                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
     (ALL INFORMATION WITH RESPECT TO MARCH 31, 2000 AND 1999 IS UNAUDITED)

1.  Summary of Significant Accounting Policies

Basis of Presentation

   The financial statements are unaudited, other than the balance sheet at
December 31, 1999, and, in the opinion of management, reflect all adjustments
that are necessary for a fair presentation of the results for the periods shown.
The results of operations for such periods are not necessarily indicative of the
results expected for the full fiscal year or for any future period. These
financial statements should be read in conjunction with the financial statements
as of December 31, 1999 and related notes included in the Company's Annual
Report on Form 10-K/A filed with the Securities and Exchange Commission (the
"SEC") on April 28, 2000.  The Company formerly reported as a development stage
company.

Principles of Consolidation

   The consolidated financial statements include the accounts of Stamps.com Inc.
and its majority-owned subsidiaries.  All significant intercompany accounts and
transactions have been eliminated.

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 amounts reported in the financial statements and the accompanying
notes.  Actual results could differ from those estimates and such differences
may be material to the financial statements.

Cash and Short-term Investments

   The Company considers all highly liquid investments with an original or
remaining maturity of three months or less at the date of purchase to be cash
equivalents.

   The Company's short-term investments are comprised of U.S. government
obligations and public corporate debt securities with maturities of less than
one year at the date of purchase.  All short-term investments are classified as
available for sale and are recorded at market using the specific identification
method.  Realized gains and losses are reflected in other income and expense
while unrealized gains and losses, which to date have not been material, are
included as a separate component of stockholders' equity.

Reclassifications

   Certain prior period balances have been reclassified to conform to current
period presentation.

2.   Acquisition of iShip.com

     On March 7, 2000, Stamps.com (the Company) completed the acquisition of
iShip.com, Inc. (iShip), a development stage enterprise developing Internet-
based shipping technology. In connection with the acquisition, approximately 5.6
million shares of Stamps.com common stock were issued in exchange for all
outstanding iShip stock. An additional 1.6 million shares of Stamps.com common
stock have been reserved for issuance upon exercise of options and warrants
assumed in the transaction. Finally, 800,000 shares of Stamps.com common stock
have been deposited into an escrow account. The escrow amount is intended to
compensate the Company for any inaccuracy or breach of any representation,
warranty, covenant or agreement of iShip as contained in the merger agreement.
The shares must remain in the escrow fund for a period of one year from the
close of the acquisition. The parties are currently not aware of any inaccuracy
or breach of any representation, warranty, covenant or agreement of iShip as
contained in the merger agreement.

     The acquisition was accounted for as a purchase in accordance with the
provisions of Accounting Principles Board Opinion ("APB") No. 16.  Under the
purchase method of accounting, the purchase price was allocated to the assets
acquired and liabilities assumed based on their estimated fair values at the
date of acquisition.  The Company recorded intangible assets of $220.3 million
and deferred compensation of $24.7 million, which will be amortized over periods
ranging from three to four years.  Results of operations for iShip have been
included with those of the Company for periods subsequent to the acquisition
date.

     The purchase price was allocated as follows (in thousands):

   Goodwill                                                  $209,188

3.   Change in Subsidiary Ownership

     On February 17, 2000, the Company announced that it sold approximately
38% of EncrypTix, Inc., until then a wholly owned subsidiary, in a private
financing of approximately $30 million.  The financing was completed in March
2000.

     In April 2000, EncrypTix received an additional $6 million in private
financing.  Upon completion of the financing, the Company will maintain an
ownership percentage of approximately 58%.

     The Company includes EncrypTix's balances and results in its consolidated
financial statements.  The minority interest reflected in the attached
consolidated balance sheet represents the investment received in the private
financing.

4.   Segment Information

     In connection with the acquisition of iShip, the Company announced the
organization of three specialized strategic business units (SBUs) focused on the
enterprise, e-commerce and small business market segments of the core mailing
and shipping services.  The Enterprise SBU will offer companies with more than
1,000 employees an Internet-based, multi-carrier mailing and shipping service.
The E-commerce SBU addresses the shipping needs of e-tailers and other online
businesses, including auctioneers.  The Small

                                       6
<PAGE>

Business SBU provides small businesses and consumers with Internet Postage and
shipping services. The Company will begin reporting under the SBUs in the second
quarter of 2000.

5.  Legal Proceedings

    Please refer to "Part II--Other Information--Item 1" of this report for a
discussion of legal proceedings.


6.   Computation Of Historical Net Loss Per Share

     Basic earnings per share is computed by dividing the net earnings available
to common stockholders for the period by the weighted average number of common
shares outstanding during the period. Diluted earnings per share is computed by
dividing the net earnings for the period by the weighted average number of
common and common equivalent shares outstanding during the period.

     Common equivalent shares, consisting of unvested restricted common stock
and incremental common shares issuable upon the exercise of stock options and
warrants and upon conversion of convertible preferred stock, are excluded from
the diluted earnings per share calculation if their effect is anti-dilutive.

7.   Subsequent Event

     In February 2000, Mr. Payne (Chairman of the Board and Chief Executive
Officer) purchased 187,000 shares of the Company's common stock on the open
market for an aggregate purchase price of approximately $6.0 million.  The
shares were purchased on margin by Mr. Payne and the margin account was secured
by a pledge of 1,467,500 shares of the Company's common stock held by Mr. Payne.
In April 2000, the Company agreed to guarantee Mr. Payne's margin account in the
event the value of the shares pledged becomes insufficient collateral to secure
the indebtedness outstanding under the margin account.  The guarantee is in the
form of a single-purpose line of credit extended to Mr. Payne which will have a
balance due to the extent the value of the pledged shares is insufficient
collateral to secure indebtedness outstanding under the margin account.  This
line of credit is secured by all of Mr. Payne's assets.

Overview

     Stamps.com Inc. provides the easiest and smartest way to mail or ship
letters, packages or small parcels anywhere or anytime by offering a convenient,
cost effective and easy-to-use service for purchasing and printing postage over
the Internet.  On October 22, 1999, we commercially launched our Internet
Postage Service and on March 7, 2000 we completed our acquisition of iShip.com,
a development stage enterprise developing Internet-based shipping technology.
As a result of the acquisition, our expanded offerings create an efficient
marketplace where any size business can choose the best carrier, price and
delivery terms for every mailing or shipping transaction based on sophisticated,
real time rating, tracking and pricing tools.  To date, our operating activities
have consisted primarily of our efforts to promote our brand, build market
awareness, attract new customers, recruit personnel, build operating
infrastructure and develop our Web site and associated systems that we use to
process customers' orders and payments.  As of March 31, 2000, our customer base
consisted of over 187,000 users who had downloaded our software and registered
for our service.

     Small Business Services: Our small business services include our
traditional business of serving small businesses and consumers with the easiest
Internet Postage service as well as offering multi-carrier document and package
shipping to companies with less than 100 employees.

     The revenues from our small business services consist primarily of the
revenues from our Internet Postage Service and commission fees from our on-line
store operated by a third-party. Service fee revenues are generated from our
basic service plan that we are currently offering to our users. Under this plan,
a user purchases postage at cost and is charged a monthly convenience fee of 10%
of the value of postage printed during a month. There is a monthly minimum fee
of $1.99 and a monthly maximum fee of $19.99. Service fees are calculated and
charged at the end of a monthly billing cycle. Although we have established a
basic pricing plan, we may need to change our pricing or add variations to the
basic service plan given the lack of an established or proven commercial market
for Internet Postage.

     The revenues from our Internet-based shipping services are primarily
generated from recurring, transaction-based service fees.  Also, we generate
revenues from advertising and revenue share arrangements.  We expect revenues to
increase significantly in 2000 as we continue to grow our customer base in the
Internet Postage service and as we fully rollout our Internet-based shipping
services.

     Enterprise Services: We offer companies with more than 1,000 employees an
Internet-based, multi-carrier mailing and shipping service. The enterprise
service will allow corporations to centrally manage and control costs from
mailing and shipping activities across multiple carriers and can be distributed
to thousands of corporate desktops using only a Web browser. The largest
customer to date of the enterprise service is Mail Boxes Etc., a retail
business, communication and postal services franchiser.

                                       8
<PAGE>

Revenues from our enterprise service will be generated from recurring,
transaction-based service fees as well as fixed monthly service fees.

     E-commerce Services:  Our E-commerce services strategic business unit
addresses the growing shipping needs of e-tailers and other online-businesses,
including auctioneers.  Through our current partnerships with premier auction
Web sites such as eBay and AuctionRover.com, we will provide mailing and
shipping services available at the conclusion of any transaction on the
Internet.  These services will be embedded in auction Web sites, e-tailer
"shopping carts" and other points-of-purchase on various Web sites, enabling
buyers and sellers to select precise pricing and delivery terms from among a
variety of carrier choices.  Revenues from our E-commerce services will be
primarily generated from recurring, transaction-based service fees.

     From time to time, we may offer special promotions to attract new
customers to our mailing and shipping services. Currently, these promotions
involve waiving or discounting convenience fees, discounts on supplies offered
through Stamps.com's online store, or free postage. We cannot predict the impact
of any promotion or pricing plan changes and our ability to generate revenues or
achieve profitability could be adversely affected by special promotions or
changes to pricing plans. Furthermore, given the lack of an established or
proven commercial market for our services, we are unable to quantify the total
impact of these promotions on revenue and profitability. In addition, with the
current limited commercial roll-out of our Internet shipping services and the
early stage of the commercial market for Internet-shipping services, we cannot
be sure of our ultimate pricing approach for such services or that fees from
Internet shipping services will generate significant revenues, if at all. See
"Risk Factors--We have a history of losses and expect to incur losses in the
future and may never achieve profitability."

Results of Operations

     Revenues. Revenues are generated from fees from our Internet-based mailing
and shipping services, commission fees and advertising. Revenues were
approximately $2.0 million for the three months ended March 31, 2000. There were
no revenues during the three months ended March 31, 1999 as we launched our
first service, Internet Postage, on October 22, 1999. During the three months
ended March 31, 2000, more than 114,000 new customers were added for a net
ending customer balance of 187,000 at March 31, 2000. We expect revenues to
increase as we continue to add new customers and expand our service offerings in
the enterprise and e-commerce strategic business units later this year.

     Cost of Revenues.  Cost of revenues primarily consist of costs related to
customer service activities and server and network operations and, to a lesser
extent, bank processing charges for customer fees paid by credit card, Internet
connection charges, depreciation of server and network equipment and allocation
of overhead.  Costs of revenues were $3.7 million for the three months ended
March 31, 2000.  As of March 31, 1999, there were no costs of revenues because
we had not recognized any revenues to date.  We expect cost of revenues to
increase as we continue to add new customers and expand the enterprise and e-
commerce strategic business units.

     Sales and Marketing Expenses. Sales and marketing expenses include costs to
acquire and retain customers, including costs associated with strategic
relationships, advertising and promotions and compensation and related expenses
for personnel engaged in marketing and business development activities. Sales
and marketing expenses were $22.5 million for the three months ended March 31,
2000. We incurred no sales and marketing expenses during the three months ended
March 31, 1999. The increase in sales and marketing is principally due to our
marketing campaign and advertising of our Internet-based mailing and shipping
services. We expect sales and marketing expenses to increase significantly as we
continue to promote our brand through new strategic relationships and marketing
campaigns.

     Research and Development Expenses. Research and development expenses
principally consist of compensation for personnel involved in the development of
our Internet Postage service and expenditures for consulting services and third-
party software. Research and development expenses for the three months ended
March 31, 2000 were approximately $3.4 million compared to $1.2 million for the
three months ended March 31, 1999. The increase is due to higher personnel and
consulting costs associated with the ongoing development of our Internet-based
mailing and shipping services. We believe that significant investments in
research and development are required to remain competitive and expect to
continue incurring significant research and development expenses.

     General and Administrative Expenses.   General and administrative expenses
primarily consist of compensation and related costs for executive and
administrative personnel, facility costs, and fees for legal and other
professional services.  General and administrative expenses for the three months
ended March 31, 2000 were $5.8 million compared to $2.1 million for the three
months ended March 31, 1999.  The increase is principally due to increased
headcount and the expansion of our facilities related to the growth of our
business, as well as legal fees related to the Pitney Bowes patent infringement
claim. We expect general and administrative expenses to increase as we grow our
business and incur additional costs related to the Pitney Bowes infringement
claim.

     Amortization of Goodwill and Other Intangibles.  Amortization of goodwill
and other intangibles is principally due to the goodwill resulting from the
acquisition of iShip.com in March 2000. Amortization expense is expected to
increase significantly as the goodwill and other intangibles resulting from our
acquisition are amortized over useful lives ranging from three to four years.

     Acquired in-Process Research and Development

     The Company incurred a total of $2 million in acquired in-process research
and development charges in connection with its acquisition of iShip.com in March
2000. With regards to the in-process research and development projects, the
Company considered, among other factors, the stage of development of each
project at the time of acquisition and the projected incremental cash flow for
the projects when completed as well as any associated risks.

     Deferred Compensation Amortization

     During 1998 and 1999, we granted stock options with exercise prices that
were less than the estimated fair value of the underlying shares of common stock
for accounting purposes on the date of grant. This will result in amortization
expenses of deferred compensation over the period that these options vest, which
ranges from three to four years from the date of grant.

     Interest Income (Expense), Net.  Interest income (expense), net consists of
income from our cash and cash equivalents net of interest expense related to
financing our obligations. Interest income (expense), net for the three months
ended March 31, 2000 was $4.9 million compared to $2,000 for the three months
ended March 31, 1999. The increase is due to earnings on a higher average cash
equivalent balance as a result of our initial public offering in June 1999 and
our follow-on public offering in December 1999.

Liquidity and Capital Resources

     As of March 31, 2000, the Company had approximately $368.3 million in cash
and short-term investments.  In June 1999, we completed our initial public
offering in which the underwriters sold to the public 5,750,000 shares of common
stock at $11.00 per share.  The net proceeds from the offering were $10.23 per
share, or $58.8 million in the aggregate.  In December 1999, we completed a
follow-on public offering in which the underwriters sold to the public 5,750,000
shares of the common stock at $65.00 per share.  Our net proceeds from the
offering were $61.83 per share, or $355.5 million in the aggregate.  We
regularly invest excess funds in short-term money market funds and commercial
paper and do not engage in hedging or speculative activities.

     Through April 2000, our majority-owned subsidiary, EncrypTix, raised
approximately $36.0 million in private financing from a group of financial and
strategic investors. The proceeds of this financing will be used by EncrypTix
for research and development, sales and marketing and general working capital
purposes.

     In February 2000, we entered into a facility lease agreement for our
Bellevue, Washington location with aggregate minimum lease payments of
approximately $15.2 million through fiscal year ending December 31, 2008.

     Net cash used in operating activities was $26.5 million for the three
months ended March 31, 2000 compared to $2.9 million for the three months ended
March 31, 1999. The increase in net cash used in operating activities resulted
primarily from increases in net loss, principally due to sales and marketing
expenses as well as research and development and general expenditures.

     Net cash used in investing activities was $60.1 million for the three
months ended March 31, 2000 compared to $333,000 for the three months ended
March 31, 1999. The increase in net cash used in investing activities resulted
primarily from net purchases of short-term investments and increased capital
expenditures for computer equipment, purchased software and office equipment.

     Net cash provided by financing activities was $29.9 million for the three
months ended March 31, 2000 compared to $28.3 million for the three months ended
March 31, 1999.  The increase in net cash provided by financing activities
resulted principally from the private financing of EncrypTix, our majority-owned
subsidiary.

     We anticipate that our current cash balances will be sufficient to fund our
operations, including the acquired operations of iShip.com, through fiscal year
2001. However, we may require substantial working capital to fund our business
and may need to raise additional capital. We cannot be certain that additional
funds will be available on satisfactory terms when needed, if at all.

Quantitative and Qualitative Disclosure about Market Risk

     We are exposed to interest rate risk from the short-term investments and
line of credit. At March 31, 2000, the short-term investments, which consist
principally of corporate debt and commercial paper, approximated $330.7 million
and had a related weighted average interest rate of 6.3%. At March 31, 2000, the
line of credit balance totaled $1 million and the related interest rate was 9.5%
(the bank's prime rate plus 1%).

     If market interest rates continue to rise, the value of the short-term
investments will continue to decrease. We currently hold no derivative
instruments and do not earn foreign-source income. We expect to invest only in
short-term, investment grade and interest-bearing instruments.

                                 RISK FACTORS

     BEFORE DECIDING TO INVEST IN OUR COMPANY OR TO MAINTAIN OR INCREASE YOUR
INVESTMENT, YOU SHOULD CAREFULLY CONSIDER THE RISKS DESCRIBED BELOW, IN ADDITION
TO THE OTHER INFORMATION IN THIS REPORT AND OUR OTHER FILINGS WITH THE SEC.  THE
RISKS AND UNCERTAINTIES DESCRIBED BELOW ARE NOT THE ONLY ONES FACING OUR
COMPANY.  ADDITIONAL RISKS AND UNCERTAINTIES NOT PRESENTLY KNOWN TO US OR THAT
WE CURRENTLY DEEM IMMATERIAL MAY ALSO AFFECT OUR BUSINESS OPERATIONS. IF ANY OF
THE FOLLOWING RISKS ACTUALLY OCCUR, THAT COULD SERIOUSLY HARM OUR BUSINESS,
FINANCIAL CONDITION OR RESULTS OF OPERATIONS. IN SUCH CASE, THE MARKET PRICE FOR
OUR COMMON STOCK COULD DECLINE AND YOU MAY LOSE ALL OR PART OF YOUR INVESTMENT.

                 We face risks associated with our operations

If we do not effectively manage the commercial release of our Internet mailing
and shipping services, our business will be harmed.

     On August 9, 1999, our Internet Postage service was approved by the US
Postal Service for commercial release. On October 22, 1999, we began to offer
our Internet Postage service commercially. Our Internet shipping services have
not yet been introduced on a commercial scale. We face numerous risks coincident
with the introduction of our services. For example, our mailing and shipping
services have not yet been subjected to the demands of widespread commercial
use. We cannot be sure that our services will successfully process large numbers
of user transactions. If we experience problems with the scalability or
functionality of our services, our full commercial deployment could be delayed
and our results of operations would be adversely impacted.

     The continued commercial roll-out of our Internet Postage service is
dependent upon our service continuing to meet US Postal Service performance
specifications and regulations. For example, our service must continue to
perform according to US Postal Service specifications in order to receive
additional license certificates necessary to add customers. Meanwhile, our
Internet mailing and shipping services must meet the commercial demands of our
customers, which are primarily expected to range from small businesses to large
enterprises. We are currently conducting a national customer registration
campaign, particularly for our Internet Postage service; however, we have very
limited experience conducting marketing campaigns, and we may fail to generate
significant interest. Additionally, we have limited experience selling our
services to enterprise customers and cannot predict the length of enterprise
sales cycles or implementation times for our services. On the other hand, if we
experience extensive interest in our services, we may fail to meet the
expectations of customers due to limited experience in operating our services
and the strains this demand will place on our Web site, network infrastructure
and systems.

     Our ability to obtain and retain customers depends on the attractiveness of
our service to our customers and on our customer service capabilities. If we are
unable at any time to address customer service issues adequately or to provide a
satisfactory customer experience for current or potential customers, our
business and reputation may be harmed.

Success by Pitney Bowes in its suit against us alleging patent infringement
could prevent us from offering our Internet Postage service and severely harm
our business or cause it to fail.

     On June 16, 1999, Pitney Bowes filed a patent infringement lawsuit against
us. The suit alleges that we are infringing two patents held by Pitney Bowes
related to postage application systems and electronic indicia. The suit seeks
treble damages, a preliminary and permanent injunction from further alleged
infringement, attorneys' fees and other unspecified damages. We answered the
complaint on August 6, 1999, denying the allegations of patent infringement and
asserting a number of affirmative defenses. Pitney Bowes filed a similar
complaint in early June 1999 against one of our competitors, E-Stamp
Corporation, alleging infringement of seven Pitney Bowes patents. On April 13,
2000, Pitney Bowes asked the court for permission to amend its complaint to drop
allegations of patent infringement with respect to one patent and to add
allegations of patent infringement with respect to three other patents.

     The outcome of the litigation that Pitney Bowes has brought against us is
uncertain. Therefore, we can give no assurance that Pitney Bowes will not
prevail in its suit against us.

     If Pitney Bowes prevails in its suit against us, we may be prevented from
selling postage on the Internet. Alternatively, the Pitney Bowes suit could
result in limitations on how we implement our service, delays and costs
associated with redesigning our service and payments of license fees and other
payments. Thus, if Pitney Bowes prevails in its suit against us, our business
could be severely harmed or fail.

                                       11
<PAGE>

     In addition, the litigation could result in significant expenses and
diversion of management time and other resources.

     On August 17, 1998, Pitney Bowes issued a press release stating that it
holds dozens of US patents related to computer-based postage metering and that
it intended to engage in discussions with other marketers of computer-based
postal products to license Pitney Bowes technology. Prior to Pitney Bowes filing
a lawsuit against us, we were in license discussions with Pitney Bowes. We
intend to continue these discussions; however, we cannot predict whether these
discussions will continue, the outcome of these discussions or the impact of
Pitney Bowes' intellectual property claims on our business or the Internet
postage market. If Pitney Bowes is able to prevail in its claims against us and
if we do not enter into a license relationship with Pitney Bowes, our business
could be impacted severely or fail. In addition, as described above, Pitney
Bowes could obtain monetary and injunctive relief against us.

The Internet postage and shipping markets are new and uncertain and our business
may not develop.

     The markets for Internet postage and shipping have not developed, and their
development is subject to substantial uncertainty. We cannot assure you that
these markets will develop.

     We depend heavily on the commercial acceptance of our Internet Postage
service. We cannot predict if our target customers will choose the Internet as a
means of purchasing postage, or if customers will be willing to pay a fee to use
our service, or if potential users will select our system over our competitors.
Our target customers often have alternatives to the US Postal Service and
shipping services, including online invoicing, bill payment and financial
transactions. The General Accounting Office, in a report issued on October 21,
1999, stated that competition from these alternatives could lead to substantial
declines in the US Postal Service's First Class Mail volume in the next decade.
These trends could limit the market opportunity for our Internet Postage
service. In addition, the US Postal Service could suspend, terminate or offer
services which compete against Internet postage, any of which could stop or
negatively impact the commercial adoption of our Internet Postage service.

     In addition, our acquisition of iShip.com in March 2000 represents our
entry into the market for online shipping services. There can be no assurance
that we will succeed in this business. The market for online shipping services
is new and uncertain and may not develop. In addition, we have not released our
shipping services on a commercial scale and we currently have no customers and
no revenues attributable to our online shipping services. Our ability to obtain
and retain customers will depend on the attractiveness of our service to our
customers and on our customer service capabilities. If we experience significant
system, customer service, security or other problems once we begin commercial
operation of our shipping services, customers may stop using or refuse to try
these and other services we offer. In addition, shippers may terminate or limit
their relationships with us. The occurrence of these problems could have a
material adverse effect on our business, financial condition or results of
operations.

The integration of our company and iShip.com will present significant
challenges. We may not be able to realize the benefits we anticipate from the
acquisition of iShip.com.

     As a result of our acquisition of iShip.com in March 2000, we face
significant challenges in integrating organizations, operations, technology,
product lines and services in a timely and efficient manner and in retaining key
personnel and strategic partnerships of both companies. Cost synergies, revenue
growth, technological development and other synergistic benefits may not
materialize. Diversion of management attention, loss of management-level and
other highly qualified employees, and an inability to integrate management,
systems and operations of these two companies may all result from the
acquisition. The failure to integrate our company and iShip.com successfully and
to manage the challenges presented by the integration process may result in our
company and iShip.com not achieving the anticipated potential benefits of the
acquisition. Delays encountered in the transition process could have a material
adverse effect upon the combined company.

     Further, the physical expansion in facilities that have occurred as a
result of this acquisition may result in disruptions that seriously impair our
business. In particular, we now have operations in multiple facilities in
geographically distant areas. We are not experienced in managing facilities or
operations in geographically distant areas.

We have a history of losses and expect to incur losses in the future, and we may
never achieve profitability.

     As of March 31, 2000, we had not generated any significant revenues and had
an accumulated deficit of $97.6 million. Our accumulated deficit includes
iShip.com's losses from the date of acquisition, March 7, 2000. Our lack of
revenues can be attributed primarily to the fact that our Internet Postage
service had not been released commercially until October 22, 1999 and that the
Internet shipping services developed by iShip.com had yet to be released on a
commercial scale. Due to the need to establish our brand and service, we expect
to incur increasing sales

                                      12
<PAGE>

and marketing, research and development, and administrative expenses and
therefore could continue to incur net losses for at least the next several years
or longer. As a result of the iShip.com acquisition, we expect that our losses
will increase even more significantly because of additional costs and expenses
related to an increase in the number of employees; an increase in sales and
marketing activities; additional facilities and infrastructure; and assimilation
of operations and personnel. Overall, we will need to generate significant
revenues to achieve and maintain profitability.

     In connection with the iShip.com acquisition, we will record a significant
amount of intangibles, the amortization of which will significantly and
adversely affect our operating results. To the extent we do not generate
sufficient cash flow to recover the amount of the investment recorded, the
investment may be considered impaired and could be subject to an immediate
write-down of up to the full amount of the investment. In this event, our net
loss in any given period could be greater than anticipated and the market price
of our stock could decline. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

     Our ability to generate gross margins generally assumes that if a market
for our services develops, we must generate significant revenues from a large
base of active customers. We currently charge our customers a fee to use our
Internet Postage service. We have yet to determine how customers will be charged
for our Internet shipping services. In order to attract customers, we may run
special promotions and offer discounts on fees, postage and supplies. However,
given the lack of an established or proven commercial market for our services,
we cannot be sure that customers will be receptive to our fee structures. Even
if we are able to establish a sizeable base of users, we still may not generate
sufficient gross margins to become profitable. In addition, our ability to
generate revenues or achieve profitability could be adversely affected by
special promotions or changes to our pricing plans. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations."

If we cannot effectively manage our growth, our ability to provide services will
suffer.

     Our reputation and ability to attract, serve and retain our customers
depend upon the reliable performance of our Web site, network infrastructure and
systems. We have a limited basis upon which to evaluate the capability of our
systems to handle controlled or full commercial availability of our Internet
Postage service or our online shipping services. We have recently expanded our
operations significantly, and further expansion will be required to address the
anticipated growth in our user base and market opportunities. To manage the
expected growth of operations and personnel, we will need to improve existing
and implement new systems, procedures and controls. In addition, we will need to
expand, train and manage an increasing employee base. We will also need to
expand our finance, administrative and operations staff. As a result of the
iShip.com acquisition, we will need to assimilate substantially all of
iShip.com's operations into our operations.

     We may not be able to manage our growth effectively. Our current expansion
has and will continue to place a significant strain on our managerial,
operational and financial resources. Our current and planned personnel, systems,
procedures and controls may be inadequate to support our future operations. If
we are unable to manage our growth effectively or experience disruptions during
our expansion, our business will suffer and our financial condition and results
of operations will be seriously affected.

If we are unable to maintain and develop our strategic relationships and
distribution arrangements, our Internet mailing and shipping services may not
achieve commercial acceptance.

     We have established strategic relationships with a number of third parties.
Our strategic relationships generally involve the promotion and distribution of
our services through our partners' products, services and Web sites.
Additionally, some of our relationships provide for the inclusion of our logo or
promotional offers for our service in packaging and marketing materials utilized
by our partners. In return for promoting our service, our partners may receive
revenue-sharing opportunities. In order to achieve wide distribution of our
services, we believe we must establish additional strategic relationships to
market our services effectively. If one or more of our partners terminates or
limits its relationship with us, our business could be severely harmed or fail.
We have limited experience in establishing and maintaining strategic
relationships and we may fail in our efforts to establish and maintain these
relationships.

     Our current strategic relationships, including those established by
iShip.com, have not yet resulted in significant revenues, primarily because we
have only recently commercially released our Internet Postage service and our
online shipping services have yet to be released on a commercial scale. As a
result, our strategic partners may not view their relationships with us as
significant or vital to their businesses and consequently, may not perform
according to our expectations. We have little ability to control the efforts of
our strategic partners and, even if we are successful in establishing strategic
relationships, these relationships may not be successful.

                                       13

We face risks typical of early stage companies and of new and rapidly changing
markets.

     You should consider our prospects in light of the risks and difficulties
frequently encountered by early stage companies and those in new and rapidly
evolving markets. These risks include, among other things, our (a) ability to
meet and maintain government specifications for our Internet Postage service,
specifically US Postal Service requirements; (b) complete dependence on Internet
mailing and shipping services that currently do not have broad market
acceptance; (c) need to expand our sales and support organizations; (d) ability
to establish and promote our brand name; (e) ability to expand our operations to
meet the commercial demand for our services; (f) development of and reliance on
strategic and distribution relationships; (g) ability to prevent and respond
quickly to service interruptions; (h) ability to minimize fraud and other
security risks; and (i) ability to compete with companies with greater capital
resources and brand awareness.

If we do not achieve the brand recognition necessary to succeed in the Internet
mailing and shipping markets, our business will suffer.

     We must quickly build our Stamps.com brand to gain market acceptance for
our services. We believe it is imperative to our long term success that we
obtain significant market share for our services before other competitors enter
the Internet postage and shipping markets. We must make substantial expenditures
on product development, strategic relationships and marketing initiatives in an
effort to establish our brand awareness. In addition, we must devote significant
resources to ensure that our users are provided with a high quality online
experience supported by a high level of customer service. We cannot be certain
that we will have sufficient resources to build our brand and realize commercial
acceptance of our services. If we fail to gain market acceptance for our
services, our business will suffer dramatically or may fail.

System and online security failures could harm our business and operating
results.

     Our services depend on the efficient and uninterrupted operation of our
computer and communications hardware systems. In addition, we must provide a
high level of security for the transactions we execute. We rely on internally-
developed and third-party technology to provide secure transmission of postage
and other confidential information. Any breach of these security measures would
severely impact our business and reputation and would likely result in the loss
of customers. Furthermore, if we are unable to provide adequate security, the US
Postal Service could prohibit us from selling postage over the Internet.

     Our systems and operations are vulnerable to damage or interruption from a
number of sources, including fire, flood, power loss, telecommunications
failure, break-ins, earthquakes and similar events. We have entered into an
Internet hosting agreement with Exodus Communications, Inc. to maintain our
Internet postage servers at Exodus' data center in Southern California. Our
operations depend on Exodus' ability to protect its and our systems in its data
center against damage or interruption. Exodus does not guarantee that our
Internet access will be uninterrupted, error-free or secure. Our servers are
also vulnerable to computer viruses, physical, electrical or electronic break-
ins and similar disruptions. We have experienced minor system interruptions in
the past and may experience them again in the future. Any substantial
interruptions in the future could result in the loss of data and could
completely impair our ability to generate revenues from our service. We do have
a business interruption plan that we continue to refine and update; however, we
do not presently have a full disaster recovery plan in effect to cover loss of
facilities and equipment. In addition, we do not have a "fail-over" site that
mirrors our infrastructure to allow us to operate from a second location. We
have business interruption insurance; however, we cannot be certain that our
coverage will be sufficient to compensate us for losses that may occur as a
result of business interruptions.

     A significant barrier to electronic commerce and communications is the
secure transmission of confidential information over public networks. Anyone who
is able to circumvent our security measures could misappropriate confidential
information or cause interruptions in our operations. We may be required to
expend significant capital and other resources to protect against potential
security breaches or to alleviate problems caused by any breach. We rely on
specialized technology, both within our own infrastructure and that provided by
Exodus, to provide the security necessary for secure transmission of postage and
other confidential information. Advances in computer capabilities, new
discoveries in security technology, or other events or developments may result
in a compromise or breach of the algorithms we use to protect customer
transaction data. Should someone circumvent our security measures, our
reputation, business, financial condition and results of operations could be
seriously harmed. Security breaches could also expose us to a risk of loss or
litigation and possible liability for failing to secure confidential customer
information. As a result, we may be required to expend a significant amount of
financial and other resources to protect against security breaches or to
alleviate any problems that they may cause.

If we do not expand our product and service offerings, our business may not
grow.

     We may establish subsidiaries, enter into joint ventures or pursue the
acquisition of new or complementary businesses, products or technologies in an
effort to enter into new business areas, diversify our sources of revenue and
expand our product and service offerings outside the Internet postage market. We
have no commitments or agreements and are not currently engaged in discussions
for any material acquisitions or investments. We continue to evaluate
incremental revenue opportunities and derivative applications of our technology
and may pursue and develop those opportunities with strategic partners and
investors. To the extent we pursue new or complementary businesses, we may not
be able to expand our service offerings and related operations in a cost-
effective or timely manner. We may experience increased costs, delays and
diversions of management's attention when integrating any new businesses or
service. We may lose key personnel from our operations or those of any acquired
business. Furthermore, any new business or service we launch that is not
favorably received by users could damage our reputation and brand name in the
Internet postage and shipping or other markets that we enter. We also cannot be
certain that we will generate satisfactory revenues from any expanded services
or products to offset related costs. Any expansion of our operations would also
require significant additional expenses, and these efforts may strain our
management, financial and operational resources. Additionally, future
acquisitions may also result in potentially dilutive issuances of equity
securities, the incurrence of additional debt, the assumption of known and
unknown liabilities, and the amortization of expenses related to goodwill and
other intangible assets, all of which could have a material adverse effect on
our business, financial condition and operating results. New issuances of
securities may also have rights, preferences and privileges senior to those of
our common stock.

Fluctuations in our operating results could cause our stock price to fall.

     Prior to our commercial launch on October 22, 1999, we had not generated
any revenues from our operations. Accordingly, we have a limited basis upon
which to predict future operating results. We expect that our revenues, margins
and operating results will fluctuate significantly due to a variety of factors,
many of which are outside of our control. These factors include: (a) the success
of the commercial release of our Internet Postage and online shipping services;
(b) the costs of defending ourselves in the Pitney Bowes litigation or against
other intellectual property claims; (c) the costs of our marketing programs to
establish and promote the Stamps.com brand name; (d) the demand for our Internet
Postage and shipping services; (e) our ability to develop and maintain strategic
distribution relationships; (f) the number, timing and significance of new
products or services introduced by both us and our competitors; (g) our ability
to develop, market and introduce new and enhanced services on a timely basis;
(h) the level of service and price competition; (i) the increases in our
operating expenses as we expand operations; (j) US Postal Service regulation and
policies and (k) general economic factors.

     Our cost of revenues includes costs for systems operations, customer
service, Internet connection and security services; all of these costs will
fluctuate depending upon the demand for our services. In addition, a substantial
portion of our operating expenses is related to personnel costs, marketing
programs and overhead, which cannot be adjusted quickly and are therefore
relatively fixed in the short term. Our operating expense levels are based, in
significant part, on our expectations of future revenues. If our expenses
precede increased revenues, both gross margins and results of operations would
be materially and adversely affected.

     Due to the foregoing factors and the other risks discussed in this report,
you should not rely on period-to-period comparisons of our results of operations
as an indication of future performance. It is possible that in some future
periods our results of operations will be below the expectations of public
market analysts and investors. In this event, the market price of our common
stock is likely to decline.

We rely on a relatively new management team and need additional personnel to
grow our business.

     Our management team is relatively new. We hired our Chairman and Chief
Executive Officer in October 1998, our President and Chief Operating Officer in
October 1999 and our Chief Financial Officer in September 1998. We have also
recently hired or intend to hire senior managers for our strategic business
units. There can be no assurance that we will successfully assimilate our
recently hired managers or that we can successfully locate, hire, assimilate and
retain qualified key management personnel. Our business is largely dependent on
the personal efforts and abilities of our senior management, including our
Chairman and Chief Executive Officer, our President and Chief Operating Officer,
and our Chief Financial Officer. Any of our officers or employees can terminate
his or her employment relationship at any time. The loss of these key employees
or our inability to attract or retain other qualified employees could have a
material adverse effect on our results of operations and financial condition.

     Our future success depends on our ability to attract, retain and motivate
highly skilled technical, managerial, marketing and customer service personnel.
Also, our success will also depend on a successful integration of iShip.com's
management with our senior management team. We plan to hire additional personnel
in all areas of our business. Competition for qualified personnel is intense,

                                       15
<PAGE>

particularly in the Internet and high technology industries. As a result, we may
be unable to successfully attract, assimilate or retain qualified personnel.
Further, we may be unable to retain the employees we currently employ or attract
additional technical personnel. The failure to retain and attract the necessary
personnel could seriously harm our business, financial condition and results of
operations.

Third party assertions of violations of their intellectual property rights could
adversely affect our business.

     In addition to the Pitney Bowes claim described above, as is customary with
technology companies, we may receive or become aware of correspondence claiming
potential infringement of other parties' intellectual property rights. We could
incur significant costs and diversion of management time and resources to defend
claims against us regardless of their validity. We may not have adequate
resources to defend against these claims and any associated costs and
distractions could have a material adverse effect on our business, financial
condition and results of operations. As an alternative to litigation, we may
seek licenses for other parties' intellectual property rights. We may not be
successful in obtaining all of the necessary licenses on commercially reasonable
terms, if at all. Any loss resulting from intellectual property litigation could
severely limit our operations, cause us to pay license fees, or prevent us from
doing business.

A failure to protect our own intellectual property could harm our competitive
position.

     We rely on a combination of patent, trade secret, copyright and trademark
laws and contractual restrictions to establish and protect our rights in our
products, services, know-how and information. We have three issued US patents
and have filed 40 patent applications in the United States, and one
international patent application. We have also applied to register a number of
trademarks and service marks. We plan to apply for other patents, trademarks and
service marks in the future. We may not receive patents for any of our patent
applications. Even if patents are issued to us, claims issued in these patents
may not protect our technology. In addition, any of our patents, trademarks or
service marks might be held invalid or unenforceable by a court. If our patents
fail to protect our technology or our trademarks and service marks are
successfully challenged, our competitive position could be harmed. Even if our
patents are upheld or are not challenged, third parties may develop alternative
technologies or products without infringing our patents.

     We generally enter into confidentiality agreements with our employees,
consultants and other third parties to control and limit access and disclosure
of our confidential information. These contractual arrangements or other steps
taken to protect our intellectual property may not prove to be sufficient to
prevent misappropriation of technology or deter independent third party
development of similar technologies. Additionally, the laws of foreign countries
may not protect our services or intellectual property rights to the same extent
as do the laws of the United States.

Our growth and operating results could be impaired if we are unable to meet our
future capital requirements.

     We believe that our current cash balances will allow us to fund our
operations through fiscal year 2001. However, we may require substantial working
capital to fund our business and we may need to raise additional capital. We
cannot be certain that additional funds will be available on satisfactory terms
when needed, if at all. Our future capital needs depend on many factors,
including market acceptance of our postage and shipping services; the level of
promotion and advertising of our postage and shipping services; the level of our
development efforts; rate of customer acquisition and retention of our postage
and shipping services; and changes in technology.

     The various elements of our business and growth strategies, including our
plans to support fully the commercial release of our service, our introduction
of new products and services and our investments in infrastructure will require
additional capital. If we are unable to raise additional necessary capital in
the future, we may be required to curtail our operations significantly or obtain
funding through the relinquishment of significant technology or markets. Also,
raising additional equity capital would have a dilutive effect on existing
stockholders.

We could be required to register as an investment company and become subject to
substantial regulation that would interfere with our ability to conduct our
business.

     We invest in short-term instruments consistent with prudent cash management
and not primarily for the purpose of achieving investment returns. This could
result in our being treated as an investment company under the Investment
Company Act of 1940 and therefore being required to register as an investment
company under the Investment Company Act. The Investment Company Act requires
the registration of companies which are engaged primarily in the business of
investing, reinvesting or trading in securities or

                                       16
<PAGE>

which are engaged in investing, reinvesting, owning, holding or trading in
securities and over 40% of whose assets on an unconsolidated basis (other than
government securities and cash) consist of investment securities. While we do
not believe that we are engaged primarily in the business of investing,
reinvesting or trading in securities, we may invest our cash and cash
equivalents in government securities to the extent necessary to avoid having
over 40% of our assets consist of investment securities. Government securities
are defined as securities issued by the U.S. government and certain federal
agencies. These securities generally yield lower rates of income than other
short-term instruments in which we have invested to date. Accordingly, investing
substantially all of our cash and cash equivalents in government securities
could result in lower levels of interest income, which could cause our losses to
increase.

     If we were required to register as an investment company under the
Investment Company Act, we would become subject to substantial regulation with
respect to our capital structure, management, operations, transactions with
affiliated persons, if any, and other matters, incur substantial costs and
experience a disruption of our business. Application of the provisions of the
Investment Company Act to us would materially and adversely affect our business,
prospects, financial condition and results of operations.

If the software, hardware, computer technology and other systems and services we
use are not Year 2000 compliant, our operations could suffer and we could lose
customers.

     Many existing computer systems and software products are coded to accept
only two digit entries in the date code field and cannot distinguish 21st
century dates from 20th century dates. If these systems have not been properly
corrected, there could be system failures or miscalculations causing disruptions
of operations, including, among other things, a temporary inability to process
transactions or engage in normal business activities. As a result, many
companies' software and computer systems may need to be upgraded or replaced to
become "Year 2000" compliant. In addition, despite the fact that many computer
systems are currently processing 21st century dates correctly, these companies,
including us, could experience latent Year 2000 problems.

     We use and depend on third party equipment and software that may not be
Year 2000 compliant. If Year 2000 issues prevent our customers from accessing
the Internet or our Web site, processing transactions or using their credit
cards, our business will suffer. Any failure of our third party equipment,
software or services to operate properly could require us to incur unanticipated
expenses, which could seriously harm our business and operating results.

                   We face risks associated with our market

If we do not respond effectively to technological change, our services could
become obsolete and our business will suffer.

     The development of our services and other technology entails significant
technical and business risks. To remain competitive, we must continue to enhance
and improve the responsiveness, functionality and features of our online
operations. The Internet and the electronic commerce industry are characterized
by rapid technological change; changes in user and customer requirements and
preferences; frequent new product and service introductions embodying new
technologies; and the emergence of new industry standards and practices.

     The evolving nature of the Internet or the Internet postage and shipping
markets could render our existing technology and systems obsolete. Our success
will depend, in part, on our ability to license or acquire leading technologies
useful in our business; enhance our existing services; develop new services or
features and technology that address the increasingly sophisticated and varied
needs of our current and prospective users; and respond to technological
advances and emerging industry and regulatory standards and practices in a cost-
effective and timely manner.

     Future advances in technology may not be beneficial to, or compatible with,
our business. Furthermore, we may not be successful in using new technologies
effectively or adapting our technology and systems to user requirements or
emerging industry standards on a timely basis. Our ability to remain
technologically competitive may require substantial expenditures and lead time.
If we are unable to adapt in a timely manner to changing market conditions or
user requirements, our business, financial condition and results of operations
could be seriously harmed.

If we are unable to compete successfully, particularly against large,
traditional providers of postage products such as Pitney Bowes who enter the
online postage and shipping markets, our revenues and operating results will
suffer.

     The market for Internet postage products and services is new and we expect
it to be intensely competitive. At present, E-Stamp has a hardware-based product
commercially available and has announced that it begun testing a Web-based
product through the

                                       17
<PAGE>

Information Based Indicia Program. Pitney Bowes has a software-based product
commercially available and has a hardware-based product in beta testing. Neopost
Industries has hardware and software products in beta testing. If any of our
competitors, including Pitney Bowes, provide the same or similar service as we
provide, our operations could be adversely impacted. See "Business--
Competition."

     Internet postage may not be adopted by customers. These customers may
continue to use traditional means to purchase postage, including purchasing
postage from their local post office. If Internet postage becomes a viable
market, we may not be able to establish or maintain a competitive position
against current or future competitors as they enter the market. Many of our
competitors have longer operating histories, larger customer bases, greater
brand recognition, greater financial, marketing, service, support, technical,
intellectual property and other resources than us. As a result, our competitors
may be able to devote greater resources to marketing and promotional campaigns,
adopt more aggressive pricing policies and devote substantially more resources
to Web site and systems development than us. This increased competition may
result in reduced operating margins, loss of market share and a diminished
brand. We may from time to time make pricing, service or marketing decisions or
acquisitions as a strategic response to changes in the competitive environment.
These actions could result in reduced margins and seriously harm our business.

     If the market for Internet postage develops, we could face competitive
pressures from new technologies or the expansion of existing technologies
approved for use by the US Postal Service. We may also face competition from a
number of indirect competitors that specialize in electronic commerce and other
companies with substantial customer bases in the computer and other technical
fields. Additionally, companies that control access to transactions through a
network or Web browsers could also promote our competitors or charge us a
substantial fee for inclusion. Our competitors may also be acquired by, receive
investments from or enter into other commercial relationships with larger,
better-established and better-financed companies as use of the Internet and
other online services increases. In addition, changes in postal regulations
could adversely affect our service and significantly impact our competitive
position. We may be unable to compete successfully against current and future
competitors, and the competitive pressures we face could seriously harm our
business.

     As a result of the iShip.com acquisition in March 2000, we also compete
with companies that provide shipping solutions to businesses. Customers may
continue using the direct services of the US Postal Service, UPS and other major
shippers, instead of adopting our online service. Alternatively, potential
competitors with greater resources than Stamps.com, like Pitney Bowes, may
develop more successful Internet solutions. In addition, companies including
TanData Corporation, GoShip.com, BITS, Inc./Intershipper.net, Kewill Systems,
PackageNet and Virtan, Inc./SmartShip are competing in shipping services. We
also face a significant risk that large shipping companies will collaborate in
the development and operation of an online shipping system that could make our
Internet shipping services obsolete.

The success of our business will depend on the continued growth of the Internet
and the acceptance by customers of the Internet as a means for purchasing
postage and shipping services.

     Our success depends in part on widespread acceptance and use of the
Internet as a way to purchase postage and shipping services. This practice is at
an early stage of development, and market acceptance of Internet postage and
shipping services is uncertain. We cannot predict the extent to which customers
will be willing to shift their purchasing habits from traditional to online
postage and/or shipping services. To be successful, our customers must accept
and utilize electronic commerce to satisfy their product needs. Our future
revenues and profits, if any, substantially depend upon the acceptance and use
of the Internet and other online services as an effective medium of commerce by
our target users.

     The Internet may not become a viable long-term commercial marketplace due
to potentially inadequate development of the necessary network infrastructure or
delayed development of enabling technologies and performance improvements. The
commercial acceptance and use of the Internet may not continue to develop at
historical rates. Our business, financial condition and results of operations
would be seriously harmed if use of the Internet and other online services does
not continue to increase or increases more slowly than expected; the
infrastructure for the Internet and other online services does not effectively
support future expansion of electronic commerce or our services; concerns over
security and privacy inhibit the growth of the Internet; or the Internet and
other online services do not become a viable commercial marketplace.

US Postal Service regulation may cause disruptions or the discontinuance of our
business. Additionally, the US Postal Service could assess fees that would
increase the cost of our service and possibly affect the adoption of Internet
postage as a new method of mailing.

     We are subject to continued US Postal Service scrutiny and other government
regulations. The US Postal Service could change its certification requirements
or specifications for Internet postage or revoke the approval of our service at
any time. Any changes in

                                       18
<PAGE>

requirements or specifications for Internet postage could adversely affect our
pricing, cost of revenues, operating results and margins by increasing the cost
of providing our Internet postage service. For example, the US Postal Service
could decide to charge Internet postage vendors fees for the enrollment of each
unique customer of the Internet postage product, which would be a cost that we
would either absorb or pass through to customers. The US Postal Service has in
fact invoiced each Internet postage vendor $8 for each digital certificate
required for each consumer of Internet postage to securely print postage. We are
currently discussing the necessity of this charge with the US Postal Service. If
we are required to pay this per customer charge, the cost of our service could
increase and the adoption of Internet postage as a new method of mailing could
be adversely affected.

     The US Postal Service could also decide that Internet postage should no
longer be an approved postage service due to security concerns or other issues.
Our business would suffer dramatically if we are unable to adapt our Internet
Postage service to any new requirements or specifications or if the US Postal
Service were to discontinue Internet postage as an approved postage method.
Alternatively, the US Postal Service could introduce competitive programs or
amend Internet postage requirements to make certification easier to obtain,
which could lead to more competition from third parties or the US Postal Service
itself. See "Risk Factors--If we are unable to compete successfully,
particularly against large, traditional providers of postage products like
Pitney Bowes who enter the online postage and shipping markets, our revenues and
operating results will suffer."

     In addition, US Postal Service regulations may require that our personnel
with access to postal information or resources receive security clearance prior
to doing relevant work. We may experience delays or disruptions if our personnel
cannot receive necessary security clearances in a timely manner, if at all. The
regulations may limit our ability to hire qualified personnel. For example,
sensitive clearance may only be provided to US citizens or aliens who are
specifically approved to work on US Postal Service projects.

Our operating results could be impaired if we or the Internet become subject to
additional government regulation and legal uncertainties.

     With the exception of US Postal Service and Department of Commerce
regulations, we are not currently subject to direct regulation by any domestic
or foreign governmental agency, other than regulations applicable to businesses
generally, and laws or regulations directly applicable to electronic commerce.
However, due to the increasing popularity and use of the Internet, it is
possible that a number of laws and regulations may be adopted with respect to
the Internet, relating to user privacy; pricing; content; copyrights;
distribution; characteristics and quality of products and services; and export
controls.

     The adoption of any additional laws or regulations may hinder the expansion
of the Internet. A decline in the growth of the Internet could decrease demand
for our products and services and increase our cost of doing business. Moreover,
the applicability of existing laws to the Internet is uncertain with regard to
many issues, including property ownership, export of specialized technology,
sales tax, libel and personal privacy. Our business, financial condition and
results of operations could be seriously harmed by any new legislation or
regulation. The application of laws and regulations from jurisdictions whose
laws do not currently apply to our business, or the application of existing laws
and regulations to the Internet and other online services could also harm our
business.

     We offer our services in multiple states and plan to expand both
domestically and internationally. These jurisdictions may claim that we are
required to qualify to do business as a foreign corporation in each state or
foreign country. Our failure to qualify as a foreign corporation in a
jurisdiction where we are required to do so could subject us to taxes and
penalties. Other states and foreign countries may also attempt to regulate our
services or prosecute us for violations of their laws. Further, we might
unintentionally violate the laws of foreign jurisdictions and those laws may be
modified and new laws may be enacted in the future.

If we market our services internationally, government regulation could disrupt
our operations.

     One element of our strategy is to provide services in international
markets. Our ability to provide our Internet Postage service in international
markets would likely be subject to rigorous governmental approval and
certification requirements similar to those imposed by the US Postal Service.
For example, our Internet Postage service cannot currently be used for
international mail because foreign postal authorities do not currently recognize
information-based indicia postage. If foreign postal authorities accept postage
generated by our service in the future, and if we obtain the necessary foreign
certification or approvals, we would be subject to ongoing regulation by foreign
governments and agencies. To date, efforts to create a certification process in
Europe and other foreign markets are in a preliminary stage and these markets
may not prove to be a viable opportunity for us. As a result, we cannot predict
when, or if, international markets will become a viable source of revenues for a
postage service similar to ours.

     Our ability to provide service in international markets may also be
impacted by the export control laws of the United States. Our software
technology makes us subject to stronger export controls, and may prevent us from
being able to export our products and

                                       19
<PAGE>

services. Regulations and standards of the Universal Postal Union and other
international bodies may also limit our ability to provide international mail
services.

     If we achieve significant international acceptance of our services, our
business activities will be subject to a variety of potential risks, including
the adoption of laws and regulatory requirements, political and economic
conditions, difficulties protecting our intellectual property rights and actions
by third parties that would restrict or eliminate our ability to do business in
these jurisdictions. If we begin to transact business in foreign currencies, we
will become subject to the risks attendant to transacting in foreign currencies,
including the potential adverse effects of exchange rate fluctuations.

Our charter documents could deter a takeover effort, which could inhibit your
ability to receive an acquisition premium for your shares.

     The provisions of our Amended and Restated Certificate of Incorporation,
Bylaws and Delaware law could make it difficult for a third party to acquire us,
even it would be beneficial to our stockholders. In addition, we are subject to
the provisions of Section 203 of the Delaware General Corporation Law, which
could prohibit or delay a merger or other takeover of our company, and
discourage attempts to acquire us.

Additional shares held by existing stockholders may be sold into the public
market, which could cause our stock price to decline.

     Public sales of substantial amounts of common stock purchased in private
financings prior to our initial public offering or upon the exercise of stock
options or warrants could adversely affect the prevailing market price of our
common stock. On December 22, 1999, upon the expiration of a lock-up entered
into in connection with our initial public offering, an additional 2.1 million
shares of our outstanding common stock were available for immediate sale. On
February 7, 2000, a lock-up entered into in connection with our follow-on public
offering expired for approximately 6.8 million shares of our outstanding common
stock and, on March 6, 2000, the follow-on offering lock-up expired for all
remaining shares subject to the lock-up. All of the shares subject to the lock-
up were available for immediate sale, subject to the volume and other
restrictions under Rule 144 of the Securities Act of 1933. Of these shares,
approximately 22.5 million held by investment funds may be distributed by them
from time to time to their investors. Upon distribution, those shares will be
available for immediate sale.

     Sales of substantial amounts of common stock in the public market, or the
perception that these sales could occur, could adversely affect the prevailing
market price for our common stock and could impair our ability to raise capital
through a public offering of equity securities.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk.

     We are exposed to interest rate risk from the short-term investments and
line of credit. At March 31, 2000, the short-term investments, which consist
principally of corporate debt and commercial paper, approximated $330.7 million
and had a related weighted average interest rate of 6.3%. At March 31, 2000, the
line of credit balance totaled $1 million and the related interest rate was 9.5%
(the bank's prime rate plus 1%).

     If market interest rates continue to rise, the value of the short-term
investments will continue to decrease. We currently hold no derivative
instruments and do not earn foreign-source income. We expect to invest only in
short-term, investment grade and interest-bearing instruments.

                                    PART II
                               OTHER INFORMATION

Item 1.  Legal Proceedings.

     On June 16, 1999, Pitney Bowes sued us for alleged patent infringement in
the United States District Court for the District of Delaware. The suit alleges
that we are infringing two patents held by Pitney Bowes related to postage
application systems and electronic indicia. The suit seeks treble damages, a
preliminary and permanent injunction from further alleged infringement,
attorneys' fees and other unspecified damages. We answered the complaint on
August 6, 1999, denying the allegations of patent infringement and asserting a
number of affirmative defenses. Pitney Bowes filed a similar complaint in early
June 1999 against one of our competitors, E-Stamp Corporation, alleging
infringement of seven Pitney Bowes patents. On April 13, 2000, Pitney Bowes
asked the court for permission to amend its complaint to drop allegations of
patent infringement with respect to one patent and to add allegations of patent
infringement with respect to three other patents.

     The outcome of the litigation that Pitney Bowes has brought against us is
uncertain. Therefore, we can give no assurance that Pitney Bowes will not
prevail in its suit against us. See "Risk Factors--Success by Pitney Bowes in
its suit against us alleging patent infringement could prevent us from offering
our Internet Postage service and severely harm our business or cause it to
fail."

     On December 29, 1999, three individual plaintiffs filed a suit against us
for alleged breach of oral contract, quantum meruit, fraud and negligent
representation in the California Superior Court for the County of Los Angeles.
The complaint was amended on January 28, 2000 to add Mohan Ananda, one of our
directors, as a defendant and to remove one of the plaintiffs from the suit. The
suit alleges that the plaintiffs were due cash consideration for securing a
board member and investors for Stamps.com. The complaint seeks $13.3 .million
plus other unspecified compensatory damages, punitive and exemplary damages and
attorneys' fees and costs incurred. We answered the complaint on March 8, 2000,
denying the allegations and asserting a number of affirmative defenses. The
outcome of this litigation is uncertain and we can give no assurance that the
plaintiffs will not prevail.

     We are not currently involved in any other material legal proceedings, nor
have we been involved in any such proceeding that has had or may have a
significant effect on our company. We are not aware of any other material legal
proceedings pending against us.

Item 2.  Changes in Securities and Use of Proceeds.

     (d) Use of Proceeds from Sales of Registered Securities.

     On June 30,1999, we completed an initial public offering of 5,000,000
shares of common stock pursuant to our Registration Statement on Form S-1 (File
No. 333-77025) that was declared effective by the Securities and Exchange
Commission on June 24, 1999.  On July 8, 1999, we sold an additional 750,000
shares of common stock pursuant to the exercise of the underwriters' over-
allotment option.  There has been no material change with respect to our use of
proceeds from our initial public offering to the information discussed in our
Quarterly Report on Form 10-Q for the period ended June 30, 1999 and all of the
net proceeds from our initial public offering have been applied.

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

     iShip.com, Inc., a Washington corporation (the "Company"), for value
                                                     -------
received, hereby certifies that Imperial Bancorp or its registered assigns (the

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

              (i)  In lieu of exercising this Warrant in the manner provided
above in Section 1(a), the Registered Holder may elect to receive shares equal
to the value of this Warrant (or the portion thereof being canceled) by
surrender of this Warrant at the principal office of the Company together with
notice of such election in which event the Company shall issue to holder a
number of shares of Common Stock computed using the following formula:

                   X =   Y (A - B)
                         ---------
                             A

Where     X = The number of shares of Common Stock to be issued to the
               Registered Holder.

          Y = The number of shares of Common Stock purchasable under this
               Warrant (at the date of such calculation).

          A = The fair market value of one share of Common Stock (at the date of
               such calculation).

          B = The Purchase Price (as adjusted to the date of such calculation).

              (ii) For purposes of this Section 1(c), the fair market value of
one share of Common Stock on the date of calculation shall mean:

                   (A)  if the exercise is in connection with an initial public
offering of the Company's Common Stock, and if the Company's Registration
Statement relating to such public offering has been declared effective by the
Securities and Exchange Commission, then the fair market value per share of
Common Stock shall be the initial "Price to Public" specified in the final
prospectus with respect to the offering;

                   (B)  if this Warrant is exercised after, and not in
connection with, the Company's initial public offering, and if the Company's
Common Stock is traded on a securities exchange or The Nasdaq Stock Market or
actively traded over-the-counter:

                                      -2-
<PAGE>

                        (1)  if the Company's Common Stock is traded on a
securities exchange or The Nasdaq Stock Market, the fair market value shall be
deemed to be the average of the closing prices over a thirty (30) day period
ending three days before date of calculation; or

                        (2)  if the Company's Common Stock is actively traded
over-the-counter, the fair market value shall be deemed to be the average of the
closing bid or sales price (whichever is applicable) over the thirty (30) day
period ending three days before the date of calculation; or

                   (C)  if neither (A) nor (B) is applicable, the fair market
value shall be at the highest price per share which the Company could obtain on
the date of calculation from a willing buyer (not a current employee or
director) for shares of Common Stock sold by the Company, from authorized but
unissued shares, as determined in good faith by the Board of Directors, unless
the Company is at such time subject to an acquisition as described in Section
5(b) below, in which case the fair market value per share of Common Stock shall
be deemed to be the value of the consideration per share received by the holders
of such stock pursuant to such acquisition.

          (d) Delivery to Holder.  As soon as practicable after the exercise of
              ------------------
this Warrant in whole or in part, and in any event within ten (10) days
thereafter, the Company at its expense will cause to be issued in the name of,
and delivered to, the Registered Holder, or as such Holder (upon payment by such
Holder of any applicable transfer taxes) may direct:

              (i)  a certificate or certificates for the number of shares of
Warrant Stock to which such Registered Holder shall be entitled, and

              (ii) in case such exercise is in part only, a new warrant or
warrants (dated the date hereof) of like tenor, calling in the aggregate on the
face or faces thereof for the number of shares of Warrant Stock equal (without
giving effect to any adjustment therein) to the number of such shares called for
on the face of this Warrant minus the number of such shares purchased by the
Registered Holder upon such exercise as provided in Section 1(a) above.

     2.   Adjustments.
          -----------

          (a)  Stock Splits and Dividends.  If outstanding shares of the
               --------------------------
Company's Common Stock shall be subdivided into a greater number of shares or a
dividend in Common Stock shall be paid in respect of Common Stock, the Purchase
Price in effect immediately prior to such subdivision or at the record date of
such dividend shall simultaneously with the effectiveness of such subdivision or
immediately after the record date of such dividend be proportionately reduced.
If outstanding shares of Common Stock shall be combined into a smaller number of
shares, the Purchase Price in effect immediately prior to such combination
shall, simultaneously with the effectiveness of such combination, be
proportionately increased.  When any adjustment is required to be made in the
Purchase Price, the number of shares of Warrant Stock purchasable upon the
exercise of this Warrant shall be changed to the number determined by dividing
(i) an amount equal to the number of shares issuable upon the exercise of

                                      -3-
<PAGE>

this Warrant immediately prior to such adjustment, multiplied by the Purchase
Price in effect immediately prior to such adjustment, by (ii) the Purchase Price
in effect immediately after such adjustment.

          (b) Reclassification, Reorganization or Acquisition. In case there
              -----------------------------------------------
occurs, on or after the date hereof, (i) any reclassification or change of the
outstanding securities of the Company or of any reorganization of the Company
(or any other corporation the stock or securities of which are at the time
receivable upon the exercise of this Warrant) or any similar corporate
reorganization, (ii) a merger or consolidation of the Company or similar
acquisition transaction as a result of which shareholders of the Company
immediately prior to such acquisition possess a minority of the voting power of
the acquiring entity immediately following such transaction, or (iii) the sale
of all or substantially all of the Company's properties and assets to any other
person, then and in each such case the Registered Holder, upon the exercise
hereof at any time after the consummation of such reclassification, change,
reorganization, merger or sale, shall be entitled to receive, in lieu of the
stock or other securities and property receivable upon the exercise hereof prior
to such consummation, the stock or other securities or property to which such
holder would have been entitled upon such consummation if such holder had
exercised this Warrant immediately prior thereto, all subject to further
adjustment pursuant to the provisions of this Section 2.

          (c) Adjustment Certificate.  When any adjustment is required to be
              ----------------------
made in the Warrant Stock or the Purchase Price pursuant to this Section 2, the
Company shall promptly mail to the Registered Holder a certificate setting forth
(i) a brief statement of the facts requiring such adjustment, (ii) the Purchase
Price after such adjustment and (iii) the kind and amount of stock or other
securities or property into which this Warrant shall be exercisable after such
adjustment.

     3.   Transfers.
          ---------

          (a) Unregistered Security.  Each holder of this Warrant acknowledges
              ---------------------
that this Warrant and the Warrant Stock have not been registered under the
Securities Act of 1933, as amended (the "Securities Act"), and agrees not to
                                         --------------
sell, pledge, distribute, offer for sale, transfer or otherwise dispose of this
Warrant or any Warrant Stock issued upon its exercise in the absence of (i) an
effective registration statement under the Act as to this Warrant or such
Warrant Stock and registration or qualification of this Warrant or such Warrant
Stock under any applicable U.S. federal or state securities law then in effect
or (ii) an opinion of counsel, satisfactory to the Company, that such
registration and qualification are not required.  Each certificate or other
instrument for Warrant Stock issued upon the exercise of this Warrant shall bear
a legend substantially to the foregoing effect.

          (b) Transferability. Subject to the provisions of Section 3(a) hereof,
              ---------------
this Warrant and all rights hereunder are transferable: (i) to an assignee of
the Registered Holder's interest in that certain Loan and Security Agreement
between the Registered Holder and the Company dated as of the date hereof; or
(ii) with the consent of the Company, which consent shall not be unreasonably
withheld, to any other individual or entity; provided that in either case
                                             --------

                                      -4-
<PAGE>

any assignee shall be bound by the terms hereof. Notwithstanding the foregoing,
this Warrant may not be transferred to any individual or entity engaged in any
business that competes with any business of the Company, and any purported
transfer to a such an individual or entity shall be void. A permitted transfer
of this Warrant shall be effected by surrendering the Warrant with a properly
executed assignment (in the form of Exhibit B hereto) at the principal office of
                                    ---------
the Company.  This Warrant may not be transferred in part.

          (c) Warrant Register.   The Company will maintain a register
              ----------------
containing the names and addresses of the Registered Holders of this Warrant.
Until any transfer of this Warrant is made in the warrant register, the Company
may treat the Registered Holder of this Warrant as the absolute owner hereof for
all purposes; provided, however, that if this Warrant is properly assigned in
              --------  -------
blank, the Company may (but shall not be required to) treat the bearer hereof as
the absolute owner hereof for all purposes, notwithstanding any notice to the
contrary.  Any Registered Holder may change such Registered Holder's address as
shown on the warrant register by written notice to the Company requesting such
change.

     4.   Representations and Warranties of Holder.  The Registered Holder
          ----------------------------------------
hereby represents and warrants to the Company as follows:

          (a)  Purchase Entirely for Own Account. The Registered Holder
               ---------------------------------
acknowledges that this Warrant is given to the Registered Holder in reliance
upon the Registered Holder's representation to the Company, which by its
acceptance of this Warrant the Registered Holder hereby confirms, that the
Warrant, and the Warrant Shares (collectively, the "Securities") being acquired
                                                    ----------
by the Registered Holder are being acquired for investment for the Registered
Holder's own account, not as a nominee or agent, and not with a view to the
resale or distribution of any part thereof, and that the Registered Holder has
no present intention of selling, granting any participation in, or otherwise
distributing the same. By executing this Agreement, the Registered Holder
further represents that the Registered Holder does not presently have any
contract, undertaking, agreement or arrangement with any person to sell,
transfer or grant participations to such person or to any third person, with
respect to any of the Securities. The Registered Holder represents that it has
full power and authority to enter into this Agreement. The Registered Holder has
not been formed for the specific purpose of acquiring any of the Securities.

          (b)  Disclosure of Information.  The Registered Holder has had an
               -------------------------
opportunity to discuss the Company's business, management, financial affairs and
the terms and conditions of the offering of the Securities with the Company's
management and has had an opportunity to review the Company's facilities. The
Registered Holder understands that such discussions, as well as the written
information issued by the Company, were intended to describe the aspects of the
Company's business which it believes to be material.

          (c)  Restricted Securities. The Registered Holder understands that the
               ---------------------
Securities have not been, and will not be, registered under the Securities Act,
by reason of a specific exemption from the registration provisions of the
Securities Act which depends upon, among other things, the bona fide nature of
the investment intent and the accuracy of the

                                      -5-
<PAGE>

Registered Holder's representations as expressed herein. The Registered Holder
understands that the Securities are "restricted securities" under applicable
U.S. federal and state securities laws and that, pursuant to these laws, the
Registered Holder must hold the Securities indefinitely unless they are
registered with the Securities and Exchange Commission and qualified by state
authorities, or an exemption from such registration and qualification
requirements is available. the Registered Holder acknowledges that the Company
has no obligation to register or qualify the Securities for resale. The
Registered Holder further acknowledges that if an exemption from registration or
qualification is available, it may be conditioned on various requirements
including, but not limited to, the time and manner of sale, the holding period
for the Securities, and on requirements relating to the Company which are
outside of the Registered Holder's control, and which the Company is under no
obligation and may not be able to satisfy.

          (d) No Public Market.  The Registered Holder understands that no
              ----------------
public market now exists for any of the securities issued by the Company, that
the Company has made no assurances that a public market will ever exist for the
Securities.

          (e)  Legends.  The Registered Holder understands that the Securities,
               -------
and any securities issued in respect of or exchange for the Securities, may bear
one or all of the following legends:

               (i)  "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN ACQUIRED FOR
INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR
DISTRIBUTION THEREOF. NO SUCH SALE OR DISTRIBUTION MAY BE EFFECTED WITHOUT AN
EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL IN A
FORM SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER
THE SECURITIES ACT OF 1933."

               (ii) Any legend required by the Blue Sky laws of any state to the
extent such laws are applicable to the shares represented by the certificate so
legended.

          (f)  Accredited Investor.    The Registered Holder is an accredited
               -------------------
investor as defined in Rule 501(a) of Regulation D promulgated under the Act.

     5.   No Impairment.  The Company will not, by amendment of its charter or
          -------------
through reorganization, consolidation, merger, dissolution, sale of assets or
any other voluntary action, avoid or seek to avoid the observance or performance
of any of the terms of this Warrant, but will at all times in good faith assist
in the carrying out of all such terms and in the taking of all such action as
may be necessary or appropriate in order to protect the rights of the holder of
this Warrant against impairment.

     6.   Termination.  This Warrant (and the right to purchase securities upon
          -----------
exercise hereof) shall terminate on the date that is five (5) years after the
issuance of this Warrent (the "Expiration Date").
                               ---------------

                                      -6-
<PAGE>

     7.   Notices of Certain Transactions.  In case:
          -------------------------------

          (a) the Company shall take a record of the holders of its Common Stock
(or other stock or securities at the time deliverable upon the exercise of this
Warrant) for the purpose of entitling or enabling them to receive any dividend
or other distribution, or to receive any right to subscribe for or purchase any
shares of stock of any class or any other securities, or to receive any other
right, to subscribe for or purchase any shares of stock of any class or any
other securities, or to receive any other right, or

          (b) of any capital reorganization of the Company, any reclassification
of the capital stock of the Company, any consolidation or merger of the Company,
any consolidation or merger of the Company with or into another corporation
(other than a consolidation or merger in which the Company is the surviving
entity), or any transfer of all or substantially all of the assets of the
Company, or

          (c) of the voluntary or involuntary dissolution, liquidation or
winding-up of the Company,

then, and in each such case, the Company will mail or cause to be mailed to the
Registered Holder of this Warrant a notice specifying, as the case may be, (i)
the date on which a record is to be taken for the purpose of such dividend,
distribution or right, and stating the amount and character of such dividend,
distribution or right, or (ii) the effective date on which such reorganization,
reclassification, consolidation, merger, transfer, dissolution, liquidation or
winding-up is to take place, and the time, if any is to be fixed, as of which
the holders of record of Common Stock (or such other stock or securities at the
time deliverable upon such reorganization, reclassification, consolidation,
merger, transfer, dissolution, liquidation or winding-up) are to be determined.
Such notice shall be mailed at least ten (10) days prior to the record date or
effective date for the event specified in such notice.

     8.  Reservation of Stock.  The Company will at all times reserve and keep
         --------------------
available, solely for the issuance and delivery upon the exercise of this
Warrant, such shares of Warrant Stock and other stock, securities and property,
as from time to time shall be issuable upon the exercise of this Warrant.

     9.  Exchange of Warrants.  Upon the surrender by the Registered Holder of
         --------------------
any Warrant or Warrants, properly endorsed, to the Company at the principal
office of the Company, the Company will, subject to the provisions of Section 3
hereof, issue and deliver to or upon the order of such Holder, at the Company's
expense, a new Warrant or Warrants of like tenor, in the name of such Registered
Holder or as such Registered Holder (upon payment by such Registered Holder of
any applicable transfer taxes) may direct, calling in the aggregate on the face
or faces thereof for the number of shares of Common Stock called for on the face
or faces of the Warrant or Warrants so surrendered.

     10.  Replacement of Warrants.  Upon receipt of evidence reasonably
          -----------------------
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and (in the case of loss, theft or destruction) upon delivery of an
indemnity agreement (with surety if reasonably

                                      -7-
<PAGE>

required) in an amount reasonably satisfactory to the Company, or (in the case
of mutilation) upon surrender and cancellation of this Warrant, the Company will
issue, in lieu thereof, a new Warrant of like tenor.

     11.  Notices.  Any notice required or permitted by this Warrant shall be in
          -------
writing and shall be deemed sufficient upon receipt, when delivered personally
or by courier, overnight delivery service or confirmed facsimile, or forty-eight
(48) hours after being deposited in the regular mail as certified or registered
mail (airmail if sent internationally) with postage prepaid, addressed (a) if to
the Registered Holder, to the address of the Registered Holder most recently
furnished in writing to the Company and (b) if to the Company, to the address
set forth below or subsequently modified by written notice to the Registered
Holder.

     12.  No Rights as Shareholder.  Until the exercise of this Warrant, the
          ------------------------
Registered Holder of this Warrant shall not have or exercise any rights by
virtue hereof as a shareholder of the Company.

     13.  No Fractional Shares.  No fractional shares of Common Stock will be
          --------------------
issued in connection with any exercise hereunder.  In lieu of any fractional
shares which would otherwise be issuable, the Company shall pay cash equal to
the product of such fraction multiplied by the fair market value of one share of
Common Stock on the date of exercise, as determined in good faith by the
Company's Board of Directors.

     14.  Amendment or Waiver.  Any term of this Warrant may be amended or
          -------------------
waived only by an instrument in writing signed by the party against which
enforcement of the amendment or waiver is sought.

     15.  Headings.  The headings in this Warrant are for purposes of reference
          --------
only and shall not limit or otherwise affect the meaning of any provision of
this Warrant.

     16.  Governing Law. This Warrant 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.

     17.  "Market Stand-Off" Agreement.  The Registered Holder hereby agrees
          ----------------------------
that, during the period of duration (up to, but not exceeding, 180 days)
specified by the Company and an underwriter of Common Stock or other securities
of the Company, following the effective date of a registration statement of the
Company filed under the Securities Act, it shall not, to the extent requested by
the Company and such underwriter, directly or indirectly sell, offer to sell,
contract to sell (including, without limitation, any short sale), grant any
option to purchase or otherwise transfer or dispose of (other than to donees who
agree to be similarly bound) any securities of the Company held by it at any
time during such period except Common Stock included in such registration;
provided, however, that:
- --------  -------

          (a) such agreement shall be applicable only during the two-year period
following the date of the final prospectus distributed pursuant to the first
such registration

                                      -8-
<PAGE>

statement of the Company which covers Common Stock (or other securities) to be
sold on its behalf to the public in an underwritten offering; and

          (b) all officers and directors of the Company, all one-percent
securityholders, and all other persons with registration rights (whether or not
pursuant to this Agreement) enter into similar agreements.

     In order to enforce the foregoing covenant, the Company may impose stop-
transfer instructions with respect to the Warrant Stock (and the shares or
securities of every other person subject to the foregoing restriction) until the
end of such period, and the Registered Holder agrees that, if so requested, such
Holder will execute an agreement in the form provided by the underwriter
containing terms which are essentially consistent with the provisions of this
Section 17.

To Whom It May Concern:

          This letter will serve to inform you that as of March 7, 2000 (the
"Closing Date"), Stamps.com Inc., a Delaware corporation ("Stamps"), assumed the

dated August 20, 1999, between Imperial Bank and iShip and all other related
agreements evidencing the option to purchase 10,000 shares of the common stock

amendments to the Warrant set forth herein.  The Warrant shall continue and
remain subject to the same terms and conditions after the Closing Date as were

                         Common Stock Purchase Warrant
                         -----------------------------

     Stamps.com Inc., a Delaware corporation ("Stamps.com"), hereby certifies
                                               ----------
that Mail Boxes Etc. USA, Inc. ("MBE"), or its registered assigns (collectively
                                 ---
with MBE, the "Registered Holder"), is entitled, upon the terms and subject to
               -----------------
the conditions set forth below, to purchase from Stamps.com, as set forth in
Section 1, at a purchase price of $6.07 per share, subject to adjustment in
accordance with the terms hereof, up to 658,986 shares of Common Stock of
Stamps.com ("Common Stock") subject to adjustment in accordance with the terms
             ------------
hereof.  The shares of Common Stock purchasable upon exercise of this Warrant
and the purchase price per share, as adjusted from time to time pursuant to the
provisions of this Warrant, are hereinafter referred to as the "Warrant Stock"
                                                                -------------
and the "Purchase Price," respectively.
         --------------

     This Warrant is issued pursuant to that certain Manifest System Services
and Co-Branding Agreement (the "Agreement") dated as of April 27, 1999 and
                                ---------
amended March 7, 2000 between iShip.com, Inc., a Washington corporation and
wholly owned subsidiary of Stamps.com, and MBE.  The terms of this Warrant, as
amended, were assumed by Stamps.com pursuant to the Acquisition (as defined in
Amendment No. 1 to the Agreement dated March 7, 2000).

     1.   Exercise.
          --------

          (a)  Manner of Exercise.  This Warrant may be exercised by the
               ------------------
Registered Holder, in whole or in part, at any time during the period commencing
on March 7, 2000 and ending on the Expiration Date (as defined in Section 5) by
surrendering this Warrant, with the purchase form appended hereto as Exhibit A
                                                                     ---------
duly executed by such Registered Holder or by such Registered Holder's duly
authorized attorney, at the principal office of Stamps.com, or at such other
office or agency as Stamps.com may designate, accompanied by payment in full of
the Purchase Price payable in respect of the number of shares of Warrant Stock
purchased upon such exercise.  The Purchase Price may be paid by cash, check,
wire transfer or by the surrender of
<PAGE>

promissory notes or other instruments representing indebtedness of Stamps.com to
the Registered Holder.

          (b)  Effective Time of Exercise.  Each exercise of this Warrant shall
               --------------------------
be deemed to have been effected immediately prior to the close of business on
the day on which this Warrant shall have been surrendered to Stamps.com as
provided in Section 1(a) above.  At such time, the person or persons in whose
name or names any certificates for Warrant Stock shall be issuable upon such
exercise as provided in Section 1(d) below shall be deemed to have become the
holder or holders of record of the Warrant Stock represented by such
certificates.

          (c)  Net Issue Exercise.
               ------------------

               (i)   In lieu of exercising this Warrant in the manner provided
above in Section 1(a), the Registered Holder may elect to receive shares equal
to the value of this Warrant (or the portion thereof being canceled) by
surrender of this Warrant at the principal office of Stamps.com together with
notice of such election in which event Stamps.com shall issue to such Holder a
number of shares of Warrant Stock computed using the following formula:

               X =  Y (A - B)
                    ---------
                         A

Where     X =  The number of shares of Warrant Stock to be issued to the
               Registered Holder.

          Y =  The number of shares of Warrant Stock purchasable under this
               Warrant (at the date of such calculation).

          A =  The fair market value of one share of Warrant Stock (at the date
               of such calculation).

          B =  The Purchase Price (as adjusted to the date of such calculation).

               (ii)  For purposes of this Section 1(c), the fair market value of
Warrant Stock on the date of calculation shall mean with respect to each share
of Warrant Stock:

                     (A) if Stamps.com's Common Stock is traded on a securities
exchange or The Nasdaq Stock Market or actively traded over-the-counter:

                         (1) if Stamps.com's Common Stock is traded on a
securities exchange or The Nasdaq Stock Market, the fair market value shall be
deemed to be the product of (x) the average of the closing prices over a ten
(10) trading day period, which period shall begin twelve (12) trading days prior
to the effective time of exercise of this Warrant and end three (3) trading days
prior to the effective day of exercise of this Warrant (i.e., if the Warrant is
effectively exercised on April 27, 2000, the period shall begin on April 10,
2000 and run through April 24, 2000) and (y) the number of shares of Common
Stock into which each share of Warrant Stock is convertible on such date; or

                                      -2-
<PAGE>

                         (2) if Stamps.com's Common Stock is actively traded
over-the-counter, the fair market value shall be deemed to be the product of (x)
the average of the closing bid or sales price (whichever is applicable) over a
ten (10) trading day period, which period shall begin twelve (12) trading days
prior to the effective time of exercise of this Warrant and end three (3)
trading days prior to the effective day of exercise of this Warrant (i.e., if
the Warrant is effectively exercised on April 27, 2000, the period shall begin
on April 10, 2000 and run through April 24, 2000) and (y) the number of shares
of Common Stock into which each share of Warrant Stock is convertible on such
date; or

                     (B)  if (A)(1) nor (A)(2) is applicable, the fair market
value of Warrant Stock shall be at the highest price per share which Stamps.com
could obtain on the date of calculation from a willing buyer (not a current
employee or director) for shares of Warrant Stock sold by Stamps.com, from
authorized but unissued shares, as agreed by Stamps.com and the holders of a
majority of the Warrant Stock issuable upon exercise of this Warrant, unless
Stamps.com is at such time subject to an acquisition, in which case the fair
market value of Warrant Stock shall be deemed to be the value received by the
holders of such stock pursuant to such acquisition and shall be valued on a
basis consistent with such acquisition consideration.

          (d)  Delivery to Holder.  As soon as practicable after the exercise of
               ------------------
this Warrant in whole or in part, and in any event within ten (10) days
thereafter, Stamps.com at its expense will cause to be issued in the name of,
and delivered to, the Registered Holder, or as such Holder (upon payment by such
Holder of any applicable transfer taxes) may direct:

               (i)   a certificate or certificates for the number of shares of
Warrant Stock to which such Registered Holder shall be entitled, and

               (ii)  in case such exercise is in part only, a new warrant or
warrants (dated the date hereof) of like tenor, calling in the aggregate on the
face or faces thereof for the number of shares of Warrant Stock equal (without
giving effect to any adjustment therein) to the number of such shares called for
in the introductory paragraph to this Warrant minus the number of such shares
purchased by the Registered Holder upon such exercise as provided in Section
1(a) or 1(c) above.

     2.   Adjustments.
          -----------

          (a)  Stock Splits and Dividends. If outstanding shares of Stamps.com's
               --------------------------
Common Stock shall be subdivided into a greater number of shares or a dividend
in Common Stock shall be paid in respect of Common Stock, the Purchase Price in
effect immediately prior to such subdivision or at the record date of such
dividend shall simultaneously with the effectiveness of such subdivision or
immediately after the record date of such dividend be proportionately reduced.
If outstanding shares of Common Stock shall be combined into a smaller number of
shares, the Purchase Price in effect immediately prior to such combination
shall, simultaneously with the effectiveness of such combination, be
proportionately increased.  When any adjustment is required to be made in the
Purchase Price, the number of shares of Warrant Stock purchasable upon the
exercise of this Warrant shall be changed to the number determined by dividing
(i) an amount equal to the number of shares issuable upon the exercise of

                                      -3-
<PAGE>

this Warrant immediately prior to such adjustment, multiplied by the Purchase
Price in effect immediately prior to such adjustment, by (ii) the Purchase Price
in effect immediately after such adjustment.

          (b)  Reclassification, Consolidation, Merger Etc.  In case at any time
               --------------------------------------------
or from time to time, Stamps.com shall (i) effect a reorganization (other than a
combination, reclassification, exchange or subdivision of shares, as otherwise
provided for herein), (ii) consolidate with or merge into any other entity or
person, or (iii) transfer all or substantially all of its properties or assets
to any other entity or person including under any plan or arrangement
contemplating the dissolution of Stamps.com, then, in each such case, as a part
of such reorganization, merger, consolidation, sale or transfer, lawful
provision shall be made so that the Registered Holder, on the exercise hereof as
provided in Section 1 at any time after the consummation of such reorganization,
consolidation, merger, sale or transfer or the effective date of such
reorganization, consolidation, merger, sale or transfer, as the case may be,
shall be entitled to receive, in lieu of the Common Stock (or other securities)
issuable on such exercise prior to such consummation or such effective date, the
stock and other securities and property (including cash) to which the Holder
would have been entitled upon such consummation or in connection with such
dissolution, as the case may be, if the Holder had so exercised this Warrant,
immediately prior thereto, all subject to further adjustment thereafter as
provided in this Section 2. Upon any reorganization, consolidation, merger, or
other such transaction referred to in this Section 2(b) (collectively, a
"Corporate Transaction"), this Warrant shall, immediately after such Corporate
Transaction, be appropriately adjusted to apply and pertain to the number and
class of securities which would have been issued to the Holder in the
consummation of such Corporate Transaction had the option been exercised
immediately prior to such Corporate Transaction.  Appropriate adjustments shall
also be made to the Purchase Price, provided the aggregate Purchase Price
payable hereunder shall remain the same.

          (c)  Adjustment Certificate.  When any adjustment is required to be
               ----------------------
made in the Warrant Stock or the Purchase Price pursuant to this Section 2,
Stamps.com shall promptly mail to the Registered Holder a certificate setting
forth (i) a brief statement of the facts requiring such adjustment, (ii) the
Purchase Price after such adjustment and (iii) the kind and amount of stock or
other securities or property into which this Warrant shall be exercisable after
such adjustment.

     3.   Transfers.
          ---------

          (a)  Unregistered Security.  Each holder of this Warrant acknowledges
               ---------------------
that this Warrant has not been registered under the Securities Act of 1933, as
amended (the "Securities Act"), and agrees not to sell, pledge, distribute,
              --------------
offer for sale, transfer or otherwise dispose of this Warrant, any Warrant Stock
issued upon its exercise or any Common Stock issued upon conversion of the
Warrant Stock in the absence of (i) an effective registration statement under
the Act as to this Warrant, such Warrant Stock or such Common Stock and
registration or qualification of this Warrant, such Warrant Stock or such Common
Stock under any applicable U.S. federal or state securities law then in effect,
or (ii) an opinion of counsel,

                                      -4-
<PAGE>

reasonably satisfactory to Stamps.com, that such registration and qualification
are not required. Each certificate or other instrument for Warrant Stock issued
upon the exercise of this Warrant shall bear a legend substantially to the
foregoing effect.

          (b)  Transferability. This Warrant may not be transferred or assigned,
               ---------------
in whole or in part, by the Registered Holder except (i) to an affiliate of the
Registered Holder (provided that such affiliate agrees in writing with
Stamps.com and/or iShip.com to comply with Section 17 of the Agreement, as
amended) or (ii) where the Registered Holder has provided the Company with
written notice of its intent to assign or transfer the Warrant and the Company
has consented to such assignment or transfer in writing.  Any transfer in
accordance with the immediately preceding sentence shall be effected upon
surrender of the Warrant with a properly executed assignment (in the form of
Exhibit B hereto) at the principal office of Stamps.com.
- ---------

          (c)  Warrant Register.  Stamps.com will maintain a register containing
               ----------------
the names and addresses of the Registered Holders of this Warrant.  Until any
transfer of this Warrant is made in the warrant register, Stamps.com may treat
the Registered Holder of this Warrant as the absolute owner hereof for all
purposes; provided, however, that if this Warrant is properly assigned in blank,
          --------  -------
Stamps.com may (but shall not be required to) treat the bearer hereof as the
absolute owner hereof for all purposes, notwithstanding any notice to the
contrary.  Any Registered Holder may change such Registered Holder's address as
shown on the warrant register by written notice to Stamps.com requesting such
change.

     4.   No Impairment.  Stamps.com will not, by amendment of its charter or
          -------------
through reorganization, consolidation, merger, dissolution, sale of assets or
any other voluntary action, avoid or seek to avoid the observance or performance
of any of the terms of this Warrant, but will at all times in good faith assist
in the carrying out of all such terms and in the taking of all such action as
may be necessary or appropriate in order to protect the rights of the holder of
this Warrant against impairment.

     5.   Termination.
          -----------

          This Warrant (and the right to purchase securities upon exercise
hereof) shall terminate on April 27, 2004 (the "Expiration Date").
                                                ---------------

     6.   Notices of Certain Transactions.  In case:
          -------------------------------

          (a)  Stamps.com shall take a record of the holders of its Common Stock
(or other stock or securities at the time deliverable upon the exercise of this
Warrant) for the purpose of entitling or enabling them to receive any dividend
or other distribution, or to receive any right to subscribe for or purchase any
shares of stock of any class or any other securities, or to receive any other
right, to subscribe for or purchase any shares of stock of any class or any
other securities, or to receive any other right, or

          (b)  of any capital reorganization of Stamps.com, any reclassification
of the capital stock of Stamps.com, any consolidation or merger of Stamps.com,
any consolidation or merger of Stamps.com with or into another corporation
(other than a consolidation or merger in

                                      -5-
<PAGE>

which Stamps.com is the surviving entity), or any transfer of all or
substantially all of the assets of Stamps.com, or any other Corporate
Transaction, or

          (c)  of the voluntary or involuntary dissolution, liquidation or
winding-up of Stamps.com,

then, and in each such case, Stamps.com will mail or cause to be mailed to the
Registered Holder of this Warrant a notice specifying, as the case may be, (i)
the date on which a record is to be taken for the purpose of such dividend,
distribution or right, and stating the amount and character of such dividend,
distribution or right, or (ii) the effective date on which such reorganization,
reclassification, consolidation, merger, transfer, dissolution, liquidation,
winding-up, redemption or conversion is to take place, and the time, if any is
to be fixed, as of which the holders of record of Common Stock (or such other
stock or securities at the time deliverable upon such reorganization,
reclassification, consolidation, merger, transfer, dissolution, liquidation,
winding-up, redemption or conversion) are to be determined.  Such notice shall
be mailed at least twenty (20) days prior to the record date or effective date
for the event specified in such notice.

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

Warrant, such shares of Warrant Stock and other stock, securities and property,

     8.   Exchange of Warrants.  Upon the surrender by the Registered Holder of
          --------------------
any Warrant or Warrants, properly endorsed, to Stamps.com at the principal
office of Stamps.com, Stamps.com will, subject to the provisions of Section 3
hereof, issue and deliver to or upon the order of such Holder, at Stamps.com's
expense, a new Warrant or Warrants of like tenor, in the name of such Registered
Holder or as such Registered Holder (upon payment by such Registered Holder of
any applicable transfer taxes) may direct, calling in the aggregate on the face
or faces thereof for the number of shares of Common Stock called for on the face
or faces of the Warrant or Warrants so surrendered.

Warrant and (in the case of loss, theft or destruction) upon delivery of an
indemnity agreement (with surety if reasonably required) in an amount reasonably
satisfactory to Stamps.com, or (in the case of mutilation) upon surrender and
cancellation of this Warrant, Stamps.com will issue, in lieu thereof, a new

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

virtue hereof as a shareholder of Stamps.com.

     12.  No Fractional Shares.  No fractional shares of Common Stock will be
          --------------------
issued in connection with any exercise hereunder.  In lieu of any fractional

Stamps.com's Board of Directors.

                      STERLING PLAZA II - LEASE AGREEMENT


THIS LEASE is made and entered into this 7th day of March, 2000, by and between
STERLING REALTY ORGANIZATION CO., a Washington corporation ("Landlord"), and
iSHIP.COM, INC., a Washington corporation ("Tenant").

As parties hereto, Landlord and Tenant hereby agree as follows:


                               LEASE PROVISIONS

1.   Lease Provisions and Exhibits.

     (a)  Leased Premises.  The leased premises (the "Premises") are situated on
          ---------------
          the real property as more particularly described in Exhibit A attached
                                                              ---------
          hereto (the "Land"), and consists of those portions of the building
          located at 3545 Factoria Boulevard S.E. in Bellevue, King County,
          Washington, which are described in Section 1(b) below, which building
          is commonly known as Sterling Plaza II (the "Building"), which is part
          of a complex which will from time-to-time hereafter consist of one or
          more buildings, including the Building and related grounds and parking
          areas situated on the real property as more particularly described in
          Exhibit B attached hereto and shown thereon (the "Project").
          ---------

     (b)  Agreed Floor Areas.  Landlord and Tenant agree that the floor area of
          ------------------
          the Premises is approximately 75,510 rentable square feet, which area
          is comprised of the entire first, second, third and fourth floors of
          the Building.  Landlord and Tenant agree that the total floor area of
          the Building is approximately 92,866 rentable square feet.  Usable
          square feet shall be calculated according to Building Owners and
          Managers Association International ("BOMA") standards namely, the
          "Standard Method for Measuring Floor Area in Office Buildings ANSI -
          BOMA Z-65.1-1996".  Rentable square feet shall also be determined in
          accordance with BOMA based on the usable square footage measured,
          except that the load factor for the apportioned common area of the
          Building to be added to the usable area shall, for each full floor
          occupied by Tenant, not be greater than seven percent (7%), and for
          any partial floor occupied by Tenant, not be greater than ten percent
          (10%) (subject to adjustment following actual measurement of the
          Premises and the Building).  A floor plan of Premises is attached as
          Exhibit C.
          ---------

          Landlord and Tenant agree that (1) reasonable attempts have been made
          to determine the correct square footage used in this Lease based upon
          plans for the Building, and (2) exact square footage shall be
          determined following completion of the shell of the Building. Landlord
          shall, at such time, inform Tenant in writing of its calculation of
          exact square footage of the Premises and the Building. Landlord grants
          Tenant the option to re-measure and challenge the Premises square
          footage calculation, at Tenant's expense, within ninety (90) days
          after receipt of Landlord's calculation. If Tenant's square footage
          calculation differs from Landlord's calculation, Landlord will re-
          measure the Premises at Landlord's expense to determine which
          calculation is correct. Landlord and Tenant agree that any challenge
          of the square footage calculation must be carried out within ninety
          (90) days after the Commencement Date. Once the final areas of the
          Premises and Building have been so determined and agreed upon by
          Landlord and Tenant, rent, Tenant's Percentage of the Building, the
          Tenant Improvement Allowance, and all other amounts based on such
          areas shall be appropriately adjusted by written agreement between
          Landlord and Tenant. After such 90-day period has expired, Landlord
          and Tenant agree to mutually waive any and all rights, claims, or
          liabilities against one another as they relate to the calculation of
          square footage to determine rents and other costs in this Lease.

                                      -1-

     (c)  Addition to Agreed Floor Area of Premises; Cancellation of Sterling
          -------------------------------------------------------------------
          Plaza I Lease.  Tenant shall have until October 2, 2000, to
          -------------
          irrevocably notify Landlord in writing of Tenant's election to add the
          fifth floor of the Building, consisting of approximately 17,356
          rentable square feet, to the Premises by no later than April 15, 2001
          (as such date may be adjusted based on Landlord's substantial
          completion of the tenant improvements) (the "Fifth Floor Notice").  If
          Tenant has delivered the Fifth Floor Notice to Landlord prior to the
          end of business on October 2, 2000, then Tenant shall have until
          October 1, 2001, to provide Landlord with written notice of its
          election to cancel that certain lease between Landlord and Tenant
          dated July 15, 1999, relating to the Fifth Floor of Sterling Plaza I
          (the "Sterling Plaza I Lease").  Such cancellation must provide at
          least six (6) months notice of the termination date for the Sterling
          Plaza I Lease, but shall otherwise be without cost or penalty to
          Tenant.  If Tenant does not deliver the Fifth Floor Notice to Landlord
          by October 2, 2000, then Tenant must give Landlord written notice of
          its election to cancel the Sterling Plaza I Lease prior to the close
          of business on October 2, 2000, with such cancellation effective no
          sooner than April 2, 2001.  If Tenant fails to give Landlord such
          cancellation notice by October 2, 2000, then the Sterling Plaza I
          Lease shall remain in full force and effect for the remainder of its
          term.

     (d)  Tenant's Percentage of the Building.  "Tenant's Percentage of the
          -----------------------------------
          Building" is equal to 81.3%, calculated by dividing the number of
          rentable square feet in the Premises (75,510) by the number of
          rentable square feet in the Building (92,866).  Tenant's Percentage of
          the Building shall be appropriately adjusted as provided in Section
          1(b) above and at any time during this Lease that the area of the
          Premises or the Building changes.

     (e)  Lease Term.
          ----------

          (1)  Initial Lease Term.  The "Initial Lease Term" for the Premises
               ------------------
               will commence, on a floor-by-floor basis, fifteen (15) days
               following Landlord's substantial completion of the shell and core
               of the Building (as detailed on Exhibit D attached hereto) and
                                               ---------
               the tenant improvements (the scope of which is described on

               Exhibit E attached hereto), including without limitation the
               ---------
               following:

               (A)  the utility and other systems servicing the Building and
                    necessary for the operation of the Building or Tenant's
                    occupancy and full enjoyment of the Premises (such as
                    elevators, plumbing, heating, ventilating, air conditioning,
                    electrical and security systems) shall be completed and in
                    good order and operating condition except for details of
                    construction, decoration and mechanical adjustments which do
                    not materially interfere with Tenant's use of the Premises;

               (B)  The lobby of the Building and the entrances and public
                    portions (including the garage), stairways, corridors and
                    elevators (including freight elevators) of the Building
                    shall have been finished (except for details of
                    construction, decoration and mechanical adjustments which do
                    not materially detract from the appearance of such areas or
                    materially interfere with their use for normal purposes) and
                    shall be in a clean and orderly condition affording
                    reasonable access to all portions of the Premises;

               (C)  The exterior of the Building (including the installation of
                    glass therein) shall have been completed except for minor
                    portions thereof which in the aggregate do not materially
                    affect Tenant's use of the Premises; and

               (D)  the tenant improvements on such floor have been
                    substantially completed (meaning they are fully completed in
                    accordance with the approved plans and

                                      -2-
<PAGE>

                    specifications and ready for use by Tenant except for minor
                    punchlist items that do not materially affect Tenant's use
                    thereof).

               Additionally, Landlord shall have obtained a temporary
               Certificate of Occupancy for the Building and a temporary
               Certificate of Occupancy with respect to such floor of the
               Premises, each issued by the City of Bellevue.

               Tenant may use the fifteen (15) day period following substantial
               completion, as described above, to move its furniture and
               fixtures into the Premises.  Each such date, on a floor-by-floor
               basis, is the "Commencement Date."  The Initial Lease Term will
               expire on that date which is the last day of the month eight (8)
               years following the last Commencement Date to occur for floors
               one through four.  Landlord and Tenant shall confirm in writing
               the Commencement Date applicable to each floor of the Premises.
               Landlord and Tenant estimate that the Commencement Date shall be
               as follows for each of the floors:  (i) first floor:  February 1,
               2001; (ii) second floor:  February 15, 2001;  (iii) third floor:
               March 1, 2001; and (iv) fourth floor:  March 15, 2001.

          (2)  Conditions to Commencement of Initial Lease Term.  In order for
               ------------------------------------------------
               the Initial Lease Term to commence, the acquisition of Tenant by
               Stamps.com, Inc. must have occurred, and Tenant must have
               provided evidence of the same satisfactory to Landlord.

          (3)  Boundary Line Adjustment.  Landlord has caused a boundary line
               ------------------------
               adjustment involving the Land and the land on which Sterling
               Plaza I is located (the "Sterling Plaza I Property") to be
               recorded in the real property records of King County, Washington.
               Landlord hereby indemnifies Tenant with respect to any loss,
               cost, damage or expense incurred by Tenant in the event Landlord
               fails to obtain written approval from New York Life Insurance
               Company ("NYLIC"), Landlord's lender on Sterling Plaza I, of the
               boundary line adjustment necessary to legally separate the Land
               from the Sterling Plaza I Property which is encumbered by a deed
               of trust in favor of NYLIC.

          (4)  Option to Renew the Lease.  Provided Tenant is not then in
               -------------------------
               default under this Lease beyond any applicable notice an cure
               periods, either at the time notice of exercise is given or upon
               expiration of the initial term of this Lease, Tenant shall have
               the option to extend the term of this Lease for two (2) renewal
               terms of five (5) years (each, a "Renewal Term").  Except for the
               monthly rent described below and other economic terms, the terms,
               covenants, and conditions of this Lease shall remain unchanged
               during each Renewal Term (unless otherwise mutually agreed by
               Landlord and Tenant).  Tenant may exercise the option by giving
               written notice of exercise ("Tenant's Exercise Notice") to
               Landlord not earlier than fourteen (14) months but at least
               eleven (11) months prior to the expiration of the Initial Lease
               Term or the first Renewal Term, as applicable.  If Tenant's
               Exercise Notice is not timely given, the option to renew (and any
               subsequent option to renew) shall terminate.

          (5)  Determination of Market Rental Rate.  The rent to be paid during
               -----------------------------------
               each Renewal Term will be the then-market rental rate based upon
               rates prevailing at the time of commencement of the Renewal Term
               for comparable leases in comparable office buildings located in
               the vicinity of the I-90 corridor in the City of Bellevue,
               Washington.  Comparable leases shall include leases of a similar
               duration for tenants which are not directly or indirectly
               affiliated with their Landlord.  Within ninety (90) days after
               receipt of Tenant's Exercise Notice, Landlord will provide Tenant
               with a written proposal for rent during the upcoming Renewal
               Term.  Within sixty (60) days after Tenant's receipt of
               Landlord's written proposal, Tenant shall provide Landlord with a
               written response.  If, within sixty (60) days after Tenant's
               written response is received by Landlord, the parties are unable
               to reach an agreement as to the rental rate applicable during the
               Renewal Term, the then-market rental rate will be established as
               follows:  Landlord and Tenant shall each, by that date which is
               three (3)

                                      -3-
<PAGE>

               months prior to the commencement of the upcoming Renewal Term,
               retain an individual with substantial experience in the appraisal
               of commercial office property located in the Seattle-Bellevue
               metropolitan area and holding a designation of "MAI" or
               equivalent professional qualification (an "Appraiser"). The two
               Appraisers retained shall, within two (2) weeks of their
               appointment, appoint a third Appraiser. By that date which is two
               (2) months prior to the commencement of the upcoming Renewal
               Term, each Appraiser shall, through his or her independent
               research, determine the then-market rental rate (exclusive of
               triple-net additional rent) that he or she believes to be
               applicable to the Premises during the upcoming Renewal Term, and
               shall provide written notice of the same to Landlord, Tenant and
               the other Appraisers (the "Appraised Rent"). The Appraised Rents
               determined by the two Appraisers that are closest in dollar
               amount to one another shall be averaged, and the resulting number
               shall be the base rent for the upcoming Renewal Term. Landlord
               and Tenant shall each bear the cost of the Appraiser it appoints,
               and shall share equally the cost of the third Appraiser.
               Notwithstanding the foregoing, in no event shall the base rent
               payable during any Renewal Term be less than the base rent
               payable during the last month of Initial Lease Term or the first
               Renewal Term, as applicable.

     (f)  Rent.  The monthly rent for the Premises shall commence, on a floor-
          ----
          by-floor basis, on the Commencement Date.  The annual base rent for
          the Premises, on a per rentable square foot basis, is as follows:

                       1st year of Initial Lease Term:      $23.00
                       2nd year of Initial Lease Term:      $23.58
                       3rd year of Initial Lease Term:      $24.17
                       4th year of Initial Lease Term:      $24.78
                       5th year of Initial Lease Term:      $25.40
                       6th year of Initial Lease Term:      $26.04
                       7th year of Initial Lease Term:      $26.69
                       8th year of Initial Lease Term:      $27.36

          together with additional rent as provided in Section 8 of this Lease.
          The "first year" of the Initial Lease Term shall be the period from
          the first Commencement Date to the end of the twelfth (12th) month
          after the last Commencement Date. Such base rent shall be payable in
          equal monthly installments. Rent for any partial month at the
          beginning of the Initial Lease Term shall be prorated on the basis of
          the number of days elapsed. Landlord and Tenant shall confirm in
          writing the amount of base rent due based on the final calculations
          of, or any adjustments to, the floor area of the Premises. Rent is to
          be paid in advance on or before the first day of each month without
          offset or deduction at the offices of Landlord, Sterling Realty
          Organization Co., 600 - 106th Avenue NE, Suite 200, Bellevue,
          Washington 98004, or P.O. Box 91723, Bellevue, Washington 98009, or
          such other place designated by Landlord.

     (g)  Letters of Credit; Security Deposit.
          -----------------------------------

          (1)  Letter of Credit No. 1.  Tenant shall, on or before March 13,
               ----------------------
               2000, provide to Landlord an irrevocable letter of credit
               ("Letter of Credit No. 1") in the amount of $1,812,240.00
               (calculated by multiplying the 75,510 rentable square foot floor
               area of the Premises by $24.00), issued by a bank reasonably
               satisfactory to Landlord and in the form attached hereto as
               Exhibit F, as security for Tenant's performance of its
               ---------
               obligations under this Lease.   If Tenant fails to deliver Letter
               of Credit No. 1 to Landlord by March 13, 2000, then for each day
               thereafter until Letter of Credit No. 1 is delivered to Landlord,
               there will be a day-for-day delay in the target Commencement
               Dates set forth in Section 1(e) above.  The amount of Letter of
               Credit No. 1 shall be adjusted based on the final determination
               of floor area under Section 1(b) above, and Tenant shall increase
               the amount of Letter of Credit No. 1 when any floor area is,
               during the Initial Lease Term,

               added to the Premises in accordance with the provisions of this
               Lease. The amount of Letter of Credit No. 1 shall be reduced to
               zero in eight (8) annual reductions, each of 12.5% of the
               original amount of Letter of Credit No. 1, commencing on the last
               Commencement Date to occur (as set forth in Section 1(e)(1)
               above) and on each subsequent anniversary thereof. If Tenant is
               in default of its obligations under this Lease, Landlord may so
               certify to the issuer of Letter of Credit No. 1, and upon
               presentation, such issuer shall cause Letter of Credit No. 1 to
               be drawn down in its entirety and paid to Landlord. If the amount
               drawn down by Landlord under Letter of Credit No. 1 is in excess
               of the amount necessary to cure Tenant's default under this
               Lease, then Landlord shall hold the remainder of such funds as a
               security deposit (the "Security Deposit") for the account of
               Tenant. Landlord's obligations with respect to the Security
               Deposit are those of a debtor and not a trustee. Landlord may
               maintain such sums separate and apart from Landlord's general
               funds or may commingle them with Landlord's general or other
               funds. Landlord is not required to pay Tenant interest on such
               sums, or any portion thereof.

          (2)  Letter of Credit No. 2.  If, at any time after the first thirty
               ----------------------
               (30) months of the Initial Lease Term, Stamps.com, Inc. has a net
               operating loss, measured over the previous four calendar
               quarters, that is greater than one-half the amount of Stamps.com,
               Inc.'s then-current working capital, all as determined in
               accordance with generally accepted accounting principles, Tenant
               shall provide to Landlord an additional irrevocable letter of
               credit issued by a bank reasonably satisfactory to Landlord and
               in the form attached hereto as Exhibit F in an amount equal to
                                              ---------
               the then-rentable square foot floor area of the Premises
               multiplied by $10.00 ("Letter of Credit No. 2").  Letter of
               Credit No. 2 shall remain posted with Landlord for so long as
               Stamps.com, Inc.'s financial condition remains as stated in the
               preceding sentence.  If Tenant is in default of its obligations
               under this Lease, Landlord may so certify to the issuer of Letter
               of Credit No. 2, and upon presentation, such issuer shall cause
               Letter of Credit of Credit No. 2 to be drawn down in its entirety
               and paid to Landlord.  If the amount drawn down by Landlord under
               Letter of Credit No. 2 is in excess of the amount necessary to
               cure Tenant's default under this Lease, then Landlord shall hold
               the remainder of such funds as a Security Deposit for the account
               of Tenant.

     (h)  Financial Statements.  Promptly following the end of each fiscal
          --------------------
          quarter, Tenant shall provide Landlord with copies of financial
          statements for Tenant and Stamps.com, Inc. for the previous fiscal
          quarter, certified by Tenant's chief financial officer and the chief
          financial officer of Stamps.com, Inc., respectively, to be true,
          accurate and complete.  Financial statements shall be required for
          only Stamps.com, Inc. if Tenant and Stamps.com, Inc. report on a
          consolidated basis.  Landlord shall keep all such financial
          information confidential, provided that Landlord may disclose such
          information, on a confidential basis, to Landlord's mortgagee or
          prospective purchasers of the Land and the Building.

     (i)  Guaranty of Lease.  Stamps.com, Inc., Tenant's parent company
          -----------------
          following the acquisition that is a condition to the commencement of
          this Lease, shall guaranty the payment and performance of all of
          Tenant's obligations under this Lease, as evidenced by its execution
          of the Guaranty of Lease, the form of which is attached hereto as
          Exhibit G.
          ---------

     (j)  Permitted Uses.  The Premises shall be used only for general office
          --------------
          purposes and uses ancillary thereto (including without limitation a
          computer server room, auditorium, conference room, exercise facility
          and cafeteria and dining facility, but only so long as such uses are
          ancillary to the general office use of the Premises, used only by
          employees of Tenant (unless otherwise agreed in writing by Landlord),
          and such ancillary uses do not require any additional parking under
          City of Bellevue zoning ordinances) and for no other purpose or use
          without the written consent of Landlord.

2.   Premises.  Landlord does hereby lease to Tenant, and Tenant does hereby
     lease from Landlord, upon the terms and conditions herein set forth, the
     Premises described in Section 1(a) hereof.

3.   Term.  The Lease term shall be for the period stated in Section 1(e)
     hereof.  The Lease term shall commence on the Commencement Date specified
     in Section 1(e).  Neither Landlord nor any agent or employee of Landlord
     shall be liable for any damage or loss due to Landlord's inability or
     failure to deliver possession of the Premises to Tenant as provided herein.

4.   Rent.  Tenant shall pay Landlord the monthly rent stated in Section 1(f)
     hereof without demand, deduction or offset (except as otherwise expressly
     provided in this Lease), payable in lawful money of the United States in
     advance on or before the day specified in Section 1(f) to Landlord at the
     offices of Landlord or its building manager at the place specified in
     Section 1(f), or to such other party or at such other place as Landlord may
     hereafter from time to time designate in writing.  Rent for any partial
     month at the beginning or end of the Lease term shall be prorated.
     Notwithstanding anything in Section 8 hereof, the rent payable by Tenant
     shall in no event be less than the rent specified in Section 1(f) of this
     Lease.

     (a)  Late Fees On Overdue Rent.  With respect to the first two (2) times
          -------------------------
          during any calendar year of the Lease term that Tenant fails to pay
          any rent, additional rent or other sums payable by Tenant to Landlord
          hereunder in a timely manner, Landlord shall provide written notice to
          Tenant so stating (each, a "Late Notice").  If such payment is not
          received within three (3) days following receipt of the Late Notice,
          then such rent, additional rent or other sums payable by Tenant to
          Landlord shall bear interest at a rate equal to three percent (3%) per
          annum, compounded monthly, above the prime lending rate as publicly
          announced from time to time by Bank of America, calculated from the
          date of delinquency to the date of payment (the "Default Rate").  If,
          during any calendar year of the Lease term Tenant has received two (2)
          Late Notices and Tenant fails to pay to Landlord any rent, additional
          rent or other sums due hereunder when due, then such amounts shall
          bear interest at the Default Rate from the date of delinquency to the
          date of payment.

     (b)  Collection Fee on Overdue Rent.  With respect to the first two (2)
          ------------------------------
          times during any calendar year of the Lease term that Tenant fails to
          pay its rent in a timely manner, Landlord shall provide a Late Notice
          to Tenant.  If such payment is not received within three (3) days
          following receipt of the Late Notice, then such rent, additional rent
          or other sums payable by Tenant to Landlord shall also be subject to a
          collection fee equal to three percent (3%) of the amount due.  If,
          during any calendar year of the Lease term Tenant has received two (2)
          Late Notices and Tenant fails to pay to Landlord any rent, additional
          rent or other sums due hereunder when due, then such amounts shall be
          subject to a collection fee equal to three percent (3%) of the amount
          due.

     of any first mortgage or deed of trust at such place as such holder shall
     specify to Tenant in writing; or at such other facsimile number or address
     as may from time to time be designated by each party in writing.  Notices
     will be deemed to have been given on the date sent by facsimile with

6.   Uses.  The Premises are to be used only for the uses specified in Section
     1(j) hereof (the "Permitted Uses") and for no other business or purpose

     apparatus, machinery or device in or about the Premises which will cause
     any substantial noise or vibration or any increase in the normal use of
     electric power.  If any of Tenant's office equipment should disturb the
     quiet enjoyment of any other tenant in the Building, then Tenant shall
     provide adequate insulation, or take other such action as may be necessary
     to eliminate the disturbance.  Tenant shall comply with all laws and

     Premises or the Building, and for the preservation of good order therein,
     including but not limited to any Rules and Regulations currently in effect,
     which are attached to this Lease as Exhibit H.  Such rules and regulations
                                         ---------
     shall not be inconsistent with the terms of this Lease and shall be
     enforced against all tenants of the Building in a non-discriminatory
     manner.

7.   Services and Utilities.  Landlord shall furnish the Premises with
     electricity for lighting and operation of customary office machines, water,
     and elevator service, and, during Normal Business Hours, lighting, heat and
     normal air conditioning.  "Normal Business Hours" are defined as 7:00 a.m.

          injury or damage to property caused by or resulting from any

          outside of Landlord's reasonable control, except if such interruption
          or failure continues for forty-eight (48) hours or more, in which case
          rent shall be abated for that time after forty-eight (48) hours until
          such interruption ceases.  In the event of such variation,
          interruption or failure, however, Landlord shall use reasonable
          diligence to restore such service.  Except as provided above, no
          temporary interruption or failure of such service incident to the
          making of repairs, alterations or improvements or due to accident or
          strike, or conditions or events beyond Landlord's reasonable control
          shall be deemed an eviction of Tenant or relieve Tenant from any of
          Tenant's obligations hereunder.

               placed in service). Currently there are three buildings located
               in the Project, the Building, Sterling Plaza I (which has 127,401
               rentable square feet) and the Factoria Cinemas (which has 47,621
               rentable square feet). All Operating Costs associated with the
               operation of the parking areas, including any parking control
               mechanism or valet parking service, will be pro rated among users
               of the Project and the users of the 12600 Building (which has
               52,227 rentable square feet).

          (3)  "Estimated Operating Costs" means Landlord's estimate of
                -------------------------
               Operating Costs for the following Lease Year to be given by
               Landlord to Tenant pursuant to Section 8(b)(1).

     (b)  Additional Rent.  Tenant shall pay to Landlord as rent, in addition to
          ---------------
          the rent provided in Section 1(f) above, all Operating Costs allocable
          to the Premises and any and all other sums expressly provided for
          hereunder.

          (1)  Rent Adjustment for Estimated Operating Costs.  Landlord shall,
               ---------------------------------------------
               prior to the first Commencement Date and within 90 days after the
               commencement of each Lease Year thereafter, furnish to Tenant a
               written statement setting forth (A) Tenant's proportionate share
               of Estimated Operating Costs for such Lease Year, and (B) the
               amount of Additional Rent payable monthly during such Lease Year,
               which will equal one-twelfth (1/12) of the amount.  If such
               Estimated Operating Costs are furnished after the commencement of
               the Lease Year, Tenant shall also make a retroactive lump-sum
               payment equal to the amount of such excess multiplied by the
               number of months during the Lease Year for which no such
               adjustment was paid.

          (2)  Actual Operating Costs.  Within ninety (90) days after the close
               ----------------------
               of each Lease Year during the term hereof, Landlord shall deliver
               to Tenant a written statement setting forth the actual Operating
               Costs during the preceding Lease Year.  If such costs for any
               Lease Year exceed the Estimated Operating Costs paid by Tenant to
               Landlord pursuant to Section 8(b)(1) for such Lease Year, Tenant
               shall pay the amount of such excess to Landlord as additional
               rent within thirty (30) days after receipt of such statement by
               Tenant.  If such statement shows such costs to be less than the
               amount paid by Tenant to Landlord pursuant to Section 8(b)(1),
               then the amount of such overpayment shall be credited toward the
               next monthly rent payable by Tenant or, if this Lease has
               terminated, shall be paid to Tenant within thirty (30) days.

          (3)  Determinations.  The determination of Operating Costs and
               --------------
               Estimated Operating Costs shall be made by Landlord in its
               reasonable business judgment.  If Tenant notifies Landlord in
               writing within three (3) years after the receipt by Tenant of
               Landlord's statement setting forth the preceding years' Operating
               Costs, then Tenant may review or audit Landlord's books and
               records pertaining to Operating Costs.  In the event that any
               such audit, conducted in accordance with generally accepted
               accounting principles, reveals a discrepancy of three percent
               (3%) or more between Landlord's statement of the actual Operating
               Costs for a Lease Year and the amount of such Operating Costs
               determined by such audit, then if the Operating Costs were
               overstated Landlord shall reimburse to Tenant the excess amount
               paid by Tenant and Landlord shall pay for the

                                      -9-
<PAGE>

               reasonable cost of such audit; but if the Operating Costs were
               understated then Tenant shall pay to Landlord the amount of such
               deficiency and Tenant shall pay for the cost of such audit.

               Rent due pursuant to this section shall be 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 rent
               hereunder.

          (4)  Extra Services Requested by Tenant.  If Tenant requests Landlord
               ----------------------------------
               to provide extra services not included in Operating Costs, and
               Landlord agrees to do so, such services will, during the Initial
               Term of this Lease, be charged at a rate of Fifty Dollars
               ($50.00) per hour for Landlord's agent to perform or supervise
               such services for the repair, maintenance and operation of the
               Premises as Tenant may request.  Landlord will separately invoice
               Tenant for the cost of such services, and the amount due shall be
               Additional Rent payable by Tenant hereunder.

          (5)  End of Term.  If this Lease terminates on a day other than the
               -----------
               last day of a Lease Year, the amount of any adjustment between
               Estimated Operating Costs and Actual Operating Costs with respect
               to the Lease Year in which such termination occurs will be
               prorated on the basis which the number of days from the
               commencement of such Lease Year to and including such termination
               date bears to 365, and any amount payable by Landlord to Tenant
               or Tenant to Landlord with respect to such adjustment is payable
               within thirty (30) days after delivery of the Statement of
               Operating Costs with respect to such Lease Year.

9.   Property Taxes.   "Property Taxes" means all real property taxes and
     assessments and personal property taxes, charges and assessments levied
     with respect to the Land, the Building, and any improvements, fixtures and
     equipment, and all other property of Landlord, real or personal, located in
     or on the Building and used in connection with the operation of the
     Building.  In addition to the foregoing, Property Taxes shall include a pro
     rata portion of all real property taxes and assessments for the driveway,
     parking, and related landscaped areas of the Project (the "Parking Lot
     Taxes").  The portion of the Parking Lot Taxes allocated to the Tenant
     shall be equal to the percentage of rentable space occupied by the Tenant
     compared to the total amount of rentable square feet contained in the
     Project (including the Factoria Cinemas).  Tenant's share of Parking Lot
     Taxes shall be computed by multiplying the total Parking Lot Taxes by a
     fraction, the numerator of which is 75,510 (i.e. the rentable area of the
     Premises), and the denominator of which is the sum of the rentable areas
     expressed in square feet of all buildings now or hereafter located in the
     Project (pro rated as to the fraction of any year from the time any such
     new building is completed and placed in service).  Currently there are
     three buildings located in the Project, the Building (which has 92,866
     rentable square feet, Sterling Plaza I (which has 127,401 rentable square
     feet) and the Factoria Cinemas (which has 47,621 rentable square feet), for
     a total of 267,888 rentable square feet.

10.  Taxes on Rents and Personal Property.  If any governmental authority shall
     in any manner levy a tax on rents payable under this Lease or rents
     accruing from Tenant's use of property, or such a tax in any form against
     Landlord measured by income derived from the leasing or rental of the
     Building, such tax shall be paid by Tenant either directly or through
     Landlord; provided, however, that Tenant shall not be liable to pay any
     state or federal income tax imposed on Landlord.

     Tenant shall pay prior to delinquency all personal property taxes with
     respect to all property of Tenant located on the Premises or the Building
     and shall provide promptly upon request of Landlord written proof of such
     payment.

11.  Acceptance of Premises.  Landlord shall deliver the Premises to Tenant in a
     clean and orderly condition and in accordance with the provisions of
     Section 1(e) above.

                                      -10-
<PAGE>

12.  Improvements.  Subject to Section 21 of this Lease, upon the expiration or
     sooner termination of this Lease, all improvements and additions to the
     Premises made by Tenant shall become the property of Landlord.

13.  Alterations and Care of Premises.  Tenant shall take good care of the
     Premises and shall promptly make all necessary repairs and maintenance,
     except those to be made by Landlord as provided herein.  Additionally, if
     Tenant elects to upgrade the generator that Landlord would otherwise have
     provided to operate the life safety systems of the Building, Tenant shall,
     during the term of this Lease, maintain such generator in accordance with
     all manufacturer's instructions relating thereto.

     (a)  Except as expressly permitted by the terms of this paragraph, Tenant
          shall not make any alterations, additions or improvements in or to the
          Premises, or make changes to locks on doors, or add, disturb or in any
          way change any floor covering, wall covering, fixtures, plumbing or
          wiring, without first obtaining the written consent of Landlord, which
          consent shall not be unreasonably withheld or delayed.  Landlord may,
          in determining whether to grant or withhold its consent to a
          particular alteration, addition or improvement, consider the
          likelihood that the particular alteration, addition or improvement
          will be usable by a subsequent tenant of the Premises.
          Notwithstanding the foregoing, Landlord's consent shall not be
          required for changes that cost Fifty Thousand Dollars ($50,000) or
          less and do not affect Building systems.  If Landlord withholds its
          consent to a particular alteration, addition or improvement based on
          the unlikelihood that a subsequent tenant would find that alteration,
          addition or improvement usable, then Tenant may proceed to make the
          particular alteration, addition or improvement, but shall remove it
          from the Premises prior to the expiration or earlier termination of
          this Lease.  Within thirty (30) days following the completion of any
          alterations or improvements, Tenant shall provide Landlord with "as-
          built" plans showing the alterations or improvements made to the
          Premises.

     (b)  If Landlord's consent is required, then prior to Tenant commencing
          work on any alteration, addition or improvement to the Premises,
          Tenant shall submit to Landlord two (2) copies, and, at the request of
          Landlord, shall submit to any mortgagee holding a mortgage or deed of
          trust encumbrance on the Land one (1) copy, of full and complete plans
          and specifications detailing the design and plan of improvements for
          any such alteration, addition or improvement.

          Landlord does not and will not make any covenant or warranty, express
          or implied, that any such plans or specifications submitted by Tenant
          are accurate, complete or in any way suited for their intended
          purpose.  Landlord shall either approve or disapprove plans within
          five (5) business days and, if approved, return a signed, approved
          copy to Tenant.  Landlord will not unreasonably withhold or delay its
          approval.  In the event that the plans are not approved by Landlord,
          Landlord shall inform Tenant of the reasons for its disapproval and
          Tenant shall have twenty (20) days in which to submit revised plans to
          Landlord for approval.  Tenant shall not unreasonably refuse to
          satisfy any objections made by Landlord to the plans and
          specifications.  Any objections Tenant has to Landlord's objection
          shall be submitted to Landlord in writing within the twenty (20) day
          period.  Landlord shall respond to such revised plans within five (5)
          business days after their submittal by Tenant.  A failure of one party
          to give any notice to the other party within the period provided for
          doing so shall be deemed to constitute approval of the plans and
          specifications or the objections thereto, as appropriate. Within
          thirty (30) days following the completion of any alterations or
          improvements, Tenant shall provide Landlord with "as-built" plans
          showing the alterations or improvements made to the Premises.

     (c)  All such work so done by Tenant shall be done in accordance with all
          laws, ordinances, and rules and regulations of any federal, state,
          county, municipal or other public authority and/or Board of Fire
          Underwriters.  Tenant expressly covenants and agrees that no liens of
          mechanics, materialmen, laborers, architects, artisans, contractors or
          subcontractors engaged by or through Tenant, or any other lien of any
          kind whatsoever arising by or through Tenant, shall be created against
          or imposed upon the Premises, the Land or the Building, and that in
          the event any such

                                      -11-
<PAGE>

          claims or liens of any kind whatsoever shall be asserted or filed by
          any persons, firms or corporations performing labor or furnishing
          material in connection with such work, Tenant shall pay off or cause
          the same to be discharged of record within five (5) days of
          notification thereof. Except as provided in Section 21 below, all
          alterations, improvements, or changes made by Tenant to the Premises
          shall be the property of Landlord and shall remain upon and be
          surrendered with the Premises upon the termination of this Lease;
          provided, however, that Tenant shall remove any alteration, addition
          or improvement made to the Premises by Tenant subsequent to the
          completion of the initial tenant improvements to be made pursuant to
          Exhibit E and to which Landlord withheld its consent under the terms
          ---------
          of Section 13(b) above.  Tenant will remove any such alterations,
          additions or improvements made by Tenant prior to Tenant surrendering
          possession of the Premises to Landlord, and repair any damage caused
          to the Premises thereby, all at the sole cost and expense of Tenant.

          After the beginning of each Lease Year during the term of this Lease
          or any Renewal Term, Landlord may deliver a certificate to Tenant
          requesting that Tenant provide Landlord with an itemized list of all
          alterations, improvements or changes that Tenant has made to the
          Premises during the previous Lease Year.  Tenant shall complete the
          certificate and return the same to Landlord within thirty (30) days
          following the date on which it was received.  In the event no
          alterations or improvements were made during the previous Lease Year,
          Tenant shall so indicate on the certificate provided.

          All damage or injury done to the Building or the Premises or any
          appurtenances to either by Tenant, or by Tenant's agents, invitees,
          licensees, or employees, including the cracking or breaking of glass
          of any windows and doors, shall be paid for by Tenant.

     (d)  Tenant shall not put curtains, draperies or other hangings on or
          beside the windows in the Premises or place any furniture on the
          patios or common areas without first obtaining Landlord's consent.
          All normal repairs necessary to maintain the Premises in a tenantable
          condition and consistent with the standards for a Class A office
          building in the Bellevue metropolitan area shall be done by or under
          the direction of Landlord, acting reasonably and in good faith.
          Tenant shall promptly notify Landlord of any damage to the Premises
          requiring repair, and if such repair is Landlord's obligation under
          the terms of this Lease, Landlord shall make such repair within thirty
          (30) days thereafter.  If Landlord fails to respond to Tenant's notice
          within the 30-day period provided for doing so, then Tenant may cause
          the repairs to be accomplished.  Landlord shall reimburse Tenant for
          all reasonable costs and expenses incurred by Tenant in making the
          repairs, and such reimbursement shall be made within thirty (30) days
          of Landlord's receipt of an invoice for the amount of such costs and
          expenses.

     (e)  Landlord shall be responsible for maintaining and repairing the
          structural components of the Building at Landlord's sole cost.  If
          Tenant believes that there is a problem or defect in the structural
          elements of the Building, including problems or defects in the
          foundation, exterior walls, floors or the roof system, and also
          including but not limited to safety aspects of the Building (as
          determined under applicable building codes as in effect on the date
          hereof), Tenant shall give Landlord notice of any such defect.  Tenant
          and Landlord shall cooperate to determine promptly whether any such
          defect exists and to identify any damage to the Building resulting
          from such defect.  Landlord shall repair any such defect and resulting
          damage.  If Landlord fails to make any such repairs which can
          reasonably be completed within fifteen (15) days, within thirty (30)
          days after such determination, or fails to commence within thirty (30)
          days after such determination and diligently proceed to complete any
          such repairs which cannot reasonably be completed in fifteen (15)
          days, Tenant shall have the right, but not the obligation, to cause
          such repairs to be accomplished. Landlord shall reimburse Tenant for
          all reasonable costs and expenses incurred by Tenant in making the
          repairs, and such reimbursement shall be made within thirty (30) days
          of Landlord's receipt of an invoice for the amount of such costs and
          expenses.  Landlord shall also maintain all common areas of the
          Building (including the Building exterior, landscaping

                                      -12-
<PAGE>

          and parking areas) in first-class condition and repair and consistent
          with the standards for a Class A office building in the Bellevue
          metropolitan area, at Landlord's cost but subject to reimbursement as
          set forth in Section 8 above.

     (f)  Tenant shall, at the expiration or sooner termination of this Lease,
          surrender and deliver the Premises to Landlord in as good or better
          condition as when received by Tenant from Landlord or as thereafter
          improved, reasonable use and wear and damage by fire or other insured
          casualty excepted.

14.  Liens and Insolvency.  Tenant shall keep the Premises and the Building free
     from any liens arising out of any work performed, materials ordered or
     obligations incurred by Tenant.  If Tenant becomes insolvent, voluntarily
     or involuntarily bankrupt, or if a receiver, assignee or other liquidating
     officer is appointed for the business of Tenant, then Tenant shall be
     deemed to be in default under the terms of this Lease and Landlord may, in
     addition to any other remedy provided in this Lease, terminate Tenant's
     right of possession under this Lease at Landlord's option and in no event
     shall the Lease or any rights or privileges hereunder be an asset of Tenant
     under any bankruptcy, insolvency or reorganization proceedings.

15.  Access.  Tenant shall permit Landlord and its agents (including, but not
     limited to any mortgagee holding a mortgage or deed of trust which is an
     encumbrance against the Land) to enter into and upon the Premises but,
     except in an emergency, only on advance reasonable notice and at reasonable
     times for the purpose of inspecting the same or for the purpose of
     repairing, altering or improving the Premises or the Building, with minimum
     interference to Tenant.  Nothing contained in this Section 15 shall be
     deemed to impose any obligation upon Landlord not expressly stated herein
     or elsewhere in this Lease.  Landlord shall, on the same basis, have the
     right to enter the Premises for the purpose of showing the Premises to
     prospective tenants within 270 days prior to the expiration or sooner
     termination of the Lease term.

16.  Damage or Destruction. If the Building or the Premises are destroyed or
     damaged by fire or other casualty insured against under Landlord's fire and
     extended coverage insurance policy to the extent that more than fifty
     percent (50%) of either is rendered untenantable, or if the Building or the
     Premises are destroyed or materially damaged by any other casualty other
     than those covered by such insurance policy, notwithstanding that the
     Premises may be unaffected directly by such destruction or damage, Landlord
     may, at its election, terminate this Lease by notice in writing to Tenant
     within sixty (60) days after such destruction or damage. Such notice will
     be effective thirty (30) days after receipt thereof by Tenant. Landlord
     shall not be required to repair or restore fixtures, improvements, or other
     property of Tenant. If Landlord elects to restore the Premises, then
     Landlord shall so notify Tenant within sixty (60) days after such
     destruction or damage, and shall begin the restoration work within thirty
     (30) days of such date, in which event this Lease will continue in full
     force and effect. If Landlord fails to notify Tenant of its election within
     sixty (60) days after such destruction or damage, then Tenant may terminate
     this Lease immediately upon written notice to Landlord. Tenant may also
     terminate this Lease if the damage or destruction is reasonably anticipated
     to render the Premises untenantable for one hundred eighty (180) days or
     more, or if damage or destruction occurs within the last twelve (12) months
     of the Lease term. Rent and all other amounts owing hereunder shall abate
     for as long as and to the extent the Premises are rendered untenantable as
     a result of any such destruction or damage, unless such damage or
     destruction is due directly or indirectly to the intentional misconduct of
     Tenant or its officers, contractors, licensees, agents, servants,
     employees, guests, invitees or visitors, in which case there will be an
     abatement of rent only to the extent Landlord collects rental loss
     insurance proceeds.

     (a)  Business Interruption.  Other than as provided in this Section 16
          ---------------------
          above, no damages, compensation, or claim shall be payable by Landlord
          to Tenant for inconvenience, loss of business, or annoyance arising
          from any repair or restoration of any portion of the Premises or of
          the Building as a result of fire or other casualty.  Landlord shall
          use its best efforts to effect such repairs promptly.

     (b)  Tenant Improvements and Personal Property.  Landlord will not carry
          -----------------------------------------
          insurance of any kind on Tenant's furniture or furnishings or on any
          other personal property fixtures, equipment, improvements, or
          appurtenances owned or installed by Tenant, and Landlord shall not be
          obligated to repair any damage thereto or replace the same.

                                      -13-
<PAGE>

17.  Indemnification, Insurance and Waiver of Subrogation.

     (a)  Indemnification.  It is understood and agreed that Landlord shall not
          ---------------
          be liable for injury to any person, or for the loss of or damage to
          any property (including property of Tenant) occurring in or about the
          Premises from any cause whatsoever, except for that caused by
          Landlord's negligence, willful misconduct or breach of its obligations
          under this Lease.  Tenant hereby indemnifies and holds Landlord
          harmless from and against and agrees to defend Landlord against any
          and all claims, charges, liabilities, obligations, penalties, causes
          of action; liens, damages, costs and expenses (including attorneys'
          fees) arising, claimed, charged or incurred against or by Landlord
          from any matter or thing arising from Tenant's use of the Premises,
          the conduct of its business or from any activity, work or other thing
          done, permitted or suffered by Tenant in or about the Premises or
          Common Areas, or in connection with the installation, operation,
          maintenance, existence or removal of a satellite dish or antenna and
          related facilities, if any, installed by Tenant on the roof of the
          Building, whether arising from any breach or default in the
          performance of any obligation on Tenant's part or to be performed
          under the terms of this Lease, or arising from any act or negligence
          of Tenant, or any officers, contractor, agent, employee, guest,
          licensee, or invitee of tenant, and from all costs, attorneys' fees,
          and liabilities incurred in or about the defense of any such claim
          (including appeals) or any action or proceeding brought thereon and in
          the event that any action or proceeding is brought against Landlord by
          reason of such claim, except to the extent any of the foregoing is
          caused by the negligence or willful misconduct of Landlord or
          Landlord's breach of its obligations under this Lease.  Tenant, upon
          notice from Landlord, shall defend the same at Tenant's expense by
          counsel reasonably satisfactory to Landlord.  The indemnification
          provided for in this paragraph shall survive any termination or
          expiration of this Lease.  Landlord and its agents shall not be liable
          for any loss or damage to persons or property resulting from fire,
          explosion, falling plaster, steam, gas, electricity, water or rain
          which may leak from any part of the Premises or from pipes, appliances
          or plumbing works therein or from the roof, street or subsurface or
          from any other place resulting from dampness or any other cause
          whatsoever, unless caused by or due to the negligence or willful
          misconduct of Landlord, its agents or employees or Landlord's breach
          of its obligations under this Lease.  Landlord and its agents shall
          not be liable for interference with the light or air to the Premises
          or for any latent defect on the Premises.  Tenant shall give prompt
          notice to Landlord in case of casualty or accidents on or about the
          Premises.  Landlord shall indemnify, defend and hold Tenant harmless
          from all loss, cost, expense and liability arising as a result of
          Landlord's negligence or breach of its obligations under this Lease.

     (b)  Insurance.
          ---------

          (1)  Tenant's Insurance.
               ------------------

               (A)  Liability Coverage.  During the entire Lease Term and at any
                    ------------------
                    time prior to the Lease Term commencing with the day on
                    which possession of the Premises is delivered to Tenant for
                    any reason, Tenant shall, at its own expense, maintain
                    commercial general liability insurance with a reputable
                    insurance company or companies with minimum amounts of Two
                    Million Dollars ($2,000,000) combined single limit per
                    occurrence and in the aggregate for personal injuries and
                    property damage on or about the Premises, or in connection
                    with the installation, operation, maintenance, existence or
                    removal of a satellite dish or antenna and related
                    facilities, if any, installed by Tenant on the roof of the
                    Building, to indemnify both Landlord and Tenant against any
                    such claims, demands, losses, damages, liabilities and
                    expenses.  Landlord and the management company, if any,
                    employed by Landlord with respect to the Building shall be
                    named as additional insureds and shall be furnished with a
                    certificate of insurance which shall bear an endorsement
                    that the same shall not

                                      -14-
<PAGE>

                    be canceled except upon not less than thirty (30) days'
                    prior written notice to Landlord.

               (B)  Property Coverage.  Tenant shall, at its own expense,
                    -----------------
                    maintain during the Lease Term and at any time prior to the
                    Lease Term commencing with the date on which possession of
                    the Premises is delivered to Tenant for any reason,
                    insurance covering its furniture, fixtures, equipment, all
                    leasehold improvements and inventory in an amount equal not
                    less than 100% of the full replacement value thereof as
                    provided by basic form coverage with a special form
                    endorsement.

               (C)  Business Income and Extra Expense Coverage.  Tenant shall
                    ------------------------------------------
                    maintain business income and extra expense coverage at 100%
                    of Tenant's gross revenue for a period of twelve (12)
                    months.

               (D)  Commercial Auto Liability Coverage.  Tenant shall maintain
                    ----------------------------------
                    commercial auto liability insurance with a combined limit of
                    not less than One Million Dollars ($1,000,000) for bodily
                    injury and property damage for each accident.  Such
                    insurance shall cover liability relating to any auto
                    (including owned, hired and non-owned autos).

          (2)  Landlord's Insurance.  Landlord shall procure and maintain
               --------------------
               physical damage insurance covering all real and personal
               property, excluding property paid for by tenants and not
               reimbursed by Landlord or paid for by Landlord for which tenants
               have reimbursed Landlord, located on or in, or constituting a
               part of, the Building in an amount equal to one hundred percent
               (100%) of the replacement value of all such property.  Such
               insurance shall afford coverage for damages resulting from (i)
               perils covered by what is commonly referred to as special form
               insurance (including water damage, but excluding flood), and (ii)
               boilers and machinery coverage as appropriate for apparatus
               located in the Building, and shall include Business Income and
               Extra Expense coverage in such amounts as Landlord reasonably
               deems appropriate.  Landlord shall also procure and maintain
               commercial general liability insurance with broad form general
               liability endorsement covering all claims with respect to
               injuries or damages to persons or property sustained in, on or
               about the Building and the appurtenances thereto, including the
               sidewalks and alleyways adjacent thereto, with limits of
               liability no less than Two Million Dollars ($2,000,000) combined
               single limit per occurrence and in the aggregate.  Such limits
               may be achieved through the use of umbrella liability insurance
               otherwise meeting the requirements of this Section.

     (c)  Increase in Insurance Premium.  Tenant shall not keep, use, sell or
          ------------------------------
          offer for sale in or upon the Premises any article which may be
          prohibited by the form of property insurance policy required to be
          carried under this Lease.  Tenant shall pay any increase in premiums
          for property (including special form coverage) insurance that may be
          charged during the term of this Lease on the amount of such insurance
          which may be carried by Landlord on the Premises, the Building or the
          Property of which the Premises are a part, resulting from Tenant's
          particular use of the Premises, whether or not Landlord has consented
          thereto.  In such event, Tenant shall also pay any additional premiums
          on the insurance policy that Landlord may carry for its protection
          against the loss of business income through property damage.  In
          determining whether increased premiums are the result of Tenant's
          particular use of the Premises, a schedule, issued by the organization
          setting the insurance rate on the Premises, showing the various
          components of such rate, shall be conclusive evidence of the several
          items and charges which make up the property insurance rate on the
          Premises.  Landlord shall deliver bills for such additional premiums
          to Tenant at such times as Landlord may elect, and Tenant shall
          immediately reimburse Landlord therefor.

                                      -15-
<PAGE>

     (d)  Waiver of Subrogation.  Landlord and Tenant hereby mutually release
          ---------------------
          each other from liability and waive all rights of recovery against
          each other for any loss in or about the Premises, from perils insured
          against under their respective property insurance policies, including
          any special form endorsements thereof, whether due to negligence or
          any other cause.  This paragraph shall, however, be inapplicable if it
          would have the effect, but only to the extent it would have the
          effect, of invalidating any insurance coverage of Landlord or Tenant.
          Each of Landlord and Tenant shall, at the request of the other,
          execute and deliver to the other a Waiver of Subrogation in the form
          and content as required by such party's insurance carrier.

     (e)  Companies.  Insurance required hereunder shall be issued by companies
          ---------
          rated A-VII or better in "Bests" Insurance Guide, or such other
          companies approved by Landlord.

     (f)  Certificate of Insurance.  A certificate issued by the insurance
          ------------------------
          carrier for each policy of insurance required to be maintained by
          Tenant under the provisions of this Lease shall be delivered to
          Landlord upon or before the delivery of the Premises to Tenant for any
          purpose, and thereafter within thirty (30) days prior to the
          expiration of the term of each such policy.  Each certificate of
          insurance and each policy of insurance required to be maintained by
          Tenant hereunder shall expressly evidence insurance coverage as
          required by this Lease.  All such policies shall be written as primary
          policies not contributing with and not in excess of coverage which
          Landlord may carry.

18.  Assignment and Subletting.

     (a)  Assignment, Mortgage or Encumbrance.  Except as provided below, Tenant
          -----------------------------------
          shall not voluntarily or by operation of law assign, mortgage or
          otherwise encumber all or any part of Tenant's interest in this Lease
          or in the Premises without obtaining the prior written consent of
          Landlord in each instance, and any attempt to do so without first
          obtaining such consent shall be voidable at the option of Landlord.
          Landlord shall not, however, unreasonably withhold or delay such
          consent, but such consent shall require that such assignee, mortgagee
          or encumbrancer agree to be bound by all of the terms and conditions
          of this Lease.  Notwithstanding any of the foregoing, without the
          consent of Landlord, Tenant may voluntarily or by operation of law
          assign and delegate this Lease to the surviving corporation upon any
          reorganization, merger, consolidation or acquisition of Tenant, and
          Tenant may assign, sublet and delegate this Lease for all or any
          portion of the Premises to its parent company, any wholly-owned
          subsidiary or any affiliate, provided that both Tenant and any such
          assignee shall both be bound by all of the terms and conditions of
          this Lease.  Without in any way limiting the foregoing, Landlord
          hereby specifically approves the acquisition of Tenant, whether
          through merger or otherwise, by Stamps.com, Inc.

     (b)  Sublease.  Tenant shall not sublease the Premises without obtaining
          --------
          the prior written consent of Landlord, which consent of Landlord shall
          not be unreasonably withheld or delayed, and which consent shall
          require that such sublessee agree to be bound by all of the terms and
          conditions of this Lease applicable to such subleased space.

     (c)  Requirements for Request for Assignment or Sublease; Standards for
          ------------------------------------------------------------------
          Consent.  In the event Tenant desires to assign this Lease or sublet
          -------
          the Premises or any part hereof, Tenant shall give Landlord written
          notice at least thirty (30) days in advance of the date on which
          Tenant desires to make such assignment or sublease, which notice shall
          specify: (a) the name, address and business of the proposed assignee
          or sublessee, (b) the amount and location of the space affected, (c)
          the proposed effective date and duration of the sublease or
          assignment, and (d) current financial statements of the proposed
          assignee or sublessee.  Each request for an assignment or subletting
          must be accompanied by a Processing Fee, equal to no less than Five
          Hundred Dollars ($500.00) plus reasonable legal fees, in order to
          reimburse Landlord for expenses incurred in connection with such
          request.

                                      -16-
<PAGE>

          In reviewing any request for an assignment of Tenant's interest under
          this Lease or a sublease of the Premises or a portion thereof,
          Landlord may take into consideration the credit-worthiness of the
          proposed assignee or sublessee, the purpose for which the proposed
          assignee or sublessee will use the Premises, and whether the proposed
          assignee or sublessee is anticipated to require parking in excess of
          the parking allocated to Tenant under this Lease. Use and occupancy of
          the Premises or any portion thereof by an assignee or sublessee will
          be consistent with operation and maintenance of a First Class office
          building and will not be in conflict with any other Lease in the
          Building. Consent to one assignment, subleasing or other transfer
          shall not be deemed to constitute consent to any subsequent
          assignment, subleasing or other transfer of Tenant's interest in this
          Lease. Except as expressly provided herein, no such assignment or
          sublease shall relieve Tenant of any liability under this Lease
          regardless of whether such liability arises by or through Tenant.
          Assignment or subletting shall not operate as a waiver of the
          necessity for a written consent to any subsequent assignment or
          sublease, and the terms of such consent shall be binding upon any
          person holding by, under or through Tenant.

     (d)  Rent from Assignee or Sublessee.  In the event of any sublease or
          -------------------------------
          assignment to which Landlord's consent is requested and given,
          Landlord and Tenant shall share on an equal basis the rent paid by
          Tenant's sublessee or assignee which is in excess of the rent due
          under this Lease, on a per rentable square foot basis, after deducting
          all of Tenant's out-of-pocket costs incurred in connection with such
          sublease or assignment, including commissions, improvements and
          leasing concessions, which costs shall be amortized over the term of
          the sublease or assignment.  Landlord may, at its election, collect
          rent directly from such assignee, and in the event of a default
          hereunder by Tenant, from any sublessee.

     (e)  Landlord's Right to Recapture the Premises.  Except as set forth in
          ------------------------------------------
          the last sentence of this Section 18(e), with respect to any requested
          subletting or assignment requiring Landlord's consent, Landlord may,
          by written notice to Tenant, elect to terminate this Lease with
          respect to, and recapture from Tenant, that portion of the Premises
          specified in the request for sublease or assignment, as of the
          proposed effective date of the sublease or assignment.  In such event,
          the area of the Premises, as defined in this Lease, shall be decreased
          by the portion of the Premises specified in such request, and the
          monthly base rent, Tenant's Percentage of the Building and all other
          amounts in this Lease based on the area of the Premises shall be
          reduced appropriately.  If Tenant requests Landlord's consent to a
          sublease of the Premises, Landlord shall not have the right to
          recapture that portion of the Premises specified in the request for
          sublease unless the term of the sublease extends into the last twelve
          (12) months of the then-current term of this Lease, as extended from
          time to time.

19.  Holdover.  If Tenant, without the written consent of Landlord, holds over
     after the expiration or termination of the term of this Lease, Tenant shall
     be deemed to be occupying the Premises on a month-to-month tenancy, which
     tenancy may be terminated as provided by the laws of the State of
     Washington.  During such tenancy, Tenant agrees to pay to Landlord rent
     equal to one hundred fifty percent (150%) of the rent as set forth herein,
     unless a different rate shall be agreed upon, and to be bound by all of the
     terms, covenants and conditions herein specified, so far as applicable.

20.  Surrender of Premises. Upon the expiration or sooner termination of the
     term of this Lease, whether by lapse of time or otherwise, Tenant shall
     promptly and peacefully surrender the Premises to Landlord, and shall
     return to Landlord all keys thereto.

21.  Removal of Property.  Upon the expiration or sooner termination of this
     Lease, Tenant may remove its trade fixtures, office supplies and movable
     office furniture and equipment provided (a) such removal is made prior to
     the termination or expiration of this Lease, (b) Tenant is not in default
     under any provision of this Lease beyond any applicable notice and cure
     periods at the time of such removal, and (c) Tenant immediately repairs all
     damage caused by or resulting from such removal.  If Tenant has, in
     connection with its lease of the Premises, elected to upgrade the generator
     that Landlord would otherwise have

                                      -17-
<PAGE>

     provided to operate the life safety systems of the Building, then upon the
     expiration or sooner termination of this Lease, Landlord may retain such
     generator by paying to Tenant the depreciated value of the generator based
     on a fifteen (15) year useful life and the actual cost of such generator,
     including sales tax, less the amount that would be the depreciated value of
     the generator based on a fifteen (15) year useful life and a purchase price
     of $64,000.00 plus sales tax. All other property in the Premises and any
     alterations or additions thereto (including, without limitation, wall-to-
     wall carpeting, paneling, wall covering, or lighting fixtures and
     apparatus) and any other article affixed to the floor, wall or ceiling of
     the Premises shall become the property of Landlord and shall remain upon
     and be surrendered with the Premises, Tenant hereby waiving all rights to
     any payment or compensation therefor. If, however, Landlord so requests in
     writing, Tenant shall, upon termination of this Lease, remove such
     alterations, additions, fixtures, equipment and property placed or
     installed by Tenant in the Premises subsequent to the completion of the
     tenant improvements to be made pursuant to Exhibit E and to which Landlord
                                                ---------
     withheld its consent under the terms of Section 13 above, and shall
     immediately repair any damage caused by or resulting from such removal to
     the condition of the Premises prevailing upon commencement of this Lease,
     reasonable wear and tear excepted.

     If Tenant fails to remove any of its property of any nature whatsoever from
     the Premises or the Building at the termination of this Lease or when
     Landlord has the right of reentry, Landlord may, at its option, remove and
     store said property without liability for loss thereof or damage thereto,
     such storage to be for the account and at the expense of Tenant. If Tenant
     does not pay the cost of storing any such property after it has been stored
     for a period of thirty (30) days or more, Landlord may, at its option, sell
     or permit to be sold any or all of such property at public or private sale
     (and Landlord may become a purchaser at such sale), in such manner and at
     such times and places as Landlord in its reasonable discretion may deem
     proper without notice to Tenant, and shall apply the proceeds of such sale:
     first, to the cost and expense of such sale, including reasonable
     attorneys' fees actually incurred; second, to the payment of the costs or
     charges for storing any such property; third, to the payment or any other
     sums of money which may then be or thereafter become due Landlord from
     Tenant under any of the terms hereof; and fourth, the balance, if any, to
     Tenant.

22.  Defaults.

     (a)  Tenant's Defaults.  Time is of the essence hereof, and in the event
          -----------------
          Tenant violates or breaches or fails to keep or perform any covenant,
          agreement, term or condition of this Lease, and if such default or
          violation continues or is not remedied within five (5) business days
          (or, if no default in the payment of money is involved, then within
          twenty (20) days, or if such breach cannot be cured within twenty (20)
          days, then Tenant commences a cure within twenty (20) days and
          thereafter diligently prosecutes such cure to completion) after notice
          in writing thereof is given by Landlord to Tenant specifying the
          matter claimed to be in default, or if Tenant abandons or vacates the
          Premises or any significant portion thereof, Landlord, at its option,
          may immediately declare Tenant's rights under this Lease terminated,
          and reenter the Premises using such force as may be necessary, and
          repossess itself thereof, as of its former estate, and remove all
          persons and property from the Premises.  Notwithstanding any such
          reentry, the liability of Tenant for the full payment of rent and
          other amounts owed hereunder or provided for herein shall not be
          extinguished for the balance of this Lease, and Tenant shall make good
          to Landlord any deficiency arising from a reletting of the Premises at
          a lesser rent, plus the reasonable costs and expenses of renovating,
          altering and reletting the Premises, including attorneys' fees or
          brokers' fees incident to Landlord's reentry or reletting.  Tenant
          shall pay any such deficiency each month as the amount thereof is
          ascertained by Landlord or, at Landlord's option, Landlord may
          recover, in addition to any other sums, the amount at the time of
          judgment by which the unpaid rent for the balance of the term after
          judgment exceeds the amount of rental loss which Tenant proves could
          be reasonably avoided, discounted at the then Federal Discount Rate
          less three percent (3%).  The calculation of any amount of rental loss
          which Tenant claims could be reasonably avoided shall take into
          account those sums which are reasonably anticipated to be expended by
          Landlord for tenant improvements, moving expenses, lease assumption
          costs, real estate commissions, and all other

                                      -18-
<PAGE>

          costs associated with reletting the Premises. In reletting the
          Premises, Landlord may grant rent concessions and Tenant shall not be
          credited therefor. Nothing herein shall be deemed to affect the right
          of Landlord to recover for indemnification under Section 17 herein
          arising prior to the termination of this Lease, or for any other
          remedy at law or in equity. Landlord shall make reasonable efforts to
          mitigate its damages in the event of Tenant's default.

     (b)  Landlord's Defaults.  If Landlord fails to keep and perform any
          -------------------
          covenants and agreements herein contained, and if after written notice
          from Tenant specifying such default and permitting Landlord at least
          thirty (30) days (except in the event of an emergency or a situation
          affecting the tenantable condition of the Premises, in which case
          Landlord will be permitted a reasonable time under the circumstances)
          to remedy same Landlord has failed to remedy such default, then Tenant
          may, but shall not be obligated to, remedy such default.  Landlord
          shall reimburse Tenant for all reasonable costs and expenses incurred
          by Tenant in remedying such default, and such reimbursement shall be
          made within thirty (30) days of Landlord's receipt of an invoice for
          the amount of such costs and expenses.  All rights and remedies of
          Tenant under this Lease are cumulative and are not exclusive of any
          other rights and remedies provided to Tenant under applicable law.

23.  Right to Perform.  If Tenant fails to pay any sum of money, other than
     rent, required to be paid by it hereunder or fails to perform any other act
     on its part to be performed hereunder, and such failure continues for five
     (5) business days after written notice thereof by Landlord, or such shorter
     time if reasonable under the circumstances, Landlord may, but shall not be
     obligated so to do, and without waiving or releasing Tenant from any
     obligations of Tenant, make any such payment or perform any such other act
     on Tenant's part to be made or performed as provided in this Lease.
     Landlord shall have (in addition to any other right or remedy of Landlord)
     the same rights and remedies in the event of the nonpayment of sums due
     under this section as in the case of default by Tenant in the payment of
     rent.

24.  Nonwaiver.  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.  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 the 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.

25.  Costs and Attorneys' Fees.  In the event of any action or proceeding
     arising out of or in connection with this Lease, the substantially
     prevailing party shall be entitled to all costs, expenses and reasonable
     attorneys' fees, with or without suit and on appeal.

26.  Priority.  Tenant agrees that this Lease will be subordinate to any
     mortgage, deed of trust or other lien covering the Premises, upon and
     subject to the following terms and conditions: Tenant's subordination
     hereunder is expressly conditioned on execution and delivery to Tenant by
     each mortgagee, each lienholder and each beneficiary of a deed of trust, of
     a nondisturbance agreement reasonably acceptable to Tenant.  Such agreement
     shall be in a form typically used for commercial tenancies, shall be in
     recordable form and shall recognize Tenant's rights under this Lease in the
     event Landlord's interest is terminated while this Lease is in full force
     and effect.  Such nondisturbance agreement shall include, among other
     things, a provision to the effect that in the event of a termination of the
     ground or underlying lease or foreclosure of the mortgage, deed of trust or
     other lien in favor of said secured party, or upon a sale of the property
     encumbered thereby pursuant to the trustee's power of sale contained
     therein, or upon a transfer of the Building or the Premises by deed in lieu
     of foreclosure, then for so long as Tenant is not in material default under
     the terms, covenants, and conditions of this Lease, this Lease shall
     continue in full force and effect as a direct lease between the owner or
     succeeding owner of the Premises or the Building (as appropriate), as
     Landlord, and Tenant for the balance of the term of this Lease, upon and
     subject to all of the terms, covenants and conditions of this Lease.  Such
     nondisturbance agreement shall not include any terms which are inconsistent
     with the terms of this Lease or which adversely affect Tenant's rights or
     increase Tenant's obligations under this Lease.  Tenant's obligations under
     this Lease are conditioned upon Landlord

                                      -19-
<PAGE>

     obtaining, simultaneously with the execution of this Lease, a
     nondisturbance agreement from all mortgagees currently holding liens on the
     Property.

     Upon request by Landlord or the landlord under a ground lease or an
     underlying lease, or the holder of any mortgage, lien or deed of trust now
     existing or that may hereafter be placed upon the Land, Premises or the
     Building, Tenant will promptly execute a Subordination, Attornment, Notice
     and Non-Disturbance Agreement substantially in the form attached as Exhibit
                                                                         -------
     J to this Lease, as it may be amended by Landlord's mortgagee.
     -

27.  Estoppel Certificates.  Landlord and Tenant shall, at any time and from
     time to time during any term of the Lease, upon not less than fifteen (15)
     days' prior written request from the other, execute, acknowledge and
     deliver to the other or its designee a statement in writing certifying: (1)
     the date this Lease was executed and the date it expires; (2) the date of
     occupancy; (3) the amount of minimum monthly rent and the date to which
     such rent has been paid; (4) that this Lease is unmodified and in full
     force and effect (or, if modified, stating with specificity the nature of
     such modification); (5) that this Lease represents the entire agreement
     between the parties as to this leasing; (6) that there is not, to its
     knowledge, any default by the other hereunder, or, if any default is
     alleged, then specifying such default; (7) that on that date there are no
     existing defenses or offsets which that party has against the enforcement
     of this Lease by the other; and (8) that no security has been deposited
     with Landlord (or, if so, the amount thereof).  Any such statement shall be
     provided by the party requesting its completion, and such statement may be
     conclusively relied upon by any prospective purchaser or encumbrancer of
     the Premises or assignee or encumbrancer of Tenant's interest under this
     Lease.  In the event of the failure to deliver such statement within such
     time, the requested party shall be conclusively deemed to have admitted the
     accuracy of any information supplied by the requestor to a prospective
     purchaser or mortgagee related to any of the matters described in (1)
     through (8) above, and such admission may be conclusively relied upon by
     any prospective purchaser or encumbrancer of the Premises or assignee or
     encumbrancer of Tenant's interest under this Lease.

28.  Transfer of Landlord's Interest.  This Lease is assignable by Landlord
     without the consent of Tenant.  In the event of any transfer or transfers
     of Landlord's interest in the Premises or the Building, other than a
     transfer for security purposes only, the transferor will be automatically
     relieved of any and all obligations and liabilities on the part of Landlord
     accruing from and after the date of such transfer, and Tenant agrees to
     attorn to the transferee, providing such transferee assumes the obligations
     of Landlord under this Lease.

29.  Condemnation.  If all of the Premises, or such portions of the Building as
     may be required for the reasonable use of the Premises, are taken by
     eminent domain, this Lease will automatically terminate as of the date
     Tenant is required to vacate the Premises and all rents will be paid to
     that date.  In case of a taking of a part of the Premises equal to less
     than twenty percent (20%) of the floor area, or a portion of the Building
     not required for the reasonable use of the Premises, this Lease will
     continue in full force and effect and the rent will be equitably reduced
     based on the proportion by which the floor area of the Premises is reduced,
     such rent reduction to be effective as of the date possession of such
     portion is delivered to the condemning authority.  In case of a taking of a
     part of the Premises equal to twenty percent (20%) or more of the floor
     area, Tenant may elect to terminate this Lease.  Landlord reserves all
     rights to receive monetary damages to the Premises for any taking by
     eminent domain, and Tenant hereby assigns to Landlord any right Tenant may
     have to such damages or award; and Tenant shall make no claim against
     Landlord for damages for termination of the leasehold interest or
     interference with Tenant's business.  Tenant shall have the right, however,
     to claim and recover from the condemning authority compensation for any
     loss to which Tenant may be put for Tenant's moving expenses, provided that
     such damages may be claimed only if they are awarded separately in the
     eminent domain proceedings and not as part of the damages recoverable by
     Landlord.

30.  Advertising.  Tenant shall not inscribe any inscription, or post, place or
     in any manner display any sign, notice, picture, placard or poster, or any
     advertising matter whatsoever, anywhere in or about the Premises or the
     Building at places visible (either directly or indirectly as an outline or
     shadow on a glass pane) from anywhere outside the Premises without first
     obtaining Landlord's written consent thereto, which consent

                                      -20-
<PAGE>

     shall not be unreasonably withheld. Any such consent by Landlord shall be
     upon the understanding and condition that Tenant, at its sole cost and
     expense, will remove the same at the expiration or sooner termination of
     this Lease and will repair any damage to the Premises or the Building
     caused thereby. Notwithstanding the foregoing, Landlord hereby grants
     Tenant the non-exclusive right to install signs on the monument sign
     adjacent to the Building. Tenant's right to do so is subject to City of
     Bellevue regulations, the installation being completed in a good and
     workmanlike manner, and Landlord's review and approval of the design and
     location of the signs, which approval shall not be unreasonably withheld.
     The design, construction, installation and removal of all signs is at the
     sole cost and expense of Tenant.

31.  Exterior Signage. So long as Tenant occupies a minimum of three (3) full
     floors in the Building, Tenant shall have the sole and exclusive right to
     install signage on the north and west sides of the exterior of the
     Building, subject to Landlord's reasonable approval and all applicable
     codes. All costs associated with installing exterior signage on the
     Building shall be borne by Tenant. Tenant may, however, include the cost of
     installing exterior signage on the Building as an item for which payment is
     to be made from the Tenant Improvement Allowance (defined in Section 33
     below).

32.  Parking. Parking shall at all times be governed by reasonable rules and
     regulations established by Landlord, which may be changed with reasonable
     discretion from time to time.  Such rules and regulations shall not be
     inconsistent with the terms and conditions of this Lease and shall be
     enforced against all parking users in a non-discriminatory fashion.

     From 7:00 a.m. to 6:00 p.m., Monday through Friday, except for legal
     holidays, during the term of this Lease, as it may be extended, Landlord
     shall provide parking at a ratio of four (4) spaces per one thousand
     (1,000) rentable square feet of the Premises on a non-exclusive basis in
     the below ground and surface parking lots located on the real property
     comprising the Project and on which the 12600 Building is located.  A plan
     showing the parking available for the Project and the 12600 Building is
     attached hereto as Exhibit K.  Such parking shall be provided by Landlord
                        ---------
     at no additional charge during the Initial Lease Term (except for the
     payment of any parking tax subsequently imposed by a governmental
     authority), Landlord represents and warrants to Tenant that Landlord is
     unable to provide parking to Tenant on an exclusive basis at any time
     during the Lease term. If Tenant experiences a problem with the parking at
     the Building such that Tenant's allotted parking spaces are unavailable to
     it on a consistent basis, and so informs Landlord, then Landlord shall take
     such measures, such as monitoring or valet parking, as are reasonably
     necessary to correct the problem, and such expenses shall be charged to
     Tenant as Additional Rent. Tenant acknowledges that the parking lot is used
     and may be used jointly by other tenants under a parking access agreement
     managed by Landlord.

33.  Tenant Improvements.

     (a)  Tenant Improvement Allowance.  Landlord agrees to provide an allowance
          ----------------------------
          of up to Two Million Three Hundred Twenty-five Thousand Seven Hundred
          Sixty-five Dollars ($2,325,765.00) (the "Tenant Improvement
          Allowance") to assist Tenant in the build-out of the tenant
          improvements for the Premises (the "Tenant Improvements").   The
          Tenant Improvement Allowance is calculated by multiplying the agreed
          floor area of the Premises, in usable square feet (71,562) by $32.50.
          The Tenant Improvement Allowance may be adjusted based on the actual
          floor area of the Premises.  In addition to its use toward the hard
          costs of constructing the Tenant Improvements, the Tenant Improvement
          Allowance may be used for space planning and design, the cost of
          building permits, Washington State Sales Tax, cabling and wiring for
          the Premises and exterior building signage.  Tenant expressly assumes
          responsibility for the cost and payment of any portion of the Tenant
          Improvements that are in excess of the Tenant Improvement Allowance.

          Tenant may, by written notice delivered to Landlord no later than
          September 1, 2000, elect to amortize the cost of Tenant Improvements
          that are in excess of the Tenant Improvement Allowance, up to an
          additional $12.50 per usable square foot of the agreed floor area of
          the Premises, on a

                                      -21-
<PAGE>

          straight-line basis over a term of eight (8) years and based on an
          interest rate equal to Landlord's permanent loan rate on the Building
          plus one percent (1%); provided, however, that until such time as
          Landlord's permanent loan on the Building is in place, such
          amortization shall be based on the Bank of America prime rate plus one
          percent (1%). If Tenant elects to have any portion of cost of Tenant
          Improvements that are in excess of the Tenant Improvement Allowance
          amortized, as provided by the terms of the preceding sentence, then
          Tenant shall execute a promissory note in the form of Exhibit L
                                                                ---------
          attached to this Lease (the "TI Note"), evidencing a loan payable to
          Landlord for such amount. The monthly payments due under the TI Note
          shall be additional rent due under this Lease, and shall be added to
          the monthly base rent due from Tenant to Landlord under the terms of
          Section 1(f) above.

     (b)  Plans for Tenant Improvements.  Landlord and Tenant shall mutually
          -----------------------------
          agree on the selection of the architect (the "Architect") to plan,
          design and complete the construction documents for the Tenant
          Improvements, such approval not to be unreasonably withheld or
          delayed. Landlord shall pay for the cost of an initial "test fit" for
          one floor of the Premises by providing to Tenant an allowance of Two
          Thousand Seven Hundred Seventy-five Dollars ($2,775.00). Such
          allowance shall be a part of, and not in addition to, the Tenant
          Improvement Allowance set forth in Section 33(a) above. Prior to
          Landlord commencing work on the Tenant Improvements, Tenant shall
          submit to Landlord two (2) copies of plans detailing the design and
          plan of improvements prepared by the Architect. Landlord shall either
          approve or disapprove plans within ten (10) days and, if approved,
          return a signed, approved copy to Tenant. In the event that Landlord
          does not approve the plans, Landlord shall inform Tenant of the
          reasons for its disapproval and Tenant shall have ten (10) days in
          which to submit revised plans to Landlord for approval. Tenant shall
          not unreasonably refuse to satisfy any objections made by Landlord to
          the plans and specifications. Any objections Tenant has to Landlord's
          objection shall be submitted to Landlord in writing within the ten
          (10) day period. A failure of one party to give any notice to the
          other party within the ten (10) day period shall be deemed to
          constitute approval of the plans and specifications or the objections
          thereto, as appropriate. Landlord shall not unreasonably withhold or
          delay its approval of Tenant's plans for Tenant Improvements.

     (c)  Construction of Tenant Improvements.  Upon Landlord's approval of
          -----------------------------------
          Tenant's plans, Landlord shall enter into a construction contract with
          Gall Landau Young ("GLY") for the construction of the Tenant
          Improvements.

          Landlord will guaranty the delivery dates for the Premises, on a floor
          by floor basis, set forth in Section 1(e) above, and shall be subject
          to the penalties set forth in Section 40 for failure to so deliver the
          Premises, if Tenant complies with the following dates regarding
          delivery of items necessary for construction of the Tenant
          Improvements:

          (1)   March 15, 2000:      begin preparation of design and drawings
                                     for the Tenant Improvements;
          (2)   June 1, 2000:        submit the plans for Tenant Improvements to
                                     the City of Bellevue for a preliminary
                                     permit;
          (3)   July 1, 2000:        finalize construction drawings for the
                                     Tenant Improvements; and
          (4)   August 10, 2000:     approval of bid price for construction of
                                     the Tenant Improvements by Landlord and
                                     Tenant, which approval shall not be
                                     unreasonably withheld.

          If Tenant does not comply with the dates set forth above, then the
          dates for delivery of the Premises set forth in Section 1(e) above
          shall, on a floor-by-floor basis, be moved back one day for each day
          that Tenant fails to meet its delivery date for any item.

         The construction of all improvements to be made on the Premises shall
         be performed in a first-class, workmanlike manner, in conformity with
         all applicable governmental laws, ordinances, rules, orders,
         regulations and other requirements, and in substantial accordance with
         plans and specifications.

         Tenant or Tenant's agents shall have the right to inspect the
         construction of the Tenant Improvements during the progress thereof at
         Tenant's sole cost and expense and at times

                                      -22-
<PAGE>

         coordinated with Landlord and GLY. If, during the progress of
         construction of the Tenant Improvements, Tenant desires to have any
         changes made to the approved plans and specifications, then Landlord
         shall cause GLY to prepare and deliver to Tenant's designated
         representative a change order showing the cost therefor and the
         additional time necessary for substantial completion of the Tenant
         Improvements, if any. Tenant shall promptly inform Landlord and GLY
         whether such change order has been approved by Tenant. The dates for
         delivery of the Premises set forth in Section 1(e) above shall, on a
         floor-by-floor basis, be moved back one day for each additional day
         that a change order approved by Tenant will require.

34.  Tenant's Approval Regarding Construction and Design of Building.  Tenant
     has reviewed and approved the plans and specifications for the Building, as
     the same are described on Exhibit D attached hereto (the "Building Plans").
                               ---------
     With respect to any material changes to material design elements that
     Landlord desires to make to the Building Plans, Landlord shall notify
     Tenant of the nature of such material changes, and Tenant shall, within
     three (3) business days after receipt of such notice, inform Landlord
     whether it approves such material changes.  Tenant shall not unreasonably
     withhold its consent to any material change to the Building Plans.
     Additionally, if the Building Plans are not specific as to some of the
     material design elements of the Building, then Landlord shall consult with
     Tenant and obtain Tenant's approval with respect thereto.  Tenant shall not
     unreasonably withhold its consent to Landlord's plans for any material
     design elements of the Building.

35.  Installation of Satellite Dishes on Roof of Building.  Landlord hereby
     grants to Tenant, for no additional rent during the term of this Lease, as
     it may be extended, the exclusive use of up to fifty percent (50%) of the
     usable area of the roof of the Building on which to install and maintain
     satellite dishes and/or antennas, as shown by the cross-hatched area on
     Exhibit M-1 attached to this Lease.  If at any time during the Lease term,
     -----------
     Tenant occupies less than two (2) full floors of the Building, then the
     usable area of the roof designated for Tenant's exclusive use and for no
     additional rent shall decrease to twenty-five percent (25%) of the usable
     area of the roof of the Building, as shown by the cross-hatched area on
     Exhibit M-2 attached to this Lease.  The right to use the roof for the
     -----------
     installation and maintenance of satellite dishes and/or antennas is
     personal to Tenant (or Tenant's successor-in-interest through merger), and
     Tenant may not sublet or assign its right to use the roof of the Building,
     except to an assignee approved by Landlord or to a sublessee occupying at
     least 10,000 rentable square feet of the Premises, in which case Tenant may
     grant to such sublessee the right to use a pro rata share of Tenant's area
     of the roof.  The installation and maintenance of such satellite dishes
     and/or antennas shall be at Tenant's sole cost and expense, and is
     conditioned on Tenant's (and any sublessee's) compliance with the terms of

36.  Fifth Floor Hold Period.  Landlord shall not, for the period commencing
     upon the execution of this Lease and expiring as of 11:59 p.m. on October
     2, 2000, market for lease the premises comprised of the Fifth Floor of the

37.  Terms Applicable to Expansion of Premises During Initial 12 Months.  If
     Tenant and Landlord, prior to the expiration of twelve (12) months

     agreement to expand the Premises such that the Premises will consist of
     space in the Building in addition to the floor area of the first, second,
     third and fourth floors, then such additional floor area shall be added to

     Lease, including all economic terms set forth herein, and the lease term
     with respect to such additional floor area shall expire on the expiration

     applicable to any expansion space, up to an additional $12.50 per usable
     square foot, then Tenant shall provide written notice to Landlord of its
     election by October 1, 2001, and execute a promissory note in the form of
     the TI Note evidencing a loan payable to Landlord for such amount.  The
     monthly payments due under the TI Note shall be calculated based on the
     then-remaining portion of the 8-year period of any TI Note executed
     pursuant to the terms of Section 33(a) above, shall be additional rent due
     under this Lease, and shall be added to the monthly base rent due from

38.  Tenant's Right of First Offer.

     (a)  Right of First Offer.  Landlord hereby grants to Tenant, during the
          --------------------
          Initial Lease Term, a continuing right of first offer (the "Right of
          First Offer") to lease all available space in the Building, whether
          such space is currently available or becomes available during the
          Initial Lease Term.  In the event any space becomes available to
          lease, Landlord shall provide Tenant with a written notice of
          availability (the "Availability Notice").  The Availability Notice
          shall identify the space (the "ROFO Space"), the date on which it will
          be available, and the economic terms applicable to the ROFO Space
          (which economic terms shall be determined in accordance with Section
          37 above if the Availability Notice either may or must be accepted by
          Tenant prior to the expiration of the twelve (12) month period
          following the first Commencement Date under this Lease).  Tenant shall
          have ten (10) business days following receipt of the Availability
          Notice in which to exercise its Right of First Offer by giving written
          notice of such exercise to Landlord.  If Tenant exercises its Right of
          First Offer within ten (10) business days following receipt of the
          Availability Notice or under the terms of Section 37 above, as
          applicable, then Landlord and Tenant shall promptly enter into an
          amendment to this Lease adding the ROFO Space to the Premises as of
          the date of availability and on the terms specified in the
          Availability Notice.  If Tenant fails to exercise its Right of First
          Offer within ten (10) business days following receipt of the
          Availability Notice, then Landlord may lease the ROFO Space to third
          parties on terms and conditions equal to not less than ninety-five
          percent (95%) of the economic value of the terms proposed to Tenant.
          If Landlord desires submit to an offer to a third party, or receives
          an offer from a third party that it is willing to accept, and the
          economic value of such offer is less than ninety-five percent (95%) of
          that last offered to Tenant, or if Landlord has not entered into a
          binding lease for such space within six (6) months after the
          Availability Notice for such space was delivered to Tenant, then
          Tenant shall again have a Right of First Offer with respect to such
          space and the new economic terms.

     (b)  Expansion of Right of First Offer to Other Buildings.  At such time as
          ----------------------------------------------------
          (1) the Premises are comprised of more than 70,000 rentable square
          feet, or (2) Tenant cannot, based on the remaining space available
          within the Building, expand by at least 10,000 rentable square feet
          within the Building, then the Right of First Offer set forth in
          Section 38(a) above shall also apply to (i) space available for lease
          in Sterling Plaza I, and (ii) any spaces in excess of 5,000 square
          feet available for lease in the 12600 Building (even if a portion of
          such space containing less than 5,000 square feet is offered to third
          parties), subject only to rights of existing tenants in Sterling Plaza
          I and the 12600 Building that are in existence as of the date of this
          Lease.

     (c)  Termination of Rights.  Tenant's Right of First Offer shall terminate
          ---------------------
          if: (1) Tenant assigns its interest in this Lease to a party other
          than a successor-in-interest by merger or reorganization; or (2)
          Tenant subleases a portion of the Premises constituting either (A)
          more than thirty-three percent (33%) of the then-existing floor area
          of the Premises, or (B) more than 44,000 rentable square feet, unless
          in either of cases (A) or (B) above such sublease(s) is/are for a term
          of two (2) years or less.

39.  Option to Cancel Lease.

     (a)  Tenant's Option to Cancel.  Subject to delays by Tenant or Tenant's
          -------------------------
          agents and delays due to labor disputes, fire, adverse weather, force
          majeure events or other causes that are beyond Landlord's control,
          Landlord hereby grants to Tenant the option to cancel this Lease (the
          "Option to Cancel") following the occurrence of any of the following:
          (1) Tenant fails to merge with Stamps.com, Inc. on or before March 10,
          2000; (2) Landlord fails to obtain a building permit for the Building
          from the City of Bellevue on or before March 21, 2000; (3) Landlord
          has not commenced construction of the Building on or before April 1,
          2000 (such commencement being defined as the beginning of excavation);
          or (4) the Building and Premises (including Tenant Improvements) are
          not

                                       24
<PAGE>

          substantially complete by April 1, 2001. Tenant shall exercise its
          Option to Cancel by giving written notice to Landlord specifying the
          event giving rise to Tenant's Option to Cancel.

     (b)  Landlord's Option to Cancel.  Landlord may, by giving written notice
          ---------------------------
          to Tenant, cancel this Lease if either (1) Tenant fails to merge with
          Stamps.com, Inc. on or before March 10, 2000; (2) Landlord has not
          obtained a building permit for the Building from the City of Bellevue
          on or before the date that is two (2) weeks following the date on
          which Tenant informs Landlord in writing that the merger with
          Stamps.com, Inc. has occurred.

     (c)  Effect of Cancellation of Lease.  If either party validly exercises
          -------------------------------
          its option to cancel this Lease under this Section 39, then neither
          party shall have any further rights or obligations hereunder (except
          those obligations which expressly survive the expiration or
          termination of this Lease), and Landlord shall promptly return to
          Tenant any prepaid rent or security instrument previously given by
          Tenant to Landlord in connection with this Lease.  Tenant acknowledges
          that it will, in such event, be responsible for the cost of any
          drawings prepared or permits obtained in connection with the Tenant
          Improvements.

40.  Delay in Lease Commencement; Additional Options to Cancel Lease.

     (a)  Rent Credit for Delay in Lease Commencement.  If neither Landlord nor
          -------------------------------------------
          Tenant has exercised its option to cancel this Lease as set forth in
          Section 39 above, and taking into account on a day-for-day basis any
          delays caused by Tenant or Tenant's agents under Section 33 above or
          otherwise, labor disputes, fire, adverse weather, force majeure events
          or other causes that are beyond Landlord's control, the Premises
          (including the Tenant Improvements) are not substantially complete by:

          (1)  April 1, 2001, then for each day after April 1, 2001, and through
               April 30, 2001, that the Building and the Premises, on a floor-
               by-floor basis, are not substantially complete, Tenant shall, on
               a floor-by-floor basis, receive a rent credit equal to one-half
               day's rent for each floor of the Premises not yet delivered; and

          (2)  April 30, 2001, then for each day after April 30, 2001, that the
               Building and the Premises, on a floor-by-floor basis, are not
               substantially complete, Tenant shall, on a floor-by-floor basis,
               receive a rent credit equal to one day's rent for each floor of
               the Premises not yet delivered.

          In no event, however, shall the amount of the rent to be credited to
          Tenant under this Section 40(a) exceed Five Hundred Thousand Dollars
          ($500,000.00).

  (b) Additional Options to Cancel Lease.
      ----------------------------------

          (1)  Tenant's Additional Option to Cancel.  If, for any reason other
               ------------------------------------
               than delays caused by Tenant, Tenant is unable to occupy the
               entire Premises (except any portions added to the original
               Premises under the terms of Sections 37 and 38 above) by December
               31, 2001, then Tenant may, by written notice to Landlord so
               stating, cancel this Lease.

          (2)  Landlord's Additional Option to Cancel.  If, due to any delays in
               --------------------------------------

               control, Tenant is unable to occupy the entire Premises (except
               any portions added to the original Premises under the terms of
               Sections 37 and 38 above) by December 31, 2001, then Landlord
               may, by written notice to Tenant so stating, cancel this Lease.

          (3)  Effect of Cancellation of Lease.  If either party validly
               -------------------------------
               exercises its option to cancel this Lease under this Section
               40(b), then neither party shall have any further rights or

                                       25
<PAGE>

               obligations hereunder (except those obligations which expressly
               survive the expiration or termination of this Lease), and
               Landlord shall promptly return to Tenant any prepaid rent or
               security instrument previously given by Tenant to Landlord in
               connection with this Lease.  Tenant acknowledges that it will, in
               such event, be responsible for the cost of any drawings prepared
               or permits obtained in connection with the Tenant Improvements.

41.  American With Disabilities Act (ADA) Compliance.  Landlord and Tenant
     acknowledge that, in accordance with the provisions of the Americans With
     Disabilities Act (the "ADA"), responsibility for compliance with the terms
     and conditions of Title III of the ADA may be allocated as between Landlord
     and Tenant.  Notwithstanding anything to the contrary contained in the
     Lease, Landlord and Tenant agree that the responsibility for compliance
     with the ADA (including, without limitation, the removal of architectural
     and communications barriers and the provision of auxiliary aids and
     services to the extent required) following substantial completion of the
     Building shall be allocated as follows: (a) Tenant shall, at Tenant's sole
     cost and expense, be responsible for compliance with the provisions of
     Title III of the ADA for any construction, renovations, alterations and
     repairs made within the Premises (except restrooms and elevators), whether
     such construction, renovations, alterations and repairs are completed by
     Landlord or Tenant and whether at Landlord's or Tenant's expense; and (b)
     Landlord shall, at Landlord's sole cost and expense, be responsible for
     compliance with the provisions of Title III of the ADA for (1) restrooms
     and elevators in the Building; (2) all areas of the Building which are
     exterior to the Premises (unless such renovations and alterations are
     required due to Tenant's particular use of such areas), and (3) all of the
     remaining portions of the Land.  Landlord agrees to indemnify and hold
     Tenant harmless from and against any claims, damages, costs and liabilities
     arising out of Landlord's failure, or alleged failure, as the case may be,
     to comply with its obligations under this Section 41, which indemnification
     obligation shall survive the expiration or termination of this Lease.
     Tenant agrees to indemnify and hold Landlord harmless from and against any
     claims, damages, costs and liabilities arising out of Tenant's failure, or
     alleged failure, as the case may be, to comply with its obligations under
     this Section 41, which indemnification obligation shall survive the
     expiration or termination of this Lease.

     Landlord and Tenant each agree that the allocation of responsibility for
     ADA compliance shall not require Landlord or Tenant to supervise, monitor
     or otherwise review the compliance activities of the other with respect to
     its assumed responsibilities for ADA compliance as set forth in this
     Section 41.

42.  Hazardous Materials.  As used in this Lease, "Hazardous Materials" means
     any substance which is (i) designated, defined, classified or regulated as
     a hazardous substance, hazardous material, hazardous waste, pollutant or
     contaminant under any Environmental Law, as currently in effect or as
     hereafter amended or enacted, (ii) a petroleum hydrocarbon, including crude
     oil or any fraction thereof and all petroleum products, (iii) PCBs, (iv)
     lead, (v) asbestos, (vi) flammable explosives, (vii) infectious materials,
     or (viii) radioactive materials. "Environmental Law(s)" means the
     Comprehensive Environmental Response, Compensation, and Liability Act of
     1980, 42 U.S.C. Sections 9601, et seq., the Resource Conservation and
                                    -- ---

                                                   -- ---
     33 U.S.C. Sections 1251, et seq., and the Washington Model Toxics Control
                              -- ---
     Act, Revised Code of Washington Chapter 70.105D, as said laws have been
     supplemented or amended to date, the regulations promulgated pursuant to
     said laws and any other federal, state or local law, statute, rule,
     regulation or ordinance which regulates or proscribes the use, storage,
     disposal, presence, clean-up, transportation or release or threatened
     release into the environment of Hazardous Material.

     Tenant shall not cause, or allow any of Tenant's employees, agents,
     customers, visitors, invitees, licensees, contractors, assignees and
     subtenants to cause, any Hazardous Materials to be handled, used,
     generated, stored, released or disposed of in, on, under or about the
     Premises, the Building or the Project or surrounding land or environment in
     violation of any Environmental Laws.  Tenant must obtain Landlord's written
     consent prior to the introduction of any Hazardous Materials onto the
     Premises, the Building or the Project.  Notwithstanding the foregoing,
     Tenant may handle, store, use and dispose of products containing small
     quantities of Hazardous Materials for "general office purposes" (such as
     toner for copiers) to the

                                       26
<PAGE>

     extent customary and necessary for the Permitted Materials in a safe and
     lawful manner and never allow such Hazardous Materials to contaminate the
     Uses of the Premises; provided that Tenant shall always handle, store, use,
     and dispose of any such Hazardous Premises, Building, or Project or
     surrounding land or environment. Tenant shall immediately notify Landlord
     in writing of any Hazardous Materials' contamination of any portion of the
     Premises, the Building or the Project of which Tenant becomes aware,
     whether or not caused by Tenant. Landlord shall have the right at all
     reasonable times to inspect the Premises and to conduct tests and
     investigations to determine whether Tenant is in compliance with the
     foregoing provisions, the costs of all such inspections, tests and
     investigations to be borne by Tenant. Tenant shall indemnify, defend (by
     counsel reasonably acceptable to Landlord), protect and hold Landlord
     harmless from and against any and all claims, liabilities, losses, costs,
     loss of rents, liens, damages, injuries or expenses (including attorneys'
     and consultants' fees and court costs), demands, causes of action, or
     judgments directly or indirectly arising out of or related to the use,
     generation, storage, release, or disposal of Hazardous Materials by Tenant
     or any of Tenant's Parties in, on, under or about the Premises, the
     Building or the Project or surrounding land or environment, which indemnity
     shall include, without limitation, damages for personal or bodily injury,
     property damage, damage to the environment or natural resources occurring
     on or off the Premises, losses attributable to diminution in value or
     adverse effects on marketability, the cost of any investigation,
     monitoring, government oversight, repair, removal, remediation,
     restoration, abatement, and disposal, and the preparation of any closure or
     other required plans, whether such action is required or necessary prior to
     or following the expiration or earlier termination of this Lease. Neither
     the consent by Landlord to the use, generation, storage, release or
     disposal of Hazardous Materials nor the strict compliance by Tenant with
     all laws pertaining to Hazardous Materials shall excuse Tenant from
     Tenant's obligation of indemnification pursuant to this Section 42.
     Tenant's obligations pursuant to the foregoing indemnity shall survive the
     expiration or earlier termination of this Lease.

     Landlord represents and warrants, to the best of its knowledge without
     special inquiry, that no Hazardous Materials are being or have in the past
     been generated, treated or disposed of or at the Premises or the Building.
     Landlord shall not use, generate, treat, store or dispose of any Hazardous
     Materials on the Premises or in the Building except in accordance with all
     Environmental Laws. If Landlord breaches the obligations stated in the
     preceding sentence, or if the presence of Hazardous Materials on the
     Premises or Building caused by Landlord results in contamination of the
     Premises or Building, then Landlord shall indemnify, defend and hold Tenant
     harmless from any and all claims, judgments, damages, penalties, fines,
     costs, liabilities, or losses (including, without limitation, diminution in
     value of the Premises, damages for the loss or restriction on the use of
     Tenant's rentable or usable space, and sums paid in settlement of claims,
     attorneys' fees, consultant fees and expert fees) which arise during or
     after the Lease term as a result of Landlord's violation of Environmental
     Laws. The foregoing representations and warranties contained in this
     paragraph shall not be binding upon any mortgagee, and such mortgagee's
     successors and assigns, who holds a mortgage or deed of trust encumbering
     the Land and who succeeds to the interest of Landlord under this Lease as a
     result of foreclosure or otherwise, or upon any successor in interest to
     Landlord who purchases the interest of Landlord in the Land at a
     foreclosure sale conducted for the benefit of such mortgagee.

43.  Arbitration. If a dispute arises under this Lease, the parties shall
     proceed to resolve the dispute by arbitration in accordance with the
     provisions of this Section 43.

     The party desiring arbitration shall give written notice to that effect to
     the other party, specifying in the notice the nature of the dispute and the
     name and address of three persons acceptable to it to act as arbitrator on
     its behalf. Within five (5) business days after receipt of such notice, the
     other party shall give written notice to the first party, informing the
     first party if any of the arbitrators specified are acceptable, and if none
     are acceptable, submitting an additional three persons for consideration.
     If, within fifteen (15) days from the date of the first notice, the parties
     are unable to mutually agree on the person to serve as arbitrator, either
     party may apply to the presiding judge of the King County Superior Court to
     select the arbitrator.

                                       27
<PAGE>

     Within five (5) business days following selection of the arbitrator, each
     party shall furnish the arbitrator with its written position. Each party
     may also include at this time any information, data, and/or reports
     supportive of its position. The arbitrator may request additional
     information, data, or reports from the parties or others if the arbitrator
     so desires. Within fifteen (15) business days following the arbitrator's
     receipt of information from the parties, the arbitrator shall notify both
     parties in writing of the arbitrator's decision. The arbitrator is not
     empowered to award any damages in excess of actual, compensatory damages.
     The decision of the arbitrator shall be final and binding upon the parties
     and effective as of the date of notification to the parties of the
     arbitrator's decision.

     The arbitrator shall be an individual with at least ten (10) years
     substantial experience in managing and/or operating commercial real
     property.  Arbitration shall be conducted pursuant to the rules of the
     American Arbitration Association then in effect and the decision of the
     arbitrator may be entered and enforced as a judgment in accordance with the
     applicable laws of King County, Washington.  Each party shall bear its own
     attorneys' fees and expenses and shall share equally those of the
     arbitrator.  The place of arbitration shall be in either Bellevue or
     Seattle, Washington.

44.  Quiet Enjoyment.  Landlord warrants and covenants that, during all terms of
     this Lease, Tenant will have the exclusive right to possession and quiet
     enjoyment of the Premises and will have, hold and enjoy the Premises
     peacefully and quietly, without any manner of let, suit, trouble or
     hindrance so long as Tenant complies with all material provisions of this
     Lease.

45.  Execution of Lease by Landlord.  The submission of this document for
     examination and negotiation does not constitute an offer to lease, or a
     reservation of, or option for the Premises.  No act or omission of any
     employee or agent of Landlord or of Landlord's broker shall alter, change
     or modify any of the provisions hereof.

46.  Landlord's Liability.  Anything in this Lease to the contrary
     notwithstanding, covenants, undertakings and agreements herein made on the
     part of Landlord are made and intended not as personal covenants,
     undertakings and agreements or for the purpose of binding Landlord
     personally or the assets of Landlord except Landlord's interest in the
     Premises and the Building and the proceeds thereof, but are made and
     intended for the purpose of binding only Landlord's interest in the
     Premises and the Building and the proceeds thereof.  No personal liability
     or personal responsibility is assumed by, nor shall at anytime be asserted
     or enforceable against Landlord or its partners and their respective heirs,
     legal representatives, successors and assigns on account of this Lease or
     on account of any covenant, undertaking or agreement of Landlord contained
     in this Lease.

corporation ("Guarantor"), to and for the benefit of STERLING REALTY
ORGANIZATION CO., a Washington corporation ("Landlord"), with respect to that
certain Lease Agreement between Landlord and iSHIP.COM, a Washington corporation
and a wholly-owned subsidiary of Guarantor ("Tenant"), dated March 7, 2000 (the
"Lease").

     FOR VALUE RECEIVED and in consideration of and as an inducement to Landlord
entering into the Lease, Guarantor unconditionally and continuously guarantees
to Landlord, its successors and assigns, the full and timely performance and
observance by Tenant of all the terms and conditions of the Lease to be
performed and observed by Tenant.

     This Guaranty and the obligations of Guarantor hereunder shall not be
terminated or impaired by reason of the granting by Landlord of any indulgences
to Tenant or the assertion by Landlord against Tenant of any of Landlord's
rights or remedies under the Lease, or by the relief of Tenant from any of
Tenant's obligations under the Lease by operation of law or otherwise, whether
or not Guarantor has received notice of same.  Guarantor waives all suretyship
defenses and waives notice of any breach by Tenant.

     This Guaranty shall continue in full force and effect as to any renewal,
amendment, modification, extension, assignment or transfer of the Lease or any
subletting of the Lease premises, whether or not Guarantor shall have received
notice of or consented to the same.  The liability of Guarantor under this
Guaranty is primary and absolute, and Landlord may at its option proceed against
Guarantor without proceeding against Tenant.  Any action against Guarantor shall
be brought in King County, Washington.

     Landlord's delay or failure to insist upon the strict performance or
observance of any obligation of Tenant under the Lease or to exercise any right
or remedy available under the Lease or at law or in equity, shall not be
construed to be a waiver of Landlord's prerogative to insist upon such strict
performance or observance or to exercise any such right or remedy.  Receipt by
Landlord of rent or other payment with knowledge of a breach of any term or
condition of the Lease shall not be construed to be a waiver of such breach.

     The liability of Guarantor hereunder shall not be affected or limited by:
(a) the release or discharge of Tenant in any creditors', receivership,
bankruptcy or other proceedings; (b) the impairment, limitation or modification
of the liability of the Tenant or the estate of Tenant in bankruptcy, or of any
remedy for the enforcement of Tenant's liability under the Lease resulting from
the operation of any present or future provision of the federal bankruptcy laws
or other statutes or from the decision in any court; (c) the rejection or
disaffirmance of the Lease in any such proceedings; (d) any disability or other
defense of Tenant; or (e) the cessation, from any cause whatsoever, of the
liability of Tenant.

     Until all the terms, conditions and agreements of the Lease are fully
performed and observed by Tenant, Guarantor hereby waives the right to enforce
any claim, right or remedy which Guarantor now has or hereafter shall have
against Tenant by reason of any one or more payments or acts of performance in
compliance with the obligations of Guarantor hereunder, and Guarantor hereby
subordinates any liability or indebtedness of Tenant now or hereafter held by
Guarantor to the obligations of Tenant to Landlord under the Lease.

                                      G-1

     This Guaranty shall inure to the benefit of Landlord, its affiliates,
successors and assigns, and shall be binding upon the successors and assigns of
Guarantor.

     This Guaranty is irrevocable and may not be changed, affected, discharged
or terminated other than by an agreement in writing signed by Guarantor and
Landlord.

     Guarantor shall pay all costs and expenses paid or incurred by Landlord in
enforcing either the Lease or this Guaranty, including court costs and a
reasonable amount for legal services performed by counsel, whether employed or
retained by Landlord.

      or re-advances with interest thereon and to any mortgages or deeds of
      trust on the Property which may hereafter be held by Lender.

2.    Tenant Not to Be Disturbed. In the event it should become necessary to
      --------------------------
      foreclose the Mortgage or Lender should otherwise come into possession of
      title to the Property, Lender will not join Tenant in summary or
      foreclosure proceedings unless required by law in order to obtain
      jurisdiction, but in such event no judgment foreclosing the Lease will be
      sought, and Lender will not disturb the use and occupancy of Tenant under
      the Lease so long as Tenant is not in default under any of the terms,
      covenants or conditions of the Lease beyond any applicable notice and cure
      period and has not prepaid the rent except monthly in advance as provided
      by the terms of the Lease.

3.    Tenant to Attorn to Lender.  Tenant agrees that in the event any
      --------------------------
      proceedings are brought for foreclosure of the Mortgage, it will attorn to
      the purchaser as the landlord under the Lease.  The purchaser by virtue of
      such foreclosure shall be deemed to have assumed and agreed to be bound,
      as substitute landlord, by the terms and conditions of the Lease until the
      resale or other disposition of its interest by such purchaser, except that
      such assumption shall not be deemed of itself an acknowledgment by such
      purchaser of the validity of any then existing claims of Tenant against
      any prior landlord (including Landlord).  All rights and obligations under
      the Lease shall continue as though such foreclosure proceedings had not
      been brought, except as aforesaid.  Tenant agrees to execute and deliver
      to any such purchaser such further assurance and other documents,
      including a new lease upon the same terms and conditions of the Lease,
      confirming the foregoing as such purchaser may reasonably request.  Tenant
      waives the provisions (i) contained in the Lease or any other agreement
      relating thereto, and (ii) of any statute or rule of law now or hereafter
      in effect, which may give or purport to give it any right or election to
      terminate or otherwise adversely affect the Lease and the obligations of
      Tenant thereunder by reason of any foreclosure proceeding.

4.    Limitations.  Notwithstanding the foregoing, neither Lender nor such other
      -----------
      purchaser shall in any event be:

      (a) liable for any act or omission of any prior landlord (including
          Landlord) unless such nonperformance constitutes a default under the
          Lease and continues during the period of the Lender's or such other
          purchaser's ownership of the Property;

      (b) obligated to cure any defaults of any prior landlord (including
          Landlord) which occurred prior to the time that Lender or such other
          purchaser succeeded to the interest of such prior landlord under the
          Lease unless such default continues during the period of the Lender's
          or such other purchaser's ownership of the Property;

      (c) subject to any offsets or defenses which Tenant may be entitled to
          assert against any prior landlord (including Landlord);


                                      J-2
<PAGE>

      (d) bound by any payment of rent or additional rent by Tenant to any prior
          landlord (including Landlord) for more than one month in advance;

      (e) bound by any amendment or modification of the Lease made without the
          written consent of Lender or such other purchaser, such consent not to
          be unreasonably withheld;

      (f) liable or responsible for, or with respect to, the retention,
          application and/or return to Tenant of any security deposit paid to
          any prior landlord (including Landlord), whether or not still held by
          such prior landlord, unless and until Lender or such other purchaser
          has actually received for its own account as landlord the full amount
          of such security deposit; or

      (g) bound by any provision in the Lease which obligates Landlord to erect
          or complete any building or to perform any construction work or to
          make any improvements to the Premises or to expand or rehabilitate any
          existing improvements or to restore any improvements following any
          casualty or taking or to make a future capital contribution to Tenant
          or to apply proceeds of casualty insurance or eminent domain awards
          other than as provided in the Mortgage.

5.    Acknowledgment of Assignment of Lease and Rent.  Tenant acknowledges that
      ----------------------------------------------
      it has notice that the Lease and the rent and all other sums due
      thereunder have been assigned or are to be assigned to Lender as security
      for the Loan secured by the Mortgage.  In the event that Lender notifies
      Tenant of a default under the Mortgage and demands that Tenant pay its
      rent and all other sums due under the Lease to Lender, Tenant agrees that
      it will honor such demand and pay its rent and all other sums due under
      the Lease directly to Lender or as otherwise required pursuant to such
      notice.

6.    Limited Liability.  Tenant acknowledges that in all events, the liability
      -----------------
      of Lender and any purchaser shall be limited and restricted to their
      interest in the Property and shall in no event exceed such interest.

7.    Lender's Right to Notice of Default and Option to Cure. Tenant will give
      ------------------------------------------------------
      written notice to Lender of any default by Landlord under the Lease by
      mailing a copy of the same by certified mail, postage prepaid, addressed
      as follows (or to such other address as may be specified from time to time
      by Lender to Tenant):

               To Lender:
                         -----------------------------
                         -----------------------------
                         -----------------------------
                         Attn.:
                               -----------------------
               with copies to:

                         -----------------------------
                         -----------------------------
                         Attn.:
                               -----------------------
      Upon such notice, Lender shall be permitted and shall have the option, in
      its sole and absolute discretion, to cure any such default during the
      period of time during which the Landlord would be permitted to cure such
      default, but in any event Lender shall have a period of thirty (30) days
      after the receipt of such notification to cure such default; provided,
      however, that in the event Lender is unable to cure the default by
      exercise of reasonable diligence within such 30-day period, Lender shall
      have such additional period of time as may be reasonably required to
      remedy such default with reasonable dispatch.

8.    Successors and Assigns. The provisions of this Agreement are binding upon
      ----------------------
      and shall inure to the benefit of the heirs, successors and assigns of the
      parties hereof.

$_____________                                              Bellevue, Washington
                                                           _______________,200__


FOR VALUE RECEIVED, iSHIP.COM, INC., a Washington corporation (the "Maker"),
promises to pay, in lawful money of the United States of America, to the order
of STERLING REALTY ORGANIZATION CO., a Washington corporation, ("Holder"), at
600 - 106th Avenue N.E., Suite 200, Bellevue, Washington 98004, or such other
place either within or without the State of Washington as Holder may designate
in writing from time to time, the principal sum of
______________________________ Dollars ($__________) or so much thereof as may
disbursed and outstanding, together with interest on the unpaid principal
balance from the date of each advance at the rate stated below, in accordance
with the terms of this Note.

1.   Interest Rate.  From the date of this Note, the principal balance shall
     bear interest at a rate equal to ___________________________ percent (___%)
     per annum.

2.   Payments.  Commencing on ___________________, and on the first day of each
     month thereafter through the Maturity Date, Maker shall pay to Holder
     payments of principal and interest in the amount _________________________
     Dollars ($_________), which amount is calculated based on the outstanding
     principal balance of this Note, the interest rate stated in paragraph 1
     above, and an amortization period of eight (8) years.  Maker will pay
     Holder at Holder's address shown above or at such other place as Holder may
     designate in writing.  Unless otherwise agreed or required by applicable
     law, payments will be applied first to accrued unpaid interest, and then to
     principal.  If not sooner paid, the outstanding principal balance of this
     Note and all accrued unpaid interest is due on _______________________ (the
     "Maturity Date")

3.   Prepayment.  This Note may be prepaid in whole or in part at any time
     without premium or penalty.

4.   Late Charge.  If any monthly payment is not made within ten (10) days of
     the due date, Maker shall pay to Holder on demand a late charge equal to
     three percent (3%) of the amount of the payment to defray the overhead
     expenses of Holder incident to the delay.

5.   Events of Default.  The failure to timely make any payment under this
     Note shall be an Event of Default.

6.   Remedies; Default Interest. Upon any Event of Default, Holder may declare
     the entire principal balance and all accrued interest immediately due and
     payable. Whether or not Holder exercises such option to accelerate, the
     entire principal balance and all accrued interest shall bear interest from
     the date of such Event of Default at a default rate of three percent (3%)
     above the interest rate otherwise payable under this Note. Default interest
     is payable on demand. Holder's failure to exercise any right or remedy
     shall not be a waiver of the right to exercise the same upon any subsequent
     Event of Default.

7.   Collection Expenses. Maker shall reimburse Holder on demand for all
     reasonable legal fees and other costs and expenses incurred in collecting
     or enforcing this Note. Such fees, costs and expenses shall include those
     incurred with or without suit and in any appeal, any proceedings under any
     present or future federal bankruptcy act or state receivership, and any
     post-judgment collection proceedings.

          postmark thereof.

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


                           COMMUNICATIONS SITE LEASE


THIS COMMUNICATIONS SITE LEASE (the "Site Lease") dated March 7, 2000, is
entered into by and between iSHIP.COM, INC., a Washington corporation
("Tenant"), having its principal place of business at 3545 Factoria Boulevard
S.E., Bellevue, Washington 98006, and STERLING REALTY ORGANIZATION CO., a
Washington corporation ("Landlord"), having its principal place of business 600-
106th Avenue N.E., Suite 200, Bellevue, Washington 98004.

1.  The Property.  Landlord is the owner of the building commonly known as
    Sterling Plaza II (the "Building"), constructed on that certain parcel of
    real property allocated in the State of Washington, County of King, City of
    Bellevue, located at 3545 Factoria Boulevard S.E., Bellevue, Washington
    98006 (the "Property").  A legal description of the Property is contained
    in Exhibit A attached to this Site Lease.
       ---------

2.  Lease of the Premises.

    (a)   Premises.  Landlord and Tenant have entered into that certain Lease
          --------
          Agreement dated March 7, 2000 (the "Office Lease") with respect to
          office premises located in the Building.  In connection therewith,
          Landlord has agreed that Tenant shall have the exclusive use of that
          portion of the roof of the Building generally described as follows:
          approximately ______square feet of space on the roof of the Building
          (equal to fifty percent (50%) of the usable area of the roof) for
          placement of Tenant's Communications Site (defined in paragraph 6
          below) Equipment (collectively the "Roof Premises").  A sketch of the
          Roof Premises is attached as Exhibit B to this Site Lease.  If at any
                                       ---------
          time during the term of this Site Lease, Tenant occupies less than two
          (2) full floors of the Building, then the area of the roof designated
          for Tenant's exclusive use shall decrease to twenty-five percent (25%)
          of the usable area of the roof of the Building, as shown on Exhibit C
                                                                      ---------
          attached to this Site Lease.

    (b)   Tenant Improvements.  Following the Commencement Date, Tenant shall
          -------------------
          have the right to construct the Communications Site as shown on the
          attached Exhibit B and in accordance with the detailed plans and
                   ---------
          specifications to be submitted by Tenant to Landlord and approved by
          Landlord prior to Tenant commencing any construction.  The design of
          the improvements to be constructed by Tenant shall be consistent with
          the design and construction of the Building.  In addition to plans and
          specifications, Tenant shall provide to Landlord such reports as
          Landlord, in Landlord's sole discretion, requires concerning the
          structural ability of the Building to support Tenant's proposed
          improvements or concerning the structural reinforcement required to
          support Tenant's proposed improvements.  All plans and specifications
          for Tenant's proposed improvements must be reviewed and approved by
          Landlord, Landlord's architect, communications consultant, structural
          engineer and roofing manufacturer; Tenant shall pay for all reasonable
          costs associated with such reviews.  Tenant shall obtain all necessary
          governmental approvals and permits prior to commencing construction
          and shall provide Landlord with ten (10) days notice prior to the
          start of construction.  Landlord may post notices of non-
          responsibility if it so chooses.  All Tenant contractors and
          subcontractors shall be duly licensed in the State of Washington and
          approved in advance by Landlord, such approval not to be unreasonably
          withheld.  All construction activities must be coordinated with
          Landlord or Landlord's agents.  If any damage to the Roof Premises is
          caused by the acts or omissions of Tenant's employees, contractors or
          agents during installation of the Equipment, Tenant shall repair any
          such damage and return the Roof Premises to the same


                                      N-1
<PAGE>

          condition as existed prior to the installation. If Tenant does not
          complete repairs to the satisfaction of the Landlord in a timely
          manner, then Landlord shall make such repairs as it deems necessary
          and such costs shall be paid by Tenant.

3.   Rent.  No rent shall be due from Tenant in connection with the Roof
     Premises.

4.   Term of Lease.  The term of this Site Lease shall, except with respect to
     the commencement date which is determined by the terms of Section 5 below,
     be for the same period of time as the Office Lease, as the same may expire,
     be terminated or be extended in accordance with the terms set forth
     therein.

5.   Commencement Date; Governmental Permits.  The term of this Site Lease shall
     commence on the first day of the month following Tenant's notice to
     Landlord in writing that Tenant has obtained all permits and approvals
     necessary for Tenant to be legally entitled to construct the communications
     site at the Roof Premises (the "Commencement Date").  Tenant shall be
     permitted to occupy the Roof Premises and commence construction of the
     Communications Site upon receipt of all such permits and approvals and
     notice to Landlord as required in paragraph 2.  Any pre-Commencement Date
     occupancy by Tenant shall be under all the terms and conditions of this
     Site Lease.

6.   Use of the Premises.  Tenant shall use the Roof Premises for the
     installation and maintenance of satellite dishes and/or antennas or
     comparable equipment used in connection with the operation of Tenant's
     business from the Premises (a "Communications Site").  The Communications
     Site, for purposes of this Site Lease, is a site at which radio, telephone,
     paging, wireless voice, data, and other communications equipment is
     installed and used to send and receive radio and other signals to and from
     wireless telephones and other radio, paging or computer devices to connect
     those signals to radio, telephone, or other communications facilities
     and/or devices either directly, by means of cables, or indirectly, by means
     of transmitting and receiving facilities approved by Landlord and located
     at the Roof Premises.  Tenant shall not use the Roof Premises for any other
     purposes without the written consent of Landlord.  Landlord shall at all
     times have the ability to audit, inspect and monitor Tenant's use of the
     Roof Premises, and Tenant shall cooperate in all ways reasonably requested
     by Landlord.  If Tenant's use of the Roof Premises increases the cost of
     the Landlord's insurance on the Building, Tenant shall promptly reimburse
     Landlord for such cost following receipt of an invoice therefor from
     Landlord.

7.   License.  Landlord hereby grants to Tenant for the duration of this Site
     Lease, a non-exclusive license in and over the common areas at the Property
     so that Tenant may have access to the Roof Premises (the "Access Areas")
     twenty-four (24) hours per day, seven (7) days per week.  Tenant shall not
     have access to the penthouse located on the roof of the Building without
     being accompanied by Landlord or Landlord's agent, and when on the roof of
     the Building, Tenant and its contractors shall use every effort to walk
     only on the catwalk areas.  The license granted to Tenant is for the
     purpose of installing, constructing, maintaining, restoring, replacing, and
     operating Tenant's equipment located within or on the Roof Premises or the
     Access Areas.  Except in the event of an emergency endangering persons or
     property, or in the event Tenant's signal, for any reason, is interrupted
     or lost, access to the Roof Premises shall be granted only at such times
     during normal business hours of the Building as is reasonable for Landlord
     or Landlord's agents, and then only upon the request of Landlord by Tenant
     or Tenant's agents, made reasonably in advance of the time for such access.
     Outside of normal business hours of the Building, Landlord may require a
     member of its security or maintenance staff to be present during such times
     as Tenant requires access to the Roof Premises.  Tenant shall reimburse
     Landlord for the cost of having a maintenance or security staff member
     present outside of normal business hours.

8.   Protections Against Ongoing Interference.  Following the effective date of
     this Site Lease, and promptly after such information is available to
     Tenant, Tenant shall inform Landlord in writing of its Communications Site
     requirements and signal frequencies, so as to allow Landlord (and tenants
     of Landlord) to determine whether any communications equipment they wish to
     install will create ongoing interference with Tenant's Communications Site.
     Tenant acknowledges that until such time as Tenant has notified Landlord of
     its specific frequency range, Landlord cannot guarantee the appropriateness
     of the


                                      N-2
<PAGE>

     Roof Premises as the location for Tenant's Communications Site. Tenant
     further acknowledges that Landlord has prior obligations to the tenants
     (the "Existing Tenants") of other properties owned by Landlord which are
     located adjacent to the Property, and that Landlord cannot allow Tenant's
     equipment and/or frequencies to interfere with the equipment and/or
     frequencies currently maintained by the Existing Tenants. Therefore, the
     installations of communications equipment, or use of a specific frequency
     by Tenant, or by any other tenant, is subject to the compatibility of such
     party's equipment and frequencies with that of communications equipment and
     frequencies then located on the Property or maintained by an Existing
     Tenant or of which Landlord has been adequately notified as required by
     this paragraph 8. Either Tenant or any other tenant desiring to locate new
     equipment or use additional frequencies shall, at that party's sole cost
     and expense, conduct such studies as are necessary to determine potential
     interference with then-existing equipment and frequencies and/or FCC
     permitted signals or frequencies of Tenant, other tenants of the Property
     and the Existing Tenants. Any change of frequency or additional frequencies
     to be used by Tenant shall be allowed, provided Tenant provides written
     notice of the same to Landlord. Landlord will not grant a lease to any
     party for use of the Property if such use would interfere with Tenant's
     ability to physically operate its Communications Site for the use described
     herein, as specifically approved in writing by Landlord and as Tenant's
     Communications Site exists immediately prior to the date on which any new
     lease is entered into by Landlord for the installation of communications
     equipment on the roof of the Building. Any future lease of the Property
     which permits the installation of communication equipment shall be
     conditioned upon not interfering with Tenant's operation of the
     Communications Site, based on Tenant's written notification to Landlord, as
     to its signal frequencies and any changes or additions thereto, as of the
     date of such lease, and any potential tenant shall be required to conduct
     an intermodulation study to determine potential interference with Tenant's
     signal and transmission. Without limiting any other remedy, in law or
     equity, Tenant shall have the right to terminate this Site Lease upon
     thirty (30) days' written notice in the event its reception or transmission
     is interfered with on an ongoing basis by other antenna equipment, or
     obstacles constructed or operated in Tenant's reception or transmission
     paths located upon or over Landlord's Property. Such termination shall not
     be the basis for any abatement of rent under the Office Lease.

9.   Damage and Destruction.  If the Roof Premises are, in whole or in part,
     damaged or destroyed, then there shall be no abatement of rent under the
     Office Lease.  If the Roof Premises are only partially destroyed and still
     usable as a Communications Site, Landlord shall, within a reasonable time,
     repair the Roof Premises such that the Roof Premises are again as fully
     usable by Tenant as they were before such partial damage or destruction.
     Unless such partial damage or destruction is caused by Landlord, Landlord's
     agents or employees, Landlord shall be obligated to repair or replace the
     Roof Premises only, excluding any tenant improvements constructed,
     installed, or placed onto the Roof Premises by Tenant.  A decision as to
     whether partially destroyed or partially condemned Premises are still
     usable as a Communications Site (for the purposes of this paragraph and of
     paragraph 10 below), shall be made jointly by Landlord and Tenant, and, if
     they cannot agree, by an arbitrator reasonably acceptable to both parties.
     If the Roof Premises are wholly destroyed, then Landlord shall inform
     Tenant, within sixty (60) days after the date of such destruction, whether
     it intends to restore the Roof Premises.

10.  Condemnation.  If all or part of the Roof Premises is taken by condemnation
     such that the Roof Premises are no longer usable for construction of or
     operation as a Communications Site, this Site Lease shall terminate unless
     Tenant's equipment and improvements can be relocated to another position at
     the Property mutually acceptable to Tenant and Landlord.  Tenant shall be
     entitled only to that portion of the proceeds of condemnation which is
     directly attributable to the value of Tenant's equipment and improvements,
     and the cost of relocation, and under no circumstances shall Tenant receive
     any compensation for the value of the leasehold estate created by this Site
     Lease.

11.  Relocation of System by Landlord.  Upon not less than thirty (30) days
     advance written notice to Tenant from Landlord, Landlord may, at Landlord's
     expense, relocate Tenant's Communications Site to another location on the
     roof of the Building if Landlord, in its good faith judgment, deems such
     relocation necessary; provided, however, that Landlord may not do so if the
     result of the relocation would cause Tenant to lose, or experience
     degraded, transmission or reception.


                                      N-3

12.  Access by Landlord.  Landlord shall have access to the Roof Premises at all
     times, and Landlord agrees to give Tenant such notice as is reasonable
     under the circumstances.

13.  Termination by Landlord.  Landlord may terminate this Lease upon the
     occurrence of any of the following: (a) the termination of the Office
     Lease; (b) failure by Tenant to comply with any material term, condition or
     covenant of this Site Lease, if such failure is not cured within thirty
     (30) days after written notice thereof to Tenant, or in the event of a cure
     which requires in excess of thirty (30) days to complete, if Tenant has not
     commenced such cure within thirty (30) days of such notice and is not
     diligently prosecuting said cure to completion; (c) if Tenant becomes
     insolvent, or makes a transfer in fraud of creditors, or makes an
     assignment for the benefit of creditors, or files a petition under any
     section or chapter of the federal Bankruptcy code, as amended, or under any
     similar law or statute of the United States or any state thereof, or is
     adjudged bankrupt or insolvent in proceedings filed against Tenant
     thereunder, or if a receiver or trustee is appointed for all or
     substantially all of the assets of Tenant due to Tenant's insolvency; or
     (d) during any Option Term, Landlord decides to demolish or reconfigure the
     Building in a manner that will impact the Roof Premises and provides Tenant
     with written notice of termination of this Lease at least twelve (12)
     months prior to the termination date.

14.  Termination by Tenant.  Tenant may terminate this Lease at any time upon
     thirty (30) days written notice to Landlord.

15.  Warranties and Covenants of Tenant.  Tenant warrants and covenants that
     throughout the term of this Site Lease, Tenant shall maintain comprehensive
     liability insurance, naming Landlord as an additional insured, protecting
     and indemnifying Landlord and Tenant against claims and liabilities for
     injury, damage to persons or property or for the loss of life or of
     property occurring upon the Roof Premises, Access Areas or other parts of
     Landlord's property resulting from Tenant's use of Landlord's property,
     including those resulting from any negligent act or omission of Tenant, its
     employees, agents, contractors, and subcontractors.  Such insurance shall
     afford minimum protection of not less than One Million Dollars ($1,000,000)
     for injury to or death of any one person, Three Million Dollars
     ($3,000,000) for injury to or death of two or more persons, One Million
     Dollars ($1,000,000) for property damage, and Five Million Dollars
     ($5,000,000) for excess liability in the form of umbrella liability
     coverage.  Tenant shall also maintain personal property insurance in an
     amount sufficient to fully protect all personal property, fixtures and
     tenant improvements constructed, owned or controlled by Tenant and brought
     upon Landlord's property from theft, fire or other loss or damage while
     upon the Property.  Tenant shall provide to Landlord a certificate
     indicating the applicable coverage prior to the Commencement Date of the
     Lease and as necessary throughout the term of the Lease to evidence to
     Landlord's satisfaction that coverage remains in full force and effect.
     All insurance shall be procured from insurance companies satisfactory to
     Landlord.  Tenant shall maintain the Roof Premises in a clean, safe and
     sanitary condition throughout the term of this Site Lease.

16.  Liability and Indemnification.  Tenant shall at all times comply with all
     laws and ordinances and all rules and regulations of municipal, state, and
     federal governmental authorities relating to the installation, maintenance,
     height, location, use, operation, and removal of improvements authorized
     herein, whether such laws, ordinances, rules and regulations are directed
     to Tenant or to Landlord, and shall fully indemnify Landlord against any
     loss, cost or expense which may be sustained or incurred by Landlord as a
     result of the installation, operation, maintenance or removal of such
     improvements, including but not limited to any damage to the roof of the
     Building, and any damage or injury to Landlord, Landlord's agents or
     employees, or other tenants or tenants' employees, agents or invitees of
     the Building caused by Tenant's operation of its Communications Site.
     Except for the negligent acts or willful misconduct of Landlord and
     Landlord's agents or employees, Landlord shall not be liable to Tenant for
     any loss or damages arising out of personal injuries or property damage on
     the Roof Premises or Access Areas.  Tenant shall be fully responsible for
     any radio signal or electrical interference that its equipment may cause
     with respect to any other radio or telecommunications system authorized or
     licensed by the Federal Communications Commission and existing on the
     Commencement Date or any date thereafter.

17.  Title To and Removal of Tenant's Equipment.  Title to Tenant's equipment,
     and all improvements installed at and affixed to the Roof Premises or the
     Property by Tenant shall be and shall remain the property of Tenant.
     Landlord hereby waives any lien rights it may have or acquire with respect
     to Tenant's property and shall promptly execute any document reasonably
     required by any supplier, lessor, or lender of such property which waives
     any rights Landlord may have or acquire with respect thereto.  Tenant may,
     at any time, including any time it vacates the Roof Premises, remove
     Tenant's improvements, equipment, fixtures, and all of Tenant's personal
     property from the Roof Premises, and Tenant shall promptly restore the
     property and repair any damage thereto caused by such removal.  Tenant
     shall remove any structural improvements installed to support Tenant's
     equipment upon Landlord's request to do so.  Any of Tenant's property
     remaining on the Roof Premises after the expiration or earlier termination
     of this Site Lease or after Tenant's vacation or abandonment of the Roof
     Premises ("Abandoned Property") will be deemed to have been abandoned and
     to have become the property of Landlord to dispose of at Landlord's
     discretion.  Tenant shall reimburse Landlord for any of Landlord's court
     costs, attorneys' fees, and storage charges related to Abandoned Property.
     Landlord may, at its option, sell Abandoned Property at private sale
     following written notice to Tenant thereof, for such price as Landlord may
     obtain, and apply the proceeds of such sale to any amounts due under this
     Site Lease from Tenant to Landlord, including expenses incident to the
     removal and sale of Abandoned Property, or Landlord may otherwise dispose
     of Abandoned Property.

18.  Surrender.  Upon termination of this Lease, Tenant shall remove the
     equipment and improvements installed at the Roof Premises by Tenant as set
     forth in paragraph 16.  Tenant shall repair and restore any damage to the
     Roof Premises caused by such removal, and shall surrender the Roof Premises
     in as good order and condition as when first occupied by Tenant, normal
     wear and tear and damage by fire or other casualty excepted.

19.  Assignment and Subletting.  Tenant's right to use the Roof Premises is
     personal to Tenant (or Tenant's successor-in-interest through merger), and
     Tenant may not assign this Site Lease or sublease all or any portion of the
     Roof Premises to a third party except as permitted by the terms of Section
     35 of the Lease.

20.  Tenant's Costs.  If Tenant fails to obtain all permits necessary for the
     construction of the Communications Site such that the term of this Site
     Lease never commences, Tenant shall pay to Landlord an amount equal to all
     costs incurred by Landlord for the preparation and negotiation of this Site
     Lease and all costs associated with Landlord's review of the plans and
     specifications for construction of Tenant's Communications Site on the Roof
     Premises.

21.  Notices and Other Communications.  Every notice required by this Lease
     shall be delivered either by (a) personal delivery, or (b) postage prepaid
     return receipt requested certified mail addressed to the party for whom

     Landlord and Landlord's officers, directors, partners, affiliates, agents
     and employees against any and all losses, liabilities, claims and/or costs

     and/or reproductive toxicity, and/or any substance, chemical or waste that
     is identified as hazardous, toxic or dangerous in any applicable federal,
     state or local law or regulation.  Landlord represents that, to the best of
     its knowledge as of the date of this Site Lease, there is no Hazardous
     Material on the Property in violation of any applicable law or regulation.

24.  Waivers.  Any waiver of any right under this Site Lease must be in writing
     and signed by the wavering party.

                         Rules and Regulations of Lease
                         ------------------------------

Tenant recognizes that other tenants will be leasing antenna and equipment space
from Landlord, and that effective use of the Property requires cooperation and
good faith between itself, other tenants, and Landlord.  Therefore, to avoid
objectionable interference, engage in proper Telecommunications Activity, and
facilitate the purposes of all leases, Tenant shall adhere to the following
Rules and Regulations, which Landlord may modify from time to time upon advance
notice to Tenant.

1.  Definitions.

    a)   Responsible Tenant:  Means the tenant responsible for correcting
         objectionable interference.

    b)   Telecommunications Activity:  Means the conduct of transmissions
         (e.g., Amplitude modulated aural transmission or frequency modulated
         aural or visual transmission) from the Property upon a single
         frequency at any one time assigned to a tenant by the Federal
         Communications Commission ("FCC").  If a tenant conducts the same type
         of transmission on two or more assigned frequencies, each of them
         shall constitute a separate Telecommunication Activity.

    c)   Transmission:  Means the emission or reception of electromagnetic
         waves.

2.   Plans For Telecommunications Activity.  Prior to making any installations
     or material modifications of a Telecommunication Activity, every tenant
     shall submit plans and designs to Landlord.  Landlord shall have twenty
     (20) days thereafter to approve or disapprove the plans and designs, based
     on the effect the installation may have on the Property and its structural
     components and the potential for objectionable interference.

3.   Testing Required Prior to Installation.  Prior to the installation of any
     equipment required for a Telecommunication Activity, Tenant, at its
     expense, shall conduct all tests that Landlord deems reasonably appropriate
     or necessary to determine that Tenant's proposed Telecommunication Activity
     can be conducted without causing objectionable interference to any
     Telecommunication Activity then being conducted by another tenant.  The
     tests conducted shall be of the type then generally recognized as
     appropriate for such purposes.  Following receipt by Landlord of acceptable
     test results, Tenant shall coordinate with Landlord as to the exact time of
     installation of the equipment required for the approved Telecommunication
     Activity.  Tenant agrees that only authorized engineers, employees, or
     contractors, as reasonably selected by Tenant, will be permitted to enter
     the Property for the purpose of installing, modifying, or maintaining
     Tenant's facilities.  Tenant further agrees that all engineers,
     contractors, or subcontractors hired by Tenant for the purpose of
     installing any equipment on the Property will by duly licensed in the State
     of Washington and approved by Landlord, which approval shall not be
     unreasonably withheld.

4.   Subsequent Modifications to Telecommunication Activity.  All modifications
     or subsequent changes in Tenant's Telecommunication Activity shall be
     subject to provisions of paragraphs 2 and 3.

5.   Objectionable Interference.  Objectionable interference to a
     Telecommunication Activity may be caused by:

     a) Initiation of a Telecommunication Activity, or the installation of
        equipment in preparation for the initiation of a Telecommunication
        Activity, without first complying with the provisions of paragraphs 2
        and 3 above. With respect to the initial operation of a
        Telecommunication Activity, that activity may constitute objectionable
        interference even if such interference is not discovered

                                     N-13

<PAGE>

        until after a tenant's Telecommunication Activity is initiated. This
        shall be referred to as Type 1 interference.

    b)  The failure by Tenant to maintain its equipment properly, to replace
        defective equipment, or to operate its Telecommunication Activity in
        accordance with good engineering practices. This shall be referred to as
        Type 2 interference.

6.   Notice Of Need For Corrective Action.  If Tenant is of the opinion that
     there is objectionable interference to its Telecommunications Activity, and
     that another tenant is under obligation to correct said interference, it
     may, without prejudice to its other remedies, give written notice to
     Landlord and the Responsible Tenant(s).  The Responsible Tenant shall,
     within three (3) days of receiving such notice (or such longer period as
     consented to in writing by Tenant), comply with the provisions set forth
     herein regarding corrective action for objectionable interference. If the
     Responsible Tenant fails to respond as required, then the rights granted by
     Landlord to the Responsible Tenant shall terminate as to the interfering
     Telecommunication Activity.

7.   Corrective Action.  If objectionable interference results from either Type
     1 or Type 2 interference, then the Responsible Tenant shall take all
     necessary corrective actions to eliminate the objectionable interference.
     If objectionable interference arises with Telecommunication Activity
     initiated in accordance with the Responsible Tenant's lease and these
     Results and Regulations, the Responsible Tenant shall:

       a) Immediately discontinue the interfering activity until such
          interference can be fully corrected; or

       b) Transfer its Telecommunication Activity to a temporary location and/or
          equipment operating configuration if objectionable interference will
          be eliminated by doing so.

     Whenever a Responsible Tenant discontinues a Telecommunication Activity or
     transfers to a temporary location pursuant to this paragraph, it shall not
     resume such Telecommunication Activity or transfer such Telecommunication
     Activity from the temporary location to its previous, permanent location
     until it fully complies with the conditions provided for engaging in the
     initial operation of a Telecommunication Activity.

8.   Protective Devices.  Tenant may request that Landlord, at Tenant's expense,
     attach protective devices to the equipment of other tenants.  Tenant agrees
     that other tenants may, upon written approval of Tenant, which approval
     shall not be unreasonably withheld, attach protective devices to Tenant's
     equipment, provided that no objectionable interference occurs in the
     conduct or use of any of Tenant's equipment or Telecommunication Activity.
     The tenant attaching such equipment shall promptly have such protective
     devices removed if objectionable interference results at any time.

9.   FCC Hearings.  Nothing herein shall be deemed to limit the right of Tenant
     to request hearings before the FCC, or to appear before the FCC in any
     hearings held in such proceedings, or to oppose any application to the FCC
     filed by any other tenant as a result of such proceedings.

10.  Compliance with FCC Rules and Regulations.  If Tenant's operations or
     Telecommunication Activities fail to comply with FCC rules and regulations,
     and objectionable interference arises because of such noncompliance, then
     Tenant shall not be entitled to the protection of these Rules and
     Regulations regarding objectionable interference, until it fully complies
     with FCC standards.

11.  Good Faith Conduct.  Tenant shall conduct its Telecommunications Activity
     in good faith and in accordance with the purposes and intent of its lease
     for a portion of the Property. Tenant shall cooperate with other tenants to
     anticipate and prevent objectionable interference.

12.  Interference with Third Parties.  In the event a tenant's Telecommunication
     Activities result in interference with transmission or reception of signals
     or other services or activities by a party other than tenant, and if a
     legal obligation exists to correct such interference, then the
     responsibility for and expense of correcting such interference with be
     borne by the tenant or tenants involved, in accordance with principles
     established herein for corrective action.

to those in Sections 2(a)(i) through 2(a)(vi) shall be subject to the same
limitations and requirements as to precautions reasonably acceptable to Stamps
as are stated in the corresponding provisions above.

     (b) Exclusivity
         -----------

         (i) Exclusivity in the Travel and Events Fields of Use. The license
             --------------------------------------------------
granted to EncrypTix pursuant to Section 2(a) is exclusive with respect to the
Travel and Events Fields of Use for a period of [***]* years from the Effective
Date; provided that to maintain exclusivity, EncrypTix must continue as a
      --------
going concern and maintain its ability to pay its debts as they become
due.

         (ii) Termination of Exclusivity. At any time that EncrypTix fails to
              --------------------------
meet the criteria to maintain exclusivity set forth in Section 2(b)(i), the
license of the Stamps Technology pursuant to Section 2(a) shall become a non-
exclusive license in the Travel and Events Fields of Use.

         (iii) Exceptions to Exclusivity. EncrypTix shall be entitled to enforce
the exclusivity set forth in this Section 2(b) against all Third Parties and
Stamps, with the following limited exceptions:

               (A) Each of Stamps' existing (as of the Effective Date) non-
exclusive licenses, as set forth on Schedule 2(b)(iii)(A) attached hereto (the
                                             ------------
"Existing Agreements"), shall remain in full force and effect until its
expiration and the expiration of any renewal periods exercisable and exercised
by the respective licensees, and EncrypTix shall not be entitled to enforce its
exclusivity hereunder with respect to such Existing Agreements; provided that
                                                                --------
Stamps shall not exercise any options to extend such licenses into any fields of
use other than those fields of use licensed thereunder as of the Effective Date
or to renew or extend the term of any such license;

               (B) Stamps shall have the right, with prompt notice to Encryptix,

Parties [***]* involving the Stamps Technology;
         ---
               (C) Stamps shall have the right, with prompt notice to Encryptix,
 to [***]*; and
     ---

               (D) Stamps shall retain the right to: (i) use the Stamps
Technology and all Derivative Works thereof in the Travel and Events Fields of
Use for the sole purpose of fulfilling its

obligations under this Agreement or other agreements with EncrypTix and/or to
provide EncrypTix with technical support and maintenance services; (ii) use the
Stamps Technology and all Derivative Works thereof for all purposes outside of
the Travel and Events Fields of Use; and (iii) copy, reproduce and create
Derivative Works of the Stamps Technology (provided that copying pursuant to
this clause (iii) shall not occur to permit, or in connection with, commercial
exploitation of the technology by Stamps in the Travel and Events Fields of Use
while exclusivity continues for that field of use).

               (iv) Non-Exclusivity of Financial Services Field of Use;
                    ---------------------------------------------------
Potential Termination. The license granted to EncrypTix pursuant to Section 2(a)
- ---------------------
is a non-exclusive license of rights in and to the Stamps Technology in the
Financial Services Field of Use (except that, if an activity should exist that
is within both the Travel and Events Fields of Use an the Financial Services
Field of Use, the license will be exclusive as to that activity). Stamps may
terminate EncrypTix' license in the Financial Services Field of Use in the event
that EncrypTix: (i) fails to obtain no less than twenty million dollars
($20,000,000) of equity financing prior to the first anniversary of the
Effective Date; or (ii) fails at any time to continue as a going concern or to
maintain its ability to pay its debts as they become due.

               (v) Extension of Exclusivity in the Travel and Events Fields of
                   -----------------------------------------------------------
Use. Upon the expiration of the [***]* year period of exclusivity defined in
- ----
Section 2(b)(i), the license granted to EncrypTix pursuant to Section 2(a) shall
remain exclusive with respect to any exclusive field of use (i.e., the Travel
Field of Use or the Events Field of Use, or, if applicable, both of those fields
of use) for an additional [***]* (to the extent that such exclusivity was not
                           ---
theretofore terminated pursuant to Section 2(b)(i) or 2(b)(ii)) if, in [***]*,
                                                                        ---
EncrypTix shall have issued more than [***]* tickets in revenue-generating (for
                                       ---
EncrypTix) issuances in such field of use.

         (c) Sublicensed Matter.
             ------------------

               (i) To the extent that any of the Stamps Technology is acquired
by or licensed to Stamps from any Third Party licensor that is not under direct
or indirect common ownership with Stamps ("Third Party Technology"), the grant
of license or sublicense rights to EncrypTix with respect to all Third Party
Technology is subject to Stamps' right under its license from each respective
Third Party licensor (the "Primary License") to sublicense the Third Party
Technology, and, consistent with the rights granted to EncrypTix under Section
2.1(a) but subject to the further provisions in this paragraph, Stamps shall
grant to EncrypTix such rights as the Primary License permits. Unless EncrypTix
declines all rights under licenses of Third Party Technology as provided in the
following sentence, EncrypTix shall pay or reimburse Stamps for appropriately
prorated expenses and acquisition costs and any incremental royalties which
Stamps becomes obligated to pay to such Third Party licensor by reason of
EncrypTix' license or sublicense of, or exploitation of, the Third Party
Technology. In connection with future acquisitions of Third Party Technology,
Stamps will, to the extent consistent with any applicable confidentiality
requirements and its other contractual commitments, provide EncrypTix with (i) a
copy of such new license agreements and information on the subject technology
and (ii) a period of ten (10) business days to decline, by notice to Stamps, any
rights thereunder; in which case, notwithstanding the foregoing provisions of
this Section 2, EncrypTix shall have no rights to the Third Party Technology
licensed to Stamps thereunder.

<PAGE>

     (ii) Stamps will maintain accurate records with regard to its obligations
and payments for Third Party Technology and the amounts due from EncrypTix in
connection with Third Party Technology. For the purpose verifying its payment
obligations in connection with Third Party Technology, EncrypTix (or its
representative) will have the right to conduct a reasonable inspection of the
portions of such records that are relevant to those EncrypTix' payment
obligations. Any such audit may be conducted after ten (10) business days prior
written notice to Stamps. EncrypTix shall bear the expense of any audit
conducted pursuant to this paragraph unless such audit shows overcharges in the
amounts reported as payable to Stamps or actually paid to Stamps by EncrypTix
for Third Party Technology for any quarterly period in excess of the greater of
(a) ten percent (10%) of the actual or reported amounts paid or payable to
Stamps for Third Party Technology for such period and (b) Five Thousand Dollars
($5,000.00), in which event Stamps shall bear the reasonable expenses of the
audit.

     (d) Additional Field of Use.  During the term of this license, EncrypTix
         -----------------------
shall have the right to petition Stamps to expand the license granted hereunder
to specific fields of use in addition to the Travel and Events Fields of Use and
the Financial Services Field of Use. Stamps shall consider such petitions in
good faith, however, any grant of additional fields of use (whether exclusive or
            -------
non-exclusive) will be at Stamps' sole discretion and for additional
compensation.

     (e) Restrictions.  EncrypTix shall not (and shall not allow any Third Party
         ------------
to): (i) decompile, disassemble, or otherwise reverse engineer or attempt to
reconstruct or discover any source code, underlying ideas, or algorithms of the
Stamps Technology by any means whatsoever (except to the extent that applicable
law prohibits reverse engineering restrictions), (ii) remove any product
identification, copyright, patent or other notices, (iii) except to the extent
expressly authorized in this Section 2, modify or incorporate into or with other
software or create a derivative work of any part of the Stamps Technology, or
(iv) sublicense or assign any rights hereunder to any Third Party (including
without limitation, end-user licenses) unless otherwise expressly permitted
under this Section 2.

     (f) Patent Markings and Copyright Notices.  EncrypTix shall reproduce on or
         -------------------------------------
within all products, software, webpages and other media incorporating the Stamps
Technology and on any related media all patent markings and copyright notices as
supplied by Stamps and such additional notices as may reasonably be requested by
Stamps.

     (g) Exception to License.  Notwithstanding anything else in this Agreement,
         --------------------
no license whatsoever is or will be conveyed or granted by this Agreement as to:

         (i) the source code version of any Stamps Technology that consist(s) of
[***]*, provided that nothing in this clause "i" limits EncrypTix's rights to
 ---
obtain object code versions of the foregoing;"

         (ii) a new version of, or a replacement for, an item of source code not
furnished to EncrypTix pursuant to the preceding clause "i" provided that Stamps
                                                            -------------
will consult with EncrypTix and may include in the license new source code that
would be included but for this restriction unless Stamps determines that it has
legitimate security or other reasons not to do so, and provided that nothing in
this clause "ii" limits EncrypTix's rights to obtain object code versions of the
foregoing; or

         (iii) as to which licensing and provision to EncrypTix as provided in
this Agreement would (A) violate applicable laws or regulations including,
without limitation, Postal Service or Department of Commerce laws or
regulations; (B) violate contractual arrangements between Stamps and shippers or
other entities connected with the Mail and Postage Field of Use; or (C) create a
meaningful risk of a security violation.

EncrypTix shall own all right, title and interest in and to all intellectual
property created by EncrypTix (the "EncrypTix Technology"). EncrypTix hereby
grants to Stamps a non-exclusive, fully paid-up, royalty free, perpetual,
irrevocable and worldwide license, with right to sublicense, to use, reproduce,

and Shipping Field of Use.

6. CONFIDENTIAL INFORMATION

     (a) Treatment of Confidential Information.  Stamps and EncrypTix recognize
         -------------------------------------
that, in connection with the preparation or performance of this Agreement, each
of them may disclose to the other its Confidential Information, or each may
obtain Confidential Information of the other through preparation of or
performance under this Agreement, including by the creation of materials and the
development of technology and techniques that are not generally known. Except as
permitted in connection with the license rights granted pursuant to this
Agreement, a party who obtains any Confidential Information of the other agrees
to maintain the confidential status of such Confidential Information, not to use
any such Confidential Information for any purpose other than the purpose for
which it was originally disclosed to the receiving party, to disclose such
Confidential Information only to those of its employees having a need to know
such information, and not to disclose any of such Confidential Information to
any Third Party other than consultants, contractors and advisors under a written
obligation to keep such information confidential and to use it only for the
purposes set forth above. Neither Stamps and EncrypTix shall disclose the
other's Confidential Information to any person except on a "need-to-know" basis.

     (b) Stamps Security Policies.  EncrypTix shall comply at all times with
         ------------------------
Stamps' security policies as they may be amended from time to time. Stamps shall
keep EncrypTix reasonably advised of Stamps security policies and changes
therein.

     (c) Required Disclosure.  The Parties recognize that each may be required
         -------------------
by law or order of a court or other governmental authority, SEC regulations, or
the like, to disclose the other's

                                       9
<PAGE>

Confidential Information, and that each shall endeavor to stop or limit such
disclosure and afford the other the opportunity to do so. Each party shall
immediately give the other party written notice of any anticipated disclosure
pursuant to this Section 6(c) and will provide reasonable assistance to the
other party, at the other party's expense, in resisting such disclosure. Without
limiting the foregoing, any party making filings with the Securities and
Exchange Commission shall include a copy of this Agreement only if and to the
extent required and shall withhold, or use its best efforts to prevent public
disclosure of, Schedule 2(g) hereto. In the case of filings made by EncrypTix,
EncrypTix shall also consult with Stamps, withhold Schedule 2(g) if possible,
seek confidential treatment of Schedule 2(g) if it cannot be withheld entirely,
and, to the extent necessary to secure confidential treatment of the material
therein that Stamps seeks to protect, redact such schedule.

     (d) Third-party Confidential Information. Any confidential information of a
         ------------------------------------
third party disclosed by a party to the other shall be considered Confidential
Information hereunder and shall be subject to such additional restrictions as
may be imposed by such third party on the discloser and communicated in writing
by the discloser to the recipient.

     (e) Injunctive Relief. Each party agrees that if a court of competent
         -----------------
jurisdiction determines that one party has breached, or attempted or threatened
to breach, any of its confidentiality obligations to the other party or its
proprietary rights, such other party will be entitled to obtain appropriate
injunctive relief and other measures restraining further attempted or threatened
breaches of such obligations.

7. ENFORCEMENT AND DEFENSE

     (a) Control.
         -------

         (i) Stamps shall have the right, but not the obligation, to control the
investigation, enforcement, defense and settlement of any action with respect to
the Stamps Technology (including any action in which the ownership, validity, or
enforceability of any of the Stamps Technology is or may be put at issue or in
which any third party asserts or may assert that use of the Stamps Technology
(including Derivative Works prepared by or for EncrypTix pursuant to
authorization in this License Agreement) by Stamps or by EncrypTix infringes or
will infringe the intellectual property rights of one or more third parties)
provided that, with respect to copyrights and trade secrets only, and only for
- --------
claims within the Travel and Events Fields of Use, EncrypTix shall have the
right, at its own cost and expense, to participate in such action with counsel
of its choice.  Except as provided in Section 2(c)(i), any settlement that (A)
grants to third parties any rights to the Stamps Technology in the Travel and
Events Fields of Use, or (B) that limits any of EncrypTix' rights in any
Licensed Fields of Use, shall be subject to EncrypTix' prior written consent,
which shall not be unreasonably withheld.

         (ii) If Stamps elects not to pursue any enforcement or defense of an
action referred to in the first sentence of the immediately preceding paragraph
"i", EncrypTix shall have the right to pursue such enforcement or defense on its
own, solely with respect the validity and use of the Stamps Technology in the
Licensed Fields of Use, including the settlement of any claims solely within the
Licensed Fields of Use. Any settlements that may affect the Stamps Technology
outside of the Licensed Fields of Use will require Stamps' prior written
consent, which shall not be unreasonably withheld.

     (b) Notice.  Each party shall provide the other prompt notice of any claims
         ------
of infringement of which such party becomes aware.

                                       10
<PAGE>

     (c) Assistance.  Each party will provide the other all assistance
         ----------
reasonably necessary to enforce or defend the Stamps Technology.

     (d) Sharing of Economics. If EncrypTix participates in an action with
         --------------------
respect to the Stamps Technology, then Stamps and EncrypTix will share equitably
the benefits (net of their respective burdens) of such enforcement action, such
sharing to reflect: (i) the total benefits received collectively by Stamps and
EncrypTix as a result of the action (including any appeals, etc.) and (ii) the
extent to which those benefits reflected the efforts and contributions made in
such action by Stamps or by EncrypTix respectively.

8. TERM AND TERMINATION

     (a) Term.  Unless earlier terminated under the provisions of this Section,
         ----
this Agreement shall remain in full force and effect perpetually.

     (b) Termination for Breach Generally.
         --------------------------------

         (i) Notwithstanding the provisions of Section 8(a), this Agreement may
be terminated by either party (A) following a determination by the arbitrator
pursuant to the expedited arbitration procedures set forth in Schedule 8(b),
that the Terminating Party (as defined in Schedule 8(b)) would be likely to
prevail at a full trial on the merits on the claim that the Responding Party (as
there defined) has committed a material breach of the Agreement, unless (i) the
breach is curable and (ii) the Responding Party provides notice of its intent to
cure it and such cure is effected within the time stated in paragraph "9" of
Schedule 8(b) or (B) after a judicial declaration or finding to the effect of
the determination referred to in clause "A" above (or that a material breach has
actually occurred) unless the breach is curable, a notice of intent to cure is
provided thereafter, and the breach is cured as described (and pursuant to the
time provisions referred to) in clause "A.ii" above. A breach involving an
improper release of any Stamps Technology is not effectively cured unless and
until (A) such improper release ends and (B) Stamps receives reasonable
assurances that it will not suffer substantial injury or loss as a consequence
of such improper release and reasonable assurances that such a breach will not
occur again.

         (ii) The parties to this agreement will use their best efforts to agree
on the pre-approved arbitrators for purposes of Schedule 8(b) hereof within
fifteen calendar days after the date of this agreement and to list them on
Attachment B to Schedule 8(b) hereof. If at least four (4) such pre-approved
arbitrators are not so agreed upon in a specific order of priority as provided
in that Schedule before the time that one party or the other to this Agreement
delivers a written notice of material breach by the other party to such other
party (or within five business days thereafter, as to which the parties will use
their good faith efforts to agree), the requirement for an arbitrator's
determination prior to the commencement of a cure period and prior to a
termination of this Agreement for a material beach shall not apply. In that
event, if there actually has been a material breach by one party, the other
party may provide written notice thereof and terminate this agreement thirty
calendar days thereafter unless the breach is curable and is cured within that
thirty-day period.

         (iii) Nothing in Sections 8(a) or 8(b) shall limit the right of either
party to seek and obtain judicial relief including, without limitation: (a)
injunctive or other judicial relief to prevent or halt an improper disclosure,
release, or use of either party's Intellectual Property Rights; (b) damages or
other relief for a breach of this Agreement; and (c) a declaration that a
material breach has occurred.

<PAGE>

     (c) Other Events of Early Termination.  Stamps may, in Stamps' sole and
         ---------------------------------
absolute discretion, terminate this Agreement immediately by notice to EncrypTix
in the event of any of the following events: (i) except to the extent that an
opportunity for cure may be available in accordance with the last sentence of
this paragraph and a cure may be effected as provided there, any sublicense by
EncrypTix of rights to any Stamps Competitor other than a sublicense by
EncrypTix in the ordinary course of its business of only client-side software to
such entity as an end user consistent with the rights of EncrypTix in Section 2
hereof; (ii) any assignment of rights (including a Change of Control) by
EncrypTix to any Stamps Competitor; (iii) a Change of Control of EncrypTix at a
valuation of that entire company, on a fully diluted basis, of less than [***]*
dollars; and (iv) to the extent permitted under law, in the event that (A) any
proceeding shall be instituted by or against EncrypTix seeking to adjudicate it
bankrupt or insolvent, or seeking liquidation, winding up, reorganization,
arrangement, adjustment, protection, relief or composition of it or its debts
under any law relating to bankruptcy, insolvency or reorganization or relief of

receiver, trustee or other similar official for it or any substantial part of
its property (if such proceeding shall not have been dismissed without any such
relief within sixty days after such institution) or (B) EncrypTix shall take any
action to authorize any of the foregoing actions, or (C) EncrypTix shall be
unable at any time to pay its debts as they become due. In the case of clause
"i" above only, EncrypTix shall have an opportunity to cure the event allowing
termination if it provides notice to Stamps within twenty days after such
sublicense occurs; and such a cure shall be deemed to have been effected if,
within thirty (30) days after receipt of notice from Stamps that the licensee is
a Stamps Competitor, EncrypTix terminates such sublicense fully and effectively.

     (d) No Waiver or Release.  Termination of this Agreement by either party

release of either party from any liability for breach of such party's
obligations under this Agreement. No termination of this Agreement shall affect
the stock ownership or other rights or privileges obtained by Stamps in the
organization and capitalization of EncrypTix or, except as provided in other

possession or under its control, and shall furnish to the other party an
affidavit signed by an officer of its company certifying that to the best of its
knowledge, such delivery or destruction has been fully effected.

     (f) Survival of Certain Provisions.  Notwithstanding the termination of
         ------------------------------
the Agreement for any reason, the provisions of Sections 5; 6; 8(e) and (f); 9;
10; and 11(c), (d), (e), (h), (i) and (k) of this Agreement shall survive such

Infringement is based on a United States patent [***]*.

                                 Schedule 8(b)

                        Expedited Arbitration Procedures
                        --------------------------------

The following procedures are applicable solely for an expedited confirmation for
a material breach of the Agreement for purposes of Section 8(b).

     1.   A party desiring to terminate the Agreement for a material breach (the
          "Terminating Party") by the other party shell deliver a Demand for
          Expedited Determination ("Demand") to each of the following:

          a.   The opposite party to the Agreement (the "Responding Party"), and

          b.   Each of the individuals identified on Attachment B to this
               Schedule (the "Pre-Approved Arbitrators").

     2.   The Demand shall be executed by the Terminating Party and shall:

          a.   State that the Terminating Party demands an expedited
               determination regarding whether the Responding Party has
               committed a material breach of the Agreement and that this
               expedited determination is to be made under Section 8 of the
               Agreement and pursuant to the procedures set forth in this
               Schedule 8(b),

          b.   Provide reasonable notice of the events and circumstances
               believed to amount to the material breach, and

          c.   Be accompanied by (i) a Notice to Pre-Approved Arbitrators (the
               "Notice") which shall include, without limitation, substantially
               the statements set forth on Attachment A to this Schedule and
               (ii) a copy of this Agreement and its Schedules.

     3.   A single arbitrator shall decide the matter, and that person shall be
          the "available" Pre-Approved Arbitrator (as "available" is defined in
          the Notice) listed highest on Attachment B to this Schedule who
          responds to the parties as provided and within the time stated in the
          Notice. The parties to this Agreement agree to pay (initially in equal
          amounts but subject to an award of fees and costs to the prevailing
          party as provided below) the normal or customary charges of the
          arbitrator, to advance promptly and in equal amounts an aggregate
          amount requested by the arbitrator as a retainer (which shall be
          refundable if and to the extent not used), to replenish such retainer
          as used to the extent such arbitrator may request, and to execute such
          reasonably customary submission agreement as the arbitrator may
          request.

     4.   The arbitrator shall convene a hearing to determine the following
          issue: whether the Terminating Party would be likely to prevail at a
          full trial on the merits on the claim that the Responding Party has
          committed a material breach of the Agreement. The determination of the
          arbitrator shall be based upon the evidence and argument presented
          during the hearings as well as any written briefs and evidence that
          may be submitted to him/her (and the adverse party) prior to the
          hearing. The arbitrator shall select a date or dates for the hearing
          that are no less than ten days and no more than 20 days after delivery
          of the Demand. The hearing shall last not more than two full days, and
          the parties shall split equally the time available to them for the
          presentation of evidence. The
<PAGE>

     arbitrator shall also state in writing whether he believes that the
     position of one party in and in connection with the arbitration was
     significantly more justified and correct than that of the other party. If
     so, the party identified as having had the more justified and correct
     position shall be deemed the "prevailing party," and the arbitrator's
     statement so identifying such party shall amount to an award of the
     reasonable costs and fees incurred by such party in connection with the
     arbitration, which shall be paid by the other party within thirty days
     after delivery to it of reasonable summary documentation thereof.

5.   No later than five (5) calendar days before the hearing, each party may
     deliver to the other party a request for immediate production of such
     documents and/or other evidence or information as the requesting party
     believes are readily available to the other party and are important for
     preparation or presentation at the hearing. The requested documents shall
     be produced three (3) days prior to the hearing. The failure of either
     party to produce such available materials as are so requested by the other
     party shall not be grounds for sanctions but may be taken into
     consideration by the arbitrator to the extent, if any, that he/she believes
     it relevant.

6.   Not later than twenty-four (24) hours before the hearing, each party may
     file with the arbitrator and serve on the adverse party a brief and any
     supporting evidence, including declarations or documentary materials.

7.   The arbitrator's decision shall not be admissible in evidence or disclosed
     in any judicial proceeding; provided, however, that this provision shall
     not apply to any notice of the claimed breach (which shall not include the
     Demand) nor any action taken to cure the claimed breach.

8.   To the extent they are consistent with the provisions of the Agreement
     (including this Schedule and its attachments), the arbitration shall be
     conducted under and pursuant to the Commercial Arbitration Rules of the AAA
     (the "AAA Rules") (but need not be administered by the AAA except as
     hereinafter provided). In the event that the procedures in this Schedule
     and the attachments hereto fail to produce an arbitrator able to proceed
     with the arbitration or fail in another respect(s) to permit the expedited
     determination to be made as contemplated in the Agreement, a single
     arbitrator shall be appointed by the AAA and the proceeding shall be
     conducted under the AAA Rules consistent, to the extent possible, with the
     provisions of this Schedule. (The parties shall request that the AAA select
     as the arbitrator a single person having experience in technology or
     technology licensing disputes or in disputes involving computer software.)
     The arbitration conducted by the AAA shall be for the limited purposes
     specified in paragraph 4 hereof and shall be decided within 30 days. Once
     an arbitrator is selected, the timing of the arbitration and the procedures
     for the arbitration shall be as specified in paragraphs 4 through 7 hereof.

9.   If the arbitrator determines that the Terminating Party would be likely to
     prevail at a full trial on the merits on the claim that the Responding
     Party committed a material breach of the Agreement, and if the breach is
     curable, the Responding Party may decide whether to cure the confirmed
     breach and, if it is and such party provides notice to the Terminating
     Party within two (2) business days after receipt of the arbitrator's
     decision that it has elected to effect such a cure, shall have thirty (30)
     calendar days from the decision of the arbitrator to cure the breach.

10.  If the arbitrator determines that there was a material breach of this
     Agreement, the parties hereby express their willingness to have the
     arbitrator comment upon and offer suggestions as to whether the breach is
     curable and, if so, how the cure may be effected. Any such statements,
     however, shall be non- binding and inadmissible for any purposes in any
     separate proceedings. In no event,

                                       2
<PAGE>

     absent the written consent of both parties, shall there be continuing
     proceedings or additional hearings before the arbitrator on the nature or
     adequacy of the cure.

These expedited procedures are intended to allow either party to the Agreement
to terminate the Agreement without undue delay in the event of a material breach
by the other party while giving the other party the benefit of an outside
person's review of the matter prior to the termination and, if the breach is
curable, an opportunity to cure. These procedures are intended to be summary in
nature and non-exclusive. A party believing that the opposite party has
committed a material breach may institute judicial proceedings (for damages
and/or for declaratory, equitable, and/or other relief): (a) at the same time as
utilizing these summary procedures or (b) after trying unsuccessfully to utilize
these procedures or having begun but not having completed use of these
procedures or (c) after and notwithstanding an adverse determination by the
arbitrator in an expedited arbitration under these procedures. The doctrines of
collateral estoppel and res judicata shall be inapplicable to the findings,
rulings, and all other aspects of these summary proceedings.
