A copy of
Building Rules is attached hereto as Exhibit C.

18.  HOLDING OVER. If Tenant remains in possession of the Premises or any part
thereof after the expiration or termination of this Lease, such possession shall
be on the basis of a tenancy at the sufferance of Landlord, and Tenant shall
continue to comply with or perform all the terms and obligations of Tenant under
this Lease, except that the rent during Tenant's holding over shall be twice the
rent payable in the last month prior to such expiration or termination.

19.  ENTRY BY LANDLORD. Landlord reserves and shall at any and all times have
the right to enter the Premises, inspect the same, and supply janitorial service
and any other service to be provided by Landlord to Tenant hereunder, to show
the Premises to prospective purchasers or tenants, and to alter, improve or
repair the Premises and any portion of the Building that Landlord may deem
necessary or

                                      4.
<PAGE>

desirable, and may for that purpose erect scaffolding and other necessary
structures where reasonably required by the character of the work to be
performed; provided, however, that the entrance to the Premises shall not be
blocked thereby, and provided further that Landlord shall use reasonable efforts
to avoid any unreasonable interference with the business of Tenant. Landlord
shall at all times have a key with which to unlock all of the doors in, upon and
about the Premises (excluding Tenant's vaults, safes and files), for the
foregoing purposes. In addition, Landlord shall have the right, without
liability to Tenant, to use any and all means which Landlord may deem proper to
open such doors in an emergency, in order to obtain entry to the Premises. Any
entry to the Premises obtained by Landlord by any of such means or otherwise
shall not under any circumstances be construed or deemed to be a forcible of
unlawful entry into, or a detainer of, the Premises, or an eviction from the
Premises or any portion thereof, and Tenant hereby waives any claim for damages
or for any injury or inconvenience to or interference with Tenant's business,
any loss of occupancy or quiet enjoyment of the Premises, and any other loss
occasioned thereby.

20.  DEFAULT. The occurrence of any one or more of the following events shall
constitute an "Event of Default" under this Lease by Tenant:

       a.   The failure by Tenant to make any payment of rent within five (5)
days of its due date.

       b.   The failure by Tenant to observe or perform any of the covenants,
conditions or provisions of this Lease to be observed or performed by Tenant,
where such failure continues for a period of ten (10) days after notice thereof
by Landlord to Tenant.

       c.   The making by Tenant of any general assignment or general
arrangement for the benefit of creditors; or the filing by or against Tenant of
a petition to have Tenant adjudged bankrupt, or a petition or reorganization or
arrangement under any law relating to bankruptcy (unless, in the case of a
petition filed against Tenant, the same is dismissed within sixty (60) days); or
the appointment of a trustee or a receiver to take possession of substantially
all of Tenant's assets located at the Premises or of Tenant's interest in this
Lease, where possession is not restored to Tenant within thirty (30) days; or
the attachment, execution or other judicial seizure of substantially all of
Tenant's assets located at the Premises or of Tenant's interest in this Lease,
where such seizure is not discharged in thirty (30) days.

       Upon the occurrence of an Event of Default Landlord shall have and may
pursue any and all remedies now or hereafter available to Landlord under law,
including without limitation the right to recover from Tenant all damages
incurred by Landlord by reason of Tenant's default, including but not limited to
the cost of recovering possession of the Premises and reasonable attorneys'
fees.

21.  AUTHORITY.  If Tenant is a corporation or a partnership, each of the
persons executing this Lease on behalf of Tenant warrants and represents that
Tenant is a duly authorized and validly existing entity, that Tenant has full
right and authority to enter into this Lease and that the persons signing on
behalf of Tenant are authorized to do so and have the power to bind Tenant to
this Lease.  Upon request by Landlord, Tenant shall provide Landlord with
evidence reasonably satisfactory to Landlord confirming the foregoing
representations.

22.  GENERAL PROVISIONS.

       a.   Waiver. The waiver by Landlord of any term, covenant or condition
herein contained shall not be deemed to be a waiver of such term, covenant or
condition on any subsequent breach of the same or any other term, covenant or
condition herein contained. The subsequent acceptance of rent hereunder by
Landlord shall not be deemed to be a waiver of any preceding breach by Tenant of
any term, covenant or condition of this Lease, other than the failure of Tenant
to pay the particular rent so accepted, regardless of Landlord's knowledge of
such preceding breach at the time of the acceptance of such rent.

       b.   Notices. Any notice, demand, request, consent, approval or
communication to be given by either party to the other hereunder must be in
writing and shall be sent by United States mail, postage prepaid, and if to
Tenant shall be addressed to Tenant at the Premises, or to such other place as
Tenant may from time to time designate in a notice to Landlord, and if to
Landlord, shall be addressed to Landlord at the Office of the Building, or to
such other person or place as Landlord may from time to time designate in a
notice to Tenant.

                                      5.
<PAGE>

       c.   Joint Obligation. If Tenant consists of more than one entity, the
obligations hereunder imposed upon Tenant shall be joint and several.

       d.   Headings. The headings and article titles contained in this Lease
are for purposes of convenience only and are not to be used to interpret or
construe this Lease.

       e.   Time.  Time is of the essence of this Lease and each and all of its
provisions.

       f.   Successors and Assigns. The covenants and conditions herein
contained, subject to the provisions of Article 9 (Assignment and Subletting)
and Paragraph 22(m) (Landlord's Liability), shall inure to the benefit of and be
binding upon the heirs, successors, executors, administrators and assigns of the
parties hereto.

       g.   Recordation.  Neither Landlord nor Tenant shall record this Lease.

       h.   Quiet Possession. Upon Tenant paying the rent reserved hereunder and
observing and performing all of the covenants, conditions and provisions as
Tenant's part to be observed and performed hereunder, Tenant shall have quiet
possession of the Premises for the entire term hereof, subject to all the
provisions of this Lease.

       i.   Late Charges and Interest. Tenant hereby acknowledges that late
payment by Tenant to Landlord of rent will cause Landlord 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 upon Landlord by
terms of any mortgages or trust deed covering the Premises. Accordingly, if any
installment of rent is not received by Landlord within ten (10) days after
notice that such amount is past due, then Tenant shall pay to Landlord a late
charge equal to ten percent (10%) of such overdue amount. The parties hereby
agree that such late charge represents a fair and reasonable estimate of the
cost that Landlord will incur by such reason of the late payment by Tenant.
Acceptance of any late charge by Landlord shall in no event constitute a waiver
of Tenant's default with respect to such overdue amount, nor prevent Landlord
from exercising any of the other rights and remedies granted hereunder. In
addition to the late charges referred to above, which are intended to defray
Landlord's costs resulting from late payments, any late payment of rent shall,
at Landlord's option, bear interest from the due date of any such payment to the
date same is paid at a rate of eighteen percent (18%) per annum or the maximum
lawful rate that Landlord may charge to Tenant under applicable laws, whichever
is less (the "Interest Rate").

       j.   Entire Agreement. This Lease, including any exhibits or addenda
attached hereto or documents referred to herein, constitutes the entire
agreement between Landlord and Tenant with respect to the leasing of space by
Tenant in the Building, and supersedes all prior or contemporaneous agreements,
understandings, proposals and other representations by or between Landlord and
Tenant, whether written or oral. Neither Landlord nor Landlord's agents have
made any representations or warranties with respect to the Premises, the
Building or this Lease except as expressly set forth herein, and no rights,
easements or licenses shall be acquired by Tenant by implication or otherwise
unless expressly set forth herein. The submission of this Lease for examination
does not constitute an option for the Premises and this Lease shall become
effective as a binding agreement only upon execution and delivery thereof by
Landlord to Tenant. No provision of this Lease may be amended or added to except
by an agreement in writing signed by the parties hereto.

       k.   Inability to Perform. This Lease and the obligations of Tenant
hereunder shall not be affected or impaired because Landlord is unable to
fulfill any of its obligations hereunder or is delayed in doing so, if such
inability or delay is caused by reason of strike, labor troubles, act of God, or
any other cause beyond the reasonable control of Landlord.

       l.   Attorney's Fees. If Tenant or Landlord brings any action for the
enforcement or interpretation of this Lease, including any suit by Landlord for
the recovery of rent or possession of the Premises, the losing party shall pay
to the prevailing party a reasonable sum for attorneys' fees. The "prevailing
party" will be determined by the court before whom the action was brought based
upon an assessment of which party's major arguments or positions taken in the
suit or proceeding could fairly be said to have prevailed over the other party's
major arguments or positions on major disputed issues in the court's decision.
Any attorneys' fees and other costs and expenses incurred by either party in
enforcing a judgment in its favor under this Lease shall be recoverable
separately from and in addition to any other amount included in such judgment,
and such attorneys' fees obligation is intended to be severable from the other
provisions hereof and to survive and not be merged in any such judgment.

                                      6.
<PAGE>

       m.   Landlord's Liability. The term "Landlord," as used in this Lease,
shall mean only the owner or owners of the Building at the time in question.
Notwithstanding any other term or provision of this Lease, the liability of
Landlord for its obligations under this Lease is limited solely to Landlord's
interest in the Building as the same may from time to time be encumbered, and no
personal liability shall at any time be asserted or enforceable against any
other assets of Landlord or against Landlord's partners or their stockholders,
directors, officers or partners on account of any of Landlord's obligations or
actions under this Lease. In addition, in the event of any conveyance of title
to the Building, then from and after the date of such conveyance, Landlord shall
be relieved of all liability with respect to Landlord's obligations to be
performed under this Lease after the date of such conveyance. Upon any
conveyance of title to the Building or the Building, the grantee or transferee,
by accepting such conveyance, shall be deemed to have assumed Landlord's
obligations to be performed under this Lease from and after the date of
transfer, subject to the limitations on liability set forth above in this
paragraph.

       n.   Subordination, Attornment.  This Lease is expressly made subject and
subordinate to any present or future mortgage, deed of trust, ground lease,
underlying lease or like encumbrance affecting any part of the Building or any
interest of Landlord therein which is now existing or hereafter executed or
recorded ("Encumbrance").  If the interest of Landlord in the Building is
transferred to any person ("Purchaser") pursuant to or in lieu of proceedings
for enforcement of any Encumbrance, Tenant shall immediately and automatically
attorn to the Purchaser, and this Lease shall continue in full force and effect
as a direct lease between the Purchaser and Tenant on the terms and conditions
set forth in this Lease.

       o.   Separability.  Any provision of this Lease which shall prove to be
invalid, void or illegal shall in no way affect, impair or invalidate any other
provision hereof and such other provisions shall remain in full force and
effect.

       p.   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.

       q.   Choice of Law. This Lease shall be governed by the laws of the State
of California.

23.    BROKERS. Tenant warrants that it has had no dealings with any real estate
broker or agents in connection with the negotiation of this Lease and it knows
of no other real estate broker or agent who is entitled to a commission in
connection with this Lease. Tenant agrees to indemnify and hold Landlord
harmless from any claims incurred by Landlord asserted by any other broker or
finder for a fee or commission based upon any dealings with or statements made
by Tenant or its Representatives.

       IN WITNESS WHEREOF, the parties hereto have entered into this Lease as of
the date first written above.

                          ADDITIONAL PROVISIONS RIDER
                          ---------------------------

PARKING.

     a.   Tenant's Parking Rights. Landlord shall provide Tenant, on an
          -----------------------
unassigned and non-exclusive basis, for use by Tenant and Tenant's
Representatives and Visitors, at the users' sole risk, three (3) parking spaces
in the Parking Facility. The parking spaces to be made available to Tenant
hereunder may contain a reasonable mix of spaces for compact cars and up to ten
percent (10%) of the unassigned spaces may also be designated by Landlord as
Building visitors' parking.

     b.   Availability of Parking Spaces. Landlord shall take reasonable actions
          ------------------------------
to ensure the availability of the parking spaces leased by Tenant, but Landlord
does not guarantee the availability of those spaces at all times against the
actions of other tenants of the Building and users of the Parking Facility.
Access to the Parking Facility may, at Landlord's option, be regulated by card,
pass, bumper sticker, decal or other appropriate identification issued by
Landlord. Landlord retains the right to revoke the parking privileges of any
user of the Parking Facility who violates the rules and regulations governing
use of the Parking Facility (and Tenant shall be responsible for causing any
employee of Tenant or other person using parking spaces allocated to Tenant to
comply with all parking rules and regulations).

     c.   Monthly Parking Rental.  Tenant shall pay to Landlord, as monthly rent
          ----------------------
for the parking spaces leased by Tenant hereunder, a "Monthly Parking Rental"
per space, which shall be the "Prevailing Parking Rental" for such parking
spaces in effect from time to time.  As of the date of this Lease, the
Prevailing Parking Rental is $90.00 per parking space per month.  The Prevailing
Parking Rental shall be determined by Landlord, based on the monthly rental
charged by Landlord from time to time for spaces in the Parking Facility, the
unassigned or reserved nature of such parking spaces, and the fair market rental
charged for comparable parking facilities in comparable buildings in the
vicinity of the Property.  Tenant's Monthly Parking Rental shall be paid on the
first day of each month during the Term of this Lease; provided, however, that
in the event Tenant fails to pay Tenant's Monthly Parking Rental when due,
Landlord may assess a late charge of $50.00 on the delinquent amount, and
provided further that in the event Tenant fails to pay Tenant's Monthly Parking
Rental within thirty (30) days of Landlord's notice of such delinquency,
Landlord shall have the right by notice to Tenant permanently to terminate
Tenant's rights to use parking spaces hereunder, whether or not Landlord
declares a default under the Lease.

     d.   Assignment and Subletting.  Notwithstanding any other provision of the
          -------------------------
Lease to the contrary, Tenant shall not assign its rights to the parking spaces
or any interest therein, or sublease or otherwise allow the use of all or any
part of the parking spaces to or by any other person, except with Landlord's
prior written consent, which may be granted or withheld by Landlord in its sole
discretion. In the event of any separate assignment or sublease of parking space
rights that is approved by Landlord, Landlord shall be entitled to receive, as
additional Rent hereunder, one hundred percent (100%) of any profit received by
Tenant in connection with such assignment or sublease.

                               Exhibit B, Page 1
<PAGE>


     e.   Condemnation, Damage or Destruction. In the event the Parking Facility
          -----------------------------------
is the subject of a Condemnation, or is damaged or destroyed, and this Lease is
not terminated, and if in such event the available number of parking spaces in
the Parking Facility is permanently reduced, then Tenant's rights to use parking
spaces hereunder may, at the election of Landlord, thereafter be reduced in
proportion to the reduction of the total number of parking spaces in the Parking
Facility, and the Monthly Parking Rental payable hereunder shall be reduced
proportionately. In such event, Landlord reserves the right to reduce the number
of parking spaces to which Tenant is entitled or to relocate some or all of the
parking spaces to which Tenant is entitled to other areas in the Parking
Facility.

                                 BUILDING RULES
                                 --------------

     The following Building Rules are additional provisions of the foregoing
Lease to which they are attached.  The capitalized terms used herein have the
same meanings as these terms are given in the Lease.

     1.   Use of Common Areas.  Tenant will not obstruct the sidewalks, halls,
          -------------------
passages, exists, entrances, elevators or stairways of the Building ("Common
Areas"), and Tenant will not use the Common Areas for any purpose other than
ingress and egress to and from the Premises.  The Common Areas, except for the
sidewalks, are not open to the general public and Landlord reserves the right to
control and prevent access to the Common Areas of any person whose presence, in
Landlord's opinion, would be prejudicial to the safety, reputation and interests
of the Building and its tenants.

     2.   No Access to Roof.  Tenant has no right of access to the roof of the
          -----------------
Building and will not install, repair or replace any antenna, aerial, aerial
wires, fan, air-conditioner or other device on the roof of the Building, without
the prior written consent of Landlord.  Any such device installed without such
written consent is subject to removal at Tenant's expense without notice at any
time.  In any event Tenant will be liable for any damages or repairs incurred or
required as a result of its installation, use, repair, maintenance or removal of
such devices on the roof and agrees to indemnify and hold harmless Landlord from
any liability, loss, damage, cost or expense, including reasonable attorneys'
fees, arising from any activities of Tenant or of Tenant's Representatives on
the roof of the Building.

     3.   Signage.  No sign, placard, picture, name, advertisement or notice
          -------
visible from the exterior of the Premises will be inscribed, painted, affixed or
otherwise displayed by Tenant on or in any part of the Building without the
prior written consent of Landlord.  Landlord reserves the right to adopt and
furnish Tenant with general guidelines relating to signs in or on the Building.
All approved signage will be inscribed, painted or affixed at Tenant's expense
by a person approved by Landlord, which approval will not be unreasonably
withheld.

     4.   Prohibited Uses.  The Premises will not be used for manufacturing, for
          ---------------
the storage of merchandise held for sale to the general public, for lodging or
for the sale of goods to the general public.  Tenant will not permit any food
preparation on the Premises except that Tenant may use Underwriters' Laboratory
approved equipment for brewing coffee, tea, hot chocolate and similar beverages
so long as such use is in accordance with all applicable federal, state and city
laws, codes, ordinances, rules and regulations.

     5.   Janitorial Services.  Tenant will not employ any person for the
          -------------------
purpose of cleaning the Premises or permit any person to enter the Building for
such purpose other than Landlord's janitorial service, except with Landlord's
prior written consent.  Tenant will not necessitate, and will be liable for the
cost of, any undue amount of janitorial labor by reason of Tenant's carelessness
in or indifference to the preservation of good order and cleanliness in the
Premises.  Janitorial service will not be furnished to areas in the Premises on
nights when such areas are occupied after 9:30 p.m., unless such service is
extended by written agreement to a later hour in specifically designated areas
of the Premises.

                               Exhibit C, Page 1
<PAGE>

     6.   Keys and Locks.  Landlord will furnish Tenant, free of charge, two
          --------------
keys to each door or lock in the Premises.  Landlord may make a reasonable
charge for any additional or replacement keys.  Tenant will not duplicate any
keys, alter any locks or install any new or additional lock or bolt on any door
of its Premises or on any other part of the Building without the prior written
consent of Landlord and, in any event, Tenant will provide Landlord with a key
for any such lock.  On the termination of the Lease, Tenant will deliver to
Landlord all keys to any locks or doors in the Building which have been obtained
by Tenant.

     7.   Freight.  Upon not less than twenty-four hours prior notice to
          -------
Landlord, which notice may be oral, an elevator will be made available for
Tenant's use for transportation of freight, subject to such scheduling as
Landlord in its discretion deems appropriate.  Tenant shall not transport
freight in loads exceeding the weight limitations of such elevator.  Landlord
reserves the right to prescribe the weight, size and position of all equipment,
materials, furniture or other property brought into the Building, and no
property will be received in the Building or carried up or down the freight
elevator or stairs except during such hours and along such routes and by such

in a manner consistent with Landlord's directional signs and markings in the

not be construed to in any way modify or amend, in whole or in part, the terms,

                              SUBLEASE AGREEMENT

  THIS SUBLEASE AGREEMENT (this "Sublease") is made and entered into this 23rd
  day of February, 2000, by and between Attachmate Corporation, a Washington
  corporation ("Attachmate") and Mercata, Inc., a Delaware corporation,
  ("Mercata").

  WHEREAS, by that certain Office Building Lease, dated April 29, 1998 and the
  First Amendment to Four Newport Office Building Lease, dated July 28, 1999,
  (collectively known as the "Master Lease"), attached hereto as Exhibit A and
                                                                 ----------
  incorporated by reference herein, Attachmate leased from Bentall Newport
  Centre L.L.C., ("Bentall") certain premises consisting of approximately One
  Hundred Fifty Three Thousand Four Hundred Three (153,403) square feet (the
  "Premises") in the Four Newport Building located in Bellevue, Washington (the
  "Building"); and

  WHEREAS, Attachmate has agreed to sublease a portion of the Premises,
  consisting of the approximately Twenty Six Thousand Four Hundred Sixty
  (26,460) square feet on the sixth (6th) floor of the Building as depicted on
  Exhibit B attached hereto and made a part hereof (the "Subleased Premises") to
  ----------
  Mercata on the terms and conditions hereinafter set forth;

  NOW THEREFORE, in consideration of the rents, covenants, agreements,
  stipulations and provisions contained herein to be paid, kept and performed by
  both Mercata and Attachmate, the parties do hereby agree as follows:

1.  LEASE DATA AND EXHIBITS:
    -----------------------

1.1  Land, Building and Subleased Premises. "Newport Corporate Center" as used
     -------------------------------------
     in this Sublease means all of the buildings, grounds, streets, parking
     areas and other improvements comprising the Newport Corporate Center as
     described in the Master Lease. "Land" as used in this Sublease shall mean
     the real property legally described on "Exhibit A" of the Master Lease.
     "Building" as used in this Sublease means Four Newport Building comprised
     of approximately 153,403 rentable square feet and shown on Exhibits A-2
     through A-7 of the Master Lease. "Subleased Premises" as used in this
     Sublease means that space consisting of approximately 26,460 square feet of
     rentable area on the sixth (6th) floor of the Building, as outlined on the
     floor plan attached hereto as Exhibit B of this Sublease, including the
                                   ---------
     applicable Tenant Improvements described in "Exhibit C" of the Master
     Lease. As the precise number of rentable square feet in the Subleased
     Premises cannot be determined as of the date of this Sublease, the rentable
     square feet of the Subleased Premises shall be calculated by Attachmate
     within thirty (30) days after the Commencement Date of this Sublease based
     on Bentall's final determination of the square footage of the Premises as
     set forth in Section 1.3 of the Master Lease. Attachmate shall thereafter
     notify Mercata of any necessary adjustments due to such final measurement.

1.2  Term. The term of this Sublease shall be for twenty-four (24) months and
     ----
     fourteen (14) days (the "Term"). Mercata hereby acknowledges that the
     Master Lease commences upon Substantial Completion of the Building Shell,
     parking, common areas and Tenant Improvements, as such term is defined
     under Section 1.4 of the Master Lease. Attachmate hereby subleases the
     Subleased Premises to Mercata and Mercata hereby subleases the Subleased
     Premises from Attachmate commencing as of the date of Substantial
     Completion of the Subleased Premises (the "Commencement Date"). The Master
     Lease contemplates that the date of Substantial Completion of the Subleased
     Premises will be March 8, 2000 (the "Estimated Commencement Date"), but
     such date may be extended as provided in the Master Lease. In the event the
     Commencement Date does not occur on or before June 8, 2000, Mercata shall
     have the right to terminate this Sublease by giving written notice to
     Attachmate of such termination at any time between June 9, 2000 and July 1,
     2000 or

                                       1
<PAGE>

     Mercata's right to so terminate shall lapse and be of no further force and
     effect. Attachmate shall provide written notice to Mercata of any
     anticipated or actual delay in the Estimated Commencement Date within three
     (3) business days of learning of such delay. Mercata hereby acknowledges
     that under certain conditions the Master Lease may be terminated pursuant
     to Section 2 of the Master Lease, and that if the Master Lease is so
     terminated this Sublease shall be terminated after written notice of such
     termination to Mercata, and Attachmate shall have no further obligation to
     Mercata. If this Sublease is so terminated, all deposits, Rent and other
     payments paid in advance by Mercata shall be immediately refunded to
     Mercata.

1.3  Option to Extend. Attachmate hereby grants to Mercata the right, privilege
     ----------------
     and option to extend the Term of this Sublease for one (1) period of one
     (1) year ("First Extended Term") from the date of expiration of the initial
     Term, upon the same terms and conditions as herein contained, except as
     indicated below in Section 3. Mercata will be given the option to extend
     for the additional one year in the event Attachmate does not intend to
     occupy the Subleased Premises at the end of the initial Term. Attachmate
     shall provide Mercata with six (6) months prior written notice of its
     intention to occupy or not. If Attachmate does not intend to occupy,
     Mercata shall exercise the option to extend by providing Attachmate with a
     minimum of four (4) months written notice and evidence of the renewal of
     the Letter of Credit for the duration of the First Extended Term as
     required in Section 4 below.

2.  USE:
    ---

2.1  The Subleased Premises shall be used for Mercata's office and related uses,
     and for no other use whatsoever. Mercata shall comply as to the Subleased
     Premises with all requirements under the Master Lease as to the Premises,
     including, without limitation, Article 7. Provided Mercata complies with
     all of the terms of this Sublease, including the payment of Rent, Mercata
     shall have the right to leave the Subleased Premises unoccupied. Mercata
     acknowledges that neither Bentall nor Attachmate nor any agent acting on
     their behalf has made any representation or warranty with respect to the
     suitability of the Subleased Premises for the conduct of Mercata's
     business.

2.2  Normal building hours are from 7 a.m. to 6 p.m. weekdays and 7 a.m. to 1
     p.m. on Saturdays, except for holidays. Access to the building shall be 24
     hours per day, 365 days per year for Mercata employees with key cards.
     Mercata shall be entitled to all utilities and services provided to
     Attachmate under the Master Lease.  Mercata will be billed by Attachmate
     according to actual usage of after hours HVAC at the rate provided in
     Section 6(b) of the Master Lease.  Mercata shall be entitled to the same
     and as frequent of janitorial and maintenance services to the Subleased
     Premises as Attachmate is allowed under the Master Lease, including
     janitorial service five (5) days per week.

3.   RENT: Beginning on a date fourteen (14) days after the Commencement Date
     ----
     (the "Rent Commencement Date"), Mercata covenants and agrees to pay to
     Attachmate, without deduction or set off, base rental for the Term (the
     "Base Rent") in monthly installments at the annual rate of $21.00 per
     rentable square foot. It is estimated, based on the estimated number of
     rentable square feet, that the monthly installment of Base Rent shall be
     $46,305.00 per month for each month of the Term. Notwithstanding the
     foregoing, Mercata shall be entitled to any abatement of Rent as set forth
     in this Sublease or that Attachmate is entitled to with respect to the
     Subleased Premises under the Master Lease. Attachmate shall confirm the
     exact amount of Base Rent in the Notice, attached hereto as Exhibit C,
                                                                 ---------
     within thirty (30) days after the Commencement Date based on its final
     determination of the number of rentable square feet in the Subleased
     Premises. Should Mercata exercise its option to extend the term of the
     Sublease by the additional one year, the Base Rent will be an annual rate
     of $22.00 per rentable square foot.

4.   SECURITY DEPOSIT: Within fourteen (14) days after the execution and
     ----------------
     delivery of this Sublease, Mercata shall deliver to Attachmate an
     irrevocable and unconditional standby Letter of Credit (herein, together
     with all replacements thereof, being called the "Letter of Credit") issued
     by U.S. Bank of Washington, National Association, Bank of America, or
     another bank or financial institution reasonably acceptable to Attachmate.
     The Letter of Credit shall secure Mercata's payment obligations under the
     Sublease and shall be in an

                                       2
<PAGE>

     amount equal to $200,000. The term of the Letter of Credit shall extend
     from the Commencement Date of the Sublease to the earlier of (i) ninety
     (90) days after the expiration of the Term (including any extensions
     thereof) or earlier termination of this Sublease; or (ii) in the event
     Mercata is not in default under this Sublease, the day after Mercata has
     fully surrendered the Subleased Premises to Attachmate in the manner
     required under Section 9 below. Further, the Letter of Credit shall contain
     an evergreen renewal provision with not less than 90 days notice to
     Attachmate on nonrenewal), provided, however, Mercata's notice exercising
     it's option to extend the Term shall contain evidence of renewal of the
     Letter of Credit for the First Extended Term.

     The Letter of Credit shall be in a form reasonably acceptable to
     Attachmate, shall be irrevocable, multiple draw, and subject only to the
     condition that a proper draw certificate or claim be presented and to no
     other condition. The Letter of Credit shall be transferable and assignable
     by Attachmate, in whole or in part without cost to Attachmate, upon a
     transfer of all of Attachmate's interest in the Premises. Mercata shall pay
     all reasonable costs and shall take all reasonable steps necessary for any
     such proposed transfer or assignment of the Letter of Credit. If Mercata
     shall fail to pay such costs or take such steps in connection with a
     proposed transfer or assignment of the Letter of Credit, then Attachmate
     may, after written notice to Mercata as required under Section 18 below,
     draw upon the Letter of Credit in whole or in part and may transfer the
     proceeds of such draw. The Letter of Credit may be drawn in whole or in
     part by Attachmate from time to time (and more than one time for partial
     draws) upon the occurrence of any event of default by Mercata under the
     Sublease, after notice and the expiration of any applicable cure period,
     and without further notice to Mercata. Attachmate may draw upon the Letter
     of Credit without proceeding against any person or exhausting any other
     remedies that Attachmate may have and without resorting to any other
     security held by Attachmate. Attachmate may apply the proceeds of the
     Letter of Credit in any order or manner to any amounts owed by Mercata
     under or pursuant to this Sublease. In the event of a draw by Attachmate
     upon the Letter of Credit as provided for herein, Mercata shall be required
     to replace the amount of the draw by a like amount to the Letter of Credit
     so the balance of the Letter of Credit remains $200,000. Such application
     shall not cure an event of default by Mercata under this Sublease until
     such time as Mercata has reinstated the drawn amount of the Letter of
     Credit in full. Furthermore, in no event shall the Letter of Credit, or
     Attachmate's right to draw upon the Letter of Credit, be affected or
     impaired by (i) the waiver, compromise, settlement, termination or other
     release of the performance or observance by any person liable or to become
     liable for the obligations under this Sublease; (ii) the modification or
     amendment (whether material or otherwise) of any obligation, covenant or
     agreement set forth in this Sublease; (iii) the voluntary or involuntary
     liquidation, dissolution, sale of all or substantially all of the assets,
     marshalling of assets and liabilities, receivership, conservatorship,
     insolvency, bankruptcy, assignment for the benefit of creditors,
     reorganization, arrangement, composition or readjustment of, or any similar
     proceeding affecting Mercata, or any allegation or contest of the validity
     of this Sublease; or (iv) the taking or the omission of any of the actions
     referred to in this Sublease.

5.   TIME AND PLACE OF PAYMENT: As used herein, the term "Rent" shall include
     -------------------------
     Base Rent, Additional Rent, and any other payment obligations of Mercata
     under this Sublease. Rent shall be due on the first day of each calendar
     month after the Rent Commencement Date provided for herein. If the Rent
     Commencement Date occurs on a day other than the first (1st) day of the
     month, the Rent for such partial month shall be prorated based on a 365-day
     year and shall be paid on the Rent Commencement Date of this Sublease. In
     the event any payment of Rent is not paid within five (5) days following
     the due date, Mercata shall pay to Attachmate upon demand a late charge
     equal to 5% of the amount overdue. All payments of Rent shall be made
     payable to the order of "Attachmate Corporation" and addressed to
     Attachmate Corporation, P.O. Box 90026, Bellevue, WA., 98009-9026 ATTN:

     Base Rent, and each month thereafter for the balance of the Term, and any
     extended Term, Mercata shall pay to Attachmate Additional Rent applicable
     to the Subleased Premises as defined in the Master Lease at Section 4. It
     is estimated that Mercata's pro rata share of building operating costs and
     real estate taxes shall be 17.25%

                                       3
<PAGE>

     and Mercata's share of operating costs attributable to the Newport
     Corporate Centre Common Areas shall be 3.92%. Attachmate shall confirm the
     exact amount of Tenant's Percentage in the Notice, attached hereto as
     Exhibit C, within thirty (30) days after the Commencement Date. All such
     ---------
     payments shall be made on or prior to the date Attachmate is required under
     the Master Lease to make payments of Additional Rent. Attachmate shall
     furnish to Mercata no later than ten (10) days after receipt; a copy of all
     accountings of Operating Expenses (as defined in the Master Lease)
     furnished pursuant to the Master Lease.

     -------------------------------------------
     Premises or any part thereof are, at any time prior to or during the Term
     of this Sublease, damaged by fire or other casualty, this Sublease shall
     remain in full force and effect unless and until the Master Lease is
     canceled; provided that if more than fifty percent (50%) of the rentable
     square feet of the Subleased Premises is damaged by fire or other casualty
     on or before the Commencement Date, Mercata shall have the right to
     terminate this Sublease upon fifteen (15) days' prior written notice to
     Attachmate. If the Master Lease is canceled for such cause, Mercata's
     obligations hereunder shall abate as of the effective date thereof.
     Otherwise, such obligations shall abate only to the actual monetary extent
     and for the duration that Attachmate's obligations are reduced in
     accordance with the terms of the Master Lease.

8.   RIGHT OF ENTRY: During the initial construction period Mercata shall be
     --------------
     provided reasonable access to the Subleased Premises for the purpose of
     inspecting the Subleased Premises, in the manner and under the same terms
     and condition such inspection is available to Attachmate under the Master
     Lease. After the Commencement Date, Attachmate, and it's employees, and
     contractors shall have the right to enter the Subleased Premises upon
     twenty-four (24) hour's prior written notice to Mercata; provided that
     Mercata shall have the right to require Attachmate and it's employees and

     Property, as defined in the Master Lease. Mercata and Attachmate shall meet
     prior to such date to work out a reasonable and mutually acceptable
     schedule for such installation, including, but not limited to the use of
     the freight elevator.

9.   ACCEPTANCE AND SURRENDER OF SUBLEASED PREMISES: Mercata acknowledges and
     ----------------------------------------------
     agrees that the Subleased Premises will be constructed and improved as
     outlined in "Exhibit C" of the Master Lease. Mercata agrees to accept the
     Subleased Premises when it is Substantially Complete, as determined by
     Attachmate and Bentall pursuant to the Master Lease. Any further
     improvements to the Subleased Premises desired by Mercata shall be
     submitted to Bentall and Attachmate in the manner required under Section
     25A of the Master Lease, except that Mercata shall not be excluded from
     seeking approval from Attachmate (but shall be excluded from seeking
     approval from Bentall) for improvements which cost less than Ten Thousand
     and No/100 Dollars ($10,000.00). Attachmate shall not unreasonably
     withhold, condition or delay its approval of such further improvements.
     Mercata acknowledges that if approval is given, a condition of such
     approval shall be a requirement that Mercata restore the Subleased Premises
     to the original Attachmate Tenant Improvements at the end of the Term,
     reasonable wear and tear, casualty or condemnation accepted. Mercata shall
     bear the full cost and expense of modifying or renovating the Subleased
     Premises for its use. All wiring and cabling of the Subleased Premises for
     Mercata's purposes shall be at its own expense. Mercata and Attachmate
     shall meet prior to such date to work out a reasonable and mutually
     acceptable schedule for such installation, including, but not limited to
     the use of the freight elevator.

                                       4

     Mercata shall, at the end of the Term, or upon sooner termination of this
     Sublease pursuant to the terms hereof, promptly surrender the Subleased
     Premises in good order and condition and in conformity with the applicable
     provisions of this Sublease, and the Master Lease, excepting only
     reasonable wear and tear, fire or other casualties or condemnation. Mercata
     shall at the request of Attachmate remove any improvements made to the
     Subleased Premises in accordance with this Section, so that only the
     Attachmate Tenant Improvements are surrendered with the Subleased Premises.

10.  ALTERATIONS AND MODIFICATIONS: Mercata agrees to obtain Attachmate's and
     -----------------------------
     Bentall's prior written approval of alterations, modifications, repairs or
     renovations made to the Subleased Premises and such request shall be
     submitted to Bentall and Attachmate in the manner required under Section
     25A of the Master Lease, except that Mercata shall not be excluded from
     seeking approval from Attachmate (but shall be excluded from seeking
     approval from Bentall) for improvements which cost less than Ten Thousand
     and No/100 Dollars ($10,000.00). Mercata acknowledges that Attachmate and
     Bentall's approval of alterations, modifications, repairs or renovations
     may be conditioned as set forth in the Master Lease.

     Any alterations, modifications or renovations of or to the Subleased
     Premises shall be limited to partition changes (non-bearing walls),
     electrical and mechanical alterations, telephone relocations, and
     decorating. The structural integrity of the Building will not be disturbed
     in any way. Mercata shall provide Attachmate and Bentall with a release of
     liens at the completion of any alterations or modifications to the
     Subleased Premises executed by all contractors who performed such
     alterations or modifications. In addition, Mercata agrees that all work
     performed upon the Subleased Premises shall be done in a good and
     workmanlike manner and shall be in accordance with all applicable law. All
     permanent alterations, modifications and renovations, upon completion of
     construction thereof, at the option of Attachmate, shall become part of the
     Subleased Premises and the property of Attachmate without payment therefor
     by Attachmate and shall, at the option of Attachmate, be surrendered to
     Attachmate at the end of the Term, any extended term or upon sooner
     termination of this Sublease pursuant to the terms of the Sublease or
     Master Lease.

11.  OBLIGATIONS UNDER MASTER LEASE CONTROLLING: Except as herein provided, and
     ------------------------------------------
     except for Attachmate's obligation to pay the Basic Rent and Additional
     Rent pursuant to Sections 3 and 4 of the Master Lease, Mercata agrees to
     comply with all of the terms and conditions set forth in the Master Lease
     applicable to Attachmate and related to the Subleased Premises and that are
     to be performed by Mercata as subtenant under this Sublease; provided that
     Mercata shall not have any liability for any default arising due to the
     action or inaction of Attachmate, whether monetary or otherwise, under the
     Master Lease. All of the terms and conditions of the Master Lease related
     to the Subleased Premises shall apply in the same manner to Mercata as they
     are expressed therein to apply to Attachmate under the Master Lease except
     as modified or deleted pursuant to the terms of this Sublease. Attachmate
     covenants and agrees to perform all of its obligations under the Master
     Lease and will assist Mercata in coordinating Bentall's services and
     obligations required to be provided and fulfilled by Bentall under the
     Master Lease. Notwithstanding the foregoing, Attachmate shall have no
     obligation to pursue available remedies provided for in the Master Lease in
     the event Bentall defaults under the Master Lease or Bentall fails to
     comply with or perform any of its services, duties, obligations or
     covenants under the Master Lease. Mercata shall have all self-help rights
     and other rights and remedies that Attachmate has under the Master Lease,
     including rights and remedies in the event Bentall defaults under the
     Master Lease or Bentall fails to comply with or perform any of its
     services, duties, obligation or covenants under the Master Lease. Mercata's
     obligations under this Sublease, including without limitation Mercata's
     obligations to pay Rent, shall abate to the same extent that Attachmate's
     obligations under the Master Lease would abate with respect to the
     Subleased Premises.

12.  MASTER LEASE IN EFFECT: Attachmate represents and warrants, to the best of
     ----------------------
     its knowledge, that the Master Lease is in full force and effect, and that
     neither Attachmate nor Bentall are in default thereunder. Attachmate shall
     not do or permit anything to be done which would be a default under the
     Master Lease after the expiration of any applicable cure periods or which
     would cause the Master Lease to be terminated or forfeited, and Attachmate
     shall indemnify, defend and hold Mercata harmless from and against any and

                                       5
<PAGE>

     all claims, demands, losses, damages, and costs and expenses arising out of
     or relating to Attachmate's default under the Master Lease.

13.  SUBLEASING OR ASSIGNMENT: In the event Mercata desires to sublease or
     ------------------------
     assign all or any portion of the Subleased Premises or this Sublease, it
     shall be bound to the terms and conditions of Section 8 of the Master
     Lease, except all notices shall be delivered and all approvals obtained
     from both Bentall and Attachmate. The obligation of Bentall and Attachmate
     to consent to such subletting or assignment shall be as outlined in the
     Master Lease; provided that in no event shall Attachmate's consent be
     unreasonably withheld, conditioned or delayed. Any sublease or assignment
     by Mercata shall be subject to the terms and conditions of the Master
     Lease, including, without limitation Section 8.4 and 8.5 of the Master
     Lease. Attachmate and Mercata acknowledge that the terms and conditions of
     Section 8.8 of the Master Lease shall not apply, as the Sublease Limit will
     not be reached due to this Sublease. The consent to a sublease or
     assignment from Attachmate shall not be construed as relieving Mercata or
     any assignee of the Sublease or sublessee of the Subleased Premises from
     obtaining the express written consent of Bentall and Attachmate to any
     further assignment or subletting or obligation hereunder whether or not
     then accrued.

     Any modifications or improvements necessary as a result of such sublease or
     assignment must be approved as required in Section 10 above and Mercata
     agrees to restore the Subleased Premises to the condition required in
     Section 9 at the end of the term of such sub-sublease or assignment.

14.  INSURANCE AND INDEMNITY; WAIVER:
     -------------------------------

14.1  Mercata shall obtain and keep in full force and effect the insurance
      required by Attachmate under Section 13 of the Master Lease and shall name
      Bentall and Attachmate as additional insureds. Within fifteen (15)
      business days of execution of this Sublease, Mercata shall furnish to
      Bentall and Attachmate a certificate or certificates of insurance
      confirming that the required insurance is in full force and effect with
      all premiums paid current. Mercata further agrees to indemnify and hold
      harmless Attachmate and Bentall from all liability arising out of the
      filing of any mechanic's or materialman's lien against the Subleased
      Premises by reason of any act or omission of Mercata.

14.2  Attachmate and Mercata each waive their right to sue and recover damages
      against each other with respect to any liability arising under the Master
      Lease or this Sublease and which is or is required to be covered by any
      insurance policy maintained by any party, regardless of the cause of such
      damage.

15.  PERSONAL PROPERTY: Mercata agrees to assume full responsibility for its
     -----------------
     personal property located at the Subleased Premises, and to indemnify and
     hold harmless Attachmate and Bentall against damage to Mercata's personal
     property sustained by fire, theft or other casualty loss.

17.  HOLD OVER: Notwithstanding any provision of law or any judicial decision to
     ---------
     the contrary, and unless Mercata has exercised its option to extend the
     Term, no notice shall be required to terminate the Term on the date herein
     specified as the end of the Term, and the Term shall expire on the date
     herein mentioned without notice being required from either party. In the
     event that Mercata remains beyond the expiration date of the Term or as
     extended, without the prior written consent of Attachmate, it is the
     intention of the parties and it is hereby agreed that a tenancy at
     sufferance shall arise at a monthly rent equal to One Hundred Fifty Percent
     (150%) of the Rent due under this Sublease.

18.  MERCATA'S DEFAULT: The occurrence of any one or more of the following
     -----------------
     events shall constitute an event of default under this Sublease by Mercata:

     a. The failure by Mercata to make any payment of Rent or any other payment
     required to be made by it hereunder on the date due where such failure
     shall continue for a period of five (5) days after receipt of written
     notice of such failure from Attachmate.

                                       7
<PAGE>

     b. The failure by Mercata to observe or perform any of the covenants,
     conditions or provisions of this Sublease other than as described in the
     immediately preceding paragraph and/or the failure by Mercata to observe or
     perform any of the covenants, conditions or provisions of the Master Lease
     to which Mercata has agreed to be bound pursuant to the terms of this
     Sublease, where such failure shall continue for a period of fifteen (15)
     days after written notice thereof from Attachmate to Mercata and such
     additional time, if any, as is reasonably necessary to cure such default if
     such default is of such a nature that it cannot reasonably be cured within
     fifteen days, provided that Mercata diligently prosecutes such cure in good
     faith and with due diligence and provided that such cure is completed
     within sixty (60) days from the date of such notice from Attachmate.

     c. The making by Mercata of any general arrangement or assignment for the
     benefit of creditors; Mercata becomes a "debtor" as defined in 11 U.S.C.
     101 or any successor statute thereto (unless, in the case of a petition
     filed against Mercata, the same be dismissed within sixty (60) days); the
     appointment of a trustee or receiver to take possession of all or
     substantially all of Mercata's assets or of Mercata's interest in this
     Sublease, where possession is not restored to Mercata within thirty (30)
     days; or the attachment, execution or other judicial seizure of all or
     substantially all of Mercata's assets or of Mercata's interest in this
     Sublease, where such seizure is not discharged within thirty (30) days.

19.  REMEDIES: In the event of any such default by Mercata, Attachmate may at
     --------
     any time thereafter, without limiting Attachmate in the exercise of any
     right or remedy which Attachmate may have by reason of such default or
     breach:

     a. Upon the occurrence of an event of default, Attachmate at any time
     thereafter may give written notice to Mercata specifying such event of
     default and stating that either this Sublease shall expire or Mercata's
     right to possession shall expire on the date specified in such notice but
     not less than thirty (30) days after the date that Mercata receives said
     notice and upon the date specified in such notice.

     b. Upon the termination of this Sublease or Mercata's possession of the
     Subleased Premises pursuant to paragraph a. of this Section, Mercata shall
     peacefully surrender the Subleased Premises to Attachmate, and Attachmate,
     upon or at any time after any such expiration, may without further notice
     reenter the Subleased Premises and repossess it by summary proceedings,
     ejectment, or otherwise, and may dispossess Mercata and remove Mercata and
     all other persons and Mercata's property from the Subleased Premises and
     may have, hold, and enjoy the Subleased Premises including the right to
     receive all rental income therefrom.

     c. At any time after any such termination, Attachmate may relet the
     Subleased Premises or any part thereof, in the name of Attachmate or on
     behalf of Mercata, for such term (which may be greater or less than the
     period which would otherwise have constituted the balance of the term of
     this Sublease) and on such conditions (which may include concessions or
     free rent) as Attachmate, in its reasonable discretion, may determine, and
     may collect and receive the rent therefore. Attachmate shall mitigate its
     damage by making reasonable efforts to relet the Premises on reasonable
     terms. Attachmate shall be entitled to all reasonable expenses incurred in
     connection with such mitigation, including without limitation, all
     repossession costs, brokerage commissions, legal expenses, reasonable
     attorneys fees, and expenses of preparation for such reletting (but
     excluding any tenant allowances or tenant improvement costs).

     d. No such termination of this Sublease or Mercata's possession of the
     Subleased Premises shall relieve Mercata of its liability and obligations
     under this Sublease, and such liability and obligations shall survive any
     such termination. In the event of any termination of this Sublease, if the
     Subleased Premises has not been relet, Mercata shall pay to Attachmate the
     present value of the Rent and any other amounts required to be paid by
     Mercata until the end of what would have been the Term of this Sublease,
     less the present value of the anticipated fair and reasonable rental value
     of the Subleased Premises over the same period.

                                       8
<PAGE>

     e. In the event of a termination of this Sublease after the Subleased
     Premises has been relet or the termination of Mercata's possession of the
     Subleased Premises, Mercata shall pay to Attachmate as damages for
     Mercata's default:

     (1)  The amount of the Rent and any other amounts which would be payable
          under this Sublease by Mercata if this Sublease were still in effect,
          less

     (2)  The net proceeds of any reletting affected pursuant to paragraph c. of
          this Section.

     Mercata shall pay such current damages, herein called deficiency, to
     Attachmate monthly on the days on which the Rent would have been payable
     under this Sublease if this Sublease were still in effect, and Attachmate
     shall be entitled to recover from Mercata each monthly deficient, as or at
     any time after such deficiency shall arise. If the Subleased Premises or
     any part thereof is relet by Attachmate for the unexpired Term, including
     any extension thereof, or any part thereof, before presentation of proof of
     such damages to any court, commission, or tribunal, the amount of rent
     reserved upon such reletting shall be deemed prima facie to be the fair and
     reasonable rental value for the part or the whole of the Subleased Premises
     so relet during the term of the reletting. Nothing herein contained shall
     limit or prejudice the right of Attachmate to prove for and obtain as
     damages by reason of such termination an amount equal to the maximum
     allowed by any statute or rule of law in effect at the time when, and
     governing the proceedings in which, such damages are to be proved, whether
     or not such amount be greater, equal to, or less than the amount of the
     difference referred to above.

     f.  Pursue any other remedy now or hereafter available to Attachmate under
     the laws of the State of Washington or in equity. All remedies available to
     Attachmate hereunder shall be cumulative and concurrent. No waiver or delay
     in enforcement by Attachmate of any breach of Mercata's obligations
     hereunder shall constitute a waiver of any such breach or any subsequent
     breach.

20.  INTEREST: In the event that any sums due and payable to Attachmate pursuant
     --------
     to the terms of this Sublease are not paid when due, such sums shall bear
     interest at the rate specified in Section 3.3 of the Master Lease, but in
     no event less than the prime rate as published by Bank of America, N.A.
     plus two percent (2%), as published from time to time, from the due date
     until actually paid, unless that rate is usurious as applied to Mercata in
     which event the rate shall be reduced to the highest non-usurious rate.
     Neither the accrual nor the payment of interest shall cure any default by
     Mercata under this Sublease.

21.  BROKERS: Mercata is represented by The Broderick Group, Inc. and Attachmate
     -------
     is represented by Colliers International in connection with the negotiation
     of this Sublease. Attachmate is responsible for a commission to Colliers
     International with whom it has a separate agreement.

22.  COMPLIANCE WITH LAWS: This Sublease will be construed and enforced in
     --------------------
     accordance with the laws of the State of Washington.

23.  AUTHORITY: If Mercata executes this Sublease as a corporation, then Mercata

     and the person executing this Sublease on behalf of Mercata represents and
     warrants that the individuals executing this Sublease on Mercata's behalf
     are duly authorized to execute and deliver this Sublease on its behalf in
     accordance with a duly adopted resolution of the Board of Directors of
     Mercata, a copy of which is to be delivered to Attachmate on execution
     hereof, and in accordance with the Bylaws of Mercata and that this Sublease
     is binding upon Mercata in accordance with its terms. If Attachmate
     executes this Sublease as a corporation, then Attachmate and the person
     executing this Sublease on behalf of Mercata represents and warrants that
     the individuals executing this Sublease on Attachmate's behalf are duly
     authorized to execute and deliver this Sublease on its behalf in accordance
     with a duly adopted resolution of the Board of Directors of Attachmate.

<PAGE>

24.  FURTHER DOCUMENTS: Each party agrees to execute and deliver to the other
     -----------------
     all instruments which may reasonably be required to carry out all terms and
     provisions of this Sublease.

25.  RECOVERY OF COSTS AND FEES: If either party shall bring any civil action to
     --------------------------
     enforce any of its rights under this Sublease or for any relief against the
     other party with regard to the matters contained in this Sublease or if
     either party incurs any legal or professional fees whatsoever (including
     but not limited to those of appraiser's accountant's or any payments to
     collection agents) to enforce this Sublease whether or not such enforcement
     efforts proceed to the filing of a lawsuit, then all reasonable costs and
     expenses, including without limitation reasonable attorney's and
     professional fees of the prevailing party shall be paid by the losing
     party.

26.  BINDING EFFECT: This Sublease shall be binding upon the successors and
     --------------
     permitted assigns of Mercata and Attachmate.

27.  LEGAL RELATIONSHIP OF THE PARTIES: This Sublease shall not be interpreted
     ---------------------------------
     or construed as establishing a partnership or joint venture between
     Attachmate and Mercata, and neither party shall be liable for the debts or
     obligations of the other, except as expressly agreed to herein.

28.  INTEGRATED DOCUMENT: This instrument embodies all of the agreements between
     -------------------
     the parties with respect to the Subleased Premises, and no oral agreements,
     prior correspondence or other prior writings shall be held to vary the
     provisions hereof. Any subsequent changes or modifications shall become
     effective only by a written instrument duly executed by Mercata and
     Attachmate.

29.  CONSENT REQUIRED: This Sublease is contingent upon, and shall have no force
     ----------------
     or effect until receipt of consent by Bentall.

30.  RIGHT OF FIRST OFFER: Mercata shall have an exclusive, ongoing Right of
     --------------------
     First Offer on all additional space Attachmate wishes to sublease on floor
     five of the Building. In the event any such space becomes available,
     Attachmate shall so notify Mercata in writing. Mercata shall notify
     Attachmate in writing within thirty (30) days thereafter regarding whether
     Mercata desires to sublease such space. If Mercata notifies Attachmate of
     its desire to sublease such space, then such space shall be added to the
     Subleased Premises as of the date that is thirty (30) days after
     Attachmate's receipt of Mercata's notice that it is willing to sublease
     such space. Any sublease of such space shall be on the same terms and
     conditions contained in this Sublease, except that Base Rent for such space
     shall be at the then prevailing market rent for comparable Bellevue area
     office space but in no instance less than the rate Mercata is paying to
     lease the Subleased Premises per this Sublease. The term for the additional
     subleased space shall be coterminous with the Sublease Term. In the event
     Mercata fails to respond to Attachmate's notice within the thirty (30) day
     period, Mercata's right to exercise the Right of First Offer shall lapse
     and be of no further force or effect.

31.  PARKING: Mercata shall have the right to use four (4) parking stalls per
     -------
     thousand rentable square feet of the Subleased Premises (as the same may be
     expanded as provided in Section 30 or otherwise) during the sublease Term
     or any extensions free of charge in the Four Newport garage.

32.  ROOF ACCESS: Mercata shall have access to roof rights for communications
     -----------
     equipment at no additional charge throughout the Term or any extensions

33.  MERCATA SIGNAGE: Subject to Attachmate's approval, Mercata shall be
     ---------------
     permitted to display a sign or plaque on the reception desk at the entry to
     the Building. Interior signage installed by Mercata in the Subleased
     Premises shall be at its own expense and such signage will be removed at
     the end of the Term and any extension thereof at Mercata's expense and
     subject to repair of damage caused by such removal.

34.  QUIET ENJOYMENT: Attachmate covenants and agrees that so long as Mercata
     ---------------
     performs all of the covenants on Mercata's part to be observed and

     Mercata shall and peaceably quietly have, hold and enjoy the Subleased

                                  FOUR NEWPORT
                             OFFICE BUILDING LEASE

  THIS LEASE, dated as of April 29, 1998, is made and entered into by and
between Bentall Newport Centre L.L.C., a Washington limited liability company
("Landlord"), and Attachmate Corporation, a Washington corporation ("Tenant").

  WITNESSETH, THAT:

1.  PREMISES

  1.1  Land, Building & Link.  Landlord shall erect, pursuant to the Building
       ---------------------
Shell Construction Documents and Description of Building and Parking Garage
Shell attached as Exhibit "C-2" and "C-3" hereto, on the real property described
in Exhibit "A" located in King County, Washington (the "Real Property"), a six
(6) story office building as further specified in this Lease and Exhibits
attached hereto, collectively known as the Four Newport Building (the
"Building"), together with an enclosed walkway between the Building and the
adjoining Newport Terrace Building (the "Link") as further specified in this
Lease and Exhibits attached hereto.  Landlord's obligation to construct the
Building, Tenant Improvements (as defined in Exhibit "C"), and Link is set forth
in Section 25 herein.  Landlord shall obtain all permits required by local,
state or federal law relating to the construction of the Building Shell (as
defined in Exhibit "C") and will otherwise comply with any and all laws related
to the construction thereof.  Tenant's sole and exclusive remedy for Landlord's
failure to obtain all permits relating to the construction of the Building shell
and core in accordance with the preceding sentence shall be to terminate this
Lease in accordance with the provisions of Section 2.1(d)(iii) below. Landlord
shall also use its good faith reasonable best efforts to obtain all permits
required by local, state or federal law relating to the construction of the Link
and will otherwise comply with any and all laws related to the construction
thereof, provided, however, Landlord shall have no liability to Tenant for a
delay in the completion of the Link if Landlord is unable, despite Landlord's
good faith efforts, to obtain all permits and governmental approvals necessary
for the construction of the Link.

  1.2  Premises.  Landlord, subject to the terms and conditions hereof, hereby
       --------
leases to Tenant and Tenant hereby leases from Landlord the entire first (1st),
second (2nd), third (3rd) and fourth (4th) floors of the Building, which
includes approximately 100,328 square feet of Rentable Area, and 87,682 square
feet of Useable Area, together with access thereto (including without limitation
the Link) and parking as provided in Section 34.6 of this Lease (collectively
the "Premises"). The floor plates for the first (1st), second (2nd), third (3rd)
and fourth (4th) floors of the Building are shown on Exhibits "A-2" through
"A-5." Tenant may use the Premises for general office purposes, computer
operations, research and development laboratories, athletic facilities for
Tenant's employees, food services for Tenant's employees, warehouse, product
assembly, distribution center, storage, shipping and receiving and for no other
use without Landlord's prior written consent, which consent shall not be
unreasonably withheld, conditioned or delayed.

                                       1
<PAGE>

  1.3  Agreed Floor Areas. The agreed Building Rentable Area of the Building is
       ------------------
approximately 153,181 square feet.  The Premises contains approximately 100,328
square feet of Rentable Area and 87,682 square feet of Useable Area, subject to
final measurement and space planning in accordance with and based on the
definitions of those phrases in the Standard Method for Measuring Floor Area in
Office Buildings (An American National Standard ANSI/BOMA Z65.1-1996 (Revised
and readopted June 7, 1996) published by Building Owners and Managers
Association International ("BOMA Standard"), as set forth on Exhibit "B" (which
may be amended based on final measurements).  All final square footages shall be
determined by Landlord's architect (the "Architect") and verified by Tenant's
architect.  Verification shall be  per  BOMA Standard for a multi-tenant
building unless Tenant leases the entire Building, in which case verification
shall be based on a single-tenant building. Any dispute regarding the
determination of the final square footages shall be resolved in accordance with
Section 17.7 below.  Initial square footage calculations have been completed
prior to Lease execution, and shall be redone prior to the Commencement Date (as
defined in Section 2.1 below).  Notwithstanding the foregoing or the BOMA
Standard, the parties agree that the square footage of the Link shall not be
used in calculations to determine the Useable Area or Rentable Area of the
Premises, and no Rent (as defined in Section 3.2 below) shall be payable during
the Term (as defined in Section 2 below) for the Link except as expressly set
forth in subsection 3.1A below.

  1.4  Acceptance of Property and Premises.  Neither Landlord nor its agents
       -----------------------------------
have made any representations with respect to the Building, the Real Property,
or the Premises, except as expressly set forth herein and no rights, easements,
or licenses are acquired by the Tenant by implication or otherwise except as
expressly set forth in this Lease, together with its Exhibits.  Landlord shall
deliver the Premises on the date of Substantial Completion of the Building and
Tenant Improvements, as defined more fully below.

       (a)  "Substantial Completion" or "Substantially Complete" means that the
Building Shell, parking, common areas, and Tenant Improvements (as defined in
Exhibit "C") in the Premises shall have been completed in accordance with the
Building Shell Construction Documents and the Tenant Improvement Construction
Documents (as those terms are defined in Exhibit "C"), but specifically
excluding the Link (which shall be completed in accordance with Section 25.6
below), which Substantial Completion shall be conclusively deemed to have
occurred upon issuance by the City of Bellevue of a temporary certificate of
occupancy for the Building and Premises (such temporary certificate of occupancy
to be obtained by Landlord) and issuance by the Architect of a Certificate of
Substantial Completion for the Tenant Improvements, which Certificate of
Substantial Completion shall be in the form of AIA Document G704. The existence
of punchlist items or additional work required for issuance of a final
certificate of occupancy by the City of Bellevue shall not be matters which will
delay Substantial Completion from having occurred; provided that Landlord shall
use diligent efforts to obtain Final Completion (as defined below) within sixty
(60) days thereafter or as soon as reasonably practical if any such punchlist
item or work required for issuance of a final certificate of occupancy cannot be
completed within such sixty (60) day period. If Landlord fails to obtain Final
Completion within sixty (60) days after Substantial Completion or as soon as
reasonably practical if any punchlist item or work required for issuance of a
final certificate of occupancy cannot be completed within sixty (60) days,
Tenant shall have the right, after five (5) days written notice to Landlord, to
complete the work necessary for Final Completion and Landlord shall reimburse
Tenant for the reasonable cost of completing such work within ten (10) days of

                                       2
<PAGE>

Landlord's receipt of invoices for such work. Notwithstanding the above to the
contrary, if, after the execution of this Lease, Tenant's design decisions,
revisions, or additional work of Tenant or its agents or architect delays
Substantial Completion, then to the extent such delay is determined to be caused
by or attributable to Tenant or its agents or architect, the date of Substantial
Completion shall be deemed to have occurred on the date Substantial Completion
would otherwise be established absent such delay.

     (b)  "Final Completion" with reference to the Building Shell, parking and
common areas, and Tenant Improvements in the Premises means such items are
Substantially Complete, all punchlist items have been complete, and a final
certificate of occupancy for the Building Shell, parking, common areas and
Tenant Improvements in the Premises has been issued.

     (c)  Landlord warrants to Tenant that the materials and equipment used and
installed in the Building Shell, Tenant Improvements and the Link, are new, of a
first class quality, are in conformance with the documents attached hereto as
Exhibit "C" and that all work shall be in compliance with all applicable codes.
Landlord shall proceed diligently with all aspects of the construction and any
repairs due to initial construction defects and latent defects, upon Landlord's
knowledge thereof. Landlord agrees it will enforce its contractual agreements
with Landlord's architect and general contractor. For a period of one (1) year
from the date of Substantial Completion of each of the Building Shell, Tenant
Improvements, and Link (if constructed), Landlord shall remedy, repair or
replace, in the manner specified by Tenant all defects, deficiencies in
workmanship and materials in the Building Shell, Tenant Improvements, and Link.

  1.5  Common Areas.
       ------------

     (a)  Building Common Areas.  Tenant shall have the nonexclusive right to
          ---------------------
use in common with other tenants in the Building the following areas ("Building
Common Areas") appurtenant to the Premises: The Building's common entrances,
lobbies, trash areas, restrooms, elevators, stairways and access ways, loading
docks, shipping and receiving areas, ramps, drives and platforms and any
passageways and service ways thereto, and the common pipes, conduits, wires and
appurtenant equipment serving the Premises (provided however, that
notwithstanding the foregoing, the Link is not a common area and is reserved for
the exclusive use of the Tenant). Landlord agrees to install at no cost to
Tenant two conduits (with pull-strings) leading from the Newport Terrace
Building to the Building and agrees to use its reasonable best efforts to
dedicate one conduit within the Newport Corporate Center (as hereafter defined)
for Tenant's exclusive use provided that such dedication can be accomplished at
no additional cost and provided that Tenant shall remove all cabling within such
conduits at the expiration or termination of this Lease if requested by Landlord
by cutting and pulling the cabling out of the conduit(s). If Landlord is unable
to dedicate a conduit for Tenant's exclusive use, Landlord shall use its
reasonable best efforts to minimize any interruptions within the conduits from
use by other tenants.

     (b)  Newport Corporate Center Common Areas.  Tenant shall also have the
          -------------------------------------
nonexclusive right to use in common with other tenants of the Newport Corporate
Center (as defined below) the following areas ("Newport Corporate Center Common
Areas"): Common facilities made available for or for the benefit of all tenants
within the Newport Corporate Center

                                       3
<PAGE>

including, without limitation, landscaping, roadways, pedestrian walkways, and
parking areas, but specifically excluding the use of any future fitness center.
The term "Newport Corporate Center" shall mean the properties and buildings
located thereon commonly known as One Newport, Two Newport, Newport Tower,
Newport Heights, Newport Terrace and Four Newport (the names of which Landlord
may change from time to time subject to Section 34.14), together with such other
additional properties and/or buildings which Landlord may add in the future.

     (c)  Definition of Common Areas.  The term "Common Areas" as used in this
          --------------------------
Lease shall include the Building Common Areas and the Newport Corporate Center
Common Areas.

     (d)  Landlord reserves the right from time to time, upon reasonable prior
notice to Tenant and without either expense to Tenant or unreasonable or
prolonged interference with Tenant's use:

         (i)  To install, use, maintain, repair and replace pipes, ducts,
conduits, wires and appurtenant meters and equipment for service to other parts
of the Building above the ceiling surfaces, below the floor surfaces, within the
walls and in the central core areas of the Premises, and to relocate any pipes,
ducts, conduits, wires and appurtenant meters and equipment included in the
Premises for the benefit of the Premises or other parts of the Building;

       (ii) To make changes to the Common Areas, including, without limitation,
changes in the location, size, shape and number of driveways, entrances, parking
spaces, (as long as the parking ratio of four (4) parking spaces per 1000 square
feet of Useable Area, as stated in Section 34.6 is maintained) parking areas (as
long as not substantially different from the plans approved by Tenant for such
parking areas), loading and unloading areas, ingress, egress, direction of
traffic, landscaped areas and walkways;

      (iii)  To close temporarily any of the Common Areas for maintenance
purposes so long as reasonable access to the Premises remains available and the
maintenance promptly started and diligently pursued to completion;

       (iv) To use the Common Areas while engaged in making additional
improvements, repairs or alterations to the Building, or any portion thereof;

        (v)  To establish, reasonably modify or change rules governing the move-
in and move-out procedures of Tenant's furniture, equipment, and fixtures, so
long as not adversely discriminatory against Tenant compared to other tenants of
the Building and effective only after Tenant has received a copy of such rules;

       (vi) To designate other land located within Newport Corporate Center to
be part of the Newport Corporate Center Common Areas for the use of all tenants
of Newport Corporate Center associated with a building yet to be built now known
as Five Newport;

      (vii)  To add additional improvements to the Common Areas which, with
respect to the Building Common Areas shall be for the general benefit of all
tenants of the

                                       4
<PAGE>

Building and, with respect to the Newport Corporate Center Common Areas shall be
for the general benefit of the Newport Corporate Center.

      Nothing contained in this Section 1.5(d) shall (1) limit Landlord's right
to charge or Tenant's obligation to pay "Operating Costs" as that term is
defined in Section 4.3 below, or (2) expand on Landlord's right to charge or
Tenant's obligation to pay capital costs as set forth in Section 4.3 below. In
addition, notwithstanding the provisions of this Section to the contrary, Tenant
shall have the right to approve alterations to the Common Areas which materially
affect the Building (other than alterations required by governmental
authorities) during such time(s) as Tenant occupies the entire Building.

     (e)  If Landlord makes any changes, alterations or additions to the
Premises, the Common Areas, or to the Newport Corporate Center common areas
(including, without limitation, the construction of new buildings), such
changes, alterations or additions shall not interfere with the public
accessibility to the Premises, including without limitation Tenant's parking,
and shall not interfere with Tenant's utility services, including without
limitation all electricity, gas, water, sewer, and telecommunications services
to the Premises. If such interference should occur for any reason, Landlord
shall make immediate efforts to restore such accessibility or services in
coordination and cooperation with Tenant. Further, if such interference should
occur due to the acts or omissions of Landlord or its agents, then following
notice to Landlord and two (2) business days' opportunity to cure the
interference, Rent due under this Lease shall abate to the extent of the
interference from the date of the interference until such interference is cured
and Tenant shall be entitled to recover its damages arising from such
interference (excluding consequential damages such as lost profits).

     (f)  Since Tenant is also an existing tenant of the existing building
("Newport Terrace") to the north of the Building as well as other buildings in
the Newport Corporate Center, the parties anticipate the need for Landlord to
take reasonable steps to minimize any interference with the operation of
Tenant's business at Newport Corporate Center and Tenant's quiet enjoyment
during the period in which the balance of Newport Corporate Center is
constructed (including the construction of the Building as well as any future
buildings). Therefore, Landlord shall give Tenant advance notice on a regular
basis of construction activities at Newport Corporate Center, and particularly
of any activity at Newport Corporate Center that may result in interference with
Tenant's operations at the buildings occupied by Tenant. Examples of these
activities might include excavation around existing utilities, grading and
construction of roads, and access ways, and work on drainage systems. To the
extent reasonably possible, Landlord shall accommodate Tenant's wishes
concerning any planned interruptions of access or utilities at the buildings
occupied by Tenant. Any such planned interruptions shall be done in consultation
and coordination with Tenant. Any accidental interference by Landlord with
Tenant's use of space at Newport Corporate Center, whether interference with
access, utilities or otherwise, shall be promptly remedied by Landlord. If
interference with Tenant's use of the Premises should occur due to the acts or
omissions of Landlord or its agents, then following notice to Landlord and two
(2) business days' opportunity to cure the interference, Rent due under this
Lease shall abate to the extent of the interference from the date of the
interference until such interference is cured and Tenant shall be entitled to
recover its damages arising from such interference (excluding consequential
damages such as lost profits). The same provision as is set forth in the

                                       5
<PAGE>

preceding sentence shall be included in each of the Amendments (as defined in
Section 36 below) to cover the space leased by Tenant in the other buildings in
Newport Corporate Center.

     (g)  In the event of any interference with Tenant's use of the Premises
which is not due to the acts or omissions of Landlord or its agents nor due to
the acts or omissions of Tenant or its agents and such interference is not
remedied within one hundred twenty (120) days from the date of interruption,
Rent due under this Lease shall abate to the extent of the interference from the

  1.6    Exclusive Expansion Right.  Landlord hereby grants Tenant an exclusive
         -------------------------
expansion right to lease the entire fifth (5th) floor, or the entire sixth (6th)
floor, or the entirety of both the fifth (5th) and sixth (6th) floors of the
Building (the "Four Newport Expansion Space") on the terms set forth in this
Section 1.6. The Four Newport Expansion Space encompasses approximately 52,853
square feet of rentable area and 46,056 square feet of useable area, as
delineated on Exhibits "A-6" -"A-7", subject to final measurement and space
planning according to the BOMA Standard. This exclusive expansion right is
subject to the following terms and conditions:

     (a)  Exercise.  Tenant exercises this exclusive expansion right by giving
          --------
Landlord written notice of exercise (the "Exercise Notice") on or before 6:00
p.m. Seattle, Washington time on the date which is the later to occur of
November 12, 1998, or twelve (12) months prior to the date of Substantial
Completion (based on the estimated date of Substantial Completion as set forth
in the Construction Agreement (as defined below in Section 2.1(b)) and as such
estimated date may change from time to time based on the most recent schedule
prepared by the General Contractor). The Exercise Notice shall state the amount
of the Four Newport Expansion Space it wishes to add to the Premises under this
Lease, which must be the entire fifth (5th) floor, or the entire sixth (6th)
floor, or the entirety of both floors. Notice is not effective if Tenant is in
default under this Lease at the time of the exercise. If, within ninety (90)
days following Tenant's delivery of the Exercise Notice, the Scheduled
Substantial Completion Date (as defined in the Construction Agreement) in effect
on the date of the delivery of Tenant's Exercise Notice is changed to a date
more than ninety (90) days later than such Scheduled Substantial Completion
Date, then Tenant shall have three (3) business days from Tenant's receipt of
notice of such change to rescind the Exercise Notice by giving written notice of
rescission to Landlord. Landlord agrees to notify Tenant of any changes in the
Scheduled Substantial Completion Date when Landlord becomes aware of such
changes.

     (b)  Addition to Premises.  If Tenant exercises this exclusive expansion
          --------------------
right in accordance with Subsection 1.6(a) above, then the portion of the Four
Newport Expansion Space described in the Exercise Notice shall be added to the
definition of Premises so that it is constructed in accordance with this Lease
and leased to and rent is payable by Tenant beginning on Substantial Completion
of the Tenant Improvements for the applicable portion of the Four Newport
Expansion Space, including Rent (defined in Section 3 below) and otherwise
leased on the same terms and conditions as contained in this Lease. An amendment
to this Lease shall be prepared by Landlord and signed by the parties adding
that portion of the Four Newport Expansion Space stated in the Exercise Notice
to the Premises under this Lease, including Exhibits similar to those attached
as Exhibit "A-6" and "A-7" describing such space.

                                       6
<PAGE>

     (c)  Termination.  This exclusive expansion right automatically terminates
          -----------
at 6:01 p.m. on the date which is the later to occur of November 12, 1998, or
twelve (12) months prior to the date of Substantial Completion (based on the
estimated date of Substantial Completion as set forth in the Construction
Agreement and as such estimated date may change from time to time based on the
most recent schedule prepared by the General Contractor), and Landlord shall
thereafter be free to lease the Four Newport Expansion Space to any third party
that is not a Direct Competitor (as defined in Section 1.8 below).

     (d)  Limitation.  This exclusive expansion right is not assignable
          ----------
separate and apart from this Lease, and may only be exercised by Tenant or its
assignee as permitted under Section 8 of this Lease.

  1.7  Right of First Opportunity. Landlord hereby grants Tenant a "Right of
       --------------------------
First Opportunity" to lease any space which becomes available in the One Newport
Building (the "Opportunity Space"), which space is legally described in Exhibit
"A-8" attached hereto, and delineated on Exhibits "A-9" through "A-12" attached
hereto.  This Right of First Opportunity is subject to the following terms and
conditions:

     (a)  Availability of Opportunity Space.  Opportunity Space shall be deemed
          ---------------------------------
available for purposes of triggering Landlord's Notice (as defined below) when
one hundred fifty (150) or fewer days remain in the term of any lease of any
such Opportunity Space (subject, however, to any existing leases, rights of
extension or other option rights of leases existing on the date hereof). If,
however, the tenant who has possession of and/or rights to the affected
Opportunity Space does not vacate the Opportunity Space at the end of the lease
term and if Tenant elects to lease that Opportunity Space, then Landlord shall
promptly undertake eviction proceedings to make the space available and pursue
them to completion at its cost, but shall have no liability to Tenant for delay
in delivering possession of such space. Within three (3) days of Tenant's
request, Landlord shall provide Tenant with a list of all anticipated dates and
square footages of Opportunity Space which may become available.

     (b)  Landlord's Notice.  Landlord shall give Tenant written notice
          -----------------
("Landlord's Notice") at such time as any portion of the Opportunity Space
becomes available. Tenant shall have ten (10) working days from receipt of
Landlord's Notice to elect to take the Opportunity Space described in Landlord's
Notice. Tenant must make this election by written notice to Landlord within this
ten (10) working day period. Tenant's election to lease the Opportunity Space
offered is not effective if Tenant is in default under this Lease at the time of
Tenant's election or on the first day of the lease of such space. If Tenant
fails to exercise its Right of First Opportunity following receipt of a
Landlord's Notice within the ten (10) working day period, then Landlord is free
to lease that portion of the Opportunity Space described in Landlord's Notice to
any third party on any terms within six (6) months following the expiration of
such ten (10) working day period. If Landlord does not lease that portion of the
Opportunity Space described in Landlord's Notice within such six (6) month
period, Tenant's Right of First Opportunity with respect the space described in
Landlord's Notice shall continue with respect to that space. If Tenant exercises
its Right of First Opportunity with respect to any Opportunity Space, Tenant
shall not have any future right of first opportunity on that particular
Opportunity Space.

                                       7
<PAGE>

     (c)  Terms of Opportunity Space Lease.  If Tenant elects to lease
          --------------------------------
Opportunity Space described in any Landlord's Notice, Tenant's lease of the
applicable Opportunity Space shall commence on the date Tenant takes occupancy
of such space (so long as Tenant does not delay its occupancy for reasons within
its control for more than sixty (60) days following the date such space becomes
vacant, in which case the lease of such space shall commence on the sixtieth
(60th) day following such date). The lease of such Opportunity Space shall
be for a minimum lease term of three (3) years and shall otherwise be based on
fair market terms and conditions at the time the First Right of Opportunity is
exercised, including Basic Rent (described in Section 3 below), storage rent,
parking charges, and on such other terms and concessions as the parties may in
good faith negotiate, using this Lease as a starting point; provided, however,
if Landlord and Tenant are unable to agree on such fair market terms within
thirty (30) days following Landlord's receipt of Tenant's notice of Tenant's
election to lease the applicable Opportunity Space, then the "fair market terms"
shall be determined in accordance with the appraisal procedure described in
Section 2.2(a) below provided, however, the determination of "fair market terms"
shall not be limited to a determination of Basic Rent but shall include a
determination of all essential business terms including, without limitation,
Basic Rent, lease term, renewal options, allowances, storage space rent, parking
charges, and any other Landlord concessions. If the fair market terms are
determined through the procedure described in Section 2.2(a), Landlord and
Tenant agree that the provisions of this Lease other than the business terms
shall be used for the lease of the applicable Opportunity Space. Landlord shall
not be required to pay any brokerage commissions with respect to leases of the
Opportunity Space as provided in this Section.

    (d)  Termination. This Right of First Opportunity automatically terminates
         -----------
 on the date which is twelve (12) months prior to the expiration of the Term of
 this Lease (including any Extended Terms as described in Section 2.2 below).

    (e)  Limitation.  This exclusive expansion right is not assignable
         ----------
separate and apart from this Lease, and may only be exercised by Tenant or its
assignee as permitted under Section 8 of this Lease.

  1.8  Leases With Direct Competitors and Software Companies.  For the purposes
       -----------------------------------------------------
of this Lease, the term "Direct Competitor" shall mean Wall Data and Walker,
Ritcher, Quinn, and their successors. For so long as Tenant leases and occupies
the Premises pursuant to the provisions of this Lease, Landlord agrees not to
enter into any lease(s) for space in Newport Corporate Center with a Direct
Competitor. This prohibition shall not apply to assignments or subleases of
existing leases. In addition, commencing with the date Tenant exercises its
Expansion Right pursuant to Section 1.6 above with respect to the fifth (5th)
floor of the Building, and continuing for so long as Tenant leases and occupies
floors one (1) through five (5) of the Building pursuant to the terms of this
Lease, Landlord shall not, without Tenant's prior written consent, enter into a
lease with a software company for space in the Building.

2.  TERM

  2.1  Initial Term.  The term of this Lease shall be for a period of six and
       ------------
one-half (6.5) years, as extended as provided in Subsection 2.1(a) below if the
Commencement Date falls on a date other than the first of the month ("Initial
Term").  The Initial Term as well as the Tenant's obligation to pay Rent shall
commence on the date (but not prior to September 30, 1999, and

                                       8
<PAGE>

subject to the provisions of Subsection 2.1(e) below) of Substantial Completion
of Floors 1 through 4 of the Building (the "Commencement Date"); except that if,
after the execution of this Lease, Tenant's design decisions, revisions, or
additional work of Tenant or it's agents or architect delays Substantial
Completion, then to the extent such delay is determined to be caused by or
attributable to Tenant or its agents or architect, the Commencement Date which
would otherwise be established shall be accelerated to a new date by the number
of days of said delay. See Exhibit "C" attached hereto for further provisions
regarding Substantial Completion delay procedures.

     (a)  The terms and provisions of this Lease are effective as of the date of
this Lease. If the Commencement Date does not occur on the first day of the
month, then the Term shall be extended by the number of days remaining in that
fractional first month such that the Termination Date is the last day of a
month. In that event, however, the fractional month shall be added to the end of
the Initial Term for the purposes of determining Basic Rent under Section 3.1
below and Tenant shall pay Rent for the fractional first month on a per diem
basis (calculated on the basis of a thirty-day month) until the first day of the
month following the Commencement Date. Thereafter the Basic Rent, as well as the
Tenant's share of Operating Costs (defined herein) shall be paid in advance in
equal monthly installments on the first day of each and every month. Upon the
Commencement Date, the parties shall execute a written acknowledgment of this
Lease setting forth the precise Commencement Date and expiration date (the
"Expiration Date") of this Lease. Said acknowledgment shall be in the form
attached hereto as Exhibit "D". Failure to execute such acknowledgment, however,
shall not affect Landlord's or Tenant's liability hereunder.

     (b)  Early Possession.   If Landlord offers and Tenant chooses to occupy
          ----------------
the Premises and performs its regular business operations therein prior to the
Commencement Date set forth in Section 2.1, then the Commencement Date shall be
such date of such occupancy. Tenant's occupancy prior to the originally
scheduled Commencement Date shall be subject to all the provisions of this Lease
and shall not advance the Expiration Date. Tenant shall have the right of access
to the Premises prior to the Commencement Date as provided in Section 3.3.2 of
the Construction Agreement for Lease attached hereto as Exhibit "C" (the
"Construction Agreement").

     (c)  Landlord Delay.  If for any reason, other than a Tenant delay or a
          --------------
delay for any of the reasons stated in Section 31, Landlord cannot deliver
possession of the Premises to Tenant on or before October 15, 1999 (the
"Scheduled Substantial Completion Date"), then subject to the provisions of the
Construction Agreement relating to such delay, the following shall occur: (i)
the Commencement Date shall be the date of Substantial Completion, (ii) the
liquidated damages set forth in the Construction Agreement shall apply, (iii)
the Expiration Date shall be adjusted so that the length of the Term remains as
provided in Section 2.1 and (iv) Landlord and Tenant shall execute an amendment
to this Lease setting forth the adjusted Commencement Date and Expiration Date.

     (d)  Liquidated Damages and Termination Rights.  Anything in this Lease
          -----------------------------------------
to the contrary notwithstanding, the parties agree that the actual damages that
Tenant would suffer as a consequence of delays in Substantial Completion beyond
the Scheduled Substantial Completion Date are too difficult to quantify, and
that in the event of such a delay, not due to a

                                       9
<PAGE>

Tenant delay and not due to a delay for any of the reasons described in Section
31 below ("Force Majeure"), the following liquidated damages and remedial
actions are agreed by the parties:

       (i)  Liquidated Damages.  The liquidated damages provisions of Section
            ------------------
7.4 of the Construction Agreement shall apply.

       (ii) No Rent.  Until Substantial Completion occurs, no Rent is due
            -------
under this Lease.

       (iii)  Tenant's Right to Terminate. If Substantial Completion does not
              ---------------------------
occur on or by April 1, 2000, then Tenant may terminate this Lease and the
Amended and Restated Newport Terrace Lease (as defined in Section 36 below) by
notice to Landlord, which notice must be given on or before April 10, 2000, and
shall be effective April 30, 2000. If Tenant does not elect to terminate this
Lease and the Amended and Restated Newport Terrace Lease by giving notice
thereof by April 10, 2000, this Lease and the Amended and Restated Newport
Terrace Lease shall continue in full force and effect. If Tenant elects to
terminate, the provisions of subsection 2.1(d)(v) below shall be effective.

     (iv) Landlord's Right to Terminate.  If Substantial Completion does not
          -----------------------------
occur on or by July 1, 2000, due to delays beyond Landlord's control, then
Landlord may terminate this Lease and the Amended and Restated Newport Terrace
Lease by notice to Tenant, which notice must be given on or before July 10,
2000, and shall be effective July 30, 2000. If Landlord does not elect to
terminate this Lease and the Amended and Restated Newport Terrace Lease by
giving notice thereof by July 10, 2000, this Lease and the Amended and Restated
Newport Terrace Lease shall continue in full force and effect. If Landlord
elects to terminate, the provisions of subsection 2.1(d)(v) below shall be
effective.

    (v)  Effect of Termination.  If either Tenant terminates this Lease under
         ---------------------
subsection 2.1(d)(iii) above or Landlord terminates this Lease under subsection
2.1(d)(iv) above, then:

         (1)  All of the terms and conditions of the Newport Terrace Lease,
Newport Tower Lease, One Newport Lease and Two Newport Lease (as those terms are
defined in Section 36 below) shall remain in full force and effect as they
existed prior to this Lease and the Amendments (as defined in Section 36),
including the Amended and Restated Newport Terrace Lease, shall be null and
void;

         (2)  Tenant shall have the option to renew the Newport Tower Lease, One
Newport Lease and Two Newport Lease for a minimum of five (5) years at the end
of the existing terms in accordance with the terms and provisions of the
Amendments; and

         (3)  Tenant shall reimburse Landlord for the full Newport Terrace
Allowance (as defined in the Amended and Restated Newport Terrace Lease) or, in
the alternative, shall exercise its option to renew the Newport Terrace Lease
for five (5) years in accordance with the terms and provisions of the Newport
Terrace Lease provided, however, if Tenant renews the Newport Terrace Lease,
Landlord shall not be obligated to provide any allowance other than the Newport
Terrace Allowance.

                                      10
<PAGE>

       (e)  Interim Space. Landlord agrees to lease to Tenant approximately
            -------------
17,000 rentable square feet of space in Newport Tower in the location identified
on Exhibit "A-13" attached hereto (the "Interim Space") at the rate of $16.50
per square foot, triple net, commencing on or about April 1, 1999, and
continuing until the first to occur of Substantial Completion or the termination
of this Lease. Except with respect to the business terms, the lease agreement
for the Interim Space shall be based on the format and legal provisions of this
Lease. Landlord and Tenant shall use their reasonable best efforts to prepare a
mutually acceptable short term lease agreement within sixty (60) days after the
date of this Lease.

       (f)  Delay in Occupancy.  Notwithstanding the above provisions of this
            ------------------
Section 2.1 to the contrary, if Substantial Completion occurs between November
1, 1999 and December 31, 1999, Tenant may, by written notice to Landlord within
five (5) days of Substantial Completion, elect not to take occupancy of the
Premises until February 10, 2000, in which case the Commencement Date shall be
January 10, 2000; provided, however, if Substantial Completion occurs between
November 1, 1999 and December 31, 1999, Tenant may, by notice to Landlord at any
time between the date of Substantial Completion and January 10, 2000, elect to
occupy any portion of the Premises, in which case Tenant shall pay Rent on all
space which Tenant elects to occupy (as well as Rent on other space occupied by
Tenant in other buildings) and Basic Rent shall be paid at the per square foot
rate specified for Years 1 - 2 of the Lease Term in Section 3.1 below .

  2.2  Option to Extend. Landlord hereby grants to Tenant the right, privilege,
       -----------------
and option to extend the Term of this Lease for three (3) periods of five (5)
years ("First, Second and Third Extended Terms" respectively), from the date of
expiration of the Initial Term, upon the same terms and conditions as herein
contained, except Basic Rent. Basic Rent shall be determined in the method set
forth below for each Extended Term.  Tenant shall give written notice to
Landlord at least three hundred sixty (360) days prior to the expiration of the
then expiring Term of Tenant's intention to exercise said option.  In the event
that Tenant fails to give notice by the specified deadline of its intention to
exercise said option, then Tenant's right to extend this Lease for the remaining
available Extended Terms shall terminate and be of no further force and effect.

       (a)  If Tenant validly exercises its option to extend the Term of this
Lease as herein provided, Basic Rent shall be adjusted as of the first day of
the applicable Extended Terms as follows:

            (i)  Commencing within ten (10) days after Landlord's receipt of
Tenant's notice of its intention to exercise its option, Landlord and Tenant
shall attempt to agree upon Basic Rent for the Premises for the applicable
Extended Term, such rent to equal one hundred percent (100%) of the estimated
fair market rental value of the Premises for the applicable Extended Term. If
the parties are unable to agree upon the Basic Rent within thirty (30) days
after Landlord's receipt of the notice, then within thirty (30) days thereafter
each party, at its own cost and by giving notice to the other party, shall
appoint a real estate appraiser with at least five (5) years full-time
commercial real estate appraisal experience in the area in which the Premises
are located to appraise and set the Basic Rent for the applicable Extended Term.
If a party does not appoint an appraiser within ten (10) days after the other
party has given notice of

                                      11
<PAGE>

the name of its appraiser, the single appraiser appointed shall be the sole
appraiser and shall set Basic Rent for the applicable Extended Term. If each
party shall have so appointed an appraiser, the two appraisers shall meet
promptly and attempt to set the Basic Rent for the applicable Extended Term. If
the two appraisers are unable to agree within thirty (30) days after the second
appraiser has been appointed, they shall attempt to select a third appraiser
meeting the qualifications herein stated within ten (10) days after the last day
the two appraisers are given to set Basic Rent. If the two appraisers are unable
to agree on the third appraiser within such ten (10) day period, either of the
parties to this Lease, by giving five (5) days notice to the other party, may
apply to the then presiding judge of the Superior Court of King County for the
selection of a third appraiser meeting the qualifications stated in this
paragraph. Each of the parties shall bear one-half (1/2) of the cost of
appointing the third appraiser and of paying the third appraiser's fee. The
third appraiser, however selected, shall be a person who has not previously
acted in any capacity for either party.

            (ii)   Within thirty (30) days after the selection of the third
appraiser, a majority of the appraisers shall set Basic Rent for the applicable
Extended Term. If a majority of the appraisers are unable to agree upon the
Basic Rent within the stipulated period of time, the three appraisals shall be
added together and their total divided by three (3). The resulting quotient
shall be the Basic Rent for the Premises during the applicable Extended Term.
If, however, the low appraisal and/or the high appraisal is/are more than five
percent (5%) lower and/or higher than the middle appraisal, the low appraisal
and/or the high appraisal shall be disregarded. If only one (1) appraisal is
disregarded, the remaining two (2) appraisals shall be added together and their
total divided by two (2), and the resulting quotient shall be Basic Rent for the
Premises during the applicable Extended Term.

            (iii)  For purposes of determining the Basic Rent for an Extended
Term, including the determination of Basic Rent by the appraisers, the "fair
market rental value" shall be based on the actual rental rates which ready and
willing renewal tenants are paying as of the date of the notice of Tenant's
election to extend the Term, as annual rent for a primary renewal premises (as
distinguished from the rent payable for a sublet premises or with respect to an
assignment of an interest in an existing lease or for the initial term for newly
constructed or existing premises) to a ready and willing landlord of such
primary renewal premises for space comparable to the Premises in a building
comparable to the Building. Rental rates quoted or used under sublease
agreements shall be considered rates of special circumstances and shall be
excluded from the definition of "fair market rental value" under this Section.

            (iv)  Notwithstanding the above to the contrary, such arbitration
procedure shall be completed prior to the commencement date of the Extended Term
and shall be final, binding and non appealable.

       (b)  If Tenant timely and properly exercises an option to extend, then
Landlord agrees to provide Tenant with an allowance (the "Renewal Allowance")
with respect each option exercised for the actual cost to re-paint and re-carpet
the Premises (the "Renewal Improvements") in Building standard materials as
defined in the Building Standard Tenant Improvement Specifications attached
hereto as Exhibit "C-5". The Renewal Allowance shall be paid by Landlord to
Tenant within ten (10) days of completion of the Renewal Improvements and
receipt by Landlord of copies of paid invoices for the Renewal Improvements.

                                      12
<PAGE>

        (c)  The option to extend the Term in this Section is not assignable
separate and apart from this Lease, and may only be exercised by Tenant or its
assignee as permitted under Section 8 of this Lease.

        (d)  If Tenant timely and properly exercises its option to extend, then
Landlord and Tenant shall within fifteen (15) days after the determination of
Basic Rent for the Extended Term in question, execute an amendment to this Lease
extending the Term on the terms and conditions set forth in this Section 2.2.

       (e)  Tenant shall not have the right to exercise the option to extend,
notwithstanding anything to the contrary set forth above:

            (i)   During the time commencing from the date Landlord gives to
Tenant a written notice that Tenant is in material nonmonetary default under any
provisions of this Lease, and continuing until the default alleged in said
notice is cured; or

            (ii)  During the period of time commencing on the day that written
notice is given that a monetary obligation to Landlord is due from Tenant and
unpaid continuing until the obligation is paid.

       (f)  The period of time within which the option may be exercised shall
not be extended or enlarged by reason of Tenant's inability to exercise the
option because of the provisions and/or restrictions in Section 2.2(e).

       (g)  All rights of Tenant under the provisions of this option shall
terminate and be of no further force or effect even after Tenant's due and
timely exercise of the option, if after such exercise, but prior to the first
day of the Extended Term in question, (1) Tenant fails to pay to Landlord a
monetary obligation of Tenant for a period of five (5) business days after
written notice thereof from Landlord; or (2) Tenant fails to commence to cure a
default within thirty (30) days after the date Landlord, during the term of this
Lease, gives notice to Tenant of such default; provided, however, the time
periods set forth in this subsection shall be tolled during the time period
necessary to resolve any dispute if Tenant is, in good faith, contesting an
alleged default.

the percentage change in Basic Rent for the Extended Terms for the same period.

     3.2  Definition of Rent.  All amounts due from Tenant to Landlord under
          ------------------
this Lease other than Basic Rent shall be due as "Additional Rent." The terms
"Rent" and "Rental" as used in this Lease shall mean all amounts to be paid
hereunder by Tenant whether those sums are designated Basic Rent or Additional
Rent or otherwise and as adjusted by the terms of this Lease. Failure by Tenant
to pay any sum of Rent due under this Lease shall entitle Landlord to pursue any
or all remedies specified in this Lease as well as remedies specified in RCW
Chapter 59.12 or otherwise allowed by law, subject to Landlord giving Tenant
prior notice of such default and the expiration of any applicable cure period
without cure having been accomplished.

Landlord may designate from time to time by written notice to Tenant, without
demand and without deduction, setoff or counterclaim, except as otherwise
provided herein. If Landlord shall at any time or times accept said Rent after
it shall become due and payable, such acceptance shall not excuse delay upon
subsequent occasions, or constitute, or be construed as a waiver of any or all
of Landlord's rights hereunder. In the event Rent is not paid when it becomes
due, Tenant shall pay interest at the rate of two percent (2%) per annum above
the prime rate charged from time to time by Seafirst Bank on all late payments
past due.

                    improvements to benefit retail tenants in the Building.

  4.4  Operating Costs and Adjustment. Before the commencement of each calendar
       ------------------------------
year of the Lease term, or as soon thereafter as practicable, Landlord will
notify Tenant in writing of Landlord's good faith estimate of the Operating
Costs and Tenant's Percentage times said Operating Costs for the next succeeding
year (until the following January 1). Effective January 1 and each month
thereafter, Tenant shall pay to Landlord as Additional Rent one-twelfth (1/12th)
of Tenant's Percentage of said estimated Operating Costs.  On the next
succeeding January 1, or as soon thereafter as possible, but not later than the
next succeeding March 31, or upon sooner termination of the Lease, Landlord will
compute Tenant's total rental adjustment for such previous year or portion
thereof if applicable, based on the actual Operating Costs and, shall provide
Tenant with a written statement showing the actual Operating Costs and Tenant's
Percentage of said Operating Costs.  Such statement shall provide an itemized
breakdown of the actual Operating Costs.  If the total amount of Additional Rent
paid by Tenant for such previous year or portion thereof is less than Tenant's
Percentage of actual Operating Costs, then Tenant shall pay Landlord any
deficiency.  If the total amount paid by Tenant for such previous year or
portion thereof exceeds the Tenant's Percentage of actual Operating Costs, then
Landlord shall credit such excess to the payment of Rent and Additional Rent
which may thereafter become due.  Any adjustment payment required to be made
pursuant to this section shall be made within thirty (30) days after Landlord
has notified Tenant thereof.  Landlord shall make available for Tenant's review
and upon request by Tenant, the accounting information on which any Operating
Cost adjustment is based.  If this Lease commences at a time other than at the
commencement of a calendar year, or expires at a time other than the expiration
of the calendar year, Landlord shall estimate Tenant's contributions for that
portion of the calendar year contained in the Lease term and Tenant shall pay
such charge in equal monthly installments on the first day of those months of
that calendar year which are in the Lease term.  If at any time Landlord obtains
or receives additional information regarding the actual amounts of the
contributions, Landlord may, at its election, adjust the amount of the monthly
installments due during the balance of the calendar year of the Lease term to
reflect such additional information.

  Even though the term has expired and Tenant has vacated the Premises, when the
final determination is made of Tenant's Percentage of Operating Costs for the
year in which this Lease terminates Tenant shall within thirty (30) days pay any
increase due over the estimated expenses paid and, conversely, if Tenant has
otherwise complied with all other terms and conditions of this Lease, Landlord
shall refund any excess to Tenant within thirty (30) days following the date of
termination.

  Any increase in Tenant's Percentage of Operating Costs pursuant to this
Section shall be deemed Additional Rent payable by Tenant hereunder, and in the
event of nonpayment thereof, Landlord shall have similar rights with respect to
such nonpayment as it has with respect to any other nonpayment of Basic Rent
hereunder.

  4.5  Right to Audit.  Landlord agrees to keep books and records showing the
       --------------
Operating Costs in accordance with a system of accounts and accounting practices
consistently



                                      19
<PAGE>

maintained on a year-to-year basis. Tenant shall have the right to audit, at
Tenant's expense, Landlord's books and records pertaining to Operating Costs and
Real Property taxes. In the event that any such audit conducted in accordance
with generally accepted accounting principles, consistently applied, reveals a
discrepancy of five percent (5%) or more in Landlord's favor between Landlord's
statement of the actual operating and tax costs for the calendar year and the
amount of such operating and tax costs determined by such audit, then Landlord
shall reimburse to Tenant the excess amount, if any, paid by Tenant and shall
pay for the cost of such audit. Tenant's right to audit shall be limited to one
(1) time per calendar year. The time period covered by the audit shall be
limited to the previous twenty-four (24) months from the date of such audit.

  4.6  Credits/Reimbursements.  Operating Costs shall be reduced by
       ----------------------
reimbursements, credits, discounts, reductions, or other allowances received or
receivable by Landlord for items of cost included in Operating Costs.  If
Landlord receives a refund of any portion of real estate taxes that were
included in the real estate taxes paid by Tenant, then Landlord shall reimburse
Tenant its pro rata share of the refunded taxes, less any expenses that Landlord
reasonably incurred to obtain the refund.

5.  SECURITY DEPOSIT

    It is hereby agreed that no security deposit will be required.

6.  UTILITIES AND SERVICES

    6.1  Landlord's Duties.  Provided that Tenant is not in default or beyond
         -----------------
any applicable cure period, under any of the material terms, covenants,
conditions, provisions or agreements of this Lease, Landlord will provide the
following services:

         (a)  Maintain normal and usual Building business hours (the "Normal
Business Hours"), Monday through Friday, from 7:00 a.m. to 6:00 p.m. and on
Saturday from 8:00 a.m. to 1:00 p.m.; Sundays and holidays excepted.

         (b)  Furnish utilities to provide for lighting, convenience power, and
heat and air conditioning twenty-four (24) hours a day for the comfortable
occupancy of the Premises; provided, however, utilities used by Tenant during
other than the Normal Business Hours shall be billed to Tenant at the actual
hourly rate charged to Landlord. Tenant agrees to cooperate fully at all times
with Landlord, and to abide by all regulations and requirements which Landlord
may prescribe for the proper function and protection of said air conditioning
system. Tenant agrees not to connect any apparatus, device, conduit or pipe to
the Building chilled and hot water air conditioning supply lines. Tenant further
agrees that without prior Landlord notice and approval, neither Tenant nor its
servants, employees, agents, visitors, licensees or contractors shall at any
time enter mechanical installations or facilities of the Building or adjust,
tamper with, touch or otherwise in any manner affect said installations or
facilities. The cost of maintenance and service calls to adjust and regulate the
air conditioning system shall be charged to Tenant if the need for maintenance
work results from either Tenant's adjustment of room thermostats or Tenant's
failure to comply with its obligations under this Section. In the event Tenant
occupies the entire Building, Tenant shall have the right, upon notice to
Landlord,



                                      20
<PAGE>

to pay for Tenant's electricity directly to the utility provider so long as such
payments are made as and when due. Landlord agrees not to install or utilize its
own power plant for the Building without Tenant's prior written consent, which
consent may be withheld in Tenant's discretion. In addition, Landlord agrees not
to contract with an independent utility provider without Tenant's full
involvement and Tenant's prior written consent, which consent shall not be
unreasonably withheld, conditioned, or delayed, provided that it shall be
reasonable for Tenant to withhold consent if the proposed utility provider is
not a reputable quality utility provider, does not provide the services at
competitive market rates, and does not have local maintenance and emergency
response personnel.

         (c)  Provide Tenant twenty four (24) hours per day, seven (7) days per
week, fifty-two (52) weeks per year access to the Building and Premises without
the requirement of prior notice to Landlord. Landlord shall provide Tenant with
sufficient keys or access devices for Tenants employees and guests who will be
utilizing the Premises. The cost of such keys or access devices shall be drawn
from the Tenant Improvement Allowance. Landlord shall also provide security
services for the Building comparable as to coverage, control and responsiveness
(but not necessarily as to means for accomplishing same) to first class multi-
tenant (unless the Building is a single tenant building) office buildings in the
area in which the Building is located including, without limitation, electronic
security monitoring of all entrances and exits to the Building on a twenty-four
(24) hour per day basis; provided, however, Landlord shall have no
responsibility to prevent and Landlord shall not be liable to Tenant for any
liability or loss to Tenant, its agents, employees and visitors arising out of
losses due to theft, burglary, or damage or injury to persons or property caused
by persons gaining access to the Building and Premises unless caused by
Landlord's negligence. Tenant shall have the right to install an electronic
security system within the Premises, serving only the Premises, at its sole cost
and expense, provided, however, Landlord shall have the right to approve the
design, plans and specifications for such security systems and the installations
thereof.

         (d)  Provide non-attended passenger elevator facilities during all
working days (and on Saturday, Sunday and holidays provide at least one elevator
subject to call). Tenant acknowledges that the elevator cars will not be
equipped with card-key access devices.

         (e)  Provide janitorial and maintenance services to the Premises in
accordance with the Janitorial Services described in Exhibit "I" attached hereto
provided the Premises are kept in reasonable order by Tenant. Any and all
additional janitorial service desired by the Tenant shall be contracted for by
the Tenant directly with Landlord's janitorial agent and the cost and payment
thereof shall be and remain the sole responsibility of the Tenant. In addition,
Tenant may elect to contract directly with Landlord's janitorial agent for
normal janitorial and cleaning services for the Premises and may also elect to
replace the lights in the Premises at Tenant's cost.

         (f)  Make all repairs to the Premises, excluding repairs to or any
special treatment of walls, floors or ceilings made by or at the request of
Tenant and excluding repairs to any fixtures or other improvements installed or
made by or at the request of Tenant. In the event any repairs are required
because of any act or omission of Tenant, its agents, employees, customers, or
invitees, Landlord may make such repairs and add the cost thereof to the next
installment of Rent. Landlord shall proceed in a reasonable manner and with due
diligence in



                                      21
<PAGE>

performing all Landlord obligations hereunder which involve the delivery of
services and utilities to Tenant.

         (g)  Provide water for drinking, lavatory and toilet purposes drawn
through fixtures installed by Landlord.

         (h)  Repair and maintain the structural, foundational, window systems,
elevator, HVAC, electrical, plumbing and roof portions of the Building, along
with areas of ingress and egress at Landlord's sole cost except to the extent
such costs are "Operating Costs" as defined in Section 4.3(a) and except to the
extent that such costs are the obligation of Tenant under this Lease.

         (i)  Except with respect to matters related to Tenant's particular use
of the Premises, which shall be Tenant's responsibility, comply with the
provisions of the Americans with Disabilities Act (ADA) Title III, "Commercial
Facilities." Landlord reserves the right to object to and appeal any
determination that it must take any specific action to comply with the ADA;
provided Landlord will hold Tenant harmless from any adverse effects or cost of
such objection or appeal.

         (j)  Perform property management services in accordance with the
standards and terms set forth on Exhibit "J" attached hereto.

         (k)  Tenant shall have the right to have telecommunications services
provided to Tenant by a service provider other than US West (Landlord's initial
service provider) provided that Tenant pays all costs and expenses associated
with the connection of the new service provider to the Building and to the
Premises.

    6.2  Interruption.  It is understood that Landlord does not warrant that any
         -------------
of the services referred to above will be free from interruption by virtue of
strike or labor trouble or any other cause beyond Landlord's control.  Such
interruption of service shall not be deemed an eviction or disturbance of
Tenant's use or possession of the Premises, or any part thereof, nor shall it
render Landlord liable to Tenant for damages, by abatement or reduction of Rent
or otherwise, except as provided in Subsection 6.3 herein, nor shall it relieve
Tenant from performance of Tenant's obligations under this Lease, nor shall
Tenant be relieved from the performance of any covenant or agreement in this
Lease because of such failure or interruption.  Landlord reserves the right to
stop service of the elevator, plumbing, ventilation, air-conditioning, and
electrical systems, when necessary, by reason of accident or emergency, or, upon
reasonable advance notice to Tenant, for repairs, alterations or improvements,
which are in the reasonable judgment of Landlord necessary, until said repairs,
alterations or improvements shall have been completed.  Landlord shall use good
faith best efforts to minimize the disruption to Tenant's business in making
such repairs.

    6.3  Rent Abatement.  If there occurs an interruption or failure of services
         --------------
or utilities as referred to in Section 6.2 which is caused by Landlord's
negligence or other wrongful conduct or the negligence or wrongful conduct of
Landlord's agents, employees or contractors and Landlord fails to commence
within two (2) business days and thereafter diligently proceed to complete
repairs required to be made by Landlord under this Lease, and if the condition


                                      22
<PAGE>

referred to continues for a period of three (3) business days (or for more than
five (5) days in any ten (10) day period), then from the first day of the
existence of such condition (or the occurrence requiring repairs or
corrections), the Rent payable by Tenant hereunder (including Additional Rent)
shall be abated for the portion of the Premises for which normal and usual
utilization by Tenant is made impractical, such abatement to be effective for
the full period such condition exists and until the repairs or corrections are
made or the services or utilities are restored.

    6.4  Self-Help and Remedies.  If after written notice of the failure to
         ----------------------
perform is given to Landlord by Tenant; provided, however, that if any such
failure by Landlord to perform such service shall render the Premises
untenantable or unfit for Tenant's intended use then Tenant shall have the right
to take such reasonable actions as may be necessary to remedy the situation and
shall give Landlord contemporaneous notice of the actions it is taking.

    6.5  Cost of Services.  The cost of all services provided by Landlord under
         ----------------
this Section 6 shall be considered Operating Costs under Section 4; except for
Landlord's costs which are specifically set forth under Subsection 4.3(b) and
except for costs which are the responsibility of Tenant under this Lease.
Payment for all services rendered under this Section 6 shall be in accordance
with Section 4 of this Lease.

    6.6  Tenant's Rules and Regulations.  Landlord agrees to comply with the
         ------------------------------
"Tenant's Rules and Regulations" attached hereto as Exhibit K.
                                                    ---------

7.  CARE AND USE OF THE PREMISES

    7.1  Tenant's Duties.  Tenant agrees that it shall during the Term:
         ---------------

         (a)  Not use or occupy the Premises in violation of law or of the
certificate of occupancy issued for the Building, and shall, upon written notice
from Landlord, discontinue any use of the Premises which is declared by any
governmental authority having jurisdiction to be a violation of law or of said
certificate of occupancy. Tenant shall comply with any direction of any
governmental authority having jurisdiction which shall, by reason of the nature
of Tenant's use or occupancy of the Premises, impose any duty upon Tenant or
Landlord with respect to the Premises or with respect to the use or occupation
thereof.

         (b)  Give Landlord access to the Premises at all reasonable times, upon
reasonable advance notice to Tenant (which notice shall be directed to Tenant's
"Facilities Department" in addition to any other person to whom notices are
required to be given under this Lease), without charge or diminution of Rent, to
enable Landlord to examine the same and to make such repairs, additions and
alterations as are required under the terms of this Lease, including the right
to show the Premises for the purpose of a potential sale or lease. If Tenant
fails to respond to Landlord's request for access within one (1) business day,
Tenant shall be deemed to have agreed to the time and manner of Landlord's
requested access. If Landlord proposes to show the Premises, Tenant will be
allowed to limit or prevent access to those portions of the Premises Tenant
deems, in its sole business judgment, sensitive or confidential. Furthermore, if
Landlord proposes to show the Premises to a prospective Tenant, Landlord may be
precluded from doing so, except during the last six (6) months of the Lease
term.



                                      23
<PAGE>

         (c)  Keep the Premises in good order and condition, reasonable wear and
tear and casualty damage excepted, and replace all broken glass with glass of
the same quality as that broken, save only glass broken by fire and extended
coverage type risks.

         (d)  Recognize that improvements attached to the Premises become the
property of the Building and may not be removed without approval of Landlord
which approval may be subject to the Tenant's paying for the cost of repairs
resulting from the removal of such improvements.

         (e)  Upon the termination of this Lease in any manner whatsoever,
remove Tenant's property and those of any other person claiming under Tenant,
and quit and deliver up the Premises to Landlord peaceably and quietly in as
good order and condition as the same are in on the Commencement Date, reasonable
use and wear thereof, casualty damage and permitted alterations and additions
not specifically required to be removed upon termination of the Lease as they
were added excepted. The foregoing property required to be removed that is not
removed by Tenant at the termination of this Lease, however terminated, shall be
considered abandoned and Landlord may dispose of the same in the manner it deems
expedient with reasonable cost to be billed to the Tenant.

         (f)  Not place signs on the outside of the Premises or in places
visible from the outside by the public, without the prior written consent of
Landlord and subject to all applicable governmental rules and restrictions, as
well as the "Building Rules and Regulations as set forth in Exhibit "E".

         (g)  Not use or allow the Premises to be used for any unlawful purpose,
nor cause, maintain or permit any nuisance in, on or about the Premises. Tenant
shall not commit or suffer to be committed any waste in or upon the Premises.

         (h)  Not do or permit to be done anything which will invalidate or
increase the cost of any fire, extended coverage or any other insurance policy
covering the Building and/or property located therein unless Tenant agrees,
after Landlord gives thirty (30) days prior written notice to Tenant of the cost
thereof, to reimburse Landlord for any increase in the cost of such insurance
and subject to lender's approval. Tenant shall promptly, upon demand, reimburse
Landlord for any additional premium charges for such policy by reason of
Tenant's failure to comply with the provisions of this Section.

         (i)  Observe the "Building Rules and Regulations" described in Exhibit
"E", and which may be modified by Landlord from time to time provided Tenant is
given at least ten (10) business days prior written notice of such now or
amended rules and provided further that such new or amended rules do not
materially interfere with the terms and conditions of this Lease or unreasonably
interfere with Tenant's quiet enjoyment and its intended use of the Real
Property, the Building or the Premises or materially increase Tenant's cost of
operations or occupying the Premises and, provided further, that the Building
Rules and Regulations shall not discriminate against Tenant and are enforced by
Landlord in a non-discriminatory manner.



                                      24
<PAGE>

       (j)  Notify Landlord in writing promptly upon Tenant's discovery of any
latent defects in the Building and/or the Premises. So long as Tenant has
promptly notified Landlord in writing of any latent defect(s) (of which Tenant
has knowledge) in the building shell construction and the Tenant Improvements
owned by Landlord, then Tenant shall not be responsible for the costs and
expense of repairing latent defect(s) in the building shell construction and the
tenant improvements owned by Landlord. Provided, if Tenant fails to notify
Landlord of a latent defect of which Tenant has knowledge, then the failure to
notify Landlord must be a proximate cause of Landlord's damage before Tenant
would be responsible for the costs and expenses to repair such latent defect(s).

     7.2  Use of Rooftop.  The parties anticipate that Tenant will require
          --------------
rooftop installation of one or more of the following: (a) satellite dish; (b)
microwave dish; and (c) communications equipment. The installation of such
equipment shall be in accordance with Landlord's Rooftop Agreement attached
hereto as Exhibit "G".

     7.3  Maintenance of Link.  Except with respect to construction defects,
          -------------------
which shall be the obligation of Landlord, Tenant shall be solely responsible,
at Tenant's expense, for the cost of maintaining and repairing the Link. In the
event Tenant elects to have Landlord maintain and repair the Link, such
maintenance and repair shall be done at Tenant's cost and Tenant shall pay
Landlord a fee equal to 3.5% of such reasonable maintenance and repair costs.

7A.  HAZARDOUS MATERIALS

     7A.1  Tenant Representations.  Tenant represents and warrants that it shall
           ----------------------
not generate, treat, store or discharge on or at the Premises, the Building or
the Real Property any hazardous wastes or hazardous substances as defined in
applicable federal, state and/or local statutes or regulations; provided, Tenant
shall not be in violation of the foregoing by its use and storage of standard
office products, otherwise defined as hazardous, which products are used by
Tenant with due care and in accordance with the instructions of the product
manufacturer in the reasonable and prudent conduct of Tenant's business on the
Premises, and/or by Tenant's generation of a byproduct connected with its
permissible uses, which byproduct is otherwise defined as hazardous, so long as
Tenant uses due care in connection therewith.

     7A.2  Landlord Representations.  Landlord represents and warrants the
           ------------------------
following:

           (a)  To the best of Landlord's knowledge, there exists no
environmental liability from hazardous substances or toxic materials as defined
by the Comprehensive Environmental Response, Compensation and Liability Act of
1980 ("CERCLA"), 42 U.S.C. (S) 9601, et seq., and amendments thereto, or
                                     ------
hazardous waste as defined by the Resource Conservation Recovery Act ("RCRA"),
42 U.S.C. (S) 6901, 21 et seq., and amendments thereto, or
                       ------
hazardous waste or substance as defined in any federal, state or local law,
statute or regulation within, on, in, or under any portion of the Premises, the
Building, or the Real Property. Landlord further warrants and represents that,
to the best of Landlord's knowledge, no hazardous substances have been dumped,
stored or manufactured on or are now being stored or manufactured on the
Premises, the Building, or the Real Property. Landlord will not in the future
generate, treat, store or discharge such hazardous wastes or substances on or at
the

                                      25
<PAGE>

Premises, Building, or Real Property except in accordance with applicable
federal state and/or local statutes or regulations;

           (b) The Premises and Building will be free from asbestos; and

           (c)  Landlord will not knowingly allow another tenant or Landlord's
contractors to generate, treat, store or discharge hazardous wastes or hazardous
substances on or at the Premises, Building, or Real Property except in
accordance with applicable federal, state and/or local statutes or regulations.

8.   ASSIGNMENT AND SUBLETTING

     8.1  Except as allowed by the provisions of this Section 8, Tenant shall
not, either voluntarily or by operation of law, assign, hypothecate or transfer
this Lease, or sublet the Premises or any part thereof, without the prior
written consent of Landlord in each instance, which shall not be unreasonably
withheld, conditioned or delayed.

     8.2  In the event Tenant desires to assign, hypothecate or otherwise
transfer this Lease or sublet the Premises, then at least thirty (30) days prior
to the date when Tenant desires the assignment or sublease to be effective (the
"Assignment Date"), Tenant shall give Landlord a notice (the "Assignment
Notice"), which shall set forth the name, address and business of the proposed
assignee or sublessee, information (including references) concerning the
character, ownership, and financial condition of the proposed assignee or
sublessee, the Assignment Date, any ownership or commercial relationship between
Tenant and the proposed assignee or sublessee, and the consideration and all
other material terms and conditions of the proposed assignment or sublease, all
in such detail as Landlord shall reasonably require.

     8.3  The subletting of substantially all of the Premises for all or any
part of the remaining term of this Lease shall be deemed an assignment rather
than a sublease for purposes of this clause. Notwithstanding the foregoing,
Landlord shall consent to the assignment or transfer, if the Assignment Notice
states that Tenant desires to assign the Lease to any entity into which Tenant
is merged, that controls, is controlled by or is under common control with
Tenant, or with which Tenant is consolidated or which acquired all or
substantially all of the assets of Tenant, provided that the assignee first
executes, acknowledges and delivers to Landlord an agreement whereby the
assignee agrees to be bound by all of the covenants and agreements in this Lease
which Tenant has agreed to keep, observe or perform, that the assignee agrees
that the provisions of this Section shall be binding upon it as if it were the
original Tenant hereunder and that the assignee shall have a net worth
(determined in accordance with generally accepted accounting principals
consistently applied) immediately after such assignment which is at least equal
to the net worth (as so determined) of Tenant immediately prior to the
assignment.

  8.4  If Tenant shall sublet all or any portion of the Premises, any
consideration paid by the sublessee for the portion of the Premises being sublet
that exceeds one hundred percent (100%) of the Basic Rent and Rental Adjustments
provided by this Lease for such portion of the Premises being sublet shall be
due, owing and payable from Tenant to Landlord when owing by the sublessee under
the sublease; provided, however, that Tenant may retain out of

                                      26
<PAGE>

such excess rent an amount sufficient to reimburse Tenant for Tenant's actual
and reasonable out-of-pocket costs associated with the sublease (such as
commissions and allowances) not to exceed $5.00 per rentable square foot of
subleased space.

     8.5  Any sale, assignment, hypothecation or transfer of this Lease or
subletting of the Premises that is not in compliance with the provisions of this
Section 8 shall be void.  The consent by Landlord to any assignment or
subletting shall not be construed as relieving Tenant or any assignee of this
Lease or sublessee of the Premises from obtaining the express written consent of
Landlord to any further assignment or subletting, or as releasing Tenant or any
assignee or sublessee of Tenant from any liability or obligation hereunder
whether or not then accrued.  In the event Landlord shall consent to any
assignment or sublease, Tenant shall pay Landlord as Additional Rent a
reasonable attorneys and administrative fee for costs incurred in connection
with evaluating the Assignment Notice up to a limit of $500.  This Section 8
shall be fully applicable to all further sales, hypothecations, transfers,
assignments and subleases of any portion of the Premises by any successors or
assignee of Tenant, or any sublessee of the Premises.

     8.6  The term "assign," as used herein, shall include (i) an assignment of
a part of interest in this Lease, as well as any assignment from one cotenant to
another; and (ii) an assignment to any prior owner of the Tenant's interest
herein or part thereof.

     8.7  An assignment requiring consent within the meaning of this Section,
shall be deemed to include one or more sales or transfers, by operation of law
or otherwise, or creation of new stock, by which an aggregate of more than fifty
percent (50%) of Tenant's stock shall be vested in a party or parties who are
nonstockholders as of the date hereof. This Section 8.7 shall not apply and
consent shall not be required if Tenant's stock is listed on a recognized
security exchange. This paragraph shall not apply and consent shall not be
required if the stock is transferred:(i) for bona fide estate planning purposes
or due to the death of any member(s) of the family of Frank Pritt; (ii) to
Welsh, Carson, Anderson & Stowe, or any entity in which Frank Pritt or his
family members own at least fifty percent (50%) of the beneficial interest
therein, provided, the net worth (determined by generally accepted accounting
principles, consistently applied) of any such entity together with the net worth
of Tenant (as so determined) at the time of such transfer shall be equal to or
greater than the net worth of Tenant immediately prior to the transfer;
provided, the assignee will agree to be bound by all of the covenants and
agreements of this Lease which Tenant has agreed to keep, observe or perform and
the assignee will execute such documents as Landlord or its lender shall
reasonably require or request to evidence such agreement.

     8.8  Notwithstanding any provision of this Section 8 to the contrary, after
Landlord receives a request from Tenant to consent to either an assignment or
sublease, Landlord shall have the option, to be exercised by written notice
within thirty (30) days after the receipt of such request, to terminate this
Lease (in the case of an assignment or sublease of all of the Premises) or
recapture a portion of the Premises (in the case of a sublease of part of the
Premises) within such thirty (30) day period by notice to the Tenant.  If
Landlord elects to terminate this Lease or recapture a portion of the Premises,
Tenant shall have the right, to be exercised by written notice to the Landlord
within ten (10) days after receipt of such notice of termination or recapture
from Landlord, to withdraw its request for consent to the proposed

                                      27
<PAGE>

assignment or sublease, in which case the Tenant shall not proceed with the
proposed assignment or sublease, Landlord notice of termination or recapture
shall be null and void and this Lease shall continue in full force and effect in
accordance with its terms. Notwithstanding the above provisions of this Section
8.8 to the contrary, Landlord shall not have the right to recapture a portion of
the Premises with respect to the first 45,000 rentable square feet of space
subleased by Tenant and, if Tenant exercises its Expansion Right under Section
1.6 above with respect to both the fifth (5th) and sixth (6th) floors of the
Building, then Landlord shall not have the right to recapture with respect to
the amount of rentable square feet of space which equals the total rentable
square footage of the largest two floors in the Building subleased by Tenant
(which 45,000 square feet or two floor square footage, as applicable, is
hereafter referred to as the "Sublease Limit"). Once the Sublease Limit is
reached, Landlord shall have the right to recapture space in excess of the
Sublease Limit in accordance with the timing and other terms set forth above in
this Section. In addition, if Landlord does not elect to recapture space in
excess of the Sublease Limit prior to a sublease being entered into by Tenant,
Landlord shall have the right to recapture such space at the expiration of the
sublease term if Tenant does not re-occupy the space within ninety (90) days
after the expiration of the sublease term. With respect to Tenant's options to
extend under Section 2.2, Landlord agrees to respond to Tenant's request to
include any of such options in a proposed sublease at the time of Tenant's
request for consent. Further, in the event Tenant requests Landlord's consent to
a sublease to a single subtenant which covers a portion of the Premises in
excess of the Sublease Limit in addition to the Sublease Limit, and Tenant
desires to include Tenant's options to extend in the sublease terms, Landlord
agrees not to unreasonably withhold its consent to such request provided that
the proposed subtenant is of a quality comparable to other office tenants in the
Newport Corporate Center.

9.   INTENTIONALLY DELETED

10.  DAMAGE OR DESTRUCTION

     10.1  In the event the Building and/or the Premises is damaged by fire or
other perils covered by Landlord's insurance, Landlord shall:

           (a)  In the event of a partial destruction of the Building and/or the
Premises, to an extent not exceeding fifty percent (50%) of the full insurable
value thereof, and if the damage thereto is such that the Building and/or the
Premises may be repaired, reconstructed or restored within a period of one
hundred twenty (120) days from the date of the happening of such casualty and if
Landlord will receive insurance proceeds sufficient to cover the cost of such
repairs, then Landlord shall commence and proceed diligently with the work of
repair, reconstruction and restoration and this Lease shall continue in full
force and effect.

           (b)  If such repair, reconstruction, and restoration shall require a
period longer than one hundred twenty (120) days or exceeds fifty percent (50%)
of the full insurable value thereof, or if said insurance proceeds will not be
sufficient to cover the cost of such repairs, then Landlord either may elect to
so repair, reconstruct or restore and the Lease shall continue in full force and
effect or Landlord may elect not to repair, reconstruct, or restore and the
Lease shall then terminate. Under any of the conditions of this Section 10.1(b),
Landlord shall give written notice to Tenant of its intention within ninety (90)
days after the occurrence

                                      28
<PAGE>

of such damage or destruction. In the event Landlord elects not to restore the
Building and/or the Premises, this Lease shall be deemed to have terminated as
of the date of such partial destruction.

           (c)  If the Newport Terrace Building continues to be leased by Tenant
following any destruction of the Building and there remains at least eleven (11)
months on the term of this Lease and Tenant has exercised an option to extend,
and Tenant requests within thirty (30) days of the date of destruction, Landlord
shall rebuild the Building and Tenant Improvements regardless of the degree of
damage or time required to rebuild, provided Tenant agrees to pay any costs not
reimbursed by insurance and such payment is made to Landlord prior to the
commencement of construction.

           (d)  Notwithstanding the foregoing provisions of this Section 10.1,
if the parties are unable to agree on the extent of damage or whether or not the
damage can be repaired within any applicable time limits within ten (10) days
after Landlord's notice to Tenant of its election, then the dispute resolution
procedures of Section 17.6 shall be used to resolve the issue.

     10.2. Upon any termination of this Lease under any of the provisions of
this Section 10, the parties shall be released without further obligation to the
other from the date possession of the Premises is surrendered to Landlord except
for items which have therefore accrued and are then unpaid or any items which
have been prepaid by Tenant and a refund shall be then due.

     10.3  In the event of repair, reconstruction, and restoration by Landlord
as herein provided, the Rent payable under this Lease shall be abated
proportionately with the degree to which Tenant's use of the Premises is
impaired during the period of such repair, reconstruction or restoration unless
the damage or destruction was caused by the negligence or willful misconduct of
Tenant in which event the Rent payable hereunder will continue unabated. Tenant
shall not be entitled to any compensation or damages for loss in the use of the
whole or any part of the Premises and/or any inconvenience or annoyance
occasioned by such damage, repair, reconstruction or restoration, unless cause
in whole or in part by Landlord's negligence or willful misconduct.

     10.4  Tenant shall not be released from any of its obligations under this
Lease except to the extent and upon the conditions expressly stated in this
Section 10.  Notwithstanding anything to the contrary contained in this Section
10, if Landlord is delayed or prevented from repairing or restoring the damaged
Premises within twelve (12) months after the occurrence of such damage or
destruction by reason of acts of God, war, governmental restrictions, inability
to procure the necessary labor or materials, or other cause beyond the control
of Landlord, Landlord shall be relieved of its obligation to make such repair or
restoration and Tenant shall be released from its obligations under this Lease
as of the end of said one (1) year period and this Lease shall be deemed
terminated.

     10.5  If Landlord is obligated to or elects to repair or restore as herein
provided, Landlord shall be obligated to make repair or restoration only of
those portions of the Building and/or the Premises and/or Tenant Improvements
which were originally provided at Landlord's

                                      29
<PAGE>

expense, and the repair and restoration of items not provided at Landlord's
expense shall be the obligation of Tenant.

     10.6  Notwithstanding anything to the contrary contained in this Section
10, if any damage or destruction is due to any cause other than a cause covered
by the insurance required to be carried by Landlord under this Lease and such
damage or destruction will cost in excess of ten percent (10%) of the then
current full replacement cost of the Building, Landlord may elect to terminate
this Lease by giving notice thereof to Tenant provided, however, if Landlord
elects to terminate this Lease, Tenant shall have the right to cause Landlord to
repair such damage if, within twenty (20) days of receipt of Landlord's notice
of termination, Tenant agrees to pay for the repair cost in excess of such ten
percent (10%) and provides Landlord with reasonably adequate assurances of
Tenant's ability to pay for such excess cost.

     10.7  Notwithstanding anything to the contrary contained in this Section
10, Landlord shall not have any obligation whatsoever to repair, reconstruct or
restore the Premise when the damage resulting from any casualty covered under
this Section 10 occurs during the last twelve (12) months of the then current
term of this Lease. However, if Landlord chooses not to restore, Tenant may
elect to terminate this Lease.

11.  INDEMNIFICATION

     11.1  Indemnity by Tenant.  Tenant shall indemnify, defend and hold
           -------------------
Landlord harmless from all claims arising from Tenant's use of the Real
Property, Building and Premises or the conduct of its business or from any

Lease, or arising from any act, neglect, fault or omission of Tenant or of its
agents, contractors or employees, and from and against all costs, reasonable
attorneys' fees, expenses, and liabilities incurred in or about such claim or
any action or proceeding brought thereon. In case any action or proceeding shall
be brought against Landlord by reason of any such claim, Tenant, upon notice
from Landlord, shall defend the same at Tenant's expense; provided that the
foregoing provision shall not be construed to make Tenant responsible for loss,
damage, liability or expense resulting from injuries to third parties caused by
the negligence of Landlord, or its officers, contractors, agents or employees.

expense resulting from injuries to third parties caused by the negligence of
Tenant, or its officers, contractors, agents or employees.

     11.3  Limitation.  Notwithstanding anything contained above in this
           ----------
Section, in the event of concurrent negligence of Tenant, its agents, employees
or contractors, on the one hand, and that of Landlord, its agents, employees, or
contractors on the other hand, which concurrent negligence results in injury or
damage to persons or property, Tenant's obligation to indemnify Landlord and
Landlord's obligation to indemnify Tenant as set forth in this Section shall be
limited to the extent of the defaulting party's negligence, and that of its
agents, employees, or contractors, including the defaulting party's proportional
share of costs, attorneys fees and expenses incurred in connection with any
claim, action or proceeding brought with respect to such injury or damage.

                                      32
<PAGE>

Tenant and Landlord agree to mutually release each other from liability, and to
waive all right of recovery against the other, for any loss of or damage to the
property of each, including earnings derived there from caused by or resulting
from fire, the perils of the commonly referred to special form coverage and
leakage from automatic sprinkler systems, if any, or from perils insured against
under any insurance policies maintained by the parties hereto, regardless of the
cause of such loss or damage even though it results from some act or negligence
of a party hereto, its agents or representatives; provided, however, that this
provision shall be inapplicable if it should have the effect, but only to the
extent that it would have the effect, of invalidating any insurance coverage of
the parties thereto.

15.  EMINENT DOMAIN

     15.1  If all of the Premises, access to the Premises, or such portion of
the Premises or the Newport Corporate Center or access thereto as would, in
Landlord's or Tenant's reasonable judgment, materially interfere with the
continuation of Tenant's business operations in substantially the same manner
and space, shall be permanently taken or condemned for any public purpose, then
this Lease, at the option of Tenant or Landlord upon the giving of written
notice to the other party, shall forthwith cease and terminate upon the date
when title vests in the condemning or taking entity. If this Lease is terminated
as provided above, then this Lease shall cease and expire as if the date of
transfer of possession of the Premises, the Newport Corporate Center, or any
portion thereof, was the Expiration Date of this Lease.

     15.2  In the event that this Lease is not terminated by either Landlord or
Tenant under the prior Section, Tenant shall pay Rent up to the date of transfer
of possession of such portion of the Premises so taken or condemned and this
Lease shall thereupon cease and terminate with respect to such portion of the
Premises so taken or condemned as if the date of transfer of possession of the
Premises was the Expiration Date of the term of this Lease relating to such
portion of the Premises.  Thereafter the Rent shall be adjusted on a pro rata,
net rentable square foot basis.

     15.3  In the event of any such condemnation or taking and this Lease is not
so terminated, Landlord shall promptly repair the Premises or the Newport
Corporate Center, as the case may be, to the condition that existed at the
Commencement Date, so that the remaining portion of the Premises or Newport
Corporate Center, as the case may be, shall constitute a complete architectural
unit, fit for Tenant's occupancy and business; provided, however, that
Landlord's obligation to repair hereunder shall be limited to the extent of the
net proceeds made available to Landlord for such repair from any such
condemnation or taking. Landlord shall promptly make available to Tenant any and
all net proceeds made available to Landlord from such condemnation or taking to
the extent such proceeds are attributable to Tenant Improvements owned by and/or
paid for by Tenant and are not used in repairing or restoring such Tenant
Improvements to the condition that existed at the Commencement Date.

     15.4  In the event of any temporary taking or condemnation for any public
purpose of the Premises or any portion thereof, then this Lease shall continue
in full force and effect except that Rent shall be adjusted on a pro rata net
rentable square foot basis for the period of time that the Premises are so taken
as of the date of transfer of possession of the Premises, and Landlord shall be
under no obligation to make any repairs or alterations.

                                      33
<PAGE>

     15.5  In the event of any condemnation or taking of the Premises, Tenant
hereby assigns to Landlord the value of all or any portion of the unexpired term
of the Lease and all Tenant Improvements and Tenant may not assert a claim for a
condemnation award therefor; provided, however, Tenant may pursue a separate
attempt to recover an award or compensation against or from the condemning
authority for (i) the value of any fixtures, furniture, furnishings, and other
personal property which were condemned but which under the terms of this Lease
Tenant is permitted to remove at the end of the Term, (ii) the unamortized cost
of Tenant Improvements, which are not so removable by Tenant at the end of the
term of this Lease but which were installed solely at Tenant's expense, (iii)
relocation and moving expenses, and (iv) compensation for loss to Tenant's
business.

     15.6  Subject to Section 15.5, Landlord shall have the exclusive authority
to grant possession and use to the condemning authority and to negotiate and
settle all issues of just compensation or, in the alternative, to conduct
litigation concerning such issues; provided, however, that Landlord shall keep
Tenant informed of the proceedings and negotiations concerning the Premises.

16.  BANKRUPTCY

If Tenant shall file a petition in bankruptcy under any provision of the
Bankruptcy Code as then in effect, or if Tenant shall be adjudicated a bankrupt
in involuntary bankruptcy proceedings and such adjudication shall not have been
vacated within ninety (90) days from the date thereof, or if a receiver or
trustee shall be appointed of Tenant's property and the order appointing such
receiver or trustee shall not be set aside or vacated within ninety (90) days
after the end thereof, or if Tenant shall assign Tenant's estate or effects for
the benefit of creditors, or if this Lease shall, by operation of law or
otherwise, pass to any person or persons other than Tenant, then in any such
event Landlord may terminate this Lease, if Landlord so elects, with notice of
such election and with or without entry or action by Landlord.  In such case,
notwithstanding any other provisions of this Lease, Landlord, in addition to any
and all rights and remedies allowed by law or equity, shall, upon such
termination, be entitled to recover damages in the amount provided in Section
17.2 hereof.  Neither Tenant nor any person claiming through or under Tenant or
by virtue of any statute or order of any court shall be entitled to possession
of the Premises but shall surrender the Premises to Landlord.  Nothing contained
herein shall limit or prejudice the right of Landlord to recover damages by
reason of any such termination equal to the maximum allowed by any statute or
rule of law in effect at the time when, and governing the proceedings in which,
such damages are to be provided; whether or not such amount is greater, equal
to, or less than the amount of damages recoverable under the provisions of this
Section.

17.  DEFAULT AND RE-ENTRY: REMEDIES

     17.1 Default.  The occurrence of any one or more of the following events
          -------
shall constitute a default hereunder by the party acting or failing to act:

                                      34
<PAGE>

          (a)  The failure to make any payment required by this Lease as and
when due, where such failure shall continue after three (3) days' written notice
that the same was not paid when due.

          (b)  The failure to observe or perform any of the express or implied
covenants or provisions of this Lease to be observed or performed by Tenant,
other than as specified in Section 17.1(a) above, where such failure shall
continue for a period of fifteen (15) days after written notice thereof from the
other party. If the nature of the default is such that more than fifteen (15)
days are reasonably required for its cure, then no default shall occur if the
party shall commence such cure within said fifteen (15) day period and
thereafter diligently prosecute such cure to completion. Notwithstanding the
above to the contrary, Tenant may contest mechanic liens and other claims
against the Building and/or Premises made by third parties without being in
default so long as it takes reasonably adequate steps to protect the Landlord's
interest.

          (c)  Subject to Section 365(b)(2) and (e)(1), Bankruptcy Reform Act of
1978, as amended by the Bankruptcy Amendments and Federal Judgeship Act of 1984,
(a) The making of any general assignment for the benefit of creditors; (b) the
filing by or against a party a petition to have that party adjudged a bankrupt
or a petition for reorganization or arrangement under any law relating to
bankruptcy (unless, in the case of a petition filed against a party, the same is
dismissed within thirty (30) days); (c) the appointment of a trustee or receiver
to take possession of substantially all of a party's assets located at the
Premises or of that party's interest in this Lease, where possession is not
restored within one hundred twenty (120) days; or (d) the attachment, execution
or other judicial seizure of substantially all of a party's assets located at
the Premises or of that party's interest in this Lease where such seizure is not
discharged within one hundred twenty (120) days.

     17.2  Remedies on Default.  In the event of any such default by Tenant,
           -------------------
then Landlord may elect either (a) to cancel and terminate this Lease, (b) to
terminate Tenant's right to possession only without terminating the Lease, or
(c) pursue any other remedy available at law or equity.

In the event of election under 17.2(b) above to terminate Tenant's right to
possession only, Landlord may, at Landlord's option, enter into the Premises,
change the locks and take and hold possession of the Premises in accordance with
applicable law, without such entry into possession terminating this Lease or
releasing Tenant in whole or in part from Tenant's obligation to pay the Rent
hereunder for the full stated term.  Upon such re-entry, Landlord may remove all
persons and property from the Premises, and such property may be removed and
stored in a public warehouse or elsewhere at the cost of and for the account of
Tenant.  No re-entry or taking possession of the Premises by Landlord pursuant
to this Section shall be construed as an election to terminate this Lease unless
a written notice of such intention is given to Tenant or unless the termination
thereof is decreed by a court of competent jurisdiction.  Upon and after entry
into possession without termination of the Lease, Landlord shall use good faith
best efforts to relet the Premises, or any part thereof, for the account of
Tenant, to any person, firm or corporation, other than Tenant, for such rent,
for such time and upon such terms as Landlord, using reasonable discretion,
shall determine, subject to Landlord's legal duty to mitigate its damages and
re-let the Premises, but Landlord shall not be

                                      35
<PAGE>

required to accept any tenant offered by Tenant or to observe any instruction
given by Tenant about such reletting. In any such case, Landlord may make
repairs and redecorate the Premises to the extent reasonably necessary to secure
a replacement tenant, and Tenant shall, upon demand, pay the costs thereof,
together with all of Landlord's reasonable expenses of reletting. If the
consideration collected by Landlord upon any such reletting for Tenant's
account, and after deducting all expenses incident thereto, including reasonable
brokerage fees and legal expenses, is not sufficient to pay monthly the full
amount of the Rent provided in this Lease, Tenant shall pay to Landlord the
amount of each monthly deficiency upon demand. In the event that Landlord shall
have terminated Tenant's right to possession only, Landlord shall have the right
to further pursue any remedy at law or in equity that may be available to
Landlord.

     17.3 Rent After Termination.  In the event Tenant ceases to conduct its
          -----------------------
business operations on the Premises or, if Landlord shall at any time be
entitled to Rent under this Lease pursuant to any of the covenants, conditions
or agreements of this Lease either (1) after termination of Tenant's right to
possession without termination of this Lease, or (2) after the termination of
this Lease, then Landlord shall recover and Tenant agrees to pay the Basic Rent
and any Additional Rent, together with late fees and interest, as provided in
this Lease.  In the event that Landlord shall elect to terminate this Lease then
upon such termination Tenant shall (if it has not already done so) quit and
surrender the Premises to Landlord and Landlord may recover from Tenant:

          (a) Any unpaid Rent which had been earned at the time of such
termination; plus

          (b)  The unpaid Rent which would have been earned after termination
until the time of award exceeds the amount of such Rent loss that Tenant proves
could have been reasonably avoided; plus

          (c)  The present value at the time of award of the amount by which the
unpaid Rent for the balance of the term after the time of award exceeds the
amount of such Rent loss that Tenant proves could be reasonably avoided; plus

          (d)  Any other amount necessary to compensate Landlord for all the
damage proximately caused by Tenant's failure to perform Tenant's obligations
under this Lease or which in the ordinary course of things would be likely to
result therefrom.

     17.4 Cumulative Remedies; No Waiver.  Except as otherwise provided in this
          -------------------------------
Lease, all rights, options and remedies of either party contained in this Lease
shall be construed and held to be cumulative, and no one of them shall be
exclusive of the other, and Landlord or Tenant shall have the right to pursue
any one or all of such remedies or any other remedy or relief which may be
provided by law, whether or not stated in this Lease.  No waiver of any default
of Tenant or Landlord hereunder shall be implied from any acceptance by Landlord
or Tenant of any Rent or other payments due hereunder or any omission by
Landlord or Tenant to take any action on account of such default if such default
persists or is repeated, and no express waiver shall affect defaults other than
as specified in said waiver.  The consent or approval of Landlord or Tenant to
or of any act by the other requiring the other's consent or approval shall

                                      36
<PAGE>

not be deemed to waive or render unnecessary Landlord's or Tenant's consent or
approval to or of any subsequent similar acts by Tenant or Landlord.

     17.5  Tenant Remedies.  As more specifically provided elsewhere in this
           ---------------
Lease, upon Landlord's default, Tenant may pursue the remedies given in this
Lease.

     17.6  Mitigation.  Notwithstanding anything to the contrary herein, both
           ----------
Landlord and Tenant shall have the obligation to take reasonable steps to
mitigate their damages caused by any default under this Lease.

     17.7  Dispute Resolution Procedures.  Except with respect to actions by
           -----------------------------
Landlord to recover possession of the Premises through an unlawful detainer or
similar procedure, and except with respect to emergency matters for which a
restraining order or other similar equitable relief is necessary, the parties
agree to attempt to resolve any disputes under this Lease and related agreements
as follows: both parties covenant to provide a person authorized and empowered
to resolve any dispute that may arise to meet face to face with the person from
the other party upon ten (10) days prior notice at a mutually convenient place.
Such persons shall negotiate in good faith to attempt to resolve the dispute for
as long as either party so desires and in good faith believes progress can be
made. Failing a resolution of the dispute by this method, the parties shall
submit to non-binding mediation of the dispute with a mediator of their choice
with experience in mediating commercial disputes. Both parties shall pay an
equal share of the fees of the mediator prior to the commencement of the
mediation. Otherwise the parties shall each pay their own costs and expenses of
such mediation.  Failing resolution of the dispute by this method, the parties
shall resort to arbitration or litigation as provided herein. Any dispute under
this Lease shall not be subject to arbitration unless and to the extent required
by law or as otherwise agreed to by the parties or specifically stated herein.
When any dispute is to be arbitrated, the parties shall choose one arbitrator.
If the parties do not agree on an arbitrator within fifteen (15) days after
being requested to do so in writing, then either party may petition the Superior
Court of Washington to appoint an arbitrator. Each of the parties shall pay one-
half of the arbitrators' fees.  The arbitration shall be conducted in accordance
with Rules 2.3 through 8.1 of the Superior Court Mandatory Arbitration Rules
(MAR), 1997 official edition of the Washington Rules of Court, as they may be
amended from time to time. All disputes not required to be arbitrated after the
procedures of this Section have been undertaken shall be resolved by litigation
in an appropriate court of law.

18.  INTENTIONALLY DELETED

19.  SUBORDINATION, QUIET ENJOYMENT

     19.1  Subordination.  This Lease is subject to and is hereby subordinated
to all present and future mortgages, deeds of trust and other encumbrances
affecting the Premises, Building and Real Property subject to Tenant's right to
peaceful and quiet enjoyment and exclusive possession during the Lease term and
any extensions thereof, so long as Tenant is not in default hereunder. The
foregoing sentence is conditioned upon Landlord obtaining and delivering to
Tenant a nondisturbance agreement in which any person currently or hereafter
holding a mortgage, deed of trust or other encumbrance to which this Lease is to
be subordinate agrees to recognize this Lease upon foreclosure, trustee's sale
or deed in lieu thereof so long as the

                                      37
<PAGE>

Tenant is not in default under this Lease beyond the expiration of any
applicable cure period. Tenant will, upon demand by Landlord, execute such
instruments as may be reasonably required at any time, and from time to time, to
subordinate the rights and interests of the Tenant under this Lease to the lien
of any mortgage or trust deed at any time placed on the land or which the
Premises are a part; provided however, that such subordination shall not affect
Tenant's right to possession, use and occupancy of the Premises as long as
Tenant shall not be in default under any of the terms and conditions of this
Lease.

     19.2 Attornment and Estoppel.  Tenant further agrees:
          ------------------------

          (a)  That any such subordination agreement will contain a provision
satisfactory to Landlord's financing lender whereby Tenant will agree, in the
event of foreclosure of any such mortgage or trust deed to attorn to and
recognize as its Landlord under the terms of this Lease said lender or any
purchaser of the leased property at a foreclosure sale or their heirs,
successors, or assigns; and

          (b)  That it will execute and deliver to such lender a true Estoppel
Certificate in a form reasonably satisfactory to such lender.

20.  ESTOPPEL CERTIFICATES

Tenant shall, from time to time, upon written request of Landlord, execute,
acknowledge and deliver to Landlord or its designee a written statement stating:
the date this Lease was executed; the Commencement Date and Expiration Date; the
amount of minimum monthly Rent and the date to which such Rent has been paid;
and certifying to the extent true:  that this Lease is in full force and effect
and has not been assigned, modified, supplemented or amended in any way (or
specifying the date of the agreement so affecting this Lease); that this Lease
together with all Exhibits represents the entire agreement between the parties
as to this leasing; that all conditions under this Lease to be performed by
Landlord have been satisfied; that all required contributions by Landlord to
Tenant on account of Tenant's improvements have been received; that on this date
there are no existing defenses or offsets which the Tenant has against the
enforcement of this Lease by Landlord, and that not more than one month's Rent
has been paid in advance.  It is intended that any such statement delivered
pursuant to this Section may be relied upon by a prospective purchaser of
Landlord's interest or a mortgagee of Landlord's interest or assignee of any
mortgage upon Landlord's interest in the Building.  If Tenant shall fail to
respond within ten (10) days of receipt by Tenant of Landlord's written request,
Landlord shall give Tenant a second identical notice advising Tenant it has to
respond within five (5) business days after receipt by Tenant of said second
request by Landlord as herein provided, otherwise Tenant shall be deemed to have
given such certificate as above provided without modification and shall be
deemed to have admitted the accuracy of any information supplied by Landlord to
a prospective purchaser of mortgagee, that this Lease is in full force and
effect, that there are no uncured defaults in Landlord's performance, that the
security deposit is as stated in this Lease, and that not more than one month's
Rent has been paid in advance.  If, in Tenant's good faith opinion, there are
discrepancies between the terms stated on the Estoppel Certificates and the
agreement then in effect, including any known current defaults under this Lease
by either Landlord or Tenant, including written modifications to the Lease and
stating the date and nature of such modifications and including the date to
which the Basic Rent

                                      38
<PAGE>

and other sums payable under this Lease have been paid, that Tenant be allowed
to describe all such exceptions.

21.  ATTORNEY'S FEES

     21.1  Payment to Prevailing Party. If either party shall bring an action or
           ---------------------------
proceeding (including without limitation, any cross-complaint, counterclaim or
third party claim) against any other party by reason of the breach or alleged
violation of any covenant, term or obligation hereof, or for the enforcement of
any provision hereof, or to interpret, or otherwise arising out of this Lease,
except for the appraisal procedures of Section 2.2, the prevailing party in such
action or proceeding shall be entitled to its costs and expenses of suit,
including but not limited to reasonable attorneys' fees, which shall be payable
whether or not such action is prosecuted to judgment. "Prevailing party" within
the meaning of this Section shall include, without limitation, a party who
dismisses an action for recovery hereunder in exchange for full payment of the
sums allegedly due, performance of covenants allegedly breached or consideration
substantially equal to all of the relief sought in the action.

     21.2  Attorneys' Fees in Third Party Litigation.  If either party is
           -----------------------------------------
required to initiate or defend any action or proceeding with a third party
(including, without limitation, any cross-complaint, counterclaim or their party
claim) because of the other party's breach of this Lease, or otherwise arising
out of this Lease, and such party is the prevailing party in such action or
proceeding, then the party so initiating or defending shall be entitled to its
costs and expenses of suit, including but not limited to reasonable attorneys'
fees from the other party.

     21.3  Scope of Fees.  Attorneys' fees under this Section shall include
           -------------

shall construct the Building Shell and parking garage shell as defined in the
construction drawings and specifications listed in Exhibit "C-2" and as
generally described in Exhibit "C-3".  Tenant shall have the ability to

and colors as required by same.  Additions and/or modifications to the Building
which are requested by the Tenant shall be subject to Landlord's prior approval
pursuant to the provisions of the Construction Agreement.  Additions and/or
modifications to the Building which are requested by the Tenant shall be
incorporated at Tenant's expense if the changes involve any increase in the

in a delay of Substantial Completion, Landlord shall so notify Tenant prior to
the commencement of such work.  If Tenant elects to continue with such work, and
a delay in Substantial Completion results therefrom, Tenant shall be liable for
any additional costs and expenses incurred by Landlord.  If the modifications
requested by Tenant do not increase the cost or delay construction of the
Building and are otherwise approved by Landlord, then they shall be made without
cost to Tenant.

Substantial Completion or Final Completion.  The specific provisions regarding
the design and construction of the Link are set forth in more detail in Exhibit
"C".  Landlord agrees to provide Tenant with weekly updates on the status of the
governmental permits and approvals for the Link.  If Landlord is delayed in
obtaining the necessary governmental permits and approvals beyond December 31,
1998, Tenant shall have the right to work in a coordinated effort with Landlord
to obtain such permits and approvals or, at Tenant's election, take over the
permit and approval process provided, however, that if Tenant takes over the
permit and approval process Tenant shall provide Landlord with weekly updates on

freed and relieved from and after the date of such transfer, assignment or
conveyance of all liability as respects the performance of any covenants or

intent should arise.

  34.4  Waivers.  The waiver by Landlord or Tenant of any breach of any term,
        -------
covenant or condition herein contained shall not be deemed to be a waiver of any
subsequent breach of the same or any other term, covenant or condition herein
contained, nor shall any custom or practice which may grow up between the
parties in the administration of the terms hereof be deemed a waiver of or in
any way affect the right of either party to insist upon the performance by the
other party in strict accordance with said terms.  The subsequent acceptance or
payment of Rent shall not be deemed to be a waiver of any preceding breach by
either party of any term, covenant or condition of this Lease, other than the
failure of Tenant to pay the particular Rent so accepted, regardless of either
party's knowledge of such preceding breach at the time of acceptance of such
Rent.

  34.5    Quiet Enjoyment.  Provided Tenant observes its obligations under this
          ---------------
Lease, Tenant shall have peaceable and quiet enjoyment of the Premises

together with all access ways thereto, which are Common Areas as defined in
1.5(a)(i) above) may be designated by Landlord for the exclusive use of a new
building in the Newport Corporate Center located adjacent to the Building.  Such
parking shall be subject to such rules, regulations, and codes as may from time
to time be established by Landlord and/or governing authorities.  If a parking
administration program needs to be implemented at the Building, Tenant and
Landlord agree to cooperate in the program implementation and Tenant
acknowledges that Landlord's reasonable costs associated with the program will
be borne by all tenants in the Building on a pro rata basis, using the Tenant's
Percentage for each of the tenants affected.  In the event Tenant requests
reserved parking, Tenant shall pay rent for reserved parking at the rate of
$25.00 per stall, which rate may be adjusted by Landlord at the expiration of
the initial Term to market rate.  The thirty-three (33) parking stalls

Revenue Share:
Until such time as Mercata is able to track transaction revenue based on the
origin of each customer visit, the revenue shares under this agreement shall be
based on the percentage of Mercata's overall monthly net sales likely to have
resulted from Go2Net links. This percentage will be calculated by Mercata based
on the percentage of overall user sessions received through links from the
Go2Net site. Such percentage will be applied to Mercata's overall net sales on a
monthly basis to get the net sales presumably attributable to Go2Net. Go2Net's
revenue share will be [...***...] of such presumed net sale. The parties agree
not to artificially inflate the number of reported click throughs by their own
visits to the linked web page or other inappropriate means.
- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------
Impression Delivery Guarantee:
Go2Net agrees to guarantee Mercata [...***...] impressions over the course of
this advertising agreement. Should Go2Net fail to deliver all [...***...]
impressions prior to the expiration of this advertising agreement, Go2Net will
deliver the remainder of the impressions owed within 90 days of the contract
expiration at no extra charge.
- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------
Reporting Confidentiality/Audit Rights:
Go2Net will provide Mercata with a User ID and Password to access the Go2Net
reports database, providing detailed monthly reports accurately stating the
click through traffic from each Go2Net link to the Mercata site on a daily
basis, as well as all impressions delivered. Within 15 days of end of each
calendar month, Mercata will provide Go2Net with monthly reports accurately
stating overall user sessions per month and overall sales, and will present
Go2Net with calculations specifying the portion of net sales presumably
attributable to Go2Net (per the formula above), upon which the [...***...]
revenue share will be applied. Mercata's overall traffic, sales data and
customer information is highly confidential and proprietary to Mercata. As such,
Go2Net agrees to hold all such information in strict confidence and only use it
for the purposes of reviewing the revenue share calculations provided by
Mercata. Either party shall have the right, at its own expense and upon
reasonable notice, to audit reports supplied by the other party and the party
supplying the reports in question shall cooperate in good faith to facilitate
any audit that is requested.

Mercata may utilize a third-party partner to track and report transaction
revenue and make payments to Go2Net. In this matter, Go2Net agrees to work in
good faith with Mercata to negotiate an amendment to this agreement so that it
will be consistent with this third-party's tracking and payment practices.
- --------------------------------------------------------------------------------
Cancellation:

Either party will require 6 months of this contract to be completed before the
other party may cancel.  After 5 months has been completed, the canceling party
would be required to provide the other party with 30 day written notice of

in protecting the confidentiality of the other party's Confidential Information.
Notwithstanding the forgoing, either party may disclose the terms of this
Addendum when required to do so (i) by law or pursuant to any governmental rule,
